# Version 2.1.
#
# aes-*-cbc benchmarks are improved by >70% [compared to gcc 3.3.2 on
# Opteron 240 CPU] plus all the bells-n-whistles from 32-bit version
# [you'll notice a lot of resemblance], such as compressed S-boxes
# in little-endian byte order, prefetch of these tables in CBC mode,
# as well as avoiding L1 cache aliasing between stack frame and key
# schedule and already mentioned tables, compressed Td4...
#
# Performance in number of cycles per processed byte for 128-bit key:
#
#		ECB encrypt	ECB decrypt	CBC large chunk
# AMD64		33		43		13.0
# EM64T		38		56		18.6(*)
# Core 2	30		42		14.5(*)
# Atom		65		86		32.1(*)
