Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-11-14 07:51:44 UTC --- Note that GCC doesn't perform any ASAN optimizations yet (if the same address is written or read several times in the same bb, it doesn't optimize away the tests). We plan to first switch to first expanding the shadow memory checks as simple builtins without control flow, performing optimizations on them and only later on (in fab pass?) to expand it to the longer sequences with control flow in them.
