From f69162486b7911adf39a4f2884957c2720c65487 Mon Sep 17 00:00:00 2001 From: Johannes Doerfert Date: Mon, 15 Feb 2016 12:21:11 +0000 Subject: [PATCH] Revert "[FIX] Hoist accesses if AA stated they are invariant" This reverts commit 98efa006c96ac981c00d2e386ec1102bce9f549a. The fix was broken since we do not use AA in the ScopDetection anymore to check for invariant accesses. llvm-svn: 260884 --- polly/lib/Analysis/ScopInfo.cpp | 6 --- polly/test/Isl/CodeGen/hoisting_1.ll | 68 ---------------------------- polly/test/Isl/CodeGen/hoisting_2.ll | 87 ------------------------------------ 3 files changed, 161 deletions(-) delete mode 100644 polly/test/Isl/CodeGen/hoisting_1.ll delete mode 100644 polly/test/Isl/CodeGen/hoisting_2.ll diff --git a/polly/lib/Analysis/ScopInfo.cpp b/polly/lib/Analysis/ScopInfo.cpp index 2c05b10..8c33779 100644 --- a/polly/lib/Analysis/ScopInfo.cpp +++ b/polly/lib/Analysis/ScopInfo.cpp @@ -2997,12 +2997,6 @@ bool Scop::isHoistableAccess(MemoryAccess *Access, return false;
