---------------------------------------------------
-- Handling of Aspect Specifications in the Tree --
---------------------------------------------------
-- Several kinds of declaration node permit aspect specifications in Ada
-- 2012 mode. If there was room in all the corresponding 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 in the grammar. It is possible for other nodes to have
-- aspect specifications as a result of Rewrite or Replace calls.
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_Aspects flag is set to True, then this
-- will always be a non-empty list. If this flag is set to False, then
-- No_List is returned. Normally, the only nodes that have Has_Aspects set
-- True are the nodes for which Permits_Aspect_Specifications would return
-- True (i.e. the declaration nodes defined in the RM as permitting the
-- presence of Aspect_Specifications). However, it is possible for the
-- flag Has_Aspects to be set on other nodes as a result of Rewrite and
-- Replace calls, and this function may be used to retrieve the aspect
-- specifications for the original rewritten node in such cases.
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_Aspects flag must be False on entry. L must
-- be a non-empty list of N_Aspect_Specification nodes. This procedure sets
-- the Has_Aspects flag to True, and makes an entry that can be retrieved
-- by a subsequent Aspect_Specifications call. It is an error to call this
-- procedure with a node that does not permit aspect specifications, or a
-- node that has its Has_Aspects flag set True on entry, or with L being an
-- empty list or No_List.
procedure Move_Aspects (From : Node_Id; To : Node_Id);
-- Moves aspects from 'From' node to 'To' node. Has_Aspects (To) must be
-- False on entry. If Has_Aspects (From) is False, the call has no effect.
-- Otherwise the aspects are moved and on return Has_Aspects (To) is True,
-- and Has_Aspects (From) is False.
procedure Tree_Write;
-- Writes contents of Aspect_Specifications hash table to the tree file
procedure Tree_Read;
-- Reads contents of Aspect_Specifications hash table from the tree file
end Aspects;
