Hi Guys, I am applying the attached patch to sync the top level configure.ac, Makefile.def and Makefile.tpl files with the versions on the gcc mainline development branch. This update brings in the following commits: ------------------------------------------------------------------------ commit b7e5a29602143b53267efcd9c8d5ecc78cd5a62f Author: Tom Tromey Date: Tue Jan 9 06:25:26 2024 -0700 Pass GUILE down to subdirectories When I enable cgen rebuilding in the binutils-gdb tree, the default is to run cgen using 'guile'. However, on my host, guile is guile 2.2, which doesn't work for me -- I have to use guile3.0. This patch arranges to pass "GUILE" down to subdirectories, so I can use 'make GUILE=guile3.0'. commit 725fb3595622a4ad8cd078a42fab1c395cbf90cb Author: Pierre-Emmanuel Patry Date: Wed Oct 25 13:06:48 2023 +0200 build: Add libgrust as compilation modules Define the libgrust directory as a host compilation module as well as for targets. Disable target libgrust if we're not building target libstdc++. commit 56ca59a03150cf44cea340f58967c990ed6bf43c Author: Lewis Hyatt Date: Thu Nov 16 11:18:37 2023 -0500 Makefile.tpl: Avoid race condition in generating site.exp from the top level A command like "make -j 2 check-gcc-c check-gcc-c++" run in the top level of a fresh build directory does not work reliably. That will spawn two independent make processes inside the "gcc" directory, and each of those will attempt to create site.exp if it doesn't exist and will interfere with each other, producing often a corrupted or empty site.exp. Resolve that by making these targets depend on a new phony target which makes sure site.exp is created first before starting the recursive makes. commit 6a6d3817afa02bbcd2388c8e005da6faf88932f1 Author: Iain Sandoe Date: Sun Mar 28 14:48:17 2021 +0100 Config,Darwin: Allow for configuring Darwin to use embedded runpath. 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). commit 2551e10038a70901f30b2168e6e3af4536748f3c Author: Sergei Trofimovich Date: Mon Oct 2 12:08:17 2023 +0100 Makefile.tpl: disable -Werror for feedback stage [PR111663] Without the change profiled bootstrap fails for various warnings on master branch as: $ ../gcc/configure $ make profiledbootstrap ... gcc/genmodes.cc: In function ‘int main(int, char**)’: gcc/genmodes.cc:2152:1: error: ‘gcc/build/genmodes.gcda’ profile count data file not found [-Werror=missing-profile] ... gcc/gengtype-parse.cc: In function ‘void parse_error(const char*, ...)’: gcc/gengtype-parse.cc:142:21: error: ‘%s’ directive argument is null [-Werror=format-overflow=] The change removes -Werror just like autofeedback does today. commit d1bff1ba4d470f6723be83c0e3c4d5083e51877a Author: Thomas Schwinge Date: Thu Jun 1 23:07:37 2023 +0200 Pass 'SYSROOT_CFLAGS_FOR_TARGET' down to target libraries [PR109951] ..., where we need to use it (separate commits) for build-tree testing, similar to 'gcc/Makefile.in:site.exp': # TEST_ALWAYS_FLAGS are flags that should be passed to every compilation. # They are passed first to allow individual tests to override them. @echo "set TEST_ALWAYS_FLAGS \"$(SYSROOT_CFLAGS_FOR_TARGET)\"" >> ./site.tmp PR testsuite/109951 * Makefile.tpl (BASE_TARGET_EXPORTS): Add 'SYSROOT_CFLAGS_FOR_TARGET'. * Makefile.in: Regenerate. ------------------------------------------------------------------------ Cheers Nick
