-- 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 "=" for all language-defined nonlimited private types
-- behaves as if it is predefined for composition and for
-- formal types - Part 3: Annex C 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.
--
-- Notes: We only need to test private types here, as language-defined
-- scalar type equality is tested elsewhere.
--
-- 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. With the function
-- being tested returning only two distinct values, that is definitely
-- possible.
--
-- 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).
--
-- APPLICABILITY CRITERIA:
-- All implementations must attempt to compile this test.
--
-- For implementations validating against Systems Programming Annex (C):
-- this test must execute and report PASSED.
--
-- or implementations not validating against Annex C:
-- this test may report compile time errors at one or more points
-- indicated by "-- ANX-C RQMT", in which case it may be graded as
-- inapplicable. Otherwise, the test must execute and report PASSED.
--
-- CHANGE HISTORY:
-- 25 JAN 2001 PHL Initial version.
-- 19 Dec 2018 RLB Created test from submitted version.
-- 20 Dec 2018 RLB Added Null_Task_Id subtest. Revised to use Impdef
-- values for delays.
