+# ====================================================================
+# 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/.
+# ====================================================================
+#
+# Eternal question is what's wrong with compiler generated code? The
+# trick is that it's possible to reduce the number of shifts required
+# to perform rotations by maintaining copy of 32-bit value in upper
+# bits of 64-bit register. Just follow mux2 and shrp instructions...
+# Performance under big-endian OS such as HP-UX is 179MBps*1GHz, which
+# is >50% better than HP C and >2x better than gcc.
