Thanks for your interest. This project didn't mention AMD CPU because I
have no experience about it[1]. Maybe we could select a better set of
compiler options from [2] ?
Currently there are three branches (although badly synchronized
currently) in the SIMDebian archive[3]. With some slight modification on
the forked dpkg we can also setup specific archives for e.g. NEON (arm),
VSX (ppc64el), and advanced AMD CPU microarchitectures.
SIMDebian only cares about packages that would benefit from bumped ISA.
So the archive will be small even if we support tens of baselines over
different architectures at the same time.
[1] I've never had an AMD CPU in my life.
