[PATCH] D89187: [AMDGPU] Minimize number of s_mov generated by copyPhysReg

[Nicolai Hähnle via Phabricator via llvm-commits]

nhaehnle added a comment.

How about splitting this change into two parts? Limit this change to generating mixes of 64- and 32-bit moves, and then separately consider what to do about those moves of registers where subregisters are overwritten immediately.
