        is less costly to store in records.
        * makeutl.adb:
        (Check_Source_Info_In_ALI): use Full_Source_Name instead of a direct
        call to Find_File, since the former provides caching when appropriate,
        which limits the number of system calls in some cases.
        * osint.ads, prj.ads (Source_Data): do not store directly the timestamp,
        but the file attributes since we also need access to the size of the

        homonyms of any renamed entity. Correct call to Generate_Entity to
        pass the homonym.

        * impunit.adb: Add packages that were added to the GNAT library:

        only to in and in out parameters (checks on parameter returns are
        handled in Expand_Actuals). If a scalar actual for a call to a derived
        subprogram is marked as needing a range check, peform it here (and set

        * sem_res.adb (Resolve_Slice): In the case where the prefix of the
        slice is itself a slice, pick up the Etype of the prefix. This handles
        the case where the prefix was an Image attribute expanded to a slice,
        and ensures that we get the subtype with the slice constraint rather
        than the unconstrained subbtype of the 'Image.

        * gcc-interface/Make-lang.in: Update dependencies
 
2009-06-24  Emmanuel Briot  
 
        * gnatcmd.adb, make.adb, mlib-prj.adb, prj.adb, prj.ads, clean.adb,
        prj-nmsc.adb, prj-env.adb, prj-proc.adb (Units_Table): Removed, since
        no longer useful.
        (Source_Data.Lang_Kind): Removed, since it duplicates information
        already available through Language.Config.
        (Source_Data.Compile): Removed, since information is already available
        through the language.
        (Is_Compilable): New subprogram.
        (Source_Data.Dependency): Removed, since already available through
        the language.
        (Source_Data.Object_Exist, Object_Linked): Removed since available
        through the language already.
        (Unit_Data.File_Names): Is now also set in multi_language mode, to
        bring the two modes closer in the resulting data structures.
        (Source_Data.Unit): Now a direct pointer to the unit data, rather than
        just the name that would point into a hash table.
        (Get_Language_From_Name): New subprogram.
 
2009-06-24  Javier Miranda  
 
        * exp_ch4.adb (Expand_N_Type_Conversion): Handle entities that are
        visible through limited-with context clauses. In addition, avoid an
        extra tag check that is not required when the class-wide
        designated types of the operand and target types are
        the same entity.
        (Tagged_Membership): Handle entities from the limited view.
 
2009-06-24  Emmanuel Briot  
 
        * gnatcmd.adb, make.adb, mlib-prj.adb, prj.ads, clean.adb,
        prj-nmsc.adb, prj-env.adb (File_Name_Data): removed
        (Spec_Or_Body): now a subtype of Source_Kind, to avoid using two
        different vocabularies for similar concepts (Impl/Body_Part and
        Spec/Specification).
        (Unit_Data): now points directly to a Source_Id, rather than duplicating
        some of the information in File_Name_Data. This also saves a bit of
        memory. However, since we are now using a pointer we need to test
        for null explicitly in several places of the code
 
2009-06-24  Javier Miranda  
 
        * exp_ch4.adb (Expand_N_Type_Conversion): return immediately

        it is coming from a limited view.
 
        * sem_res.adb: Remove with and use clauses for Sem_Ch10.
        (Full_Designated_Type): Use Available_View to extract the non-limited /
        full view of a type.

        * ali.ads: Mino reformatting.
 
        * gnat1drv.adb (Adjust_Global_Switches): New procedure (take care of
        turning off inlining if ASIS mode active).
 
        * switch-c.adb: Remove fiddling with Inspector_Mode and ASIS_Mode
        This belongs in gnat1drv.adb after switches are scanned.

        Add check which prevents the installation of a limited view if the
        non-limited view is already visible through a with clause.
        (Is_Legal_Shadow_Entity_In_Body): New routine. Detect a residual, but
        legal shadow entity which may occur in subprogram formals of anonymous
        access type.
 
        * sem_ch10.ads (Is_Legal_Shadow_Entity_In_Body): New routine.
 
        * sem_ch3.adb (Access_Definition): Remove the propagation of flag
        From_With_Type from the designated type to the generated anonymous
        access type. Remove associated comment.
 
        * sem_res.adb Add with and use clauses for Sem_Ch10.
        (Full_Designated_Type): Detect a legal shadow entity and retrieve its
        non-limited view. Since the shadow entity may replace a regular
        incomplete type, return the available full view.
 
2009-06-23  Ed Schonberg  
 
        * sem_ch10.adb (Remove_Limited_With_Clause): Clean up code that handles
        incomplete type declarations. Previous code was potentially quadratic

        indicated to gnatcheck, gnatpp or gnatmetric, always specify the list
        of sources using -files=, so that the distinction can be made by the

        * sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): Revert previous
        change. The context clause of a generic instance declaration must be
        preserved until the end of the compilation, because it may have to be
        installed/removed repeatedly.
        The latest change to sem.adb ensures that the context of both spec and
        body of an instance is traversed before the instance itself, making
        this patch redundant.

        * prj-nmsc.adb (Locate_Directory): Remove unused parameters, and add
        support for returning the directory even if it doesn't exist. This is
        used for the object directory, since we are always setting it to a
        non-null value, and we should set it to an absolute name rather than a
        relative name for the sake of external tools that might depend on it.

        (GNAT.Sockets.Receive_Vector, GNAT.Sockets.Send_Vector): Use
        C_Recvmsg/C_Sendmsg rather than Readv/C_Writev.
 
2009-04-29  Ed Schonberg  
 
        * sem_disp.adb (Check_Dispatching_Operation): if the dispatching
        operation is a body without previous spec, update the list of
        primitive operations to ensure that cross-reference information is
        up-to-date.
 
        * sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): When creating a
        new compilation unit node for the instance declaration, keep the
        context items of the original unit on it, so that the context of the
        instance body only holds the context inherited from the generic body.
 
2009-04-29  Bob Duff  
 
        * sem_res.adb: Minor comment fix.
 
2009-04-29  Thomas Quinot  
 
        * sem_elim.adb: Minor reformatting
 
2009-04-29  Ed Schonberg  
 
        * exp_aggr.adb (Convert_To_Positional): if the current unit is a
        predefined unit, allow arbitrary number of components in static
        aggregate, to ensure that the same level of constant folding applies
        for Ada 95 and Ada 05 versions of the file.
 
2009-04-29  Ed Schonberg  
 
        * sem_elim.adb (Check_Eliminated): Handle new improved eliminate
        information: no need for full scope check.
        (Eliminate_Error): Do not emit error in a generic context.
 
2009-04-29  Ed Falis  
 
        * adaint.c (__gnat_rmdir): return error code if VTHREADS is defined.
        VxWorks 653 POS does not support rmdir.
 
2009-04-29  Matteo Bordin  
 
        * s-stausa.adb, s-stausa.ads: Get_Usage_Range: changing the way
        results are printed.
 
2009-04-29  Arnaud Charlet  
 
        * s-taskin.adb (Initialize): Remove pragma Warnings Off and remove
        unused assignment.
 
2009-04-29  Thomas Quinot  
 
        * make.adb: Minor reformatting.
        Minor code reorganization throughout.
 
2009-04-29  Matteo Bordin  
 
        * s-stausa.ads: Changed visibility of type Task_Result: moved to
        public part to give application visibility over it.
        This is for future improvement and to build a public API on top of it.
        Changed record components name of type Task_Result to reflect the new
        way of reporting.
 
        * s-stausa.adb: Actual_Size_Str changed to reflect the new way of
        reporting Stack usage.
 
        * gnat_ugn.texi: Update doc of stack usage report.
 
        * g-tastus.ads, s-stusta.ads, s-stusta.adb: New files.
 
        * Makefile.rtl: Add new run-time files.
 
2009-04-29  Pascal Obry  
 
        * initialize.c: Do not expand quoted arguments.
 
2009-04-29  Emmanuel Briot  
 
        * prj-ext.adb, prj.adb, prj.ads: Fix memory leaks.
 
        * clean.adb (Ultimate_Extension_Of): removed, since duplicate of
         Prj.Ultimate_Extending_Project_Of
 
2009-04-29  Ed Schonberg  
 
        * exp_ch7.adb (Build_Final_List): If the designated type is a Taft
        Amendment type, add the with_clause for Finalization.List_Controller
        only if the current context is a package body.
 
2009-04-29  Thomas Quinot  
 
        * sem_ch12.adb: Minor reformatting
 
        * sem_aggr.adb: Minor reformatting
 
        * sem_ch6.adb, sem_cat.ads: Minor reformatting
 
        * sem_ch10.adb, gnat1drv.adb, prj-nmsc.adb: Minor reformatting
 
2009-04-29  Quentin Ochem  
 
        * prj.ads (Source_Id): Now general pointer type.
 
2009-04-29  Thomas Quinot  
 
        * exp_ch7.adb, rtsfind.adb: Minor reformatting
 
        * sem_res.adb: Minor reformatting
 
2009-04-29  Thomas Quinot  
 
        * sem_res.adb (Static_Concatenation): An N_Op_Concat with static
        operands is static only if it is a predefined concatenation operator.
 
        * sem_util.adb: Minor reformatting
 
        * sem_ch12.adb (Save_References): When propagating semantic information
        from generic copy back to generic template, for the case of an
        identifier that has been rewritten to an explicit dereference whose
        prefix is either an object name or a parameterless funcion call
        denoting a global object or function, properly capture the denoted
        global entity: perform the corresponding rewriting in the template,
        and point the rewritten identifier to the correct global entity (not
        to the associated identifier in the generic copy).
 
2009-04-29  Robert Dewar  
 
        * rtsfind.adb, prj-env.adb: Minor reformatting
        Minor code reorganization
 
2009-04-29  Emmanuel Briot  
 
        * make.adb: Fix comment
 
        * prj.adb (Ultimate_Extending_Project_Of): Fix handling when no project
        is given as argument, as might happen in gnatmake.
 
2009-04-29  Ed Schonberg  
 
        * sem_ch3.adb (Check_Abstract_Overriding): Improve error message when
        an abstract operation of a progenitor is not properly overridden by an
        operation of a derived synchronized type.
 
2009-04-29  Robert Dewar  
 
        * mlib-prj.adb, mlib-tgt.adb, mlib-tgt.ads, prj-nmsc.adb,
        prj-proc.adb: Minor reformatting
        Minor code reorganization
 
2009-04-29  Bob Duff  
 
        * exp_ch7.adb (Build_Final_List): For an access type that designates a
        Taft Amendment type, if the access type needs finalization, make sure
        the implicit with clause for List_Controller occurs on the package spec.
 
        * rtsfind.adb (Text_IO_Kludge): Fine tune the creation of implicit
        with's created for the pseudo-children of Text_IO and friends. In
        particular, avoid cycles, such as Ada.Wide_Text_IO.Integer_IO and
        Ada.Text_IO.Integer_IO both with-ing each other.
 
        * sem.adb (Walk_Library_Items): Suppress assertion failure in certain
        oddball cases when pragma Extend_System is used.
 
        * sem_ch12.adb (Get_Associated_Node): Prevent direct 'with' cycles in
        the case where a package spec instantiates a generic whose body with's
        this package, so Walk_Library_Items won't complain about cyclic with's.
 
2009-04-29  Emmanuel Briot  
 
        * gnatcmd.adb, prj-proc.adb, make.adb, mlib-prj.adb, prj.adb, prj.ads,
        prj-pp.adb, prj-pp.ads, makeutl.adb, clean.adb, prj-nmsc.adb,
        mlib-tgt.adb, mlib-tgt.ads, prj-util.adb, prj-env.adb, prj-env.ads
        (Project_Id): now a real pointer to Project_Data, instead of an index
        into the Projects_Table. This simplifies the API significantly, avoiding
        extra lookups in this table and the need to pass the Project_Tree_Ref
        parameter in several cases
 
2009-04-29  Nicolas Setton  
 
        * gcc-interface/Makefile.in: Produce .dSYM files for shared libs on
        darwin.
 
2009-04-25  Eric Botcazou  
 
        * gcc-interface/decl.c (gnat_to_gnu_entity) : Put
        back kludge.
 
2009-04-24  Robert Dewar  
 
        * mlib-prj.adb, prj-env.adb, prj-nmsc.adb, prj-proc.adb, make.adb,
        clean.adb: Minor reformatting.
        Minor code reorganization and message improvement.
 
2009-04-24  Emmanuel Briot  
 
        * prj-proc.adb, prj.adb, prj.ads, prj-nmsc.adb, prj-nmsc.ads
        (Alternate_Languages): now implemented as a malloc-ed list rather
        than through a table.
 
2009-04-24  Thomas Quinot  
 
        * sem_res.adb (Static_Concatenation): Simplify predicate to make it
        accurately handle cases such as "lit" & "lit" and
        "lit" & static_string_constant
 
2009-04-24  Emmanuel Briot  
 
        * prj-proc.adb, make.adb, mlib-prj.adb, prj.adb, prj.ads, clean.adb,
        prj-nmsc.adb, prj-env.adb (Project_List_Table, Project_Element):
        removed. Lists of projects are now implemented via standard malloc
        rather than through the table.
 
2009-04-24  Thomas Quinot  
 
        * sem_ch12.adb: Minor reformatting
 
        * g-trasym.adb: Minor reformatting
 
        * exp_ch6.adb: Minor reformatting
 
2009-04-24  Robert Dewar  
 
        * layout.adb (Layout_Type): For packed array type, copy unset
        size/alignment fields from the referenced Packed_Array_Type.
 
2009-04-24  Bob Duff  
 
        * lib-load.adb (Make_Instance_Unit): Revert previous change, no
        longer needed after sem_ch12 changes.
 
        * sem.adb (Walk_Library_Items): Include with's in some debugging
        printouts.
 
2009-04-24  Emmanuel Briot  
 
        * prj.ads, prj-nmsc.adb (Unit_Project): removed, since in fact we were
        only ever using the Project field.
 
2009-04-24  Ed Schonberg  
 
        * sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): Do not set
        Body_Required on the generated compilation node. The new node is linked
        to its body, but both share the same file, so we do not set this flag
        on the new unit so as not to create a spurious dependency on a
        non-existent body in the ali file for the instance.
 
2009-04-24  Robert Dewar  
 
        * make.adb: Minor reformatting
 
2009-04-24  Emmanuel Briot  
 
        * prj.adb, prj.ads, prj-nmsc.adb (Check_File, Record_Ada_Source,
        Add_Source): merge some code between those. In particular change where
        file normalization is done to avoid a few extra calls to
        Canonicalize_File_Name. This also removes the need for passing
        Current_Dir in a number of subprograms.
 
2009-04-24  Bob Duff  
 
        * lib-load.adb (Make_Instance_Unit): In the case where In_Main is
        False, assign the correct unit to the Cunit field of the new table
        entry. We want the spec unit, not the body unit.
 
        * rtsfind.adb (Make_Unit_Name, Maybe_Add_With): Simplify calling
        interface for these.
        (Maybe_Add_With): Check whether we're trying to a with on the current
        unit, and avoid creating such directly self-referential with clauses.
        (Text_IO_Kludge): Add implicit with's for the generic pseudo-children of
        [[Wide_]Wide_]Text_IO. These are needed for Walk_Library_Items,
        and matches existing comments in the spec.
 
        * sem.adb (Walk_Library_Items): Add various special cases to make the
        assertions pass.
 
        * sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): Use Body_Cunit
        instead of Parent (N), for uniformity.
 
2009-04-24  Robert Dewar  
 
        * errout.ads: Minor reformatting
 
2009-04-24  Emmanuel Briot  
 
        * gnat_ugn.texi (Library Projects): add documentation on gnatmake's
        behavior when the project includes sources from multiple languages
 
2009-04-24  Vincent Celier  
 
        * prj.adb (Has_Foreign_Sources): Returns True in Ada_Only mode if there
        is a language other than Ada declared.
 
        * makeutl.adb (Linker_Options_Switches): Call For_All_Projects with
        Imported_First set to True.
 
2009-04-24  Ed Schonberg  
 
        * sem_res.adb: additional optimization to inhibit creation of
        redundant transient scopes.
 
2009-04-24  Bob Duff  
 
        * rtsfind.ads: Minor comment fix
 
2009-04-24  Emmanuel Briot  
 
        * prj-proc.adb, prj-nmsc.adb (Find_Ada_Sources,
        Get_Path_Name_And_Record_Ada_Sources): merged, since these were
        basically doing the same work (for explicit or implicit sources).
        (Find_Explicit_Sources): renamed to Find_Sources to better reflect its
        role. Rewritten to share some code (testing that all explicit sources
        have been found) between ada_only and multi_language modes.
 
2009-04-24  Jerome Lambourg  
 
        * sem_prag.adb (Check_Form_Of_Interface_Name): Allow space in Ext_Name
        for CLI imported types.
        (Analyze_Pragma): Allow CIL or Java imported functions returning
        access-to-subprogram types.
 
2009-04-24  Emmanuel Briot  
 
        * make.adb, prj.adb, prj.ads, makeutl.adb, makeutl.ads:
        (Project_Data.Dir_Path): field removed, since it can be computed
        directly from .Directory, and is needed only once when processing the
        project is buildgpr.adb or make.adb
 
2009-04-24  Robert Dewar  
 
        * prj-env.adb, prj-proc.adb, prj.adb, prj.ads,
        rtsfind.adb: Minor reformatting.
        Minor code reorganization
 
2009-04-24  Arnaud Charlet  
 
        * mlib-prj.adb: Use friendlier english identifier.
 
        * gnatcmd.adb, make.adb: Use better english identifiers.
 
2009-04-24  Robert Dewar  
 
        * clean.adb: Minor reformatting
 
2009-04-24  Robert Dewar  
 
        * einfo.adb (OK_To_Rename): New flag
 
        * einfo.ads (OK_To_Rename): New flag
 
        * exp_ch3.adb (Expand_N_Object_Declaration): Rewrite as renames if
        OK_To_Rename set.
 
        * exp_ch4.adb (Expand_Concatenate): Mark temp variable OK_To_Rename
 
        * sem_ch7.adb (Uninstall_Declarations): Allow for renames from
        OK_To_Rename.
 
2009-04-24  Emmanuel Briot  
 
        * prj-proc.adb, make.adb, mlib-prj.adb, prj.adb, prj.ads, makeutl.adb,
        clean.adb, prj-nmsc.adb, prj-env.adb, prj-env.ads (Project_Data.Seen):
        field removed. This is not a property of the
        project, just a boolean used to traverse the project tree, and storing
        it in the structure prevents doing multiple traversal in parallel.
        (Project_Data.Checked): also removed, since it was playing the same role
        as Seen when we had two nested loops, and this is no longer necessary
        (For_All_Imported_Projects): removed, since in fact there was already
        the equivalent in For_Every_Project_Imported. The latter was rewritten
        to use a local hash table instead of Project_Data.Seen
        Various loops were rewritten to use For_Every_Project_Imported, thus
        removing the need for Project_Data.Seen. This avoids a lot of code
        duplication
 
2009-04-24  Ed Schonberg  
 
        * sem_res.adb (Resolve_Actuals): Do not create blocks around code
        statements, even though the actual of the call is a concatenation,
        because the argument is static, and we want to preserve warning
        messages  about sequences of code statements that are not marked
        volatile.
 
        * sem_warn.adb: remove obsolete comment about warning being obsolete
 
        * s-tasren.adb (Task_Do_Or_Queue): If a timed entry call is being
        requeued and the delay has expired while within the accept statement
        that executes the requeue, do not perform the requeue and indicate that
        the timed call has been aborted.
 
2009-04-24  Emmanuel Briot  
 
        * mlib-prj.adb, prj.adb, prj.ads, prj-nmsc.adb, prj-env.adb
        (Has_Ada_Sources, Has_Foreign_Sources): new subprograms
        (Project_Data.Ada_Sources_Present, Foreign_Sources_Present): removed,
        since they can be computed from the above.
 
2009-04-24  Vincent Celier  
 
        * gnatcmd.adb: Call Prj.Env.Initialize with the Project_Tree
 
        * prj-env.adb: Move all global variables to the private part of the
        project tree data.
        Access these new components instead of the global variables no longer
        in existence.
        (Add_To_Path): New Project_Tree_Ref parameter, to access the new
        components that were previously global variables.
 
        * prj-env.ads (Initialize): New Project_Tree_Ref parameter
        (Set_Mapping_File_Initial_State_To_Empty): New Project_Tree_Ref
        parameter.
 
        * prj-nmsc.adb (Compute_Unit_Name): New Project_Tree_Ref parameter to
        be able to call Set_Mapping_File_Initial_State_To_Empty with it.
 
        * prj.adb (Initialize): Do not call Prj.Env.Initialize
        (Reset): Do not call Prj.Env.Initialize. Instead, initialize the new
        components in the private part of the project tree data.
 
        * prj.ads (Private_Project_Tree_Data): new components moved from
        Prj.Env: Current_Source_Path_File, Current_Object_Path_File,
        Ada_Path_Buffer, Ada_Path_Length, Ada_Prj_Include_File_Set,
        Ada_Prj_Objects_File_Set, Fill_Mapping_File.
 
2009-04-24  Vincent Celier  
 
        * opt.ads (Unchecked_Shared_Lib_Imports): New Boolean flag.
 
        * prj-nmsc.adb (Check_Library): No error for imports by shared library
        projects, when --unchecked-shared-lib-imports is used.
 
2009-04-24  Robert Dewar  
 
        * sem_ch7.adb: Minor reformatting
 
2009-04-24  Tristan Gingold  
 
        * s-osinte-darwin.adb, s-osinte-darwin.ads: lwp_self now returns the
        mach thread id.
 
2009-04-24  Emmanuel Briot  
 
        * prj-env.adb, prj-env.ads (Body_Path_Name_Of, Spec_Path_Name_Of,
        Path_Name_Of_Library_Unit_Body): rEmove unused subprograms.
        (For_All_Imported_Projects): new procedure
        (For_All_Source_Dirs, For_All_Object_Dirs): Rewritten based on the
        above rather than duplicating code.
 
2009-04-24  Emmanuel Briot  
 
        * prj-proc.adb, prj.adb, prj.ads, prj-nmsc.adb, prj-env.adb
        (Source_Id, Source_Data): use a real list to store sources rather than
        using an external table to store the elements. This makes code more
        efficient and more readable.
 
2009-04-24  Emmanuel Briot  
 
        * prj-proc.adb, prj.adb, prj.ads, prj-nmsc.adb, prj-env.adb
        (Source_Iterator): new type.
        This removes the need for having the sources on three different
        lists at the project tree, project and language level. They are now
        on a single list.
 
2009-04-24  Emmanuel Briot  
 
        * gnatcmd.adb, prj.adb, prj.ads: Remove unused entities
 
2009-04-24  Ed Schonberg  
 
        * sem_warn.adb: Add comment on obsolete warning
 
2009-04-24  Arnaud Charlet  
 
        * s-tassta.adb (Create_Task): Fix violation of locking rule.
 
2009-04-24  Emmanuel Briot  
 
        * prj.adb, prj.ads, prj-nmsc.adb, prj-env.adb (Language_Index): renamed
        to Language_Ptr to better reflect its new implementation.
        (Project_Data.First_Languages_Processing): renamed to Languages now
        that the field with that name is no longer used
        (Project_Data.Languages): removed, no longer used, and duplicates
        information already available through First_Language_Processing.
        (Prj.Language_Index): now an actual pointer, instead of an index into
        a table. This makes the list somewhat more obvious, but more importantly
        removes the need to pass a pointer to the project_tree_data in a few
        places, and makes accessing the attributes of a languages more
        efficient.
 
2009-04-24  Richard Kenner  
            Thomas Quinot  
 
        * fe.h (Set_Identifier_Casing): Add const to second parameter.
        * gcc-interface/misc.c (internal_error_function): Make copy of return
        from pp_formatted_text before assigning BUFFER to it.
        (gnat_init): Likewise for main_input_filename and gnat_argv.
        (gnat_printable_name): Remove cast from call to Set_Identifier_Casing.
 
2009-04-24  Eric Botcazou  
 
        * ttypes.ads (Target_Double_Float_Alignment): New variable.
        (Target_Double_Scalar_Alignment): Likewise.
        * get_targ.ads (Get_Strict_Alignment): Adjust external name.
        (Get_Double_Float_Alignment): New imported function.
        (Get_Double_Scalar_Alignment): Likewise.
        * layout.adb (Set_Elem_Alignment): Take into account specific caps for

        "while X /= null loop" where X is unchanged inside the loop. We were
        not warning in this case, because of the pointers -- we feared that the
        loop variable could be updated via a pointer, if there are any pointers
        around the place. But that is impossible in this case.
 
        * sem_util.adb (May_Be_Lvalue): This routine was overly pessimistic in
        the case of dereferences. In X.all, X cannot be an l-value. We now
        catch that case (and implicit dereferences, too).

        (Analyze_Package_Instantiation): If generic unit in child instance is
        the same as generic unit in parent instance, look for an outer homonym
        to locate the desired generic.
 
2009-04-15  Bob Duff  
 
        * sem_ch5.adb (Analyze_Loop_Statement): Don't check for infinite loop
        warnings unless the loop comes from source, because checking generated
        loops is a waste of time, and makes it harder to debug
        Check_Infinite_Loop_Warning.
 
        * sem_warn.adb (Check_Infinite_Loop_Warning): If the local variable
        tested in the while loop is a renaming, do not warn. Otherwise, we get
        false alarms, because it's usually renaming something that we can't
        deal with (an indexed component, a global variable, ...).

        interface as a progenitor must be explicitly declared synchronized.
        Also check that a record extension cannot derive from a synchronized

        that generates the code needed to update a dispatch table when a
        primitive operation is declared with a subprogram body without previous
        spec. Insertion of the generated code is responsibility of the caller.
        (Make_DT): When building static tables, append the code created by
        Register_Primitive to update a secondary table after it has been
        constructed.
 
        * exp_ch3.adb, exp_ch6.adb: use new version of Register_Primitive.
