111170 + * This plugin recomputes expressions of function arguments marked by a size_overflow attribute
111171 + * with double integer precision (DImode/TImode for 32/64 bit integer types).
111172 + * The recomputed argument is checked against TYPE_MAX and an event is logged on overflow and the triggering process is killed.
111173 + *
