Member Function Documentation

done()

bool llvm::DWARFDebugLine::SectionParser::done ( ) const

inline

Indicates if the parser has parsed as much as possible.

Note

Certain problems with the line table structure might mean that parsing stops before the end of the section is reached.

getOffset()

uint32_t llvm::DWARFDebugLine::SectionParser::getOffset ( ) const

inline

Get the offset the parser has reached.

parseNext()

DWARFDebugLine::LineTable DWARFDebugLine::SectionParser::parseNext	(	function_ref< void(Error)>	RecoverableErrorCallback,
		function_ref< void(Error)>	UnrecoverableErrorCallback,
		raw_ostream *	OS = nullptr
	)

Get the next line table from the section.

Report any issues via the callbacks.

Parameters

RecoverableErrorCallback	- any issues that don't prevent further parsing of the table will be reported through this callback.
UnrecoverableErrorCallback	- any issues that prevent further parsing of the table will be reported through this callback.
OS	- if not null, the parser will print information about the table as it parses it.

skip()

void DWARFDebugLine::SectionParser::skip

(

function_ref< void(Error)>

ErrorCallback

)

Skip the current line table and go to the following line table (if present) immediately.

Parameters

ErrorCallback

- report any prologue parsing issues via this callback.
