================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:21382
+            // Test = X == 0.0
+            Test = DAG.getSetCC(DL, CCVT, Op, FPZero, ISD::SETEQ);
         }
----------------
Question here: do we miss to propagate the SDFlags for SETCC which might affect how we lower the select_cc ?
