  12 # aes-*-cbc benchmarks are improved by >70% [compared to gcc 3.3.2 on
  13 # Opteron 240 CPU] plus all the bells-n-whistles from 32-bit version
  14 # [you'll notice a lot of resemblance], such as compressed S-boxes
  15 # in little-endian byte order, prefetch of these tables in CBC mode,
  16 # as well as avoiding L1 cache aliasing between stack frame and key
  17 # schedule and already mentioned tables, compressed Td4...
  18 #
  19 # Performance in number of cycles per processed byte for 128-bit key:
  20 #
  21 #               ECB encrypt     ECB decrypt     CBC large chunk
