17	# ====================================================================

19	# SHA256 performance improvement over compiler generated code varies
20	# from 40% for Sun C [32-bit build] to 70% for gcc [3.3, 64-bit
21	# build]. Just like in SHA1 module I aim to ensure scalability on
22	# UltraSPARC T1 by packing X[16] to 8 64-bit registers.
23
24	# SHA512 on pre-T1 UltraSPARC.
25	#
26	# Performance is >75% better than 64-bit code generated by Sun C and
27	# over 2x than 32-bit code. X[16] resides on stack, but access to it
28	# is scheduled for L2 latency and staged through 32 least significant
29	# bits of %l0-%l7. The latter is done to achieve 32-/64-bit ABI
30	# duality. Nevertheless it's ~40% faster than SHA256, which is pretty
31	# good [optimal coefficient is 50%].
32	#
33	# SHA512 on UltraSPARC T1.
34	#
35	# It's not any faster than 64-bit code generated by Sun C 5.8. This is
36	# because 64-bit code generator has the advantage of using 64-bit
37	# loads(*) to access X[16], which I consciously traded for 32-/64-bit
38	# ABI duality [as per above]. But it surpasses 32-bit Sun C generated
39	# code by 60%, not to mention that it doesn't suffer from severe decay
40	# when running 4 times physical cores threads and that it leaves gcc
41	# [3.4] behind by over 4x factor! If compared to SHA256, single thread
42	# performance is only 10% better, but overall throughput for maximum
43	# amount of threads for given CPU exceeds corresponding one of SHA256
44	# by 30% [again, optimal coefficient is 50%].
45	#
46	# (*) Unlike pre-T1 UltraSPARC loads on T1 are executed strictly
47	# in-order, i.e. load instruction has to complete prior next
48	# instruction in given thread is executed, even if the latter is
49	# not dependent on load result! This means that on T1 two 32-bit
50	# loads are always slower than one 64-bit load. Once again this
51	# is unlike pre-T1 UltraSPARC, where, if scheduled appropriately,
52	# 2x32-bit loads can be as fast as 1x64-bit ones.
53	#
54	# SPARC T4 SHA256/512 hardware achieves 3.17/2.01 cycles per byte,
55	# which is 9.3x/11.1x faster than software. Multi-process benchmark
56	# saturates at 11.5x single-process result on 8-core processor, or
57	# ~11/16GBps per 2.85GHz socket.
