| 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... |
