New Revision: 255185
URL: http://svnweb.freebsd.org/changeset/base/255185
Log:
add support to gcc for AES and PCLMUL intrinsics... This addes the
-maes option, but not the -mpclmul option as I ran out of bits in
the 32 bit flags field... You can -D__PCLMUL__ to get this, but it
won't be compatible w/ clang and modern gcc...
