| -- 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 generic package instantiation that is changed. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test compiles a generic package, a generic |
| -- instantiation of the generic package, another generic |
| -- package, a generic instantiation of the second generic |
| -- package that withs the first generic instantiation |
| -- packages, and a main procedure that withs the instantiated |
| -- generic package. Then, a new version of the first generic |
| -- 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 instantiation and report "PASSED" at |
| -- execution time. |
| -- |
| -- SPECIAL REQUIREMENTS: |
| -- To build this test: |
| -- 1) Compile the file LA140260 (and include the results in the |
| -- program library). |
| -- 2) Compile the file LA140261 (and include the results in the |
| -- program library). |
| -- 3) Compile the file LA140262 (and include the results in the |
| -- program library). |
| -- 4) Compile the file LA140263 (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: |
| -- LA140260.A |
| -- LA140261.A |
| -- -> LA140262.AM |
| -- LA140263.A |
| -- |
| -- PASS/FAIL CRITERIA: |
| -- The test passes if a link time error message reports that |
| -- LA140260 is missing or obsolete, or that LA14026_5 is |
| -- missing or obsolete (optional) 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 LA5008W baseline version |
| -- 06 JUL 95 SAIC Initial version |
| -- 18 NOV 96 SAIC Modified unit names and prologue to conform |
| -- to coding conventions. |
| -- 07 DEC 96 SAIC Moved LA14026_3 to a separate file. Added |
| -- pragma Elaborate to context clause of LA14026_5. |
