How can I diagnose the build errors? It builds fine locally, and when I go to https://travis-ci.com/github/gonum/gonum/jobs/516634472 all I see in logs is "Automatic restarts limited: Please try restarting this job later or contact support@travis-ci.com."

Don't worry about travis. I can do local arm64 builds if you want. We have nearly run out of build minutes there and they are not very responsive.

Thanks. I think ARM will have the same FP precision as Intel so no need to adjust the tolerances for unit tests?

I'll take a look. For the most part the precision is the same. The differences, when they happen, are in numerically unstable functions due to differences in operation ordering and the fact that the arm64 code generation emits FMA and FMS instructions when it can while the amd64 doesn't.
