Run your IR testcase with "llc -stop-before=unpack-mi-bundles"; that should give you MIR in the form the second run of Thumb2SizeReduction will see it.



================
Comment at: lib/Target/ARM/Thumb2SizeReduction.cpp:924
+    MO.setIsKill(false);
+    MO.setIsDef(true);
+    MIB.add(MO);
----------------
Maybe also `setIsDead(true)`?  Probably doesn't make much difference this late, but probably better to be consistent.
