Member Function Documentation

◆ getDefiningParentOutOffset()

std::optional< uint64_t > AcceleratorRecordsSaver::getDefiningParentOutOffset ( const DWARFDebugInfoEntry * InputDieEntry )

protected

Return the output offset of InputDieEntry's immediate non-declaration parent, for use as the DW_IDX_parent field of a name index entry.

Matches classic's one-level lookup: does not walk past a pruned or declaration parent to find a surviving ancestor. Returns std::nullopt if there is no usable parent.

◆ save()

void AcceleratorRecordsSaver::save	(	const DWARFDebugInfoEntry *	InputDieEntry,
		DIE *	OutDIE,
		AttributesInfo &	AttrInfo,
		TypeEntry *	TypeEntry )

Save accelerator info for the specified OutDIE inside OutUnit.

Side effects: set attributes in AttrInfo.
