------- Comment #110 from pepalogik at seznam dot cz 2008-06-12 14:14 ------- I used an old version of GCC documentation so I omitted some new processors with SSE: core2, k8-sse3, opteron-sse3, athlon64-sse3, amdfam10 and barcelona. I think you can use -march=pentium3 for all Intel's CPUs (of course, starting with P3). I'm unsure about AMD. (Maybe you know it better.)
