Yep, I have no prolem doing the heavy part just at a specified point. (it usually converges quickly, but there are no guarantees) In fact one of reasons why I fully separated the context lattice operations from ipa-prop is that I think it may make sense to have special purpose intraprocedural pass to do the propagation probably twice - once in early passes and once in late. Did not get into that for GCC 5 though.
