-# ====================================================================
-# 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/.
-# ====================================================================
-
-# I let hardware handle unaligned input, except on page boundaries
-# (see below for details). Otherwise straightforward implementation
-# with X vector in register bank. The module is big-endian [which is
-# not big deal as there're no little-endian targets left around].

-# sha256 | sha512

-#
-# (*) 64-bit code in 32-bit application context, which actually is
-# on TODO list. It should be noted that for safe deployment in
-# 32-bit *mutli-threaded* context asyncronous signals should be
-# blocked upon entry to SHA512 block routine. This is because
-# 32-bit signaling procedure invalidates upper halves of GPRs.
-# Context switch procedure preserves them, but not signaling:-(
-
-# Second version is true multi-thread safe. Trouble with the original
-# version was that it was using thread local storage pointer register.
-# Well, it scrupulously preserved it, but the problem would arise the
-# moment asynchronous signal was delivered and signal handler would
-# dereference the TLS pointer. While it's never the case in openssl
-# application or test suite, we have to respect this scenario and not
-# use TLS pointer register. Alternative would be to require caller to
-# block signals prior calling this routine. For the record, in 32-bit
-# context R2 serves as TLS pointer, while in 64-bit context - R13.
