[PATCH] D116397: [RISCV] Add an MIR pass to replace redundant sext.w instructions with copies.

[Kito Cheng via Phabricator via llvm-commits]

kito-cheng added a comment.

LGTM without copy prorogation improvement, copy prorogation might cause extra code gen issue, so I think that part could improve later with more investigation.
