The -msse and -mmmx options are supposed to only allow using the mmx registers in inline assembly, or using the intrinsics, and not to authorize gcc to use these instructions. (Note that this is inconsistent with -msse2 which apparently does cause gcc to emit SSE2 instructions) So, I think in the best of all possible worlds, we would use -mmmx and -msse to announce that we have code which uses them, but still expect gcc to otherwise compile pre-P3 usable code. -Billy -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
