Jingyue Wu f182c81444 [NaryReassociate] run NaryReassociate iteratively ... Summary: An alternative is to use a worklist approach. However, that approach would break the traversing order so that we couldn't lookup SeenExprs efficiently. I don't see a clear winner here, so I picked the easier approach. Along with two minor improvements: 1. preserves ScalarEvolution by forgetting instructions replaced 2. removes dead code locally avoiding the need of running DCE afterwards Test Plan: add to slsr-add.ll a test that requires multiple iterations Reviewers: broune, dberlin, atrick, meheff Reviewed By: atrick Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D9058 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@235151 91177308-0d34-0410-b5e6-96231b3b80d8		2015-04-17 00:25:10 +00:00
