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
76 -- LA14022_2.
