-# ====================================================================
-# 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
-# details see http://www.openssl.org/~appro/cryptogams/.
-# ====================================================================
-
-# 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.
