2025-05-21[PATCH] configure: Always add pre-installed header directories to search pathStephanos Ioannidis1-6/+10
configure script was adding the target directory flags, including the '-B' flags for the executable prefix and the '-isystem' flags for the pre-installed header directories, to the target flags only for non-Canadian builds under the premise that the host binaries under the executable prefix will not be able to execute on the build system for Canadian builds. While that is true for the '-B' flags specifying the executable prefix, the '-isystem' flags specifying the pre-installed header directories are not affected by this and do not need special handling. This patch updates the configure script to always add the 'include' and 'sys-include' pre-installed header directories to the target search path, in order to ensure that the availability of the pre-installed header directories in the search path is consistent across non-Canadian and Canadian builds. When '--with-headers' flag is specified, this effectively ensures that the libc headers, that are copied from the specified header directory to the sys-include directory, are used by libstdc++. * configure.ac: Always add pre-installed heades to search path. * configure: Regenerate.

2025-04-02config, toplevel, Darwin: Pass -B instead of -L to C++ commands.Iain Sandoe1-2/+98
Darwin from 10.11 needs embedded rpaths to find the correct libraries at runtime. Recent increases in hardening have made it such that the dynamic loader will no longer fall back to using an installed libstdc++ when the (new) linked one is not found. This means we fail configure tests (that should pass) for runtimes that use C++. We can resolve this by passing '-B' to the C++ command lines instead of '-L' (-B implies -L on Darwin, but also causes a corresponding embedded rpath). ChangeLog: * configure: Regenerate. * configure.ac: Use -B instead of -L to specifiy the C++ runtime paths on Darwin. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>

2025-03-14GCN, nvptx: Don't default-disable libstdc++ buildThomas Schwinge1-5/+11
In addition to making libstdc++ itself available, this, via enabling 'build-gcc/*/libstdc++-v3/scripts/testsuite_flags', in particular also makes the standard C++ headers available to 'make check-gcc-c++'. With that, there are a lot of FAIL/UNRESOLVED -> PASS progressions, where we previously ran into, for example: FAIL: g++.dg/coroutines/co-await-syntax-00-needs-expr.C (test for errors, line 6) FAIL: g++.dg/coroutines/co-await-syntax-00-needs-expr.C (test for excess errors) Excess errors: [...]/gcc/testsuite/g++.dg/coroutines/coro.h:132:10: fatal error: cstdlib: No such file or directory Similarly, there are a lot of FAIL/UNRESOLVED -> UNSUPPORTED "progressions" due to 'sorry, unimplemented: exception handling not supported'. The 'make check-target-libstdc++-v3' results don't look too bad, either. This also reverts Subversion r221362 (Git commit d94fae044da071381b73a2ee8afa874b14fa3820) "No libstdc++ for nvptx", and commit 2f4f3c0e9345805160ecacd6de527b519a8c9206 "No libstdc++ for GCN". With libstdc++ now available, libgrust gets enabled, which we in turn again have to disable, for 'sorry, unimplemented: exception handling not supported' reasons.

2025-03-11cobol: Fix up libgcobol configure [PR119216]Jakub Jelinek1-1/+1
Sorry, seems I've screwed up the earlier libgcobol/configure.tgt change. Looking in more detail, the way e.g. libsanitizer/configure.tgt works is that it is sourced twice, once at toplevel and there it just sets UNSUPPORTED=1 for fully unsupported triplets, and then inside of libsanitizer/configure where it decides to include or not include the various sublibraries depending on the *_SUPPORTED flags. So, the following patch attempts to do the same for libgcobol as well. The BIULD_LIBGCOBOL automake conditional was unused, this patch guards it on LIBGCOBOL_SUPPORTED as well and guards with it toolexeclib_LTLIBRARIES = libgcobol.la Also, AM_CFLAGS has been changed to AM_CXXFLAGS as there are just C++ sources in the library. 2025-03-11 Jakub Jelinek <jakub@redhat.com> PR cobol/119216 * configure.ac: Check for UNSUPPORTED set by libgcobol/configure.tgt rather than LIBGCOBOL_SUPPORTED. * configure: Regenerate. libgcobol/ * configure.tgt: On fully unsupported targets set UNSUPPORTED=1. * configure.ac: Add AC_CHECK_SIZEOF([void *]), source in configure.tgt and set BUILD_LIBGCOBOL also based on LIBGCOBOL_SUPPORTED. * Makefile.am (toolexeclib_LTLIBRARIES): Conditionalize on BUILD_LIBGCOBOL.

This syncs us with binutils/gdb's toplevel configure as of 987db70acefd0b223a8df2240d4e5ca544cc0a91. There's not much notable here, just gprofng (which is in binutils) being disabled for musl and a new target which got added on that side too. The only part which may look interesting is the baseargs->bbaseargs change which goes back to Arsen's gettext work and a fixup which landed for that on the binutils side in 9c0aa4c53104b1c4333d55aeaf11b41053307929. * configure: Regenerate. * configure.ac: Sync with Binutils.

2024-10-28build: update bootstrap req to C++14Jason Merrill1-56/+776
We moved to a bootstrap requirement of C++11 in GCC 11, 8 years after support was stable in GCC 4.8. It is now 8 years since C++14 was the default mode in GCC 6 (and 9 years since support was complete in GCC 5), and we have a few bits of optional C++14 code in the compiler, so it seems a good time to update the bootstrap requirement again. The big benefit of the change is the greater constexpr power, but C++14 also added variable templates, generic lambdas, lambda init-capture, binary literals, and numeric literal digit separators. C++14 was feature-complete in GCC 5, and became the default in GCC 6. 5.4.0 bootstraps trunk correctly; trunk stage1 built with 5.3.0 breaks in eh_data_format_name due to PR69995. gcc/ChangeLog: * doc/install.texi (Prerequisites): Update to C++14.

2023-11-14*: add modern gettextArsen Arsenović1-11/+33
This patch updates gettext.m4 and related .m4 files and adds gettext-runtime as a gmp/mpfr/... style host library, allowing newer libintl to be used. This patch /does not/ add build-time tools required for internationalizing (msgfmt et al), instead, it just updates the runtime library. The result should be a distribution that acts exactly the same when a copy of gettext is present, and disables internationalization otherwise. There should be no changes in behavior when gettext is included in-tree. When gettext is not included in tree, nor available on the system, the programs will be built without localization. ChangeLog: PR bootstrap/12596 * .gitignore: Add '/gettext*'. * configure.ac (host_libs): Replace intl with gettext. (hbaseargs, bbaseargs, baseargs): Split baseargs into {h,b}baseargs.

2023-10-22Config,Darwin: Allow for configuring Darwin to use embedded runpath.Iain Sandoe1-0/+14
Recent Darwin versions place contraints on the use of run paths specified in environment variables. This breaks some assumptions in the GCC build. This change allows the user to configure a Darwin build to use '@rpath/libraryname.dylib' in library names and then to add an embedded runpath to executables (and libraries with dependents). The embedded runpath is added by default unless the user adds '-nodefaultrpaths' to the link line. For an installed compiler, it means that any executable built with that compiler will reference the runtimes installed with the compiler (equivalent to hard-coding the library path into the name of the library). During build-time configurations any "-B" entries will be added to the runpath thus the newly-built libraries will be found by exes. Since the install name is set in libtool, that decision needs to be available here (but might also cause dependent ones in Makefiles, so we need to export a conditional). This facility is not available for Darwin 8 or earlier, however the existing environment variable runpath does work there. We default this on for systems where the external DYLD_LIBRARY_PATH does not work and off for Darwin 8 or earlier. For systems that can use either method, if the value is unset, we use the default (which is currently DYLD_LIBRARY_PATH). ChangeLog: * configure: Regenerate. * configure.ac: Do not add default runpaths to GCC exes when we are building -static-libstdc++/-static-libgcc (the default). * libtool.m4: Add 'enable-darwin-at-runpath'.

2023-09-15LoongArch: Reimplement multilib build option handling.Yang Yujie1-0/+6
Library build options from --with-multilib-list used to be processed with *self_spec, which missed the driver's initial canonicalization. This caused limitations on CFLAGS override and the use of driver-only options like -m[no]-lsx. The problem is solved by promoting the injection rules of --with-multilib-list options to the first element of DRIVER_SELF_SPECS, to make them execute before the canonialization. The library-build options are also hard-coded in the driver and can be used conveniently by the builders of other non-gcc libraries via the use of -fmultiflags. Bootstrapped and tested on loongarch64-linux-gnu. ChangeLog: * config-ml.in: Remove unneeded loongarch clause. * configure.ac: Register custom makefile fragments mt-loongarch-* for loongarch targets. * configure: Regenerate. config/ChangeLog: * mt-loongarch-mlib: New file.

2023-08-07Pass PKG_CONFIG_PATH down from top-level MakefileSimon Marchi1-0/+2
[Sending to binutils, gdb-patches and gcc-patches, since it touches the top-level Makefile/configure] I have my debuginfod library installed in a non-standard location (/opt/debuginfod), which requires me to set PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config. If I just set it during configure: $ PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config ./configure --with-debuginfod $ make or $ ./configure --with-debuginfod PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config $ make Then PKG_CONFIG_PATH is only present (and ignored) during the top-level configure. When running make (which runs gdb's and binutils' configure), PKG_CONFIG_PATH is not set, which results in their configure script not finding the library: checking for libdebuginfod >= 0.179... no configure: error: "--with-debuginfod was given, but libdebuginfod is missing or unusable." Change the top-level configure/Makefile system to capture the value passed when configuring the top-level and pass it down to subdirectories (similar to CFLAGS, LDFLAGS, etc). I don't know much about the top-level build system, so I really don't know if I did this correctly. The changes are: - Use AC_SUBST(PKG_CONFIG_PATH) in configure.ac, so that @PKG_CONFIG_PATH@ gets replaced with the actual PKG_CONFIG_PATH value in config files (i.e. Makefile) - Add a PKG_CONFIG_PATH Makefile variable in Makefile.tpl, initialized to @PKG_CONFIG_PATH@ - Add PKG_CONFIG_PATH to HOST_EXPORTS in Makefile.tpl, which are the variables set when running the sub-configures I initially added PKG_CONFIG_PATH to flags_to_pass, in Makefile.def, but I don't think it's needed. AFAIU, this defines the flags to pass down when calling "make" in subdirectories. We only need PKG_CONFIG_PATH to be passed down during configure. After that, it's captured in gdb/config.status, so even if a "make" causes a re-configure later (because gdb/configure has changed, for example), the PKG_CONFIG_PATH value will be remembered. Change-Id: I91138dfca41c43b05e53e445f62e4b27882536bf ChangeLog: * configure.ac: Add AC_SUBST(PKG_CONFIG_PATH). * configure: Re-generate. * Makefile.tpl (HOST_EXPORTS): Pass PKG_CONFIG_PATH. (PKG_CONFIG_PATH): New. * Makefile.in: Re-generate.
2023-08-07Disable year 2038 support on 32-bit hosts by defaultLuis Machado1-0/+22
With a recent import of gnulib, code has been pulled that tests and enables 64-bit time_t by default on 32-bit hosts that support it. Although gdb can use the gnulib support, bfd doesn't use gnulib and currently doesn't do these checks. As a consequence, if we have a 32-bit host that supports 64-bit time_t, we'll have a mismatch between gdb's notion of time_t and bfd's notion of time_t. This will lead to mismatches in the struct stat size, leading to memory corruption and crashes. This patch disables the year 2038 check for now, which makes things work reliably again. I'd consider this a temporary fix until we have proper bfd checks for the year 2038, if it makes sense. 64-bit hosts seems to be more common these days, so I'm not sure how important it is to have this support enabled and how soon we want to enable it. Thoughts? ChangeLog: * configure.ac: Disable year2038 by default on 32-bit hosts. * configure: Regenerate.

2023-06-25configure, Darwin: Ensure overrides to host-pie are passed to gcc configure.Iain Sandoe1-12/+36
The latest versions of Darwin on the Aarch64 platform mandate PIE executables. On x86_64 it remains optional, but produces tool warnings after Darwin20, so we default to PIE executables there too. All (non-PowerPC) 64b Darwin platforms mandate PIC code and therefore force host_shared on (we issue a diagnostic if the user tries to configure them non-shared). However, this also means we cannot test the host_shared setting independently of the host_pie setting so that the logic for setting PICFLAG must be amended for Darwin. For Darwin versions required to have PIE executables, in the event that the user tries to configure these as --disable-host-pie, we issue a warning and override the setting. These versions must also switch host_pie on even if it is not given in the configure line. To cater for this we pass the current value of host_pie, as determined by top-level configure, to the GCC configure. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> ChangeLog: * Makefile.def: Pass the enable-host-pie value to GCC configure. * Makefile.in: Regenerate. * configure: Regenerate. * configure.ac: Adjust the logic for shared and PIE host flags to ensure that PIE is passed for hosts that require it.
2023-06-15configure: Implement --enable-host-pieMarek Polacek1-2/+47
[ This is my third attempt to add this configure option. The first version was approved but it came too late in the development cycle. The second version was also approved, but I had to revert it: <https://gcc.gnu.org/pipermail/gcc-patches/2022-November/607082.html>. I've fixed the problem (by moving $(PICFLAG) from INTERNAL_CFLAGS to ALL_COMPILERFLAGS). Another change is that since r13-4536 I no longer need to touch Makefile.def, so this patch is simplified. ] This patch implements the --enable-host-pie configure option which makes the compiler executables PIE. This can be used to enhance protection against ROP attacks, and can be viewed as part of a wider trend to harden binaries. It is similar to the option --enable-host-shared, except that --e-h-s won't add -shared to the linker flags whereas --e-h-p will add -pie. It is different from --enable-default-pie because that option just adds an implicit -fPIE/-pie when the compiler is invoked, but the compiler itself isn't PIE. Since r12-5768-gfe7c3ecf, PCH works well with PIE, so there are no PCH regressions. When building the compiler, the build process may use various in-tree libraries; these need to be built with -fPIE so that it's possible to use them when building a PIE. For instance, when --with-included-gettext is in effect, intl object files must be compiled with -fPIE. Similarly, when building in-tree gmp, isl, mpfr and mpc, they must be compiled with -fPIE.
