Mehdi Amini dd38378605 Fix SLPVectorizer commutativity reordering ... The SLPVectorizer had a very crude way of trying to benefit from associativity: it tried to optimize for splat/broadcast or in order to have the same operator on the same side. This is benefitial to the cost model and allows more vectorization to occur. This patch improve the logic and make the detection optimal (locally, we don't look at the full tree but only at the immediate children). Should fix https://llvm.org/bugs/show_bug.cgi?id=25247 Reviewers: mzolotukhin Differential Revision: http://reviews.llvm.org/D13996 From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 252337		2015-11-06 20:17:51 +00:00
