Frankly, nobody has written the divide emulation code yet, so we have no numbers; it’s in the pipeline, but the emulation team has mostly been worrying about FP. If you’d like to help then feel free to post candidate code for div, rem, and divRem for the various widths. Remember that either or both inputs can be NaR/None. I do not expect there to be a loop; simply unroll the whole thing.

That said, the emulation substitution occurs at the start of the specializer where we are still working with dataflows, so if there is any code that is part of a different flow than the divide then the code will overlap.
