+// Apple A7	1.97		10.5 (+33%)	6.73 (-1%(**))
+// Cortex-A53	2.38		15.5 (+115%)	10.0 (+150%(***))

+// Mongoose	2.36		13.0 (+50%)	8.36 (+33%)
+//
+// (*)	Software SHA256 results are of lesser relevance, presented
+//	mostly for informational purposes.
+// (**)	The result is a trade-off: it's possible to improve it by
+//	10% (or by 1 cycle per round), but at the cost of 20% loss
+//	on Cortex-A53 (or by 4 cycles per round).
+// (***)	Super-impressive coefficients over gcc-generated code are
+//	indication of some compiler "pathology", most notably code
+//	generated with -mgeneral-regs-only is significanty faster
+//	and the gap is only 40-90%.
+//
+// October 2016.
+//
+// Originally it was reckoned that it makes no sense to implement NEON
+// version of SHA256 for 64-bit processors. This is because performance
+// improvement on most wide-spread Cortex-A5x processors was observed
+// to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+// observed that 32-bit NEON SHA256 performs significantly better than
+// 64-bit scalar version on *some* of the more recent processors. As
+// result 64-bit NEON version of SHA256 was added to provide best
+// all-round performance. For example it executes ~30% faster on X-Gene
+// and Mongoose. [For reference, NEON version of SHA512 is bound to
+// deliver much less improvement, likely *negative* on Cortex-A5x.
+// Which is why NEON support is limited to SHA256.]

+// SHA256/512 for ARMv8.
+//
+// Performance in cycles per processed byte and improvement coefficient
+// over code generated with "default" compiler:
+//
+//		SHA256-hw	SHA256(*)	SHA512
+// Apple A7	1.97		10.5 (+33%)	6.73 (-1%(**))
+// Cortex-A53	2.38		15.5 (+115%)	10.0 (+150%(***))
+// Cortex-A57	2.31		11.6 (+86%)	7.51 (+260%(***))
+// Denver	2.01		10.5 (+26%)	6.70 (+8%)
+// X-Gene			20.0 (+100%)	12.8 (+300%(***))
+// Mongoose	2.36		13.0 (+50%)	8.36 (+33%)
+//
+// (*)	Software SHA256 results are of lesser relevance, presented
+//	mostly for informational purposes.
+// (**)	The result is a trade-off: it's possible to improve it by
+//	10% (or by 1 cycle per round), but at the cost of 20% loss
+//	on Cortex-A53 (or by 4 cycles per round).
+// (***)	Super-impressive coefficients over gcc-generated code are
+//	indication of some compiler "pathology", most notably code
+//	generated with -mgeneral-regs-only is significanty faster
+//	and the gap is only 40-90%.
+//
+// October 2016.
+//
+// Originally it was reckoned that it makes no sense to implement NEON
+// version of SHA256 for 64-bit processors. This is because performance
+// improvement on most wide-spread Cortex-A5x processors was observed
+// to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+// observed that 32-bit NEON SHA256 performs significantly better than
+// 64-bit scalar version on *some* of the more recent processors. As
+// result 64-bit NEON version of SHA256 was added to provide best
+// all-round performance. For example it executes ~30% faster on X-Gene
+// and Mongoose. [For reference, NEON version of SHA512 is bound to
+// deliver much less improvement, likely *negative* on Cortex-A5x.
+// Which is why NEON support is limited to SHA256.]
