-  MachineOperand::printIRSlotNumber(OS, MST.getLocalSlot(&V));
+  if (MST.getCurrentFunction())
+    MachineOperand::printIRSlotNumber(OS, MST.getLocalSlot(&V));
----------------
Can we make this:

```
int Slot = MST.getCurrentFunction() ? MST.getLocalSlot(&V) : -1;
MachineOperand::printIRSlotNumber(OS, Slot);
```

?

That way, `printIRSlotNumber` will print `<badref>` instead of `?`.
