17   makes explicit use of Intel intrinsics to powerp64/powerpc64le.

19   It is the user's responsibility to determine if the results are
20   acceptable and make additional changes as necessary.
21
22   Note that much code that uses Intel intrinsics can be rewritten in
23   standard C or GNU C extensions, which are more portable and better
24   optimized across multiple targets.  */
