So for compare_case_labels we only ever have one label with
!CASE_LOW - which means you only run into the case that needs
!CASE_LOW && !CASE_LOW if comparing an element with itself, correct?
In this case (missing "same element" handling rather than symmetry
fixing) I'd prefer a
if (case1 == case2)
return 0;
So just to confirm - do the patches also contain same element
compare fixings?
Yes, that's a fix for same element. How about adding if + gcc_assert
that both cases can't be NULL otherwise?
