| -- This package deals with the implementation of the Local_Restrictions aspect |
| |
| with Types; use Types; |
| |
| package Local_Restrict is |
| type Local_Restriction is (No_Secondary_Stack, No_Heap_Allocations); |
| -- A local restriction can be mentioned in a Local_Restrictions aspect |
| -- specification. A local restriction might apply, for example, to a |
| -- single subprogram. No_Secondary_Stack corresponds to the |
| -- GNAT-defined restriction of the same name. No_Heap_Allocations |
| -- corresponds to the conjunction of the RM-defined restrictions |
| -- No_Allocators and No_Implicit_Heap_Allocations. If a subprogram is |
| -- subject to a local restriction, then any subprogram that it calls |
| -- shall be known to satisfy that restriction. |
| |
| type Local_Restriction_Set is array (Local_Restriction) of Boolean; |
| |
| procedure Check_Call (Call : Node_Id; Callee : Entity_Id := Empty); |
| -- Check whether a call violates any local restrictions that are |
| -- in effect. An empty callee indicates that the callee should be |
| -- conservatively assumed to violate any local restrictions that |
| -- are in effect (for example, for an entry call or a call through |
| -- an access-to-subprogram value). |
| |
| procedure Check_Overriding (Overrider_Op, Overridden_Op : Entity_Id); |
| -- Check that all of the local restrictions in effect for |
| -- Overridden_Op are also in effect for Overrider_Op. |
| |
| procedure Check_Actual_Subprogram_For_Instance |
| (Actual_Subp_Name : Node_Id; Formal_Subp : Entity_Id); |
| -- Check that all of the local restrictions in effect for |
| -- Formal_Subp are also in effect for Actual_Subp. |
