# 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.]
