It then checks the alignments by --- declaring some objects, and checking that the integer values of --- their addresses is mod the specified alignment. This will not --- prevent false passes where the lucky compiler gets it right by --- chance, but will catch compilers that specifically do not obey --- the alignment clauses. --- --- APPLICABILITY CRITERIA: --- All implementations must attempt to compile this test. --- --- For implementations validating against Systems Programming Annex (C): --- this test must execute and report PASSED. --- --- For implementations not validating against Annex C: --- this test may report compile time errors at one or more points --- indicated by "-- ANX-C RQMT", in which case it may be graded as inapplicable. --- Otherwise, the test must execute and report PASSED. --- --- --- CHANGE HISTORY: --- 22 JUL 95 SAIC Initial version --- 09 MAY 96 SAIC Strengthened for 2.1 --- 26 FEB 97 PWB.CTA Allowed for unexpected word sizes --- 16 FEB 98 EDS Modified documentation. --- 26 SEP 98 RLB Fixed value on line 130 so check and dec. match. --- 30 OCT 98 RLB Split Multiple_Alignment and revised the --- calculation to work on all targets. --- 18 JAN 99 RLB Repaired again to work on targets where word size --- equals storage unit. ---! - ------------------------------------------------------------------ CD30002_0 - -with Impdef; -with System.Storage_Elements; -package CD30002_0 is - - S_Units_per_Word : constant := System.Word_Size/System.Storage_Unit; - -- Must be 1 or greater. - - Multiple_Type_Alignment : constant := - Integer'Min ( Impdef.Max_Default_Alignment, - 2 * S_Units_per_Word ); - -- Calculate a reasonable alignment, but not larger than the - -- implementation is required to support. - - Multiple_Object_Alignment : constant := - Integer'Min ( Impdef.Max_Linker_Alignment, - 2 * S_Units_per_Word ); - -- Calculate a reasonable object alignment, but not larger than - -- the implementation is required to support. - - Small_Alignment : constant := - Integer'Max ( S_Units_per_Word / 2, 1); - -- Calculate a reasonable small alignment, but not less than 1. - -- (If S_Units_per_Word = 1, 1/2 => 0 which causes problems - -- verifying alignment.) - - subtype Storage_Element is System.Storage_Elements.Storage_Element; - - type Some_Stuff is array(1..S_Units_Per_Word) of Storage_Element; - for Some_Stuff'Alignment - use Impdef.Max_Default_Alignment; -- ANX-C RQMT. - - Library_Level_Object : Some_Stuff; - for Library_Level_Object'Alignment - use Impdef.Max_Linker_Alignment; -- ANX-C RQMT. - - type Quarter is mod 4; -- two bits - for Quarter'Alignment use Small_Alignment; -- ANX-C RQMT. - - type Half is mod 16; -- nibble - for Half'Alignment use Multiple_Type_Alignment; -- ANX-C RQMT. - - type O_Some_Stuff is array(1..S_Units_Per_Word) of Storage_Element; - - type O_Quarter is mod 4; -- two bits - - type O_Half is mod 16; -- nibble - -end CD30002_0; - --- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- - --- there is no package body CD30002_0 - -------------------------------------------------------------------- CD30002 - -with Report; -with Impdef; -with CD30002_0; -with System.Storage_Elements; -procedure CD30002 is - - My_Stuff : CD30002_0.Some_Stuff; - -- Impdef.Max_Default_Alignment - - My_Quarter : CD30002_0.Quarter; - -- CD30002_0.S_Units_per_Word / 2 - - My_Half : CD30002_0.Half; - -- CD30002_0.S_Units_per_Word * 2 - - Stuff_Object : CD30002_0.O_Some_Stuff; - for Stuff_Object'Alignment - use Impdef.Max_Default_Alignment; -- ANX-C RQMT. - - Quarter_Object : CD30002_0.O_Quarter; - for Quarter_Object'Alignment - use CD30002_0.Small_Alignment; -- ANX-C RQMT. - - Half_Object : CD30002_0.O_Half; - for Half_Object'Alignment - use CD30002_0.Multiple_Object_Alignment; -- ANX-C RQMT. - - subtype IntAdd is System.Storage_Elements.Integer_Address; - use type System.Storage_Elements.Integer_Address; - - function A2I(Value: System.Address) return IntAdd renames - System.Storage_Elements.To_Integer; - - NAC : constant String := " not aligned correctly"; - -begin -- Main test procedure. - - Report.Test ("CD30002", "Check that the implementation supports " & - "Alignments for subtypes and objects specified " & - "as factors and multiples of the number of " & - "storage elements per word, unless those values " & - "cannot be loaded and stored.
