From 75b1fb9b9e22f7f8f76c89982674761c734c390b Mon Sep 17 00:00:00 2001 From: James Molloy Date: Wed, 31 Aug 2016 11:01:41 +0000 Subject: [PATCH] Attempt to pacify buildbots after r280217 These clang tests check diagnostics from the backend by giving it an unvectorizable loop. This loop is now vectorized :/ Make it really unvectorizable by making it unprofitable to ifconvert. llvm-svn: 280220 --- clang/test/Misc/backend-optimization-failure-nodbg.cpp | 4 ++-- clang/test/Misc/backend-optimization-failure.cpp | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/clang/test/Misc/backend-optimization-failure-nodbg.cpp b/clang/test/Misc/backend-optimization-failure-nodbg.cpp index 1e847185..aba37de 100644 --- a/clang/test/Misc/backend-optimization-failure-nodbg.cpp +++ b/clang/test/Misc/backend-optimization-failure-nodbg.cpp @@ -4,7 +4,7 @@ // Test verifies optimization failures generated by the backend are handled // correctly by clang.
