|
|
|
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.
