26
-- OBJECTIVE:
27
--      Check that the full view of a private extension may be derived
28
--      indirectly from the ancestor type (i.e., the parent type of the full
29
--      type may be any descendant of the ancestor type). Check that, for
30
--      a primitive subprogram of the private extension that is inherited from
31
--      the ancestor type and not overridden, the formal parameter names and
32
--      default expressions come from the corresponding primitive subprogram
33
--      of the ancestor type, while the body comes from that of the parent
34
--      type.  Check both dispatching and non-dispatching cases.
35
--
36
-- TEST DESCRIPTION:
37
--      Consider:
38
--
39
--      package P is
40
--         type Ancestor is tagged ...
41
--         procedure Op (P1: Ancestor; P2: Boolean := True);
42
--      end P;
43
--
44
--      with P;
45
--      package Q is
46
--         type Derived is new P.Ancestor with ...
47
--         procedure Op (X: Ancestor; Y: Boolean := False);
48
--      end Q;
49
--
50
--      with P, Q;
51
--      package R is
52
--         type Priv_Ext is new P.Ancestor with private;   -- (A)
53
--         -- Inherits procedure Op (P1: Priv_Ext; P2: Boolean := True);
54
--         -- But body executed is that of Q.Op.
55
--      private
56
--         type Priv_Ext is new Q.Derived with record ...  -- (B)
57
--      end R;
58
--
59
--      The ancestor type in (A) differs from the parent type in (B); the
60
--      parent of the full type is descended from the ancestor type of the
61
--      private extension. For a call to Op (from outside the scope of the
62
--      full view) with an operand of type Priv_Ext, the formal parameter
63
--      names and default expression come from that of P.Op (the ancestor
64
--      type's version), but the body executed will be that of
65
--      Q.Op (the parent type's version)
66
--
67
--      One half of the test mirrors the above template, where an inherited
68
--      subprogram (Set_Display) is called using the formal parameter
69
--      name (C) and default parameter expression of the ancestor type's
70
--      version (type Clock), but the version of the body executed is from
71
--      the parent type.
72
--
73
--      The test also includes an examination of the dynamic evaluation
74
--      case, where correct body associations are required through dispatching
75
--      calls.  As described for the non-dispatching case above, the formal
76
--      parameter name and default values of the ancestor type's (Phone)
77
--      version of the inherited subprogram (Answer) are used in the
78
--      dispatching call, but the body executed is from the parent type.
