From 8529dd5ee10ba8e852c92cece4bef0c93206953d Mon Sep 17 00:00:00 2001 From: Sanjay Patel Date: Tue, 27 Feb 2018 18:33:24 +0000 Subject: [PATCH] [ARM] add loop vectorizer test based on 482.sphinx3 from SPEC2006; NFC This is a slight reduction of one of the benchmarks that suffered with D43079. Cost model changes should not cause this test to remain scalarized. llvm-svn: 326221 --- llvm/test/Transforms/LoopVectorize/ARM/sphinx.ll | 165 +++++++++++++++++++++++ 1 file changed, 165 insertions(+) create mode 100644 llvm/test/Transforms/LoopVectorize/ARM/sphinx.ll diff --git a/llvm/test/Transforms/LoopVectorize/ARM/sphinx.ll b/llvm/test/Transforms/LoopVectorize/ARM/sphinx.ll new file mode 100644 index 0000000..19ed23b --- /dev/null +++ b/llvm/test/Transforms/LoopVectorize/ARM/sphinx.ll @@ -0,0 +1,165 @@ +;
