afonso360 opened PR #4403 from aarch64-of-fix to main:

@yuyang-ok reported via zulip that i128 overflow tests were wrong.

It turns out that both the tests and the aarch64 codegen are wrong.

I've altered the implementation to match what LLVM produces, and added the interpreter to that test suite.

And on the current main it fails in a different test:

Failed test: run: %icmp_of_i128(1, 170141183460469231731687303715884105727) == true, actual: false
