# Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL
|
|
# project. The module is, however, dual licensed under OpenSSL and
|
|
# CRYPTOGAMS licenses depending on where you obtain it. For further

# SHA256/512 block procedures for s390x.
|
|
|
|
# April 2007.
|
|
#
|
|
# sha256_block_data_order is reportedly >3 times faster than gcc 3.3
|
|
# generated code (must be a bug in compiler, as improvement is
|
|
# "pathologically" high, in particular in comparison to other SHA
|
|
# modules). But the real twist is that it detects if hardware support
|
|
# for SHA256 is available and in such case utilizes it. Then the
|
|
# performance can reach >6.5x of assembler one for larger chunks.
|
|
#
|
|
# sha512_block_data_order is ~70% faster than gcc 3.3 generated code.
|
|
|
|
# January 2009.
|
|
#
|
|
# Add support for hardware SHA512 and reschedule instructions to
|
|
# favour dual-issue z10 pipeline. Hardware SHA256/512 is ~4.7x faster
|
|
# than software.
