--- Comment #5 from Jeffrey A. Law <law at redhat dot com> ---
Where do you think we'd want that on-demand VRP?  I've got a tree here which
splits up tree-vrp.c dramatically.  The net result is I've got an embeddable
range analysis engine that's easy to wire into a dominator walker.

Alternately we'll have to wait for Andrew's work to land.
