- procedure Expand_N_Full_Type_Declaration (N : Node_Id);
-
- procedure Expand_Previous_Access_Type (N : Node_Id; Def_Id : Entity_Id);
- -- For a full type declaration that contains tasks, or that is a task,
- -- check whether there exists an access type whose designated type is an
- -- incomplete declarations for the current composite type. If so, build
- -- the master for that access type, now that it is known to denote an
- -- object with tasks.
-
- procedure Expand_Derived_Record (T : Entity_Id; Def : Node_Id);
- -- Add a field _parent in the extension part of the record.
-
- procedure Build_Discr_Checking_Funcs (N : Node_Id);
- -- Builds function which checks whether the component name is consistent
- -- with the current discriminants. N is the full type declaration node,
- -- and the discriminant checking functions are inserted after this node.

- function Build_Initialization_Call
- (Loc : Source_Ptr;
- Id_Ref : Node_Id;
- Typ : Entity_Id;
- In_Init_Proc : Boolean := False;
- Enclos_Type : Entity_Id := Empty;
- Discr_Map : Elist_Id := New_Elmt_List)
- return List_Id;
- -- Builds a call to the initialization procedure of the Id entity. Id_Ref
- -- is either a new reference to Id (for record fields), or an indexed
- -- component (for array elements). Loc is the source location for the
- -- constructed tree, and Typ is the type of the entity (the initialization
- -- procedure of the base type is the procedure that actually gets called).
- -- In_Init_Proc has to be set to True when the call is itself in an Init
- -- procedure in order to enable the use of discriminals. Enclos_type is
- -- the type of the init_proc and it is used for various expansion cases
- -- including the case where Typ is a task type which is a array component,
- -- the indices of the enclosing type are used to build the string that
- -- identifies each task at runtime.
- --
- -- Discr_Map is used to replace discriminants by their discriminals in
- -- expressions used to constrain record components. In the presence of
- -- entry families bounded by discriminants, protected type discriminants
- -- can appear within expressions in array bounds (not as stand-alone
- -- identifiers) and a general replacement is necessary.
-
- procedure Freeze_Type (N : Node_Id);
- -- This procedure executes the freezing actions associated with the given
- -- freeze type node N.
-
- function Needs_Simple_Initialization (T : Entity_Id) return Boolean;
- -- Certain types need initialization even though there is no specific
- -- initialization routine. In this category are access types (which
- -- need initializing to null), packed array types whose implementation
- -- is a modular type, and all scalar types if Normalize_Scalars is set,
- -- as well as private types whose underlying type is present and meets
- -- any of these criteria. Finally, descendants of String and Wide_String
- -- also need initialization in Initialize/Normalize_Scalars mode.
-
- function Get_Simple_Init_Val
- (T : Entity_Id;
- Loc : Source_Ptr)
- return Node_Id;
- -- For a type which Needs_Simple_Initialization (see above), prepares
- -- the tree for an expression representing the required initial value.
- -- Loc is the source location used in constructing this tree which is
- -- returned as the result of the call.
