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.

Definition at line 356 of file DWARFDebugLine.h.

◆ getOffset()

uint64_t llvm::DWARFDebugLine::SectionParser::getOffset ( ) const

inline

Get the offset the parser has reached.

Definition at line 359 of file DWARFDebugLine.h.

◆ parseNext()

DWARFDebugLine::LineTable DWARFDebugLine::SectionParser::parseNext	(	function_ref< void(Error)>	RecoverableErrorHandler,
		function_ref< void(Error)>	UnrecoverableErrorHandler,
		raw_ostream *	OS = `nullptr`,
		bool	Verbose = `false`
	)

Get the next line table from the section.

Report any issues via the handlers.

Parameters

RecoverableErrorHandler	- any issues that don't prevent further parsing of the table will be reported through this handler.
UnrecoverableErrorHandler	- any issues that prevent further parsing of the table will be reported through this handler.
OS	- if not null, the parser will print information about the table as it parses it.
Verbose	- if true, the parser will print verbose information when printing to the output.

◆ skip()

void DWARFDebugLine::SectionParser::skip	(	function_ref< void(Error)>	RecoverableErrorHandler,
		function_ref< void(Error)>	UnrecoverableErrorHandler
	)

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

Parameters

RecoverableErrorHandler	- report any recoverable prologue parsing issues via this handler.
UnrecoverableErrorHandler	- report any unrecoverable prologue parsing issues via this handler.
