...teresting -- I didn't know we had this! Two reasons it can't be used directly: - Here, the element type is actually a `std::pair<>`, with `.first` being a tag for the type of attachment (really this is a low-mem map from tag to pointer). - The pointer type needs to have `MetadataTracking` support so that LLParser, BitcodeReader, and DIBuilder can assign a temporary attachment that later gets RAUW'ed. However, if I'm going to roll a custom type anyway, I might as well go full hog: - Make the "large" vector `std::pair<unsigned, TrackingMDNodeRef>`....
