[PATCH] D48102: Improve handling of COPY instructions with identical value numbers

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

We shouldn't really be calling joinCopy with something that is not a COPY, but I guess it's a minor issue.  Please replace the getOpcode() == ... with isImplicitDef(), and it should be fine.
