Actually, my assembler doesn't seem to support SSE instructions.
How do we test for it?
Just try to compile this line:
maskmovq %mm0, %mm0
Like we're doing for the MMX test.
It'll test for the presence of MMX+ (3DNow!2 or SSE).
FYI, you need GAS 2.11.90+. 2.10.90 (shipped with RH 7.0) can't compile it.
