--- Comment #2 from Drea Pinski <pinskia at gcc dot gnu.org> ---
So jump threading is doing what it should be doing. I think the problem is
ifcvt is not as agressive as it should be in some cases.
Right now moving over rtl optimization. Though Jeff and I have talked about
doing some ifcvt right before expansion.
There is a lot of changes should be done on the gimple level dealing with
ifcvt; some are match patterns should be delayed until late. Some are removing
those match patterns and only doing them during expansion; e.g. `a ? b : 0`.
(but that is not directly related to this one).
