Performance wise, there is very little change,
I measure it slightly faster for slog 3 & 4 (~+2%)
but neutral or very slightly negative for slot 5 & 6 (< 1 %)
on both
gcc
andclang
.It feels like an okay side effect
(we want to improve speed more for faster modes).
But the real goal was to reduce the amount of intrinsic code.
This approach could not be easily extended to
NEON
because the current implementation is significantly different between the 16, 32, and 64 entries.
