2012 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2013 Orig_Prev to Prev in the case where the actual is N_Function_Call or

4108 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4109 convention from its base type, do not set the type to that of integer,
4110 because it may inherit a size clause.

4176 New local subprogram Is_Valid_Remote_Object_Type, replaces
4177 Is_Recursively_Limited_Private.

4188 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4189 Is_Remote_Call_Interface to identify RACW types in a stable and
4190 consistent way. We used to rely in this predicate on the privateness of
4191 the designated type and its ancestors, but depending on the currently
4192 visible private parts, this caused false negatives. We now uniformly
4193 rely on checks made at the point where the RACW type is declared.

4207 Add missing escaping of all-caps word 'CPP' in error messages.
4208 (Build_Discriminated_Subtype): Do not inherit representation clauses
4209 from parent type if subtype already carries them, because they are
4210 inherited earlier during derivation and already include those that may
4211 come from a partial view.
4213 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4214 Check the declarations of a subprogram body for proper deferred

4249 operation of an RACW stub type (these primitives are only executed
4250 through dispatching, never through static calls).
4251 (Collect_Interps): When only one interpretation has been found, set N's
4252 Entity and Etype to that interpretation, otherwise Entity and Etype may
4253 still refer to an interpretation that was ignored by Add_One_Interp,
4254 in which case would end up with being marked as not overloaded but with
4255 an Entity attribute not pointing to its (unique) correct interpretation.

4270 (Print_Itype): Do not modify the sloc of the component type of a

8515 WITH clause on a private sibling.
8516 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8517 child unit is a renaming, create an implicit with_clause on that
8518 parent, and not on the unit it renames, to prevent visibility errors

8585 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
8586 type from a limited_with_clause, and the full view is available, use it

8615 Gary Dismukes <dismukes@adacore.com>
8617 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
8618 requeue statement is dispatching. Do not emit an error when the name is
8619 not an entry and the context is a dispatching select. Add code to
8620 perform subtype conformance between the formals of the current entry
8621 and those of the target interface primitive.
8622 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8623 Timed_Entry_Call): Analyze the triggering statement as the first step of
8624 the processing. If this is a dispatching select, postpone the analysis
8625 of all select statements until the Expander transforms the select. This
8626 approach avoids generating duplicate identifiers after the Expander has
8627 replicated some of the select statements. In case the Expander is
8628 disabled, perform regular analysis.
8629 (Check_Triggering_Statement): New routine.
8630 (Analyze_Requeue): Exclude any interpretations that are not entries when
8631 checking overloaded names in a requeue. Also test type conformance for
8632 matching interpretations rather than requiring subtype conformance at
8633 that point to conform with the RM's resolution rule for requeues.

8637 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
8638 inherited operation is a defaulted tag-indeterminate call, and there is
8639 a statically tagged actual, use the static tag as a controlling actual
8640 for the defaulted actual.
8642 2007-12-13 Geert Bosch <bosch@adacore.com>
8644 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

9227 multiple inherited interfaces info. This information cannot be stored
9228 in Xref_Entity_Record, which only supports a single instance of Tref_*,

9245 additional management on these nodes in Expand_Interface_Actuals.
9247 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9248 that handles use of 'Access and 'Unchecked_Access applied to

9294 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9295 used by VxWorks targets to have access to task-specific data and be
9296 able to extract the stack boundaries for stack checking.

9340 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9341 association for an access component, add an association with null as
9342 the expression. Remove testing for array subtypes and the setting in
9343 that case of Ctyp to the array component type, which prevented proper
9344 inclusion of an association for null-initialized arrays. Collapse
9345 condition that tests for array subtypes into just a test of
9346 Is_Partially_Initialized_Type (which already covers arrays anyway).

9363 * sem_ch4.adb: Minor code and comment reformatting.
9364 (Analyze_Allocator): When the designated type of an unconstrained

9496 (gigi): Rename and change type of number_units parameter, change
9497 type of file_info_ptr parameter.
9498 * trans.c (number_files): New global variable.
9499 (gigi): Rename and change type of number_units parameter, change
9500 type of file_info_ptr parameter.
9501 If mapped location support is enabled, create the isomorphic mapping
9502 between source files and line maps.
9503 (Sloc_to_locus): If mapped location support is enabled, translate
9504 source location into mapped location.
9505 (annotate_with_node): Rename into set_expr_location_from_node.

9531 * a-calend-vms.adb, a-calend.adb:
9532 Add a section on leap seconds control along with two entities used to
9533 enable and disable leap seconds support. The array Leap_Second_Times is
9534 now constant and contains hard time values pre-generated. Remove
9535 all elaboration code used to populate the table of leap seconds.
9538 Add entity Leap_Seconds_Support to the list of global run-time variables
9539 along with a comment on its usage and values.
9540 (Gen_Adainit_Ada): Add code to generate the declaration and import of

9554 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
9555 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
9557 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
9559 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
9560 function which can be called by the debugger to interrupt the tasks of
9561 an Ada application asynchronously, as needed on VxWorks.

9575 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
9576 #include <sys/wait.h>.
9578 2007-09-26 Thomas Quinot <quinot@adacore.com>

9595 2007-09-26 Javier Miranda <miranda@adacore.com>
9596 Eric Botcazou <ebotcazou@adacore.com>
9599 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9600 indirection added to the HT_Link component of the TSD. This is required
9601 to statically allocate the TSD.
9604 Minor reordering of the declarations in the private part. Required to
9605 add a level of indirection to the contents of the TSD component HT_Link.
9606 This is required to statically allocate the TSD.
9608 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9609 Is_Statically_Allocated set from constant objects.
9610 Do not make exported constants created by the compiler volatile.
9611 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9614 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9615 before returning them.
9617 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9618 public part of the package.
9619 (Make_DT): Move HT_Link component out of the TSD record. For this
9620 purpose Make_DT now declares a separate object that stores the
9621 HT_Link value, and initializes the TSD component with the address
9622 of this new object. The addition of this level of indirection is
9623 required to statically allocate the TSD because the TSD cannot
9624 have variable components.
9625 (Expand_Interface_Conversion): Improve the expanded code.
9626 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9628 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9629 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9630 if we are building static dispatch tables then we must not generate
9631 extra code to register the primitive because the dispatch table will
9632 be built at the end of the library package; otherwise we notify that
9633 we cannot build the static dispatch table.
9635 2007-09-26 Robert Dewar <dewar@adacore.com>
9637 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
9640 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
9641 (Analyze_Record_Representation_Clause): Suppress junk warning for
9642 missing component clause.

9644 tests for controlled type overlay to composites with controlled
9646 (Analyze_Record_Representation_Clause): Add reference for component name

9652 for thunks associated with interface types.
9654 * einfo.ads: Improve documentatation of Is_Internal
9655 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9656 associated with interface types.
9657 Extensive comment fixes regarding flags that appear in all entities. The
9658 documentation is now consistent for all such flags (there were a number
9659 of errors in the documentation in this regard).
9661 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9663 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9664 of these procedures are passed a function call that already has
9665 build-in-place actuals (testing new flag
9666 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9667 the case where processing continues.
9668 (Expand_Call): If the call is generated from a thunk body then we
9669 propagate the extra actuals associated with the accessibility
9670 level of the access type actuals.
9672 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9673 of each extra formal of a protected operation to reference the
9674 corresponding extra formal of the subprogram denoted by the
9675 operation's Protected_Body_Subprogram.
9677 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9678 N_Function_Call nodes.
9680 2007-09-26 Robert Dewar <dewar@adacore.com>
9682 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9684 * debug.adb: Add d.s flag.
9686 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9688 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9689 debug variable so that it won't be initialized when pragma
9690 Initialize_Scalars is in effect.
9692 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9694 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9695 initialization of a full view. This is moved to
9696 Analyze_Package_Specification.
9698 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9699 preelaborable initialization of a full view in entity loop.
9700 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9701 its child units are use-visible only if they are visible child units.
9703 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9704 whether an expression can be used within a type declaration that
9705 requires preelaborable init.
9706 (Check_Components): Replace inline code that does partial checking for
9707 preelaborable default expressions with call to
9708 Is_Preelaborable_Expression.
9709 (Has_Preelaborable_Initialization): In the case of a generic actual
9710 subtype, (that is, Is_Generic_Actual is True), return the result of
9711 applying Has_Preelaborable_Initialization to the generic actual's base
9714 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9716 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9717 call to Jan_1_Day _Of_Week to optimize its performance.
9718 (Is_Leap): Move the routine to the scope of Week_In_Year.
9719 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9720 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9721 avoids calling Time_Of and Split, thus making it more efficent.
9722 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9724 * g-calend.ads (Week_In_Year): Change comment to reflect new
9727 2007-09-26 Emmanuel Briot <briot@adacore.com>
9729 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9730 Command_Line): New types
9731 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9732 support for defining how switches can be grouped on a command line (as
9733 is the case for -gnatw... for GNAT), and how simple switches can be
9734 used as aliases for more complex switches (-gnatwa is same as
9736 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9737 (Start, Current_*): New subprograms
9738 Added support for parsing an array of strings in addition to the real
9740 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9741 be moved from the body to the private part of the spec.
9742 (*): All subprograms now have an extra parameter with default value to
9743 specify which parser should be used. For backward compatibility, it
9744 defaults to parsing the command line of the application. They were also
9745 modified to properly handle cases where each of the argument does not
9746 start at index 1 (which is always true for Ada.Command_Line, but not
9747 when processing any Argument_List).
9748 (Free): New subprogram
9749 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9750 Argument): New subprograms
9751 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9752 special characters like ':', '=',... are now handled in a single place,
9753 which makes the code more extensible eventually.
9754 (Getopt, Full_Switch): When the switch was returned as part of the
9755 special character '*', make sure it is prepended by the switch character
9756 ('-' in general), so that the application knows whether "foo" or "-foo"
9757 was specified on the command line.
9759 2007-09-26 Florian Villoing <villoing@adacore.com>
9761 * g-dirope.adb (Remove_Dir): In case we are removing directories
9762 recursively, make sure that if an exception is raised during the
9763 processing, the current working directory is reset to its initial
9764 value before propagating the exception.
9766 2007-09-26 Vincent Celier <celier@adacore.com>
9768 * gnatbind.adb: If there are several ALI files specified and there is
9769 a main program to bind, the first ALI is expected to contain the main
9770 subprogram and the names of the binder generated files will be derived
9771 from the first ALI file name.
9772 (Gnatbind): Fix insertion character in invocation of Error_Msg
9774 2007-09-26 Vincent Celier <celier@adacore.com>
9776 * gnatcmd.adb (Check_Files): Do not include sources that have been
9777 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9779 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9781 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9782 information about each of its index types, following the type
9783 reference for its component type.
9785 2007-09-26 Vincent Celier <celier@adacore.com>
9787 * make.adb: (Kill): New procedure (__gnat_kill imported)

9789 were previously local to procedure Compile_Sources.
9790 (Sigint_Intercepted): Send signal SIGINT to all outstanding
9791 compilation processes.
9793 (Gnatmake): If project files are used, create the mapping of all the
9794 sources, so that the correct paths will be found.
9796 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
9798 2007-09-26 Vincent Celier <celier@adacore.com>
9800 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9802 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9803 Replace components Compiler_Min_Options and Binder_Min_Options with
9804 Compiler_Required_Switches and Binder_Required_Switches in record
9806 Remove components Default_Language and Config in Project_Tree_Data,
9809 * prj-attr.adb: New attributes Required_Switches (<language>) in
9810 packages Compiler and Binder.
9812 * prj-nmsc.adb: Major rewrite of the processing of configuration
9813 attributes for gprbuild. No impact on GNAT tools.
9815 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9816 process configuration attributes: this is done in Prj.Nmsc.Check.

9818 being extended, instead of a shallow copy.
9819 (Process_Project_Tree_Phase_1): New procedure

9821 (Process): Implementation now uses the two new procedures
9823 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9824 from the project config, not the tree config that no longer exists.
9826 2007-09-26 Vincent Celier <celier@adacore.com>

9847 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9849 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
9850 ancestor of the derived type, the operations are inherited from the
9851 primary dispatch table of the parent.
9852 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9853 when the context is an explicit type conversion.
9855 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9857 * sem_ch4.adb (Analyze_Qualified_Expression): Apply name resolution
9858 rule for qualified expressions properly, to detect improper conversions

9899 * makegpr.adb (Link_Executables): Do not fail when the root project has
9900 no sources, but is an extending project.
9902 2007-09-25 Eric Botcazou <ebotcazou@adacore.com>
9904 * trans.c: Fix misplaced #define.
9906 2007-09-22 Eric Botcazou <ebotcazou@adacore.com>
9908 * utils2.c (build_unary_op) <ADDR_EXPR> [INDIRECT_REF]: Propagate

10155 potentially be called.
10156 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10157 body for 'Output when the type is abstract (only the creation of the
10158 body for 'Input is excluded when the type is abstract).

10160 statement, so that False will be returned for TTS_Stream_Input if the
10161 associated tagged type is an abstract extension. Add comments for
10163 (Expand_N_Object_Declaration): For the case of a shared passive
10164 variable, insert init proc call only after the shared variable
10165 procedures have been processed, because the IP call needs to undergo
10166 shared passive variable reference expansion, which requires these
10167 procedures to be available (and elaborated).

10179 type, retrieve its value from the aggregate itself, where it must have
10182 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10183 to remove other spurious ambiguities on arithmetic operations involving
10184 literals and addresses, on systems where Address is a visible integer
10185 type, when the operator is called in functional notation.
10186 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10187 is legal when the types match, even if the operation is currently

10192 * sem_ch12.adb (Build_Local_Package): A formal package with no
10193 associations is legal if all formals have defaults. It is not

10312 (Write_Entity_Flags): Write the status of flag Is_Raised.
10313 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10314 spurious ambiguities when integer literals appear in the context of an
10315 address type that is a visible integer type.
10317 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10318 exceptions never being raised.
10319 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

10333 2007-08-31 Gary Dismukes <dismukes@adacore.com>
10335 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10336 library-level package renaming, pass the declaration associated with
10337 the renaming's special debug variable to Qualify_Entity_Names to ensure
10338 that its encoded name is properly qualified.
10340 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10341 occurring in the list of entities to qualify, and do not attempt to
10342 traverse an entity list in that case. Variables associated with
10343 ` library-level package renamings can now occur in the table.
10345 * exp_dbug.ads: Revise documentation of the encoding for renaming
10348 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

10351 access type points to an unconstrained array.
10353 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10355 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
10358 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect

10367 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10368 concatenations of string literals into a single literal, in order to
10369 avoid very deep recursion in the front end, which was causing stack
10372 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10373 string, and the right operand is a string literal (the case of "" &
10374 "..."), optimize by avoiding copying the right operand -- just use the
10375 value of the right operand directly.
10377 * stringt.adb (Store_String_Chars): Optimize by growing the
10378 String_Chars table all at once, rather than appending characters one by
10380 (Write_String_Table_Entry): If the string to be printed is very long,
10381 just print the first few characters, followed by the length. Otherwise,
10382 doing "pn(n)" in the debugger can take an extremely long time.
10384 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10385 Store_String_Char with Store_String_Chars.

10398 * sem_ch10.adb (Analyze_Subunit_Context): When analyzing context
10399 clauses of subunits, ignore limited_with_clauses that are illegal and
10400 have not been fully analyzed.
10402 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10404 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10405 flag, for effiency. It is called when analyzing arithmetic operators
10406 and also for actuals in calls that are universal_integers. The flag is
10407 set for the predefined type address, and for any type or subtype
10410 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10411 Universal_Integer, when the formal is a descendent of address and the
10412 call appears in user code.
10413 (Analyze_Selected_Component): if the prefix is a private extension, the
10414 tag component is visible.

10477 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10479 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10480 associated with Standard_Debug_Renaming_Type, to be used as the type of
10481 the special variables whose names provide debugger encodings for
10482 renaming declarations.
10484 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10485 (Set_Debug_Renaming_Link): Change to set Node25.

10492 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10493 and literal with creation of a variable of type
10494 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10495 and the entity of the renaming declaration.
10496 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10497 part of the name of a variable that has a Debug_Renaming_Link.
10499 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10500 special type to be associated with variables that provide debugger

10504 Ed Schonberg <schonberg@adacore.com>
10505 Javier Miranda <miranda@adacore.com>
10507 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10508 ancestor part given by an aggregate to test for an unchecked conversion,
10509 since this can occur in some cases when the ancestor part is a function
10510 call, and we don't want to fall into the recursive call to this
10511 procedure in that case.
10513 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10514 stream attributes on limited types to account for user-specified
10515 attributes as well as whether Input (resp. Output) becomes available
10516 due to Read (resp. Write) being available for the type. Change Boolean
10517 variable to the more accurate name
10518 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10519 double-"not" predicate at beginning of return statement to more
10520 understandable form.
10522 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10523 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10524 in a block statement and use that as the first statement of the
10525 expanded return rather than incorrectly using the handled sequence as
10526 the first statement.
10528 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10529 operation, generate an explicit freeze node for it rather than
10530 generating extra formals, to ensure that gigi has the proper order of
10531 elaboration for anonymous subtypes in the signature of the subprograms.
10532 (Build_In_Place_Formal): Move assertion to beginning of loop.
10533 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

10536 applied to a function call (occurs for some cases of 'Input).
10538 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10539 2005, generate an extended return statement enclosing the result object
10542 * freeze.adb (Freeze_Record_Type): Extend the current management of
10543 components that are access type with an allocator as default value: add
10544 missing support to the use of qualified expressions of the
10545 allocator (which also cause freezing of the designated type!)
10546 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10547 dispatching operation, since extra formals may be needed by calls to
10548 build-in-place functions (such as stream 'Input).
10550 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10551 formals for 'Constrained and accessibility level in the case of a
10552 predefined dispatching operation.
10554 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10555 point, no need to find the parent node.
10557 2007-08-16 Javier Miranda <miranda@adacore.com>
10559 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10560 and entry barriers.
10562 2007-08-16 Javier Miranda <miranda@adacore.com>
10564 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10565 is not really required and can introduce regression with the debugger.
10566 The original problem is fixed with the patch written for checks.adb.
10568 2007-08-16 Thomas Quinot <quinot@adacore.com>
10570 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10580 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10581 parameter Including_Non_Switch, defaulted to True. When
10582 Including_Non_Switch is False, options that are not switches and
10583 appear as relative path are not converted to absolute paths.
10585 2007-08-16 Nicolas Roche <roche@adacore.com>
10587 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

10598 from the immediate ancestor of Main_Unit_Entity.
10599 (Install_Limited_Withed_Unit): Do not install the limited view of
10600 package P if P is reachable through an ancestor chain from package C

10603 (Has_With_Clause): New routine.
10605 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10607 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10608 generic for an enclosing instance is a global reference, even though
10609 its scope is the enclosing instance.
10611 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10612 Javier Miranda <miranda@adacore.com>
10614 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to

10622 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
10625 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10627 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10628 implements an operation inherited from a progenitor interface, verify
10629 that they are subtype-conformant.

10632 Bob Duff <duff@adacore.com>
10633 Nicolas Setton <setton@adacore.com>
10635 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10636 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10637 the statement which is being resolved comes from a predefined library
10638 unit, all non-predefined library interpretations are skipped.
10639 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10640 but the "&" is user defined, give an error, because the folding would

10644 the parser has folded a long sequence of concatenations of string
10647 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10648 and "JMP_BUF" variables as artificial.
10649 (N_String_Literal): Do not use alloca for very long string literals. Use

10697 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10698 Suppress unmodified in-out parameter warning in some cases
10699 This patch is a also fairly significant change to the way suppressible
10700 checks are handled.
10702 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10703 needed for access to concurrent record types generated by the expander.
10704 (Generate_Range_Check): When generating a temporary to capture the
10705 value of a conversion that requires a range check, set the type of the
10706 temporary before rewriting the node, so that the type is always
10707 properly placed for back-end use.
10708 (Apply_Float_Conversion_Check): Handle case where the conversion is
10710 (Get_Discriminal): Code reformatting. Climb the scope stack looking

10727 parameters when deciding whether to apply a run-time accessibility
10729 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10730 aggregate code before allocator, and ahead of declaration for
10731 temporary, to prevent access before elaboration when the allocator is
10732 an actual for an access parameter.
10733 (Expand_N_Type_Conversion): On an access type conversion involving an
10734 access parameter, do not apply an accessibility check when the
10735 operand's original node was an attribute other than 'Access. We now
10736 create access conversions for the expansion of 'Unchecked_Access and
10737 'Unrestricted_Access in certain cases and clearly accessibility should
10738 not be checked for those.
10740 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10741 includes a type conversion of a packed component that has been expanded,
10742 recover the original expression for the object, and use this expression
10743 in the post-call assignment statement, so that the assignment is made
10744 to the object and not to a back-end temporary.
10745 (Freeze_Subprogram): In case of primitives of tagged types not defined
10746 at the library level force generation of code to register the primitive
10747 in the dispatch table. In addition some code reorganization has been
10748 done to leave the implementation clear.
10749 (Expand_Call): When expanding an inherited implicit conversion,
10750 preserve the type of the inherited function after the intrinsic
10751 operation has been expanded.
10753 * exp_ch2.ads, exp_ch2.adb
10754 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10755 of an entry formal appearing in an assignment statement does not assign
10757 (Expand_Current_Value): Instead of calling a routine to determine
10758 whether the prefix of an attribute reference should be optimized or
10759 not, prevent the optimization of such prefixes all together.
10761 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10762 component whose prefix is known to be of an access type is an implicit
10763 dereference and does not assign to the prefix.

10766 Robert Dewar <dewar@adacore.com>
10768 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10769 itype is visited, make an entry into table to link associated node and
10771 Add comments and correct harmless error in Build_NCT_Hash_Tables
10772 (Array_Aggr_Subtype): Associate each itype created for an index type to
10773 the corresponding range construct, and not to the aggregate itself. to
10774 maintain a one-to-one correspondence between itype and its associated
10775 node, to prevent errors when complex expression is copied.
10776 Fix mishandling of multiple levels of parens

10779 treatment of limited views uniform for all visible declarations in a
10780 limited_withed package.
10781 (New_Copy_Tree): If hash table is being used and itype is visited,
10782 make an entry into table to link associated node and new itype.
10783 (Resolve_Record_Aggregate): Do not add an others box association for a
10784 discriminated record component that has only discriminants, when there
10785 is a box association for the component itself.
10787 * par-ch4.adb: Fix mishandling of multiple levels of parens
10789 2007-08-14 Robert Dewar <dewar@adacore.com>

10823 Gary Dismukes <dismukes@adacore.com>
10825 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,

10832 Warn on duplicate pragma Preelaborable_Initialialization
10834 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10835 generation of a freezing node to ensure proper management of null
10836 excluding access types in the backend.
10837 (Create_Extra_Formals): Test base type of the formal when checking for
10838 the need to add an extra accessibility-level formal. Pass the entity E
10839 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10840 originally being done in a couple of cases), to ensure that the
10841 Extra_Formals list gets set on the entity E when the first entity is
10843 (Conforming_Types): Add missing calls to Base_Type to the code that
10844 handles anonymous access types. This is required to handle the
10845 general case because Process_Formals builds internal subtype entities
10846 to handle null-excluding access types.
10847 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10848 functions that need it, even when not marked Requires_Overriding.
10849 Improve warnings for in out parameters
10850 (Analyze_Function_Return): Warn for disallowed null return
10851 Warn on return from procedure with unset out parameter
10852 Ensure consistent use of # in error messages
10853 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10854 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10855 the implicit conversion of the expression done for anonymous access
10856 types. This is required to generate the code of the null excluding
10857 check (if required).
10859 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10860 A formal parameter is never publicly referenceable outside of its body.
10861 (Check_References): For an unreferenced formal parameter in an accept
10862 statement, use the same warning circuitry as for subprogram formal
10864 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10865 Output_Unreferenced_Messages, containing the part of that routine that
10866 is now reused for entry formals as described above.
10867 (Goto_Spec_Entity): New function
10868 (Check_References): Do not give IN OUT warning for dispatching operation
10869 Improve warnings for in out parameters

10876 Javier Miranda <miranda@adacore.com>
10877 Gary Dismukes <dismukes@adacore.com>
10879 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10880 (Expand_N_Attribute_Reference): Further unify the handling of the
10881 three forms of access attributes, using common code now for all three
10882 cases. Add a test for the case of applying an access attribute to
10883 an explicit dereference when the context is an access-to-interface
10884 type. In that case we need to apply the conversion to the prefix
10885 of the explicit dereference rather than the prefix of the attribute.
10886 (Attribute_Version, UET_Address): Set entity as internal to ensure
10887 proper dg output of implicit importation.
10888 (Expand_Access_To_Type): Removed.
10889 (Expand_N_Attribute_Reference): Merge the code from the three cases
10890 of access attributes, since the processing is largely identical for
10891 these cases. The substantive fix here is to process the case of a
10892 type name prefix (current instance case) before handling the case
10893 of interface prefixes.

10898 Robert Dewar <dewar@adacore.com>
10900 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10901 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10902 type that is an anonymous access to controlled object, establish
10903 an associated finalization chain to avoid corrupting the global
10904 finalization list when a dynamically allocated object designated
10905 by such a component is deallocated.
10906 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10907 functions that need it, even when not marked Requires_Overriding.
10908 (Initialize_Tag): Replace call to has_discriminants by call to
10909 Is_Variable_Size_Record in the circuitry that handles the
10910 initialization of secondary tags.
10911 (Is_Variable_Size_Record): New implementation.
10912 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10913 Suppress_Initialization pragma for a derived type.
10914 (Is_Variable_Size_Record): New subprogram.
10915 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10916 initial version of this routine and also fixes problems causing
10917 incomplete initialization of the table of interfaces.
10918 (Build_Init_Procedure): Improve the generation of code to initialize the
10919 the tag components of secondary dispatch tables.
10920 (Init_Secondary_Tags): New implementation that simplifies the previous
10921 version of this routine.
10922 (Make_DT): Add parameter to indicate when type has been frozen by an
10923 object declaration, for diagnostic purposes.
10924 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10925 diagnose attemps to freeze a subprogram when some untagged type of its
10926 profile is a private type whose full view has not been analyzed yet.
10927 (Freeze_Array_Type): Generate init proc for packed array if either
10928 Initialize or Normalize_Scalars is set.
10929 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10930 constructing the new profile, copy the null_exclusion indicator for each
10931 parameter, to ensure full conformance of the new body with the spec.
10933 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10934 Create wrappers for constructor functions that need it, even when not
10935 marked Requires_Overriding.
10936 (Covers): Handle properly designated types of anonymous access types,
10937 whose non-limited views are themselves incomplete types.
10938 (Add_Entry): Use an entity to store the abstract operation which hides
10940 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10941 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10942 initialization aggregate.
10943 (Function_Interp_May_Be_Hidden): Rename to
10944 Function_Interp_Has_Abstract_Op.
10945 (Has_Compatible_Type): Remove machinery that skips interpretations if
10946 they are labeled as potentially hidden by an abstract operator.
10947 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10948 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10949 (Write_Overloads): Output the abstract operator if present.
10950 (Add_Entry): Before inserting a new entry into the interpretation table
10951 for a node, determine whether the entry will be disabled by an abstract
10953 (Binary_Op_Interp_May_Be_Hidden): New routine.
10954 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10956 (Function_Interp_May_Be_Hidden): New routine.
10957 (Has_Compatible_Type): Do not consider interpretations hidden by
10958 abstract operators when trying to determine whether two types are
10960 (Has_Hidden_Interp): New routine.
10961 (Set_May_Be_Hidden_Interp): New routine.
10962 (Write_Overloads): Write the status of flag May_Be_Hidden.

10967 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
10968 types declared in the declarative part of a nested package body or in
10969 the proper body of a stub.
10970 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10971 of the same dispatch table slot to renamed primitives.
10972 (Make_Select_Specific_Data_Table): Handle private types.
10973 (Tagged_Kind): Handle private types.
10974 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10975 output of implicit importation and exportation.
10976 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10977 first formal of the thunk is always associated with the controlling
10978 type. In addition perform the following code cleanup: remove formal
10979 Thunk_Alias which is no longer required, cleanup evaluation of the
10980 the controlling type, and update the documentation.
10981 Replace occurrence of Default_Prim_Op_Count by
10982 Max_Predef_Prims. Addition of compile-time check to verify
10983 that the value of Max_Predef_Prims is correct.
10984 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10985 (Make_DT): Add parameter to indicate when type has been frozen by an
10986 object declaration, for diagnostic purposes.
10987 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10988 construction of statically allocated dispatch tables.
10989 (Make_DT): In case of library-level tagged types export the declaration
10990 of the primary tag. Remove generation of tags (now done by Make_Tags).
10991 Additional modifications to handle non-static generation of dispatch
10992 tables. Take care of building tables for asynchronous interface types
10993 (Make_Tags): New subprogram that generates the entities associated with
10994 the primary and secondary tags of Typ and fills the contents of Access_
10995 Disp_Table. In case of library-level tagged types imports the forward
10996 declaration of the primary tag that will be declared later by Make_DT.
10997 (Expand_Interface_Conversion): In case of access types to interfaces
10998 replace an itype declaration by an explicit type declaration to avoid
10999 problems associated with the scope of such itype in transient blocks.

11002 Ed Schonberg <schonberg@adacore.com>
11003 Javier Miranda <miranda@adacore.com>
11005 * exp_util.ads, exp_util.adb:
11006 This patch replaces a number of occurrences of explicit tests for N_Null
11007 with calls to Known_Null. This improves tracking of null values, since
11008 Known_Null also catches null constants, and variables currently known to
11009 be null, so we get better tracking.
11010 (Ensure_Defined): create an itype reference only in the scope of the
11012 (Side_Effect_Free): A selected component of an access type that
11013 denotes a component with a rep clause must be treated as not
11014 side-effect free, because if it is part of a linked structure its
11015 value may be affected by a renaming.
11016 (Expand_Subtype_From_Expr): For limited objects initialized with build
11017 in place function calls, do nothing; otherwise we prematurely introduce
11018 an N_Reference node in the expression initializing the object, which
11019 breaks the circuitry that detects and adds the additional arguments to
11020 the called function. Bug found working in the new patch for statically
11021 allocated dispatch tables.
11022 (Is_Library_Level_Tagged_Type): New subprogram.
11023 (Remove_Side_Effects): If the expression of an elementary type is an
11024 operator treat as a function call.
11025 (Make_Literal_Range): If the index type of the array is not integer, use
11026 attributes properly to compute the constraint on the resulting aggregate
11029 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11030 class-wide type whose base type is an incomplete private type, leave
11031 class-wide type unfrozen so that freeze nodes can be generated
11032 properly at a later point.
11033 (Freeze_Entity, array case): Handle case of pragma Pack and component
11034 size attributre clause for same array.

11091 attribute Body in package Naming. Do not replace a source/unit in the
11092 same project when the order of the source dirs are known. Detect
11093 duplicate sources/units in the same project when the order of the
11094 source dirs are not known.
11095 (Check_Ada_Name): Allow all identifiers that are not reserved words
11097 Major update of the Project Manager and of the project aware tools,
11098 including gprmake, so that the same sources in the GNAT repository
11099 can be used by gprbuild.

11101 directory of non extending project to nil.
11102 Change type of path name variables to be Path_Name_Type
11103 (Locate_Directory): Make sure that on Windows '/' is converted to '\',

11689 takes progenitor types into account.
11690 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11691 traversing over the primitives of the formal and actual types to locate
11692 any abstract subprograms of the actual type that correspond to a
11693 nonabstract subprogram of the formal type's ancestor type(s), and issue

11710 an access_to_constant type.
11711 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11712 type, the candidate operations are found in the scope of declaration of
11713 the type, because the type has no primitive subprograms.
11714 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11715 a private extension, only examine visible components before trying to
11716 analyze as a prefixed call.

13003 (Complete_Object_Operation): Diagnose properly an object that is not
13004 aliased when the corresponding controlling formal is an access
13006 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13007 ambiguous calls in prefixed notation, where two primitives differ only
13008 in that the controlling argument of one is an access parameter.
13010 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13011 whether a function that returns an unconstrained type can be inlined.
13012 (Process_Formals): Diagnose properly the illegal use of an incomplete
13013 type in the profile of an access_to_subprogram declaration.
13014 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13015 operations are attached to the corresponding record.
13016 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13017 When processing a primitive of a concurrent type which implements an
13018 interface change the type of all controlling formals to that of the
13019 corresponding record type.
13020 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13021 to determine the tagged type to which a primitive belongs.
13022 (Check_Conventions): Capture condition to ignore a primitive operation
13023 (which is shared between the loop in Check_Conventions and the one in
13024 Check_Convention) in a new local function Skip_Check.
13025 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13026 confusion with Check_Conventions' own Prim_Op local variable.
13027 (Create_Extra_Formals): Test for a tagged result type rather than a
13028 controlling result when determining whether to add a BIP_Alloc_Form
13029 formal and a BIP_Final_List formal to the function.
13030 (Check_Conformance); For parameters that are anonymous access types,
13031 subtype conformance requires that the not null and the constant
13032 indicators must match
13033 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13034 to retrieve the appropriate type when processing a concurrent type
13035 declared within a generic. Minor comment reformatting. Change invocation
13036 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13038 (Analyze_Subprogram_Body): If the return type of a function is an
13039 anonymous access to the limited view of a class-wide type, and the
13040 non-limited view of the type is available, update the type of the
13041 function so that code can be generated.
13042 (Process_Formals): In case of access-subtype itype whose designated
13043 type is also an itype (situation that happens now with access to
13044 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13045 attribute to avoid backend problems.
13046 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13047 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13048 anonymous types' designated types are same before testing
13049 Subtypes_Statically_Match.
13050 (Create_Extra_Formals): Test for a named access parameter that is a
13051 controlling formal as an additional condition for adding an
13052 accessibility level formal. This can occur in the subp type created for
13053 dispatching calls in Expand_Dispatching_Call, and allows calling
13054 Create_Extra_Formals from that procedure rather than special-casing the
13055 extra formals there.
13056 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13057 when the function has a controlling result.
13058 (Check_Returns): Add much more knowledge of the optimization of local
13059 raise statements to gotos, to retain proper warnings in this case.
13060 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13061 nodes when looking for last statement.
13063 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13064 class-wide types visible through limited with clauses.
13065 (Add_One_Interp): If the operands are anonymous access types, the
13066 predefined operator on universal_access is immediately visibles
13067 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13068 other anonymous access types.
13069 (Disambiguate): Take into account CIL convention.
13070 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13072 2007-06-06 Robert Dewar <dewar@adacore.com>
13074 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13075 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13076 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13077 Fix lower bound of tables.
13080 * nlists.adb: Ditto.
13081 (Prev_Node, Next_Node): Change index type to Int so that it properly
13082 covers the range First_Node_Id - 1 up.
13084 2007-06-06 Javier Miranda <miranda@adacore.com>
13085 Ed Schonberg <schonberg@adacore.com>
13086 Bob Duff <duff@adacore.com>
13087 Hristian Kirtchev <kirtchev@adacore.com>
13089 * exp_aggr.ads, exp_aggr.adb:
13090 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13091 in extension aggregates.
13092 (Flatten): Other conditions being met, an aggregate is static if the
13093 low bound given by component associations is different from the low
13094 bound of the base index type.
13095 (Packed_Array_Aggregate_Handled): If the component type is itself a
13096 packed array or record, the front-end must expand into assignments.
13097 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13098 Init_Pr, instead of Ancestor_Is_Expression.
13099 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13100 coextension chain root, either generate a list controller or use the
13101 already existing one.
13102 (Static_Array_Aggregate): New procedure to construct a positional
13103 aggregate that can be handled by the backend, when all bounds and
13104 components are compile-time known constants.
13105 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13106 types covering interface types into assignments.
13107 (Replace_Type): move to Build_Record_Aggr_Code.
13108 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13109 interface type, convert to the definite type of the aggregate itself,
13110 so that needed components are visible.
13111 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13112 components and the context is an extended return statement do not
13113 create a transient block for it, to prevent premature finalization
13114 before the return is executed.
13115 (Gen_Assign): Do not generate a call to deep adjust routine if the
13116 component type is itself an array of controlled (sub)-components
13117 initialized with an inner aggregate.
13118 (Component_Check): New name for Static_Check. This name is now more
13119 appropriate, and documentation is added which was missing.
13120 (Component_Check): Add test for bit aligned component value
13121 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13122 Tagged_Comps, name is more appropriate given added function below.
13123 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
13125 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13126 Javier Miranda <miranda@adacore.com>
13127 Robert Dewar <dewar@adacore.com>
13129 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13130 Terminated: Add unchecked type conversion from System.Address to
13131 System.Tasking.Task_Id when calling the predefined primitive
13133 Disable new Ada 05 accessibility check for JVM.NET targets, which
13134 cannot be implemented in a practical way.
13135 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13136 the sources always references the tag of the actual object. Therefore,
13137 if 'Tag is applied in the sources to class-wide interface objects we
13138 generate code that displaces "this" to reference the base of the object.
13139 (Expand_N_Attribute_Reference, case Size): Return specified size if
13140 known to front end.
13141 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13142 has code that displaces the pointer of the object to manage interface
13143 types. However this code must not be executed when the prefix is a
13144 subprogram. This bug caused the wrong expansion of the internally
13145 generated assignment that fills the dispatch table when the primitive
13146 is a function returning a class-wide interface type.
13147 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13148 Set_Attribute_Name for Name_Unaligned_Valid.
13150 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13151 Gary Dismukes <dismukes@adacore.com>
13153 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13154 If the initialization is the equivalent aggregate of the initialization
13155 procedure of the type, do not remove it.
13156 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13157 initialized to null from having their expression reset to empty and
13158 note this exception in the comment.

13161 Robert Dewar <dewar@adacore.com>
13162 Ed Schonberg <schonberg@adacore.com>
13163 Gary Dismukes <dismukes@adacore.com>
13165 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13166 Add "with" and "use" clauses for Sem_Attr.
13167 (Expand_Current_Value): Do not replace occurences of attribute
13168 references where the prefix must be a simple name.
13170 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13171 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13172 Attribute_Requires_Simple_Name_Prefix.
13173 (Name_Modifies_Prefix): Body of new function.
13174 (Requires_Simple_Name_Prefix): Body of new function.
13175 (Resolve_Attribute, case Access): Improve error message for case of
13176 mismatched conventions.
13177 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13179 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13180 constrained subtype for a nominal unconstrained type, use its base type
13181 to check for conformance with the context.
13182 (Resolve_Attribute): Remove test of the access type being associated
13183 with a return statement from condition for performing accessibility
13184 checks on access attributes, since this case is now captured by
13185 Is_Local_Anonymous_Access.
13186 (Analyze_Access_Attribute): Set Address_Taken on entity
13187 (Analyze_Attribute, case Address): Set Address_Taken on entity
13188 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13189 validating an access attribute whose prefix is a current instance.
13190 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13191 applied to dispatching operations, if freezing is required then we set
13192 the attribute Has_Delayed_Freeze in the prefix's entity.
13193 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13194 current scope if access of local subprogram taken
13195 (Analyze_Access_Attribute): Check legality of self-reference even if the
13196 expression comes from source, as when a single component association in
13197 an aggregate has a box association.
13198 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13199 the prefix if it is a protected operation and the attribute is
13200 Unrestricted_Access.
13201 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13202 reference to the base type of the context, to force a constraint check
13203 when the context is an access subtype with an explicit constraint.
13204 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13205 node is rewritten as an interface conversion. leave unanalyzed after
13206 resolution, to ensure that type checking against the context will take

13210 Javier Miranda <miranda@adacore.com>
13211 Robert Dewar <dewar@adacore.com>
13213 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13214 wrapper when the full view of the controlling type of an inherited
13215 function that dispatches on result implements interfaces.
13216 (Expand_N_Object_Declaration): In cases where the type of the
13217 declaration is anonymous access, create finalization list for it.
13218 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13219 if the object has no explicit initialization, to match description of
13220 functionality of pragam Persistent_BSS.
13221 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13222 new function to build static aggregates, to replace initialization call
13223 when static initialization is desired.
13224 (Freeze_Type): Generate a list controller for an access type whenever
13225 its designated type has controlled anonymous access discriminants.
13226 (Build_Equivalent_Aggregate): New procedure to compute a static
13227 aggregate to be used as default initialization for composite types,
13228 instead of a generating a call to the initialization procedure for the
13230 (Build_Initialization_Call): When available, replace a call to the
13231 initialization procedure with a copy of the equivalent static aggregate
13233 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13234 declarations for objects of a class-wide interface type, rather than
13235 just identifiers, to prevent visibility problems.
13236 (Expand_N_Object_Declaration): When expanding the declaration for an
13237 object of a class-wide interface type, preserve the homonym chain of
13238 the original entity before exchanging it with that of the generated
13239 renaming declaration.
13240 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13241 active, because there is no way to handle the exception.
13242 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13243 to do a minimum decoration of the Access_Disp_Table list.
13244 (Expand_Record_Controller): Avoid the addition of the controller between
13245 the component containing the tag of a secondary dispatch table and its
13246 adjacent component that stores the offset to the base of the object.
13247 This latter component is only generated when the parent type has
13248 discriminants ---documented in Add_Interface_Tag_Components).
13249 (Apply_Array_Size_Check): Removed, no longer needed.
13250 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13251 components, create a Master_Entity for it only if it contains tasks.
13252 (Build_Init_Procedure): Suppress the tag assignment compiling under
13254 (Freeze_Record_Type): Remove code associated with creation of dispatch
13256 (Init_Secondary_Tags): Update type of actuals when generating calls to
13257 Ada.Tags.Set_Offset_To_Top
13258 (Stream_Operation_OK): Disable use of streams compiling under no
13260 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13261 if Has_Init_Expression set.
13262 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13263 Register_Primitive, which provides the same functionality.
13264 (Requires_Init_Proc): Return false in case of interface types.
13265 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13267 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13268 is always associated with a predefined primitive because the internal
13269 entities associated with interface types are not predefined primitives.
13270 Therefore, the call to Is_Internal is replaced by a call to the
13271 function Is_Predefined_Dispatching_Operation.
13272 (Make_Eq_If): When generating the list of comparisons for the
13273 components of a given variant, omit the controller component that is
13274 present if the variant has controlled components.
13276 2007-06-06 Javier Miranda <miranda@adacore.com>
13277 Hristian Kirtchev <kirtchev@adacore.com>
13278 Bob Duff <duff@adacore.com>
13280 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13281 handle the creation of finalization lists and calls for nested
13282 coextensions when the root of the chains is part of a return statement.
13283 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13285 (Expand_Record_Equality): Skip components that are interface types.
13286 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13287 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13288 with Rewrite_Coextension. Change the condition for detecting coextension
13290 (Is_Local_Access_Discriminant): Removed.
13291 (Rewrite_Coextension): New routine which rewrites a static coextension
13292 as a temporary and uses its unrestricted access in the construction of
13294 (Complete_Coextension_Finalization): New routine. Generate finalization
13295 attachment calls to all delayed coextensions.
13296 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13297 the allocator is not a coextension itself and has delayed coextensions.
13298 If the current allocator is controlled, but also a coextension, delay
13299 the generation of the finalization attachment call.
13300 Rename local variable "Node" to "Nod" in order to avoid confusion with
13302 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13303 limited types that are not inherently limited. Such an allocator is
13304 illegal, but is generated by the expander for a return statement, to
13305 copy the result onto the secondary stack. This is the only case where a
13306 limited object can be copied. Generate code to displace the pointer
13307 to the object if the qualified expression is a class-wide interface
13308 object. Such displacement was missing and hence the copy of the object
13310 (Apply_Accessibility_Check): Handle allocated objects initialized in
13312 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13313 and Expand_Allocator_Expression. Allocating class-wide interface objects
13314 this routine displaces the pointer to the allocated object to reference
13315 the component referencing the corresponding secondary dispatch table.
13316 Expand_Allocator_Expression): Add missing support to allocate class-wide
13317 interface objects initialized with a qualified expression.
13318 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13319 function result type, and use the finalization list associated with the
13320 function scope in that case (such an anonymous type should not be
13321 treated like an access parameter's type).
13323 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13324 Gary Dismukes <dismukes@adacore.com>
13325 Javier Miranda <miranda@adacore.com>
13327 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13328 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13329 required exception handler.
13330 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13331 properly the case of a function whose return type is a limited
13332 class-wide interface type. Modify the code of the accessibility
13333 check to handle class-wide interface objects. In this case we need to
13334 displace "this" to reference the primary dispatch table to get access
13335 to the TSD of the object (to evaluate its accessibility level).
13336 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13337 rather than a controlling result as one of the conditions for
13338 generating tests of the implicit BIP_Alloc_Form formal. The
13339 initialization assignment is also handled according to whether the
13340 result is tagged instead of controlling.
13341 In the case where the init assignment is inserted in the "then" part of
13342 the allocation conditional, rewrite the target to be a dereference of
13343 the implicit BIP_Object_Access formal.
13344 If the returned value is unconstrained and created on the secondary
13345 stack, mark the enclosing block and function so that the secondary
13346 stack is not reclaimed on return.
13347 Treat returns from functions with controlling results similarly to
13348 returns from functions with unconstrained result subtypes.
13349 If the object returned is unconstrained, and an allocator must be
13350 created for it, analyze the allocator once the block for the extended
13351 return is installed, to ensure that finalizable components
13352 of the expression use the proper finalization list. Guard the call to
13353 Move_Final_List with a check that there is something to finalize.
13354 (Make_Tag_Ctrl_Assignment): Use "old" handling
13355 of controlled type assignment for virtual machines, since new code uses
13356 unsupported features (such as direct access to bytes in memory).
13358 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13359 Ed Schonberg <schonberg@adacore.com>
13361 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13362 accessibility actual, check for the case of an aliased object that has
13363 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13364 we fall into processing for the attribute rather than the name of the
13366 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13367 formal has its address taken in the body, create a temporary to capture
13368 value. If the return type is a limited interface, do not treat the
13369 return value as Controlled.
13370 (Is_In_Place_Function): If the return type is a limited interface,
13371 treat as returning in place. The actual returned object may not always
13372 be limited, but the caller has to assume that it is returned in place.
13373 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13374 context of an allocator, use the correct finalization chain (that is,
13375 the chain belonging to the access type, rather than the chain belonging
13376 to the current scope).
13377 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13378 result type rather than a controlling result as a precondition for
13379 adding an allocation form actual to a build-in-place call.
13380 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13381 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13382 primitive in the dispatch tables. This work is now done by Make_DT when
13383 the type is frozen.
13384 (Register_Predefined_DT_Entry): Removed.
13385 (Add_Return): If end label is not present, use sloc of last statement
13386 for generated return statement in procedure, for better gdb behavior
13388 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13389 object address nodes to ensure proper processing by routines like
13391 (Expand_Call): Fix generation of validity check for parameter
13392 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13393 the allocation form parameter if the result subtype is constrained,
13394 except when the function has a controlling result.
13395 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13396 rather than Is_Controlled and Has_Controlled_Component, since we want to
13397 include class-wide result types in this treatment. Also test for a
13398 controlling result, since that also requires passing a finalization
13400 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13401 even when the result subtype is constrained, to handle calls involving
13402 controlling results.
13403 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13404 is now called even when the result subtype is constrained, to handle
13405 calls involving controlling results.
13406 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13407 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13408 now performs the test).
13409 (Make_Build_In_Place_Call_In_Object_Declaration):
13410 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13411 constrained, to handle calls involving controlling results.
13412 (Add_Return): Accomodate rewritten pattern from local raise to goto
13413 transformation, so that we still recognize an transfer statement
13414 and do the right thing here in that case.
13415 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13416 and end of subprogram code.
13417 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13418 support for primitives that are functions (without formals) with a
13419 controlling result.
13420 (Inherited_From_Formal): If the actual subtype has not generic parent
13421 type, it is not an actual for a formal derived type, and there is no
13422 operation to inherit from the formal.

13436 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13437 appears in the optional statement list of a triggering alternative, the
13438 scope actions can be inserted directly there, and not in the list that

13470 functionality when the backend is generating code.
13471 Otherwise any serious error
13472 reported by the backend calling the frontend routine Error_Msg

13514 deallocation of class-wide interface objects.
13515 (Expand_Dispatching_Constructor_Call): Take into account that if the

13517 function returns a class-wide interface type; otherwise the returned
13518 object would be actual. The frontend previously accepted returning
13519 interface types because Expand_Interface_Actuals silently performed
13520 the management of the returned type "as if" it were a class-wide
13522 (Expand_Dispatching_Constructor_Call): Replace call to
13523 Make_DT_Access_Action by direct call to Make_Function_Call.

13615 subtype from the function call, as is done for private types.
13616 (Side_Effect_Free): An expression that is the renaming of an object or
13617 whose prefix is the renaming of a object, is not side-effect free
13618 because it may be assigned through the renaming and its value must be

13732 defined in GNAT.IO, which might not be stdout
13733 (Is_Valid): Adjust comment to mention that a positive reply means that
13734 Header_Of may be used to retrieve the allocation header associated with

14374 of calling Set_All_DT_Position to re-evaluate the position of the
14375 entries in the dispatch table. Such reevaluation is not desired if

15243 restriction No_Dispatching_Calls.
15244 (Resolve_Call): If the call returns an array, the context imposes the
15245 component type of the array, and the function has one non-defaulted
15246 parameter, rewrite the call as the indexing of a call with a single
15247 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15249 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15250 the master of the created object is the innermost enclosing statement.
15251 (Remove_Conversions): For a binary operator, check if type of second
15252 formal is numeric, to check if an abstract interpretation is present
15253 in the case of exponentiation as well.

15348 (E_Return_Statement): This node type has the Finalization_Chain_Entity
15349 attribute, in case the result type has controlled parts.
15350 (Requires_Overriding): Add this new flag, because "requires
15351 overriding" is subtly different from "is abstract" (see AI-228).
15352 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
15353 Is_Abstract_Type. Make sure these are called only when appropriate.
15354 (Has_Pragma_Unreferenced_Objects): New flag
15356 * exp_ch5.adb (Expand_N_Assignment_Statement): If the left-hand side is

15386 Add_Task_Actuals_To_Build_In_Place_Call with the appropriate master.
15387 (Expand_Inlined_Call): If the subprogram is a null procedure, or a
15388 stubbed procedure with a null body, replace the call with a null
15389 statement without using the full inlining machinery, for efficiency
15390 and to avoid invalid values in source file table entries.

15415 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
15416 "abstract subprograms must be visible" message, whether or not the type
15417 is an interface; that is, remove the special case for interface types.

15443 build-in-place functions with result type with controlled parts.
15444 Remove no longer used entities.
15446 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
15447 longer needed, because the full type is now limited, and therefore a

15449 (Foreign_Task_Level): New constant.
15451 * s-tassta.ads, s-tassta.adb (Move_Activation_Chain): New procedure to

15480 to handle properly the anonymous access case.
15482 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
15483 for all access attributes, because overload resolution should work the
15484 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This

15486 "X'Unrestricted_Access = Y'Access" and so forth to match.

15494 attempt to derive from a synchronized tagged type.
15495 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
15496 type, inherit the class-wide type already created, because it may
15497 already have been used in a self-referential anonymous access component.
15498 (Mentions_T): Recognize self-referential anonymous access components
15499 that use (a subtype of) the class-wide type of the enclosing type.
15500 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15501 Derived_Type for Prev formal on call to
15502 Check_Anonymous_Access_Components rather than Empty.
15503 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15504 a record extension in deciding whether to create a class-wide type,

15507 to stand-alone object declarations as well as component declarations.

15512 the associated_node for the itype is the type declaration itself.

15550 (Compile_Sources): Do nothing, not even check if the source is up to
15551 date, if its project is externally built.
15552 (Compile): When compiling a predefined source, add -gnatpg
15553 as the second switch, after -c.
15554 (Compile_Sources): Allow compilation of Annex J renames without -a

15558 gnatbind if the ALI file effectively exists.
15559 (Initialize): Add the directory where gnatmake is invoked in front of
15560 the path if it is invoked from a bin directory, even without directory

15585 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15586 when -gnatg is not specified.
15587 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15588 there is no need to generate always a record_definition_node in case
15589 of synchronized interface types.

15616 (Convert_Aggr_In_Allocator): If the allocator is for an access
15617 discriminant and the type is controlled. do not place on a finalization
15618 list at this point. The proper list will be determined from the

15637 succeed in that case, even when the expression originates from a
15638 parameter of the containing subprogram.
15639 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15640 under No_Dispatching_Calls restriction. During the semantic analysis
15641 we already notified such violation.

15659 initialize most the TSD components by means of an aggregate.
15660 Modify the declaration of the object containing the TSD
15661 because we now expand code that has a higher level of abstraction.
15662 The TSD has a discriminant containing the Inheritance Depth Level,
15663 value that is used in the membership test but also to fix the size
15664 of the table of ancestors.
15665 (Expand_Interface_Conversion): Insert function body at the closest place
15666 to the conversion expression, to prevent access-before-elaboration
15667 errors in the backend.

15693 (Expand_Dispatching_Call): Replace generation of call to the run-time
15694 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15695 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15697 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15698 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

15708 returns an actual parameter expression for both named and positional
15711 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15712 check violation of restriction No_Dispatching_Calls.
15713 (Check_Controlling_Type): A formal of a tagged incomplete type is a

15720 specify Any_Limited_Interface, and this functionality is already
15721 provided by the function Has_Abstract_Interfaces.
15722 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15723 support concurrent types implementing interfaces.
15724 (Find_Implemented_Interface): Removed. All the calls to this subprogram

15742 Cyrille Comar <comar@adacore.com>
15744 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
15745 anonymous, use finalization list of enclosing dynamic scope.
15746 (Expand_N_Package_Declaration): For a library package declaration
15747 without a corresponding body, generate RACW subprogram bodies in the
15748 spec (just as we do for the task activation call).
15749 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15750 Is_Abstract_Type. Make sure these are called only when appropriate.
15751 Remove all code for DSP option
15752 (CW_Or_Controlled_Type): new subprogram.
15754 2007-04-06 Eric Botcazou <botcazou@adacore.com>

15756 Gary Dismukes <dismukes@adacore.com>
15758 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15759 parameter. If it is set to true, return a result capped according to
15760 the global upper bound for the index of an entry family.

15766 is potentially large.
15767 (Build_Entry_Count_Expression): If the family is potentially large, call
15768 Family_Size with 'Cap' set to true.
15769 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15770 a protected version of an operation declared in the private part of
15771 a protected object, because they may be invoked through a callback.
15772 (Set_Privals): If the type of a private component is an anonymous access
15773 type, do not create a new itype for each protected body.
15774 If the body of a protected operation creates
15775 controlled types (including allocators for class-widetypes), the
15776 body of the corresponding protected subprogram must include a
15778 (Build_Activation_Chain_Entity): Build the chain entity for extended
15780 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15781 to determine whether operation overrides an inherited primitive.

15783 for a possible overriding candidate.
15784 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15785 hold an actual parameter value since its initialization is separated

15789 2007-04-06 Thomas Quinot <quinot@adacore.com>
15790 Pablo Oliveira <oliveira@adacore.com>
15792 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15793 Do an Unchecked_Conversion to handle the passage from the Underlying
15794 Type to the Base Type when calling Build_To_Any_Call and
15795 Build_From_Any_Call.
15796 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15797 E_Constant, depending upon Variable formal.
15798 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15799 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15800 parameter that requires an extra constrained parameter, declare
15801 temporary for actual as a variable, not a constant.
15802 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15803 the unit being compiled is the one that contains the stub type.
15804 Change primitive operation name for the RACW associated with a RAS
15805 from Call to _Call so it cannot clash with any legal identifier.
15806 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15808 (Append_RACW_Bodies): New subprogram.
15809 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15810 Add_Receiving_Stubs_To_Declarations functions.
15811 When expanding a package body, this list correspond to the
15812 statements in the HSS at the end of the pacakge.
15813 When expanding a package spec, this list correspond to the
15815 (Add_Receiving_Stubs_To_Declarations): Append the function
15816 registering the receiving stubs at the end of the 'Stmts' list.
15817 (RCI_Package_Locator): Pass the new Version generic formal when
15818 instantiating a RCI_Locator package.
15819 (Build_From_Any_Function): To compute the High bound for an
15820 unconstrained array actual, we add the Low bound with the length.
15821 Thus we must convert the low bound and the length to an appropriate
15822 type before doing the sum.
15823 (Build_Subprogram_Receiving_Stubs, PolyORB):
15824 * Retrieve the extra formals parameters at the
15825 end of the parameter stream.
15826 * Use Move_Any_Value to write back out parameters
15827 after executing the request as it is more efficient
15828 than Copy_Any_Value.
15829 * Build the any containing Extra Formals with the
15830 appropriate typecode.
15831 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15832 empty Component_List.
15833 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15834 the tree the declaration for an object that serves as actual parameter
15835 in server-side stubs.
15836 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15837 PolyORB_Support.Build_Subprogram_Receiving_Stubs):

15845 function with the first not implicit parent type.
15846 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15847 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15848 typecode from the Etype. Therefore we retrieve the correct typecode
15849 with a call to Get_Any_Type.
15850 (Copy_Specification): Do controlling formal type substitution based on
15851 Is_Controlling_Formal flag, instead of caller-provided object type.
15852 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15853 a RACW primitive operation, we might get a subprogram declaration for an
15854 ancestor of the RACW designated type (not for the designated type
15855 itself), in the case where this operation is inherited. In this case we
15856 have no easy means of determining the original tagged type for which
15857 the primitive was declared, so instead we now rely on
15858 Copy_Specification to use the Is_Controlling_Formal flag to determine
15859 which formals require type substitution.

15865 GNAT.Current_Exception are not allowed if pragma Restrictions
15866 (No_Exception_Propagation) is set and in any case make the associated
15867 handler unsuitable as a target for a local raise statement.
15868 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15869 run-time subprogram CW_Membership by call to Build_CW_Membership.
15870 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15871 by a function call, a temporary must be created before expanding the
15872 Constructor_Call itself, to prevent out-of-order elaboration in the
15873 back-end when stack checking is enabled..
15875 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15877 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15878 result are the bounds of the left operand, not the right.
15880 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15883 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

16002 standard 8bits encoding.
16003 (WS2SU): As above but converting from wide-sring to string.
16004 This is needed as it is necessary to have access to both versions in the
16005 runtime for the form parameter encoding support.
16006 This set of patch add support for the encoding form parameter.
16007 (S2WS): Improve implementation to handle cases where the filename is not
16008 UTF-8 encoded. In this case we default to using the current code page
16009 for the conversion.

16130 2007-04-06 Robert Dewar <dewar@adacore.com>
16132 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16133 it no longer destroys the contents of Name_Buffer or Name_Len and
16134 non-standard and invalid names are handled better.
16135 (Get_Decoded_Name_String): Improve performance by using
16136 Name_Has_No_Encodings flag in the name table.
16137 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
16138 Used for debugging printouts.

16141 Javier Miranda <miranda@adacore.com>
16142 Bob Duff <duff@adacore.com>
16144 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16145 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16146 there is no need to generate always a record_definition_node in case
16147 of synchronized interface types.
16148 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16149 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16150 illegal in Ada 95, in cases where it is legal. Change the warnings to
16151 errors in other cases. Don't give the error unless the "not null"
16152 parses properly. Correct the source position at which the error occurs.
16153 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16154 P_Null_Exclusion, to suppress "not null" warnings.

16206 Entry for pragma Unreferenced_Objects
16208 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD

16230 the default project path, initially done during elaboration of the
16232 If the prefix returned by Sdefault is null, get the prefix from a call
16233 to Executable_Prefix_Path.
16234 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16237 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16238 canonical directory name to open the directory from which files are
16240 (Record_Other_Sources): Idem.
16241 (Locate_Directory): Add the possibility to create automatically missing
16242 directories when Setup_Projects is True.
16243 Call Locate_Directory so that the directory will be created when

16245 library source copy dir and exec dir.
16247 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16250 2007-04-06 Robert Dewar <dewar@adacore.com>

16285 full word is no longer compared twice.
16287 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16289 * sem_ch10.adb (Install_Limited_Context_Clauses.
16290 Expand_Limited_With_Clause): Use a new copy of selector name in the
16291 call to Make_With_Clause. This fixes the tree structure for ASIS
16292 purposes. Nothing is changed in the compiler behaviour.
16293 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16294 a package renaming.
16295 (Install_Limited_With_Clauses): Do not install non-limited view when it
16296 is still incomplete.
16298 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16299 Gary Dismukes <dismukes@adacore.com>
16301 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16302 when capturing size information, instead of base type, which for a
16303 formal array type will be the unconstrained type.
16304 (Analyze_Formal_Object_Declaration): Add check for illegal default
16305 expressions for a formal in object of a limited type.
16306 (Instantiate_Object): Ditto.
16307 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16308 because they were defaulted in the formal package and no check applies
16310 (Check_Formal_Package_Instance): Extend conformance check to other
16311 discrete types beyond Integer.
16312 (Process_Default): Copy directly the unmatched formal. A generic copy
16313 has already been performed in Analyze_Formal_Package.
16314 (Analyze_Associations): If a formal subprogram has no match, check for
16315 partial parametrization before looking for a default, to prevent
16317 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16318 not set the instantiation environment before analyzing the actuals.
16319 Fixes regression on 8515-003 with implementation of AI-133.
16320 Set_Instance_Env checks whether the generic unit is a predefined
16321 unit, in which case the instance must be analyzed with the latest Ada
16322 mode. This setting must take place after analysis of the actuals,
16323 because the actuals must be analyzed and frozen in the Ada mode extant
16324 outside of the current instantiation.
16325 (Save_Env, Restore_Env): Preserve and restore the configuration
16326 parameters so that predefined units can be compiled in the proper Ada
16328 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16329 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16330 and Is_Abstract_Type.
16331 (Analyze_Formal_Package): For better error recovery, Add exception
16332 handler to catch Instantion_Error, which can be raised in
16333 Analyze_Associations

16336 Bob Duff <duff@adacore.com>
16337 Gary Dismukes <dismukes@adacore.com>
16339 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16340 prefix type is a discriminated subtype of the type of the formal.
16341 (Analyze_Allocator): Collect all coextensions regardless of the context.
16342 Whether they can be allocated statically is determined in exp_ch4.
16343 (Analyze_Selected_Component): If the prefix is a limited view and the
16344 non-limited view is available, use the non-limited one.
16345 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16346 therefore illegal), suggest a qualified expression rather than a type
16347 conversion, because a type conversion would be illegal in this context.
16348 (Anayze_Allocator): Trace recursively all nested allocators so that all
16349 coextensions are on the corresponding list for the root. Do no mark
16350 coextensions if the root allocator is within a declaration for a stack-
16351 allocated object, because the access discriminants will be allocated on
16353 (Analyze_Call): Remove restriction on calls to limited functions for the
16354 cases of generic actuals for formal objects, defaults for formal objects
16355 and defaults for record components.
16356 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16357 element list. Their expansion is delayed until the enclosing allocator
16358 is processed and its finalization list constructed.
16359 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16360 for an operation with the given name among the primitive operations of
16361 the corresponding record type.
16362 (Analyze_Selected_Component): If the prefix is a task type that
16363 implements an interface, and there is no entry with the given name,
16364 check whether there is another primitive operation (e.g. a function)
16366 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16367 properly the indexing of a function call written in prefix form, where
16368 the function returns an array type, and all parameters of the function
16369 except the first have defaults.
16370 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16371 the original operands, rather than relocating them, for efficiency and
16372 to work properly when an operand is overloaded.
16373 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16374 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16375 (Analyze_Selected_Component): If the prefix is a private extension, only
16376 scan the visible components, not those of the full view.
16377 (Try_Primitive_Operation): If the operation is a procedure, collect all
16378 possible interpretations, as for a function, because in the presence of
16379 classwide parameters several primitive operations of the type can match
16380 the given arguments.
16382 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16383 Robert Dewar <dewar@adacore.com>
16385 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16386 tag-indeterminate call to an abstract function, when the left-hand side

16390 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16391 Thomas Quinot <quinot@adacore.com>
16393 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16394 out of Analyze_Package_Declaration, because processing must be applied
16395 to package bodies as well, for deferred constants completed by pragmas.
16396 (Analyze_Package_Declaration): When the package declaration being
16397 analyzed does not require an explicit body, call Check_Completion.
16398 (May_Need_Implicit_Body): An implicit body is required when a package
16399 spec contains the declaration of a remote access-to-classwide type.
16400 (Analyze_Package_Body): If the package contains RACWs, append the
16401 pending subprogram bodies generated by exp_dist at the end of the body.
16402 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16403 Is_Abstract_Subprogram and Is_Abstract_Type.
16404 (Preserve_Full_Attributes): The full entity list is not an attribute
16405 that must be preserved from full to partial view.
16407 * sem_dist.adb (Add_RAS_Dereference_TSS):
16408 Change primitive name to _Call so it cannot clash with any legal
16409 identifier, and be special-cased in Check_Completion.
16410 Mark the full view of the designated type for the RACW associated with
16411 a RAS as Comes_From_Source to get proper view switching when installing
16412 private declarations.
16413 Provite a placeholder nested package body along with the nested spec
16414 to have a place for Append_RACW_Bodies to generate the calling stubs
16415 and stream attributes.
16417 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16418 Robert Dewar <dewar@adacore.com>
16420 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16421 that is a limited view, check the non-limited view if available.
16422 (Undefined): Refine error message for missing with of Text_IO
16423 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16424 to distinguish real missing with cases.
16425 Fix format of all missing with messages
16426 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16427 renaming as body when renamed entity is abstract.
16429 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16430 Javier Miranda <miranda@adacore.com>
16432 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make

16442 Javier Miranda <miranda@adacore.com>
16444 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16445 dereference of a local object R created as a reference to another
16446 object O, use the access level of O.
16447 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16448 rather than local Same_Formal_Type, to check whether protected operation
16449 overrides an inherited one.
16450 (Same_Formal_Type): New predicate, used when matching signatures of
16451 overriding synchronized operations, to handle the case when a formal
16452 has a type that is a generic actual.
16453 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16454 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16455 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16456 syntactic ambiguities involving indexing of function calls that return
16458 (Abstract_Interface_List): New subprogram that returns the list of
16459 abstract interfaces associated with a concurrent type or a
16460 concurrent record type.
16461 (Interface_Present_In_Parent): New subprogram used to check if a
16462 given type or some of its parents implement a given interface.
16463 (Collect_Abstract_Interfaces): Add support for concurrent types
16464 with interface types.
16465 (Has_Abstract_Interfaces): Add support for concurrent types with
16467 (Is_Parent): New subprogram that determines whether E1 is a parent
16468 of E2. For a concurrent type its parent is the first element of its
16469 list of interface types; for other types this function provides the
16470 same result than Is_Ancestor.
16471 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16472 (Collect_Synchronized_Interfaces): Removed because the subprogram
16473 Collect_Abstract_Interfaces provides this functionality.
16474 (Collect_Abstract_Interfaces): Minor update to give support to
16475 concurrent types and thus avoid undesired code duplication.
16476 (Get_Subprogram_Entity): Handle entry calls.
16477 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16479 (Enter_Name): Do not give -gnatwh hiding warning for record component

16495 can be an E_Return_Statement.
16496 (Is_Coextension): New flag for allocators.

16505 before propagating exception.
16507 2007-04-06 Olivier Hainque <hainque@adacore.com>
16509 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
16510 an address always within the call instruction from a return address.
16512 2007-04-06 Olivier Hainque <hainque@adacore.com>
16513 Eric Botcazou <botcazou@adacore.com>
16515 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16516 expression with a COMPOUND_EXPR including the call instead of emitting
16517 the call directly here.
16518 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16519 high bound is constant and the slice is empty. Tidy.
16520 (tree_transform, case N_Op_Not): Handle properly the case where the
16521 operation applies to a private type whose full view is a modular type.
16522 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16523 Address_Clause, use the associated Expression as the GNAT tree
16524 representing the choice value to ensure the corresponding GCC tree is
16525 of the proper kind.
16526 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16527 instead of just the operands, as the base GCC stabilize_reference does.
16528 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16529 requested; otherwise fail.
16530 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
16532 2007-04-06 Thomas Quinot <quinot@adacore.com>

16535 implementation of UI_Div.
16536 (UI_Div): Reimplement as a call to UI_Div_Rem.
16537 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16538 remainder, avoiding the cost of a multiplication and a subtraction.
16539 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
16540 provides both quotient and remainder in a single computation.
16541 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
16542 functions for uint.
16543 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
16544 is undefined if the given n is not inversible.
16546 2007-04-06 Olivier Hainque <hainque@adacore.com>
16548 * utils2.c (known_alignment): Handle COMPOUND_EXPR, COND_EXPR and
16549 BIT_AND_EXPR. Handle also VIEW_CONVERT_EXPR, as the other conversion

16553 Olivier Hainque <hainque@adacore.com>
16555 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
16556 when updating the contents of the old pointer to an unconstrained array.
16557 (end_subprog_body): Set error_gnat_node to Empty.
16558 (write_record_type_debug_info): Do not be unduly sparing with our bytes.

16810 anonymous access types.
16811 (Valid_Conversion): For a conversion to a numeric type occurring in an
16812 instance or inlined body, no need to check that the operand type is

17484 Make use of concatenation now allowed in compiler
17485 (Executable_Prefix.Get_Install_Dir): First get the full path, so that

17518 the parent part is a build-in-place function call, generate assignments.
17519 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17520 are build-in-place function calls.
17521 (Replace_Self_Reference): New subsidiary of
17522 Make_OK_Assignment_Statement, to replace an access attribute that is a
17523 self-reference into an access to the appropriate component of the
17524 target object. Generalizes previous mechanism to handle self-references
17525 nested at any level.
17526 (Is_Self_Referential_Init): Remove, not needed.
17527 (Is_Self_Referential_Init): New predicate to simplify handling of self
17528 referential components in record aggregates.
17529 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
17530 check for presence of entity before checking for self-reference.
17531 (Has_Default_Init_Comps): Return True if a component association is a
17532 self-reference to the enclosing type, which can only come from a
17533 default initialization.
17534 (Make_OK_Assignment_Statement): If the expression is of the form
17535 Typ'Acc, where Acc is an access attribute, the expression comes from a
17536 default initialized self-referential component.
17537 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17538 that has been derived from several abstract interfaces we must also
17539 initialize the tags of the secondary dispatch tables.

17544 Robert Dewar <dewar@adacore.com>
17547 (Expand_Access_To_Protected_Op): If the context indicates that an access
17548 to a local operation may be transfered outside of the object, create an
17549 access to the wrapper operation that must be used in an external call.
17550 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17551 target, pass the Valid attribute applied to a floating-point prefix on
17552 to the back end without expansion.
17553 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17554 the allocated storage when it is specified by a per-object expression.
17555 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17556 Nothing to do here, the attribute has been rewritten during semantic
17558 (Expand_Attribute_Reference): Handle expansion of the new Priority
17560 (Find_Fat_Info): Handle case of universal real
17561 (Expand_Access_To_Protected_Op): Fix use of access to protected
17562 subprogram from inside the body of a protected entry.
17563 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
17564 'Access and 'Unrestricted_Access, to transform the attribute reference
17565 into a fat pointer.
17566 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17567 subcomponent's enclosing variable is aliased with a constrained subtype.
17568 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17569 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17570 an aliased prefix must be known to be constrained in order to use True
17571 for the attribute value, and now it's possible for some aliased views
17572 to be unconstrained.
17574 2006-10-31 Robert Dewar <dewar@adacore.com>
17576 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17577 (Expand_Entity_Reference): Correct error of not handling subprogram
17578 formals in current_value processing.
17580 2006-10-31 Javier Miranda <miranda@adacore.com>

17582 Ed Schonberg <schonberg@adacore.com>
17583 Gary Dismukes <dismukes@adacore.com>
17585 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17586 register in the final list objects containing class-wide interfaces;
17587 otherwise we incorrectly register the tag of the interface in the final
17589 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17590 generate the wrapper if the parent primitive is abstract. This is
17591 required to report the correct error message.
17592 (Expand_N_Subtype_Indication): Do validity checks on range
17593 (Clean_Task_Names): If an initialization procedure includes a call to
17594 initialize a task (sub)component, indicate that the procedure will use
17595 the secondary stack.
17596 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17597 compatibility for interfacing with CPP by default.
17598 (Expand_N_Object_Declaration): Only build an Adjust call when the
17599 object's type is a nonlimited controlled type.
17600 * exp_ch3.adb: Add with and use of Exp_Ch6.
17601 (Expand_N_Object_Declaration): Check for object initialization that is a
17602 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17603 Object_Declaration to the call.
17604 (Freeze_Type): When the designated type of an RACW was not frozen at the
17605 point where the RACW was declared, validate the primitive operations
17606 with respect to E.2.2(14) when it finally is frozen.
17607 (Build_Initialization_Call,Expand_Record_Controller): Rename
17608 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17609 return-by-reference has no meaning in Ada 2005.
17610 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17611 to register tag of the immediate ancestor interfaces in the
17612 run-time structure.
17613 (Init_Secondary_Tags): Moved to the specification to allow the
17614 initialization of extension aggregates with abstract interfaces.
17615 (Build_Master_Renaming): Make public, for use by function declarations
17616 whose return type is an anonymous access type.
17617 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17618 Insert_List_Before_And_Analyze after the generation of the specs
17619 associated with null procedures.
17620 (Expand_Tagged_Root): Update documentation in its specification.
17621 (Init_Secondary_Tags): Update documentation.
17622 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17623 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17624 then generate code to inherit the contents of the dispatch table
17625 directly from the ancestor.
17626 (Expand_Record_Controller): Insert controller component after tags of
17627 implemented interfaces.
17628 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17629 create null procedure overridings when null procedures are inherited
17631 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17632 declarations for overriding null primitives inherited from interfaces.
17633 (Is_Null_Interface_Procedure): New function in
17634 Make_Null_Procedure_Specs.
17635 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17636 immediate ancestor of a tagged type is an abstract interface type we
17637 must generate the specification of the predefined primitives associated
17638 with controlled types (because the dispatch table of the ancestor is
17639 null and hence these entries cannot be inherited). This is required to
17640 elaborate well the dispatch table.

17648 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
17650 (Expand_N_In): Do validity checks on range
17651 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17652 (Expand_N_Allocator): For "new T", if the object is constrained by
17653 discriminant defaults, allocate the right amount of memory, rather than
17654 the maximum for type T.
17655 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17656 when the allocator is initialized by a build-in-place call, since the
17657 allocator is already rewritten as a reference to the function result,
17658 and this prevents an unwanted duplication of the function call.
17659 Add with and use of Exp_Ch6.
17660 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17661 is a call to build-in-place function and apply
17662 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17663 untagged designated types).
17664 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17665 optimization if source or target is biased.
17666 (Expand_N_Allocator): Add comments for case of an allocator within a
17667 function that returns an anonymous access type designating tasks.
17668 (Expand_N_Allocator): apply discriminant checks for access
17669 discriminants of anonymous access types (AI-402, AI-416)

17674 Ed Schonberg <schonberg@adacore.com>
17676 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17678 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17679 (Expand_N_Assignment_Statement): Call
17680 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17681 build-in-place function call. Currently, this can happen only for
17682 assignments that come from aggregates.
17683 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17684 in order to alleviate the upward compatibility introduced by AI-318.
17685 (Expand_N_Extended_Return_Statement): Add support for handling the
17686 return object as a build-in-place result.
17687 (Expand_Non_Function_Return): Implement simple return statements nested
17688 within an extended return.
17689 (Enable_New_Return_Processing): Turn on the new processing of return
17691 (Expand_Non_Function_Return): For a return within an extended return,
17692 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17693 (Expand_N_Extended_Return_Statement): Implement AI-318
17694 (Expand_Simple_Function_Return): Ditto.
17695 (Expand_N_If_Statement): Handle new -gnatwt warning

17697 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17698 a protected object.
17699 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17700 validity checking of assignments to elementary record components.
17701 (Expand_N_Return_Statement): return Class Wide types on the secondary
17702 stack independantly of their controlled status since with HIE runtimes,
17703 class wide types are not potentially controlled anymore.
17705 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17708 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17709 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17710 it expects a block, procedure, or task. The return statement will get
17711 turned into a block, and Expand_Cleanup_Actions will happen then.

17715 Bob Duff <duff@adacore.com>
17716 Gary Dismukes <dismukes@adacore.com>
17718 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17720 (Expand_Inlined_Call): Tagged types are by-reference types, and
17721 therefore should be replaced by a renaming declaration in the expanded
17722 body, as is done for limited types.
17723 (Expand_Call): If this is a call to a function with dispatching access
17724 result, propagate tag from context.
17725 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17727 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17728 build-in-place when the right-hand side of an assignment is a
17729 build-in-place function call.
17730 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17731 of the explicit dereference of the allocator to the result subtype of
17732 the build-in-place function. This is needed to satisfy type checking
17733 in cases where the caller's return object is created by an allocator for
17734 a class-wide access type and the type named in the allocator is a
17736 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17737 conversion of the reference to the declared object to the result subtype
17738 of the build-in-place function. This is needed to satisfy type checking
17739 in cases where the declared object has a class-wide type. Also, in the
17740 class-wide case, change the type of the object entity to the specific
17741 result subtype of the function, to avoid passing a class-wide object
17742 without explicit initialization to the back end.
17743 (Register_Interface_DT_Entry): Moved outside the body of
17744 Freeze_Subprogram because this routine is now public; it is called from
17745 Check_Dispatching_Overriding to handle late overriding of abstract
17746 interface primitives.
17747 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17748 adding an implicit access actual on a call to a build-in-place function.
17749 (Expand_Actuals): Test for an actual parameter that is a call to a
17750 build-in-place function and apply
17751 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17752 (Is_Build_In_Place_Function): New function to determine whether an
17753 entity is a function whose calls should be handled as build-in-place.
17754 (Is_Build_In_Place_Function_Call): New function to determine whether an
17755 expression is a function call that should handled as build-in-place.
17756 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17757 calls to build-in-place functions as the initialization of an allocator.
17758 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17759 handling calls to build-in-place functions in contexts that do not
17760 involve init of a separate object (for example, actuals of subprogram
17762 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17763 handling calls to build-in-place functions as the initialization of an
17764 object declaration.
17765 (Detect_Infinite_Recursion): Add explicit parameter Process to
17766 instantiation of Traverse_Body to avoid unreferenced warning.
17767 (Check_Overriding_Inherited_Interfaces): Removed.
17768 (Register_Interface_DT_Entry): Code cleanup.
17769 (Register_Predefined_DT_Entry): Code cleanup.
17770 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17771 inlined statements if within a transient scope.
17772 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17773 formal parameters with occurrences of actuals in inlined body, establish
17774 visibility on the proper view of the actual's subtype for the body's
17776 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17777 compatibility mode and we have an imported CPP subprogram because
17778 for now we assume that imported CPP primitives correspond with
17779 objects whose constructor is in the CPP side (and therefore we
17780 don't need to generate code to register them in the dispatch table).
17781 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17782 aligned selected component.
17783 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17784 the actual of an in-mode parameter is a type conversion.
17785 (Expand_Actuals): If the call does not come from source and the actual
17786 is potentially misaligned, let gigi handle it rather than rejecting the
17787 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17788 Class Wide types as returning by reference independantly of their
17789 controlled status since with HIE runtimes class wide types are not
17790 potentially controlled anymore.
17792 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17794 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17795 references that are private components of the protected object.
17796 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
17797 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17798 instantiation to deal with warnings.
17799 (Initialize_Protection): If expression for priority is non-static, use
17800 System_Priority as its expected type, in case the expression has not
17803 2006-10-31 Robert Dewar <dewar@adacore.com>
17805 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17806 initialization of Homonym_Len.
17807 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17808 names from fully qualified name. Fixes problem of duplicate
17809 external names differing only in the presence of such a block name.
17811 2006-10-31 Thomas Quinot <quinot@adacore.com>
17812 Pablo Oliveira <oliveira@adacore.com>
17814 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17815 subprogram Ids, even if they are not yet assigned.
17816 (Build_Subprogram_Id): It is now this function that will take care of
17817 calling Assign_Subprogram_Ids if necessary.
17818 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17819 should be done only once they are assigned.
17820 (Build_From_Any_Function, case of tagged types): Add missing call to
17822 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17823 type for an RACW type.
17824 (Add_RACW_Features): When processing an RACW declaration for which the
17825 designated type is already frozen, enforce E.2.2(14) rules immediately.
17826 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17827 special reordering of controlling formals.
17829 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17830 associated stub type for an RACW type.
17832 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17834 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17835 fixed-point operations in an integer context, i.e. as operands of a
17836 conversion to an integer type, indicate that result must be rounded.
17838 2006-10-31 Robert Dewar <dewar@adacore.com>
17840 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17841 cases, pass the encoding method, since it is now required by the run
17844 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17845 assumption that Str'First = 1.
17846 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17847 it on to the Value_Wide_Wide_Character call.
17848 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17849 properly handles a string of the form quote-encoded_wide_char-quote.
17851 * s-wchcnv.adb: Minor reformatting
17853 2006-10-31 Javier Miranda <miranda@adacore.com>
17855 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17856 run-time membership test to ensure that the constructed object
17857 implements the target abstract interface.
17859 2006-10-31 Robert Dewar <dewar@adacore.com>
17861 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17862 Machine_Attribute pragma internally to implement the user pragma.
17863 Add processing for pragma Interface so that it is now completely
17864 equivalent to pragma Import.
17866 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17867 so that it can be applied to all entities, including record components
17868 and enumeration literals.
17869 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17870 priority ranges are correct, verify compatibility against task
17871 dispatching and locking policies, and if everything is correct an entry
17872 is added to the table containing priority specific dispatching entries
17873 for this compilation unit.
17874 (Delay_Config_Pragma_Analyze): Delay processing
17875 Priority_Specific_Dispatching pragmas because when processing the
17876 pragma we need to access run-time data, such as the range of
17877 System.Any_Priority.
17878 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17879 Allow pragma Unreferenced as a context item
17880 Add pragma Preelaborable_Initialization

17882 now syntactically and semantically equivalent to Import.
17883 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17884 insertion characters.
17885 Add handling for Pragma_Wide_Character_Encoding
17886 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17887 never supercedes a real restriction, and that a real restriction
17888 always supercedes a warning.
17889 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17896 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17897 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17898 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17900 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17901 type of the function containing a return statement, because the
17902 Return_Type field was removed. We now use the Return_Applies_To field.
17904 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17905 (Build_Task_Image_Decl): If procedure is not called from an
17906 initialization procedure, indicate that function that builds task name
17907 uses the sec. stack. Otherwise the enclosing initialization procedure
17908 will carry the indication.
17909 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17910 N_Object_Declaration instead.
17911 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17912 conditional dead code killed, and change implementation accordingly.
17913 (Insert_Actions): Add N_Return_Object_Declaration case.
17914 Correct comment to mention N_Extension_Aggregate node.
17915 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17916 attempts to save information for global variables which cannot be
17918 (Get_Current_Value_Condition): Handle conditions the other way round
17919 (constant on left). Also handle right operand of AND and AND THEN
17920 (Set_Current_Value_Condition): Corresponding changes
17921 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17922 (Get_Current_Value_Condition): Handle simple boolean operands
17923 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17924 (Get_Current_Value_Condition): If the variable reference is within an
17925 if-statement, does not appear in the list of then_statments, and does
17926 not come from source, treat it as being at unknown location.
17927 (Get_Current_Value_Condition): Enhance to allow while statements to be
17928 processed as well as if statements.
17929 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17931 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17932 of loop. This is safe now that we fixed Kill_Current_Values.
17933 (OK_To_Do_Constant_Replacement): Check whether current scope is
17934 Standard, before examining outer scopes.
17936 2006-10-31 Vincent Celier <celier@adacore.com>

17948 (Warn_Overlay): Supply missing continuation marks in error msgs
17949 (Freeze_Entity): Add check for Preelaborable_Initialization
17951 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17953 * g-expect.adb: Add Warnings (Off) to prevent new warning
17955 * lib-xref.adb: Add handling of Last_Assignment field
17956 (Generate_Reference): Centralize handling of pragma Obsolescent here
17957 (Generate_Reference): Accept an implicit reference generated for a
17958 default in an instance.
17959 (Generate_Reference): Accept a reference for a node that is not in the
17960 main unit, if it is the generic body corresponding to an subprogram
17963 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17965 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17967 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17969 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17970 use clauses, to avoid messages on packages used to qualify, and also
17971 to avoid messages from obsolescent units.
17972 (Warn_On_Useless_Assignments): Don't generate messages for imported
17973 and exported variables.
17974 (Warn_On_Useless_Assignments): New procedure
17975 (Output_Obsolescent_Entity_Warnings): New procedure
17976 (Check_Code_Statement): New procedure
17978 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag

17980 (Last_Assignment): New field for useless assignment warning
17982 2006-10-31 Olivier Hainque <hainque@adacore.com>
17984 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17985 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17987 2006-10-31 Bob Duff <duff@adacore.com>
17988 Robert Dewar <dewar@adacore.com>
17989 Ed Schonberg <schonberg@adacore.com>
17991 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17992 Ada 95 mode, because it violates the new rules for AI-318.
17994 * g-awk.ads: Use overloaded subprograms in every case where we used to
17995 have a default of Current_Session. This makes the code closer to be
17996 correct for both Ada 95 and 2005.
17998 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17999 code, relying on the fact that the compiler generates a warning
18000 instead of an error in -gnatg mode.
18002 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18003 E_Return_Statement entity kind.
18004 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18006 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18007 report an error if the reserved word abstract has been previously found.
18008 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18010 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18011 parenthesized range attribute usage
18012 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18014 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18015 in the syntax for extended_return_statement. This is not in the latest
18016 RM, but the ARG is expected to issue an AI allowing this.
18017 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18018 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18019 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18020 P_Return_Statement): Parse the new syntax for extended_return_statement.
18022 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18023 Output_End_Missing): Add error-recovery code for the new
18024 extended_return_statement syntax; that is, the new E_Return entry on
18027 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18028 limited to nonlimited, because otherwise we violate the new Ada 2005
18029 rules about returning limited types in function Create_AST_Handler in
18032 * sem.adb (Analyze): Add cases for new node kinds
18033 N_Extended_Return_Statement and N_Return_Object_Declaration.
18035 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18036 type is in the same category as type of context before applying check,
18037 to prevent anomalies in instantiations.
18038 (Resolve_Aggregate): Remove test for limited components in aggregates.
18039 It's unnecessary in Ada 95, because if it has limited components, then
18040 it must be limited. It's wrong in Ada 2005, because limited aggregates
18042 (Resolve_Record_Aggregate): Move check for limited types later, because
18043 OK_For_Limited_Init requires its argument to have been resolved.
18044 (Get_Value): When copying the component default expression for a
18045 defaulted association in an aggregate, use the sloc of the aggregate
18046 and not that of the original expression, to prevent spurious
18047 elaboration errors, when the expression includes function calls.
18048 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18049 were missing. We also didn't handle qualified expressions. Now also
18050 allow function calls. Use new common routine OK_For_Limited_Init.
18051 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18052 with space can upper case letter).
18054 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18055 Has_Static_Discriminants flag
18056 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18057 type with discriminants.
18058 (Process_Range_Expr_In_Decl): Do validity checks on range
18059 (Build_Discriminant_Constraints): Use updated form of
18060 Denotes_Discriminant.
18061 (Process_Subtype): If the subtype is a private subtype whose full view
18062 is a concurrent subtype, introduce an itype reference to prevent scope
18064 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18065 Record_Type_Declaration): The functionality of the subprograms
18066 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18067 is now performed by a single routine.
18068 (Build_Derived_Record_Type): If the type definition includes an explicit
18069 indication of limitedness, then the type must be marked as limited here
18070 to ensure that any access discriminants will not be treated as having
18071 a local anonymous access type.
18072 (Check_Abstract_Overriding): Issue a detailed error message when an
18073 abstract subprogram was not overridden due to incorrect mode of its
18075 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18076 synchronized private extension declarations. Verify that the ancestor is
18077 a limited or synchronized interface or in the generic case, the ancestor
18078 is a tagged limited type or synchronized interface and all progenitors
18079 are either limited or synchronized interfaces.
18080 Derived_Type_Declaration): Check for presence of private extension when
18081 dealing with synchronized formal derived types.
18082 Process_Full_View): Enchance the check done on the usage of "limited" by
18083 testing whether the private view is synchronized.
18084 Verify that a synchronized private view is completed by a protected or
18086 (OK_For_Limited_Init_In_05): New function.
18087 (Analyze_Object_Declaration): Move check for limited types later,
18088 because OK_For_Limited_Init requires its argument to have been resolved.
18089 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18090 in order to alleviate the upward compatibility introduced by AI-318.
18091 (Constrain_Corresponding_Record): If the constraint is for a component
18092 subtype, mark the itype as frozen, to avoid out-of-scope references to
18093 discriminants in the back-end.
18094 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18095 this subprogram against wrong sources.
18096 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18097 discriminant of limited type completed with a protected type, when the
18098 discriminant is used to constrain a private component of the type, and
18099 expansion is disabled.
18100 (Find_Type_Of_Object): Do not treat a return subtype that is an
18101 anonymous subtype as a local_anonymous_type, because its accessibility
18102 level is the return type of the enclosing function.
18103 (Check_Initialization): In -gnatg mode, turn the error "cannot
18104 initialize entities of limited type" into a warning.
18105 (OK_For_Limited_Init): Return true for generated nodes, since it
18106 sometimes violates the legality rules.
18107 (Make_Incomplete_Declaration): If the type for which an incomplete
18108 declaration is created happens to be the currently visible entity,
18109 preserve the homonym chain when removing it from visibility.
18110 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18111 inherited subprograms.
18112 (Access_Definition): If this is an access to function that is the return
18113 type of an access_to_function definition, context is a type declaration
18114 and the scope of the anonymous type is the current one.
18115 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18116 incomplete subtype to the set of private dependents of the original
18118 (Constrain_Discriminated_Type): Emit an error message whenever an
18119 incomplete subtype is being constrained.
18120 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18121 corresponding subtype of the full view of the original incomplete type.
18122 (Check_Incomplete): Properly detect invalid usage of incomplete types
18125 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18127 * g-catiio.ads, g-catiio.adb (Value): New function.

18136 Robert Dewar <dewar@adacore.com>
18138 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18139 handling executable extension manually and duplicating code.
18141 * make.adb: Implement new -S switch
18142 (Gnatmake): Use new function Osint.Executable_Name instead
18143 of handling executable extension manually.
18145 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18146 is specified, the executable name ends with this suffix.
18147 Take advantage of Osint.Executable_Name instead of duplicating code.
18149 * switch-m.adb: Recognize new gnatmake -S switch
18151 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18153 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18156 * makeusg.adb: Add line for gnatmake -S switch
18158 2006-10-31 Vincent Celier <celier@adacore.com>
18160 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18161 call it with -static-libgcc, as there are some platforms, such as
18162 Darwin, where one of these two switches is compulsory to link.
18164 2006-10-31 Vincent Celier <celier@adacore.com>
18166 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18167 instead of ADA_PROJECT_PATH, for the project path.
18168 (Gnatls): When displaying the project path directories, use host dir
18171 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18172 names in the project path, as absolute paths may correspond to
18173 multi-valued VMS logical names.
18175 2006-10-31 Vincent Celier <celier@adacore.com>
18177 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18178 absolute path name.
18179 (Locate_Regular_File): Ditto
18180 (Change_Dir): Remove, no longer used
18181 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18182 on Windows. Get it calling Get_Current_Dir.
18183 (OpenVMS): Remove imported boolean, no longer needed.
18184 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18185 (Pid_To_Integer): New function to convert a Process_Id to Integer
18187 2006-10-31 Thomas Quinot <quinot@adacore.com>
18189 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18190 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18192 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18195 2006-10-31 Robert Dewar <dewar@adacore.com>
18197 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
18198 initial letter o as a zero.

18202 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
18204 2006-10-31 Robert Dewar <dewar@adacore.com>
18206 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18208 (Layout_Variant_Record): Retrieve the discriminants from the entity
18209 rather than from the type definition, because in the case of a full
18210 type for a private type we need to take the discriminants from the
18212 (Layout_Component_List): When applying the Max operator to variants with
18213 a nonstatic size, check whether either operand is static and scale that
18214 operand from bits to storage units before applying Max.
18215 (Layout_Type): In VMS, if a C-convention access type has no explicit
18216 size clause (and does not inherit one in the case of a derived type),
18217 then the size is reset to 32 from 64.
18219 2006-10-31 Vincent Celier <celier@adacore.com>
18221 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18222 its file has already been loaded, according to the unit being loaded,
18223 not to the current value of Multiple_Unit_Index.
18225 2006-10-31 Thomas Quinot <quinot@adacore.com>
18226 Eric Botcazou <ebotcazou@adacore.com>

18261 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18263 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18264 Process_Body_Clauses): If the context of a body includes a use clause
18265 for P.Q then a with_clause for P in the same body is not redundant,
18266 even if the spec also has a with_clause on P.
18267 Add missing continuation mark to error msg
18268 (Build_Limited_Views): A limited view of a type is tagged if its
18269 declaration includes a record extension.
18270 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18271 node, even if the subunit has errors. This avoids malfunction by
18272 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18273 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18274 generation of obsolescent messages for with statements (cannot do
18275 this too early, or we cannot implement avoiding the messages in the
18276 case of obsolescent units withing obsolescent units).
18277 (Install_Siblings): If the with_clause is on a remote descendant of
18278 an ancestor of the current compilation unit, find whether there is
18279 a sibling child unit that is immediately visible.
18280 (Remove_Private_With_Clauses): New procedure, invoked after completing
18281 the analysis of the private part of a nested package, to remove from
18282 visibility the private with_clauses of the enclosing package
18284 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18285 now centralized in Generate_Reference.
18286 (Install_Limited_Context_Clauses): Remove superfluous error
18287 message associated with unlimited view visible through use
18288 and renamings. In addition, at the point in which the error
18289 is reported, we add the backslash to the text of the error
18290 to ensure that it is reported as a single error message.
18291 Use new // insertion for some continuation messages
18292 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18293 to create implicit with_clause for parent unit mentioned in original
18294 limited_with_clause.
18295 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18296 unit is a child unit. For ASIS queries.
18297 (Analyze_Subunit): If the subunit appears within a child unit, make all
18298 ancestor child units directly visible again.

18313 a formal object declaration with an access definition or a subtype mark
18314 with a null exclusion.
18315 (P_Generic_Association): Handle association with box, and others_choice
18316 with box, to support Ada 2005 partially parametrized formal packages.
18318 2006-10-31 Robert Dewar <dewar@adacore.com>
18319 Javier Miranda <miranda@adacore.com>
18321 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18322 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18323 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18324 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18325 private extensions.
18326 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18327 to P_Interface_Type_Definition.
18328 (P_Interface_Type_Definition): Addition of one formal to report an error
18329 if the reserved word abstract has been previously found.
18330 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18331 object renaming declaration with an access definition or subtype mark
18332 with a possible null exclusion.
18334 * par-ch9.adb: Minor error msg fix
18336 * par-load.adb: Add missing continuation mark to error msg

18351 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18354 2006-10-31 Vincent Celier <celier@adacore.com>
18356 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18357 on VMS, change "__" to '.' before checking the name.
18358 (Record_Ada_Source): Always add the source file name in the list of
18359 of sources, even if it is not the first time, as it is for another
18361 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18362 dot, instead of replacing only the first '_'.
18364 * prj-part.adb (Parse): Convert project file path to canonical form
18366 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18367 extended, the project id of the project extending it is recorded in its
18368 data, even when it has already been processed as an imported project.

18376 Robert Dewar <dewar@adacore.com>
18378 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18379 only a restriction warning is active for the given restriction. This is
18380 desirable because we do not want to modify code in the case where only
18382 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18383 causes overriding of real restrictions.
18384 Take advantage of new No_Restrictions constant.
18386 * raise.h: (__gnat_set_globals): Change profile.
18388 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18390 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18393 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18394 Move all the entities in obsolete package System.PolyORB_Interface to
18395 System.Partition_Interface.

18413 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18414 properly an attempt to apply Unchecked_Access to a protected operation.
18415 (OK_Self_Reference): New subprogram to check the legality of an access
18416 attribute whose prefix is the type of an enclosing aggregate.
18417 Generalizes previous mechanism to handle attribute references nested
18418 arbitrarily deep within the aggregate.
18419 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18420 can appear in an aggregate if this is a default-initialized aggregate
18421 for a self-referential type.

18426 (Stream_Attribute_Available): Implement using new subprogram from
18427 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18428 Has_Specified_Stream_Attribute flag.
18429 Disallow Storage_Size and Storage_Pool for access to subprogram
18430 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18431 access types of return subtypes in extended return statements. Remove
18432 accessibility checks on anonymous access types when Unchecked_Access is
18434 (Analyze_Attribute): Add support for the use of 'Class to convert
18435 a class-wide interface to a tagged type.
18436 Add support for the attribute Priority.
18437 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18438 whether the designated type is discriminated with a constrained partial
18439 view and require static matching in that case.
18440 Add local variable Des_Btyp. The Designated_Type
18441 of an access to incomplete subtype is either its non-limited view if
18442 coming from a limited with or its etype if regular incomplete subtype.
18444 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18445 Fix predicate to identify and allow cases of (expander-generated)
18446 references to tag of designated object of a RACW.
18447 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18448 non-static, and therefore cannot appear as a primary in a preelaborable
18450 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18451 Has_Read_Write_Attributes.
18452 (Has_Read_Write_Attributes): Reimplement in termes of
18453 Has_Stream_Attribute_Definition.
18454 (Missing_Read_Write_Attributes): When checking component types in a
18455 record, unconditionally call Missing_Read_Write_Attributes recursively
18456 (remove guard checking for Is_Record_Type / Is_Access_Type).
18458 2006-10-31 Robert Dewar <dewar@adacore.com>
18460 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18461 useless assignments here and conditionalize it on absence of exception
18463 (Analyze_Exception_Handlers): Small code reorganization of error
18464 detection code, for new handling of formal packages.
18466 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18467 Hristian Kirtchev <kirtchev@adacore.com>
18469 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18470 that has been constant-folded, preserve information of original tree,
18472 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18473 generated private extension declaration if the formal derived type is
18474 synchronized. Carry synchronized present over to the generated private
18476 (Validate_Derived_Type_Instance): Ensure that the actual of a
18477 synchronized formal derived type is a synchronized tagged type.
18478 (Instantiate_Formal_Package): When creating the instantiation used to
18479 validate the actual package of a formal declared without a box, check
18480 whether the formal itself depends on a prior actual.
18481 (Instantiate_Formal_Subprogram): Create new entities for the defining
18482 identifiers of the formals in the renaming declaration, for ASIS use.
18483 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18484 a renaming declaration or a subtype declaration for an actual in an
18485 instance, capture location information of declaration in generic, for
18487 (Instantiate_Formal_Package): Add comments on needed additional tests.
18488 AI-317 (partial parametrization) is fully implemented.
18489 (Validate_Private_Type_Instance): Add check for actual which
18490 must have preelaborable initialization
18491 Use new // insertion for some continuation messages
18492 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18493 Default_Expression. Add type retrieval when the declaration has an
18494 access definition. Update premature usage of incomplete type check.
18495 (Check_Access_Definition): New subsidiary routine. Check whether the
18496 current compilation version is Ada 05 and the supplied node has an
18498 (Instantiate object): Alphabetize local variables. Handle the creation
18499 of new renaming declarations with respect to the kind of definition
18500 used - either an access definition or a subtype mark. Guard against
18501 unnecessary error message in the context of anonymous access types after
18502 they have been resolved. Add check for required null exclusion in a
18503 formal object declaration.
18504 (Switch_View): A private subtype of a non-private type needs to be
18505 switched (the base type can have been switched without its private
18506 dependents because of the last branch of Check_Private_View.
18507 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18509 (Instantiate_Type): Emit an error message whenever a class-wide type of
18510 a tagged incomplete type is used as a generic actual.
18511 (Find_Actual_Type): Extend routine to handle a component type in a child
18512 unit that is imported from a formal package in a parent.
18513 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18514 agree on constrainedness, rather than checking against ultimate ancestor
18515 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18516 generic body, for navigation purposes.
18518 2006-10-31 Robert Dewar <dewar@adacore.com>
18519 Thomas Quinot <quinot@adacore.com>
18521 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18523 (New_Stream_Subprogram): When processing an attribute definition clause
18524 for a stream-oriented subprogram, record an entity node occurring at
18525 the point of clause to use for checking the visibility of the clause,
18526 as defined by 8.3(23) as amended by AI-195.
18527 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18528 New_Stream_Function and New_Stream_Procedure.
18529 (New_Stream_Function, New_Stream_Procedure): Removed.
18530 (Analyze_Attribute_Definition_Clause, case Address): Check new
18531 Alignment_Check check

18534 Javier Miranda <miranda@adacore.com>
18535 Robert Dewar <dewar@adacore.com>
18537 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18538 generate the same errors compiling under -gnatc.
18539 (Try_Object_Operation): If no candidate interpretation succeeds, but
18540 there is at least one primitive operation with the right name, report
18541 error in call rather than on a malformed selected component.
18542 (Analyze_Selected_Component): If the prefix is an incomplete type from
18543 a limited view, and the full view is available, use the full view to
18544 determine whether this is a prefixed call to a primitive operation.
18545 (Operator_Check): Verify that a candidate interpretation is a binary
18546 operation before checking the type of its second formal.
18547 (Analyze_Call): Add additional warnings for function call contexts not
18549 (Analyze_Allocator): Move the check for "initialization not allowed for
18550 limited types" after analyzing the expression. This is necessary,
18551 because OK_For_Limited_Init looks at the structure of the expression.
18552 Before analysis, we don't necessarily know what sort of expression it
18553 is. For example, we don't know whether F(X) is a function call or an
18554 indexed component; the former is legal in Ada 2005; the latter is not.
18555 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18556 were missing. We also didn't handle qualified expressions. Now also
18557 allow function calls. Use new common routine OK_For_Limited_Init.
18558 (Analyze_Type_Conversion): Do not perform some legality checks in an
18559 instance, because the error message will be redundant or spurious.
18560 (Analyze_Overloaded_Selected_Component): Do not do style check when
18561 setting an entity, since we do not know it is the right entity yet.
18562 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18563 (Analyze_Overloaded_Selected_Component): Same change
18564 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18565 since regular incomplete subtypes are transformed into corresponding
18566 subtypes of their full views.
18567 (Complete_Object_Operation): Treat name of transformed subprogram call
18568 as coming from source, for browsing purposes.
18569 (Try_Primitive_Operation): If formal is an access parameter, compare
18570 with base type of object to determine whether it is a primitive
18572 (Operator_Check): If no interpretation of the operator matches, check
18573 whether a use clause on any candidate might make the operation legal.
18574 (Try_Class_Wide_Operation): Check whether the first parameter is an
18575 access type whose designated type is class-wide.

18582 warn on infinite loops.
18583 Add \\ to some continuation messages
18584 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18585 (Process_Bounds): If the bounds are integer literals that result from
18586 constant-folding, and they carry a user-defined type, preserve that type
18587 rather than treating this as an integer range.
18588 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18589 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18590 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18591 left hand side of assignment.
18592 (Analyze_Assignment): Add suport to manage assigments to the attribute
18593 priority of a protected object.
18594 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18595 not just identifiers.
18596 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18597 or AND THEN for possible tracking.
18598 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18599 case of while loops so we can track values in the loop body.

18602 Hristian Kirtchev <kirtchev@adacore.com>
18603 Bob Duff <duff@adacore.com>
18605 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18606 procedure cannot be a protected operation (it is a basic_declaration,
18607 not a subprogram_declaration).
18608 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18609 Subp. Add logic for entry processing.
18610 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18611 Determine whether an entry or subprogram of a protected or task type
18612 override an inherited primitive of an implemented interface.
18613 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18614 Update the actual used in calls to Check_Overriding_Indicator.
18615 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18616 generate the proper reference to the parent unit, for cross-reference.
18617 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18619 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18620 (Add_Extra_Formal): Revise procedure to allow passing in associated
18621 entity, scope, and name suffix, and handle setting of the new
18622 Extra_Formals field.
18623 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18624 pass new parameters. Add support for adding the new extra access formal
18625 for functions whose calls are treated as build-in-place.
18626 (Analyze_A_Return_Statement): Correct casing in error message.
18627 Move Pop_Scope to after Analyze_Function_Return, because an extended
18628 return statement really is a full-fledged scope. Otherwise, visibility
18629 doesn't work right. Correct use of "\" for continuation messages.
18630 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18631 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18632 the node doesn't get properly marked as analyzed.
18633 (Analyze_Subprogram_Body): If subprogram is a function that returns
18634 an anonymous access type that denotes a task, build a Master Entity
18636 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18637 proper usage of null exclusion in a result definition.
18638 (Process_Formals): Code cleanup and new error message.
18639 (Process_Formals): Detect incorrect application of null exclusion to
18641 (Conforming_Types): Handle conformance between [sub]types and itypes
18642 generated for entities that have null exclusions applied to them.
18643 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18644 base type is an access subtype. This case arrises with null exclusions.
18645 (New_Overloaded_Entity): Do not remove the overriden entity from the
18646 homonym chain if it corresponds with an abstract interface primitive.
18647 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18648 call to the synthesized predicate Is_Incomplete_Type.
18649 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18651 (Analyze_Subprogram_Declaration): Check that abstract interface
18652 primitives are abstract or null.
18653 (Analyze_Subprogram_Specification): Remove previous check for abstract
18654 interfaces because it was not complete.
18655 (Has_Interface_Formals): Removed.

18658 Javier Miranda <miranda@adacore.com>
18660 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18661 of Analyze_Package_Body, to create Itype references for anonymous
18662 access types created in the package declaration, whose designated types
18663 may have only a limited view.
18664 (Analyze_Package_Specification): For the private part of a nested
18665 package, install private_with_clauses of enclosing compilation unit if
18666 we are in its visible part.
18667 (Declare_Inherited_Private_Subprograms): Complete barrier
18668 to ensure that the primitive operation has an alias to some parent
18669 primitive. This is now required because, after the changes done for the
18670 implementation of abstract interfaces, the contents of the list of
18671 primitives has entities whose alias attribute references entities of
18672 such list of primitives.
18673 (Analyze_Package_Specification): Simplify code that handles parent units
18674 of instances and formal packages.
18675 (Uninstall_Declarations): Check the convention consistency among
18676 primitive overriding operations of a tagged record type.

18687 (Analyze_Generic_Renaming): Same fix
18688 (Use_One_Package): Do not take into account the internal entities of
18689 abstract interfaces during the analysis of entities that are marked
18690 as potentially use-visible.
18691 (Find_Type): Handle the case of an attribute reference for
18692 implementation defined attribute Stub_Type (simply let the analysis of
18693 the attribute reference rewrite it).
18694 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18695 type that appears in a Use_Type clause.
18696 (Analyze_Object_Renaming): Add support for renaming of the Priority
18698 (Find_Type): In Ada 2005, a task type can be used within its own body,
18699 when it appears in an access definition.
18700 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18701 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18702 in a formal object declaration or in a subtype declaration.
18703 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18704 (Check_Null_Exclusion): New local routine to
18705 Analyze_Subprogram_Renaming. Check whether the formals and return
18706 profile of a renamed subprogram have required null exclusions when
18707 their counterparts of the renaming already impose them.
18708 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18709 Determine whether an entity is inside a generic scope.
18710 (In_Open_Scope): First pass of documentation update.
18711 (Find_Expanded_Name): Add support for shadow entities associated with
18712 limited withed packages. This is required to handle nested packages.
18713 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18714 that makes a renaming of a limited withed package illegal.

18721 (Analyze_Task_Definition): Ditto.
18722 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18723 (Check_Overriding_Indicator): To find overridden interface operation,
18724 examine only homonyms that have an explicit subprogram declaration, not
18725 inherited operations created by an unrelated type derivation.
18726 (Check_Overriding_Indicator): When checking for the presence of "null"
18727 in a procedure, ensure that the queried node is a procedure
18729 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18730 type when the formal is an access to variable.
18731 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18732 (Analyze_Task_Type): Same addition

18742 inherited from an interface ancestor by another interface in the
18743 context of an instance as 'late'.
18744 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18745 of a call to a function that dispatches on access result.
18746 (Check_Dispatching_Operation): In case of late overriding of a primitive
18747 that covers abstract interface subprograms we register it in all the
18748 secondary dispatch tables associated with abstract interfaces.
18749 (Check_Dispatching_Call): Add check that a dispatching call is not made
18750 to a function with a controlling result of a limited type. This is a
18751 current implementation restriction.
18752 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18753 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18754 argument is an interface type that is a generic formal.
18755 (Is_Interface_Subprogram): Removed.
18756 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18757 operation, check the formals to handle the case in which it is
18758 associated with an abstract interface type.

18778 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18779 subprogram type to provide better diagnostics in case of ambiguity.
18780 (Covers): Handle coverage of formal and actual anonymous access types in
18781 the context of generic instantiation.
18782 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18783 abstract interface types; this is required to handle concurrent types
18784 with discriminants and abstract interface types.
18785 (Covers): Include type coverage of both regular incomplete subtypes and
18786 incomplete subtypes of incomplete type visibles through a limited with

18799 (Unqualify): New function for removing zero or more levels of
18800 qualification from an expression. There are numerous places where this
18801 ought to be used, but we currently only deal properly with zero or one
18803 (In_Instance); The analysis of the actuals in the instantiation of a

18885 (Return_Object_Declarations): New field to support extended return
18887 (N_Extended_Return_Statement): New node for extended_return_statement
18889 (N_Return_Object_Declaration): New node for part of

19574 we must pass the work to the expander to generate the required code to
19575 evaluate the conversion at run-time.
19576 (Resolve_Equality_Op): Do not apply previous

19916 other basic tools. The full version that includes the Ada 2005 stuff

20257 same as the length of the version string computed from Gnatvsn.
20258 (Search_Directory_Present): New Boolean flag for the compiler.
20259 Define Tree_Version_String as a dynamic string.
20260 (Default_Stack_Size): new variable, used to handle switch -d.
20263 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
20264 only for main unit.
20265 Add pragma Ada_2005 (synonym for Ada_05)
20266 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20267 were not always properly handled previously.
20269 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
20270 explicit Ada_95 to Ada_2005.
20272 2006-02-13 Javier Miranda <miranda@adacore.com>
20273 Robert Dewar <dewar@adacore.com>
20274 Ed Schonberg <schonberg@adacore.com>
20276 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
20277 against errors in the source program: a private types for which the
20278 corresponding full type declaration is missing and pragma CPP_Virtual
20280 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
20281 (Is_Known_Null): New flag
20282 (Has_Pragma_Pure): New flag
20283 (No_Return): Present in all entities, set only for procedures
20284 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20285 explicitly declared limited.
20286 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20287 entities. Only used for component marked Is_Tag. If present it stores
20288 the Offset_To_Top function used to provide this value in tagged types
20289 whose ancestor has discriminants.
20291 * exp_ch2.adb: Update status of new Is_Known_Null flag
20293 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
20295 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
20296 the categorization sense if Is_Pure was set by pragma Pure_Function.
20298 2006-02-13 Quentin Ochem <ochem@adacore.com>
20299 Olivier Hainque <hainque@adacore.com>
20301 * bindusg.adb: Updated documentation for -d and -D switches.
20303 * raise.h (__gnat_set_globals): added new parameter for
20304 Default_Stack_Size.
20306 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
20307 (__gnat_handle_vms_condition): Adjust context before raise.
20308 (__gnat_install_handler): Restore the global vector setup for GCC
20309 versions before 3.4, as the frame based circtuitry is not available
20311 (__gnat_set_globals): added a parameter default_stack_size
20312 (__gl_default_stack_size): new variable.
20314 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20316 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20317 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20318 does not exist in the Ada RM.
20319 (Compatible_Int_Bounds): Determine whether two integer range bounds
20320 are of equal length and have the same start and end values.
20321 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20322 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20323 aggregate when it is part of an object declaration.
20324 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20325 constrains discriminants of its parent, add explicitly the discriminant
20326 constraints of the ancestor by retrieving them from the
20327 stored_constraint of the parent.
20329 2006-02-13 Robert Dewar <dewar@adacore.com>
20331 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20332 attribute Mechanism_Code is applied to renamed subprogram, modify
20333 prefix to point to base subprogram.
20334 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20336 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20337 renamed subprograms so that the front-end must replace the prefix
20340 2006-02-13 Javier Miranda <miranda@adacore.com>
20341 Gary Dismukes <dismukes@adacore.com>
20343 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20344 availability of RE_Interface_Tag.
20345 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20346 (Freeze_Record_Type): Do not generate the tables associated with
20347 timed and conditional dispatching calls through synchronized
20348 interfaces if compiling under No_Dispatching_Calls restriction.
20349 When compiling for Ada 2005, for a nonabstract
20350 type with a null extension, call Make_Controlling_Function_Wrappers
20351 and insert the wrapper function declarations and bodies (the latter
20352 being appended as freeze actions).
20353 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20354 predefined primitives associated with timed and conditional
20355 dispatching calls through synchronized interfaces if we are
20356 compiling under No_Dispatching_Calls.
20357 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20358 service is available before generating a call.
20359 (Make_Controlling_Function_Wrappers): New procedure.
20360 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20361 access-to-limited-interfaces because they can be used to reference
20362 tasks that implement such limited interface.
20363 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20364 procedure spec and body of the Offset_To_Top function that is generated
20365 when the parent of a type with discriminants has secondary dispatch
20367 (Init_Secondary_Tags): Handle the case in which the parent of the type
20368 containing secondary dispatch tables has discriminants to generate the
20369 correct arguments to call Set_Offset_To_Top.
20370 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20372 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20373 Add Wide_[Wide_]Expanded_Name.
20374 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20375 the same functionality of Get_Prim_Op_Address but applied to predefined
20376 primitive operations because the pointers to the predefined primitives
20377 are now saved in a separate table.
20378 (Parent_Size): Modified to get access to the separate table of primitive
20379 operations or the parent type.
20380 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20381 functionality of Set_Prim_Op_Address but applied to predefined primitive
20383 (Set_Signature): New subprogram used to store the signature of a DT.
20384 (Displace): If the Offset_To_Top value is not static then call the
20385 function generated by the expander to get such value; otherwise use
20386 the value stored in the table of interfaces.
20387 (Offset_To_Top): The type of the actual has been changed to Address to
20388 give the correct support to tagged types with discriminants. In this
20389 case this value is stored just immediately after the tag field.
20390 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20391 offset_to_top value is static and hence pass this value to the run-time
20392 to store it in the table of interfaces, or else if this value is dynamic
20393 and then pass to the run-time the address of a function that is
20394 generated by the expander to provide this value for each object of the
20397 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20398 (Default_Prim_Op_Count): New entity
20399 (Get_Predefined_Prim_Op_Address): New entity
20400 (Set_Predefined_Prim_Op_Address): New entity
20401 (RE_Set_Signature): New entity
20403 2006-02-13 Thomas Quinot <quinot@adacore.com>
20404 Ed Schonberg <schonberg@adacore.com>
20406 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20407 Make_Adjust_Call done for a newly-allocated object.
20409 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20410 in a subprogram are wrapped in a cleanup block, indicate that the
20411 subprogram contains an inner block with an exception handler.
20412 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20413 Adjust call is for a newly-allocated object. In that case we must not
20414 assume that the finalization list chain pointers are correct (since they
20415 come from a bit-for-bit copy of the original object's pointers) so if
20416 the attach level would otherwise be zero (no change), we set it to 4
20417 instead to cause the pointers to be reset to null.
20419 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20420 reset chain pointers to null.
20422 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20424 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20425 string, and the context requires a loop for the assignment (e.g.
20426 because the left-hand side is packed), generate a unique name for the
20427 temporary that holds the string, to prevent spurious name clashes.
20429 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20430 Javier Miranda <miranda@adacore.com>
20431 Robert Dewar <dewar@adacore.com>
20432 Gary Dismukes <dismukes@adacore.com>
20434 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20435 return unconstrained arrays.
20437 (Expand_Call): An indirect call through an access parameter of a
20438 protected operation is not a protected call.
20439 Add circuit to raise CE in Ada 2005 mode following call
20440 to Raise_Exception.
20441 (Register_DT_Entry): Do nothing if
20442 the run-time does not give support to abstract interfaces.
20443 (Freeze_Subprogram): In case of dispatching operations, do not generate
20444 code to register the operation in the dispatch table if the source
20445 is compiled with No_Dispatching_Calls.
20446 (Register_Predefined_DT_Entry): Generate code that calls the new
20447 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20448 Set_Prim_Op_Address.
20450 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20451 on array assignments if the right-hand side is a function call that has
20452 been inlined. Check is performed on the assignment in the block.
20453 (Process_Bounds): If bounds and range are overloaded, apply preference
20454 rule for root operations to disambiguate, and diagnose true ambiguity.
20455 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20456 a tag-indeterminate right-hand side even when Expander_Active is True.
20457 Needed to ensure that dispatching calls to T'Input are allowed and
20458 get the tag of the target class-wide object.
20460 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20461 an inherited primitive operation that already overrides several
20462 abstract interface primitives. For transitivity, the new entity must
20463 also override all the abstract interface primitives covered by the
20464 inherited overriden primitive.
20465 Emit warning if new entity differs from homograph in same scope only in
20466 that one has an access parameter and the other one has a parameter of
20467 a general access type with the same designated type, at the same
20468 position in the signature.
20469 (Make_Inequality_Operator): Use source locations of parameters and
20470 subtype marks from corresponding equality operator when creating the
20471 tree structure for the implicit declaration of "/=". This does not
20472 change anything in behaviour except that the decoration of the
20473 components of the subtree created for "/=" allows ASIS to get the
20474 string images of the corresponding identifiers.
20475 (Analyze_Return_Statement): Remove '!' in warning message.
20476 (Check_Statement_Sequence): Likewise.
20477 (Analyze_Subprogram_Body): For an access parameter whose designated type
20478 is an incomplete type imported through a limited_with clause, use the
20479 type of the corresponding formal in the body.
20480 (Check_Returns): Implicit return in No_Return procedure now raises
20481 Program_Error with a compile time warning, instead of beging illegal.
20482 (Has_Single_Return): Function returning unconstrained type cannot be
20483 inlined if expression in unique return statement is not an identifier.
20484 (Build_Body_To_Inline): It is possible to inline a function call that
20485 returns an unconstrained type if all return statements in the function
20486 return the same local variable. Subsidiary procedure Has_Single_Return
20487 verifies that the body conforms to this restriction.
20489 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20490 same type, and one of them is of an anonymous access type, convert
20491 the other operand to it, so that this is a valid binary operation for
20493 (Resolve_Type_Conversion): Handle subtypes of protected types and
20494 task types when accessing to the corresponding record type.
20495 (Resolve_Allocator): Add '\' in 2-line warning message.
20496 Remove '!' in warning message.
20497 (Resolve_Call): Add '\' in 2-line warning message.
20498 (Valid_Conversion): Likewise.
20499 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20500 resulting type may be an access type with an implicit dereference.
20501 Obtain the proper component from the designated type.
20502 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20503 given by an expanded name with prefix Standard, when the operands are
20504 of an anonymous access type.
20505 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20506 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20507 prefix of the expression is not of an incomplete type. Allows full
20508 diagnoses of all semantic errors.
20509 (Resolve_Actuals): If the actual is an allocator whose directly
20510 designated type is a class-wide interface we build an anonymous
20511 access type to use it as the type of the allocator. Later, when
20512 the subprogram call is expanded, if the interface has a secondary
20513 dispatch table the expander will add a type conversion to force
20514 the displacement of the pointer.
20515 (Resolve_Call): If a function that returns an unconstrained type is
20516 marked Inlined_Always and inlined, the call will be inlined and does
20517 not require the creation of a transient scope.
20518 (Check_Direct_Boolean_Op): Removed
20519 (Resolve_Comparison_Op): Remove call to above
20520 (Resolve_Equality_Op): Remove call to above
20521 (Resolve_Logical_Op): Inline above, since this is only call.
20522 (Valid_Conversion): Handle properly conversions between arrays of
20523 convertible anonymous access types.
20526 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20527 the literal in an unchecked conversion, because GCC 4.x needs a static
20528 value for a string bound.
20530 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20531 Hristian Kirtchev <kirtchev@adacore.com>
20533 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20534 components of the corresponding record, take into account component
20535 definitions that are access definitions.
20536 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20537 procedure is not considered a dispatching call and will be expanded
20540 2006-02-13 Javier Miranda <miranda@adacore.com>
20542 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20543 controlling argument of the dispatching call is an abstract interface
20544 class-wide type then we use it directly.
20545 Check No_Dispatching_Calls restriction.
20546 (Default_Prim_Op_Position): Remove the code that looks for the last
20547 entity in the list of aliased subprograms. This code was wrong in
20549 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20550 when the source is compiled with the No_Dispatching_Calls restriction.
20551 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20552 if we are compiling with restriction No_Dispatching_Calls.
20553 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20554 subprograms if we are compiling under No_Dispatching_Calls restriction.
20555 (Make_DT): Generate a dispatch table with a single dummy entry if
20556 we are compiling with the No_Dispatching_Calls restriction. In
20557 addition, in this case we don't generate code that calls to the
20558 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20559 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20560 of this subprogram if compiling with the No_Dispatching_Calls
20562 (Expand_Type_Conversion): Instead of using the actual parameter,
20563 the argument passed as parameter to the conversion function was
20564 erroneously referenced by the expander.
20565 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20566 Set_Predefined_Primitive_Op_Address and Set_Signature.
20567 (Expand_Dispatching_Call): Generate call to
20568 Get_Predefined_Prim_Op_Address for predefined primitives.
20569 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20570 predefined primitives.
20571 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20572 primitives we reserve one dummy entry to ensure that the tag does not
20573 point to some memory that is associated with some other object. In
20574 addition, remove all the old code that generated the assignments
20575 associated with the signature of the dispatch table and replace them
20576 by a call to the new subprogram Set_Signature.
20577 (Set_All_DT_Position): Change the algorithm because now we have a
20578 separate dispatch table associated with predefined primitive operations.
20579 (Expand_Interface_Conversion): In case of non-static offset_to_top
20580 add explicit dereference to get access to the object after the call
20581 to displace the pointer to the object.
20582 (Expand_Interface_Thunk): Modify the generation of the actual used
20583 in the calls to the run-time function Offset_To_Top to fulfil its
20585 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20587 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20589 * exp_dist.adb (Copy_Specification): For access parameters, copy
20590 Null_Exclusion flag, which will have been set for stream subprograms
20593 2006-02-13 Pascal Obry <obry@adacore.com>
20595 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20596 previous implementation was using the C runtime spawnve routine but
20597 the corresponding wait was using directly the Win32 API. This was
20598 causing some times a lock when waiting for an event using
20599 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20600 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20601 API fixes this problem.
20603 2006-02-13 Robert Dewar <dewar@adacore.com>
20605 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
20608 2006-02-13 Thomas Quinot <quinot@adacore.com>

20612 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
20613 array reference that is an explicit dereference, mark the converted
20614 (packed) array reference as analyzed to prevent a forthcoming
20615 reanalysis from resetting its type to the original (non-packed) array
20618 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20619 Javier Miranda <miranda@adacore.com>
20620 Eric Botcazou <ebotcazou@adacore.com>
20622 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20623 Is_Predefined_Primitive_Operation): When
20624 searching for the predefined equality operator, verify that operands
20625 have the same type.
20626 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20627 for the last entity in the list of aliased subprograms. This code
20628 was wrong in case of renamings.
20629 (Set_Renamed_Subprogram): New procedure
20630 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20631 Exp_Type constant computed when entering this subprogram.
20632 (Known_Null): New function
20633 (OK_To_Do_Constant_Replacement): New function
20634 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20635 (Side_Effect_Free): An attribute reference 'Input is not free of
20636 side effect, unlike other attributes that are functions. (from code
20638 (Remove_Side_Effects): Expressions that involve packed arrays or records
20639 are copied at the point of reference, and therefore must be marked as
20640 renamings of objects.
20641 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20642 not a dispatching operation.
20645 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20646 elementary types in all cases.
20648 2006-02-13 Javier Miranda <miranda@adacore.com>
20650 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20651 task types when accessing to the corresponding record type.
20652 Remove '!' in warning message.
20654 2006-02-13 Olivier Hainque <hainque@adacore.com>
20656 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20657 to avoid useless and space inefficient overalignments on targets where
20658 Max_Alignment is larger than 16.
20660 2006-02-13 Pascal Obry <obry@adacore.com>
20662 * g-catiio.adb (Sec_Number): New type used to compute the number of
20663 seconds since 1-1-1970.
20664 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20665 negative numbers (years, months...) it is better to have a Natural here.
20667 (Image) [Number]: Change parameter from Long_Integer to Number.
20668 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20669 overflow for dates past year 2038.
20671 2006-02-13 Matthew Heaney <heaney@adacore.com>
20673 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20676 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20678 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20680 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20681 finalization can occur normally.
20683 2006-02-13 Vincent Celier <celier@adacore.com>
20685 * gnatcmd.adb (Rules_Switches): New table
20686 (Add_To_Rules_Switches): New procedure
20687 (GNATCmd): For command CHECK, put all options following "-rules" in the
20688 Rules_Switches table. Append these -rules switches after the -cargs
20691 2006-02-13 Robert Dewar <dewar@adacore.com>
20693 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20694 These two cases were generating incorrect output, and if this unit
20695 was built with checks on, generated a discriminant mismatch constraint
20698 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20699 Robert Dewar <dewar@adacore.com>
20701 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20702 view is an array type, indicate the component type as well, for
20703 navigation purposes.
20704 (Generate_Reference): Don't consider array ref on LHS to be a case
20705 of violating pragma Unreferenced.
20706 Do not give Ada 2005 warning except on real reference.
20708 2006-02-13 Vincent Celier <celier@adacore.com>
20710 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20711 main source, add switch -mdebug-main=_ada_ so that the executable can
20712 be debugged by the standard VMS debugger.
20713 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20714 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20715 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20716 of the last source, as the binding and linking phases are never
20718 Set all executable obsolete when rebuilding a library.
20720 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20723 2006-02-13 Javier Miranda <miranda@adacore.com>
20726 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20727 code to improve the error message reported when the program has
20728 declarations of abstract interface types and it is not compiled with
20729 the -gnat05 switch.
20730 (P_Access_Definition): Reorganize the code to improve the error
20731 message reported when the new Ada 2005 syntax for anonymous
20732 access types is used and the program is not compiled with the

20756 unknown, use the location of the project to report the error.
20757 (When_No_Sources): New global variable
20758 (Report_No_Ada_Sources): New procedure
20759 (Check): New parameter When_No_Sources. Set value of global variable

20762 (Get_Sources_From_File): Ditto
20763 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20766 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20767 Call Prj.Proc.Process with parameter When_No_Sources.
20769 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20770 Call Recursive_Check with parameter When_No_Sources.

20785 When removing nodes (attributes Source_Dirs, Source_Files,
20786 Source_List_File and package Naming), save the comments and attach the
20787 saved comments to the newly created nodes.
20788 Do not add a with clause for the naming package if one already exists.

20797 aliased entities to look for the overriden abstract interface
20799 (Is_Interface_Subprogram): Complete documentation.
20800 (Check_Dispatching_Operation): Do not generate code to register the
20801 operation in the dispatch table if the source is compiled with
20802 restriction No_Dispatching_Calls.

20804 No_Return procedure with procedure that is not No_Return
20805 (Check_Dispatching_Call): Suppress the check for an abstract operation
20806 when the original node of an actual is a tag-indeterminate attribute
20807 call, since the attribute, which must be 'Input, can never be abstract.
20808 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20809 call to the Input attribute (even when rewritten).
20810 (Propagate_Tag): Augment comment to indicate the possibility of a call
20811 to an Input attribute.
20813 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow

20823 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20825 2006-02-13 Javier Miranda <miranda@adacore.com>
20827 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20828 handles default-initialized components to keep separate the management
20829 of this feature but also avoid the unrequired resolution and
20830 expansion of components that do not have partially initialized
20832 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20833 (Check_Bounds): Likewise.
20834 (Check_Length): Likewise.
20836 2006-02-13 Javier Miranda <miranda@adacore.com>
20837 Ed Schonberg <schonberg@adacore.com>
20839 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20840 abstract interface type call analyze_and_resolve to expand the type
20841 conversion into the corresponding displacement of the
20842 reference to the base of the object.
20843 (Eval_Attribute, case Width): For systems where IEEE extended precision
20844 is supported, the maximum exponent occupies 4 decimal digits.
20845 (Accessibility_Message): Add '\' in 2-line warning message.
20846 (Resolve_Attribute): Likewise.
20847 (case Attribute_Access): Significantly revise checks
20848 for illegal access-to-subprogram Access attributes to properly enforce
20849 the rules of 3.10.2(32/2).
20850 Diagnose use of current instance with an illegal attribute.
20852 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20854 (Enclosing_Generic_Unit): New function to return a node's innermost
20855 enclosing generic declaration node.
20856 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20857 (Type_Access_Level): The accessibility level of anonymous acccess types
20858 associated with discriminants is that of the current instance of the
20859 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20860 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20861 (Kill_Current_Values_For_Entity): New function
20862 (Enter_Name): Change formal type to Entity_Id
20864 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>

20868 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20869 Analyze_Compilation_Unit.
20870 Detect and warn on redundant with clauses detected in a package spec
20871 and/or body when -gnatwr is used.
20872 (Analyze_Context): Analyze config pragmas before other items
20873 (Install_Context_Items): Don't analyze config pragmas here
20874 (Install_Limited_Withed_Unit): Set limited entity of package in
20875 with_clause so that cross-reference information or warning messages on
20876 unused packages can be properly generated
20877 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20878 has Error_Posted set. Prevent infinite loops in illegal programs.
20879 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20880 to the point of the error test requiring the current unit to be private.
20881 This ensures that private with clauses are not exempted from the basic
20882 checking for being a descendant of the same library unit parent as a
20883 withed private descendant unit.
20884 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20885 handle private with clauses properly, as well as to account for cases
20886 where the withed unit is a public descendant of a private ancestor
20887 (in which case the current unit must be a descendant of the private
20888 ancestor's parent). The spec comments were updated accordingly. Also,
20889 the old error message in this subprogram was replaced with error
20890 messages that mirror the errors tested and reported by
20891 Check_Private_Child_Unit.
20892 Parameter and variable names improved for readability.
20893 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20894 private as the precondition for calling
20895 Check_Private_Limited_Withed_Unit since that subprogram has been
20896 revised to test public units as well as private units.

20901 Javier Miranda <miranda@adacore.com>
20903 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20904 that Scope_Stack.First = 1.
20905 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20906 were not always properly handled previously.
20907 (Formal_Entity): Complete rewrite, to handle properly some complex case
20908 with multiple levels of parametrization by formal packages.
20909 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20910 to the corresponding derived type declaration for proper semantics.
20912 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20913 (Check_Component): Enforce restriction on components of
20914 unchecked_unions: a component in a variant cannot contain tasks or
20916 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20918 Add pragma Ada_2005 (synonym for Ada_05)
20919 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20920 were not always properly handled previously.
20921 Document that pragma Propagate_Exceptions has no effect
20922 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20923 (Set_Convention_From_Pragma): Check that if a convention is
20924 specified for a dispatching operation, then it must be
20925 consistent with the existing convention for the operation.
20926 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20927 longer required to specify an vtable-ptr component in the record. For
20928 compatibility reasons we leave the support for the previous definition.
20929 (Analyze_Pragma, case No_Return): Allow multiple arguments
20931 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20932 non-overrideen inherited operation with a controlling result as
20933 illegal only its implicit declaration comes from the derived type
20934 declaration of its result's type.
20935 (Check_Possible_Deferred_Completion): Relocate the object definition
20936 node of the subtype indication of a deferred constant completion rather
20937 than directly analyzing it. The analysis of the generated subtype will
20938 correctly decorate the GNAT tree.
20939 (Record_Type_Declaration): Check whether this is a declaration for a
20940 limited derived record before analyzing components.
20941 (Analyze_Component_Declaration): Diagnose record types not explicitly
20942 declared limited when a component has a limited type.
20943 (Build_Derived_Record_Type): Code reorganization to check if some of
20944 the inherited subprograms of a tagged type cover interface primitives.
20945 This check was missing in case of a full-type associated with a private
20947 (Constant_Redeclaration): Check that the subtypes of the partial and the
20948 full view of a constrained deferred constant statically match.
20949 (Mentions_T): A reference to the current type in an anonymous access
20950 component declaration must be an entity name.
20951 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20952 class_wide type to refer to full type, not to the incomplete one.
20953 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20954 available. Required to give support to the certified run-time.
20955 (Analyze_Component_Declaration): In case of anonymous access components
20956 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20957 (Process_Discriminants): For an access discriminant, use the
20958 discriminant specification as the associated_node_for_itype, to
20959 simplify accessibility checks.
20961 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20962 Javier Miranda <miranda@adacore.com>
20964 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20965 abstract interpretations on an operator, remove interpretations that
20966 yield Address or a type derived from it, if one of the operands is an
20968 (Try_Object_Operation.Try_Primitive_Operation,
20969 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20970 location when creating the new reference to a primitive or class-wide
20971 operation as a part of rewriting a subprogram call.
20972 (Try_Primitive_Operations): If context requires a function, collect all
20973 interpretations after the first match, because there may be primitive
20974 operations of the same type with the same profile and different return
20975 types. From code reading.
20976 (Try_Primitive_Operation): Use the node kind to choose the proper
20977 operation when a function and a procedure have the same parameter
20979 (Complete_Object_Operation): If formal is an access parameter and prefix
20980 is an object, rewrite as an Access reference, to match signature of
20981 primitive operation.
20982 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20983 by an expanded name with prefix Standard, when the operands are of an
20984 anonymous access type.
20985 (Remove_Abstract_Operations): If the operation is abstract because it is
20986 inherited by a user-defined type derived from Address, remove it as
20987 well from the set of candidate interpretations of an overloaded node.
20988 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20991 2006-02-13 Bob Duff <duff@adacore.com>
20993 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20994 redundant use clauses.
20995 In particular, if the scope of two use clauses overlaps, but one is not
20996 entirely included in the other, we should not warn. This can happen
20997 with nested packages.
20998 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20999 reported errors. The bug was reported when the compiler was built
21000 with assertions enabled.
21001 (Find_Type): If the node is a 'Class reference and the prefix is a
21002 synchronized type without a corresponding record, return the type
21005 2006-02-13 Javier Miranda <miranda@adacore.com>
21007 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21008 if this is the full-declaration associated with a private declaration
21009 that implement interfaces, then the private type declaration must be
21011 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21012 as aliased. The use of the 'access attribute is not available for such
21013 object (for this purpose the object should be explicitly marked as
21014 aliased, but being an anonymous type this is not possible).
21016 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21017 Robert Dewar <dewar@adacore.com>
21019 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21020 compilation unit is an elaboration scope.
21021 (Add_Task_Proc): Add '\' in 2-line warning message.
21022 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21024 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21025 Javier Miranda <miranda@adacore.com>
21027 * sem_type.adb (Write_Overloads): Improve display of candidate
21029 (Add_One_Interp): Do not add to the list of interpretations aliased
21030 entities corresponding with an abstract interface type that is an
21031 immediate ancestor of a tagged type; otherwise we have a dummy
21032 conflict between this entity and the aliased entity.
21033 (Disambiguate): The predefined equality on universal_access is not
21034 usable if there is a user-defined equality with the proper signature,
21035 declared in the same declarative part as the designated type.
21036 (Find_Unique_Type): The universal_access equality operator defined under
21037 AI-230 does not cover pool specific access types.
21038 (Covers): If one of the types is a generic actual subtype, check whether
21039 it matches the partial view of the other type.
21041 2006-02-13 Thomas Quinot <quinot@adacore.com>
21043 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21044 line. This is necessary to allow In_Extended_Main_Unit to provide
21045 correct results for itypes while writing out expanded source.
21046 (Close_File): No need to update the source_index_table here since it's
21047 now done for each line.
21049 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21050 Robert Dewar <dewar@adacore.com>
21052 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21053 preserve the source unit where the itype is declared, and prevent a
21055 (Note_Implicit_Run_Time_Call): New procedure
21056 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
21059 * sprint.ads: Document use of $ for implicit run time routine call

21063 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21066 2006-02-13 Bob Duff <duff@adacore.com>
21068 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21069 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21070 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21071 raise Constraint_Error.
21073 * s-vallli.adb (Scan_Long_Long_Integer): Call
21074 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21075 do not scan leading blanks and sign twice.
21076 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21077 raise Constraint_Error.
21079 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21080 Scan_Long_Long_Unsigned): Split out most of the processing from
21081 Scan_Long_Long_Unsigned out into
21082 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21083 This prevents scanning leading blanks and sign twice.
21084 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21087 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21088 out most of the processing from Scan_Unsigned out into
21089 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21090 This prevents scanning leading blanks and sign twice.
21092 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21093 use with Modular'Value attribute.
21094 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

21294 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21295 link to the version that does nothing. This way the task termination

21297 because of an unhandled exception.
21299 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21300 handler because of an unhandled exception.
21302 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

21315 instead for handling run-time termination in a more flexible way.
21316 (Adafinal_NT): This new procedure will take care of finalizing the
21317 global list for controlled objects if needed, but no tasking
21320 * s-tarest.adb (Task_Lock): Do not try to lock again the
21321 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21322 some run-time operations.
21323 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21324 until all nested locks have been released.
21325 (Task_Wrapper): Call the fall-back task termination handler. It

21333 moved to the Common_ATCB record.
21334 (Task_Lock): Global_Task_Lock_Nesting has been moved to the

21337 Common_ATCB record.
21339 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21340 Fall_Back_Handler, and Specific_Handler.

21345 Ada.Task_Termination, for avoiding circular dependencies.
21346 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21347 for storing task termination handlers. In addition,
21348 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21349 Common_ATCB because it is used by both the regular and the restricted
21351 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21352 Common_ATCB because it is used by both the regular and the restricted
21354 (Common_ATCB): Added a dynamic task analyzer field.

21362 using the soft links mechanism.
21363 (Task_Wrapper): added dynamic stack analysis.
21365 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21366 potentially blocking operations has been moved from
21367 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21368 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21369 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21370 this run-time check.
21372 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21373 of task termination procedure.

21416 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21417 to the specification because the frontend generates code that uses this
21419 (Set_Interface_Table): Add missing assertion.
21420 Update documentation describing the run-time structure.
21421 (Displace): New subprogram that displaces the pointer to the object
21422 to reference one of its secondary dispatch tables.
21423 (IW_Membership): Modified to use the new table of interfaces.
21424 (Inherit_TSD): Modified to use the new table of interfaces.
21425 (Register_Interface_Tag): Use the additional formal to fill the
21426 contents of the new table of interfaces.
21427 (Set_Interface_Table): New subprogram that stores in the TSD the

21442 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21443 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21444 record component containing the tag of the secondary dispatch table we
21445 have to use the Offset_To_Top run-time function to get this information;
21446 otherwise if the pointer to the base of the object has been displace
21447 we get a wrong value if we use the 'position attribute.
21449 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21450 all the calls to Expand_Interface_Thunk.

21454 ensure that the interfaces implemented by the ancestors are placed
21455 at the header of the generated list.
21456 (Expand_Interface_Conversion): Handle the case in which the displacement
21457 associated with the interface conversion is not statically known. In

21485 RE_TK_Tagged, RE_TK_Task.
21487 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21488 Init_Secondary_Tags_Internal to allow its use with interface types and
21489 also to generate the code for the new additional actual required
21490 by Set_Offset_To_Top.
21491 (Build_Init_Statements): In case of components associated with abstract
21492 interface types there is no need to generate a call to its IP.
21493 (Freeze_Record_Type): Generate Select Specific Data tables only for
21495 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21496 the bodies and specifications of the predefined primitive operations
21497 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21498 for concurrent types.

21503 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21504 properly protected objects and attach handler in the case of the
21505 restricted profile.

21518 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21519 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21520 about the use and expansion of SAVE_EXPRs in the various possible
21521 renaming handling cases.
21522 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21523 abusing DECL_FCONTEXT.

21620 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
21621 and the assignment to a class-wide object, before the assignment we
21622 generate a run-time check to ensure that the tag of the Target is
21623 covered by the tag of the source.

21688 copied component does not have a known static Esize, then reset
21689 the size and positional fields of the new component.
21690 (Analyze_Component_Declaration): A limited component is
21691 legal within a protected type that implements an interface.
21692 (Collect_Interfaces): Do not add to the list the interfaces that
21693 are implemented by the ancestors.
21694 (Derived_Type_Declaration): If the parent of the full-view is an
21695 interface perform a transformation of the tree to ensure that it has
21696 the same parent than the partial-view. This simplifies the job of the
21697 expander in order to generate the correct object layout, and it is
21698 needed because the list of interfaces of the full-view can be given in
21700 (Process_Full_View): The parent of the full-view does not need to be
21701 a descendant of the parent of the partial view if both parents are
21703 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21704 "limited" the parent must be a limited type.

21716 lists of interfaces constitute a set equality. If not, the first
21717 differing interface is returned.
21718 (Process_Full_View): Improve the check for the "no hidden interface"
21719 rule as defined by AI-396.

21778 available user-specified stream attributes on limited parameters to
21779 also test the type directly rather than only its underlying type (for
21780 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21781 attributes are visible at the point of the subprogram declaration.
21782 For Ada 2005, the error message is modified to indicate that the
21783 type's stream attributes must be visible (again, only for -gnat05).

21815 types use the corresponding record type. This was not needed before
21816 the implementation of Ada 2005 synchronized types because
21817 concurrent types were never tagged types in Ada 95.

21945 * socket.c: Add extern int h_errno for rtems since networking header
21946 files are not available at this point in a tool bootstrap. Newlib

22067 it did not matter because we always rewrote a/=b to not(a=b).
22068 (Expand_Allocator_Expression): For an allocator expression whose nominal
22069 subtype is an unconstrained packed type, convert the expression to its
22070 actual constrained subtype.
22071 Implement warning for <= or >= where < or > not possible
22072 Fix to Vax_Float tests (too early in many routines, causing premature
22073 Vax_Float expansions.

22080 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
22081 a string literal for precise control over warnings.
22082 Avoid raise of pragma in case of unrecognized pragma and just return

22087 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
22088 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter

22090 Include -gnatwx as part of -gnatg (warn on redundant parens)
22091 Allow optional = after -gnatm
22092 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22093 longer sets Elaboration_Checks.
22094 Code to set warning mode moved to Sem_Warn
22095 so that it can be shared by pragma processing.
22097 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if

22109 * exp_vfpt.adb: Handle /= case
22110 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22222 we are not defining the type.
22223 <E_Record_Type>: Likewise.
22224 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22225 to get advantage of the new maybe_stabilize_reference interface, to
22226 ensure that what we reference is indeed stabilized instead of relying
22227 on assumptions on what the stabilizer does.
22228 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22229 type imported through a limited_with clause, use its non-limited view.
22230 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22232 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22233 of #if sections + explicit comparisons of convention identifiers.

22239 that we are not defining.
22240 (elaborate_expression_1): Do not create constants when creating
22241 variables needed by the debug info: the dwarf2 writer considers that
22242 CONST_DECLs is used only to represent enumeration constants, and emits
22244 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22245 object with an address clause into an indirect reference, drop the
22246 initializing expression.

22258 subtype to build an actual type with bounds template.
22259 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22260 is provided by the front-end, use that subtype to compute the size of
22261 the deallocated object.

22268 maybe_stabilize, for common uses without restriction on lvalues and
22269 without need to check for the success indication.
22270 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22271 pass false instead of 0 as the FORCE argument which is a bool.
22272 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22273 attached to a renaming pointer has been properly stabilized, as no such
22274 object is attached otherwise.
22275 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22276 function uses the "target pointer" return mechanism.
22277 Reinstate conversion of the actual to the type of the formal
22278 parameter before any other specific treatment based on the passing
22279 mechanism. This turns out to be necessary in order for PLACEHOLDER
22280 substitution to work properly when the latter type is unconstrained.

22284 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

22286 and to let the caller know if the stabilization has succeeded.
22288 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22289 static output of record constructor if all the components are constant.
22290 (gnat_build_constructor): For a record type, sort the list of field
22291 initializers in increasing bit position order.
22292 Factor common code to build a storage type for an unconstrained object
22293 from a fat or thin pointer type and a constrained object type.
22294 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22295 types variants, and process special cases of VIEW_CONVERT expressions
22296 as their NOP_EXPR counterpart to ensure we get to the
22297 CORRESPONDING_VARs associated with CONST_DECls.
22298 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22299 on the right-hand side.

22306 extracting the object if converting to a type variant.
22307 (create_var_decl): When a variable has an initializer requiring code
22308 generation and we are at the top level, check for a potential violation
22309 of a No_Elaboration_Code restriction.
22310 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22311 SIZE and SIZE_UNIT which we need for later back-annotations.

22314 is an unchecked union.
22315 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22316 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22317 main variant, just replace the VIEW_CONVERT_EXPR.

22496 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22497 'Unrestricted_Access, if the designated type is an interface we
22498 add a type conversion to force the displacement of the pointer

22500 Use Universal_Real instead of Long_Long_Float when we need a high
22501 precision float type for the generated code (prevents gratuitous
22502 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22503 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22504 'Terminated for task interface class-wide objects. Generate a call to
22505 the predefined dispatching routine used to retrieve the _task_id from

22535 the return value into its actual subtype in order to help the backend
22536 to return the actual size instead of the maximum. This is another

22586 attribute of the N_Free_Statement.
22587 Generate itype for classwide designated object in both cases of
22588 user-specified storage pool: specific and class-wide, not only in the
22590 Raise CE when trying to set a not null access type object to null.

22867 In addition some minor reorganization of the code has been done to
22868 leave it more clear.
22869 (Analyze_Type_Declaration): If type has previous incomplete tagged
22870 partial view, inherit properly its primitive operations.

22884 be included in the interface list.
22885 (Access_Definition): If the designated type is an interface that may

22898 subprogram declaration.
22899 Change name Is_Package to Is_Package_Or_Generic_Package
22900 (Process_Formals): A non null qualifier on a non null named access

22915 Change name Is_Package to Is_Package_Or_Generic_Package
22916 (Preserve_Full_Attributes): For a synchronized type, the corresponding

22922 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22923 not try to rewrite a renamed stream attribute, because the operations
22924 on the type may not have been generated.
22925 Handle properly a renaming_as_body generated for a stream operation
22926 whose default is abstract because the object type itself is abstract.
22927 (Find_Type): If the type is incomplete and appears as the prefix of a
22928 'Class reference, it is tagged, and its list of primitive operations
22929 must be initialized properly.
22930 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22931 private declaration of a parent unit, prior to compiling the private
22932 part of a child unit, find on the scope stack the proper parent entity
22933 on which to link the use clause.

22956 (Valid_Conversion): If the operand has a single interpretation do not
22957 remove address operations.
22958 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22959 statement to inhibit warning.
22960 (Resolve_Unary_Op): Do not produce a warning when
22961 processing an expression of the form -(A mod B)
22962 Use Universal_Real instead of Long_Long_Float when we need a high

22965 (Resolve_Concatenation_Arg): Improve error message when argument is an
22966 ambiguous call to a function that returns an array.
22967 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

23942 Hristian Kirtchev <kirtchev@adacore.com>
23943 Javier Miranda <miranda@adacore.com>
23945 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23946 from object notation, the original node is unanalyzed and carries no
23947 semantic information, so that accessiblity checks must be performed on
23948 the type of the actual itself.
23949 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23950 compatibility with Build_Protected_Sub_Specification.
23951 (Check_Overriding_Inherited_Interfaces): Add suport to handle

23961 load comes from a Limited_With_Clause.
23963 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23964 whether a potential circularity is harmless, because it includes units
23965 loaded through a limited_with clause. Extends previous treatment which
23966 did not handle properly arbitrary combinations of limited and
23967 non-limited clauses.
23969 2005-09-01 Nicolas Setton <setton@adacore.com>
23971 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types

23984 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
23985 fully qualified name, to distinguish instances with the same local name.

24001 2005-09-01 Laurent Pautet <pautet@adacore.com>
24003 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
24004 position set is provided, we compute one in order to reduce the maximum
24005 length of the keys. This computation first selects a character
24006 position between 1 and the minimum length of the keys in order to
24007 avoid reducing one of the keys to an empty string.
24008 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24009 does not converge. The initialization procedure now comes with a
24010 maximum number of iterations such that when exceeded, an exception is
24011 raised in Compute. The user can initialize this ratio to another value
24013 Reformating and updated headers.

24017 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24018 that given an entity T creates and returns an Itype that duplicates the
24019 contents of T. The returned Itype has the null-exclusion
24020 attribute set to True, and its Etype attribute references T
24021 to keep the association between the two entities.
24022 Update copyright notice
24024 * sem_aggr.adb (Check_Can_Never_Be_Null,
24025 Aggregate_Constraint_Checks, Resolve_Aggregate,
24026 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.

24058 and N_Function_Specification.
24060 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
24061 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.

24117 Preset_Names for Name_Disp_Asynchronous_Select,
24118 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
24119 Name_Disp_Timed_Select.
24120 New pragma Debug_Policy
24122 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24124 Switch -gnata also sets Debug_Pragmas_Enabled
24126 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24127 handle an explicit -gnata when compiling predefined files.
24129 2005-09-01 Vincent Celier <celier@adacore.com>
24131 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24132 directories of projects that have no Ada sources.
24134 2005-09-01 Robert Dewar <dewar@adacore.com>
24136 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24137 (makes a difference for wide characters)
24139 * widechar.adb, widechar.ads:
24140 Add Wide_Char_Byte_Count feature to count chars vs bytes
24142 2005-09-01 Thomas Quinot <quinot@adacore.com>
24143 Ed Schonberg <schonberg@adacore.com>
24144 Robert Dewar <dewar@adacore.com>
24146 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24147 'Address attribute reference with an overloaded prefix, use the
24148 location of the prefix (not the location of the attribute reference) as
24149 the error location.
24150 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24151 a function renaming thereof, is a valid prefix for 'Size (where it is
24152 intepreted as a function call).
24153 (Statically_Denotes_Entity): New predicate to determine whether the
24154 prefix of an array attribute can be considered static.
24157 (Eval_Attr): Fix failure to evaluate Component_Size for
24158 unconstrained arrays (resulted in wrong value in packed case, since
24159 back end cannot handle this case)

24167 2005-09-01 Javier Miranda <miranda@adacore.com>
24168 Ed Schonberg <schonberg@adacore.com>
24170 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24171 become local to the whole package.
24172 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24173 the package was already analyzed the new algorithm "replaces" the
24174 real entities by the shadow ones. This is required to ensure that
24175 the order of these entities in the homonym chains does not change;
24176 otherwise we can have undefined references at linking time because
24177 in case of conflicts the external name of the entities will have
24178 a suffix that depends on the order of the entities in the chain.
24179 (Remove_Limited_With_Clause): Complementary code that completes the
24180 new algorithm and replaces the shadow entities by the real ones.
24181 (Install_Limited_Withed_Unit): When unchaining entities before the
24182 installation of the shadow entities, only regular entities of the
24183 public part must be taken into account. This is required to
24184 keep this routine in synch with the work done by Remove_Limited_
24186 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24187 even if unit is analyzed, because the analysis of the unit is
24188 idempotent in any case, and the limited view of the unit may have to
24189 be installed for proper visibility.
24190 (Expand_Limited_With_Clause): Even if the unit in the implicit
24191 with_clause has been analyzed already, a limited view of the package
24192 must be built for the current context, if it does not exist yet.
24194 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24195 Javier Miranda <miranda@adacore.com>
24196 Gary Dismukes <dismukes@adacore.com>
24198 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24199 defining entity for the instance body, make a new defining identifier
24200 rather than copying the entity of the spec, to prevent accidental
24201 sharing of the entity list.
24202 (Check_Private_View): When exchanging views of private types, build the
24203 list of exchanged views as a stack, to ensure that on exit the exchanges
24204 are undone in the proper order.
24205 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24206 Restore the compilation environment in case of instantiation_error.
24207 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24208 for an anonymous access result.
24209 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24210 (Formal_Entity): Handle properly the case of a formal package that
24211 denotes a generic package renaming.
24213 2005-09-01 Thomas Quinot <quinot@adacore.com>
24215 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24216 clause if the array aggregate is surrounded by parentheses.

24221 Javier Miranda <miranda@adacore.com>
24223 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24225 to check if a type is Constrained in cases related to code generation
24226 (rather than semantic checking) since otherwise we do not generate
24227 similar code for mutable private types depending if their
24228 discriminants are visible or not.
24229 (Check_Abstract_Overriding): Do not complain about failure to override
24230 the primitive operations used in dispatching selects since they will
24231 always be overriden at the freeze point of the type.
24232 (Access_Definition): Separate out handling for resetting the scope
24233 of an anonymous access function result type. Retrieve the scope
24234 of the associated function rather than using Current_Scope, which
24235 does not have a consistent value (depends on whether we're in the
24236 middle of analyzing formal parameters). Add ??? comment about
24237 finding a cleaner way to handle the special cases of scope setting.
24238 (Process_Incomplete_Dependents): A protected operation is never a
24239 dispatching operation (only its wrapper may be).
24240 (Build_Derived_Record_Type): In case of tagged private types that
24241 implement interfaces add derivation of predefined primitive
24243 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24244 by two parameters that are used in case of derivation from abstract
24245 interface types: No_Predefined_Prims is used to avoid the derivation
24246 of predefined primitives from the interface, and Predefined
24247 Prims_Only is used to complete the derivation predefined primitives
24248 in case of private tagged types implementing interfaces.
24249 Fix typo in comments
24250 (Find_Interface_In_Descendant): Protect the frontend against
24251 wrong code with large circularity chains.
24252 (Is_Private_Overriding): Add support for entities overriding interface
24253 subprograms. The test failed because Entities associated with overriden
24254 interface subprograms are always marked as hidden (and used to build
24255 the secondary dispatch table); in this case the overriden entity is
24256 available through the field abstract_interface_alias (cf. override_
24257 dispatching_operation)
24258 (Access_Definition): Set the scope of the type to Current_Scope for the
24259 case of a function with an anonymous access result type.
24260 (Access_Subprogram_Declaration): Handle creation of the type entity for
24261 an access-to-function type with an anonymous access result.
24262 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24263 in handling for N_Access_Function_Definition.
24264 (Analyze_Subtype_Declaration): Modify the text of error message.
24265 (Derived_Type_Declaration): Modify the text of error message.
24266 (Process_Subtype): Modify the text of error message plus cleanup
24267 of one redundant error message.
24268 (Analyze_Component_Declaration): Code cleanup.
24269 (Analyze_Object_Declaration): Code cleanup.
24270 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24271 attribute in case of access types. Code cleanup.
24272 (Array_Type_Declaration): Code cleanup.
24273 (Process_Discriminants): Create the new null-excluding itype
24274 if required. Code cleanup.
24275 (Process_Subtype): Create the new null-excluding itype if
24276 required. Code cleanup.
24277 (Build_Derived_Record_Type): Code cleanup to avoid calling
24278 twice the subprogram derive_subprograms in case of private
24279 types that implement interfaces. In this particular case the
24280 subprogram Complete_Subprograms_Derivation already does the
24281 job associated with the second call.
24283 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24284 conversion to the full view when generating an operation for a
24285 discriminant whose type may currently be private.
24287 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24288 Javier Miranda <miranda@adacore.com>
24290 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24291 V (Obj.F), the rewriting does not involve the indexed component, but
24292 only the selected component itself.
24293 Do not apply the transformation if the analyzed node is an actual of a
24294 call to another subprogram.
24295 (Complete_Object_Operation): Retain the entity of the
24296 dispatching operation in the selector of the rewritten node. The
24297 entity will be used in the expansion of dispatching selects.
24298 (Analyze_One_Call): Improve location of the error message associated
24300 (Analyze_Selected_Component): No need to resolve prefix when it is a
24301 function call, resolution is done when parent node is resolved, as
24303 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24304 when attempting to resolve a call transformed from its object notation.
24305 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24306 of the argument list for each interpretation of the operation.
24307 (Try_Object_Operation): The designated type of an access parameter may
24308 be an incomplete type obtained through a limited_with clause, in which
24309 case the primitive operations of the type are retrieved from its full
24311 (Analyze_Call): If this is an indirect call, and the return type of the
24312 access_to_subprogram is incomplete, use its full view if available.
24314 2005-09-01 Javier Miranda <miranda@adacore.com>
24315 Gary Dismukes <dismukes@adacore.com>
24317 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24318 access types the null-exclusion and access-to-constant attributes must
24320 (Analyze_Return_Statement): When the result type is an anonymous access
24321 type, apply a conversion of the return expression to the access type
24322 to ensure that appropriate accessibility checks are performed.
24323 (Analyze_Return_Type): For the case of an anonymous access result type,
24324 generate the Itype and set Is_Local_Anonymous_Access on the type.
24325 Add ??? placeholder for check to disallow returning a limited object
24326 in Ada 2005 unless it's an aggregate or a result of a function call.
24327 Change calls from Subtype_Mark to Result_Definition.
24328 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24329 Result_Definition in call to Make_Function_Specification.
24330 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24331 Set_Result_Definition.
24332 (Make_Inequality_Operator): Change formal Subtype_Mark to
24333 Result_Definition in call to Make_Function_Specification.
24334 (Process_Formals): Create the new null-excluding itype if required.
24335 (New_Overloaded_Entity): For an entity overriding an interface primitive
24336 check if the entity also covers other abstract subprograms in the same
24337 scope. This is required to handle the general case, that is, overriding
24338 other interface primitives and overriding abstract subprograms inherited
24339 from some abstract ancestor type.
24340 (New_Overloaded_Entity): For an overriding entity that comes from
24341 source, note the operation that it overrides.
24342 (Check_Conformance, Type_Conformant): Addition of one new formal
24343 to skip controlling formals in the analysis. This is used to
24344 handle overloading of abstract interfaces.
24345 (Base_Types_Match): Add missing case for types imported from
24346 limited-with clauses
24347 (New_Overloaded_Entity): Add barrier to protect the use of
24348 the "alias" attribute.
24350 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24352 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24353 verify that the procedure and the entry are mode conformant.
24354 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24355 as a different operator, which is often a cut-and-paste error.
24357 2005-09-01 Javier Miranda <miranda@adacore.com>
24358 Ed Schonberg <schonberg@adacore.com>
24360 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24361 used in controlling parameters exclude null because it is necessary to
24362 read the tag to dispatch, and null has no tag.
24363 (Override_Dispatching_Operation): If the previous operation is inherited
24364 from an interface, it becomes hidden and does not participate in later
24367 2005-09-01 Javier Miranda <miranda@adacore.com>
24368 Ed Schonberg <schonberg@adacore.com>
24369 Gary Dismukes <dismukes@adacore.com>
24371 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24372 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24373 the expander will generate the corresponding run-time check to evaluate
24375 (Resolve_Call): Check for legal type of procedure name or prefix that
24376 appears as a trigger in a triggering alternative.
24377 (Valid_Conversion): If expression is ambiguous and the context involves
24378 an extension of System, remove System.Address interpretations.
24379 (Resolve_Qualified_Expression): Reject the case of a specific-type
24380 qualification applied to a class-wide argument. Enhance comment
24381 to explain checking of Original_Node.
24382 (Resolve_Type_Conversion): The location of the error message was not
24383 general enough to handle the general case and hence it has been removed.
24384 In addition, this patch improves the text of the message.
24385 (Resolve_Type_Conversion): Add missing support for access to interface
24387 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24388 do not expand if the expression is the actual in a call, because proper
24389 expansion will take place when the call itself is expanded.
24390 (Resolve_Allocator): If the context is an unchecked conversion, the
24391 allocator inherits its storage pool, if any, from the target type of
24394 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24395 Javier Miranda <miranda@adacore.com>
24397 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24398 inherited interface operation that has an implementation, use the
24399 implementation to avoid spurious ambiguities.
24400 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24401 use the Corresponding_Record_Typ attribute to look for the interface
24402 because it is set by the expander (and hence it is not always
24403 available). For this reason we traverse the list of interfaces
24404 (available in the parent of the concurrent type).
24405 (Interface_Present_In_Ancestor): Handle entities from the limited view
24407 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24409 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24410 from the list of required components.
24411 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24412 primitive procedure of a limited interface with a controlling first
24414 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24416 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24417 capture if it is generated in the second operand of a short-circuit
24419 Do not capture values for variables with address clauses.
24420 (Is_Object_Reference): Treat a function call as an object reference only
24421 if its type is not Standard_Void_Type.
24423 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24425 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24426 to a variable that is statically known to be constant.
24428 2005-09-01 Geert Bosch <bosch@adacore.com>
24429 Robert Dewar <dewar@adacore.com>
24431 * ttypef.ads (VAXDF_Safe_First): Use correct value for constant.
24432 (VAXGF_Safe_First): Idem.

24440 Add documentation on environment variable syntax for Expand_Path
24442 * gnat_ugn.texi: Update documentation to include mention of -m switches
24443 Document new treatment of wide characters in max line length
24445 Remove -gnatL/-gnatZ switches, no longer used.
24446 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24449 * gnat_rm.texi: Add doc for two argument form of pragma
24450 Float_Representation.
24451 Add documentation for pragma No_Strict_Aliasing
24452 Add note that explicit component clause overrides pragma Pack.
24453 Add documentation of pragma Debug_Policy

24647 expression is a discriminant reference and its type is private, as can

24649 view of the type to resolve the case alternatives.

25208 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25209 longer protected objects. They have been replaced by lower-level
25210 suspension objects made up by a mutex and a condition variable (or
25211 their equivalent given a particular OS) plus some internal data to
25212 reflect the state of the suspension object.
25213 (Initialize, Finalize): Add this initialization procedure for
25214 Suspension_Object, which is a controlled type.
25215 (Finalize): Add the finalization procedure for Suspension_Object,
25216 which is a controlled type.
25218 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

25220 VxWorks specific version of this package. Target dependencies
25221 has been moved to System.Task_Primitives.Operations.
25223 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
25225 (InitializeCriticalSection, EnterCriticalSection,
25226 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25227 pCriticalSection by an anonymous access type so that we avoid problems
25228 of accessibility to local objects.

25234 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
25235 set the environment task mask here.
25236 (Current_State): Add this function that returns the state of the
25238 (Set_False): Add this procedure that sets the state of the suspension
25240 (Set_True): Add this procedure that sets the state of the suspension
25241 object to True, releasing the task that was suspended, if any.
25242 (Suspend_Until_True): Add this procedure that blocks the calling task
25243 until the state of the object is True. Program_Error is raised if
25244 another task is already waiting on that suspension object.
25245 (Initialize): Add this procedure for initializing the suspension
25246 object. It initializes the mutex and the condition variable which are
25247 used for synchronization and queuing, and it sets the internal state
25249 (Finalize): Add this procedure for finalizing the suspension object,
25250 destroying the mutex and the condition variable.

25255 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
25256 which provides a low-level abstraction (using operating system
25257 primitives) for Ada.Synchronous_Task_Control.
25258 This object is made up by a mutex (for ensuring mutual exclusion), a
25259 condition variable (for queuing threads until the condition is
25260 signaled), a Boolean (State) indicating whether the object is open,
25261 and a Boolean (Waiting) reflecting whether there is a task already
25262 suspended on this object.

25676 instantiations of Unchecked_Conversion, and allows them in bodies that
25677 are to be inlined by the front-end. When the body comes from an

25704 way as a normal component of an anonymous access type.
25705 (Resolve_Allocator): When an allocator's designated type is a class-wide
25706 type, check that the accessibility level of type given in the

25727 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25728 check on possible violation of restriction No_Direct_Boolean_Operators

26735 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

26738 error messages if expansion has been disabled due to previous
26739 (unrelated) errors).
26741 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26742 is disabled, the entity denoted by the argument is the access type

26754 denotes a type in the class.
26755 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26756 of Name_Generic_Dispatching_Constructor.
26758 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26759 05 unit for AI-260-02).

26773 the case of renaming of stream attributes when the renaming denotes a
26774 generic formal subprogram association for an abstract formal subprogram.
26775 Check that the attribute is a primitive stream attribute (and not
26776 a class-wide stream attribute) and then rewrite the attribute name
26777 as the name of the appropriate compiler-generated stream primitive.

26789 itype whose parent is controlled and not yet frozen, do not create a
26790 freeze node for the itype if expansion is disabled.
26792 2005-03-29 Vincent Celier <celier@adacore.com>
26794 * make.adb (Gnatmake): Don't fail if the main project file is declared
26795 as having no Ada sources. Do not display message "no sources to
26796 compile" in quiet output.

26816 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26817 rather than proceed ahead using a junk attribute name.
26819 2005-03-29 Vincent Celier <celier@adacore.com>
26821 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26823 * prj-part.adb (Parse_Single_Project): Set the location of a project
26824 on its defining identifier, rather than on the reserved word "project".
26826 * prj-proc.adb (Expression): Adapt to the fact that default of external
26827 references may be string expressions, not always literal strings.
26828 (Recursive_Process): Set Display_Name equal to Name
26829 when Location is No_Location, that is when there is no actual file.
26830 Get the Display_Name of the project from the source, when it is not a
26832 (Process): Use the Display_Name in error messages
26834 * prj-strt.adb (External_Reference): Allow default to be string
26835 expressions, not only literal strings.
26837 2005-03-29 Vincent Celier <celier@adacore.com>

27394 potentially required adjustments to the machine context for the GCC
27397 * raise.h (__gnat_adjust_context_for_raise): New prototype.
27399 * init.c (__gnat_adjust_context_for_raise) HPUX: Initial revision.
27400 Adjust PC by one in the provided machine context.

27444 Get_Line procedure.
27445 Avoid unnecessary use of Get/Set_Wide_String
27447 2005-03-15 Robert Dewar <dewar@adacore.com>
27450 * a-stunau.ads, a-stunau.adb:
27451 Change interface to allow efficient (and correct) implementation
27452 The previous changes to allow extra space in unbounded strings had
27453 left this interface a bit broken.
27455 * a-suteio.adb: Avoid unnecessary use of Get/Set_String

27497 Update documentation on Must_Be_Byte_Aligned for new spec
27499 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
27500 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
27501 uses of the Access_Disp_Table attribute to reference the first dispatch
27502 table associated with a tagged type. As
27503 part of the implementation of abstract interface types,
27504 Access_Disp_Table has been redefined to contain a list of dispatch
27505 tables (rather than a single dispatch table).
27506 Similarly, upgrade all the references to Tag_Component by the
27507 new attribute First_Tag_Component.
27508 (Find_Inherited_TSS): Moved to exp_tss.
27509 Clean up test in Expand_N_Object_Declaration for cases
27510 where we need to do a separate assignment of the initial value.

27512 declaration of a tagged type is an aggregate, no need to generate an
27513 additional tag assignment.
27514 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
27516 Bit packed array ops are only called if operands are known to be
27518 (Component_Equality): When returning an N_Raise_Program_Error statement,
27519 ensure that its Etype is set to Empty to avoid confusing GIGI (which
27520 expects that only expressions have a bona fide type).
27521 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
27522 determine the amount of data to be copied.
27524 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
27525 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):

27549 derived type definition nodes.
27550 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
27551 (Task_Present, Set_Task_Present): New subprogram.
27552 (Task_Body_Procedure): Removed.
27553 (Set_Task_Body_Procedure): Removed.
27554 These subprogram have been removed because the attribute
27555 Task_Body_Procedure has been moved to the corresponding task type
27556 or task subtype entity to leave a field free to store the list
27557 of interfaces implemented by a task (for AI-345)
27558 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27559 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27560 expression flag Do_Range_Check
27561 (Exception_Junk): Change to Flag7 to accomodate above change
27562 (Box_Present, Default_Name, Specification, Set_Box_Present,
27563 Set_Default_Name, Set_Specification): Expand the expression
27564 "X in N_Formal_Subprogram_Declaration" into the corresponding
27565 two comparisons. Required to use the csinfo tool.

27568 "with string" given.
27570 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
27573 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
27576 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27577 attribute Task_Body_Procedure rather than the old semantic field that
27578 was available in the task_type_declaration node.
27580 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27581 interface type definitions.
27582 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27585 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
27586 task type declaration.

27588 protected type declaration.
27590 2005-03-15 Doug Rupp <rupp@adacore.com>
27591 Vincent Celier <celier@adacore.com>
27593 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27594 (Gen_Output_File_C): Likewise.
27595 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
27597 2005-03-15 Thomas Quinot <quinot@adacore.com>
27599 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27600 is an N_Raise_Constraint_Error node, create a new copy of it without
27601 going through a call to Duplicate_Subexpr.
27603 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
27604 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27605 Nicolas Setton <setton@adacore.com>
27606 Ed Schonberg <schonberg@adacore.com>
27612 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27613 representation clause that prescribes a size not equal to the rounded
27614 size of their types.
27615 (gnat_to_gnu_entity, case E_Component): Always look at
27616 Original_Record_Component if Present and not the entity.
27617 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27618 of tagged extension types by not making field for components that are
27620 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27621 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27622 expression to the type of the object when the object is constant.
27623 Reverse defer_debug_incomplete_list before traversing it, so that trees
27624 are processed in the order at which they were added to the list. This
27625 order is important when using the stabs debug format.
27626 If we are deferring the output of debug information, also defer this
27627 output for a function return type.
27628 When adding fields to a record, prevent emitting debug information
27629 for incomplete records, emit the information only when the record is
27631 (components_to_record): New parameter defer_debug.
27632 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27633 (gnat_to_gnu_field_decl): New function.

27635 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27636 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27637 No longer update discriminants to not be a COMPONENT_REF.
27638 (copy_alias_set): Strip padding from input type; also handle
27639 unconstrained arrays properly.
27641 * gigi.h (write_record_type_debug_info): New function.
27642 Convert to use ANSI-style prototypes. Remove unused
27643 declarations for emit_stack_check, elab_all_gnat and

27645 (gnat_to_gnu_field_decl): New decl.
27647 * utils.c (write_record_type_debug_info): New function.

27652 (convert) <UNION_TYPE>: Accept slight type variations when
27653 converting to an unchecked union type.
27655 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27656 replace the N_Freeze_Entity with a null statement.
27658 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27659 within a constrained subcomponent of an enclosing record, place the
27660 freeze nodes in the scope stack entry for the enclosing record.

27662 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27663 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27664 within records; allow them to have freeze nodes if their base types
27667 * exp_util.adb (Remove_Side_Effects): Properly test for
27668 Expansion_Delayed and handle case when it's inside an
27669 N_Qualified_Expression.
27671 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27672 Comes_From_Generic, to recognize accurately that the parent type in a
27673 derived type declaration can be traced back to a formal type, because
27674 it is one or is derived from one, or because its completion is derived
27676 (Constrain_Component_Type): If component comes from source and has no
27677 explicit constraint, no need to constrain in in a subtype of the
27679 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27680 Minor change to propagate Is_Ada_2005 flag
27682 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27683 Expansion_Delayed is False.
27684 (assoc_to_constructor): Ignore fields that have a
27685 Corresponding_Discriminant.
27686 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27687 function returns "by target", dereference the target pointer using the
27688 type of the actual return value.
27689 <all>: Be prepared for a null gnu_result.
27690 (processed_inline_subprograms): Check flag_really_no_inline
27691 instead of flag_no_inline.

27701 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27702 Must_Be_Byte_Aligned for cases where we do not need to use a
27703 System.Pack_nn unit.
27705 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27707 Needed now that we do some processing for IN parameters as well. This
27708 may well fix some unrelated errors.
27709 (Expand_Call): Handle case of unaligned objects (in particular those
27710 that come from packed arrays).
27711 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27712 renamed entity is an inherited operation, re-expand the call using the
27713 original operation, which is the one to call.
27714 Detect attempt to inline parameterless recursive subprogram.
27715 (Represented_As_Scalar): Fix to work properly with private types
27716 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27717 accurate estimate. Yields True in far fewer cases than before,
27718 improving the quality of code that depends on this test.
27720 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27721 over both visible and private declarations to remove them from tree,
27722 and mark subprograms declared in package as eliminated, to prevent
27723 spurious use in subsequent compilation of generic units in the context.
27725 * exp_util.ads: Minor cleanup in variable names
27727 * sem_eval.ads, sem_eval.adb: Minor reformatting
27728 (Compile_Time_Known_Bounds): New function
27730 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27732 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27733 determining whether an unchecked conversion is needed for the argument
27734 of an initialization call.
27736 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27738 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27739 that appears in the instantiation rather than the internal subtype
27740 generated in the wrapper package, to avoid anomalies in gigi when the
27741 target is derived from a private type whose full view is an access type.
27743 2005-03-15 Robert Dewar <dewar@adacore.com>
27745 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27747 Add documentation to replace the use of this flag
27748 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27751 2005-03-15 Thomas Quinot <quinot@adacore.com>
27753 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27754 here from exp_attr so it can be shared between exp_attr and exp_dist.
27755 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27756 all TSS names, not a subset thereof, and the previous name introduced
27757 an unnecessarily confusion that a distinction might exist between
27758 "OK" TSS names and some "not OK" TSS names.
27760 2005-03-15 Doug Rupp <rupp@adacore.com>
27762 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27765 2005-03-15 Pascal Obry <obry@adacore.com>
27766 Eric Botcazou <ebotcazou@adacore.com>
27770 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27771 when IN_RTS. This is to work around a bootstrap path problem.
27773 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27774 table and pass it to __gnat_install_SEH_handler().
27775 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27777 * lang.opt: Fix specification of -fRTS=.
27779 2005-03-15 Doug Rupp <rupp@adacore.com>

27781 Vincent Celier <celier@adacore.com>
27782 Arnaud Charlet <charlet@adacore.com>
27785 This change works fine when gnatlib is built from the gcc directory,
27786 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27787 is not passed to ada/Makefile.in, so more work is needed by a
27788 Makefile/configure expert.
27790 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27791 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27792 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27794 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.

27799 2005-03-15 Robert Dewar <dewar@adacore.com>
27801 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27803 * impunit.adb: Add GNAT.UTF_32
27805 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27807 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27808 now uses GNAT.UTF_32).
27810 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27811 capabilities for categorizing characters using Unicode categories
27813 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27815 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27816 instantiation that has been rewritten as a package body, retrieve spec
27817 to generate proper name for implicit_with_clause.

27819 been rewritten as a package declaration during analysis.
27821 2005-03-15 Javier Miranda <miranda@adacore.com>
27822 Ed Schonberg <schonberg@adacore.com>
27824 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27825 parameter reported some error we immediately return. This improves the
27826 behaviour of the frontend in case of errors.
27827 (Install_Parent, Remove_Parent): Introduce new flag
27828 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27829 ancestor of a generic child unit, when the child is being instantiated.
27830 (Inline_Instance_Body): If we are compiling the private
27831 part or the body of a child unit, restore the proper visibility of the
27832 parents after compiling the instance body.
27834 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27835 Javier Miranda <miranda@adacore.com>
27838 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27839 of a private type, in which case it is underlying_type that denotes
27840 the proper task. Also modified to use the new entity attribute
27841 that is directly available in the task type and task subtype entities
27842 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27843 arrays when other dimensions than the first are constrained by
27844 discriminants of an enclosing record.
27845 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27846 a combination of indexed and selected components, find ultimate entity
27847 and generate the appropriate reference for it, to suppress spurious
27849 (Note_Possible_Modification): If an entity name has no entity, return.
27850 (Is_Variable): A function call never denotes a variable.
27851 (Requires_Transient_Scope): For record types, recurse only on
27852 components, not on internal subtypes that may have been generated for
27853 constrained components.

27857 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27858 Eliminated as candidates for resolution. Both efficient, and avoids
27859 anomalies with operators declared in deleted code.
27860 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27861 expansion is disabled (as when compiling a generic) to prevent spurious
27862 warnings on prefixes of selected components.
27864 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27866 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27867 attached to a list before checking whether it appears in the private
27868 declarations of the current package.
27869 (Make_Inequality_Operator): Insert declaration in proper declarative
27870 list rather than just setting the Parent field, so that
27871 Is_Private_Declaration can handle it properly.
27873 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27875 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27876 a renaming a body, check that the renamed subprogram in not intrinsic.
27877 (Find_Direct_Name): If several use_visible entities hide
27878 each other, and the context is a predefined file compiled through
27879 rtsfind, keep only the entity that comes from a predefined file.
27881 2005-03-15 Geert Bosch <bosch@adacore.com>
27883 * s-fatgen.adb (Valid): Extend special exceptions to account for long

28278 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28279 Remove ["0A"] from comment, since it can look like a line terminator.
28280 Currently we don't permit this, but this is under discussion by the
28281 ARG, and it is easy enough to use a different example.
28283 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28284 handling UTF-32 encoding for wide wide character.
28285 Implement new brackets coding ["hhhhhhhh"]
28286 Add UTF-8 encodings for full UTF-32 range
28288 * ttypes.ads: Add definition of Standard_Wide_Wide_Character_Size
28290 * types.h, types.ads, types.adb: Wide_Wide_Character now has full 31
28291 bit range Add full UTF-32 support.
28292 (RT_Exception_Code): Addition of CE_Null_Not_Allowed; used to
28293 notify that constraint error will be raised at run-time
28294 because a null value is assigned to a null-excluding object.
28295 Remove some obsolete declarations and make Char_Code
28298 * a-except.adb (Rcheck_30): New subprogram. Addition of the message
28299 corresponding to CE_Null_Not_Allowed, and adjust the output of all the
28300 Rcheck subprograms.
28302 * checks.adb (Check_Null_Not_Allowed): Replace the error message on
28303 wrong null-exclusion value by a warning message.
28304 (Enable_Range_Check): Do range check if the prefix is an
28305 explicit dereference whose designated object is an unconstrained array.
28306 Current algorithm for removing duplicate checks is over-eager in this
28309 * sem_ch5.adb (Analyze_Assignment): Replace the error messages on wrong
28310 null-exclusion value by a warning message
28312 * atree.h, atree.ads, atree.adb: Remove Char_Code field support
28313 completely. Add support for Uint2 field
28315 sem_ch2.adb, exp_ch11.adb, exp_dbug.adb,

28318 * exp_util.adb (Insert_Actions): Replace
28319 N_Formal_Subprogram_Declaration by
28320 N_Formal_{Abstract|Concrete}_Subprogram_Declaration.
28321 Char_Literal_Value field is now a Uint.
28323 * sinfo.ads, sinfo.adb (Corresponding_Formal_Spec): New function
28324 defined for subprogram renaming declarations. When set, the field
28325 indicates the defining entity of a corresponding formal subprogram
28326 when the renaming corresponds to a formal subprogram association in an
28328 (Set_Corresponding_Formal_Spec): New procedure to return
28329 Corresponding_Formal_Spec field.
28330 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration
28331 (which is now a subtype).
28332 Char_Literal_Value field is now a Uint
28334 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
28335 pointer to the base of the dispatch table.
28336 Minor changes to comments.
28337 (Controlling_Type): New function for determining the tagged type
28338 associated with a tagged primitive subprogram.
28339 (Expand_Dispatching_Call): Add support for a controlling actual that is
28340 directly a value of type Ada.Tag rather than a tagged object.
28342 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28343 describing the new layout.
28344 (Dispatch_Table): The expander computes the actual array size, allocates
28345 the Dispatch_Table record accordingly, and generates code that displaces
28346 the base of the record after the Typeinfo_Ptr component. The access to
28347 these components is done by means of local functions.
28348 (Offset_To_Top): New function.
28349 (Typeinfo_Ptr): New function.
28350 (Get_TSD): Modified to access the new position of the TSD.
28351 (Set_TSD): Modified to save the TSD in its new position.
28353 * par-ch12.adb (P_Formal_Subprogram_Declaration): Add parsing for the
28354 case of formal abstract subprograms. Add check and message for -gnat05.
28357 * sem_ch12.adb: Add with and use for Sem_Disp.

28361 N_Formal_Subtype_Declaration (which is now a subtype).
28362 (Analyze_Formal_Subprogram): Add handling for
28363 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28364 dispatching, setting the controlling status of the formal parameters
28365 and result, and issuing an error if there is no controlling type for
28366 the formal subprogram.
28367 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28368 which is an unclean use of that field, we set the new field
28369 Corresponding_Formal_Spec to make the formal subprogram available to
28370 processing in Analyze_Subprogram_Declaration.
28371 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28372 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
28373 Constrained, so that it is is does not statically match its anonymous
28376 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
28377 abstract formal subprograms in error check for functions returning
28378 abstract types. Set scope of new designator for
28379 a parameterless subprogram, so that it is available when checking the
28380 body for nested subprograms, before full analysis of said body.
28381 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28382 subprogram only if inner one comes from source.
28383 (Analyze_Function_Call): If the call is given in object notation, the
28384 analysis of the name rewrites the node and analyzes it with the proper
28385 argument list. After analyzing the name, if the call has been rewritten
28386 and the result type is set, no further analysis is needed.
28387 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28388 mark in function specification, in a context where the formals are
28389 visible and hide outer homographs.
28391 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28392 as the tagged type for the cases of abstract formal subprograms and
28393 renamings of those. Clean up spec comments.
28394 (Check_Dispatching_Context): Add error message to indicate "abstract
28395 procedure", covering the case of a call to a formal abstract procedure
28396 that has statically tagged operands.
28397 (Check_Dispatching_Call): Check for the case of an actual given by
28398 a tag-indeterminate function call whose type is an ancestor of the
28399 containing call's associated tagged type. This situation can occur
28400 for inherited primitives with function defaults. In this case we
28401 use the tagged type's tag directly as the controlling argument for
28403 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28405 * sprint.adb (Sprint_Node_Actual): Split
28406 N_Formal_Subprogram_Declaration into two alternatives for the new
28407 cases N_Formal_Abstract_Subprogram_Declaration and

28468 GNAT.OS_Lib.Set_Close_On_Exec.
28470 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
28471 the parent side as close-on-exec so that they are not inherited by the

28478 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28482 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28483 on the field if Pragma Component_Alignment (Storage_Unit).
28484 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28485 side-effects as if it were a constant; also make SAVE_EXPR to protect
28487 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
28489 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
28490 (components_to_record): Test it.

28503 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28505 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28506 component of an array of arrays in an assignment context, and the
28507 aggregate has component associations that require sliding on
28508 assignment, force reanalysis of the aggregate to generate a temporary
28509 before the assignment.
28510 (Must_Slide): Make global to the package, for use in Gen_Assign.
28512 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28514 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28515 unchecked union with no inferable discriminants, return a
28516 Raise_Program_Error node, rather than inserting it at the point the
28518 (Expand_Record_Equality, Component_Equality): Handle properly the case
28519 where some subcomponent is an unchecked union whose generated equality
28520 code raises program error.
28522 2005-02-09 Doug Rupp <rupp@adacore.com>
28524 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.

28528 Arnaud Charlet <charlet@adacore.com>
28530 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28531 address of the exception registration. The Win32 version of this
28532 routine calls __gnat_install_SEH_handler() to initialize the SEH
28533 (Structured Exception Handling) handler.
28534 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28535 SEH (Structured Exception Handling) now.
28536 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28537 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28538 preprocessor condition protecting the call to the extra eh setup
28539 subprogram, which is only available for the ppc target.
28540 (__gnat_clear_exception_count): replaced reference to
28541 variable taskIdCurrent by call to taskIdSelf(), cleaner.
28543 * seh_init.c: New file.
28545 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
28546 (GNATBIND_OBJS): Idem.
28548 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28549 routine takes a new parameter (a pointer to the exception registration
28550 for the SEH (Structured Exception Handling) support.
28552 * raise.h: (__gnat_install_SEH_handler): New prototype.
28553 Update copyright notice.
28555 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28556 record and initialize it by calling __gnat_install_SEH_handler.

28566 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
28567 [VMS]: Add translations for g-enblsp.adb.
28569 * s-asthan-vms.adb: Removed.
28570 * s-asthan-vms-alpha.adb: Added.
28572 2005-02-09 Pascal Obry <obry@adacore.com>

28581 -shared-libgcc is now used by default on some systems (e.g. linux with
28583 Remove references to Makefile.prolog/generic, no longer used.
28585 2005-02-09 Vincent Celier <celier@adacore.com>
28587 * prj-makr.adb (Process_Directory): Put file name in canonical case
28588 before matching against the patterns.
28589 If gnatname has been invoked as <prefix>-gnatname
28590 then invoke the compiler as <prefix>-gcc, not just "gcc".
28592 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28594 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28595 with expansion disabled. The actual subtype is needed among other
28596 places when the selected component appears in the context of a loop
28597 bound, and denotes a packed array.
28598 (Operator_Check): Always use the first subtype in the
28599 error message, to avoid the appearance of internal base types.
28600 (Transform_Object_Operation): Copy each actual in full
28601 to the parameter associations of the constructed call, rather than
28602 using the shallow copy mechanism of New_Copy_List. This ensures that
28603 the chaining of named associations is done properly.
28604 (Complete_Object_Operation): Rewrite node, rather than
28605 replacing it, so that we can trace back to the original selected
28608 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28609 and calls that use object notation, if the called function is not
28610 declared in a withed unit, place the elaboration constraint on the
28611 unit in the context that makes the function accessible.
28612 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28613 imposes an elaboration constraint between two packages.
28615 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28617 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28618 views of a private type after handling its private dependents, to
28619 maintain proper stack discipline between entry and exit from the
28622 2005-02-09 Cyrille Comar <comar@adacore.com>

28635 recursion warnings when compiled with -gnatdm.
28637 2005-02-09 Robert Dewar <dewar@adacore.com>
28639 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28640 Slight fix to documentation of -gnaty with no parameters
28642 * xr_tabls.ads: Add ??? comment for missing overall comment
28644 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28645 we now use by default.
28647 * xsnames.adb: Adjust end of file test to look for five space followed
28648 by '#' instead of six spaces. The format of xsnames.adb was modified
28649 in the last update.
28651 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28654 * clean.adb: Minor reformatting.
28656 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28657 gnatname.adb: Minor reformatting
28658 Add 2005 to copyright output when utility is run
28660 * csets.adb: Eliminate obsolete comment
28662 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28665 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28667 2005-02-09 Sergey Rybin <rybin@adacore.com>
28669 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28670 the difference between compact and incompact layout and add the record
28671 representation clause to the example illustrating different layouts.
28672 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28673 component clauses").
28675 2005-02-09 Florian Villoing <villoing@adacore.com>
28677 * gnat_ugn.texi: Fix typos.
28678 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28680 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28681 in the generated documentation.
28683 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28685 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
28687 Update linker wrapper when linking with non GNU C++.
28689 2005-02-09 Pascal Obry <obry@adacore.com>
28692 Document the procedure to debug the DllMain routine on Windows.
28693 Add note about -funwind-tables and mixed Ada and C/C++ programming in
28695 Document new BIND qualifer /RETURN_CODES=VMS.
28697 2005-02-09 Ben Brosgol <brosgol@adacore.com>
28699 * gnat_ugn.texi: Wordsmithing of "GNAT and Libraries" chapter
28700 Edited gnatmetric chapter

28715 * s-osinte-vxworks.ads (taskPriorityGet): Add this function (imported
28716 from the VxWorks kernel) that is needed for getting the active
28717 priority of the different tasks.
28719 * s-atacco.ads, s-atacco.adb (Nothing): Remove this dummy procedure.
28720 Use a pragma Elaborate_Body in the spec file instead.
28721 Noticed by code reading.
28723 2005-02-09 Thomas Quinot <quinot@adacore.com>
28725 * exp_util.ads: Minor correction in comment.
28727 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28729 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28730 since this procedure is now too complex to be worth inlining.
28732 2005-02-09 Richard Henderson <rth@redhat.com>
28734 * utils.c (gnat_define_builtin): Remove.
28735 (gnat_install_builtins): Use build_common_builtin_nodes.

29385 "no bitfield creation", to be used by make_aligning_type. Don't
29386 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
29387 fields claimed addressable still have to be bitfields. Use
29388 value_factor_p instead of a raw binop construction to check for the
29389 position's alignment.

29396 Ed Schonberg <schonberg@adacore.com>
29398 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29399 with an implicit dereference as its prefix, use
29400 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29402 prefix is generated, if appropriate.
29404 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29405 dereference is rewritten to an explicit one, generate a reference to
29406 the entity denoted by its prefix using the original prefix node, so

29408 access value, if appropriate.
29410 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29411 emitting 'assigned but never read' warning on a variable on the basis

29425 an external name, to be handled by the back end.
29427 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29428 subprogram which is Imported with convention Intrinsic if an
29429 External_Name argument is specified.
29430 (Process_Import_Or_Interface): Properly diagnose link name argument.
29431 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

29456 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29457 PCS-specific part of Add_Stub_Type.

29484 (Generate_Reference): Handle properly a reference to an entry formal,
29485 when an accept statement has a pragma Unreferenced for it.
29487 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29488 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29489 the body, to ensure that warnings are properly emitted for each accept
29490 statement of a given task entry.

29512 (Remove_Next_Debug): Same fix
29514 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do

29518 (Remove_Next): Same cleanup
29520 2004-12-07 Thomas Quinot <quinot@adacore.com>
29522 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29523 used to record an implicit dereference as a read operation on its
29524 prefix when operating under -gnatc. Necessary to avoid spurious
29525 'variable assigned but never read' warnings in that mode.
29526 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29527 is a non-overloaded implicit dereference, call the above subprogram to
29528 ensure proper recording of references.
29530 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29532 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

29580 2004-12-07 Vincent Celier <celier@adacore.com>
29582 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29583 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29584 and -eit to -ept. Added qualifier
29585 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29587 2004-11-27 Andreas Schwab <schwab@suse.de>
29589 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29591 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29593 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29594 internal implementation unit GNAT.Sockets.Thin,
29595 as their usage for sockets is non-portable (using the read and write
29596 functions from the system runtime library is fine on UNIX but won't
29597 work under Windows).

29653 new Others_Value and All_Others_Value objects.
29654 (struct attrib): Rename "arg" component as "args", since GCC expects a
29655 list of arguments in there.
29657 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29658 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29661 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29662 others_decl and all_others_decl instead of hardcoded dummy addresses
29663 to represent "others" and "all others" choices, which is cleaner and
29664 more flexible with respect to the possible eh pointer encoding policies.
29666 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29667 (process_attributes): Account for the naming change of the "args"
29668 attribute list entry component.
29670 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29671 cumulating attributes for different entities into a single list.
29672 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29673 attributes for the current entity and propagate first subtype
29674 attributes to other subtypes.
29675 <E_Procedure>: Attribute arguments are attr->args and not
29676 attr->arg any more.
29677 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29678 argument provided, as this is what GCC expects. Use NULL_TREE instead
29681 2004-11-18 Robert Dewar <dewar@adacore.com>
29683 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

29716 (First_RCI_Subprogram_Id): Document this constant.
29717 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29719 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29720 replaced with calls to Get_Library_Unit_Name_String. Previously there
29721 were several instances of the same code in different locations in the
29722 compiler; this checkin completes the replacement of all of these
29723 instances with calls to a common subprogram.
29724 Minor reformatting.

29757 that the pragmas are properly attached to the tree, and that no
29758 nodes are improperly shared.
29760 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29761 pragmas to Exp_Prag, which is more appropriate.
29762 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29763 check for duplicates Remove use of Is_Psected flag, no longer needed.
29764 Use new Make_String_Literal function with string.
29766 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29767 that are functions return universal values, that have to be converted
29768 to the context type.
29769 Use new Make_String_Literal function with string.
29770 (Get_Stream_Convert_Pragma): New function, replaces the use of
29771 Get_Rep_Pragma, which had to be kludged to work in this case.
29773 * freeze.adb: Use new Has_Rep_Pragma function
29775 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29776 function with string.
29777 Use new Has_Rep_Pragma function.
29779 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29782 2004-11-18 Robert Dewar <dewar@adacore.com>
29784 * errout.ads, errout.adb: (First_Sloc): New function
29786 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29787 check (-gnatyx) instead of being included as a redundant construct
29790 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29791 Style_Check_Order_Subprograms.
29793 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29794 stylesw.adb: Add Style_Check_Xtra_Parens
29796 * usage.adb: Add line for -gnatyx (check extra parens)
29798 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29800 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29801 Robert Dewar <dewar@adacore.com>
29803 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29804 discriminant of a constrained subtype, analyze the copy of the
29805 corresponding constraint, because in some cases it may be only
29806 partially analyzed.
29807 Removes long-lived ??? comments.
29809 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29810 handled controlled or secondary-stack expressions within the
29811 iteration_scheme of a loop.
29813 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29814 bounds that may contain functions calls, to prevent memory leaks when
29815 the bound contains a call to a function that uses the secondary stack.
29816 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29817 generate temporaries for loop bounds that might contain function calls
29818 that require secondary stack and/or finalization actions.
29820 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29821 selected component and the selector is overloadable (not just a
29822 function) treat as function call, Analyze_Call will disambiguate if
29824 (Analyze_Selected_Component): Do not generate an actual subtype for the
29825 selected component if expansion is disabled. The actual subtype is only
29826 needed for constraint checks.
29827 (Analyze_Allocator): If restriction No_Streams is set, then do
29828 not permit objects to be declared of a stream type, or of a
29829 composite type containing a stream.
29831 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29832 No_Streams no longer prohibits with'ing this package.
29834 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29835 discriminants, but the parent base has unknown discriminants, there is
29836 no discriminant constraint to inherit. Such a discrepancy can arise
29837 when the actual for a formal type with unknown discriminants is a
29838 similar private type whose full view has discriminants.
29839 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29840 do not permit objects to be declared of a stream type, or of a
29841 composite type containing a stream.
29843 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29845 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29846 protected operations.
29848 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29849 generated name, it complicates decoding in gdb and hinders debugging
29850 of protected operations.
29851 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29852 flag for the protected entry barrier function.
29853 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29854 flag for the protected entry function.
29856 2004-11-18 Nicolas Setton <setton@adacore.com>
29858 * expect.c: Define __unix__ when __APPLE__ is defined.
29860 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29861 Darwin-specific section.
29863 * lang-specs.h: Change the placement of the %1 marker.
29864 Works around the fact that gcc adds -fPIC by default under Darwin.
29866 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29868 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29869 type of the object with the packed array type, set the Analyzed flag
29870 on the object if it is an entity or simple indexed component, to avoid
29871 spurious type errors.
29873 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29875 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29876 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29877 separate line from the version message.
29879 2004-11-18 Ed Falis <falis@adacore.com>
29881 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29883 (init_float): Eliminate initialization of floating point status for
29884 AE653. The instructions have no effect for vThreads.
29886 2004-11-18 Vincent Celier <celier@adacore.com>
29888 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29889 gnatbind is invoked with -shared.
29891 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29893 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29894 for Detect_Blocking which is redundant with the check done within the
29895 procedure Protected_Single_Entry_Call.
29896 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29897 Detect_Blocking which is redundant with the check done within the
29898 procedure Protected_Single_Entry_Call.
29900 2004-11-18 Vincent Celier <celier@adacore.com>
29902 * makegpr.adb (Compile): Put the compiling switches (in package
29903 Compiler and on the command line) immediately after "-c", instead of
29904 at the end of the command line invocation of the compiler, when
29905 compiling a non-Ada file.
29906 (Build_Global_Archive): When there is no need to rebuild the archive,
29907 set Global_Archive_Exists, so that the archive is passed to the linker
29910 2004-11-18 Robert Dewar <dewar@adacore.com>
29911 Sergey Rybin <rybin@adacore.com>
29914 Remove extra paren check from list of checks for redundant constructs
29915 Add documentation of new -gnatyx style check (check extra parens)
29916 Remove paragraph about gnatelim debug options.
29918 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29919 objects rather than forbidding dependencies on the package Ada.Streams.
29921 * sinfo.ads: Add ??? note that we should document pragmas passed to
29924 * g-expect.ads: Fix a few typos in the comments.
29926 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29928 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29931 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29933 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29935 2004-11-07 Andreas Schwab <schwab@suse.de>
29937 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29939 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29942 * Makefile.in (darwin): Set soext to .dylib.
29944 2004-10-26 Vincent Celier <celier@gnat.com>
29945 Thomas Quinot <quinot@act-europe.fr>
29947 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29948 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29949 there is no use of GNAT.Sockets.Constants.
29950 Remove remaining pragma Import for C_Write
29951 Remove C_Read and C_Write from internal implementation unit
29952 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29953 the read and write functions from the system runtime library is fine
29954 on UNIX but won't work under Windows).
29956 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29957 (Check_Selector): Use C_Recv instead of C_Read.
29958 Selectors are the GNAT.Sockets abstraction to perform a select()
29959 call on a set of descriptors. To allow abortion of an ongoing
29960 select operation, some data is written to a dedicated socket that
29961 is always monitored.
29962 Under Windows, the write and read library functions cannot operate
29963 on sockets, so we need to use send and recv instead, which is portable
29964 across all supported platforms.
29966 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29967 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29968 (using the read and write functions from the system runtime library is
29969 fine on UNIX but won't work under Windows).
29971 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29973 * mlib-tgt-darwin.adb: New file.
29975 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29976 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29977 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29978 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29981 * Makefile.in: Add support for building shared libraries under Darwin.
29982 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29983 the low level EH init subprogram to be called from __gnat_initialize.
29985 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29986 indicates which options to pass to the archive indexer.
29988 * mlib-utl.adb: Add support for calling ranlib with additional
29989 options. This is needed for instance under Mac OS X.
29990 (Ranlib_Options): New global variable, used to store the potential
29991 options to pass to ranlib.
29992 (Ar): Use Ranlib_Options when spawning ranlib.
29993 (Initialize): Set the value of ranlib option.
29995 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29997 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29998 instead of 8K, to reflect the real potential needs for stack-checking
30001 2004-10-26 Pascal Obry <obry@gnat.com>
30003 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30005 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30006 Windows only the initial thread stack size can be set so it is good to
30007 start we a low stack size.
30008 The OS will adjust the size as needed.
30010 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30011 Nicolas Setton <setton@act-europe.fr>
30013 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30014 "__unix__" instead of "unix".
30015 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30016 sections were just mistakenly ignored. The former is
30017 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30018 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30019 of hpux. This prevents an unwanted definition of the symbol
30020 convert_addresses in adaint.o.
30022 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30024 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30025 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30027 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30029 * a-filico.ads, a-filico.adb: fix incorrect header.
30031 2004-10-26 Javier Miranda <miranda@gnat.com>
30033 * a-ststio.ads: Fix typo in identifier
30035 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30037 * sem_ch4.adb: Minor reformatting.
30039 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30041 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30042 enabled, check the result of unary and binary operations when the
30043 expression is the right-hand side of an assignment.
30045 2004-10-26 Vincent Celier <celier@gnat.com>
30047 * clean.adb (Delete): Do not output warnings when in quiet output and
30048 not in verbose mode.
30049 (Force_Deletions): New Boolean flag, defaulted to False
30050 (Delete): Only delete a file if it is writable, and when
30051 Force_Deletions is True.
30052 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30053 (Usage): Line for new switch -f
30054 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30057 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30059 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30060 JM type only if its size matches that of the wrapper. When a size is
30061 prescribed and the field is not aliased, remove the wrapper of a JM
30062 type only if the size is not greater than that of the packed array.
30063 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30066 2004-10-26 Geert Bosch <bosch@gnat.com>
30068 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30069 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30070 (Pred): Implement in terms of Succ.
30072 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30074 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30075 unchecked conversion is safe for in-place use if the expression of the
30076 conversion is safe.
30077 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30078 be expandable in place even if the aggregate does not come from source.
30079 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30080 designated object of an allocator in place, rather than building it
30081 first on the stack. The previous scheme forces a full copy of the array,
30082 and may be altogether unsusable if the size of the array is too large
30083 for stack allocation.
30085 2004-10-26 Robert Dewar <dewar@gnat.com>
30087 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30088 compares if the component is atomic.
30090 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30091 array assignment if the component type is atomic.
30093 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30094 Eric Botcazou <ebotcazou@act-europe.fr>
30096 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30097 is aliased and is a by_reference type, do not pass by copy.
30098 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30099 detect whether the call is in the right side of an assignment or
30100 the expression of an object declaration. Recurse on component
30101 association within aggregates.
30102 Call it in the condition that determines whether the temporary is
30103 necessary for correct stack-checking.
30105 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30107 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30108 RACW_Type, used in the PolyORB version.
30109 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30110 version and the GARLIC version.
30112 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30113 Rename RCI_Info to RCI_Locator for better consistency between the
30114 GARLIC and PolyORB versions of the distributed systems annex.
30115 (DSA_Implementation_Name): This enumeration lists the possible
30116 implementations of the Partition Communication Subsystem for the
30117 Distributed Systems Annex (DSA). The three available implementations
30118 are the dummy stub implementation (No_DSA), and two versions based on
30119 two different distribution runtime libraries: GARLIC and PolyORB. Both
30120 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30122 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30125 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30126 between the GARLIC and PolyORB versions of the distributed systems
30128 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30130 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30132 * gnat1drv.adb: Suppress calling the back end when
30133 Frontend_Layout_On_Target is true.
30135 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30137 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30138 Set_Read_Only): New subprograms.
30139 These new routines allow the user to set or unset the Owner execute
30140 and Owner write permission flags on a file.
30142 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30143 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30145 2004-10-26 Matthew Gingell <gingell@gnat.com>
30147 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30149 2004-10-26 Pascal Obry <obry@gnat.com>
30151 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30152 memory before the faulting page we properly test the process read
30153 access for this address using appropriate Win32 routine.
30154 (HPUX sections): guard with "__hpux__" instead of "hpux".
30156 2004-10-26 Robert Dewar <dewar@gnat.com>
30158 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30159 entry parameter if pragma Unreferenced set, since we do not properly
30160 handle the case of multiple parameters.
30162 2004-10-26 Vincent Celier <celier@gnat.com>
30164 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30165 (Ada_Objects_Path.Add): For a library project, add to the object path
30166 the library directory only if there is no object directory or if the
30167 library directory contains ALI files.
30168 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30170 2004-10-26 Vincent Celier <celier@gnat.com>
30172 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30173 extension of library projects.
30175 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30176 path defaults to ".:<prefix>/lib/gnat".
30177 (Parse): For an extending all project, allow direct import of a project
30178 that is virtually extended.
30180 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30181 the specified name is directly imported, return its ID. Otherwise, if
30182 an extension of this project is imported, return the ID of the
30185 2004-10-26 Robert Dewar <dewar@gnat.com>
30187 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30188 (Sub3): New procedure, used by Scaled_Divide
30189 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30190 correct more than one instance of failure to propagate carries
30192 (Double_Divide): Handle overflow case of largest negative number
30193 divided by minus one.
30195 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30196 the case of a quotient value out of range.
30199 2004-10-26 Robert Dewar <dewar@gnat.com>
30201 * s-bitops.adb (Bit_Eq): Remove redundant check.
30203 * s-bitops.ads: Minor comment updates
30204 Change some occurrences of Address to System.Address
30206 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30208 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30210 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30211 accessibility check to prefix that is a protected operation.
30213 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30215 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30216 empty, post message on stub.
30218 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30219 Javier Miranda <miranda@gnat.com>
30221 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30222 current instance appears within a unit that is directly in the context
30224 Used to determine whether the body of the instance should be analyzed
30225 immediately after its spec, to make its subprogram bodies available
30226 for front-end inlining.
30227 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30228 constraint is not allowed on the component type (AARM 12.5.3(3))
30230 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30232 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30233 'Storage_Pool): enhance, document & limit detection of non-sharable
30236 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30238 * s-pooglo.ads: Add more documentation now that this pool is properly
30241 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30243 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30244 or protected type with discriminants, do not constrain the
30245 corresponding record type if the subtype declaration has no
30246 discriminant constraints. This can be the case in source code, or in
30247 the subtype declaration created to rename an actual type within an
30250 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30252 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30253 different kind of stub (possibly wrong name for file), do not check
30255 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30256 includes call to some function that returns an unconstrained type, do
30259 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30261 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30262 appear in the code for the main unit. Dependencies among units in the
30263 context of the main unit are established when those other units are
30264 compiled. Otherwise spurious elaboration constraints can generate
30265 incorrect elaboration circularities.
30267 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30268 Ed Schonberg <schonberg@gnat.com>
30270 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30271 subprogram is called with a parameter that is not an object name. This
30272 situation arises for some cases of illegal code, which is diagnosed
30273 later, and in this case it is wrong to call Is_Aliased, as that might
30274 cause a compiler crash.
30275 (Explain_Limited_Type): Refine previous fix to include
30276 inherited components of derived types, to provide complete information.
30278 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30279 is the prival for a protected object.
30280 It is necessary to mark this entity as a variable, in addition to
30281 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30282 modified to avoid checking the Aliased flag on entities that are not
30283 objects. (Checking that flag for non-objects is erroneous and could
30284 lead to a compiler crash).
30286 2004-10-26 Robert Dewar <dewar@gnat.com>
30288 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30289 X_Frac = 0.5, then we know that the number X must be positive.
30290 (Succ): Remove the same redundant test, and also fix the primary test
30291 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30293 (Decompose): Add fuller comments to spec
30295 2004-10-26 Pascal Obry <obry@gnat.com>
30297 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30298 validity (process must have read access). Set to 0 in all other cases.
30299 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30300 violation on Win32.
30301 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30302 segmentation violation.
30304 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30306 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30307 whose type is a constructed subtype of an aliased object with an
30308 unconstrained nominal subtype, convert the actual to the constructed
30309 subtype before taking its address.
30311 2004-10-26 Vincent Celier <celier@gnat.com>
30313 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30314 (Is_Path_Name_Case_Sensitive): New function
30316 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30317 (Base_Name, Simple_Name, Current_Directory, Compose,
30318 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30321 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30322 Vasiliy Fofanov <fofanov@act-europe.fr>
30323 Vincent Celier <celier@gnat.com>
30325 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30326 "memory management issues" section and document some of the useful
30327 memory pools provided as part of the GNAT library.
30328 Remove "virtual" from declaration of A::method2 in
30329 the simple example of Ada/C++ mixed system.
30330 Library Projects may be virtually extended: their virtual extensions
30331 are not Library Projects.
30332 Added section on extending project hierarchies.
30334 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30336 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30338 (__gnat_portable_spawn): Remove const.
30340 * mingw32.h (MAXPATHLEN): Check for previous definition.
30342 2004-10-17 Matthias Klose <doko@debian.org>
30344 * gnatvsn.ads: Set gnat library version to 4.0.
30346 2004-10-05 Vincent Celier <celier@gnat.com>
30348 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30350 2004-10-04 Laurent Guerby <laurent@guerby.net>
30353 * Makefile.in: Define and use RANLIB_FLAGS.
30355 2004-10-04 Pascal Obry <obry@gnat.com>
30357 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30358 other x86 platforms).
30360 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30362 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30363 in general and triggers stack alignment adjustment for thread entry
30364 points on targets where this is necessary.
30366 2004-10-04 Bernard Banner <banner@gnat.com>
30369 * Makefile.in: Add section for powerpc linux
30370 Add variant i-vxwork-x86.ads
30372 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30374 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30376 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30377 table registration calls when need be. Ensures no reference to the crt
30378 ctors symbol are issued in the SJLJ case, which avoids possible
30379 undefined symbol errors in the case of modules to be statically linked
30382 2004-10-04 Javier Miranda <miranda@gnat.com>
30384 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30385 in-line the code corresponding to subprogram Analyze_Actuals. In
30386 addition, analyze the actuals only in case of subprogram call.
30388 2004-10-04 Ed Falis <falis@gnat.com>
30390 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30392 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30394 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30395 in the documentation.
30397 2004-10-04 Robert Dewar <dewar@gnat.com>
30399 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30401 (Analyze_Block_Statement): Add circuitry to detect following dead code
30402 (Check_Unreachable_Code): Handle case of block exit
30404 2004-10-04 Robert Dewar <dewar@gnat.com>
30406 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30407 (XMatchD): Avoid warning for Logic_Error call
30409 2004-10-04 Robert Dewar <dewar@gnat.com>
30411 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30412 consider expressions buried within a procedure actual to be an actual.
30413 This caused some blowups with uses of packed slices within a procedure
30416 2004-10-04 Robert Dewar <dewar@gnat.com>
30418 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30419 longer need to be initialized to zero.
30420 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30421 initialized to zero.
30423 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30424 considered valid, even if the representation is modular. That's correct
30425 now that we no longer initialize packed modular arrays to zero.
30427 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30428 suffixes. These are now documented as the only cases in which the
30429 debugger ignores outer records.
30430 Previously, the spec allowed arbitrary suffixes for this purpose.
30431 Change name of LJM to JM for packed array pad records
30432 Create separate section on packed array handling, and add a whole new
30433 set of comments to this section describing the situation with packed
30434 modular types and justification requirements depending on endianness.
30436 2004-10-04 Robert Dewar <dewar@gnat.com>
30438 * a-except.adb: Add a comment for last change
30440 * einfo.ads: Minor spelling correction in comment
30442 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30444 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30447 * sem_util.ads: Minor comment update
30449 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30451 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30452 Inline_Always when in Configurable_Run_Time mode.
30454 * sem_prag.adb (Process_Convention): If entity is an inherited
30455 subprogram, apply convention to parent subprogram if in same scope.
30456 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30457 when in Configurable_Run_Time mode.
30459 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30461 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30462 class_wide type after component list has been inherited.
30464 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30466 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30467 Denotes_Previous_Actual, to handle properly the case of a private
30468 actual that is also the component type of a subsequent array actual.
30469 The visibility status of the first actual is not affected when the
30470 second is installed.
30471 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30472 make fully recursive the treatment of formals of packages declared
30474 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30475 the above on exit from an instantiation.
30476 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30477 current instantiation which is now complete.
30478 (Analyze_Package_Instantiation): No instantiated body is needed if the
30479 main unit is generic. Efficient, and avoid anomalies when a instance
30480 appears in a package accessed through rtsfind.
30482 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30484 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30485 do not generate a declaration for a temporary if the call is part of a
30486 library-level instantiation.
30488 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30490 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30491 searching for a limited component to flag.
30493 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30494 expansion of Input, to account for the fact that the implicit call
30495 generated by the attribute reference must freeze the user-defined
30496 stream subprogram. This is only relevant to 'Input, because it can
30497 appear in an object declaration, prior to the body of the subprogram.
30499 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30500 expansion can proceed and further errors uncovered.
30501 (Minor clean up): Fix cases of using | instead of \ for continuation
30504 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30506 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30508 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30509 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30510 Use gcc_assert and gcc_unreachable.
30512 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30513 specified alignment before validating size.
30514 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30515 stripped-down declaration for the type of the inner field when making
30518 * utils.c (finish_record_type): Do not compute the size in units
30519 incrementally. Instead compute it once for the rep clause case.
30520 Use gcc_assert and gcc_unreachable.
30522 2004-10-04 Vincent Celier <celier@gnat.com>
30524 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30526 (Is_Valid_Path_Name): Take '/' as a directory separator.
30528 2004-10-04 Vincent Celier <celier@gnat.com>
30530 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30531 (Extended_Project) only if Extended_Project is defined, to avoid
30533 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30535 (Parse_Single_Project): Ditto.
30537 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30538 Add_To_Project_Path for virtual projects.
30540 2004-10-04 Vincent Celier <celier@gnat.com>
30542 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

30544 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30545 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30546 parameter Options_2.
30548 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30549 Build_Dynamic_Library with an empty Options_2.
30551 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30554 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30555 directory separator, if any.
30556 (Gprmake): Do not allow mains on the command line for library projects.
30557 Do not attempt to link when the project is a library project.
30558 (Library_Opts): New table to store Library_Options.
30559 (Build_Library): If Library_Options is specified, pass these options
30560 when building a shared library.
30562 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30564 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30565 the end of this procedure now that the unlock operation was inserted
30568 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30570 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30571 corresponding to the Preallocated_Stacks flags in System.
30572 (Get_Target_Parameters): Including the processing for
30573 Preallocated_Stacks.
30575 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
30576 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

30579 system-vxworks-sparcv9.ads, system-vxworks-xscale.ads,
30580 system-solaris-x86.ads, system-irix-o32.ads, system-irix-n32.ads,
30581 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
30582 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
30583 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
30584 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30585 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30586 used to signal whether the compiler creates the required stacks and
30587 descriptors for the different tasks (when True) or it is done by the
30588 underlying operating system at run time (when False).
30589 It is initially set to False in all targets.
30591 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30592 if it is supported by the target.
30593 (Make_Task_Create_Call): Pass the stack address if it has been
30594 previously created. Otherwise pass a Null_Address.
30596 * snames.adb: Add _stack.
30598 * snames.ads: Add Name_uStack. Required to allow the expander to
30599 statically allocated task stacks.
30601 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30602 Stack_Address argument.
30603 Check that its value is equal to Null_Address because this target does
30604 not support the static stack allocation.
30606 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30608 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30611 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30613 * exp_dist.adb: Split declaration of asynchronous flag out of
30614 Add_RACW_Read_Attribute.
30615 Minor reformatting for better alignment with PolyORB version.
30616 Store the entity for the asynchronous flag of an RACW, rather than the
30617 expression, in the asynchronous flags table. This will allow this flag
30618 to be used in other subprograms beside Add_RACW_Read_Attribute.
30620 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30622 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
30623 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
30624 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
30625 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
30626 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30627 sockets constant MSG_NOSIGNAL (Linux-specific).
30628 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30629 all Send operations.
30630 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30631 from trigerring SIGPIPE.
30632 Rename components to avoid clash with Ada 2005 possible reserved
30634 (Check_Selector): When the select system call returns with an error
30635 condition, propagate Socket_Error to the caller.
30637 2004-10-01 Jan Hubicka <jh@suse.cz>
30639 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
30641 2004-09-23 Robert Dewar <dewar@gnat.com>
30644 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
30645 instead do this at freeze time (we won't do it if there is an address
30647 Change "pragma inline" to "pragma Inline" in information and error
30649 Minor reformatting.
30651 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30652 right way of doing things after all.
30653 (Freeze_Entity): For object, set Is_Public for imported entities
30654 unless there is an address clause present.
30656 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30658 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30659 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30660 ensures proper handling of types with rep clauses, which might have
30661 their TYPE_SIZE set already.
30663 2004-09-21 Robert Dewar <dewar@gnat.com>
30665 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30666 packed array types in both little- and big-endian cases. This change
30667 ensures that we no longer count on the unused bits being initialized
30668 for such types (and in particular ensures that equality testing will
30669 only read the relevant bits).
30670 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30671 These changes mean that we no longer need to initialize small packed
30673 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30674 optimization to an LJM field as to its parent field.
30676 * ada-tree.h, trans.c, utils.c, utils2.c:
30677 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30679 2004-09-20 Jan Hubicka <jh@suse.cz>
30681 * utils.c (gnat_finalize): Remove.
30682 (end_subprog_body): Directly call cgraph_finalize_function;
30683 do not lower the nested functions.
30685 2004-09-20 Robert Dewar <dewar@gnat.com>
30688 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30689 if an address clause is present, since that means that the Import
30692 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30694 * 5tsystem.ads: Removed, no longer used.
30696 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30697 Zack Weinberg <zack@codesourcery.com>
30699 * ada-tree.def: Use tree_code_class enumeration constants
30700 instead of code letters.
30701 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
30702 Update for new tree-class enumeration constants.
30704 2004-09-17 Vincent Celier <celier@gnat.com>
30706 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private
30707 capabilities of the general project manager.
30709 2004-09-09 Vincent Celier <celier@gnat.com>
30711 * a-direct.ads: Add pragma Ada_05
30712 (Directory_Entry_Type): Give default value to component Kind to avoid
30713 not initialized warnings.
30715 * a-direct.adb (Current_Directory): Remove directory separator at the
30717 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
30718 an existing directory.
30719 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30720 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30721 Convert the result to File_Size.
30723 * prj.ads: (Project_Error): New exception
30725 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30726 Prj.Com, not from Osint.
30727 (Attrs, Package_Attributes): Tables moved to private part of spec
30728 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30730 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30731 Prj.Project_Error after call to Fail.
30732 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30733 Fail. Check that package name is not already in use.
30735 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30736 used by tools, not only by the project manager, and to indicate that
30737 exception Prj.Prj_Error may be raised in case of problem.
30738 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30740 (Attrs, Package_Attributes): Table instantiations moved from the body to
30741 the private part to be accessible from Prj.Attr.PM body.
30743 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30744 from new package Prj.Attr.PM.

30801 raise Program_Error if called from a protected operation.
30803 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30804 the protected action nesting level.
30805 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30806 protected action nesting level.
30807 (Unlock): When pragma Detect_Blocking is active decrease the protected
30808 action nesting level.
30810 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30811 Protected_Action_Nesting.
30813 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30814 Common_ATCB record. It contains the dynamic level of protected action
30815 nesting for each task. It is needed for checking whether potentially
30816 blocking operations are called from protected operations.
30817 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30818 Detect_Blocking is active or not in the partition.
30820 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

30852 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30853 insertion of the statement raising Program_Error. The run time
30854 contains the required machinery for handling that.
30856 * sem_util.ads: Change comment associated to procedure
30857 Check_Potentially_Blocking_Operation.
30858 This procedure does not insert a call for raising the exception because
30859 that is currently done by the run time.
30861 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30863 * init.c: Add the global variable __gl_detect_blocking that indicates
30864 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30865 making the pragma available at run time.
30866 (__gnat_set_globals): Pass and update the detect_blocking parameter.

30869 pragma Detect_Blocking is active.
30871 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30873 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30874 DB is found in the ali file. Any unit compiled with pragma
30875 Detect_Blocking active forces its effect in the whole partition.
30877 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30878 Detect_Blocking is active and delay is called from a protected
30881 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30882 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30883 Detect_Blocking is active (0 otherwise).
30884 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30885 as Detect_Blocking parameter if pragma Detect_Blocking is active (0

30890 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30891 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30894 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30895 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30896 Update API in placeholder implemetation of s-parint to reflect changes
30897 in distribution runtime library.
30899 * sem_ch3.adb (Expand_Derived_Record): Rename to
30900 Expand_Record_Extension.
30902 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30903 primitive operations of potentially distributed object types that have
30904 non-controlling anonymous access formals.
30906 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30908 New implementation of expansion for remote access-to-subprogram types,
30909 based on the RACW infrastructure.
30910 This version of sem_dist is compatible with PolyORB/DSA as well as
30913 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30914 Asynchrronous that applies to a remote access-to-subprogram type, mark
30915 the underlying RACW type as asynchronous.
30917 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30918 __gnat_using_gnu_linker to 1.
30920 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30921 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

30927 * exp_ch3.adb (Expand_Derived_Record): Rename to
30928 Expand_Record_Extension.
30929 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30930 a component declaration must remain attached at that point in the
30931 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30932 It is therefore necessary to take a copy of the expression when building
30933 the corresponding assignment statement in the init proc.
30934 As a side effect, in the case of a derived record type, we now see the
30935 original expression, without any rewriting that could have occurred
30936 during expansion of the ancestor type's init proc, and we do not need
30937 to go back to Original_Node.
30939 * exp_ch3.ads (Expand_Derived_Record): Rename to
30940 Expand_Record_Extension.

30947 subprogram. The proxy object is used as the designated object
30948 for RAS values on the same partition (unless All_Calls_Remote applies).
30949 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30950 System.Partition_Interface.Get_Unique_Remote_Pointer.
30951 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30952 Renamed from Add_RAS_*_Attribute.
30953 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
30955 New implementation of expansion for remote access-to-subprogram types,
30956 based on the RACW infrastructure.
30958 * exp_dist.ads (Copy_Specification): Update comment to note that this
30959 function can copy the specification from either a subprogram
30960 specification or an access-to-subprogram type definition.
30962 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30964 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30965 in an instance, between an explicit subprogram an one inherited from a
30966 type derived from an actual.
30968 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30969 add a polling call if the subprogram is to be inlined by the back-end,
30970 to avoid repeated calls with multiple inlinings.
30972 * checks.adb (Apply_Alignment_Check): If the expression in the address
30973 clause is a call whose name is not a static entity (e.g. a dispatching
30974 call), treat as dynamic.
30976 2004-09-09 Robert Dewar <dewar@gnat.com>
30978 * g-trasym.ads: Minor reformatting
30980 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

30989 2004-09-09 Pascal Obry <obry@gnat.com>
30991 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30992 enable map file generation. Add the right option to generate the map
30993 file if Map_File is set to True.
30995 * gnatdll.adb (Gen_Map_File): New variable.
30996 (Syntax): Add info about new -m (Map_File) option.

31024 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31025 of variable length temporaries for function return now that the
31026 back-end and gigi support it.

31077 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
31078 packed indexed component where array is an IN OUT formal. This
31079 generated garbage code previously.

31098 expander is not active (but check for unset reference to prefix of
31101 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
31102 pragma Debug as an if statement with a constant condition, for
31103 consistent treatment of entity references contained within the
31104 enclosed procedure call.
31106 2004-09-01 Vincent Celier <celier@gnat.com>
31108 * bindgen.adb: (Set_EA_Last): New procedure
31109 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure

31133 2004-09-01 Pascal Obry <obry@gnat.com>
31135 * gprcmd.adb (Extend): Do not output trailing directory separator. This
31136 is not needed and it confuses Windows GNU/make which does not report
31137 directory terminated by a slash as a directory.
31138 (gprcmd): Idem for "pwd" internal command.
31140 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
31141 target names rewrite to fix regressions with recent version of

31193 2004-08-16 Pascal Obry <obry@gnat.com>
31195 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
31196 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
31197 option and not mdll anymore. Update comment.
31199 2004-08-16 Pascal Obry <obry@gnat.com>
31201 * bld.adb (Put_Include_Project): Properly handle directory separators
31204 2004-08-16 Ed Schonberg <schonberg@gnat.com>

31217 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
31219 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
31220 for a global aliased object with a variable size and an unconstrained
31221 nominal subtype, pretend there is no initializer if the one we have is
31222 incomplete, and avoid referencing an inexistant component in there. The
31223 part we have will be rebuilt anyway and the reference may confuse
31224 further operations.
31226 2004-08-13 Thomas Quinot <quinot@act-europe.fr>
31228 * einfo.ads: Minor reformatting
31230 * lib-writ.adb (Output_Main_Program_Line): Do not set parameter

33206 * lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
33207 includes case of a variable referenced on the left hand side of an
33208 assignment, therefore remove redundant code. Variables and prefixes of

33210 hand side. Warnings are now properly emitted when variables or prefixes
33211 are assigned but not read.
33213 * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
33214 left hand side referenced variables. Private access types do not
33215 produce the warning "variable ... is assigned but never read".

33217 Aliased, renamed objects and access types do not produce the warning
33218 "variable ... is assigned but never read" since other entities may read
33219 the memory location.

33875 Merge from tree-ssa-20020619-branch.
33877 * config-lang.in (boot_language, build_by_default): Set

33914 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to

33916 constructs. The call was a no-op because Unit_Node has already been
33917 Analyzed, and the tree fragments for the distribution stubs are
33918 analyzed as they are inserted in Exp_Dist.
33919 Update comment regarding to distribution stubs to reflect that we
33920 do not generate stub in separate files anymore.

33938 has been rewritten as an explicit dereference, retrieve type of
33939 original node to check for possibly unconstrained record type.
33941 2004-05-10 Ed Schonberg <schonberg@gnat.com>
33943 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33944 overriding, use the operation of the parent unconditionally.
33946 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33947 operation when either operand is a literal, to avoid further
33950 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
33951 overridden by a previous explicit declaration, mark the previous entity
33954 * sem_disp.adb (Check_Dispatching_Operation): New predicate
33955 Is_Visibly_Controlled, to determine whether a declaration of a
33956 primitive control operation for a derived type overrides an inherited
33957 one. Add warning if the explicit declaration does not override.
33959 2004-05-10 Vincent Celier <celier@gnat.com>
33961 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
33962 some cases when the sources are no longer present.
33964 * make.adb (Collect_Arguments): Fail if an external source, not part
33965 of any project need to be compiled, when switch -x has not been
33968 * makeusg.adb: Document new switch -x
33970 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
33971 defaulted to False.

33975 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
33976 gnatmake switch -x.
33978 * gnat_ugn.texi: Document new gnatmake switch -x
33980 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
33982 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
33984 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
33985 (process_attributes): Likewise.
33987 2004-05-10 Joel Brobecker <brobecker@gnat.com>
33989 * s-inmaop.ads: Fix spelling mistake in one of the comments.
33991 2004-05-10 Robert Dewar <dewar@gnat.com>
33993 * gnat_ugn.texi: Document that for config pragma files, the maximum
33994 line length is always 32767.
33996 * gnat_rm.texi: For pragma Eliminate, note that concatenation of string
33997 literals is now allowed.
33999 * gnat-style.texi: Remove statement about splitting long lines before
34000 an operator rather than after, since we do not follow this rule at all.
34001 Clarify rule (really lack of rule) for spaces around exponentiation
34003 * sem_elim.adb: Allow concatenation of string literals as well as a
34004 single string literal for pragma arguments.
34006 * sem_prag.ads, sem_prag.adb: (Is_Config_Static_String): New function
34008 * a-textio.adb (Terminate_Line): Do not add line feed if nothing
34009 written for append case.
34011 * frontend.adb: Changes to avoid checking max line length in config
34014 * g-os_lib.ads: Minor reformatting
34016 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was
34017 wrong in any case. Instead use standard value. Noticed during code
34020 * opt.ads (Max_Line_Length): New field, used to implement removal of
34021 limitation on length of lines when scanning config pragma files.
34023 * osint.ads, prj-dect.adb, prj-strt.adb, prj-tree.adb,
34024 makeutl.ads, makeutl.adb: Minor reformatting
34026 * scn.adb: Do not check line length while scanning config pragma files

35215 as is done for non-private derived record types.
35217 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
35218 Ada 2005 AI-310: an abstract non-dispatching operation is not a
35219 candidate interpretation in an overloaded call.

35222 expression is Null and target type is not an access type (e.g. a

35233 complete assignment subtree which is now unnecessary, as the expansion
35234 of inlined call has been improved to preserve a consistent assignment
35235 tree. Note_Possible_Modification must be called only
35236 after checks have been applied, or else unnecessary checks will
35239 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35240 of explicit dereferences that do not Come_From_Source:

35242 pointer (an assignment to an implicit dereference must not be
35243 recorded as modifying the pointer);
35244 - do not rely on Original_Node being present (Analyze_Assignment
35245 calls Note_Possible_Modification on a copied tree).
35247 * sem_warn.adb (Check_References): When an unset reference to a pointer
35248 that is never assigned is encountered, prefer '<pointer> may be null'
35249 warning over '<pointer> is never assigned a value'.

35512 information for protected (wrapper) operation as well, to simplify gdb
35515 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

35558 a classwide type (for which Is_Object_Reference holds), but it can
35559 also be a value conversion for an access-to-classwide type. In the
35560 latter case, there is an implicit dereference, and the original node
35561 for the prefix does not verify Is_Object_Reference.

35647 gigi has enough information to construct the record, and there is no
35648 place in the tree for the declaration.
35650 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35651 serial number for the dummy body that is built for analysis, to avoid
35652 inconsistencies in the generation of internal names when compiling
35655 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35657 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35660 2004-03-22 GNAT Script <nobody@gnat.com>
35662 * Make-lang.in: Makefile automatically updated
35664 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35666 * decl.c (gnat_to_gnu_entity): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
35667 * trans.c (tree_transform, emit_index_check): Likewise.
35668 * utils.c (build_template): Likewise.
35669 (max_size, convert): Remove handling of WITH_RECORD_EXPR.

35689 Minor reformatting.
35691 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35693 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35694 as regular exception objects and not as mere integers representing the
35695 condition code. The latter approach required some dynamics to mask off
35696 severity bits, which did not fit well into the GCC table based model.
35697 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35698 exception data objects. We don't it and it would conflict with the other
35699 external symbol we have to generate for such exceptions.
35701 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35702 the special code for VMS exceptions, since these are now represented
35703 as regular exceptions objects.
35705 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35707 * decl.c (debug_no_type_hash): Remove.

35711 2004-03-19 Laurent Guerby <laurent@guerby.net>
35713 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35714 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35716 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35718 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35719 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.

35722 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35723 TYPE_VALUES, not TYPE_FIELDS.

35736 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35738 * adaint.c: Update comments.
35740 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35741 GNATLIB_SHARED for FreeBSD.
35743 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35745 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35746 When needed (stack checking) the stack size is retrieved
35747 from the VxWorks kernel.
35749 * Makefile.in: Flag -nostdinc is required when building the run time
35750 for avoiding looking for files in the base compiler.
35751 Add the VxWorks specific version of the package body for
35752 System.Stack_checking.Operations (5zstchop.adb).
35754 * Make-lang.in: Add the object file for
35755 System.Stack_Checking.Operations.

35763 checking from this package to package System.Stack_Checking.Operations.
35764 This way, stack checking operations are only linked in the final
35765 executable when using the -fstack-check flag.
35767 2004-03-18 Doug Rupp <rupp@gnat.com>
35769 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

35779 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35780 the procedures Add_To_Path_File.
35781 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35782 making sure that each directory is present only once and, for object
35783 dirs, when a directory already present is added, the duplicate is
35784 removed and the directory is always put as the last in the table.
35785 Write the path files at the end of these accumulations.
35787 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35788 Files_Htable for all sources.
35790 * prj-proc.adb (Process): Remove restrictions between not directly
35791 related extending projects.

35799 parameter Trusted_Mode.
35801 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35803 * scn.adb (Determine_License): Take into account a degenerated case
35804 when the source contains only comments.
35806 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35808 * sem_warn.adb (Check_References): For a warning on a selected
35809 component that does not come from source, locate an uninitialized
35810 component of the record type to produce a more precise error message.
35812 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35814 * 3zsoccon.ads: Fix multicast options.
35816 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35819 2004-03-15 Robert Dewar <dewar@gnat.com>
35821 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
35822 pragma used for a private type.
35824 * lib-xref.adb (Generate_Reference): Do not generate warning if
35825 reference is in a different unit from the pragma Unreferenced.
35827 * 5vtpopde.adb: Minor reformatting
35828 Fix casing of To_Task_ID
35830 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35831 flag if we have an unchecked conversion to an access type in the same
35834 2004-03-15 Geert Bosch <bosch@gnat.com>
35836 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35837 imaginary parts, use Double precision throughout.
35839 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35840 we want to be able to compile run-time with -gnata for testing, but
35841 this may also be instantiated in user code that is compiled with -gnata.
35843 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35845 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35846 codes. Having a separate type for this is useful to enforce consistency
35847 throughout the various run-time units.
35848 (Exception_Data): Use Exception_Code for Import_Code.
35850 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of

35853 with the severity bits masked off.
35854 (Register_VMS_Exception): Handle the additional exception data pointer

35858 component, now reflected by an exported accessor.
35859 (is_handled_by): New routine to compute whether the propagated
35860 occurrence matches some handler choice specification. Extracted out of
35861 get_action_description_for, and expanded to take care of the VMS
35863 (get_action_description_for): Use is_handled_by instead of an explicit
35864 complex condition to decide if the current choice at hand catches the
35865 propagated occurrence.
35867 * raise.h (Exception_Code): New type for C.
35869 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35870 System.Standard_Library.Exception_Code, to allow references from the
35871 pragma import/export expander.
35873 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35874 New accessors to allow easy access to GNAT exception data
35876 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35877 redundant Handled_By_Others component, helper for the personality
35878 routine which will now be able to call the appropriate exception data
35881 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35882 component of Standard_Exception_Type to be the closest possible to
35883 Exception_Code in System.Standard_Library, that we cannot get at this
35884 point. Expand a ??? comment to notify that this type node should
35885 probably be rewritten later on.
35887 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35888 registration call to include a pointer to the exception object in the
35891 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35892 instead of int and explicit bitmasks.
35894 2004-03-15 Vincent Celier <celier@gnat.com>
35896 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35897 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35899 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35900 longer needed now that it is in the spec of
35901 System.Tasking.Task_Attributes.
35903 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35905 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35907 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35909 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35910 taken care of in Scan_Make_Arg.
35911 (Scan_Make_Arg): Add the executable suffix only if the argument
35912 following -o, in canonical case, does not end with the executable
35913 suffix. When in verbose mode and executable file name does not end
35914 with executable suffix, output the executable name, in canonical case.
35916 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35917 to avoid warnings when instantiating Ada.Task_Attributes.
35920 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35921 in the correct order.
35923 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

35931 2004-03-15 Ed Schonberg <schonberg@gnat.com>
35933 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35934 tagged type is inherited, and the parent operation is not frozen yet,
35935 force generation of a freeze node for the inherited operation, so the
35936 corresponding dispatch entry is properly initialized.
35937 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35938 when looking for user-defined equality operation.
35940 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35941 boolean when locating primitive equality of tagged component.
35943 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

35945 a temporary before expanding assignment into a loop.
35947 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35948 priority in full, to ensure that any expanded subepxressions of it are
35949 elaborated in the scope of the init_proc.

35952 after object declaration, skipping over code that may have been
35953 generated for validity checks.
35955 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
35956 discriminants, ignore the known discriminants of its full view, if
35957 any, to check legality.
35959 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
35960 component if type has unknown discriminants.
35961 (Analyze_Private_Extension_Declaration): Discriminant constraint is
35962 null if type has unknown discriminants.
35964 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
35965 for end label when present.
35967 * s-fileio.adb (Open): When called with a C_Stream, use given name for
35968 temporary file, rather than an empty string.
35970 2004-03-15 Ed Falis <falis@gnat.com>
35972 * s-thread.adb: Removed, no longer used.

35994 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
35995 Insert_Dereference_Action when rewriting an implicit dereference into
35996 an explicit one, this will be taken care of during expansion of the
35997 explicit dereference.
35998 (Expand_N_Slice): Same. Always do the rewriting, even for the case
35999 of non-packed slices, since the dereference action generated by
36000 expansion of the explicit dereference is needed in any case.
36001 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36002 analyze and resolve the rewritten explicit dereference so it is seen
36004 (Insert_Dereference_Action): This procedure is now called only for the
36005 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36006 dereferences that do not come from source (including explicit
36007 dereferences resulting from rewriting implicit ones), but do not
36008 recursively insert a check for the dereference nodes contained within
36010 (Insert_Dereference_Action): Clarify and correct comment.

36887 checks for bitfield creation are triggered.
36888 (finish_record_type): During last pass over the fields, clear
36889 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

37276 be modified by the binder generated main program if the -D switch is
37279 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
37280 imported functions (since now we expect this to be done for imported
37283 * 5vtaprop.adb: Add several ??? for sections requiring more comments
37284 Minor reformatting throughout
37286 * 5zinit.adb: Minor reformatting

37290 doing reformatting)
37292 * sprint.adb: Minor updates to avoid -gnatwa warnings
37294 * s-secsta.ads, s-secsta.adb:
37295 (SS_Get_Max): New function to obtain high water mark for ss stack
37296 Default_Secondary_Stack is not a constant since it may be modified by
37297 the binder generated main program if the -D switch is used.
37299 * switch-b.adb: New -Dnnn switch for binder
37302 Make -gnatg imply all warnings currently in -gnatwa

37333 Acquire new SS indication of secondary stack use from ali files
37335 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
37336 (since now we expect this to be done for imported functions)
37338 * bindgen.adb: Generate call to modify default secondary stack size if
37341 * bindusg.adb: Add line for new -D switch
37343 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
37344 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
37345 Add circuitry for both records and arrays to avoid gigi
37346 processing if the type involved has non-bit-aligned components
37348 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37349 N_String_Literal node always references an E_String_Literal_Subtype
37350 entity. This may not be true in the future.
37351 (Possible_Bit_Aligned_Component): Move processing of
37352 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37354 * exp_ch6.adb (Expand_Thread_Body): Pick up
37355 Default_Secondary_Stack_Size as variable so that we get value modified
37356 by possible -Dnnn binder parameter.
37358 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37359 (Type_May_Have_Bit_Aligned_Components): New function.
37361 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

37394 * rtsfind.adb (Load_Fail): Give full error message in configurable
37395 run-time mode if all_errors mode is set. This was not done in the case
37396 of a file not found, which was an oversight.
37397 Note if secondary stack unit is used by compiler.
37399 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37400 ineffective elaborate all pragmas on non-visible packages (this
37401 happened when a renamed subprogram was called). Now the elaborate all
37402 always goes on the package containing the renaming rather than the one
37403 containing the renamed subprogram.
37405 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37406 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37409 has an Etype that references an E_String_Literal.
37410 (Eval_String_Literal): Avoid assumption that N_String_Literal node
37411 always references an E_String_Literal_Subtype entity. This may not
37412 be true in the future.
37414 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
37417 * sem_res.adb (Resolve): Specialize msg for function name used in proc
37420 2004-01-05 Ed Falis <falis@gnat.com>

37427 * bld.adb: Minor comment updates
37428 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
37431 * make.adb (Gnatmake): Special process for files to compile/check when
37432 -B is specified. Fail when there are only foreign mains in attribute
37433 Main of the project file and -B is not specified. Do not skip bind/link
37434 steps when -B is specified.
37436 * makeusg.adb: Document new switch -B

37465 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37467 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37468 all attributes, including read-only attribute.
37470 2004-01-05 Pascal Obry <obry@gnat.com>

37473 library naming scheme.
37475 * mlib-prj.adb (Build_Library): Generate different names for the static
37476 or dynamic version of the GNAT runtime. This is needed to support the
37477 new shared library naming scheme.

37479 based on the new naming scheme.
37481 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
37482 scheme for the shared runtime libraries.
37485 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
37487 (install-gnatlib): Do not create symlinks for shared libraries.
37488 (gnatlib-shared-default): Idem.
37489 (gnatlib-shared-dual-win32): New target. Not used for now as the
37490 auto-import feature does not support arrays/records.
37491 (gnatlib-shared-win32): Do not create copy for the shared libraries.
37492 (gnatlib-shared-vms): Fix shared runtime libraries names.
37494 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
37495 dependent runtime shared library name.
37497 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
37499 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
37502 2004-01-05 Ed Schonberg <schonberg@gnat.com>
37504 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37505 protected objects when allocator has a subtype indication, not a
37506 qualified expression. Note that qualified expressions may have to be
37507 checked when limited aggregates are implemented.
37509 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
37510 pure, emit warning.
37511 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
37512 subprogram is imported, remove warning.
37514 2004-01-05 Geert Bosch <bosch@gnat.com>
37516 * s-poosiz.adb: Update copyright notice.
37517 (Allocate): Use Task_Lock to protect against concurrent access.
37518 (Deallocate): Likewise.

37556 * cstand.adb (Create_Standard): Change the way how the declaration of
37557 the Duration type is created (making it the same way as it is for all
37558 the other standard types).
37560 2003-12-17 Robert Dewar <dewar@gnat.com>
37562 * s-crtl.ads: Fix header format
37563 Change Pure to Preelaborate

37568 the expression type only if it is declared in the current unit.
37570 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
37571 are universal and already analyzed, as can occur in constrained
37572 subcomponents that depend on discriminants, when one constraint is a
37575 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
37576 type Any_Fixed is legal as the argument of a conversion, if only one
37577 fixed-point type is in context.

37590 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
37591 (Gnatchop): Do not set failure status when reporting the number of
37594 2003-12-15 Doug Rupp <rupp@gnat.com>
37596 * s-ctrl.ads: New file.

37616 * Make-lang.in: Makefile automatically updated
37618 2003-12-11 Ed Falis <falis@gnat.com>
37620 * 5zinit.adb: Clean up.
37622 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37623 to __gnat_map_signal, imported from init.c to support
37624 signal -> exception mappings that depend on the vxWorks version.
37627 Created and exported __gnat_map_signal to support signal -> exception
37628 mapping that is dependent on the VxWorks version.

37656 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
37657 Minor reformatting throughout
37659 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37661 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37662 bounds of a loop, create a separate block in order to generate proper
37663 cleanup actions to prevent memory leaks.
37665 * sem_res.adb (Resolve_Call): After a call to
37666 Establish_Transient_Scope, the call may be rewritten and relocated, in
37667 which case no further processing is needed.
37669 * sem_util.adb: (Wrong_Type): Refine previous fix.
37670 Fixes ACATS regressions.
37673 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
37676 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
37678 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
37679 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
37682 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37685 2003-12-08 Robert Dewar <dewar@gnat.com>
37687 * 7sintman.adb: Minor reformatting
37689 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37690 standard linker options to get standard libraries linked. We now plan
37691 to provide dummy versions of these libraries to match the appropriate
37692 configurable run-time (e.g. if a library is not needed at all, provide
37693 a dummy empty library).
37695 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37696 options (-L parameters and standard libraries). What we plan to do is
37697 to provide dummy libraries where the libraries are not required.
37699 * gnatbind.adb: Minor comment improvement
37701 2003-12-08 Javier Miranda <miranda@gnat.com>
37703 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37704 aggregate in the parent. Otherwise constants with limited aggregates
37705 are not supported. Add new formal to pass the component type (Ctype).
37706 It is required to call the corresponding IP subprogram in case of
37707 default initialized components.
37708 (Gen_Assign): In case of default-initialized component, generate a
37709 call to the IP subprogram associated with the component.
37710 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37711 of aggregate with default initialized components.
37712 (Has_Default_Init_Comps): Improve implementation to recursively check
37713 all the present expressions.
37715 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37716 to indicate that the initialization call corresponds to a
37717 default-initialized component of an aggregate.
37718 In case of default initialized aggregate with tasks this parameter is
37719 used to generate a null string (this is just a workaround that must be
37720 improved later). In case of discriminants, this parameter is used to
37721 generate a selected component node that gives access to the discriminant
37724 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37725 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37726 allocated aggregates with default-initialized components.
37728 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37729 the box notation is used in positional aggregates.

37745 * prj-part.adb (With_Record): New component Node
37746 (Parse): New Boolean parameter Store_Comments, defaulted to False.
37747 Set the scanner to return ends of line and comments as tokens, if
37748 Store_Comments is True.
37749 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
37750 comments are associated with these nodes. Store the node IDs in the
37752 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
37754 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
37755 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
37756 current project. Call Tree.Restore afterwards. Set the various nodes
37757 for comment storage (Next_End, End_Of_Line, Previous_Line,
37760 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
37761 defaulted to False.
37763 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
37764 to False. When Truncated is True, truncate the string, never go to the
37766 (Write_End_Of_Line_Comment): New procedure
37767 (Print): Process comments for nodes N_With_Clause,

39510 a subunit is missing.
39511 (Instantiate_Subprogram_Body): If body of function is missing, set type
39512 of return expression explicitly in dummy body, to prevent cascaded
39513 errors when a subunit is missing.
39517 (Access_Subprogram_Declaration): Verify that return type is valid.
39521 (Check_Elab_Calls): Do not apply elaboration checks if the main unit is
39526 (Corresponding_Discriminant): If the scope of the discriminant is a
39527 private type without discriminant, use its full view.

41552 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41553 function approach did not work well because of a side effect (the
41554 function call could reallocate the table which was being indexed
41555 using its result). Fixes ada/4851.

41920 to Hbound, but no actual example of failure has been found.
41922 2001-12-17 Laurent Pautet <pautet@gnat.com>
41925 Fix comment of Shutdown_Socket and Close_Socket. These functions
41926 should not fail silently because if they are called twice, this
41927 probably means that there is a race condition in the user program.
41928 Anyway, this behaviour is consistent with the rest of this unit.
41929 When an error occurs, an exception is raised with the error message
41930 as exception message.

43264 instead of the previous simple checksum algorithm.
43265 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43266 (Set_Source_Table): idem.
43269 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43270 instead of simple checksum.
43271 (CRC_Match): new function.
43272 (CRC_Error): new constant.
43274 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43275 a CRC now and not a simple checksum. A CRC uses lower-case hex
43276 letters, fixes ambiguity in parsing.
43278 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43279 is what this variable will store.
43281 * bcheck.adb: Change reference to chechsum in comments by CRC.
43282 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43283 rename All_Checksum_Match to All_CRC_Match. Change due to API
43284 renaming since now GNAT does not use a simple checksum but a
43285 CRC using GNAT.CRC32.
43287 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43288 now and not anymore a simple checksum.

43325 Update comments for the CRC.
43327 * types.adb (Hex): Use lowercase for the letter part.
43329 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43330 for a word. This is currently used only for CRC. In previous version,
43331 the checksum was using a representation with all letter being
43332 upper-case. With the new implementation (using CRC) we do not remove
43333 the 32th bit of the CRC, so we can have an upper-case starting letter
43334 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43335 It is ambigous since the CRC was optional and could be followed by
43336 options like EB, EE. So now this routines uses lower-case letter for
43337 the hexadecimal representation. Strange enough only lower case letters
43338 where checked in Scan_ALI (even if this was not a possible case).
43340 * gnatvsn.ads (Library_Version): changed to 3.15a.
43342 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43345 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
