------- Comment #4 from michael dot meissner at amd dot com 2008-02-14 00:20 ------- In terms of shipping systems, no AMD system supports SSSE3 right now. As I understand it, the SSSE3 instructions were inbetween SSE3 and SSE4.1 on Intel systems, so -mno-sse3 should turn off SSSE3, but -mno-sse4a should not turn off SSSE3. Current shipping AMD systems do support SSE3.
