        * makeutl.adb (Do_Complete): Call Debug_Output with the name of the
        project, not the source file name.
        * prj.adb (Find_Sources.Look_For_Sources): If the source has been

        if there is no other source with the same base name that is not locally
        removed.

2011-08-04  Ed Schonberg  <schonberg@adacore.com>

        * sem_res.adb (Resolve_Intrinsic_Operator): if the result type is
        private and one of the operands is a real literal, use a qualified
        expression rather than a conversion which is not meaningful to the
        back-end.

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

        * sem_ch13.adb (Aspect_Loop): when an aspect X and its classwise
        corresponding aspect X'Class are allowed, proceed with analysis of the
        aspect instead of skipping it.

2011-08-04  Tristan Gingold  <gingold@adacore.com>

        * s-flocon.adb, s-flocon.ads: Add a body for s-flocon.ads
        This will allow to have an Ada implementation for the subprogram.

2011-08-04  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch3.adb (Analyze_Full_Type_Declaration): If the declaration is a
        completion and aspects are present, apply them to the entity for the
        type which is currently the partial view, but which is the one that
        will be frozen.
        * sem_ch13.adb (Analyze_Aspect_Specifications): if the predicate
        applies to a partial view, indicate that the full view has predicates
        and delayed aspects.
        (Replace_Type_Reference): Handle properly predicates that apply to the
        full view of a private completion.

        issue warning and activate Implicit_Packing.
        (Freeze_Entity): Likewise.  Do not issue a warning for alias/atomic
        if the Esize is not known.

        is not known.
        <E_Record_Type>: Look at the RM size instead of the Esize.  Remove
        obsolete block.  
        Look at the RM size instead of the Esize for types if the latter is
        not known.
        (gnat_to_gnu_field): Use Known_Esize instead of Known_Static_Esize.

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...

        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

        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.

        (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.

        exception propagation and replace it with a call to
        Build_Object_Declarations. Update the call to Build_Raise_Statement.

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  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.

        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

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.
        Since tagged types with controlled components no longer carry hidden
        field _controller, the special mechanism to retrieve its location is no
        longer needed.
        (Needs_Finalization): New routine.
        * atree.ads, atree.adb (Elist24): New routine.
        (Set_Elist24): New routine.
        * atree.h: Add a define clause for Elist24.
        * bindgen.adb New library-level variable Lib_Final_Built.
        (Gen_Adafinal_Ada): Reimplemented. Depending on the restrictions or the
        presence of a VM target, the routine generates calls to the proper
        library finalization routine.
        (Gen_Adainit_Ada): Import Finalize_Library_Objects only on non-VM
        targets. Set the correct library finalization routine depending on
        whether the library has controlled objects or this is a VM compilation.
        (Gen_Finalize_Library_Ada): New routine. This procedure generates calls
        to library-level finalizers of compiled units in reverse order of
        elaboration. It also produces exception management code and reraises a
        potential exception after all units have been finalized.
        (Gen_Finalize_Library_C): New routine. This procedure generates calls to
        library-level finalizers of compiled units in reverse order of
        elaboration.
        (Gen_Finalize_Library_Defs_C): New routine. This procedure generates the
        definitions of all library-level finalizers available to the compilation
        (Gen_Main_Ada): Directly call Adafinal which now contails all target
        dependent code.
        (Gen_Main_C): Add new local constant Needs_Library_Finalization. Call
        System.Standard_Library.Adafinal directly. If the library needs
        finalization actions, create the sequence of finalization calls.
        (Gen_Output_File_Ada): Alphabetize local variables and constants.
        Generate a with clause for System.Soft_Links when compiling for a VM.
        Remove the code which imports System.Standard_Library.Adafinal as
        Do_Finalize. Generate the library finalization routine.
        (Gen_Output_File_C): Add new local constant Needs_Library_Finalization.
        If the library needs finalization actions, create all the definitions
        of library- level finalizers.
        (Has_Finalizer): New routine. Determines whether at least one compiled
        unit has a library-level finalizer.
        Add type Qualification_Mode.
        (Set_Unit_Name): Add a formal which controls the replacement of a dot.
        * einfo.adb: New usage of field 15 as Return_Flag.
        Remove Finalization_Chain_Entity from the usages of field 19.
        Remove Associated_Final_Chain from the usages of field 23.
        New usage of field 23 as Associated_Collection.
        New usage of field 24 as Finalizer.
        New usage of flag 252 as Is_Processed_Transient.
        (Associated_Final_Chain): Removed.
        (Associated_Collection): New routine.
        (Finalization_Chain_Entity): Removed.
        (Finalizer): New routine.
        (Is_Finalizer): New routine.
        (Is_Processed_Transient): New routine.
        (Return_Flag): New routine.

        * 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

        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

        * 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.

        * 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_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.

        compatibility checks for all indexes of an array subtype, not just the
        first. Reset Has_Dynamic_Range_Check on the subtype before each

        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

        private part when determining whether to add a primitive with a

        * sem_ch7.adb (Uninstall_Declarations): When checking the rule of

        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.

        * 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

        (Wrap_Transient_Declaration): Remove the supression of the finalization
        of the list controller when the declaration denotes a container cursor,

        (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.

        (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.

        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.

        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

        * gnat_rm.texi: Clarify doc on pragma Source_File_Name[_Project].

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

        * 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  Robert Dewar  <dewar@adacore.com>

        * exp_ch4.adb: Minor reformatting.

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.

        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>

        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

        * 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_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
