Same question to k8-sse3, opteron-sse3, athlon64-sse3. Please take a look at this link : http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html#i386-and-x86_002d64-Options As it is may be not a problem to have more aliases (not listed in gcc manuals), it sounds really bad idea to not have the same names as GCC. -- Best Wishes, Stefan Lambrev ICQ# 24134177
