class DWARFDebugInfoEntry

Declaration

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

Description

DWARFDebugInfoEntry - A DIE with only the minimum required data.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugInfoEntry.h:22

Member Variables

private uint64_t Offset = 0

Offset within the .debug_info of the start of this entry.

private uint32_t ParentIdx = (4294967295U)

Index of the parent die. UINT32_MAX if there is no parent.

private uint32_t SiblingIdx = 0

Index of the sibling die. Zero if there is no sibling.

private const llvm::DWARFAbbreviationDeclaration* AbbrevDecl = nullptr

Methods

¶DWARFDebugInfoEntry()

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugInfoEntry.h:35

¶bool extractFast(
    const llvm::DWARFUnit& U,
    uint64_t* OffsetPtr,
    const llvm::DWARFDataExtractor& DebugInfoData,
    uint64_t UEndOffset,
    uint32_t ParentIdx)

Description

Extracts a debug info entry, which is a child of a given unit, starting at a given offset. If DIE can't be extracted, returns false and doesn't change OffsetPtr. High performance extraction should use this call.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugInfoEntry.h:41

Parameters

const llvm::DWARFUnit& U

uint64_t* OffsetPtr

const llvm::DWARFDataExtractor& DebugInfoData

uint64_t UEndOffset

uint32_t ParentIdx
