Add more gcc compatibility names to clang's cpuid.h

Authored by dim on Jul 5 2016, 1:20 PM.



Some cpuid bit defines are named slightly different from how gcc's cpuid.h calls them.

Define a few more compatibility names to appease software built for gcc:

  • bit_PCLMUL alias of bit_PCLMULQDQ
  • bit_SSE4_1 alias of bit_SSE41
  • bit_SSE4_2 alias of bit_SSE42
  • bit_AES alias of bit_AESNI
  • bit_CMPXCHG8B alias of bit_CX8

While here, add the misssing 29th bit, bit_F16C.

Isn't this one also meant for gcc compat?

Well, we didn't have any clang-specific define, so might as well choose the same name that gcc has used?
