From 29a4dd92b7066e42de5fa2ac25b99c48b147ac78 Mon Sep 17 00:00:00 2001 From: Tobias Grosser Date: Sat, 2 Jul 2016 07:58:13 +0000 Subject: [PATCH] CodegenCleanup: Drop CFLAA pass from codegen cleanup sequence Since r274197 -polly-position=before-vectorizer caused various LNT failures for example in SingleSource/Benchmarks/Linpack. These failures seem to only occur when the CFLAA pass is scheduled in our codegen-cleanup passes, which suggests that the way we call this AA pass is somehow problematic. As this pass is not of high importance, we drop the pass for now to prevent these failures from happening. At a later point, we might investigate more in-depth why this specific usage scenario caused correctness issues. llvm-svn: 274427 --- polly/lib/CodeGen/CodegenCleanup.cpp | 1 - 1 file changed, 1 deletion(-) diff --git a/polly/lib/CodeGen/CodegenCleanup.cpp b/polly/lib/CodeGen/CodegenCleanup.cpp index 44a12c4e6aab..8e8b7c43bf3c 100644 --- a/polly/lib/CodeGen/CodegenCleanup.cpp +++ b/polly/lib/CodeGen/CodegenCleanup.cpp @@ -49,7 +49,6 @@ public: // TODO: How to make parent passes discoverable? // TODO: Should be sensitive to compiler options in PassManagerBuilder, to // which wo do not have access here. - FPM->add(createCFLAAWrapperPass()); FPM->add(createScopedNoAliasAAWrapperPass()); FPM->add(createTypeBasedAAWrapperPass()); FPM->add(createAAResultsWrapperPass());
