[PATCH] Divergence analysis for GPU programs

[Daniel Berlin]

+fernando, who wrote the paper on divergence analysis you cite (and some
follow-ons, i believe), and had an LLVM implementation of it.
It may make sense for him to look over the algorithm itself.


(Note that looking at your paper, i'll point out their is a version that
handles affine constraints, etc at
https://hal.inria.fr/hal-00650235v1/document.  I have no opinion on whether
it's better for your usecases, but I know it can be made as fast as your
current algorithm :P)
