[PATCH] D114202: [AMDGPU] Fix SIPostRABundler crash on null register used by dbg value

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIPostRABundler.cpp:93
                                           BitVector &UsedRegUnits) const {
+  if (MI.isDebugInstr())
+    return;
----------------
This allows all meta instructions in the bundle region. Should it skip all of them?
