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 generic instantiation depends on
30
--      a generic package instantiation that is changed.
31
--
32
-- TEST DESCRIPTION:
33
--      This test compiles a generic package, a generic
34
--      instantiation of the generic package, another generic
35
--      package, a generic instantiation of the second generic
36
--      package that withs the first generic instantiation
37
--      packages, and a main procedure that withs the instantiated
38
--      generic package.  Then, a new version of the first generic
39
--      package is compiled (in a separate file, simulating
40
--      editing and modification to the unit).  Unless automatic
41
--      recompilation is supported, this test should fail to link.
42
--      Otherwise, the test should recompile and link the correct
43
--      version of the instantiation and report "PASSED" at
44
--      execution time.
45
--
46
-- SPECIAL REQUIREMENTS:
47
--      To build this test:
48
--         1) Compile the file LA140260 (and include the results in the
49
--            program library).
50
--         2) Compile the file LA140261 (and include the results in the
51
--            program library).
52
--         3) Compile the file LA140262 (and include the results in the
53
--            program library).
54
--         4) Compile the file LA140263 (and include the results in the
55
--            program library).
56
--         5) Attempt to build an executable image.
57
--         6) If an executable image results, run it.
58
--
59
-- TEST FILES:
60
--      This test consists of the following files:
61
--         LA140260.A
62
--         LA140261.A
63
--      -> LA140262.AM
64
--         LA140263.A
65
--
66
-- PASS/FAIL CRITERIA:
67
--      The test passes if a link time error message reports that
68
--      LA140260 is missing or obsolete, or that LA14026_5 is
69
--      missing or obsolete (optional) and no executable image
70
--      results.  The test also passes if an executable image is produced
71
--      and reports "PASSED" (in the case where the implementation supports
72
--      automatic recompilation).
73
--
74
-- CHANGE HISTORY:
75
--     01 MAY 95   ACVC 1.12   LA5008W baseline version
76
--     06 JUL 95   SAIC        Initial version
77
--     18 NOV 96   SAIC        Modified unit names and prologue to conform
78
--                             to coding conventions.
79
--     07 DEC 96   SAIC        Moved LA14026_3 to a separate file. Added
80
--                             pragma Elaborate to context clause of LA14026_5.
