Member Function Documentation

AddEntry()

void LineTableInfo::AddEntry	(	FileID	FID,
		const std::vector< LineEntry > &	Entries )

Add a new line entry that has already been encoded into the internal representation of the line table.

Definition at line 253 of file SourceManager.cpp.

AddLineNote()

void LineTableInfo::AddLineNote	(	FileID	FID,
		unsigned	Offset,
		unsigned	LineNo,
		int	FilenameID,
		unsigned	EntryExit,
		SrcMgr::CharacteristicKind	FileKind )

Add a line note to the line table that indicates that there is a #line or GNU line marker at the specified FID/Offset location which changes the presumed location to LineNo/FilenameID.

If EntryExit is 0, then this doesn't change the presumed #include stack. If it is 1, this is a file entry, if it is 2 then this is a file exit. FileKind specifies whether this is a system header or extern C system header.

FindNearestLineEntry()

const LineEntry * LineTableInfo::FindNearestLineEntry	(	FileID	FID,
		unsigned	Offset )

Find the line entry nearest to FID that is before it.

FindNearestLineEntry - Find the line entry nearest to FID that is before it.

If there is no line entry before Offset in FID, returns null.

If there is no line entry before Offset in FID, return null.
