--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Daniel Gutson from comment #3) > OK. That was my second suggested alternative. > BTW I didn't see __builtin_trap documented as noreturn in the documentation. Depends on the reading of __builtin_trap documentation. My reading says it does not return. "This function causes the program to exit abnormally. GCC implements this function by using a target-dependent mechanism (such as intentionally executing an illegal instruction) or by calling abort." Since the documentation talks about calling abort, I would assume __built_trap should be treated almost the same as calling abort.
