-- 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
-- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE

--*
--
-- 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 non-generic package that is changed.
--
-- TEST DESCRIPTION:
-- This test compiles a package, a generic package, a
-- generic instantiation that withs both of the first two
-- packages, and a main procedure that withs the instantiated
-- generic package. Then, a new version of the first
-- 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 withed package and report "PASSED" at
-- execution time.
--
-- SPECIAL REQUIREMENTS:
-- To build this test:
-- 1) Compile the file LA140250 (and include the results in the
-- program library).
-- 2) Compile the file LA140251 (and include the results in the
-- program library).
-- 3) Compile the file LA140252 (and include the results in the
-- program library).
-- 4) Attempt to build an executable image.
-- 5) If an executable image results, run it.
--
-- TEST FILES:
-- This test consists of the following files:
-- LA140250.A
-- -> LA140251.AM
-- LA140252.A
--
-- PASS/FAIL CRITERIA:
-- The test passes if a link time error message reports that
-- LA14025 is missing or obsolete, or that LA14025_2 is
-- missing or obsolete (optional) and no executable image
-- results. The test passes if an executable image is produced
-- and reports "PASSED" (in case the implementation supports
-- automatic recompilation).

--
-- CHANGE HISTORY:
-- 01 MAY 95 ACVC 1.12 LA5008V baseline version
-- 06 JUL 95 SAIC Initial version
-- 08 NOV 96 SAIC Unit naming correction
-- 07 DEC 96 SAIC Moved LA14025_0 to a separate file. Added
-- pragma Elaborate to context clause of
-- LA14025_2.
