--

-- 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 function semantically

--      depends on a library level generic function that is changed.

--

-- TEST DESCRIPTION:

--      This test compiles a generic function, and a procedure that

--      withs the function.  Then, a new version of the generic

--      function body is compiled (in a separate file, simulating

--      and 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 withed function and report "PASSED" at

--      execution time.

--

-- SPECIAL REQUIREMENTS:

--      To build this test:

--         1) Compile the file LA140170 (and include the results in the

--            program library).

--         2) Compile the file LA140171 (and include the results in the

--            program library).

--         3) Compile the file LA140172 (and include the results in the

--            program library).

--         4) Compile the file LA140173 (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:

--         LA140170.A

--         LA140171.A

--      -> LA140172.AM

--         LA140173.A

--

-- PASS/FAIL CRITERIA:

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

--      LA14017_1.Inc 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   LA5008M baseline version

--     16 JUN 95   SAIC        Initial version

--     03 MAR 96   SAIC        First revision after review

--     17 NOV 96   SAIC        Modified unit names and prologue to conform

--                             to coding conventions.

--     07 DEC 96   SAIC        Moved LA14017_1 to a separate file.
