From 61e4a0bc10fa1d36d58935d42d248180993d65bb Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Wed, 30 Jun 2010 18:19:08 +0000 Subject: Remember to track spill slot uses in VirtRegMap when inserting loads and stores. LocalRewriter::runOnMachineFunction uses this information to mark dead spill slots. This means that InlineSpiller now also works for functions that spill. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107302 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/Spiller.cpp | 2 ++ 1 file changed, 2 insertions(+) (limited to 'lib/CodeGen/Spiller.cpp') diff --git a/lib/CodeGen/Spiller.cpp b/lib/CodeGen/Spiller.cpp index ad65e9f4b2..19987afef1 100644 --- a/lib/CodeGen/Spiller.cpp +++ b/lib/CodeGen/Spiller.cpp @@ -137,6 +137,7 @@ protected: MachineInstr *loadInstr(prior(miItr)); SlotIndex loadIndex = lis->InsertMachineInstrInMaps(loadInstr).getDefIndex(); + vrm->addSpilSlotUse(ss, loadInstr); SlotIndex endIndex = loadIndex.getNextIndex(); VNInfo *loadVNI = newLI->getNextValue(loadIndex, 0, true, lis->getVNInfoAllocator()); @@ -150,6 +151,7 @@ protected: MachineInstr *storeInstr(llvm::next(miItr)); SlotIndex storeIndex = lis->InsertMachineInstrInMaps(storeInstr).getDefIndex(); + vrm->addSpilSlotUse(ss, storeInstr); SlotIndex beginIndex = storeIndex.getPrevIndex(); VNInfo *storeVNI = newLI->getNextValue(beginIndex, 0, true, lis->getVNInfoAllocator()); -- cgit v1.2.3-70-g09d2
