--- Comment #11 from Martin Jambor <jamborm at gcc dot gnu.org> 2012-08-30 15:58:40 UTC --- The aggregate functions and their use in inlining/ipa-cp heuristics is in, at least with my PHI predicate computing patch which I re-submitted today we even get a predicate for known loop iterations for function init today. This means that even today the function in your app should be inlined much more likely. In order to propagate stuff without inlining, IPA-CP must be enhanced which is something I am still only working on.
