Topic: ✔ `isub` on `I8`

I see that <https://docs.rs/cranelift/latest/cranelift/prelude/types/constant.I8.html> says

WARNING: arithmetic on 8bit integers is incomplete

I was about to use isub between two icmp results, rather than needing a bunch of selecting. Should I not to that, to avoid the arithmetic on I8?

That warning may be somewhat out of date; arithmetic on i8s should work now, and if anything doesn't, please feel free to file an issue!

Thanks! Glad to hear it.
