2004-10-04  Robert Dewar  <dewar@gnat.com>

        * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
        IF and CASE.
        (Analyze_Block_Statement): Add circuitry to detect following dead code
        (Check_Unreachable_Code): Handle case of block exit

2004-10-04  Robert Dewar  <dewar@gnat.com>

        * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
        (XMatchD): Avoid warning for Logic_Error call

2004-10-04  Robert Dewar  <dewar@gnat.com>

        * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
        consider expressions buried within a procedure actual to be an actual.
        This caused some blowups with uses of packed slices within a procedure
        actual.

2004-10-04  Robert Dewar  <dewar@gnat.com>

        * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
        longer need to be initialized to zero.
        (Get_Simple_Init_Val): Modular packed arrays no longer need to be
        initialized to zero.

        * checks.adb (Expr_Known_Valid): Packed arrays are now always
        considered valid, even if the representation is modular. That's correct
        now that we no longer initialize packed modular arrays to zero.

        * exp_dbug.ads: Clarify documentation on handling of PAD and JM
        suffixes. These are now documented as the only cases in which the
        debugger ignores outer records.
        Previously, the spec allowed arbitrary suffixes for this purpose.
        Change name of LJM to JM for packed array pad records
        Create separate section on packed array handling, and add a whole new
        set of comments to this section describing the situation with packed
        modular types and justification requirements depending on endianness.

2004-10-04  Robert Dewar  <dewar@gnat.com>

        * a-except.adb: Add a comment for last change

        * einfo.ads: Minor spelling correction in comment

        * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting

        * sem_ch11.adb: Fix a case of using | instead of \ for continuation
        messages.

        * sem_util.ads: Minor comment update

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

        * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
        Inline_Always when in Configurable_Run_Time mode.

        * sem_prag.adb (Process_Convention): If entity is an inherited
        subprogram, apply convention to parent subprogram if in same scope.
        (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
        when in Configurable_Run_Time mode.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

        * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
        class_wide type after component list has been inherited.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

        * sem_ch12.adb (Check_Generic_Actuals): New predicate
        Denotes_Previous_Actual, to handle properly the case of a private
        actual that is also the component type of a subsequent array actual.
        The visibility status of the first actual is not affected when the
        second is installed.
        (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
        make fully recursive the treatment of formals of packages declared
        with a box.
        (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
        the above on exit from an instantiation.
        (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
        current instantiation which is now complete.
        (Analyze_Package_Instantiation): No instantiated body is needed if the
        main unit is generic. Efficient, and avoid anomalies when a instance
        appears in a package accessed through rtsfind.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

        * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
        do not generate a declaration for a temporary if the call is part of a
        library-level instantiation.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

        * sem_util.adb (Explain_Limited_Type): Ignore internal components when
        searching for a limited component to flag.

        * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
        expansion of Input, to account for the fact that the implicit call
        generated by the attribute reference must freeze the user-defined
        stream subprogram. This is only relevant to 'Input, because it can
        appear in an object declaration, prior to the body of the subprogram.

        * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
        expansion can proceed and further errors uncovered.
        (Minor clean up): Fix cases of using | instead of \ for continuation
        messages.

2004-10-04  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

        * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.

        * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
        (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
        Use gcc_assert and gcc_unreachable.

        * decl.c (gnat_to_gnu_entity, case object): Check and process a
        specified alignment before validating size.
        (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
        stripped-down declaration for the type of the inner field when making
        a JM type.

        * utils.c (finish_record_type): Do not compute the size in units
        incrementally. Instead compute it once for the rep clause case.
        Use gcc_assert and gcc_unreachable.

2004-10-04  Vincent Celier  <celier@gnat.com>

        * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
        in file name.
        (Is_Valid_Path_Name): Take '/' as a directory separator.

2004-10-04  Vincent Celier  <celier@gnat.com>

        * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
        (Extended_Project) only if Extended_Project is defined, to avoid
        assertion error.
        (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
        resolved path.
        (Parse_Single_Project): Ditto.

        * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
        Add_To_Project_Path for virtual projects.

        mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb, 
        mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb, 
        mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
        parameter Options_2.

        * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
        Build_Dynamic_Library with an empty Options_2.

        * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
        default anymore.

        * makegpr.adb (Get_Imported_Directories.add): Remove trailing
        directory separator, if any.

        (Library_Opts): New table to store Library_Options.
        (Build_Library): If Library_Options is specified, pass these options
        when building a shared library.

2004-10-04  Jose Ruiz  <ruiz@act-europe.fr>

        * s-tposen.adb (Service_Entry): The object must be always unlocked at
        the end of this procedure now that the unlock operation was inserted
        by the expander.

2004-10-04  Jose Ruiz  <ruiz@act-europe.fr>

        * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
        corresponding to the Preallocated_Stacks flags in System.
        (Get_Target_Parameters): Including the processing for
        Preallocated_Stacks.

        * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads, 
        system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

        system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads, 
        system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
        used to signal whether the compiler creates the required stacks and
        descriptors for the different tasks (when True) or it is done by the
        underlying operating system at run time (when False).
        It is initially set to False in all targets.

        * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
        if it is supported by the target.
        (Make_Task_Create_Call): Pass the stack address if it has been
        previously created. Otherwise pass a Null_Address.

        * snames.adb: Add _stack.

        * snames.ads: Add Name_uStack. Required to allow the expander to
        statically allocated task stacks.

        * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
        Stack_Address argument.
        Check that its value is equal to Null_Address because this target does
        not support the static stack allocation.

2004-10-04  Thomas Quinot  <quinot@act-europe.fr>

        * usage.adb: Change "pragma inline" to "pragma Inline" in information
        and error messages

2004-10-04  Thomas Quinot  <quinot@act-europe.fr>

        * exp_dist.adb: Split declaration of asynchronous flag out of
        Add_RACW_Read_Attribute.
        Minor reformatting for better alignment with PolyORB version.
        Store the entity for the asynchronous flag of an RACW, rather than the
        expression, in the asynchronous flags table. This will allow this flag
        to be used in other subprograms beside Add_RACW_Read_Attribute.

2004-10-04  Thomas Quinot  <quinot@act-europe.fr>

        * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

        g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads:  Add new
        sockets constant MSG_NOSIGNAL (Linux-specific).
        Add new sockets constant MSG_Forced_Flags, list of flags to be set on
        all Send operations.
        For Linux, set MSG_NOSIGNAL on all send operations to prevent them
        from trigerring SIGPIPE.
        Rename components to avoid clash with Ada 2005 possible reserved
        word 'interface'.
        (Check_Selector): When the select system call returns with an error
        condition, propagate Socket_Error to the caller.

2004-10-01  Jan Hubicka  <jh@suse.cz>

        * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

2004-09-23  Robert Dewar  <dewar@gnat.com>

        PR ada/17540

        * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
        instead do this at freeze time (we won't do it if there is an address
        clause).
        Change "pragma inline" to "pragma Inline" in information and error
        messages.
        Minor reformatting.

        * freeze.adb (Check_Address_Clause): Remove previous change, not the
        right way of doing things after all.
        (Freeze_Entity): For object, set Is_Public for imported entities
        unless there is an address clause present.

2004-09-21  Olivier Hainque  <hainque@act-europe.fr>

        * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
        dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
        ensures proper handling of types with rep clauses, which might have
        their TYPE_SIZE set already.

2004-09-21  Robert Dewar  <dewar@gnat.com>

        * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
        packed array types in both little- and big-endian cases. This change
        ensures that we no longer count on the unused bits being initialized
        for such types (and in particular ensures that equality testing will
        only read the relevant bits).
        Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
        These changes mean that we no longer need to initialize small packed
        arrays.
        (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
        optimization to an LJM field as to its parent field.

        * ada-tree.h, trans.c, utils.c, utils2.c:
        Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P

2004-09-20  Jan Hubicka  <jh@suse.cz>

        * utils.c (gnat_finalize): Remove.
        (end_subprog_body): Directly call cgraph_finalize_function;
        do not lower the nested functions.

2004-09-20  Robert Dewar  <dewar@gnat.com>

        PR ada/17540

        * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
        if an address clause is present, since that means that the Import
        should be ignored.

2004-09-20  Arnaud Charlet  <charlet@act-europe.fr>

        * 5tsystem.ads: Removed, no longer used.

2004-09-17  Jeffrey D. Oldham  <oldham@codesourcery.com>
            Zack Weinberg  <zack@codesourcery.com>

        * ada-tree.def: Use tree_code_class enumeration constants
        instead of code letters.
        * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
        Update for new tree-class enumeration constants.

2004-09-17  Vincent Celier  <celier@gnat.com>

        an existing directory.
        (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
        (Size (String)): Function C_Size returns Long_Integer, not File_Size.
        Convert the result to File_Size.

        * prj.ads: (Project_Error): New exception

        * prj-attr.adb: Except in procedure Initialize, Fail comes from
        Prj.Com, not from Osint.
        (Attrs, Package_Attributes): Tables moved to private part of spec
        (Add_Attribute, Add_Unknown_Package): Moved to new child package
        Prj.Attr.PM.
        (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
        Prj.Project_Error after call to Fail.
        (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
        Fail. Check that package name is not already in use.

        * prj-attr.ads: Comment updates to indicate that all subprograms may be
        used by tools, not only by the project manager, and to indicate that

        (Add_Unknown_Package, Add_Attribute): Moved to new child package
        Prj.Attr.PM.
        (Attrs, Package_Attributes): Table instantiations moved from the body to
        the private part to be accessible from Prj.Attr.PM body.

        from new package Prj.Attr.PM.
        (Parse_Attribute_Declaration): Call Add_Attribute from new package
        Prj.Attr.PM.

        * Makefile.in: Add prj-attr-pm.o to gnatmake object list

        * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
        instead of Elaboration_Checks).

        * a-calend.adb: Minor reformatting

        insertion of the statement raising Program_Error. The run time
        contains the required machinery for handling that.

        * sem_util.ads: Change comment associated to procedure
        Check_Potentially_Blocking_Operation.
        This procedure does not insert a call for raising the exception because
        that is currently done by the run time.

        * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.

        * init.c: Add the global variable __gl_detect_blocking that indicates
        whether pragma Detect_Blocking is active (1) or not (0). Needed for
        making the pragma available at run time.
        (__gnat_set_globals): Pass and update the detect_blocking parameter.

        * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
        pragma Detect_Blocking is active.

        * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.

        * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
        DB is found in the ali file. Any unit compiled with pragma
        Detect_Blocking active forces its effect in the whole partition.

        * a-retide.adb (Delay_Until): Raise Program_Error if pragma
        Detect_Blocking is active and delay is called from a protected
        operation.

        * bindgen.adb (Gen_Adainit_Ada): When generating the call to
        __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
        Detect_Blocking is active (0 otherwise).
        (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
        as Detect_Blocking parameter if pragma Detect_Blocking is active (0
        otherwise).

2004-09-09  Thomas Quinot  <quinot@act-europe.fr>

        * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
        GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
        package.

        * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
        (Register_Receiving_Stub): Add Subp_Info formal parameter.
        Update API in placeholder implemetation of s-parint to reflect changes
        in distribution runtime library.

        * sem_ch3.adb (Expand_Derived_Record): Rename to
        Expand_Record_Extension.

        * sem_disp.adb (Check_Controlling_Formals): Improve error message for
        primitive operations of potentially distributed object types that have
        non-controlling anonymous access formals.

        * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
        subprogram.
        New implementation of expansion for remote access-to-subprogram types,
        based on the RACW infrastructure.
        This version of sem_dist is compatible with PolyORB/DSA as well as
        GLADE.

        * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
        Asynchrronous that applies to a remote access-to-subprogram type, mark
        the underlying RACW type as asynchronous.

        * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
         __gnat_using_gnu_linker to 1.

        * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
        g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
        GNAT.Perfect_Hash_Generators, and remove the empty
        GNAT.Perfect_Hash package.

        * atree.adb: Minor reformatting

        * exp_ch3.adb (Expand_Derived_Record): Rename to
        Expand_Record_Extension.
        (Build_Record_Init_Proc.Build_Assignment): The default expression in
        a component declaration must remain attached at that point in the
        tree so New_Copy_Tree copies it if the enclosing record type is derived.
        It is therefore necessary to take a copy of the expression when building
        the corresponding assignment statement in the init proc.
        As a side effect, in the case of a derived record type, we now see the
        original expression, without any rewriting that could have occurred
        during expansion of the ancestor type's init proc, and we do not need
        to go back to Original_Node.

        * exp_ch3.ads (Expand_Derived_Record): Rename to
        Expand_Record_Extension.

        * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
        Returns the RACW type used to implement a remote access-to-subprogram
        type.
        (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
        New subprograms. Used to create a proxy tagged object for a remote
        subprogram. The proxy object is used as the designated object
        for RAS values on the same partition (unless All_Calls_Remote applies).
        (Build_Get_Unique_RP_Call): New subprogram. Build a call to
        System.Partition_Interface.Get_Unique_Remote_Pointer.
        (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
        Renamed from Add_RAS_*_Attribute.
        (Add_Receiving_Stubs_To_Declarations): Generate a table of local
        subprograms.
        New implementation of expansion for remote access-to-subprogram types,
        based on the RACW infrastructure.

        * exp_dist.ads (Copy_Specification): Update comment to note that this
        function can copy the specification from either a subprogram
        specification or an access-to-subprogram type definition.

2004-09-09  Ed Schonberg  <schonberg@gnat.com>

        * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
        in an instance, between an explicit subprogram an one inherited from a
        type derived from an actual.

        * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
        add a polling call if the subprogram is to be inlined by the back-end,
        to avoid repeated calls with multiple inlinings.

        * checks.adb (Apply_Alignment_Check): If the expression in the address
        clause is a call whose name is not a static entity (e.g. a dispatching
        call), treat as dynamic.

        * g-trasym.ads: Minor reformatting

        comparison.

        * opt.adb (Set_Opt_Config_Switches): Use Ada_Version_Runtime to compile
        internal unit.

        * opt.ads: Add Ada_Version_Runtime constant used to decide which
        version of the language is used to compile the run time.

2004-09-09  Arnaud Charlet  <charlet@act-europe.fr>

        * sem_util.adb (Requires_Transient_Scope): Re-enable handling
        of variable length temporaries for function return now that the
        back-end and gigi support it.

2004-09-01  Pascal Obry  <obry@gnat.com>

        * gprcmd.adb (Extend): Do not output trailing directory separator. This

        nominal subtype, pretend there is no initializer if the one we have is
        incomplete, and avoid referencing an inexistant component in there. The

        * snames.ads, snames.adb: Add standard name Metrics (name of project
        file package for gnatmetric).

        * vms_conv.ads: Add Metric to Comment_Type

        * vms_conv.adb (Initialize): Add component dor Metric in Command_List

2004-06-07  Thomas Quinot  <quinot@act-europe.fr>

        * bindgen.adb (Set_Unit_Number): Units is an instance of Table, and so
        the index of the last element is Units.Last, not Units.Table'Last
        (which is usually not a valid index within the actually allocated
        storage for the table).

        * exp_ch4.adb (Insert_Dereference_Action): Change predicate that
        determines whether to generate a call to a checked storage pool
        Dereference action.
        Generate such a call only for a dereference that either comes from
        source, or is the result of rewriting a dereference that comes from
        source.

2004-06-07  Romain Berrendonner  <berrendo@act-europe.fr>

        * bindgen.adb (Gen_Output_File): Add support for GAP builds.

2004-06-07  Eric Botcazou  <ebotcazou@act-europe.fr>

2004-06-07  Hristian Kirtchev  <kirtchev@gnat.com>

        * lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
        includes case of a variable referenced on the left hand side of an
        assignment, therefore remove redundant code. Variables and prefixes of
        indexed or selected components are now marked as referenced on left
        hand side. Warnings are now properly emitted when variables or prefixes
        are assigned but not read.

        * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
        left hand side referenced variables. Private access types do not
        produce the warning "variable ... is assigned but never read".
        Add also additional checks to left hand side referenced variables.
        Aliased, renamed objects and access types do not produce the warning
        "variable ... is assigned but never read" since other entities may read
        the memory location.

        Removes spurious type errors from g-trasym-vms.adb.

        * sem_res.adb (Rewrite_Renamed_Operator): If intrinsic operator is
        distinct from the operator appearing in the source, call appropriate
        routine to insert conversions when needed, and complete resolution of
        node.

        interpretations for rewritten right operand.
        (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

        * exp_ch4.adb (Expand_N_Type_Conversion,
        Expand_N_Unchecked_Type_Conversion): Special handling when target type
        is Address, to avoid typing anomalies when Address is a visible integer
        type.

        * exp_ch6.adb (Expand_N_Subprogram_Body): Use Is_Descendent_Of_Address
        to determine whether a subprogram should not be marked Pure, even when
        declared in a pure package.

        * gnat_ugn.texi: Replace pragma Ravenscar by pragma Profile.

        * gnat_rm.texi: Replace Max_Entry_Queue_Depth by Max_Entry_Queue_Length
        Document No_Dynamic_Attachment, that supersedes No_Dynamic_Interrupts.
        Update the documentation about the Ravenscar profile, following the
        definition found in AI-249.

        * sem_prag.adb: Use FIFO_Within_Priorities and Ceiling_Locking when
        setting the Profile (Ravenscar). This must be done in addition to

        in -2.0**32 .. 2.0**32.
        (Cos, Sin):  Always reduce arguments of 1/4 Pi or larger, to prevent
        reduction by the processor, which only uses a 68-bit approximation of
        Pi.

        the processor's fptan instruction, or by dividing sin and cos as needed.

        * g-os_lib.adb (Normalize_Pathname.Final_Value): Remove trailing
        directory separator.

        * prj-proc.adb (Recursive_Process): Inherit attribute Languages from
        project being extended, if Languages is not declared in extending
        project.

2004-05-14  Robert Dewar  <dewar@gnat.com>

        * gnat_ugn.texi: Minor change to -gnatS documentation

        * sprint.adb: Remove some instances of Assert (False) and for this
        purpose replace them by output of a ??? string.

        * checks.adb, exp_aggr.adb, sem_elim.adb: Remove useless pragma
        Assert (False).

        * lib-writ.adb, lib-load.adb, lib.ads, lib.adb: Remove Dependent_Unit
        flag processing. This was suppressing required dependencies in
        No_Run_Time mode and is not needed since the binder does not generate
        references for things in libgnat anyway.

        * sem_ch3.adb (Access_Type_Declaration): Reorganize code to avoid GCC
        warning.

2004-05-14  Thomas Quinot  <quinot@act-europe.fr>

        subtype, check visible entities in base type.

        * exp_ch7.adb (Clean_Simple_Protected_Objects): Do not generate cleanup
        actions if the object is a renaming.

        * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
        Check_Formal_Package_Instance, to determine more precisely when the
        formal and the actual denote the same entity.

2004-05-14  Javier Miranda  <miranda@gnat.com>

        * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262

        * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
        corresponding to a private_with must be removed from visibility; it
        will be made visible later, just before we analyze the private part of
        the package.
        (Check_Private_Child_Unit): Allow private_with clauses in public
        siblings.
        (Install_Siblings): Make visible the private entities of private-withed
        siblings.
        (Install_Withed_Unit): Do not install the private withed unit if we
        are compiling a package declaration and the Private_With_OK flag was
        not set by the caller. These declarations will be installed later,
        just before we analyze the private part of the package.

        * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
        during the evaluation of the expression that initializes the object,
        decorate it with the expected type to avoid cascade errors.
        Code cleanup.

        * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
        subprogram we have to install the private_with clauses after its
        specification has been analyzed (as documented in AI-262.TXT).

        * sem_ch8.adb (Has_Private_With): New function. Determines if the
        current compilation unit has a private with on a given entity.
        (Find_Direct_Name): Detect the Beaujolais problem described in
        AI-262.TXT

        * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
        provides the functionality of the function Is_Ancestor that was
        previously available in sem_ch10. It has been renamed to avoid
        overloading.

        * sprint.adb (Sprint_Node_Actual): Print limited_with clauses

2004-05-14  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

        * utils.c (build_vms_descriptor): Use SImode pointers.

        executable name when not initialized. Otherwise, use its current value.

        * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
        initialize it to another executable name than the current one. This
        allows to configure paths for an executable name (gnatmake) different
        from the current one (gnatdist).

2004-03-29  Ed Schonberg  <schonberg@gnat.com>

        * exp_ch6.adb (Expand_Call): A call to a function declared in the

        unit, to avoid order of elaboration problems in gigi.

        * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
        information for protected (wrapper) operation as well, to simplify gdb
        use.

        from source, to ensure that references are properly generated for it.
        (Build_Body_To_Inline): Do not inline a function that returns a

        apply convention to homonyms that are declared explicitly.

        * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
        that renames an equality operator and the operands are overloaded,

2004-03-25  Thomas Quinot  <quinot@act-europe.fr>

        * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
        attribute reference does not denote a subtype, it can be any
        expression that has a classwide type, potentially after an implicit
        dereference.  In particular, the prefix can be a view conversion for
        a classwide type (for which Is_Object_Reference holds), but it can
        also be a value conversion for an access-to-classwide type. In the
        latter case, there is an implicit dereference, and the original node
        for the prefix does not verify Is_Object_Reference.

        * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
        conversion of a discriminant-dependent component of a mutable object
        is one itself.

        than the original subprogram.

        * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
        indication on renaming declaration, if formal has a box and actual
        is absent.

        * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
        determine whether to generate an implicit or explicit reference to
        the renamed entity.

        * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
        subprogram renaming comes from a defaulted formal subprogram in an
        instance.

2004-03-25  Gary Dismukes  <dismukes@gnat.com>

        * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
        value expressions to ensure that calls within a component definition
        will be checked (since those are evaluated during the record type's
        elaboration).

        get_action_description_for, and expanded to take care of the VMS
        specifities.

        (Expand_N_Slice): Same. Always do the rewriting, even for the case
        of non-packed slices, since the dereference action generated by
        expansion of the explicit dereference is needed in any case.

        analyze and resolve the rewritten explicit dereference so it is seen
        by the expander.

        expansion of an N_Explcit_Dereference_Node. Do insert a check even for
        dereferences that do not come from source (including explicit

        Don't make a bitfield if the field is to be addressable.
        Always set a size for the field if the record is packed, to ensure the

        In case of default initialized aggregate with tasks this parameter is
        used to generate a null string (this is just a workaround that must be

        * gnat-style.texi (header): Add @dircategory, @direntry.
        (title page): Remove date.
        (general) Add @./@: where approriate, and two spaces after the
        full stop at the end of a sentence.  Use @samp markup when
        referring concrete lexical entities (keywords, attribute names
        etc.), and @syntax for ARM grammar elements. Use @r for English
        text in comments.  Use @emph for emphasis.  Change "if-statements"

        * make.adb (Add_Switch): Make Generic_Position a procedure.  The
        function approach did not work well because of a side effect (the
        function call could reallocate the table which was being indexed
        using its result). Fixes ada/4851.

        * raise.c (__gnat_eh_personality): Exception handling personality
        routine for Ada.  Still in rough state, inspired from the C++ version

        Add 2001 to copyright date

        * g-regpat.adb: Change pragma Inline_Always to Inline. There is no

2001-12-17  Laurent Pautet <pautet@gnat.com>

        * g-socket.ads:
        Fix comment of Shutdown_Socket and Close_Socket. These functions
        should not fail silently because if they are called twice, this
        probably means that there is a race condition in the user program.
        Anyway, this behaviour is consistent with the rest of this unit.
        When an error occurs, an exception is raised with the error message
        as exception message.

        (CRC_Error): new constant.

        * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
        a CRC now and not a simple checksum. A CRC uses lower-case hex
        letters, fixes ambiguity in parsing.

        * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
        is what this variable will store.

        * bcheck.adb: Change reference to chechsum in comments by CRC.
        (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
        rename All_Checksum_Match to All_CRC_Match. Change due to API
        renaming since now GNAT does not use a simple checksum but a
        CRC using GNAT.CRC32.

        * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
        now and not anymore a simple checksum.

        places.

        * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.

        (Restore_Scan_State): rename Checksum to CRC.
        (Save_Scan_State): idem.

        * scans.ads:
        With GNAT.CRC32.
        (Checksum): rename to CRC.
        (Saved_Scan_State): Save_Checksum field renamed to Save_CRC

        * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from

        GNAT.CRC32).  Update copyright notice.

        * scn.adb:
        (Accumulate_Checksum): removed.
        (Update): new procedure. Add a wide-character into the CRC.

        * sinput-l.adb:
        (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
        (Load_File): fix initialization of S (change Source_Checksum to
        Source_CRC)

        * sinput-p.adb (Load_Project_File): rename Source_Checksum to
        Source_CRC in S initialization.

        * sinput.adb (Source_Checksum): renamed to Source_CRC.

        * sinput.ads (Source_Checksum): renamed to Source_CRC.
        Update comments for the CRC.

        * types.adb (Hex): Use lowercase for the letter part.

        * types.ads (Get_Hex_String): Returns the hexadecimal representation
        for a word. This is currently used only for CRC. In previous version,
        the checksum was using a representation with all letter being
        upper-case. With the new implementation (using CRC) we do not remove
        the 32th bit of the CRC, so we can have an upper-case starting letter
        in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
        It is ambigous since the CRC was optional and could be followed by
        options like EB, EE. So now this routines uses lower-case letter for
        the hexadecimal representation. Strange enough only lower case letters
        where checked in Scan_ALI (even if this was not a possible case).

        * gnatvsn.ads (Library_Version): changed to 3.15a.

        * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
        for the compiler.

        * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
        for the compiler.

        * ali-util.adb: Redo previous change to avoid using word CRC everywhere
        Add 2001 to copyright notice
        (Accumulate_Checksum): Modify to use System.CRC32.

        * ali-util.ads: Redo changes of previous revision to continue to use
        the word Checksum. Add 2001 to copyright notice.

        * ali.adb: Undo some of previous changes, not needed.
        Keep the change for lower case letters in the checksum.

        * ali.ads: Undo previous change not needed.

        * bcheck.adb: Undo most of previous change, not needed.
        But do use Checksums_Match for checksum comparison.

        * gnatls.adb: Undo most of previous change, not needed.
        But do use Checksums_Match for comparing checksums.

        * lib-load.adb: Undo previous change, not needed.

        * lib-writ.adb: Undo previous change, not needed.

        * lib-writ.ads: Document that checksums use lower case,
        not upper case letters.

        * scans.adb: Undo previous change, not needed

        * scans.ads: Undo previous change, not needed.

        * scn-nlit.adb: Undo previous changes, not needed.

        * scn.adb:
        (Accumulate_Checksum): Use System.CRC32.

        * sinput-l.adb: Undo previous change, not needed.

        * sinput.ads: Undo previous change, not needed.  Keep only comment
        on new checksum algorithm

        * Makefile.in: Add s-crc32 as needed, remove g-crc32.
        Also remove a-tags and a-stream from GNAT sources.

        * ali.adb (Scan_ALI): fix typo introduce in latest check-in.

        * Makefile.in (GNATRTL_NONTASKING_OBJS): Add g-crc32.o.
