[PATCH] D152845: [RISCV][InsertVSETVLI] Treat vmv.v.i as-if it were vmv.s.x when VL=1, and inactive lanes are undefined

[Luke Lau via Phabricator via llvm-commits]

luke added a comment.

Is it possible to move this into getDemanded so that it’s also used by the bottom-to-top pass in phase 3? Otherwise this won’t catch cases that are at the start of blocks with no successors, e.g. the vmv.v.i is the first instruction of the function.
