To get you started, I put this series through:
https://gitlab.com/xen-project/hardware/xen-staging/-/pipelines/3000384733
There's one Eclair failure on ARM.
Interestingly, it's not the failure I was expecting to see. I was
expecting it to complain about
+ uint32_t insns[2] = {
+ aarch64_insn_gen_nop(),
+ aarch64_insn_gen_nop(),
+ };
because of the order those function calls being undefined.
I was also expecting to see some failures due to arithmetic on pointers
of different types, but maybe we've not made those rules enforcing yet.
