# ====================================================================
# SHA256 performance improvement over compiler generated code varies
# from 40% for Sun C [32-bit build] to 70% for gcc [3.3, 64-bit
# build]. Just like in SHA1 module I aim to ensure scalability on
# UltraSPARC T1 by packing X[16] to 8 64-bit registers.
# SHA512 on pre-T1 UltraSPARC.
#
# Performance is >75% better than 64-bit code generated by Sun C and
# over 2x than 32-bit code. X[16] resides on stack, but access to it
# is scheduled for L2 latency and staged through 32 least significant
# bits of %l0-%l7. The latter is done to achieve 32-/64-bit ABI
# duality. Nevetheless it's ~40% faster than SHA256, which is pretty
# good [optimal coefficient is 50%].
#
# SHA512 on UltraSPARC T1.
#
# It's not any faster than 64-bit code generated by Sun C 5.8. This is
# because 64-bit code generator has the advantage of using 64-bit
# loads(*) to access X[16], which I consciously traded for 32-/64-bit
# ABI duality [as per above]. But it surpasses 32-bit Sun C generated
# code by 60%, not to mention that it doesn't suffer from severe decay
# when running 4 times physical cores threads and that it leaves gcc
# [3.4] behind by over 4x factor! If compared to SHA256, single thread
# performance is only 10% better, but overall throughput for maximum
# amount of threads for given CPU exceeds corresponding one of SHA256
# by 30% [again, optimal coefficient is 50%].
#
# (*) Unlike pre-T1 UltraSPARC loads on T1 are executed strictly
# in-order, i.e. load instruction has to complete prior next
# instruction in given thread is executed, even if the latter is
# not dependent on load result! This means that on T1 two 32-bit
# loads are always slower than one 64-bit load. Once again this
# is unlike pre-T1 UltraSPARC, where, if scheduled appropriately,
# 2x32-bit loads can be as fast as 1x64-bit ones.
#
# SPARC T4 SHA256/512 hardware achieves 3.17/2.01 cycles per byte,
# which is 9.3x/11.1x faster than software. Multi-process benchmark
# saturates at 11.5x single-process result on 8-core processor, or
# ~11/16GBps per 2.85GHz socket.
