2020-10-21Introduce vxworks7r2 support for ppc and ppc64Douglas Rupp1-2/+2
This change introduces support for the most recent versions of VxWorks on PowerPC targets, for both 32 and 64 bit thanks to a bi-arch setup. The system compilers are essentially configured as Linux toolchains with only a few specificities and we replicate that model here. The most visible specificities are the use of secureplt by default, the pre-definition of some macros that the system headers still rely on (_VX_CPU and _VX_CPU_FAMILY, for example), and of course some variations related to the so VxWorks typical kernel vs RTP mode distinction. In addition to the introduction of config.gcc and libgcc configuration chunks, much inspired by the linux ones, the change - Reworks rs6000/vxworks.h file to feature bits common to the Vx6 and Vx7 port then a separate section for each, where the Vx7 part is very short as we rely on the Linux definitions for most things. - Adjusts the CPU macro predefinitions in CPP_SPEC to resort to "_VX_CPU" instead of "CPU" for Vx7, to better match the more recent system headers expectations, - Adds a cpu definition case for e6500. - Changes to the use SUB3TARGET_OVERRIDE_OPTIONS instead of SUBSUBTARGET_OVERRIDE_OPTIONS for specifics, so we don't override the Linux's version of the latter for vx7. 2020-10-20 Douglas Rupp <rupp@adacore.com> gcc/ * config.gcc (powerpc*-wrs-vxworks7r*): New case. * config/rs6000/vxworks.h: Rework to handle VxWorks7. Refactor as common bits + vx6 vs vx7 ones. For the latter, rely essentially on the Linux configuration and adjust CPU to _VX_CPU in CPP_SPEC. Add a case for e6500.

2020-04-15aarch64: Fix bootstrap with old binutils [PR93053]Jakub Jelinek1-0/+40
As reported in the PR, GCC 10 (and also 9.3.1 but not 9.3.0) fails to build when using older binutils which lack LSE support, because those instructions are used in libgcc. Thanks to Kyrylo's hint, the following patches (hopefully) allow it to build even with older binutils by using .inst directive if LSE support isn't available in the assembler. 2020-04-15 Jakub Jelinek <jakub@redhat.com> PR target/93053 * configure.ac (LIBGCC_CHECK_AS_LSE): Add HAVE_AS_LSE checking. * config/aarch64/lse.S: Include auto-target.h, if HAVE_AS_LSE is not defined, use just .arch armv8-a.

2020-02-12Use a non-empty test program to test ability to link.Sandra Loosemore1-2/+2
On bare-metal targets, I/O support is typically provided by a BSP and requires a linker script and/or hosting library to be specified on the linker command line. Linking an empty program with the default linker script may succeed, however, which confuses libstdc++ configuration when programs that probe for the presence of various I/O features fail with link errors. 2020-02-12 Sandra Loosemore <sandra@codesourcery.com> PR libstdc++/79193 PR libstdc++/88999 config/ * no-executables.m4: Use a non-empty program to test for linker support. libgcc/ * configure: Regenerated. libgfortran/ * configure: Regenerated. libiberty/ * configure: Regenerated. libitm/ * configure: Regenerated. libobjc/ * configure: Regenerated. libquadmath/ * configure: Regenerated. libssp/ * configure: Regenerated. libstdc++v-3/ * configure: Regenerated.

Provide means, in the form of a `--with-toolexeclibdir=' configuration option, to override the default installation directory for target libraries, otherwise known as $toolexeclibdir. This is so that it is possible to get newly-built libraries, particularly the shared ones, installed in a common place, so that they can be readily used by the target system as their host libraries, possibly over NFS, without a need to manually copy them over from the currently hardcoded location they would otherwise be installed in.

2018-10-31Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).Joseph Myers1-384/+472
This patch updates GCC to use autoconf 2.69 and automake 1.15.1. (That's not the latest automake version, but it's the one used by binutils-gdb, with which consistency is desirable, and in any case seems a useful incremental update that should make a future update to 1.16.1 easier.) The changes are generally similar to the binutils-gdb ones, and are copied from there where shared files and directories are involved (there are some further changes to such shared directories, however, which I'd expect to apply to binutils-gdb once this patch is in GCC). Largely, obsolete AC_PREREQ calls are removed, while many AC_LANG_SOURCE calls are added to avoid warnings from aclocal and autoconf. Multilib support is no longer included in core automake, meaning that multilib.am needs copying from automake's contrib directory into the GCC source tree. Autoconf 2.69 has Go support, so local copies of that support are removed. I hope the D support will soon be submitted to upstream autoconf so the local copy of that can be removed in a future update. Changes to how automake generates runtest calls mean quotes are removed from RUNTEST definitions in five lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm, libphobos, libvtv; some others have RUNTEST definitions without quotes, which are still OK); libgo and libphobos also get -Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST do not generate automake warnings. Note that the regeneration did not include regeneration of fixincludes/config.h.in (attempting such regeneration resulted in all the USED_FOR_TARGET conditionals disappearing; and I don't see anything in the fixincludes/ directory that would result in such conditionals being generated, unlike in the gcc/ directory). Also note that libvtv/testsuite/other-tests/Makefile.in was not regenerated; that directory is not listed as a subdirectory for which Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm not sure how it's meant to be regenerated. While I mostly fixed warnings should running aclocal / automake / autoconf, there were various such warnings from automake in the libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos directories that I did not fix, preferring to leave those to the relevant subsystem maintainers. Specifically, most of those warnings were of the following form (example from libgfortran): Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory, Makefile.am:48: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. I think it's best for the relevant maintainers to add subdir-objects and do any other associated Makefile.am changes needed. In some cases the paths in the warnings involved ../; I don't know if that adds any extra complications to the use of subdir-objects. I've tested this with native, cross and Canadian cross builds. The risk of any OS-specific issues should I hope be rather lower than if a libtool upgrade were included (we *should* do such an upgrade at some point, but it's more complicated - it involves identifying all our local libtool changes to see if any aren't included in the upstream version we update to, and reverting an upstream libtool patch that's inappropriate for use in GCC); I think it would be better to get this update into GCC so that people can test in different configurations and we can fix any issues found, rather than to try to get more and more testing done before it goes in. top level: 2018-10-31 Joseph Myers <joseph@codesourcery.com> PR bootstrap/82856 * multilib.am: New file.

For some targets (in my case VxWorks 5.5), libgcov does not compile due to missing functions and macros such as getpid() and F_OK. Incidentally, gcc/Makefile.in already contains comments such as # Install gcov if it was compiled. but there is no logic in place to actually allow gcov to not be compiled. So add an option for disabling build and install of libgcov and the related host tools. From-SVN: r262180

2017-03-10rs6000: float128 on BE and 32-bitSegher Boessenkool1-5/+7
This fixes float128 on BE and on 32-bit. The configure tests need to use -mabi=altivec for 32-bit, since it is not the default there. That also enables the "vector" keyword, used by the tests. To do this it temporarily adds a few flags to the CFLAGS variable. It also fixes a syntax error in the libgcc_cv_powerpc_float128_hw test (the function name was missing in the function declaration). Regenerating config.in (via autoreconf) removed the duplicate definition of HAVE_SOLARIS_CRTS. Finally, this adds a "-mfloat128-hardware requires -m64" test to rs6000.c: all the current patterns need 64-bit registers. Maybe we'll want to add float128 hardware support to 32-bit some day, but certainly not today. * config/rs6000/rs6000.c (rs6000_option_override_internal): Disallow -mfloat128-hardware without -m64. libgcc/ * configure.ac (test for libgcc_cv_powerpc_float128): Temporarily modify CFLAGS.
