--- Comment #4 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-06-06 10:30:12 UTC --- It doesn't make too much sense to profile (cold) noreturn functions. It's probably easiest to not do it (check we have an outgoing edge). Another testcase would be triggering the transform to a noreturn function (so technically a sort-of invalid testcase).
