--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> 2012-12-20 16:54:53 UTC --- "To use these values, you need to be able to jump to one. This is done with the computed goto statement1, goto *exp;." > Not sure how to implement this properly. Use either setjmp/longjmp or getcontext/setcontext/makecontext instead.
