|
|
|
25 --
|
|
|
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).
|
|
|
70 --
|
|
|
71 --
|
|
|
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.
