If you do add these using either gcc inline assembly or intrinsics, please
make sure to fence the changes with a macro and provide implementations for
compilers that don't support those features. Some compilers, Cray's CCE for
instance, do set __GNUC__ so that they can use glibc, but don't support all
gcc features.

Thanks.
