[PATCH] D58238: [DebugInfo] MachineSink: Insert undef DBG_VALUEs when sinking instructions, try to forward copies

[Nikola Prica via Phabricator via llvm-commits]

NikolaPrica added inline comments.


================
Comment at: lib/CodeGen/MachineSink.cpp:788
+
+    if (MI.isCopy()) {
+      bool DoCopy = false;
----------------
TargetInstrInfo::isCopyInstr here? It should support pseudo COPY instruction and target specific register copy instructions.
