--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> ---
Ok, so the reason is following:
- in case of -fsanitise=undef, we don't have an option match as so we search in
all possible options and their values, that's why have a match
- in case of -fsanitize=undef, we first match -fsanitize and then
get_closest_sanitizer_option is called; the function only compares option
values and we don't have a match for 'undefined' as 'undef' does not reach
distance threshold.
It's a limitation, but having low priority to me.
