[PATCH] D60093: [LoopPredication] Allow predication of loop invariant computations

[Philip Reames via Phabricator via llvm-commits]

reames updated this revision to Diff 195189.
reames added a comment.

Remove the invariant expression complexity, and the SCEV loop disposition case.  I'm still hoping to sink that into SCEV, but handling the simple case is straight forward and I'd like to get at least that in.  The SCEV patch turns out to be a bit more complex than I'd originally expected, so I need to take a step back and revaluate that approach.

Still working on the builder usage.  Likely to update again, but I wanted to keep the snapshot of the progress.
