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 function semantically
30 -- depends on a library level generic function that is changed.
31 --
32 -- TEST DESCRIPTION:
33 -- This test compiles a generic function, and a procedure that
34 -- withs the function. Then, a new version of the generic
35 -- function body is compiled (in a separate file, simulating
36 -- and editing modification to the unit). Unless automatic
37 -- recompilation is supported, this test should fail to link.
38 -- Otherwise, the test should recompile and link the correct
39 -- version of the withed function and report "PASSED" at
40 -- execution time.
41 --
42 -- SPECIAL REQUIREMENTS:
43 -- To build this test:
44 -- 1) Compile the file LA140170 (and include the results in the
45 -- program library).
46 -- 2) Compile the file LA140171 (and include the results in the
47 -- program library).
48 -- 3) Compile the file LA140172 (and include the results in the
49 -- program library).
50 -- 4) Compile the file LA140173 (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 -- LA140170.A
58 -- LA140171.A
59 -- -> LA140172.AM
60 -- LA140173.A
61 --
62 -- PASS/FAIL CRITERIA:
63 -- The test passes if a link time error message reports that
64 -- LA14017_1.Inc 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).
