I'd say you pretty much get that with -mfpmath=sse. The only reason anyone should ever use 387 is if binary compatibility with ancient pre-SSE pentiums/K6s is required. Otherwise, it's an ancient and creaky fp architecture that would be best obsoleted (which they finally did in x86_64 AFAIK.) Brian
