    const DWARFDebugLine::Sequence& S)

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLine.h:234

Parameters

const DWARFDebugLine::Sequence& S

¶void clear()

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLine.h:272

¶void dump(llvm::raw_ostream& OS,
          llvm::DIDumpOptions DumpOptions) const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLine.h:271

Parameters

llvm::raw_ostream& OS

llvm::DIDumpOptions DumpOptions

¶uint32_t findRowInSeq(
    const DWARFDebugLine::Sequence& Seq,
    object::SectionedAddress Address) const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLine.h:290

Parameters

const DWARFDebugLine::Sequence& Seq

object::SectionedAddress Address

¶bool getFileLineInfoForAddress(
    object::SectionedAddress Address,
    const char* CompDir,
    DILineInfoSpecifier::FileLineInfoKind Kind,
    llvm::DILineInfo& Result) const

Description

Fills the Result argument with the file and line information corresponding to Address. Returns true on success.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLine.h:266

Parameters

object::SectionedAddress Address

const char* CompDir

DILineInfoSpecifier::FileLineInfoKind Kind

Description

Extracts filename by its index in filename table in prologue. In Dwarf 4, the files are 1-indexed and the current compilation file name is not represented in the list. In DWARF v5, the files are 0-indexed and the primary source file has the index 0. Returns true on success.
