Otherwise, the test must execute and report PASSED. -- -- -- CHANGE HISTORY: -- 22 JUL 95 SAIC Initial version -- 08 MAY 96 SAIC Strengthened for 2.1 -- 29 JAN 98 EDS Deleted check that Component_Size is really a -- factor of Word_Size. --! ----------------------------------------------------------------- CD20001_0 with System; package CD20001_0 is type Wordlong_Bool_Array is array(1..System.Word_Size) of Boolean; pragma Pack(Wordlong_Bool_Array); -- ANX-C RQMT type Def_Rep_Components is range 0..2**(System.Storage_Unit-2); type Spec_Rep_Components is range 0..2**(System.Storage_Unit-2); for Spec_Rep_Components'Size use System.Storage_Unit; -- ANX-C RQMT type Packed_Array_Def_Components is array(1..32) of Def_Rep_Components; pragma Pack(Packed_Array_Def_Components); -- ANX-C RQMT type Packed_Array_Spec_Components is array(1..32) of Spec_Rep_Components; pragma Pack(Packed_Array_Spec_Components); -- ANX-C RQMT procedure TC_Check_Values; end CD20001_0; -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- with Report; with TCTouch; package body CD20001_0 is procedure TC_Check_Values is My_Word : Wordlong_Bool_Array := (others => False); Cited_Unit : Spec_Rep_Components := 0; Packed_Array : Packed_Array_Def_Components := (others => 0); Cited_Packed : Packed_Array_Spec_Components := (others => 0); begin TCTouch.Assert( My_Word'Size = System.Word_Size, "pragma Pack on array of Booleans does not pack one Boolean per bit" ); TCTouch.Assert( My_Word'Component_Size = 1, "size of Boolean array component not 1 bit"); TCTouch.Assert( Cited_Unit'Size = System.Storage_Unit, "Object specified to be Storage_Unit bits not " & "Storage_Unit bits in size"); TCTouch.Assert( Packed_Array'Component_Size <= System.Storage_Unit, "Packed array component expected to be less than or " & "equal to Storage_Unit bits in size is greater than " & "Storage_Unit bits in size"); TCTouch.Assert( Cited_Packed'Component_Size = System.Storage_Unit, "Array component specified to be Storage_Unit " & "bits not Storage_Unit bits in size"); end TC_Check_Values; end CD20001_0; ----------------------------------------------------------------- CD20001_1 with System; package CD20001_1 is type Bits_2 is range 0..2**2-1; for Bits_2'Size use 2; -- ANX-C RQMT type Bits_3 is range 0..2**3-1; for Bits_3'Size use 3; -- ANX-C RQMT type Bits_7 is range 0..2**7-1; for Bits_7'Size use 7; -- ANX-C RQMT type Bits_8 is range 0..2**8-1; for Bits_8'Size use 8; -- ANX-C RQMT type Bits_9 is range 0..2**9-1; for Bits_9'Size use 9; -- ANX-C RQMT type Bits_15 is range 0..2**15-1; for Bits_15'Size use 15; -- ANX-C RQMT type Pact_Aray_2 is array(0..31) of Bits_2; pragma Pack( Pact_Aray_2 ); -- ANX-C RQMT type Pact_Aray_3 is array(0..31) of Bits_3; pragma Pack( Pact_Aray_3 ); -- ANX-C RQMT type Pact_Aray_7 is array(0..31) of Bits_7; pragma Pack( Pact_Aray_7 ); -- ANX-C RQMT type Pact_Aray_8 is array(0..31) of Bits_8; pragma Pack( Pact_Aray_8 ); -- ANX-C RQMT type Pact_Aray_9 is array(0..31) of Bits_9; pragma Pack( Pact_Aray_9 ); -- ANX-C RQMT type Pact_Aray_15 is array(0..31) of Bits_15; pragma Pack( Pact_Aray_15 ); -- ANX-C RQMT procedure TC_Check_Values; end CD20001_1; -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- with Report; with TCTouch; package body CD20001_1 is function Next_Factor ( Value : Positive ) return Integer is -- Returns the factor of Word_Size that is next larger than Value. -- If Value is greater than Word_Size, then returns Word_Size.
