2641 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2642 Orig_Prev to Prev in the case where the actual is N_Function_Call or
2643 N_Identifier. This was interfering with other cases that are rewritten
2644 as N_Identifier, such as allocators, resulting in passing of the wrong

4737 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4738 convention from its base type, do not set the type to that of integer,

4805 New local subprogram Is_Valid_Remote_Object_Type, replaces
4806 Is_Recursively_Limited_Private.
4807 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4808 non-controlling formals (and the return type, even though this is not
4809 explicit in the standard) must support external streaming.

4811 as above for of RAS types and RCI subprograms. (The return type is not

4817 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4818 Is_Remote_Call_Interface to identify RACW types in a stable and
4819 consistent way. We used to rely in this predicate on the privateness of
4820 the designated type and its ancestors, but depending on the currently
4821 visible private parts, this caused false negatives. We now uniformly
4822 rely on checks made at the point where the RACW type is declared.

4836 Add missing escaping of all-caps word 'CPP' in error messages.
4837 (Build_Discriminated_Subtype): Do not inherit representation clauses
4838 from parent type if subtype already carries them, because they are
4839 inherited earlier during derivation and already include those that may
4840 come from a partial view.
4842 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4843 Check the declarations of a subprogram body for proper deferred

4877 (Add_One_Interp): Ignore any interpretation that is a primitive
4878 operation of an RACW stub type (these primitives are only executed
4879 through dispatching, never through static calls).
4880 (Collect_Interps): When only one interpretation has been found, set N's
4881 Entity and Etype to that interpretation, otherwise Entity and Etype may
4882 still refer to an interpretation that was ignored by Add_One_Interp,
4883 in which case would end up with being marked as not overloaded but with
4884 an Entity attribute not pointing to its (unique) correct interpretation.
4886 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4889 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

4943 equivalent representation, but has the advantage of allowing
4944 compilation of this file under 64 bits platforms.

9144 WITH clause on a private sibling.
9145 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
9146 child unit is a renaming, create an implicit with_clause on that

9249 perform subtype conformance between the formals of the current entry
9250 and those of the target interface primitive.
9251 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
9252 Timed_Entry_Call): Analyze the triggering statement as the first step of
9253 the processing. If this is a dispatching select, postpone the analysis
9254 of all select statements until the Expander transforms the select. This

9256 replicated some of the select statements. In case the Expander is
9257 disabled, perform regular analysis.
9258 (Check_Triggering_Statement): New routine.
9259 (Analyze_Requeue): Exclude any interpretations that are not entries when
9260 checking overloaded names in a requeue. Also test type conformance for
9261 matching interpretations rather than requiring subtype conformance at

9269 for the defaulted actual.
9271 2007-12-13 Geert Bosch <bosch@adacore.com>
9273 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

9853 a predefined entity (as happens for array index types), the line is set
9855 Add support for parsing multiple array index types info, or
9856 multiple inherited interfaces info. This information cannot be stored
9857 in Xref_Entity_Record, which only supports a single instance of Tref_*,

9873 Dismukes). After this patch there is no need to perform any
9874 additional management on these nodes in Expand_Interface_Actuals.
9876 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9877 that handles use of 'Access and 'Unchecked_Access applied to
9878 actuals covering interface types. Such code is now
9879 centralized in Expand_N_Attribute_Reference.
9881 2007-10-15 Ed Schonberg <schonberg@adacore.com>

9884 of tagged types whose ultimate ancestor is a CPP type.

9920 for unsupported configurations; use it on VMS targets instead of the

9923 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9924 used by VxWorks targets to have access to task-specific data and be
9925 able to extract the stack boundaries for stack checking.

9969 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9970 association for an access component, add an association with null as
9971 the expression. Remove testing for array subtypes and the setting in
9972 that case of Ctyp to the array component type, which prevented proper
9973 inclusion of an association for null-initialized arrays. Collapse
9974 condition that tests for array subtypes into just a test of
9975 Is_Partially_Initialized_Type (which already covers arrays anyway).

9993 (Analyze_Allocator): When the designated type of an unconstrained
9994 allocator is a record with unknown discriminants or an array with
9995 unknown range bounds, emit a detailed error message depending on the
9996 compilation mode and whether the designated type is limited.

10131 between source files and line maps.
10132 (Sloc_to_locus): If mapped location support is enabled, translate
10133 source location into mapped location.
10134 (annotate_with_node): Rename into set_expr_location_from_node.
10135 Call set_expr_location instead of annotate_with_locus.
10136 (Pragma_to_gnu): Adjust for above change.
10137 (Loop_Statement_to_gnu): Likewise.
10138 (call_to_gnu): Likewise.

10161 Add a section on leap seconds control along with two entities used to
10162 enable and disable leap seconds support. The array Leap_Second_Times is
10163 now constant and contains hard time values pre-generated. Remove
10164 all elaboration code used to populate the table of leap seconds.
10167 Add entity Leap_Seconds_Support to the list of global run-time variables
10168 along with a comment on its usage and values.
10169 (Gen_Adainit_Ada): Add code to generate the declaration and import of
10170 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
10171 or one (enabled) depending on the presence of binder switch "-y".

10173 __gl_leap_seconds_support. Set is value to zero (disabled) or one
10174 (enabled) depending on the presence of binder switch "-y".
10176 * init.c: Add __gl_leap_seconds_support to the list of global values
10177 computed by the binder.
10179 2007-09-26 Jerome Guitton <guitton@adacore.com>

10184 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
10186 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
10188 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
10189 function which can be called by the debugger to interrupt the tasks of
10190 an Ada application asynchronously, as needed on VxWorks.
10191 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
10193 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
10194 renamed from Stop_All_Tasks. Update comments.
10195 (Stop_All_tasks): New function declaration.
10197 2007-09-26 Olivier Hainque <hainque@adacore.com>
10199 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
10200 #include <utime.h> and #define GCC_RESOURCE_H before

10217 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
10220 * sem_dist.ads: Minor comment fix
10222 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
10224 2007-09-26 Javier Miranda <miranda@adacore.com>
10225 Eric Botcazou <ebotcazou@adacore.com>
10228 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
10229 indirection added to the HT_Link component of the TSD. This is required
10230 to statically allocate the TSD.
10233 Minor reordering of the declarations in the private part. Required to
10234 add a level of indirection to the contents of the TSD component HT_Link.
10235 This is required to statically allocate the TSD.
10237 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
10238 Is_Statically_Allocated set from constant objects.
10239 Do not make exported constants created by the compiler volatile.
10240 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
10243 * trans.c (Identifier_to_gnu): For constants, unshare initializers
10244 before returning them.
10246 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
10247 public part of the package.
10248 (Make_DT): Move HT_Link component out of the TSD record. For this
10249 purpose Make_DT now declares a separate object that stores the
10250 HT_Link value, and initializes the TSD component with the address
10251 of this new object. The addition of this level of indirection is
10252 required to statically allocate the TSD because the TSD cannot
10253 have variable components.
10254 (Expand_Interface_Conversion): Improve the expanded code.
10255 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
10257 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
10258 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
10259 if we are building static dispatch tables then we must not generate
10260 extra code to register the primitive because the dispatch table will
10261 be built at the end of the library package; otherwise we notify that
10262 we cannot build the static dispatch table.
10264 2007-09-26 Robert Dewar <dewar@adacore.com>
10266 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
10269 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
10270 (Analyze_Record_Representation_Clause): Suppress junk warning for
10271 missing component clause.

10281 for thunks associated with interface types.
10283 * einfo.ads: Improve documentatation of Is_Internal
10284 (Is_Thunk): New attribute applicable to subprograms. True for thunks
10285 associated with interface types.
10286 Extensive comment fixes regarding flags that appear in all entities. The
10287 documentation is now consistent for all such flags (there were a number
10288 of errors in the documentation in this regard).
10290 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
10292 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
10293 of these procedures are passed a function call that already has
10294 build-in-place actuals (testing new flag
10295 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
10296 the case where processing continues.
10297 (Expand_Call): If the call is generated from a thunk body then we
10298 propagate the extra actuals associated with the accessibility
10299 level of the access type actuals.
10301 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
10302 of each extra formal of a protected operation to reference the
10303 corresponding extra formal of the subprogram denoted by the
10304 operation's Protected_Body_Subprogram.
10306 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
10307 N_Function_Call nodes.
10309 2007-09-26 Robert Dewar <dewar@adacore.com>
10311 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
10313 * debug.adb: Add d.s flag.
10315 2007-09-26 Gary Dismukes <dismukes@adacore.com>
10317 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
10318 debug variable so that it won't be initialized when pragma
10319 Initialize_Scalars is in effect.
10321 2007-09-26 Gary Dismukes <dismukes@adacore.com>
10323 * freeze.adb (Freeze_Entity): Remove check for preelaborable
10324 initialization of a full view. This is moved to
10325 Analyze_Package_Specification.
10327 * sem_ch7.adb (Analyze_Package_Specification): Add check for
10328 preelaborable initialization of a full view in entity loop.
10329 (Uninstall_Declarations): If entity is a use-visible compilation unit,
10330 its child units are use-visible only if they are visible child units.
10332 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
10333 whether an expression can be used within a type declaration that
10334 requires preelaborable init.
10335 (Check_Components): Replace inline code that does partial checking for
10336 preelaborable default expressions with call to
10337 Is_Preelaborable_Expression.
10338 (Has_Preelaborable_Initialization): In the case of a generic actual
10339 subtype, (that is, Is_Generic_Actual is True), return the result of
10340 applying Has_Preelaborable_Initialization to the generic actual's base
10343 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
10345 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
10346 call to Jan_1_Day _Of_Week to optimize its performance.
10347 (Is_Leap): Move the routine to the scope of Week_In_Year.
10348 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
10349 weekday on which January 1 falls of Year - 1 and Year + 1. This function
10350 avoids calling Time_Of and Split, thus making it more efficent.
10351 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
10353 * g-calend.ads (Week_In_Year): Change comment to reflect new
10356 2007-09-26 Emmanuel Briot <briot@adacore.com>
10358 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
10359 Command_Line): New types
10360 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
10361 support for defining how switches can be grouped on a command line (as
10362 is the case for -gnatw... for GNAT), and how simple switches can be
10363 used as aliases for more complex switches (-gnatwa is same as
10365 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
10366 (Start, Current_*): New subprograms
10367 Added support for parsing an array of strings in addition to the real
10369 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
10370 be moved from the body to the private part of the spec.
10371 (*): All subprograms now have an extra parameter with default value to
10372 specify which parser should be used. For backward compatibility, it
10373 defaults to parsing the command line of the application. They were also
10374 modified to properly handle cases where each of the argument does not
10375 start at index 1 (which is always true for Ada.Command_Line, but not
10376 when processing any Argument_List).
10377 (Free): New subprogram
10378 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
10379 Argument): New subprograms
10380 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
10381 special characters like ':', '=',... are now handled in a single place,
10382 which makes the code more extensible eventually.
10383 (Getopt, Full_Switch): When the switch was returned as part of the
10384 special character '*', make sure it is prepended by the switch character
10385 ('-' in general), so that the application knows whether "foo" or "-foo"
10386 was specified on the command line.
10388 2007-09-26 Florian Villoing <villoing@adacore.com>
10390 * g-dirope.adb (Remove_Dir): In case we are removing directories
10391 recursively, make sure that if an exception is raised during the
10392 processing, the current working directory is reset to its initial
10393 value before propagating the exception.
10395 2007-09-26 Vincent Celier <celier@adacore.com>
10397 * gnatbind.adb: If there are several ALI files specified and there is
10398 a main program to bind, the first ALI is expected to contain the main
10399 subprogram and the names of the binder generated files will be derived
10400 from the first ALI file name.
10401 (Gnatbind): Fix insertion character in invocation of Error_Msg
10403 2007-09-26 Vincent Celier <celier@adacore.com>
10405 * gnatcmd.adb (Check_Files): Do not include sources that have been
10406 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
10408 2007-09-26 Ed Schonberg <schonberg@adacore.com>
10410 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
10411 information about each of its index types, following the type
10412 reference for its component type.
10414 2007-09-26 Vincent Celier <celier@adacore.com>
10416 * make.adb: (Kill): New procedure (__gnat_kill imported)
10417 (Running_Compile, Outstanding_Compiles): Global variables that
10418 were previously local to procedure Compile_Sources.
10419 (Sigint_Intercepted): Send signal SIGINT to all outstanding
10420 compilation processes.
10422 (Gnatmake): If project files are used, create the mapping of all the
10423 sources, so that the correct paths will be found.
10425 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
10427 2007-09-26 Vincent Celier <celier@adacore.com>
10429 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
10431 * prj.ads, prj.adb (Default_Language): Remove function, no longer used

10438 * prj-attr.adb: New attributes Required_Switches (<language>) in
10439 packages Compiler and Binder.
10441 * prj-nmsc.adb: Major rewrite of the processing of configuration
10442 attributes for gprbuild. No impact on GNAT tools.
10444 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
10445 process configuration attributes: this is done in Prj.Nmsc.Check.
10446 (Recursive_Process): Make a full copy of packages inherited from project
10447 being extended, instead of a shallow copy.
10448 (Process_Project_Tree_Phase_1): New procedure
10449 (Process_Project_Tree_Phase_1): New procedure
10450 (Process): Implementation now uses the two new procedures
10452 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
10453 from the project config, not the tree config that no longer exists.

10467 * par-ch4.adb (P_Record_Or_Array_Component_Association): Change Ada 95
10468 message to cite use of <> in aggregate component associations rather
10469 than wrongly indicating use of limited aggregates.
10471 2007-09-26 Robert Dewar <dewar@adacore.com>
10473 * sem_attr.adb (Analyze_Access_Attribute): Fix missing set of
10476 2007-09-26 Ed Schonberg <schonberg@adacore.com>
10478 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
10479 ancestor of the derived type, the operations are inherited from the
10480 primary dispatch table of the parent.
10481 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
10482 when the context is an explicit type conversion.
10484 2007-09-26 Ed Schonberg <schonberg@adacore.com>
10486 * sem_ch4.adb (Analyze_Qualified_Expression): Apply name resolution
10487 rule for qualified expressions properly, to detect improper conversions
10488 and resolve some cases of overloading.

10781 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
10782 create an abstract subprogram in the case of 'Input. For 'Output we now
10783 create a real spec/body when the type is abstract, since it can
10784 potentially be called.
10785 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10786 body for 'Output when the type is abstract (only the creation of the
10787 body for 'Input is excluded when the type is abstract).
10788 (Stream_Operation_OK): Add an additional condition in the return
10789 statement, so that False will be returned for TTS_Stream_Input if the
10790 associated tagged type is an abstract extension. Add comments for
10792 (Expand_N_Object_Declaration): For the case of a shared passive
10793 variable, insert init proc call only after the shared variable
10794 procedures have been processed, because the IP call needs to undergo
10795 shared passive variable reference expansion, which requires these
10796 procedures to be available (and elaborated).

10808 type, retrieve its value from the aggregate itself, where it must have
10811 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10812 to remove other spurious ambiguities on arithmetic operations involving
10813 literals and addresses, on systems where Address is a visible integer
10814 type, when the operator is called in functional notation.
10815 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10816 is legal when the types match, even if the operation is currently
10819 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10821 * sem_ch12.adb (Build_Local_Package): A formal package with no
10822 associations is legal if all formals have defaults. It is not

10858 the N_Indexed_Component case.
10859 <N_Indexed_Component>: Fall through to above case.

10947 exceptions never being raised.
10948 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

10969 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10970 occurring in the list of entities to qualify, and do not attempt to
10971 traverse an entity list in that case. Variables associated with
10972 ` library-level package renamings can now occur in the table.

10996 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10997 concatenations of string literals into a single literal, in order to
10998 avoid very deep recursion in the front end, which was causing stack
11001 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
11002 string, and the right operand is a string literal (the case of "" &
11003 "..."), optimize by avoiding copying the right operand -- just use the
11004 value of the right operand directly.
11006 * stringt.adb (Store_String_Chars): Optimize by growing the
11007 String_Chars table all at once, rather than appending characters one by
11009 (Write_String_Table_Entry): If the string to be printed is very long,
11010 just print the first few characters, followed by the length. Otherwise,
11011 doing "pn(n)" in the debugger can take an extremely long time.
11013 * sem_prag.adb (Process_Interface_Name): Replace loop doing
11014 Store_String_Char with Store_String_Chars.

11033 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
11034 flag, for effiency. It is called when analyzing arithmetic operators
11035 and also for actuals in calls that are universal_integers. The flag is
11036 set for the predefined type address, and for any type or subtype
11039 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
11040 Universal_Integer, when the formal is a descendent of address and the
11041 call appears in user code.
11042 (Analyze_Selected_Component): if the prefix is a private extension, the
11043 tag component is visible.

11108 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
11109 associated with Standard_Debug_Renaming_Type, to be used as the type of

11113 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
11114 (Set_Debug_Renaming_Link): Change to set Node25.

11124 and the entity of the renaming declaration.
11125 (Qualify_Entity_Name): Add the delayed qualification of the entity name
11126 part of the name of a variable that has a Debug_Renaming_Link.
11128 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a

11133 Ed Schonberg <schonberg@adacore.com>
11134 Javier Miranda <miranda@adacore.com>
11136 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
11137 ancestor part given by an aggregate to test for an unchecked conversion,
11138 since this can occur in some cases when the ancestor part is a function
11139 call, and we don't want to fall into the recursive call to this
11140 procedure in that case.
11142 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
11143 stream attributes on limited types to account for user-specified
11144 attributes as well as whether Input (resp. Output) becomes available
11145 due to Read (resp. Write) being available for the type. Change Boolean
11146 variable to the more accurate name
11147 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
11148 double-"not" predicate at beginning of return statement to more
11149 understandable form.
11151 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
11152 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
11153 in a block statement and use that as the first statement of the
11154 expanded return rather than incorrectly using the handled sequence as
11155 the first statement.
11157 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
11158 operation, generate an explicit freeze node for it rather than
11159 generating extra formals, to ensure that gigi has the proper order of
11160 elaboration for anonymous subtypes in the signature of the subprograms.
11161 (Build_In_Place_Formal): Move assertion to beginning of loop.
11162 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

11165 applied to a function call (occurs for some cases of 'Input).
11167 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
11168 2005, generate an extended return statement enclosing the result object
11171 * freeze.adb (Freeze_Record_Type): Extend the current management of
11172 components that are access type with an allocator as default value: add
11173 missing support to the use of qualified expressions of the
11174 allocator (which also cause freezing of the designated type!)
11175 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
11176 dispatching operation, since extra formals may be needed by calls to
11177 build-in-place functions (such as stream 'Input).
11179 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
11180 formals for 'Constrained and accessibility level in the case of a
11181 predefined dispatching operation.
11183 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
11184 point, no need to find the parent node.
11186 2007-08-16 Javier Miranda <miranda@adacore.com>
11188 * exp_attr.adb (Attribute_Priority): Add missing support for entries
11189 and entry barriers.
11191 2007-08-16 Javier Miranda <miranda@adacore.com>
11193 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
11194 is not really required and can introduce regression with the debugger.
11195 The original problem is fixed with the patch written for checks.adb.
11197 2007-08-16 Thomas Quinot <quinot@adacore.com>
11199 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

11205 Including_Non_Switch set to False.
11206 (Gnatmake): For the compiler, call Test_If_Relative_Path with
11207 Including_Non_Switch set to False.
11209 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
11210 parameter Including_Non_Switch, defaulted to True. When
11211 Including_Non_Switch is False, options that are not switches and
11212 appear as relative path are not converted to absolute paths.
11214 2007-08-16 Nicolas Roche <roche@adacore.com>

11228 (Install_Limited_Withed_Unit): Do not install the limited view of
11229 package P if P is reachable through an ancestor chain from package C

11232 (Has_With_Clause): New routine.
11234 2007-08-16 Ed Schonberg <schonberg@adacore.com>
11236 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
11237 generic for an enclosing instance is a global reference, even though
11238 its scope is the enclosing instance.

11257 implements an operation inherited from a progenitor interface, verify
11258 that they are subtype-conformant.

11264 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
11265 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
11266 the statement which is being resolved comes from a predefined library
11267 unit, all non-predefined library interpretations are skipped.
11268 (Resolve_Op_Concat): If string concatenation was folded in the parser,
11269 but the "&" is user defined, give an error, because the folding would

11332 needed for access to concurrent record types generated by the expander.
11333 (Generate_Range_Check): When generating a temporary to capture the
11334 value of a conversion that requires a range check, set the type of the

11363 access parameter, do not apply an accessibility check when the
11364 operand's original node was an attribute other than 'Access. We now
11365 create access conversions for the expansion of 'Unchecked_Access and
11366 'Unrestricted_Access in certain cases and clearly accessibility should
11367 not be checked for those.
11369 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
11370 includes a type conversion of a packed component that has been expanded,
11371 recover the original expression for the object, and use this expression
11372 in the post-call assignment statement, so that the assignment is made
11373 to the object and not to a back-end temporary.
11374 (Freeze_Subprogram): In case of primitives of tagged types not defined
11375 at the library level force generation of code to register the primitive
11376 in the dispatch table. In addition some code reorganization has been
11377 done to leave the implementation clear.
11378 (Expand_Call): When expanding an inherited implicit conversion,
11379 preserve the type of the inherited function after the intrinsic
11380 operation has been expanded.
11382 * exp_ch2.ads, exp_ch2.adb
11383 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
11384 of an entry formal appearing in an assignment statement does not assign
11386 (Expand_Current_Value): Instead of calling a routine to determine
11387 whether the prefix of an attribute reference should be optimized or
11388 not, prevent the optimization of such prefixes all together.
11390 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
11391 component whose prefix is known to be of an access type is an implicit
11392 dereference and does not assign to the prefix.
11394 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11395 Robert Dewar <dewar@adacore.com>
11397 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
11398 itype is visited, make an entry into table to link associated node and
11400 Add comments and correct harmless error in Build_NCT_Hash_Tables
11401 (Array_Aggr_Subtype): Associate each itype created for an index type to
11402 the corresponding range construct, and not to the aggregate itself. to
11403 maintain a one-to-one correspondence between itype and its associated
11404 node, to prevent errors when complex expression is copied.
11405 Fix mishandling of multiple levels of parens
11407 * sem_aggr.adb: Create a limited view of an incomplete type, to make
11408 treatment of limited views uniform for all visible declarations in a
11409 limited_withed package.
11410 (New_Copy_Tree): If hash table is being used and itype is visited,
11411 make an entry into table to link associated node and new itype.
11412 (Resolve_Record_Aggregate): Do not add an others box association for a
11413 discriminated record component that has only discriminants, when there
11414 is a box association for the component itself.
11416 * par-ch4.adb: Fix mishandling of multiple levels of parens
11418 2007-08-14 Robert Dewar <dewar@adacore.com>
11420 * comperr.adb: Fix problem with suppressing warning messages from gigi

11454 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
11455 to make treatment of limited views uniform for all visible declarations
11456 in a limited_withed package.
11457 Improve warnings for in out parameters
11458 (Set_Related_Interaface/Related_Interface): Allow the use of this
11459 attribute with constants.
11460 (Write_Field26_Name): Handle attribute Related_Interface in constants.
11461 Warn on duplicate pragma Preelaborable_Initialialization
11463 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
11464 generation of a freezing node to ensure proper management of null
11465 excluding access types in the backend.
11466 (Create_Extra_Formals): Test base type of the formal when checking for
11467 the need to add an extra accessibility-level formal. Pass the entity E
11468 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
11469 originally being done in a couple of cases), to ensure that the
11470 Extra_Formals list gets set on the entity E when the first entity is
11472 (Conforming_Types): Add missing calls to Base_Type to the code that
11473 handles anonymous access types. This is required to handle the
11474 general case because Process_Formals builds internal subtype entities
11475 to handle null-excluding access types.
11476 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11477 functions that need it, even when not marked Requires_Overriding.
11478 Improve warnings for in out parameters
11479 (Analyze_Function_Return): Warn for disallowed null return
11480 Warn on return from procedure with unset out parameter
11481 Ensure consistent use of # in error messages
11482 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
11483 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
11484 the implicit conversion of the expression done for anonymous access
11485 types. This is required to generate the code of the null excluding
11486 check (if required).
11488 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
11489 A formal parameter is never publicly referenceable outside of its body.
11490 (Check_References): For an unreferenced formal parameter in an accept
11491 statement, use the same warning circuitry as for subprogram formal
11493 (Warn_On_Unreferenced_Entity): New subprogram, taken from
11494 Output_Unreferenced_Messages, containing the part of that routine that
11495 is now reused for entry formals as described above.
11496 (Goto_Spec_Entity): New function
11497 (Check_References): Do not give IN OUT warning for dispatching operation
11498 Improve warnings for in out parameters

11505 Javier Miranda <miranda@adacore.com>
11506 Gary Dismukes <dismukes@adacore.com>
11508 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
11509 (Expand_N_Attribute_Reference): Further unify the handling of the
11510 three forms of access attributes, using common code now for all three
11511 cases. Add a test for the case of applying an access attribute to
11512 an explicit dereference when the context is an access-to-interface
11513 type. In that case we need to apply the conversion to the prefix
11514 of the explicit dereference rather than the prefix of the attribute.
11515 (Attribute_Version, UET_Address): Set entity as internal to ensure
11516 proper dg output of implicit importation.
11517 (Expand_Access_To_Type): Removed.
11518 (Expand_N_Attribute_Reference): Merge the code from the three cases
11519 of access attributes, since the processing is largely identical for
11520 these cases. The substantive fix here is to process the case of a
11521 type name prefix (current instance case) before handling the case
11522 of interface prefixes.

11527 Robert Dewar <dewar@adacore.com>
11529 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
11530 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
11531 type that is an anonymous access to controlled object, establish
11532 an associated finalization chain to avoid corrupting the global
11533 finalization list when a dynamically allocated object designated
11534 by such a component is deallocated.
11535 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11536 functions that need it, even when not marked Requires_Overriding.
11537 (Initialize_Tag): Replace call to has_discriminants by call to
11538 Is_Variable_Size_Record in the circuitry that handles the
11539 initialization of secondary tags.
11540 (Is_Variable_Size_Record): New implementation.
11541 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
11542 Suppress_Initialization pragma for a derived type.
11543 (Is_Variable_Size_Record): New subprogram.
11544 (Build_Offset_To_Top_Functions): New implementation that simplifies the
11545 initial version of this routine and also fixes problems causing
11546 incomplete initialization of the table of interfaces.
11547 (Build_Init_Procedure): Improve the generation of code to initialize the
11548 the tag components of secondary dispatch tables.
11549 (Init_Secondary_Tags): New implementation that simplifies the previous
11550 version of this routine.
11551 (Make_DT): Add parameter to indicate when type has been frozen by an
11552 object declaration, for diagnostic purposes.
11553 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
11554 diagnose attemps to freeze a subprogram when some untagged type of its
11555 profile is a private type whose full view has not been analyzed yet.
11556 (Freeze_Array_Type): Generate init proc for packed array if either
11557 Initialize or Normalize_Scalars is set.
11558 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
11559 constructing the new profile, copy the null_exclusion indicator for each
11560 parameter, to ensure full conformance of the new body with the spec.
11562 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
11563 Create wrappers for constructor functions that need it, even when not
11564 marked Requires_Overriding.
11565 (Covers): Handle properly designated types of anonymous access types,
11566 whose non-limited views are themselves incomplete types.
11567 (Add_Entry): Use an entity to store the abstract operation which hides
11569 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
11570 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
11571 initialization aggregate.
11572 (Function_Interp_May_Be_Hidden): Rename to
11573 Function_Interp_Has_Abstract_Op.
11574 (Has_Compatible_Type): Remove machinery that skips interpretations if
11575 they are labeled as potentially hidden by an abstract operator.
11576 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
11577 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
11578 (Write_Overloads): Output the abstract operator if present.
11579 (Add_Entry): Before inserting a new entry into the interpretation table
11580 for a node, determine whether the entry will be disabled by an abstract
11582 (Binary_Op_Interp_May_Be_Hidden): New routine.
11583 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
11585 (Function_Interp_May_Be_Hidden): New routine.
11586 (Has_Compatible_Type): Do not consider interpretations hidden by
11587 abstract operators when trying to determine whether two types are
11589 (Has_Hidden_Interp): New routine.
11590 (Set_May_Be_Hidden_Interp): New routine.
11591 (Write_Overloads): Write the status of flag May_Be_Hidden.

11596 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
11597 types declared in the declarative part of a nested package body or in
11598 the proper body of a stub.
11599 (Set_All_DT_Position): Add missing check to avoid wrong assignation
11600 of the same dispatch table slot to renamed primitives.
11601 (Make_Select_Specific_Data_Table): Handle private types.
11602 (Tagged_Kind): Handle private types.
11603 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
11604 output of implicit importation and exportation.
11605 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11606 first formal of the thunk is always associated with the controlling
11607 type. In addition perform the following code cleanup: remove formal
11608 Thunk_Alias which is no longer required, cleanup evaluation of the
11609 the controlling type, and update the documentation.
11610 Replace occurrence of Default_Prim_Op_Count by
11611 Max_Predef_Prims. Addition of compile-time check to verify
11612 that the value of Max_Predef_Prims is correct.
11613 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11614 (Make_DT): Add parameter to indicate when type has been frozen by an
11615 object declaration, for diagnostic purposes.
11616 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11617 construction of statically allocated dispatch tables.
11618 (Make_DT): In case of library-level tagged types export the declaration
11619 of the primary tag. Remove generation of tags (now done by Make_Tags).
11620 Additional modifications to handle non-static generation of dispatch
11621 tables. Take care of building tables for asynchronous interface types
11622 (Make_Tags): New subprogram that generates the entities associated with
11623 the primary and secondary tags of Typ and fills the contents of Access_
11624 Disp_Table. In case of library-level tagged types imports the forward
11625 declaration of the primary tag that will be declared later by Make_DT.
11626 (Expand_Interface_Conversion): In case of access types to interfaces
11627 replace an itype declaration by an explicit type declaration to avoid
11628 problems associated with the scope of such itype in transient blocks.

11631 Ed Schonberg <schonberg@adacore.com>
11632 Javier Miranda <miranda@adacore.com>
11634 * exp_util.ads, exp_util.adb:
11635 This patch replaces a number of occurrences of explicit tests for N_Null
11636 with calls to Known_Null. This improves tracking of null values, since
11637 Known_Null also catches null constants, and variables currently known to
11638 be null, so we get better tracking.
11639 (Ensure_Defined): create an itype reference only in the scope of the
11641 (Side_Effect_Free): A selected component of an access type that
11642 denotes a component with a rep clause must be treated as not
11643 side-effect free, because if it is part of a linked structure its
11644 value may be affected by a renaming.
11645 (Expand_Subtype_From_Expr): For limited objects initialized with build
11646 in place function calls, do nothing; otherwise we prematurely introduce
11647 an N_Reference node in the expression initializing the object, which
11648 breaks the circuitry that detects and adds the additional arguments to
11649 the called function. Bug found working in the new patch for statically
11650 allocated dispatch tables.
11651 (Is_Library_Level_Tagged_Type): New subprogram.
11652 (Remove_Side_Effects): If the expression of an elementary type is an
11653 operator treat as a function call.
11654 (Make_Literal_Range): If the index type of the array is not integer, use
11655 attributes properly to compute the constraint on the resulting aggregate
11658 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11659 class-wide type whose base type is an incomplete private type, leave
11660 class-wide type unfrozen so that freeze nodes can be generated
11661 properly at a later point.
11662 (Freeze_Entity, array case): Handle case of pragma Pack and component
11663 size attributre clause for same array.
11665 2007-08-14 Vincent Celier <celier@adacore.com>

11720 attribute Body in package Naming. Do not replace a source/unit in the
11721 same project when the order of the source dirs are known. Detect
11722 duplicate sources/units in the same project when the order of the
11723 source dirs are not known.
11724 (Check_Ada_Name): Allow all identifiers that are not reserved words

11730 directory of non extending project to nil.
11731 Change type of path name variables to be Path_Name_Type
11732 (Locate_Directory): Make sure that on Windows '/' is converted to '\',

12287 2007-08-14 Thomas Quinot <quinot@adacore.com>
12289 * table.adb, g-table.adb, g-dyntab.adb (Append): Reimplement in terms
12291 (Set_Item): When the new item is an element of the currently allocated
12292 table passed by reference, save a copy on the stack if we're going
12293 to reallocate. Also, in Table.Set_Item, make sure we test the proper
12294 variable to determine whether to call Set_Last.

12309 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
12310 derived type with interface progenitors use the analyzed formal as the
12311 parent of the actual, to create renamings for all the inherited
12312 operations in Derive_Subprograms.
12313 (Collect_Previous_Instances): new procedure within of
12314 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
12315 unit being loaded, to ensure that the generation of global symbols is
12316 consistent in different compilation modes.
12317 (Is_Tagged_Ancestor): New function testing the ancestor relation that
12318 takes progenitor types into account.
12319 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
12320 traversing over the primitives of the formal and actual types to locate
12321 any abstract subprograms of the actual type that correspond to a
12322 nonabstract subprogram of the formal type's ancestor type(s), and issue
12323 an error if such is found.
12324 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
12325 Instantiate_Package_Body, Instantiate_Subprogram_Body):
12326 Remove bogus guard around calls to Inherit_Context.
12327 (Reset_Entity): If the entity is the selector of a selected component
12328 that denotes a named number, propagate constant-folding to the generic
12329 template only if the named number is global to the generic unit.
12330 (Set_Instance_Env): Only reset the compilation switches when compiling
12331 a predefined or internal unit.
12333 2007-08-14 Ed Schonberg <schonberg@adacore.com>

12336 parameter to determine whether operation applies to the prefix.
12337 (Complete_Object_Operation): If actual has an access type and
12338 controlling formal is not an in_parameter, reject the actual if it is
12339 an access_to_constant type.
12340 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
12341 type, the candidate operations are found in the scope of declaration of
12342 the type, because the type has no primitive subprograms.
12343 (Analyze_Selected_Component): If prefix is class-wide, and root type is
12344 a private extension, only examine visible components before trying to
12345 analyze as a prefixed call.
12346 Change Entity_List to Type_To_Use, for better readability.
12347 (Has_Fixed_Op): Use base type when checking whether the type of an

12353 Ed Schonberg <schonberg@adacore.com>
12355 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
12356 formal At_Any_Place indicating, when True, that we want to test for
12357 availability of the stream attribute at any place (as opposed to the
12358 current visibility context only).
12359 (Missing_Read_Write_Attributes): A stream attribute is missing for the
12360 purpose of enforcing E.2.2(8) only if it is not available at any place.
12361 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
12362 when checking the legality of an extension aggregate in a preelaborable
12363 package. Treat the literal null as a valid default expression in a
12364 component declaration for a type with preelaborable initialization.
12365 A limited interface is a legal progenitor for the designated type of a
12366 remote access to class-wide type.

12378 mark the full view as referenced, to prevent spurious warnings.
12379 (Find_Selected_Component, Has_Components): Handle properly non-limited
12380 views that are themselves incomplete types.
12381 Handle interfaces visible through limited-with clauses.
12382 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
12383 subprogram generic actual for which we have generated a renaming.
12384 Warn when the renaming introduces a homonym of
12385 the renamed entity, and the renamed entity is directly visible.

12388 Hristian Kirtchev <kirtchev@adacore.com>
12390 * sem_res.adb (Resolve_Allocator): Propagate any coextensions that
12391 appear in the subtree to the current allocator if it is not a static
12393 (Resolve_Allocator): Perform cleanup if resolution has determined that
12394 the allocator is not a coextension.
12395 (Resolve): Skip an interpretation hidden by an abstract operator only
12396 when the type of the interpretation matches that of the context.
12397 (Resolve): When looping through all possible interpretations of a node,
12398 do not consider those that are hidden by abstract operators.
12399 (Resolve_Actuals): When verifying that an access to class-wide object
12400 is an actual for a controlling formal, ignore anonymous access to
12401 subprograms whose return type is an access to class_wide type.
12402 (Resolve_Slice): If the prefix of the slice is a selected component
12403 whose type depends on discriminants, build its actual subtype before
12404 applying range checks on the bounds of the slice.
12405 (Valid_Conversion): In an instance or inlined body, compare root types,
12406 to prevent anomalies between private and public views.
12407 (Resolve): Improve error message for ambiguous fixed multiplication
12408 expressions that involve universal_fixed multiplying operations.

12426 extraneous layer of Any wrapping for member label.
12427 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
12428 elabration statements, register the package with the name server
12429 at the beginning, not at the end, of the elaboration statements so
12430 that they can create remote access to subprogram values that designate
12431 remote subprograms from the package.
12433 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
12435 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
12436 values to compute the number of seconds since the Unix Epoc in order to

13576 Ed Schonberg <schonberg@adacore.com>
13577 Robert Dewar <dewar@adacore.com>
13578 Eric Botcazou <ebotcazou@adacore.com>
13579 Arnaud Charlet <charlet@adacore.com>
13581 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
13582 applicable to types that have the With_Type flag set. Returns the
13583 non-limited view of the type, if available, otherwise the type itself.
13584 For class-wide types, there is no direct link in the tree, so we have
13585 to retrieve the class-wide type of the non-limited view of the Etype.
13586 New attributes Static_Initialization and Static_Elaboration_Desired.
13587 Remove the pragma Thread_Body, and the associated flag
13588 Is_Thread_Body in entities, and all related code.
13589 (Suppress_Value_Tracking_On_Call): New flag
13590 E_Exception has Esize and Alignment fields
13591 (Universal_Aliasing): New function.
13592 (Set_Universal_Aliasing): New procedure.
13593 (Write_Entity_Flags): Deal with Universal_Aliasing flag.
13594 (Check_Nested_Access): New procedure.
13595 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
13596 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
13597 (Related_Interface): New attribute. Present in dispatch table pointer
13598 components of records. Set to point to the entity of the corresponding
13600 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
13601 (Original_Access_Type): Remove, not needed.
13602 (Root_Type): Handle properly subtypes of class-wide-types.
13605 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13606 class-wide types visible through limited-with clauses.
13607 (Try_Primitive_Operation): When examining all primitive operations of a
13608 tagged type, do not consider subprograms labeled as hidden unless they
13609 belong to a private generic type with a tagged parent.
13610 (Try_Object_Operation): Extensive rewriting, to handle properly various
13611 overloading cases, when several ancestors may have class-wide operations
13612 that are possible candidates, and when the overloaded functions return
13613 array types and have defaulted parameters so that the call may be
13614 interpreted as an indexing.
13615 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13616 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13617 successive actuals before analyzing the call itself.
13618 (Try_Primitive_Operation): A primitive operation is compatible with the
13619 prefix if the prefix has a synchronized type and the type of the formal
13620 is its corresponding record, as can be the case when the primitive
13621 operation is declared outside of the body of the type.
13622 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13623 perform homonym traversal, looking for class-wide operation matches
13624 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13625 access parameters are now restricted to anonymous access types.
13626 (Mark_Allocator): An allocator with a discriminant association parent is
13628 (Try_One_Prefix_Interpretation): If the type of the object is
13629 incomplete, as can be happen when it is a limited view obtained through
13630 a limited_with_clause, the selected component is not part of a prefixed
13632 (Complete_Object_Operation): Diagnose properly an object that is not
13633 aliased when the corresponding controlling formal is an access
13635 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13636 ambiguous calls in prefixed notation, where two primitives differ only
13637 in that the controlling argument of one is an access parameter.
13639 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13640 whether a function that returns an unconstrained type can be inlined.
13641 (Process_Formals): Diagnose properly the illegal use of an incomplete
13642 type in the profile of an access_to_subprogram declaration.
13643 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13644 operations are attached to the corresponding record.
13645 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13646 When processing a primitive of a concurrent type which implements an
13647 interface change the type of all controlling formals to that of the
13648 corresponding record type.
13649 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13650 to determine the tagged type to which a primitive belongs.
13651 (Check_Conventions): Capture condition to ignore a primitive operation
13652 (which is shared between the loop in Check_Conventions and the one in
13653 Check_Convention) in a new local function Skip_Check.
13654 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13655 confusion with Check_Conventions' own Prim_Op local variable.
13656 (Create_Extra_Formals): Test for a tagged result type rather than a
13657 controlling result when determining whether to add a BIP_Alloc_Form
13658 formal and a BIP_Final_List formal to the function.
13659 (Check_Conformance); For parameters that are anonymous access types,
13660 subtype conformance requires that the not null and the constant
13661 indicators must match
13662 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13663 to retrieve the appropriate type when processing a concurrent type
13664 declared within a generic. Minor comment reformatting. Change invocation
13665 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13667 (Analyze_Subprogram_Body): If the return type of a function is an
13668 anonymous access to the limited view of a class-wide type, and the
13669 non-limited view of the type is available, update the type of the
13670 function so that code can be generated.
13671 (Process_Formals): In case of access-subtype itype whose designated
13672 type is also an itype (situation that happens now with access to
13673 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13674 attribute to avoid backend problems.
13675 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13676 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13677 anonymous types' designated types are same before testing
13678 Subtypes_Statically_Match.
13679 (Create_Extra_Formals): Test for a named access parameter that is a
13680 controlling formal as an additional condition for adding an
13681 accessibility level formal. This can occur in the subp type created for
13682 dispatching calls in Expand_Dispatching_Call, and allows calling
13683 Create_Extra_Formals from that procedure rather than special-casing the
13684 extra formals there.
13685 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13686 when the function has a controlling result.
13687 (Check_Returns): Add much more knowledge of the optimization of local
13688 raise statements to gotos, to retain proper warnings in this case.
13689 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13690 nodes when looking for last statement.
13692 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13693 class-wide types visible through limited with clauses.
13694 (Add_One_Interp): If the operands are anonymous access types, the
13695 predefined operator on universal_access is immediately visibles
13696 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13697 other anonymous access types.
13698 (Disambiguate): Take into account CIL convention.
13699 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13701 2007-06-06 Robert Dewar <dewar@adacore.com>
13703 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13704 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13705 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13706 Fix lower bound of tables.
13709 * nlists.adb: Ditto.
13710 (Prev_Node, Next_Node): Change index type to Int so that it properly
13711 covers the range First_Node_Id - 1 up.
13713 2007-06-06 Javier Miranda <miranda@adacore.com>
13714 Ed Schonberg <schonberg@adacore.com>
13715 Bob Duff <duff@adacore.com>
13716 Hristian Kirtchev <kirtchev@adacore.com>
13718 * exp_aggr.ads, exp_aggr.adb:
13719 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13720 in extension aggregates.
13721 (Flatten): Other conditions being met, an aggregate is static if the
13722 low bound given by component associations is different from the low
13723 bound of the base index type.
13724 (Packed_Array_Aggregate_Handled): If the component type is itself a
13725 packed array or record, the front-end must expand into assignments.
13726 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13727 Init_Pr, instead of Ancestor_Is_Expression.
13728 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13729 coextension chain root, either generate a list controller or use the
13730 already existing one.
13731 (Static_Array_Aggregate): New procedure to construct a positional
13732 aggregate that can be handled by the backend, when all bounds and
13733 components are compile-time known constants.
13734 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13735 types covering interface types into assignments.
13736 (Replace_Type): move to Build_Record_Aggr_Code.
13737 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13738 interface type, convert to the definite type of the aggregate itself,
13739 so that needed components are visible.
13740 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13741 components and the context is an extended return statement do not
13742 create a transient block for it, to prevent premature finalization
13743 before the return is executed.
13744 (Gen_Assign): Do not generate a call to deep adjust routine if the
13745 component type is itself an array of controlled (sub)-components
13746 initialized with an inner aggregate.
13747 (Component_Check): New name for Static_Check. This name is now more
13748 appropriate, and documentation is added which was missing.
13749 (Component_Check): Add test for bit aligned component value
13750 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13751 Tagged_Comps, name is more appropriate given added function below.
13752 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
13754 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13755 Javier Miranda <miranda@adacore.com>
13756 Robert Dewar <dewar@adacore.com>
13758 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13759 Terminated: Add unchecked type conversion from System.Address to
13760 System.Tasking.Task_Id when calling the predefined primitive
13762 Disable new Ada 05 accessibility check for JVM.NET targets, which
13763 cannot be implemented in a practical way.
13764 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13765 the sources always references the tag of the actual object. Therefore,
13766 if 'Tag is applied in the sources to class-wide interface objects we
13767 generate code that displaces "this" to reference the base of the object.
13768 (Expand_N_Attribute_Reference, case Size): Return specified size if
13769 known to front end.
13770 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13771 has code that displaces the pointer of the object to manage interface
13772 types. However this code must not be executed when the prefix is a
13773 subprogram. This bug caused the wrong expansion of the internally
13774 generated assignment that fills the dispatch table when the primitive
13775 is a function returning a class-wide interface type.
13776 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13777 Set_Attribute_Name for Name_Unaligned_Valid.
13779 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13780 Gary Dismukes <dismukes@adacore.com>
13782 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13783 If the initialization is the equivalent aggregate of the initialization
13784 procedure of the type, do not remove it.
13785 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13786 initialized to null from having their expression reset to empty and
13787 note this exception in the comment.
13789 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13790 Robert Dewar <dewar@adacore.com>
13791 Ed Schonberg <schonberg@adacore.com>
13792 Gary Dismukes <dismukes@adacore.com>
13794 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13795 Add "with" and "use" clauses for Sem_Attr.
13796 (Expand_Current_Value): Do not replace occurences of attribute
13797 references where the prefix must be a simple name.
13799 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13800 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13801 Attribute_Requires_Simple_Name_Prefix.
13802 (Name_Modifies_Prefix): Body of new function.
13803 (Requires_Simple_Name_Prefix): Body of new function.
13804 (Resolve_Attribute, case Access): Improve error message for case of
13805 mismatched conventions.
13806 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13808 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13809 constrained subtype for a nominal unconstrained type, use its base type
13810 to check for conformance with the context.
13811 (Resolve_Attribute): Remove test of the access type being associated
13812 with a return statement from condition for performing accessibility
13813 checks on access attributes, since this case is now captured by
13814 Is_Local_Anonymous_Access.
13815 (Analyze_Access_Attribute): Set Address_Taken on entity
13816 (Analyze_Attribute, case Address): Set Address_Taken on entity
13817 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13818 validating an access attribute whose prefix is a current instance.
13819 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13820 applied to dispatching operations, if freezing is required then we set
13821 the attribute Has_Delayed_Freeze in the prefix's entity.
13822 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13823 current scope if access of local subprogram taken
13824 (Analyze_Access_Attribute): Check legality of self-reference even if the
13825 expression comes from source, as when a single component association in
13826 an aggregate has a box association.
13827 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13828 the prefix if it is a protected operation and the attribute is
13829 Unrestricted_Access.
13830 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13831 reference to the base type of the context, to force a constraint check
13832 when the context is an access subtype with an explicit constraint.
13833 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13834 node is rewritten as an interface conversion. leave unanalyzed after
13835 resolution, to ensure that type checking against the context will take

13839 Javier Miranda <miranda@adacore.com>
13840 Robert Dewar <dewar@adacore.com>
13842 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13843 wrapper when the full view of the controlling type of an inherited
13844 function that dispatches on result implements interfaces.
13845 (Expand_N_Object_Declaration): In cases where the type of the
13846 declaration is anonymous access, create finalization list for it.
13847 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13848 if the object has no explicit initialization, to match description of
13849 functionality of pragam Persistent_BSS.
13850 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13851 new function to build static aggregates, to replace initialization call
13852 when static initialization is desired.
13853 (Freeze_Type): Generate a list controller for an access type whenever
13854 its designated type has controlled anonymous access discriminants.
13855 (Build_Equivalent_Aggregate): New procedure to compute a static
13856 aggregate to be used as default initialization for composite types,
13857 instead of a generating a call to the initialization procedure for the
13859 (Build_Initialization_Call): When available, replace a call to the
13860 initialization procedure with a copy of the equivalent static aggregate
13862 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13863 declarations for objects of a class-wide interface type, rather than
13864 just identifiers, to prevent visibility problems.
13865 (Expand_N_Object_Declaration): When expanding the declaration for an
13866 object of a class-wide interface type, preserve the homonym chain of
13867 the original entity before exchanging it with that of the generated
13868 renaming declaration.
13869 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13870 active, because there is no way to handle the exception.
13871 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13872 to do a minimum decoration of the Access_Disp_Table list.
13873 (Expand_Record_Controller): Avoid the addition of the controller between
13874 the component containing the tag of a secondary dispatch table and its
13875 adjacent component that stores the offset to the base of the object.
13876 This latter component is only generated when the parent type has
13877 discriminants ---documented in Add_Interface_Tag_Components).
13878 (Apply_Array_Size_Check): Removed, no longer needed.
13879 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13880 components, create a Master_Entity for it only if it contains tasks.
13881 (Build_Init_Procedure): Suppress the tag assignment compiling under
13883 (Freeze_Record_Type): Remove code associated with creation of dispatch
13885 (Init_Secondary_Tags): Update type of actuals when generating calls to
13886 Ada.Tags.Set_Offset_To_Top
13887 (Stream_Operation_OK): Disable use of streams compiling under no
13889 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13890 if Has_Init_Expression set.
13891 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13892 Register_Primitive, which provides the same functionality.
13893 (Requires_Init_Proc): Return false in case of interface types.
13894 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13896 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13897 is always associated with a predefined primitive because the internal
13898 entities associated with interface types are not predefined primitives.
13899 Therefore, the call to Is_Internal is replaced by a call to the
13900 function Is_Predefined_Dispatching_Operation.
13901 (Make_Eq_If): When generating the list of comparisons for the
13902 components of a given variant, omit the controller component that is
13903 present if the variant has controlled components.
13905 2007-06-06 Javier Miranda <miranda@adacore.com>
13906 Hristian Kirtchev <kirtchev@adacore.com>
13907 Bob Duff <duff@adacore.com>
13909 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13910 handle the creation of finalization lists and calls for nested
13911 coextensions when the root of the chains is part of a return statement.
13912 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13914 (Expand_Record_Equality): Skip components that are interface types.
13915 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13916 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13917 with Rewrite_Coextension. Change the condition for detecting coextension
13919 (Is_Local_Access_Discriminant): Removed.
13920 (Rewrite_Coextension): New routine which rewrites a static coextension
13921 as a temporary and uses its unrestricted access in the construction of
13923 (Complete_Coextension_Finalization): New routine. Generate finalization
13924 attachment calls to all delayed coextensions.
13925 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13926 the allocator is not a coextension itself and has delayed coextensions.
13927 If the current allocator is controlled, but also a coextension, delay
13928 the generation of the finalization attachment call.
13929 Rename local variable "Node" to "Nod" in order to avoid confusion with
13931 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13932 limited types that are not inherently limited. Such an allocator is
13933 illegal, but is generated by the expander for a return statement, to
13934 copy the result onto the secondary stack. This is the only case where a
13935 limited object can be copied. Generate code to displace the pointer
13936 to the object if the qualified expression is a class-wide interface
13937 object. Such displacement was missing and hence the copy of the object
13939 (Apply_Accessibility_Check): Handle allocated objects initialized in
13941 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13942 and Expand_Allocator_Expression. Allocating class-wide interface objects
13943 this routine displaces the pointer to the allocated object to reference
13944 the component referencing the corresponding secondary dispatch table.
13945 Expand_Allocator_Expression): Add missing support to allocate class-wide
13946 interface objects initialized with a qualified expression.
13947 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13948 function result type, and use the finalization list associated with the
13949 function scope in that case (such an anonymous type should not be
13950 treated like an access parameter's type).
13952 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13953 Gary Dismukes <dismukes@adacore.com>
13954 Javier Miranda <miranda@adacore.com>
13956 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13957 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13958 required exception handler.
13959 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13960 properly the case of a function whose return type is a limited
13961 class-wide interface type. Modify the code of the accessibility
13962 check to handle class-wide interface objects. In this case we need to
13963 displace "this" to reference the primary dispatch table to get access
13964 to the TSD of the object (to evaluate its accessibility level).
13965 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13966 rather than a controlling result as one of the conditions for
13967 generating tests of the implicit BIP_Alloc_Form formal. The
13968 initialization assignment is also handled according to whether the
13969 result is tagged instead of controlling.
13970 In the case where the init assignment is inserted in the "then" part of
13971 the allocation conditional, rewrite the target to be a dereference of
13972 the implicit BIP_Object_Access formal.
13973 If the returned value is unconstrained and created on the secondary
13974 stack, mark the enclosing block and function so that the secondary
13975 stack is not reclaimed on return.
13976 Treat returns from functions with controlling results similarly to
13977 returns from functions with unconstrained result subtypes.
13978 If the object returned is unconstrained, and an allocator must be
13979 created for it, analyze the allocator once the block for the extended
13980 return is installed, to ensure that finalizable components
13981 of the expression use the proper finalization list. Guard the call to
13982 Move_Final_List with a check that there is something to finalize.
13983 (Make_Tag_Ctrl_Assignment): Use "old" handling
13984 of controlled type assignment for virtual machines, since new code uses
13985 unsupported features (such as direct access to bytes in memory).
13987 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13988 Ed Schonberg <schonberg@adacore.com>
13990 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13991 accessibility actual, check for the case of an aliased object that has
13992 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13993 we fall into processing for the attribute rather than the name of the
13995 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13996 formal has its address taken in the body, create a temporary to capture
13997 value. If the return type is a limited interface, do not treat the
13998 return value as Controlled.
13999 (Is_In_Place_Function): If the return type is a limited interface,
14000 treat as returning in place. The actual returned object may not always
14001 be limited, but the caller has to assume that it is returned in place.
14002 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
14003 context of an allocator, use the correct finalization chain (that is,
14004 the chain belonging to the access type, rather than the chain belonging
14005 to the current scope).
14006 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
14007 result type rather than a controlling result as a precondition for
14008 adding an allocation form actual to a build-in-place call.
14009 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
14010 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
14011 primitive in the dispatch tables. This work is now done by Make_DT when
14012 the type is frozen.
14013 (Register_Predefined_DT_Entry): Removed.
14014 (Add_Return): If end label is not present, use sloc of last statement
14015 for generated return statement in procedure, for better gdb behavior
14017 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
14018 object address nodes to ensure proper processing by routines like
14020 (Expand_Call): Fix generation of validity check for parameter
14021 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
14022 the allocation form parameter if the result subtype is constrained,
14023 except when the function has a controlling result.
14024 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
14025 rather than Is_Controlled and Has_Controlled_Component, since we want to
14026 include class-wide result types in this treatment. Also test for a
14027 controlling result, since that also requires passing a finalization
14029 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
14030 even when the result subtype is constrained, to handle calls involving
14031 controlling results.
14032 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
14033 is now called even when the result subtype is constrained, to handle
14034 calls involving controlling results.
14035 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
14036 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
14037 now performs the test).
14038 (Make_Build_In_Place_Call_In_Object_Declaration):
14039 Add_Alloc_Form_Actual_* is now called even when the result subtype is
14040 constrained, to handle calls involving controlling results.
14041 (Add_Return): Accomodate rewritten pattern from local raise to goto
14042 transformation, so that we still recognize an transfer statement
14043 and do the right thing here in that case.
14044 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
14045 and end of subprogram code.
14046 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
14047 support for primitives that are functions (without formals) with a
14048 controlling result.
14049 (Inherited_From_Formal): If the actual subtype has not generic parent
14050 type, it is not an actual for a formal derived type, and there is no
14051 operation to inherit from the formal.

14059 exception handler for Deep_Adjust or Deep_Finalize.
14060 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
14061 Raise_From_Controlled_Operation is available, use a call to that
14062 subprogram instead of a plain "raise Program_Error" node to raise
14063 Program_Error if an exception is propagated from an Adjust or Finalize
14065 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
14066 appears in the optional statement list of a triggering alternative, the
14067 scope actions can be inserted directly there, and not in the list that
14068 includes the asynchronous select itself.
14070 2007-06-06 Ed Schonberg <schonberg@adacore.com>
14071 Robert Dewar <dewar@adacore.com>

14096 Nicolas Setton <setton@adacore.com>
14098 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
14099 functionality when the backend is generating code.
14100 Otherwise any serious error
14101 reported by the backend calling the frontend routine Error_Msg
14102 changes the Compilation_Mode to Check_Semantics, disables the
14103 functionality of this routine and causes the generation of
14104 spureous additional errors.
14106 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
14107 debugging information now generated by the compiler for fat-pointer
14109 Document the contents of DW_AT_producer in the GNAT Vendor extensions to

14121 stream attributes of the designated type of an RACW, as they are not
14122 dispatching primitive operations.

14142 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
14143 deallocation of class-wide interface objects.
14144 (Expand_Dispatching_Constructor_Call): Take into account that if the
14145 result of the dispatching constructor is an interface type, the
14146 function returns a class-wide interface type; otherwise the returned
14147 object would be actual. The frontend previously accepted returning
14148 interface types because Expand_Interface_Actuals silently performed
14149 the management of the returned type "as if" it were a class-wide
14151 (Expand_Dispatching_Constructor_Call): Replace call to
14152 Make_DT_Access_Action by direct call to Make_Function_Call.
14154 2007-06-06 Robert Dewar <dewar@adacore.com>
14155 Ed Schonberg <schonberg@adacore.com>
14157 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
14158 compute masking constant, since we now set Esize properly to the
14160 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
14161 to match the alignment.
14162 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
14163 packed arrays of 8 bits or less.
14165 * freeze.adb (Freeze_Entity): When freezing the formals of a
14166 subprogram, freeze the designated type of a parameter of an access type
14167 only if it is an access parameter.

14169 (Freeze_Entity, array type case): Make sure Esize value is properly
14170 adjusted for the alignment if it is known.
14171 (Freeze_Entity, array type case): When checking bit packed arrays for
14172 the size being incorrect, check RM_Size, not Esize.
14173 (Freeze_Record_Type): Check for bad discriminated record convention
14174 (In_Exp_Body): Return true if the body is generated for a subprogram
14175 renaming, either an attribute renaming or a renaming as body.
14176 (Check_Itype): If the designated type of an anonymous access component
14177 is a non-protected subprogram type, indicate that it is frozen, to
14178 prevent out-of-scope freeze node at some subsequent call.
14179 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
14180 only if the subprogram is neither imported nor exported, as well as the

14186 Gary Dismukes <dismukes@adacore.com>
14188 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
14189 default initialization on an imported object, when there is no
14190 initialization call generated for it.

14210 to apply Import to an object renaming declaration.
14212 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
14213 from a C++ class should be declared as limited and that it will be
14214 considererd limited.
14215 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
14216 should be declared as limited and that it will be considererd limited.
14217 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas

14241 object of a limited type can be initialized with a call to a function
14242 that returns in place. If the limited type has unknown discriminants,
14243 and the underlying type is a constrained composite type, build an actual
14244 subtype from the function call, as is done for private types.
14245 (Side_Effect_Free): An expression that is the renaming of an object or
14246 whose prefix is the renaming of a object, is not side-effect free
14247 because it may be assigned through the renaming and its value must be
14248 captured in a temporary.
14249 (Has_Controlled_Coextensions): New routine.
14250 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
14251 as is done for other limited types.

14301 Add new warning for renaming of function return objects
14303 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
14304 (Tree_Read): Use size of object instead of type'object_size, since the
14305 latter is incorrect for packed array types.

14308 * opt.ads: Add new warning for renaming of function return objects
14309 (Generating_Code): New boolean variable used to indicate that the

14321 * sem_ch8.adb (Check_Library_Unit_Renaming): Check that the renamed
14322 unit is a compilation unit, rather than relying on its scope, so that
14323 Standard can be renamed.
14324 (Analyze_Object_Renaming): Add new warning for renaming of function
14326 Also reject attempt to rename function return object in Ada 83 mode.
14327 (Attribute_Renaming): In case of tagged types, add the body of the
14328 generated function to the freezing actions of the type.
14329 (Find_Type): A protected type is visible right after the reserved word
14330 "is" is encountered in its type declaration. Set the entity and type
14331 rather than emitting an error message.

14354 (Configure): New parameter Low_Level_Traces
14355 (Allocate, Deallocation, Free_Physically): Added low-level traces
14356 (Configure): new parameter Errors_To_Stdout.

14358 (Deallocate, Dereference): Send error messages to the proper stream
14359 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
14360 documented. Previous code would send it to the current output file
14361 defined in GNAT.IO, which might not be stdout
14362 (Is_Valid): Adjust comment to mention that a positive reply means that
14363 Header_Of may be used to retrieve the allocation header associated with
14364 the subprogram Storage address argument. Return False early if this
14365 address argument is misaligned.
14367 2007-06-06 Vincent Celier <celier@adacore.com>

14383 Correct error message when invocation of the linker fails
14384 Add explicit size clause for the C imported variables
14385 Object_List_File_Supported and Using_GNU_Linker to emphasize that
14386 we expect char size.
14387 Read target parameters earlier, since this is needed to set
14388 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
14391 2007-06-06 Vincent Celier <celier@adacore.com>
14394 Add 3 spaces before the default project directory when displaying
14395 the project search path.

14424 (Get_Unit): Accept file names x__... and x~... (where x = a, g, i or s)
14425 on all platforms, as it is not possible to know which one is allowed
14426 before processing the project files.
14427 (Check_Stand_Alone_Library): Check that Library_Reference_Symbol_File is
14428 specified when symbol policy is Direct. Check that when there is a

14450 * g-pehage.adb (Produce): Open output files in Binary mode, so that
14451 they have UNIX line endings (LF only) even on Windows, and thus pass
14452 all GNAT style checks.

14774 association, and the corresponding record component has a default
14775 expression, always copy the default expression, even when the

14962 Do_Division_Check flag explicitly.
14963 (Resolve_Actuals): If the actual is of a synchronized type, and the
14964 formal is of the corresponding record type, this is a call to a
14965 primitive operation of the type, that is declared outside of the type;
14966 the actual must be unchecked-converted to the type of the actual
14967 (Resolve_Call): Kill all current values for any subprogram call if

15875 parameter, rewrite the call as the indexing of a call with a single
15876 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15878 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15879 the master of the created object is the innermost enclosing statement.
15880 (Remove_Conversions): For a binary operator, check if type of second
15881 formal is numeric, to check if an abstract interpretation is present

16073 Remove no longer used entities.
16075 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no

16123 attempt to derive from a synchronized tagged type.

16128 that use (a subtype of) the class-wide type of the enclosing type.
16129 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass

16131 Check_Anonymous_Access_Components rather than Empty.
16132 (Make_Incomplete_Type_Declaration): Add test for case where the type has
16133 a record extension in deciding whether to create a class-wide type,

16214 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
16215 when -gnatg is not specified.
16216 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because

16246 discriminant and the type is controlled. do not place on a finalization
16247 list at this point. The proper list will be determined from the
16249 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
16250 initialize record controller if needed, before the components, to ensure
16251 that they are properly finalized.
16252 (Build_Record_Aggr_Code): For the case of an array component that has a
16253 corresponding array aggregate in the record aggregate, perform sliding

16264 accessibility on class-wide allocators if the allocator occurs at the
16265 same scope level as the allocator's type. The check is guaranteed to
16266 succeed in that case, even when the expression originates from a
16267 parameter of the containing subprogram.
16268 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
16269 under No_Dispatching_Calls restriction. During the semantic analysis
16270 we already notified such violation.
16271 (Tagged_Membership): Constant folding. There is no need to check
16272 the tag at run-time if the type of the right operand is non
16273 class-wide abstract.
16274 Replace call to Is_Ancestor by call to Is_Parent
16275 to support concurrent types with interface types.
16276 (Expand_N_Allocator): Add an assertion associated with the generation

16287 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
16288 initialize most the TSD components by means of an aggregate.
16289 Modify the declaration of the object containing the TSD
16290 because we now expand code that has a higher level of abstraction.
16291 The TSD has a discriminant containing the Inheritance Depth Level,
16292 value that is used in the membership test but also to fix the size
16293 of the table of ancestors.
16294 (Expand_Interface_Conversion): Insert function body at the closest place
16295 to the conversion expression, to prevent access-before-elaboration
16296 errors in the backend.

16298 compiling under restriction No_Dispatching_Calls plus code cleanup.
16299 Code reorganization plus removal of calls to Set_Num_Prim_Ops
16300 (Make_Secondary_DT): Remove call to Set_Num_Prim_Ops.
16301 (Expand_Dispatching_Call): Minor code reorganization plus addition of
16302 code to return immediately if compiling under No_Dispatching_Calls

16321 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
16322 (Expand_Dispatching_Call): Replace generation of call to the run-time
16323 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
16324 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
16326 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
16327 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
16328 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
16329 Build_Set_Prim_Op_Address.
16330 (Get_Remotely_Callable): Subprogram removed.
16331 (Init_Predefined_Interface_Primitives): Replace generation of call to
16332 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
16335 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
16336 First (Parameter_Associations ()) with the call to First_Actual that
16337 returns an actual parameter expression for both named and positional
16340 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
16341 check violation of restriction No_Dispatching_Calls.
16342 (Check_Controlling_Type): A formal of a tagged incomplete type is a
16343 controlling argument.

16346 First/Next_Component_Or_Discriminant
16347 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
16348 (Find_Implemented_Interface): Removed. All the calls to this subprogram
16349 specify Any_Limited_Interface, and this functionality is already
16350 provided by the function Has_Abstract_Interfaces.
16351 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
16352 support concurrent types implementing interfaces.
16353 (Find_Implemented_Interface): Removed. All the calls to this subprogram
16354 specify kind Any_Limited_Interface, and this functionality is already
16355 provided by the function Has_Abstract_Interfaces.
16356 (Remove_Side_Effects): replace Controlled_Type by
16357 CW_Or_Controlled_Type whenever the issue is related to
16358 using or not the secondary stack.
16360 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
16361 P_Interface_Type_Definition to fulfill the new interface (the formal
16362 Is_Synchronized is no longer required).
16364 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
16365 Update dependencies.

16373 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
16374 anonymous, use finalization list of enclosing dynamic scope.
16375 (Expand_N_Package_Declaration): For a library package declaration
16376 without a corresponding body, generate RACW subprogram bodies in the
16377 spec (just as we do for the task activation call).
16378 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
16379 Is_Abstract_Type. Make sure these are called only when appropriate.
16380 Remove all code for DSP option
16381 (CW_Or_Controlled_Type): new subprogram.

16387 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
16388 parameter. If it is set to true, return a result capped according to
16389 the global upper bound for the index of an entry family.
16390 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
16391 (Build_Find_Body_Index): Adjust for above change.
16392 (Entry_Index_Expression): Likewise.
16393 (Is_Potentially_Large_Family): New function extracted from...
16394 (Collect_Entry_Families): ...here. Call it to detect whether the family
16395 is potentially large.
16396 (Build_Entry_Count_Expression): If the family is potentially large, call
16397 Family_Size with 'Cap' set to true.
16398 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
16399 a protected version of an operation declared in the private part of
16400 a protected object, because they may be invoked through a callback.
16401 (Set_Privals): If the type of a private component is an anonymous access
16402 type, do not create a new itype for each protected body.
16403 If the body of a protected operation creates
16404 controlled types (including allocators for class-widetypes), the
16405 body of the corresponding protected subprogram must include a
16407 (Build_Activation_Chain_Entity): Build the chain entity for extended
16409 (Type_Conformant_Parameters): Use common predicate Conforming_Types
16410 to determine whether operation overrides an inherited primitive.
16411 (Build_Wrapper_Spec): Add code to examine the parents while looking
16412 for a possible overriding candidate.
16413 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
16414 hold an actual parameter value since its initialization is separated
16415 from the the declaration. Prevents errors on null-excluding access
16418 2007-04-06 Thomas Quinot <quinot@adacore.com>
16419 Pablo Oliveira <oliveira@adacore.com>
16421 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
16422 Do an Unchecked_Conversion to handle the passage from the Underlying
16423 Type to the Base Type when calling Build_To_Any_Call and
16424 Build_From_Any_Call.
16425 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
16426 E_Constant, depending upon Variable formal.
16427 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
16428 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
16429 parameter that requires an extra constrained parameter, declare
16430 temporary for actual as a variable, not a constant.
16431 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
16432 the unit being compiled is the one that contains the stub type.
16433 Change primitive operation name for the RACW associated with a RAS
16434 from Call to _Call so it cannot clash with any legal identifier.
16435 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
16437 (Append_RACW_Bodies): New subprogram.
16438 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
16439 Add_Receiving_Stubs_To_Declarations functions.
16440 When expanding a package body, this list correspond to the
16441 statements in the HSS at the end of the pacakge.
16442 When expanding a package spec, this list correspond to the

16445 registering the receiving stubs at the end of the 'Stmts' list.
16446 (RCI_Package_Locator): Pass the new Version generic formal when
16447 instantiating a RCI_Locator package.
16448 (Build_From_Any_Function): To compute the High bound for an
16449 unconstrained array actual, we add the Low bound with the length.
16450 Thus we must convert the low bound and the length to an appropriate
16451 type before doing the sum.
16452 (Build_Subprogram_Receiving_Stubs, PolyORB):
16453 * Retrieve the extra formals parameters at the
16454 end of the parameter stream.
16455 * Use Move_Any_Value to write back out parameters
16456 after executing the request as it is more efficient
16457 than Copy_Any_Value.
16458 * Build the any containing Extra Formals with the
16459 appropriate typecode.
16460 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
16461 empty Component_List.
16462 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
16463 the tree the declaration for an object that serves as actual parameter
16464 in server-side stubs.

16474 function with the first not implicit parent type.
16475 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
16476 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
16477 typecode from the Etype. Therefore we retrieve the correct typecode
16478 with a call to Get_Any_Type.
16479 (Copy_Specification): Do controlling formal type substitution based on
16480 Is_Controlling_Formal flag, instead of caller-provided object type.
16481 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
16482 a RACW primitive operation, we might get a subprogram declaration for an
16483 ancestor of the RACW designated type (not for the designated type
16484 itself), in the case where this operation is inherited. In this case we
16485 have no easy means of determining the original tagged type for which
16486 the primitive was declared, so instead we now rely on
16487 Copy_Specification to use the Is_Controlling_Formal flag to determine
16488 which formals require type substitution.

16494 GNAT.Current_Exception are not allowed if pragma Restrictions
16495 (No_Exception_Propagation) is set and in any case make the associated
16496 handler unsuitable as a target for a local raise statement.
16497 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
16498 run-time subprogram CW_Membership by call to Build_CW_Membership.
16499 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
16500 by a function call, a temporary must be created before expanding the
16501 Constructor_Call itself, to prevent out-of-order elaboration in the
16502 back-end when stack checking is enabled..
16504 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16506 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
16507 result are the bounds of the left operand, not the right.
16509 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16512 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

16629 * mingw32.h (S2WSU): New macro to convert from a string to a
16630 wide-string using the UTF-8 encoding. The S2WS macro supports now only
16631 standard 8bits encoding.
16632 (WS2SU): As above but converting from wide-sring to string.
16633 This is needed as it is necessary to have access to both versions in the
16634 runtime for the form parameter encoding support.
16635 This set of patch add support for the encoding form parameter.
16636 (S2WS): Improve implementation to handle cases where the filename is not
16637 UTF-8 encoded. In this case we default to using the current code page
16638 for the conversion.
16640 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
16641 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

16650 corresponding encoding value into AFCB structure.
16651 (Reset): Pass the encoding value to freopen.

16688 implementation of floating point operations as native x86 targets.
16689 So the FPU should be initialized in the same way using finit. Fix
16690 floating point operations accuracy issues.
16691 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
16692 member in struct sigaction, so as to avoid warning for incompatible

16708 Javier Miranda <miranda@adacore.com>
16710 * lib-xref.ads, lib-xref.adb:
16711 Modify the loop that collects type references, to include interface
16712 types that the type implements. List each of these interfaces when
16713 building the entry for the type.
16714 (Generate_Definition): Initialize component Def and Typ of new entry
16715 in table Xrefs, to avoid to have these components unitialized.
16716 (Output_References): Split Is_Abstract flag into
16717 Is_Abstract_Subprogram and Is_Abstract_Type.
16718 (Generate_Reference): Add barrier to do not generate the warning
16719 associated with Ada 2005 entities with entities generated by the

16759 2007-04-06 Robert Dewar <dewar@adacore.com>
16761 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16762 it no longer destroys the contents of Name_Buffer or Name_Len and
16763 non-standard and invalid names are handled better.
16764 (Get_Decoded_Name_String): Improve performance by using
16765 Name_Has_No_Encodings flag in the name table.
16766 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
16767 Used for debugging printouts.

16771 Bob Duff <duff@adacore.com>
16773 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16774 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16775 there is no need to generate always a record_definition_node in case
16776 of synchronized interface types.
16777 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16778 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16779 illegal in Ada 95, in cases where it is legal. Change the warnings to
16780 errors in other cases. Don't give the error unless the "not null"
16781 parses properly. Correct the source position at which the error occurs.
16782 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16783 P_Null_Exclusion, to suppress "not null" warnings.

16835 Entry for pragma Unreferenced_Objects
16837 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
16838 switches, without repetition of "eD". Make sure that last character of
16839 -gnatep= switch is not taken as -gnat switch character.
16840 Complete rewrite of circuit for handling saving compilation options

16859 the default project path, initially done during elaboration of the
16861 If the prefix returned by Sdefault is null, get the prefix from a call
16862 to Executable_Prefix_Path.
16863 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16866 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16867 canonical directory name to open the directory from which files are
16869 (Record_Other_Sources): Idem.
16870 (Locate_Directory): Add the possibility to create automatically missing
16871 directories when Setup_Projects is True.
16872 Call Locate_Directory so that the directory will be created when
16873 Setup_Projects is True, for object dir, library dir, library ALI dir,
16874 library source copy dir and exec dir.
16876 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16879 2007-04-06 Robert Dewar <dewar@adacore.com>

16914 full word is no longer compared twice.
16916 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16918 * sem_ch10.adb (Install_Limited_Context_Clauses.
16919 Expand_Limited_With_Clause): Use a new copy of selector name in the
16920 call to Make_With_Clause. This fixes the tree structure for ASIS
16921 purposes. Nothing is changed in the compiler behaviour.
16922 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16923 a package renaming.
16924 (Install_Limited_With_Clauses): Do not install non-limited view when it
16925 is still incomplete.
16927 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16928 Gary Dismukes <dismukes@adacore.com>
16930 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16931 when capturing size information, instead of base type, which for a
16932 formal array type will be the unconstrained type.
16933 (Analyze_Formal_Object_Declaration): Add check for illegal default
16934 expressions for a formal in object of a limited type.
16935 (Instantiate_Object): Ditto.
16936 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16937 because they were defaulted in the formal package and no check applies
16939 (Check_Formal_Package_Instance): Extend conformance check to other
16940 discrete types beyond Integer.
16941 (Process_Default): Copy directly the unmatched formal. A generic copy
16942 has already been performed in Analyze_Formal_Package.
16943 (Analyze_Associations): If a formal subprogram has no match, check for
16944 partial parametrization before looking for a default, to prevent
16946 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16947 not set the instantiation environment before analyzing the actuals.
16948 Fixes regression on 8515-003 with implementation of AI-133.
16949 Set_Instance_Env checks whether the generic unit is a predefined
16950 unit, in which case the instance must be analyzed with the latest Ada
16951 mode. This setting must take place after analysis of the actuals,
16952 because the actuals must be analyzed and frozen in the Ada mode extant
16953 outside of the current instantiation.
16954 (Save_Env, Restore_Env): Preserve and restore the configuration
16955 parameters so that predefined units can be compiled in the proper Ada
16957 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16958 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16959 and Is_Abstract_Type.
16960 (Analyze_Formal_Package): For better error recovery, Add exception
16961 handler to catch Instantion_Error, which can be raised in
16962 Analyze_Associations
16964 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16965 Bob Duff <duff@adacore.com>
16966 Gary Dismukes <dismukes@adacore.com>
16968 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16969 prefix type is a discriminated subtype of the type of the formal.
16970 (Analyze_Allocator): Collect all coextensions regardless of the context.
16971 Whether they can be allocated statically is determined in exp_ch4.
16972 (Analyze_Selected_Component): If the prefix is a limited view and the
16973 non-limited view is available, use the non-limited one.
16974 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16975 therefore illegal), suggest a qualified expression rather than a type
16976 conversion, because a type conversion would be illegal in this context.
16977 (Anayze_Allocator): Trace recursively all nested allocators so that all
16978 coextensions are on the corresponding list for the root. Do no mark
16979 coextensions if the root allocator is within a declaration for a stack-
16980 allocated object, because the access discriminants will be allocated on
16982 (Analyze_Call): Remove restriction on calls to limited functions for the
16983 cases of generic actuals for formal objects, defaults for formal objects
16984 and defaults for record components.
16985 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16986 element list. Their expansion is delayed until the enclosing allocator
16987 is processed and its finalization list constructed.
16988 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16989 for an operation with the given name among the primitive operations of
16990 the corresponding record type.
16991 (Analyze_Selected_Component): If the prefix is a task type that
16992 implements an interface, and there is no entry with the given name,
16993 check whether there is another primitive operation (e.g. a function)
16995 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16996 properly the indexing of a function call written in prefix form, where
16997 the function returns an array type, and all parameters of the function
16998 except the first have defaults.
16999 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
17000 the original operands, rather than relocating them, for efficiency and
17001 to work properly when an operand is overloaded.
17002 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
17003 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
17004 (Analyze_Selected_Component): If the prefix is a private extension, only
17005 scan the visible components, not those of the full view.
17006 (Try_Primitive_Operation): If the operation is a procedure, collect all
17007 possible interpretations, as for a function, because in the presence of
17008 classwide parameters several primitive operations of the type can match
17009 the given arguments.
17011 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17012 Robert Dewar <dewar@adacore.com>
17014 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
17015 tag-indeterminate call to an abstract function, when the left-hand side
17017 (Analyze_Loop_Statement): Improve detection of infinite loops
17019 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17020 Thomas Quinot <quinot@adacore.com>
17022 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
17023 out of Analyze_Package_Declaration, because processing must be applied
17024 to package bodies as well, for deferred constants completed by pragmas.
17025 (Analyze_Package_Declaration): When the package declaration being
17026 analyzed does not require an explicit body, call Check_Completion.
17027 (May_Need_Implicit_Body): An implicit body is required when a package
17028 spec contains the declaration of a remote access-to-classwide type.
17029 (Analyze_Package_Body): If the package contains RACWs, append the
17030 pending subprogram bodies generated by exp_dist at the end of the body.
17031 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
17032 Is_Abstract_Subprogram and Is_Abstract_Type.
17033 (Preserve_Full_Attributes): The full entity list is not an attribute
17034 that must be preserved from full to partial view.
17036 * sem_dist.adb (Add_RAS_Dereference_TSS):
17037 Change primitive name to _Call so it cannot clash with any legal
17038 identifier, and be special-cased in Check_Completion.
17039 Mark the full view of the designated type for the RACW associated with
17040 a RAS as Comes_From_Source to get proper view switching when installing
17041 private declarations.
17042 Provite a placeholder nested package body along with the nested spec
17043 to have a place for Append_RACW_Bodies to generate the calling stubs
17044 and stream attributes.
17046 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17047 Robert Dewar <dewar@adacore.com>
17049 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
17050 that is a limited view, check the non-limited view if available.
17051 (Undefined): Refine error message for missing with of Text_IO
17052 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
17053 to distinguish real missing with cases.
17054 Fix format of all missing with messages
17055 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
17056 renaming as body when renamed entity is abstract.
17058 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17059 Javier Miranda <miranda@adacore.com>
17061 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make

17070 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17071 Javier Miranda <miranda@adacore.com>
17073 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
17074 dereference of a local object R created as a reference to another
17075 object O, use the access level of O.
17076 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
17077 rather than local Same_Formal_Type, to check whether protected operation
17078 overrides an inherited one.
17079 (Same_Formal_Type): New predicate, used when matching signatures of
17080 overriding synchronized operations, to handle the case when a formal
17081 has a type that is a generic actual.
17082 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
17083 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
17084 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
17085 syntactic ambiguities involving indexing of function calls that return
17087 (Abstract_Interface_List): New subprogram that returns the list of
17088 abstract interfaces associated with a concurrent type or a
17089 concurrent record type.
17090 (Interface_Present_In_Parent): New subprogram used to check if a
17091 given type or some of its parents implement a given interface.
17092 (Collect_Abstract_Interfaces): Add support for concurrent types
17093 with interface types.
17094 (Has_Abstract_Interfaces): Add support for concurrent types with
17096 (Is_Parent): New subprogram that determines whether E1 is a parent
17097 of E2. For a concurrent type its parent is the first element of its
17098 list of interface types; for other types this function provides the
17099 same result than Is_Ancestor.
17100 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
17101 (Collect_Synchronized_Interfaces): Removed because the subprogram
17102 Collect_Abstract_Interfaces provides this functionality.
17103 (Collect_Abstract_Interfaces): Minor update to give support to
17104 concurrent types and thus avoid undesired code duplication.
17105 (Get_Subprogram_Entity): Handle entry calls.
17106 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
17108 (Enter_Name): Do not give -gnatwh hiding warning for record component
17109 entities, they never result in hiding.

17112 Robert Dewar <dewar@adacore.com>
17114 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,
17115 to chain nested components that are allocators for access discriminants
17116 of the enclosing object.
17117 Add N_Push and N_Pop nodes
17118 New field Exception_Label added
17119 (Local_Raise_Statements): New field in N_Exception_Handler_Node
17120 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

17124 can be an E_Return_Statement.
17125 (Is_Coextension): New flag for allocators.

17133 * s-tpobop.adb (Exceptional_Complete_Entry_Body): Undefer abortion
17134 before propagating exception.
17136 2007-04-06 Olivier Hainque <hainque@adacore.com>
17138 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
17139 an address always within the call instruction from a return address.

17144 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
17145 expression with a COMPOUND_EXPR including the call instead of emitting
17146 the call directly here.
17147 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the

17439 anonymous access types.
17440 (Valid_Conversion): For a conversion to a numeric type occurring in an
17441 instance or inlined body, no need to check that the operand type is
17442 numeric, since this has been checked during analysis of the template.

18031 assignments where the target subtype is unconstrained and the target
18032 object is a parameter or dereference (other aliased cases are known
18033 to be unconstrained).

18148 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
18149 are build-in-place function calls.
18150 (Replace_Self_Reference): New subsidiary of
18151 Make_OK_Assignment_Statement, to replace an access attribute that is a
18152 self-reference into an access to the appropriate component of the
18153 target object. Generalizes previous mechanism to handle self-references
18154 nested at any level.
18155 (Is_Self_Referential_Init): Remove, not needed.
18156 (Is_Self_Referential_Init): New predicate to simplify handling of self
18157 referential components in record aggregates.

18159 check for presence of entity before checking for self-reference.
18160 (Has_Default_Init_Comps): Return True if a component association is a
18161 self-reference to the enclosing type, which can only come from a
18162 default initialization.
18163 (Make_OK_Assignment_Statement): If the expression is of the form
18164 Typ'Acc, where Acc is an access attribute, the expression comes from a
18165 default initialized self-referential component.
18166 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
18167 that has been derived from several abstract interfaces we must also
18168 initialize the tags of the secondary dispatch tables.

18173 Robert Dewar <dewar@adacore.com>
18176 (Expand_Access_To_Protected_Op): If the context indicates that an access
18177 to a local operation may be transfered outside of the object, create an
18178 access to the wrapper operation that must be used in an external call.
18179 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
18180 target, pass the Valid attribute applied to a floating-point prefix on
18181 to the back end without expansion.
18182 (Storage_Size): Use the new run-time function Storage_Size to retrieve
18183 the allocated storage when it is specified by a per-object expression.
18184 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
18185 Nothing to do here, the attribute has been rewritten during semantic

18194 into a fat pointer.
18195 (Is_Constrained_Aliased_View): New predicate to help determine whether a
18196 subcomponent's enclosing variable is aliased with a constrained subtype.
18197 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
18198 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
18199 an aliased prefix must be known to be constrained in order to use True
18200 for the attribute value, and now it's possible for some aliased views
18201 to be unconstrained.
18203 2006-10-31 Robert Dewar <dewar@adacore.com>
18205 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue

18214 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
18215 register in the final list objects containing class-wide interfaces;
18216 otherwise we incorrectly register the tag of the interface in the final
18218 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
18219 generate the wrapper if the parent primitive is abstract. This is
18220 required to report the correct error message.
18221 (Expand_N_Subtype_Indication): Do validity checks on range
18222 (Clean_Task_Names): If an initialization procedure includes a call to
18223 initialize a task (sub)component, indicate that the procedure will use
18224 the secondary stack.
18225 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
18226 compatibility for interfacing with CPP by default.
18227 (Expand_N_Object_Declaration): Only build an Adjust call when the
18228 object's type is a nonlimited controlled type.
18229 * exp_ch3.adb: Add with and use of Exp_Ch6.
18230 (Expand_N_Object_Declaration): Check for object initialization that is a
18231 call to build-in-place function and apply Make_Build_In_Place_Call_In_
18232 Object_Declaration to the call.
18233 (Freeze_Type): When the designated type of an RACW was not frozen at the
18234 point where the RACW was declared, validate the primitive operations
18235 with respect to E.2.2(14) when it finally is frozen.
18236 (Build_Initialization_Call,Expand_Record_Controller): Rename
18237 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
18238 return-by-reference has no meaning in Ada 2005.
18239 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
18240 to register tag of the immediate ancestor interfaces in the
18241 run-time structure.

18243 initialization of extension aggregates with abstract interfaces.
18244 (Build_Master_Renaming): Make public, for use by function declarations
18245 whose return type is an anonymous access type.
18246 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
18247 Insert_List_Before_And_Analyze after the generation of the specs
18248 associated with null procedures.
18249 (Expand_Tagged_Root): Update documentation in its specification.
18250 (Init_Secondary_Tags): Update documentation.
18251 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
18252 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
18253 then generate code to inherit the contents of the dispatch table
18254 directly from the ancestor.
18255 (Expand_Record_Controller): Insert controller component after tags of
18256 implemented interfaces.
18257 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
18258 create null procedure overridings when null procedures are inherited

18261 declarations for overriding null primitives inherited from interfaces.
18262 (Is_Null_Interface_Procedure): New function in
18263 Make_Null_Procedure_Specs.
18264 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
18265 immediate ancestor of a tagged type is an abstract interface type we
18266 must generate the specification of the predefined primitives associated
18267 with controlled types (because the dispatch table of the ancestor is
18268 null and hence these entries cannot be inherited). This is required to
18269 elaborate well the dispatch table.

18279 (Expand_N_In): Do validity checks on range
18280 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
18281 (Expand_N_Allocator): For "new T", if the object is constrained by
18282 discriminant defaults, allocate the right amount of memory, rather than
18283 the maximum for type T.
18284 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
18285 when the allocator is initialized by a build-in-place call, since the
18286 allocator is already rewritten as a reference to the function result,
18287 and this prevents an unwanted duplication of the function call.
18288 Add with and use of Exp_Ch6.
18289 (Expand_Allocator_Expresssion): Check for an allocator whose expression
18290 is a call to build-in-place function and apply
18291 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
18292 untagged designated types).
18293 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
18294 optimization if source or target is biased.
18295 (Expand_N_Allocator): Add comments for case of an allocator within a
18296 function that returns an anonymous access type designating tasks.
18297 (Expand_N_Allocator): apply discriminant checks for access
18298 discriminants of anonymous access types (AI-402, AI-416)

18307 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
18308 (Expand_N_Assignment_Statement): Call
18309 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
18310 build-in-place function call. Currently, this can happen only for
18311 assignments that come from aggregates.
18312 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18313 in order to alleviate the upward compatibility introduced by AI-318.
18314 (Expand_N_Extended_Return_Statement): Add support for handling the
18315 return object as a build-in-place result.
18316 (Expand_Non_Function_Return): Implement simple return statements nested
18317 within an extended return.
18318 (Enable_New_Return_Processing): Turn on the new processing of return
18320 (Expand_Non_Function_Return): For a return within an extended return,
18321 don't raise Program_Error, because Sem_Ch6 now gives a warning.
18322 (Expand_N_Extended_Return_Statement): Implement AI-318
18323 (Expand_Simple_Function_Return): Ditto.
18324 (Expand_N_If_Statement): Handle new -gnatwt warning

18326 (Expand_N_Assignment): Handle assignment to the Priority attribute of
18327 a protected object.
18328 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
18329 validity checking of assignments to elementary record components.
18330 (Expand_N_Return_Statement): return Class Wide types on the secondary
18331 stack independantly of their controlled status since with HIE runtimes,
18332 class wide types are not potentially controlled anymore.
18334 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
18337 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
18338 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
18339 it expects a block, procedure, or task. The return statement will get
18340 turned into a block, and Expand_Cleanup_Actions will happen then.

18344 Bob Duff <duff@adacore.com>
18345 Gary Dismukes <dismukes@adacore.com>
18347 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
18349 (Expand_Inlined_Call): Tagged types are by-reference types, and
18350 therefore should be replaced by a renaming declaration in the expanded
18351 body, as is done for limited types.
18352 (Expand_Call): If this is a call to a function with dispatching access
18353 result, propagate tag from context.
18354 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
18356 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
18357 build-in-place when the right-hand side of an assignment is a
18358 build-in-place function call.
18359 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
18360 of the explicit dereference of the allocator to the result subtype of
18361 the build-in-place function. This is needed to satisfy type checking
18362 in cases where the caller's return object is created by an allocator for
18363 a class-wide access type and the type named in the allocator is a
18365 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
18366 conversion of the reference to the declared object to the result subtype
18367 of the build-in-place function. This is needed to satisfy type checking
18368 in cases where the declared object has a class-wide type. Also, in the
18369 class-wide case, change the type of the object entity to the specific
18370 result subtype of the function, to avoid passing a class-wide object
18371 without explicit initialization to the back end.
18372 (Register_Interface_DT_Entry): Moved outside the body of
18373 Freeze_Subprogram because this routine is now public; it is called from
18374 Check_Dispatching_Overriding to handle late overriding of abstract
18375 interface primitives.
18376 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
18377 adding an implicit access actual on a call to a build-in-place function.

18379 build-in-place function and apply
18380 Make_Build_In_Place_Call_In_Anonymous_Context to the call.

18382 entity is a function whose calls should be handled as build-in-place.
18383 (Is_Build_In_Place_Function_Call): New function to determine whether an
18384 expression is a function call that should handled as build-in-place.
18385 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
18386 calls to build-in-place functions as the initialization of an allocator.
18387 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
18388 handling calls to build-in-place functions in contexts that do not
18389 involve init of a separate object (for example, actuals of subprogram
18391 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
18392 handling calls to build-in-place functions as the initialization of an
18393 object declaration.

18395 instantiation of Traverse_Body to avoid unreferenced warning.
18396 (Check_Overriding_Inherited_Interfaces): Removed.
18397 (Register_Interface_DT_Entry): Code cleanup.
18398 (Register_Predefined_DT_Entry): Code cleanup.
18399 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
18400 inlined statements if within a transient scope.
18401 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
18402 formal parameters with occurrences of actuals in inlined body, establish
18403 visibility on the proper view of the actual's subtype for the body's
18405 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
18406 compatibility mode and we have an imported CPP subprogram because
18407 for now we assume that imported CPP primitives correspond with
18408 objects whose constructor is in the CPP side (and therefore we
18409 don't need to generate code to register them in the dispatch table).
18410 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
18411 aligned selected component.
18412 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
18413 the actual of an in-mode parameter is a type conversion.
18414 (Expand_Actuals): If the call does not come from source and the actual
18415 is potentially misaligned, let gigi handle it rather than rejecting the
18416 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
18417 Class Wide types as returning by reference independantly of their
18418 controlled status since with HIE runtimes class wide types are not
18419 potentially controlled anymore.

18424 references that are private components of the protected object.

18426 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
18427 instantiation to deal with warnings.

18434 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
18435 initialization of Homonym_Len.
18436 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
18437 names from fully qualified name. Fixes problem of duplicate
18438 external names differing only in the presence of such a block name.

18441 Pablo Oliveira <oliveira@adacore.com>
18443 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
18444 subprogram Ids, even if they are not yet assigned.
18445 (Build_Subprogram_Id): It is now this function that will take care of
18446 calling Assign_Subprogram_Ids if necessary.
18447 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
18448 should be done only once they are assigned.
18449 (Build_From_Any_Function, case of tagged types): Add missing call to

18452 type for an RACW type.
18453 (Add_RACW_Features): When processing an RACW declaration for which the
18454 designated type is already frozen, enforce E.2.2(14) rules immediately.
18455 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
18456 special reordering of controlling formals.
18458 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the

18461 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18463 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
18464 fixed-point operations in an integer context, i.e. as operands of a
18465 conversion to an integer type, indicate that result must be rounded.
18467 2006-10-31 Robert Dewar <dewar@adacore.com>
18469 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
18470 cases, pass the encoding method, since it is now required by the run
18473 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
18474 assumption that Str'First = 1.
18475 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
18476 it on to the Value_Wide_Wide_Character call.
18477 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
18478 properly handles a string of the form quote-encoded_wide_char-quote.
18480 * s-wchcnv.adb: Minor reformatting
18482 2006-10-31 Javier Miranda <miranda@adacore.com>
18484 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
18485 run-time membership test to ensure that the constructed object
18486 implements the target abstract interface.
18488 2006-10-31 Robert Dewar <dewar@adacore.com>
18490 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
18491 Machine_Attribute pragma internally to implement the user pragma.
18492 Add processing for pragma Interface so that it is now completely
18493 equivalent to pragma Import.
18495 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
18496 so that it can be applied to all entities, including record components
18497 and enumeration literals.
18498 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
18499 priority ranges are correct, verify compatibility against task
18500 dispatching and locking policies, and if everything is correct an entry
18501 is added to the table containing priority specific dispatching entries
18502 for this compilation unit.
18503 (Delay_Config_Pragma_Analyze): Delay processing
18504 Priority_Specific_Dispatching pragmas because when processing the
18505 pragma we need to access run-time data, such as the range of
18506 System.Any_Priority.
18507 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
18508 Allow pragma Unreferenced as a context item
18509 Add pragma Preelaborable_Initialization
18510 (Analyze_Pragma, case Interface): Interface is extended so that it is
18511 now syntactically and semantically equivalent to Import.
18512 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
18513 insertion characters.
18514 Add handling for Pragma_Wide_Character_Encoding
18515 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
18516 never supercedes a real restriction, and that a real restriction
18517 always supercedes a warning.
18518 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
18521 2006-10-31 Bob Duff <duff@adacore.com>
18522 Ed Schonberg <schonberg@adacore.com>
18523 Robert Dewar <dewar@adacore.com>
18525 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
18526 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
18527 Is_Inherently_Limited_Type, because return-by-reference has no meaning
18529 (Find_Node_To_Be_Wrapped): Use new method of determining the result
18530 type of the function containing a return statement, because the
18531 Return_Type field was removed. We now use the Return_Applies_To field.
18533 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
18534 (Build_Task_Image_Decl): If procedure is not called from an
18535 initialization procedure, indicate that function that builds task name
18536 uses the sec. stack. Otherwise the enclosing initialization procedure
18537 will carry the indication.
18538 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
18539 N_Object_Declaration instead.
18540 (Kill_Dead_Code): New interface to implement -gnatwt warning for
18541 conditional dead code killed, and change implementation accordingly.
18542 (Insert_Actions): Add N_Return_Object_Declaration case.
18543 Correct comment to mention N_Extension_Aggregate node.
18544 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
18545 attempts to save information for global variables which cannot be
18547 (Get_Current_Value_Condition): Handle conditions the other way round
18548 (constant on left). Also handle right operand of AND and AND THEN
18549 (Set_Current_Value_Condition): Corresponding changes
18550 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
18551 (Get_Current_Value_Condition): Handle simple boolean operands
18552 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
18553 (Get_Current_Value_Condition): If the variable reference is within an
18554 if-statement, does not appear in the list of then_statments, and does
18555 not come from source, treat it as being at unknown location.
18556 (Get_Current_Value_Condition): Enhance to allow while statements to be
18557 processed as well as if statements.
18558 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
18560 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
18561 of loop. This is safe now that we fixed Kill_Current_Values.
18562 (OK_To_Do_Constant_Replacement): Check whether current scope is
18563 Standard, before examining outer scopes.
18565 2006-10-31 Vincent Celier <celier@adacore.com>
18567 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
18568 When True, apply VMS treatment to children of packages A, G, I and S.
18571 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
18573 2006-10-31 Robert Dewar <dewar@adacore.com>
18574 Ed Schonberg <schonberg@adacore.com>
18576 * freeze.adb: Add handling of Last_Assignment field
18577 (Warn_Overlay): Supply missing continuation marks in error msgs
18578 (Freeze_Entity): Add check for Preelaborable_Initialization
18580 * g-comlin.adb: Add Warnings (Off) to prevent new warning
18582 * g-expect.adb: Add Warnings (Off) to prevent new warning
18584 * lib-xref.adb: Add handling of Last_Assignment field
18585 (Generate_Reference): Centralize handling of pragma Obsolescent here
18586 (Generate_Reference): Accept an implicit reference generated for a
18587 default in an instance.
18588 (Generate_Reference): Accept a reference for a node that is not in the
18589 main unit, if it is the generic body corresponding to an subprogram
18592 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
18594 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
18596 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18598 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18599 use clauses, to avoid messages on packages used to qualify, and also
18600 to avoid messages from obsolescent units.
18601 (Warn_On_Useless_Assignments): Don't generate messages for imported
18602 and exported variables.
18603 (Warn_On_Useless_Assignments): New procedure
18604 (Output_Obsolescent_Entity_Warnings): New procedure
18605 (Check_Code_Statement): New procedure
18607 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
18608 Change name Is_Ada_2005 to Is_Ada_2005_Only
18609 (Last_Assignment): New field for useless assignment warning
18611 2006-10-31 Olivier Hainque <hainque@adacore.com>
18613 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18614 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18616 2006-10-31 Bob Duff <duff@adacore.com>
18617 Robert Dewar <dewar@adacore.com>
18618 Ed Schonberg <schonberg@adacore.com>
18620 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18621 Ada 95 mode, because it violates the new rules for AI-318.
18623 * g-awk.ads: Use overloaded subprograms in every case where we used to
18624 have a default of Current_Session. This makes the code closer to be
18625 correct for both Ada 95 and 2005.
18627 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18628 code, relying on the fact that the compiler generates a warning
18629 instead of an error in -gnatg mode.
18631 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18632 E_Return_Statement entity kind.
18633 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18635 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18636 report an error if the reserved word abstract has been previously found.
18637 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18639 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18640 parenthesized range attribute usage
18641 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18643 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18644 in the syntax for extended_return_statement. This is not in the latest
18645 RM, but the ARG is expected to issue an AI allowing this.
18646 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18647 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18648 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18649 P_Return_Statement): Parse the new syntax for extended_return_statement.
18651 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18652 Output_End_Missing): Add error-recovery code for the new
18653 extended_return_statement syntax; that is, the new E_Return entry on
18656 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18657 limited to nonlimited, because otherwise we violate the new Ada 2005
18658 rules about returning limited types in function Create_AST_Handler in
18661 * sem.adb (Analyze): Add cases for new node kinds
18662 N_Extended_Return_Statement and N_Return_Object_Declaration.
18664 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18665 type is in the same category as type of context before applying check,
18666 to prevent anomalies in instantiations.
18667 (Resolve_Aggregate): Remove test for limited components in aggregates.
18668 It's unnecessary in Ada 95, because if it has limited components, then
18669 it must be limited. It's wrong in Ada 2005, because limited aggregates
18671 (Resolve_Record_Aggregate): Move check for limited types later, because
18672 OK_For_Limited_Init requires its argument to have been resolved.
18673 (Get_Value): When copying the component default expression for a
18674 defaulted association in an aggregate, use the sloc of the aggregate
18675 and not that of the original expression, to prevent spurious
18676 elaboration errors, when the expression includes function calls.
18677 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18678 were missing. We also didn't handle qualified expressions. Now also
18679 allow function calls. Use new common routine OK_For_Limited_Init.
18680 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18681 with space can upper case letter).
18683 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18684 Has_Static_Discriminants flag
18685 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18686 type with discriminants.
18687 (Process_Range_Expr_In_Decl): Do validity checks on range
18688 (Build_Discriminant_Constraints): Use updated form of
18689 Denotes_Discriminant.
18690 (Process_Subtype): If the subtype is a private subtype whose full view
18691 is a concurrent subtype, introduce an itype reference to prevent scope
18693 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18694 Record_Type_Declaration): The functionality of the subprograms
18695 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18696 is now performed by a single routine.
18697 (Build_Derived_Record_Type): If the type definition includes an explicit
18698 indication of limitedness, then the type must be marked as limited here
18699 to ensure that any access discriminants will not be treated as having
18700 a local anonymous access type.
18701 (Check_Abstract_Overriding): Issue a detailed error message when an
18702 abstract subprogram was not overridden due to incorrect mode of its
18704 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18705 synchronized private extension declarations. Verify that the ancestor is
18706 a limited or synchronized interface or in the generic case, the ancestor
18707 is a tagged limited type or synchronized interface and all progenitors
18708 are either limited or synchronized interfaces.
18709 Derived_Type_Declaration): Check for presence of private extension when
18710 dealing with synchronized formal derived types.
18711 Process_Full_View): Enchance the check done on the usage of "limited" by
18712 testing whether the private view is synchronized.
18713 Verify that a synchronized private view is completed by a protected or
18715 (OK_For_Limited_Init_In_05): New function.
18716 (Analyze_Object_Declaration): Move check for limited types later,
18717 because OK_For_Limited_Init requires its argument to have been resolved.
18718 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18719 in order to alleviate the upward compatibility introduced by AI-318.
18720 (Constrain_Corresponding_Record): If the constraint is for a component
18721 subtype, mark the itype as frozen, to avoid out-of-scope references to
18722 discriminants in the back-end.
18723 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18724 this subprogram against wrong sources.
18725 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18726 discriminant of limited type completed with a protected type, when the
18727 discriminant is used to constrain a private component of the type, and
18728 expansion is disabled.
18729 (Find_Type_Of_Object): Do not treat a return subtype that is an
18730 anonymous subtype as a local_anonymous_type, because its accessibility
18731 level is the return type of the enclosing function.
18732 (Check_Initialization): In -gnatg mode, turn the error "cannot
18733 initialize entities of limited type" into a warning.
18734 (OK_For_Limited_Init): Return true for generated nodes, since it
18735 sometimes violates the legality rules.
18736 (Make_Incomplete_Declaration): If the type for which an incomplete
18737 declaration is created happens to be the currently visible entity,
18738 preserve the homonym chain when removing it from visibility.
18739 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18740 inherited subprograms.
18741 (Access_Definition): If this is an access to function that is the return
18742 type of an access_to_function definition, context is a type declaration
18743 and the scope of the anonymous type is the current one.
18744 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18745 incomplete subtype to the set of private dependents of the original
18747 (Constrain_Discriminated_Type): Emit an error message whenever an
18748 incomplete subtype is being constrained.
18749 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18750 corresponding subtype of the full view of the original incomplete type.
18751 (Check_Incomplete): Properly detect invalid usage of incomplete types
18754 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18756 * g-catiio.ads, g-catiio.adb (Value): New function.

18762 Integer_Address arithmetic, as in Set_Valid.
18764 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18765 Robert Dewar <dewar@adacore.com>
18767 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18768 handling executable extension manually and duplicating code.
18770 * make.adb: Implement new -S switch
18771 (Gnatmake): Use new function Osint.Executable_Name instead
18772 of handling executable extension manually.
18774 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18775 is specified, the executable name ends with this suffix.
18776 Take advantage of Osint.Executable_Name instead of duplicating code.
18778 * switch-m.adb: Recognize new gnatmake -S switch
18780 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18782 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18785 * makeusg.adb: Add line for gnatmake -S switch
18787 2006-10-31 Vincent Celier <celier@adacore.com>
18789 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18790 call it with -static-libgcc, as there are some platforms, such as
18791 Darwin, where one of these two switches is compulsory to link.
18793 2006-10-31 Vincent Celier <celier@adacore.com>
18795 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18796 instead of ADA_PROJECT_PATH, for the project path.
18797 (Gnatls): When displaying the project path directories, use host dir
18800 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18801 names in the project path, as absolute paths may correspond to
18802 multi-valued VMS logical names.
18804 2006-10-31 Vincent Celier <celier@adacore.com>
18806 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18807 absolute path name.
18808 (Locate_Regular_File): Ditto
18809 (Change_Dir): Remove, no longer used
18810 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18811 on Windows. Get it calling Get_Current_Dir.
18812 (OpenVMS): Remove imported boolean, no longer needed.
18813 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18814 (Pid_To_Integer): New function to convert a Process_Id to Integer
18816 2006-10-31 Thomas Quinot <quinot@adacore.com>
18818 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18819 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18821 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18824 2006-10-31 Robert Dewar <dewar@adacore.com>
18826 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
18827 initial letter o as a zero.
18829 2006-10-31 Robert Dewar <dewar@adacore.com>
18831 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
18833 2006-10-31 Robert Dewar <dewar@adacore.com>
18835 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18837 (Layout_Variant_Record): Retrieve the discriminants from the entity
18838 rather than from the type definition, because in the case of a full
18839 type for a private type we need to take the discriminants from the
18841 (Layout_Component_List): When applying the Max operator to variants with
18842 a nonstatic size, check whether either operand is static and scale that
18843 operand from bits to storage units before applying Max.
18844 (Layout_Type): In VMS, if a C-convention access type has no explicit
18845 size clause (and does not inherit one in the case of a derived type),
18846 then the size is reset to 32 from 64.
18848 2006-10-31 Vincent Celier <celier@adacore.com>
18850 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18851 its file has already been loaded, according to the unit being loaded,
18852 not to the current value of Multiple_Unit_Index.
18854 2006-10-31 Thomas Quinot <quinot@adacore.com>
18855 Eric Botcazou <ebotcazou@adacore.com>
18856 Arnaud Charlet <charlet@adacore.com>
18858 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
18859 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
18861 (a-except.o): Pass it to the compiler.
18862 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
18863 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
18864 a-calend-mingw.adb version.
18866 * Makefile.rtl: Added s-dsaser.
18867 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
18868 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
18869 Ada.Dispatching.Round_Robin.
18870 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
18872 * Make-lang.in: Remove all references to gt-ada-decl.h.
18873 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
18875 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
18876 Update dependencies.
18878 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
18880 2006-10-31 Vincent Celier <celier@adacore.com>
18882 * mlib-utl.adb (Initialized): Remove, no longer used
18883 (Initialize): Remove, no longer used
18884 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18885 if there is one, the archive indexer. Fail if the archive builder cannot
18887 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18890 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18892 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18893 Process_Body_Clauses): If the context of a body includes a use clause
18894 for P.Q then a with_clause for P in the same body is not redundant,
18895 even if the spec also has a with_clause on P.
18896 Add missing continuation mark to error msg
18897 (Build_Limited_Views): A limited view of a type is tagged if its
18898 declaration includes a record extension.
18899 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18900 node, even if the subunit has errors. This avoids malfunction by
18901 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18902 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18903 generation of obsolescent messages for with statements (cannot do
18904 this too early, or we cannot implement avoiding the messages in the
18905 case of obsolescent units withing obsolescent units).
18906 (Install_Siblings): If the with_clause is on a remote descendant of
18907 an ancestor of the current compilation unit, find whether there is
18908 a sibling child unit that is immediately visible.
18909 (Remove_Private_With_Clauses): New procedure, invoked after completing
18910 the analysis of the private part of a nested package, to remove from
18911 visibility the private with_clauses of the enclosing package
18913 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18914 now centralized in Generate_Reference.
18915 (Install_Limited_Context_Clauses): Remove superfluous error
18916 message associated with unlimited view visible through use
18917 and renamings. In addition, at the point in which the error
18918 is reported, we add the backslash to the text of the error
18919 to ensure that it is reported as a single error message.
18920 Use new // insertion for some continuation messages
18921 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18922 to create implicit with_clause for parent unit mentioned in original
18923 limited_with_clause.
18924 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18925 unit is a child unit. For ASIS queries.

18942 a formal object declaration with an access definition or a subtype mark
18943 with a null exclusion.
18944 (P_Generic_Association): Handle association with box, and others_choice
18945 with box, to support Ada 2005 partially parametrized formal packages.
18947 2006-10-31 Robert Dewar <dewar@adacore.com>
18948 Javier Miranda <miranda@adacore.com>
18950 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18951 (P_Type_Declaration): Remove barrier against the reserved word "limited"

18954 private extensions.
18955 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18956 to P_Interface_Type_Definition.

18988 of sources, even if it is not the first time, as it is for another
18990 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18991 dot, instead of replacing only the first '_'.
18993 * prj-part.adb (Parse): Convert project file path to canonical form
18995 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18996 extended, the project id of the project extending it is recorded in its

19005 Robert Dewar <dewar@adacore.com>
19007 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
19008 only a restriction warning is active for the given restriction. This is
19009 desirable because we do not want to modify code in the case where only
19011 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
19012 causes overriding of real restrictions.
19013 Take advantage of new No_Restrictions constant.
19015 * raise.h: (__gnat_set_globals): Change profile.
19017 2006-10-31 Arnaud Charlet <charlet@adacore.com>
19019 * rtsfind.adb: Remove s-polint from comment as it exists no more.
19022 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
19023 Move all the entities in obsolete package System.PolyORB_Interface to
19024 System.Partition_Interface.

19042 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
19043 properly an attempt to apply Unchecked_Access to a protected operation.
19044 (OK_Self_Reference): New subprogram to check the legality of an access
19045 attribute whose prefix is the type of an enclosing aggregate.
19046 Generalizes previous mechanism to handle attribute references nested
19047 arbitrarily deep within the aggregate.
19048 (Analyze_Access_Attribute): An access attribute whose prefix is a type
19049 can appear in an aggregate if this is a default-initialized aggregate
19050 for a self-referential type.
19051 (Resolve_Attribute, case Access): Ditto.
19052 Add support for new implementation defined attribute Stub_Type.

19054 (Analyze_Attribute, case Attribute_Stub_Type): New case.
19055 (Stream_Attribute_Available): Implement using new subprogram from
19056 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
19057 Has_Specified_Stream_Attribute flag.
19058 Disallow Storage_Size and Storage_Pool for access to subprogram
19059 (Resolve_Attribute, case 'Access et al): Take into account anonymous
19060 access types of return subtypes in extended return statements. Remove
19061 accessibility checks on anonymous access types when Unchecked_Access is
19063 (Analyze_Attribute): Add support for the use of 'Class to convert
19064 a class-wide interface to a tagged type.
19065 Add support for the attribute Priority.
19066 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
19067 whether the designated type is discriminated with a constrained partial
19068 view and require static matching in that case.
19069 Add local variable Des_Btyp. The Designated_Type
19070 of an access to incomplete subtype is either its non-limited view if
19071 coming from a limited with or its etype if regular incomplete subtype.
19073 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
19074 Fix predicate to identify and allow cases of (expander-generated)
19075 references to tag of designated object of a RACW.
19076 (Validate_Static_Object_Name): In Ada 2005, a formal object is
19077 non-static, and therefore cannot appear as a primary in a preelaborable
19079 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
19080 Has_Read_Write_Attributes.
19081 (Has_Read_Write_Attributes): Reimplement in termes of
19082 Has_Stream_Attribute_Definition.
19083 (Missing_Read_Write_Attributes): When checking component types in a
19084 record, unconditionally call Missing_Read_Write_Attributes recursively
19085 (remove guard checking for Is_Record_Type / Is_Access_Type).
19087 2006-10-31 Robert Dewar <dewar@adacore.com>
19089 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
19090 useless assignments here and conditionalize it on absence of exception

19093 detection code, for new handling of formal packages.
19095 2006-10-31 Ed Schonberg <schonberg@adacore.com>
19096 Hristian Kirtchev <kirtchev@adacore.com>
19098 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
19099 that has been constant-folded, preserve information of original tree,
19101 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
19102 generated private extension declaration if the formal derived type is
19103 synchronized. Carry synchronized present over to the generated private
19105 (Validate_Derived_Type_Instance): Ensure that the actual of a
19106 synchronized formal derived type is a synchronized tagged type.
19107 (Instantiate_Formal_Package): When creating the instantiation used to
19108 validate the actual package of a formal declared without a box, check
19109 whether the formal itself depends on a prior actual.
19110 (Instantiate_Formal_Subprogram): Create new entities for the defining
19111 identifiers of the formals in the renaming declaration, for ASIS use.
19112 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
19113 a renaming declaration or a subtype declaration for an actual in an
19114 instance, capture location information of declaration in generic, for
19116 (Instantiate_Formal_Package): Add comments on needed additional tests.
19117 AI-317 (partial parametrization) is fully implemented.
19118 (Validate_Private_Type_Instance): Add check for actual which
19119 must have preelaborable initialization
19120 Use new // insertion for some continuation messages
19121 (Analyze_Formal_Object_Declaration): Change usage of Expression to
19122 Default_Expression. Add type retrieval when the declaration has an
19123 access definition. Update premature usage of incomplete type check.
19124 (Check_Access_Definition): New subsidiary routine. Check whether the
19125 current compilation version is Ada 05 and the supplied node has an
19127 (Instantiate object): Alphabetize local variables. Handle the creation
19128 of new renaming declarations with respect to the kind of definition
19129 used - either an access definition or a subtype mark. Guard against
19130 unnecessary error message in the context of anonymous access types after
19131 they have been resolved. Add check for required null exclusion in a
19132 formal object declaration.
19133 (Switch_View): A private subtype of a non-private type needs to be
19134 switched (the base type can have been switched without its private
19135 dependents because of the last branch of Check_Private_View.
19136 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
19138 (Instantiate_Type): Emit an error message whenever a class-wide type of
19139 a tagged incomplete type is used as a generic actual.
19140 (Find_Actual_Type): Extend routine to handle a component type in a child
19141 unit that is imported from a formal package in a parent.
19142 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
19143 agree on constrainedness, rather than checking against ultimate ancestor
19144 (Instantiate_Subprogram_Body): Create a cross-reference link to the
19145 generic body, for navigation purposes.
19147 2006-10-31 Robert Dewar <dewar@adacore.com>
19148 Thomas Quinot <quinot@adacore.com>
19150 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
19152 (New_Stream_Subprogram): When processing an attribute definition clause
19153 for a stream-oriented subprogram, record an entity node occurring at
19154 the point of clause to use for checking the visibility of the clause,
19155 as defined by 8.3(23) as amended by AI-195.
19156 (New_Stream_Subprogram): New procedure, factoring behaviour from both
19157 New_Stream_Function and New_Stream_Procedure.
19158 (New_Stream_Function, New_Stream_Procedure): Removed.
19159 (Analyze_Attribute_Definition_Clause, case Address): Check new
19160 Alignment_Check check

19163 Javier Miranda <miranda@adacore.com>
19164 Robert Dewar <dewar@adacore.com>
19166 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
19167 generate the same errors compiling under -gnatc.
19168 (Try_Object_Operation): If no candidate interpretation succeeds, but
19169 there is at least one primitive operation with the right name, report
19170 error in call rather than on a malformed selected component.
19171 (Analyze_Selected_Component): If the prefix is an incomplete type from
19172 a limited view, and the full view is available, use the full view to
19173 determine whether this is a prefixed call to a primitive operation.
19174 (Operator_Check): Verify that a candidate interpretation is a binary
19175 operation before checking the type of its second formal.
19176 (Analyze_Call): Add additional warnings for function call contexts not
19178 (Analyze_Allocator): Move the check for "initialization not allowed for
19179 limited types" after analyzing the expression. This is necessary,
19180 because OK_For_Limited_Init looks at the structure of the expression.
19181 Before analysis, we don't necessarily know what sort of expression it
19182 is. For example, we don't know whether F(X) is a function call or an
19183 indexed component; the former is legal in Ada 2005; the latter is not.
19184 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
19185 were missing. We also didn't handle qualified expressions. Now also
19186 allow function calls. Use new common routine OK_For_Limited_Init.
19187 (Analyze_Type_Conversion): Do not perform some legality checks in an
19188 instance, because the error message will be redundant or spurious.
19189 (Analyze_Overloaded_Selected_Component): Do not do style check when
19190 setting an entity, since we do not know it is the right entity yet.
19191 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
19192 (Analyze_Overloaded_Selected_Component): Same change
19193 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
19194 since regular incomplete subtypes are transformed into corresponding
19195 subtypes of their full views.
19196 (Complete_Object_Operation): Treat name of transformed subprogram call
19197 as coming from source, for browsing purposes.
19198 (Try_Primitive_Operation): If formal is an access parameter, compare
19199 with base type of object to determine whether it is a primitive
19201 (Operator_Check): If no interpretation of the operator matches, check
19202 whether a use clause on any candidate might make the operation legal.
19203 (Try_Class_Wide_Operation): Check whether the first parameter is an
19204 access type whose designated type is class-wide.

19211 warn on infinite loops.
19212 Add \\ to some continuation messages
19213 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
19214 (Process_Bounds): If the bounds are integer literals that result from
19215 constant-folding, and they carry a user-defined type, preserve that type
19216 rather than treating this as an integer range.
19217 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
19218 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
19219 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
19220 left hand side of assignment.
19221 (Analyze_Assignment): Add suport to manage assigments to the attribute
19222 priority of a protected object.
19223 (Check_Possible_Current_Value_Condition): Allow fully qualified names
19224 not just identifiers.
19225 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
19226 or AND THEN for possible tracking.
19227 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
19228 case of while loops so we can track values in the loop body.
19230 2006-10-31 Ed Schonberg <schonberg@adacore.com>
19231 Hristian Kirtchev <kirtchev@adacore.com>
19232 Bob Duff <duff@adacore.com>
19234 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
19235 procedure cannot be a protected operation (it is a basic_declaration,
19236 not a subprogram_declaration).
19237 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
19238 Subp. Add logic for entry processing.
19239 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
19240 Determine whether an entry or subprogram of a protected or task type
19241 override an inherited primitive of an implemented interface.
19242 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
19243 Update the actual used in calls to Check_Overriding_Indicator.
19244 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
19245 generate the proper reference to the parent unit, for cross-reference.
19246 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
19248 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
19249 (Add_Extra_Formal): Revise procedure to allow passing in associated
19250 entity, scope, and name suffix, and handle setting of the new
19251 Extra_Formals field.
19252 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
19253 pass new parameters. Add support for adding the new extra access formal
19254 for functions whose calls are treated as build-in-place.
19255 (Analyze_A_Return_Statement): Correct casing in error message.
19256 Move Pop_Scope to after Analyze_Function_Return, because an extended
19257 return statement really is a full-fledged scope. Otherwise, visibility
19258 doesn't work right. Correct use of "\" for continuation messages.
19259 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
19260 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
19261 the node doesn't get properly marked as analyzed.
19262 (Analyze_Subprogram_Body): If subprogram is a function that returns
19263 an anonymous access type that denotes a task, build a Master Entity
19265 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
19266 proper usage of null exclusion in a result definition.
19267 (Process_Formals): Code cleanup and new error message.
19268 (Process_Formals): Detect incorrect application of null exclusion to
19270 (Conforming_Types): Handle conformance between [sub]types and itypes
19271 generated for entities that have null exclusions applied to them.
19272 (Maybe_Primitive_Operation): Add an additional type retrieval when the
19273 base type is an access subtype. This case arrises with null exclusions.
19274 (New_Overloaded_Entity): Do not remove the overriden entity from the
19275 homonym chain if it corresponds with an abstract interface primitive.
19276 (Process_Formals): Replace membership test agains Incomplete_Kind with a
19277 call to the synthesized predicate Is_Incomplete_Type.
19278 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
19280 (Analyze_Subprogram_Declaration): Check that abstract interface
19281 primitives are abstract or null.
19282 (Analyze_Subprogram_Specification): Remove previous check for abstract
19283 interfaces because it was not complete.
19284 (Has_Interface_Formals): Removed.
19286 2006-10-31 Ed Schonberg <schonberg@adacore.com>
19287 Javier Miranda <miranda@adacore.com>
19289 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
19290 of Analyze_Package_Body, to create Itype references for anonymous
19291 access types created in the package declaration, whose designated types
19292 may have only a limited view.
19293 (Analyze_Package_Specification): For the private part of a nested
19294 package, install private_with_clauses of enclosing compilation unit if
19295 we are in its visible part.
19296 (Declare_Inherited_Private_Subprograms): Complete barrier
19297 to ensure that the primitive operation has an alias to some parent
19298 primitive. This is now required because, after the changes done for the
19299 implementation of abstract interfaces, the contents of the list of
19300 primitives has entities whose alias attribute references entities of
19301 such list of primitives.
19302 (Analyze_Package_Specification): Simplify code that handles parent units
19303 of instances and formal packages.
19304 (Uninstall_Declarations): Check the convention consistency among
19305 primitive overriding operations of a tagged record type.

19314 expected and found set right)
19315 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
19316 (Analyze_Generic_Renaming): Same fix
19317 (Use_One_Package): Do not take into account the internal entities of
19318 abstract interfaces during the analysis of entities that are marked
19319 as potentially use-visible.
19320 (Find_Type): Handle the case of an attribute reference for
19321 implementation defined attribute Stub_Type (simply let the analysis of
19322 the attribute reference rewrite it).
19323 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
19324 type that appears in a Use_Type clause.
19325 (Analyze_Object_Renaming): Add support for renaming of the Priority
19327 (Find_Type): In Ada 2005, a task type can be used within its own body,
19328 when it appears in an access definition.
19329 (Analyze_Object_Renaming): Remove warning on null_exclusion.
19330 (Analyze_Object_Renaming): Introduce checks for required null exclusion
19331 in a formal object declaration or in a subtype declaration.
19332 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
19333 (Check_Null_Exclusion): New local routine to
19334 Analyze_Subprogram_Renaming. Check whether the formals and return
19335 profile of a renamed subprogram have required null exclusions when
19336 their counterparts of the renaming already impose them.
19337 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
19338 Determine whether an entity is inside a generic scope.
19339 (In_Open_Scope): First pass of documentation update.
19340 (Find_Expanded_Name): Add support for shadow entities associated with
19341 limited withed packages. This is required to handle nested packages.
19342 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
19343 that makes a renaming of a limited withed package illegal.

19350 (Analyze_Task_Definition): Ditto.
19351 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
19352 (Check_Overriding_Indicator): To find overridden interface operation,
19353 examine only homonyms that have an explicit subprogram declaration, not
19354 inherited operations created by an unrelated type derivation.
19355 (Check_Overriding_Indicator): When checking for the presence of "null"
19356 in a procedure, ensure that the queried node is a procedure
19358 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
19359 type when the formal is an access to variable.
19360 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
19361 (Analyze_Task_Type): Same addition

20204 evaluate the conversion at run-time.

20824 (Gnat1drv): Use a goto to end of main subprogram instead of
20825 Exit_Program (E_Success) so that finalization can occur normally.
20827 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>

20843 Thomas Quinot <quinot@adacore.com>
20845 * checks.adb (Build_Discriminant_Checks): If the expression being
20846 checks is an aggregate retrieve the values of its discriminants to
20847 generate the check, rather than creating a temporary and a reference
20849 (Apply_Access_Check): Rewritten to handle new Is_Known_Null flag
20850 (Install_Null_Excluding_Check): Ditto
20851 (Selected_Length_Checks): Build actual subtype for the original Ck_Node,

20864 error message with the full switch.
20865 Eliminate numeric switches for binder/gnatmake
20867 * switch.ads, switch.adb (Bad_Switch): New procedure
20869 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
20870 Remove 0-9 as debug flag character possibilities
20871 -d is now controlling the primary stack size when its value is a
20872 positive. Also add checks against invalid values, and support for kb,
20873 mb. Ditto for -D switch.
20875 2006-02-13 Robert Dewar <dewar@adacore.com>
20876 Serguei Rybin <rybin@adacore.com>
20878 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
20879 save/restore routines.
20880 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20881 were not always properly handled previously.
20882 Since we are changing the tree format anyway, also get rid of the
20883 junk obsolete Immediate_Errors flag.
20884 (Tree_Read): Change the way of reading Tree_Version_String - now we
20885 read the version string from the tree even if its length is not the
20886 same as the length of the version string computed from Gnatvsn.
20887 (Search_Directory_Present): New Boolean flag for the compiler.
20888 Define Tree_Version_String as a dynamic string.
20889 (Default_Stack_Size): new variable, used to handle switch -d.
20892 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
20893 only for main unit.
20894 Add pragma Ada_2005 (synonym for Ada_05)
20895 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20896 were not always properly handled previously.
20898 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
20899 explicit Ada_95 to Ada_2005.

20902 Robert Dewar <dewar@adacore.com>
20903 Ed Schonberg <schonberg@adacore.com>
20905 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
20906 against errors in the source program: a private types for which the
20907 corresponding full type declaration is missing and pragma CPP_Virtual
20909 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
20910 (Is_Known_Null): New flag
20911 (Has_Pragma_Pure): New flag
20912 (No_Return): Present in all entities, set only for procedures
20913 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20914 explicitly declared limited.
20915 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20916 entities. Only used for component marked Is_Tag. If present it stores
20917 the Offset_To_Top function used to provide this value in tagged types
20918 whose ancestor has discriminants.
20920 * exp_ch2.adb: Update status of new Is_Known_Null flag
20922 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
20924 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
20925 the categorization sense if Is_Pure was set by pragma Pure_Function.
20927 2006-02-13 Quentin Ochem <ochem@adacore.com>
20928 Olivier Hainque <hainque@adacore.com>
20930 * bindusg.adb: Updated documentation for -d and -D switches.
20932 * raise.h (__gnat_set_globals): added new parameter for
20933 Default_Stack_Size.
20935 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
20936 (__gnat_handle_vms_condition): Adjust context before raise.
20937 (__gnat_install_handler): Restore the global vector setup for GCC
20938 versions before 3.4, as the frame based circtuitry is not available
20940 (__gnat_set_globals): added a parameter default_stack_size
20941 (__gl_default_stack_size): new variable.
20943 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20945 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20946 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20947 does not exist in the Ada RM.
20948 (Compatible_Int_Bounds): Determine whether two integer range bounds
20949 are of equal length and have the same start and end values.
20950 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20951 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20952 aggregate when it is part of an object declaration.
20953 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20954 constrains discriminants of its parent, add explicitly the discriminant
20955 constraints of the ancestor by retrieving them from the
20956 stored_constraint of the parent.
20958 2006-02-13 Robert Dewar <dewar@adacore.com>
20960 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20961 attribute Mechanism_Code is applied to renamed subprogram, modify
20962 prefix to point to base subprogram.
20963 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20965 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20966 renamed subprograms so that the front-end must replace the prefix
20969 2006-02-13 Javier Miranda <miranda@adacore.com>
20970 Gary Dismukes <dismukes@adacore.com>
20972 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20973 availability of RE_Interface_Tag.
20974 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20975 (Freeze_Record_Type): Do not generate the tables associated with
20976 timed and conditional dispatching calls through synchronized
20977 interfaces if compiling under No_Dispatching_Calls restriction.
20978 When compiling for Ada 2005, for a nonabstract
20979 type with a null extension, call Make_Controlling_Function_Wrappers
20980 and insert the wrapper function declarations and bodies (the latter
20981 being appended as freeze actions).
20982 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20983 predefined primitives associated with timed and conditional
20984 dispatching calls through synchronized interfaces if we are
20985 compiling under No_Dispatching_Calls.
20986 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20987 service is available before generating a call.
20988 (Make_Controlling_Function_Wrappers): New procedure.
20989 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20990 access-to-limited-interfaces because they can be used to reference
20991 tasks that implement such limited interface.
20992 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20993 procedure spec and body of the Offset_To_Top function that is generated
20994 when the parent of a type with discriminants has secondary dispatch
20996 (Init_Secondary_Tags): Handle the case in which the parent of the type
20997 containing secondary dispatch tables has discriminants to generate the
20998 correct arguments to call Set_Offset_To_Top.
20999 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
21001 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
21002 Add Wide_[Wide_]Expanded_Name.
21003 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
21004 the same functionality of Get_Prim_Op_Address but applied to predefined
21005 primitive operations because the pointers to the predefined primitives
21006 are now saved in a separate table.
21007 (Parent_Size): Modified to get access to the separate table of primitive
21008 operations or the parent type.
21009 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
21010 functionality of Set_Prim_Op_Address but applied to predefined primitive
21012 (Set_Signature): New subprogram used to store the signature of a DT.
21013 (Displace): If the Offset_To_Top value is not static then call the
21014 function generated by the expander to get such value; otherwise use
21015 the value stored in the table of interfaces.
21016 (Offset_To_Top): The type of the actual has been changed to Address to
21017 give the correct support to tagged types with discriminants. In this
21018 case this value is stored just immediately after the tag field.
21019 (Set_Offset_To_Top): Two new formals have been added to indicate if the
21020 offset_to_top value is static and hence pass this value to the run-time
21021 to store it in the table of interfaces, or else if this value is dynamic
21022 and then pass to the run-time the address of a function that is
21023 generated by the expander to provide this value for each object of the
21026 * rtsfind.ads (Default_Prin_Op_Count): Removed.
21027 (Default_Prim_Op_Count): New entity
21028 (Get_Predefined_Prim_Op_Address): New entity
21029 (Set_Predefined_Prim_Op_Address): New entity

21033 Ed Schonberg <schonberg@adacore.com>
21035 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
21036 Make_Adjust_Call done for a newly-allocated object.
21038 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
21039 in a subprogram are wrapped in a cleanup block, indicate that the
21040 subprogram contains an inner block with an exception handler.
21041 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
21042 Adjust call is for a newly-allocated object. In that case we must not
21043 assume that the finalization list chain pointers are correct (since they
21044 come from a bit-for-bit copy of the original object's pointers) so if
21045 the attach level would otherwise be zero (no change), we set it to 4
21046 instead to cause the pointers to be reset to null.
21048 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
21049 reset chain pointers to null.
21051 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21053 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
21054 string, and the context requires a loop for the assignment (e.g.
21055 because the left-hand side is packed), generate a unique name for the
21056 temporary that holds the string, to prevent spurious name clashes.
21058 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21059 Javier Miranda <miranda@adacore.com>
21060 Robert Dewar <dewar@adacore.com>
21061 Gary Dismukes <dismukes@adacore.com>
21063 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
21064 return unconstrained arrays.
21066 (Expand_Call): An indirect call through an access parameter of a
21067 protected operation is not a protected call.
21068 Add circuit to raise CE in Ada 2005 mode following call
21069 to Raise_Exception.
21070 (Register_DT_Entry): Do nothing if
21071 the run-time does not give support to abstract interfaces.
21072 (Freeze_Subprogram): In case of dispatching operations, do not generate
21073 code to register the operation in the dispatch table if the source
21074 is compiled with No_Dispatching_Calls.
21075 (Register_Predefined_DT_Entry): Generate code that calls the new
21076 run-time subprogram Set_Predefined_Prim_Op_Address instead of
21077 Set_Prim_Op_Address.
21079 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
21080 on array assignments if the right-hand side is a function call that has
21081 been inlined. Check is performed on the assignment in the block.
21082 (Process_Bounds): If bounds and range are overloaded, apply preference
21083 rule for root operations to disambiguate, and diagnose true ambiguity.
21084 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
21085 a tag-indeterminate right-hand side even when Expander_Active is True.
21086 Needed to ensure that dispatching calls to T'Input are allowed and
21087 get the tag of the target class-wide object.
21089 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
21090 an inherited primitive operation that already overrides several
21091 abstract interface primitives. For transitivity, the new entity must
21092 also override all the abstract interface primitives covered by the
21093 inherited overriden primitive.
21094 Emit warning if new entity differs from homograph in same scope only in
21095 that one has an access parameter and the other one has a parameter of
21096 a general access type with the same designated type, at the same
21097 position in the signature.
21098 (Make_Inequality_Operator): Use source locations of parameters and
21099 subtype marks from corresponding equality operator when creating the
21100 tree structure for the implicit declaration of "/=". This does not
21101 change anything in behaviour except that the decoration of the
21102 components of the subtree created for "/=" allows ASIS to get the
21103 string images of the corresponding identifiers.
21104 (Analyze_Return_Statement): Remove '!' in warning message.
21105 (Check_Statement_Sequence): Likewise.
21106 (Analyze_Subprogram_Body): For an access parameter whose designated type
21107 is an incomplete type imported through a limited_with clause, use the
21108 type of the corresponding formal in the body.
21109 (Check_Returns): Implicit return in No_Return procedure now raises
21110 Program_Error with a compile time warning, instead of beging illegal.
21111 (Has_Single_Return): Function returning unconstrained type cannot be
21112 inlined if expression in unique return statement is not an identifier.
21113 (Build_Body_To_Inline): It is possible to inline a function call that
21114 returns an unconstrained type if all return statements in the function
21115 return the same local variable. Subsidiary procedure Has_Single_Return
21116 verifies that the body conforms to this restriction.
21118 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
21119 same type, and one of them is of an anonymous access type, convert
21120 the other operand to it, so that this is a valid binary operation for
21122 (Resolve_Type_Conversion): Handle subtypes of protected types and
21123 task types when accessing to the corresponding record type.
21124 (Resolve_Allocator): Add '\' in 2-line warning message.
21125 Remove '!' in warning message.
21126 (Resolve_Call): Add '\' in 2-line warning message.
21127 (Valid_Conversion): Likewise.
21128 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
21129 resulting type may be an access type with an implicit dereference.
21130 Obtain the proper component from the designated type.
21131 (Make_Call_Into_Operator): Handle properly a call to predefined equality
21132 given by an expanded name with prefix Standard, when the operands are
21133 of an anonymous access type.
21134 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
21135 Explicit_Dereference and Resolve_Selected_Component, to verify that the
21136 prefix of the expression is not of an incomplete type. Allows full
21137 diagnoses of all semantic errors.
21138 (Resolve_Actuals): If the actual is an allocator whose directly
21139 designated type is a class-wide interface we build an anonymous
21140 access type to use it as the type of the allocator. Later, when
21141 the subprogram call is expanded, if the interface has a secondary
21142 dispatch table the expander will add a type conversion to force
21143 the displacement of the pointer.
21144 (Resolve_Call): If a function that returns an unconstrained type is
21145 marked Inlined_Always and inlined, the call will be inlined and does
21146 not require the creation of a transient scope.
21147 (Check_Direct_Boolean_Op): Removed
21148 (Resolve_Comparison_Op): Remove call to above
21149 (Resolve_Equality_Op): Remove call to above
21150 (Resolve_Logical_Op): Inline above, since this is only call.
21151 (Valid_Conversion): Handle properly conversions between arrays of
21152 convertible anonymous access types.
21155 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
21156 the literal in an unchecked conversion, because GCC 4.x needs a static
21157 value for a string bound.
21159 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21160 Hristian Kirtchev <kirtchev@adacore.com>
21162 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
21163 components of the corresponding record, take into account component
21164 definitions that are access definitions.
21165 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
21166 procedure is not considered a dispatching call and will be expanded
21169 2006-02-13 Javier Miranda <miranda@adacore.com>
21171 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
21172 controlling argument of the dispatching call is an abstract interface
21173 class-wide type then we use it directly.
21174 Check No_Dispatching_Calls restriction.
21175 (Default_Prim_Op_Position): Remove the code that looks for the last
21176 entity in the list of aliased subprograms. This code was wrong in
21178 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
21179 when the source is compiled with the No_Dispatching_Calls restriction.
21180 (Init_Predefined_Interface_Primitives): No need to inherit primitives
21181 if we are compiling with restriction No_Dispatching_Calls.
21182 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
21183 subprograms if we are compiling under No_Dispatching_Calls restriction.
21184 (Make_DT): Generate a dispatch table with a single dummy entry if
21185 we are compiling with the No_Dispatching_Calls restriction. In
21186 addition, in this case we don't generate code that calls to the
21187 following run-time subprograms: Set_Type_Kind, Inherit_DT.
21188 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
21189 of this subprogram if compiling with the No_Dispatching_Calls
21191 (Expand_Type_Conversion): Instead of using the actual parameter,
21192 the argument passed as parameter to the conversion function was
21193 erroneously referenced by the expander.
21194 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
21195 Set_Predefined_Primitive_Op_Address and Set_Signature.
21196 (Expand_Dispatching_Call): Generate call to
21197 Get_Predefined_Prim_Op_Address for predefined primitives.
21198 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
21199 predefined primitives.
21200 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
21201 primitives we reserve one dummy entry to ensure that the tag does not
21202 point to some memory that is associated with some other object. In
21203 addition, remove all the old code that generated the assignments
21204 associated with the signature of the dispatch table and replace them
21205 by a call to the new subprogram Set_Signature.
21206 (Set_All_DT_Position): Change the algorithm because now we have a
21207 separate dispatch table associated with predefined primitive operations.
21208 (Expand_Interface_Conversion): In case of non-static offset_to_top
21209 add explicit dereference to get access to the object after the call
21210 to displace the pointer to the object.
21211 (Expand_Interface_Thunk): Modify the generation of the actual used
21212 in the calls to the run-time function Offset_To_Top to fulfil its
21214 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
21216 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21218 * exp_dist.adb (Copy_Specification): For access parameters, copy
21219 Null_Exclusion flag, which will have been set for stream subprograms
21222 2006-02-13 Pascal Obry <obry@adacore.com>
21224 * expect.c (__gnat_expect_portable_execvp): New implementation. The
21225 previous implementation was using the C runtime spawnve routine but
21226 the corresponding wait was using directly the Win32 API. This was
21227 causing some times a lock when waiting for an event using
21228 WaitForSingleObject in __gnat_waitpid. This new implementation uses
21229 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
21230 API fixes this problem.
21232 2006-02-13 Robert Dewar <dewar@adacore.com>
21234 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
21237 2006-02-13 Thomas Quinot <quinot@adacore.com>
21239 * exp_pakd.ads: Fix typos in comments.
21241 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
21242 array reference that is an explicit dereference, mark the converted
21243 (packed) array reference as analyzed to prevent a forthcoming
21244 reanalysis from resetting its type to the original (non-packed) array

21248 Javier Miranda <miranda@adacore.com>
21249 Eric Botcazou <ebotcazou@adacore.com>
21251 * exp_util.ads, exp_util.adb (Find_Prim_Op,
21252 Is_Predefined_Primitive_Operation): When
21253 searching for the predefined equality operator, verify that operands
21254 have the same type.
21255 (Is_Predefined_Dispatching_Operation): Remove the code that looks
21256 for the last entity in the list of aliased subprograms. This code
21257 was wrong in case of renamings.
21258 (Set_Renamed_Subprogram): New procedure
21259 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
21260 Exp_Type constant computed when entering this subprogram.
21261 (Known_Null): New function
21262 (OK_To_Do_Constant_Replacement): New function
21263 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
21264 (Side_Effect_Free): An attribute reference 'Input is not free of
21265 side effect, unlike other attributes that are functions. (from code
21267 (Remove_Side_Effects): Expressions that involve packed arrays or records
21268 are copied at the point of reference, and therefore must be marked as
21269 renamings of objects.
21270 (Is_Predefined_Dispatching_Operation): Return false if the operation is
21271 not a dispatching operation.
21274 (Remove_Side_Effects): Lift enclosing type conversion nodes for
21275 elementary types in all cases.

21280 task types when accessing to the corresponding record type.
21281 Remove '!' in warning message.
21283 2006-02-13 Olivier Hainque <hainque@adacore.com>
21285 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
21286 to avoid useless and space inefficient overalignments on targets where
21287 Max_Alignment is larger than 16.
21289 2006-02-13 Pascal Obry <obry@adacore.com>
21291 * g-catiio.adb (Sec_Number): New type used to compute the number of
21292 seconds since 1-1-1970.
21293 (Image) [Natural]: The parameter was an Integer, as we can't deal with
21294 negative numbers (years, months...) it is better to have a Natural here.
21296 (Image) [Number]: Change parameter from Long_Integer to Number.
21297 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
21298 overflow for dates past year 2038.
21300 2006-02-13 Matthew Heaney <heaney@adacore.com>
21302 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise

21307 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
21309 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that

21314 * gnatcmd.adb (Rules_Switches): New table
21315 (Add_To_Rules_Switches): New procedure
21316 (GNATCmd): For command CHECK, put all options following "-rules" in the
21317 Rules_Switches table. Append these -rules switches after the -cargs
21320 2006-02-13 Robert Dewar <dewar@adacore.com>
21322 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
21323 These two cases were generating incorrect output, and if this unit
21324 was built with checks on, generated a discriminant mismatch constraint
21327 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21328 Robert Dewar <dewar@adacore.com>
21330 * lib-xref.adb (Get_Type_Reference): For a private type whose full
21331 view is an array type, indicate the component type as well, for
21332 navigation purposes.
21333 (Generate_Reference): Don't consider array ref on LHS to be a case
21334 of violating pragma Unreferenced.
21335 Do not give Ada 2005 warning except on real reference.
21337 2006-02-13 Vincent Celier <celier@adacore.com>
21339 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
21340 main source, add switch -mdebug-main=_ada_ so that the executable can
21341 be debugged by the standard VMS debugger.
21342 (Gnatmake): Set No_Main_Subprogram to True when there is no main
21343 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
21344 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
21345 of the last source, as the binding and linking phases are never
21347 Set all executable obsolete when rebuilding a library.
21349 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
21352 2006-02-13 Javier Miranda <miranda@adacore.com>
21355 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
21356 code to improve the error message reported when the program has
21357 declarations of abstract interface types and it is not compiled with
21358 the -gnat05 switch.
21359 (P_Access_Definition): Reorganize the code to improve the error
21360 message reported when the new Ada 2005 syntax for anonymous
21361 access types is used and the program is not compiled with the

21384 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
21385 unknown, use the location of the project to report the error.
21386 (When_No_Sources): New global variable
21387 (Report_No_Ada_Sources): New procedure
21388 (Check): New parameter When_No_Sources. Set value of global variable
21390 (Find_Sources): Call Report_No_Ada_Sources when appropriate
21391 (Get_Sources_From_File): Ditto
21392 (Warn_If_Not_Sources): Better warning messages indicating the unit name
21395 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
21396 Call Prj.Proc.Process with parameter When_No_Sources.
21398 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
21399 Call Recursive_Check with parameter When_No_Sources.
21400 (Recursive_Check): New parameter When_No_Sources. Call itself and
21401 Prj.Nmsc.Check with parameter When_No_Sources.
21402 (Process): New parameter When_No_Sources. Call Check with parameter
21404 (Copy_Package_Declarations): New procedure to copy renamed parameters
21405 and setting the location of the declared attributes to the location
21406 of the renamed package.

21412 * prj-makr.adb (Make): Preserve the comments from the original project
21414 When removing nodes (attributes Source_Dirs, Source_Files,
21415 Source_List_File and package Naming), save the comments and attach the
21416 saved comments to the newly created nodes.
21417 Do not add a with clause for the naming package if one already exists.
21419 2006-02-13 Javier Miranda <miranda@adacore.com>

21425 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
21426 aliased entities to look for the overriden abstract interface
21428 (Is_Interface_Subprogram): Complete documentation.
21429 (Check_Dispatching_Operation): Do not generate code to register the
21430 operation in the dispatch table if the source is compiled with
21431 restriction No_Dispatching_Calls.
21432 (Override_Dispatching_Operation): Check for illegal attempt to override
21433 No_Return procedure with procedure that is not No_Return
21434 (Check_Dispatching_Call): Suppress the check for an abstract operation
21435 when the original node of an actual is a tag-indeterminate attribute
21436 call, since the attribute, which must be 'Input, can never be abstract.
21437 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
21438 call to the Input attribute (even when rewritten).
21439 (Propagate_Tag): Augment comment to indicate the possibility of a call
21440 to an Input attribute.
21442 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
21443 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
21445 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
21446 No_Wide_Characters is no longer partition-wide
21447 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
21450 2006-02-13 Douglas Rupp <rupp@adacore.com>
21452 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
21454 2006-02-13 Javier Miranda <miranda@adacore.com>
21456 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
21457 handles default-initialized components to keep separate the management
21458 of this feature but also avoid the unrequired resolution and
21459 expansion of components that do not have partially initialized
21461 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
21462 (Check_Bounds): Likewise.
21463 (Check_Length): Likewise.
21465 2006-02-13 Javier Miranda <miranda@adacore.com>
21466 Ed Schonberg <schonberg@adacore.com>
21468 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
21469 abstract interface type call analyze_and_resolve to expand the type
21470 conversion into the corresponding displacement of the
21471 reference to the base of the object.
21472 (Eval_Attribute, case Width): For systems where IEEE extended precision
21473 is supported, the maximum exponent occupies 4 decimal digits.
21474 (Accessibility_Message): Add '\' in 2-line warning message.
21475 (Resolve_Attribute): Likewise.
21476 (case Attribute_Access): Significantly revise checks
21477 for illegal access-to-subprogram Access attributes to properly enforce
21478 the rules of 3.10.2(32/2).
21479 Diagnose use of current instance with an illegal attribute.
21481 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
21483 (Enclosing_Generic_Unit): New function to return a node's innermost
21484 enclosing generic declaration node.
21485 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
21486 (Type_Access_Level): The accessibility level of anonymous acccess types
21487 associated with discriminants is that of the current instance of the
21488 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
21489 (Compile_Time_Constraint_Error): Handle case of conditional expression.
21490 (Kill_Current_Values_For_Entity): New function
21491 (Enter_Name): Change formal type to Entity_Id
21493 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
21494 Ed Schonberg <schonberg@adacore.com>
21495 Gary Dismukes <dismukes@adacore.com>
21497 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
21498 Analyze_Compilation_Unit.
21499 Detect and warn on redundant with clauses detected in a package spec
21500 and/or body when -gnatwr is used.
21501 (Analyze_Context): Analyze config pragmas before other items
21502 (Install_Context_Items): Don't analyze config pragmas here
21503 (Install_Limited_Withed_Unit): Set limited entity of package in
21504 with_clause so that cross-reference information or warning messages on
21505 unused packages can be properly generated
21506 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
21507 has Error_Posted set. Prevent infinite loops in illegal programs.
21508 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
21509 to the point of the error test requiring the current unit to be private.
21510 This ensures that private with clauses are not exempted from the basic
21511 checking for being a descendant of the same library unit parent as a
21512 withed private descendant unit.
21513 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
21514 handle private with clauses properly, as well as to account for cases
21515 where the withed unit is a public descendant of a private ancestor
21516 (in which case the current unit must be a descendant of the private
21517 ancestor's parent). The spec comments were updated accordingly. Also,
21518 the old error message in this subprogram was replaced with error
21519 messages that mirror the errors tested and reported by
21520 Check_Private_Child_Unit.
21521 Parameter and variable names improved for readability.
21522 (Install_Limited_Context_Clauses): Remove test for a withed unit being
21523 private as the precondition for calling
21524 Check_Private_Limited_Withed_Unit since that subprogram has been
21525 revised to test public units as well as private units.

21530 Javier Miranda <miranda@adacore.com>
21532 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
21533 that Scope_Stack.First = 1.
21534 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21535 were not always properly handled previously.
21536 (Formal_Entity): Complete rewrite, to handle properly some complex case
21537 with multiple levels of parametrization by formal packages.
21538 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
21539 to the corresponding derived type declaration for proper semantics.
21541 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
21542 (Check_Component): Enforce restriction on components of
21543 unchecked_unions: a component in a variant cannot contain tasks or
21545 (Unchecked_Union): Allow nested variants and multiple discriminants, to
21547 Add pragma Ada_2005 (synonym for Ada_05)
21548 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21549 were not always properly handled previously.
21550 Document that pragma Propagate_Exceptions has no effect
21551 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
21552 (Set_Convention_From_Pragma): Check that if a convention is
21553 specified for a dispatching operation, then it must be
21554 consistent with the existing convention for the operation.
21555 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
21556 longer required to specify an vtable-ptr component in the record. For
21557 compatibility reasons we leave the support for the previous definition.
21558 (Analyze_Pragma, case No_Return): Allow multiple arguments
21560 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
21561 non-overrideen inherited operation with a controlling result as
21562 illegal only its implicit declaration comes from the derived type
21563 declaration of its result's type.
21564 (Check_Possible_Deferred_Completion): Relocate the object definition
21565 node of the subtype indication of a deferred constant completion rather
21566 than directly analyzing it. The analysis of the generated subtype will
21567 correctly decorate the GNAT tree.
21568 (Record_Type_Declaration): Check whether this is a declaration for a
21569 limited derived record before analyzing components.
21570 (Analyze_Component_Declaration): Diagnose record types not explicitly
21571 declared limited when a component has a limited type.
21572 (Build_Derived_Record_Type): Code reorganization to check if some of
21573 the inherited subprograms of a tagged type cover interface primitives.
21574 This check was missing in case of a full-type associated with a private
21576 (Constant_Redeclaration): Check that the subtypes of the partial and the
21577 full view of a constrained deferred constant statically match.
21578 (Mentions_T): A reference to the current type in an anonymous access
21579 component declaration must be an entity name.
21580 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
21581 class_wide type to refer to full type, not to the incomplete one.
21582 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
21583 available. Required to give support to the certified run-time.
21584 (Analyze_Component_Declaration): In case of anonymous access components
21585 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
21586 (Process_Discriminants): For an access discriminant, use the
21587 discriminant specification as the associated_node_for_itype, to
21588 simplify accessibility checks.
21590 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21591 Javier Miranda <miranda@adacore.com>
21593 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
21594 abstract interpretations on an operator, remove interpretations that
21595 yield Address or a type derived from it, if one of the operands is an
21597 (Try_Object_Operation.Try_Primitive_Operation,
21598 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
21599 location when creating the new reference to a primitive or class-wide
21600 operation as a part of rewriting a subprogram call.
21601 (Try_Primitive_Operations): If context requires a function, collect all
21602 interpretations after the first match, because there may be primitive
21603 operations of the same type with the same profile and different return
21604 types. From code reading.
21605 (Try_Primitive_Operation): Use the node kind to choose the proper
21606 operation when a function and a procedure have the same parameter
21608 (Complete_Object_Operation): If formal is an access parameter and prefix
21609 is an object, rewrite as an Access reference, to match signature of
21610 primitive operation.
21611 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21612 by an expanded name with prefix Standard, when the operands are of an
21613 anonymous access type.
21614 (Remove_Abstract_Operations): If the operation is abstract because it is
21615 inherited by a user-defined type derived from Address, remove it as
21616 well from the set of candidate interpretations of an overloaded node.
21617 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21620 2006-02-13 Bob Duff <duff@adacore.com>
21622 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21623 redundant use clauses.
21624 In particular, if the scope of two use clauses overlaps, but one is not
21625 entirely included in the other, we should not warn. This can happen
21626 with nested packages.
21627 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21628 reported errors. The bug was reported when the compiler was built
21629 with assertions enabled.
21630 (Find_Type): If the node is a 'Class reference and the prefix is a
21631 synchronized type without a corresponding record, return the type
21634 2006-02-13 Javier Miranda <miranda@adacore.com>
21636 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21637 if this is the full-declaration associated with a private declaration
21638 that implement interfaces, then the private type declaration must be
21640 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21641 as aliased. The use of the 'access attribute is not available for such
21642 object (for this purpose the object should be explicitly marked as
21643 aliased, but being an anonymous type this is not possible).
21645 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21646 Robert Dewar <dewar@adacore.com>
21648 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21649 compilation unit is an elaboration scope.
21650 (Add_Task_Proc): Add '\' in 2-line warning message.
21651 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21653 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21654 Javier Miranda <miranda@adacore.com>
21656 * sem_type.adb (Write_Overloads): Improve display of candidate
21658 (Add_One_Interp): Do not add to the list of interpretations aliased
21659 entities corresponding with an abstract interface type that is an
21660 immediate ancestor of a tagged type; otherwise we have a dummy
21661 conflict between this entity and the aliased entity.
21662 (Disambiguate): The predefined equality on universal_access is not
21663 usable if there is a user-defined equality with the proper signature,
21664 declared in the same declarative part as the designated type.
21665 (Find_Unique_Type): The universal_access equality operator defined under
21666 AI-230 does not cover pool specific access types.
21667 (Covers): If one of the types is a generic actual subtype, check whether
21668 it matches the partial view of the other type.
21670 2006-02-13 Thomas Quinot <quinot@adacore.com>
21672 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21673 line. This is necessary to allow In_Extended_Main_Unit to provide
21674 correct results for itypes while writing out expanded source.
21675 (Close_File): No need to update the source_index_table here since it's
21676 now done for each line.
21678 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21679 Robert Dewar <dewar@adacore.com>
21681 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21682 preserve the source unit where the itype is declared, and prevent a
21684 (Note_Implicit_Run_Time_Call): New procedure
21685 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
21688 * sprint.ads: Document use of $ for implicit run time routine call
21690 2006-02-13 Quentin Ochem <ochem@adacore.com>
21692 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21695 2006-02-13 Bob Duff <duff@adacore.com>
21697 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21698 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21699 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21700 raise Constraint_Error.
21702 * s-vallli.adb (Scan_Long_Long_Integer): Call
21703 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21704 do not scan leading blanks and sign twice.
21705 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21706 raise Constraint_Error.
21708 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21709 Scan_Long_Long_Unsigned): Split out most of the processing from
21710 Scan_Long_Long_Unsigned out into
21711 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21712 This prevents scanning leading blanks and sign twice.
21713 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21716 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21717 out most of the processing from Scan_Unsigned out into
21718 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21719 This prevents scanning leading blanks and sign twice.
21721 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21722 use with Modular'Value attribute.
21723 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

21742 * gnat_rm.texi, gnat_ugn.texi: Remove limitations with sparc m64
21744 Document that gnatbind -M option is for cross environments only.
21745 Added description of using gnatmem to trace gnat rtl allocs and deallocs
21746 Add note on use of $ to label implicit run time calls
21747 Add documentation for -gnatyI (check mode IN)

21921 * a-taster.ads, a-taster.adb: New files.
21923 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21924 link to the version that does nothing. This way the task termination
21925 routine is not executed twice for the environment task when finishing
21926 because of an unhandled exception.
21928 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21929 handler because of an unhandled exception.
21931 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

21937 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21938 non-tasking version of the soft link for task termination. We do
21939 nothing since if we are using the non-tasking version it
21940 means that the task termination functionality is not used.
21941 (Null_Finalize_Global_List): Add this null version for the procedure
21942 in charge of finalizing the global list for controlled objects.
21943 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21944 instead for handling run-time termination in a more flexible way.
21945 (Adafinal_NT): This new procedure will take care of finalizing the
21946 global list for controlled objects if needed, but no tasking
21949 * s-tarest.adb (Task_Lock): Do not try to lock again the
21950 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21951 some run-time operations.
21952 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21953 until all nested locks have been released.
21954 (Task_Wrapper): Call the fall-back task termination handler. It
21955 applies to all tasks but the environment task.
21956 (Finalize_Global_Tasks): Add the call for the task termination
21957 procedure for the environment task.
21958 (Task_Wrapper): suppress warnings around declaration of
21959 Secondary_Stack_Address.
21961 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21962 moved to the Common_ATCB record.
21963 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21964 Common_ATCB record.
21965 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21966 Common_ATCB record.
21968 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21969 Fall_Back_Handler, and Specific_Handler.
21971 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21972 defined in Ada.Task_Termination, to avoid circular dependencies.
21973 (Termination_Handler): Redefine this type here, alredy defined in
21974 Ada.Task_Termination, for avoiding circular dependencies.
21975 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21976 for storing task termination handlers. In addition,
21977 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21978 Common_ATCB because it is used by both the regular and the restricted
21980 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21981 Common_ATCB because it is used by both the regular and the restricted
21983 (Common_ATCB): Added a dynamic task analyzer field.
21985 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21986 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21987 (Task_Wrapper): Call the task termination handler. It applies to all
21988 tasks but the environment task.
21989 (Finalize_Global_Tasks): Call the task termination procedure for the
21990 environment task. The call to Finalize_Global_List is now performed
21991 using the soft links mechanism.
21992 (Task_Wrapper): added dynamic stack analysis.
21994 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21995 potentially blocking operations has been moved from
21996 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21997 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21998 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21999 this run-time check.
22001 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
22002 of task termination procedure.
22003 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

22045 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
22046 to the specification because the frontend generates code that uses this
22048 (Set_Interface_Table): Add missing assertion.
22049 Update documentation describing the run-time structure.
22050 (Displace): New subprogram that displaces the pointer to the object
22051 to reference one of its secondary dispatch tables.
22052 (IW_Membership): Modified to use the new table of interfaces.
22053 (Inherit_TSD): Modified to use the new table of interfaces.
22054 (Register_Interface_Tag): Use the additional formal to fill the
22055 contents of the new table of interfaces.
22056 (Set_Interface_Table): New subprogram that stores in the TSD the
22057 pointer to the table of interfaces.

22071 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
22072 in all the calls to Expand_Interface_Thunk. Instead of referencing the
22073 record component containing the tag of the secondary dispatch table we
22074 have to use the Offset_To_Top run-time function to get this information;
22075 otherwise if the pointer to the base of the object has been displace
22076 we get a wrong value if we use the 'position attribute.
22078 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
22079 all the calls to Expand_Interface_Thunk.
22080 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
22081 interfaces; hence the call to Set_Interface_Table was clearly wrong.

22083 ensure that the interfaces implemented by the ancestors are placed
22084 at the header of the generated list.
22085 (Expand_Interface_Conversion): Handle the case in which the displacement
22086 associated with the interface conversion is not statically known. In
22087 this case we generate a call to the new run-time subprogram Displace.
22088 (Make_DT): Generate and fill the new table of interfaces.
22089 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
22090 Get_Tagged_Kind and Set_Tagged_Kind.
22091 (Tagged_Kind): New function that determines the tagged kind of a type
22092 with respect to limitedness and concurrency and returns a reference to
22094 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
22095 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
22096 primary dispatch table for a type.

22098 secondary dispatch table respectively of a tagged type.
22100 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
22101 (Expand_Interface_Conversion): New subprogram to indicate if the
22102 displacement of the type conversion is statically known.

22112 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
22113 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
22114 RE_TK_Tagged, RE_TK_Task.
22116 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
22117 Init_Secondary_Tags_Internal to allow its use with interface types and
22118 also to generate the code for the new additional actual required
22119 by Set_Offset_To_Top.
22120 (Build_Init_Statements): In case of components associated with abstract
22121 interface types there is no need to generate a call to its IP.
22122 (Freeze_Record_Type): Generate Select Specific Data tables only for
22124 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
22125 the bodies and specifications of the predefined primitive operations
22126 dealing with dispatching selects and abort, 'Callable, 'Terminated only
22127 for concurrent types.
22129 * exp_sel.ads, exp_sel.adb: New files.
22131 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
22132 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
22133 properly protected objects and attach handler in the case of the
22134 restricted profile.
22135 Move embeded package Select_Expansion_Utilities into a separate external

22138 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
22139 (Build_K, Build_S_Assignment): New subprograms, part of the select
22140 expansion utilities.

22143 where the trigger is a dispatching procedure of a limited tagged type.
22145 2005-12-09 Olivier Hainque <hainque@adacore.com>
22147 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
22148 pointer initialization values. Make a SAVE_EXPR instead. Add comments
22149 about the use and expansion of SAVE_EXPRs in the various possible
22150 renaming handling cases.
22151 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
22152 abusing DECL_FCONTEXT.

22252 covered by the tag of the source.
22254 2005-12-09 Robert Dewar <dewar@adacore.com>
22256 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

22271 component associated with the secondary table of an abstract interface
22272 type, return the entity associated with such abstract interface type.
22273 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
22274 base type to create anonymous subtype, because entity may be a locally
22275 declared subtype or generic actual.
22276 (Find_Interface): New subprogram that given a tagged type and one of its
22277 component associated with the secondary table of an abstract interface
22278 type, return the entity associated with such abstract interface type.
22280 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
22281 conversion cannot be handled at compile time. In this case we pass this
22282 information to the expander to generate the appropriate code.

22317 copied component does not have a known static Esize, then reset
22318 the size and positional fields of the new component.
22319 (Analyze_Component_Declaration): A limited component is
22320 legal within a protected type that implements an interface.
22321 (Collect_Interfaces): Do not add to the list the interfaces that
22322 are implemented by the ancestors.
22323 (Derived_Type_Declaration): If the parent of the full-view is an
22324 interface perform a transformation of the tree to ensure that it has
22325 the same parent than the partial-view. This simplifies the job of the
22326 expander in order to generate the correct object layout, and it is
22327 needed because the list of interfaces of the full-view can be given in
22329 (Process_Full_View): The parent of the full-view does not need to be
22330 a descendant of the parent of the partial view if both parents are
22332 (Analyze_Private_Extension_Declaration): If declaration has an explicit
22333 "limited" the parent must be a limited type.

22347 (Process_Full_View): Improve the check for the "no hidden interface"
22348 rule as defined by AI-396.
22350 2005-12-09 Robert Dewar <dewar@adacore.com>
22352 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
22353 types, not on record subtypes.
22354 (Freeze_Entity): Code cleanup. Add barrier to the loop
22355 that generates the references for primitive operations. This allows to
22356 remove an unnecessary exception handler.

22363 source on the command line, call gnatcheck with all the compilable
22364 sources of the project.
22365 Take into account the new command Check, for gnatcheck. Treat as for

22407 available user-specified stream attributes on limited parameters to
22408 also test the type directly rather than only its underlying type (for
22409 Ada 95) and, in the case of Ada 2005, to check that the user-specified
22410 attributes are visible at the point of the subprogram declaration.
22411 For Ada 2005, the error message is modified to indicate that the
22412 type's stream attributes must be visible (again, only for -gnat05).

22444 types use the corresponding record type. This was not needed before
22445 the implementation of Ada 2005 synchronized types because
22446 concurrent types were never tagged types in Ada 95.

22574 * socket.c: Add extern int h_errno for rtems since networking header
22575 files are not available at this point in a tool bootstrap. Newlib

22579 Roger Sayle <roger@eyesopen.com>
22582 * misc.c (internal_error_function): Don't use vsprintf to format
22583 the error message text, instead use pp_format_text and the new

22595 a temporary if taking the address of something that is neither
22596 reference, declaration, or constant, since the gimplifier
22597 can't handle that case.
22599 2005-11-17 Laurent Guerby <laurent@guerby.net>
22602 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

22669 * gen-soccon.c: Complete value expansion should not be performed on
22670 TARGET, as it has the form of a math expression, and some components
22671 may be platform-defined macros.
22672 For VxWorks, generate the OK and ERROR values.
22673 New constants giving the sizes of the components of C struct timeval.

22679 * types.ads: Include All_Checks in Suppress_Array
22681 * checks.adb (Check_Needed): Remove kludge for a/=b rewritten as
22682 not(a=b), since we no longer do this rewriting, and hence it is not
22684 (Elaboration_Checks_Suppressed): Add special casing to
22685 deal with different cases of static and dynamic elaboration checks (all
22686 checks does not count in the first case, but does in the second).
22687 (Expr_Known_Valid): Do not assume that the result of any arbitrary
22688 function call is valid, since this is not the case.
22689 (Ensure_Valid): Do not apply validity check to a real literal
22690 in a universal or fixed context
22692 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
22693 elementary types using the operator in standard. It is cleaner not to
22694 modify the programmers intent, especially in the case of floating-point.
22695 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
22696 it did not matter because we always rewrote a/=b to not(a=b).
22697 (Expand_Allocator_Expression): For an allocator expression whose nominal
22698 subtype is an unconstrained packed type, convert the expression to its
22699 actual constrained subtype.
22700 Implement warning for <= or >= where < or > not possible
22701 Fix to Vax_Float tests (too early in many routines, causing premature
22702 Vax_Float expansions.
22704 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
22705 to be used with packages and generic packages as well as with
22707 (Suppress): Set All_Checks, but not Elaboration_Check, for case
22708 of pragma Suppress (All_Checks)
22709 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
22710 a string literal for precise control over warnings.
22711 Avoid raise of pragma in case of unrecognized pragma and just return
22714 * sem_prag.ads: Minor reformatting
22716 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
22717 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter
22718 Switch. Do not handle any exception.
22719 Include -gnatwx as part of -gnatg (warn on redundant parens)
22720 Allow optional = after -gnatm
22721 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22722 longer sets Elaboration_Checks.
22723 Code to set warning mode moved to Sem_Warn
22724 so that it can be shared by pragma processing.
22726 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
22729 * s-taprop-solaris.adb:
22730 Change some <= to =, to avoid new warning

22734 Fix obvious typo (Total_Errors_Detected <= 0 should be = 0)
22736 2005-11-14 Robert Dewar <dewar@adacore.com>
22738 * exp_vfpt.adb: Handle /= case
22739 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22747 Increase default priority on Lynx from 15 to 17, and meet the Ada
22748 requirement that Default_Priority be ((Priority'First +
22749 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

22851 we are not defining the type.
22852 <E_Record_Type>: Likewise.
22853 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22854 to get advantage of the new maybe_stabilize_reference interface, to
22855 ensure that what we reference is indeed stabilized instead of relying
22856 on assumptions on what the stabilizer does.
22857 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22858 type imported through a limited_with clause, use its non-limited view.
22859 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22861 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22862 of #if sections + explicit comparisons of convention identifiers.

22864 before early-returning for certain types when code generation is
22866 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
22867 nullification of gnu_expr we do for objects with address clause and
22868 that we are not defining.
22869 (elaborate_expression_1): Do not create constants when creating
22870 variables needed by the debug info: the dwarf2 writer considers that
22871 CONST_DECLs is used only to represent enumeration constants, and emits
22873 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22874 object with an address clause into an indirect reference, drop the
22875 initializing expression.

22887 subtype to build an actual type with bounds template.
22888 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22889 is provided by the front-end, use that subtype to compute the size of
22890 the deallocated object.

22892 check for a potential violation of a No_Elaboration_Code restriction.

22897 maybe_stabilize, for common uses without restriction on lvalues and
22898 without need to check for the success indication.
22899 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22900 pass false instead of 0 as the FORCE argument which is a bool.
22901 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22902 attached to a renaming pointer has been properly stabilized, as no such
22903 object is attached otherwise.
22904 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22905 function uses the "target pointer" return mechanism.
22906 Reinstate conversion of the actual to the type of the formal
22907 parameter before any other specific treatment based on the passing
22908 mechanism. This turns out to be necessary in order for PLACEHOLDER
22909 substitution to work properly when the latter type is unconstrained.

22913 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

22917 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22918 static output of record constructor if all the components are constant.
22919 (gnat_build_constructor): For a record type, sort the list of field
22920 initializers in increasing bit position order.
22921 Factor common code to build a storage type for an unconstrained object
22922 from a fat or thin pointer type and a constrained object type.
22923 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22924 types variants, and process special cases of VIEW_CONVERT expressions
22925 as their NOP_EXPR counterpart to ensure we get to the
22926 CORRESPONDING_VARs associated with CONST_DECls.
22927 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22928 on the right-hand side.
22930 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring

22933 are converting back to its original type.
22934 (convert) <JM input>: Fallthrough regular conversion code instead of
22935 extracting the object if converting to a type variant.
22936 (create_var_decl): When a variable has an initializer requiring code
22937 generation and we are at the top level, check for a potential violation
22938 of a No_Elaboration_Code restriction.
22939 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22940 SIZE and SIZE_UNIT which we need for later back-annotations.

22943 is an unchecked union.

22945 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22946 main variant, just replace the VIEW_CONVERT_EXPR.

23122 and related): For a prefix that is an explicit dereference of an
23123 access to unconstrained packed array type, annotate the dereference
23124 with an actual subtype so GIGI can make a correct size computation.
23125 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
23126 'Unrestricted_Access, if the designated type is an interface we
23127 add a type conversion to force the displacement of the pointer
23128 to the secondary dispatch table.
23129 Use Universal_Real instead of Long_Long_Float when we need a high
23130 precision float type for the generated code (prevents gratuitous
23131 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
23132 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
23133 'Terminated for task interface class-wide objects. Generate a call to
23134 the predefined dispatching routine used to retrieve the _task_id from
23135 a task corresponding record.

23155 assignment of a value of a tagged type that has been rewritten to a

23159 (Expand_N_If_Statement): When killing a dead then-branch in an
23160 if-statement that has elsif_parts, recompute the Current_Value node
23161 for any entity whose value is known from the condition of the first
23163 (Expand_N_Return_Statement): When returning a mutable record, convert
23164 the return value into its actual subtype in order to help the backend
23165 to return the actual size instead of the maximum. This is another
23166 aftermath of not returning mutable records on the sec-stack anymore.
23168 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
23169 handling of error msg for suspicious reverse range iteration.

23185 a process handle, not need to convert.
23186 (__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.
23188 * g-expect.adb: (Kill): Document the new close parameter.
23189 (Close): Do not release the process handle in the kill there as

23191 (Send_Signal): Release the process handle.
23193 2005-11-14 Robert Dewar <dewar@adacore.com>
23195 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

23496 In addition some minor reorganization of the code has been done to
23497 leave it more clear.
23498 (Analyze_Type_Declaration): If type has previous incomplete tagged
23499 partial view, inherit properly its primitive operations.

23555 whose default is abstract because the object type itself is abstract.
23556 (Find_Type): If the type is incomplete and appears as the prefix of a
23557 'Class reference, it is tagged, and its list of primitive operations
23558 must be initialized properly.

23588 statement to inhibit warning.
23589 (Resolve_Unary_Op): Do not produce a warning when
23590 processing an expression of the form -(A mod B)

24414 * g-soccon-vms.adb: Renamed to g-soccon-vms.ads
24416 * g-soccon-vms.ads: Renamed from g-soccon-vms.adb
24418 * g-soccon.ads, g-soccon-tru64.ads, g-soccon-aix.ads,

24420 g-soccon-solaris.ads, g-soccon-mingw.ads, g-soccon-vxworks.ads,
24421 g-soccon-freebsd.ads: Add new constants:
24423 SO_RCVTIMEO/SO_SNDTIMEO
24427 Move all target-specific file inclusions and macro definitions to
24428 gsocket.h, in order to ensure that any C code in socket.c will see a
24429 set of constants that is consistent with the contents of g-soccon.ads.
24431 * gsocket.h: Code imported from gen-soccon.c:
24432 Move all target-specific file inclusions and macro definitions to
24433 gsocket.h, in order to ensure that any C code in socket.c will see a set
24434 of constants that is consistent with the contents of g-soccon.ads.
24435 This change also makes gen-soccon self-contained (removing dependencies
24436 upon GCC internal headers).
24438 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
24440 (To_Inet_Addr): Now a procedure instead of a function, more efficient.

24572 Javier Miranda <miranda@adacore.com>
24574 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
24575 from object notation, the original node is unanalyzed and carries no
24576 semantic information, so that accessiblity checks must be performed on
24577 the type of the actual itself.

24598 2005-09-01 Nicolas Setton <setton@adacore.com>
24600 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types

24632 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
24633 position set is provided, we compute one in order to reduce the maximum
24634 length of the keys. This computation first selects a character
24635 position between 1 and the minimum length of the keys in order to
24636 avoid reducing one of the keys to an empty string.
24637 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24638 does not converge. The initialization procedure now comes with a
24639 maximum number of iterations such that when exceeded, an exception is
24640 raised in Compute. The user can initialize this ratio to another value

24650 to keep the association between the two entities.
24651 Update copyright notice

24797 Ed Schonberg <schonberg@adacore.com>
24799 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24800 become local to the whole package.
24801 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24802 the package was already analyzed the new algorithm "replaces" the
24803 real entities by the shadow ones. This is required to ensure that
24804 the order of these entities in the homonym chains does not change;
24805 otherwise we can have undefined references at linking time because
24806 in case of conflicts the external name of the entities will have
24807 a suffix that depends on the order of the entities in the chain.
24808 (Remove_Limited_With_Clause): Complementary code that completes the
24809 new algorithm and replaces the shadow entities by the real ones.
24810 (Install_Limited_Withed_Unit): When unchaining entities before the
24811 installation of the shadow entities, only regular entities of the
24812 public part must be taken into account. This is required to
24813 keep this routine in synch with the work done by Remove_Limited_
24815 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24816 even if unit is analyzed, because the analysis of the unit is
24817 idempotent in any case, and the limited view of the unit may have to
24818 be installed for proper visibility.
24819 (Expand_Limited_With_Clause): Even if the unit in the implicit
24820 with_clause has been analyzed already, a limited view of the package
24821 must be built for the current context, if it does not exist yet.

24824 Javier Miranda <miranda@adacore.com>
24825 Gary Dismukes <dismukes@adacore.com>
24827 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24828 defining entity for the instance body, make a new defining identifier
24829 rather than copying the entity of the spec, to prevent accidental
24830 sharing of the entity list.
24831 (Check_Private_View): When exchanging views of private types, build the
24832 list of exchanged views as a stack, to ensure that on exit the exchanges
24833 are undone in the proper order.
24834 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24835 Restore the compilation environment in case of instantiation_error.
24836 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24837 for an anonymous access result.
24838 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24839 (Formal_Entity): Handle properly the case of a formal package that
24840 denotes a generic package renaming.
24842 2005-09-01 Thomas Quinot <quinot@adacore.com>
24844 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24845 clause if the array aggregate is surrounded by parentheses.
24847 2005-09-01 Cyrille Comar <comar@adacore.com>
24848 Gary Dismukes <dismukes@adacore.com>
24849 Ed Schonberg <schonberg@adacore.com>
24850 Javier Miranda <miranda@adacore.com>
24852 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24854 to check if a type is Constrained in cases related to code generation
24855 (rather than semantic checking) since otherwise we do not generate
24856 similar code for mutable private types depending if their
24857 discriminants are visible or not.
24858 (Check_Abstract_Overriding): Do not complain about failure to override
24859 the primitive operations used in dispatching selects since they will
24860 always be overriden at the freeze point of the type.
24861 (Access_Definition): Separate out handling for resetting the scope
24862 of an anonymous access function result type. Retrieve the scope
24863 of the associated function rather than using Current_Scope, which
24864 does not have a consistent value (depends on whether we're in the
24865 middle of analyzing formal parameters). Add ??? comment about
24866 finding a cleaner way to handle the special cases of scope setting.
24867 (Process_Incomplete_Dependents): A protected operation is never a
24868 dispatching operation (only its wrapper may be).
24869 (Build_Derived_Record_Type): In case of tagged private types that
24870 implement interfaces add derivation of predefined primitive
24872 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24873 by two parameters that are used in case of derivation from abstract
24874 interface types: No_Predefined_Prims is used to avoid the derivation
24875 of predefined primitives from the interface, and Predefined
24876 Prims_Only is used to complete the derivation predefined primitives
24877 in case of private tagged types implementing interfaces.
24878 Fix typo in comments
24879 (Find_Interface_In_Descendant): Protect the frontend against
24880 wrong code with large circularity chains.
24881 (Is_Private_Overriding): Add support for entities overriding interface
24882 subprograms. The test failed because Entities associated with overriden
24883 interface subprograms are always marked as hidden (and used to build
24884 the secondary dispatch table); in this case the overriden entity is
24885 available through the field abstract_interface_alias (cf. override_
24886 dispatching_operation)
24887 (Access_Definition): Set the scope of the type to Current_Scope for the
24888 case of a function with an anonymous access result type.
24889 (Access_Subprogram_Declaration): Handle creation of the type entity for
24890 an access-to-function type with an anonymous access result.
24891 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24892 in handling for N_Access_Function_Definition.
24893 (Analyze_Subtype_Declaration): Modify the text of error message.
24894 (Derived_Type_Declaration): Modify the text of error message.
24895 (Process_Subtype): Modify the text of error message plus cleanup
24896 of one redundant error message.
24897 (Analyze_Component_Declaration): Code cleanup.
24898 (Analyze_Object_Declaration): Code cleanup.
24899 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24900 attribute in case of access types. Code cleanup.
24901 (Array_Type_Declaration): Code cleanup.
24902 (Process_Discriminants): Create the new null-excluding itype
24903 if required. Code cleanup.
24904 (Process_Subtype): Create the new null-excluding itype if
24905 required. Code cleanup.
24906 (Build_Derived_Record_Type): Code cleanup to avoid calling
24907 twice the subprogram derive_subprograms in case of private
24908 types that implement interfaces. In this particular case the
24909 subprogram Complete_Subprograms_Derivation already does the
24910 job associated with the second call.
24912 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24913 conversion to the full view when generating an operation for a
24914 discriminant whose type may currently be private.
24916 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24917 Javier Miranda <miranda@adacore.com>
24919 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24920 V (Obj.F), the rewriting does not involve the indexed component, but
24921 only the selected component itself.
24922 Do not apply the transformation if the analyzed node is an actual of a
24923 call to another subprogram.
24924 (Complete_Object_Operation): Retain the entity of the
24925 dispatching operation in the selector of the rewritten node. The
24926 entity will be used in the expansion of dispatching selects.
24927 (Analyze_One_Call): Improve location of the error message associated
24929 (Analyze_Selected_Component): No need to resolve prefix when it is a
24930 function call, resolution is done when parent node is resolved, as
24932 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24933 when attempting to resolve a call transformed from its object notation.
24934 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24935 of the argument list for each interpretation of the operation.
24936 (Try_Object_Operation): The designated type of an access parameter may
24937 be an incomplete type obtained through a limited_with clause, in which
24938 case the primitive operations of the type are retrieved from its full
24940 (Analyze_Call): If this is an indirect call, and the return type of the
24941 access_to_subprogram is incomplete, use its full view if available.
24943 2005-09-01 Javier Miranda <miranda@adacore.com>
24944 Gary Dismukes <dismukes@adacore.com>
24946 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24947 access types the null-exclusion and access-to-constant attributes must
24949 (Analyze_Return_Statement): When the result type is an anonymous access
24950 type, apply a conversion of the return expression to the access type
24951 to ensure that appropriate accessibility checks are performed.
24952 (Analyze_Return_Type): For the case of an anonymous access result type,
24953 generate the Itype and set Is_Local_Anonymous_Access on the type.
24954 Add ??? placeholder for check to disallow returning a limited object
24955 in Ada 2005 unless it's an aggregate or a result of a function call.
24956 Change calls from Subtype_Mark to Result_Definition.
24957 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24958 Result_Definition in call to Make_Function_Specification.
24959 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24960 Set_Result_Definition.
24961 (Make_Inequality_Operator): Change formal Subtype_Mark to
24962 Result_Definition in call to Make_Function_Specification.
24963 (Process_Formals): Create the new null-excluding itype if required.
24964 (New_Overloaded_Entity): For an entity overriding an interface primitive
24965 check if the entity also covers other abstract subprograms in the same
24966 scope. This is required to handle the general case, that is, overriding
24967 other interface primitives and overriding abstract subprograms inherited
24968 from some abstract ancestor type.
24969 (New_Overloaded_Entity): For an overriding entity that comes from
24970 source, note the operation that it overrides.
24971 (Check_Conformance, Type_Conformant): Addition of one new formal
24972 to skip controlling formals in the analysis. This is used to
24973 handle overloading of abstract interfaces.
24974 (Base_Types_Match): Add missing case for types imported from
24975 limited-with clauses
24976 (New_Overloaded_Entity): Add barrier to protect the use of
24977 the "alias" attribute.
24979 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24981 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24982 verify that the procedure and the entry are mode conformant.
24983 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24984 as a different operator, which is often a cut-and-paste error.
24986 2005-09-01 Javier Miranda <miranda@adacore.com>
24987 Ed Schonberg <schonberg@adacore.com>
24989 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24990 used in controlling parameters exclude null because it is necessary to
24991 read the tag to dispatch, and null has no tag.
24992 (Override_Dispatching_Operation): If the previous operation is inherited
24993 from an interface, it becomes hidden and does not participate in later
24996 2005-09-01 Javier Miranda <miranda@adacore.com>
24997 Ed Schonberg <schonberg@adacore.com>
24998 Gary Dismukes <dismukes@adacore.com>
25000 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
25001 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
25002 the expander will generate the corresponding run-time check to evaluate
25004 (Resolve_Call): Check for legal type of procedure name or prefix that
25005 appears as a trigger in a triggering alternative.
25006 (Valid_Conversion): If expression is ambiguous and the context involves
25007 an extension of System, remove System.Address interpretations.
25008 (Resolve_Qualified_Expression): Reject the case of a specific-type
25009 qualification applied to a class-wide argument. Enhance comment
25010 to explain checking of Original_Node.
25011 (Resolve_Type_Conversion): The location of the error message was not
25012 general enough to handle the general case and hence it has been removed.
25013 In addition, this patch improves the text of the message.
25014 (Resolve_Type_Conversion): Add missing support for access to interface
25016 (Resolve_Type_Conversion): If the target is a class-wide interface type,
25017 do not expand if the expression is the actual in a call, because proper
25018 expansion will take place when the call itself is expanded.
25019 (Resolve_Allocator): If the context is an unchecked conversion, the
25020 allocator inherits its storage pool, if any, from the target type of
25023 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25024 Javier Miranda <miranda@adacore.com>
25026 * sem_type.adb (Add_One_Interp): If a candidate operation is an
25027 inherited interface operation that has an implementation, use the
25028 implementation to avoid spurious ambiguities.
25029 (Interface_Present_In_Ancestor): In case of concurrent types we can't
25030 use the Corresponding_Record_Typ attribute to look for the interface
25031 because it is set by the expander (and hence it is not always
25032 available). For this reason we traverse the list of interfaces
25033 (available in the parent of the concurrent type).
25034 (Interface_Present_In_Ancestor): Handle entities from the limited view
25036 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25038 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
25039 from the list of required components.
25040 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
25041 primitive procedure of a limited interface with a controlling first
25043 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
25045 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
25046 capture if it is generated in the second operand of a short-circuit
25048 Do not capture values for variables with address clauses.
25049 (Is_Object_Reference): Treat a function call as an object reference only
25050 if its type is not Standard_Void_Type.
25052 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25054 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
25055 to a variable that is statically known to be constant.
25057 2005-09-01 Geert Bosch <bosch@adacore.com>
25058 Robert Dewar <dewar@adacore.com>
25060 * ttypef.ads (VAXDF_Safe_First): Use correct value for constant.

25067 Document that bounds of result of Base_Name match the input index
25069 Add documentation on environment variable syntax for Expand_Path
25071 * gnat_ugn.texi: Update documentation to include mention of -m switches
25072 Document new treatment of wide characters in max line length
25074 Remove -gnatL/-gnatZ switches, no longer used.
25075 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
25078 * gnat_rm.texi: Add doc for two argument form of pragma
25079 Float_Representation.
25080 Add documentation for pragma No_Strict_Aliasing
25081 Add note that explicit component clause overrides pragma Pack.
25082 Add documentation of pragma Debug_Policy

25095 Note that the platform-specific version of g-soccon.ads for VMS is now
25096 named g-soccon-vms.ads (it was previously g-soccon-vms.adb, although it

25837 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25838 longer protected objects. They have been replaced by lower-level
25839 suspension objects made up by a mutex and a condition variable (or
25840 their equivalent given a particular OS) plus some internal data to
25841 reflect the state of the suspension object.
25842 (Initialize, Finalize): Add this initialization procedure for
25843 Suspension_Object, which is a controlled type.
25844 (Finalize): Add the finalization procedure for Suspension_Object,
25845 which is a controlled type.
25847 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
25848 Ada.Synchronous_Task_Control because there is no longer a need for a

25854 (InitializeCriticalSection, EnterCriticalSection,
25855 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25856 pCriticalSection by an anonymous access type so that we avoid problems
25857 of accessibility to local objects.

25863 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
25864 set the environment task mask here.
25865 (Current_State): Add this function that returns the state of the
25867 (Set_False): Add this procedure that sets the state of the suspension
25869 (Set_True): Add this procedure that sets the state of the suspension
25870 object to True, releasing the task that was suspended, if any.
25871 (Suspend_Until_True): Add this procedure that blocks the calling task
25872 until the state of the object is True. Program_Error is raised if
25873 another task is already waiting on that suspension object.
25874 (Initialize): Add this procedure for initializing the suspension
25875 object. It initializes the mutex and the condition variable which are
25876 used for synchronization and queuing, and it sets the internal state
25878 (Finalize): Add this procedure for finalizing the suspension object,
25879 destroying the mutex and the condition variable.

25884 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
25885 which provides a low-level abstraction (using operating system
25886 primitives) for Ada.Synchronous_Task_Control.
25887 This object is made up by a mutex (for ensuring mutual exclusion), a
25888 condition variable (for queuing threads until the condition is
25889 signaled), a Boolean (State) indicating whether the object is open,
25890 and a Boolean (Waiting) reflecting whether there is a task already
25891 suspended on this object.

25908 System.Parameters.No_Abort is True.
25910 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
25911 is no longer done in the body of s-taprop

26156 type derivation of private tagged types implementing interfaces.
26157 In this case some interface primitives may have been overriden

26247 * i-cpp.ads, i-cpp.adb:
26248 This package has been left available for compatibility with previous
26249 versions of the frontend. As part of the new layout this is now a

26303 access to subprograms must be recursive.
26304 (Is_Unchecked_Conversion): Improve the test that recognizes
26305 instantiations of Unchecked_Conversion, and allows them in bodies that
26306 are to be inlined by the front-end. When the body comes from an
26307 instantiation, a reference to Unchecked_Conversion will be an
26308 Expanded_Name, even though the body has not been analyzed yet.

26329 object or component (that is, when Is_Local_Anonymous_Access is true).
26330 Prevent the special checks for conversions of access discriminants in
26331 the case where the discriminant belongs to a nonlimited type, since
26332 such discriminants have their accessibility level defined in the same
26333 way as a normal component of an anonymous access type.
26334 (Resolve_Allocator): When an allocator's designated type is a class-wide
26335 type, check that the accessibility level of type given in the
26336 allocator's expression or subtype indication is not statically deeper

26356 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
26357 check on possible violation of restriction No_Direct_Boolean_Operators
26358 until after expansion of operands, to prevent spurious errors when

26661 the "simple_choice" member in a variant record, in accordance with the
26662 description in the package spec: the information output for a constant
26663 should be "S number", not "SS number".
26664 (Get_Encoded_Name): Return at once if not generating code. Avoids name

27364 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

27371 is disabled, the entity denoted by the argument is the access type

27383 denotes a type in the class.
27384 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
27385 of Name_Generic_Dispatching_Constructor.
27387 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

28130 uses of the Access_Disp_Table attribute to reference the first dispatch
28131 table associated with a tagged type. As
28132 part of the implementation of abstract interface types,
28133 Access_Disp_Table has been redefined to contain a list of dispatch
28134 tables (rather than a single dispatch table).
28135 Similarly, upgrade all the references to Tag_Component by the
28136 new attribute First_Tag_Component.
28137 (Find_Inherited_TSS): Moved to exp_tss.

28151 determine the amount of data to be copied.
28153 * par.adb (P_Interface_Type_Definition): New subprogram that parses the

28181 (Task_Body_Procedure): Removed.
28182 (Set_Task_Body_Procedure): Removed.
28183 These subprogram have been removed because the attribute
28184 Task_Body_Procedure has been moved to the corresponding task type
28185 or task subtype entity to leave a field free to store the list
28186 of interfaces implemented by a task (for AI-345)
28187 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
28188 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with

28251 expression to the type of the object when the object is constant.
28252 Reverse defer_debug_incomplete_list before traversing it, so that trees
28253 are processed in the order at which they were added to the list. This
28254 order is important when using the stabs debug format.
28255 If we are deferring the output of debug information, also defer this
28256 output for a function return type.
28257 When adding fields to a record, prevent emitting debug information
28258 for incomplete records, emit the information only when the record is

28297 Expansion_Delayed and handle case when it's inside an
28298 N_Qualified_Expression.
28300 * sem_ch3.adb (Derived_Type_Declaration): New predicate
28301 Comes_From_Generic, to recognize accurately that the parent type in a
28302 derived type declaration can be traced back to a formal type, because
28303 it is one or is derived from one, or because its completion is derived
28305 (Constrain_Component_Type): If component comes from source and has no
28306 explicit constraint, no need to constrain in in a subtype of the
28308 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.

28339 that come from packed arrays).
28340 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the

28344 (Represented_As_Scalar): Fix to work properly with private types
28345 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
28346 accurate estimate. Yields True in far fewer cases than before,
28347 improving the quality of code that depends on this test.
28349 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
28350 over both visible and private declarations to remove them from tree,

28367 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
28368 that appears in the instantiation rather than the internal subtype
28369 generated in the wrapper package, to avoid anomalies in gigi when the
28370 target is derived from a private type whose full view is an access type.
28372 2005-03-15 Robert Dewar <dewar@adacore.com>
28374 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
28376 Add documentation to replace the use of this flag
28377 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
28380 2005-03-15 Thomas Quinot <quinot@adacore.com>
28382 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
28383 here from exp_attr so it can be shared between exp_attr and exp_dist.
28384 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
28385 all TSS names, not a subset thereof, and the previous name introduced
28386 an unnecessarily confusion that a distinction might exist between
28387 "OK" TSS names and some "not OK" TSS names.
28389 2005-03-15 Doug Rupp <rupp@adacore.com>
28391 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
28394 2005-03-15 Pascal Obry <obry@adacore.com>
28395 Eric Botcazou <ebotcazou@adacore.com>
28399 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
28400 when IN_RTS. This is to work around a bootstrap path problem.
28402 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
28403 table and pass it to __gnat_install_SEH_handler().
28404 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
28406 * lang.opt: Fix specification of -fRTS=.
28408 2005-03-15 Doug Rupp <rupp@adacore.com>
28409 Bernard Banner <banner@adacore.com>
28410 Vincent Celier <celier@adacore.com>
28411 Arnaud Charlet <charlet@adacore.com>
28414 This change works fine when gnatlib is built from the gcc directory,
28415 but does not work when using the libada Makefile, since GCC_FOR_TARGET
28416 is not passed to ada/Makefile.in, so more work is needed by a
28417 Makefile/configure expert.
28419 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
28420 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
28421 Setup gnatlink switch -M for x86_64 linux, as it is already setup
28423 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
28424 Run ranlib on libgccprefix.a
28425 Define PREFIX_OBJS for Darwin, to build libgccprefix.
28426 (ADA_INCLUDE_SRCS): Split Ada packages.
28428 2005-03-15 Robert Dewar <dewar@adacore.com>
28430 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
28432 * impunit.adb: Add GNAT.UTF_32
28434 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
28436 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
28437 now uses GNAT.UTF_32).
28439 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
28440 capabilities for categorizing characters using Unicode categories
28442 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28444 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
28445 instantiation that has been rewritten as a package body, retrieve spec
28446 to generate proper name for implicit_with_clause.
28447 (Install_Parents): Recognize a parent that is an instantiation but has
28448 been rewritten as a package declaration during analysis.
28450 2005-03-15 Javier Miranda <miranda@adacore.com>
28451 Ed Schonberg <schonberg@adacore.com>
28453 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
28454 parameter reported some error we immediately return. This improves the
28455 behaviour of the frontend in case of errors.
28456 (Install_Parent, Remove_Parent): Introduce new flag
28457 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
28458 ancestor of a generic child unit, when the child is being instantiated.
28459 (Inline_Instance_Body): If we are compiling the private
28460 part or the body of a child unit, restore the proper visibility of the
28461 parents after compiling the instance body.
28463 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28464 Javier Miranda <miranda@adacore.com>
28467 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
28468 of a private type, in which case it is underlying_type that denotes
28469 the proper task. Also modified to use the new entity attribute
28470 that is directly available in the task type and task subtype entities
28471 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
28472 arrays when other dimensions than the first are constrained by
28473 discriminants of an enclosing record.
28474 (Insert_Explicit_Dereference): If the prefix is an indexed component or
28475 a combination of indexed and selected components, find ultimate entity
28476 and generate the appropriate reference for it, to suppress spurious
28478 (Note_Possible_Modification): If an entity name has no entity, return.
28479 (Is_Variable): A function call never denotes a variable.
28480 (Requires_Transient_Scope): For record types, recurse only on
28481 components, not on internal subtypes that may have been generated for
28482 constrained components.
28484 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28486 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
28487 Eliminated as candidates for resolution. Both efficient, and avoids
28488 anomalies with operators declared in deleted code.
28489 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
28490 expansion is disabled (as when compiling a generic) to prevent spurious
28491 warnings on prefixes of selected components.
28493 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28495 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
28496 attached to a list before checking whether it appears in the private
28497 declarations of the current package.
28498 (Make_Inequality_Operator): Insert declaration in proper declarative
28499 list rather than just setting the Parent field, so that
28500 Is_Private_Declaration can handle it properly.
28502 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28504 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
28505 a renaming a body, check that the renamed subprogram in not intrinsic.
28506 (Find_Direct_Name): If several use_visible entities hide
28507 each other, and the context is a predefined file compiled through
28508 rtsfind, keep only the entity that comes from a predefined file.
28510 2005-03-15 Geert Bosch <bosch@adacore.com>
28512 * s-fatgen.adb (Valid): Extend special exceptions to account for long
28513 long float padding to also cover AMD64 and IA64.
28515 2005-03-15 Gary Dismukes <dismukes@adacore.com>
28517 * s-imgwch.adb: Add with and use of Interfaces.
28518 (Img_Wide_Character): Change type of Val to Unsigned_16.

28836 "dispatching" rather than "primitive" operations, since dispatching
28837 calls are now allowed to abstract formal subprograms (which are not
28839 Char_Literal_Value field is now a Uint
28840 (Resolve_Slice): If the prefix is an access to an unconstrained array,
28841 compute the actual subtype of the designated object to impose the proper
28843 (Resolve_Selected_Component): Do not insert an access check if the
28844 prefix is an access type: such a node is expanded into an explicit
28845 dereference, on which the access check is performed anyway. Removes
28846 expensive duplicate checks.

28850 Add support for wide wide character type
28851 (Resolve_Allocator): Replace the error message on wrong null-exclusion
28852 value by a warning message.
28853 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
28854 as fixed-point, and one of the operands is non-static and universal, it
28855 can only be an illegal exponentiation operation, in which case there is
28856 no real value to retrieve.
28858 * exp_strm.adb: Add support for wide wide character type
28859 (Build_Elementary_Input_Call): Compute the size of the stream element by

28907 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28908 Remove ["0A"] from comment, since it can look like a line terminator.
28909 Currently we don't permit this, but this is under discussion by the
28910 ARG, and it is easy enough to use a different example.

28972 describing the new layout.
28973 (Dispatch_Table): The expander computes the actual array size, allocates
28974 the Dispatch_Table record accordingly, and generates code that displaces
28975 the base of the record after the Typeinfo_Ptr component. The access to
28976 these components is done by means of local functions.
28977 (Offset_To_Top): New function.
28978 (Typeinfo_Ptr): New function.
28979 (Get_TSD): Modified to access the new position of the TSD.

28993 dispatching, setting the controlling status of the formal parameters
28994 and result, and issuing an error if there is no controlling type for
28995 the formal subprogram.
28996 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28997 which is an unclean use of that field, we set the new field

29011 subprogram only if inner one comes from source.
29012 (Analyze_Function_Call): If the call is given in object notation, the

29014 argument list. After analyzing the name, if the call has been rewritten
29015 and the result type is set, no further analysis is needed.
29016 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
29017 mark in function specification, in a context where the formals are
29018 visible and hide outer homographs.
29020 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
29021 as the tagged type for the cases of abstract formal subprograms and
29022 renamings of those. Clean up spec comments.
29023 (Check_Dispatching_Context): Add error message to indicate "abstract
29024 procedure", covering the case of a call to a formal abstract procedure
29025 that has statically tagged operands.
29026 (Check_Dispatching_Call): Check for the case of an actual given by
29027 a tag-indeterminate function call whose type is an ancestor of the
29028 containing call's associated tagged type. This situation can occur
29029 for inherited primitives with function defaults. In this case we
29030 use the tagged type's tag directly as the controlling argument for
29032 (Expand_Call): Name change on call to Expand_Dispatch_Call.
29034 * sprint.adb (Sprint_Node_Actual): Split
29035 N_Formal_Subprogram_Declaration into two alternatives for the new

29134 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
29135 component of an array of arrays in an assignment context, and the
29136 aggregate has component associations that require sliding on
29137 assignment, force reanalysis of the aggregate to generate a temporary
29138 before the assignment.
29139 (Must_Slide): Make global to the package, for use in Gen_Assign.
29141 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29143 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
29144 unchecked union with no inferable discriminants, return a
29145 Raise_Program_Error node, rather than inserting it at the point the

29157 Arnaud Charlet <charlet@adacore.com>
29159 * init.c (__gnat_initialize): Add a new parameter eh which contains the
29160 address of the exception registration. The Win32 version of this
29161 routine calls __gnat_install_SEH_handler() to initialize the SEH
29162 (Structured Exception Handling) handler.
29163 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
29164 SEH (Structured Exception Handling) now.
29165 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
29166 (__gnat_initialize for ppc-vxworks): Adjust comments and the
29167 preprocessor condition protecting the call to the extra eh setup
29168 subprogram, which is only available for the ppc target.

29182 Update copyright notice.
29184 * s-tassta.adb (Task_Wrapper): Declare the exception registration

29214 2005-02-09 Vincent Celier <celier@adacore.com>
29216 * prj-makr.adb (Process_Directory): Put file name in canonical case
29217 before matching against the patterns.
29218 If gnatname has been invoked as <prefix>-gnatname
29219 then invoke the compiler as <prefix>-gcc, not just "gcc".
29221 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29223 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
29224 with expansion disabled. The actual subtype is needed among other
29225 places when the selected component appears in the context of a loop
29226 bound, and denotes a packed array.
29227 (Operator_Check): Always use the first subtype in the
29228 error message, to avoid the appearance of internal base types.
29229 (Transform_Object_Operation): Copy each actual in full
29230 to the parameter associations of the constructed call, rather than
29231 using the shallow copy mechanism of New_Copy_List. This ensures that
29232 the chaining of named associations is done properly.
29233 (Complete_Object_Operation): Rewrite node, rather than
29234 replacing it, so that we can trace back to the original selected
29237 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
29238 and calls that use object notation, if the called function is not
29239 declared in a withed unit, place the elaboration constraint on the
29240 unit in the context that makes the function accessible.
29241 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
29242 imposes an elaboration constraint between two packages.
29244 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29246 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
29247 views of a private type after handling its private dependents, to

29269 Slight fix to documentation of -gnaty with no parameters
29271 * xr_tabls.ads: Add ??? comment for missing overall comment
29273 * xsinfo.adb: Make default file name be sinfo.h, since this is what
29274 we now use by default.
29276 * xsnames.adb: Adjust end of file test to look for five space followed
29277 by '#' instead of six spaces. The format of xsnames.adb was modified
29278 in the last update.
29280 * a-numeri.ads: Add reference to AI-388 for greek letter pi
29283 * clean.adb: Minor reformatting.
29285 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
29286 gnatname.adb: Minor reformatting
29287 Add 2005 to copyright output when utility is run
29289 * csets.adb: Eliminate obsolete comment
29291 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
29294 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
29296 2005-02-09 Sergey Rybin <rybin@adacore.com>
29298 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
29299 the difference between compact and incompact layout and add the record
29300 representation clause to the example illustrating different layouts.
29301 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
29302 component clauses").
29304 2005-02-09 Florian Villoing <villoing@adacore.com>
29306 * gnat_ugn.texi: Fix typos.
29307 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

29609 is to check if two function signatures for a call-site and a callee are
29610 compatible enough for the call to be valid. The underlying purpose is

29664 structure of GARLIC and PolyORB RPC receivers.
29665 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
29667 Simplify elaboration code for RCI packages.
29669 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver

29779 note that it applies to obsolete GNAT features, which was previously
29780 omitted. Second we contrast the behavior with that of the new
29781 Ada 2005 AI-368 restriction No_Obsolescent_Features.
29782 Preliminary rewriting of GNAT & libraries chapter in order to take
29783 into account default project locations & new project manager

30009 (process_attributes): Clear DECL_COMMON again when a section attribute
30011 (finish_record_type): Independently track if RECORD_TYPE has SIZE and/or

30015 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
30016 fields claimed addressable still have to be bitfields. Use
30017 value_factor_p instead of a raw binop construction to check for the

30025 Ed Schonberg <schonberg@adacore.com>
30027 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
30028 with an implicit dereference as its prefix, use
30029 Insert_Explicit_Dereference instead of merely rewriting the prefix into

30031 prefix is generated, if appropriate.
30033 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
30034 dereference is rewritten to an explicit one, generate a reference to
30035 the entity denoted by its prefix using the original prefix node, so

30037 access value, if appropriate.
30039 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
30040 emitting 'assigned but never read' warning on a variable on the basis

30056 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
30057 subprogram which is Imported with convention Intrinsic if an
30058 External_Name argument is specified.
30059 (Process_Import_Or_Interface): Properly diagnose link name argument.

30085 PolyORB_Support.Build_Stub_Type): New subrograms containing the
30086 PCS-specific part of Add_Stub_Type.

30116 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
30117 and the Has_Pragma_Unreferenced flag for each formal before analyzing
30118 the body, to ensure that warnings are properly emitted for each accept
30119 statement of a given task entry.

30141 (Remove_Next_Debug): Same fix
30143 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
30144 maintain back pointers now, though we did not used to, and comments
30146 (Prepend): Remove pragma Inline.
30147 (Remove_Next): Same cleanup
30149 2004-12-07 Thomas Quinot <quinot@adacore.com>
30151 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
30152 used to record an implicit dereference as a read operation on its
30153 prefix when operating under -gnatc. Necessary to avoid spurious
30154 'variable assigned but never read' warnings in that mode.
30155 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
30156 is a non-overloaded implicit dereference, call the above subprogram to
30157 ensure proper recording of references.
30159 2004-12-07 Gary Dismukes <dismukes@adacore.com>
30161 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

30209 2004-12-07 Vincent Celier <celier@adacore.com>
30211 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
30212 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
30213 and -eit to -ept. Added qualifier
30214 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
30216 2004-11-27 Andreas Schwab <schwab@suse.de>
30218 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
30220 2004-11-25 Arnaud Charlet <charlet@adacore.com>
30222 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
30223 internal implementation unit GNAT.Sockets.Thin,
30224 as their usage for sockets is non-portable (using the read and write
30225 functions from the system runtime library is fine on UNIX but won't
30226 work under Windows).

30230 2004-11-25 Arnaud Charlet <charlet@adacore.com>

30279 (Setup_Exception): Do nothing in the GNAT SJLJ case.
30281 * gigi.h (others_decl, all_others_decl): New decls representing the
30282 new Others_Value and All_Others_Value objects.
30283 (struct attrib): Rename "arg" component as "args", since GCC expects a
30284 list of arguments in there.
30286 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
30287 corresponding objects exported by a-exexpr, instead of hardcoded dummy
30290 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
30291 others_decl and all_others_decl instead of hardcoded dummy addresses
30292 to represent "others" and "all others" choices, which is cleaner and
30293 more flexible with respect to the possible eh pointer encoding policies.
30295 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
30296 (process_attributes): Account for the naming change of the "args"
30297 attribute list entry component.
30299 * decl.c (build_attr_list): Rename into prepend_attributes to allow
30300 cumulating attributes for different entities into a single list.
30301 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
30302 attributes for the current entity and propagate first subtype
30303 attributes to other subtypes.
30304 <E_Procedure>: Attribute arguments are attr->args and not
30305 attr->arg any more.
30306 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
30307 argument provided, as this is what GCC expects. Use NULL_TREE instead
30310 2004-11-18 Robert Dewar <dewar@adacore.com>
30312 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

30324 procedures factors the common processing for building an RPC receiver
30325 for an RCI package or an RACW type.

30330 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
30332 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
30334 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
30335 distribution subprogram identifiers that are either subprogram numbers
30337 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
30338 string distribution identifiers assigned to a given subprogram.
30339 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
30340 (Add_RAS_Dereference_TSS): Add comments.
30341 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
30342 is not referenced yet because it will be used by the PolyORB DSA
30344 (Insert_Partition_Check): Remove fossile code.
30345 (First_RCI_Subprogram_Id): Document this constant.
30346 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
30348 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
30349 replaced with calls to Get_Library_Unit_Name_String. Previously there
30350 were several instances of the same code in different locations in the
30351 compiler; this checkin completes the replacement of all of these
30352 instances with calls to a common subprogram.
30353 Minor reformatting.
30355 * sem_dist.adb: Remove comment noting that RPC receiver generation
30356 should be disabled for RACWs that implement RASs.
30357 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
30359 * sem_util.ads, sem_util.adb (Has_Stream): New function

30361 qualified name of a library unit into the name buffer.
30362 (Note_Possible_Modification): Generate a reference only
30363 if the context comes from source.
30365 * snames.ads (PCS_Names): New subtype corresponding to names of
30366 supported implementations of the Partition Communication Subsystem
30367 (PCS) (i.e. the runtime library support modules for the distributed

30371 Ed Schonberg <schonberg@adacore.com>
30373 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
30374 (Has_Rep_Pragma): New function
30375 (Has_Attribute_Definition_Clause): New function
30376 (Record_Rep_Pragma): Moved here from sem_ch13.adb
30377 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
30379 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
30381 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
30382 (Expand_Pragma_Psect_Object): New procedure
30383 These procedures contain the revised and cleaned up processing for
30384 these two pragmas. This processing was formerly in Sem_Prag, but
30385 is more appropriately moved here. The cleanup involves making sure
30386 that the pragmas are properly attached to the tree, and that no
30387 nodes are improperly shared.
30389 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
30390 pragmas to Exp_Prag, which is more appropriate.
30391 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
30392 check for duplicates Remove use of Is_Psected flag, no longer needed.
30393 Use new Make_String_Literal function with string.
30395 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
30396 that are functions return universal values, that have to be converted
30397 to the context type.
30398 Use new Make_String_Literal function with string.
30399 (Get_Stream_Convert_Pragma): New function, replaces the use of
30400 Get_Rep_Pragma, which had to be kludged to work in this case.
30402 * freeze.adb: Use new Has_Rep_Pragma function
30404 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
30405 function with string.
30406 Use new Has_Rep_Pragma function.
30408 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
30411 2004-11-18 Robert Dewar <dewar@adacore.com>
30413 * errout.ads, errout.adb: (First_Sloc): New function
30415 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
30416 check (-gnatyx) instead of being included as a redundant construct
30419 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
30420 Style_Check_Order_Subprograms.
30422 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
30423 stylesw.adb: Add Style_Check_Xtra_Parens
30425 * usage.adb: Add line for -gnatyx (check extra parens)
30427 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
30429 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30430 Robert Dewar <dewar@adacore.com>
30432 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
30433 discriminant of a constrained subtype, analyze the copy of the
30434 corresponding constraint, because in some cases it may be only
30435 partially analyzed.
30436 Removes long-lived ??? comments.
30438 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
30439 handled controlled or secondary-stack expressions within the
30440 iteration_scheme of a loop.
30442 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
30443 bounds that may contain functions calls, to prevent memory leaks when
30444 the bound contains a call to a function that uses the secondary stack.
30445 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
30446 generate temporaries for loop bounds that might contain function calls
30447 that require secondary stack and/or finalization actions.
30449 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
30450 selected component and the selector is overloadable (not just a
30451 function) treat as function call, Analyze_Call will disambiguate if
30453 (Analyze_Selected_Component): Do not generate an actual subtype for the
30454 selected component if expansion is disabled. The actual subtype is only
30455 needed for constraint checks.
30456 (Analyze_Allocator): If restriction No_Streams is set, then do
30457 not permit objects to be declared of a stream type, or of a
30458 composite type containing a stream.
30460 * restrict.ads: Remove the a-stream entry from Unit_Array, since
30461 No_Streams no longer prohibits with'ing this package.
30463 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
30464 discriminants, but the parent base has unknown discriminants, there is
30465 no discriminant constraint to inherit. Such a discrepancy can arise
30466 when the actual for a formal type with unknown discriminants is a
30467 similar private type whose full view has discriminants.
30468 (Analyze_Object_Declaration): If restriction No_Streams is set, then
30469 do not permit objects to be declared of a stream type, or of a
30470 composite type containing a stream.
30472 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30474 * exp_dbug.ads: Update documentation to reflect simpler encoding for
30475 protected operations.
30477 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
30478 generated name, it complicates decoding in gdb and hinders debugging
30479 of protected operations.
30480 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
30481 flag for the protected entry barrier function.
30482 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
30483 flag for the protected entry function.
30485 2004-11-18 Nicolas Setton <setton@adacore.com>
30487 * expect.c: Define __unix__ when __APPLE__ is defined.
30489 * Makefile.in: Inform the value of the variable GMEM_LIB in the
30490 Darwin-specific section.
30492 * lang-specs.h: Change the placement of the %1 marker.
30493 Works around the fact that gcc adds -fPIC by default under Darwin.
30495 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30497 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
30498 type of the object with the packed array type, set the Analyzed flag
30499 on the object if it is an entity or simple indexed component, to avoid
30500 spurious type errors.
30502 2004-11-18 Gary Dismukes <dismukes@adacore.com>
30504 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
30505 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
30506 separate line from the version message.
30508 2004-11-18 Ed Falis <falis@adacore.com>
30510 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
30512 (init_float): Eliminate initialization of floating point status for
30513 AE653. The instructions have no effect for vThreads.
30515 2004-11-18 Vincent Celier <celier@adacore.com>
30517 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
30518 gnatbind is invoked with -shared.
30520 2004-11-18 Jose Ruiz <ruiz@adacore.com>
30522 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
30523 for Detect_Blocking which is redundant with the check done within the
30524 procedure Protected_Single_Entry_Call.
30525 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
30526 Detect_Blocking which is redundant with the check done within the
30527 procedure Protected_Single_Entry_Call.
30529 2004-11-18 Vincent Celier <celier@adacore.com>
30531 * makegpr.adb (Compile): Put the compiling switches (in package
30532 Compiler and on the command line) immediately after "-c", instead of
30533 at the end of the command line invocation of the compiler, when
30534 compiling a non-Ada file.
30535 (Build_Global_Archive): When there is no need to rebuild the archive,
30536 set Global_Archive_Exists, so that the archive is passed to the linker
30539 2004-11-18 Robert Dewar <dewar@adacore.com>
30540 Sergey Rybin <rybin@adacore.com>
30543 Remove extra paren check from list of checks for redundant constructs
30544 Add documentation of new -gnatyx style check (check extra parens)
30545 Remove paragraph about gnatelim debug options.
30547 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
30548 objects rather than forbidding dependencies on the package Ada.Streams.
30550 * sinfo.ads: Add ??? note that we should document pragmas passed to
30553 * g-expect.ads: Fix a few typos in the comments.
30555 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
30557 * misc.c (gnat_handle_option): Use %< and %> for quoting in
30560 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
30562 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
30564 2004-11-07 Andreas Schwab <schwab@suse.de>
30566 * Makefile.in (install-gnatlib): Remove spurious hyphen.
30568 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
30571 * Makefile.in (darwin): Set soext to .dylib.
30573 2004-10-26 Vincent Celier <celier@gnat.com>
30574 Thomas Quinot <quinot@act-europe.fr>
30576 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
30577 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
30578 there is no use of GNAT.Sockets.Constants.
30579 Remove remaining pragma Import for C_Write
30580 Remove C_Read and C_Write from internal implementation unit
30581 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30582 the read and write functions from the system runtime library is fine
30583 on UNIX but won't work under Windows).
30585 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30586 (Check_Selector): Use C_Recv instead of C_Read.
30587 Selectors are the GNAT.Sockets abstraction to perform a select()
30588 call on a set of descriptors. To allow abortion of an ongoing
30589 select operation, some data is written to a dedicated socket that
30590 is always monitored.
30591 Under Windows, the write and read library functions cannot operate
30592 on sockets, so we need to use send and recv instead, which is portable
30593 across all supported platforms.
30595 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
30596 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
30597 (using the read and write functions from the system runtime library is
30598 fine on UNIX but won't work under Windows).
30600 2004-10-26 Nicolas Setton <setton@act-europe.fr>
30602 * mlib-tgt-darwin.adb: New file.
30604 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30605 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30606 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
30607 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
30610 * Makefile.in: Add support for building shared libraries under Darwin.
30611 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
30612 the low level EH init subprogram to be called from __gnat_initialize.
30614 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
30615 indicates which options to pass to the archive indexer.
30617 * mlib-utl.adb: Add support for calling ranlib with additional
30618 options. This is needed for instance under Mac OS X.
30619 (Ranlib_Options): New global variable, used to store the potential
30620 options to pass to ranlib.
30621 (Ar): Use Ranlib_Options when spawning ranlib.
30622 (Initialize): Set the value of ranlib option.
30624 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30626 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30627 instead of 8K, to reflect the real potential needs for stack-checking
30630 2004-10-26 Pascal Obry <obry@gnat.com>
30632 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30634 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30635 Windows only the initial thread stack size can be set so it is good to
30636 start we a low stack size.
30637 The OS will adjust the size as needed.
30639 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30640 Nicolas Setton <setton@act-europe.fr>
30642 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30643 "__unix__" instead of "unix".
30644 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30645 sections were just mistakenly ignored. The former is
30646 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30647 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30648 of hpux. This prevents an unwanted definition of the symbol
30649 convert_addresses in adaint.o.
30651 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30653 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30654 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30656 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30658 * a-filico.ads, a-filico.adb: fix incorrect header.
30660 2004-10-26 Javier Miranda <miranda@gnat.com>
30662 * a-ststio.ads: Fix typo in identifier
30664 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30666 * sem_ch4.adb: Minor reformatting.
30668 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30670 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30671 enabled, check the result of unary and binary operations when the
30672 expression is the right-hand side of an assignment.
30674 2004-10-26 Vincent Celier <celier@gnat.com>
30676 * clean.adb (Delete): Do not output warnings when in quiet output and
30677 not in verbose mode.
30678 (Force_Deletions): New Boolean flag, defaulted to False
30679 (Delete): Only delete a file if it is writable, and when
30680 Force_Deletions is True.
30681 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30682 (Usage): Line for new switch -f
30683 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30686 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30688 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30689 JM type only if its size matches that of the wrapper. When a size is
30690 prescribed and the field is not aliased, remove the wrapper of a JM
30691 type only if the size is not greater than that of the packed array.
30692 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30695 2004-10-26 Geert Bosch <bosch@gnat.com>
30697 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30698 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30699 (Pred): Implement in terms of Succ.
30701 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30703 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30704 unchecked conversion is safe for in-place use if the expression of the
30705 conversion is safe.
30706 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30707 be expandable in place even if the aggregate does not come from source.
30708 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30709 designated object of an allocator in place, rather than building it
30710 first on the stack. The previous scheme forces a full copy of the array,
30711 and may be altogether unsusable if the size of the array is too large
30712 for stack allocation.
30714 2004-10-26 Robert Dewar <dewar@gnat.com>
30716 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30717 compares if the component is atomic.
30719 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30720 array assignment if the component type is atomic.
30722 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30723 Eric Botcazou <ebotcazou@act-europe.fr>
30725 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30726 is aliased and is a by_reference type, do not pass by copy.
30727 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30728 detect whether the call is in the right side of an assignment or
30729 the expression of an object declaration. Recurse on component
30730 association within aggregates.
30731 Call it in the condition that determines whether the temporary is
30732 necessary for correct stack-checking.
30734 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30736 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30737 RACW_Type, used in the PolyORB version.
30738 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30739 version and the GARLIC version.
30741 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30742 Rename RCI_Info to RCI_Locator for better consistency between the
30743 GARLIC and PolyORB versions of the distributed systems annex.
30744 (DSA_Implementation_Name): This enumeration lists the possible
30745 implementations of the Partition Communication Subsystem for the
30746 Distributed Systems Annex (DSA). The three available implementations
30747 are the dummy stub implementation (No_DSA), and two versions based on
30748 two different distribution runtime libraries: GARLIC and PolyORB. Both
30749 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30751 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30754 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30755 between the GARLIC and PolyORB versions of the distributed systems
30757 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30759 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30761 * gnat1drv.adb: Suppress calling the back end when
30762 Frontend_Layout_On_Target is true.
30764 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30766 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30767 Set_Read_Only): New subprograms.
30768 These new routines allow the user to set or unset the Owner execute
30769 and Owner write permission flags on a file.
30771 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30772 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30774 2004-10-26 Matthew Gingell <gingell@gnat.com>
30776 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30778 2004-10-26 Pascal Obry <obry@gnat.com>
30780 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30781 memory before the faulting page we properly test the process read
30782 access for this address using appropriate Win32 routine.
30783 (HPUX sections): guard with "__hpux__" instead of "hpux".
30785 2004-10-26 Robert Dewar <dewar@gnat.com>
30787 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30788 entry parameter if pragma Unreferenced set, since we do not properly
30789 handle the case of multiple parameters.
30791 2004-10-26 Vincent Celier <celier@gnat.com>
30793 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30794 (Ada_Objects_Path.Add): For a library project, add to the object path
30795 the library directory only if there is no object directory or if the
30796 library directory contains ALI files.
30797 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30799 2004-10-26 Vincent Celier <celier@gnat.com>
30801 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30802 extension of library projects.
30804 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30805 path defaults to ".:<prefix>/lib/gnat".
30806 (Parse): For an extending all project, allow direct import of a project
30807 that is virtually extended.
30809 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30810 the specified name is directly imported, return its ID. Otherwise, if
30811 an extension of this project is imported, return the ID of the
30814 2004-10-26 Robert Dewar <dewar@gnat.com>
30816 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30817 (Sub3): New procedure, used by Scaled_Divide
30818 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30819 correct more than one instance of failure to propagate carries
30821 (Double_Divide): Handle overflow case of largest negative number
30822 divided by minus one.
30824 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30825 the case of a quotient value out of range.
30828 2004-10-26 Robert Dewar <dewar@gnat.com>
30830 * s-bitops.adb (Bit_Eq): Remove redundant check.
30832 * s-bitops.ads: Minor comment updates
30833 Change some occurrences of Address to System.Address
30835 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30837 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30839 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30840 accessibility check to prefix that is a protected operation.
30842 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30844 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30845 empty, post message on stub.
30847 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30848 Javier Miranda <miranda@gnat.com>
30850 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30851 current instance appears within a unit that is directly in the context
30853 Used to determine whether the body of the instance should be analyzed
30854 immediately after its spec, to make its subprogram bodies available
30855 for front-end inlining.
30856 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30857 constraint is not allowed on the component type (AARM 12.5.3(3))
30859 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30861 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30862 'Storage_Pool): enhance, document & limit detection of non-sharable
30865 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30867 * s-pooglo.ads: Add more documentation now that this pool is properly
30870 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30872 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30873 or protected type with discriminants, do not constrain the
30874 corresponding record type if the subtype declaration has no
30875 discriminant constraints. This can be the case in source code, or in
30876 the subtype declaration created to rename an actual type within an
30879 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30881 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30882 different kind of stub (possibly wrong name for file), do not check
30884 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30885 includes call to some function that returns an unconstrained type, do
30888 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30890 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30891 appear in the code for the main unit. Dependencies among units in the
30892 context of the main unit are established when those other units are
30893 compiled. Otherwise spurious elaboration constraints can generate
30894 incorrect elaboration circularities.
30896 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30897 Ed Schonberg <schonberg@gnat.com>
30899 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30900 subprogram is called with a parameter that is not an object name. This
30901 situation arises for some cases of illegal code, which is diagnosed
30902 later, and in this case it is wrong to call Is_Aliased, as that might
30903 cause a compiler crash.
30904 (Explain_Limited_Type): Refine previous fix to include
30905 inherited components of derived types, to provide complete information.
30907 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30908 is the prival for a protected object.
30909 It is necessary to mark this entity as a variable, in addition to
30910 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30911 modified to avoid checking the Aliased flag on entities that are not
30912 objects. (Checking that flag for non-objects is erroneous and could
30913 lead to a compiler crash).
30915 2004-10-26 Robert Dewar <dewar@gnat.com>
30917 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30918 X_Frac = 0.5, then we know that the number X must be positive.
30919 (Succ): Remove the same redundant test, and also fix the primary test
30920 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30922 (Decompose): Add fuller comments to spec
30924 2004-10-26 Pascal Obry <obry@gnat.com>
30926 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30927 validity (process must have read access). Set to 0 in all other cases.
30928 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30929 violation on Win32.
30930 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30931 segmentation violation.
30933 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30935 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30936 whose type is a constructed subtype of an aliased object with an
30937 unconstrained nominal subtype, convert the actual to the constructed
30938 subtype before taking its address.
30940 2004-10-26 Vincent Celier <celier@gnat.com>
30942 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30943 (Is_Path_Name_Case_Sensitive): New function
30945 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30946 (Base_Name, Simple_Name, Current_Directory, Compose,
30947 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30950 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30951 Vasiliy Fofanov <fofanov@act-europe.fr>
30952 Vincent Celier <celier@gnat.com>
30954 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30955 "memory management issues" section and document some of the useful
30956 memory pools provided as part of the GNAT library.
30957 Remove "virtual" from declaration of A::method2 in
30958 the simple example of Ada/C++ mixed system.
30959 Library Projects may be virtually extended: their virtual extensions
30960 are not Library Projects.
30961 Added section on extending project hierarchies.
30963 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30965 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30967 (__gnat_portable_spawn): Remove const.
30969 * mingw32.h (MAXPATHLEN): Check for previous definition.
30971 2004-10-17 Matthias Klose <doko@debian.org>
30973 * gnatvsn.ads: Set gnat library version to 4.0.
30975 2004-10-05 Vincent Celier <celier@gnat.com>
30977 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30979 2004-10-04 Laurent Guerby <laurent@guerby.net>
30982 * Makefile.in: Define and use RANLIB_FLAGS.
30984 2004-10-04 Pascal Obry <obry@gnat.com>
30986 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30987 other x86 platforms).
30989 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30991 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30992 in general and triggers stack alignment adjustment for thread entry
30993 points on targets where this is necessary.
30995 2004-10-04 Bernard Banner <banner@gnat.com>
30998 * Makefile.in: Add section for powerpc linux
30999 Add variant i-vxwork-x86.ads
31001 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
31003 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
31005 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
31006 table registration calls when need be. Ensures no reference to the crt
31007 ctors symbol are issued in the SJLJ case, which avoids possible
31008 undefined symbol errors in the case of modules to be statically linked
31011 2004-10-04 Javier Miranda <miranda@gnat.com>
31013 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
31014 in-line the code corresponding to subprogram Analyze_Actuals. In
31015 addition, analyze the actuals only in case of subprogram call.
31017 2004-10-04 Ed Falis <falis@gnat.com>
31019 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
31021 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
31023 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
31024 in the documentation.
31026 2004-10-04 Robert Dewar <dewar@gnat.com>
31028 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
31030 (Analyze_Block_Statement): Add circuitry to detect following dead code
31031 (Check_Unreachable_Code): Handle case of block exit
31033 2004-10-04 Robert Dewar <dewar@gnat.com>
31035 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
31036 (XMatchD): Avoid warning for Logic_Error call
31038 2004-10-04 Robert Dewar <dewar@gnat.com>
31040 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
31041 consider expressions buried within a procedure actual to be an actual.
31042 This caused some blowups with uses of packed slices within a procedure
31045 2004-10-04 Robert Dewar <dewar@gnat.com>
31047 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
31048 longer need to be initialized to zero.
31049 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
31050 initialized to zero.
31052 * checks.adb (Expr_Known_Valid): Packed arrays are now always
31053 considered valid, even if the representation is modular. That's correct
31054 now that we no longer initialize packed modular arrays to zero.
31056 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
31057 suffixes. These are now documented as the only cases in which the
31058 debugger ignores outer records.
31059 Previously, the spec allowed arbitrary suffixes for this purpose.
31060 Change name of LJM to JM for packed array pad records
31061 Create separate section on packed array handling, and add a whole new
31062 set of comments to this section describing the situation with packed
31063 modular types and justification requirements depending on endianness.
31065 2004-10-04 Robert Dewar <dewar@gnat.com>
31067 * a-except.adb: Add a comment for last change
31069 * einfo.ads: Minor spelling correction in comment
31071 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
31073 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
31076 * sem_util.ads: Minor comment update
31078 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31080 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
31081 Inline_Always when in Configurable_Run_Time mode.
31083 * sem_prag.adb (Process_Convention): If entity is an inherited
31084 subprogram, apply convention to parent subprogram if in same scope.
31085 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
31086 when in Configurable_Run_Time mode.
31088 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31090 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
31091 class_wide type after component list has been inherited.
31093 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31095 * sem_ch12.adb (Check_Generic_Actuals): New predicate
31096 Denotes_Previous_Actual, to handle properly the case of a private
31097 actual that is also the component type of a subsequent array actual.
31098 The visibility status of the first actual is not affected when the
31099 second is installed.
31100 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
31101 make fully recursive the treatment of formals of packages declared
31103 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
31104 the above on exit from an instantiation.
31105 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
31106 current instantiation which is now complete.
31107 (Analyze_Package_Instantiation): No instantiated body is needed if the
31108 main unit is generic. Efficient, and avoid anomalies when a instance
31109 appears in a package accessed through rtsfind.
31111 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31113 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
31114 do not generate a declaration for a temporary if the call is part of a
31115 library-level instantiation.
31117 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31119 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
31120 searching for a limited component to flag.
31122 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
31123 expansion of Input, to account for the fact that the implicit call
31124 generated by the attribute reference must freeze the user-defined
31125 stream subprogram. This is only relevant to 'Input, because it can
31126 appear in an object declaration, prior to the body of the subprogram.
31128 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
31129 expansion can proceed and further errors uncovered.
31130 (Minor clean up): Fix cases of using | instead of \ for continuation
31133 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
31135 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
31137 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
31138 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
31139 Use gcc_assert and gcc_unreachable.
31141 * decl.c (gnat_to_gnu_entity, case object): Check and process a
31142 specified alignment before validating size.
31143 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
31144 stripped-down declaration for the type of the inner field when making
31147 * utils.c (finish_record_type): Do not compute the size in units
31148 incrementally. Instead compute it once for the rep clause case.
31149 Use gcc_assert and gcc_unreachable.
31151 2004-10-04 Vincent Celier <celier@gnat.com>
31153 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
31155 (Is_Valid_Path_Name): Take '/' as a directory separator.
31157 2004-10-04 Vincent Celier <celier@gnat.com>
31159 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
31160 (Extended_Project) only if Extended_Project is defined, to avoid
31162 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
31164 (Parse_Single_Project): Ditto.
31166 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
31167 Add_To_Project_Path for virtual projects.
31169 2004-10-04 Vincent Celier <celier@gnat.com>
31171 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
31172 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
31173 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
31174 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
31175 parameter Options_2.
31177 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
31178 Build_Dynamic_Library with an empty Options_2.
31180 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
31183 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
31184 directory separator, if any.
31185 (Gprmake): Do not allow mains on the command line for library projects.
31186 Do not attempt to link when the project is a library project.
31187 (Library_Opts): New table to store Library_Options.
31188 (Build_Library): If Library_Options is specified, pass these options
31189 when building a shared library.
31191 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
31193 * s-tposen.adb (Service_Entry): The object must be always unlocked at
31194 the end of this procedure now that the unlock operation was inserted
31197 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
31199 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
31200 corresponding to the Preallocated_Stacks flags in System.
31201 (Get_Target_Parameters): Including the processing for
31202 Preallocated_Stacks.
31204 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
31205 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

31212 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
31213 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
31214 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
31215 used to signal whether the compiler creates the required stacks and
31216 descriptors for the different tasks (when True) or it is done by the
31217 underlying operating system at run time (when False).
31218 It is initially set to False in all targets.
31220 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
31221 if it is supported by the target.
31222 (Make_Task_Create_Call): Pass the stack address if it has been
31223 previously created. Otherwise pass a Null_Address.
31225 * snames.adb: Add _stack.
31227 * snames.ads: Add Name_uStack. Required to allow the expander to
31228 statically allocated task stacks.
31230 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
31231 Stack_Address argument.
31232 Check that its value is equal to Null_Address because this target does
31233 not support the static stack allocation.
31235 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
31237 * usage.adb: Change "pragma inline" to "pragma Inline" in information
31240 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
31242 * exp_dist.adb: Split declaration of asynchronous flag out of
31243 Add_RACW_Read_Attribute.
31244 Minor reformatting for better alignment with PolyORB version.
31245 Store the entity for the asynchronous flag of an RACW, rather than the
31246 expression, in the asynchronous flags table. This will allow this flag
31247 to be used in other subprograms beside Add_RACW_Read_Attribute.
31249 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
31251 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
31252 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
31253 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
31254 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
31255 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
31256 sockets constant MSG_NOSIGNAL (Linux-specific).
31257 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
31258 all Send operations.
31259 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
31260 from trigerring SIGPIPE.
31261 Rename components to avoid clash with Ada 2005 possible reserved
31263 (Check_Selector): When the select system call returns with an error
31264 condition, propagate Socket_Error to the caller.
31266 2004-10-01 Jan Hubicka <jh@suse.cz>
31268 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
31270 2004-09-23 Robert Dewar <dewar@gnat.com>
31273 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
31274 instead do this at freeze time (we won't do it if there is an address
31276 Change "pragma inline" to "pragma Inline" in information and error
31278 Minor reformatting.
31280 * freeze.adb (Check_Address_Clause): Remove previous change, not the
31281 right way of doing things after all.
31282 (Freeze_Entity): For object, set Is_Public for imported entities
31283 unless there is an address clause present.
31285 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
31287 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
31288 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
31289 ensures proper handling of types with rep clauses, which might have
31290 their TYPE_SIZE set already.
31292 2004-09-21 Robert Dewar <dewar@gnat.com>
31294 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
31295 packed array types in both little- and big-endian cases. This change
31296 ensures that we no longer count on the unused bits being initialized
31297 for such types (and in particular ensures that equality testing will
31298 only read the relevant bits).
31299 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
31300 These changes mean that we no longer need to initialize small packed
31302 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
31303 optimization to an LJM field as to its parent field.
31305 * ada-tree.h, trans.c, utils.c, utils2.c:
31306 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
31308 2004-09-20 Jan Hubicka <jh@suse.cz>
31310 * utils.c (gnat_finalize): Remove.
31311 (end_subprog_body): Directly call cgraph_finalize_function;
31312 do not lower the nested functions.
31314 2004-09-20 Robert Dewar <dewar@gnat.com>
31317 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public

31430 raise Program_Error if called from a protected operation.
31432 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
31433 the protected action nesting level.
31434 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
31435 protected action nesting level.
31436 (Unlock): When pragma Detect_Blocking is active decrease the protected
31437 action nesting level.
31439 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
31440 Protected_Action_Nesting.
31442 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
31443 Common_ATCB record. It contains the dynamic level of protected action
31444 nesting for each task. It is needed for checking whether potentially
31445 blocking operations are called from protected operations.
31446 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
31447 Detect_Blocking is active or not in the partition.
31449 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

31483 contains the required machinery for handling that.
31485 * sem_util.ads: Change comment associated to procedure
31486 Check_Potentially_Blocking_Operation.
31487 This procedure does not insert a call for raising the exception because
31488 that is currently done by the run time.
31490 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
31492 * init.c: Add the global variable __gl_detect_blocking that indicates
31493 whether pragma Detect_Blocking is active (1) or not (0). Needed for
31494 making the pragma available at run time.
31495 (__gnat_set_globals): Pass and update the detect_blocking parameter.

31502 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
31503 DB is found in the ali file. Any unit compiled with pragma
31504 Detect_Blocking active forces its effect in the whole partition.
31506 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
31507 Detect_Blocking is active and delay is called from a protected
31510 * bindgen.adb (Gen_Adainit_Ada): When generating the call to

31524 (Register_Receiving_Stub): Add Subp_Info formal parameter.
31525 Update API in placeholder implemetation of s-parint to reflect changes
31526 in distribution runtime library.
31528 * sem_ch3.adb (Expand_Derived_Record): Rename to
31529 Expand_Record_Extension.
31531 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
31532 primitive operations of potentially distributed object types that have
31533 non-controlling anonymous access formals.
31535 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
31537 New implementation of expansion for remote access-to-subprogram types,
31538 based on the RACW infrastructure.
31539 This version of sem_dist is compatible with PolyORB/DSA as well as
31542 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
31543 Asynchrronous that applies to a remote access-to-subprogram type, mark
31544 the underlying RACW type as asynchronous.
31546 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
31547 __gnat_using_gnu_linker to 1.

31556 * exp_ch3.adb (Expand_Derived_Record): Rename to
31557 Expand_Record_Extension.
31558 (Build_Record_Init_Proc.Build_Assignment): The default expression in
31559 a component declaration must remain attached at that point in the
31560 tree so New_Copy_Tree copies it if the enclosing record type is derived.
31561 It is therefore necessary to take a copy of the expression when building
31562 the corresponding assignment statement in the init proc.
31563 As a side effect, in the case of a derived record type, we now see the
31564 original expression, without any rewriting that could have occurred
31565 during expansion of the ancestor type's init proc, and we do not need
31566 to go back to Original_Node.
31568 * exp_ch3.ads (Expand_Derived_Record): Rename to
31569 Expand_Record_Extension.
31571 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

31574 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
31575 New subprograms. Used to create a proxy tagged object for a remote
31576 subprogram. The proxy object is used as the designated object
31577 for RAS values on the same partition (unless All_Calls_Remote applies).
31578 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
31579 System.Partition_Interface.Get_Unique_Remote_Pointer.

31584 New implementation of expansion for remote access-to-subprogram types,
31585 based on the RACW infrastructure.
31587 * exp_dist.ads (Copy_Specification): Update comment to note that this
31588 function can copy the specification from either a subprogram
31589 specification or an access-to-subprogram type definition.
31591 2004-09-09 Ed Schonberg <schonberg@gnat.com>
31593 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
31594 in an instance, between an explicit subprogram an one inherited from a
31595 type derived from an actual.
31597 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
31598 add a polling call if the subprogram is to be inlined by the back-end,
31599 to avoid repeated calls with multiple inlinings.
31601 * checks.adb (Apply_Alignment_Check): If the expression in the address
31602 clause is a call whose name is not a static entity (e.g. a dispatching
31603 call), treat as dynamic.

31607 * g-trasym.ads: Minor reformatting
31609 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

31621 enable map file generation. Add the right option to generate the map
31622 file if Map_File is set to True.
31624 * gnatdll.adb (Gen_Map_File): New variable.
31625 (Syntax): Add info about new -m (Map_File) option.

31653 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31654 of variable length temporaries for function return now that the
31655 back-end and gigi support it.

31732 consistent treatment of entity references contained within the
31733 enclosed procedure call.
31735 2004-09-01 Vincent Celier <celier@gnat.com>
31737 * bindgen.adb: (Set_EA_Last): New procedure

31849 for a global aliased object with a variable size and an unconstrained
31850 nominal subtype, pretend there is no initializer if the one we have is
31851 incomplete, and avoid referencing an inexistant component in there. The
31852 part we have will be rebuilt anyway and the reference may confuse

31876 unit, this is an attempt to inline a construct that is not available in
31877 the current restricted mode, so abort rather than trying to continue.
31879 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
31880 discriminants that rename those of the parent, recover names of
31881 original discriminants for the constraint on the full view of the

31911 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
31912 returning C.int, to avoid using a derived boolean type.
31914 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
31915 Duplicate_Subexpr_No_Checks in preference to direct use of
31916 Remove_Side_Effects and New_Copy_Tree.

31943 ignore overflows on low and high bounds of an index to also account for
31944 differences in signedness between sizetype and gnu_index_subtype.
31945 These are as legitimate as the ones caused by a lower TYPE_PRECISION

34266 2004-05-14 Robert Dewar <dewar@gnat.com>
34268 * gnat_ugn.texi: Minor change to -gnatS documentation
34270 * sprint.adb: Remove some instances of Assert (False) and for this
34271 purpose replace them by output of a ??? string.
34273 * checks.adb, exp_aggr.adb, sem_elim.adb: Remove useless pragma
34276 * lib-writ.adb, lib-load.adb, lib.ads, lib.adb: Remove Dependent_Unit
34277 flag processing. This was suppressing required dependencies in
34278 No_Run_Time mode and is not needed since the binder does not generate
34279 references for things in libgnat anyway.
34281 * sem_ch3.adb (Access_Type_Declaration): Reorganize code to avoid GCC
34284 2004-05-14 Thomas Quinot <quinot@act-europe.fr>
34286 * gnat_ugn.texi: Document AIX-specific issue with initialization of
34289 * exp_ch4.adb (Insert_Dereference_Action): Do not generate dereference
34290 action for the case of an actual parameter in an init proc call.
34292 2004-05-14 Ed Schonberg <schonberg@gnat.com>
34294 * sem_ch4.adb (Analyze_Selected_Component): If prefix is a protected
34295 subtype, check visible entities in base type.
34297 * exp_ch7.adb (Clean_Simple_Protected_Objects): Do not generate cleanup
34298 actions if the object is a renaming.
34300 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
34301 Check_Formal_Package_Instance, to determine more precisely when the
34302 formal and the actual denote the same entity.
34304 2004-05-14 Javier Miranda <miranda@gnat.com>
34306 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
34308 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
34309 corresponding to a private_with must be removed from visibility; it
34310 will be made visible later, just before we analyze the private part of
34312 (Check_Private_Child_Unit): Allow private_with clauses in public
34314 (Install_Siblings): Make visible the private entities of private-withed
34316 (Install_Withed_Unit): Do not install the private withed unit if we
34317 are compiling a package declaration and the Private_With_OK flag was
34318 not set by the caller. These declarations will be installed later,
34319 just before we analyze the private part of the package.
34321 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
34322 during the evaluation of the expression that initializes the object,
34323 decorate it with the expected type to avoid cascade errors.
34326 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
34327 subprogram we have to install the private_with clauses after its
34328 specification has been analyzed (as documented in AI-262.TXT).
34330 * sem_ch8.adb (Has_Private_With): New function. Determines if the
34331 current compilation unit has a private with on a given entity.
34332 (Find_Direct_Name): Detect the Beaujolais problem described in
34335 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
34336 provides the functionality of the function Is_Ancestor that was
34337 previously available in sem_ch10. It has been renamed to avoid
34340 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
34342 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
34344 * utils.c (build_vms_descriptor): Use SImode pointers.
34346 2004-05-14 Vasiliy Fofanov <fofanov@act-europe.fr>
34348 * gnat_ugn.texi: Revised chapter "GNAT and Libraries".
34350 2004-05-14 GNAT Script <nobody@gnat.com>
34352 * Make-lang.in: Makefile automatically updated
34354 2004-05-14 Arnaud Charlet <charlet@act-europe.fr>
34356 Renaming of target specific files for clarity
34358 * Makefile.in: Rename GNAT target specific files.

34500 * trans.c (gnat_stabilize_reference_1): Remove case 'b'.
34502 2004-05-13 Diego Novillo <dnovillo@redhat.com>
34504 Merge from tree-ssa-20020619-branch.
34506 * config-lang.in (boot_language, build_by_default): Set
34508 * utils.c (unchecked_convert): Use OEP_ONLY_CONST.
34509 (max_size): Add static chain op for call_expr.
34511 2004-05-12 Richard Sandiford <rsandifo@redhat.com>
34514 * 5gmastop.adb (Roff): Choose between '4' and '0', not '4' and ' '.
34516 2004-05-11 Roger Sayle <roger@eyesopen.com>
34518 * utils.c (max_size): Use MIN_EXPR to find the minimum value of a
34521 2004-05-10 Doug Rupp <rupp@gnat.com>
34523 * 5qsystem.ads: Remove Short_Address subtype declaration. Moved to
34526 * s-auxdec.ads: Add Short_Address subtype (moved here from System).
34528 * Makefile.in: [VMS]: Add translation for 5qauxdec.ads.
34530 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
34531 Fixes undefined symbols in IA64 gnatlib.
34533 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
34535 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
34536 Short_Address). This will be moved to system.auxdec.
34538 2004-05-10 Thomas Quinot <quinot@act-europe.fr>
34540 * sem_util.adb: Replace test for presence of a node that is always
34541 present with a call to Discard_Node.
34543 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
34544 Analyze on the library unit node after generation of distribution stub
34545 constructs. The call was a no-op because Unit_Node has already been
34546 Analyzed, and the tree fragments for the distribution stubs are
34547 analyzed as they are inserted in Exp_Dist.
34548 Update comment regarding to distribution stubs to reflect that we
34549 do not generate stub in separate files anymore.
34551 * einfo.ads: Clarify the fact that a tagged private type has the
34552 E_Record_Type_With_Private Ekind.
34554 * erroutc.adb: Minor reformatting
34556 * erroutc.ads (Max_Msg_Length): Increase to cover possible larger
34557 values if line length is increased using -gnatyM (noticed during code
34560 * eval_fat.adb: Minor reformatting
34561 Put spaces around exponentiation operator
34563 2004-05-10 Ed Schonberg <schonberg@gnat.com>
34566 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): If prefix
34567 has been rewritten as an explicit dereference, retrieve type of
34568 original node to check for possibly unconstrained record type.
34570 2004-05-10 Ed Schonberg <schonberg@gnat.com>
34572 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
34573 overriding, use the operation of the parent unconditionally.
34575 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
34576 operation when either operand is a literal, to avoid further
34579 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
34580 overridden by a previous explicit declaration, mark the previous entity
34583 * sem_disp.adb (Check_Dispatching_Operation): New predicate
34584 Is_Visibly_Controlled, to determine whether a declaration of a
34585 primitive control operation for a derived type overrides an inherited
34586 one. Add warning if the explicit declaration does not override.
34588 2004-05-10 Vincent Celier <celier@gnat.com>
34590 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
34591 some cases when the sources are no longer present.
34593 * make.adb (Collect_Arguments): Fail if an external source, not part
34594 of any project need to be compiled, when switch -x has not been
34597 * makeusg.adb: Document new switch -x
34599 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
34600 defaulted to False.
34602 * switch-m.adb (Scan_Make_Switches): New switch -x
34604 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
34605 gnatmake switch -x.
34607 * gnat_ugn.texi: Document new gnatmake switch -x
34609 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
34611 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
34613 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
34614 (process_attributes): Likewise.
34616 2004-05-10 Joel Brobecker <brobecker@gnat.com>
34618 * s-inmaop.ads: Fix spelling mistake in one of the comments.
34620 2004-05-10 Robert Dewar <dewar@gnat.com>

35125 whether a pragma All_Calls_Remote applies to the subprogram on which
35127 No functional change is introduced by this revision; the new parameter

35717 * sem_prag.adb (Set_Exported): Warn about making static as result of
35718 export only when the export is coming from source. This may be not
35719 be true e.g. on VMS where we expand export pragmas for exception codes
35720 together with imported or exported exceptions, and we don't want the
35721 user to be warned about something he didn't write.
35723 2004-04-08 Thomas Quinot <quinot@act-europe.fr>
35725 * sem_util.adb (Note_Possible_Modification): Reorganize to remove code
35726 duplication between normal entities and those declared as renamings.

35826 specified radix_digits is greater or equal to machine_mantissa.
35828 2004-04-05 Javier Miranda <miranda@gnat.com>
35830 * par-ch3.adb: Complete documentation of previous change
35831 Correct wrong syntax documentation of the OBJECT_DECLARATION rule

35844 as is done for non-private derived record types.
35846 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
35847 Ada 2005 AI-310: an abstract non-dispatching operation is not a

35856 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
35857 statement whose right-hand side is an inlined call, save a copy of the
35858 original assignment subtree to preserve enough consistency for
35859 Analyze_Assignment to proceed.
35861 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
35862 complete assignment subtree which is now unnecessary, as the expansion
35863 of inlined call has been improved to preserve a consistent assignment
35864 tree. Note_Possible_Modification must be called only
35865 after checks have been applied, or else unnecessary checks will
35868 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35869 of explicit dereferences that do not Come_From_Source:
35870 - be selective on cases where we must go back to the dereferenced
35871 pointer (an assignment to an implicit dereference must not be
35872 recorded as modifying the pointer);
35873 - do not rely on Original_Node being present (Analyze_Assignment
35874 calls Note_Possible_Modification on a copied tree).
35876 * sem_warn.adb (Check_References): When an unset reference to a pointer
35877 that is never assigned is encountered, prefer '<pointer> may be null'

35947 a string literal, create a temporary for it, constant folding only
35948 handles scalars here.
35950 2004-04-01 Vincent Celier <celier@gnat.com>

36131 allows to configure paths for an executable name (gnatmake) different
36132 from the current one (gnatdist).
36134 2004-03-29 Ed Schonberg <schonberg@gnat.com>
36136 * exp_ch6.adb (Expand_Call): A call to a function declared in the
36137 current unit cannot be inlined if it appears in the body of a withed
36138 unit, to avoid order of elaboration problems in gigi.
36140 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
36141 information for protected (wrapper) operation as well, to simplify gdb
36144 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
36145 protected body, indicate that the entity for the generated spec comes

36187 a classwide type (for which Is_Object_Reference holds), but it can
36188 also be a value conversion for an access-to-classwide type. In the
36189 latter case, there is an implicit dereference, and the original node
36190 for the prefix does not verify Is_Object_Reference.
36192 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view

36218 value expressions to ensure that calls within a component definition
36219 will be checked (since those are evaluated during the record type's
36222 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>

36266 case when the source contains only comments.
36268 2004-03-22 Ed Schonberg <schonberg@gnat.com>
36270 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
36271 declaration for a child subprogram body that acts as a spec, indicate
36272 that the entity in the declaration needs debugging information.
36274 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
36275 full view if the subtype is created for a constrained record component;
36276 gigi has enough information to construct the record, and there is no
36277 place in the tree for the declaration.
36279 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
36280 serial number for the dummy body that is built for analysis, to avoid
36281 inconsistencies in the generation of internal names when compiling
36284 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
36286 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
36289 2004-03-22 GNAT Script <nobody@gnat.com>

36318 Minor reformatting.
36320 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
36322 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
36323 as regular exception objects and not as mere integers representing the
36324 condition code. The latter approach required some dynamics to mask off
36325 severity bits, which did not fit well into the GCC table based model.
36326 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
36327 exception data objects. We don't it and it would conflict with the other
36328 external symbol we have to generate for such exceptions.
36330 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
36331 the special code for VMS exceptions, since these are now represented
36332 as regular exceptions objects.
36334 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
36336 * decl.c (debug_no_type_hash): Remove.

36340 2004-03-19 Laurent Guerby <laurent@guerby.net>
36342 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
36343 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
36345 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
36347 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.

36349 (TYPE_RM_SIZE_INT): Directly use type.values.
36350 (TREE_LOOP_ID): Clean up check.
36351 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
36352 TYPE_VALUES, not TYPE_FIELDS.

36365 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
36367 * adaint.c: Update comments.
36369 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
36370 GNATLIB_SHARED for FreeBSD.
36372 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
36374 * init.c [VxWorks]: Do not fix the stack size for the environment task.
36375 When needed (stack checking) the stack size is retrieved
36376 from the VxWorks kernel.
36378 * Makefile.in: Flag -nostdinc is required when building the run time
36379 for avoiding looking for files in the base compiler.
36380 Add the VxWorks specific version of the package body for
36381 System.Stack_checking.Operations (5zstchop.adb).
36383 * Make-lang.in: Add the object file for
36384 System.Stack_Checking.Operations.
36386 * Makefile.rtl: Add object file for the package
36387 System.Stack_Checking.Operations.
36389 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
36391 * s-stache.ads, s-stache.adb: Move the operations related to stack
36392 checking from this package to package System.Stack_Checking.Operations.
36393 This way, stack checking operations are only linked in the final
36394 executable when using the -fstack-check flag.
36396 2004-03-18 Doug Rupp <rupp@gnat.com>
36398 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

36408 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
36409 the procedures Add_To_Path_File.
36410 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
36411 making sure that each directory is present only once and, for object
36412 dirs, when a directory already present is added, the duplicate is
36413 removed and the directory is always put as the last in the table.
36414 Write the path files at the end of these accumulations.
36416 * prj-nmsc.adb (Record_Source): Add source file name in hash table
36417 Files_Htable for all sources.
36419 * prj-proc.adb (Process): Remove restrictions between not directly
36420 related extending projects.

36428 parameter Trusted_Mode.
36430 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
36432 * scn.adb (Determine_License): Take into account a degenerated case
36433 when the source contains only comments.
36435 2004-03-18 Ed Schonberg <schonberg@gnat.com>
36437 * sem_warn.adb (Check_References): For a warning on a selected
36438 component that does not come from source, locate an uninitialized
36439 component of the record type to produce a more precise error message.
36441 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
36443 * 3zsoccon.ads: Fix multicast options.
36445 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
36448 2004-03-15 Robert Dewar <dewar@gnat.com>
36450 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
36451 pragma used for a private type.
36453 * lib-xref.adb (Generate_Reference): Do not generate warning if
36454 reference is in a different unit from the pragma Unreferenced.
36456 * 5vtpopde.adb: Minor reformatting
36457 Fix casing of To_Task_ID
36459 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
36460 flag if we have an unchecked conversion to an access type in the same
36463 2004-03-15 Geert Bosch <bosch@gnat.com>
36465 * a-ngcoty.adb (Modulus): In alternate formula for large real or
36466 imaginary parts, use Double precision throughout.
36468 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
36469 we want to be able to compile run-time with -gnata for testing, but
36470 this may also be instantiated in user code that is compiled with -gnata.
36472 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
36474 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
36475 codes. Having a separate type for this is useful to enforce consistency
36476 throughout the various run-time units.
36477 (Exception_Data): Use Exception_Code for Import_Code.
36479 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
36480 Natural and Integer in various places.

36482 with the severity bits masked off.
36483 (Register_VMS_Exception): Handle the additional exception data pointer

36487 component, now reflected by an exported accessor.
36488 (is_handled_by): New routine to compute whether the propagated
36489 occurrence matches some handler choice specification. Extracted out of
36490 get_action_description_for, and expanded to take care of the VMS
36492 (get_action_description_for): Use is_handled_by instead of an explicit
36493 complex condition to decide if the current choice at hand catches the
36494 propagated occurrence.
36496 * raise.h (Exception_Code): New type for C.
36498 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
36499 System.Standard_Library.Exception_Code, to allow references from the
36500 pragma import/export expander.
36502 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
36503 New accessors to allow easy access to GNAT exception data
36505 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
36506 redundant Handled_By_Others component, helper for the personality
36507 routine which will now be able to call the appropriate exception data
36510 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
36511 component of Standard_Exception_Type to be the closest possible to
36512 Exception_Code in System.Standard_Library, that we cannot get at this
36513 point. Expand a ??? comment to notify that this type node should
36514 probably be rewritten later on.
36516 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
36517 registration call to include a pointer to the exception object in the
36520 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
36521 instead of int and explicit bitmasks.
36523 2004-03-15 Vincent Celier <celier@gnat.com>
36525 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
36526 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
36528 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
36529 longer needed now that it is in the spec of
36530 System.Tasking.Task_Attributes.
36532 * adaint.h, adaint.c: (__gnat_create_output_file): New function
36534 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
36536 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
36538 * make.adb (Gnatmake): Do not check the executable suffix; it is being
36539 taken care of in Scan_Make_Arg.
36540 (Scan_Make_Arg): Add the executable suffix only if the argument
36541 following -o, in canonical case, does not end with the executable
36542 suffix. When in verbose mode and executable file name does not end
36543 with executable suffix, output the executable name, in canonical case.
36545 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
36546 to avoid warnings when instantiating Ada.Task_Attributes.
36549 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
36550 in the correct order.
36552 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

36557 directory, instead of the Value.
36558 (Find_Source_Dirs): Remove useless code & comments.
36560 2004-03-15 Ed Schonberg <schonberg@gnat.com>
36562 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
36563 tagged type is inherited, and the parent operation is not frozen yet,
36564 force generation of a freeze node for the inherited operation, so the
36565 corresponding dispatch entry is properly initialized.
36566 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
36567 when looking for user-defined equality operation.
36569 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
36570 boolean when locating primitive equality of tagged component.
36572 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
36573 bit-aligned field and the right-hand side a string literal, introduce
36574 a temporary before expanding assignment into a loop.
36576 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
36577 priority in full, to ensure that any expanded subepxressions of it are
36578 elaborated in the scope of the init_proc.
36580 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
36581 after object declaration, skipping over code that may have been
36582 generated for validity checks.
36584 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
36585 discriminants, ignore the known discriminants of its full view, if
36586 any, to check legality.
36588 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
36589 component if type has unknown discriminants.
36590 (Analyze_Private_Extension_Declaration): Discriminant constraint is
36591 null if type has unknown discriminants.
36593 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
36594 for end label when present.
36596 * s-fileio.adb (Open): When called with a C_Stream, use given name for
36597 temporary file, rather than an empty string.
36599 2004-03-15 Ed Falis <falis@gnat.com>
36601 * s-thread.adb: Removed, no longer used.
36603 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

36623 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
36624 Insert_Dereference_Action when rewriting an implicit dereference into
36625 an explicit one, this will be taken care of during expansion of the
36626 explicit dereference.
36627 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36628 of non-packed slices, since the dereference action generated by
36629 expansion of the explicit dereference is needed in any case.
36630 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36631 analyze and resolve the rewritten explicit dereference so it is seen
36633 (Insert_Dereference_Action): This procedure is now called only for the
36634 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36635 dereferences that do not come from source (including explicit
36636 dereferences resulting from rewriting implicit ones), but do not
36637 recursively insert a check for the dereference nodes contained within
36639 (Insert_Dereference_Action): Clarify and correct comment.

37516 checks for bitfield creation are triggered.
37517 (finish_record_type): During last pass over the fields, clear
37518 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

37858 2004-01-12 Ed Schonberg <schonberg@gnat.com>
37860 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
37861 generated to rename a generic actual, go to the actual itself, the
37862 subtype is not a user-visible entity.
37864 * sem_ch7.adb (Uninstall_Declarations): If an entity in the visible
37865 part is a private subtype, reset the visibility of its full view, if
37866 any, to be consistent.
37869 * sem_ch12.adb (Analyze_Formal_Package): Diagnose properly an attempt

37904 * 1ssecsta.ads: Default_Secondary_Stack is not a constant since it may
37905 be modified by the binder generated main program if the -D switch is
37908 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
37909 imported functions (since now we expect this to be done for imported
37912 * 5vtaprop.adb: Add several ??? for sections requiring more comments
37913 Minor reformatting throughout

37921 * sprint.adb: Minor updates to avoid -gnatwa warnings
37923 * s-secsta.ads, s-secsta.adb:
37924 (SS_Get_Max): New function to obtain high water mark for ss stack
37925 Default_Secondary_Stack is not a constant since it may be modified by
37926 the binder generated main program if the -D switch is used.
37928 * switch-b.adb: New -Dnnn switch for binder
37931 Make -gnatg imply all warnings currently in -gnatwa

37962 Acquire new SS indication of secondary stack use from ali files
37964 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
37965 (since now we expect this to be done for imported functions)

37970 * bindusg.adb: Add line for new -D switch
37972 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
37973 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
37974 Add circuitry for both records and arrays to avoid gigi
37975 processing if the type involved has non-bit-aligned components
37977 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37978 N_String_Literal node always references an E_String_Literal_Subtype
37979 entity. This may not be true in the future.
37980 (Possible_Bit_Aligned_Component): Move processing of
37981 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37983 * exp_ch6.adb (Expand_Thread_Body): Pick up
37984 Default_Secondary_Stack_Size as variable so that we get value modified
37985 by possible -Dnnn binder parameter.
37987 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37988 (Type_May_Have_Bit_Aligned_Components): New function.
37990 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

38000 unless explicit Pure_Function pragma given, to avoid insidious bug of
38001 call to non-pure imported function getting eliminated.

38004 gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,

38023 * rtsfind.adb (Load_Fail): Give full error message in configurable
38024 run-time mode if all_errors mode is set. This was not done in the case
38025 of a file not found, which was an oversight.
38026 Note if secondary stack unit is used by compiler.
38028 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
38029 ineffective elaborate all pragmas on non-visible packages (this
38030 happened when a renamed subprogram was called). Now the elaborate all
38031 always goes on the package containing the renaming rather than the one
38032 containing the renamed subprogram.
38034 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
38035 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
38037 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
38038 has an Etype that references an E_String_Literal.
38039 (Eval_String_Literal): Avoid assumption that N_String_Literal node
38040 always references an E_String_Literal_Subtype entity. This may not
38041 be true in the future.

38046 * sem_res.adb (Resolve): Specialize msg for function name used in proc
38049 2004-01-05 Ed Falis <falis@gnat.com>

38057 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
38060 * make.adb (Gnatmake): Special process for files to compile/check when
38061 -B is specified. Fail when there are only foreign mains in attribute
38062 Main of the project file and -B is not specified. Do not skip bind/link
38063 steps when -B is specified.

38088 -gnatwa warning on static condition.
38090 2004-01-05 Doug Rupp <rupp@gnat.com>
38092 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
38094 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
38096 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
38097 all attributes, including read-only attribute.
38099 2004-01-05 Pascal Obry <obry@gnat.com>

38102 library naming scheme.
38104 * mlib-prj.adb (Build_Library): Generate different names for the static
38105 or dynamic version of the GNAT runtime. This is needed to support the
38106 new shared library naming scheme.

38108 based on the new naming scheme.
38110 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
38111 scheme for the shared runtime libraries.
38114 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
38116 (install-gnatlib): Do not create symlinks for shared libraries.
38117 (gnatlib-shared-default): Idem.
38118 (gnatlib-shared-dual-win32): New target. Not used for now as the
38119 auto-import feature does not support arrays/records.
38120 (gnatlib-shared-win32): Do not create copy for the shared libraries.
38121 (gnatlib-shared-vms): Fix shared runtime libraries names.
38123 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
38124 dependent runtime shared library name.
38126 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
38128 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
38131 2004-01-05 Ed Schonberg <schonberg@gnat.com>
38133 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
38134 protected objects when allocator has a subtype indication, not a
38135 qualified expression. Note that qualified expressions may have to be
38136 checked when limited aggregates are implemented.
38138 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
38139 pure, emit warning.
38140 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
38141 subprogram is imported, remove warning.
38143 2004-01-05 Geert Bosch <bosch@gnat.com>
38145 * s-poosiz.adb: Update copyright notice.
38146 (Allocate): Use Task_Lock to protect against concurrent access.

38185 * cstand.adb (Create_Standard): Change the way how the declaration of
38186 the Duration type is created (making it the same way as it is for all
38187 the other standard types).
38189 2003-12-17 Robert Dewar <dewar@gnat.com>

38199 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
38200 are universal and already analyzed, as can occur in constrained
38201 subcomponents that depend on discriminants, when one constraint is a
38204 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
38205 type Any_Fixed is legal as the argument of a conversion, if only one

38285 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
38286 Minor reformatting throughout
38288 2003-12-11 Ed Schonberg <schonberg@gnat.com>
38290 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
38291 bounds of a loop, create a separate block in order to generate proper
38292 cleanup actions to prevent memory leaks.
38294 * sem_res.adb (Resolve_Call): After a call to
38295 Establish_Transient_Scope, the call may be rewritten and relocated, in

38298 * sem_util.adb: (Wrong_Type): Refine previous fix.
38299 Fixes ACATS regressions.
38302 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
38305 2003-12-08 Jerome Guitton <guitton@act-europe.fr>

38308 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
38311 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
38314 2003-12-08 Robert Dewar <dewar@gnat.com>
38316 * 7sintman.adb: Minor reformatting
38318 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
38319 standard linker options to get standard libraries linked. We now plan
38320 to provide dummy versions of these libraries to match the appropriate
38321 configurable run-time (e.g. if a library is not needed at all, provide
38322 a dummy empty library).
38324 * targparm.ads: Configurable_Run_Time mode no longer affects linker
38325 options (-L parameters and standard libraries). What we plan to do is
38326 to provide dummy libraries where the libraries are not required.
38328 * gnatbind.adb: Minor comment improvement
38330 2003-12-08 Javier Miranda <miranda@gnat.com>
38332 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
38333 aggregate in the parent. Otherwise constants with limited aggregates
38334 are not supported. Add new formal to pass the component type (Ctype).
38335 It is required to call the corresponding IP subprogram in case of
38336 default initialized components.
38337 (Gen_Assign): In case of default-initialized component, generate a
38338 call to the IP subprogram associated with the component.

38753 Adding a check to see whether the Interrupt_ID we want to unmask is in
38754 the range of Keep_Unmasked (in procedure Interrupt_Self_Process). The
38755 reason is that the index type of the Keep_Unmasked array is not always

40120 Fix typos in various comments
40121 Update copyright notice in spec
40123 2003-10-21 Gary Dismukes <dismukes@gnat.com>
40126 (Component_Needs_Simple_Initialization): Return False when the type is a
40127 packed bit array. Revise spec comments to document this case.
40130 (Expand_Pragma_Import): Set any expression on the imported object to
40131 empty to avoid initializing imported objects (in particular this
40132 covers the case of zero-initialization of bit arrays).

42163 (general) Add @./@: where approriate, and two spaces after the
42164 full stop at the end of a sentence. Use @samp markup when
42165 referring concrete lexical entities (keywords, attribute names
42166 etc.), and @syntax for ARM grammar elements. Use @r for English

42179 2001-12-22 Florian Weimer <fw@deneb.enyo.de>
42181 * make.adb (Add_Switch): Make Generic_Position a procedure. The
42182 function approach did not work well because of a side effect (the
42183 function call could reallocate the table which was being indexed
42184 using its result). Fixes ada/4851.

42243 Add 2001 to copyright date
42245 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
42246 need to force universal inlining for these cases.
42248 2001-12-19 Arnaud Charlet <charlet@gnat.com>
42250 * s-taprob.adb: Minor clean ups so that this unit can be used in

42277 the argument of an initialization procedure.
42279 * trans.c (tree_transform, case of arithmetic operators): If result
42280 type is private, the gnu_type is the base type of the full view,

42370 Above changes fix problem with length computation for supernull arrays
42371 where Max (Len, 0) wasn't getting applied due to the Unsigned
42372 conversion used by Compute_Length.

42462 When using a project file, fail if specified executable is relative
42463 path with directory information, and prepend executable, if not
42464 specified as an absolute path, with the exec directory. Make sure
42465 that only one -o switch is transmitted to the linker.
42467 * prj-attr.adb (Initialization_Data): Add project attribute Exec_Dir

42548 there could be a real problem here with an uninitialized reference
42549 to Hbound, but no actual example of failure has been found.
42551 2001-12-17 Laurent Pautet <pautet@gnat.com>
42554 Fix comment of Shutdown_Socket and Close_Socket. These functions
42555 should not fail silently because if they are called twice, this
42556 probably means that there is a race condition in the user program.
42557 Anyway, this behaviour is consistent with the rest of this unit.
42558 When an error occurs, an exception is raised with the error message
42559 as exception message.
42561 2001-12-17 Robert Dewar <dewar@gnat.com>

43893 instead of the previous simple checksum algorithm.
43894 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43895 (Set_Source_Table): idem.
43898 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43899 instead of simple checksum.
43900 (CRC_Match): new function.
43901 (CRC_Error): new constant.
43903 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43904 a CRC now and not a simple checksum. A CRC uses lower-case hex
43905 letters, fixes ambiguity in parsing.
43907 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43908 is what this variable will store.
43910 * bcheck.adb: Change reference to chechsum in comments by CRC.
43911 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43912 rename All_Checksum_Match to All_CRC_Match. Change due to API
43913 renaming since now GNAT does not use a simple checksum but a
43914 CRC using GNAT.CRC32.
43916 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43917 now and not anymore a simple checksum.

43956 * types.adb (Hex): Use lowercase for the letter part.
43958 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43959 for a word. This is currently used only for CRC. In previous version,
43960 the checksum was using a representation with all letter being
43961 upper-case. With the new implementation (using CRC) we do not remove
43962 the 32th bit of the CRC, so we can have an upper-case starting letter
43963 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43964 It is ambigous since the CRC was optional and could be followed by
43965 options like EB, EE. So now this routines uses lower-case letter for
43966 the hexadecimal representation. Strange enough only lower case letters
43967 where checked in Scan_ALI (even if this was not a possible case).
43969 * gnatvsn.ads (Library_Version): changed to 3.15a.
43971 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43974 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
