Did you test x86_64 with -march=native (or with -mfma) or just -O3? The reason why I am asking is aarch64 includes FMA by default while x86_64 does not. Most recent x86_64 includes an FMA instruction but since the base ISA does not include it, it is not enabled by default. I am suspect the aarch64 "excessive exceeding the threshold for errors" are all caused by the more use of FMA rather than anything else.
Aah, I forgot to include that tidbit, because its readily apparent from the full logs - I compiled with *just* -O3.
