| -- Lock Free Data Structure -- |
| ------------------------------ |
| |
| -- A lock-free subprogram is a protected routine which references a unique |
| -- protected scalar component and does not contain statements that cause |
| -- side effects. Due to this restricted behavior, all references to shared |
| -- data from within the subprogram can be synchronized through the use of |
| -- atomic operations rather than relying on locks. |
| |
| type Lock_Free_Subprogram is record |
| Sub_Body : Node_Id; |
| -- Reference to the body of a protected subprogram which meets the lock- |
| -- free requirements. |
| |
| Comp_Id : Entity_Id; |
| -- Reference to the scalar component referenced from within Sub_Body |
| end record; |
| |
| -- This table establishes a relation between a protected subprogram body |
| -- and a unique component it references. The table is used when building |
| -- the lock-free versions of a protected subprogram body. |
