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 separate procedure depends
30 -- on a withed generic package that is changed.
31 --
32 -- TEST DESCRIPTION:
33 -- This test declares a package which contains a generic procedure GP,
34 -- the body of which is a subunit. The package also contains a procedure
35 -- P which instantiates GP and calls the instance. The instance itself
36 -- calls a procedure which is declared within the instance of a generic
37 -- package X. The test compiles each of these compilation units and the
38 -- main procedure, then compiles a new version of the generic package X
39 -- (in a separate file, simulating an editing modification to the unit).
40 -- Unless automatic recompilation is supported, this test should fail to
41 -- link. Otherwise, the test should recompile and link the correct
42 -- version of the generic package X and report "PASSED" at execution time.
43 --
44 -- SPECIAL REQUIREMENTS:
45 -- To build this test:
46 -- 1) Compile the file LA140160 (and include the results in the
47 -- program library).
48 -- 2) Compile the file LA140161 (and include the results in the
49 -- program library).
50 -- 3) Compile the file LA140162 (and include the results in the
51 -- program library).
52 -- 4) Compile the file LA140163 (and include the results in the
53 -- program library).
54 -- 5) Attempt to build an executable image.
55 -- 6) If an executable image results, run it.
56 --
57 -- TEST FILES:
58 -- This test consists of the following files:
59 -- LA140160.A
60 -- LA140161.A
61 -- -> LA140162.AM
62 -- LA140163.A
63 --
64 -- PASS/FAIL CRITERIA:
65 -- The test passes if a link time error message reports that
66 -- LA14016_4.gen_def is missing or obsolete and no executable
67 -- image results. The test also passes if an executable image is
68 -- produced and reports "PASSED" (in the case where the implementation
69 -- supports automatic recompilation).

72 -- CHANGE HISTORY:
73 -- 01 MAY 95 ACVC 1.12 LA5008L baseline version
74 -- 16 JUN 95 SAIC Initial version
75 -- 07 DEC 96 SAIC Modified unit names and prologue to conform
76 -- to coding conventions. Restructured subunits
77 -- to prevent potential Program_Error due to
78 -- premature instantiation of gen_def. Moved
79 -- LA14016_1 to a separate file. Added pragma
80 -- Elaborate to context clause of LA14016_3.
