[PATCH] D72423: [DemandedBits] Improve accuracy of Add propagator

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

@rrika Performing these kinds of tests on IR is both quite inefficient and unnecessary complex. It would be better to extract the code logic (which just operates on APInts) into a separate file, which will allow you to easily test it, and also share the logic with other places doing demanded bits analysis, such as InstCombine and SelectionDAG.
