[PATCH] D156692: [RISCV] Scalarize binop followed by extractelement to W instruction on RV64

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

It's not clear to me this should be restricted to i64 and i32 either. An i16 or i8 `add` for example doesn't require any extra code unless the result needs to be sign/zero extended.
