[PATCH] D69130: [RISCV] Implement the TargetLowering::getRegisterByName hook

[Sam Elliott via Phabricator via llvm-commits]

lenary added a comment.

Please can you test using this with the register named `fp`. This is another alternate name for `x8` (aka `s0`) which is supported in some places, and should be supported here. I'm not sure if `MatchRegisterAltName` will pick it up. I think `x8` is the only register with three names (the rest all only have two).
