[PATCH] D31403: [SDAG] Deal with deleted node in PromoteIntShiftOp

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: lib/CodeGen/SelectionDAG/DAGCombiner.cpp:1161
     if (!N0.getNode())
       return SDValue();
 
----------------
Is there any case where the promotion of N0 will affect N1? Wouldn't shift(N0, N0) do this?
