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

-// (*) 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 significantly faster
-// and the gap is only 40-90%.

-// 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.]
