Comes down to upstream's assumption of AVX2 support on all amd64 arches and good ol' Bulldozer quirks. Closed.
The -mavx2 shouldn't be harmful, simde is is there to provide runtime support for missing instructions. But I believe simde is misdetecting something, e.g. -march=x86-64-v2 (or -v2 with -mavx which leaves it still missing avx2) is fine, but -march=bdver2 is not. Still need to look closer at this but issue is "probably" in simde rather than kitty. Meanwhile you can use -march=x86-64-v2 as a workaround.
I noted that on the upstream bug too, but actually seems to be because -march=bdver2 enables -mxop or something related (I was wondering what it enabled that my -march=native didn't, and xop came up). I'll check for another workaround, albeit issue is likely in simde rather than kitty.

Thankfully simde gives a lot of defines to control what it does, but ideally it should be looked at in simde itself upstream.
