26
-- OBJECTIVE:
27
--      Check that Component_Sizes that are multiples of the word
28
--      size are supported.
29
--
30
--      Check that for such Component_Sizes arrays contain no gaps between
31
--      components.
32
--
33
-- TEST DESCRIPTION:
34
--      This test defines three array types and specifies their layouts
35
--      using representation specifications for the 'Component_Size and
36
--      pragma Packs for each.  It then checks that the implied assumptions
37
--      about the resulting layout actually can be made.
38
--
39
-- APPLICABILITY CRITERIA:
40
--      All implementations must attempt to compile this test.
41
--
42
--      For implementations validating against Systems Programming Annex (C):
43
--        this test must execute and report PASSED.
44
--
45
--      For implementations not validating against Annex C:
46
--        this test may report compile time errors at one or more points
47
--        indicated by "-- ANX-C RQMT", in which case it may be graded as inapplicable.
48
--        Otherwise, the test must execute and report PASSED.

51
-- CHANGE HISTORY:
52
--      22 JUL 95   SAIC   Initial version
53
--      07 MAY 96   SAIC   Revised for 2.1
54
--      24 AUG 96   SAIC   Additional 2.1 revisions
