GetAttributes()

bool GetAttributes ( llvm::SmallVectorImpl< DWARFDIE > & worklist, llvm::SmallPtrSet< DWARFDebugInfoEntry const *, 3 > & seen, DWARFAttributes & attributes )

static

Helper for the public DWARFDebugInfoEntry::GetAttributes API.

Adds all attributes of the DIE at the top of the worklist to the attributes list. Specifcations and abstract origins are added to the worklist if the referenced DIE has not been seen before.
