|
|
|
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 generic instantiation depends on
|
|
|
30 -- a generic procedure that is changed.
|
|
|
31 --
|
|
|
32 -- TEST DESCRIPTION:
|
|
|
33 -- This test compiles a generic procedure, a second generic
|
|
|
34 -- procedure, a generic instantiation of the second procedure
|
|
|
35 -- that depends on both the first and second generic
|
|
|
36 -- procedures, and a main procedure that withs the instantiated
|
|
|
37 -- procedure. Then, a new version of the first generic
|
|
|
38 -- procedure is compiled (in a separate file, simulating
|
|
|
39 -- editing and modification to the unit). Unless automatic
|
|
|
40 -- recompilation is supported, this test should fail to link.
|
|
|
41 -- Otherwise, the test should recompile and link the correct
|
|
|
42 -- version of the withed function and report "PASSED" at
|
|
|
43 -- execution time.
|
|
|
44 --
|
|
|
45 -- SPECIAL REQUIREMENTS:
|
|
|
46 -- To build this test:
|
|
|
47 -- 1) Compile the file LA140220 (and include the results in the
|
|
|
48 -- program library).
|
|
|
49 -- 2) Compile the file LA140221 (and include the results in the
|
|
|
50 -- program library).
|
|
|
51 -- 3) Compile the file LA140222 (and include the results in the
|
|
|
52 -- program library).
|
|
|
53 -- 4) Attempt to build an executable image.
|
|
|
54 -- 5) If an executable image results, run it.
|
|
|
55 --
|
|
|
56 -- TEST FILES:
|
|
|
57 -- This test consists of the following files:
|
|
|
58 -- LA140220.A
|
|
|
59 -- -> LA140221.AM
|
|
|
60 -- LA140222.A
|
|
|
61 --
|
|
|
62 -- PASS/FAIL CRITERIA:
|
|
|
63 -- The test passes if a link time error message reports that
|
|
|
64 -- LA14022_2 is missing or obsolete and no executable image
|
|
|
65 -- results. The test also passes if an executable image is produced
|
|
|
66 -- and reports "PASSED" (in the case where the implementation supports
|
|
|
67 -- automatic recompilation).
|
|
|

|
|
69 -- CHANGE HISTORY:
|
|
|
70 -- 01 MAY 95 ACVC 1.12 LA5008S baseline version
|
|
|
71 -- 23 JUN 95 SAIC Initial version
|
|
|
72 -- 18 NOV 96 SAIC Modified unit names and prologue to conform
|
|
|
73 -- to coding conventions.
|
|
|
74 -- 07 DEC 96 SAIC Moved LA14022_0 to a separate file. Added
|
|

75 -- pragma Elaborate to context clause of
