libsanitizer merge from upstream r191666 This may break gcc-asan on Mac, will follow up separately. From-SVN: r204368 2013-11-04 22:33:31 +01:00			`# This file is used to maintain libtool version info for libasan. See`
Import the asan runtime library into GCC tree This patch imports the runtime library in the GCC tree, ensures that -lasan is passed to the linker when -faddress-sanitizer is used and sets up the build system accordingly. ChangeLog: * configure.ac: Add libsanitizer to target_libraries. * Makefile.def: Ditto. * configure: Regenerate. * Makefile.in: Regenerate. * libsanitizer: New directory for asan runtime. Contains an empty tsan directory. gcc/ChangeLog: * gcc.c (LINK_COMMAND_SPEC): Add -laddress-sanitizer to link command if -faddress-sanitizer is on. libsanitizer: Initial checkin: migrate asan runtime from llvm.

libsanitizer: Bump asan/tsan versions Bump asan/tsan versions for upstream commits: commit f1bb30a4956f83e46406d6082e5d376ce65391e0 Author: Vitaly Buka <vitalybuka@google.com> Date: Thu Aug 26 10:25:09 2021 -0700 [sanitizer] No THREADLOCAL in qsort and bsearch qsort can reuse qsort_r if available. bsearch always passes key as the first comparator argument, so we can use it to wrap the original comparator. Differential Revision: https://reviews.llvm.org/D108751 commit d77b476c1953bcb0a608b2d6a4f2dd9fe0b43967 Author: Dmitry Vyukov <dvyukov@google.com> Date: Mon Aug 2 16:52:53 2021 +0200 tsan: avoid extra call indirection in unaligned access functions Currently unaligned access functions are defined in tsan_interface.cpp and do a real call to MemoryAccess. This means we have a real call and no read/write constant propagation. Unaligned memory access can be quite hot for some programs (observed on some compression algorithms with ~90% of unaligned accesses). Move them to tsan_interface_inl.h to avoid the additional call and enable constant propagation. Also reorder the actual store and memory access handling for __sanitizer_unaligned_store callbacks to enable tail calling in MemoryAccess. Depends on D107282.

On lots of CPUs it finishes in ~2 secs. But with taskset -c 0-1 it runs for hundreds of seconds effectively spinning in the barrier in the sleep loop. We now have the handy futex API in sanitizer_common. Use it instead of the passive spin loop. It makes the test run only faster with taskset -c 0-1, it runs for ~1.5 secs, while with full parallelism it still runs for ~2 secs (but consumes less CPU time). Depends on D107131.
