+# ====================================================================
+# 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.
