From bf60aa9db5953dd99c561dfa9323b1e3293a5a85 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Fri, 3 Aug 2012 20:19:44 +0000 Subject: Eliminate the VNInfo::hasPHIKill() flag. The only real user of the flag was removeCopyByCommutingDef(), and it has been switched to LiveIntervals::hasPHIKill(). All the code changed by this patch was only concerned with computing and propagating the flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161255 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/LiveIntervalAnalysis.cpp | 3 --- 1 file changed, 3 deletions(-) (limited to 'lib/CodeGen/LiveIntervalAnalysis.cpp') diff --git a/lib/CodeGen/LiveIntervalAnalysis.cpp b/lib/CodeGen/LiveIntervalAnalysis.cpp index 54d665595c..bbc8c52872 100644 --- a/lib/CodeGen/LiveIntervalAnalysis.cpp +++ b/lib/CodeGen/LiveIntervalAnalysis.cpp @@ -256,7 +256,6 @@ void LiveIntervals::handleVirtualRegisterDef(MachineBasicBlock *mbb, // new valno in the killing blocks. assert(vi.AliveBlocks.empty() && "Phi join can't pass through blocks"); DEBUG(dbgs() << " phi-join"); - ValNo->setHasPHIKill(true); } else { // Iterate over all of the blocks that the variable is completely // live in, adding [insrtIndex(begin), instrIndex(end)+4) to the @@ -357,7 +356,6 @@ void LiveIntervals::handleVirtualRegisterDef(MachineBasicBlock *mbb, SlotIndex killIndex = getMBBEndIdx(mbb); LiveRange LR(defIndex, killIndex, ValNo); interval.addRange(LR); - ValNo->setHasPHIKill(true); DEBUG(dbgs() << " phi-join +" << LR); } else { llvm_unreachable("Multiply defined register"); @@ -823,7 +821,6 @@ LiveRange LiveIntervals::addLiveRangeToEndOfBlock(unsigned reg, VNInfo* VN = Interval.getNextValue( SlotIndex(getInstructionIndex(startInst).getRegSlot()), getVNInfoAllocator()); - VN->setHasPHIKill(true); LiveRange LR( SlotIndex(getInstructionIndex(startInst).getRegSlot()), getMBBEndIdx(startInst->getParent()), VN); -- cgit v1.2.3
