| -- Referenced entity |
| |
| Ref_Scope : Entity_Id; |
| -- Scope where the reference occurs |
| |
| Rtype : Character; |
| -- Indicates type of the reference, using code used in ALI file: |
| -- r = reference |
| -- m = modification |

| |
| Name_Of_Heap_Variable : constant String := "__HEAP"; |
| -- Name of special variable used in effects to denote reads and writes |
| -- through explicit dereference. |
| |
| Heap : Entity_Id := Empty; |
| -- A special entity which denotes the heap object; it should be considered |
| -- constant, but needs to be variable, because it can only be initialized |
| -- after the node tables are created. Also, it is only created if there is |
| -- an actual need for it, and remains Empty otherwise. |
