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.
