-# SHA512_Transform_SSE2.
-#
-# As the name suggests, this is an IA-32 SSE2 implementation of
-# SHA512_Transform. Motivating factor for the undertaken effort was that
-# SHA512 was observed to *consistently* perform *significantly* poorer
-# than SHA256 [2x and slower is common] on 32-bit platforms. On 64-bit
-# platforms on the other hand SHA512 tend to outperform SHA256 [~50%
-# seem to be common improvement factor]. All this is perfectly natural,
-# as SHA512 is a 64-bit algorithm. But isn't IA-32 SSE2 essentially
-# a 64-bit instruction set? Is it rich enough to implement SHA512?
-# If answer was "no," then you wouldn't have been reading this...
-#
-# Throughput performance in MBps (larger is better):
-#
-#		2.4GHz P4	1.4GHz AMD32	1.4GHz AMD64(*)
-# SHA256/gcc(*)	54		43		59
-# SHA512/gcc	17		23		92
-# SHA512/sse2	61(**)		57(**)
-# SHA512/icc	26		28
-# SHA256/icc(*)	65		54
-#
-# (*)	AMD64 and SHA256 numbers are presented mostly for amusement or
-#	reference purposes.
-# (**)	I.e. it gives ~2-3x speed-up if compared with compiler generated
-#	code. One can argue that hand-coded *non*-SSE2 implementation
-#	would perform better than compiler generated one as well, and
-#	that comparison is therefore not exactly fair. Well, as SHA512
-#	puts enormous pressure on IA-32 GP register bank, I reckon that
-#	hand-coded version wouldn't perform significantly better than
-#	one compiled with icc, ~20% perhaps... So that this code would
-#	still outperform it with distinguishing marginal. But feel free
-#	to prove me wrong:-)
