[PATCH] D92286: [RISCV] Form GORCI from (or (rotl/rotr X, Bitwidth/2), X).

[Fraser Cormack via Phabricator via llvm-commits]

frasercrmck added a comment.

It might be worth mentioning somewhere (the commit message?) why this isn't done by matching `(rotl/rotr X, Bitwidth/2)` as `GREVI` and then matching `GORCI` through that. Presumably we'd like to match `GREVI` of `rotl/rotr` too, for instance?
