[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIAnnotateControlFlow.cpp:317
+  if (!isa<UndefValue>(Exec) && !isa<UnreachableInst>(FirstInsertionPt)) {
+    Instruction *ExecDef = dyn_cast<Instruction>(Exec);
+    BasicBlock *DefBB = ExecDef->getParent();
----------------
This should be a cast since it's unchecked
