I have been compiling with -mfpmath=387 for a while. It does work, but also results in a significant slowdown in performance. Still useable, but noticeably slower. Sometime, i'd like to figure out if this is gcc bug, or (eek) a processor bug. I compiled a couple quick tests of my own a while back comparing -mfpmath=sse to -mfpmath=387. The problem occurs with divisions. off-by-one in certain cases, but i didn't get much further than that. > -- > rephorm > > > ------------------------------------------------------- > This SF.Net email is sponsored by the JBoss Inc.
