5 ; Cfunc and Dfunc differ only in that one returns i64, the other a pointer, and
6 ; both return undef. They should be merged. Note undef cannot be merged with
7 ; anything else, because this implies the ordering will be inconsistent (i.e.
8 ; -1 == undef and undef == 1, but -1 < 1, so we must have undef != <any int>).
