31 makes explicit use of Intel intrinsics to powerpc64le.
32 It is the user's responsibility to determine if the results are
33 acceptable and make additional changes as necessary.
34 Note that much code that uses Intel intrinsics can be rewritten in
35 standard C or GNU C extensions, which are more portable and better
36 optimized across multiple targets. */
