-- Several kinds of declaration node permit aspect specifications in Ada
-- 2012 mode. If there was room in all these declaration nodes, we could
-- just have a field Aspect_Specifications pointing to a list of nodes
-- for the aspects (N_Aspect_Specification nodes). But there isn't room,
-- so we adopt a different approach.
-- The following subprograms provide access to a specialized interface
-- implemented internally with a hash table in the body, that provides
-- access to aspect specifications.
function Permits_Aspect_Specifications (N : Node_Id) return Boolean;
-- Returns True if the node N is a declaration node that permits aspect
-- specifications. All such nodes have the Has_Aspect_Specifications
-- flag defined. Returns False for all other nodes.
function Aspect_Specifications (N : Node_Id) return List_Id;
-- Given a node N, returns the list of N_Aspect_Specification nodes that
-- are attached to this declaration node. If the node is in the class of
-- declaration nodes that permit aspect specifications, as defined by the
-- predicate above, and if their Has_Aspect_Specifications flag is set to
-- True, then this will always be a non-empty list. If this flag is set to
-- False, or the node is not in the declaration class permitting aspect
-- specifications, then No_List is returned.
procedure Set_Aspect_Specifications (N : Node_Id; L : List_Id);
-- The node N must be in the class of declaration nodes that permit aspect
-- specifications and the Has_Aspect_Specifications flag must be False on
-- entry. L must be a non-empty list of N_Aspect_Specification nodes. This
-- procedure sets the Has_Aspect_Specifications flag to True, and makes an
-- entry that can be retrieved by a subsequent Aspect_Specifications call.
-- The parent of list L is set to reference the declaration node N. It is
-- an error to call this procedure with a node that does not permit aspect
-- specifications, or a node that has its Has_Aspect_Specifications flag
-- set True on entry, or with L being an empty list or No_List.
