-// (*)  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.]
