Modifying GCC sources requires additional tools ++described below. ++ ++@heading Tools/packages necessary for building GCC ++@table @asis ++@item ISO C90 compiler ++Necessary to bootstrap GCC, although 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 2.95 or later) because source code for language ++frontends other than C might use GCC extensions. ++ ++@item 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. ++ ++@item A ``working'' POSIX compatible shell, or GNU bash ++ ++Necessary when running @command{configure} because some ++@command{/bin/sh} shells have bugs and may crash when configuring the ++target libraries. In other cases, @command{/bin/sh} or @command{ksh} ++have disastrous corner-case performance problems. This ++can cause target @command{configure} runs to literally take days to ++complete in some cases. ++ ++So on some platforms @command{/bin/ksh} is sufficient, on others it ++isn't. See the host/target specific instructions for your platform, or ++use @command{bash} to be sure. Then set @env{CONFIG_SHELL} in your ++environment to your ``good'' shell prior to running ++@command{configure}/@command{make}. ++ ++@command{zsh} is not a fully compliant POSIX shell and will not ++work when configuring GCC@. ++ ++@item 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. ++ ++@item GNU binutils ++ ++Necessary in some circumstances, optional in others. See the ++host/target specific instructions for your platform for the exact ++requirements. ++ ++@item gzip version 1.2.4 (or later) or ++@itemx bzip2 version 1.0.2 (or later) ++ ++Necessary to uncompress GCC @command{tar} files when source code is ++obtained via FTP mirror sites. ++ ++@item GNU make version 3.80 (or later) ++ ++You must have GNU make installed to build GCC@. ++ ++@item GNU tar version 1.14 (or later) ++ ++Necessary (only on some platforms) to untar the source code. Many ++systems' @command{tar} programs will also work, only try GNU ++@command{tar} if you have problems. ++ ++@item GNU Multiple Precision Library (GMP) version 4.1 (or later) ++ ++Necessary to build GCC@. If you do not have it installed in your ++library search path, you will have to configure with the ++@option{--with-gmp} configure option. See also @option{--with-gmp-lib} ++and @option{--with-gmp-include}. Alternatively, if a GMP source ++distribution is found in a subdirectory of your GCC sources named ++@file{gmp}, it will be built together with GCC@. ++ ++@item MPFR Library version 2.3.2 (or later) ++ ++Necessary to build GCC@. It can be downloaded from ++@uref{http://www.mpfr.org/}. The version of MPFR that is bundled with ++GMP 4.1.x contains numerous bugs. Although GCC may appear to function ++with the buggy versions of MPFR, there are a few bugs that will not be ++fixed when using this version. It is strongly recommended to upgrade ++to the recommended version of MPFR. ++ ++The @option{--with-mpfr} configure option should be used if your MPFR ++Library is not installed in your default library search path. See also ++@option{--with-mpfr-lib} and @option{--with-mpfr-include}. ++Alternatively, if a MPFR source distribution is found in a subdirectory ++of your GCC sources named @file{mpfr}, it will be built together with ++GCC@. ++ ++@item Parma Polyhedra Library (PPL) version 0.10 ++ ++Necessary to build GCC with the Graphite loop optimizations. ++It can be downloaded from @uref{http://www.cs.unipr.it/ppl/Download/}. ++ ++The @option{--with-ppl} configure option should be used if PPL is not ++installed in your default library search path. ++ ++@item CLooG-PPL version 0.15 ++ ++Necessary to build GCC with the Graphite loop optimizations. It can ++be downloaded from @uref{ftp://gcc.gnu.org/pub/gcc/infrastructure/}. ++The code in @file{cloog-ppl-0.15.tar.gz} comes from a branch of CLooG ++available from @uref{http://repo.or.cz/w/cloog-ppl.git}. CLooG-PPL ++should be configured with @option{--with-ppl}. ++ ++The @option{--with-cloog} configure option should be used if CLooG is ++not installed in your default library search path. ++ ++@item @command{jar}, or InfoZIP (@command{zip} and @command{unzip}) ++ ++Necessary to build libgcj, the GCJ runtime. ++ ++@end table ++ ++ ++@heading Tools/packages necessary for modifying GCC ++@table @asis ++@item autoconf version 2.59 ++@itemx GNU m4 version 1.4 (or later) ++ ++Necessary when modifying @file{configure.ac}, @file{aclocal.m4}, etc.@: ++to regenerate @file{configure} and @file{config.in} files. ++ ++@item automake version 1.9.6 ++ ++Necessary when modifying a @file{Makefile.am} file to regenerate its ++associated @file{Makefile.in}. ++ ++Much of GCC does not use automake, so directly edit the @file{Makefile.in} ++file. Specifically this applies to the @file{gcc}, @file{intl}, ++@file{libcpp}, @file{libiberty}, @file{libobjc} directories as well ++as any of their subdirectories. ++ ++For directories that use automake, GCC requires the latest release in ++the 1.9.x series, which is currently 1.9.6.

Each language has a tarball which includes the language ++front end as well as the language runtime (when appropriate). ++ ++Unpack the core distribution as well as any language specific ++distributions in the same directory. ++ ++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 ++(@file{bfd}, @file{binutils}, @file{gas}, @file{gprof}, @file{ld}, ++@file{opcodes}, @dots{}) to the directory containing the GCC sources. ++ ++Likewise, the GMP and MPFR libraries can be automatically built together ++with GCC. Unpack the GMP and/or MPFR source distributions in the ++directory containing the GCC sources and rename their directories to ++@file{gmp} and @file{mpfr}, respectively (or use symbolic links with the ++same name). ++ ++@html ++

Using these can lead to various sorts of build ++problems. To avoid this issue, set the @env{PWDCMD} environment ++variable to an automounter-aware @command{pwd} command, e.g., ++@command{pawd} or @samp{amq -w}, during the configuration and build ++phases. ++ ++First, we @strong{highly} recommend that GCC be built into a ++separate directory than the sources which does @strong{not} reside ++within the source tree. This is how we generally build GCC; building ++where @var{srcdir} == @var{objdir} should still work, but doesn't ++get extensive testing; building where @var{objdir} is a subdirectory ++of @var{srcdir} is unsupported. ++ ++If you have previously built GCC in the same directory for a ++different target machine, do @samp{make distclean} to delete all files ++that might be invalid. One of the files this deletes is @file{Makefile}; ++if @samp{make distclean} complains that @file{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 @var{objdir}, you should ++simply use a different @var{objdir} for each target. ++ ++Second, when configuring a native system, either @command{cc} or ++@command{gcc} must be in your path or you must set @env{CC} in ++your environment before running configure. Otherwise the configuration ++scripts may fail. ++ ++@ignore ++Note that the bootstrap compiler and the resulting GCC must be link ++compatible, else the bootstrap will fail with linker errors about ++incompatible object file formats. Several multilibed targets are ++affected by this requirement, see ++@ifnothtml ++@ref{Specific, host/target specific installation notes}. ++@end ifnothtml ++@ifhtml ++@uref{specific.html,,host/target specific installation notes}. ++@end ifhtml ++@end ignore ++ ++To configure GCC: ++ ++@smallexample ++ % mkdir @var{objdir} ++ % cd @var{objdir} ++ % @var{srcdir}/configure [@var{options}] [@var{target}] ++@end smallexample ++ ++@heading 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. ++ ++@table @code ++@item --with-pkgversion=@var{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 @command{gcc --version}. This suffix does ++not replace the default version string, only the @samp{GCC} part. ++ ++The default value is @samp{GCC}. ++ ++@item --with-bugurl=@var{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. ++ ++@end table ++ ++@heading Target specification ++@itemize @bullet ++@item ++GCC has code to correctly determine the correct value for @var{target} ++for nearly all native systems. Therefore, we highly recommend you not ++provide a configure target when configuring a native compiler. ++ ++@item ++@var{target} must be specified as @option{--target=@var{target}} ++when configuring a cross compiler; examples of valid targets would be ++m68k-coff, sh-elf, etc. ++ ++@item ++Specifying just @var{target} instead of @option{--target=@var{target}} ++implies that the host defaults to @var{target}. ++@end itemize ++ ++ ++@heading Options specification ++ ++Use @var{options} to override several configure time options for ++GCC@. A list of supported @var{options} follows; @samp{configure ++--help} may list other options, but those not listed below may not ++work and should not normally be used. ++ ++Note that each @option{--enable} option has a corresponding ++@option{--disable} option and that each @option{--with} option has a ++corresponding @option{--without} option. ++ ++@table @code ++@item --prefix=@var{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 ++@file{/usr/local}. ++ ++We @strong{highly} recommend against @var{dirname} being the same or a ++subdirectory of @var{objdir} or vice versa. If specifying a directory ++beneath a user's home directory tree, some shells will not expand ++@var{dirname} correctly if it contains the @samp{~} metacharacter; use ++@env{$HOME} instead. ++ ++The following standard @command{autoconf} options are supported. Normally you ++should not need to use these options. ++@table @code ++@item --exec-prefix=@var{dirname} ++Specify the toplevel installation directory for architecture-dependent ++files. The default is @file{@var{prefix}}. ++ ++@item --bindir=@var{dirname} ++Specify the installation directory for the executables called by users ++(such as @command{gcc} and @command{g++}). The default is ++@file{@var{exec-prefix}/bin}. ++ ++@item --libdir=@var{dirname} ++Specify the installation directory for object code libraries and ++internal data files of GCC@. The default is @file{@var{exec-prefix}/lib}. ++ ++@item --libexecdir=@var{dirname} ++Specify the installation directory for internal executables of GCC@. ++The default is @file{@var{exec-prefix}/libexec}. ++ ++@item --with-slibdir=@var{dirname} ++Specify the installation directory for the shared libgcc library. The ++default is @file{@var{libdir}}. ++ ++@item --infodir=@var{dirname} ++Specify the installation directory for documentation in info format. ++The default is @file{@var{prefix}/info}. ++ ++@item --datadir=@var{dirname} ++Specify the installation directory for some architecture-independent ++data files referenced by GCC@. The default is @file{@var{prefix}/share}. ++ ++@item --mandir=@var{dirname} ++Specify the installation directory for manual pages. The default is ++@file{@var{prefix}/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.) ++ ++@item --with-gxx-include-dir=@var{dirname} ++Specify ++the installation directory for G++ header files. The default is ++@file{@var{prefix}/include/c++/@var{version}}. ++ ++@end table ++ ++@item --program-prefix=@var{prefix} ++GCC supports some transformations of the names of its programs when ++installing them. This option prepends @var{prefix} to the names of ++programs to install in @var{bindir} (see above). For example, specifying ++@option{--program-prefix=foo-} would result in @samp{gcc} ++being installed as @file{/usr/local/bin/foo-gcc}. ++ ++@item --program-suffix=@var{suffix} ++Appends @var{suffix} to the names of programs to install in @var{bindir} ++(see above). For example, specifying @option{--program-suffix=-3.1} ++would result in @samp{gcc} being installed as ++@file{/usr/local/bin/gcc-3.1}. ++ ++@item --program-transform-name=@var{pattern} ++Applies the @samp{sed} script @var{pattern} to be applied to the names ++of programs to install in @var{bindir} (see above). @var{pattern} has to ++consist of one or more basic @samp{sed} editing commands, separated by ++semicolons. For example, if you want the @samp{gcc} program name to be ++transformed to the installed program @file{/usr/local/bin/myowngcc} and ++the @samp{g++} program name to be transformed to ++@file{/usr/local/bin/gspecial++} without changing other program names, ++you could use the pattern ++@option{--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, @var{prefix} (and ++@var{suffix}) are prepended (appended) before further transformations ++can happen with a special transformation script @var{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 ++@samp{i686-pc-linux-gnu-gcc}. All of the above transformations happen ++before the target alias is prepended to the name---so, specifying ++@option{--program-prefix=foo-} and @option{program-suffix=-3.1}, the ++resulting binary would be installed as ++@file{/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. ++ ++@item --with-local-prefix=@var{dirname} ++Specify the ++installation directory for local include files. The default is ++@file{/usr/local}. Specify this option if you want the compiler to ++search directory @file{@var{dirname}/include} for locally installed ++header files @emph{instead} of @file{/usr/local/include}. ++ ++You should specify @option{--with-local-prefix} @strong{only} if your ++site has a different convention (not @file{/usr/local}) for where to put ++site-specific files. ++ ++The default value for @option{--with-local-prefix} is @file{/usr/local} ++regardless of the value of @option{--prefix}. Specifying ++@option{--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 @option{--prefix} is to specify where to @emph{install ++GCC}. The local header files in @file{/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 @option{--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 @option{-I @var{directory}} options to the ++compiler command line, to ensure that directories containing installed ++packages' headers are searched. When @var{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 ++@env{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 @file{/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 ++@option{--program-prefix}, @option{--program-suffix} and ++@option{--program-transform-name} options to install multiple versions ++into a single directory, but it may be simpler to use different prefixes ++and the @option{--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 @env{LIBRARY_PATH}). ++ ++The same value can be used for both @option{--with-local-prefix} and ++@option{--prefix} provided it is not @file{/usr}. This can be used ++to avoid the default search of @file{/usr/local/include}. ++ ++@strong{Do not} specify @file{/usr} as the @option{--with-local-prefix}! ++The directory you use for @option{--with-local-prefix} @strong{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 @command{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. ++ ++@item --enable-shared[=@var{package}[,@dots{}]] ++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 ++@samp{libgcc} (also known as @samp{gcc}), @samp{libstdc++} (not ++@samp{libstdc++-v3}), @samp{libffi}, @samp{zlib}, @samp{boehm-gc}, ++@samp{ada}, @samp{libada}, @samp{libjava} and @samp{libobjc}. ++Note @samp{libiberty} does not support shared libraries at all. ++ ++Use @option{--disable-shared} to build only static libraries. Note that ++@option{--disable-shared} does not accept a list of package names as ++argument, only @option{--enable-shared} does. ++ ++@item @anchor{with-gnu-as}--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 @option{--with-gnu-as}.) If you have more than one ++assembler installed on your system, you may want to use this option in ++connection with @option{--with-as=@var{pathname}} or ++@option{--with-build-time-tools=@var{pathname}}. ++ ++The following systems are the only ones where it makes a difference ++whether you use the GNU assembler. On any other system, ++@option{--with-gnu-as} has no effect. ++ ++@itemize @bullet ++@item @samp{hppa1.0-@var{any}-@var{any}} ++@item @samp{hppa1.1-@var{any}-@var{any}} ++@item @samp{sparc-sun-solaris2.@var{any}} ++@item @samp{sparc64-@var{any}-solaris2.@var{any}} ++@end itemize ++ ++@item @anchor{with-as}--with-as=@var{pathname} ++Specify that the compiler should use the assembler pointed to by ++@var{pathname}, rather than the one found by the standard rules to find ++an assembler, which are: ++@itemize @bullet ++@item ++Unless GCC is being built with a cross compiler, check the ++@file{@var{libexec}/gcc/@var{target}/@var{version}} directory. ++@var{libexec} defaults to @file{@var{exec-prefix}/libexec}; ++@var{exec-prefix} defaults to @var{prefix}, which ++defaults to @file{/usr/local} unless overridden by the ++@option{--prefix=@var{pathname}} switch described above. @var{target} ++is the target system triple, such as @samp{sparc-sun-solaris2.7}, and ++@var{version} denotes the GCC version, such as 3.0. ++ ++@item ++If the target system is the same that you are building on, check ++operating system specific directories (e.g.@: @file{/usr/ccs/bin} on ++Sun Solaris 2). ++ ++@item ++Check in the @env{PATH} for a tool whose name is prefixed by the ++target system triple. ++ ++@item ++Check in the @env{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). ++@end itemize ++ ++You may want to use @option{--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. ++ ++@item @anchor{with-gnu-ld}--with-gnu-ld ++Same as @uref{#with-gnu-as,,@option{--with-gnu-as}} ++but for the linker. ++ ++@item --with-ld=@var{pathname} ++Same as @uref{#with-as,,@option{--with-as}} ++but for the linker. ++ ++@item --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 @option{--with-stabs} when you configure GCC@. ++ ++No matter which default you choose when you configure GCC, the user ++can use the @option{-gcoff} and @option{-gstabs+} options to specify explicitly ++the debug format for a particular compilation. ++ ++@option{--with-stabs} is meaningful on the ISC system on the 386, also, if ++@option{--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. ++ ++@option{--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. ++ ++@item --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., @option{--disable-softfloat}): ++@table @code ++@item arc-*-elf* ++biendian. ++ ++@item arm-*-* ++fpu, 26bit, underscore, interwork, biendian, nofmult. ++ ++@item m68*-*-* ++softfloat, m68881, m68000, m68020. ++ ++@item mips*-*-* ++single-float, biendian, softfloat. ++ ++@item powerpc*-*-*, rs6000*-*-* ++aix64, pthread, softfloat, powercpu, powerpccpu, powerpcos, biendian, ++sysv, aix. ++ ++@end table ++ ++@item --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, @option{--enable-threads} is an ++alias for @option{--enable-threads=single}. ++ ++@item --disable-threads ++Specify that threading support should be disabled for the system. ++This is an alias for @option{--enable-threads=single}. ++ ++@item --enable-threads=@var{lib} ++Specify that ++@var{lib} is the thread support library.

As with ++@option{--with-cpu}, which switches will be accepted and acceptable values ++of the arguments depend on the target. ++ ++@item --with-mode=@var{mode} ++Specify if the compiler should default to @option{-marm} or @option{-mthumb}. ++This option is only supported on ARM targets. ++ ++@item --with-divide=@var{type} ++Specify how the compiler should generate code for checking for ++division by zero.

This option is currently ++only available on systems with GNU libc. When enabled, this will cause ++@option{-fuse-cxa-atexit} to be passed by default. ++ ++@item --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. ++ ++@item --disable-cpp ++Specify that a user visible @command{cpp} program should not be installed. ++ ++@item --with-cpp-install-dir=@var{dirname} ++Specify that the user visible @command{cpp} program should be installed ++in @file{@var{prefix}/@var{dirname}/cpp}, in addition to @var{bindir}. ++ ++@item --enable-initfini-array ++Force the use of sections @code{.init_array} and @code{.fini_array} ++(instead of @code{.init} and @code{.fini}) for constructors and ++destructors.

The list of valid values is the same as for ++@option{--enable-languages}, and the option @code{all} will select all ++of the languages enabled by @option{--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 @command{make ++stage1-bubble all-target}, or run the testsuite on the stage-1 compiler ++for the specified languages using @command{make stage1-start check-gcc}. ++ ++@item --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 @samp{make -C gcc gnatlib_and_tools}. ++ ++@item --disable-libssp ++Specify that the run-time libraries for stack smashing protection ++should not be built. ++ ++@item --disable-libgomp ++Specify that the run-time libraries used by GOMP should not be built. ++ ++@item --with-dwarf2 ++Specify that the compiler should ++use DWARF 2 debugging information as the default. ++ ++@item --enable-targets=all ++@itemx --enable-targets=@var{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.

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. ++Currently, this option only affects sparc-linux, powerpc-linux and ++x86-linux. ++ ++@item --enable-secureplt ++This option enables @option{-msecure-plt} by default for powerpc-linux. ++@ifnothtml ++@xref{RS/6000 and PowerPC Options,, RS/6000 and PowerPC Options, gcc, ++Using the GNU Compiler Collection (GCC)}, ++@end ifnothtml ++@ifhtml ++See ``RS/6000 and PowerPC Options'' in the main manual ++@end ifhtml ++ ++@item --enable-cld ++This option enables @option{-mcld} by default for 32-bit x86 targets. ++@ifnothtml ++@xref{i386 and x86-64 Options,, i386 and x86-64 Options, gcc, ++Using the GNU Compiler Collection (GCC)}, ++@end ifnothtml ++@ifhtml ++See ``i386 and x86-64 Options'' in the main manual ++@end ifhtml ++ ++@item --enable-win32-registry ++@itemx --enable-win32-registry=@var{key} ++@itemx --disable-win32-registry ++The @option{--enable-win32-registry} option enables Microsoft Windows-hosted GCC ++to look up installations paths in the registry using the following key: ++ ++@smallexample ++@code{HKEY_LOCAL_MACHINE\SOFTWARE\Free Software Foundation\@var{key}} ++@end smallexample ++ ++@var{key} defaults to GCC version number, and can be overridden by the ++@option{--enable-win32-registry=@var{key}} option.

This feature is enabled ++by default, and can be disabled by @option{--disable-win32-registry} ++option. This option has no effect on the other hosts. ++ ++@item --nfp ++Specify that the machine does not have a floating point unit. This ++option only applies to @samp{m68k-sun-sunos@var{n}}.

However it defaults to off for release branches and ++final releases. The specific files which get @option{-Werror} are ++controlled by the Makefiles. ++ ++@item --enable-checking ++@itemx --enable-checking=@var{list} ++When you specify this option, the compiler is built to perform internal ++consistency checks of the requested complexity.

This is @samp{yes} by default when building ++from SVN or snapshots, but @samp{release} for releases. The default ++for building the stage1 compiler is @samp{yes}. More control ++over the checks may be had by specifying @var{list}. The categories of ++checks available are @samp{yes} (most common checks ++@samp{assert,misc,tree,gc,rtlflag,runtime}), @samp{no} (no checks at ++all), @samp{all} (all but @samp{valgrind}), @samp{release} (cheapest ++checks @samp{assert,runtime}) or @samp{none} (same as @samp{no}). ++Individual checks can be enabled with these flags @samp{assert}, ++@samp{df}, @samp{fold}, @samp{gc}, @samp{gcac} @samp{misc}, @samp{rtl}, ++@samp{rtlflag}, @samp{runtime}, @samp{tree}, and @samp{valgrind}. ++ ++The @samp{valgrind} check requires the external @command{valgrind} ++simulator, available from @uref{http://valgrind.org/}. The ++@samp{df}, @samp{rtl}, @samp{gcac} and @samp{valgrind} checks are very expensive. ++To disable all checking, @samp{--disable-checking} or ++@samp{--enable-checking=none} must be explicitly requested.

To build the stage1 compiler with ++different checking options use @option{--enable-stage1-checking}. ++The list of checking options is the same as for @option{--enable-checking}. ++If your system is too slow or too small to bootstrap a released compiler ++with checking for stage1 enabled, you can use @samp{--disable-stage1-checking} ++to disable checking for the stage1 compiler. ++ ++@item --enable-coverage ++@itemx --enable-coverage=@var{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 ++@var{level} argument controls whether the compiler is built optimized or ++not, values are @samp{opt} and @samp{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. ++ ++@item --enable-gather-detailed-mem-stats ++When this option is specified more detailed information on memory ++allocation is gathered.

You can ++optionally control which decimal floating point format is used (either ++@samp{bid} or @samp{dpd}). The @samp{bid} (binary integer decimal) ++format is default on i386 and x86_64 systems, and the @samp{dpd} ++(densely packed decimal) format is default on PowerPC systems. ++ ++@item --enable-fixed-point ++@itemx --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.

This option is ++only useful when you are already using @option{--with-sysroot}. You ++can use @option{--with-build-sysroot} when you are configuring with ++@option{--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. ++ ++@item --with-headers ++@itemx --with-headers=@var{dir} ++Deprecated in favor of @option{--with-sysroot}. ++Specifies that target headers are available when building a cross compiler. ++The @var{dir} argument specifies a directory which has the target include ++files.

These libraries will be copied into the @file{gcc} install ++directory. If the directory list is omitted, this option has no ++effect. ++ ++@item --with-newlib ++Specifies that @samp{newlib} is ++being used as the target C library.

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 @samp{libgcj} isn't built, you ++may need to port it; in this case, before modifying the top-level ++@file{configure.in} so that @samp{libgcj} is enabled by default on this platform, ++you may use @option{--enable-libgcj} to override the default. ++ ++@end table ++ ++The following options apply to building @samp{libgcj}. ++ ++@subsubheading General Options ++ ++@table @code ++@item --enable-java-maintainer-mode ++By default the @samp{libjava} build will not attempt to compile the ++@file{.java} source files to @file{.class}. Instead, it will use the ++@file{.class} files from the source tree. If you use this option you ++must have executables named @command{ecj1} and @command{gjavah} in your path ++for use by the build. You must use this option if you intend to ++modify any @file{.java} files in @file{libjava}. ++ ++@item --with-java-home=@var{dirname} ++This @samp{libjava} option overrides the default value of the ++@samp{java.home} system property. It is also used to set ++@samp{sun.boot.class.path} to @file{@var{dirname}/lib/rt.jar}. By ++default @samp{java.home} is set to @file{@var{prefix}} and ++@samp{sun.boot.class.path} to ++@file{@var{datadir}/java/libgcj-@var{version}.jar}. ++ ++@item --with-ecj-jar=@var{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 @command{gcj} to parse ++@file{.java} source files. If this option is given, the ++@samp{libjava} build will create and install an @file{ecj1} executable ++which uses this jar file at runtime. ++ ++If this option is not given, but an @file{ecj.jar} file is found in ++the topmost source tree at configure time, then the @samp{libgcj} ++build will create and install @file{ecj1}, and will also install the ++discovered @file{ecj.jar} into a suitable place in the install tree. ++ ++If @file{ecj1} is not installed, then the user will have to supply one ++on his path in order for @command{gcj} to properly parse @file{.java} ++source files. A suitable jar is available from ++@uref{ftp://sourceware.org/pub/java/}. ++ ++@item --disable-getenv-properties ++Don't set system properties from @env{GCJ_PROPERTIES}. ++ ++@item --enable-hash-synchronization ++Use a global hash table for monitor locks. Ordinarily, ++@samp{libgcj}'s @samp{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. ++ ++@item --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 @option{--disable-interpreter}). ++ ++@item --disable-java-net ++Disable java.net. This disables the native part of java.net only, ++using non-functional stubs for native method implementations. ++ ++@item --disable-jvmpi ++Disable JVMPI support. ++ ++@item --disable-libgcj-bc ++Disable BC ABI compilation of certain parts of libgcj. By default, ++some portions of libgcj are compiled with @option{-findirect-dispatch} ++and @option{-fno-indirect-classes}, allowing them to be overridden at ++run-time. ++ ++If @option{--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. ++ ++@item --enable-reduced-reflection ++Build most of libgcj with @option{-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). ++ ++@item --with-ecos ++Enable runtime eCos target support. ++ ++@item --without-libffi ++Don't use @samp{libffi}. This will disable the interpreter and JNI ++support as well, as these require @samp{libffi} to work. ++ ++@item --enable-libgcj-debug ++Enable runtime debugging code. ++ ++@item --enable-libgcj-multifile ++If specified, causes all @file{.java} source files to be ++compiled into @file{.class} files in one invocation of ++@samp{gcj}. This can speed up build time, but is more ++resource-intensive.

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 @command{fixincludes} if the ++System V file system doesn't support symbolic links. These problems ++result in a failure to fix the declaration of @code{size_t} in ++@file{sys/types.h}. If you find that @code{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 ++@file{*.l} files, you need the Flex lexical analyzer generator ++installed. If you do not modify @file{*.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. ++ ++@section Building a native compiler ++ ++For a native build, the default configuration is to perform ++a 3-stage bootstrap of the compiler when @samp{make} is invoked. ++This will build the entire GCC system and ensure that it compiles ++itself correctly. It can be disabled with the @option{--disable-bootstrap} ++parameter to @samp{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: ++ ++@itemize @bullet ++@item ++Build tools necessary to build the compiler. ++ ++@item ++Perform a 3-stage bootstrap of the compiler. This includes building ++three times the target tools for use by the compiler such as binutils ++(bfd, binutils, gas, gprof, ld, and opcodes) if they have been ++individually linked or moved into the top level GCC source tree before ++configuring. ++ ++@item ++Perform a comparison test of the stage2 and stage3 compilers. ++ ++@item ++Build runtime libraries using the stage3 compiler from the previous step. ++ ++@end itemize ++ ++If you are short on disk space you might consider @samp{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 @code{BOOT_CFLAGS} on the command line when ++doing @samp{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.) ++ ++@smallexample ++ make BOOT_CFLAGS='-O' bootstrap ++@end smallexample ++ ++You can place non-default optimization flags into @code{BOOT_CFLAGS}; they ++are less well tested here than the default of @samp{-g -O2}, but should ++still work. In a few cases, you may find that you need to specify special ++flags such as @option{-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 @code{BOOT_CFLAGS} to avoid the parts ++of the stage1 compiler that were miscompiled, or by using @samp{make ++bootstrap4} to increase the number of stages of bootstrap. ++ ++@code{BOOT_CFLAGS} does not apply to bootstrapped target libraries. ++Since these are always compiled with the compiler currently being ++bootstrapped, you can use @code{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 @code{STAGE1_LIBCFLAGS} to this end. ++ ++If you used the flag @option{--enable-languages=@dots{}} 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 @env{LANGUAGES} when calling @samp{make} ++@strong{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 @file{Makefile}.) ++ ++If you do not want to bootstrap your compiler, you can configure with ++@option{--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 ++@code{powerpc-unknown-linux-gnu} toolchain on a ++@code{powerpc64-unknown-linux-gnu} host. In this case, pass ++@option{--enable-bootstrap} to the configure script. ++ ++ ++@section 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 first recommend 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 ++@option{--with-ecj-jar=@dots{}}. ++ ++Assuming you have already installed a native copy of GCC and configured ++your cross compiler, issue the command @command{make}, which performs the ++following steps: ++ ++@itemize @bullet ++@item ++Build host tools necessary to build the compiler. ++ ++@item ++Build target tools for use by the compiler such as binutils (bfd, ++binutils, gas, gprof, ld, and opcodes) ++if they have been individually linked or moved into the top level GCC source ++tree before configuring. ++ ++@item ++Build the compiler (single stage only). ++ ++@item ++Build runtime libraries using the compiler from the previous step. ++@end itemize ++ ++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 ++@file{@var{prefix}/@var{target}/bin}. Here is a table of the tools ++you should put in this directory: ++ ++@table @file ++@item as ++This should be the cross-assembler. ++ ++@item ld ++This should be the cross-linker. ++ ++@item ar ++This should be the cross-archiver: a program which can manipulate ++archive files (linker libraries) in the target machine's format. ++ ++@item ranlib ++This should be a program to construct a symbol table in an archive file. ++@end table ++ ++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 @option{--host} and @option{--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 ++@option{--with-sysroot} or @option{--with-headers} and ++@option{--with-libs}. Many targets also require ``start files'' such ++as @file{crt0.o} and ++@file{crtn.o} which are linked into each executable. There may be several ++alternatives for @file{crt0.o}, for use with profiling or other ++compilation options. Check your target's definition of ++@code{STARTFILE_SPEC} to find out what start files it uses. ++ ++@section Building in parallel ++ ++GNU Make 3.79 and above, which is necessary to build GCC, support ++building in parallel. To activate this, you can use @samp{make -j 2} ++instead of @samp{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. ++ ++@section Building the Ada compiler ++ ++In order to build GNAT, the Ada compiler, you need a working GNAT ++compiler (GCC version 3.4 or later). ++This includes GNAT tools such as @command{gnatmake} and ++@command{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. ++ ++@command{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 @option{--enable-languages} is ++used to disable building the Ada front end. ++ ++@env{ADA_INCLUDE_PATH} and @env{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 @samp{gnatls -v} lists only one explicit path in each ++section. ++ ++@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 @code{make profiledbootstrap}. ++ ++When @samp{make profiledbootstrap} is run, it will first build a @code{stage1} ++compiler. This compiler is used to build a @code{stageprofile} compiler ++instrumented to collect execution counts of instruction and branch ++probabilities. Then runtime libraries are compiled with profile collected. ++Finally a @code{stagefeedback} compiler is built using the information collected. ++ ++Unlike standard bootstrap, several additional restrictions apply. The ++compiler used to build @code{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. ++ ++@html ++

This includes ++@uref{http://www.gnu.org/software/dejagnu/,,DejaGnu}, Tcl, and Expect; ++the DejaGnu site has links to these. ++ ++If the directories where @command{runtest} and @command{expect} were ++installed are not in the @env{PATH}, you may need to set the following ++environment variables appropriately, as in the following example (which ++assumes that DejaGnu has been installed under @file{/usr/local}): ++ ++@smallexample ++ TCL_LIBRARY = /usr/local/share/tcl8.0 ++ DEJAGNULIBS = /usr/local/share/dejagnu ++@end smallexample ++ ++(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): ++@smallexample ++ cd @var{objdir}; make -k check ++@end smallexample ++ ++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 ++@samp{WARNING: Couldn't find the global config file.} or ++@samp{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 @uref{http://gcc.gnu.org/simtest-howto.html}. ++ ++@section How can you run the testsuite on selected tests? ++ ++In order to run sets of tests selectively, there are targets ++@samp{make check-gcc} and @samp{make check-g++} ++in the @file{gcc} subdirectory of the object directory. You can also ++just run @samp{make check} in a subdirectory of the object directory. ++ ++ ++A more selective way to just run all @command{gcc} execute tests in the ++testsuite is to use ++ ++@smallexample ++ make check-gcc RUNTESTFLAGS="execute.exp @var{other-options}" ++@end smallexample ++ ++Likewise, in order to run only the @command{g++} ``old-deja'' tests in ++the testsuite with filenames matching @samp{9805*}, you would use ++ ++@smallexample ++ make check-g++ RUNTESTFLAGS="old-deja.exp=9805* @var{other-options}" ++@end smallexample ++ ++The @file{*.exp} files are located in the testsuite directories of the GCC ++source, the most important ones being @file{compile.exp}, ++@file{execute.exp}, @file{dg.exp} and @file{old-deja.exp}. ++To get a list of the possible @file{*.exp} files, pipe the ++output of @samp{make check} into a file and look at the ++@samp{Running @dots{} .exp} lines. ++ ++@section Passing options and running multiple testsuites ++ ++You can pass multiple options to the testsuite using the ++@samp{--target_board} option of DejaGNU, either passed as part of ++@samp{RUNTESTFLAGS}, or directly to @command{runtest} if you prefer to ++work outside the makefiles. For example, ++ ++@smallexample ++ make check-g++ RUNTESTFLAGS="--target_board=unix/-O3/-fmerge-constants" ++@end smallexample ++ ++will run the standard @command{g++} testsuites (``unix'' is the target name ++for a standard native testsuite situation), passing ++@samp{-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: ++ ++@smallexample ++ @dots{}"--target_board=arm-sim\@{-mhard-float,-msoft-float\@}\@{-O1,-O2,-O3,\@}" ++@end smallexample ++ ++(Note the empty option caused by the trailing comma in the final group.) ++The following will run each testsuite eight times using the @samp{arm-sim} ++target, as if you had specified all possible combinations yourself: ++ ++@smallexample ++ --target_board=arm-sim/-mhard-float/-O1 ++ --target_board=arm-sim/-mhard-float/-O2 ++ --target_board=arm-sim/-mhard-float/-O3 ++ --target_board=arm-sim/-mhard-float ++ --target_board=arm-sim/-msoft-float/-O1 ++ --target_board=arm-sim/-msoft-float/-O2 ++ --target_board=arm-sim/-msoft-float/-O3 ++ --target_board=arm-sim/-msoft-float ++@end smallexample ++ ++They can be combined as many times as you wish, in arbitrary ways. This ++list: ++ ++@smallexample ++ @dots{}"--target_board=unix/-Wextra\@{-O3,-fno-strength\@}\@{-fomit-frame,\@}" ++@end smallexample ++ ++will generate four combinations, all involving @samp{-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 @command{make} ++do the parallel runs. Instead of using @samp{--target_board}, use a ++special makefile target: ++ ++@smallexample ++ make -j@var{N} check-@var{testsuite}//@var{test-target}/@var{option1}/@var{option2}/@dots{} ++@end smallexample ++ ++For example, ++ ++@smallexample ++ make -j3 check-gcc//sh-hms-sim/@{-m1,-m2,-m3,-m3e,-m4@}/@{,-nofpu@} ++@end smallexample ++ ++will run three concurrent ``make-gcc'' testsuites, eventually testing all ++ten combinations as described above. Note that this is currently only ++supported in the @file{gcc} subdirectory. (To see how this works, try ++typing @command{echo} before the example given here.) ++ ++ ++@section Additional testing for Java Class Libraries ++ ++The Java runtime tests can be executed via @samp{make check} ++in the @file{@var{target}/libjava/testsuite} directory in ++the build tree. ++ ++The @uref{http://sourceware.org/mauve/,,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 @file{libjava/testsuite/libjava.mauve/mauve}, or by ++specifying the location of that tree when invoking @samp{make}, as in ++@samp{make MAUVEDIR=~/mauve check}. ++ ++@section How to interpret test results ++ ++The result of running the testsuite are various @file{*.sum} and @file{*.log} ++files in the testsuite subdirectories. The @file{*.log} files contain a ++detailed log of the compiler invocations and the corresponding ++results, the @file{*.sum} files summarize the results. These summaries ++contain status codes for all tests: ++ ++@itemize @bullet ++@item ++PASS: the test passed as expected ++@item ++XPASS: the test unexpectedly passed ++@item ++FAIL: the test unexpectedly failed ++@item ++XFAIL: the test failed as expected ++@item ++UNSUPPORTED: the test is not supported on this platform ++@item ++ERROR: the testsuite detected an error ++@item ++WARNING: the testsuite detected a possible problem ++@end itemize ++ ++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. ++ ++ ++@section Submitting test results ++ ++If you want to report the results to the GCC project, use the ++@file{contrib/test_summary} shell script. Start it in the @var{objdir} with ++ ++@smallexample ++ @var{srcdir}/contrib/test_summary -p your_commentary.txt \ ++ -m gcc-testresults@@gcc.gnu.org |sh ++@end smallexample ++ ++This script uses the @command{Mail} program to send the results, so ++make sure it is in your @env{PATH}. The file @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. ++ ++@html ++

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 @file{@var{prefix}/bin} where @var{prefix} is the value ++you specified with the @option{--prefix} to configure (or ++@file{/usr/local} by default). (If you specified @option{--bindir}, ++that directory will be used instead; otherwise, if you specified ++@option{--exec-prefix}, @file{@var{exec-prefix}/bin} will be used.) ++Headers for the C++ and Java libraries are installed in ++@file{@var{prefix}/include}; libraries in @file{@var{libdir}} ++(normally @file{@var{prefix}/lib}); internal parts of the compiler in ++@file{@var{libdir}/gcc} and @file{@var{libexecdir}/gcc}; documentation ++in info format in @file{@var{infodir}} (normally ++@file{@var{prefix}/info}). ++ ++When installing cross-compilers, GCC's executables ++are not only installed into @file{@var{bindir}}, that ++is, @file{@var{exec-prefix}/bin}, but additionally into ++@file{@var{exec-prefix}/@var{target-alias}/bin}, if that directory ++exists. Typically, such @dfn{tooldirs} hold target-specific ++binutils, including assembler and linker. ++ ++Installation into a temporary staging area or into a @command{chroot} ++jail can be achieved with the command ++ ++@smallexample ++make DESTDIR=@var{path-to-rootdir} install ++@end smallexample ++ ++@noindent where @var{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 @code{DESTDIR} ++need not exist yet; it will be created if necessary. ++ ++There is a subtle point with tooldirs and @code{DESTDIR}: ++If you relocate a cross-compiler installation with ++e.g.@: @samp{DESTDIR=@var{rootdir}}, then the directory ++@file{@var{rootdir}/@var{exec-prefix}/@var{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 @code{DESTDIR} feature. ++ ++If you are bootstrapping a released version of GCC then please ++quickly review the build status page for your release, available from ++@uref{http://gcc.gnu.org/buildstat.html}. ++If your system is not listed for the version of GCC that you built, ++send a note to ++@email{gcc@@gcc.gnu.org} indicating ++that you successfully built and installed GCC@. ++Include the following information: ++ ++@itemize @bullet ++@item ++Output from running @file{@var{srcdir}/config.guess}.

(These are the versions which identify themselves as DEC ++OSF/1.) ++ ++In Digital Unix V4.0, virtual memory exhausted bootstrap failures ++may be fixed by configuring with @option{--with-gc=simple}, ++reconfiguring Kernel Virtual Memory and Swap parameters ++per the @command{/usr/sbin/sys_check} Tuning Suggestions, ++or applying the patch in ++@uref{http://gcc.gnu.org/ml/gcc/2002-08/msg00822.html}. ++ ++In Tru64 UNIX V5.1, Compaq introduced a new assembler that does not ++currently (2001-06-13) work with @command{mips-tfile}. As a workaround, ++we need to use the old assembler, invoked via the barely documented ++@option{-oldas} option. To bootstrap GCC, you either need to use the ++Compaq C Compiler: ++ ++@smallexample ++ % CC=cc @var{srcdir}/configure [@var{options}] [@var{target}] ++@end smallexample ++ ++or you can use a copy of GCC 2.95.3 or higher built on Tru64 UNIX V4.0: ++ ++@smallexample ++ % CC=gcc -Wa,-oldas @var{srcdir}/configure [@var{options}] [@var{target}] ++@end smallexample ++ ++As of GNU binutils 2.11.2, neither GNU @command{as} nor GNU @command{ld} ++are supported on Tru64 UNIX, so you must not configure GCC with ++@option{--with-gnu-as} or @option{--with-gnu-ld}. ++ ++GCC writes a @samp{.verstamp} directive to the assembler output file ++unless it is built as a cross-compiler. It gets the version to use from ++the system header file @file{/usr/include/stamp.h}. If you install a ++new version of DEC Unix, you should rebuild GCC to pick up the new version ++stamp. ++ ++@samp{make compare} may fail on old versions of DEC Unix unless you add ++@option{-save-temps} to @code{BOOT_CFLAGS}. On these systems, the name ++of the assembler input file is stored in the object file, and that makes ++comparison fail if it differs between the @code{stage1} and ++@code{stage2} compilations. The option @option{-save-temps} forces a ++fixed name to be used for the assembler input file, instead of a ++randomly chosen name in @file{/tmp}. Do not add @option{-save-temps} ++unless the comparisons fail without that option. If you add ++@option{-save-temps}, you will have to manually delete the @samp{.i} and ++@samp{.s} files after each series of compilations. ++ ++GCC now supports both the native (ECOFF) debugging format used by DBX ++and GDB and an encapsulated STABS format for use only with GDB@. See the ++discussion of the @option{--with-stabs} option of @file{configure} above ++for more information on these formats and how to select them. ++ ++There is a bug in DEC's assembler that produces incorrect line numbers ++for ECOFF format when the @samp{.align} directive is used. To work ++around this problem, GCC will not emit such alignment directives ++while writing ECOFF format debugging information even if optimization is ++being performed. Unfortunately, this has the very undesirable ++side-effect that code addresses when @option{-O} is specified are ++different depending on whether or not @option{-g} is also specified. ++ ++To avoid this behavior, specify @option{-gstabs+} and use GDB instead of ++DBX@. DEC is now aware of this problem with the assembler and hopes to ++provide a fix shortly. ++ ++@html ++

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, @option{-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 ++@samp{make all-host all-target} after getting the failure from @samp{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 @samp{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.

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 @uref{binaries.html,,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 ++@option{--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 @samp{hppa[1-2]*-hp-hpux11*} target generates code ++for the 32-bit PA-RISC runtime architecture and uses the HP linker. ++The @samp{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 @env{PATH} or @env{CC} so ++that configure finds an appropriate compiler for the initial bootstrap. ++When @env{CC} is used, the definition should contain the options that are ++needed whenever @env{CC} is used. ++ ++Specifically, options that determine the runtime architecture must be ++in @env{CC} to correctly select the target for the build. It is also ++convenient to place many other compiler options in @env{CC}. For example, ++@env{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 @option{+DA2.0W} option will result in ++the automatic selection of the @samp{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 ++@option{-Ac} option. These defines aren't necessary with @option{-Ae}. ++ ++It is best to explicitly configure the @samp{hppa64-hp-hpux11*} target ++with the @option{--with-ld=@dots{}} 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. @code{PHSS_26559} and @code{PHSS_24304} are the ++oldest linker patches that are known to work. They are for HP-UX ++11.00 and 11.11, respectively. @code{PHSS_24303}, the companion to ++@code{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 @option{+init} and @option{+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 ++@samp{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 @option{-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 @option{--disable-symvers} when using GNU ld. ++ ++POSIX threads are the default. The optional DCE thread library is not ++supported, so @option{--enable-threads=dce} does not work. ++ ++@html ++

Building GMP and MPFR ++as static archive libraries works better than shared libraries. ++ ++Errors involving @code{alloca} when building GCC generally are due ++to an incorrect definition of @code{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 @strong{must} be invoked as @command{cc} ++(not @command{xlc}). Once @command{configure} has been informed of ++@command{xlc}, one needs to use @samp{make distclean} to remove the ++configure cache files and ensure that @env{CC} environment variable ++does not provide a definition that will confuse @command{configure}. ++If this error occurs during stage2 or later, then the problem most likely ++is the version of Make (see above). ++ ++The native @command{as} and @command{ld} are recommended for bootstrapping ++on AIX 4 and required for bootstrapping on AIX 5L@.

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 ++a 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 ++@command{groff} 1.19.1 without getting messages similar to the following: ++ ++@smallexample ++ld: warning: relocation error: R_SPARC_UA32: @dots{} ++ external symbolic relocation against non-allocatable section ++ .debug_info cannot be processed at runtime: relocation ignored. ++@end smallexample ++ ++To work around this problem, compile with @option{-gstabs+} instead of ++plain @option{-g}. ++ ++When configuring the GNU Multiple Precision Library (GMP) or the MPFR ++library on a Solaris 7 or later system, the canonical target triplet ++must be specified as the @command{build} parameter on the configure ++line. This triplet can be obtained by invoking ./config.guess in ++the toplevel source directory of GCC (and not that of GMP or MPFR). ++For example on a Solaris 7 system: ++ ++@smallexample ++ % ./configure --build=sparc-sun-solaris2.7 --prefix=xxx ++@end smallexample ++ ++@html ++

This problem (Sun bug 4210064) affects GCC 2.8 ++and later, including all EGCS releases. Sun formerly recommended ++107058-01 for all Solaris 7 users, but around 1999-09-01 it started to ++recommend it only for people who use Sun's compilers. ++ ++Here are some workarounds to this problem: ++@itemize @bullet ++@item ++Do not install Sun patch 107058-01 until after Sun releases a ++complete patch for bug 4210064. This is the simplest course to take, ++unless you must also use Sun's C compiler. Unfortunately 107058-01 ++is preinstalled on some new Solaris 7-based hosts, so you may have to ++back it out. ++ ++@item ++Copy the original, unpatched Solaris 7 ++@command{/usr/ccs/bin/as} into ++@command{/usr/local/libexec/gcc/sparc-sun-solaris2.7/3.4/as}, ++adjusting the latter name to fit your local conventions and software ++version numbers. ++ ++@item ++Install Sun patch 106950-03 (1999-05-25) or later. Nobody with ++both 107058-01 and 106950-03 installed has reported the bug with GCC ++and Sun's dynamic linker. This last course of action is riskiest, ++for two reasons. First, you must install 106950 on all hosts that ++run code generated by GCC; it doesn't suffice to install it only on ++the hosts that run GCC itself. Second, Sun says that 106950-03 is ++only a partial fix for bug 4210064, but Sun doesn't know whether the ++partial fix is adequate for GCC@. Revision -08 or later should fix ++the bug. The current (as of 2004-05-23) revision is -24, and is included in ++the Solaris 7 Recommended Patch Cluster. ++@end itemize ++ ++GCC 3.3 triggers a bug in version 5.0 Alpha 03/27/98 of the Sun assembler, ++which causes a bootstrap failure when linking the 64-bit shared version of ++libgcc.

The ``overall options'' allow you to stop this ++process at an intermediate stage. For example, the @option{-c} option ++says not to run the linker. Then the output consists of object files ++output by the assembler. ++ ++Other options are passed on to one stage of processing. Some options ++control the preprocessor and others the compiler itself. Yet other ++options control the assembler and linker; most of these are not ++documented here, since you rarely need to use any of them. ++ ++@cindex C compilation options ++Most of the command line options that you can use with GCC are useful ++for C programs; when an option is only useful with another language ++(usually C++), the explanation says so explicitly. If the description ++for a particular option does not mention a source language, you can use ++that option with all supported languages. ++ ++@cindex C++ compilation options ++@xref{Invoking G++,,Compiling C++ Programs}, for a summary of special ++options for compiling C++ programs. ++ ++@cindex grouping options ++@cindex options, grouping ++The @command{gcc} program accepts options and file names as operands.

For the most part, the order ++you use doesn't matter. Order does matter when you use several ++options of the same kind; for example, if you specify @option{-L} more ++than once, the directories are searched in the order specified. Also, ++the placement of the @option{-l} option is significant. ++ ++Many options have long names starting with @samp{-f} or with ++@samp{-W}---for example, ++@option{-fmove-loop-invariants}, @option{-Wformat} and so on.

For some targets extra target-specific ++information may also be printed. ++ ++@item --help=@{@var{class}@r{|[}^@r{]}@var{qualifier}@}@r{[},@dots{}@r{]} ++Print (on the standard output) a description of the command line ++options understood by the compiler that fit into all specified classes ++and qualifiers. These are the supported classes: ++ ++@table @asis ++@item @samp{optimizers} ++This will display all of the optimization options supported by the ++compiler. ++ ++@item @samp{warnings} ++This will display all of the options controlling warning messages ++produced by the compiler. ++ ++@item @samp{target} ++This will display target-specific options. Unlike the ++@option{--target-help} option however, target-specific options of the ++linker and assembler will not be displayed.

One ++case where it does work however is when one of the classes is ++@var{target}. So for example to display all the target-specific ++optimization options the following can be used: ++ ++@smallexample ++--help=target,optimizers ++@end smallexample ++ ++The @option{--help=} option can be repeated on the command line.

When this flag is given, it is a ++violation of the ODR to define types with the same name differently. ++ ++@item -fno-weak ++@opindex fno-weak ++Do not use weak symbol support, even if it is provided by the linker. ++By default, G++ will use weak symbols if they are available. This ++option exists only for testing, and should not be used by end-users; ++it will result in inferior code and has no benefits. This option may ++be removed in a future release of G++. ++ ++@item -nostdinc++ ++@opindex nostdinc++ ++Do not search for header files in the standard directories specific to ++C++, but do still search the other standard directories. (This option ++is used when building the C++ library.) ++@end table ++ ++In addition, these optimization, warning, and code generation options ++have meanings only for C++ programs: ++ ++@table @gcctabopt ++@item -fno-default-inline ++@opindex fno-default-inline ++Do not assume @samp{inline} for functions defined inside a class scope. ++@xref{Optimize Options,,Options That Control Optimization}. Note that these ++functions will have linkage like inline functions; they just won't be ++inlined by default. ++ ++@item -Wabi @r{(C, Objective-C, C++ and Objective-C++ only)} ++@opindex Wabi ++@opindex Wno-abi ++Warn when G++ generates code that is probably not compatible with the ++vendor-neutral C++ ABI@. Although an effort has been made to warn about ++all such cases, there are probably some cases that are not warned about, ++even though G++ is generating incompatible code. There may also be ++cases where warnings are emitted even though the code that is generated ++will be compatible. ++ ++You should rewrite your code to avoid these warnings if you are ++concerned about the fact that code generated by G++ may not be binary ++compatible with code generated by other compilers. ++ ++The known incompatibilities at this point include: ++ ++@itemize @bullet ++ ++@item ++Incorrect handling of tail-padding for bit-fields. G++ may attempt to ++pack data into the same byte as a base class. For example: ++ ++@smallexample ++struct A @{ virtual void f(); int f1 : 1; @}; ++struct B : public A @{ int f2 : 1; @}; ++@end smallexample ++ ++@noindent ++In this case, G++ will place @code{B::f2} into the same byte ++as@code{A::f1}; other compilers will not. You can avoid this problem ++by explicitly padding @code{A} so that its size is a multiple of the ++byte size on your platform; that will cause G++ and other compilers to ++layout @code{B} identically. ++ ++@item ++Incorrect handling of tail-padding for virtual bases. G++ does not use ++tail padding when laying out virtual bases. For example: ++ ++@smallexample ++struct A @{ virtual void f(); char c1; @}; ++struct B @{ B(); char c2; @}; ++struct C : public A, public virtual B @{@}; ++@end smallexample ++ ++@noindent ++In this case, G++ will not place @code{B} into the tail-padding for ++@code{A}; other compilers will. You can avoid this problem by ++explicitly padding @code{A} so that its size is a multiple of its ++alignment (ignoring virtual base classes); that will cause G++ and other ++compilers to layout @code{C} identically. ++ ++@item ++Incorrect handling of bit-fields with declared widths greater than that ++of their underlying types, when the bit-fields appear in a union. For ++example: ++ ++@smallexample ++union U @{ int i : 4096; @}; ++@end smallexample ++ ++@noindent ++Assuming that an @code{int} does not have 4096 bits, G++ will make the ++union too small by the number of bits in an @code{int}. ++ ++@item ++Empty classes can be placed at incorrect offsets. For example: ++ ++@smallexample ++struct A @{@}; ++ ++struct B @{ ++ A a; ++ virtual void f (); ++@}; ++ ++struct C : public B, public A @{@}; ++@end smallexample ++ ++@noindent ++G++ will place the @code{A} base class of @code{C} at a nonzero offset; ++it should be placed at offset zero. G++ mistakenly believes that the ++@code{A} data member of @code{B} is already at offset zero. ++ ++@item ++Names of template functions whose types involve @code{typename} or ++template template parameters can be mangled incorrectly. ++ ++@smallexample ++template ++void f(typename Q::X) @{@} ++ ++template
