This is the follow up patch for https://reviews.llvm.org/D86183 as we miss to delete the node if NegX == NegY, which has use after we create the node. ``` if (NegX && (CostX <= CostY)) { Cost = std::min(CostX, CostZ); RemoveDeadNode(NegY); return DAG.getNode(Opcode, DL, VT, NegX, Y, NegZ, Flags); #<-- NegY is used here if NegY == NegX. } ``` Reviewed By: spatel Differential Revision: https://reviews.llvm.org/D86689
