-# 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/.

-
-# SHA512 block procedure for ARMv4. September 2007.
-
-# This code is ~4.5 (four and a half) times faster than code generated
-# by gcc 3.4 and it spends ~72 clock cycles per byte [on single-issue
-# Xscale PXA250 core].
-#
-# July 2010.
-#
-# Rescheduling for dual-issue pipeline resulted in 6% improvement on
-# Cortex A8 core and ~40 cycles per processed byte.
-
-# February 2011.
-#
-# Profiler-assisted and platform-specific optimization resulted in 7%
-# improvement on Coxtex A8 core and ~38 cycles per byte.
-
-# March 2011.
-#
-# Add NEON implementation. On Cortex A8 it was measured to process
-# one byte in 25.5 cycles or 47% faster than integer-only code.
-
-# Byte order [in]dependence. =========================================
-#
-# Originally caller was expected to maintain specific *dword* order in
-# h[0-7], namely with most significant dword at *lower* address, which
-# was reflected in below two parameters as 0 and 4. Now caller is
-# expected to maintain native byte order for whole 64-bit values.
