[David Li via Phabricator via llvm-commits]

================
Comment at: lib/Transforms/Instrumentation/IndirectCallPromotion.cpp:592
 
-  insertCallRetPHI(Inst, NewInst, DirectCallee);
+  if (!Inst->use_empty())
+    insertCallRetPHI(Inst, NewInst, DirectCallee);
----------------
may be wrap this check inside the function just as other checks?
