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.
