= `BOOST_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 `BOOST_HW_SIMD_X86` to test if those specific extensions have
been detected.
