#ifndef NO_WARN_X86_INTRINSICS
/* 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.  */
