From bd8e650876cc93952dde3120938271dbda6cbbb7 Mon Sep 17 00:00:00 2001 From: Dale Johannesen Date: Tue, 3 Mar 2009 01:09:07 +0000 Subject: When sinking an insn in InstCombine bring its debug info with it. Don't count debug info insns against the scan maximum in FindAvailableLoadedValue (lest they affect codegen). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65910 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Transforms/Utils/BasicBlockUtils.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'include/llvm/Transforms/Utils/BasicBlockUtils.h') diff --git a/include/llvm/Transforms/Utils/BasicBlockUtils.h b/include/llvm/Transforms/Utils/BasicBlockUtils.h index 429d3b6..a629b11 100644 --- a/include/llvm/Transforms/Utils/BasicBlockUtils.h +++ b/include/llvm/Transforms/Utils/BasicBlockUtils.h @@ -60,6 +60,11 @@ void ReplaceInstWithInst(BasicBlock::InstListType &BIL, // void ReplaceInstWithInst(Instruction *From, Instruction *To); +/// CopyPrecedingStopPoint - If I is immediately preceded by a StopPoint, +/// make a copy of the stoppoint before InsertPos (presumably before copying +/// or moving I). +void CopyPrecedingStopPoint(Instruction *I, BasicBlock::iterator InsertPos); + /// FindAvailableLoadedValue - Scan the ScanBB block backwards (starting at the /// instruction before ScanFrom) checking to see if we have the value at the /// memory address *Ptr locally available within a small number of instructions. -- cgit v1.1
