| --* |
| -- |
| -- OBJECTIVE: |
| -- Check that for packed records the components are packed as tightly |
| -- as possible subject to the Size of the component subtypes. |
| -- Specifically check that Boolean objects are packed one to a bit. |
| -- |
| -- Check that the Component_Size for a packed array type is less than |
| -- or equal to the smallest of those factors of the word size that are |
| -- greater than or equal to the Size of the component subtype. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test defines and packs several types, and checks that the sizes |
| -- of the resulting objects is as expected. |
| -- |
| -- APPLICABILITY CRITERIA: |
| -- All implementations must attempt to compile this test. |
| -- |
| -- For implementations validating against Systems Programming Annex (C): |
| -- this test must execute and report PASSED. |
| -- |
| -- For implementations not validating against Annex C: |
| -- this test may report compile time errors at one or more points |
| -- indicated by "-- ANX-C RQMT", in which case it may be graded as |
| -- inapplicable. Otherwise, the test must execute and report PASSED. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 22 JUL 95 SAIC Initial version |
| -- 08 MAY 96 SAIC Strengthened for 2.1 |
| -- 29 JAN 98 EDS Deleted check that Component_Size is really a |
| -- factor of Word_Size. |
