| -- 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 package body depends on a generic package |
| -- specification. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test compiles a generic package specification and body, |
| -- followed by a procedure that makes a call to a procedure |
| -- contained inside the generic package. Then, the generic package |
| -- specification is recompiled, making the body of the generic |
| -- package obsolete. Unless automatic recompilation is |
| -- supported this test should fail to link. Otherwise, the test should |
| -- recompile and link the correct version of the units and report |
| -- "PASSED" at execution time. |
| -- |
| -- SPECIAL REQUIREMENTS: |
| -- To build this test: |
| -- 1) Compile the file LA140050 (and include the results in the |
| -- program library). |
| -- 2) Compile the file LA140051 (and include the results in the |
| -- program library). |
| -- 3) Compile the file LA140052 (and include the results in the |
| -- program library). |
| -- 4) Compile the file LA140053 (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: |
| -- LA140050.A |
| -- LA140051.A |
| -- -> LA140052.AM |
| -- LA140053.A |
| -- |
| -- PASS/FAIL CRITERIA: |
| -- Expect a link-time error message that the body of generic |
| -- package LA14005_1 is missing or obsolete. If automatic |
| -- recompilation is supported, and an executable image is |
| -- built, expect a "PASSED" message from execution. |
