# Initial support for Fujitsu SPARC64 X/X+ comprises minimally
# required key setup and single-block procedures.
#
# April 2016
#
# Add "teaser" CBC and CTR mode-specific subroutines. "Teaser" means
# that parallelizable nature of CBC decrypt and CTR is not utilized
# yet. CBC encrypt on the other hand is as good as it can possibly
# get processing one byte in 4.1 cycles with 128-bit key on SPARC64 X.
# This is ~6x faster than pure software implementation...
#
# July 2016
#
# Switch from faligndata to fshiftorx, which allows to omit alignaddr
# instructions and improve single-block and short-input performance
# with misaligned data.
