# ====================================================================

# 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 procedure for Alpha.



# On 21264 performance is 33% better than code generated by vendor

# compiler, and 75% better than GCC [3.4]. Implementation features

# vectorized byte swap, but not Xupdate.

# Performance improvement is 30% on unaligned input. The "secret" is

# to deploy lwl/lwr pair to load unaligned input. One could have

# compatible subroutine. There is room for minor optimization on

# little-endian platforms...

# The code is somewhat IRIX-centric, i.e. is likely to require minor
