class DWARFListTableBase

Declaration

template <typename DWARFListType>
class DWARFListTableBase { /* full declaration omitted */ };

Description

A class representing a table of lists as specified in the DWARF v5 standard for location lists and range lists. The table consists of a header followed by an array of offsets into a DWARF section, followed by zero or more list entries. The list entries are kept in a map where the keys are the lists' section offsets.

Parameters

llvm::StringRef SectionName

llvm::StringRef HeaderString

llvm::StringRef ListTypeString

¶void clear()

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFListTable.h:154

¶void dump(llvm::raw_ostream& OS,
          llvm::function_ref<
              Optional<object::SectionedAddress>(
                  uint32_t)> LookupPooledAddress,
          llvm::DIDumpOptions DumpOpts = {}) const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFListTable.h:172

Parameters

llvm::raw_ostream& OS

llvm::function_ref< Optional<object::SectionedAddress>(uint32_t)> LookupPooledAddress

llvm::DIDumpOptions DumpOpts = {}

¶llvm::Error extract(llvm::DWARFDataExtractor Data,
                    uint64_t* OffsetPtr)

Description

Extract an entire table, including all list entries.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFListTable.h:163

Parameters

llvm::DWARFDataExtractor Data

uint64_t* OffsetPtr

¶llvm::Error extractHeaderAndOffsets(
    llvm::DWARFDataExtractor Data,
    uint64_t* OffsetPtr)

Description

Extract the table header and the array of offsets.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFListTable.h:159

Parameters

llvm::DWARFDataExtractor Data

uint64_t* OffsetPtr

¶Expected<DWARFListType> findList(
    llvm::DWARFDataExtractor Data,
    uint64_t Offset)

Description

Look up a list based on a given offset. Extract it and enter it into the list map if necessary.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFListTable.h:166

Parameters

llvm::DWARFDataExtractor Data

uint64_t Offset

¶uint8_t getAddrSize() const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFListTable.h:169

¶dwarf::DwarfFormat getFormat() const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFListTable.h:170

¶uint64_t getHeaderOffset() const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFListTable.h:168

¶uint8_t getHeaderSize() const

Description

Return the size of the table header including the length but not including the offsets. This is dependent on the table format, which is unambiguously derived from parsing the table.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFListTable.h:184

¶Optional<uint64_t> getOffsetEntry(
    uint32_t Index) const

Description

Return the contents of the offset entry designated by a given index.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFListTable.h:178

Parameters

uint32_t Index

¶uint64_t length()

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFListTable.h:188
