Hi Michael and others, Scrappie looks like a candidate where we can use the simde trick. I tried doing a patch, and it works on amd64 machine, but not on an arm64 porter box :/ (with issues with __v4sf)
And I'm not sure how to fix this, and hence this is a humble request to please take a look - and any help/hints would be really great. My patch is pushed to salsa[1] I'm also sorry if these pings are somehow irritating, since I need help admittedly.
