void appendRow (const DWARFDebugLine::Row &R)
void appendSequence (const DWARFDebugLine::Sequence &S)
LLVM_ABI uint32_t lookupAddress (object::SectionedAddress Address, bool *IsApproximateLine=nullptr) const
Returns the index of the row with file/line info for a given address, or UnknownRowIndex if there is no such row.
LLVM_ABI bool lookupAddressRange (object::SectionedAddress Address, uint64_t Size, std::vector< uint32_t > &Result, std::optional< uint64_t > StmtSequenceOffset=std::nullopt) const
Fills the Result argument with the indices of the rows that correspond to the address range specified by Address and Size.

std::optional< uint64_t > getLastValidFileIndex () const
bool getFileNameByIndex (uint64_t FileIndex, StringRef CompDir, DILineInfoSpecifier::FileLineInfoKind Kind, std::string &Result) const
Extracts filename by its index in filename table in prologue.
LLVM_ABI bool getFileLineInfoForAddress (object::SectionedAddress Address, bool Approximate, const char *CompDir, DILineInfoSpecifier::FileLineInfoKind Kind, DILineInfo &Result) const
Fills the Result argument with the file and line information corresponding to Address.
LLVM_ABI bool getDirectoryForEntry (const FileNameEntry &Entry, std::string &Directory) const
Extracts directory name by its Entry in include directories table in prologue.
