2005-09-01 Javier Miranda <miranda@adacore.com> Gary Dismukes <dismukes@adacore.com> * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous access types the null-exclusion and access-to-constant attributes must also match. (Analyze_Return_Statement): When the result type is an anonymous access type, apply a conversion of the return expression to the access type to ensure that appropriate accessibility checks are performed. (Analyze_Return_Type): For the case of an anonymous access result type, generate the Itype and set Is_Local_Anonymous_Access on the type. Add ??? placeholder for check to disallow returning a limited object in Ada 2005 unless it's an aggregate or a result of a function call. Change calls from Subtype_Mark to Result_Definition. (Analyze_Subprogram_Body): Change formal Subtype_Mark to Result_Definition in call to Make_Function_Specification. (Build_Body_To_Inline): Change Set_Subtype_Mark to Set_Result_Definition. (Make_Inequality_Operator): Change formal Subtype_Mark to Result_Definition in call to Make_Function_Specification. (Process_Formals): Create the new null-excluding itype if required. (New_Overloaded_Entity): For an entity overriding an interface primitive check if the entity also covers other abstract subprograms in the same scope. This is required to handle the general case, that is, overriding other interface primitives and overriding abstract subprograms inherited from some abstract ancestor type. (New_Overloaded_Entity): For an overriding entity that comes from source, note the operation that it overrides. (Check_Conformance, Type_Conformant): Addition of one new formal to skip controlling formals in the analysis. This is used to handle overloading of abstract interfaces. (Base_Types_Match): Add missing case for types imported from limited-with clauses (New_Overloaded_Entity): Add barrier to protect the use of the "alias" attribute. From-SVN: r103883
