[PATCH] D64393: [AMDGPU] Fix DPP combiner check for exec modification

[Valery Pykhtin via Phabricator via llvm-commits]

vpykhtin added a comment.

Matt, I'm not against using scan limiter, just about aborting the scan after the last use.

Jay, I'm ok with your patch, just a note that the prt set can be avoided if we count the number of use instructions and use the count to limit the scan.
