Properly handle Ada_Version_Explicit and Ada_Version_Config, which were not always properly handled previously. (Formal_Entity): Complete rewrite, to handle properly some complex case with multiple levels of parametrization by formal packages. (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator to the corresponding derived type declaration for proper semantics. * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message. (Check_Component): Enforce restriction on components of unchecked_unions: a component in a variant cannot contain tasks or controlled types. (Unchecked_Union): Allow nested variants and multiple discriminants, to conform to AI-216. Add pragma Ada_2005 (synonym for Ada_05) Properly handle Ada_Version_Explicit and Ada_Version_Config, which were not always properly handled previously. Document that pragma Propagate_Exceptions has no effect (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure (Set_Convention_From_Pragma): Check that if a convention is specified for a dispatching operation, then it must be consistent with the existing convention for the operation. (CPP_Class): Because of the C++ ABI compatibility, the programmer is no longer required to specify an vtable-ptr component in the record. For compatibility reasons we leave the support for the previous definition. (Analyze_Pragma, case No_Return): Allow multiple arguments * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a non-overrideen inherited operation with a controlling result as illegal only its implicit declaration comes from the derived type declaration of its result's type. (Check_Possible_Deferred_Completion): Relocate the object definition node of the subtype indication of a deferred constant completion rather than directly analyzing it. The analysis of the generated subtype will correctly decorate the GNAT tree. (Record_Type_Declaration): Check whether this is a declaration for a limited derived record before analyzing components. (Analyze_Component_Declaration): Diagnose record types not explicitly declared limited when a component has a limited type. (Build_Derived_Record_Type): Code reorganization to check if some of the inherited subprograms of a tagged type cover interface primitives. This check was missing in case of a full-type associated with a private type declaration. (Constant_Redeclaration): Check that the subtypes of the partial and the full view of a constrained deferred constant statically match. (Mentions_T): A reference to the current type in an anonymous access component declaration must be an entity name. (Make_Incomplete_Type_Declaration): If type is tagged, set type of class_wide type to refer to full type, not to the incomplete one. (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not available. Required to give support to the certified run-time. (Analyze_Component_Declaration): In case of anonymous access components perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2). (Process_Discriminants): For an access discriminant, use the discriminant specification as the associated_node_for_itype, to simplify accessibility checks. From-SVN: r111091
