◆ 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()

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

Get the offset the parser has reached.

◆ 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.
