Declaration

class DwarfUnit : public DIEUnit { /* full declaration omitted */ };

Description

This dwarf writer support class manages information associated with a source file.

Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfUnit.h:35

Inherits from: DIEUnit

Member Variables

protected const llvm::DICompileUnit* CUNode

MDNode for the compile unit.

protected llvm::BumpPtrAllocator DIEValueAllocator

protected llvm::AsmPrinter* Asm

Target of Dwarf emission.

protected llvm::MCSymbol* EndLabel = nullptr

Emitted at the end of the CU and used to compute the CU Length field.

protected llvm::DwarfDebug* DD

protected llvm::DwarfFile* DU

protected llvm::DIE* IndexTyDie = nullptr

An anonymous type for index type. Owned by DIEUnit.

protected DenseMap<const llvm::MDNode*, llvm::DIE*> MDNodeToDieMap

Tracks the mapping of unit level debug information variables to debug information entries.

protected std::vector<DIEBlock*> DIEBlocks

A list of all the DIEBlocks in use.

protected std::vector<DIELoc*> DIELocs

A list of all the DIELocs in use.

protected DenseMap<llvm::DIE*, const llvm::DINode*> ContainingTypeMap

This map is used to keep track of subprogram DIEs that need DW_AT_containing_type attribute. This attribute points to a DIE that corresponds to the MDNode mapped with the subprogram DIE.

¶std::string getParentContextString(
    const llvm::DIScope* Context) const

Description

Get string containing language specific context for a global name. Walks the metadata parent chain in a language specific manner (using the compile unit language) and returns it as a string. This is done at the metadata level because DIEs may not currently have been added to the parent context and walking the DIEs looking for names is more expensive than walking the metadata.

Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfUnit.h:112

Parameters

¶void insertDIE(const llvm::DINode* Desc,
               llvm::DIE* D)

Description
