2020-05-01gcc: Enable bits for sanitizer support on FreeBSD x86_64Andreas Tobler
This patch add the necessary bits to suport libasan on FreeBSD x86_64. gcc * config/i386/i386.h: Define a new macro: SUBTARGET_SHADOW_OFFSET. * config/i386/i386.c (ix86_asan_shadow_offset): Use this macro. * config/i386/darwin.h: Override the SUBTARGET_SHADOW_OFFSET macro. * config/i386/freebsd.h: Likewise. * config/freebsd.h (LIBASAN_EARLY_SPEC): Define. LIBTSAN_EARLY_SPEC): Likewise. (LIBLSAN_EARLY_SPEC): Likewise. libsanitizer: * configure.tgt: Add x86_64- and i?86-*-freebsd* targets.
2020-05-01libsanitizer: Add missing file and regen Makefile.inAndreas Tobler
In the last import the sanitizer_platform_limits_freebsd.cpp got forgotten. Fix this. libsanitizer/sanitizer_common: * Makefile.am: Add sanitizer_platform_limits_freebsd.cpp. * Makefile.in: Regenerate.
2020-03-01Darwin, libsanitizer: Adjust minimum supported Darwin version (PR93731).Iain Sandoe
The current imported libsanitizer code produces kernel panics for Darwin 11 (macOS 10.7) and is unsupported for earlier versions already. It is not clear if the current sources are even intended to be supported on Darwin 11, so this patch causes the default to be build without sanitizers for Darwin <= 11. 2020-03-01 Iain Sandoe <iain@sandoe.co.uk> PR sanitizer/93731 * configure.tgt (x86_64-*-darwin*, i?86-*-darwin*): Enable by default only for Darwin versions greater than 12 (macOS 10.8).
2020-03-01[Darwin, libsanitizer] Default to no sanitizer for Darwin <= 10Iain Sandoe
Darwin10 is no longer supported upstream and will not build without additional patches.
2020-01-24Add `--with-toolexeclibdir=' configuration optionMaciej W. Rozycki
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. In the presence of the `--enable-version-specific-runtime-libs' option and for configurations building native GCC the option is ignored. config/ * toolexeclibdir.m4: New file. gcc/ * doc/install.texi (Cross-Compiler-Specific Options): Document `--with-toolexeclibdir' option. libada/ * Makefile.in (configure_deps): Add `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. libatomic/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libffi/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * include/Makefile.in: Regenerate. * man/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. libgcc/ * Makefile.in (configure_deps): Add `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. libgfortran/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libgomp/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libhsail-rt/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libitm/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libobjc/ * Makefile.in (aclocal_deps): Add `toolexeclibdir.m4'. * aclocal.m4: Include `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. liboffloadmic/ * plugin/configure.ac: Handle `--with-toolexeclibdir='. * plugin/Makefile.in: Regenerate. * plugin/aclocal.m4: Regenerate. * plugin/configure: Regenerate. * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libphobos/ * m4/druntime.m4: Handle `--with-toolexeclibdir='. * m4/Makefile.in: Regenerate. * libdruntime/Makefile.in: Regenerate. * src/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libquadmath/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libsanitizer/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * asan/Makefile.in: Regenerate. * interception/Makefile.in: Regenerate. * libbacktrace/Makefile.in: Regenerate. * lsan/Makefile.in: Regenerate. * sanitizer_common/Makefile.in: Regenerate. * tsan/Makefile.in: Regenerate. * ubsan/Makefile.in: Regenerate. libssp/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libstdc++-v3/ * acinclude.m4: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * doc/Makefile.in: Regenerate. * include/Makefile.in: Regenerate. * libsupc++/Makefile.in: Regenerate. * po/Makefile.in: Regenerate. * python/Makefile.in: Regenerate. * src/Makefile.in: Regenerate. * src/c++11/Makefile.in: Regenerate. * src/c++17/Makefile.in: Regenerate. * src/c++98/Makefile.in: Regenerate. * src/filesystem/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. libvtv/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. zlib/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate.

2019-10-22Arm: Fix arm libsanitizer bootstrap failure Tamar Christina
Glibc has recently introduced changed to the mode field in ipc_perm in commit 2f959dfe849e0646e27403f2e4091536496ac0f0. For Arm this means that the mode field no longer has the same size. This causes an assert failure against libsanitizer's internal copy of ipc_perm. Since this change can't be easily detected I am adding arm to the list of targets that are excluded from this check. libsanitizer doesn't use this field (and others, it in fact uses only 1 field) so this check can be ignored. Padding bits were used by glibc when the field was changed so sizeof and offsets of the remaining fields should be the same. libsanitizer/ChangeLog: PR sanitizer/92154 * sanitizer_common/sanitizer_platform_limits_posix.cpp (defined): Cherry-pick compiler-rt revision r375220.

2019-09-10[ARM/FDPIC v6 03/24] [ARM] FDPIC: Force FDPIC related options unless ↵Christophe Lyon
-mno-fdpic is provided In FDPIC mode, we set -fPIE unless the user provides -fno-PIE, -fpie, -fPIC or -fpic: indeed FDPIC code is PIC, but we want to generate code for executables rather than shared libraries by default. We also make sure to use the --fdpic assembler option, and select the appropriate linker emulation. At link time, we also default to -pie, unless we are generating a shared library or a relocatable file (-r). Note that static link is not supported as it requires specifying the dynamic linker because the executable still has to relocate itself at startup. We also force 'now' binding since lazy binding is not supported. We should also apply the same behavior for -Wl,-Ur as for -r, but I couldn't find how to describe that in the specs fragment. 2019-09-10 Christophe Lyon <christophe.lyon@st.com> Mickaël Guêné <mickael.guene@st.com> gcc/ * config.gcc: Handle arm*-*-uclinuxfdpiceabi. * config/arm/bpabi.h (TARGET_FDPIC_ASM_SPEC): New.

2018-10-31Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).Joseph Myers
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.
