[PATCH] tsan: automatically deflake flaky tests

[Dmitry Vyukov]

Looks good to me.

It does not handle the case when a single test expects several reports. I've found 2 such existing tests:
test/tsan/global_race.cc
test/tsan/inlined_memcpy_race.cc
But both of them just checking several independent things. So I guess if it becomes a problem, we can split them into several tests.

Do you have any idea how to implement %try? Because I don't.
