From d6d9ccca38f47594a61a5636b58dc99c6d2ec0ea Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Thu, 18 Oct 2012 05:43:52 +0000 Subject: Temporarily revert the TargetTransform changes. The TargetTransform changes are breaking LTO bootstraps of clang. I am working with Nadav to figure out the problem, but I am reverting it for now to get our buildbots working. This reverts svn commits: 165665 165669 165670 165786 165787 165997 and I have also reverted clang svn 165741 llvm-svn: 166168 --- llvm/lib/Analysis/ScalarEvolutionExpander.cpp | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) (limited to 'llvm/lib/Analysis/ScalarEvolutionExpander.cpp') diff --git a/llvm/lib/Analysis/ScalarEvolutionExpander.cpp b/llvm/lib/Analysis/ScalarEvolutionExpander.cpp index 5c2a49e767f..5e05f4c8ca1 100644 --- a/llvm/lib/Analysis/ScalarEvolutionExpander.cpp +++ b/llvm/lib/Analysis/ScalarEvolutionExpander.cpp @@ -19,8 +19,8 @@ #include "llvm/LLVMContext.h" #include "llvm/Support/Debug.h" #include "llvm/DataLayout.h" +#include "llvm/Target/TargetLowering.h" #include "llvm/ADT/STLExtras.h" -#include "llvm/TargetTransformInfo.h" using namespace llvm; @@ -1599,15 +1599,15 @@ static bool width_descending(Value *lhs, Value *rhs) { /// This does not depend on any SCEVExpander state but should be used in /// the same context that SCEVExpander is used. unsigned SCEVExpander::replaceCongruentIVs(Loop *L, const DominatorTree *DT, - SmallVectorImpl &DeadInsts, - const ScalarTargetTransformInfo *STTI) { + SmallVectorImpl &DeadInsts, + const TargetLowering *TLI) { // Find integer phis in order of increasing width.
