--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- BTW, the tsan.exp tests don't seem to be as cheap as was claimed during the patch submission, I'd prefer to at least throttle the torture options down to say -O0 and -O2 rather than so many different variants when the tests are really small and optimizations don't really affect them that much if at all.
