Member Function Documentation

begin()

iterator llvm::DWARFDebugFrame::begin ( ) const

inline

DWARF Frame entries accessors.

Definition at line 269 of file DWARFDebugFrame.h.

dump()

void DWARFDebugFrame::dump	(	raw_ostream &	OS,
		DIDumpOptions	DumpOpts,
		std::optional< uint64_t >	Offset ) const

Dump the section data into the given stream.

Definition at line 476 of file DWARFDebugFrame.cpp.

References llvm::DIDumpOptions::IsEH, and llvm::Offset.

empty()

bool llvm::DWARFDebugFrame::empty ( ) const

inline

Return whether the section has any entries.

Definition at line 266 of file DWARFDebugFrame.h.

end()

iterator llvm::DWARFDebugFrame::end ( ) const

inline

Definition at line 270 of file DWARFDebugFrame.h.

entries()

iterator_range< iterator > llvm::DWARFDebugFrame::entries ( ) const

inline

Definition at line 271 of file DWARFDebugFrame.h.

getEHFrameAddress()

uint64_t llvm::DWARFDebugFrame::getEHFrameAddress ( ) const

inline

Definition at line 273 of file DWARFDebugFrame.h.

References uint64_t.

parse()

Error DWARFDebugFrame::parse	(	DWARFDataExtractor	Data,
		bool	ParseCFIProgram = true )

Parse the section from raw data.

Data is assumed to contain the whole frame section contents to be parsed.

If ParseCFIProgram is false, the CFI instruction program of each entry is not decoded; callers can parse individual programs on demand through parseCFIProgram(), as long as Data stays valid.

parseAllCFIPrograms()

Error DWARFDebugFrame::parseAllCFIPrograms

(

)

const

Decode all the CFI instruction programs that parse() was told to skip.

parseCFIProgram()

Error DWARFDebugFrame::parseCFIProgram

(

dwarf::FrameEntry &

const

Decode the CFI instruction program of Entry if parse() was told to skip it.
