Hi Michael,

it is not fully clear what this patch is about. I assume this is a WIP alternative to https://reviews.llvm.org/D33142. My current understanding is that https://reviews.llvm.org/D33142 is stable and this is still very much work in progress (also the patch in this submission seems broken). Not sure what you had in mind, but it seems we should go for https://reviews.llvm.org/D33142 and keep this discussing until until we figure out that they work well. Indeed, Indeed, I am worried about the O(N^3) complexity.
