# Add 6x"horizontal" VX implementation. It's ~25% faster than IBM's
|
||||
# 4x"vertical" submission [on z13] and >3 faster than scalar code.
|
||||
# But to harness overheads revert to transliteration of VSX code path
|
||||
# from chacha-ppc module, which is also 4x"vertical", to handle inputs
|
||||
# not longer than 256 bytes.
