Thread sanitizer flag to turn off "Thread created by" sections of log #1031

Open olologin opened 5 years ago

Is it possible to turn off "Thread created by" sections for every report? In some situations thread pool is created only once for program run, and the place where each thread is created doesn't give us any useful info. For example when we use OMP, all threads in its pool are created only once and at the same place. And for every other omp cycle the same place will be reported.

It just floods log. It's not crucial of course, but such optional flag might be useful.

There is no such option at the moment.

I guess it would also be useful for GCD, TBB and all other tasking libraries. I wonder if it's possible to auto-detect such threads... @kubamracek do we want to skip thread creation stack for headless GCD threads?

@dvyukov we already do, see PrintThread in tsan_report.cc
