Here's  for SSE3. As for including CMOV to "Cpuflags:", I don't see 
anything in cpudetect.c for a "hasCMOV" or anything.

CPUflags:  MMX: 1 MMX2: 1 3DNow: 0 3DNowExt: 0 SSE: 1 SSE2: 1 SSE3: 1 
SSSE3: 1 SSE4: 1 SSE4.2: 1 AVX: 1
Compiled for x86 CPU with extensions: MMX MMX2 SSE SSE2 SSE3 SSSE3 SSE4 
SSE4.2 AVX CMOV
