-# 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.
