10#
11# aes-*-cbc benchmarks are improved by >70% [compared to gcc 3.3.2 on
12# Opteron 240 CPU] plus all the bells-n-whistles from 32-bit version
13# [you'll notice a lot of resemblance], such as compressed S-boxes
14# in little-endian byte order, prefetch of these tables in CBC mode,
15# as well as avoiding L1 cache aliasing between stack frame and key
16# schedule and already mentioned tables, compressed Td4...
17#
18# Performance in number of cycles per processed byte for 128-bit key:
19#
20# ECB CBC encrypt
21# AMD64 13.7 13.0(*)
22# EM64T 20.2 18.6(*)
23#
24# (*) CBC benchmarks are better than ECB thanks to custom ABI used
25# by the private block encryption function.
