------- Comment #8 from rguenth at gcc dot gnu dot org 2009-02-20 09:57 ------- Though __builtin_not_reached () can be used to implement __builtin_assume (), so it may be more generally useful. if (i > 0) __builtin_not_reached (); will make GCC assume that i <= 0 on the other edge (of course we'd have to preserve this until some point to take advantage of it).
