-- 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
-- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A
-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that a compilation unit may not depend semantically
-- on two different versions of the same compilation unit.
-- Check the case where a separate procedure depends
-- on a withed generic package that is changed.
--
-- TEST DESCRIPTION:
-- This test declares a package which contains a generic procedure GP,
-- the body of which is a subunit. The package also contains a procedure
-- P which instantiates GP and calls the instance. The instance itself
-- calls a procedure which is declared within the instance of a generic
-- package X. The test compiles each of these compilation units and the
-- main procedure, then compiles a new version of the generic package X
-- (in a separate file, simulating an editing 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 generic package X and report "PASSED" at execution time.
--
-- SPECIAL REQUIREMENTS:
-- To build this test:
-- 1) Compile the file LA140160 (and include the results in the
-- program library).
-- 2) Compile the file LA140161 (and include the results in the
-- program library).
-- 3) Compile the file LA140162 (and include the results in the
-- program library).
-- 4) Compile the file LA140163 (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:
-- LA140160.A
-- LA140161.A
-- -> LA140162.AM
-- LA140163.A
--
-- PASS/FAIL CRITERIA:
-- The test passes if a link time error message reports that
-- LA14016_4.gen_def 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 LA5008L baseline version
-- 16 JUN 95 SAIC Initial version
-- 07 DEC 96 SAIC Modified unit names and prologue to conform
-- to coding conventions. Restructured subunits
-- to prevent potential Program_Error due to
-- premature instantiation of gen_def. Moved
-- LA14016_1 to a separate file. Added pragma
-- Elaborate to context clause of LA14016_3.
