| //
| // 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.]
