goldstein.w.n added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:9972
+// fold (bswap (logic_op(bswap(x),y))) -> logic_op(x,bswap(y))
+// This helper function accept ISD::BSWAP and ISD::BITREVERSE in Opcode
+// parameter
----------------
There is no opcode parameter. Maybe 'bswap or bitreverse nodes'?
