2595 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2596 Orig_Prev to Prev in the case where the actual is N_Function_Call or
2597 N_Identifier. This was interfering with other cases that are rewritten

4686 which is the default in GNAT's persistent storage implementation.
4688 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4691 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4692 convention from its base type, do not set the type to that of integer,
4693 because it may inherit a size clause.

4735 (P_Access_Definition): Change the error message when parsing "access
4736 all" in Ada 95 mode. The message no longer forces the user to recompile

4757 the visible part of the spec of a remote types unit.

4759 New local subprogram Is_Valid_Remote_Object_Type, replaces
4760 Is_Recursively_Limited_Private.
4761 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4762 non-controlling formals (and the return type, even though this is not
4763 explicit in the standard) must support external streaming.
4764 (Validate_RCI_Subprogram_Declaration): Enforce E.2.3(14) rules: same
4765 as above for of RAS types and RCI subprograms. (The return type is not

4770 * sem_util.ads, sem_util.adb
4771 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4772 Is_Remote_Call_Interface to identify RACW types in a stable and
4773 consistent way. We used to rely in this predicate on the privateness of
4774 the designated type and its ancestors, but depending on the currently
4775 visible private parts, this caused false negatives. We now uniformly
4776 rely on checks made at the point where the RACW type is declared.

4790 Add missing escaping of all-caps word 'CPP' in error messages.
4791 (Build_Discriminated_Subtype): Do not inherit representation clauses
4792 from parent type if subtype already carries them, because they are
4793 inherited earlier during derivation and already include those that may
4794 come from a partial view.
4796 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4797 Check the declarations of a subprogram body for proper deferred

4831 (Add_One_Interp): Ignore any interpretation that is a primitive
4832 operation of an RACW stub type (these primitives are only executed
4833 through dispatching, never through static calls).
4834 (Collect_Interps): When only one interpretation has been found, set N's
4835 Entity and Etype to that interpretation, otherwise Entity and Etype may
4836 still refer to an interpretation that was ignored by Add_One_Interp,
4837 in which case would end up with being marked as not overloaded but with
4838 an Entity attribute not pointing to its (unique) correct interpretation.
4840 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4843 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

4853 (Print_Itype): Do not modify the sloc of the component type of a
4854 (packed) array itype, because it is an unrelated type whose source
4855 location is independent of the point of creation of the itype itself.
4857 2008-05-20 Thomas Quinot <quinot@adacore.com>

4894 2008-05-20 Arnaud Charlet <charlet@adacore.com>

4897 equivalent representation, but has the advantage of allowing
4898 compilation of this file under 64 bits platforms.

9097 subprogram body that acts as its own spec may not have a non-private
9098 WITH clause on a private sibling.
9099 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
9100 child unit is a renaming, create an implicit with_clause on that
9101 parent, and not on the unit it renames, to prevent visibility errors

9168 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
9169 type from a limited_with_clause, and the full view is available, use it

9198 Gary Dismukes <dismukes@adacore.com>
9200 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
9201 requeue statement is dispatching. Do not emit an error when the name is

9203 perform subtype conformance between the formals of the current entry
9204 and those of the target interface primitive.
9205 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
9206 Timed_Entry_Call): Analyze the triggering statement as the first step of
9207 the processing. If this is a dispatching select, postpone the analysis
9208 of all select statements until the Expander transforms the select. This

9210 replicated some of the select statements. In case the Expander is
9211 disabled, perform regular analysis.
9212 (Check_Triggering_Statement): New routine.
9213 (Analyze_Requeue): Exclude any interpretations that are not entries when
9214 checking overloaded names in a requeue. Also test type conformance for
9215 matching interpretations rather than requiring subtype conformance at
9216 that point to conform with the RM's resolution rule for requeues.

9223 for the defaulted actual.
9225 2007-12-13 Geert Bosch <bosch@adacore.com>
9227 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

9252 latest Ada 2005 rules about renaming and 'Access of
9253 discriminant-dependent components.

9810 multiple inherited interfaces info. This information cannot be stored
9811 in Xref_Entity_Record, which only supports a single instance of Tref_*,

9828 additional management on these nodes in Expand_Interface_Actuals.
9830 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9831 that handles use of 'Access and 'Unchecked_Access applied to

9877 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info

9879 able to extract the stack boundaries for stack checking.

9923 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9924 association for an access component, add an association with null as
9925 the expression. Remove testing for array subtypes and the setting in
9926 that case of Ctyp to the array component type, which prevented proper
9927 inclusion of an association for null-initialized arrays. Collapse
9928 condition that tests for array subtypes into just a test of
9929 Is_Partially_Initialized_Type (which already covers arrays anyway).

9946 * sem_ch4.adb: Minor code and comment reformatting.
9947 (Analyze_Allocator): When the designated type of an unconstrained

10087 source location into mapped location.
10088 (annotate_with_node): Rename into set_expr_location_from_node.
10089 Call set_expr_location instead of annotate_with_locus.
10090 (Pragma_to_gnu): Adjust for above change.
10091 (Loop_Statement_to_gnu): Likewise.

10115 Add a section on leap seconds control along with two entities used to
10116 enable and disable leap seconds support. The array Leap_Second_Times is
10117 now constant and contains hard time values pre-generated. Remove
10118 all elaboration code used to populate the table of leap seconds.
10121 Add entity Leap_Seconds_Support to the list of global run-time variables
10122 along with a comment on its usage and values.
10123 (Gen_Adainit_Ada): Add code to generate the declaration and import of
10124 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
10125 or one (enabled) depending on the presence of binder switch "-y".

10140 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
10142 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
10143 function which can be called by the debugger to interrupt the tasks of
10144 an Ada application asynchronously, as needed on VxWorks.
10145 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
10147 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
10148 renamed from Stop_All_Tasks. Update comments.
10149 (Stop_All_tasks): New function declaration.
10151 2007-09-26 Olivier Hainque <hainque@adacore.com>
10153 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around

10176 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
10178 2007-09-26 Javier Miranda <miranda@adacore.com>
10179 Eric Botcazou <ebotcazou@adacore.com>
10182 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
10183 indirection added to the HT_Link component of the TSD. This is required
10184 to statically allocate the TSD.
10187 Minor reordering of the declarations in the private part. Required to
10188 add a level of indirection to the contents of the TSD component HT_Link.
10189 This is required to statically allocate the TSD.
10191 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
10192 Is_Statically_Allocated set from constant objects.
10193 Do not make exported constants created by the compiler volatile.
10194 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
10197 * trans.c (Identifier_to_gnu): For constants, unshare initializers
10198 before returning them.
10200 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
10201 public part of the package.
10202 (Make_DT): Move HT_Link component out of the TSD record. For this
10203 purpose Make_DT now declares a separate object that stores the
10204 HT_Link value, and initializes the TSD component with the address
10205 of this new object. The addition of this level of indirection is
10206 required to statically allocate the TSD because the TSD cannot
10207 have variable components.
10208 (Expand_Interface_Conversion): Improve the expanded code.
10209 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
10211 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
10212 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
10213 if we are building static dispatch tables then we must not generate
10214 extra code to register the primitive because the dispatch table will
10215 be built at the end of the library package; otherwise we notify that
10216 we cannot build the static dispatch table.
10218 2007-09-26 Robert Dewar <dewar@adacore.com>
10220 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

10235 for thunks associated with interface types.
10237 * einfo.ads: Improve documentatation of Is_Internal
10238 (Is_Thunk): New attribute applicable to subprograms. True for thunks
10239 associated with interface types.
10240 Extensive comment fixes regarding flags that appear in all entities. The
10241 documentation is now consistent for all such flags (there were a number
10242 of errors in the documentation in this regard).
10244 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
10246 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
10247 of these procedures are passed a function call that already has
10248 build-in-place actuals (testing new flag
10249 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
10250 the case where processing continues.
10251 (Expand_Call): If the call is generated from a thunk body then we
10252 propagate the extra actuals associated with the accessibility
10253 level of the access type actuals.
10255 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
10256 of each extra formal of a protected operation to reference the
10257 corresponding extra formal of the subprogram denoted by the
10258 operation's Protected_Body_Subprogram.
10260 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
10261 N_Function_Call nodes.
10263 2007-09-26 Robert Dewar <dewar@adacore.com>

10271 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
10272 debug variable so that it won't be initialized when pragma
10273 Initialize_Scalars is in effect.
10275 2007-09-26 Gary Dismukes <dismukes@adacore.com>
10277 * freeze.adb (Freeze_Entity): Remove check for preelaborable
10278 initialization of a full view. This is moved to
10279 Analyze_Package_Specification.
10281 * sem_ch7.adb (Analyze_Package_Specification): Add check for
10282 preelaborable initialization of a full view in entity loop.
10283 (Uninstall_Declarations): If entity is a use-visible compilation unit,
10284 its child units are use-visible only if they are visible child units.
10286 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
10287 whether an expression can be used within a type declaration that
10288 requires preelaborable init.
10289 (Check_Components): Replace inline code that does partial checking for
10290 preelaborable default expressions with call to
10291 Is_Preelaborable_Expression.
10292 (Has_Preelaborable_Initialization): In the case of a generic actual
10293 subtype, (that is, Is_Generic_Actual is True), return the result of
10294 applying Has_Preelaborable_Initialization to the generic actual's base
10297 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
10299 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
10300 call to Jan_1_Day _Of_Week to optimize its performance.
10301 (Is_Leap): Move the routine to the scope of Week_In_Year.
10302 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
10303 weekday on which January 1 falls of Year - 1 and Year + 1. This function
10304 avoids calling Time_Of and Split, thus making it more efficent.
10305 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
10307 * g-calend.ads (Week_In_Year): Change comment to reflect new
10310 2007-09-26 Emmanuel Briot <briot@adacore.com>
10312 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
10313 Command_Line): New types
10314 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
10315 support for defining how switches can be grouped on a command line (as
10316 is the case for -gnatw... for GNAT), and how simple switches can be
10317 used as aliases for more complex switches (-gnatwa is same as
10319 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
10320 (Start, Current_*): New subprograms
10321 Added support for parsing an array of strings in addition to the real
10323 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
10324 be moved from the body to the private part of the spec.
10325 (*): All subprograms now have an extra parameter with default value to
10326 specify which parser should be used. For backward compatibility, it
10327 defaults to parsing the command line of the application. They were also
10328 modified to properly handle cases where each of the argument does not
10329 start at index 1 (which is always true for Ada.Command_Line, but not
10330 when processing any Argument_List).
10331 (Free): New subprogram
10332 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
10333 Argument): New subprograms
10334 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
10335 special characters like ':', '=',... are now handled in a single place,
10336 which makes the code more extensible eventually.
10337 (Getopt, Full_Switch): When the switch was returned as part of the
10338 special character '*', make sure it is prepended by the switch character
10339 ('-' in general), so that the application knows whether "foo" or "-foo"
10340 was specified on the command line.
10342 2007-09-26 Florian Villoing <villoing@adacore.com>
10344 * g-dirope.adb (Remove_Dir): In case we are removing directories
10345 recursively, make sure that if an exception is raised during the
10346 processing, the current working directory is reset to its initial
10347 value before propagating the exception.
10349 2007-09-26 Vincent Celier <celier@adacore.com>
10351 * gnatbind.adb: If there are several ALI files specified and there is
10352 a main program to bind, the first ALI is expected to contain the main
10353 subprogram and the names of the binder generated files will be derived
10354 from the first ALI file name.
10355 (Gnatbind): Fix insertion character in invocation of Error_Msg
10357 2007-09-26 Vincent Celier <celier@adacore.com>
10359 * gnatcmd.adb (Check_Files): Do not include sources that have been
10360 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
10362 2007-09-26 Ed Schonberg <schonberg@adacore.com>
10364 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
10365 information about each of its index types, following the type
10366 reference for its component type.
10368 2007-09-26 Vincent Celier <celier@adacore.com>
10370 * make.adb: (Kill): New procedure (__gnat_kill imported)
10371 (Running_Compile, Outstanding_Compiles): Global variables that
10372 were previously local to procedure Compile_Sources.
10373 (Sigint_Intercepted): Send signal SIGINT to all outstanding
10374 compilation processes.
10376 (Gnatmake): If project files are used, create the mapping of all the
10377 sources, so that the correct paths will be found.
10379 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
10381 2007-09-26 Vincent Celier <celier@adacore.com>

10401 being extended, instead of a shallow copy.
10402 (Process_Project_Tree_Phase_1): New procedure

10422 message to cite use of <> in aggregate component associations rather
10423 than wrongly indicating use of limited aggregates.

10427 * sem_attr.adb (Analyze_Access_Attribute): Fix missing set of
10430 2007-09-26 Ed Schonberg <schonberg@adacore.com>
10432 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
10433 ancestor of the derived type, the operations are inherited from the
10434 primary dispatch table of the parent.
10435 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
10436 when the context is an explicit type conversion.
10438 2007-09-26 Ed Schonberg <schonberg@adacore.com>

10446 * sem_res.adb (Resolve_Call): If the call is dispatching, generate the
10447 proper kind of reference to the primitive operation, for better source
10449 (Valid_Conversion): A tagged conversion is legal if both operands are
10452 2007-09-26 Robert Dewar <dewar@adacore.com>

10472 Add qualified for the new gnatbind option '-y'
10474 * gnat_ugn.texi: Revise the gnatmetric section.
10475 Add entry for new gnatbind option '-y'.

10738 potentially be called.
10739 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10740 body for 'Output when the type is abstract (only the creation of the
10741 body for 'Input is excluded when the type is abstract).

10743 statement, so that False will be returned for TTS_Stream_Input if the
10744 associated tagged type is an abstract extension. Add comments for
10746 (Expand_N_Object_Declaration): For the case of a shared passive
10747 variable, insert init proc call only after the shared variable
10748 procedures have been processed, because the IP call needs to undergo
10749 shared passive variable reference expansion, which requires these

10762 type, retrieve its value from the aggregate itself, where it must have
10765 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10766 to remove other spurious ambiguities on arithmetic operations involving
10767 literals and addresses, on systems where Address is a visible integer
10768 type, when the operator is called in functional notation.
10769 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10770 is legal when the types match, even if the operation is currently

10896 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10897 spurious ambiguities when integer literals appear in the context of an
10898 address type that is a visible integer type.
10900 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10901 exceptions never being raised.
10902 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

10918 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10919 library-level package renaming, pass the declaration associated with
10920 the renaming's special debug variable to Qualify_Entity_Names to ensure
10921 that its encoded name is properly qualified.
10923 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10924 occurring in the list of entities to qualify, and do not attempt to
10925 traverse an entity list in that case. Variables associated with
10926 ` library-level package renamings can now occur in the table.
10928 * exp_dbug.ads: Revise documentation of the encoding for renaming

10950 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10951 concatenations of string literals into a single literal, in order to
10952 avoid very deep recursion in the front end, which was causing stack
10955 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10956 string, and the right operand is a string literal (the case of "" &
10957 "..."), optimize by avoiding copying the right operand -- just use the
10958 value of the right operand directly.
10960 * stringt.adb (Store_String_Chars): Optimize by growing the
10961 String_Chars table all at once, rather than appending characters one by
10963 (Write_String_Table_Entry): If the string to be printed is very long,
10964 just print the first few characters, followed by the length. Otherwise,
10965 doing "pn(n)" in the debugger can take an extremely long time.
10967 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10968 Store_String_Char with Store_String_Chars.

10981 * sem_ch10.adb (Analyze_Subunit_Context): When analyzing context
10982 clauses of subunits, ignore limited_with_clauses that are illegal and
10983 have not been fully analyzed.
10985 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10987 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10988 flag, for effiency. It is called when analyzing arithmetic operators
10989 and also for actuals in calls that are universal_integers. The flag is
10990 set for the predefined type address, and for any type or subtype
10993 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10994 Universal_Integer, when the formal is a descendent of address and the
10995 call appears in user code.
10996 (Analyze_Selected_Component): if the prefix is a private extension, the
10997 tag component is visible.

11060 2007-08-16 Gary Dismukes <dismukes@adacore.com>
11062 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
11063 associated with Standard_Debug_Renaming_Type, to be used as the type of
11064 the special variables whose names provide debugger encodings for
11065 renaming declarations.
11067 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
11068 (Set_Debug_Renaming_Link): Change to set Node25.

11075 (Debug_Renaming_Declaration): Replace creation of an enumeration type
11076 and literal with creation of a variable of type
11077 Standard_Debug_Renaming_Type whose name encodes both the renamed object
11078 and the entity of the renaming declaration.
11079 (Qualify_Entity_Name): Add the delayed qualification of the entity name
11080 part of the name of a variable that has a Debug_Renaming_Link.
11082 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
11083 special type to be associated with variables that provide debugger
11084 encodings for renaming declarations.

11087 Ed Schonberg <schonberg@adacore.com>
11088 Javier Miranda <miranda@adacore.com>
11090 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
11091 ancestor part given by an aggregate to test for an unchecked conversion,
11092 since this can occur in some cases when the ancestor part is a function
11093 call, and we don't want to fall into the recursive call to this
11094 procedure in that case.
11096 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
11097 stream attributes on limited types to account for user-specified
11098 attributes as well as whether Input (resp. Output) becomes available
11099 due to Read (resp. Write) being available for the type. Change Boolean
11100 variable to the more accurate name
11101 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
11102 double-"not" predicate at beginning of return statement to more
11103 understandable form.
11105 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
11106 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
11107 in a block statement and use that as the first statement of the
11108 expanded return rather than incorrectly using the handled sequence as
11109 the first statement.
11111 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
11112 operation, generate an explicit freeze node for it rather than
11113 generating extra formals, to ensure that gigi has the proper order of
11114 elaboration for anonymous subtypes in the signature of the subprograms.
11115 (Build_In_Place_Formal): Move assertion to beginning of loop.
11116 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
11117 applied to a function call (occurs for some cases of 'Input).

11119 applied to a function call (occurs for some cases of 'Input).
11121 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
11122 2005, generate an extended return statement enclosing the result object
11125 * freeze.adb (Freeze_Record_Type): Extend the current management of
11126 components that are access type with an allocator as default value: add
11127 missing support to the use of qualified expressions of the
11128 allocator (which also cause freezing of the designated type!)
11129 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
11130 dispatching operation, since extra formals may be needed by calls to
11131 build-in-place functions (such as stream 'Input).
11133 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
11134 formals for 'Constrained and accessibility level in the case of a
11135 predefined dispatching operation.
11137 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
11138 point, no need to find the parent node.
11140 2007-08-16 Javier Miranda <miranda@adacore.com>
11142 * exp_attr.adb (Attribute_Priority): Add missing support for entries
11143 and entry barriers.
11145 2007-08-16 Javier Miranda <miranda@adacore.com>
11147 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
11148 is not really required and can introduce regression with the debugger.
11149 The original problem is fixed with the patch written for checks.adb.
11151 2007-08-16 Thomas Quinot <quinot@adacore.com>
11153 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

11160 (Gnatmake): For the compiler, call Test_If_Relative_Path with
11161 Including_Non_Switch set to False.
11163 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
11164 parameter Including_Non_Switch, defaulted to True. When
11165 Including_Non_Switch is False, options that are not switches and
11166 appear as relative path are not converted to absolute paths.
11168 2007-08-16 Nicolas Roche <roche@adacore.com>
11170 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

11177 * sem_ch10.adb (Has_With_Clause): If the name of the with clause
11178 currently inspected is a selected component, retrieve the entity of
11180 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
11181 from the immediate ancestor of Main_Unit_Entity.
11182 (Install_Limited_Withed_Unit): Do not install the limited view of
11183 package P if P is reachable through an ancestor chain from package C
11184 and C also has a with clause for P in its body.
11185 (Has_Limited_With_Clause): New routine.
11186 (Has_With_Clause): New routine.
11188 2007-08-16 Ed Schonberg <schonberg@adacore.com>
11190 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
11191 generic for an enclosing instance is a global reference, even though
11192 its scope is the enclosing instance.
11194 2007-08-16 Gary Dismukes <dismukes@adacore.com>
11195 Javier Miranda <miranda@adacore.com>
11197 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
11198 initialize a limited object.
11199 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
11201 Make sure Has_Complex_Representation is inherited by derived type.
11203 2007-08-16 Robert Dewar <dewar@adacore.com>
11205 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
11208 2007-08-16 Ed Schonberg <schonberg@adacore.com>
11210 * sem_disp.adb (Check_Dispatching_Operation): If the operation
11211 implements an operation inherited from a progenitor interface, verify
11212 that they are subtype-conformant.
11214 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
11215 Bob Duff <duff@adacore.com>
11216 Nicolas Setton <setton@adacore.com>
11218 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
11219 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
11220 the statement which is being resolved comes from a predefined library
11221 unit, all non-predefined library interpretations are skipped.
11222 (Resolve_Op_Concat): If string concatenation was folded in the parser,
11223 but the "&" is user defined, give an error, because the folding would
11226 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
11227 the parser has folded a long sequence of concatenations of string
11230 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
11231 and "JMP_BUF" variables as artificial.
11232 (N_String_Literal): Do not use alloca for very long string literals. Use
11233 xmalloc/free instead. Otherwise the stack might overflow.
11235 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the

11280 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
11281 Suppress unmodified in-out parameter warning in some cases
11282 This patch is a also fairly significant change to the way suppressible
11283 checks are handled.
11285 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
11286 needed for access to concurrent record types generated by the expander.
11287 (Generate_Range_Check): When generating a temporary to capture the
11288 value of a conversion that requires a range check, set the type of the
11289 temporary before rewriting the node, so that the type is always
11290 properly placed for back-end use.
11291 (Apply_Float_Conversion_Check): Handle case where the conversion is
11293 (Get_Discriminal): Code reformatting. Climb the scope stack looking

11309 (Expand_N_Type_Conversion): Test for the case of renamings of access
11310 parameters when deciding whether to apply a run-time accessibility
11312 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
11313 aggregate code before allocator, and ahead of declaration for
11314 temporary, to prevent access before elaboration when the allocator is
11315 an actual for an access parameter.
11316 (Expand_N_Type_Conversion): On an access type conversion involving an
11317 access parameter, do not apply an accessibility check when the
11318 operand's original node was an attribute other than 'Access. We now
11319 create access conversions for the expansion of 'Unchecked_Access and
11320 'Unrestricted_Access in certain cases and clearly accessibility should
11321 not be checked for those.
11323 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
11324 includes a type conversion of a packed component that has been expanded,
11325 recover the original expression for the object, and use this expression
11326 in the post-call assignment statement, so that the assignment is made
11327 to the object and not to a back-end temporary.
11328 (Freeze_Subprogram): In case of primitives of tagged types not defined
11329 at the library level force generation of code to register the primitive
11330 in the dispatch table. In addition some code reorganization has been
11331 done to leave the implementation clear.
11332 (Expand_Call): When expanding an inherited implicit conversion,
11333 preserve the type of the inherited function after the intrinsic
11334 operation has been expanded.
11336 * exp_ch2.ads, exp_ch2.adb
11337 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
11338 of an entry formal appearing in an assignment statement does not assign
11340 (Expand_Current_Value): Instead of calling a routine to determine
11341 whether the prefix of an attribute reference should be optimized or
11342 not, prevent the optimization of such prefixes all together.
11344 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
11345 component whose prefix is known to be of an access type is an implicit
11346 dereference and does not assign to the prefix.
11348 2007-08-14 Ed Schonberg <schonberg@adacore.com>

11354 Add comments and correct harmless error in Build_NCT_Hash_Tables
11355 (Array_Aggr_Subtype): Associate each itype created for an index type to
11356 the corresponding range construct, and not to the aggregate itself. to

11358 node, to prevent errors when complex expression is copied.
11359 Fix mishandling of multiple levels of parens
11361 * sem_aggr.adb: Create a limited view of an incomplete type, to make
11362 treatment of limited views uniform for all visible declarations in a
11363 limited_withed package.
11364 (New_Copy_Tree): If hash table is being used and itype is visited,
11365 make an entry into table to link associated node and new itype.
11366 (Resolve_Record_Aggregate): Do not add an others box association for a
11367 discriminated record component that has only discriminants, when there
11368 is a box association for the component itself.

11417 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
11418 generation of a freezing node to ensure proper management of null
11419 excluding access types in the backend.
11420 (Create_Extra_Formals): Test base type of the formal when checking for
11421 the need to add an extra accessibility-level formal. Pass the entity E
11422 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
11423 originally being done in a couple of cases), to ensure that the
11424 Extra_Formals list gets set on the entity E when the first entity is
11426 (Conforming_Types): Add missing calls to Base_Type to the code that
11427 handles anonymous access types. This is required to handle the
11428 general case because Process_Formals builds internal subtype entities
11429 to handle null-excluding access types.
11430 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11431 functions that need it, even when not marked Requires_Overriding.
11432 Improve warnings for in out parameters
11433 (Analyze_Function_Return): Warn for disallowed null return
11434 Warn on return from procedure with unset out parameter
11435 Ensure consistent use of # in error messages
11436 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
11437 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
11438 the implicit conversion of the expression done for anonymous access
11439 types. This is required to generate the code of the null excluding
11440 check (if required).
11442 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
11443 A formal parameter is never publicly referenceable outside of its body.
11444 (Check_References): For an unreferenced formal parameter in an accept
11445 statement, use the same warning circuitry as for subprogram formal
11447 (Warn_On_Unreferenced_Entity): New subprogram, taken from
11448 Output_Unreferenced_Messages, containing the part of that routine that
11449 is now reused for entry formals as described above.

11451 (Check_References): Do not give IN OUT warning for dispatching operation
11452 Improve warnings for in out parameters

11460 Gary Dismukes <dismukes@adacore.com>
11462 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
11463 (Expand_N_Attribute_Reference): Further unify the handling of the
11464 three forms of access attributes, using common code now for all three
11465 cases. Add a test for the case of applying an access attribute to
11466 an explicit dereference when the context is an access-to-interface
11467 type. In that case we need to apply the conversion to the prefix
11468 of the explicit dereference rather than the prefix of the attribute.
11469 (Attribute_Version, UET_Address): Set entity as internal to ensure
11470 proper dg output of implicit importation.
11471 (Expand_Access_To_Type): Removed.
11472 (Expand_N_Attribute_Reference): Merge the code from the three cases
11473 of access attributes, since the processing is largely identical for
11474 these cases. The substantive fix here is to process the case of a
11475 type name prefix (current instance case) before handling the case
11476 of interface prefixes.

11481 Robert Dewar <dewar@adacore.com>
11483 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
11484 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
11485 type that is an anonymous access to controlled object, establish
11486 an associated finalization chain to avoid corrupting the global
11487 finalization list when a dynamically allocated object designated
11488 by such a component is deallocated.
11489 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11490 functions that need it, even when not marked Requires_Overriding.
11491 (Initialize_Tag): Replace call to has_discriminants by call to
11492 Is_Variable_Size_Record in the circuitry that handles the
11493 initialization of secondary tags.
11494 (Is_Variable_Size_Record): New implementation.
11495 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
11496 Suppress_Initialization pragma for a derived type.
11497 (Is_Variable_Size_Record): New subprogram.
11498 (Build_Offset_To_Top_Functions): New implementation that simplifies the
11499 initial version of this routine and also fixes problems causing
11500 incomplete initialization of the table of interfaces.
11501 (Build_Init_Procedure): Improve the generation of code to initialize the
11502 the tag components of secondary dispatch tables.
11503 (Init_Secondary_Tags): New implementation that simplifies the previous
11504 version of this routine.

11506 object declaration, for diagnostic purposes.
11507 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
11508 diagnose attemps to freeze a subprogram when some untagged type of its
11509 profile is a private type whose full view has not been analyzed yet.
11510 (Freeze_Array_Type): Generate init proc for packed array if either
11511 Initialize or Normalize_Scalars is set.
11512 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
11513 constructing the new profile, copy the null_exclusion indicator for each
11514 parameter, to ensure full conformance of the new body with the spec.

11517 Create wrappers for constructor functions that need it, even when not
11518 marked Requires_Overriding.
11519 (Covers): Handle properly designated types of anonymous access types,
11520 whose non-limited views are themselves incomplete types.
11521 (Add_Entry): Use an entity to store the abstract operation which hides
11523 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.

11530 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
11531 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
11532 (Write_Overloads): Output the abstract operator if present.
11533 (Add_Entry): Before inserting a new entry into the interpretation table
11534 for a node, determine whether the entry will be disabled by an abstract

11551 types declared in the declarative part of a nested package body or in
11552 the proper body of a stub.

11554 of the same dispatch table slot to renamed primitives.
11555 (Make_Select_Specific_Data_Table): Handle private types.

11557 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
11558 output of implicit importation and exportation.
11559 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11560 first formal of the thunk is always associated with the controlling
11561 type. In addition perform the following code cleanup: remove formal
11562 Thunk_Alias which is no longer required, cleanup evaluation of the
11563 the controlling type, and update the documentation.
11564 Replace occurrence of Default_Prim_Op_Count by
11565 Max_Predef_Prims. Addition of compile-time check to verify
11566 that the value of Max_Predef_Prims is correct.
11567 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11568 (Make_DT): Add parameter to indicate when type has been frozen by an
11569 object declaration, for diagnostic purposes.
11570 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11571 construction of statically allocated dispatch tables.
11572 (Make_DT): In case of library-level tagged types export the declaration
11573 of the primary tag. Remove generation of tags (now done by Make_Tags).
11574 Additional modifications to handle non-static generation of dispatch
11575 tables. Take care of building tables for asynchronous interface types
11576 (Make_Tags): New subprogram that generates the entities associated with
11577 the primary and secondary tags of Typ and fills the contents of Access_
11578 Disp_Table. In case of library-level tagged types imports the forward
11579 declaration of the primary tag that will be declared later by Make_DT.
11580 (Expand_Interface_Conversion): In case of access types to interfaces
11581 replace an itype declaration by an explicit type declaration to avoid
11582 problems associated with the scope of such itype in transient blocks.

11585 Ed Schonberg <schonberg@adacore.com>
11586 Javier Miranda <miranda@adacore.com>
11588 * exp_util.ads, exp_util.adb:
11589 This patch replaces a number of occurrences of explicit tests for N_Null
11590 with calls to Known_Null. This improves tracking of null values, since
11591 Known_Null also catches null constants, and variables currently known to
11592 be null, so we get better tracking.
11593 (Ensure_Defined): create an itype reference only in the scope of the
11595 (Side_Effect_Free): A selected component of an access type that
11596 denotes a component with a rep clause must be treated as not
11597 side-effect free, because if it is part of a linked structure its
11598 value may be affected by a renaming.
11599 (Expand_Subtype_From_Expr): For limited objects initialized with build
11600 in place function calls, do nothing; otherwise we prematurely introduce
11601 an N_Reference node in the expression initializing the object, which
11602 breaks the circuitry that detects and adds the additional arguments to
11603 the called function. Bug found working in the new patch for statically
11604 allocated dispatch tables.
11605 (Is_Library_Level_Tagged_Type): New subprogram.
11606 (Remove_Side_Effects): If the expression of an elementary type is an
11607 operator treat as a function call.
11608 (Make_Literal_Range): If the index type of the array is not integer, use
11609 attributes properly to compute the constraint on the resulting aggregate
11612 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11613 class-wide type whose base type is an incomplete private type, leave
11614 class-wide type unfrozen so that freeze nodes can be generated
11615 properly at a later point.
11616 (Freeze_Entity, array case): Handle case of pragma Pack and component
11617 size attributre clause for same array.

11677 source dirs are not known.
11678 (Check_Ada_Name): Allow all identifiers that are not reserved words

12274 traversing over the primitives of the formal and actual types to locate
12275 any abstract subprograms of the actual type that correspond to a
12276 nonabstract subprogram of the formal type's ancestor type(s), and issue
12277 an error if such is found.
12278 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
12279 Instantiate_Package_Body, Instantiate_Subprogram_Body):
12280 Remove bogus guard around calls to Inherit_Context.
12281 (Reset_Entity): If the entity is the selector of a selected component
12282 that denotes a named number, propagate constant-folding to the generic
12283 template only if the named number is global to the generic unit.

12290 parameter to determine whether operation applies to the prefix.
12291 (Complete_Object_Operation): If actual has an access type and
12292 controlling formal is not an in_parameter, reject the actual if it is
12293 an access_to_constant type.
12294 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
12295 type, the candidate operations are found in the scope of declaration of
12296 the type, because the type has no primitive subprograms.
12297 (Analyze_Selected_Component): If prefix is class-wide, and root type is
12298 a private extension, only examine visible components before trying to
12299 analyze as a prefixed call.
12300 Change Entity_List to Type_To_Use, for better readability.

12313 (Missing_Read_Write_Attributes): A stream attribute is missing for the
12314 purpose of enforcing E.2.2(8) only if it is not available at any place.
12315 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
12316 when checking the legality of an extension aggregate in a preelaborable
12317 package. Treat the literal null as a valid default expression in a
12318 component declaration for a type with preelaborable initialization.
12319 A limited interface is a legal progenitor for the designated type of a
12320 remote access to class-wide type.

12333 (Find_Selected_Component, Has_Components): Handle properly non-limited
12334 views that are themselves incomplete types.
12335 Handle interfaces visible through limited-with clauses.
12336 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
12337 subprogram generic actual for which we have generated a renaming.
12338 Warn when the renaming introduces a homonym of
12339 the renamed entity, and the renamed entity is directly visible.

12351 (Resolve): When looping through all possible interpretations of a node,
12352 do not consider those that are hidden by abstract operators.
12353 (Resolve_Actuals): When verifying that an access to class-wide object
12354 is an actual for a controlling formal, ignore anonymous access to
12355 subprograms whose return type is an access to class_wide type.
12356 (Resolve_Slice): If the prefix of the slice is a selected component
12357 whose type depends on discriminants, build its actual subtype before
12358 applying range checks on the bounds of the slice.
12359 (Valid_Conversion): In an instance or inlined body, compare root types,
12360 to prevent anomalies between private and public views.

12382 elabration statements, register the package with the name server
12383 at the beginning, not at the end, of the elaboration statements so
12384 that they can create remote access to subprogram values that designate
12385 remote subprograms from the package.

13559 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13560 class-wide types visible through limited-with clauses.
13561 (Try_Primitive_Operation): When examining all primitive operations of a
13562 tagged type, do not consider subprograms labeled as hidden unless they
13563 belong to a private generic type with a tagged parent.
13564 (Try_Object_Operation): Extensive rewriting, to handle properly various
13565 overloading cases, when several ancestors may have class-wide operations
13566 that are possible candidates, and when the overloaded functions return
13567 array types and have defaulted parameters so that the call may be
13568 interpreted as an indexing.
13569 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13570 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13571 successive actuals before analyzing the call itself.
13572 (Try_Primitive_Operation): A primitive operation is compatible with the
13573 prefix if the prefix has a synchronized type and the type of the formal
13574 is its corresponding record, as can be the case when the primitive
13575 operation is declared outside of the body of the type.
13576 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13577 perform homonym traversal, looking for class-wide operation matches
13578 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13579 access parameters are now restricted to anonymous access types.
13580 (Mark_Allocator): An allocator with a discriminant association parent is
13582 (Try_One_Prefix_Interpretation): If the type of the object is
13583 incomplete, as can be happen when it is a limited view obtained through
13584 a limited_with_clause, the selected component is not part of a prefixed
13586 (Complete_Object_Operation): Diagnose properly an object that is not
13587 aliased when the corresponding controlling formal is an access
13589 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13590 ambiguous calls in prefixed notation, where two primitives differ only
13591 in that the controlling argument of one is an access parameter.
13593 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13594 whether a function that returns an unconstrained type can be inlined.
13595 (Process_Formals): Diagnose properly the illegal use of an incomplete
13596 type in the profile of an access_to_subprogram declaration.
13597 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13598 operations are attached to the corresponding record.
13599 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13600 When processing a primitive of a concurrent type which implements an
13601 interface change the type of all controlling formals to that of the
13602 corresponding record type.
13603 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13604 to determine the tagged type to which a primitive belongs.
13605 (Check_Conventions): Capture condition to ignore a primitive operation
13606 (which is shared between the loop in Check_Conventions and the one in
13607 Check_Convention) in a new local function Skip_Check.
13608 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13609 confusion with Check_Conventions' own Prim_Op local variable.
13610 (Create_Extra_Formals): Test for a tagged result type rather than a
13611 controlling result when determining whether to add a BIP_Alloc_Form
13612 formal and a BIP_Final_List formal to the function.
13613 (Check_Conformance); For parameters that are anonymous access types,
13614 subtype conformance requires that the not null and the constant
13615 indicators must match
13616 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13617 to retrieve the appropriate type when processing a concurrent type
13618 declared within a generic. Minor comment reformatting. Change invocation
13619 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13621 (Analyze_Subprogram_Body): If the return type of a function is an
13622 anonymous access to the limited view of a class-wide type, and the
13623 non-limited view of the type is available, update the type of the
13624 function so that code can be generated.
13625 (Process_Formals): In case of access-subtype itype whose designated
13626 type is also an itype (situation that happens now with access to
13627 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13628 attribute to avoid backend problems.
13629 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13630 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13631 anonymous types' designated types are same before testing
13632 Subtypes_Statically_Match.
13633 (Create_Extra_Formals): Test for a named access parameter that is a
13634 controlling formal as an additional condition for adding an
13635 accessibility level formal. This can occur in the subp type created for
13636 dispatching calls in Expand_Dispatching_Call, and allows calling
13637 Create_Extra_Formals from that procedure rather than special-casing the
13638 extra formals there.
13639 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13640 when the function has a controlling result.
13641 (Check_Returns): Add much more knowledge of the optimization of local
13642 raise statements to gotos, to retain proper warnings in this case.
13643 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13644 nodes when looking for last statement.
13646 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13647 class-wide types visible through limited with clauses.
13648 (Add_One_Interp): If the operands are anonymous access types, the
13649 predefined operator on universal_access is immediately visibles
13650 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13651 other anonymous access types.
13652 (Disambiguate): Take into account CIL convention.
13653 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13655 2007-06-06 Robert Dewar <dewar@adacore.com>
13657 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13658 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13659 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13660 Fix lower bound of tables.
13663 * nlists.adb: Ditto.
13664 (Prev_Node, Next_Node): Change index type to Int so that it properly
13665 covers the range First_Node_Id - 1 up.
13667 2007-06-06 Javier Miranda <miranda@adacore.com>
13668 Ed Schonberg <schonberg@adacore.com>
13669 Bob Duff <duff@adacore.com>
13670 Hristian Kirtchev <kirtchev@adacore.com>
13672 * exp_aggr.ads, exp_aggr.adb:
13673 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13674 in extension aggregates.
13675 (Flatten): Other conditions being met, an aggregate is static if the
13676 low bound given by component associations is different from the low
13677 bound of the base index type.
13678 (Packed_Array_Aggregate_Handled): If the component type is itself a
13679 packed array or record, the front-end must expand into assignments.
13680 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13681 Init_Pr, instead of Ancestor_Is_Expression.
13682 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13683 coextension chain root, either generate a list controller or use the
13684 already existing one.
13685 (Static_Array_Aggregate): New procedure to construct a positional
13686 aggregate that can be handled by the backend, when all bounds and
13687 components are compile-time known constants.
13688 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13689 types covering interface types into assignments.
13690 (Replace_Type): move to Build_Record_Aggr_Code.
13691 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13692 interface type, convert to the definite type of the aggregate itself,
13693 so that needed components are visible.
13694 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13695 components and the context is an extended return statement do not
13696 create a transient block for it, to prevent premature finalization
13697 before the return is executed.
13698 (Gen_Assign): Do not generate a call to deep adjust routine if the
13699 component type is itself an array of controlled (sub)-components
13700 initialized with an inner aggregate.
13701 (Component_Check): New name for Static_Check. This name is now more
13702 appropriate, and documentation is added which was missing.
13703 (Component_Check): Add test for bit aligned component value
13704 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13705 Tagged_Comps, name is more appropriate given added function below.
13706 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
13708 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13709 Javier Miranda <miranda@adacore.com>
13710 Robert Dewar <dewar@adacore.com>
13712 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13713 Terminated: Add unchecked type conversion from System.Address to
13714 System.Tasking.Task_Id when calling the predefined primitive
13716 Disable new Ada 05 accessibility check for JVM.NET targets, which
13717 cannot be implemented in a practical way.
13718 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13719 the sources always references the tag of the actual object. Therefore,
13720 if 'Tag is applied in the sources to class-wide interface objects we
13721 generate code that displaces "this" to reference the base of the object.
13722 (Expand_N_Attribute_Reference, case Size): Return specified size if
13723 known to front end.
13724 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13725 has code that displaces the pointer of the object to manage interface
13726 types. However this code must not be executed when the prefix is a
13727 subprogram. This bug caused the wrong expansion of the internally
13728 generated assignment that fills the dispatch table when the primitive
13729 is a function returning a class-wide interface type.
13730 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13731 Set_Attribute_Name for Name_Unaligned_Valid.
13733 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13734 Gary Dismukes <dismukes@adacore.com>
13736 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13737 If the initialization is the equivalent aggregate of the initialization
13738 procedure of the type, do not remove it.
13739 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13740 initialized to null from having their expression reset to empty and
13741 note this exception in the comment.

13745 Ed Schonberg <schonberg@adacore.com>
13746 Gary Dismukes <dismukes@adacore.com>
13748 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13749 Add "with" and "use" clauses for Sem_Attr.
13750 (Expand_Current_Value): Do not replace occurences of attribute
13751 references where the prefix must be a simple name.
13753 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13754 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13755 Attribute_Requires_Simple_Name_Prefix.
13756 (Name_Modifies_Prefix): Body of new function.
13757 (Requires_Simple_Name_Prefix): Body of new function.
13758 (Resolve_Attribute, case Access): Improve error message for case of
13759 mismatched conventions.
13760 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13762 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13763 constrained subtype for a nominal unconstrained type, use its base type
13764 to check for conformance with the context.
13765 (Resolve_Attribute): Remove test of the access type being associated
13766 with a return statement from condition for performing accessibility
13767 checks on access attributes, since this case is now captured by
13768 Is_Local_Anonymous_Access.
13769 (Analyze_Access_Attribute): Set Address_Taken on entity
13770 (Analyze_Attribute, case Address): Set Address_Taken on entity
13771 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13772 validating an access attribute whose prefix is a current instance.
13773 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13774 applied to dispatching operations, if freezing is required then we set
13775 the attribute Has_Delayed_Freeze in the prefix's entity.
13776 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13777 current scope if access of local subprogram taken
13778 (Analyze_Access_Attribute): Check legality of self-reference even if the
13779 expression comes from source, as when a single component association in
13780 an aggregate has a box association.
13781 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13782 the prefix if it is a protected operation and the attribute is
13783 Unrestricted_Access.
13784 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13785 reference to the base type of the context, to force a constraint check
13786 when the context is an access subtype with an explicit constraint.
13787 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13788 node is rewritten as an interface conversion. leave unanalyzed after
13789 resolution, to ensure that type checking against the context will take

13793 Javier Miranda <miranda@adacore.com>
13794 Robert Dewar <dewar@adacore.com>
13796 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13797 wrapper when the full view of the controlling type of an inherited
13798 function that dispatches on result implements interfaces.
13799 (Expand_N_Object_Declaration): In cases where the type of the
13800 declaration is anonymous access, create finalization list for it.
13801 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13802 if the object has no explicit initialization, to match description of
13803 functionality of pragam Persistent_BSS.
13804 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13805 new function to build static aggregates, to replace initialization call
13806 when static initialization is desired.
13807 (Freeze_Type): Generate a list controller for an access type whenever
13808 its designated type has controlled anonymous access discriminants.
13809 (Build_Equivalent_Aggregate): New procedure to compute a static
13810 aggregate to be used as default initialization for composite types,
13811 instead of a generating a call to the initialization procedure for the
13813 (Build_Initialization_Call): When available, replace a call to the
13814 initialization procedure with a copy of the equivalent static aggregate
13816 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13817 declarations for objects of a class-wide interface type, rather than
13818 just identifiers, to prevent visibility problems.
13819 (Expand_N_Object_Declaration): When expanding the declaration for an
13820 object of a class-wide interface type, preserve the homonym chain of
13821 the original entity before exchanging it with that of the generated
13822 renaming declaration.
13823 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13824 active, because there is no way to handle the exception.
13825 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13826 to do a minimum decoration of the Access_Disp_Table list.
13827 (Expand_Record_Controller): Avoid the addition of the controller between
13828 the component containing the tag of a secondary dispatch table and its
13829 adjacent component that stores the offset to the base of the object.
13830 This latter component is only generated when the parent type has
13831 discriminants ---documented in Add_Interface_Tag_Components).
13832 (Apply_Array_Size_Check): Removed, no longer needed.
13833 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13834 components, create a Master_Entity for it only if it contains tasks.
13835 (Build_Init_Procedure): Suppress the tag assignment compiling under
13837 (Freeze_Record_Type): Remove code associated with creation of dispatch
13839 (Init_Secondary_Tags): Update type of actuals when generating calls to
13840 Ada.Tags.Set_Offset_To_Top
13841 (Stream_Operation_OK): Disable use of streams compiling under no
13843 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13844 if Has_Init_Expression set.
13845 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13846 Register_Primitive, which provides the same functionality.
13847 (Requires_Init_Proc): Return false in case of interface types.
13848 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13850 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13851 is always associated with a predefined primitive because the internal
13852 entities associated with interface types are not predefined primitives.
13853 Therefore, the call to Is_Internal is replaced by a call to the
13854 function Is_Predefined_Dispatching_Operation.
13855 (Make_Eq_If): When generating the list of comparisons for the
13856 components of a given variant, omit the controller component that is
13857 present if the variant has controlled components.
13859 2007-06-06 Javier Miranda <miranda@adacore.com>
13860 Hristian Kirtchev <kirtchev@adacore.com>
13861 Bob Duff <duff@adacore.com>
13863 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13864 handle the creation of finalization lists and calls for nested
13865 coextensions when the root of the chains is part of a return statement.
13866 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13868 (Expand_Record_Equality): Skip components that are interface types.
13869 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13870 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13871 with Rewrite_Coextension. Change the condition for detecting coextension
13873 (Is_Local_Access_Discriminant): Removed.
13874 (Rewrite_Coextension): New routine which rewrites a static coextension
13875 as a temporary and uses its unrestricted access in the construction of
13877 (Complete_Coextension_Finalization): New routine. Generate finalization
13878 attachment calls to all delayed coextensions.
13879 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13880 the allocator is not a coextension itself and has delayed coextensions.
13881 If the current allocator is controlled, but also a coextension, delay
13882 the generation of the finalization attachment call.
13883 Rename local variable "Node" to "Nod" in order to avoid confusion with
13885 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13886 limited types that are not inherently limited. Such an allocator is
13887 illegal, but is generated by the expander for a return statement, to
13888 copy the result onto the secondary stack. This is the only case where a
13889 limited object can be copied. Generate code to displace the pointer
13890 to the object if the qualified expression is a class-wide interface
13891 object. Such displacement was missing and hence the copy of the object
13893 (Apply_Accessibility_Check): Handle allocated objects initialized in
13895 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13896 and Expand_Allocator_Expression. Allocating class-wide interface objects
13897 this routine displaces the pointer to the allocated object to reference
13898 the component referencing the corresponding secondary dispatch table.
13899 Expand_Allocator_Expression): Add missing support to allocate class-wide
13900 interface objects initialized with a qualified expression.
13901 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13902 function result type, and use the finalization list associated with the
13903 function scope in that case (such an anonymous type should not be
13904 treated like an access parameter's type).
13906 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13907 Gary Dismukes <dismukes@adacore.com>
13908 Javier Miranda <miranda@adacore.com>
13910 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13911 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13912 required exception handler.
13913 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13914 properly the case of a function whose return type is a limited
13915 class-wide interface type. Modify the code of the accessibility
13916 check to handle class-wide interface objects. In this case we need to
13917 displace "this" to reference the primary dispatch table to get access
13918 to the TSD of the object (to evaluate its accessibility level).
13919 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13920 rather than a controlling result as one of the conditions for
13921 generating tests of the implicit BIP_Alloc_Form formal. The
13922 initialization assignment is also handled according to whether the
13923 result is tagged instead of controlling.
13924 In the case where the init assignment is inserted in the "then" part of
13925 the allocation conditional, rewrite the target to be a dereference of
13926 the implicit BIP_Object_Access formal.
13927 If the returned value is unconstrained and created on the secondary
13928 stack, mark the enclosing block and function so that the secondary
13929 stack is not reclaimed on return.
13930 Treat returns from functions with controlling results similarly to
13931 returns from functions with unconstrained result subtypes.
13932 If the object returned is unconstrained, and an allocator must be
13933 created for it, analyze the allocator once the block for the extended
13934 return is installed, to ensure that finalizable components
13935 of the expression use the proper finalization list. Guard the call to
13936 Move_Final_List with a check that there is something to finalize.
13937 (Make_Tag_Ctrl_Assignment): Use "old" handling
13938 of controlled type assignment for virtual machines, since new code uses
13939 unsupported features (such as direct access to bytes in memory).
13941 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13942 Ed Schonberg <schonberg@adacore.com>
13944 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13945 accessibility actual, check for the case of an aliased object that has
13946 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13947 we fall into processing for the attribute rather than the name of the
13949 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13950 formal has its address taken in the body, create a temporary to capture
13951 value. If the return type is a limited interface, do not treat the
13952 return value as Controlled.
13953 (Is_In_Place_Function): If the return type is a limited interface,
13954 treat as returning in place. The actual returned object may not always
13955 be limited, but the caller has to assume that it is returned in place.
13956 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13957 context of an allocator, use the correct finalization chain (that is,
13958 the chain belonging to the access type, rather than the chain belonging
13959 to the current scope).
13960 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13961 result type rather than a controlling result as a precondition for
13962 adding an allocation form actual to a build-in-place call.
13963 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13964 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13965 primitive in the dispatch tables. This work is now done by Make_DT when
13966 the type is frozen.
13967 (Register_Predefined_DT_Entry): Removed.
13968 (Add_Return): If end label is not present, use sloc of last statement
13969 for generated return statement in procedure, for better gdb behavior
13971 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13972 object address nodes to ensure proper processing by routines like
13974 (Expand_Call): Fix generation of validity check for parameter
13975 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13976 the allocation form parameter if the result subtype is constrained,
13977 except when the function has a controlling result.
13978 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13979 rather than Is_Controlled and Has_Controlled_Component, since we want to
13980 include class-wide result types in this treatment. Also test for a
13981 controlling result, since that also requires passing a finalization
13983 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13984 even when the result subtype is constrained, to handle calls involving
13985 controlling results.
13986 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13987 is now called even when the result subtype is constrained, to handle
13988 calls involving controlling results.
13989 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13990 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13991 now performs the test).
13992 (Make_Build_In_Place_Call_In_Object_Declaration):
13993 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13994 constrained, to handle calls involving controlling results.
13995 (Add_Return): Accomodate rewritten pattern from local raise to goto
13996 transformation, so that we still recognize an transfer statement
13997 and do the right thing here in that case.
13998 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13999 and end of subprogram code.
14000 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
14001 support for primitives that are functions (without formals) with a
14002 controlling result.
14003 (Inherited_From_Formal): If the actual subtype has not generic parent
14004 type, it is not an actual for a formal derived type, and there is no
14005 operation to inherit from the formal.

14013 exception handler for Deep_Adjust or Deep_Finalize.
14014 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
14015 Raise_From_Controlled_Operation is available, use a call to that
14016 subprogram instead of a plain "raise Program_Error" node to raise
14017 Program_Error if an exception is propagated from an Adjust or Finalize
14019 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
14020 appears in the optional statement list of a triggering alternative, the
14021 scope actions can be inserted directly there, and not in the list that
14022 includes the asynchronous select itself.
14024 2007-06-06 Ed Schonberg <schonberg@adacore.com>
14025 Robert Dewar <dewar@adacore.com>

14052 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
14053 functionality when the backend is generating code.
14054 Otherwise any serious error
14055 reported by the backend calling the frontend routine Error_Msg
14056 changes the Compilation_Mode to Check_Semantics, disables the
14057 functionality of this routine and causes the generation of
14058 spureous additional errors.
14060 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
14061 debugging information now generated by the compiler for fat-pointer
14063 Document the contents of DW_AT_producer in the GNAT Vendor extensions to

14074 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
14075 stream attributes of the designated type of an RACW, as they are not
14076 dispatching primitive operations.

14096 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
14097 deallocation of class-wide interface objects.
14098 (Expand_Dispatching_Constructor_Call): Take into account that if the
14099 result of the dispatching constructor is an interface type, the
14100 function returns a class-wide interface type; otherwise the returned
14101 object would be actual. The frontend previously accepted returning
14102 interface types because Expand_Interface_Actuals silently performed
14103 the management of the returned type "as if" it were a class-wide
14105 (Expand_Dispatching_Constructor_Call): Replace call to
14106 Make_DT_Access_Action by direct call to Make_Function_Call.

14111 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
14112 compute masking constant, since we now set Esize properly to the
14114 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
14115 to match the alignment.

14126 the size being incorrect, check RM_Size, not Esize.
14127 (Freeze_Record_Type): Check for bad discriminated record convention
14128 (In_Exp_Body): Return true if the body is generated for a subprogram
14129 renaming, either an attribute renaming or a renaming as body.
14130 (Check_Itype): If the designated type of an anonymous access component
14131 is a non-protected subprogram type, indicate that it is frozen, to
14132 prevent out-of-scope freeze node at some subsequent call.
14133 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
14134 only if the subprogram is neither imported nor exported, as well as the

14139 Robert Dewar <dewar@adacore.com>
14140 Gary Dismukes <dismukes@adacore.com>
14142 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
14143 default initialization on an imported object, when there is no
14144 initialization call generated for it.

14164 to apply Import to an object renaming declaration.
14166 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
14167 from a C++ class should be declared as limited and that it will be
14168 considererd limited.
14169 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
14170 should be declared as limited and that it will be considererd limited.

14195 object of a limited type can be initialized with a call to a function
14196 that returns in place. If the limited type has unknown discriminants,
14197 and the underlying type is a constrained composite type, build an actual
14198 subtype from the function call, as is done for private types.
14199 (Side_Effect_Free): An expression that is the renaming of an object or
14200 whose prefix is the renaming of a object, is not side-effect free
14201 because it may be assigned through the renaming and its value must be
14202 captured in a temporary.
14203 (Has_Controlled_Coextensions): New routine.
14204 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
14205 as is done for other limited types.

14255 Add new warning for renaming of function return objects
14257 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
14258 (Tree_Read): Use size of object instead of type'object_size, since the
14259 latter is incorrect for packed array types.

14262 * opt.ads: Add new warning for renaming of function return objects
14263 (Generating_Code): New boolean variable used to indicate that the

14277 Standard can be renamed.
14278 (Analyze_Object_Renaming): Add new warning for renaming of function
14280 Also reject attempt to rename function return object in Ada 83 mode.
14281 (Attribute_Renaming): In case of tagged types, add the body of the
14282 generated function to the freezing actions of the type.
14283 (Find_Type): A protected type is visible right after the reserved word
14284 "is" is encountered in its type declaration. Set the entity and type

14312 (Deallocate, Dereference): Send error messages to the proper stream
14313 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
14314 documented. Previous code would send it to the current output file
14315 defined in GNAT.IO, which might not be stdout
14316 (Is_Valid): Adjust comment to mention that a positive reply means that
14317 Header_Of may be used to retrieve the allocation header associated with

14337 Correct error message when invocation of the linker fails
14338 Add explicit size clause for the C imported variables
14339 Object_List_File_Supported and Using_GNU_Linker to emphasize that
14340 we expect char size.
14341 Read target parameters earlier, since this is needed to set
14342 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
14345 2007-06-06 Vincent Celier <celier@adacore.com>
14348 Add 3 spaces before the default project directory when displaying
14349 the project search path.

14728 association, and the corresponding record component has a default
14729 expression, always copy the default expression, even when the

14916 Do_Division_Check flag explicitly.
14917 (Resolve_Actuals): If the actual is of a synchronized type, and the
14918 formal is of the corresponding record type, this is a call to a
14919 primitive operation of the type, that is declared outside of the type;
14920 the actual must be unchecked-converted to the type of the actual

14955 both entities. This is required to statically build the dispatch table.
14956 (Declare_Inherited_Private_Subprograms): Rewriten to avoid the need
14957 of calling Set_All_DT_Position to re-evaluate the position of the
14958 entries in the dispatch table. Such reevaluation is not desired if

15824 scope treatment. Update comments to describe this exception.
15825 (Resolve_Equality_Op): In case of dispatching call check violation of

15827 (Resolve_Call): If the call returns an array, the context imposes the
15828 component type of the array, and the function has one non-defaulted
15829 parameter, rewrite the call as the indexing of a call with a single
15830 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15832 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15833 the master of the created object is the innermost enclosing statement.
15834 (Remove_Conversions): For a binary operator, check if type of second
15835 formal is numeric, to check if an abstract interpretation is present
15836 in the case of exponentiation as well.

15934 overriding" is subtly different from "is abstract" (see AI-228).
15935 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
15936 Is_Abstract_Type. Make sure these are called only when appropriate.

15970 (Expand_Inlined_Call): If the subprogram is a null procedure, or a
15971 stubbed procedure with a null body, replace the call with a null

15998 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
15999 "abstract subprograms must be visible" message, whether or not the type

16027 Remove no longer used entities.
16029 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no

16063 to handle properly the anonymous access case.
16065 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type

16069 "X'Unrestricted_Access = Y'Access" and so forth to match.

16077 attempt to derive from a synchronized tagged type.

16082 that use (a subtype of) the class-wide type of the enclosing type.
16083 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
16084 Derived_Type for Prev formal on call to
16085 Check_Anonymous_Access_Components rather than Empty.
16086 (Make_Incomplete_Type_Declaration): Add test for case where the type has
16087 a record extension in deciding whether to create a class-wide type,

16168 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
16169 when -gnatg is not specified.
16170 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because

16221 parameter of the containing subprogram.
16222 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
16223 under No_Dispatching_Calls restriction. During the semantic analysis

16242 initialize most the TSD components by means of an aggregate.
16243 Modify the declaration of the object containing the TSD
16244 because we now expand code that has a higher level of abstraction.
16245 The TSD has a discriminant containing the Inheritance Depth Level,
16246 value that is used in the membership test but also to fix the size
16247 of the table of ancestors.
16248 (Expand_Interface_Conversion): Insert function body at the closest place
16249 to the conversion expression, to prevent access-before-elaboration
16250 errors in the backend.

16273 Get_Prim_Op_Address Get_RC_Offset, Get_Remotely_Callable, Inherit_DT,
16274 Set_Access_Level, Set_Expanded_Name, Set_Predefined_Prim_Op_Address,
16275 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
16276 (Expand_Dispatching_Call): Replace generation of call to the run-time
16277 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
16278 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
16280 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
16281 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
16282 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
16283 Build_Set_Prim_Op_Address.
16284 (Get_Remotely_Callable): Subprogram removed.
16285 (Init_Predefined_Interface_Primitives): Replace generation of call to
16286 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
16289 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
16290 First (Parameter_Associations ()) with the call to First_Actual that
16291 returns an actual parameter expression for both named and positional
16294 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
16295 check violation of restriction No_Dispatching_Calls.
16296 (Check_Controlling_Type): A formal of a tagged incomplete type is a
16297 controlling argument.

16300 First/Next_Component_Or_Discriminant
16301 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
16302 (Find_Implemented_Interface): Removed. All the calls to this subprogram
16303 specify Any_Limited_Interface, and this functionality is already
16304 provided by the function Has_Abstract_Interfaces.
16305 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
16306 support concurrent types implementing interfaces.
16307 (Find_Implemented_Interface): Removed. All the calls to this subprogram
16308 specify kind Any_Limited_Interface, and this functionality is already
16309 provided by the function Has_Abstract_Interfaces.
16310 (Remove_Side_Effects): replace Controlled_Type by
16311 CW_Or_Controlled_Type whenever the issue is related to
16312 using or not the secondary stack.
16314 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
16315 P_Interface_Type_Definition to fulfill the new interface (the formal
16316 Is_Synchronized is no longer required).
16318 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
16319 Update dependencies.
16321 * exp_atag.ads, exp_atag.adb: New file

16325 Cyrille Comar <comar@adacore.com>
16327 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
16328 anonymous, use finalization list of enclosing dynamic scope.
16329 (Expand_N_Package_Declaration): For a library package declaration
16330 without a corresponding body, generate RACW subprogram bodies in the
16331 spec (just as we do for the task activation call).
16332 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
16333 Is_Abstract_Type. Make sure these are called only when appropriate.
16334 Remove all code for DSP option
16335 (CW_Or_Controlled_Type): new subprogram.

16339 Gary Dismukes <dismukes@adacore.com>
16341 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
16342 parameter. If it is set to true, return a result capped according to
16343 the global upper bound for the index of an entry family.
16344 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
16345 (Build_Find_Body_Index): Adjust for above change.
16346 (Entry_Index_Expression): Likewise.
16347 (Is_Potentially_Large_Family): New function extracted from...
16348 (Collect_Entry_Families): ...here. Call it to detect whether the family
16349 is potentially large.
16350 (Build_Entry_Count_Expression): If the family is potentially large, call
16351 Family_Size with 'Cap' set to true.
16352 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
16353 a protected version of an operation declared in the private part of
16354 a protected object, because they may be invoked through a callback.
16355 (Set_Privals): If the type of a private component is an anonymous access
16356 type, do not create a new itype for each protected body.
16357 If the body of a protected operation creates
16358 controlled types (including allocators for class-widetypes), the
16359 body of the corresponding protected subprogram must include a
16361 (Build_Activation_Chain_Entity): Build the chain entity for extended
16363 (Type_Conformant_Parameters): Use common predicate Conforming_Types
16364 to determine whether operation overrides an inherited primitive.

16366 for a possible overriding candidate.
16367 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
16368 hold an actual parameter value since its initialization is separated
16369 from the the declaration. Prevents errors on null-excluding access
16372 2007-04-06 Thomas Quinot <quinot@adacore.com>
16373 Pablo Oliveira <oliveira@adacore.com>
16375 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
16376 Do an Unchecked_Conversion to handle the passage from the Underlying
16377 Type to the Base Type when calling Build_To_Any_Call and
16378 Build_From_Any_Call.
16379 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
16380 E_Constant, depending upon Variable formal.
16381 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
16382 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
16383 parameter that requires an extra constrained parameter, declare
16384 temporary for actual as a variable, not a constant.
16385 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
16386 the unit being compiled is the one that contains the stub type.
16387 Change primitive operation name for the RACW associated with a RAS
16388 from Call to _Call so it cannot clash with any legal identifier.
16389 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
16391 (Append_RACW_Bodies): New subprogram.
16392 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
16393 Add_Receiving_Stubs_To_Declarations functions.
16394 When expanding a package body, this list correspond to the
16395 statements in the HSS at the end of the pacakge.
16396 When expanding a package spec, this list correspond to the
16398 (Add_Receiving_Stubs_To_Declarations): Append the function
16399 registering the receiving stubs at the end of the 'Stmts' list.
16400 (RCI_Package_Locator): Pass the new Version generic formal when
16401 instantiating a RCI_Locator package.
16402 (Build_From_Any_Function): To compute the High bound for an
16403 unconstrained array actual, we add the Low bound with the length.
16404 Thus we must convert the low bound and the length to an appropriate
16405 type before doing the sum.
16406 (Build_Subprogram_Receiving_Stubs, PolyORB):
16407 * Retrieve the extra formals parameters at the
16408 end of the parameter stream.
16409 * Use Move_Any_Value to write back out parameters
16410 after executing the request as it is more efficient
16411 than Copy_Any_Value.
16412 * Build the any containing Extra Formals with the
16413 appropriate typecode.
16414 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
16415 empty Component_List.
16416 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
16417 the tree the declaration for an object that serves as actual parameter
16418 in server-side stubs.
16419 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
16420 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
16421 Use Build_Actual_Object_Declaration to prepare the actuals.

16428 function with the first not implicit parent type.
16429 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
16430 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
16431 typecode from the Etype. Therefore we retrieve the correct typecode
16432 with a call to Get_Any_Type.
16433 (Copy_Specification): Do controlling formal type substitution based on
16434 Is_Controlling_Formal flag, instead of caller-provided object type.
16435 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
16436 a RACW primitive operation, we might get a subprogram declaration for an
16437 ancestor of the RACW designated type (not for the designated type
16438 itself), in the case where this operation is inherited. In this case we
16439 have no easy means of determining the original tagged type for which
16440 the primitive was declared, so instead we now rely on
16441 Copy_Specification to use the Is_Controlling_Formal flag to determine
16442 which formals require type substitution.

16448 GNAT.Current_Exception are not allowed if pragma Restrictions
16449 (No_Exception_Propagation) is set and in any case make the associated
16450 handler unsuitable as a target for a local raise statement.
16451 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
16452 run-time subprogram CW_Membership by call to Build_CW_Membership.
16453 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
16454 by a function call, a temporary must be created before expanding the
16455 Constructor_Call itself, to prevent out-of-order elaboration in the
16456 back-end when stack checking is enabled..
16458 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16460 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
16461 result are the bounds of the left operand, not the right.
16463 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16466 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use
16467 discriminant defaults.

16472 Bob Duff <duff@adacore.com>
16474 * sem_aggr.adb (Resolve_Record_Aggregate): In semantics-only mode treat
16475 an association with a box as providing a value even though the

16478 box corresponds to a component of the type.
16479 (Resolve_Record_Aggregate): Split Is_Abstract flag into
16480 Is_Abstract_Subprogram and Is_Abstract_Type.

16495 offering facilities for all the Vector/View conversion routines
16496 implemented by this unit.

16583 * mingw32.h (S2WSU): New macro to convert from a string to a
16584 wide-string using the UTF-8 encoding. The S2WS macro supports now only
16585 standard 8bits encoding.
16586 (WS2SU): As above but converting from wide-sring to string.
16587 This is needed as it is necessary to have access to both versions in the
16588 runtime for the form parameter encoding support.
16589 This set of patch add support for the encoding form parameter.
16590 (S2WS): Improve implementation to handle cases where the filename is not
16591 UTF-8 encoded. In this case we default to using the current code page
16592 for the conversion.
16594 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
16595 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

16604 corresponding encoding value into AFCB structure.
16605 (Reset): Pass the encoding value to freopen.

16639 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16640 __gnat_adjust_context_for_raise.
16641 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16642 implementation of floating point operations as native x86 targets.
16643 So the FPU should be initialized in the same way using finit. Fix
16644 floating point operations accuracy issues.
16645 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
16646 member in struct sigaction, so as to avoid warning for incompatible

16662 Javier Miranda <miranda@adacore.com>
16664 * lib-xref.ads, lib-xref.adb:
16665 Modify the loop that collects type references, to include interface
16666 types that the type implements. List each of these interfaces when
16667 building the entry for the type.
16668 (Generate_Definition): Initialize component Def and Typ of new entry
16669 in table Xrefs, to avoid to have these components unitialized.

16713 2007-04-06 Robert Dewar <dewar@adacore.com>
16715 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16716 it no longer destroys the contents of Name_Buffer or Name_Len and
16717 non-standard and invalid names are handled better.
16718 (Get_Decoded_Name_String): Improve performance by using
16719 Name_Has_No_Encodings flag in the name table.

16724 Javier Miranda <miranda@adacore.com>
16725 Bob Duff <duff@adacore.com>
16727 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16728 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16729 there is no need to generate always a record_definition_node in case
16730 of synchronized interface types.
16731 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16732 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16733 illegal in Ada 95, in cases where it is legal. Change the warnings to
16734 errors in other cases. Don't give the error unless the "not null"
16735 parses properly. Correct the source position at which the error occurs.
16736 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16737 P_Null_Exclusion, to suppress "not null" warnings.

16789 Entry for pragma Unreferenced_Objects
16791 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
16792 switches, without repetition of "eD". Make sure that last character of
16793 -gnatep= switch is not taken as -gnat switch character.
16794 Complete rewrite of circuit for handling saving compilation options

16813 the default project path, initially done during elaboration of the
16815 If the prefix returned by Sdefault is null, get the prefix from a call
16816 to Executable_Prefix_Path.
16817 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16820 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16821 canonical directory name to open the directory from which files are
16823 (Record_Other_Sources): Idem.
16824 (Locate_Directory): Add the possibility to create automatically missing
16825 directories when Setup_Projects is True.
16826 Call Locate_Directory so that the directory will be created when

16828 library source copy dir and exec dir.
16830 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16833 2007-04-06 Robert Dewar <dewar@adacore.com>

16868 full word is no longer compared twice.
16870 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16872 * sem_ch10.adb (Install_Limited_Context_Clauses.
16873 Expand_Limited_With_Clause): Use a new copy of selector name in the
16874 call to Make_With_Clause. This fixes the tree structure for ASIS
16875 purposes. Nothing is changed in the compiler behaviour.
16876 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16877 a package renaming.
16878 (Install_Limited_With_Clauses): Do not install non-limited view when it
16879 is still incomplete.
16881 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16882 Gary Dismukes <dismukes@adacore.com>
16884 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16885 when capturing size information, instead of base type, which for a
16886 formal array type will be the unconstrained type.
16887 (Analyze_Formal_Object_Declaration): Add check for illegal default
16888 expressions for a formal in object of a limited type.
16889 (Instantiate_Object): Ditto.
16890 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16891 because they were defaulted in the formal package and no check applies
16893 (Check_Formal_Package_Instance): Extend conformance check to other
16894 discrete types beyond Integer.
16895 (Process_Default): Copy directly the unmatched formal. A generic copy
16896 has already been performed in Analyze_Formal_Package.
16897 (Analyze_Associations): If a formal subprogram has no match, check for
16898 partial parametrization before looking for a default, to prevent
16900 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16901 not set the instantiation environment before analyzing the actuals.
16902 Fixes regression on 8515-003 with implementation of AI-133.
16903 Set_Instance_Env checks whether the generic unit is a predefined
16904 unit, in which case the instance must be analyzed with the latest Ada
16905 mode. This setting must take place after analysis of the actuals,
16906 because the actuals must be analyzed and frozen in the Ada mode extant
16907 outside of the current instantiation.
16908 (Save_Env, Restore_Env): Preserve and restore the configuration
16909 parameters so that predefined units can be compiled in the proper Ada
16911 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16912 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16913 and Is_Abstract_Type.
16914 (Analyze_Formal_Package): For better error recovery, Add exception
16915 handler to catch Instantion_Error, which can be raised in
16916 Analyze_Associations
16918 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16919 Bob Duff <duff@adacore.com>
16920 Gary Dismukes <dismukes@adacore.com>
16922 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16923 prefix type is a discriminated subtype of the type of the formal.
16924 (Analyze_Allocator): Collect all coextensions regardless of the context.
16925 Whether they can be allocated statically is determined in exp_ch4.
16926 (Analyze_Selected_Component): If the prefix is a limited view and the
16927 non-limited view is available, use the non-limited one.
16928 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16929 therefore illegal), suggest a qualified expression rather than a type
16930 conversion, because a type conversion would be illegal in this context.
16931 (Anayze_Allocator): Trace recursively all nested allocators so that all
16932 coextensions are on the corresponding list for the root. Do no mark
16933 coextensions if the root allocator is within a declaration for a stack-
16934 allocated object, because the access discriminants will be allocated on
16936 (Analyze_Call): Remove restriction on calls to limited functions for the
16937 cases of generic actuals for formal objects, defaults for formal objects
16938 and defaults for record components.
16939 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16940 element list. Their expansion is delayed until the enclosing allocator
16941 is processed and its finalization list constructed.
16942 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16943 for an operation with the given name among the primitive operations of
16944 the corresponding record type.
16945 (Analyze_Selected_Component): If the prefix is a task type that
16946 implements an interface, and there is no entry with the given name,
16947 check whether there is another primitive operation (e.g. a function)
16949 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16950 properly the indexing of a function call written in prefix form, where
16951 the function returns an array type, and all parameters of the function
16952 except the first have defaults.
16953 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16954 the original operands, rather than relocating them, for efficiency and
16955 to work properly when an operand is overloaded.
16956 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16957 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16958 (Analyze_Selected_Component): If the prefix is a private extension, only
16959 scan the visible components, not those of the full view.
16960 (Try_Primitive_Operation): If the operation is a procedure, collect all
16961 possible interpretations, as for a function, because in the presence of
16962 classwide parameters several primitive operations of the type can match
16963 the given arguments.
16965 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16966 Robert Dewar <dewar@adacore.com>
16968 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16969 tag-indeterminate call to an abstract function, when the left-hand side
16971 (Analyze_Loop_Statement): Improve detection of infinite loops
16973 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16974 Thomas Quinot <quinot@adacore.com>
16976 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16977 out of Analyze_Package_Declaration, because processing must be applied
16978 to package bodies as well, for deferred constants completed by pragmas.
16979 (Analyze_Package_Declaration): When the package declaration being
16980 analyzed does not require an explicit body, call Check_Completion.
16981 (May_Need_Implicit_Body): An implicit body is required when a package
16982 spec contains the declaration of a remote access-to-classwide type.
16983 (Analyze_Package_Body): If the package contains RACWs, append the
16984 pending subprogram bodies generated by exp_dist at the end of the body.
16985 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16986 Is_Abstract_Subprogram and Is_Abstract_Type.
16987 (Preserve_Full_Attributes): The full entity list is not an attribute
16988 that must be preserved from full to partial view.
16990 * sem_dist.adb (Add_RAS_Dereference_TSS):
16991 Change primitive name to _Call so it cannot clash with any legal
16992 identifier, and be special-cased in Check_Completion.
16993 Mark the full view of the designated type for the RACW associated with
16994 a RAS as Comes_From_Source to get proper view switching when installing
16995 private declarations.
16996 Provite a placeholder nested package body along with the nested spec
16997 to have a place for Append_RACW_Bodies to generate the calling stubs
16998 and stream attributes.
17000 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17001 Robert Dewar <dewar@adacore.com>
17003 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
17004 that is a limited view, check the non-limited view if available.
17005 (Undefined): Refine error message for missing with of Text_IO
17006 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
17007 to distinguish real missing with cases.
17008 Fix format of all missing with messages
17009 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
17010 renaming as body when renamed entity is abstract.
17012 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17013 Javier Miranda <miranda@adacore.com>
17015 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
17016 predicate recursive, to handle complex expressions on literals whose
17017 spurious ambiguity comes from the abstract interpretation of some
17019 (Interface_Present_In_Ancestor): Add support to concurrent record
17021 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
17022 Is_Abstract_Subprogram and Is_Abstract_Type.
17024 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17025 Javier Miranda <miranda@adacore.com>
17027 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
17028 dereference of a local object R created as a reference to another
17029 object O, use the access level of O.
17030 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
17031 rather than local Same_Formal_Type, to check whether protected operation
17032 overrides an inherited one.
17033 (Same_Formal_Type): New predicate, used when matching signatures of
17034 overriding synchronized operations, to handle the case when a formal
17035 has a type that is a generic actual.
17036 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
17037 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
17038 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
17039 syntactic ambiguities involving indexing of function calls that return
17041 (Abstract_Interface_List): New subprogram that returns the list of
17042 abstract interfaces associated with a concurrent type or a
17043 concurrent record type.
17044 (Interface_Present_In_Parent): New subprogram used to check if a
17045 given type or some of its parents implement a given interface.
17046 (Collect_Abstract_Interfaces): Add support for concurrent types
17047 with interface types.
17048 (Has_Abstract_Interfaces): Add support for concurrent types with
17050 (Is_Parent): New subprogram that determines whether E1 is a parent
17051 of E2. For a concurrent type its parent is the first element of its
17052 list of interface types; for other types this function provides the
17053 same result than Is_Ancestor.
17054 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
17055 (Collect_Synchronized_Interfaces): Removed because the subprogram
17056 Collect_Abstract_Interfaces provides this functionality.
17057 (Collect_Abstract_Interfaces): Minor update to give support to
17058 concurrent types and thus avoid undesired code duplication.
17059 (Get_Subprogram_Entity): Handle entry calls.
17060 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
17062 (Enter_Name): Do not give -gnatwh hiding warning for record component
17063 entities, they never result in hiding.

17066 Robert Dewar <dewar@adacore.com>
17068 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,
17069 to chain nested components that are allocators for access discriminants
17070 of the enclosing object.
17071 Add N_Push and N_Pop nodes
17072 New field Exception_Label added
17073 (Local_Raise_Statements): New field in N_Exception_Handler_Node
17074 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node
17075 (Is_Coextension): New flag for allocators, to mark allocators that
17076 correspond to access discriminants of dynamically allocated objects.
17077 (N_Block_Statement): Document the fact that the corresponding entity
17078 can be an E_Return_Statement.
17079 (Is_Coextension): New flag for allocators.
17080 Remove all code for DSP option
17082 * sprint.ads, sprint.adb: Display basic information for class_wide
17083 subtypes. Add handling of N_Push and N_Pop nodes
17085 2007-04-06 Arnaud Charlet <charlet@adacore.com>
17087 * s-tpobop.adb (Exceptional_Complete_Entry_Body): Undefer abortion
17088 before propagating exception.
17090 2007-04-06 Olivier Hainque <hainque@adacore.com>
17092 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
17093 an address always within the call instruction from a return address.
17095 2007-04-06 Olivier Hainque <hainque@adacore.com>
17096 Eric Botcazou <botcazou@adacore.com>
17098 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
17099 expression with a COMPOUND_EXPR including the call instead of emitting
17100 the call directly here.
17101 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
17102 high bound is constant and the slice is empty. Tidy.
17103 (tree_transform, case N_Op_Not): Handle properly the case where the
17104 operation applies to a private type whose full view is a modular type.
17105 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
17106 Address_Clause, use the associated Expression as the GNAT tree
17107 representing the choice value to ensure the corresponding GCC tree is
17108 of the proper kind.
17109 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
17110 instead of just the operands, as the base GCC stabilize_reference does.
17111 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
17112 requested; otherwise fail.
17113 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
17115 2007-04-06 Thomas Quinot <quinot@adacore.com>
17117 * uintp.ads, uintp.adb (UI_Div_Rem): New subprogram, extending previous
17118 implementation of UI_Div.
17119 (UI_Div): Reimplement as a call to UI_Div_Rem.
17120 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
17121 remainder, avoiding the cost of a multiplication and a subtraction.
17122 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
17123 provides both quotient and remainder in a single computation.
17124 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
17125 functions for uint.
17126 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
17127 is undefined if the given n is not inversible.
17129 2007-04-06 Olivier Hainque <hainque@adacore.com>

17393 anonymous access types.
17394 (Valid_Conversion): For a conversion to a numeric type occurring in an
17395 instance or inlined body, no need to check that the operand type is

18101 the parent part is a build-in-place function call, generate assignments.
18102 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
18103 are build-in-place function calls.
18104 (Replace_Self_Reference): New subsidiary of
18105 Make_OK_Assignment_Statement, to replace an access attribute that is a
18106 self-reference into an access to the appropriate component of the
18107 target object. Generalizes previous mechanism to handle self-references
18108 nested at any level.
18109 (Is_Self_Referential_Init): Remove, not needed.
18110 (Is_Self_Referential_Init): New predicate to simplify handling of self
18111 referential components in record aggregates.
18112 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
18113 check for presence of entity before checking for self-reference.
18114 (Has_Default_Init_Comps): Return True if a component association is a
18115 self-reference to the enclosing type, which can only come from a
18116 default initialization.
18117 (Make_OK_Assignment_Statement): If the expression is of the form
18118 Typ'Acc, where Acc is an access attribute, the expression comes from a
18119 default initialized self-referential component.
18120 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
18121 that has been derived from several abstract interfaces we must also
18122 initialize the tags of the secondary dispatch tables.

18126 Javier Miranda <miranda@adacore.com>
18127 Robert Dewar <dewar@adacore.com>
18130 (Expand_Access_To_Protected_Op): If the context indicates that an access
18131 to a local operation may be transfered outside of the object, create an
18132 access to the wrapper operation that must be used in an external call.
18133 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
18134 target, pass the Valid attribute applied to a floating-point prefix on
18135 to the back end without expansion.
18136 (Storage_Size): Use the new run-time function Storage_Size to retrieve
18137 the allocated storage when it is specified by a per-object expression.
18138 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
18139 Nothing to do here, the attribute has been rewritten during semantic

18143 (Find_Fat_Info): Handle case of universal real
18144 (Expand_Access_To_Protected_Op): Fix use of access to protected
18145 subprogram from inside the body of a protected entry.
18146 (Expand_Access_To_Protected_Op): Common procedure for the expansion of

18148 into a fat pointer.
18149 (Is_Constrained_Aliased_View): New predicate to help determine whether a
18150 subcomponent's enclosing variable is aliased with a constrained subtype.
18151 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
18152 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
18153 an aliased prefix must be known to be constrained in order to use True
18154 for the attribute value, and now it's possible for some aliased views
18155 to be unconstrained.
18157 2006-10-31 Robert Dewar <dewar@adacore.com>
18159 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
18160 (Expand_Entity_Reference): Correct error of not handling subprogram
18161 formals in current_value processing.
18163 2006-10-31 Javier Miranda <miranda@adacore.com>

18166 Gary Dismukes <dismukes@adacore.com>
18168 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
18169 register in the final list objects containing class-wide interfaces;
18170 otherwise we incorrectly register the tag of the interface in the final
18172 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
18173 generate the wrapper if the parent primitive is abstract. This is
18174 required to report the correct error message.
18175 (Expand_N_Subtype_Indication): Do validity checks on range
18176 (Clean_Task_Names): If an initialization procedure includes a call to
18177 initialize a task (sub)component, indicate that the procedure will use
18178 the secondary stack.
18179 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
18180 compatibility for interfacing with CPP by default.
18181 (Expand_N_Object_Declaration): Only build an Adjust call when the
18182 object's type is a nonlimited controlled type.
18183 * exp_ch3.adb: Add with and use of Exp_Ch6.
18184 (Expand_N_Object_Declaration): Check for object initialization that is a
18185 call to build-in-place function and apply Make_Build_In_Place_Call_In_
18186 Object_Declaration to the call.
18187 (Freeze_Type): When the designated type of an RACW was not frozen at the
18188 point where the RACW was declared, validate the primitive operations
18189 with respect to E.2.2(14) when it finally is frozen.
18190 (Build_Initialization_Call,Expand_Record_Controller): Rename
18191 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
18192 return-by-reference has no meaning in Ada 2005.
18193 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
18194 to register tag of the immediate ancestor interfaces in the
18195 run-time structure.
18196 (Init_Secondary_Tags): Moved to the specification to allow the
18197 initialization of extension aggregates with abstract interfaces.
18198 (Build_Master_Renaming): Make public, for use by function declarations
18199 whose return type is an anonymous access type.
18200 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
18201 Insert_List_Before_And_Analyze after the generation of the specs
18202 associated with null procedures.
18203 (Expand_Tagged_Root): Update documentation in its specification.
18204 (Init_Secondary_Tags): Update documentation.
18205 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
18206 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
18207 then generate code to inherit the contents of the dispatch table
18208 directly from the ancestor.
18209 (Expand_Record_Controller): Insert controller component after tags of
18210 implemented interfaces.
18211 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
18212 create null procedure overridings when null procedures are inherited
18214 (Make_Null_Procedure_Specs): New procedure to generate null procedure
18215 declarations for overriding null primitives inherited from interfaces.
18216 (Is_Null_Interface_Procedure): New function in
18217 Make_Null_Procedure_Specs.
18218 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
18219 immediate ancestor of a tagged type is an abstract interface type we
18220 must generate the specification of the predefined primitives associated
18221 with controlled types (because the dispatch table of the ancestor is
18222 null and hence these entries cannot be inherited). This is required to
18223 elaborate well the dispatch table.

18231 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
18233 (Expand_N_In): Do validity checks on range
18234 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
18235 (Expand_N_Allocator): For "new T", if the object is constrained by
18236 discriminant defaults, allocate the right amount of memory, rather than
18237 the maximum for type T.
18238 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
18239 when the allocator is initialized by a build-in-place call, since the
18240 allocator is already rewritten as a reference to the function result,
18241 and this prevents an unwanted duplication of the function call.
18242 Add with and use of Exp_Ch6.
18243 (Expand_Allocator_Expresssion): Check for an allocator whose expression
18244 is a call to build-in-place function and apply
18245 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
18246 untagged designated types).
18247 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
18248 optimization if source or target is biased.
18249 (Expand_N_Allocator): Add comments for case of an allocator within a
18250 function that returns an anonymous access type designating tasks.
18251 (Expand_N_Allocator): apply discriminant checks for access
18252 discriminants of anonymous access types (AI-402, AI-416)

18261 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
18262 (Expand_N_Assignment_Statement): Call
18263 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
18264 build-in-place function call. Currently, this can happen only for
18265 assignments that come from aggregates.
18266 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18267 in order to alleviate the upward compatibility introduced by AI-318.
18268 (Expand_N_Extended_Return_Statement): Add support for handling the
18269 return object as a build-in-place result.
18270 (Expand_Non_Function_Return): Implement simple return statements nested
18271 within an extended return.
18272 (Enable_New_Return_Processing): Turn on the new processing of return
18274 (Expand_Non_Function_Return): For a return within an extended return,
18275 don't raise Program_Error, because Sem_Ch6 now gives a warning.
18276 (Expand_N_Extended_Return_Statement): Implement AI-318
18277 (Expand_Simple_Function_Return): Ditto.
18278 (Expand_N_If_Statement): Handle new -gnatwt warning

18280 (Expand_N_Assignment): Handle assignment to the Priority attribute of
18281 a protected object.
18282 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
18283 validity checking of assignments to elementary record components.
18284 (Expand_N_Return_Statement): return Class Wide types on the secondary
18285 stack independantly of their controlled status since with HIE runtimes,
18286 class wide types are not potentially controlled anymore.
18288 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
18291 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
18292 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
18293 it expects a block, procedure, or task. The return statement will get
18294 turned into a block, and Expand_Cleanup_Actions will happen then.

18298 Bob Duff <duff@adacore.com>
18299 Gary Dismukes <dismukes@adacore.com>
18301 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
18303 (Expand_Inlined_Call): Tagged types are by-reference types, and
18304 therefore should be replaced by a renaming declaration in the expanded
18305 body, as is done for limited types.
18306 (Expand_Call): If this is a call to a function with dispatching access
18307 result, propagate tag from context.
18308 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
18310 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
18311 build-in-place when the right-hand side of an assignment is a
18312 build-in-place function call.
18313 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
18314 of the explicit dereference of the allocator to the result subtype of
18315 the build-in-place function. This is needed to satisfy type checking
18316 in cases where the caller's return object is created by an allocator for
18317 a class-wide access type and the type named in the allocator is a
18319 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
18320 conversion of the reference to the declared object to the result subtype
18321 of the build-in-place function. This is needed to satisfy type checking
18322 in cases where the declared object has a class-wide type. Also, in the
18323 class-wide case, change the type of the object entity to the specific
18324 result subtype of the function, to avoid passing a class-wide object
18325 without explicit initialization to the back end.
18326 (Register_Interface_DT_Entry): Moved outside the body of
18327 Freeze_Subprogram because this routine is now public; it is called from
18328 Check_Dispatching_Overriding to handle late overriding of abstract
18329 interface primitives.
18330 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
18331 adding an implicit access actual on a call to a build-in-place function.
18332 (Expand_Actuals): Test for an actual parameter that is a call to a
18333 build-in-place function and apply
18334 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
18335 (Is_Build_In_Place_Function): New function to determine whether an
18336 entity is a function whose calls should be handled as build-in-place.
18337 (Is_Build_In_Place_Function_Call): New function to determine whether an
18338 expression is a function call that should handled as build-in-place.
18339 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
18340 calls to build-in-place functions as the initialization of an allocator.
18341 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
18342 handling calls to build-in-place functions in contexts that do not
18343 involve init of a separate object (for example, actuals of subprogram
18345 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
18346 handling calls to build-in-place functions as the initialization of an
18347 object declaration.
18348 (Detect_Infinite_Recursion): Add explicit parameter Process to
18349 instantiation of Traverse_Body to avoid unreferenced warning.
18350 (Check_Overriding_Inherited_Interfaces): Removed.
18351 (Register_Interface_DT_Entry): Code cleanup.
18352 (Register_Predefined_DT_Entry): Code cleanup.
18353 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
18354 inlined statements if within a transient scope.
18355 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
18356 formal parameters with occurrences of actuals in inlined body, establish
18357 visibility on the proper view of the actual's subtype for the body's
18359 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
18360 compatibility mode and we have an imported CPP subprogram because
18361 for now we assume that imported CPP primitives correspond with
18362 objects whose constructor is in the CPP side (and therefore we
18363 don't need to generate code to register them in the dispatch table).
18364 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
18365 aligned selected component.
18366 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
18367 the actual of an in-mode parameter is a type conversion.
18368 (Expand_Actuals): If the call does not come from source and the actual
18369 is potentially misaligned, let gigi handle it rather than rejecting the
18370 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
18371 Class Wide types as returning by reference independantly of their
18372 controlled status since with HIE runtimes class wide types are not
18373 potentially controlled anymore.
18375 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18377 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
18378 references that are private components of the protected object.

18380 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
18381 instantiation to deal with warnings.

18383 System_Priority as its expected type, in case the expression has not
18386 2006-10-31 Robert Dewar <dewar@adacore.com>
18388 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
18389 initialization of Homonym_Len.
18390 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
18391 names from fully qualified name. Fixes problem of duplicate
18392 external names differing only in the presence of such a block name.
18394 2006-10-31 Thomas Quinot <quinot@adacore.com>
18395 Pablo Oliveira <oliveira@adacore.com>
18397 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
18398 subprogram Ids, even if they are not yet assigned.
18399 (Build_Subprogram_Id): It is now this function that will take care of
18400 calling Assign_Subprogram_Ids if necessary.
18401 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
18402 should be done only once they are assigned.
18403 (Build_From_Any_Function, case of tagged types): Add missing call to

18406 type for an RACW type.
18407 (Add_RACW_Features): When processing an RACW declaration for which the
18408 designated type is already frozen, enforce E.2.2(14) rules immediately.
18409 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
18410 special reordering of controlling formals.
18412 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
18413 associated stub type for an RACW type.
18415 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18417 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
18418 fixed-point operations in an integer context, i.e. as operands of a
18419 conversion to an integer type, indicate that result must be rounded.
18421 2006-10-31 Robert Dewar <dewar@adacore.com>
18423 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
18424 cases, pass the encoding method, since it is now required by the run
18427 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
18428 assumption that Str'First = 1.
18429 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
18430 it on to the Value_Wide_Wide_Character call.
18431 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
18432 properly handles a string of the form quote-encoded_wide_char-quote.
18434 * s-wchcnv.adb: Minor reformatting
18436 2006-10-31 Javier Miranda <miranda@adacore.com>
18438 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
18439 run-time membership test to ensure that the constructed object
18440 implements the target abstract interface.
18442 2006-10-31 Robert Dewar <dewar@adacore.com>
18444 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
18445 Machine_Attribute pragma internally to implement the user pragma.
18446 Add processing for pragma Interface so that it is now completely
18447 equivalent to pragma Import.
18449 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
18450 so that it can be applied to all entities, including record components
18451 and enumeration literals.
18452 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
18453 priority ranges are correct, verify compatibility against task
18454 dispatching and locking policies, and if everything is correct an entry
18455 is added to the table containing priority specific dispatching entries
18456 for this compilation unit.
18457 (Delay_Config_Pragma_Analyze): Delay processing
18458 Priority_Specific_Dispatching pragmas because when processing the
18459 pragma we need to access run-time data, such as the range of
18460 System.Any_Priority.
18461 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
18462 Allow pragma Unreferenced as a context item
18463 Add pragma Preelaborable_Initialization
18464 (Analyze_Pragma, case Interface): Interface is extended so that it is
18465 now syntactically and semantically equivalent to Import.
18466 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
18467 insertion characters.
18468 Add handling for Pragma_Wide_Character_Encoding
18469 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
18470 never supercedes a real restriction, and that a real restriction
18471 always supercedes a warning.
18472 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

18477 Robert Dewar <dewar@adacore.com>
18479 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
18480 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
18481 Is_Inherently_Limited_Type, because return-by-reference has no meaning
18483 (Find_Node_To_Be_Wrapped): Use new method of determining the result
18484 type of the function containing a return statement, because the
18485 Return_Type field was removed. We now use the Return_Applies_To field.
18487 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
18488 (Build_Task_Image_Decl): If procedure is not called from an
18489 initialization procedure, indicate that function that builds task name
18490 uses the sec. stack. Otherwise the enclosing initialization procedure
18491 will carry the indication.
18492 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
18493 N_Object_Declaration instead.
18494 (Kill_Dead_Code): New interface to implement -gnatwt warning for
18495 conditional dead code killed, and change implementation accordingly.
18496 (Insert_Actions): Add N_Return_Object_Declaration case.
18497 Correct comment to mention N_Extension_Aggregate node.
18498 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
18499 attempts to save information for global variables which cannot be
18501 (Get_Current_Value_Condition): Handle conditions the other way round
18502 (constant on left). Also handle right operand of AND and AND THEN
18503 (Set_Current_Value_Condition): Corresponding changes
18504 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
18505 (Get_Current_Value_Condition): Handle simple boolean operands
18506 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
18507 (Get_Current_Value_Condition): If the variable reference is within an
18508 if-statement, does not appear in the list of then_statments, and does
18509 not come from source, treat it as being at unknown location.
18510 (Get_Current_Value_Condition): Enhance to allow while statements to be
18511 processed as well as if statements.
18512 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
18514 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
18515 of loop. This is safe now that we fixed Kill_Current_Values.
18516 (OK_To_Do_Constant_Replacement): Check whether current scope is
18517 Standard, before examining outer scopes.
18519 2006-10-31 Vincent Celier <celier@adacore.com>
18521 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
18522 When True, apply VMS treatment to children of packages A, G, I and S.
18525 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
18527 2006-10-31 Robert Dewar <dewar@adacore.com>
18528 Ed Schonberg <schonberg@adacore.com>
18530 * freeze.adb: Add handling of Last_Assignment field
18531 (Warn_Overlay): Supply missing continuation marks in error msgs
18532 (Freeze_Entity): Add check for Preelaborable_Initialization
18534 * g-comlin.adb: Add Warnings (Off) to prevent new warning
18536 * g-expect.adb: Add Warnings (Off) to prevent new warning
18538 * lib-xref.adb: Add handling of Last_Assignment field
18539 (Generate_Reference): Centralize handling of pragma Obsolescent here
18540 (Generate_Reference): Accept an implicit reference generated for a
18541 default in an instance.
18542 (Generate_Reference): Accept a reference for a node that is not in the
18543 main unit, if it is the generic body corresponding to an subprogram
18546 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
18548 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
18550 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18552 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18553 use clauses, to avoid messages on packages used to qualify, and also
18554 to avoid messages from obsolescent units.
18555 (Warn_On_Useless_Assignments): Don't generate messages for imported
18556 and exported variables.
18557 (Warn_On_Useless_Assignments): New procedure
18558 (Output_Obsolescent_Entity_Warnings): New procedure
18559 (Check_Code_Statement): New procedure
18561 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag

18563 (Last_Assignment): New field for useless assignment warning
18565 2006-10-31 Olivier Hainque <hainque@adacore.com>
18567 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18568 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18570 2006-10-31 Bob Duff <duff@adacore.com>
18571 Robert Dewar <dewar@adacore.com>
18572 Ed Schonberg <schonberg@adacore.com>
18574 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18575 Ada 95 mode, because it violates the new rules for AI-318.
18577 * g-awk.ads: Use overloaded subprograms in every case where we used to
18578 have a default of Current_Session. This makes the code closer to be
18579 correct for both Ada 95 and 2005.
18581 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18582 code, relying on the fact that the compiler generates a warning
18583 instead of an error in -gnatg mode.
18585 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18586 E_Return_Statement entity kind.
18587 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18589 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18590 report an error if the reserved word abstract has been previously found.
18591 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18593 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18594 parenthesized range attribute usage
18595 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18597 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18598 in the syntax for extended_return_statement. This is not in the latest
18599 RM, but the ARG is expected to issue an AI allowing this.
18600 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18601 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18602 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18603 P_Return_Statement): Parse the new syntax for extended_return_statement.
18605 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18606 Output_End_Missing): Add error-recovery code for the new
18607 extended_return_statement syntax; that is, the new E_Return entry on
18610 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18611 limited to nonlimited, because otherwise we violate the new Ada 2005
18612 rules about returning limited types in function Create_AST_Handler in
18615 * sem.adb (Analyze): Add cases for new node kinds
18616 N_Extended_Return_Statement and N_Return_Object_Declaration.
18618 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18619 type is in the same category as type of context before applying check,
18620 to prevent anomalies in instantiations.
18621 (Resolve_Aggregate): Remove test for limited components in aggregates.
18622 It's unnecessary in Ada 95, because if it has limited components, then
18623 it must be limited. It's wrong in Ada 2005, because limited aggregates
18625 (Resolve_Record_Aggregate): Move check for limited types later, because
18626 OK_For_Limited_Init requires its argument to have been resolved.
18627 (Get_Value): When copying the component default expression for a
18628 defaulted association in an aggregate, use the sloc of the aggregate
18629 and not that of the original expression, to prevent spurious
18630 elaboration errors, when the expression includes function calls.
18631 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18632 were missing. We also didn't handle qualified expressions. Now also
18633 allow function calls. Use new common routine OK_For_Limited_Init.
18634 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18635 with space can upper case letter).
18637 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18638 Has_Static_Discriminants flag
18639 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18640 type with discriminants.
18641 (Process_Range_Expr_In_Decl): Do validity checks on range
18642 (Build_Discriminant_Constraints): Use updated form of
18643 Denotes_Discriminant.
18644 (Process_Subtype): If the subtype is a private subtype whose full view
18645 is a concurrent subtype, introduce an itype reference to prevent scope
18647 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18648 Record_Type_Declaration): The functionality of the subprograms
18649 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18650 is now performed by a single routine.
18651 (Build_Derived_Record_Type): If the type definition includes an explicit
18652 indication of limitedness, then the type must be marked as limited here
18653 to ensure that any access discriminants will not be treated as having
18654 a local anonymous access type.
18655 (Check_Abstract_Overriding): Issue a detailed error message when an
18656 abstract subprogram was not overridden due to incorrect mode of its
18658 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18659 synchronized private extension declarations. Verify that the ancestor is
18660 a limited or synchronized interface or in the generic case, the ancestor
18661 is a tagged limited type or synchronized interface and all progenitors
18662 are either limited or synchronized interfaces.
18663 Derived_Type_Declaration): Check for presence of private extension when
18664 dealing with synchronized formal derived types.
18665 Process_Full_View): Enchance the check done on the usage of "limited" by
18666 testing whether the private view is synchronized.
18667 Verify that a synchronized private view is completed by a protected or
18669 (OK_For_Limited_Init_In_05): New function.
18670 (Analyze_Object_Declaration): Move check for limited types later,
18671 because OK_For_Limited_Init requires its argument to have been resolved.
18672 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18673 in order to alleviate the upward compatibility introduced by AI-318.
18674 (Constrain_Corresponding_Record): If the constraint is for a component
18675 subtype, mark the itype as frozen, to avoid out-of-scope references to
18676 discriminants in the back-end.
18677 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18678 this subprogram against wrong sources.
18679 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18680 discriminant of limited type completed with a protected type, when the
18681 discriminant is used to constrain a private component of the type, and
18682 expansion is disabled.
18683 (Find_Type_Of_Object): Do not treat a return subtype that is an
18684 anonymous subtype as a local_anonymous_type, because its accessibility
18685 level is the return type of the enclosing function.
18686 (Check_Initialization): In -gnatg mode, turn the error "cannot
18687 initialize entities of limited type" into a warning.
18688 (OK_For_Limited_Init): Return true for generated nodes, since it
18689 sometimes violates the legality rules.
18690 (Make_Incomplete_Declaration): If the type for which an incomplete
18691 declaration is created happens to be the currently visible entity,
18692 preserve the homonym chain when removing it from visibility.
18693 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18694 inherited subprograms.
18695 (Access_Definition): If this is an access to function that is the return
18696 type of an access_to_function definition, context is a type declaration
18697 and the scope of the anonymous type is the current one.
18698 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18699 incomplete subtype to the set of private dependents of the original
18701 (Constrain_Discriminated_Type): Emit an error message whenever an
18702 incomplete subtype is being constrained.
18703 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18704 corresponding subtype of the full view of the original incomplete type.
18705 (Check_Incomplete): Properly detect invalid usage of incomplete types
18708 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18710 * g-catiio.ads, g-catiio.adb (Value): New function.

18719 Robert Dewar <dewar@adacore.com>
18721 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18722 handling executable extension manually and duplicating code.
18724 * make.adb: Implement new -S switch
18725 (Gnatmake): Use new function Osint.Executable_Name instead
18726 of handling executable extension manually.
18728 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18729 is specified, the executable name ends with this suffix.
18730 Take advantage of Osint.Executable_Name instead of duplicating code.
18732 * switch-m.adb: Recognize new gnatmake -S switch
18734 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18736 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18739 * makeusg.adb: Add line for gnatmake -S switch
18741 2006-10-31 Vincent Celier <celier@adacore.com>
18743 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18744 call it with -static-libgcc, as there are some platforms, such as
18745 Darwin, where one of these two switches is compulsory to link.
18747 2006-10-31 Vincent Celier <celier@adacore.com>
18749 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18750 instead of ADA_PROJECT_PATH, for the project path.
18751 (Gnatls): When displaying the project path directories, use host dir
18754 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18755 names in the project path, as absolute paths may correspond to
18756 multi-valued VMS logical names.
18758 2006-10-31 Vincent Celier <celier@adacore.com>
18760 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18761 absolute path name.
18762 (Locate_Regular_File): Ditto
18763 (Change_Dir): Remove, no longer used
18764 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18765 on Windows. Get it calling Get_Current_Dir.
18766 (OpenVMS): Remove imported boolean, no longer needed.
18767 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18768 (Pid_To_Integer): New function to convert a Process_Id to Integer
18770 2006-10-31 Thomas Quinot <quinot@adacore.com>
18772 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18773 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18775 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18778 2006-10-31 Robert Dewar <dewar@adacore.com>
18780 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
18781 initial letter o as a zero.

18785 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
18787 2006-10-31 Robert Dewar <dewar@adacore.com>
18789 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18791 (Layout_Variant_Record): Retrieve the discriminants from the entity
18792 rather than from the type definition, because in the case of a full
18793 type for a private type we need to take the discriminants from the
18795 (Layout_Component_List): When applying the Max operator to variants with
18796 a nonstatic size, check whether either operand is static and scale that
18797 operand from bits to storage units before applying Max.
18798 (Layout_Type): In VMS, if a C-convention access type has no explicit
18799 size clause (and does not inherit one in the case of a derived type),
18800 then the size is reset to 32 from 64.
18802 2006-10-31 Vincent Celier <celier@adacore.com>
18804 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18805 its file has already been loaded, according to the unit being loaded,
18806 not to the current value of Multiple_Unit_Index.
18808 2006-10-31 Thomas Quinot <quinot@adacore.com>
18809 Eric Botcazou <ebotcazou@adacore.com>
18810 Arnaud Charlet <charlet@adacore.com>
18812 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
18813 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if

18821 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
18822 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
18823 Ada.Dispatching.Round_Robin.
18824 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
18826 * Make-lang.in: Remove all references to gt-ada-decl.h.
18827 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler

18834 2006-10-31 Vincent Celier <celier@adacore.com>
18836 * mlib-utl.adb (Initialized): Remove, no longer used
18837 (Initialize): Remove, no longer used
18838 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18839 if there is one, the archive indexer. Fail if the archive builder cannot
18841 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18844 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18846 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18847 Process_Body_Clauses): If the context of a body includes a use clause
18848 for P.Q then a with_clause for P in the same body is not redundant,
18849 even if the spec also has a with_clause on P.
18850 Add missing continuation mark to error msg
18851 (Build_Limited_Views): A limited view of a type is tagged if its
18852 declaration includes a record extension.
18853 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18854 node, even if the subunit has errors. This avoids malfunction by
18855 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18856 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18857 generation of obsolescent messages for with statements (cannot do
18858 this too early, or we cannot implement avoiding the messages in the
18859 case of obsolescent units withing obsolescent units).
18860 (Install_Siblings): If the with_clause is on a remote descendant of
18861 an ancestor of the current compilation unit, find whether there is
18862 a sibling child unit that is immediately visible.
18863 (Remove_Private_With_Clauses): New procedure, invoked after completing
18864 the analysis of the private part of a nested package, to remove from
18865 visibility the private with_clauses of the enclosing package
18867 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18868 now centralized in Generate_Reference.
18869 (Install_Limited_Context_Clauses): Remove superfluous error
18870 message associated with unlimited view visible through use
18871 and renamings. In addition, at the point in which the error
18872 is reported, we add the backslash to the text of the error
18873 to ensure that it is reported as a single error message.
18874 Use new // insertion for some continuation messages
18875 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18876 to create implicit with_clause for parent unit mentioned in original
18877 limited_with_clause.
18878 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18879 unit is a child unit. For ASIS queries.
18880 (Analyze_Subunit): If the subunit appears within a child unit, make all
18881 ancestor child units directly visible again.
18883 2006-10-31 Robert Dewar <dewar@adacore.com>

18896 a formal object declaration with an access definition or a subtype mark
18897 with a null exclusion.
18898 (P_Generic_Association): Handle association with box, and others_choice
18899 with box, to support Ada 2005 partially parametrized formal packages.
18901 2006-10-31 Robert Dewar <dewar@adacore.com>
18902 Javier Miranda <miranda@adacore.com>
18904 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18905 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18906 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18907 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18908 private extensions.
18909 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18910 to P_Interface_Type_Definition.
18911 (P_Interface_Type_Definition): Addition of one formal to report an error
18912 if the reserved word abstract has been previously found.

18939 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18940 on VMS, change "__" to '.' before checking the name.
18941 (Record_Ada_Source): Always add the source file name in the list of
18942 of sources, even if it is not the first time, as it is for another
18944 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18945 dot, instead of replacing only the first '_'.
18947 * prj-part.adb (Parse): Convert project file path to canonical form
18949 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18950 extended, the project id of the project extending it is recorded in its
18951 data, even when it has already been processed as an imported project.

18959 Robert Dewar <dewar@adacore.com>
18961 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18962 only a restriction warning is active for the given restriction. This is
18963 desirable because we do not want to modify code in the case where only
18965 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18966 causes overriding of real restrictions.
18967 Take advantage of new No_Restrictions constant.
18969 * raise.h: (__gnat_set_globals): Change profile.
18971 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18973 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18976 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18977 Move all the entities in obsolete package System.PolyORB_Interface to
18978 System.Partition_Interface.

18996 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18997 properly an attempt to apply Unchecked_Access to a protected operation.
18998 (OK_Self_Reference): New subprogram to check the legality of an access
18999 attribute whose prefix is the type of an enclosing aggregate.
19000 Generalizes previous mechanism to handle attribute references nested
19001 arbitrarily deep within the aggregate.
19002 (Analyze_Access_Attribute): An access attribute whose prefix is a type
19003 can appear in an aggregate if this is a default-initialized aggregate
19004 for a self-referential type.
19005 (Resolve_Attribute, case Access): Ditto.
19006 Add support for new implementation defined attribute Stub_Type.

19011 Has_Specified_Stream_Attribute flag.
19012 Disallow Storage_Size and Storage_Pool for access to subprogram
19013 (Resolve_Attribute, case 'Access et al): Take into account anonymous
19014 access types of return subtypes in extended return statements. Remove
19015 accessibility checks on anonymous access types when Unchecked_Access is
19017 (Analyze_Attribute): Add support for the use of 'Class to convert
19018 a class-wide interface to a tagged type.
19019 Add support for the attribute Priority.
19020 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
19021 whether the designated type is discriminated with a constrained partial
19022 view and require static matching in that case.
19023 Add local variable Des_Btyp. The Designated_Type
19024 of an access to incomplete subtype is either its non-limited view if
19025 coming from a limited with or its etype if regular incomplete subtype.
19027 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
19028 Fix predicate to identify and allow cases of (expander-generated)
19029 references to tag of designated object of a RACW.
19030 (Validate_Static_Object_Name): In Ada 2005, a formal object is
19031 non-static, and therefore cannot appear as a primary in a preelaborable
19033 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
19034 Has_Read_Write_Attributes.
19035 (Has_Read_Write_Attributes): Reimplement in termes of
19036 Has_Stream_Attribute_Definition.
19037 (Missing_Read_Write_Attributes): When checking component types in a
19038 record, unconditionally call Missing_Read_Write_Attributes recursively
19039 (remove guard checking for Is_Record_Type / Is_Access_Type).
19041 2006-10-31 Robert Dewar <dewar@adacore.com>
19043 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
19044 useless assignments here and conditionalize it on absence of exception

19047 detection code, for new handling of formal packages.
19049 2006-10-31 Ed Schonberg <schonberg@adacore.com>
19050 Hristian Kirtchev <kirtchev@adacore.com>
19052 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
19053 that has been constant-folded, preserve information of original tree,
19055 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
19056 generated private extension declaration if the formal derived type is
19057 synchronized. Carry synchronized present over to the generated private
19059 (Validate_Derived_Type_Instance): Ensure that the actual of a
19060 synchronized formal derived type is a synchronized tagged type.
19061 (Instantiate_Formal_Package): When creating the instantiation used to
19062 validate the actual package of a formal declared without a box, check
19063 whether the formal itself depends on a prior actual.
19064 (Instantiate_Formal_Subprogram): Create new entities for the defining
19065 identifiers of the formals in the renaming declaration, for ASIS use.
19066 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
19067 a renaming declaration or a subtype declaration for an actual in an
19068 instance, capture location information of declaration in generic, for
19070 (Instantiate_Formal_Package): Add comments on needed additional tests.
19071 AI-317 (partial parametrization) is fully implemented.
19072 (Validate_Private_Type_Instance): Add check for actual which
19073 must have preelaborable initialization
19074 Use new // insertion for some continuation messages
19075 (Analyze_Formal_Object_Declaration): Change usage of Expression to
19076 Default_Expression. Add type retrieval when the declaration has an
19077 access definition. Update premature usage of incomplete type check.
19078 (Check_Access_Definition): New subsidiary routine. Check whether the
19079 current compilation version is Ada 05 and the supplied node has an
19081 (Instantiate object): Alphabetize local variables. Handle the creation
19082 of new renaming declarations with respect to the kind of definition
19083 used - either an access definition or a subtype mark. Guard against
19084 unnecessary error message in the context of anonymous access types after
19085 they have been resolved. Add check for required null exclusion in a
19086 formal object declaration.
19087 (Switch_View): A private subtype of a non-private type needs to be
19088 switched (the base type can have been switched without its private
19089 dependents because of the last branch of Check_Private_View.
19090 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
19092 (Instantiate_Type): Emit an error message whenever a class-wide type of
19093 a tagged incomplete type is used as a generic actual.
19094 (Find_Actual_Type): Extend routine to handle a component type in a child
19095 unit that is imported from a formal package in a parent.
19096 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
19097 agree on constrainedness, rather than checking against ultimate ancestor
19098 (Instantiate_Subprogram_Body): Create a cross-reference link to the
19099 generic body, for navigation purposes.
19101 2006-10-31 Robert Dewar <dewar@adacore.com>
19102 Thomas Quinot <quinot@adacore.com>
19104 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
19106 (New_Stream_Subprogram): When processing an attribute definition clause
19107 for a stream-oriented subprogram, record an entity node occurring at
19108 the point of clause to use for checking the visibility of the clause,
19109 as defined by 8.3(23) as amended by AI-195.
19110 (New_Stream_Subprogram): New procedure, factoring behaviour from both
19111 New_Stream_Function and New_Stream_Procedure.
19112 (New_Stream_Function, New_Stream_Procedure): Removed.
19113 (Analyze_Attribute_Definition_Clause, case Address): Check new
19114 Alignment_Check check

19117 Javier Miranda <miranda@adacore.com>
19118 Robert Dewar <dewar@adacore.com>
19120 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
19121 generate the same errors compiling under -gnatc.
19122 (Try_Object_Operation): If no candidate interpretation succeeds, but
19123 there is at least one primitive operation with the right name, report
19124 error in call rather than on a malformed selected component.
19125 (Analyze_Selected_Component): If the prefix is an incomplete type from
19126 a limited view, and the full view is available, use the full view to
19127 determine whether this is a prefixed call to a primitive operation.
19128 (Operator_Check): Verify that a candidate interpretation is a binary
19129 operation before checking the type of its second formal.
19130 (Analyze_Call): Add additional warnings for function call contexts not
19132 (Analyze_Allocator): Move the check for "initialization not allowed for
19133 limited types" after analyzing the expression. This is necessary,
19134 because OK_For_Limited_Init looks at the structure of the expression.
19135 Before analysis, we don't necessarily know what sort of expression it
19136 is. For example, we don't know whether F(X) is a function call or an
19137 indexed component; the former is legal in Ada 2005; the latter is not.
19138 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
19139 were missing. We also didn't handle qualified expressions. Now also
19140 allow function calls. Use new common routine OK_For_Limited_Init.
19141 (Analyze_Type_Conversion): Do not perform some legality checks in an
19142 instance, because the error message will be redundant or spurious.
19143 (Analyze_Overloaded_Selected_Component): Do not do style check when
19144 setting an entity, since we do not know it is the right entity yet.
19145 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
19146 (Analyze_Overloaded_Selected_Component): Same change
19147 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
19148 since regular incomplete subtypes are transformed into corresponding
19149 subtypes of their full views.
19150 (Complete_Object_Operation): Treat name of transformed subprogram call
19151 as coming from source, for browsing purposes.
19152 (Try_Primitive_Operation): If formal is an access parameter, compare
19153 with base type of object to determine whether it is a primitive
19155 (Operator_Check): If no interpretation of the operator matches, check
19156 whether a use clause on any candidate might make the operation legal.
19157 (Try_Class_Wide_Operation): Check whether the first parameter is an
19158 access type whose designated type is class-wide.

19165 warn on infinite loops.
19166 Add \\ to some continuation messages
19167 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
19168 (Process_Bounds): If the bounds are integer literals that result from
19169 constant-folding, and they carry a user-defined type, preserve that type
19170 rather than treating this as an integer range.
19171 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
19172 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
19173 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
19174 left hand side of assignment.
19175 (Analyze_Assignment): Add suport to manage assigments to the attribute
19176 priority of a protected object.
19177 (Check_Possible_Current_Value_Condition): Allow fully qualified names
19178 not just identifiers.
19179 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
19180 or AND THEN for possible tracking.
19181 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
19182 case of while loops so we can track values in the loop body.

19185 Hristian Kirtchev <kirtchev@adacore.com>
19186 Bob Duff <duff@adacore.com>
19188 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
19189 procedure cannot be a protected operation (it is a basic_declaration,
19190 not a subprogram_declaration).
19191 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
19192 Subp. Add logic for entry processing.
19193 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
19194 Determine whether an entry or subprogram of a protected or task type
19195 override an inherited primitive of an implemented interface.
19196 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
19197 Update the actual used in calls to Check_Overriding_Indicator.
19198 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
19199 generate the proper reference to the parent unit, for cross-reference.
19200 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
19202 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
19203 (Add_Extra_Formal): Revise procedure to allow passing in associated
19204 entity, scope, and name suffix, and handle setting of the new
19205 Extra_Formals field.
19206 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
19207 pass new parameters. Add support for adding the new extra access formal
19208 for functions whose calls are treated as build-in-place.
19209 (Analyze_A_Return_Statement): Correct casing in error message.
19210 Move Pop_Scope to after Analyze_Function_Return, because an extended
19211 return statement really is a full-fledged scope. Otherwise, visibility
19212 doesn't work right. Correct use of "\" for continuation messages.
19213 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
19214 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
19215 the node doesn't get properly marked as analyzed.
19216 (Analyze_Subprogram_Body): If subprogram is a function that returns
19217 an anonymous access type that denotes a task, build a Master Entity
19219 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
19220 proper usage of null exclusion in a result definition.
19221 (Process_Formals): Code cleanup and new error message.
19222 (Process_Formals): Detect incorrect application of null exclusion to
19224 (Conforming_Types): Handle conformance between [sub]types and itypes
19225 generated for entities that have null exclusions applied to them.
19226 (Maybe_Primitive_Operation): Add an additional type retrieval when the
19227 base type is an access subtype. This case arrises with null exclusions.
19228 (New_Overloaded_Entity): Do not remove the overriden entity from the
19229 homonym chain if it corresponds with an abstract interface primitive.
19230 (Process_Formals): Replace membership test agains Incomplete_Kind with a
19231 call to the synthesized predicate Is_Incomplete_Type.
19232 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
19234 (Analyze_Subprogram_Declaration): Check that abstract interface
19235 primitives are abstract or null.
19236 (Analyze_Subprogram_Specification): Remove previous check for abstract
19237 interfaces because it was not complete.
19238 (Has_Interface_Formals): Removed.
19240 2006-10-31 Ed Schonberg <schonberg@adacore.com>
19241 Javier Miranda <miranda@adacore.com>
19243 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
19244 of Analyze_Package_Body, to create Itype references for anonymous
19245 access types created in the package declaration, whose designated types
19246 may have only a limited view.
19247 (Analyze_Package_Specification): For the private part of a nested
19248 package, install private_with_clauses of enclosing compilation unit if
19249 we are in its visible part.
19250 (Declare_Inherited_Private_Subprograms): Complete barrier
19251 to ensure that the primitive operation has an alias to some parent
19252 primitive. This is now required because, after the changes done for the
19253 implementation of abstract interfaces, the contents of the list of
19254 primitives has entities whose alias attribute references entities of
19255 such list of primitives.
19256 (Analyze_Package_Specification): Simplify code that handles parent units
19257 of instances and formal packages.
19258 (Uninstall_Declarations): Check the convention consistency among
19259 primitive overriding operations of a tagged record type.

19270 (Analyze_Generic_Renaming): Same fix
19271 (Use_One_Package): Do not take into account the internal entities of
19272 abstract interfaces during the analysis of entities that are marked
19273 as potentially use-visible.
19274 (Find_Type): Handle the case of an attribute reference for
19275 implementation defined attribute Stub_Type (simply let the analysis of
19276 the attribute reference rewrite it).
19277 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
19278 type that appears in a Use_Type clause.
19279 (Analyze_Object_Renaming): Add support for renaming of the Priority
19281 (Find_Type): In Ada 2005, a task type can be used within its own body,
19282 when it appears in an access definition.
19283 (Analyze_Object_Renaming): Remove warning on null_exclusion.
19284 (Analyze_Object_Renaming): Introduce checks for required null exclusion
19285 in a formal object declaration or in a subtype declaration.
19286 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
19287 (Check_Null_Exclusion): New local routine to
19288 Analyze_Subprogram_Renaming. Check whether the formals and return
19289 profile of a renamed subprogram have required null exclusions when
19290 their counterparts of the renaming already impose them.
19291 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
19292 Determine whether an entity is inside a generic scope.
19293 (In_Open_Scope): First pass of documentation update.
19294 (Find_Expanded_Name): Add support for shadow entities associated with
19295 limited withed packages. This is required to handle nested packages.
19296 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
19297 that makes a renaming of a limited withed package illegal.

19303 Check_Overriding_Indicator.
19304 (Analyze_Task_Definition): Ditto.
19305 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
19306 (Check_Overriding_Indicator): To find overridden interface operation,
19307 examine only homonyms that have an explicit subprogram declaration, not
19308 inherited operations created by an unrelated type derivation.
19309 (Check_Overriding_Indicator): When checking for the presence of "null"
19310 in a procedure, ensure that the queried node is a procedure
19312 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
19313 type when the formal is an access to variable.
19314 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
19315 (Analyze_Task_Type): Same addition
19316 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to

19324 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
19325 inherited from an interface ancestor by another interface in the
19326 context of an instance as 'late'.
19327 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
19328 of a call to a function that dispatches on access result.
19329 (Check_Dispatching_Operation): In case of late overriding of a primitive
19330 that covers abstract interface subprograms we register it in all the
19331 secondary dispatch tables associated with abstract interfaces.
19332 (Check_Dispatching_Call): Add check that a dispatching call is not made
19333 to a function with a controlling result of a limited type. This is a
19334 current implementation restriction.
19335 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
19336 (Check_Dispatching_Operation): Do no emit a warning if the controlling
19337 argument is an interface type that is a generic formal.
19338 (Is_Interface_Subprogram): Removed.
19339 (Check_Dispatching_Operation): If the subprogram is not a dispatching
19340 operation, check the formals to handle the case in which it is
19341 associated with an abstract interface type.

20154 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
20155 abstract interface type, the static analysis is not enough to know if

20157 we must pass the work to the expander to generate the required code to
20158 evaluate the conversion at run-time.
20159 (Resolve_Equality_Op): Do not apply previous

20816 (Scan_Make_Switches): Do not allow numeric debug switches for gnatmake
20817 (Scan_Make_Switches): When failing with an illegal switch, output an
20818 error message with the full switch.
20819 Eliminate numeric switches for binder/gnatmake
20821 * switch.ads, switch.adb (Bad_Switch): New procedure
20823 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
20824 Remove 0-9 as debug flag character possibilities
20825 -d is now controlling the primary stack size when its value is a
20826 positive. Also add checks against invalid values, and support for kb,
20827 mb. Ditto for -D switch.
20829 2006-02-13 Robert Dewar <dewar@adacore.com>
20830 Serguei Rybin <rybin@adacore.com>
20832 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
20833 save/restore routines.
20834 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20835 were not always properly handled previously.
20836 Since we are changing the tree format anyway, also get rid of the
20837 junk obsolete Immediate_Errors flag.
20838 (Tree_Read): Change the way of reading Tree_Version_String - now we
20839 read the version string from the tree even if its length is not the
20840 same as the length of the version string computed from Gnatvsn.
20841 (Search_Directory_Present): New Boolean flag for the compiler.
20842 Define Tree_Version_String as a dynamic string.
20843 (Default_Stack_Size): new variable, used to handle switch -d.
20846 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
20847 only for main unit.
20848 Add pragma Ada_2005 (synonym for Ada_05)
20849 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20850 were not always properly handled previously.
20852 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
20853 explicit Ada_95 to Ada_2005.
20855 2006-02-13 Javier Miranda <miranda@adacore.com>
20856 Robert Dewar <dewar@adacore.com>
20857 Ed Schonberg <schonberg@adacore.com>
20859 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
20860 against errors in the source program: a private types for which the
20861 corresponding full type declaration is missing and pragma CPP_Virtual
20863 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
20864 (Is_Known_Null): New flag
20865 (Has_Pragma_Pure): New flag
20866 (No_Return): Present in all entities, set only for procedures
20867 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20868 explicitly declared limited.
20869 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20870 entities. Only used for component marked Is_Tag. If present it stores
20871 the Offset_To_Top function used to provide this value in tagged types
20872 whose ancestor has discriminants.
20874 * exp_ch2.adb: Update status of new Is_Known_Null flag
20876 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
20878 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
20879 the categorization sense if Is_Pure was set by pragma Pure_Function.
20881 2006-02-13 Quentin Ochem <ochem@adacore.com>
20882 Olivier Hainque <hainque@adacore.com>
20884 * bindusg.adb: Updated documentation for -d and -D switches.
20886 * raise.h (__gnat_set_globals): added new parameter for
20887 Default_Stack_Size.
20889 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
20890 (__gnat_handle_vms_condition): Adjust context before raise.
20891 (__gnat_install_handler): Restore the global vector setup for GCC
20892 versions before 3.4, as the frame based circtuitry is not available
20894 (__gnat_set_globals): added a parameter default_stack_size
20895 (__gl_default_stack_size): new variable.
20897 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20899 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20900 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20901 does not exist in the Ada RM.
20902 (Compatible_Int_Bounds): Determine whether two integer range bounds
20903 are of equal length and have the same start and end values.
20904 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20905 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20906 aggregate when it is part of an object declaration.
20907 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20908 constrains discriminants of its parent, add explicitly the discriminant
20909 constraints of the ancestor by retrieving them from the
20910 stored_constraint of the parent.
20912 2006-02-13 Robert Dewar <dewar@adacore.com>
20914 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20915 attribute Mechanism_Code is applied to renamed subprogram, modify
20916 prefix to point to base subprogram.
20917 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20919 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20920 renamed subprograms so that the front-end must replace the prefix
20923 2006-02-13 Javier Miranda <miranda@adacore.com>
20924 Gary Dismukes <dismukes@adacore.com>
20926 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20927 availability of RE_Interface_Tag.
20928 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20929 (Freeze_Record_Type): Do not generate the tables associated with
20930 timed and conditional dispatching calls through synchronized
20931 interfaces if compiling under No_Dispatching_Calls restriction.
20932 When compiling for Ada 2005, for a nonabstract
20933 type with a null extension, call Make_Controlling_Function_Wrappers
20934 and insert the wrapper function declarations and bodies (the latter
20935 being appended as freeze actions).
20936 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20937 predefined primitives associated with timed and conditional
20938 dispatching calls through synchronized interfaces if we are
20939 compiling under No_Dispatching_Calls.
20940 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20941 service is available before generating a call.
20942 (Make_Controlling_Function_Wrappers): New procedure.
20943 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20944 access-to-limited-interfaces because they can be used to reference
20945 tasks that implement such limited interface.
20946 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20947 procedure spec and body of the Offset_To_Top function that is generated
20948 when the parent of a type with discriminants has secondary dispatch
20950 (Init_Secondary_Tags): Handle the case in which the parent of the type
20951 containing secondary dispatch tables has discriminants to generate the
20952 correct arguments to call Set_Offset_To_Top.
20953 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20955 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20956 Add Wide_[Wide_]Expanded_Name.
20957 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20958 the same functionality of Get_Prim_Op_Address but applied to predefined
20959 primitive operations because the pointers to the predefined primitives
20960 are now saved in a separate table.
20961 (Parent_Size): Modified to get access to the separate table of primitive
20962 operations or the parent type.
20963 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20964 functionality of Set_Prim_Op_Address but applied to predefined primitive
20966 (Set_Signature): New subprogram used to store the signature of a DT.
20967 (Displace): If the Offset_To_Top value is not static then call the
20968 function generated by the expander to get such value; otherwise use
20969 the value stored in the table of interfaces.
20970 (Offset_To_Top): The type of the actual has been changed to Address to
20971 give the correct support to tagged types with discriminants. In this
20972 case this value is stored just immediately after the tag field.
20973 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20974 offset_to_top value is static and hence pass this value to the run-time
20975 to store it in the table of interfaces, or else if this value is dynamic
20976 and then pass to the run-time the address of a function that is
20977 generated by the expander to provide this value for each object of the
20980 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20981 (Default_Prim_Op_Count): New entity
20982 (Get_Predefined_Prim_Op_Address): New entity
20983 (Set_Predefined_Prim_Op_Address): New entity
20984 (RE_Set_Signature): New entity
20986 2006-02-13 Thomas Quinot <quinot@adacore.com>
20987 Ed Schonberg <schonberg@adacore.com>
20989 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20990 Make_Adjust_Call done for a newly-allocated object.
20992 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20993 in a subprogram are wrapped in a cleanup block, indicate that the
20994 subprogram contains an inner block with an exception handler.
20995 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20996 Adjust call is for a newly-allocated object. In that case we must not
20997 assume that the finalization list chain pointers are correct (since they
20998 come from a bit-for-bit copy of the original object's pointers) so if
20999 the attach level would otherwise be zero (no change), we set it to 4
21000 instead to cause the pointers to be reset to null.
21002 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
21003 reset chain pointers to null.
21005 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21007 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
21008 string, and the context requires a loop for the assignment (e.g.
21009 because the left-hand side is packed), generate a unique name for the
21010 temporary that holds the string, to prevent spurious name clashes.
21012 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21013 Javier Miranda <miranda@adacore.com>
21014 Robert Dewar <dewar@adacore.com>
21015 Gary Dismukes <dismukes@adacore.com>
21017 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
21018 return unconstrained arrays.
21020 (Expand_Call): An indirect call through an access parameter of a
21021 protected operation is not a protected call.
21022 Add circuit to raise CE in Ada 2005 mode following call
21023 to Raise_Exception.
21024 (Register_DT_Entry): Do nothing if
21025 the run-time does not give support to abstract interfaces.
21026 (Freeze_Subprogram): In case of dispatching operations, do not generate
21027 code to register the operation in the dispatch table if the source
21028 is compiled with No_Dispatching_Calls.
21029 (Register_Predefined_DT_Entry): Generate code that calls the new
21030 run-time subprogram Set_Predefined_Prim_Op_Address instead of
21031 Set_Prim_Op_Address.
21033 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
21034 on array assignments if the right-hand side is a function call that has
21035 been inlined. Check is performed on the assignment in the block.
21036 (Process_Bounds): If bounds and range are overloaded, apply preference
21037 rule for root operations to disambiguate, and diagnose true ambiguity.
21038 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
21039 a tag-indeterminate right-hand side even when Expander_Active is True.
21040 Needed to ensure that dispatching calls to T'Input are allowed and
21041 get the tag of the target class-wide object.
21043 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
21044 an inherited primitive operation that already overrides several
21045 abstract interface primitives. For transitivity, the new entity must
21046 also override all the abstract interface primitives covered by the
21047 inherited overriden primitive.
21048 Emit warning if new entity differs from homograph in same scope only in
21049 that one has an access parameter and the other one has a parameter of
21050 a general access type with the same designated type, at the same
21051 position in the signature.
21052 (Make_Inequality_Operator): Use source locations of parameters and
21053 subtype marks from corresponding equality operator when creating the
21054 tree structure for the implicit declaration of "/=". This does not
21055 change anything in behaviour except that the decoration of the
21056 components of the subtree created for "/=" allows ASIS to get the
21057 string images of the corresponding identifiers.
21058 (Analyze_Return_Statement): Remove '!' in warning message.
21059 (Check_Statement_Sequence): Likewise.
21060 (Analyze_Subprogram_Body): For an access parameter whose designated type
21061 is an incomplete type imported through a limited_with clause, use the
21062 type of the corresponding formal in the body.
21063 (Check_Returns): Implicit return in No_Return procedure now raises
21064 Program_Error with a compile time warning, instead of beging illegal.
21065 (Has_Single_Return): Function returning unconstrained type cannot be
21066 inlined if expression in unique return statement is not an identifier.
21067 (Build_Body_To_Inline): It is possible to inline a function call that
21068 returns an unconstrained type if all return statements in the function
21069 return the same local variable. Subsidiary procedure Has_Single_Return
21070 verifies that the body conforms to this restriction.
21072 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
21073 same type, and one of them is of an anonymous access type, convert
21074 the other operand to it, so that this is a valid binary operation for
21076 (Resolve_Type_Conversion): Handle subtypes of protected types and
21077 task types when accessing to the corresponding record type.
21078 (Resolve_Allocator): Add '\' in 2-line warning message.
21079 Remove '!' in warning message.
21080 (Resolve_Call): Add '\' in 2-line warning message.
21081 (Valid_Conversion): Likewise.
21082 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
21083 resulting type may be an access type with an implicit dereference.
21084 Obtain the proper component from the designated type.
21085 (Make_Call_Into_Operator): Handle properly a call to predefined equality
21086 given by an expanded name with prefix Standard, when the operands are
21087 of an anonymous access type.
21088 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
21089 Explicit_Dereference and Resolve_Selected_Component, to verify that the
21090 prefix of the expression is not of an incomplete type. Allows full
21091 diagnoses of all semantic errors.
21092 (Resolve_Actuals): If the actual is an allocator whose directly
21093 designated type is a class-wide interface we build an anonymous
21094 access type to use it as the type of the allocator. Later, when
21095 the subprogram call is expanded, if the interface has a secondary
21096 dispatch table the expander will add a type conversion to force
21097 the displacement of the pointer.
21098 (Resolve_Call): If a function that returns an unconstrained type is
21099 marked Inlined_Always and inlined, the call will be inlined and does
21100 not require the creation of a transient scope.
21101 (Check_Direct_Boolean_Op): Removed
21102 (Resolve_Comparison_Op): Remove call to above
21103 (Resolve_Equality_Op): Remove call to above
21104 (Resolve_Logical_Op): Inline above, since this is only call.
21105 (Valid_Conversion): Handle properly conversions between arrays of
21106 convertible anonymous access types.
21109 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
21110 the literal in an unchecked conversion, because GCC 4.x needs a static
21111 value for a string bound.
21113 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21114 Hristian Kirtchev <kirtchev@adacore.com>
21116 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
21117 components of the corresponding record, take into account component
21118 definitions that are access definitions.
21119 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
21120 procedure is not considered a dispatching call and will be expanded
21123 2006-02-13 Javier Miranda <miranda@adacore.com>
21125 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
21126 controlling argument of the dispatching call is an abstract interface
21127 class-wide type then we use it directly.
21128 Check No_Dispatching_Calls restriction.
21129 (Default_Prim_Op_Position): Remove the code that looks for the last
21130 entity in the list of aliased subprograms. This code was wrong in
21132 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
21133 when the source is compiled with the No_Dispatching_Calls restriction.
21134 (Init_Predefined_Interface_Primitives): No need to inherit primitives
21135 if we are compiling with restriction No_Dispatching_Calls.
21136 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
21137 subprograms if we are compiling under No_Dispatching_Calls restriction.
21138 (Make_DT): Generate a dispatch table with a single dummy entry if
21139 we are compiling with the No_Dispatching_Calls restriction. In
21140 addition, in this case we don't generate code that calls to the
21141 following run-time subprograms: Set_Type_Kind, Inherit_DT.
21142 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
21143 of this subprogram if compiling with the No_Dispatching_Calls
21145 (Expand_Type_Conversion): Instead of using the actual parameter,
21146 the argument passed as parameter to the conversion function was
21147 erroneously referenced by the expander.
21148 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
21149 Set_Predefined_Primitive_Op_Address and Set_Signature.
21150 (Expand_Dispatching_Call): Generate call to
21151 Get_Predefined_Prim_Op_Address for predefined primitives.
21152 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
21153 predefined primitives.
21154 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
21155 primitives we reserve one dummy entry to ensure that the tag does not
21156 point to some memory that is associated with some other object. In
21157 addition, remove all the old code that generated the assignments
21158 associated with the signature of the dispatch table and replace them
21159 by a call to the new subprogram Set_Signature.
21160 (Set_All_DT_Position): Change the algorithm because now we have a
21161 separate dispatch table associated with predefined primitive operations.
21162 (Expand_Interface_Conversion): In case of non-static offset_to_top
21163 add explicit dereference to get access to the object after the call
21164 to displace the pointer to the object.
21165 (Expand_Interface_Thunk): Modify the generation of the actual used
21166 in the calls to the run-time function Offset_To_Top to fulfil its
21168 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
21170 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21172 * exp_dist.adb (Copy_Specification): For access parameters, copy
21173 Null_Exclusion flag, which will have been set for stream subprograms
21176 2006-02-13 Pascal Obry <obry@adacore.com>
21178 * expect.c (__gnat_expect_portable_execvp): New implementation. The
21179 previous implementation was using the C runtime spawnve routine but
21180 the corresponding wait was using directly the Win32 API. This was
21181 causing some times a lock when waiting for an event using
21182 WaitForSingleObject in __gnat_waitpid. This new implementation uses
21183 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
21184 API fixes this problem.
21186 2006-02-13 Robert Dewar <dewar@adacore.com>
21188 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
21191 2006-02-13 Thomas Quinot <quinot@adacore.com>
21193 * exp_pakd.ads: Fix typos in comments.
21195 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
21196 array reference that is an explicit dereference, mark the converted
21197 (packed) array reference as analyzed to prevent a forthcoming
21198 reanalysis from resetting its type to the original (non-packed) array
21201 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21202 Javier Miranda <miranda@adacore.com>
21203 Eric Botcazou <ebotcazou@adacore.com>
21205 * exp_util.ads, exp_util.adb (Find_Prim_Op,
21206 Is_Predefined_Primitive_Operation): When
21207 searching for the predefined equality operator, verify that operands
21208 have the same type.
21209 (Is_Predefined_Dispatching_Operation): Remove the code that looks
21210 for the last entity in the list of aliased subprograms. This code
21211 was wrong in case of renamings.
21212 (Set_Renamed_Subprogram): New procedure
21213 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
21214 Exp_Type constant computed when entering this subprogram.
21215 (Known_Null): New function
21216 (OK_To_Do_Constant_Replacement): New function
21217 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
21218 (Side_Effect_Free): An attribute reference 'Input is not free of
21219 side effect, unlike other attributes that are functions. (from code
21221 (Remove_Side_Effects): Expressions that involve packed arrays or records
21222 are copied at the point of reference, and therefore must be marked as
21223 renamings of objects.
21224 (Is_Predefined_Dispatching_Operation): Return false if the operation is
21225 not a dispatching operation.
21228 (Remove_Side_Effects): Lift enclosing type conversion nodes for
21229 elementary types in all cases.
21231 2006-02-13 Javier Miranda <miranda@adacore.com>
21233 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
21234 task types when accessing to the corresponding record type.
21235 Remove '!' in warning message.
21237 2006-02-13 Olivier Hainque <hainque@adacore.com>
21239 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
21240 to avoid useless and space inefficient overalignments on targets where
21241 Max_Alignment is larger than 16.
21243 2006-02-13 Pascal Obry <obry@adacore.com>
21245 * g-catiio.adb (Sec_Number): New type used to compute the number of
21246 seconds since 1-1-1970.
21247 (Image) [Natural]: The parameter was an Integer, as we can't deal with
21248 negative numbers (years, months...) it is better to have a Natural here.
21250 (Image) [Number]: Change parameter from Long_Integer to Number.
21251 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
21252 overflow for dates past year 2038.
21254 2006-02-13 Matthew Heaney <heaney@adacore.com>
21256 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
21259 2006-02-13 Arnaud Charlet <charlet@adacore.com>
21261 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
21263 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
21264 finalization can occur normally.
21266 2006-02-13 Vincent Celier <celier@adacore.com>
21268 * gnatcmd.adb (Rules_Switches): New table
21269 (Add_To_Rules_Switches): New procedure
21270 (GNATCmd): For command CHECK, put all options following "-rules" in the
21271 Rules_Switches table. Append these -rules switches after the -cargs
21274 2006-02-13 Robert Dewar <dewar@adacore.com>
21276 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
21277 These two cases were generating incorrect output, and if this unit
21278 was built with checks on, generated a discriminant mismatch constraint
21281 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21282 Robert Dewar <dewar@adacore.com>
21284 * lib-xref.adb (Get_Type_Reference): For a private type whose full
21285 view is an array type, indicate the component type as well, for
21286 navigation purposes.
21287 (Generate_Reference): Don't consider array ref on LHS to be a case
21288 of violating pragma Unreferenced.
21289 Do not give Ada 2005 warning except on real reference.
21291 2006-02-13 Vincent Celier <celier@adacore.com>
21293 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
21294 main source, add switch -mdebug-main=_ada_ so that the executable can
21295 be debugged by the standard VMS debugger.
21296 (Gnatmake): Set No_Main_Subprogram to True when there is no main
21297 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
21298 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
21299 of the last source, as the binding and linking phases are never
21301 Set all executable obsolete when rebuilding a library.
21303 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
21306 2006-02-13 Javier Miranda <miranda@adacore.com>
21309 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
21310 code to improve the error message reported when the program has
21311 declarations of abstract interface types and it is not compiled with
21312 the -gnat05 switch.
21313 (P_Access_Definition): Reorganize the code to improve the error
21314 message reported when the new Ada 2005 syntax for anonymous
21315 access types is used and the program is not compiled with the
21318 2006-02-13 Robert Dewar <dewar@adacore.com>
21320 * par-ch6.adb, style.ads, styleg.adb, styleg.ads, stylesw.adb,

21338 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
21339 unknown, use the location of the project to report the error.
21340 (When_No_Sources): New global variable
21341 (Report_No_Ada_Sources): New procedure
21342 (Check): New parameter When_No_Sources. Set value of global variable
21344 (Find_Sources): Call Report_No_Ada_Sources when appropriate
21345 (Get_Sources_From_File): Ditto
21346 (Warn_If_Not_Sources): Better warning messages indicating the unit name
21349 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
21350 Call Prj.Proc.Process with parameter When_No_Sources.
21352 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
21353 Call Recursive_Check with parameter When_No_Sources.
21354 (Recursive_Check): New parameter When_No_Sources. Call itself and
21355 Prj.Nmsc.Check with parameter When_No_Sources.
21356 (Process): New parameter When_No_Sources. Call Check with parameter
21358 (Copy_Package_Declarations): New procedure to copy renamed parameters
21359 and setting the location of the declared attributes to the location
21360 of the renamed package.

21366 * prj-makr.adb (Make): Preserve the comments from the original project
21368 When removing nodes (attributes Source_Dirs, Source_Files,
21369 Source_List_File and package Naming), save the comments and attach the
21370 saved comments to the newly created nodes.
21371 Do not add a with clause for the naming package if one already exists.
21373 2006-02-13 Javier Miranda <miranda@adacore.com>

21379 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
21380 aliased entities to look for the overriden abstract interface
21382 (Is_Interface_Subprogram): Complete documentation.
21383 (Check_Dispatching_Operation): Do not generate code to register the
21384 operation in the dispatch table if the source is compiled with
21385 restriction No_Dispatching_Calls.
21386 (Override_Dispatching_Operation): Check for illegal attempt to override
21387 No_Return procedure with procedure that is not No_Return
21388 (Check_Dispatching_Call): Suppress the check for an abstract operation
21389 when the original node of an actual is a tag-indeterminate attribute
21390 call, since the attribute, which must be 'Input, can never be abstract.
21391 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
21392 call to the Input attribute (even when rewritten).
21393 (Propagate_Tag): Augment comment to indicate the possibility of a call
21394 to an Input attribute.
21396 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
21397 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
21399 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
21400 No_Wide_Characters is no longer partition-wide
21401 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
21404 2006-02-13 Douglas Rupp <rupp@adacore.com>
21406 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
21408 2006-02-13 Javier Miranda <miranda@adacore.com>
21410 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
21411 handles default-initialized components to keep separate the management
21412 of this feature but also avoid the unrequired resolution and
21413 expansion of components that do not have partially initialized
21415 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
21416 (Check_Bounds): Likewise.
21417 (Check_Length): Likewise.
21419 2006-02-13 Javier Miranda <miranda@adacore.com>
21420 Ed Schonberg <schonberg@adacore.com>
21422 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
21423 abstract interface type call analyze_and_resolve to expand the type
21424 conversion into the corresponding displacement of the
21425 reference to the base of the object.
21426 (Eval_Attribute, case Width): For systems where IEEE extended precision
21427 is supported, the maximum exponent occupies 4 decimal digits.
21428 (Accessibility_Message): Add '\' in 2-line warning message.
21429 (Resolve_Attribute): Likewise.
21430 (case Attribute_Access): Significantly revise checks
21431 for illegal access-to-subprogram Access attributes to properly enforce
21432 the rules of 3.10.2(32/2).
21433 Diagnose use of current instance with an illegal attribute.
21435 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
21437 (Enclosing_Generic_Unit): New function to return a node's innermost
21438 enclosing generic declaration node.
21439 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
21440 (Type_Access_Level): The accessibility level of anonymous acccess types
21441 associated with discriminants is that of the current instance of the
21442 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
21443 (Compile_Time_Constraint_Error): Handle case of conditional expression.
21444 (Kill_Current_Values_For_Entity): New function
21445 (Enter_Name): Change formal type to Entity_Id
21447 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
21448 Ed Schonberg <schonberg@adacore.com>
21449 Gary Dismukes <dismukes@adacore.com>
21451 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
21452 Analyze_Compilation_Unit.
21453 Detect and warn on redundant with clauses detected in a package spec
21454 and/or body when -gnatwr is used.
21455 (Analyze_Context): Analyze config pragmas before other items
21456 (Install_Context_Items): Don't analyze config pragmas here
21457 (Install_Limited_Withed_Unit): Set limited entity of package in
21458 with_clause so that cross-reference information or warning messages on
21459 unused packages can be properly generated
21460 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
21461 has Error_Posted set. Prevent infinite loops in illegal programs.
21462 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
21463 to the point of the error test requiring the current unit to be private.
21464 This ensures that private with clauses are not exempted from the basic
21465 checking for being a descendant of the same library unit parent as a
21466 withed private descendant unit.
21467 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
21468 handle private with clauses properly, as well as to account for cases
21469 where the withed unit is a public descendant of a private ancestor
21470 (in which case the current unit must be a descendant of the private
21471 ancestor's parent). The spec comments were updated accordingly. Also,
21472 the old error message in this subprogram was replaced with error
21473 messages that mirror the errors tested and reported by
21474 Check_Private_Child_Unit.
21475 Parameter and variable names improved for readability.
21476 (Install_Limited_Context_Clauses): Remove test for a withed unit being
21477 private as the precondition for calling
21478 Check_Private_Limited_Withed_Unit since that subprogram has been
21479 revised to test public units as well as private units.

21484 Javier Miranda <miranda@adacore.com>
21486 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
21487 that Scope_Stack.First = 1.
21488 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21489 were not always properly handled previously.
21490 (Formal_Entity): Complete rewrite, to handle properly some complex case
21491 with multiple levels of parametrization by formal packages.
21492 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
21493 to the corresponding derived type declaration for proper semantics.
21495 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
21496 (Check_Component): Enforce restriction on components of
21497 unchecked_unions: a component in a variant cannot contain tasks or
21499 (Unchecked_Union): Allow nested variants and multiple discriminants, to
21501 Add pragma Ada_2005 (synonym for Ada_05)
21502 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21503 were not always properly handled previously.
21504 Document that pragma Propagate_Exceptions has no effect
21505 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
21506 (Set_Convention_From_Pragma): Check that if a convention is
21507 specified for a dispatching operation, then it must be
21508 consistent with the existing convention for the operation.
21509 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
21510 longer required to specify an vtable-ptr component in the record. For
21511 compatibility reasons we leave the support for the previous definition.
21512 (Analyze_Pragma, case No_Return): Allow multiple arguments
21514 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
21515 non-overrideen inherited operation with a controlling result as
21516 illegal only its implicit declaration comes from the derived type
21517 declaration of its result's type.
21518 (Check_Possible_Deferred_Completion): Relocate the object definition
21519 node of the subtype indication of a deferred constant completion rather
21520 than directly analyzing it. The analysis of the generated subtype will
21521 correctly decorate the GNAT tree.
21522 (Record_Type_Declaration): Check whether this is a declaration for a
21523 limited derived record before analyzing components.
21524 (Analyze_Component_Declaration): Diagnose record types not explicitly
21525 declared limited when a component has a limited type.
21526 (Build_Derived_Record_Type): Code reorganization to check if some of
21527 the inherited subprograms of a tagged type cover interface primitives.
21528 This check was missing in case of a full-type associated with a private
21530 (Constant_Redeclaration): Check that the subtypes of the partial and the
21531 full view of a constrained deferred constant statically match.
21532 (Mentions_T): A reference to the current type in an anonymous access
21533 component declaration must be an entity name.
21534 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
21535 class_wide type to refer to full type, not to the incomplete one.
21536 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
21537 available. Required to give support to the certified run-time.
21538 (Analyze_Component_Declaration): In case of anonymous access components
21539 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
21540 (Process_Discriminants): For an access discriminant, use the
21541 discriminant specification as the associated_node_for_itype, to
21542 simplify accessibility checks.
21544 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21545 Javier Miranda <miranda@adacore.com>
21547 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
21548 abstract interpretations on an operator, remove interpretations that
21549 yield Address or a type derived from it, if one of the operands is an
21551 (Try_Object_Operation.Try_Primitive_Operation,
21552 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
21553 location when creating the new reference to a primitive or class-wide
21554 operation as a part of rewriting a subprogram call.
21555 (Try_Primitive_Operations): If context requires a function, collect all
21556 interpretations after the first match, because there may be primitive
21557 operations of the same type with the same profile and different return
21558 types. From code reading.
21559 (Try_Primitive_Operation): Use the node kind to choose the proper
21560 operation when a function and a procedure have the same parameter
21562 (Complete_Object_Operation): If formal is an access parameter and prefix
21563 is an object, rewrite as an Access reference, to match signature of
21564 primitive operation.
21565 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21566 by an expanded name with prefix Standard, when the operands are of an
21567 anonymous access type.
21568 (Remove_Abstract_Operations): If the operation is abstract because it is
21569 inherited by a user-defined type derived from Address, remove it as
21570 well from the set of candidate interpretations of an overloaded node.
21571 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21574 2006-02-13 Bob Duff <duff@adacore.com>
21576 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21577 redundant use clauses.
21578 In particular, if the scope of two use clauses overlaps, but one is not
21579 entirely included in the other, we should not warn. This can happen
21580 with nested packages.
21581 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21582 reported errors. The bug was reported when the compiler was built
21583 with assertions enabled.
21584 (Find_Type): If the node is a 'Class reference and the prefix is a
21585 synchronized type without a corresponding record, return the type
21588 2006-02-13 Javier Miranda <miranda@adacore.com>
21590 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21591 if this is the full-declaration associated with a private declaration
21592 that implement interfaces, then the private type declaration must be
21594 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21595 as aliased. The use of the 'access attribute is not available for such
21596 object (for this purpose the object should be explicitly marked as
21597 aliased, but being an anonymous type this is not possible).
21599 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21600 Robert Dewar <dewar@adacore.com>
21602 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21603 compilation unit is an elaboration scope.
21604 (Add_Task_Proc): Add '\' in 2-line warning message.
21605 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21607 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21608 Javier Miranda <miranda@adacore.com>
21610 * sem_type.adb (Write_Overloads): Improve display of candidate
21612 (Add_One_Interp): Do not add to the list of interpretations aliased
21613 entities corresponding with an abstract interface type that is an
21614 immediate ancestor of a tagged type; otherwise we have a dummy
21615 conflict between this entity and the aliased entity.
21616 (Disambiguate): The predefined equality on universal_access is not
21617 usable if there is a user-defined equality with the proper signature,
21618 declared in the same declarative part as the designated type.
21619 (Find_Unique_Type): The universal_access equality operator defined under
21620 AI-230 does not cover pool specific access types.
21621 (Covers): If one of the types is a generic actual subtype, check whether
21622 it matches the partial view of the other type.
21624 2006-02-13 Thomas Quinot <quinot@adacore.com>
21626 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21627 line. This is necessary to allow In_Extended_Main_Unit to provide
21628 correct results for itypes while writing out expanded source.
21629 (Close_File): No need to update the source_index_table here since it's
21630 now done for each line.
21632 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21633 Robert Dewar <dewar@adacore.com>
21635 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21636 preserve the source unit where the itype is declared, and prevent a
21638 (Note_Implicit_Run_Time_Call): New procedure
21639 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
21642 * sprint.ads: Document use of $ for implicit run time routine call

21646 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21649 2006-02-13 Bob Duff <duff@adacore.com>
21651 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21652 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21653 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21654 raise Constraint_Error.
21656 * s-vallli.adb (Scan_Long_Long_Integer): Call
21657 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21658 do not scan leading blanks and sign twice.
21659 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21660 raise Constraint_Error.
21662 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21663 Scan_Long_Long_Unsigned): Split out most of the processing from
21664 Scan_Long_Long_Unsigned out into
21665 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21666 This prevents scanning leading blanks and sign twice.
21667 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21670 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21671 out most of the processing from Scan_Unsigned out into
21672 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21673 This prevents scanning leading blanks and sign twice.
21675 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21676 use with Modular'Value attribute.
21677 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

21877 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21878 link to the version that does nothing. This way the task termination

21880 because of an unhandled exception.
21882 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21883 handler because of an unhandled exception.
21885 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

21896 in charge of finalizing the global list for controlled objects.
21897 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21898 instead for handling run-time termination in a more flexible way.
21899 (Adafinal_NT): This new procedure will take care of finalizing the
21900 global list for controlled objects if needed, but no tasking
21903 * s-tarest.adb (Task_Lock): Do not try to lock again the
21904 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21905 some run-time operations.
21906 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21907 until all nested locks have been released.
21908 (Task_Wrapper): Call the fall-back task termination handler. It

21916 moved to the Common_ATCB record.
21917 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21918 Common_ATCB record.

21920 Common_ATCB record.
21922 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21923 Fall_Back_Handler, and Specific_Handler.

21926 defined in Ada.Task_Termination, to avoid circular dependencies.
21927 (Termination_Handler): Redefine this type here, alredy defined in
21928 Ada.Task_Termination, for avoiding circular dependencies.
21929 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21930 for storing task termination handlers. In addition,
21931 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21932 Common_ATCB because it is used by both the regular and the restricted
21934 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21935 Common_ATCB because it is used by both the regular and the restricted
21937 (Common_ATCB): Added a dynamic task analyzer field.

21945 using the soft links mechanism.
21946 (Task_Wrapper): added dynamic stack analysis.
21948 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21949 potentially blocking operations has been moved from
21950 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21951 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21952 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21953 this run-time check.
21955 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21956 of task termination procedure.
21957 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

21999 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
22000 to the specification because the frontend generates code that uses this
22002 (Set_Interface_Table): Add missing assertion.
22003 Update documentation describing the run-time structure.
22004 (Displace): New subprogram that displaces the pointer to the object
22005 to reference one of its secondary dispatch tables.
22006 (IW_Membership): Modified to use the new table of interfaces.
22007 (Inherit_TSD): Modified to use the new table of interfaces.
22008 (Register_Interface_Tag): Use the additional formal to fill the
22009 contents of the new table of interfaces.
22010 (Set_Interface_Table): New subprogram that stores in the TSD the

22025 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
22026 in all the calls to Expand_Interface_Thunk. Instead of referencing the
22027 record component containing the tag of the secondary dispatch table we
22028 have to use the Offset_To_Top run-time function to get this information;
22029 otherwise if the pointer to the base of the object has been displace
22030 we get a wrong value if we use the 'position attribute.
22032 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
22033 all the calls to Expand_Interface_Thunk.

22037 ensure that the interfaces implemented by the ancestors are placed
22038 at the header of the generated list.
22039 (Expand_Interface_Conversion): Handle the case in which the displacement
22040 associated with the interface conversion is not statically known. In
22041 this case we generate a call to the new run-time subprogram Displace.

22043 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
22044 Get_Tagged_Kind and Set_Tagged_Kind.

22068 RE_TK_Tagged, RE_TK_Task.
22070 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
22071 Init_Secondary_Tags_Internal to allow its use with interface types and
22072 also to generate the code for the new additional actual required
22073 by Set_Offset_To_Top.
22074 (Build_Init_Statements): In case of components associated with abstract
22075 interface types there is no need to generate a call to its IP.
22076 (Freeze_Record_Type): Generate Select Specific Data tables only for
22078 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
22079 the bodies and specifications of the predefined primitive operations
22080 dealing with dispatching selects and abort, 'Callable, 'Terminated only
22081 for concurrent types.

22086 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
22087 properly protected objects and attach handler in the case of the
22088 restricted profile.
22089 Move embeded package Select_Expansion_Utilities into a separate external

22101 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
22102 pointer initialization values. Make a SAVE_EXPR instead. Add comments
22103 about the use and expansion of SAVE_EXPRs in the various possible
22104 renaming handling cases.
22105 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
22106 abusing DECL_FCONTEXT.

22199 the iterator is quitting iteration on parent directory.
22201 2005-12-09 Javier Miranda <miranda@adacore.com>
22203 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
22204 and the assignment to a class-wide object, before the assignment we
22205 generate a run-time check to ensure that the tag of the Target is
22206 covered by the tag of the source.

22272 the size and positional fields of the new component.
22273 (Analyze_Component_Declaration): A limited component is
22274 legal within a protected type that implements an interface.
22275 (Collect_Interfaces): Do not add to the list the interfaces that
22276 are implemented by the ancestors.
22277 (Derived_Type_Declaration): If the parent of the full-view is an
22278 interface perform a transformation of the tree to ensure that it has
22279 the same parent than the partial-view. This simplifies the job of the
22280 expander in order to generate the correct object layout, and it is
22281 needed because the list of interfaces of the full-view can be given in
22283 (Process_Full_View): The parent of the full-view does not need to be
22284 a descendant of the parent of the partial view if both parents are
22286 (Analyze_Private_Extension_Declaration): If declaration has an explicit
22287 "limited" the parent must be a limited type.

22301 (Process_Full_View): Improve the check for the "no hidden interface"
22302 rule as defined by AI-396.

22361 available user-specified stream attributes on limited parameters to
22362 also test the type directly rather than only its underlying type (for
22363 Ada 95) and, in the case of Ada 2005, to check that the user-specified
22364 attributes are visible at the point of the subprogram declaration.
22365 For Ada 2005, the error message is modified to indicate that the
22366 type's stream attributes must be visible (again, only for -gnat05).

22398 types use the corresponding record type. This was not needed before
22399 the implementation of Ada 2005 synchronized types because
22400 concurrent types were never tagged types in Ada 95.

22551 can't handle that case.
22553 2005-11-17 Laurent Guerby <laurent@guerby.net>
22556 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

22625 may be platform-defined macros.
22626 For VxWorks, generate the OK and ERROR values.
22627 New constants giving the sizes of the components of C struct timeval.

22639 deal with different cases of static and dynamic elaboration checks (all
22640 checks does not count in the first case, but does in the second).

22646 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
22647 elementary types using the operator in standard. It is cleaner not to
22648 modify the programmers intent, especially in the case of floating-point.
22649 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
22650 it did not matter because we always rewrote a/=b to not(a=b).
22651 (Expand_Allocator_Expression): For an allocator expression whose nominal
22652 subtype is an unconstrained packed type, convert the expression to its
22653 actual constrained subtype.
22654 Implement warning for <= or >= where < or > not possible
22655 Fix to Vax_Float tests (too early in many routines, causing premature
22656 Vax_Float expansions.

22662 of pragma Suppress (All_Checks)
22663 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
22664 a string literal for precise control over warnings.
22665 Avoid raise of pragma in case of unrecognized pragma and just return
22668 * sem_prag.ads: Minor reformatting
22670 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
22671 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter

22673 Include -gnatwx as part of -gnatg (warn on redundant parens)
22674 Allow optional = after -gnatm
22675 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22676 longer sets Elaboration_Checks.
22677 Code to set warning mode moved to Sem_Warn
22678 so that it can be shared by pragma processing.
22680 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
22683 * s-taprop-solaris.adb:
22684 Change some <= to =, to avoid new warning

22692 * exp_vfpt.adb: Handle /= case
22693 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22800 from a fat or thin pointer type and a constrained object type.
22801 (annotate_value): Handle BIT_AND_EXPR.
22802 (annotate_rep): Don't restrict the back annotation of inherited
22803 components to the type_annotate_only case.
22804 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
22805 we are not defining the type.
22806 <E_Record_Type>: Likewise.
22807 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22808 to get advantage of the new maybe_stabilize_reference interface, to
22809 ensure that what we reference is indeed stabilized instead of relying
22810 on assumptions on what the stabilizer does.
22811 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22812 type imported through a limited_with clause, use its non-limited view.
22813 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22815 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22816 of #if sections + explicit comparisons of convention identifiers.
22817 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
22818 before early-returning for certain types when code generation is
22820 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
22821 nullification of gnu_expr we do for objects with address clause and
22822 that we are not defining.
22823 (elaborate_expression_1): Do not create constants when creating
22824 variables needed by the debug info: the dwarf2 writer considers that
22825 CONST_DECLs is used only to represent enumeration constants, and emits
22827 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22828 object with an address clause into an indirect reference, drop the
22829 initializing expression.
22831 (STACK_CHECK_BUILTIN): Delete.
22832 (STACK_CHECK_PROBE_INTERVAL): Likewise.

22839 related): For a prefix that is a dereference of a fat or thin pointer,
22840 if there is an actual subtype provided by the front-end, use that
22841 subtype to build an actual type with bounds template.
22842 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22843 is provided by the front-end, use that subtype to compute the size of
22844 the deallocated object.
22845 (gnat_to_gnu): When adding a statement into an elaboration procedure,
22846 check for a potential violation of a No_Elaboration_Code restriction.
22847 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22848 with extra arguments to control whether to recurse through non-values
22849 and to let the caller know if the stabilization has succeeded.
22850 (gnat_stabilize_reference): Now a simple wrapper around
22851 maybe_stabilize, for common uses without restriction on lvalues and
22852 without need to check for the success indication.
22853 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22854 pass false instead of 0 as the FORCE argument which is a bool.
22855 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22856 attached to a renaming pointer has been properly stabilized, as no such
22857 object is attached otherwise.
22858 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22859 function uses the "target pointer" return mechanism.
22860 Reinstate conversion of the actual to the type of the formal
22861 parameter before any other specific treatment based on the passing
22862 mechanism. This turns out to be necessary in order for PLACEHOLDER
22863 substitution to work properly when the latter type is unconstrained.
22865 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
22867 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22868 with extra arguments to control whether to recurse through non-values
22869 and to let the caller know if the stabilization has succeeded.
22871 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22872 static output of record constructor if all the components are constant.
22873 (gnat_build_constructor): For a record type, sort the list of field
22874 initializers in increasing bit position order.
22875 Factor common code to build a storage type for an unconstrained object
22876 from a fat or thin pointer type and a constrained object type.
22877 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22878 types variants, and process special cases of VIEW_CONVERT expressions
22879 as their NOP_EXPR counterpart to ensure we get to the
22880 CORRESPONDING_VARs associated with CONST_DECls.
22881 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22882 on the right-hand side.
22884 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
22886 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
22887 are converting back to its original type.
22888 (convert) <JM input>: Fallthrough regular conversion code instead of
22889 extracting the object if converting to a type variant.
22890 (create_var_decl): When a variable has an initializer requiring code
22891 generation and we are at the top level, check for a potential violation
22892 of a No_Elaboration_Code restriction.
22893 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22894 SIZE and SIZE_UNIT which we need for later back-annotations.

22896 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
22897 is an unchecked union.
22898 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22899 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22900 main variant, just replace the VIEW_CONVERT_EXPR.

23078 with an actual subtype so GIGI can make a correct size computation.
23079 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
23080 'Unrestricted_Access, if the designated type is an interface we
23081 add a type conversion to force the displacement of the pointer
23082 to the secondary dispatch table.
23083 Use Universal_Real instead of Long_Long_Float when we need a high
23084 precision float type for the generated code (prevents gratuitous
23085 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
23086 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
23087 'Terminated for task interface class-wide objects. Generate a call to
23088 the predefined dispatching routine used to retrieve the _task_id from
23089 a task corresponding record.

23114 if-statement that has elsif_parts, recompute the Current_Value node
23115 for any entity whose value is known from the condition of the first
23117 (Expand_N_Return_Statement): When returning a mutable record, convert
23118 the return value into its actual subtype in order to help the backend
23119 to return the actual size instead of the maximum. This is another

23139 a process handle, not need to convert.
23140 (__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.

23145 (Send_Signal): Release the process handle.
23147 2005-11-14 Robert Dewar <dewar@adacore.com>
23149 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

23169 attribute of the N_Free_Statement.
23170 Generate itype for classwide designated object in both cases of
23171 user-specified storage pool: specific and class-wide, not only in the
23173 Raise CE when trying to set a not null access type object to null.
23174 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
23175 an explicit loop, because freeze nodes make its position variable.

23451 leave it more clear.
23452 (Analyze_Type_Declaration): If type has previous incomplete tagged

23509 whose default is abstract because the object type itself is abstract.
23510 (Find_Type): If the type is incomplete and appears as the prefix of a
23511 'Class reference, it is tagged, and its list of primitive operations
23512 must be initialized properly.

23542 statement to inhibit warning.
23543 (Resolve_Unary_Op): Do not produce a warning when
23544 processing an expression of the form -(A mod B)
23545 Use Universal_Real instead of Long_Long_Float when we need a high

24525 Hristian Kirtchev <kirtchev@adacore.com>
24526 Javier Miranda <miranda@adacore.com>
24528 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
24529 from object notation, the original node is unanalyzed and carries no
24530 semantic information, so that accessiblity checks must be performed on
24531 the type of the actual itself.
24532 (Expand_N_Subprogram_Declaration): Change last actual parameter for
24533 compatibility with Build_Protected_Sub_Specification.
24534 (Check_Overriding_Inherited_Interfaces): Add suport to handle

24544 load comes from a Limited_With_Clause.
24546 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
24547 whether a potential circularity is harmless, because it includes units
24548 loaded through a limited_with clause. Extends previous treatment which
24549 did not handle properly arbitrary combinations of limited and
24550 non-limited clauses.
24552 2005-09-01 Nicolas Setton <setton@adacore.com>
24554 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types

24584 2005-09-01 Laurent Pautet <pautet@adacore.com>
24586 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
24587 position set is provided, we compute one in order to reduce the maximum
24588 length of the keys. This computation first selects a character
24589 position between 1 and the minimum length of the keys in order to
24590 avoid reducing one of the keys to an empty string.
24591 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24592 does not converge. The initialization procedure now comes with a
24593 maximum number of iterations such that when exceeded, an exception is
24594 raised in Compute. The user can initialize this ratio to another value
24596 Reformating and updated headers.
24598 2005-09-01 Javier Miranda <miranda@adacore.com>
24600 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24601 that given an entity T creates and returns an Itype that duplicates the
24602 contents of T. The returned Itype has the null-exclusion
24603 attribute set to True, and its Etype attribute references T
24604 to keep the association between the two entities.
24605 Update copyright notice
24607 * sem_aggr.adb (Check_Can_Never_Be_Null,
24608 Aggregate_Constraint_Checks, Resolve_Aggregate,

24640 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
24641 and N_Function_Specification.
24643 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
24644 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.

24700 Preset_Names for Name_Disp_Asynchronous_Select,
24701 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
24702 Name_Disp_Timed_Select.
24703 New pragma Debug_Policy
24705 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24707 Switch -gnata also sets Debug_Pragmas_Enabled
24709 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24710 handle an explicit -gnata when compiling predefined files.
24712 2005-09-01 Vincent Celier <celier@adacore.com>
24714 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24715 directories of projects that have no Ada sources.
24717 2005-09-01 Robert Dewar <dewar@adacore.com>
24719 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24720 (makes a difference for wide characters)
24722 * widechar.adb, widechar.ads:
24723 Add Wide_Char_Byte_Count feature to count chars vs bytes
24725 2005-09-01 Thomas Quinot <quinot@adacore.com>
24726 Ed Schonberg <schonberg@adacore.com>
24727 Robert Dewar <dewar@adacore.com>
24729 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24730 'Address attribute reference with an overloaded prefix, use the
24731 location of the prefix (not the location of the attribute reference) as
24732 the error location.
24733 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24734 a function renaming thereof, is a valid prefix for 'Size (where it is
24735 intepreted as a function call).
24736 (Statically_Denotes_Entity): New predicate to determine whether the
24737 prefix of an array attribute can be considered static.
24740 (Eval_Attr): Fix failure to evaluate Component_Size for

24750 2005-09-01 Javier Miranda <miranda@adacore.com>
24751 Ed Schonberg <schonberg@adacore.com>
24753 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24754 become local to the whole package.
24755 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24756 the package was already analyzed the new algorithm "replaces" the
24757 real entities by the shadow ones. This is required to ensure that
24758 the order of these entities in the homonym chains does not change;
24759 otherwise we can have undefined references at linking time because
24760 in case of conflicts the external name of the entities will have
24761 a suffix that depends on the order of the entities in the chain.
24762 (Remove_Limited_With_Clause): Complementary code that completes the
24763 new algorithm and replaces the shadow entities by the real ones.
24764 (Install_Limited_Withed_Unit): When unchaining entities before the
24765 installation of the shadow entities, only regular entities of the
24766 public part must be taken into account. This is required to
24767 keep this routine in synch with the work done by Remove_Limited_
24769 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24770 even if unit is analyzed, because the analysis of the unit is
24771 idempotent in any case, and the limited view of the unit may have to
24772 be installed for proper visibility.
24773 (Expand_Limited_With_Clause): Even if the unit in the implicit
24774 with_clause has been analyzed already, a limited view of the package
24775 must be built for the current context, if it does not exist yet.
24777 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24778 Javier Miranda <miranda@adacore.com>
24779 Gary Dismukes <dismukes@adacore.com>
24781 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24782 defining entity for the instance body, make a new defining identifier
24783 rather than copying the entity of the spec, to prevent accidental
24784 sharing of the entity list.
24785 (Check_Private_View): When exchanging views of private types, build the
24786 list of exchanged views as a stack, to ensure that on exit the exchanges
24787 are undone in the proper order.
24788 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24789 Restore the compilation environment in case of instantiation_error.
24790 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24791 for an anonymous access result.
24792 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24793 (Formal_Entity): Handle properly the case of a formal package that
24794 denotes a generic package renaming.
24796 2005-09-01 Thomas Quinot <quinot@adacore.com>
24798 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24799 clause if the array aggregate is surrounded by parentheses.

24802 Gary Dismukes <dismukes@adacore.com>
24803 Ed Schonberg <schonberg@adacore.com>
24804 Javier Miranda <miranda@adacore.com>
24806 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24808 to check if a type is Constrained in cases related to code generation
24809 (rather than semantic checking) since otherwise we do not generate
24810 similar code for mutable private types depending if their
24811 discriminants are visible or not.
24812 (Check_Abstract_Overriding): Do not complain about failure to override
24813 the primitive operations used in dispatching selects since they will
24814 always be overriden at the freeze point of the type.
24815 (Access_Definition): Separate out handling for resetting the scope
24816 of an anonymous access function result type. Retrieve the scope
24817 of the associated function rather than using Current_Scope, which
24818 does not have a consistent value (depends on whether we're in the
24819 middle of analyzing formal parameters). Add ??? comment about
24820 finding a cleaner way to handle the special cases of scope setting.
24821 (Process_Incomplete_Dependents): A protected operation is never a
24822 dispatching operation (only its wrapper may be).
24823 (Build_Derived_Record_Type): In case of tagged private types that
24824 implement interfaces add derivation of predefined primitive
24826 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24827 by two parameters that are used in case of derivation from abstract
24828 interface types: No_Predefined_Prims is used to avoid the derivation
24829 of predefined primitives from the interface, and Predefined
24830 Prims_Only is used to complete the derivation predefined primitives
24831 in case of private tagged types implementing interfaces.
24832 Fix typo in comments
24833 (Find_Interface_In_Descendant): Protect the frontend against
24834 wrong code with large circularity chains.
24835 (Is_Private_Overriding): Add support for entities overriding interface
24836 subprograms. The test failed because Entities associated with overriden
24837 interface subprograms are always marked as hidden (and used to build
24838 the secondary dispatch table); in this case the overriden entity is
24839 available through the field abstract_interface_alias (cf. override_
24840 dispatching_operation)
24841 (Access_Definition): Set the scope of the type to Current_Scope for the
24842 case of a function with an anonymous access result type.
24843 (Access_Subprogram_Declaration): Handle creation of the type entity for
24844 an access-to-function type with an anonymous access result.
24845 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24846 in handling for N_Access_Function_Definition.
24847 (Analyze_Subtype_Declaration): Modify the text of error message.
24848 (Derived_Type_Declaration): Modify the text of error message.
24849 (Process_Subtype): Modify the text of error message plus cleanup
24850 of one redundant error message.
24851 (Analyze_Component_Declaration): Code cleanup.
24852 (Analyze_Object_Declaration): Code cleanup.
24853 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24854 attribute in case of access types. Code cleanup.
24855 (Array_Type_Declaration): Code cleanup.
24856 (Process_Discriminants): Create the new null-excluding itype
24857 if required. Code cleanup.
24858 (Process_Subtype): Create the new null-excluding itype if
24859 required. Code cleanup.
24860 (Build_Derived_Record_Type): Code cleanup to avoid calling
24861 twice the subprogram derive_subprograms in case of private
24862 types that implement interfaces. In this particular case the
24863 subprogram Complete_Subprograms_Derivation already does the
24864 job associated with the second call.
24866 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24867 conversion to the full view when generating an operation for a
24868 discriminant whose type may currently be private.
24870 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24871 Javier Miranda <miranda@adacore.com>
24873 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24874 V (Obj.F), the rewriting does not involve the indexed component, but
24875 only the selected component itself.
24876 Do not apply the transformation if the analyzed node is an actual of a
24877 call to another subprogram.
24878 (Complete_Object_Operation): Retain the entity of the
24879 dispatching operation in the selector of the rewritten node. The
24880 entity will be used in the expansion of dispatching selects.
24881 (Analyze_One_Call): Improve location of the error message associated
24883 (Analyze_Selected_Component): No need to resolve prefix when it is a
24884 function call, resolution is done when parent node is resolved, as
24886 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24887 when attempting to resolve a call transformed from its object notation.
24888 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24889 of the argument list for each interpretation of the operation.
24890 (Try_Object_Operation): The designated type of an access parameter may
24891 be an incomplete type obtained through a limited_with clause, in which
24892 case the primitive operations of the type are retrieved from its full
24894 (Analyze_Call): If this is an indirect call, and the return type of the
24895 access_to_subprogram is incomplete, use its full view if available.

24898 Gary Dismukes <dismukes@adacore.com>
24900 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24901 access types the null-exclusion and access-to-constant attributes must
24903 (Analyze_Return_Statement): When the result type is an anonymous access
24904 type, apply a conversion of the return expression to the access type
24905 to ensure that appropriate accessibility checks are performed.
24906 (Analyze_Return_Type): For the case of an anonymous access result type,
24907 generate the Itype and set Is_Local_Anonymous_Access on the type.
24908 Add ??? placeholder for check to disallow returning a limited object
24909 in Ada 2005 unless it's an aggregate or a result of a function call.
24910 Change calls from Subtype_Mark to Result_Definition.
24911 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24912 Result_Definition in call to Make_Function_Specification.
24913 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24914 Set_Result_Definition.
24915 (Make_Inequality_Operator): Change formal Subtype_Mark to
24916 Result_Definition in call to Make_Function_Specification.
24917 (Process_Formals): Create the new null-excluding itype if required.
24918 (New_Overloaded_Entity): For an entity overriding an interface primitive
24919 check if the entity also covers other abstract subprograms in the same
24920 scope. This is required to handle the general case, that is, overriding
24921 other interface primitives and overriding abstract subprograms inherited
24922 from some abstract ancestor type.
24923 (New_Overloaded_Entity): For an overriding entity that comes from
24924 source, note the operation that it overrides.
24925 (Check_Conformance, Type_Conformant): Addition of one new formal
24926 to skip controlling formals in the analysis. This is used to
24927 handle overloading of abstract interfaces.
24928 (Base_Types_Match): Add missing case for types imported from
24929 limited-with clauses
24930 (New_Overloaded_Entity): Add barrier to protect the use of
24931 the "alias" attribute.
24933 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24935 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24936 verify that the procedure and the entry are mode conformant.
24937 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24938 as a different operator, which is often a cut-and-paste error.
24940 2005-09-01 Javier Miranda <miranda@adacore.com>
24941 Ed Schonberg <schonberg@adacore.com>
24943 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24944 used in controlling parameters exclude null because it is necessary to
24945 read the tag to dispatch, and null has no tag.
24946 (Override_Dispatching_Operation): If the previous operation is inherited
24947 from an interface, it becomes hidden and does not participate in later
24950 2005-09-01 Javier Miranda <miranda@adacore.com>
24951 Ed Schonberg <schonberg@adacore.com>
24952 Gary Dismukes <dismukes@adacore.com>
24954 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24955 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24956 the expander will generate the corresponding run-time check to evaluate
24958 (Resolve_Call): Check for legal type of procedure name or prefix that
24959 appears as a trigger in a triggering alternative.
24960 (Valid_Conversion): If expression is ambiguous and the context involves
24961 an extension of System, remove System.Address interpretations.
24962 (Resolve_Qualified_Expression): Reject the case of a specific-type
24963 qualification applied to a class-wide argument. Enhance comment
24964 to explain checking of Original_Node.
24965 (Resolve_Type_Conversion): The location of the error message was not
24966 general enough to handle the general case and hence it has been removed.
24967 In addition, this patch improves the text of the message.
24968 (Resolve_Type_Conversion): Add missing support for access to interface
24970 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24971 do not expand if the expression is the actual in a call, because proper
24972 expansion will take place when the call itself is expanded.
24973 (Resolve_Allocator): If the context is an unchecked conversion, the
24974 allocator inherits its storage pool, if any, from the target type of
24977 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24978 Javier Miranda <miranda@adacore.com>
24980 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24981 inherited interface operation that has an implementation, use the
24982 implementation to avoid spurious ambiguities.
24983 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24984 use the Corresponding_Record_Typ attribute to look for the interface
24985 because it is set by the expander (and hence it is not always
24986 available). For this reason we traverse the list of interfaces
24987 (available in the parent of the concurrent type).
24988 (Interface_Present_In_Ancestor): Handle entities from the limited view
24990 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24992 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24993 from the list of required components.
24994 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24995 primitive procedure of a limited interface with a controlling first
24997 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24999 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
25000 capture if it is generated in the second operand of a short-circuit
25002 Do not capture values for variables with address clauses.
25003 (Is_Object_Reference): Treat a function call as an object reference only
25004 if its type is not Standard_Void_Type.
25006 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25008 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
25009 to a variable that is statically known to be constant.

25026 Document new treatment of wide characters in max line length
25028 Remove -gnatL/-gnatZ switches, no longer used.
25029 Add note on pragmas Assertion_Policy and Debug_Policy in discussion

25791 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25792 longer protected objects. They have been replaced by lower-level
25793 suspension objects made up by a mutex and a condition variable (or
25794 their equivalent given a particular OS) plus some internal data to
25795 reflect the state of the suspension object.
25796 (Initialize, Finalize): Add this initialization procedure for
25797 Suspension_Object, which is a controlled type.
25798 (Finalize): Add the finalization procedure for Suspension_Object,
25799 which is a controlled type.
25801 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
25802 Ada.Synchronous_Task_Control because there is no longer a need for a
25803 VxWorks specific version of this package. Target dependencies
25804 has been moved to System.Task_Primitives.Operations.
25806 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
25808 (InitializeCriticalSection, EnterCriticalSection,
25809 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25810 pCriticalSection by an anonymous access type so that we avoid problems
25811 of accessibility to local objects.

25817 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
25818 set the environment task mask here.
25819 (Current_State): Add this function that returns the state of the
25821 (Set_False): Add this procedure that sets the state of the suspension
25823 (Set_True): Add this procedure that sets the state of the suspension
25824 object to True, releasing the task that was suspended, if any.
25825 (Suspend_Until_True): Add this procedure that blocks the calling task
25826 until the state of the object is True. Program_Error is raised if
25827 another task is already waiting on that suspension object.
25828 (Initialize): Add this procedure for initializing the suspension
25829 object. It initializes the mutex and the condition variable which are
25830 used for synchronization and queuing, and it sets the internal state
25832 (Finalize): Add this procedure for finalizing the suspension object,
25833 destroying the mutex and the condition variable.

25838 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
25839 which provides a low-level abstraction (using operating system
25840 primitives) for Ada.Synchronous_Task_Control.
25841 This object is made up by a mutex (for ensuring mutual exclusion), a
25842 condition variable (for queuing threads until the condition is
25843 signaled), a Boolean (State) indicating whether the object is open,
25844 and a Boolean (Waiting) reflecting whether there is a task already
25845 suspended on this object.

25862 System.Parameters.No_Abort is True.
25864 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
25865 is no longer done in the body of s-taprop

26257 access to subprograms must be recursive.
26258 (Is_Unchecked_Conversion): Improve the test that recognizes
26259 instantiations of Unchecked_Conversion, and allows them in bodies that
26260 are to be inlined by the front-end. When the body comes from an

26284 Prevent the special checks for conversions of access discriminants in
26285 the case where the discriminant belongs to a nonlimited type, since
26286 such discriminants have their accessibility level defined in the same
26287 way as a normal component of an anonymous access type.
26288 (Resolve_Allocator): When an allocator's designated type is a class-wide
26289 type, check that the accessibility level of type given in the
26290 allocator's expression or subtype indication is not statically deeper

26310 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
26311 check on possible violation of restriction No_Direct_Boolean_Operators

27318 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

27321 error messages if expansion has been disabled due to previous
27322 (unrelated) errors).
27324 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
27325 is disabled, the entity denoted by the argument is the access type

27337 denotes a type in the class.
27338 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
27339 of Name_Generic_Dispatching_Constructor.
27341 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

27357 generic formal subprogram association for an abstract formal subprogram.
27358 Check that the attribute is a primitive stream attribute (and not
27359 a class-wide stream attribute) and then rewrite the attribute name
27360 as the name of the appropriate compiler-generated stream primitive.

27372 itype whose parent is controlled and not yet frozen, do not create a
27373 freeze node for the itype if expansion is disabled.
27375 2005-03-29 Vincent Celier <celier@adacore.com>
27377 * make.adb (Gnatmake): Don't fail if the main project file is declared
27378 as having no Ada sources. Do not display message "no sources to

28033 * a-stunau.ads, a-stunau.adb:
28034 Change interface to allow efficient (and correct) implementation

28080 Update documentation on Must_Be_Byte_Aligned for new spec
28082 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
28083 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
28084 uses of the Access_Disp_Table attribute to reference the first dispatch
28085 table associated with a tagged type. As
28086 part of the implementation of abstract interface types,
28087 Access_Disp_Table has been redefined to contain a list of dispatch
28088 tables (rather than a single dispatch table).
28089 Similarly, upgrade all the references to Tag_Component by the
28090 new attribute First_Tag_Component.
28091 (Find_Inherited_TSS): Moved to exp_tss.

28099 Bit packed array ops are only called if operands are known to be
28101 (Component_Equality): When returning an N_Raise_Program_Error statement,
28102 ensure that its Etype is set to Empty to avoid confusing GIGI (which
28103 expects that only expressions have a bona fide type).
28104 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
28105 determine the amount of data to be copied.
28107 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
28108 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):

28135 (Task_Body_Procedure): Removed.
28136 (Set_Task_Body_Procedure): Removed.
28137 These subprogram have been removed because the attribute
28138 Task_Body_Procedure has been moved to the corresponding task type
28139 or task subtype entity to leave a field free to store the list
28140 of interfaces implemented by a task (for AI-345)
28141 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
28142 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
28143 expression flag Do_Range_Check

28156 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
28159 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
28160 attribute Task_Body_Procedure rather than the old semantic field that
28161 was available in the task_type_declaration node.
28163 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
28164 interface type definitions.
28165 (P_Formal_Derived_Type_Definition): Modified to handle the list of
28168 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
28169 task type declaration.

28171 protected type declaration.
28173 2005-03-15 Doug Rupp <rupp@adacore.com>

28203 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
28204 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
28205 expression to the type of the object when the object is constant.
28206 Reverse defer_debug_incomplete_list before traversing it, so that trees
28207 are processed in the order at which they were added to the list. This
28208 order is important when using the stabs debug format.
28209 If we are deferring the output of debug information, also defer this
28210 output for a function return type.
28211 When adding fields to a record, prevent emitting debug information
28212 for incomplete records, emit the information only when the record is
28214 (components_to_record): New parameter defer_debug.

28222 unconstrained arrays properly.
28224 * gigi.h (write_record_type_debug_info): New function.
28225 Convert to use ANSI-style prototypes. Remove unused
28226 declarations for emit_stack_check, elab_all_gnat and

28236 converting to an unchecked union type.
28238 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
28239 replace the N_Freeze_Entity with a null statement.
28241 * freeze.adb (Freeze_Expression): If the freeze nodes are generated

28247 within records; allow them to have freeze nodes if their base types
28250 * exp_util.adb (Remove_Side_Effects): Properly test for
28251 Expansion_Delayed and handle case when it's inside an
28252 N_Qualified_Expression.
28254 * sem_ch3.adb (Derived_Type_Declaration): New predicate
28255 Comes_From_Generic, to recognize accurately that the parent type in a
28256 derived type declaration can be traced back to a formal type, because
28257 it is one or is derived from one, or because its completion is derived
28259 (Constrain_Component_Type): If component comes from source and has no
28260 explicit constraint, no need to constrain in in a subtype of the
28262 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
28263 Minor change to propagate Is_Ada_2005 flag
28265 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
28266 Expansion_Delayed is False.
28267 (assoc_to_constructor): Ignore fields that have a
28268 Corresponding_Discriminant.
28269 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
28270 function returns "by target", dereference the target pointer using the
28271 type of the actual return value.
28272 <all>: Be prepared for a null gnu_result.
28273 (processed_inline_subprograms): Check flag_really_no_inline

28286 System.Pack_nn unit.
28288 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
28290 Needed now that we do some processing for IN parameters as well. This
28291 may well fix some unrelated errors.
28292 (Expand_Call): Handle case of unaligned objects (in particular those
28293 that come from packed arrays).
28294 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
28295 renamed entity is an inherited operation, re-expand the call using the
28296 original operation, which is the one to call.
28297 Detect attempt to inline parameterless recursive subprogram.
28298 (Represented_As_Scalar): Fix to work properly with private types
28299 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
28300 accurate estimate. Yields True in far fewer cases than before,
28301 improving the quality of code that depends on this test.
28303 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
28304 over both visible and private declarations to remove them from tree,
28305 and mark subprograms declared in package as eliminated, to prevent
28306 spurious use in subsequent compilation of generic units in the context.
28308 * exp_util.ads: Minor cleanup in variable names
28310 * sem_eval.ads, sem_eval.adb: Minor reformatting
28311 (Compile_Time_Known_Bounds): New function

28315 * exp_ch7.adb (Convert_View): Use base types of underlying types when
28316 determining whether an unchecked conversion is needed for the argument
28317 of an initialization call.
28319 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28321 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
28322 that appears in the instantiation rather than the internal subtype
28323 generated in the wrapper package, to avoid anomalies in gigi when the
28324 target is derived from a private type whose full view is an access type.
28326 2005-03-15 Robert Dewar <dewar@adacore.com>
28328 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
28330 Add documentation to replace the use of this flag
28331 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
28334 2005-03-15 Thomas Quinot <quinot@adacore.com>
28336 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
28337 here from exp_attr so it can be shared between exp_attr and exp_dist.
28338 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
28339 all TSS names, not a subset thereof, and the previous name introduced
28340 an unnecessarily confusion that a distinction might exist between
28341 "OK" TSS names and some "not OK" TSS names.
28343 2005-03-15 Doug Rupp <rupp@adacore.com>
28345 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
28348 2005-03-15 Pascal Obry <obry@adacore.com>
28349 Eric Botcazou <ebotcazou@adacore.com>
28353 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
28354 when IN_RTS. This is to work around a bootstrap path problem.

28365 Arnaud Charlet <charlet@adacore.com>
28368 This change works fine when gnatlib is built from the gcc directory,
28369 but does not work when using the libada Makefile, since GCC_FOR_TARGET
28370 is not passed to ada/Makefile.in, so more work is needed by a
28371 Makefile/configure expert.
28373 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
28374 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
28375 Setup gnatlink switch -M for x86_64 linux, as it is already setup
28377 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
28378 Run ranlib on libgccprefix.a
28379 Define PREFIX_OBJS for Darwin, to build libgccprefix.
28380 (ADA_INCLUDE_SRCS): Split Ada packages.
28382 2005-03-15 Robert Dewar <dewar@adacore.com>
28384 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
28386 * impunit.adb: Add GNAT.UTF_32
28388 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
28390 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
28391 now uses GNAT.UTF_32).
28393 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
28394 capabilities for categorizing characters using Unicode categories
28396 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28398 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
28399 instantiation that has been rewritten as a package body, retrieve spec
28400 to generate proper name for implicit_with_clause.
28401 (Install_Parents): Recognize a parent that is an instantiation but has
28402 been rewritten as a package declaration during analysis.
28404 2005-03-15 Javier Miranda <miranda@adacore.com>
28405 Ed Schonberg <schonberg@adacore.com>
28407 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
28408 parameter reported some error we immediately return. This improves the
28409 behaviour of the frontend in case of errors.
28410 (Install_Parent, Remove_Parent): Introduce new flag
28411 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
28412 ancestor of a generic child unit, when the child is being instantiated.
28413 (Inline_Instance_Body): If we are compiling the private
28414 part or the body of a child unit, restore the proper visibility of the
28415 parents after compiling the instance body.
28417 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28418 Javier Miranda <miranda@adacore.com>
28421 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
28422 of a private type, in which case it is underlying_type that denotes
28423 the proper task. Also modified to use the new entity attribute
28424 that is directly available in the task type and task subtype entities
28425 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
28426 arrays when other dimensions than the first are constrained by
28427 discriminants of an enclosing record.
28428 (Insert_Explicit_Dereference): If the prefix is an indexed component or
28429 a combination of indexed and selected components, find ultimate entity
28430 and generate the appropriate reference for it, to suppress spurious
28432 (Note_Possible_Modification): If an entity name has no entity, return.
28433 (Is_Variable): A function call never denotes a variable.
28434 (Requires_Transient_Scope): For record types, recurse only on
28435 components, not on internal subtypes that may have been generated for
28436 constrained components.
28438 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28440 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
28441 Eliminated as candidates for resolution. Both efficient, and avoids
28442 anomalies with operators declared in deleted code.
28443 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
28444 expansion is disabled (as when compiling a generic) to prevent spurious
28445 warnings on prefixes of selected components.
28447 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28449 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
28450 attached to a list before checking whether it appears in the private
28451 declarations of the current package.
28452 (Make_Inequality_Operator): Insert declaration in proper declarative
28453 list rather than just setting the Parent field, so that
28454 Is_Private_Declaration can handle it properly.
28456 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28458 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
28459 a renaming a body, check that the renamed subprogram in not intrinsic.
28460 (Find_Direct_Name): If several use_visible entities hide
28461 each other, and the context is a predefined file compiled through
28462 rtsfind, keep only the entity that comes from a predefined file.
28464 2005-03-15 Geert Bosch <bosch@adacore.com>
28466 * s-fatgen.adb (Valid): Extend special exceptions to account for long
28467 long float padding to also cover AMD64 and IA64.

28838 (Attribute_Renaming): Replace use of Corresponding_Spec with
28839 Corresponding_ Formal_Spec and simplify condition.
28840 (Use_One_Package): Check that scope of homonym of identifier is defined,
28841 before checking whether it is a wrapper package.
28842 Add support for wide wide character type
28844 * sem_eval.adb: Add support for wide wide character type.

28851 "not in" for test of N_Formal_Subprogram_Declaration (which is now a
28853 (Unit_Declaration_Node): Ditto.
28854 (Is_Variable_Prefix): For the case of an indexed component whose prefix
28855 has a packed array type, the prefix has been rewritten into a type
28856 conversion. Determine variable-ness from the converted expression.
28857 Handle wide wide character cases.

28861 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28862 Remove ["0A"] from comment, since it can look like a line terminator.
28863 Currently we don't permit this, but this is under discussion by the
28864 ARG, and it is easy enough to use a different example.
28866 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28867 handling UTF-32 encoding for wide wide character.

28883 Rcheck subprograms.
28885 * checks.adb (Check_Null_Not_Allowed): Replace the error message on
28886 wrong null-exclusion value by a warning message.
28887 (Enable_Range_Check): Do range check if the prefix is an
28888 explicit dereference whose designated object is an unconstrained array.

28907 defined for subprogram renaming declarations. When set, the field
28908 indicates the defining entity of a corresponding formal subprogram
28909 when the renaming corresponds to a formal subprogram association in an
28911 (Set_Corresponding_Formal_Spec): New procedure to return
28912 Corresponding_Formal_Spec field.
28913 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration
28914 (which is now a subtype).
28915 Char_Literal_Value field is now a Uint
28917 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
28918 pointer to the base of the dispatch table.
28919 Minor changes to comments.

28925 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28926 describing the new layout.
28927 (Dispatch_Table): The expander computes the actual array size, allocates
28928 the Dispatch_Table record accordingly, and generates code that displaces
28929 the base of the record after the Typeinfo_Ptr component. The access to
28930 these components is done by means of local functions.
28931 (Offset_To_Top): New function.
28932 (Typeinfo_Ptr): New function.
28933 (Get_TSD): Modified to access the new position of the TSD.
28934 (Set_TSD): Modified to save the TSD in its new position.

28944 N_Formal_Subtype_Declaration (which is now a subtype).
28945 (Analyze_Formal_Subprogram): Add handling for
28946 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28947 dispatching, setting the controlling status of the formal parameters
28948 and result, and issuing an error if there is no controlling type for
28949 the formal subprogram.
28950 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28951 which is an unclean use of that field, we set the new field
28952 Corresponding_Formal_Spec to make the formal subprogram available to
28953 processing in Analyze_Subprogram_Declaration.
28954 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28955 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
28956 Constrained, so that it is is does not statically match its anonymous

28960 abstract formal subprograms in error check for functions returning
28961 abstract types. Set scope of new designator for
28962 a parameterless subprogram, so that it is available when checking the
28963 body for nested subprograms, before full analysis of said body.
28964 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28965 subprogram only if inner one comes from source.
28966 (Analyze_Function_Call): If the call is given in object notation, the
28967 analysis of the name rewrites the node and analyzes it with the proper
28968 argument list. After analyzing the name, if the call has been rewritten
28969 and the result type is set, no further analysis is needed.
28970 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28971 mark in function specification, in a context where the formals are
28972 visible and hide outer homographs.
28974 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28975 as the tagged type for the cases of abstract formal subprograms and
28976 renamings of those. Clean up spec comments.
28977 (Check_Dispatching_Context): Add error message to indicate "abstract
28978 procedure", covering the case of a call to a formal abstract procedure
28979 that has statically tagged operands.
28980 (Check_Dispatching_Call): Check for the case of an actual given by
28981 a tag-indeterminate function call whose type is an ancestor of the
28982 containing call's associated tagged type. This situation can occur
28983 for inherited primitives with function defaults. In this case we
28984 use the tagged type's tag directly as the controlling argument for
28986 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28988 * sprint.adb (Sprint_Node_Actual): Split
28989 N_Formal_Subprogram_Declaration into two alternatives for the new
28990 cases N_Formal_Abstract_Subprogram_Declaration and

29065 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
29066 on the field if Pragma Component_Alignment (Storage_Unit).
29067 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
29068 side-effects as if it were a constant; also make SAVE_EXPR to protect
29070 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
29072 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
29073 (components_to_record): Test it.

29086 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29088 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
29089 component of an array of arrays in an assignment context, and the
29090 aggregate has component associations that require sliding on
29091 assignment, force reanalysis of the aggregate to generate a temporary
29092 before the assignment.
29093 (Must_Slide): Make global to the package, for use in Gen_Assign.
29095 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29097 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
29098 unchecked union with no inferable discriminants, return a
29099 Raise_Program_Error node, rather than inserting it at the point the
29101 (Expand_Record_Equality, Component_Equality): Handle properly the case
29102 where some subcomponent is an unchecked union whose generated equality
29103 code raises program error.

29111 Arnaud Charlet <charlet@adacore.com>
29113 * init.c (__gnat_initialize): Add a new parameter eh which contains the
29114 address of the exception registration. The Win32 version of this
29115 routine calls __gnat_install_SEH_handler() to initialize the SEH
29116 (Structured Exception Handling) handler.
29117 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
29118 SEH (Structured Exception Handling) now.
29119 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
29120 (__gnat_initialize for ppc-vxworks): Adjust comments and the
29121 preprocessor condition protecting the call to the extra eh setup
29122 subprogram, which is only available for the ppc target.
29123 (__gnat_clear_exception_count): replaced reference to
29124 variable taskIdCurrent by call to taskIdSelf(), cleaner.
29126 * seh_init.c: New file.
29128 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
29129 (GNATBIND_OBJS): Idem.
29131 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
29132 routine takes a new parameter (a pointer to the exception registration
29133 for the SEH (Structured Exception Handling) support.
29135 * raise.h: (__gnat_install_SEH_handler): New prototype.
29136 Update copyright notice.
29138 * s-tassta.adb (Task_Wrapper): Declare the exception registration
29139 record and initialize it by calling __gnat_install_SEH_handler.

29168 2005-02-09 Vincent Celier <celier@adacore.com>
29170 * prj-makr.adb (Process_Directory): Put file name in canonical case
29171 before matching against the patterns.
29172 If gnatname has been invoked as <prefix>-gnatname
29173 then invoke the compiler as <prefix>-gcc, not just "gcc".
29175 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29177 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
29178 with expansion disabled. The actual subtype is needed among other
29179 places when the selected component appears in the context of a loop
29180 bound, and denotes a packed array.
29181 (Operator_Check): Always use the first subtype in the
29182 error message, to avoid the appearance of internal base types.
29183 (Transform_Object_Operation): Copy each actual in full
29184 to the parameter associations of the constructed call, rather than
29185 using the shallow copy mechanism of New_Copy_List. This ensures that
29186 the chaining of named associations is done properly.
29187 (Complete_Object_Operation): Rewrite node, rather than
29188 replacing it, so that we can trace back to the original selected
29191 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
29192 and calls that use object notation, if the called function is not
29193 declared in a withed unit, place the elaboration constraint on the
29194 unit in the context that makes the function accessible.
29195 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
29196 imposes an elaboration constraint between two packages.
29198 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29200 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
29201 views of a private type after handling its private dependents, to
29202 maintain proper stack discipline between entry and exit from the

29218 recursion warnings when compiled with -gnatdm.
29220 2005-02-09 Robert Dewar <dewar@adacore.com>
29222 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
29223 Slight fix to documentation of -gnaty with no parameters
29225 * xr_tabls.ads: Add ??? comment for missing overall comment
29227 * xsinfo.adb: Make default file name be sinfo.h, since this is what
29228 we now use by default.
29230 * xsnames.adb: Adjust end of file test to look for five space followed
29231 by '#' instead of six spaces. The format of xsnames.adb was modified
29232 in the last update.
29234 * a-numeri.ads: Add reference to AI-388 for greek letter pi
29237 * clean.adb: Minor reformatting.
29239 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
29240 gnatname.adb: Minor reformatting
29241 Add 2005 to copyright output when utility is run
29243 * csets.adb: Eliminate obsolete comment
29245 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
29248 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
29250 2005-02-09 Sergey Rybin <rybin@adacore.com>
29252 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
29253 the difference between compact and incompact layout and add the record
29254 representation clause to the example illustrating different layouts.
29255 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
29256 component clauses").
29258 2005-02-09 Florian Villoing <villoing@adacore.com>
29260 * gnat_ugn.texi: Fix typos.
29261 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
29263 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
29264 in the generated documentation.
29266 2005-02-09 Arnaud Charlet <charlet@adacore.com>
29268 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

29299 from the VxWorks kernel) that is needed for getting the active
29300 priority of the different tasks.
29302 * s-atacco.ads, s-atacco.adb (Nothing): Remove this dummy procedure.
29303 Use a pragma Elaborate_Body in the spec file instead.
29304 Noticed by code reading.
29306 2005-02-09 Thomas Quinot <quinot@adacore.com>
29308 * exp_util.ads: Minor correction in comment.
29310 2005-02-09 Arnaud Charlet <charlet@adacore.com>
29312 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
29313 since this procedure is now too complex to be worth inlining.

29563 is to check if two function signatures for a call-site and a callee are
29564 compatible enough for the call to be valid. The underlying purpose is
29565 to check if a call to a mapped builtin is using the right interface.
29566 The current code actually does not check antyhing - this a placeholder

29618 structure of GARLIC and PolyORB RPC receivers.
29619 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
29621 Simplify elaboration code for RCI packages.
29623 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver

29733 note that it applies to obsolete GNAT features, which was previously
29734 omitted. Second we contrast the behavior with that of the new
29735 Ada 2005 AI-368 restriction No_Obsolescent_Features.
29736 Preliminary rewriting of GNAT & libraries chapter in order to take
29737 into account default project locations & new project manager

29969 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
29970 fields claimed addressable still have to be bitfields. Use
29971 value_factor_p instead of a raw binop construction to check for the
29972 position's alignment.

29979 Ed Schonberg <schonberg@adacore.com>
29981 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29982 with an implicit dereference as its prefix, use
29983 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29985 prefix is generated, if appropriate.
29987 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29988 dereference is rewritten to an explicit one, generate a reference to
29989 the entity denoted by its prefix using the original prefix node, so

29991 access value, if appropriate.
29993 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29994 emitting 'assigned but never read' warning on a variable on the basis

30010 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
30011 subprogram which is Imported with convention Intrinsic if an
30012 External_Name argument is specified.
30013 (Process_Import_Or_Interface): Properly diagnose link name argument.

30039 PolyORB_Support.Build_Stub_Type): New subrograms containing the
30040 PCS-specific part of Add_Stub_Type.

30070 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
30071 and the Has_Pragma_Unreferenced flag for each formal before analyzing
30072 the body, to ensure that warnings are properly emitted for each accept
30073 statement of a given task entry.

30101 (Remove_Next): Same cleanup
30103 2004-12-07 Thomas Quinot <quinot@adacore.com>
30105 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
30106 used to record an implicit dereference as a read operation on its
30107 prefix when operating under -gnatc. Necessary to avoid spurious
30108 'variable assigned but never read' warnings in that mode.
30109 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
30110 is a non-overloaded implicit dereference, call the above subprogram to
30111 ensure proper recording of references.
30113 2004-12-07 Gary Dismukes <dismukes@adacore.com>
30115 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

30163 2004-12-07 Vincent Celier <celier@adacore.com>
30165 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
30166 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
30167 and -eit to -ept. Added qualifier
30168 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
30170 2004-11-27 Andreas Schwab <schwab@suse.de>
30172 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
30174 2004-11-25 Arnaud Charlet <charlet@adacore.com>
30176 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
30177 internal implementation unit GNAT.Sockets.Thin,
30178 as their usage for sockets is non-portable (using the read and write
30179 functions from the system runtime library is fine on UNIX but won't
30180 work under Windows).

30236 new Others_Value and All_Others_Value objects.
30237 (struct attrib): Rename "arg" component as "args", since GCC expects a
30238 list of arguments in there.
30240 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
30241 corresponding objects exported by a-exexpr, instead of hardcoded dummy
30244 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
30245 others_decl and all_others_decl instead of hardcoded dummy addresses
30246 to represent "others" and "all others" choices, which is cleaner and
30247 more flexible with respect to the possible eh pointer encoding policies.
30249 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
30250 (process_attributes): Account for the naming change of the "args"
30251 attribute list entry component.
30253 * decl.c (build_attr_list): Rename into prepend_attributes to allow
30254 cumulating attributes for different entities into a single list.
30255 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
30256 attributes for the current entity and propagate first subtype
30257 attributes to other subtypes.
30258 <E_Procedure>: Attribute arguments are attr->args and not
30259 attr->arg any more.
30260 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
30261 argument provided, as this is what GCC expects. Use NULL_TREE instead
30264 2004-11-18 Robert Dewar <dewar@adacore.com>
30266 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

30298 (Insert_Partition_Check): Remove fossile code.
30299 (First_RCI_Subprogram_Id): Document this constant.
30300 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
30302 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
30303 replaced with calls to Get_Library_Unit_Name_String. Previously there
30304 were several instances of the same code in different locations in the
30305 compiler; this checkin completes the replacement of all of these
30306 instances with calls to a common subprogram.
30307 Minor reformatting.

30317 if the context comes from source.
30319 * snames.ads (PCS_Names): New subtype corresponding to names of
30320 supported implementations of the Partition Communication Subsystem
30321 (PCS) (i.e. the runtime library support modules for the distributed
30324 2004-11-18 Robert Dewar <dewar@adacore.com>
30325 Ed Schonberg <schonberg@adacore.com>
30327 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
30328 (Has_Rep_Pragma): New function
30329 (Has_Attribute_Definition_Clause): New function
30330 (Record_Rep_Pragma): Moved here from sem_ch13.adb
30331 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
30333 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
30335 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
30336 (Expand_Pragma_Psect_Object): New procedure
30337 These procedures contain the revised and cleaned up processing for
30338 these two pragmas. This processing was formerly in Sem_Prag, but
30339 is more appropriately moved here. The cleanup involves making sure
30340 that the pragmas are properly attached to the tree, and that no
30341 nodes are improperly shared.
30343 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
30344 pragmas to Exp_Prag, which is more appropriate.
30345 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
30346 check for duplicates Remove use of Is_Psected flag, no longer needed.
30347 Use new Make_String_Literal function with string.
30349 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
30350 that are functions return universal values, that have to be converted
30351 to the context type.
30352 Use new Make_String_Literal function with string.
30353 (Get_Stream_Convert_Pragma): New function, replaces the use of
30354 Get_Rep_Pragma, which had to be kludged to work in this case.
30356 * freeze.adb: Use new Has_Rep_Pragma function
30358 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
30359 function with string.
30360 Use new Has_Rep_Pragma function.
30362 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
30365 2004-11-18 Robert Dewar <dewar@adacore.com>
30367 * errout.ads, errout.adb: (First_Sloc): New function
30369 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
30370 check (-gnatyx) instead of being included as a redundant construct
30373 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
30374 Style_Check_Order_Subprograms.
30376 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
30377 stylesw.adb: Add Style_Check_Xtra_Parens
30379 * usage.adb: Add line for -gnatyx (check extra parens)
30381 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
30383 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30384 Robert Dewar <dewar@adacore.com>
30386 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
30387 discriminant of a constrained subtype, analyze the copy of the
30388 corresponding constraint, because in some cases it may be only
30389 partially analyzed.
30390 Removes long-lived ??? comments.
30392 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
30393 handled controlled or secondary-stack expressions within the
30394 iteration_scheme of a loop.
30396 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
30397 bounds that may contain functions calls, to prevent memory leaks when
30398 the bound contains a call to a function that uses the secondary stack.
30399 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
30400 generate temporaries for loop bounds that might contain function calls
30401 that require secondary stack and/or finalization actions.
30403 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
30404 selected component and the selector is overloadable (not just a
30405 function) treat as function call, Analyze_Call will disambiguate if
30407 (Analyze_Selected_Component): Do not generate an actual subtype for the
30408 selected component if expansion is disabled. The actual subtype is only
30409 needed for constraint checks.
30410 (Analyze_Allocator): If restriction No_Streams is set, then do
30411 not permit objects to be declared of a stream type, or of a
30412 composite type containing a stream.
30414 * restrict.ads: Remove the a-stream entry from Unit_Array, since
30415 No_Streams no longer prohibits with'ing this package.
30417 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
30418 discriminants, but the parent base has unknown discriminants, there is
30419 no discriminant constraint to inherit. Such a discrepancy can arise
30420 when the actual for a formal type with unknown discriminants is a
30421 similar private type whose full view has discriminants.
30422 (Analyze_Object_Declaration): If restriction No_Streams is set, then
30423 do not permit objects to be declared of a stream type, or of a
30424 composite type containing a stream.
30426 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30428 * exp_dbug.ads: Update documentation to reflect simpler encoding for
30429 protected operations.
30431 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
30432 generated name, it complicates decoding in gdb and hinders debugging
30433 of protected operations.
30434 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
30435 flag for the protected entry barrier function.
30436 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
30437 flag for the protected entry function.
30439 2004-11-18 Nicolas Setton <setton@adacore.com>
30441 * expect.c: Define __unix__ when __APPLE__ is defined.
30443 * Makefile.in: Inform the value of the variable GMEM_LIB in the
30444 Darwin-specific section.
30446 * lang-specs.h: Change the placement of the %1 marker.
30447 Works around the fact that gcc adds -fPIC by default under Darwin.
30449 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30451 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
30452 type of the object with the packed array type, set the Analyzed flag
30453 on the object if it is an entity or simple indexed component, to avoid
30454 spurious type errors.
30456 2004-11-18 Gary Dismukes <dismukes@adacore.com>
30458 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
30459 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
30460 separate line from the version message.
30462 2004-11-18 Ed Falis <falis@adacore.com>
30464 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
30466 (init_float): Eliminate initialization of floating point status for
30467 AE653. The instructions have no effect for vThreads.
30469 2004-11-18 Vincent Celier <celier@adacore.com>
30471 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
30472 gnatbind is invoked with -shared.
30474 2004-11-18 Jose Ruiz <ruiz@adacore.com>
30476 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
30477 for Detect_Blocking which is redundant with the check done within the
30478 procedure Protected_Single_Entry_Call.
30479 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
30480 Detect_Blocking which is redundant with the check done within the
30481 procedure Protected_Single_Entry_Call.
30483 2004-11-18 Vincent Celier <celier@adacore.com>
30485 * makegpr.adb (Compile): Put the compiling switches (in package
30486 Compiler and on the command line) immediately after "-c", instead of
30487 at the end of the command line invocation of the compiler, when
30488 compiling a non-Ada file.
30489 (Build_Global_Archive): When there is no need to rebuild the archive,
30490 set Global_Archive_Exists, so that the archive is passed to the linker
30493 2004-11-18 Robert Dewar <dewar@adacore.com>
30494 Sergey Rybin <rybin@adacore.com>
30497 Remove extra paren check from list of checks for redundant constructs
30498 Add documentation of new -gnatyx style check (check extra parens)
30499 Remove paragraph about gnatelim debug options.
30501 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
30502 objects rather than forbidding dependencies on the package Ada.Streams.
30504 * sinfo.ads: Add ??? note that we should document pragmas passed to
30507 * g-expect.ads: Fix a few typos in the comments.
30509 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
30511 * misc.c (gnat_handle_option): Use %< and %> for quoting in
30514 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
30516 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
30518 2004-11-07 Andreas Schwab <schwab@suse.de>
30520 * Makefile.in (install-gnatlib): Remove spurious hyphen.
30522 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
30525 * Makefile.in (darwin): Set soext to .dylib.
30527 2004-10-26 Vincent Celier <celier@gnat.com>
30528 Thomas Quinot <quinot@act-europe.fr>
30530 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
30531 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
30532 there is no use of GNAT.Sockets.Constants.
30533 Remove remaining pragma Import for C_Write
30534 Remove C_Read and C_Write from internal implementation unit
30535 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30536 the read and write functions from the system runtime library is fine
30537 on UNIX but won't work under Windows).
30539 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30540 (Check_Selector): Use C_Recv instead of C_Read.
30541 Selectors are the GNAT.Sockets abstraction to perform a select()
30542 call on a set of descriptors. To allow abortion of an ongoing
30543 select operation, some data is written to a dedicated socket that
30544 is always monitored.
30545 Under Windows, the write and read library functions cannot operate
30546 on sockets, so we need to use send and recv instead, which is portable
30547 across all supported platforms.
30549 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
30550 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
30551 (using the read and write functions from the system runtime library is
30552 fine on UNIX but won't work under Windows).
30554 2004-10-26 Nicolas Setton <setton@act-europe.fr>
30556 * mlib-tgt-darwin.adb: New file.
30558 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30559 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30560 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
30561 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
30564 * Makefile.in: Add support for building shared libraries under Darwin.
30565 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
30566 the low level EH init subprogram to be called from __gnat_initialize.
30568 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
30569 indicates which options to pass to the archive indexer.
30571 * mlib-utl.adb: Add support for calling ranlib with additional
30572 options. This is needed for instance under Mac OS X.
30573 (Ranlib_Options): New global variable, used to store the potential
30574 options to pass to ranlib.
30575 (Ar): Use Ranlib_Options when spawning ranlib.
30576 (Initialize): Set the value of ranlib option.
30578 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30580 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30581 instead of 8K, to reflect the real potential needs for stack-checking
30584 2004-10-26 Pascal Obry <obry@gnat.com>
30586 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30588 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30589 Windows only the initial thread stack size can be set so it is good to
30590 start we a low stack size.
30591 The OS will adjust the size as needed.
30593 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30594 Nicolas Setton <setton@act-europe.fr>
30596 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30597 "__unix__" instead of "unix".
30598 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30599 sections were just mistakenly ignored. The former is
30600 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30601 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30602 of hpux. This prevents an unwanted definition of the symbol
30603 convert_addresses in adaint.o.
30605 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30607 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30608 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30610 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30612 * a-filico.ads, a-filico.adb: fix incorrect header.
30614 2004-10-26 Javier Miranda <miranda@gnat.com>
30616 * a-ststio.ads: Fix typo in identifier
30618 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30620 * sem_ch4.adb: Minor reformatting.
30622 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30624 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30625 enabled, check the result of unary and binary operations when the
30626 expression is the right-hand side of an assignment.
30628 2004-10-26 Vincent Celier <celier@gnat.com>
30630 * clean.adb (Delete): Do not output warnings when in quiet output and
30631 not in verbose mode.
30632 (Force_Deletions): New Boolean flag, defaulted to False
30633 (Delete): Only delete a file if it is writable, and when
30634 Force_Deletions is True.
30635 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30636 (Usage): Line for new switch -f
30637 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30640 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30642 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30643 JM type only if its size matches that of the wrapper. When a size is
30644 prescribed and the field is not aliased, remove the wrapper of a JM
30645 type only if the size is not greater than that of the packed array.
30646 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30649 2004-10-26 Geert Bosch <bosch@gnat.com>
30651 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30652 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30653 (Pred): Implement in terms of Succ.
30655 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30657 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30658 unchecked conversion is safe for in-place use if the expression of the
30659 conversion is safe.
30660 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30661 be expandable in place even if the aggregate does not come from source.
30662 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30663 designated object of an allocator in place, rather than building it
30664 first on the stack. The previous scheme forces a full copy of the array,
30665 and may be altogether unsusable if the size of the array is too large
30666 for stack allocation.
30668 2004-10-26 Robert Dewar <dewar@gnat.com>
30670 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30671 compares if the component is atomic.
30673 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30674 array assignment if the component type is atomic.
30676 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30677 Eric Botcazou <ebotcazou@act-europe.fr>
30679 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30680 is aliased and is a by_reference type, do not pass by copy.
30681 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30682 detect whether the call is in the right side of an assignment or
30683 the expression of an object declaration. Recurse on component
30684 association within aggregates.
30685 Call it in the condition that determines whether the temporary is
30686 necessary for correct stack-checking.
30688 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30690 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30691 RACW_Type, used in the PolyORB version.
30692 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30693 version and the GARLIC version.
30695 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30696 Rename RCI_Info to RCI_Locator for better consistency between the
30697 GARLIC and PolyORB versions of the distributed systems annex.
30698 (DSA_Implementation_Name): This enumeration lists the possible
30699 implementations of the Partition Communication Subsystem for the
30700 Distributed Systems Annex (DSA). The three available implementations
30701 are the dummy stub implementation (No_DSA), and two versions based on
30702 two different distribution runtime libraries: GARLIC and PolyORB. Both
30703 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30705 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30708 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30709 between the GARLIC and PolyORB versions of the distributed systems
30711 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30713 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30715 * gnat1drv.adb: Suppress calling the back end when
30716 Frontend_Layout_On_Target is true.
30718 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30720 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30721 Set_Read_Only): New subprograms.
30722 These new routines allow the user to set or unset the Owner execute
30723 and Owner write permission flags on a file.
30725 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30726 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30728 2004-10-26 Matthew Gingell <gingell@gnat.com>
30730 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30732 2004-10-26 Pascal Obry <obry@gnat.com>
30734 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30735 memory before the faulting page we properly test the process read
30736 access for this address using appropriate Win32 routine.
30737 (HPUX sections): guard with "__hpux__" instead of "hpux".
30739 2004-10-26 Robert Dewar <dewar@gnat.com>
30741 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30742 entry parameter if pragma Unreferenced set, since we do not properly
30743 handle the case of multiple parameters.
30745 2004-10-26 Vincent Celier <celier@gnat.com>
30747 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30748 (Ada_Objects_Path.Add): For a library project, add to the object path
30749 the library directory only if there is no object directory or if the
30750 library directory contains ALI files.
30751 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30753 2004-10-26 Vincent Celier <celier@gnat.com>
30755 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30756 extension of library projects.
30758 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30759 path defaults to ".:<prefix>/lib/gnat".
30760 (Parse): For an extending all project, allow direct import of a project
30761 that is virtually extended.
30763 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30764 the specified name is directly imported, return its ID. Otherwise, if
30765 an extension of this project is imported, return the ID of the
30768 2004-10-26 Robert Dewar <dewar@gnat.com>
30770 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30771 (Sub3): New procedure, used by Scaled_Divide
30772 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30773 correct more than one instance of failure to propagate carries
30775 (Double_Divide): Handle overflow case of largest negative number
30776 divided by minus one.
30778 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30779 the case of a quotient value out of range.
30782 2004-10-26 Robert Dewar <dewar@gnat.com>
30784 * s-bitops.adb (Bit_Eq): Remove redundant check.
30786 * s-bitops.ads: Minor comment updates
30787 Change some occurrences of Address to System.Address
30789 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30791 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30793 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30794 accessibility check to prefix that is a protected operation.
30796 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30798 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30799 empty, post message on stub.
30801 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30802 Javier Miranda <miranda@gnat.com>
30804 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30805 current instance appears within a unit that is directly in the context
30807 Used to determine whether the body of the instance should be analyzed
30808 immediately after its spec, to make its subprogram bodies available
30809 for front-end inlining.
30810 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30811 constraint is not allowed on the component type (AARM 12.5.3(3))
30813 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30815 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30816 'Storage_Pool): enhance, document & limit detection of non-sharable
30819 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30821 * s-pooglo.ads: Add more documentation now that this pool is properly
30824 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30826 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30827 or protected type with discriminants, do not constrain the
30828 corresponding record type if the subtype declaration has no
30829 discriminant constraints. This can be the case in source code, or in
30830 the subtype declaration created to rename an actual type within an
30833 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30835 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30836 different kind of stub (possibly wrong name for file), do not check
30838 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30839 includes call to some function that returns an unconstrained type, do
30842 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30844 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30845 appear in the code for the main unit. Dependencies among units in the
30846 context of the main unit are established when those other units are
30847 compiled. Otherwise spurious elaboration constraints can generate
30848 incorrect elaboration circularities.
30850 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30851 Ed Schonberg <schonberg@gnat.com>
30853 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30854 subprogram is called with a parameter that is not an object name. This
30855 situation arises for some cases of illegal code, which is diagnosed
30856 later, and in this case it is wrong to call Is_Aliased, as that might
30857 cause a compiler crash.
30858 (Explain_Limited_Type): Refine previous fix to include
30859 inherited components of derived types, to provide complete information.
30861 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30862 is the prival for a protected object.
30863 It is necessary to mark this entity as a variable, in addition to
30864 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30865 modified to avoid checking the Aliased flag on entities that are not
30866 objects. (Checking that flag for non-objects is erroneous and could
30867 lead to a compiler crash).
30869 2004-10-26 Robert Dewar <dewar@gnat.com>
30871 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30872 X_Frac = 0.5, then we know that the number X must be positive.
30873 (Succ): Remove the same redundant test, and also fix the primary test
30874 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30876 (Decompose): Add fuller comments to spec
30878 2004-10-26 Pascal Obry <obry@gnat.com>
30880 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30881 validity (process must have read access). Set to 0 in all other cases.
30882 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30883 violation on Win32.
30884 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30885 segmentation violation.
30887 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30889 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30890 whose type is a constructed subtype of an aliased object with an
30891 unconstrained nominal subtype, convert the actual to the constructed
30892 subtype before taking its address.
30894 2004-10-26 Vincent Celier <celier@gnat.com>
30896 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30897 (Is_Path_Name_Case_Sensitive): New function
30899 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30900 (Base_Name, Simple_Name, Current_Directory, Compose,
30901 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30904 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30905 Vasiliy Fofanov <fofanov@act-europe.fr>
30906 Vincent Celier <celier@gnat.com>
30908 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30909 "memory management issues" section and document some of the useful
30910 memory pools provided as part of the GNAT library.
30911 Remove "virtual" from declaration of A::method2 in
30912 the simple example of Ada/C++ mixed system.
30913 Library Projects may be virtually extended: their virtual extensions
30914 are not Library Projects.
30915 Added section on extending project hierarchies.
30917 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30919 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30921 (__gnat_portable_spawn): Remove const.
30923 * mingw32.h (MAXPATHLEN): Check for previous definition.
30925 2004-10-17 Matthias Klose <doko@debian.org>
30927 * gnatvsn.ads: Set gnat library version to 4.0.
30929 2004-10-05 Vincent Celier <celier@gnat.com>
30931 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30933 2004-10-04 Laurent Guerby <laurent@guerby.net>
30936 * Makefile.in: Define and use RANLIB_FLAGS.
30938 2004-10-04 Pascal Obry <obry@gnat.com>
30940 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30941 other x86 platforms).
30943 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30945 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30946 in general and triggers stack alignment adjustment for thread entry
30947 points on targets where this is necessary.
30949 2004-10-04 Bernard Banner <banner@gnat.com>
30952 * Makefile.in: Add section for powerpc linux
30953 Add variant i-vxwork-x86.ads
30955 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30957 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30959 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30960 table registration calls when need be. Ensures no reference to the crt
30961 ctors symbol are issued in the SJLJ case, which avoids possible
30962 undefined symbol errors in the case of modules to be statically linked
30965 2004-10-04 Javier Miranda <miranda@gnat.com>
30967 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30968 in-line the code corresponding to subprogram Analyze_Actuals. In
30969 addition, analyze the actuals only in case of subprogram call.
30971 2004-10-04 Ed Falis <falis@gnat.com>
30973 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30975 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30977 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30978 in the documentation.
30980 2004-10-04 Robert Dewar <dewar@gnat.com>
30982 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30984 (Analyze_Block_Statement): Add circuitry to detect following dead code
30985 (Check_Unreachable_Code): Handle case of block exit
30987 2004-10-04 Robert Dewar <dewar@gnat.com>
30989 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30990 (XMatchD): Avoid warning for Logic_Error call
30992 2004-10-04 Robert Dewar <dewar@gnat.com>
30994 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30995 consider expressions buried within a procedure actual to be an actual.
30996 This caused some blowups with uses of packed slices within a procedure
30999 2004-10-04 Robert Dewar <dewar@gnat.com>
31001 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
31002 longer need to be initialized to zero.
31003 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
31004 initialized to zero.
31006 * checks.adb (Expr_Known_Valid): Packed arrays are now always
31007 considered valid, even if the representation is modular. That's correct
31008 now that we no longer initialize packed modular arrays to zero.
31010 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
31011 suffixes. These are now documented as the only cases in which the
31012 debugger ignores outer records.
31013 Previously, the spec allowed arbitrary suffixes for this purpose.
31014 Change name of LJM to JM for packed array pad records
31015 Create separate section on packed array handling, and add a whole new
31016 set of comments to this section describing the situation with packed
31017 modular types and justification requirements depending on endianness.
31019 2004-10-04 Robert Dewar <dewar@gnat.com>
31021 * a-except.adb: Add a comment for last change
31023 * einfo.ads: Minor spelling correction in comment
31025 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
31027 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
31030 * sem_util.ads: Minor comment update
31032 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31034 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
31035 Inline_Always when in Configurable_Run_Time mode.
31037 * sem_prag.adb (Process_Convention): If entity is an inherited
31038 subprogram, apply convention to parent subprogram if in same scope.
31039 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
31040 when in Configurable_Run_Time mode.
31042 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31044 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
31045 class_wide type after component list has been inherited.
31047 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31049 * sem_ch12.adb (Check_Generic_Actuals): New predicate
31050 Denotes_Previous_Actual, to handle properly the case of a private
31051 actual that is also the component type of a subsequent array actual.
31052 The visibility status of the first actual is not affected when the
31053 second is installed.
31054 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
31055 make fully recursive the treatment of formals of packages declared
31057 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
31058 the above on exit from an instantiation.
31059 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
31060 current instantiation which is now complete.
31061 (Analyze_Package_Instantiation): No instantiated body is needed if the
31062 main unit is generic. Efficient, and avoid anomalies when a instance
31063 appears in a package accessed through rtsfind.
31065 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31067 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
31068 do not generate a declaration for a temporary if the call is part of a
31069 library-level instantiation.
31071 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31073 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
31074 searching for a limited component to flag.
31076 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
31077 expansion of Input, to account for the fact that the implicit call
31078 generated by the attribute reference must freeze the user-defined
31079 stream subprogram. This is only relevant to 'Input, because it can
31080 appear in an object declaration, prior to the body of the subprogram.
31082 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
31083 expansion can proceed and further errors uncovered.
31084 (Minor clean up): Fix cases of using | instead of \ for continuation
31087 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
31089 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
31091 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
31092 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
31093 Use gcc_assert and gcc_unreachable.
31095 * decl.c (gnat_to_gnu_entity, case object): Check and process a
31096 specified alignment before validating size.
31097 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
31098 stripped-down declaration for the type of the inner field when making
31101 * utils.c (finish_record_type): Do not compute the size in units
31102 incrementally. Instead compute it once for the rep clause case.
31103 Use gcc_assert and gcc_unreachable.
31105 2004-10-04 Vincent Celier <celier@gnat.com>
31107 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
31109 (Is_Valid_Path_Name): Take '/' as a directory separator.
31111 2004-10-04 Vincent Celier <celier@gnat.com>
31113 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
31114 (Extended_Project) only if Extended_Project is defined, to avoid
31116 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
31118 (Parse_Single_Project): Ditto.
31120 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
31121 Add_To_Project_Path for virtual projects.
31123 2004-10-04 Vincent Celier <celier@gnat.com>
31125 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
31126 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
31127 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
31128 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
31129 parameter Options_2.
31131 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
31132 Build_Dynamic_Library with an empty Options_2.
31134 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
31137 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
31138 directory separator, if any.
31139 (Gprmake): Do not allow mains on the command line for library projects.
31140 Do not attempt to link when the project is a library project.
31141 (Library_Opts): New table to store Library_Options.
31142 (Build_Library): If Library_Options is specified, pass these options
31143 when building a shared library.
31145 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
31147 * s-tposen.adb (Service_Entry): The object must be always unlocked at
31148 the end of this procedure now that the unlock operation was inserted
31151 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
31153 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
31154 corresponding to the Preallocated_Stacks flags in System.
31155 (Get_Target_Parameters): Including the processing for
31156 Preallocated_Stacks.
31158 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
31159 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,
31160 system-freebsd-x86.ads, system-lynxos-ppc.ads, system-lynxos-x86.ads,

31163 system-solaris-x86.ads, system-irix-o32.ads, system-irix-n32.ads,
31164 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
31165 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
31166 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
31167 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
31168 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
31169 used to signal whether the compiler creates the required stacks and
31170 descriptors for the different tasks (when True) or it is done by the
31171 underlying operating system at run time (when False).
31172 It is initially set to False in all targets.
31174 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
31175 if it is supported by the target.
31176 (Make_Task_Create_Call): Pass the stack address if it has been
31177 previously created. Otherwise pass a Null_Address.
31179 * snames.adb: Add _stack.
31181 * snames.ads: Add Name_uStack. Required to allow the expander to
31182 statically allocated task stacks.
31184 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
31185 Stack_Address argument.
31186 Check that its value is equal to Null_Address because this target does
31187 not support the static stack allocation.
31189 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
31191 * usage.adb: Change "pragma inline" to "pragma Inline" in information
31194 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
31196 * exp_dist.adb: Split declaration of asynchronous flag out of
31197 Add_RACW_Read_Attribute.
31198 Minor reformatting for better alignment with PolyORB version.
31199 Store the entity for the asynchronous flag of an RACW, rather than the
31200 expression, in the asynchronous flags table. This will allow this flag
31201 to be used in other subprograms beside Add_RACW_Read_Attribute.
31203 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
31205 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
31206 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
31207 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
31208 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
31209 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
31210 sockets constant MSG_NOSIGNAL (Linux-specific).
31211 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
31212 all Send operations.
31213 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
31214 from trigerring SIGPIPE.
31215 Rename components to avoid clash with Ada 2005 possible reserved
31217 (Check_Selector): When the select system call returns with an error
31218 condition, propagate Socket_Error to the caller.
31220 2004-10-01 Jan Hubicka <jh@suse.cz>
31222 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
31224 2004-09-23 Robert Dewar <dewar@gnat.com>
31227 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
31228 instead do this at freeze time (we won't do it if there is an address
31230 Change "pragma inline" to "pragma Inline" in information and error
31232 Minor reformatting.
31234 * freeze.adb (Check_Address_Clause): Remove previous change, not the
31235 right way of doing things after all.
31236 (Freeze_Entity): For object, set Is_Public for imported entities
31237 unless there is an address clause present.
31239 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
31241 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
31242 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
31243 ensures proper handling of types with rep clauses, which might have
31244 their TYPE_SIZE set already.
31246 2004-09-21 Robert Dewar <dewar@gnat.com>
31248 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
31249 packed array types in both little- and big-endian cases. This change
31250 ensures that we no longer count on the unused bits being initialized
31251 for such types (and in particular ensures that equality testing will
31252 only read the relevant bits).
31253 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
31254 These changes mean that we no longer need to initialize small packed
31256 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
31257 optimization to an LJM field as to its parent field.
31259 * ada-tree.h, trans.c, utils.c, utils2.c:
31260 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
31262 2004-09-20 Jan Hubicka <jh@suse.cz>
31264 * utils.c (gnat_finalize): Remove.
31265 (end_subprog_body): Directly call cgraph_finalize_function;
31266 do not lower the nested functions.
31268 2004-09-20 Robert Dewar <dewar@gnat.com>
31271 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
31272 if an address clause is present, since that means that the Import
31275 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
31277 * 5tsystem.ads: Removed, no longer used.
31279 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
31280 Zack Weinberg <zack@codesourcery.com>
31282 * ada-tree.def: Use tree_code_class enumeration constants
31283 instead of code letters.
31284 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
31285 Update for new tree-class enumeration constants.
31287 2004-09-17 Vincent Celier <celier@gnat.com>
31289 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private
31290 capabilities of the general project manager.
31292 2004-09-09 Vincent Celier <celier@gnat.com>
31294 * a-direct.ads: Add pragma Ada_05
31295 (Directory_Entry_Type): Give default value to component Kind to avoid
31296 not initialized warnings.
31298 * a-direct.adb (Current_Directory): Remove directory separator at the
31300 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
31301 an existing directory.
31302 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
31303 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
31304 Convert the result to File_Size.
31306 * prj.ads: (Project_Error): New exception

31320 exception Prj.Prj_Error may be raised in case of problem.
31321 (Add_Unknown_Package, Add_Attribute): Moved to new child package
31323 (Attrs, Package_Attributes): Table instantiations moved from the body to
31324 the private part to be accessible from Prj.Attr.PM body.

31384 raise Program_Error if called from a protected operation.
31386 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
31387 the protected action nesting level.
31388 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
31389 protected action nesting level.
31390 (Unlock): When pragma Detect_Blocking is active decrease the protected
31391 action nesting level.
31393 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
31394 Protected_Action_Nesting.
31396 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
31397 Common_ATCB record. It contains the dynamic level of protected action
31398 nesting for each task. It is needed for checking whether potentially
31399 blocking operations are called from protected operations.
31400 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
31401 Detect_Blocking is active or not in the partition.
31403 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

31437 contains the required machinery for handling that.
31439 * sem_util.ads: Change comment associated to procedure
31440 Check_Potentially_Blocking_Operation.
31441 This procedure does not insert a call for raising the exception because
31442 that is currently done by the run time.
31444 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
31446 * init.c: Add the global variable __gl_detect_blocking that indicates
31447 whether pragma Detect_Blocking is active (1) or not (0). Needed for
31448 making the pragma available at run time.
31449 (__gnat_set_globals): Pass and update the detect_blocking parameter.

31452 pragma Detect_Blocking is active.
31454 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
31456 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
31457 DB is found in the ali file. Any unit compiled with pragma
31458 Detect_Blocking active forces its effect in the whole partition.
31460 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
31461 Detect_Blocking is active and delay is called from a protected
31464 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
31465 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
31466 Detect_Blocking is active (0 otherwise).
31467 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
31468 as Detect_Blocking parameter if pragma Detect_Blocking is active (0

31477 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
31478 (Register_Receiving_Stub): Add Subp_Info formal parameter.
31479 Update API in placeholder implemetation of s-parint to reflect changes
31480 in distribution runtime library.
31482 * sem_ch3.adb (Expand_Derived_Record): Rename to
31483 Expand_Record_Extension.
31485 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
31486 primitive operations of potentially distributed object types that have
31487 non-controlling anonymous access formals.
31489 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
31491 New implementation of expansion for remote access-to-subprogram types,
31492 based on the RACW infrastructure.
31493 This version of sem_dist is compatible with PolyORB/DSA as well as
31496 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
31497 Asynchrronous that applies to a remote access-to-subprogram type, mark
31498 the underlying RACW type as asynchronous.
31500 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
31501 __gnat_using_gnu_linker to 1.
31503 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
31504 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

31510 * exp_ch3.adb (Expand_Derived_Record): Rename to
31511 Expand_Record_Extension.
31512 (Build_Record_Init_Proc.Build_Assignment): The default expression in
31513 a component declaration must remain attached at that point in the
31514 tree so New_Copy_Tree copies it if the enclosing record type is derived.
31515 It is therefore necessary to take a copy of the expression when building
31516 the corresponding assignment statement in the init proc.
31517 As a side effect, in the case of a derived record type, we now see the
31518 original expression, without any rewriting that could have occurred
31519 during expansion of the ancestor type's init proc, and we do not need
31520 to go back to Original_Node.
31522 * exp_ch3.ads (Expand_Derived_Record): Rename to
31523 Expand_Record_Extension.
31525 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

31530 subprogram. The proxy object is used as the designated object
31531 for RAS values on the same partition (unless All_Calls_Remote applies).
31532 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
31533 System.Partition_Interface.Get_Unique_Remote_Pointer.
31534 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):

31538 New implementation of expansion for remote access-to-subprogram types,
31539 based on the RACW infrastructure.
31541 * exp_dist.ads (Copy_Specification): Update comment to note that this
31542 function can copy the specification from either a subprogram
31543 specification or an access-to-subprogram type definition.
31545 2004-09-09 Ed Schonberg <schonberg@gnat.com>
31547 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
31548 in an instance, between an explicit subprogram an one inherited from a
31549 type derived from an actual.
31551 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
31552 add a polling call if the subprogram is to be inlined by the back-end,
31553 to avoid repeated calls with multiple inlinings.
31555 * checks.adb (Apply_Alignment_Check): If the expression in the address
31556 clause is a call whose name is not a static entity (e.g. a dispatching
31557 call), treat as dynamic.

31561 * g-trasym.ads: Minor reformatting
31563 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

31572 2004-09-09 Pascal Obry <obry@gnat.com>
31574 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
31575 enable map file generation. Add the right option to generate the map
31576 file if Map_File is set to True.
31578 * gnatdll.adb (Gen_Map_File): New variable.
31579 (Syntax): Add info about new -m (Map_File) option.

31607 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31608 of variable length temporaries for function return now that the
31609 back-end and gigi support it.

31686 consistent treatment of entity references contained within the
31687 enclosed procedure call.
31689 2004-09-01 Vincent Celier <celier@gnat.com>
31691 * bindgen.adb: (Set_EA_Last): New procedure
31692 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure

34260 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
34262 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
34263 corresponding to a private_with must be removed from visibility; it
34264 will be made visible later, just before we analyze the private part of
34266 (Check_Private_Child_Unit): Allow private_with clauses in public
34268 (Install_Siblings): Make visible the private entities of private-withed
34270 (Install_Withed_Unit): Do not install the private withed unit if we
34271 are compiling a package declaration and the Private_With_OK flag was
34272 not set by the caller. These declarations will be installed later,
34273 just before we analyze the private part of the package.
34275 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
34276 during the evaluation of the expression that initializes the object,
34277 decorate it with the expected type to avoid cascade errors.
34280 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
34281 subprogram we have to install the private_with clauses after its
34282 specification has been analyzed (as documented in AI-262.TXT).
34284 * sem_ch8.adb (Has_Private_With): New function. Determines if the
34285 current compilation unit has a private with on a given entity.
34286 (Find_Direct_Name): Detect the Beaujolais problem described in
34289 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
34290 provides the functionality of the function Is_Ancestor that was
34291 previously available in sem_ch10. It has been renamed to avoid
34294 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
34296 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
34298 * utils.c (build_vms_descriptor): Use SImode pointers.

34456 2004-05-13 Diego Novillo <dnovillo@redhat.com>
34458 Merge from tree-ssa-20020619-branch.
34460 * config-lang.in (boot_language, build_by_default): Set
34462 * utils.c (unchecked_convert): Use OEP_ONLY_CONST.

34477 * 5qsystem.ads: Remove Short_Address subtype declaration. Moved to
34480 * s-auxdec.ads: Add Short_Address subtype (moved here from System).
34482 * Makefile.in: [VMS]: Add translation for 5qauxdec.ads.
34484 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
34485 Fixes undefined symbols in IA64 gnatlib.
34487 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
34489 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
34490 Short_Address). This will be moved to system.auxdec.

34494 * sem_util.adb: Replace test for presence of a node that is always
34495 present with a call to Discard_Node.
34497 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
34498 Analyze on the library unit node after generation of distribution stub
34499 constructs. The call was a no-op because Unit_Node has already been
34500 Analyzed, and the tree fragments for the distribution stubs are
34501 analyzed as they are inserted in Exp_Dist.
34502 Update comment regarding to distribution stubs to reflect that we
34503 do not generate stub in separate files anymore.
34505 * einfo.ads: Clarify the fact that a tagged private type has the
34506 E_Record_Type_With_Private Ekind.
34508 * erroutc.adb: Minor reformatting
34510 * erroutc.ads (Max_Msg_Length): Increase to cover possible larger
34511 values if line length is increased using -gnatyM (noticed during code
34514 * eval_fat.adb: Minor reformatting
34515 Put spaces around exponentiation operator
34517 2004-05-10 Ed Schonberg <schonberg@gnat.com>
34520 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): If prefix
34521 has been rewritten as an explicit dereference, retrieve type of
34522 original node to check for possibly unconstrained record type.
34524 2004-05-10 Ed Schonberg <schonberg@gnat.com>
34526 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
34527 overriding, use the operation of the parent unconditionally.
34529 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
34530 operation when either operand is a literal, to avoid further
34533 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
34534 overridden by a previous explicit declaration, mark the previous entity
34537 * sem_disp.adb (Check_Dispatching_Operation): New predicate
34538 Is_Visibly_Controlled, to determine whether a declaration of a
34539 primitive control operation for a derived type overrides an inherited
34540 one. Add warning if the explicit declaration does not override.
34542 2004-05-10 Vincent Celier <celier@gnat.com>
34544 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
34545 some cases when the sources are no longer present.
34547 * make.adb (Collect_Arguments): Fail if an external source, not part
34548 of any project need to be compiled, when switch -x has not been
34551 * makeusg.adb: Document new switch -x
34553 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
34554 defaulted to False.
34556 * switch-m.adb (Scan_Make_Switches): New switch -x
34558 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
34559 gnatmake switch -x.
34561 * gnat_ugn.texi: Document new gnatmake switch -x
34563 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
34565 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
34567 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
34568 (process_attributes): Likewise.
34570 2004-05-10 Joel Brobecker <brobecker@gnat.com>
34572 * s-inmaop.ads: Fix spelling mistake in one of the comments.
34574 2004-05-10 Robert Dewar <dewar@gnat.com>
34576 * gnat_ugn.texi: Document that for config pragma files, the maximum
34577 line length is always 32767.
34579 * gnat_rm.texi: For pragma Eliminate, note that concatenation of string
34580 literals is now allowed.
34582 * gnat-style.texi: Remove statement about splitting long lines before
34583 an operator rather than after, since we do not follow this rule at all.
34584 Clarify rule (really lack of rule) for spaces around exponentiation
34586 * sem_elim.adb: Allow concatenation of string literals as well as a
34587 single string literal for pragma arguments.
34589 * sem_prag.ads, sem_prag.adb: (Is_Config_Static_String): New function
34591 * a-textio.adb (Terminate_Line): Do not add line feed if nothing
34592 written for append case.
34594 * frontend.adb: Changes to avoid checking max line length in config
34597 * g-os_lib.ads: Minor reformatting
34599 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was
34600 wrong in any case. Instead use standard value. Noticed during code
34603 * opt.ads (Max_Line_Length): New field, used to implement removal of
34604 limitation on length of lines when scanning config pragma files.
34606 * osint.ads, prj-dect.adb, prj-strt.adb, prj-tree.adb,
34607 makeutl.ads, makeutl.adb: Minor reformatting
34609 * scn.adb: Do not check line length while scanning config pragma files
34610 Do not check line length while scanning out license information
34612 * scng.adb: Changes to avoid line length checks while parsing config
34615 2004-05-10 GNAT Script <nobody@gnat.com>

35671 * sem_prag.adb (Set_Exported): Warn about making static as result of
35672 export only when the export is coming from source. This may be not
35673 be true e.g. on VMS where we expand export pragmas for exception codes
35674 together with imported or exported exceptions, and we don't want the
35675 user to be warned about something he didn't write.
35677 2004-04-08 Thomas Quinot <quinot@act-europe.fr>
35679 * sem_util.adb (Note_Possible_Modification): Reorganize to remove code
35680 duplication between normal entities and those declared as renamings.
35681 No functional change.
35683 * s-fileio.ads (Form): Remove pragma Inline, as we cannot currently
35684 inline functions returning an unconstrained result.

35780 specified radix_digits is greater or equal to machine_mantissa.
35782 2004-04-05 Javier Miranda <miranda@gnat.com>
35784 * par-ch3.adb: Complete documentation of previous change
35785 Correct wrong syntax documentation of the OBJECT_DECLARATION rule

35798 as is done for non-private derived record types.
35800 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
35801 Ada 2005 AI-310: an abstract non-dispatching operation is not a

35805 expression is Null and target type is not an access type (e.g. a

35810 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
35811 statement whose right-hand side is an inlined call, save a copy of the
35812 original assignment subtree to preserve enough consistency for
35813 Analyze_Assignment to proceed.
35815 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
35816 complete assignment subtree which is now unnecessary, as the expansion
35817 of inlined call has been improved to preserve a consistent assignment
35818 tree. Note_Possible_Modification must be called only
35819 after checks have been applied, or else unnecessary checks will
35822 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35823 of explicit dereferences that do not Come_From_Source:
35824 - be selective on cases where we must go back to the dereferenced
35825 pointer (an assignment to an implicit dereference must not be
35826 recorded as modifying the pointer);
35827 - do not rely on Original_Node being present (Analyze_Assignment
35828 calls Note_Possible_Modification on a copied tree).
35830 * sem_warn.adb (Check_References): When an unset reference to a pointer
35831 that is never assigned is encountered, prefer '<pointer> may be null'
35832 warning over '<pointer> is never assigned a value'.

35901 a string literal, create a temporary for it, constant folding only
35902 handles scalars here.
35904 2004-04-01 Vincent Celier <celier@gnat.com>

36088 2004-03-29 Ed Schonberg <schonberg@gnat.com>
36090 * exp_ch6.adb (Expand_Call): A call to a function declared in the
36091 current unit cannot be inlined if it appears in the body of a withed
36092 unit, to avoid order of elaboration problems in gigi.
36094 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
36095 information for protected (wrapper) operation as well, to simplify gdb
36098 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

36141 a classwide type (for which Is_Object_Reference holds), but it can
36142 also be a value conversion for an access-to-classwide type. In the
36143 latter case, there is an implicit dereference, and the original node
36144 for the prefix does not verify Is_Object_Reference.

36220 case when the source contains only comments.
36222 2004-03-22 Ed Schonberg <schonberg@gnat.com>
36224 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
36225 declaration for a child subprogram body that acts as a spec, indicate
36226 that the entity in the declaration needs debugging information.
36228 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
36229 full view if the subtype is created for a constrained record component;
36230 gigi has enough information to construct the record, and there is no
36231 place in the tree for the declaration.
36233 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
36234 serial number for the dummy body that is built for analysis, to avoid
36235 inconsistencies in the generation of internal names when compiling
36238 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
36240 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
36243 2004-03-22 GNAT Script <nobody@gnat.com>
36245 * Make-lang.in: Makefile automatically updated
36247 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

36274 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
36276 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
36277 as regular exception objects and not as mere integers representing the
36278 condition code. The latter approach required some dynamics to mask off
36279 severity bits, which did not fit well into the GCC table based model.
36280 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
36281 exception data objects. We don't it and it would conflict with the other
36282 external symbol we have to generate for such exceptions.
36284 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
36285 the special code for VMS exceptions, since these are now represented
36286 as regular exceptions objects.
36288 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
36290 * decl.c (debug_no_type_hash): Remove.

36294 2004-03-19 Laurent Guerby <laurent@guerby.net>
36296 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
36297 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
36299 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
36301 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.

36321 * adaint.c: Update comments.
36323 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
36324 GNATLIB_SHARED for FreeBSD.
36326 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
36328 * init.c [VxWorks]: Do not fix the stack size for the environment task.
36329 When needed (stack checking) the stack size is retrieved
36330 from the VxWorks kernel.
36332 * Makefile.in: Flag -nostdinc is required when building the run time
36333 for avoiding looking for files in the base compiler.
36334 Add the VxWorks specific version of the package body for
36335 System.Stack_checking.Operations (5zstchop.adb).
36337 * Make-lang.in: Add the object file for
36338 System.Stack_Checking.Operations.

36346 checking from this package to package System.Stack_Checking.Operations.
36347 This way, stack checking operations are only linked in the final
36348 executable when using the -fstack-check flag.
36350 2004-03-18 Doug Rupp <rupp@gnat.com>
36352 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

36362 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
36363 the procedures Add_To_Path_File.
36364 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
36365 making sure that each directory is present only once and, for object
36366 dirs, when a directory already present is added, the duplicate is
36367 removed and the directory is always put as the last in the table.
36368 Write the path files at the end of these accumulations.
36370 * prj-nmsc.adb (Record_Source): Add source file name in hash table
36371 Files_Htable for all sources.
36373 * prj-proc.adb (Process): Remove restrictions between not directly
36374 related extending projects.

36382 parameter Trusted_Mode.
36384 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
36386 * scn.adb (Determine_License): Take into account a degenerated case
36387 when the source contains only comments.
36389 2004-03-18 Ed Schonberg <schonberg@gnat.com>
36391 * sem_warn.adb (Check_References): For a warning on a selected
36392 component that does not come from source, locate an uninitialized
36393 component of the record type to produce a more precise error message.
36395 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
36397 * 3zsoccon.ads: Fix multicast options.
36399 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
36402 2004-03-15 Robert Dewar <dewar@gnat.com>

36405 pragma used for a private type.
36407 * lib-xref.adb (Generate_Reference): Do not generate warning if
36408 reference is in a different unit from the pragma Unreferenced.
36410 * 5vtpopde.adb: Minor reformatting
36411 Fix casing of To_Task_ID

36414 flag if we have an unchecked conversion to an access type in the same
36417 2004-03-15 Geert Bosch <bosch@gnat.com>
36419 * a-ngcoty.adb (Modulus): In alternate formula for large real or
36420 imaginary parts, use Double precision throughout.
36422 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
36423 we want to be able to compile run-time with -gnata for testing, but
36424 this may also be instantiated in user code that is compiled with -gnata.
36426 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
36428 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
36429 codes. Having a separate type for this is useful to enforce consistency
36430 throughout the various run-time units.
36431 (Exception_Data): Use Exception_Code for Import_Code.
36433 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
36434 Natural and Integer in various places.

36436 with the severity bits masked off.
36437 (Register_VMS_Exception): Handle the additional exception data pointer

36441 component, now reflected by an exported accessor.
36442 (is_handled_by): New routine to compute whether the propagated
36443 occurrence matches some handler choice specification. Extracted out of
36444 get_action_description_for, and expanded to take care of the VMS
36446 (get_action_description_for): Use is_handled_by instead of an explicit
36447 complex condition to decide if the current choice at hand catches the
36448 propagated occurrence.
36450 * raise.h (Exception_Code): New type for C.
36452 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
36453 System.Standard_Library.Exception_Code, to allow references from the
36454 pragma import/export expander.
36456 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
36457 New accessors to allow easy access to GNAT exception data
36459 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
36460 redundant Handled_By_Others component, helper for the personality
36461 routine which will now be able to call the appropriate exception data
36464 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
36465 component of Standard_Exception_Type to be the closest possible to
36466 Exception_Code in System.Standard_Library, that we cannot get at this
36467 point. Expand a ??? comment to notify that this type node should
36468 probably be rewritten later on.
36470 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
36471 registration call to include a pointer to the exception object in the
36474 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
36475 instead of int and explicit bitmasks.
36477 2004-03-15 Vincent Celier <celier@gnat.com>
36479 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
36480 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
36482 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
36483 longer needed now that it is in the spec of
36484 System.Tasking.Task_Attributes.
36486 * adaint.h, adaint.c: (__gnat_create_output_file): New function
36488 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
36490 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
36492 * make.adb (Gnatmake): Do not check the executable suffix; it is being
36493 taken care of in Scan_Make_Arg.
36494 (Scan_Make_Arg): Add the executable suffix only if the argument
36495 following -o, in canonical case, does not end with the executable
36496 suffix. When in verbose mode and executable file name does not end
36497 with executable suffix, output the executable name, in canonical case.
36499 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
36500 to avoid warnings when instantiating Ada.Task_Attributes.
36503 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
36504 in the correct order.
36506 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

36511 directory, instead of the Value.
36512 (Find_Source_Dirs): Remove useless code & comments.
36514 2004-03-15 Ed Schonberg <schonberg@gnat.com>
36516 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
36517 tagged type is inherited, and the parent operation is not frozen yet,
36518 force generation of a freeze node for the inherited operation, so the
36519 corresponding dispatch entry is properly initialized.
36520 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
36521 when looking for user-defined equality operation.
36523 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
36524 boolean when locating primitive equality of tagged component.
36526 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
36527 bit-aligned field and the right-hand side a string literal, introduce
36528 a temporary before expanding assignment into a loop.
36530 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
36531 priority in full, to ensure that any expanded subepxressions of it are
36532 elaborated in the scope of the init_proc.
36534 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
36535 after object declaration, skipping over code that may have been
36536 generated for validity checks.
36538 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
36539 discriminants, ignore the known discriminants of its full view, if
36540 any, to check legality.
36542 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
36543 component if type has unknown discriminants.
36544 (Analyze_Private_Extension_Declaration): Discriminant constraint is
36545 null if type has unknown discriminants.
36547 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
36548 for end label when present.
36550 * s-fileio.adb (Open): When called with a C_Stream, use given name for
36551 temporary file, rather than an empty string.
36553 2004-03-15 Ed Falis <falis@gnat.com>
36555 * s-thread.adb: Removed, no longer used.
36557 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

36577 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
36578 Insert_Dereference_Action when rewriting an implicit dereference into
36579 an explicit one, this will be taken care of during expansion of the
36580 explicit dereference.
36581 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36582 of non-packed slices, since the dereference action generated by
36583 expansion of the explicit dereference is needed in any case.
36584 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36585 analyze and resolve the rewritten explicit dereference so it is seen
36587 (Insert_Dereference_Action): This procedure is now called only for the
36588 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36589 dereferences that do not come from source (including explicit
36590 dereferences resulting from rewriting implicit ones), but do not
36591 recursively insert a check for the dereference nodes contained within
36593 (Insert_Dereference_Action): Clarify and correct comment.

37470 checks for bitfield creation are triggered.
37471 (finish_record_type): During last pass over the fields, clear
37472 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

37816 subtype is not a user-visible entity.
37818 * sem_ch7.adb (Uninstall_Declarations): If an entity in the visible
37819 part is a private subtype, reset the visibility of its full view, if
37820 any, to be consistent.
37823 * sem_ch12.adb (Analyze_Formal_Package): Diagnose properly an attempt
37824 to use a generic package G as a formal package for another generic

37856 2004-01-05 Robert Dewar <dewar@gnat.com>
37858 * 1ssecsta.ads: Default_Secondary_Stack is not a constant since it may
37859 be modified by the binder generated main program if the -D switch is
37862 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
37863 imported functions (since now we expect this to be done for imported
37866 * 5vtaprop.adb: Add several ??? for sections requiring more comments
37867 Minor reformatting throughout
37869 * 5zinit.adb: Minor reformatting
37870 Add 2004 to copyright date
37871 Minor changes to avoid -gnatwa warnings
37872 Correct some instances of using OR instead of OR ELSE (noted while
37873 doing reformatting)
37875 * sprint.adb: Minor updates to avoid -gnatwa warnings
37877 * s-secsta.ads, s-secsta.adb:
37878 (SS_Get_Max): New function to obtain high water mark for ss stack
37879 Default_Secondary_Stack is not a constant since it may be modified by
37880 the binder generated main program if the -D switch is used.
37882 * switch-b.adb: New -Dnnn switch for binder
37885 Make -gnatg imply all warnings currently in -gnatwa
37887 * vms_conv.adb: Minor reformatting
37888 Add 2004 to copyright notice

37912 Minor reformatting and code clean ups.
37913 Minor changes to prevent -gnatwa warnings
37915 * ali.adb: Minor reformatting and cleanup of code
37916 Acquire new SS indication of secondary stack use from ali files
37918 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
37919 (since now we expect this to be done for imported functions)
37921 * bindgen.adb: Generate call to modify default secondary stack size if
37924 * bindusg.adb: Add line for new -D switch
37926 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
37927 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
37928 Add circuitry for both records and arrays to avoid gigi
37929 processing if the type involved has non-bit-aligned components
37931 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37932 N_String_Literal node always references an E_String_Literal_Subtype
37933 entity. This may not be true in the future.
37934 (Possible_Bit_Aligned_Component): Move processing of
37935 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37937 * exp_ch6.adb (Expand_Thread_Body): Pick up
37938 Default_Secondary_Stack_Size as variable so that we get value modified
37939 by possible -Dnnn binder parameter.
37941 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37942 (Type_May_Have_Bit_Aligned_Components): New function.
37944 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

37952 importing constant atomic/volatile objects.
37953 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
37954 unless explicit Pure_Function pragma given, to avoid insidious bug of
37955 call to non-pure imported function getting eliminated.

37977 * rtsfind.adb (Load_Fail): Give full error message in configurable
37978 run-time mode if all_errors mode is set. This was not done in the case
37979 of a file not found, which was an oversight.
37980 Note if secondary stack unit is used by compiler.
37982 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37983 ineffective elaborate all pragmas on non-visible packages (this
37984 happened when a renamed subprogram was called). Now the elaborate all
37985 always goes on the package containing the renaming rather than the one
37986 containing the renamed subprogram.
37988 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37989 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
37991 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
37992 has an Etype that references an E_String_Literal.
37993 (Eval_String_Literal): Avoid assumption that N_String_Literal node
37994 always references an E_String_Literal_Subtype entity. This may not
37995 be true in the future.
37997 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
38000 * sem_res.adb (Resolve): Specialize msg for function name used in proc
38003 2004-01-05 Ed Falis <falis@gnat.com>

38010 * bld.adb: Minor comment updates
38011 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
38014 * make.adb (Gnatmake): Special process for files to compile/check when
38015 -B is specified. Fail when there are only foreign mains in attribute
38016 Main of the project file and -B is not specified. Do not skip bind/link
38017 steps when -B is specified.
38019 * makeusg.adb: Document new switch -B
38021 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
38023 * switch-m.adb: (Scan_Make_Switches): Process -B switch
38025 * vms_data.ads: Add new GNAT PRETTY qualifier

38030 * trans.c (tree_transform, case N_Free_Statement): Handle thin pointer
38033 * misc.c (gnat_printable_name): If VERBOSITY is 2, call
38034 Set_Identifier_Casing.

38037 has size that overflows.
38039 2004-01-05 Gary Dismukes <dismukes@gnat.com>
38041 * exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
38042 -gnatwa warning on static condition.
38044 2004-01-05 Doug Rupp <rupp@gnat.com>
38046 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
38048 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
38050 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
38051 all attributes, including read-only attribute.
38053 2004-01-05 Pascal Obry <obry@gnat.com>

38056 library naming scheme.
38058 * mlib-prj.adb (Build_Library): Generate different names for the static
38059 or dynamic version of the GNAT runtime. This is needed to support the
38060 new shared library naming scheme.
38061 (Process_Binder_File): Add detection of shared library in binder file
38062 based on the new naming scheme.
38064 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
38065 scheme for the shared runtime libraries.
38068 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
38070 (install-gnatlib): Do not create symlinks for shared libraries.
38071 (gnatlib-shared-default): Idem.
38072 (gnatlib-shared-dual-win32): New target. Not used for now as the
38073 auto-import feature does not support arrays/records.
38074 (gnatlib-shared-win32): Do not create copy for the shared libraries.
38075 (gnatlib-shared-vms): Fix shared runtime libraries names.
38077 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
38078 dependent runtime shared library name.
38080 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
38082 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
38085 2004-01-05 Ed Schonberg <schonberg@gnat.com>
38087 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
38088 protected objects when allocator has a subtype indication, not a
38089 qualified expression. Note that qualified expressions may have to be
38090 checked when limited aggregates are implemented.
38092 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
38093 pure, emit warning.
38094 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
38095 subprogram is imported, remove warning.
38097 2004-01-05 Geert Bosch <bosch@gnat.com>
38099 * s-poosiz.adb: Update copyright notice.
38100 (Allocate): Use Task_Lock to protect against concurrent access.
38101 (Deallocate): Likewise.
38103 2004-01-05 Joel Brobecker <brobecker@gnat.com>
38105 * s-stalib.adb (Elab_Final_Code): Add missing year in date inside ???

38135 Ada.Exceptions.Last_Chance_Handler.
38137 2003-12-17 Sergey Rybin <rybin@act-europe.fr>
38139 * cstand.adb (Create_Standard): Change the way how the declaration of
38140 the Duration type is created (making it the same way as it is for all
38141 the other standard types).
38143 2003-12-17 Robert Dewar <dewar@gnat.com>
38145 * s-crtl.ads: Fix header format
38146 Change Pure to Preelaborate
38148 2003-12-17 Ed Schonberg <schonberg@gnat.com>
38150 * checks.adb (Selected_Length_Checks): Generate an Itype reference for
38151 the expression type only if it is declared in the current unit.
38153 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
38154 are universal and already analyzed, as can occur in constrained
38155 subcomponents that depend on discriminants, when one constraint is a
38158 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
38159 type Any_Fixed is legal as the argument of a conversion, if only one
38160 fixed-point type is in context.

38173 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
38174 (Gnatchop): Do not set failure status when reporting the number of
38177 2003-12-15 Doug Rupp <rupp@gnat.com>
38179 * s-ctrl.ads: New file.
38181 * Makefile.rtl (GNAT_RTL_NONTASKING_OBJS): Add s-crtl$(objext).
38183 * Make-lang.in: (GNAT_ADA_OBJS): Add ada/s-crtl.o.
38184 (GNATBIND_OBJS): Add ada/s-crtl.o.

38199 * Make-lang.in: Makefile automatically updated
38201 2003-12-11 Ed Falis <falis@gnat.com>
38203 * 5zinit.adb: Clean up.
38205 * 5zintman.adb (Notify_Exception): replaced case statement with a call
38206 to __gnat_map_signal, imported from init.c to support
38207 signal -> exception mappings that depend on the vxWorks version.
38210 Created and exported __gnat_map_signal to support signal -> exception
38211 mapping that is dependent on the VxWorks version.

38221 __gnat_handler_installed, as done on all other platforms.
38222 Remove duplicated code.
38224 2003-12-11 Jerome Guitton <guitton@act-europe.fr>
38226 * Makefile.in (rts-zfp, rts-ravenscar): Create libgnat.a.
38228 2003-12-11 Thomas Quinot <quinot@act-europe.fr>
38230 * sinfo.ads: Fix inconsistent example code in comment.
38232 2003-12-11 Robert Dewar <dewar@gnat.com>
38234 * a-tiinau.adb: Add a couple of comments
38236 * sem_ch3.adb: Minor reformatting
38239 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
38240 Minor reformatting throughout
38242 2003-12-11 Ed Schonberg <schonberg@gnat.com>
38244 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
38245 bounds of a loop, create a separate block in order to generate proper
38246 cleanup actions to prevent memory leaks.
38248 * sem_res.adb (Resolve_Call): After a call to
38249 Establish_Transient_Scope, the call may be rewritten and relocated, in
38250 which case no further processing is needed.
38252 * sem_util.adb: (Wrong_Type): Refine previous fix.
38253 Fixes ACATS regressions.
38256 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
38259 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
38261 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
38262 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
38265 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
38268 2003-12-08 Robert Dewar <dewar@gnat.com>
38270 * 7sintman.adb: Minor reformatting
38272 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
38273 standard linker options to get standard libraries linked. We now plan
38274 to provide dummy versions of these libraries to match the appropriate
38275 configurable run-time (e.g. if a library is not needed at all, provide
38276 a dummy empty library).
38278 * targparm.ads: Configurable_Run_Time mode no longer affects linker
38279 options (-L parameters and standard libraries). What we plan to do is
38280 to provide dummy libraries where the libraries are not required.
38282 * gnatbind.adb: Minor comment improvement
38284 2003-12-08 Javier Miranda <miranda@gnat.com>
38286 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
38287 aggregate in the parent. Otherwise constants with limited aggregates
38288 are not supported. Add new formal to pass the component type (Ctype).
38289 It is required to call the corresponding IP subprogram in case of
38290 default initialized components.
38291 (Gen_Assign): In case of default-initialized component, generate a
38292 call to the IP subprogram associated with the component.
38293 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
38294 of aggregate with default initialized components.
38295 (Has_Default_Init_Comps): Improve implementation to recursively check
38296 all the present expressions.
38298 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
38299 to indicate that the initialization call corresponds to a
38300 default-initialized component of an aggregate.
38301 In case of default initialized aggregate with tasks this parameter is
38302 used to generate a null string (this is just a workaround that must be
38303 improved later). In case of discriminants, this parameter is used to
38304 generate a selected component node that gives access to the discriminant
38307 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
38308 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
38309 allocated aggregates with default-initialized components.
38311 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
38312 the box notation is used in positional aggregates.

38320 * prj.adb (Project_Empty): New component Unkept_Comments
38321 (Scan): Remove procedure; moved to Prj.Err.
38323 * prj.ads (Project_Data): New Boolean component Unkept_Comments
38324 (Scan): Remove procedure; moved to Prj.Err.
38326 * prj-dect.adb: Manage comments for the different declarations.
38328 * prj-part.adb (With_Record): New component Node

40066 * mingw32.h: New file.
40067 * gnat_wrapper.adb: New file.
40069 2003-10-22 Jerome Roussel <roussel@act-europe.fr>
40071 * g-regpat.ads, g-regpat.adb (Match): new function, to know if a
40072 string match a pre compiled regular expression (the corresponding
40073 version of the function working on a raw regular expression)
40074 Fix typos in various comments
40075 Update copyright notice in spec
40077 2003-10-21 Gary Dismukes <dismukes@gnat.com>
40080 (Component_Needs_Simple_Initialization): Return False when the type is a
40081 packed bit array. Revise spec comments to document this case.
40084 (Expand_Pragma_Import): Set any expression on the imported object to
40085 empty to avoid initializing imported objects (in particular this
40086 covers the case of zero-initialization of bit arrays).
40087 Update copyright notice.
40089 2003-10-21 Ed Schonberg <schonberg@gnat.com>
40092 (Load_Parent_Of_Generic): If parent is compilation unit, stop search,
40093 a subunit is missing.
40094 (Instantiate_Subprogram_Body): If body of function is missing, set type
40095 of return expression explicitly in dummy body, to prevent cascaded
40096 errors when a subunit is missing.
40100 (Access_Subprogram_Declaration): Verify that return type is valid.
40104 (Check_Elab_Calls): Do not apply elaboration checks if the main unit is
40109 (Corresponding_Discriminant): If the scope of the discriminant is a
40110 private type without discriminant, use its full view.

42117 (general) Add @./@: where approriate, and two spaces after the
42118 full stop at the end of a sentence. Use @samp markup when
42119 referring concrete lexical entities (keywords, attribute names
42120 etc.), and @syntax for ARM grammar elements. Use @r for English

42135 * make.adb (Add_Switch): Make Generic_Position a procedure. The
42136 function approach did not work well because of a side effect (the
42137 function call could reallocate the table which was being indexed
42138 using its result). Fixes ada/4851.

42197 Add 2001 to copyright date
42199 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
42200 need to force universal inlining for these cases.

42416 When using a project file, fail if specified executable is relative
42417 path with directory information, and prepend executable, if not

42502 there could be a real problem here with an uninitialized reference
42503 to Hbound, but no actual example of failure has been found.
42505 2001-12-17 Laurent Pautet <pautet@gnat.com>
42508 Fix comment of Shutdown_Socket and Close_Socket. These functions
42509 should not fail silently because if they are called twice, this
42510 probably means that there is a race condition in the user program.
42511 Anyway, this behaviour is consistent with the rest of this unit.
42512 When an error occurs, an exception is raised with the error message
42513 as exception message.
42515 2001-12-17 Robert Dewar <dewar@gnat.com>

43852 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43853 instead of simple checksum.
43854 (CRC_Match): new function.
43855 (CRC_Error): new constant.
43857 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43858 a CRC now and not a simple checksum. A CRC uses lower-case hex
43859 letters, fixes ambiguity in parsing.
43861 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43862 is what this variable will store.
43864 * bcheck.adb: Change reference to chechsum in comments by CRC.
43865 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43866 rename All_Checksum_Match to All_CRC_Match. Change due to API
43867 renaming since now GNAT does not use a simple checksum but a
43868 CRC using GNAT.CRC32.
43870 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43871 now and not anymore a simple checksum.

43908 Update comments for the CRC.
43910 * types.adb (Hex): Use lowercase for the letter part.
43912 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43913 for a word. This is currently used only for CRC. In previous version,
43914 the checksum was using a representation with all letter being
43915 upper-case. With the new implementation (using CRC) we do not remove
43916 the 32th bit of the CRC, so we can have an upper-case starting letter
43917 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43918 It is ambigous since the CRC was optional and could be followed by
43919 options like EB, EE. So now this routines uses lower-case letter for
43920 the hexadecimal representation. Strange enough only lower case letters
43921 where checked in Scan_ALI (even if this was not a possible case).
43923 * gnatvsn.ads (Library_Version): changed to 3.15a.
43925 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43928 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
