--

-- 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 function that is changed.

--

-- TEST DESCRIPTION:

--      This test compiles a generic function, a generic

--      instantiation of the generic function, and a main

--      procedure that withs the instantiated generic

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

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

--      editing and modification to the unit).  The test should

--      link the correct version of the withed function and

--      report "PASSED" at execution time.

--

--      Note that compilers are required by the standard to support

--      replacement of a generic body without recompilation of the

--      instantation. The ARG confirmed 10.1.4(10) with AI-00077.

--

--      To build this test:

--         1) Compile the file CA140230 (and include the results in the

--            program library).

--         2) Compile the file CA140231 (and include the results in the

--            program library).

--         3) Compile the file CA140232 (and include the results in the

--            program library).

--         4) Compile the file CA140233 (and include the results in the

--            program library).

--         5) Build and run an executable image.

--

-- TEST FILES:

--      This test consists of the following files:

--         CA140230.A

--         CA140231.A

--      -> CA140232.AM

--         CA140233.A

--

-- CHANGE HISTORY:

--     01 MAY 95   ACVC 1.12   LA5008T baseline version

--     29 JUN 95   SAIC        Initial version

--     05 MAR 96   SAIC        First revision after review

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

--                             to coding conventions.

--     07 DEC 96   SAIC        Moved CA14023_1 to a separate file.

--     13 SEP 99   RLB         Changed to C-test (by AI-00077).

--     20 MAR 00   RLB         Removed special requirements, because there

--                             aren't any.
