Not sure whether the decision has already been done but I'll put my two cents here.
You have covered all the tradeoffs. Since in most cases, the divisor is positive, I believe the important move was to add one of floordiv or euclideandiv (which you are doing now). The difference between floordiv and euclideandiv will not have drastic effect on how much we can simplify the code. Nevertheless, IMHO, we should choose Euclidean for the followin reasons: 1) it's more important to care about ease/strength of simplification and analysis and less about familiarity. 2) familiarity is a subjective matter and it depends on the audience. The audience of this operator (and in general Halide IR) are mostly people who are developing the core compiler. In the long run, this audience cares mostly about what's more powerful in terms of analysis, simplification, and interoperability with other libs and I expect people to become familiar (if they are not already) with euclideandiv very quickly. -- You are receiving this because you are subscribed to this thread.
