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

+
+# sha1_block for Thumb.
+#
+# January 2007.
+#
+# The code does not present direct interest to OpenSSL, because of low
+# performance. Its purpose is to establish _size_ benchmark. Pretty
+# useless one I must say, because 30% or 88 bytes larger ARMv4 code
+# [avialable on demand] is almost _twice_ as fast. It should also be
+# noted that in-lining of .Lcommon and .Lrotate improves performance
+# by over 40%, while code increases by only 10% or 32 bytes. But once
+# again, the goal was to establish _size_ benchmark, not performance.
