It's certainly not rejected. This looks good. I just want to give it
adequate attention to understand it before merging and be confident
that it's keeping or improving performance on most/all archs not just
a couple mainstream ones. When I first saw it I was worried the
popcount thing would be a problem and only fast on archs with native
popcounts, but I saw that you're not even using any native popcount
just portable arithmetic so that seems like a non-issue.
If anyone else has an opportunity to test performance on other archs
and post results I'd love to see them.
I don't expect to get to looking at this in depth until rolling a
release, but I am actively trying to do that again now.
Thanks for working on this and for pinging about it again!
