The last significant one IIRC was Itanium, in the case of C++ member pointers (themselves an odd beast), which had a different representation than data pointers (-1 is null). -Chris _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
