Really interesting, thanks so much!
As an example this is what it says about our Python 3.4 build (using the
Intel compilers):
[samuel@snowy bin]$ ~/bin/analyze-x86 python3.4
Disassembling python3.4, please wait...
MMX: 126
SSE: 1943
MMXExt: 153
Enh 3DNow: 0
SSE2: 1293
SSE3: 572
SSSE3: 694
SSE4A: 0
SSE4.1: 9
SSE4.2: 34
AES: 0
AVX: 2
AVX2: 0
FMA: 0
FMA4: 0
This binary was found to contain the cpuid instruction.
This could mean that the application checks if an opcode is
supported before executing it, meaning it may work even if
these instructions are not supported on the host.
