26
-- OBJECTIVE:
27
--      Check that a compilation unit may not depend semantically
28
--      on two different versions of the same compilation unit.
29
--      Check the case where a library level instance depends on
30
--      a library level generic function whose body is changed.
31
--
32
-- TEST DESCRIPTION:
33
--      This test compiles a generic function, an instance of a generic
34
--      function that withs the first function and a main procedure that
35
--      withs the instance.  Then a new version of the first generic function
36
--      is compiled (in a separate file, simulating editing and modification
37
--      of the unit).  Unless automatic recompilation is supported, this
38
--      test should fail to link. Otherwise, the test should recompile and
39
--      link the correct version of the withed function and report "PASSED"
40
--      at execution time.
41
--
42
-- SPECIAL REQUIREMENTS:
43
--      To build this test:
44
--         1) Compile the file LA140200 (and include the results in the
45
--            program library).
46
--         2) Compile the file LA140201 (and include the results in the
47
--            program library).
48
--         3) Compile the file LA140202 (and include the results in the
49
--            program library).
50
--         4) Compile the file LA140203 (and include the results in the
51
--            program library).
52
--         5) Attempt to build an executable image.
53
--         6) If an executable image results, run it.
54
--
55
-- TEST FILES:
56
--      This test consists of the following files:
57
--         LA140200.A
58
--         LA140201.A
59
--      -> LA140202.AM
60
--         LA140203.A
61
--
62
-- PASS/FAIL CRITERIA:
63
--      The test passes if a link time error message reports that
64
--      LA140202 is missing or obsolete, or that LA14020_3 or LA14020_4
65
--      is missing or obsolete (optional) and no executable image
66
--      results.  The test passes if an executable image is produced
67
--      and reports "PASSED" (in the case where the implementation
68
--      supports automatic recompilation).

71
-- CHANGE HISTORY:
72
--     01 MAY 95   ACVC 1.12   LA5008Q baseline version
73
--     23 JUN 95   SAIC        Initial version
74
--     29 FEB 96   SAIC        First revision after review
75
--     12 DEC 96   SAIC        Reorganized to permit automatic recompilation.
76
--                             Reworded objective. Moved instance to
77
--                             library-level and redesigned to use generic
78
--                             formal function. Fixed arithmetic errors.
