-- 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
-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE
-- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE
-- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A
-- PARTICULAR PURPOSE OF SAID MATERIAL.
--
-- 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.
--*
-- OBJECTIVES:
-- Check that the "=" operator of a language-defined nonlimited private
-- type is used in the equality for a record type containing a component of
-- the type. Part 1: Core types.
--
-- TEST DESCRIPTION:
-- This test also checks for reemergence of some other operation in a
-- generic, and for use in the equality for an array type.
--
-- The foundation is used to do the actual checks; this unit just has
-- to set up appropriate values.
--
-- Note that this test could pass even if the type is incorrectly
-- implemented if the predefined equality and the user-defined equality
-- happen to get the same result for the values used in this test.
--
-- This test is less likely to fail for a correct Ada 2012 implementation
-- than for an implementation for earlier versions of Ada, as Ada 2012
-- requires all record types to compose properly (this was only true of
-- tagged types in earlier versions).
--
-- CHANGE HISTORY:
-- 25 JAN 2001 PHL Initial version.
-- 19 Dec 2018 RLB Created test from submitted version; added
-- missing cases for Exception_Id and Time.
