[PATCH] D104394: [MachineCopyPropagation] Fix differences in code gen when compiling with -g

[Kai Luo via Phabricator via llvm-commits]

lkail added a comment.

There is a patch https://reviews.llvm.org/D98401 doing the same. As discussed in D98401 <https://reviews.llvm.org/D98401>, the register in `DBG_VALUE` should be also updated. I think backward mcp is missing tracking usage when `MO.isDebug()` like forward mcp does.
