        prj-conf.adb, sem_ch13.adb, s-ficobl.ads: Minor reformatting

2011-08-05  Bob Duff  <duff@adacore.com>

        * a-stunau.ads, g-spipat.adb: Update comments.

2011-08-05  Bob Duff  <duff@adacore.com>

        is also a little more efficient in the not-so-unusual case where there
        are no controlled objects allocated.
        Make Finalization_Started flag atomic.
        (Finalize): Avoid unnecessary detachment of items from the list.
        (pcol): Minor cleanup.

        * gnatlink.adb (Gnatlink): No longer pass -gnat83/95/05/12 switch to
        gcc in CodePeer mode, since the binder generated file no longer has a
        'with Main'.

        * switch-c.adb: Update comment.

2011-08-05  Thomas Quinot  <quinot@adacore.com>

        * exp_ch4.adb (Expand_N_Type_Conversion): When expanding a predicate
        check, indicate that the copy of the original node does not come from
        source, to prevent an infinite recursion of the expansion.

2011-08-05  Johannes Kanig  <kanig@adacore.com>

        * debug.adb: document switch -gnatd.G for gnat2why, which deactivates
        VC generation for subprogram bodies.

2011-08-05  Yannick Moy  <moy@adacore.com>

        * einfo.ads: Typo.
        * sem_ch3.adb (Signed_Integer_Type_Declaration): in ALFA mode, define
        the base type with the smallest allowed base type.

2011-08-05  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch12.adb (Analyze_Formal_Package_Declaration): in an
        instantiation and a formal package the compiler generates a package
        renaming declaration so that the generic name within the declaration
        is interpreted as a renaming of the instance. At the end of a formal
        package declaration, this renaming must become invisible.

2011-08-05  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch7.adb (Is_Init_Call): Reimplemented to avoid character
        comparison and rely on concrete entities instead.

        that supports implicit dereference.
        * snames.ads-tmpl: Add names of aspects and attributes related to
        Ada2012 iterators: constant_indexing, default_iterator,
        iterator_element, implicit_dereference, variable_indexing.

        of calling the user-defined main subprogram. 
        (Gen_Main):  Declare Ada_Main_Program and (if CodePeer_Mode
        is set) Call_Main_Subprogram ahead of, as opposed to
        inside of, Main.

        generation of a "with" of the user-defined main subprogram.

        (Is_Finalization_Procedure): New routine. Returns True if the input
        entity denotes a [Deep_]Finalize routine.
        * sem_elab.ads (Check_Elab_Call): New formal parameter In_Init_Proc
        along with comment on usage.

2011-08-05  Yannick Moy  <moy@adacore.com>

        * exp_ch7.adb (Establish_Transient_Scope): in formal verification mode,
        if the node to wrap is a pragma check, this node and enclosed
        expression are not expanded, so do not apply any transformations here.
        * exp_prag.adb (Expand_Pragma_Check): document the need to avoid
        introducing transient scopes.

2011-08-05  Jose Ruiz  <ruiz@adacore.com>

        No_Default_Stream_Attributes is active, verify that all subcomponent
        types of the target have user-defined stream operations, and report
        error otherwise.
        * exp_ch3.adb (Stream_Operqtion_OK): use Type_Without_Stream_Operation.

        Needs_Elementary_Stream_Operation, to determine whether user-defined
        Read and Write attributes are available for the elementary components

        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

        * 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

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).

        (Expand_N_Package_Declaration): Package declarations may need clean up
        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.

2011-08-04  Bob Duff  <duff@adacore.com>

        * 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.

        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.
        (Build_Finalize_Statements): Update the comment on the generated code.
        (Build_Initialize_Statements): Update the comment on the generated code.
        (Build_Object_Declarations): Add local variable Result. The object
        declarations are now built in sequence.

        (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>

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>

        * 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.

        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_Object_Declarations. Update the call to Build_Raise_Statement to
        include Abort_Id.
        * exp_ch7.ads (Build_Object_Declarations): Moved from body to spec.

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>

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

        * sem_disp.adb (Is_Tag_Indeterminate): If the return type of the

        therfore is not Tag_Indeterminate, even if the function is marked as
        dispatching on result.

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

        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):

        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.

        * 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_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_Detach_Call): New routine.
        (Process_Object_Declarations): Suppress the generation of

        * 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.

        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.

        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.

        * sem_res.adb (Resolve_Op_Concat_Arg): if the argument is an aggregate
        and the component type is composite, this is ambiguous for predefined
        concatenation, but if the node is not overloaded and the entity is a use
        -defined function its profile can be used to resolve that aggregate.

        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.

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

        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.

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

        * sem_ch3.adb (Build_Discriminant_Constraints): Only use

        * 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

        * sem_ch3.adb (Derived_Type_Declaration): When checking that a untagged
        private type with a tagged full view is not derived in the immediate
        scope of the partial view, (RM 7.3 (7)) use the scope of the base type.

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>

        (Resolve_Array_Aggregate): refine the check for a static expression, to
        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.

        (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

        Check_Later_Vs_Basic_Declarations
        (Analyze_Subtype_Declaration): move here the check that an index or
        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

        * 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
