[PATCH] D78388: [globalisel][cse] Merge debug locations when CSE'ing

[Daniel Sanders via Phabricator via llvm-commits]

dsanders added a comment.

I currently don't have an in-tree test case for this but it should be possible to construct one. Essentially it needs CSE enabled, and needs two instructions that need legalization and emit a common instruction during their legalizations with identical constraints (to avoid the copy) and have conflicting debug locations. I'll try to make an AArch64 test case when I get chance.
