Dmitry Vyukov 0c40a5600c tsan: run output tests in parallel 
llvm-svn: 164997
 2012-10-02 11:51:40 +00:00
Evgeniy Stepanov f7f616ba66 Quick fix data/bss detection in TSan. 
The old way breaks when a module's bss is adjacent to the [heap] vm area.
Both ways are not very reliable, though.

Alexey Samsonov 351d486df0 [TSan] one more attempt to fix sleep_sync test: call sleep in the spawned thread so that sleep-synchronization will be detected even if child thread is started late. 
llvm-svn: 164488
 2012-09-24 13:35:46 +00:00

Kostya Serebryany 4ad375f0a9 [tsan] First commit of ThreadSanitizer (TSan) run-time library. 
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.
