Public Member Functions
std::optional< uint64_t >	getCUOffset () const override
	Returns the Offset of the Compilation Unit associated with this Accelerator Entry or std::nullopt if the Compilation Unit offset is not recorded in this Accelerator Entry.

std::optional< dwarf::Tag >	getTag () const override
	Returns the Tag of the Debug Info Entry associated with this Accelerator Entry or std::nullopt if the Tag is not recorded in this Accelerator Entry.

std::optional< uint64_t >	getCUIndex () const
	Returns the Index into the Compilation Unit list of the owning Name Index or std::nullopt if this Accelerator Entry does not have an associated Compilation Unit.

dwarf::Tag	tag () const
	.debug_names-specific getter, which always succeeds (DWARF v5 index entries always have a tag).

std::optional< uint64_t >	getDIEUnitOffset () const
	Returns the Offset of the DIE within the containing CU or TU.

const Abbrev &	getAbbrev () const
	Return the Abbreviation that can be used to interpret the raw values of this Accelerator Entry.

std::optional< DWARFFormValue >	lookup (dwarf::Index Index) const
	Returns the value of the Index Attribute in this Accelerator Entry, if the Entry contains such Attribute.

◆ dump()

void DWARFDebugNames::Entry::dump ( ScopedPrinter & W ) const

Definition at line 571 of file DWARFAcceleratorTable.cpp.

References assert(), llvm::DWARFDebugNames::Abbrev::Attributes, llvm::DWARFDebugNames::Abbrev::Code, llvm::formatv(), llvm::DWARFDebugNames::Abbrev::Tag, and llvm::zip_first().

◆ getAbbrev()

const Abbrev & llvm::DWARFDebugNames::Entry::getAbbrev ( ) const

inline

Return the Abbreviation that can be used to interpret the raw values of this Accelerator Entry.

Definition at line 313 of file DWARFAcceleratorTable.h.

◆ getCUIndex()

std::optional< uint64_t > DWARFDebugNames::Entry::getCUIndex ( ) const

Returns the Index into the Compilation Unit list of the owning Name Index or std::nullopt if this Accelerator Entry does not have an associated Compilation Unit.

It is up to the user to verify that the returned Index is valid in the owning NameIndex (or use getCUOffset(), which will handle that check itself). Note that entries in NameIndexes which index just a single Compilation Unit are implicitly associated with that unit, so this function will return 0 even without an explicit DW_IDX_compile_unit attribute.
