|
-- OBJECTIVE:
|
27 |
|
|
-- Check that representation items may contain nonstatic expressions
|
28 |
|
|
-- in the case that each expression in the representation item is a
|
29 |
|
|
-- name that statically denotes a constant declared before the entity.

|
-- TEST DESCRIPTION:
|
33 |
|
|
-- For each of the specific items in the objective, this test checks
|
34 |
|
|
-- an example of each of the categories of representation specification
|
35 |
|
|
-- that are applicable to that objective, to wit:
|
36 |
|
|
-- address clause ....................... Expressions need not be static
|
37 |
|
|
-- alignment clause ..................... Expressions must be static
|
38 |
|
|
-- bit order clause ..................... Not tested
|
39 |
|
|
-- component size clause ................ Expressions must be static
|
40 |
|
|
-- enumeration representation clause .... Expressions must be static
|
41 |

-- APPLICABILITY CRITERIA:
|
55 |
|
|
-- All implementations must attempt to compile this test.
|
56 |
|
|
--
|
57 |
|
|
-- For implementations validating against Systems Programming Annex (C):
|
58 |
|
|
-- this test must execute.
|
59 |
|
|
--
|
60 |
|
|
-- For implementations not validating against Annex C:

61 |
|
|
-- if this test compiles without error messages at compilation,
|
62 |

|
-- it must bind and execute.
|
63 |
|
|
--
|
64 |
|
|
-- PASS/FAIL CRITERIA:
|
65 |
|
|
-- For implementations validating against Systems Programming Annex (C):
|
66 |
|
|
-- this test must execute, report PASSED, and complete normally,
|
67 |
|
|
-- otherwise the test FAILS
|
68 |
|
|
--
|
69 |
|
|
-- For implementations not validating against Annex C:
|
70 |
|
|
-- PASSING behavior is:
|
71 |
|
|
-- this test executes, reports PASSED, and completes normally
|
72 |
|
|
-- or
|
73 |
|
|
-- this test executes and reports NOT_APPLICABLE
|
74 |
|
|
-- or
|
75 |
|
|
-- this test produces at least one error message at compilation, and
|
76 |
|
|
-- the error message is associated with one of the items marked:
|
77 |
|
|
-- -- N/A => ERROR.
|
78 |
|
|
--
|
79 |
|
|
-- All other behaviors are FAILING.

-- CHANGE HISTORY:
|
83 |
|
|
-- 11 JUL 95 SAIC Initial version
|
84 |
|
|
-- 10 MAR 97 PWB.CTA Made Nonstatic_Entity nonstatic; changed
|
85 |
|
|
-- Tenths'Small from 1.0/32.0 to 1.0/10.0,
|
86 |
|
|
-- as expected by the later check; improved
|
87 |
|
|
-- internal documentation.
|
88 |
|
|
-- 16 FEB 98 EDS Modified test documentation.
|
89 |
|
|
-- 24 NOV 98 RLB Changed Tenths'Small to 1.0/32.0, as this is
|
90 |
|
|
-- necessary so that all implementations can
|
91 |
|
|
-- process this test. (3.5.9(21) means non-binary
|
92 |
|
|
-- smalls are optional.)
|
93 |
|
|
-- 11 MAR 99 RLB Merged versions. Most EDS changes removed (as
|
94 |
|
|
-- they made the test less applicable than the ACAA
|
95 |
|
|
-- version).
