| -- OBJECTIVE: |
| -- Check that a Size clause for an object is supported if the specified |
| -- size is at least as large as the subtype's size, and correspond to a |
| -- size in storage elements that is a multiple of the object's (non-zero) |
| -- Alignment. RM 13.3(43) |
| -- |
| -- TEST DESCRIPTION: |
| -- This test defines several types and then asserts specific sizes for |
| -- the, it then checks that the size set is reported back. |
| -- |
| -- 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 Corrected and strengthened for 2.1 |
| -- 14 FEB 97 PWB.CTA Changed 'Size specifications to multiples |
| -- of System.Storage_Unit; restricted 'Size spec |
| -- for enumeration object to max integer size. |
| -- 16 FEB 98 EDS Modify Documentation. |
| -- 25 JAN 99 RLB Repaired to properly set and check sizes. |
| -- 29 JAN 99 RLB Added Pack pragma needed for some implementations. |
| -- Corrected to support a Storage_Unit size < 8. |
