--- Comment #4 from Robin Dapp <rdapp at gcc dot gnu.org> --- > Would it be possible to skip such optimization/canonicalization, as Clang > already does? In practice, an exact match is sometimes essential for > programming specific hardware effectively. Could you share a code snippet or a specific problem you're trying to solve? The idea is that the compiler takes care of optimal vsetvl placement. It sounds as if you want to emit a particular SEW, LMUL (to be used by another instruction?) and not just compute the vector length?
