================
Comment at: llvm/lib/CodeGen/MachineBasicBlock.cpp:973
   // reach, even though the branch should get folded to fall through implicitly.
-  if (MachineFunction::iterator(TBB) == Fallthrough ||
-      MachineFunction::iterator(FBB) == Fallthrough)
+  if (AllowExplicitFT && (MachineFunction::iterator(TBB) == Fallthrough ||
+      MachineFunction::iterator(FBB) == Fallthrough))
