+# SHA1 block procedure for s390x.
+
+# April 2007.
+#
+# Performance is >30% better than gcc 3.3 generated code. But the real
+# twist is that SHA1 hardware support is detected and utilized. In
+# which case performance can reach further >4.5x for larger chunks.
+
+# January 2009.
+#
+# Optimize Xupdate for amount of memory references and reschedule
+# instructions to favour dual-issue z10 pipeline. On z10 hardware is
+# "only" ~2.3x faster than software.
