class AddrLabelMap

Declaration

class AddrLabelMap { /* full declaration omitted */ };

Declared at: llvm/lib/CodeGen/AsmPrinter/AsmPrinter.cpp:176

Member Variables

private llvm::MCContext& Context

private DenseMap<AssertingVH<llvm::BasicBlock>, llvm::AddrLabelMap::AddrLabelSymEntry> AddrLabelSymbols

private std::vector<AddrLabelMapCallbackPtr> BBCallbacks

Callbacks for the BasicBlock's that we have entries for. We use this so we get notified if a block is deleted or RAUWd.

private DenseMap<AssertingVH<llvm::Function>, std::vector<MCSymbol*>> DeletedAddrLabelsNeedingEmission

This is a per-function list of symbols whose corresponding BasicBlock got deleted. These symbols need to be emitted at some point in the file, so AsmPrinter emits them after the function body.

Method Overview

• public AddrLabelMap(llvm::MCContext & context)
• public void UpdateForDeletedBlock(llvm::BasicBlock * BB)
• public void UpdateForRAUWBlock(llvm::BasicBlock * Old, llvm::BasicBlock * New)
• public ArrayRef<llvm::MCSymbol *> getAddrLabelSymbolToEmit(llvm::BasicBlock * BB)
• public void takeDeletedSymbolsForFunction(llvm::Function * F, std::vector<MCSymbol *> & Result)
• public ~AddrLabelMap()
