        Add with and use clause for Ada.Finalization. Type
        Iterator and Child_Iterator are now derived from Limited_Controlled.

        constant Loc. Preanalyze the loop iterator to discover whether
        it is a container iterator and if it is, wrap the loop in a

        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.

        remains properly formatted for ASIS.

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

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>

        * 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>

        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>

        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

        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.

        an incomplete type, set the Premature_Use for additional message.
        * sem_ch3.adb (Find_Type_Name): If partial view is incomplete
        and Premature_Use is set, place additional information at the
        point of premature use.

2011-09-02  Bob Duff  <duff@adacore.com>

        * 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.

2011-09-02  Marc Sango  <sango@adacore.com>

2011-09-02  Ed Schonberg  <schonberg@adacore.com>

        * sem_prag.adb (Analyze_PPC_In_Decl_Part): for a class-wide
        condition, a reference to a controlling formal must be interpreted

2011-09-02  Gary Dismukes  <dismukes@adacore.com>

        * exp_attr.adb (Expand_N_Attribute_Reference): Pass the
        underlying subtype rather than its base type on the call to
        Build_Record_Or_Elementary_Input_Function, so that any

2011-09-02  Bob Duff  <duff@adacore.com>

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

        Lor and Hir should not be done when OK1 is False.

2011-09-02  Gary Dismukes  <dismukes@adacore.com>

        * exp_ch6.adb (Add_Finalization_Master_Actual_To_Build_In_Place_Call):

        object of an enclosing BIP function set it to a
        new reference to the implicit finalization master
        formal of the enclosing function. Fmaster_Actual is
        then passed to the new formal Master_Exp on the call to
        Add_Finalization_Master_Actual_To_Build_ In_Place_Call. Move
        initializations of Enclosing_Func to its declaration.

2011-09-02  Thomas Quinot  <quinot@adacore.com>

        * sem_attr.adb: (Analyze_Attribute, case 'Range): when expanding
        X'range (N) into X'First (N) ..  X'Last (N), do not share the
        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.

2011-09-02  Bob Duff  <duff@adacore.com>

        * einfo.adb: (Has_Xref_Entry): Do not call
        Implementation_Base_Type. Lib.Xref has been

        no longer does. This is the one place where it is needed.

2011-09-02  Johannes Kanig  <kanig@adacore.com>

        * g-comlin.adb (Getopt): New optional argument Concatenate to have

        * exp_ch4.adb: (Expand_Allocator_Expression): Do not generate
        a call to Set_Finalize_Address if there is no allocator available.
        * exp_util.adb: (Build_Allocate_Deallocate_Proc): Account for
        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
        Ren_Obj. Code reformatting.
        (Is_Renamed): Renamed to Is_Aliased. Add code to detect aliasing
        through the use of 'reference.
        * sem_ch4.adb: (Analyze_Allocator): Detect allocators generated
        as part of build-in-place expansion. They are intentionally marked as
        coming from source, but their parents are not.

2011-09-02  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch10.adb (Analyze_With_Clause): If the library unit
        is the generated subprogram declaration for a child unit body
        that acts as spec, use the original body in the with_clause,
        to prevent binding errors.

2011-09-02  Vincent Celier  <celier@adacore.com>

2011-09-02  Ed Schonberg  <schonberg@adacore.com>

        * sem_util.adb (Note_Possible_Modification): If the entity
        being modified is the renaming generated for an Ada2012 iterator
        element, the enclosing container or array is modified as well.

2011-09-02  Jose Ruiz  <ruiz@adacore.com>

        * s-taprop-linux.adb (Initialize_Lock, Initialize_TCB,

        * sem_ch3.adb: (Build_Derived_Record_Type) Remove the kludgy update of
        access discriminant and anonymous access component scopes.
        (Inherit_Component): Reuse the itype of an access discriminant
        or anonymous access component by copying it in order to set the proper
        scope. This is done only when the parent and the derived type
        are in different scopes.

        (__gnat_cpu_zero, __gnat_cpu_set): Use the CPU_ZERO_S and

        CPU sets which are more portable across different glibc versions.
        * s-osinte-linux.ads (cpu_set_t_ptr, CPU_ALLOC, CPU_ALLOC_SIZE,
        CPU_FREE): Add this type and subprograms to be able to create cpu_set_t
        masks dynamically according to the number of processors in the target
        platform.
        (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,
        instead of static bit arrays. It enhances portability because
        it uses the information from the target platform.
        * sem_ch8.adb: (Attribute_Renaming): When checking whether we
        are using a restricted run-time library, use the flag
        Configurable_Run_Time_Mode instead of Restricted_Profile.

2011-09-01  Jose Ruiz  <ruiz@adacore.com>

        * s-taprop-linux.adb (Create_Task, Set_Task_Affinity): Use the linux
        macros for handling CPU sets (CPU_ZERO, CPU_SET) instead of modifying
        directly the bit array.
        * s-osinte-linux.ads (CPU_ZERO, CPU_SET): Import these wrappers around
        the linux macros with the same name.
        * adaint.h, adaint.c (__gnat_cpu_zero, __gnat_cpu_set): Create these
        wrappers around the CPU_ZERO and CPU_SET linux macros.

        * exp_ch6.ads (Needs_BIP_Alloc_Form): New utility function.
        * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration):
        Test for case where call
        initializes an object of a return statement before testing for
        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.
        (Needs_BIP_Alloc_Form): New utility function.
        * sem_ch6.adb: (Create_Extra_Formals): Replace test for adding

        for Is_Limited_Type and Is_Tagged_Type in condition checking
        for by-reference type.
        * inline.adb (Add_Inlined_Body): Only exclude init_procs. Other
        subprograms may have a completion because of a previous
        Inline_Always clause, but the enclosing package must be marked
        inlined for the subprogram body to become visible to the backend.

        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).

2011-08-30  Bob Duff  <duff@adacore.com>

        * 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

        (Generate_Dereference): New procedure to store a read/write dereferencew
        in the table Drefs.

        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.

        * 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.

        In_Same_Declaration_List, to implement AI05-0020: a user-defined
        equality on an anonymous access type whose designated type is private
        does not lead to an ambiguity with the universal access equality
        operator in the body or child units of the defining package. The same
        is true for a multiplication operator on a private type completed with
        a fixed-point-type.

        * exp_ch7.adb (Build_Raise_Statement): Remove the specialized
        processing for .NET/JVM. These targets can now benefit from
        Raise_From_Controlled_Operation and they share the same processing with
        standard targets.
        (Establish_Transient_Scope): Remove the restriction for .NET/JVM.
        These targets need transient scopes in order to properly finalize short
        lived controlled objects.
        (Make_Handler_For_Ctrl_Operation): Remove the specialized processing for
         NET/JVM. These targets can now benefit from

        a slightly more distinctive prefix string is used.

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

        * makeutl.adb (Complete_Mains): no longer accept unit names on the
        gnatmake command line.
        This behavior was never documented (and was supported only because of
        an early bug in the code). This case might lead to ambiguous cases
        (between unit names and truncated base names without suffixes).

        code depending on whether they contain tagged types.
        (Unregister_Tagged_Types): New routine. Search through a list of
        declarations or statements, looking for non-abstract Ada tagged types.
        For each such type, generate code to unregister the external tag.

        * bindgen.adb (Gen_Adainit_Ada): Move the generation of the declaration
        of the No_Param_Proc acc-to-subp type used for initialization of
        __gnat_finalize_library_objects so that it's declared at library level
        rather than nested inside of the adainit routine.

2011-08-04  Javier Miranda  <miranda@adacore.com>

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

        * 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 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.

2011-08-04  Eric Botcazou  <ebotcazou@adacore.com>

        * einfo.ads (Elaboration_Entity): Document new definition and use.
        (Elaboration_Entity_Required): Adjust to above change.
        * exp_attr.adb (Expand_N_Attribute_Reference): Likewise.
        * exp_ch12.adb: And with and use for Snames.
        (Expand_N_Generic_Instantiation): Test 'Elaborated attribute.
        * exp_util.adb (Set_Elaboration_Flag): Likewise.
        * sem_attr.adb (Analyze_Attribute) <Check_Library_Unit>: Delete.
        <Check_Unit_Name>: Deal with N_Expanded_Name.
        <Attribute_Elaborated>: Extend to all unit names.
        * sem_elab.adb: And with and use for Uintp.
        (Check_Internal_Call_Continue): Adjust to Elaboration_Entity change.
        * sem_util.ads (Build_Elaboration_Entity): Adjust comment.
        * sem_util.adb (Build_Elaboration_Entity): Change type to Integer.
        * bindgen.adb (Gen_Elab_Externals_Ada): New local subprogram taken
        from Gen_Adainit_Ada.
        (Gen_Elab_Externals_C): Likewise, but taken from Gen_Adainit_C.
        (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.
        (Gen_Adainit_Ada): Do not set SSL.Finalize_Library_Objects in the
        non-main program case.
        (Gen_Adainit_C): Generate a couple of external declarations here.
        In the main program case, set SSL.Finalize_Library_Objects.

        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>

        * prj.ads, makeutl.adb, makeutl.ads (Queue.Insert): now also inserts
        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
        conditional expression in ALFA.
        * sem_res.adb (Resolve_Conditional_Expression): mark non-boolean
        expressions as not in ALFA.

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

        * a-cofove.adb: Minor reformatting.

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
        New code letter for decisions: G (entry guard)
        * par_sco.adb
        (Traverse_Subprogram_Body): Rename to...
        (Traverse_Subprogram_Or_Task_Body): New subrpogram.
        (Traverse_Protected_Body): New subprogram
        (Traverse_Declarations_Or_Statements): Add traversal of task bodies,
        protected bodies and entry bodies.

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

        * 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>

        * a-except-2005.adb, a-cfhama.adb, a-cfhase.adb, a-cfhase.ads,
        a-cforma.adb, a-cforse.ads, a-cforse.adb: Minor reformatting

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

        * lib-xref-alfa.adb (Detect_And_Add_ALFA_Scope): make the subprogram
        library-level because retriction No_Implicit_Dynamic_Code in the
        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.

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

        * a-except-2005.adb (Raise_From_Controlled_Operation): Add new formal
        From_Abort. When finalization was triggered by an abort, propagate
        Standard'Abort_Signal rather than Program_Error.

        From_Abort.
        * a-except.adb (Raise_From_Controlled_Operation): Add new formal
        From_Abort. When finalization was triggered by an abort, propagate
        Standard'Abort_Signal rather than Program_Error.

        From_Abort.
        * exp_ch7.adb:(Build_Adjust_Or_Finalize_Statements): New local variable
        Abort_Id. Update the calls to Build_Object_Declarations and
        Build_Raise_Statement to include Abort_Id.

        calls to Build_Object_Declarations and Build_Raise_Statement to include
        Abort_Id.
        (Build_Finalize_Statements): New local variable Abort_Id. Update the
        calls to Build_Object_Declarations and Build_Raise_Statement to include
        Abort_Id.

        allowed on the target.
        (Build_Finalizer): New local variable Abort_Id.

        calls to Build_Object_Declarations and Build_Raise_Statement to include
        Abort_Id.
        (Build_Object_Declarations): Add new formal Abort_Id. Create the
        declaration of flag Abort_Id to preserve the original abort status
        before finalization code is executed.
        (Build_Raise_Statement): Add new formal Abort_Id. Pass Abort_Id to
        runtime routine Raise_From_Controlled_Operation.

        (Make_Handler_For_Ctrl_Operation): Add an actual for From_Abort.
        (Process_Transient_Objects): New local variable Abort_Id. Remove the
        clunky code to create all flags and objects related to
        exception propagation and replace it with a call to
        Build_Object_Declarations. Update the call to Build_Raise_Statement to
        include Abort_Id.
        * exp_ch7.ads (Build_Object_Declarations): Moved from body to spec.
        Add new formal Abort_Id and associated comment on its use.
        (Build_Raise_Statement): Add new formal Abort_Id and associated comment
        on its use.

        Remove the clunky code to create all flags and objects related to
        exception propagation and replace it with a call to
        Build_Object_Declarations. Update the call to Build_Raise_Statement.

2011-08-03  Eric Botcazou  <ebotcazou@adacore.com>

        * s-tassta.adb: Fix minor typos.

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

        * rtsfind.ads, makeutl.ads, prj.ads, prj.adb, make.adb,
        lib-writ.adb, makeutl.adb, s-soflin.ads, clean.adb: Minor reformatting.

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

        * exp_ch7.adb (Create_Finalizer): Treat freeze nodes in similar fashion
        to packages. This ensures that the finalizer body will not end up
        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>

        * g-awk.adb, g-awk.ads: Make GNAT.AWK API compatible with Ada 2005.
        (Current_Session): Return a not null access to Session_Type.
        (Default_Session): Likewise.

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

        * a-cfdlli.adb, bindgen.adb, exp_ch4.adb, exp_ch13.adb, sem_warn.adb,
        exp_ch3.adb, exp_ch3.ads: Minor reformatting.

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

        * g-awk.ads: Minor comment fix.

2011-08-03  Sergey Rybin  <rybin@adacore.com>

        * tree_io.ads (ASIS_Version_Number): Update because of the changes in
        the tree structure related to discriminant constraints.
        Original_Discriminant cannot be used any more for computing the
        defining name for the reference to a discriminant.

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

        * sem_disp.adb (Is_Tag_Indeterminate): If the return type of the
        function is not visibly tagged, this is not a dispatching call and
        therfore is not Tag_Indeterminate, even if the function is marked as
        dispatching on result.

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

        * exp_ch13.adb: Add with and use clauses for Restrict and Rident.
        (Expand_N_Free_Statement): Add a guard to protect against run-times
        which do not support controlled types.
        * exp_ch3.adb (Expand_Freeze_Class_Wide_Type): Add a guard to protect
        against run-times which do not support controlled types.
        * exp_ch4.adb (Complete_Controlled_Allocation): Add a guard to protect
        against run-times which do not support controlled types.
        * exp_ch7.adb (Build_Finalization_Collection): Add a guard to protect
        against run-times which do not support controlled types.
        * exp_util.adb (Needs_Finalization): Code reformatting. Add a guard to
        protect against run-times which do not support controlled types.

2011-08-03  Eric Botcazou  <ebotcazou@adacore.com>

        * exp_intr.adb: Put back with and use clauses for Exp_Ch11.
        (Expand_Unc_Deallocation): Expand the AT_END handler at the very end.

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

        * exp_ch5.adb (Expand_Iterator_Loop): indicate that the cursor is
        modified in the source, to prevent spurious warnings when compiling
        with -gnatg.

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

        * a-except-2005.adb: Minor reformatting.

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):
        Propagate the Comes_From_Source attribute from the original return
        object to the renaming.

2011-08-03  Jose Ruiz  <ruiz@adacore.com>

        * 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,
        Gen_Output_File_C): Remove references to finalization of library-level
        objects when using restricted run-time libraries.

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

        * sem_ch3.adb (Build_Discriminant_Constraints): Set
        Original_Discriminant only if the parent type is a generic formal.

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

        * 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.
        * exp_ch7.ads (Make_Attach_Call): New routine.
        (Make_Detach_Call): New routine.
        * exp_intr.adb Add with and use clause for Targparm.
        (Expand_Unc_Deallocation): Detach a controlled object from a collection
        on .NET/JVM targets.
        * rtsfind.ads: Add entries RE_Attach, RE_Detach and
        RE_Root_Controlled_Ptr to tables RE_Id and RE_Unit_Table.
        * snames.ads-tmpl: Add name Name_Prev. Move Name_Prev to the special
        names used in finalization.

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

        * a-fihema.adb: Add with and use clauses for System.Soft_Links.
        (Attach, Detach): Lock the current task when chaining an object onto a
        collection.

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

        * 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.

        not systematically lower case attribute indexes that contain no "."

        a unit name as index and therefore should be case insensitive.

        explicit dereference of an unconstrained type, create a constrained
        subtype for it, as is done for function calls that return an
        unconstrained type.

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

        * exp_aggr.adb (Flatten): Convert to positional form aggregates whose
        low bound is not known at compile time but they have no others choice.
        Done because in this case the bounds can be obtained directly from the
        aggregate.

        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>

        * exp_aggr.adb (Init_Hidden_Discriminants): New subprogram of

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

        * prj-pp.adb (Print): also output project qualifiers, since in

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

        * s-inmaop-vxworks.adb (Setup_Interrupt_Mask): Do nothing instead of
        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_aggr.adb: Minor reformatting.

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

        * 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
        ACL used, in this case we want to check for ending .exe, not .exe
        anywhere in the path.

2011-08-03  Sergey Rybin  <rybin@adacore.com>

        * tree_io.ads (ASIS_Version_Number): Update because of the changes in
        the tree structure (semantic decoration of references to record
        discriminants).

2011-08-03  Gary Dismukes  <dismukes@adacore.com>

        * 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.

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

        * sem_ch3.adb (Build_Discriminant_Constraints): Only use
        Original_Discriminant if within an instance.

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

        * sem_util.ads, exp_aggr.adb, exp_ch3.adb: Minor reformatting.

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

        * sem_ch3.adb (Analyze_Object_Declaration): if a constant object of an
        unconstrained type with discriminants is initialized with an aggregate,
        use the constrained subtype of the aggregate as the type of the object,
        because it is immutable, and this allows the back-end to generate no
        code for the object declaration.

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

        * exp_ch4.adb (Optimize_Length_Check): Fix bad handling of case where

2011-08-02  Vincent Celier  <celier@adacore.com>

        * adaint.c (file_names_case_sensitive_cache): New static int.
        (__gnat_get_file_names_case_sensitive): Cache the return value in
        file_names_case_sensitive_cache at the first invocation, to avoid

        sem_ch6.adb, sem_ch11.adb: Add semantic flag In_Pre_Post_Expression to
        indicate that we are in a precondition or postcondition. This is used in
        Mark_Non_ALFA_Subprogram (renaming of Mark_Non_ALFA_Subprogram_Body) to
        decide whether to flag the spec or body of the current subprogram as
        not in ALFA.

2011-08-02  Fabien Chouteau  <chouteau@adacore.com>

        * sem_ch3.adb (Analyze_Subtype_Declaration): Generate range
        compatibility checks for all indexes of an array subtype, not just the
        first. Reset Has_Dynamic_Range_Check on the subtype before each
        potential check to ensure that Insert_Range_Checks will not elide any
        of the dynamic checks.

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

        (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

        (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.

        (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

        (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.

        declarations are not placed after later declarations in a separate

        * restrict.adb, restrict.ads (Check_Formal_Restriction): add a
        parameter Force to issue the error message even on internal node (used

        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

        here the check that the prefix of an expanded name cannot be a

        * sem_util.adb, sem_util.ads (Check_Later_Vs_Basic_Declarations): new
        procedure called from parsing and semantics to check that basic

        unit that violates the -gnatyO switch.

2011-08-02  Ed Schonberg  <schonberg@adacore.com>

        * 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
        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
        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
        later items, in the two different modes Ada 83 and SPARK. In the SPARK
        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
        from source (result of expansion) to avoid issuing wrong warnings.

        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.
        * par-endh.adb (Check_End): move check that end label is not missing

        * par.adb: use and with Sem_Util, for use in Parse_Decls_Begin_End
        * 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.
        (Check_Restriction): new procedure with an additional out parameter to
        inform the caller that a message has been issued

        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
        * sem_ch5.adb (Check_Unreachable_Code): call Check_Formal_Restriction
        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
