--

-- OBJECTIVE:

--      Check that a compilation unit may not depend semantically

--      on two different versions of the same compilation unit.

--      Check the case where a library level instance depends on

--      a library level generic function whose body is changed.

--

-- TEST DESCRIPTION:

--      This test compiles a generic function, an instance of a generic

--      function that withs the first function and a main procedure that

--      withs the instance.  Then a new version of the first generic function

--      is compiled (in a separate file, simulating editing and modification

--      of 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 LA140200 (and include the results in the

--            program library).

--         2) Compile the file LA140201 (and include the results in the

--            program library).

--         3) Compile the file LA140202 (and include the results in the

--            program library).

--         4) Compile the file LA140203 (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:

--         LA140200.A

--         LA140201.A

--      -> LA140202.AM

--         LA140203.A

--

-- PASS/FAIL CRITERIA:

--      The test passes if a link time error message reports that

--      LA140202 is missing or obsolete, or that LA14020_3 or LA14020_4

--      is missing or obsolete (optional) and no executable image

--      results.  The test 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   LA5008Q baseline version

--     23 JUN 95   SAIC        Initial version

--     29 FEB 96   SAIC        First revision after review

--     12 DEC 96   SAIC        Reorganized to permit automatic recompilation.

--                             Reworded objective. Moved instance to

--                             library-level and redesigned to use generic

--                             formal function. Fixed arithmetic errors.
