> We need to pick the same semantics for all CPUs. I worry about whether
the best-performing semantic differs... at least it might differ on 32-bit
vs. 64-bit for us
The semantics will be the same for all CPUs. The proposed change can't
make performance any ''worse'', but it can improve performance on some
CPUs where the native division semantics matches what we expose in
Haskell.
