Open Issues in the TSAN Runtime

[Bernd Edlinger]

Hi Jakub,

I am asking if we plan to merge the TSAN runtime from the LLVM tree soon, or if it is better to cherry pick
specific changes from there.

I am especially interested in fixing these two issues, but there may be other important improvements too:


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64350 : TSAN fails after stress-testing for a while

was fixed by

http://llvm.org/viewvc/llvm-project/compiler-rt/trunk/lib/sanitizer_common/sanitizer_deadlock_detector.h?r1=224518&r2=224517&pathrev=224518
http://llvm.org/viewvc/llvm-project/compiler-rt/trunk/lib/sanitizer_common/sanitizer_deadlock_detector.h?r1=224519&r2=224518&pathrev=224519



https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63251 : tsan: corrupted shadow stack

was fixed by

Thanks
