> Do you mean in general or in for SCEV?

Well, I guess there's a question in general, but here I'm more concerned specifically about SCEV: what other analysis can it use, what sort of data structures can we use for caching.  But maybe I'm looking too many steps ahead; I don't want to get in the way of an incremental improvement.
