--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Ryan Lortie from comment #2) > Why is this violation of standards treated in a special way? Because it slows down things way too much. Much better is just to use -msse2 -mfpmath=sse if you really need to use 32-bit programs and have at least SSE2 capable CPU, i387 floating point stack has tons of issues.
