| -- |
| -- OBJECTIVE: |
| -- Check that a compilation unit may not depend semantically |
| -- on two different versions of the same compilation unit. |
| -- Check the case where a separate generic package body depends |
| -- on a library level generic package body that is changed. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test compiles a generic package and its body, and a |
| -- procedure that withs the generic package. Then a new |
| -- version of the generic package body is compiled (in a |
| -- separate file, simulating and editing 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 with package |
| -- withed package and report "PASSED" at execution time. |
| -- |
| -- SPECIAL REQUIREMENTS: |
| -- To build this test: |
| -- 1) Compile the file LA140180 (and include the results in the |
| -- program library). |
| -- 2) Compile the file LA140181 (and include the results in the |
| -- program library). |
| -- 3) Compile the file LA140182 (and include the results in the |
| -- program library). |
| -- 4) Compile the file LA140183 (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: |
| -- LA140180.A |
| -- LA140181.A |
| -- -> LA140182.AM |
| -- LA140183.A |
| -- |
| -- PASS/FAIL CRITERIA: |
| -- The test passes if a link time error message reports that |
| -- LA14018_0.utils_18 is missing or obsolete and no executable image |
| -- results. The test also passes if an executable image is produced |
| -- and reports "PASSED" (in the case where the implementation supports |
| -- automatic recompilation). |

| -- 01 MAY 95 ACVC 1.12 LA5008N baseline version |
| -- 16 JUN 95 SAIC Initial version |
| -- 07 DEC 96 SAIC Modified unit names and prologue to conform |
| -- to coding conventions. Moved instantiation |
| -- of utils_18 to avoid potential Program_Error. |
| -- Moved LA14018_0 to a separate file. |
