19 # Initial support for Fujitsu SPARC64 X/X+ comprises minimally
20 # required key setup and single-block procedures.
24 # Add "teaser" CBC and CTR mode-specific subroutines. "Teaser" means
25 # that parallelizeable nature of CBC decrypt and CTR is not utilized
26 # yet. CBC encrypt on the other hand is as good as it can possibly
27 # get processing one byte in 4.1 cycles with 128-bit key on SPARC64 X.
28 # This is ~6x faster than pure software implementation...
32 # Switch from faligndata to fshiftorx, which allows to omit alignaddr
33 # instructions and improve single-block and short-input performance
34 # with misaligned data.
