# ppc_AES_[en|de]crypt perform at 18 cycles per byte processed with
# 128-bit key, which is ~40% better than 64-bit code generated by gcc
# 4.0. But these are not the ones currently used! Their "compact"
# counterparts are, for security reason. ppc_AES_encrypt_compact runs
# at 1/2 of ppc_AES_encrypt speed, while ppc_AES_decrypt_compact -
# at 1/3 of ppc_AES_decrypt.
# February 2010
#
# Rescheduling instructions to favour Power6 pipeline gave 10%
# performance improvement on the platform in question (and marginal
# improvement even on others). It should be noted that Power6 fails
# to process byte in 18 cycles, only in 23, because it fails to issue
# 4 load instructions in two cycles, only in 3. As result non-compact
# block subroutines are 25% slower than one would expect. Compact
# functions scale better, because they have pure computational part,
# which scales perfectly with clock frequency. To be specific
# ppc_AES_encrypt_compact operates at 42 cycles per byte, while
# ppc_AES_decrypt_compact - at 55 (in 64-bit build).
