| -- 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 function that is changed. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test compiles a generic function, a generic |
| -- instantiation of the generic function, and a main |
| -- procedure that withs the instantiated generic |
| -- function. Then, a new version of the first generic |
| -- function is compiled (in a separate file, simulating |
| -- editing and modification to the unit). The test should |
| -- link the correct version of the withed function and |
| -- report "PASSED" at execution time. |
| -- |
| -- Note that compilers are required by the standard to support |
| -- replacement of a generic body without recompilation of the |
| -- instantation. The ARG confirmed 10.1.4(10) with AI-00077. |
| -- |
| -- To build this test: |
| -- 1) Compile the file CA140230 (and include the results in the |
| -- program library). |
| -- 2) Compile the file CA140231 (and include the results in the |
| -- program library). |
| -- 3) Compile the file CA140232 (and include the results in the |
| -- program library). |
| -- 4) Compile the file CA140233 (and include the results in the |
| -- program library). |
| -- 5) Build and run an executable image. |
| -- |
| -- TEST FILES: |
| -- This test consists of the following files: |
| -- CA140230.A |
| -- CA140231.A |
| -- -> CA140232.AM |
| -- CA140233.A |
| -- |
| -- CHANGE HISTORY: |
| -- 01 MAY 95 ACVC 1.12 LA5008T baseline version |
| -- 29 JUN 95 SAIC Initial version |
| -- 05 MAR 96 SAIC First revision after review |
| -- 18 NOV 96 SAIC Modified unit names and prologue to conform |
| -- to coding conventions. |
| -- 07 DEC 96 SAIC Moved CA14023_1 to a separate file. |
| -- 13 SEP 99 RLB Changed to C-test (by AI-00077). |
| -- 20 MAR 00 RLB Removed special requirements, because there |
| -- aren't any. |
