2017-01-07	tsan: Introducing a function to flush the shadow memory from third-party ↵	Dmitry Vyukov
	libraries As discussed with Dmitry (https://goo.gl/SA4izd), I would like to introduce a function to be called from a third-party library to flush the shadow memory. In particular, we ran some experiments with our tool Archer (an OpenMP data race detector based on Tsan, https://github.com/PRUNER/archer) and flushing the memory at the end of an outer parallel region, slightly increase the runtime overhead, but reduce the memory overhead of about 30%. This feature would come very handy in case of very large OpenMP applications that may cause an "out of memory" exception when checked with Tsan.

	This is required for Java support, as real PCs don't work for Java. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@236484 91177308-0d34-0410-b5e6-96231b3b80d8
2015-01-27	tsan: properly instrument unaligned accesses	Dmitry Vyukov
	If a memory access is unaligned, emit __tsan_unaligned_read/write callbacks instead of __tsan_read/write. Required to change semantics of __tsan_unaligned_read/write to not do the user memory. But since they were unused (other than through __sanitizer_unaligned_load/store) this is fine.

2012-05-10	[tsan] First commit of ThreadSanitizer (TSan) run-time library.	Kostya Serebryany
	Algorithm description: http://code.google.com/p/thread-sanitizer/wiki/ThreadSanitizerAlgorithm Status: The tool is known to work on large real-life applications, but still has quite a few rough edges. Nothing is guaranteed yet. The tool works on x86_64 Linux. Support for 64-bit MacOS 10.7+ is planned for late 2012. Support for 32-bit OSes is doable, but problematic and not yet planed. Further commits coming: - tests - makefiles - documentation - clang driver patch The code was previously developed at http://code.google.com/p/data-race-test/source/browse/trunk/v2/ by Dmitry Vyukov and Kostya Serebryany with contributions from Timur Iskhodzhanov, Alexander Potapenko, Alexey Samsonov and Evgeniy Stepanov. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@156542 91177308-0d34-0410-b5e6-96231b3b80d8
