--- Comment #35 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-01-10 11:37:08 UTC ---
For config/posix it is not that easy, because you can't assume that atomics are
available.  You'd need to guard it with #ifdef HAVE_SYNC_BUILTINS and do
something else (nothing?) otherwise.  Those targets don't support tsan
anyway...
