Member Function Documentation

◆ dump()

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

◆ 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 310 of file DWARFAcceleratorTable.h.

References llvm::DWARFAcceleratorTable::dump(), lookup(), and llvm::RISCVFenceField::W.

◆ getCUIndex()

Optional< uint64_t > DWARFDebugNames::Entry::getCUIndex ( ) const

Returns the Index into the Compilation Unit list of the owning Name Index or None 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.

References llvm::DWARFDebugNames::NameIndex::getCUCount(), lookup(), and llvm::None.

◆ getCUOffset()

Optional< uint64_t > DWARFDebugNames::Entry::getCUOffset ( ) const
overridevirtual

Returns the Offset of the Compilation Unit associated with this Accelerator Entry or None if the Compilation Unit offset is not recorded in this Accelerator Entry.

Implements llvm::DWARFAcceleratorTable::Entry.

References llvm::DWARFDebugNames::NameIndex::getCUCount(), llvm::DWARFDebugNames::NameIndex::getCUOffset(), and llvm::None.

◆ getDIEUnitOffset()

Optional< uint64_t > DWARFDebugNames::Entry::getDIEUnitOffset ( ) const

Returns the Offset of the DIE within the containing CU or TU.

References lookup(), and llvm::None.

◆ getTag()

Optional<dwarf::Tag> llvm::DWARFDebugNames::Entry::getTag ( ) const
inlineoverridevirtual

Returns the Tag of the Debug Info Entry associated with this Accelerator Entry or None if the Tag is not recorded in this Accelerator Entry.

Implements llvm::DWARFAcceleratorTable::Entry.

Definition at line 289 of file DWARFAcceleratorTable.h.

◆ lookup()

Optional< DWARFFormValue > DWARFDebugNames::Entry::lookup ( dwarf::Index  Index) const

Returns the value of the Index Attribute in this Accelerator Entry, if the Entry contains such Attribute.

Definition at line 532 of file DWARFAcceleratorTable.cpp.

References assert(), llvm::DWARFDebugNames::Abbrev::Attributes, llvm::None, and llvm::zip_first().

◆ tag()

dwarf::Tag llvm::DWARFDebugNames::Entry::tag ( ) const
inline

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