There was a problem hiding this comment.
If doing a divui I wonder if we should also check that the divisor is positive. The AffineExpr constraint assumes signed division iirc, which is why we originally didn't include.
Of course crashing is far worse, so we don't want that to occur.

Thank you very much for the feedback. I did not consider the sign issue with AffineExpr before. I will try another fix. Thanks again. |
