1830 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1831 Orig_Prev to Prev in the case where the actual is N_Function_Call or
1832 N_Identifier. This was interfering with other cases that are rewritten

4009 the designated type and its ancestors, but depending on the currently
4010 visible private parts, this caused false negatives. We now uniformly
4011 rely on checks made at the point where the RACW type is declared.

4020 restricting use of predefined assignment with tagged types that have
4022 (Analyze_Object_Declaration): Relax the check regarding deferred
4023 constants declared in scopes other than packages since they can be
4024 completed with pragma Import.
4025 Add missing escaping of all-caps word 'CPP' in error messages.
4026 (Build_Discriminated_Subtype): Do not inherit representation clauses
4027 from parent type if subtype already carries them, because they are
4028 inherited earlier during derivation and already include those that may
4029 come from a partial view.
4031 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):

4068 through dispatching, never through static calls).
4069 (Collect_Interps): When only one interpretation has been found, set N's
4070 Entity and Etype to that interpretation, otherwise Entity and Etype may
4071 still refer to an interpretation that was ignored by Add_One_Interp,
4072 in which case would end up with being marked as not overloaded but with
4073 an Entity attribute not pointing to its (unique) correct interpretation.

8198 clauses for inherited components of a type extension.
8199 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for

8377 (Process_Subtype): The subtype inherits the Known_To_Have_Preelab_Init
8379 (Derive_Subprograms): Handle derivations of predefined primitives
8380 after all the user-defined primitives to ensure that they are
8381 found in proper order in instantiations.

8383 of Related_Interface to Related_Type.
8384 (Record_Type_Declaration): Minor reordering of calls to decorate the

8386 before setting its Is_Tag attribute.
8387 (Analyze_Subtype_Declaration): In the case of subtypes with
8388 Private_Kind, inherit Known_To_Have_Preelab_Init from the parent.

8393 * sem_ch4.adb (Analyze_Selected_Component): Include the requeue
8394 statement to the list of contexts where a selected component with a
8395 concurrent tagged type prefix should yield a primitive operation.
8396 (Find_Primitive_Operation): Handle case of class-wide types.
8397 (Analyze_Overloaded_Selected_Component): If type of prefix is
8398 class-wide, use visible components of base type.
8399 (Resolve_Selected_Component): Ditto.
8400 (Try_Primitive_Operation, Collect_Generic_Type_Ops): If the type is a
8401 formal of a generic subprogram. find candidate interpretations by
8402 scanning the list of generic formal declarations.:
8403 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
8404 type from a limited_with_clause, and the full view is available, use it
8405 for subsequent semantic checks.
8406 (Check_Misspelled_Selector): Use Namet.Sp.Is_Bad_Spelling_Of function
8407 (Find_Primitive_Operation): New function.
8408 (Analyze_Overloaded_Selected_Component): insert explicit dereference
8409 only once if several interpretations of the prefix yield an access type.
8410 (Try_Object_Operation): Code and comment cleanup.
8411 (Analyze_Selected_Component): Reorder local variables. Minot comment and
8412 code reformatting. When the type of the prefix is tagged concurrent, a

8439 and those of the target interface primitive.
8440 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8441 Timed_Entry_Call): Analyze the triggering statement as the first step of

8445 replicated some of the select statements. In case the Expander is
8446 disabled, perform regular analysis.
8447 (Check_Triggering_Statement): New routine.
8448 (Analyze_Requeue): Exclude any interpretations that are not entries when
8449 checking overloaded names in a requeue. Also test type conformance for
8450 matching interpretations rather than requiring subtype conformance at
8451 that point to conform with the RM's resolution rule for requeues.

8487 latest Ada 2005 rules about renaming and 'Access of
8488 discriminant-dependent components.

9042 a predefined entity (as happens for array index types), the line is set
9044 Add support for parsing multiple array index types info, or
9045 multiple inherited interfaces info. This information cannot be stored
9046 in Xref_Entity_Record, which only supports a single instance of Tref_*,
9047 and is therefore stored in the list of references instead. It has a

9062 Dismukes). After this patch there is no need to perform any
9063 additional management on these nodes in Expand_Interface_Actuals.
9065 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9066 that handles use of 'Access and 'Unchecked_Access applied to
9067 actuals covering interface types. Such code is now
9068 centralized in Expand_N_Attribute_Reference.

9112 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9113 used by VxWorks targets to have access to task-specific data and be
9114 able to extract the stack boundaries for stack checking.
9115 Use system-vms-ia64.ads on ivms.
9117 * Make-lang.in: Update dependencies.

9158 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9159 association for an access component, add an association with null as
9160 the expression. Remove testing for array subtypes and the setting in
9161 that case of Ctyp to the array component type, which prevented proper
9162 inclusion of an association for null-initialized arrays. Collapse
9163 condition that tests for array subtypes into just a test of
9164 Is_Partially_Initialized_Type (which already covers arrays anyway).

9181 * sem_ch4.adb: Minor code and comment reformatting.
9182 (Analyze_Allocator): When the designated type of an unconstrained
9183 allocator is a record with unknown discriminants or an array with

9411 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9413 2007-09-26 Javier Miranda <miranda@adacore.com>
9414 Eric Botcazou <ebotcazou@adacore.com>
9417 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9418 indirection added to the HT_Link component of the TSD. This is required
9419 to statically allocate the TSD.
9422 Minor reordering of the declarations in the private part. Required to
9423 add a level of indirection to the contents of the TSD component HT_Link.
9424 This is required to statically allocate the TSD.
9426 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9427 Is_Statically_Allocated set from constant objects.
9428 Do not make exported constants created by the compiler volatile.
9429 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9432 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9433 before returning them.
9435 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9436 public part of the package.
9437 (Make_DT): Move HT_Link component out of the TSD record. For this
9438 purpose Make_DT now declares a separate object that stores the
9439 HT_Link value, and initializes the TSD component with the address
9440 of this new object. The addition of this level of indirection is
9441 required to statically allocate the TSD because the TSD cannot
9442 have variable components.
9443 (Expand_Interface_Conversion): Improve the expanded code.
9444 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9446 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9447 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9448 if we are building static dispatch tables then we must not generate
9449 extra code to register the primitive because the dispatch table will
9450 be built at the end of the library package; otherwise we notify that
9451 we cannot build the static dispatch table.
9453 2007-09-26 Robert Dewar <dewar@adacore.com>
9455 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
9458 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
9459 (Analyze_Record_Representation_Clause): Suppress junk warning for
9460 missing component clause.
9461 (Analyze_Attribute_Definition_Clause, case Address): Apply the special
9462 tests for controlled type overlay to composites with controlled
9464 (Analyze_Record_Representation_Clause): Add reference for component name
9466 2007-09-26 Javier Miranda <miranda@adacore.com>
9467 Gary Dismukes <dismukes@adacore.com>

9470 for thunks associated with interface types.
9472 * einfo.ads: Improve documentatation of Is_Internal
9473 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9474 associated with interface types.
9475 Extensive comment fixes regarding flags that appear in all entities. The
9476 documentation is now consistent for all such flags (there were a number
9477 of errors in the documentation in this regard).
9479 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9481 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9482 of these procedures are passed a function call that already has
9483 build-in-place actuals (testing new flag
9484 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9485 the case where processing continues.
9486 (Expand_Call): If the call is generated from a thunk body then we
9487 propagate the extra actuals associated with the accessibility
9488 level of the access type actuals.
9490 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9491 of each extra formal of a protected operation to reference the
9492 corresponding extra formal of the subprogram denoted by the
9493 operation's Protected_Body_Subprogram.
9495 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9496 N_Function_Call nodes.
9498 2007-09-26 Robert Dewar <dewar@adacore.com>
9500 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9502 * debug.adb: Add d.s flag.
9504 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9506 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9507 debug variable so that it won't be initialized when pragma
9508 Initialize_Scalars is in effect.
9510 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9512 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9513 initialization of a full view. This is moved to
9514 Analyze_Package_Specification.
9516 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9517 preelaborable initialization of a full view in entity loop.
9518 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9519 its child units are use-visible only if they are visible child units.
9521 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9522 whether an expression can be used within a type declaration that
9523 requires preelaborable init.
9524 (Check_Components): Replace inline code that does partial checking for
9525 preelaborable default expressions with call to
9526 Is_Preelaborable_Expression.
9527 (Has_Preelaborable_Initialization): In the case of a generic actual
9528 subtype, (that is, Is_Generic_Actual is True), return the result of
9529 applying Has_Preelaborable_Initialization to the generic actual's base
9532 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9534 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9535 call to Jan_1_Day _Of_Week to optimize its performance.
9536 (Is_Leap): Move the routine to the scope of Week_In_Year.
9537 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9538 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9539 avoids calling Time_Of and Split, thus making it more efficent.
9540 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9542 * g-calend.ads (Week_In_Year): Change comment to reflect new
9545 2007-09-26 Emmanuel Briot <briot@adacore.com>
9547 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9548 Command_Line): New types
9549 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9550 support for defining how switches can be grouped on a command line (as
9551 is the case for -gnatw... for GNAT), and how simple switches can be
9552 used as aliases for more complex switches (-gnatwa is same as
9554 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9555 (Start, Current_*): New subprograms
9556 Added support for parsing an array of strings in addition to the real
9558 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9559 be moved from the body to the private part of the spec.
9560 (*): All subprograms now have an extra parameter with default value to
9561 specify which parser should be used. For backward compatibility, it
9562 defaults to parsing the command line of the application. They were also
9563 modified to properly handle cases where each of the argument does not
9564 start at index 1 (which is always true for Ada.Command_Line, but not
9565 when processing any Argument_List).
9566 (Free): New subprogram
9567 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9568 Argument): New subprograms
9569 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9570 special characters like ':', '=',... are now handled in a single place,
9571 which makes the code more extensible eventually.
9572 (Getopt, Full_Switch): When the switch was returned as part of the
9573 special character '*', make sure it is prepended by the switch character
9574 ('-' in general), so that the application knows whether "foo" or "-foo"
9575 was specified on the command line.
9577 2007-09-26 Florian Villoing <villoing@adacore.com>
9579 * g-dirope.adb (Remove_Dir): In case we are removing directories
9580 recursively, make sure that if an exception is raised during the
9581 processing, the current working directory is reset to its initial
9582 value before propagating the exception.
9584 2007-09-26 Vincent Celier <celier@adacore.com>
9586 * gnatbind.adb: If there are several ALI files specified and there is
9587 a main program to bind, the first ALI is expected to contain the main
9588 subprogram and the names of the binder generated files will be derived
9589 from the first ALI file name.
9590 (Gnatbind): Fix insertion character in invocation of Error_Msg
9592 2007-09-26 Vincent Celier <celier@adacore.com>
9594 * gnatcmd.adb (Check_Files): Do not include sources that have been
9595 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9597 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9599 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9600 information about each of its index types, following the type
9601 reference for its component type.
9603 2007-09-26 Vincent Celier <celier@adacore.com>
9605 * make.adb: (Kill): New procedure (__gnat_kill imported)

9612 sources, so that the correct paths will be found.
9614 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
9616 2007-09-26 Vincent Celier <celier@adacore.com>
9618 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9620 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9621 Replace components Compiler_Min_Options and Binder_Min_Options with
9622 Compiler_Required_Switches and Binder_Required_Switches in record
9624 Remove components Default_Language and Config in Project_Tree_Data,
9627 * prj-attr.adb: New attributes Required_Switches (<language>) in
9628 packages Compiler and Binder.
9630 * prj-nmsc.adb: Major rewrite of the processing of configuration
9631 attributes for gprbuild. No impact on GNAT tools.
9633 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9634 process configuration attributes: this is done in Prj.Nmsc.Check.
9635 (Recursive_Process): Make a full copy of packages inherited from project
9636 being extended, instead of a shallow copy.
9637 (Process_Project_Tree_Phase_1): New procedure

9639 (Process): Implementation now uses the two new procedures
9641 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9642 from the project config, not the tree config that no longer exists.

9668 ancestor of the derived type, the operations are inherited from the
9669 primary dispatch table of the parent.
9670 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9671 when the context is an explicit type conversion.

9970 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
9971 create an abstract subprogram in the case of 'Input. For 'Output we now
9972 create a real spec/body when the type is abstract, since it can
9973 potentially be called.
9974 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9975 body for 'Output when the type is abstract (only the creation of the
9976 body for 'Input is excluded when the type is abstract).
9977 (Stream_Operation_OK): Add an additional condition in the return
9978 statement, so that False will be returned for TTS_Stream_Input if the
9979 associated tagged type is an abstract extension. Add comments for
9981 (Expand_N_Object_Declaration): For the case of a shared passive
9982 variable, insert init proc call only after the shared variable
9983 procedures have been processed, because the IP call needs to undergo
9984 shared passive variable reference expansion, which requires these
9985 procedures to be available (and elaborated).

9996 and the value of the discriminant is the discriminant of the enclosing
9997 type, retrieve its value from the aggregate itself, where it must have
10000 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10001 to remove other spurious ambiguities on arithmetic operations involving
10002 literals and addresses, on systems where Address is a visible integer
10003 type, when the operator is called in functional notation.
10004 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10005 is legal when the types match, even if the operation is currently
10008 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10010 * sem_ch12.adb (Build_Local_Package): A formal package with no
10011 associations is legal if all formals have defaults. It is not
10012 equivalent to a formal declared with a box.

10130 (Write_Entity_Flags): Write the status of flag Is_Raised.
10131 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10132 spurious ambiguities when integer literals appear in the context of an

10158 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10159 occurring in the list of entities to qualify, and do not attempt to

10193 value of the right operand directly.
10195 * stringt.adb (Store_String_Chars): Optimize by growing the
10196 String_Chars table all at once, rather than appending characters one by
10198 (Write_String_Table_Entry): If the string to be printed is very long,
10199 just print the first few characters, followed by the length. Otherwise,
10200 doing "pn(n)" in the debugger can take an extremely long time.
10202 * sem_prag.adb (Process_Interface_Name): Replace loop doing

10220 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10222 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10223 flag, for effiency. It is called when analyzing arithmetic operators
10224 and also for actuals in calls that are universal_integers. The flag is
10225 set for the predefined type address, and for any type or subtype
10228 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10229 Universal_Integer, when the formal is a descendent of address and the
10230 call appears in user code.

10312 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10313 and the entity of the renaming declaration.
10314 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10315 part of the name of a variable that has a Debug_Renaming_Link.
10317 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10318 special type to be associated with variables that provide debugger
10319 encodings for renaming declarations.

10322 Ed Schonberg <schonberg@adacore.com>
10323 Javier Miranda <miranda@adacore.com>
10325 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10326 ancestor part given by an aggregate to test for an unchecked conversion,
10327 since this can occur in some cases when the ancestor part is a function
10328 call, and we don't want to fall into the recursive call to this
10329 procedure in that case.
10331 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10332 stream attributes on limited types to account for user-specified
10333 attributes as well as whether Input (resp. Output) becomes available
10334 due to Read (resp. Write) being available for the type. Change Boolean
10335 variable to the more accurate name
10336 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10337 double-"not" predicate at beginning of return statement to more
10338 understandable form.
10340 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10341 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10342 in a block statement and use that as the first statement of the
10343 expanded return rather than incorrectly using the handled sequence as
10344 the first statement.
10346 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10347 operation, generate an explicit freeze node for it rather than
10348 generating extra formals, to ensure that gigi has the proper order of
10349 elaboration for anonymous subtypes in the signature of the subprograms.
10350 (Build_In_Place_Formal): Move assertion to beginning of loop.
10351 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10352 applied to a function call (occurs for some cases of 'Input).

10354 applied to a function call (occurs for some cases of 'Input).
10356 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10357 2005, generate an extended return statement enclosing the result object
10360 * freeze.adb (Freeze_Record_Type): Extend the current management of
10361 components that are access type with an allocator as default value: add
10362 missing support to the use of qualified expressions of the
10363 allocator (which also cause freezing of the designated type!)
10364 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10365 dispatching operation, since extra formals may be needed by calls to
10366 build-in-place functions (such as stream 'Input).
10368 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10369 formals for 'Constrained and accessibility level in the case of a
10370 predefined dispatching operation.
10372 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10373 point, no need to find the parent node.
10375 2007-08-16 Javier Miranda <miranda@adacore.com>
10377 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10378 and entry barriers.
10380 2007-08-16 Javier Miranda <miranda@adacore.com>
10382 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10383 is not really required and can introduce regression with the debugger.
10384 The original problem is fixed with the patch written for checks.adb.
10386 2007-08-16 Thomas Quinot <quinot@adacore.com>
10388 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
10389 Range_Check on Allocated_Table.

10393 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
10394 Including_Non_Switch set to False.
10395 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10396 Including_Non_Switch set to False.
10398 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10399 parameter Including_Non_Switch, defaulted to True. When
10400 Including_Non_Switch is False, options that are not switches and
10401 appear as relative path are not converted to absolute paths.
10403 2007-08-16 Nicolas Roche <roche@adacore.com>
10405 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
10408 * Make-lang.in: Update dependencies

10412 * sem_ch10.adb (Has_With_Clause): If the name of the with clause
10413 currently inspected is a selected component, retrieve the entity of
10415 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
10416 from the immediate ancestor of Main_Unit_Entity.
10417 (Install_Limited_Withed_Unit): Do not install the limited view of
10418 package P if P is reachable through an ancestor chain from package C
10419 and C also has a with clause for P in its body.
10420 (Has_Limited_With_Clause): New routine.
10421 (Has_With_Clause): New routine.
10423 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10425 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10426 generic for an enclosing instance is a global reference, even though
10427 its scope is the enclosing instance.
10429 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10430 Javier Miranda <miranda@adacore.com>
10432 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
10433 initialize a limited object.
10434 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
10436 Make sure Has_Complex_Representation is inherited by derived type.
10438 2007-08-16 Robert Dewar <dewar@adacore.com>
10440 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
10443 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10445 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10446 implements an operation inherited from a progenitor interface, verify
10447 that they are subtype-conformant.
10449 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
10450 Bob Duff <duff@adacore.com>
10451 Nicolas Setton <setton@adacore.com>
10453 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10454 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10455 the statement which is being resolved comes from a predefined library
10456 unit, all non-predefined library interpretations are skipped.
10457 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10458 but the "&" is user defined, give an error, because the folding would
10461 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
10462 the parser has folded a long sequence of concatenations of string
10465 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10466 and "JMP_BUF" variables as artificial.
10467 (N_String_Literal): Do not use alloca for very long string literals. Use
10468 xmalloc/free instead. Otherwise the stack might overflow.
10470 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
10473 2007-08-16 Vincent Celier <celier@adacore.com>
10475 * vms_conv.adb (Process_Argument): Ensure that project related options
10476 are not put in the -cargs section when using GNAT COMPILE.
10478 2007-08-16 Robert Dewar <dewar@adacore.com>
10480 * gnat_ugn.texi: Add note on preprocessing (output file not written)
10482 2007-08-16 Thomas Quinot <quinot@adacore.com>

10507 s-osinte-freebsd.ads, s-osinte-freebsd.adb: Minor reformatting.
10509 * styleg.adb, styleg.ads, stylesw.adb, stylesw.ads: implement style
10510 switch -gnatyS. Enable -gnatyS in GNAT style check mode
10512 2007-08-14 Robert Dewar <dewar@adacore.com>
10513 Ed Schonberg <schonberg@adacore.com>
10515 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10516 Suppress unmodified in-out parameter warning in some cases
10517 This patch is a also fairly significant change to the way suppressible
10518 checks are handled.
10520 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10521 needed for access to concurrent record types generated by the expander.
10522 (Generate_Range_Check): When generating a temporary to capture the
10523 value of a conversion that requires a range check, set the type of the
10524 temporary before rewriting the node, so that the type is always
10525 properly placed for back-end use.
10526 (Apply_Float_Conversion_Check): Handle case where the conversion is
10528 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10529 for a protected type in order to examine its discriminants.

10533 Ed Schonberg <schonberg@adacore.com>
10534 Thomas Quinot <quinot@adacore.com>
10536 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10537 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10538 tests optimized out.
10540 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10541 (Get_Allocator_Final_List): For the case of an anonymous access type
10542 that has a specified Associated_Final_Chain, do not go up to the
10544 (Expand_N_Type_Conversion): Test for the case of renamings of access
10545 parameters when deciding whether to apply a run-time accessibility
10547 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10548 aggregate code before allocator, and ahead of declaration for
10549 temporary, to prevent access before elaboration when the allocator is
10550 an actual for an access parameter.
10551 (Expand_N_Type_Conversion): On an access type conversion involving an
10552 access parameter, do not apply an accessibility check when the
10553 operand's original node was an attribute other than 'Access. We now
10554 create access conversions for the expansion of 'Unchecked_Access and
10555 'Unrestricted_Access in certain cases and clearly accessibility should
10556 not be checked for those.
10558 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10559 includes a type conversion of a packed component that has been expanded,
10560 recover the original expression for the object, and use this expression
10561 in the post-call assignment statement, so that the assignment is made
10562 to the object and not to a back-end temporary.
10563 (Freeze_Subprogram): In case of primitives of tagged types not defined
10564 at the library level force generation of code to register the primitive
10565 in the dispatch table. In addition some code reorganization has been
10566 done to leave the implementation clear.
10567 (Expand_Call): When expanding an inherited implicit conversion,
10568 preserve the type of the inherited function after the intrinsic
10569 operation has been expanded.
10571 * exp_ch2.ads, exp_ch2.adb
10572 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10573 of an entry formal appearing in an assignment statement does not assign
10575 (Expand_Current_Value): Instead of calling a routine to determine
10576 whether the prefix of an attribute reference should be optimized or
10577 not, prevent the optimization of such prefixes all together.
10579 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10580 component whose prefix is known to be of an access type is an implicit
10581 dereference and does not assign to the prefix.
10583 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10584 Robert Dewar <dewar@adacore.com>
10586 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10587 itype is visited, make an entry into table to link associated node and
10589 Add comments and correct harmless error in Build_NCT_Hash_Tables
10590 (Array_Aggr_Subtype): Associate each itype created for an index type to
10591 the corresponding range construct, and not to the aggregate itself. to
10592 maintain a one-to-one correspondence between itype and its associated
10593 node, to prevent errors when complex expression is copied.
10594 Fix mishandling of multiple levels of parens
10596 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10597 treatment of limited views uniform for all visible declarations in a
10598 limited_withed package.
10599 (New_Copy_Tree): If hash table is being used and itype is visited,
10600 make an entry into table to link associated node and new itype.
10601 (Resolve_Record_Aggregate): Do not add an others box association for a
10602 discriminated record component that has only discriminants, when there
10603 is a box association for the component itself.
10605 * par-ch4.adb: Fix mishandling of multiple levels of parens
10607 2007-08-14 Robert Dewar <dewar@adacore.com>
10609 * comperr.adb: Fix problem with suppressing warning messages from gigi
10611 * erroutc.ads, erroutc.adb, errout.ads,
10612 errout.adb (Write_Eol): Remove trailing spaces before writing the line
10613 (Write_Eol_Keep_Blanks): New procedure to write a line, including
10614 possible trailing spaces.
10615 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
10616 Fix problem with suppressing warning messages from back end
10617 Improve handling of deleted warnings
10620 Fix problem with suppressing warning messages from back end
10621 Handle setting of Static_Dispatch_Tables flag.
10624 Fix problem with suppressing warning messages from back end
10626 * exp_intr.adb: Improve handling of deleted warnings

10641 Gary Dismukes <dismukes@adacore.com>
10643 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
10644 to make treatment of limited views uniform for all visible declarations
10645 in a limited_withed package.
10646 Improve warnings for in out parameters
10647 (Set_Related_Interaface/Related_Interface): Allow the use of this
10648 attribute with constants.

10652 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10653 generation of a freezing node to ensure proper management of null
10654 excluding access types in the backend.
10655 (Create_Extra_Formals): Test base type of the formal when checking for
10656 the need to add an extra accessibility-level formal. Pass the entity E
10657 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10658 originally being done in a couple of cases), to ensure that the
10659 Extra_Formals list gets set on the entity E when the first entity is
10661 (Conforming_Types): Add missing calls to Base_Type to the code that
10662 handles anonymous access types. This is required to handle the
10663 general case because Process_Formals builds internal subtype entities
10664 to handle null-excluding access types.
10665 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10666 functions that need it, even when not marked Requires_Overriding.
10667 Improve warnings for in out parameters
10668 (Analyze_Function_Return): Warn for disallowed null return
10669 Warn on return from procedure with unset out parameter
10670 Ensure consistent use of # in error messages
10671 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10672 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10673 the implicit conversion of the expression done for anonymous access
10674 types. This is required to generate the code of the null excluding
10675 check (if required).
10677 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10678 A formal parameter is never publicly referenceable outside of its body.
10679 (Check_References): For an unreferenced formal parameter in an accept
10680 statement, use the same warning circuitry as for subprogram formal
10682 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10683 Output_Unreferenced_Messages, containing the part of that routine that
10684 is now reused for entry formals as described above.
10685 (Goto_Spec_Entity): New function
10686 (Check_References): Do not give IN OUT warning for dispatching operation
10687 Improve warnings for in out parameters
10688 (Test_Ref): Check that the entity is not undefinite before calling
10689 Scope_Within, in order to avoid infinite loops.
10690 Warn on return from procedure with unset out parameter
10691 Improved warnings for unused variables

10697 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10698 (Expand_N_Attribute_Reference): Further unify the handling of the
10699 three forms of access attributes, using common code now for all three
10700 cases. Add a test for the case of applying an access attribute to
10701 an explicit dereference when the context is an access-to-interface
10702 type. In that case we need to apply the conversion to the prefix
10703 of the explicit dereference rather than the prefix of the attribute.
10704 (Attribute_Version, UET_Address): Set entity as internal to ensure
10705 proper dg output of implicit importation.
10706 (Expand_Access_To_Type): Removed.
10707 (Expand_N_Attribute_Reference): Merge the code from the three cases
10708 of access attributes, since the processing is largely identical for
10709 these cases. The substantive fix here is to process the case of a
10710 type name prefix (current instance case) before handling the case
10711 of interface prefixes.

10718 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10719 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10720 type that is an anonymous access to controlled object, establish
10721 an associated finalization chain to avoid corrupting the global
10722 finalization list when a dynamically allocated object designated
10723 by such a component is deallocated.
10724 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10725 functions that need it, even when not marked Requires_Overriding.
10726 (Initialize_Tag): Replace call to has_discriminants by call to
10727 Is_Variable_Size_Record in the circuitry that handles the
10728 initialization of secondary tags.
10729 (Is_Variable_Size_Record): New implementation.
10730 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10731 Suppress_Initialization pragma for a derived type.
10732 (Is_Variable_Size_Record): New subprogram.
10733 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10734 initial version of this routine and also fixes problems causing
10735 incomplete initialization of the table of interfaces.
10736 (Build_Init_Procedure): Improve the generation of code to initialize the
10737 the tag components of secondary dispatch tables.
10738 (Init_Secondary_Tags): New implementation that simplifies the previous
10739 version of this routine.
10740 (Make_DT): Add parameter to indicate when type has been frozen by an
10741 object declaration, for diagnostic purposes.
10742 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10743 diagnose attemps to freeze a subprogram when some untagged type of its
10744 profile is a private type whose full view has not been analyzed yet.
10745 (Freeze_Array_Type): Generate init proc for packed array if either
10746 Initialize or Normalize_Scalars is set.
10747 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10748 constructing the new profile, copy the null_exclusion indicator for each
10749 parameter, to ensure full conformance of the new body with the spec.
10751 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10752 Create wrappers for constructor functions that need it, even when not
10753 marked Requires_Overriding.
10754 (Covers): Handle properly designated types of anonymous access types,
10755 whose non-limited views are themselves incomplete types.
10756 (Add_Entry): Use an entity to store the abstract operation which hides
10758 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.

10760 initialization aggregate.
10761 (Function_Interp_May_Be_Hidden): Rename to
10762 Function_Interp_Has_Abstract_Op.
10763 (Has_Compatible_Type): Remove machinery that skips interpretations if
10764 they are labeled as potentially hidden by an abstract operator.
10765 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10766 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10767 (Write_Overloads): Output the abstract operator if present.
10768 (Add_Entry): Before inserting a new entry into the interpretation table
10769 for a node, determine whether the entry will be disabled by an abstract

10772 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10774 (Function_Interp_May_Be_Hidden): New routine.
10775 (Has_Compatible_Type): Do not consider interpretations hidden by

10785 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
10786 types declared in the declarative part of a nested package body or in
10787 the proper body of a stub.
10788 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10789 of the same dispatch table slot to renamed primitives.
10790 (Make_Select_Specific_Data_Table): Handle private types.
10791 (Tagged_Kind): Handle private types.
10792 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10793 output of implicit importation and exportation.
10794 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10795 first formal of the thunk is always associated with the controlling
10796 type. In addition perform the following code cleanup: remove formal
10797 Thunk_Alias which is no longer required, cleanup evaluation of the
10798 the controlling type, and update the documentation.
10799 Replace occurrence of Default_Prim_Op_Count by
10800 Max_Predef_Prims. Addition of compile-time check to verify
10801 that the value of Max_Predef_Prims is correct.
10802 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10803 (Make_DT): Add parameter to indicate when type has been frozen by an
10804 object declaration, for diagnostic purposes.
10805 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10806 construction of statically allocated dispatch tables.
10807 (Make_DT): In case of library-level tagged types export the declaration

10810 tables. Take care of building tables for asynchronous interface types
10811 (Make_Tags): New subprogram that generates the entities associated with
10812 the primary and secondary tags of Typ and fills the contents of Access_
10813 Disp_Table. In case of library-level tagged types imports the forward
10814 declaration of the primary tag that will be declared later by Make_DT.
10815 (Expand_Interface_Conversion): In case of access types to interfaces
10816 replace an itype declaration by an explicit type declaration to avoid

10823 * exp_util.ads, exp_util.adb:
10824 This patch replaces a number of occurrences of explicit tests for N_Null
10825 with calls to Known_Null. This improves tracking of null values, since
10826 Known_Null also catches null constants, and variables currently known to
10827 be null, so we get better tracking.
10828 (Ensure_Defined): create an itype reference only in the scope of the
10830 (Side_Effect_Free): A selected component of an access type that
10831 denotes a component with a rep clause must be treated as not
10832 side-effect free, because if it is part of a linked structure its
10833 value may be affected by a renaming.
10834 (Expand_Subtype_From_Expr): For limited objects initialized with build
10835 in place function calls, do nothing; otherwise we prematurely introduce
10836 an N_Reference node in the expression initializing the object, which
10837 breaks the circuitry that detects and adds the additional arguments to
10838 the called function. Bug found working in the new patch for statically
10839 allocated dispatch tables.
10840 (Is_Library_Level_Tagged_Type): New subprogram.
10841 (Remove_Side_Effects): If the expression of an elementary type is an
10842 operator treat as a function call.
10843 (Make_Literal_Range): If the index type of the array is not integer, use
10844 attributes properly to compute the constraint on the resulting aggregate
10847 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10848 class-wide type whose base type is an incomplete private type, leave
10849 class-wide type unfrozen so that freeze nodes can be generated
10850 properly at a later point.
10851 (Freeze_Entity, array case): Handle case of pragma Pack and component
10852 size attributre clause for same array.

11383 reorganization and documentation update for the case of predefined
11384 library generics (for which we do not reference an Afile).

11480 (Set_Item): When the new item is an element of the currently allocated
11481 table passed by reference, save a copy on the stack if we're going
11482 to reallocate. Also, in Table.Set_Item, make sure we test the proper
11483 variable to determine whether to call Set_Last.

11496 Thomas Quinot <quinot@adacore.com>
11498 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11499 derived type with interface progenitors use the analyzed formal as the
11500 parent of the actual, to create renamings for all the inherited
11501 operations in Derive_Subprograms.
11502 (Collect_Previous_Instances): new procedure within of
11503 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11504 unit being loaded, to ensure that the generation of global symbols is
11505 consistent in different compilation modes.
11506 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11507 takes progenitor types into account.
11508 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11509 traversing over the primitives of the formal and actual types to locate
11510 any abstract subprograms of the actual type that correspond to a
11511 nonabstract subprogram of the formal type's ancestor type(s), and issue
11512 an error if such is found.
11513 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11514 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11515 Remove bogus guard around calls to Inherit_Context.
11516 (Reset_Entity): If the entity is the selector of a selected component
11517 that denotes a named number, propagate constant-folding to the generic
11518 template only if the named number is global to the generic unit.
11519 (Set_Instance_Env): Only reset the compilation switches when compiling
11520 a predefined or internal unit.
11522 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11524 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
11525 parameter to determine whether operation applies to the prefix.
11526 (Complete_Object_Operation): If actual has an access type and
11527 controlling formal is not an in_parameter, reject the actual if it is
11528 an access_to_constant type.
11529 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11530 type, the candidate operations are found in the scope of declaration of
11531 the type, because the type has no primitive subprograms.
11532 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11533 a private extension, only examine visible components before trying to
11534 analyze as a prefixed call.
11535 Change Entity_List to Type_To_Use, for better readability.
11536 (Has_Fixed_Op): Use base type when checking whether the type of an
11537 operator has a user-defined multiplication/division
11538 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
11539 user-defined operators are available for fixed-point types.

11542 Ed Schonberg <schonberg@adacore.com>
11544 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
11545 formal At_Any_Place indicating, when True, that we want to test for
11546 availability of the stream attribute at any place (as opposed to the
11547 current visibility context only).
11548 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11549 purpose of enforcing E.2.2(8) only if it is not available at any place.
11550 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11551 when checking the legality of an extension aggregate in a preelaborable
11552 package. Treat the literal null as a valid default expression in a
11553 component declaration for a type with preelaborable initialization.
11554 A limited interface is a legal progenitor for the designated type of a
11555 remote access to class-wide type.

11563 (Find_Direct_Name): Add comment about Generate_Reference incorrectly
11564 setting the Referenced_As_LHS flag for entities that are implicitly
11566 (Find_Type): If the type is an internally generated incomplete type,
11567 mark the full view as referenced, to prevent spurious warnings.
11568 (Find_Selected_Component, Has_Components): Handle properly non-limited
11569 views that are themselves incomplete types.
11570 Handle interfaces visible through limited-with clauses.
11571 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11572 subprogram generic actual for which we have generated a renaming.
11573 Warn when the renaming introduces a homonym of
11574 the renamed entity, and the renamed entity is directly visible.

11577 Hristian Kirtchev <kirtchev@adacore.com>
11579 * sem_res.adb (Resolve_Allocator): Propagate any coextensions that
11580 appear in the subtree to the current allocator if it is not a static
11582 (Resolve_Allocator): Perform cleanup if resolution has determined that
11583 the allocator is not a coextension.
11584 (Resolve): Skip an interpretation hidden by an abstract operator only
11585 when the type of the interpretation matches that of the context.
11586 (Resolve): When looping through all possible interpretations of a node,
11587 do not consider those that are hidden by abstract operators.
11588 (Resolve_Actuals): When verifying that an access to class-wide object
11589 is an actual for a controlling formal, ignore anonymous access to
11590 subprograms whose return type is an access to class_wide type.
11591 (Resolve_Slice): If the prefix of the slice is a selected component
11592 whose type depends on discriminants, build its actual subtype before
11593 applying range checks on the bounds of the slice.
11594 (Valid_Conversion): In an instance or inlined body, compare root types,
11595 to prevent anomalies between private and public views.
11596 (Resolve): Improve error message for ambiguous fixed multiplication
11597 expressions that involve universal_fixed multiplying operations.

11617 elabration statements, register the package with the name server
11618 at the beginning, not at the end, of the elaboration statements so
11619 that they can create remote access to subprogram values that designate
11620 remote subprograms from the package.

12709 Zero_Formatting is set.
12710 Add case for CLI_Target.

12746 (Get_E_Length): Protect against bomb in case scope is standard

12748 an unconstrained array type, and the expression is a slice, use the
12749 bounds of the slice to construct the required constraint checks.
12750 Improve NOT NULL error messages
12751 (Apply_Constraint_Check): If the context is a null-excluding access
12752 type, diagnose properly the literal null.

12768 Arnaud Charlet <charlet@adacore.com>
12770 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12771 applicable to types that have the With_Type flag set. Returns the
12772 non-limited view of the type, if available, otherwise the type itself.
12773 For class-wide types, there is no direct link in the tree, so we have
12774 to retrieve the class-wide type of the non-limited view of the Etype.
12775 New attributes Static_Initialization and Static_Elaboration_Desired.
12776 Remove the pragma Thread_Body, and the associated flag
12777 Is_Thread_Body in entities, and all related code.
12778 (Suppress_Value_Tracking_On_Call): New flag

12790 (Original_Access_Type): Remove, not needed.
12791 (Root_Type): Handle properly subtypes of class-wide-types.
12794 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12795 class-wide types visible through limited-with clauses.
12796 (Try_Primitive_Operation): When examining all primitive operations of a
12797 tagged type, do not consider subprograms labeled as hidden unless they
12798 belong to a private generic type with a tagged parent.
12799 (Try_Object_Operation): Extensive rewriting, to handle properly various
12800 overloading cases, when several ancestors may have class-wide operations
12801 that are possible candidates, and when the overloaded functions return
12802 array types and have defaulted parameters so that the call may be
12803 interpreted as an indexing.
12804 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12805 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12806 successive actuals before analyzing the call itself.
12807 (Try_Primitive_Operation): A primitive operation is compatible with the
12808 prefix if the prefix has a synchronized type and the type of the formal
12809 is its corresponding record, as can be the case when the primitive
12810 operation is declared outside of the body of the type.
12811 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12812 perform homonym traversal, looking for class-wide operation matches
12813 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12814 access parameters are now restricted to anonymous access types.
12815 (Mark_Allocator): An allocator with a discriminant association parent is
12817 (Try_One_Prefix_Interpretation): If the type of the object is
12818 incomplete, as can be happen when it is a limited view obtained through
12819 a limited_with_clause, the selected component is not part of a prefixed
12821 (Complete_Object_Operation): Diagnose properly an object that is not
12822 aliased when the corresponding controlling formal is an access
12824 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12825 ambiguous calls in prefixed notation, where two primitives differ only
12826 in that the controlling argument of one is an access parameter.
12828 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12829 whether a function that returns an unconstrained type can be inlined.
12830 (Process_Formals): Diagnose properly the illegal use of an incomplete
12831 type in the profile of an access_to_subprogram declaration.
12832 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12833 operations are attached to the corresponding record.
12834 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12835 When processing a primitive of a concurrent type which implements an
12836 interface change the type of all controlling formals to that of the
12837 corresponding record type.
12838 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12839 to determine the tagged type to which a primitive belongs.
12840 (Check_Conventions): Capture condition to ignore a primitive operation
12841 (which is shared between the loop in Check_Conventions and the one in
12842 Check_Convention) in a new local function Skip_Check.
12843 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12844 confusion with Check_Conventions' own Prim_Op local variable.
12845 (Create_Extra_Formals): Test for a tagged result type rather than a
12846 controlling result when determining whether to add a BIP_Alloc_Form
12847 formal and a BIP_Final_List formal to the function.
12848 (Check_Conformance); For parameters that are anonymous access types,
12849 subtype conformance requires that the not null and the constant
12850 indicators must match
12851 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12852 to retrieve the appropriate type when processing a concurrent type
12853 declared within a generic. Minor comment reformatting. Change invocation
12854 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12856 (Analyze_Subprogram_Body): If the return type of a function is an
12857 anonymous access to the limited view of a class-wide type, and the
12858 non-limited view of the type is available, update the type of the
12859 function so that code can be generated.
12860 (Process_Formals): In case of access-subtype itype whose designated
12861 type is also an itype (situation that happens now with access to
12862 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12863 attribute to avoid backend problems.
12864 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12865 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12866 anonymous types' designated types are same before testing
12867 Subtypes_Statically_Match.
12868 (Create_Extra_Formals): Test for a named access parameter that is a
12869 controlling formal as an additional condition for adding an
12870 accessibility level formal. This can occur in the subp type created for
12871 dispatching calls in Expand_Dispatching_Call, and allows calling
12872 Create_Extra_Formals from that procedure rather than special-casing the
12873 extra formals there.
12874 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12875 when the function has a controlling result.
12876 (Check_Returns): Add much more knowledge of the optimization of local
12877 raise statements to gotos, to retain proper warnings in this case.
12878 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12879 nodes when looking for last statement.
12881 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12882 class-wide types visible through limited with clauses.
12883 (Add_One_Interp): If the operands are anonymous access types, the
12884 predefined operator on universal_access is immediately visibles
12885 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12886 other anonymous access types.
12887 (Disambiguate): Take into account CIL convention.
12888 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12890 2007-06-06 Robert Dewar <dewar@adacore.com>

12895 Fix lower bound of tables.
12898 * nlists.adb: Ditto.

12900 covers the range First_Node_Id - 1 up.
12902 2007-06-06 Javier Miranda <miranda@adacore.com>
12903 Ed Schonberg <schonberg@adacore.com>
12904 Bob Duff <duff@adacore.com>
12905 Hristian Kirtchev <kirtchev@adacore.com>
12907 * exp_aggr.ads, exp_aggr.adb:
12908 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12909 in extension aggregates.
12910 (Flatten): Other conditions being met, an aggregate is static if the
12911 low bound given by component associations is different from the low
12912 bound of the base index type.
12913 (Packed_Array_Aggregate_Handled): If the component type is itself a
12914 packed array or record, the front-end must expand into assignments.
12915 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12916 Init_Pr, instead of Ancestor_Is_Expression.
12917 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12918 coextension chain root, either generate a list controller or use the
12919 already existing one.
12920 (Static_Array_Aggregate): New procedure to construct a positional
12921 aggregate that can be handled by the backend, when all bounds and
12922 components are compile-time known constants.
12923 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12924 types covering interface types into assignments.
12925 (Replace_Type): move to Build_Record_Aggr_Code.
12926 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12927 interface type, convert to the definite type of the aggregate itself,
12928 so that needed components are visible.
12929 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12930 components and the context is an extended return statement do not
12931 create a transient block for it, to prevent premature finalization
12932 before the return is executed.
12933 (Gen_Assign): Do not generate a call to deep adjust routine if the
12934 component type is itself an array of controlled (sub)-components
12935 initialized with an inner aggregate.
12936 (Component_Check): New name for Static_Check. This name is now more
12937 appropriate, and documentation is added which was missing.
12938 (Component_Check): Add test for bit aligned component value
12939 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12940 Tagged_Comps, name is more appropriate given added function below.
12941 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

12945 Robert Dewar <dewar@adacore.com>
12947 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12948 Terminated: Add unchecked type conversion from System.Address to
12949 System.Tasking.Task_Id when calling the predefined primitive
12951 Disable new Ada 05 accessibility check for JVM.NET targets, which
12952 cannot be implemented in a practical way.
12953 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12954 the sources always references the tag of the actual object. Therefore,
12955 if 'Tag is applied in the sources to class-wide interface objects we
12956 generate code that displaces "this" to reference the base of the object.
12957 (Expand_N_Attribute_Reference, case Size): Return specified size if
12958 known to front end.
12959 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12960 has code that displaces the pointer of the object to manage interface
12961 types. However this code must not be executed when the prefix is a
12962 subprogram. This bug caused the wrong expansion of the internally
12963 generated assignment that fills the dispatch table when the primitive
12964 is a function returning a class-wide interface type.
12965 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12966 Set_Attribute_Name for Name_Unaligned_Valid.

12972 If the initialization is the equivalent aggregate of the initialization
12973 procedure of the type, do not remove it.
12974 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12975 initialized to null from having their expression reset to empty and
12976 note this exception in the comment.

12981 Gary Dismukes <dismukes@adacore.com>
12983 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
12984 Add "with" and "use" clauses for Sem_Attr.
12985 (Expand_Current_Value): Do not replace occurences of attribute
12986 references where the prefix must be a simple name.
12988 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
12989 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
12990 Attribute_Requires_Simple_Name_Prefix.
12991 (Name_Modifies_Prefix): Body of new function.
12992 (Requires_Simple_Name_Prefix): Body of new function.
12993 (Resolve_Attribute, case Access): Improve error message for case of
12994 mismatched conventions.
12995 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
12997 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12998 constrained subtype for a nominal unconstrained type, use its base type
12999 to check for conformance with the context.
13000 (Resolve_Attribute): Remove test of the access type being associated
13001 with a return statement from condition for performing accessibility
13002 checks on access attributes, since this case is now captured by
13003 Is_Local_Anonymous_Access.
13004 (Analyze_Access_Attribute): Set Address_Taken on entity
13005 (Analyze_Attribute, case Address): Set Address_Taken on entity
13006 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13007 validating an access attribute whose prefix is a current instance.
13008 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13009 applied to dispatching operations, if freezing is required then we set
13010 the attribute Has_Delayed_Freeze in the prefix's entity.
13011 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13012 current scope if access of local subprogram taken
13013 (Analyze_Access_Attribute): Check legality of self-reference even if the
13014 expression comes from source, as when a single component association in
13015 an aggregate has a box association.
13016 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13017 the prefix if it is a protected operation and the attribute is
13018 Unrestricted_Access.
13019 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13020 reference to the base type of the context, to force a constraint check
13021 when the context is an access subtype with an explicit constraint.
13022 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13023 node is rewritten as an interface conversion. leave unanalyzed after
13024 resolution, to ensure that type checking against the context will take

13028 Javier Miranda <miranda@adacore.com>
13029 Robert Dewar <dewar@adacore.com>
13031 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13032 wrapper when the full view of the controlling type of an inherited
13033 function that dispatches on result implements interfaces.
13034 (Expand_N_Object_Declaration): In cases where the type of the
13035 declaration is anonymous access, create finalization list for it.
13036 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13037 if the object has no explicit initialization, to match description of
13038 functionality of pragam Persistent_BSS.
13039 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13040 new function to build static aggregates, to replace initialization call
13041 when static initialization is desired.
13042 (Freeze_Type): Generate a list controller for an access type whenever
13043 its designated type has controlled anonymous access discriminants.
13044 (Build_Equivalent_Aggregate): New procedure to compute a static
13045 aggregate to be used as default initialization for composite types,
13046 instead of a generating a call to the initialization procedure for the
13048 (Build_Initialization_Call): When available, replace a call to the
13049 initialization procedure with a copy of the equivalent static aggregate
13051 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13052 declarations for objects of a class-wide interface type, rather than
13053 just identifiers, to prevent visibility problems.
13054 (Expand_N_Object_Declaration): When expanding the declaration for an
13055 object of a class-wide interface type, preserve the homonym chain of
13056 the original entity before exchanging it with that of the generated
13057 renaming declaration.
13058 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13059 active, because there is no way to handle the exception.
13060 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13061 to do a minimum decoration of the Access_Disp_Table list.
13062 (Expand_Record_Controller): Avoid the addition of the controller between
13063 the component containing the tag of a secondary dispatch table and its
13064 adjacent component that stores the offset to the base of the object.
13065 This latter component is only generated when the parent type has
13066 discriminants ---documented in Add_Interface_Tag_Components).
13067 (Apply_Array_Size_Check): Removed, no longer needed.
13068 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13069 components, create a Master_Entity for it only if it contains tasks.
13070 (Build_Init_Procedure): Suppress the tag assignment compiling under
13072 (Freeze_Record_Type): Remove code associated with creation of dispatch
13074 (Init_Secondary_Tags): Update type of actuals when generating calls to
13075 Ada.Tags.Set_Offset_To_Top
13076 (Stream_Operation_OK): Disable use of streams compiling under no
13078 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13079 if Has_Init_Expression set.
13080 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13081 Register_Primitive, which provides the same functionality.
13082 (Requires_Init_Proc): Return false in case of interface types.
13083 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13085 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13086 is always associated with a predefined primitive because the internal
13087 entities associated with interface types are not predefined primitives.
13088 Therefore, the call to Is_Internal is replaced by a call to the
13089 function Is_Predefined_Dispatching_Operation.
13090 (Make_Eq_If): When generating the list of comparisons for the
13091 components of a given variant, omit the controller component that is
13092 present if the variant has controlled components.

13095 Hristian Kirtchev <kirtchev@adacore.com>
13096 Bob Duff <duff@adacore.com>
13098 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13099 handle the creation of finalization lists and calls for nested
13100 coextensions when the root of the chains is part of a return statement.
13101 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13103 (Expand_Record_Equality): Skip components that are interface types.
13104 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13105 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13106 with Rewrite_Coextension. Change the condition for detecting coextension
13108 (Is_Local_Access_Discriminant): Removed.
13109 (Rewrite_Coextension): New routine which rewrites a static coextension
13110 as a temporary and uses its unrestricted access in the construction of
13112 (Complete_Coextension_Finalization): New routine. Generate finalization
13113 attachment calls to all delayed coextensions.
13114 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13115 the allocator is not a coextension itself and has delayed coextensions.
13116 If the current allocator is controlled, but also a coextension, delay
13117 the generation of the finalization attachment call.
13118 Rename local variable "Node" to "Nod" in order to avoid confusion with
13120 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13121 limited types that are not inherently limited. Such an allocator is
13122 illegal, but is generated by the expander for a return statement, to
13123 copy the result onto the secondary stack. This is the only case where a
13124 limited object can be copied. Generate code to displace the pointer
13125 to the object if the qualified expression is a class-wide interface
13126 object. Such displacement was missing and hence the copy of the object
13128 (Apply_Accessibility_Check): Handle allocated objects initialized in
13130 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13131 and Expand_Allocator_Expression. Allocating class-wide interface objects
13132 this routine displaces the pointer to the allocated object to reference
13133 the component referencing the corresponding secondary dispatch table.
13134 Expand_Allocator_Expression): Add missing support to allocate class-wide
13135 interface objects initialized with a qualified expression.
13136 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13137 function result type, and use the finalization list associated with the
13138 function scope in that case (such an anonymous type should not be
13139 treated like an access parameter's type).
13141 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13142 Gary Dismukes <dismukes@adacore.com>
13143 Javier Miranda <miranda@adacore.com>
13145 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13146 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13147 required exception handler.
13148 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13149 properly the case of a function whose return type is a limited
13150 class-wide interface type. Modify the code of the accessibility
13151 check to handle class-wide interface objects. In this case we need to
13152 displace "this" to reference the primary dispatch table to get access
13153 to the TSD of the object (to evaluate its accessibility level).
13154 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13155 rather than a controlling result as one of the conditions for
13156 generating tests of the implicit BIP_Alloc_Form formal. The
13157 initialization assignment is also handled according to whether the
13158 result is tagged instead of controlling.
13159 In the case where the init assignment is inserted in the "then" part of
13160 the allocation conditional, rewrite the target to be a dereference of
13161 the implicit BIP_Object_Access formal.
13162 If the returned value is unconstrained and created on the secondary
13163 stack, mark the enclosing block and function so that the secondary
13164 stack is not reclaimed on return.
13165 Treat returns from functions with controlling results similarly to
13166 returns from functions with unconstrained result subtypes.
13167 If the object returned is unconstrained, and an allocator must be
13168 created for it, analyze the allocator once the block for the extended
13169 return is installed, to ensure that finalizable components
13170 of the expression use the proper finalization list. Guard the call to
13171 Move_Final_List with a check that there is something to finalize.
13172 (Make_Tag_Ctrl_Assignment): Use "old" handling
13173 of controlled type assignment for virtual machines, since new code uses
13174 unsupported features (such as direct access to bytes in memory).
13176 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13177 Ed Schonberg <schonberg@adacore.com>
13179 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13180 accessibility actual, check for the case of an aliased object that has
13181 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13182 we fall into processing for the attribute rather than the name of the
13184 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13185 formal has its address taken in the body, create a temporary to capture
13186 value. If the return type is a limited interface, do not treat the
13187 return value as Controlled.
13188 (Is_In_Place_Function): If the return type is a limited interface,
13189 treat as returning in place. The actual returned object may not always
13190 be limited, but the caller has to assume that it is returned in place.
13191 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13192 context of an allocator, use the correct finalization chain (that is,
13193 the chain belonging to the access type, rather than the chain belonging
13194 to the current scope).
13195 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13196 result type rather than a controlling result as a precondition for
13197 adding an allocation form actual to a build-in-place call.
13198 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13199 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13200 primitive in the dispatch tables. This work is now done by Make_DT when
13201 the type is frozen.
13202 (Register_Predefined_DT_Entry): Removed.
13203 (Add_Return): If end label is not present, use sloc of last statement
13204 for generated return statement in procedure, for better gdb behavior
13206 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13207 object address nodes to ensure proper processing by routines like
13209 (Expand_Call): Fix generation of validity check for parameter
13210 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13211 the allocation form parameter if the result subtype is constrained,
13212 except when the function has a controlling result.
13213 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13214 rather than Is_Controlled and Has_Controlled_Component, since we want to
13215 include class-wide result types in this treatment. Also test for a
13216 controlling result, since that also requires passing a finalization
13218 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13219 even when the result subtype is constrained, to handle calls involving
13220 controlling results.
13221 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13222 is now called even when the result subtype is constrained, to handle
13223 calls involving controlling results.
13224 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13225 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13226 now performs the test).
13227 (Make_Build_In_Place_Call_In_Object_Declaration):
13228 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13229 constrained, to handle calls involving controlling results.
13230 (Add_Return): Accomodate rewritten pattern from local raise to goto
13231 transformation, so that we still recognize an transfer statement
13232 and do the right thing here in that case.
13233 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13234 and end of subprogram code.
13235 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13236 support for primitives that are functions (without formals) with a
13237 controlling result.
13238 (Inherited_From_Formal): If the actual subtype has not generic parent
13239 type, it is not an actual for a formal derived type, and there is no
13240 operation to inherit from the formal.
13242 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13243 Thomas Quinot <quinot@adacore.com>
13245 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13246 inserted cleanup code appropriately for GDB use.
13247 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13248 exception handler for Deep_Adjust or Deep_Finalize.
13249 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13250 Raise_From_Controlled_Operation is available, use a call to that
13251 subprogram instead of a plain "raise Program_Error" node to raise
13252 Program_Error if an exception is propagated from an Adjust or Finalize
13254 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13255 appears in the optional statement list of a triggering alternative, the
13256 scope actions can be inserted directly there, and not in the list that
13257 includes the asynchronous select itself.
13259 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13260 Robert Dewar <dewar@adacore.com>
13261 Hristian Kirtchev <kirtchev@adacore.com>
13263 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13264 generated exception handler appropriately when debugging generated code.
13265 Deal properly with No_Exception_Propagation restriction mode.
13266 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13267 System.Address to System.Tasking.Task_Id when processing the result of
13268 the predefined primitive _disp_get_task_id.
13269 (Expand_N_Asynchronous_Select): Clarify comment.
13270 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13271 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13272 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13273 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13274 privals and for generated call to Complete_Entry_Body, for better gdb
13276 (Copy_Result_Type): Utility to construct a parameter and result profile
13277 for protected functions whose return type is an anonymous access to
13279 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13281 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13282 point when the local-raise-to-goto transformation has taken place.
13284 2007-06-06 Javier Miranda <miranda@adacore.com>
13285 Nicolas Setton <setton@adacore.com>
13287 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13288 functionality when the backend is generating code.
13289 Otherwise any serious error
13290 reported by the backend calling the frontend routine Error_Msg
13291 changes the Compilation_Mode to Check_Semantics, disables the
13292 functionality of this routine and causes the generation of
13293 spureous additional errors.
13295 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13296 debugging information now generated by the compiler for fat-pointer
13298 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13300 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13302 2007-06-06 Thomas Quinot <quinot@adacore.com>
13304 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13305 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13306 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13307 For a remote call to a function with a classwide return type, apply an
13308 E.4(18) check to the returned value.
13309 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13310 stream attributes of the designated type of an RACW, as they are not
13311 dispatching primitive operations.
13313 2007-06-06 Geert Bosch <bosch@adacore.com>
13315 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a

13319 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13320 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13322 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13324 2007-06-06 Javier Miranda <miranda@adacore.com>
13326 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13327 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13329 2007-06-06 Javier Miranda <miranda@adacore.com>
13331 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13332 deallocation of class-wide interface objects.
13333 (Expand_Dispatching_Constructor_Call): Take into account that if the
13334 result of the dispatching constructor is an interface type, the
13335 function returns a class-wide interface type; otherwise the returned
13336 object would be actual. The frontend previously accepted returning
13337 interface types because Expand_Interface_Actuals silently performed
13338 the management of the returned type "as if" it were a class-wide
13340 (Expand_Dispatching_Constructor_Call): Replace call to
13341 Make_DT_Access_Action by direct call to Make_Function_Call.
13343 2007-06-06 Robert Dewar <dewar@adacore.com>
13344 Ed Schonberg <schonberg@adacore.com>
13346 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13347 compute masking constant, since we now set Esize properly to the
13349 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13350 to match the alignment.
13351 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13352 packed arrays of 8 bits or less.
13354 * freeze.adb (Freeze_Entity): When freezing the formals of a
13355 subprogram, freeze the designated type of a parameter of an access type
13356 only if it is an access parameter.
13357 Increase size of C convention enumeration object
13358 (Freeze_Entity, array type case): Make sure Esize value is properly
13359 adjusted for the alignment if it is known.
13360 (Freeze_Entity, array type case): When checking bit packed arrays for
13361 the size being incorrect, check RM_Size, not Esize.
13362 (Freeze_Record_Type): Check for bad discriminated record convention
13363 (In_Exp_Body): Return true if the body is generated for a subprogram
13364 renaming, either an attribute renaming or a renaming as body.
13365 (Check_Itype): If the designated type of an anonymous access component
13366 is a non-protected subprogram type, indicate that it is frozen, to
13367 prevent out-of-scope freeze node at some subsequent call.
13368 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13369 only if the subprogram is neither imported nor exported, as well as the
13370 NCA descriptor class if the subprogram is exported.

13375 Gary Dismukes <dismukes@adacore.com>
13377 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13378 default initialization on an imported object, when there is no
13379 initialization call generated for it.
13380 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13383 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13384 Static_Elaboration_Desired.
13385 Remove pragma Thread_Body.
13386 Implement a new pragma No_Body
13387 Removes the Explicit_Overriding pragma
13388 Remove Optional_Overriding pragma
13389 (Prag): Deal with Universal_Aliasing.
13390 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13391 Pragma_CIL_Constructor): New names.
13393 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13394 uses the equivalent aggregate of a type must be treated as an implicit
13396 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13397 has none of the other categories.
13398 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13399 to apply Import to an object renaming declaration.
13401 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13402 from a C++ class should be declared as limited and that it will be
13403 considererd limited.
13404 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13405 should be declared as limited and that it will be considererd limited.
13406 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas

13433 subtype from the function call, as is done for private types.
13434 (Side_Effect_Free): An expression that is the renaming of an object or
13435 whose prefix is the renaming of a object, is not side-effect free

13550 defined in GNAT.IO, which might not be stdout
13551 (Is_Valid): Adjust comment to mention that a positive reply means that
13552 Header_Of may be used to retrieve the allocation header associated with

13960 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
13961 associated with dispatch tables is known at compile time.
13962 (Get_Value): If an association in a record aggregate has a box
13963 association, and the corresponding record component has a default
13964 expression, always copy the default expression, even when the

15233 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
15234 "abstract subprograms must be visible" message, whether or not the type
15235 is an interface; that is, remove the special case for interface types.

15262 Remove no longer used entities.
15264 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
15265 longer needed, because the full type is now limited, and therefore a

15304 "X'Unrestricted_Access = Y'Access" and so forth to match.
15305 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,

15312 attempt to derive from a synchronized tagged type.
15313 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
15314 type, inherit the class-wide type already created, because it may
15315 already have been used in a self-referential anonymous access component.
15316 (Mentions_T): Recognize self-referential anonymous access components
15317 that use (a subtype of) the class-wide type of the enclosing type.
15318 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15319 Derived_Type for Prev formal on call to
15320 Check_Anonymous_Access_Components rather than Empty.
15321 (Make_Incomplete_Type_Declaration): Add test for case where the type has

15403 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15404 when -gnatg is not specified.
15405 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15406 there is no need to generate always a record_definition_node in case
15407 of synchronized interface types.

15434 (Convert_Aggr_In_Allocator): If the allocator is for an access
15435 discriminant and the type is controlled. do not place on a finalization
15436 list at this point. The proper list will be determined from the

15456 parameter of the containing subprogram.
15457 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15458 under No_Dispatching_Calls restriction. During the semantic analysis
15459 we already notified such violation.
15460 (Tagged_Membership): Constant folding. There is no need to check
15461 the tag at run-time if the type of the right operand is non
15462 class-wide abstract.

15477 initialize most the TSD components by means of an aggregate.
15478 Modify the declaration of the object containing the TSD
15479 because we now expand code that has a higher level of abstraction.
15480 The TSD has a discriminant containing the Inheritance Depth Level,
15481 value that is used in the membership test but also to fix the size
15482 of the table of ancestors.
15483 (Expand_Interface_Conversion): Insert function body at the closest place
15484 to the conversion expression, to prevent access-before-elaboration

15541 support concurrent types implementing interfaces.
15542 (Find_Implemented_Interface): Removed. All the calls to this subprogram

15546 CW_Or_Controlled_Type whenever the issue is related to
15547 using or not the secondary stack.

15587 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15588 a protected version of an operation declared in the private part of
15589 a protected object, because they may be invoked through a callback.

15645 after executing the request as it is more efficient
15646 than Copy_Any_Value.
15647 * Build the any containing Extra Formals with the
15648 appropriate typecode.
15649 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15650 empty Component_List.
15651 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15652 the tree the declaration for an object that serves as actual parameter
15653 in server-side stubs.
15654 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15655 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
15656 Use Build_Actual_Object_Declaration to prepare the actuals.

15663 function with the first not implicit parent type.
15664 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15665 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15666 typecode from the Etype. Therefore we retrieve the correct typecode
15667 with a call to Get_Any_Type.
15668 (Copy_Specification): Do controlling formal type substitution based on
15669 Is_Controlling_Formal flag, instead of caller-provided object type.
15670 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15671 a RACW primitive operation, we might get a subprogram declaration for an
15672 ancestor of the RACW designated type (not for the designated type
15673 itself), in the case where this operation is inherited. In this case we
15674 have no easy means of determining the original tagged type for which
15675 the primitive was declared, so instead we now rely on
15676 Copy_Specification to use the Is_Controlling_Formal flag to determine
15677 which formals require type substitution.

15686 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15687 run-time subprogram CW_Membership by call to Build_CW_Membership.
15688 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15689 by a function call, a temporary must be created before expanding the
15690 Constructor_Call itself, to prevent out-of-order elaboration in the
15691 back-end when stack checking is enabled..
15693 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15695 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15696 result are the bounds of the left operand, not the right.

16117 Gary Dismukes <dismukes@adacore.com>
16119 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16120 when capturing size information, instead of base type, which for a
16121 formal array type will be the unconstrained type.
16122 (Analyze_Formal_Object_Declaration): Add check for illegal default
16123 expressions for a formal in object of a limited type.
16124 (Instantiate_Object): Ditto.
16125 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16126 because they were defaulted in the formal package and no check applies
16128 (Check_Formal_Package_Instance): Extend conformance check to other
16129 discrete types beyond Integer.
16130 (Process_Default): Copy directly the unmatched formal. A generic copy
16131 has already been performed in Analyze_Formal_Package.
16132 (Analyze_Associations): If a formal subprogram has no match, check for
16133 partial parametrization before looking for a default, to prevent
16135 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16136 not set the instantiation environment before analyzing the actuals.
16137 Fixes regression on 8515-003 with implementation of AI-133.
16138 Set_Instance_Env checks whether the generic unit is a predefined
16139 unit, in which case the instance must be analyzed with the latest Ada
16140 mode. This setting must take place after analysis of the actuals,
16141 because the actuals must be analyzed and frozen in the Ada mode extant
16142 outside of the current instantiation.
16143 (Save_Env, Restore_Env): Preserve and restore the configuration
16144 parameters so that predefined units can be compiled in the proper Ada
16146 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16147 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16148 and Is_Abstract_Type.
16149 (Analyze_Formal_Package): For better error recovery, Add exception
16150 handler to catch Instantion_Error, which can be raised in
16151 Analyze_Associations

16154 Bob Duff <duff@adacore.com>
16155 Gary Dismukes <dismukes@adacore.com>
16157 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16158 prefix type is a discriminated subtype of the type of the formal.
16159 (Analyze_Allocator): Collect all coextensions regardless of the context.
16160 Whether they can be allocated statically is determined in exp_ch4.
16161 (Analyze_Selected_Component): If the prefix is a limited view and the
16162 non-limited view is available, use the non-limited one.
16163 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16164 therefore illegal), suggest a qualified expression rather than a type
16165 conversion, because a type conversion would be illegal in this context.
16166 (Anayze_Allocator): Trace recursively all nested allocators so that all
16167 coextensions are on the corresponding list for the root. Do no mark
16168 coextensions if the root allocator is within a declaration for a stack-
16169 allocated object, because the access discriminants will be allocated on
16171 (Analyze_Call): Remove restriction on calls to limited functions for the
16172 cases of generic actuals for formal objects, defaults for formal objects
16173 and defaults for record components.
16174 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16175 element list. Their expansion is delayed until the enclosing allocator
16176 is processed and its finalization list constructed.
16177 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16178 for an operation with the given name among the primitive operations of
16179 the corresponding record type.
16180 (Analyze_Selected_Component): If the prefix is a task type that
16181 implements an interface, and there is no entry with the given name,
16182 check whether there is another primitive operation (e.g. a function)
16184 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16185 properly the indexing of a function call written in prefix form, where
16186 the function returns an array type, and all parameters of the function
16187 except the first have defaults.
16188 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16189 the original operands, rather than relocating them, for efficiency and
16190 to work properly when an operand is overloaded.
16191 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16192 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16193 (Analyze_Selected_Component): If the prefix is a private extension, only
16194 scan the visible components, not those of the full view.
16195 (Try_Primitive_Operation): If the operation is a procedure, collect all
16196 possible interpretations, as for a function, because in the presence of
16197 classwide parameters several primitive operations of the type can match
16198 the given arguments.
16200 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16201 Robert Dewar <dewar@adacore.com>
16203 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16204 tag-indeterminate call to an abstract function, when the left-hand side
16206 (Analyze_Loop_Statement): Improve detection of infinite loops
16208 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16209 Thomas Quinot <quinot@adacore.com>
16211 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16212 out of Analyze_Package_Declaration, because processing must be applied
16213 to package bodies as well, for deferred constants completed by pragmas.
16214 (Analyze_Package_Declaration): When the package declaration being
16215 analyzed does not require an explicit body, call Check_Completion.
16216 (May_Need_Implicit_Body): An implicit body is required when a package
16217 spec contains the declaration of a remote access-to-classwide type.
16218 (Analyze_Package_Body): If the package contains RACWs, append the
16219 pending subprogram bodies generated by exp_dist at the end of the body.
16220 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16221 Is_Abstract_Subprogram and Is_Abstract_Type.
16222 (Preserve_Full_Attributes): The full entity list is not an attribute
16223 that must be preserved from full to partial view.
16225 * sem_dist.adb (Add_RAS_Dereference_TSS):
16226 Change primitive name to _Call so it cannot clash with any legal
16227 identifier, and be special-cased in Check_Completion.
16228 Mark the full view of the designated type for the RACW associated with
16229 a RAS as Comes_From_Source to get proper view switching when installing
16230 private declarations.
16231 Provite a placeholder nested package body along with the nested spec
16232 to have a place for Append_RACW_Bodies to generate the calling stubs
16233 and stream attributes.
16235 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16236 Robert Dewar <dewar@adacore.com>
16238 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16239 that is a limited view, check the non-limited view if available.
16240 (Undefined): Refine error message for missing with of Text_IO
16241 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16242 to distinguish real missing with cases.
16243 Fix format of all missing with messages
16244 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16245 renaming as body when renamed entity is abstract.
16247 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16248 Javier Miranda <miranda@adacore.com>
16250 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16251 predicate recursive, to handle complex expressions on literals whose
16252 spurious ambiguity comes from the abstract interpretation of some
16254 (Interface_Present_In_Ancestor): Add support to concurrent record
16256 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16257 Is_Abstract_Subprogram and Is_Abstract_Type.
16259 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16260 Javier Miranda <miranda@adacore.com>
16262 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16263 dereference of a local object R created as a reference to another
16264 object O, use the access level of O.
16265 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16266 rather than local Same_Formal_Type, to check whether protected operation
16267 overrides an inherited one.
16268 (Same_Formal_Type): New predicate, used when matching signatures of
16269 overriding synchronized operations, to handle the case when a formal
16270 has a type that is a generic actual.
16271 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16272 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16273 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16274 syntactic ambiguities involving indexing of function calls that return
16276 (Abstract_Interface_List): New subprogram that returns the list of
16277 abstract interfaces associated with a concurrent type or a
16278 concurrent record type.
16279 (Interface_Present_In_Parent): New subprogram used to check if a
16280 given type or some of its parents implement a given interface.
16281 (Collect_Abstract_Interfaces): Add support for concurrent types
16282 with interface types.
16283 (Has_Abstract_Interfaces): Add support for concurrent types with
16285 (Is_Parent): New subprogram that determines whether E1 is a parent
16286 of E2. For a concurrent type its parent is the first element of its
16287 list of interface types; for other types this function provides the
16288 same result than Is_Ancestor.
16289 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16290 (Collect_Synchronized_Interfaces): Removed because the subprogram
16291 Collect_Abstract_Interfaces provides this functionality.
16292 (Collect_Abstract_Interfaces): Minor update to give support to
16293 concurrent types and thus avoid undesired code duplication.
16294 (Get_Subprogram_Entity): Handle entry calls.
16295 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16297 (Enter_Name): Do not give -gnatwh hiding warning for record component
16298 entities, they never result in hiding.

16313 can be an E_Return_Statement.
16314 (Is_Coextension): New flag for allocators.

16333 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16334 expression with a COMPOUND_EXPR including the call instead of emitting
16335 the call directly here.
16336 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16337 high bound is constant and the slice is empty. Tidy.
16338 (tree_transform, case N_Op_Not): Handle properly the case where the
16339 operation applies to a private type whose full view is a modular type.
16340 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16341 Address_Clause, use the associated Expression as the GNAT tree
16342 representing the choice value to ensure the corresponding GCC tree is
16343 of the proper kind.
16344 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16345 instead of just the operands, as the base GCC stabilize_reference does.
16346 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16347 requested; otherwise fail.
16348 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16353 implementation of UI_Div.
16354 (UI_Div): Reimplement as a call to UI_Div_Rem.
16355 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16356 remainder, avoiding the cost of a multiplication and a subtraction.
16357 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
16358 provides both quotient and remainder in a single computation.
16359 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
16360 functions for uint.
16361 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram

16608 (mainly static expression evaluation).
16609 Reword some continuation messages
16610 Add some \\ sequences to continuation messages
16611 (Resolve_Call): Refine infinite recursion case. The test has been

16627 Valid_Conversion, to incorporate accessibility checks for arrays of
16628 anonymous access types.
16629 (Valid_Conversion): For a conversion to a numeric type occurring in an
16630 instance or inlined body, no need to check that the operand type is
16631 numeric, since this has been checked during analysis of the template.

17220 assignments where the target subtype is unconstrained and the target
17221 object is a parameter or dereference (other aliased cases are known

17442 then generate code to inherit the contents of the dispatch table
17443 directly from the ancestor.
17444 (Expand_Record_Controller): Insert controller component after tags of
17445 implemented interfaces.
17446 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17447 create null procedure overridings when null procedures are inherited
17449 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17450 declarations for overriding null primitives inherited from interfaces.
17451 (Is_Null_Interface_Procedure): New function in
17452 Make_Null_Procedure_Specs.
17453 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17454 immediate ancestor of a tagged type is an abstract interface type we
17455 must generate the specification of the predefined primitives associated
17456 with controlled types (because the dispatch table of the ancestor is
17457 null and hence these entries cannot be inherited). This is required to
17458 elaborate well the dispatch table.

17466 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
17468 (Expand_N_In): Do validity checks on range
17469 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17470 (Expand_N_Allocator): For "new T", if the object is constrained by
17471 discriminant defaults, allocate the right amount of memory, rather than
17472 the maximum for type T.
17473 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17474 when the allocator is initialized by a build-in-place call, since the
17475 allocator is already rewritten as a reference to the function result,
17476 and this prevents an unwanted duplication of the function call.
17477 Add with and use of Exp_Ch6.
17478 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17479 is a call to build-in-place function and apply
17480 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17481 untagged designated types).
17482 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17483 optimization if source or target is biased.
17484 (Expand_N_Allocator): Add comments for case of an allocator within a
17485 function that returns an anonymous access type designating tasks.
17486 (Expand_N_Allocator): apply discriminant checks for access
17487 discriminants of anonymous access types (AI-402, AI-416)

17490 Robert Dewar <dewar@adacore.com>
17491 Gary Dismukes <dismukes@adacore.com>
17492 Ed Schonberg <schonberg@adacore.com>
17494 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17496 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17497 (Expand_N_Assignment_Statement): Call
17498 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17499 build-in-place function call. Currently, this can happen only for
17500 assignments that come from aggregates.
17501 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17502 in order to alleviate the upward compatibility introduced by AI-318.
17503 (Expand_N_Extended_Return_Statement): Add support for handling the
17504 return object as a build-in-place result.
17505 (Expand_Non_Function_Return): Implement simple return statements nested
17506 within an extended return.
17507 (Enable_New_Return_Processing): Turn on the new processing of return
17509 (Expand_Non_Function_Return): For a return within an extended return,
17510 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17511 (Expand_N_Extended_Return_Statement): Implement AI-318
17512 (Expand_Simple_Function_Return): Ditto.
17513 (Expand_N_If_Statement): Handle new -gnatwt warning
17514 (Expand_N_Case_Statement): Handle new -gnatwt warning
17515 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17516 a protected object.
17517 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17518 validity checking of assignments to elementary record components.
17519 (Expand_N_Return_Statement): return Class Wide types on the secondary
17520 stack independantly of their controlled status since with HIE runtimes,
17521 class wide types are not potentially controlled anymore.
17523 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17526 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17527 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17528 it expects a block, procedure, or task. The return statement will get
17529 turned into a block, and Expand_Cleanup_Actions will happen then.

17532 Ed Schonberg <schonberg@adacore.com>
17533 Bob Duff <duff@adacore.com>
17534 Gary Dismukes <dismukes@adacore.com>
17536 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17538 (Expand_Inlined_Call): Tagged types are by-reference types, and
17539 therefore should be replaced by a renaming declaration in the expanded
17540 body, as is done for limited types.
17541 (Expand_Call): If this is a call to a function with dispatching access
17542 result, propagate tag from context.
17543 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17545 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17546 build-in-place when the right-hand side of an assignment is a
17547 build-in-place function call.
17548 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17549 of the explicit dereference of the allocator to the result subtype of
17550 the build-in-place function. This is needed to satisfy type checking
17551 in cases where the caller's return object is created by an allocator for
17552 a class-wide access type and the type named in the allocator is a
17554 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17555 conversion of the reference to the declared object to the result subtype
17556 of the build-in-place function. This is needed to satisfy type checking
17557 in cases where the declared object has a class-wide type. Also, in the
17558 class-wide case, change the type of the object entity to the specific
17559 result subtype of the function, to avoid passing a class-wide object
17560 without explicit initialization to the back end.
17561 (Register_Interface_DT_Entry): Moved outside the body of
17562 Freeze_Subprogram because this routine is now public; it is called from
17563 Check_Dispatching_Overriding to handle late overriding of abstract
17564 interface primitives.
17565 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17566 adding an implicit access actual on a call to a build-in-place function.
17567 (Expand_Actuals): Test for an actual parameter that is a call to a
17568 build-in-place function and apply
17569 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17570 (Is_Build_In_Place_Function): New function to determine whether an
17571 entity is a function whose calls should be handled as build-in-place.
17572 (Is_Build_In_Place_Function_Call): New function to determine whether an
17573 expression is a function call that should handled as build-in-place.
17574 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17575 calls to build-in-place functions as the initialization of an allocator.
17576 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17577 handling calls to build-in-place functions in contexts that do not
17578 involve init of a separate object (for example, actuals of subprogram
17580 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17581 handling calls to build-in-place functions as the initialization of an
17582 object declaration.
17583 (Detect_Infinite_Recursion): Add explicit parameter Process to
17584 instantiation of Traverse_Body to avoid unreferenced warning.
17585 (Check_Overriding_Inherited_Interfaces): Removed.
17586 (Register_Interface_DT_Entry): Code cleanup.
17587 (Register_Predefined_DT_Entry): Code cleanup.
17588 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17589 inlined statements if within a transient scope.
17590 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17591 formal parameters with occurrences of actuals in inlined body, establish
17592 visibility on the proper view of the actual's subtype for the body's
17594 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17595 compatibility mode and we have an imported CPP subprogram because
17596 for now we assume that imported CPP primitives correspond with
17597 objects whose constructor is in the CPP side (and therefore we
17598 don't need to generate code to register them in the dispatch table).
17599 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17600 aligned selected component.
17601 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17602 the actual of an in-mode parameter is a type conversion.
17603 (Expand_Actuals): If the call does not come from source and the actual
17604 is potentially misaligned, let gigi handle it rather than rejecting the
17605 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17606 Class Wide types as returning by reference independantly of their
17607 controlled status since with HIE runtimes class wide types are not
17608 potentially controlled anymore.
17610 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17612 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17613 references that are private components of the protected object.
17614 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
17615 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17616 instantiation to deal with warnings.

17618 System_Priority as its expected type, in case the expression has not
17621 2006-10-31 Robert Dewar <dewar@adacore.com>
17623 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17624 initialization of Homonym_Len.
17625 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17626 names from fully qualified name. Fixes problem of duplicate
17627 external names differing only in the presence of such a block name.
17629 2006-10-31 Thomas Quinot <quinot@adacore.com>
17630 Pablo Oliveira <oliveira@adacore.com>
17632 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17633 subprogram Ids, even if they are not yet assigned.
17634 (Build_Subprogram_Id): It is now this function that will take care of
17635 calling Assign_Subprogram_Ids if necessary.
17636 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17637 should be done only once they are assigned.
17638 (Build_From_Any_Function, case of tagged types): Add missing call to
17640 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17641 type for an RACW type.
17642 (Add_RACW_Features): When processing an RACW declaration for which the
17643 designated type is already frozen, enforce E.2.2(14) rules immediately.
17644 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17645 special reordering of controlling formals.
17647 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17648 associated stub type for an RACW type.
17650 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17652 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17653 fixed-point operations in an integer context, i.e. as operands of a
17654 conversion to an integer type, indicate that result must be rounded.
17656 2006-10-31 Robert Dewar <dewar@adacore.com>
17658 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17659 cases, pass the encoding method, since it is now required by the run
17662 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17663 assumption that Str'First = 1.
17664 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17665 it on to the Value_Wide_Wide_Character call.
17666 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17667 properly handles a string of the form quote-encoded_wide_char-quote.
17669 * s-wchcnv.adb: Minor reformatting
17671 2006-10-31 Javier Miranda <miranda@adacore.com>
17673 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17674 run-time membership test to ensure that the constructed object
17675 implements the target abstract interface.
17677 2006-10-31 Robert Dewar <dewar@adacore.com>
17679 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17680 Machine_Attribute pragma internally to implement the user pragma.
17681 Add processing for pragma Interface so that it is now completely
17682 equivalent to pragma Import.
17684 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17685 so that it can be applied to all entities, including record components
17686 and enumeration literals.
17687 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17688 priority ranges are correct, verify compatibility against task
17689 dispatching and locking policies, and if everything is correct an entry
17690 is added to the table containing priority specific dispatching entries
17691 for this compilation unit.
17692 (Delay_Config_Pragma_Analyze): Delay processing
17693 Priority_Specific_Dispatching pragmas because when processing the
17694 pragma we need to access run-time data, such as the range of
17695 System.Any_Priority.
17696 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17697 Allow pragma Unreferenced as a context item
17698 Add pragma Preelaborable_Initialization
17699 (Analyze_Pragma, case Interface): Interface is extended so that it is
17700 now syntactically and semantically equivalent to Import.
17701 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17702 insertion characters.
17703 Add handling for Pragma_Wide_Character_Encoding
17704 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17705 never supercedes a real restriction, and that a real restriction
17706 always supercedes a warning.
17707 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17714 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17715 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17716 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17718 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17719 type of the function containing a return statement, because the
17720 Return_Type field was removed. We now use the Return_Applies_To field.
17722 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17723 (Build_Task_Image_Decl): If procedure is not called from an
17724 initialization procedure, indicate that function that builds task name
17725 uses the sec. stack. Otherwise the enclosing initialization procedure
17726 will carry the indication.
17727 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17728 N_Object_Declaration instead.
17729 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17730 conditional dead code killed, and change implementation accordingly.
17731 (Insert_Actions): Add N_Return_Object_Declaration case.
17732 Correct comment to mention N_Extension_Aggregate node.
17733 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17734 attempts to save information for global variables which cannot be
17736 (Get_Current_Value_Condition): Handle conditions the other way round
17737 (constant on left). Also handle right operand of AND and AND THEN
17738 (Set_Current_Value_Condition): Corresponding changes
17739 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17740 (Get_Current_Value_Condition): Handle simple boolean operands
17741 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17742 (Get_Current_Value_Condition): If the variable reference is within an
17743 if-statement, does not appear in the list of then_statments, and does
17744 not come from source, treat it as being at unknown location.
17745 (Get_Current_Value_Condition): Enhance to allow while statements to be
17746 processed as well as if statements.
17747 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17749 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17750 of loop. This is safe now that we fixed Kill_Current_Values.
17751 (OK_To_Do_Constant_Replacement): Check whether current scope is
17752 Standard, before examining outer scopes.
17754 2006-10-31 Vincent Celier <celier@adacore.com>
17756 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17757 When True, apply VMS treatment to children of packages A, G, I and S.
17760 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17762 2006-10-31 Robert Dewar <dewar@adacore.com>

17767 (Freeze_Entity): Add check for Preelaborable_Initialization
17769 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17771 * g-expect.adb: Add Warnings (Off) to prevent new warning
17773 * lib-xref.adb: Add handling of Last_Assignment field
17774 (Generate_Reference): Centralize handling of pragma Obsolescent here
17775 (Generate_Reference): Accept an implicit reference generated for a
17776 default in an instance.
17777 (Generate_Reference): Accept a reference for a node that is not in the
17778 main unit, if it is the generic body corresponding to an subprogram
17781 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17783 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17785 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17787 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17788 use clauses, to avoid messages on packages used to qualify, and also
17789 to avoid messages from obsolescent units.
17790 (Warn_On_Useless_Assignments): Don't generate messages for imported
17791 and exported variables.
17792 (Warn_On_Useless_Assignments): New procedure
17793 (Output_Obsolescent_Entity_Warnings): New procedure
17794 (Check_Code_Statement): New procedure
17796 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
17797 Change name Is_Ada_2005 to Is_Ada_2005_Only
17798 (Last_Assignment): New field for useless assignment warning
17800 2006-10-31 Olivier Hainque <hainque@adacore.com>
17802 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17803 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17805 2006-10-31 Bob Duff <duff@adacore.com>
17806 Robert Dewar <dewar@adacore.com>
17807 Ed Schonberg <schonberg@adacore.com>
17809 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17810 Ada 95 mode, because it violates the new rules for AI-318.
17812 * g-awk.ads: Use overloaded subprograms in every case where we used to
17813 have a default of Current_Session. This makes the code closer to be
17814 correct for both Ada 95 and 2005.
17816 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17817 code, relying on the fact that the compiler generates a warning
17818 instead of an error in -gnatg mode.
17820 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17821 E_Return_Statement entity kind.
17822 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17824 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17825 report an error if the reserved word abstract has been previously found.
17826 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17828 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17829 parenthesized range attribute usage
17830 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17832 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17833 in the syntax for extended_return_statement. This is not in the latest
17834 RM, but the ARG is expected to issue an AI allowing this.
17835 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17836 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17837 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17838 P_Return_Statement): Parse the new syntax for extended_return_statement.
17840 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17841 Output_End_Missing): Add error-recovery code for the new
17842 extended_return_statement syntax; that is, the new E_Return entry on
17845 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17846 limited to nonlimited, because otherwise we violate the new Ada 2005
17847 rules about returning limited types in function Create_AST_Handler in
17850 * sem.adb (Analyze): Add cases for new node kinds
17851 N_Extended_Return_Statement and N_Return_Object_Declaration.
17853 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17854 type is in the same category as type of context before applying check,
17855 to prevent anomalies in instantiations.
17856 (Resolve_Aggregate): Remove test for limited components in aggregates.
17857 It's unnecessary in Ada 95, because if it has limited components, then
17858 it must be limited. It's wrong in Ada 2005, because limited aggregates
17860 (Resolve_Record_Aggregate): Move check for limited types later, because
17861 OK_For_Limited_Init requires its argument to have been resolved.
17862 (Get_Value): When copying the component default expression for a
17863 defaulted association in an aggregate, use the sloc of the aggregate
17864 and not that of the original expression, to prevent spurious
17865 elaboration errors, when the expression includes function calls.
17866 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17867 were missing. We also didn't handle qualified expressions. Now also
17868 allow function calls. Use new common routine OK_For_Limited_Init.
17869 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17870 with space can upper case letter).
17872 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17873 Has_Static_Discriminants flag
17874 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17875 type with discriminants.
17876 (Process_Range_Expr_In_Decl): Do validity checks on range
17877 (Build_Discriminant_Constraints): Use updated form of
17878 Denotes_Discriminant.
17879 (Process_Subtype): If the subtype is a private subtype whose full view
17880 is a concurrent subtype, introduce an itype reference to prevent scope
17882 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17883 Record_Type_Declaration): The functionality of the subprograms
17884 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17885 is now performed by a single routine.
17886 (Build_Derived_Record_Type): If the type definition includes an explicit
17887 indication of limitedness, then the type must be marked as limited here
17888 to ensure that any access discriminants will not be treated as having
17889 a local anonymous access type.
17890 (Check_Abstract_Overriding): Issue a detailed error message when an
17891 abstract subprogram was not overridden due to incorrect mode of its
17893 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17894 synchronized private extension declarations. Verify that the ancestor is
17895 a limited or synchronized interface or in the generic case, the ancestor
17896 is a tagged limited type or synchronized interface and all progenitors
17897 are either limited or synchronized interfaces.
17898 Derived_Type_Declaration): Check for presence of private extension when
17899 dealing with synchronized formal derived types.
17900 Process_Full_View): Enchance the check done on the usage of "limited" by
17901 testing whether the private view is synchronized.
17902 Verify that a synchronized private view is completed by a protected or
17904 (OK_For_Limited_Init_In_05): New function.
17905 (Analyze_Object_Declaration): Move check for limited types later,
17906 because OK_For_Limited_Init requires its argument to have been resolved.
17907 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17908 in order to alleviate the upward compatibility introduced by AI-318.
17909 (Constrain_Corresponding_Record): If the constraint is for a component
17910 subtype, mark the itype as frozen, to avoid out-of-scope references to
17911 discriminants in the back-end.
17912 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17913 this subprogram against wrong sources.
17914 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17915 discriminant of limited type completed with a protected type, when the
17916 discriminant is used to constrain a private component of the type, and
17917 expansion is disabled.
17918 (Find_Type_Of_Object): Do not treat a return subtype that is an
17919 anonymous subtype as a local_anonymous_type, because its accessibility
17920 level is the return type of the enclosing function.
17921 (Check_Initialization): In -gnatg mode, turn the error "cannot
17922 initialize entities of limited type" into a warning.
17923 (OK_For_Limited_Init): Return true for generated nodes, since it
17924 sometimes violates the legality rules.
17925 (Make_Incomplete_Declaration): If the type for which an incomplete
17926 declaration is created happens to be the currently visible entity,
17927 preserve the homonym chain when removing it from visibility.
17928 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17929 inherited subprograms.
17930 (Access_Definition): If this is an access to function that is the return
17931 type of an access_to_function definition, context is a type declaration
17932 and the scope of the anonymous type is the current one.
17933 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17934 incomplete subtype to the set of private dependents of the original
17936 (Constrain_Discriminated_Type): Emit an error message whenever an
17937 incomplete subtype is being constrained.
17938 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17939 corresponding subtype of the full view of the original incomplete type.
17940 (Check_Incomplete): Properly detect invalid usage of incomplete types

17978 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17979 call it with -static-libgcc, as there are some platforms, such as
17980 Darwin, where one of these two switches is compulsory to link.
17982 2006-10-31 Vincent Celier <celier@adacore.com>
17984 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17985 instead of ADA_PROJECT_PATH, for the project path.

17989 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17990 names in the project path, as absolute paths may correspond to
17991 multi-valued VMS logical names.

18024 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18026 (Layout_Variant_Record): Retrieve the discriminants from the entity
18027 rather than from the type definition, because in the case of a full
18028 type for a private type we need to take the discriminants from the
18030 (Layout_Component_List): When applying the Max operator to variants with
18031 a nonstatic size, check whether either operand is static and scale that
18032 operand from bits to storage units before applying Max.
18033 (Layout_Type): In VMS, if a C-convention access type has no explicit
18034 size clause (and does not inherit one in the case of a derived type),
18035 then the size is reset to 32 from 64.
18037 2006-10-31 Vincent Celier <celier@adacore.com>
18039 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18040 its file has already been loaded, according to the unit being loaded,
18041 not to the current value of Multiple_Unit_Index.
18043 2006-10-31 Thomas Quinot <quinot@adacore.com>
18044 Eric Botcazou <ebotcazou@adacore.com>

18079 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18081 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18082 Process_Body_Clauses): If the context of a body includes a use clause
18083 for P.Q then a with_clause for P in the same body is not redundant,
18084 even if the spec also has a with_clause on P.
18085 Add missing continuation mark to error msg
18086 (Build_Limited_Views): A limited view of a type is tagged if its
18087 declaration includes a record extension.
18088 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18089 node, even if the subunit has errors. This avoids malfunction by
18090 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18091 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18092 generation of obsolescent messages for with statements (cannot do
18093 this too early, or we cannot implement avoiding the messages in the
18094 case of obsolescent units withing obsolescent units).
18095 (Install_Siblings): If the with_clause is on a remote descendant of
18096 an ancestor of the current compilation unit, find whether there is
18097 a sibling child unit that is immediately visible.
18098 (Remove_Private_With_Clauses): New procedure, invoked after completing
18099 the analysis of the private part of a nested package, to remove from
18100 visibility the private with_clauses of the enclosing package

18103 now centralized in Generate_Reference.
18104 (Install_Limited_Context_Clauses): Remove superfluous error
18105 message associated with unlimited view visible through use
18106 and renamings. In addition, at the point in which the error
18107 is reported, we add the backslash to the text of the error
18108 to ensure that it is reported as a single error message.
18109 Use new // insertion for some continuation messages
18110 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18111 to create implicit with_clause for parent unit mentioned in original
18112 limited_with_clause.
18113 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18114 unit is a child unit. For ASIS queries.

18143 private extensions.
18144 (P_Type_Declaration): Add the new actual Abstract_Present to every call

18174 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18175 on VMS, change "__" to '.' before checking the name.

18179 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18180 dot, instead of replacing only the first '_'.
18182 * prj-part.adb (Parse): Convert project file path to canonical form
18184 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18185 extended, the project id of the project extending it is recorded in its

18194 Robert Dewar <dewar@adacore.com>
18196 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18197 only a restriction warning is active for the given restriction. This is
18198 desirable because we do not want to modify code in the case where only
18200 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18201 causes overriding of real restrictions.
18202 Take advantage of new No_Restrictions constant.
18204 * raise.h: (__gnat_set_globals): Change profile.
18206 2006-10-31 Arnaud Charlet <charlet@adacore.com>

18235 Generalizes previous mechanism to handle attribute references nested
18236 arbitrarily deep within the aggregate.
18237 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18238 can appear in an aggregate if this is a default-initialized aggregate
18239 for a self-referential type.

18253 a class-wide interface to a tagged type.
18254 Add support for the attribute Priority.
18255 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18256 whether the designated type is discriminated with a constrained partial
18257 view and require static matching in that case.
18258 Add local variable Des_Btyp. The Designated_Type
18259 of an access to incomplete subtype is either its non-limited view if
18260 coming from a limited with or its etype if regular incomplete subtype.
18262 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18263 Fix predicate to identify and allow cases of (expander-generated)
18264 references to tag of designated object of a RACW.
18265 (Validate_Static_Object_Name): In Ada 2005, a formal object is

18276 2006-10-31 Robert Dewar <dewar@adacore.com>
18278 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18279 useless assignments here and conditionalize it on absence of exception
18281 (Analyze_Exception_Handlers): Small code reorganization of error
18282 detection code, for new handling of formal packages.

18292 synchronized. Carry synchronized present over to the generated private
18294 (Validate_Derived_Type_Instance): Ensure that the actual of a
18295 synchronized formal derived type is a synchronized tagged type.
18296 (Instantiate_Formal_Package): When creating the instantiation used to
18297 validate the actual package of a formal declared without a box, check
18298 whether the formal itself depends on a prior actual.
18299 (Instantiate_Formal_Subprogram): Create new entities for the defining
18300 identifiers of the formals in the renaming declaration, for ASIS use.
18301 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18302 a renaming declaration or a subtype declaration for an actual in an
18303 instance, capture location information of declaration in generic, for
18305 (Instantiate_Formal_Package): Add comments on needed additional tests.
18306 AI-317 (partial parametrization) is fully implemented.
18307 (Validate_Private_Type_Instance): Add check for actual which
18308 must have preelaborable initialization
18309 Use new // insertion for some continuation messages
18310 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18311 Default_Expression. Add type retrieval when the declaration has an
18312 access definition. Update premature usage of incomplete type check.
18313 (Check_Access_Definition): New subsidiary routine. Check whether the
18314 current compilation version is Ada 05 and the supplied node has an
18316 (Instantiate object): Alphabetize local variables. Handle the creation
18317 of new renaming declarations with respect to the kind of definition
18318 used - either an access definition or a subtype mark. Guard against
18319 unnecessary error message in the context of anonymous access types after
18320 they have been resolved. Add check for required null exclusion in a
18321 formal object declaration.
18322 (Switch_View): A private subtype of a non-private type needs to be
18323 switched (the base type can have been switched without its private
18324 dependents because of the last branch of Check_Private_View.
18325 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18327 (Instantiate_Type): Emit an error message whenever a class-wide type of
18328 a tagged incomplete type is used as a generic actual.
18329 (Find_Actual_Type): Extend routine to handle a component type in a child
18330 unit that is imported from a formal package in a parent.
18331 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18332 agree on constrainedness, rather than checking against ultimate ancestor
18333 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18334 generic body, for navigation purposes.

18339 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18341 (New_Stream_Subprogram): When processing an attribute definition clause
18342 for a stream-oriented subprogram, record an entity node occurring at
18343 the point of clause to use for checking the visibility of the clause,
18344 as defined by 8.3(23) as amended by AI-195.
18345 (New_Stream_Subprogram): New procedure, factoring behaviour from both

18352 Javier Miranda <miranda@adacore.com>
18353 Robert Dewar <dewar@adacore.com>
18355 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18356 generate the same errors compiling under -gnatc.
18357 (Try_Object_Operation): If no candidate interpretation succeeds, but
18358 there is at least one primitive operation with the right name, report
18359 error in call rather than on a malformed selected component.
18360 (Analyze_Selected_Component): If the prefix is an incomplete type from
18361 a limited view, and the full view is available, use the full view to
18362 determine whether this is a prefixed call to a primitive operation.
18363 (Operator_Check): Verify that a candidate interpretation is a binary
18364 operation before checking the type of its second formal.
18365 (Analyze_Call): Add additional warnings for function call contexts not
18367 (Analyze_Allocator): Move the check for "initialization not allowed for
18368 limited types" after analyzing the expression. This is necessary,
18369 because OK_For_Limited_Init looks at the structure of the expression.
18370 Before analysis, we don't necessarily know what sort of expression it
18371 is. For example, we don't know whether F(X) is a function call or an
18372 indexed component; the former is legal in Ada 2005; the latter is not.
18373 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18374 were missing. We also didn't handle qualified expressions. Now also
18375 allow function calls. Use new common routine OK_For_Limited_Init.
18376 (Analyze_Type_Conversion): Do not perform some legality checks in an
18377 instance, because the error message will be redundant or spurious.
18378 (Analyze_Overloaded_Selected_Component): Do not do style check when
18379 setting an entity, since we do not know it is the right entity yet.
18380 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18381 (Analyze_Overloaded_Selected_Component): Same change
18382 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18383 since regular incomplete subtypes are transformed into corresponding
18384 subtypes of their full views.
18385 (Complete_Object_Operation): Treat name of transformed subprogram call
18386 as coming from source, for browsing purposes.
18387 (Try_Primitive_Operation): If formal is an access parameter, compare
18388 with base type of object to determine whether it is a primitive
18390 (Operator_Check): If no interpretation of the operator matches, check
18391 whether a use clause on any candidate might make the operation legal.
18392 (Try_Class_Wide_Operation): Check whether the first parameter is an
18393 access type whose designated type is class-wide.
18395 2006-10-31 Robert Dewar <dewar@adacore.com>
18396 Ed Schonberg <schonberg@adacore.com>
18397 Gary Dismukes <dismukes@adacore.com>
18399 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
18400 warn on infinite loops.
18401 Add \\ to some continuation messages
18402 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18403 (Process_Bounds): If the bounds are integer literals that result from
18404 constant-folding, and they carry a user-defined type, preserve that type
18405 rather than treating this as an integer range.
18406 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18407 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18408 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18409 left hand side of assignment.
18410 (Analyze_Assignment): Add suport to manage assigments to the attribute
18411 priority of a protected object.
18412 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18413 not just identifiers.
18414 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18415 or AND THEN for possible tracking.
18416 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18417 case of while loops so we can track values in the loop body.
18419 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18420 Hristian Kirtchev <kirtchev@adacore.com>
18421 Bob Duff <duff@adacore.com>
18423 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18424 procedure cannot be a protected operation (it is a basic_declaration,
18425 not a subprogram_declaration).
18426 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18427 Subp. Add logic for entry processing.
18428 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18429 Determine whether an entry or subprogram of a protected or task type
18430 override an inherited primitive of an implemented interface.
18431 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18432 Update the actual used in calls to Check_Overriding_Indicator.
18433 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18434 generate the proper reference to the parent unit, for cross-reference.
18435 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18437 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18438 (Add_Extra_Formal): Revise procedure to allow passing in associated
18439 entity, scope, and name suffix, and handle setting of the new
18440 Extra_Formals field.
18441 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18442 pass new parameters. Add support for adding the new extra access formal
18443 for functions whose calls are treated as build-in-place.
18444 (Analyze_A_Return_Statement): Correct casing in error message.
18445 Move Pop_Scope to after Analyze_Function_Return, because an extended
18446 return statement really is a full-fledged scope. Otherwise, visibility
18447 doesn't work right. Correct use of "\" for continuation messages.
18448 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18449 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18450 the node doesn't get properly marked as analyzed.
18451 (Analyze_Subprogram_Body): If subprogram is a function that returns
18452 an anonymous access type that denotes a task, build a Master Entity
18454 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18455 proper usage of null exclusion in a result definition.
18456 (Process_Formals): Code cleanup and new error message.
18457 (Process_Formals): Detect incorrect application of null exclusion to
18459 (Conforming_Types): Handle conformance between [sub]types and itypes
18460 generated for entities that have null exclusions applied to them.
18461 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18462 base type is an access subtype. This case arrises with null exclusions.
18463 (New_Overloaded_Entity): Do not remove the overriden entity from the
18464 homonym chain if it corresponds with an abstract interface primitive.
18465 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18466 call to the synthesized predicate Is_Incomplete_Type.
18467 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18469 (Analyze_Subprogram_Declaration): Check that abstract interface
18470 primitives are abstract or null.
18471 (Analyze_Subprogram_Specification): Remove previous check for abstract
18472 interfaces because it was not complete.
18473 (Has_Interface_Formals): Removed.
18475 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18476 Javier Miranda <miranda@adacore.com>
18478 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18479 of Analyze_Package_Body, to create Itype references for anonymous
18480 access types created in the package declaration, whose designated types
18481 may have only a limited view.
18482 (Analyze_Package_Specification): For the private part of a nested
18483 package, install private_with_clauses of enclosing compilation unit if
18484 we are in its visible part.
18485 (Declare_Inherited_Private_Subprograms): Complete barrier
18486 to ensure that the primitive operation has an alias to some parent
18487 primitive. This is now required because, after the changes done for the
18488 implementation of abstract interfaces, the contents of the list of
18489 primitives has entities whose alias attribute references entities of
18490 such list of primitives.
18491 (Analyze_Package_Specification): Simplify code that handles parent units
18492 of instances and formal packages.
18493 (Uninstall_Declarations): Check the convention consistency among
18494 primitive overriding operations of a tagged record type.
18496 2006-10-31 Robert Dewar <dewar@adacore.com>
18497 Hristian Kirtchev <kirtchev@adacore.com>
18498 Javier Miranda <miranda@adacore.com>
18499 Ed Schonberg <schonberg@adacore.com>
18501 * sem_ch8.adb: Minor error msg rewording
18502 (Undefined): When checking for misspellings, invert arguments (to get
18503 expected and found set right)
18504 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18505 (Analyze_Generic_Renaming): Same fix
18506 (Use_One_Package): Do not take into account the internal entities of
18507 abstract interfaces during the analysis of entities that are marked
18508 as potentially use-visible.
18509 (Find_Type): Handle the case of an attribute reference for
18510 implementation defined attribute Stub_Type (simply let the analysis of
18511 the attribute reference rewrite it).
18512 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18513 type that appears in a Use_Type clause.
18514 (Analyze_Object_Renaming): Add support for renaming of the Priority
18516 (Find_Type): In Ada 2005, a task type can be used within its own body,
18517 when it appears in an access definition.
18518 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18519 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18520 in a formal object declaration or in a subtype declaration.
18521 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18522 (Check_Null_Exclusion): New local routine to
18523 Analyze_Subprogram_Renaming. Check whether the formals and return
18524 profile of a renamed subprogram have required null exclusions when
18525 their counterparts of the renaming already impose them.
18526 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18527 Determine whether an entity is inside a generic scope.
18528 (In_Open_Scope): First pass of documentation update.
18529 (Find_Expanded_Name): Add support for shadow entities associated with
18530 limited withed packages. This is required to handle nested packages.
18531 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18532 that makes a renaming of a limited withed package illegal.
18534 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18535 Ed Schonberg <schonberg@adacore.com>
18537 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18538 Check_Overriding_Indicator.
18539 (Analyze_Task_Definition): Ditto.
18540 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18541 (Check_Overriding_Indicator): To find overridden interface operation,
18542 examine only homonyms that have an explicit subprogram declaration, not
18543 inherited operations created by an unrelated type derivation.
18544 (Check_Overriding_Indicator): When checking for the presence of "null"
18545 in a procedure, ensure that the queried node is a procedure
18547 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18548 type when the formal is an access to variable.
18549 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18550 (Analyze_Task_Type): Same addition
18551 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
18552 provide navigation capabilities for entries.
18554 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18555 Ed Schonberg <schonberg@adacore.com>
18556 Javier Miranda <miranda@adacore.com>
18557 Gary Dismukes <dismukes@adacore.com>
18559 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18560 inherited from an interface ancestor by another interface in the
18561 context of an instance as 'late'.
18562 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18563 of a call to a function that dispatches on access result.
18564 (Check_Dispatching_Operation): In case of late overriding of a primitive
18565 that covers abstract interface subprograms we register it in all the
18566 secondary dispatch tables associated with abstract interfaces.
18567 (Check_Dispatching_Call): Add check that a dispatching call is not made
18568 to a function with a controlling result of a limited type. This is a
18569 current implementation restriction.
18570 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18571 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18572 argument is an interface type that is a generic formal.
18573 (Is_Interface_Subprogram): Removed.
18574 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18575 operation, check the formals to handle the case in which it is
18576 associated with an abstract interface type.
18578 2006-10-31 Robert Dewar <dewar@adacore.com>
18579 Ed Schonberg <schonberg@adacore.com>

18588 * sem_eval.adb (Compile_Time_Compare): Make use of information from
18589 Current_Value in the conditional case, to evaluate additional
18590 comparisons at compile time.
18592 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18593 Hristian Kirtchev <kirtchev@adacore.com>
18594 Javier Miranda <miranda@adacore.com>
18596 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18597 subprogram type to provide better diagnostics in case of ambiguity.
18598 (Covers): Handle coverage of formal and actual anonymous access types in
18599 the context of generic instantiation.
18600 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18601 abstract interface types; this is required to handle concurrent types
18602 with discriminants and abstract interface types.
18603 (Covers): Include type coverage of both regular incomplete subtypes and
18604 incomplete subtypes of incomplete type visibles through a limited with
18607 2006-10-31 Robert Dewar <dewar@adacore.com>
18608 Hristian Kirtchev <kirtchev@adacore.com>
18609 Ed Schonberg <schonberg@adacore.com>

18616 Add missing continuation marks in error msgs
18617 (Unqualify): New function for removing zero or more levels of
18618 qualification from an expression. There are numerous places where this
18619 ought to be used, but we currently only deal properly with zero or one
18621 (In_Instance); The analysis of the actuals in the instantiation of a
18622 child unit is not within an instantiation, even though the parent
18623 instance is on the scope stack.
18624 (Safe_To_Capture_Value): Exclude the case of variables that are
18626 (Check_Obsolescent): Removed
18627 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
18628 is an aliased view, even when rewritten as a reference to the target
18629 object in an assignment.
18630 (Get_Subprogram_Entity): New function
18631 (Known_To_Be_Assigned): New function
18632 (Type_Access_Level): Compute properly the access level of a return
18633 subtype that is an anonymous access type.

18639 has a null exclusion depending on its Nkind.
18640 Change Is_Lvalue to May_Be_Lvalue
18641 (May_Be_Lvalue): Extensive additional code to deal with subprogram
18642 arguments (IN parameters are not Lvalues, IN OUT parameters are).
18643 (Safe_To_Capture_Value): Extend functionality so it can be used for
18644 the current value condition case.
18645 (Has_Compatible_Alignment): New function
18646 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
18647 objects to handle the Ada 2005 case, where aliasedness no longer implies
18648 that the object is constrained. In particular, for dereferenced names,
18649 the designated object must be assumed to be unconstrained.
18650 (Kill_Current_Values): Properly deal with the case where we encounter
18651 a loop in the scope chain.
18652 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
18654 (Compile_Time_Constraint_Error): Improve error message in error case

18660 2006-10-31 Robert Dewar <dewar@adacore.com>
18662 * s-osinte-tru64.adb:
18663 Mark Asm statements Volatile to prevent warnings (seems a
18664 reasonable change anyway)
18667 * s-mastop-irix.adb: Add Volatile to Asm statements
18668 Suppresses warning, and seems appropriate in any case
18670 * s-osinte-vms.adb: Add Volatile to Asm statement
18672 * s-vaflop-vms-alpha.adb: Add Volatile to Asm statements
18674 * exp_code.ads, exp_code.adb (Asm_Input_Value): Note that Error can be

18684 Private_Extension_Declaration to the list of assertions.
18685 (Is_Entry_Barrier_Function): New flag
18686 (Has_Self_Reference): New flag on aggregates, to indicate that they
18687 contain a reference to the enclosing type, inserted through a default
18689 (Next_Rep_Item): Move from Node4 to Node5.
18690 (Entity): Add this field for N_Attribute_Definition_Clause.
18691 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
18692 (N_Return_Object_Declaration): Remove this node kind. We now use
18693 N_Object_Declaration instead.
18694 (Actual_Designated_Subtype): Move to a different place to make room in
18695 N_Extended_Return_Statement.
18696 (Procedure_To_Call): Move to a different place to make room in
18697 N_Extended_Return_Statement.
18698 (Return_Type): Removed this field to make room in return statements
18700 (Return_Statement_Entity): New field in return statements, in part to
18701 replace Return_Type, and in part to support the fact that return
18702 statements are now pushed on the scope stack during semantic analysis.
18703 (Return_Object_Declarations): New field to support extended return
18705 (N_Extended_Return_Statement): New node for extended_return_statement
18707 (N_Return_Object_Declaration): New node for part of
18708 extended_return_statement nonterminal. Needed because all the necessary
18709 fields won't fit in N_Extended_Return_Statement.
18710 Generic_associations now carry the Box_Present flag, to indicate a
18711 default for an actual in a partially parametrized formal package.
18713 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
18714 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma
18715 and for the new predefined dispatching policies: EDF_Across_Priorities,

18717 Introduce new name Stub_Type for implementation defined attribute.
18718 Add pragma Preelaborable_Initialization
18719 Add entry for Priority attribute.

18725 Robert Dewar <dewar@adacore.com>
18726 Bob Duff <duff@adacore.com>
18728 * sprint.adb (Sprint_Node_Actual, case Parameter_Specification): Do not
18729 print null exclusion twice in the case of an access definition,
18730 Implement new -gnatL switch
18731 Remove N_Return_Object_Declaration. We now use
18732 N_Object_Declaration instead. Implement the case for
18733 N_Extended_Return_Statement. Alphabetize the cases.
18734 Add cases for new nodes N_Extended_Return_Statement and
18735 N_Return_Object_Declaration. The code is not yet written.
18736 Update the output for N_Formal_Object_Declaration
18737 and N_Object_Renaming_Declaration.
18738 (Write_Itype): Account for the case of a modular integer subtype whose

18752 binder generated file.
18754 2006-10-31 Gary Dismukes <dismukes@adacore.com>
18756 * s-scaval.adb (Initialize): Add new Boolean flag AFloat that is set
18757 True when AAMP extended floating-point is in use (48-bit). Change type
18758 ByteLF to ByteLLF, add new array type ByteLF and condition the size of
18759 the two byte array types on AFloat. Change type of IV_Ilf overlay
18760 variable from Byte8 to ByteLF. Add appropriate initializations of
18761 floating-point overlays for AAMP cases.
18763 2006-10-31 Javier Miranda <miranda@adacore.com>
18765 * s-tpoben.ads, s-tpoben.adb, s-taprob.ads, s-taprob.adb
18766 (Get_Ceiling): New subprogram that returns
18767 the ceiling priority of the protected object.

18783 * widechar.adb (Is_Start_Of_Wide_Char): In case of brackets encoding,
18784 add more precise check for the character sequence that follows '[' to
18785 avoid possible confusion in case if '[' is the last character of a
18787 (Scan_Wide): Always allow brackets encoding
18789 2006-10-31 Olivier Hainque <hainque@adacore.com>
18791 * s-stchop.ads: make this unit preelaborate. This is desirable in
18792 general and made mandatory by the use of this unit by s-taprop which
18793 is itself preelaborate.
18795 * s-stchop-vxworks.adb (Set_Stack_Info, Task_Descriptor type): Add
18796 Td_Events component.

19357 instantiation, the corresponding entity is the related_instance of the
19358 wrapper package created for the instance.
19360 2006-02-17 Ed Schonberg <schonberg@adacore.com>
19362 * sem_ch12.adb (Analyze_Package_Instantiation): Inline_Now is false if
19363 the current instance is nested within another instance in a child unit.

19366 Ed Schonberg <schonberg@adacore.com>
19368 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
19369 type we cannot inherit the primitive operations; we inherit the
19370 Corresponding_Record_Type (which has the list of primitive operations).
19371 (Check_Anonymous_Access_Types): When creating anonymous access types for
19372 access components, use Rewrite in order to preserve the tree structure,
19374 (Analyze_Object_Declaration): For limited types with access
19375 discriminants with defaults initialized by an aggregate, obtain
19376 subtype from aggregate as for other mutable types.
19377 (Derived_Type_Declaration): If the derived type is a limited interface,
19378 set the corresponding flag (Is_Limited_Record is not sufficient).

19382 * sem_ch6.adb (Build_Body_To_Inline): Enforce the rule that in order
19383 to inline a function that returns an unconstrained type, the return
19384 expression must be the first variable declared in the body of the
19387 2006-02-17 Javier Miranda <miranda@adacore.com>
19389 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
19390 abstract interface type, the static analysis is not enough to know if
19391 the interface is implemented or not by the source tagged type. Hence
19392 we must pass the work to the expander to generate the required code to
19393 evaluate the conversion at run-time.
19394 (Resolve_Equality_Op): Do not apply previous
19395 transformation if expansion is disasbled, to prevent anomalies when
19396 locating global references in a generic unit.

19430 this to ["5B"] and the new comments say why not.
19433 Add note for -gnatVo that this now includes the cases of type
19434 conversions and qualified expressions.

19576 table to take advantage of the 16 priority levels available on Windows
19577 2000 and XP. On NT4 there are only 7 priority levels, this is properly
19578 supported by this new mapping.

19624 (Read): Change the implementation to support unicode characters. It is
19625 not possible to use strlen() on Windows as this version supports only
19626 standard ASCII characters. So the length of the directory entry is now
19627 returned from the imported __gnat_readdir routine.

19665 E_Floating_Point_Subtype>: Inherit alias set of what we are making a
19666 subtype of to ensure conflicts amongst all subtypes in a hierarchy,
19667 necessary since these are not different types and pointers may
19668 actually designate any subtype in this hierarchy.
19669 (gnat_to_gnu_entity, case E_Record_Type): Always make fields for
19670 discriminants but put them into record only if not Unchecked_Union;

19673 components before variants; don't set TYPE_UNCHECKED_UNION_P.

19675 Remove special case code for Unchecked_Union and instead use main code
19676 with small changes.
19679 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
19680 variable with the expression being built, only its inner field.

19690 substituted for a CONST_DECL.
19691 (tree_transform, case N_Aggregate): Remove code for UNION_TYPE and pass
19692 Etype to assoc_to_constructor.
19693 (assoc_to_constructor): New argument, GNAT_ENTITY; use it to ignore
19694 discriminants of Unchecked_Union.
19695 (TARGET_ABI_OPEN_VMS): Define to 0 if not defined, so that later uses
19696 don't need cluttering preprocessor directives.
19697 (establish_gnat_vms_condition_handler): New function. Establish the GNAT
19698 condition handler as current in the compiled function.
19699 (body_with_handlers_p): New function. Tell whether a given sequence of
19700 statements node is attached to a package or subprogram body and involves
19701 exception handlers possibly nested within inner block statements.
19702 (emit_sequence_entry_statements): New function, to emit special
19703 statements on entry of sequences when necessary. Establish GNAT
19704 condition handler in the proper cases for VMS.

19733 Add comments that this version is now used only by the compiler and
19734 other basic tools. The full version that includes the Ada 2005 stuff
19735 is in separate files a-except-2005.ads/adb. The reason is that we do
19736 not want to cause bootstrap problems with compilers not recognizing

20072 junk obsolete Immediate_Errors flag.
20073 (Tree_Read): Change the way of reading Tree_Version_String - now we

20154 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20155 renamed subprograms so that the front-end must replace the prefix

20164 (Freeze_Record_Type): Do not generate the tables associated with
20165 timed and conditional dispatching calls through synchronized
20166 interfaces if compiling under No_Dispatching_Calls restriction.
20167 When compiling for Ada 2005, for a nonabstract
20168 type with a null extension, call Make_Controlling_Function_Wrappers
20169 and insert the wrapper function declarations and bodies (the latter
20170 being appended as freeze actions).
20171 (Predefined_Primitive_Bodies): Do not generate the bodies of the

20173 dispatching calls through synchronized interfaces if we are

20177 (Make_Controlling_Function_Wrappers): New procedure.

20182 procedure spec and body of the Offset_To_Top function that is generated
20183 when the parent of a type with discriminants has secondary dispatch
20185 (Init_Secondary_Tags): Handle the case in which the parent of the type
20186 containing secondary dispatch tables has discriminants to generate the
20187 correct arguments to call Set_Offset_To_Top.

20190 * a-tags.ads, a-tags.adb: (Check_Index): Removed.

20192 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20193 the same functionality of Get_Prim_Op_Address but applied to predefined
20194 primitive operations because the pointers to the predefined primitives
20195 are now saved in a separate table.
20196 (Parent_Size): Modified to get access to the separate table of primitive
20197 operations or the parent type.
20198 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20199 functionality of Set_Prim_Op_Address but applied to predefined primitive
20201 (Set_Signature): New subprogram used to store the signature of a DT.
20202 (Displace): If the Offset_To_Top value is not static then call the
20203 function generated by the expander to get such value; otherwise use
20204 the value stored in the table of interfaces.
20205 (Offset_To_Top): The type of the actual has been changed to Address to
20206 give the correct support to tagged types with discriminants. In this
20207 case this value is stored just immediately after the tag field.
20208 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20209 offset_to_top value is static and hence pass this value to the run-time
20210 to store it in the table of interfaces, or else if this value is dynamic
20211 and then pass to the run-time the address of a function that is
20212 generated by the expander to provide this value for each object of the
20215 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20216 (Default_Prim_Op_Count): New entity

20228 in a subprogram are wrapped in a cleanup block, indicate that the
20229 subprogram contains an inner block with an exception handler.
20230 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20231 Adjust call is for a newly-allocated object. In that case we must not
20232 assume that the finalization list chain pointers are correct (since they
20233 come from a bit-for-bit copy of the original object's pointers) so if
20234 the attach level would otherwise be zero (no change), we set it to 4
20235 instead to cause the pointers to be reset to null.
20237 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20238 reset chain pointers to null.

20242 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20243 string, and the context requires a loop for the assignment (e.g.
20244 because the left-hand side is packed), generate a unique name for the
20245 temporary that holds the string, to prevent spurious name clashes.

20249 Robert Dewar <dewar@adacore.com>
20250 Gary Dismukes <dismukes@adacore.com>
20252 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20253 return unconstrained arrays.
20255 (Expand_Call): An indirect call through an access parameter of a
20256 protected operation is not a protected call.
20257 Add circuit to raise CE in Ada 2005 mode following call
20258 to Raise_Exception.
20259 (Register_DT_Entry): Do nothing if
20260 the run-time does not give support to abstract interfaces.
20261 (Freeze_Subprogram): In case of dispatching operations, do not generate
20262 code to register the operation in the dispatch table if the source
20263 is compiled with No_Dispatching_Calls.
20264 (Register_Predefined_DT_Entry): Generate code that calls the new
20265 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20266 Set_Prim_Op_Address.
20268 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20269 on array assignments if the right-hand side is a function call that has
20270 been inlined. Check is performed on the assignment in the block.
20271 (Process_Bounds): If bounds and range are overloaded, apply preference
20272 rule for root operations to disambiguate, and diagnose true ambiguity.
20273 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20274 a tag-indeterminate right-hand side even when Expander_Active is True.
20275 Needed to ensure that dispatching calls to T'Input are allowed and
20276 get the tag of the target class-wide object.
20278 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20279 an inherited primitive operation that already overrides several
20280 abstract interface primitives. For transitivity, the new entity must
20281 also override all the abstract interface primitives covered by the
20282 inherited overriden primitive.
20283 Emit warning if new entity differs from homograph in same scope only in
20284 that one has an access parameter and the other one has a parameter of
20285 a general access type with the same designated type, at the same
20286 position in the signature.
20287 (Make_Inequality_Operator): Use source locations of parameters and
20288 subtype marks from corresponding equality operator when creating the
20289 tree structure for the implicit declaration of "/=". This does not
20290 change anything in behaviour except that the decoration of the
20291 components of the subtree created for "/=" allows ASIS to get the
20292 string images of the corresponding identifiers.
20293 (Analyze_Return_Statement): Remove '!' in warning message.
20294 (Check_Statement_Sequence): Likewise.
20295 (Analyze_Subprogram_Body): For an access parameter whose designated type
20296 is an incomplete type imported through a limited_with clause, use the
20297 type of the corresponding formal in the body.
20298 (Check_Returns): Implicit return in No_Return procedure now raises
20299 Program_Error with a compile time warning, instead of beging illegal.
20300 (Has_Single_Return): Function returning unconstrained type cannot be
20301 inlined if expression in unique return statement is not an identifier.
20302 (Build_Body_To_Inline): It is possible to inline a function call that
20303 returns an unconstrained type if all return statements in the function
20304 return the same local variable. Subsidiary procedure Has_Single_Return
20305 verifies that the body conforms to this restriction.
20307 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20308 same type, and one of them is of an anonymous access type, convert
20309 the other operand to it, so that this is a valid binary operation for
20311 (Resolve_Type_Conversion): Handle subtypes of protected types and
20312 task types when accessing to the corresponding record type.
20313 (Resolve_Allocator): Add '\' in 2-line warning message.
20314 Remove '!' in warning message.
20315 (Resolve_Call): Add '\' in 2-line warning message.
20316 (Valid_Conversion): Likewise.
20317 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20318 resulting type may be an access type with an implicit dereference.
20319 Obtain the proper component from the designated type.
20320 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20321 given by an expanded name with prefix Standard, when the operands are
20322 of an anonymous access type.
20323 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20324 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20325 prefix of the expression is not of an incomplete type. Allows full
20326 diagnoses of all semantic errors.
20327 (Resolve_Actuals): If the actual is an allocator whose directly
20328 designated type is a class-wide interface we build an anonymous
20329 access type to use it as the type of the allocator. Later, when
20330 the subprogram call is expanded, if the interface has a secondary
20331 dispatch table the expander will add a type conversion to force
20332 the displacement of the pointer.
20333 (Resolve_Call): If a function that returns an unconstrained type is
20334 marked Inlined_Always and inlined, the call will be inlined and does
20335 not require the creation of a transient scope.
20336 (Check_Direct_Boolean_Op): Removed
20337 (Resolve_Comparison_Op): Remove call to above
20338 (Resolve_Equality_Op): Remove call to above
20339 (Resolve_Logical_Op): Inline above, since this is only call.
20340 (Valid_Conversion): Handle properly conversions between arrays of
20341 convertible anonymous access types.
20344 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20345 the literal in an unchecked conversion, because GCC 4.x needs a static
20346 value for a string bound.
20348 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20349 Hristian Kirtchev <kirtchev@adacore.com>
20351 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20352 components of the corresponding record, take into account component
20353 definitions that are access definitions.
20354 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20355 procedure is not considered a dispatching call and will be expanded
20358 2006-02-13 Javier Miranda <miranda@adacore.com>
20360 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20361 controlling argument of the dispatching call is an abstract interface
20362 class-wide type then we use it directly.
20363 Check No_Dispatching_Calls restriction.
20364 (Default_Prim_Op_Position): Remove the code that looks for the last
20365 entity in the list of aliased subprograms. This code was wrong in
20367 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20368 when the source is compiled with the No_Dispatching_Calls restriction.
20369 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20370 if we are compiling with restriction No_Dispatching_Calls.
20371 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20372 subprograms if we are compiling under No_Dispatching_Calls restriction.
20373 (Make_DT): Generate a dispatch table with a single dummy entry if
20374 we are compiling with the No_Dispatching_Calls restriction. In
20375 addition, in this case we don't generate code that calls to the
20376 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20377 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20378 of this subprogram if compiling with the No_Dispatching_Calls
20380 (Expand_Type_Conversion): Instead of using the actual parameter,
20381 the argument passed as parameter to the conversion function was
20382 erroneously referenced by the expander.
20383 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20384 Set_Predefined_Primitive_Op_Address and Set_Signature.
20385 (Expand_Dispatching_Call): Generate call to
20386 Get_Predefined_Prim_Op_Address for predefined primitives.
20387 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20388 predefined primitives.
20389 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20390 primitives we reserve one dummy entry to ensure that the tag does not
20391 point to some memory that is associated with some other object. In
20392 addition, remove all the old code that generated the assignments
20393 associated with the signature of the dispatch table and replace them
20394 by a call to the new subprogram Set_Signature.
20395 (Set_All_DT_Position): Change the algorithm because now we have a
20396 separate dispatch table associated with predefined primitive operations.
20397 (Expand_Interface_Conversion): In case of non-static offset_to_top
20398 add explicit dereference to get access to the object after the call
20399 to displace the pointer to the object.
20400 (Expand_Interface_Thunk): Modify the generation of the actual used
20401 in the calls to the run-time function Offset_To_Top to fulfil its
20403 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20405 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20407 * exp_dist.adb (Copy_Specification): For access parameters, copy
20408 Null_Exclusion flag, which will have been set for stream subprograms
20411 2006-02-13 Pascal Obry <obry@adacore.com>
20413 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20414 previous implementation was using the C runtime spawnve routine but
20415 the corresponding wait was using directly the Win32 API. This was
20416 causing some times a lock when waiting for an event using
20417 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20418 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20419 API fixes this problem.
20421 2006-02-13 Robert Dewar <dewar@adacore.com>
20423 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20431 array reference that is an explicit dereference, mark the converted
20432 (packed) array reference as analyzed to prevent a forthcoming
20433 reanalysis from resetting its type to the original (non-packed) array
20436 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20437 Javier Miranda <miranda@adacore.com>
20438 Eric Botcazou <ebotcazou@adacore.com>
20440 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20441 Is_Predefined_Primitive_Operation): When
20442 searching for the predefined equality operator, verify that operands
20443 have the same type.
20444 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20445 for the last entity in the list of aliased subprograms. This code
20446 was wrong in case of renamings.
20447 (Set_Renamed_Subprogram): New procedure
20448 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20449 Exp_Type constant computed when entering this subprogram.

20451 (OK_To_Do_Constant_Replacement): New function
20452 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20453 (Side_Effect_Free): An attribute reference 'Input is not free of
20454 side effect, unlike other attributes that are functions. (from code
20456 (Remove_Side_Effects): Expressions that involve packed arrays or records
20457 are copied at the point of reference, and therefore must be marked as
20458 renamings of objects.
20459 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20460 not a dispatching operation.
20463 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20464 elementary types in all cases.
20466 2006-02-13 Javier Miranda <miranda@adacore.com>
20468 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20469 task types when accessing to the corresponding record type.
20470 Remove '!' in warning message.
20472 2006-02-13 Olivier Hainque <hainque@adacore.com>
20474 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20475 to avoid useless and space inefficient overalignments on targets where
20476 Max_Alignment is larger than 16.
20478 2006-02-13 Pascal Obry <obry@adacore.com>
20480 * g-catiio.adb (Sec_Number): New type used to compute the number of
20481 seconds since 1-1-1970.
20482 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20483 negative numbers (years, months...) it is better to have a Natural here.
20485 (Image) [Number]: Change parameter from Long_Integer to Number.
20486 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20487 overflow for dates past year 2038.
20489 2006-02-13 Matthew Heaney <heaney@adacore.com>
20491 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20494 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20496 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20498 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20499 finalization can occur normally.
20501 2006-02-13 Vincent Celier <celier@adacore.com>
20503 * gnatcmd.adb (Rules_Switches): New table
20504 (Add_To_Rules_Switches): New procedure
20505 (GNATCmd): For command CHECK, put all options following "-rules" in the
20506 Rules_Switches table. Append these -rules switches after the -cargs
20509 2006-02-13 Robert Dewar <dewar@adacore.com>
20511 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20512 These two cases were generating incorrect output, and if this unit
20513 was built with checks on, generated a discriminant mismatch constraint
20516 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20517 Robert Dewar <dewar@adacore.com>
20519 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20520 view is an array type, indicate the component type as well, for
20521 navigation purposes.
20522 (Generate_Reference): Don't consider array ref on LHS to be a case
20523 of violating pragma Unreferenced.
20524 Do not give Ada 2005 warning except on real reference.
20526 2006-02-13 Vincent Celier <celier@adacore.com>
20528 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20529 main source, add switch -mdebug-main=_ada_ so that the executable can
20530 be debugged by the standard VMS debugger.
20531 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20532 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20533 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20534 of the last source, as the binding and linking phases are never
20536 Set all executable obsolete when rebuilding a library.
20538 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20541 2006-02-13 Javier Miranda <miranda@adacore.com>
20544 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20545 code to improve the error message reported when the program has
20546 declarations of abstract interface types and it is not compiled with
20547 the -gnat05 switch.
20548 (P_Access_Definition): Reorganize the code to improve the error
20549 message reported when the new Ada 2005 syntax for anonymous
20550 access types is used and the program is not compiled with the

20588 Call Recursive_Check with parameter When_No_Sources.
20589 (Recursive_Check): New parameter When_No_Sources. Call itself and
20590 Prj.Nmsc.Check with parameter When_No_Sources.
20591 (Process): New parameter When_No_Sources. Call Check with parameter
20593 (Copy_Package_Declarations): New procedure to copy renamed parameters

20601 * prj-makr.adb (Make): Preserve the comments from the original project
20603 When removing nodes (attributes Source_Dirs, Source_Files,
20604 Source_List_File and package Naming), save the comments and attach the
20605 saved comments to the newly created nodes.
20606 Do not add a with clause for the naming package if one already exists.

20618 (Check_Dispatching_Operation): Do not generate code to register the
20619 operation in the dispatch table if the source is compiled with
20620 restriction No_Dispatching_Calls.

20622 No_Return procedure with procedure that is not No_Return
20623 (Check_Dispatching_Call): Suppress the check for an abstract operation
20624 when the original node of an actual is a tag-indeterminate attribute
20625 call, since the attribute, which must be 'Input, can never be abstract.
20626 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20627 call to the Input attribute (even when rewritten).
20628 (Propagate_Tag): Augment comment to indicate the possibility of a call
20629 to an Input attribute.
20631 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20632 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
20634 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
20635 No_Wide_Characters is no longer partition-wide
20636 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
20639 2006-02-13 Douglas Rupp <rupp@adacore.com>
20641 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20643 2006-02-13 Javier Miranda <miranda@adacore.com>
20645 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20646 handles default-initialized components to keep separate the management
20647 of this feature but also avoid the unrequired resolution and
20648 expansion of components that do not have partially initialized
20650 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20651 (Check_Bounds): Likewise.
20652 (Check_Length): Likewise.
20654 2006-02-13 Javier Miranda <miranda@adacore.com>
20655 Ed Schonberg <schonberg@adacore.com>
20657 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20658 abstract interface type call analyze_and_resolve to expand the type
20659 conversion into the corresponding displacement of the
20660 reference to the base of the object.
20661 (Eval_Attribute, case Width): For systems where IEEE extended precision
20662 is supported, the maximum exponent occupies 4 decimal digits.
20663 (Accessibility_Message): Add '\' in 2-line warning message.
20664 (Resolve_Attribute): Likewise.
20665 (case Attribute_Access): Significantly revise checks
20666 for illegal access-to-subprogram Access attributes to properly enforce
20667 the rules of 3.10.2(32/2).
20668 Diagnose use of current instance with an illegal attribute.
20670 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20672 (Enclosing_Generic_Unit): New function to return a node's innermost
20673 enclosing generic declaration node.
20674 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20675 (Type_Access_Level): The accessibility level of anonymous acccess types
20676 associated with discriminants is that of the current instance of the
20677 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20678 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20679 (Kill_Current_Values_For_Entity): New function
20680 (Enter_Name): Change formal type to Entity_Id
20682 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20683 Ed Schonberg <schonberg@adacore.com>
20684 Gary Dismukes <dismukes@adacore.com>
20686 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20687 Analyze_Compilation_Unit.
20688 Detect and warn on redundant with clauses detected in a package spec
20689 and/or body when -gnatwr is used.
20690 (Analyze_Context): Analyze config pragmas before other items
20691 (Install_Context_Items): Don't analyze config pragmas here
20692 (Install_Limited_Withed_Unit): Set limited entity of package in
20693 with_clause so that cross-reference information or warning messages on
20694 unused packages can be properly generated
20695 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20696 has Error_Posted set. Prevent infinite loops in illegal programs.
20697 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20698 to the point of the error test requiring the current unit to be private.
20699 This ensures that private with clauses are not exempted from the basic
20700 checking for being a descendant of the same library unit parent as a
20701 withed private descendant unit.
20702 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20703 handle private with clauses properly, as well as to account for cases
20704 where the withed unit is a public descendant of a private ancestor
20705 (in which case the current unit must be a descendant of the private
20706 ancestor's parent). The spec comments were updated accordingly. Also,
20707 the old error message in this subprogram was replaced with error
20708 messages that mirror the errors tested and reported by
20709 Check_Private_Child_Unit.
20710 Parameter and variable names improved for readability.
20711 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20712 private as the precondition for calling
20713 Check_Private_Limited_Withed_Unit since that subprogram has been
20714 revised to test public units as well as private units.

20718 Ed Schonberg <schonberg@adacore.com>
20719 Javier Miranda <miranda@adacore.com>
20721 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20722 that Scope_Stack.First = 1.
20723 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20724 were not always properly handled previously.
20725 (Formal_Entity): Complete rewrite, to handle properly some complex case
20726 with multiple levels of parametrization by formal packages.
20727 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20728 to the corresponding derived type declaration for proper semantics.
20730 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20731 (Check_Component): Enforce restriction on components of
20732 unchecked_unions: a component in a variant cannot contain tasks or
20734 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20736 Add pragma Ada_2005 (synonym for Ada_05)
20737 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20738 were not always properly handled previously.
20739 Document that pragma Propagate_Exceptions has no effect
20740 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20741 (Set_Convention_From_Pragma): Check that if a convention is
20742 specified for a dispatching operation, then it must be
20743 consistent with the existing convention for the operation.
20744 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20745 longer required to specify an vtable-ptr component in the record. For
20746 compatibility reasons we leave the support for the previous definition.
20747 (Analyze_Pragma, case No_Return): Allow multiple arguments
20749 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20750 non-overrideen inherited operation with a controlling result as
20751 illegal only its implicit declaration comes from the derived type
20752 declaration of its result's type.
20753 (Check_Possible_Deferred_Completion): Relocate the object definition
20754 node of the subtype indication of a deferred constant completion rather
20755 than directly analyzing it. The analysis of the generated subtype will
20756 correctly decorate the GNAT tree.
20757 (Record_Type_Declaration): Check whether this is a declaration for a
20758 limited derived record before analyzing components.
20759 (Analyze_Component_Declaration): Diagnose record types not explicitly
20760 declared limited when a component has a limited type.
20761 (Build_Derived_Record_Type): Code reorganization to check if some of
20762 the inherited subprograms of a tagged type cover interface primitives.
20763 This check was missing in case of a full-type associated with a private
20765 (Constant_Redeclaration): Check that the subtypes of the partial and the
20766 full view of a constrained deferred constant statically match.
20767 (Mentions_T): A reference to the current type in an anonymous access
20768 component declaration must be an entity name.
20769 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20770 class_wide type to refer to full type, not to the incomplete one.
20771 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20772 available. Required to give support to the certified run-time.
20773 (Analyze_Component_Declaration): In case of anonymous access components
20774 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20775 (Process_Discriminants): For an access discriminant, use the
20776 discriminant specification as the associated_node_for_itype, to
20777 simplify accessibility checks.
20779 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20780 Javier Miranda <miranda@adacore.com>
20782 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20783 abstract interpretations on an operator, remove interpretations that
20784 yield Address or a type derived from it, if one of the operands is an
20786 (Try_Object_Operation.Try_Primitive_Operation,
20787 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20788 location when creating the new reference to a primitive or class-wide
20789 operation as a part of rewriting a subprogram call.
20790 (Try_Primitive_Operations): If context requires a function, collect all
20791 interpretations after the first match, because there may be primitive
20792 operations of the same type with the same profile and different return
20793 types. From code reading.
20794 (Try_Primitive_Operation): Use the node kind to choose the proper
20795 operation when a function and a procedure have the same parameter
20797 (Complete_Object_Operation): If formal is an access parameter and prefix
20798 is an object, rewrite as an Access reference, to match signature of
20799 primitive operation.
20800 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20801 by an expanded name with prefix Standard, when the operands are of an
20802 anonymous access type.
20803 (Remove_Abstract_Operations): If the operation is abstract because it is
20804 inherited by a user-defined type derived from Address, remove it as
20805 well from the set of candidate interpretations of an overloaded node.
20806 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20809 2006-02-13 Bob Duff <duff@adacore.com>
20811 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20812 redundant use clauses.
20813 In particular, if the scope of two use clauses overlaps, but one is not
20814 entirely included in the other, we should not warn. This can happen
20815 with nested packages.
20816 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20817 reported errors. The bug was reported when the compiler was built
20818 with assertions enabled.
20819 (Find_Type): If the node is a 'Class reference and the prefix is a
20820 synchronized type without a corresponding record, return the type
20823 2006-02-13 Javier Miranda <miranda@adacore.com>
20825 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20826 if this is the full-declaration associated with a private declaration
20827 that implement interfaces, then the private type declaration must be
20829 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20830 as aliased. The use of the 'access attribute is not available for such
20831 object (for this purpose the object should be explicitly marked as
20832 aliased, but being an anonymous type this is not possible).
20834 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20835 Robert Dewar <dewar@adacore.com>
20837 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20838 compilation unit is an elaboration scope.
20839 (Add_Task_Proc): Add '\' in 2-line warning message.
20840 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20842 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20843 Javier Miranda <miranda@adacore.com>
20845 * sem_type.adb (Write_Overloads): Improve display of candidate
20847 (Add_One_Interp): Do not add to the list of interpretations aliased
20848 entities corresponding with an abstract interface type that is an
20849 immediate ancestor of a tagged type; otherwise we have a dummy
20850 conflict between this entity and the aliased entity.
20851 (Disambiguate): The predefined equality on universal_access is not
20852 usable if there is a user-defined equality with the proper signature,
20853 declared in the same declarative part as the designated type.
20854 (Find_Unique_Type): The universal_access equality operator defined under
20855 AI-230 does not cover pool specific access types.
20856 (Covers): If one of the types is a generic actual subtype, check whether
20857 it matches the partial view of the other type.
20859 2006-02-13 Thomas Quinot <quinot@adacore.com>
20861 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20862 line. This is necessary to allow In_Extended_Main_Unit to provide
20863 correct results for itypes while writing out expanded source.
20864 (Close_File): No need to update the source_index_table here since it's
20865 now done for each line.
20867 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20868 Robert Dewar <dewar@adacore.com>
20870 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20871 preserve the source unit where the itype is declared, and prevent a
20873 (Note_Implicit_Run_Time_Call): New procedure
20874 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
20877 * sprint.ads: Document use of $ for implicit run time routine call
20879 2006-02-13 Quentin Ochem <ochem@adacore.com>
20881 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
20884 2006-02-13 Bob Duff <duff@adacore.com>
20886 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20887 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20888 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20889 raise Constraint_Error.
20891 * s-vallli.adb (Scan_Long_Long_Integer): Call
20892 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20893 do not scan leading blanks and sign twice.
20894 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20895 raise Constraint_Error.
20897 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20898 Scan_Long_Long_Unsigned): Split out most of the processing from
20899 Scan_Long_Long_Unsigned out into
20900 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20901 This prevents scanning leading blanks and sign twice.
20902 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20905 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20906 out most of the processing from Scan_Unsigned out into
20907 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20908 This prevents scanning leading blanks and sign twice.
20910 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20911 use with Modular'Value attribute.
20912 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
20915 2006-02-13 Robert Dewar <dewar@adacore.com>
20917 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
20919 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>
20921 * tracebak.c (PPC AIX/Darwin): Define FORCE_CALL to 1.
20922 (PPC VxWorks): Likewise.
20923 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
20924 (forced_callee): Make non-inlinable and non-pure.
20925 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

20928 Ben Brosgol <brosgol@adacore.com>
20929 Robert Dewar <dewar@adacore.com>
20931 * gnat_rm.texi, gnat_ugn.texi: Remove limitations with sparc m64
20933 Document that gnatbind -M option is for cross environments only.

21038 Targparm.OpenVMS_On_Target.
21039 (Object_Suffix): Initialize with call to Get_Target_Object_Suffix.
21040 ({declaraction},Delete_Binder_Generated_Files,{initialization}): Change
21041 Ada bind file prefix on VMS from b$ to b__.
21043 * gnatlink.adb (Process_Args): Call Add_Src_Search_Dir for -I in
21044 --GCC so that Get_Target_Parameters can find system.ads.
21045 (Gnatlink): Call Get_Target_Parameters in mainline.
21046 Initialize standard packages for Targparm.
21047 Change some Hostparm.OpenVMS checks to Targparm.OpenVMS_On_Target.

21066 * Makefile.in: add support for vxworks653 builds
21067 (../../vxaddr2line): gnatlink with targext.o.
21068 (TOOLS_LIBS): Move targext.o to precede libgnat.
21069 (init.o, initialize.o): Minor clean up in dependencies.
21070 (GNATLINK_OBJS): Add targparm.o, snames.o

21108 Florian Villoing <villoing@adacore.com>
21110 * a-taster.ads, a-taster.adb: New files.
21112 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21113 link to the version that does nothing. This way the task termination
21114 routine is not executed twice for the environment task when finishing
21115 because of an unhandled exception.
21117 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21118 handler because of an unhandled exception.
21120 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
21121 System.Tasking.Utilities instead of that in System.Tasking.Stages.
21123 * s-finimp.adb (initialization code): Modify the soft link for the
21124 finalization of the global list instead of Adafinal.
21126 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21127 non-tasking version of the soft link for task termination. We do
21128 nothing since if we are using the non-tasking version it
21129 means that the task termination functionality is not used.
21130 (Null_Finalize_Global_List): Add this null version for the procedure
21131 in charge of finalizing the global list for controlled objects.
21132 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21133 instead for handling run-time termination in a more flexible way.
21134 (Adafinal_NT): This new procedure will take care of finalizing the
21135 global list for controlled objects if needed, but no tasking
21138 * s-tarest.adb (Task_Lock): Do not try to lock again the
21139 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21140 some run-time operations.
21141 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21142 until all nested locks have been released.
21143 (Task_Wrapper): Call the fall-back task termination handler. It
21144 applies to all tasks but the environment task.
21145 (Finalize_Global_Tasks): Add the call for the task termination
21146 procedure for the environment task.
21147 (Task_Wrapper): suppress warnings around declaration of
21148 Secondary_Stack_Address.
21150 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21151 moved to the Common_ATCB record.
21152 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21153 Common_ATCB record.
21154 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21155 Common_ATCB record.
21157 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21158 Fall_Back_Handler, and Specific_Handler.
21160 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21161 defined in Ada.Task_Termination, to avoid circular dependencies.
21162 (Termination_Handler): Redefine this type here, alredy defined in
21163 Ada.Task_Termination, for avoiding circular dependencies.
21164 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21165 for storing task termination handlers. In addition,
21166 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21167 Common_ATCB because it is used by both the regular and the restricted
21169 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21170 Common_ATCB because it is used by both the regular and the restricted
21172 (Common_ATCB): Added a dynamic task analyzer field.
21174 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21175 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21176 (Task_Wrapper): Call the task termination handler. It applies to all
21177 tasks but the environment task.
21178 (Finalize_Global_Tasks): Call the task termination procedure for the
21179 environment task. The call to Finalize_Global_List is now performed
21180 using the soft links mechanism.
21181 (Task_Wrapper): added dynamic stack analysis.
21183 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21184 potentially blocking operations has been moved from
21185 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21186 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21187 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21188 this run-time check.
21190 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version

21239 (Displace): New subprogram that displaces the pointer to the object
21240 to reference one of its secondary dispatch tables.
21241 (IW_Membership): Modified to use the new table of interfaces.
21242 (Inherit_TSD): Modified to use the new table of interfaces.

21263 have to use the Offset_To_Top run-time function to get this information;
21264 otherwise if the pointer to the base of the object has been displace
21265 we get a wrong value if we use the 'position attribute.
21267 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21268 all the calls to Expand_Interface_Thunk.

21305 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21306 Init_Secondary_Tags_Internal to allow its use with interface types and
21307 also to generate the code for the new additional actual required
21308 by Set_Offset_To_Top.
21309 (Build_Init_Statements): In case of components associated with abstract
21310 interface types there is no need to generate a call to its IP.

21337 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21338 about the use and expansion of SAVE_EXPRs in the various possible
21339 renaming handling cases.
21340 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by

21511 are implemented by the ancestors.
21512 (Derived_Type_Declaration): If the parent of the full-view is an
21513 interface perform a transformation of the tree to ensure that it has
21514 the same parent than the partial-view. This simplifies the job of the
21515 expander in order to generate the correct object layout, and it is
21516 needed because the list of interfaces of the full-view can be given in
21518 (Process_Full_View): The parent of the full-view does not need to be
21519 a descendant of the parent of the partial view if both parents are
21521 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21522 "limited" the parent must be a limited type.

21599 attributes are visible at the point of the subprogram declaration.
21600 For Ada 2005, the error message is modified to indicate that the

21874 deal with different cases of static and dynamic elaboration checks (all
21875 checks does not count in the first case, but does in the second).

21881 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
21882 elementary types using the operator in standard. It is cleaner not to
21883 modify the programmers intent, especially in the case of floating-point.
21884 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
21885 it did not matter because we always rewrote a/=b to not(a=b).
21886 (Expand_Allocator_Expression): For an allocator expression whose nominal
21887 subtype is an unconstrained packed type, convert the expression to its
21888 actual constrained subtype.
21889 Implement warning for <= or >= where < or > not possible
21890 Fix to Vax_Float tests (too early in many routines, causing premature
21891 Vax_Float expansions.
21893 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
21894 to be used with packages and generic packages as well as with

21897 of pragma Suppress (All_Checks)
21898 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
21899 a string literal for precise control over warnings.

21909 Allow optional = after -gnatm
21910 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
21911 longer sets Elaboration_Checks.
21912 Code to set warning mode moved to Sem_Warn
21913 so that it can be shared by pragma processing.
21915 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
21918 * s-taprop-solaris.adb:
21919 Change some <= to =, to avoid new warning

21925 2005-11-14 Robert Dewar <dewar@adacore.com>
21927 * exp_vfpt.adb: Handle /= case
21928 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
21929 so that we do not get duplicate scaling for fixed point conversions.
21931 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
21933 2005-11-14 Matthew Gingell <gingell@adacore.com>
21935 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
21936 Increase default priority on Lynx from 15 to 17, and meet the Ada
21937 requirement that Default_Priority be ((Priority'First +
21938 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

22035 from a fat or thin pointer type and a constrained object type.
22036 (annotate_value): Handle BIT_AND_EXPR.
22037 (annotate_rep): Don't restrict the back annotation of inherited
22038 components to the type_annotate_only case.
22039 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
22040 we are not defining the type.
22041 <E_Record_Type>: Likewise.
22042 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22043 to get advantage of the new maybe_stabilize_reference interface, to
22044 ensure that what we reference is indeed stabilized instead of relying
22045 on assumptions on what the stabilizer does.
22046 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22047 type imported through a limited_with clause, use its non-limited view.
22048 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22050 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22051 of #if sections + explicit comparisons of convention identifiers.
22052 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
22053 before early-returning for certain types when code generation is
22055 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
22056 nullification of gnu_expr we do for objects with address clause and
22057 that we are not defining.
22058 (elaborate_expression_1): Do not create constants when creating
22059 variables needed by the debug info: the dwarf2 writer considers that
22060 CONST_DECLs is used only to represent enumeration constants, and emits
22062 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22063 object with an address clause into an indirect reference, drop the
22064 initializing expression.
22066 (STACK_CHECK_BUILTIN): Delete.
22067 (STACK_CHECK_PROBE_INTERVAL): Likewise.

22074 related): For a prefix that is a dereference of a fat or thin pointer,
22075 if there is an actual subtype provided by the front-end, use that
22076 subtype to build an actual type with bounds template.
22077 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22078 is provided by the front-end, use that subtype to compute the size of
22079 the deallocated object.
22080 (gnat_to_gnu): When adding a statement into an elaboration procedure,
22081 check for a potential violation of a No_Elaboration_Code restriction.
22082 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22083 with extra arguments to control whether to recurse through non-values
22084 and to let the caller know if the stabilization has succeeded.

22086 maybe_stabilize, for common uses without restriction on lvalues and
22087 without need to check for the success indication.
22088 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22089 pass false instead of 0 as the FORCE argument which is a bool.
22090 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22091 attached to a renaming pointer has been properly stabilized, as no such
22092 object is attached otherwise.
22093 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22094 function uses the "target pointer" return mechanism.
22095 Reinstate conversion of the actual to the type of the formal
22096 parameter before any other specific treatment based on the passing
22097 mechanism. This turns out to be necessary in order for PLACEHOLDER
22098 substitution to work properly when the latter type is unconstrained.
22100 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
22102 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22103 with extra arguments to control whether to recurse through non-values
22104 and to let the caller know if the stabilization has succeeded.
22106 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22107 static output of record constructor if all the components are constant.
22108 (gnat_build_constructor): For a record type, sort the list of field
22109 initializers in increasing bit position order.
22110 Factor common code to build a storage type for an unconstrained object
22111 from a fat or thin pointer type and a constrained object type.
22112 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22113 types variants, and process special cases of VIEW_CONVERT expressions
22114 as their NOP_EXPR counterpart to ensure we get to the
22115 CORRESPONDING_VARs associated with CONST_DECls.
22116 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22117 on the right-hand side.
22119 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
22121 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
22122 are converting back to its original type.
22123 (convert) <JM input>: Fallthrough regular conversion code instead of
22124 extracting the object if converting to a type variant.
22125 (create_var_decl): When a variable has an initializer requiring code
22126 generation and we are at the top level, check for a potential violation
22127 of a No_Elaboration_Code restriction.
22128 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22129 SIZE and SIZE_UNIT which we need for later back-annotations.
22130 * utils.c: (convert) <STRING_CST>: Remove obsolete code.
22131 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
22132 is an unchecked union.
22133 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22134 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22135 main variant, just replace the VIEW_CONVERT_EXPR.
22136 <UNION_TYPE>: Revert 2005-03-02 change.
22138 * repinfo.h, repinfo.ads: Add tcode for BIT_AND_EXPR.

22271 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22272 for task component, in the case of a limited aggregate. The enclosed

22310 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
22311 and related): For a prefix that is an explicit dereference of an
22312 access to unconstrained packed array type, annotate the dereference
22313 with an actual subtype so GIGI can make a correct size computation.
22314 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22315 'Unrestricted_Access, if the designated type is an interface we
22316 add a type conversion to force the displacement of the pointer
22317 to the secondary dispatch table.
22318 Use Universal_Real instead of Long_Long_Float when we need a high
22319 precision float type for the generated code (prevents gratuitous
22320 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22321 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22322 'Terminated for task interface class-wide objects. Generate a call to
22323 the predefined dispatching routine used to retrieve the _task_id from
22324 a task corresponding record.

22346 necessary for the statements within the block: analyze it with checks
22348 (Expand_N_If_Statement): When killing a dead then-branch in an
22349 if-statement that has elsif_parts, recompute the Current_Value node
22350 for any entity whose value is known from the condition of the first
22352 (Expand_N_Return_Statement): When returning a mutable record, convert
22353 the return value into its actual subtype in order to help the backend
22354 to return the actual size instead of the maximum. This is another
22355 aftermath of not returning mutable records on the sec-stack anymore.
22357 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
22358 handling of error msg for suspicious reverse range iteration.

22374 a process handle, not need to convert.
22375 (__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.
22377 * g-expect.adb: (Kill): Document the new close parameter.
22378 (Close): Do not release the process handle in the kill there as

22382 2005-11-14 Robert Dewar <dewar@adacore.com>
22384 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we
22385 need a high precision float type for the generated code (prevents
22386 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
22389 * exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we
22390 need a high precision float type for the generated code (prevents

22402 subtype to compute the size of the designated object at run-time,
22403 create such a subtype and store it in the Actual_Designated_Subtype
22404 attribute of the N_Free_Statement.
22405 Generate itype for classwide designated object in both cases of
22406 user-specified storage pool: specific and class-wide, not only in the
22408 Raise CE when trying to set a not null access type object to null.
22409 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
22410 an explicit loop, because freeze nodes make its position variable.

22635 call, rewrite as a qualified expression to preserve some type
22636 information, to resolve possible ambiguities in the instance.
22637 (Instance_Parent_Unit): New global variable to record the ultimate
22638 parent unit associated with a generic child unit instance (associated
22639 with the existing Parent_Unit_Visible flag).

22646 not already set. Replace test of Is_Child_Unit with test of parent's
22647 scope against package Standard. Add comments and a ??? comment.
22648 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
22649 on a child instance parent to test that the parent equals

22664 * sem_ch3.ads, sem_ch3.adb (Build_Discriminal): Add link to original
22666 (Build_Private_Derived_Type): The entity of the created full view of the
22667 derived type does not come from source. If after installing the private
22668 declarations of the parent scope the parent is still private, use its
22669 full view to construct the full declaration of the derived type.
22670 (Build_Derived_Record_Type): Relax the condition that controls the
22671 execution of the check that verifies that the partial view and
22672 the full view agree in the set of implemented interfaces. In
22673 addition, this test now only takes into account the progenitors.
22674 (Derive_Interface_Subprograms): No need to derive subprograms
22675 of ancestors that are interfaces.
22676 (Derive_Subprograms): Remove formal No_Predefined_Prims and the

22679 (Complete_Subprograms_Derivation): Handle the case in which the full
22680 view is a transitive derivation of the ancestor of the partial view.
22681 (Process_Full_View): Rename local subprogram Find_Interface_In_
22682 Descendant to Find_Ancestor_Interface to leave the code more clear.
22683 Remove wrong code that avoids the generation of an error message
22684 when the immediate ancestor of the partial view is an interface.
22685 In addition some minor reorganization of the code has been done to
22686 leave it more clear.
22687 (Analyze_Type_Declaration): If type has previous incomplete tagged
22688 partial view, inherit properly its primitive operations.

22698 declared as an access to its own classwide type, to prevent cascaded
22700 (Collect_Interfaces): For private extensions and for derived task types
22701 and derived protected types, the parent may be an interface that must
22702 be included in the interface list.
22703 (Access_Definition): If the designated type is an interface that may
22704 contain tasks, create Master_Id for it before analyzing the expression
22705 of the declaration, which may be an allocator.
22706 (Record_Type_Declaration): Set properly the interface kind, for use
22707 in allocators, the creation of master id's for task interfaces, etc.

22730 package associated with a generic instance or formal package, the
22731 private declarations of the parent must be installed (by calling new
22732 procedure Install_Parent_Private_Declarations).
22733 Change name Is_Package to Is_Package_Or_Generic_Package
22734 (Preserve_Full_Attributes): For a synchronized type, the corresponding
22735 record is absent in a generic context, which does not indicate a

22740 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22741 not try to rewrite a renamed stream attribute, because the operations
22742 on the type may not have been generated.
22743 Handle properly a renaming_as_body generated for a stream operation
22744 whose default is abstract because the object type itself is abstract.
22745 (Find_Type): If the type is incomplete and appears as the prefix of a
22746 'Class reference, it is tagged, and its list of primitive operations
22747 must be initialized properly.
22748 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22749 private declaration of a parent unit, prior to compiling the private
22750 part of a child unit, find on the scope stack the proper parent entity
22751 on which to link the use clause.
22752 (Note_Redundant_Use): Emit a warning when a redundant use clause is
22754 (Analyze_Object_Renaming): An attribute reference is not a legal object
22755 if it is not a function call.

22771 * sem_res.adb (Resolve_Call): Provide a better error message whenever
22772 a procedure call is used as a select statement trigger and is not an
22773 entry renaming or a primitive of a limited interface.
22774 (Valid_Conversion): If the operand has a single interpretation do not
22775 remove address operations.
22776 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22777 statement to inhibit warning.
22778 (Resolve_Unary_Op): Do not produce a warning when
22779 processing an expression of the form -(A mod B)
22780 Use Universal_Real instead of Long_Long_Float when we need a high
22781 precision float type for the generated code (prevents gratuitous
22782 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22783 (Resolve_Concatenation_Arg): Improve error message when argument is an
22784 ambiguous call to a function that returns an array.
22785 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
22786 there is an implicit operator in the given scope if we are within an
22787 instance: legality check has been performed on the generic.

23369 (Expand_Allocator_Expression): Add tests for suppression of the AI-344
23370 check for proper accessibility of the operand of a class-wide allocator.
23371 The check can be left out if checks are suppressed or if the expression

23737 2005-09-01 Robert Dewar <dewar@adacore.com>
23739 * errout.ads, errout.adb (Fix Error_Msg_F): Fix implementation to meet
23741 Implement new insertion char < (conditional warning)
23742 * errutil.adb, erroutc.adb: Implement new insertion char <
23743 (conditional warning).
23744 * sem_elab.adb, prj-dect.adb, erroutc.ads, err_vars.ads
23745 (Error_Msg_Warn): New variable for < insertion char.
23746 * prj-nmsc.adb: Implement new errout insertion char < (conditional
23748 (Check_For_Source): Change value of Source_Id only after the current
23749 source has been dealt with.
23751 2005-09-01 Robert Dewar <dewar@adacore.com>
23752 Doug Rupp <rupp@adacore.com>
23754 * exp_attr.adb: Handle vax fpt for 'Valid attribute
23755 * exp_vfpt.ads, exp_vfpt.adb: (Expand_Vax_Valid): New procedure
23756 * s-vaflop-vms-alpha.adb, s-vaflop.ads, s-vaflop.adb
23757 (Valid_D, Valid_F, Valid_G): New functions
23759 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23760 Hristian Kirtchev <kirtchev@adacore.com>
23761 Javier Miranda <miranda@adacore.com>
23763 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23764 from object notation, the original node is unanalyzed and carries no
23765 semantic information, so that accessiblity checks must be performed on
23766 the type of the actual itself.
23767 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23768 compatibility with Build_Protected_Sub_Specification.
23769 (Check_Overriding_Inherited_Interfaces): Add suport to handle
23770 overloaded primitives.
23771 (Register_Interface_DT_Entry): Use the new name of the formal
23772 the the calls to Expand_Interface_Thunk
23774 * exp_dbug.ads: Augment comments on encoding of protected types to
23775 include the generation of dispatching subprograms when the type
23776 implements at least one interface.
23778 * lib.ads: Extend information in Load_Stack to include whether a given
23779 load comes from a Limited_With_Clause.
23781 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23782 whether a potential circularity is harmless, because it includes units
23783 loaded through a limited_with clause. Extends previous treatment which
23784 did not handle properly arbitrary combinations of limited and
23785 non-limited clauses.
23787 2005-09-01 Nicolas Setton <setton@adacore.com>
23789 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
23790 to be encoded as typ___XBLU_lowerbound__upperbound instead of
23791 typ___XB_lowerbound__upperbound.
23793 2005-09-01 Thomas Quinot <quinot@adacore.com>
23795 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
23796 dummy access formal for RACW/RAS TypeCode TSS.
23797 (Build_TypeCode_Call): Do not generate dummy null access actual for
23798 calls to the TypeCode TSS.
23800 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23802 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
23803 fully qualified name, to distinguish instances with the same local name.
23805 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
23808 2005-09-01 Robert Dewar <dewar@adacore.com>
23810 * exp_pakd.adb (Create_Packed_Array_Type): Properly handle very large
23813 2005-09-01 Jerome Lambourg <lambourg@adacore.com>
23815 * g-expect.adb (Non_Blocking_Spawn): Initialize the filters field to
23816 (Free): New deallocation procedure for filter elements
23817 (Close): Deallocate any existing filter for the concerned connection
23819 2005-09-01 Laurent Pautet <pautet@adacore.com>
23821 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
23822 position set is provided, we compute one in order to reduce the maximum
23823 length of the keys. This computation first selects a character
23824 position between 1 and the minimum length of the keys in order to
23825 avoid reducing one of the keys to an empty string.
23826 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23827 does not converge. The initialization procedure now comes with a
23828 maximum number of iterations such that when exceeded, an exception is
23829 raised in Compute. The user can initialize this ratio to another value
23831 Reformating and updated headers.
23833 2005-09-01 Javier Miranda <miranda@adacore.com>
23835 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
23836 that given an entity T creates and returns an Itype that duplicates the
23837 contents of T. The returned Itype has the null-exclusion
23838 attribute set to True, and its Etype attribute references T
23839 to keep the association between the two entities.
23840 Update copyright notice
23842 * sem_aggr.adb (Check_Can_Never_Be_Null,
23843 Aggregate_Constraint_Checks, Resolve_Aggregate,
23844 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
23846 * sem_ch5.adb (Analyze_Assignment): Code cleanup.
23848 2005-09-01 Gary Dismukes <dismukes@adacore.com>
23849 Robert Dewar <dewar@adacore.com>
23850 Hristian Kirtchev <kirtchev@adacore.com>
23852 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
23855 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
23857 Call Set_Result_Definition instead of Set_Subtype_Mark.
23858 (P_Subprogram_Specification): Add parsing of anonymous access result
23859 plus null exclusions. Call Set_Result_Definition instead of
23862 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23863 (P_Access_Type_Definition): Add parsing for an anonymous access result
23864 subtype, plus parsing for null exclusions. Call Set_Result_Definition
23865 instead of Set_Subtype_Mark.
23867 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23868 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
23869 (Result_Definition): New function for N_Function_Specifications.
23870 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
23871 N_Function_Specification.
23872 (Set_Null_Exclusion_Present): Allow this flag for
23873 N_Function_Specification.
23874 (Set_Result_Definition): New procedure for N_Function_Specifications.
23875 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
23876 and N_Function_Specification.
23878 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
23879 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
23880 Add support for LIMITED NEW for Ada 2005 AI-419
23881 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
23882 syntax for anonymous access results.
23883 Replace Subtype_Mark field by Result_Definition in
23884 N_Function_Specification and N_Access_Definition specs.
23885 Add Null_Exclusion_Present to spec of N_Function_Specification.
23886 (Result_Definition): New function for N_Function_Specification and
23887 N_Access_Function_Definition.
23888 (Set_Result_Definition): New procedure for N_Function_Specification and
23889 N_Access_Function_Definition.
23891 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
23892 Result_Definition for cases of N_Access_Function_Definition and
23893 N_Function_Specification.
23894 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
23896 2005-09-01 Vincent Celier <celier@adacore.com>
23898 * lib-writ.adb: Update Copyright notice
23899 (Write_With_Lines): On platforms where file names are case-insensitive,
23900 record the file names in lower case.
23901 (Write_ALI): For D lines, on platforms where file names are
23902 case-insensitive, record the file names in lower case.
23904 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23905 Emmanuel Briot <briot@adacore.com>
23907 * lib-xref.adb (Output_Overridden_Op): Display information on
23908 overridden operation.
23910 * lib-xref.ads: Add documentation on overridden operations.
23912 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
23915 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
23916 overriding entity information.
23918 2005-09-01 Vincent Celier <celier@adacore.com>
23920 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
23921 including those that are inherited.
23923 2005-09-01 Robert Dewar <dewar@adacore.com>
23925 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
23927 * par-prag.adb: Implement new pragma Debug_Policy
23929 * sem_prag.adb Implement new pragma Debug_Policy
23930 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23931 Component_Size attribute specification. Give warning for ignored pragma
23934 * snames.h, snames.ads, snames.adb: Introduce entries in
23935 Preset_Names for Name_Disp_Asynchronous_Select,
23936 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23937 Name_Disp_Timed_Select.
23938 New pragma Debug_Policy
23940 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23942 Switch -gnata also sets Debug_Pragmas_Enabled
23944 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23945 handle an explicit -gnata when compiling predefined files.
23947 2005-09-01 Vincent Celier <celier@adacore.com>
23949 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23950 directories of projects that have no Ada sources.
23952 2005-09-01 Robert Dewar <dewar@adacore.com>
23954 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23955 (makes a difference for wide characters)
23957 * widechar.adb, widechar.ads:
23958 Add Wide_Char_Byte_Count feature to count chars vs bytes
23960 2005-09-01 Thomas Quinot <quinot@adacore.com>
23961 Ed Schonberg <schonberg@adacore.com>
23962 Robert Dewar <dewar@adacore.com>
23964 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23965 'Address attribute reference with an overloaded prefix, use the
23966 location of the prefix (not the location of the attribute reference) as
23967 the error location.
23968 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23969 a function renaming thereof, is a valid prefix for 'Size (where it is
23970 intepreted as a function call).
23971 (Statically_Denotes_Entity): New predicate to determine whether the
23972 prefix of an array attribute can be considered static.
23975 (Eval_Attr): Fix failure to evaluate Component_Size for
23976 unconstrained arrays (resulted in wrong value in packed case, since
23977 back end cannot handle this case)
23979 2005-09-01 Robert Dewar <dewar@adacore.com>
23981 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23982 error msgs for most common cases.
23983 Use new errout insertion char < (conditional warning)
23985 2005-09-01 Javier Miranda <miranda@adacore.com>
23986 Ed Schonberg <schonberg@adacore.com>
23988 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23989 become local to the whole package.
23990 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23991 the package was already analyzed the new algorithm "replaces" the
23992 real entities by the shadow ones. This is required to ensure that
23993 the order of these entities in the homonym chains does not change;
23994 otherwise we can have undefined references at linking time because
23995 in case of conflicts the external name of the entities will have
23996 a suffix that depends on the order of the entities in the chain.
23997 (Remove_Limited_With_Clause): Complementary code that completes the
23998 new algorithm and replaces the shadow entities by the real ones.
23999 (Install_Limited_Withed_Unit): When unchaining entities before the
24000 installation of the shadow entities, only regular entities of the
24001 public part must be taken into account. This is required to
24002 keep this routine in synch with the work done by Remove_Limited_
24004 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24005 even if unit is analyzed, because the analysis of the unit is
24006 idempotent in any case, and the limited view of the unit may have to
24007 be installed for proper visibility.
24008 (Expand_Limited_With_Clause): Even if the unit in the implicit
24009 with_clause has been analyzed already, a limited view of the package
24010 must be built for the current context, if it does not exist yet.
24012 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24013 Javier Miranda <miranda@adacore.com>
24014 Gary Dismukes <dismukes@adacore.com>
24016 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24017 defining entity for the instance body, make a new defining identifier
24018 rather than copying the entity of the spec, to prevent accidental
24019 sharing of the entity list.
24020 (Check_Private_View): When exchanging views of private types, build the
24021 list of exchanged views as a stack, to ensure that on exit the exchanges
24022 are undone in the proper order.
24023 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24024 Restore the compilation environment in case of instantiation_error.
24025 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24026 for an anonymous access result.
24027 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24028 (Formal_Entity): Handle properly the case of a formal package that
24029 denotes a generic package renaming.
24031 2005-09-01 Thomas Quinot <quinot@adacore.com>
24033 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24034 clause if the array aggregate is surrounded by parentheses.
24036 2005-09-01 Cyrille Comar <comar@adacore.com>
24037 Gary Dismukes <dismukes@adacore.com>
24038 Ed Schonberg <schonberg@adacore.com>
24039 Javier Miranda <miranda@adacore.com>
24041 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24043 to check if a type is Constrained in cases related to code generation
24044 (rather than semantic checking) since otherwise we do not generate
24045 similar code for mutable private types depending if their
24046 discriminants are visible or not.
24047 (Check_Abstract_Overriding): Do not complain about failure to override
24048 the primitive operations used in dispatching selects since they will
24049 always be overriden at the freeze point of the type.
24050 (Access_Definition): Separate out handling for resetting the scope
24051 of an anonymous access function result type. Retrieve the scope
24052 of the associated function rather than using Current_Scope, which
24053 does not have a consistent value (depends on whether we're in the
24054 middle of analyzing formal parameters). Add ??? comment about
24055 finding a cleaner way to handle the special cases of scope setting.
24056 (Process_Incomplete_Dependents): A protected operation is never a
24057 dispatching operation (only its wrapper may be).
24058 (Build_Derived_Record_Type): In case of tagged private types that
24059 implement interfaces add derivation of predefined primitive
24061 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24062 by two parameters that are used in case of derivation from abstract
24063 interface types: No_Predefined_Prims is used to avoid the derivation
24064 of predefined primitives from the interface, and Predefined
24065 Prims_Only is used to complete the derivation predefined primitives
24066 in case of private tagged types implementing interfaces.
24067 Fix typo in comments
24068 (Find_Interface_In_Descendant): Protect the frontend against
24069 wrong code with large circularity chains.
24070 (Is_Private_Overriding): Add support for entities overriding interface
24071 subprograms. The test failed because Entities associated with overriden
24072 interface subprograms are always marked as hidden (and used to build
24073 the secondary dispatch table); in this case the overriden entity is
24074 available through the field abstract_interface_alias (cf. override_
24075 dispatching_operation)
24076 (Access_Definition): Set the scope of the type to Current_Scope for the
24077 case of a function with an anonymous access result type.
24078 (Access_Subprogram_Declaration): Handle creation of the type entity for
24079 an access-to-function type with an anonymous access result.
24080 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24081 in handling for N_Access_Function_Definition.
24082 (Analyze_Subtype_Declaration): Modify the text of error message.
24083 (Derived_Type_Declaration): Modify the text of error message.
24084 (Process_Subtype): Modify the text of error message plus cleanup
24085 of one redundant error message.
24086 (Analyze_Component_Declaration): Code cleanup.
24087 (Analyze_Object_Declaration): Code cleanup.
24088 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24089 attribute in case of access types. Code cleanup.
24090 (Array_Type_Declaration): Code cleanup.
24091 (Process_Discriminants): Create the new null-excluding itype
24092 if required. Code cleanup.
24093 (Process_Subtype): Create the new null-excluding itype if
24094 required. Code cleanup.
24095 (Build_Derived_Record_Type): Code cleanup to avoid calling
24096 twice the subprogram derive_subprograms in case of private
24097 types that implement interfaces. In this particular case the
24098 subprogram Complete_Subprograms_Derivation already does the
24099 job associated with the second call.
24101 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24102 conversion to the full view when generating an operation for a
24103 discriminant whose type may currently be private.
24105 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24106 Javier Miranda <miranda@adacore.com>
24108 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24109 V (Obj.F), the rewriting does not involve the indexed component, but
24110 only the selected component itself.
24111 Do not apply the transformation if the analyzed node is an actual of a
24112 call to another subprogram.
24113 (Complete_Object_Operation): Retain the entity of the
24114 dispatching operation in the selector of the rewritten node. The
24115 entity will be used in the expansion of dispatching selects.
24116 (Analyze_One_Call): Improve location of the error message associated
24118 (Analyze_Selected_Component): No need to resolve prefix when it is a
24119 function call, resolution is done when parent node is resolved, as
24121 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24122 when attempting to resolve a call transformed from its object notation.
24123 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24124 of the argument list for each interpretation of the operation.
24125 (Try_Object_Operation): The designated type of an access parameter may
24126 be an incomplete type obtained through a limited_with clause, in which
24127 case the primitive operations of the type are retrieved from its full
24129 (Analyze_Call): If this is an indirect call, and the return type of the
24130 access_to_subprogram is incomplete, use its full view if available.
24132 2005-09-01 Javier Miranda <miranda@adacore.com>
24133 Gary Dismukes <dismukes@adacore.com>
24135 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24136 access types the null-exclusion and access-to-constant attributes must
24138 (Analyze_Return_Statement): When the result type is an anonymous access
24139 type, apply a conversion of the return expression to the access type
24140 to ensure that appropriate accessibility checks are performed.
24141 (Analyze_Return_Type): For the case of an anonymous access result type,
24142 generate the Itype and set Is_Local_Anonymous_Access on the type.
24143 Add ??? placeholder for check to disallow returning a limited object
24144 in Ada 2005 unless it's an aggregate or a result of a function call.
24145 Change calls from Subtype_Mark to Result_Definition.
24146 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24147 Result_Definition in call to Make_Function_Specification.
24148 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24149 Set_Result_Definition.
24150 (Make_Inequality_Operator): Change formal Subtype_Mark to
24151 Result_Definition in call to Make_Function_Specification.
24152 (Process_Formals): Create the new null-excluding itype if required.
24153 (New_Overloaded_Entity): For an entity overriding an interface primitive
24154 check if the entity also covers other abstract subprograms in the same
24155 scope. This is required to handle the general case, that is, overriding
24156 other interface primitives and overriding abstract subprograms inherited
24157 from some abstract ancestor type.
24158 (New_Overloaded_Entity): For an overriding entity that comes from
24159 source, note the operation that it overrides.
24160 (Check_Conformance, Type_Conformant): Addition of one new formal
24161 to skip controlling formals in the analysis. This is used to
24162 handle overloading of abstract interfaces.
24163 (Base_Types_Match): Add missing case for types imported from
24164 limited-with clauses
24165 (New_Overloaded_Entity): Add barrier to protect the use of
24166 the "alias" attribute.
24168 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24170 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24171 verify that the procedure and the entry are mode conformant.
24172 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24173 as a different operator, which is often a cut-and-paste error.
24175 2005-09-01 Javier Miranda <miranda@adacore.com>
24176 Ed Schonberg <schonberg@adacore.com>
24178 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24179 used in controlling parameters exclude null because it is necessary to
24180 read the tag to dispatch, and null has no tag.
24181 (Override_Dispatching_Operation): If the previous operation is inherited
24182 from an interface, it becomes hidden and does not participate in later
24185 2005-09-01 Javier Miranda <miranda@adacore.com>
24186 Ed Schonberg <schonberg@adacore.com>
24187 Gary Dismukes <dismukes@adacore.com>
24189 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24190 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24191 the expander will generate the corresponding run-time check to evaluate
24193 (Resolve_Call): Check for legal type of procedure name or prefix that
24194 appears as a trigger in a triggering alternative.
24195 (Valid_Conversion): If expression is ambiguous and the context involves
24196 an extension of System, remove System.Address interpretations.
24197 (Resolve_Qualified_Expression): Reject the case of a specific-type
24198 qualification applied to a class-wide argument. Enhance comment
24199 to explain checking of Original_Node.
24200 (Resolve_Type_Conversion): The location of the error message was not
24201 general enough to handle the general case and hence it has been removed.
24202 In addition, this patch improves the text of the message.
24203 (Resolve_Type_Conversion): Add missing support for access to interface
24205 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24206 do not expand if the expression is the actual in a call, because proper
24207 expansion will take place when the call itself is expanded.
24208 (Resolve_Allocator): If the context is an unchecked conversion, the
24209 allocator inherits its storage pool, if any, from the target type of

24215 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24216 inherited interface operation that has an implementation, use the
24217 implementation to avoid spurious ambiguities.
24218 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24219 use the Corresponding_Record_Typ attribute to look for the interface
24220 because it is set by the expander (and hence it is not always
24221 available). For this reason we traverse the list of interfaces
24222 (available in the parent of the concurrent type).

24232 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24234 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24235 capture if it is generated in the second operand of a short-circuit
24237 Do not capture values for variables with address clauses.
24238 (Is_Object_Reference): Treat a function call as an object reference only
24239 if its type is not Standard_Void_Type.
24241 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24243 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied

25026 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25027 longer protected objects. They have been replaced by lower-level
25028 suspension objects made up by a mutex and a condition variable (or
25029 their equivalent given a particular OS) plus some internal data to
25030 reflect the state of the suspension object.
25031 (Initialize, Finalize): Add this initialization procedure for
25032 Suspension_Object, which is a controlled type.
25033 (Finalize): Add the finalization procedure for Suspension_Object,
25034 which is a controlled type.

25059 object to True, releasing the task that was suspended, if any.
25060 (Suspend_Until_True): Add this procedure that blocks the calling task
25061 until the state of the object is True. Program_Error is raised if
25062 another task is already waiting on that suspension object.
25063 (Initialize): Add this procedure for initializing the suspension
25064 object. It initializes the mutex and the condition variable which are
25065 used for synchronization and queuing, and it sets the internal state

25074 which provides a low-level abstraction (using operating system
25075 primitives) for Ada.Synchronous_Task_Control.
25076 This object is made up by a mutex (for ensuring mutual exclusion), a
25077 condition variable (for queuing threads until the condition is
25078 signaled), a Boolean (State) indicating whether the object is open,

25470 error message condition, null procedures are correctly detected now.
25471 (New_Overloaded_Entity): Bypass trivial overriding indicator check

25487 subprogram_specification that returns true if some non
25488 class-wide interface subprogram is found

25491 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
25492 access to subprograms must be recursive.
25493 (Is_Unchecked_Conversion): Improve the test that recognizes
25494 instantiations of Unchecked_Conversion, and allows them in bodies that
25495 are to be inlined by the front-end. When the body comes from an

25518 object or component (that is, when Is_Local_Anonymous_Access is true).
25519 Prevent the special checks for conversions of access discriminants in
25520 the case where the discriminant belongs to a nonlimited type, since

25542 pragma Restrictions (No_Obsolescent_Features).
25543 (Check_Direct_Boolean_Operator): If the boolean operation has been
25544 constant-folded, there is nothing to check.
25545 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25546 check on possible violation of restriction No_Direct_Boolean_Operators
25547 until after expansion of operands, to prevent spurious errors when

25583 both bound checks, rather than a conjunction.
25584 (Insert_Valid_Check): If the expression is an actual that is an indexed
25585 component of a bit-packed array, force expansion of the packed element
25586 reference, because it is specifically inhibited elsewhere.

26504 (check dos line terminator).
26505 (Check_Line_Max_Length): New procedure, split off from the existing
26506 Check_Line_Terminator routine. Separating this out allows -gnatyf to
26507 be properly recognized.
26509 * styleg.adb: Add ??? comment for line terminator reference
26511 * scng.adb (Check_End_Of_Line): Fix bug of -gnatyf being ignored

26552 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26553 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26554 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26555 analyzed if expansion is disabled (which could otherwise cause spurious
26556 error messages if expansion has been disabled due to previous
26557 (unrelated) errors).
26559 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26560 is disabled, the entity denoted by the argument is the access type
26561 itself, not an underlying record type, so there is no need to go back
26562 to the Corresponding_Remote_Type.
26564 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26565 Robert Dewar <dewar@adacore.com>
26567 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
26568 expand a call to an instance of
26569 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
26570 Constructor actual of the instance. A class-wide membership
26571 check is also generated, to ensure that the tag passed to the instance
26572 denotes a type in the class.
26573 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26574 of Name_Generic_Dispatching_Constructor.
26576 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26577 05 unit for AI-260-02).
26579 * a-tgdico.ads: New file.

26589 character type cases.
26590 (Analyze_Subprogram_Renaming): Add special handling for
26591 the case of renaming of stream attributes when the renaming denotes a
26592 generic formal subprogram association for an abstract formal subprogram.
26593 Check that the attribute is a primitive stream attribute (and not
26594 a class-wide stream attribute) and then rewrite the attribute name
26595 as the name of the appropriate compiler-generated stream primitive.
26597 2005-03-29 Robert Dewar <dewar@adacore.com>
26599 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

26602 resulted in inaccurate result for unaligned scalars within records.
26604 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26606 * freeze.adb (Freeze_Record_Type): If the type of the component is an
26607 itype whose parent is controlled and not yet frozen, do not create a
26608 freeze node for the itype if expansion is disabled.
26610 2005-03-29 Vincent Celier <celier@adacore.com>
26612 * make.adb (Gnatmake): Don't fail if the main project file is declared
26613 as having no Ada sources. Do not display message "no sources to
26614 compile" in quiet output.
26616 2005-03-29 Doug Rupp <rupp@adacore.com>
26618 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as
26621 2005-03-29 Robert Dewar <dewar@adacore.com>
26623 * par-ch12.adb (P_Generic): Give better msg for illegal private generic
26626 2005-03-29 Robert Dewar <dewar@adacore.com>

26629 missing TYPE Improve the error message generated when compiling a
26630 limited interface in Ada83 or Ada95 mode.
26632 2005-03-29 Robert Dewar <dewar@adacore.com>
26634 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26635 rather than proceed ahead using a junk attribute name.
26637 2005-03-29 Vincent Celier <celier@adacore.com>
26639 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26641 * prj-part.adb (Parse_Single_Project): Set the location of a project
26642 on its defining identifier, rather than on the reserved word "project".
26644 * prj-proc.adb (Expression): Adapt to the fact that default of external
26645 references may be string expressions, not always literal strings.
26646 (Recursive_Process): Set Display_Name equal to Name
26647 when Location is No_Location, that is when there is no actual file.
26648 Get the Display_Name of the project from the source, when it is not a
26650 (Process): Use the Display_Name in error messages
26652 * prj-strt.adb (External_Reference): Allow default to be string
26653 expressions, not only literal strings.
26655 2005-03-29 Vincent Celier <celier@adacore.com>
26657 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
26658 file and the reference symbol file to be the same file.
26660 2005-03-29 Thomas Quinot <quinot@adacore.com>
26662 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
26663 forbid conversion of a local access-to-subprogram type to a remote one.
26665 * sem_util.adb (Wrong_Type): For a record type that is the expanded
26666 equivalent type for a remote access-to-subprogram type, go back to the
26667 original RAS entity when displaying an error message, so the casing is
26668 the original source casing.
26670 2005-03-29 Robert Dewar <dewar@adacore.com>
26672 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
26675 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26677 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26678 subtype if code is being pre-analyzed, to prevent un-expanded
26679 references to protected formals, among others.
26680 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26681 interpretation that can be a call, include the result of the call as a
26682 possible interpretation of the dereference.
26684 * sem_ch5.adb (Process_Bounds): Determine type of range by
26685 pre-analyzing a copy of the original range, and then analyze the range
26686 with the expected type.
26688 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26689 with an overloaded prefix where not all interpretations yield an
26690 access to subprogram, do not rewrite node as a call.
26691 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26692 the node as a call once the context identifies the interpretation of
26693 the prefix whose call yields the context type.
26694 (Valid_Conversion): For the case of a conversion between
26695 local access-to-subprogram types, check subtype conformance using
26696 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26697 detailed error message.
26699 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26701 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26702 indicator, indicate that the formal can never be null.
26703 (Process_Formals): If a formal has a non_null indicator, insert the
26704 resulting subtype immediately before the enclosing subprogram decl,
26705 and not at the beginning of the corresponding declarative part, to
26706 prevent access before elaboration (Ada2005).
26708 2005-03-29 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26711 * utils.c (finish_record_type): Use variable_size when setting sizes.

26811 the subprogram against wrong usage.
26812 Adapt the code to traverse the entities in the
26813 scope of a record_type because in addition to its usage regarding
26814 packages, this subprogram is also called by Expand_N_Freeze_Entity
26815 to install the visible declarations of the enclosing scope of a
26816 record_type_with_private to establish the proper visibility before
26817 freezing the entity and related subprograms.
26819 2005-03-17 Ed Schonberg <schonberg@adacore.com>
26821 * exp_ch2.adb (In_Assignment_Context): Recognize slice assignments to

26827 (Check_Stream_Attribute): Move the code for 13.13.2(9/1) enforcement
26828 into a new Check_Attr subprogram, in order to provide a more
26829 explanatory error message (including the name of the missing attribute).
26830 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
26831 subprogram determines whether a default implementation exists for a
26832 given stream attribute.
26833 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
26834 Determine whether to generate a default implementation for each stream
26835 attribute separately, as this depends on the specific attribute.
26837 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
26838 limited extension where a stream attribute is missing for a limited
26839 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not
26840 generate a bogus reference to the missing attribute to prevent

27315 Update documentation on Must_Be_Byte_Aligned for new spec
27317 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
27318 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
27319 uses of the Access_Disp_Table attribute to reference the first dispatch
27320 table associated with a tagged type. As
27321 part of the implementation of abstract interface types,
27322 Access_Disp_Table has been redefined to contain a list of dispatch
27323 tables (rather than a single dispatch table).
27324 Similarly, upgrade all the references to Tag_Component by the
27325 new attribute First_Tag_Component.
27326 (Find_Inherited_TSS): Moved to exp_tss.
27327 Clean up test in Expand_N_Object_Declaration for cases
27328 where we need to do a separate assignment of the initial value.
27329 (Expand_N_Object_Declaration): If the expression in the
27330 declaration of a tagged type is an aggregate, no need to generate an
27331 additional tag assignment.
27332 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
27334 Bit packed array ops are only called if operands are known to be
27336 (Component_Equality): When returning an N_Raise_Program_Error statement,
27337 ensure that its Etype is set to Empty to avoid confusing GIGI (which
27338 expects that only expressions have a bona fide type).
27339 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
27340 determine the amount of data to be copied.
27342 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
27343 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
27344 INTERFACE_TYPE_DEFINITION ::=
27345 [limited | task | protected | synchronized] interface
27346 [AND interface_list]
27348 * par-ch3.adb (P_Type_Declaration): Modified to give support to
27350 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
27352 (P_Interface_Type_Definition): New subprogram that parses the new
27353 syntax rule of Ada 2005 interfaces
27354 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
27355 messages by the correct RENAMES (quotes removed).
27357 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
27358 attribute First_Tag_Component.
27360 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
27361 (Interface_List, Set_Interface_List): New subprograms.
27362 (Interface_Present, Set_Interface_Present): New subprograms.
27363 (Limited_Present, Set_Limited_Present): Available also in derived
27364 type definition nodes.
27365 (Protected_Present, Set_Protected_Present): Available also in
27366 record type definition and
27367 derived type definition nodes.
27368 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
27369 (Task_Present, Set_Task_Present): New subprogram.
27370 (Task_Body_Procedure): Removed.
27371 (Set_Task_Body_Procedure): Removed.
27372 These subprogram have been removed because the attribute
27373 Task_Body_Procedure has been moved to the corresponding task type
27374 or task subtype entity to leave a field free to store the list
27375 of interfaces implemented by a task (for AI-345)
27376 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27377 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27378 expression flag Do_Range_Check
27379 (Exception_Junk): Change to Flag7 to accomodate above change
27380 (Box_Present, Default_Name, Specification, Set_Box_Present,
27381 Set_Default_Name, Set_Specification): Expand the expression
27382 "X in N_Formal_Subprogram_Declaration" into the corresponding
27383 two comparisons. Required to use the csinfo tool.
27385 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
27386 "with string" given.
27388 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
27391 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
27394 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27395 attribute Task_Body_Procedure rather than the old semantic field that
27396 was available in the task_type_declaration node.
27398 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27399 interface type definitions.
27400 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27403 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
27404 task type declaration.
27405 (P_Protected): Modified to handle the list of interfaces in a
27406 protected type declaration.
27408 2005-03-15 Doug Rupp <rupp@adacore.com>
27409 Vincent Celier <celier@adacore.com>
27411 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27412 (Gen_Output_File_C): Likewise.
27413 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
27415 2005-03-15 Thomas Quinot <quinot@adacore.com>
27417 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27418 is an N_Raise_Constraint_Error node, create a new copy of it without
27419 going through a call to Duplicate_Subexpr.
27421 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
27422 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27423 Nicolas Setton <setton@adacore.com>
27424 Ed Schonberg <schonberg@adacore.com>
27430 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27431 representation clause that prescribes a size not equal to the rounded
27432 size of their types.
27433 (gnat_to_gnu_entity, case E_Component): Always look at
27434 Original_Record_Component if Present and not the entity.
27435 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27436 of tagged extension types by not making field for components that are
27438 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27439 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27440 expression to the type of the object when the object is constant.
27441 Reverse defer_debug_incomplete_list before traversing it, so that trees
27442 are processed in the order at which they were added to the list. This
27443 order is important when using the stabs debug format.
27444 If we are deferring the output of debug information, also defer this
27445 output for a function return type.
27446 When adding fields to a record, prevent emitting debug information
27447 for incomplete records, emit the information only when the record is
27449 (components_to_record): New parameter defer_debug.
27450 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27451 (gnat_to_gnu_field_decl): New function.
27452 (substitution_list, annotate_rep): Call it.
27453 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27454 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27455 No longer update discriminants to not be a COMPONENT_REF.
27456 (copy_alias_set): Strip padding from input type; also handle
27457 unconstrained arrays properly.
27459 * gigi.h (write_record_type_debug_info): New function.
27460 Convert to use ANSI-style prototypes. Remove unused
27461 declarations for emit_stack_check, elab_all_gnat and
27462 set_second_error_entity.
27463 (gnat_to_gnu_field_decl): New decl.
27465 * utils.c (write_record_type_debug_info): New function.
27466 (finish_record_type): Delegate generation of debug information to
27467 write_record_type_debug_info.
27468 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27469 (update_pointer_to): Fix pasto.
27470 (convert) <UNION_TYPE>: Accept slight type variations when
27471 converting to an unchecked union type.
27473 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27474 replace the N_Freeze_Entity with a null statement.
27476 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27477 within a constrained subcomponent of an enclosing record, place the
27478 freeze nodes in the scope stack entry for the enclosing record.
27479 (Undelay_Type): New Subprogram.
27480 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27481 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27482 within records; allow them to have freeze nodes if their base types
27485 * exp_util.adb (Remove_Side_Effects): Properly test for
27486 Expansion_Delayed and handle case when it's inside an
27487 N_Qualified_Expression.
27489 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27490 Comes_From_Generic, to recognize accurately that the parent type in a
27491 derived type declaration can be traced back to a formal type, because
27492 it is one or is derived from one, or because its completion is derived
27494 (Constrain_Component_Type): If component comes from source and has no
27495 explicit constraint, no need to constrain in in a subtype of the
27497 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27498 Minor change to propagate Is_Ada_2005 flag
27500 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27501 Expansion_Delayed is False.
27502 (assoc_to_constructor): Ignore fields that have a
27503 Corresponding_Discriminant.
27504 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27505 function returns "by target", dereference the target pointer using the
27506 type of the actual return value.
27507 <all>: Be prepared for a null gnu_result.
27508 (processed_inline_subprograms): Check flag_really_no_inline
27509 instead of flag_no_inline.
27510 (set_second_error_entity): Remove unused function.

27515 2005-03-15 Robert Dewar <dewar@adacore.com>
27516 Ed Schonberg <schonberg@adacore.com>
27517 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27519 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27520 Must_Be_Byte_Aligned for cases where we do not need to use a
27521 System.Pack_nn unit.
27523 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27525 Needed now that we do some processing for IN parameters as well. This
27526 may well fix some unrelated errors.
27527 (Expand_Call): Handle case of unaligned objects (in particular those
27528 that come from packed arrays).
27529 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27530 renamed entity is an inherited operation, re-expand the call using the
27531 original operation, which is the one to call.
27532 Detect attempt to inline parameterless recursive subprogram.
27533 (Represented_As_Scalar): Fix to work properly with private types
27534 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27535 accurate estimate. Yields True in far fewer cases than before,
27536 improving the quality of code that depends on this test.
27538 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27539 over both visible and private declarations to remove them from tree,
27540 and mark subprograms declared in package as eliminated, to prevent
27541 spurious use in subsequent compilation of generic units in the context.
27543 * exp_util.ads: Minor cleanup in variable names
27545 * sem_eval.ads, sem_eval.adb: Minor reformatting
27546 (Compile_Time_Known_Bounds): New function
27548 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27550 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27551 determining whether an unchecked conversion is needed for the argument
27552 of an initialization call.
27554 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27556 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27557 that appears in the instantiation rather than the internal subtype
27558 generated in the wrapper package, to avoid anomalies in gigi when the
27559 target is derived from a private type whose full view is an access type.
27561 2005-03-15 Robert Dewar <dewar@adacore.com>
27563 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27565 Add documentation to replace the use of this flag
27566 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27569 2005-03-15 Thomas Quinot <quinot@adacore.com>
27571 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27572 here from exp_attr so it can be shared between exp_attr and exp_dist.
27573 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27574 all TSS names, not a subset thereof, and the previous name introduced
27575 an unnecessarily confusion that a distinction might exist between
27576 "OK" TSS names and some "not OK" TSS names.
27578 2005-03-15 Doug Rupp <rupp@adacore.com>
27580 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27583 2005-03-15 Pascal Obry <obry@adacore.com>
27584 Eric Botcazou <ebotcazou@adacore.com>
27588 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27589 when IN_RTS. This is to work around a bootstrap path problem.
27591 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27592 table and pass it to __gnat_install_SEH_handler().
27593 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27595 * lang.opt: Fix specification of -fRTS=.
27597 2005-03-15 Doug Rupp <rupp@adacore.com>
27598 Bernard Banner <banner@adacore.com>
27599 Vincent Celier <celier@adacore.com>
27600 Arnaud Charlet <charlet@adacore.com>
27603 This change works fine when gnatlib is built from the gcc directory,
27604 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27605 is not passed to ada/Makefile.in, so more work is needed by a
27606 Makefile/configure expert.
27608 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27609 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27610 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27612 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27613 Run ranlib on libgccprefix.a
27614 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27615 (ADA_INCLUDE_SRCS): Split Ada packages.
27617 2005-03-15 Robert Dewar <dewar@adacore.com>
27619 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27621 * impunit.adb: Add GNAT.UTF_32
27623 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27625 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27626 now uses GNAT.UTF_32).
27628 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27629 capabilities for categorizing characters using Unicode categories
27631 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27633 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27634 instantiation that has been rewritten as a package body, retrieve spec
27635 to generate proper name for implicit_with_clause.
27636 (Install_Parents): Recognize a parent that is an instantiation but has
27637 been rewritten as a package declaration during analysis.
27639 2005-03-15 Javier Miranda <miranda@adacore.com>
27640 Ed Schonberg <schonberg@adacore.com>
27642 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27643 parameter reported some error we immediately return. This improves the
27644 behaviour of the frontend in case of errors.
27645 (Install_Parent, Remove_Parent): Introduce new flag
27646 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27647 ancestor of a generic child unit, when the child is being instantiated.
27648 (Inline_Instance_Body): If we are compiling the private
27649 part or the body of a child unit, restore the proper visibility of the
27650 parents after compiling the instance body.
27652 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27653 Javier Miranda <miranda@adacore.com>
27656 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27657 of a private type, in which case it is underlying_type that denotes
27658 the proper task. Also modified to use the new entity attribute
27659 that is directly available in the task type and task subtype entities
27660 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27661 arrays when other dimensions than the first are constrained by
27662 discriminants of an enclosing record.
27663 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27664 a combination of indexed and selected components, find ultimate entity
27665 and generate the appropriate reference for it, to suppress spurious
27667 (Note_Possible_Modification): If an entity name has no entity, return.
27668 (Is_Variable): A function call never denotes a variable.
27669 (Requires_Transient_Scope): For record types, recurse only on
27670 components, not on internal subtypes that may have been generated for
27671 constrained components.
27673 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27675 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27676 Eliminated as candidates for resolution. Both efficient, and avoids
27677 anomalies with operators declared in deleted code.
27678 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27679 expansion is disabled (as when compiling a generic) to prevent spurious
27680 warnings on prefixes of selected components.
27682 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27684 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27685 attached to a list before checking whether it appears in the private
27686 declarations of the current package.
27687 (Make_Inequality_Operator): Insert declaration in proper declarative
27688 list rather than just setting the Parent field, so that
27689 Is_Private_Declaration can handle it properly.
27691 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27693 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27694 a renaming a body, check that the renamed subprogram in not intrinsic.
27695 (Find_Direct_Name): If several use_visible entities hide
27696 each other, and the context is a predefined file compiled through
27697 rtsfind, keep only the entity that comes from a predefined file.
27699 2005-03-15 Geert Bosch <bosch@adacore.com>
27701 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27702 long float padding to also cover AMD64 and IA64.
27704 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27706 * s-imgwch.adb: Add with and use of Interfaces.
27707 (Img_Wide_Character): Change type of Val to Unsigned_16.
27708 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27710 2005-03-15 Matthew Gingell <gingell@adacore.com>
27712 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
27714 2005-03-15 Robert Dewar <dewar@adacore.com>
27716 * usage.adb: Add missing lines for -gnat95 and -gnat05 switches
27718 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
27720 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
27722 2005-03-15 Robert Dewar <dewar@adacore.com>

27745 * comperr.adb (Compiler_Abort): remove references to obsolete
27746 procedures in the bug boxes for various GNAT builds.
27748 2005-03-15 Vincent Celier <celier@adacore.com>
27750 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

27755 Cyrille Comar <comar@adacore.com>
27756 Sergey Rybin <rybin@adacore.com>
27758 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
27759 too specific and long-winded to be appropriate for the GNAT User's
27761 Warn about use of GCC switches not documented in the GNAT User's Guide,
27762 as these may cause generated code to not conform to Ada semantics.
27763 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
27764 Add documentation for -gnat95 and -gnat05 switches
27765 Remove paragraph documenting obsolete way to refer to third party
27767 Add a few references to Ada_05 that were missing.
27768 Update documentation on -gnatZ/-gnatL.
27769 Document limitation when using -m64 under Solaris.
27770 Change the "Name Casing" subsection of the pretty-printer section
27771 according to the changes in the dictionary processing.
27773 * gnat_rm.texi: Document the Ada_05 pragma.
27774 Section on record representation clauses describes the new more
27775 relaxed rules about placement of large packed bit array components.
27776 Add documentation of GNAT.UTF_32
27778 2005-03-12 Daniel Berlin <dberlin@dberlin.org>
27780 * misc.c (gnat_post_options): Turn off structural
27783 2005-03-08 Laurent Guerby <laurent@guerby.net>

28184 the formal subprogram.
28185 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28186 which is an unclean use of that field, we set the new field

28200 subprogram only if inner one comes from source.
28201 (Analyze_Function_Call): If the call is given in object notation, the

28205 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28206 mark in function specification, in a context where the formals are
28207 visible and hide outer homographs.
28209 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28210 as the tagged type for the cases of abstract formal subprograms and
28211 renamings of those. Clean up spec comments.
28212 (Check_Dispatching_Context): Add error message to indicate "abstract
28213 procedure", covering the case of a call to a formal abstract procedure
28214 that has statically tagged operands.
28215 (Check_Dispatching_Call): Check for the case of an actual given by
28216 a tag-indeterminate function call whose type is an ancestor of the
28217 containing call's associated tagged type. This situation can occur
28218 for inherited primitives with function defaults. In this case we
28219 use the tagged type's tag directly as the controlling argument for

28286 GNAT.OS_Lib.Set_Close_On_Exec.
28288 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
28289 the parent side as close-on-exec so that they are not inherited by the
28292 * g-os_lib.ads, g-os_lib.adb (Set_Close_On_Exec): New subprogram to
28293 set or clear the FD_CLOEXEC flag on a file descriptor.
28295 2005-02-09 Eric Botcazou <ebotcazou@adacore.com>
28296 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28300 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28301 on the field if Pragma Component_Alignment (Storage_Unit).
28302 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28303 side-effects as if it were a constant; also make SAVE_EXPR to protect
28305 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
28307 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.

28321 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28323 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28324 component of an array of arrays in an assignment context, and the
28325 aggregate has component associations that require sliding on
28326 assignment, force reanalysis of the aggregate to generate a temporary
28327 before the assignment.
28328 (Must_Slide): Make global to the package, for use in Gen_Assign.
28330 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28332 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28333 unchecked union with no inferable discriminants, return a

28336 (Expand_Record_Equality, Component_Equality): Handle properly the case
28337 where some subcomponent is an unchecked union whose generated equality
28338 code raises program error.

28346 Arnaud Charlet <charlet@adacore.com>
28348 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28349 address of the exception registration. The Win32 version of this
28350 routine calls __gnat_install_SEH_handler() to initialize the SEH
28351 (Structured Exception Handling) handler.
28352 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28353 SEH (Structured Exception Handling) now.
28354 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28355 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28356 preprocessor condition protecting the call to the extra eh setup
28357 subprogram, which is only available for the ppc target.
28358 (__gnat_clear_exception_count): replaced reference to
28359 variable taskIdCurrent by call to taskIdSelf(), cleaner.

28364 (GNATBIND_OBJS): Idem.
28366 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28367 routine takes a new parameter (a pointer to the exception registration
28368 for the SEH (Structured Exception Handling) support.
28370 * raise.h: (__gnat_install_SEH_handler): New prototype.
28371 Update copyright notice.
28373 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28374 record and initialize it by calling __gnat_install_SEH_handler.

28401 Remove references to Makefile.prolog/generic, no longer used.
28403 2005-02-09 Vincent Celier <celier@adacore.com>
28405 * prj-makr.adb (Process_Directory): Put file name in canonical case
28406 before matching against the patterns.
28407 If gnatname has been invoked as <prefix>-gnatname
28408 then invoke the compiler as <prefix>-gcc, not just "gcc".
28410 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28412 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28413 with expansion disabled. The actual subtype is needed among other
28414 places when the selected component appears in the context of a loop
28415 bound, and denotes a packed array.
28416 (Operator_Check): Always use the first subtype in the
28417 error message, to avoid the appearance of internal base types.
28418 (Transform_Object_Operation): Copy each actual in full
28419 to the parameter associations of the constructed call, rather than
28420 using the shallow copy mechanism of New_Copy_List. This ensures that
28421 the chaining of named associations is done properly.
28422 (Complete_Object_Operation): Rewrite node, rather than
28423 replacing it, so that we can trace back to the original selected
28426 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28427 and calls that use object notation, if the called function is not
28428 declared in a withed unit, place the elaboration constraint on the
28429 unit in the context that makes the function accessible.
28430 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28431 imposes an elaboration constraint between two packages.
28433 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28435 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28436 views of a private type after handling its private dependents, to
28437 maintain proper stack discipline between entry and exit from the
28440 2005-02-09 Cyrille Comar <comar@adacore.com>

28463 we now use by default.
28465 * xsnames.adb: Adjust end of file test to look for five space followed
28466 by '#' instead of six spaces. The format of xsnames.adb was modified
28467 in the last update.
28469 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28472 * clean.adb: Minor reformatting.
28474 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,

28480 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28483 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28485 2005-02-09 Sergey Rybin <rybin@adacore.com>
28487 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28488 the difference between compact and incompact layout and add the record
28489 representation clause to the example illustrating different layouts.
28490 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28491 component clauses").
28493 2005-02-09 Florian Villoing <villoing@adacore.com>
28495 * gnat_ugn.texi: Fix typos.
28496 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

28545 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28547 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28548 since this procedure is now too complex to be worth inlining.

28801 The current code actually does not check antyhing - this a placeholder
28802 for future refinements.

28847 variable Dynamic_Async.
28848 (Build_Subprogram_Receiving_Stubs): Make PCS-specific

29191 TYPE_SIZE_UNIT of result type if SIZE is not specified.
29192 (make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation

29216 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29217 with an implicit dereference as its prefix, use

29220 prefix is generated, if appropriate.
29222 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29223 dereference is rewritten to an explicit one, generate a reference to
29224 the entity denoted by its prefix using the original prefix node, so

29226 access value, if appropriate.
29228 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29229 emitting 'assigned but never read' warning on a variable on the basis

29243 an external name, to be handled by the back end.
29245 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29246 subprogram which is Imported with convention Intrinsic if an
29247 External_Name argument is specified.
29248 (Process_Import_Or_Interface): Properly diagnose link name argument.

29344 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29345 is a non-overloaded implicit dereference, call the above subprogram to

29411 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29412 internal implementation unit GNAT.Sockets.Thin,
29413 as their usage for sockets is non-portable (using the read and write

29468 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29470 * gigi.h (others_decl, all_others_decl): New decls representing the
29471 new Others_Value and All_Others_Value objects.
29472 (struct attrib): Rename "arg" component as "args", since GCC expects a
29473 list of arguments in there.
29475 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29476 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29479 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29480 others_decl and all_others_decl instead of hardcoded dummy addresses
29481 to represent "others" and "all others" choices, which is cleaner and
29482 more flexible with respect to the possible eh pointer encoding policies.
29484 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29485 (process_attributes): Account for the naming change of the "args"
29486 attribute list entry component.

29489 cumulating attributes for different entities into a single list.
29490 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29491 attributes for the current entity and propagate first subtype
29492 attributes to other subtypes.
29493 <E_Procedure>: Attribute arguments are attr->args and not
29494 attr->arg any more.
29495 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29496 argument provided, as this is what GCC expects. Use NULL_TREE instead

29534 (First_RCI_Subprogram_Id): Document this constant.
29535 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29537 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29538 replaced with calls to Get_Library_Unit_Name_String. Previously there
29539 were several instances of the same code in different locations in the
29540 compiler; this checkin completes the replacement of all of these
29541 instances with calls to a common subprogram.
29542 Minor reformatting.

29576 nodes are improperly shared.
29578 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29579 pragmas to Exp_Prag, which is more appropriate.

29587 Use new Make_String_Literal function with string.
29588 (Get_Stream_Convert_Pragma): New function, replaces the use of
29589 Get_Rep_Pragma, which had to be kludged to work in this case.
29591 * freeze.adb: Use new Has_Rep_Pragma function
29593 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29594 function with string.

29621 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29622 discriminant of a constrained subtype, analyze the copy of the

29627 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29628 handled controlled or secondary-stack expressions within the
29629 iteration_scheme of a loop.
29631 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29632 bounds that may contain functions calls, to prevent memory leaks when
29633 the bound contains a call to a function that uses the secondary stack.
29634 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29635 generate temporaries for loop bounds that might contain function calls
29636 that require secondary stack and/or finalization actions.

29639 selected component and the selector is overloadable (not just a
29640 function) treat as function call, Analyze_Call will disambiguate if

29643 selected component if expansion is disabled. The actual subtype is only
29644 needed for constraint checks.

29646 not permit objects to be declared of a stream type, or of a
29647 composite type containing a stream.

29650 No_Streams no longer prohibits with'ing this package.
29652 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29653 discriminants, but the parent base has unknown discriminants, there is
29654 no discriminant constraint to inherit. Such a discrepancy can arise
29655 when the actual for a formal type with unknown discriminants is a
29656 similar private type whose full view has discriminants.
29657 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29658 do not permit objects to be declared of a stream type, or of a
29659 composite type containing a stream.

29664 protected operations.
29666 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29667 generated name, it complicates decoding in gdb and hinders debugging

29713 procedure Protected_Single_Entry_Call.
29714 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29715 Detect_Blocking which is redundant with the check done within the

29766 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29767 there is no use of GNAT.Sockets.Constants.
29768 Remove remaining pragma Import for C_Write
29769 Remove C_Read and C_Write from internal implementation unit
29770 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29771 the read and write functions from the system runtime library is fine
29772 on UNIX but won't work under Windows).
29774 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29775 (Check_Selector): Use C_Recv instead of C_Read.
29776 Selectors are the GNAT.Sockets abstraction to perform a select()
29777 call on a set of descriptors. To allow abortion of an ongoing
29778 select operation, some data is written to a dedicated socket that
29779 is always monitored.
29780 Under Windows, the write and read library functions cannot operate
29781 on sockets, so we need to use send and recv instead, which is portable
29782 across all supported platforms.
29784 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29785 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29786 (using the read and write functions from the system runtime library is
29787 fine on UNIX but won't work under Windows).
29789 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29791 * mlib-tgt-darwin.adb: New file.
29793 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29794 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29795 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29796 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29799 * Makefile.in: Add support for building shared libraries under Darwin.
29800 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29801 the low level EH init subprogram to be called from __gnat_initialize.
29803 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29804 indicates which options to pass to the archive indexer.
29806 * mlib-utl.adb: Add support for calling ranlib with additional
29807 options. This is needed for instance under Mac OS X.
29808 (Ranlib_Options): New global variable, used to store the potential
29809 options to pass to ranlib.
29810 (Ar): Use Ranlib_Options when spawning ranlib.
29811 (Initialize): Set the value of ranlib option.
29813 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29815 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29816 instead of 8K, to reflect the real potential needs for stack-checking
29819 2004-10-26 Pascal Obry <obry@gnat.com>
29821 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29823 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29824 Windows only the initial thread stack size can be set so it is good to
29825 start we a low stack size.
29826 The OS will adjust the size as needed.
29828 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29829 Nicolas Setton <setton@act-europe.fr>
29831 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29832 "__unix__" instead of "unix".
29833 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29834 sections were just mistakenly ignored. The former is
29835 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29836 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29837 of hpux. This prevents an unwanted definition of the symbol
29838 convert_addresses in adaint.o.
29840 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29842 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29843 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29845 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29847 * a-filico.ads, a-filico.adb: fix incorrect header.
29849 2004-10-26 Javier Miranda <miranda@gnat.com>
29851 * a-ststio.ads: Fix typo in identifier
29853 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29855 * sem_ch4.adb: Minor reformatting.
29857 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29859 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29860 enabled, check the result of unary and binary operations when the
29861 expression is the right-hand side of an assignment.
29863 2004-10-26 Vincent Celier <celier@gnat.com>
29865 * clean.adb (Delete): Do not output warnings when in quiet output and
29866 not in verbose mode.
29867 (Force_Deletions): New Boolean flag, defaulted to False
29868 (Delete): Only delete a file if it is writable, and when
29869 Force_Deletions is True.
29870 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29871 (Usage): Line for new switch -f
29872 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29875 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29877 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29878 JM type only if its size matches that of the wrapper. When a size is
29879 prescribed and the field is not aliased, remove the wrapper of a JM
29880 type only if the size is not greater than that of the packed array.
29881 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29884 2004-10-26 Geert Bosch <bosch@gnat.com>
29886 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29887 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29888 (Pred): Implement in terms of Succ.
29890 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29892 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29893 unchecked conversion is safe for in-place use if the expression of the
29894 conversion is safe.
29895 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29896 be expandable in place even if the aggregate does not come from source.
29897 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29898 designated object of an allocator in place, rather than building it
29899 first on the stack. The previous scheme forces a full copy of the array,
29900 and may be altogether unsusable if the size of the array is too large
29901 for stack allocation.
29903 2004-10-26 Robert Dewar <dewar@gnat.com>
29905 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29906 compares if the component is atomic.
29908 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29909 array assignment if the component type is atomic.
29911 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29912 Eric Botcazou <ebotcazou@act-europe.fr>
29914 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29915 is aliased and is a by_reference type, do not pass by copy.
29916 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29917 detect whether the call is in the right side of an assignment or
29918 the expression of an object declaration. Recurse on component
29919 association within aggregates.
29920 Call it in the condition that determines whether the temporary is
29921 necessary for correct stack-checking.
29923 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29925 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29926 RACW_Type, used in the PolyORB version.
29927 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29928 version and the GARLIC version.
29930 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29931 Rename RCI_Info to RCI_Locator for better consistency between the
29932 GARLIC and PolyORB versions of the distributed systems annex.
29933 (DSA_Implementation_Name): This enumeration lists the possible
29934 implementations of the Partition Communication Subsystem for the
29935 Distributed Systems Annex (DSA). The three available implementations
29936 are the dummy stub implementation (No_DSA), and two versions based on
29937 two different distribution runtime libraries: GARLIC and PolyORB. Both
29938 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29940 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29943 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29944 between the GARLIC and PolyORB versions of the distributed systems
29946 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29948 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29950 * gnat1drv.adb: Suppress calling the back end when
29951 Frontend_Layout_On_Target is true.
29953 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29955 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29956 Set_Read_Only): New subprograms.
29957 These new routines allow the user to set or unset the Owner execute
29958 and Owner write permission flags on a file.
29960 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29961 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29963 2004-10-26 Matthew Gingell <gingell@gnat.com>
29965 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29967 2004-10-26 Pascal Obry <obry@gnat.com>
29969 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29970 memory before the faulting page we properly test the process read
29971 access for this address using appropriate Win32 routine.
29972 (HPUX sections): guard with "__hpux__" instead of "hpux".
29974 2004-10-26 Robert Dewar <dewar@gnat.com>
29976 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29977 entry parameter if pragma Unreferenced set, since we do not properly
29978 handle the case of multiple parameters.
29980 2004-10-26 Vincent Celier <celier@gnat.com>
29982 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29983 (Ada_Objects_Path.Add): For a library project, add to the object path
29984 the library directory only if there is no object directory or if the
29985 library directory contains ALI files.
29986 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29988 2004-10-26 Vincent Celier <celier@gnat.com>
29990 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29991 extension of library projects.
29993 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29994 path defaults to ".:<prefix>/lib/gnat".
29995 (Parse): For an extending all project, allow direct import of a project
29996 that is virtually extended.
29998 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29999 the specified name is directly imported, return its ID. Otherwise, if
30000 an extension of this project is imported, return the ID of the
30003 2004-10-26 Robert Dewar <dewar@gnat.com>
30005 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30006 (Sub3): New procedure, used by Scaled_Divide
30007 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30008 correct more than one instance of failure to propagate carries
30010 (Double_Divide): Handle overflow case of largest negative number
30011 divided by minus one.
30013 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30014 the case of a quotient value out of range.
30017 2004-10-26 Robert Dewar <dewar@gnat.com>
30019 * s-bitops.adb (Bit_Eq): Remove redundant check.
30021 * s-bitops.ads: Minor comment updates
30022 Change some occurrences of Address to System.Address
30024 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30026 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30028 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30029 accessibility check to prefix that is a protected operation.
30031 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30033 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30034 empty, post message on stub.
30036 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30037 Javier Miranda <miranda@gnat.com>
30039 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30040 current instance appears within a unit that is directly in the context
30042 Used to determine whether the body of the instance should be analyzed
30043 immediately after its spec, to make its subprogram bodies available
30044 for front-end inlining.
30045 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30046 constraint is not allowed on the component type (AARM 12.5.3(3))
30048 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30050 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30051 'Storage_Pool): enhance, document & limit detection of non-sharable
30054 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30056 * s-pooglo.ads: Add more documentation now that this pool is properly
30059 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30061 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30062 or protected type with discriminants, do not constrain the
30063 corresponding record type if the subtype declaration has no
30064 discriminant constraints. This can be the case in source code, or in
30065 the subtype declaration created to rename an actual type within an
30068 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30070 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30071 different kind of stub (possibly wrong name for file), do not check
30073 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30074 includes call to some function that returns an unconstrained type, do
30077 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30079 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30080 appear in the code for the main unit. Dependencies among units in the
30081 context of the main unit are established when those other units are
30082 compiled. Otherwise spurious elaboration constraints can generate
30083 incorrect elaboration circularities.
30085 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30086 Ed Schonberg <schonberg@gnat.com>
30088 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30089 subprogram is called with a parameter that is not an object name. This
30090 situation arises for some cases of illegal code, which is diagnosed
30091 later, and in this case it is wrong to call Is_Aliased, as that might
30092 cause a compiler crash.
30093 (Explain_Limited_Type): Refine previous fix to include
30094 inherited components of derived types, to provide complete information.
30096 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30097 is the prival for a protected object.
30098 It is necessary to mark this entity as a variable, in addition to
30099 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30100 modified to avoid checking the Aliased flag on entities that are not
30101 objects. (Checking that flag for non-objects is erroneous and could
30102 lead to a compiler crash).
30104 2004-10-26 Robert Dewar <dewar@gnat.com>
30106 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30107 X_Frac = 0.5, then we know that the number X must be positive.
30108 (Succ): Remove the same redundant test, and also fix the primary test
30109 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30111 (Decompose): Add fuller comments to spec
30113 2004-10-26 Pascal Obry <obry@gnat.com>
30115 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30116 validity (process must have read access). Set to 0 in all other cases.
30117 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30118 violation on Win32.
30119 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30120 segmentation violation.
30122 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30124 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30125 whose type is a constructed subtype of an aliased object with an
30126 unconstrained nominal subtype, convert the actual to the constructed
30127 subtype before taking its address.
30129 2004-10-26 Vincent Celier <celier@gnat.com>
30131 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30132 (Is_Path_Name_Case_Sensitive): New function
30134 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30135 (Base_Name, Simple_Name, Current_Directory, Compose,
30136 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30139 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30140 Vasiliy Fofanov <fofanov@act-europe.fr>
30141 Vincent Celier <celier@gnat.com>
30143 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30144 "memory management issues" section and document some of the useful
30145 memory pools provided as part of the GNAT library.
30146 Remove "virtual" from declaration of A::method2 in
30147 the simple example of Ada/C++ mixed system.
30148 Library Projects may be virtually extended: their virtual extensions
30149 are not Library Projects.
30150 Added section on extending project hierarchies.
30152 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30154 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30156 (__gnat_portable_spawn): Remove const.
30158 * mingw32.h (MAXPATHLEN): Check for previous definition.
30160 2004-10-17 Matthias Klose <doko@debian.org>
30162 * gnatvsn.ads: Set gnat library version to 4.0.
30164 2004-10-05 Vincent Celier <celier@gnat.com>
30166 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30168 2004-10-04 Laurent Guerby <laurent@guerby.net>
30171 * Makefile.in: Define and use RANLIB_FLAGS.
30173 2004-10-04 Pascal Obry <obry@gnat.com>
30175 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30176 other x86 platforms).
30178 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30180 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30181 in general and triggers stack alignment adjustment for thread entry
30182 points on targets where this is necessary.
30184 2004-10-04 Bernard Banner <banner@gnat.com>
30187 * Makefile.in: Add section for powerpc linux
30188 Add variant i-vxwork-x86.ads
30190 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30192 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30194 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30195 table registration calls when need be. Ensures no reference to the crt
30196 ctors symbol are issued in the SJLJ case, which avoids possible
30197 undefined symbol errors in the case of modules to be statically linked
30200 2004-10-04 Javier Miranda <miranda@gnat.com>
30202 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30203 in-line the code corresponding to subprogram Analyze_Actuals. In
30204 addition, analyze the actuals only in case of subprogram call.
30206 2004-10-04 Ed Falis <falis@gnat.com>
30208 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30210 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30212 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30213 in the documentation.
30215 2004-10-04 Robert Dewar <dewar@gnat.com>
30217 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30219 (Analyze_Block_Statement): Add circuitry to detect following dead code
30220 (Check_Unreachable_Code): Handle case of block exit
30222 2004-10-04 Robert Dewar <dewar@gnat.com>
30224 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30225 (XMatchD): Avoid warning for Logic_Error call
30227 2004-10-04 Robert Dewar <dewar@gnat.com>
30229 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30230 consider expressions buried within a procedure actual to be an actual.
30231 This caused some blowups with uses of packed slices within a procedure
30234 2004-10-04 Robert Dewar <dewar@gnat.com>
30236 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30237 longer need to be initialized to zero.
30238 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30239 initialized to zero.
30241 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30242 considered valid, even if the representation is modular. That's correct
30243 now that we no longer initialize packed modular arrays to zero.
30245 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30246 suffixes. These are now documented as the only cases in which the
30247 debugger ignores outer records.
30248 Previously, the spec allowed arbitrary suffixes for this purpose.
30249 Change name of LJM to JM for packed array pad records
30250 Create separate section on packed array handling, and add a whole new
30251 set of comments to this section describing the situation with packed
30252 modular types and justification requirements depending on endianness.
30254 2004-10-04 Robert Dewar <dewar@gnat.com>
30256 * a-except.adb: Add a comment for last change
30258 * einfo.ads: Minor spelling correction in comment
30260 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30262 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30265 * sem_util.ads: Minor comment update
30267 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30269 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30270 Inline_Always when in Configurable_Run_Time mode.
30272 * sem_prag.adb (Process_Convention): If entity is an inherited
30273 subprogram, apply convention to parent subprogram if in same scope.
30274 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30275 when in Configurable_Run_Time mode.
30277 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30279 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30280 class_wide type after component list has been inherited.
30282 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30284 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30285 Denotes_Previous_Actual, to handle properly the case of a private
30286 actual that is also the component type of a subsequent array actual.
30287 The visibility status of the first actual is not affected when the
30288 second is installed.
30289 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30290 make fully recursive the treatment of formals of packages declared
30292 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30293 the above on exit from an instantiation.
30294 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30295 current instantiation which is now complete.
30296 (Analyze_Package_Instantiation): No instantiated body is needed if the
30297 main unit is generic. Efficient, and avoid anomalies when a instance
30298 appears in a package accessed through rtsfind.
30300 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30302 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30303 do not generate a declaration for a temporary if the call is part of a
30304 library-level instantiation.
30306 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30308 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30309 searching for a limited component to flag.
30311 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30312 expansion of Input, to account for the fact that the implicit call
30313 generated by the attribute reference must freeze the user-defined
30314 stream subprogram. This is only relevant to 'Input, because it can
30315 appear in an object declaration, prior to the body of the subprogram.
30317 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30318 expansion can proceed and further errors uncovered.
30319 (Minor clean up): Fix cases of using | instead of \ for continuation
30322 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30324 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30326 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30327 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30328 Use gcc_assert and gcc_unreachable.
30330 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30331 specified alignment before validating size.
30332 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30333 stripped-down declaration for the type of the inner field when making
30336 * utils.c (finish_record_type): Do not compute the size in units
30337 incrementally. Instead compute it once for the rep clause case.
30338 Use gcc_assert and gcc_unreachable.
30340 2004-10-04 Vincent Celier <celier@gnat.com>
30342 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30344 (Is_Valid_Path_Name): Take '/' as a directory separator.
30346 2004-10-04 Vincent Celier <celier@gnat.com>
30348 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30349 (Extended_Project) only if Extended_Project is defined, to avoid
30351 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30353 (Parse_Single_Project): Ditto.
30355 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30356 Add_To_Project_Path for virtual projects.
30358 2004-10-04 Vincent Celier <celier@gnat.com>
30360 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

30363 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30364 parameter Options_2.
30366 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30367 Build_Dynamic_Library with an empty Options_2.
30369 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30372 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30373 directory separator, if any.
30374 (Gprmake): Do not allow mains on the command line for library projects.
30375 Do not attempt to link when the project is a library project.
30376 (Library_Opts): New table to store Library_Options.
30377 (Build_Library): If Library_Options is specified, pass these options
30378 when building a shared library.
30380 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30382 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30383 the end of this procedure now that the unlock operation was inserted
30386 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30388 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30389 corresponding to the Preallocated_Stacks flags in System.
30390 (Get_Target_Parameters): Including the processing for
30391 Preallocated_Stacks.
30393 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,

30399 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
30400 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
30401 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
30402 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30403 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30404 used to signal whether the compiler creates the required stacks and
30405 descriptors for the different tasks (when True) or it is done by the
30406 underlying operating system at run time (when False).
30407 It is initially set to False in all targets.
30409 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30410 if it is supported by the target.
30411 (Make_Task_Create_Call): Pass the stack address if it has been
30412 previously created. Otherwise pass a Null_Address.
30414 * snames.adb: Add _stack.
30416 * snames.ads: Add Name_uStack. Required to allow the expander to
30417 statically allocated task stacks.
30419 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30420 Stack_Address argument.
30421 Check that its value is equal to Null_Address because this target does
30422 not support the static stack allocation.
30424 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30426 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30429 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30431 * exp_dist.adb: Split declaration of asynchronous flag out of
30432 Add_RACW_Read_Attribute.
30433 Minor reformatting for better alignment with PolyORB version.
30434 Store the entity for the asynchronous flag of an RACW, rather than the
30435 expression, in the asynchronous flags table. This will allow this flag
30436 to be used in other subprograms beside Add_RACW_Read_Attribute.
30438 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30440 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
30441 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
30442 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
30443 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
30444 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30445 sockets constant MSG_NOSIGNAL (Linux-specific).
30446 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30447 all Send operations.
30448 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30449 from trigerring SIGPIPE.
30450 Rename components to avoid clash with Ada 2005 possible reserved
30452 (Check_Selector): When the select system call returns with an error
30453 condition, propagate Socket_Error to the caller.
30455 2004-10-01 Jan Hubicka <jh@suse.cz>
30457 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
30459 2004-09-23 Robert Dewar <dewar@gnat.com>
30462 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
30463 instead do this at freeze time (we won't do it if there is an address
30465 Change "pragma inline" to "pragma Inline" in information and error
30467 Minor reformatting.
30469 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30470 right way of doing things after all.
30471 (Freeze_Entity): For object, set Is_Public for imported entities
30472 unless there is an address clause present.
30474 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30476 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30477 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30478 ensures proper handling of types with rep clauses, which might have
30479 their TYPE_SIZE set already.
30481 2004-09-21 Robert Dewar <dewar@gnat.com>
30483 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30484 packed array types in both little- and big-endian cases. This change
30485 ensures that we no longer count on the unused bits being initialized
30486 for such types (and in particular ensures that equality testing will
30487 only read the relevant bits).
30488 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30489 These changes mean that we no longer need to initialize small packed
30491 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30492 optimization to an LJM field as to its parent field.
30494 * ada-tree.h, trans.c, utils.c, utils2.c:
30495 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30497 2004-09-20 Jan Hubicka <jh@suse.cz>
30499 * utils.c (gnat_finalize): Remove.
30500 (end_subprog_body): Directly call cgraph_finalize_function;
30501 do not lower the nested functions.
30503 2004-09-20 Robert Dewar <dewar@gnat.com>
30506 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30507 if an address clause is present, since that means that the Import
30510 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30512 * 5tsystem.ads: Removed, no longer used.
30514 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30515 Zack Weinberg <zack@codesourcery.com>
30517 * ada-tree.def: Use tree_code_class enumeration constants
30518 instead of code letters.
30519 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
30520 Update for new tree-class enumeration constants.
30522 2004-09-17 Vincent Celier <celier@gnat.com>
30524 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private

30531 not initialized warnings.
30533 * a-direct.adb (Current_Directory): Remove directory separator at the
30535 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
30536 an existing directory.
30537 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30538 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30539 Convert the result to File_Size.
30541 * prj.ads: (Project_Error): New exception
30543 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30544 Prj.Com, not from Osint.
30545 (Attrs, Package_Attributes): Tables moved to private part of spec
30546 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30548 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30549 Prj.Project_Error after call to Fail.
30550 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30551 Fail. Check that package name is not already in use.
30553 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30554 used by tools, not only by the project manager, and to indicate that
30555 exception Prj.Prj_Error may be raised in case of problem.
30556 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30558 (Attrs, Package_Attributes): Table instantiations moved from the body to
30559 the private part to be accessible from Prj.Attr.PM body.
30561 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30562 from new package Prj.Attr.PM.
30563 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30566 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
30568 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
30569 instead of Elaboration_Checks).
30571 * a-calend.adb: Minor reformatting
30573 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30575 * gigi.h (maybe_pad_type): New declaration.

30582 * decl.c (maybe_pad_type): No longer static.
30583 (gnat_to_gnu_entity, case E_Function): Handle case of returning by
30585 Convert to use buildN.
30587 * trans.c (call_to_gnu): Add arg GNU_TARGET; support

30599 * utils.c (create_subprog_type): New operand RETURNS_BY_TARGET_PTR.
30600 (create_var_decl): Refine when TREE_STATIC is set.
30601 Convert to use buildN.
30603 2004-09-09 Gary Dismukes <dismukes@gnat.com>

30608 * a-except.adb (Rcheck_*): Add pragmas No_Return for each of these
30611 2004-09-09 Jose Ruiz <ruiz@act-europe.fr>
30613 * gnat_ugn.texi: Add Detect_Blocking to the list of configuration
30614 pragmas recognized by GNAT.
30616 * gnat_rm.texi: Document pragma Detect_Blocking.
30618 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
30619 raise Program_Error if called from a protected operation.
30621 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30622 the protected action nesting level.
30623 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30624 protected action nesting level.
30625 (Unlock): When pragma Detect_Blocking is active decrease the protected
30626 action nesting level.
30628 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30629 Protected_Action_Nesting.
30631 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30632 Common_ATCB record. It contains the dynamic level of protected action
30633 nesting for each task. It is needed for checking whether potentially
30634 blocking operations are called from protected operations.
30635 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30636 Detect_Blocking is active or not in the partition.
30638 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
30639 raise Program_Error if called from a protected operation.
30640 (Task_Entry_Call): When pragma Detect_Blocking is active, raise
30641 Program_Error if called from a protected operation.
30642 (Timed_Task_Entry_Call): When pragma Detect_Blocking is active, raise
30643 Program_Error if called from a protected operation.
30645 * s-tassta.adb (Abort_Tasks): When pragma Detect_Blocking is active,

30648 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
30649 raise Program_Error if called from a protected operation, and increase
30650 the protected action nesting level.
30651 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
30652 Program_Error if called from a protected operation, and increase the
30653 protected action nesting level.
30654 (Unlock_Entries): When pragma Detect_Blocking is active decrease the
30655 protected action nesting level.
30657 * s-tposen.adb (Lock_Entry): When pragma Detect_Blocking is active,
30658 raise Program_Error if called from a protected operation, and increase
30659 the protected action nesting level.
30660 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
30661 Program_Error if called from a protected operation, and increase the
30662 protected action nesting level.

30666 active, raise Program_Error if called from a protected operation.
30667 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
30668 protected action nesting level.
30670 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30671 insertion of the statement raising Program_Error. The run time
30672 contains the required machinery for handling that.
30674 * sem_util.ads: Change comment associated to procedure
30675 Check_Potentially_Blocking_Operation.
30676 This procedure does not insert a call for raising the exception because
30677 that is currently done by the run time.
30679 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30681 * init.c: Add the global variable __gl_detect_blocking that indicates
30682 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30683 making the pragma available at run time.
30684 (__gnat_set_globals): Pass and update the detect_blocking parameter.
30686 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
30687 pragma Detect_Blocking is active.
30689 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30691 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30692 DB is found in the ali file. Any unit compiled with pragma
30693 Detect_Blocking active forces its effect in the whole partition.
30695 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30696 Detect_Blocking is active and delay is called from a protected
30699 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30700 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30701 Detect_Blocking is active (0 otherwise).
30702 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30703 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
30706 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
30708 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30709 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30712 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30713 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30714 Update API in placeholder implemetation of s-parint to reflect changes
30715 in distribution runtime library.
30717 * sem_ch3.adb (Expand_Derived_Record): Rename to
30718 Expand_Record_Extension.
30720 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30721 primitive operations of potentially distributed object types that have
30722 non-controlling anonymous access formals.
30724 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30726 New implementation of expansion for remote access-to-subprogram types,
30727 based on the RACW infrastructure.
30728 This version of sem_dist is compatible with PolyORB/DSA as well as
30731 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30732 Asynchrronous that applies to a remote access-to-subprogram type, mark
30733 the underlying RACW type as asynchronous.
30735 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30736 __gnat_using_gnu_linker to 1.
30738 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30739 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
30740 GNAT.Perfect_Hash_Generators, and remove the empty
30741 GNAT.Perfect_Hash package.
30743 * atree.adb: Minor reformatting
30745 * exp_ch3.adb (Expand_Derived_Record): Rename to
30746 Expand_Record_Extension.
30747 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30748 a component declaration must remain attached at that point in the
30749 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30750 It is therefore necessary to take a copy of the expression when building
30751 the corresponding assignment statement in the init proc.
30752 As a side effect, in the case of a derived record type, we now see the

30958 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
30959 target names rewrite to fix regressions with recent version of

31013 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
31014 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared

31038 for a global aliased object with a variable size and an unconstrained
31039 nominal subtype, pretend there is no initializer if the one we have is
31040 incomplete, and avoid referencing an inexistant component in there. The
31041 part we have will be rebuilt anyway and the reference may confuse

31064 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
31065 unit, this is an attempt to inline a construct that is not available in
31066 the current restricted mode, so abort rather than trying to continue.
31068 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
31069 discriminants that rename those of the parent, recover names of
31070 original discriminants for the constraint on the full view of the

31073 subtype is an itype.
31075 * gnat_rm.texi: Added section on implementation of discriminated

31101 returning C.int, to avoid using a derived boolean type.
31103 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

31132 ignore overflows on low and high bounds of an index to also account for
31133 differences in signedness between sizetype and gnu_index_subtype.
31134 These are as legitimate as the ones caused by a lower TYPE_PRECISION

33761 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33762 overriding, use the operation of the parent unconditionally.
33764 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33765 operation when either operand is a literal, to avoid further
33768 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and

35315 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35316 executable name when not initialized. Otherwise, use its current value.
35318 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35319 initialize it to another executable name than the current one. This
35320 allows to configure paths for an executable name (gnatmake) different
35321 from the current one (gnatdist).
35323 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35325 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35326 current unit cannot be inlined if it appears in the body of a withed
35327 unit, to avoid order of elaboration problems in gigi.
35329 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35330 information for protected (wrapper) operation as well, to simplify gdb
35333 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35334 protected body, indicate that the entity for the generated spec comes
35335 from source, to ensure that references are properly generated for it.

35370 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35372 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35373 attribute reference does not denote a subtype, it can be any
35374 expression that has a classwide type, potentially after an implicit
35375 dereference. In particular, the prefix can be a view conversion for
35376 a classwide type (for which Is_Object_Reference holds), but it can
35377 also be a value conversion for an access-to-classwide type. In the
35378 latter case, there is an implicit dereference, and the original node
35379 for the prefix does not verify Is_Object_Reference.
35381 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35382 conversion of a discriminant-dependent component of a mutable object
35385 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35387 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35388 inherited, has convention C, and has unconstrained array parameters,
35389 place the corresponding warning on the derived type declaration rather
35390 than the original subprogram.

35397 determine whether to generate an implicit or explicit reference to
35398 the renamed entity.

35406 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35407 value expressions to ensure that calls within a component definition
35408 will be checked (since those are evaluated during the record type's

35460 declaration for a child subprogram body that acts as a spec, indicate
35461 that the entity in the declaration needs debugging information.
35463 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35464 full view if the subtype is created for a constrained record component;
35465 gigi has enough information to construct the record, and there is no
35466 place in the tree for the declaration.
35468 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35469 serial number for the dummy body that is built for analysis, to avoid
35470 inconsistencies in the generation of internal names when compiling

35506 * ada-tree.h: Update copyright notice.
35507 Minor reformatting.
35509 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35511 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35512 as regular exception objects and not as mere integers representing the
35513 condition code. The latter approach required some dynamics to mask off
35514 severity bits, which did not fit well into the GCC table based model.
35515 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35516 exception data objects. We don't it and it would conflict with the other
35517 external symbol we have to generate for such exceptions.
35519 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35520 the special code for VMS exceptions, since these are now represented
35521 as regular exceptions objects.
35523 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35525 * decl.c (debug_no_type_hash): Remove.

35564 When needed (stack checking) the stack size is retrieved
35565 from the VxWorks kernel.
35567 * Makefile.in: Flag -nostdinc is required when building the run time
35568 for avoiding looking for files in the base compiler.
35569 Add the VxWorks specific version of the package body for
35570 System.Stack_checking.Operations (5zstchop.adb).
35572 * Make-lang.in: Add the object file for
35573 System.Stack_Checking.Operations.

35598 the procedures Add_To_Path_File.
35599 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35600 making sure that each directory is present only once and, for object
35601 dirs, when a directory already present is added, the duplicate is
35602 removed and the directory is always put as the last in the table.
35603 Write the path files at the end of these accumulations.

35699 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35700 component of Standard_Exception_Type to be the closest possible to
35701 Exception_Code in System.Standard_Library, that we cannot get at this

35815 explicit dereference.
35816 (Expand_N_Slice): Same. Always do the rewriting, even for the case
35817 of non-packed slices, since the dereference action generated by
35818 expansion of the explicit dereference is needed in any case.

35820 analyze and resolve the rewritten explicit dereference so it is seen
35822 (Insert_Dereference_Action): This procedure is now called only for the
35823 expansion of an N_Explcit_Dereference_Node. Do insert a check even for

36664 No_Requeue_Statements.
36666 * s-rident.ads: Adding restriction No_Requeue_Statements (AI-00249)

36668 kept for backward compatibility.
36670 2004-02-02 Ed Schonberg <schonberg@gnat.com>
36672 * lib.ads, i-cobol.ads, * s-stoele.ads, s-thread.ads, style.ads,

36699 * utils.c (create_field_decl): Augment the head comment about bitfield
36700 creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
36701 here, because the former is not accurate enough at this point.
36702 Let finish_record_type decide instead.
36703 Don't make a bitfield if the field is to be addressable.
36704 Always set a size for the field if the record is packed, to ensure the
36705 checks for bitfield creation are triggered.
36706 (finish_record_type): During last pass over the fields, clear
36707 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
36708 not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P
36709 from DECL_BIT_FIELD.

37166 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37167 N_String_Literal node always references an E_String_Literal_Subtype
37168 entity. This may not be true in the future.
37169 (Possible_Bit_Aligned_Component): Move processing of
37170 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37172 * exp_ch6.adb (Expand_Thread_Body): Pick up
37173 Default_Secondary_Stack_Size as variable so that we get value modified
37174 by possible -Dnnn binder parameter.
37176 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37177 (Type_May_Have_Bit_Aligned_Components): New function.

37217 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37218 ineffective elaborate all pragmas on non-visible packages (this
37219 happened when a renamed subprogram was called). Now the elaborate all
37220 always goes on the package containing the renaming rather than the one
37221 containing the renamed subprogram.
37223 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37224 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37479 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37480 bounds of a loop, create a separate block in order to generate proper
37481 cleanup actions to prevent memory leaks.
37483 * sem_res.adb (Resolve_Call): After a call to
37484 Establish_Transient_Scope, the call may be rewritten and relocated, in

37503 2003-12-08 Robert Dewar <dewar@gnat.com>
37505 * 7sintman.adb: Minor reformatting
37507 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37508 standard linker options to get standard libraries linked. We now plan
37509 to provide dummy versions of these libraries to match the appropriate
37510 configurable run-time (e.g. if a library is not needed at all, provide
37511 a dummy empty library).
37513 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37514 options (-L parameters and standard libraries). What we plan to do is
37515 to provide dummy libraries where the libraries are not required.
37517 * gnatbind.adb: Minor comment improvement
37519 2003-12-08 Javier Miranda <miranda@gnat.com>
37521 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

37529 of aggregate with default initialized components.
37530 (Has_Default_Init_Comps): Improve implementation to recursively check
37531 all the present expressions.
37533 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37534 to indicate that the initialization call corresponds to a
37535 default-initialized component of an aggregate.
37536 In case of default initialized aggregate with tasks this parameter is
37537 used to generate a null string (this is just a workaround that must be
37538 improved later). In case of discriminants, this parameter is used to
37539 generate a selected component node that gives access to the discriminant
37542 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37543 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37544 allocated aggregates with default-initialized components.
37546 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37547 the box notation is used in positional aggregates.

37589 Process nodes N_Comment.
37591 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37592 without comments and there are some comments, set the flag
37593 Unkept_Comments to True.
37594 (Scan): If there are comments, set the flag Unkept_Comments to True and
37595 clear the comments.
37596 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
37597 (Next_End_Nodes: New table

37625 Comment_Id and set Token to Tok_Comment when scanning a comment.
37626 (Set_Comment_As_Token): New procedure
37628 * sinput-p.adb: Update Copyright notice
37629 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

37635 Correct typo in comment
37636 (Resolve_Aggregate): In case of array aggregates set the estimated
37637 type of the aggregate before calling resolve. This is needed to know
37638 the name of the corresponding IP in case of limited array aggregates.
37639 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37640 in case of default initialized array components.
37642 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

37685 unwind past it. Update the copyright notice.
37687 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37689 * a-elchha.ads: New file.

39143 Remove the test against being in No_Run_Time_Mode before generating a
39144 call to Register_Tag. It is redundant with the test against the
39145 availability of the function Register_Tag.

41350 * gnat-style.texi (header): Add @dircategory, @direntry.
41351 (title page): Remove date.
41352 (general) Add @./@: where approriate, and two spaces after the
41353 full stop at the end of a sentence. Use @samp markup when
41354 referring concrete lexical entities (keywords, attribute names
41355 etc.), and @syntax for ARM grammar elements. Use @r for English

41370 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41371 function approach did not work well because of a side effect (the
41372 function call could reallocate the table which was being indexed
41373 using its result). Fixes ada/4851.

41411 * raise.c (__gnat_eh_personality): Exception handling personality
41412 routine for Ada. Still in rough state, inspired from the C++ version
41413 and still containing a bunch of debugging artifacts.
41414 (parse_lsda_header, get_ttype_entry): Local (static) helpers, also
41415 inspired from the C++ library.
41417 * raise.c (eh_personality): Add comments. Part of work for the GCC 3
41418 exception handling integration.

41431 * a-ngelfu.adb: Remove ??? comment for inappropriate Inline_Always
41432 Add 2001 to copyright date
41434 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
41435 need to force universal inlining for these cases.
41437 2001-12-19 Arnaud Charlet <charlet@gnat.com>
41439 * s-taprob.adb: Minor clean ups so that this unit can be used in
41442 * exp_ch7.adb: Allow use of secondary stack in HI mode.
41443 Disallow it when pragma Restrictions (No_Secondary_Stack) is specified.

41465 discriminant check if the selected component is a component of
41466 the argument of an initialization procedure.
41468 * trans.c (tree_transform, case of arithmetic operators): If result
41469 type is private, the gnu_type is the base type of the full view,
41470 given that the full view itself may be a subtype.
41472 2001-12-17 Robert Dewar <dewar@gnat.com>
41474 * sem_res.adb: Minor reformatting
41476 * trans.c (tree_transform, case N_Real_Literal): Add missing third

41740 2001-12-17 Laurent Pautet <pautet@gnat.com>
41743 Fix comment of Shutdown_Socket and Close_Socket. These functions
41744 should not fail silently because if they are called twice, this
41745 probably means that there is a race condition in the user program.
41746 Anyway, this behaviour is consistent with the rest of this unit.
41747 When an error occurs, an exception is raised with the error message
41748 as exception message.

43077 (GNATMAKE_RTL_OBJS): add g-crc32.o
43080 (CRC_Match): new function.
43081 (Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
43082 instead of the previous simple checksum algorithm.
43083 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43084 (Set_Source_Table): idem.
43087 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43088 instead of simple checksum.
43089 (CRC_Match): new function.
43090 (CRC_Error): new constant.
43092 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43093 a CRC now and not a simple checksum. A CRC uses lower-case hex
43094 letters, fixes ambiguity in parsing.
43096 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43097 is what this variable will store.
43099 * bcheck.adb: Change reference to chechsum in comments by CRC.
43100 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43101 rename All_Checksum_Match to All_CRC_Match. Change due to API
43102 renaming since now GNAT does not use a simple checksum but a
43103 CRC using GNAT.CRC32.
43105 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43106 now and not anymore a simple checksum.
43108 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
43111 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
43114 (Restore_Scan_State): rename Checksum to CRC.
43115 (Save_Scan_State): idem.
43119 (Checksum): rename to CRC.
43120 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
43122 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
43123 GNAT.CRC32). Update copyright notice.
43125 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
43126 GNAT.CRC32). Update copyright notice.
43129 (Accumulate_Checksum): removed.
43130 (Update): new procedure. Add a wide-character into the CRC.
43133 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
43134 (Load_File): fix initialization of S (change Source_Checksum to
43137 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
43138 Source_CRC in S initialization.
43140 * sinput.adb (Source_Checksum): renamed to Source_CRC.
43142 * sinput.ads (Source_Checksum): renamed to Source_CRC.
43143 Update comments for the CRC.
43145 * types.adb (Hex): Use lowercase for the letter part.
43147 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43148 for a word. This is currently used only for CRC. In previous version,
43149 the checksum was using a representation with all letter being
43150 upper-case. With the new implementation (using CRC) we do not remove
43151 the 32th bit of the CRC, so we can have an upper-case starting letter
43152 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43153 It is ambigous since the CRC was optional and could be followed by
43154 options like EB, EE. So now this routines uses lower-case letter for
43155 the hexadecimal representation. Strange enough only lower case letters
43156 where checked in Scan_ALI (even if this was not a possible case).
43158 * gnatvsn.ads (Library_Version): changed to 3.15a.
43160 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43163 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
43166 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
43167 Add 2001 to copyright notice
43168 (Accumulate_Checksum): Modify to use System.CRC32.
43170 * ali-util.ads: Redo changes of previous revision to continue to use
43171 the word Checksum. Add 2001 to copyright notice.
43173 * ali.adb: Undo some of previous changes, not needed.
43174 Keep the change for lower case letters in the checksum.
43176 * ali.ads: Undo previous change not needed.
43178 * bcheck.adb: Undo most of previous change, not needed.
