[PATCH] D147378: [LV] Replace symbolic stride with const in LV

[Philip Reames via Phabricator via llvm-commits]

This seems like it's duplicating information already available in PredicatedScalarEvolution.

You can see my D147750 <https://reviews.llvm.org/D147750> for one example where PSE solves a related problem.  I suspect we should probably be phrasing this one in terms of constant folding and instsimplify where the constants might come from PSE.  Maybe this doesn't work out, but I'd suggest trying that before adding additional complexity here.
