[Dávid Bolvanský via Phabricator via llvm-commits]

================
Comment at: llvm/lib/Transforms/InstCombine/InstructionCombining.cpp:782
+      SI = Builder.CreateSelect(A, Builder.CreateBinOp(Opcode, B, E), V1);
+  } else if (LHSIsSelect) {
+    // (A ? B : C) op Y -> A ? (B op Y) : (C op Y)
----------------
Can you simplify lines 782-808? Almost same code in both branches..
