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...
