-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained
-- unlimited rights in the software and documentation contained herein.
-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.
-- 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 GOVERNMENT MAKES NO EXPRESS OR IMPLIED
-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE

--*
--
-- OBJECTIVE:
-- Check that a compilation unit may not depend semantically
-- on two different versions of the same compilation unit.
-- Check the case where a generic instantiation depends on
-- a generic package instantiation that is changed.
--
-- TEST DESCRIPTION:
-- This test compiles a generic package, a generic
-- instantiation of the generic package, another generic
-- package, a generic instantiation of the second generic
-- package that withs the first generic instantiation
-- packages, and a main procedure that withs the instantiated
-- generic package. Then, a new version of the first generic
-- package is compiled (in a separate file, simulating
-- editing and modification to the unit). Unless automatic
-- recompilation is supported, this test should fail to link.
-- Otherwise, the test should recompile and link the correct
-- version of the instantiation and report "PASSED" at
-- execution time.
--
-- SPECIAL REQUIREMENTS:
-- To build this test:
-- 1) Compile the file LA140260 (and include the results in the
-- program library).
-- 2) Compile the file LA140261 (and include the results in the
-- program library).
-- 3) Compile the file LA140262 (and include the results in the
-- program library).
-- 4) Compile the file LA140263 (and include the results in the
-- program library).
-- 5) Attempt to build an executable image.
-- 6) If an executable image results, run it.
--
-- TEST FILES:
-- This test consists of the following files:
-- LA140260.A
-- LA140261.A
-- -> LA140262.AM
-- LA140263.A
--
-- PASS/FAIL CRITERIA:
-- The test passes if a link time error message reports that
-- LA140260 is missing or obsolete, or that LA14026_5 is
-- missing or obsolete (optional) and no executable image
-- results. The test also passes if an executable image is produced
-- and reports "PASSED" (in the case where the implementation supports
-- automatic recompilation).
--
-- CHANGE HISTORY:
-- 01 MAY 95 ACVC 1.12 LA5008W baseline version
-- 06 JUL 95 SAIC Initial version
-- 18 NOV 96 SAIC Modified unit names and prologue to conform
-- to coding conventions.
-- 07 DEC 96 SAIC Moved LA14026_3 to a separate file. Added
-- pragma Elaborate to context clause of LA14026_5.
