> Thanks for sharing the patch! I added some comments inline. Reasoning about this manually seems a bit fragile and verbose so I was wondering if it might be possible to re-use the existing reasoning infrastructure we have in SCEV to do the heavy lifting. I put up a patch that use SCEV, but I might be missing something that would make this unfeasible: D148841 <https://reviews.llvm.org/D148841>

Cool, thanks! Yeah the SCEV approach is much better. Let me work on the tests so we can test all the different cases.
