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}.

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.

(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.

(Confusion may also -+result if the compiler finds the GNU assembler but has not been -+configured with @option{--with-gnu-as}.)

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. Option @option{--disable-initfini-array} has the -+opposite effect. If neither option is specified, the configure script -+will try to guess whether the @code{.init_array} and -+@code{.fini_array} sections are supported and, if they are, use them. -+ -+@item --enable-maintainer-mode -+The build rules that -+regenerate the GCC master message catalog @file{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 @option{--enable-maintainer-mode} will enable -+this. Note that you need a recent version of the @code{gettext} tools -+to do so. -+ -+@item --disable-bootstrap -+For a native build, the default configuration is to perform -+a 3-stage bootstrap of the compiler when @samp{make} is invoked, -+testing that GCC can compile itself correctly. If you want to disable -+this process, you can configure with @option{--disable-bootstrap}. -+ -+@item --enable-bootstrap -+In special cases, you may want to perform a 3-stage build -+even if the target and host triplets are different. -+This could happen 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 @option{--enable-bootstrap}. -+ -+@item --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 @option{--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. -+ -+@item --enable-version-specific-runtime-libs -+Specify -+that runtime libraries should be installed in the compiler specific -+subdirectory (@file{@var{libdir}/gcc}) rather than the usual places. In -+addition, @samp{libstdc++}'s include files will be installed into -+@file{@var{libdir}} unless you overruled it by using -+@option{--with-gxx-include-dir=@var{dirname}}. Using this option is -+particularly useful if you intend to use several versions of GCC in -+parallel. This is currently supported by @samp{libgfortran}, -+@samp{libjava}, @samp{libmudflap}, @samp{libstdc++}, and @samp{libobjc}. -+ -+@item --enable-languages=@var{lang1},@var{lang2},@dots{} -+Specify that only a particular subset of compilers and -+their runtime libraries should be built.

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. 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. -+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 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 @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.

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. If this option is unspecified or -+disabled, @samp{gcj} is invoked once for each @file{.java} -+file to compile into a @file{.class} file. -+ -+@item --with-libiconv-prefix=DIR -+Search for libiconv in @file{DIR/include} and @file{DIR/lib}. -+ -+@item --enable-sjlj-exceptions -+Force use of the @code{setjmp}/@code{longjmp}-based scheme for exceptions. -+@samp{configure} ordinarily picks the correct value based on the platform. -+Only use this option if you are sure you need a different setting. -+ -+@item --with-system-zlib -+Use installed @samp{zlib} rather than that included with GCC@. -+ -+@item --with-win32-nlsapi=ansi, unicows or unicode -+Indicates how MinGW @samp{libgcj} translates between UNICODE -+characters and the Win32 API@. -+ -+@item --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. -+ -+@item --with-arch-directory=ARCH -+Specifies the name to use for the @file{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. -+ -+@item --with-os-directory=DIR -+Specifies the OS directory for the SDK include directory. This is set to auto -+detect, and is typically 'linux'. -+ -+@item --with-origin-name=NAME -+Specifies the JPackage origin name. This defaults to the 'gcj' in -+java-1.5.0-gcj. -+ -+@item --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'. -+ -+@item --with-jvm-root-dir=DIR -+Specifies where to install the SDK. Default is $(prefix)/lib/jvm. -+ -+@item --with-jvm-jar-dir=DIR -+Specifies where to install jars. Default is $(prefix)/lib/jvm-exports. -+ -+@item --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. -+ -+@item --enable-aot-compile-rpm -+Adds aot-compile-rpm to the list of installed scripts. -+ -+@table @code -+@item ansi -+Use the single-byte @code{char} and the Win32 A functions natively, -+translating to and from UNICODE when using these functions. If -+unspecified, this is the default. -+ -+@item unicows -+Use the @code{WCHAR} and Win32 W functions natively. Adds -+@code{-lunicows} to @file{libgcj.spec} to link with @samp{libunicows}. -+@file{unicows.dll} needs to be deployed on Microsoft Windows 9X machines -+running built executables. @file{libunicows.a}, an open-source -+import library around Microsoft's @code{unicows.dll}, is obtained from -+@uref{http://libunicows.sourceforge.net/}, which also gives details -+on getting @file{unicows.dll} from Microsoft. -+ -+@item unicode -+Use the @code{WCHAR} and Win32 W functions natively.

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 -+@option{--disable-werror}. -+ -+On certain old systems, defining certain environment variables such as -+@env{CC} can interfere with the functioning of @command{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 @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.

-+@end html -+@heading @anchor{alpha-dec-osf}alpha*-dec-osf* -+Systems using processors that implement the DEC Alpha architecture and -+are running the DEC/Compaq Unix (DEC OSF/1, Digital UNIX, or Compaq -+Tru64 UNIX) operating system, for example the DEC Alpha AXP systems. -+ -+As of GCC 3.2, versions before @code{alpha*-dec-osf4} are no longer -+supported. (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 -+

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.

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.

During the stage1 phase of -+the build, the native AIX compiler @strong{must} be invoked as @command{cc} -+(not @command{xlc}).

-+@end html -+@heading @anchor{older}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 -+@command{configure} will fail unless the @option{--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 -+@file{old-releases} directory on the @uref{../mirrors.html,,GCC mirror -+sites}. Header bugs may generally be avoided using -+@command{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), patches -+@uref{../contribute.html,,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 @file{pub/binutils/old-releases} on -+@uref{http://sourceware.org/mirrors.html,,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. -+ -+@html -+

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. Many -+options have multi-letter names; therefore multiple single-letter options -+may @emph{not} be grouped: @option{-dv} is very different from @w{@samp{-d -+-v}}. -+ -+@cindex order of options -+@cindex options, order -+You can mix options and other arguments. 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. Most of -+these have both positive and negative forms; the negative form of -+@option{-ffoo} would be @option{-fno-foo}.

This will allow -+intermodule analysis (IMA) to be performed by the compiler. Currently the only -+language for which this is supported is C@. If you pass source files for -+multiple languages to the driver, using this option, the driver will invoke -+the compiler(s) that support IMA once each, passing each compiler all the -+source files appropriate for it. For those languages that do not support -+IMA this option will be ignored, and the compiler will be invoked once for -+each source file in that language. If you use this option in conjunction -+with @option{-save-temps}, the compiler will generate multiple -+pre-processed files -+(one for each source file), but only one (combined) @file{.o} or -+@file{.s} file. -+ -+@item --help -+@opindex help -+Print (on the standard output) a description of the command line options -+understood by @command{gcc}. If the @option{-v} option is also specified -+then @option{--help} will also be passed on to the various processes -+invoked by @command{gcc}, so that they can display the command line options -+they accept. If the @option{-Wextra} option has also been specified -+(prior to the @option{--help} option), then command line options which -+have no documentation associated with them will also be displayed. -+ -+@item --target-help -+@opindex target-help -+Print (on the standard output) a description of target-specific command -+line options for each tool. 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. This is because those -+tools do not currently support the extended @option{--help=} syntax. -+ -+@item @samp{params} -+This will display the values recognized by the @option{--param} -+option. -+ -+@item @var{language} -+This will display the options supported for @var{language}, where -+@var{language} is the name of one of the languages supported in this -+version of GCC. -+ -+@item @samp{common} -+This will display the options that are common to all languages. -+@end table -+ -+These are the supported qualifiers: -+ -+@table @asis -+@item @samp{undocumented} -+Display only those options which are undocumented. -+ -+@item @samp{joined} -+Display options which take an argument that appears after an equal -+sign in the same continuous piece of text, such as: -+@samp{--help=target}. -+ -+@item @samp{separate} -+Display options which take an argument that appears as a separate word -+following the original option, such as: @samp{-o output-file}. -+@end table -+ -+Thus for example to display all the undocumented target-specific -+switches supported by the compiler the following can be used: -+ -+@smallexample -+--help=target,undocumented -+@end smallexample -+ -+The sense of a qualifier can be inverted by prefixing it with the -+@samp{^} character, so for example to display all binary warning -+options (i.e., ones that are either on or off and that do not take an -+argument), which have a description the following can be used: -+ -+@smallexample -+--help=warnings,^joined,^undocumented -+@end smallexample -+ -+The argument to @option{--help=} should not consist solely of inverted -+qualifiers. -+ -+Combining several classes is possible, although this usually -+restricts the output by so much that there is nothing to display. 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. Each -+successive use will display its requested class of options, skipping -+those that have already been displayed. -+ -+If the @option{-Q} option appears on the command line before the -+@option{--help=} option, then the descriptive text displayed by -+@option{--help=} is changed. Instead of describing the displayed -+options, an indication is given as to whether the option is enabled, -+disabled or set to a specific value (assuming that the compiler -+knows this at the point where the @option{--help=} option is used). -+ -+Here is a truncated example from the ARM port of @command{gcc}: -+ -+@smallexample -+ % gcc -Q -mabi=2 --help=target -c -+ The following options are target specific: -+ -mabi= 2 -+ -mabort-on-noreturn [disabled] -+ -mapcs [disabled] -+@end smallexample -+ -+The output is sensitive to the effects of previous command line -+options, so for example it is possible to find out which optimizations -+are enabled at @option{-O2} by using: -+ -+@smallexample -+-Q -O2 --help=optimizers -+@end smallexample -+ -+Alternatively you can discover which binary optimizations are enabled -+by @option{-O3} by using: -+ -+@smallexample -+gcc -c -Q -O3 --help=optimizers > /tmp/O3-opts -+gcc -c -Q -O2 --help=optimizers > /tmp/O2-opts -+diff /tmp/O2-opts /tmp/O3-opts | grep enabled -+@end smallexample -+ -+@item --version -+@opindex version -+Display the version number and copyrights of the invoked GCC@. -+ -+@item -wrapper -+@opindex wrapper -+Invoke all subcommands under a wrapper program.

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.
