Check that multiple --- compilation units are affected. Check for uninitialized scalar --- objects that are subcomponents of composite objects, unassigned --- out parameters, objects that have been allocated without an initial --- value, and objects that are stand alone. --- --- TEST DESCRIPTION --- The test requires that the configuration pragma Normalize_Scalars --- be processed. It then defines a few scalar types (some enumeration, --- some integer) in a few packages. The scalar types are designed such --- that the representation will easily allow for an out of range value. --- Unchecked_Conversion and the 'Valid attribute are both used to verify --- that the default values of the various kinds of objects are indeed --- invalid for the type. --- --- Note that this test relies on having uninitialized objects, compilers --- may generate several warnings to this effect. --- --- SPECIAL REQUIREMENTS --- The implementation must process configuration pragmas which --- are not part of any Compilation Unit; the method employed --- is implementation defined. --- --- APPLICABILITY CRITERIA: --- This test is only applicable for a compiler attempting validation --- for the Safety and Security Annex. --- --- --- CHANGE HISTORY: --- 26 OCT 95 SAIC Initial version --- 04 NOV 96 SAIC Added cases, upgraded commentary --- ---! - ----------------------------- CONFIGURATION PRAGMAS ----------------------- - -pragma Normalize_Scalars; -- OK - -- configuration pragma - ------------------------- END OF CONFIGURATION PRAGMAS -------------------- - - ------------------------------------------------------------------ CXH1001_0 - -with Impdef.Annex_H; -with Unchecked_Conversion; -package CXH1001_0 is - - package Imp_H renames Impdef.Annex_H; - use type Imp_H.Small_Number; - use type Imp_H.Scalar_To_Normalize; - - Global_Object : Imp_H.Scalar_To_Normalize; - -- if the pragma is in effect, this should come up with the predictable - -- value - - Global_Number : Imp_H.Small_Number; - -- if the pragma is in effect, this should come up with the predictable - -- value - - procedure Package_Check; - - type Num is range 0..2**Imp_H.Scalar_To_Normalize'Size-1; - for Num'Size use Imp_H.Scalar_To_Normalize'Size; - - function STN_2_Num is - new Unchecked_Conversion( Imp_H.Scalar_To_Normalize, Num ); - - Small_Last : constant Integer := Integer(Imp_H.Small_Number'Last); - -end CXH1001_0; - --- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- - -with Report; -package body CXH1001_0 is - - procedure Heap_Check( A_Value : access Imp_H.Scalar_To_Normalize; - A_Number : access Imp_H.Small_Number ) is - Value : Num; - Number : Integer; - begin - - if A_Value.all'Valid then - Value := STN_2_Num ( A_Value.all ); - if Imp_H.Default_For_Scalar_To_Normalize_Is_In_Range then - if Imp_H.Scalar_To_Normalize'Val(Value) - /= Imp_H.Default_For_Scalar_To_Normalize then - Report.Failed("Implicit initial value for local variable is not " - & "the predicted value"); - end if; - else - if Value in 0 .. - Imp_H.Scalar_To_Normalize'Pos(Imp_H.Scalar_To_Normalize'Last) then - Report.Failed("Implicit initial value for local variable is a " - & "value of the type"); - end if; - end if; - end if; - - if A_Number.all'Valid then - Number := Integer( A_Number.all ); - if Imp_H.Default_For_Small_Number_Is_In_Range then - if Global_Number /= Imp_H.Default_For_Small_Number then - Report.Failed("Implicit initial value for number is not " - & "the predicted value"); - end if; - else - if Integer( Global_Number ) in 0 ..
