2022-02-15sanitizer: Use glibc _thread_db_sizeof_pthread symbol if presentJakub Jelinek1-5/+16
I've cherry-picked following fix from llvm-project. Recent glibcs have _thread_db_sizeof_pthread symbol variable which contains the size of struct pthread, so that sanitizers don't need to guess that and risk that it will change again. 2022-02-15 Jakub Jelinek <jakub@redhat.com> * sanitizer_common/sanitizer_linux_libcdep.cpp: Cherry-pick llvm-project revision ef14b78d9a144ba81ba02083fe21eb286a88732b.

So what is happening is DIST_SUBDIRS contains the conditional directories which is wrong, so we need to force DIST_SUBDIRS to be the same as SUBDIRS as recommened by the automake manual. OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.

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. Reviewed By: vitalybuka, melver commit 97795be22f634667ce7a022398c59ccc9f7440eb Author: Dmitry Vyukov <dvyukov@google.com> Date: Fri Jul 30 08:35:11 2021 +0200 tsan: optimize test-only barrier The updated lots_of_threads.c test with 300 threads started running for too long on machines with low hardware parallelism (e.g. taskset -c 0-1). 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.
