-# ====================================================================
-# Written by Andy Polyakov <appro@openssl.org> 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/.
-# ====================================================================
-#
-# March 2010
-#
-# The module implements "4-bit" GCM GHASH function and underlying
-# single multiplication operation in GF(2^128). "4-bit" means that it
-# uses 256 bytes per-key table [+128 bytes shared table]. Even though
-# loops are aggressively modulo-scheduled in respect to references to
-# Htbl and Z.hi updates for 8 cycles per byte, measured performance is
-# ~12 cycles per processed byte on 21264 CPU. It seems to be a dynamic
-# scheduling "glitch," because uprofile(1) indicates uniform sample
-# distribution, as if all instruction bundles execute in 1.5 cycles.
-# Meaning that it could have been even faster, yet 12 cycles is ~60%
-# better than gcc-generated code and ~80% than code generated by vendor
-# compiler.
