--
-- OBJECTIVE:
-- Check that representation items may contain nonstatic expressions
-- in the case that each expression in the representation item is a
-- name that statically denotes a constant declared before the entity.
--
--
-- TEST DESCRIPTION:
-- For each of the specific items in the objective, this test checks
-- an example of each of the categories of representation specification
-- that are applicable to that objective, to wit:
-- address clause ....................... Expressions need not be static
-- alignment clause ..................... Expressions must be static
-- bit order clause ..................... Not tested
-- component size clause ................ Expressions must be static
-- enumeration representation clause .... Expressions must be static
-- external tag clause .................. Expressions must be static
-- Import, Export and Convention pragmas Not tested
-- input clause ......................... Not tested
-- output clause ........................ Not tested
-- Pack pragma .......................... Not tested
-- read clause .......................... Not tested
-- record representation clause ......... Expressions must be static
-- size clause .......................... Expressions must be static
-- small clause ......................... Expressions must be static
-- storage pool clause .................. Not tested
-- storage size clause .................. Expressions must be static
-- write clause ......................... Not tested
--
-- APPLICABILITY CRITERIA:
-- All implementations must attempt to compile this test.
--
-- For implementations validating against Systems Programming Annex (C):
-- this test must execute.
--
-- For implementations not validating against Annex C:
-- if this test compiles without error messages at compilation,
-- it must bind and execute.
--
-- PASS/FAIL CRITERIA:
-- For implementations validating against Systems Programming Annex (C):
-- this test must execute, report PASSED, and complete normally,
-- otherwise the test FAILS
--
-- For implementations not validating against Annex C:
-- PASSING behavior is:
-- this test executes, reports PASSED, and completes normally
-- or
-- this test executes and reports NOT_APPLICABLE
-- or
-- this test produces at least one error message at compilation, and
-- the error message is associated with one of the items marked:
-- -- N/A => ERROR.
--
-- All other behaviors are FAILING.
--
-- CHANGE HISTORY:
-- 11 JUL 95 SAIC Initial version
-- 10 MAR 97 PWB.CTA Made Nonstatic_Entity nonstatic; changed
-- Tenths'Small from 1.0/32.0 to 1.0/10.0,
-- as expected by the later check; improved
-- internal documentation.
-- 16 FEB 98 EDS Modified test documentation.
-- 24 NOV 98 RLB Changed Tenths'Small to 1.0/32.0, as this is
-- necessary so that all implementations can
-- process this test. (3.5.9(21) means non-binary
-- smalls are optional.)
-- 11 MAR 99 RLB Merged versions. Most EDS changes removed (as
-- they made the test less applicable than the ACAA
-- version).
