26
-- OBJECTIVE:
27
--
28
--
29
--      Check that the unspecified Size of static discrete
30
--      subtypes is the number of bits needed to represent each value
31
--      belonging to the subtype using an unbiased representation, where
32
--      space for a sign bit is provided only in the event the subtype
33
--      contains negative values.  Check that for first subtypes specified
34
--      Sizes are supported reflecting this representation. [ARM 95 13.3(55)].
35
--
36
-- TEST DESCRIPTION:
37
--      This test defines a few types that should have distinctly recognizable
38
--      sizes.  A packed record which should result in very specific bits
39
--      sizes for it's components is used to check the first part of the
40
--      objective. The second part of the objective is checked by giving
41
--      sizes for a similar set of types.
42
--
43
-- APPLICABILITY CRITERIA:
44
--      All implementations must attempt to compile this test.
45
--
46
--      For implementations validating against Systems Programming Annex (C):
47
--        this test must execute and report PASSED.
48
--
49
--      For implementations not validating against Annex C:
50
--        this test may report compile time errors at one or more points
51
--        indicated by "-- ANX-C RQMT", in which case it may be graded as inapplicable.
52
--        Otherwise, the test must execute and report PASSED.
53
--
54
-- CHANGE HISTORY:
55
--      22 JUL 95   SAIC   Initial version
56
--      06 MAY 96   SAIC   Revised for 2.1
57
--      26 FEB 97   PWB.CTA Added pragma Pack for type Check_Record
58
--      16 FEB 98   EDS    Modified Documentation.
59
--      06 JUL 99   RLB    Repaired comments, removed junk test cases.
60
--                         Added test cases to test that appropriate Size
61
--                         clauses are allowed.
