 [heading `MSGPACK_HW_SIMD_X86_AMD`]

 The SIMD extension for x86 (AMD) (*if detected*).
 Version number depends on the most recent detected extension.

 [note This predef includes every other x86 SIMD extensions and also has other
 more specific extensions (FMA4, XOP, SSE4a). You should use this predef
 instead of `MSGPACK_HW_SIMD_X86` to test if those specific extensions have
 been detected.]
