--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Also, because strlen_to_stridx is only useful if warn_stringop_truncation, I
think if it is turned into a pointer to hash_map, then it could be left NULL if
!warn_stringop_truncation, and all the strlen_to_stridx related stuff only
performed if strlen_to_stridx != NULL.
