| -- OBJECTIVE: |
| -- Check that a compilation unit may not depend semantically |
| -- on two different versions of the same compilation unit. |
| -- Check the case where a library level instance depends on |
| -- a library level generic function whose body is changed. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test compiles a generic function, an instance of a generic |
| -- function that withs the first function and a main procedure that |
| -- withs the instance. Then a new version of the first generic function |
| -- is compiled (in a separate file, simulating editing and modification |
| -- of 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 function and report "PASSED" |
| -- at execution time. |
| -- |
| -- SPECIAL REQUIREMENTS: |
| -- To build this test: |
| -- 1) Compile the file LA140200 (and include the results in the |
| -- program library). |
| -- 2) Compile the file LA140201 (and include the results in the |
| -- program library). |
| -- 3) Compile the file LA140202 (and include the results in the |
| -- program library). |
| -- 4) Compile the file LA140203 (and include the results in the |
| -- program library). |
| -- 5) Attempt to build an executable image. |
| -- 6) If an executable image results, run it. |
| -- |
| -- TEST FILES: |
| -- This test consists of the following files: |
| -- LA140200.A |
| -- LA140201.A |
| -- -> LA140202.AM |
| -- LA140203.A |
| -- |
| -- PASS/FAIL CRITERIA: |
| -- The test passes if a link time error message reports that |
| -- LA140202 is missing or obsolete, or that LA14020_3 or LA14020_4 |
| -- is missing or obsolete (optional) and no executable image |
| -- results. The test passes if an executable image is produced |
| -- and reports "PASSED" (in the case where the implementation |
| -- supports automatic recompilation). |
| -- |

| -- CHANGE HISTORY: |
| -- 01 MAY 95 ACVC 1.12 LA5008Q baseline version |
| -- 23 JUN 95 SAIC Initial version |
| -- 29 FEB 96 SAIC First revision after review |
| -- 12 DEC 96 SAIC Reorganized to permit automatic recompilation. |
| -- Reworded objective. Moved instance to |
| -- library-level and redesigned to use generic |
| -- formal function. Fixed arithmetic errors. |
