| -- OBJECTIVE: |
| -- Check that a compilation unit may not depend semantically |
| -- on two different versions of the same compilation unit. |
| -- Check the case where a generic instantiation depends on |
| -- a non-generic package that is changed. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test compiles a package, a generic package, a |
| -- generic instantiation that withs both of the first two |
| -- packages, and a main procedure that withs the instantiated |
| -- generic package. Then, a new version of the first |
| -- package is compiled (in a separate file, simulating |
| -- editing and modification to the unit). Unless automatic |
| -- recompilation is supported, this test should fail to link. |
| -- Otherwise, the test should recompile and link the correct |
| -- version of the withed package and report "PASSED" at |
| -- execution time. |
| -- |
| -- SPECIAL REQUIREMENTS: |
| -- To build this test: |
| -- 1) Compile the file LA140250 (and include the results in the |
| -- program library). |
| -- 2) Compile the file LA140251 (and include the results in the |
| -- program library). |
| -- 3) Compile the file LA140252 (and include the results in the |
| -- program library). |
| -- 4) Attempt to build an executable image. |
| -- 5) If an executable image results, run it. |
| -- |
| -- TEST FILES: |
| -- This test consists of the following files: |
| -- LA140250.A |
| -- -> LA140251.AM |
| -- LA140252.A |
| -- |
| -- PASS/FAIL CRITERIA: |
| -- The test passes if a link time error message reports that |
| -- LA14025 is missing or obsolete, or that LA14025_2 is |
| -- missing or obsolete (optional) and no executable image |
| -- results. The test passes if an executable image is produced |
| -- and reports "PASSED" (in case the implementation supports |
| -- automatic recompilation). |
