--- Comment #5 from Peter Bergner <bergner at gcc dot gnu.org> --- (In reply to Segher Boessenkool from comment #4) > If N is a power of two optimising this to a/N is valid, but for other values > of N it is not (division is not the inverse of multiplication in C). It also > only works for unsigned of course. Isn't this valid for any N & M, such that M is a factor of N? Meaning, as long as N / M has no remainder, it seems like this should be ok. For example, N = 30 & M = 2 should be just as ok as the N = 32 & M = 2 case, correct?
