--

-- 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 package body depends on a generic package

--      specification.

--

-- TEST DESCRIPTION:

--      This test compiles a generic package specification and body,

--      followed by a procedure that makes a call to a procedure

--      contained inside the generic package.  Then, the generic package

--      specification is recompiled, making the body of the generic

--      package obsolete.  Unless automatic recompilation is

--      supported this test should fail to link.  Otherwise, the test should

--      recompile and link the correct version of the units and report

--      "PASSED" at execution time.

--

-- SPECIAL REQUIREMENTS:

--      To build this test:

--         1) Compile the file LA140050 (and include the results in the

--            program library).

--         2) Compile the file LA140051 (and include the results in the

--            program library).

--         3) Compile the file LA140052 (and include the results in the

--            program library).

--         4) Compile the file LA140053 (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:

--         LA140050.A

--         LA140051.A

--      -> LA140052.AM

--         LA140053.A

--

-- PASS/FAIL CRITERIA:

--      Expect a link-time error message that the body of generic

--      package LA14005_1 is missing or obsolete.  If automatic

--      recompilation is supported, and an executable image is

--      built, expect a "PASSED" message from execution.

--

--

-- CHANGE HISTORY:

--     01 MAY 95   ACVC 1.12   LA5008I baseline version

--     09 MAY 95   SAIC        Initial version

--     08 NOV 96   SAIC        Unit naming correction

--     07 DEC 96   SAIC        Moved spec of LA14005_1 to a separate file.
