================
Comment at: lib/Target/ARM/ARMISelDAGToDAG.cpp:3299
+              Replacement[] = {Res, GlueOut};
+      Select(RHS.getNode());
+      CurDAG->ReplaceAllUsesWith(N, Replacement);
----------------
Do you actually need to call Select() explicitly here?  Instruction selection should pick it up automatically, I think.
