-- 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

-- 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 procedure that is changed.
--
-- TEST DESCRIPTION:
-- This test compiles a generic procedure, a second generic
-- procedure, a generic instantiation of the second procedure
-- that depends on both the first and second generic
-- procedures, and a main procedure that withs the instantiated
-- procedure. Then, a new version of the first generic
-- procedure 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 function and report "PASSED" at
-- execution time.
--
-- SPECIAL REQUIREMENTS:
-- To build this test:
-- 1) Compile the file LA140220 (and include the results in the
-- program library).
-- 2) Compile the file LA140221 (and include the results in the
-- program library).
-- 3) Compile the file LA140222 (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:
-- LA140220.A
-- -> LA140221.AM
-- LA140222.A
--
-- PASS/FAIL CRITERIA:
-- The test passes if a link time error message reports that
-- LA14022_2 is missing or obsolete 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 LA5008S baseline version
-- 23 JUN 95 SAIC Initial version
-- 18 NOV 96 SAIC Modified unit names and prologue to conform
-- to coding conventions.
-- 07 DEC 96 SAIC Moved LA14022_0 to a separate file. Added
-- pragma Elaborate to context clause of
-- LA14022_2.
