# 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...
18
# Performance in number of cycles per processed byte for 128-bit key:
24
# (*) CBC benchmarks are better than ECB thanks to custom ABI used
25
# by the private block encryption function.
27
$verticalspin=1; # unlike 32-bit version $verticalspin performs
28
# ~15% better on both AMD and Intel cores
