From 81da02b553b86868637f27b89c6e919c31ed5b51 Mon Sep 17 00:00:00 2001 From: Dale Johannesen Date: Tue, 22 May 2007 17:14:46 +0000 Subject: Make tail merging the default, except on powerPC. There was no prior art for a target-dependent default with a command-line override; this way should be generally usable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37285 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/LLVMTargetMachine.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'lib/CodeGen/LLVMTargetMachine.cpp') diff --git a/lib/CodeGen/LLVMTargetMachine.cpp b/lib/CodeGen/LLVMTargetMachine.cpp index 34c45f3135..41f7e199a0 100644 --- a/lib/CodeGen/LLVMTargetMachine.cpp +++ b/lib/CodeGen/LLVMTargetMachine.cpp @@ -78,7 +78,7 @@ LLVMTargetMachine::addPassesToEmitFile(FunctionPassManager &PM, // Branch folding must be run after regalloc and prolog/epilog insertion. if (!Fast) - PM.add(createBranchFoldingPass()); + PM.add(createBranchFoldingPass(DoTailMergeDefault())); // Fold redundant debug labels.
