+   with a large offset that the assembler rejects.  Instead it should a
+   PLWZ/CMPWI combination.
+
+   Originally, the code was dying because the fusion load + compare -1/0/1
+   patterns did not handle the possibility that the load might be prefixed.
+   The -fstack-protector option is needed to show the bug.  */
