* sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
that Scope_Stack.First = 1.
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.
