2022-02-24bpf: do not --enable-gcov for bpf-*-* targetsJose E. Marchesi1-3/+11
This patch changes the build machinery in order to disable the build of GCOV (both compiler and libgcc) in bpf-*-* targets. The reason for this change is that BPF is (currently) too restricted in order to support the coverage instrumentalization. Tested in bpf-unknown-none and x86_64-linux-gnu targets. 2022-02-23 Jose E.

2022-01-12aix: handle 64bit inodes for include directoriesClément Chigot1-2/+81
On AIX, stat will store inodes in 32bit even when using LARGE_FILES. If the inode is larger, it will return -1 in st_ino. Thus, in incpath.c when comparing include directories, if several of them have 64bit inodes, they will be considered as duplicated. gcc/ChangeLog: 2022-01-12 Clément Chigot <clement.chigot@atos.net> * configure.ac: Check sizeof ino_t and dev_t.

2021-12-18Darwin: Future-proof and homogeneize detection of darwin versionsFrançois-Xavier Coudert1-1/+1
The current GCC branch will become 12.1.0, which will be the stable version of GCC when the next macOS version is released. There are some places in GCC that don’t handle darwin22 as a version, so we need to future-proof it (gcc/config.gcc and gcc/config/darwin-driver.c). We align that code with what Apple clang does, i.e. accept all potential major macOS versions until 99. This patch also homogenises the handling of darwin version numbers, where the majority of places use darwin2*, but some used darwin2[0-9]*. Since there never was a darwin2.x version, the two are equivalent, and we prefer the simpler darwin2* gcc/ChangeLog: * config/darwin-driver.c: Make version code more future-proof. * config.gcc: Homogeneize darwin versions. * configure.ac: Homogeneize darwin versions. * configure: Regenerate. gcc/testsuite/ChangeLog: * gcc.dg/darwin-minversion-link.c: Test darwin21. * obj-c++.dg/cxx-ivars-3.mm: Homogeneize darwin versions. * obj-c++.dg/objc-gc-3.mm: Homogeneize darwin versions. * objc.dg/objc-gc-4.m: Homogeneize darwin versions.

2021-11-30d: Import dmd b8384668f, druntime e6caaab9, phobos 5ab9ad256 (v2.098.0-beta.1)Iain Buclaw1-2/+105
The D front-end is now itself written in D, in order to build GDC, you will need a working GDC compiler (GCC version 9.1 or later). GCC changes: - Add support for bootstrapping the D front-end. These add the required components in order to have a D front-end written in D itself. Because the compiler front-end only depends on the core runtime modules, only libdruntime is built for the bootstrap stages. D front-end changes: - Import dmd v2.098.0-beta.1. Druntime changes: - Import druntime v2.098.0-beta.1. Phobos changes: - Import phobos v2.098.0-beta.1. The jump from v2.076.1 to v2.098.0 covers nearly 4 years worth of development on the D programming language and run-time libraries. ChangeLog: * Makefile.def: Add bootstrap to libbacktrace, libphobos, zlib, and libatomic. * Makefile.in: Regenerate. * Makefile.tpl (POSTSTAGE1_HOST_EXPORTS): Fix command for GDC.

2021-11-29Make etags path used by build system configurableEric Gallager1-2/+19
This commit allows users to specify a path to their "etags" executable for use when doing "make tags". I based this patch off of this one from upstream automake: https://git.savannah.gnu.org/cgit/automake.git/commit/m4?id=d2ccbd7eb38d6a4277d6f42b994eb5a29b1edf29 This means that I just supplied variables that the user can override for the tags programs, rather than having the configure scripts actually check for them. I handle etags and ctags separately because the intl subdirectory has separate targets for them.

2021-10-28[PATCH 1/5] Makefile.in: Ensure build CPP/CPPFLAGS is used for build targetsRichard Purdie1-1/+1
During cross compiling, CPP is being set to the target compiler even for build targets. As an example, when building a cross compiler targetting mingw, the config.log for libiberty in build.x86_64-pokysdk-mingw32.i586-poky-linux/build-x86_64-linux/libiberty/config.log shows: configure:3786: checking how to run the C preprocessor configure:3856: result: x86_64-pokysdk-mingw32-gcc -E --sysroot=[sysroot]/x86_64-nativesdk-mingw32-pokysdk-mingw32 configure:3876: x86_64-pokysdk-mingw32-gcc -E --sysroot=[sysroot]/x86_64-nativesdk-mingw32-pokysdk-mingw32 conftest.c configure:3876: $? = 0 This is libiberty being built for the build environment, not the target one (i.e. in build-x86_64-linux). As such it should be using the build environment's gcc and not the target one. In the mingw case the system headers are quite different leading to build failures related to not being able to include a process.h file for pem-unix.c. Further analysis shows the same issue occuring for CPPFLAGS too. Fix this by adding support for CPP_FOR_BUILD and CPPFLAGS_FOR_BUILD which for example, avoids mixing the mingw headers for host binaries on linux systems. 2021-10-27 Richard Purdie <richard.purdie@linuxfoundation.org> ChangeLog: * Makefile.tpl: Add CPP_FOR_BUILD and CPPFLAGS_FOR_BUILD support * Makefile.in: Regenerate. * configure: Regenerate. * configure.ac: Add CPP_FOR_BUILD and CPPFLAGS_FOR_BUILD support gcc/ChangeLog: * configure: Regenerate. * configure.ac: Use CPPFLAGS_FOR_BUILD for GMPINC Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2021-09-21arm: pass architecture extensions to assembler if supportedRichard Earnshaw1-0/+35
When I originally added the new extended architecture features support to GCC, the assembler was unable to parse the new feature lists on the command-line and would throw an error. This has now been fixed in GAS and the behaviour is the same as GCC. So this patch adds a configure-time test for the assembler in use to detect that it is recent enough to support this behaviour and then enables passing the architecture extensions to the assembler when this is the case. Although the assembly output generated by GCC does not rely on this, this should ease some issues when using GCC as a driver for compiling source written directly in assembly language when the programmer was expecting the appropriate options to be passed on the command line. gcc/ChangeLog: * configure.ac: Detect when the assembler supports new-style architecture extensions. * common/config/arm/arm-common.c (arm_rewrite_mcpu): Return the full CPU string if the assembler can grok it. (arm_rewrite_march): Likewise but for the architecture. * config.in: Regenerate. * configure: Regenerate.
2021-09-14configure: Avoid unnecessary constraints on executables for $build.Iain Sandoe1-16/+2
The executables for GCC's c-family compilers must be built with no-PIE because they use PCH and the current model for this requires that the exe is always lauched at the same address. Since the other language compilers share code with the c-family this constraint is also applied to them. However, the executables that run on $build (generators, and parsers for md and def files) need not have any such constraint they do not consume PCH files. This change simplifies the configuration and Makefile content by removing the code enforcing no-PIE on these exes. This also fixes a bootstrap issue with some Darwin versions and clang as the bootstrap compiler, where -no-PIE causes the correct relocation model to be switched off leading to invalid user-space code. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> gcc/ChangeLog: * Makefile.in: Remove variables related to applying no-PIE to the exes on $build. * configure: Regenerate. * configure.ac: Remove configuration related to applying no-PIE to the exes on $build.

Special-casing checks for in-tree gas features is unnecessary since r100007 which made configure-gcc depend on all-gas, and thus making alternate code path in gcc_GAS_CHECK_FEATURE for in-tree gas redundant.

2021-04-21aarch64: Always use .init/.fini_array for GNU/LinuxRichard Sandiford1-2/+12
I was wondering why the (now fixed) c-c++-common/attr-retain-[78].c failures were showing up in the native results for aarch64-linux-gnu but not in the posted cross results. It turns out that .init/ .fini_array support is disabled by default for cross builds, which in turn stops those tests from running. The test for .init/fini_array support has two parts: one that builds something with the assembler and linker, and another that compiles C code and uses preprocessor macros to test the glibc version. The first test would work with build=host but the second is only safe for build=target. However, AArch64 postdates glibc and binutils support for .init/fini_array by some distance, so it's safe to hard-code the result to "yes" for cross compilers. This fixes the only material difference in auto-host.h between a native and a cross build. gcc/ * acinclude.m4 (gcc_AC_INITFINI_ARRAY): When cross-compiling, default to yes for aarch64-linux-gnu. * configure: Regenerate.
2021-03-31i386, debug: Default to -gdwarf-4 on Windows targets with broken ld.bfd ↵Jakub Jelinek1-13/+31
[PR98860] As mentioned in the PR, before the https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=ba6eb62ff0ea9843a018cfd7cd06777bd66ae0a0 fix from March 1st, PECOFF ld.bfd didn't know about .debug_loclists, .debug_rnglists and other debug sections new in DWARF 5. Unfortunately, unlike for ELF linkers, that means the sections were placed in wrong ordering with wrong VMA/LMA, so the resulting executables are apparently unusable. As that is pretty new change, newer than 2.35.2 or 2.36 binutils releases, the following patch adds a workaround that turns -gdwarf-4 by default instead of -gdwarf-5 if a broken linker is found at configure time. Users can still explicitly play with -gdwarf-5 and either use a non-broken linker or use custom linker scripts for the broken one, but at least by default it should work. 2021-03-31 Jakub Jelinek <jakub@redhat.com> PR bootstrap/98860 * configure.ac (HAVE_LD_BROKEN_PE_DWARF5): New AC_DEFINE if PECOFF linker doesn't support DWARF sections new in DWARF5. * config/i386/i386-options.c (ix86_option_override_internal): Default to dwarf_version 4 if HAVE_LD_BROKEN_PE_DWARF5 for TARGET_PECOFF targets. * config.in: Regenerated. * configure: Regenerated.
2021-01-25configure: Add workaround for buggy binutils 2.35 [PR98811]Jakub Jelinek1-1/+5
binutils since https://sourceware.org/bugzilla/show_bug.cgi?id=25612 changes from March last year until the https://sourceware.org/pipermail/binutils/2020-August/112684.html fix in early August emits incorrect .debug_info when assembling files with --gdwarf-5. Instead of emitting proper DWARF 5 .debug_info header, it emits DWARF 4 .debug_info header with 5 as the dwarf version instead of 4. This results e.g. in libgcc.a (morestack.o) having garbage in its .debug_info sections and e.g. libbacktrace during pretty much all libgo tests fails miserably. The following patch adds a workaround for that, don't set HAVE_AS_GDWARF_5_DEBUG_FLAG if readelf can't read the .debug_info back. Built tested on x86_64-linux against both binutils 2.35 (buggy ones) and latest binutils trunk, the former with the patch now has DWARF 3 .debug_line and DWARF 2 .debug_info in morestack.o, while the latter as before correct DWARF 5 .debug_line and .debug_info. 2021-01-25 Jakub Jelinek <jakub@redhat.com> PR debug/98811 * configure.ac (HAVE_AS_GDWARF_5_DEBUG_FLAG): Only define if readelf -wi is able to read the emitted .debug_info back. * configure: Regenerated.
2021-01-12configure, make: Fix up --enable-link-serializationJakub Jelinek1-1/+6
As reported by Matthias, --enable-link-serialization=1 can currently start two concurrent links first (e.g. gnat1 and cc1). The problem is that make var = value values seem to work differently between dependencies and actual rules (where it was tested). As the language make fragments can be in different order, we can have: ada.prev = ... magic that will become $(c.serial) under --enable-link-serialization=1 gnat1$(exe): ..... $(ada.prev) ... c.serial = cc1$(exe) and while if I add echo $(ada.prev) in the gnat1 rule's command, it prints cc1, the dependencies are actually evaluated during reading of the goal or when. The configure creates (and puts into Makefile) some serialization order of the languages and in that order c always comes first, and the rest is actually sorted the way the all_lang_makefrags are already sorted, so just by forcing c/Make-lang.in first we achieve that X.serial variable is always defined before some other Y.prev will use it in its goal dependencies. 2021-01-12 Jakub Jelinek <jakub@redhat.com> * configure.ac: Ensure c/Make-lang.in comes first in @all_lang_makefrags@. * configure: Regenerated.

2021-01-05build: libcody: Link with -lsocket -lnsl if necessary [PR98316]Rainer Orth1-2/+167
With the introduction of C++20 modules and libcody, cc1plus and cc1objplus gained a dependency on the socket functions. Before those were merged into libc in Solaris 11.4, one needed to link with -lsocket -lnsl on Solaris, so that merge broke the Solaris 11.3 build. While we already have 4 different checks for those libraries in the tree, I decided to import autoconf-archive's AX_LIB_SOCKET_NSL macro instead. At the same time, the patch only links libcody and the networking libs where needed (cc1plus, cc1objplus).

This is the same option spelling as that used by clang to allow the use of libstdc++. The availability (and thus function) of the option are a configure-time choice using the configuration control: --with-gxx-libcxx-include-dir= Specification of the path for the libc++ headers, enables the -stdlib= option (using the path as given), default values are set when the path is unconfigured. If --with-gxx-libcxx-include-dir is given together with --with-sysroot=, then we test to see if the include path starts with the sysroot and, if so, record the sysroot-relative component as the local path. At runtime, we prepend the sysroot that is actually active. At link time, we use the C++ runtime in force and (if that is libc++) also append the libc++abi ABI library. As for other cases, if a target sets the name pointer for the ABI library to NULL the G++ driver will omit it from the link line. gcc/ChangeLog: * configure.ac: Add gxx-libcxx-include-dir handled in the same way as the regular cxx header directory. * Makefile.in: Regenerated. * config.in: Likewise. * configure: Likewise. * cppdefault.c: Pick up libc++ headers if the option is enabled. * cppdefault.h (struct default_include): Amend comments to reflect the extended use of the cplusplus field. * incpath.c (add_standard_paths): Allow for multiple c++ header include path variants. * doc/invoke.texi: Document the -stdlib= option. gcc/c-family/ChangeLog: * c.opt: Add -stdlib= option and enumerations for libstdc++ and libc++. gcc/cp/ChangeLog: * g++spec.c (LIBCXX, LIBCXX_PROFILE, LIBCXX_STATIC): New. (LIBCXXABI, LIBCXXABI_PROFILE, LIBCXXABI_STATIC): New. (enum stdcxxlib_kind): New. (lang_specific_driver): Allow selection amongst multiple c++ runtime libraries.
2020-12-17IBM Z: Detect libc's float_t behavior on cross compilesMarius Hillenbrand1-23/+44
When cross-compiling GCC with target libc headers available and configure option --enable-s390-excess-float-precision has been omitted, identify whether they clamp float_t to double or respect __FLT_EVAL_METHOD__ via a compile test that coerces the build-system compiler to use the target headers. Then derive the setting from that. gcc/ChangeLog: 2020-12-16 Marius Hillenbrand <mhillen@linux.ibm.com> * configure.ac: Change --enable-s390-excess-float-precision default behavior for cross compiles with target headers. * configure: Regenerate. * doc/install.texi: Adjust documentation.
