I also encountered a case whereephemeral values affect whether other variables are promoted, causingperformance issues. It may be a bug in LSR, but I didn't manage toreduce it yet. Anyhow, I believe it's in general not worth consideringephemeral values in LSR.Reviewers: atrick, hfinkelSubscribers: llvm-commitsDifferential Revision: http://reviews.llvm.org/D11115llvm-svn: 242011 List of files: /llvm-project-15.0.7/llvm/test/Transforms/LoopStrengthReduce/ephemeral.ll Mon, 13 Jul 2015 03:28:53 +0000 Jingyue Wu <jingyue@google.com>
