        * exp_ch6.adb (Expand_Inlined_Call): Handle properly the case
        where the return type is an unconstrained array and the context
        is an assignment. Optimize the case when the target of the
        assignment is a selected component.

        (Nearest_Multiple_Rounded_Up): New routine.
        (Size_Of): Update comment on usage. The generated expression now
        accounts for alignment gaps by rounding the size of the type to the

        (Expand_Call.Add_Actual_Parameter): Fix a bug in the
        case where the Parameter_Associatiations attribute is already set,
        but set to an empty list.
        (Needs_Result_Accessibility_Level):
        Unconditionally return False. This is a temporary
        change, disabling the Extra_Accessibility_Of_Result
        mechanism.
        (Expand_Simple_Function_Return): Check for
        Extra_Accessibility_Of_Result parameter's presence instead of
        testing Ada_Version when generating a runtime accessibility
        check which makes use of the parameter.

2011-09-06  Ed Schonberg  <schonberg@adacore.com>

        * exp_ch4.adb (Expand_N_Case_Expression): Actions created for the
        expression in a given case alternative must be attached to the
        statement list of the ccrresponding case statement alternative
        They cannot be propagated ahead of the case statement, because
        the validity of the expression that generated the action may
        hold only for that alternative.

2011-09-06  Hristian Kirtchev  <kirtchev@adacore.com>

        calculation of the dope's size.  Update relevant comments.
        (Size_Of): New routine.

2011-09-06  Steve Baird  <baird@adacore.com>

        * einfo.ads (Extra_Accessibility): Update associated comment to use
        the term "present" correctly ("present" just means that it is not
        an error to query the value of the attribute - it does not imply
        that the value must be non-null).
        (Extra_Constrained): Ditto.
        (Is_Visible_Formal): Ditto.
        (Extra_Accessibility_Of_Result) Ditto; also add Inline pragma.
        (Set_Extra_Accessibility_Of_Result): Add Inline pragma.

        * exp_ch6.adb (Expand_Call): The callee may require an
        Extra_Accessibility_Of_Result actual parameter even if Ada_Version
        < Ada_2012. This can occur if the callee is exported from a Gnat
        runtimes unit. Also improve a comment.

2011-09-06  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch7.adb: Add with and use clauses for Get_Targ.
        (Alignment_Of): Rename formal parameter Some_Typ
        to Typ, update related comment. Use the allocator alignment on
        strict alignment targets such as SPARC.
        (Double_Alignment_Of): Rename formal parameter Some_Typ to Typ, update
        related comment.

2011-09-06  Gary Dismukes  <dismukes@adacore.com>

2011-09-06  Robert Dewar  <dewar@adacore.com>

        * sem_util.adb, exp_ch6.adb: Minor reformatting and code reorganization.

2011-09-06  Steve Baird  <baird@adacore.com>

        * einfo.ads (Extra_Accessibility_Of_Result): New function; in the
        (Ada2012) cases described in AI05-0234 where the accessibility
        level of a function result is "determined by the point of
        call", an implicit parameter representing that accessibility
        level is passed in. Extra_Accessibilty_Of_Result yields this
        additional formal parameter. Extra_Accessibility_Of_Result
        is analogous to the existing Extra_Accessibility
        function used in the implementation of access parameters.
        (Set_Extra_Accessibility_Of_Result): New procedure; sets
        Extra_Accessibility_Of_Result attribute.
        * einfo.adb (Extra_Accessibility_Of_Result): New function.
        (Set_Extra_Accessibility_Of_Result): New procedure.
        (Write_Field19_Name): Display Extra_Accessibilty_Of_Result attribute.
        * sem_util.adb (Dynamic_Accessibility_Level): Set Etype of
        an accessibility level literal to Natural; introduce a nested
        function, Make_Level_Literal, to do this.
        * exp_ch6.ads (Needs_Result_Accessibility_Level): New function;
        determines whether a given function (or access-to-function
        type) needs to have an implicitly-declared accessibility-level
        parameter added to its profile.
        (Add_Extra_Actual_To_Call): Export an existing procedure which was
        previously declared in the body of Exp_Ch6.
        * exp_ch6.adb (Add_Extra_Actual_To_Call): Export declaration by moving
        it to exp_ch6.ads.
        (Has_Unconstrained_Access_Discriminants): New Function; a
        predicate on subtype entities which returns True if the given
        subtype is unconstrained and has one or more access discriminants.
        (Expand_Call): When expanding a call to a function which takes an
        Extra_Accessibility_Of_Result parameter, pass in the appropriate
        actual parameter value. In the case of a function call which is
        used to initialize an allocator, this may not be possible because
        the Etype of the allocator may not have been set yet. In this
        case, we defer passing in the parameter and handle it later in
        Expand_Allocator_Expression.
        (Expand_Simple_Function_Return): When returning from a function which
        returns an unconstrained subtype having at least one access
        discriminant, generate the accessibility check needed to ensure that
        the function result will not outlive any objects designated by its
        discriminants.
        (Needs_Result_Accessibility_Level): New function; see exp_ch6.ads
        description.
        * exp_ch4.adb (Expand_Allocator_Expression): When a function call
        is used to initialize an allocator, we may need to pass in "the
        accessibility level determined by the point of call" (AI05-0234)
        to the function. Expand_Call, where such actual parameters are
        usually generated, is too early in this case because the Etype of
        the allocator (which is used in determining the level to be passed
        in) may not have been set yet when Expand_Call executes. Instead,
        we generate code to pass in the appropriate actual parameter
        in Expand_Allocator_Expression.
        * sem_ch6.adb (Create_Extra_Formals): Create
        the new Extra_Accessibility_Of_Result formal if
        Needs_Result_Accessibility_Level returns True. This includes the
        introduction of a nested procedure, Check_Against_Result_Level.

2011-09-06  Arnaud Charlet  <charlet@adacore.com>

        * gcc-interface/Makefile.in (X86_TARGET_PAIRS): Remove duplicate
        declaration.

2011-09-05  Hristian Kirtchev  <kirtchev@adacore.com>

        * s-finmas.adb (Set_Finalize_Address): Explain the reason
        for the synchronization. Move the test for null from
        s-stposu.Allocate_Any_Controlled to this routine since the check
        needs to be protected too.
        (Set_Heterogeneous_Finalize_Address): Explain the reason for the
        synchronization code.
        * s-finmas.ads (Set_Heterogeneous_Finalize_Address): Add comment
        explaining the context in which this routine is used.
        * s-stposu.adb (Allocate_Any_Controlled): Move the test for null

        (Lock_Entries_With_Status): New name for Lock_Entries with two
        arguments (changed to meet rtsfind no overloading rule).

2011-09-05  Hristian Kirtchev  <kirtchev@adacore.com>

        * s-finmas.adb (Set_Finalize_Address (Address,
        Finalize_Address_Ptr)): Renamed to Set_Heterogeneous_Finalize_Address.

        Finalize_Address_Ptr): Add synchronization code.
        * s-finmas.ads (Set_Finalize_Address (Address,
        Finalize_Address_Ptr)): Renamed to Set_Heterogeneous_Finalize_Address.
        * s-stposu.adb (Allocate_Any_Controlled): Update the call to
        Set_Finalize_Address for the heterogeneous case.

        * sem_ch3.adb (Prepare_Private_Subtype_Completion): Set parent
        of internal entity to the subtype declaration, so that when
        entities are subsequently exchanged in a package body, the tree
        remains properly formatted for ASIS.

2011-09-05  Johannes Kanig  <kanig@adacore.com>

        * g-comlin.adb (Set_Usage): Additional optional argument to set help

        * s-tassta.adb (Task_Wrapper): Ensure that we don't try to write the
        stack guard page on PPC Linux. This patch ensures the 64K guard page at
        the bottom of the stack is not overwritten.

2011-09-05  Thomas Quinot  <quinot@adacore.com>

        * exp_intr.adb, s-tasini.adb: Minor reformatting.

2011-09-05  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch3.adb (Access_Definition): If an access type declaration
        appears in a child unit, the scope of whatever anonymous type
        may be generated is the child unit itself.

2011-09-05  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch6.adb (Analyze_Expression_Function): Do not set
        Comes_From_Source on rewritten body.

        * exp_aggr.adb (Replace_Type): If the target of the assignment is
        a selected component and the right-hand side is a self-referential
        access, the proper prefix of the rewritten attribute is a copy
        of the left-hand side, not of its prefix.

2011-09-05  Jose Ruiz  <ruiz@adacore.com>

        * exp_ch9.adb (Make_Initialize_Protection): The fact that
        restriction No_Dynamic_Attachment is in effect or not should
        not influence the default priority associated to a protected
        object. With this change, when the restriction is in effect (as
        is the case for the Ravenscar profile) the default priority of
        a protected object with an interrupt handler is in the range of
        interrupt priorities (Default_Interrupt_Priority) as required
        by D.3(10).

2011-09-05  Arnaud Charlet  <charlet@adacore.com>

        information.

2011-09-05  Ed Schonberg  <schonberg@adacore.com>

        * par-ch6.adb (P_Subprogram): In Ada2012 mode, if the subprogram
        appears within a package specification and the token after "IS"
        is not a parenthesis, assume that this is an unparenthesized
        expression function, even if the token appears in a line by
        itself.
        * par.adb: Clarify use of Labl field of scope stack in error
        recovery.

2011-09-05  Bob Duff  <duff@adacore.com>

        * sem_res.adb (Resolve_Intrinsic_Operator): Use unchecked
        conversions instead of normal type conversions in all cases where a
        type conversion would be illegal. In particular, use unchecked
        conversions when the operand types are private.

2011-09-05  Johannes Kanig  <kanig@adacore.com>

        * lib-xref-alfa.adb (Is_Alfa_Reference): Never declare effects on

        * sem_ch6.adb (Analyze_Expression_Function): If the expression
        function comes from source, indicate that so does its rewriting,

        subprogram body (e.g. when it is a protected operation).
        * sem_ch4.adb: minor reformatting

2011-09-05  Hristian Kirtchev  <kirtchev@adacore.com>

        * lib.adb (Check_Same_Extended_Unit): Comment rewriting. Use
        Get_Source_Unit rather than Get_Code_Unit as instantiation unfolding
        may lead to wrong ancestor package in the case of instantiated subunit
        bodies. If a subunit is instantiated, follow the chain of instantiations
        rather than the stub structure.

        point of premature use.

        * sem_ch6.adb: (Check_Post_State): Suppress warning
        "postcondition refers only to pre-state" when the expression has not
        yet been analyzed, because it causes false alarms. This can happen when
        the postcondition contains a quantified expression, because those are
        analyzed later. This is a temporary/partial fix.
        (Process_Post_Conditions): Minor: change wording of warning.

        * s-htable.adb (Set_If_Not_Present): Use renaming

        * exp_ch6.adb (Add_Finalization_Master_Actual_To_Build_In_Place_Call):

        formal of the enclosing function. Fmaster_Actual is
        then passed to the new formal Master_Exp on the call to

        dimension indicator N, if present. Even though it is a static
        constant, its source location may be modified when printing
        expanded code under -gnatDL, and node sharing will lead to chaos
        in Sprint on large files, by generating a sloc value that does
        not correspond to any source file.

        a case of allocator expansion where the allocator is not expanded but
        needs a custom allocate routine. Code reformatting.
        (Is_Finalizable_Transient): Remove local variables Has_Rens and

        * sem_ch10.adb (Analyze_With_Clause): If the library unit

        (CPU_ZERO, CPU_SET): They are now mapped to the CPU_ZERO_S and CPU_SET_S
        respectively, so we need to pass the size of the masks as
        parameters.
        * s-taprop-linux.adb (Create_Task, Set_Task_Affinity): Use dynamically
        created cpu_set_t masks
        with the number of processors available in the target platform,

        are using a restricted run-time library, use the flag

        a constrained call, to ensure that all such cases get handled
        by simply passing on the caller's parameters. Also, in that
        case call Needs_BIP_Alloc_Form to determine whether to pass on
        the BIP_Alloc_Form parameter of the enclosing function rather
        than testing Is_Constrained. Add similar tests for the return
        of a BIP call to later processing to ensure consistent handling.

        * errout.ads, errout.adb (Error_Msg_PT): New routine. Used to factorize
        code.
        * sem_ch6.adb (Check_Conformance): Add specific error for wrappers of
        protected procedures or entries whose mode is not conformant.
        (Check_Synchronized_Overriding): Code cleanup: replace code which emits
        an error by a call to a new routine which report the error.

        been reported and a subprogram covering an interface primitive is not
        found then skip generating the internal entity. Done to avoid crashing
        the frontend.
        (Check_Abstract_Overriding): Change text of error of wrong formal of
        protected subprogram or entry. Done for consistency to emit exactly the
        same error reported by Check_Synchronized_Overriding. In addition, the
        error is restricted to protected types (bug found working on AI05-0090)

2011-08-30  Yannick Moy  <moy@adacore.com>

        volatile.

2011-08-30  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch3.adb (Expand_Freeze_Array_Type): Correct the call to
        Build_Finalization_Master by supplying an insertion node and enclosing
        scope. In its old version, the call did not generate a finalization
        master.
        (Expand_Freeze_Record_Type): Add local variable Has_AACC. Add code to
        recognize anonymous access-to-controlled components. Rewrite the
        machinery which creates finalization masters to service anonymous
        access-to-controlled components of a record type. In its current state,
        only one heterogeneous master is necessary to handle multiple anonymous
        components.
        (Freeze_Type): Comment reformatting.
        * rtsfind.ads: Add RE_Set_Is_Heterogeneous to tables RE_Id and
        RE_Unit_Table.
        * s-stposu.adb (Allocate_Any_Controlled): Rewrite the machinery which
        associates TSS primitive Finalize_Address with either the master itself
        or with the internal hash table depending on the mode of operation of
        the master.

2011-08-30  Javier Miranda  <miranda@adacore.com>

        * exp_ch3.adb (Make_Eq_If): If the etype of the _parent component is an
        interface type then do not generate code to compare this component.
        Required since they have no components and their equality operator is
        abstract.

2011-08-30  Steve Baird  <baird@adacore.com>

        * sem_util.ads (Deepest_Type_Access_Level): New function; for the type
        of a saooaaat (i.e, a stand-alone object of an anonymous access type),
        returns the (static) accessibility level of the object. Otherwise, the
        same as Type_Access_Level.
        (Dynamic_Accessibility_Level): New function; given an expression which
        could occur as the rhs of an assignment to a saooaaat (i.e., an
        expression of an access-to-object type), return the new value for the
        saooaaat's associated Extra_Accessibility object.
        (Effective_Extra_Accessibility): New function; same as
        Einfo.Extra_Accessibility except that object renames are looked through.
        * sem_util.adb 
        (Deepest_Type_Access_Level): New function; see sem_util.ads description.
        (Dynamic_Accessibility_Level): New function; see sem_util.ads
        description.
        (Effective_Extra_Accessibility): New function; see sem_util.ads
        description.
        * einfo.ads (Is_Local_Anonymous_Access): Update comments.
        (Extra_Accessibility): Update comments.
        (Init_Object_Size_Align): New procedure; same as Init_Size_Align
        except RM_Size field (which is only for types) is unaffected.
        * einfo.adb
        (Extra_Accessibility): Expand domain to allow objects, not just formals.
        (Set_Extra_Accessibility): Expand domain to allow objects, not just
        formals.
        (Init_Size): Add assertion that we are not trashing the
        Extra_Accessibility attribute of an object.
        (Init_Size_Align): Add assertion that we are not trashing the
        Extra_Accessibility attribute of an object.
        (Init_Object_Size_Align): New procedure; see einfo.ads description.
        * sem_ch3.adb (Find_Type_Of_Object): Set Is_Local_Anonymous_Access
        differently for the type of a (non-library-level) saooaaat depending
        whether Ada_Version < Ada_2012. This is the only point where Ada_Version
        is queried in this set of changes - everything else (in particular,
        setting of the Extra_Accessibility attribute in exp_ch3.adb) is
        driven off of the setting of the Is_Local_Anonymous_Access attribute.
        The special treatment of library-level saooaaats is an optimization,
        not required for correctnesss. This is based on the observation that the
        Ada2012 rules (static and dynamic) for saooaaats turn out to be
        equivalent to the Ada2005 rules in the case of a library-level saooaaat.
        * exp_ch3.adb
        (Expand_N_Object_Declaration): If Is_Local_Anonymous_Access is
        false for the type of a saooaaat, declare and initialize its
        accessibility level object and set the Extra_Accessibility attribute
        of the saooaaat to refer to this object.
        * checks.adb (Apply_Accessibility_Check): Add Ada 2012 saooaaat support.
        * exp_ch4.adb (Expand_N_In): Replace some Extra_Accessibility calls with
        calls to Effective_Extra_Accessibility in order to support
        renames of saooaaats.
        (Expand_N_Type_Conversion): Add new local function,
        Has_Extra_Accessibility, and call it when determining whether an
        accessibility check is needed.
        It returns True iff Present (Effective_Extra_Accessibility (Id)) would
        evaluate to True (without raising an exception).
        * exp_ch5.adb
        (Expand_N_Assignment_Statement): When assigning to an Ada2012
        saooaaat, update its associated Extra_Accessibility object (if
        it has one). This includes an accessibility check.
        * exp_ch6.adb (Add_Call_By_Copy_Code): When parameter copy-back updates
        a saooaaat, update its Extra_Accessibility object too (if it
        has one).
        (Expand_Call): Replace a couple of calls to Type_Access_Level
        with calls to Dynamic_Access_Level to handle cases where
        passing a literal (any literal) is incorrect.
        * sem_attr.adb (Resolve_Attribute): Handle the static accessibility
        checks associated with "Saooaat := Some_Object'Access;"; this must
        be rejected if Some_Object is declared in a more nested scope
        than Saooaat.
        * sem_ch5.adb (Analyze_Assignment): Force accessibility checking for an
        assignment to a saooaaat even if Is_Local_Anonymous_Access
        returns False for its type (indicating a 2012-style saooaaat).
        * sem_ch8.adb
        (Analyze_Object_Renaming): Replace a call to Init_Size_Align
        (which is only appropriate for objects, not types) with a call
        of Init_Object_Size_Align in order to avoid trashing the
        Extra_Accessibility attribute of a rename (the two attributes
        share storage).
        * sem_res.adb
        (Valid_Conversion) Replace six calls to Type_Access_Level with
        calls to Deepest_Type_Access_Level. This is a bit tricky. For an
        Ada2012 non-library-level saooaaat, the former returns library level
        while the latter returns the (static) accessibility level of the
        saooaaat. A type conversion to the anonymous type of a saooaaat
        can only occur as part of an assignment to the saooaaat, so we
        know that such a conversion must be in a lhs context, so Deepest
        yields the result that we need. If such a conversion could occur,
        say, as the operand of an equality operator, then this might not
        be right. Also add a test so that static accessibilty checks are
        performed for converting to a saooaaat's type even if
        Is_Local_Anonymous_Access yields False for the type.

2011-08-30  Javier Miranda  <miranda@adacore.com>

        * sem_disp.adb (Check_Dispatching_Operation): Complete condition that
        controls generation of a warning associated with late declaration of
        dispatching functions. Required to avoid generating spurious
        warnings.

2011-08-30  Gary Dismukes  <dismukes@adacore.com>

        * sem_ch6.adb (Check_Return_Subtype_Indication): Issue error if the
        return object has an anonymous access type and the function's type is
        a named access type.
        * sem_ch8.adb (Analyze_Object_Renaming): Suppress error about renaming
        conversions on implicit conversions, since such conversions can occur
        for anonymous access cases due to expansion. Issue error for attempt
        to rename an anonymous expression as an object of a named access type.
        * sem_res.ads (Valid_Conversion): Add defaulted parameter Report_Errs,
        to indicate whether this function should report errors on invalid
        conversions.
        * sem_res.adb (Resolve): For Ada 2012, in the case where the type of
        the expression is of an anonymous access type and the expected type is
        a named general access type, rewrite the expression as a type
        conversion, unless this is an expression of a membership test.
        (Valid_Conversion.Error_Msg_N): New procedure that conditions the
        calling of Error_Msg_N on new formal Report_Errs.
        (Valid_Conversion.Error_Msg_NE): New procedure that conditions the
        calling of Error_Msg_NE on new formal Report_Errs.
        (Valid_Conversion): Move declaration of this function to the package
        spec, to allow calls from membership test processing. For Ada 2012,
        enforce legality restrictions on implicit conversions of anonymous
        access values to general access types, disallowing such conversions in
        cases where the expression has a dynamic accessibility level (access
        parameters, stand-alone anonymous access objects, or a component of a
        dereference of one of the first two cases).
        * sem_type.adb (Covers): For Ada 2012, allow an anonymous access type
        in the context of a named general access expected type.
        * exp_ch4.adb Add with and use of Exp_Ch2.
        (Expand_N_In): Add processing for membership tests applied to
        expressions of an anonymous access type. First, Valid_Conversion is
        called to check whether the test is statically False, and then the
        conversion is expanded to test that the expression's accessibility
        level is no deeper than that of the tested type. In the case of
        anonymous access-to-tagged types, a tagged membership test is applied
        as well.
        (Tagged_Membership): Extend to handle access type cases, applying the
        test to the designated types.
        * exp_ch6.adb (Expand_Call): When creating an extra actual for an
        accessibility level, and the actual is a 'Access applied to a current
        instance, pass the accessibility level of the type of the current
        instance rather than applying Object_Access_Level to the prefix. Add a
        ??? comment, since this level isn't quite right either (will eventually
        need to pass an implicit level parameter to init procs).

        * s-taskin.ads: Minor comment fix.

2011-08-30  Ed Schonberg  <schonberg@adacore.com>

        * sem_res.adb (Check_Parameterless_Call): If the node is a selected
        component and the selector is a dispatching operation, check if it is
        a prefixed call before rewriting as a parameterless function call.

        in ALFA mode.

        * exp_ch3.adb (Freeze_Type): Generate an accessibility check which
        ensures that the level of the subpool access type is not deeper than
        that of the pool object.
        * sem_util.adb (Object_Access_Level): Expand to handle defining
        identifiers.
        * sem_res.adb (Resolve_Allocator): Add a guard to avoid examining the
        subpool handle name of a rewritten allocator.

        * exp_dist.adb (TC_Rec_Add_Process_Element): For a choice with multiple
        values, we generate multiple triples of parameters in the TypeCode.
        Bump Choice_Index for each such triple so that a subsequent default
        choice is associated with the correct index in the typecode.

2011-08-29  Bob Duff  <duff@adacore.com>

        * sem_ch10.adb (Analyze_With_Clause,Install_Withed_Unit): Abandon
        processing if we run across a node with no Scope. This can happen if
        we're with-ing an library-level instance, and that instance got errors
        that caused "instantiation abandoned".
        * sem_util.adb (Unit_Declaration_Node): Make it more robust, by raising
        an exception instead of using Assert, so it won't go into an infinite
        loop, even when assertions are turned off.

        * sem_util.adb, sem_util.ads (Itype_Has_Declaration): New function to
        know if an Itype has a corresponding declaration, as defined in

        * s-tasuti.adb (Make_Passive): Work around race condition in
        Make_Independent, which can cause Wait_Count to be zero. So instead of
        asserting that Wait_Count > 0, and then decrementing it, decrement it
        only if Wait_Count > 0.
        * s-taskin.ads (Wait_Count, Alive_Count, Awake_Count): All of these
        should be nonnegative, so declare them Natural instead of Integer.

        node is not itself an entity but a selected component, it is a

        processing for .NET/JVM. These targets can now benefit from
        Raise_From_Controlled_Operation and they share the same processing with
        standard targets.

        These targets need transient scopes in order to properly finalize short
        lived controlled objects.

         NET/JVM. These targets can now benefit from
        Raise_From_Controlled_Operation and they share the same processing with

        (between unit names and truncated base names without suffixes).

        Requires_Cleanup_Actions.
        (Expand_N_Package_Body): Package bodies may need clean up code

        code depending on whether they contain tagged types.
        (Unregister_Tagged_Types): New routine. Search through a list of

        * exp_disp.adb (Make_DT): Generate code to check the external tag ONLY
        if the tagged type has a representation clause which specifies its

        (Resolve_Record_Aggregate): if the type has invisible components
        because of a private ancestor, the aggregate is illegal.

        * s-tasren.adb (Task_Do_Or_Queue): Previous code was reading
        Acceptor.Terminate_Alternative without locking Acceptor, which causes a
        race condition whose symptom is to fail to lock Parent. That, in turn,
        causes Parent.Awake_Count to be accessed without locking Parent, which
        causes another race condition whose symptom is that Parent.Awake_Count
        can be off by 1 (either too high or too low). The solution is to lock
        Parent unconditionally, and then lock Acceptor, before reading
        Acceptor.Terminate_Alternative.

        constraint that subtype must come from source code to be in ALFA, so
        that anonymous subtypes can be in ALFA too.

2011-08-04  Yannick Moy  <moy@adacore.com>

        * sem_ch3.adb (Analyze_Object_Declaration): remove obsolete addition of
        reference for ALFA mode.

        Add support for overriding the Project_Path in aggregate projects.

2011-08-04  Robert Dewar  <dewar@adacore.com>

        * a-cofove.ads: Minor reformatting.

2011-08-04  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch7.adb (Build_Adjust_Or_Finalize_Statements): Update the comment
        on the generated code.

        (Gen_Adafinal_Ada): Remove redundant test.  In the non-main program
        case, do not call System.Standard_Library.Adafinal; instead call
        finalize_library if needed.
        (Gen_Adafinal_C): Likewise.

        objects here.
        (Gen_Output_File_Ada): Generate pragma Linker_Destructor for Ada_Final
        if -a is specified.  Call Gen_Elab_Externals_Ada.  Move around call to
        Gen_Adafinal_Ada.
        (Gen_Output_File_C): Generate __attribute__((destructor)) for Ada_Final
        if -a is specified.  Call Gen_Elab_Externals_C.  Remove useless couple
        of external declarations.  Call Gen_Finalize_Library_C.

2011-08-04  Emmanuel Briot  <briot@adacore.com>

        * prj.adb, prj.ads, makeutl.adb, makeutl.ads (Complete_Mains,
        Compute_Compilation_Phases): new subprogram.
        (Builder_Data, Builder_Project_Tree_Data): new subprogram and type
        The number of mains as well as the various compilation phases that
        need to be run are now project tree specific, since various
        aggregated trees might have different requirements. In particular,
        they do not all require bind or link phases.

2011-08-04  Emmanuel Briot  <briot@adacore.com>

        * prj.adb, prj.ads, makeutl.adb, makeutl.ads, prj-env.adb
        (Project_Tree_Appdata): New type.
        It is now possible to associate application-specific data to a project
        tree. In particular, this is used in the gprbuild builder to avoid a
        number of global tables and htables, especially now that there can be
        several project trees loaded at once because of aggregate projects.
        (Debug_Name): new procedure.
        * projects.texi: Clarify syntax of "**" for Source_Dirs

2011-08-03  Emmanuel Briot  <briot@adacore.com>

        the "roots" for a main.
        (Fill_From_Project): add support for aggregate projects. Main units
        in aggregated projects are now automatically added in the list of
        files to build (although this fails later on in gprbuild, because
        these files are not using the root proejct tree, so this needs
        further cleanup)
        * gcc-interface/Make-lang.in: Update dependencies.

2011-08-03  Yannick Moy  <moy@adacore.com>

        * sem_ch4.adb (Analyze_Conditional_Expression): only allow boolean

2011-08-03  Emmanuel Briot  <briot@adacore.com>

        * make.adb, prj.adb, prj.ads, makeutl.adb, makeutl.ads
        (Insert_Project_Sources, Insert_withed_Sources_For): moved from the
        gprbuild sources.
        These packages are more logically placed in the Queue package, since
        they manipulate the queue. It is also likely that they can be adapted
        for gnatmake, thus sharing more code.
        (Finish_Program, Fail_Program): moved from the gprbuild sources, so
        that we could move the above.

2011-08-03  Emmanuel Briot  <briot@adacore.com>

        * errutil.adb (Finalize): clean up the list of error messages on exit.
        Calling this subprogram multiple times will no longer show duplicate
        error messages on stderr.

2011-08-03  Emmanuel Briot  <briot@adacore.com>

        * g-comlin.adb, g-comlin.ads (Set_Command_Line): ignore the parameter
        Getopt_Switches when we have already define a command line
        configuration.

2011-08-03  Yannick Moy  <moy@adacore.com>

        * sem_ch11.adb (Analyze_Raise_xxx_Error): do not mark such nodes as not
        in ALFA. Instead, they are considered as assertions to prove.
        * sem_ch4.adb (Analyze_Conditional_Expression): do not always mark such
        nodes as not in ALFA. Instead, include conditional expressions in ALFA
        if they have no ELSE part, or if they occur in pre- and postconditions,
        where the Condition cannot have side-effects in ALFA
        (Analyze_Membership_Op): do not mark such nodes as not in ALFA
        (Analyze_Type_Conversion): do not always mark such nodes as not in ALFA.
        Instead, include type conversion between scalar types in ALFA.
        * sem_ch6.adb (Process_Formals): correctly mark a parameter in ALFA
        if-and-only-if its type is in ALFA.

2011-08-03  Thomas Quinot  <quinot@adacore.com>

        * scos.adb, get_scos.adb, put_scos.adb

        * einfo.adb, einfo.ads (Is_Postcondition_Proc): new flag for procedure
        entities with get/set subprograms, which is set on procedure entities
        generated by the compiler for a postcondition.
        * sem_ch6.adb (Process_PPCs): set new flag on postcondition procedures
        * alfa.adb, alfa.ads (Get_Entity_For_Decl): new function returning the
        entity for a declaration
        (Get_Unique_Entity_For_Decl): new function returning an entity which
        represents a declaration, so that matching spec and body have the same
        entity.

2011-08-03  Robert Dewar  <dewar@adacore.com>

        front-end prevents its definition as a local subprogram
        (Traverse_Compilation_Unit): extract new procedure from Add_ALFA_File,
        for reuse in other contexts
        (Traverse_Declarations_Or_Statements,
        Traverse_Handled_Statement_Sequence, Traverse_Package_Body,
        Traverse_Package_Declaration, Traverse_Subprogram_Body): make all these
        procedures take a callback parameter to be called on all declarations
        * lib-xref.ads
        (Traverse_All_Compilation_Units): new generic function to traverse a
        compilation unit and call a callback parameter on all declarations

2011-08-03  Javier Miranda  <miranda@adacore.com>

        * sem_prag.adb (Process_Interface_Name): Allow duplicated export names
        in Java since they are always enclosed in a namespace that
        differentiates them, and overloaded entities are supported by the VM.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

        * checks.adb (Determine_Range): If a computed bound of an operation is
        outside the range of the base type of the expression, and overflow
        checks are enabled, the result is unknown and cannot be used for any
        subsequent constant folding.
        * sem_eval.adb (Compile_Time_Compare): if the bounds of one operand are
        unknown, so is the result of the comparison.

        include Abort_Id.
        * exp_ch7.ads (Build_Object_Declarations): Moved from body to spec.

        inside the freeze node.
        (Process_Declarations): Add code to detect whether a freeze node has a
        nested finalization collection.

2011-08-03  Pascal Obry  <obry@adacore.com>

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

        * sem_warn.adb (Check_One_Unit): if the only mention of a withed unit
        is a renaming declaration in the private part of a package, do not emit
        a warning that the with_clause could be moved because the renaming may
        be used in the body or in a child unit.

2011-08-03  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration):

        * exp_ch7.adb (Build_Raise_Statement): Do not call
        Raise_From_Controlled_Operation when this routine is not present in
        the run-time library.
        (Cleanup_Protected_Object, Cleanup_Task): For restricted run-time
        libraries (Ravenscar), tasks are non-terminating, and protected objects
        and tasks can only appear at library level, so we do not want
        finalization of protected objects nor tasks.
        * exp_intr.adb: Minor clarification in comment.
        bindgen.adb (Gen_Adainit_Ada, Gen_Main_C, Gen_Output_File_Ada,

        * exp_ch13.adb: Add with and use clause for Targparm;
        (Expand_N_Free_Statement): Prevent the generation of a custom
        Deallocate on .NET/JVM targets since this requires pools and address
        arithmetic.
        * exp_ch4.adb (Expand_Allocator_Expression): When compiling for
        .NET/JVM targets, attach the newly allocated object to the access
        type's finalization collection. Do not generate a call to
        Set_Finalize_Address_Ptr on .NET/JVM because this routine does not
        exist in the runtime.
        (Expand_N_Allocator): When compiling for .NET/JVM targets, do not
        create a custom Allocate for object that do not require initialization.
        Attach a newly allocated object to the access type's finalization
        collection on .NET/JVM.
        * exp_ch5.adb (Make_Tag_Ctrl_Assignment): Add special processing for
        assignment of controlled types on .NET/JVM. The two hidden pointers
        Prev and Next and stored and later restored after the assignment takes
        place.
        * exp_ch6.adb (Expand_Call): Add local constant Curr_S. Add specialized
        kludge for .NET/JVM to recognize a particular piece of code coming from
        Heap_Management and change the call to Finalize into Deep_Finalize.
        * exp_ch7.adb (Build_Finalization_Collection): Allow the creation of
        finalization collections on .NET/JVM only for types derived from
        Controlled. Separate the association of storage pools with a collection
        and only allow it on non-.NET/JVM targets.
        (Make_Attach_Call): New routine.
        (Make_Detach_Call): New routine.
        (Process_Object_Declarations): Suppress the generation of
        build-in-place return object clean up code on .NET/JVM since it uses
        pools.

        (Make_Detach_Call): New routine.
        * exp_intr.adb Add with and use clause for Targparm.

        * a-except.adb, a-except-2005.adb (Raise_From_Controlled_Operation):
        Rewritten to create the message strings when the exception is not
        raised by an abort during finalization.
        * a-except.ads, a-except-2005.ads: Add pragma Export for procedure
        Raise_From_Controlled_Operation and update its associated comment.
        * a-fihema.ads, a-fihema.adb: New GNAT unit.
        Ada.Finalization.Heap_Management provides key functionality
        associated with controlled objects on the heap, their creation,
        finalization and reclamation. Type Finalization_Collection is
        effectively a wrapper which sits ontop of a storage pool and performs
        all necessary bookkeeping for all the objects it contains. Each
        access-to-controlled or access-to-class-wide type receives a collection
        as part of its expansion. The compiler generates buffer code and
        invokes Allocate / Deallocate to create and destroy allocated
        controlled objects.
        * a-finali.adb ("="): Removed.
        * a-finali.ads ("="): Removed. Controlled types no longer carry hidden
        fields Prev and Next.
        * ali.adb (Scan_ALI): Add parsing code to process PF / Has_Finalizer.
        A library unit with at least one controlled object on the library level
        has a special finalizer which is invoked by the binder. To signal this,
        ali files carry field PF.
        * ali.ads: New field in type Unit_Record called Has_Finalizer. Add
        associated comment on field usage.
        * a-tags.adb (Get_RC_Offset): Removed.
        (Needs_Finalization): New routine.
        * a-tags.ads: Update the structure of the GNAT dispatch tables.
        Dispatch tables now carry field Needs_Finalization which provides
        runtime indication whether a type is controlled or has controlled
        components or both. Remove field RC_Offset.
        (Get_RC_Offset): Removed along with its associated pragma Export.
        Since tagged types with controlled components no longer carry hidden
        field _controller, the special mechanism to retrieve its location is no
        longer needed.
        (Needs_Finalization): New routine.
        * atree.ads, atree.adb (Elist24): New routine.
        (Set_Elist24): New routine.
        * atree.h: Add a define clause for Elist24.
        * bindgen.adb New library-level variable Lib_Final_Built.
        (Gen_Adafinal_Ada): Reimplemented. Depending on the restrictions or the
        presence of a VM target, the routine generates calls to the proper
        library finalization routine.
        (Gen_Adainit_Ada): Import Finalize_Library_Objects only on non-VM
        targets. Set the correct library finalization routine depending on
        whether the library has controlled objects or this is a VM compilation.
        (Gen_Finalize_Library_Ada): New routine. This procedure generates calls
        to library-level finalizers of compiled units in reverse order of
        elaboration. It also produces exception management code and reraises a
        potential exception after all units have been finalized.
        (Gen_Finalize_Library_C): New routine. This procedure generates calls to
        library-level finalizers of compiled units in reverse order of
        elaboration.
        (Gen_Finalize_Library_Defs_C): New routine. This procedure generates the
        definitions of all library-level finalizers available to the compilation
        (Gen_Main_Ada): Directly call Adafinal which now contails all target
        dependent code.
        (Gen_Main_C): Add new local constant Needs_Library_Finalization. Call
        System.Standard_Library.Adafinal directly. If the library needs
        finalization actions, create the sequence of finalization calls.
        (Gen_Output_File_Ada): Alphabetize local variables and constants.
        Generate a with clause for System.Soft_Links when compiling for a VM.
        Remove the code which imports System.Standard_Library.Adafinal as
        Do_Finalize. Generate the library finalization routine.
        (Gen_Output_File_C): Add new local constant Needs_Library_Finalization.
        If the library needs finalization actions, create all the definitions
        of library- level finalizers.

        unit has a library-level finalizer.
        Add type Qualification_Mode.

        low bound is not known at compile time but they have no others choice.

        case of the rewriting of a derived type that constrains the
        discriminants of its parent type.
        Avoids redundant subprogram derivations for private subtype derivations.

2011-08-03  Javier Miranda  <miranda@adacore.com>

        raising an exception.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

        * sem_res.adb (Set_String_Literal_Subtype): if index type is an integer
        type, always use 1 as the lower bound or string, even if lower bound of
        context is not static, to handle properly null strings in a non-static
        context.

2011-08-03  Bob Duff  <duff@adacore.com>

        * sem_prag.adb (Resolve_Aggregate): An array aggregate with 'others' is
        always legal on the right-hand side of an assignment statement; there
        is always an applicable index constraint in this case. Therefore, the
        check for Pkind = N_Assignment_Statement is now unconditional -- it
        doesn't depend on whether Is_Constrained (Typ).

2011-08-03  Robert Dewar  <dewar@adacore.com>

        * exp_ch5.adb, sem_prag.adb, exp_ch4.adb: Minor reformatting.

        * exp_ch5.adb (Expand_N_Assignment_Statement): Do not force inlining of
        tagged assignment when discriminant checks are suppressed. This is
        useless and extremely costly in terms of static stack usage.

2011-08-03  Bob Duff  <duff@adacore.com>

        * sem_prag.adb (Get_Base_Subprogram): Do not follow Alias for instances
        of generics, because this leads to the wrong entity in the wrong scope,
        causing (e.g.) pragma Export_Procedure to get an error if the entity is
        an instance.
        (Process_Interface_Name): Follow Alias for instances of generics, to
        correct for the above change.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

        * exp_ch4.adb (Expand_N_Selected_Component): If the discriminant value
        is an integer literal it is always safe to replace the reference. In
        addition, if the reference appears in the generated code for an object
        declaration it is necessary to copy because otherwise the reference
        might be to the uninitilized value of the discriminant of the object
        itself.

2011-08-03  Pascal Obry  <obry@adacore.com>

        * adaint.c (__gnat_is_executable_file_attr): Fix Win32 circuitry when no

        * sem_aggr.adb (Analyze_Array_Aggregate): When checking the discrete
        choices of a named array aggregate, bail out when any choices are
        marked as Errors_Posted.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

        * exp_ch13.adb (Expand_N_Freeze_Entity): cleanup determination of scope
        in which entity is frozen, to handle properly loop variables in
        iterators.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

        * sem_res.adb (Set_String_Literal_Subtype): if the lower bound of the
        subtype is not static, compute the upper bound using attributes, to
        handle properly index types that are not integer types.

2011-08-03  Bob Duff  <duff@adacore.com>

        * gnat_rm.texi, gnat_ugn.texi: Fix some dangling URLs.
        Update copyright notice.

        Ada2012 iterator, the loop will be rewritten during expansion into a
        while loop with a cursor and an element declaration. Do not analyze the
        body in this case, because if the container is for indefinite types the
        actual subtype of the elements will only be determined when the cursor
        declaration is analyzed.

2011-08-02  Arnaud Charlet  <charlet@adacore.com>

        * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Ignore

2011-08-02  Gary Dismukes  <dismukes@adacore.com>

        * sem_ch3.adb (Check_Ops_From_Incomplete_Type): Remove call to
        Prepend_Element, since this can result in the operation getting the
        wrong slot in the full type's dispatch table if the full type has
        inherited operations. The incomplete type's operation will get added
        to the proper position in the full type's primitives
        list later in Sem_Disp.Check_Operation_From_Incomplete_Type.
        (Process_Incomplete_Dependents): Add Is_Primitive test when checking for
        dispatching operations, since there are cases where nonprimitive
        subprograms can get added to the list of incomplete dependents (such
        as subprograms in nested packages).
        * sem_ch6.adb (Process_Formals): First, remove test for being in a
        private part when determining whether to add a primitive with a
        parameter of a tagged incomplete type to the Private_Dependents list.
        Such primitives can also occur in the visible part, and should not have
        been excluded from being private dependents.
        * sem_ch7.adb (Uninstall_Declarations): When checking the rule of
        RM05-3.10.1(9.3/2), test that a subprogram in the Private_Dependents
        list of a Taft-amendment incomplete type is a primitive before issuing
        an error that the full type must appear in the same unit. There are
        cases where nonprimitives can be in the list (such as subprograms in
        nested packages).
        * sem_disp.adb (Derives_From): Use correct condition for checking that
        a formal's type is derived from the type of the corresponding formal in
        the parent subprogram (the condition was completely wrong). Add
        checking that was missing for controlling result types being derived
        from the result type of the parent operation.

        before accessing operands.
        * sem_util.adb (Is_SPARK_Initialization_Expr): follow original nodes to
        decide whether an initialization expression respects SPARK rules, as
        the plain node is the expanded one. This allows for more valid warnings
        to be issued.

        association.
        * errout.adb (First_Node): Exclude nodes with no Sloc, and always use
        the Original_Node.

2011-08-02  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch5.adb (Expand_Iterator_Loop): Code cleanup and refactoring.
        When a container is provided via a function call, generate a renaming
        of the function result. This avoids the creation of a transient scope
        and the premature finalization of the container.
        * exp_ch7.adb (Is_Container_Cursor): Removed.
        (Wrap_Transient_Declaration): Remove the supression of the finalization
        of the list controller when the declaration denotes a container cursor,
        it is not needed.

2011-08-02  Yannick Moy  <moy@adacore.com>

        * sem_ch3.adb, sem_ch3.ads (Analyze_Component_Declaration,
        Array_Type_Declaration): postpone the test for the type being a subtype
        mark after the type has been resolved, so that component-selection and
        expanded-name are discriminated.
        (Make_Index, Process_Range_Expr_In_Decl): add a parameter In_Iter_Schm
        to distinguish the case of an iteration scheme, so that an error is
        issed on a non-static range in SPARK except in an iteration scheme.
        * sem_ch5.adb (Analyze_Iteration_Scheme): call Make_Index with
        In_Iter_Schm = True.

        Is_Later_Declarative_Item to decice which declarations are allowed as

        mode, add that renamings are considered as later items.
        (Enclosing_Package): new function to return the enclosing package
        (Enter_Name): correct the rule for homonyms in SPARK
        (Is_SPARK_Initialization_Expr): default to returning True on nodes not

        command line now.
        * par-ch3.adb (P_Delta_Constraint): remove check in SPARK mode that the
        expression is a simple expression. This check cannot be performed in
        the semantics, so just drop it.
        (P_Index_Or_Discriminant_Constraint): move check that the index or
        discriminant is a subtype mark to Analyze_Subtype_Declaration in the
        semantics. Other cases were previously checked in the semantics.
        * par-ch4.adb (P_Name): move checks that a selector name is not
        character literal or an operator symbol to Find_Selected_Component in
        the semantics
        * par-ch5.adb (Parse_Decls_Begin_End): move check that basic
        declarations are not placed after later declarations in a separate
        procedure in Sem_Util (possibly not the best choice?), to be used both
        during parsing, for Ada 83 mode, and during semantic analysis, for
        SPARK mode.

        * restrict.adb, restrict.ads (Check_Formal_Restriction): add a
        parameter Force to issue the error message even on internal node (used
        for generated end label). Call Check_Restriction to check when an error
        must be issued. In SPARK mode, issue an error message even if the
        restriction is not set.

        discriminant constraint must be a subtype mark. Change the check that
        a subtype of String must start at one so that it works on subtype marks.
        * sem_ch4.adb (Analyze_Call): move here the check that a named
        association cannot follow a positional one in a call

        selector name is not a character literal or an operator symbol. Move
        here the check that the prefix of an expanded name cannot be a
        subprogram or a loop statement.
        * sem_util.adb, sem_util.ads (Check_Later_Vs_Basic_Declarations): new
        procedure called from parsing and semantics to check that basic

        * sem_ch5.adb (Analyze_Loop_Statement):  If the iteration scheme is an
        Ada2012 iterator, the loop will be rewritten during expansion into a
        while loop with a cursor and an element declaration. Do not analyze the

        actual subtype of the elements will only be determined when the cursor
        declaration is analyzed.

2011-08-02  Arnaud Charlet  <charlet@adacore.com>

        * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Ignore
        size/alignment related attributes in CodePeer_Mode.

2011-08-02  Gary Dismukes  <dismukes@adacore.com>

        * sem_ch3.adb (Check_Ops_From_Incomplete_Type): Remove call to
        Prepend_Element, since this can result in the operation getting the
        wrong slot in the full type's dispatch table if the full type has
        inherited operations. The incomplete type's operation will get added
        to the proper position in the full type's primitives
        list later in Sem_Disp.Check_Operation_From_Incomplete_Type.
        (Process_Incomplete_Dependents): Add Is_Primitive test when checking for
        dispatching operations, since there are cases where nonprimitive
        subprograms can get added to the list of incomplete dependents (such
        as subprograms in nested packages).
        * sem_ch6.adb (Process_Formals): First, remove test for being in a
        private part when determining whether to add a primitive with a
        parameter of a tagged incomplete type to the Private_Dependents list.
        Such primitives can also occur in the visible part, and should not have
        been excluded from being private dependents.
        * sem_ch7.adb (Uninstall_Declarations): When checking the rule of
        RM05-3.10.1(9.3/2), test that a subprogram in the Private_Dependents
        list of a Taft-amendment incomplete type is a primitive before issuing
        an error that the full type must appear in the same unit. There are
        cases where nonprimitives can be in the list (such as subprograms in
        nested packages).
        * sem_disp.adb (Derives_From): Use correct condition for checking that
        a formal's type is derived from the type of the corresponding formal in
        the parent subprogram (the condition was completely wrong). Add
        checking that was missing for controlling result types being derived
        from the result type of the parent operation.

        before accessing operands.
        * sem_util.adb (Is_SPARK_Initialization_Expr): follow original nodes to
        decide whether an initialization expression respects SPARK rules, as
        the plain node is the expanded one. This allows for more valid warnings
        to be issued.
        * gnat_rm.texi: Minor update.

2011-08-02  Arnaud Charlet  <charlet@adacore.com>

        association.
        * errout.adb (First_Node): Exclude nodes with no Sloc, and always use
        the Original_Node.

2011-08-02  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch5.adb (Expand_Iterator_Loop): Code cleanup and refactoring.
        When a container is provided via a function call, generate a renaming
        of the function result. This avoids the creation of a transient scope
        and the premature finalization of the container.
        * exp_ch7.adb (Is_Container_Cursor): Removed.
        (Wrap_Transient_Declaration): Remove the supression of the finalization
        of the list controller when the declaration denotes a container cursor,
        it is not needed.

2011-08-02  Yannick Moy  <moy@adacore.com>

        recognize also static ranges
        * sem_ch3.adb, sem_ch3.ads (Analyze_Component_Declaration,
        Array_Type_Declaration): postpone the test for the type being a subtype
        mark after the type has been resolved, so that component-selection and
        expanded-name are discriminated.
        (Make_Index, Process_Range_Expr_In_Decl): add a parameter In_Iter_Schm
        to distinguish the case of an iteration scheme, so that an error is
        issed on a non-static range in SPARK except in an iteration scheme.
        * sem_ch5.adb (Analyze_Iteration_Scheme): call Make_Index with
        In_Iter_Schm = True.

        concatenation argument of string type if it is static.
        * sem_util.adb, sem_util.ads
        (Check_Later_Vs_Basic_Declarations): add a new function
        Is_Later_Declarative_Item to decice which declarations are allowed as

        mode, add that renamings are considered as later items.
        (Enclosing_Package): new function to return the enclosing package
        (Enter_Name): correct the rule for homonyms in SPARK
        (Is_SPARK_Initialization_Expr): default to returning True on nodes not

        command line now.
        * par-ch3.adb (P_Delta_Constraint): remove check in SPARK mode that the

        the semantics, so just drop it.
        (P_Index_Or_Discriminant_Constraint): move check that the index or
        discriminant is a subtype mark to Analyze_Subtype_Declaration in the
        semantics. Other cases were previously checked in the semantics.
        * par-ch4.adb (P_Name): move checks that a selector name is not
        character literal or an operator symbol to Find_Selected_Component in
        the semantics
        * par-ch5.adb (Parse_Decls_Begin_End): move check that basic
        declarations are not placed after later declarations in a separate
        procedure in Sem_Util (possibly not the best choice?), to be used both
        during parsing, for Ada 83 mode, and during semantic analysis, for
        SPARK mode.
        * par-endh.adb (Check_End): move check that end label is not missing

        * restrict.adb, restrict.ads (Check_Formal_Restriction): add a
        parameter Force to issue the error message even on internal node (used
        for generated end label). Call Check_Restriction to check when an error
        must be issued. In SPARK mode, issue an error message even if the
        restriction is not set.

        discriminant constraint must be a subtype mark. Change the check that
        a subtype of String must start at one so that it works on subtype marks.
        * sem_ch4.adb (Analyze_Call): move here the check that a named
        association cannot follow a positional one in a call

        instead of issuing an error message directly
        * sem_ch8.adb (Find_Selected_Component): move here the check that a
        selector name is not a character literal or an operator symbol. Move
        here the check that the prefix of an expanded name cannot be a
        subprogram or a loop statement.
        * sem_util.adb, sem_util.ads (Check_Later_Vs_Basic_Declarations): new
        procedure called from parsing and semantics to check that basic
