| -- 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 procedure depends |
| -- on a withed generic package that is changed. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test declares a package which contains a generic procedure GP, |
| -- the body of which is a subunit. The package also contains a procedure |
| -- P which instantiates GP and calls the instance. The instance itself |
| -- calls a procedure which is declared within the instance of a generic |
| -- package X. The test compiles each of these compilation units and the |
| -- main procedure, then compiles a new version of the generic package X |
| -- (in a separate file, simulating an 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 generic package X and report "PASSED" at execution time. |
| -- |
| -- SPECIAL REQUIREMENTS: |
| -- To build this test: |
| -- 1) Compile the file LA140160 (and include the results in the |
| -- program library). |
| -- 2) Compile the file LA140161 (and include the results in the |
| -- program library). |
| -- 3) Compile the file LA140162 (and include the results in the |
| -- program library). |
| -- 4) Compile the file LA140163 (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: |
| -- LA140160.A |
| -- LA140161.A |
| -- -> LA140162.AM |
| -- LA140163.A |
| -- |
| -- PASS/FAIL CRITERIA: |
| -- The test passes if a link time error message reports that |
| -- LA14016_4.gen_def 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). |

| -- CHANGE HISTORY: |
| -- 01 MAY 95 ACVC 1.12 LA5008L baseline version |
| -- 16 JUN 95 SAIC Initial version |
| -- 07 DEC 96 SAIC Modified unit names and prologue to conform |
| -- to coding conventions. Restructured subunits |
| -- to prevent potential Program_Error due to |
| -- premature instantiation of gen_def. Moved |
| -- LA14016_1 to a separate file. Added pragma |
| -- Elaborate to context clause of LA14016_3. |
