Member Function Documentation

extractFast()

bool DWARFDebugInfoEntry::extractFast	(	const DWARFUnit &	U,
		uint64_t *	OffsetPtr,
		const DWARFDataExtractor &	DebugInfoData,
		uint64_t	UEndOffset,
		uint32_t	ParentIdx )

Extracts a debug info entry, which is a child of a given unit, starting at a given offset.

If DIE can't be extracted, returns false and doesn't change OffsetPtr. High performance extraction should use this call.
