Public Member Functions
const NameIndex * getNameIndex () const
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< uint64_t > getLocalTUOffset () const override
Returns the Offset of the Type Unit associated with this Accelerator Entry or std::nullopt if the Type Unit offset is not recorded in this Accelerator Entry.
std::optional< uint64_t > getForeignTUTypeSignature () const override
Returns the type signature of the Type Unit associated with this Accelerator Entry or std::nullopt if the Type 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 > getRelatedCUOffset () const
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.
std::optional< uint64_t > getRelatedCUIndex () const
Similar functionality to getCUIndex() but without the DW_IDX_type_unit restriction.
std::optional< uint64_t > getTUIndex () const
Returns the index of the Type Unit of the owning Name Index or std::nullopt if this Accelerator Entry does not have an associated Type 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.
bool hasParentInformation () const
Returns true if this Entry has information about its parent DIE (i.e.
Expected< std::optional< DWARFDebugNames::Entry > > getParentDIEEntry () const
Returns the Entry corresponding to the parent of the DIE represented by this Entry.
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.

◆ getAbbrev()

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

◆ 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, unless there is a DW_IDX_type_unit attribute.
