19# aes-*-cbc benchmarks are improved by >70% [compared to gcc 3.3.2 on
20# Opteron 240 CPU] plus all the bells-n-whistles from 32-bit version
21# [you'll notice a lot of resemblance], such as compressed S-boxes
22# in little-endian byte order, prefetch of these tables in CBC mode,
23# as well as avoiding L1 cache aliasing between stack frame and key
24# schedule and already mentioned tables, compressed Td4...
25#
26# Performance in number of cycles per processed byte for 128-bit key:
