man gcc. as for the sse fp math... it (from memory) makes gcc use the sse
instruction set to do floating point math operations. this is likely a bad
thing as it 1. means using the "mmx unit" and swapping out of fp mode and thus
you have a cycle hit with an emms coming back in - as the fp ops are short and
not all over this isn't much worth it. i suspect there is some conversion
rounding cumulative error. but as i dont have an amd64 i cant tell you much
more than what i suspect. :)
