# aes-*-cbc benchmarks are improved by 50% [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-boxs
# and prefetch of these tables in CBC mode, as well as avoiding L1
# cache aliasing between stack frame and key schedule and already
# mentioned tables.
#
# ECB performance is 15.6 cycles per processed byte for 128-bit key.
