[PATCH] D106403: [RISCV] Avoid using x0,x0 vsetvli for vmv.x.s and vfmv.f.s unless we know the sew/lmul ratio is constant.

[Kito Cheng via Phabricator via llvm-commits]

kito-cheng added a comment.

Maybe `vsetivli zero, 0, *` rather than `vsetivli zero, 1, *`, so that we can tell it's a special mark and won't confused with other intrinsic use VL=1, and easier to identify & optimize that in future?
