/* This header is distributed to simplify porting x86_64 code that
makes explicit use of Intel intrinsics to powerp64/powerpc64le.
It is the user's responsibility to determine if the results are
acceptable and make additional changes as necessary.
Note that much code that uses Intel intrinsics can be rewritten in
standard C or GNU C extensions, which are more portable and better
optimized across multiple targets. */
