[PATCH] D87585: [AMDGPU] Dynamically clear renamable to avoid constant bus errors

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

Do you have any stats on how many more copies get propagated, and how many instructions that actually saves in the final ISA? I have a feeling that SIFoldOperands currently catches a lot of the cases that MachineCopyProp misses.
