+ (Freeze_Subprogram): Do nothing if we are compiling under full ABI
+ compatibility mode and we have an imported CPP subprogram because
+ for now we assume that imported CPP primitives correspond with

+ don't need to generate code to register them in the dispatch table).
+ (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
+ aligned selected component.
+ (Add_Call_By_Copy_Node): Add missing code to handle the case in which

+ to prevent anomalies in instantiations.
+ (Resolve_Aggregate): Remove test for limited components in aggregates.
+ It's unnecessary in Ada 95, because if it has limited components, then
+ it must be limited. It's wrong in Ada 2005, because limited aggregates
+ are now allowed.
+ (Resolve_Record_Aggregate): Move check for limited types later, because
+ OK_For_Limited_Init requires its argument to have been resolved.
+ (Get_Value): When copying the component default expression for a

+ and not that of the original expression, to prevent spurious
+ elaboration errors, when the expression includes function calls.

+ (Process_Subtype): If the subtype is a private subtype whose full view
+ is a concurrent subtype, introduce an itype reference to prevent scope

+ (Build_Derived_Record_Type, Collect_Interface_Primitives,
+ Record_Type_Declaration): The functionality of the subprograms
+ Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
+ is now performed by a single routine.
+ (Build_Derived_Record_Type): If the type definition includes an explicit
+ indication of limitedness, then the type must be marked as limited here
+ to ensure that any access discriminants will not be treated as having
+ a local anonymous access type.
+ (Check_Abstract_Overriding): Issue a detailed error message when an
+ abstract subprogram was not overridden due to incorrect mode of its
+ first parameter.
+ (Analyze_Private_Extension_Declaration): Add support for the analysis of
+ synchronized private extension declarations. Verify that the ancestor is
+ a limited or synchronized interface or in the generic case, the ancestor
+ is a tagged limited type or synchronized interface and all progenitors
+ are either limited or synchronized interfaces.
+ Derived_Type_Declaration): Check for presence of private extension when
+ dealing with synchronized formal derived types.

+ discriminants in the back-end.
+ (Collect_Implemented_Interfaces): Protect the recursive algorithm of
+ this subprogram against wrong sources.
+ (Get_Discr_Value, Is_Discriminant): Handle properly references to a
+ discriminant of limited type completed with a protected type, when the
+ discriminant is used to constrain a private component of the type, and
+ expansion is disabled.
+ (Find_Type_Of_Object): Do not treat a return subtype that is an
+ anonymous subtype as a local_anonymous_type, because its accessibility
+ level is the return type of the enclosing function.
+ (Check_Initialization): In -gnatg mode, turn the error "cannot
+ initialize entities of limited type" into a warning.
+ (OK_For_Limited_Init): Return true for generated nodes, since it
+ sometimes violates the legality rules.
+ (Make_Incomplete_Declaration): If the type for which an incomplete
+ declaration is created happens to be the currently visible entity,
+ preserve the homonym chain when removing it from visibility.
+ (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
+ inherited subprograms.
+ (Access_Definition): If this is an access to function that is the return
+ type of an access_to_function definition, context is a type declaration
+ and the scope of the anonymous type is the current one.
+ (Analyze_Subtype_Declaration): Add the defining identifier of a regular
+ incomplete subtype to the set of private dependents of the original
+ incomplete type.
+ (Constrain_Discriminated_Type): Emit an error message whenever an

+ (Analyze_Call): Add additional warnings for function call contexts not

+ (Analyze_Allocator): Move the check for "initialization not allowed for

+ were missing. We also didn't handle qualified expressions. Now also

+ (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
+ (Analyze_Overloaded_Selected_Component): Same change
+ (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
+ since regular incomplete subtypes are transformed into corresponding

+ (Complete_Object_Operation): Treat name of transformed subprogram call
+ as coming from source, for browsing purposes.
+ (Try_Primitive_Operation): If formal is an access parameter, compare

+ any order.
+ (Process_Full_View): The parent of the full-view does not need to be
+ a descendant of the parent of the partial view if both parents are
+ interfaces.
+ (Analyze_Private_Extension_Declaration): If declaration has an explicit
+ "limited" the parent must be a limited type.
+ (Build_Derived_Record_Type): A derived type that is explicitly limited
+ must have limited ancestor and progenitors.
+ (Build_Derived_Type): Ditto.
+ (Process_Full_View): Verify that explicit uses of "limited" in partial
+ and full declarations are consistent.
+ (Find_Ancestor_Interface): Remove function.
+ (Collect_Implemented_Interfaces): New procedure used to gather all
+ implemented interfaces by a type.
+ (Contain_Interface): New function used to check whether an interface is
+ present in a list.
+ (Find_Hidden_Interface): New function used to determine whether two
+ lists of interfaces constitute a set equality. If not, the first
+ differing interface is returned.
+ (Process_Full_View): Improve the check for the "no hidden interface"
+ rule as defined by AI-396.

+
+ * gnatcmd.adb (GNATCmd): GNAT CHECK accepts switch -U
+ If GNAT CHECK is called with a project file, but with no
+ source on the command line, call gnatcheck with all the compilable
+ sources of the project.
+ Take into account the new command Check, for gnatcheck. Treat as for
+ other ASIS tools: take into account project, specific package Check and
+ Compiler switches.
+ For ASIS tools, add the switches in package Compiler for
+ the invocation of the compiler.
+
+ * prj-attr.adb: Add package Check and its attributes
+
+ * vms_conv.ads (Command_Type): New command Check, for gnatcheck

+ ELIM.
+ Add qualifiers for Check command options
+ (Command_Type): New command Check

+
+ * sem_cat.adb (Validate_RCI_Subprogram_Declaration): Revise test for
+ available user-specified stream attributes on limited parameters to
+ also test the type directly rather than only its underlying type (for
+ Ada 95) and, in the case of Ada 2005, to check that the user-specified
+ attributes are visible at the point of the subprogram declaration.
+ For Ada 2005, the error message is modified to indicate that the
+ type's stream attributes must be visible (again, only for -gnat05).

+
+2005-12-09 Javier Miranda <miranda@adacore.com>
+
+ * sem_ch8.adb (Find_Type): In case of tagged types that are concurrent
+ types use the corresponding record type. This was not needed before
