--
-- Grant of Unlimited Rights
--
-- The Ada Conformity Assessment Authority (ACAA) holds unlimited
-- rights in the software and documentation contained herein. Unlimited
-- rights are the same as those granted by the U.S. Government for older
-- parts of the Ada Conformity Assessment Test Suite, and are defined
-- in DFAR 252.227-7013(a)(19). By making this public release, the ACAA
-- intends to confer upon all recipients unlimited rights equal to those
-- held by the ACAA. These rights include rights to use, duplicate,
-- release or disclose the released technical data and computer software
-- in whole or in part, in any manner and for any purpose whatsoever, and
-- to have or permit others to do so.

-- DISCLAIMER

-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE ACAA MAKES NO EXPRESS OR IMPLIED

--
-- Notice
--
-- The ACAA has created and maintains the Ada Conformity Assessment Test
-- Suite for the purpose of conformity assessments conducted in accordance
-- with the International Standard ISO/IEC 18009 - Ada: Conformity
-- assessment of a language processor. This test suite should not be used
-- to make claims of conformance unless used in accordance with
-- ISO/IEC 18009 and any applicable ACAA procedures.
--*
--
-- OBJECTIVE:
-- For X'Old given in the postcondition for a subprogram S, check that
-- X'Old has the same tag as X when X is a parameter P of S, even if the
-- tag of X is different than the nominal subtype of P. (Part 2:
-- Post'Class)
--
-- TEST DESCRIPTION:
-- We declare an event counter type and an extension thereof. We include
-- function calls that are bound based on the type of the prefix, and
-- check which are called.
--
-- To check the objective, we directly check the tag. It would have been
-- more usage-oriented to test dispatching instead, but that would have
-- added more complication to the test.
--
-- TEST FILES:
-- This test consists of the following files:
-- -> C611B020.A
-- C611B021.A
-- C611B022.AM
--
-- CHANGE HISTORY:
-- 21 Mar 16 JAC Initial pre-release version.
-- 24 Mar 16 RLB Renamed so all test parts have same first 7
-- characters.
--
