[PATCH] D51794: AMDGPU: Don't error on calls to null or undef

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

HCC had a bug recently that was producing calls to under. I assume a call to null would appear for a pure virtual call. They are undefined to execute, but they could appear in dead code that is never reached so it’s not an error to have them exist
