        * a-tags.adb: 
        (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
         indirection added to the HT_Link component of the TSD. This is required
         to statically allocate the TSD.

        * a-tags.ads: 
        Minor reordering of the declarations in the private part. Required to
        add a level of indirection to the contents of the TSD component HT_Link.
        This is required to statically allocate the TSD.

        * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
        Is_Statically_Allocated set from constant objects.
        Do not make exported constants created by the compiler volatile.

        before returning them.

        * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the

        (Make_DT): Move HT_Link component out of the TSD record. For this
        purpose Make_DT now declares a separate object that stores the
        HT_Link value, and initializes the TSD component with the address
        of this new object. The addition of this level of indirection is
        required to statically allocate the TSD because the TSD cannot
        have variable components.
        (Expand_Interface_Conversion): Improve the expanded code.
        (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.

        * sem_disp.adb (Check_Dispatching_Operation): In case of a body
        declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
        if we are building static dispatch tables then we must not generate
        extra code to register the primitive because the dispatch table will
        be built at the end of the library package; otherwise we notify that
        we cannot build the static dispatch table.

        level of the access type actuals.

        * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field

        (Uninstall_Declarations): If entity is a use-visible compilation unit,
        its child units are use-visible only if they are visible child units.

        * sem_util.adb (Is_Preelaborable_Expression): New function to determine
        whether an expression can be used within a type declaration that
        requires preelaborable init.
        (Check_Components): Replace inline code that does partial checking for
        preelaborable default expressions with call to
        Is_Preelaborable_Expression.
        (Has_Preelaborable_Initialization): In the case of a generic actual
        subtype, (that is, Is_Generic_Actual is True), return the result of
        applying Has_Preelaborable_Initialization to the generic actual's base
        type.

        implementation.

        * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
        Command_Line): New types
        (Define_Alias, Define_Prefix, Free): New subprograms. These provide
        support for defining how switches can be grouped on a command line (as
        is the case for -gnatw... for GNAT), and how simple switches can be
        used as aliases for more complex switches (-gnatwa is same as
        -gnatwbcef...)
        (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
        (Start, Current_*): New subprograms
        Added support for parsing an array of strings in addition to the real
        command line.
        (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
         be moved from the body to the private part of the spec.
        (*): All subprograms now have an extra parameter with default value to
        specify which parser should be used. For backward compatibility, it
        defaults to parsing the command line of the application. They were also
        modified to properly handle cases where each of the argument does not
        start at index 1 (which is always true for Ada.Command_Line, but not
        when processing any Argument_List).
        (Free): New subprogram
        (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
        Argument): New subprograms
        (Switch_Parameter_Type): New enum, which clarifies the code. The extra
        special characters like ':', '=',... are now handled in a single place,
        which makes the code more extensible eventually.
        (Getopt, Full_Switch): When the switch was returned as part of the
        special character '*', make sure it is prepended by the switch character
        ('-' in general), so that the application knows whether "foo" or "-foo"
        was specified on the command line.

2007-09-26  Florian Villoing  <villoing@adacore.com>

        * g-dirope.adb (Remove_Dir): In case we are removing directories
        recursively, make sure that if an exception is raised during the

        value before propagating the exception.

        from the first ALI file name.

        being extended, instead of a shallow copy.

            Thomas Quinot  <quinot@adacore.com>

        * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
        create an abstract subprogram in the case of 'Input. For 'Output we now
        create a real spec/body when the type is abstract, since it can
        potentially be called.
        (Predefined_Primitive_Bodies): Now allow the creation of a predefined
        body for 'Output when the type is abstract (only the creation of the
        body for 'Input is excluded when the type is abstract).
        (Stream_Operation_OK): Add an additional condition in the return
        statement, so that False will be returned for TTS_Stream_Input if the
        associated tagged type is an abstract extension. Add comments for
        return statement.
        (Expand_N_Object_Declaration): For the case of a shared passive
        variable, insert init proc call only after the shared variable
        procedures have been processed, because the IP call needs to undergo
        shared passive variable reference expansion, which requires these
        procedures to be available (and elaborated).

        and the value of the discriminant is the discriminant of the enclosing
        type, retrieve its value from the aggregate itself, where it must have
        been supplied.

        * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
        to remove other spurious ambiguities on arithmetic operations involving
        literals and addresses, on systems where Address is a visible integer
        type, when the operator is called in functional notation.
        (Try_Primitive_Operation): Within an instance, a call in prefixed form
        is legal when the types match, even if the operation is currently
        hidden.

        components that are access type with an allocator as default value: add
        missing support to the use of qualified expressions of the
        allocator (which also cause freezing of the designated type!)
        (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
        dispatching operation, since extra formals may be needed by calls to
        build-in-place functions (such as stream 'Input).

        * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
        formals for 'Constrained and accessibility level in the case of a

        parameters when deciding whether to apply a run-time accessibility
        check.
        (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
        aggregate code before allocator, and ahead of declaration for
        temporary, to prevent access before elaboration when the allocator is
        an actual for an access parameter.
        (Expand_N_Type_Conversion): On an access type conversion involving an
        access parameter, do not apply an accessibility check when the
        operand's original node was an attribute other than 'Access. We now
        create access conversions for the expansion of 'Unchecked_Access and
        'Unrestricted_Access in certain cases and clearly accessibility should
        not be checked for those.

        * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
        includes a type conversion of a packed component that has been expanded,
        recover the original expression for the object, and use this expression
        in the post-call assignment statement, so that the assignment is made
        to the object and not to a back-end temporary.
        (Freeze_Subprogram): In case of primitives of tagged types not defined
        at the library level force generation of code to register the primitive
        in the dispatch table. In addition some code reorganization has been
        done to leave the implementation clear.
        (Expand_Call): When expanding an inherited implicit conversion,
        preserve the type of the inherited function after the intrinsic
        operation has been expanded.

        * exp_ch2.ads, exp_ch2.adb
        (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
        of an entry formal appearing in an assignment statement does not assign
        to the formal.
        (Expand_Current_Value): Instead of calling a routine to determine
        whether the prefix of an attribute reference should be optimized or
        not, prevent the optimization of such prefixes all together.

        * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
        component whose prefix is known to be of an access type is an implicit
        dereference and does not assign to the prefix.

        * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
        itype is visited, make an entry into table to link associated node and
        new itype.
        Add comments and correct harmless error in Build_NCT_Hash_Tables
        (Array_Aggr_Subtype): Associate each itype created for an index type to
        the corresponding range construct, and not to the aggregate itself. to
        maintain a one-to-one correspondence between itype and its associated
        node, to prevent errors when complex expression is copied.
        Fix mishandling of multiple levels of parens

        * sem_aggr.adb: Create a limited view of an incomplete type, to make
        treatment of limited views uniform for all visible declarations in a
        limited_withed package.
        (New_Copy_Tree): If hash table is being used and itype is visited,
        make an entry into table to link associated node and new itype.
        (Resolve_Record_Aggregate): Do not add an others box association for a
        discriminated record component that has only discriminants, when there
        is a box association for the component itself.

        * par-ch4.adb: Fix mishandling of multiple levels of parens

        excluding access types in the backend.
        (Create_Extra_Formals): Test base type of the formal when checking for
        the need to add an extra accessibility-level formal. Pass the entity E
        on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
        originally being done in a couple of cases), to ensure that the
        Extra_Formals list gets set on the entity E when the first entity is
        added.
        (Conforming_Types): Add missing calls to Base_Type to the code that
        handles anonymous access types. This is required to handle the
        general case because Process_Formals builds internal subtype entities
        to handle null-excluding access types.
        (Make_Controlling_Function_Wrappers): Create wrappers for constructor
        functions that need it, even when not marked Requires_Overriding.

        (Check_Overriding_Indicator): Add in parameter Is_Primitive.
        (Analyze_Function_Return): Move call to Apply_Constraint_Check before
        the implicit conversion of the expression done for anonymous access
        types. This is required to generate the code of the null excluding
        check (if required).

        * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
        A formal parameter is never publicly referenceable outside of its body.
        (Check_References): For an unreferenced formal parameter in an accept
        statement, use the same warning circuitry as for subprogram formal
        parameters.
        (Warn_On_Unreferenced_Entity): New subprogram, taken from
        Output_Unreferenced_Messages, containing the part of that routine that
        is now reused for entry formals as described above.
        (Goto_Spec_Entity): New function
        (Check_References): Do not give IN OUT warning for dispatching operation
        Improve warnings for in out parameters
        (Test_Ref): Check that the entity is not undefinite before calling
        Scope_Within, in order to avoid infinite loops.
        Warn on return from procedure with unset out parameter
        Improved warnings for unused variables

        * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
        (Expand_N_Attribute_Reference): Further unify the handling of the
        three forms of access attributes, using common code now for all three
        cases. Add a test for the case of applying an access attribute to
        an explicit dereference when the context is an access-to-interface
        type. In that case we need to apply the conversion to the prefix
        of the explicit dereference rather than the prefix of the attribute.
        (Attribute_Version, UET_Address): Set entity as internal to ensure
        proper dg output of implicit importation.
        (Expand_Access_To_Type): Removed.
        (Expand_N_Attribute_Reference): Merge the code from the three cases
        of access attributes, since the processing is largely identical for
        these cases. The substantive fix here is to process the case of a
        type name prefix (current instance case) before handling the case
        of interface prefixes.

        (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
        type that is an anonymous access to controlled object, establish
        an associated finalization chain to avoid corrupting the global
        finalization list when a dynamically allocated object designated
        by such a component is deallocated.
        (Make_Controlling_Function_Wrappers): Create wrappers for constructor
        functions that need it, even when not marked Requires_Overriding.
        (Initialize_Tag): Replace call to has_discriminants by call to
        Is_Variable_Size_Record in the circuitry that handles the
        initialization of secondary tags.
        (Is_Variable_Size_Record): New implementation.
        (Expand_N_Object_Declaration): Suppress call to init proc if there is a
        Suppress_Initialization pragma for a derived type.
        (Is_Variable_Size_Record): New subprogram.
        (Build_Offset_To_Top_Functions): New implementation that simplifies the
        initial version of this routine and also fixes problems causing
        incomplete initialization of the table of interfaces.
        (Build_Init_Procedure): Improve the generation of code to initialize the
        the tag components of secondary dispatch tables.
        (Init_Secondary_Tags): New implementation that simplifies the previous
        version of this routine.
        (Make_DT): Add parameter to indicate when type has been frozen by an
        object declaration, for diagnostic purposes.
        (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
        diagnose attemps to freeze a subprogram when some untagged type of its
        profile is a private type whose full view has not been analyzed yet.
        (Freeze_Array_Type): Generate init proc for packed array if either
        Initialize or Normalize_Scalars is set.
        (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
        constructing the new profile, copy the null_exclusion indicator for each
        parameter, to ensure full conformance of the new body with the spec.

        * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
        Create wrappers for constructor functions that need it, even when not
        marked Requires_Overriding.
        (Covers): Handle properly designated types of anonymous access types,
        whose non-limited views are themselves incomplete types.
        (Add_Entry): Use an entity to store the abstract operation which hides
        an interpretation.
        (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
        (Collect_Interps): Use Empty as an actual for Abstract_Op in the

        operator.
        (Binary_Op_Interp_May_Be_Hidden): New routine.
        (Collect_Interps): Add value for flag May_Be_Hidden in initialization
        aggregate.

        of the same dispatch table slot to renamed primitives.
        (Make_Select_Specific_Data_Table): Handle private types.
        (Tagged_Kind): Handle private types.
        (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
        output of implicit importation and exportation.
        (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
        first formal of the thunk is always associated with the controlling
        type. In addition perform the following code cleanup: remove formal
        Thunk_Alias which is no longer required, cleanup evaluation of the
        the controlling type, and update the documentation.
        Replace occurrence of Default_Prim_Op_Count by
        Max_Predef_Prims. Addition of compile-time check to verify
        that the value of Max_Predef_Prims is correct.
        (Check_Premature_Freezing): Apply check in Ada95 mode as well.
        (Make_DT): Add parameter to indicate when type has been frozen by an
        object declaration, for diagnostic purposes.
        (Build_Static_Dispatch_Tables): New subprogram that takes care of the
        construction of statically allocated dispatch tables.
        (Make_DT): In case of library-level tagged types export the declaration
        of the primary tag. Remove generation of tags (now done by Make_Tags).
        Additional modifications to handle non-static generation of dispatch
        tables. Take care of building tables for asynchronous interface types
        (Make_Tags): New subprogram that generates the entities associated with
        the primary and secondary tags of Typ and fills the contents of Access_
        Disp_Table. In case of library-level tagged types imports the forward
        declaration of the primary tag that will be declared later by Make_DT.
        (Expand_Interface_Conversion): In case of access types to interfaces
        replace an itype declaration by an explicit type declaration to avoid
        problems associated with the scope of such itype in transient blocks.

            Javier Miranda  <miranda@adacore.com>

        * exp_util.ads, exp_util.adb: 
        This patch replaces a number of occurrences of explicit tests for N_Null
        with calls to Known_Null. This improves tracking of null values, since
        Known_Null also catches null constants, and variables currently known to
        be null, so we get better tracking.
        (Ensure_Defined): create an itype reference only in the scope of the
        itype.
        (Side_Effect_Free): A selected component of an access type that
        denotes a component with a rep clause must be treated as not
        side-effect free, because if it is part of a linked structure its
        value may be affected by a renaming.
        (Expand_Subtype_From_Expr): For limited objects initialized with build
        in place function calls, do nothing; otherwise we prematurely introduce
        an N_Reference node in the expression initializing the object, which
        breaks the circuitry that detects and adds the additional arguments to
        the called function. Bug found working in the new patch for statically
        allocated dispatch tables.
        (Is_Library_Level_Tagged_Type): New subprogram.
        (Remove_Side_Effects): If the expression of an elementary type is an
        operator treat as a function call.
        (Make_Literal_Range): If the index type of the array is not integer, use
        attributes properly to compute the constraint on the resulting aggregate
        which is a string.

        * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
        class-wide type whose base type is an incomplete private type, leave
        class-wide type unfrozen so that freeze nodes can be generated
        properly at a later point.
        (Freeze_Entity, array case): Handle case of pragma Pack and component
        size attributre clause for same array.

            Thomas Quinot  <quinot@adacore.com>

        * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
        derived type with interface progenitors use the analyzed formal as the
        parent of the actual, to create renamings for all the inherited
        operations in Derive_Subprograms.
        (Collect_Previous_Instances): new procedure within of
        Load_Parent_Of_Generic, to instantiate all bodies in the compilation
        unit being loaded, to ensure that the generation of global symbols is
        consistent in different compilation modes.
        (Is_Tagged_Ancestor): New function testing the ancestor relation that
        takes progenitor types into account.
        (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
        traversing over the primitives of the formal and actual types to locate
        any abstract subprograms of the actual type that correspond to a
        nonabstract subprogram of the formal type's ancestor type(s), and issue
        an error if such is found.
        (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
        Instantiate_Package_Body, Instantiate_Subprogram_Body):
        Remove bogus guard around calls to Inherit_Context.
        (Reset_Entity): If the entity is the selector of a selected component
        that denotes a named number, propagate constant-folding to the generic
        template only if the named number is global to the generic unit.
        (Set_Instance_Env): Only reset the compilation switches when compiling
        a predefined or internal unit.

2007-08-14  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
        parameter to determine whether operation applies to the prefix.
        (Complete_Object_Operation): If actual has an access type and
        controlling formal is not an in_parameter, reject the actual if it is
        an access_to_constant type.
        (Try_Primitive_Operation): If the type of the prefix is a formal tagged
        type, the candidate operations are found in the scope of declaration of
        the type, because the type has no primitive subprograms.
        (Analyze_Selected_Component): If prefix is class-wide, and root type is
        a private extension, only examine visible components before trying to
        analyze as a prefixed call.
        Change Entity_List to Type_To_Use, for better readability.
        (Has_Fixed_Op): Use base type when checking whether the type of an
        operator has a user-defined multiplication/division

        * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
        formal At_Any_Place indicating, when True, that we want to test for
        availability of the stream attribute at any place (as opposed to the
        current visibility context only).
        (Missing_Read_Write_Attributes): A stream attribute is missing for the
        purpose of enforcing E.2.2(8) only if it is not available at any place.
        Take into account the Ada2005 pragma Has_Preelaborable_Initialization
        when checking the legality of an extension aggregate in a preelaborable
        package. Treat the literal null as a valid default expression in a
        component declaration for a type with preelaborable initialization.
        A limited interface is a legal progenitor for the designated type of a
        remote access to class-wide type.

        setting the Referenced_As_LHS flag for entities that are implicitly
        dereferenced.
        (Find_Type): If the type is an internally generated incomplete type,
        mark the full view as referenced, to prevent spurious warnings.
        (Find_Selected_Component, Has_Components): Handle properly non-limited
        views that are themselves incomplete types.
        Handle interfaces visible through limited-with clauses.
        (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
        subprogram generic actual for which we have generated a renaming.
        Warn when the renaming introduces a homonym of
        the renamed entity, and the renamed entity is directly visible.

        coextension.
        (Resolve_Allocator): Perform cleanup if resolution has determined that
        the allocator is not a coextension.
        (Resolve): Skip an interpretation hidden by an abstract operator only
        when the type of the interpretation matches that of the context.
        (Resolve): When looping through all possible interpretations of a node,
        do not consider those that are hidden by abstract operators.
        (Resolve_Actuals): When verifying that an access to class-wide object
        is an actual  for a controlling formal, ignore anonymous access to
        subprograms whose return type is an access to class_wide type.
        (Resolve_Slice): If the prefix of the slice is a selected component
        whose type depends on discriminants, build its actual subtype before
        applying range checks on the bounds of the slice.
        (Valid_Conversion): In an instance or inlined body, compare root types,
        to prevent anomalies between private and public views.
        (Resolve): Improve error message for ambiguous fixed multiplication
        expressions that involve universal_fixed multiplying operations.

        elabration statements, register the package with the name server
        at the beginning, not at the end, of the elaboration statements so
        that they can create remote access to subprogram values that designate
        remote subprograms from the package.

2007-08-14  Hristian Kirtchev  <kirtchev@adacore.com>

        * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
        values to compute the number of seconds since the Unix Epoc in order to
        account for Daylight Savings Time. Perform special processing for dates
        that are earlier than the Unix Epoc to obtain a negative number.

        * lib-load.adb (From_Limited_With_Chain): Always scan the stack of
        units being loaded to detect circularities. A circularity may be
        present even if the current chain of pending units to load starts from
        a limited_with_clause.

        * lib-load.ads: Change profile of Load_Unit to use a with_clause
        rather than a boolean flag, in order to detect circularities in
        with_clauses.

        * par-load.adb: Use current with_clause in calls to Load_Unit, rather
        than propagating the From_Limited_With flag, in order to handle

        Add s-osinte-vxworks-kernel.adb to the target pairs of the
        kernel run-time lib for VxWorks 6, which would provide a different
        implementation for Task_Cont and Task_Stop than the VxWorks 5 version.
        x86-solaris section (EH_MECHANISM): Set to -gcc, as this port is now
        running ZCX by default.
        Add g-sttsne-locking to LynxOS version.
