◆ dump()

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

Definition at line 564 of file DWARFAcceleratorTable.cpp.

References assert(), llvm::DWARFDebugNames::Abbrev::Attributes, llvm::DWARFDebugNames::Abbrev::Code, llvm::AppleAcceleratorTable::dump(), llvm::formatv(), llvm::ScopedPrinter::getOStream(), llvm::DWARFDebugNames::SentinelError::ID, llvm::ScopedPrinter::printHex(), llvm::ScopedPrinter::startLine(), 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 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.
