Installing GCC: Building

- - Now that GCC is configured, you are ready to build the compiler and - runtime libraries. !

Some commands executed when making the compiler may fail (return a ! nonzero status) and be ignored by make. These failures, which are often due to files that were not found, are expected, and can safely be ignored. ! !

It is normal to have compiler warnings when compiling certain files. Unless you are a GCC developer, you can generally ignore these warnings unless they cause compilation to fail. Developers should attempt to fix any warnings encountered, however they can temporarily continue past warnings-as-errors by specifying the configure flag ! --disable-werror. ! !

On certain old systems, defining certain environment variables such as ! CC can interfere with the functioning of make. ! !

If you encounter seemingly strange errors when trying to build the compiler in a directory other than the source directory, it could be because you have previously configured the compiler in the source directory. Make sure you have done all the necessary preparations. ! !

If you build GCC on a BSD system using a directory stored in an old System ! V file system, problems may occur in running fixincludes if the ! System V file system doesn't support symbolic links. These problems result in a failure to fix the declaration of size_t in ! sys/types.h. If you find that size_t is a signed type and that type mismatches occur, this could be the cause. ! !

The solution is not to use such a directory for building GCC. ! !

Similarly, when building from SVN or snapshots, or if you modify ! *.l files, you need the Flex lexical analyzer generator ! installed. If you do not modify *.l files, releases contain the Flex-generated files and you do not need Flex installed to build them. There is still one Flex-based lexical analyzer (part of the build machinery, not of GCC itself) that is used even if you only build the C front end. ! !

When building from SVN or snapshots, or if you modify Texinfo documentation, you need version 4.7 or later of Texinfo installed if you want Info documentation to be regenerated. Releases contain Info documentation pre-built for the unmodified documentation in the release. ! !

Building a native compiler

For a native build, the default configuration is to perform ! a 3-stage bootstrap of the compiler when ‘make’ is invoked. This will build the entire GCC system and ensure that it compiles ! itself correctly. It can be disabled with the --disable-bootstrap ! parameter to ‘configure’, but bootstrapping is suggested because the compiler will be tested more completely and could also have better performance. !

The bootstrapping process will complete the following steps: ! !

!

If you are short on disk space you might consider ‘make ! bootstrap-lean’ instead. The sequence of compilation is the same described above, but object files from the stage1 and stage2 of the 3-stage bootstrap of the compiler are deleted as soon as they are no longer needed. ! !

If you wish to use non-default GCC flags when compiling the stage2 and stage3 compilers, set BOOT_CFLAGS on the command line when ! doing ‘make’. For example, if you want to save additional space during the bootstrap and in the final installation as well, you can build the compiler binaries without debugging information as in the following example. This will save roughly 40% of disk space both for the bootstrap and the final installation. (Libraries will still contain debugging information.) ! 

     make BOOT_CFLAGS='-O' bootstrap
!
!

You can place non-default optimization flags into BOOT_CFLAGS; they ! are less well tested here than the default of ‘-g -O2’, but should still work. In a few cases, you may find that you need to specify special ! flags such as -msoft-float here to complete the bootstrap; or, if the native compiler miscompiles the stage1 compiler, you may need to work around this, by choosing BOOT_CFLAGS to avoid the parts ! of the stage1 compiler that were miscompiled, or by using ‘make ! bootstrap4’ to increase the number of stages of bootstrap. ! !

BOOT_CFLAGS does not apply to bootstrapped target libraries. Since these are always compiled with the compiler currently being bootstrapped, you can use CFLAGS_FOR_TARGET to modify their ! compilation flags, as for non-bootstrapped target libraries. Again, if the native compiler miscompiles the stage1 compiler, you may need to work around this by avoiding non-working parts of the stage1 compiler. Use STAGE1_TFLAGS to this end. ! !

If you used the flag --enable-languages=... to restrict ! the compilers to be built, only those you've actually enabled will be built. This will of course only build those runtime libraries, for which the particular compiler has been built. Please note, ! that re-defining LANGUAGES when calling ‘make’ does not work anymore! ! !

If the comparison of stage2 and stage3 fails, this normally indicates that the stage2 compiler has compiled GCC incorrectly, and is therefore a potentially serious bug which you should investigate and report. (On a few systems, meaningful comparison of object files is impossible; they always appear “different”. If you encounter this problem, you will ! need to disable comparison in the Makefile.) ! !

If you do not want to bootstrap your compiler, you can configure with ! --disable-bootstrap. In particular cases, you may want to bootstrap your compiler even if the target system is not the same as the one you are building on: for example, you could build a powerpc-unknown-linux-gnu toolchain on a powerpc64-unknown-linux-gnu host. In this case, pass ! --enable-bootstrap to the configure script. ! !

BUILD_CONFIG can be used to bring in additional customization ! to the build. It can be set to a whitespace-separated list of names. ! For each such NAME, top-level config/NAME.mk will ! be included by the top-level Makefile, bringing in any settings it contains. The default BUILD_CONFIG can be set using the ! configure option --with-build-config=NAME.... Some examples of supported build configurations are: ! !

!
‘bootstrap-O1’
Removes any -O-started option from BOOT_CFLAGS, and adds ! -O1 to it. ‘BUILD_CONFIG=bootstrap-O1’ is equivalent to ! ‘BOOT_CFLAGS='-g -O1'’. ! !
‘bootstrap-O3’
Analogous to bootstrap-O1. ! !
‘bootstrap-lto’
Enables Link-Time Optimization for host tools during bootstrapping. ! ‘BUILD_CONFIG=bootstrap-lto’ is equivalent to adding ! -flto to ‘BOOT_CFLAGS’. ! !
‘bootstrap-debug’
Verifies that the compiler generates the same executable code, whether or not it is asked to emit debug information. To this end, this option builds stage2 host programs without debug information, and uses ! contrib/compare-debug to compare them with the stripped stage3 object files. If BOOT_CFLAGS is overridden so as to not enable ! debug information, stage2 will have it, and stage3 won't. This option is enabled by default when GCC bootstrapping is enabled, if strip can turn object files compiled with and without debug info into identical object files. In addition to better test coverage, this option makes default bootstraps faster and leaner. ! !
‘bootstrap-debug-big’
Rather than comparing stripped object files, as in bootstrap-debug, this option saves internal compiler dumps during stage2 and stage3 and compares them as well, which helps catch additional potential problems, but at a great cost in terms of disk ! space. It can be specified in addition to ‘bootstrap-debug’. ! !
‘bootstrap-debug-lean’
This option saves disk space compared with bootstrap-debug-big, but at the expense of some recompilation. Instead of saving the dumps of stage2 and stage3 until the final compare, it uses ! -fcompare-debug to generate, compare and remove the dumps during stage3, repeating the compilation that already took place in stage2, whose dumps were not saved. ! !
‘bootstrap-debug-lib’
This option tests executable code invariance over debug information generation on target libraries, just like bootstrap-debug-lean tests it on host programs. It builds stage3 libraries with ! -fcompare-debug, and it can be used along with any of the bootstrap-debug options above. ! !

There aren't -lean or -big counterparts to this option because most libraries are only build in stage3, so bootstrap compares would not get significant coverage. Moreover, the few libraries built ! in stage2 are used in stage3 host programs, so we wouldn't want to compile stage2 libraries with different options for comparison purposes. ! !

‘bootstrap-debug-ckovw’
Arranges for error messages to be issued if the compiler built on any ! stage is run without the option -fcompare-debug. This is ! useful to verify the full -fcompare-debug testing coverage. It must be used along with bootstrap-debug-lean and bootstrap-debug-lib. ! !
‘bootstrap-time’
Arranges for the run time of each program started by the GCC driver, ! built in any stage, to be logged to time.log, in the top level of the build tree. !
! !

Building a cross compiler

When building a cross compiler, it is not generally possible to do a 3-stage bootstrap of the compiler. This makes for an interesting problem as parts of GCC can only be built with GCC. ! !

To build a cross compiler, we recommend first building and installing a native compiler. You can then use the native GCC compiler to build the cross compiler. The installed native compiler needs to be GCC version 2.95 or later. ! !

If the cross compiler is to be built with support for the Java programming language and the ability to compile .java source files is desired, the installed native compiler used to build the cross compiler needs to be the same GCC version as the cross compiler. In addition the cross compiler needs to be configured with ! --with-ecj-jar=.... ! !

Assuming you have already installed a native copy of GCC and configured ! your cross compiler, issue the command make, which performs the following steps: !

!

Note that if an error occurs in any step the make process will exit. !

If you are not building GNU binutils in the same source tree as GCC, you will need a cross-assembler and cross-linker installed before configuring GCC. Put them in the directory ! prefix/target/bin. Here is a table of the tools you should put in this directory: ! !

!
as
This should be the cross-assembler. ! !
ld
This should be the cross-linker. ! !
ar
This should be the cross-archiver: a program which can manipulate ! archive files (linker libraries) in the target machine's format. ! !
ranlib
This should be a program to construct a symbol table in an archive file.
!

The installation of GCC will find these programs in that directory, and copy or link them to the proper place to for the cross-compiler to find them when run later. ! !

The easiest way to provide these files is to build the Binutils package. ! Configure it with the same --host and --target options that you use for configuring GCC, then build and install them. They install their executables automatically into the proper directory. Alas, they do not support all the targets that GCC supports. ! !

If you are not building a C library in the same source tree as GCC, you should also provide the target libraries and headers before configuring GCC, specifying the directories with ! --with-sysroot or --with-headers and ! --with-libs. Many targets also require “start files” such ! as crt0.o and ! crtn.o which are linked into each executable. There may be several ! alternatives for crt0.o, for use with profiling or other ! compilation options. Check your target's definition of STARTFILE_SPEC to find out what start files it uses. ! !

Building in parallel

GNU Make 3.80 and above, which is necessary to build GCC, support ! building in parallel. To activate this, you can use ‘make -j 2’ ! instead of ‘make’. You can also specify a bigger number, and in most cases using a value greater than the number of processors in your machine will result in fewer and shorter I/O latency hits, thus improving overall throughput; this is especially true for slow drives and network filesystems. ! !

Building the Ada compiler

In order to build GNAT, the Ada compiler, you need a working GNAT ! compiler (GCC version 4.0 or later). ! This includes GNAT tools such as gnatmake and ! gnatlink, since the Ada front end is written in Ada and uses some GNAT-specific extensions. ! !

In order to build a cross compiler, it is suggested to install the new compiler as native first, and then use it to build the cross compiler. ! !

configure does not test whether the GNAT installation works and has a sufficiently recent version; if too old a GNAT version is ! installed, the build will fail unless --enable-languages is used to disable building the Ada front end. ! !

ADA_INCLUDE_PATH and ADA_OBJECT_PATH environment variables must not be set when building the Ada compiler, the Ada tools, or the Ada runtime libraries. You can check that your build environment is clean ! by verifying that ‘gnatls -v’ lists only one explicit path in each section. ! !

Building with profile feedback

It is possible to use profile feedback to optimize the compiler itself. This should result in a faster compiler binary. Experiments done on x86 using gcc 3.3 showed approximately 7 percent speedup on compiling C programs. To bootstrap the compiler with profile feedback, use make profiledbootstrap. ! !

When ‘make profiledbootstrap’ is run, it will first build a stage1 compiler. This compiler is used to build a stageprofile compiler instrumented to collect execution counts of instruction and branch ! probabilities. Then runtime libraries are compiled with profile collected. Finally a stagefeedback compiler is built using the information collected. ! !

Unlike standard bootstrap, several additional restrictions apply. The ! compiler used to build stage1 needs to support a 64-bit integral type. It is recommended to only use GCC for this. Also parallel make is currently not supported since collisions in profile collecting may occur. -

Installing GCC: Configuration

- - Like most GNU software, GCC must be configured before it can be built. - This document describes the recommended configuration procedure - for both native and cross targets. !

We use srcdir to refer to the toplevel source directory for ! GCC; we use objdir to refer to the toplevel build/object directory. -

If you obtained the sources via SVN, srcdir must refer to the top - gcc directory, the one where the MAINTAINERS file can be - found, and not its gcc subdirectory, otherwise the build will fail. !

If either srcdir or objdir is located on an automounted NFS ! file system, the shell's built-in pwd command will return temporary pathnames. Using these can lead to various sorts of build ! problems. To avoid this issue, set the PWDCMD environment ! variable to an automounter-aware pwd command, e.g., ! pawd or ‘amq -w’, during the configuration and build phases. ! !

First, we highly recommend that GCC be built into a separate directory from the sources which does not reside within the source tree. This is how we generally build GCC; building ! where srcdir == objdir should still work, but doesn't get extensive testing; building where objdir is a subdirectory of srcdir is unsupported. ! !

If you have previously built GCC in the same directory for a ! different target machine, do ‘make distclean’ to delete all files ! that might be invalid. One of the files this deletes is Makefile; ! if ‘make distclean’ complains that Makefile does not exist ! or issues a message like “don't know how to make distclean” it probably means that the directory is already suitably clean. However, with the recommended method of building in a separate objdir, you should simply use a different objdir for each target. ! !

Second, when configuring a native system, either cc or ! gcc must be in your path or you must set CC in your environment before running configure. Otherwise the configuration scripts may fail. !

To configure GCC: ! 

     % mkdir objdir
!      % cd objdir
!      % srcdir/configure [options] [target]
!
!

Distributor options

If you will be distributing binary versions of GCC, with modifications to the source code, you should use the options described in this section to make clear that your version contains modifications. ! !

!
--with-pkgversion=version
Specify a string that identifies your package. You may wish to include a build number or build date. This version string will be ! included in the output of gcc --version. This suffix does ! not replace the default version string, only the ‘GCC’ part. ! !

The default value is ‘GCC’. ! !

--with-bugurl=url
Specify the URL that users should visit if they wish to report a bug. You are of course welcome to forward bugs reported to you to the FSF, if you determine that they are not bugs in your modifications. !

The default value refers to the FSF's GCC bug tracker. ! !

Options specification

Use options to override several configure time options for ! GCC. A list of supported options follows; ‘configure ! --help’ may list other options, but those not listed below may not work and should not normally be used. ! !

Note that each --enable option has a corresponding ! --disable option and that each --with option has a ! corresponding --without option. ! !

!
--prefix=dirname
Specify the toplevel installation directory. This is the recommended way to install the tools into a directory other than the default. The toplevel installation directory defaults to ! /usr/local. ! !

We highly recommend against dirname being the same or a subdirectory of objdir or vice versa. If specifying a directory ! beneath a user's home directory tree, some shells will not expand ! dirname correctly if it contains the ‘~’ metacharacter; use ! $HOME instead. ! !

The following standard autoconf options are supported. Normally you should not need to use these options. !

!
--exec-prefix=dirname
Specify the toplevel installation directory for architecture-dependent files. The default is prefix. ! !
--bindir=dirname
Specify the installation directory for the executables called by users ! (such as gcc and g++). The default is ! exec-prefix/bin. ! !
--libdir=dirname
Specify the installation directory for object code libraries and ! internal data files of GCC. The default is exec-prefix/lib. ! !
--libexecdir=dirname
Specify the installation directory for internal executables of GCC. ! The default is exec-prefix/libexec. ! !
--with-slibdir=dirname
Specify the installation directory for the shared libgcc library. The default is libdir. ! !
--datarootdir=dirname
Specify the root of the directory tree for read-only architecture-independent ! data files referenced by GCC. The default is prefix/share. ! !
--infodir=dirname
Specify the installation directory for documentation in info format. ! The default is datarootdir/info. ! !
--datadir=dirname
Specify the installation directory for some architecture-independent data files referenced by GCC. The default is datarootdir. ! !
--docdir=dirname
Specify the installation directory for documentation files (other ! than Info) for GCC. The default is datarootdir/doc. ! !
--htmldir=dirname
Specify the installation directory for HTML documentation files. The default is docdir. ! !
--pdfdir=dirname
Specify the installation directory for PDF documentation files. The default is docdir. ! !
--mandir=dirname
Specify the installation directory for manual pages. The default is ! datarootdir/man. (Note that the manual pages are only extracts from the full GCC manuals, which are provided in Texinfo format. The manpages are derived by an automatic conversion process from parts of the full manual.) ! !
--with-gxx-include-dir=dirname
Specify the installation directory for G++ header files. The default depends on other configuration options, and differs between cross and native configurations. ! !
--with-specs=specs
Specify additional command line driver SPECS. This can be useful if you need to turn on a non-standard feature by ! default without modifying the compiler's source code, for instance ! --with-specs=%{!fcommon:%{!fno-common:-fno-common}}. See “Spec Files” in the main manual !
! !
--program-prefix=prefix
GCC supports some transformations of the names of its programs when installing them. This option prepends prefix to the names of programs to install in bindir (see above). For example, specifying ! --program-prefix=foo- would result in ‘gcc’ ! being installed as /usr/local/bin/foo-gcc. ! !
--program-suffix=suffix
Appends suffix to the names of programs to install in bindir ! (see above). For example, specifying --program-suffix=-3.1 ! would result in ‘gcc’ being installed as ! /usr/local/bin/gcc-3.1. ! !
--program-transform-name=pattern
Applies the ‘sed’ script pattern to be applied to the names of programs to install in bindir (see above). pattern has to ! consist of one or more basic ‘sed’ editing commands, separated by ! semicolons. For example, if you want the ‘gcc’ program name to be ! transformed to the installed program /usr/local/bin/myowngcc and ! the ‘g++’ program name to be transformed to ! /usr/local/bin/gspecial++ without changing other program names, you could use the pattern ! --program-transform-name='s/^gcc$/myowngcc/; s/^g++$/gspecial++/' to achieve this effect. ! !

All three options can be combined and used together, resulting in more complex conversion patterns. As a basic rule, prefix (and suffix) are prepended (appended) before further transformations can happen with a special transformation script pattern. ! !

As currently implemented, this option only takes effect for native ! builds; cross compiler binaries' names are not transformed even when a transformation is explicitly asked for by one of these options. ! !

For native builds, some of the installed programs are also installed with the target alias in front of their name, as in ! ‘i686-pc-linux-gnu-gcc’. All of the above transformations happen before the target alias is prepended to the name—so, specifying ! --program-prefix=foo- and program-suffix=-3.1, the resulting binary would be installed as ! /usr/local/bin/i686-pc-linux-gnu-foo-gcc-3.1. ! !

As a last shortcoming, none of the installed Ada programs are transformed yet, which will be fixed in some time. ! !

--with-local-prefix=dirname
Specify the installation directory for local include files. The default is ! /usr/local. Specify this option if you want the compiler to ! search directory dirname/include for locally installed ! header files instead of /usr/local/include. ! !

You should specify --with-local-prefix only if your ! site has a different convention (not /usr/local) for where to put site-specific files. ! !

The default value for --with-local-prefix is /usr/local ! regardless of the value of --prefix. Specifying ! --prefix has no effect on which directory GCC searches for local header files. This may seem counterintuitive, but actually it is logical. ! !

The purpose of --prefix is to specify where to install ! GCC. The local header files in /usr/local/include—if you put any in that directory—are not part of GCC. They are part of other programs—perhaps many others. (GCC installs its own header files in ! another directory which is based on the --prefix value.) ! !

Both the local-prefix include directory and the GCC-prefix include ! directory are part of GCC's “system include” directories. Although these two directories are not fixed, they need to be searched in the proper order for the correct processing of the include_next directive. The local-prefix include directory is searched before the GCC-prefix include directory. Another characteristic of system include directories is that pedantic warnings are turned off for headers in these directories. ! !

Some autoconf macros add -I directory options to the compiler command line, to ensure that directories containing installed ! packages' headers are searched. When directory is one of GCC's system include directories, GCC will ignore the option so that system directories continue to be processed in the correct order. This may result in a search order different from what was specified but the directory will still be searched. ! !

GCC automatically searches for ordinary libraries using ! GCC_EXEC_PREFIX. Thus, when the same installation prefix is used for both GCC and packages, GCC will automatically search for both headers and libraries. This provides a configuration that is easy to use. GCC behaves in a manner similar to that when it is ! installed as a system compiler in /usr. ! !

Sites that need to install multiple versions of GCC may not want to use the above simple configuration. It is possible to use the ! --program-prefix, --program-suffix and ! --program-transform-name options to install multiple versions into a single directory, but it may be simpler to use different prefixes ! and the --with-local-prefix option to specify the location of the site-specific files for each version. It will then be necessary for users to specify explicitly the location of local site libraries ! (e.g., with LIBRARY_PATH). ! !

The same value can be used for both --with-local-prefix and ! --prefix provided it is not /usr. This can be used ! to avoid the default search of /usr/local/include. ! !

Do not specify /usr as the --with-local-prefix! ! The directory you use for --with-local-prefix must not ! contain any of the system's standard header files. If it did contain them, certain programs would be miscompiled (including GNU Emacs, on certain targets), because this would override and nullify the header ! file corrections made by the fixincludes script. ! !

Indications are that people who use this option use it based on mistaken ideas of what it is for. People use it as if it specified where to install part of GCC. Perhaps they make this assumption because installing GCC creates the directory. ! !

--with-native-system-header-dir=dirname
Specifies that dirname is the directory that contains native system ! header files, rather than /usr/include. This option is most useful if you are creating a compiler that should be isolated from the system as much as possible. It is most commonly used with the ! --with-sysroot option and will cause GCC to search dirname inside the system root specified by that option. ! !
--enable-shared[=package[,...]]
Build shared versions of libraries, if shared libraries are supported on the target platform. Unlike GCC 2.95.x and earlier, shared libraries are enabled by default on all platforms that support shared libraries. ! !

If a list of packages is given as an argument, build shared libraries only for the listed packages. For other packages, only static libraries will be built. Package names currently recognized in the GCC tree are ! ‘libgcc’ (also known as ‘gcc’), ‘libstdc++’ (not ! ‘libstdc++-v3’), ‘libffi’, ‘zlib’, ‘boehm-gc’, ! ‘ada’, ‘libada’, ‘libjava’, ‘libgo’, and ‘libobjc’. ! Note ‘libiberty’ does not support shared libraries at all. ! !

Use --disable-shared to build only static libraries. Note that ! --disable-shared does not accept a list of package names as ! argument, only --enable-shared does. ! !

--with-gnu-as
Specify that the compiler should assume that the assembler it finds is the GNU assembler. However, this does not modify the rules to find an assembler and will result in confusion if the assembler found is not actually the GNU assembler. (Confusion may also result if the compiler finds the GNU assembler but has not been ! configured with --with-gnu-as.) If you have more than one assembler installed on your system, you may want to use this option in ! connection with --with-as=pathname or ! --with-build-time-tools=pathname. ! !

The following systems are the only ones where it makes a difference whether you use the GNU assembler. On any other system, ! --with-gnu-as has no effect. ! !

    !
  • ‘hppa1.0-any-any’ !
  • ‘hppa1.1-any-any’ !
  • ‘sparc-sun-solaris2.any’ !
  • ‘sparc64-any-solaris2.any’ !
!
--with-as=pathname
Specify that the compiler should use the assembler pointed to by pathname, rather than the one found by the standard rules to find an assembler, which are: !
    !
  • Unless GCC is being built with a cross compiler, check the ! libexec/gcc/target/version directory. ! libexec defaults to exec-prefix/libexec; exec-prefix defaults to prefix, which ! defaults to /usr/local unless overridden by the ! --prefix=pathname switch described above. target ! is the target system triple, such as ‘sparc-sun-solaris2.7’, and version denotes the GCC version, such as 3.0. !
  • If the target system is the same that you are building on, check ! operating system specific directories (e.g. /usr/ccs/bin on Sun Solaris 2). !
  • Check in the PATH for a tool whose name is prefixed by the target system triple. !
  • Check in the PATH for a tool whose name is not prefixed by the target system triple, if the host and target system triple are the same (in other words, we use a host tool if it can be used for ! the target as well). !
!

You may want to use --with-as if no assembler is installed in the directories listed above, or if you have multiple assemblers installed and want to choose one that is not found by the above rules. ! !

--with-gnu-ld
Same as --with-gnu-as but for the linker. ! !
--with-ld=pathname
Same as --with-as but for the linker. ! !
--with-stabs
Specify that stabs debugging information should be used instead of whatever format the host normally uses. Normally GCC uses the same debug format as the host system. ! !

On MIPS based systems and on Alphas, you must specify whether you want GCC to create the normal ECOFF debugging format, or to use BSD-style stabs passed through the ECOFF symbol table. The normal ECOFF debug format cannot fully handle languages other than C. BSD stabs format can handle other languages, but it only works with the GNU debugger GDB. ! !

Normally, GCC uses the ECOFF debugging format by default; if you ! prefer BSD stabs, specify --with-stabs when you configure GCC. ! !

No matter which default you choose when you configure GCC, the user ! can use the -gcoff and -gstabs+ options to specify explicitly the debug format for a particular compilation. ! !

--with-stabs is meaningful on the ISC system on the 386, also, if ! --with-gas is used. It selects use of stabs debugging information embedded in COFF output. This kind of debugging information supports C++ well; ordinary COFF debugging information does not. ! !

--with-stabs is also meaningful on 386 systems running SVR4. It selects use of stabs debugging information embedded in ELF output. The C++ compiler currently (2.6.0) does not support the DWARF debugging information normally used on 386 SVR4 platforms; stabs provide a workable alternative. This requires gas and gdb, as the normal SVR4 tools can not generate or interpret stabs. ! !

--with-tls=dialect
Specify the default TLS dialect, for systems were there is a choice. For ARM targets, possible values for dialect are gnu or gnu2, which select between the original GNU dialect and the GNU TLS descriptor-based dialect. ! !
--enable-multiarch
Specify whether to enable or disable multiarch support. The default is to check for glibc start files in a multiarch location, and enable it if the files are found. The auto detection is enabled for native builds, ! and for cross builds configured with --with-sysroot, and without ! --with-native-system-header-dir. More documentation about multiarch can be found at http://wiki.debian.org/Multiarch. ! !
--disable-multilib
Specify that multiple target libraries to support different target variants, calling conventions, etc. should not be built. The default is to build a predefined set of them. ! !

Some targets provide finer-grained control over which multilibs are built ! (e.g., --disable-softfloat): !

!
arm-*-*
fpu, 26bit, underscore, interwork, biendian, nofmult. ! !
m68*-*-*
softfloat, m68881, m68000, m68020. ! !
mips*-*-*
single-float, biendian, softfloat. ! !
powerpc*-*-*, rs6000*-*-*
aix64, pthread, softfloat, powercpu, powerpccpu, powerpcos, biendian, sysv, aix. !
! !
--with-multilib-list=list
--without-multilib-list
Specify what multilibs to build. Currently only implemented for sh*-*-* and x86-64-*-linux*. ! !
!
sh*-*-*
list is a comma separated list of CPU names. These must be of the form sh* or m* (in which case they match the compiler option for that processor). The list should not contain any endian options - ! these are handled by --with-endian. ! !

If list is empty, then there will be no multilibs for extra processors. The multilib for the secondary endian remains enabled. ! !

As a special case, if an entry in the list starts with a ! ! (exclamation point), then it is added to the list of excluded multilibs. ! Entries of this sort should be compatible with ‘MULTILIB_EXCLUDES’ (once the leading ! has been stripped). ! !

If --with-multilib-list is not given, then a default set of ! multilibs is selected based on the value of --target. This is usually the complete set of libraries, but some targets imply a more specialized subset. ! !

Example 1: to configure a compiler for SH4A only, but supporting both endians, with little endian being the default: ! 

               --with-cpu=sh4a --with-endian=little,big --with-multilib-list=
!
!

Example 2: to configure a compiler for both SH4A and SH4AL-DSP, but with only little endian SH4AL: ! 

               --with-cpu=sh4a --with-endian=little,big \
!                --with-multilib-list=sh4al,!mb/m4al
!
!
x86-64-*-linux*
list is a comma separated list of m32, m64 and mx32 to enable 32-bit, 64-bit and x32 run-time libraries, respectively. If list is empty, then there will be no multilibs and only the default run-time library will be enabled. ! !

If --with-multilib-list is not given, then only 32-bit and ! 64-bit run-time libraries will be enabled.

!
--with-endian=endians
Specify what endians to use. Currently only implemented for sh*-*-*. ! !

endians may be one of the following: !

!
big
Use big endian exclusively. !
little
Use little endian exclusively. !
big,little
Use big endian by default. Provide a multilib for little endian. !
little,big
Use little endian by default. Provide a multilib for big endian.
!
--enable-threads
Specify that the target supports threads. This affects the Objective-C compiler and runtime ! library, and exception handling for other languages like C++ and Java. On some systems, this is the default. ! !

In general, the best (and, in many cases, the only known) threading model available will be configured for use. Beware that on some systems, GCC has not been taught what threading models are generally ! available for the system. In this case, --enable-threads is an ! alias for --enable-threads=single. ! !

--disable-threads
Specify that threading support should be disabled for the system. ! This is an alias for --enable-threads=single. ! !
--enable-threads=lib
Specify that lib is the thread support library. This affects the Objective-C compiler and runtime library, and exception handling for other languages like C++ and Java. The possibilities for lib are: ! !
!
aix
AIX thread support. !
dce
DCE thread support. !
lynx
LynxOS thread support. !
mipssde
MIPS SDE thread support. !
no
This is an alias for ‘single’. !
posix
Generic POSIX/Unix98 thread support. !
rtems
RTEMS thread support. !
single
Disable thread support, should work for all platforms. !
tpf
TPF thread support. !
vxworks
VxWorks thread support. !
win32
Microsoft Win32 API thread support.
!
--enable-tls
Specify that the target supports TLS (Thread Local Storage). Usually configure can correctly determine if TLS is supported. In cases where it guesses incorrectly, TLS can be explicitly enabled or disabled with ! --enable-tls or --disable-tls. This can happen if the assembler supports TLS but the C library does not, or if the assumptions made by the configure test are incorrect. ! !
--disable-tls
Specify that the target does not support TLS. ! This is an alias for --enable-tls=no. ! !
--with-cpu=cpu
--with-cpu-32=cpu
--with-cpu-64=cpu
Specify which cpu variant the compiler should generate code for by default. ! cpu will be used as the default value of the -mcpu= switch. This option is only supported on some targets, including ARM, i386, M68k, ! PowerPC, and SPARC. The --with-cpu-32 and ! --with-cpu-64 options specify separate default CPUs for 32-bit and 64-bit modes; these options are only supported for i386, x86-64 and PowerPC. ! !
--with-schedule=cpu
--with-arch=cpu
--with-arch-32=cpu
--with-arch-64=cpu
--with-tune=cpu
--with-tune-32=cpu
--with-tune-64=cpu
--with-abi=abi
--with-fpu=type
--with-float=type
These configure options provide default values for the -mschedule=, ! -march=, -mtune=, -mabi=, and -mfpu= ! options and for -mhard-float or -msoft-float. As with ! --with-cpu, which switches will be accepted and acceptable values of the arguments depend on the target. ! !
--with-mode=mode
Specify if the compiler should default to -marm or -mthumb. This option is only supported on ARM targets. ! !
--with-stack-offset=num
This option sets the default for the -mstack-offset=num option, and will thus generally also control the setting of this option for libraries. This option is only supported on Epiphany targets. ! !
--with-fpmath=isa
This options sets -mfpmath=sse by default and specifies the default ! ISA for floating-point arithmetics. You can select either ‘sse’ which ! enables -msse2 or ‘avx’ which enables -mavx by default. This option is only supported on i386 and x86-64 targets. ! !
--with-divide=type
Specify how the compiler should generate code for checking for ! division by zero. This option is only supported on the MIPS target. The possibilities for type are: !
!
traps
Division by zero checks use conditional traps (this is the default on ! systems that support conditional traps). !
breaks
Division by zero checks use the break instruction.
! ! !
--with-llsc
On MIPS targets, make -mllsc the default when no ! -mno-llsc option is passed. This is the default for Linux-based targets, as the kernel will emulate them if the ISA does not provide them. ! !
--without-llsc
On MIPS targets, make -mno-llsc the default when no ! -mllsc option is passed. ! !
--with-synci
On MIPS targets, make -msynci the default when no ! -mno-synci option is passed. ! !
--without-synci
On MIPS targets, make -mno-synci the default when no ! -msynci option is passed. This is the default. ! !
--with-mips-plt
On MIPS targets, make use of copy relocations and PLTs. These features are extensions to the traditional SVR4-based MIPS ABIs and require support from GNU binutils and the runtime C library. ! !
--enable-__cxa_atexit
Define if you want to use __cxa_atexit, rather than atexit, to ! register C++ destructors for local statics and global objects. This is essential for fully standards-compliant handling of destructors, but requires __cxa_atexit in libc. This option is currently only available on systems with GNU libc. When enabled, this will cause ! -fuse-cxa-atexit to be passed by default. ! !
--enable-gnu-indirect-function
Define if you want to enable the ifunc attribute. This option is currently only available on systems with GNU libc on certain targets. ! !
--enable-target-optspace
Specify that target ! libraries should be optimized for code space instead of code speed. This is the default for the m32r platform. ! !
--with-cpp-install-dir=dirname
Specify that the user visible cpp program should be installed ! in prefix/dirname/cpp, in addition to bindir. ! !
--enable-comdat
Enable COMDAT group support. This is primarily used to override the automatically detected value. ! !
--enable-initfini-array
Force the use of sections .init_array and .fini_array (instead of .init and .fini) for constructors and ! destructors. Option --disable-initfini-array has the opposite effect. If neither option is specified, the configure script will try to guess whether the .init_array and .fini_array sections are supported and, if they are, use them. ! !
--enable-maintainer-mode
The build rules that regenerate the Autoconf and Automake output files as ! well as the GCC master message catalog gcc.pot are normally disabled. This is because it can only be rebuilt if the complete source tree is present. If you have changed the sources and want to rebuild the ! catalog, configuring with --enable-maintainer-mode will enable this. Note that you need a recent version of the gettext tools to do so. ! !
--disable-bootstrap
For a native build, the default configuration is to perform ! a 3-stage bootstrap of the compiler when ‘make’ is invoked, testing that GCC can compile itself correctly. If you want to disable ! this process, you can configure with --disable-bootstrap. ! !
--enable-bootstrap
In special cases, you may want to perform a 3-stage build ! even if the target and host triplets are different. This is possible when the host can run code compiled for ! the target (e.g. host is i686-linux, target is i486-linux). Starting from GCC 4.2, to do this you have to configure explicitly ! with --enable-bootstrap. ! !
--enable-generated-files-in-srcdir
Neither the .c and .h files that are generated from Bison and flex nor the info manuals and man pages that are built from the .texi files are present in the SVN development tree. When building GCC from that development tree, or from one of our snapshots, those generated files are placed in your build directory, which allows for the source to be in a readonly directory. ! !

If you configure with --enable-generated-files-in-srcdir then those generated files will go into the source directory. This is mainly intended for generating release or prerelease tarballs of the GCC sources, since it is not a requirement that the users of source releases to have flex, Bison, or makeinfo. ! !

--enable-version-specific-runtime-libs
Specify that runtime libraries should be installed in the compiler specific ! subdirectory (libdir/gcc) rather than the usual places. In ! addition, ‘libstdc++’'s include files will be installed into libdir unless you overruled it by using ! --with-gxx-include-dir=dirname. Using this option is particularly useful if you intend to use several versions of GCC in ! parallel. This is currently supported by ‘libgfortran’, ! ‘libjava’, ‘libmudflap’, ‘libstdc++’, and ‘libobjc’. ! !
--enable-languages=lang1,lang2,...
Specify that only a particular subset of compilers and their runtime libraries should be built. For a list of valid values for langN you can issue the following command in the ! gcc directory of your GCC source tree:
! 
          grep language= */config-lang.in
!
!

Currently, you can use any of the following: all, ada, c, c++, fortran, ! go, java, objc, obj-c++. ! Building the Ada compiler has special requirements, see below. If you do not pass this flag, or specify the option all, then all ! default languages available in the gcc sub-tree will be configured. Ada, Go and Objective-C++ are not default languages; the rest are. ! !

--enable-stage1-languages=lang1,lang2,...
Specify that a particular subset of compilers and their runtime libraries should be built with the system C compiler during stage 1 of the bootstrap process, rather than only in later stages with the bootstrapped C compiler. The list of valid values is the same as for ! --enable-languages, and the option all will select all ! of the languages enabled by --enable-languages. This option is primarily useful for GCC development; for instance, when a development version of the compiler cannot bootstrap due to compiler bugs, or when one is debugging front ends other than the C front end. When this option is used, one can then build the target libraries for the ! specified languages with the stage-1 compiler by using make ! stage1-bubble all-target, or run the testsuite on the stage-1 compiler ! for the specified languages using make stage1-start check-gcc. ! !
--disable-libada
Specify that the run-time libraries and tools used by GNAT should not be built. This can be useful for debugging, or for compatibility with previous Ada build procedures, when it was required to explicitly ! do a ‘make -C gcc gnatlib_and_tools’. ! !
--disable-libssp
Specify that the run-time libraries for stack smashing protection should not be built. ! !
--disable-libquadmath
Specify that the GCC quad-precision math library should not be built. On some systems, the library is required to be linkable when building ! the Fortran front end, unless --disable-libquadmath-support is used. ! !
--disable-libquadmath-support
Specify that the Fortran front end and libgfortran do not add support for libquadmath on systems supporting it. ! !
--disable-libgomp
Specify that the run-time libraries used by GOMP should not be built. ! !
--with-dwarf2
Specify that the compiler should use DWARF 2 debugging information as the default. ! !
--enable-targets=all
--enable-targets=target_list
Some GCC targets, e.g. powerpc64-linux, build bi-arch compilers. These are compilers that are able to generate either 64-bit or 32-bit ! code. Typically, the corresponding 32-bit target, e.g. powerpc-linux for powerpc64-linux, only generates 32-bit code. This option enables the 32-bit target to be a bi-arch compiler, which is useful when you want a bi-arch compiler that defaults to 32-bit, and ! you are building a bi-arch or multi-arch binutils in a combined tree. On mips-linux, this will build a tri-arch compiler (ABI o32/n32/64), ! defaulted to o32. Currently, this option only affects sparc-linux, powerpc-linux, x86-linux, mips-linux and s390-linux. ! !
--enable-secureplt
This option enables -msecure-plt by default for powerpc-linux. See “RS/6000 and PowerPC Options” in the main manual ! !
--enable-cld
This option enables -mcld by default for 32-bit x86 targets. See “i386 and x86-64 Options” in the main manual ! !
--enable-win32-registry
--enable-win32-registry=key
--disable-win32-registry
The --enable-win32-registry option enables Microsoft Windows-hosted GCC to look up installations paths in the registry using the following key: ! 
          HKEY_LOCAL_MACHINE\SOFTWARE\Free Software Foundation\key
!
!

key defaults to GCC version number, and can be overridden by the ! --enable-win32-registry=key option. Vendors and distributors who use custom installers are encouraged to provide a different key, perhaps one comprised of vendor name and GCC version number, to avoid conflict with existing installations. This feature is enabled ! by default, and can be disabled by --disable-win32-registry option. This option has no effect on the other hosts. ! !

--nfp
Specify that the machine does not have a floating point unit. This ! option only applies to ‘m68k-sun-sunosn’. On any other ! system, --nfp has no effect. ! !
--enable-werror
--disable-werror
--enable-werror=yes
--enable-werror=no
When you specify this option, it controls whether certain files in the ! compiler are built with -Werror in bootstrap stage2 and later. ! If you don't specify it, -Werror is turned on for the main development trunk. However it defaults to off for release branches and ! final releases. The specific files which get -Werror are controlled by the Makefiles. ! !
--enable-checking
--enable-checking=list
When you specify this option, the compiler is built to perform internal consistency checks of the requested complexity. This does not change the generated code, but adds error checking within the compiler. This will slow down the compiler and may only work properly if you are building ! the compiler with GCC. This is ‘yes’ by default when building ! from SVN or snapshots, but ‘release’ for releases. The default ! for building the stage1 compiler is ‘yes’. More control over the checks may be had by specifying list. The categories of ! checks available are ‘yes’ (most common checks ! ‘assert,misc,tree,gc,rtlflag,runtime’), ‘no’ (no checks at ! all), ‘all’ (all but ‘valgrind’), ‘release’ (cheapest ! checks ‘assert,runtime’) or ‘none’ (same as ‘no’). ! Individual checks can be enabled with these flags ‘assert’, ! ‘df’, ‘fold’, ‘gc’, ‘gcac’ ‘misc’, ‘rtl’, ! ‘rtlflag’, ‘runtime’, ‘tree’, and ‘valgrind’. ! !

The ‘valgrind’ check requires the external valgrind simulator, available from http://valgrind.org/. The ! ‘df’, ‘rtl’, ‘gcac’ and ‘valgrind’ checks are very expensive. ! To disable all checking, ‘--disable-checking’ or ! ‘--enable-checking=none’ must be explicitly requested. Disabling assertions will make the compiler and runtime slightly faster but increase the risk of undetected internal errors causing wrong code to be generated. ! !

--disable-stage1-checking
--enable-stage1-checking
--enable-stage1-checking=list
If no --enable-checking option is specified the stage1 ! compiler will be built with ‘yes’ checking enabled, otherwise the stage1 checking flags are the same as specified by ! --enable-checking. To build the stage1 compiler with ! different checking options use --enable-stage1-checking. ! The list of checking options is the same as for --enable-checking. If your system is too slow or too small to bootstrap a released compiler ! with checking for stage1 enabled, you can use ‘--disable-stage1-checking’ to disable checking for the stage1 compiler. ! !
--enable-coverage
--enable-coverage=level
With this option, the compiler is built to collect self coverage information, every time it is run. This is for internal development purposes, and only works when the compiler is being built with gcc. The level argument controls whether the compiler is built optimized or ! not, values are ‘opt’ and ‘noopt’. For coverage analysis you want to disable optimization, for performance analysis you want to enable optimization. When coverage is enabled, the default level is without optimization. ! !
--enable-gather-detailed-mem-stats
When this option is specified more detailed information on memory allocation is gathered. This information is printed when using ! -fmem-report. ! !
--enable-nls
--disable-nls
The --enable-nls option enables Native Language Support (NLS), which lets GCC output diagnostics in languages other than American English. Native Language Support is enabled by default if not doing a ! canadian cross build. The --disable-nls option disables NLS. ! !
--with-included-gettext
If NLS is enabled, the --with-included-gettext option causes the build ! procedure to prefer its copy of GNU gettext. ! !
--with-catgets
If NLS is enabled, and if the host lacks gettext but has the inferior catgets interface, the GCC build procedure normally ! ignores catgets and instead uses GCC's copy of the GNU ! gettext library. The --with-catgets option causes the ! build procedure to use the host's catgets in this situation. ! !
--with-libiconv-prefix=dir
Search for libiconv header files in dir/include and ! libiconv library files in dir/lib. ! !
--enable-obsolete
Enable configuration for an obsoleted system. If you attempt to configure GCC for a system (build, host, or target) which has been obsoleted, and you do not specify this flag, configure will halt with an error message. ! !

All support for systems which have been obsoleted in one release of GCC is removed entirely in the next major release, unless someone steps forward to maintain the port. ! !

--enable-decimal-float
--enable-decimal-float=yes
--enable-decimal-float=no
--enable-decimal-float=bid
--enable-decimal-float=dpd
--disable-decimal-float
Enable (or disable) support for the C decimal floating point extension that is in the IEEE 754-2008 standard. This is enabled by default only on PowerPC, i386, and x86_64 GNU/Linux systems. Other systems may also support it, but require the user to specifically enable it. You can optionally control which decimal floating point format is used (either ! ‘bid’ or ‘dpd’). The ‘bid’ (binary integer decimal) ! format is default on i386 and x86_64 systems, and the ‘dpd’ (densely packed decimal) format is default on PowerPC systems. ! !
--enable-fixed-point
--disable-fixed-point
Enable (or disable) support for C fixed-point arithmetic. This option is enabled by default for some targets (such as MIPS) which have hardware-support for fixed-point operations. On other targets, you may enable this option manually. ! !
--with-long-double-128
Specify if long double type should be 128-bit by default on selected GNU/Linux architectures. If using --without-long-double-128, ! long double will be by default 64-bit, the same as double type. When neither of these configure options are used, the default will be 128-bit long double when built against GNU C Library 2.4 and later, 64-bit long double otherwise. ! !
--with-gmp=pathname
--with-gmp-include=pathname
--with-gmp-lib=pathname
--with-mpfr=pathname
--with-mpfr-include=pathname
--with-mpfr-lib=pathname
--with-mpc=pathname
--with-mpc-include=pathname
--with-mpc-lib=pathname
If you want to build GCC but do not have the GMP library, the MPFR library and/or the MPC library installed in a standard location and do not have their sources present in the GCC source tree then you can explicitly specify the directory where they are installed ! (‘--with-gmp=gmpinstalldir’, ! ‘--with-mpfr=mpfrinstalldir’, ! ‘--with-mpc=mpcinstalldir’). The ! --with-gmp=gmpinstalldir option is shorthand for ! --with-gmp-lib=gmpinstalldir/lib and ! --with-gmp-include=gmpinstalldir/include. Likewise the ! --with-mpfr=mpfrinstalldir option is shorthand for ! --with-mpfr-lib=mpfrinstalldir/lib and ! --with-mpfr-include=mpfrinstalldir/include, also the ! --with-mpc=mpcinstalldir option is shorthand for ! --with-mpc-lib=mpcinstalldir/lib and ! --with-mpc-include=mpcinstalldir/include. If these shorthand assumptions are not correct, you can use the explicit include and lib options directly. You might also need to ensure the shared libraries can be found by the dynamic linker when building and using GCC, for example by setting the runtime shared library path ! variable (LD_LIBRARY_PATH on GNU/Linux and Solaris systems). ! !

These flags are applicable to the host platform only. When building a cross compiler, they will not be used to configure target libraries. ! !

--with-isl=pathname
--with-isl-include=pathname
--with-isl-lib=pathname
--with-cloog=pathname
--with-cloog-include=pathname
--with-cloog-lib=pathname
If you do not have ISL and the CLooG libraries installed in a standard location and you want to build GCC, you can explicitly specify the directory where they are installed ! (‘--with-isl=islinstalldir’, ! ‘--with-cloog=clooginstalldir’). The ! --with-isl=islinstalldir option is shorthand for ! --with-isl-lib=islinstalldir/lib and ! --with-isl-include=islinstalldir/include. Likewise the ! --with-cloog=clooginstalldir option is shorthand for ! --with-cloog-lib=clooginstalldir/lib and ! --with-cloog-include=clooginstalldir/include. If these shorthand assumptions are not correct, you can use the explicit include and lib options directly. ! !

These flags are applicable to the host platform only. When building a cross compiler, they will not be used to configure target libraries. ! !

--with-host-libstdcxx=linker-args
If you are linking with a static copy of PPL, you can use this option to specify how the linker should find the standard C++ library used internally by PPL. Typical values of linker-args might be ! ‘-lstdc++’ or ‘-Wl,-Bstatic,-lstdc++,-Bdynamic -lm’. If you are linking with a shared copy of PPL, you probably do not need this option; shared library dependencies will cause the linker to search for the standard C++ library automatically. ! !
--with-stage1-ldflags=flags
This option may be used to set linker flags to be used when linking stage 1 of GCC. These are also used when linking GCC if configured with ! --disable-bootstrap. By default no special flags are used. ! !
--with-stage1-libs=libs
This option may be used to set libraries to be used when linking stage 1 of GCC. These are also used when linking GCC if configured with ! --disable-bootstrap. The default is the argument to ! --with-host-libstdcxx, if specified. ! !
--with-boot-ldflags=flags
This option may be used to set linker flags to be used when linking stage 2 and later when bootstrapping GCC. If neither –with-boot-libs nor –with-host-libstdcxx is set to a value, then the default is ! ‘-static-libstdc++ -static-libgcc’. ! !
--with-boot-libs=libs
This option may be used to set libraries to be used when linking stage 2 and later when bootstrapping GCC. The default is the argument to ! --with-host-libstdcxx, if specified. ! !
--with-debug-prefix-map=map
Convert source directory names using -fdebug-prefix-map when building runtime libraries. ‘map’ is a space-separated ! list of maps of the form ‘old=new’. ! !
--enable-linker-build-id
Tells GCC to pass --build-id option to the linker for all final ! links (links performed without the -r or --relocatable option), if the linker supports it. If you specify ! --enable-linker-build-id, but your linker does not ! support --build-id option, a warning is issued and the ! --enable-linker-build-id option is ignored. The default is off. ! !
--with-linker-hash-style=choice
Tells GCC to pass --hash-style=choice option to the linker for all final links. choice can be one of ! ‘sysv’, ‘gnu’, and ‘both’ where ‘sysv’ is the default. ! !
--enable-gnu-unique-object
--disable-gnu-unique-object
Tells GCC to use the gnu_unique_object relocation for C++ template static data members and inline function local statics. Enabled by default for a native toolchain with an assembler that accepts it and GLIBC 2.11 or above, otherwise disabled. ! !
--enable-lto
--disable-lto
Enable support for link-time optimization (LTO). This is enabled by ! default, and may be disabled using --disable-lto. ! !
--with-plugin-ld=pathname
Enable an alternate linker to be used at link-time optimization (LTO) ! link time when -fuse-linker-plugin is enabled. This linker should have plugin support such as gold starting with ! version 2.20 or GNU ld starting with version 2.21. ! See -fuse-linker-plugin for details. ! !
--enable-canonical-system-headers
--disable-canonical-system-headers
Enable system header path canonicalization for libcpp. This can produce shorter header file paths in diagnostics and dependency output files, but these changed header paths may conflict with some compilation environments. Enabled by default, and may be disabled using ! --disable-canonical-system-headers.
!

Cross-Compiler-Specific Options

!

The following options only apply to building cross compilers. ! !

!
--with-sysroot
--with-sysroot=dir
Tells GCC to consider dir as the root of a tree that contains ! (a subset of) the root filesystem of the target operating system. Target system headers, libraries and run-time object files will be searched for in there. More specifically, this acts as if ! --sysroot=dir was added to the default options of the built compiler. The specified directory is not copied into the ! install tree, unlike the options --with-headers and ! --with-libs that this option obsoletes. The default value, ! in case --with-sysroot is not given an argument, is ! ${gcc_tooldir}/sys-root. If the specified directory is a ! subdirectory of ${exec_prefix}, then it will be found relative to the GCC binaries if the installation tree is moved. ! !

This option affects the system root for the compiler used to build target libraries (which runs on the build system) and the compiler newly installed with make install; it does not affect the compiler which is used to build GCC itself. ! !

If you specify the --with-native-system-header-dir=dirname option then the compiler will search that directory within dirname for ! native system headers rather than the default /usr/include. ! !

--with-build-sysroot
--with-build-sysroot=dir
Tells GCC to consider dir as the system root (see ! --with-sysroot) while building target libraries, instead of ! the directory specified with --with-sysroot. This option is ! only useful when you are already using --with-sysroot. You ! can use --with-build-sysroot when you are configuring with ! --prefix set to a directory that is different from the one in which you are installing GCC and your target libraries. ! !

This option affects the system root for the compiler used to build target libraries (which runs on the build system); it does not affect the compiler which is used to build GCC itself. ! !

If you specify the --with-native-system-header-dir=dirname option then the compiler will search that directory within dirname for ! native system headers rather than the default /usr/include. ! !

--with-headers
--with-headers=dir
Deprecated in favor of --with-sysroot. ! Specifies that target headers are available when building a cross compiler. The dir argument specifies a directory which has the target include ! files. These include files will be copied into the gcc install ! directory. This option with the dir argument is required when ! building a cross compiler, if prefix/target/sys-include ! doesn't pre-exist. If prefix/target/sys-include does ! pre-exist, the dir argument may be omitted. fixincludes will be run on these files to make them compatible with GCC. ! !
--without-headers
Tells GCC not use any target headers from a libc when building a cross compiler. When crossing to GNU/Linux, you need the headers so GCC can build the exception handling for libgcc. ! !
--with-libs
--with-libs="dir1 dir2 ... dirN"
Deprecated in favor of --with-sysroot. Specifies a list of directories which contain the target runtime ! libraries. These libraries will be copied into the gcc install directory. If the directory list is omitted, this option has no effect. ! !
--with-newlib
Specifies that ‘newlib’ is being used as the target C library. This causes __eprintf to be ! omitted from libgcc.a on the assumption that it will be provided by ! ‘newlib’. ! !
--with-avrlibc
Specifies that ‘AVR-Libc’ is being used as the target C library. This causes float support ! functions like __addsf3 to be omitted from libgcc.a on ! the assumption that it will be provided by libm.a. For more ! technical details, cf. PR54461. This option is only supported for the AVR target. It is not supported for RTEMS configurations, which currently use newlib. The option is supported since version 4.7.2 and is the default in 4.8.0 and newer. ! !
--with-build-time-tools=dir
Specifies where to find the set of target tools (assembler, linker, etc.) that will be used while building GCC itself. This option can be useful if the directory layouts are different between the system you are building GCC on, and the system where you will deploy it. ! !

For example, on an ‘ia64-hp-hpux’ system, you may have the GNU ! assembler and linker in /usr/bin, and the native tools in a different path, and build a toolchain that expects to find the ! native tools in /usr/bin. ! !

When you use this option, you should ensure that dir includes ! ar, as, ld, nm, ! ranlib and strip if necessary, and possibly ! objdump. Otherwise, GCC may use an inconsistent set of ! tools.

!

Java-Specific Options

The following option applies to the build of the Java front end. ! !

!
--disable-libgcj
Specify that the run-time libraries used by GCJ should not be built. This is useful in case you intend ! to use GCJ with some other run-time, or you're going to install it separately, or it just happens not to build on your particular machine. In general, if the Java front end is enabled, the GCJ ! libraries will be enabled too, unless they're known to not work on ! the target platform. If GCJ is enabled but ‘libgcj’ isn't built, you may need to port it; in this case, before modifying the top-level ! configure.in so that ‘libgcj’ is enabled by default on this platform, ! you may use --enable-libgcj to override the default. ! !
! !

The following options apply to building ‘libgcj’. !

General Options
!
!
--enable-java-maintainer-mode
By default the ‘libjava’ build will not attempt to compile the ! .java source files to .class. Instead, it will use the ! .class files from the source tree. If you use this option you ! must have executables named ecj1 and gjavah in your path for use by the build. You must use this option if you intend to ! modify any .java files in libjava. ! !
--with-java-home=dirname
This ‘libjava’ option overrides the default value of the ! ‘java.home’ system property. It is also used to set ! ‘sun.boot.class.path’ to dirname/lib/rt.jar. By ! default ‘java.home’ is set to prefix and ! ‘sun.boot.class.path’ to ! datadir/java/libgcj-version.jar. ! !
--with-ecj-jar=filename
This option can be used to specify the location of an external jar file containing the Eclipse Java compiler. A specially modified ! version of this compiler is used by gcj to parse ! .java source files. If this option is given, the ! ‘libjava’ build will create and install an ecj1 executable which uses this jar file at runtime. ! !

If this option is not given, but an ecj.jar file is found in ! the topmost source tree at configure time, then the ‘libgcj’ ! build will create and install ecj1, and will also install the ! discovered ecj.jar into a suitable place in the install tree. ! !

If ecj1 is not installed, then the user will have to supply one ! on his path in order for gcj to properly parse .java source files. A suitable jar is available from ftp://sourceware.org/pub/java/. ! !

--disable-getenv-properties
Don't set system properties from GCJ_PROPERTIES. ! !
--enable-hash-synchronization
Use a global hash table for monitor locks. Ordinarily, ! ‘libgcj’'s ‘configure’ script automatically makes the correct choice for this option for your platform. Only use this if you know you need the library to be configured differently. ! !
--enable-interpreter
Enable the Java interpreter. The interpreter is automatically enabled by default on all platforms that support it. This option is really only useful if you want to disable the interpreter ! (using --disable-interpreter). ! !
--disable-java-net
Disable java.net. This disables the native part of java.net only, using non-functional stubs for native method implementations. ! !
--disable-jvmpi
Disable JVMPI support. ! !
--disable-libgcj-bc
Disable BC ABI compilation of certain parts of libgcj. By default, ! some portions of libgcj are compiled with -findirect-dispatch ! and -fno-indirect-classes, allowing them to be overridden at run-time. ! !

If --disable-libgcj-bc is specified, libgcj is built without these options. This allows the compile-time linker to resolve dependencies when statically linking to libgcj. However it makes it impossible to override the affected portions of libgcj at run-time. ! !

--enable-reduced-reflection
Build most of libgcj with -freduced-reflection. This reduces the size of libgcj at the expense of not being able to do accurate reflection on the classes it contains. This option is safe if you know that code using libgcj will never use reflection on the standard runtime classes in libgcj (including using serialization, RMI or CORBA). ! !
--with-ecos
Enable runtime eCos target support. ! !
--without-libffi
Don't use ‘libffi’. This will disable the interpreter and JNI ! support as well, as these require ‘libffi’ to work. ! !
--enable-libgcj-debug
Enable runtime debugging code. ! !
--enable-libgcj-multifile
If specified, causes all .java source files to be ! compiled into .class files in one invocation of ! ‘gcj’. This can speed up build time, but is more resource-intensive. If this option is unspecified or ! disabled, ‘gcj’ is invoked once for each .java ! file to compile into a .class file. ! !
--with-libiconv-prefix=DIR
Search for libiconv in DIR/include and DIR/lib. ! !
--enable-sjlj-exceptions
Force use of the setjmp/longjmp-based scheme for exceptions. ! ‘configure’ ordinarily picks the correct value based on the platform. Only use this option if you are sure you need a different setting. ! !
--with-system-zlib
Use installed ‘zlib’ rather than that included with GCC. ! !
--with-win32-nlsapi=ansi, unicows or unicode
Indicates how MinGW ‘libgcj’ translates between UNICODE characters and the Win32 API. ! !
--enable-java-home
If enabled, this creates a JPackage compatible SDK environment during install. Note that if –enable-java-home is used, –with-arch-directory=ARCH must also be specified. ! !
--with-arch-directory=ARCH
Specifies the name to use for the jre/lib/ARCH directory in the SDK environment created when –enable-java-home is passed. Typical names for this directory include i386, amd64, ia64, etc. ! !
--with-os-directory=DIR
Specifies the OS directory for the SDK include directory. This is set to auto ! detect, and is typically 'linux'. ! !
--with-origin-name=NAME
Specifies the JPackage origin name. This defaults to the 'gcj' in java-1.5.0-gcj. ! !
--with-arch-suffix=SUFFIX
Specifies the suffix for the sdk directory. Defaults to the empty string. ! Examples include '.x86_64' in 'java-1.5.0-gcj-1.5.0.0.x86_64'. ! !
--with-jvm-root-dir=DIR
Specifies where to install the SDK. Default is $(prefix)/lib/jvm. ! !
--with-jvm-jar-dir=DIR
Specifies where to install jars. Default is $(prefix)/lib/jvm-exports. ! !
--with-python-dir=DIR
Specifies where to install the Python modules used for aot-compile. DIR should not include the prefix used in installation. For example, if the Python modules are to be installed in /usr/lib/python2.5/site-packages, then –with-python-dir=/lib/python2.5/site-packages should be passed. If this is not specified, then the Python modules are installed in $(prefix)/share/python. ! !
--enable-aot-compile-rpm
Adds aot-compile-rpm to the list of installed scripts. ! !
--enable-browser-plugin
Build the gcjwebplugin web browser plugin. ! !
--enable-static-libjava
Build static libraries in libjava. The default is to only build shared libraries. ! !
!
ansi
Use the single-byte char and the Win32 A functions natively, translating to and from UNICODE when using these functions. If unspecified, this is the default. ! !
unicows
Use the WCHAR and Win32 W functions natively. Adds ! -lunicows to libgcj.spec to link with ‘libunicows’. ! unicows.dll needs to be deployed on Microsoft Windows 9X machines ! running built executables. libunicows.a, an open-source ! import library around Microsoft's unicows.dll, is obtained from http://libunicows.sourceforge.net/, which also gives details ! on getting unicows.dll from Microsoft. ! !
unicode
Use the WCHAR and Win32 W functions natively. Does not ! add -lunicows to libgcj.spec. The built executables will ! only run on Microsoft Windows NT and above.
-
- -
AWT-Specific Options
- -
-
--with-x
Use the X Window System. - -
--enable-java-awt=PEER(S)
Specifies the AWT peer library or libraries to build alongside - ‘libgcj’. If this option is unspecified or disabled, AWT - will be non-functional. Current valid values are gtk and - xlib. Multiple libraries should be separated by a - comma (i.e. --enable-java-awt=gtk,xlib). - -
--enable-gtk-cairo
Build the cairo Graphics2D implementation on GTK. - -
--enable-java-gc=TYPE
Choose garbage collector. Defaults to boehm if unspecified. !
--disable-gtktest
Do not try to compile and run a test GTK+ program. !
--disable-glibtest
Do not try to compile and run a test GLIB program. !
--with-libart-prefix=PFX
Prefix where libart is installed (optional). !
--with-libart-exec-prefix=PFX
Exec prefix where libart is installed (optional). !
--disable-libarttest
Do not try to compile and run a test libart program. -
-
Overriding configure test results
-

Sometimes, it might be necessary to override the result of some - configure test, for example in order to ease porting to a new - system or work around a bug in a test. The toplevel configure - script provides three variables for this: -

-
build_configargs
The contents of this variable is passed to all build configure - scripts. -
host_configargs
The contents of this variable is passed to all host configure - scripts. -
target_configargs
The contents of this variable is passed to all target configure - scripts. -
-

In order to avoid shell and make quoting issues for complex - overrides, you can pass a setting for CONFIG_SITE and set - variables in the site file. -

Installing GCC

! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !

Like most GNU software, GCC must be configured before it can be built. ! This document describes the recommended configuration procedure ! for both native and cross targets. !

!

We use srcdir to refer to the toplevel source directory for ! GCC; we use objdir to refer to the toplevel build/object directory. !

!

If you obtained the sources via SVN, srcdir must refer to the top ! gcc directory, the one where the MAINTAINERS file can be ! found, and not its gcc subdirectory, otherwise the build will fail. !

!

If either srcdir or objdir is located on an automounted NFS ! file system, the shell’s built-in pwd command will return temporary pathnames. Using these can lead to various sorts of build ! problems. To avoid this issue, set the PWDCMD environment ! variable to an automounter-aware pwd command, e.g., ! pawd or ‘amq -w’, during the configuration and build phases. !

!

First, we highly recommend that GCC be built into a separate directory from the sources which does not reside within the source tree. This is how we generally build GCC; building ! where srcdir == objdir should still work, but doesn’t get extensive testing; building where objdir is a subdirectory of srcdir is unsupported. !

!

If you have previously built GCC in the same directory for a ! different target machine, do ‘make distclean’ to delete all files ! that might be invalid. One of the files this deletes is Makefile; ! if ‘make distclean’ complains that Makefile does not exist ! or issues a message like “don’t know how to make distclean” it probably means that the directory is already suitably clean. However, with the recommended method of building in a separate objdir, you should simply use a different objdir for each target. !

!

Second, when configuring a native system, either cc or ! gcc must be in your path or you must set CC in your environment before running configure. Otherwise the configuration scripts may fail. +

!

To configure GCC: !

!
! 
% mkdir objdir
! % cd objdir
! % srcdir/configure [options] [target]
!
! !

Distributor options

If you will be distributing binary versions of GCC, with modifications to the source code, you should use the options described in this section to make clear that your version contains modifications. !

!
!
--with-pkgversion=version
!

Specify a string that identifies your package. You may wish to include a build number or build date. This version string will be ! included in the output of gcc --version. This suffix does ! not replace the default version string, only the ‘GCC’ part. !

!

The default value is ‘GCC’. !

!
!
--with-bugurl=url
!

Specify the URL that users should visit if they wish to report a bug. You are of course welcome to forward bugs reported to you to the FSF, if you determine that they are not bugs in your modifications. +

+

The default value refers to the FSF’s GCC bug tracker. +

+
+
! !

Target specification

! ! ! !

Options specification

Use options to override several configure time options for ! GCC. A list of supported options follows; ‘configure ! --help’ may list other options, but those not listed below may not work and should not normally be used. !

!

Note that each --enable option has a corresponding ! --disable option and that each --with option has a ! corresponding --without option. !

!
!
--prefix=dirname
!

Specify the toplevel installation directory. This is the recommended way to install the tools into a directory other than the default. The toplevel installation directory defaults to ! /usr/local. !

!

We highly recommend against dirname being the same or a subdirectory of objdir or vice versa. If specifying a directory ! beneath a user’s home directory tree, some shells will not expand ! dirname correctly if it contains the ‘~’ metacharacter; use ! $HOME instead. !

!

The following standard autoconf options are supported. Normally you should not need to use these options. !

!
--exec-prefix=dirname
!

Specify the toplevel installation directory for architecture-dependent files. The default is prefix. !

!
!
--bindir=dirname
!

Specify the installation directory for the executables called by users ! (such as gcc and g++). The default is ! exec-prefix/bin. !

!
!
--libdir=dirname
!

Specify the installation directory for object code libraries and ! internal data files of GCC. The default is exec-prefix/lib. !

!
!
--libexecdir=dirname
!

Specify the installation directory for internal executables of GCC. ! The default is exec-prefix/libexec. !

!
!
--with-slibdir=dirname
!

Specify the installation directory for the shared libgcc library. The default is libdir. !

!
!
--datarootdir=dirname
!

Specify the root of the directory tree for read-only architecture-independent ! data files referenced by GCC. The default is prefix/share. !

!
!
--infodir=dirname
!

Specify the installation directory for documentation in info format. ! The default is datarootdir/info. !

!
!
--datadir=dirname
!

Specify the installation directory for some architecture-independent data files referenced by GCC. The default is datarootdir. !

!
!
--docdir=dirname
!

Specify the installation directory for documentation files (other ! than Info) for GCC. The default is datarootdir/doc. !

!
!
--htmldir=dirname
!

Specify the installation directory for HTML documentation files. The default is docdir. !

!
!
--pdfdir=dirname
!

Specify the installation directory for PDF documentation files. The default is docdir. !

!
!
--mandir=dirname
!

Specify the installation directory for manual pages. The default is ! datarootdir/man. (Note that the manual pages are only extracts from the full GCC manuals, which are provided in Texinfo format. The manpages are derived by an automatic conversion process from parts of the full manual.) !

!
!
--with-gxx-include-dir=dirname
!

Specify the installation directory for G++ header files. The default depends on other configuration options, and differs between cross and native configurations. !

!
!
--with-specs=specs
!

Specify additional command line driver SPECS. This can be useful if you need to turn on a non-standard feature by ! default without modifying the compiler’s source code, for instance ! --with-specs=%{!fcommon:%{!fno-common:-fno-common}}. See “Spec Files” in the main manual +

+
+
!
!
--program-prefix=prefix
!

GCC supports some transformations of the names of its programs when installing them. This option prepends prefix to the names of programs to install in bindir (see above). For example, specifying ! --program-prefix=foo- would result in ‘gcc’ ! being installed as /usr/local/bin/foo-gcc. !

!
!
--program-suffix=suffix
!

Appends suffix to the names of programs to install in bindir ! (see above). For example, specifying --program-suffix=-3.1 ! would result in ‘gcc’ being installed as ! /usr/local/bin/gcc-3.1. !

!
!
--program-transform-name=pattern
!

Applies the ‘sed’ script pattern to be applied to the names of programs to install in bindir (see above). pattern has to ! consist of one or more basic ‘sed’ editing commands, separated by ! semicolons. For example, if you want the ‘gcc’ program name to be ! transformed to the installed program /usr/local/bin/myowngcc and ! the ‘g++’ program name to be transformed to ! /usr/local/bin/gspecial++ without changing other program names, you could use the pattern ! --program-transform-name='s/^gcc$/myowngcc/; s/^g++$/gspecial++/' to achieve this effect. !

!

All three options can be combined and used together, resulting in more complex conversion patterns. As a basic rule, prefix (and suffix) are prepended (appended) before further transformations can happen with a special transformation script pattern. !

!

As currently implemented, this option only takes effect for native ! builds; cross compiler binaries’ names are not transformed even when a transformation is explicitly asked for by one of these options. !

!

For native builds, some of the installed programs are also installed with the target alias in front of their name, as in ! ‘i686-pc-linux-gnu-gcc’. All of the above transformations happen before the target alias is prepended to the name—so, specifying ! --program-prefix=foo- and program-suffix=-3.1, the resulting binary would be installed as ! /usr/local/bin/i686-pc-linux-gnu-foo-gcc-3.1. !

!

As a last shortcoming, none of the installed Ada programs are transformed yet, which will be fixed in some time. !

!
!
--with-local-prefix=dirname
!

Specify the installation directory for local include files. The default is ! /usr/local. Specify this option if you want the compiler to ! search directory dirname/include for locally installed ! header files instead of /usr/local/include. !

!

You should specify --with-local-prefix only if your ! site has a different convention (not /usr/local) for where to put site-specific files. !

!

The default value for --with-local-prefix is /usr/local ! regardless of the value of --prefix. Specifying ! --prefix has no effect on which directory GCC searches for local header files. This may seem counterintuitive, but actually it is logical. !

!

The purpose of --prefix is to specify where to install ! GCC. The local header files in /usr/local/include—if you put any in that directory—are not part of GCC. They are part of other programs—perhaps many others. (GCC installs its own header files in ! another directory which is based on the --prefix value.) !

!

Both the local-prefix include directory and the GCC-prefix include ! directory are part of GCC’s “system include” directories. Although these two directories are not fixed, they need to be searched in the proper order for the correct processing of the include_next directive. The local-prefix include directory is searched before the GCC-prefix include directory. Another characteristic of system include directories is that pedantic warnings are turned off for headers in these directories. !

!

Some autoconf macros add -I directory options to the compiler command line, to ensure that directories containing installed ! packages’ headers are searched. When directory is one of GCC’s system include directories, GCC will ignore the option so that system directories continue to be processed in the correct order. This may result in a search order different from what was specified but the directory will still be searched. !

!

GCC automatically searches for ordinary libraries using ! GCC_EXEC_PREFIX. Thus, when the same installation prefix is used for both GCC and packages, GCC will automatically search for both headers and libraries. This provides a configuration that is easy to use. GCC behaves in a manner similar to that when it is ! installed as a system compiler in /usr. !

!

Sites that need to install multiple versions of GCC may not want to use the above simple configuration. It is possible to use the ! --program-prefix, --program-suffix and ! --program-transform-name options to install multiple versions into a single directory, but it may be simpler to use different prefixes ! and the --with-local-prefix option to specify the location of the site-specific files for each version. It will then be necessary for users to specify explicitly the location of local site libraries ! (e.g., with LIBRARY_PATH). !

!

The same value can be used for both --with-local-prefix and ! --prefix provided it is not /usr. This can be used ! to avoid the default search of /usr/local/include. !

!

Do not specify /usr as the --with-local-prefix! ! The directory you use for --with-local-prefix must not ! contain any of the system’s standard header files. If it did contain them, certain programs would be miscompiled (including GNU Emacs, on certain targets), because this would override and nullify the header ! file corrections made by the fixincludes script. !

!

Indications are that people who use this option use it based on mistaken ideas of what it is for. People use it as if it specified where to install part of GCC. Perhaps they make this assumption because installing GCC creates the directory. !

!
!
--with-native-system-header-dir=dirname
!

Specifies that dirname is the directory that contains native system ! header files, rather than /usr/include. This option is most useful if you are creating a compiler that should be isolated from the system as much as possible. It is most commonly used with the ! --with-sysroot option and will cause GCC to search dirname inside the system root specified by that option. !

!
!
--enable-shared[=package[,…]]
!

Build shared versions of libraries, if shared libraries are supported on the target platform. Unlike GCC 2.95.x and earlier, shared libraries are enabled by default on all platforms that support shared libraries. !

!

If a list of packages is given as an argument, build shared libraries only for the listed packages. For other packages, only static libraries will be built. Package names currently recognized in the GCC tree are ! ‘libgcc’ (also known as ‘gcc’), ‘libstdc++’ (not ! ‘libstdc++-v3’), ‘libffi’, ‘zlib’, ‘boehm-gc’, ! ‘ada’, ‘libada’, ‘libjava’, ‘libgo’, and ‘libobjc’. ! Note ‘libiberty’ does not support shared libraries at all. !

!

Use --disable-shared to build only static libraries. Note that ! --disable-shared does not accept a list of package names as ! argument, only --enable-shared does. !

!
!
--with-gnu-as
!

Specify that the compiler should assume that the assembler it finds is the GNU assembler. However, this does not modify the rules to find an assembler and will result in confusion if the assembler found is not actually the GNU assembler. (Confusion may also result if the compiler finds the GNU assembler but has not been ! configured with --with-gnu-as.) If you have more than one assembler installed on your system, you may want to use this option in ! connection with --with-as=pathname or ! --with-build-time-tools=pathname. !

!

The following systems are the only ones where it makes a difference whether you use the GNU assembler. On any other system, ! --with-gnu-as has no effect. !

!
    !
  • ‘hppa1.0-any-any’ !
  • ‘hppa1.1-any-any’ !
  • ‘sparc-sun-solaris2.any’ !
  • ‘sparc64-any-solaris2.any’ !
!
!
--with-as=pathname
!

Specify that the compiler should use the assembler pointed to by pathname, rather than the one found by the standard rules to find an assembler, which are: !

    !
  • Unless GCC is being built with a cross compiler, check the ! libexec/gcc/target/version directory. ! libexec defaults to exec-prefix/libexec; exec-prefix defaults to prefix, which ! defaults to /usr/local unless overridden by the ! --prefix=pathname switch described above. target ! is the target system triple, such as ‘sparc-sun-solaris2.7’, and version denotes the GCC version, such as 3.0. !
  • If the target system is the same that you are building on, check ! operating system specific directories (e.g. /usr/ccs/bin on Sun Solaris 2). !
  • Check in the PATH for a tool whose name is prefixed by the target system triple. !
  • Check in the PATH for a tool whose name is not prefixed by the target system triple, if the host and target system triple are the same (in other words, we use a host tool if it can be used for ! the target as well). !
!

You may want to use --with-as if no assembler is installed in the directories listed above, or if you have multiple assemblers installed and want to choose one that is not found by the above rules. !

!
!
--with-gnu-ld
!

Same as --with-gnu-as but for the linker. !

!
!
--with-ld=pathname
!

Same as --with-as but for the linker. !

!
!
--with-stabs
!

Specify that stabs debugging information should be used instead of whatever format the host normally uses. Normally GCC uses the same debug format as the host system. !

!

On MIPS based systems and on Alphas, you must specify whether you want GCC to create the normal ECOFF debugging format, or to use BSD-style stabs passed through the ECOFF symbol table. The normal ECOFF debug format cannot fully handle languages other than C. BSD stabs format can handle other languages, but it only works with the GNU debugger GDB. !

!

Normally, GCC uses the ECOFF debugging format by default; if you ! prefer BSD stabs, specify --with-stabs when you configure GCC. !

!

No matter which default you choose when you configure GCC, the user ! can use the -gcoff and -gstabs+ options to specify explicitly the debug format for a particular compilation. !

!

--with-stabs is meaningful on the ISC system on the 386, also, if ! --with-gas is used. It selects use of stabs debugging information embedded in COFF output. This kind of debugging information supports C++ well; ordinary COFF debugging information does not. !

!

--with-stabs is also meaningful on 386 systems running SVR4. It selects use of stabs debugging information embedded in ELF output. The C++ compiler currently (2.6.0) does not support the DWARF debugging information normally used on 386 SVR4 platforms; stabs provide a workable alternative. This requires gas and gdb, as the normal SVR4 tools can not generate or interpret stabs. !

!
!
--with-tls=dialect
!

Specify the default TLS dialect, for systems were there is a choice. For ARM targets, possible values for dialect are gnu or gnu2, which select between the original GNU dialect and the GNU TLS descriptor-based dialect. !

!
!
--enable-multiarch
!

Specify whether to enable or disable multiarch support. The default is to check for glibc start files in a multiarch location, and enable it if the files are found. The auto detection is enabled for native builds, ! and for cross builds configured with --with-sysroot, and without ! --with-native-system-header-dir. More documentation about multiarch can be found at http://wiki.debian.org/Multiarch. !

!
!
--disable-multilib
!

Specify that multiple target libraries to support different target variants, calling conventions, etc. should not be built. The default is to build a predefined set of them. !

!

Some targets provide finer-grained control over which multilibs are built ! (e.g., --disable-softfloat): !

!
arm-*-*
!

fpu, 26bit, underscore, interwork, biendian, nofmult. !

!
!
m68*-*-*
!

softfloat, m68881, m68000, m68020. !

!
!
mips*-*-*
!

single-float, biendian, softfloat. !

!
!
powerpc*-*-*, rs6000*-*-*
!

aix64, pthread, softfloat, powercpu, powerpccpu, powerpcos, biendian, sysv, aix. +

+
+
!
!
--with-multilib-list=list
!
--without-multilib-list
!

Specify what multilibs to build. Currently only implemented for sh*-*-* and x86-64-*-linux*. !

!
!
sh*-*-*
!

list is a comma separated list of CPU names. These must be of the form sh* or m* (in which case they match the compiler option for that processor). The list should not contain any endian options - ! these are handled by --with-endian. !

!

If list is empty, then there will be no multilibs for extra processors. The multilib for the secondary endian remains enabled. !

!

As a special case, if an entry in the list starts with a ! ! (exclamation point), then it is added to the list of excluded multilibs. ! Entries of this sort should be compatible with ‘MULTILIB_EXCLUDES’ (once the leading ! has been stripped). !

!

If --with-multilib-list is not given, then a default set of ! multilibs is selected based on the value of --target. This is usually the complete set of libraries, but some targets imply a more specialized subset. !

!

Example 1: to configure a compiler for SH4A only, but supporting both endians, with little endian being the default: !

! 
--with-cpu=sh4a --with-endian=little,big --with-multilib-list=
!
! !

Example 2: to configure a compiler for both SH4A and SH4AL-DSP, but with only little endian SH4AL: !

! 
--with-cpu=sh4a --with-endian=little,big \
! --with-multilib-list=sh4al,!mb/m4al
!
! !
!
x86-64-*-linux*
!

list is a comma separated list of m32, m64 and mx32 to enable 32-bit, 64-bit and x32 run-time libraries, respectively. If list is empty, then there will be no multilibs and only the default run-time library will be enabled. !

!

If --with-multilib-list is not given, then only 32-bit and ! 64-bit run-time libraries will be enabled. !

!
!
--with-endian=endians
!

Specify what endians to use. Currently only implemented for sh*-*-*. !

!

endians may be one of the following: !

!
big
!

Use big endian exclusively. !

!
little
!

Use little endian exclusively. !

!
big,little
!

Use big endian by default. Provide a multilib for little endian. !

!
little,big
!

Use little endian by default. Provide a multilib for big endian. !

!
!
--enable-threads
!

Specify that the target supports threads. This affects the Objective-C compiler and runtime ! library, and exception handling for other languages like C++ and Java. On some systems, this is the default. !

!

In general, the best (and, in many cases, the only known) threading model available will be configured for use. Beware that on some systems, GCC has not been taught what threading models are generally ! available for the system. In this case, --enable-threads is an ! alias for --enable-threads=single. !

!
!
--disable-threads
!

Specify that threading support should be disabled for the system. ! This is an alias for --enable-threads=single. !

!
!
--enable-threads=lib
!

Specify that lib is the thread support library. This affects the Objective-C compiler and runtime library, and exception handling for other languages like C++ and Java. The possibilities for lib are: !

!
!
aix
!

AIX thread support. !

!
dce
!

DCE thread support. !

!
lynx
!

LynxOS thread support. !

!
mipssde
!

MIPS SDE thread support. !

!
no
!

This is an alias for ‘single’. !

!
posix
!

Generic POSIX/Unix98 thread support. !

!
rtems
!

RTEMS thread support. !

!
single
!

Disable thread support, should work for all platforms. !

!
tpf
!

TPF thread support. !

!
vxworks
!

VxWorks thread support. !

!
win32
!

Microsoft Win32 API thread support. !

!
!
--enable-tls
!

Specify that the target supports TLS (Thread Local Storage). Usually configure can correctly determine if TLS is supported. In cases where it guesses incorrectly, TLS can be explicitly enabled or disabled with ! --enable-tls or --disable-tls. This can happen if the assembler supports TLS but the C library does not, or if the assumptions made by the configure test are incorrect. !

!
!
--disable-tls
!

Specify that the target does not support TLS. ! This is an alias for --enable-tls=no. !

!
!
--with-cpu=cpu
!
--with-cpu-32=cpu
!
--with-cpu-64=cpu
!

Specify which cpu variant the compiler should generate code for by default. ! cpu will be used as the default value of the -mcpu= switch. This option is only supported on some targets, including ARM, i386, M68k, ! PowerPC, and SPARC. The --with-cpu-32 and ! --with-cpu-64 options specify separate default CPUs for 32-bit and 64-bit modes; these options are only supported for i386, x86-64 and PowerPC. !

!
!
--with-schedule=cpu
!
--with-arch=cpu
!
--with-arch-32=cpu
!
--with-arch-64=cpu
!
--with-tune=cpu
!
--with-tune-32=cpu
!
--with-tune-64=cpu
!
--with-abi=abi
!
--with-fpu=type
!
--with-float=type
!

These configure options provide default values for the -mschedule=, ! -march=, -mtune=, -mabi=, and -mfpu= ! options and for -mhard-float or -msoft-float. As with ! --with-cpu, which switches will be accepted and acceptable values of the arguments depend on the target. !

!
!
--with-mode=mode
!

Specify if the compiler should default to -marm or -mthumb. This option is only supported on ARM targets. !

!
!
--with-stack-offset=num
!

This option sets the default for the -mstack-offset=num option, and will thus generally also control the setting of this option for libraries. This option is only supported on Epiphany targets. !

!
!
--with-fpmath=isa
!

This options sets -mfpmath=sse by default and specifies the default ! ISA for floating-point arithmetics. You can select either ‘sse’ which ! enables -msse2 or ‘avx’ which enables -mavx by default. This option is only supported on i386 and x86-64 targets. !

!
!
--with-divide=type
!

Specify how the compiler should generate code for checking for ! division by zero. This option is only supported on the MIPS target. The possibilities for type are: !

!
traps
!

Division by zero checks use conditional traps (this is the default on ! systems that support conditional traps). !

!
breaks
!

Division by zero checks use the break instruction. !

! !
!
--with-llsc
!

On MIPS targets, make -mllsc the default when no ! -mno-llsc option is passed. This is the default for Linux-based targets, as the kernel will emulate them if the ISA does not provide them. !

!
!
--without-llsc
!

On MIPS targets, make -mno-llsc the default when no ! -mllsc option is passed. !

!
!
--with-synci
!

On MIPS targets, make -msynci the default when no ! -mno-synci option is passed. !

!
!
--without-synci
!

On MIPS targets, make -mno-synci the default when no ! -msynci option is passed. This is the default. !

!
!
--with-mips-plt
!

On MIPS targets, make use of copy relocations and PLTs. These features are extensions to the traditional SVR4-based MIPS ABIs and require support from GNU binutils and the runtime C library. !

!
!
--enable-__cxa_atexit
!

Define if you want to use __cxa_atexit, rather than atexit, to ! register C++ destructors for local statics and global objects. This is essential for fully standards-compliant handling of destructors, but requires __cxa_atexit in libc. This option is currently only available on systems with GNU libc. When enabled, this will cause ! -fuse-cxa-atexit to be passed by default. !

!
!
--enable-gnu-indirect-function
!

Define if you want to enable the ifunc attribute. This option is currently only available on systems with GNU libc on certain targets. !

!
!
--enable-target-optspace
!

Specify that target ! libraries should be optimized for code space instead of code speed. This is the default for the m32r platform. !

!
!
--with-cpp-install-dir=dirname
!

Specify that the user visible cpp program should be installed ! in prefix/dirname/cpp, in addition to bindir. !

!
!
--enable-comdat
!

Enable COMDAT group support. This is primarily used to override the automatically detected value. !

!
!
--enable-initfini-array
!

Force the use of sections .init_array and .fini_array (instead of .init and .fini) for constructors and ! destructors. Option --disable-initfini-array has the opposite effect. If neither option is specified, the configure script will try to guess whether the .init_array and .fini_array sections are supported and, if they are, use them. !

!
!
--enable-maintainer-mode
!

The build rules that regenerate the Autoconf and Automake output files as ! well as the GCC master message catalog gcc.pot are normally disabled. This is because it can only be rebuilt if the complete source tree is present. If you have changed the sources and want to rebuild the ! catalog, configuring with --enable-maintainer-mode will enable this. Note that you need a recent version of the gettext tools to do so. !

!
!
--disable-bootstrap
!

For a native build, the default configuration is to perform ! a 3-stage bootstrap of the compiler when ‘make’ is invoked, testing that GCC can compile itself correctly. If you want to disable ! this process, you can configure with --disable-bootstrap. !

!
!
--enable-bootstrap
!

In special cases, you may want to perform a 3-stage build ! even if the target and host triplets are different. This is possible when the host can run code compiled for ! the target (e.g. host is i686-linux, target is i486-linux). Starting from GCC 4.2, to do this you have to configure explicitly ! with --enable-bootstrap. !

!
!
--enable-generated-files-in-srcdir
!

Neither the .c and .h files that are generated from Bison and flex nor the info manuals and man pages that are built from the .texi files are present in the SVN development tree. When building GCC from that development tree, or from one of our snapshots, those generated files are placed in your build directory, which allows for the source to be in a readonly directory. !

!

If you configure with --enable-generated-files-in-srcdir then those generated files will go into the source directory. This is mainly intended for generating release or prerelease tarballs of the GCC sources, since it is not a requirement that the users of source releases to have flex, Bison, or makeinfo. !

!
!
--enable-version-specific-runtime-libs
!

Specify that runtime libraries should be installed in the compiler specific ! subdirectory (libdir/gcc) rather than the usual places. In ! addition, ‘libstdc++’’s include files will be installed into libdir unless you overruled it by using ! --with-gxx-include-dir=dirname. Using this option is particularly useful if you intend to use several versions of GCC in ! parallel. This is currently supported by ‘libgfortran’, ! ‘libjava’, ‘libmudflap’, ‘libstdc++’, and ‘libobjc’. !

!
!
--enable-languages=lang1,lang2,…
!

Specify that only a particular subset of compilers and their runtime libraries should be built. For a list of valid values for langN you can issue the following command in the ! gcc directory of your GCC source tree:
!

! 
grep language= */config-lang.in
!
!

Currently, you can use any of the following: all, ada, c, c++, fortran, ! go, java, objc, obj-c++. ! Building the Ada compiler has special requirements, see below. If you do not pass this flag, or specify the option all, then all ! default languages available in the gcc sub-tree will be configured. Ada, Go and Objective-C++ are not default languages; the rest are. !

!
!
--enable-stage1-languages=lang1,lang2,…
!

Specify that a particular subset of compilers and their runtime libraries should be built with the system C compiler during stage 1 of the bootstrap process, rather than only in later stages with the bootstrapped C compiler. The list of valid values is the same as for ! --enable-languages, and the option all will select all ! of the languages enabled by --enable-languages. This option is primarily useful for GCC development; for instance, when a development version of the compiler cannot bootstrap due to compiler bugs, or when one is debugging front ends other than the C front end. When this option is used, one can then build the target libraries for the ! specified languages with the stage-1 compiler by using make ! stage1-bubble all-target, or run the testsuite on the stage-1 compiler ! for the specified languages using make stage1-start check-gcc. !

!
!
--disable-libada
!

Specify that the run-time libraries and tools used by GNAT should not be built. This can be useful for debugging, or for compatibility with previous Ada build procedures, when it was required to explicitly ! do a ‘make -C gcc gnatlib_and_tools’. !

!
!
--disable-libssp
!

Specify that the run-time libraries for stack smashing protection should not be built. !

!
!
--disable-libquadmath
!

Specify that the GCC quad-precision math library should not be built. On some systems, the library is required to be linkable when building ! the Fortran front end, unless --disable-libquadmath-support is used. !

!
!
--disable-libquadmath-support
!

Specify that the Fortran front end and libgfortran do not add support for libquadmath on systems supporting it. !

!
!
--disable-libgomp
!

Specify that the run-time libraries used by GOMP should not be built. !

!
!
--with-dwarf2
!

Specify that the compiler should use DWARF 2 debugging information as the default. !

!
!
--enable-targets=all
!
--enable-targets=target_list
!

Some GCC targets, e.g. powerpc64-linux, build bi-arch compilers. These are compilers that are able to generate either 64-bit or 32-bit ! code. Typically, the corresponding 32-bit target, e.g. powerpc-linux for powerpc64-linux, only generates 32-bit code. This option enables the 32-bit target to be a bi-arch compiler, which is useful when you want a bi-arch compiler that defaults to 32-bit, and ! you are building a bi-arch or multi-arch binutils in a combined tree. On mips-linux, this will build a tri-arch compiler (ABI o32/n32/64), ! defaulted to o32. Currently, this option only affects sparc-linux, powerpc-linux, x86-linux, mips-linux and s390-linux. !

!
!
--enable-secureplt
!

This option enables -msecure-plt by default for powerpc-linux. See “RS/6000 and PowerPC Options” in the main manual !

!
!
--enable-cld
!

This option enables -mcld by default for 32-bit x86 targets. See “i386 and x86-64 Options” in the main manual !

!
!
--enable-win32-registry
!
--enable-win32-registry=key
!
--disable-win32-registry
!

The --enable-win32-registry option enables Microsoft Windows-hosted GCC to look up installations paths in the registry using the following key: +

+
+ 
HKEY_LOCAL_MACHINE\SOFTWARE\Free Software Foundation\key
+
!

key defaults to GCC version number, and can be overridden by the ! --enable-win32-registry=key option. Vendors and distributors who use custom installers are encouraged to provide a different key, perhaps one comprised of vendor name and GCC version number, to avoid conflict with existing installations. This feature is enabled ! by default, and can be disabled by --disable-win32-registry option. This option has no effect on the other hosts. !

!
!
--nfp
!

Specify that the machine does not have a floating point unit. This ! option only applies to ‘m68k-sun-sunosn’. On any other ! system, --nfp has no effect. !

!
!
--enable-werror
!
--disable-werror
!
--enable-werror=yes
!
--enable-werror=no
!

When you specify this option, it controls whether certain files in the ! compiler are built with -Werror in bootstrap stage2 and later. ! If you don’t specify it, -Werror is turned on for the main development trunk. However it defaults to off for release branches and ! final releases. The specific files which get -Werror are controlled by the Makefiles. !

!
!
--enable-checking
!
--enable-checking=list
!

When you specify this option, the compiler is built to perform internal consistency checks of the requested complexity. This does not change the generated code, but adds error checking within the compiler. This will slow down the compiler and may only work properly if you are building ! the compiler with GCC. This is ‘yes’ by default when building ! from SVN or snapshots, but ‘release’ for releases. The default ! for building the stage1 compiler is ‘yes’. More control over the checks may be had by specifying list. The categories of ! checks available are ‘yes’ (most common checks ! ‘assert,misc,tree,gc,rtlflag,runtime’), ‘no’ (no checks at ! all), ‘all’ (all but ‘valgrind’), ‘release’ (cheapest ! checks ‘assert,runtime’) or ‘none’ (same as ‘no’). ! Individual checks can be enabled with these flags ‘assert’, ! ‘df’, ‘fold’, ‘gc’, ‘gcac’ ‘misc’, ‘rtl’, ! ‘rtlflag’, ‘runtime’, ‘tree’, and ‘valgrind’. !

!

The ‘valgrind’ check requires the external valgrind simulator, available from http://valgrind.org/. The ! ‘df’, ‘rtl’, ‘gcac’ and ‘valgrind’ checks are very expensive. ! To disable all checking, ‘--disable-checking’ or ! ‘--enable-checking=none’ must be explicitly requested. Disabling assertions will make the compiler and runtime slightly faster but increase the risk of undetected internal errors causing wrong code to be generated. !

!
!
--disable-stage1-checking
!
--enable-stage1-checking
!
--enable-stage1-checking=list
!

If no --enable-checking option is specified the stage1 ! compiler will be built with ‘yes’ checking enabled, otherwise the stage1 checking flags are the same as specified by ! --enable-checking. To build the stage1 compiler with ! different checking options use --enable-stage1-checking. ! The list of checking options is the same as for --enable-checking. If your system is too slow or too small to bootstrap a released compiler ! with checking for stage1 enabled, you can use ‘--disable-stage1-checking’ to disable checking for the stage1 compiler. !

!
!
--enable-coverage
!
--enable-coverage=level
!

With this option, the compiler is built to collect self coverage information, every time it is run. This is for internal development purposes, and only works when the compiler is being built with gcc. The level argument controls whether the compiler is built optimized or ! not, values are ‘opt’ and ‘noopt’. For coverage analysis you want to disable optimization, for performance analysis you want to enable optimization. When coverage is enabled, the default level is without optimization. !

!
!
--enable-gather-detailed-mem-stats
!

When this option is specified more detailed information on memory allocation is gathered. This information is printed when using ! -fmem-report. !

!
!
--enable-nls
!
--disable-nls
!

The --enable-nls option enables Native Language Support (NLS), which lets GCC output diagnostics in languages other than American English. Native Language Support is enabled by default if not doing a ! canadian cross build. The --disable-nls option disables NLS. !

!
!
--with-included-gettext
!

If NLS is enabled, the --with-included-gettext option causes the build ! procedure to prefer its copy of GNU gettext. !

!
!
--with-catgets
!

If NLS is enabled, and if the host lacks gettext but has the inferior catgets interface, the GCC build procedure normally ! ignores catgets and instead uses GCC’s copy of the GNU ! gettext library. The --with-catgets option causes the ! build procedure to use the host’s catgets in this situation. !

!
!
--with-libiconv-prefix=dir
!

Search for libiconv header files in dir/include and ! libiconv library files in dir/lib. !

!
!
--enable-obsolete
!

Enable configuration for an obsoleted system. If you attempt to configure GCC for a system (build, host, or target) which has been obsoleted, and you do not specify this flag, configure will halt with an error message. !

!

All support for systems which have been obsoleted in one release of GCC is removed entirely in the next major release, unless someone steps forward to maintain the port. !

!
!
--enable-decimal-float
!
--enable-decimal-float=yes
!
--enable-decimal-float=no
!
--enable-decimal-float=bid
!
--enable-decimal-float=dpd
!
--disable-decimal-float
!

Enable (or disable) support for the C decimal floating point extension that is in the IEEE 754-2008 standard. This is enabled by default only on PowerPC, i386, and x86_64 GNU/Linux systems. Other systems may also support it, but require the user to specifically enable it. You can optionally control which decimal floating point format is used (either ! ‘bid’ or ‘dpd’). The ‘bid’ (binary integer decimal) ! format is default on i386 and x86_64 systems, and the ‘dpd’ (densely packed decimal) format is default on PowerPC systems. !

!
!
--enable-fixed-point
!
--disable-fixed-point
!

Enable (or disable) support for C fixed-point arithmetic. This option is enabled by default for some targets (such as MIPS) which have hardware-support for fixed-point operations. On other targets, you may enable this option manually. !

!
!
--with-long-double-128
!

Specify if long double type should be 128-bit by default on selected GNU/Linux architectures. If using --without-long-double-128, ! long double will be by default 64-bit, the same as double type. When neither of these configure options are used, the default will be 128-bit long double when built against GNU C Library 2.4 and later, 64-bit long double otherwise. !

!
!
--with-gmp=pathname
!
--with-gmp-include=pathname
!
--with-gmp-lib=pathname
!
--with-mpfr=pathname
!
--with-mpfr-include=pathname
!
--with-mpfr-lib=pathname
!
--with-mpc=pathname
!
--with-mpc-include=pathname
!
--with-mpc-lib=pathname
!

If you want to build GCC but do not have the GMP library, the MPFR library and/or the MPC library installed in a standard location and do not have their sources present in the GCC source tree then you can explicitly specify the directory where they are installed ! (‘--with-gmp=gmpinstalldir’, ! ‘--with-mpfr=mpfrinstalldir’, ! ‘--with-mpc=mpcinstalldir’). The ! --with-gmp=gmpinstalldir option is shorthand for ! --with-gmp-lib=gmpinstalldir/lib and ! --with-gmp-include=gmpinstalldir/include. Likewise the ! --with-mpfr=mpfrinstalldir option is shorthand for ! --with-mpfr-lib=mpfrinstalldir/lib and ! --with-mpfr-include=mpfrinstalldir/include, also the ! --with-mpc=mpcinstalldir option is shorthand for ! --with-mpc-lib=mpcinstalldir/lib and ! --with-mpc-include=mpcinstalldir/include. If these shorthand assumptions are not correct, you can use the explicit include and lib options directly. You might also need to ensure the shared libraries can be found by the dynamic linker when building and using GCC, for example by setting the runtime shared library path ! variable (LD_LIBRARY_PATH on GNU/Linux and Solaris systems). !

!

These flags are applicable to the host platform only. When building a cross compiler, they will not be used to configure target libraries. !

!
!
--with-isl=pathname
!
--with-isl-include=pathname
!
--with-isl-lib=pathname
!
--with-cloog=pathname
!
--with-cloog-include=pathname
!
--with-cloog-lib=pathname
!

If you do not have ISL and the CLooG libraries installed in a standard location and you want to build GCC, you can explicitly specify the directory where they are installed ! (‘--with-isl=islinstalldir’, ! ‘--with-cloog=clooginstalldir’). The ! --with-isl=islinstalldir option is shorthand for ! --with-isl-lib=islinstalldir/lib and ! --with-isl-include=islinstalldir/include. Likewise the ! --with-cloog=clooginstalldir option is shorthand for ! --with-cloog-lib=clooginstalldir/lib and ! --with-cloog-include=clooginstalldir/include. If these shorthand assumptions are not correct, you can use the explicit include and lib options directly. !

!

These flags are applicable to the host platform only. When building a cross compiler, they will not be used to configure target libraries. !

!
!
--with-host-libstdcxx=linker-args
!

If you are linking with a static copy of PPL, you can use this option to specify how the linker should find the standard C++ library used internally by PPL. Typical values of linker-args might be ! ‘-lstdc++’ or ‘-Wl,-Bstatic,-lstdc++,-Bdynamic -lm’. If you are linking with a shared copy of PPL, you probably do not need this option; shared library dependencies will cause the linker to search for the standard C++ library automatically. !

!
!
--with-stage1-ldflags=flags
!

This option may be used to set linker flags to be used when linking stage 1 of GCC. These are also used when linking GCC if configured with ! --disable-bootstrap. By default no special flags are used. !

!
!
--with-stage1-libs=libs
!

This option may be used to set libraries to be used when linking stage 1 of GCC. These are also used when linking GCC if configured with ! --disable-bootstrap. The default is the argument to ! --with-host-libstdcxx, if specified. !

!
!
--with-boot-ldflags=flags
!

This option may be used to set linker flags to be used when linking stage 2 and later when bootstrapping GCC. If neither –with-boot-libs nor –with-host-libstdcxx is set to a value, then the default is ! ‘-static-libstdc++ -static-libgcc’. !

!
!
--with-boot-libs=libs
!

This option may be used to set libraries to be used when linking stage 2 and later when bootstrapping GCC. The default is the argument to ! --with-host-libstdcxx, if specified. !

!
!
--with-debug-prefix-map=map
!

Convert source directory names using -fdebug-prefix-map when building runtime libraries. ‘map’ is a space-separated ! list of maps of the form ‘old=new’. !

!
!
--enable-linker-build-id
!

Tells GCC to pass --build-id option to the linker for all final ! links (links performed without the -r or --relocatable option), if the linker supports it. If you specify ! --enable-linker-build-id, but your linker does not ! support --build-id option, a warning is issued and the ! --enable-linker-build-id option is ignored. The default is off. !

!
!
--with-linker-hash-style=choice
!

Tells GCC to pass --hash-style=choice option to the linker for all final links. choice can be one of ! ‘sysv’, ‘gnu’, and ‘both’ where ‘sysv’ is the default. !

!
!
--enable-gnu-unique-object
!
--disable-gnu-unique-object
!

Tells GCC to use the gnu_unique_object relocation for C++ template static data members and inline function local statics. Enabled by default for a native toolchain with an assembler that accepts it and GLIBC 2.11 or above, otherwise disabled. !

!
!
--enable-lto
!
--disable-lto
!

Enable support for link-time optimization (LTO). This is enabled by ! default, and may be disabled using --disable-lto. !

!
!
--with-plugin-ld=pathname
!

Enable an alternate linker to be used at link-time optimization (LTO) ! link time when -fuse-linker-plugin is enabled. This linker should have plugin support such as gold starting with ! version 2.20 or GNU ld starting with version 2.21. ! See -fuse-linker-plugin for details. !

!
!
--enable-canonical-system-headers
!
--disable-canonical-system-headers
!

Enable system header path canonicalization for libcpp. This can produce shorter header file paths in diagnostics and dependency output files, but these changed header paths may conflict with some compilation environments. Enabled by default, and may be disabled using ! --disable-canonical-system-headers. !

! !

Cross-Compiler-Specific Options

The following options only apply to building cross compilers. !

!
!
--with-sysroot
!
--with-sysroot=dir
!

Tells GCC to consider dir as the root of a tree that contains ! (a subset of) the root filesystem of the target operating system. Target system headers, libraries and run-time object files will be searched for in there. More specifically, this acts as if ! --sysroot=dir was added to the default options of the built compiler. The specified directory is not copied into the ! install tree, unlike the options --with-headers and ! --with-libs that this option obsoletes. The default value, ! in case --with-sysroot is not given an argument, is ! ${gcc_tooldir}/sys-root. If the specified directory is a ! subdirectory of ${exec_prefix}, then it will be found relative to the GCC binaries if the installation tree is moved. !

!

This option affects the system root for the compiler used to build target libraries (which runs on the build system) and the compiler newly installed with make install; it does not affect the compiler which is used to build GCC itself. !

!

If you specify the --with-native-system-header-dir=dirname option then the compiler will search that directory within dirname for ! native system headers rather than the default /usr/include. !

!
!
--with-build-sysroot
!
--with-build-sysroot=dir
!

Tells GCC to consider dir as the system root (see ! --with-sysroot) while building target libraries, instead of ! the directory specified with --with-sysroot. This option is ! only useful when you are already using --with-sysroot. You ! can use --with-build-sysroot when you are configuring with ! --prefix set to a directory that is different from the one in which you are installing GCC and your target libraries. !

!

This option affects the system root for the compiler used to build target libraries (which runs on the build system); it does not affect the compiler which is used to build GCC itself. !

!

If you specify the --with-native-system-header-dir=dirname option then the compiler will search that directory within dirname for ! native system headers rather than the default /usr/include. !

!
!
--with-headers
!
--with-headers=dir
!

Deprecated in favor of --with-sysroot. ! Specifies that target headers are available when building a cross compiler. The dir argument specifies a directory which has the target include ! files. These include files will be copied into the gcc install ! directory. This option with the dir argument is required when ! building a cross compiler, if prefix/target/sys-include ! doesn’t pre-exist. If prefix/target/sys-include does ! pre-exist, the dir argument may be omitted. fixincludes will be run on these files to make them compatible with GCC. !

!
!
--without-headers
!

Tells GCC not use any target headers from a libc when building a cross compiler. When crossing to GNU/Linux, you need the headers so GCC can build the exception handling for libgcc. !

!
!
--with-libs
!
--with-libs="dir1 dir2 … dirN"
!

Deprecated in favor of --with-sysroot. Specifies a list of directories which contain the target runtime ! libraries. These libraries will be copied into the gcc install directory. If the directory list is omitted, this option has no effect. !

!
!
--with-newlib
!

Specifies that ‘newlib’ is being used as the target C library. This causes __eprintf to be ! omitted from libgcc.a on the assumption that it will be provided by ! ‘newlib’. !

!
!
--with-avrlibc
!

Specifies that ‘AVR-Libc’ is being used as the target C library. This causes float support ! functions like __addsf3 to be omitted from libgcc.a on ! the assumption that it will be provided by libm.a. For more ! technical details, cf. PR54461. This option is only supported for the AVR target. It is not supported for RTEMS configurations, which currently use newlib. The option is supported since version 4.7.2 and is the default in 4.8.0 and newer. !

!
!
--with-build-time-tools=dir
!

Specifies where to find the set of target tools (assembler, linker, etc.) that will be used while building GCC itself. This option can be useful if the directory layouts are different between the system you are building GCC on, and the system where you will deploy it. !

!

For example, on an ‘ia64-hp-hpux’ system, you may have the GNU ! assembler and linker in /usr/bin, and the native tools in a different path, and build a toolchain that expects to find the ! native tools in /usr/bin. !

!

When you use this option, you should ensure that dir includes ! ar, as, ld, nm, ! ranlib and strip if necessary, and possibly ! objdump. Otherwise, GCC may use an inconsistent set of ! tools. !

! !

Java-Specific Options

The following option applies to the build of the Java front end. !

!
!
--disable-libgcj
!

Specify that the run-time libraries used by GCJ should not be built. This is useful in case you intend ! to use GCJ with some other run-time, or you’re going to install it separately, or it just happens not to build on your particular machine. In general, if the Java front end is enabled, the GCJ ! libraries will be enabled too, unless they’re known to not work on ! the target platform. If GCJ is enabled but ‘libgcj’ isn’t built, you may need to port it; in this case, before modifying the top-level ! configure.in so that ‘libgcj’ is enabled by default on this platform, ! you may use --enable-libgcj to override the default. !

!
!
!

The following options apply to building ‘libgcj’. !

! !

General Options

!
!
--enable-java-maintainer-mode
!

By default the ‘libjava’ build will not attempt to compile the ! .java source files to .class. Instead, it will use the ! .class files from the source tree. If you use this option you ! must have executables named ecj1 and gjavah in your path for use by the build. You must use this option if you intend to ! modify any .java files in libjava. !

!
!
--with-java-home=dirname
!

This ‘libjava’ option overrides the default value of the ! ‘java.home’ system property. It is also used to set ! ‘sun.boot.class.path’ to dirname/lib/rt.jar. By ! default ‘java.home’ is set to prefix and ! ‘sun.boot.class.path’ to ! datadir/java/libgcj-version.jar. !

!
!
--with-ecj-jar=filename
!

This option can be used to specify the location of an external jar file containing the Eclipse Java compiler. A specially modified ! version of this compiler is used by gcj to parse ! .java source files. If this option is given, the ! ‘libjava’ build will create and install an ecj1 executable which uses this jar file at runtime. !

!

If this option is not given, but an ecj.jar file is found in ! the topmost source tree at configure time, then the ‘libgcj’ ! build will create and install ecj1, and will also install the ! discovered ecj.jar into a suitable place in the install tree. !

!

If ecj1 is not installed, then the user will have to supply one ! on his path in order for gcj to properly parse .java source files. A suitable jar is available from ftp://sourceware.org/pub/java/. !

!
!
--disable-getenv-properties
!

Don’t set system properties from GCJ_PROPERTIES. !

!
!
--enable-hash-synchronization
!

Use a global hash table for monitor locks. Ordinarily, ! ‘libgcj’’s ‘configure’ script automatically makes the correct choice for this option for your platform. Only use this if you know you need the library to be configured differently. !

!
!
--enable-interpreter
!

Enable the Java interpreter. The interpreter is automatically enabled by default on all platforms that support it. This option is really only useful if you want to disable the interpreter ! (using --disable-interpreter). !

!
!
--disable-java-net
!

Disable java.net. This disables the native part of java.net only, using non-functional stubs for native method implementations. !

!
!
--disable-jvmpi
!

Disable JVMPI support. !

!
!
--disable-libgcj-bc
!

Disable BC ABI compilation of certain parts of libgcj. By default, ! some portions of libgcj are compiled with -findirect-dispatch ! and -fno-indirect-classes, allowing them to be overridden at run-time. !

!

If --disable-libgcj-bc is specified, libgcj is built without these options. This allows the compile-time linker to resolve dependencies when statically linking to libgcj. However it makes it impossible to override the affected portions of libgcj at run-time. !

!
!
--enable-reduced-reflection
!

Build most of libgcj with -freduced-reflection. This reduces the size of libgcj at the expense of not being able to do accurate reflection on the classes it contains. This option is safe if you know that code using libgcj will never use reflection on the standard runtime classes in libgcj (including using serialization, RMI or CORBA). !

!
!
--with-ecos
!

Enable runtime eCos target support. !

!
!
--without-libffi
!

Don’t use ‘libffi’. This will disable the interpreter and JNI ! support as well, as these require ‘libffi’ to work. !

!
!
--enable-libgcj-debug
!

Enable runtime debugging code. !

!
!
--enable-libgcj-multifile
!

If specified, causes all .java source files to be ! compiled into .class files in one invocation of ! ‘gcj’. This can speed up build time, but is more resource-intensive. If this option is unspecified or ! disabled, ‘gcj’ is invoked once for each .java ! file to compile into a .class file. !

!
!
--with-libiconv-prefix=DIR
!

Search for libiconv in DIR/include and DIR/lib. !

!
!
--enable-sjlj-exceptions
!

Force use of the setjmp/longjmp-based scheme for exceptions. ! ‘configure’ ordinarily picks the correct value based on the platform. Only use this option if you are sure you need a different setting. !

!
!
--with-system-zlib
!

Use installed ‘zlib’ rather than that included with GCC. !

!
!
--with-win32-nlsapi=ansi, unicows or unicode
!

Indicates how MinGW ‘libgcj’ translates between UNICODE characters and the Win32 API. !

!
!
--enable-java-home
!

If enabled, this creates a JPackage compatible SDK environment during install. Note that if –enable-java-home is used, –with-arch-directory=ARCH must also be specified. !

!
!
--with-arch-directory=ARCH
!

Specifies the name to use for the jre/lib/ARCH directory in the SDK environment created when –enable-java-home is passed. Typical names for this directory include i386, amd64, ia64, etc. !

!
!
--with-os-directory=DIR
!

Specifies the OS directory for the SDK include directory. This is set to auto ! detect, and is typically ’linux’. !

!
!
--with-origin-name=NAME
!

Specifies the JPackage origin name. This defaults to the ’gcj’ in java-1.5.0-gcj. !

!
!
--with-arch-suffix=SUFFIX
!

Specifies the suffix for the sdk directory. Defaults to the empty string. ! Examples include ’.x86_64’ in ’java-1.5.0-gcj-1.5.0.0.x86_64’. !

!
!
--with-jvm-root-dir=DIR
!

Specifies where to install the SDK. Default is $(prefix)/lib/jvm. !

!
!
--with-jvm-jar-dir=DIR
!

Specifies where to install jars. Default is $(prefix)/lib/jvm-exports. !

!
!
--with-python-dir=DIR
!

Specifies where to install the Python modules used for aot-compile. DIR should not include the prefix used in installation. For example, if the Python modules are to be installed in /usr/lib/python2.5/site-packages, then –with-python-dir=/lib/python2.5/site-packages should be passed. If this is not specified, then the Python modules are installed in $(prefix)/share/python. !

!
!
--enable-aot-compile-rpm
!

Adds aot-compile-rpm to the list of installed scripts. !

!
!
--enable-browser-plugin
!

Build the gcjwebplugin web browser plugin. !

!
!
--enable-static-libjava
!

Build static libraries in libjava. The default is to only build shared libraries. !

!
!
ansi
!

Use the single-byte char and the Win32 A functions natively, translating to and from UNICODE when using these functions. If unspecified, this is the default. !

!
!
unicows
!

Use the WCHAR and Win32 W functions natively. Adds ! -lunicows to libgcj.spec to link with ‘libunicows’. ! unicows.dll needs to be deployed on Microsoft Windows 9X machines ! running built executables. libunicows.a, an open-source ! import library around Microsoft’s unicows.dll, is obtained from http://libunicows.sourceforge.net/, which also gives details ! on getting unicows.dll from Microsoft. !

!
!
unicode
!

Use the WCHAR and Win32 W functions natively. Does not ! add -lunicows to libgcj.spec. The built executables will ! only run on Microsoft Windows NT and above. !

!
!
! !

AWT-Specific Options

!
!
--with-x
!

Use the X Window System. !

!
!
--enable-java-awt=PEER(S)
!

Specifies the AWT peer library or libraries to build alongside ! ‘libgcj’. If this option is unspecified or disabled, AWT ! will be non-functional. Current valid values are gtk and ! xlib. Multiple libraries should be separated by a ! comma (i.e. --enable-java-awt=gtk,xlib). !

!
!
--enable-gtk-cairo
!

Build the cairo Graphics2D implementation on GTK. !

!
!
--enable-java-gc=TYPE
!

Choose garbage collector. Defaults to boehm if unspecified. !

!
!
--disable-gtktest
!

Do not try to compile and run a test GTK+ program. !

!
!
--disable-glibtest
!

Do not try to compile and run a test GLIB program. !

!
!
--with-libart-prefix=PFX
!

Prefix where libart is installed (optional). !

!
!
--with-libart-exec-prefix=PFX
!

Exec prefix where libart is installed (optional). !

!
!
--disable-libarttest
!

Do not try to compile and run a test libart program. !

!
!
! !

Overriding configure test results

!

Sometimes, it might be necessary to override the result of some ! configure test, for example in order to ease porting to a new ! system or work around a bug in a test. The toplevel configure ! script provides three variables for this: !

!
!
build_configargs
!
!

The contents of this variable is passed to all build configure ! scripts. !

!
!
host_configargs
!
!

The contents of this variable is passed to all host configure ! scripts. !

!
!
target_configargs
!
!

The contents of this variable is passed to all target configure ! scripts. !

!
!
!

In order to avoid shell and make quoting issues for complex ! overrides, you can pass a setting for CONFIG_SITE and set ! variables in the site file. !

Downloading GCC

- - GCC is distributed via SVN and FTP - tarballs compressed with gzip or - bzip2. !

Please refer to the releases web page ! for information on how to obtain GCC. !

The source distribution includes the C, C++, Objective-C, Fortran, Java, and Ada (in the case of GCC 3.1 and later) compilers, as well as ! runtime libraries for C++, Objective-C, Fortran, and Java. For previous versions these were downloadable as separate components such as the core GCC distribution, which included the C language front end and shared components, and language-specific distributions including the language front end and the language runtime (where appropriate). ! !

If you also intend to build binutils (either to upgrade an existing installation or for use in place of the corresponding tools of your OS), unpack the binutils distribution either in the same directory or a separate one. In the latter case, add symbolic links to any components of the binutils you intend to build alongside the compiler ! (bfd, binutils, gas, gprof, ld, ! opcodes, ...) to the directory containing the GCC sources. ! !

Likewise the GMP, MPFR and MPC libraries can be automatically built together with GCC. Unpack the GMP, MPFR and/or MPC source distributions in the directory containing the GCC sources and rename ! their directories to gmp, mpfr and mpc, respectively (or use symbolic links with the same name). -

If you also intend to build binutils (either to upgrade an existing installation or for use in place of the corresponding tools of your OS), unpack the binutils distribution either in the same directory or a separate one. In the latter case, add symbolic links to any components of the binutils you intend to build alongside the compiler ! (bfd, binutils, gas, gprof, ld, ! opcodes, …) to the directory containing the GCC sources. !

!

Likewise the GMP, MPFR and MPC libraries can be automatically built together with GCC. Unpack the GMP, MPFR and/or MPC source distributions in the directory containing the GCC sources and rename ! their directories to gmp, mpfr and mpc, respectively (or use symbolic links with the same name). +

Installing GCC: Final installation

! Now that GCC has been built (and optionally tested), you can install it with ! 
     cd objdir && make install
!
!

We strongly recommend to install into a target directory where there is no previous version of GCC present. Also, the GNAT runtime should not be stripped, as this would break certain features of the debugger that depend on this debugging information (catching Ada exceptions for instance). ! !

That step completes the installation of GCC; user level binaries can ! be found in prefix/bin where prefix is the value ! you specified with the --prefix to configure (or ! /usr/local by default). (If you specified --bindir, that directory will be used instead; otherwise, if you specified ! --exec-prefix, exec-prefix/bin will be used.) Headers for the C++ and Java libraries are installed in ! prefix/include; libraries in libdir ! (normally prefix/lib); internal parts of the compiler in ! libdir/gcc and libexecdir/gcc; documentation in info format in infodir (normally ! prefix/info). ! !

When installing cross-compilers, GCC's executables are not only installed into bindir, that ! is, exec-prefix/bin, but additionally into ! exec-prefix/target-alias/bin, if that directory ! exists. Typically, such tooldirs hold target-specific binutils, including assembler and linker. ! !

Installation into a temporary staging area or into a chroot jail can be achieved with the command ! 

     make DESTDIR=path-to-rootdir install
!
!

where path-to-rootdir is the absolute path of a directory relative to which all installation paths will be interpreted. Note that the directory specified by DESTDIR need not exist yet; it will be created if necessary. ! !

There is a subtle point with tooldirs and DESTDIR: If you relocate a cross-compiler installation with ! e.g. ‘DESTDIR=rootdir’, then the directory ! rootdir/exec-prefix/target-alias/bin will be filled with duplicated GCC executables only if it already exists, it will not be created otherwise. This is regarded as a feature, not as a bug, because it gives slightly more control to the packagers using the DESTDIR feature. !

You can install stripped programs and libraries with ! ! 

     make install-strip
!
!

If you are bootstrapping a released version of GCC then please quickly review the build status page for your release, available from ! http://gcc.gnu.org/buildstat.html. If your system is not listed for the version of GCC that you built, send a note to gcc@gcc.gnu.org indicating ! that you successfully built and installed GCC. Include the following information: ! !

!

We'd also like to know if the host/target specific installation notes ! didn't include your host/target information or if that information is incomplete or out of date. Send a note to gcc@gcc.gnu.org detailing how the information should be changed. ! !

If you find a bug, please report it following the bug reporting guidelines. ! !

If you want to print the GCC manuals, do ‘cd objdir; make ! dvi’. You will need to have texi2dvi (version at least 4.7) ! and TeX installed. This creates a number of .dvi files in subdirectories of objdir; these may be converted for ! printing with programs such as dvips. Alternately, by using ! ‘make pdf’ in place of ‘make dvi’, you can create documentation ! in the form of .pdf files; this requires texi2pdf, which is included with Texinfo version 4.8 and later. You can also ! buy printed manuals from the Free Software Foundation, though such manuals may not be for the most recent version of GCC. -

If you would like to generate online HTML documentation, do ‘cd - objdir; make html’ and HTML will be generated for the gcc manuals in - objdir/gcc/HTML. -

    4. VERBATIM COPYING !

      You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other *************** technical measures to obstruct or contro *** 176,262 **** copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3. ! !

      You may also lend copies, under the same conditions stated above, and you may publicly display copies. !

    5. COPYING IN QUANTITY ! !

      If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the ! Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and ! visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects. ! !

      If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages. ! !

      If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols ! a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public. ! !

      It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document. !

    6. MODIFICATIONS ! !

      You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version: ! !

        !
      1. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. !
      2. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. !
      3. State on the Title page the name of the publisher of the Modified Version, as the publisher. !
      4. Preserve all the copyright notices of the Document. !
      5. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. !
      6. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below. !
      7. Preserve in that license notice the full lists of Invariant Sections ! and required Cover Texts given in the Document's license notice. !
      8. Include an unaltered copy of this License. !
      9. Preserve the section Entitled “History”, Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled “History” in the Document, create one --- 227,313 ---- copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3. !

        !

        You may also lend copies, under the same conditions stated above, and you may publicly display copies. +

        +
      11. MODIFICATIONS !

        You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version: !

        !
          !
        1. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. !
        2. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. !
        3. State on the Title page the name of the publisher of the Modified Version, as the publisher. !
        4. Preserve all the copyright notices of the Document. !
        5. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. !
        6. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below. !
        7. Preserve in that license notice the full lists of Invariant Sections ! and required Cover Texts given in the Document’s license notice. !
        8. Include an unaltered copy of this License. !
        9. Preserve the section Entitled “History”, Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled “History” in the Document, create one *************** stating the title, year, authors, and pu *** 264,309 **** given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. !
        10. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions ! it was based on. These may be placed in the “History” section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. !
        11. For any section Entitled “Acknowledgements” or “Dedications”, Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. !
        12. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles. !
        13. Delete any section Entitled “Endorsements”. Such a section may not be included in the Modified Version. !
        14. Do not retitle any existing section to be Entitled “Endorsements” or to conflict in title with any Invariant Section. !
        15. Preserve any Warranty Disclaimers. !
        !

        If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the ! list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles. ! !

        You may add a section Entitled “Endorsements”, provided it contains nothing but endorsements of your Modified Version by various parties—for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard. ! !

        You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or --- 315,360 ---- given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. !

      12. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions ! it was based on. These may be placed in the “History” section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. !
      13. For any section Entitled “Acknowledgements” or “Dedications”, Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. !

      The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version. !

    7. COMBINING DOCUMENTS ! !

      You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers. ! !

      The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original ! author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. ! !

      In the combination, you must combine any sections Entitled “History” in the various original documents, forming one section Entitled “History”; likewise combine any sections Entitled “Acknowledgements”, and any sections Entitled “Dedications”. You must delete all sections Entitled “Endorsements.” !

    8. COLLECTIONS OF DOCUMENTS ! !

      You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects. ! !

      You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document. !

    9. AGGREGATION WITH INDEPENDENT WORKS ! !

      A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an “aggregate” if the copyright resulting from the compilation is not used to limit the legal rights ! of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document. ! !

      If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of ! the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the ! electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate. !

    10. TRANSLATION ! !

      Translation is considered a kind of modification, so you may ! distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the --- 363,433 ---- by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one. !

    14. TRANSLATION !

      Translation is considered a kind of modification, so you may ! distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the *************** the original English version of this Lic *** 387,434 **** of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail. ! !

      If a section in the Document is Entitled “Acknowledgements”, “Dedications”, or “History”, the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title. !

    15. TERMINATION ! !

      You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License. ! !

Old installation documentation

!

Note most of this information is out of date and superseded by the previous chapters of this manual. It is provided for historical reference only, because of a lack of volunteers to merge it into the main manual. !

Here is the procedure for installing GCC on a GNU or Unix system. ! !

    !
  1. If you have chosen a configuration for GCC which requires other GNU tools (such as GAS or the GNU linker) instead of the standard system tools, install the required tools in the build directory under the names ! as, ld or whatever is appropriate. !

    Alternatively, you can do subsequent compilation using a value of the PATH environment variable such that the necessary GNU tools come before the standard system tools. !

  2. Specify the host, build and target machine configurations. You do this ! when you run the configure script. ! !

    The build machine is the system which you are using, the ! host machine is the system where you want to run the resulting ! compiler (normally the build machine), and the target machine is the system for which you want the compiler to generate code. ! !

    If you are building a compiler to produce code for the machine it runs on (a native compiler), you normally do not need to specify any operands ! to configure; it will try to guess the type of machine you are on ! and use that as the build, host and target machines. So you don't need to specify a configuration when building a native compiler unless ! configure cannot figure out what your configuration is or guesses wrong. ! !

    In those cases, specify the build machine's configuration name ! with the --host option; the host and target will default to be the same as the host machine. !

    Here is an example: ! ! 

              ./configure --host=sparc-sun-sunos4.1
!
    !

    A configuration name may be canonical or it may be more or less abbreviated. ! !

    A canonical configuration name has three parts, separated by dashes. ! It looks like this: ‘cpu-company-system’. ! (The three parts may themselves contain dashes; configure can figure out which dashes serve which purpose.) For example, ! ‘m68k-sun-sunos4.1’ specifies a Sun 3. ! !

    You can also replace parts of the configuration by nicknames or aliases. ! For example, ‘sun3’ stands for ‘m68k-sun’, so ! ‘sun3-sunos4.1’ is another way to specify a Sun 3. ! !

    You can specify a version number after any of the system types, and some of the CPU types. In most cases, the version is irrelevant, and will be ignored. So you might as well specify the version if you know it. ! !

    See Configurations, for a list of supported configuration names and notes on many of the configurations. You should check the notes in that section before proceeding any further with the installation of GCC. !

! !

Configurations Supported by GCC

! Here are the possible CPU types: !
! ! 1750a, a29k, alpha, arm, avr, cn, clipper, dsp16xx, elxsi, fr30, h8300, hppa1.0, hppa1.1, i370, i386, i486, i586, i686, i786, i860, i960, ip2k, m32r, m68000, m68k, m88k, mcore, mips, mipsel, mips64, mips64el, mn10200, mn10300, ns32k, pdp11, powerpc, powerpcle, romp, rs6000, sh, sparc, ! sparclite, sparc64, v850, vax, we32k. !
!

Here are the recognized company names. As you can see, customary abbreviations are used rather than the longer official names. ! ! !

! acorn, alliant, altos, apollo, apple, att, bull, cbm, convergent, convex, crds, dec, dg, dolphin, elxsi, encore, harris, hitachi, hp, ibm, intergraph, isi, mips, motorola, ncr, next, ns, omron, plexus, ! sequent, sgi, sony, sun, tti, unicom, wrs. !
!

The company name is meaningful only to disambiguate when the rest of the information supplied is insufficient. You can omit it, writing ! just ‘cpu-system’, if it is not needed. For example, ! ‘vax-ultrix4.2’ is equivalent to ‘vax-dec-ultrix4.2’. ! !

!

You can omit the system type; then configure guesses the operating system from the CPU and company. ! !

You can add a version number to the system type; this may or may not ! make a difference. For example, you can write ‘bsd4.3’ or ! ‘bsd4.4’ to distinguish versions of BSD. In practice, the version ! number is most needed for ‘sysv3’ and ‘sysv4’, which are often treated differently. ! !

‘linux-gnu’ is the canonical name for the GNU/Linux target; however ! GCC will also accept ‘linux’. The version of the kernel in use is ! not relevant on these systems. A suffix such as ‘libc1’ or ‘aout’ distinguishes major versions of the C library; all of the suffixed versions are obsolete. ! !

If you specify an impossible combination such as ‘i860-dg-vms’, ! then you may get an error message from configure, or it may ! ignore part of the information and do the best it can with the rest. ! configure always prints the canonical name for the alternative that it used. GCC does not support all possible alternatives. ! !

Often a particular model of machine has a name. Many machine names are recognized as aliases for CPU/company combinations. Thus, the machine ! name ‘sun3’, mentioned above, is an alias for ‘m68k-sun’. Sometimes we accept a company name as a machine name, when the name is popularly used for a particular machine. Here is a table of the known machine names: ! !

Old installation documentation

!

Note most of this information is out of date and superseded by the previous chapters of this manual. It is provided for historical reference only, because of a lack of volunteers to merge it into the main manual. +

!

Here is the procedure for installing GCC on a GNU or Unix system. !

!
    !
  1. If you have chosen a configuration for GCC which requires other GNU tools (such as GAS or the GNU linker) instead of the standard system tools, install the required tools in the build directory under the names ! as, ld or whatever is appropriate. !

    Alternatively, you can do subsequent compilation using a value of the PATH environment variable such that the necessary GNU tools come before the standard system tools. +

    +
  2. Specify the host, build and target machine configurations. You do this + when you run the configure script. !

    The build machine is the system which you are using, the ! host machine is the system where you want to run the resulting ! compiler (normally the build machine), and the target machine is the system for which you want the compiler to generate code. !

    !

    If you are building a compiler to produce code for the machine it runs on (a native compiler), you normally do not need to specify any operands ! to configure; it will try to guess the type of machine you are on ! and use that as the build, host and target machines. So you don’t need to specify a configuration when building a native compiler unless ! configure cannot figure out what your configuration is or guesses wrong. !

    !

    In those cases, specify the build machine’s configuration name ! with the --host option; the host and target will default to be the same as the host machine. +

    +

    Here is an example: +

    +
    + 
    ./configure --host=sparc-sun-sunos4.1
+
    !

    A configuration name may be canonical or it may be more or less abbreviated. !

    !

    A canonical configuration name has three parts, separated by dashes. ! It looks like this: ‘cpu-company-system’. ! (The three parts may themselves contain dashes; configure can figure out which dashes serve which purpose.) For example, ! ‘m68k-sun-sunos4.1’ specifies a Sun 3. !

    !

    You can also replace parts of the configuration by nicknames or aliases. ! For example, ‘sun3’ stands for ‘m68k-sun’, so ! ‘sun3-sunos4.1’ is another way to specify a Sun 3. !

    !

    You can specify a version number after any of the system types, and some of the CPU types. In most cases, the version is irrelevant, and will be ignored. So you might as well specify the version if you know it. !

    !

    See Configurations, for a list of supported configuration names and notes on many of the configurations. You should check the notes in that section before proceeding any further with the installation of GCC. +

Configurations Supported by GCC

!

Here are the possible CPU types: !

!
!

1750a, a29k, alpha, arm, avr, cn, clipper, dsp16xx, elxsi, fr30, h8300, hppa1.0, hppa1.1, i370, i386, i486, i586, i686, i786, i860, i960, ip2k, m32r, m68000, m68k, m88k, mcore, mips, mipsel, mips64, mips64el, mn10200, mn10300, ns32k, pdp11, powerpc, powerpcle, romp, rs6000, sh, sparc, ! sparclite, sparc64, v850, vax, we32k. !

Prerequisites for GCC

- - GCC requires that various tools and packages be available for use in the - build procedure. Modifying GCC sources requires additional tools - described below. !

Tools/packages necessary for building GCC

!
!
ISO C++98 compiler
Necessary to bootstrap GCC, although versions of GCC prior to 4.8 also allow bootstrapping with a ISO C89 compiler and versions of GCC prior to 3.4 also allow bootstrapping with a traditional (K&R) C compiler. ! !

To build all languages in a cross-compiler or other configuration where 3-stage bootstrap is not performed, you need to start with an existing GCC binary (version 3.4 or later) because source code for language frontends other than C might use GCC extensions. ! !

Note that to bootstrap GCC with versions of GCC earlier than 3.4, you ! may need to use --disable-stage1-checking, though bootstrapping the compiler with such earlier compilers is strongly discouraged. ! !

GNAT
! In order to build the Ada compiler (GNAT) you must already have GNAT installed because portions of the Ada frontend are written in Ada (with GNAT extensions.) Refer to the Ada installation instructions for more specific information. ! !
A “working” POSIX compatible shell, or GNU bash
! Necessary when running configure because some ! /bin/sh shells have bugs and may crash when configuring the ! target libraries. In other cases, /bin/sh or ksh have disastrous corner-case performance problems. This ! can cause target configure runs to literally take days to complete in some cases. ! !

So on some platforms /bin/ksh is sufficient, on others it ! isn't. See the host/target specific instructions for your platform, or ! use bash to be sure. Then set CONFIG_SHELL in your environment to your “good” shell prior to running ! configure/make. ! !

zsh is not a fully compliant POSIX shell and will not work when configuring GCC. ! !

A POSIX or SVR4 awk
! Necessary for creating some of the generated source files for GCC. If in doubt, use a recent GNU awk version, as some of the older ones are broken. GNU awk version 3.1.5 is known to work. ! !
GNU binutils
! Necessary in some circumstances, optional in others. See the host/target specific instructions for your platform for the exact requirements. ! !
gzip version 1.2.4 (or later) or
bzip2 version 1.0.2 (or later)
! Necessary to uncompress GCC tar files when source code is obtained via FTP mirror sites. ! !
GNU make version 3.80 (or later)
! You must have GNU make installed to build GCC. ! !
GNU tar version 1.14 (or later)
! Necessary (only on some platforms) to untar the source code. Many ! systems' tar programs will also work, only try GNU ! tar if you have problems. ! !
Perl version 5.6.1 (or later)
! Necessary when targeting Darwin, building ‘libstdc++’, ! and not using --disable-symvers. ! Necessary when targeting Solaris 2 with Sun ld and not using ! --disable-symvers. The bundled perl in Solaris 8 and up works. ! !

Necessary when regenerating Makefile dependencies in libiberty. ! Necessary when regenerating libiberty/functions.texi. ! Necessary when generating manpages from Texinfo manuals. Used by various scripts to generate some files included in SVN (mainly Unicode-related and rarely changing) from source tables. ! !

jar, or InfoZIP (zip and unzip)
! Necessary to build libgcj, the GCJ runtime. !
!

Several support libraries are necessary to build GCC, some are required, others optional. While any sufficiently new version of required tools usually work, library requirements are generally stricter. Newer ! versions may work in some cases, but it's safer to use the exact versions documented. We appreciate bug reports about problems with newer versions, though. If your OS vendor provides packages for the support libraries then using those packages may be the simplest way to install the libraries. ! !

!
GNU Multiple Precision Library (GMP) version 4.3.2 (or later)
! Necessary to build GCC. If a GMP source distribution is found in a ! subdirectory of your GCC sources named gmp, it will be built together with GCC. Alternatively, if GMP is already installed but it is not in your library search path, you will have to configure with the ! --with-gmp configure option. See also --with-gmp-lib ! and --with-gmp-include. ! !
MPFR Library version 2.4.2 (or later)
! Necessary to build GCC. It can be downloaded from http://www.mpfr.org/. If an MPFR source distribution is found ! in a subdirectory of your GCC sources named mpfr, it will be built together with GCC. Alternatively, if MPFR is already installed but it is not in your default library search path, the ! --with-mpfr configure option should be used. See also ! --with-mpfr-lib and --with-mpfr-include. ! !
MPC Library version 0.8.1 (or later)
! Necessary to build GCC. It can be downloaded from http://www.multiprecision.org/. If an MPC source distribution ! is found in a subdirectory of your GCC sources named mpc, it will be built together with GCC. Alternatively, if MPC is already installed but it is not in your default library search path, the ! --with-mpc configure option should be used. See also ! --with-mpc-lib and --with-mpc-include. ! !
ISL Library version 0.11.1
! Necessary to build GCC with the Graphite loop optimizations. It can be downloaded from ftp://gcc.gnu.org/pub/gcc/infrastructure/ ! as isl-0.11.1.tar.bz2. ! !

The --with-isl configure option should be used if ISL is not installed in your default library search path. ! !

CLooG 0.18.0
! Necessary to build GCC with the Graphite loop optimizations. It can be downloaded from ftp://gcc.gnu.org/pub/gcc/infrastructure/ as ! cloog-0.18.0.tar.gz. The --with-cloog configure option should ! be used if CLooG is not installed in your default library search path. ! CLooG needs to be built against ISL 0.11.1. Use --with-isl=system to direct CLooG to pick up an already installed ISL, otherwise it will use ISL 0.11.1 as bundled with CLooG. CLooG needs to be configured to use GMP ! internally, use --with-bits=gmp to direct it to do that. ! !
! !

Tools/packages necessary for modifying GCC

! !
!
autoconf version 2.64
GNU m4 version 1.4.6 (or later)
! Necessary when modifying configure.ac, aclocal.m4, etc. ! to regenerate configure and config.in files. ! !
automake version 1.11.1
! Necessary when modifying a Makefile.am file to regenerate its ! associated Makefile.in. !

Much of GCC does not use automake, so directly edit the Makefile.in ! file. Specifically this applies to the gcc, intl, ! libcpp, libiberty, libobjc directories as well as any of their subdirectories. ! !

For directories that use automake, GCC requires the latest release in the 1.11 series, which is currently 1.11.1. When regenerating a directory to a newer version, please update all the directories using an older 1.11 to the latest released version. ! !

gettext version 0.14.5 (or later)
! Needed to regenerate gcc.pot. ! !
gperf version 2.7.2 (or later)
! Necessary when modifying gperf input files, e.g. ! gcc/cp/cfns.gperf to regenerate its associated header file, e.g. ! gcc/cp/cfns.h. ! !
DejaGnu 1.4.4

Texinfo version 4.7 (or later)
! Necessary for running makeinfo when modifying *.texi files to test your changes. ! !

Necessary for running make dvi or make pdf to create printable documentation in DVI or PDF format. Texinfo version ! 4.8 or later is required for make pdf. ! !

Necessary to build GCC documentation during development because the generated output files are not included in the SVN repository. They are included in releases. ! !

TeX (any working version)
! Necessary for running texi2dvi and texi2pdf, which ! are used when running make dvi or make pdf to create DVI or PDF files, respectively. ! !
SVN (any version)
SSH (any version)

GNU diffutils version 2.7 (or later)
! Useful when submitting patches for the GCC source code. ! !
patch version 2.5.4 (or later)
! Necessary when applying patches, created with diff, to one's own sources. ! !
ecj1
gjavah
! If you wish to modify .java files in libjava, you will need to ! configure with --enable-java-maintainer-mode, and you will need ! to have executables named ecj1 and gjavah in your path. ! The ecj1 executable should run the Eclipse Java compiler via the GCC-specific entry point. You can download a suitable jar from ftp://sourceware.org/pub/java/, or by running the script ! contrib/download_ecj. ! !
antlr.jar version 2.7.1 (or later)
antlr binary
! If you wish to build the gjdoc binary in libjava, you will ! need to have an antlr.jar library available. The library is searched for in system locations but can be specified with ! --with-antlr-jar= instead. When configuring with ! --enable-java-maintainer-mode, you will need to have one of ! the executables named cantlr, runantlr or ! antlr in your path. !

*-*-freebsd*

Support for FreeBSD 1 was discontinued in GCC 3.2. Support for FreeBSD 2 (and any mutant a.out variants of FreeBSD 3) was discontinued in GCC 4.0. ! !

In order to better utilize FreeBSD base system functionality and match the configuration of the system compiler, GCC 4.5 and above as well as GCC 4.4 past 2010-06-20 leverage SSP support in libc (which is present on FreeBSD 7 or later) and the use of __cxa_atexit by default (on FreeBSD 6 or later). The use of dl_iterate_phdr inside ! libgcc_s.so.1 and boehm-gc (on FreeBSD 7 or later) is enabled by GCC 4.5 and above. ! !

We support FreeBSD using the ELF file format with DWARF 2 debugging ! for all CPU architectures. You may use -gstabs instead of ! -g, if you really want the old debugging format. There are no known issues with mixing object files and libraries with different debugging formats. Otherwise, this release of GCC should now match more of the configuration used in the stock FreeBSD configuration of ! GCC. In particular, --enable-threads is now configured by default. However, as a general user, do not attempt to replace the system compiler with this release. Known to bootstrap and check with good results on FreeBSD 7.2-STABLE. In the past, known to bootstrap and check with good results on FreeBSD 3.0, 3.4, 4.0, 4.2, 4.3, 4.4, 4.5, 4.8, 4.9 and 5-CURRENT. ! !

The version of binutils installed in /usr/bin probably works with this release of GCC. Bootstrapping against the latest GNU ! binutils and/or the version found in /usr/ports/devel/binutils has been known to enable additional features and improve overall testsuite results. However, it is currently known that boehm-gc (which itself is required for java) may not configure properly on FreeBSD prior to the FreeBSD 7.0 release with GNU binutils after 2.16.1. ! !

Please have a look at the binaries page. ! !

The calling convention and structure layout has changed in release 2.6. All code must be recompiled. The calling convention now passes the first three arguments in function calls in registers. Structures are no longer a multiple of 2 bytes. ! !

! !

hppa*-hp-hpux*

!

Support for HP-UX version 9 and older was discontinued in GCC 3.4. ! !

We require using gas/binutils on all hppa platforms. Version 2.19 or later is recommended. ! !

It may be helpful to configure GCC with the ! --with-gnu-as and ! --with-as=... options to ensure that GCC can find GAS. ! !

The HP assembler should not be used with GCC. It is rarely tested and may ! not work. It shouldn't be used with any languages other than C due to its many limitations. ! !

Specifically, -g does not work (HP-UX uses a peculiar debugging format which GCC does not know about). It also inserts timestamps into each object file it creates, causing the 3-stage comparison test to fail during a bootstrap. You should be able to continue by saying ! ‘make all-host all-target’ after getting the failure from ‘make’. ! !

Various GCC features are not supported. For example, it does not support weak symbols or alias definitions. As a result, explicit template instantiations are required when using C++. This makes it difficult if not impossible to build many C++ applications. ! !

There are two default scheduling models for instructions. These are PROCESSOR_7100LC and PROCESSOR_8000. They are selected from the pa-risc ! architecture specified for the target machine when configuring. PROCESSOR_8000 is the default. PROCESSOR_7100LC is selected when ! the target is a ‘hppa1*’ machine. ! !

The PROCESSOR_8000 model is not well suited to older processors. Thus, it is important to completely specify the machine architecture when configuring if you want a model other than PROCESSOR_8000. The macro TARGET_SCHED_DEFAULT can be defined in BOOT_CFLAGS if a different default scheduling model is desired. ! !

As of GCC 4.0, GCC uses the UNIX 95 namespace for HP-UX 10.10 ! through 11.00, and the UNIX 98 namespace for HP-UX 11.11 and later. This namespace change might cause problems when bootstrapping with an earlier version of GCC or the HP compiler as essentially the same namespace is required for an entire build. This problem can be avoided ! in a number of ways. With HP cc, UNIX_STD can be set to ‘95’ ! or ‘98’. Another way is to add an appropriate set of predefines ! to CC. The description for the munix= option contains a list of the predefines used with each standard. ! !

More specific information to ‘hppa*-hp-hpux*’ targets follows. ! !

! !

hppa*-hp-hpux10

For hpux10.20, we highly recommend you pick up the latest sed patch PHCO_19798 from HP. ! !

The C++ ABI has changed incompatibly in GCC 4.0. COMDAT subspaces are used for one-only code and data. This resolves many of the previous problems in using C++ on this target. However, the ABI is not compatible with the one implemented under HP-UX 11 using secondary definitions. ! !

! !

hppa*-hp-hpux11

GCC 3.0 and up support HP-UX 11. GCC 2.95.x is not supported and cannot be used to compile GCC 3.0 and up. ! !

The libffi and libjava libraries haven't been ported to 64-bit HP-UX and don't build. ! !

Refer to binaries for information about obtaining precompiled GCC binaries for HP-UX. Precompiled binaries must be obtained ! to build the Ada language as it can't be bootstrapped using C. Ada is only available for the 32-bit PA-RISC runtime. ! !

Starting with GCC 3.4 an ISO C compiler is required to bootstrap. The ! bundled compiler supports only traditional C; you will need either HP's unbundled compiler, or a binary distribution of GCC. ! !

It is possible to build GCC 3.3 starting with the bundled HP compiler, but the process requires several steps. GCC 3.3 can then be used to build later versions. The fastjar program contains ISO C code and ! can't be built with the HP bundled compiler. This problem can be avoided by not building the Java language. For example, use the ! --enable-languages="c,c++,f77,objc" option in your configure command. ! !

There are several possible approaches to building the distribution. Binutils can be built first using the HP tools. Then, the GCC distribution can be built. The second approach is to build GCC ! first using the HP tools, then build binutils, then rebuild GCC. There have been problems with various binary distributions, so it is best not to start from a binary distribution. ! !

On 64-bit capable systems, there are two distinct targets. Different installation prefixes must be used if both are to be installed on ! the same system. The ‘hppa[1-2]*-hp-hpux11*’ target generates code ! for the 32-bit PA-RISC runtime architecture and uses the HP linker. ! The ‘hppa64-hp-hpux11*’ target generates 64-bit code for the PA-RISC 2.0 architecture. ! !

The script config.guess now selects the target type based on the compiler ! detected during configuration. You must define PATH or CC so ! that configure finds an appropriate compiler for the initial bootstrap. ! When CC is used, the definition should contain the options that are ! needed whenever CC is used. ! !

Specifically, options that determine the runtime architecture must be ! in CC to correctly select the target for the build. It is also ! convenient to place many other compiler options in CC. For example, ! CC="cc -Ac +DA2.0W -Wp,-H16376 -D_CLASSIC_TYPES -D_HPUX_SOURCE" can be used to bootstrap the GCC 3.3 branch with the HP compiler in ! 64-bit K&R/bundled mode. The +DA2.0W option will result in ! the automatic selection of the ‘hppa64-hp-hpux11*’ target. The macro definition table of cpp needs to be increased for a successful build with the HP compiler. _CLASSIC_TYPES and _HPUX_SOURCE need to be defined when building with the bundled compiler, or when using the ! -Ac option. These defines aren't necessary with -Ae. ! !

It is best to explicitly configure the ‘hppa64-hp-hpux11*’ target ! with the --with-ld=... option. This overrides the standard search for ld. The two linkers supported on this target require different commands. The default linker is determined during configuration. As a ! result, it's not possible to switch linkers in the middle of a GCC build. This has been reported to sometimes occur in unified builds of binutils and GCC. ! !

A recent linker patch must be installed for the correct operation of GCC 3.3 and later. PHSS_26559 and PHSS_24304 are the oldest linker patches that are known to work. They are for HP-UX 11.00 and 11.11, respectively. PHSS_24303, the companion to ! PHSS_24304, might be usable but it hasn't been tested. These patches have been superseded. Consult the HP patch database to obtain the currently recommended linker patch for your system. ! !

The patches are necessary for the support of weak symbols on the 32-bit port, and for the running of initializers and finalizers. Weak symbols are implemented using SOM secondary definition symbols. Prior ! to HP-UX 11, there are bugs in the linker support for secondary symbols. The patches correct a problem of linker core dumps creating shared libraries containing secondary symbols, as well as various other linking issues involving secondary symbols. ! !

GCC 3.3 uses the ELF DT_INIT_ARRAY and DT_FINI_ARRAY capabilities to run initializers and finalizers on the 64-bit port. The 32-bit port ! uses the linker +init and +fini options for the same purpose. The patches correct various problems with the +init/+fini options, including program core dumps. Binutils 2.14 corrects a ! problem on the 64-bit port resulting from HP's non-standard use of the .init and .fini sections for array initializers and finalizers. ! !

Although the HP and GNU linkers are both supported for the ! ‘hppa64-hp-hpux11*’ target, it is strongly recommended that the HP linker be used for link editing on this target. ! !

At this time, the GNU linker does not support the creation of long ! branch stubs. As a result, it can't successfully link binaries containing branch offsets larger than 8 megabytes. In addition, there are problems linking shared libraries, linking executables ! with -static, and with dwarf2 unwind and exception support. ! It also doesn't provide stubs for internal calls to global functions ! in shared libraries, so these calls can't be overloaded. ! !

The HP dynamic loader does not support GNU symbol versioning, so symbol versioning is not supported. It may be necessary to disable symbol ! versioning with --disable-symvers when using GNU ld. ! !

POSIX threads are the default. The optional DCE thread library is not ! supported, so --enable-threads=dce does not work. ! !

! !

*-*-linux-gnu

Versions of libstdc++-v3 starting with 3.2.1 require bug fixes present in glibc 2.2.5 and later. More information is available in the libstdc++-v3 documentation. !

! !

i?86-*-linux*

! !

As of GCC 3.3, binutils 2.13.1 or later is required for this platform. See bug 10877 for more information. ! !

If you receive Signal 11 errors when building on GNU/Linux, then it is possible you have a hardware problem. Further information on this can be found on www.bitwizard.nl. ! !

! !

i?86-*-solaris2.9

! !

The Sun assembler in Solaris 9 has several bugs and limitations. While GCC works around them, several features are missing, so it is - recommended to use the GNU assembler instead. There is no bundled version, but the current version, from GNU binutils 2.22, is known to work. ! !

Solaris 2/x86 doesn't support the execution of SSE/SSE2 instructions before Solaris 9 4/04, even if the CPU supports them. Programs will receive SIGILL if they try. The fix is available both in Solaris 9 Update 6 and kernel patch 112234-12 or newer. To avoid this problem, ! -march defaults to ‘pentiumpro’ on Solaris 9. If you have the patch installed, you can configure GCC with an appropriate ! --with-arch option, but need GNU as for SSE2 support. ! !

! !

i?86-*-solaris2.10

!

Use this for Solaris 10 or later on x86 and x86-64 systems. Starting ! with GCC 4.7, there is also a 64-bit ‘amd64-*-solaris2.1[0-9]*’ or ! ‘x86_64-*-solaris2.1[0-9]*’ configuration that corresponds to ! ‘sparcv9-sun-solaris2*’. ! !

It is recommended that you configure GCC to use the GNU assembler, in ! /usr/sfw/bin/gas. The versions included in Solaris 10, from GNU binutils 2.15, and Solaris 11, from GNU binutils 2.19, work fine, although the current version, from GNU binutils 2.22, is known to work, too. Recent versions of the Sun assembler in ! /usr/ccs/bin/as work almost as well, though. ! ! !

For linking, the Sun linker, is preferred. If you want to use the GNU ! linker instead, which is available in /usr/sfw/bin/gld, note that due to a packaging bug the version in Solaris 10, from GNU binutils 2.15, cannot be used, while the version in Solaris 11, from GNU binutils 2.19, works, as does the latest version, from GNU binutils 2.22. ! !

To use GNU as, configure with the options ! --with-gnu-as --with-as=/usr/sfw/bin/gas. It may be necessary ! to configure with --without-gnu-ld --with-ld=/usr/ccs/bin/ld to ! guarantee use of Sun ld. ! ! !

! !

ia64-*-linux

!

IA-64 processor (also known as IPF, or Itanium Processor Family) running GNU/Linux. ! !

If you are using the installed system libunwind library with ! --with-system-libunwind, then you must use libunwind 0.98 or later. ! !

None of the following versions of GCC has an ABI that is compatible with any of the other versions in this list, with the exception that Red Hat 2.96 and Trillian 000171 are compatible with each other: ! 3.1, 3.0.2, 3.0.1, 3.0, Red Hat 2.96, and Trillian 000717. ! This primarily affects C++ programs and programs that create shared libraries. ! GCC 3.1 or later is recommended for compiling linux, the kernel. As of version 3.1 GCC is believed to be fully ABI compliant, and hence no more major ABI changes are expected. ! !

! !

ia64-*-hpux*

!

Building GCC on this target requires the GNU Assembler. The bundled HP assembler will not work. To prevent GCC from using the wrong assembler, ! the option --with-gnu-as may be necessary. ! !

The GCC libunwind library has not been ported to HPUX. This means that for ! GCC versions 3.2.3 and earlier, --enable-libunwind-exceptions ! is required to build GCC. For GCC 3.3 and later, this is the default. ! For gcc 3.4.3 and later, --enable-libunwind-exceptions is removed and the system libunwind library will always be used. ! !

! ! !

*-ibm-aix*

! !

Support for AIX version 3 and older was discontinued in GCC 3.4. Support for AIX version 4.2 and older was discontinued in GCC 4.5. ! !

“out of memory” bootstrap failures may indicate a problem with process resource limits (ulimit). Hard limits are configured in the ! /etc/security/limits system configuration file. ! !

GCC can bootstrap with recent versions of IBM XLC, but bootstrapping with an earlier release of GCC is recommended. Bootstrapping with XLC requires a larger data segment, which can be enabled through the LDR_CNTRL environment variable, e.g., ! 

     % LDR_CNTRL=MAXDATA=0x50000000
!      % export LDR_CNTRL
!
!

One can start with a pre-compiled version of GCC to build from ! sources. One may delete GCC's “fixed” header files when starting with a version of GCC built for an earlier release of AIX. !

To speed up the configuration phases of bootstrapping and installing GCC, ! one may use GNU Bash instead of AIX /bin/sh, e.g., ! ! 

     % CONFIG_SHELL=/opt/freeware/bin/bash
!      % export CONFIG_SHELL
!
!

and then proceed as described in the build instructions, where we strongly recommend specifying an absolute path to invoke srcdir/configure. ! !

Because GCC on AIX is built as a 32-bit executable by default, (although it can generate 64-bit programs) the GMP and MPFR libraries required by gfortran must be 32-bit libraries. Building GMP and MPFR as static archive libraries works better than shared libraries. ! !

Errors involving alloca when building GCC generally are due to an incorrect definition of CC in the Makefile or mixing files compiled with the native C compiler and GCC. During the stage1 phase of ! the build, the native AIX compiler must be invoked as cc ! (not xlc). Once configure has been informed of ! xlc, one needs to use ‘make distclean’ to remove the ! configure cache files and ensure that CC environment variable ! does not provide a definition that will confuse configure. If this error occurs during stage2 or later, then the problem most likely is the version of Make (see above). ! !

The native as and ld are recommended for bootstrapping on AIX. The GNU Assembler, GNU Linker, and GNU Binutils version 2.20 is the minimum level that supports bootstrap on ! AIX 5. The GNU Assembler has not been updated to support AIX 6 or AIX 7. The native AIX tools do interoperate with GCC. ! !

AIX 5.3 TL10, AIX 6.1 TL05 and AIX 7.1 TL00 introduced an AIX assembler change that sometimes produces corrupt assembly files causing AIX linker errors. The bug breaks GCC bootstrap on AIX and can cause compilation failures with existing GCC installations. An --- 1,675 ---- ! ! ! ! ! ! Installing GCC ! ! ! ! ! ! ! ! ! ! ! !

The version of binutils installed in /usr/bin probably works with this release of GCC. Bootstrapping against the latest GNU ! binutils and/or the version found in /usr/ports/devel/binutils has been known to enable additional features and improve overall testsuite results. However, it is currently known that boehm-gc (which itself is required for java) may not configure properly on FreeBSD prior to the FreeBSD 7.0 release with GNU binutils after 2.16.1. !

hppa*-hp-hpux*

Support for HP-UX version 9 and older was discontinued in GCC 3.4. !

!

We require using gas/binutils on all hppa platforms. Version 2.19 or later is recommended. !

!

It may be helpful to configure GCC with the ! --with-gnu-as and ! --with-as=… options to ensure that GCC can find GAS. !

!

The HP assembler should not be used with GCC. It is rarely tested and may ! not work. It shouldn’t be used with any languages other than C due to its many limitations. !

!

Specifically, -g does not work (HP-UX uses a peculiar debugging format which GCC does not know about). It also inserts timestamps into each object file it creates, causing the 3-stage comparison test to fail during a bootstrap. You should be able to continue by saying ! ‘make all-host all-target’ after getting the failure from ‘make’. !

!

Various GCC features are not supported. For example, it does not support weak symbols or alias definitions. As a result, explicit template instantiations are required when using C++. This makes it difficult if not impossible to build many C++ applications. !

!

There are two default scheduling models for instructions. These are PROCESSOR_7100LC and PROCESSOR_8000. They are selected from the pa-risc ! architecture specified for the target machine when configuring. PROCESSOR_8000 is the default. PROCESSOR_7100LC is selected when ! the target is a ‘hppa1*’ machine. !

!

The PROCESSOR_8000 model is not well suited to older processors. Thus, it is important to completely specify the machine architecture when configuring if you want a model other than PROCESSOR_8000. The macro TARGET_SCHED_DEFAULT can be defined in BOOT_CFLAGS if a different default scheduling model is desired. !

!

As of GCC 4.0, GCC uses the UNIX 95 namespace for HP-UX 10.10 ! through 11.00, and the UNIX 98 namespace for HP-UX 11.11 and later. This namespace change might cause problems when bootstrapping with an earlier version of GCC or the HP compiler as essentially the same namespace is required for an entire build. This problem can be avoided ! in a number of ways. With HP cc, UNIX_STD can be set to ‘95’ ! or ‘98’. Another way is to add an appropriate set of predefines ! to CC. The description for the munix= option contains a list of the predefines used with each standard. !

!

More specific information to ‘hppa*-hp-hpux*’ targets follows. !

!
!

hppa*-hp-hpux10

For hpux10.20, we highly recommend you pick up the latest sed patch PHCO_19798 from HP. !

!

The C++ ABI has changed incompatibly in GCC 4.0. COMDAT subspaces are used for one-only code and data. This resolves many of the previous problems in using C++ on this target. However, the ABI is not compatible with the one implemented under HP-UX 11 using secondary definitions. !

!
!

hppa*-hp-hpux11

GCC 3.0 and up support HP-UX 11. GCC 2.95.x is not supported and cannot be used to compile GCC 3.0 and up. !

!

The libffi and libjava libraries haven’t been ported to 64-bit HP-UX and don’t build. !

!

Refer to binaries for information about obtaining precompiled GCC binaries for HP-UX. Precompiled binaries must be obtained ! to build the Ada language as it can’t be bootstrapped using C. Ada is only available for the 32-bit PA-RISC runtime. !

!

Starting with GCC 3.4 an ISO C compiler is required to bootstrap. The ! bundled compiler supports only traditional C; you will need either HP’s unbundled compiler, or a binary distribution of GCC. !

!

It is possible to build GCC 3.3 starting with the bundled HP compiler, but the process requires several steps. GCC 3.3 can then be used to build later versions. The fastjar program contains ISO C code and ! can’t be built with the HP bundled compiler. This problem can be avoided by not building the Java language. For example, use the ! --enable-languages="c,c++,f77,objc" option in your configure command. !

!

There are several possible approaches to building the distribution. Binutils can be built first using the HP tools. Then, the GCC distribution can be built. The second approach is to build GCC ! first using the HP tools, then build binutils, then rebuild GCC. There have been problems with various binary distributions, so it is best not to start from a binary distribution. !

!

On 64-bit capable systems, there are two distinct targets. Different installation prefixes must be used if both are to be installed on ! the same system. The ‘hppa[1-2]*-hp-hpux11*’ target generates code ! for the 32-bit PA-RISC runtime architecture and uses the HP linker. ! The ‘hppa64-hp-hpux11*’ target generates 64-bit code for the PA-RISC 2.0 architecture. !

!

The script config.guess now selects the target type based on the compiler ! detected during configuration. You must define PATH or CC so ! that configure finds an appropriate compiler for the initial bootstrap. ! When CC is used, the definition should contain the options that are ! needed whenever CC is used. !

!

Specifically, options that determine the runtime architecture must be ! in CC to correctly select the target for the build. It is also ! convenient to place many other compiler options in CC. For example, ! CC="cc -Ac +DA2.0W -Wp,-H16376 -D_CLASSIC_TYPES -D_HPUX_SOURCE" can be used to bootstrap the GCC 3.3 branch with the HP compiler in ! 64-bit K&R/bundled mode. The +DA2.0W option will result in ! the automatic selection of the ‘hppa64-hp-hpux11*’ target. The macro definition table of cpp needs to be increased for a successful build with the HP compiler. _CLASSIC_TYPES and _HPUX_SOURCE need to be defined when building with the bundled compiler, or when using the ! -Ac option. These defines aren’t necessary with -Ae. !

!

It is best to explicitly configure the ‘hppa64-hp-hpux11*’ target ! with the --with-ld=… option. This overrides the standard search for ld. The two linkers supported on this target require different commands. The default linker is determined during configuration. As a ! result, it’s not possible to switch linkers in the middle of a GCC build. This has been reported to sometimes occur in unified builds of binutils and GCC. !

!

A recent linker patch must be installed for the correct operation of GCC 3.3 and later. PHSS_26559 and PHSS_24304 are the oldest linker patches that are known to work. They are for HP-UX 11.00 and 11.11, respectively. PHSS_24303, the companion to ! PHSS_24304, might be usable but it hasn’t been tested. These patches have been superseded. Consult the HP patch database to obtain the currently recommended linker patch for your system. !

!

The patches are necessary for the support of weak symbols on the 32-bit port, and for the running of initializers and finalizers. Weak symbols are implemented using SOM secondary definition symbols. Prior ! to HP-UX 11, there are bugs in the linker support for secondary symbols. The patches correct a problem of linker core dumps creating shared libraries containing secondary symbols, as well as various other linking issues involving secondary symbols. !

!

GCC 3.3 uses the ELF DT_INIT_ARRAY and DT_FINI_ARRAY capabilities to run initializers and finalizers on the 64-bit port. The 32-bit port ! uses the linker +init and +fini options for the same purpose. The patches correct various problems with the +init/+fini options, including program core dumps. Binutils 2.14 corrects a ! problem on the 64-bit port resulting from HP’s non-standard use of the .init and .fini sections for array initializers and finalizers. !

!

Although the HP and GNU linkers are both supported for the ! ‘hppa64-hp-hpux11*’ target, it is strongly recommended that the HP linker be used for link editing on this target. !

!

At this time, the GNU linker does not support the creation of long ! branch stubs. As a result, it can’t successfully link binaries containing branch offsets larger than 8 megabytes. In addition, there are problems linking shared libraries, linking executables ! with -static, and with dwarf2 unwind and exception support. ! It also doesn’t provide stubs for internal calls to global functions ! in shared libraries, so these calls can’t be overloaded. !

!

The HP dynamic loader does not support GNU symbol versioning, so symbol versioning is not supported. It may be necessary to disable symbol ! versioning with --disable-symvers when using GNU ld. !

!

POSIX threads are the default. The optional DCE thread library is not ! supported, so --enable-threads=dce does not work. !

!
!

*-*-linux-gnu

Versions of libstdc++-v3 starting with 3.2.1 require bug fixes present in glibc 2.2.5 and later. More information is available in the libstdc++-v3 documentation. +

+
+

i?86-*-linux*

!

As of GCC 3.3, binutils 2.13.1 or later is required for this platform. See bug 10877 for more information. !

!

If you receive Signal 11 errors when building on GNU/Linux, then it is possible you have a hardware problem. Further information on this can be found on www.bitwizard.nl. !

!
!

i?86-*-solaris2.9

!

The Sun assembler in Solaris 9 has several bugs and limitations. While GCC works around them, several features are missing, so it is recommended to use the GNU assembler instead. There is no bundled version, but the current version, from GNU binutils 2.22, is known to work. !

!

Solaris 2/x86 doesn’t support the execution of SSE/SSE2 instructions before Solaris 9 4/04, even if the CPU supports them. Programs will receive SIGILL if they try. The fix is available both in Solaris 9 Update 6 and kernel patch 112234-12 or newer. To avoid this problem, ! -march defaults to ‘pentiumpro’ on Solaris 9. If you have the patch installed, you can configure GCC with an appropriate ! --with-arch option, but need GNU as for SSE2 support. !

!
!

i?86-*-solaris2.10

Use this for Solaris 10 or later on x86 and x86-64 systems. Starting ! with GCC 4.7, there is also a 64-bit ‘amd64-*-solaris2.1[0-9]*’ or ! ‘x86_64-*-solaris2.1[0-9]*’ configuration that corresponds to ! ‘sparcv9-sun-solaris2*’. !

!

It is recommended that you configure GCC to use the GNU assembler, in ! /usr/sfw/bin/gas. The versions included in Solaris 10, from GNU binutils 2.15, and Solaris 11, from GNU binutils 2.19, work fine, although the current version, from GNU binutils 2.22, is known to work, too. Recent versions of the Sun assembler in ! /usr/ccs/bin/as work almost as well, though. !

!

For linking, the Sun linker, is preferred. If you want to use the GNU ! linker instead, which is available in /usr/sfw/bin/gld, note that due to a packaging bug the version in Solaris 10, from GNU binutils 2.15, cannot be used, while the version in Solaris 11, from GNU binutils 2.19, works, as does the latest version, from GNU binutils 2.22. !

!

To use GNU as, configure with the options ! --with-gnu-as --with-as=/usr/sfw/bin/gas. It may be necessary ! to configure with --without-gnu-ld --with-ld=/usr/ccs/bin/ld to ! guarantee use of Sun ld. !

!
!

ia64-*-linux

IA-64 processor (also known as IPF, or Itanium Processor Family) running GNU/Linux. !

!

If you are using the installed system libunwind library with ! --with-system-libunwind, then you must use libunwind 0.98 or later. !

!

None of the following versions of GCC has an ABI that is compatible with any of the other versions in this list, with the exception that Red Hat 2.96 and Trillian 000171 are compatible with each other: ! 3.1, 3.0.2, 3.0.1, 3.0, Red Hat 2.96, and Trillian 000717. ! This primarily affects C++ programs and programs that create shared libraries. ! GCC 3.1 or later is recommended for compiling linux, the kernel. As of version 3.1 GCC is believed to be fully ABI compliant, and hence no more major ABI changes are expected. !

!
!

ia64-*-hpux*

Building GCC on this target requires the GNU Assembler. The bundled HP assembler will not work. To prevent GCC from using the wrong assembler, ! the option --with-gnu-as may be necessary. !

!

The GCC libunwind library has not been ported to HPUX. This means that for ! GCC versions 3.2.3 and earlier, --enable-libunwind-exceptions ! is required to build GCC. For GCC 3.3 and later, this is the default. ! For gcc 3.4.3 and later, --enable-libunwind-exceptions is removed and the system libunwind library will always be used. !

!
! !

*-ibm-aix*

!

Support for AIX version 3 and older was discontinued in GCC 3.4. Support for AIX version 4.2 and older was discontinued in GCC 4.5. !

!

“out of memory” bootstrap failures may indicate a problem with process resource limits (ulimit). Hard limits are configured in the ! /etc/security/limits system configuration file. !

!

GCC can bootstrap with recent versions of IBM XLC, but bootstrapping with an earlier release of GCC is recommended. Bootstrapping with XLC requires a larger data segment, which can be enabled through the LDR_CNTRL environment variable, e.g., +

+
+ 
% LDR_CNTRL=MAXDATA=0x50000000
+ % export LDR_CNTRL
+
!

One can start with a pre-compiled version of GCC to build from ! sources. One may delete GCC’s “fixed” header files when starting with a version of GCC built for an earlier release of AIX. +

+

To speed up the configuration phases of bootstrapping and installing GCC, + one may use GNU Bash instead of AIX /bin/sh, e.g., +

+
+ 
% CONFIG_SHELL=/opt/freeware/bin/bash
+ % export CONFIG_SHELL
+
!

and then proceed as described in the build ! instructions, where we strongly recommend specifying an absolute path to invoke srcdir/configure. !

!

Because GCC on AIX is built as a 32-bit executable by default, (although it can generate 64-bit programs) the GMP and MPFR libraries required by gfortran must be 32-bit libraries. Building GMP and MPFR as static archive libraries works better than shared libraries. !

!

Errors involving alloca when building GCC generally are due to an incorrect definition of CC in the Makefile or mixing files compiled with the native C compiler and GCC. During the stage1 phase of ! the build, the native AIX compiler must be invoked as cc ! (not xlc). Once configure has been informed of ! xlc, one needs to use ‘make distclean’ to remove the ! configure cache files and ensure that CC environment variable ! does not provide a definition that will confuse configure. If this error occurs during stage2 or later, then the problem most likely is the version of Make (see above). !

!

The native as and ld are recommended for bootstrapping on AIX. The GNU Assembler, GNU Linker, and GNU Binutils version 2.20 is the minimum level that supports bootstrap on ! AIX 5. The GNU Assembler has not been updated to support AIX 6 or AIX 7. The native AIX tools do interoperate with GCC. !

!

AIX 5.3 TL10, AIX 6.1 TL05 and AIX 7.1 TL00 introduced an AIX assembler change that sometimes produces corrupt assembly files causing AIX linker errors. The bug breaks GCC bootstrap on AIX and can cause compilation failures with existing GCC installations. An *************** AIX iFix for AIX 5.3 is available (APAR *** 647,1441 **** IZ98477 for AIX 5.3 TL11 and IZ98134 for AIX 5.3 TL12). AIX 5.3 TL11 SP8, AIX 5.3 TL12 SP5, AIX 6.1 TL04 SP11, AIX 6.1 TL05 SP7, AIX 6.1 TL06 SP6, AIX 6.1 TL07 and AIX 7.1 TL01 should include the fix. ! !

Building libstdc++.a requires a fix for an AIX Assembler bug APAR IY26685 (AIX 4.3) or APAR IY25528 (AIX 5.1). It also requires a fix for another AIX Assembler bug and a co-dependent AIX Archiver fix referenced as APAR IY53606 (AIX 5.2) or as APAR IY54774 (AIX 5.1) ! !

‘libstdc++’ in GCC 3.4 increments the major version number of the ! shared object and GCC installation places the libstdc++.a shared library in a common location which will overwrite the and GCC 3.3 version of the shared library. Applications either need to be re-linked against the new shared library or the GCC 3.1 and GCC 3.3 ! versions of the ‘libstdc++’ shared object needs to be available ! to the AIX runtime loader. The GCC 3.1 ‘libstdc++.so.4’, if ! present, and GCC 3.3 ‘libstdc++.so.5’ shared objects can be installed for runtime dynamic loading using the following steps to set ! the ‘F_LOADONLY’ flag in the shared object for each ! multilib libstdc++.a installed: !

Extract the shared objects from the currently installed ! libstdc++.a archive: ! 

     % ar -x libstdc++.a libstdc++.so.4 libstdc++.so.5
!
!

Enable the ‘F_LOADONLY’ flag so that the shared object will be available for runtime dynamic loading, but not linking: ! 

     % strip -e libstdc++.so.4 libstdc++.so.5
!
!

Archive the runtime-only shared object in the GCC 3.4 ! libstdc++.a archive: ! 

     % ar -q libstdc++.a libstdc++.so.4 libstdc++.so.5
!
!

Linking executables and shared libraries may produce warnings of duplicate symbols. The assembly files generated by GCC for AIX always have included multiple symbol definitions for certain global variable and function declarations in the original program. The warnings should not prevent the linker from producing a correct library or runnable executable. ! !

AIX 4.3 utilizes a “large format” archive to support both 32-bit and 64-bit object modules. The routines provided in AIX 4.3.0 and AIX 4.3.1 ! to parse archive libraries did not handle the new format correctly. These routines are used by GCC and result in error messages during linking such as “not a COFF file”. The version of the routines shipped ! with AIX 4.3.1 should work for a 32-bit environment. The -g option of the archive command may be used to create archives of 32-bit objects using the original “small format”. A correct version of the routines is shipped with AIX 4.3.2 and above. ! !

Some versions of the AIX binder (linker) can fail with a relocation ! overflow severe error when the -bbigtoc option is used to link GCC-produced object files into an executable that overflows the TOC. A fix for APAR IX75823 (OVERFLOW DURING LINK WHEN USING GCC AND -BBIGTOC) is available from IBM Customer Support and from its techsupport.services.ibm.com website as PTF U455193. ! !

The AIX 4.3.2.1 linker (bos.rte.bind_cmds Level 4.3.2.1) will dump core with a segmentation fault when invoked by any version of GCC. A fix for APAR IX87327 is available from IBM Customer Support and from its techsupport.services.ibm.com website as PTF U461879. This fix is incorporated in AIX 4.3.3 and above. ! !

The initial assembler shipped with AIX 4.3.0 generates incorrect object files. A fix for APAR IX74254 (64BIT DISASSEMBLED OUTPUT FROM COMPILER FAILS TO ASSEMBLE/BIND) is available from IBM Customer Support and from its techsupport.services.ibm.com website as PTF U453956. This fix is incorporated in AIX 4.3.1 and above. ! !

AIX provides National Language Support (NLS). Compilers and assemblers use NLS to support locale-specific representations of various data ! formats including floating-point numbers (e.g., ‘.’ vs ‘,’ for separating decimal fractions). There have been problems reported where GCC does not produce the same floating-point formats that the assembler ! expects. If one encounters this problem, set the LANG ! environment variable to ‘C’ or ‘En_US’. ! !

A default can be specified with the -mcpu=cpu_type ! switch and using the configure option --with-cpu-cpu_type. ! !

m68k-*-*

!

By default, ! ‘m68k-*-elf*’, ‘m68k-*-rtems’, ‘m68k-*-uclinux’ and ! ‘m68k-*-linux’ build libraries for both M680x0 and ColdFire processors. If you only need the M680x0 libraries, you can omit the ColdFire ones by passing ! --with-arch=m68k to configure. Alternatively, you ! can omit the M680x0 libraries by passing --with-arch=cf to ! configure. These targets default to 5206 or 5475 code as appropriate for the target system when ! configured with --with-arch=cf and 68020 code otherwise. ! !

The ‘m68k-*-netbsd’ and ! ‘m68k-*-openbsd’ targets also support the --with-arch option. They will generate ColdFire CFV4e code when configured with ! --with-arch=cf and 68020 code otherwise. ! !

You can override the default processors listed above by configuring ! with --with-cpu=target. This target can either ! be a -mcpu argument or one of the following values: ! ‘m68000’, ‘m68010’, ‘m68020’, ‘m68030’, ! ‘m68040’, ‘m68060’, ‘m68020-40’ and ‘m68020-60’. ! !

mips-*-*

!

If on a MIPS system you get an error message saying “does not have gp ! sections for all it's [sic] sectons [sic]”, don't worry about it. This happens whenever you use GAS with the MIPS linker, but there is not really anything wrong, and it is okay to use the output file. You can stop such warnings by installing the GNU linker. ! !

It would be nice to extend GAS to produce the gp tables, but they are optional, and there should not be a warning about their absence. ! !

The libstdc++ atomic locking routines for MIPS targets requires MIPS II and later. A patch went in just after the GCC 3.3 release to ! make ‘mips*-*-*’ use the generic implementation instead. You can also ! configure for ‘mipsel-elf’ as a workaround. The ! ‘mips*-*-linux*’ target continues to use the MIPS II routines. More work on this is expected in future releases. ! ! !

The built-in __sync_* functions are available on MIPS II and ! later systems and others that support the ‘ll’, ‘sc’ and ! ‘sync’ instructions. This can be overridden by passing ! --with-llsc or --without-llsc when configuring GCC. Since the Linux kernel emulates these instructions if they are ! missing, the default for ‘mips*-*-linux*’ targets is ! --with-llsc. The --with-llsc and ! --without-llsc configure options may be overridden at compile ! time by passing the -mllsc or -mno-llsc options to the compiler. ! !

MIPS systems check for division by zero (unless ! -mno-check-zero-division is passed to the compiler) by generating either a conditional trap or a break instruction. Using trap results in smaller code, but is only supported on MIPS II and later. Also, some versions of the Linux kernel have a bug that prevents trap from generating the proper signal (SIGFPE). To enable ! the use of break, use the --with-divide=breaks ! configure option when configuring GCC. The default is to use traps on systems that support them. ! !

The assembler from GNU binutils 2.17 and earlier has a bug in the way it sorts relocations for REL targets (o32, o64, EABI). This can cause bad code to be generated for simple C++ programs. Also the linker from GNU binutils versions prior to 2.17 has a bug which causes the ! runtime linker stubs in very large programs, like libgcj.so, to be incorrectly generated. GNU Binutils 2.18 and later (and snapshots made after Nov. 9, 2006) should be free from both of these problems. ! !

The Solaris 2 /bin/sh will often fail to configure ! ‘libstdc++-v3’, ‘boehm-gc’ or ‘libjava’. We therefore recommend using the following initial sequence of commands ! 

     % CONFIG_SHELL=/bin/ksh
!      % export CONFIG_SHELL
!
!

and proceed as described in the configure instructions. In addition we strongly recommend specifying an absolute path to invoke ! srcdir/configure. ! !

Solaris 2 comes with a number of optional OS packages. Some of these are needed to use GCC fully, namely SUNWarc, SUNWbtool, SUNWesu, SUNWhea, SUNWlibm, SUNWsprot, and SUNWtoo. If you did not install all optional packages when installing Solaris 2, you will need to verify that the packages that GCC needs are installed. ! !

To check whether an optional package is installed, use ! the pkginfo command. To add an optional package, use the ! pkgadd command. For further details, see the Solaris 2 documentation. ! !

Trying to use the linker and other tools in ! /usr/ucb to install GCC has been observed to cause trouble. For example, the linker may hang indefinitely. The fix is to remove ! /usr/ucb from your PATH. ! !

The build process works more smoothly with the legacy Sun tools so, if you ! have /usr/xpg4/bin in your PATH, we recommend that you place ! /usr/bin before /usr/xpg4/bin for the duration of the build. ! !

We recommend the use of the Sun assembler or the GNU assembler, in ! conjunction with the Sun linker. The GNU as versions included in Solaris 10, from GNU binutils 2.15, and Solaris 11, from GNU binutils 2.19, are known to work. They can be found in ! /usr/sfw/bin/gas. Current versions of GNU binutils (2.22) are known to work as well. Note that your mileage may vary if you use a combination of the GNU tools and the Sun tools: while the ! combination GNU as + Sun ld should reasonably work, ! the reverse combination Sun as + GNU ld may fail to ! build or cause memory corruption at runtime in some cases for C++ programs. ! ! GNU ld usually works as well, although the version included in Solaris 10 cannot be used due to several bugs. Again, the current version (2.22) is known to work, but generally lacks platform specific ! features, so better stay with Sun ld. To use the LTO linker ! plugin (-fuse-linker-plugin) with GNU ld, GNU ! binutils must be configured with --enable-largefile. ! !

To enable symbol versioning in ‘libstdc++’ with Sun ld, ! you need to have any version of GNU c++filt, which is part of ! GNU binutils. ‘libstdc++’ symbol versioning will be disabled if no ! appropriate version is found. Sun c++filt from the Sun Studio compilers does not work. ! !

Sun bug 4296832 turns up when compiling X11 headers with GCC 2.95 or ! newer: g++ will complain that types are missing. These headers assume that omitting the type means int; this assumption worked for C90 but is wrong for C++, and is now wrong for C99 also. ! !

Sun bug 4927647 sometimes causes random spurious testsuite failures ! related to missing diagnostic output. This bug doesn't affect GCC ! itself, rather it is a kernel bug triggered by the expect program which is used only by the GCC testsuite driver. When the bug ! causes the expect program to miss anticipated output, extra testsuite failures appear. ! !

There are patches for Solaris 9 (117171-11 or newer for SPARC, 117172-11 or newer for Intel) that address this problem. ! !

Thread-local storage (TLS) is supported in Solaris 9, but requires ! some patches. The ‘libthread’ patches provide the ! __tls_get_addr (SPARC, 64-bit x86) resp. ___tls_get_addr (32-bit x86) functions. On Solaris 9, the necessary support on SPARC is present since FCS, while 114432-05 or newer is required on Intel. Additionally, on Solaris 9/x86, patch 113986-02 or newer is ! required for the Sun ld and runtime linker (ld.so.1) support, while Solaris 9/SPARC works since FCS. The linker ! patches must be installed even if GNU ld is used. Sun ! as in Solaris 9 doesn't support the necessary ! relocations, so GNU as must be used. The configure script checks for those prerequisites and automatically enables TLS support if they are met. Although those minimal patch versions should work, it is recommended to use the latest patch versions which include additional bug fixes. ! !

! !

sparc*-*-*

This section contains general configuration information for all SPARC-based platforms. In addition to reading this section, please read all other sections that match your target. ! !

Newer versions of the GNU Multiple Precision Library (GMP), the MPFR library and the MPC library are known to be miscompiled by earlier versions of GCC on these platforms. We therefore recommend the use of the exact versions of these libraries listed as minimal versions in the prerequisites. ! !

! !

sparc-sun-solaris2*

When GCC is configured to use GNU binutils 2.14 or later, the binaries ! produced are smaller than the ones produced using Sun's native tools; this difference is quite significant for binaries containing debugging information. ! !

Starting with Solaris 7, the operating system is capable of executing 64-bit SPARC V9 binaries. GCC 3.1 and later properly supports ! this; the -m64 option enables 64-bit code generation. However, if all you want is code tuned for the UltraSPARC CPU, you ! should try the -mtune=ultrasparc option instead, which produces code that, unlike full 64-bit code, can still run on non-UltraSPARC machines. ! !

When configuring on a Solaris 7 or later system that is running a kernel that supports only 32-bit binaries, one must configure with ! --disable-multilib, since we will not be able to build the 64-bit target libraries. ! !

GCC 3.3 and GCC 3.4 trigger code generation bugs in earlier versions of the GNU compiler (especially GCC 3.0.x versions), which lead to the miscompilation of the stage1 compiler and the subsequent failure of the bootstrap process. A workaround is to use GCC 3.2.3 as an intermediary stage, i.e. to bootstrap that compiler with the base compiler and then use it to bootstrap the final compiler. ! !

GCC 3.4 triggers a code generation bug in versions 5.4 (Sun ONE Studio 7) and 5.5 (Sun ONE Studio 8) of the Sun compiler, which causes a bootstrap failure in form of a miscompilation of the stage1 compiler by the Sun compiler. This is Sun bug 4974440. This is fixed with patch 112760-07. ! !

GCC 3.4 changed the default debugging format from Stabs to DWARF-2 for 32-bit code on Solaris 7 and later. If you use the Sun assembler, this change apparently runs afoul of Sun bug 4910101 (which is referenced as ! an x86-only problem by Sun, probably because they do not use DWARF-2). A symptom of the problem is that you cannot compile C++ programs like ! groff 1.19.1 without getting messages similar to the following: ! ! 

     ld: warning: relocation error: R_SPARC_UA32: ...
!        external symbolic relocation against non-allocatable section
!        .debug_info cannot be processed at runtime: relocation ignored.
!
!

To work around this problem, compile with -gstabs+ instead of ! plain -g. !

When configuring the GNU Multiple Precision Library (GMP), the MPFR library or the MPC library on a Solaris 7 or later system, the canonical ! target triplet must be specified as the build parameter on the ! configure line. This target triplet can be obtained by invoking ./config.guess in the toplevel source directory of GCC (and not that of GMP or MPFR or MPC). For example on a Solaris 9 system: ! 

     % ./configure --build=sparc-sun-solaris2.9 --prefix=xxx
!
!

! !

sparc-sun-solaris2.10

There is a bug in older versions of the Sun assembler which breaks thread-local storage (TLS). A typical error message is ! 

     ld: fatal: relocation error: R_SPARC_TLS_LE_HIX22: file /var/tmp//ccamPA1v.o:
!        symbol <unknown>: bad symbol type SECT: symbol type must be TLS
!
!

This bug is fixed in Sun patch 118683-03 or later. ! !

! !

sparc-*-linux*

GCC versions 3.0 and higher require binutils 2.11.2 and glibc 2.2.4 or newer on this platform. All earlier binutils and glibc releases mishandled unaligned relocations on sparc-*-* targets. !

! !

sparc64-*-solaris2*

When configuring the GNU Multiple Precision Library (GMP), the MPFR library or the MPC library, the canonical target triplet must be specified ! as the build parameter on the configure line. For example on a Solaris 9 system: ! 

     % ./configure --build=sparc64-sun-solaris2.9 --prefix=xxx
!
!

The following compiler flags must be specified in the configure step in order to bootstrap this target with the Sun compiler: ! 

     % CC="cc -xarch=v9 -xildoff" srcdir/configure [options] [target]
!
!

-xarch=v9 specifies the SPARC-V9 architecture to the Sun toolchain ! and -xildoff turns off the incremental linker. ! !

! !

sparcv9-*-solaris2*

! !

This is a synonym for ‘sparc64-*-solaris2*’. ! !

!

c6x-*-*

The C6X family of processors. This port requires binutils-2.22 or newer. ! !

! !

tilegx-*-linux*

The TILE-Gx processor running GNU/Linux. This port requires binutils-2.22 or newer. ! !

! !

tilepro-*-linux*

The TILEPro processor running GNU/Linux. This port requires binutils-2.22 or newer. ! !

! !

*-*-vxworks*

!

Support for VxWorks is in flux. At present GCC supports only the ! very recent VxWorks 5.5 (aka Tornado 2.2) release, and only on PowerPC. ! We welcome patches for other architectures supported by VxWorks 5.5. Support for VxWorks AE would also be welcome; we believe this is merely a matter of writing an appropriate “configlette” (see below). We are not interested in supporting older, a.out or COFF-based, versions of VxWorks in GCC 3. ! !

VxWorks comes with an older version of GCC installed in ! $WIND_BASE/host; we recommend you do not overwrite it. ! Choose an installation prefix entirely outside $WIND_BASE. ! Before running configure, create the directories prefix ! and prefix/bin. Link or copy the appropriate assembler, ! linker, etc. into prefix/bin, and set your PATH to ! include that directory while running both configure and ! make. ! !

You must give configure the ! --with-headers=$WIND_BASE/target/h switch so that it can find the VxWorks system headers. Since VxWorks is a cross compilation ! target only, you must also specify --target=target. ! configure will attempt to create the directory ! prefix/target/sys-include and copy files into it; ! make sure the user running configure has sufficient privilege to do so. ! !

GCC's exception handling runtime requires a special “configlette” ! module, contrib/gthr_supp_vxw_5x.c. Follow the instructions in that file to add the module to your kernel build. (Future versions of VxWorks will incorporate this module.) ! !

! !

x86_64-*-*, amd64-*-*

GCC supports the x86-64 architecture implemented by the AMD64 processor ! (amd64-*-* is an alias for x86_64-*-*) on GNU/Linux, FreeBSD and NetBSD. On GNU/Linux the default is a bi-arch compiler which is able to generate ! both 64-bit x86-64 and 32-bit x86 code (via the -m32 switch). ! !

! !

x86_64-*-solaris2.1[0-9]*

GCC also supports the x86-64 architecture implemented by the AMD64 ! processor (‘amd64-*-*’ is an alias for ‘x86_64-*-*’) on Solaris 10 or later. Unlike other systems, without special options a bi-arch compiler is built which generates 32-bit code by default, but ! can generate 64-bit x86-64 code with the -m64 switch. Since GCC 4.7, there is also configuration that defaults to 64-bit code, but ! can generate 32-bit code with -m32. To configure and build ! this way, you have to provide all support libraries like libgmp ! as 64-bit code, configure with --target=x86_64-pc-solaris2.1x ! and ‘CC=gcc -m64’. ! !

! !

xtensa*-*-elf

This target is intended for embedded Xtensa systems using the ! ‘newlib’ C library. It uses ELF but does not support shared objects. Designed-defined instructions specified via the Tensilica Instruction Extension (TIE) language are only supported through inline assembly. ! !

The Xtensa configuration information must be specified prior to ! building GCC. The include/xtensa-config.h header file contains the configuration information. If you created your own Xtensa configuration with the Xtensa Processor Generator, the downloaded files include a customized copy of this header file, which you can use to replace the default header file. ! !

! !

xtensa*-*-linux*

This target is for Xtensa systems running GNU/Linux. It supports ELF shared objects and the GNU C library (glibc). It also generates position-independent code (PIC) regardless of whether the ! -fpic or -fPIC options are used. In other respects, this target is the same as the ! ‘xtensa*-*-elf’ target. ! !

! !

Microsoft Windows

! !

Intel 16-bit versions

The 16-bit versions of Microsoft Windows, such as Windows 3.1, are not supported. ! !

However, the 32-bit port has limited support for Microsoft Windows 3.11 in the Win32s environment, as a target only. See below. ! !

Intel 32-bit versions

The 32-bit versions of Windows, including Windows 95, Windows NT, Windows XP, and Windows Vista, are supported by several different target platforms. These targets differ in which Windows subsystem they target and which C libraries are used. !

! !

Intel 64-bit versions

GCC contains support for x86-64 using the mingw-w64 ! runtime library, available from http://mingw-w64.sourceforge.net/. This library should be used with the target triple x86_64-pc-mingw32. ! !

Presently Windows for Itanium is not supported. ! !

Windows CE

Windows CE is supported as a target only on Hitachi SuperH (sh-wince-pe), and MIPS (mips-wince-pe). ! !

Other Windows Platforms

GCC no longer supports Windows NT on the Alpha or PowerPC. ! !

GCC no longer supports the Windows POSIX subsystem. However, it does support the Interix subsystem. See above. ! !

Old target names including *-*-winnt and *-*-windowsnt are no longer used. ! !

PW32 (i386-pc-pw32) support was never completed, and the project seems to be inactive. See http://pw32.sourceforge.net/ for more information. ! !

UWIN support has been removed due to a lack of maintenance. ! !

! !

*-*-cygwin

Ports of GCC are included with the Cygwin environment. ! !

GCC will build under Cygwin without modification; it does not build ! with Microsoft's C++ compiler and there are no plans to make it do so. ! !

The Cygwin native compiler can be configured to target any 32-bit x86 cpu architecture desired; the default is i686-pc-cygwin. It should be used with as up-to-date a version of binutils as possible; use either the latest official GNU binutils release in the Cygwin distribution, or version 2.20 or above if building your own. ! !

! !

*-*-interix

The Interix target is used by OpenNT, Interix, Services For UNIX (SFU), and Subsystem for UNIX-based Applications (SUA). Applications compiled with this target run in the Interix subsystem, which is separate from the Win32 subsystem. This target was last known to work in GCC 3.3. !

! !

*-*-mingw32

! !

GCC will build with and support only MinGW runtime 3.12 and later. Earlier versions of headers are incompatible with the new default semantics of extern inline in -std=c99 and -std=gnu99 modes. ! !

! !

Older systems

GCC contains support files for many older (1980s and early 1990s) Unix variants. For the most part, support for these systems has not been deliberately removed, but it has not been maintained for several years and may suffer from bitrot. ! !

Starting with GCC 3.1, each release has a list of “obsoleted” systems. Support for these systems is still present in that release, but ! configure will fail unless the --enable-obsolete option is given. Unless a maintainer steps forward, support for these systems will be removed from the next release of GCC. ! !

Support for old systems as hosts for GCC can cause problems if the workarounds for compiler, library and operating system bugs affect the cleanliness or maintainability of the rest of GCC. In some cases, to bring GCC up on such a system, if still possible with current GCC, may require first installing an old version of GCC which did work on that system, and using it to compile a more recent GCC, to avoid bugs in the vendor compiler. Old releases of GCC 1 and GCC 2 are available in the ! old-releases directory on the GCC mirror sites. Header bugs may generally be avoided using ! fixincludes, but bugs or deficiencies in libraries and the operating system may still cause problems. ! !

Support for older systems as targets for cross-compilation is less problematic than support for them as hosts for GCC; if an enthusiast wishes to make such a target work again (including resurrecting any of the targets that never worked with GCC 2, starting from the last --- 677,1418 ---- IZ98477 for AIX 5.3 TL11 and IZ98134 for AIX 5.3 TL12). AIX 5.3 TL11 SP8, AIX 5.3 TL12 SP5, AIX 6.1 TL04 SP11, AIX 6.1 TL05 SP7, AIX 6.1 TL06 SP6, AIX 6.1 TL07 and AIX 7.1 TL01 should include the fix. !

!

Building libstdc++.a requires a fix for an AIX Assembler bug APAR IY26685 (AIX 4.3) or APAR IY25528 (AIX 5.1). It also requires a fix for another AIX Assembler bug and a co-dependent AIX Archiver fix referenced as APAR IY53606 (AIX 5.2) or as APAR IY54774 (AIX 5.1) !

!

‘libstdc++’ in GCC 3.4 increments the major version number of the ! shared object and GCC installation places the libstdc++.a shared library in a common location which will overwrite the and GCC 3.3 version of the shared library. Applications either need to be re-linked against the new shared library or the GCC 3.1 and GCC 3.3 ! versions of the ‘libstdc++’ shared object needs to be available ! to the AIX runtime loader. The GCC 3.1 ‘libstdc++.so.4’, if ! present, and GCC 3.3 ‘libstdc++.so.5’ shared objects can be installed for runtime dynamic loading using the following steps to set ! the ‘F_LOADONLY’ flag in the shared object for each ! multilib libstdc++.a installed: !

!

Extract the shared objects from the currently installed ! libstdc++.a archive: !

! 
% ar -x libstdc++.a libstdc++.so.4 libstdc++.so.5
!
!

Enable the ‘F_LOADONLY’ flag so that the shared object will be available for runtime dynamic loading, but not linking: !

! 
% strip -e libstdc++.so.4 libstdc++.so.5
!
! !

Archive the runtime-only shared object in the GCC 3.4 ! libstdc++.a archive: !

! 
% ar -q libstdc++.a libstdc++.so.4 libstdc++.so.5
!
! !

Linking executables and shared libraries may produce warnings of duplicate symbols. The assembly files generated by GCC for AIX always have included multiple symbol definitions for certain global variable and function declarations in the original program. The warnings should not prevent the linker from producing a correct library or runnable executable. !

!

AIX 4.3 utilizes a “large format” archive to support both 32-bit and 64-bit object modules. The routines provided in AIX 4.3.0 and AIX 4.3.1 ! to parse archive libraries did not handle the new format correctly. These routines are used by GCC and result in error messages during linking such as “not a COFF file”. The version of the routines shipped ! with AIX 4.3.1 should work for a 32-bit environment. The -g option of the archive command may be used to create archives of 32-bit objects using the original “small format”. A correct version of the routines is shipped with AIX 4.3.2 and above. !

!

Some versions of the AIX binder (linker) can fail with a relocation ! overflow severe error when the -bbigtoc option is used to link GCC-produced object files into an executable that overflows the TOC. A fix for APAR IX75823 (OVERFLOW DURING LINK WHEN USING GCC AND -BBIGTOC) is available from IBM Customer Support and from its techsupport.services.ibm.com website as PTF U455193. !

!

The AIX 4.3.2.1 linker (bos.rte.bind_cmds Level 4.3.2.1) will dump core with a segmentation fault when invoked by any version of GCC. A fix for APAR IX87327 is available from IBM Customer Support and from its techsupport.services.ibm.com website as PTF U461879. This fix is incorporated in AIX 4.3.3 and above. !

!

The initial assembler shipped with AIX 4.3.0 generates incorrect object files. A fix for APAR IX74254 (64BIT DISASSEMBLED OUTPUT FROM COMPILER FAILS TO ASSEMBLE/BIND) is available from IBM Customer Support and from its techsupport.services.ibm.com website as PTF U453956. This fix is incorporated in AIX 4.3.1 and above. !

!

AIX provides National Language Support (NLS). Compilers and assemblers use NLS to support locale-specific representations of various data ! formats including floating-point numbers (e.g., ‘.’ vs ‘,’ for separating decimal fractions). There have been problems reported where GCC does not produce the same floating-point formats that the assembler ! expects. If one encounters this problem, set the LANG ! environment variable to ‘C’ or ‘En_US’. !

!

A default can be specified with the -mcpu=cpu_type ! switch and using the configure option --with-cpu-cpu_type. !

!

m68k-*-*

By default, ! ‘m68k-*-elf*’, ‘m68k-*-rtems’, ‘m68k-*-uclinux’ and ! ‘m68k-*-linux’ build libraries for both M680x0 and ColdFire processors. If you only need the M680x0 libraries, you can omit the ColdFire ones by passing ! --with-arch=m68k to configure. Alternatively, you ! can omit the M680x0 libraries by passing --with-arch=cf to ! configure. These targets default to 5206 or 5475 code as appropriate for the target system when ! configured with --with-arch=cf and 68020 code otherwise. !

!

The ‘m68k-*-netbsd’ and ! ‘m68k-*-openbsd’ targets also support the --with-arch option. They will generate ColdFire CFV4e code when configured with ! --with-arch=cf and 68020 code otherwise. !

!

You can override the default processors listed above by configuring ! with --with-cpu=target. This target can either ! be a -mcpu argument or one of the following values: ! ‘m68000’, ‘m68010’, ‘m68020’, ‘m68030’, ! ‘m68040’, ‘m68060’, ‘m68020-40’ and ‘m68020-60’. !

!

GCC requires at least binutils version 2.17 on these targets. !

!
!

m68k-*-uclinux

GCC 4.3 changed the uClinux configuration so that it uses the ! ‘m68k-linux-gnu’ ABI rather than the ‘m68k-elf’ ABI. It also added improved support for C++ and flat shared libraries, both of which were ABI changes. +

!
!

mep-*-elf

!

Toshiba Media embedded Processor. This configuration is intended for embedded systems. !

!
!

microblaze-*-elf

!

Xilinx MicroBlaze processor. This configuration is intended for embedded systems. !

!
!

mips-*-*

If on a MIPS system you get an error message saying “does not have gp ! sections for all it’s [sic] sectons [sic]”, don’t worry about it. This happens whenever you use GAS with the MIPS linker, but there is not really anything wrong, and it is okay to use the output file. You can stop such warnings by installing the GNU linker. !

!

It would be nice to extend GAS to produce the gp tables, but they are optional, and there should not be a warning about their absence. !

!

The libstdc++ atomic locking routines for MIPS targets requires MIPS II and later. A patch went in just after the GCC 3.3 release to ! make ‘mips*-*-*’ use the generic implementation instead. You can also ! configure for ‘mipsel-elf’ as a workaround. The ! ‘mips*-*-linux*’ target continues to use the MIPS II routines. More work on this is expected in future releases. +

!

The built-in __sync_* functions are available on MIPS II and ! later systems and others that support the ‘ll’, ‘sc’ and ! ‘sync’ instructions. This can be overridden by passing ! --with-llsc or --without-llsc when configuring GCC. Since the Linux kernel emulates these instructions if they are ! missing, the default for ‘mips*-*-linux*’ targets is ! --with-llsc. The --with-llsc and ! --without-llsc configure options may be overridden at compile ! time by passing the -mllsc or -mno-llsc options to the compiler. !

!

MIPS systems check for division by zero (unless ! -mno-check-zero-division is passed to the compiler) by generating either a conditional trap or a break instruction. Using trap results in smaller code, but is only supported on MIPS II and later. Also, some versions of the Linux kernel have a bug that prevents trap from generating the proper signal (SIGFPE). To enable ! the use of break, use the --with-divide=breaks ! configure option when configuring GCC. The default is to use traps on systems that support them. !

!

The assembler from GNU binutils 2.17 and earlier has a bug in the way it sorts relocations for REL targets (o32, o64, EABI). This can cause bad code to be generated for simple C++ programs. Also the linker from GNU binutils versions prior to 2.17 has a bug which causes the ! runtime linker stubs in very large programs, like libgcj.so, to be incorrectly generated. GNU Binutils 2.18 and later (and snapshots made after Nov. 9, 2006) should be free from both of these problems. !

!

s390x-ibm-tpf*

zSeries system (64-bit) running TPF. This platform is supported as cross-compilation target only. !

!
!

*-*-solaris2*

Support for Solaris 8 has removed in GCC 4.8. Support for Solaris 7 has been removed in GCC 4.6. !

!

Sun does not ship a C compiler with Solaris 2 before Solaris 10, though you can download the Sun Studio compilers for free. In Solaris 10 and ! 11, GCC 3.4.3 is available as /usr/sfw/bin/gcc. Solaris 11 ! also provides GCC 4.5.2 as /usr/gcc/4.5/bin/gcc. Alternatively, you can install a pre-built GCC to bootstrap and install GCC. See the binaries page for details. !

!

The Solaris 2 /bin/sh will often fail to configure ! ‘libstdc++-v3’, ‘boehm-gc’ or ‘libjava’. We therefore recommend using the following initial sequence of commands +

+
+ 
% CONFIG_SHELL=/bin/ksh
+ % export CONFIG_SHELL
+
!

and proceed as described in the configure instructions. In addition we strongly recommend specifying an absolute path to invoke ! srcdir/configure. !

!

Solaris 2 comes with a number of optional OS packages. Some of these are needed to use GCC fully, namely SUNWarc, SUNWbtool, SUNWesu, SUNWhea, SUNWlibm, SUNWsprot, and SUNWtoo. If you did not install all optional packages when installing Solaris 2, you will need to verify that the packages that GCC needs are installed. !

!

To check whether an optional package is installed, use ! the pkginfo command. To add an optional package, use the ! pkgadd command. For further details, see the Solaris 2 documentation. !

!

Trying to use the linker and other tools in ! /usr/ucb to install GCC has been observed to cause trouble. For example, the linker may hang indefinitely. The fix is to remove ! /usr/ucb from your PATH. !

!

The build process works more smoothly with the legacy Sun tools so, if you ! have /usr/xpg4/bin in your PATH, we recommend that you place ! /usr/bin before /usr/xpg4/bin for the duration of the build. !

!

We recommend the use of the Sun assembler or the GNU assembler, in ! conjunction with the Sun linker. The GNU as versions included in Solaris 10, from GNU binutils 2.15, and Solaris 11, from GNU binutils 2.19, are known to work. They can be found in ! /usr/sfw/bin/gas. Current versions of GNU binutils (2.22) are known to work as well. Note that your mileage may vary if you use a combination of the GNU tools and the Sun tools: while the ! combination GNU as + Sun ld should reasonably work, ! the reverse combination Sun as + GNU ld may fail to ! build or cause memory corruption at runtime in some cases for C++ programs. ! GNU ld usually works as well, although the version included in Solaris 10 cannot be used due to several bugs. Again, the current version (2.22) is known to work, but generally lacks platform specific ! features, so better stay with Sun ld. To use the LTO linker ! plugin (-fuse-linker-plugin) with GNU ld, GNU ! binutils must be configured with --enable-largefile. !

!

To enable symbol versioning in ‘libstdc++’ with Sun ld, ! you need to have any version of GNU c++filt, which is part of ! GNU binutils. ‘libstdc++’ symbol versioning will be disabled if no ! appropriate version is found. Sun c++filt from the Sun Studio compilers does not work. !

!

Sun bug 4296832 turns up when compiling X11 headers with GCC 2.95 or ! newer: g++ will complain that types are missing. These headers assume that omitting the type means int; this assumption worked for C90 but is wrong for C++, and is now wrong for C99 also. !

!

Sun bug 4927647 sometimes causes random spurious testsuite failures ! related to missing diagnostic output. This bug doesn’t affect GCC ! itself, rather it is a kernel bug triggered by the expect program which is used only by the GCC testsuite driver. When the bug ! causes the expect program to miss anticipated output, extra testsuite failures appear. !

!

There are patches for Solaris 9 (117171-11 or newer for SPARC, 117172-11 or newer for Intel) that address this problem. !

!

Thread-local storage (TLS) is supported in Solaris 9, but requires ! some patches. The ‘libthread’ patches provide the ! __tls_get_addr (SPARC, 64-bit x86) resp. ___tls_get_addr (32-bit x86) functions. On Solaris 9, the necessary support on SPARC is present since FCS, while 114432-05 or newer is required on Intel. Additionally, on Solaris 9/x86, patch 113986-02 or newer is ! required for the Sun ld and runtime linker (ld.so.1) support, while Solaris 9/SPARC works since FCS. The linker ! patches must be installed even if GNU ld is used. Sun ! as in Solaris 9 doesn’t support the necessary ! relocations, so GNU as must be used. The configure script checks for those prerequisites and automatically enables TLS support if they are met. Although those minimal patch versions should work, it is recommended to use the latest patch versions which include additional bug fixes. !

!
!

sparc*-*-*

This section contains general configuration information for all SPARC-based platforms. In addition to reading this section, please read all other sections that match your target. !

!

Newer versions of the GNU Multiple Precision Library (GMP), the MPFR library and the MPC library are known to be miscompiled by earlier versions of GCC on these platforms. We therefore recommend the use of the exact versions of these libraries listed as minimal versions in the prerequisites. !

!
!

sparc-sun-solaris2*

When GCC is configured to use GNU binutils 2.14 or later, the binaries ! produced are smaller than the ones produced using Sun’s native tools; this difference is quite significant for binaries containing debugging information. !

!

Starting with Solaris 7, the operating system is capable of executing 64-bit SPARC V9 binaries. GCC 3.1 and later properly supports ! this; the -m64 option enables 64-bit code generation. However, if all you want is code tuned for the UltraSPARC CPU, you ! should try the -mtune=ultrasparc option instead, which produces code that, unlike full 64-bit code, can still run on non-UltraSPARC machines. !

!

When configuring on a Solaris 7 or later system that is running a kernel that supports only 32-bit binaries, one must configure with ! --disable-multilib, since we will not be able to build the 64-bit target libraries. !

!

GCC 3.3 and GCC 3.4 trigger code generation bugs in earlier versions of the GNU compiler (especially GCC 3.0.x versions), which lead to the miscompilation of the stage1 compiler and the subsequent failure of the bootstrap process. A workaround is to use GCC 3.2.3 as an intermediary stage, i.e. to bootstrap that compiler with the base compiler and then use it to bootstrap the final compiler. !

!

GCC 3.4 triggers a code generation bug in versions 5.4 (Sun ONE Studio 7) and 5.5 (Sun ONE Studio 8) of the Sun compiler, which causes a bootstrap failure in form of a miscompilation of the stage1 compiler by the Sun compiler. This is Sun bug 4974440. This is fixed with patch 112760-07. !

!

GCC 3.4 changed the default debugging format from Stabs to DWARF-2 for 32-bit code on Solaris 7 and later. If you use the Sun assembler, this change apparently runs afoul of Sun bug 4910101 (which is referenced as ! an x86-only problem by Sun, probably because they do not use DWARF-2). A symptom of the problem is that you cannot compile C++ programs like ! groff 1.19.1 without getting messages similar to the following: !

!
! 
ld: warning: relocation error: R_SPARC_UA32: …
!   external symbolic relocation against non-allocatable section
!   .debug_info cannot be processed at runtime: relocation ignored.
!
!

To work around this problem, compile with -gstabs+ instead of ! plain -g. !

!

When configuring the GNU Multiple Precision Library (GMP), the MPFR library or the MPC library on a Solaris 7 or later system, the canonical ! target triplet must be specified as the build parameter on the ! configure line. This target triplet can be obtained by invoking ./config.guess in the toplevel source directory of GCC (and not that of GMP or MPFR or MPC). For example on a Solaris 9 system: +

+
+ 
% ./configure --build=sparc-sun-solaris2.9 --prefix=xxx
+
!
!

sparc-sun-solaris2.10

There is a bug in older versions of the Sun assembler which breaks thread-local storage (TLS). A typical error message is +

+
+ 
ld: fatal: relocation error: R_SPARC_TLS_LE_HIX22: file /var/tmp//ccamPA1v.o:
+   symbol <unknown>: bad symbol type SECT: symbol type must be TLS
+
!

This bug is fixed in Sun patch 118683-03 or later. !

!
!

sparc-*-linux*

GCC versions 3.0 and higher require binutils 2.11.2 and glibc 2.2.4 or newer on this platform. All earlier binutils and glibc releases mishandled unaligned relocations on sparc-*-* targets. +

!
!

sparc64-*-solaris2*

When configuring the GNU Multiple Precision Library (GMP), the MPFR library or the MPC library, the canonical target triplet must be specified ! as the build parameter on the configure line. For example on a Solaris 9 system: +

+
+ 
% ./configure --build=sparc64-sun-solaris2.9 --prefix=xxx
+
!

The following compiler flags must be specified in the configure step in order to bootstrap this target with the Sun compiler: +

+
+ 
% CC="cc -xarch=v9 -xildoff" srcdir/configure [options] [target]
+
!

-xarch=v9 specifies the SPARC-V9 architecture to the Sun toolchain ! and -xildoff turns off the incremental linker. !

!
!

sparcv9-*-solaris2*

!

This is a synonym for ‘sparc64-*-solaris2*’. !

!
!

c6x-*-*

The C6X family of processors. This port requires binutils-2.22 or newer. !

!
!

tilegx-*-linux*

The TILE-Gx processor running GNU/Linux. This port requires binutils-2.22 or newer. !

!
!

tilepro-*-linux*

The TILEPro processor running GNU/Linux. This port requires binutils-2.22 or newer. !

!
!

*-*-vxworks*

Support for VxWorks is in flux. At present GCC supports only the ! very recent VxWorks 5.5 (aka Tornado 2.2) release, and only on PowerPC. ! We welcome patches for other architectures supported by VxWorks 5.5. Support for VxWorks AE would also be welcome; we believe this is merely a matter of writing an appropriate “configlette” (see below). We are not interested in supporting older, a.out or COFF-based, versions of VxWorks in GCC 3. !

!

VxWorks comes with an older version of GCC installed in ! $WIND_BASE/host; we recommend you do not overwrite it. ! Choose an installation prefix entirely outside $WIND_BASE. ! Before running configure, create the directories prefix ! and prefix/bin. Link or copy the appropriate assembler, ! linker, etc. into prefix/bin, and set your PATH to ! include that directory while running both configure and ! make. !

!

You must give configure the ! --with-headers=$WIND_BASE/target/h switch so that it can find the VxWorks system headers. Since VxWorks is a cross compilation ! target only, you must also specify --target=target. ! configure will attempt to create the directory ! prefix/target/sys-include and copy files into it; ! make sure the user running configure has sufficient privilege to do so. !

!

GCC’s exception handling runtime requires a special “configlette” ! module, contrib/gthr_supp_vxw_5x.c. Follow the instructions in that file to add the module to your kernel build. (Future versions of VxWorks will incorporate this module.) !

!
!

x86_64-*-*, amd64-*-*

GCC supports the x86-64 architecture implemented by the AMD64 processor ! (amd64-*-* is an alias for x86_64-*-*) on GNU/Linux, FreeBSD and NetBSD. On GNU/Linux the default is a bi-arch compiler which is able to generate ! both 64-bit x86-64 and 32-bit x86 code (via the -m32 switch). !

!
!

x86_64-*-solaris2.1[0-9]*

GCC also supports the x86-64 architecture implemented by the AMD64 ! processor (‘amd64-*-*’ is an alias for ‘x86_64-*-*’) on Solaris 10 or later. Unlike other systems, without special options a bi-arch compiler is built which generates 32-bit code by default, but ! can generate 64-bit x86-64 code with the -m64 switch. Since GCC 4.7, there is also configuration that defaults to 64-bit code, but ! can generate 32-bit code with -m32. To configure and build ! this way, you have to provide all support libraries like libgmp ! as 64-bit code, configure with --target=x86_64-pc-solaris2.1x ! and ‘CC=gcc -m64’. !

!
!

xtensa*-*-elf

This target is intended for embedded Xtensa systems using the ! ‘newlib’ C library. It uses ELF but does not support shared objects. Designed-defined instructions specified via the Tensilica Instruction Extension (TIE) language are only supported through inline assembly. !

!

The Xtensa configuration information must be specified prior to ! building GCC. The include/xtensa-config.h header file contains the configuration information. If you created your own Xtensa configuration with the Xtensa Processor Generator, the downloaded files include a customized copy of this header file, which you can use to replace the default header file. !

!
!

xtensa*-*-linux*

This target is for Xtensa systems running GNU/Linux. It supports ELF shared objects and the GNU C library (glibc). It also generates position-independent code (PIC) regardless of whether the ! -fpic or -fPIC options are used. In other respects, this target is the same as the ! ‘xtensa*-*-elf’ target. !

!
!

Microsoft Windows

+ +

Intel 16-bit versions

The 16-bit versions of Microsoft Windows, such as Windows 3.1, are not supported. !

!

However, the 32-bit port has limited support for Microsoft Windows 3.11 in the Win32s environment, as a target only. See below. !

! !

Intel 32-bit versions

The 32-bit versions of Windows, including Windows 95, Windows NT, Windows XP, and Windows Vista, are supported by several different target platforms. These targets differ in which Windows subsystem they target and which C libraries are used. +

+ ! !

Intel 64-bit versions

GCC contains support for x86-64 using the mingw-w64 ! runtime library, available from http://mingw-w64.sourceforge.net/. This library should be used with the target triple x86_64-pc-mingw32. !

!

Presently Windows for Itanium is not supported. !

! !

Windows CE

Windows CE is supported as a target only on Hitachi SuperH (sh-wince-pe), and MIPS (mips-wince-pe). !

! !

Other Windows Platforms

GCC no longer supports Windows NT on the Alpha or PowerPC. !

!

GCC no longer supports the Windows POSIX subsystem. However, it does support the Interix subsystem. See above. !

!

Old target names including *-*-winnt and *-*-windowsnt are no longer used. !

!

PW32 (i386-pc-pw32) support was never completed, and the project seems to be inactive. See http://pw32.sourceforge.net/ for more information. !

!

UWIN support has been removed due to a lack of maintenance. !

!
!

*-*-cygwin

Ports of GCC are included with the Cygwin environment. !

!

GCC will build under Cygwin without modification; it does not build ! with Microsoft’s C++ compiler and there are no plans to make it do so. !

!

The Cygwin native compiler can be configured to target any 32-bit x86 cpu architecture desired; the default is i686-pc-cygwin. It should be used with as up-to-date a version of binutils as possible; use either the latest official GNU binutils release in the Cygwin distribution, or version 2.20 or above if building your own. !

!
!

*-*-interix

The Interix target is used by OpenNT, Interix, Services For UNIX (SFU), and Subsystem for UNIX-based Applications (SUA). Applications compiled with this target run in the Interix subsystem, which is separate from the Win32 subsystem. This target was last known to work in GCC 3.3. +

+
+

*-*-mingw32

!

GCC will build with and support only MinGW runtime 3.12 and later. Earlier versions of headers are incompatible with the new default semantics of extern inline in -std=c99 and -std=gnu99 modes. !

!
!

Older systems

GCC contains support files for many older (1980s and early 1990s) Unix variants. For the most part, support for these systems has not been deliberately removed, but it has not been maintained for several years and may suffer from bitrot. !

!

Starting with GCC 3.1, each release has a list of “obsoleted” systems. Support for these systems is still present in that release, but ! configure will fail unless the --enable-obsolete option is given. Unless a maintainer steps forward, support for these systems will be removed from the next release of GCC. !

!

Support for old systems as hosts for GCC can cause problems if the workarounds for compiler, library and operating system bugs affect the cleanliness or maintainability of the rest of GCC. In some cases, to bring GCC up on such a system, if still possible with current GCC, may require first installing an old version of GCC which did work on that system, and using it to compile a more recent GCC, to avoid bugs in the vendor compiler. Old releases of GCC 1 and GCC 2 are available in the ! old-releases directory on the GCC mirror ! sites. Header bugs may generally be avoided using ! fixincludes, but bugs or deficiencies in libraries and the operating system may still cause problems. !

!

Support for older systems as targets for cross-compilation is less problematic than support for them as hosts for GCC; if an enthusiast wishes to make such a target work again (including resurrecting any of the targets that never worked with GCC 2, starting from the last *************** version before they were removed), patch *** 1443,1473 **** following the usual requirements would be likely to be accepted, since they should not affect the support for more modern targets. ! !

For some systems, old versions of GNU binutils may also be useful, ! and are available from pub/binutils/old-releases on sourceware.org mirror sites. ! !

Some of the information on specific systems above relates to such older systems, but much of the information about GCC on such systems (which may no longer be applicable to current GCC) is to be found in the GCC texinfo manual. ! !

! !

all ELF targets (SVR4, Solaris 2, etc.)

C++ support is significantly better on ELF targets if you use the GNU linker; duplicate copies of inlines, vtables and template instantiations will be discarded automatically. -

Installing GCC: Testing

! ! Before you install GCC, we encourage you to run the testsuites and to compare your results with results from a similar configuration that have been submitted to the ! gcc-testresults mailing list. Some of these archived results are linked from the build status lists at http://gcc.gnu.org/buildstat.html, although not everyone who ! reports a successful build runs the testsuites and submits the results. This step is optional and may require you to download additional software, but it can give you confidence in your new GCC installation or point out problems before you install and start using your new GCC. ! !

First, you must have downloaded the testsuites. These are part of the full distribution, but if you downloaded the “core” compiler plus any front ends, you must download the testsuites separately. ! !

Second, you must have the testing tools installed. This includes DejaGnu, Tcl, and Expect; the DejaGnu site has links to these. ! !

If the directories where runtest and expect were ! installed are not in the PATH, you may need to set the following environment variables appropriately, as in the following example (which ! assumes that DejaGnu has been installed under /usr/local): ! 

     TCL_LIBRARY = /usr/local/share/tcl8.0
!      DEJAGNULIBS = /usr/local/share/dejagnu
!
!

(On systems such as Cygwin, these paths are required to be actual paths, not mounts or links; presumably this is due to some lack of portability in the DejaGnu code.) !

Finally, you can run the testsuite (which may take a long time): ! 

     cd objdir; make -k check
!
!

This will test various components of GCC, such as compiler front ends and runtime libraries. While running the testsuite, DejaGnu might emit some harmless messages resembling ! ‘WARNING: Couldn't find the global config file.’ or ! ‘WARNING: Couldn't find tool init file’ that can be ignored. ! !

If you are testing a cross-compiler, you may want to run the testsuite on a simulator as described at http://gcc.gnu.org/simtest-howto.html. ! !

How can you run the testsuite on selected tests?

In order to run sets of tests selectively, there are targets ! ‘make check-gcc’ and language specific ‘make check-c’, ! ‘make check-c++’, ‘make check-fortran’, ‘make check-java’, ! ‘make check-ada’, ‘make check-objc’, ‘make check-obj-c++’, ! ‘make check-lto’ ! in the gcc subdirectory of the object directory. You can also ! just run ‘make check’ in a subdirectory of the object directory. !

A more selective way to just run all gcc execute tests in the testsuite is to use ! 

     make check-gcc RUNTESTFLAGS="execute.exp other-options"
!
!

Likewise, in order to run only the g++ “old-deja” tests in ! the testsuite with filenames matching ‘9805*’, you would use ! ! 

     make check-g++ RUNTESTFLAGS="old-deja.exp=9805* other-options"
!
!

The *.exp files are located in the testsuite directories of the GCC ! source, the most important ones being compile.exp, ! execute.exp, dg.exp and old-deja.exp. ! To get a list of the possible *.exp files, pipe the ! output of ‘make check’ into a file and look at the ! ‘Running ... .exp’ lines. !

Passing options and running multiple testsuites

You can pass multiple options to the testsuite using the ! ‘--target_board’ option of DejaGNU, either passed as part of ! ‘RUNTESTFLAGS’, or directly to runtest if you prefer to work outside the makefiles. For example, ! 

     make check-g++ RUNTESTFLAGS="--target_board=unix/-O3/-fmerge-constants"
!
!

will run the standard g++ testsuites (“unix” is the target name for a standard native testsuite situation), passing ! ‘-O3 -fmerge-constants’ to the compiler on every test, i.e., slashes separate options. ! !

You can run the testsuites multiple times using combinations of options with a syntax similar to the brace expansion of popular shells: ! 

     ..."--target_board=arm-sim\{-mhard-float,-msoft-float\}\{-O1,-O2,-O3,\}"
!
!

(Note the empty option caused by the trailing comma in the final group.) ! The following will run each testsuite eight times using the ‘arm-sim’ target, as if you had specified all possible combinations yourself: ! 

     --target_board='arm-sim/-mhard-float/-O1 \
!                      arm-sim/-mhard-float/-O2 \
!                      arm-sim/-mhard-float/-O3 \
!                      arm-sim/-mhard-float \
!                      arm-sim/-msoft-float/-O1 \
!                      arm-sim/-msoft-float/-O2 \
!                      arm-sim/-msoft-float/-O3 \
!                      arm-sim/-msoft-float'
!
!

They can be combined as many times as you wish, in arbitrary ways. This list: ! 

     ..."--target_board=unix/-Wextra\{-O3,-fno-strength\}\{-fomit-frame,\}"
!
!

will generate four combinations, all involving ‘-Wextra’. ! !

The disadvantage to this method is that the testsuites are run in serial, which is a waste on multiprocessor systems. For users with GNU Make and a shell which performs brace expansion, you can run the testsuites in ! parallel by having the shell perform the combinations and make ! do the parallel runs. Instead of using ‘--target_board’, use a special makefile target: ! 

     make -jN check-testsuite//test-target/option1/option2/...
!
!

For example, ! 

     make -j3 check-gcc//sh-hms-sim/{-m1,-m2,-m3,-m3e,-m4}/{,-nofpu}
!
!

will run three concurrent “make-gcc” testsuites, eventually testing all ten combinations as described above. Note that this is currently only ! supported in the gcc subdirectory. (To see how this works, try ! typing echo before the example given here.) !

Additional testing for Java Class Libraries

!

The Java runtime tests can be executed via ‘make check’ ! in the target/libjava/testsuite directory in the build tree. ! !

The Mauve Project provides a suite of tests for the Java Class Libraries. This suite can be run as part of libgcj testing by placing the Mauve tree within the libjava ! testsuite at libjava/testsuite/libjava.mauve/mauve, or by ! specifying the location of that tree when invoking ‘make’, as in ! ‘make MAUVEDIR=~/mauve check’. ! !

How to interpret test results

!

The result of running the testsuite are various *.sum and *.log ! files in the testsuite subdirectories. The *.log files contain a detailed log of the compiler invocations and the corresponding ! results, the *.sum files summarize the results. These summaries contain status codes for all tests: !

! !

It is normal for some tests to report unexpected failures. At the current time the testing harness does not allow fine grained control over whether or not a test is expected to fail. This problem should be fixed in future releases. !

Submitting test results

If you want to report the results to the GCC project, use the ! contrib/test_summary shell script. Start it in the objdir with ! 

     srcdir/contrib/test_summary -p your_commentary.txt \
!          -m gcc-testresults@gcc.gnu.org |sh
!
!

This script uses the Mail program to send the results, so ! make sure it is in your PATH. The file your_commentary.txt is prepended to the testsuite summary and should contain any special remarks you have on your results or your build environment. Please do not edit the testsuite result block or the subject line, as these messages may be automatically processed. -

If you are testing a cross-compiler, you may want to run the testsuite on a simulator as described at http://gcc.gnu.org/simtest-howto.html. !

! !

How can you run the testsuite on selected tests?

In order to run sets of tests selectively, there are targets ! ‘make check-gcc’ and language specific ‘make check-c’, ! ‘make check-c++’, ‘make check-fortran’, ‘make check-java’, ! ‘make check-ada’, ‘make check-objc’, ‘make check-obj-c++’, ! ‘make check-lto’ ! in the gcc subdirectory of the object directory. You can also ! just run ‘make check’ in a subdirectory of the object directory. !

!

A more selective way to just run all gcc execute tests in the testsuite is to use +

+
+ 
make check-gcc RUNTESTFLAGS="execute.exp other-options"
+
!

Likewise, in order to run only the g++ “old-deja” tests in ! the testsuite with filenames matching ‘9805*’, you would use !

!
! 
make check-g++ RUNTESTFLAGS="old-deja.exp=9805* other-options"
!
!

The *.exp files are located in the testsuite directories of the GCC ! source, the most important ones being compile.exp, ! execute.exp, dg.exp and old-deja.exp. ! To get a list of the possible *.exp files, pipe the ! output of ‘make check’ into a file and look at the ! ‘Running … .exp’ lines. !

! !

Passing options and running multiple testsuites

You can pass multiple options to the testsuite using the ! ‘--target_board’ option of DejaGNU, either passed as part of ! ‘RUNTESTFLAGS’, or directly to runtest if you prefer to work outside the makefiles. For example, +

+
+ 
make check-g++ RUNTESTFLAGS="--target_board=unix/-O3/-fmerge-constants"
+
!

will run the standard g++ testsuites (“unix” is the target name for a standard native testsuite situation), passing ! ‘-O3 -fmerge-constants’ to the compiler on every test, i.e., slashes separate options. !

!

You can run the testsuites multiple times using combinations of options with a syntax similar to the brace expansion of popular shells: +

+
+ 
…"--target_board=arm-sim\{-mhard-float,-msoft-float\}\{-O1,-O2,-O3,\}"
+
!

(Note the empty option caused by the trailing comma in the final group.) ! The following will run each testsuite eight times using the ‘arm-sim’ target, as if you had specified all possible combinations yourself: +

+
+ 
--target_board='arm-sim/-mhard-float/-O1 \
+                 arm-sim/-mhard-float/-O2 \
+                 arm-sim/-mhard-float/-O3 \
+                 arm-sim/-mhard-float \
+                 arm-sim/-msoft-float/-O1 \
+                 arm-sim/-msoft-float/-O2 \
+                 arm-sim/-msoft-float/-O3 \
+                 arm-sim/-msoft-float'
+
!

They can be combined as many times as you wish, in arbitrary ways. This list: +

+
+ 
…"--target_board=unix/-Wextra\{-O3,-fno-strength\}\{-fomit-frame,\}"
+
!

will generate four combinations, all involving ‘-Wextra’. !

!

The disadvantage to this method is that the testsuites are run in serial, which is a waste on multiprocessor systems. For users with GNU Make and a shell which performs brace expansion, you can run the testsuites in ! parallel by having the shell perform the combinations and make ! do the parallel runs. Instead of using ‘--target_board’, use a special makefile target: +

+
+ 
make -jN check-testsuite//test-target/option1/option2/…
+
!

For example, !

!
! 
make -j3 check-gcc//sh-hms-sim/{-m1,-m2,-m3,-m3e,-m4}/{,-nofpu}
!
!

will run three concurrent “make-gcc” testsuites, eventually testing all ten combinations as described above. Note that this is currently only ! supported in the gcc subdirectory. (To see how this works, try ! typing echo before the example given here.) !

! !

Additional testing for Java Class Libraries

!

The Java runtime tests can be executed via ‘make check’ ! in the target/libjava/testsuite directory in the build tree. !

!

The Mauve Project provides a suite of tests for the Java Class Libraries. This suite can be run as part of libgcj testing by placing the Mauve tree within the libjava ! testsuite at libjava/testsuite/libjava.mauve/mauve, or by ! specifying the location of that tree when invoking ‘make’, as in ! ‘make MAUVEDIR=~/mauve check’. !

! !

How to interpret test results

!

The result of running the testsuite are various *.sum and *.log ! files in the testsuite subdirectories. The *.log files contain a detailed log of the compiler invocations and the corresponding ! results, the *.sum files summarize the results. These summaries contain status codes for all tests: +

+ !

It is normal for some tests to report unexpected failures. At the current time the testing harness does not allow fine grained control over whether or not a test is expected to fail. This problem should be fixed in future releases. +

! !

Submitting test results

If you want to report the results to the GCC project, use the ! contrib/test_summary shell script. Start it in the objdir with !

!
! 
srcdir/contrib/test_summary -p your_commentary.txt \
!     -m gcc-testresults@gcc.gnu.org |sh
!
!

This script uses the Mail program to send the results, so ! make sure it is in your PATH. The file your_commentary.txt is prepended to the testsuite summary and should contain any special remarks you have on your results or your build environment. Please do not edit the testsuite result block or the subject line, as these messages may be automatically processed. +

The special operator 'defined' is used in '#if' and '#elif' expressions ! to test whether a certain name is defined as a macro. 'defined NAME' ! and 'defined (NAME)' are both expressions whose value is 1 if NAME is ! defined as a macro at the current point in the program, and 0 otherwise. ! Thus, '#if defined MACRO' is precisely equivalent to '#ifdef MACRO'. ! 'defined' is useful when you wish to test more than one macro for existence at once. For example, #if defined (__vax__) || defined (__ns16000__) ! would succeed if either of the names '__vax__' or '__ns16000__' is defined as a macro. Conditionals written like this: #if defined BUFSIZE && BUFSIZE >= 1024 ! can generally be simplified to just '#if BUFSIZE >= 1024', since if !

Quoted text is introduced by the usual single and double ! quotes, and also by an initial '<' in a '#include' directive. Traditionally, comments are completely removed and are not replaced ! with a space. Since a traditional compiler does its own tokenization of ! the output of the preprocessor, this means that comments can effectively ! be used as token paste operators. However, comments behave like ! separators for text handled by the preprocessor itself, since it doesn't ! re-lex its input. For example, in #if foo/**/bar ! 'foo' and 'bar' are distinct identifiers and expanded separately if they ! happen to be macros.

This program's purpose is to translate your command into invocations of the programs that do the actual work. Their command line interfaces are similar but not identical to the documented interface, and may change without notice. The C preprocessor expects two file names as arguments, INFILE and ! OUTFILE. The preprocessor reads INFILE together with any other files it ! specifies with '#include'. All the output generated by the combined input files is written in OUTFILE. ! Either INFILE or OUTFILE may be '-', which as INFILE means to read from standard input and as OUTFILE means to write to standard output. ! Also, if either file is omitted, it means the same as if '-' had been specified for that file. !

This is typical output: *************** single-letter options may _not_ be group *** 4248,4689 **** test.h: ! `-MT TARGET' Change the target of the rule emitted by dependency generation. By default CPP takes the name of the main input file, deletes any ! directory components and any file suffix such as `.c', and appends the platform's usual object suffix. The result is the target. ! An `-MT' option will set the target to be exactly the string you specify. If you want multiple targets, you can specify them as a ! single argument to `-MT', or use multiple `-MT' options. ! For example, `-MT '$(objpfx)foo.o'' might give $(objpfx)foo.o: foo.c ! `-MQ TARGET' ! Same as `-MT', but it quotes any characters which are special to ! Make. `-MQ '$(objpfx)foo.o'' gives $$(objpfx)foo.o: foo.c The default target is automatically quoted, as if it were given ! with `-MQ'. ! `-MD' ! `-MD' is equivalent to `-M -MF FILE', except that `-E' is not ! implied. The driver determines FILE based on whether an `-o' ! option is given. If it is, the driver uses its argument but with ! a suffix of `.d', otherwise it takes the name of the input file, ! removes any directory components and suffix, and applies a `.d' suffix. ! If `-MD' is used in conjunction with `-E', any `-o' switch is understood to specify the dependency output file (*note -MF: ! dashMF.), but if used without `-E', each `-o' is understood to specify a target object file. ! Since `-E' is not implied, `-MD' can be used to generate a dependency output file as a side-effect of the compilation process. ! `-MMD' ! Like `-MD' except mention only user header files, not system ! header files. ! `-x c' ! `-x c++' ! `-x objective-c' ! `-x assembler-with-cpp' Specify the source language: C, C++, Objective-C, or assembly. ! This has nothing to do with standards conformance or extensions; ! it merely selects which base syntax to expect. If you give none ! of these options, cpp will deduce the language from the extension ! of the source file: `.c', `.cc', `.m', or `.S'. Some other common extensions for C++ and assembly are also recognized. If cpp does not recognize the extension, it will treat the file as C; this is the most generic mode. ! _Note:_ Previous versions of cpp accepted a `-lang' option which selected both the language and the standards conformance level. ! This option has been removed, because it conflicts with the `-l' option. ! `-std=STANDARD' ! `-ansi' Specify the standard to which the code should conform. Currently CPP knows about C and C++ standards; others may be added in the future. STANDARD may be one of: ! `c90' ! `c89' ! `iso9899:1990' ! The ISO C standard from 1990. `c90' is the customary shorthand for this version of the standard. ! The `-ansi' option is equivalent to `-std=c90'. ! `iso9899:199409' The 1990 C standard, as amended in 1994. ! `iso9899:1999' ! `c99' ! `iso9899:199x' ! `c9x' The revised ISO C standard, published in December 1999. Before publication, this was known as C9X. ! `iso9899:2011' ! `c11' ! `c1x' The revised ISO C standard, published in December 2011. Before publication, this was known as C1X. ! `gnu90' ! `gnu89' The 1990 C standard plus GNU extensions. This is the default. ! `gnu99' ! `gnu9x' The 1999 C standard plus GNU extensions. ! `gnu11' ! `gnu1x' The 2011 C standard plus GNU extensions. ! `c++98' The 1998 ISO C++ standard plus amendments. ! `gnu++98' ! The same as `-std=c++98' plus GNU extensions. This is the default for C++ code. ! `-I-' ! Split the include path. Any directories specified with `-I' ! options before `-I-' are searched only for headers requested with ! `#include "FILE"'; they are not searched for `#include '. ! If additional directories are specified with `-I' options after ! the `-I-', those directories are searched for all `#include' directives. ! In addition, `-I-' inhibits the use of the directory of the current ! file directory as the first search directory for `#include "FILE"'. *Note Search Path::. This option has been deprecated. ! `-nostdinc' Do not search the standard system directories for header files. ! Only the directories you have specified with `-I' options (and the directory of the current file, if appropriate) are searched. ! `-nostdinc++' Do not search for header files in the C++-specific standard directories, but do still search the other standard directories. (This option is used when building the C++ library.) ! `-include FILE' ! Process FILE as if `#include "file"' appeared as the first line of ! the primary source file. However, the first directory searched ! for FILE is the preprocessor's working directory _instead of_ the directory containing the main source file. If not found there, it ! is searched for in the remainder of the `#include "..."' search chain as normal. ! If multiple `-include' options are given, the files are included ! in the order they appear on the command line. ! `-imacros FILE' ! Exactly like `-include', except that any output produced by scanning FILE is thrown away. Macros it defines remain defined. This allows you to acquire all the macros from a header without also processing its declarations. ! All files specified by `-imacros' are processed before all files ! specified by `-include'. ! `-idirafter DIR' Search DIR for header files, but do it _after_ all directories ! specified with `-I' and the standard system directories have been exhausted. DIR is treated as a system include directory. If DIR ! begins with `=', then the `=' will be replaced by the sysroot ! prefix; see `--sysroot' and `-isysroot'. ! `-iprefix PREFIX' ! Specify PREFIX as the prefix for subsequent `-iwithprefix' ! options. If the prefix represents a directory, you should include ! the final `/'. ! `-iwithprefix DIR' ! `-iwithprefixbefore DIR' ! Append DIR to the prefix specified previously with `-iprefix', and add the resulting directory to the include search path. ! `-iwithprefixbefore' puts it in the same place `-I' would; ! `-iwithprefix' puts it where `-idirafter' would. ! `-isysroot DIR' ! This option is like the `--sysroot' option, but applies only to header files (except for Darwin targets, where it applies to both ! header files and libraries). See the `--sysroot' option for more information. ! `-imultilib DIR' Use DIR as a subdirectory of the directory containing target-specific C++ headers. ! `-isystem DIR' Search DIR for header files, after all directories specified by ! `-I' but before the standard system directories. Mark it as a system directory, so that it gets the same special treatment as is applied to the standard system directories. *Note System ! Headers::. If DIR begins with `=', then the `=' will be replaced ! by the sysroot prefix; see `--sysroot' and `-isysroot'. ! `-iquote DIR' ! Search DIR only for header files requested with `#include "FILE"'; ! they are not searched for `#include ', before all ! directories specified by `-I' and before the standard system ! directories. *Note Search Path::. If DIR begins with `=', then ! the `=' will be replaced by the sysroot prefix; see `--sysroot' ! and `-isysroot'. ! `-fdirectives-only' When preprocessing, handle directives, but do not expand macros. ! The option's behavior depends on the `-E' and `-fpreprocessed' options. ! With `-E', preprocessing is limited to the handling of directives ! such as `#define', `#ifdef', and `#error'. Other preprocessor ! operations, such as macro expansion and trigraph conversion are ! not performed. In addition, the `-dD' option is implicitly ! enabled. ! With `-fpreprocessed', predefinition of command line and most ! builtin macros is disabled. Macros such as `__LINE__', which are contextually dependent, are handled normally. This enables ! compilation of files previously preprocessed with `-E -fdirectives-only'. ! With both `-E' and `-fpreprocessed', the rules for ! `-fpreprocessed' take precedence. This enables full preprocessing ! of files previously preprocessed with `-E -fdirectives-only'. ! `-fdollars-in-identifiers' ! Accept `$' in identifiers. *Note Identifier characters::. ! `-fextended-identifiers' Accept universal character names in identifiers. This option is experimental; in a future version of GCC, it will be enabled by default for C99 and C++. ! `-fno-canonical-system-headers' When preprocessing, do not shorten system header paths with canonicalization. ! `-fpreprocessed' Indicate to the preprocessor that the input file has already been preprocessed. This suppresses things like macro expansion, trigraph conversion, escaped newline splicing, and processing of most directives. The preprocessor still recognizes and removes ! comments, so that you can pass a file preprocessed with `-C' to ! the compiler without problems. In this mode the integrated preprocessor is little more than a tokenizer for the front ends. ! `-fpreprocessed' is implicit if the input file has one of the ! extensions `.i', `.ii' or `.mi'. These are the extensions that ! GCC uses for preprocessed files created by `-save-temps'. ! `-ftabstop=WIDTH' Set the distance between tab stops. This helps the preprocessor report correct column numbers in warnings or errors, even if tabs appear on the line. If the value is less than 1 or greater than 100, the option is ignored. The default is 8. ! `-fdebug-cpp' ! This option is only useful for debugging GCC. When used with ! `-E', dumps debugging information about location maps. Every ! token in the output is preceded by the dump of the map its location ! belongs to. The dump of the map holding the location of a token ! would be: ! {`P':`/file/path';`F':`/includer/path';`L':LINE_NUM;`C':COL_NUM;`S':SYSTEM_HEADER_P;`M':MAP_ADDRESS;`E':MACRO_EXPANSION_P,`loc':LOCATION} ! When used without `-E', this option has no effect. ! `-ftrack-macro-expansion[=LEVEL]' ! Track locations of tokens across macro expansions. This allows the compiler to emit diagnostic about the current macro expansion stack ! when a compilation error occurs in a macro expansion. Using this ! option makes the preprocessor and the compiler consume more ! memory. The LEVEL parameter can be used to choose the level of ! precision of token location tracking thus decreasing the memory ! consumption if necessary. Value `0' of LEVEL de-activates this ! option just as if no `-ftrack-macro-expansion' was present on the ! command line. Value `1' tracks tokens locations in a degraded mode ! for the sake of minimal memory overhead. In this mode all tokens ! resulting from the expansion of an argument of a function-like ! macro have the same location. Value `2' tracks tokens locations ! completely. This value is the most memory hungry. When this ! option is given no argument, the default parameter value is `2'. Note that -ftrack-macro-expansion=2 is activated by default. ! `-fexec-charset=CHARSET' Set the execution character set, used for string and character constants. The default is UTF-8. CHARSET can be any encoding ! supported by the system's `iconv' library routine. ! `-fwide-exec-charset=CHARSET' Set the wide execution character set, used for wide string and character constants. The default is UTF-32 or UTF-16, whichever ! corresponds to the width of `wchar_t'. As with `-fexec-charset', ! CHARSET can be any encoding supported by the system's `iconv' library routine; however, you will have problems with encodings ! that do not fit exactly in `wchar_t'. ! `-finput-charset=CHARSET' Set the input character set, used for translation from the ! character set of the input file to the source character set used ! by GCC. If the locale does not specify, or GCC cannot get this information from the locale, the default is UTF-8. This can be overridden by either the locale or this command line option. Currently the command line option takes precedence if there's a conflict. CHARSET can be any encoding supported by the system's ! `iconv' library routine. ! `-fworking-directory' Enable generation of linemarkers in the preprocessor output that will let the compiler know the current working directory at the time of preprocessing. When this option is enabled, the preprocessor will emit, after the initial linemarker, a second linemarker with the current working directory followed by two slashes. GCC will use this directory, when it's present in the ! preprocessed input, as the directory emitted as the current ! working directory in some debugging information formats. This ! option is implicitly enabled if debugging information is enabled, ! but this can be inhibited with the negated form ! `-fno-working-directory'. If the `-P' flag is present in the ! command line, this option has no effect, since no `#line' ! directives are emitted whatsoever. ! `-fno-show-column' Do not print column numbers in diagnostics. This may be necessary if diagnostics are being scanned by a program that does not ! understand the column numbers, such as `dejagnu'. ! `-A PREDICATE=ANSWER' Make an assertion with the predicate PREDICATE and answer ANSWER. ! This form is preferred to the older form `-A PREDICATE(ANSWER)', which is still supported, because it does not use shell special characters. *Note Obsolete Features::. ! `-A -PREDICATE=ANSWER' Cancel an assertion with the predicate PREDICATE and answer ANSWER. ! `-dCHARS' ! CHARS is a sequence of one or more of the following characters, ! and must not be preceded by a space. Other characters are ! interpreted by the compiler proper, or reserved for future ! versions of GCC, and so are silently ignored. If you specify ! characters whose behavior conflicts, the result is undefined. ! `M' ! Instead of the normal output, generate a list of `#define' directives for all the macros defined during the execution of ! the preprocessor, including predefined macros. This gives ! you a way of finding out what is predefined in your version ! of the preprocessor. Assuming you have no file `foo.h', the ! command touch foo.h; cpp -dM foo.h will show all the predefined macros. ! If you use `-dM' without the `-E' option, `-dM' is ! interpreted as a synonym for `-fdump-rtl-mach'. *Note ! Debugging Options: (gcc)Debugging Options. ! `D' ! Like `M' except in two respects: it does _not_ include the ! predefined macros, and it outputs _both_ the `#define' directives and the result of preprocessing. Both kinds of output go to the standard output file. ! `N' ! Like `D', but emit only the macro names, not their expansions. ! `I' ! Output `#include' directives in addition to the result of preprocessing. ! `U' ! Like `D' except that only macros that are expanded, or whose definedness is tested in preprocessor directives, are output; the output is delayed until the use or test of the macro; and ! `#undef' directives are also output for macros tested but undefined at the time. ! `-P' Inhibit generation of linemarkers in the output from the preprocessor. This might be useful when running the preprocessor on something that is not C code, and will be sent to a program which might be confused by the linemarkers. *Note Preprocessor Output::. ! `-C' Do not discard comments. All comments are passed through to the ! output file, except for comments in processed directives, which ! are deleted along with the directive. ! You should be prepared for side effects when using `-C'; it causes the preprocessor to treat comments as tokens in their own right. For example, comments appearing at the start of what would be a directive line have the effect of turning that line into an ordinary source line, since the first token on the line is no ! longer a `#'. ! `-CC' Do not discard comments, including during macro expansion. This is ! like `-C', except that comments contained within macros are also passed through to the output file where the macro is expanded. ! In addition to the side-effects of the `-C' option, the `-CC' ! option causes all C++-style comments inside a macro to be ! converted to C-style comments. This is to prevent later use of ! that macro from inadvertently commenting out the remainder of the ! source line. ! The `-CC' option is generally used to support lint comments. ! `-traditional-cpp' Try to imitate the behavior of old-fashioned C preprocessors, as opposed to ISO C preprocessors. *Note Traditional Mode::. ! `-trigraphs' Process trigraph sequences. *Note Initial processing::. ! `-remap' Enable special code to work around file systems which only permit very short file names, such as MS-DOS. ! `--help' ! `--target-help' Print text describing all the command line options instead of preprocessing anything. ! `-v' Verbose mode. Print out GNU CPP's version number at the beginning of execution, and report the final form of the include path. ! `-H' Print the name of each header file used, in addition to other normal activities. Each name is indented to show how deep in the ! `#include' stack it is. Precompiled header files are also ! printed, even if they are found to be invalid; an invalid ! precompiled header file is printed with `...x' and a valid one ! with `...!' . ! `-version' ! `--version' Print out GNU CPP's version number. With one dash, proceed to preprocess as normal. With two dashes, exit immediately. --- 4220,4656 ---- test.h: ! '-MT TARGET' ! Change the target of the rule emitted by dependency generation. By default CPP takes the name of the main input file, deletes any ! directory components and any file suffix such as '.c', and appends the platform's usual object suffix. The result is the target. ! An '-MT' option will set the target to be exactly the string you specify. If you want multiple targets, you can specify them as a ! single argument to '-MT', or use multiple '-MT' options. ! For example, '-MT '$(objpfx)foo.o'' might give $(objpfx)foo.o: foo.c ! '-MQ TARGET' ! ! Same as '-MT', but it quotes any characters which are special to ! Make. '-MQ '$(objpfx)foo.o'' gives $$(objpfx)foo.o: foo.c The default target is automatically quoted, as if it were given ! with '-MQ'. ! '-MD' ! '-MD' is equivalent to '-M -MF FILE', except that '-E' is not ! implied. The driver determines FILE based on whether an '-o' ! option is given. If it is, the driver uses its argument but with a ! suffix of '.d', otherwise it takes the name of the input file, ! removes any directory components and suffix, and applies a '.d' suffix. ! If '-MD' is used in conjunction with '-E', any '-o' switch is understood to specify the dependency output file (*note -MF: ! dashMF.), but if used without '-E', each '-o' is understood to specify a target object file. ! Since '-E' is not implied, '-MD' can be used to generate a dependency output file as a side-effect of the compilation process. ! '-MMD' ! Like '-MD' except mention only user header files, not system header ! files. ! '-x c' ! '-x c++' ! '-x objective-c' ! '-x assembler-with-cpp' Specify the source language: C, C++, Objective-C, or assembly. ! This has nothing to do with standards conformance or extensions; it ! merely selects which base syntax to expect. If you give none of ! these options, cpp will deduce the language from the extension of ! the source file: '.c', '.cc', '.m', or '.S'. Some other common extensions for C++ and assembly are also recognized. If cpp does not recognize the extension, it will treat the file as C; this is the most generic mode. ! _Note:_ Previous versions of cpp accepted a '-lang' option which selected both the language and the standards conformance level. ! This option has been removed, because it conflicts with the '-l' option. ! '-std=STANDARD' ! '-ansi' Specify the standard to which the code should conform. Currently CPP knows about C and C++ standards; others may be added in the future. STANDARD may be one of: ! 'c90' ! 'c89' ! 'iso9899:1990' ! The ISO C standard from 1990. 'c90' is the customary shorthand for this version of the standard. ! The '-ansi' option is equivalent to '-std=c90'. ! 'iso9899:199409' The 1990 C standard, as amended in 1994. ! 'iso9899:1999' ! 'c99' ! 'iso9899:199x' ! 'c9x' The revised ISO C standard, published in December 1999. Before publication, this was known as C9X. ! 'iso9899:2011' ! 'c11' ! 'c1x' The revised ISO C standard, published in December 2011. Before publication, this was known as C1X. ! 'gnu90' ! 'gnu89' The 1990 C standard plus GNU extensions. This is the default. ! 'gnu99' ! 'gnu9x' The 1999 C standard plus GNU extensions. ! 'gnu11' ! 'gnu1x' The 2011 C standard plus GNU extensions. ! 'c++98' The 1998 ISO C++ standard plus amendments. ! 'gnu++98' ! The same as '-std=c++98' plus GNU extensions. This is the default for C++ code. ! '-I-' ! Split the include path. Any directories specified with '-I' ! options before '-I-' are searched only for headers requested with ! '#include "FILE"'; they are not searched for '#include '. If ! additional directories are specified with '-I' options after the ! '-I-', those directories are searched for all '#include' directives. ! In addition, '-I-' inhibits the use of the directory of the current ! file directory as the first search directory for '#include "FILE"'. *Note Search Path::. This option has been deprecated. ! '-nostdinc' Do not search the standard system directories for header files. ! Only the directories you have specified with '-I' options (and the directory of the current file, if appropriate) are searched. ! '-nostdinc++' Do not search for header files in the C++-specific standard directories, but do still search the other standard directories. (This option is used when building the C++ library.) ! '-include FILE' ! Process FILE as if '#include "file"' appeared as the first line of ! the primary source file. However, the first directory searched for ! FILE is the preprocessor's working directory _instead of_ the directory containing the main source file. If not found there, it ! is searched for in the remainder of the '#include "..."' search chain as normal. ! If multiple '-include' options are given, the files are included in ! the order they appear on the command line. ! '-imacros FILE' ! Exactly like '-include', except that any output produced by scanning FILE is thrown away. Macros it defines remain defined. This allows you to acquire all the macros from a header without also processing its declarations. ! All files specified by '-imacros' are processed before all files ! specified by '-include'. ! '-idirafter DIR' Search DIR for header files, but do it _after_ all directories ! specified with '-I' and the standard system directories have been exhausted. DIR is treated as a system include directory. If DIR ! begins with '=', then the '=' will be replaced by the sysroot ! prefix; see '--sysroot' and '-isysroot'. ! '-iprefix PREFIX' ! Specify PREFIX as the prefix for subsequent '-iwithprefix' options. ! If the prefix represents a directory, you should include the final ! '/'. ! '-iwithprefix DIR' ! '-iwithprefixbefore DIR' ! Append DIR to the prefix specified previously with '-iprefix', and add the resulting directory to the include search path. ! '-iwithprefixbefore' puts it in the same place '-I' would; ! '-iwithprefix' puts it where '-idirafter' would. ! '-isysroot DIR' ! This option is like the '--sysroot' option, but applies only to header files (except for Darwin targets, where it applies to both ! header files and libraries). See the '--sysroot' option for more information. ! '-imultilib DIR' Use DIR as a subdirectory of the directory containing target-specific C++ headers. ! '-isystem DIR' Search DIR for header files, after all directories specified by ! '-I' but before the standard system directories. Mark it as a system directory, so that it gets the same special treatment as is applied to the standard system directories. *Note System ! Headers::. If DIR begins with '=', then the '=' will be replaced ! by the sysroot prefix; see '--sysroot' and '-isysroot'. ! '-iquote DIR' ! Search DIR only for header files requested with '#include "FILE"'; ! they are not searched for '#include ', before all directories ! specified by '-I' and before the standard system directories. ! *Note Search Path::. If DIR begins with '=', then the '=' will be ! replaced by the sysroot prefix; see '--sysroot' and '-isysroot'. ! '-fdirectives-only' When preprocessing, handle directives, but do not expand macros. ! The option's behavior depends on the '-E' and '-fpreprocessed' options. ! With '-E', preprocessing is limited to the handling of directives ! such as '#define', '#ifdef', and '#error'. Other preprocessor ! operations, such as macro expansion and trigraph conversion are not ! performed. In addition, the '-dD' option is implicitly enabled. ! With '-fpreprocessed', predefinition of command line and most ! builtin macros is disabled. Macros such as '__LINE__', which are contextually dependent, are handled normally. This enables ! compilation of files previously preprocessed with '-E -fdirectives-only'. ! With both '-E' and '-fpreprocessed', the rules for '-fpreprocessed' ! take precedence. This enables full preprocessing of files ! previously preprocessed with '-E -fdirectives-only'. ! '-fdollars-in-identifiers' ! Accept '$' in identifiers. *Note Identifier characters::. ! '-fextended-identifiers' Accept universal character names in identifiers. This option is experimental; in a future version of GCC, it will be enabled by default for C99 and C++. ! '-fno-canonical-system-headers' When preprocessing, do not shorten system header paths with canonicalization. ! '-fpreprocessed' Indicate to the preprocessor that the input file has already been preprocessed. This suppresses things like macro expansion, trigraph conversion, escaped newline splicing, and processing of most directives. The preprocessor still recognizes and removes ! comments, so that you can pass a file preprocessed with '-C' to the ! compiler without problems. In this mode the integrated preprocessor is little more than a tokenizer for the front ends. ! '-fpreprocessed' is implicit if the input file has one of the ! extensions '.i', '.ii' or '.mi'. These are the extensions that GCC ! uses for preprocessed files created by '-save-temps'. ! '-ftabstop=WIDTH' Set the distance between tab stops. This helps the preprocessor report correct column numbers in warnings or errors, even if tabs appear on the line. If the value is less than 1 or greater than 100, the option is ignored. The default is 8. ! '-fdebug-cpp' ! This option is only useful for debugging GCC. When used with '-E', ! dumps debugging information about location maps. Every token in ! the output is preceded by the dump of the map its location belongs ! to. The dump of the map holding the location of a token would be: ! {'P':/file/path;'F':/includer/path;'L':LINE_NUM;'C':COL_NUM;'S':SYSTEM_HEADER_P;'M':MAP_ADDRESS;'E':MACRO_EXPANSION_P,'loc':LOCATION} ! When used without '-E', this option has no effect. ! '-ftrack-macro-expansion[=LEVEL]' ! Track locations of tokens across macro expansions. This allows the compiler to emit diagnostic about the current macro expansion stack ! when a compilation error occurs in a macro expansion. Using this ! option makes the preprocessor and the compiler consume more memory. ! The LEVEL parameter can be used to choose the level of precision of ! token location tracking thus decreasing the memory consumption if ! necessary. Value '0' of LEVEL de-activates this option just as if ! no '-ftrack-macro-expansion' was present on the command line. ! Value '1' tracks tokens locations in a degraded mode for the sake ! of minimal memory overhead. In this mode all tokens resulting from ! the expansion of an argument of a function-like macro have the same ! location. Value '2' tracks tokens locations completely. This ! value is the most memory hungry. When this option is given no ! argument, the default parameter value is '2'. Note that -ftrack-macro-expansion=2 is activated by default. ! '-fexec-charset=CHARSET' Set the execution character set, used for string and character constants. The default is UTF-8. CHARSET can be any encoding ! supported by the system's 'iconv' library routine. ! '-fwide-exec-charset=CHARSET' Set the wide execution character set, used for wide string and character constants. The default is UTF-32 or UTF-16, whichever ! corresponds to the width of 'wchar_t'. As with '-fexec-charset', ! CHARSET can be any encoding supported by the system's 'iconv' library routine; however, you will have problems with encodings ! that do not fit exactly in 'wchar_t'. ! '-finput-charset=CHARSET' Set the input character set, used for translation from the ! character set of the input file to the source character set used by ! GCC. If the locale does not specify, or GCC cannot get this information from the locale, the default is UTF-8. This can be overridden by either the locale or this command line option. Currently the command line option takes precedence if there's a conflict. CHARSET can be any encoding supported by the system's ! 'iconv' library routine. ! '-fworking-directory' Enable generation of linemarkers in the preprocessor output that will let the compiler know the current working directory at the time of preprocessing. When this option is enabled, the preprocessor will emit, after the initial linemarker, a second linemarker with the current working directory followed by two slashes. GCC will use this directory, when it's present in the ! preprocessed input, as the directory emitted as the current working ! directory in some debugging information formats. This option is ! implicitly enabled if debugging information is enabled, but this ! can be inhibited with the negated form '-fno-working-directory'. ! If the '-P' flag is present in the command line, this option has no ! effect, since no '#line' directives are emitted whatsoever. ! '-fno-show-column' Do not print column numbers in diagnostics. This may be necessary if diagnostics are being scanned by a program that does not ! understand the column numbers, such as 'dejagnu'. ! '-A PREDICATE=ANSWER' Make an assertion with the predicate PREDICATE and answer ANSWER. ! This form is preferred to the older form '-A PREDICATE(ANSWER)', which is still supported, because it does not use shell special characters. *Note Obsolete Features::. ! '-A -PREDICATE=ANSWER' Cancel an assertion with the predicate PREDICATE and answer ANSWER. ! '-dCHARS' ! CHARS is a sequence of one or more of the following characters, and ! must not be preceded by a space. Other characters are interpreted ! by the compiler proper, or reserved for future versions of GCC, and ! so are silently ignored. If you specify characters whose behavior ! conflicts, the result is undefined. ! 'M' ! Instead of the normal output, generate a list of '#define' directives for all the macros defined during the execution of ! the preprocessor, including predefined macros. This gives you ! a way of finding out what is predefined in your version of the ! preprocessor. Assuming you have no file 'foo.h', the command touch foo.h; cpp -dM foo.h will show all the predefined macros. ! If you use '-dM' without the '-E' option, '-dM' is interpreted ! as a synonym for '-fdump-rtl-mach'. *Note (gcc)Debugging ! Options::. ! 'D' ! Like 'M' except in two respects: it does _not_ include the ! predefined macros, and it outputs _both_ the '#define' directives and the result of preprocessing. Both kinds of output go to the standard output file. ! 'N' ! Like 'D', but emit only the macro names, not their expansions. ! 'I' ! Output '#include' directives in addition to the result of preprocessing. ! 'U' ! Like 'D' except that only macros that are expanded, or whose definedness is tested in preprocessor directives, are output; the output is delayed until the use or test of the macro; and ! '#undef' directives are also output for macros tested but undefined at the time. ! '-P' Inhibit generation of linemarkers in the output from the preprocessor. This might be useful when running the preprocessor on something that is not C code, and will be sent to a program which might be confused by the linemarkers. *Note Preprocessor Output::. ! '-C' Do not discard comments. All comments are passed through to the ! output file, except for comments in processed directives, which are ! deleted along with the directive. ! You should be prepared for side effects when using '-C'; it causes the preprocessor to treat comments as tokens in their own right. For example, comments appearing at the start of what would be a directive line have the effect of turning that line into an ordinary source line, since the first token on the line is no ! longer a '#'. ! '-CC' Do not discard comments, including during macro expansion.

This is to prevent later use of that macro ! from inadvertently commenting out the remainder of the source line. ! The '-CC' option is generally used to support lint comments. ! '-traditional-cpp' Try to imitate the behavior of old-fashioned C preprocessors, as opposed to ISO C preprocessors. *Note Traditional Mode::. ! '-trigraphs' Process trigraph sequences. *Note Initial processing::. ! '-remap' Enable special code to work around file systems which only permit very short file names, such as MS-DOS. ! '--help' ! '--target-help' Print text describing all the command line options instead of preprocessing anything. ! '-v' Verbose mode. Print out GNU CPP's version number at the beginning of execution, and report the final form of the include path. ! '-H' Print the name of each header file used, in addition to other normal activities. Each name is indented to show how deep in the ! '#include' stack it is. Precompiled header files are also printed, ! even if they are found to be invalid; an invalid precompiled header ! file is printed with '...x' and a valid one with '...!' . ! '-version' !

You can use them to specify d *** 4698,4757 **** when searching for include files, or to control dependency output. Note that you can also specify places to search using options such as ! `-I', and control dependency output with options like `-M' (*note Invocation::). These take precedence over environment variables, which in turn take precedence over the configuration of GCC. ! `CPATH' ! `C_INCLUDE_PATH' ! `CPLUS_INCLUDE_PATH' ! `OBJC_INCLUDE_PATH' Each variable's value is a list of directories separated by a ! special character, much like `PATH', in which to look for header ! files. The special character, `PATH_SEPARATOR', is target-dependent and determined at GCC build time. For Microsoft Windows-based targets it is a semicolon, and for almost all other targets it is a colon. ! `CPATH' specifies a list of directories to be searched as if ! specified with `-I', but after any paths given with `-I' options ! on the command line. This environment variable is used regardless ! of which language is being preprocessed. The remaining environment variables apply only when preprocessing the particular language indicated. Each specifies a list of ! directories to be searched as if specified with `-isystem', but ! after any paths given with `-isystem' options on the command line. In all these variables, an empty element instructs the compiler to ! search its current working directory. Empty elements can appear ! at the beginning or end of a path. For instance, if the value of ! `CPATH' is `:/special/include', that has the same effect as ! `-I. -I/special/include'. See also *note Search Path::. ! `DEPENDENCIES_OUTPUT' If this variable is set, its value specifies how to output dependencies for Make based on the non-system header files processed by the compiler. System header files are ignored in the dependency output. ! The value of `DEPENDENCIES_OUTPUT' can be just a file name, in which case the Make rules are written to that file, guessing the target name from the source file name. Or the value can have the ! form `FILE TARGET', in which case the rules are written to file FILE using TARGET as the target name. In other words, this environment variable is equivalent to ! combining the options `-MM' and `-MF' (*note Invocation::), with ! an optional `-MT' switch too. ! `SUNPRO_DEPENDENCIES' !

The job of `_cpp_lex_direct' is simply to lex a token. It is not responsible for issues like directive handling, returning lookahead tokens directly, multiple-include optimization, or conditional block ! skipping. It necessarily has a minor ro^le to play in memory ! management of lexed lines. I discuss these issues in a separate section ! (*note Lexing a line::). The lexer places the token it lexes into storage pointed to by the ! variable `cur_token', and then increments it. This variable is important for correct diagnostic positioning. Unless a specific line and column are passed to the diagnostic routines, they will examine the ! `line' and `col' values of the token just before the location that ! `cur_token' points to, and use that location to report the diagnostic. The lexer does not consider whitespace to be a token in its own right. If whitespace (other than a new line) precedes a token, it sets ! the `PREV_WHITE' bit in the token's flags. Each token has its `line' ! and `col' variables set to the line and column of the first character ! of the token. This line number is the line number in the translation ! unit, and can be converted to a source (file, line) pair using the line ! map code. ! The first token on a logical, i.e. unescaped, line has the flag ! `BOL' set for beginning-of-line. This flag is intended for internal ! use, both to distinguish a `#' that begins a directive from one that ! doesn't, and to generate a call-back to clients that want to be ! notified about the start of every non-directive line with tokens on it. ! Clients cannot reliably determine this for themselves: the first token ! might be a macro, and the tokens of a macro expansion do not have the ! `BOL' flag set. The macro expansion may even be empty, and the next ! token on the line certainly won't have the `BOL' flag set. New lines are treated specially; exactly how the lexer handles them is context-dependent. The C standard mandates that directives are terminated by the first unescaped newline character, even if it appears in the middle of a macro expansion. Therefore, if the state variable ! `in_directive' is set, the lexer returns a `CPP_EOF' token, which is ! normally used to indicate end-of-file, to indicate end-of-directive. ! In a directive a `CPP_EOF' token never means end-of-file. ! Conveniently, if the caller was `collect_args', it already handles ! `CPP_EOF' as if it were end-of-file, and reports an error about an ! unterminated macro argument list. The C standard also specifies that a new line in the middle of the arguments to a macro is treated as whitespace. This white space is important in case the macro argument is stringified. The state variable ! `parsing_args' is nonzero when the preprocessor is collecting the arguments to a macro call. It is set to 1 when looking for the opening parenthesis to a function-like macro, and 2 when collecting the actual arguments up to the closing parenthesis, since these two cases need to be distinguished sometimes. One such time is here: the lexer sets the ! `PREV_WHITE' flag of a token if it meets a new line when `parsing_args' is set to 2. It doesn't set it if it meets a new line when ! `parsing_args' is 1, since then code like #define foo() bar foo baz ! would be output with an erroneous space before `baz': foo baz --- 122,187 ---- before processing them.

The lexer is written to treat each of `\r', `\n', `\r\n' and `\n\r' as a single new line indicator. This allows it to transparently preprocess MS-DOS, Macintosh and Unix files without their needing to pass through a special filter beforehand. ! We also decided to treat a backslash, either `\' or the trigraph ! `??/', separated from one of the above newline indicators by ! non-comment whitespace only, as intending to escape the newline. It ! tends to be a typing mistake, and cannot reasonably be mistaken for ! anything else in any of the C-family grammars. Since handling it this ! way is not strictly conforming to the ISO standard, the library issues a ! warning wherever it encounters it. Handling newlines like this is made simpler by doing it in one place ! only. The function `handle_newline' takes care of all newline ! characters, and `skip_escaped_newlines' takes care of arbitrarily long ! sequences of escaped newlines, deferring to `handle_newline' to handle the newlines themselves. The most painful aspect of lexing ISO-standard C and C++ is handling trigraphs and backlash-escaped newlines. Trigraphs are processed before any interpretation of the meaning of a character is made, and unfortunately there is a trigraph representation for a backslash, so it ! is possible for the trigraph `??/' to introduce an escaped newline. Escaped newlines are tedious because theoretically they can occur ! anywhere--between the `+' and `=' of the `+=' token, within the ! characters of an identifier, and even between the `*' and `/' that terminates a comment. Moreover, you cannot be sure there is just one--there might be an arbitrarily long sequence of them. ! So, for example, the routine that lexes a number, `parse_number', cannot assume that it can scan forwards until the first non-number ! character and be done with it, because this could be the `\' ! introducing an escaped newline, or the `?' introducing the trigraph ! sequence that represents the `\' of an escaped newline. If it ! encounters a `?' or `\', it calls `skip_escaped_newlines' to skip over ! any potential escaped newlines before checking whether the number has ! been finished. ! Similarly code in the main body of `_cpp_lex_direct' cannot simply ! check for a `=' after a `+' character to determine whether it has a ! `+=' token; it needs to be prepared for an escaped newline of some ! sort. Such cases use the function `get_effective_char', which returns ! the first character after any intervening escaped newlines. The lexer needs to keep track of the correct column position, ! including counting tabs as specified by the `-ftabstop=' option. This should be done even within C-style comments; they can appear in the middle of a line, and we want to report diagnostics in the correct position for text appearing after the end of the comment. ! Some identifiers, such as `__VA_ARGS__' and poisoned identifiers, ! may be invalid and require a diagnostic. However, if they appear in a ! macro expansion we don't want to complain with each use of the macro. ! It is therefore best to catch them during the lexing stage, in ! `parse_identifier'. In both cases, whether a diagnostic is needed or not is dependent upon the lexer's state. For example, we don't want to issue a diagnostic for re-poisoning a poisoned identifier, or for using ! `__VA_ARGS__' in the expansion of a variable-argument macro. Therefore ! `parse_identifier' makes use of state flags to determine whether a diagnostic is appropriate. Since we change state on a per-token basis, and don't lex whole lines at a time, this is not a problem. Another place where state flags are used to change behavior is whilst ! lexing header names. Normally, a `<' would be lexed as a single token. ! After a `#include' directive, though, it should be lexed as a single ! token as far as the nearest `>' character. Note that we don't allow ! the terminators of header names to be escaped; the first `"' or `>' terminates the header name. Interpretation of some character sequences depends upon whether we are lexing C, C++ or Objective-C, and on the revision of the standard in ! force. For example, `::' is a single token in C++, but in C it is two ! separate `:' tokens and almost certainly a syntax error. Such cases ! are handled by `_cpp_lex_direct' based upon command-line flags stored ! in the `cpp_options' structure. Once a token has been lexed, it leads an independent existence. The spelling of numbers, identifiers and strings is copied to permanent storage from the original input buffer, so a token remains valid and ! correct even if its source buffer is freed with `_cpp_pop_buffer'.

The lexer is written to treat each of '\r', '\n', '\r\n' and '\n\r' as a single new line indicator. This allows it to transparently preprocess MS-DOS, Macintosh and Unix files without their needing to pass through a special filter beforehand. ! We also decided to treat a backslash, either '\' or the trigraph ! '??/', separated from one of the above newline indicators by non-comment ! whitespace only, as intending to escape the newline. It tends to be a ! typing mistake, and cannot reasonably be mistaken for anything else in ! any of the C-family grammars. Since handling it this way is not ! strictly conforming to the ISO standard, the library issues a warning ! wherever it encounters it. Handling newlines like this is made simpler by doing it in one place ! only. The function 'handle_newline' takes care of all newline ! characters, and 'skip_escaped_newlines' takes care of arbitrarily long ! sequences of escaped newlines, deferring to 'handle_newline' to handle the newlines themselves. The most painful aspect of lexing ISO-standard C and C++ is handling trigraphs and backlash-escaped newlines. Trigraphs are processed before any interpretation of the meaning of a character is made, and unfortunately there is a trigraph representation for a backslash, so it ! is possible for the trigraph '??/' to introduce an escaped newline. Escaped newlines are tedious because theoretically they can occur ! anywhere--between the '+' and '=' of the '+=' token, within the ! characters of an identifier, and even between the '*' and '/' that terminates a comment. Moreover, you cannot be sure there is just one--there might be an arbitrarily long sequence of them. ! So, for example, the routine that lexes a number, 'parse_number', cannot assume that it can scan forwards until the first non-number ! character and be done with it, because this could be the '\' introducing ! an escaped newline, or the '?' introducing the trigraph sequence that ! represents the '\' of an escaped newline. If it encounters a '?' or ! '\', it calls 'skip_escaped_newlines' to skip over any potential escaped ! newlines before checking whether the number has been finished. ! Similarly code in the main body of '_cpp_lex_direct' cannot simply ! check for a '=' after a '+' character to determine whether it has a '+=' ! token; it needs to be prepared for an escaped newline of some sort. ! Such cases use the function 'get_effective_char', which returns the ! first character after any intervening escaped newlines. The lexer needs to keep track of the correct column position, ! including counting tabs as specified by the '-ftabstop=' option. This should be done even within C-style comments; they can appear in the middle of a line, and we want to report diagnostics in the correct position for text appearing after the end of the comment. ! Some identifiers, such as '__VA_ARGS__' and poisoned identifiers, may ! be invalid and require a diagnostic. However, if they appear in a macro ! expansion we don't want to complain with each use of the macro. It is ! therefore best to catch them during the lexing stage, in ! 'parse_identifier'. In both cases, whether a diagnostic is needed or not is dependent upon the lexer's state. For example, we don't want to issue a diagnostic for re-poisoning a poisoned identifier, or for using ! '__VA_ARGS__' in the expansion of a variable-argument macro. Therefore ! 'parse_identifier' makes use of state flags to determine whether a diagnostic is appropriate. Since we change state on a per-token basis, and don't lex whole lines at a time, this is not a problem. Another place where state flags are used to change behavior is whilst ! lexing header names. Normally, a '<' would be lexed as a single token. ! After a '#include' directive, though, it should be lexed as a single ! token as far as the nearest '>' character. Note that we don't allow the ! terminators of header names to be escaped; the first '"' or '>' terminates the header name. Interpretation of some character sequences depends upon whether we are lexing C, C++ or Objective-C, and on the revision of the standard in ! force. For example, '::' is a single token in C++, but in C it is two ! separate ':' tokens and almost certainly a syntax error. Such cases are ! handled by '_cpp_lex_direct' based upon command-line flags stored in the ! 'cpp_options' structure. Once a token has been lexed, it leads an independent existence. The spelling of numbers, identifiers and strings is copied to permanent storage from the original input buffer, so a token remains valid and ! correct even if its source buffer is freed with '_cpp_pop_buffer'. The storage holding the spellings of such tokens remains until the client program calls cpp_destroy, probably at the end of the translation unit. *************** to cpplib itself internally. *** 288,296 **** token stream.

The stand-alone preprocessor can use this flag to decide whether to ! insert a space between tokens in the output. Now consider the result of the following macro expansion: *************** decide whether to insert a space between *** 640,679 **** sum = add (1,2, 3); ==> sum = 1 + 2 +3; ! The interesting thing here is that the tokens `1' and `2' are output ! with a preceding space, and `3' is output without a preceding space, ! but when lexed none of these tokens had that property. Careful ! consideration reveals that `1' gets its preceding whitespace from the ! space preceding `add' in the macro invocation, _not_ replacement list. ! `2' gets its whitespace from the space preceding the parameter `y' in ! the macro replacement list, and `3' has no preceding space because ! parameter `z' has none in the replacement list. Once lexed, tokens are effectively fixed and cannot be altered, since pointers to them might be held in many places, in particular by in-progress macro expansions. So instead of modifying the two tokens ! above, the preprocessor inserts a special token, which I call a ! "padding token", into the token stream to indicate that spacing of the ! subsequent token is special. The preprocessor inserts padding tokens ! in front of every macro expansion and expanded macro argument. These ! point to a "source token" from which the subsequent real token should ! inherit its spacing. In the above example, the source tokens are `add' ! in the macro invocation, and `y' and `z' in the macro replacement list, ! respectively. ! It is quite easy to get multiple padding tokens in a row, for ! example if a macro's first replacement token expands straight into ! another macro. #define foo bar #define bar baz [foo] ==> [baz] ! Here, two padding tokens are generated with sources the `foo' token ! between the brackets, and the `bar' token from foo's replacement list, ! respectively. Clearly the first padding token is the one to use, so ! the output code should contain a rule that the first padding token in a sequence is the one that matters. But what if a macro expansion is left? Adjusting the above example --- 639,677 ---- sum = add (1,2, 3); ==> sum = 1 + 2 +3; !

As shown, now there should be a space before `baz' and the semicolon in the output. ! The rules we decided above fail for `baz': we generate three padding ! tokens, one per macro invocation, before the token `baz'.

It is vital that cpplib get spacing correct in these examples since any of these macro expansions could be stringified, where spacing --- 683,695 ---- [foo] EMPTY; ==> [ baz] ; !

It also inserts appropriate padding tokens on either ! side of tokens created by the `#' and `##' operators. I expanded the ! rule so that, if we see a padding token with a `NULL' source token, _and_ that source token has no leading space, then we behave as if we have seen no padding tokens at all. A quick check shows this rule will then get the above example correct as well. --- 697,707 ---- So, this demonstrates that not just entering macro and argument expansions, but leaving them requires special handling too.

In C mode, this is equivalent to `-std=c90'. In C++ mode, it is ! equivalent to `-std=c++98'. This turns off certain features of GCC that are incompatible with ! ISO C90 (when compiling C code), or of standard C++ (when ! compiling C++ code), such as the `asm' and `typeof' keywords, and ! predefined macros such as `unix' and `vax' that identify the type ! of system you are using. It also enables the undesirable and ! rarely used ISO trigraph feature. For the C compiler, it disables ! recognition of C++ style `//' comments as well as the `inline' ! keyword. ! The alternate keywords `__asm__', `__extension__', `__inline__' ! and `__typeof__' continue to work despite `-ansi'. You would not ! want to use them in an ISO C program, of course, but it is useful ! to put them in header files that might be included in compilations ! done with `-ansi'. Alternate predefined macros such as `__unix__' ! and `__vax__' are also available, with or without `-ansi'. ! The `-ansi' option does not cause non-ISO programs to be rejected ! gratuitously. For that, `-Wpedantic' is required in addition to ! `-ansi'. *Note Warning Options::. ! The macro `__STRICT_ANSI__' is predefined when the `-ansi' option is used. Some header files may notice this macro and refrain from ! declaring certain functions or defining certain macros that the ! ISO standard doesn't call for; this is to avoid interfering with ! any programs that might use these names for other things. Functions that are normally built in but do not have semantics ! defined by ISO C (such as `alloca' and `ffs') are not built-in ! functions when `-ansi' is used. *Note Other built-in functions provided by GCC: Other Builtins, for details of the functions affected. ! `-std=' ! Determine the language standard. *Note Language Standards Supported by GCC: Standards, for details of these standard ! versions. This option is currently only supported when compiling ! C or C++. ! The compiler can accept several base standards, such as `c90' or ! `c++98', and GNU dialects of those standards, such as `gnu90' or ! `gnu++98'. When a base standard is specified, the compiler ! accepts all programs following that standard plus those using GNU ! extensions that do not contradict it. For example, `-std=c90' turns off certain features of GCC that are incompatible with ISO ! C90, such as the `asm' and `typeof' keywords, but not other GNU extensions that do not have a meaning in ISO C90, such as omitting ! the middle term of a `?:' expression. On the other hand, when a GNU dialect of a standard is specified, all features supported by the compiler are enabled, even when those features change the meaning of the base standard. As a result, some strict-conforming programs may be rejected. The particular standard is used by ! `-Wpedantic' to identify which features are GNU extensions given ! that version of the standard.

In C mode, this is equivalent to '-std=c90'. In C++ mode, it is ! equivalent to '-std=c++98'. This turns off certain features of GCC that are incompatible with ! ISO C90 (when compiling C code), or of standard C++ (when compiling ! C++ code), such as the 'asm' and 'typeof' keywords, and predefined ! macros such as 'unix' and 'vax' that identify the type of system ! you are using. It also enables the undesirable and rarely used ISO ! trigraph feature. For the C compiler, it disables recognition of ! C++ style '//' comments as well as the 'inline' keyword. ! The alternate keywords '__asm__', '__extension__', '__inline__' and ! '__typeof__' continue to work despite '-ansi'. You would not want ! to use them in an ISO C program, of course, but it is useful to put ! them in header files that might be included in compilations done ! with '-ansi'. Alternate predefined macros such as '__unix__' and ! '__vax__' are also available, with or without '-ansi'. ! The '-ansi' option does not cause non-ISO programs to be rejected ! gratuitously. For that, '-Wpedantic' is required in addition to ! '-ansi'. *Note Warning Options::. ! The macro '__STRICT_ANSI__' is predefined when the '-ansi' option is used.

This option is currently only supported when compiling C ! or C++. ! The compiler can accept several base standards, such as 'c90' or !

When a base standard is specified, the compiler accepts ! all programs following that standard plus those using GNU ! extensions that do not contradict it. For example, '-std=c90' turns off certain features of GCC that are incompatible with ISO ! C90, such as the 'asm' and 'typeof' keywords, but not other GNU extensions that do not have a meaning in ISO C90, such as omitting ! the middle term of a '?:' expression. On the other hand, when a GNU dialect of a standard is specified, all features supported by the compiler are enabled, even when those features change the meaning of the base standard. As a result, some strict-conforming programs may be rejected. The particular standard is used by ! '-Wpedantic' to identify which features are GNU extensions given ! that version of the standard.

GNU dialects: '-std=c++98', '-std=gnu++98', '-std=gnu++11', ! '-std=gnu++1y'. This option is off by default for ISO C++11 ! onwards ('-std=c++11', ...). ! The following '-W...' options are not affected by '-Wall'. ! '-Weffc++ (C++ and Objective-C++ only)' Warn about violations of the following style guidelines from Scott ! Meyers' 'Effective C++, Second Edition' book: ! * Item 11: Define a copy constructor and an assignment operator ! for classes with dynamically-allocated memory. ! * Item 12: Prefer initialization to assignment in constructors. ! * Item 14: Make destructors virtual in base classes. ! * Item 15: Have 'operator=' return a reference to '*this'. + * Item 23: Don't try to return a reference when you must return + an object. Also warn about violations of the following style guidelines from ! Scott Meyers' 'More Effective C++' book: ! * Item 6: Distinguish between prefix and postfix forms of increment and decrement operators. ! * Item 7: Never overload '&&', '||', or ','. When selecting this option, be aware that the standard library ! headers do not obey all of these guidelines; use 'grep -v' to filter out those warnings. ! '-Wstrict-null-sentinel (C++ and Objective-C++ only)' ! Warn about the use of an uncasted 'NULL' as sentinel. When ! compiling only with GCC this is a valid sentinel, as 'NULL' is ! defined to '__null'. Although it is a null pointer constant rather ! than a null pointer, it is guaranteed to be of the same size as a ! pointer. But this use is not portable across different compilers. ! '-Wno-non-template-friend (C++ and Objective-C++ only)' Disable warnings when non-templatized friend functions are declared within a template. Since the advent of explicit template specification support in G++, if the name of the friend is an ! unqualified-id (i.e., 'friend foo(int)'), the C++ language specification demands that the friend declare or define an ordinary, nontemplate function. (Section 14.5.3). Before G++ implemented explicit specification, unqualified-ids could be interpreted as a particular specialization of a templatized function. Because this non-conforming behavior is no longer the ! default behavior for G++, '-Wnon-template-friend' allows the compiler to check existing code for potential trouble spots and is on by default. This new compiler behavior can be turned off with ! '-Wno-non-template-friend', which keeps the conformant compiler code but disables the helpful warning. ! '-Wold-style-cast (C++ and Objective-C++ only)' Warn if an old-style (C-style) cast to a non-void type is used ! within a C++ program. The new-style casts ('dynamic_cast', ! 'static_cast', 'reinterpret_cast', and 'const_cast') are less vulnerable to unintended effects and much easier to search for. ! '-Woverloaded-virtual (C++ and Objective-C++ only)' Warn when a function declaration hides virtual functions from a base class. For example, in: *************** have meanings only for C++ programs: *** 2746,2763 **** void f(int); }; ! the `A' class version of `f' is hidden in `B', and code like: B* b; b->f(); fails to compile. ! `-Wno-pmf-conversions (C++ and Objective-C++ only)' Disable the diagnostic for converting a bound pointer to member function to a plain pointer. ! `-Wsign-promo (C++ and Objective-C++ only)' Warn when overload resolution chooses a promotion from unsigned or enumerated type to a signed type, over a conversion to an unsigned type of the same size. Previous versions of G++ tried to preserve --- 2729,2746 ---- void f(int); }; ! the 'A' class version of 'f' is hidden in 'B', and code like: B* b; b->f(); fails to compile. ! '-Wno-pmf-conversions (C++ and Objective-C++ only)' Disable the diagnostic for converting a bound pointer to member function to a plain pointer. ! '-Wsign-promo (C++ and Objective-C++ only)' Warn when overload resolution chooses a promotion from unsigned or enumerated type to a signed type, over a conversion to an unsigned type of the same size. Previous versions of G++ tried to preserve *************** languages themselves. *Note Language St *** 2774,2975 **** Standards, for references.) This section describes the command-line options that are only ! meaningful for Objective-C and Objective-C++ programs. You can also ! use most of the language-independent GNU compiler options. For ! example, you might compile a file `some_class.m' like this: gcc -g -fgnu-runtime -O -c some_class.m ! In this example, `-fgnu-runtime' is an option meant only for ! Objective-C and Objective-C++ programs; you can use the other options ! with any language supported by GCC. Note that since Objective-C is an extension of the C language, Objective-C compilations may also use options specific to the C ! front-end (e.g., `-Wtraditional'). Similarly, Objective-C++ ! compilations may use C++-specific options (e.g., `-Wabi'). ! Here is a list of options that are _only_ for compiling Objective-C ! and Objective-C++ programs: ! `-fconstant-string-class=CLASS-NAME' Use CLASS-NAME as the name of the class to instantiate for each ! literal string specified with the syntax `@"..."'. The default ! class name is `NXConstantString' if the GNU runtime is being used, ! and `NSConstantString' if the NeXT runtime is being used (see ! below). The `-fconstant-cfstrings' option, if also present, ! overrides the `-fconstant-string-class' setting and cause `@"..."' literals to be laid out as constant CoreFoundation strings. ! `-fgnu-runtime' Generate object code compatible with the standard GNU Objective-C runtime. This is the default for most types of systems. ! `-fnext-runtime' Generate output compatible with the NeXT runtime. This is the ! default for NeXT-based systems, including Darwin and Mac OS X. ! The macro `__NEXT_RUNTIME__' is predefined if (and only if) this ! option is used. ! `-fno-nil-receivers' ! Assume that all Objective-C message dispatches (`[receiver message:arg]') in this translation unit ensure that the receiver is ! not `nil'. This allows for more efficient entry points in the runtime to be used. This option is only available in conjunction with the NeXT runtime and ABI version 0 or 1. ! `-fobjc-abi-version=N' Use version N of the Objective-C ABI for the selected runtime. This option is currently supported only for the NeXT runtime. In that case, Version 0 is the traditional (32-bit) ABI without support for properties and other Objective-C 2.0 additions. Version 1 is the traditional (32-bit) ABI with support for properties and other Objective-C 2.0 additions. Version 2 is the ! modern (64-bit) ABI. If nothing is specified, the default is ! Version 0 on 32-bit target machines, and Version 2 on 64-bit ! target machines. ! `-fobjc-call-cxx-cdtors' For each Objective-C class, check if any of its instance variables is a C++ object with a non-trivial default constructor. If so, ! synthesize a special `- (id) .cxx_construct' instance method which runs non-trivial default constructors on any such instance ! variables, in order, and then return `self'. Similarly, check if any instance variable is a C++ object with a non-trivial ! destructor, and if so, synthesize a special `- (void) .cxx_destruct' method which runs all such default destructors, in reverse order. ! The `- (id) .cxx_construct' and `- (void) .cxx_destruct' methods ! thusly generated only operate on instance variables declared in ! the current Objective-C class, and not those inherited from superclasses. It is the responsibility of the Objective-C runtime to invoke all such methods in an object's inheritance hierarchy. ! The `- (id) .cxx_construct' methods are invoked by the runtime ! immediately after a new object instance is allocated; the `- ! (void) .cxx_destruct' methods are invoked immediately before the ! runtime deallocates an object instance. As of this writing, only the NeXT runtime on Mac OS X 10.4 and ! later has support for invoking the `- (id) .cxx_construct' and `- (void) .cxx_destruct' methods. ! `-fobjc-direct-dispatch' Allow fast jumps to the message dispatcher. On Darwin this is accomplished via the comm page. ! `-fobjc-exceptions' Enable syntactic support for structured exception handling in Objective-C, similar to what is offered by C++ and Java. This ! option is required to use the Objective-C keywords `@try', ! `@throw', `@catch', `@finally' and `@synchronized'. This option ! is available with both the GNU runtime and the NeXT runtime (but ! not available in conjunction with the NeXT runtime on Mac OS X ! 10.2 and earlier). ! `-fobjc-gc' Enable garbage collection (GC) in Objective-C and Objective-C++ programs. This option is only available with the NeXT runtime; the GNU runtime has a different garbage collection implementation that does not require special compiler flags. ! `-fobjc-nilcheck' For the NeXT runtime with version 2 of the ABI, check for a nil receiver in method invocations before doing the actual method call. ! This is the default and can be disabled using ! `-fno-objc-nilcheck'. Class methods and super calls are never ! checked for nil in this way no matter what this flag is set to. ! Currently this flag does nothing when the GNU runtime, or an older ! version of the NeXT runtime ABI, is used. ! `-fobjc-std=objc1' Conform to the language syntax of Objective-C 1.0, the language ! recognized by GCC 4.0. This only affects the Objective-C ! additions to the C/C++ language; it does not affect conformance to ! C/C++ standards, which is controlled by the separate C/C++ dialect ! option flags. When this option is used with the Objective-C or Objective-C++ compiler, any Objective-C syntax that is not recognized by GCC 4.0 is rejected. This is useful if you need to make sure that your Objective-C code can be compiled with older versions of GCC. ! `-freplace-objc-classes' ! Emit a special marker instructing `ld(1)' not to statically link in ! the resulting object file, and allow `dyld(1)' to load it in at ! run time instead. This is used in conjunction with the Fix-and-Continue debugging mode, where the object file in question ! may be recompiled and dynamically reloaded in the course of ! program execution, without the need to restart the program itself. Currently, Fix-and-Continue functionality is only available in conjunction with the NeXT runtime on Mac OS X 10.3 and later. ! `-fzero-link' When compiling for the NeXT runtime, the compiler ordinarily ! replaces calls to `objc_getClass("...")' (when the name of the class is known at compile time) with static class references that get initialized at load time, which improves run-time performance. ! Specifying the `-fzero-link' flag suppresses this behavior and ! causes calls to `objc_getClass("...")' to be retained. This is useful in Zero-Link debugging mode, since it allows for individual ! class implementations to be modified during program execution. ! The GNU runtime currently always retains calls to ! `objc_get_class("...")' regardless of command-line options. ! `-gen-decls' ! Dump interface declarations for all classes seen in the source ! file to a file named `SOURCENAME.decl'. ! `-Wassign-intercept (Objective-C and Objective-C++ only)' Warn whenever an Objective-C assignment is being intercepted by the garbage collector. ! `-Wno-protocol (Objective-C and Objective-C++ only)' ! If a class is declared to implement a protocol, a warning is ! issued for every method in the protocol that is not implemented by ! the class. The default behavior is to issue a warning for every ! method not explicitly implemented in the class, even if a method implementation is inherited from the superclass. If you use the ! `-Wno-protocol' option, then methods inherited from the superclass are considered to be implemented, and no warning is issued for them. ! `-Wselector (Objective-C and Objective-C++ only)' Warn if multiple methods of different types for the same selector are found during compilation. The check is performed on the list of methods in the final stage of compilation. Additionally, a check is performed for each selector appearing in a ! `@selector(...)' expression, and a corresponding method for that selector has been found during compilation. Because these checks scan the method table only at the end of compilation, these warnings are not produced if the final stage of compilation is not reached, for example because an error is found during compilation, ! or because the `-fsyntax-only' option is being used. ! `-Wstrict-selector-match (Objective-C and Objective-C++ only)' Warn if multiple methods with differing argument and/or return types are found for a given selector when attempting to send a ! message using this selector to a receiver of type `id' or `Class'. ! When this flag is off (which is the default behavior), the ! compiler omits such warnings if any differences found are confined ! to types that share the same size and alignment. ! `-Wundeclared-selector (Objective-C and Objective-C++ only)' ! Warn if a `@selector(...)' expression referring to an undeclared selector is found. A selector is considered undeclared if no ! method with that name has been declared before the ! `@selector(...)' expression, either explicitly in an `@interface' ! or `@protocol' declaration, or implicitly in an `@implementation' ! section. This option always performs its checks as soon as a ! `@selector(...)' expression is found, while `-Wselector' only ! performs its checks in the final stage of compilation. This also ! enforces the coding style convention that methods and selectors ! must be declared before being used. ! `-print-objc-runtime-info' Generate C header describing the largest structure that is passed by value, if any. -  File: gcc.info, Node: Language Independent Options, Next: Warning Options, Prev: Objective-C and Objective-C++ Dialect Options, Up: Invoking GCC --- 2757,2957 ---- Standards, for references.)

The specifier for a ! warning is appended; for example `-Werror=switch' turns the ! warnings controlled by `-Wswitch' into errors. This switch takes a ! negative form, to be used to negate `-Werror' for specific ! warnings; for example `-Wno-error=switch' makes `-Wswitch' ! warnings not be errors, even when `-Werror' is in effect.

However, ! without this option, certain GNU extensions and traditional C and ! C++ features are supported as well. With this option, they are rejected. ! `-Wpedantic' does not cause warning messages for use of the ! alternate keywords whose names begin and end with `__'. Pedantic warnings are also disabled in the expression that follows ! `__extension__'. However, only system header files should use ! these escape routes; application programs should avoid them. ! *Note Alternate Keywords::. ! Some users try to use `-Wpedantic' to check programs for strict ISO C conformance.

A feature to report any failure to conform to ISO C might be ! useful in some instances, but would require considerable ! additional work and would be quite different from `-Wpedantic'. ! We don't have plans to support such a feature in the near future. !

If N is 0 (the default), there is no limit on the ! number of error messages produced. If '-Wfatal-errors' is also ! specified, then '-Wfatal-errors' takes precedence over this option. ! '-w' Inhibit all warning messages. ! '-Werror' Make all warnings into errors. ! '-Werror=' Make the specified warning into an error. The specifier for a ! warning is appended; for example '-Werror=switch' turns the ! warnings controlled by '-Wswitch' into errors. This switch takes a ! negative form, to be used to negate '-Werror' for specific ! warnings; for example '-Wno-error=switch' makes '-Wswitch' warnings ! not be errors, even when '-Werror' is in effect. The warning message for each controllable warning includes the option that controls the warning. That option can then be used ! with '-Werror=' and '-Wno-error=' as described above. (Printing of ! the option in the warning message can be disabled using the ! '-fno-diagnostics-show-option' flag.) ! Note that specifying '-Werror='FOO automatically implies '-W'FOO. ! However, '-Wno-error='FOO does not imply anything. ! '-Wfatal-errors' This option causes the compiler to abort compilation on the first error occurred rather than trying to keep going and printing further error messages. You can request many specific warnings with options beginning with ! '-W', for example '-Wimplicit' to request warnings on implicit declarations. Each of these specific warning options also has a ! negative form beginning '-Wno-' to turn off warnings; for example, ! '-Wno-implicit'. This manual lists only one of the two forms, whichever ! is not the default. For further language-specific options also refer to ! *note C++ Dialect Options:: and *note Objective-C and Objective-C++ ! Dialect Options::. When an unrecognized warning option is requested (e.g., ! '-Wunknown-warning'), GCC emits a diagnostic stating that the option is ! not recognized. However, if the '-Wno-' form is used, the behavior is ! slightly different: no diagnostic is produced for '-Wno-unknown-warning' ! unless other diagnostics are being produced. This allows the use of new ! '-Wno-' options with old compilers, but if something goes wrong, the ! compiler warns that an unrecognized option is present. ! '-Wpedantic' ! '-pedantic' ! Issue all the warnings demanded by strict ISO C and ISO C++; reject ! all programs that use forbidden extensions, and some other programs ! that do not follow ISO C and ISO C++. For ISO C, follows the ! version of the ISO C standard specified by any '-std' option used. Valid ISO C and ISO C++ programs should compile properly with or ! without this option (though a rare few require '-ansi' or a '-std' ! option specifying the required version of ISO C). However, without ! this option, certain GNU extensions and traditional C and C++ ! features are supported as well. With this option, they are rejected. ! '-Wpedantic' does not cause warning messages for use of the ! alternate keywords whose names begin and end with '__'. Pedantic warnings are also disabled in the expression that follows ! '__extension__'. However, only system header files should use ! these escape routes; application programs should avoid them. *Note ! Alternate Keywords::. ! Some users try to use '-Wpedantic' to check programs for strict ISO C conformance. They soon find that it does not do quite what they want: it finds some non-ISO practices, but not all--only those for which ISO C _requires_ a diagnostic, and some others for which diagnostics have been added. ! A feature to report any failure to conform to ISO C might be useful ! in some instances, but would require considerable additional work ! and would be quite different from '-Wpedantic'. We don't have ! plans to support such a feature in the near future. ! Where the standard specified with '-std' represents a GNU extended ! dialect of C, such as 'gnu90' or 'gnu99', there is a corresponding "base standard", the version of ISO C on which the GNU extended ! dialect is based. Warnings from '-Wpedantic' are given where they are required by the base standard. (It does not make sense for such warnings to be given only for features not in the specified GNU C dialect, since by definition the GNU dialects of C include ! all features the compiler supports with the given option, and there ! would be nothing to warn about.) ! '-pedantic-errors' ! Like '-Wpedantic', except that errors are produced rather than warnings. !

Where the unused arguments lie between used arguments that are ! specified with `$' operand number specifications, normally warnings are still given, since the implementation could not ! know what type to pass to `va_arg' to skip the unused ! arguments. However, in the case of `scanf' formats, this option suppresses the warning if the unused arguments are all pointers, since the Single Unix Specification says that such unused arguments are allowed. ! `-Wno-format-zero-length' !

ISO C ! prohibits qualified `void' return types on function definitions, ! so such return types always receive a warning even without this option. ! This warning is also enabled by `-Wextra'. ! `-Wmain' ! Warn if the type of `main' is suspicious. `main' should be a function with external linkage, returning int, taking either zero arguments, two, or three arguments of appropriate types.

However, sometimes when characters outside the basic ASCII character set are used, you can have two different character sequences that look the same. To avoid confusion, the ISO 10646 standard sets out some "normalization rules" which when applied ensure that two sequences ! that look the same are turned into the same sequence. GCC can ! warn you if you are using identifiers that have not been ! normalized; this option controls that warning. There are four levels of warning supported by GCC. The default is ! `-Wnormalized=nfc', which warns about any identifier that is not ! in the ISO 10646 "C" normalized form, "NFC". NFC is the ! recommended form for most uses. Unfortunately, there are some characters allowed in identifiers by ISO C and ISO C++ that, when turned into NFC, are not allowed in identifiers. That is, there's no way to use these symbols in portable ISO C or C++ and have all your identifiers in NFC. ! `-Wnormalized=id' suppresses the warning for these characters. It is hoped that future versions of the standards involved will correct this, which is why this option is not the default. You can switch the warning off for all characters by writing ! `-Wnormalized=none'. You should only do this if you are using ! some other normalization scheme (like "D"), because otherwise you ! can easily create bugs that are literally impossible to see. Some characters in ISO 10646 have distinct meanings but look identical in some fonts or display methodologies, especially once ! formatting has been applied. For instance `\u207F', "SUPERSCRIPT ! LATIN SMALL LETTER N", displays just like a regular `n' that has been placed in a superscript. ISO 10646 defines the "NFKC" normalization scheme to convert all these into a standard form as well, and GCC warns if your code is not in NFKC if you use ! `-Wnormalized=nfkc'. This warning is comparable to warning about every identifier that contains the letter O because it might be confused with the digit 0, and so is not the default, but may be useful as a local coding convention if the programming environment cannot be fixed to display these characters distinctly. ! `-Wno-deprecated' Do not warn about usage of deprecated features. *Note Deprecated Features::. ! `-Wno-deprecated-declarations' Do not warn about uses of functions (*note Function Attributes::), variables (*note Variable Attributes::), and types (*note Type !

For ! instance, in this code, the variable `f.x' in `struct bar' is ! misaligned even though `struct bar' does not itself have the ! packed attribute: struct foo { int x; --- 4255,4340 ---- struct s { int f, g, h; }; struct s x = { .f = 3, .g = 4 }; ! This warning is included in '-Wextra'. To get other '-Wextra' ! warnings without this one, use '-Wextra -Wno-missing-field-initializers'. ! '-Wno-multichar' ! Do not warn if a multicharacter constant (''FOOF'') is used. Usually they indicate a typo in the user's code, as they have implementation-defined values, and should not be used in portable code. ! '-Wnormalized=' In ISO C and ISO C++, two identifiers are different if they are different sequences of characters. However, sometimes when characters outside the basic ASCII character set are used, you can have two different character sequences that look the same. To avoid confusion, the ISO 10646 standard sets out some "normalization rules" which when applied ensure that two sequences ! that look the same are turned into the same sequence. GCC can warn ! you if you are using identifiers that have not been normalized; ! this option controls that warning. There are four levels of warning supported by GCC. The default is ! '-Wnormalized=nfc', which warns about any identifier that is not in ! the ISO 10646 "C" normalized form, "NFC". NFC is the recommended ! form for most uses. Unfortunately, there are some characters allowed in identifiers by ISO C and ISO C++ that, when turned into NFC, are not allowed in identifiers. That is, there's no way to use these symbols in portable ISO C or C++ and have all your identifiers in NFC. ! '-Wnormalized=id' suppresses the warning for these characters. It is hoped that future versions of the standards involved will correct this, which is why this option is not the default. You can switch the warning off for all characters by writing ! '-Wnormalized=none'. You should only do this if you are using some ! other normalization scheme (like "D"), because otherwise you can ! easily create bugs that are literally impossible to see. Some characters in ISO 10646 have distinct meanings but look identical in some fonts or display methodologies, especially once ! formatting has been applied. For instance '\u207F', "SUPERSCRIPT ! LATIN SMALL LETTER N", displays just like a regular 'n' that has been placed in a superscript. ISO 10646 defines the "NFKC" normalization scheme to convert all these into a standard form as well, and GCC warns if your code is not in NFKC if you use ! '-Wnormalized=nfkc'. This warning is comparable to warning about every identifier that contains the letter O because it might be confused with the digit 0, and so is not the default, but may be useful as a local coding convention if the programming environment cannot be fixed to display these characters distinctly. !

To verify full coverage during '-fcompare-debug' testing, set !

The intent is to reduce duplicate struct debug information between different object files within the same program. ! This option is a detailed version of `-femit-struct-debug-reduced' ! and `-femit-struct-debug-baseonly', which serves for most needs. A specification has the syntax ! [`dir:'|`ind:'][`ord:'|`gen:'](`any'|`sys'|`base'|`none') The optional first word limits the specification to structs that ! are used directly (`dir:') or used indirectly (`ind:'). A struct type is used directly when it is the type of a variable, member. ! Indirect uses arise through pointers to structs. That is, when ! use of an incomplete struct is valid, the use is indirect. An ! example is `struct one direct; struct two * indirect;'. The optional second word limits the specification to ordinary ! structs (`ord:') or generic structs (`gen:'). Generic structs are a bit complicated to explain. For C++, these are non-explicit ! specializations of template classes, or non-template classes ! within the above. Other programming languages have generics, but ! `-femit-struct-debug-detailed' does not yet implement them. The third word specifies the source files for those structs for which the compiler should emit debug information. The values ! `none' and `any' have the normal meaning. The value `base' means that the base of name of the file in which the type declaration appears must match the base of the name of the main compilation ! file. In practice, this means that when compiling `foo.c', debug information is generated for types declared in that file and ! `foo.h', but not other header files. The value `sys' means those ! types satisfying `base' or declared in system or compiler headers. You may need to experiment to determine the best settings for your application. ! The default is `-femit-struct-debug-detailed=all'. This option works only with DWARF 2. ! `-fno-merge-debug-strings' Direct the linker to not merge together strings in the debugging information that are identical in different object files. Merging is not supported by all assemblers or linkers. Merging decreases ! the size of the debug information in the output file at the cost ! of increasing link processing time.

AUXNAME is generated from the ! name of the output file, if explicitly specified and it is not an executable, otherwise it is the basename of the source file. An entry is made up of three fields: * The name of the function. - * A number of bytes. ! * One or more qualifiers: `static', `dynamic', `bounded'. ! ! The qualifier `static' means that the function manipulates the stack statically: a fixed number of bytes are allocated for the frame on function entry and released on function exit; no stack adjustments are otherwise made in the function. The second field is this fixed number of bytes. ! The qualifier `dynamic' means that the function manipulates the stack dynamically: in addition to the static allocation described above, stack adjustments are made in the body of the function, for example to push/pop arguments around function calls. If the ! qualifier `bounded' is also present, the amount of these adjustments is bounded at compile time and the second field is an upper bound of the total amount of stack used by the function. If it is not present, the amount of these adjustments is not bounded at compile time and the second field only represents the bounded part. ! `-fprofile-arcs' Add code so that program flow "arcs" are instrumented. During execution the program records how many times each branch and call is executed and how many times it is taken or returns. When the compiled program exits it saves this data to a file called ! `AUXNAME.gcda' for each source file. The data may be used for ! profile-directed optimizations (`-fbranch-probabilities'), or for ! test coverage analysis (`-ftest-coverage').

Refer to the `gcov' documentation for further information. ! ! With `-fprofile-arcs', for each function of your program GCC creates a program flow graph, then finds a spanning tree for the graph. Only arcs that are not on the spanning tree have to be instrumented: the compiler adds code to count the number of times ! that these arcs are executed. When an arc is the only exit or ! only entrance to a block, the instrumentation code can be added to ! the block; otherwise, a new basic block must be created to hold ! the instrumentation code. ! `-ftest-coverage' ! Produce a notes file that the `gcov' code-coverage utility (*note ! `gcov'--a Test Coverage Program: Gcov.) can use to show program ! coverage.

Coverage data matches the source files more closely if you do not optimize. ! `-fdbg-cnt-list' Print the name and the counter upper bound for all debug counters. ! `-fdbg-cnt=COUNTER-VALUE-LIST' Set the internal debug counter upper bound. COUNTER-VALUE-LIST is a comma-separated list of NAME:VALUE pairs which sets the upper ! bound of each debug counter NAME to VALUE. All debug counters ! have the initial upper bound of `UINT_MAX'; thus `dbg_cnt()' ! returns true always unless the upper bound is set by this option. !

Enable all the available tree dumps with the flags provided ! in this option. ! `-fopt-info' ! `-fopt-info-OPTIONS' ! `-fopt-info-OPTIONS=FILENAME' ! Controls optimization dumps from various optimization passes. If ! the `-OPTIONS' form is used, OPTIONS is a list of `-' separated options to select the dump details and optimizations. If OPTIONS ! is not specified, it defaults to `all' for details and `optall' ! for optimization groups. If the FILENAME is not specified, it ! defaults to `stderr'. Note that the output FILENAME will be ! overwritten in case of multiple translation units. If a combined ! output from multiple translation units is desired, `stderr' should ! be used instead. The options can be divided into two groups, 1) options describing the verbosity of the dump, and 2) options describing which ! optimizations should be included. The options from both the groups ! can be freely mixed as they are non-overlapping. However, in case of any conflicts, the latter options override the earlier options ! on the command line. Though multiple -fopt-info options are ! accepted, only one of them can have `=filename'. If other filenames are provided then all but the first one are ignored. The dump verbosity has the following options ! `optimized' Print information when an optimization is successfully ! applied. It is up to a pass to decide which information is ! relevant. For example, the vectorizer passes print the source location of loops which got successfully vectorized. ! ! `missed' ! Print information about missed optimizations. Individual passes control which information to include in the output. For example, gcc -O2 -ftree-vectorize -fopt-info-vec-missed ! will print information about missed optimization ! opportunities from vectorization passes on stderr. ! ! `note' Print verbose information about optimizations, such as certain transformations, more detailed messages about decisions etc. ! ! `all' ! Print detailed optimization information. This includes OPTIMIZED, MISSED, and NOTE. The second set of options describes a group of optimizations and may include one or more of the following. ! `ipa' Enable dumps from all interprocedural optimizations. ! ! `loop' Enable dumps from all loop optimizations. ! ! `inline' Enable dumps from all inlining optimizations. ! ! `vec' Enable dumps from all vectorization optimizations. For example, gcc -O3 -fopt-info-missed=missed.all outputs missed optimization report from all the passes into ! `missed.all'. As another example, gcc -O3 -fopt-info-inline-optimized-missed=inline.txt will output information about missed optimizations as well as ! optimized locations from all the inlining passes into `inline.txt'. ! If the FILENAME is provided, then the dumps from all the ! applicable optimizations are concatenated into the `filename'. ! Otherwise the dump is output onto `stderr'. If OPTIONS is omitted, ! it defaults to `all-optall', which means dump all available ! optimization info from all the passes. In the following example, ! all optimization info is output on to `stderr'. gcc -O3 -fopt-info ! Note that `-fopt-info-vec-missed' behaves the same as ! `-fopt-info-missed-vec'. As another example, consider gcc -fopt-info-vec-missed=vec.miss -fopt-info-loop-optimized=loop.opt ! Here the two output filenames `vec.miss' and `loop.opt' are in ! conflict since only one output file is allowed. In this case, only the first option takes effect and the subsequent options are ! ignored. Thus only the `vec.miss' is produced which cotaints dumps from the vectorizer about missed opportunities. ! `-ftree-vectorizer-verbose=N' This option is deprecated and is implemented in terms of ! `-fopt-info'. Please use `-fopt-info-KIND' form instead, where ! KIND is one of the valid opt-info options. It prints additional optimization information. For N=0 no diagnostic information is reported. If N=1 the vectorizer reports each loop that got vectorized, and the total number of loops that got vectorized. If N=2 the vectorizer reports locations which could not be vectorized ! and the reasons for those. For any higher verbosity levels all the analysis and transformation information from the vectorizer is reported. ! Note that the information output by `-ftree-vectorizer-verbose' ! option is sent to `stderr'. If the equivalent form ! `-fopt-info-OPTIONS=FILENAME' is used then the output is sent into FILENAME instead. ! `-frandom-seed=STRING' This option provides a seed that GCC uses in place of random numbers in generating certain symbol names that have to be different in every compiled file. It is also used to place unique stamps in coverage data files and the object files that produce ! them. You can use the `-frandom-seed' option to produce reproducibly identical object files. The STRING should be different for every file you compile. ! `-fsched-verbose=N' On targets that use instruction scheduling, this option controls the amount of debugging output the scheduler prints. This information is written to standard error, unless ! `-fdump-rtl-sched1' or `-fdump-rtl-sched2' is specified, in which ! case it is output to the usual dump listing file, `.sched1' or ! `.sched2' respectively. However for N greater than nine, the output is always printed to standard error. ! For N greater than zero, `-fsched-verbose' outputs the same ! information as `-fdump-rtl-sched1' and `-fdump-rtl-sched2'. For N greater than one, it also output basic block probabilities, detailed ready list information and unit/insn info. For N greater than two, it includes RTL at abort point, control-flow and regions ! info. And for N over four, `-fsched-verbose' also includes dependence info. ! `-save-temps' ! `-save-temps=cwd' Store the usual "temporary" intermediate files permanently; place them in the current directory and name them based on the source ! file. Thus, compiling `foo.c' with `-c -save-temps' produces files ! `foo.i' and `foo.s', as well as `foo.o'. This creates a ! preprocessed `foo.i' output file even though the compiler now normally uses an integrated preprocessor. ! When used in combination with the `-x' command-line option, ! `-save-temps' is sensible enough to avoid over writing an input source file with the same extension as an intermediate file. The corresponding intermediate file may be obtained by renaming the ! source file before using `-save-temps'. If you invoke GCC in parallel, compiling several different source files that share a common base name in different subdirectories or the same source file compiled for multiple output destinations, it ! is likely that the different parallel compilers will interfere ! with each other, and overwrite the temporary files. For instance: gcc -save-temps -o outdir1/foo.o indir1/foo.c& gcc -save-temps -o outdir2/foo.o indir2/foo.c& ! may result in `foo.i' and `foo.o' being written to simultaneously by both compilers. ! `-save-temps=obj' Store the usual "temporary" intermediate files permanently. If the ! `-o' option is used, the temporary files are based on the object ! file. If the `-o' option is not used, the `-save-temps=obj' ! switch behaves like `-save-temps'. For example: --- 5386,5740 ---- When dumping RTL, print the RTL in slim (condensed) form instead of the default LISP-like representation. ! 'raw' Print a raw representation of the tree. By default, trees are pretty-printed into a C-like representation. ! 'details' ! Enable more detailed dumps (not honored by every dump option). ! Also include information from the optimization passes. ! 'stats' Enable dumping various statistics about the pass (not honored by every dump option). ! 'blocks' Enable showing basic block boundaries (disabled in raw dumps). ! 'graph' For each of the other indicated dump files ! ('-fdump-rtl-PASS'), dump a representation of the control flow ! graph suitable for viewing with GraphViz to ! 'FILE.PASSID.PASS.dot'. Each function in the file is pretty-printed as a subgraph, so that GraphViz can render them all in a single plot. ! This option currently only works for RTL dumps, and the RTL is ! always dumped in slim form. ! 'vops' Enable showing virtual operands for every statement. ! 'lineno' Enable showing line numbers for statements. ! 'uid' ! Enable showing the unique ID ('DECL_UID') for each variable. ! 'verbose' Enable showing the tree dump for each statement. ! 'eh' Enable showing the EH region number holding each statement. ! 'scev' Enable showing scalar evolution analysis details. ! 'optimized' Enable showing optimization information (only available in certain passes). ! 'missed' ! Enable showing missed optimization information (only available ! in certain passes). ! 'notes' ! Enable other detailed optimization information (only available ! in certain passes). ! '=FILENAME' Instead of an auto named dump file, output into the given file ! name. The file names 'stdout' and 'stderr' are treated specially and are considered already open standard streams. For example, gcc -O2 -ftree-vectorize -fdump-tree-vect-blocks=foo.dump -fdump-tree-pre=stderr file.c ! outputs vectorizer dump into 'foo.dump', while the PRE dump is ! output on to 'stderr'. If two conflicting dump filenames are given for the same pass, then the latter option overrides the earlier one. ! 'all' ! Turn on all options, except 'raw', 'slim', 'verbose' and ! 'lineno'. ! 'optall' ! Turn on all optimization options, i.e., 'optimized', 'missed', ! and 'note'. The following tree dumps are possible: ! 'original' ! Dump before any tree based optimization, to 'FILE.original'. ! 'optimized' ! Dump after all tree based optimization, to 'FILE.optimized'. ! 'gimple' ! Dump each function before and after the gimplification pass to ! a file. The file name is made by appending '.gimple' to the ! source file name. ! ! 'cfg' Dump the control flow graph of each function to a file. The ! file name is made by appending '.cfg' to the source file name. ! 'ch' Dump each function after copying loop headers. The file name ! is made by appending '.ch' to the source file name. ! 'ssa' ! Dump SSA related information to a file. The file name is made ! by appending '.ssa' to the source file name. ! 'alias' ! Dump aliasing information for each function. The file name is ! made by appending '.alias' to the source file name. ! 'ccp' Dump each function after CCP. The file name is made by ! appending '.ccp' to the source file name. ! 'storeccp' Dump each function after STORE-CCP. The file name is made by ! appending '.storeccp' to the source file name. ! 'pre' Dump trees after partial redundancy elimination. The file ! name is made by appending '.pre' to the source file name. ! 'fre' Dump trees after full redundancy elimination. The file name ! is made by appending '.fre' to the source file name. ! 'copyprop' Dump trees after copy propagation. The file name is made by ! appending '.copyprop' to the source file name. ! 'store_copyprop' Dump trees after store copy-propagation. The file name is ! made by appending '.store_copyprop' to the source file name. ! 'dce' ! Dump each function after dead code elimination. The file name ! is made by appending '.dce' to the source file name. ! 'mudflap' Dump each function after adding mudflap instrumentation. The ! file name is made by appending '.mudflap' to the source file name. ! 'sra' Dump each function after performing scalar replacement of ! aggregates. The file name is made by appending '.sra' to the source file name. ! 'sink' Dump each function after performing code sinking. The file ! name is made by appending '.sink' to the source file name. ! 'dom' Dump each function after applying dominator tree ! optimizations. The file name is made by appending '.dom' to the source file name. ! 'dse' ! Dump each function after applying dead store elimination. The ! file name is made by appending '.dse' to the source file name. ! 'phiopt' Dump each function after optimizing PHI nodes into straightline code. The file name is made by appending ! '.phiopt' to the source file name. ! 'forwprop' Dump each function after forward propagating single use ! variables. The file name is made by appending '.forwprop' to the source file name. ! 'copyrename' Dump each function after applying the copy rename optimization. The file name is made by appending ! '.copyrename' to the source file name. ! 'nrv' Dump each function after applying the named return value optimization on generic trees. The file name is made by ! appending '.nrv' to the source file name. ! 'vect' ! Dump each function after applying vectorization of loops. The ! file name is made by appending '.vect' to the source file name. ! 'slp' Dump each function after applying vectorization of basic ! blocks. The file name is made by appending '.slp' to the source file name. ! 'vrp' ! Dump each function after Value Range Propagation (VRP). The ! file name is made by appending '.vrp' to the source file name. ! 'all' ! Enable all the available tree dumps with the flags provided in ! this option. ! '-fopt-info' ! '-fopt-info-OPTIONS' ! '-fopt-info-OPTIONS=FILENAME' ! Controls optimization dumps from various optimization passes. If ! the '-OPTIONS' form is used, OPTIONS is a list of '-' separated options to select the dump details and optimizations. If OPTIONS ! is not specified, it defaults to 'all' for details and 'optall' for ! optimization groups. If the FILENAME is not specified, it defaults ! to 'stderr'. Note that the output FILENAME will be overwritten in ! case of multiple translation units. If a combined output from ! multiple translation units is desired, 'stderr' should be used ! instead. The options can be divided into two groups, 1) options describing the verbosity of the dump, and 2) options describing which ! optimizations should be included. The options from both the groups ! can be freely mixed as they are non-overlapping. However, in case of any conflicts, the latter options override the earlier options ! on the command line. Though multiple -fopt-info options are ! accepted, only one of them can have '=filename'. If other filenames are provided then all but the first one are ignored. The dump verbosity has the following options ! 'optimized' Print information when an optimization is successfully ! applied. It is up to a pass to decide which information is ! relevant. For example, the vectorizer passes print the source location of loops which got successfully vectorized. ! 'missed' ! Print information about missed optimizations. Individual passes control which information to include in the output. For example, gcc -O2 -ftree-vectorize -fopt-info-vec-missed ! will print information about missed optimization opportunities ! from vectorization passes on stderr. ! 'note' Print verbose information about optimizations, such as certain transformations, more detailed messages about decisions etc. ! 'all' ! Print detailed optimization information. This includes OPTIMIZED, MISSED, and NOTE. The second set of options describes a group of optimizations and may include one or more of the following. ! 'ipa' Enable dumps from all interprocedural optimizations. ! 'loop' Enable dumps from all loop optimizations. ! 'inline' Enable dumps from all inlining optimizations. ! 'vec' Enable dumps from all vectorization optimizations. For example, gcc -O3 -fopt-info-missed=missed.all outputs missed optimization report from all the passes into ! 'missed.all'. As another example, gcc -O3 -fopt-info-inline-optimized-missed=inline.txt will output information about missed optimizations as well as ! optimized locations from all the inlining passes into 'inline.txt'. ! If the FILENAME is provided, then the dumps from all the applicable ! optimizations are concatenated into the 'filename'. Otherwise the ! dump is output onto 'stderr'. If OPTIONS is omitted, it defaults ! to 'all-optall', which means dump all available optimization info ! from all the passes. In the following example, all optimization ! info is output on to 'stderr'. gcc -O3 -fopt-info ! Note that '-fopt-info-vec-missed' behaves the same as ! '-fopt-info-missed-vec'. As another example, consider gcc -fopt-info-vec-missed=vec.miss -fopt-info-loop-optimized=loop.opt ! Here the two output filenames 'vec.miss' and 'loop.opt' are in ! conflict since only one output file is allowed. In this case, only the first option takes effect and the subsequent options are ! ignored. Thus only the 'vec.miss' is produced which cotaints dumps from the vectorizer about missed opportunities. ! '-ftree-vectorizer-verbose=N' This option is deprecated and is implemented in terms of ! '-fopt-info'. Please use '-fopt-info-KIND' form instead, where ! KIND is one of the valid opt-info options. It prints additional optimization information. For N=0 no diagnostic information is reported. If N=1 the vectorizer reports each loop that got vectorized, and the total number of loops that got vectorized. If N=2 the vectorizer reports locations which could not be vectorized ! and the reasons for those. For any higher verbosity levels all the analysis and transformation information from the vectorizer is reported. ! Note that the information output by '-ftree-vectorizer-verbose' ! option is sent to 'stderr'. If the equivalent form ! '-fopt-info-OPTIONS=FILENAME' is used then the output is sent into FILENAME instead. ! '-frandom-seed=STRING' This option provides a seed that GCC uses in place of random numbers in generating certain symbol names that have to be different in every compiled file. It is also used to place unique stamps in coverage data files and the object files that produce ! them. You can use the '-frandom-seed' option to produce reproducibly identical object files. The STRING should be different for every file you compile. ! '-fsched-verbose=N' On targets that use instruction scheduling, this option controls the amount of debugging output the scheduler prints. This information is written to standard error, unless ! '-fdump-rtl-sched1' or '-fdump-rtl-sched2' is specified, in which ! case it is output to the usual dump listing file, '.sched1' or ! '.sched2' respectively. However for N greater than nine, the output is always printed to standard error. ! For N greater than zero, '-fsched-verbose' outputs the same ! information as '-fdump-rtl-sched1' and '-fdump-rtl-sched2'. For N greater than one, it also output basic block probabilities, detailed ready list information and unit/insn info. For N greater than two, it includes RTL at abort point, control-flow and regions ! info. And for N over four, '-fsched-verbose' also includes dependence info. ! '-save-temps' ! '-save-temps=cwd' Store the usual "temporary" intermediate files permanently; place them in the current directory and name them based on the source ! file. Thus, compiling 'foo.c' with '-c -save-temps' produces files ! 'foo.i' and 'foo.s', as well as 'foo.o'. This creates a ! preprocessed 'foo.i' output file even though the compiler now normally uses an integrated preprocessor. ! When used in combination with the '-x' command-line option, !

'-save-temps=obj' Store the usual "temporary" intermediate files permanently. If the ! '-o' option is used, the temporary files are based on the object ! file. If the '-o' option is not used, the '-save-temps=obj' switch ! behaves like '-save-temps'. For example: *************** program or GCC: *** 5805,5814 **** gcc -save-temps=obj -c bar.c -o dir/xbar.o gcc -save-temps=obj foobar.c -o dir2/yfoobar ! creates `foo.i', `foo.s', `dir/xbar.i', `dir/xbar.s', ! `dir2/yfoobar.i', `dir2/yfoobar.s', and `dir2/yfoobar.o'. ! `-time[=FILE]' Report the CPU time taken by each subprocess in the compilation sequence.

Disregard strict standards compliance. `-Ofast' enables all `-O3' optimizations. It also enables optimizations that are not valid ! for all standard-compliant programs. It turns on `-ffast-math' ! and the Fortran-specific `-fno-protect-parens' and ! `-fstack-arrays'. ! `-Og' ! Optimize debugging experience. `-Og' enables optimizations that ! do not interfere with debugging. It should be the optimization ! level of choice for the standard edit-compile-debug cycle, offering ! a reasonable level of optimization while maintaining fast ! compilation and a good debugging experience. ! If you use multiple `-O' options, with or without level numbers, the last such option is the one that is effective. ! Options of the form `-fFLAG' specify machine-independent flags.

You can figure out the other form ! by either removing `no-' or adding it. The following options control specific optimizations. They are either ! activated by `-O' options or are related to ones that are. You can use the following flags in the rare cases when "fine-tuning" of optimizations to be performed is desired. ! `-fno-default-inline' Do not make member functions inline by default merely because they ! are defined inside the class scope (C++ only). Otherwise, when ! you specify `-O', member functions defined inside class scope are ! compiled inline by default; i.e., you don't need to add `inline' ! in front of the member function name. ! `-fno-defer-pop' Always pop the arguments to each function call as soon as that function returns. For machines that must pop arguments after a function call, the compiler normally lets arguments accumulate on the stack for several function calls and pops them all at once. ! Disabled at levels `-O', `-O2', `-O3', `-Os'. ! `-fforward-propagate' Perform a forward propagation pass on RTL. The pass tries to combine two instructions and checks if the result can be simplified.

This option is enabled by default at optimization levels `-O', ! `-O2', `-O3', `-Os'. ! `-ffp-contract=STYLE' ! `-ffp-contract=off' disables floating-point expression contraction. ! `-ffp-contract=fast' enables floating-point expression contraction such as forming of fused multiply-add operations if the target has ! native support for them. `-ffp-contract=on' enables ! floating-point expression contraction if allowed by the language ! standard. This is currently not implemented and treated equal to ! `-ffp-contract=off'. ! The default is `-ffp-contract=fast'. ! `-fomit-frame-pointer' ! Don't keep the frame pointer in a register for functions that ! don't need one. This avoids the instructions to save, set up and ! restore frame pointers; it also makes an extra register available ! in many functions. *It also makes debugging impossible on some ! machines.* On some machines, such as the VAX, this flag has no effect, because the standard calling sequence automatically handles the frame pointer and nothing is saved by pretending it doesn't exist.

The default is `-ffunction-cse' ! `-fno-zero-initialized-in-bss' ! If the target supports a BSS section, GCC by default puts ! variables that are initialized to zero into BSS. This can save ! space in the resulting code. This option turns off this behavior because some programs explicitly rely on variables going to the data section--e.g., so that the resulting executable can find the beginning of that section and/or make assumptions based on that. ! The default is `-fzero-initialized-in-bss'. ! `-fmudflap -fmudflapth -fmudflapir' For front-ends that support it (C and C++), instrument all risky pointer/array dereferencing operations, some standard library string/heap functions, and some other associated constructs with range/validity tests. Modules so instrumented should be immune to buffer overflows, invalid heap use, and some other classes of C/C++ programming errors. The instrumentation relies on a separate ! runtime library (`libmudflap'), which is linked into a program if ! `-fmudflap' is given at link time. Run-time behavior of the ! instrumented program is controlled by the `MUDFLAP_OPTIONS' ! environment variable. See `env MUDFLAP_OPTIONS=-help a.out' for its options. ! Use `-fmudflapth' instead of `-fmudflap' to compile and to link if ! your program is multi-threaded. Use `-fmudflapir', in addition to ! `-fmudflap' or `-fmudflapth', if instrumentation should ignore pointer reads. This produces less instrumentation (and therefore faster execution) and still provides some protection against ! outright memory corrupting writes, but allows erroneously read ! data to propagate within a program. ! `-fthread-jumps' Perform optimizations that check to see if a jump branches to a location where another comparison subsumed by the first is found. If so, the first branch is redirected to either the destination of ! the second branch or a point immediately following it, depending ! on whether the condition is known to be true or false. ! Enabled at levels `-O2', `-O3', `-Os'. ! `-fsplit-wide-types' ! When using a type that occupies multiple registers, such as `long long' on a 32-bit system, split the registers apart and allocate them independently. This normally generates better code for those types, but may make debugging more difficult. ! Enabled at levels `-O', `-O2', `-O3', `-Os'. ! `-fcse-follow-jumps' In common subexpression elimination (CSE), scan through jump instructions when the target of the jump is not reached by any ! other path. For example, when CSE encounters an `if' statement ! with an `else' clause, CSE follows the jump when the condition tested is false. ! Enabled at levels `-O2', `-O3', `-Os'. ! `-fcse-skip-blocks' ! This is similar to `-fcse-follow-jumps', but causes CSE to follow jumps that conditionally skip over blocks. When CSE encounters a ! simple `if' statement with no else clause, `-fcse-skip-blocks' ! causes CSE to follow the jump around the body of the `if'. ! Enabled at levels `-O2', `-O3', `-Os'. ! `-frerun-cse-after-loop' Re-run common subexpression elimination after loop optimizations are performed. ! Enabled at levels `-O2', `-O3', `-Os'. ! `-fgcse' Perform a global common subexpression elimination pass. This pass also performs global constant and copy propagation. _Note:_ When compiling a program using computed gotos, a GCC extension, you may get better run-time performance if you disable the global common subexpression elimination pass by adding ! `-fno-gcse' to the command line. ! Enabled at levels `-O2', `-O3', `-Os'. ! `-fgcse-lm' ! When `-fgcse-lm' is enabled, global common subexpression elimination attempts to move loads that are only killed by stores into themselves. This allows a loop containing a load/store ! sequence to be changed to a load outside the loop, and a ! copy/store within the loop. ! Enabled by default when `-fgcse' is enabled. ! `-fgcse-sm' ! When `-fgcse-sm' is enabled, a store motion pass is run after global common subexpression elimination. This pass attempts to move stores out of loops. When used in conjunction with ! `-fgcse-lm', loops containing a load/store sequence can be changed to a load before the loop and a store after the loop. Not enabled at any optimization level. ! `-fgcse-las' ! When `-fgcse-las' is enabled, the global common subexpression elimination pass eliminates redundant loads that come after stores to the same memory location (both partial and full redundancies). Not enabled at any optimization level. ! `-fgcse-after-reload' ! When `-fgcse-after-reload' is enabled, a redundant load elimination pass is performed after reload. The purpose of this pass is to clean up redundant spilling. ! `-faggressive-loop-optimizations' This option tells the loop optimizer to use language constraints to ! derive bounds for the number of iterations of a loop. This ! assumes that loop code does not invoke undefined behavior by for ! example causing signed integer overflows or out-of-bound array ! accesses. The bounds for the number of iterations of a loop are ! used to guide loop unrolling and peeling and loop exit test ! optimizations. This option is enabled by default. ! `-funsafe-loop-optimizations' ! This option tells the loop optimizer to assume that loop indices ! do not overflow, and that loops with nontrivial exit condition are ! not infinite. This enables a wider range of loop optimizations ! even if the loop optimizer itself cannot prove that these ! assumptions are valid. If you use `-Wunsafe-loop-optimizations', ! the compiler warns you if it finds this kind of loop. ! `-fcrossjumping' Perform cross-jumping transformation. This transformation unifies ! equivalent code and saves code size. The resulting code may or ! may not perform better than without cross-jumping. ! Enabled at levels `-O2', `-O3', `-Os'. ! `-fauto-inc-dec' Combine increments or decrements of addresses with memory accesses. This pass is always skipped on architectures that do not have ! instructions to support this. Enabled by default at `-O' and higher on architectures that support this. ! `-fdce' Perform dead code elimination (DCE) on RTL. Enabled by default at ! `-O' and higher. ! `-fdse' ! Perform dead store elimination (DSE) on RTL. Enabled by default ! at `-O' and higher. ! `-fif-conversion' Attempt to transform conditional jumps into branch-less ! equivalents. This includes use of conditional moves, min, max, ! set flags and abs instructions, and some tricks doable by standard ! arithmetics. The use of conditional execution on chips where it ! is available is controlled by `if-conversion2'. ! Enabled at levels `-O', `-O2', `-O3', `-Os'. ! `-fif-conversion2' Use conditional execution (where available) to transform conditional jumps into branch-less equivalents. ! Enabled at levels `-O', `-O2', `-O3', `-Os'. ! `-fdelete-null-pointer-checks' Assume that programs cannot safely dereference null pointers, and that no code or data element resides there. This enables simple constant folding optimizations at all optimization levels. In ! addition, other optimization passes in GCC use this flag to ! control global dataflow analyses that eliminate useless checks for ! null pointers; these assume that if a pointer is checked after it ! has already been dereferenced, it cannot be null. Note however that in some environments this assumption is not true. ! Use `-fno-delete-null-pointer-checks' to disable this optimization for programs that depend on that behavior. Some targets, especially embedded ones, disable this option at all ! levels. Otherwise it is enabled at all levels: `-O0', `-O1', ! `-O2', `-O3', `-Os'. Passes that use the information are enabled independently at different optimization levels. ! `-fdevirtualize' Attempt to convert calls to virtual functions to direct calls. This is done both within a procedure and interprocedurally as part ! of indirect inlining (`-findirect-inlining') and interprocedural ! constant propagation (`-fipa-cp'). Enabled at levels `-O2', ! `-O3', `-Os'. ! `-fexpensive-optimizations' Perform a number of minor optimizations that are relatively expensive. ! Enabled at levels `-O2', `-O3', `-Os'. ! `-free' Attempt to remove redundant extension instructions. This is especially helpful for the x86-64 architecture, which implicitly zero-extends in 64-bit registers after writing to their lower 32-bit half. ! Enabled for x86 at levels `-O2', `-O3'. ! `-foptimize-register-move' ! `-fregmove' Attempt to reassign register numbers in move instructions and as operands of other simple instructions in order to maximize the amount of register tying. This is especially helpful on machines with two-operand instructions. ! Note `-fregmove' and `-foptimize-register-move' are the same optimization. ! Enabled at levels `-O2', `-O3', `-Os'. ! `-fira-algorithm=ALGORITHM' Use the specified coloring algorithm for the integrated register ! allocator. The ALGORITHM argument can be `priority', which ! specifies Chow's priority coloring, or `CB', which specifies Chaitin-Briggs coloring. Chaitin-Briggs coloring is not implemented for all architectures, but for those targets that do support it, it is the default because it generates better code. ! `-fira-region=REGION' Use specified regions for the integrated register allocator. The REGION argument should be one of the following: ! `all' Use all loops as register allocation regions. This can give the best results for machines with a small and/or irregular register set. ! `mixed' ! Use all loops except for loops with small register pressure ! as the regions. This value usually gives the best results in most cases and for most architectures, and is enabled by ! default when compiling with optimization for speed (`-O', ! `-O2', ...). ! `one' Use all functions as a single region. This typically results ! in the smallest code size, and is enabled by default for ! `-Os' or `-O0'. ! ! `-fira-hoist-pressure' Use IRA to evaluate register pressure in the code hoisting pass for decisions to hoist expressions. This option usually results in smaller code, but it can slow the compiler down. ! This option is enabled at level `-Os' for all targets. ! `-fira-loop-pressure' Use IRA to evaluate register pressure in loops for decisions to ! move loop invariants. This option usually results in generation ! of faster and smaller code on machines with large register files ! (>= 32 registers), but it can slow the compiler down. ! This option is enabled at level `-O3' for some targets. ! `-fno-ira-share-save-slots' Disable sharing of stack slots used for saving call-used hard registers living through a call. Each hard register gets a separate stack slot, and as a result function stack frames are larger. ! `-fno-ira-share-spill-slots' Disable sharing of stack slots allocated for pseudo-registers. Each pseudo-register that does not get a hard register gets a separate stack slot, and as a result function stack frames are larger. ! `-fira-verbose=N' Control the verbosity of the dump file for the integrated register allocator. The default value is 5. If the value N is greater or equal to 10, the dump output is sent to stderr using the same format as N minus 10. ! `-fdelayed-branch' If supported for the target machine, attempt to reorder instructions to exploit instruction slots available after delayed branch instructions. ! Enabled at levels `-O', `-O2', `-O3', `-Os'. ! `-fschedule-insns' If supported for the target machine, attempt to reorder instructions to eliminate execution stalls due to required data being unavailable. This helps machines that have slow floating ! point or memory load instructions by allowing other instructions ! to be issued until the result of the load or floating-point instruction is required. ! Enabled at levels `-O2', `-O3'. ! `-fschedule-insns2' ! Similar to `-fschedule-insns', but requests an additional pass of instruction scheduling after register allocation has been done. This is especially useful on machines with a relatively small number of registers and where memory load instructions take more than one cycle. ! Enabled at levels `-O2', `-O3', `-Os'. ! `-fno-sched-interblock' Don't schedule instructions across basic blocks. This is normally enabled by default when scheduling before register allocation, i.e. ! with `-fschedule-insns' or at `-O2' or higher. ! `-fno-sched-spec' Don't allow speculative motion of non-load instructions. This is normally enabled by default when scheduling before register ! allocation, i.e. with `-fschedule-insns' or at `-O2' or higher. ! `-fsched-pressure' Enable register pressure sensitive insn scheduling before register allocation. This only makes sense when scheduling before register ! allocation is enabled, i.e. with `-fschedule-insns' or at `-O2' or higher. Usage of this option can improve the generated code and decrease its size by preventing register pressure increase above the number of available hard registers and subsequent spills in register allocation. ! `-fsched-spec-load' Allow speculative motion of some load instructions. This only makes sense when scheduling before register allocation, i.e. with ! `-fschedule-insns' or at `-O2' or higher. ! `-fsched-spec-load-dangerous' Allow speculative motion of more load instructions. This only makes sense when scheduling before register allocation, i.e. with ! `-fschedule-insns' or at `-O2' or higher. ! `-fsched-stalled-insns' ! `-fsched-stalled-insns=N' Define how many insns (if any) can be moved prematurely from the queue of stalled insns into the ready list during the second ! scheduling pass. `-fno-sched-stalled-insns' means that no insns ! are moved prematurely, `-fsched-stalled-insns=0' means there is no limit on how many queued insns can be moved prematurely. ! `-fsched-stalled-insns' without a value is equivalent to ! `-fsched-stalled-insns=1'. ! `-fsched-stalled-insns-dep' ! `-fsched-stalled-insns-dep=N' Define how many insn groups (cycles) are examined for a dependency on a stalled insn that is a candidate for premature removal from the queue of stalled insns. This has an effect only during the ! second scheduling pass, and only if `-fsched-stalled-insns' is ! used. `-fno-sched-stalled-insns-dep' is equivalent to ! `-fsched-stalled-insns-dep=0'. `-fsched-stalled-insns-dep' ! without a value is equivalent to `-fsched-stalled-insns-dep=1'. ! `-fsched2-use-superblocks' When scheduling after register allocation, use superblock scheduling. This allows motion across basic block boundaries, ! resulting in faster schedules. This option is experimental, as ! not all machine descriptions used by GCC model the CPU closely ! enough to avoid unreliable results from the algorithm. This only makes sense when scheduling after register allocation, ! i.e. with `-fschedule-insns2' or at `-O2' or higher. ! `-fsched-group-heuristic' Enable the group heuristic in the scheduler. This heuristic favors the instruction that belongs to a schedule group. This is enabled ! by default when scheduling is enabled, i.e. with `-fschedule-insns' ! or `-fschedule-insns2' or at `-O2' or higher. ! `-fsched-critical-path-heuristic' Enable the critical-path heuristic in the scheduler. This heuristic favors instructions on the critical path. This is enabled by default when scheduling is enabled, i.e. with ! `-fschedule-insns' or `-fschedule-insns2' or at `-O2' or higher. ! `-fsched-spec-insn-heuristic' Enable the speculative instruction heuristic in the scheduler. This heuristic favors speculative instructions with greater ! dependency weakness. This is enabled by default when scheduling ! is enabled, i.e. with `-fschedule-insns' or `-fschedule-insns2' ! or at `-O2' or higher. ! `-fsched-rank-heuristic' Enable the rank heuristic in the scheduler. This heuristic favors the instruction belonging to a basic block with greater size or frequency. This is enabled by default when scheduling is enabled, ! i.e. with `-fschedule-insns' or `-fschedule-insns2' or at `-O2' ! or higher. ! `-fsched-last-insn-heuristic' Enable the last-instruction heuristic in the scheduler. This ! heuristic favors the instruction that is less dependent on the ! last instruction scheduled. This is enabled by default when ! scheduling is enabled, i.e. with `-fschedule-insns' or ! `-fschedule-insns2' or at `-O2' or higher. ! `-fsched-dep-count-heuristic' Enable the dependent-count heuristic in the scheduler. This heuristic favors the instruction that has more instructions depending on it. This is enabled by default when scheduling is ! enabled, i.e. with `-fschedule-insns' or `-fschedule-insns2' or ! at `-O2' or higher. ! `-freschedule-modulo-scheduled-loops' ! Modulo scheduling is performed before traditional scheduling. If ! a loop is modulo scheduled, later scheduling passes may change its schedule. Use this option to control that behavior. ! `-fselective-scheduling' Schedule instructions using selective scheduling algorithm. Selective scheduling runs instead of the first scheduler pass. ! `-fselective-scheduling2' Schedule instructions using selective scheduling algorithm. Selective scheduling runs instead of the second scheduler pass. ! `-fsel-sched-pipelining' Enable software pipelining of innermost loops during selective scheduling. This option has no effect unless one of ! `-fselective-scheduling' or `-fselective-scheduling2' is turned on. ! `-fsel-sched-pipelining-outer-loops' When pipelining loops during selective scheduling, also pipeline outer loops. This option has no effect unless ! `-fsel-sched-pipelining' is turned on. ! `-fshrink-wrap' ! Emit function prologues only before parts of the function that ! need it, rather than at the top of the function. This flag is ! enabled by default at `-O' and higher. ! `-fcaller-saves' Enable allocation of values to registers that are clobbered by function calls, by emitting extra instructions to save and restore ! the registers around such calls. Such allocation is done only ! when it seems to result in better code. This option is always enabled by default on certain machines, usually those which have no call-preserved registers to use instead. ! Enabled at levels `-O2', `-O3', `-Os'. ! `-fcombine-stack-adjustments' Tracks stack adjustments (pushes and pops) and stack memory references and then tries to find ways to combine them. ! Enabled by default at `-O1' and higher. ! `-fconserve-stack' Attempt to minimize stack usage. The compiler attempts to use less stack space, even if that makes the program slower. This option ! implies setting the `large-stack-frame' parameter to 100 and the ! `large-stack-frame-growth' parameter to 400. ! `-ftree-reassoc' ! Perform reassociation on trees. This flag is enabled by default ! at `-O' and higher. ! `-ftree-pre' Perform partial redundancy elimination (PRE) on trees. This flag ! is enabled by default at `-O2' and `-O3'. ! `-ftree-partial-pre' Make partial redundancy elimination (PRE) more aggressive. This ! flag is enabled by default at `-O3'. ! `-ftree-forwprop' Perform forward propagation on trees. This flag is enabled by ! default at `-O' and higher. ! `-ftree-fre' Perform full redundancy elimination (FRE) on trees. The difference ! between FRE and PRE is that FRE only considers expressions that ! are computed on all paths leading to the redundant computation. ! This analysis is faster than PRE, though it exposes fewer ! redundancies. This flag is enabled by default at `-O' and higher. ! `-ftree-phiprop' Perform hoisting of loads from conditional pointers on trees. This ! pass is enabled by default at `-O' and higher. ! `-fhoist-adjacent-loads' Speculatively hoist loads from both branches of an if-then-else if ! the loads are from adjacent locations in the same structure and ! the target architecture has a conditional move instruction. This ! flag is enabled by default at `-O2' and higher. ! `-ftree-copy-prop' Perform copy propagation on trees. This pass eliminates unnecessary copy operations. This flag is enabled by default at ! `-O' and higher. ! `-fipa-pure-const' Discover which functions are pure or constant. Enabled by default ! at `-O' and higher. ! `-fipa-reference' Discover which static variables do not escape the compilation unit. ! Enabled by default at `-O' and higher. ! `-fipa-pta' Perform interprocedural pointer analysis and interprocedural modification and reference analysis. This option can cause ! excessive memory and compile-time usage on large compilation ! units. It is not enabled by default at any optimization level. ! `-fipa-profile' Perform interprocedural profile propagation. The functions called ! only from cold functions are marked as cold. Also functions ! executed once (such as `cold', `noreturn', static constructors or ! destructors) are identified. Cold functions and loop less parts of functions executed once are then optimized for size. Enabled by ! default at `-O' and higher. ! `-fipa-cp' Perform interprocedural constant propagation. This optimization analyzes the program to determine when values passed to functions are constants and then optimizes accordingly. This optimization can substantially increase performance if the application has constants passed to functions. This flag is enabled by default at ! `-O2', `-Os' and `-O3'. ! `-fipa-cp-clone' Perform function cloning to make interprocedural constant propagation stronger. When enabled, interprocedural constant propagation performs function cloning when externally visible function can be called with constant arguments. Because this optimization can create multiple copies of functions, it may ! significantly increase code size (see `--param ipcp-unit-growth=VALUE'). This flag is enabled by default at ! `-O3'. ! `-ftree-sink' ! Perform forward store motion on trees. This flag is enabled by ! default at `-O' and higher. ! `-ftree-bit-ccp' Perform sparse conditional bit constant propagation on trees and propagate pointer alignment information. This pass only operates ! on local scalar variables and is enabled by default at `-O' and ! higher. It requires that `-ftree-ccp' is enabled. ! `-ftree-ccp' Perform sparse conditional constant propagation (CCP) on trees. ! This pass only operates on local scalar variables and is enabled ! by default at `-O' and higher. ! `-ftree-switch-conversion' Perform conversion of simple initializations in a switch to initializations from a scalar array. This flag is enabled by ! default at `-O2' and higher. ! `-ftree-tail-merge' Look for identical code sequences. When found, replace one with a jump to the other. This optimization is known as tail merging or ! cross jumping. This flag is enabled by default at `-O2' and higher. The compilation time in this pass can be limited using ! `max-tail-merge-comparisons' parameter and ! `max-tail-merge-iterations' parameter. ! `-ftree-dce' ! Perform dead code elimination (DCE) on trees. This flag is ! enabled by default at `-O' and higher. ! `-ftree-builtin-call-dce' Perform conditional dead code elimination (DCE) for calls to ! built-in functions that may set `errno' but are otherwise ! side-effect free. This flag is enabled by default at `-O2' and ! higher if `-Os' is not also specified. ! `-ftree-dominator-opts' Perform a variety of simple scalar cleanups (constant/copy propagation, redundancy elimination, range propagation and expression simplification) based on a dominator tree traversal. ! This also performs jump threading (to reduce jumps to jumps). This ! flag is enabled by default at `-O' and higher. ! `-ftree-dse' Perform dead store elimination (DSE) on trees. A dead store is a store into a memory location that is later overwritten by another store without any intervening loads. In this case the earlier ! store can be deleted. This flag is enabled by default at `-O' and higher. ! `-ftree-ch' Perform loop header copying on trees. This is beneficial since it increases effectiveness of code motion optimizations. It also ! saves one jump. This flag is enabled by default at `-O' and ! higher. It is not enabled for `-Os', since it usually increases code size. ! `-ftree-loop-optimize' Perform loop optimizations on trees. This flag is enabled by ! default at `-O' and higher. ! `-ftree-loop-linear' Perform loop interchange transformations on tree. Same as ! `-floop-interchange'. To use this code transformation, GCC has to ! be configured with `--with-ppl' and `--with-cloog' to enable the Graphite loop transformation infrastructure. ! `-floop-interchange' Perform loop interchange transformations on loops. Interchanging two nested loops switches the inner and outer loops. For example, given a loop like: --- 6273,6885 ---- that alter the assembler output may be confused by the optimizations performed when this option is not used. ! The default is '-ffunction-cse' ! '-fno-zero-initialized-in-bss' ! If the target supports a BSS section, GCC by default puts variables ! that are initialized to zero into BSS. This can save space in the ! resulting code. This option turns off this behavior because some programs explicitly rely on variables going to the data section--e.g., so that the resulting executable can find the beginning of that section and/or make assumptions based on that. ! The default is '-fzero-initialized-in-bss'. ! '-fmudflap -fmudflapth -fmudflapir' For front-ends that support it (C and C++), instrument all risky pointer/array dereferencing operations, some standard library string/heap functions, and some other associated constructs with range/validity tests. Modules so instrumented should be immune to buffer overflows, invalid heap use, and some other classes of C/C++ programming errors. The instrumentation relies on a separate ! runtime library ('libmudflap'), which is linked into a program if ! '-fmudflap' is given at link time. Run-time behavior of the ! instrumented program is controlled by the 'MUDFLAP_OPTIONS' ! environment variable. See 'env MUDFLAP_OPTIONS=-help a.out' for its options. ! Use '-fmudflapth' instead of '-fmudflap' to compile and to link if ! your program is multi-threaded. Use '-fmudflapir', in addition to ! '-fmudflap' or '-fmudflapth', if instrumentation should ignore pointer reads. This produces less instrumentation (and therefore faster execution) and still provides some protection against ! outright memory corrupting writes, but allows erroneously read data ! to propagate within a program. ! '-fthread-jumps' Perform optimizations that check to see if a jump branches to a location where another comparison subsumed by the first is found. If so, the first branch is redirected to either the destination of ! the second branch or a point immediately following it, depending on ! whether the condition is known to be true or false. ! Enabled at levels '-O2', '-O3', '-Os'. ! '-fsplit-wide-types' ! When using a type that occupies multiple registers, such as 'long long' on a 32-bit system, split the registers apart and allocate them independently. This normally generates better code for those types, but may make debugging more difficult. ! Enabled at levels '-O', '-O2', '-O3', '-Os'. ! '-fcse-follow-jumps' In common subexpression elimination (CSE), scan through jump instructions when the target of the jump is not reached by any ! other path. For example, when CSE encounters an 'if' statement ! with an 'else' clause, CSE follows the jump when the condition tested is false. ! Enabled at levels '-O2', '-O3', '-Os'. ! '-fcse-skip-blocks' ! This is similar to '-fcse-follow-jumps', but causes CSE to follow jumps that conditionally skip over blocks. When CSE encounters a ! simple 'if' statement with no else clause, '-fcse-skip-blocks' ! causes CSE to follow the jump around the body of the 'if'. ! Enabled at levels '-O2', '-O3', '-Os'. ! '-frerun-cse-after-loop' Re-run common subexpression elimination after loop optimizations are performed. ! Enabled at levels '-O2', '-O3', '-Os'. ! '-fgcse' Perform a global common subexpression elimination pass. This pass also performs global constant and copy propagation. _Note:_ When compiling a program using computed gotos, a GCC extension, you may get better run-time performance if you disable the global common subexpression elimination pass by adding ! '-fno-gcse' to the command line. ! Enabled at levels '-O2', '-O3', '-Os'. ! '-fgcse-lm' ! When '-fgcse-lm' is enabled, global common subexpression elimination attempts to move loads that are only killed by stores into themselves. This allows a loop containing a load/store ! sequence to be changed to a load outside the loop, and a copy/store ! within the loop. ! Enabled by default when '-fgcse' is enabled. ! '-fgcse-sm' ! When '-fgcse-sm' is enabled, a store motion pass is run after global common subexpression elimination. This pass attempts to move stores out of loops. When used in conjunction with ! '-fgcse-lm', loops containing a load/store sequence can be changed to a load before the loop and a store after the loop. Not enabled at any optimization level. ! '-fgcse-las' ! When '-fgcse-las' is enabled, the global common subexpression elimination pass eliminates redundant loads that come after stores to the same memory location (both partial and full redundancies). Not enabled at any optimization level. ! '-fgcse-after-reload' ! When '-fgcse-after-reload' is enabled, a redundant load elimination pass is performed after reload. The purpose of this pass is to clean up redundant spilling. ! '-faggressive-loop-optimizations' This option tells the loop optimizer to use language constraints to ! derive bounds for the number of iterations of a loop. This assumes ! that loop code does not invoke undefined behavior by for example ! causing signed integer overflows or out-of-bound array accesses. ! The bounds for the number of iterations of a loop are used to guide ! loop unrolling and peeling and loop exit test optimizations. This ! option is enabled by default. ! '-funsafe-loop-optimizations' ! This option tells the loop optimizer to assume that loop indices do ! not overflow, and that loops with nontrivial exit condition are not ! infinite. This enables a wider range of loop optimizations even if ! the loop optimizer itself cannot prove that these assumptions are ! valid. If you use '-Wunsafe-loop-optimizations', the compiler ! warns you if it finds this kind of loop. ! '-fcrossjumping' Perform cross-jumping transformation. This transformation unifies ! equivalent code and saves code size. The resulting code may or may ! not perform better than without cross-jumping. ! Enabled at levels '-O2', '-O3', '-Os'. ! '-fauto-inc-dec' Combine increments or decrements of addresses with memory accesses. This pass is always skipped on architectures that do not have ! instructions to support this. Enabled by default at '-O' and higher on architectures that support this. ! '-fdce' Perform dead code elimination (DCE) on RTL. Enabled by default at ! '-O' and higher. ! '-fdse' ! Perform dead store elimination (DSE) on RTL. Enabled by default at ! '-O' and higher. ! '-fif-conversion' Attempt to transform conditional jumps into branch-less ! equivalents. This includes use of conditional moves, min, max, set ! flags and abs instructions, and some tricks doable by standard ! arithmetics. The use of conditional execution on chips where it is ! available is controlled by 'if-conversion2'. ! Enabled at levels '-O', '-O2', '-O3', '-Os'. ! '-fif-conversion2' Use conditional execution (where available) to transform conditional jumps into branch-less equivalents. ! Enabled at levels '-O', '-O2', '-O3', '-Os'. ! '-fdelete-null-pointer-checks' Assume that programs cannot safely dereference null pointers, and that no code or data element resides there. This enables simple constant folding optimizations at all optimization levels. In ! addition, other optimization passes in GCC use this flag to control ! global dataflow analyses that eliminate useless checks for null ! pointers; these assume that if a pointer is checked after it has ! already been dereferenced, it cannot be null. Note however that in some environments this assumption is not true. ! Use '-fno-delete-null-pointer-checks' to disable this optimization for programs that depend on that behavior. Some targets, especially embedded ones, disable this option at all ! levels. Otherwise it is enabled at all levels: '-O0', '-O1', ! '-O2', '-O3', '-Os'. Passes that use the information are enabled independently at different optimization levels. ! '-fdevirtualize' Attempt to convert calls to virtual functions to direct calls. This is done both within a procedure and interprocedurally as part ! of indirect inlining ('-findirect-inlining') and interprocedural ! constant propagation ('-fipa-cp'). Enabled at levels '-O2', '-O3', ! '-Os'. ! '-fexpensive-optimizations' Perform a number of minor optimizations that are relatively expensive. ! Enabled at levels '-O2', '-O3', '-Os'. ! '-free' Attempt to remove redundant extension instructions. This is especially helpful for the x86-64 architecture, which implicitly zero-extends in 64-bit registers after writing to their lower 32-bit half. ! Enabled for x86 at levels '-O2', '-O3'. ! '-foptimize-register-move' ! '-fregmove' Attempt to reassign register numbers in move instructions and as operands of other simple instructions in order to maximize the amount of register tying. This is especially helpful on machines with two-operand instructions. ! Note '-fregmove' and '-foptimize-register-move' are the same optimization. ! Enabled at levels '-O2', '-O3', '-Os'. ! '-fira-algorithm=ALGORITHM' Use the specified coloring algorithm for the integrated register ! allocator. The ALGORITHM argument can be 'priority', which ! specifies Chow's priority coloring, or 'CB', which specifies Chaitin-Briggs coloring. Chaitin-Briggs coloring is not implemented for all architectures, but for those targets that do support it, it is the default because it generates better code. ! '-fira-region=REGION' Use specified regions for the integrated register allocator. The REGION argument should be one of the following: ! 'all' Use all loops as register allocation regions. This can give the best results for machines with a small and/or irregular register set. ! 'mixed' ! Use all loops except for loops with small register pressure as ! the regions. This value usually gives the best results in most cases and for most architectures, and is enabled by ! default when compiling with optimization for speed ('-O', ! '-O2', ...). ! 'one' Use all functions as a single region. This typically results ! in the smallest code size, and is enabled by default for '-Os' ! or '-O0'. ! '-fira-hoist-pressure' Use IRA to evaluate register pressure in the code hoisting pass for decisions to hoist expressions. This option usually results in smaller code, but it can slow the compiler down. ! This option is enabled at level '-Os' for all targets. ! '-fira-loop-pressure' Use IRA to evaluate register pressure in loops for decisions to ! move loop invariants. This option usually results in generation of ! faster and smaller code on machines with large register files (>= ! 32 registers), but it can slow the compiler down. ! This option is enabled at level '-O3' for some targets. ! '-fno-ira-share-save-slots' Disable sharing of stack slots used for saving call-used hard registers living through a call. Each hard register gets a separate stack slot, and as a result function stack frames are larger. ! '-fno-ira-share-spill-slots' Disable sharing of stack slots allocated for pseudo-registers. Each pseudo-register that does not get a hard register gets a separate stack slot, and as a result function stack frames are larger. ! '-fira-verbose=N' Control the verbosity of the dump file for the integrated register allocator. The default value is 5. If the value N is greater or equal to 10, the dump output is sent to stderr using the same format as N minus 10. ! '-fdelayed-branch' If supported for the target machine, attempt to reorder instructions to exploit instruction slots available after delayed branch instructions. ! Enabled at levels '-O', '-O2', '-O3', '-Os'. ! '-fschedule-insns' If supported for the target machine, attempt to reorder instructions to eliminate execution stalls due to required data being unavailable. This helps machines that have slow floating ! point or memory load instructions by allowing other instructions to ! be issued until the result of the load or floating-point instruction is required. ! Enabled at levels '-O2', '-O3'. ! '-fschedule-insns2' ! Similar to '-fschedule-insns', but requests an additional pass of instruction scheduling after register allocation has been done. This is especially useful on machines with a relatively small number of registers and where memory load instructions take more than one cycle. ! Enabled at levels '-O2', '-O3', '-Os'. ! '-fno-sched-interblock' Don't schedule instructions across basic blocks. This is normally enabled by default when scheduling before register allocation, i.e. ! with '-fschedule-insns' or at '-O2' or higher. ! '-fno-sched-spec' Don't allow speculative motion of non-load instructions. This is normally enabled by default when scheduling before register ! allocation, i.e. with '-fschedule-insns' or at '-O2' or higher. ! '-fsched-pressure' Enable register pressure sensitive insn scheduling before register allocation. This only makes sense when scheduling before register ! allocation is enabled, i.e. with '-fschedule-insns' or at '-O2' or higher. Usage of this option can improve the generated code and decrease its size by preventing register pressure increase above the number of available hard registers and subsequent spills in register allocation. ! '-fsched-spec-load' Allow speculative motion of some load instructions. This only makes sense when scheduling before register allocation, i.e. with ! '-fschedule-insns' or at '-O2' or higher. ! '-fsched-spec-load-dangerous' Allow speculative motion of more load instructions. This only makes sense when scheduling before register allocation, i.e. with ! '-fschedule-insns' or at '-O2' or higher. ! '-fsched-stalled-insns' ! '-fsched-stalled-insns=N' Define how many insns (if any) can be moved prematurely from the queue of stalled insns into the ready list during the second ! scheduling pass. '-fno-sched-stalled-insns' means that no insns ! are moved prematurely, '-fsched-stalled-insns=0' means there is no limit on how many queued insns can be moved prematurely. ! '-fsched-stalled-insns' without a value is equivalent to ! '-fsched-stalled-insns=1'. ! '-fsched-stalled-insns-dep' ! '-fsched-stalled-insns-dep=N' Define how many insn groups (cycles) are examined for a dependency on a stalled insn that is a candidate for premature removal from the queue of stalled insns. This has an effect only during the ! second scheduling pass, and only if '-fsched-stalled-insns' is ! used. '-fno-sched-stalled-insns-dep' is equivalent to ! '-fsched-stalled-insns-dep=0'. '-fsched-stalled-insns-dep' without ! a value is equivalent to '-fsched-stalled-insns-dep=1'. ! '-fsched2-use-superblocks' When scheduling after register allocation, use superblock scheduling. This allows motion across basic block boundaries, ! resulting in faster schedules. This option is experimental, as not ! all machine descriptions used by GCC model the CPU closely enough ! to avoid unreliable results from the algorithm. This only makes sense when scheduling after register allocation, ! i.e. with '-fschedule-insns2' or at '-O2' or higher. ! '-fsched-group-heuristic' Enable the group heuristic in the scheduler. This heuristic favors the instruction that belongs to a schedule group. This is enabled ! by default when scheduling is enabled, i.e. with '-fschedule-insns' ! or '-fschedule-insns2' or at '-O2' or higher. ! '-fsched-critical-path-heuristic' Enable the critical-path heuristic in the scheduler. This heuristic favors instructions on the critical path. This is enabled by default when scheduling is enabled, i.e. with ! '-fschedule-insns' or '-fschedule-insns2' or at '-O2' or higher. ! '-fsched-spec-insn-heuristic' Enable the speculative instruction heuristic in the scheduler. This heuristic favors speculative instructions with greater ! dependency weakness. This is enabled by default when scheduling is ! enabled, i.e. with '-fschedule-insns' or '-fschedule-insns2' or at ! '-O2' or higher. !

This flag is enabled by default at ! '-O' and higher. ! '-ftree-pre' Perform partial redundancy elimination (PRE) on trees. This flag ! is enabled by default at '-O2' and '-O3'. ! '-ftree-partial-pre' Make partial redundancy elimination (PRE) more aggressive. This ! flag is enabled by default at '-O3'. ! '-ftree-forwprop' Perform forward propagation on trees.

'gcc-nm', 'gcc-ranlib' wrappers to pass the right options to these ! tools. With non fat LTO makefiles need to be modified to use them. ! The default is '-ffat-lto-objects' but this default is intended to change in future releases when linker plugin enabled environments become more common. ! '-fcompare-elim' After register allocation and post-register allocation instruction splitting, identify arithmetic instructions that compute processor flags similar to a comparison operation based on that arithmetic. *************** optimizations to be performed is desired *** 7751,8073 **** represent the comparison operation before register allocation is complete. ! Enabled at levels `-O', `-O2', `-O3', `-Os'. ! `-fuse-ld=bfd' ! Use the `bfd' linker instead of the default linker. ! `-fuse-ld=gold' ! Use the `gold' linker instead of the default linker. ! `-fcprop-registers' After register allocation and post-register allocation instruction splitting, perform a copy-propagation pass to try to reduce scheduling dependencies and occasionally eliminate the copy. ! Enabled at levels `-O', `-O2', `-O3', `-Os'. ! `-fprofile-correction' Profiles collected using an instrumented binary for multi-threaded ! programs may be inconsistent due to missed counter updates. When this option is specified, GCC uses heuristics to correct or smooth ! out such inconsistencies. By default, GCC emits an error message when an inconsistent profile is detected. ! `-fprofile-dir=PATH' Set the directory to search for the profile data files in to PATH. This option affects only the profile data generated by ! `-fprofile-generate', `-ftest-coverage', `-fprofile-arcs' and used ! by `-fprofile-use' and `-fbranch-probabilities' and its related options. Both absolute and relative paths can be used. By default, GCC uses the current directory as PATH, thus the profile data file appears in the same directory as the object file. ! `-fprofile-generate' ! `-fprofile-generate=PATH' Enable options usually used for instrumenting application to produce profile useful for later recompilation with profile ! feedback based optimization. You must use `-fprofile-generate' both when compiling and when linking your program. ! The following options are enabled: `-fprofile-arcs', ! `-fprofile-values', `-fvpt'. If PATH is specified, GCC looks at the PATH to find the profile ! feedback data files. See `-fprofile-dir'. ! `-fprofile-use' ! `-fprofile-use=PATH' Enable profile feedback directed optimizations, and optimizations generally profitable only with profile feedback available. ! The following options are enabled: `-fbranch-probabilities', ! `-fvpt', `-funroll-loops', `-fpeel-loops', `-ftracer', ! `-ftree-vectorize', `ftree-loop-distribute-patterns' By default, GCC emits an error message if the feedback profiles do ! not match the source code. This error can be turned into a ! warning by using `-Wcoverage-mismatch'. Note this may result in ! poorly optimized code. If PATH is specified, GCC looks at the PATH to find the profile ! feedback data files. See `-fprofile-dir'. The following options control compiler behavior regarding floating-point arithmetic. These options trade off between speed and correctness. All must be specifically enabled. ! `-ffloat-store' Do not store floating-point variables in registers, and inhibit other options that might change whether a floating-point value is taken from a register or memory. This option prevents undesirable excess precision on machines such as the 68000 where the floating registers (of the 68881) keep more ! precision than a `double' is supposed to have. Similarly for the x86 architecture. For most programs, the excess precision does only good, but a few programs rely on the precise definition of ! IEEE floating point. Use `-ffloat-store' for such programs, after modifying them to store all pertinent intermediate computations into variables. ! `-fexcess-precision=STYLE' This option allows further control over excess precision on machines where floating-point registers have more precision than ! the IEEE `float' and `double' types and the processor does not support operations rounding to those types. By default, ! `-fexcess-precision=fast' is in effect; this means that operations are carried out in the precision of the registers and that it is unpredictable when rounding to the types specified in the source code takes place. When compiling C, if ! `-fexcess-precision=standard' is specified then excess precision follows the rules specified in ISO C99; in particular, both casts and assignments cause values to be rounded to their semantic types ! (whereas `-ffloat-store' only affects assignments). This option ! is enabled by default for C if a strict conformance option such as ! `-std=c99' is used. ! `-fexcess-precision=standard' is not implemented for languages ! other than C, and has no effect if `-funsafe-math-optimizations' ! or `-ffast-math' is specified. On the x86, it also has no effect ! if `-mfpmath=sse' or `-mfpmath=sse+387' is specified; in the ! former case, IEEE semantics apply without excess precision, and in ! the latter, rounding is unpredictable. ! `-ffast-math' ! Sets `-fno-math-errno', `-funsafe-math-optimizations', ! `-ffinite-math-only', `-fno-rounding-math', `-fno-signaling-nans' ! and `-fcx-limited-range'. ! This option causes the preprocessor macro `__FAST_MATH__' to be defined. ! This option is not turned on by any `-O' option besides `-Ofast' ! since it can result in incorrect output for programs that depend ! on an exact implementation of IEEE or ISO rules/specifications for ! math functions. It may, however, yield faster code for programs that do not require the guarantees of these specifications. ! `-fno-math-errno' ! Do not set `errno' after calling math functions that are executed ! with a single instruction, e.g., `sqrt'. A program that relies on IEEE exceptions for math error handling may want to use this flag for speed while maintaining IEEE arithmetic compatibility. ! This option is not turned on by any `-O' option since it can ! result in incorrect output for programs that depend on an exact implementation of IEEE or ISO rules/specifications for math ! functions. It may, however, yield faster code for programs that do not require the guarantees of these specifications. ! The default is `-fmath-errno'. ! On Darwin systems, the math library never sets `errno'. There is therefore no reason for the compiler to consider the possibility ! that it might, and `-fno-math-errno' is the default. - `-funsafe-math-optimizations' Allow optimizations for floating-point arithmetic that (a) assume that arguments and results are valid and (b) may violate IEEE or ANSI standards. When used at link-time, it may include libraries or startup files that change the default FPU control word or other similar optimizations. ! This option is not turned on by any `-O' option since it can ! result in incorrect output for programs that depend on an exact implementation of IEEE or ISO rules/specifications for math ! functions. It may, however, yield faster code for programs that do not require the guarantees of these specifications. Enables ! `-fno-signed-zeros', `-fno-trapping-math', `-fassociative-math' ! and `-freciprocal-math'. ! The default is `-fno-unsafe-math-optimizations'. - `-fassociative-math' Allow re-association of operands in series of floating-point operations. This violates the ISO C and C++ language standard by ! possibly changing computation result. NOTE: re-ordering may ! change the sign of zero as well as ignore NaNs and inhibit or ! create underflow or overflow (and thus cannot be used on code that ! relies on rounding behavior like `(x + 2**52) - 2**52'. May also ! reorder floating-point comparisons and thus may not be used when ! ordered comparisons are required. This option requires that both ! `-fno-signed-zeros' and `-fno-trapping-math' be in effect. ! Moreover, it doesn't make much sense with `-frounding-math'. For Fortran the option is automatically enabled when both ! `-fno-signed-zeros' and `-fno-trapping-math' are in effect. ! The default is `-fno-associative-math'. - `-freciprocal-math' Allow the reciprocal of a value to be used instead of dividing by ! the value if this enables optimizations. For example `x / y' can ! be replaced with `x * (1/y)', which is useful if `(1/y)' is ! subject to common subexpression elimination. Note that this loses precision and increases the number of flops operating on the value. ! The default is `-fno-reciprocal-math'. ! `-ffinite-math-only' Allow optimizations for floating-point arithmetic that assume that arguments and results are not NaNs or +-Infs. ! This option is not turned on by any `-O' option since it can ! result in incorrect output for programs that depend on an exact implementation of IEEE or ISO rules/specifications for math ! functions. It may, however, yield faster code for programs that do not require the guarantees of these specifications. ! The default is `-fno-finite-math-only'. ! `-fno-signed-zeros' Allow optimizations for floating-point arithmetic that ignore the signedness of zero. IEEE arithmetic specifies the behavior of distinct +0.0 and -0.0 values, which then prohibits simplification of expressions such as x+0.0 or 0.0*x (even with ! `-ffinite-math-only'). This option implies that the sign of a ! zero result isn't significant. ! The default is `-fsigned-zeros'. ! `-fno-trapping-math' Compile code assuming that floating-point operations cannot ! generate user-visible traps. These traps include division by ! zero, overflow, underflow, inexact result and invalid operation. ! This option requires that `-fno-signaling-nans' be in effect. ! Setting this option may allow faster code if one relies on ! "non-stop" IEEE arithmetic, for example. ! This option should never be turned on by any `-O' option since it ! can result in incorrect output for programs that depend on an ! exact implementation of IEEE or ISO rules/specifications for math functions. ! The default is `-ftrapping-math'. ! `-frounding-math' Disable transformations and optimizations that assume default floating-point rounding behavior. This is round-to-zero for all ! floating point to integer conversions, and round-to-nearest for ! all other arithmetic truncations. This option should be specified ! for programs that change the FP rounding mode dynamically, or that ! may be executed with a non-default rounding mode. This option ! disables constant folding of floating-point expressions at compile ! time (which may be affected by rounding mode) and arithmetic transformations that are unsafe in the presence of sign-dependent rounding modes. ! The default is `-fno-rounding-math'. This option is experimental and does not currently guarantee to disable all GCC optimizations that are affected by rounding mode. Future versions of GCC may provide finer control of this setting ! using C99's `FENV_ACCESS' pragma. This command-line option will ! be used to specify the default state for `FENV_ACCESS'. ! `-fsignaling-nans' Compile code assuming that IEEE signaling NaNs may generate user-visible traps during floating-point operations. Setting this option disables optimizations that may change the number of exceptions visible with signaling NaNs. This option implies ! `-ftrapping-math'. ! This option causes the preprocessor macro `__SUPPORT_SNAN__' to be defined. ! The default is `-fno-signaling-nans'. This option is experimental and does not currently guarantee to disable all GCC optimizations that affect signaling NaN behavior. ! `-fsingle-precision-constant' Treat floating-point constants as single precision instead of implicitly converting them to double-precision constants. ! `-fcx-limited-range' When enabled, this option states that a range reduction step is not needed when performing complex division. Also, there is no ! checking whether the result of a complex multiplication or ! division is `NaN + I*NaN', with an attempt to rescue the situation ! in that case. The default is `-fno-cx-limited-range', but is ! enabled by `-ffast-math'. This option controls the default setting of the ISO C99 ! `CX_LIMITED_RANGE' pragma. Nevertheless, the option applies to ! all languages. ! `-fcx-fortran-rules' Complex multiplication and division follow Fortran rules. Range reduction is done as part of complex division, but there is no ! checking whether the result of a complex multiplication or ! division is `NaN + I*NaN', with an attempt to rescue the situation ! in that case. ! ! The default is `-fno-cx-fortran-rules'. The following options control optimizations that may improve ! performance, but are not enabled by any `-O' options. This section includes experimental options that may produce broken code. ! `-fbranch-probabilities' ! After running a program compiled with `-fprofile-arcs' (*note ! Options for Debugging Your Program or `gcc': Debugging Options.), ! you can compile it a second time using `-fbranch-probabilities', ! to improve optimizations based on the number of times each branch ! was taken. When a program compiled with `-fprofile-arcs' exits, ! it saves arc execution counts to a file called `SOURCENAME.gcda' ! for each source file. The information in this data file is very dependent on the structure of the generated code, so you must use the same source code and the same optimization options for both compilations. ! With `-fbranch-probabilities', GCC puts a `REG_BR_PROB' note on ! each `JUMP_INSN' and `CALL_INSN'. These can be used to improve optimization. Currently, they are only used in one place: in ! `reorg.c', instead of guessing which path a branch is most likely ! to take, the `REG_BR_PROB' values are used to exactly determine which path is taken more often. ! `-fprofile-values' ! If combined with `-fprofile-arcs', it adds code so that some data about values of expressions in the program is gathered. ! With `-fbranch-probabilities', it reads back the data gathered ! from profiling values of expressions for usage in optimizations. ! Enabled with `-fprofile-generate' and `-fprofile-use'. ! `-fvpt' ! If combined with `-fprofile-arcs', this option instructs the compiler to add code to gather information about values of expressions. ! With `-fbranch-probabilities', it reads back the data gathered and actually performs the optimizations based on them. Currently the optimizations include specialization of division operations using the knowledge about the value of the denominator. ! `-frename-registers' Attempt to avoid false dependencies in scheduled code by making use of registers left over after register allocation. This optimization most benefits processors with lots of registers. --- 7680,8006 ---- represent the comparison operation before register allocation is complete. ! Enabled at levels '-O', '-O2', '-O3', '-Os'. ! '-fuse-ld=bfd' ! Use the 'bfd' linker instead of the default linker. ! '-fuse-ld=gold' ! Use the 'gold' linker instead of the default linker. ! '-fcprop-registers' After register allocation and post-register allocation instruction splitting, perform a copy-propagation pass to try to reduce scheduling dependencies and occasionally eliminate the copy. !

By default, GCC uses the current directory as PATH, thus the profile data file appears in the same directory as the object file. ! '-fprofile-generate' ! '-fprofile-generate=PATH' !

'-ftree-vectorize', 'ftree-loop-distribute-patterns' By default, GCC emits an error message if the feedback profiles do ! not match the source code.

'ipa-cp-value-list-size' is the maximum number of values and types it stores per one formal parameter of a function. ! 'lto-partitions' Specify desired number of partitions produced during WHOPR compilation. The number of partitions should exceed the number of CPUs used for compilation. The default value is 32. ! 'lto-minpartition' Size of minimal partition for WHOPR (in estimated ! instructions). This prevents expenses of splitting very small ! programs into too many partitions. ! 'cxx-max-namespaces-for-diagnostic-help' The maximum number of namespaces to consult for suggestions when C++ name lookup fails for an identifier. The default is 1000. ! 'sink-frequency-threshold' The maximum relative execution frequency (in percents) of the ! target block relative to a statement's original block to allow ! statement sinking of a statement. Larger numbers result in ! more aggressive statement sinking. The default value is 75. ! A small positive adjustment is applied for statements with ! memory operands as those are even more profitable so sink. ! 'max-stores-to-sink' The maximum number of conditional stores paires that can be ! sunk. Set to 0 if either vectorization ('-ftree-vectorize') ! or if-conversion ('-ftree-loop-if-convert') is disabled. The default is 2. ! 'allow-load-data-races' ! Allow optimizers to introduce new data races on loads. Set to ! 1 to allow, otherwise to 0. This option is enabled by default ! unless implicitly set by the '-fmemory-model=' option. ! 'allow-store-data-races' Allow optimizers to introduce new data races on stores. Set to 1 to allow, otherwise to 0.

'-fmemory-model=' option. ! 'case-values-threshold' The smallest number of different values for which it is best ! to use a jump-table instead of a tree of conditional branches. ! If the value is 0, use the default for the machine. The ! default is 0. ! 'tree-reassoc-width' Set the maximum number of instructions executed in parallel in ! reassociated tree. This parameter overrides target dependent heuristics used by default if has non zero value. ! 'sched-pressure-algorithm' Choose between the two available implementations of ! '-fsched-pressure'. Algorithm 1 is the original implementation and is the more likely to prevent instructions from being reordered. Algorithm 2 was designed to be a compromise between the relatively conservative approach taken ! by algorithm 1 and the rather aggressive approach taken by the ! default scheduler. It relies more heavily on having a regular ! register file and accurate register pressure classes. See ! 'haifa-sched.c' in the GCC sources for more details. The default choice depends on the target. ! 'max-slsr-cand-scan' Set the maximum number of existing candidates that will be considered when seeking a basis for a new straight-line strength reduction candidate.

The filename may be absolute or it may be relative to GCC's current directory. ! `-x c' ! `-x c++' ! `-x objective-c' ! `-x assembler-with-cpp' Specify the source language: C, C++, Objective-C, or assembly. ! This has nothing to do with standards conformance or extensions; ! it merely selects which base syntax to expect. If you give none ! of these options, cpp will deduce the language from the extension ! of the source file: `.c', `.cc', `.m', or `.S'. Some other common extensions for C++ and assembly are also recognized. If cpp does not recognize the extension, it will treat the file as C; this is the most generic mode. ! _Note:_ Previous versions of cpp accepted a `-lang' option which selected both the language and the standards conformance level. ! This option has been removed, because it conflicts with the `-l' option. ! `-std=STANDARD' ! `-ansi' Specify the standard to which the code should conform. Currently CPP knows about C and C++ standards; others may be added in the future. STANDARD may be one of: ! `c90' ! `c89' ! `iso9899:1990' ! The ISO C standard from 1990. `c90' is the customary shorthand for this version of the standard. ! The `-ansi' option is equivalent to `-std=c90'. ! `iso9899:199409' The 1990 C standard, as amended in 1994. ! `iso9899:1999' ! `c99' ! `iso9899:199x' ! `c9x' The revised ISO C standard, published in December 1999. Before publication, this was known as C9X. ! `iso9899:2011' ! `c11' ! `c1x' The revised ISO C standard, published in December 2011. Before publication, this was known as C1X. ! `gnu90' ! `gnu89' The 1990 C standard plus GNU extensions. This is the default. ! `gnu99' ! `gnu9x' The 1999 C standard plus GNU extensions. ! `gnu11' ! `gnu1x' The 2011 C standard plus GNU extensions. ! `c++98' The 1998 ISO C++ standard plus amendments. ! `gnu++98' ! The same as `-std=c++98' plus GNU extensions. This is the default for C++ code. ! `-I-' ! Split the include path. Any directories specified with `-I' ! options before `-I-' are searched only for headers requested with ! `#include "FILE"'; they are not searched for `#include '. ! If additional directories are specified with `-I' options after ! the `-I-', those directories are searched for all `#include' directives. ! In addition, `-I-' inhibits the use of the directory of the current ! file directory as the first search directory for `#include "FILE"'. This option has been deprecated. ! `-nostdinc' Do not search the standard system directories for header files. ! Only the directories you have specified with `-I' options (and the directory of the current file, if appropriate) are searched. ! `-nostdinc++' Do not search for header files in the C++-specific standard directories, but do still search the other standard directories. (This option is used when building the C++ library.) ! `-include FILE' ! Process FILE as if `#include "file"' appeared as the first line of ! the primary source file. However, the first directory searched ! for FILE is the preprocessor's working directory _instead of_ the directory containing the main source file. If not found there, it ! is searched for in the remainder of the `#include "..."' search chain as normal. ! If multiple `-include' options are given, the files are included ! in the order they appear on the command line. ! `-imacros FILE' ! Exactly like `-include', except that any output produced by scanning FILE is thrown away. Macros it defines remain defined. This allows you to acquire all the macros from a header without also processing its declarations. ! All files specified by `-imacros' are processed before all files ! specified by `-include'. ! `-idirafter DIR' Search DIR for header files, but do it _after_ all directories ! specified with `-I' and the standard system directories have been exhausted. DIR is treated as a system include directory. If DIR ! begins with `=', then the `=' will be replaced by the sysroot ! prefix; see `--sysroot' and `-isysroot'. ! `-iprefix PREFIX' ! Specify PREFIX as the prefix for subsequent `-iwithprefix' ! options. If the prefix represents a directory, you should include ! the final `/'. ! `-iwithprefix DIR' ! `-iwithprefixbefore DIR' ! Append DIR to the prefix specified previously with `-iprefix', and add the resulting directory to the include search path. ! `-iwithprefixbefore' puts it in the same place `-I' would; ! `-iwithprefix' puts it where `-idirafter' would. ! `-isysroot DIR' ! This option is like the `--sysroot' option, but applies only to header files (except for Darwin targets, where it applies to both ! header files and libraries). See the `--sysroot' option for more information. ! `-imultilib DIR' Use DIR as a subdirectory of the directory containing target-specific C++ headers. ! `-isystem DIR' Search DIR for header files, after all directories specified by ! `-I' but before the standard system directories. Mark it as a system directory, so that it gets the same special treatment as is applied to the standard system directories. If DIR begins with ! `=', then the `=' will be replaced by the sysroot prefix; see ! `--sysroot' and `-isysroot'. ! `-iquote DIR' ! Search DIR only for header files requested with `#include "FILE"'; ! they are not searched for `#include ', before all ! directories specified by `-I' and before the standard system ! directories. If DIR begins with `=', then the `=' will be replaced ! by the sysroot prefix; see `--sysroot' and `-isysroot'. ! `-fdirectives-only' When preprocessing, handle directives, but do not expand macros. ! The option's behavior depends on the `-E' and `-fpreprocessed' options. ! With `-E', preprocessing is limited to the handling of directives ! such as `#define', `#ifdef', and `#error'. Other preprocessor ! operations, such as macro expansion and trigraph conversion are ! not performed. In addition, the `-dD' option is implicitly ! enabled. ! With `-fpreprocessed', predefinition of command line and most ! builtin macros is disabled. Macros such as `__LINE__', which are contextually dependent, are handled normally. This enables ! compilation of files previously preprocessed with `-E -fdirectives-only'. ! With both `-E' and `-fpreprocessed', the rules for ! `-fpreprocessed' take precedence. This enables full preprocessing ! of files previously preprocessed with `-E -fdirectives-only'. ! `-fdollars-in-identifiers' ! Accept `$' in identifiers. ! `-fextended-identifiers' Accept universal character names in identifiers. This option is experimental; in a future version of GCC, it will be enabled by default for C99 and C++. ! `-fno-canonical-system-headers' When preprocessing, do not shorten system header paths with canonicalization. ! `-fpreprocessed' Indicate to the preprocessor that the input file has already been preprocessed. This suppresses things like macro expansion, trigraph conversion, escaped newline splicing, and processing of most directives. The preprocessor still recognizes and removes ! comments, so that you can pass a file preprocessed with `-C' to ! the compiler without problems. In this mode the integrated preprocessor is little more than a tokenizer for the front ends. ! `-fpreprocessed' is implicit if the input file has one of the ! extensions `.i', `.ii' or `.mi'. These are the extensions that ! GCC uses for preprocessed files created by `-save-temps'. ! `-ftabstop=WIDTH' Set the distance between tab stops. This helps the preprocessor report correct column numbers in warnings or errors, even if tabs appear on the line. If the value is less than 1 or greater than 100, the option is ignored. The default is 8. ! `-fdebug-cpp' ! This option is only useful for debugging GCC. When used with ! `-E', dumps debugging information about location maps. Every ! token in the output is preceded by the dump of the map its location ! belongs to. The dump of the map holding the location of a token ! would be: ! {`P':`/file/path';`F':`/includer/path';`L':LINE_NUM;`C':COL_NUM;`S':SYSTEM_HEADER_P;`M':MAP_ADDRESS;`E':MACRO_EXPANSION_P,`loc':LOCATION} ! When used without `-E', this option has no effect. ! `-ftrack-macro-expansion[=LEVEL]' ! Track locations of tokens across macro expansions. This allows the compiler to emit diagnostic about the current macro expansion stack ! when a compilation error occurs in a macro expansion. Using this ! option makes the preprocessor and the compiler consume more ! memory. The LEVEL parameter can be used to choose the level of ! precision of token location tracking thus decreasing the memory ! consumption if necessary. Value `0' of LEVEL de-activates this ! option just as if no `-ftrack-macro-expansion' was present on the ! command line. Value `1' tracks tokens locations in a degraded mode ! for the sake of minimal memory overhead. In this mode all tokens ! resulting from the expansion of an argument of a function-like ! macro have the same location. Value `2' tracks tokens locations ! completely. This value is the most memory hungry. When this ! option is given no argument, the default parameter value is `2'. Note that -ftrack-macro-expansion=2 is activated by default. ! `-fexec-charset=CHARSET' Set the execution character set, used for string and character constants. The default is UTF-8. CHARSET can be any encoding ! supported by the system's `iconv' library routine. ! `-fwide-exec-charset=CHARSET' Set the wide execution character set, used for wide string and character constants. The default is UTF-32 or UTF-16, whichever ! corresponds to the width of `wchar_t'. As with `-fexec-charset', ! CHARSET can be any encoding supported by the system's `iconv' library routine; however, you will have problems with encodings ! that do not fit exactly in `wchar_t'. ! `-finput-charset=CHARSET' Set the input character set, used for translation from the ! character set of the input file to the source character set used ! by GCC. If the locale does not specify, or GCC cannot get this information from the locale, the default is UTF-8. This can be overridden by either the locale or this command line option. Currently the command line option takes precedence if there's a conflict. CHARSET can be any encoding supported by the system's ! `iconv' library routine. ! `-fworking-directory' Enable generation of linemarkers in the preprocessor output that will let the compiler know the current working directory at the time of preprocessing. When this option is enabled, the preprocessor will emit, after the initial linemarker, a second linemarker with the current working directory followed by two slashes. GCC will use this directory, when it's present in the ! preprocessed input, as the directory emitted as the current ! working directory in some debugging information formats. This ! option is implicitly enabled if debugging information is enabled, ! but this can be inhibited with the negated form ! `-fno-working-directory'. If the `-P' flag is present in the ! command line, this option has no effect, since no `#line' ! directives are emitted whatsoever. ! `-fno-show-column' Do not print column numbers in diagnostics. This may be necessary if diagnostics are being scanned by a program that does not ! understand the column numbers, such as `dejagnu'. ! `-A PREDICATE=ANSWER' Make an assertion with the predicate PREDICATE and answer ANSWER. ! This form is preferred to the older form `-A PREDICATE(ANSWER)', which is still supported, because it does not use shell special characters. ! `-A -PREDICATE=ANSWER' Cancel an assertion with the predicate PREDICATE and answer ANSWER. ! `-dCHARS' ! CHARS is a sequence of one or more of the following characters, ! and must not be preceded by a space. Other characters are ! interpreted by the compiler proper, or reserved for future ! versions of GCC, and so are silently ignored. If you specify ! characters whose behavior conflicts, the result is undefined. ! `M' ! Instead of the normal output, generate a list of `#define' directives for all the macros defined during the execution of ! the preprocessor, including predefined macros. This gives ! you a way of finding out what is predefined in your version ! of the preprocessor. Assuming you have no file `foo.h', the ! command touch foo.h; cpp -dM foo.h will show all the predefined macros. ! If you use `-dM' without the `-E' option, `-dM' is ! interpreted as a synonym for `-fdump-rtl-mach'. *Note ! Debugging Options: (gcc)Debugging Options. ! `D' ! Like `M' except in two respects: it does _not_ include the ! predefined macros, and it outputs _both_ the `#define' directives and the result of preprocessing. Both kinds of output go to the standard output file. ! `N' ! Like `D', but emit only the macro names, not their expansions. ! `I' ! Output `#include' directives in addition to the result of preprocessing. ! `U' ! Like `D' except that only macros that are expanded, or whose definedness is tested in preprocessor directives, are output; the output is delayed until the use or test of the macro; and ! `#undef' directives are also output for macros tested but undefined at the time. ! `-P' Inhibit generation of linemarkers in the output from the preprocessor. This might be useful when running the preprocessor on something that is not C code, and will be sent to a program which might be confused by the linemarkers. ! `-C' Do not discard comments. All comments are passed through to the ! output file, except for comments in processed directives, which ! are deleted along with the directive. ! You should be prepared for side effects when using `-C'; it causes the preprocessor to treat comments as tokens in their own right. For example, comments appearing at the start of what would be a directive line have the effect of turning that line into an ordinary source line, since the first token on the line is no ! longer a `#'. ! `-CC' Do not discard comments, including during macro expansion. This is ! like `-C', except that comments contained within macros are also passed through to the output file where the macro is expanded. ! In addition to the side-effects of the `-C' option, the `-CC' ! option causes all C++-style comments inside a macro to be ! converted to C-style comments. This is to prevent later use of ! that macro from inadvertently commenting out the remainder of the ! source line. ! The `-CC' option is generally used to support lint comments. ! `-traditional-cpp' Try to imitate the behavior of old-fashioned C preprocessors, as opposed to ISO C preprocessors. ! `-trigraphs' Process trigraph sequences. These are three-character sequences, ! all starting with `??', that are defined by ISO C to stand for ! single characters. For example, `??/' stands for `\', so `'??/n'' is a character constant for a newline. By default, GCC ignores trigraphs, but in standard-conforming modes it converts them. See ! the `-std' and `-ansi' options. The nine trigraphs and their replacements are Trigraph: ??( ??) ??< ??> ??= ??/ ??' ??! ??- Replacement: [ ] { } # \ ^ | ~ ! `-remap' Enable special code to work around file systems which only permit very short file names, such as MS-DOS. ! `--help' ! `--target-help' Print text describing all the command line options instead of preprocessing anything. ! `-v' Verbose mode. Print out GNU CPP's version number at the beginning of execution, and report the final form of the include path. ! `-H' Print the name of each header file used, in addition to other normal activities. Each name is indented to show how deep in the ! `#include' stack it is. Precompiled header files are also ! printed, even if they are found to be invalid; an invalid ! precompiled header file is printed with `...x' and a valid one ! with `...!' . ! `-version' ! `--version' Print out GNU CPP's version number. With one dash, proceed to preprocess as normal. With two dashes, exit immediately. --- 9279,9696 ---- used to create it because those files are not consulted when a precompiled header is used. ! '-fpch-preprocess' This option allows use of a precompiled header (*note Precompiled ! Headers::) together with '-E'. It inserts a special '#pragma', ! '#pragma GCC pch_preprocess "FILENAME"' in the output to mark the place where the precompiled header was found, and its FILENAME. ! When '-fpreprocessed' is in use, GCC recognizes this '#pragma' and loads the PCH. This option is off by default, because the resulting preprocessed output is only really suitable as input to GCC. It is switched on ! by '-save-temps'. ! You should not write this '#pragma' in your own code, but it is safe to edit the filename if the PCH file is available in a different location. The filename may be absolute or it may be relative to GCC's current directory. ! '-x c' ! '-x c++' ! '-x objective-c' ! '-x assembler-with-cpp' Specify the source language: C, C++, Objective-C, or assembly. ! This has nothing to do with standards conformance or extensions; it ! merely selects which base syntax to expect. If you give none of ! these options, cpp will deduce the language from the extension of ! the source file: '.c', '.cc', '.m', or '.S'. Some other common extensions for C++ and assembly are also recognized. If cpp does not recognize the extension, it will treat the file as C; this is the most generic mode. ! _Note:_ Previous versions of cpp accepted a '-lang' option which selected both the language and the standards conformance level. ! This option has been removed, because it conflicts with the '-l' option. ! '-std=STANDARD' ! '-ansi' Specify the standard to which the code should conform. Currently CPP knows about C and C++ standards; others may be added in the future. STANDARD may be one of: ! 'c90' ! 'c89' ! 'iso9899:1990' ! The ISO C standard from 1990. 'c90' is the customary shorthand for this version of the standard. ! The '-ansi' option is equivalent to '-std=c90'. ! 'iso9899:199409' The 1990 C standard, as amended in 1994. ! 'iso9899:1999' ! 'c99' ! 'iso9899:199x' ! 'c9x' The revised ISO C standard, published in December 1999. Before publication, this was known as C9X. ! 'iso9899:2011' ! 'c11' ! 'c1x' The revised ISO C standard, published in December 2011. Before publication, this was known as C1X. ! 'gnu90' ! 'gnu89' The 1990 C standard plus GNU extensions. This is the default. ! 'gnu99' ! 'gnu9x' The 1999 C standard plus GNU extensions. ! 'gnu11' ! 'gnu1x' The 2011 C standard plus GNU extensions. ! 'c++98' The 1998 ISO C++ standard plus amendments. ! 'gnu++98' ! The same as '-std=c++98' plus GNU extensions. This is the default for C++ code. ! '-I-' ! Split the include path. Any directories specified with '-I' ! options before '-I-' are searched only for headers requested with ! '#include "FILE"'; they are not searched for '#include '. If ! additional directories are specified with '-I' options after the ! '-I-', those directories are searched for all '#include' directives. ! In addition, '-I-' inhibits the use of the directory of the current ! file directory as the first search directory for '#include "FILE"'. This option has been deprecated. ! '-nostdinc' Do not search the standard system directories for header files. ! Only the directories you have specified with '-I' options (and the directory of the current file, if appropriate) are searched. ! '-nostdinc++' Do not search for header files in the C++-specific standard directories, but do still search the other standard directories. (This option is used when building the C++ library.) ! '-include FILE' ! Process FILE as if '#include "file"' appeared as the first line of ! the primary source file. However, the first directory searched for ! FILE is the preprocessor's working directory _instead of_ the directory containing the main source file. If not found there, it ! is searched for in the remainder of the '#include "..."' search chain as normal. ! If multiple '-include' options are given, the files are included in ! the order they appear on the command line. ! '-imacros FILE' ! Exactly like '-include', except that any output produced by scanning FILE is thrown away. Macros it defines remain defined. This allows you to acquire all the macros from a header without also processing its declarations. ! All files specified by '-imacros' are processed before all files ! specified by '-include'. ! '-idirafter DIR' Search DIR for header files, but do it _after_ all directories ! specified with '-I' and the standard system directories have been exhausted. DIR is treated as a system include directory. If DIR ! begins with '=', then the '=' will be replaced by the sysroot ! prefix; see '--sysroot' and '-isysroot'. ! '-iprefix PREFIX' ! Specify PREFIX as the prefix for subsequent '-iwithprefix' options. ! If the prefix represents a directory, you should include the final ! '/'. ! '-iwithprefix DIR' ! '-iwithprefixbefore DIR' ! Append DIR to the prefix specified previously with '-iprefix', and add the resulting directory to the include search path. ! '-iwithprefixbefore' puts it in the same place '-I' would; ! '-iwithprefix' puts it where '-idirafter' would. ! '-isysroot DIR' ! This option is like the '--sysroot' option, but applies only to header files (except for Darwin targets, where it applies to both ! header files and libraries). See the '--sysroot' option for more information. ! '-imultilib DIR' Use DIR as a subdirectory of the directory containing target-specific C++ headers. ! '-isystem DIR' Search DIR for header files, after all directories specified by ! '-I' but before the standard system directories. Mark it as a system directory, so that it gets the same special treatment as is applied to the standard system directories. If DIR begins with ! '=', then the '=' will be replaced by the sysroot prefix; see ! '--sysroot' and '-isysroot'. ! '-iquote DIR' ! Search DIR only for header files requested with '#include "FILE"'; ! they are not searched for '#include ', before all directories ! specified by '-I' and before the standard system directories. If ! DIR begins with '=', then the '=' will be replaced by the sysroot ! prefix; see '--sysroot' and '-isysroot'. ! '-fdirectives-only' When preprocessing, handle directives, but do not expand macros. !

They are meaningless if the compiler is not doing a link step. ! `OBJECT-FILE-NAME' A file name that does not end in a special recognized suffix is considered to name an object file or library. (Object files are distinguished from libraries by the linker according to the file contents.) If linking is done, these object files are used as input to the linker. ! `-c' ! `-S' ! `-E' If any of these options is used, then the linker is not run, and object file names should not be used as arguments. *Note Overall Options::. ! `-lLIBRARY' ! `-l LIBRARY' Search the library named LIBRARY when linking. (The second alternative with the library as a separate argument is only for POSIX compliance and is not recommended.) It makes a difference where in the command you write this option; ! the linker searches and processes libraries and object files in ! the order they are specified. Thus, `foo.o -lz bar.o' searches ! library `z' after file `foo.o' but before `bar.o'. If `bar.o' ! refers to functions in `z', those functions may not be loaded. The linker searches a standard list of directories for the library, ! which is actually a file named `libLIBRARY.a'. The linker then uses this file as if it had been specified precisely by name. The directories searched include several standard system ! directories plus any that you specify with `-L'. Normally the files found this way are library files--archive files ! whose members are object files. The linker handles an archive ! file by scanning through it for members which define symbols that ! have so far been referenced but not defined. But if the file that ! is found is an ordinary object file, it is linked in the usual ! fashion. The only difference between using an `-l' option and ! specifying a file name is that `-l' surrounds LIBRARY with `lib' ! and `.a' and searches several directories. ! `-lobjc' ! You need this special case of the `-l' option in order to link an Objective-C or Objective-C++ program. ! `-nostartfiles' Do not use the standard system startup files when linking. The ! standard system libraries are used normally, unless `-nostdlib' or ! `-nodefaultlibs' is used. ! `-nodefaultlibs' Do not use the standard system libraries when linking. Only the libraries you specify are passed to the linker, and options specifying linkage of the system libraries, such as ! `-static-libgcc' or `-shared-libgcc', are ignored. The standard ! startup files are used normally, unless `-nostartfiles' is used. ! The compiler may generate calls to `memcmp', `memset', `memcpy' ! and `memmove'. These entries are usually resolved by entries in ! libc. These entry points should be supplied through some other ! mechanism when this option is specified. ! `-nostdlib' Do not use the standard system startup files or libraries when linking. No startup files and only the libraries you specify are passed to the linker, and options specifying linkage of the system ! libraries, such as `-static-libgcc' or `-shared-libgcc', are ignored. ! The compiler may generate calls to `memcmp', `memset', `memcpy' ! and `memmove'. These entries are usually resolved by entries in ! libc. These entry points should be supplied through some other ! mechanism when this option is specified. ! One of the standard libraries bypassed by `-nostdlib' and ! `-nodefaultlibs' is `libgcc.a', a library of internal subroutines which GCC uses to overcome shortcomings of particular machines, or special needs for some languages. (*Note Interfacing to GCC ! Output: (gccint)Interface, for more discussion of `libgcc.a'.) In ! most cases, you need `libgcc.a' even when you want to avoid other ! standard libraries. In other words, when you specify `-nostdlib' ! or `-nodefaultlibs' you should usually specify `-lgcc' as well. This ensures that you have no unresolved references to internal GCC ! library subroutines. (An example of such an internal subroutine ! is `__main', used to ensure C++ constructors are called; *note ! `collect2': (gccint)Collect2.) ! `-pie' Produce a position independent executable on targets that support ! it. For predictable results, you must also specify the same set ! of options used for compilation (`-fpie', `-fPIE', or model suboptions) when you specify this linker option. ! `-rdynamic' ! Pass the flag `-export-dynamic' to the ELF linker, on targets that ! support it. This instructs the linker to add all symbols, not only ! used ones, to the dynamic symbol table. This option is needed for ! some uses of `dlopen' or to allow obtaining backtraces from within a program. ! `-s' Remove all symbol table and relocation information from the executable. ! `-static' !

For predictable results, you must also specify the same ! set of options used for compilation (`-fpic', `-fPIC', or model ! suboptions) when you specify this linker option.(1) ! `-shared-libgcc' ! `-static-libgcc' ! On systems that provide `libgcc' as a shared library, these options force the use of either the shared or static version, respectively. ! If no shared version of `libgcc' was built when the compiler was configured, these options have no effect. There are several situations in which an application should use the ! shared `libgcc' instead of the static version. The most common of these is when the application wishes to throw and catch exceptions across different shared libraries. In that case, each of the libraries as well as the application itself should use the shared ! `libgcc'. Therefore, the G++ and GCJ drivers automatically add ! `-shared-libgcc' whenever you build a shared library or a main ! executable, because C++ and Java programs typically use ! exceptions, so this is the right thing to do. ! If, instead, you use the GCC driver to create shared libraries, ! you may find that they are not always linked with the shared ! `libgcc'. If GCC finds, at its configuration time, that you have ! a non-GNU linker or a GNU linker that does not support option ! `--eh-frame-hdr', it links the shared version of `libgcc' into shared libraries by default. Otherwise, it takes advantage of the linker and optimizes away the linking with the shared version of ! `libgcc', linking with the static version of libgcc by default. This allows exceptions to propagate through such shared libraries, without incurring relocation costs at library load time. However, if a library or main executable is supposed to throw or catch exceptions, you must link it using the G++ or GCJ driver, as appropriate for the languages used in the program, or using the ! option `-shared-libgcc', such that it is linked with the shared ! `libgcc'. ! `-static-libasan' ! When the `-fsanitize=address' option is used to link a program, ! the GCC driver automatically links against `libasan'. If ! `libasan' is available as a shared library, and the `-static' ! option is not used, then this links against the shared version of ! `libasan'. The `-static-libasan' option directs the GCC driver to ! link `libasan' statically, without necessarily linking other ! libraries statically. ! `-static-libtsan' ! When the `-fsanitize=thread' option is used to link a program, the ! GCC driver automatically links against `libtsan'. If `libtsan' is ! available as a shared library, and the `-static' option is not ! used, then this links against the shared version of `libtsan'. ! The `-static-libtsan' option directs the GCC driver to link ! `libtsan' statically, without necessarily linking other libraries ! statically. ! `-static-libstdc++' ! When the `g++' program is used to link a C++ program, it normally ! automatically links against `libstdc++'. If `libstdc++' is ! available as a shared library, and the `-static' option is not ! used, then this links against the shared version of `libstdc++'. That is normally fine. However, it is sometimes useful to freeze ! the version of `libstdc++' used by the program without going all ! the way to a fully static link. The `-static-libstdc++' option ! directs the `g++' driver to link `libstdc++' statically, without necessarily linking other libraries statically. ! `-symbolic' Bind references to global symbols when building a shared object. ! Warn about any unresolved references (unless overridden by the ! link editor option `-Xlinker -z -Xlinker defs'). Only a few ! systems support this option. ! `-T SCRIPT' Use SCRIPT as the linker script. This option is supported by most systems using the GNU linker. On some targets, such as bare-board ! targets without an operating system, the `-T' option may be required when linking to avoid references to undefined symbols. ! `-Xlinker OPTION' ! Pass OPTION as an option to the linker. You can use this to ! supply system-specific linker options that GCC does not recognize. If you want to pass an option that takes a separate argument, you ! must use `-Xlinker' twice, once for the option and once for the ! argument. For example, to pass `-assert definitions', you must ! write `-Xlinker -assert -Xlinker definitions'. It does not work ! to write `-Xlinker "-assert definitions"', because this passes the entire string as a single argument, which is not what the linker expects. When using the GNU linker, it is usually more convenient to pass ! arguments to linker options using the `OPTION=VALUE' syntax than ! as separate arguments. For example, you can specify `-Xlinker ! -Map=output.map' rather than `-Xlinker -Map -Xlinker output.map'. Other linkers may not support this syntax for command-line options. ! `-Wl,OPTION' ! Pass OPTION as an option to the linker. If OPTION contains ! commas, it is split into multiple options at the commas. You can ! use this syntax to pass an argument to the option. For example, ! `-Wl,-Map,output.map' passes `-Map output.map' to the linker. ! When using the GNU linker, you can also get the same effect with ! `-Wl,-Map=output.map'. ! `-u SYMBOL' ! Pretend the symbol SYMBOL is undefined, to force linking of ! library modules to define it. You can use `-u' multiple times with different symbols to force loading of additional library modules. ! ---------- Footnotes ---------- ! (1) On some systems, `gcc -shared' needs to build supplementary stub ! code for constructors to work. On multi-libbed systems, `gcc -shared' must select the correct support libraries to link against. Failing to supply the correct flags may lead to subtle defects. Supplying them in cases where they are not necessary is innocuous. --- 9724,9955 ---- an executable output file. They are meaningless if the compiler is not doing a link step. ! 'OBJECT-FILE-NAME' A file name that does not end in a special recognized suffix is considered to name an object file or library. (Object files are distinguished from libraries by the linker according to the file contents.) If linking is done, these object files are used as input to the linker. ! '-c' ! '-S' ! '-E' If any of these options is used, then the linker is not run, and object file names should not be used as arguments. *Note Overall Options::. ! '-lLIBRARY' ! '-l LIBRARY' Search the library named LIBRARY when linking. (The second alternative with the library as a separate argument is only for POSIX compliance and is not recommended.) It makes a difference where in the command you write this option; ! the linker searches and processes libraries and object files in the ! order they are specified. Thus, 'foo.o -lz bar.o' searches library ! 'z' after file 'foo.o' but before 'bar.o'. If 'bar.o' refers to ! functions in 'z', those functions may not be loaded. The linker searches a standard list of directories for the library, ! which is actually a file named 'libLIBRARY.a'. The linker then uses this file as if it had been specified precisely by name. The directories searched include several standard system ! directories plus any that you specify with '-L'. Normally the files found this way are library files--archive files ! whose members are object files. The linker handles an archive file ! by scanning through it for members which define symbols that have ! so far been referenced but not defined. But if the file that is ! found is an ordinary object file, it is linked in the usual ! fashion. The only difference between using an '-l' option and ! specifying a file name is that '-l' surrounds LIBRARY with 'lib' ! and '.a' and searches several directories. ! '-lobjc' ! You need this special case of the '-l' option in order to link an Objective-C or Objective-C++ program. ! '-nostartfiles' Do not use the standard system startup files when linking. The ! standard system libraries are used normally, unless '-nostdlib' or ! '-nodefaultlibs' is used. ! '-nodefaultlibs' Do not use the standard system libraries when linking. Only the libraries you specify are passed to the linker, and options specifying linkage of the system libraries, such as ! '-static-libgcc' or '-shared-libgcc', are ignored. The standard ! startup files are used normally, unless '-nostartfiles' is used. ! The compiler may generate calls to 'memcmp', 'memset', 'memcpy' and ! 'memmove'. These entries are usually resolved by entries in libc. ! These entry points should be supplied through some other mechanism ! when this option is specified. ! '-nostdlib' Do not use the standard system startup files or libraries when linking. No startup files and only the libraries you specify are passed to the linker, and options specifying linkage of the system ! libraries, such as '-static-libgcc' or '-shared-libgcc', are ignored. ! The compiler may generate calls to 'memcmp', 'memset', 'memcpy' and ! 'memmove'. These entries are usually resolved by entries in libc. ! These entry points should be supplied through some other mechanism ! when this option is specified. ! One of the standard libraries bypassed by '-nostdlib' and ! '-nodefaultlibs' is 'libgcc.a', a library of internal subroutines which GCC uses to overcome shortcomings of particular machines, or special needs for some languages. (*Note Interfacing to GCC ! Output: (gccint)Interface, for more discussion of 'libgcc.a'.) In ! most cases, you need 'libgcc.a' even when you want to avoid other ! standard libraries. In other words, when you specify '-nostdlib' ! or '-nodefaultlibs' you should usually specify '-lgcc' as well. This ensures that you have no unresolved references to internal GCC ! library subroutines. (An example of such an internal subroutine is ! '__main', used to ensure C++ constructors are called; *note ! 'collect2': (gccint)Collect2.) ! '-pie' Produce a position independent executable on targets that support ! it. For predictable results, you must also specify the same set of ! options used for compilation ('-fpie', '-fPIE', or model suboptions) when you specify this linker option. ! '-rdynamic' !

If that name is not found, or if `-B' is not ! specified, the driver tries two standard prefixes, `/usr/lib/gcc/' ! and `/usr/local/lib/gcc/'. If neither of those results in a file name that is found, the unmodified program name is searched for ! using the directories specified in your `PATH' environment variable. ! The compiler checks to see if the path provided by the `-B' refers to a directory, and if necessary it adds a directory separator character at the end of the path. ! `-B' prefixes that effectively specify directory names also apply to libraries in the linker, because the compiler translates these ! options into `-L' options for the linker.

For example, if the compiler normally searches for headers in ! `/usr/include' and libraries in `/usr/lib', it instead searches ! `DIR/usr/include' and `DIR/usr/lib'. ! If you use both this option and the `-isysroot' option, then the ! `--sysroot' option applies to libraries, but the `-isysroot' ! option applies to header files.

This example renames the spec called `lib' to `old_lib' and then ! overrides the previous definition of `lib' with a new one. The new definition adds in some extra command-line options before including the text of the old definition. "Spec strings" are a list of command-line options to be passed to their corresponding program. In addition, the spec strings can contain ! `%'-prefixed sequences to substitute variable text or to conditionally insert text into the command line. Using these constructs it is possible to generate quite complex command lines. ! Here is a table of all defined `%'-sequences for spec strings. Note that spaces are not generated automatically around the results of expanding these sequences. Therefore you can concatenate them together or combine them with constant text in a single argument. ! `%%' ! Substitute one `%' into the program name or argument. ! `%i' Substitute the name of the input file being processed. ! `%b' ! Substitute the basename of the input file being processed. This ! is the substring up to (and not including) the last period and not including the directory. ! `%B' ! This is the same as `%b', but include the file suffix (text after the last period). ! `%d' ! Marks the argument containing or following the `%d' as a temporary file name, so that that file is deleted if GCC exits successfully. ! Unlike `%g', this contributes no text to the argument. ! `%gSUFFIX' Substitute a file name that has suffix SUFFIX and is chosen once ! per compilation, and mark the argument in the same way as `%d'. ! To reduce exposure to denial-of-service attacks, the file name is ! now chosen in a way that is hard to predict even when previously ! chosen file names are known. For example, `%g.s ... %g.o ... %g.s' ! might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX ! matches the regexp `[.A-Za-z]*' or the special string `%O', which ! is treated exactly as if `%O' had been preprocessed. Previously, ! `%g' was simply substituted with a file name chosen once per ! compilation, without regard to any appended suffix (which was ! therefore treated just like ordinary text), making such attacks ! more likely to succeed. ! `%uSUFFIX' ! Like `%g', but generates a new temporary file name each time it appears instead of once per compilation. ! `%USUFFIX' ! Substitutes the last file name generated with `%uSUFFIX', generating a new one if there is no such last file name. In the ! absence of any `%uSUFFIX', this is just like `%gSUFFIX', except ! they don't share the same suffix _space_, so `%g.s ... %U.s ... %g.s ... %U.s' involves the generation of two distinct file names, ! one for each `%g.s' and another for each `%U.s'. Previously, `%U' was simply substituted with a file name chosen for the previous ! `%u', without regard to any appended suffix. ! `%jSUFFIX' ! Substitutes the name of the `HOST_BIT_BUCKET', if any, and if it is ! writable, and if `-save-temps' is not used; otherwise, substitute ! the name of a temporary file, just like `%u'. This temporary file is not meant for communication between processes, but rather as a junk disposal mechanism. ! `%|SUFFIX' ! `%mSUFFIX' ! Like `%g', except if `-pipe' is in effect. In that case `%|' ! substitutes a single dash and `%m' substitutes nothing at all. These are the two most common ways to instruct a program that it should read from standard input or write to standard output. If ! you need something more elaborate you can use an `%{pipe:`X'}' ! construct: see for example `f/lang-specs.h'. ! `%.SUFFIX' Substitutes .SUFFIX for the suffixes of a matched switch's args ! when it is subsequently output with `%*'. SUFFIX is terminated by the next space or %. ! `%w' ! Marks the argument containing or following the `%w' as the designated output file of this compilation. This puts the argument ! into the sequence of arguments that `%o' substitutes. ! `%o' Substitutes the names of all the output files, with spaces automatically placed around them. You should write spaces around ! the `%o' as well or the results are undefined. `%o' is for use in the specs for running the linker. Input files whose names have no recognized suffix are not compiled at all, but they are included among the output files, so they are linked. ! `%O' ! Substitutes the suffix for object files. Note that this is ! handled specially when it immediately follows `%g, %u, or %U', ! because of the need for those to form complete file names. The ! handling is such that `%O' is treated exactly as if it had already ! been substituted, except that `%g, %u, and %U' do not currently ! support additional SUFFIX characters following `%O' as they do ! following, for example, `.o'. ! `%p' Substitutes the standard macro predefinitions for the current ! target machine. Use this when running `cpp'. ! `%P' ! Like `%p', but puts `__' before and after the name of each ! predefined macro, except for macros that start with `__' or with ! `_L', where L is an uppercase letter. This is for ISO C. ! `%I' ! Substitute any of `-iprefix' (made from `GCC_EXEC_PREFIX'), ! `-isysroot' (made from `TARGET_SYSTEM_ROOT'), `-isystem' (made ! from `COMPILER_PATH' and `-B' options) and `-imultilib' as ! necessary. ! `%s' Current argument is the name of a library or startup file of some sort. Search for that file in a standard list of directories and substitute the full name found. The current working directory is included in the list of directories scanned. ! `%T' Current argument is the name of a linker script. Search for that ! file in the current list of directories to scan for libraries. If ! the file is located insert a `--script' option into the command line followed by the full path name found. If the file is not found then generate an error message. Note: the current working directory is not searched. ! `%eSTR' Print STR as an error message. STR is terminated by a newline. Use this when inconsistent options are detected. ! `%(NAME)' Substitute the contents of spec string NAME at this point. ! `%x{OPTION}' ! Accumulate an option for `%X'. ! `%X' ! Output the accumulated linker options specified by `-Wl' or a `%x' spec string. ! `%Y' ! Output the accumulated assembler options specified by `-Wa'. ! `%Z' ! Output the accumulated preprocessor options specified by `-Wp'. ! `%a' ! Process the `asm' spec. This is used to compute the switches to ! be passed to the assembler. ! `%A' ! Process the `asm_final' spec. This is a spec string for passing switches to an assembler post-processor, if such a program is needed. ! `%l' ! Process the `link' spec. This is the spec for computing the command line passed to the linker. Typically it makes use of the ! `%L %G %S %D and %E' sequences. ! `%D' ! Dump out a `-L' option for each directory that GCC believes might contain startup files. If the target supports multilibs then the current multilib directory is prepended to each of these paths. ! `%L' ! Process the `lib' spec. This is a spec string for deciding which libraries are included on the command line to the linker. ! `%G' ! Process the `libgcc' spec. This is a spec string for deciding which GCC support library is included on the command line to the linker. ! `%S' ! Process the `startfile' spec. This is a spec for deciding which object files are the first ones passed to the linker. Typically ! this might be a file named `crt0.o'. ! `%E' ! Process the `endfile' spec. This is a spec string that specifies the last object files that are passed to the linker. ! `%C' ! Process the `cpp' spec. This is used to construct the arguments ! to be passed to the C preprocessor. ! `%1' ! Process the `cc1' spec. This is used to construct the options to ! be passed to the actual C compiler (`cc1'). ! `%2' ! Process the `cc1plus' spec. This is used to construct the options ! to be passed to the actual C++ compiler (`cc1plus'). ! `%*' ! Substitute the variable part of a matched option. See below. ! Note that each comma in the substituted string is replaced by a ! single space. ! `%<`S'' ! Remove all occurrences of `-S' from the command line. Note--this ! command is position dependent. `%' commands in the spec string ! before this one see `-S', `%' commands in the spec string after this one do not. ! `%:FUNCTION(ARGS)' Call the named function FUNCTION, passing it ARGS. ARGS is first processed as a nested spec string, then split into an argument vector in the usual fashion. The function returns a string which ! is processed as if it had appeared literally as part of the ! current spec. The following built-in spec functions are provided: ! ``getenv'' ! The `getenv' spec function takes two arguments: an environment variable name and a string. If the environment variable is not defined, a fatal error is issued. Otherwise, the return value is the value of the environment variable concatenated ! with the string. For example, if `TOPDIR' is defined as ! `/path/to/top', then: %:getenv(TOPDIR /include) ! expands to `/path/to/top/include'. ! ``if-exists'' ! The `if-exists' spec function takes one argument, an absolute ! pathname to a file. If the file exists, `if-exists' returns the pathname. Here is a small example of its usage: *startfile: crt0%O%s %:if-exists(crti%O%s) crtbegin%O%s ! ``if-exists-else'' ! The `if-exists-else' spec function is similar to the ! `if-exists' spec function, except that it takes two ! arguments. The first argument is an absolute pathname to a ! file. If the file exists, `if-exists-else' returns the ! pathname. If it does not exist, it returns the second ! argument. This way, `if-exists-else' can be used to select ! one file or another, based on the existence of the first. ! Here is a small example of its usage: *startfile: crt0%O%s %:if-exists(crti%O%s) \ %:if-exists-else(crtbeginT%O%s crtbegin%O%s) ! ``replace-outfile'' ! The `replace-outfile' spec function takes two arguments. It looks for the first argument in the outfiles array and ! replaces it with the second argument. Here is a small ! example of its usage: %{fgnu-runtime:%:replace-outfile(-lobjc -lobjc-gnu)} ! ``remove-outfile'' ! The `remove-outfile' spec function takes one argument. It ! looks for the first argument in the outfiles array and ! removes it. Here is a small example its usage: %:remove-outfile(-lm) ! ``pass-through-libs'' ! The `pass-through-libs' spec function takes any number of ! arguments. It finds any `-l' options and any non-options ! ending in `.a' (which it assumes are the names of linker ! input library archive files) and returns a result containing ! all the found arguments each prepended by ! `-plugin-opt=-pass-through=' and joined by spaces. This list ! is intended to be passed to the LTO linker plugin. %:pass-through-libs(%G %L %G) ! ``print-asm-header'' ! The `print-asm-header' function takes no arguments and simply prints a banner like: Assembler options --- 10205,10496 ---- *lib: --start-group -lgcc -lc -leval1 --end-group %(old_lib) !

'% --- 11476,11525 ---- In order to facilitate indirect jump on devices with more than 128 Ki bytes of program memory space, there is a special function register ! called 'EIND' that serves as most significant part of the target address ! when 'EICALL' or 'EIJMP' instructions are used. ! Indirect jumps and calls on these devices are handled as follows by the ! compiler and are subject to some limitations: ! * The compiler never sets 'EIND'. ! * The compiler uses 'EIND' implicitely in 'EICALL'/'EIJMP' ! instructions or might read 'EIND' directly in order to emulate an ! indirect call/jump by means of a 'RET' instruction. ! * The compiler assumes that 'EIND' never changes during the startup ! code or during the application. In particular, 'EIND' is not saved/restored in function or interrupt service routine prologue/epilogue. * For indirect calls to functions and computed goto, the linker ! generates _stubs_. Stubs are jump pads sometimes also called ! _trampolines_. Thus, the indirect call/jump jumps to such a stub. The stub contains a direct jump to the desired address. * Linker relaxation must be turned on so that the linker will ! generate the stubs correctly an all situaltion. See the compiler ! option '-mrelax' and the linler option '--relax'. There are corner ! cases where the linker is supposed to generate stubs but aborts ! without relaxation and without a helpful error message. ! * The default linker script is arranged for code with 'EIND = 0'.

If ! you use inline assembler to read from locations outside the 16-bit ! address range and change one of the 'RAMP' registers, you must ! reset it to zero after the access. 3.17.4.3 AVR Built-in Macros ............................ *************** together with direct addressing. *** 11708,11821 **** GCC defines several built-in macros so that the user code can test for the presence or absence of features.

These `-m' options are defined for the DEC Alpha implementations: ! `-mno-soft-float' ! `-msoft-float' Use (do not use) the hardware floating-point instructions for ! floating-point operations. When `-msoft-float' is specified, ! functions in `libgcc.a' are used to perform floating-point operations. Unless they are replaced by routines that emulate the floating-point operations, or compiled in such a way as to call such emulations routines, these routines issue floating-point ! operations. If you are compiling for an Alpha without floating-point operations, you must ensure that the library is built so as not to call them. Note that Alpha implementations without floating-point operations are required to have floating-point registers. ! `-mfp-reg' ! `-mno-fp-regs' Generate code that uses (does not use) the floating-point register ! set. `-mno-fp-regs' implies `-msoft-float'. If the floating-point register set is not used, floating-point operands are passed in integer registers as if they were integers and floating-point ! results are passed in `$0' instead of `$f0'. This is a non-standard calling sequence, so any function with a floating-point argument or return value called by code compiled ! with `-mno-fp-regs' must also be compiled with that option. A typical use of this option is building a kernel that does not use, and hence need not save and restore, any floating-point registers. ! `-mieee' ! The Alpha architecture implements floating-point hardware ! optimized for maximum performance. It is mostly compliant with ! the IEEE floating-point standard. However, for full compliance, ! software assistance is required. This option generates code fully IEEE-compliant code _except_ that the INEXACT-FLAG is not maintained (see below). If this option is turned on, the ! preprocessor macro `_IEEE_FP' is defined during compilation. The resulting code is less efficient but is able to correctly support denormalized numbers and exceptional IEEE values such as not-a-number and plus/minus infinity. Other Alpha compilers call ! this option `-ieee_with_no_inexact'. ! `-mieee-with-inexact' ! This is like `-mieee' except the generated code also maintains the IEEE INEXACT-FLAG. Turning on this option causes the generated code to implement fully-compliant IEEE math. In addition to ! `_IEEE_FP', `_IEEE_FP_EXACT' is defined as a preprocessor macro. On some Alpha implementations the resulting code may execute significantly slower than the code generated by default. Since there is very little code that depends on the INEXACT-FLAG, you should normally not specify this option. Other Alpha compilers ! call this option `-ieee_with_inexact'. ! `-mfp-trap-mode=TRAP-MODE' This option controls what floating-point related traps are enabled. ! Other Alpha compilers call this option `-fptm TRAP-MODE'. The ! trap mode can be set to one of four values: ! `n' ! This is the default (normal) setting. The only traps that ! are enabled are the ones that cannot be disabled in software (e.g., division by zero trap). ! `u' ! In addition to the traps enabled by `n', underflow traps are enabled as well. ! `su' ! Like `u', but the instructions are marked to be safe for software completion (see Alpha architecture manual for details). ! `sui' ! Like `su', but inexact traps are enabled as well. ! `-mfp-rounding-mode=ROUNDING-MODE' Selects the IEEE rounding mode. Other Alpha compilers call this ! option `-fprm ROUNDING-MODE'. The ROUNDING-MODE can be one of: ! `n' ! Normal IEEE rounding mode. Floating-point numbers are ! rounded towards the nearest machine number or towards the ! even machine number in case of a tie. ! `m' Round towards minus infinity. ! `c' Chopped rounding mode. Floating-point numbers are rounded towards zero. ! `d' Dynamic rounding mode. A field in the floating-point control register (FPCR, see Alpha architecture reference manual) controls the rounding mode in effect. The C library initializes this register for rounding towards plus infinity. ! Thus, unless your program modifies the FPCR, `d' corresponds to round towards plus infinity. ! `-mtrap-precision=TRAP-PRECISION' In the Alpha architecture, floating-point traps are imprecise. This means without software assistance it is impossible to recover from a floating trap and program execution normally needs to be ! terminated. GCC can generate code that can assist operating ! system trap handlers in determining the exact location that caused ! a floating-point trap. Depending on the requirements of an application, different levels of precisions can be selected: ! `p' Program precision. This option is the default and means a trap handler can only identify which program caused a floating-point exception. ! `f' Function precision. The trap handler can determine the function that caused a floating-point exception. ! `i' Instruction precision. The trap handler can determine the exact instruction that caused a floating-point exception. Other Alpha compilers provide the equivalent options called ! `-scope_safe' and `-resumption_safe'. ! `-mieee-conformant' This option marks the generated code as IEEE conformant. You must ! not use this option unless you also specify `-mtrap-precision=i' ! and either `-mfp-trap-mode=su' or `-mfp-trap-mode=sui'. Its only ! effect is to emit the line `.eflag 48' in the function prologue of the generated assembly file. ! `-mbuild-constants' ! Normally GCC examines a 32- or 64-bit integer constant to see if ! it can construct it from smaller constants in two or three instructions. If it cannot, it outputs the constant as a literal and generates code to load it from the data segment at run time. --- 12287,12429 ---- 3.17.10 DEC Alpha Options ------------------------- !

Since there is very little code that depends on the INEXACT-FLAG, you should normally not specify this option. Other Alpha compilers ! call this option '-ieee_with_inexact'. ! '-mfp-trap-mode=TRAP-MODE' This option controls what floating-point related traps are enabled. ! Other Alpha compilers call this option '-fptm TRAP-MODE'. The trap ! mode can be set to one of four values: ! 'n' ! This is the default (normal) setting. The only traps that are ! enabled are the ones that cannot be disabled in software (e.g., division by zero trap). ! 'u' ! In addition to the traps enabled by 'n', underflow traps are enabled as well. ! 'su' ! Like 'u', but the instructions are marked to be safe for software completion (see Alpha architecture manual for details). ! 'sui' ! Like 'su', but inexact traps are enabled as well. ! '-mfp-rounding-mode=ROUNDING-MODE' Selects the IEEE rounding mode. Other Alpha compilers call this ! option '-fprm ROUNDING-MODE'. The ROUNDING-MODE can be one of: ! 'n' ! Normal IEEE rounding mode. Floating-point numbers are rounded ! towards the nearest machine number or towards the even machine ! number in case of a tie. ! 'm' Round towards minus infinity. ! 'c' Chopped rounding mode. Floating-point numbers are rounded towards zero. ! 'd' Dynamic rounding mode. A field in the floating-point control register (FPCR, see Alpha architecture reference manual) controls the rounding mode in effect. The C library initializes this register for rounding towards plus infinity. ! Thus, unless your program modifies the FPCR, 'd' corresponds to round towards plus infinity. ! '-mtrap-precision=TRAP-PRECISION' In the Alpha architecture, floating-point traps are imprecise. This means without software assistance it is impossible to recover from a floating trap and program execution normally needs to be ! terminated. GCC can generate code that can assist operating system ! trap handlers in determining the exact location that caused a ! floating-point trap. Depending on the requirements of an application, different levels of precisions can be selected: ! 'p' Program precision. This option is the default and means a trap handler can only identify which program caused a floating-point exception. ! 'f' Function precision. The trap handler can determine the function that caused a floating-point exception. ! 'i' Instruction precision. The trap handler can determine the exact instruction that caused a floating-point exception. Other Alpha compilers provide the equivalent options called ! '-scope_safe' and '-resumption_safe'. ! '-mieee-conformant' This option marks the generated code as IEEE conformant. You must ! not use this option unless you also specify '-mtrap-precision=i' ! and either '-mfp-trap-mode=su' or '-mfp-trap-mode=sui'. Its only ! effect is to emit the line '.eflag 48' in the function prologue of the generated assembly file. ! '-mbuild-constants' ! Normally GCC examines a 32- or 64-bit integer constant to see if it ! can construct it from smaller constants in two or three instructions. If it cannot, it outputs the constant as a literal and generates code to load it from the data segment at run time. *************** These `-m' options are defined for the D *** 12532,12670 **** before it can find the variables and constants in its own data segment. ! `-mbwx' ! `-mno-bwx' ! `-mcix' ! `-mno-cix' ! `-mfix' ! `-mno-fix' ! `-mmax' ! `-mno-max' Indicate whether GCC should generate code to use the optional BWX, CIX, FIX and MAX instruction sets.

These '-m' options are defined for the H8/300 implementations: ! '-mrelax' Shorten some address references at link time, when possible; uses ! the linker option '-relax'. *Note 'ld' and the H8/300: (ld)H8/300, ! for a fuller description. ! '-mh' Generate code for the H8/300H. ! '-ms' Generate code for the H8S. ! '-mn' Generate code for the H8S and H8/300H in the normal mode. This ! switch must be used either with '-mh' or '-ms'. ! '-ms2600' Generate code for the H8S/2600. This switch must be used with ! '-ms'. ! '-mexr' Extended registers are stored on stack before execution of function ! with monitor attribute. Default option is '-mexr'. This option is valid only for H8S targets. ! '-mno-exr' Extended registers are not stored on stack before execution of ! function with monitor attribute. Default option is '-mno-exr'. This option is valid only for H8S targets. ! '-mint32' ! Make 'int' data 32 bits by default. ! '-malign-300' On the H8/300H and H8S, use the same alignment rules as for the H8/300. The default for the H8/300H and H8S is to align longs and ! floats on 4-byte boundaries. '-malign-300' causes them to be aligned on 2-byte boundaries.

These `-m' options are defined for the HPPA family of computers: ! `-march=ARCHITECTURE-TYPE' Generate code for the specified architecture. The choices for ! ARCHITECTURE-TYPE are `1.0' for PA 1.0, `1.1' for PA 1.1, and ! `2.0' for PA 2.0 processors. Refer to `/usr/lib/sched.models' on ! an HP-UX system to determine the proper architecture option for ! your machine. Code compiled for lower numbered architectures runs ! on higher numbered architectures, but not the other way around. ! `-mpa-risc-1-0' ! `-mpa-risc-1-1' ! `-mpa-risc-2-0' ! Synonyms for `-march=1.0', `-march=1.1', and `-march=2.0' respectively. ! `-mbig-switch' ! Generate code suitable for big switch tables. Use this option ! only if the assembler/linker complain about out-of-range branches ! within a switch table. ! `-mjump-in-delay' Fill delay slots of function calls with unconditional jump instructions by modifying the return pointer for the function call to be the target of the conditional jump. ! `-mdisable-fpregs' Prevent floating-point registers from being used in any manner. This is necessary for compiling kernels that perform lazy context switching of floating-point registers. If you use this option and attempt to perform floating-point operations, the compiler aborts. ! `-mdisable-indexing' Prevent the compiler from using indexing address modes. This avoids some rather obscure problems when compiling MIG generated code under MACH. ! `-mno-space-regs' ! Generate code that assumes the target has no space registers. ! This allows GCC to generate faster indirect calls and use unscaled ! index address modes. Such code is suitable for level 0 PA systems and kernels. ! `-mfast-indirect-calls' Generate code that assumes calls never cross space boundaries. This allows GCC to emit code that performs faster indirect calls. This option does not work in the presence of shared libraries or nested functions. ! `-mfixed-range=REGISTER-RANGE' Generate code treating the given register range as fixed registers. A fixed register is one that the register allocator cannot use. This is useful when compiling kernel code. A register range is specified as two registers separated by a dash. Multiple register ranges can be specified separated by a comma. ! `-mlong-load-store' Generate 3-instruction load and store sequences as sometimes ! required by the HP-UX 10 linker. This is equivalent to the `+k' option to the HP compilers. ! `-mportable-runtime' Use the portable calling conventions proposed by HP for ELF systems. ! `-mgas' Enable the use of assembler directives only GAS understands. ! `-mschedule=CPU-TYPE' Schedule code according to the constraints for the machine type ! CPU-TYPE. The choices for CPU-TYPE are `700' `7100', `7100LC', ! `7200', `7300' and `8000'. Refer to `/usr/lib/sched.models' on an HP-UX system to determine the proper scheduling option for your ! machine. The default scheduling is `8000'. ! `-mlinker-opt' Enable the optimization pass in the HP-UX linker. Note this makes ! symbolic debugging impossible. It also triggers a bug in the ! HP-UX 8 and HP-UX 9 linkers in which they give bogus error ! messages when linking some programs. ! `-msoft-float' Generate output containing library calls for floating point. *Warning:* the requisite libraries are not available for all HPPA ! targets. Normally the facilities of the machine's usual C ! compiler are used, but this cannot be done directly in ! cross-compilation. You must make your own arrangements to provide ! suitable library functions for cross-compilation. ! `-msoft-float' changes the calling convention in the output file; therefore, it is only useful if you compile _all_ of a program with ! this option. In particular, you need to compile `libgcc.a', the ! library that comes with GCC, with `-msoft-float' in order for this to work. ! `-msio' ! Generate the predefine, `_SIO', for server IO. The default is ! `-mwsio'. This generates the predefines, `__hp9000s700', ! `__hp9000s700__' and `_WSIO', for workstation IO. These options are available under HP-UX and HI-UX. ! `-mgnu-ld' ! Use options specific to GNU `ld'. This passes `-shared' to `ld' when building a shared library. It is the default when GCC is configured, explicitly or implicitly, with the GNU linker. This ! option does not affect which `ld' is called; it only changes what ! parameters are passed to that `ld'. The `ld' that is called is ! determined by the `--with-ld' configure option, GCC's program ! search path, and finally by the user's `PATH'. The linker used by ! GCC can be printed using `which `gcc -print-prog-name=ld`'. This option is only available on the 64-bit HP-UX GCC, i.e. configured ! with `hppa*64*-*-hpux*'. ! `-mhp-ld' ! Use options specific to HP `ld'. This passes `-b' to `ld' when ! building a shared library and passes `+Accept TypeMismatch' to ! `ld' on all links. It is the default when GCC is configured, ! explicitly or implicitly, with the HP linker. This option does ! not affect which `ld' is called; it only changes what parameters ! are passed to that `ld'.

The linker used by GCC can be ! printed using `which `gcc -print-prog-name=ld`'. This option is only available on the 64-bit HP-UX GCC, i.e. configured with ! `hppa*64*-*-hpux*'. ! `-mlong-calls' Generate code that uses long call sequences. This ensures that a call is always able to reach linker generated stubs. The default ! is to generate long calls only when the distance from the call ! site to the beginning of the function or translation unit, as the ! case may be, exceeds a predefined limit set by the branch type ! being used. The limits for normal calls are 7,600,000 and 240,000 ! bytes, respectively for the PA 2.0 and PA 1.X architectures. ! Sibcalls are always limited at 240,000 bytes. Distances are measured from the beginning of functions when using ! the `-ffunction-sections' option, or when using the `-mgas' and ! `-mno-portable-runtime' options together under HP-UX with the SOM linker.

'-mtune=CPU-TYPE' Tune to CPU-TYPE everything applicable about the generated code, except for the ABI and the set of available instructions. While ! picking a specific CPU-TYPE schedules things appropriately for that ! particular chip, the compiler does not generate any code that cannot run on the default machine type unless you use a ! '-march=CPU-TYPE' option. For example, if GCC is configured for ! i686-pc-linux-gnu then '-mtune=pentium4' generates code that is tuned for Pentium 4 but still runs on i686 machines. ! The choices for CPU-TYPE are the same as for '-march'. In ! addition, '-mtune' supports an extra choice for CPU-TYPE: ! 'generic' Produce code optimized for the most common IA32/AMD64/EM64T processors. If you know the CPU on which your code will run, ! then you should use the corresponding '-mtune' or '-march' ! option instead of '-mtune=generic'. But, if you do not know ! exactly what CPU users of your application will have, then you ! should use this option. As new processors are deployed in the marketplace, the behavior of this option will change. Therefore, if you *************** computers: *** 13410,13466 **** by this option will change to reflect the processors that are most common at the time that version of GCC is released. !

This instruction set is supported by ! Pentium III and newer chips, and in the AMD line by Athlon-4, ! Athlon XP and Athlon MP chips. The earlier version of the SSE instruction set supports only single-precision arithmetic, thus the double and extended-precision arithmetic are still done using 387.

For the i386 compiler, you must use `-march=CPU-TYPE', `-msse' ! or `-msse2' switches to enable SSE extensions and make this option effective.

The usual calling convention has functions return values of types ! `float' and `double' in an FPU register, even if there is no FPU. The idea is that the operating system should emulate an FPU. ! The option `-mno-fp-ret-in-387' causes such values to be returned in ordinary CPU registers instead. ! `-mno-fancy-math-387' ! Some 387 emulators do not support the `sin', `cos' and `sqrt' instructions for the 387. Specify this option to avoid generating ! those instructions. This option is the default on FreeBSD, ! OpenBSD and NetBSD. This option is overridden when `-march' ! indicates that the target CPU always has an FPU and so the ! instruction does not need emulation. These instructions are not ! generated unless you also use the `-funsafe-math-optimizations' ! switch. ! `-malign-double' ! `-mno-align-double' ! Control whether GCC aligns `double', `long double', and `long ! long' variables on a two-word boundary or a one-word boundary. ! Aligning `double' variables on a two-word boundary produces code ! that runs somewhat faster on a Pentium at the expense of more ! memory. ! On x86-64, `-malign-double' is enabled by default. ! *Warning:* if you use the `-malign-double' switch, structures containing the above types are aligned differently than the published application binary interface specifications for the 386 and are not binary compatible with structures in code compiled without that switch. ! `-m96bit-long-double' ! `-m128bit-long-double' ! These switches control the size of `long double' type. The i386 application binary interface specifies the size to be 96 bits, so ! `-m96bit-long-double' is the default in 32-bit mode. ! Modern architectures (Pentium and newer) prefer `long double' to ! be aligned to an 8- or 16-byte boundary. In arrays or structures conforming to the ABI, this is not possible. So specifying ! `-m128bit-long-double' aligns `long double' to a 16-byte boundary ! by padding the `long double' with an additional 32-bit zero. ! In the x86-64 compiler, `-m128bit-long-double' is the default ! choice as its ABI specifies that `long double' is aligned on 16-byte boundary. Notice that neither of these options enable any extra precision ! over the x87 standard of 80 bits for a `long double'. *Warning:* if you override the default value for your target ABI, ! this changes the size of structures and arrays containing `long double' variables, as well as modifying the function calling ! convention for functions taking `long double'. Hence they are not binary-compatible with code compiled without that switch. ! `-mlong-double-64' ! `-mlong-double-80' ! These switches control the size of `long double' type. A size of ! 64 bits makes the `long double' type equivalent to the `double' ! type.

THRESHOLD are placed in the large data section. This value must ! be the same across all objects linked into the binary, and ! defaults to 65535. ! `-mrtd' Use a different function-calling convention, in which functions ! that take a fixed number of arguments return with the `ret NUM' instruction, which pops their arguments while returning. This saves one instruction in the caller since there is no need to pop the arguments there. You can specify that an individual function is called with this ! calling sequence with the function attribute `stdcall'. You can ! also override the `-mrtd' option by using the function attribute ! `cdecl'. *Note Function Attributes::. *Warning:* this calling convention is incompatible with the one normally used on Unix, so you cannot use it if you need to call libraries compiled with the Unix compiler. Also, you must provide function prototypes for all functions that ! take variable numbers of arguments (including `printf'); otherwise incorrect code is generated for calls to those functions. In addition, seriously incorrect code results if you call a function with too many arguments. (Normally, extra arguments are harmlessly ignored.) ! `-mregparm=NUM' Control how many registers are used to pass integer arguments. By default, no registers are used to pass arguments, and at most 3 registers can be used.

This is the default on Solaris 8 and 9 and VxWorks to match the ABI of the Sun Studio compilers until version 12. Later compiler versions ! (starting with Studio 12 Update 1) follow the ABI used by other ! x86 targets, which is the default on Solaris 10 and later. _Only_ ! use this option if you need to remain compatible with existing ! code produced by those previous compiler versions or older ! versions of GCC. - `-mpc32' - `-mpc64' - `-mpc80' Set 80387 floating-point precision to 32, 64 or 80 bits. When ! `-mpc32' is specified, the significands of results of floating-point operations are rounded to 24 bits (single ! precision); `-mpc64' rounds the significands of results of floating-point operations to 53 bits (double precision) and ! `-mpc80' rounds the significands of results of floating-point operations to 64 bits (extended double precision), which is the default.

In addition, variable arguments will be handled incorrectly for 16 byte aligned objects (including x87 long double and __int128), leading to wrong results. You must ! build all modules with '-mpreferred-stack-boundary=3', including any libraries. This includes the system libraries and startup modules. ! '-mincoming-stack-boundary=NUM' Assume the incoming stack is aligned to a 2 raised to NUM byte ! boundary. If '-mincoming-stack-boundary' is not specified, the one ! specified by '-mpreferred-stack-boundary' is used. ! On Pentium and Pentium Pro, 'double' and 'long double' values ! should be aligned to an 8-byte boundary (see '-malign-double') or ! suffer significant run time performance penalties. On Pentium III, ! the Streaming SIMD Extension (SSE) data type '__m128' may not work ! properly if it is not 16-byte aligned. To ensure proper alignment of this values on the stack, the stack ! boundary must be as aligned as that required by any value stored on ! the stack. Further, every function must be generated such that it ! keeps the stack aligned. Thus calling a function compiled with a ! higher preferred stack boundary from a function compiled with a ! lower preferred stack boundary most likely misaligns the stack.

This option instructs GCC to emit a 'cld' instruction in the prologue of functions that use string instructions. String instructions depend on the DF flag to select between autoincrement or autodecrement mode. While the ABI specifies the DF flag to be *************** computers: *** 13792,14083 **** dispatchers. The exception handler can be invoked with the DF flag set, which leads to wrong direction mode when string instructions are used. This option can be enabled by default on 32-bit x86 ! targets by configuring GCC with the `--enable-cld' configure ! option. Generation of `cld' instructions can be suppressed with ! the `-mno-cld' compiler option in this case. ! `-mvzeroupper' ! This option instructs GCC to emit a `vzeroupper' instruction ! before a transfer of control flow out of the function to minimize ! the AVX to SSE transition penalty as well as remove unnecessary ! `zeroupper' intrinsics. ! `-mprefer-avx128' This option instructs GCC to use 128-bit AVX instructions instead of 256-bit AVX instructions in the auto-vectorizer. ! `-mcx16' ! This option enables GCC to generate `CMPXCHG16B' instructions. ! `CMPXCHG16B' allows for atomic operations on 128-bit double ! quadword (or oword) data types. This is useful for ! high-resolution counters that can be updated by multiple ! processors (or cores). This instruction is generated as part of ! atomic built-in functions: see *note __sync Builtins:: or *note ! __atomic Builtins:: for details. ! `-msahf' ! This option enables generation of `SAHF' instructions in 64-bit code. Early Intel Pentium 4 CPUs with Intel 64 support, prior to the introduction of Pentium 4 G1 step in December 2005, lacked the ! `LAHF' and `SAHF' instructions which were supported by AMD64. These are load and store instructions, respectively, for certain ! status flags. In 64-bit mode, the `SAHF' instruction is used to ! optimize `fmod', `drem', and `remainder' built-in functions; see *note Other Builtins:: for details. ! `-mmovbe' ! This option enables use of the `movbe' instruction to implement ! `__builtin_bswap32' and `__builtin_bswap64'. ! `-mcrc32' ! This option enables built-in functions `__builtin_ia32_crc32qi', ! `__builtin_ia32_crc32hi', `__builtin_ia32_crc32si' and ! `__builtin_ia32_crc32di' to generate the `crc32' machine instruction. ! `-mrecip' ! This option enables use of `RCPSS' and `RSQRTSS' instructions (and ! their vectorized variants `RCPPS' and `RSQRTPS') with an ! additional Newton-Raphson step to increase precision instead of ! `DIVSS' and `SQRTSS' (and their vectorized variants) for ! single-precision floating-point arguments. These instructions are ! generated only when `-funsafe-math-optimizations' is enabled ! together with `-finite-math-only' and `-fno-trapping-math'. Note ! that while the throughput of the sequence is higher than the ! throughput of the non-reciprocal instruction, the precision of the ! sequence can be decreased by up to 2 ulp (i.e. the inverse of 1.0 ! equals 0.99999994). ! Note that GCC implements `1.0f/sqrtf(X)' in terms of `RSQRTSS' (or ! `RSQRTPS') already with `-ffast-math' (or the above option ! combination), and doesn't need `-mrecip'. Also note that GCC emits the above sequence with additional Newton-Raphson step for vectorized single-float division and ! vectorized `sqrtf(X)' already with `-ffast-math' (or the above ! option combination), and doesn't need `-mrecip'. ! `-mrecip=OPT' This option controls which reciprocal estimate instructions may be used. OPT is a comma-separated list of options, which may be ! preceded by a `!' to invert the option: ! `all' Enable all estimate instructions. ! `default' ! Enable the default instructions, equivalent to `-mrecip'. ! `none' ! Disable all estimate instructions, equivalent to `-mno-recip'. ! `div' Enable the approximation for scalar division. ! `vec-div' Enable the approximation for vectorized division. ! `sqrt' Enable the approximation for scalar square root. ! `vec-sqrt' Enable the approximation for vectorized square root. ! So, for example, `-mrecip=all,!sqrt' enables all of the reciprocal approximations, except for square root. ! `-mveclibabi=TYPE' Specifies the ABI type to use for vectorizing intrinsics using an ! external library. Supported values for TYPE are `svml' for the ! Intel short vector math library and `acml' for the AMD math core ! library. To use this option, both `-ftree-vectorize' and ! `-funsafe-math-optimizations' have to be enabled, and an SVML or ACML ABI-compatible library must be specified at link time. !

Permissible ! values are `sysv' for the ABI used on GNU/Linux and other systems, ! and `ms' for the Microsoft ABI. The default is to use the ! Microsoft ABI when targeting Microsoft Windows and the SysV ABI on ! all other systems. You can control this behavior for a specific ! function by using the function attribute `ms_abi'/`sysv_abi'. ! *Note Function Attributes::. ! `-mtls-dialect=TYPE' ! Generate code to access thread-local storage using the `gnu' or ! `gnu2' conventions. `gnu' is the conservative default; `gnu2' is more efficient, but it may add compile- and run-time requirements that cannot be satisfied on all systems. ! `-mpush-args' ! `-mno-push-args' Use PUSH operations to store outgoing parameters. This method is ! shorter and usually equally fast as method using SUB/MOV ! operations and is enabled by default. In some cases disabling it ! may improve performance because of improved scheduling and reduced dependencies. ! `-maccumulate-outgoing-args' If enabled, the maximum amount of space required for outgoing arguments is computed in the function prologue. This is faster on most modern CPUs because of reduced dependencies, improved scheduling and reduced stack usage when the preferred stack boundary is not equal to 2. The drawback is a notable increase in ! code size. This switch implies `-mno-push-args'. ! `-mthreads' ! Support thread-safe exception handling on MinGW. Programs that ! rely on thread-safe exception handling must compile and link all ! code with the `-mthreads' option. When compiling, `-mthreads' ! defines `-D_MT'; when linking, it links in a special thread helper ! library `-lmingwthrd' which cleans up per-thread ! exception-handling data. ! `-mno-align-stringops' Do not align the destination of inlined string operations. This switch reduces code size and improves performance in case the destination is already aligned, but GCC doesn't know about it. ! `-minline-all-stringops' By default GCC inlines string operations only when the destination is known to be aligned to least a 4-byte boundary. This enables more inlining and increases code size, but may improve performance ! of code that depends on fast `memcpy', `strlen', and `memset' for short lengths. ! `-minline-stringops-dynamically' For string operations of unknown size, use run-time checks with inline code for small blocks and a library call for large blocks. ! `-mstringop-strategy=ALG' Override the internal decision heuristic for the particular algorithm to use for inlining string operations. The allowed values for ALG are: ! `rep_byte' ! `rep_4byte' ! `rep_8byte' ! Expand using i386 `rep' prefix of the specified size. ! `byte_loop' ! `loop' ! `unrolled_loop' Expand into an inline loop. ! `libcall' Always use a library call. ! `-momit-leaf-frame-pointer' Don't keep the frame pointer in a register for leaf functions. This avoids the instructions to save, set up, and restore frame pointers and makes an extra register available in leaf functions. ! The option `-fomit-leaf-frame-pointer' removes the frame pointer for leaf functions, which might make debugging harder. ! `-mtls-direct-seg-refs' ! `-mno-tls-direct-seg-refs' Controls whether TLS variables may be accessed with offsets from ! the TLS segment register (`%gs' for 32-bit, `%fs' for 64-bit), or whether the thread base pointer must be added. Whether or not this is valid depends on the operating system, and whether it maps the segment to cover the entire TLS area. For systems that use the GNU C Library, the default is on. ! `-msse2avx' ! `-mno-sse2avx' Specify that the assembler should encode SSE instructions with VEX ! prefix. The option `-mavx' turns this on by default. ! `-mfentry' ! `-mno-fentry' ! If profiling is active (`-pg'), put the profiling counter call before the prologue. Note: On x86 architectures the attribute ! `ms_hook_prologue' isn't possible at the moment for `-mfentry' and ! `-pg'. ! `-m8bit-idiv' ! `-mno-8bit-idiv' On some processors, like Intel Atom, 8-bit unsigned integer divide is much faster than 32-bit/64-bit integer divide. This option generates a run-time check. If both dividend and divisor are within range of 0 to 255, 8-bit unsigned integer divide is used instead of 32-bit/64-bit integer divide. ! `-mavx256-split-unaligned-load' ! `-mavx256-split-unaligned-store' Split 32-byte AVX unaligned load and store. ! ! These `-m' switches are supported in addition to the above on x86-64 processors in 64-bit environments. ! `-m32' ! `-m64' ! `-mx32' ! Generate code for a 32-bit or 64-bit environment. The `-m32' ! option sets `int', `long', and pointer types to 32 bits, and generates code that runs on any i386 system. ! The `-m64' option sets `int' to 32 bits and `long' and pointer types to 64 bits, and generates code for the x86-64 architecture. ! For Darwin only the `-m64' option also turns off the `-fno-pic' ! and `-mdynamic-no-pic' options. ! The `-mx32' option sets `int', `long', and pointer types to 32 bits, and generates code for the x86-64 architecture. ! `-mno-red-zone' ! Do not use a so-called "red zone" for x86-64 code. The red zone ! is mandated by the x86-64 ABI; it is a 128-byte area beyond the location of the stack pointer that is not modified by signal or interrupt handlers and therefore can be used for temporary data ! without adjusting the stack pointer. The flag `-mno-red-zone' disables this red zone. ! `-mcmodel=small' ! Generate code for the small code model: the program and its ! symbols must be linked in the lower 2 GB of the address space. ! Pointers are 64 bits. Programs can be statically or dynamically ! linked. This is the default code model. ! `-mcmodel=kernel' Generate code for the kernel code model. The kernel runs in the negative 2 GB of the address space. This model has to be used for Linux kernel code. ! `-mcmodel=medium' Generate code for the medium model: the program is linked in the lower 2 GB of the address space. Small symbols are also placed ! there. Symbols with sizes larger than `-mlarge-data-threshold' ! are put into large data or BSS sections and can be located above ! 2GB. Programs can be statically or dynamically linked. ! `-mcmodel=large' Generate code for the large model. This model makes no assumptions about addresses and sizes of sections. ! `-maddress-mode=long' Generate code for long address mode. This is only supported for 64-bit and x32 environments. It is the default address mode for 64-bit environments. ! `-maddress-mode=short' Generate code for short address mode. This is only supported for 32-bit and x32 environments. It is the default address mode for 32-bit and x32 environments. --- 13738,14027 ---- dispatchers.

This is the default. ! '-mmodel=small' Assume all objects live in the lower 16MB of memory (so that their ! addresses can be loaded with the 'ld24' instruction), and assume ! all subroutines are reachable with the 'bl' instruction. This is the default. The addressability of a particular object can be set with the ! 'model' attribute. ! '-mmodel=medium' Assume objects may be anywhere in the 32-bit address space (the ! compiler generates 'seth/add3' instructions to load their ! addresses), and assume all subroutines are reachable with the 'bl' instruction. ! '-mmodel=large' Assume objects may be anywhere in the 32-bit address space (the ! compiler generates 'seth/add3' instructions to load their addresses), and assume subroutines may not be reachable with the ! 'bl' instruction (the compiler generates the much slower ! 'seth/add3/jl' instruction sequence). ! '-msdata=none' Disable use of the small data area. Variables are put into one of ! '.data', '.bss', or '.rodata' (unless the 'section' attribute has been specified). This is the default. ! The small data area consists of sections '.sdata' and '.sbss'. Objects may be explicitly put in the small data area with the ! 'section' attribute using one of these sections. ! '-msdata=sdata' Put small global and static data in the small data area, but do not generate special code to reference them. ! '-msdata=use' Put small global and static data in the small data area, and generate special instructions to reference them. ! '-G NUM' Put global and static objects less than or equal to NUM bytes into the small data or BSS sections instead of the normal data or BSS ! sections. The default value of NUM is 8. The '-msdata' option ! must be set to one of 'sdata' or 'use' for this option to have any effect. ! All modules should be compiled with the same '-G NUM' value. Compiling with different values of NUM may or may not work; if it doesn't the linker gives an error message--incorrect code is not generated. !

'-mbranch-cost=NUMBER' NUMBER can only be 1 or 2. If it is 1 then branches are preferred over conditional code, if it is 2, then the opposite applies. ! '-mflush-trap=NUMBER' Specifies the trap number to use to flush the cache. The default is 12. Valid numbers are between 0 and 15 inclusive. ! '-mno-flush-trap' Specifies that the cache cannot be flushed by using a trap. ! '-mflush-func=NAME' Specifies the name of the operating system function to call to flush the cache.

This saves one instruction in the caller since there is no need to pop the arguments there. *************** given below. *** 14777,14854 **** compiled with the Unix compiler. Also, you must provide function prototypes for all functions that ! take variable numbers of arguments (including `printf'); otherwise incorrect code is generated for calls to those functions. In addition, seriously incorrect code results if you call a function with too many arguments. (Normally, extra arguments are harmlessly ignored.) ! The `rtd' instruction is supported by the 68010, 68020, 68030, 68040, 68060 and CPU32 processors, but not by the 68000 or 5200. ! `-mno-rtd' ! Do not use the calling conventions selected by `-mrtd'.

The special value `from-abi' selects the most compatible ! architecture for the selected ABI (that is, `mips1' for 32-bit ! ABIs and `mips3' for 64-bit ABIs). ! The native Linux/GNU toolchain also supports the value `native', which selects the best architecture option for the host processor. ! `-march=native' has no effect if GCC does not recognize the processor. ! In processor names, a final `000' can be abbreviated as `k' (for ! example, `-march=r2k'). Prefixes are optional, and `vr' may be ! written `r'. ! Names of the form `Nf2_1' refer to processors with FPUs clocked at ! half the rate of the core, names of the form `Nf1_1' refer to processors with FPUs clocked at the same rate as the core, and ! names of the form `Nf3_2' refer to processors with FPUs clocked a ratio of 3:2 with respect to the core. For compatibility reasons, ! `Nf' is accepted as a synonym for `Nf2_1' while `Nx' and `Bfx' are ! accepted as synonyms for `Nf1_1'. GCC defines two macros based on the value of this option. The ! first is `_MIPS_ARCH', which gives the name of target ! architecture, as a string. The second has the form ! `_MIPS_ARCH_FOO', where FOO is the capitalized value of ! `_MIPS_ARCH'. For example, `-march=r2000' sets `_MIPS_ARCH' to ! `"r2000"' and defines the macro `_MIPS_ARCH_R2000'. ! Note that the `_MIPS_ARCH' macro uses the processor names given above. In other words, it has the full prefix and does not ! abbreviate `000' as `k'. In the case of `from-abi', the macro ! names the resolved architecture (either `"mips1"' or `"mips3"'). ! It names the default architecture when no `-march' option is given. ! `-mtune=ARCH' Optimize for ARCH. Among other things, this option controls the way instructions are scheduled, and the perceived cost of arithmetic operations. The list of ARCH values is the same as for ! `-march'. When this option is not used, GCC optimizes for the processor ! specified by `-march'. By using `-march' and `-mtune' together, ! it is possible to generate code that runs on a family of ! processors, but optimize the code for one particular member of ! that family. ! `-mtune' defines the macros `_MIPS_TUNE' and `_MIPS_TUNE_FOO', ! which work in the same way as the `-march' ones described above. ! `-mips1' ! Equivalent to `-march=mips1'. ! `-mips2' ! Equivalent to `-march=mips2'. ! `-mips3' ! Equivalent to `-march=mips3'. ! `-mips4' ! Equivalent to `-march=mips4'. ! `-mips32' ! Equivalent to `-march=mips32'. ! `-mips32r2' ! Equivalent to `-march=mips32r2'. ! `-mips64' ! Equivalent to `-march=mips64'. ! `-mips64r2' ! Equivalent to `-march=mips64r2'. ! `-mips16' ! `-mno-mips16' Generate (do not generate) MIPS16 code. If GCC is targeting a MIPS32 or MIPS64 architecture, it makes use of the MIPS16e ASE. MIPS16 code generation can also be controlled on a per-function ! basis by means of `mips16' and `nomips16' attributes. *Note Function Attributes::, for more information. ! `-mflip-mips16' Generate MIPS16 code on alternating functions. This option is provided for regression testing of mixed MIPS16/non-MIPS16 code generation, and is not intended for ordinary use in compiling user code. ! `-minterlink-mips16' ! `-mno-interlink-mips16' Require (do not require) that non-MIPS16 code be link-compatible with MIPS16 code. For example, non-MIPS16 code cannot jump directly to MIPS16 code; it must either use a call or an indirect jump. ! `-minterlink-mips16' therefore disables direct jumps unless GCC knows that the target of the jump is not MIPS16. ! `-mabi=32' ! `-mabi=o64' ! `-mabi=n32' ! `-mabi=64' ! `-mabi=eabi' Generate code for the given ABI. Note that the EABI has a 32-bit and a 64-bit variant. GCC normally generates 64-bit code when you select a 64-bit architecture, but ! you can use `-mgp32' to get 32-bit code instead. For information about the O64 ABI, see ! `http://gcc.gnu.org/projects/mipso64-abi.html'. GCC supports a variant of the o32 ABI in which floating-point registers are 64 rather than 32 bits wide. You can select this ! combination with `-mabi=32' `-mfp64'. This ABI relies on the ! `mthc1' and `mfhc1' instructions and is therefore only supported for MIPS32R2 processors. The register assignments for arguments and return values remain the same, but each scalar value is passed in a single 64-bit register rather than a pair of 32-bit registers. For example, scalar ! floating-point values are returned in `$f0' only, not a ! `$f0'/`$f1' pair. The set of call-saved registers also remains ! the same, but all 64 bits are saved. ! `-mabicalls' ! `-mno-abicalls' Generate (do not generate) code that is suitable for SVR4-style ! dynamic objects. `-mabicalls' is the default for SVR4-based systems. ! `-mshared' ! `-mno-shared' Generate (do not generate) code that is fully position-independent, and that can therefore be linked into shared libraries. This ! option only affects `-mabicalls'. ! All `-mabicalls' code has traditionally been position-independent, ! regardless of options like `-fPIC' and `-fpic'. However, as an extension, the GNU toolchain allows executables to use absolute accesses for locally-binding symbols. It can also use shorter GP initialization sequences and generate direct calls to ! locally-defined functions. This mode is selected by `-mno-shared'. ! `-mno-shared' depends on binutils 2.16 or higher and generates objects that can only be linked by the GNU linker. However, the option does not affect the ABI of the final executable; it only ! affects the ABI of relocatable objects. Using `-mno-shared' generally makes executables both smaller and quicker. ! `-mshared' is the default. ! `-mplt' ! `-mno-plt' Assume (do not assume) that the static and dynamic linkers support ! PLTs and copy relocations. This option only affects `-mno-shared -mabicalls'. For the n64 ABI, this option has no effect without ! `-msym32'. ! You can make `-mplt' the default by configuring GCC with ! `--with-mips-plt'. The default is `-mno-plt' otherwise. ! `-mxgot' ! `-mno-xgot' Lift (do not lift) the usual restrictions on the size of the global offset table. --- 15090,15280 ---- 3.17.26 MIPS Options -------------------- ! '-EB' Generate big-endian code. ! '-EL' ! Generate little-endian code. This is the default for 'mips*el-*-*' configurations. ! '-march=ARCH' ! Generate code that runs on ARCH, which can be the name of a generic ! MIPS ISA, or the name of a particular processor. The ISA names ! are: 'mips1', 'mips2', 'mips3', 'mips4', 'mips32', 'mips32r2', ! 'mips64' and 'mips64r2'. The processor names are: '4kc', '4km', ! '4kp', '4ksc', '4kec', '4kem', '4kep', '4ksd', '5kc', '5kf', ! '20kc', '24kc', '24kf2_1', '24kf1_1', '24kec', '24kef2_1', !

'octeon', 'octeon+', 'octeon2', 'orion', 'r2000', 'r3000', 'r3900', ! 'r4000', 'r4400', 'r4600', 'r4650', 'r4700', 'r6000', 'r8000', ! 'rm7000', 'rm9000', 'r10000', 'r12000', 'r14000', 'r16000', 'sb1', ! 'sr71000', 'vr4100', 'vr4111', 'vr4120', 'vr4130', 'vr4300', ! 'vr5000', 'vr5400', 'vr5500', 'xlr' and 'xlp'. The special value ! 'from-abi' selects the most compatible architecture for the ! selected ABI (that is, 'mips1' for 32-bit ABIs and 'mips3' for ! 64-bit ABIs). ! The native Linux/GNU toolchain also supports the value 'native', which selects the best architecture option for the host processor. ! '-march=native' has no effect if GCC does not recognize the processor. ! In processor names, a final '000' can be abbreviated as 'k' (for ! example, '-march=r2k'). Prefixes are optional, and 'vr' may be ! written 'r'. ! Names of the form 'Nf2_1' refer to processors with FPUs clocked at ! half the rate of the core, names of the form 'Nf1_1' refer to processors with FPUs clocked at the same rate as the core, and ! names of the form 'Nf3_2' refer to processors with FPUs clocked a ratio of 3:2 with respect to the core. For compatibility reasons, ! 'Nf' is accepted as a synonym for 'Nf2_1' while 'Nx' and 'Bfx' are ! accepted as synonyms for 'Nf1_1'. GCC defines two macros based on the value of this option. The ! first is '_MIPS_ARCH', which gives the name of target architecture, ! as a string. The second has the form '_MIPS_ARCH_FOO', where FOO ! is the capitalized value of '_MIPS_ARCH'. For example, ! '-march=r2000' sets '_MIPS_ARCH' to '"r2000"' and defines the macro ! '_MIPS_ARCH_R2000'. ! Note that the '_MIPS_ARCH' macro uses the processor names given above. In other words, it has the full prefix and does not ! abbreviate '000' as 'k'. In the case of 'from-abi', the macro ! names the resolved architecture (either '"mips1"' or '"mips3"'). ! It names the default architecture when no '-march' option is given. ! '-mtune=ARCH' Optimize for ARCH. Among other things, this option controls the way instructions are scheduled, and the perceived cost of arithmetic operations. The list of ARCH values is the same as for ! '-march'. When this option is not used, GCC optimizes for the processor ! specified by '-march'. By using '-march' and '-mtune' together, it ! is possible to generate code that runs on a family of processors, ! but optimize the code for one particular member of that family. ! '-mtune' defines the macros '_MIPS_TUNE' and '_MIPS_TUNE_FOO', ! which work in the same way as the '-march' ones described above. ! '-mips1' ! Equivalent to '-march=mips1'. ! '-mips2' ! Equivalent to '-march=mips2'. ! '-mips3' ! Equivalent to '-march=mips3'. ! '-mips4' ! Equivalent to '-march=mips4'. ! '-mips32' ! Equivalent to '-march=mips32'. ! '-mips32r2' ! Equivalent to '-march=mips32r2'. ! '-mips64' ! Equivalent to '-march=mips64'. ! '-mips64r2' ! Equivalent to '-march=mips64r2'. ! '-mips16' ! '-mno-mips16' Generate (do not generate) MIPS16 code. If GCC is targeting a MIPS32 or MIPS64 architecture, it makes use of the MIPS16e ASE. MIPS16 code generation can also be controlled on a per-function ! basis by means of 'mips16' and 'nomips16' attributes. *Note Function Attributes::, for more information. ! '-mflip-mips16' Generate MIPS16 code on alternating functions. This option is provided for regression testing of mixed MIPS16/non-MIPS16 code generation, and is not intended for ordinary use in compiling user code. ! '-minterlink-mips16' ! '-mno-interlink-mips16' Require (do not require) that non-MIPS16 code be link-compatible with MIPS16 code. For example, non-MIPS16 code cannot jump directly to MIPS16 code; it must either use a call or an indirect jump. ! '-minterlink-mips16' therefore disables direct jumps unless GCC knows that the target of the jump is not MIPS16. ! '-mabi=32' ! '-mabi=o64' ! '-mabi=n32' ! '-mabi=64' ! '-mabi=eabi' Generate code for the given ABI. Note that the EABI has a 32-bit and a 64-bit variant. GCC normally generates 64-bit code when you select a 64-bit architecture, but ! you can use '-mgp32' to get 32-bit code instead. For information about the O64 ABI, see ! . GCC supports a variant of the o32 ABI in which floating-point registers are 64 rather than 32 bits wide. You can select this ! combination with '-mabi=32' '-mfp64'. This ABI relies on the ! 'mthc1' and 'mfhc1' instructions and is therefore only supported for MIPS32R2 processors. The register assignments for arguments and return values remain the same, but each scalar value is passed in a single 64-bit register rather than a pair of 32-bit registers. For example, scalar ! floating-point values are returned in '$f0' only, not a '$f0'/'$f1' ! pair. The set of call-saved registers also remains the same, but ! all 64 bits are saved. ! '-mabicalls' ! '-mno-abicalls' Generate (do not generate) code that is suitable for SVR4-style ! dynamic objects. '-mabicalls' is the default for SVR4-based systems. ! '-mshared' !

If this happens, you should recompile your code with `-mxgot'. This works with very large GOTs, although the code is also less efficient, since it takes three instructions to fetch the value of a global symbol. Note that some linkers can create multiple GOTs.

Implement floating-point calculations using library calls instead. ! `-mno-float' ! Equivalent to `-msoft-float', but additionally asserts that the program being compiled does not perform any floating-point operations. This option is presently supported only by some bare-metal MIPS configurations, where it may select a special set of libraries that lack all floating-point support (including, for ! example, the floating-point `printf' formats).

If you compile a module MOD with `-mextern-sdata' `-G NUM' ! `-mgpopt', and MOD references a variable VAR that is no bigger ! than NUM bytes, you must make sure that VAR is placed in a small ! data section. If VAR is defined by another module, you must ! either compile that module with a high-enough `-G' setting or ! attach a `section' attribute to VAR's definition. If VAR is ! common, you must link the application with a high-enough `-G' ! setting. The easiest way of satisfying these restrictions is to compile and ! link every module with the same `-G' option. However, you may ! wish to build a library that supports several different small data limits. You can do this by compiling the library with the highest ! supported `-G' setting and additionally using `-mno-extern-sdata' to stop the library from making assumptions about externally-defined data. ! `-mgpopt' ! `-mno-gpopt' ! Use (do not use) GP-relative accesses for symbols that are known ! to be in a small data section; see `-G', `-mlocal-sdata' and ! `-mextern-sdata'. `-mgpopt' is the default for all configurations. ! `-mno-gpopt' is useful for cases where the `$gp' register might ! not hold the value of `_gp'.

Allocate variables to the read-only data section first if ! possible, then next in the small data section if possible, ! otherwise in data.

The default is `-mcheck-zero-division'. ! `-mdivide-traps' ! `-mdivide-breaks' MIPS systems check for division by zero by generating either a conditional trap or a break instruction. Using traps results in smaller code, but is only supported on MIPS II and later. Also, some versions of the Linux kernel have a bug that prevents trap ! from generating the proper signal (`SIGFPE'). Use ! `-mdivide-traps' to allow conditional traps on architectures that ! support them and `-mdivide-breaks' to force the use of breaks. !

Because always storing floating-point arguments on the stack is inefficient and rarely needed, this ! option is not enabled by default and only is necessary when ! calling subroutines compiled by IBM XL compilers without ! optimization. ! `-mpe' Support "IBM RS/6000 SP" "Parallel Environment" (PE). Link an application written to use message passing with special startup code to enable the application to run. The system must have PE ! installed in the standard location (`/usr/lpp/ppe.poe/'), or the ! `specs' file must be overridden with the `-specs=' option to specify the appropriate directory location. The Parallel ! Environment does not support threads, so the `-mpe' option and the ! `-pthread' option are incompatible. ! `-malign-natural' ! `-malign-power' On AIX, 32-bit Darwin, and 64-bit PowerPC GNU/Linux, the option ! `-malign-natural' overrides the ABI-defined alignment of larger types, such as floating-point doubles, on their natural size-based ! boundary. The option `-malign-power' instructs GCC to follow the ABI-specified alignment rules. GCC defaults to the standard alignment defined in the ABI. On 64-bit Darwin, natural alignment is the default, and ! `-malign-power' is not supported. ! `-msoft-float' ! `-mhard-float' Generate code that does not use (uses) the floating-point register set. Software floating-point emulation is provided if you use the ! `-msoft-float' option, and pass the option to GCC when linking. ! `-msingle-float' ! `-mdouble-float' Generate code for single- or double-precision floating-point ! operations. `-mdouble-float' implies `-msingle-float'. ! `-msimple-fpu' ! Do not generate `sqrt' and `div' instructions for hardware floating-point unit. ! `-mfpu=NAME' Specify type of floating-point unit. Valid values for NAME are ! `sp_lite' (equivalent to `-msingle-float -msimple-fpu'), `dp_lite' ! (equivalent to `-mdouble-float -msimple-fpu'), `sp_full' ! (equivalent to `-msingle-float'), and `dp_full' (equivalent to ! `-mdouble-float'). ! `-mxilinx-fpu' Perform optimizations for the floating-point unit on Xilinx PPC 405/440. ! `-mmultiple' ! `-mno-multiple' Generate code that uses (does not use) the load multiple word instructions and the store multiple word instructions. These instructions are generated by default on POWER systems, and not ! generated on PowerPC systems. Do not use `-mmultiple' on ! little-endian PowerPC systems, since those instructions do not ! work when the processor is in little-endian mode. The exceptions ! are PPC740 and PPC750 which permit these instructions in ! little-endian mode. ! `-mstring' ! `-mno-string' Generate code that uses (does not use) the load string instructions and the store string word instructions to save multiple registers and do small block moves. These instructions are generated by ! default on POWER systems, and not generated on PowerPC systems. ! Do not use `-mstring' on little-endian PowerPC systems, since those instructions do not work when the processor is in little-endian mode. The exceptions are PPC740 and PPC750 which permit these instructions in little-endian mode. ! `-mupdate' ! `-mno-update' Generate code that uses (does not use) the load or store instructions that update the base register to the address of the calculated memory location. These instructions are generated by ! default. If you use `-mno-update', there is a small window ! between the time that the stack pointer is updated and the address ! of the previous frame is stored, which means code that walks the ! stack frame across interrupts or signals may get corrupted data. ! `-mavoid-indexed-addresses' ! `-mno-avoid-indexed-addresses' Generate code that tries to avoid (not avoid) the use of indexed ! load or store instructions. These instructions can incur a performance penalty on Power6 processors in certain situations, such as when stepping through large arrays that cross a 16M boundary. This option is enabled by default when targeting Power6 and disabled otherwise. ! `-mfused-madd' ! `-mno-fused-madd' Generate code that uses (does not use) the floating-point multiply and accumulate instructions. These instructions are generated by default if hardware floating point is used. The machine-dependent ! `-mfused-madd' option is now mapped to the machine-independent ! `-ffp-contract=fast' option, and `-mno-fused-madd' is mapped to ! `-ffp-contract=off'. ! `-mmulhw' ! `-mno-mulhw' Generate code that uses (does not use) the half-word multiply and multiply-accumulate instructions on the IBM 405, 440, 464 and 476 processors. These instructions are generated by default when targeting those processors. ! `-mdlmzb' ! `-mno-dlmzb' ! Generate code that uses (does not use) the string-search `dlmzb' instruction on the IBM 405, 440, 464 and 476 processors. This instruction is generated by default when targeting those processors. ! `-mno-bit-align' ! `-mbit-align' On System V.4 and embedded PowerPC systems do not (do) force structures and unions that contain bit-fields to be aligned to the base type of the bit-field. For example, by default a structure containing nothing but 8 ! `unsigned' bit-fields of length 1 is aligned to a 4-byte boundary ! and has a size of 4 bytes. By using `-mno-bit-align', the structure is aligned to a 1-byte boundary and is 1 byte in size. ! `-mno-strict-align' ! `-mstrict-align' On System V.4 and embedded PowerPC systems do not (do) assume that unaligned memory references are handled by the system. ! `-mrelocatable' ! `-mno-relocatable' Generate code that allows (does not allow) a static executable to be relocated to a different address at run time. A simple embedded PowerPC system loader should relocate the entire contents of ! `.got2' and 4-byte locations listed in the `.fixup' section, a table of 32-bit addresses generated by this option. For this to work, all objects linked together must be compiled with ! `-mrelocatable' or `-mrelocatable-lib'. `-mrelocatable' code aligns the stack to an 8-byte boundary. ! `-mrelocatable-lib' ! `-mno-relocatable-lib' ! Like `-mrelocatable', `-mrelocatable-lib' generates a `.fixup' section to allow static executables to be relocated at run time, ! but `-mrelocatable-lib' does not use the smaller stack alignment ! of `-mrelocatable'. Objects compiled with `-mrelocatable-lib' may ! be linked with objects compiled with any combination of the ! `-mrelocatable' options. ! `-mno-toc' ! `-mtoc' On System V.4 and embedded PowerPC systems do not (do) assume that register 2 contains a pointer to a global area pointing to the addresses used in the program. ! `-mlittle' ! `-mlittle-endian' On System V.4 and embedded PowerPC systems compile code for the ! processor in little-endian mode. The `-mlittle-endian' option is ! the same as `-mlittle'. ! `-mbig' ! `-mbig-endian' On System V.4 and embedded PowerPC systems compile code for the ! processor in big-endian mode. The `-mbig-endian' option is the ! same as `-mbig'. ! `-mdynamic-no-pic' On Darwin and Mac OS X systems, compile code so that it is not relocatable, but that its external references are relocatable. The resulting code is suitable for applications, but not shared libraries. ! `-msingle-pic-base' Treat the register used for PIC addressing as read-only, rather than loading it in the prologue for each function. The runtime system is responsible for initializing this register with an appropriate value before execution begins. ! `-mprioritize-restricted-insns=PRIORITY' ! This option controls the priority that is assigned to ! dispatch-slot restricted instructions during the second scheduling ! pass. The argument PRIORITY takes the value `0', `1', or `2' to ! assign no, highest, or second-highest (respectively) priority to ! dispatch-slot restricted instructions. ! `-msched-costly-dep=DEPENDENCE_TYPE' ! This option controls which dependences are considered costly by ! the target during instruction scheduling. The argument ! DEPENDENCE_TYPE takes one of the following values: ! `no' No dependence is costly. ! `all' All dependences are costly. ! `true_store_to_load' A true dependence from store to load is costly. ! `store_to_load' Any dependence from store to load is costly. ! NUMBER Any dependence for which the latency is greater than or equal to NUMBER is costly. ! `-minsert-sched-nops=SCHEME' This option controls which NOP insertion scheme is used during the second scheduling pass. The argument SCHEME takes one of the following values: ! `no' Don't insert NOPs. ! `pad' Pad with NOPs any dispatch group that has vacant issue slots, according to the scheduler's grouping. ! `regroup_exact' Insert NOPs to force costly dependent insns into separate groups. Insert exactly as many NOPs as needed to force an insn to a new group, according to the estimated processor grouping. ! NUMBER Insert NOPs to force costly dependent insns into separate groups. Insert NUMBER NOPs to force an insn to a new group. ! `-mcall-sysv' On System V.4 and embedded PowerPC systems compile code using calling conventions that adhere to the March 1995 draft of the System V Application Binary Interface, PowerPC processor supplement. This is the default unless you configured GCC using ! `powerpc-*-eabiaix'. ! `-mcall-sysv-eabi' ! `-mcall-eabi' ! Specify both `-mcall-sysv' and `-meabi' options. ! `-mcall-sysv-noeabi' ! Specify both `-mcall-sysv' and `-mno-eabi' options. ! `-mcall-aixdesc' On System V.4 and embedded PowerPC systems compile code for the AIX operating system. ! `-mcall-linux' On System V.4 and embedded PowerPC systems compile code for the Linux-based GNU system. ! `-mcall-freebsd' On System V.4 and embedded PowerPC systems compile code for the FreeBSD operating system. ! `-mcall-netbsd' On System V.4 and embedded PowerPC systems compile code for the NetBSD operating system. ! `-mcall-openbsd' On System V.4 and embedded PowerPC systems compile code for the OpenBSD operating system. ! `-maix-struct-return' Return all structures in memory (as specified by the AIX ABI). ! `-msvr4-struct-return' Return structures smaller than 8 bytes in registers (as specified by the SVR4 ABI). ! `-mabi=ABI-TYPE' Extend the current ABI with a particular extension, or remove such extension. Valid values are ALTIVEC, NO-ALTIVEC, SPE, NO-SPE, IBMLONGDOUBLE, IEEELONGDOUBLE. ! `-mabi=spe' Extend the current ABI with SPE ABI extensions. This does not change the default ABI, instead it adds the SPE ABI extensions to the current ABI. ! `-mabi=no-spe' Disable Book-E SPE ABI extensions for the current ABI. ! `-mabi=ibmlongdouble' Change the current ABI to use IBM extended-precision long double. This is a PowerPC 32-bit SYSV ABI option. ! `-mabi=ieeelongdouble' Change the current ABI to use IEEE extended-precision long double. This is a PowerPC 32-bit Linux ABI option. ! `-mprototype' ! `-mno-prototype' On System V.4 and embedded PowerPC systems assume that all calls to variable argument functions are properly prototyped. Otherwise, ! the compiler must insert an instruction before every ! non-prototyped call to set or clear bit 6 of the condition code ! register (CR) to indicate whether floating-point values are passed ! in the floating-point registers in case the function takes ! variable arguments. With `-mprototype', only calls to prototyped ! variable argument functions set or clear the bit. ! `-msim' On embedded PowerPC systems, assume that the startup module is ! called `sim-crt0.o' and that the standard C libraries are ! `libsim.a' and `libc.a'. This is the default for ! `powerpc-*-eabisim' configurations. ! `-mmvme' On embedded PowerPC systems, assume that the startup module is ! called `crt0.o' and the standard C libraries are `libmvme.a' and ! `libc.a'. ! `-mads' On embedded PowerPC systems, assume that the startup module is ! called `crt0.o' and the standard C libraries are `libads.a' and ! `libc.a'. ! `-myellowknife' On embedded PowerPC systems, assume that the startup module is ! called `crt0.o' and the standard C libraries are `libyk.a' and ! `libc.a'. ! `-mvxworks' On System V.4 and embedded PowerPC systems, specify that you are compiling for a VxWorks system. ! `-memb' On embedded PowerPC systems, set the PPC_EMB bit in the ELF flags ! header to indicate that `eabi' extended relocations are used. ! `-meabi' ! `-mno-eabi' On System V.4 and embedded PowerPC systems do (do not) adhere to the Embedded Applications Binary Interface (EABI), which is a set of modifications to the System V.4 specifications. Selecting ! `-meabi' means that the stack is aligned to an 8-byte boundary, a ! function `__eabi' is called from `main' to set up the EABI ! environment, and the `-msdata' option can use both `r2' and `r13' ! to point to two separate small data areas. Selecting `-mno-eabi' means that the stack is aligned to a 16-byte boundary, no EABI ! initialization function is called from `main', and the `-msdata' ! option only uses `r13' to point to a single small data area. The ! `-meabi' option is on by default if you configured GCC using one ! of the `powerpc*-*-eabi*' options. ! `-msdata=eabi' On System V.4 and embedded PowerPC systems, put small initialized ! `const' global and static data in the `.sdata2' section, which is ! pointed to by register `r2'. Put small initialized non-`const' ! global and static data in the `.sdata' section, which is pointed ! to by register `r13'. Put small uninitialized global and static ! data in the `.sbss' section, which is adjacent to the `.sdata' ! section. The `-msdata=eabi' option is incompatible with the ! `-mrelocatable' option. The `-msdata=eabi' option also sets the ! `-memb' option. ! `-msdata=sysv' On System V.4 and embedded PowerPC systems, put small global and ! static data in the `.sdata' section, which is pointed to by ! register `r13'. Put small uninitialized global and static data in ! the `.sbss' section, which is adjacent to the `.sdata' section. ! The `-msdata=sysv' option is incompatible with the `-mrelocatable' option. ! `-msdata=default' ! `-msdata' ! On System V.4 and embedded PowerPC systems, if `-meabi' is used, ! compile code the same as `-msdata=eabi', otherwise compile code the ! same as `-msdata=sysv'. ! `-msdata=data' On System V.4 and embedded PowerPC systems, put small global data ! in the `.sdata' section. Put small uninitialized global data in ! the `.sbss' section. Do not use register `r13' to address small ! data however. This is the default behavior unless other `-msdata' options are used. ! `-msdata=none' ! `-mno-sdata' On embedded PowerPC systems, put all initialized global and static ! data in the `.data' section, and all uninitialized data in the ! `.bss' section. ! `-mblock-move-inline-limit=NUM' ! Inline all block moves (such as calls to `memcpy' or structure ! copies) less than or equal to NUM bytes. The minimum value for ! NUM is 32 bytes on 32-bit targets and 64 bytes on 64-bit targets. ! The default value is target-specific. ! `-G NUM' On embedded PowerPC systems, put global and static items less than or equal to NUM bytes into the small data or BSS sections instead ! of the normal data or BSS section. By default, NUM is 8. The `-G NUM' switch is also passed to the linker. All modules should be ! compiled with the same `-G NUM' value. ! `-mregnames' ! `-mno-regnames' On System V.4 and embedded PowerPC systems do (do not) emit register names in the assembly language output using symbolic forms. ! `-mlongcall' ! `-mno-longcall' By default assume that all calls are far away so that a longer and more expensive calling sequence is required. This is required for ! calls farther than 32 megabytes (33,554,432 bytes) from the ! current location. A short call is generated if the compiler knows ! the call cannot be that far away. This setting can be overridden ! by the `shortcall' function attribute, or by `#pragma longcall(0)'. Some linkers are capable of detecting out-of-range calls and generating glue code on the fly. On these systems, long calls are --- 16355,16776 ---- The AIX calling convention was extended but not initially documented to handle an obscure K&R C case of calling a function that takes the address of its arguments with fewer arguments than ! declared.

A variant of `inv' where, if no CSE or hoisting opportunities have been found, or if the entire operation has been hoisted to the same place, the last stages of the inverse calculation are intertwined with the final multiply to reduce the overall latency, at the expense of using a few more instructions, and thus offering fewer scheduling opportunities with other code. ! `call' Calls a library function that usually implements the ! `inv:minlat' strategy.

With native Solaris and ! GNU/Linux toolchains, `native' can also be used. ! `-mv8plus' ! `-mno-v8plus' ! With `-mv8plus', GCC generates code for the SPARC-V8+ ABI. The difference from the V8 ABI is that the global and out registers are considered 64 bits wide. This is enabled by default on Solaris in 32-bit mode for all SPARC-V9 processors. ! `-mvis' ! `-mno-vis' ! With `-mvis', GCC generates code that takes advantage of the UltraSPARC Visual Instruction Set extensions. The default is ! `-mno-vis'. ! `-mvis2' ! `-mno-vis2' ! With `-mvis2', GCC generates code that takes advantage of version 2.0 of the UltraSPARC Visual Instruction Set extensions. The ! default is `-mvis2' when targeting a cpu that supports such ! instructions, such as UltraSPARC-III and later. Setting `-mvis2' ! also sets `-mvis'. ! `-mvis3' ! `-mno-vis3' ! With `-mvis3', GCC generates code that takes advantage of version 3.0 of the UltraSPARC Visual Instruction Set extensions. The ! default is `-mvis3' when targeting a cpu that supports such ! instructions, such as niagara-3 and later. Setting `-mvis3' also ! sets `-mvis2' and `-mvis'. ! `-mcbcond' ! `-mno-cbcond' ! With `-mcbcond', GCC generates code that takes advantage of compare-and-branch instructions, as defined in the Sparc ! Architecture 2011. The default is `-mcbcond' when targeting a cpu that supports such instructions, such as niagara-4 and later. ! `-mpopc' ! `-mno-popc' ! With `-mpopc', GCC generates code that takes advantage of the !

These `-m' options are supported in addition to the above on SPARC-V9 processors in 64-bit environments: ! `-m32' ! `-m64' Generate code for a 32-bit or 64-bit environment. The 32-bit environment sets int, long and pointer to 32 bits. The 64-bit environment sets int to 32 bits and long and pointer to 64 bits. ! `-mcmodel=WHICH' Set the code model to one of ! `medlow' The Medium/Low code model: 64-bit addresses, programs must be linked in the low 32 bits of memory. Programs can be statically or dynamically linked. ! `medmid' The Medium/Middle code model: 64-bit addresses, programs must be linked in the low 44 bits of memory, the text and data segments must be less than 2GB in size and the data segment must be located within 2GB of the text segment. ! `medany' ! The Medium/Anywhere code model: 64-bit addresses, programs ! may be linked anywhere in memory, the text and data segments ! must be less than 2GB in size and the data segment must be ! located within 2GB of the text segment. ! `embmedany' The Medium/Anywhere code model for embedded systems: 64-bit addresses, the text and data segments must be less than 2GB in size, both starting anywhere in memory (determined at link ! time). The global register %g4 points to the base of the ! data segment. Programs are statically linked and PIC is not supported. ! `-mmemory-model=MEM-MODEL' Set the memory model in force on the processor to one of ! `default' The default memory model for the processor and operating system. ! `rmo' Relaxed Memory Order ! `pso' Partial Store Order ! `tso' Total Store Order ! `sc' Sequential Consistency ! These memory models are formally defined in Appendix D of the ! Sparc V9 architecture manual, as set in the processor's ! `PSTATE.MM' field. ! `-mstack-bias' ! `-mno-stack-bias' ! With `-mstack-bias', GCC assumes that the stack pointer, and frame pointer if present, are offset by -2047 which must be added back when making stack frame references. This is the default in 64-bit mode. Otherwise, assume no such offset is present. --- 17817,18043 ---- default because it results in a performance loss, especially for floating-point code. ! '-mno-faster-structs' ! '-mfaster-structs' ! With '-mfaster-structs', the compiler assumes that structures should have 8-byte alignment. This enables the use of pairs of ! 'ldd' and 'std' instructions for copies in structure assignment, in ! place of twice as many 'ld' and 'st' pairs. However, the use of ! this changed alignment directly violates the SPARC ABI. Thus, it's ! intended only for use on targets where the developer acknowledges ! that their resulting code is not directly in line with the rules of ! the ABI. ! '-mcpu=CPU_TYPE' Set the instruction set, register set, and instruction scheduling parameters for machine type CPU_TYPE. Supported values for ! CPU_TYPE are 'v7', 'cypress', 'v8', 'supersparc', 'hypersparc', ! 'leon', 'sparclite', 'f930', 'f934', 'sparclite86x', 'sparclet', ! 'tsc701', 'v9', 'ultrasparc', 'ultrasparc3', 'niagara', 'niagara2', ! 'niagara3', and 'niagara4'. Native Solaris and GNU/Linux toolchains also support the value ! 'native', which selects the best architecture option for the host ! processor. '-mcpu=native' has no effect if GCC does not recognize the processor. Default instruction scheduling parameters are used for values that ! select an architecture and not an implementation. These are 'v7', ! 'v8', 'sparclite', 'sparclet', 'v9'. Here is a list of each supported architecture and their supported implementations. ! v7 cypress ! v8 supersparc, hypersparc, leon ! sparclite f930, f934, sparclite86x ! sparclet tsc701 ! v9 ultrasparc, ultrasparc3, niagara, niagara2, niagara3, niagara4 By default (unless configured otherwise), GCC generates code for ! the V7 variant of the SPARC architecture. With '-mcpu=cypress', the compiler additionally optimizes it for the Cypress CY7C602 chip, as used in the SPARCStation/SPARCServer 3xx series. This is also appropriate for the older SPARCStation 1, 2, IPX etc. ! With '-mcpu=v8', GCC generates code for the V8 variant of the SPARC architecture. The only difference from V7 code is that the ! compiler emits the integer multiply and integer divide instructions ! which exist in SPARC-V8 but not in SPARC-V7. With ! '-mcpu=supersparc', the compiler additionally optimizes it for the SuperSPARC chip, as used in the SPARCStation 10, 1000 and 2000 series. ! With '-mcpu=sparclite', GCC generates code for the SPARClite ! variant of the SPARC architecture. This adds the integer multiply, ! integer divide step and scan ('ffs') instructions which exist in ! SPARClite but not in SPARC-V7. With '-mcpu=f930', the compiler ! additionally optimizes it for the Fujitsu MB86930 chip, which is ! the original SPARClite, with no FPU. With '-mcpu=f934', the ! compiler additionally optimizes it for the Fujitsu MB86934 chip, ! which is the more recent SPARClite with FPU. ! With '-mcpu=sparclet', GCC generates code for the SPARClet variant of the SPARC architecture. This adds the integer multiply, ! multiply/accumulate, integer divide step and scan ('ffs') instructions which exist in SPARClet but not in SPARC-V7. With ! '-mcpu=tsc701', the compiler additionally optimizes it for the TEMIC SPARClet chip. ! With '-mcpu=v9', GCC generates code for the V9 variant of the SPARC architecture. This adds 64-bit integer and floating-point move instructions, 3 additional floating-point condition code registers ! and conditional move instructions. With '-mcpu=ultrasparc', the compiler additionally optimizes it for the Sun UltraSPARC I/II/IIi ! chips. With '-mcpu=ultrasparc3', the compiler additionally optimizes it for the Sun UltraSPARC III/III+/IIIi/IIIi+/IV/IV+ ! chips. With '-mcpu=niagara', the compiler additionally optimizes ! it for Sun UltraSPARC T1 chips. With '-mcpu=niagara2', the compiler additionally optimizes it for Sun UltraSPARC T2 chips. ! With '-mcpu=niagara3', the compiler additionally optimizes it for ! Sun UltraSPARC T3 chips. With '-mcpu=niagara4', the compiler additionally optimizes it for Sun UltraSPARC T4 chips. ! '-mtune=CPU_TYPE' Set the instruction scheduling parameters for machine type CPU_TYPE, but do not set the instruction set or register set that ! the option '-mcpu=CPU_TYPE' does. ! The same values for '-mcpu=CPU_TYPE' can be used for ! '-mtune=CPU_TYPE', but the only useful values are those that select ! a particular CPU implementation. Those are 'cypress', !

The difference from the V8 ABI is that the global and out registers are considered 64 bits wide. This is enabled by default on Solaris in 32-bit mode for all SPARC-V9 processors. ! '-mvis' ! '-mno-vis' ! With '-mvis', GCC generates code that takes advantage of the UltraSPARC Visual Instruction Set extensions. The default is ! '-mno-vis'. ! '-mvis2' ! '-mno-vis2' ! With '-mvis2', GCC generates code that takes advantage of version 2.0 of the UltraSPARC Visual Instruction Set extensions.

These `-m' options are supported on the SPU: - `-mwarn-reloc' - `-merror-reloc' The loader for SPU does not handle dynamic relocations. By default, GCC gives an error when it generates code that requires a ! dynamic relocation. `-mno-error-reloc' disables the error, ! `-mwarn-reloc' generates a warning instead. - `-msafe-dma' - `-munsafe-dma' Instructions that initiate or test completion of DMA must not be reordered with respect to loads and stores of the memory that is ! being accessed. With `-munsafe-dma' you must use the `volatile' keyword to protect memory accesses, but that can lead to ! inefficient code in places where the memory is known to not ! change. Rather than mark the memory as volatile, you can use ! `-msafe-dma' to tell the compiler to treat the DMA instructions as ! potentially affecting all memory. - `-mbranch-hints' By default, GCC generates a branch hint instruction to avoid pipeline stalls for always-taken or probably-taken branches. A hint is not generated closer than 8 instructions away from its branch. There is little reason to disable them, except for debugging purposes, or to make an object a little bit smaller. ! `-msmall-mem' ! `-mlarge-mem' By default, GCC generates code assuming that addresses are never ! larger than 18 bits. With `-mlarge-mem' code is generated that assumes a full 32-bit address. ! `-mstdmain' By default, GCC links against startup code that assumes the SPU-style main function interface (which has an unconventional ! parameter list). With `-mstdmain', GCC links your program against ! startup code that assumes a C99-style interface to `main', ! including a local copy of `argv' strings. ! `-mfixed-range=REGISTER-RANGE' Generate code treating the given register range as fixed registers. A fixed register is one that the register allocator cannot use. This is useful when compiling kernel code. A register range is specified as two registers separated by a dash. Multiple register ranges can be specified separated by a comma. ! `-mea32' ! `-mea64' Compile code assuming that pointers to the PPU address space ! accessed via the `__ea' named address space qualifier are either ! 32 or 64 bits wide. The default is 32 bits. As this is an ABI-changing option, all object code in an executable must be compiled with the same setting. ! `-maddress-space-conversion' ! `-mno-address-space-conversion' ! Allow/disallow treating the `__ea' address space as superset of ! the generic address space. This enables explicit type casts ! between `__ea' and generic pointer as well as implicit conversions ! of generic pointers to `__ea' pointers. The default is to allow address space pointer conversions. ! `-mcache-size=CACHE-SIZE' This option controls the version of libgcc that the compiler links ! to an executable and selects a software-managed cache for ! accessing variables in the `__ea' address space with a particular ! cache size. Possible options for CACHE-SIZE are `8', `16', `32', ! `64' and `128'. The default cache size is 64KB. ! `-matomic-updates' ! `-mno-atomic-updates' This option controls the version of libgcc that the compiler links to an executable and selects whether atomic updates to the software-managed cache of PPU-side variables are used. If you use atomic updates, changes to a PPU variable from SPU code using the ! `__ea' named address space qualifier do not interfere with changes to other PPU variables residing in the same cache line from PPU code. If you do not use atomic updates, such interference may occur; however, writing back cache lines is more efficient. The default behavior is to use atomic updates. ! `-mdual-nops' ! `-mdual-nops=N' By default, GCC inserts nops to increase dual issue when it expects it to increase performance. N can be a value from 0 to 10. A smaller N inserts fewer nops. 10 is the default, 0 is the same as ! `-mno-dual-nops'. Disabled with `-Os'. ! `-mhint-max-nops=N' Maximum number of nops to insert for a branch hint. A branch hint must be at least 8 instructions away from the branch it is affecting. GCC inserts up to N nops to enforce this, otherwise it does not generate the branch hint. ! `-mhint-max-distance=N' The encoding of the branch hint instruction limits the hint to be ! within 256 instructions of the branch it is affecting. By ! default, GCC makes sure it is within 125. ! `-msafe-hints' Work around a hardware bug that causes the SPU to stall ! indefinitely. By default, GCC inserts the `hbrp' instruction to make sure this stall won't happen. -  File: gcc.info, Node: System V Options, Next: TILE-Gx Options, Prev: SPU Options, Up: Submodel Options --- 18048,18163 ---- 3.17.41 SPU Options ------------------- !

GCC inspects the locale categories ! `LC_CTYPE' and `LC_MESSAGES' if it has been configured to do so. These locale categories can be set to any value supported by your ! installation. A typical value is `en_GB.UTF-8' for English in the United Kingdom encoded in UTF-8. ! The `LC_CTYPE' environment variable specifies character classification. GCC uses it to determine the character boundaries in a string; this is needed for some multibyte encodings that contain quote and escape characters that are otherwise interpreted as a string end or escape. ! The `LC_MESSAGES' environment variable specifies the language to use in diagnostic messages. ! If the `LC_ALL' environment variable is set, it overrides the value ! of `LC_CTYPE' and `LC_MESSAGES'; otherwise, `LC_CTYPE' and ! `LC_MESSAGES' default to the value of the `LANG' environment variable. If none of these variables are set, GCC defaults to traditional C English behavior. ! `TMPDIR' ! If `TMPDIR' is set, it specifies the directory to use for temporary files. GCC uses temporary files to hold the output of one stage of compilation which is to be used as input to the next stage: for example, the output of the preprocessor, which is the input to the compiler proper. ! `GCC_COMPARE_DEBUG' ! Setting `GCC_COMPARE_DEBUG' is nearly equivalent to passing ! `-fcompare-debug' to the compiler driver. See the documentation ! of this option for more details. ! `GCC_EXEC_PREFIX' ! If `GCC_EXEC_PREFIX' is set, it specifies a prefix to use in the names of the subprograms executed by the compiler. No slash is added when this prefix is combined with the name of a subprogram, but you can specify a prefix that ends with a slash if you wish. ! If `GCC_EXEC_PREFIX' is not set, GCC attempts to figure out an appropriate prefix to use based on the pathname it is invoked with. If GCC cannot find the subprogram using the specified prefix, it tries looking in the usual places for the subprogram. ! The default value of `GCC_EXEC_PREFIX' is `PREFIX/lib/gcc/' where ! PREFIX is the prefix to the installed compiler. In many cases ! PREFIX is the value of `prefix' when you ran the `configure' script. ! Other prefixes specified with `-B' take precedence over this prefix. ! This prefix is also used for finding files such as `crt0.o' that are used for linking. In addition, the prefix is used in an unusual way in finding the directories to search for header files. For each of the standard ! directories whose name normally begins with `/usr/local/lib/gcc' ! (more precisely, with the value of `GCC_INCLUDE_DIR'), GCC tries replacing that beginning with the specified prefix to produce an ! alternate directory name. Thus, with `-Bfoo/', GCC searches ! `foo/bar' just before it searches the standard directory ! `/usr/local/lib/bar'. If a standard directory begins with the configured PREFIX then the value of PREFIX is replaced by ! `GCC_EXEC_PREFIX' when looking for header files. ! `COMPILER_PATH' ! The value of `COMPILER_PATH' is a colon-separated list of ! directories, much like `PATH'. GCC tries the directories thus specified when searching for subprograms, if it can't find the ! subprograms using `GCC_EXEC_PREFIX'. ! `LIBRARY_PATH' ! The value of `LIBRARY_PATH' is a colon-separated list of ! directories, much like `PATH'. When configured as a native compiler, GCC tries the directories thus specified when searching for special linker files, if it can't find them using ! `GCC_EXEC_PREFIX'. Linking using GCC also uses these directories ! when searching for ordinary libraries for the `-l' option (but ! directories specified with `-L' come first). ! `LANG' This variable is used to pass locale information to the compiler. One way in which this information is used is to determine the character set to be used when character literals, string literals and comments are parsed in C and C++. When the compiler is configured to allow multibyte characters, the following values for ! `LANG' are recognized: ! `C-JIS' Recognize JIS characters. ! ! `C-SJIS' Recognize SJIS characters. ! ! `C-EUCJP' Recognize EUCJP characters. ! If `LANG' is not defined, or if it has some other value, then the ! compiler uses `mblen' and `mbtowc' as defined by the default ! locale to recognize and translate multibyte characters. Some additional environment variables affect the behavior of the preprocessor. ! `CPATH' ! `C_INCLUDE_PATH' ! `CPLUS_INCLUDE_PATH' ! `OBJC_INCLUDE_PATH' Each variable's value is a list of directories separated by a ! special character, much like `PATH', in which to look for header ! files. The special character, `PATH_SEPARATOR', is target-dependent and determined at GCC build time. For Microsoft Windows-based targets it is a semicolon, and for almost all other targets it is a colon. ! `CPATH' specifies a list of directories to be searched as if ! specified with `-I', but after any paths given with `-I' options ! on the command line. This environment variable is used regardless ! of which language is being preprocessed. The remaining environment variables apply only when preprocessing the particular language indicated. Each specifies a list of ! directories to be searched as if specified with `-isystem', but ! after any paths given with `-isystem' options on the command line. In all these variables, an empty element instructs the compiler to ! search its current working directory. Empty elements can appear ! at the beginning or end of a path. For instance, if the value of ! `CPATH' is `:/special/include', that has the same effect as ! `-I. -I/special/include'. ! `DEPENDENCIES_OUTPUT' If this variable is set, its value specifies how to output dependencies for Make based on the non-system header files processed by the compiler.

The value of `DEPENDENCIES_OUTPUT' can be just a file name, in which case the Make rules are written to that file, guessing the target name from the source file name.

The keyword `__attribute__' allows you to specify special attributes when making a declaration. This keyword is followed by an attribute specification inside double parentheses.

You may also specify attributes with `__' preceding and following each keyword. This allows you to use them in header files without being ! concerned about a possible macro of the same name. For example, you ! may use `__noreturn__' instead of `noreturn'. *Note Attribute Syntax::, for details of the exact syntax for using attributes. ! `alias ("TARGET")' ! The `alias' attribute causes the declaration to be emitted as an alias for another symbol, which must be specified. For instance, void __f () { /* Do something. */; } void f () __attribute__ ((weak, alias ("__f"))); ! defines `f' to be a weak alias for `__f'. In C++, the mangled ! name for the target must be used. It is an error if `__f' is not defined in the same translation unit. Not all target machines support this attribute. ! `aligned (ALIGNMENT)' This attribute specifies a minimum alignment for the function, measured in bytes. You cannot use this attribute to decrease the alignment of a function, only to increase it. However, when you explicitly specify a function alignment this overrides the effect of the ! `-falign-functions' (*note Optimize Options::) option for this function. ! Note that the effectiveness of `aligned' attributes may be limited by inherent limitations in your linker. On many systems, the linker is only able to arrange for functions to be aligned up to a certain maximum alignment. (For some linkers, the maximum supported alignment may be very very small.) See your linker documentation for further information. ! The `aligned' attribute can also be used for variables and fields (*note Variable Attributes::.) ! `alloc_size' ! The `alloc_size' attribute is used to tell the compiler that the function return value points to memory, where the size is given by one or two of the functions parameters. GCC uses this information ! to improve the correctness of `__builtin_object_size'. ! The function parameter(s) denoting the allocated size are ! specified by one or two integer arguments supplied to the ! attribute. The allocated size is either the value of the single ! function argument specified or the product of the two function ! arguments specified. Argument numbering starts at one. For instance, void* my_calloc(size_t, size_t) __attribute__((alloc_size(1,2))) void my_realloc(void*, size_t) __attribute__((alloc_size(2))) ! declares that `my_calloc' returns memory of the size given by the ! product of parameter 1 and 2 and that `my_realloc' returns memory of the size given by parameter 2. ! `always_inline' Generally, functions are not inlined unless optimization is specified. For functions declared inline, this attribute inlines the function even if no optimization level is specified. ! `gnu_inline' This attribute should be used with a function that is also declared ! with the `inline' keyword. It directs GCC to treat the function ! as if it were defined in gnu90 mode even when compiling in C99 or gnu99 mode. ! If the function is declared `extern', then this definition of the function is used only for inlining. In no case is the function compiled as a standalone function, not even if you take its address explicitly. Such an address becomes an external reference, as if you had only declared the function, and had not defined it. This has almost the effect of a macro. The way to use this is to put a function definition in a header file with this attribute, and put ! another copy of the function, without `extern', in a library file. ! The definition in the header file causes most calls to the ! function to be inlined. If any uses of the function remain, they ! refer to the single copy in the library. Note that the two ! definitions of the functions need not be precisely the same, ! although if they do not have the same effect your program may ! behave oddly. ! In C, if the function is neither `extern' nor `static', then the function is compiled as a standalone function, as well as being inlined where possible. ! This is how GCC traditionally handled functions declared `inline'. ! Since ISO C99 specifies a different semantics for `inline', this function attribute is provided as a transition measure and as a useful feature in its own right. This attribute is available in ! GCC 4.1.3 and later. It is available if either of the ! preprocessor macros `__GNUC_GNU_INLINE__' or ! `__GNUC_STDC_INLINE__' are defined. *Note An Inline Function is ! As Fast As a Macro: Inline. ! In C++, this attribute does not depend on `extern' in any way, but ! it still requires the `inline' keyword to enable its special behavior. ! `artificial' This attribute is useful for small inline wrappers that if possible should appear during debugging as a unit. Depending on the debug info format it either means marking the function as artificial or using the caller location for all instructions within the inlined body. ! `bank_switch' When added to an interrupt handler with the M32C port, causes the prologue and epilogue to use bank switching to preserve the registers rather than saving them on the stack. ! `flatten' Generally, inlining into a function is limited. For a function marked with this attribute, every call inside this function is inlined, if possible. Whether the function itself is considered for inlining depends on its size and the current inlining parameters. ! `error ("MESSAGE")' If this attribute is used on a function declaration and a call to such a function is not eliminated through dead code elimination or other optimizations, an error that includes MESSAGE is diagnosed. This is useful for compile-time checking, especially together with ! `__builtin_constant_p' and inline functions where checking the ! inline function arguments is not possible through `extern char ! [(condition) ? 1 : -1];' tricks. While it is possible to leave ! the function undefined and thus invoke a link failure, when using ! this attribute the problem is diagnosed earlier and with exact ! location of the call even in presence of inline functions or when ! not emitting debugging information. ! `warning ("MESSAGE")' If this attribute is used on a function declaration and a call to such a function is not eliminated through dead code elimination or other optimizations, a warning that includes MESSAGE is diagnosed. This is useful for compile-time checking, especially together with ! `__builtin_constant_p' and inline functions. While it is possible ! to define the function with a message in `.gnu.warning*' section, ! when using this attribute the problem is diagnosed earlier and ! with exact location of the call even in presence of inline ! functions or when not emitting debugging information. ! `cdecl' ! On the Intel 386, the `cdecl' attribute causes the compiler to assume that the calling function pops off the stack space used to pass arguments. This is useful to override the effects of the ! `-mrtd' switch. ! `const' Many functions do not examine any values except their arguments, and have no effects except the return value. Basically this is ! just slightly more strict class than the `pure' attribute below, since function is not allowed to read global memory. Note that a function that has pointer arguments and examines the ! data pointed to must _not_ be declared `const'. Likewise, a ! function that calls a non-`const' function usually must not be ! `const'. It does not make sense for a `const' function to return ! `void'. ! The attribute `const' is not implemented in GCC versions earlier than 2.5.

See your linker documentation for further information. ! The 'aligned' attribute can also be used for variables and fields (*note Variable Attributes::.) ! 'alloc_size' ! The 'alloc_size' attribute is used to tell the compiler that the function return value points to memory, where the size is given by one or two of the functions parameters. GCC uses this information ! to improve the correctness of '__builtin_object_size'. ! The function parameter(s) denoting the allocated size are specified ! by one or two integer arguments supplied to the attribute. The ! allocated size is either the value of the single function argument ! specified or the product of the two function arguments specified. ! Argument numbering starts at one. For instance, void* my_calloc(size_t, size_t) __attribute__((alloc_size(1,2))) void my_realloc(void*, size_t) __attribute__((alloc_size(2))) ! declares that 'my_calloc' returns memory of the size given by the ! product of parameter 1 and 2 and that 'my_realloc' returns memory of the size given by parameter 2. ! 'always_inline' Generally, functions are not inlined unless optimization is specified. For functions declared inline, this attribute inlines the function even if no optimization level is specified. ! 'gnu_inline' This attribute should be used with a function that is also declared ! with the 'inline' keyword. It directs GCC to treat the function as ! if it were defined in gnu90 mode even when compiling in C99 or gnu99 mode. ! If the function is declared 'extern', then this definition of the function is used only for inlining. In no case is the function compiled as a standalone function, not even if you take its address explicitly. Such an address becomes an external reference, as if you had only declared the function, and had not defined it. This has almost the effect of a macro. The way to use this is to put a function definition in a header file with this attribute, and put ! another copy of the function, without 'extern', in a library file. ! The definition in the header file causes most calls to the function ! to be inlined. If any uses of the function remain, they refer to ! the single copy in the library. Note that the two definitions of ! the functions need not be precisely the same, although if they do ! not have the same effect your program may behave oddly. ! In C, if the function is neither 'extern' nor 'static', then the function is compiled as a standalone function, as well as being inlined where possible. ! This is how GCC traditionally handled functions declared 'inline'. ! Since ISO C99 specifies a different semantics for 'inline', this function attribute is provided as a transition measure and as a useful feature in its own right. This attribute is available in ! GCC 4.1.3 and later. It is available if either of the preprocessor ! macros '__GNUC_GNU_INLINE__' or '__GNUC_STDC_INLINE__' are defined. ! *Note An Inline Function is As Fast As a Macro: Inline. ! In C++, this attribute does not depend on 'extern' in any way, but ! it still requires the 'inline' keyword to enable its special behavior. ! 'artificial' This attribute is useful for small inline wrappers that if possible should appear during debugging as a unit. Depending on the debug info format it either means marking the function as artificial or using the caller location for all instructions within the inlined body. ! 'bank_switch' When added to an interrupt handler with the M32C port, causes the prologue and epilogue to use bank switching to preserve the registers rather than saving them on the stack. ! 'flatten' Generally, inlining into a function is limited. For a function marked with this attribute, every call inside this function is inlined, if possible. Whether the function itself is considered for inlining depends on its size and the current inlining parameters. ! 'error ("MESSAGE")' If this attribute is used on a function declaration and a call to such a function is not eliminated through dead code elimination or other optimizations, an error that includes MESSAGE is diagnosed. This is useful for compile-time checking, especially together with ! '__builtin_constant_p' and inline functions where checking the ! inline function arguments is not possible through 'extern char ! [(condition) ? 1 : -1];' tricks. While it is possible to leave the ! function undefined and thus invoke a link failure, when using this ! attribute the problem is diagnosed earlier and with exact location ! of the call even in presence of inline functions or when not ! emitting debugging information. ! 'warning ("MESSAGE")' If this attribute is used on a function declaration and a call to such a function is not eliminated through dead code elimination or other optimizations, a warning that includes MESSAGE is diagnosed. This is useful for compile-time checking, especially together with ! '__builtin_constant_p' and inline functions. While it is possible ! to define the function with a message in '.gnu.warning*' section, ! when using this attribute the problem is diagnosed earlier and with ! exact location of the call even in presence of inline functions or ! when not emitting debugging information. ! 'cdecl' ! On the Intel 386, the 'cdecl' attribute causes the compiler to assume that the calling function pops off the stack space used to pass arguments. This is useful to override the effects of the ! '-mrtd' switch. ! 'const' Many functions do not examine any values except their arguments, and have no effects except the return value. Basically this is ! just slightly more strict class than the 'pure' attribute below, since function is not allowed to read global memory. Note that a function that has pointer arguments and examines the ! data pointed to must _not_ be declared 'const'. Likewise, a ! function that calls a non-'const' function usually must not be ! 'const'. It does not make sense for a 'const' function to return ! 'void'. ! The attribute 'const' is not implemented in GCC versions earlier than 2.5. An alternative way to declare that a function has no side effects, which works in the current version and in some older versions, is as follows: *************** attributes. *** 22256,22272 **** extern const intfn square; This approach does not work in GNU C++ from 2.6.0 on, since the ! language specifies that the `const' must be attached to the return value. ! `constructor' ! `destructor' ! `constructor (PRIORITY)' ! `destructor (PRIORITY)' ! The `constructor' attribute causes the function to be called ! automatically before execution enters `main ()'. Similarly, the ! `destructor' attribute causes the function to be called ! automatically after `main ()' completes or `exit ()' is called. Functions with these attributes are useful for initializing data that is used implicitly during the execution of the program. --- 22094,22110 ---- extern const intfn square; This approach does not work in GNU C++ from 2.6.0 on, since the ! language specifies that the 'const' must be attached to the return value. !

You can use `__declspec(dllexport)' as a synonym for ! `__attribute__ ((dllexport))' for compatibility with other ! compilers. !

On Microsoft Windows and Symbian OS targets, the `dllimport' attribute causes the compiler to reference a function or variable via a global pointer to a pointer that is set up by the DLL ! exporting the symbol. The attribute implies `extern'. On Microsoft Windows targets, the pointer name is formed by combining ! `_imp__' and the function or variable name. ! You can use `__declspec(dllimport)' as a synonym for ! `__attribute__ ((dllimport))' for compatibility with other ! compilers. ! On systems that support the `visibility' attribute, this attribute also implies "default" visibility. It is an error to explicitly specify any other visibility. Currently, the attribute is ignored for inlined functions. If the attribute is applied to a symbol _definition_, an error is ! reported. If a symbol previously declared `dllimport' is later defined, the attribute is ignored in subsequent references, and a warning is emitted. The attribute is also overridden by a ! subsequent declaration as `dllexport'. ! When applied to C++ classes, the attribute marks non-inlined ! member functions and static data members as imports. However, the attribute is ignored for virtual methods to allow creation of vtables using thunks. ! On the SH Symbian OS target the `dllimport' attribute also has another affect--it can cause the vtable and run-time type information for a class to be exported. This happens when the class has a dllimported constructor or a non-inline, non-pure ! virtual function and, for either of those two conditions, the ! class also has an inline constructor or destructor and has a key ! function that is defined in the current translation unit. ! For Microsoft Windows targets the use of the `dllimport' attribute on functions is not necessary, but provides a small performance benefit by eliminating a thunk in the DLL. The use of the ! `dllimport' attribute on imported variables was required on older versions of the GNU linker, but can now be avoided by passing the ! `--enable-auto-import' switch to the GNU linker. As with functions, using the attribute for a variable eliminates a thunk in the DLL. One drawback to using this attribute is that a pointer to a ! _variable_ marked as `dllimport' cannot be used as a constant ! address. However, a pointer to a _function_ with the `dllimport' attribute can be used as a constant initializer; in this case, the address of a stub function in the import lib is referenced. On Microsoft Windows targets, the attribute can be disabled for ! functions by setting the `-mnop-fun-dllimport' flag. ! `eightbit_data' ! Use this attribute on the H8/300, H8/300H, and H8S to indicate ! that the specified variable should be placed into the eight-bit ! data section. The compiler generates more efficient code for ! certain operations on data in the eight-bit data area. Note the ! eight-bit data area is limited to 256 bytes of data. You must use GAS and GLD from GNU binutils version 2.7 or later for this attribute to work correctly. ! `exception_handler' Use this attribute on the Blackfin to indicate that the specified function is an exception handler. The compiler generates function entry and exit sequences suitable for use in an exception handler when this attribute is present. ! `externally_visible' This attribute, attached to a global variable or function, ! nullifies the effect of the `-fwhole-program' command-line option, so the object remains visible outside the current compilation unit. ! If `-fwhole-program' is used together with `-flto' and `gold' is ! used as the linker plugin, `externally_visible' attributes are ! automatically added to functions (not variable yet due to a ! current `gold' issue) that are accessed outside of LTO objects ! according to resolution file produced by `gold'. For other ! linkers that cannot generate resolution file, explicit ! `externally_visible' attributes are still necessary. ! `far' ! On 68HC11 and 68HC12 the `far' attribute causes the compiler to ! use a calling convention that takes care of switching memory banks ! when entering and leaving a function. This calling convention is ! also the default when using the `-mlong-calls' option. ! On 68HC12 the compiler uses the `call' and `rtc' instructions to call and return from a function. On 68HC11 the compiler generates a sequence of instructions to invoke a board-specific routine to switch the memory bank and call ! the real function. The board-specific routine simulates a `call'. At the end of a function, it jumps to a board-specific routine ! instead of using `rts'. The board-specific return routine ! simulates the `rtc'. On MeP targets this causes the compiler to use a calling convention that assumes the called function is too far away for the built-in addressing modes. ! `fast_interrupt' Use this attribute on the M32C and RX ports to indicate that the specified function is a fast interrupt handler. This is just like ! the `interrupt' attribute, except that `freit' is used to return ! instead of `reit'. ! `fastcall' ! On the Intel 386, the `fastcall' attribute causes the compiler to pass the first argument (if of integral type) in the register ECX and the second argument (if of integral type) in the register EDX. Subsequent and other typed arguments are passed on the stack. The ! called function pops the arguments off the stack. If the number ! of arguments is variable all arguments are pushed on the stack. ! `thiscall' ! On the Intel 386, the `thiscall' attribute causes the compiler to pass the first argument (if of integral type) in the register ECX. ! Subsequent and other typed arguments are passed on the stack. The ! called function pops the arguments off the stack. If the number ! of arguments is variable all arguments are pushed on the stack. ! The `thiscall' attribute is intended for C++ non-static member ! functions. As a GCC extension, this calling convention can be ! used for C functions and for static member methods. ! `format (ARCHETYPE, STRING-INDEX, FIRST-TO-CHECK)' ! The `format' attribute specifies that a function takes `printf', ! `scanf', `strftime' or `strfmon' style arguments that should be type-checked against a format string. For example, the declaration: --- 22177,22313 ---- For Microsoft Windows targets there are alternative methods for including the symbol in the DLL's export table such as using a !

The ! 'thiscall' attribute is intended for C++ non-static member ! functions. As a GCC extension, this calling convention can be used ! for C functions and for static member methods. ! 'format (ARCHETYPE, STRING-INDEX, FIRST-TO-CHECK)' ! The 'format' attribute specifies that a function takes 'printf', ! 'scanf', 'strftime' or 'strfmon' style arguments that should be type-checked against a format string. For example, the declaration: *************** attributes. *** 22480,22608 **** my_printf (void *my_object, const char *my_format, ...) __attribute__ ((format (printf, 2, 3))); ! causes the compiler to check the arguments in calls to `my_printf' ! for consistency with the `printf' style format string argument ! `my_format'. The parameter ARCHETYPE determines how the format string is ! interpreted, and should be `printf', `scanf', `strftime', ! `gnu_printf', `gnu_scanf', `gnu_strftime' or `strfmon'. (You can ! also use `__printf__', `__scanf__', `__strftime__' or ! `__strfmon__'.) On MinGW targets, `ms_printf', `ms_scanf', and ! `ms_strftime' are also present. ARCHETYPE values such as `printf' refer to the formats accepted by the system's C runtime library, ! while values prefixed with `gnu_' always refer to the formats accepted by the GNU C Library. On Microsoft Windows targets, ! values prefixed with `ms_' refer to the formats accepted by the ! `msvcrt.dll' library. The parameter STRING-INDEX specifies which argument is the format string argument (starting from 1), while ! FIRST-TO-CHECK is the number of the first argument to check ! against the format string. For functions where the arguments are ! not available to be checked (such as `vprintf'), specify the third parameter as zero. In this case the compiler only checks the ! format string for consistency. For `strftime' formats, the third parameter is required to be zero. Since non-static C++ methods ! have an implicit `this' argument, the arguments of such methods should be counted from two, not one, when giving values for STRING-INDEX and FIRST-TO-CHECK. ! In the example above, the format string (`my_format') is the second ! argument of the function `my_print', and the arguments to check start with the third argument, so the correct parameters for the format attribute are 2 and 3. ! The `format' attribute allows you to identify your own functions that take format strings as arguments, so that GCC can check the calls to these functions for errors. The compiler always (unless ! `-ffreestanding' or `-fno-builtin' is used) checks formats for the ! standard library functions `printf', `fprintf', `sprintf', ! `scanf', `fscanf', `sscanf', `strftime', `vprintf', `vfprintf' and ! `vsprintf' whenever such warnings are requested (using ! `-Wformat'), so there is no need to modify the header file ! `stdio.h'. In C99 mode, the functions `snprintf', `vsnprintf', ! `vscanf', `vfscanf' and `vsscanf' are also checked. Except in ! strictly conforming C standard modes, the X/Open function ! `strfmon' is also checked as are `printf_unlocked' and ! `fprintf_unlocked'. *Note Options Controlling C Dialect: C ! Dialect Options. ! For Objective-C dialects, `NSString' (or `__NSString__') is recognized in the same context. Declarations including these ! format attributes are parsed for correct syntax, however the ! result of checking of such format strings is not yet defined, and ! is not carried out by this version of the compiler. The target may also provide additional types of format checks. *Note Format Checks Specific to Particular Target Machines: Target Format Checks. ! `format_arg (STRING-INDEX)' ! The `format_arg' attribute specifies that a function takes a format ! string for a `printf', `scanf', `strftime' or `strfmon' style ! function and modifies it (for example, to translate it into ! another language), so the result can be passed to a `printf', ! `scanf', `strftime' or `strfmon' style function (with the ! remaining arguments to the format function the same as they would ! have been for the unmodified string). For example, the ! declaration: extern char * my_dgettext (char *my_domain, const char *my_format) __attribute__ ((format_arg (2))); ! causes the compiler to check the arguments in calls to a `printf', ! `scanf', `strftime' or `strfmon' type function, whose format ! string argument is a call to the `my_dgettext' function, for ! consistency with the format string argument `my_format'. If the ! `format_arg' attribute had not been specified, all the compiler ! could tell in such calls to format functions would be that the ! format string argument is not constant; this would generate a ! warning when `-Wformat-nonliteral' is used, but the calls could ! not be checked without the attribute. The parameter STRING-INDEX specifies which argument is the format string argument (starting from one). Since non-static C++ methods ! have an implicit `this' argument, the arguments of such methods should be counted from two. ! The `format_arg' attribute allows you to identify your own functions that modify format strings, so that GCC can check the ! calls to `printf', `scanf', `strftime' or `strfmon' type function whose operands are a call to one of your own function. The ! compiler always treats `gettext', `dgettext', and `dcgettext' in this manner except when strict ISO C support is requested by ! `-ansi' or an appropriate `-std' option, or `-ffreestanding' or ! `-fno-builtin' is used. *Note Options Controlling C Dialect: C Dialect Options. ! For Objective-C dialects, the `format-arg' attribute may refer to ! an `NSString' reference for compatibility with the `format' attribute above. ! The target may also allow additional types in `format-arg' attributes. *Note Format Checks Specific to Particular Target Machines: Target Format Checks. ! `function_vector' ! Use this attribute on the H8/300, H8/300H, and H8S to indicate ! that the specified function should be called through the function vector. Calling a function through the function vector reduces ! code size, however; the function vector has a limited size ! (maximum 128 entries on the H8/300 and 64 entries on the H8/300H ! and H8S) and shares space with the interrupt vector. On SH2A targets, this attribute declares a function to be called using the TBR relative addressing mode. The argument to this attribute is the entry number of the same function in a vector table containing all the TBR relative addressable functions. For ! correct operation the TBR must be setup accordingly to point to ! the start of the vector table before any functions with this ! attribute are invoked. Usually a good place to do the ! initialization is the startup routine. The TBR relative vector ! table can have at max 256 function entries. The jumps to these ! functions are generated using a SH2A specific, non delayed branch ! instruction JSR/N @(disp8,TBR). You must use GAS and GLD from GNU ! binutils version 2.7 or later for this attribute to work correctly. Please refer the example of M16C target, to see the use of this attribute while declaring a function, --- 22315,22441 ---- my_printf (void *my_object, const char *my_format, ...) __attribute__ ((format (printf, 2, 3))); ! causes the compiler to check the arguments in calls to 'my_printf' ! for consistency with the 'printf' style format string argument ! 'my_format'. The parameter ARCHETYPE determines how the format string is ! interpreted, and should be 'printf', 'scanf', 'strftime', ! 'gnu_printf', 'gnu_scanf', 'gnu_strftime' or 'strfmon'. (You can ! also use '__printf__', '__scanf__', '__strftime__' or ! '__strfmon__'.) On MinGW targets, 'ms_printf', 'ms_scanf', and ! 'ms_strftime' are also present. ARCHETYPE values such as 'printf' refer to the formats accepted by the system's C runtime library, ! while values prefixed with 'gnu_' always refer to the formats accepted by the GNU C Library. On Microsoft Windows targets, ! values prefixed with 'ms_' refer to the formats accepted by the ! 'msvcrt.dll' library. The parameter STRING-INDEX specifies which argument is the format string argument (starting from 1), while ! FIRST-TO-CHECK is the number of the first argument to check against ! the format string. For functions where the arguments are not ! available to be checked (such as 'vprintf'), specify the third parameter as zero. In this case the compiler only checks the ! format string for consistency. For 'strftime' formats, the third parameter is required to be zero. Since non-static C++ methods ! have an implicit 'this' argument, the arguments of such methods should be counted from two, not one, when giving values for STRING-INDEX and FIRST-TO-CHECK. ! In the example above, the format string ('my_format') is the second ! argument of the function 'my_print', and the arguments to check start with the third argument, so the correct parameters for the format attribute are 2 and 3. ! The 'format' attribute allows you to identify your own functions that take format strings as arguments, so that GCC can check the calls to these functions for errors. The compiler always (unless ! '-ffreestanding' or '-fno-builtin' is used) checks formats for the ! standard library functions 'printf', 'fprintf', 'sprintf', 'scanf', ! 'fscanf', 'sscanf', 'strftime', 'vprintf', 'vfprintf' and ! 'vsprintf' whenever such warnings are requested (using '-Wformat'), ! so there is no need to modify the header file 'stdio.h'. In C99 ! mode, the functions 'snprintf', 'vsnprintf', 'vscanf', 'vfscanf' ! and 'vsscanf' are also checked. Except in strictly conforming C ! standard modes, the X/Open function 'strfmon' is also checked as ! are 'printf_unlocked' and 'fprintf_unlocked'. *Note Options !

The target may also provide additional types of format checks. *Note Format Checks Specific to Particular Target Machines: Target Format Checks. ! 'format_arg (STRING-INDEX)' ! The 'format_arg' attribute specifies that a function takes a format ! string for a 'printf', 'scanf', 'strftime' or 'strfmon' style ! function and modifies it (for example, to translate it into another ! language), so the result can be passed to a 'printf', 'scanf', ! 'strftime' or 'strfmon' style function (with the remaining ! arguments to the format function the same as they would have been ! for the unmodified string). For example, the declaration: extern char * my_dgettext (char *my_domain, const char *my_format) __attribute__ ((format_arg (2))); ! causes the compiler to check the arguments in calls to a 'printf', ! 'scanf', 'strftime' or 'strfmon' type function, whose format string ! argument is a call to the 'my_dgettext' function, for consistency ! with the format string argument 'my_format'. If the 'format_arg' ! attribute had not been specified, all the compiler could tell in ! such calls to format functions would be that the format string ! argument is not constant; this would generate a warning when ! '-Wformat-nonliteral' is used, but the calls could not be checked ! without the attribute. The parameter STRING-INDEX specifies which argument is the format string argument (starting from one). Since non-static C++ methods ! have an implicit 'this' argument, the arguments of such methods should be counted from two. ! The 'format_arg' attribute allows you to identify your own functions that modify format strings, so that GCC can check the ! calls to 'printf', 'scanf', 'strftime' or 'strfmon' type function whose operands are a call to one of your own function. The ! compiler always treats 'gettext', 'dgettext', and 'dcgettext' in this manner except when strict ISO C support is requested by ! '-ansi' or an appropriate '-std' option, or '-ffreestanding' or ! '-fno-builtin' is used. *Note Options Controlling C Dialect: C Dialect Options. ! For Objective-C dialects, the 'format-arg' attribute may refer to ! an 'NSString' reference for compatibility with the 'format' attribute above. ! The target may also allow additional types in 'format-arg' attributes. *Note Format Checks Specific to Particular Target Machines: Target Format Checks. ! 'function_vector' ! Use this attribute on the H8/300, H8/300H, and H8S to indicate that ! the specified function should be called through the function vector. Calling a function through the function vector reduces ! code size, however; the function vector has a limited size (maximum ! 128 entries on the H8/300 and 64 entries on the H8/300H and H8S) ! and shares space with the interrupt vector. On SH2A targets, this attribute declares a function to be called using the TBR relative addressing mode. The argument to this attribute is the entry number of the same function in a vector table containing all the TBR relative addressable functions. For ! correct operation the TBR must be setup accordingly to point to the ! start of the vector table before any functions with this attribute ! are invoked. Usually a good place to do the initialization is the ! startup routine. The TBR relative vector table can have at max 256 ! function entries. The jumps to these functions are generated using ! a SH2A specific, non delayed branch instruction JSR/N @(disp8,TBR). !

The compiler omits generate prologue/epilogue sequences and replaces the return instruction ! with a `sleep' instruction. This attribute is available only on fido. ! `isr' Use this attribute on ARM to write Interrupt Service Routines. ! This is an alias to the `interrupt' attribute above. ! `kspisusp' ! When used together with `interrupt_handler', `exception_handler' ! or `nmi_handler', code is generated to load the stack pointer from ! the USP register in the function prologue. ! `l1_text' This attribute specifies a function to be placed into L1 ! Instruction SRAM. The function is put into a specific section ! named `.l1.text'. With `-mfdpic', function calls with a such function as the callee or caller uses inlined PLT. ! `l2' On the Blackfin, this attribute specifies a function to be placed into L2 SRAM. The function is put into a specific section named ! `.l1.text'. With `-mfdpic', callers of such functions use an inlined PLT. ! `leaf' Calls to external functions with this attribute must return to the current compilation unit only by return or by exception handling. In particular, leaf functions are not allowed to call callback ! function passed to it from the current compilation unit or ! directly call functions exported by the unit or longjmp into the ! unit. Leaf function might still call functions from other ! compilation units and thus they are not necessarily leaf in the ! sense that they contain no function calls at all. ! The attribute is intended for library functions to improve ! dataflow analysis. The compiler takes the hint that any data not ! escaping the current compilation unit can not be used or modified ! by the leaf function. For example, the `sin' function is a leaf ! function, but `qsort' is not. Note that leaf functions might invoke signals and signal handlers might be defined in the current compilation unit and use static variables. The only compliant way to write such a signal handler ! is to declare such variables `volatile'. ! The attribute has no effect on functions defined within the ! current compilation unit. This is to allow easy merging of ! multiple compilation units into one, for example, by using the ! link-time optimization. For this reason the attribute is not ! allowed on types to annotate indirect calls. ! `long_call/short_call' ! This attribute specifies how a particular function is called on ! ARM and Epiphany. Both attributes override the `-mlong-calls' ! (*note ARM Options::) command-line switch and `#pragma long_calls' ! settings. The `long_call' attribute indicates that the function might be far away from the call site and require a different (more ! expensive) calling sequence. The `short_call' attribute always ! places the offset to the function from the call site into the `BL' instruction directly. ! `longcall/shortcall' ! On the Blackfin, RS/6000 and PowerPC, the `longcall' attribute indicates that the function might be far away from the call site and require a different (more expensive) calling sequence. The ! `shortcall' attribute indicates that the function is always close enough for the shorter calling sequence to be used. These ! attributes override both the `-mlongcall' switch and, on the ! RS/6000 and PowerPC, the `#pragma longcall' setting. *Note RS/6000 and PowerPC Options::, for more information on whether long calls are necessary. ! `long_call/near/far' These attributes specify how a particular function is called on ! MIPS. The attributes override the `-mlong-calls' (*note MIPS ! Options::) command-line switch. The `long_call' and `far' attributes are synonyms, and cause the compiler to always call the function by first loading its address into a register, and then ! using the contents of that register. The `near' attribute has the opposite effect; it specifies that non-PIC calls should be made ! using the more efficient `jal' instruction. ! `malloc' ! The `malloc' attribute is used to tell the compiler that a function ! may be treated as if any non-`NULL' pointer it returns cannot ! alias any other pointer valid when the function returns and that ! the memory has undefined content. This often improves ! optimization. Standard functions with this property include ! `malloc' and `calloc'. `realloc'-like functions do not have this ! property as the memory pointed to does not have undefined content. ! `mips16/nomips16' ! On MIPS targets, you can use the `mips16' and `nomips16' function ! attributes to locally select or turn off MIPS16 code generation. ! A function with the `mips16' attribute is emitted as MIPS16 code, while MIPS16 code generation is disabled for functions with the ! `nomips16' attribute. These attributes override the `-mips16' and ! `-mno-mips16' options on the command line (*note MIPS Options::). When compiling files containing mixed MIPS16 and non-MIPS16 code, ! the preprocessor symbol `__mips16' reflects the setting on the command line, not that within individual functions. Mixed MIPS16 and non-MIPS16 code may interact badly with some GCC extensions ! such as `__builtin_apply' (*note Constructing Calls::). - `model (MODEL-NAME)' On the M32R/D, use this attribute to set the addressability of an object, and of the code generated for a function. The identifier ! MODEL-NAME is one of `small', `medium', or `large', representing each of the code models. Small model objects live in the lower 16MB of memory (so that their ! addresses can be loaded with the `ld24' instruction), and are ! callable with the `bl' instruction. Medium model objects may live anywhere in the 32-bit address space ! (the compiler generates `seth/add3' instructions to load their ! addresses), and are callable with the `bl' instruction. Large model objects may live anywhere in the 32-bit address space ! (the compiler generates `seth/add3' instructions to load their ! addresses), and may not be reachable with the `bl' instruction ! (the compiler generates the much slower `seth/add3/jl' instruction sequence). On IA-64, use this attribute to set the addressability of an object. At present, the only supported identifier for MODEL-NAME ! is `small', indicating addressability via "small" (22-bit) ! addresses (so that their addresses can be loaded with the `addl' instruction). Caveat: such addressing is by definition not position independent and hence this attribute must not be used for objects defined by shared libraries. ! `ms_abi/sysv_abi' On 32-bit and 64-bit (i?86|x86_64)-*-* targets, you can use an ABI ! attribute to indicate which calling convention should be used for ! a function. The `ms_abi' attribute tells the compiler to use the ! Microsoft ABI, while the `sysv_abi' attribute tells the compiler ! to use the ABI used on GNU/Linux and other systems. The default ! is to use the Microsoft ABI when targeting Windows. On all other systems, the default is the x86/AMD ABI. ! Note, the `ms_abi' attribute for Microsoft Windows 64-bit targets ! currently requires the `-maccumulate-outgoing-args' option. - `callee_pop_aggregate_return (NUMBER)' On 32-bit i?86-*-* targets, you can use this attribute to control how aggregates are returned in memory. If the caller is responsible for popping the hidden pointer together with the rest of the arguments, specify NUMBER equal to zero. If callee is ! responsible for popping the hidden pointer, specify NUMBER equal ! to one. The default i386 ABI assumes that the callee pops the stack for hidden pointer. However, on 32-bit i386 Microsoft Windows targets, the compiler assumes that the caller pops the stack for hidden pointer. ! `ms_hook_prologue' ! On 32-bit i[34567]86-*-* targets and 64-bit x86_64-*-* targets, ! you can use this function attribute to make GCC generate the "hot-patching" function prologue used in Win32 API functions in Microsoft Windows XP Service Pack 2 and newer. ! `naked' Use this attribute on the ARM, AVR, MCORE, RX and SPU ports to indicate that the specified function does not need ! prologue/epilogue sequences generated by the compiler. It is up ! to the programmer to provide these sequences. The only statements ! that can be safely included in naked functions are `asm' ! statements that do not have operands. All other statements, ! including declarations of local variables, `if' statements, and so ! forth, should be avoided. Naked functions should be used to ! implement the body of an assembly function, while allowing the ! compiler to construct the requisite function declaration for the ! assembler. ! `near' ! On 68HC11 and 68HC12 the `near' attribute causes the compiler to ! use the normal calling convention based on `jsr' and `rts'. This ! attribute can be used to cancel the effect of the `-mlong-calls' option. On MeP targets this attribute causes the compiler to assume the called function is close enough to use the normal calling ! convention, overriding the `-mtf' command-line option. ! `nesting' ! Use this attribute together with `interrupt_handler', ! `exception_handler' or `nmi_handler' to indicate that the function entry code should enable nested interrupts or exceptions. ! `nmi_handler' Use this attribute on the Blackfin to indicate that the specified function is an NMI handler. The compiler generates function entry and exit sequences suitable for use in an NMI handler when this attribute is present. ! `no_instrument_function' ! If `-finstrument-functions' is given, profiling function calls are generated at entry and exit of most user-compiled functions. Functions with this attribute are not so instrumented. ! `no_split_stack' ! If `-fsplit-stack' is given, functions have a small prologue which decides whether to split the stack. Functions with the ! `no_split_stack' attribute do not have that prologue, and thus may run with only a small amount of stack space available. ! `noinline' This function attribute prevents a function from being considered for inlining.

On 32-bit and 64-bit (i?86|x86_64)-*-* targets, you can use an ABI ! attribute to indicate which calling convention should be used for a ! function. The 'ms_abi' attribute tells the compiler to use the ! Microsoft ABI, while the 'sysv_abi' attribute tells the compiler to ! use the ABI used on GNU/Linux and other systems. The default is to ! use the Microsoft ABI when targeting Windows. On all other systems, the default is the x86/AMD ABI. ! Note, the 'ms_abi' attribute for Microsoft Windows 64-bit targets ! currently requires the '-maccumulate-outgoing-args' option. ! ! 'callee_pop_aggregate_return (NUMBER)' On 32-bit i?86-*-* targets, you can use this attribute to control how aggregates are returned in memory. If the caller is responsible for popping the hidden pointer together with the rest of the arguments, specify NUMBER equal to zero. If callee is ! responsible for popping the hidden pointer, specify NUMBER equal to ! one. The default i386 ABI assumes that the callee pops the stack for hidden pointer. However, on 32-bit i386 Microsoft Windows targets, the compiler assumes that the caller pops the stack for hidden pointer. ! 'ms_hook_prologue' ! ! On 32-bit i[34567]86-*-* targets and 64-bit x86_64-*-* targets, you ! can use this function attribute to make GCC generate the "hot-patching" function prologue used in Win32 API functions in Microsoft Windows XP Service Pack 2 and newer. ! 'naked' Use this attribute on the ARM, AVR, MCORE, RX and SPU ports to indicate that the specified function does not need ! prologue/epilogue sequences generated by the compiler. It is up to ! the programmer to provide these sequences. The only statements ! that can be safely included in naked functions are 'asm' statements ! that do not have operands. All other statements, including ! declarations of local variables, 'if' statements, and so forth, ! should be avoided. Naked functions should be used to implement the ! body of an assembly function, while allowing the compiler to ! construct the requisite function declaration for the assembler. ! 'near' ! On 68HC11 and 68HC12 the 'near' attribute causes the compiler to ! use the normal calling convention based on 'jsr' and 'rts'. This ! attribute can be used to cancel the effect of the '-mlong-calls' option. On MeP targets this attribute causes the compiler to assume the called function is close enough to use the normal calling ! convention, overriding the '-mtf' command-line option. ! 'nesting' ! Use this attribute together with 'interrupt_handler', ! 'exception_handler' or 'nmi_handler' to indicate that the function entry code should enable nested interrupts or exceptions. ! 'nmi_handler' Use this attribute on the Blackfin to indicate that the specified function is an NMI handler. The compiler generates function entry and exit sequences suitable for use in an NMI handler when this attribute is present. ! 'no_instrument_function' ! If '-finstrument-functions' is given, profiling function calls are generated at entry and exit of most user-compiled functions. Functions with this attribute are not so instrumented. ! 'no_split_stack' ! If '-fsplit-stack' is given, functions have a small prologue which decides whether to split the stack. Functions with the ! 'no_split_stack' attribute do not have that prologue, and thus may run with only a small amount of stack space available. ! 'noinline' This function attribute prevents a function from being considered for inlining. If the function does not have side-effects, there are optimizations other than inlining that cause function calls to *************** attributes. *** 23019,23047 **** (*note Extended Asm::) in the called function, to serve as a special side-effect. ! `noclone' This function attribute prevents a function from being considered for cloning--a mechanism that produces specialized copies of functions and which is (currently) performed by interprocedural constant propagation. ! `nonnull (ARG-INDEX, ...)' ! The `nonnull' attribute specifies that some function parameters should be non-null pointers. For instance, the declaration: extern void * my_memcpy (void *dest, const void *src, size_t len) __attribute__((nonnull (1, 2))); ! causes the compiler to check that, in calls to `my_memcpy', arguments DEST and SRC are non-null. If the compiler determines that a null pointer is passed in an argument slot marked as ! non-null, and the `-Wnonnull' option is enabled, a warning is issued. The compiler may also choose to make optimizations based on the knowledge that certain function arguments will never be null. ! If no argument index list is given to the `nonnull' attribute, all pointer arguments are marked as non-null. To illustrate, the following declaration is equivalent to the previous example: --- 22855,22883 ---- (*note Extended Asm::) in the called function, to serve as a special side-effect. !

The AVR hardware globally disables interrupts when an interrupt is ! executed. Interrupt handler functions defined with the 'signal' attribute do not re-enable interrupts. It is save to enable ! interrupts in a 'signal' handler. This "save" only applies to the code generated by the compiler and not to the IRQ layout of the application which is responsibility of the application. ! If both 'signal' and 'interrupt' are specified for the same ! function, 'signal' is silently ignored. ! 'sp_switch' ! Use this attribute on the SH to indicate an 'interrupt_handler' function should switch to an alternate stack. It expects a string argument that names a global variable holding the address of the alternate stack. *************** attributes. *** 23392,23757 **** void f () __attribute__ ((interrupt_handler, sp_switch ("alt_stack"))); ! `stdcall' ! On the Intel 386, the `stdcall' attribute causes the compiler to assume that the called function pops off the stack space used to pass arguments, unless it takes a variable number of arguments. ! `syscall_linkage' This attribute is used to modify the IA-64 calling convention by marking all input registers as live at all function exits. This makes it possible to restart a system call after an interrupt without having to save/restore the input registers. This also prevents kernel data from leaking into application code. ! `target' ! The `target' attribute is used to specify that a function is to be compiled with different target options than specified on the command line. This can be used for instance to have functions compiled with a different ISA (instruction set architecture) than ! the default. You can also use the `#pragma GCC target' pragma to set more than one function to be compiled with specific target options. *Note Function Specific Option Pragmas::, for details ! about the `#pragma GCC target' pragma. For instance on a 386, you could compile one function with ! `target("sse4.1,arch=core2")' and another with ! `target("sse4a,arch=amdfam10")'. This is equivalent to compiling ! the first function with `-msse4.1' and `-march=core2' options, and ! the second function with `-msse4a' and `-march=amdfam10' options. It is up to the user to make sure that a function is only invoked on a machine that supports the particular ISA it is compiled for !

The ! `target("fpmath=sse,387")' option must be specified as ! `target("fpmath=sse+387")' because the comma would separate different options. On the PowerPC, the following options are allowed: ! `altivec' ! `no-altivec' Generate code that uses (does not use) AltiVec instructions.

In 32-bit code, you cannot enable VSX or AltiVec instructions ! unless `-mabi=altivec' is used on the command line. ! `friz' ! `no-friz' ! Generate (do not generate) the `friz' instruction when the ! `-funsafe-math-optimizations' option is used to optimize rounding a floating-point value to 64-bit integer and back to ! floating point. The `friz' instruction does not return the ! same value if the floating-point number is too large to fit ! in an integer. ! `avoid-indexed-addresses' ! `no-avoid-indexed-addresses' Generate code that tries to avoid (not avoid) the use of indexed load or store instructions. ! `paired' ! `no-paired' Generate code that uses (does not use) the generation of PAIRED simd instructions. ! `longcall' ! `no-longcall' Generate code that assumes (does not assume) that all calls are far away so that a longer more expensive calling sequence is required. ! `cpu=CPU' Specify the architecture to generate code for when compiling ! the function. If you select the `target("cpu=power7")' attribute when generating 32-bit code, VSX and AltiVec instructions are not generated unless you use the ! `-mabi=altivec' option on the command line. ! `tune=TUNE' Specify the architecture to tune for when compiling the ! function. If you do not specify the `target("tune=TUNE")' ! attribute and you do specify the `target("cpu=CPU")' ! attribute, compilation tunes for the CPU architecture, and ! not the default tuning specified on the command line. On the 386/x86_64 and PowerPC back ends, you can use either multiple strings to specify multiple options, or you can separate ! the option with a comma (`,'). On the 386/x86_64 and PowerPC back ends, the inliner does not inline a function that has different target options than the ! caller, unless the callee has a subset of the target options of ! the caller. For example a function declared with `target("sse3")' ! can inline a function with `target("sse2")', since `-msse3' ! implies `-msse2'. ! The `target' attribute is not implemented in GCC versions earlier ! than 4.4 for the i386/x86_64 and 4.6 for the PowerPC back ends. ! It is not currently implemented for other back ends. ! `tiny_data' Use this attribute on the H8/300H and H8S to indicate that the specified variable should be placed into the tiny data section. The compiler generates more efficient code for loads and stores on data in the tiny data section. Note the tiny data area is limited to slightly under 32KB of data. ! `trap_exit' ! Use this attribute on the SH for an `interrupt_handler' to return ! using `trapa' instead of `rte'. This attribute expects an integer argument specifying the trap number to be used. ! `trapa_handler' On SH targets this function attribute is similar to ! `interrupt_handler' but it does not save and restore all registers. ! `unused' This attribute, attached to a function, means that the function is meant to be possibly unused. GCC does not produce a warning for this function. ! `used' This attribute, attached to a function, means that code must be emitted for the function even if it appears that the function is not referenced. This is useful, for example, when the function is referenced only in inline assembly. When applied to a member function of a C++ class template, the ! attribute also means that the function is instantiated if the ! class itself is instantiated. ! `version_id' This IA-64 HP-UX attribute, attached to a global variable or function, renames a symbol to contain a version string, thus allowing for function level versioning.

If your linker is only able to align variables up to a maximum of 8-byte alignment, ! then specifying 'aligned(16)' in an '__attribute__' still only provides you with 8-byte alignment. See your linker documentation for further information. ! The 'aligned' attribute can also be used for functions (*note Function Attributes::.) ! 'cleanup (CLEANUP_FUNCTION)' ! The 'cleanup' attribute runs a function when the variable goes out of scope. This attribute can only be applied to auto function scope variables; it may not be applied to parameters or variables with static storage duration. The function must take one parameter, a pointer to a type compatible with the variable. The return value of the function (if any) is ignored. ! If '-fexceptions' is enabled, then CLEANUP_FUNCTION is run during the stack unwinding that happens during the processing of the ! exception. Note that the 'cleanup' attribute does not allow the ! exception to be caught, only to perform an action. It is undefined ! what happens if CLEANUP_FUNCTION does not return normally. ! 'common' ! 'nocommon' ! The 'common' attribute requests GCC to place a variable in "common" ! storage. The 'nocommon' attribute requests the opposite--to ! allocate space for it directly. ! These attributes override the default chosen by the '-fno-common' ! and '-fcommon' flags respectively. ! 'deprecated' ! 'deprecated (MSG)' ! The 'deprecated' attribute results in a warning if the variable is used anywhere in the source file. This is useful when identifying variables that are expected to be removed in a future version of a program. The warning also includes the location of the declaration *************** attributes. *** 24362,24389 **** argument, which must be a string, is printed in the warning if present. ! The `deprecated' attribute can also be used for functions and ! types (*note Function Attributes::, *note Type Attributes::.) ! `mode (MODE)' This attribute specifies the data type for the declaration--whichever type corresponds to the mode MODE. This in ! effect lets you request an integer or floating-point type ! according to its width. ! You may also specify a mode of `byte' or `__byte__' to indicate ! the mode corresponding to a one-byte integer, `word' or `__word__' ! for the mode of a one-word integer, and `pointer' or `__pointer__' ! for the mode used to represent pointers. ! `packed' ! The `packed' attribute specifies that a variable or structure field should have the smallest possible alignment--one byte for a variable, and one bit for a field, unless you specify a larger ! value with the `aligned' attribute. !

'transparent_union', 'unused', 'deprecated', 'visibility', and ! 'may_alias'. Other attributes are defined for functions (*note Function ! Attributes::) and for variables (*note Variable Attributes::). ! You may also specify any one of these attributes with '__' preceding and following its keyword. This allows you to use these attributes in header files without being concerned about a possible macro of the same ! name. For example, you may use '__aligned__' instead of 'aligned'. You may specify type attributes in an enum, struct or union type ! declaration or definition, or for other types in a 'typedef' declaration.

For example, on many targets there is a system register that can be set to control the rounding mode of floating-point operations. You might try setting it with a volatile ! 'asm', like this PowerPC example: asm volatile("mtfsf 255,%0" : : "f" (fpenv)); sum = x + y; This does not work reliably, as the compiler may move the addition back ! before the volatile 'asm'. To make it work you need to add an ! artificial dependency to the 'asm' referencing a variable in the code you don't want moved, for example: asm volatile ("mtfsf 255,%1" : "=X"(sum): "f"(fpenv)); sum = x + y; ! Similarly, you can't expect a sequence of volatile 'asm' instructions to remain perfectly consecutive. If you want consecutive output, use a ! single 'asm'. Also, GCC performs some optimizations across a volatile ! 'asm' instruction; GCC does not "forget everything" when it encounters a ! volatile 'asm' instruction the way some other compilers do. ! An 'asm' instruction without any output operands is treated identically ! to a volatile 'asm' instruction. It is a natural idea to look for a way to give access to the condition code left by the assembler instruction. However, when we attempted to implement this, we found no way to make it work reliably. The problem ! is that output operands might need reloading, which result in additional ! following "store" instructions. On most machines, these instructions ! alter the condition code before there is time to test it. This problem ! doesn't arise for ordinary "test" and "compare" instructions because ! they don't have any output operands. For reasons similar to those described above, it is not possible to give an assembler instruction access to the condition code left by previous instructions. ! As of GCC version 4.5, 'asm goto' may be used to have the assembly jump ! to one or more C labels. In this form, a fifth section after the clobber list contains a list of all C labels to which the assembly may ! jump. Each label operand is implicitly self-named. The 'asm' is also assumed to fall through to the next statement. ! This form of 'asm' is restricted to not have outputs. This is due to a ! internal restriction in the compiler that control transfer instructions ! cannot have outputs. This restriction on 'asm goto' may be lifted in ! some future version of the compiler. In the meantime, 'asm goto' may ! include a memory clobber, and so leave outputs in memory. int frob(int x) { *************** be lifted in some future version of the *** 25739,25749 **** return -1; } !

In constraints with multiple alternatives, sometimes one alternative ! requires '&' while others do not. See, for example, the 'movdf' insn of the 68000. An input operand can be tied to an earlyclobber operand if its only use as an input occurs before the early result is written. Adding alternatives of this form often allows GCC to produce better code when only some of the inputs can be affected by the earlyclobber. ! See, for example, the 'mulsi3' insn of the ARM. ! '&' does not obviate the need to write '='. ! '%' Declares the instruction to be commutative for this operand and the following operand. This means that the compiler may interchange the two operands if that is the cheapest way to make all operands fit the constraints. GCC can only handle one commutative pair in ! an asm; if you use more, the compiler may fail. Note that you need ! not use the modifier if the two alternatives are strictly identical; this would only waste time in the reload pass. The modifier is not operational after register allocation, so the ! result of 'define_peephole2' and 'define_split's performed after ! reload cannot rely on '%' to make the intended insn match. ! '#' Says that all following characters, up to the next comma, are to be ignored as a constraint. They are significant only for choosing register preferences. ! '*' Says that the following character should be ignored when choosing ! register preferences. '*' has no effect on the meaning of the constraint as a constraint, and no effect on reloading. For LRA ! '*' additionally disparages slightly the alternative if the following character matches the operand.

The ellipsis is for exactly one floating-point value to classify. GCC treats the last argument as type-generic, which means it does not do default promotion from float to double. -- Built-in Function: double __builtin_inf (void) ! Similar to '__builtin_huge_val', except a warning is generated if the target floating-point format does not support infinities. -- Built-in Function: _Decimal32 __builtin_infd32 (void) !

Similar to 'isinf', except the return value is negative for an ! argument of '-Inf'. Note while the parameter list is an ellipsis, this function only accepts exactly one floating-point argument. GCC treats this parameter as type-generic, which means it does not do default promotion from float to double. -- Built-in Function: double __builtin_nan (const char *str) ! This is an implementation of the ISO C99 function 'nan'. ! Since ISO C99 defines this function in terms of 'strtod', which we do not implement, a description of the parsing is in order. The ! string is parsed as by 'strtol'; that is, the base is recognized by ! leading '0' or '0x' prefixes. The number parsed is placed in the ! significand such that the least significant bit of the number is at ! the least significant bit of the significand. The number is truncated to fit the significand field provided. The significand is forced to be a quiet NaN. This function, if given a string literal all of which would have ! been consumed by 'strtol', is evaluated early enough that it is considered a compile-time constant. -- Built-in Function: _Decimal32 __builtin_nand32 (const char *str) !

These built-in functions are available for the i386 and x86-64 family ! of computers, depending on the command-line switches used. ! If you specify command-line switches such as `-msse', the compiler could use the extended instruction sets even if the built-ins are not used explicitly in the program. For this reason, applications that perform run-time CPU detection must compile separate files for each ! supported architecture, using the appropriate flags.

Both kinds of support are enabled by the ! '-mpaired-single' command-line option. The vector type associated with paired-single values is usually called ! 'v2sf'. It can be defined in C as follows: typedef float v2sf __attribute__ ((vector_size (8))); ! 'v2sf' values are initialized in the same way as aggregates.

Generates the 'tbegin' machine instruction starting a ! non-constraint hardware transaction. If the parameter is non-NULL ! the memory area is used to store the transaction diagnostic buffer ! and will be passed as first operand to 'tbegin'. This buffer can ! be defined using the 'struct __htm_tdb' C struct defined in ! 'htmintrin.h' and must reside on a double-word boundary. The ! second tbegin operand is set to '0xff0c'. This enables ! save/restore of all GPRs and disables aborts for FPR and AR ! manipulations inside the transaction body. The condition code set ! by the tbegin instruction is returned as integer value. The tbegin ! instruction by definition overwrites the content of all FPRs. The ! compiler will generate code which saves and restores the FPRs. For ! soft-float code it is recommended to used the '*_nofloat' variant. ! In order to prevent a TDB from being written it is required to pass ! an constant zero value as parameter. Passing the zero value ! through a variable is not sufficient. Although modifications of ! access registers inside the transaction will not trigger an ! transaction abort it is not supported to actually modify them. ! Access registers do not get saved when entering a transaction. ! They will have undefined state when reaching the abort code. ! ! Macros for the possible return codes of tbegin are defined in the !

To configure the hook, you set the global variable ! `__objc_msg_forward2' to a function with the same argument and return ! types of `objc_msg_lookup()'. When `objc_msg_lookup()' can not find a method implementation, it invokes the hook function you provided to get a method implementation to return. So, in practice ! `__objc_msg_forward2' allows you to extend `objc_msg_lookup()' by ! adding some custom code that is called to do a further lookup when no ! standard method implementation can be found using the normal lookup. This hook is generally reserved for "Foundation" libraries such as GNUstep Base, which use it to implement their high-level method ! forwarding API, typically based around the `forwardInvocation:' method. So, unless you are implementing your own "Foundation" library, you should not set this hook. ! In a typical forwarding implementation, the `__objc_msg_forward2' hook function determines the argument and return type of the method that is being looked up, and then creates a function that takes these arguments and has that return type, and returns it to the caller. Creating this function is non-trivial and is typically performed using a dedicated ! library such as `libffi'. The forwarding method implementation thus created is returned by ! `objc_msg_lookup()' and is executed as if it was a normal method ! implementation. When the forwarding method implementation is called, ! it is usually expected to pack all arguments into some sort of object ! (typically, an `NSInvocation' in a "Foundation" library), and hand it ! over to the programmer (`forwardInvocation:') who is then allowed to manipulate the method invocation using a high-level API provided by the "Foundation" library. For example, the programmer may want to examine the method invocation arguments and name and potentially change them before forwarding the method invocation to one or more local objects ! (`performInvocation:') or even to remote objects (by using Distributed Objects or some other mechanism). When all this completes, the return value is passed back and must be returned correctly to the original caller. ! Note that the GNU Objective-C runtime currently provides no support ! for method forwarding or method invocations other than the ! `__objc_msg_forward2' hook. ! If the forwarding hook does not exist or returns `NULL', the runtime currently attempts forwarding using an older, deprecated API, and if that fails, it aborts the program.

Modifying GCC sources requires additional tools described below. Tools/packages necessary for building GCC *************** ISO C++98 compiler *** 125,356 **** C compiler. To build all languages in a cross-compiler or other configuration ! where 3-stage bootstrap is not performed, you need to start with ! an existing GCC binary (version 3.4 or later) because source code ! for language frontends other than C might use GCC extensions. Note that to bootstrap GCC with versions of GCC earlier than 3.4, ! you may need to use `--disable-stage1-checking', though bootstrapping the compiler with such earlier compilers is strongly discouraged. GNAT In order to build the Ada compiler (GNAT) you must already have GNAT installed because portions of the Ada frontend are written in Ada (with GNAT extensions.) Refer to the Ada installation instructions for more specific information. A "working" POSIX compatible shell, or GNU bash ! Necessary when running `configure' because some `/bin/sh' shells have bugs and may crash when configuring the target libraries. In ! other cases, `/bin/sh' or `ksh' have disastrous corner-case ! performance problems. This can cause target `configure' runs to literally take days to complete in some cases. ! So on some platforms `/bin/ksh' is sufficient, on others it isn't. ! See the host/target specific instructions for your platform, or ! use `bash' to be sure. Then set `CONFIG_SHELL' in your ! environment to your "good" shell prior to running ! `configure'/`make'. ! `zsh' is not a fully compliant POSIX shell and will not work when configuring GCC. A POSIX or SVR4 awk Necessary for creating some of the generated source files for GCC. If in doubt, use a recent GNU awk version, as some of the older ones are broken. GNU awk version 3.1.5 is known to work. GNU binutils Necessary in some circumstances, optional in others. See the host/target specific instructions for your platform for the exact requirements. gzip version 1.2.4 (or later) or bzip2 version 1.0.2 (or later) ! Necessary to uncompress GCC `tar' files when source code is obtained via FTP mirror sites. GNU make version 3.80 (or later) You must have GNU make installed to build GCC. GNU tar version 1.14 (or later) Necessary (only on some platforms) to untar the source code. Many ! systems' `tar' programs will also work, only try GNU `tar' if you have problems. Perl version 5.6.1 (or later) - Necessary when targeting Darwin, building `libstdc++', and not - using `--disable-symvers'. Necessary when targeting Solaris 2 - with Sun `ld' and not using `--disable-symvers'. The bundled - `perl' in Solaris 8 and up works. ! Necessary when regenerating `Makefile' dependencies in libiberty. ! Necessary when regenerating `libiberty/functions.texi'. Necessary when generating manpages from Texinfo manuals. Used by various scripts to generate some files included in SVN (mainly Unicode-related and rarely changing) from source tables. ! `jar', or InfoZIP (`zip' and `unzip') ! Necessary to build libgcj, the GCJ runtime. Several support libraries are necessary to build GCC, some are required, others optional. While any sufficiently new version of required tools usually work, library requirements are generally stricter. Newer versions may work in some cases, but it's safer to use ! the exact versions documented. We appreciate bug reports about ! problems with newer versions, though. If your OS vendor provides ! packages for the support libraries then using those packages may be the ! simplest way to install the libraries. GNU Multiple Precision Library (GMP) version 4.3.2 (or later) Necessary to build GCC. If a GMP source distribution is found in a ! subdirectory of your GCC sources named `gmp', it will be built ! together with GCC. Alternatively, if GMP is already installed but it is not in your library search path, you will have to configure ! with the `--with-gmp' configure option. See also `--with-gmp-lib' ! and `--with-gmp-include'. MPFR Library version 2.4.2 (or later) Necessary to build GCC. It can be downloaded from ! `http://www.mpfr.org/'. If an MPFR source distribution is found ! in a subdirectory of your GCC sources named `mpfr', it will be ! built together with GCC. Alternatively, if MPFR is already ! installed but it is not in your default library search path, the ! `--with-mpfr' configure option should be used. See also ! `--with-mpfr-lib' and `--with-mpfr-include'. MPC Library version 0.8.1 (or later) Necessary to build GCC. It can be downloaded from ! `http://www.multiprecision.org/'. If an MPC source distribution ! is found in a subdirectory of your GCC sources named `mpc', it ! will be built together with GCC. Alternatively, if MPC is already ! installed but it is not in your default library search path, the ! `--with-mpc' configure option should be used. See also ! `--with-mpc-lib' and `--with-mpc-include'. ISL Library version 0.11.1 Necessary to build GCC with the Graphite loop optimizations. It ! can be downloaded from `ftp://gcc.gnu.org/pub/gcc/infrastructure/' ! as `isl-0.11.1.tar.bz2'. ! The `--with-isl' configure option should be used if ISL is not installed in your default library search path. CLooG 0.18.0 Necessary to build GCC with the Graphite loop optimizations. It ! can be downloaded from `ftp://gcc.gnu.org/pub/gcc/infrastructure/' ! as `cloog-0.18.0.tar.gz'. The `--with-cloog' configure option should be used if CLooG is not installed in your default library search path. CLooG needs to be built against ISL 0.11.1. Use ! `--with-isl=system' to direct CLooG to pick up an already ! installed ISL, otherwise it will use ISL 0.11.1 as bundled with ! CLooG. CLooG needs to be configured to use GMP internally, use ! `--with-bits=gmp' to direct it to do that. ! Tools/packages necessary for modifying GCC ========================================== autoconf version 2.64 GNU m4 version 1.4.6 (or later) ! Necessary when modifying `configure.ac', `aclocal.m4', etc. to ! regenerate `configure' and `config.in' files. automake version 1.11.1 ! Necessary when modifying a `Makefile.am' file to regenerate its ! associated `Makefile.in'. Much of GCC does not use automake, so directly edit the ! `Makefile.in' file. Specifically this applies to the `gcc', ! `intl', `libcpp', `libiberty', `libobjc' directories as well as ! any of their subdirectories. For directories that use automake, GCC requires the latest release ! in the 1.11 series, which is currently 1.11.1. When regenerating ! a directory to a newer version, please update all the directories using an older 1.11 to the latest released version. gettext version 0.14.5 (or later) ! Needed to regenerate `gcc.pot'. gperf version 2.7.2 (or later) ! Necessary when modifying `gperf' input files, e.g. ! `gcc/cp/cfns.gperf' to regenerate its associated header file, e.g. ! `gcc/cp/cfns.h'. DejaGnu 1.4.4 Expect Tcl Necessary to run the GCC testsuite; see the section on testing for details. autogen version 5.5.4 (or later) and guile version 1.4.1 (or later) - Necessary to regenerate `fixinc/fixincl.x' from - `fixinc/inclhack.def' and `fixinc/*.tpl'. ! Necessary to run `make check' for `fixinc'. ! Necessary to regenerate the top level `Makefile.in' file from ! `Makefile.tpl' and `Makefile.def'. Flex version 2.5.4 (or later) ! Necessary when modifying `*.l' files. Necessary to build GCC during development because the generated output files are not included in the SVN repository. They are included in releases. Texinfo version 4.7 (or later) ! Necessary for running `makeinfo' when modifying `*.texi' files to test your changes. ! Necessary for running `make dvi' or `make pdf' to create printable documentation in DVI or PDF format. Texinfo version 4.8 or later ! is required for `make pdf'. Necessary to build GCC documentation during development because the generated output files are not included in the SVN repository. They are included in releases. TeX (any working version) ! Necessary for running `texi2dvi' and `texi2pdf', which are used ! when running `make dvi' or `make pdf' to create DVI or PDF files, respectively. SVN (any version) SSH (any version) Necessary to access the SVN repository. Public releases and weekly snapshots of the development sources are also available via FTP. GNU diffutils version 2.7 (or later) Useful when submitting patches for the GCC source code. patch version 2.5.4 (or later) ! Necessary when applying patches, created with `diff', to one's own sources. ecj1 gjavah ! If you wish to modify `.java' files in libjava, you will need to ! configure with `--enable-java-maintainer-mode', and you will need ! to have executables named `ecj1' and `gjavah' in your path. The ! `ecj1' executable should run the Eclipse Java compiler via the GCC-specific entry point. You can download a suitable jar from ! `ftp://sourceware.org/pub/java/', or by running the script ! `contrib/download_ecj'. antlr.jar version 2.7.1 (or later) antlr binary - If you wish to build the `gjdoc' binary in libjava, you will need - to have an `antlr.jar' library available. The library is searched - for in system locations but can be specified with - `--with-antlr-jar=' instead. When configuring with - `--enable-java-maintainer-mode', you will need to have one of the - executables named `cantlr', `runantlr' or `antlr' in your path.

LIBEXEC defaults to ! `EXEC-PREFIX/libexec'; EXEC-PREFIX defaults to PREFIX, which ! defaults to `/usr/local' unless overridden by the ! `--prefix=PATHNAME' switch described above. TARGET is the ! target system triple, such as `sparc-sun-solaris2.7', and VERSION denotes the GCC version, such as 3.0. * If the target system is the same that you are building on, check operating system specific directories (e.g. ! `/usr/ccs/bin' on Sun Solaris 2). ! * Check in the `PATH' for a tool whose name is prefixed by the target system triple. ! * Check in the `PATH' for a tool whose name is not prefixed by ! the target system triple, if the host and target system ! triple are the same (in other words, we use a host tool if it ! can be used for the target as well). ! You may want to use `--with-as' if no assembler is installed in ! the directories listed above, or if you have multiple assemblers installed and want to choose one that is not found by the above rules. ! `--with-gnu-ld' ! Same as `--with-gnu-as' but for the linker. ! `--with-ld=PATHNAME' ! Same as `--with-as' but for the linker. ! `--with-stabs' Specify that stabs debugging information should be used instead of ! whatever format the host normally uses. Normally GCC uses the ! same debug format as the host system. On MIPS based systems and on Alphas, you must specify whether you want GCC to create the normal ECOFF debugging format, or to use BSD-style stabs passed through the ECOFF symbol table. The normal ! ECOFF debug format cannot fully handle languages other than C. ! BSD stabs format can handle other languages, but it only works ! with the GNU debugger GDB. Normally, GCC uses the ECOFF debugging format by default; if you ! prefer BSD stabs, specify `--with-stabs' when you configure GCC.

Use '--disable-shared' to build only static libraries. Note that ! '--disable-shared' does not accept a list of package names as ! argument, only '--enable-shared' does. ! '--with-gnu-as' ! Specify that the compiler should assume that the assembler it finds ! is the GNU assembler. However, this does not modify the rules to ! find an assembler and will result in confusion if the assembler ! found is not actually the GNU assembler. (Confusion may also ! result if the compiler finds the GNU assembler but has not been ! configured with '--with-gnu-as'.) If you have more than one ! assembler installed on your system, you may want to use this option ! in connection with '--with-as=PATHNAME' or ! '--with-build-time-tools=PATHNAME'.

'--with-stabs' Specify that stabs debugging information should be used instead of ! whatever format the host normally uses. Normally GCC uses the same ! debug format as the host system. On MIPS based systems and on Alphas, you must specify whether you want GCC to create the normal ECOFF debugging format, or to use BSD-style stabs passed through the ECOFF symbol table. The normal ! ECOFF debug format cannot fully handle languages other than C. BSD ! stabs format can handle other languages, but it only works with the ! GNU debugger GDB.

In addition, 'libstdc++''s include files will be installed into ! 'LIBDIR' unless you overruled it by using ! '--with-gxx-include-dir=DIRNAME'. Using this option is particularly useful if you intend to use several versions of GCC in ! parallel. This is currently supported by 'libgfortran', 'libjava', ! 'libmudflap', 'libstdc++', and 'libobjc'. ! '--enable-languages=LANG1,LANG2,...' Specify that only a particular subset of compilers and their runtime libraries should be built. For a list of valid values for ! LANGN you can issue the following command in the 'gcc' directory of ! your GCC source tree: grep language= */config-lang.in ! Currently, you can use any of the following: 'all', 'ada', 'c', ! 'c++', 'fortran', 'go', 'java', 'objc', 'obj-c++'. Building the Ada compiler has special requirements, see below. If you do not ! pass this flag, or specify the option 'all', then all default ! languages available in the 'gcc' sub-tree will be configured. Ada, ! Go and Objective-C++ are not default languages; the rest are. ! '--enable-stage1-languages=LANG1,LANG2,...' Specify that a particular subset of compilers and their runtime ! libraries should be built with the system C compiler during stage 1 ! of the bootstrap process, rather than only in later stages with the ! bootstrapped C compiler. The list of valid values is the same as ! for '--enable-languages', and the option 'all' will select all of ! the languages enabled by '--enable-languages'. This option is primarily useful for GCC development; for instance, when a development version of the compiler cannot bootstrap due to ! compiler bugs, or when one is debugging front ends other than the C ! front end. When this option is used, one can then build the target ! libraries for the specified languages with the stage-1 compiler by ! using 'make stage1-bubble all-target', or run the testsuite on the ! stage-1 compiler for the specified languages using 'make ! stage1-start check-gcc'. ! '--disable-libada' Specify that the run-time libraries and tools used by GNAT should not be built. This can be useful for debugging, or for compatibility with previous Ada build procedures, when it was ! required to explicitly do a 'make -C gcc gnatlib_and_tools'. ! '--disable-libssp' Specify that the run-time libraries for stack smashing protection should not be built. ! '--disable-libquadmath' Specify that the GCC quad-precision math library should not be built. On some systems, the library is required to be linkable when building the Fortran front end, unless ! '--disable-libquadmath-support' is used. ! '--disable-libquadmath-support' ! Specify that the Fortran front end and 'libgfortran' do not add ! support for 'libquadmath' on systems supporting it. ! '--disable-libgomp' Specify that the run-time libraries used by GOMP should not be built. ! '--with-dwarf2' Specify that the compiler should use DWARF 2 debugging information as the default. ! '--enable-targets=all' ! '--enable-targets=TARGET_LIST' Some GCC targets, e.g. powerpc64-linux, build bi-arch compilers. These are compilers that are able to generate either 64-bit or 32-bit code. Typically, the corresponding 32-bit target, e.g. *************** option. *** 1194,1855 **** affects sparc-linux, powerpc-linux, x86-linux, mips-linux and s390-linux. ! `--enable-secureplt' ! This option enables `-msecure-plt' by default for powerpc-linux. *Note RS/6000 and PowerPC Options: (gcc)RS/6000 and PowerPC Options, ! `--enable-cld' ! This option enables `-mcld' by default for 32-bit x86 targets. *Note i386 and x86-64 Options: (gcc)i386 and x86-64 Options, ! `--enable-win32-registry' ! `--enable-win32-registry=KEY' ! `--disable-win32-registry' ! The `--enable-win32-registry' option enables Microsoft Windows-hosted GCC to look up installations paths in the registry using the following key: ! `HKEY_LOCAL_MACHINE\SOFTWARE\Free Software Foundation\KEY' KEY defaults to GCC version number, and can be overridden by the ! `--enable-win32-registry=KEY' option. Vendors and distributors ! who use custom installers are encouraged to provide a different ! key, perhaps one comprised of vendor name and GCC version number, ! to avoid conflict with existing installations. This feature is enabled by default, and can be disabled by ! `--disable-win32-registry' option. This option has no effect on the other hosts. ! `--nfp' Specify that the machine does not have a floating point unit. This ! option only applies to `m68k-sun-sunosN'. On any other system, ! `--nfp' has no effect. ! `--enable-werror' ! `--disable-werror' ! `--enable-werror=yes' ! `--enable-werror=no' When you specify this option, it controls whether certain files in ! the compiler are built with `-Werror' in bootstrap stage2 and ! later. If you don't specify it, `-Werror' is turned on for the main development trunk. However it defaults to off for release branches and final releases. The specific files which get ! `-Werror' are controlled by the Makefiles. ! `--enable-checking' ! `--enable-checking=LIST' When you specify this option, the compiler is built to perform ! internal consistency checks of the requested complexity. This ! does not change the generated code, but adds error checking within ! the compiler. This will slow down the compiler and may only work ! properly if you are building the compiler with GCC. This is `yes' ! by default when building from SVN or snapshots, but `release' for ! releases. The default for building the stage1 compiler is `yes'. More control over the checks may be had by specifying LIST. The ! categories of checks available are `yes' (most common checks ! `assert,misc,tree,gc,rtlflag,runtime'), `no' (no checks at all), ! `all' (all but `valgrind'), `release' (cheapest checks ! `assert,runtime') or `none' (same as `no'). Individual checks can ! be enabled with these flags `assert', `df', `fold', `gc', `gcac' ! `misc', `rtl', `rtlflag', `runtime', `tree', and `valgrind'. ! The `valgrind' check requires the external `valgrind' simulator, ! available from `http://valgrind.org/'. The `df', `rtl', `gcac' ! and `valgrind' checks are very expensive. To disable all ! checking, `--disable-checking' or `--enable-checking=none' must be ! explicitly requested. Disabling assertions will make the compiler ! and runtime slightly faster but increase the risk of undetected ! internal errors causing wrong code to be generated. ! `--disable-stage1-checking' ! `--enable-stage1-checking' ! `--enable-stage1-checking=LIST' ! If no `--enable-checking' option is specified the stage1 compiler ! will be built with `yes' checking enabled, otherwise the stage1 ! checking flags are the same as specified by `--enable-checking'. To build the stage1 compiler with different checking options use ! `--enable-stage1-checking'. The list of checking options is the ! same as for `--enable-checking'. If your system is too slow or ! too small to bootstrap a released compiler with checking for ! stage1 enabled, you can use `--disable-stage1-checking' to disable checking for the stage1 compiler. ! `--enable-coverage' ! `--enable-coverage=LEVEL' With this option, the compiler is built to collect self coverage information, every time it is run. This is for internal development purposes, and only works when the compiler is being built with gcc. The LEVEL argument controls whether the compiler ! is built optimized or not, values are `opt' and `noopt'. For ! coverage analysis you want to disable optimization, for ! performance analysis you want to enable optimization. When ! coverage is enabled, the default level is without optimization. ! `--enable-gather-detailed-mem-stats' When this option is specified more detailed information on memory allocation is gathered. This information is printed when using ! `-fmem-report'. ! `--enable-nls' ! `--disable-nls' ! The `--enable-nls' option enables Native Language Support (NLS), which lets GCC output diagnostics in languages other than American English. Native Language Support is enabled by default if not ! doing a canadian cross build. The `--disable-nls' option disables NLS. ! `--with-included-gettext' ! If NLS is enabled, the `--with-included-gettext' option causes the ! build procedure to prefer its copy of GNU `gettext'. ! `--with-catgets' ! If NLS is enabled, and if the host lacks `gettext' but has the ! inferior `catgets' interface, the GCC build procedure normally ! ignores `catgets' and instead uses GCC's copy of the GNU `gettext' ! library. The `--with-catgets' option causes the build procedure ! to use the host's `catgets' in this situation. ! `--with-libiconv-prefix=DIR' ! Search for libiconv header files in `DIR/include' and libiconv ! library files in `DIR/lib'. ! `--enable-obsolete' Enable configuration for an obsoleted system. If you attempt to configure GCC for a system (build, host, or target) which has been obsoleted, and you do not specify this flag, configure will halt with an error message. ! All support for systems which have been obsoleted in one release ! of GCC is removed entirely in the next major release, unless ! someone steps forward to maintain the port. ! `--enable-decimal-float' ! `--enable-decimal-float=yes' ! `--enable-decimal-float=no' ! `--enable-decimal-float=bid' ! `--enable-decimal-float=dpd' ! `--disable-decimal-float' Enable (or disable) support for the C decimal floating point extension that is in the IEEE 754-2008 standard. This is enabled by default only on PowerPC, i386, and x86_64 GNU/Linux systems. Other systems may also support it, but require the user to specifically enable it. You can optionally control which decimal ! floating point format is used (either `bid' or `dpd'). The `bid' (binary integer decimal) format is default on i386 and x86_64 ! systems, and the `dpd' (densely packed decimal) format is default on PowerPC systems. ! `--enable-fixed-point' ! `--disable-fixed-point' Enable (or disable) support for C fixed-point arithmetic. This option is enabled by default for some targets (such as MIPS) which have hardware-support for fixed-point operations. On other targets, you may enable this option manually. ! `--with-long-double-128' ! Specify if `long double' type should be 128-bit by default on selected GNU/Linux architectures. If using ! `--without-long-double-128', `long double' will be by default ! 64-bit, the same as `double' type. When neither of these ! configure options are used, the default will be 128-bit `long ! double' when built against GNU C Library 2.4 and later, 64-bit ! `long double' otherwise. ! `--with-gmp=PATHNAME' ! `--with-gmp-include=PATHNAME' ! `--with-gmp-lib=PATHNAME' ! `--with-mpfr=PATHNAME' ! `--with-mpfr-include=PATHNAME' ! `--with-mpfr-lib=PATHNAME' ! `--with-mpc=PATHNAME' ! `--with-mpc-include=PATHNAME' ! `--with-mpc-lib=PATHNAME' If you want to build GCC but do not have the GMP library, the MPFR library and/or the MPC library installed in a standard location and do not have their sources present in the GCC source tree then you can explicitly specify the directory where they are installed ! (`--with-gmp=GMPINSTALLDIR', `--with-mpfr=MPFRINSTALLDIR', ! `--with-mpc=MPCINSTALLDIR'). The `--with-gmp=GMPINSTALLDIR' ! option is shorthand for `--with-gmp-lib=GMPINSTALLDIR/lib' and ! `--with-gmp-include=GMPINSTALLDIR/include'. Likewise the ! `--with-mpfr=MPFRINSTALLDIR' option is shorthand for ! `--with-mpfr-lib=MPFRINSTALLDIR/lib' and ! `--with-mpfr-include=MPFRINSTALLDIR/include', also the ! `--with-mpc=MPCINSTALLDIR' option is shorthand for ! `--with-mpc-lib=MPCINSTALLDIR/lib' and ! `--with-mpc-include=MPCINSTALLDIR/include'. If these shorthand assumptions are not correct, you can use the explicit include and lib options directly. You might also need to ensure the shared libraries can be found by the dynamic linker when building and using GCC, for example by setting the runtime shared library path ! variable (`LD_LIBRARY_PATH' on GNU/Linux and Solaris systems). These flags are applicable to the host platform only. When building a cross compiler, they will not be used to configure target libraries. ! `--with-isl=PATHNAME' ! `--with-isl-include=PATHNAME' ! `--with-isl-lib=PATHNAME' ! `--with-cloog=PATHNAME' ! `--with-cloog-include=PATHNAME' ! `--with-cloog-lib=PATHNAME' If you do not have ISL and the CLooG libraries installed in a standard location and you want to build GCC, you can explicitly specify the directory where they are installed ! (`--with-isl=ISLINSTALLDIR', `--with-cloog=CLOOGINSTALLDIR'). The ! `--with-isl=ISLINSTALLDIR' option is shorthand for ! `--with-isl-lib=ISLINSTALLDIR/lib' and ! `--with-isl-include=ISLINSTALLDIR/include'. Likewise the ! `--with-cloog=CLOOGINSTALLDIR' option is shorthand for ! `--with-cloog-lib=CLOOGINSTALLDIR/lib' and ! `--with-cloog-include=CLOOGINSTALLDIR/include'. If these ! shorthand assumptions are not correct, you can use the explicit ! include and lib options directly. These flags are applicable to the host platform only. When building a cross compiler, they will not be used to configure target libraries. ! `--with-host-libstdcxx=LINKER-ARGS' If you are linking with a static copy of PPL, you can use this option to specify how the linker should find the standard C++ ! library used internally by PPL. Typical values of LINKER-ARGS ! might be `-lstdc++' or `-Wl,-Bstatic,-lstdc++,-Bdynamic -lm'. If ! you are linking with a shared copy of PPL, you probably do not ! need this option; shared library dependencies will cause the ! linker to search for the standard C++ library automatically. ! `--with-stage1-ldflags=FLAGS' This option may be used to set linker flags to be used when linking ! stage 1 of GCC. These are also used when linking GCC if ! configured with `--disable-bootstrap'. By default no special ! flags are used. ! `--with-stage1-libs=LIBS' This option may be used to set libraries to be used when linking ! stage 1 of GCC. These are also used when linking GCC if ! configured with `--disable-bootstrap'. The default is the ! argument to `--with-host-libstdcxx', if specified. ! `--with-boot-ldflags=FLAGS' This option may be used to set linker flags to be used when linking ! stage 2 and later when bootstrapping GCC. If neither -with-boot-libs nor -with-host-libstdcxx is set to a value, then ! the default is `-static-libstdc++ -static-libgcc'. ! `--with-boot-libs=LIBS' This option may be used to set libraries to be used when linking ! stage 2 and later when bootstrapping GCC. The default is the ! argument to `--with-host-libstdcxx', if specified. ! `--with-debug-prefix-map=MAP' ! Convert source directory names using `-fdebug-prefix-map' when ! building runtime libraries. `MAP' is a space-separated list of ! maps of the form `OLD=NEW'. ! `--enable-linker-build-id' ! Tells GCC to pass `--build-id' option to the linker for all final ! links (links performed without the `-r' or `--relocatable' ! option), if the linker supports it. If you specify ! `--enable-linker-build-id', but your linker does not support ! `--build-id' option, a warning is issued and the ! `--enable-linker-build-id' option is ignored. The default is off. ! `--with-linker-hash-style=CHOICE' ! Tells GCC to pass `--hash-style=CHOICE' option to the linker for ! all final links. CHOICE can be one of `sysv', `gnu', and `both' ! where `sysv' is the default. ! `--enable-gnu-unique-object' ! `--disable-gnu-unique-object' Tells GCC to use the gnu_unique_object relocation for C++ template static data members and inline function local statics. Enabled by default for a native toolchain with an assembler that accepts it and GLIBC 2.11 or above, otherwise disabled. ! `--enable-lto' ! `--disable-lto' ! Enable support for link-time optimization (LTO). This is enabled ! by default, and may be disabled using `--disable-lto'. ! `--with-plugin-ld=PATHNAME' Enable an alternate linker to be used at link-time optimization ! (LTO) link time when `-fuse-linker-plugin' is enabled. This ! linker should have plugin support such as gold starting with ! version 2.20 or GNU ld starting with version 2.21. See ! `-fuse-linker-plugin' for details. ! `--enable-canonical-system-headers' ! `--disable-canonical-system-headers' ! Enable system header path canonicalization for `libcpp'. This can produce shorter header file paths in diagnostics and dependency ! output files, but these changed header paths may conflict with ! some compilation environments. Enabled by default, and may be ! disabled using `--disable-canonical-system-headers'. Cross-Compiler-Specific Options ------------------------------- The following options only apply to building cross compilers. ! `--with-sysroot' ! `--with-sysroot=DIR' Tells GCC to consider DIR as the root of a tree that contains (a subset of) the root filesystem of the target operating system. Target system headers, libraries and run-time object files will be searched for in there. More specifically, this acts as if ! `--sysroot=DIR' was added to the default options of the built compiler. The specified directory is not copied into the install ! tree, unlike the options `--with-headers' and `--with-libs' that ! this option obsoletes. The default value, in case ! `--with-sysroot' is not given an argument, is ! `${gcc_tooldir}/sys-root'. If the specified directory is a ! subdirectory of `${exec_prefix}', then it will be found relative to ! the GCC binaries if the installation tree is moved. This option affects the system root for the compiler used to build target libraries (which runs on the build system) and the compiler ! newly installed with `make install'; it does not affect the compiler which is used to build GCC itself. ! If you specify the `--with-native-system-header-dir=DIRNAME' ! option then the compiler will search that directory within DIRNAME ! for native system headers rather than the default `/usr/include'. ! `--with-build-sysroot' ! `--with-build-sysroot=DIR' ! Tells GCC to consider DIR as the system root (see ! `--with-sysroot') while building target libraries, instead of the ! directory specified with `--with-sysroot'. This option is only ! useful when you are already using `--with-sysroot'. You can use ! `--with-build-sysroot' when you are configuring with `--prefix' ! set to a directory that is different from the one in which you are ! installing GCC and your target libraries. This option affects the system root for the compiler used to build target libraries (which runs on the build system); it does not affect the compiler which is used to build GCC itself. ! If you specify the `--with-native-system-header-dir=DIRNAME' ! option then the compiler will search that directory within DIRNAME ! for native system headers rather than the default `/usr/include'. ! `--with-headers' ! `--with-headers=DIR' ! Deprecated in favor of `--with-sysroot'. Specifies that target headers are available when building a cross compiler. The DIR argument specifies a directory which has the target include files. ! These include files will be copied into the `gcc' install directory. _This option with the DIR argument is required_ when ! building a cross compiler, if `PREFIX/TARGET/sys-include' doesn't ! pre-exist. If `PREFIX/TARGET/sys-include' does pre-exist, the DIR ! argument may be omitted. `fixincludes' will be run on these files to make them compatible with GCC. ! `--without-headers' Tells GCC not use any target headers from a libc when building a cross compiler. When crossing to GNU/Linux, you need the headers so GCC can build the exception handling for libgcc. ! `--with-libs' ! `--with-libs="DIR1 DIR2 ... DIRN"' ! Deprecated in favor of `--with-sysroot'. Specifies a list of directories which contain the target runtime libraries. These ! libraries will be copied into the `gcc' install directory. If the directory list is omitted, this option has no effect. ! `--with-newlib' ! Specifies that `newlib' is being used as the target C library. ! This causes `__eprintf' to be omitted from `libgcc.a' on the ! assumption that it will be provided by `newlib'. ! `--with-avrlibc' ! Specifies that `AVR-Libc' is being used as the target C library. ! This causes float support functions like `__addsf3' to be omitted ! from `libgcc.a' on the assumption that it will be provided by ! `libm.a'. For more technical details, cf. PR54461. This option is only supported for the AVR target. It is not supported for RTEMS configurations, which currently use newlib. The option is supported since version 4.7.2 and is the default in 4.8.0 and newer. ! `--with-build-time-tools=DIR' ! Specifies where to find the set of target tools (assembler, ! linker, etc.) that will be used while building GCC itself. This ! option can be useful if the directory layouts are different ! between the system you are building GCC on, and the system where ! you will deploy it. ! For example, on an `ia64-hp-hpux' system, you may have the GNU ! assembler and linker in `/usr/bin', and the native tools in a different path, and build a toolchain that expects to find the ! native tools in `/usr/bin'. ! When you use this option, you should ensure that DIR includes ! `ar', `as', `ld', `nm', `ranlib' and `strip' if necessary, and ! possibly `objdump'. Otherwise, GCC may use an inconsistent set of ! tools. Java-Specific Options --------------------- The following option applies to the build of the Java front end. ! `--disable-libgcj' Specify that the run-time libraries used by GCJ should not be built. This is useful in case you intend to use GCJ with some other run-time, or you're going to install it separately, or it just happens not to build on your particular machine. In general, ! if the Java front end is enabled, the GCJ libraries will be ! enabled too, unless they're known to not work on the target ! platform. If GCJ is enabled but `libgcj' isn't built, you may ! need to port it; in this case, before modifying the top-level ! `configure.in' so that `libgcj' is enabled by default on this ! platform, you may use `--enable-libgcj' to override the default. ! ! The following options apply to building `libgcj'. General Options ............... ! `--enable-java-maintainer-mode' ! By default the `libjava' build will not attempt to compile the ! `.java' source files to `.class'. Instead, it will use the ! `.class' files from the source tree. If you use this option you ! must have executables named `ecj1' and `gjavah' in your path for ! use by the build. You must use this option if you intend to ! modify any `.java' files in `libjava'. ! `--with-java-home=DIRNAME' ! This `libjava' option overrides the default value of the ! `java.home' system property. It is also used to set ! `sun.boot.class.path' to `DIRNAME/lib/rt.jar'. By default ! `java.home' is set to `PREFIX' and `sun.boot.class.path' to ! `DATADIR/java/libgcj-VERSION.jar'. ! `--with-ecj-jar=FILENAME' This option can be used to specify the location of an external jar file containing the Eclipse Java compiler. A specially modified ! version of this compiler is used by `gcj' to parse `.java' source ! files. If this option is given, the `libjava' build will create ! and install an `ecj1' executable which uses this jar file at runtime. ! If this option is not given, but an `ecj.jar' file is found in the ! topmost source tree at configure time, then the `libgcj' build ! will create and install `ecj1', and will also install the ! discovered `ecj.jar' into a suitable place in the install tree. ! If `ecj1' is not installed, then the user will have to supply one ! on his path in order for `gcj' to properly parse `.java' source files. A suitable jar is available from ! `ftp://sourceware.org/pub/java/'. ! `--disable-getenv-properties' ! Don't set system properties from `GCJ_PROPERTIES'. ! `--enable-hash-synchronization' ! Use a global hash table for monitor locks. Ordinarily, `libgcj''s ! `configure' script automatically makes the correct choice for this option for your platform. Only use this if you know you need the library to be configured differently. ! `--enable-interpreter' Enable the Java interpreter. The interpreter is automatically enabled by default on all platforms that support it. This option ! is really only useful if you want to disable the interpreter ! (using `--disable-interpreter'). ! `--disable-java-net' Disable java.net. This disables the native part of java.net only, using non-functional stubs for native method implementations. ! `--disable-jvmpi' Disable JVMPI support. ! `--disable-libgcj-bc' Disable BC ABI compilation of certain parts of libgcj. By default, ! some portions of libgcj are compiled with `-findirect-dispatch' ! and `-fno-indirect-classes', allowing them to be overridden at run-time. ! If `--disable-libgcj-bc' is specified, libgcj is built without these options. This allows the compile-time linker to resolve dependencies when statically linking to libgcj. However it makes it impossible to override the affected portions of libgcj at run-time. ! `--enable-reduced-reflection' ! Build most of libgcj with `-freduced-reflection'. This reduces ! the size of libgcj at the expense of not being able to do accurate reflection on the classes it contains. This option is safe if you know that code using libgcj will never use reflection on the standard runtime classes in libgcj (including using serialization, RMI or CORBA). ! `--with-ecos' Enable runtime eCos target support. ! `--without-libffi' ! Don't use `libffi'. This will disable the interpreter and JNI ! support as well, as these require `libffi' to work. ! `--enable-libgcj-debug' Enable runtime debugging code. ! `--enable-libgcj-multifile' ! If specified, causes all `.java' source files to be compiled into ! `.class' files in one invocation of `gcj'. This can speed up ! build time, but is more resource-intensive. If this option is ! unspecified or disabled, `gcj' is invoked once for each `.java' ! file to compile into a `.class' file. ! `--with-libiconv-prefix=DIR' ! Search for libiconv in `DIR/include' and `DIR/lib'. ! `--enable-sjlj-exceptions' ! Force use of the `setjmp'/`longjmp'-based scheme for exceptions. ! `configure' ordinarily picks the correct value based on the platform. Only use this option if you are sure you need a different setting. ! `--with-system-zlib' ! Use installed `zlib' rather than that included with GCC. ! `--with-win32-nlsapi=ansi, unicows or unicode' ! Indicates how MinGW `libgcj' translates between UNICODE characters and the Win32 API. ! `--enable-java-home' If enabled, this creates a JPackage compatible SDK environment during install. Note that if -enable-java-home is used, -with-arch-directory=ARCH must also be specified. ! `--with-arch-directory=ARCH' ! Specifies the name to use for the `jre/lib/ARCH' directory in the ! SDK environment created when -enable-java-home is passed. Typical names for this directory include i386, amd64, ia64, etc. ! `--with-os-directory=DIR' ! Specifies the OS directory for the SDK include directory. This is set to auto detect, and is typically 'linux'. ! `--with-origin-name=NAME' ! Specifies the JPackage origin name. This defaults to the 'gcj' in java-1.5.0-gcj. ! `--with-arch-suffix=SUFFIX' ! Specifies the suffix for the sdk directory. Defaults to the empty string. Examples include '.x86_64' in 'java-1.5.0-gcj-1.5.0.0.x86_64'. ! `--with-jvm-root-dir=DIR' Specifies where to install the SDK. Default is $(prefix)/lib/jvm. ! `--with-jvm-jar-dir=DIR' ! Specifies where to install jars. Default is $(prefix)/lib/jvm-exports. ! `--with-python-dir=DIR' ! Specifies where to install the Python modules used for ! aot-compile. DIR should not include the prefix used in ! installation. For example, if the Python modules are to be ! installed in /usr/lib/python2.5/site-packages, then ! -with-python-dir=/lib/python2.5/site-packages should be passed. If this is not specified, then the Python modules are installed in $(prefix)/share/python. ! `--enable-aot-compile-rpm' Adds aot-compile-rpm to the list of installed scripts. ! `--enable-browser-plugin' Build the gcjwebplugin web browser plugin. ! `--enable-static-libjava' ! Build static libraries in libjava. The default is to only build shared libraries. ! `ansi' ! Use the single-byte `char' and the Win32 A functions natively, translating to and from UNICODE when using these functions. If unspecified, this is the default. ! `unicows' ! Use the `WCHAR' and Win32 W functions natively. Adds ! `-lunicows' to `libgcj.spec' to link with `libunicows'. ! `unicows.dll' needs to be deployed on Microsoft Windows 9X ! machines running built executables. `libunicows.a', an ! open-source import library around Microsoft's `unicows.dll', ! is obtained from `http://libunicows.sourceforge.net/', which ! also gives details on getting `unicows.dll' from Microsoft. ! `unicode' ! Use the `WCHAR' and Win32 W functions natively. Does _not_ ! add `-lunicows' to `libgcj.spec'. The built executables will only run on Microsoft Windows NT and above. AWT-Specific Options .................... ! `--with-x' Use the X Window System. ! `--enable-java-awt=PEER(S)' Specifies the AWT peer library or libraries to build alongside ! `libgcj'. If this option is unspecified or disabled, AWT will be ! non-functional. Current valid values are `gtk' and `xlib'. Multiple libraries should be separated by a comma (i.e. ! `--enable-java-awt=gtk,xlib'). ! `--enable-gtk-cairo' Build the cairo Graphics2D implementation on GTK. ! `--enable-java-gc=TYPE' ! Choose garbage collector. Defaults to `boehm' if unspecified. ! `--disable-gtktest' Do not try to compile and run a test GTK+ program. ! `--disable-glibtest' Do not try to compile and run a test GLIB program. ! `--with-libart-prefix=PFX' Prefix where libart is installed (optional). ! `--with-libart-exec-prefix=PFX' Exec prefix where libart is installed (optional). ! `--disable-libarttest' Do not try to compile and run a test libart program. ! ! Overriding `configure' test results ................................... Sometimes, it might be necessary to override the result of some ! `configure' test, for example in order to ease porting to a new system ! or work around a bug in a test. The toplevel `configure' script provides three variables for this: ! `build_configargs' ! The contents of this variable is passed to all build `configure' scripts. ! `host_configargs' ! The contents of this variable is passed to all host `configure' scripts. ! `target_configargs' ! The contents of this variable is passed to all target `configure' scripts. ! ! In order to avoid shell and `make' quoting issues for complex ! overrides, you can pass a setting for `CONFIG_SITE' and set variables ! in the site file.  File: gccinstall.info, Node: Building, Next: Testing, Prev: Configuration, Up: Installing GCC --- 1195,1851 ---- affects sparc-linux, powerpc-linux, x86-linux, mips-linux and s390-linux. ! '--enable-secureplt' ! This option enables '-msecure-plt' by default for powerpc-linux. *Note RS/6000 and PowerPC Options: (gcc)RS/6000 and PowerPC Options, ! '--enable-cld' ! This option enables '-mcld' by default for 32-bit x86 targets. *Note i386 and x86-64 Options: (gcc)i386 and x86-64 Options, ! '--enable-win32-registry' ! '--enable-win32-registry=KEY' ! '--disable-win32-registry' ! The '--enable-win32-registry' option enables Microsoft Windows-hosted GCC to look up installations paths in the registry using the following key: ! HKEY_LOCAL_MACHINE\SOFTWARE\Free Software Foundation\KEY KEY defaults to GCC version number, and can be overridden by the ! '--enable-win32-registry=KEY' option. Vendors and distributors who ! use custom installers are encouraged to provide a different key, ! perhaps one comprised of vendor name and GCC version number, to ! avoid conflict with existing installations. This feature is enabled by default, and can be disabled by ! '--disable-win32-registry' option. This option has no effect on the other hosts. ! '--nfp' Specify that the machine does not have a floating point unit. This ! option only applies to 'm68k-sun-sunosN'. On any other system, ! '--nfp' has no effect. ! '--enable-werror' ! '--disable-werror' ! '--enable-werror=yes' ! '--enable-werror=no' When you specify this option, it controls whether certain files in ! the compiler are built with '-Werror' in bootstrap stage2 and ! later. If you don't specify it, '-Werror' is turned on for the main development trunk. However it defaults to off for release branches and final releases. The specific files which get ! '-Werror' are controlled by the Makefiles. ! '--enable-checking' ! '--enable-checking=LIST' When you specify this option, the compiler is built to perform ! internal consistency checks of the requested complexity. This does ! not change the generated code, but adds error checking within the ! compiler. This will slow down the compiler and may only work ! properly if you are building the compiler with GCC. This is 'yes' ! by default when building from SVN or snapshots, but 'release' for ! releases. The default for building the stage1 compiler is 'yes'. More control over the checks may be had by specifying LIST. The ! categories of checks available are 'yes' (most common checks ! 'assert,misc,tree,gc,rtlflag,runtime'), 'no' (no checks at all), ! 'all' (all but 'valgrind'), 'release' (cheapest checks ! 'assert,runtime') or 'none' (same as 'no'). Individual checks can ! be enabled with these flags 'assert', 'df', 'fold', 'gc', 'gcac' ! 'misc', 'rtl', 'rtlflag', 'runtime', 'tree', and 'valgrind'. ! The 'valgrind' check requires the external 'valgrind' simulator, ! available from . The 'df', 'rtl', 'gcac' and ! 'valgrind' checks are very expensive. To disable all checking, ! '--disable-checking' or '--enable-checking=none' must be explicitly ! requested. Disabling assertions will make the compiler and runtime ! slightly faster but increase the risk of undetected internal errors ! causing wrong code to be generated. ! '--disable-stage1-checking' ! '--enable-stage1-checking' ! '--enable-stage1-checking=LIST' ! If no '--enable-checking' option is specified the stage1 compiler ! will be built with 'yes' checking enabled, otherwise the stage1 ! checking flags are the same as specified by '--enable-checking'. To build the stage1 compiler with different checking options use ! '--enable-stage1-checking'. The list of checking options is the ! same as for '--enable-checking'. If your system is too slow or too ! small to bootstrap a released compiler with checking for stage1 ! enabled, you can use '--disable-stage1-checking' to disable checking for the stage1 compiler. ! '--enable-coverage' ! '--enable-coverage=LEVEL' With this option, the compiler is built to collect self coverage information, every time it is run. This is for internal development purposes, and only works when the compiler is being built with gcc. The LEVEL argument controls whether the compiler ! is built optimized or not, values are 'opt' and 'noopt'. For ! coverage analysis you want to disable optimization, for performance ! analysis you want to enable optimization. When coverage is ! enabled, the default level is without optimization. ! '--enable-gather-detailed-mem-stats' When this option is specified more detailed information on memory allocation is gathered. This information is printed when using ! '-fmem-report'. ! '--enable-nls' ! '--disable-nls' ! The '--enable-nls' option enables Native Language Support (NLS), which lets GCC output diagnostics in languages other than American English. Native Language Support is enabled by default if not ! doing a canadian cross build. The '--disable-nls' option disables NLS. ! '--with-included-gettext' ! If NLS is enabled, the '--with-included-gettext' option causes the ! build procedure to prefer its copy of GNU 'gettext'. ! '--with-catgets' ! If NLS is enabled, and if the host lacks 'gettext' but has the ! inferior 'catgets' interface, the GCC build procedure normally ! ignores 'catgets' and instead uses GCC's copy of the GNU 'gettext' ! library. The '--with-catgets' option causes the build procedure to ! use the host's 'catgets' in this situation. ! '--with-libiconv-prefix=DIR' ! Search for libiconv header files in 'DIR/include' and libiconv ! library files in 'DIR/lib'. ! '--enable-obsolete' Enable configuration for an obsoleted system. If you attempt to configure GCC for a system (build, host, or target) which has been obsoleted, and you do not specify this flag, configure will halt with an error message. ! All support for systems which have been obsoleted in one release of ! GCC is removed entirely in the next major release, unless someone ! steps forward to maintain the port. ! '--enable-decimal-float' ! '--enable-decimal-float=yes' ! '--enable-decimal-float=no' ! '--enable-decimal-float=bid' ! '--enable-decimal-float=dpd' ! '--disable-decimal-float' Enable (or disable) support for the C decimal floating point extension that is in the IEEE 754-2008 standard. This is enabled by default only on PowerPC, i386, and x86_64 GNU/Linux systems. Other systems may also support it, but require the user to specifically enable it. You can optionally control which decimal ! floating point format is used (either 'bid' or 'dpd'). The 'bid' (binary integer decimal) format is default on i386 and x86_64 ! systems, and the 'dpd' (densely packed decimal) format is default on PowerPC systems. ! '--enable-fixed-point' ! '--disable-fixed-point' Enable (or disable) support for C fixed-point arithmetic. This option is enabled by default for some targets (such as MIPS) which have hardware-support for fixed-point operations. On other targets, you may enable this option manually. ! '--with-long-double-128' ! Specify if 'long double' type should be 128-bit by default on selected GNU/Linux architectures. If using ! '--without-long-double-128', 'long double' will be by default ! 64-bit, the same as 'double' type. When neither of these configure ! options are used, the default will be 128-bit 'long double' when ! built against GNU C Library 2.4 and later, 64-bit 'long double' ! otherwise. ! '--with-gmp=PATHNAME' ! '--with-gmp-include=PATHNAME' ! '--with-gmp-lib=PATHNAME' ! '--with-mpfr=PATHNAME' ! '--with-mpfr-include=PATHNAME' ! '--with-mpfr-lib=PATHNAME' ! '--with-mpc=PATHNAME' ! '--with-mpc-include=PATHNAME' ! '--with-mpc-lib=PATHNAME' If you want to build GCC but do not have the GMP library, the MPFR library and/or the MPC library installed in a standard location and do not have their sources present in the GCC source tree then you can explicitly specify the directory where they are installed ! ('--with-gmp=GMPINSTALLDIR', '--with-mpfr=MPFRINSTALLDIR', ! '--with-mpc=MPCINSTALLDIR'). The '--with-gmp=GMPINSTALLDIR' option ! is shorthand for '--with-gmp-lib=GMPINSTALLDIR/lib' and ! '--with-gmp-include=GMPINSTALLDIR/include'. Likewise the ! '--with-mpfr=MPFRINSTALLDIR' option is shorthand for ! '--with-mpfr-lib=MPFRINSTALLDIR/lib' and ! '--with-mpfr-include=MPFRINSTALLDIR/include', also the ! '--with-mpc=MPCINSTALLDIR' option is shorthand for ! '--with-mpc-lib=MPCINSTALLDIR/lib' and ! '--with-mpc-include=MPCINSTALLDIR/include'. If these shorthand assumptions are not correct, you can use the explicit include and lib options directly. You might also need to ensure the shared libraries can be found by the dynamic linker when building and using GCC, for example by setting the runtime shared library path ! variable ('LD_LIBRARY_PATH' on GNU/Linux and Solaris systems). These flags are applicable to the host platform only. When building a cross compiler, they will not be used to configure target libraries. ! '--with-isl=PATHNAME' ! '--with-isl-include=PATHNAME' ! '--with-isl-lib=PATHNAME' ! '--with-cloog=PATHNAME' ! '--with-cloog-include=PATHNAME' ! '--with-cloog-lib=PATHNAME' If you do not have ISL and the CLooG libraries installed in a standard location and you want to build GCC, you can explicitly specify the directory where they are installed ! ('--with-isl=ISLINSTALLDIR', '--with-cloog=CLOOGINSTALLDIR'). The ! '--with-isl=ISLINSTALLDIR' option is shorthand for ! '--with-isl-lib=ISLINSTALLDIR/lib' and ! '--with-isl-include=ISLINSTALLDIR/include'. Likewise the ! '--with-cloog=CLOOGINSTALLDIR' option is shorthand for ! '--with-cloog-lib=CLOOGINSTALLDIR/lib' and ! '--with-cloog-include=CLOOGINSTALLDIR/include'. If these shorthand ! assumptions are not correct, you can use the explicit include and ! lib options directly. These flags are applicable to the host platform only. When building a cross compiler, they will not be used to configure target libraries. ! '--with-host-libstdcxx=LINKER-ARGS' If you are linking with a static copy of PPL, you can use this option to specify how the linker should find the standard C++ ! library used internally by PPL. Typical values of LINKER-ARGS might ! be '-lstdc++' or '-Wl,-Bstatic,-lstdc++,-Bdynamic -lm'. If you are ! linking with a shared copy of PPL, you probably do not need this ! option; shared library dependencies will cause the linker to search ! for the standard C++ library automatically. ! '--with-stage1-ldflags=FLAGS' This option may be used to set linker flags to be used when linking ! stage 1 of GCC. These are also used when linking GCC if configured ! with '--disable-bootstrap'. By default no special flags are used. ! '--with-stage1-libs=LIBS' This option may be used to set libraries to be used when linking ! stage 1 of GCC. These are also used when linking GCC if configured ! with '--disable-bootstrap'. The default is the argument to ! '--with-host-libstdcxx', if specified. ! '--with-boot-ldflags=FLAGS' This option may be used to set linker flags to be used when linking ! stage 2 and later when bootstrapping GCC. If neither -with-boot-libs nor -with-host-libstdcxx is set to a value, then ! the default is '-static-libstdc++ -static-libgcc'. ! '--with-boot-libs=LIBS' This option may be used to set libraries to be used when linking ! stage 2 and later when bootstrapping GCC. The default is the ! argument to '--with-host-libstdcxx', if specified. ! '--with-debug-prefix-map=MAP' ! Convert source directory names using '-fdebug-prefix-map' when ! building runtime libraries. 'MAP' is a space-separated list of ! maps of the form 'OLD=NEW'. ! '--enable-linker-build-id' ! Tells GCC to pass '--build-id' option to the linker for all final ! links (links performed without the '-r' or '--relocatable' option), ! if the linker supports it. If you specify ! '--enable-linker-build-id', but your linker does not support ! '--build-id' option, a warning is issued and the ! '--enable-linker-build-id' option is ignored. The default is off. ! '--with-linker-hash-style=CHOICE' ! Tells GCC to pass '--hash-style=CHOICE' option to the linker for ! all final links. CHOICE can be one of 'sysv', 'gnu', and 'both' ! where 'sysv' is the default. ! '--enable-gnu-unique-object' ! '--disable-gnu-unique-object' Tells GCC to use the gnu_unique_object relocation for C++ template static data members and inline function local statics. Enabled by default for a native toolchain with an assembler that accepts it and GLIBC 2.11 or above, otherwise disabled. ! '--enable-lto' ! '--disable-lto' ! Enable support for link-time optimization (LTO). This is enabled by ! default, and may be disabled using '--disable-lto'. ! '--with-plugin-ld=PATHNAME' Enable an alternate linker to be used at link-time optimization ! (LTO) link time when '-fuse-linker-plugin' is enabled. This linker ! should have plugin support such as gold starting with version 2.20 ! or GNU ld starting with version 2.21. See '-fuse-linker-plugin' ! for details. ! '--enable-canonical-system-headers' ! '--disable-canonical-system-headers' ! Enable system header path canonicalization for 'libcpp'. This can produce shorter header file paths in diagnostics and dependency ! output files, but these changed header paths may conflict with some ! compilation environments. Enabled by default, and may be disabled ! using '--disable-canonical-system-headers'. Cross-Compiler-Specific Options ------------------------------- The following options only apply to building cross compilers. ! '--with-sysroot' ! '--with-sysroot=DIR' Tells GCC to consider DIR as the root of a tree that contains (a subset of) the root filesystem of the target operating system. Target system headers, libraries and run-time object files will be searched for in there. More specifically, this acts as if ! '--sysroot=DIR' was added to the default options of the built compiler. The specified directory is not copied into the install ! tree, unlike the options '--with-headers' and '--with-libs' that ! this option obsoletes. The default value, in case '--with-sysroot' ! is not given an argument, is '${gcc_tooldir}/sys-root'. If the ! specified directory is a subdirectory of '${exec_prefix}', then it ! will be found relative to the GCC binaries if the installation tree ! is moved. This option affects the system root for the compiler used to build target libraries (which runs on the build system) and the compiler ! newly installed with 'make install'; it does not affect the compiler which is used to build GCC itself. ! If you specify the '--with-native-system-header-dir=DIRNAME' option ! then the compiler will search that directory within DIRNAME for ! native system headers rather than the default '/usr/include'. ! '--with-build-sysroot' ! '--with-build-sysroot=DIR' ! Tells GCC to consider DIR as the system root (see '--with-sysroot') ! while building target libraries, instead of the directory specified ! with '--with-sysroot'. This option is only useful when you are ! already using '--with-sysroot'. You can use '--with-build-sysroot' ! when you are configuring with '--prefix' set to a directory that is ! different from the one in which you are installing GCC and your ! target libraries. This option affects the system root for the compiler used to build target libraries (which runs on the build system); it does not affect the compiler which is used to build GCC itself. ! If you specify the '--with-native-system-header-dir=DIRNAME' option ! then the compiler will search that directory within DIRNAME for ! native system headers rather than the default '/usr/include'. ! '--with-headers' ! '--with-headers=DIR' ! Deprecated in favor of '--with-sysroot'. Specifies that target headers are available when building a cross compiler. The DIR argument specifies a directory which has the target include files. ! These include files will be copied into the 'gcc' install directory. _This option with the DIR argument is required_ when ! building a cross compiler, if 'PREFIX/TARGET/sys-include' doesn't ! pre-exist. If 'PREFIX/TARGET/sys-include' does pre-exist, the DIR ! argument may be omitted. 'fixincludes' will be run on these files to make them compatible with GCC. ! '--without-headers' Tells GCC not use any target headers from a libc when building a cross compiler. When crossing to GNU/Linux, you need the headers so GCC can build the exception handling for libgcc. ! '--with-libs' ! '--with-libs="DIR1 DIR2 ... DIRN"' ! Deprecated in favor of '--with-sysroot'. Specifies a list of directories which contain the target runtime libraries. These ! libraries will be copied into the 'gcc' install directory. If the directory list is omitted, this option has no effect. ! '--with-newlib' ! Specifies that 'newlib' is being used as the target C library. ! This causes '__eprintf' to be omitted from 'libgcc.a' on the ! assumption that it will be provided by 'newlib'. ! '--with-avrlibc' ! Specifies that 'AVR-Libc' is being used as the target C library. ! This causes float support functions like '__addsf3' to be omitted ! from 'libgcc.a' on the assumption that it will be provided by ! 'libm.a'. For more technical details, cf. PR54461. This option is only supported for the AVR target. It is not supported for RTEMS configurations, which currently use newlib. The option is supported since version 4.7.2 and is the default in 4.8.0 and newer. ! '--with-build-time-tools=DIR' ! Specifies where to find the set of target tools (assembler, linker, ! etc.) that will be used while building GCC itself. This option ! can be useful if the directory layouts are different between the ! system you are building GCC on, and the system where you will ! deploy it. ! For example, on an 'ia64-hp-hpux' system, you may have the GNU ! assembler and linker in '/usr/bin', and the native tools in a different path, and build a toolchain that expects to find the ! native tools in '/usr/bin'. ! When you use this option, you should ensure that DIR includes 'ar', ! 'as', 'ld', 'nm', 'ranlib' and 'strip' if necessary, and possibly ! 'objdump'. Otherwise, GCC may use an inconsistent set of tools. Java-Specific Options --------------------- The following option applies to the build of the Java front end. ! '--disable-libgcj' Specify that the run-time libraries used by GCJ should not be built. This is useful in case you intend to use GCJ with some other run-time, or you're going to install it separately, or it just happens not to build on your particular machine. In general, ! if the Java front end is enabled, the GCJ libraries will be enabled ! too, unless they're known to not work on the target platform. If ! GCJ is enabled but 'libgcj' isn't built, you may need to port it; ! in this case, before modifying the top-level 'configure.in' so that ! 'libgcj' is enabled by default on this platform, you may use ! '--enable-libgcj' to override the default. ! The following options apply to building 'libgcj'. General Options ............... ! '--enable-java-maintainer-mode' ! By default the 'libjava' build will not attempt to compile the ! '.java' source files to '.class'. Instead, it will use the ! '.class' files from the source tree. If you use this option you ! must have executables named 'ecj1' and 'gjavah' in your path for ! use by the build. You must use this option if you intend to modify ! any '.java' files in 'libjava'. ! '--with-java-home=DIRNAME' ! This 'libjava' option overrides the default value of the ! 'java.home' system property. It is also used to set ! 'sun.boot.class.path' to 'DIRNAME/lib/rt.jar'. By default ! 'java.home' is set to 'PREFIX' and 'sun.boot.class.path' to ! 'DATADIR/java/libgcj-VERSION.jar'. ! '--with-ecj-jar=FILENAME' This option can be used to specify the location of an external jar file containing the Eclipse Java compiler. A specially modified ! version of this compiler is used by 'gcj' to parse '.java' source ! files. If this option is given, the 'libjava' build will create ! and install an 'ecj1' executable which uses this jar file at runtime. ! If this option is not given, but an 'ecj.jar' file is found in the ! topmost source tree at configure time, then the 'libgcj' build will ! create and install 'ecj1', and will also install the discovered ! 'ecj.jar' into a suitable place in the install tree. ! If 'ecj1' is not installed, then the user will have to supply one ! on his path in order for 'gcj' to properly parse '.java' source files. A suitable jar is available from ! . ! '--disable-getenv-properties' ! Don't set system properties from 'GCJ_PROPERTIES'. ! '--enable-hash-synchronization' ! Use a global hash table for monitor locks. Ordinarily, 'libgcj''s ! 'configure' script automatically makes the correct choice for this option for your platform. Only use this if you know you need the library to be configured differently. ! '--enable-interpreter' Enable the Java interpreter. The interpreter is automatically enabled by default on all platforms that support it. This option ! is really only useful if you want to disable the interpreter (using ! '--disable-interpreter'). ! '--disable-java-net' Disable java.net. This disables the native part of java.net only, using non-functional stubs for native method implementations. ! '--disable-jvmpi' Disable JVMPI support. ! '--disable-libgcj-bc' Disable BC ABI compilation of certain parts of libgcj. By default, ! some portions of libgcj are compiled with '-findirect-dispatch' and ! '-fno-indirect-classes', allowing them to be overridden at run-time. ! If '--disable-libgcj-bc' is specified, libgcj is built without these options. This allows the compile-time linker to resolve dependencies when statically linking to libgcj. However it makes it impossible to override the affected portions of libgcj at run-time. ! '--enable-reduced-reflection' ! Build most of libgcj with '-freduced-reflection'. This reduces the ! size of libgcj at the expense of not being able to do accurate reflection on the classes it contains. This option is safe if you know that code using libgcj will never use reflection on the standard runtime classes in libgcj (including using serialization, RMI or CORBA). ! '--with-ecos' Enable runtime eCos target support. ! '--without-libffi' ! Don't use 'libffi'. This will disable the interpreter and JNI ! support as well, as these require 'libffi' to work. ! '--enable-libgcj-debug' Enable runtime debugging code. ! '--enable-libgcj-multifile' ! If specified, causes all '.java' source files to be compiled into ! '.class' files in one invocation of 'gcj'. This can speed up build ! time, but is more resource-intensive. If this option is ! unspecified or disabled, 'gcj' is invoked once for each '.java' ! file to compile into a '.class' file. ! '--with-libiconv-prefix=DIR' ! Search for libiconv in 'DIR/include' and 'DIR/lib'. ! '--enable-sjlj-exceptions' ! Force use of the 'setjmp'/'longjmp'-based scheme for exceptions. ! 'configure' ordinarily picks the correct value based on the platform. Only use this option if you are sure you need a different setting. ! '--with-system-zlib' ! Use installed 'zlib' rather than that included with GCC. ! '--with-win32-nlsapi=ansi, unicows or unicode' ! Indicates how MinGW 'libgcj' translates between UNICODE characters and the Win32 API. ! '--enable-java-home' If enabled, this creates a JPackage compatible SDK environment during install. Note that if -enable-java-home is used, -with-arch-directory=ARCH must also be specified. ! '--with-arch-directory=ARCH' ! Specifies the name to use for the 'jre/lib/ARCH' directory in the ! SDK environment created when -enable-java-home is passed. Typical names for this directory include i386, amd64, ia64, etc. ! '--with-os-directory=DIR' ! Specifies the OS directory for the SDK include directory. This is set to auto detect, and is typically 'linux'. ! '--with-origin-name=NAME' ! Specifies the JPackage origin name. This defaults to the 'gcj' in java-1.5.0-gcj. ! '--with-arch-suffix=SUFFIX' ! Specifies the suffix for the sdk directory. Defaults to the empty string. Examples include '.x86_64' in 'java-1.5.0-gcj-1.5.0.0.x86_64'. ! '--with-jvm-root-dir=DIR' Specifies where to install the SDK. Default is $(prefix)/lib/jvm. ! '--with-jvm-jar-dir=DIR' ! Specifies where to install jars. Default is $(prefix)/lib/jvm-exports. ! '--with-python-dir=DIR' ! Specifies where to install the Python modules used for aot-compile. ! DIR should not include the prefix used in installation. For ! example, if the Python modules are to be installed in ! /usr/lib/python2.5/site-packages, then ! -with-python-dir=/lib/python2.5/site-packages should be passed. If this is not specified, then the Python modules are installed in $(prefix)/share/python. ! '--enable-aot-compile-rpm' Adds aot-compile-rpm to the list of installed scripts. ! '--enable-browser-plugin' Build the gcjwebplugin web browser plugin. ! '--enable-static-libjava' ! Build static libraries in libjava. The default is to only build shared libraries. ! 'ansi' ! Use the single-byte 'char' and the Win32 A functions natively, translating to and from UNICODE when using these functions. If unspecified, this is the default. ! 'unicows' ! Use the 'WCHAR' and Win32 W functions natively. Adds ! '-lunicows' to 'libgcj.spec' to link with 'libunicows'. ! 'unicows.dll' needs to be deployed on Microsoft Windows 9X ! machines running built executables. 'libunicows.a', an ! open-source import library around Microsoft's 'unicows.dll', ! is obtained from , which ! also gives details on getting 'unicows.dll' from Microsoft. ! 'unicode' ! Use the 'WCHAR' and Win32 W functions natively. Does _not_ ! add '-lunicows' to 'libgcj.spec'. The built executables will only run on Microsoft Windows NT and above. AWT-Specific Options .................... ! '--with-x' Use the X Window System. ! '--enable-java-awt=PEER(S)' Specifies the AWT peer library or libraries to build alongside ! 'libgcj'. If this option is unspecified or disabled, AWT will be ! non-functional. Current valid values are 'gtk' and 'xlib'. Multiple libraries should be separated by a comma (i.e. ! '--enable-java-awt=gtk,xlib'). ! '--enable-gtk-cairo' Build the cairo Graphics2D implementation on GTK. ! '--enable-java-gc=TYPE' ! Choose garbage collector. Defaults to 'boehm' if unspecified. ! '--disable-gtktest' Do not try to compile and run a test GTK+ program. ! '--disable-glibtest' Do not try to compile and run a test GLIB program. ! '--with-libart-prefix=PFX' Prefix where libart is installed (optional). ! '--with-libart-exec-prefix=PFX' Exec prefix where libart is installed (optional). ! '--disable-libarttest' Do not try to compile and run a test libart program. ! Overriding 'configure' test results ................................... Sometimes, it might be necessary to override the result of some ! 'configure' test, for example in order to ease porting to a new system ! or work around a bug in a test. The toplevel 'configure' script provides three variables for this: ! 'build_configargs' ! The contents of this variable is passed to all build 'configure' scripts. ! 'host_configargs' ! The contents of this variable is passed to all host 'configure' scripts. ! 'target_configargs' ! The contents of this variable is passed to all target 'configure' scripts. ! In order to avoid shell and 'make' quoting issues for complex ! overrides, you can pass a setting for 'CONFIG_SITE' and set variables in ! the site file.

At present GCC supports _only_ the very ! recent VxWorks 5.5 (aka Tornado 2.2) release, and only on PowerPC. We ! welcome patches for other architectures supported by VxWorks 5.5. Support for VxWorks AE would also be welcome; we believe this is merely a matter of writing an appropriate "configlette" (see below). We are not interested in supporting older, a.out or COFF-based, versions of VxWorks in GCC 3. VxWorks comes with an older version of GCC installed in ! '$WIND_BASE/host'; we recommend you do not overwrite it. Choose an installation PREFIX entirely outside $WIND_BASE. Before running ! 'configure', create the directories 'PREFIX' and 'PREFIX/bin'. Link or ! copy the appropriate assembler, linker, etc. into 'PREFIX/bin', and set ! your PATH to include that directory while running both 'configure' and ! 'make'. ! You must give 'configure' the '--with-headers=$WIND_BASE/target/h' ! switch so that it can find the VxWorks system headers. Since VxWorks is ! a cross compilation target only, you must also specify !

On GNU/Linux the default is a bi-arch compiler which is able to generate ! both 64-bit x86-64 and 32-bit x86 code (via the `-m32' switch). x86_64-*-solaris2.1[0-9]* ========================= GCC also supports the x86-64 architecture implemented by the AMD64 ! processor (`amd64-*-*' is an alias for `x86_64-*-*') on Solaris 10 or ! later.

This target is intended for embedded Xtensa systems using the `newlib' ! C library. It uses ELF but does not support shared objects. Designed-defined instructions specified via the Tensilica Instruction Extension (TIE) language are only supported through inline assembly.

When GCC is configured for a native configuration, the default action ! for `make' is to do a full three-stage bootstrap. This means that GCC is built three times--once with the native compiler, once with the ! native-built compiler it just built, and once with the compiler it ! built the second time. In theory, the last two should produce the same ! results, which `make compare' can check. Each stage is configured separately and compiled into a separate directory, to minimize problems due to ABI incompatibilities between the native compiler and GCC. ! If you do a change, rebuilding will also start from the first stage ! and "bubble" up the change through the three stages. Each stage is ! taken from its build directory (if it had been built previously), ! rebuilt, and copied to its subdirectory. This will allow you to, for ! example, continue a bootstrap after fixing a bug which causes the ! stage2 build to crash. It does not provide as good coverage of the ! compiler as bootstrapping from scratch, but it ensures that the new ! code is syntactically correct (e.g., that you did not use GCC extensions ! by mistake), and avoids spurious bootstrap comparison failures(1). Other targets available from the top level include: ! `bootstrap-lean' ! Like `bootstrap', except that the various stages are removed once they're no longer needed. This saves disk space. ! `bootstrap2' ! `bootstrap2-lean' Performs only the first two stages of bootstrap. Unlike a three-stage bootstrap, this does not perform a comparison to test that the compiler is running properly. Note that the disk space required by a "lean" bootstrap is approximately independent of the number of stages. ! `stageN-bubble (N = 1...4, profile, feedback)' Rebuild all the stages up to N, with the appropriate flags, "bubbling" the changes as described above. ! `all-stageN (N = 1...4, profile, feedback)' Assuming that stage N has already been built, rebuild it with the appropriate flags. This is rarely needed. ! `cleanstrap' ! Remove everything (`make clean') and rebuilds (`make bootstrap'). ! `compare' Compares the results of stages 2 and 3.

Currently only the C language testsuites are documented here; FIXME: ! document the others. * Menu: *************** File: gccint.info, Node: Test Idioms, *** 4243,4284 **** 7.1 Idioms Used in Testsuite Code ================================= ! In general, C testcases have a trailing `-N.c', starting with `-1.c', ! in case other testcases with similar names are added later. If the ! test is a test of some well-defined feature, it should have a name ! referring to that feature such as `FEATURE-1.c'. If it does not test a ! well-defined feature but just happens to exercise a bug somewhere in ! the compiler, and a bug report has been filed for this bug in the GCC ! bug database, `prBUG-NUMBER-1.c' is the appropriate form of name. ! Otherwise (for miscellaneous bugs not filed in the GCC bug database), ! and previously more generally, test cases are named after the date on ! which they were added. This allows people to tell at a glance whether ! a test failure is because of a recently found bug that has not yet been ! fixed, or whether it may be a regression, but does not give any other ! information about the bug or where discussion of it may be found. Some ! other language testsuites follow similar conventions. ! In the `gcc.dg' testsuite, it is often necessary to test that an error is indeed a hard error and not just a warning--for example, where it is a constraint violation in the C standard, which must become an error ! with `-pedantic-errors'. The following idiom, where the first line ! shown is line LINE of the file and the line that generates the error, ! is used for this: /* { dg-bogus "warning" "warning in place of error" } */ /* { dg-error "REGEXP" "MESSAGE" { target *-*-* } LINE } */ It may be necessary to check that an expression is an integer constant ! expression and has a certain value. To check that `E' has value `V', ! an idiom similar to the following is used: char x[((E) == (V) ? 1 : -1)]; ! In `gcc.dg' tests, `__typeof__' is sometimes used to make assertions about the types of expressions. See, for example, ! `gcc.dg/c99-condexpr-1.c'.

It is useful to be able to test that optimizations are being made properly. This cannot be done in all cases, but it can be done where --- 4150,4191 ---- 7.1 Idioms Used in Testsuite Code ================================= ! In general, C testcases have a trailing '-N.c', starting with '-1.c', in ! case other testcases with similar names are added later. If the test is ! a test of some well-defined feature, it should have a name referring to ! that feature such as 'FEATURE-1.c'. If it does not test a well-defined ! feature but just happens to exercise a bug somewhere in the compiler, ! and a bug report has been filed for this bug in the GCC bug database, ! 'prBUG-NUMBER-1.c' is the appropriate form of name. Otherwise (for ! miscellaneous bugs not filed in the GCC bug database), and previously ! more generally, test cases are named after the date on which they were ! added. This allows people to tell at a glance whether a test failure is ! because of a recently found bug that has not yet been fixed, or whether ! it may be a regression, but does not give any other information about ! the bug or where discussion of it may be found. Some other language ! testsuites follow similar conventions. ! In the 'gcc.dg' testsuite, it is often necessary to test that an error is indeed a hard error and not just a warning--for example, where it is a constraint violation in the C standard, which must become an error ! with '-pedantic-errors'. The following idiom, where the first line ! shown is line LINE of the file and the line that generates the error, is ! used for this: /* { dg-bogus "warning" "warning in place of error" } */ /* { dg-error "REGEXP" "MESSAGE" { target *-*-* } LINE } */ It may be necessary to check that an expression is an integer constant ! expression and has a certain value. To check that 'E' has value 'V', an ! idiom similar to the following is used: char x[((E) == (V) ? 1 : -1)]; ! In 'gcc.dg' tests, '__typeof__' is sometimes used to make assertions about the types of expressions. See, for example, ! 'gcc.dg/c99-condexpr-1.c'. The more subtle uses depend on the exact rules for the types of conditional expressions in the C standard; see, ! for example, 'gcc.dg/c99-intconst-1.c'.

All options beginning with "f", "W" or "m" are assumed to have a "no-" form unless this property is used. ! `Negative(OTHERNAME)' The option will turn off another option OTHERNAME, which is the option name with the leading "-" removed. This chain action will ! propagate through the `Negative' property of the option to be turned off. As a consequence, if you have a group of mutually-exclusive ! options, their `Negative' properties should form a circular chain. ! For example, if options `-A', `-B' and `-C' are mutually ! exclusive, their respective `Negative' properties should be ! `Negative(B)', `Negative(C)' and `Negative(A)'. ! `Joined' ! `Separate' ! The option takes a mandatory argument. `Joined' indicates that ! the option and argument can be included in the same `argv' entry ! (as with `-mflush-func=NAME', for example). `Separate' indicates ! that the option and argument can be separate `argv' entries (as ! with `-o'). An option is allowed to have both of these properties. ! `JoinedOrMissing' The option takes an optional argument. If the argument is given, ! it will be part of the same `argv' entry as the option itself. ! This property cannot be used alongside `Joined' or `Separate'. ! `MissingArgError(MESSAGE)' ! For an option marked `Joined' or `Separate', the message MESSAGE will be used as an error message if the mandatory argument is ! missing; for options without `MissingArgError', a generic error ! message is used. MESSAGE should contain a single `%qs' format, which will be used to format the name of the option passed. ! `Args(N)' ! For an option marked `Separate', indicate that it takes N arguments. The default is 1. ! `UInteger' The option's argument is a non-negative integer. The option parser will check and convert the argument before passing it to the ! relevant option handler. `UInteger' should also be used on ! options like `-falign-loops' where both `-falign-loops' and ! `-falign-loops'=N are supported to make sure the saved options are given a full integer. ! `ToLower' The option's argument should be converted to lowercase as part of putting it in canonical form, and before comparing with the strings ! indicated by any `Enum' property. ! `NoDriverArg' ! For an option marked `Separate', the option only takes an argument in the compiler proper, not in the driver. This is for compatibility with existing options that are used both directly and ! via `-Wp,'; new options should not have this property. ! `Var(VAR)' ! The state of this option should be stored in variable VAR ! (actually a macro for `global_options.x_VAR'). The way that the ! state is stored depends on the type of option: ! * If the option uses the `Mask' or `InverseMask' properties, ! VAR is the integer variable that contains the mask. * If the option is a normal on/off switch, VAR is an integer variable that is nonzero when the option is enabled. The options parser will set the variable to 1 when the positive form of the option is used and 0 when the "no-" form is used. ! * If the option takes an argument and has the `UInteger' property, VAR is an integer variable that stores the value of the argument. ! * If the option takes an argument and has the `Enum' property, ! VAR is a variable (type given in the `Type' property of the ! `Enum' record whose `Name' property has the same argument as ! the `Enum' property of this option) that stores the value of the argument. ! * If the option has the `Defer' property, VAR is a pointer to a ! `VEC(cl_deferred_option,heap)' that stores the option for ! later processing. (VAR is declared with type `void *' and ! needs to be cast to `VEC(cl_deferred_option,heap)' before use.) * Otherwise, if the option takes an argument, VAR is a pointer to the argument string. The pointer will be null if the argument is optional and wasn't given. ! The option-processing script will usually zero-initialize VAR. ! You can modify this behavior using `Init'. ! `Var(VAR, SET)' The option controls an integer variable VAR and is active when VAR equals SET. The option parser will set VAR to SET when the ! positive form of the option is used and `!SET' when the "no-" form is used. VAR is declared in the same way as for the single-argument form described above. ! `Init(VALUE)' ! The variable specified by the `Var' property should be statically initialized to VALUE. If more than one option using the same ! variable specifies `Init', all must specify the same initializer. ! `Mask(NAME)' ! The option is associated with a bit in the `target_flags' variable (*note Run-time Target::) and is active when that bit is set. You ! may also specify `Var' to select a variable other than ! `target_flags'. The options-processing script will automatically allocate a unique ! bit for the option. If the option is attached to `target_flags', ! the script will set the macro `MASK_NAME' to the appropriate ! bitmask. It will also declare a `TARGET_NAME' macro that has the value 1 when the option is active and 0 otherwise. If you use ! `Var' to attach the option to a different variable, the bitmask ! macro with be called `OPTION_MASK_NAME'. ! `InverseMask(OTHERNAME)' ! `InverseMask(OTHERNAME, THISNAME)' The option is the inverse of another option that has the ! `Mask(OTHERNAME)' property. If THISNAME is given, the ! options-processing script will declare a `TARGET_THISNAME' macro that is 1 when the option is active and 0 otherwise. ! `Enum(NAME)' The option's argument is a string from the set of strings ! associated with the corresponding `Enum' record. The string is checked and converted to the integer specified in the corresponding ! `EnumValue' record before being passed to option handlers. ! `Defer' ! The option should be stored in a vector, specified with `Var', for later processing. ! `Alias(OPT)' ! `Alias(OPT, ARG)' ! `Alias(OPT, POSARG, NEGARG)' ! The option is an alias for `-OPT' (or the negative form of that ! option, depending on `NegativeAlias'). In the first form, any ! argument passed to the alias is considered to be passed to `-OPT', ! and `-OPT' is considered to be negated if the alias is used in negated form. In the second form, the alias may not be negated or have an argument, and POSARG is considered to be passed as an ! argument to `-OPT'. In the third form, the alias may not have an argument, if the alias is used in the positive form then POSARG is ! considered to be passed to `-OPT', and if the alias is used in the ! negative form then NEGARG is considered to be passed to `-OPT'. ! Aliases should not specify `Var' or `Mask' or `UInteger'. Aliases should normally specify the same languages as the target of the alias; the flags on the target will be used to determine any ! diagnostic for use of an option for the wrong language, while ! those on the alias will be used to identify what command-line text ! is the option and what text is any argument to that option. ! When an `Alias' definition is used for an option, driver specs do ! not need to handle it and no `OPT_' enumeration value is defined for it; only the canonical form of the option will be seen in those places. ! `NegativeAlias' ! For an option marked with `Alias(OPT)', the option is considered ! to be an alias for the positive form of `-OPT' if negated and for ! the negative form of `-OPT' if not negated. `NegativeAlias' may ! not be used with the forms of `Alias' taking more than one ! argument. ! `Ignore' This option is ignored apart from printing any warning specified ! using `Warn'. The option will not be seen by specs and no `OPT_' enumeration value is defined for it. ! `SeparateAlias' ! For an option marked with `Joined', `Separate' and `Alias', the option only acts as an alias when passed a separate argument; with ! a joined argument it acts as a normal option, with an `OPT_' ! enumeration value. This is for compatibility with the Java `-d' option and should not be used for new options. ! `Warn(MESSAGE)' If this option is used, output the warning MESSAGE. MESSAGE is a ! format string, either taking a single operand with a `%qs' format which is the option name, or not taking any operands, which is ! passed to the `warning' function. If an alias is marked `Warn', ! the target of the alias must not also be marked `Warn'. ! `Report' ! The state of the option should be printed by `-fverbose-asm'. ! `Warning' ! This is a warning option and should be shown as such in `--help' output. This flag does not currently affect anything other than ! `--help'. ! `Optimization' This is an optimization option. It should be shown as such in ! `--help' output, and any associated variable named using `Var' ! should be saved and restored when the optimization level is ! changed with `optimize' attributes. ! `Undocumented' The option is deliberately missing documentation and should not be ! included in the `--help' output. ! `Condition(COND)' The option should only be accepted if preprocessor condition COND is true. Note that any C declarations associated with the option ! will be present even if COND is false; COND simply controls ! whether the option is accepted and whether it is printed in the ! `--help' output. ! `Save' ! Build the `cl_target_option' structure to hold a copy of the ! option, add the functions `cl_target_option_save' and ! `cl_target_option_restore' to save and restore the options. ! `SetByCombined' The option may also be set by a combined option such as ! `-ffast-math'. This causes the `gcc_options' struct to have a ! field `frontend_set_NAME', where `NAME' is the name of the field ! holding the value of this option (without the leading `x_'). This gives the front end a way to indicate that the value has been set explicitly and should not be changed by the combined option. For ! example, some front ends use this to prevent `-ffast-math' and ! `-fno-fast-math' from changing the value of `-fmath-errno' for ! languages that do not use `errno'. ! `EnabledBy(OPT)' ! `EnabledBy(OPT && OPT2)' ! If not explicitly set, the option is set to the value of `-OPT'. The second form specifies that the option is only set if both OPT and OPT2 are set. ! `LangEnabledBy(LANGUAGE, OPT)' ! `LangEnabledBy(LANGUAGE, OPT, POSARG, NEGARG)' When compiling for the given language, the option is set to the ! value of `-OPT', if not explicitly set. In the second form, if OPT ! is used in the positive form then POSARG is considered to be ! passed to the option, and if OPT is used in the negative form then ! NEGARG is considered to be passed to the option. It is possible ! to specify several different languages. Each LANGUAGE must have ! been declared by an earlier `Language' record. *Note Option file format::. ! `NoDWARFRecord' The option is omitted from the producer string written by ! `-grecord-gcc-switches'.  !

When an option takes an argument, it is enclosed in ! parentheses following the option property name. The parser that handles ! option files is quite simplistic, and will be tricked by any nested ! parentheses within the argument text itself; in this case, the entire ! option argument can be wrapped in curly braces within the parentheses to ! demarcate it, e.g.: Condition({defined (USE_CYGWIN_LIBSTDCXX_WRAPPERS)}) !

The theory of operation is that each pass defines a structure that ! represents everything we need to know about that pass--when it should be ! run, how it should be run, what intermediate language form or ! on-the-side data structures it needs. We register the pass to be run in ! some particular order, and the pass manager arranges for everything to ! happen in the correct order. The actuality doesn't completely live up to the theory at present. ! Command-line switches and 'timevar_id_t' enumerations must still be defined elsewhere. The pass manager validates constraints but does not attempt to (re-)generate data structures or lower intermediate language form based on the requirements of the next pass. Nevertheless, what is *************** present is useful, and a far sight bette *** 6611,6619 **** file (for GCC debugging purposes). Passes with a name starting with a star do not dump anything.

Here we do ! things like simplify `if' statements with constant conditions, remove exception handling constructs surrounding code that obviously cannot throw, remove lexical bindings that contain no variables, and other assorted simplistic cleanups. The idea is to get rid of the obvious stuff quickly rather than wait until later when it's more work to get rid of it. This pass is located in ! `tree-cfg.c' and described by `pass_remove_useless_stmts'. * Mudflap declaration registration If mudflap (*note -fmudflap -fmudflapth -fmudflapir: (gcc)Optimize Options.) is enabled, we generate code to register some variable declarations with the mudflap runtime. Specifically, the runtime ! tracks the lifetimes of those variable declarations that have ! their addresses taken, or whose bounds are unknown at compile time ! (`extern'). This pass generates new exception handling constructs ! (`try'/`finally'), and so must run before those are lowered. In addition, the pass enqueues declarations of static variables whose lifetimes extend to the entire program. The pass is located in ! `tree-mudflap.c' and is described by `pass_mudflap_1'. * OpenMP lowering ! If OpenMP generation (`-fopenmp') is enabled, this pass lowers OpenMP constructs into GIMPLE. Lowering of OpenMP constructs involves creating replacement expressions for local variables that have been mapped using data sharing clauses, exposing the control flow of most synchronization directives and adding region markers to facilitate the creation of ! the control flow graph.

The pass is located in `omp-low.c' and is ! described by `pass_expand_omp'. * Lower control flow ! This pass flattens `if' statements (`COND_EXPR') and moves lexical ! bindings (`BIND_EXPR') out of line. After this pass, all `if' ! statements will have exactly two `goto' statements in its `then' ! and `else' arms. Lexical binding information for each statement ! will be found in `TREE_BLOCK' rather than being inferred from its ! position under a `BIND_EXPR'.

After ! this pass, all `is_gimple_reg' variables will be referenced by ! `SSA_NAME', and all occurrences of other variables will be ! annotated with `VDEFS' and `VUSES'; PHI nodes will have been inserted as necessary for each basic block. This pass is located ! in `tree-ssa.c' and is described by `pass_build_ssa'. * Warn for uninitialized variables ! This pass scans the function for uses of `SSA_NAME's that are fed by default definition. For non-parameter variables, such uses are uninitialized.

It is located in `tree-ssa-phiopt.c' and is described by ! `pass_phiopt'. * May-alias optimization This pass performs a flow sensitive SSA-based points-to analysis. The resulting may-alias, must-alias, and escape analysis ! information is used to promote variables from in-memory ! addressable objects to non-aliased variables that can be renamed ! into SSA form. We also update the `VDEF'/`VUSE' memory tags for ! non-renameable aggregates so that we get fewer false kills. The ! pass is located in `tree-ssa-alias.c' and is described by ! `pass_may_alias'. Interprocedural points-to information is located in ! `tree-ssa-structalias.c' and described by `pass_ipa_pta'. * Profiling This pass rewrites the function in order to collect runtime block and value profiling data. Such data may be fed back into the compiler on a subsequent run so as to allow optimization based on ! expected execution frequencies. The pass is located in ! `predict.c' and is described by `pass_profile'. * Lower complex arithmetic This pass rewrites complex arithmetic operations into their component scalar arithmetic operations.

In the C code, machine modes are represented by an ! enumeration type, `enum machine_mode', defined in `machmode.def'. Each RTL expression has room for a machine mode and so do certain kinds of tree expressions (declarations and types, to be precise). In debugging dumps and machine descriptions, the machine mode of an RTL expression is written after the expression code with a colon to separate ! them. The letters `mode' which appear at the end of each machine mode ! name are omitted. For example, `(reg:SI 38)' is a `reg' expression ! with machine mode `SImode'. If the mode is `VOIDmode', it is not ! written at all. Here is a table of machine modes. The term "byte" below refers to an ! object of `BITS_PER_UNIT' bits (*note Storage Layout::). ! `BImode' "Bit" mode represents a single bit, for predicate registers. ! `QImode' "Quarter-Integer" mode represents a single byte treated as an integer. ! `HImode' "Half-Integer" mode represents a two-byte integer. ! `PSImode' "Partial Single Integer" mode represents an integer which occupies four bytes but which doesn't really use all four. On some machines, this is the right mode to use for pointers. ! `SImode' "Single Integer" mode represents a four-byte integer. ! `PDImode' "Partial Double Integer" mode represents an integer which occupies eight bytes but which doesn't really use all eight. On some machines, this is the right mode to use for certain pointers. ! `DImode' "Double Integer" mode represents an eight-byte integer. ! `TImode' !

"Three-Quarter-Floating" (?) mode represents a three-quarter-precision (three byte) floating point number. ! `SFmode' "Single Floating" mode represents a four byte floating point number.

In RTL, only memory references can have this mode, and only if they appear in string-move or vector instructions. On machines which have no such instructions, ! `BLKmode' will not appear in RTL. ! `VOIDmode' Void mode means the absence of a mode or an unspecified mode. For ! example, RTL expressions of code `const_int' have mode `VOIDmode' because they can be taken to have whatever mode the context ! requires. In debugging dumps of RTL, `VOIDmode' is expressed by the absence of any mode. ! `QCmode, HCmode, SCmode, DCmode, XCmode, TCmode' These modes stand for a complex number represented as a pair of ! floating point values.

File: gccint.info, Node: Constants, Next: Regs and Memory, Prev: Machine Modes, Up: RTL *************** File: gccint.info, Node: Constants, Ne *** 8565,8699 **** The simplest RTL expressions are those that represent constant values. ! `(const_int I)' This type of expression represents the integer value I. I is ! customarily accessed with the macro `INTVAL' as in `INTVAL (EXP)', ! which is equivalent to `XWINT (EXP, 0)'. Constants generated for modes with fewer bits than in ! `HOST_WIDE_INT' must be sign extended to full width (e.g., with ! `gen_int_mode'). For constants for modes with more bits than in ! `HOST_WIDE_INT' the implied high order bits of that constant are copies of the top bit. Note however that values are neither inherently signed nor inherently unsigned; where necessary, signedness is determined by the rtl operation instead. There is only one expression object for the integer value zero; it ! is the value of the variable `const0_rtx'. Likewise, the only ! expression for integer value one is found in `const1_rtx', the only ! expression for integer value two is found in `const2_rtx', and the only expression for integer value negative one is found in ! `constm1_rtx'. Any attempt to create an expression of code ! `const_int' and value zero, one, two or negative one will return ! `const0_rtx', `const1_rtx', `const2_rtx' or `constm1_rtx' as appropriate. Similarly, there is only one object for the integer whose value is ! `STORE_FLAG_VALUE'. It is found in `const_true_rtx'. If ! `STORE_FLAG_VALUE' is one, `const_true_rtx' and `const1_rtx' will ! point to the same object. If `STORE_FLAG_VALUE' is -1, ! `const_true_rtx' and `constm1_rtx' will point to the same object. ! `(const_double:M I0 I1 ...)' ! Represents either a floating-point constant of mode M or an ! integer constant too large to fit into `HOST_BITS_PER_WIDE_INT' ! bits but small enough to fit within twice that number of bits (GCC ! does not provide a mechanism to represent even larger constants). ! In the latter case, M will be `VOIDmode'. For integral values ! constants for modes with more bits than twice the number in ! `HOST_WIDE_INT' the implied high order bits of that constant are ! copies of the top bit of `CONST_DOUBLE_HIGH'. Note however that ! integral values are neither inherently signed nor inherently ! unsigned; where necessary, signedness is determined by the rtl ! operation instead. ! If M is `VOIDmode', the bits of the value are stored in I0 and I1. ! I0 is customarily accessed with the macro `CONST_DOUBLE_LOW' and ! I1 with `CONST_DOUBLE_HIGH'. If the constant is floating point (regardless of its precision), then the number of integers used to store the value depends on the ! size of `REAL_VALUE_TYPE' (*note Floating Point::). The integers represent a floating point number, but not precisely in the target ! machine's or host machine's floating point format. To convert ! them to the precise bit pattern used by the target machine, use ! the macro `REAL_VALUE_TO_TARGET_DOUBLE' and friends (*note Data Output::). ! `(const_fixed:M ...)' ! Represents a fixed-point constant of mode M. The operand is a ! data structure of type `struct fixed_value' and is accessed with ! the macro `CONST_FIXED_VALUE'. The high part of data is accessed ! with `CONST_FIXED_VALUE_HIGH'; the low part is accessed with ! `CONST_FIXED_VALUE_LOW'. ! `(const_vector:M [X0 X1 ...])' Represents a vector constant. The square brackets stand for the vector containing the constant elements. X0, X1 and so on are the ! `const_int', `const_double' or `const_fixed' elements. ! The number of units in a `const_vector' is obtained with the macro ! `CONST_VECTOR_NUNITS' as in `CONST_VECTOR_NUNITS (V)'. Individual elements in a vector constant are accessed with the ! macro `CONST_VECTOR_ELT' as in `CONST_VECTOR_ELT (V, N)' where V ! is the vector constant and N is the element desired. ! `(const_string STR)' Represents a constant string with value STR. Currently this is used only for insn attributes (*note Insn Attributes::) since constant strings in C are placed in memory. ! `(symbol_ref:MODE SYMBOL)' Represents the value of an assembler label for data. SYMBOL is a string that describes the name of the assembler label. If it ! starts with a `*', the label is the rest of SYMBOL not including ! the `*'. Otherwise, the label is SYMBOL, usually prefixed with ! `_'. ! The `symbol_ref' contains a mode, which is usually `Pmode'. Usually that is the only mode for which a symbol is directly valid. ! `(label_ref:MODE LABEL)' Represents the value of an assembler label for code. It contains ! one operand, an expression, which must be a `code_label' or a ! `note' of type `NOTE_INSN_DELETED_LABEL' that appears in the instruction sequence to identify the place where the label should go. The reason for using a distinct expression type for code label references is so that jump optimization can distinguish them. ! The `label_ref' contains a mode, which is usually `Pmode'. ! Usually that is the only mode for which a label is directly valid. ! `(const:M EXP)' Represents a constant that is the result of an assembly-time arithmetic computation. The operand, EXP, is an expression that ! contains only constants (`const_int', `symbol_ref' and `label_ref' ! expressions) combined with `plus' and `minus'. However, not all combinations are valid, since the assembler cannot do arbitrary arithmetic on relocatable symbols. ! M should be `Pmode'. ! `(high:M EXP)' ! Represents the high-order bits of EXP, usually a `symbol_ref'. ! The number of bits is machine-dependent and is normally the number ! of bits specified in an instruction that initializes the high ! order bits of a register. It is used with `lo_sum' to represent ! the typical two-instruction sequence used in RISC machines to ! reference a global memory location. ! M should be `Pmode'. ! The macro `CONST0_RTX (MODE)' refers to an expression with value 0 in ! mode MODE. If mode MODE is of mode class `MODE_INT', it returns ! `const0_rtx'. If mode MODE is of mode class `MODE_FLOAT', it returns a ! `CONST_DOUBLE' expression in mode MODE. Otherwise, it returns a ! `CONST_VECTOR' expression in mode MODE. Similarly, the macro ! `CONST1_RTX (MODE)' refers to an expression with value 1 in mode MODE ! and similarly for `CONST2_RTX'. The `CONST1_RTX' and `CONST2_RTX' macros are undefined for vector modes.  --- 8422,8555 ---- The simplest RTL expressions are those that represent constant values. ! '(const_int I)' This type of expression represents the integer value I. I is ! customarily accessed with the macro 'INTVAL' as in 'INTVAL (EXP)', ! which is equivalent to 'XWINT (EXP, 0)'. Constants generated for modes with fewer bits than in ! 'HOST_WIDE_INT' must be sign extended to full width (e.g., with ! 'gen_int_mode'). For constants for modes with more bits than in ! 'HOST_WIDE_INT' the implied high order bits of that constant are copies of the top bit. Note however that values are neither inherently signed nor inherently unsigned; where necessary, signedness is determined by the rtl operation instead. There is only one expression object for the integer value zero; it ! is the value of the variable 'const0_rtx'. Likewise, the only ! expression for integer value one is found in 'const1_rtx', the only ! expression for integer value two is found in 'const2_rtx', and the only expression for integer value negative one is found in ! 'constm1_rtx'. Any attempt to create an expression of code ! 'const_int' and value zero, one, two or negative one will return ! 'const0_rtx', 'const1_rtx', 'const2_rtx' or 'constm1_rtx' as appropriate. Similarly, there is only one object for the integer whose value is ! 'STORE_FLAG_VALUE'. It is found in 'const_true_rtx'. If ! 'STORE_FLAG_VALUE' is one, 'const_true_rtx' and 'const1_rtx' will ! point to the same object. If 'STORE_FLAG_VALUE' is -1, ! 'const_true_rtx' and 'constm1_rtx' will point to the same object. ! '(const_double:M I0 I1 ...)' ! Represents either a floating-point constant of mode M or an integer ! constant too large to fit into 'HOST_BITS_PER_WIDE_INT' bits but ! small enough to fit within twice that number of bits (GCC does not ! provide a mechanism to represent even larger constants). In the ! latter case, M will be 'VOIDmode'. For integral values constants ! for modes with more bits than twice the number in 'HOST_WIDE_INT' ! the implied high order bits of that constant are copies of the top ! bit of 'CONST_DOUBLE_HIGH'. Note however that integral values are ! neither inherently signed nor inherently unsigned; where necessary, ! signedness is determined by the rtl operation instead. ! If M is 'VOIDmode', the bits of the value are stored in I0 and I1. ! I0 is customarily accessed with the macro 'CONST_DOUBLE_LOW' and I1 ! with 'CONST_DOUBLE_HIGH'. If the constant is floating point (regardless of its precision), then the number of integers used to store the value depends on the ! size of 'REAL_VALUE_TYPE' (*note Floating Point::). The integers represent a floating point number, but not precisely in the target ! machine's or host machine's floating point format. To convert them ! to the precise bit pattern used by the target machine, use the ! macro 'REAL_VALUE_TO_TARGET_DOUBLE' and friends (*note Data Output::). ! '(const_fixed:M ...)' ! Represents a fixed-point constant of mode M. The operand is a data ! structure of type 'struct fixed_value' and is accessed with the ! macro 'CONST_FIXED_VALUE'. The high part of data is accessed with ! 'CONST_FIXED_VALUE_HIGH'; the low part is accessed with ! 'CONST_FIXED_VALUE_LOW'. ! '(const_vector:M [X0 X1 ...])' Represents a vector constant. The square brackets stand for the vector containing the constant elements. X0, X1 and so on are the ! 'const_int', 'const_double' or 'const_fixed' elements. ! The number of units in a 'const_vector' is obtained with the macro ! 'CONST_VECTOR_NUNITS' as in 'CONST_VECTOR_NUNITS (V)'. Individual elements in a vector constant are accessed with the ! macro 'CONST_VECTOR_ELT' as in 'CONST_VECTOR_ELT (V, N)' where V is ! the vector constant and N is the element desired. ! '(const_string STR)' Represents a constant string with value STR. Currently this is used only for insn attributes (*note Insn Attributes::) since constant strings in C are placed in memory. ! '(symbol_ref:MODE SYMBOL)' Represents the value of an assembler label for data. SYMBOL is a string that describes the name of the assembler label. If it ! starts with a '*', the label is the rest of SYMBOL not including ! the '*'. Otherwise, the label is SYMBOL, usually prefixed with ! '_'. ! The 'symbol_ref' contains a mode, which is usually 'Pmode'. Usually that is the only mode for which a symbol is directly valid. ! '(label_ref:MODE LABEL)' Represents the value of an assembler label for code. It contains ! one operand, an expression, which must be a 'code_label' or a ! 'note' of type 'NOTE_INSN_DELETED_LABEL' that appears in the instruction sequence to identify the place where the label should go. The reason for using a distinct expression type for code label references is so that jump optimization can distinguish them. ! The 'label_ref' contains a mode, which is usually 'Pmode'. Usually ! that is the only mode for which a label is directly valid. ! '(const:M EXP)' Represents a constant that is the result of an assembly-time arithmetic computation. The operand, EXP, is an expression that ! contains only constants ('const_int', 'symbol_ref' and 'label_ref' ! expressions) combined with 'plus' and 'minus'. However, not all combinations are valid, since the assembler cannot do arbitrary arithmetic on relocatable symbols. ! M should be 'Pmode'. ! '(high:M EXP)' ! Represents the high-order bits of EXP, usually a 'symbol_ref'. The ! number of bits is machine-dependent and is normally the number of ! bits specified in an instruction that initializes the high order ! bits of a register. It is used with 'lo_sum' to represent the ! typical two-instruction sequence used in RISC machines to reference ! a global memory location. ! M should be 'Pmode'. ! The macro 'CONST0_RTX (MODE)' refers to an expression with value 0 in ! mode MODE. If mode MODE is of mode class 'MODE_INT', it returns ! 'const0_rtx'. If mode MODE is of mode class 'MODE_FLOAT', it returns a ! 'CONST_DOUBLE' expression in mode MODE. Otherwise, it returns a ! 'CONST_VECTOR' expression in mode MODE. Similarly, the macro ! 'CONST1_RTX (MODE)' refers to an expression with value 1 in mode MODE ! and similarly for 'CONST2_RTX'. The 'CONST1_RTX' and 'CONST2_RTX' macros are undefined for vector modes.  *************** File: gccint.info, Node: Regs and Memor *** 8705,8713 **** Here are the RTL expression types for describing access to machine registers and to main memory. ! `(reg:M N)' For small values of the integer N (those that are less than ! `FIRST_PSEUDO_REGISTER'), this stands for a reference to machine register number N: a "hard register".

Similar rules apply for `PREV_INSN'. This means that the above invariants are not necessarily true for insns ! inside `sequence' expressions. Specifically, if INSN is the first insn ! in a `sequence', `NEXT_INSN (PREV_INSN (INSN))' is the insn containing ! the `sequence' expression, as is the value of `PREV_INSN (NEXT_INSN ! (INSN))' if INSN is the last insn in the `sequence' expression. You ! can use these expressions to find the containing `sequence' expression. Every insn has one of the following expression codes: ! `insn' ! The expression code `insn' is used for instructions that do not ! jump and do not do function calls. `sequence' expressions are ! always contained in insns with code `insn' even if one of those insns should jump or do function calls. ! Insns with code `insn' have four additional fields beyond the three mandatory ones listed above. These four are described in a table below. ! `jump_insn' ! The expression code `jump_insn' is used for instructions that may ! jump (or, more generally, may contain `label_ref' expressions to ! which `pc' can be set in that instruction). If there is an instruction to return from the current function, it is recorded as ! a `jump_insn'. ! `jump_insn' insns have the same extra fields as `insn' insns, accessed in the same way and in addition contain a field ! `JUMP_LABEL' which is defined once jump optimization has completed. For simple conditional and unconditional jumps, this field contains ! the `code_label' to which this insn will (possibly conditionally) ! branch. In a more complex jump, `JUMP_LABEL' records one of the labels that the insn refers to; other jump target labels are ! recorded as `REG_LABEL_TARGET' notes. The exception is `addr_vec' ! and `addr_diff_vec', where `JUMP_LABEL' is `NULL_RTX' and the only way to find the labels is to scan the entire body of the insn. Return insns count as jumps, but since they do not refer to any ! labels, their `JUMP_LABEL' is `NULL_RTX'. ! `call_insn' ! The expression code `call_insn' is used for instructions that may do function calls. It is important to distinguish these instructions because they imply that certain registers and memory locations may be altered unpredictably. ! `call_insn' insns have the same extra fields as `insn' insns, accessed in the same way and in addition contain a field ! `CALL_INSN_FUNCTION_USAGE', which contains a list (chain of ! `expr_list' expressions) containing `use', `clobber' and sometimes ! `set' expressions that denote hard registers and `mem's used or clobbered by the called function. ! A `mem' generally points to a stack slot in which arguments passed to the libcall by reference (*note TARGET_PASS_BY_REFERENCE: Register Arguments.) are stored. If the argument is caller-copied (*note TARGET_CALLEE_COPIES: Register Arguments.), the stack slot ! will be mentioned in `clobber' and `use' entries; if it's ! callee-copied, only a `use' will appear, and the `mem' may point ! to addresses that are not stack slots. ! Registers occurring inside a `clobber' in this list augment ! registers specified in `CALL_USED_REGISTERS' (*note Register Basics::). ! If the list contains a `set' involving two registers, it indicates ! that the function returns one of its arguments. Such a `set' may look like a no-op if the same register holds the argument and the return value. ! `code_label' ! A `code_label' insn represents a label that a jump insn can jump to. It contains two special fields of data in addition to the ! three standard ones. `CODE_LABEL_NUMBER' is used to hold the "label number", a number that identifies this label uniquely among all the labels in the compilation (not just in the current function). Ultimately, the label is represented in the assembler ! output as an assembler label, usually of the form `LN' where N is the label number. ! When a `code_label' appears in an RTL expression, it normally ! appears within a `label_ref' which represents the address of the label, as a number. ! Besides as a `code_label', a label can also be represented as a ! `note' of type `NOTE_INSN_DELETED_LABEL'. ! The field `LABEL_NUSES' is only defined once the jump optimization phase is completed. It contains the number of times this label is referenced in the current function. ! The field `LABEL_KIND' differentiates four different types of ! labels: `LABEL_NORMAL', `LABEL_STATIC_ENTRY', ! `LABEL_GLOBAL_ENTRY', and `LABEL_WEAK_ENTRY'. The only labels ! that do not have type `LABEL_NORMAL' are "alternate entry points" ! to the current function. These may be static (visible only in the ! containing translation unit), global (exposed to all translation ! units), or weak (global, but can be overridden by another symbol ! with the same name). Much of the compiler treats all four kinds of label identically. Some of it needs to know whether or not a label is an alternate ! entry point; for this purpose, the macro `LABEL_ALT_ENTRY_P' is ! provided. It is equivalent to testing whether `LABEL_KIND (label) == LABEL_NORMAL'. The only place that cares about the distinction between static, global, and weak alternate entry points, besides the front-end code that creates them, is the function ! `output_alternate_entry_point', in `final.c'. ! To set the kind of a label, use the `SET_LABEL_KIND' macro. ! `barrier' Barriers are placed in the instruction stream when control cannot flow past them. They are placed after unconditional jump ! instructions to indicate that the jumps are unconditional and ! after calls to `volatile' functions, which do not return (e.g., ! `exit'). They contain no information beyond the three standard ! fields. ! `note' ! `note' insns are used to represent additional debugging and declarative information. They contain two nonstandard fields, an ! integer which is accessed with the macro `NOTE_LINE_NUMBER' and a ! string accessed with `NOTE_SOURCE_FILE'. ! If `NOTE_LINE_NUMBER' is positive, the note represents the ! position of a source line and `NOTE_SOURCE_FILE' is the source ! file name that the line came from. These notes control generation ! of line number data in the assembler output. ! Otherwise, `NOTE_LINE_NUMBER' is not really a line number but a ! code with one of the following values (and `NOTE_SOURCE_FILE' must contain a null pointer): ! `NOTE_INSN_DELETED' Such a note is completely ignorable. Some passes of the compiler delete insns by altering them into notes of this kind. ! `NOTE_INSN_DELETED_LABEL' ! This marks what used to be a `code_label', but was not used ! for other purposes than taking its address and was ! transformed to mark that no code jumps to it. ! `NOTE_INSN_BLOCK_BEG' ! `NOTE_INSN_BLOCK_END' These types of notes indicate the position of the beginning ! and end of a level of scoping of variable names. They ! control the output of debugging information. ! `NOTE_INSN_EH_REGION_BEG' ! `NOTE_INSN_EH_REGION_END' These types of notes indicate the position of the beginning and end of a level of scoping for exception handling. ! `NOTE_BLOCK_NUMBER' identifies which `CODE_LABEL' or `note' ! of type `NOTE_INSN_DELETED_LABEL' is associated with the ! given region. ! `NOTE_INSN_LOOP_BEG' ! `NOTE_INSN_LOOP_END' These types of notes indicate the position of the beginning ! and end of a `while' or `for' loop. They enable the loop optimizer to find loops quickly. ! `NOTE_INSN_LOOP_CONT' ! Appears at the place in a loop that `continue' statements ! jump to. ! `NOTE_INSN_LOOP_VTOP' This note indicates the place in a loop where the exit test begins for those loops in which the exit test has been duplicated. This position becomes another virtual start of the loop when considering loop invariants. ! `NOTE_INSN_FUNCTION_BEG' Appears at the start of the function body, after the function prologue. ! `NOTE_INSN_VAR_LOCATION' This note is used to generate variable location debugging information. It indicates that the user variable in its ! `VAR_LOCATION' operand is at the location given in the RTL expression, or holds a value that can be computed by evaluating the RTL expression from that static point in the program up to the next such note for the same user variable. - These codes are printed symbolically when they appear in debugging dumps. ! `debug_insn' ! The expression code `debug_insn' is used for pseudo-instructions that hold debugging information for variable tracking at ! assignments (see `-fvar-tracking-assignments' option). They are ! the RTL representation of `GIMPLE_DEBUG' statements (*note ! `GIMPLE_DEBUG'::), with a `VAR_LOCATION' operand that binds a user ! variable tree to an RTL representation of the `value' in the ! corresponding statement. A `DEBUG_EXPR' in it stands for the ! value bound to the corresponding `DEBUG_EXPR_DECL'. Throughout optimization passes, binding information is kept in pseudo-instruction form, so that, unlike notes, it gets the same treatment and adjustments that regular instructions would. It is the variable tracking pass that turns these pseudo-instructions ! into var location notes, analyzing control flow, value ! equivalences and changes to registers and memory referenced in ! value expressions, propagating the values of debug temporaries and determining expressions that can be used to compute the value of each user variable at as many points (ranges, actually) in the program as possible. ! Unlike `NOTE_INSN_VAR_LOCATION', the value expression in an ! `INSN_VAR_LOCATION' denotes a value at that specific point in the program, rather than an expression that can be evaluated at any ! later point before an overriding `VAR_LOCATION' is encountered. ! E.g., if a user variable is bound to a `REG' and then a subsequent ! insn modifies the `REG', the note location would keep mapping the user variable to the register across the insn, whereas the insn location would keep the variable bound to the value, so that the variable tracking pass would emit another location note for the variable at the point in which the register is modified. ! ! The machine mode of an insn is normally `VOIDmode', but some phases ! use the mode for various purposes. The common subexpression elimination pass sets the mode of an insn to ! `QImode' when it is the first insn in a block that has already been processed. The second Haifa scheduling pass, for targets that can multiple issue, ! sets the mode of an insn to `TImode' when it is believed that the ! instruction begins an issue group. That is, when the instruction ! cannot issue simultaneously with the previous. This may be relied on ! by later passes, in particular machine-dependent reorg. ! Here is a table of the extra fields of `insn', `jump_insn' and ! `call_insn' insns: ! `PATTERN (I)' An expression for the side effect performed by this insn. This ! must be one of the following codes: `set', `call', `use', ! `clobber', `return', `simple_return', `asm_input', `asm_output', ! `addr_vec', `addr_diff_vec', `trap_if', `unspec', ! `unspec_volatile', `parallel', `cond_exec', or `sequence'. If it ! is a `parallel', each element of the `parallel' must be one these ! codes, except that `parallel' expressions cannot be nested and ! `addr_vec' and `addr_diff_vec' are not permitted inside a ! `parallel' expression. ! `INSN_CODE (I)' An integer that says which pattern in the machine description matches this insn, or -1 if the matching has not yet been attempted. Such matching is never attempted and this field remains -1 on an ! insn whose pattern consists of a single `use', `clobber', ! `asm_input', `addr_vec' or `addr_diff_vec' expression. ! Matching is also never attempted on insns that result from an `asm' ! statement. These contain at least one `asm_operands' expression. ! The function `asm_noperands' returns a non-negative value for such insns. ! In the debugging output, this field is printed as a number ! followed by a symbolic representation that locates the pattern in ! the `md' file as some small positive or negative offset from a ! named pattern. ! `LOG_LINKS (I)' ! A list (chain of `insn_list' expressions) giving information about dependencies between instructions within a basic block. Neither a jump nor a label may come between the related insns. These are only used by the schedulers and by combine. This is a deprecated data structure. Def-use and use-def chains are now preferred. ! `REG_NOTES (I)' ! A list (chain of `expr_list' and `insn_list' expressions) giving miscellaneous information about the insn. It is often information pertaining to the registers used in this insn. ! The `LOG_LINKS' field of an insn is a chain of `insn_list' ! expressions. Each of these has two operands: the first is an insn, and ! the second is another `insn_list' expression (the next one in the ! chain). The last `insn_list' in the chain has a null pointer as second ! operand. The significant thing about the chain is which insns appear ! in it (as first operands of `insn_list' expressions). Their order is ! not significant. This list is originally set up by the flow analysis pass; it is a null pointer until then. Flow only adds links for those data dependencies --- 10019,10315 ---- is always true. After delay slot scheduling, some of the insns in the chain might be ! 'sequence' expressions, which contain a vector of insns. The value of ! 'NEXT_INSN' in all but the last of these insns is the next insn in the ! vector; the value of 'NEXT_INSN' of the last insn in the vector is the ! same as the value of 'NEXT_INSN' for the 'sequence' in which it is ! contained. Similar rules apply for 'PREV_INSN'. This means that the above invariants are not necessarily true for insns ! inside 'sequence' expressions. Specifically, if INSN is the first insn ! in a 'sequence', 'NEXT_INSN (PREV_INSN (INSN))' is the insn containing ! the 'sequence' expression, as is the value of 'PREV_INSN (NEXT_INSN ! (INSN))' if INSN is the last insn in the 'sequence' expression. You can ! use these expressions to find the containing 'sequence' expression. Every insn has one of the following expression codes: ! 'insn' ! The expression code 'insn' is used for instructions that do not ! jump and do not do function calls. 'sequence' expressions are ! always contained in insns with code 'insn' even if one of those insns should jump or do function calls. ! Insns with code 'insn' have four additional fields beyond the three mandatory ones listed above. These four are described in a table below. ! 'jump_insn' ! The expression code 'jump_insn' is used for instructions that may ! jump (or, more generally, may contain 'label_ref' expressions to ! which 'pc' can be set in that instruction). If there is an instruction to return from the current function, it is recorded as ! a 'jump_insn'. ! 'jump_insn' insns have the same extra fields as 'insn' insns, accessed in the same way and in addition contain a field ! 'JUMP_LABEL' which is defined once jump optimization has completed. For simple conditional and unconditional jumps, this field contains ! the 'code_label' to which this insn will (possibly conditionally) ! branch. In a more complex jump, 'JUMP_LABEL' records one of the labels that the insn refers to; other jump target labels are ! recorded as 'REG_LABEL_TARGET' notes. The exception is 'addr_vec' ! and 'addr_diff_vec', where 'JUMP_LABEL' is 'NULL_RTX' and the only way to find the labels is to scan the entire body of the insn. Return insns count as jumps, but since they do not refer to any ! labels, their 'JUMP_LABEL' is 'NULL_RTX'. ! 'call_insn' ! The expression code 'call_insn' is used for instructions that may do function calls. It is important to distinguish these instructions because they imply that certain registers and memory locations may be altered unpredictably. ! 'call_insn' insns have the same extra fields as 'insn' insns, accessed in the same way and in addition contain a field ! 'CALL_INSN_FUNCTION_USAGE', which contains a list (chain of ! 'expr_list' expressions) containing 'use', 'clobber' and sometimes ! 'set' expressions that denote hard registers and 'mem's used or clobbered by the called function. ! A 'mem' generally points to a stack slot in which arguments passed to the libcall by reference (*note TARGET_PASS_BY_REFERENCE: Register Arguments.) are stored. If the argument is caller-copied (*note TARGET_CALLEE_COPIES: Register Arguments.), the stack slot ! will be mentioned in 'clobber' and 'use' entries; if it's ! callee-copied, only a 'use' will appear, and the 'mem' may point to ! addresses that are not stack slots. ! Registers occurring inside a 'clobber' in this list augment ! registers specified in 'CALL_USED_REGISTERS' (*note Register Basics::). ! If the list contains a 'set' involving two registers, it indicates ! that the function returns one of its arguments. Such a 'set' may look like a no-op if the same register holds the argument and the return value. ! 'code_label' ! A 'code_label' insn represents a label that a jump insn can jump to. It contains two special fields of data in addition to the ! three standard ones. 'CODE_LABEL_NUMBER' is used to hold the "label number", a number that identifies this label uniquely among all the labels in the compilation (not just in the current function). Ultimately, the label is represented in the assembler ! output as an assembler label, usually of the form 'LN' where N is the label number. ! When a 'code_label' appears in an RTL expression, it normally ! appears within a 'label_ref' which represents the address of the label, as a number. ! Besides as a 'code_label', a label can also be represented as a ! 'note' of type 'NOTE_INSN_DELETED_LABEL'. ! The field 'LABEL_NUSES' is only defined once the jump optimization phase is completed. It contains the number of times this label is referenced in the current function. ! The field 'LABEL_KIND' differentiates four different types of ! labels: 'LABEL_NORMAL', 'LABEL_STATIC_ENTRY', 'LABEL_GLOBAL_ENTRY', ! and 'LABEL_WEAK_ENTRY'. The only labels that do not have type ! 'LABEL_NORMAL' are "alternate entry points" to the current ! function. These may be static (visible only in the containing ! translation unit), global (exposed to all translation units), or ! weak (global, but can be overridden by another symbol with the same ! name). Much of the compiler treats all four kinds of label identically. Some of it needs to know whether or not a label is an alternate ! entry point; for this purpose, the macro 'LABEL_ALT_ENTRY_P' is ! provided. It is equivalent to testing whether 'LABEL_KIND (label) == LABEL_NORMAL'. The only place that cares about the distinction between static, global, and weak alternate entry points, besides the front-end code that creates them, is the function ! 'output_alternate_entry_point', in 'final.c'. ! To set the kind of a label, use the 'SET_LABEL_KIND' macro. ! 'barrier' Barriers are placed in the instruction stream when control cannot flow past them. They are placed after unconditional jump ! instructions to indicate that the jumps are unconditional and after ! calls to 'volatile' functions, which do not return (e.g., 'exit'). ! They contain no information beyond the three standard fields. ! 'note' ! 'note' insns are used to represent additional debugging and declarative information. They contain two nonstandard fields, an ! integer which is accessed with the macro 'NOTE_LINE_NUMBER' and a ! string accessed with 'NOTE_SOURCE_FILE'. ! If 'NOTE_LINE_NUMBER' is positive, the note represents the position ! of a source line and 'NOTE_SOURCE_FILE' is the source file name ! that the line came from. These notes control generation of line ! number data in the assembler output. ! Otherwise, 'NOTE_LINE_NUMBER' is not really a line number but a ! code with one of the following values (and 'NOTE_SOURCE_FILE' must contain a null pointer): ! 'NOTE_INSN_DELETED' Such a note is completely ignorable. Some passes of the compiler delete insns by altering them into notes of this kind. ! 'NOTE_INSN_DELETED_LABEL' ! This marks what used to be a 'code_label', but was not used ! for other purposes than taking its address and was transformed ! to mark that no code jumps to it. ! 'NOTE_INSN_BLOCK_BEG' ! 'NOTE_INSN_BLOCK_END' These types of notes indicate the position of the beginning ! and end of a level of scoping of variable names. They control ! the output of debugging information. ! 'NOTE_INSN_EH_REGION_BEG' ! 'NOTE_INSN_EH_REGION_END' These types of notes indicate the position of the beginning and end of a level of scoping for exception handling. ! 'NOTE_BLOCK_NUMBER' identifies which 'CODE_LABEL' or 'note' of ! type 'NOTE_INSN_DELETED_LABEL' is associated with the given ! region. ! 'NOTE_INSN_LOOP_BEG' ! 'NOTE_INSN_LOOP_END' These types of notes indicate the position of the beginning ! and end of a 'while' or 'for' loop. They enable the loop optimizer to find loops quickly. ! 'NOTE_INSN_LOOP_CONT' ! Appears at the place in a loop that 'continue' statements jump ! to. ! 'NOTE_INSN_LOOP_VTOP' This note indicates the place in a loop where the exit test begins for those loops in which the exit test has been duplicated. This position becomes another virtual start of the loop when considering loop invariants. ! 'NOTE_INSN_FUNCTION_BEG' Appears at the start of the function body, after the function prologue. ! 'NOTE_INSN_VAR_LOCATION' This note is used to generate variable location debugging information. It indicates that the user variable in its ! 'VAR_LOCATION' operand is at the location given in the RTL expression, or holds a value that can be computed by evaluating the RTL expression from that static point in the program up to the next such note for the same user variable. These codes are printed symbolically when they appear in debugging dumps. ! 'debug_insn' ! The expression code 'debug_insn' is used for pseudo-instructions that hold debugging information for variable tracking at ! assignments (see '-fvar-tracking-assignments' option). They are ! the RTL representation of 'GIMPLE_DEBUG' statements (*note ! 'GIMPLE_DEBUG'::), with a 'VAR_LOCATION' operand that binds a user ! variable tree to an RTL representation of the 'value' in the ! corresponding statement. A 'DEBUG_EXPR' in it stands for the value ! bound to the corresponding 'DEBUG_EXPR_DECL'. Throughout optimization passes, binding information is kept in pseudo-instruction form, so that, unlike notes, it gets the same treatment and adjustments that regular instructions would. It is the variable tracking pass that turns these pseudo-instructions ! into var location notes, analyzing control flow, value equivalences ! and changes to registers and memory referenced in value ! expressions, propagating the values of debug temporaries and determining expressions that can be used to compute the value of each user variable at as many points (ranges, actually) in the program as possible. ! Unlike 'NOTE_INSN_VAR_LOCATION', the value expression in an ! 'INSN_VAR_LOCATION' denotes a value at that specific point in the program, rather than an expression that can be evaluated at any ! later point before an overriding 'VAR_LOCATION' is encountered. ! E.g., if a user variable is bound to a 'REG' and then a subsequent ! insn modifies the 'REG', the note location would keep mapping the user variable to the register across the insn, whereas the insn location would keep the variable bound to the value, so that the variable tracking pass would emit another location note for the variable at the point in which the register is modified. ! The machine mode of an insn is normally 'VOIDmode', but some phases use ! the mode for various purposes. The common subexpression elimination pass sets the mode of an insn to !

Here is a table of the extra fields of 'insn', 'jump_insn' and ! 'call_insn' insns: ! 'PATTERN (I)' An expression for the side effect performed by this insn. This ! must be one of the following codes: 'set', 'call', 'use', ! 'clobber', 'return', 'simple_return', 'asm_input', 'asm_output', ! 'addr_vec', 'addr_diff_vec', 'trap_if', 'unspec', ! 'unspec_volatile', 'parallel', 'cond_exec', or 'sequence'. If it ! is a 'parallel', each element of the 'parallel' must be one these ! codes, except that 'parallel' expressions cannot be nested and ! 'addr_vec' and 'addr_diff_vec' are not permitted inside a ! 'parallel' expression. ! 'INSN_CODE (I)' An integer that says which pattern in the machine description matches this insn, or -1 if the matching has not yet been attempted. Such matching is never attempted and this field remains -1 on an ! insn whose pattern consists of a single 'use', 'clobber', ! 'asm_input', 'addr_vec' or 'addr_diff_vec' expression. ! Matching is also never attempted on insns that result from an 'asm' ! statement. These contain at least one 'asm_operands' expression. ! The function 'asm_noperands' returns a non-negative value for such insns. ! In the debugging output, this field is printed as a number followed ! by a symbolic representation that locates the pattern in the 'md' ! file as some small positive or negative offset from a named ! pattern. ! 'LOG_LINKS (I)' ! A list (chain of 'insn_list' expressions) giving information about dependencies between instructions within a basic block. Neither a jump nor a label may come between the related insns. These are only used by the schedulers and by combine. This is a deprecated data structure. Def-use and use-def chains are now preferred. ! 'REG_NOTES (I)' ! A list (chain of 'expr_list' and 'insn_list' expressions) giving miscellaneous information about the insn. It is often information pertaining to the registers used in this insn. ! The 'LOG_LINKS' field of an insn is a chain of 'insn_list' expressions. ! Each of these has two operands: the first is an insn, and the second is ! another 'insn_list' expression (the next one in the chain). The last ! 'insn_list' in the chain has a null pointer as second operand. The ! significant thing about the chain is which insns appear in it (as first ! operands of 'insn_list' expressions). Their order is not significant. This list is originally set up by the flow analysis pass; it is a null pointer until then.

The `REG_NOTES' field of an insn is a chain similar to the `LOG_LINKS' ! field but it includes `expr_list' expressions in addition to ! `insn_list' expressions. There are several kinds of register notes, ! which are distinguished by the machine mode, which in a register note ! is really understood as being an `enum reg_note'.

These two notes are independent; both may be present for the same register. ! `REG_INC' ! The register OP is incremented (or decremented; at this level ! there is no distinction) by an embedded side effect inside this ! insn.

A `REG_EQUIV' note is also used on an instruction which copies a register parameter into a pseudo-register at entry to a function, if there is a stack slot where that parameter could be stored.

Therefore, you may use pointer equality to compare ! 'IDENTIFIER_NODE's, rather than using a routine like 'strcmp'. Use ! 'get_identifier' to obtain the unique 'IDENTIFIER_NODE' for a supplied string. You can use the following macros to access identifiers: ! 'IDENTIFIER_POINTER' ! The string represented by the identifier, represented as a 'char*'. ! This string is always 'NUL'-terminated, and contains no embedded ! 'NUL' characters. ! 'IDENTIFIER_LENGTH' ! The length of the string returned by 'IDENTIFIER_POINTER', not ! including the trailing 'NUL'. This value of 'IDENTIFIER_LENGTH ! (x)' is always the same as 'strlen (IDENTIFIER_POINTER (x))'. !

'IDENTIFIER_TYPENAME_P' This predicate holds if the identifier represents the name of a ! user-defined conversion operator.

For the most part, different kinds of types have different tree codes. ! (For example, pointer types use a `POINTER_TYPE' code while arrays use ! an `ARRAY_TYPE' code.) However, pointers to member functions use the ! `RECORD_TYPE' code. Therefore, when writing a `switch' statement that depends on the code associated with a particular type, you should take ! care to handle pointers to member functions under the `RECORD_TYPE' ! case label. The following functions and macros deal with cv-qualification of types: ! `TYPE_MAIN_VARIANT' This macro returns the unqualified version of a type. It may be applied to an unqualified type, but it is not always the identity function in that case. A few other macros and functions are usable with all types: ! `TYPE_SIZE' The number of bits required to represent the type, represented as ! an `INTEGER_CST'. For an incomplete type, `TYPE_SIZE' will be ! `NULL_TREE'. ! `TYPE_ALIGN' ! The alignment of the type, in bits, represented as an `int'. ! `TYPE_NAME' ! This macro returns a declaration (in the form of a `TYPE_DECL') for ! the type. (Note this macro does _not_ return an ! `IDENTIFIER_NODE', as you might expect, given its name!) You can ! look at the `DECL_NAME' of the `TYPE_DECL' to obtain the actual ! name of the type. The `TYPE_NAME' will be `NULL_TREE' for a type ! that is not a built-in type, the result of a typedef, or a named ! class type. ! `TYPE_CANONICAL' This macro returns the "canonical" type for the given type node. Canonical types are used to improve performance in the C++ and Objective-C++ front ends by allowing efficient comparison between ! two type nodes in `same_type_p': if the `TYPE_CANONICAL' values of the types are equal, the types are equivalent; otherwise, the types ! are not equivalent. The notion of equivalence for canonical types is the same as the notion of type equivalence in the language ! itself. For instance, ! When `TYPE_CANONICAL' is `NULL_TREE', there is no canonical type ! for the given type node. In this case, comparison between this type and any other type requires the compiler to perform a deep, "structural" comparison to see if the two type nodes have the same form and properties. The canonical type for a node is always the most fundamental type ! in the equivalence class of types. For instance, `int' is its own ! canonical type. A typedef `I' of `int' will have `int' as its ! canonical type. Similarly, `I*' and a typedef `IP' (defined to ! `I*') will has `int*' as their canonical type. When building a new ! type node, be sure to set `TYPE_CANONICAL' to the appropriate ! canonical type. If the new type is a compound type (built from other types), and any of those other types require structural ! equality, use `SET_TYPE_STRUCTURAL_EQUALITY' to ensure that the ! new type also requires structural equality. Finally, if for some ! reason you cannot guarantee that `TYPE_CANONICAL' will point to ! the canonical type, use `SET_TYPE_STRUCTURAL_EQUALITY' to make ! sure that the new type-and any type constructed based on ! it-requires structural equality. If you suspect that the canonical ! type system is miscomparing types, pass `--param ! verify-canonical-types=1' to the compiler or configure with ! `--enable-checking' to force the compiler to verify its ! canonical-type comparisons against the structural comparisons; the ! compiler will then print any warnings if the canonical types ! miscompare. ! `TYPE_STRUCTURAL_EQUALITY_P' This predicate holds when the node requires structural equality ! checks, e.g., when `TYPE_CANONICAL' is `NULL_TREE'. ! `SET_TYPE_STRUCTURAL_EQUALITY' This macro states that the type node it is given requires ! structural equality checks, e.g., it sets `TYPE_CANONICAL' to ! `NULL_TREE'. ! `same_type_p' This predicate takes two types as input, and holds if they are the ! same type. For example, if one type is a `typedef' for the other, ! or both are `typedef's for the same type. This predicate also holds if the two trees given as input are simply copies of one another; i.e., there is no difference between them at the source level, but, for whatever reason, a duplicate has been made in the ! representation. You should never use `==' (pointer equality) to ! compare types; always use `same_type_p' instead. Detailed below are the various kinds of types, and the macros that can be used to access them. Although other kinds of types are used elsewhere in G++, the types described here are the only ones that you will encounter while examining the intermediate representation. ! `VOID_TYPE' ! Used to represent the `void' type. ! `INTEGER_TYPE' ! Used to represent the various integral types, including `char', ! `short', `int', `long', and `long long'. This code is not used ! for enumeration types, nor for the `bool' type. The ! `TYPE_PRECISION' is the number of bits used in the representation, ! represented as an `unsigned int'. (Note that in the general case ! this is not the same value as `TYPE_SIZE'; suppose that there were ! a 24-bit integer type, but that alignment requirements for the ABI ! required 32-bit alignment. Then, `TYPE_SIZE' would be an ! `INTEGER_CST' for 32, while `TYPE_PRECISION' would be 24.) The ! integer type is unsigned if `TYPE_UNSIGNED' holds; otherwise, it ! is signed. ! The `TYPE_MIN_VALUE' is an `INTEGER_CST' for the smallest integer that may be represented by this type. Similarly, the ! `TYPE_MAX_VALUE' is an `INTEGER_CST' for the largest integer that may be represented by this type. ! `REAL_TYPE' ! Used to represent the `float', `double', and `long double' types. ! The number of bits in the floating-point representation is given ! by `TYPE_PRECISION', as in the `INTEGER_TYPE' case. ! `FIXED_POINT_TYPE' ! Used to represent the `short _Fract', `_Fract', `long _Fract', ! `long long _Fract', `short _Accum', `_Accum', `long _Accum', and ! `long long _Accum' types. The number of bits in the fixed-point ! representation is given by `TYPE_PRECISION', as in the ! `INTEGER_TYPE' case. There may be padding bits, fractional bits and integral bits. The number of fractional bits is given by ! `TYPE_FBIT', and the number of integral bits is given by ! `TYPE_IBIT'. The fixed-point type is unsigned if `TYPE_UNSIGNED' ! holds; otherwise, it is signed. The fixed-point type is ! saturating if `TYPE_SATURATING' holds; otherwise, it is not ! saturating. ! `COMPLEX_TYPE' ! Used to represent GCC built-in `__complex__' data types. The ! `TREE_TYPE' is the type of the real and imaginary parts. ! `ENUMERAL_TYPE' ! Used to represent an enumeration type. The `TYPE_PRECISION' gives ! (as an `int'), the number of bits used to represent the type. If ! there are no negative enumeration constants, `TYPE_UNSIGNED' will hold. The minimum and maximum enumeration constants may be ! obtained with `TYPE_MIN_VALUE' and `TYPE_MAX_VALUE', respectively; ! each of these macros returns an `INTEGER_CST'. The actual enumeration constants themselves may be obtained by ! looking at the `TYPE_VALUES'. This macro will return a ! `TREE_LIST', containing the constants. The `TREE_PURPOSE' of each ! node will be an `IDENTIFIER_NODE' giving the name of the constant; ! the `TREE_VALUE' will be an `INTEGER_CST' giving the value ! assigned to that constant. These constants will appear in the ! order in which they were declared. The `TREE_TYPE' of each of ! these constants will be the type of enumeration type itself. ! `BOOLEAN_TYPE' ! Used to represent the `bool' type. ! `POINTER_TYPE' Used to represent pointer types, and pointer to data member types. ! The `TREE_TYPE' gives the type to which this type points. ! `REFERENCE_TYPE' ! Used to represent reference types. The `TREE_TYPE' gives the type to which this type refers. ! `FUNCTION_TYPE' Used to represent the type of non-member functions and of static ! member functions. The `TREE_TYPE' gives the return type of the ! function. The `TYPE_ARG_TYPES' are a `TREE_LIST' of the argument ! types. The `TREE_VALUE' of each node in this list is the type of ! the corresponding argument; the `TREE_PURPOSE' is an expression ! for the default argument value, if any. If the last node in the ! list is `void_list_node' (a `TREE_LIST' node whose `TREE_VALUE' is ! the `void_type_node'), then functions of this type do not take ! variable arguments. Otherwise, they do take a variable number of ! arguments. ! Note that in C (but not in C++) a function declared like `void f()' is an unprototyped function taking a variable number of arguments; ! the `TYPE_ARG_TYPES' of such a function will be `NULL'. ! `METHOD_TYPE' Used to represent the type of a non-static member function. Like a ! `FUNCTION_TYPE', the return type is given by the `TREE_TYPE'. The ! type of `*this', i.e., the class of which functions of this type ! are a member, is given by the `TYPE_METHOD_BASETYPE'. The ! `TYPE_ARG_TYPES' is the parameter list, as for a `FUNCTION_TYPE', ! and includes the `this' argument. ! `ARRAY_TYPE' ! Used to represent array types. The `TREE_TYPE' gives the type of the elements in the array. If the array-bound is present in the ! type, the `TYPE_DOMAIN' is an `INTEGER_TYPE' whose ! `TYPE_MIN_VALUE' and `TYPE_MAX_VALUE' will be the lower and upper ! bounds of the array, respectively. The `TYPE_MIN_VALUE' will ! always be an `INTEGER_CST' for zero, while the `TYPE_MAX_VALUE' ! will be one less than the number of elements in the array, i.e., ! the highest value which may be used to index an element in the ! array. ! `RECORD_TYPE' ! Used to represent `struct' and `class' types, as well as pointers to member functions and similar constructs in other languages. ! `TYPE_FIELDS' contains the items contained in this type, each of ! which can be a `FIELD_DECL', `VAR_DECL', `CONST_DECL', or ! `TYPE_DECL'. You may not make any assumptions about the ordering of the fields in the type or whether one or more of them overlap. ! `UNION_TYPE' ! Used to represent `union' types. Similar to `RECORD_TYPE' except ! that all `FIELD_DECL' nodes in `TYPE_FIELD' start at bit position zero. ! `QUAL_UNION_TYPE' Used to represent part of a variant record in Ada. Similar to ! `UNION_TYPE' except that each `FIELD_DECL' has a `DECL_QUALIFIER' field, which contains a boolean expression that indicates whether the field is present in the object. The type will only have one ! field, so each field's `DECL_QUALIFIER' is only evaluated if none ! of the expressions in the previous fields in `TYPE_FIELDS' are nonzero. Normally these expressions will reference a field in the ! outer object using a `PLACEHOLDER_EXPR'. ! `LANG_TYPE' This node is used to represent a language-specific type. The front end must handle it. ! `OFFSET_TYPE' This node is used to represent a pointer-to-data member. For a ! data member `X::m' the `TYPE_OFFSET_BASETYPE' is `X' and the ! `TREE_TYPE' is the type of `m'. ! There are variables whose values represent some of the basic types. These include: ! `void_type_node' ! A node for `void'. ! `integer_type_node' ! A node for `int'. ! `unsigned_type_node.' ! A node for `unsigned int'. ! `char_type_node.' ! A node for `char'. !

These include: ! 'DECL_NAME' ! This macro returns an 'IDENTIFIER_NODE' giving the name of the entity. ! 'TREE_TYPE' This macro returns the type of the entity declared. ! 'EXPR_FILENAME' This macro returns the name of the file in which the entity was ! declared, as a 'char*'.

'EXPR_LINENO' This macro returns the line number at which the entity was ! declared, as an 'int'. ! 'DECL_ARTIFICIAL' ! This predicate holds if the declaration was implicitly generated by ! the compiler. For example, this predicate will hold of an ! implicitly declared member function, or of the 'TYPE_DECL' implicitly generated for a class type. Recall that in C++ code like: struct S {}; is roughly equivalent to C code like: struct S {}; typedef struct S S; ! The implicitly generated 'typedef' declaration is represented by a ! 'TYPE_DECL' for which 'DECL_ARTIFICIAL' holds. The various kinds of declarations include: ! 'LABEL_DECL' These nodes are used to represent labels in function bodies.

The value ! of the constant is given by 'DECL_INITIAL' which will be an ! 'INTEGER_CST' with the same type as the 'TREE_TYPE' of the ! 'CONST_DECL', i.e., an 'ENUMERAL_TYPE'. ! 'RESULT_DECL' These nodes represent the value returned by a function. When a ! value is assigned to a 'RESULT_DECL', that indicates that the value ! should be returned, via bitwise copy, by the function. You can use ! 'DECL_SIZE' and 'DECL_ALIGN' on a 'RESULT_DECL', just as with a ! 'VAR_DECL'. ! 'TYPE_DECL' ! These nodes represent 'typedef' declarations.

'struct fixed_value' contains 'data' with the ! size of two 'HOST_BITS_PER_WIDE_INT' and 'mode' as the associated ! fixed-point machine mode for 'data'. ! 'COMPLEX_CST' ! These nodes are used to represent complex number constants, that is ! a '__complex__' whose parts are constant nodes. The ! 'TREE_REALPART' and 'TREE_IMAGPART' return the real and the imaginary parts respectively. ! 'VECTOR_CST' These nodes are used to represent vector constants, whose parts are ! constant nodes. Each individual constant node is either an integer ! or a double constant node. The first operand is a 'TREE_LIST' of ! the constant nodes and is accessed through 'TREE_VECTOR_CST_ELTS'. ! 'STRING_CST' ! These nodes represent string-constants. The 'TREE_STRING_LENGTH' ! returns the length of the string, as an 'int'. The ! 'TREE_STRING_POINTER' is a 'char*' containing the string itself. ! The string may not be 'NUL'-terminated, and it may contain embedded ! 'NUL' characters. Therefore, the 'TREE_STRING_LENGTH' includes the ! trailing 'NUL' if it is present. ! For wide string constants, the 'TREE_STRING_LENGTH' is the number ! of bytes in the string, and the 'TREE_STRING_POINTER' points to an array of the bytes of the string, as represented on the target system (that is, as integers in the target endianness). Wide and ! non-wide string constants are distinguished only by the 'TREE_TYPE' ! of the 'STRING_CST'. FIXME: The formats of string constants are not well-defined when the target system bytes are not the same width as host system bytes.

Note that the `CONST_DECL' for an enumeration constant will appear on this list, if the enumeration type ! was declared in the class.

The function members are available on the `TYPE_METHODS' list. Again, ! subsequent members are found by following the `TREE_CHAIN' field. If a function is overloaded, each of the overloaded functions appears; no ! `OVERLOAD' nodes appear on the `TYPE_METHODS' list. Implicitly ! declared functions (including default constructors, copy constructors, ! assignment operators, and destructors) will appear on this list as well. Every class has an associated "binfo", which can be obtained with ! `TYPE_BINFO'. Binfos are used to represent base-classes. The binfo ! given by `TYPE_BINFO' is the degenerate case, whereby every class is considered to be its own base-class. The base binfos for a particular binfo are held in a vector, whose length is obtained with ! `BINFO_N_BASE_BINFOS'. The base binfos themselves are obtained with ! `BINFO_BASE_BINFO' and `BINFO_BASE_ITERATE'. To add a new binfo, use ! `BINFO_BASE_APPEND'. The vector of base binfos can be obtained with ! `BINFO_BASE_BINFOS', but normally you do not need to use that. The ! class type associated with a binfo is given by `BINFO_TYPE'. It is not ! always the case that `BINFO_TYPE (TYPE_BINFO (x))', because of typedefs ! and qualified types. Neither is it the case that `TYPE_BINFO ! (BINFO_TYPE (y))' is the same binfo as `y'. The reason is that if `y' ! is a binfo representing a base-class `B' of a derived class `D', then ! `BINFO_TYPE (y)' will be `B', and `TYPE_BINFO (BINFO_TYPE (y))' will be ! `B' as its own base-class, rather than as a base-class of `D'. ! The access to a base type can be found with `BINFO_BASE_ACCESS'. This ! will produce `access_public_node', `access_private_node' or ! `access_protected_node'. If bases are always public, ! `BINFO_BASE_ACCESSES' may be `NULL'. ! `BINFO_VIRTUAL_P' is used to specify whether the binfo is inherited ! virtually or not.

A function is represented by a `FUNCTION_DECL' node. A set of ! overloaded functions is sometimes represented by an `OVERLOAD' node. ! An `OVERLOAD' node is not a declaration, so none of the `DECL_' macros ! should be used on an `OVERLOAD'. An `OVERLOAD' node is similar to a ! `TREE_LIST'. Use `OVL_CURRENT' to get the function associated with an ! `OVERLOAD' node; use `OVL_NEXT' to get the next `OVERLOAD' node in the ! list of overloaded functions. The macros `OVL_CURRENT' and `OVL_NEXT' ! are actually polymorphic; you can use them to work with `FUNCTION_DECL' ! nodes as well as with overloads. In the case of a `FUNCTION_DECL', ! `OVL_CURRENT' will always return the function itself, and `OVL_NEXT' ! will always be `NULL_TREE'. ! To determine the scope of a function, you can use the `DECL_CONTEXT' ! macro. This macro will return the class (either a `RECORD_TYPE' or a ! `UNION_TYPE') or namespace (a `NAMESPACE_DECL') of which the function ! is a member. For a virtual function, this macro returns the class in ! which the function was actually defined, not the base class in which ! the virtual declaration occurred. If a friend function is defined in a class scope, the ! `DECL_FRIEND_CONTEXT' macro can be used to determine the class in which it was defined. For example, in class C { friend void f() {} }; ! the `DECL_CONTEXT' for `f' will be the `global_namespace', but the ! `DECL_FRIEND_CONTEXT' will be the `RECORD_TYPE' for `C'. ! The following macros and functions can be used on a `FUNCTION_DECL': ! `DECL_MAIN_P' This predicate holds for a function that is the program entry point ! `::code'. ! `DECL_LOCAL_FUNCTION_P' This predicate holds if the function was declared at block scope, even though it has a global scope. ! `DECL_ANTICIPATED' This predicate holds if the function is a built-in function but its prototype is not yet explicitly declared. ! `DECL_EXTERN_C_FUNCTION_P' ! This predicate holds if the function is declared as an ``extern "C"'' function. ! `DECL_LINKONCE_P' ! This macro holds if multiple copies of this function may be ! emitted in various translation units. It is the responsibility of ! the linker to merge the various copies. Template instantiations ! are the most common example of functions for which ! `DECL_LINKONCE_P' holds; G++ instantiates needed templates in all ! translation units which require them, and then relies on the ! linker to remove duplicate instantiations. FIXME: This macro is not yet implemented. ! `DECL_FUNCTION_MEMBER_P' This macro holds if the function is a member of a class, rather than a member of a namespace. ! `DECL_STATIC_FUNCTION_P' This predicate holds if the function a static member function. ! `DECL_NONSTATIC_MEMBER_FUNCTION_P' This macro holds for a non-static member function. ! `DECL_CONST_MEMFUNC_P' ! This predicate holds for a `const'-member function. ! `DECL_VOLATILE_MEMFUNC_P' ! This predicate holds for a `volatile'-member function. ! `DECL_CONSTRUCTOR_P' This macro holds if the function is a constructor. ! `DECL_NONCONVERTING_P' This predicate holds if the constructor is a non-converting constructor. ! `DECL_COMPLETE_CONSTRUCTOR_P' This predicate holds for a function which is a constructor for an object of a complete type. ! `DECL_BASE_CONSTRUCTOR_P' This predicate holds for a function which is a constructor for a base class sub-object. ! `DECL_COPY_CONSTRUCTOR_P' This predicate holds for a function which is a copy-constructor. ! `DECL_DESTRUCTOR_P' This macro holds if the function is a destructor. ! `DECL_COMPLETE_DESTRUCTOR_P' This predicate holds if the function is the destructor for an object a complete type. ! `DECL_OVERLOADED_OPERATOR_P' This macro holds if the function is an overloaded operator. ! `DECL_CONV_FN_P' This macro holds if the function is a type-conversion operator. ! `DECL_GLOBAL_CTOR_P' This predicate holds if the function is a file-scope initialization function. ! `DECL_GLOBAL_DTOR_P' This predicate holds if the function is a file-scope finalization function. ! `DECL_THUNK_P' This predicate holds if the function is a thunk. ! These functions represent stub code that adjusts the `this' pointer and then jumps to another function. When the jumped-to function returns, control is transferred directly to the caller, without ! returning to the thunk. The first parameter to the thunk is ! always the `this' pointer; the thunk should add `THUNK_DELTA' to ! this value. (The `THUNK_DELTA' is an `int', not an `INTEGER_CST'.) ! Then, if `THUNK_VCALL_OFFSET' (an `INTEGER_CST') is nonzero the ! adjusted `this' pointer must be adjusted again. The complete calculation is given by the following pseudo-code: this += THUNK_DELTA --- 13051,13286 ---- Besides namespaces, the other high-level scoping construct in C++ is the class.

'BINFO_BASE_BINFOS', but normally you do not need to use that. The ! class type associated with a binfo is given by 'BINFO_TYPE'. It is not ! always the case that 'BINFO_TYPE (TYPE_BINFO (x))', because of typedefs ! and qualified types. Neither is it the case that 'TYPE_BINFO ! (BINFO_TYPE (y))' is the same binfo as 'y'. The reason is that if 'y' ! is a binfo representing a base-class 'B' of a derived class 'D', then ! 'BINFO_TYPE (y)' will be 'B', and 'TYPE_BINFO (BINFO_TYPE (y))' will be ! 'B' as its own base-class, rather than as a base-class of 'D'. ! The access to a base type can be found with 'BINFO_BASE_ACCESS'. This ! will produce 'access_public_node', 'access_private_node' or ! 'access_protected_node'. If bases are always public, ! 'BINFO_BASE_ACCESSES' may be 'NULL'. ! 'BINFO_VIRTUAL_P' is used to specify whether the binfo is inherited ! virtually or not. The other flags, 'BINFO_MARKED_P' and 'BINFO_FLAG_1' ! to 'BINFO_FLAG_6' can be used for language specific use. The following macros can be used on a tree node representing a class-type. ! 'LOCAL_CLASS_P' This predicate holds if the class is local class _i.e._ declared inside a function body. ! 'TYPE_POLYMORPHIC_P' This predicate holds if the class has at least one virtual function (declared or inherited). ! 'TYPE_HAS_DEFAULT_CONSTRUCTOR' This predicate holds whenever its argument represents a class-type with default constructor. ! 'CLASSTYPE_HAS_MUTABLE' ! 'TYPE_HAS_MUTABLE_P' These predicates hold for a class-type having a mutable data member. ! 'CLASSTYPE_NON_POD_P' This predicate holds only for class-types that are not PODs. ! 'TYPE_HAS_NEW_OPERATOR' ! This predicate holds for a class-type that defines 'operator new'. ! 'TYPE_HAS_ARRAY_NEW_OPERATOR' ! This predicate holds for a class-type for which 'operator new[]' is ! defined. ! 'TYPE_OVERLOADS_CALL_EXPR' This predicate holds for class-type for which the function call ! 'operator()' is overloaded. ! 'TYPE_OVERLOADS_ARRAY_REF' ! This predicate holds for a class-type that overloads 'operator[]' ! 'TYPE_OVERLOADS_ARROW' ! This predicate holds for a class-type for which 'operator->' is overloaded.  File: gccint.info, Node: Functions for C++, Next: Statements for C++, Prev: Classes, Up: C and C++ Trees 11.10.4 Functions for C++ ------------------------- ! A function is represented by a 'FUNCTION_DECL' node. A set of ! overloaded functions is sometimes represented by an 'OVERLOAD' node. ! An 'OVERLOAD' node is not a declaration, so none of the 'DECL_' macros ! should be used on an 'OVERLOAD'. An 'OVERLOAD' node is similar to a ! 'TREE_LIST'. Use 'OVL_CURRENT' to get the function associated with an ! 'OVERLOAD' node; use 'OVL_NEXT' to get the next 'OVERLOAD' node in the ! list of overloaded functions. The macros 'OVL_CURRENT' and 'OVL_NEXT' ! are actually polymorphic; you can use them to work with 'FUNCTION_DECL' ! nodes as well as with overloads. In the case of a 'FUNCTION_DECL', ! 'OVL_CURRENT' will always return the function itself, and 'OVL_NEXT' ! will always be 'NULL_TREE'. ! To determine the scope of a function, you can use the 'DECL_CONTEXT' ! macro. This macro will return the class (either a 'RECORD_TYPE' or a ! 'UNION_TYPE') or namespace (a 'NAMESPACE_DECL') of which the function is ! a member. For a virtual function, this macro returns the class in which ! the function was actually defined, not the base class in which the ! virtual declaration occurred. If a friend function is defined in a class scope, the ! 'DECL_FRIEND_CONTEXT' macro can be used to determine the class in which it was defined. For example, in class C { friend void f() {} }; ! the 'DECL_CONTEXT' for 'f' will be the 'global_namespace', but the ! 'DECL_FRIEND_CONTEXT' will be the 'RECORD_TYPE' for 'C'. ! The following macros and functions can be used on a 'FUNCTION_DECL': ! 'DECL_MAIN_P' This predicate holds for a function that is the program entry point ! '::code'. ! 'DECL_LOCAL_FUNCTION_P' This predicate holds if the function was declared at block scope, even though it has a global scope. ! 'DECL_ANTICIPATED' This predicate holds if the function is a built-in function but its prototype is not yet explicitly declared. ! 'DECL_EXTERN_C_FUNCTION_P' ! This predicate holds if the function is declared as an ''extern "C"'' function. ! 'DECL_LINKONCE_P' ! This macro holds if multiple copies of this function may be emitted ! in various translation units. It is the responsibility of the ! linker to merge the various copies. Template instantiations are ! the most common example of functions for which 'DECL_LINKONCE_P' ! holds; G++ instantiates needed templates in all translation units ! which require them, and then relies on the linker to remove ! duplicate instantiations. FIXME: This macro is not yet implemented. ! 'DECL_FUNCTION_MEMBER_P' This macro holds if the function is a member of a class, rather than a member of a namespace. ! 'DECL_STATIC_FUNCTION_P' This predicate holds if the function a static member function. ! 'DECL_NONSTATIC_MEMBER_FUNCTION_P' This macro holds for a non-static member function. ! 'DECL_CONST_MEMFUNC_P' ! This predicate holds for a 'const'-member function. ! 'DECL_VOLATILE_MEMFUNC_P' ! This predicate holds for a 'volatile'-member function. ! 'DECL_CONSTRUCTOR_P' This macro holds if the function is a constructor. ! 'DECL_NONCONVERTING_P' This predicate holds if the constructor is a non-converting constructor. ! 'DECL_COMPLETE_CONSTRUCTOR_P' This predicate holds for a function which is a constructor for an object of a complete type. ! 'DECL_BASE_CONSTRUCTOR_P' This predicate holds for a function which is a constructor for a base class sub-object. ! 'DECL_COPY_CONSTRUCTOR_P' This predicate holds for a function which is a copy-constructor. ! 'DECL_DESTRUCTOR_P' This macro holds if the function is a destructor. ! 'DECL_COMPLETE_DESTRUCTOR_P' This predicate holds if the function is the destructor for an object a complete type. ! 'DECL_OVERLOADED_OPERATOR_P' This macro holds if the function is an overloaded operator. ! 'DECL_CONV_FN_P' This macro holds if the function is a type-conversion operator. ! 'DECL_GLOBAL_CTOR_P' This predicate holds if the function is a file-scope initialization function. ! 'DECL_GLOBAL_DTOR_P' This predicate holds if the function is a file-scope finalization function. ! 'DECL_THUNK_P' This predicate holds if the function is a thunk. ! These functions represent stub code that adjusts the 'this' pointer and then jumps to another function. When the jumped-to function returns, control is transferred directly to the caller, without ! returning to the thunk. The first parameter to the thunk is always ! the 'this' pointer; the thunk should add 'THUNK_DELTA' to this ! value. (The 'THUNK_DELTA' is an 'int', not an 'INTEGER_CST'.) ! Then, if 'THUNK_VCALL_OFFSET' (an 'INTEGER_CST') is nonzero the ! adjusted 'this' pointer must be adjusted again. The complete calculation is given by the following pseudo-code: this += THUNK_DELTA *************** it was defined. For example, in *** 13455,13488 **** this += (*((ptrdiff_t **) this))[THUNK_VCALL_OFFSET] Finally, the thunk should jump to the location given by ! `DECL_INITIAL'; this will always be an expression for the address of a function. ! `DECL_NON_THUNK_FUNCTION_P' This predicate holds if the function is _not_ a thunk function. ! `GLOBAL_INIT_PRIORITY' ! If either `DECL_GLOBAL_CTOR_P' or `DECL_GLOBAL_DTOR_P' holds, then this gives the initialization priority for the function. The linker will arrange that all functions for which ! `DECL_GLOBAL_CTOR_P' holds are run in increasing order of priority ! before `main' is called. When the program exits, all functions for ! which `DECL_GLOBAL_DTOR_P' holds are run in the reverse order. ! `TYPE_RAISES_EXCEPTIONS' This macro returns the list of exceptions that a (member-)function ! can raise. The returned list, if non `NULL', is comprised of nodes ! whose `TREE_VALUE' represents a type. ! `TYPE_NOTHROW_P' This predicate holds when the exception-specification of its ! arguments is of the form ``()''. ! `DECL_ARRAY_DELETE_OPERATOR_P' !

File: gccint.info, Node: Java Trees, Prev: C and C++ Trees, Up: GENERIC *************** File: gccint.info, Node: GIMPLE, Next: *** 13733,13794 **** ********* GIMPLE is a three-address representation derived from GENERIC by ! breaking down GENERIC expressions into tuples of no more than 3 ! operands (with some exceptions like function calls). GIMPLE was ! heavily influenced by the SIMPLE IL used by the McCAT compiler project ! at McGill University, though we have made some different choices. For ! one thing, SIMPLE doesn't support `goto'. Temporaries are introduced to hold intermediate values needed to ! compute complex expressions. Additionally, all the control structures used in GENERIC are lowered into conditional jumps, lexical scopes are removed and exception regions are converted into an on the side exception region tree. The compiler pass which converts GENERIC into GIMPLE is referred to as ! the `gimplifier'. The gimplifier works recursively, generating GIMPLE tuples out of the original GENERIC expressions. One of the early implementation strategies used for the GIMPLE representation was to use the same internal data structures used by ! front ends to represent parse trees. This simplified implementation because we could leverage existing functionality and interfaces. However, GIMPLE is a much more restrictive representation than abstract syntax trees (AST), therefore it does not require the full structural complexity provided by the main tree data structure. The GENERIC representation of a function is stored in the ! `DECL_SAVED_TREE' field of the associated `FUNCTION_DECL' tree node. ! It is converted to GIMPLE by a call to `gimplify_function_tree'. If a front end wants to include language-specific tree codes in the tree representation which it provides to the back end, it must provide a ! definition of `LANG_HOOKS_GIMPLIFY_EXPR' which knows how to convert the ! front end trees to GIMPLE. Usually such a hook will involve much of ! the same code for expanding front end trees to RTL. This function can return fully lowered GIMPLE, or it can return GENERIC trees and let the main gimplifier lower them the rest of the way; this is often simpler. GIMPLE that is not fully lowered is known as "High GIMPLE" and consists ! of the IL before the pass `pass_lower_cf'. High GIMPLE contains some ! container statements like lexical scopes (represented by `GIMPLE_BIND') ! and nested expressions (e.g., `GIMPLE_TRY'), while "Low GIMPLE" exposes ! all of the implicit jumps for control and exception expressions ! directly in the IL and EH region trees. The C and C++ front ends currently convert directly from front end trees to GIMPLE, and hand that off to the back end rather than first converting to GENERIC.

You can request to dump a C-like representation of the GIMPLE form ! with the flag `-fdump-tree-gimple'. * Menu: --- 13579,13640 ---- ********* GIMPLE is a three-address representation derived from GENERIC by ! breaking down GENERIC expressions into tuples of no more than 3 operands ! (with some exceptions like function calls). GIMPLE was heavily ! influenced by the SIMPLE IL used by the McCAT compiler project at McGill ! University, though we have made some different choices. For one thing, ! SIMPLE doesn't support 'goto'. Temporaries are introduced to hold intermediate values needed to ! compute complex expressions. Additionally, all the control structures used in GENERIC are lowered into conditional jumps, lexical scopes are removed and exception regions are converted into an on the side exception region tree. The compiler pass which converts GENERIC into GIMPLE is referred to as ! the 'gimplifier'. The gimplifier works recursively, generating GIMPLE tuples out of the original GENERIC expressions. One of the early implementation strategies used for the GIMPLE representation was to use the same internal data structures used by ! front ends to represent parse trees. This simplified implementation because we could leverage existing functionality and interfaces. However, GIMPLE is a much more restrictive representation than abstract syntax trees (AST), therefore it does not require the full structural complexity provided by the main tree data structure. The GENERIC representation of a function is stored in the ! 'DECL_SAVED_TREE' field of the associated 'FUNCTION_DECL' tree node. It ! is converted to GIMPLE by a call to 'gimplify_function_tree'. If a front end wants to include language-specific tree codes in the tree representation which it provides to the back end, it must provide a ! definition of 'LANG_HOOKS_GIMPLIFY_EXPR' which knows how to convert the ! front end trees to GIMPLE. Usually such a hook will involve much of the ! same code for expanding front end trees to RTL. This function can return fully lowered GIMPLE, or it can return GENERIC trees and let the main gimplifier lower them the rest of the way; this is often simpler. GIMPLE that is not fully lowered is known as "High GIMPLE" and consists ! of the IL before the pass 'pass_lower_cf'. High GIMPLE contains some ! container statements like lexical scopes (represented by 'GIMPLE_BIND') ! and nested expressions (e.g., 'GIMPLE_TRY'), while "Low GIMPLE" exposes ! all of the implicit jumps for control and exception expressions directly ! in the IL and EH region trees. The C and C++ front ends currently convert directly from front end trees to GIMPLE, and hand that off to the back end rather than first converting to GENERIC. Their gimplifier hooks know about all the ! '_STMT' nodes and how to convert them to GENERIC forms. There was some work done on a genericization pass which would run first, but the ! existence of 'STMT_EXPR' meant that in order to convert all of the C statements into GENERIC equivalents would involve walking the entire tree anyway, so it was simpler to lower all the way. This might change in the future if someone writes an optimization pass which would work better with higher-level trees, but currently the optimizers all expect GIMPLE. ! You can request to dump a C-like representation of the GIMPLE form with ! the flag '-fdump-tree-gimple'. * Menu: *************** File: gccint.info, Node: Tuple represen *** 13810,13981 **** 12.1 Tuple representation ========================= ! GIMPLE instructions are tuples of variable size divided in two groups: ! a header describing the instruction and its locations, and a variable ! length body with all the operands. Tuples are organized into a hierarchy with 3 main classes of tuples. ! 12.1.1 `gimple_statement_base' (gsbase) --------------------------------------- This is the root of the hierarchy, it holds basic information needed by ! most GIMPLE statements. There are some fields that may not be relevant to every GIMPLE statement, but those were moved into the base structure to take advantage of holes left by other fields (thus making the structure more compact). The structure takes 4 words (32 bytes) on 64 bit hosts: Field Size (bits) ! `code' 8 ! `subcode' 16 ! `no_warning' 1 ! `visited' 1 ! `nontemporal_move' 1 ! `plf' 2 ! `modified' 1 ! `has_volatile_ops' 1 ! `references_memory_p' 1 ! `uid' 32 ! `location' 32 ! `num_ops' 32 ! `bb' 64 ! `block' 63 Total size 32 bytes ! * `code' Main identifier for a GIMPLE instruction. ! * `subcode' Used to distinguish different variants of the same basic ! instruction or provide flags applicable to a given code. The ! `subcode' flags field has different uses depending on the code of the instruction, but mostly it distinguishes instructions of the ! same family. The most prominent use of this field is in assignments, where subcode indicates the operation done on the RHS ! of the assignment. For example, a = b + c is encoded as ! `GIMPLE_ASSIGN '. ! * `no_warning' Bitflag to indicate whether a warning has already ! been issued on this statement. ! * `visited' General purpose "visited" marker. Set and cleared by each pass when needed. ! * `nontemporal_move' Bitflag used in assignments that represent non-temporal moves. Although this bitflag is only used in assignments, it was moved into the base to take advantage of the bit holes left by the previous fields. ! * `plf' Pass Local Flags. This 2-bit mask can be used as general ! purpose markers by any pass. Passes are responsible for clearing and setting these two flags accordingly. ! * `modified' Bitflag to indicate whether the statement has been modified. Used mainly by the operand scanner to determine when to re-scan a statement for operands. ! * `has_volatile_ops' Bitflag to indicate whether this statement contains operands that have been marked volatile. ! * `references_memory_p' Bitflag to indicate whether this statement contains memory references (i.e., its operands are either global variables, or pointer dereferences or anything that must reside in memory). ! * `uid' This is an unsigned integer used by passes that want to ! assign IDs to every statement. These IDs must be assigned and used by each pass. ! * `location' This is a `location_t' identifier to specify source code ! location for this statement. It is inherited from the front end. ! * `num_ops' Number of operands that this statement has. This specifies the size of the operand vector embedded in the tuple. Only used in some tuples, but it is declared in the base tuple to take advantage of the 32-bit hole left by the previous fields. ! * `bb' Basic block holding the instruction. ! * `block' Lexical block holding this statement. Also used for debug information generation. ! 12.1.2 `gimple_statement_with_ops' ---------------------------------- ! This tuple is actually split in two: `gimple_statement_with_ops_base' ! and `gimple_statement_with_ops'. This is needed to accommodate the way ! the operand vector is allocated. The operand vector is defined to be an ! array of 1 element. So, to allocate a dynamic number of operands, the ! memory allocator (`gimple_alloc') simply allocates enough memory to ! hold the structure itself plus `N - 1' operands which run "off the end" ! of the structure. For example, to allocate space for a tuple with 3 ! operands, `gimple_alloc' reserves `sizeof (struct gimple_statement_with_ops) + 2 * sizeof (tree)' bytes. On the other hand, several fields in this tuple need to be shared with ! the `gimple_statement_with_memory_ops' tuple. So, these common fields ! are placed in `gimple_statement_with_ops_base' which is then inherited from the other two tuples. ! `gsbase' 256 ! `def_ops' 64 ! `use_ops' 64 ! `op' `num_ops' * 64 !

Basic validation is ! controlled by the function `get_gimple_rhs_class', which given a tree ! code, returns an `enum' with the following values of type `enum gimple_rhs_class' ! * `GIMPLE_INVALID_RHS' The tree cannot be used as a GIMPLE operand. ! * `GIMPLE_TERNARY_RHS' The tree is a valid GIMPLE ternary operation. ! * `GIMPLE_BINARY_RHS' The tree is a valid GIMPLE binary operation. ! * `GIMPLE_UNARY_RHS' The tree is a valid GIMPLE unary operation. ! * `GIMPLE_SINGLE_RHS' The tree is a single object, that cannot be ! split into simpler operands (for instance, `SSA_NAME', `VAR_DECL', ! `COMPONENT_REF', etc). ! This operand class also acts as an escape hatch for tree nodes ! that may be flattened out into the operand vector, but would need ! more than two slots on the RHS. For instance, a `COND_EXPR' ! expression of the form `(a op b) ? x : y' could be flattened out ! on the operand vector using 4 slots, but it would also require ! additional processing to distinguish `c = a op b' from `c = a op b ! ? x : y'. Something similar occurs with `ASSERT_EXPR'. In time, ! these special case tree expressions should be flattened into the ! operand vector. ! For tree nodes in the categories `GIMPLE_TERNARY_RHS', ! `GIMPLE_BINARY_RHS' and `GIMPLE_UNARY_RHS', they cannot be stored ! inside tuples directly. They first need to be flattened and separated ! into individual components. For instance, given the GENERIC expression a = b + c --- 14047,14099 ---- 12.5.4 Logical Operators ------------------------ ! Except when they appear in the condition operand of a 'GIMPLE_COND', ! logical 'and' and 'or' operators are simplified as follows: 'a = b && c' ! becomes T1 = (bool)b; if (T1 == true) T1 = (bool)c; a = T1; !

Build a 'GIMPLE_DEBUG' statement with 'GIMPLE_DEBUG_BIND' of ! 'subcode'. The effect of this statement is to tell debug information generation machinery that the value of user variable ! 'var' is given by 'value' at that point, and to remain with that ! value until 'var' runs out of scope, a dynamically-subsequent debug ! bind statement overrides the binding, or conflicting values reach a ! control flow merge point. Even if components of the 'value' ! expression change afterwards, the variable is supposed to retain ! the same value, though not necessarily the same location. ! It is expected that 'var' be most often a tree for automatic user ! variables ('VAR_DECL' or 'PARM_DECL') that satisfy the requirements ! for gimple registers, but it may also be a tree for a scalarized ! component of a user variable ('ARRAY_REF', 'COMPONENT_REF'), or a ! debug temporary ('DEBUG_EXPR_DECL'). ! As for 'value', it can be an arbitrary tree expression, but it is recommended that it be in a suitable form for a gimple assignment ! 'RHS'. It is not expected that user variables that could appear as ! 'var' ever appear in 'value', because in the latter we'd have their ! 'SSA_NAME's instead, but even if they were not in SSA form, user ! variables appearing in 'value' are to be regarded as part of the ! executable code space, whereas those in 'var' are to be regarded as ! part of the source code space. There is no way to refer to the ! value bound to a user variable within a 'value' expression. ! If 'value' is 'GIMPLE_DEBUG_BIND_NOVALUE', debug information ! generation machinery is informed that the variable 'var' is unbound, i.e., that its value is indeterminate, which sometimes means it is really unavailable, and other times that the compiler could not keep track of it. !

In GCC, basic blocks are represented using ! the `basic_block' data type. Special basic blocks represent possible entry and exit points of a ! function. These blocks are called `ENTRY_BLOCK_PTR' and ! `EXIT_BLOCK_PTR'. These blocks do not contain any code. ! The `BASIC_BLOCK' array contains all basic blocks in an unspecified ! order. Each `basic_block' structure has a field that holds a unique ! integer identifier `index' that is the index of the block in the ! `BASIC_BLOCK' array. The total number of basic blocks in the function ! is `n_basic_blocks'. Both the basic block indices and the total number of basic blocks may vary during the compilation process, as passes ! reorder, create, duplicate, and destroy basic blocks. The index for ! any block should never be greater than `last_basic_block'. The indices ! 0 and 1 are special codes reserved for `ENTRY_BLOCK' and `EXIT_BLOCK', ! the indices of `ENTRY_BLOCK_PTR' and `EXIT_BLOCK_PTR'. ! Two pointer members of the `basic_block' structure are the pointers ! `next_bb' and `prev_bb'. These are used to keep doubly linked chain of basic blocks in the same order as the underlying instruction stream. The chain of basic blocks is updated transparently by the provided API ! for manipulating the CFG. The macro `FOR_EACH_BB' can be used to visit ! all the basic blocks in lexicographical order, except `ENTRY_BLOCK' and ! `EXIT_BLOCK'. The macro `FOR_ALL_BB' also visits all basic blocks in ! lexicographical order, including `ENTRY_BLOCK' and `EXIT_BLOCK'. ! The functions `post_order_compute' and `inverted_post_order_compute' ! can be used to compute topological orders of the CFG. The orders are ! stored as vectors of basic block indices. The `BASIC_BLOCK' array can be used to iterate each basic block by index. Dominator traversals are ! also possible using `walk_dominator_tree'.

For RTL, these pointers are `BB_HEAD' and `BB_END'.

In GCC, basic blocks are represented using the ! 'basic_block' data type. Special basic blocks represent possible entry and exit points of a ! function. These blocks are called 'ENTRY_BLOCK_PTR' and ! 'EXIT_BLOCK_PTR'. These blocks do not contain any code. ! The 'BASIC_BLOCK' array contains all basic blocks in an unspecified ! order. Each 'basic_block' structure has a field that holds a unique ! integer identifier 'index' that is the index of the block in the ! 'BASIC_BLOCK' array. The total number of basic blocks in the function ! is 'n_basic_blocks'. Both the basic block indices and the total number of basic blocks may vary during the compilation process, as passes ! reorder, create, duplicate, and destroy basic blocks. The index for any ! block should never be greater than 'last_basic_block'. The indices 0 ! and 1 are special codes reserved for 'ENTRY_BLOCK' and 'EXIT_BLOCK', the ! indices of 'ENTRY_BLOCK_PTR' and 'EXIT_BLOCK_PTR'. ! Two pointer members of the 'basic_block' structure are the pointers ! 'next_bb' and 'prev_bb'. These are used to keep doubly linked chain of basic blocks in the same order as the underlying instruction stream. The chain of basic blocks is updated transparently by the provided API ! for manipulating the CFG. The macro 'FOR_EACH_BB' can be used to visit ! all the basic blocks in lexicographical order, except 'ENTRY_BLOCK' and ! 'EXIT_BLOCK'. The macro 'FOR_ALL_BB' also visits all basic blocks in ! lexicographical order, including 'ENTRY_BLOCK' and 'EXIT_BLOCK'. ! The functions 'post_order_compute' and 'inverted_post_order_compute' ! can be used to compute topological orders of the CFG. The orders are ! stored as vectors of basic block indices. The 'BASIC_BLOCK' array can be used to iterate each basic block by index. Dominator traversals are ! also possible using 'walk_dominator_tree'. Given two basic blocks A and ! B, block A dominates block B if A is _always_ executed before B. ! Each 'basic_block' also contains pointers to the first instruction (the ! "head") and the last instruction (the "tail") or "end" of the instruction stream contained in a basic block. In fact, since the !

'struct basic_block_def'. ! For RTL, these pointers are 'BB_HEAD' and 'BB_END'.

An important task of each compiler pass is to keep both the control ! flow graph and all profile information up-to-date. Reconstruction of ! the control flow graph after each pass is not an option, since it may be very expensive and lost profile information cannot be reconstructed at all. GCC has two major intermediate representations, and both use the ! `basic_block' and `edge' data types to represent control flow. Both representations share as much of the CFG maintenance code as possible. For each representation, a set of "hooks" is defined so that each representation can provide its own implementation of CFG manipulation ! routines when necessary. These hooks are defined in `cfghooks.h'. ! There are hooks for almost all common CFG manipulations, including ! block splitting and merging, edge redirection and creating and deleting ! basic blocks. These hooks should provide everything you need to ! maintain and manipulate the CFG in both the RTL and `GIMPLE' ! representation. At the moment, the basic block boundaries are maintained transparently when modifying instructions, so there rarely is a need to move them manually (such as in case someone wants to output instruction outside basic block explicitly). ! In the RTL representation, each instruction has a `BLOCK_FOR_INSN' value that represents pointer to the basic block that contains the ! instruction. In the `GIMPLE' representation, the function `gimple_bb' returns a pointer to the basic block containing the queried statement. ! When changes need to be applied to a function in its `GIMPLE' representation, "GIMPLE statement iterators" should be used. These iterators provide an integrated abstraction of the flow graph and the ! instruction stream. Block statement iterators are constructed using ! the `gimple_stmt_iterator' data structure and several modifier are available, including the following: ! `gsi_start' ! This function initializes a `gimple_stmt_iterator' that points to the first non-empty statement in a basic block. ! `gsi_last' ! This function initializes a `gimple_stmt_iterator' that points to the last statement in a basic block. ! `gsi_end_p' ! This predicate is `true' if a `gimple_stmt_iterator' represents ! the end of a basic block. ! `gsi_next' ! This function takes a `gimple_stmt_iterator' and makes it point to its successor. ! `gsi_prev' ! This function takes a `gimple_stmt_iterator' and makes it point to its predecessor. ! `gsi_insert_after' ! This function inserts a statement after the `gimple_stmt_iterator' passed in. The final parameter determines whether the statement iterator is updated to point to the newly inserted statement, or left pointing to the original statement. ! `gsi_insert_before' ! This function inserts a statement before the `gimple_stmt_iterator' passed in. The final parameter determines whether the statement iterator is updated to point to the newly inserted statement, or ! left pointing to the original statement. ! `gsi_remove' ! This function removes the `gimple_stmt_iterator' passed in and rechains the remaining statements in a basic block, if any. ! In the RTL representation, the macros `BB_HEAD' and `BB_END' may be ! used to get the head and end `rtx' of a basic block. No abstract iterators are defined for traversing the insn chain, but you can just ! use `NEXT_INSN' and `PREV_INSN' instead. *Note Insns::. Usually a code manipulating pass simplifies the instruction stream and the flow of control, possibly eliminating some edges. This may for ! example happen when a conditional jump is replaced with an ! unconditional jump, but also when simplifying possibly trapping ! instruction to non-trapping while compiling Java.

The CFG hook `split_block' may be used when an ! instruction in the middle of a basic block has to become the target of ! a jump or branch instruction. For a global optimizer, a common operation is to split edges in the flow graph and insert instructions on them. In the RTL representation, ! this can be easily done using the `insert_insn_on_edge' function that emits an instruction "on the edge", caching it for a later ! `commit_edge_insertions' call that will take care of moving the ! inserted instructions off the edge into the instruction stream ! contained in a basic block. This includes the creation of new basic ! blocks where needed. In the `GIMPLE' representation, the equivalent ! functions are `gsi_insert_on_edge' which inserts a block statement ! iterator on an edge, and `gsi_commit_edge_inserts' which flushes the ! instruction to actual instruction stream. ! While debugging the optimization pass, the `verify_flow_info' function may be useful to find bugs in the control flow graph updating code.  --- 17740,17857 ---- 15.4 Maintaining the CFG ======================== ! An important task of each compiler pass is to keep both the control flow ! graph and all profile information up-to-date. Reconstruction of the ! control flow graph after each pass is not an option, since it may be very expensive and lost profile information cannot be reconstructed at all. GCC has two major intermediate representations, and both use the ! 'basic_block' and 'edge' data types to represent control flow. Both representations share as much of the CFG maintenance code as possible. For each representation, a set of "hooks" is defined so that each representation can provide its own implementation of CFG manipulation ! routines when necessary. These hooks are defined in 'cfghooks.h'. ! There are hooks for almost all common CFG manipulations, including block ! splitting and merging, edge redirection and creating and deleting basic ! blocks. These hooks should provide everything you need to maintain and ! manipulate the CFG in both the RTL and 'GIMPLE' representation. At the moment, the basic block boundaries are maintained transparently when modifying instructions, so there rarely is a need to move them manually (such as in case someone wants to output instruction outside basic block explicitly). ! In the RTL representation, each instruction has a 'BLOCK_FOR_INSN' value that represents pointer to the basic block that contains the ! instruction. In the 'GIMPLE' representation, the function 'gimple_bb' returns a pointer to the basic block containing the queried statement. ! When changes need to be applied to a function in its 'GIMPLE' representation, "GIMPLE statement iterators" should be used. These iterators provide an integrated abstraction of the flow graph and the ! instruction stream. Block statement iterators are constructed using the ! 'gimple_stmt_iterator' data structure and several modifier are available, including the following: ! 'gsi_start' ! This function initializes a 'gimple_stmt_iterator' that points to the first non-empty statement in a basic block. ! 'gsi_last' ! This function initializes a 'gimple_stmt_iterator' that points to the last statement in a basic block. ! 'gsi_end_p' ! This predicate is 'true' if a 'gimple_stmt_iterator' represents the ! end of a basic block. ! 'gsi_next' ! This function takes a 'gimple_stmt_iterator' and makes it point to its successor. ! 'gsi_prev' ! This function takes a 'gimple_stmt_iterator' and makes it point to its predecessor. ! 'gsi_insert_after' ! This function inserts a statement after the 'gimple_stmt_iterator' passed in. The final parameter determines whether the statement iterator is updated to point to the newly inserted statement, or left pointing to the original statement. ! 'gsi_insert_before' ! This function inserts a statement before the 'gimple_stmt_iterator' passed in. The final parameter determines whether the statement iterator is updated to point to the newly inserted statement, or ! left pointing to the original statement. ! 'gsi_remove' ! This function removes the 'gimple_stmt_iterator' passed in and rechains the remaining statements in a basic block, if any. ! In the RTL representation, the macros 'BB_HEAD' and 'BB_END' may be ! used to get the head and end 'rtx' of a basic block. No abstract iterators are defined for traversing the insn chain, but you can just ! use 'NEXT_INSN' and 'PREV_INSN' instead. *Note Insns::. Usually a code manipulating pass simplifies the instruction stream and the flow of control, possibly eliminating some edges. This may for ! example happen when a conditional jump is replaced with an unconditional ! jump, but also when simplifying possibly trapping instruction to ! non-trapping while compiling Java. Updating of edges is not transparent ! and each optimization pass is required to do so manually. However only ! few cases occur in practice. The pass may call 'purge_dead_edges' on a ! given basic block to remove superfluous edges, if any. !

"live" at given point of program, i.e. that it contains a value that ! may be used at a later point in the program. This information is used, ! for instance, during register allocation, as the pseudo registers only ! need to be assigned to a unique hard register or to a stack slot if ! they are live. The hard registers and stack slots may be freely reused ! for other values when a register is dead. Liveness information is available in the back end starting with ! `pass_df_initialize' and ending with `pass_df_finish'. Three flavors ! of live analysis are available: With `LR', it is possible to determine ! at any point `P' in the function if the register may be used on some ! path from `P' to the end of the function. With `UR', it is possible to ! determine if there is a path from the beginning of the function to `P' ! that defines the variable. `LIVE' is the intersection of the `LR' and ! `UR' and a variable is live at `P' if there is both an assignment that reaches it from the beginning of the function and a use that can be ! reached on some path from `P' to the end of the function. ! In general `LIVE' is the most useful of the three. The macros ! `DF_[LR,UR,LIVE]_[IN,OUT]' can be used to access this information. The macros take a basic block number and return a bitmap that is indexed by the register number. This information is only guaranteed to be up to ! date after calls are made to `df_analyze'. See the file `df-core.c' ! for details on using the dataflow. The liveness information is stored partly in the RTL instruction stream and partly in the flow graph. Local information is stored in the ! instruction stream: Each instruction may contain `REG_DEAD' notes representing that the value of a given register is no longer needed, or ! `REG_UNUSED' notes representing that the value computed by the instruction is never used.

Suppose that the function 'commutative_operator' is defined as follows, to match any expression whose operator is one of the commutative arithmetic operators of RTL and whose mode is MODE: *************** substitution of the operands. *** 18450,18515 **** [(match_operand:SI 1 "general_operand" "g") (match_operand:SI 2 "general_operand" "g")]) ! Here the vector `[OPERANDS...]' contains two patterns because the expressions to be matched all contain two operands. When this pattern does match, the two operands of the commutative operator are recorded as operands 1 and 2 of the insn. (This is ! done by the two instances of `match_operand'.) Operand 3 of the ! insn will be the entire commutative expression: use `GET_CODE (operands[3])' to see which commutative operator was used. ! The machine mode M of `match_operator' works like that of ! `match_operand': it is passed as the second argument to the predicate function, and that function is solely responsible for deciding whether the expression to be matched "has" that mode. When constructing an insn, argument 3 of the gen-function will ! specify the operation (i.e. the expression code) for the ! expression to be made. It should be an RTL expression, whose ! expression code is copied into a new expression whose operands are ! arguments 1 and 2 of the gen-function. The subexpressions of ! argument 3 are not used; only its expression code matters. ! When `match_operator' is used in a pattern for matching an insn, ! it usually best if the operand number of the `match_operator' is higher than that of the actual operands of the insn. This improves register allocation because the register allocator often looks at operands 1 and 2 of insns to see if it can do register tying. ! There is no way to specify constraints in `match_operator'. The ! operand of the insn which corresponds to the `match_operator' ! never has any constraints because it is never reloaded as a whole. ! However, if parts of its OPERANDS are matched by `match_operand' patterns, those parts may have constraints of their own. ! `(match_op_dup:M N[OPERANDS...])' ! Like `match_dup', except that it applies to operators instead of operands. When constructing an insn, operand number N will be ! substituted at this point. But in matching, `match_op_dup' behaves differently. It assumes that operand number N has already been ! determined by a `match_operator' appearing earlier in the recognition template, and it matches only an identical-looking expression. ! `(match_parallel N PREDICATE [SUBPAT...])' This pattern is a placeholder for an insn that consists of a ! `parallel' expression with a variable number of elements. This expression should only appear at the top level of an insn pattern. When constructing an insn, operand number N will be substituted at this point. When matching an insn, it matches if the body of the ! insn is a `parallel' expression with at least as many elements as ! the vector of SUBPAT expressions in the `match_parallel', if each !

It is the responsibility of the predicate ! to validate elements of the `parallel' beyond those listed in the ! `match_parallel'. ! A typical use of `match_parallel' is to match load and store multiple expressions, which can contain a variable number of ! elements in a `parallel'.

For example, the MIPS processor at ISA level 3 supports an ! instruction which adds two registers in 'SImode' to produce a 'DImode' result, but only if the registers are correctly sign extended. This ! predicate for the input operands accepts a 'sign_extend' of an 'SImode' ! register.

The `enabled' insn attribute may be used to disable certain insn alternatives for machine-specific reasons. This is useful when adding new instructions to an existing pattern which are only available for ! certain cpu architecture levels as specified with the `-march=' option. If an insn alternative is disabled, then it will never be used. The compiler treats the constraints for the disabled alternative as unsatisfiable. ! In order to make use of the `enabled' attribute a back end has to add in the machine description files: ! 1. A definition of the `enabled' insn attribute. The attribute is ! defined as usual using the `define_attr' command. This definition should be based on other insn attributes and/or target flags. The ! `enabled' attribute is a numeric attribute and should evaluate to ! `(const_int 1)' for an enabled alternative and to `(const_int 0)' otherwise. - 2. A definition of another insn attribute used to describe for what reason an insn alternative might be available or not. E.g. ! `cpu_facility' as in the example below. ! 3. An assignment for the second attribute to each insn definition combining instructions which are not all available under the same circumstances. (Note: It obviously only makes sense for definitions with more than one alternative. Otherwise the insn pattern should be disabled or enabled using the insn condition.) ! E.g. the following two patterns could easily be merged using the ! `enabled' attribute: (define_insn "*movdi_old" --- 19900,21470 ---- return ((unsigned long long)tickh << 32)|tickl; } !

The 'enabled' insn attribute may be used to disable certain insn alternatives for machine-specific reasons. This is useful when adding new instructions to an existing pattern which are only available for ! certain cpu architecture levels as specified with the '-march=' option. If an insn alternative is disabled, then it will never be used. The compiler treats the constraints for the disabled alternative as unsatisfiable. ! In order to make use of the 'enabled' attribute a back end has to add in the machine description files: ! 1. A definition of the 'enabled' insn attribute. The attribute is ! defined as usual using the 'define_attr' command. This definition should be based on other insn attributes and/or target flags. The ! 'enabled' attribute is a numeric attribute and should evaluate to ! '(const_int 1)' for an enabled alternative and to '(const_int 0)' otherwise. 2. A definition of another insn attribute used to describe for what reason an insn alternative might be available or not. E.g. ! 'cpu_facility' as in the example below. 3. An assignment for the second attribute to each insn definition combining instructions which are not all available under the same circumstances. (Note: It obviously only makes sense for definitions with more than one alternative. Otherwise the insn pattern should be disabled or enabled using the insn condition.) ! E.g. the following two patterns could easily be merged using the ! 'enabled' attribute: (define_insn "*movdi_old" *************** in the machine description files: *** 21816,21822 **** lgdr %0,%1" [(set_attr "cpu_facility" "*,new,new")]) ! with the `enabled' attribute defined like this: (define_attr "cpu_facility" "standard,new" (const_string "standard")) --- 21495,21501 ---- lgdr %0,%1" [(set_attr "cpu_facility" "*,new,new")]) ! with the 'enabled' attribute defined like this: (define_attr "cpu_facility" "standard,new" (const_string "standard")) *************** File: gccint.info, Node: Define Constra *** 21835,21855 **** -------------------------------------------- Machine-specific constraints fall into two categories: register and ! non-register constraints.

If you put the pseudo-Texinfo directive '@internal' at the beginning of ! a docstring, then (in the future) it will appear only in the internals ! manual's version of the machine-specific constraint tables.

The least significant half of the product is discarded. ! `umulM3_highpart' Similar, but the multiplication is unsigned. ! `maddMN4' Multiply operands 1 and 2, sign-extend them to mode N, add operand ! 3, and store the result in operand 0. Operands 1 and 2 have mode ! M and operands 0 and 3 have mode N. Both modes must be integer or fixed-point modes and N must be twice the size of M. ! In other words, `maddMN4' is like `mulMN3' except that it also ! adds operand 3. ! These instructions are not allowed to `FAIL'. ! `umaddMN4' !

Operand 1 is divided by operand 2 to produce a quotient stored in operand 0 and a remainder stored in operand 3. For machines with an instruction that produces both a quotient and ! a remainder, provide a pattern for `divmodM4' but do not provide ! patterns for `divM3' and `modM3'. This allows optimization in the relatively common case when both the quotient and remainder are computed. If an instruction that just produces a quotient or just a remainder exists and is more efficient than the instruction that produces ! both, write the output routine of `divmodM4' to call ! `find_reg_note' and look for a `REG_UNUSED' note on the quotient ! or remainder and generate the appropriate instruction. ! `udivmodM4' Similar, but does unsigned division. ! `ashlM3', `ssashlM3', `usashlM3' Arithmetic-shift operand 1 left by a number of bits specified by operand 2, and store the result in operand 0. Here M is the mode of operand 0 and operand 1; operand 2's mode is specified by the instruction pattern, and the compiler will convert the operand to that mode before generating the instruction.

The `sin' and `cos' built-in functions of C always use the mode ! which corresponds to the C data type `double' and the `sinf' and ! `cosf' built-in function use the mode which corresponds to the C ! data type `float'. Targets that can calculate the sine and cosine simultaneously can implement this pattern as opposed to ! implementing individual `sinM2' and `cosM2' patterns. The `sin' ! and `cos' built-in functions will then be expanded to the ! `sincosM3' pattern, with one of the output values left unused. ! `expM2' Store the exponential of operand 1 into operand 0. !

The `copysign' built-in function of C always uses the mode which ! corresponds to the C data type `double' and the `copysignf' built-in function uses the mode which corresponds to the C data ! type `float'. ! `ffsM2' Store into operand 0 one plus the index of the least significant 1-bit of operand 1. If operand 1 is zero, store zero. M is the mode of operand 0; operand 1's mode is specified by the instruction pattern, and the compiler will convert the operand to that mode before generating the instruction. ! The `ffs' built-in function of C always uses the mode which ! corresponds to the C data type `int'. ! `clzM2' ! Store into operand 0 the number of leading 0-bits in X, starting ! at the most significant bit position. If X is 0, the ! `CLZ_DEFINED_VALUE_AT_ZERO' (*note Misc::) macro defines if the result is undefined or has a useful value. M is the mode of operand 0; operand 1's mode is specified by the instruction pattern, and the compiler will convert the operand to that mode before generating the instruction. ! `ctzM2' Store into operand 0 the number of trailing 0-bits in X, starting at the least significant bit position.

The destination and source blocks of ! memory are the first two operands, and both are `mem:BLK's with an ! address in mode `Pmode'. The number of bytes to move is the third operand, in mode M. ! Usually, you specify `word_mode' for M. However, if you can generate better code knowing the range of valid lengths is smaller than those representable in a full word, you should provide a pattern with a mode corresponding to the range of values you can ! handle efficiently (e.g., `QImode' for values in the range 0-127; ! note we avoid numbers that appear negative) and also a pattern ! with `word_mode'. The fourth operand is the known shared alignment of the source and ! destination, in the form of a `const_int' rtx. Thus, if the compiler knows that both source and destination are word-aligned, it may provide the value 4 for this operand. Optional operands 5 and 6 specify expected alignment and size of block respectively. The expected alignment differs from alignment in operand 4 in a way that the blocks are not required to be ! aligned according to it in all cases. This expected alignment is also in bytes, just like operand 4. Expected size, when unknown, ! is set to `(const_int -1)'. ! Descriptions of multiple `movmemM' patterns can only be beneficial if the patterns for smaller modes have fewer restrictions on their first, second and fourth operands. Note that the mode M in ! `movmemM' does not impose any restriction on the mode of individually moved data units in the block. These patterns need not give special consideration to the possibility that the source and destination strings might overlap. ! `movstr' ! String copy instruction, with `stpcpy' semantics. Operand 0 is an ! output operand in mode `Pmode'. The addresses of the destination ! and source strings are operands 1 and 2, and both are `mem:BLK's ! with addresses in mode `Pmode'. The execution of the expansion of this pattern should store in operand 0 the address in which the ! `NUL' terminator was stored in the destination string. ! `setmemM' Block set instruction. The destination string is the first ! operand, given as a `mem:BLK' whose address is in mode `Pmode'. The number of bytes to set is the second operand, in mode M. The ! value to initialize the memory with is the third operand. Targets that only support the clearing of memory should reject any value ! that is not the constant 0. See `movmemM' for a discussion of the choice of mode. The fourth operand is the known alignment of the destination, in ! the form of a `const_int' rtx. Thus, if the compiler knows that the destination is word-aligned, it may provide the value 4 for this operand. Optional operands 5 and 6 specify expected alignment and size of block respectively. The expected alignment differs from alignment in operand 4 in a way that the blocks are not required to be ! aligned according to it in all cases. This expected alignment is also in bytes, just like operand 4. Expected size, when unknown, ! is set to `(const_int -1)'. ! The use for multiple `setmemM' is as for `movmemM'. ! `cmpstrnM' String compare instruction, with five operands. Operand 0 is the output; it has mode M. The remaining four operands are like the ! operands of `movmemM'. The two memory blocks specified are compared byte by byte in lexicographic order starting at the beginning of each string. The instruction is not allowed to prefetch more than one byte at a time since either string may end --- 21931,22552 ---- for a memory operand 0 and register operand 1. ! 'vec_setM' Set given field in the vector value. Operand 0 is the vector to modify, operand 1 is new value of field and operand 2 specify the field index. ! 'vec_extractM' Extract given field from the vector value. Operand 1 is the vector, operand 2 specify field index and operand 0 place to store value into. ! 'vec_initM' Initialize the vector to given values. Operand 0 is the vector to initialize and operand 1 is parallel containing values for individual fields. ! 'vcondMN' Output a conditional vector move. Operand 0 is the destination to ! receive a combination of operand 1 and operand 2, which are of mode ! M, dependent on the outcome of the predicate in operand 3 which is ! a vector comparison with operands of mode N in operands 4 and 5. ! The modes M and N should have the same size. Operand 0 will be set ! to the value OP1 & MSK | OP2 & ~MSK where MSK is computed by ! element-wise evaluation of the vector comparison with a truth value ! of all-ones and a false value of all-zeros. ! 'vec_permM' Output a (variable) vector permutation. Operand 0 is the ! destination to receive elements from operand 1 and operand 2, which ! are of mode M. Operand 3 is the "selector". It is an integral ! mode vector of the same width and number of elements as mode M. The input elements are numbered from 0 in operand 1 through 2*N-1 ! in operand 2. The elements of the selector must be computed modulo ! 2*N. Note that if 'rtx_equal_p(operand1, operand2)', this can be ! implemented with just operand 1 and selector elements modulo N. In order to make things easy for a number of targets, if there is ! no 'vec_perm' pattern for mode M, but there is for mode Q where Q ! is a vector of 'QImode' of the same width as M, the middle-end will ! lower the mode M 'VEC_PERM_EXPR' to mode Q. ! 'vec_perm_constM' ! Like 'vec_perm' except that the permutation is a compile-time ! constant. That is, operand 3, the "selector", is a 'CONST_VECTOR'. Some targets cannot perform a permutation with a variable selector, but can efficiently perform a constant permutation. Further, the ! target hook 'vec_perm_ok' is queried to determine if the specific ! constant permutation is available efficiently; the named pattern is ! never expanded without 'vec_perm_ok' returning true. ! There is no need for a target to supply both 'vec_permM' and ! 'vec_perm_constM' if the former can trivially implement the operation with, say, the vector constant loaded into a register. ! 'pushM1' Output a push instruction. Operand 0 is value to push. Used only ! when 'PUSH_ROUNDING' is defined. For historical reason, this ! pattern may be missing and in such case an 'mov' expander is used ! instead, with a 'MEM' expression forming the push operation. The ! 'mov' expander method is deprecated. ! 'addM3' Add operand 2 and operand 1, storing the result in operand 0. All operands must have mode M. This can be used even on two-address machines, by means of constraints requiring operands 1 and 0 to be the same location. ! 'ssaddM3', 'usaddM3' ! 'subM3', 'sssubM3', 'ussubM3' !

'fmaM4' Multiply operand 2 and operand 1, then add operand 3, storing the result in operand 0 without doing an intermediate rounding step. All operands must have mode M. This pattern is used to implement ! the 'fma', 'fmaf', and 'fmal' builtin functions from the ISO C99 standard. ! 'fmsM4' ! Like 'fmaM4', except operand 3 subtracted from the product instead of added to the product. This is represented in the rtl as (fma:M OP1 OP2 (neg:M OP3)) ! 'fnmaM4' ! Like 'fmaM4' except that the intermediate product is negated before ! being added to operand 3. This is represented in the rtl as (fma:M (neg:M OP1) OP2 OP3) ! 'fnmsM4' ! Like 'fmsM4' except that the intermediate product is negated before ! subtracting operand 3. This is represented in the rtl as (fma:M (neg:M OP1) OP2 (neg:M OP3)) ! 'sminM3', 'smaxM3' Signed minimum and maximum operations.

'udot_prodM' Compute the sum of the products of two signed/unsigned elements. ! Operand 1 and operand 2 are of the same mode. Their product, which ! is of a wider mode, is computed and added to operand 3. Operand 3 ! is of a mode equal or wider than the mode of the product. The ! result is placed in operand 0, which is of the same mode as operand ! 3. ! 'ssum_widenM3' ! 'usum_widenM3' ! Operands 0 and 2 are of the same mode, which is wider than the mode ! of operand 1.

Extract, convert to floating point type and widen the high/low part ! of a vector of signed/unsigned integral elements. The input vector ! (operand 1) has N elements of size S. Convert the high/low elements of the vector using floating point conversion and place the resulting N/2 values of size 2*S in the output vector (operand 0). !

'vec_widen_smult_even_M', 'vec_widen_smult_odd_M' Signed/Unsigned widening multiplication. The two inputs (operands 1 and 2) are vectors with N signed/unsigned elements of size S. Multiply the high/low or even/odd elements of the two vectors, and put the N/2 products of size 2*S in the output vector (operand 0). ! 'vec_widen_ushiftl_hi_M', 'vec_widen_ushiftl_lo_M' !

For machines with an instruction that produces both a quotient and ! a remainder, provide a pattern for 'divmodM4' but do not provide ! patterns for 'divM3' and 'modM3'. This allows optimization in the relatively common case when both the quotient and remainder are computed. If an instruction that just produces a quotient or just a remainder exists and is more efficient than the instruction that produces ! both, write the output routine of 'divmodM4' to call !

'ashlM3', 'ssashlM3', 'usashlM3' Arithmetic-shift operand 1 left by a number of bits specified by operand 2, and store the result in operand 0. Here M is the mode of operand 0 and operand 1; operand 2's mode is specified by the instruction pattern, and the compiler will convert the operand to that mode before generating the instruction. The meaning of out-of-range shift counts can optionally be specified by ! 'TARGET_SHIFT_TRUNCATION_MASK'. *Note TARGET_SHIFT_TRUNCATION_MASK::. Operand 2 is always a scalar type. !

The destination and source blocks of ! memory are the first two operands, and both are 'mem:BLK's with an ! address in mode 'Pmode'. The number of bytes to move is the third operand, in mode M. ! Usually, you specify 'word_mode' for M. However, if you can generate better code knowing the range of valid lengths is smaller than those representable in a full word, you should provide a pattern with a mode corresponding to the range of values you can ! handle efficiently (e.g., 'QImode' for values in the range 0-127; ! note we avoid numbers that appear negative) and also a pattern with ! 'word_mode'. The fourth operand is the known shared alignment of the source and ! destination, in the form of a 'const_int' rtx. Thus, if the compiler knows that both source and destination are word-aligned, it may provide the value 4 for this operand. Optional operands 5 and 6 specify expected alignment and size of block respectively. The expected alignment differs from alignment in operand 4 in a way that the blocks are not required to be ! aligned according to it in all cases. This expected alignment is also in bytes, just like operand 4. Expected size, when unknown, ! is set to '(const_int -1)'. ! Descriptions of multiple 'movmemM' patterns can only be beneficial if the patterns for smaller modes have fewer restrictions on their first, second and fourth operands. Note that the mode M in ! 'movmemM' does not impose any restriction on the mode of individually moved data units in the block. These patterns need not give special consideration to the possibility that the source and destination strings might overlap. ! 'movstr' ! String copy instruction, with 'stpcpy' semantics. Operand 0 is an ! output operand in mode 'Pmode'. The addresses of the destination ! and source strings are operands 1 and 2, and both are 'mem:BLK's ! with addresses in mode 'Pmode'.

The destination string is the first ! operand, given as a 'mem:BLK' whose address is in mode 'Pmode'. The number of bytes to set is the second operand, in mode M. The ! value to initialize the memory with is the third operand. Targets that only support the clearing of memory should reject any value ! that is not the constant 0. See 'movmemM' for a discussion of the choice of mode. The fourth operand is the known alignment of the destination, in ! the form of a 'const_int' rtx. Thus, if the compiler knows that the destination is word-aligned, it may provide the value 4 for this operand. Optional operands 5 and 6 specify expected alignment and size of block respectively. The expected alignment differs from alignment in operand 4 in a way that the blocks are not required to be ! aligned according to it in all cases. This expected alignment is also in bytes, just like operand 4. Expected size, when unknown, ! is set to '(const_int -1)'. ! The use for multiple 'setmemM' is as for 'movmemM'. !

The value stored for a true condition must have 1 as its low bit, or else must be negative. Otherwise the instruction is not suitable and you should omit it from the machine description. You describe to the compiler exactly which value is stored by defining ! the macro `STORE_FLAG_VALUE' (*note Misc::). If a description cannot be found that can be used for all the possible comparison ! operators, you should pick one and use a `define_expand' to map ! all results onto the one you chose. ! These operations may `FAIL', but should do so only in relatively ! uncommon cases; if they would `FAIL' for common cases involving integer comparisons, it is best to restrict the predicates to not allow these operands. Likewise if a given comparison operator will ! always fail, independent of the operands (for floating-point ! modes, the `ordered_comparison_operator' predicate is often useful ! in this case). If this pattern is omitted, the compiler will generate a conditional branch--for example, it may copy a constant one to the ! target and branching around an assignment of zero to the ! target--or a libcall. If the predicate for operand 1 only rejects ! some operators, it will also try reordering the operands and/or ! inverting the result value (e.g. by an exclusive OR). These possibilities could be cheaper or equivalent to the instructions ! used for the `cstoreMODE4' pattern followed by those required to ! convert a positive result from `STORE_FLAG_VALUE' to 1; in this case, you can and should make operand 1's predicate reject some ! operators in the `cstoreMODE4' pattern, or remove the pattern altogether from the machine description. ! `cbranchMODE4' Conditional branch instruction combined with a compare instruction.

The RTL generation pass generates this instruction only with constants for operands 1 and 2 and the constant is never zero for operand 1. ! This pattern is deprecated; please use 'insvM' and 'insvmisalignM' instead. ! 'movMODEcc' Conditionally move operand 2 or operand 3 into operand 0 according ! to the comparison in operand 1. If the comparison is true, operand ! 2 is moved into operand 0, otherwise operand 3 is moved. ! The mode of the operands being compared need not be the same as the ! operands being moved. Some machines, sparc64 for example, have ! instructions that conditionally move an integer value based on the ! floating point condition codes and vice versa. If the machine does not have conditional move instructions, do not define these patterns. ! 'addMODEcc' ! Similar to 'movMODEcc' but for conditional addition. Conditionally ! move operand 2 or (operands 2 + operand 3) into operand 0 according ! to the comparison in operand 1. If the comparison is false, ! operand 2 is moved into operand 0, otherwise (operand 2 + operand ! 3) is moved. ! 'cstoreMODE4' Store zero or nonzero in operand 0 according to whether a ! comparison is true. Operand 1 is a comparison operator. Operand 2 ! and operand 3 are the first and second operand of the comparison, ! respectively. You specify the mode that operand 0 must have when ! you write the 'match_operand' expression. The compiler ! automatically sees which mode you have used and supplies an operand ! of that mode. The value stored for a true condition must have 1 as its low bit, or else must be negative. Otherwise the instruction is not suitable and you should omit it from the machine description. You describe to the compiler exactly which value is stored by defining ! the macro 'STORE_FLAG_VALUE' (*note Misc::). If a description cannot be found that can be used for all the possible comparison ! operators, you should pick one and use a 'define_expand' to map all ! results onto the one you chose. ! These operations may 'FAIL', but should do so only in relatively ! uncommon cases; if they would 'FAIL' for common cases involving integer comparisons, it is best to restrict the predicates to not allow these operands. Likewise if a given comparison operator will ! always fail, independent of the operands (for floating-point modes, ! the 'ordered_comparison_operator' predicate is often useful in this ! case). If this pattern is omitted, the compiler will generate a conditional branch--for example, it may copy a constant one to the ! target and branching around an assignment of zero to the target--or ! a libcall. If the predicate for operand 1 only rejects some ! operators, it will also try reordering the operands and/or ! inverting the result value (e.g. by an exclusive OR). These possibilities could be cheaper or equivalent to the instructions ! used for the 'cstoreMODE4' pattern followed by those required to ! convert a positive result from 'STORE_FLAG_VALUE' to 1; in this case, you can and should make operand 1's predicate reject some ! operators in the 'cstoreMODE4' pattern, or remove the pattern altogether from the machine description. ! 'cbranchMODE4' Conditional branch instruction combined with a compare instruction. Operand 0 is a comparison operator. Operand 1 and operand 2 are the first and second operands of the comparison, respectively. ! Operand 3 is a 'label_ref' that refers to the label to jump to. !

Attribute value expressions must have one of the following forms: ! `(const_int I)' The integer I specifies the value of a numeric attribute. I must be non-negative. The value of a numeric attribute can be specified either with a ! `const_int', or as an integer represented as a string in ! `const_string', `eq_attr' (see below), `attr', `symbol_ref', ! simple arithmetic expressions, and `set_attr' overrides on ! specific instructions (*note Tagging Insns::). ! `(const_string VALUE)' ! The string VALUE specifies a constant attribute value. If VALUE ! is specified as `"*"', it means that the default value of the attribute is to be used for the insn containing this expression. ! `"*"' obviously cannot be used in the DEFAULT expression of a ! `define_attr'. If the attribute whose value is being specified is numeric, VALUE must be a string containing a non-negative integer (normally ! `const_int' would be used in this case). Otherwise, it must contain one of the valid values for the attribute. ! `(if_then_else TEST TRUE-VALUE FALSE-VALUE)' TEST specifies an attribute test, whose format is defined below. The value of this expression is TRUE-VALUE if TEST is true, otherwise it is FALSE-VALUE. ! `(cond [TEST1 VALUE1 ...] DEFAULT)' The first operand of this expression is a vector containing an even number of expressions and consisting of pairs of TEST and VALUE ! expressions. The value of the `cond' expression is that of the VALUE corresponding to the first true TEST expression. If none of ! the TEST expressions are true, the value of the `cond' expression is that of the DEFAULT expression. TEST expressions can have one of the following forms: ! `(const_int I)' This test is true if I is nonzero and false otherwise. ! `(not TEST)' ! `(ior TEST1 TEST2)' ! `(and TEST1 TEST2)' These tests are true if the indicated logical function is true. ! `(match_operand:M N PRED CONSTRAINTS)' !

The CONSTRAINTS operand is ignored and should be the null string. ! `(match_test C-EXPR)' The test is true if C expression C-EXPR is true.

It should normally be a global variable. ! `(eq_attr NAME VALUE)' NAME is a string specifying the name of an attribute. VALUE is a string that is either a valid value for attribute NAME, ! a comma-separated list of values, or `!' followed by a value or ! list. If VALUE does not begin with a `!', this test is true if ! the value of the NAME attribute of the current insn is in the list ! specified by VALUE.

A C statement (sans semicolon) to output to the stdio stream STREAM ! some commands that will make the label NAME weak; that is, available for reference from other files but only used if no other ! definition is available. Use the expression 'assemble_name (STREAM, NAME)' to output the name itself; before and after that, output the additional assembler syntax for making that name weak, and a newline. ! If you don't define this macro or 'ASM_WEAKEN_DECL', GCC will not ! support weak symbols and you should not define the 'SUPPORTS_WEAK' macro. -- Macro: ASM_WEAKEN_DECL (STREAM, DECL, NAME, VALUE) ! Combines (and replaces) the function of 'ASM_WEAKEN_LABEL' and ! 'ASM_OUTPUT_WEAK_ALIAS', allowing access to the associated function ! or variable decl.

If VALUE ! is 'NULL', it should output commands to make NAME weak. -- Macro: ASM_OUTPUT_WEAKREF (STREAM, DECL, NAME, VALUE) ! Outputs a directive that enables NAME to be used to refer to symbol ! VALUE with weak-symbol semantics. 'decl' is the declaration of ! 'name'. -- Macro: SUPPORTS_WEAK A preprocessor constant expression which evaluates to true if the target supports weak symbols. !

For example, for some targets GCC produces both big and little endian code. For these targets, you ! must arrange for multiple versions of `libgcc.a' to be compiled, one for each set of incompatible options. When GCC invokes the ! linker, it arranges to link in the right version of `libgcc.a', based on the command line options used. ! The `MULTILIB_OPTIONS' macro lists the set of options for which ! special versions of `libgcc.a' must be built. Write options that are mutually incompatible side by side, separated by a slash. Write options that may be used together separated by a space. The build procedure will build all combinations of compatible options. ! For example, if you set `MULTILIB_OPTIONS' to `m68000/m68020 ! msoft-float', `Makefile' will build special versions of `libgcc.a' ! using the following sets of options: `-m68000', `-m68020', ! `-msoft-float', `-m68000 -msoft-float', and `-m68020 -msoft-float'. ! `MULTILIB_DIRNAMES' ! If `MULTILIB_OPTIONS' is used, this variable specifies the directory names that should be used to hold the various libraries. ! Write one element in `MULTILIB_DIRNAMES' for each element in ! `MULTILIB_OPTIONS'. If `MULTILIB_DIRNAMES' is not used, the ! default value will be `MULTILIB_OPTIONS', with all slashes treated as spaces. ! `MULTILIB_DIRNAMES' describes the multilib directories using GCC conventions and is applied to directories that are part of the GCC installation. When multilib-enabled, the compiler will add a subdirectory of the form PREFIX/MULTILIB before each directory in the search path for libraries and crt files. ! For example, if `MULTILIB_OPTIONS' is set to `m68000/m68020 ! msoft-float', then the default value of `MULTILIB_DIRNAMES' is ! `m68000 m68020 msoft-float'. You may specify a different value if you desire a different set of directory names. ! `MULTILIB_MATCHES' ! Sometimes the same option may be written in two different ways. ! If an option is listed in `MULTILIB_OPTIONS', GCC needs to know ! about any synonyms. In that case, set `MULTILIB_MATCHES' to a ! list of items of the form `option=option' to describe all relevant ! synonyms. For example, `m68000=mc68000 m68020=mc68020'. ! `MULTILIB_EXCEPTIONS' ! Sometimes when there are multiple sets of `MULTILIB_OPTIONS' being specified, there are combinations that should not be built. In ! that case, set `MULTILIB_EXCEPTIONS' to be all of the switch exceptions in shell case syntax that should not be built. For example the ARM processor cannot execute both hardware floating point instructions and the reduced size THUMB instructions at the same time, so there is no need to build libraries with both of ! these options enabled. Therefore `MULTILIB_EXCEPTIONS' is set to: *mthumb/*mhard-float* ! `MULTILIB_REQUIRED' Sometimes when there are only a few combinations are required, it ! would be a big effort to come up with a `MULTILIB_EXCEPTIONS' list to cover all undesired ones. In such a case, just listing all the ! required combinations in `MULTILIB_REQUIRED' would be more straightforward. ! The way to specify the entries in `MULTILIB_REQUIRED' is same with ! the way used for `MULTILIB_EXCEPTIONS', only this time what are required will be specified. Suppose there are multiple sets of ! `MULTILIB_OPTIONS' and only two combinations are required, one for ARMv7-M and one for ARMv7-R with hard floating-point ABI and FPU, ! the `MULTILIB_REQUIRED' can be set to: ! `MULTILIB_REQUIRED' = mthumb/march=armv7-m ! `MULTILIB_REQUIRED' += march=armv7-r/mfloat-abi=hard/mfpu=vfpv3-d16 ! The `MULTILIB_REQUIRED' can be used together with ! `MULTILIB_EXCEPTIONS'. The option combinations generated from ! `MULTILIB_OPTIONS' will be filtered by `MULTILIB_EXCEPTIONS' and ! then by `MULTILIB_REQUIRED'. ! `MULTILIB_REUSE' Sometimes it is desirable to reuse one existing multilib for different sets of options. Such kind of reuse can minimize the number of multilib variants. And for some targets it is better to reuse an existing multilib than to fall back to default multilib when there is no corresponding multilib. This can be done by ! adding reuse rules to `MULTILIB_REUSE'. A reuse rule is comprised of two parts connected by equality sign. The left part is option set used to build multilib and the right part is option set that will reuse this multilib. The order of options in the left part matters and should be same with those ! specified in `MULTILIB_REQUIRED' or aligned with order in ! `MULTILIB_OPTIONS'. There is no such limitation for options in right part as we don't build multilib from them. But the equality sign in both parts should be replaced with period. ! The `MULTILIB_REUSE' is different from `MULTILIB_MATCHES' in that it sets up relations between two option sets rather than two options. Here is an example to demo how we reuse libraries built in Thumb mode for applications built in ARM mode: ! `MULTILIB_REUSE' = mthumb/march.armv7-r=marm/march.armv7-r ! Before the advent of `MULTILIB_REUSE', GCC select multilib by ! comparing command line options with options used to build ! multilib. The `MULTILIB_REUSE' is complementary to that way. ! Only when the original comparison matches nothing it will work to ! see if it is OK to reuse some existing multilib. ! `MULTILIB_EXTRA_OPTS' Sometimes it is desirable that when building multiple versions of ! `libgcc.a' certain options should always be passed on to the ! compiler. In that case, set `MULTILIB_EXTRA_OPTS' to be the list of options to be used for all builds. If you set this, you should ! probably set `CRTSTUFF_T_CFLAGS' to a dash followed by it. ! `MULTILIB_OSDIRNAMES' ! If `MULTILIB_OPTIONS' is used, this variable specifies a list of subdirectory names, that are used to modify the search path ! depending on the chosen multilib. Unlike `MULTILIB_DIRNAMES', ! `MULTILIB_OSDIRNAMES' describes the multilib directories using operating systems conventions, and is applied to the directories ! such as `lib' or those in the `LIBRARY_PATH' environment variable. ! The format is either the same as of `MULTILIB_DIRNAMES', or a set ! of mappings. When it is the same as `MULTILIB_DIRNAMES', it describes the multilib directories using operating system conventions, rather than GCC conventions. When it is a set of mappings of the form GCCDIR=OSDIR, the left side gives the GCC convention and the right gives the equivalent OS defined location. ! If the OSDIR part begins with a `!', GCC will not search in the non-multilib directory and use exclusively the multilib directory. Otherwise, the compiler will examine the search path for libraries and crt files twice; the first time it will add MULTILIB to each directory in the search path, the second it will not. For configurations that support both multilib and multiarch, ! `MULTILIB_OSDIRNAMES' also encodes the multiarch name, thus ! subsuming `MULTIARCH_DIRNAME'. The multiarch name is appended to each directory name, separated by a colon (e.g. ! `../lib32:i386-linux-gnu'). Each multiarch subdirectory will be searched before the corresponding OS multilib directory, for example ! `/lib/i386-linux-gnu' before `/lib/../lib32'. The multiarch name will also be used to modify the system header search path, as ! explained for `MULTIARCH_DIRNAME'. ! `MULTIARCH_DIRNAME' This variable specifies the multiarch name for configurations that are multiarch-enabled but not multilibbed configurations. --- 37423,37591 ---- Target makefile fragments can set these Makefile variables. !

'MULTILIB_OPTIONS' For some targets, invoking GCC in different ways produces objects that can not be linked together. For example, for some targets GCC produces both big and little endian code. For these targets, you ! must arrange for multiple versions of 'libgcc.a' to be compiled, one for each set of incompatible options. When GCC invokes the ! linker, it arranges to link in the right version of 'libgcc.a', based on the command line options used. ! The 'MULTILIB_OPTIONS' macro lists the set of options for which ! special versions of 'libgcc.a' must be built. Write options that are mutually incompatible side by side, separated by a slash. Write options that may be used together separated by a space. The build procedure will build all combinations of compatible options. ! For example, if you set 'MULTILIB_OPTIONS' to 'm68000/m68020 ! msoft-float', 'Makefile' will build special versions of 'libgcc.a' ! using the following sets of options: '-m68000', '-m68020', ! '-msoft-float', '-m68000 -msoft-float', and '-m68020 -msoft-float'. ! 'MULTILIB_DIRNAMES' ! If 'MULTILIB_OPTIONS' is used, this variable specifies the directory names that should be used to hold the various libraries. ! Write one element in 'MULTILIB_DIRNAMES' for each element in ! 'MULTILIB_OPTIONS'. If 'MULTILIB_DIRNAMES' is not used, the ! default value will be 'MULTILIB_OPTIONS', with all slashes treated as spaces. ! 'MULTILIB_DIRNAMES' describes the multilib directories using GCC conventions and is applied to directories that are part of the GCC installation. When multilib-enabled, the compiler will add a subdirectory of the form PREFIX/MULTILIB before each directory in the search path for libraries and crt files. ! For example, if 'MULTILIB_OPTIONS' is set to 'm68000/m68020 ! msoft-float', then the default value of 'MULTILIB_DIRNAMES' is ! 'm68000 m68020 msoft-float'. You may specify a different value if you desire a different set of directory names. ! 'MULTILIB_MATCHES' ! Sometimes the same option may be written in two different ways. If ! an option is listed in 'MULTILIB_OPTIONS', GCC needs to know about ! any synonyms. In that case, set 'MULTILIB_MATCHES' to a list of ! items of the form 'option=option' to describe all relevant ! synonyms. For example, 'm68000=mc68000 m68020=mc68020'. ! 'MULTILIB_EXCEPTIONS' ! Sometimes when there are multiple sets of 'MULTILIB_OPTIONS' being specified, there are combinations that should not be built. In ! that case, set 'MULTILIB_EXCEPTIONS' to be all of the switch exceptions in shell case syntax that should not be built. For example the ARM processor cannot execute both hardware floating point instructions and the reduced size THUMB instructions at the same time, so there is no need to build libraries with both of ! these options enabled. Therefore 'MULTILIB_EXCEPTIONS' is set to: *mthumb/*mhard-float* ! 'MULTILIB_REQUIRED' Sometimes when there are only a few combinations are required, it ! would be a big effort to come up with a 'MULTILIB_EXCEPTIONS' list to cover all undesired ones.

The problem is that propagation of inter-procedural information does ! not work well across functions and variables that are called or ! referenced by other compilation units (such as from a dynamically ! linked library). We say that such functions and variables are ! _externally visible_. To make the situation even more difficult, many applications organize themselves as a set of shared libraries, and the default ELF visibility rules allow one to overwrite any externally visible symbol with a different symbol at runtime. This basically disables any optimizations ! across such functions and variables, because the compiler cannot be ! sure that the function body it is seeing is the same function body that ! will be used at runtime. Any function or variable not declared ! `static' in the sources degrades the quality of inter-procedural ! optimization. To avoid this problem the compiler must assume that it sees the whole ! program when doing link-time optimization. Strictly speaking, the ! whole program is rarely visible even at link-time. Standard system ! libraries are usually linked dynamically or not provided with the ! link-time information. In GCC, the whole program option ! (`-fwhole-program') asserts that every function and variable defined in ! the current compilation unit is static, except for function `main' ! (note: at link time, the current unit is the union of all objects ! compiled with LTO). Since some functions and variables need to be ! referenced externally, for example by another DSO or from an assembler ! file, GCC also provides the function and variable attribute ! `externally_visible' which can be used to disable the effect of ! `-fwhole-program' on a specific symbol. The whole program mode assumptions are slightly more complex in C++, where inline functions in headers are put into _COMDAT_ sections. COMDAT function and variables can be defined by multiple object files ! and their bodies are unified at link-time and dynamic link-time. !

In addition to the many `gcc' options controlling code generation, ! `gcj' has several options specific to itself. ! `-C' ! This option is used to tell `gcj' to generate bytecode (`.class' files) rather than object code. ! `--resource RESOURCE-NAME' ! This option is used to tell `gcj' to compile the contents of a ! given file to object code so it may be accessed at runtime with ! the core protocol handler as `core:/RESOURCE-NAME'. Note that RESOURCE-NAME is the name of the resource as found at runtime; for ! instance, it could be used in a call to `ResourceBundle.getBundle'. The actual file name to be compiled this way must be specified separately. ! `-ftarget=VERSION' ! This can be used with `-C' to choose the version of bytecode ! emitted by `gcj'. The default is `1.5'. When not generating bytecode, this option has no effect. ! `-d DIRECTORY' ! When used with `-C', this causes all generated `.class' files to ! be put in the appropriate subdirectory of DIRECTORY. By default ! they will be put in subdirectories of the current working ! directory. ! `-fno-bounds-check' ! By default, `gcj' generates code which checks the bounds of all array indexing operations. With this option, these checks are omitted, which can improve performance for code that uses arrays extensively. Note that this can result in unpredictable behavior if the code in question actually does violate array bounds constraints. It is safe to use this option if you are sure that ! your code will never throw an `ArrayIndexOutOfBoundsException'. ! `-fno-store-check' Don't generate array store checks. When storing objects into arrays, a runtime check is normally generated in order to ensure ! that the object is assignment compatible with the component type ! of the array (which may not be known at compile-time). With this ! option, these checks are omitted. This can improve performance ! for code which stores objects into arrays frequently. It is safe ! to use this option if you are sure your code will never throw an ! `ArrayStoreException'. ! `-fjni' ! With `gcj' there are two options for writing native methods: CNI ! and JNI. By default `gcj' assumes you are using CNI. If you are compiling a class with native methods, and these methods are ! implemented using JNI, then you must use `-fjni'. This option ! causes `gcj' to generate stubs which will invoke the underlying JNI methods. ! `-fno-assert' ! Don't recognize the `assert' keyword. This is for compatibility with older versions of the language specification. ! `-fno-optimize-static-class-initialization' ! When the optimization level is greater or equal to `-O2', `gcj' will try to optimize the way calls into the runtime are made to initialize static classes upon their first use (this optimization ! isn't carried out if `-C' was specified.) When compiling to native ! code, `-fno-optimize-static-class-initialization' will turn this optimization off, regardless of the optimization level in use. ! `--disable-assertions[=CLASS-OR-PACKAGE]' Don't include code for checking assertions in the compiled code. ! If `=CLASS-OR-PACKAGE' is missing disables assertion code generation for all classes, unless overridden by a more specific ! `--enable-assertions' flag. If CLASS-OR-PACKAGE is a class name, ! only disables generating assertion checks within the named class ! or its inner classes. If CLASS-OR-PACKAGE is a package name, ! disables generating assertion checks within the named package or a subpackage. By default, assertions are enabled when generating class files or when not optimizing, and disabled when generating optimized binaries. ! `--enable-assertions[=CLASS-OR-PACKAGE]' Generates code to check assertions. The option is perhaps misnamed, as you still need to turn on assertion checking at run-time, and we don't support any easy way to do that. So this flag isn't very useful yet, except to partially override ! `--disable-assertions'. ! `-findirect-dispatch' ! `gcj' has a special binary compatibility ABI, which is enabled by ! the `-findirect-dispatch' option. In this mode, the code ! generated by `gcj' honors the binary compatibility guarantees in ! the Java Language Specification, and the resulting object files do ! not need to be directly linked against their dependencies. ! Instead, all dependencies are looked up at runtime. This allows ! free mixing of interpreted and compiled code. ! Note that, at present, `-findirect-dispatch' can only be used when ! compiling `.class' files. It will not work when compiling from source. CNI also does not yet work with the binary compatibility ! ABI. These restrictions will be lifted in some future release. However, if you compile CNI code with the standard ABI, you can call it from code built with the binary compatibility ABI. ! `-fbootstrap-classes' ! This option can be use to tell `libgcj' that the compiled classes should be loaded by the bootstrap loader, not the system class loader. By default, if you compile a class and link it into an ! executable, it will be treated as if it was loaded using the ! system class loader. This is convenient, as it means that things ! like `Class.forName()' will search `CLASSPATH' to find the desired class. ! `-freduced-reflection' ! This option causes the code generated by `gcj' to contain a ! reduced amount of the class meta-data used to support runtime ! reflection. The cost of this savings is the loss of the ability to ! use certain reflection capabilities of the standard Java runtime ! environment. When set all meta-data except for that which is ! needed to obtain correct runtime semantics is eliminated. ! For code that does not use reflection (i.e. serialization, RMI, ! CORBA or call methods in the `java.lang.reflect' package), ! `-freduced-reflection' will result in proper operation with a savings in executable code size. ! JNI (`-fjni') and the binary compatibility ABI ! (`-findirect-dispatch') do not work properly without full ! reflection meta-data. Because of this, it is an error to use ! these options with `-freduced-reflection'. *Caution:* If there is no reflection meta-data, code that uses a ! `SecurityManager' may not work properly. Also calling ! `Class.forName()' may fail if the calling method has no reflection meta-data. -  File: gcj.info, Node: Configure-time Options, Prev: Code Generation, Up: Invoking gcj 1.7 Configure-time Options ========================== ! Some `gcj' code generations options affect the resulting ABI, and so ! can only be meaningfully given when `libgcj', the runtime package, is ! configured. `libgcj' puts the appropriate options from this group into ! a `spec' file which is read by `gcj'. These options are listed here ! for completeness; if you are using `libgcj' then you won't want to ! touch these options. ! `-fuse-boehm-gc' This enables the use of the Boehm GC bitmap marking code. In ! particular this causes `gcj' to put an object marking descriptor into each vtable. ! `-fhash-synchronization' ! By default, synchronization data (the data used for `synchronize', ! `wait', and `notify') is pointed to by a word in each object. ! With this option `gcj' assumes that this information is stored in a ! hash table and not in the object itself. ! `-fuse-divide-subroutine' On some systems, a library routine is called to perform integer division. This is required to get exception handling correct when dividing by zero. ! `-fcheck-references' On some systems it's necessary to insert inline checks whenever accessing an object via a reference. On other systems you won't ! need this because null pointer accesses are caught automatically ! by the processor. ! `-fuse-atomic-builtins' On some systems, GCC can generate code for built-in atomic operations. Use this option to force gcj to use these builtins when compiling Java code. Where this capability is present it should be automatically detected, so you won't usually need to use this option. -  File: gcj.info, Node: Compatibility, Next: Invoking jcf-dump, Prev: Invoking gcj, Up: Top --- 1561,1743 ---- 1.6 Code Generation =================== !

When used with '-C', this causes all generated '.class' files to be ! put in the appropriate subdirectory of DIRECTORY. By default they ! will be put in subdirectories of the current working directory. ! '-fno-bounds-check' ! By default, 'gcj' generates code which checks the bounds of all array indexing operations. With this option, these checks are omitted, which can improve performance for code that uses arrays extensively. Note that this can result in unpredictable behavior if the code in question actually does violate array bounds constraints. It is safe to use this option if you are sure that ! your code will never throw an 'ArrayIndexOutOfBoundsException'. ! '-fno-store-check' Don't generate array store checks. When storing objects into arrays, a runtime check is normally generated in order to ensure ! that the object is assignment compatible with the component type of ! the array (which may not be known at compile-time). With this ! option, these checks are omitted. This can improve performance for ! code which stores objects into arrays frequently. It is safe to ! use this option if you are sure your code will never throw an ! 'ArrayStoreException'. ! '-fjni' ! With 'gcj' there are two options for writing native methods: CNI ! and JNI. By default 'gcj' assumes you are using CNI. If you are compiling a class with native methods, and these methods are ! implemented using JNI, then you must use '-fjni'. This option ! causes 'gcj' to generate stubs which will invoke the underlying JNI methods. ! '-fno-assert' ! Don't recognize the 'assert' keyword. This is for compatibility with older versions of the language specification. ! '-fno-optimize-static-class-initialization' ! When the optimization level is greater or equal to '-O2', 'gcj' will try to optimize the way calls into the runtime are made to initialize static classes upon their first use (this optimization ! isn't carried out if '-C' was specified.) When compiling to native ! code, '-fno-optimize-static-class-initialization' will turn this optimization off, regardless of the optimization level in use. ! '--disable-assertions[=CLASS-OR-PACKAGE]' Don't include code for checking assertions in the compiled code. ! If '=CLASS-OR-PACKAGE' is missing disables assertion code generation for all classes, unless overridden by a more specific ! '--enable-assertions' flag. If CLASS-OR-PACKAGE is a class name, ! only disables generating assertion checks within the named class or ! its inner classes. If CLASS-OR-PACKAGE is a package name, disables ! generating assertion checks within the named package or a subpackage. By default, assertions are enabled when generating class files or when not optimizing, and disabled when generating optimized binaries. ! '--enable-assertions[=CLASS-OR-PACKAGE]' Generates code to check assertions. The option is perhaps misnamed, as you still need to turn on assertion checking at run-time, and we don't support any easy way to do that. So this flag isn't very useful yet, except to partially override ! '--disable-assertions'. ! '-findirect-dispatch' ! 'gcj' has a special binary compatibility ABI, which is enabled by ! the '-findirect-dispatch' option. In this mode, the code generated ! by 'gcj' honors the binary compatibility guarantees in the Java ! Language Specification, and the resulting object files do not need ! to be directly linked against their dependencies. Instead, all ! dependencies are looked up at runtime. This allows free mixing of ! interpreted and compiled code. ! Note that, at present, '-findirect-dispatch' can only be used when ! compiling '.class' files. It will not work when compiling from source. CNI also does not yet work with the binary compatibility ! ABI. These restrictions will be lifted in some future release. However, if you compile CNI code with the standard ABI, you can call it from code built with the binary compatibility ABI. ! '-fbootstrap-classes' ! This option can be use to tell 'libgcj' that the compiled classes should be loaded by the bootstrap loader, not the system class loader. By default, if you compile a class and link it into an ! executable, it will be treated as if it was loaded using the system ! class loader. This is convenient, as it means that things like ! 'Class.forName()' will search 'CLASSPATH' to find the desired class. ! '-freduced-reflection' ! This option causes the code generated by 'gcj' to contain a reduced ! amount of the class meta-data used to support runtime reflection. ! The cost of this savings is the loss of the ability to use certain ! reflection capabilities of the standard Java runtime environment. ! When set all meta-data except for that which is needed to obtain ! correct runtime semantics is eliminated. ! For code that does not use reflection (i.e. serialization, RMI, ! CORBA or call methods in the 'java.lang.reflect' package), ! '-freduced-reflection' will result in proper operation with a savings in executable code size. ! JNI ('-fjni') and the binary compatibility ABI ! ('-findirect-dispatch') do not work properly without full ! reflection meta-data. Because of this, it is an error to use these ! options with '-freduced-reflection'. *Caution:* If there is no reflection meta-data, code that uses a ! 'SecurityManager' may not work properly. Also calling ! 'Class.forName()' may fail if the calling method has no reflection meta-data.  File: gcj.info, Node: Configure-time Options, Prev: Code Generation, Up: Invoking gcj 1.7 Configure-time Options ========================== ! Some 'gcj' code generations options affect the resulting ABI, and so can ! only be meaningfully given when 'libgcj', the runtime package, is ! configured. 'libgcj' puts the appropriate options from this group into ! a 'spec' file which is read by 'gcj'. These options are listed here for ! completeness; if you are using 'libgcj' then you won't want to touch ! these options. ! '-fuse-boehm-gc' This enables the use of the Boehm GC bitmap marking code. In ! particular this causes 'gcj' to put an object marking descriptor into each vtable. ! '-fhash-synchronization' ! By default, synchronization data (the data used for 'synchronize', ! 'wait', and 'notify') is pointed to by a word in each object. With ! this option 'gcj' assumes that this information is stored in a hash ! table and not in the object itself. ! '-fuse-divide-subroutine' On some systems, a library routine is called to perform integer division. This is required to get exception handling correct when dividing by zero. ! '-fcheck-references' On some systems it's necessary to insert inline checks whenever accessing an object via a reference. On other systems you won't ! need this because null pointer accesses are caught automatically by ! the processor. ! '-fuse-atomic-builtins' On some systems, GCC can generate code for built-in atomic operations. Use this option to force gcj to use these builtins when compiling Java code. Where this capability is present it should be automatically detected, so you won't usually need to use this option.

The class or binary name that was used to invoke the program. This ! will be the name of the "main" class in the case where the `gij' front end is used, or the program binary name in the case where an application is compiled to a native binary. ! `gnu.gcj.user.realname' The real name of the user, as taken from the password file. This may not always hold only the user's name (as some sites put extra information in this field). Also, this property is not available on all platforms. ! `gnu.gcj.runtime.NameFinder.use_addr2line' ! Whether an external process, `addr2line', should be used to ! determine line number information when tracing the stack. Setting ! this to `false' may suppress line numbers when printing stack traces and when using the java.util.logging infrastructure. However, performance may improve significantly for applications that print stack traces or make logging calls frequently. ! `gnu.gcj.runtime.NameFinder.show_raw' Whether the address of a stack frame should be printed when the ! line number is unavailable. Setting this to `true' will cause the name of the object and the offset within that object to be printed when no line number is available. This allows for off-line decoding of stack traces if necessary debug information is ! available. The default is `false', no raw addresses are printed. ! `gnu.gcj.runtime.NameFinder.remove_unknown' Whether stack frames for non-java code should be included in a ! stack trace. The default value is `true', stack frames for ! non-java code are suppressed. Setting this to `false' will cause any non-java stack frames to be printed in addition to frames for the java code. ! `gnu.gcj.runtime.VMClassLoader.library_control' This controls how shared libraries are automatically loaded by the ! built-in class loader. If this property is set to `full', a full search is done for each requested class. If this property is set ! to `cache', then any failed lookups are cached and not tried again. ! If this property is set to `never' (the default), then lookups are never done. For more information, *Note Extensions::. ! `gnu.gcj.runtime.endorsed.dirs' ! This is like the standard `java.endorsed.dirs', property, but specifies some extra directories which are searched after the standard endorsed directories. This is primarily useful for ! telling `libgcj' about additional libraries which are ordinarily incorporated into the JDK, and which should be loaded by the ! bootstrap class loader, but which are not yet part of `libgcj' itself for some reason. ! `gnu.gcj.jit.compiler' ! This is the full path to `gcj' executable which should be used to ! compile classes just-in-time when `ClassLoader.defineClass' is ! called. If not set, `gcj' will not be invoked by the runtime; ! this can also be controlled via `Compiler.disable'. ! `gnu.gcj.jit.options' This is a space-separated string of options which should be passed ! to `gcj' when in JIT mode. If not set, a sensible default is chosen. ! `gnu.gcj.jit.cachedir' ! This is the directory where cached shared library files are ! stored. If not set, JIT compilation is disabled.

The development goal is to provide the following features: ! * Read a user's program, stored in a file and containing ! instructions written in Fortran 77, Fortran 90, Fortran 95, ! Fortran 2003 or Fortran 2008. This file contains "source code". ! * Translate the user's program into instructions a computer can ! carry out more quickly than it takes to translate the instructions ! in the first place. The result after compilation of a program is ! "machine code", code designed to be efficiently translated and ! processed by a machine such as your computer. Humans usually are ! not as good writing machine code as they are at writing Fortran ! (or C++, Ada, or Java), because it is easy to make tiny mistakes ! writing machine code. * Provide the user with information about the reasons why the compiler is unable to create a binary from the source code. Usually this will be the case if the source code is flawed. The Fortran 90 standard requires that the compiler can point out ! mistakes to the user. An incorrect usage of the language causes ! an "error message". The compiler will also attempt to diagnose cases where the user's ! program contains a correct usage of the language, but instructs ! the computer to do something questionable. This kind of ! diagnostics message is called a "warning message". * Provide optional information about the translation passes from the source code to machine code. This can help a user of the compiler to find the cause of certain bugs which may not be obvious in the ! source code, but may be more easily found at a lower level ! compiler output. It also helps developers to find bugs in the ! compiler itself. * Provide information in the generated machine code that can make it easier to find bugs in the program (using a debugging tool, called ! a "debugger", such as the GNU Debugger `gdb'). ! * Locate and gather machine code already generated to perform ! actions requested by statements in the user's program. This ! machine code is organized into "modules" and is located and ! "linked" to the user program. The GNU Fortran compiler consists of several components: ! * A version of the `gcc' command (which also might be installed as ! the system's `cc' command) that also understands and accepts ! Fortran source code. The `gcc' command is the "driver" program for ! all the languages in the GNU Compiler Collection (GCC); With `gcc', you can compile the source code of any language for which a front end is available in GCC. ! * The `gfortran' command itself, which also might be installed as the ! system's `f95' command. `gfortran' is just another driver program, but specifically for the Fortran compiler only. The difference ! with `gcc' is that `gfortran' will automatically link the correct libraries to your program. * A collection of run-time libraries. These libraries contain the ! machine code needed to support capabilities of the Fortran ! language that are not directly provided by the machine code ! generated by the `gfortran' compilation phase, such as intrinsic ! functions and subroutines, and routines for interaction with files ! and the operating system. ! * The Fortran compiler itself, (`f951'). This is the GNU Fortran parser and code generator, linked to and interfaced with the GCC ! backend library. `f951' "translates" the source code to assembler code. You would typically not use this program directly; instead, ! the `gcc' or `gfortran' driver programs will call it for you.

This file contains "source code". ! * Translate the user's program into instructions a computer can carry ! out more quickly than it takes to translate the instructions in the ! first place. The result after compilation of a program is "machine ! code", code designed to be efficiently translated and processed by ! a machine such as your computer. Humans usually are not as good ! writing machine code as they are at writing Fortran (or C++, Ada, ! or Java), because it is easy to make tiny mistakes writing machine ! code. * Provide the user with information about the reasons why the compiler is unable to create a binary from the source code. Usually this will be the case if the source code is flawed. The Fortran 90 standard requires that the compiler can point out ! mistakes to the user. An incorrect usage of the language causes an ! "error message". The compiler will also attempt to diagnose cases where the user's ! program contains a correct usage of the language, but instructs the ! computer to do something questionable. This kind of diagnostics ! message is called a "warning message". * Provide optional information about the translation passes from the source code to machine code. This can help a user of the compiler to find the cause of certain bugs which may not be obvious in the ! source code, but may be more easily found at a lower level compiler ! output. It also helps developers to find bugs in the compiler ! itself. * Provide information in the generated machine code that can make it easier to find bugs in the program (using a debugging tool, called ! a "debugger", such as the GNU Debugger 'gdb'). ! * Locate and gather machine code already generated to perform actions ! requested by statements in the user's program. This machine code ! is organized into "modules" and is located and "linked" to the user ! program. The GNU Fortran compiler consists of several components: ! * A version of the 'gcc' command (which also might be installed as ! the system's 'cc' command) that also understands and accepts ! Fortran source code. The 'gcc' command is the "driver" program for ! all the languages in the GNU Compiler Collection (GCC); With 'gcc', you can compile the source code of any language for which a front end is available in GCC. ! * The 'gfortran' command itself, which also might be installed as the ! system's 'f95' command. 'gfortran' is just another driver program, but specifically for the Fortran compiler only. The difference ! with 'gcc' is that 'gfortran' will automatically link the correct libraries to your program. * A collection of run-time libraries. These libraries contain the ! machine code needed to support capabilities of the Fortran language ! that are not directly provided by the machine code generated by the ! 'gfortran' compilation phase, such as intrinsic functions and ! subroutines, and routines for interaction with files and the ! operating system. ! * The Fortran compiler itself, ('f951'). This is the GNU Fortran parser and code generator, linked to and interfaced with the GCC ! backend library. 'f951' "translates" the source code to assembler code. You would typically not use this program directly; instead, ! the 'gcc' or 'gfortran' driver programs will call it for you.

The free form layout was introduced in Fortran 90. Fixed form was traditionally used in older Fortran programs. When neither option is specified, the source form is determined by the file extension. ! `-fall-intrinsics' This option causes all intrinsic procedures (including the GNU-specific extensions) to be accepted. This can be useful with ! `-std=f95' to force standard-compliance but get access to the full ! range of intrinsics available with `gfortran'. As a consequence, ! `-Wintrinsics-std' will be ignored and no user-defined procedure with the same name as any intrinsic will be called except when it ! is explicitly declared `EXTERNAL'. ! `-fd-lines-as-code' ! `-fd-lines-as-comments' ! Enable special treatment for lines beginning with `d' or `D' in ! fixed form sources. If the `-fd-lines-as-code' option is given they are treated as if the first column contained a blank. If the ! `-fd-lines-as-comments' option is given, they are treated as comment lines. ! `-fdefault-double-8' ! Set the `DOUBLE PRECISION' type to an 8 byte wide type. If ! `-fdefault-real-8' is given, `DOUBLE PRECISION' would instead be ! promoted to 16 bytes if possible, and `-fdefault-double-8' can be ! used to prevent this. The kind of real constants like `1.d0' will ! not be changed by `-fdefault-real-8' though, so also ! `-fdefault-double-8' does not affect it. ! `-fdefault-integer-8' Set the default integer and logical types to an 8 byte wide type. Do nothing if this is already the default. This option also ! affects the kind of integer constants like `42'. ! `-fdefault-real-8' Set the default real type to an 8 byte wide type. Do nothing if this is already the default. This option also affects the kind of ! non-double real constants like `1.0', and does promote the default ! width of `DOUBLE PRECISION' to 16 bytes if possible, unless ! `-fdefault-double-8' is given, too. ! `-fdollar-ok' ! Allow `$' as a valid non-first character in a symbol name. Symbols ! that start with `$' are rejected since it is unclear which rules to apply to implicit typing as different vendors implement different ! rules. Using `$' in `IMPLICIT' statements is also rejected. ! `-fbackslash' Change the interpretation of backslashes in string literals from a ! single backslash character to "C-style" escape characters. The ! following combinations are expanded `\a', `\b', `\f', `\n', `\r', ! `\t', `\v', `\\', and `\0' to the ASCII characters alert, backspace, form feed, newline, carriage return, horizontal tab, vertical tab, backslash, and NUL, respectively. Additionally, ! `\x'NN, `\u'NNNN and `\U'NNNNNNNN (where each N is a hexadecimal digit) are translated into the Unicode characters corresponding to ! the specified code points. All other combinations of a character preceded by \ are unexpanded. ! `-fmodule-private' ! Set the default accessibility of module entities to `PRIVATE'. Use-associated entities will not be accessible unless they are ! explicitly declared as `PUBLIC'. ! `-ffixed-line-length-N' Set column after which characters are ignored in typical fixed-form lines in the source file, and through which spaces are assumed (as if padded to that length) after the ends of short fixed-form lines. Popular values for N include 72 (the standard and the default), 80 (card image), and 132 (corresponding to "extended-source" options ! in some popular compilers). N may also be `none', meaning that ! the entire line is meaningful and that continued character ! constants never have implicit spaces appended to them to fill out ! the line. `-ffixed-line-length-0' means the same thing as ! `-ffixed-line-length-none'. ! `-ffree-line-length-N' Set column after which characters are ignored in typical free-form ! lines in the source file. The default value is 132. N may be ! `none', meaning that the entire line is meaningful. ! `-ffree-line-length-0' means the same thing as ! `-ffree-line-length-none'. ! `-fmax-identifier-length=N' ! Specify the maximum allowed identifier length. Typical values are 31 (Fortran 95) and 63 (Fortran 2003 and Fortran 2008). ! `-fimplicit-none' Specify that no implicit typing is allowed, unless overridden by ! explicit `IMPLICIT' statements. This is the equivalent of adding ! `implicit none' to the start of every procedure. ! `-finteger-4-integer-8' ! Promote all `INTEGER(KIND=4)' entities to an `INTEGER(KIND=8)' ! entities. If `KIND=8' is unavailable, then an error will be issued. This option should be used with care and may not be suitable for your codes. Areas of possible concern include calls ! to external procedures, alignment in `EQUIVALENCE' and/or ! `COMMON', generic interfaces, BOZ literal constant conversion, and ! I/O. Inspection of the intermediate representation of the ! translated Fortran code, produced by `-fdump-tree-original', is ! suggested. ! `-fcray-pointer' Enable the Cray pointer extension, which provides C-like pointer functionality. ! `-fopenmp' ! Enable the OpenMP extensions. This includes OpenMP `!$omp' ! directives in free form and `c$omp', `*$omp' and `!$omp' ! directives in fixed form, `!$' conditional compilation sentinels ! in free form and `c$', `*$' and `!$' sentinels in fixed form, and ! when linking arranges for the OpenMP runtime library to be linked ! in. The option `-fopenmp' implies `-frecursive'. ! `-fno-range-check' Disable range checking on results of simplification of constant expressions during compilation. For example, GNU Fortran will give ! an error at compile time when simplifying `a = 1. / 0'. With this ! option, no error will be given and `a' will be assigned the value ! `+Infinity'. If an expression evaluates to a value outside of the ! relevant range of [`-HUGE()':`HUGE()'], then the expression will ! be replaced by `-Inf' or `+Inf' as appropriate. Similarly, `DATA ! i/Z'FFFFFFFF'/' will result in an integer overflow on most ! systems, but with `-fno-range-check' the value will "wrap around" ! and `i' will be initialized to -1 instead. ! `-freal-4-real-8' ! `-freal-4-real-10' ! `-freal-8-real-4' ! `-freal-8-real-10' ! `-freal-8-real-16' ! Promote all `REAL(KIND=M)' entities to `REAL(KIND=N)' entities. ! If `REAL(KIND=N)' is unavailable, then an error will be issued. ! All other real kind types are unaffected by this option. These ! options should be used with care and may not be suitable for your ! codes. Areas of possible concern include calls to external ! procedures, alignment in `EQUIVALENCE' and/or `COMMON', generic ! interfaces, BOZ literal constant conversion, and I/O. Inspection ! of the intermediate representation of the translated Fortran code, ! produced by `-fdump-tree-original', is suggested. ! `-std=STD' Specify the standard to which the program is expected to conform, ! which may be one of `f95', `f2003', `f2008', `gnu', or `legacy'. ! The default value for STD is `gnu', which specifies a superset of the Fortran 95 standard that includes all of the extensions supported by GNU Fortran, although warnings will be given for obsolete extensions not recommended for use in new code. The ! `legacy' value is equivalent but without the warnings for obsolete extensions, and may be useful for old non-standard programs. The ! `f95', `f2003' and `f2008' values specify strict conformance to ! the Fortran 95, Fortran 2003 and Fortran 2008 standards, ! respectively; errors are given for all extensions beyond the ! relevant language standard, and warnings are given for the Fortran ! 77 features that are permitted but obsolescent in later standards. ! `-std=f2008ts' allows the Fortran 2008 standard including the ! additions of the Technical Specification (TS) 29113 on Further !

'-ffree-form' ! '-ffixed-form' Specify the layout used by the source file. The free form layout was introduced in Fortran 90. Fixed form was traditionally used in older Fortran programs. When neither option is specified, the source form is determined by the file extension. ! '-fall-intrinsics' This option causes all intrinsic procedures (including the GNU-specific extensions) to be accepted. This can be useful with ! '-std=f95' to force standard-compliance but get access to the full ! range of intrinsics available with 'gfortran'. As a consequence, ! '-Wintrinsics-std' will be ignored and no user-defined procedure with the same name as any intrinsic will be called except when it ! is explicitly declared 'EXTERNAL'. ! '-fd-lines-as-code' ! '-fd-lines-as-comments' ! Enable special treatment for lines beginning with 'd' or 'D' in ! fixed form sources. If the '-fd-lines-as-code' option is given they are treated as if the first column contained a blank. If the ! '-fd-lines-as-comments' option is given, they are treated as comment lines. ! '-fdefault-double-8' ! Set the 'DOUBLE PRECISION' type to an 8 byte wide type. If ! '-fdefault-real-8' is given, 'DOUBLE PRECISION' would instead be ! promoted to 16 bytes if possible, and '-fdefault-double-8' can be ! used to prevent this. The kind of real constants like '1.d0' will ! not be changed by '-fdefault-real-8' though, so also ! '-fdefault-double-8' does not affect it. ! '-fdefault-integer-8' Set the default integer and logical types to an 8 byte wide type. Do nothing if this is already the default. This option also ! affects the kind of integer constants like '42'. ! '-fdefault-real-8' Set the default real type to an 8 byte wide type. Do nothing if this is already the default. This option also affects the kind of ! non-double real constants like '1.0', and does promote the default ! width of 'DOUBLE PRECISION' to 16 bytes if possible, unless ! '-fdefault-double-8' is given, too. ! '-fdollar-ok' ! Allow '$' as a valid non-first character in a symbol name. Symbols ! that start with '$' are rejected since it is unclear which rules to apply to implicit typing as different vendors implement different ! rules. Using '$' in 'IMPLICIT' statements is also rejected. ! '-fbackslash' Change the interpretation of backslashes in string literals from a ! single backslash character to "C-style" escape characters. The ! following combinations are expanded '\a', '\b', '\f', '\n', '\r', ! '\t', '\v', '\\', and '\0' to the ASCII characters alert, backspace, form feed, newline, carriage return, horizontal tab, vertical tab, backslash, and NUL, respectively. Additionally, ! '\x'NN, '\u'NNNN and '\U'NNNNNNNN (where each N is a hexadecimal digit) are translated into the Unicode characters corresponding to ! the specified code points. All other combinations of a character preceded by \ are unexpanded. ! '-fmodule-private' ! Set the default accessibility of module entities to 'PRIVATE'. Use-associated entities will not be accessible unless they are ! explicitly declared as 'PUBLIC'. ! '-ffixed-line-length-N' Set column after which characters are ignored in typical fixed-form lines in the source file, and through which spaces are assumed (as if padded to that length) after the ends of short fixed-form lines. Popular values for N include 72 (the standard and the default), 80 (card image), and 132 (corresponding to "extended-source" options ! in some popular compilers). N may also be 'none', meaning that the ! entire line is meaningful and that continued character constants ! never have implicit spaces appended to them to fill out the line. ! '-ffixed-line-length-0' means the same thing as ! '-ffixed-line-length-none'. ! '-ffree-line-length-N' Set column after which characters are ignored in typical free-form ! lines in the source file. The default value is 132. N may be ! 'none', meaning that the entire line is meaningful. ! '-ffree-line-length-0' means the same thing as ! '-ffree-line-length-none'. ! '-fmax-identifier-length=N' ! Specify the maximum allowed identifier length. Typical values are 31 (Fortran 95) and 63 (Fortran 2003 and Fortran 2008). ! '-fimplicit-none' Specify that no implicit typing is allowed, unless overridden by ! explicit 'IMPLICIT' statements. This is the equivalent of adding ! 'implicit none' to the start of every procedure. ! '-finteger-4-integer-8' ! Promote all 'INTEGER(KIND=4)' entities to an 'INTEGER(KIND=8)' ! entities. If 'KIND=8' is unavailable, then an error will be issued. This option should be used with care and may not be suitable for your codes. Areas of possible concern include calls ! to external procedures, alignment in 'EQUIVALENCE' and/or 'COMMON', ! generic interfaces, BOZ literal constant conversion, and I/O. ! Inspection of the intermediate representation of the translated ! Fortran code, produced by '-fdump-tree-original', is suggested. ! '-fcray-pointer' Enable the Cray pointer extension, which provides C-like pointer functionality. ! '-fopenmp' ! Enable the OpenMP extensions. This includes OpenMP '!$omp' ! directives in free form and 'c$omp', '*$omp' and '!$omp' directives ! in fixed form, '!$' conditional compilation sentinels in free form ! and 'c$', '*$' and '!$' sentinels in fixed form, and when linking ! arranges for the OpenMP runtime library to be linked in. The ! option '-fopenmp' implies '-frecursive'. ! '-fno-range-check' Disable range checking on results of simplification of constant expressions during compilation. For example, GNU Fortran will give ! an error at compile time when simplifying 'a = 1. / 0'. With this ! option, no error will be given and 'a' will be assigned the value ! '+Infinity'. If an expression evaluates to a value outside of the ! relevant range of ['-HUGE()':'HUGE()'], then the expression will be ! replaced by '-Inf' or '+Inf' as appropriate. Similarly, 'DATA ! i/Z'FFFFFFFF'/' will result in an integer overflow on most systems, ! but with '-fno-range-check' the value will "wrap around" and 'i' ! will be initialized to -1 instead. ! '-freal-4-real-8' ! '-freal-4-real-10' ! '-freal-8-real-4' ! '-freal-8-real-10' ! '-freal-8-real-16' ! Promote all 'REAL(KIND=M)' entities to 'REAL(KIND=N)' entities. If ! 'REAL(KIND=N)' is unavailable, then an error will be issued. All ! other real kind types are unaffected by this option. These options ! should be used with care and may not be suitable for your codes. ! Areas of possible concern include calls to external procedures, ! alignment in 'EQUIVALENCE' and/or 'COMMON', generic interfaces, BOZ ! literal constant conversion, and I/O. Inspection of the ! intermediate representation of the translated Fortran code, ! produced by '-fdump-tree-original', is suggested. ! '-std=STD' Specify the standard to which the program is expected to conform, ! which may be one of 'f95', 'f2003', 'f2008', 'gnu', or 'legacy'. ! The default value for STD is 'gnu', which specifies a superset of the Fortran 95 standard that includes all of the extensions supported by GNU Fortran, although warnings will be given for obsolete extensions not recommended for use in new code. The ! 'legacy' value is equivalent but without the warnings for obsolete extensions, and may be useful for old non-standard programs. The ! 'f95', 'f2003' and 'f2008' values specify strict conformance to the ! Fortran 95, Fortran 2003 and Fortran 2008 standards, respectively; ! errors are given for all extensions beyond the relevant language ! standard, and warnings are given for the Fortran 77 features that ! are permitted but obsolescent in later standards. '-std=f2008ts' ! allows the Fortran 2008 standard including the additions of the ! Technical Specification (TS) 29113 on Further Interoperability of ! Fortran with C.

Preprocessor related options. See section *note Preprocessing and ! conditional compilation:: for more detailed information on ! preprocessing in `gfortran'. ! `-cpp' ! `-nocpp' ! Enable preprocessing. The preprocessor is automatically invoked if ! the file extension is `.fpp', `.FPP', `.F', `.FOR', `.FTN', ! `.F90', `.F95', `.F03' or `.F08'. Use this option to manually ! enable preprocessing of any kind of Fortran file. To disable preprocessing of files with any of the above listed ! extensions, use the negative form: `-nocpp'. ! The preprocessor is run in traditional mode. Any restrictions of the file-format, especially the limits on line length, apply for preprocessed output as well, so it might be advisable to use the ! `-ffree-line-length-none' or `-ffixed-line-length-none' options. ! `-dM' ! Instead of the normal output, generate a list of `'#define'' directives for all the macros defined during the execution of the ! preprocessor, including predefined macros. This gives you a way of finding out what is predefined in your version of the preprocessor. ! Assuming you have no file `foo.f90', the command touch foo.f90; gfortran -cpp -E -dM foo.f90 will show all the predefined macros. ! `-dD' ! Like `-dM' except in two respects: it does not include the ! predefined macros, and it outputs both the `#define' directives ! and the result of preprocessing. Both kinds of output go to the standard output file. ! `-dN' ! Like `-dD', but emit only the macro names, not their expansions. ! `-dU' ! Like `dD' except that only macros that are expanded, or whose definedness is tested in preprocessor directives, are output; the output is delayed until the use or test of the macro; and ! `'#undef'' directives are also output for macros tested but undefined at the time. ! `-dI' ! Output `'#include'' directives in addition to the result of preprocessing. ! `-fworking-directory' Enable generation of linemarkers in the preprocessor output that will let the compiler know the current working directory at the ! time of preprocessing. When this option is enabled, the preprocessor will emit, after the initial linemarker, a second linemarker with the current working directory followed by two ! slashes. GCC will use this directory, when it is present in the ! preprocessed input, as the directory emitted as the current ! working directory in some debugging information formats. This ! option is implicitly enabled if debugging information is enabled, ! but this can be inhibited with the negated form ! `-fno-working-directory'. If the `-P' flag is present in the ! command line, this option has no effect, since no `#line' ! directives are emitted whatsoever. ! `-idirafter DIR' Search DIR for include files, but do it after all directories ! specified with `-I' and the standard system directories have been ! exhausted. DIR is treated as a system include directory. If dir ! begins with `=', then the `=' will be replaced by the sysroot ! prefix; see `--sysroot' and `-isysroot'. ! `-imultilib DIR' Use DIR as a subdirectory of the directory containing target-specific C++ headers. ! `-iprefix PREFIX' ! Specify PREFIX as the prefix for subsequent `-iwithprefix' ! options. If the PREFIX represents a directory, you should include ! the final `'/''. ! `-isysroot DIR' ! This option is like the `--sysroot' option, but applies only to ! header files. See the `--sysroot' option for more information. ! `-iquote DIR' ! Search DIR only for header files requested with `#include "file"'; ! they are not searched for `#include ', before all directories ! specified by `-I' and before the standard system directories. If ! DIR begins with `=', then the `=' will be replaced by the sysroot ! prefix; see `--sysroot' and `-isysroot'. ! `-isystem DIR' Search DIR for header files, after all directories specified by ! `-I' but before the standard system directories. Mark it as a system directory, so that it gets the same special treatment as is ! applied to the standard system directories. If DIR begins with ! `=', then the `=' will be replaced by the sysroot prefix; see ! `--sysroot' and `-isysroot'. ! `-nostdinc' Do not search the standard system directories for header files. ! Only the directories you have specified with `-I' options (and the directory of the current file, if appropriate) are searched. ! `-undef' Do not predefine any system-specific or GCC-specific macros. The standard predefined macros remain defined. ! `-APREDICATE=ANSWER' Make an assertion with the predicate PREDICATE and answer ANSWER. This form is preferred to the older form -A predicate(answer), which is still supported, because it does not use shell special characters. ! `-A-PREDICATE=ANSWER' Cancel an assertion with the predicate PREDICATE and answer ANSWER. ! `-C' ! Do not discard comments. All comments are passed through to the ! output file, except for comments in processed directives, which ! are deleted along with the directive. ! You should be prepared for side effects when using `-C'; it causes the preprocessor to treat comments as tokens in their own right. For example, comments appearing at the start of what would be a directive line have the effect of turning that line into an ordinary source line, since the first token on the line is no ! longer a `'#''. ! Warning: this currently handles C-Style comments only. The preprocessor does not yet recognize Fortran-style comments. ! `-CC' ! Do not discard comments, including during macro expansion. This is ! like `-C', except that comments contained within macros are also passed through to the output file where the macro is expanded. ! In addition to the side-effects of the `-C' option, the `-CC' ! option causes all C++-style comments inside a macro to be ! converted to C-style comments. This is to prevent later use of ! that macro from inadvertently commenting out the remainder of the ! source line. The `-CC' option is generally used to support lint ! comments. ! Warning: this currently handles C- and C++-Style comments only. The ! preprocessor does not yet recognize Fortran-style comments. ! `-DNAME' ! Predefine name as a macro, with definition `1'. ! `-DNAME=DEFINITION' The contents of DEFINITION are tokenized and processed as if they ! appeared during translation phase three in a `'#define'' directive. In particular, the definition will be truncated by embedded newline characters. --- 658,813 ---- 2.3 Enable and customize preprocessing ====================================== !

By setting the 'GFORTRAN_CONVERT_UNIT' variable, it is possible to ! change the representation of data for unformatted files. The syntax for ! the 'GFORTRAN_CONVERT_UNIT' variable is: GFORTRAN_CONVERT_UNIT: mode | mode ';' exception | exception ; mode: 'native' | 'swap' | 'big_endian' | 'little_endian' ; exception: mode ':' unit_list | unit_list ; unit_list: unit_spec | unit_list unit_spec ; unit_spec: INTEGER | INTEGER '-' INTEGER ; ! The variable consists of an optional default mode, followed by a list ! of optional exceptions, which are separated by semicolons from the preceding default and each other. Each exception consists of a format ! and a comma-separated list of units. Valid values for the modes are the ! same as for the 'CONVERT' specifier: ! 'NATIVE' Use the native format. This is the default. ! 'SWAP' Swap between little- and big-endian. ! 'LITTLE_ENDIAN' Use the little-endian format for unformatted files. ! 'BIG_ENDIAN' Use the big-endian format for unformatted files. ! A missing mode for an exception is taken to mean 'BIG_ENDIAN'. ! Examples of values for 'GFORTRAN_CONVERT_UNIT' are: ! ''big_endian'' Do all unformatted I/O in big_endian mode. ! ''little_endian;native:10-20,25'' Do all unformatted I/O in little_endian mode, except for units 10 to 20 and 25, which are in native format. ! ''10-20'' Units 10 to 20 are big-endian, the rest is native. Setting the environment variables should be done on the command line ! or via the 'export' command for 'sh'-compatible shells and via 'setenv' ! for 'csh'-compatible shells. ! Example for 'sh': $ gfortran foo.f90 $ GFORTRAN_CONVERT_UNIT='big_endian;native:10-20' ./a.out !

GNU Fortran can be used in programs with multiple threads, e.g. by using ! OpenMP, by calling OS thread handling functions via the 'ISO_C_BINDING' ! facility, or by GNU Fortran compiled library code being called from a ! multi-threaded program. ! The GNU Fortran runtime library, ('libgfortran'), supports being called concurrently from multiple threads with the following exceptions. ! During library initialization, the C 'getenv' function is used, which ! need not be thread-safe. Similarly, the 'getenv' function is used to ! implement the 'GET_ENVIRONMENT_VARIABLE' and 'GETENV' intrinsics. It is ! the responsibility of the user to ensure that the environment is not ! being updated concurrently when any of these actions are taking place. ! The 'EXECUTE_COMMAND_LINE' and 'SYSTEM' intrinsics are implemented ! with the 'system' function, which need not be thread-safe.

Then, ! using e.g. the `ISO_C_BINDING' feature, one can call the underlying ! system call to flush dirty data to stable storage, such as `fsync' on ! POSIX, `_commit' on MingW, or `fcntl(fd, F_FULLSYNC, 0)' on Mac OS X. The following example shows how to call fsync: !

Besides decimal constants, Fortran also supports binary (`b'), octal ! (`o') and hexadecimal (`z') integer constants. The syntax is: `prefix ! quote digits quote', were the prefix is either `b', `o' or `z', quote ! is either `'' or `"' and the digits are for binary `0' or `1', for ! octal between `0' and `7', and for hexadecimal between `0' and `F'. ! (Example: `b'01011101''.) Up to Fortran 95, BOZ literals were only allowed to initialize integer variables in DATA statements. Since Fortran 2003 BOZ literals ! are also allowed as argument of `REAL', `DBLE', `INT' and `CMPLX'; the result is the same as if the integer BOZ literal had been converted by ! `TRANSFER' to, respectively, `real', `double precision', `integer' or ! `complex'. As GNU Fortran extension the intrinsic procedures `FLOAT', ! `DFLOAT', `COMPLEX' and `DCMPLX' are treated alike. ! As an extension, GNU Fortran allows hexadecimal BOZ literal ! constants to be specified using the `X' prefix, in addition to the ! standard `Z' prefix. The BOZ literal can also be specified by adding a ! suffix to the string, for example, `Z'ABC'' and `'ABC'Z' are equivalent. Furthermore, GNU Fortran allows using BOZ literal constants outside DATA statements and the four intrinsic functions allowed by Fortran 2003. In DATA statements, in direct assignments, where the right-hand side only contains a BOZ literal constant, and for old-style ! initializers of the form `integer i /o'0173'/', the constant is ! transferred as if `TRANSFER' had been used; for `COMPLEX' numbers, only ! the real part is initialized unless `CMPLX' is used. In all other ! cases, the BOZ literal constant is converted to an `INTEGER' value with the largest decimal representation. This value is then converted numerically to the type and kind of the variable in question. (For ! instance, `real :: r = b'0000001' + 1' initializes `r' with `2.0'.) As different compilers implement the extension differently, one should be careful when doing bitwise initialization of non-integer variables. ! Note that initializing an `INTEGER' variable with a statement such ! as `DATA i/Z'FFFFFFFF'/' will give an integer overflow error rather ! than the desired result of -1 when `i' is a 32-bit integer on a system ! that supports 64-bit integers.

We can't simply ignore + // the closure, even though it is the last argument, because that will + // fail on targets where the function pops its arguments. So when + // generating a closure for a package-scope function we set the + // function code pointer in the closure to point to a wrapper + // function. This wrapper function accepts a final argument that + // points to the closure, ignores it, and calls the real function as a + // direct function call. This wrapper will normally be efficient, and + // can often simply be a tail call to the real function. + + // We don't use GCC's static chain pointer because 1) we don't need + // it; 2) GCC only permits using a static chain to call a known + // function, so we can't use it for an indirect call anyhow.

This + // unfortunately forces reshuffling the arguments, since there is a + // new first argument, but we can't avoid reshuffling either for + // method expressions or for indirect calls of package-scope + // functions, and since the latter are more common we reshuffle for + // method expressions. + + // Note that the Go code retains the Go types.
