[@https://en.wikipedia.org/wiki/SSE4##SSE4A SSE4A] x86 extension.

Version number is the default BOOST_VERSION_NUMBER_AVAILABLE.
|
|
|
|
This extension is only available on particular CPUs. It does imply
|
|
SSE3, but it is not implied by extensions newer than SSE3. For example,
|
|
SSE4.1 does not imply it.
