-- 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.
end Local_Restrict;
