2173 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2174 Orig_Prev to Prev in the case where the actual is N_Function_Call or

4269 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4270 convention from its base type, do not set the type to that of integer,

4337 New local subprogram Is_Valid_Remote_Object_Type, replaces

4349 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4350 Is_Remote_Call_Interface to identify RACW types in a stable and
4351 consistent way. We used to rely in this predicate on the privateness of
4352 the designated type and its ancestors, but depending on the currently
4353 visible private parts, this caused false negatives. We now uniformly
4354 rely on checks made at the point where the RACW type is declared.

4368 Add missing escaping of all-caps word 'CPP' in error messages.
4369 (Build_Discriminated_Subtype): Do not inherit representation clauses
4370 from parent type if subtype already carries them, because they are
4371 inherited earlier during derivation and already include those that may
4372 come from a partial view.
4374 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):

4410 operation of an RACW stub type (these primitives are only executed
4411 through dispatching, never through static calls).
4412 (Collect_Interps): When only one interpretation has been found, set N's
4413 Entity and Etype to that interpretation, otherwise Entity and Etype may
4414 still refer to an interpretation that was ignored by Add_One_Interp,
4415 in which case would end up with being marked as not overloaded but with
4416 an Entity attribute not pointing to its (unique) correct interpretation.

8432 reference before the actual is resolved and expanded, to prevent
8433 spurious warnings on formals of enclosing protected operations.
8434 (Analyze_Overloaded_Selected_Component): If type of prefix if
8435 class-wide, use visible components of base type.

8541 clauses for inherited components of a type extension.
8542 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
8543 an overloadable item if it is a pragma that can apply to multiple
8544 overloadable entities (e.g. Inline) because a pragma cannot be on

8675 subprogram body that acts as its own spec may not have a non-private
8676 WITH clause on a private sibling.
8677 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8678 child unit is a renaming, create an implicit with_clause on that
8679 parent, and not on the unit it renames, to prevent visibility errors

8726 of Related_Interface to Related_Type.
8727 (Record_Type_Declaration): Minor reordering of calls to decorate the

8776 Gary Dismukes <dismukes@adacore.com>
8778 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
8779 requeue statement is dispatching. Do not emit an error when the name is
8780 not an entry and the context is a dispatching select. Add code to
8781 perform subtype conformance between the formals of the current entry
8782 and those of the target interface primitive.
8783 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8784 Timed_Entry_Call): Analyze the triggering statement as the first step of
8785 the processing. If this is a dispatching select, postpone the analysis
8786 of all select statements until the Expander transforms the select. This

8788 replicated some of the select statements. In case the Expander is
8789 disabled, perform regular analysis.
8790 (Check_Triggering_Statement): New routine.
8791 (Analyze_Requeue): Exclude any interpretations that are not entries when
8792 checking overloaded names in a requeue. Also test type conformance for

8798 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
8799 inherited operation is a defaulted tag-indeterminate call, and there is
8800 a statically tagged actual, use the static tag as a controlling actual
8801 for the defaulted actual.
8803 2007-12-13 Geert Bosch <bosch@adacore.com>
8805 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

8830 latest Ada 2005 rules about renaming and 'Access of
8831 discriminant-dependent components.

9401 * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
9402 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
9403 care of access to class-wide interface types plus removal of bizarre
9404 conversion of tagged object to access type (reported by Gary
9405 Dismukes). After this patch there is no need to perform any
9406 additional management on these nodes in Expand_Interface_Actuals.
9408 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9409 that handles use of 'Access and 'Unchecked_Access applied to
9410 actuals covering interface types. Such code is now
9411 centralized in Expand_N_Attribute_Reference.
9413 2007-10-15 Ed Schonberg <schonberg@adacore.com>
9415 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
9416 of tagged types whose ultimate ancestor is a CPP type.
9417 (Freeze_Array_Type): For a packed array type, generate an initialization
9418 procedure if the type is public, to handle properly a client that
9419 specifies Normalize_Scalars.
9421 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9423 * exp_ch9.adb (Actual_Index_Expression): When the expansion occurs
9424 inside a generic body, retrieve the full view of the entry family
9425 discrete subtype if available.

9452 for unsupported configurations; use it on VMS targets instead of the
9454 (EXTRA_LIBGNAT_SRCS,EXTRA_LIBGNAT_OBJS for VxWorks): Include
9455 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9456 used by VxWorks targets to have access to task-specific data and be
9457 able to extract the stack boundaries for stack checking.
9458 Use system-vms-ia64.ads on ivms.
9460 * Make-lang.in: Update dependencies.
9462 * sysdep.c (__gnat_get_stack_info): Move to a standalone file
9465 2007-10-15 Vincent Celier <celier@adacore.com>

9479 95 reserved word in its name.
9480 (Process_Project_Level_Array_Attributes): Process new attribute
9481 Runtime_Library_Dir.
9483 * prj-part.adb (Parse_Single_Project): Do not check the name of the
9484 config project against the user project names.
9486 * prj-proc.adb (Expression): In multi-language mode, indexes that do
9487 not include a dot are always case insensitive.
9488 (Process_Declarative_Items): Ditto
9489 (Process_Project_Tree_Phase_1): Set Success to False in case an error is
9492 * prj-util.adb (Value_Of (In_Array)): When Force_Lower_Case_Index is

9497 * rtsfind.adb: (Load_RTU): Turn off style checks for Load call
9499 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9501 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9502 association for an access component, add an association with null as
9503 the expression. Remove testing for array subtypes and the setting in
9504 that case of Ctyp to the array component type, which prevented proper
9505 inclusion of an association for null-initialized arrays. Collapse
9506 condition that tests for array subtypes into just a test of
9507 Is_Partially_Initialized_Type (which already covers arrays anyway).
9509 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9511 * sem_ch12.adb: Minor code reformatting.
9512 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to
9513 find the parent package which may have been hidden by local
9516 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9518 * sem_ch3.adb (Build_Derived_Concurrent_Type): Set the Is_Constrained
9519 flag of derived concurrent types, taking into account the flag setting
9520 on the parent subtype and any new set of discriminants.
9522 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9524 * sem_ch4.adb: Minor code and comment reformatting.
9525 (Analyze_Allocator): When the designated type of an unconstrained
9526 allocator is a record with unknown discriminants or an array with
9527 unknown range bounds, emit a detailed error message depending on the
9528 compilation mode and whether the designated type is limited.
9530 2007-10-15 Tristan Gingold <gingold@adacore.com>
9532 * system-vms-ia64.ads: New file.
9534 * system-vms_64.ads: Minor comment fix.

9538 * sem_ch6.adb (Find_Corresponding_Spec): If the previous entity is a
9539 body generated for a function with a controlling result that is a null
9540 extension, discard the generated body in favor of the current explicit
9543 2007-10-15 Ed Schonberg <schonberg@adacore.com>
9545 * sem_disp.adb (Find_Controlling_Arg): Examine the call node before
9546 examining its original form, to handle properly operator calls that
9547 have been rewritten.

9576 * xr_tabls.adb (Add_Reference): Add support for the new 'R' reference
9577 type, for dispatching calls.
9579 2007-10-15 Vincent Celier <celier@adacore.com>
9580 Robert Dewar <dewar@adacore.com>
9582 * gnat_ugn.texi: Add documentation for switches --version and --help
9583 for the GNAT tools gnatbind, gnatlink, gnatmake, gnatchop, gnatname,
9584 gnatxref, gnatfind, gnatls, and gnatclean.

9599 * g-soccon-vms.ads: Fix value of MSG_WAITALL.
9602 Update documentation to note that OpenVMS 8.3 or later must be used
9603 to generate g-soccon-vms.ads.
9605 * atree.adb: Add ??? comment
9607 * exp_util.adb: Minor reformatting.
9608 Add ??? comment in Kill_Dead_Code.
9610 2007-10-15 Robert Dewar <dewar@adacore.com>

9627 * g-comlin.adb: (Start): Fix handling of empty command line.
9629 * gnatcmd.adb (GNATCmd): Do not put the -rules in the -cargs section,
9630 even when -rules follows the -cargs section.

9651 2007-09-27 Eric Botcazou <ebotcazou@adacore.com>
9653 Mapped location support
9654 * back_end.adb (Call_Back_End): Pass information about source
9655 files instead of units to gigi.
9656 * gigi.h (struct File_Info_Type): New.
9657 (gigi): Rename and change type of number_units parameter, change
9658 type of file_info_ptr parameter.
9659 * trans.c (number_files): New global variable.
9660 (gigi): Rename and change type of number_units parameter, change
9661 type of file_info_ptr parameter.
9662 If mapped location support is enabled, create the isomorphic mapping
9663 between source files and line maps.
9664 (Sloc_to_locus): If mapped location support is enabled, translate
9665 source location into mapped location.
9666 (annotate_with_node): Rename into set_expr_location_from_node.
9667 Call set_expr_location instead of annotate_with_locus.
9668 (Pragma_to_gnu): Adjust for above change.

9690 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9692 * a-calend-vms.adb, a-calend.adb:
9693 Add a section on leap seconds control along with two entities used to
9694 enable and disable leap seconds support. The array Leap_Second_Times is
9695 now constant and contains hard time values pre-generated. Remove
9696 all elaboration code used to populate the table of leap seconds.
9699 Add entity Leap_Seconds_Support to the list of global run-time variables
9700 along with a comment on its usage and values.
9701 (Gen_Adainit_Ada): Add code to generate the declaration and import of
9702 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
9703 or one (enabled) depending on the presence of binder switch "-y".
9704 (Gen_Adainit_C): Add code to generate the declaration of external int
9705 __gl_leap_seconds_support. Set is value to zero (disabled) or one
9706 (enabled) depending on the presence of binder switch "-y".

9715 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
9716 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
9718 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
9720 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
9721 function which can be called by the debugger to interrupt the tasks of
9722 an Ada application asynchronously, as needed on VxWorks.
9723 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
9725 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
9726 renamed from Stop_All_Tasks. Update comments.
9727 (Stop_All_tasks): New function declaration.
9729 2007-09-26 Olivier Hainque <hainque@adacore.com>
9731 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
9732 #include <utime.h> and #define GCC_RESOURCE_H before
9733 #include <sys/wait.h>.
9734 Add more protections in __gnat_translate_vms.
9736 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
9737 #include <sys/wait.h>.
9739 2007-09-26 Thomas Quinot <quinot@adacore.com>
9740 Sergey Rybin <rybin@adacore.com>
9742 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
9744 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9747 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9749 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9752 * sem_dist.ads: Minor comment fix
9754 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9756 2007-09-26 Javier Miranda <miranda@adacore.com>
9757 Eric Botcazou <ebotcazou@adacore.com>
9760 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9761 indirection added to the HT_Link component of the TSD. This is required
9762 to statically allocate the TSD.
9765 Minor reordering of the declarations in the private part. Required to
9766 add a level of indirection to the contents of the TSD component HT_Link.
9767 This is required to statically allocate the TSD.
9769 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9770 Is_Statically_Allocated set from constant objects.
9771 Do not make exported constants created by the compiler volatile.
9772 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9775 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9776 before returning them.
9778 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9779 public part of the package.
9780 (Make_DT): Move HT_Link component out of the TSD record. For this
9781 purpose Make_DT now declares a separate object that stores the
9782 HT_Link value, and initializes the TSD component with the address
9783 of this new object. The addition of this level of indirection is
9784 required to statically allocate the TSD because the TSD cannot
9785 have variable components.
9786 (Expand_Interface_Conversion): Improve the expanded code.
9787 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9789 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9790 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9791 if we are building static dispatch tables then we must not generate
9792 extra code to register the primitive because the dispatch table will
9793 be built at the end of the library package; otherwise we notify that
9794 we cannot build the static dispatch table.
9796 2007-09-26 Robert Dewar <dewar@adacore.com>
9798 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9813 for thunks associated with interface types.
9815 * einfo.ads: Improve documentatation of Is_Internal
9816 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9817 associated with interface types.
9818 Extensive comment fixes regarding flags that appear in all entities. The
9819 documentation is now consistent for all such flags (there were a number
9820 of errors in the documentation in this regard).
9822 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9824 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9825 of these procedures are passed a function call that already has
9826 build-in-place actuals (testing new flag
9827 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9828 the case where processing continues.
9829 (Expand_Call): If the call is generated from a thunk body then we
9830 propagate the extra actuals associated with the accessibility
9831 level of the access type actuals.
9833 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9834 of each extra formal of a protected operation to reference the
9835 corresponding extra formal of the subprogram denoted by the
9836 operation's Protected_Body_Subprogram.
9838 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9839 N_Function_Call nodes.
9841 2007-09-26 Robert Dewar <dewar@adacore.com>
9843 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9845 * debug.adb: Add d.s flag.
9847 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9849 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9850 debug variable so that it won't be initialized when pragma
9851 Initialize_Scalars is in effect.
9853 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9855 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9856 initialization of a full view. This is moved to
9857 Analyze_Package_Specification.
9859 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9860 preelaborable initialization of a full view in entity loop.
9861 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9862 its child units are use-visible only if they are visible child units.
9864 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9865 whether an expression can be used within a type declaration that
9866 requires preelaborable init.
9867 (Check_Components): Replace inline code that does partial checking for
9868 preelaborable default expressions with call to
9869 Is_Preelaborable_Expression.
9870 (Has_Preelaborable_Initialization): In the case of a generic actual
9871 subtype, (that is, Is_Generic_Actual is True), return the result of
9872 applying Has_Preelaborable_Initialization to the generic actual's base
9875 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9877 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9878 call to Jan_1_Day _Of_Week to optimize its performance.
9879 (Is_Leap): Move the routine to the scope of Week_In_Year.
9880 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9881 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9882 avoids calling Time_Of and Split, thus making it more efficent.
9883 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9885 * g-calend.ads (Week_In_Year): Change comment to reflect new
9888 2007-09-26 Emmanuel Briot <briot@adacore.com>
9890 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9891 Command_Line): New types
9892 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9893 support for defining how switches can be grouped on a command line (as
9894 is the case for -gnatw... for GNAT), and how simple switches can be
9895 used as aliases for more complex switches (-gnatwa is same as
9897 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9898 (Start, Current_*): New subprograms
9899 Added support for parsing an array of strings in addition to the real
9901 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9902 be moved from the body to the private part of the spec.
9903 (*): All subprograms now have an extra parameter with default value to
9904 specify which parser should be used. For backward compatibility, it
9905 defaults to parsing the command line of the application. They were also
9906 modified to properly handle cases where each of the argument does not
9907 start at index 1 (which is always true for Ada.Command_Line, but not
9908 when processing any Argument_List).
9909 (Free): New subprogram
9910 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9911 Argument): New subprograms
9912 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9913 special characters like ':', '=',... are now handled in a single place,
9914 which makes the code more extensible eventually.
9915 (Getopt, Full_Switch): When the switch was returned as part of the
9916 special character '*', make sure it is prepended by the switch character
9917 ('-' in general), so that the application knows whether "foo" or "-foo"
9918 was specified on the command line.

10311 Thomas Quinot <quinot@adacore.com>
10313 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
10314 create an abstract subprogram in the case of 'Input. For 'Output we now
10315 create a real spec/body when the type is abstract, since it can
10316 potentially be called.
10317 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10318 body for 'Output when the type is abstract (only the creation of the
10319 body for 'Input is excluded when the type is abstract).
10320 (Stream_Operation_OK): Add an additional condition in the return
10321 statement, so that False will be returned for TTS_Stream_Input if the
10322 associated tagged type is an abstract extension. Add comments for
10324 (Expand_N_Object_Declaration): For the case of a shared passive
10325 variable, insert init proc call only after the shared variable
10326 procedures have been processed, because the IP call needs to undergo
10327 shared passive variable reference expansion, which requires these
10328 procedures to be available (and elaborated).
10330 2007-09-10 Vincent Celier <celier@adacore.com>
10332 * prj-env.ads, prj-env.adb (Create_Mapping_File (Language)): Remove

10337 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
10338 given a box association, the type of the component is discriminated,
10339 and the value of the discriminant is the discriminant of the enclosing
10340 type, retrieve its value from the aggregate itself, where it must have
10343 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10344 to remove other spurious ambiguities on arithmetic operations involving
10345 literals and addresses, on systems where Address is a visible integer
10346 type, when the operator is called in functional notation.
10347 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10348 is legal when the types match, even if the operation is currently
10351 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10353 * sem_ch12.adb (Build_Local_Package): A formal package with no
10354 associations is legal if all formals have defaults. It is not
10355 equivalent to a formal declared with a box.
10357 2007-09-10 Sergey Rybin <rybin@adacore.com>

10390 the N_Indexed_Component case.
10391 <N_Indexed_Component>: Fall through to above case.

10466 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10468 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the

10473 (Write_Entity_Flags): Write the status of flag Is_Raised.
10474 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10475 spurious ambiguities when integer literals appear in the context of an
10476 address type that is a visible integer type.
10478 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10479 exceptions never being raised.
10480 (Analyze_Raise_Statement): When analyzing an exception, mark it as being
10483 2007-08-31 Javier Miranda <miranda@adacore.com>

10486 statement when compiling under restriction No_Exceptions_Proparation.
10488 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10490 * exp_ch3.adb (Build_Record_Init_Proc): If there is a static
10491 initialization aggregate for the type, generate itype references for

10494 2007-08-31 Gary Dismukes <dismukes@adacore.com>
10496 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10497 library-level package renaming, pass the declaration associated with
10498 the renaming's special debug variable to Qualify_Entity_Names to ensure
10499 that its encoded name is properly qualified.
10501 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10502 occurring in the list of entities to qualify, and do not attempt to
10503 traverse an entity list in that case. Variables associated with
10504 ` library-level package renamings can now occur in the table.
10506 * exp_dbug.ads: Revise documentation of the encoding for renaming
10509 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

10512 access type points to an unconstrained array.
10514 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10516 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
10519 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect

10523 to include loop parameters.
10524 (Valid_Conversion): Avoid generation of spurious error message.

10528 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10529 concatenations of string literals into a single literal, in order to
10530 avoid very deep recursion in the front end, which was causing stack
10533 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10534 string, and the right operand is a string literal (the case of "" &
10535 "..."), optimize by avoiding copying the right operand -- just use the
10536 value of the right operand directly.
10538 * stringt.adb (Store_String_Chars): Optimize by growing the
10539 String_Chars table all at once, rather than appending characters one by
10541 (Write_String_Table_Entry): If the string to be printed is very long,
10542 just print the first few characters, followed by the length. Otherwise,
10543 doing "pn(n)" in the debugger can take an extremely long time.
10545 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10546 Store_String_Char with Store_String_Chars.

10561 have not been fully analyzed.
10563 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10565 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10566 flag, for effiency. It is called when analyzing arithmetic operators
10567 and also for actuals in calls that are universal_integers. The flag is
10568 set for the predefined type address, and for any type or subtype
10571 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10572 Universal_Integer, when the formal is a descendent of address and the
10573 call appears in user code.
10574 (Analyze_Selected_Component): if the prefix is a private extension, the
10575 tag component is visible.

10640 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10641 associated with Standard_Debug_Renaming_Type, to be used as the type of
10642 the special variables whose names provide debugger encodings for
10643 renaming declarations.
10645 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10646 (Set_Debug_Renaming_Link): Change to set Node25.

10653 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10654 and literal with creation of a variable of type
10655 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10656 and the entity of the renaming declaration.
10657 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10658 part of the name of a variable that has a Debug_Renaming_Link.
10660 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10661 special type to be associated with variables that provide debugger

10665 Ed Schonberg <schonberg@adacore.com>
10666 Javier Miranda <miranda@adacore.com>
10668 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10669 ancestor part given by an aggregate to test for an unchecked conversion,
10670 since this can occur in some cases when the ancestor part is a function
10671 call, and we don't want to fall into the recursive call to this
10672 procedure in that case.
10674 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10675 stream attributes on limited types to account for user-specified
10676 attributes as well as whether Input (resp. Output) becomes available
10677 due to Read (resp. Write) being available for the type. Change Boolean
10678 variable to the more accurate name
10679 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10680 double-"not" predicate at beginning of return statement to more
10681 understandable form.
10683 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10684 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10685 in a block statement and use that as the first statement of the
10686 expanded return rather than incorrectly using the handled sequence as
10687 the first statement.
10689 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10690 operation, generate an explicit freeze node for it rather than
10691 generating extra formals, to ensure that gigi has the proper order of
10692 elaboration for anonymous subtypes in the signature of the subprograms.
10693 (Build_In_Place_Formal): Move assertion to beginning of loop.
10694 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10695 applied to a function call (occurs for some cases of 'Input).

10697 applied to a function call (occurs for some cases of 'Input).
10699 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10700 2005, generate an extended return statement enclosing the result object
10703 * freeze.adb (Freeze_Record_Type): Extend the current management of
10704 components that are access type with an allocator as default value: add
10705 missing support to the use of qualified expressions of the
10706 allocator (which also cause freezing of the designated type!)
10707 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10708 dispatching operation, since extra formals may be needed by calls to
10709 build-in-place functions (such as stream 'Input).
10711 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10712 formals for 'Constrained and accessibility level in the case of a
10713 predefined dispatching operation.
10715 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10716 point, no need to find the parent node.
10718 2007-08-16 Javier Miranda <miranda@adacore.com>
10720 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10721 and entry barriers.
10723 2007-08-16 Javier Miranda <miranda@adacore.com>
10725 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10726 is not really required and can introduce regression with the debugger.
10727 The original problem is fixed with the patch written for checks.adb.
10729 2007-08-16 Thomas Quinot <quinot@adacore.com>
10731 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10737 Including_Non_Switch set to False.
10738 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10739 Including_Non_Switch set to False.
10741 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10742 parameter Including_Non_Switch, defaulted to True. When
10743 Including_Non_Switch is False, options that are not switches and
10744 appear as relative path are not converted to absolute paths.
10746 2007-08-16 Nicolas Roche <roche@adacore.com>
10748 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

10755 * sem_ch10.adb (Has_With_Clause): If the name of the with clause
10756 currently inspected is a selected component, retrieve the entity of
10758 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
10759 from the immediate ancestor of Main_Unit_Entity.
10760 (Install_Limited_Withed_Unit): Do not install the limited view of
10761 package P if P is reachable through an ancestor chain from package C
10762 and C also has a with clause for P in its body.
10763 (Has_Limited_With_Clause): New routine.
10764 (Has_With_Clause): New routine.
10766 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10768 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10769 generic for an enclosing instance is a global reference, even though
10770 its scope is the enclosing instance.
10772 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10773 Javier Miranda <miranda@adacore.com>

10783 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
10786 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10788 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10789 implements an operation inherited from a progenitor interface, verify
10790 that they are subtype-conformant.

10793 Bob Duff <duff@adacore.com>
10794 Nicolas Setton <setton@adacore.com>
10796 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10797 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10798 the statement which is being resolved comes from a predefined library
10799 unit, all non-predefined library interpretations are skipped.
10800 (Resolve_Op_Concat): If string concatenation was folded in the parser,

10858 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10859 Suppress unmodified in-out parameter warning in some cases
10860 This patch is a also fairly significant change to the way suppressible
10861 checks are handled.
10863 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10864 needed for access to concurrent record types generated by the expander.
10865 (Generate_Range_Check): When generating a temporary to capture the
10866 value of a conversion that requires a range check, set the type of the
10867 temporary before rewriting the node, so that the type is always
10868 properly placed for back-end use.
10869 (Apply_Float_Conversion_Check): Handle case where the conversion is
10871 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10872 for a protected type in order to examine its discriminants.

10879 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10880 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10881 tests optimized out.
10883 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10884 (Get_Allocator_Final_List): For the case of an anonymous access type
10885 that has a specified Associated_Final_Chain, do not go up to the
10887 (Expand_N_Type_Conversion): Test for the case of renamings of access
10888 parameters when deciding whether to apply a run-time accessibility
10890 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10891 aggregate code before allocator, and ahead of declaration for
10892 temporary, to prevent access before elaboration when the allocator is
10893 an actual for an access parameter.
10894 (Expand_N_Type_Conversion): On an access type conversion involving an
10895 access parameter, do not apply an accessibility check when the
10896 operand's original node was an attribute other than 'Access. We now
10897 create access conversions for the expansion of 'Unchecked_Access and
10898 'Unrestricted_Access in certain cases and clearly accessibility should
10899 not be checked for those.
10901 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10902 includes a type conversion of a packed component that has been expanded,
10903 recover the original expression for the object, and use this expression
10904 in the post-call assignment statement, so that the assignment is made
10905 to the object and not to a back-end temporary.
10906 (Freeze_Subprogram): In case of primitives of tagged types not defined
10907 at the library level force generation of code to register the primitive
10908 in the dispatch table. In addition some code reorganization has been
10909 done to leave the implementation clear.
10910 (Expand_Call): When expanding an inherited implicit conversion,
10911 preserve the type of the inherited function after the intrinsic
10912 operation has been expanded.
10914 * exp_ch2.ads, exp_ch2.adb
10915 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10916 of an entry formal appearing in an assignment statement does not assign
10918 (Expand_Current_Value): Instead of calling a routine to determine
10919 whether the prefix of an attribute reference should be optimized or
10920 not, prevent the optimization of such prefixes all together.
10922 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10923 component whose prefix is known to be of an access type is an implicit
10924 dereference and does not assign to the prefix.
10926 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10927 Robert Dewar <dewar@adacore.com>
10929 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10930 itype is visited, make an entry into table to link associated node and
10932 Add comments and correct harmless error in Build_NCT_Hash_Tables
10933 (Array_Aggr_Subtype): Associate each itype created for an index type to
10934 the corresponding range construct, and not to the aggregate itself. to
10935 maintain a one-to-one correspondence between itype and its associated
10936 node, to prevent errors when complex expression is copied.
10937 Fix mishandling of multiple levels of parens
10939 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10940 treatment of limited views uniform for all visible declarations in a
10941 limited_withed package.
10942 (New_Copy_Tree): If hash table is being used and itype is visited,
10943 make an entry into table to link associated node and new itype.
10944 (Resolve_Record_Aggregate): Do not add an others box association for a
10945 discriminated record component that has only discriminants, when there
10946 is a box association for the component itself.
10948 * par-ch4.adb: Fix mishandling of multiple levels of parens
10950 2007-08-14 Robert Dewar <dewar@adacore.com>

10987 to make treatment of limited views uniform for all visible declarations
10988 in a limited_withed package.
10989 Improve warnings for in out parameters
10990 (Set_Related_Interaface/Related_Interface): Allow the use of this
10991 attribute with constants.
10992 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10993 Warn on duplicate pragma Preelaborable_Initialialization
10995 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10996 generation of a freezing node to ensure proper management of null
10997 excluding access types in the backend.
10998 (Create_Extra_Formals): Test base type of the formal when checking for
10999 the need to add an extra accessibility-level formal. Pass the entity E
11000 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
11001 originally being done in a couple of cases), to ensure that the
11002 Extra_Formals list gets set on the entity E when the first entity is
11004 (Conforming_Types): Add missing calls to Base_Type to the code that
11005 handles anonymous access types. This is required to handle the
11006 general case because Process_Formals builds internal subtype entities
11007 to handle null-excluding access types.
11008 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11009 functions that need it, even when not marked Requires_Overriding.
11010 Improve warnings for in out parameters
11011 (Analyze_Function_Return): Warn for disallowed null return
11012 Warn on return from procedure with unset out parameter
11013 Ensure consistent use of # in error messages
11014 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
11015 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
11016 the implicit conversion of the expression done for anonymous access
11017 types. This is required to generate the code of the null excluding
11018 check (if required).
11020 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
11021 A formal parameter is never publicly referenceable outside of its body.
11022 (Check_References): For an unreferenced formal parameter in an accept
11023 statement, use the same warning circuitry as for subprogram formal
11025 (Warn_On_Unreferenced_Entity): New subprogram, taken from
11026 Output_Unreferenced_Messages, containing the part of that routine that
11027 is now reused for entry formals as described above.
11028 (Goto_Spec_Entity): New function
11029 (Check_References): Do not give IN OUT warning for dispatching operation
11030 Improve warnings for in out parameters

11038 Gary Dismukes <dismukes@adacore.com>
11040 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
11041 (Expand_N_Attribute_Reference): Further unify the handling of the
11042 three forms of access attributes, using common code now for all three
11043 cases. Add a test for the case of applying an access attribute to
11044 an explicit dereference when the context is an access-to-interface
11045 type. In that case we need to apply the conversion to the prefix
11046 of the explicit dereference rather than the prefix of the attribute.
11047 (Attribute_Version, UET_Address): Set entity as internal to ensure
11048 proper dg output of implicit importation.
11049 (Expand_Access_To_Type): Removed.
11050 (Expand_N_Attribute_Reference): Merge the code from the three cases
11051 of access attributes, since the processing is largely identical for
11052 these cases. The substantive fix here is to process the case of a
11053 type name prefix (current instance case) before handling the case
11054 of interface prefixes.

11059 Robert Dewar <dewar@adacore.com>
11061 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
11062 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
11063 type that is an anonymous access to controlled object, establish
11064 an associated finalization chain to avoid corrupting the global
11065 finalization list when a dynamically allocated object designated
11066 by such a component is deallocated.
11067 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11068 functions that need it, even when not marked Requires_Overriding.
11069 (Initialize_Tag): Replace call to has_discriminants by call to
11070 Is_Variable_Size_Record in the circuitry that handles the
11071 initialization of secondary tags.
11072 (Is_Variable_Size_Record): New implementation.
11073 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
11074 Suppress_Initialization pragma for a derived type.
11075 (Is_Variable_Size_Record): New subprogram.
11076 (Build_Offset_To_Top_Functions): New implementation that simplifies the
11077 initial version of this routine and also fixes problems causing
11078 incomplete initialization of the table of interfaces.
11079 (Build_Init_Procedure): Improve the generation of code to initialize the
11080 the tag components of secondary dispatch tables.
11081 (Init_Secondary_Tags): New implementation that simplifies the previous
11082 version of this routine.
11083 (Make_DT): Add parameter to indicate when type has been frozen by an
11084 object declaration, for diagnostic purposes.
11085 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
11086 diagnose attemps to freeze a subprogram when some untagged type of its
11087 profile is a private type whose full view has not been analyzed yet.
11088 (Freeze_Array_Type): Generate init proc for packed array if either
11089 Initialize or Normalize_Scalars is set.
11090 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
11091 constructing the new profile, copy the null_exclusion indicator for each
11092 parameter, to ensure full conformance of the new body with the spec.
11094 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
11095 Create wrappers for constructor functions that need it, even when not
11096 marked Requires_Overriding.
11097 (Covers): Handle properly designated types of anonymous access types,
11098 whose non-limited views are themselves incomplete types.
11099 (Add_Entry): Use an entity to store the abstract operation which hides
11101 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
11102 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
11103 initialization aggregate.
11104 (Function_Interp_May_Be_Hidden): Rename to
11105 Function_Interp_Has_Abstract_Op.
11106 (Has_Compatible_Type): Remove machinery that skips interpretations if
11107 they are labeled as potentially hidden by an abstract operator.
11108 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
11109 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
11110 (Write_Overloads): Output the abstract operator if present.
11111 (Add_Entry): Before inserting a new entry into the interpretation table
11112 for a node, determine whether the entry will be disabled by an abstract
11114 (Binary_Op_Interp_May_Be_Hidden): New routine.
11115 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
11117 (Function_Interp_May_Be_Hidden): New routine.
11118 (Has_Compatible_Type): Do not consider interpretations hidden by
11119 abstract operators when trying to determine whether two types are
11121 (Has_Hidden_Interp): New routine.
11122 (Set_May_Be_Hidden_Interp): New routine.
11123 (Write_Overloads): Write the status of flag May_Be_Hidden.

11128 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
11129 types declared in the declarative part of a nested package body or in
11130 the proper body of a stub.
11131 (Set_All_DT_Position): Add missing check to avoid wrong assignation
11132 of the same dispatch table slot to renamed primitives.
11133 (Make_Select_Specific_Data_Table): Handle private types.
11134 (Tagged_Kind): Handle private types.
11135 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
11136 output of implicit importation and exportation.
11137 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11138 first formal of the thunk is always associated with the controlling
11139 type. In addition perform the following code cleanup: remove formal
11140 Thunk_Alias which is no longer required, cleanup evaluation of the
11141 the controlling type, and update the documentation.
11142 Replace occurrence of Default_Prim_Op_Count by
11143 Max_Predef_Prims. Addition of compile-time check to verify
11144 that the value of Max_Predef_Prims is correct.
11145 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11146 (Make_DT): Add parameter to indicate when type has been frozen by an
11147 object declaration, for diagnostic purposes.
11148 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11149 construction of statically allocated dispatch tables.
11150 (Make_DT): In case of library-level tagged types export the declaration
11151 of the primary tag. Remove generation of tags (now done by Make_Tags).
11152 Additional modifications to handle non-static generation of dispatch
11153 tables. Take care of building tables for asynchronous interface types
11154 (Make_Tags): New subprogram that generates the entities associated with
11155 the primary and secondary tags of Typ and fills the contents of Access_
11156 Disp_Table. In case of library-level tagged types imports the forward
11157 declaration of the primary tag that will be declared later by Make_DT.
11158 (Expand_Interface_Conversion): In case of access types to interfaces
11159 replace an itype declaration by an explicit type declaration to avoid
11160 problems associated with the scope of such itype in transient blocks.

11163 Ed Schonberg <schonberg@adacore.com>
11164 Javier Miranda <miranda@adacore.com>
11166 * exp_util.ads, exp_util.adb:
11167 This patch replaces a number of occurrences of explicit tests for N_Null
11168 with calls to Known_Null. This improves tracking of null values, since
11169 Known_Null also catches null constants, and variables currently known to
11170 be null, so we get better tracking.
11171 (Ensure_Defined): create an itype reference only in the scope of the
11173 (Side_Effect_Free): A selected component of an access type that
11174 denotes a component with a rep clause must be treated as not
11175 side-effect free, because if it is part of a linked structure its
11176 value may be affected by a renaming.
11177 (Expand_Subtype_From_Expr): For limited objects initialized with build
11178 in place function calls, do nothing; otherwise we prematurely introduce
11179 an N_Reference node in the expression initializing the object, which
11180 breaks the circuitry that detects and adds the additional arguments to
11181 the called function. Bug found working in the new patch for statically
11182 allocated dispatch tables.
11183 (Is_Library_Level_Tagged_Type): New subprogram.
11184 (Remove_Side_Effects): If the expression of an elementary type is an
11185 operator treat as a function call.
11186 (Make_Literal_Range): If the index type of the array is not integer, use
11187 attributes properly to compute the constraint on the resulting aggregate
11190 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11191 class-wide type whose base type is an incomplete private type, leave
11192 class-wide type unfrozen so that freeze nodes can be generated
11193 properly at a later point.
11194 (Freeze_Entity, array case): Handle case of pragma Pack and component
11195 size attributre clause for same array.
11197 2007-08-14 Vincent Celier <celier@adacore.com>

11251 (Search_Directories): Detect subunits that are specified with an
11252 attribute Body in package Naming. Do not replace a source/unit in the
11253 same project when the order of the source dirs are known. Detect
11254 duplicate sources/units in the same project when the order of the
11255 source dirs are not known.
11256 (Check_Ada_Name): Allow all identifiers that are not reserved words

11821 * table.adb, g-table.adb, g-dyntab.adb (Append): Reimplement in terms
11823 (Set_Item): When the new item is an element of the currently allocated
11824 table passed by reference, save a copy on the stack if we're going
11825 to reallocate. Also, in Table.Set_Item, make sure we test the proper
11826 variable to determine whether to call Set_Last.

11839 Thomas Quinot <quinot@adacore.com>
11841 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11842 derived type with interface progenitors use the analyzed formal as the
11843 parent of the actual, to create renamings for all the inherited
11844 operations in Derive_Subprograms.
11845 (Collect_Previous_Instances): new procedure within of
11846 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11847 unit being loaded, to ensure that the generation of global symbols is
11848 consistent in different compilation modes.
11849 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11850 takes progenitor types into account.
11851 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11852 traversing over the primitives of the formal and actual types to locate
11853 any abstract subprograms of the actual type that correspond to a
11854 nonabstract subprogram of the formal type's ancestor type(s), and issue
11855 an error if such is found.
11856 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11857 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11858 Remove bogus guard around calls to Inherit_Context.
11859 (Reset_Entity): If the entity is the selector of a selected component
11860 that denotes a named number, propagate constant-folding to the generic
11861 template only if the named number is global to the generic unit.
11862 (Set_Instance_Env): Only reset the compilation switches when compiling
11863 a predefined or internal unit.
11865 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11867 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
11868 parameter to determine whether operation applies to the prefix.
11869 (Complete_Object_Operation): If actual has an access type and
11870 controlling formal is not an in_parameter, reject the actual if it is
11871 an access_to_constant type.
11872 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11873 type, the candidate operations are found in the scope of declaration of
11874 the type, because the type has no primitive subprograms.
11875 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11876 a private extension, only examine visible components before trying to
11877 analyze as a prefixed call.
11878 Change Entity_List to Type_To_Use, for better readability.
11879 (Has_Fixed_Op): Use base type when checking whether the type of an
11880 operator has a user-defined multiplication/division
11881 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
11882 user-defined operators are available for fixed-point types.

11885 Ed Schonberg <schonberg@adacore.com>
11887 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
11888 formal At_Any_Place indicating, when True, that we want to test for
11889 availability of the stream attribute at any place (as opposed to the
11890 current visibility context only).
11891 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11892 purpose of enforcing E.2.2(8) only if it is not available at any place.
11893 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11894 when checking the legality of an extension aggregate in a preelaborable
11895 package. Treat the literal null as a valid default expression in a
11896 component declaration for a type with preelaborable initialization.
11897 A limited interface is a legal progenitor for the designated type of a
11898 remote access to class-wide type.

11906 (Find_Direct_Name): Add comment about Generate_Reference incorrectly
11907 setting the Referenced_As_LHS flag for entities that are implicitly
11909 (Find_Type): If the type is an internally generated incomplete type,
11910 mark the full view as referenced, to prevent spurious warnings.
11911 (Find_Selected_Component, Has_Components): Handle properly non-limited
11912 views that are themselves incomplete types.
11913 Handle interfaces visible through limited-with clauses.
11914 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11915 subprogram generic actual for which we have generated a renaming.
11916 Warn when the renaming introduces a homonym of
11917 the renamed entity, and the renamed entity is directly visible.

11920 Hristian Kirtchev <kirtchev@adacore.com>
11922 * sem_res.adb (Resolve_Allocator): Propagate any coextensions that
11923 appear in the subtree to the current allocator if it is not a static
11925 (Resolve_Allocator): Perform cleanup if resolution has determined that
11926 the allocator is not a coextension.
11927 (Resolve): Skip an interpretation hidden by an abstract operator only
11928 when the type of the interpretation matches that of the context.
11929 (Resolve): When looping through all possible interpretations of a node,
11930 do not consider those that are hidden by abstract operators.
11931 (Resolve_Actuals): When verifying that an access to class-wide object
11932 is an actual for a controlling formal, ignore anonymous access to
11933 subprograms whose return type is an access to class_wide type.
11934 (Resolve_Slice): If the prefix of the slice is a selected component
11935 whose type depends on discriminants, build its actual subtype before
11936 applying range checks on the bounds of the slice.
11937 (Valid_Conversion): In an instance or inlined body, compare root types,
11938 to prevent anomalies between private and public views.
11939 (Resolve): Improve error message for ambiguous fixed multiplication
11940 expressions that involve universal_fixed multiplying operations.

11956 * exp_dist.adb (PolyORB_Support.Build_TypeCode_Function): When creating
11957 typecode parameters for a union (in a variant record), remove
11958 extraneous layer of Any wrapping for member label.
11959 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
11960 elabration statements, register the package with the name server
11961 at the beginning, not at the end, of the elaboration statements so
11962 that they can create remote access to subprogram values that designate
11963 remote subprograms from the package.
11965 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
11967 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
11968 values to compute the number of seconds since the Unix Epoc in order to
11969 account for Daylight Savings Time. Perform special processing for dates
11970 that are earlier than the Unix Epoc to obtain a negative number.

11982 recorded in the ALI file.
11983 Pass -fsjlj to the linker if it is GCC and --RTS=sjlj has been recorded.

12149 units being loaded to detect circularities. A circularity may be
12150 present even if the current chain of pending units to load starts from
12151 a limited_with_clause.
12153 * lib-load.ads: Change profile of Load_Unit to use a with_clause
12154 rather than a boolean flag, in order to detect circularities in
12157 * par-load.adb: Use current with_clause in calls to Load_Unit, rather
12158 than propagating the From_Limited_With flag, in order to handle
12159 properly circularities involving with_clauses.
12161 2007-08-14 Nicolas Setton <setton@adacore.com>

12173 Add s-osinte-vxworks-kernel.adb to the target pairs of the
12174 kernel run-time lib for VxWorks 6, which would provide a different
12175 implementation for Task_Cont and Task_Stop than the VxWorks 5 version.
12176 x86-solaris section (EH_MECHANISM): Set to -gcc, as this port is now
12177 running ZCX by default.
12178 Add g-sttsne-locking to LynxOS version.
12179 Remove g-sttsne-vxworks.ads; use g-sttsne-locking.ads instead.

13016 store the system's allocator return value there.
13017 (build_call_alloc_dealloc): When releasing a super-aligned object,
13018 retrieve the system's allocator return value from where build_allocator
13019 has stored it, just ahead of the adjusted address we are passed.
13020 (build_call_raise): Handle properly the generation of line numbers when
13021 the node is marked No_Location.
13022 (compare_elmt_bitpos): Use tree_int_cst_compare. Stabilize the sort

13047 ((destructor)) for adafinal, even when switch -a is used.
13048 Do not issue pragma Linker_Destructor for adafinal when switch -a is
13050 (Gen_Object_Files_Options): Add formatting of Linker Options, when
13051 Output_Linker_Option_List is set. Suppress this formatting when

13082 constrained by a current instance.
13083 (Activate_Division_Check): New procedure
13084 (Activate_Overflow_Check): New procedure
13085 (Activate_Range_Check): New procedure
13086 Call these new Activate procedures instead of setting flags directly
13087 (Apply_Array_Size_Check): Removed, no longer needed.
13088 Code clean up: remove obsolete code related to GCC 2.
13089 (Get_E_Length): Protect against bomb in case scope is standard
13090 (Selected_Range_Checks): If the node to be checked is a conversion to
13091 an unconstrained array type, and the expression is a slice, use the
13092 bounds of the slice to construct the required constraint checks.
13093 Improve NOT NULL error messages
13094 (Apply_Constraint_Check): If the context is a null-excluding access
13095 type, diagnose properly the literal null.

13111 Arnaud Charlet <charlet@adacore.com>
13113 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
13114 applicable to types that have the With_Type flag set. Returns the
13115 non-limited view of the type, if available, otherwise the type itself.
13116 For class-wide types, there is no direct link in the tree, so we have
13117 to retrieve the class-wide type of the non-limited view of the Etype.
13118 New attributes Static_Initialization and Static_Elaboration_Desired.
13119 Remove the pragma Thread_Body, and the associated flag
13120 Is_Thread_Body in entities, and all related code.
13121 (Suppress_Value_Tracking_On_Call): New flag
13122 E_Exception has Esize and Alignment fields
13123 (Universal_Aliasing): New function.

13133 (Original_Access_Type): Remove, not needed.
13134 (Root_Type): Handle properly subtypes of class-wide-types.
13137 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13138 class-wide types visible through limited-with clauses.
13139 (Try_Primitive_Operation): When examining all primitive operations of a
13140 tagged type, do not consider subprograms labeled as hidden unless they
13141 belong to a private generic type with a tagged parent.
13142 (Try_Object_Operation): Extensive rewriting, to handle properly various
13143 overloading cases, when several ancestors may have class-wide operations
13144 that are possible candidates, and when the overloaded functions return
13145 array types and have defaulted parameters so that the call may be
13146 interpreted as an indexing.
13147 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13148 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13149 successive actuals before analyzing the call itself.
13150 (Try_Primitive_Operation): A primitive operation is compatible with the
13151 prefix if the prefix has a synchronized type and the type of the formal
13152 is its corresponding record, as can be the case when the primitive
13153 operation is declared outside of the body of the type.
13154 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13155 perform homonym traversal, looking for class-wide operation matches
13156 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13157 access parameters are now restricted to anonymous access types.
13158 (Mark_Allocator): An allocator with a discriminant association parent is
13160 (Try_One_Prefix_Interpretation): If the type of the object is
13161 incomplete, as can be happen when it is a limited view obtained through
13162 a limited_with_clause, the selected component is not part of a prefixed
13164 (Complete_Object_Operation): Diagnose properly an object that is not
13165 aliased when the corresponding controlling formal is an access
13167 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13168 ambiguous calls in prefixed notation, where two primitives differ only
13169 in that the controlling argument of one is an access parameter.
13171 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13172 whether a function that returns an unconstrained type can be inlined.
13173 (Process_Formals): Diagnose properly the illegal use of an incomplete
13174 type in the profile of an access_to_subprogram declaration.
13175 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13176 operations are attached to the corresponding record.
13177 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13178 When processing a primitive of a concurrent type which implements an
13179 interface change the type of all controlling formals to that of the
13180 corresponding record type.
13181 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13182 to determine the tagged type to which a primitive belongs.
13183 (Check_Conventions): Capture condition to ignore a primitive operation
13184 (which is shared between the loop in Check_Conventions and the one in
13185 Check_Convention) in a new local function Skip_Check.
13186 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13187 confusion with Check_Conventions' own Prim_Op local variable.
13188 (Create_Extra_Formals): Test for a tagged result type rather than a
13189 controlling result when determining whether to add a BIP_Alloc_Form
13190 formal and a BIP_Final_List formal to the function.
13191 (Check_Conformance); For parameters that are anonymous access types,
13192 subtype conformance requires that the not null and the constant
13193 indicators must match
13194 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13195 to retrieve the appropriate type when processing a concurrent type
13196 declared within a generic. Minor comment reformatting. Change invocation
13197 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13199 (Analyze_Subprogram_Body): If the return type of a function is an
13200 anonymous access to the limited view of a class-wide type, and the
13201 non-limited view of the type is available, update the type of the
13202 function so that code can be generated.
13203 (Process_Formals): In case of access-subtype itype whose designated
13204 type is also an itype (situation that happens now with access to
13205 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13206 attribute to avoid backend problems.
13207 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13208 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13209 anonymous types' designated types are same before testing
13210 Subtypes_Statically_Match.
13211 (Create_Extra_Formals): Test for a named access parameter that is a
13212 controlling formal as an additional condition for adding an
13213 accessibility level formal. This can occur in the subp type created for
13214 dispatching calls in Expand_Dispatching_Call, and allows calling
13215 Create_Extra_Formals from that procedure rather than special-casing the
13216 extra formals there.
13217 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13218 when the function has a controlling result.
13219 (Check_Returns): Add much more knowledge of the optimization of local
13220 raise statements to gotos, to retain proper warnings in this case.
13221 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13222 nodes when looking for last statement.
13224 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13225 class-wide types visible through limited with clauses.
13226 (Add_One_Interp): If the operands are anonymous access types, the
13227 predefined operator on universal_access is immediately visibles
13228 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13229 other anonymous access types.
13230 (Disambiguate): Take into account CIL convention.
13231 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13233 2007-06-06 Robert Dewar <dewar@adacore.com>

13238 Fix lower bound of tables.
13241 * nlists.adb: Ditto.
13242 (Prev_Node, Next_Node): Change index type to Int so that it properly
13243 covers the range First_Node_Id - 1 up.

13250 * exp_aggr.ads, exp_aggr.adb:
13251 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13252 in extension aggregates.
13253 (Flatten): Other conditions being met, an aggregate is static if the
13254 low bound given by component associations is different from the low
13255 bound of the base index type.
13256 (Packed_Array_Aggregate_Handled): If the component type is itself a
13257 packed array or record, the front-end must expand into assignments.
13258 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13259 Init_Pr, instead of Ancestor_Is_Expression.
13260 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13261 coextension chain root, either generate a list controller or use the
13262 already existing one.
13263 (Static_Array_Aggregate): New procedure to construct a positional
13264 aggregate that can be handled by the backend, when all bounds and
13265 components are compile-time known constants.
13266 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13267 types covering interface types into assignments.
13268 (Replace_Type): move to Build_Record_Aggr_Code.
13269 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13270 interface type, convert to the definite type of the aggregate itself,
13271 so that needed components are visible.
13272 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13273 components and the context is an extended return statement do not
13274 create a transient block for it, to prevent premature finalization
13275 before the return is executed.
13276 (Gen_Assign): Do not generate a call to deep adjust routine if the
13277 component type is itself an array of controlled (sub)-components
13278 initialized with an inner aggregate.
13279 (Component_Check): New name for Static_Check. This name is now more
13280 appropriate, and documentation is added which was missing.
13281 (Component_Check): Add test for bit aligned component value
13282 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13283 Tagged_Comps, name is more appropriate given added function below.
13284 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

13290 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13291 Terminated: Add unchecked type conversion from System.Address to
13292 System.Tasking.Task_Id when calling the predefined primitive
13294 Disable new Ada 05 accessibility check for JVM.NET targets, which
13295 cannot be implemented in a practical way.
13296 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13297 the sources always references the tag of the actual object. Therefore,
13298 if 'Tag is applied in the sources to class-wide interface objects we
13299 generate code that displaces "this" to reference the base of the object.
13300 (Expand_N_Attribute_Reference, case Size): Return specified size if
13301 known to front end.
13302 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13303 has code that displaces the pointer of the object to manage interface
13304 types. However this code must not be executed when the prefix is a
13305 subprogram. This bug caused the wrong expansion of the internally
13306 generated assignment that fills the dispatch table when the primitive
13307 is a function returning a class-wide interface type.
13308 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13309 Set_Attribute_Name for Name_Unaligned_Valid.
13311 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13312 Gary Dismukes <dismukes@adacore.com>
13314 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13315 If the initialization is the equivalent aggregate of the initialization
13316 procedure of the type, do not remove it.
13317 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13318 initialized to null from having their expression reset to empty and

13328 (Expand_Current_Value): Do not replace occurences of attribute
13329 references where the prefix must be a simple name.
13331 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13332 Namet. Add new arrays Attribute_Name_Modifies_Prefix and

13340 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13341 constrained subtype for a nominal unconstrained type, use its base type
13342 to check for conformance with the context.
13343 (Resolve_Attribute): Remove test of the access type being associated
13344 with a return statement from condition for performing accessibility
13345 checks on access attributes, since this case is now captured by
13346 Is_Local_Anonymous_Access.
13347 (Analyze_Access_Attribute): Set Address_Taken on entity
13348 (Analyze_Attribute, case Address): Set Address_Taken on entity
13349 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13350 validating an access attribute whose prefix is a current instance.
13351 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13352 applied to dispatching operations, if freezing is required then we set
13353 the attribute Has_Delayed_Freeze in the prefix's entity.
13354 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13355 current scope if access of local subprogram taken
13356 (Analyze_Access_Attribute): Check legality of self-reference even if the
13357 expression comes from source, as when a single component association in
13358 an aggregate has a box association.
13359 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13360 the prefix if it is a protected operation and the attribute is
13361 Unrestricted_Access.
13362 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13363 reference to the base type of the context, to force a constraint check
13364 when the context is an access subtype with an explicit constraint.
13365 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13366 node is rewritten as an interface conversion. leave unanalyzed after
13367 resolution, to ensure that type checking against the context will take

13372 Robert Dewar <dewar@adacore.com>
13374 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13375 wrapper when the full view of the controlling type of an inherited
13376 function that dispatches on result implements interfaces.
13377 (Expand_N_Object_Declaration): In cases where the type of the
13378 declaration is anonymous access, create finalization list for it.
13379 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13380 if the object has no explicit initialization, to match description of
13381 functionality of pragam Persistent_BSS.
13382 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13383 new function to build static aggregates, to replace initialization call
13384 when static initialization is desired.
13385 (Freeze_Type): Generate a list controller for an access type whenever
13386 its designated type has controlled anonymous access discriminants.
13387 (Build_Equivalent_Aggregate): New procedure to compute a static
13388 aggregate to be used as default initialization for composite types,
13389 instead of a generating a call to the initialization procedure for the
13391 (Build_Initialization_Call): When available, replace a call to the
13392 initialization procedure with a copy of the equivalent static aggregate
13394 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13395 declarations for objects of a class-wide interface type, rather than
13396 just identifiers, to prevent visibility problems.
13397 (Expand_N_Object_Declaration): When expanding the declaration for an
13398 object of a class-wide interface type, preserve the homonym chain of
13399 the original entity before exchanging it with that of the generated
13400 renaming declaration.
13401 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13402 active, because there is no way to handle the exception.
13403 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13404 to do a minimum decoration of the Access_Disp_Table list.
13405 (Expand_Record_Controller): Avoid the addition of the controller between
13406 the component containing the tag of a secondary dispatch table and its
13407 adjacent component that stores the offset to the base of the object.
13408 This latter component is only generated when the parent type has
13409 discriminants ---documented in Add_Interface_Tag_Components).
13410 (Apply_Array_Size_Check): Removed, no longer needed.
13411 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13412 components, create a Master_Entity for it only if it contains tasks.

13422 if Has_Init_Expression set.
13423 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13424 Register_Primitive, which provides the same functionality.
13425 (Requires_Init_Proc): Return false in case of interface types.
13426 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13428 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13429 is always associated with a predefined primitive because the internal
13430 entities associated with interface types are not predefined primitives.
13431 Therefore, the call to Is_Internal is replaced by a call to the
13432 function Is_Predefined_Dispatching_Operation.
13433 (Make_Eq_If): When generating the list of comparisons for the
13434 components of a given variant, omit the controller component that is
13435 present if the variant has controlled components.

13441 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13442 handle the creation of finalization lists and calls for nested
13443 coextensions when the root of the chains is part of a return statement.
13444 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13446 (Expand_Record_Equality): Skip components that are interface types.
13447 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13448 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13449 with Rewrite_Coextension. Change the condition for detecting coextension
13451 (Is_Local_Access_Discriminant): Removed.
13452 (Rewrite_Coextension): New routine which rewrites a static coextension
13453 as a temporary and uses its unrestricted access in the construction of
13455 (Complete_Coextension_Finalization): New routine. Generate finalization
13456 attachment calls to all delayed coextensions.
13457 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13458 the allocator is not a coextension itself and has delayed coextensions.
13459 If the current allocator is controlled, but also a coextension, delay
13460 the generation of the finalization attachment call.
13461 Rename local variable "Node" to "Nod" in order to avoid confusion with
13463 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13464 limited types that are not inherently limited. Such an allocator is
13465 illegal, but is generated by the expander for a return statement, to
13466 copy the result onto the secondary stack. This is the only case where a
13467 limited object can be copied. Generate code to displace the pointer
13468 to the object if the qualified expression is a class-wide interface
13469 object. Such displacement was missing and hence the copy of the object
13471 (Apply_Accessibility_Check): Handle allocated objects initialized in
13473 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13474 and Expand_Allocator_Expression. Allocating class-wide interface objects
13475 this routine displaces the pointer to the allocated object to reference
13476 the component referencing the corresponding secondary dispatch table.
13477 Expand_Allocator_Expression): Add missing support to allocate class-wide
13478 interface objects initialized with a qualified expression.
13479 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13480 function result type, and use the finalization list associated with the
13481 function scope in that case (such an anonymous type should not be
13482 treated like an access parameter's type).
13484 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13485 Gary Dismukes <dismukes@adacore.com>
13486 Javier Miranda <miranda@adacore.com>
13488 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13489 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13490 required exception handler.
13491 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13492 properly the case of a function whose return type is a limited
13493 class-wide interface type. Modify the code of the accessibility
13494 check to handle class-wide interface objects. In this case we need to
13495 displace "this" to reference the primary dispatch table to get access
13496 to the TSD of the object (to evaluate its accessibility level).
13497 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13498 rather than a controlling result as one of the conditions for
13499 generating tests of the implicit BIP_Alloc_Form formal. The
13500 initialization assignment is also handled according to whether the
13501 result is tagged instead of controlling.
13502 In the case where the init assignment is inserted in the "then" part of
13503 the allocation conditional, rewrite the target to be a dereference of
13504 the implicit BIP_Object_Access formal.
13505 If the returned value is unconstrained and created on the secondary
13506 stack, mark the enclosing block and function so that the secondary
13507 stack is not reclaimed on return.
13508 Treat returns from functions with controlling results similarly to
13509 returns from functions with unconstrained result subtypes.
13510 If the object returned is unconstrained, and an allocator must be
13511 created for it, analyze the allocator once the block for the extended
13512 return is installed, to ensure that finalizable components
13513 of the expression use the proper finalization list. Guard the call to
13514 Move_Final_List with a check that there is something to finalize.
13515 (Make_Tag_Ctrl_Assignment): Use "old" handling
13516 of controlled type assignment for virtual machines, since new code uses
13517 unsupported features (such as direct access to bytes in memory).
13519 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13520 Ed Schonberg <schonberg@adacore.com>
13522 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13523 accessibility actual, check for the case of an aliased object that has
13524 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13525 we fall into processing for the attribute rather than the name of the
13527 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13528 formal has its address taken in the body, create a temporary to capture
13529 value. If the return type is a limited interface, do not treat the
13530 return value as Controlled.
13531 (Is_In_Place_Function): If the return type is a limited interface,
13532 treat as returning in place. The actual returned object may not always
13533 be limited, but the caller has to assume that it is returned in place.
13534 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13535 context of an allocator, use the correct finalization chain (that is,
13536 the chain belonging to the access type, rather than the chain belonging
13537 to the current scope).
13538 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13539 result type rather than a controlling result as a precondition for
13540 adding an allocation form actual to a build-in-place call.
13541 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13542 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13543 primitive in the dispatch tables. This work is now done by Make_DT when
13544 the type is frozen.
13545 (Register_Predefined_DT_Entry): Removed.
13546 (Add_Return): If end label is not present, use sloc of last statement
13547 for generated return statement in procedure, for better gdb behavior
13549 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13550 object address nodes to ensure proper processing by routines like
13552 (Expand_Call): Fix generation of validity check for parameter
13553 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13554 the allocation form parameter if the result subtype is constrained,
13555 except when the function has a controlling result.
13556 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13557 rather than Is_Controlled and Has_Controlled_Component, since we want to
13558 include class-wide result types in this treatment. Also test for a
13559 controlling result, since that also requires passing a finalization
13561 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13562 even when the result subtype is constrained, to handle calls involving
13563 controlling results.
13564 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13565 is now called even when the result subtype is constrained, to handle
13566 calls involving controlling results.
13567 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13568 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13569 now performs the test).
13570 (Make_Build_In_Place_Call_In_Object_Declaration):
13571 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13572 constrained, to handle calls involving controlling results.
13573 (Add_Return): Accomodate rewritten pattern from local raise to goto
13574 transformation, so that we still recognize an transfer statement
13575 and do the right thing here in that case.
13576 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13577 and end of subprogram code.
13578 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13579 support for primitives that are functions (without formals) with a
13580 controlling result.
13581 (Inherited_From_Formal): If the actual subtype has not generic parent
13582 type, it is not an actual for a formal derived type, and there is no
13583 operation to inherit from the formal.
13585 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13586 Thomas Quinot <quinot@adacore.com>
13588 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13589 inserted cleanup code appropriately for GDB use.
13590 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13591 exception handler for Deep_Adjust or Deep_Finalize.
13592 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13593 Raise_From_Controlled_Operation is available, use a call to that
13594 subprogram instead of a plain "raise Program_Error" node to raise
13595 Program_Error if an exception is propagated from an Adjust or Finalize
13597 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13598 appears in the optional statement list of a triggering alternative, the
13599 scope actions can be inserted directly there, and not in the list that
13600 includes the asynchronous select itself.
13602 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13603 Robert Dewar <dewar@adacore.com>
13604 Hristian Kirtchev <kirtchev@adacore.com>
13606 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13607 generated exception handler appropriately when debugging generated code.
13608 Deal properly with No_Exception_Propagation restriction mode.
13609 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13610 System.Address to System.Tasking.Task_Id when processing the result of
13611 the predefined primitive _disp_get_task_id.
13612 (Expand_N_Asynchronous_Select): Clarify comment.
13613 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13614 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13615 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13616 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13617 privals and for generated call to Complete_Entry_Body, for better gdb
13619 (Copy_Result_Type): Utility to construct a parameter and result profile
13620 for protected functions whose return type is an anonymous access to
13622 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13624 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13625 point when the local-raise-to-goto transformation has taken place.
13627 2007-06-06 Javier Miranda <miranda@adacore.com>
13628 Nicolas Setton <setton@adacore.com>
13630 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13631 functionality when the backend is generating code.
13632 Otherwise any serious error
13633 reported by the backend calling the frontend routine Error_Msg
13634 changes the Compilation_Mode to Check_Semantics, disables the
13635 functionality of this routine and causes the generation of
13636 spureous additional errors.
13638 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13639 debugging information now generated by the compiler for fat-pointer
13641 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13643 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13645 2007-06-06 Thomas Quinot <quinot@adacore.com>
13647 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13648 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13649 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13650 For a remote call to a function with a classwide return type, apply an
13651 E.4(18) check to the returned value.
13652 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13653 stream attributes of the designated type of an RACW, as they are not
13654 dispatching primitive operations.
13656 2007-06-06 Geert Bosch <bosch@adacore.com>
13658 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13660 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13662 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13663 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13665 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13667 2007-06-06 Javier Miranda <miranda@adacore.com>
13669 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13670 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13672 2007-06-06 Javier Miranda <miranda@adacore.com>
13674 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13675 deallocation of class-wide interface objects.
13676 (Expand_Dispatching_Constructor_Call): Take into account that if the
13677 result of the dispatching constructor is an interface type, the
13678 function returns a class-wide interface type; otherwise the returned
13679 object would be actual. The frontend previously accepted returning
13680 interface types because Expand_Interface_Actuals silently performed
13681 the management of the returned type "as if" it were a class-wide
13683 (Expand_Dispatching_Constructor_Call): Replace call to
13684 Make_DT_Access_Action by direct call to Make_Function_Call.
13686 2007-06-06 Robert Dewar <dewar@adacore.com>
13687 Ed Schonberg <schonberg@adacore.com>
13689 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13690 compute masking constant, since we now set Esize properly to the
13692 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13693 to match the alignment.
13694 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13695 packed arrays of 8 bits or less.
13697 * freeze.adb (Freeze_Entity): When freezing the formals of a
13698 subprogram, freeze the designated type of a parameter of an access type
13699 only if it is an access parameter.
13700 Increase size of C convention enumeration object
13701 (Freeze_Entity, array type case): Make sure Esize value is properly
13702 adjusted for the alignment if it is known.
13703 (Freeze_Entity, array type case): When checking bit packed arrays for
13704 the size being incorrect, check RM_Size, not Esize.
13705 (Freeze_Record_Type): Check for bad discriminated record convention
13706 (In_Exp_Body): Return true if the body is generated for a subprogram
13707 renaming, either an attribute renaming or a renaming as body.
13708 (Check_Itype): If the designated type of an anonymous access component
13709 is a non-protected subprogram type, indicate that it is frozen, to
13710 prevent out-of-scope freeze node at some subsequent call.
13711 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13712 only if the subprogram is neither imported nor exported, as well as the
13713 NCA descriptor class if the subprogram is exported.

13720 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13721 default initialization on an imported object, when there is no
13722 initialization call generated for it.
13723 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13726 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13727 Static_Elaboration_Desired.
13728 Remove pragma Thread_Body.
13729 Implement a new pragma No_Body
13730 Removes the Explicit_Overriding pragma
13731 Remove Optional_Overriding pragma
13732 (Prag): Deal with Universal_Aliasing.
13733 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13734 Pragma_CIL_Constructor): New names.
13736 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13737 uses the equivalent aggregate of a type must be treated as an implicit
13739 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13740 has none of the other categories.
13741 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13742 to apply Import to an object renaming declaration.
13744 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13745 from a C++ class should be declared as limited and that it will be
13746 considererd limited.
13747 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13748 should be declared as limited and that it will be considererd limited.
13749 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13750 (Analyze_Pragma, case Export): Diagnose export of enumeration literal

13755 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
13756 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
13757 case of JVM or .NET targets, and compiling user code.
13758 Add debugging convenience routine rv

13762 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
13763 are interface type.

13767 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
13768 set to value that does not match base type size.

13772 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13773 object of a limited type can be initialized with a call to a function
13774 that returns in place. If the limited type has unknown discriminants,
13775 and the underlying type is a constrained composite type, build an actual
13776 subtype from the function call, as is done for private types.
13777 (Side_Effect_Free): An expression that is the renaming of an object or
13778 whose prefix is the renaming of a object, is not side-effect free
13779 because it may be assigned through the renaming and its value must be
13780 captured in a temporary.
13781 (Has_Controlled_Coextensions): New routine.
13782 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13783 as is done for other limited types.
13784 (Non_Limited_Designated_Type): new predicate.
13785 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
13787 Remove all handling of with_type clauses.

13791 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
13792 checksum if the main source could not be parsed.

13794 the parent unit is a renaming when the parent is itself a child unit.
13795 Remove handling of with_type clauses.
13797 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

13830 Ed Schonberg <schonberg@adacore.com>
13832 * g-comlin.ads, g-comlin.adb:
13833 Add new warning for renaming of function return objects
13835 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
13836 (Tree_Read): Use size of object instead of type'object_size, since the
13837 latter is incorrect for packed array types.
13838 (Tree_Write): Same fix
13840 * opt.ads: Add new warning for renaming of function return objects
13841 (Generating_Code): New boolean variable used to indicate that the
13842 frontend as finished its work and has called the backend to process

13851 (Warn_On_Unrepped_Components): New flag.
13853 * sem_ch8.adb (Check_Library_Unit_Renaming): Check that the renamed
13854 unit is a compilation unit, rather than relying on its scope, so that
13855 Standard can be renamed.
13856 (Analyze_Object_Renaming): Add new warning for renaming of function
13858 Also reject attempt to rename function return object in Ada 83 mode.
13859 (Attribute_Renaming): In case of tagged types, add the body of the
13860 generated function to the freezing actions of the type.
13861 (Find_Type): A protected type is visible right after the reserved word
13862 "is" is encountered in its type declaration. Set the entity and type
13863 rather than emitting an error message.
13864 (New_Scope): Properly propagate Discard_Names to inner scopes
13865 (Check_Nested_Access): New procedure.
13866 (Has_Nested_Access, Set_Has_Nested_Access): New procedures.

13880 * g-debpoo.ads, g-debpoo.adb (Free_Physically.Free_Blocks): Use the
13881 absolute value of Header.Block_Size when displaying the freed physical
13883 (Allocate): Compute Storage_Address using Integer_Address, not
13884 Storage_Offset, because the range of Storage_Offset may not be large
13886 (Configure): New parameter Low_Level_Traces
13887 (Allocate, Deallocation, Free_Physically): Added low-level traces
13888 (Configure): new parameter Errors_To_Stdout.

14306 association, and the corresponding record component has a default
14307 expression, always copy the default expression, even when the

15408 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15410 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15411 the master of the created object is the innermost enclosing statement.
15412 (Remove_Conversions): For a binary operator, check if type of second

15576 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
15577 "abstract subprograms must be visible" message, whether or not the type

15647 "X'Unrestricted_Access = Y'Access" and so forth to match.

15655 attempt to derive from a synchronized tagged type.

15660 that use (a subtype of) the class-wide type of the enclosing type.
15661 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15662 Derived_Type for Prev formal on call to
15663 Check_Anonymous_Access_Components rather than Empty.
15664 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15665 a record extension in deciding whether to create a class-wide type,

15668 to stand-alone object declarations as well as component declarations.

15673 the associated_node for the itype is the type declaration itself.

15711 (Compile_Sources): Do nothing, not even check if the source is up to
15712 date, if its project is externally built.
15713 (Compile): When compiling a predefined source, add -gnatpg
15714 as the second switch, after -c.
15715 (Compile_Sources): Allow compilation of Annex J renames without -a
15716 (Is_In_Object_Directory): Check if the ALI file is in the object
15717 even if there is no project extension.
15718 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
15719 gnatbind if the ALI file effectively exists.
15720 (Initialize): Add the directory where gnatmake is invoked in front of
15721 the path if it is invoked from a bin directory, even without directory

15746 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15747 when -gnatg is not specified.

15777 (Convert_Aggr_In_Allocator): If the allocator is for an access
15778 discriminant and the type is controlled. do not place on a finalization
15779 list at this point. The proper list will be determined from the

15782 initialize record controller if needed, before the components, to ensure
15783 that they are properly finalized.

15799 parameter of the containing subprogram.
15800 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15801 under No_Dispatching_Calls restriction. During the semantic analysis
15802 we already notified such violation.
15803 (Tagged_Membership): Constant folding. There is no need to check
15804 the tag at run-time if the type of the right operand is non
15805 class-wide abstract.

15820 initialize most the TSD components by means of an aggregate.
15821 Modify the declaration of the object containing the TSD
15822 because we now expand code that has a higher level of abstraction.
15823 The TSD has a discriminant containing the Inheritance Depth Level,
15824 value that is used in the membership test but also to fix the size
15825 of the table of ancestors.
15826 (Expand_Interface_Conversion): Insert function body at the closest place
15827 to the conversion expression, to prevent access-before-elaboration
15828 errors in the backend.

15854 (Expand_Dispatching_Call): Replace generation of call to the run-time
15855 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15856 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15858 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15859 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

15873 check violation of restriction No_Dispatching_Calls.
15874 (Check_Controlling_Type): A formal of a tagged incomplete type is a

15881 specify Any_Limited_Interface, and this functionality is already
15882 provided by the function Has_Abstract_Interfaces.
15883 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15884 support concurrent types implementing interfaces.
15885 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15886 specify kind Any_Limited_Interface, and this functionality is already

15889 CW_Or_Controlled_Type whenever the issue is related to
15890 using or not the secondary stack.

15906 anonymous, use finalization list of enclosing dynamic scope.
15907 (Expand_N_Package_Declaration): For a library package declaration
15908 without a corresponding body, generate RACW subprogram bodies in the
15909 spec (just as we do for the task activation call).
15910 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15911 Is_Abstract_Type. Make sure these are called only when appropriate.
15912 Remove all code for DSP option

15930 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15931 a protected version of an operation declared in the private part of
15932 a protected object, because they may be invoked through a callback.
15933 (Set_Privals): If the type of a private component is an anonymous access
15934 type, do not create a new itype for each protected body.
15935 If the body of a protected operation creates
15936 controlled types (including allocators for class-widetypes), the
15937 body of the corresponding protected subprogram must include a

15944 for a possible overriding candidate.
15945 (Build_Simple_Entry_Call): Set No_Initialization on the object used to

15951 Pablo Oliveira <oliveira@adacore.com>
15953 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):

15956 Build_From_Any_Call.
15957 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15958 E_Constant, depending upon Variable formal.
15959 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,

15964 the unit being compiled is the one that contains the stub type.
15965 Change primitive operation name for the RACW associated with a RAS
15966 from Call to _Call so it cannot clash with any legal identifier.
15967 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15969 (Append_RACW_Bodies): New subprogram.
15970 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15971 Add_Receiving_Stubs_To_Declarations functions.
15972 When expanding a package body, this list correspond to the

15977 registering the receiving stubs at the end of the 'Stmts' list.
15978 (RCI_Package_Locator): Pass the new Version generic formal when
15979 instantiating a RCI_Locator package.
15980 (Build_From_Any_Function): To compute the High bound for an
15981 unconstrained array actual, we add the Low bound with the length.
15982 Thus we must convert the low bound and the length to an appropriate
15983 type before doing the sum.
15984 (Build_Subprogram_Receiving_Stubs, PolyORB):
15985 * Retrieve the extra formals parameters at the
15986 end of the parameter stream.
15987 * Use Move_Any_Value to write back out parameters
15988 after executing the request as it is more efficient
15989 than Copy_Any_Value.
15990 * Build the any containing Extra Formals with the
15991 appropriate typecode.
15992 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an

16006 function with the first not implicit parent type.
16007 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
16008 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
16009 typecode from the Etype. Therefore we retrieve the correct typecode
16010 with a call to Get_Any_Type.
16011 (Copy_Specification): Do controlling formal type substitution based on
16012 Is_Controlling_Formal flag, instead of caller-provided object type.
16013 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
16014 a RACW primitive operation, we might get a subprogram declaration for an
16015 ancestor of the RACW designated type (not for the designated type
16016 itself), in the case where this operation is inherited. In this case we
16017 have no easy means of determining the original tagged type for which
16018 the primitive was declared, so instead we now rely on
16019 Copy_Specification to use the Is_Controlling_Formal flag to determine
16020 which formals require type substitution.

16029 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
16030 run-time subprogram CW_Membership by call to Build_CW_Membership.
16031 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
16032 by a function call, a temporary must be created before expanding the
16033 Constructor_Call itself, to prevent out-of-order elaboration in the
16034 back-end when stack checking is enabled..
16036 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16038 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the

16163 standard 8bits encoding.
16164 (WS2SU): As above but converting from wide-sring to string.
16165 This is needed as it is necessary to have access to both versions in the
16166 runtime for the form parameter encoding support.
16167 This set of patch add support for the encoding form parameter.
16168 (S2WS): Improve implementation to handle cases where the filename is not
16169 UTF-8 encoded. In this case we default to using the current code page
16170 for the conversion.
16172 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
16173 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

16175 (fopen): Add encoding parameter.
16178 * s-ficobl.ads (AFCB): Add Encoding field to record the filename
16179 encoding. This is needed for the Reset routine (freopen low level-call).
16181 * s-fileio.adb (Open): Decode encoding form parameter and set the
16182 corresponding encoding value into AFCB structure.
16183 (Reset): Pass the encoding value to freopen.
16184 (Close): Move the call to Lock_Task to the beginning of the procedure.

16217 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16218 __gnat_adjust_context_for_raise.
16219 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16220 implementation of floating point operations as native x86 targets.
16221 So the FPU should be initialized in the same way using finit. Fix
16222 floating point operations accuracy issues.
16223 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
16224 member in struct sigaction, so as to avoid warning for incompatible

16240 Javier Miranda <miranda@adacore.com>
16242 * lib-xref.ads, lib-xref.adb:
16243 Modify the loop that collects type references, to include interface
16244 types that the type implements. List each of these interfaces when
16245 building the entry for the type.
16246 (Generate_Definition): Initialize component Def and Typ of new entry
16247 in table Xrefs, to avoid to have these components unitialized.
16248 (Output_References): Split Is_Abstract flag into
16249 Is_Abstract_Subprogram and Is_Abstract_Type.
16250 (Generate_Reference): Add barrier to do not generate the warning
16251 associated with Ada 2005 entities with entities generated by the

16293 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16294 it no longer destroys the contents of Name_Buffer or Name_Len and
16295 non-standard and invalid names are handled better.
16296 (Get_Decoded_Name_String): Improve performance by using
16297 Name_Has_No_Encodings flag in the name table.
16298 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
16299 Used for debugging printouts.

16302 Javier Miranda <miranda@adacore.com>
16303 Bob Duff <duff@adacore.com>
16305 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16306 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16307 there is no need to generate always a record_definition_node in case
16308 of synchronized interface types.
16309 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16310 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16311 illegal in Ada 95, in cases where it is legal. Change the warnings to
16312 errors in other cases. Don't give the error unless the "not null"
16313 parses properly. Correct the source position at which the error occurs.
16314 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16315 P_Null_Exclusion, to suppress "not null" warnings.

16367 Entry for pragma Unreferenced_Objects
16369 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
16370 switches, without repetition of "eD". Make sure that last character of
16371 -gnatep= switch is not taken as -gnat switch character.
16372 Complete rewrite of circuit for handling saving compilation options
16373 Occasioned by need to support dot switchs for -gnatw, but cleans up

16391 the default project path, initially done during elaboration of the
16393 If the prefix returned by Sdefault is null, get the prefix from a call
16394 to Executable_Prefix_Path.
16395 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16398 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16399 canonical directory name to open the directory from which files are
16401 (Record_Other_Sources): Idem.
16402 (Locate_Directory): Add the possibility to create automatically missing
16403 directories when Setup_Projects is True.

16406 library source copy dir and exec dir.
16408 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16411 2007-04-06 Robert Dewar <dewar@adacore.com>

16445 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
16446 full word is no longer compared twice.
16448 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16450 * sem_ch10.adb (Install_Limited_Context_Clauses.
16451 Expand_Limited_With_Clause): Use a new copy of selector name in the
16452 call to Make_With_Clause. This fixes the tree structure for ASIS
16453 purposes. Nothing is changed in the compiler behaviour.
16454 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16455 a package renaming.
16456 (Install_Limited_With_Clauses): Do not install non-limited view when it
16457 is still incomplete.
16459 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16460 Gary Dismukes <dismukes@adacore.com>
16462 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16463 when capturing size information, instead of base type, which for a
16464 formal array type will be the unconstrained type.
16465 (Analyze_Formal_Object_Declaration): Add check for illegal default
16466 expressions for a formal in object of a limited type.
16467 (Instantiate_Object): Ditto.
16468 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16469 because they were defaulted in the formal package and no check applies
16471 (Check_Formal_Package_Instance): Extend conformance check to other
16472 discrete types beyond Integer.
16473 (Process_Default): Copy directly the unmatched formal. A generic copy
16474 has already been performed in Analyze_Formal_Package.
16475 (Analyze_Associations): If a formal subprogram has no match, check for
16476 partial parametrization before looking for a default, to prevent
16478 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16479 not set the instantiation environment before analyzing the actuals.
16480 Fixes regression on 8515-003 with implementation of AI-133.
16481 Set_Instance_Env checks whether the generic unit is a predefined
16482 unit, in which case the instance must be analyzed with the latest Ada
16483 mode. This setting must take place after analysis of the actuals,
16484 because the actuals must be analyzed and frozen in the Ada mode extant
16485 outside of the current instantiation.
16486 (Save_Env, Restore_Env): Preserve and restore the configuration
16487 parameters so that predefined units can be compiled in the proper Ada
16489 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16490 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16491 and Is_Abstract_Type.
16492 (Analyze_Formal_Package): For better error recovery, Add exception
16493 handler to catch Instantion_Error, which can be raised in
16494 Analyze_Associations

16497 Bob Duff <duff@adacore.com>
16498 Gary Dismukes <dismukes@adacore.com>
16500 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16501 prefix type is a discriminated subtype of the type of the formal.
16502 (Analyze_Allocator): Collect all coextensions regardless of the context.
16503 Whether they can be allocated statically is determined in exp_ch4.
16504 (Analyze_Selected_Component): If the prefix is a limited view and the
16505 non-limited view is available, use the non-limited one.
16506 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16507 therefore illegal), suggest a qualified expression rather than a type
16508 conversion, because a type conversion would be illegal in this context.
16509 (Anayze_Allocator): Trace recursively all nested allocators so that all
16510 coextensions are on the corresponding list for the root. Do no mark
16511 coextensions if the root allocator is within a declaration for a stack-
16512 allocated object, because the access discriminants will be allocated on
16514 (Analyze_Call): Remove restriction on calls to limited functions for the
16515 cases of generic actuals for formal objects, defaults for formal objects
16516 and defaults for record components.
16517 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16518 element list. Their expansion is delayed until the enclosing allocator
16519 is processed and its finalization list constructed.
16520 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16521 for an operation with the given name among the primitive operations of
16522 the corresponding record type.
16523 (Analyze_Selected_Component): If the prefix is a task type that
16524 implements an interface, and there is no entry with the given name,
16525 check whether there is another primitive operation (e.g. a function)
16527 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16528 properly the indexing of a function call written in prefix form, where
16529 the function returns an array type, and all parameters of the function
16530 except the first have defaults.
16531 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16532 the original operands, rather than relocating them, for efficiency and
16533 to work properly when an operand is overloaded.
16534 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16535 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16536 (Analyze_Selected_Component): If the prefix is a private extension, only
16537 scan the visible components, not those of the full view.
16538 (Try_Primitive_Operation): If the operation is a procedure, collect all
16539 possible interpretations, as for a function, because in the presence of
16540 classwide parameters several primitive operations of the type can match
16541 the given arguments.
16543 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16544 Robert Dewar <dewar@adacore.com>
16546 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16547 tag-indeterminate call to an abstract function, when the left-hand side

16552 Thomas Quinot <quinot@adacore.com>
16554 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16555 out of Analyze_Package_Declaration, because processing must be applied
16556 to package bodies as well, for deferred constants completed by pragmas.
16557 (Analyze_Package_Declaration): When the package declaration being
16558 analyzed does not require an explicit body, call Check_Completion.
16559 (May_Need_Implicit_Body): An implicit body is required when a package
16560 spec contains the declaration of a remote access-to-classwide type.
16561 (Analyze_Package_Body): If the package contains RACWs, append the
16562 pending subprogram bodies generated by exp_dist at the end of the body.
16563 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16564 Is_Abstract_Subprogram and Is_Abstract_Type.
16565 (Preserve_Full_Attributes): The full entity list is not an attribute
16566 that must be preserved from full to partial view.
16568 * sem_dist.adb (Add_RAS_Dereference_TSS):
16569 Change primitive name to _Call so it cannot clash with any legal
16570 identifier, and be special-cased in Check_Completion.
16571 Mark the full view of the designated type for the RACW associated with
16572 a RAS as Comes_From_Source to get proper view switching when installing
16573 private declarations.
16574 Provite a placeholder nested package body along with the nested spec
16575 to have a place for Append_RACW_Bodies to generate the calling stubs
16576 and stream attributes.
16578 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16579 Robert Dewar <dewar@adacore.com>
16581 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16582 that is a limited view, check the non-limited view if available.
16583 (Undefined): Refine error message for missing with of Text_IO
16584 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16585 to distinguish real missing with cases.
16586 Fix format of all missing with messages
16587 (Analyze_Subprogram_Renaming): Emit proper error message on illegal

16607 object O, use the access level of O.
16608 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16609 rather than local Same_Formal_Type, to check whether protected operation
16610 overrides an inherited one.
16611 (Same_Formal_Type): New predicate, used when matching signatures of
16612 overriding synchronized operations, to handle the case when a formal
16613 has a type that is a generic actual.
16614 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16615 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.

16631 same result than Is_Ancestor.
16632 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16633 (Collect_Synchronized_Interfaces): Removed because the subprogram
16634 Collect_Abstract_Interfaces provides this functionality.

16636 concurrent types and thus avoid undesired code duplication.
16637 (Get_Subprogram_Entity): Handle entry calls.
16638 (May_Be_Lvalue): Include actuals that appear as in-out parameters in

16680 high bound is constant and the slice is empty. Tidy.
16681 (tree_transform, case N_Op_Not): Handle properly the case where the
16682 operation applies to a private type whose full view is a modular type.
16683 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16684 Address_Clause, use the associated Expression as the GNAT tree
16685 representing the choice value to ensure the corresponding GCC tree is
16686 of the proper kind.
16687 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16688 instead of just the operands, as the base GCC stabilize_reference does.
16689 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16690 requested; otherwise fail.
16691 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16696 implementation of UI_Div.
16697 (UI_Div): Reimplement as a call to UI_Div_Rem.

16951 (mainly static expression evaluation).
16952 Reword some continuation messages
16953 Add some \\ sequences to continuation messages
16954 (Resolve_Call): Refine infinite recursion case. The test has been

16968 during analysis, and use May_Be_Lvalue to distinguish read/write.
16969 (Valid_Array_Conversion): New procedure, abstracted from
16970 Valid_Conversion, to incorporate accessibility checks for arrays of
16971 anonymous access types.
16972 (Valid_Conversion): For a conversion to a numeric type occurring in an
16973 instance or inlined body, no need to check that the operand type is
16974 numeric, since this has been checked during analysis of the template.

17006 (Leap_Sec_Ops): New package in the private part of Ada.Calendar. This
17007 unit provides handling of leap seconds and is used by the new Ada 2005
17008 packages Ada.Calendar.Arithmetic and Ada.Calendar.Formatting.
17009 (Split_W_Offset): Identical spec to that of Ada.Calendar.Split. This
17010 version returns an extra value which is the offset to UTC.

17030 zone data and calculate the GMT offset.
17031 (__gnat_localtime_tzoff for Darwin, Free BSD, Linux, Lynx and Tru64):

17033 (__gnat_localtime_tzoff for AIX, HPUX, SGI Irix and Sun Solaris): Use
17034 the external variable "timezone" to calculate the GMT offset.

17486 formal parameters chaind list (set the Next_Entity of the last formal
17488 (Collect_All_Interfaces): Removed. This routine has been moved to
17489 sem_util and renamed as Collect_All_Abstract_Interfaces.
17490 (Set_All_DT_Position): Hidden entities associated with abstract
17491 interface primitives are not taken into account in the check for
17492 3.9.3(10); this check is done with the aliased entity.

17502 a primitive is not a predefined dispatching primitive but it is an
17503 alias of a predefined dispatching primitive.
17504 (Make_DT): If the ancestor of the type is a CPP_Class and we are
17505 compiling under full ABI compatibility mode we avoid the generation of
17506 calls to run-time services that fill the dispatch tables because under
17507 this mode we currently inherit the dispatch tables in the IP subprogram.
17508 (Write_DT): Emit an "is null" indication for a null procedure primitive.
17509 (Expand_Interface_Conversion): Use an address as the type of the formal
17510 of the internally built function that handles the case in which the

17545 where discriminants may be used for the bounds of entry families.
17546 (Apply_Address_Clause_Check): Remove side-effects if address expression
17547 is non-static and is not the name of a declared constant.

17559 rewritten replacement for Apply_Alignment_Check
17560 (Get_E_Length/Get_E_First_Or_Last): Add missing barrier to ensure that
17561 we request a discriminal value only in case of discriminants.
17562 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17563 assignments where the target subtype is unconstrained and the target
17564 object is a parameter or dereference (other aliased cases are known
17565 to be unconstrained).

17680 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17681 are build-in-place function calls.
17682 (Replace_Self_Reference): New subsidiary of
17683 Make_OK_Assignment_Statement, to replace an access attribute that is a
17684 self-reference into an access to the appropriate component of the
17685 target object. Generalizes previous mechanism to handle self-references
17686 nested at any level.
17687 (Is_Self_Referential_Init): Remove, not needed.
17688 (Is_Self_Referential_Init): New predicate to simplify handling of self
17689 referential components in record aggregates.

17692 (Has_Default_Init_Comps): Return True if a component association is a
17693 self-reference to the enclosing type, which can only come from a
17694 default initialization.
17695 (Make_OK_Assignment_Statement): If the expression is of the form
17696 Typ'Acc, where Acc is an access attribute, the expression comes from a
17697 default initialized self-referential component.
17698 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17699 that has been derived from several abstract interfaces we must also
17700 initialize the tags of the secondary dispatch tables.

17704 Javier Miranda <miranda@adacore.com>
17705 Robert Dewar <dewar@adacore.com>
17708 (Expand_Access_To_Protected_Op): If the context indicates that an access
17709 to a local operation may be transfered outside of the object, create an
17710 access to the wrapper operation that must be used in an external call.
17711 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17712 target, pass the Valid attribute applied to a floating-point prefix on
17713 to the back end without expansion.
17714 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17715 the allocated storage when it is specified by a per-object expression.
17716 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17717 Nothing to do here, the attribute has been rewritten during semantic

17726 into a fat pointer.
17727 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17728 subcomponent's enclosing variable is aliased with a constrained subtype.
17729 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17730 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17731 an aliased prefix must be known to be constrained in order to use True
17732 for the attribute value, and now it's possible for some aliased views
17733 to be unconstrained.
17735 2006-10-31 Robert Dewar <dewar@adacore.com>
17737 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17738 (Expand_Entity_Reference): Correct error of not handling subprogram
17739 formals in current_value processing.
17741 2006-10-31 Javier Miranda <miranda@adacore.com>

17746 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17747 register in the final list objects containing class-wide interfaces;
17748 otherwise we incorrectly register the tag of the interface in the final
17750 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17751 generate the wrapper if the parent primitive is abstract. This is
17752 required to report the correct error message.
17753 (Expand_N_Subtype_Indication): Do validity checks on range
17754 (Clean_Task_Names): If an initialization procedure includes a call to
17755 initialize a task (sub)component, indicate that the procedure will use
17756 the secondary stack.
17757 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17758 compatibility for interfacing with CPP by default.
17759 (Expand_N_Object_Declaration): Only build an Adjust call when the
17760 object's type is a nonlimited controlled type.
17761 * exp_ch3.adb: Add with and use of Exp_Ch6.
17762 (Expand_N_Object_Declaration): Check for object initialization that is a
17763 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17764 Object_Declaration to the call.
17765 (Freeze_Type): When the designated type of an RACW was not frozen at the
17766 point where the RACW was declared, validate the primitive operations
17767 with respect to E.2.2(14) when it finally is frozen.
17768 (Build_Initialization_Call,Expand_Record_Controller): Rename
17769 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17770 return-by-reference has no meaning in Ada 2005.
17771 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17772 to register tag of the immediate ancestor interfaces in the
17773 run-time structure.
17774 (Init_Secondary_Tags): Moved to the specification to allow the
17775 initialization of extension aggregates with abstract interfaces.
17776 (Build_Master_Renaming): Make public, for use by function declarations
17777 whose return type is an anonymous access type.
17778 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17779 Insert_List_Before_And_Analyze after the generation of the specs
17780 associated with null procedures.
17781 (Expand_Tagged_Root): Update documentation in its specification.
17782 (Init_Secondary_Tags): Update documentation.
17783 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17784 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17785 then generate code to inherit the contents of the dispatch table
17786 directly from the ancestor.
17787 (Expand_Record_Controller): Insert controller component after tags of
17788 implemented interfaces.
17789 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17790 create null procedure overridings when null procedures are inherited
17792 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17793 declarations for overriding null primitives inherited from interfaces.
17794 (Is_Null_Interface_Procedure): New function in
17795 Make_Null_Procedure_Specs.
17796 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17797 immediate ancestor of a tagged type is an abstract interface type we
17798 must generate the specification of the predefined primitives associated
17799 with controlled types (because the dispatch table of the ancestor is
17800 null and hence these entries cannot be inherited). This is required to
17801 elaborate well the dispatch table.

17815 the maximum for type T.
17816 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17817 when the allocator is initialized by a build-in-place call, since the
17818 allocator is already rewritten as a reference to the function result,
17819 and this prevents an unwanted duplication of the function call.
17820 Add with and use of Exp_Ch6.
17821 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17822 is a call to build-in-place function and apply
17823 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17824 untagged designated types).
17825 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17826 optimization if source or target is biased.
17827 (Expand_N_Allocator): Add comments for case of an allocator within a
17828 function that returns an anonymous access type designating tasks.
17829 (Expand_N_Allocator): apply discriminant checks for access

17840 (Expand_N_Assignment_Statement): Call
17841 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17842 build-in-place function call. Currently, this can happen only for
17843 assignments that come from aggregates.
17844 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17845 in order to alleviate the upward compatibility introduced by AI-318.
17846 (Expand_N_Extended_Return_Statement): Add support for handling the
17847 return object as a build-in-place result.
17848 (Expand_Non_Function_Return): Implement simple return statements nested
17849 within an extended return.
17850 (Enable_New_Return_Processing): Turn on the new processing of return
17852 (Expand_Non_Function_Return): For a return within an extended return,
17853 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17854 (Expand_N_Extended_Return_Statement): Implement AI-318
17855 (Expand_Simple_Function_Return): Ditto.
17856 (Expand_N_If_Statement): Handle new -gnatwt warning
17857 (Expand_N_Case_Statement): Handle new -gnatwt warning
17858 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17859 a protected object.
17860 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17861 validity checking of assignments to elementary record components.
17862 (Expand_N_Return_Statement): return Class Wide types on the secondary
17863 stack independantly of their controlled status since with HIE runtimes,
17864 class wide types are not potentially controlled anymore.
17866 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17869 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17870 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17871 it expects a block, procedure, or task. The return statement will get
17872 turned into a block, and Expand_Cleanup_Actions will happen then.

17875 Ed Schonberg <schonberg@adacore.com>
17876 Bob Duff <duff@adacore.com>
17877 Gary Dismukes <dismukes@adacore.com>
17879 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17881 (Expand_Inlined_Call): Tagged types are by-reference types, and
17882 therefore should be replaced by a renaming declaration in the expanded
17883 body, as is done for limited types.
17884 (Expand_Call): If this is a call to a function with dispatching access
17885 result, propagate tag from context.
17886 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17888 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17889 build-in-place when the right-hand side of an assignment is a
17890 build-in-place function call.
17891 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17892 of the explicit dereference of the allocator to the result subtype of
17893 the build-in-place function. This is needed to satisfy type checking
17894 in cases where the caller's return object is created by an allocator for
17895 a class-wide access type and the type named in the allocator is a
17897 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17898 conversion of the reference to the declared object to the result subtype
17899 of the build-in-place function. This is needed to satisfy type checking
17900 in cases where the declared object has a class-wide type. Also, in the
17901 class-wide case, change the type of the object entity to the specific
17902 result subtype of the function, to avoid passing a class-wide object
17903 without explicit initialization to the back end.
17904 (Register_Interface_DT_Entry): Moved outside the body of
17905 Freeze_Subprogram because this routine is now public; it is called from
17906 Check_Dispatching_Overriding to handle late overriding of abstract
17907 interface primitives.
17908 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17909 adding an implicit access actual on a call to a build-in-place function.

17912 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17913 (Is_Build_In_Place_Function): New function to determine whether an
17914 entity is a function whose calls should be handled as build-in-place.
17915 (Is_Build_In_Place_Function_Call): New function to determine whether an
17916 expression is a function call that should handled as build-in-place.
17917 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17918 calls to build-in-place functions as the initialization of an allocator.
17919 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17920 handling calls to build-in-place functions in contexts that do not
17921 involve init of a separate object (for example, actuals of subprogram
17923 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17924 handling calls to build-in-place functions as the initialization of an
17925 object declaration.
17926 (Detect_Infinite_Recursion): Add explicit parameter Process to
17927 instantiation of Traverse_Body to avoid unreferenced warning.
17928 (Check_Overriding_Inherited_Interfaces): Removed.

17932 inlined statements if within a transient scope.
17933 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17934 formal parameters with occurrences of actuals in inlined body, establish
17935 visibility on the proper view of the actual's subtype for the body's
17937 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17938 compatibility mode and we have an imported CPP subprogram because
17939 for now we assume that imported CPP primitives correspond with
17940 objects whose constructor is in the CPP side (and therefore we
17941 don't need to generate code to register them in the dispatch table).
17942 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17943 aligned selected component.
17944 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17945 the actual of an in-mode parameter is a type conversion.
17946 (Expand_Actuals): If the call does not come from source and the actual
17947 is potentially misaligned, let gigi handle it rather than rejecting the
17948 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17949 Class Wide types as returning by reference independantly of their
17950 controlled status since with HIE runtimes class wide types are not
17951 potentially controlled anymore.
17953 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17955 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity

17973 Pablo Oliveira <oliveira@adacore.com>
17975 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17976 subprogram Ids, even if they are not yet assigned.
17977 (Build_Subprogram_Id): It is now this function that will take care of
17978 calling Assign_Subprogram_Ids if necessary.
17979 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17980 should be done only once they are assigned.
17981 (Build_From_Any_Function, case of tagged types): Add missing call to
17983 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17984 type for an RACW type.
17985 (Add_RACW_Features): When processing an RACW declaration for which the
17986 designated type is already frozen, enforce E.2.2(14) rules immediately.
17987 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17988 special reordering of controlling formals.
17990 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17991 associated stub type for an RACW type.
17993 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17995 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17996 fixed-point operations in an integer context, i.e. as operands of a
17997 conversion to an integer type, indicate that result must be rounded.
17999 2006-10-31 Robert Dewar <dewar@adacore.com>
18001 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
18002 cases, pass the encoding method, since it is now required by the run
18005 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
18006 assumption that Str'First = 1.
18007 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
18008 it on to the Value_Wide_Wide_Character call.
18009 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
18010 properly handles a string of the form quote-encoded_wide_char-quote.
18012 * s-wchcnv.adb: Minor reformatting
18014 2006-10-31 Javier Miranda <miranda@adacore.com>
18016 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
18017 run-time membership test to ensure that the constructed object
18018 implements the target abstract interface.
18020 2006-10-31 Robert Dewar <dewar@adacore.com>
18022 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
18023 Machine_Attribute pragma internally to implement the user pragma.
18024 Add processing for pragma Interface so that it is now completely
18025 equivalent to pragma Import.
18027 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
18028 so that it can be applied to all entities, including record components
18029 and enumeration literals.
18030 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
18031 priority ranges are correct, verify compatibility against task
18032 dispatching and locking policies, and if everything is correct an entry
18033 is added to the table containing priority specific dispatching entries
18034 for this compilation unit.
18035 (Delay_Config_Pragma_Analyze): Delay processing
18036 Priority_Specific_Dispatching pragmas because when processing the
18037 pragma we need to access run-time data, such as the range of
18038 System.Any_Priority.
18039 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
18040 Allow pragma Unreferenced as a context item
18041 Add pragma Preelaborable_Initialization
18042 (Analyze_Pragma, case Interface): Interface is extended so that it is
18043 now syntactically and semantically equivalent to Import.
18044 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
18045 insertion characters.
18046 Add handling for Pragma_Wide_Character_Encoding
18047 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
18048 never supercedes a real restriction, and that a real restriction
18049 always supercedes a warning.
18050 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

18057 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
18058 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
18059 Is_Inherently_Limited_Type, because return-by-reference has no meaning
18061 (Find_Node_To_Be_Wrapped): Use new method of determining the result
18062 type of the function containing a return statement, because the
18063 Return_Type field was removed. We now use the Return_Applies_To field.
18065 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
18066 (Build_Task_Image_Decl): If procedure is not called from an
18067 initialization procedure, indicate that function that builds task name
18068 uses the sec. stack. Otherwise the enclosing initialization procedure
18069 will carry the indication.
18070 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
18071 N_Object_Declaration instead.
18072 (Kill_Dead_Code): New interface to implement -gnatwt warning for
18073 conditional dead code killed, and change implementation accordingly.
18074 (Insert_Actions): Add N_Return_Object_Declaration case.
18075 Correct comment to mention N_Extension_Aggregate node.
18076 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
18077 attempts to save information for global variables which cannot be
18079 (Get_Current_Value_Condition): Handle conditions the other way round
18080 (constant on left). Also handle right operand of AND and AND THEN
18081 (Set_Current_Value_Condition): Corresponding changes
18082 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
18083 (Get_Current_Value_Condition): Handle simple boolean operands
18084 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
18085 (Get_Current_Value_Condition): If the variable reference is within an
18086 if-statement, does not appear in the list of then_statments, and does
18087 not come from source, treat it as being at unknown location.
18088 (Get_Current_Value_Condition): Enhance to allow while statements to be
18089 processed as well as if statements.
18090 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
18092 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
18093 of loop. This is safe now that we fixed Kill_Current_Values.
18094 (OK_To_Do_Constant_Replacement): Check whether current scope is
18095 Standard, before examining outer scopes.
18097 2006-10-31 Vincent Celier <celier@adacore.com>
18099 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
18100 When True, apply VMS treatment to children of packages A, G, I and S.

18110 (Freeze_Entity): Add check for Preelaborable_Initialization
18112 * g-comlin.adb: Add Warnings (Off) to prevent new warning
18114 * g-expect.adb: Add Warnings (Off) to prevent new warning
18116 * lib-xref.adb: Add handling of Last_Assignment field
18117 (Generate_Reference): Centralize handling of pragma Obsolescent here
18118 (Generate_Reference): Accept an implicit reference generated for a
18119 default in an instance.
18120 (Generate_Reference): Accept a reference for a node that is not in the
18121 main unit, if it is the generic body corresponding to an subprogram
18124 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
18126 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
18128 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18130 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18131 use clauses, to avoid messages on packages used to qualify, and also
18132 to avoid messages from obsolescent units.
18133 (Warn_On_Useless_Assignments): Don't generate messages for imported
18134 and exported variables.
18135 (Warn_On_Useless_Assignments): New procedure

18143 2006-10-31 Olivier Hainque <hainque@adacore.com>
18145 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18146 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18148 2006-10-31 Bob Duff <duff@adacore.com>
18149 Robert Dewar <dewar@adacore.com>
18150 Ed Schonberg <schonberg@adacore.com>
18152 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18153 Ada 95 mode, because it violates the new rules for AI-318.
18155 * g-awk.ads: Use overloaded subprograms in every case where we used to
18156 have a default of Current_Session. This makes the code closer to be
18157 correct for both Ada 95 and 2005.
18159 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18160 code, relying on the fact that the compiler generates a warning
18161 instead of an error in -gnatg mode.
18163 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18164 E_Return_Statement entity kind.
18165 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18167 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18168 report an error if the reserved word abstract has been previously found.
18169 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18171 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18172 parenthesized range attribute usage
18173 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18175 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18176 in the syntax for extended_return_statement. This is not in the latest
18177 RM, but the ARG is expected to issue an AI allowing this.
18178 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18179 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18180 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18181 P_Return_Statement): Parse the new syntax for extended_return_statement.
18183 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18184 Output_End_Missing): Add error-recovery code for the new
18185 extended_return_statement syntax; that is, the new E_Return entry on
18188 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18189 limited to nonlimited, because otherwise we violate the new Ada 2005
18190 rules about returning limited types in function Create_AST_Handler in
18193 * sem.adb (Analyze): Add cases for new node kinds
18194 N_Extended_Return_Statement and N_Return_Object_Declaration.
18196 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18197 type is in the same category as type of context before applying check,
18198 to prevent anomalies in instantiations.
18199 (Resolve_Aggregate): Remove test for limited components in aggregates.
18200 It's unnecessary in Ada 95, because if it has limited components, then
18201 it must be limited. It's wrong in Ada 2005, because limited aggregates
18203 (Resolve_Record_Aggregate): Move check for limited types later, because
18204 OK_For_Limited_Init requires its argument to have been resolved.
18205 (Get_Value): When copying the component default expression for a
18206 defaulted association in an aggregate, use the sloc of the aggregate
18207 and not that of the original expression, to prevent spurious
18208 elaboration errors, when the expression includes function calls.
18209 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18210 were missing. We also didn't handle qualified expressions. Now also
18211 allow function calls. Use new common routine OK_For_Limited_Init.
18212 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18213 with space can upper case letter).
18215 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18216 Has_Static_Discriminants flag
18217 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18218 type with discriminants.

18220 (Build_Discriminant_Constraints): Use updated form of
18221 Denotes_Discriminant.
18222 (Process_Subtype): If the subtype is a private subtype whose full view
18223 is a concurrent subtype, introduce an itype reference to prevent scope
18225 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18226 Record_Type_Declaration): The functionality of the subprograms
18227 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18228 is now performed by a single routine.
18229 (Build_Derived_Record_Type): If the type definition includes an explicit
18230 indication of limitedness, then the type must be marked as limited here
18231 to ensure that any access discriminants will not be treated as having
18232 a local anonymous access type.
18233 (Check_Abstract_Overriding): Issue a detailed error message when an
18234 abstract subprogram was not overridden due to incorrect mode of its
18236 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18237 synchronized private extension declarations. Verify that the ancestor is
18238 a limited or synchronized interface or in the generic case, the ancestor
18239 is a tagged limited type or synchronized interface and all progenitors
18240 are either limited or synchronized interfaces.
18241 Derived_Type_Declaration): Check for presence of private extension when
18242 dealing with synchronized formal derived types.
18243 Process_Full_View): Enchance the check done on the usage of "limited" by
18244 testing whether the private view is synchronized.
18245 Verify that a synchronized private view is completed by a protected or
18247 (OK_For_Limited_Init_In_05): New function.
18248 (Analyze_Object_Declaration): Move check for limited types later,
18249 because OK_For_Limited_Init requires its argument to have been resolved.
18250 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18251 in order to alleviate the upward compatibility introduced by AI-318.
18252 (Constrain_Corresponding_Record): If the constraint is for a component
18253 subtype, mark the itype as frozen, to avoid out-of-scope references to
18254 discriminants in the back-end.
18255 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18256 this subprogram against wrong sources.
18257 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18258 discriminant of limited type completed with a protected type, when the
18259 discriminant is used to constrain a private component of the type, and
18260 expansion is disabled.
18261 (Find_Type_Of_Object): Do not treat a return subtype that is an
18262 anonymous subtype as a local_anonymous_type, because its accessibility
18263 level is the return type of the enclosing function.
18264 (Check_Initialization): In -gnatg mode, turn the error "cannot
18265 initialize entities of limited type" into a warning.
18266 (OK_For_Limited_Init): Return true for generated nodes, since it
18267 sometimes violates the legality rules.
18268 (Make_Incomplete_Declaration): If the type for which an incomplete
18269 declaration is created happens to be the currently visible entity,
18270 preserve the homonym chain when removing it from visibility.
18271 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18272 inherited subprograms.
18273 (Access_Definition): If this is an access to function that is the return
18274 type of an access_to_function definition, context is a type declaration
18275 and the scope of the anonymous type is the current one.
18276 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18277 incomplete subtype to the set of private dependents of the original
18279 (Constrain_Discriminated_Type): Emit an error message whenever an
18280 incomplete subtype is being constrained.
18281 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18282 corresponding subtype of the full view of the original incomplete type.
18283 (Check_Incomplete): Properly detect invalid usage of incomplete types
18286 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18288 * g-catiio.ads, g-catiio.adb (Value): New function.

18297 Robert Dewar <dewar@adacore.com>
18299 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18300 handling executable extension manually and duplicating code.
18302 * make.adb: Implement new -S switch
18303 (Gnatmake): Use new function Osint.Executable_Name instead
18304 of handling executable extension manually.
18306 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18307 is specified, the executable name ends with this suffix.
18308 Take advantage of Osint.Executable_Name instead of duplicating code.
18310 * switch-m.adb: Recognize new gnatmake -S switch
18312 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18314 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18317 * makeusg.adb: Add line for gnatmake -S switch
18319 2006-10-31 Vincent Celier <celier@adacore.com>
18321 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18322 call it with -static-libgcc, as there are some platforms, such as
18323 Darwin, where one of these two switches is compulsory to link.
18325 2006-10-31 Vincent Celier <celier@adacore.com>
18327 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18328 instead of ADA_PROJECT_PATH, for the project path.
18329 (Gnatls): When displaying the project path directories, use host dir
18332 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18333 names in the project path, as absolute paths may correspond to
18334 multi-valued VMS logical names.
18336 2006-10-31 Vincent Celier <celier@adacore.com>
18338 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18339 absolute path name.
18340 (Locate_Regular_File): Ditto
18341 (Change_Dir): Remove, no longer used
18342 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18343 on Windows. Get it calling Get_Current_Dir.
18344 (OpenVMS): Remove imported boolean, no longer needed.
18345 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18346 (Pid_To_Integer): New function to convert a Process_Id to Integer
18348 2006-10-31 Thomas Quinot <quinot@adacore.com>
18350 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18351 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18353 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18356 2006-10-31 Robert Dewar <dewar@adacore.com>

18365 2006-10-31 Robert Dewar <dewar@adacore.com>
18367 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18369 (Layout_Variant_Record): Retrieve the discriminants from the entity
18370 rather than from the type definition, because in the case of a full
18371 type for a private type we need to take the discriminants from the
18373 (Layout_Component_List): When applying the Max operator to variants with
18374 a nonstatic size, check whether either operand is static and scale that
18375 operand from bits to storage units before applying Max.
18376 (Layout_Type): In VMS, if a C-convention access type has no explicit
18377 size clause (and does not inherit one in the case of a derived type),
18378 then the size is reset to 32 from 64.
18380 2006-10-31 Vincent Celier <celier@adacore.com>
18382 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18383 its file has already been loaded, according to the unit being loaded,
18384 not to the current value of Multiple_Unit_Index.
18386 2006-10-31 Thomas Quinot <quinot@adacore.com>
18387 Eric Botcazou <ebotcazou@adacore.com>
18388 Arnaud Charlet <charlet@adacore.com>
18390 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
18391 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
18393 (a-except.o): Pass it to the compiler.
18394 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
18395 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
18396 a-calend-mingw.adb version.
18398 * Makefile.rtl: Added s-dsaser.
18399 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
18400 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
18401 Ada.Dispatching.Round_Robin.
18402 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
18404 * Make-lang.in: Remove all references to gt-ada-decl.h.
18405 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
18407 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
18408 Update dependencies.
18410 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
18412 2006-10-31 Vincent Celier <celier@adacore.com>
18414 * mlib-utl.adb (Initialized): Remove, no longer used
18415 (Initialize): Remove, no longer used
18416 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18417 if there is one, the archive indexer. Fail if the archive builder cannot
18419 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18422 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18424 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18425 Process_Body_Clauses): If the context of a body includes a use clause
18426 for P.Q then a with_clause for P in the same body is not redundant,
18427 even if the spec also has a with_clause on P.
18428 Add missing continuation mark to error msg
18429 (Build_Limited_Views): A limited view of a type is tagged if its
18430 declaration includes a record extension.
18431 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18432 node, even if the subunit has errors. This avoids malfunction by
18433 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18434 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18435 generation of obsolescent messages for with statements (cannot do
18436 this too early, or we cannot implement avoiding the messages in the
18437 case of obsolescent units withing obsolescent units).
18438 (Install_Siblings): If the with_clause is on a remote descendant of
18439 an ancestor of the current compilation unit, find whether there is
18440 a sibling child unit that is immediately visible.
18441 (Remove_Private_With_Clauses): New procedure, invoked after completing
18442 the analysis of the private part of a nested package, to remove from
18443 visibility the private with_clauses of the enclosing package
18445 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18446 now centralized in Generate_Reference.
18447 (Install_Limited_Context_Clauses): Remove superfluous error
18448 message associated with unlimited view visible through use
18449 and renamings. In addition, at the point in which the error
18450 is reported, we add the backslash to the text of the error
18451 to ensure that it is reported as a single error message.
18452 Use new // insertion for some continuation messages
18453 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18454 to create implicit with_clause for parent unit mentioned in original
18455 limited_with_clause.
18456 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18457 unit is a child unit. For ASIS queries.
18458 (Analyze_Subunit): If the subunit appears within a child unit, make all
18459 ancestor child units directly visible again.

18471 Add the new actual Abstract_Present to every call to
18472 P_Interface_Type_Definition.
18473 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
18474 a formal object declaration with an access definition or a subtype mark
18475 with a null exclusion.
18476 (P_Generic_Association): Handle association with box, and others_choice
18477 with box, to support Ada 2005 partially parametrized formal packages.
18479 2006-10-31 Robert Dewar <dewar@adacore.com>
18480 Javier Miranda <miranda@adacore.com>
18482 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18483 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18484 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18485 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18486 private extensions.
18487 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18488 to P_Interface_Type_Definition.
18489 (P_Interface_Type_Definition): Addition of one formal to report an error
18490 if the reserved word abstract has been previously found.
18491 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18492 object renaming declaration with an access definition or subtype mark
18493 with a possible null exclusion.
18495 * par-ch9.adb: Minor error msg fix
18497 * par-load.adb: Add missing continuation mark to error msg

18509 2006-10-31 Vincent Celier <celier@adacore.com>
18511 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
18512 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18515 2006-10-31 Vincent Celier <celier@adacore.com>
18517 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18518 on VMS, change "__" to '.' before checking the name.
18519 (Record_Ada_Source): Always add the source file name in the list of
18520 of sources, even if it is not the first time, as it is for another
18522 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18523 dot, instead of replacing only the first '_'.
18525 * prj-part.adb (Parse): Convert project file path to canonical form
18527 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18528 extended, the project id of the project extending it is recorded in its
18529 data, even when it has already been processed as an imported project.
18531 2006-10-31 Robert Dewar <dewar@adacore.com>
18533 * repinfo.adb (List_Entities): Don't list entities from renaming
18536 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18537 Robert Dewar <dewar@adacore.com>
18539 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18540 only a restriction warning is active for the given restriction. This is
18541 desirable because we do not want to modify code in the case where only
18543 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18544 causes overriding of real restrictions.
18545 Take advantage of new No_Restrictions constant.
18547 * raise.h: (__gnat_set_globals): Change profile.
18549 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18551 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18554 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18555 Move all the entities in obsolete package System.PolyORB_Interface to
18556 System.Partition_Interface.
18557 (RE_Storage_Size): New function in System.Tasking.

18570 Thomas Quinot <quinot@adacore.com>
18571 Javier Miranda <miranda@adacore.com>
18572 Gary Dismukes <dismukes@adacore.com>
18574 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18575 properly an attempt to apply Unchecked_Access to a protected operation.
18576 (OK_Self_Reference): New subprogram to check the legality of an access
18577 attribute whose prefix is the type of an enclosing aggregate.
18578 Generalizes previous mechanism to handle attribute references nested
18579 arbitrarily deep within the aggregate.
18580 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18581 can appear in an aggregate if this is a default-initialized aggregate
18582 for a self-referential type.
18583 (Resolve_Attribute, case Access): Ditto.
18584 Add support for new implementation defined attribute Stub_Type.
18585 (Eval_Attribute, case Attribute_Stub_Type): New case.
18586 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18587 (Stream_Attribute_Available): Implement using new subprogram from
18588 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18589 Has_Specified_Stream_Attribute flag.
18590 Disallow Storage_Size and Storage_Pool for access to subprogram
18591 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18592 access types of return subtypes in extended return statements. Remove
18593 accessibility checks on anonymous access types when Unchecked_Access is
18595 (Analyze_Attribute): Add support for the use of 'Class to convert
18596 a class-wide interface to a tagged type.
18597 Add support for the attribute Priority.
18598 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18599 whether the designated type is discriminated with a constrained partial
18600 view and require static matching in that case.
18601 Add local variable Des_Btyp. The Designated_Type
18602 of an access to incomplete subtype is either its non-limited view if
18603 coming from a limited with or its etype if regular incomplete subtype.
18605 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18606 Fix predicate to identify and allow cases of (expander-generated)
18607 references to tag of designated object of a RACW.
18608 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18609 non-static, and therefore cannot appear as a primary in a preelaborable
18611 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18612 Has_Read_Write_Attributes.
18613 (Has_Read_Write_Attributes): Reimplement in termes of
18614 Has_Stream_Attribute_Definition.
18615 (Missing_Read_Write_Attributes): When checking component types in a
18616 record, unconditionally call Missing_Read_Write_Attributes recursively
18617 (remove guard checking for Is_Record_Type / Is_Access_Type).
18619 2006-10-31 Robert Dewar <dewar@adacore.com>
18621 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18622 useless assignments here and conditionalize it on absence of exception
18624 (Analyze_Exception_Handlers): Small code reorganization of error
18625 detection code, for new handling of formal packages.
18627 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18628 Hristian Kirtchev <kirtchev@adacore.com>
18630 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18631 that has been constant-folded, preserve information of original tree,
18633 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18634 generated private extension declaration if the formal derived type is
18635 synchronized. Carry synchronized present over to the generated private
18637 (Validate_Derived_Type_Instance): Ensure that the actual of a
18638 synchronized formal derived type is a synchronized tagged type.
18639 (Instantiate_Formal_Package): When creating the instantiation used to
18640 validate the actual package of a formal declared without a box, check
18641 whether the formal itself depends on a prior actual.
18642 (Instantiate_Formal_Subprogram): Create new entities for the defining
18643 identifiers of the formals in the renaming declaration, for ASIS use.
18644 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18645 a renaming declaration or a subtype declaration for an actual in an
18646 instance, capture location information of declaration in generic, for
18648 (Instantiate_Formal_Package): Add comments on needed additional tests.
18649 AI-317 (partial parametrization) is fully implemented.
18650 (Validate_Private_Type_Instance): Add check for actual which
18651 must have preelaborable initialization
18652 Use new // insertion for some continuation messages
18653 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18654 Default_Expression. Add type retrieval when the declaration has an
18655 access definition. Update premature usage of incomplete type check.
18656 (Check_Access_Definition): New subsidiary routine. Check whether the
18657 current compilation version is Ada 05 and the supplied node has an
18659 (Instantiate object): Alphabetize local variables. Handle the creation
18660 of new renaming declarations with respect to the kind of definition
18661 used - either an access definition or a subtype mark. Guard against
18662 unnecessary error message in the context of anonymous access types after
18663 they have been resolved. Add check for required null exclusion in a
18664 formal object declaration.
18665 (Switch_View): A private subtype of a non-private type needs to be
18666 switched (the base type can have been switched without its private
18667 dependents because of the last branch of Check_Private_View.
18668 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18670 (Instantiate_Type): Emit an error message whenever a class-wide type of
18671 a tagged incomplete type is used as a generic actual.
18672 (Find_Actual_Type): Extend routine to handle a component type in a child
18673 unit that is imported from a formal package in a parent.
18674 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18675 agree on constrainedness, rather than checking against ultimate ancestor
18676 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18677 generic body, for navigation purposes.
18679 2006-10-31 Robert Dewar <dewar@adacore.com>
18680 Thomas Quinot <quinot@adacore.com>
18682 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18684 (New_Stream_Subprogram): When processing an attribute definition clause
18685 for a stream-oriented subprogram, record an entity node occurring at
18686 the point of clause to use for checking the visibility of the clause,
18687 as defined by 8.3(23) as amended by AI-195.
18688 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18689 New_Stream_Function and New_Stream_Procedure.
18690 (New_Stream_Function, New_Stream_Procedure): Removed.
18691 (Analyze_Attribute_Definition_Clause, case Address): Check new
18692 Alignment_Check check
18694 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18695 Javier Miranda <miranda@adacore.com>
18696 Robert Dewar <dewar@adacore.com>
18698 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18699 generate the same errors compiling under -gnatc.
18700 (Try_Object_Operation): If no candidate interpretation succeeds, but
18701 there is at least one primitive operation with the right name, report
18702 error in call rather than on a malformed selected component.
18703 (Analyze_Selected_Component): If the prefix is an incomplete type from
18704 a limited view, and the full view is available, use the full view to
18705 determine whether this is a prefixed call to a primitive operation.
18706 (Operator_Check): Verify that a candidate interpretation is a binary
18707 operation before checking the type of its second formal.
18708 (Analyze_Call): Add additional warnings for function call contexts not
18710 (Analyze_Allocator): Move the check for "initialization not allowed for
18711 limited types" after analyzing the expression. This is necessary,
18712 because OK_For_Limited_Init looks at the structure of the expression.
18713 Before analysis, we don't necessarily know what sort of expression it
18714 is. For example, we don't know whether F(X) is a function call or an
18715 indexed component; the former is legal in Ada 2005; the latter is not.
18716 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18717 were missing. We also didn't handle qualified expressions. Now also
18718 allow function calls. Use new common routine OK_For_Limited_Init.
18719 (Analyze_Type_Conversion): Do not perform some legality checks in an
18720 instance, because the error message will be redundant or spurious.
18721 (Analyze_Overloaded_Selected_Component): Do not do style check when
18722 setting an entity, since we do not know it is the right entity yet.
18723 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18724 (Analyze_Overloaded_Selected_Component): Same change
18725 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18726 since regular incomplete subtypes are transformed into corresponding
18727 subtypes of their full views.
18728 (Complete_Object_Operation): Treat name of transformed subprogram call
18729 as coming from source, for browsing purposes.
18730 (Try_Primitive_Operation): If formal is an access parameter, compare
18731 with base type of object to determine whether it is a primitive
18733 (Operator_Check): If no interpretation of the operator matches, check
18734 whether a use clause on any candidate might make the operation legal.
18735 (Try_Class_Wide_Operation): Check whether the first parameter is an
18736 access type whose designated type is class-wide.
18738 2006-10-31 Robert Dewar <dewar@adacore.com>
18739 Ed Schonberg <schonberg@adacore.com>
18740 Gary Dismukes <dismukes@adacore.com>

18743 warn on infinite loops.
18744 Add \\ to some continuation messages
18745 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18746 (Process_Bounds): If the bounds are integer literals that result from
18747 constant-folding, and they carry a user-defined type, preserve that type
18748 rather than treating this as an integer range.
18749 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18750 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18751 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18752 left hand side of assignment.
18753 (Analyze_Assignment): Add suport to manage assigments to the attribute
18754 priority of a protected object.
18755 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18756 not just identifiers.
18757 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18758 or AND THEN for possible tracking.
18759 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18760 case of while loops so we can track values in the loop body.
18762 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18763 Hristian Kirtchev <kirtchev@adacore.com>
18764 Bob Duff <duff@adacore.com>
18766 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18767 procedure cannot be a protected operation (it is a basic_declaration,
18768 not a subprogram_declaration).
18769 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18770 Subp. Add logic for entry processing.
18771 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18772 Determine whether an entry or subprogram of a protected or task type
18773 override an inherited primitive of an implemented interface.
18774 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18775 Update the actual used in calls to Check_Overriding_Indicator.
18776 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18777 generate the proper reference to the parent unit, for cross-reference.
18778 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18780 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18781 (Add_Extra_Formal): Revise procedure to allow passing in associated
18782 entity, scope, and name suffix, and handle setting of the new
18783 Extra_Formals field.
18784 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18785 pass new parameters. Add support for adding the new extra access formal
18786 for functions whose calls are treated as build-in-place.
18787 (Analyze_A_Return_Statement): Correct casing in error message.
18788 Move Pop_Scope to after Analyze_Function_Return, because an extended
18789 return statement really is a full-fledged scope. Otherwise, visibility
18790 doesn't work right. Correct use of "\" for continuation messages.
18791 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18792 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18793 the node doesn't get properly marked as analyzed.
18794 (Analyze_Subprogram_Body): If subprogram is a function that returns
18795 an anonymous access type that denotes a task, build a Master Entity
18797 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18798 proper usage of null exclusion in a result definition.
18799 (Process_Formals): Code cleanup and new error message.
18800 (Process_Formals): Detect incorrect application of null exclusion to
18802 (Conforming_Types): Handle conformance between [sub]types and itypes
18803 generated for entities that have null exclusions applied to them.
18804 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18805 base type is an access subtype. This case arrises with null exclusions.
18806 (New_Overloaded_Entity): Do not remove the overriden entity from the
18807 homonym chain if it corresponds with an abstract interface primitive.
18808 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18809 call to the synthesized predicate Is_Incomplete_Type.
18810 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18812 (Analyze_Subprogram_Declaration): Check that abstract interface
18813 primitives are abstract or null.
18814 (Analyze_Subprogram_Specification): Remove previous check for abstract
18815 interfaces because it was not complete.
18816 (Has_Interface_Formals): Removed.
18818 2006-10-31 Ed Schonberg <schonberg@adacore.com>

18821 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18822 of Analyze_Package_Body, to create Itype references for anonymous
18823 access types created in the package declaration, whose designated types
18824 may have only a limited view.
18825 (Analyze_Package_Specification): For the private part of a nested
18826 package, install private_with_clauses of enclosing compilation unit if
18827 we are in its visible part.
18828 (Declare_Inherited_Private_Subprograms): Complete barrier
18829 to ensure that the primitive operation has an alias to some parent
18830 primitive. This is now required because, after the changes done for the
18831 implementation of abstract interfaces, the contents of the list of
18832 primitives has entities whose alias attribute references entities of
18833 such list of primitives.
18834 (Analyze_Package_Specification): Simplify code that handles parent units
18835 of instances and formal packages.
18836 (Uninstall_Declarations): Check the convention consistency among
18837 primitive overriding operations of a tagged record type.

18851 as potentially use-visible.
18852 (Find_Type): Handle the case of an attribute reference for
18853 implementation defined attribute Stub_Type (simply let the analysis of
18854 the attribute reference rewrite it).

18856 type that appears in a Use_Type clause.
18857 (Analyze_Object_Renaming): Add support for renaming of the Priority

18866 Analyze_Subprogram_Renaming. Check whether the formals and return
18867 profile of a renamed subprogram have required null exclusions when
18868 their counterparts of the renaming already impose them.
18869 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18870 Determine whether an entity is inside a generic scope.
18871 (In_Open_Scope): First pass of documentation update.
18872 (Find_Expanded_Name): Add support for shadow entities associated with
18873 limited withed packages. This is required to handle nested packages.
18874 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18875 that makes a renaming of a limited withed package illegal.

18878 Ed Schonberg <schonberg@adacore.com>
18880 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18881 Check_Overriding_Indicator.
18882 (Analyze_Task_Definition): Ditto.
18883 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18884 (Check_Overriding_Indicator): To find overridden interface operation,
18885 examine only homonyms that have an explicit subprogram declaration, not
18886 inherited operations created by an unrelated type derivation.
18887 (Check_Overriding_Indicator): When checking for the presence of "null"
18888 in a procedure, ensure that the queried node is a procedure
18890 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18891 type when the formal is an access to variable.
18892 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18893 (Analyze_Task_Type): Same addition
18894 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to

18903 inherited from an interface ancestor by another interface in the
18904 context of an instance as 'late'.
18905 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18906 of a call to a function that dispatches on access result.
18907 (Check_Dispatching_Operation): In case of late overriding of a primitive
18908 that covers abstract interface subprograms we register it in all the
18909 secondary dispatch tables associated with abstract interfaces.
18910 (Check_Dispatching_Call): Add check that a dispatching call is not made
18911 to a function with a controlling result of a limited type. This is a
18912 current implementation restriction.
18913 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18914 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18915 argument is an interface type that is a generic formal.
18916 (Is_Interface_Subprogram): Removed.
18917 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18918 operation, check the formals to handle the case in which it is
18919 associated with an abstract interface type.

18936 Hristian Kirtchev <kirtchev@adacore.com>
18937 Javier Miranda <miranda@adacore.com>
18939 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18940 subprogram type to provide better diagnostics in case of ambiguity.
18941 (Covers): Handle coverage of formal and actual anonymous access types in
18942 the context of generic instantiation.
18943 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18944 abstract interface types; this is required to handle concurrent types
18945 with discriminants and abstract interface types.
18946 (Covers): Include type coverage of both regular incomplete subtypes and
18947 incomplete subtypes of incomplete type visibles through a limited with

18959 Add missing continuation marks in error msgs
18960 (Unqualify): New function for removing zero or more levels of
18961 qualification from an expression. There are numerous places where this
18962 ought to be used, but we currently only deal properly with zero or one
18964 (In_Instance); The analysis of the actuals in the instantiation of a
18965 child unit is not within an instantiation, even though the parent
18966 instance is on the scope stack.
18967 (Safe_To_Capture_Value): Exclude the case of variables that are
18969 (Check_Obsolescent): Removed
18970 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

18988 (Has_Compatible_Alignment): New function
18989 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
18990 objects to handle the Ada 2005 case, where aliasedness no longer implies

19048 (N_Extended_Return_Statement): New node for extended_return_statement
19050 (N_Return_Object_Declaration): New node for part of

19225 This is a significant redesign primarily for the sake of automatic
19226 timer task termination but also to fix a design flaw.
19227 Therefore we are now using an RTS lock, instead of a protected
19228 object, to provide mutual exclusion to the queue of pending events
19229 and the type Timing_Event is no longer a protected type.

20077 other basic tools. The full version that includes the Ada 2005 stuff

20079 not want to cause bootstrap problems with compilers not recognizing
20081 Add exception reason code PE_Implicit_Return

20375 Thomas Quinot <quinot@adacore.com>
20377 * checks.adb (Build_Discriminant_Checks): If the expression being
20378 checks is an aggregate retrieve the values of its discriminants to
20379 generate the check, rather than creating a temporary and a reference

20401 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
20402 Remove 0-9 as debug flag character possibilities
20403 -d is now controlling the primary stack size when its value is a
20404 positive. Also add checks against invalid values, and support for kb,
20405 mb. Ditto for -D switch.
20407 2006-02-13 Robert Dewar <dewar@adacore.com>
20408 Serguei Rybin <rybin@adacore.com>
20410 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
20411 save/restore routines.
20412 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20413 were not always properly handled previously.
20414 Since we are changing the tree format anyway, also get rid of the
20415 junk obsolete Immediate_Errors flag.
20416 (Tree_Read): Change the way of reading Tree_Version_String - now we
20417 read the version string from the tree even if its length is not the
20418 same as the length of the version string computed from Gnatvsn.
20419 (Search_Directory_Present): New Boolean flag for the compiler.
20420 Define Tree_Version_String as a dynamic string.

20439 corresponding full type declaration is missing and pragma CPP_Virtual
20441 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
20442 (Is_Known_Null): New flag

20445 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20446 explicitly declared limited.
20447 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20448 entities. Only used for component marked Is_Tag. If present it stores

20450 whose ancestor has discriminants.
20452 * exp_ch2.adb: Update status of new Is_Known_Null flag
20454 * sem_ch7.adb: Maintain status of new Is_Known_Null flag

20473 (__gl_default_stack_size): new variable.
20475 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20477 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20478 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20479 does not exist in the Ada RM.
20480 (Compatible_Int_Bounds): Determine whether two integer range bounds
20481 are of equal length and have the same start and end values.
20482 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20483 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20484 aggregate when it is part of an object declaration.
20485 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20486 constrains discriminants of its parent, add explicitly the discriminant
20487 constraints of the ancestor by retrieving them from the
20488 stored_constraint of the parent.
20490 2006-02-13 Robert Dewar <dewar@adacore.com>
20492 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20493 attribute Mechanism_Code is applied to renamed subprogram, modify
20494 prefix to point to base subprogram.
20495 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20497 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20498 renamed subprograms so that the front-end must replace the prefix
20501 2006-02-13 Javier Miranda <miranda@adacore.com>
20502 Gary Dismukes <dismukes@adacore.com>
20504 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20505 availability of RE_Interface_Tag.
20506 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20507 (Freeze_Record_Type): Do not generate the tables associated with
20508 timed and conditional dispatching calls through synchronized
20509 interfaces if compiling under No_Dispatching_Calls restriction.
20510 When compiling for Ada 2005, for a nonabstract
20511 type with a null extension, call Make_Controlling_Function_Wrappers
20512 and insert the wrapper function declarations and bodies (the latter
20513 being appended as freeze actions).
20514 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20515 predefined primitives associated with timed and conditional
20516 dispatching calls through synchronized interfaces if we are
20517 compiling under No_Dispatching_Calls.
20518 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20519 service is available before generating a call.
20520 (Make_Controlling_Function_Wrappers): New procedure.
20521 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20522 access-to-limited-interfaces because they can be used to reference
20523 tasks that implement such limited interface.
20524 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20525 procedure spec and body of the Offset_To_Top function that is generated
20526 when the parent of a type with discriminants has secondary dispatch
20528 (Init_Secondary_Tags): Handle the case in which the parent of the type
20529 containing secondary dispatch tables has discriminants to generate the
20530 correct arguments to call Set_Offset_To_Top.
20531 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20533 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20534 Add Wide_[Wide_]Expanded_Name.
20535 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20536 the same functionality of Get_Prim_Op_Address but applied to predefined
20537 primitive operations because the pointers to the predefined primitives
20538 are now saved in a separate table.
20539 (Parent_Size): Modified to get access to the separate table of primitive
20540 operations or the parent type.
20541 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20542 functionality of Set_Prim_Op_Address but applied to predefined primitive
20544 (Set_Signature): New subprogram used to store the signature of a DT.
20545 (Displace): If the Offset_To_Top value is not static then call the
20546 function generated by the expander to get such value; otherwise use
20547 the value stored in the table of interfaces.
20548 (Offset_To_Top): The type of the actual has been changed to Address to
20549 give the correct support to tagged types with discriminants. In this
20550 case this value is stored just immediately after the tag field.
20551 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20552 offset_to_top value is static and hence pass this value to the run-time
20553 to store it in the table of interfaces, or else if this value is dynamic
20554 and then pass to the run-time the address of a function that is
20555 generated by the expander to provide this value for each object of the
20558 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20559 (Default_Prim_Op_Count): New entity
20560 (Get_Predefined_Prim_Op_Address): New entity

20565 Ed Schonberg <schonberg@adacore.com>
20567 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20568 Make_Adjust_Call done for a newly-allocated object.
20570 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20571 in a subprogram are wrapped in a cleanup block, indicate that the
20572 subprogram contains an inner block with an exception handler.
20573 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20574 Adjust call is for a newly-allocated object. In that case we must not
20575 assume that the finalization list chain pointers are correct (since they
20576 come from a bit-for-bit copy of the original object's pointers) so if
20577 the attach level would otherwise be zero (no change), we set it to 4
20578 instead to cause the pointers to be reset to null.
20580 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20581 reset chain pointers to null.
20583 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20585 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20586 string, and the context requires a loop for the assignment (e.g.
20587 because the left-hand side is packed), generate a unique name for the
20588 temporary that holds the string, to prevent spurious name clashes.
20590 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20591 Javier Miranda <miranda@adacore.com>
20592 Robert Dewar <dewar@adacore.com>
20593 Gary Dismukes <dismukes@adacore.com>
20595 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20596 return unconstrained arrays.
20598 (Expand_Call): An indirect call through an access parameter of a
20599 protected operation is not a protected call.
20600 Add circuit to raise CE in Ada 2005 mode following call
20601 to Raise_Exception.
20602 (Register_DT_Entry): Do nothing if
20603 the run-time does not give support to abstract interfaces.
20604 (Freeze_Subprogram): In case of dispatching operations, do not generate
20605 code to register the operation in the dispatch table if the source
20606 is compiled with No_Dispatching_Calls.
20607 (Register_Predefined_DT_Entry): Generate code that calls the new
20608 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20609 Set_Prim_Op_Address.
20611 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20612 on array assignments if the right-hand side is a function call that has
20613 been inlined. Check is performed on the assignment in the block.
20614 (Process_Bounds): If bounds and range are overloaded, apply preference
20615 rule for root operations to disambiguate, and diagnose true ambiguity.
20616 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20617 a tag-indeterminate right-hand side even when Expander_Active is True.
20618 Needed to ensure that dispatching calls to T'Input are allowed and
20619 get the tag of the target class-wide object.
20621 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20622 an inherited primitive operation that already overrides several
20623 abstract interface primitives. For transitivity, the new entity must
20624 also override all the abstract interface primitives covered by the
20625 inherited overriden primitive.
20626 Emit warning if new entity differs from homograph in same scope only in
20627 that one has an access parameter and the other one has a parameter of
20628 a general access type with the same designated type, at the same
20629 position in the signature.
20630 (Make_Inequality_Operator): Use source locations of parameters and
20631 subtype marks from corresponding equality operator when creating the
20632 tree structure for the implicit declaration of "/=". This does not
20633 change anything in behaviour except that the decoration of the
20634 components of the subtree created for "/=" allows ASIS to get the
20635 string images of the corresponding identifiers.
20636 (Analyze_Return_Statement): Remove '!' in warning message.
20637 (Check_Statement_Sequence): Likewise.
20638 (Analyze_Subprogram_Body): For an access parameter whose designated type
20639 is an incomplete type imported through a limited_with clause, use the
20640 type of the corresponding formal in the body.
20641 (Check_Returns): Implicit return in No_Return procedure now raises
20642 Program_Error with a compile time warning, instead of beging illegal.
20643 (Has_Single_Return): Function returning unconstrained type cannot be
20644 inlined if expression in unique return statement is not an identifier.
20645 (Build_Body_To_Inline): It is possible to inline a function call that
20646 returns an unconstrained type if all return statements in the function
20647 return the same local variable. Subsidiary procedure Has_Single_Return
20648 verifies that the body conforms to this restriction.
20650 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20651 same type, and one of them is of an anonymous access type, convert
20652 the other operand to it, so that this is a valid binary operation for
20654 (Resolve_Type_Conversion): Handle subtypes of protected types and
20655 task types when accessing to the corresponding record type.
20656 (Resolve_Allocator): Add '\' in 2-line warning message.
20657 Remove '!' in warning message.
20658 (Resolve_Call): Add '\' in 2-line warning message.
20659 (Valid_Conversion): Likewise.
20660 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20661 resulting type may be an access type with an implicit dereference.
20662 Obtain the proper component from the designated type.
20663 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20664 given by an expanded name with prefix Standard, when the operands are
20665 of an anonymous access type.
20666 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20667 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20668 prefix of the expression is not of an incomplete type. Allows full
20669 diagnoses of all semantic errors.
20670 (Resolve_Actuals): If the actual is an allocator whose directly
20671 designated type is a class-wide interface we build an anonymous
20672 access type to use it as the type of the allocator. Later, when
20673 the subprogram call is expanded, if the interface has a secondary
20674 dispatch table the expander will add a type conversion to force
20675 the displacement of the pointer.
20676 (Resolve_Call): If a function that returns an unconstrained type is
20677 marked Inlined_Always and inlined, the call will be inlined and does
20678 not require the creation of a transient scope.
20679 (Check_Direct_Boolean_Op): Removed
20680 (Resolve_Comparison_Op): Remove call to above
20681 (Resolve_Equality_Op): Remove call to above
20682 (Resolve_Logical_Op): Inline above, since this is only call.
20683 (Valid_Conversion): Handle properly conversions between arrays of
20684 convertible anonymous access types.
20687 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20688 the literal in an unchecked conversion, because GCC 4.x needs a static
20689 value for a string bound.
20691 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20692 Hristian Kirtchev <kirtchev@adacore.com>
20694 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20695 components of the corresponding record, take into account component
20696 definitions that are access definitions.
20697 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20698 procedure is not considered a dispatching call and will be expanded
20701 2006-02-13 Javier Miranda <miranda@adacore.com>
20703 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20704 controlling argument of the dispatching call is an abstract interface
20705 class-wide type then we use it directly.
20706 Check No_Dispatching_Calls restriction.
20707 (Default_Prim_Op_Position): Remove the code that looks for the last
20708 entity in the list of aliased subprograms. This code was wrong in
20710 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20711 when the source is compiled with the No_Dispatching_Calls restriction.
20712 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20713 if we are compiling with restriction No_Dispatching_Calls.
20714 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20715 subprograms if we are compiling under No_Dispatching_Calls restriction.
20716 (Make_DT): Generate a dispatch table with a single dummy entry if
20717 we are compiling with the No_Dispatching_Calls restriction. In
20718 addition, in this case we don't generate code that calls to the
20719 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20720 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20721 of this subprogram if compiling with the No_Dispatching_Calls
20723 (Expand_Type_Conversion): Instead of using the actual parameter,
20724 the argument passed as parameter to the conversion function was
20725 erroneously referenced by the expander.
20726 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20727 Set_Predefined_Primitive_Op_Address and Set_Signature.
20728 (Expand_Dispatching_Call): Generate call to
20729 Get_Predefined_Prim_Op_Address for predefined primitives.
20730 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20731 predefined primitives.
20732 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20733 primitives we reserve one dummy entry to ensure that the tag does not
20734 point to some memory that is associated with some other object. In
20735 addition, remove all the old code that generated the assignments
20736 associated with the signature of the dispatch table and replace them
20737 by a call to the new subprogram Set_Signature.
20738 (Set_All_DT_Position): Change the algorithm because now we have a
20739 separate dispatch table associated with predefined primitive operations.
20740 (Expand_Interface_Conversion): In case of non-static offset_to_top
20741 add explicit dereference to get access to the object after the call
20742 to displace the pointer to the object.
20743 (Expand_Interface_Thunk): Modify the generation of the actual used
20744 in the calls to the run-time function Offset_To_Top to fulfil its
20746 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.

20750 * exp_dist.adb (Copy_Specification): For access parameters, copy
20751 Null_Exclusion flag, which will have been set for stream subprograms
20754 2006-02-13 Pascal Obry <obry@adacore.com>
20756 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20757 previous implementation was using the C runtime spawnve routine but
20758 the corresponding wait was using directly the Win32 API. This was
20759 causing some times a lock when waiting for an event using
20760 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20761 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20762 API fixes this problem.
20764 2006-02-13 Robert Dewar <dewar@adacore.com>
20766 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20774 array reference that is an explicit dereference, mark the converted
20775 (packed) array reference as analyzed to prevent a forthcoming
20776 reanalysis from resetting its type to the original (non-packed) array

20785 searching for the predefined equality operator, verify that operands
20786 have the same type.
20787 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20788 for the last entity in the list of aliased subprograms. This code
20789 was wrong in case of renamings.
20790 (Set_Renamed_Subprogram): New procedure
20791 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20792 Exp_Type constant computed when entering this subprogram.

20794 (OK_To_Do_Constant_Replacement): New function
20795 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20796 (Side_Effect_Free): An attribute reference 'Input is not free of
20797 side effect, unlike other attributes that are functions. (from code
20799 (Remove_Side_Effects): Expressions that involve packed arrays or records
20800 are copied at the point of reference, and therefore must be marked as
20801 renamings of objects.
20802 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20803 not a dispatching operation.
20806 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20807 elementary types in all cases.
20809 2006-02-13 Javier Miranda <miranda@adacore.com>

20812 task types when accessing to the corresponding record type.
20813 Remove '!' in warning message.
20815 2006-02-13 Olivier Hainque <hainque@adacore.com>
20817 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20818 to avoid useless and space inefficient overalignments on targets where
20819 Max_Alignment is larger than 16.
20821 2006-02-13 Pascal Obry <obry@adacore.com>
20823 * g-catiio.adb (Sec_Number): New type used to compute the number of
20824 seconds since 1-1-1970.
20825 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20826 negative numbers (years, months...) it is better to have a Natural here.
20828 (Image) [Number]: Change parameter from Long_Integer to Number.
20829 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20830 overflow for dates past year 2038.
20832 2006-02-13 Matthew Heaney <heaney@adacore.com>
20834 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20837 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20839 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20841 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20842 finalization can occur normally.
20844 2006-02-13 Vincent Celier <celier@adacore.com>
20846 * gnatcmd.adb (Rules_Switches): New table
20847 (Add_To_Rules_Switches): New procedure
20848 (GNATCmd): For command CHECK, put all options following "-rules" in the
20849 Rules_Switches table. Append these -rules switches after the -cargs
20852 2006-02-13 Robert Dewar <dewar@adacore.com>
20854 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20855 These two cases were generating incorrect output, and if this unit
20856 was built with checks on, generated a discriminant mismatch constraint
20859 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20860 Robert Dewar <dewar@adacore.com>
20862 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20863 view is an array type, indicate the component type as well, for
20864 navigation purposes.
20865 (Generate_Reference): Don't consider array ref on LHS to be a case
20866 of violating pragma Unreferenced.
20867 Do not give Ada 2005 warning except on real reference.
20869 2006-02-13 Vincent Celier <celier@adacore.com>
20871 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20872 main source, add switch -mdebug-main=_ada_ so that the executable can
20873 be debugged by the standard VMS debugger.
20874 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20875 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20876 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20877 of the last source, as the binding and linking phases are never
20879 Set all executable obsolete when rebuilding a library.
20881 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20884 2006-02-13 Javier Miranda <miranda@adacore.com>
20887 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20888 code to improve the error message reported when the program has
20889 declarations of abstract interface types and it is not compiled with
20890 the -gnat05 switch.
20891 (P_Access_Definition): Reorganize the code to improve the error
20892 message reported when the new Ada 2005 syntax for anonymous
20893 access types is used and the program is not compiled with the

20916 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20917 unknown, use the location of the project to report the error.
20918 (When_No_Sources): New global variable
20919 (Report_No_Ada_Sources): New procedure
20920 (Check): New parameter When_No_Sources. Set value of global variable
20922 (Find_Sources): Call Report_No_Ada_Sources when appropriate
20923 (Get_Sources_From_File): Ditto
20924 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20927 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20928 Call Prj.Proc.Process with parameter When_No_Sources.
20930 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20931 Call Recursive_Check with parameter When_No_Sources.
20932 (Recursive_Check): New parameter When_No_Sources. Call itself and
20933 Prj.Nmsc.Check with parameter When_No_Sources.
20934 (Process): New parameter When_No_Sources. Call Check with parameter
20936 (Copy_Package_Declarations): New procedure to copy renamed parameters
20937 and setting the location of the declared attributes to the location

20946 When removing nodes (attributes Source_Dirs, Source_Files,
20947 Source_List_File and package Naming), save the comments and attach the
20948 saved comments to the newly created nodes.
20949 Do not add a with clause for the naming package if one already exists.

20958 aliased entities to look for the overriden abstract interface
20960 (Is_Interface_Subprogram): Complete documentation.
20961 (Check_Dispatching_Operation): Do not generate code to register the
20962 operation in the dispatch table if the source is compiled with
20963 restriction No_Dispatching_Calls.

20965 No_Return procedure with procedure that is not No_Return
20966 (Check_Dispatching_Call): Suppress the check for an abstract operation
20967 when the original node of an actual is a tag-indeterminate attribute
20968 call, since the attribute, which must be 'Input, can never be abstract.
20969 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20970 call to the Input attribute (even when rewritten).
20971 (Propagate_Tag): Augment comment to indicate the possibility of a call
20972 to an Input attribute.
20974 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20975 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
20977 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.

20984 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20986 2006-02-13 Javier Miranda <miranda@adacore.com>
20988 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20989 handles default-initialized components to keep separate the management
20990 of this feature but also avoid the unrequired resolution and
20991 expansion of components that do not have partially initialized
20993 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20994 (Check_Bounds): Likewise.
20995 (Check_Length): Likewise.
20997 2006-02-13 Javier Miranda <miranda@adacore.com>
20998 Ed Schonberg <schonberg@adacore.com>
21000 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
21001 abstract interface type call analyze_and_resolve to expand the type
21002 conversion into the corresponding displacement of the
21003 reference to the base of the object.
21004 (Eval_Attribute, case Width): For systems where IEEE extended precision
21005 is supported, the maximum exponent occupies 4 decimal digits.
21006 (Accessibility_Message): Add '\' in 2-line warning message.
21007 (Resolve_Attribute): Likewise.
21008 (case Attribute_Access): Significantly revise checks
21009 for illegal access-to-subprogram Access attributes to properly enforce
21010 the rules of 3.10.2(32/2).
21011 Diagnose use of current instance with an illegal attribute.
21013 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
21015 (Enclosing_Generic_Unit): New function to return a node's innermost
21016 enclosing generic declaration node.
21017 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
21018 (Type_Access_Level): The accessibility level of anonymous acccess types
21019 associated with discriminants is that of the current instance of the
21020 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
21021 (Compile_Time_Constraint_Error): Handle case of conditional expression.
21022 (Kill_Current_Values_For_Entity): New function
21023 (Enter_Name): Change formal type to Entity_Id
21025 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
21026 Ed Schonberg <schonberg@adacore.com>
21027 Gary Dismukes <dismukes@adacore.com>
21029 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
21030 Analyze_Compilation_Unit.
21031 Detect and warn on redundant with clauses detected in a package spec
21032 and/or body when -gnatwr is used.

21034 (Install_Context_Items): Don't analyze config pragmas here
21035 (Install_Limited_Withed_Unit): Set limited entity of package in
21036 with_clause so that cross-reference information or warning messages on
21037 unused packages can be properly generated
21038 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
21039 has Error_Posted set. Prevent infinite loops in illegal programs.
21040 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
21041 to the point of the error test requiring the current unit to be private.
21042 This ensures that private with clauses are not exempted from the basic
21043 checking for being a descendant of the same library unit parent as a
21044 withed private descendant unit.
21045 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
21046 handle private with clauses properly, as well as to account for cases
21047 where the withed unit is a public descendant of a private ancestor
21048 (in which case the current unit must be a descendant of the private
21049 ancestor's parent). The spec comments were updated accordingly. Also,
21050 the old error message in this subprogram was replaced with error
21051 messages that mirror the errors tested and reported by
21052 Check_Private_Child_Unit.
21053 Parameter and variable names improved for readability.
21054 (Install_Limited_Context_Clauses): Remove test for a withed unit being
21055 private as the precondition for calling
21056 Check_Private_Limited_Withed_Unit since that subprogram has been
21057 revised to test public units as well as private units.

21064 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
21065 that Scope_Stack.First = 1.
21066 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21067 were not always properly handled previously.

21069 with multiple levels of parametrization by formal packages.
21070 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
21071 to the corresponding derived type declaration for proper semantics.
21073 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
21074 (Check_Component): Enforce restriction on components of
21075 unchecked_unions: a component in a variant cannot contain tasks or
21077 (Unchecked_Union): Allow nested variants and multiple discriminants, to
21079 Add pragma Ada_2005 (synonym for Ada_05)
21080 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21081 were not always properly handled previously.
21082 Document that pragma Propagate_Exceptions has no effect
21083 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
21084 (Set_Convention_From_Pragma): Check that if a convention is
21085 specified for a dispatching operation, then it must be
21086 consistent with the existing convention for the operation.
21087 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
21088 longer required to specify an vtable-ptr component in the record. For
21089 compatibility reasons we leave the support for the previous definition.
21090 (Analyze_Pragma, case No_Return): Allow multiple arguments
21092 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
21093 non-overrideen inherited operation with a controlling result as
21094 illegal only its implicit declaration comes from the derived type
21095 declaration of its result's type.
21096 (Check_Possible_Deferred_Completion): Relocate the object definition
21097 node of the subtype indication of a deferred constant completion rather
21098 than directly analyzing it. The analysis of the generated subtype will
21099 correctly decorate the GNAT tree.
21100 (Record_Type_Declaration): Check whether this is a declaration for a
21101 limited derived record before analyzing components.
21102 (Analyze_Component_Declaration): Diagnose record types not explicitly
21103 declared limited when a component has a limited type.
21104 (Build_Derived_Record_Type): Code reorganization to check if some of
21105 the inherited subprograms of a tagged type cover interface primitives.
21106 This check was missing in case of a full-type associated with a private
21108 (Constant_Redeclaration): Check that the subtypes of the partial and the
21109 full view of a constrained deferred constant statically match.
21110 (Mentions_T): A reference to the current type in an anonymous access
21111 component declaration must be an entity name.
21112 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
21113 class_wide type to refer to full type, not to the incomplete one.
21114 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
21115 available. Required to give support to the certified run-time.
21116 (Analyze_Component_Declaration): In case of anonymous access components
21117 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
21118 (Process_Discriminants): For an access discriminant, use the
21119 discriminant specification as the associated_node_for_itype, to
21120 simplify accessibility checks.
21122 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21123 Javier Miranda <miranda@adacore.com>
21125 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
21126 abstract interpretations on an operator, remove interpretations that
21127 yield Address or a type derived from it, if one of the operands is an
21129 (Try_Object_Operation.Try_Primitive_Operation,
21130 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
21131 location when creating the new reference to a primitive or class-wide
21132 operation as a part of rewriting a subprogram call.
21133 (Try_Primitive_Operations): If context requires a function, collect all
21134 interpretations after the first match, because there may be primitive
21135 operations of the same type with the same profile and different return
21136 types. From code reading.
21137 (Try_Primitive_Operation): Use the node kind to choose the proper
21138 operation when a function and a procedure have the same parameter
21140 (Complete_Object_Operation): If formal is an access parameter and prefix
21141 is an object, rewrite as an Access reference, to match signature of
21142 primitive operation.
21143 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21144 by an expanded name with prefix Standard, when the operands are of an
21145 anonymous access type.
21146 (Remove_Abstract_Operations): If the operation is abstract because it is
21147 inherited by a user-defined type derived from Address, remove it as
21148 well from the set of candidate interpretations of an overloaded node.
21149 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21152 2006-02-13 Bob Duff <duff@adacore.com>
21154 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21155 redundant use clauses.
21156 In particular, if the scope of two use clauses overlaps, but one is not
21157 entirely included in the other, we should not warn. This can happen
21158 with nested packages.
21159 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21160 reported errors. The bug was reported when the compiler was built
21161 with assertions enabled.
21162 (Find_Type): If the node is a 'Class reference and the prefix is a
21163 synchronized type without a corresponding record, return the type
21166 2006-02-13 Javier Miranda <miranda@adacore.com>
21168 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21169 if this is the full-declaration associated with a private declaration
21170 that implement interfaces, then the private type declaration must be
21172 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21173 as aliased. The use of the 'access attribute is not available for such
21174 object (for this purpose the object should be explicitly marked as
21175 aliased, but being an anonymous type this is not possible).
21177 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21178 Robert Dewar <dewar@adacore.com>
21180 * sem_elab.adb (Same_Elaboration_Scope): A package that is a

21190 (Add_One_Interp): Do not add to the list of interpretations aliased
21191 entities corresponding with an abstract interface type that is an
21192 immediate ancestor of a tagged type; otherwise we have a dummy
21193 conflict between this entity and the aliased entity.
21194 (Disambiguate): The predefined equality on universal_access is not
21195 usable if there is a user-defined equality with the proper signature,
21196 declared in the same declarative part as the designated type.
21197 (Find_Unique_Type): The universal_access equality operator defined under
21198 AI-230 does not cover pool specific access types.
21199 (Covers): If one of the types is a generic actual subtype, check whether
21200 it matches the partial view of the other type.
21202 2006-02-13 Thomas Quinot <quinot@adacore.com>
21204 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21205 line. This is necessary to allow In_Extended_Main_Unit to provide
21206 correct results for itypes while writing out expanded source.
21207 (Close_File): No need to update the source_index_table here since it's
21208 now done for each line.
21210 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21211 Robert Dewar <dewar@adacore.com>
21213 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21214 preserve the source unit where the itype is declared, and prevent a

21227 2006-02-13 Bob Duff <duff@adacore.com>
21229 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21230 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21231 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21232 raise Constraint_Error.
21234 * s-vallli.adb (Scan_Long_Long_Integer): Call
21235 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21236 do not scan leading blanks and sign twice.
21237 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21238 raise Constraint_Error.
21240 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21241 Scan_Long_Long_Unsigned): Split out most of the processing from
21242 Scan_Long_Long_Unsigned out into
21243 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21244 This prevents scanning leading blanks and sign twice.
21245 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21248 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21249 out most of the processing from Scan_Unsigned out into
21250 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21251 This prevents scanning leading blanks and sign twice.
21253 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21254 use with Modular'Value attribute.
21255 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
21258 2006-02-13 Robert Dewar <dewar@adacore.com>

21451 Florian Villoing <villoing@adacore.com>
21453 * a-taster.ads, a-taster.adb: New files.
21455 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21456 link to the version that does nothing. This way the task termination
21457 routine is not executed twice for the environment task when finishing
21458 because of an unhandled exception.
21460 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21461 handler because of an unhandled exception.
21463 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
21464 System.Tasking.Utilities instead of that in System.Tasking.Stages.
21466 * s-finimp.adb (initialization code): Modify the soft link for the
21467 finalization of the global list instead of Adafinal.
21469 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21470 non-tasking version of the soft link for task termination. We do
21471 nothing since if we are using the non-tasking version it
21472 means that the task termination functionality is not used.
21473 (Null_Finalize_Global_List): Add this null version for the procedure
21474 in charge of finalizing the global list for controlled objects.
21475 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21476 instead for handling run-time termination in a more flexible way.
21477 (Adafinal_NT): This new procedure will take care of finalizing the
21478 global list for controlled objects if needed, but no tasking
21481 * s-tarest.adb (Task_Lock): Do not try to lock again the
21482 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21483 some run-time operations.
21484 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21485 until all nested locks have been released.
21486 (Task_Wrapper): Call the fall-back task termination handler. It
21487 applies to all tasks but the environment task.
21488 (Finalize_Global_Tasks): Add the call for the task termination
21489 procedure for the environment task.
21490 (Task_Wrapper): suppress warnings around declaration of
21491 Secondary_Stack_Address.
21493 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21494 moved to the Common_ATCB record.
21495 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21496 Common_ATCB record.
21497 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21498 Common_ATCB record.
21500 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21501 Fall_Back_Handler, and Specific_Handler.
21503 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21504 defined in Ada.Task_Termination, to avoid circular dependencies.
21505 (Termination_Handler): Redefine this type here, alredy defined in
21506 Ada.Task_Termination, for avoiding circular dependencies.
21507 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21508 for storing task termination handlers. In addition,
21509 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21510 Common_ATCB because it is used by both the regular and the restricted
21512 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21513 Common_ATCB because it is used by both the regular and the restricted
21515 (Common_ATCB): Added a dynamic task analyzer field.
21517 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21518 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21519 (Task_Wrapper): Call the task termination handler. It applies to all
21520 tasks but the environment task.
21521 (Finalize_Global_Tasks): Call the task termination procedure for the
21522 environment task. The call to Finalize_Global_List is now performed
21523 using the soft links mechanism.
21524 (Task_Wrapper): added dynamic stack analysis.
21526 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21527 potentially blocking operations has been moved from
21528 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21529 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21530 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21531 this run-time check.
21533 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21534 of task termination procedure.
21535 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21536 link for the task termination procedure.
21538 * bindusg.adb: (Bindusg): Added documentation for -u option.

21551 * s-io.ads, s-io.adb (Standard_Error): new subprogram
21552 (Standart_Output): new subprogram
21553 (Set_Output): new subprogram
21554 (Put): now uses the value of Current_Out to know if the output has to be
21555 send to stderr or stdout.
21557 * s-stausa.ads: Complete implementation.
21559 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
21561 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
21562 list of Ada 05 files.
21563 (GNAT Library Units): Add AltiVec files.

21566 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
21567 g-alvety.ads, g-alvevi.ads: New files providing altivec API.

21572 file_name is empty.
21574 2005-12-09 Javier Miranda <miranda@adacore.com>
21575 Hristian Kirtchev <kirtchev@adacore.com>
21577 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21578 to the specification because the frontend generates code that uses this
21580 (Set_Interface_Table): Add missing assertion.
21581 Update documentation describing the run-time structure.
21582 (Displace): New subprogram that displaces the pointer to the object
21583 to reference one of its secondary dispatch tables.
21584 (IW_Membership): Modified to use the new table of interfaces.
21585 (Inherit_TSD): Modified to use the new table of interfaces.
21586 (Register_Interface_Tag): Use the additional formal to fill the
21587 contents of the new table of interfaces.
21588 (Set_Interface_Table): New subprogram that stores in the TSD the
21589 pointer to the table of interfaces.
21590 (Set_Offset_To_Top): Use the additional formal to save copy of
21591 the offset value in the table of interfaces.
21592 Update structure of GNAT Primary and Secondary dispatch table diagram.
21593 Add comment section on GNAT dispatch table prologue.
21594 (Offset_To_Signature): Update the constant value of the Signature field.
21595 (Dispatch_Table): Update comment on hidden fields in the prologue.

21598 the type of formal parameter T to Tag, introduce additional assertions.
21599 (Get_Num_Prim_Ops, Set_Num_Prim_Ops): Remove an unnecessary type
21601 (Get_Tagged_Kind, Set_Tagged_Kind): New bodies.
21603 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21604 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21605 record component containing the tag of the secondary dispatch table we
21606 have to use the Offset_To_Top run-time function to get this information;
21607 otherwise if the pointer to the base of the object has been displace
21608 we get a wrong value if we use the 'position attribute.
21610 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21611 all the calls to Expand_Interface_Thunk.
21612 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
21613 interfaces; hence the call to Set_Interface_Table was clearly wrong.
21614 (Collect_All_Interfaces): Modify the internal subprogram Collect to
21615 ensure that the interfaces implemented by the ancestors are placed
21616 at the header of the generated list.
21617 (Expand_Interface_Conversion): Handle the case in which the displacement
21618 associated with the interface conversion is not statically known. In
21619 this case we generate a call to the new run-time subprogram Displace.
21620 (Make_DT): Generate and fill the new table of interfaces.
21621 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21622 Get_Tagged_Kind and Set_Tagged_Kind.
21623 (Tagged_Kind): New function that determines the tagged kind of a type
21624 with respect to limitedness and concurrency and returns a reference to
21626 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
21627 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
21628 primary dispatch table for a type.
21629 (Make_DT, Make_Secondary_DT): Set the tagged kind in the primary and
21630 secondary dispatch table respectively of a tagged type.
21632 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
21633 (Expand_Interface_Conversion): New subprogram to indicate if the
21634 displacement of the type conversion is statically known.
21635 (DT_Access_Action): Add values Get_Tagged_Kind and Set_Tagged_Kind.
21637 * rtsfind.ads (RE_Offset_To_Top): New entity
21638 (RTU_Id): Add Ada_Task_Termination to the list so that it is made
21639 accessible to users.
21640 (Re_Displace): New entity
21641 (RE_Interface_Data): New entity
21642 (RE_Set_Interface_Data): New_Entity
21643 (RE_Id, RE_Unit_Table): Add entry for RE_Get_Tagged_Kind,
21644 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
21645 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
21646 RE_TK_Tagged, RE_TK_Task.
21648 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21649 Init_Secondary_Tags_Internal to allow its use with interface types and
21650 also to generate the code for the new additional actual required
21651 by Set_Offset_To_Top.
21652 (Build_Init_Statements): In case of components associated with abstract
21653 interface types there is no need to generate a call to its IP.
21654 (Freeze_Record_Type): Generate Select Specific Data tables only for
21656 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21657 the bodies and specifications of the predefined primitive operations
21658 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21659 for concurrent types.
21661 * exp_sel.ads, exp_sel.adb: New files.
21663 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21664 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21665 properly protected objects and attach handler in the case of the
21666 restricted profile.

21851 (Analyze_Component_Declaration): A limited component is
21852 legal within a protected type that implements an interface.
21853 (Collect_Interfaces): Do not add to the list the interfaces that
21854 are implemented by the ancestors.
21855 (Derived_Type_Declaration): If the parent of the full-view is an
21856 interface perform a transformation of the tree to ensure that it has
21857 the same parent than the partial-view. This simplifies the job of the
21858 expander in order to generate the correct object layout, and it is
21859 needed because the list of interfaces of the full-view can be given in
21861 (Process_Full_View): The parent of the full-view does not need to be
21862 a descendant of the parent of the partial view if both parents are

21939 available user-specified stream attributes on limited parameters to
21940 also test the type directly rather than only its underlying type (for
21941 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21942 attributes are visible at the point of the subprogram declaration.
21943 For Ada 2005, the error message is modified to indicate that the
21944 type's stream attributes must be visible (again, only for -gnat05).

21976 types use the corresponding record type. This was not needed before
21977 the implementation of Ada 2005 synchronized types because
21978 concurrent types were never tagged types in Ada 95.

22218 checks does not count in the first case, but does in the second).

22224 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
22225 elementary types using the operator in standard. It is cleaner not to
22226 modify the programmers intent, especially in the case of floating-point.

22230 subtype is an unconstrained packed type, convert the expression to its
22231 actual constrained subtype.

22252 Allow optional = after -gnatm
22253 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22254 longer sets Elaboration_Checks.
22255 Code to set warning mode moved to Sem_Warn
22256 so that it can be shared by pragma processing.
22258 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
22261 * s-taprop-solaris.adb:
22262 Change some <= to =, to avoid new warning

22270 * exp_vfpt.adb: Handle /= case
22271 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22278 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
22279 Increase default priority on Lynx from 15 to 17, and meet the Ada
22280 requirement that Default_Priority be ((Priority'First +

22383 we are not defining the type.
22384 <E_Record_Type>: Likewise.
22385 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22386 to get advantage of the new maybe_stabilize_reference interface, to
22387 ensure that what we reference is indeed stabilized instead of relying
22388 on assumptions on what the stabilizer does.
22389 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22390 type imported through a limited_with clause, use its non-limited view.
22391 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22393 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22394 of #if sections + explicit comparisons of convention identifiers.

22396 before early-returning for certain types when code generation is

22400 that we are not defining.
22401 (elaborate_expression_1): Do not create constants when creating
22402 variables needed by the debug info: the dwarf2 writer considers that
22403 CONST_DECLs is used only to represent enumeration constants, and emits
22405 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22406 object with an address clause into an indirect reference, drop the
22407 initializing expression.
22409 (STACK_CHECK_BUILTIN): Delete.
22410 (STACK_CHECK_PROBE_INTERVAL): Likewise.

22419 subtype to build an actual type with bounds template.
22420 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22421 is provided by the front-end, use that subtype to compute the size of
22422 the deallocated object.

22424 check for a potential violation of a No_Elaboration_Code restriction.

22429 maybe_stabilize, for common uses without restriction on lvalues and
22430 without need to check for the success indication.
22431 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22432 pass false instead of 0 as the FORCE argument which is a bool.
22433 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22434 attached to a renaming pointer has been properly stabilized, as no such
22435 object is attached otherwise.
22436 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22437 function uses the "target pointer" return mechanism.
22438 Reinstate conversion of the actual to the type of the formal
22439 parameter before any other specific treatment based on the passing

22449 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22450 static output of record constructor if all the components are constant.
22451 (gnat_build_constructor): For a record type, sort the list of field
22452 initializers in increasing bit position order.
22453 Factor common code to build a storage type for an unconstrained object
22454 from a fat or thin pointer type and a constrained object type.
22455 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22456 types variants, and process special cases of VIEW_CONVERT expressions
22457 as their NOP_EXPR counterpart to ensure we get to the
22458 CORRESPONDING_VARs associated with CONST_DECls.
22459 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22460 on the right-hand side.

22467 extracting the object if converting to a type variant.
22468 (create_var_decl): When a variable has an initializer requiring code
22469 generation and we are at the top level, check for a potential violation
22470 of a No_Elaboration_Code restriction.
22471 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22472 SIZE and SIZE_UNIT which we need for later back-annotations.

22474 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
22475 is an unchecked union.
22476 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22477 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22478 main variant, just replace the VIEW_CONVERT_EXPR.

22653 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
22654 and related): For a prefix that is an explicit dereference of an
22655 access to unconstrained packed array type, annotate the dereference
22656 with an actual subtype so GIGI can make a correct size computation.
22657 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22658 'Unrestricted_Access, if the designated type is an interface we
22659 add a type conversion to force the displacement of the pointer
22660 to the secondary dispatch table.
22661 Use Universal_Real instead of Long_Long_Float when we need a high
22662 precision float type for the generated code (prevents gratuitous
22663 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22664 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22665 'Terminated for task interface class-wide objects. Generate a call to

22695 (Expand_N_Return_Statement): When returning a mutable record, convert
22696 the return value into its actual subtype in order to help the backend
22697 to return the actual size instead of the maximum. This is another
22698 aftermath of not returning mutable records on the sec-stack anymore.

22990 scope against package Standard. Add comments and a ??? comment.
22991 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible

23012 full view to construct the full declaration of the derived type.
23013 (Build_Derived_Record_Type): Relax the condition that controls the
23014 execution of the check that verifies that the partial view and

23024 (Process_Full_View): Rename local subprogram Find_Interface_In_
23025 Descendant to Find_Ancestor_Interface to leave the code more clear.
23026 Remove wrong code that avoids the generation of an error message
23027 when the immediate ancestor of the partial view is an interface.
23028 In addition some minor reorganization of the code has been done to
23029 leave it more clear.
23030 (Analyze_Type_Declaration): If type has previous incomplete tagged
23031 partial view, inherit properly its primitive operations.
23032 (Collect_Interfaces): Make public, for analysis of formal

23045 be included in the interface list.
23046 (Access_Definition): If the designated type is an interface that may
23047 contain tasks, create Master_Id for it before analyzing the expression
23048 of the declaration, which may be an allocator.

23050 in allocators, the creation of master id's for task interfaces, etc.

23059 subprogram declaration.
23060 Change name Is_Package to Is_Package_Or_Generic_Package
23061 (Process_Formals): A non null qualifier on a non null named access
23062 type is not an error, and is a warning only if Redundant_Constructs

23066 Ed Schonberg <schonberg@adacore.com>
23068 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure

23070 declarations and use clauses within each of the parent units of a
23071 package instance of a generic child package.

23073 package associated with a generic instance or formal package, the
23074 private declarations of the parent must be installed (by calling new
23075 procedure Install_Parent_Private_Declarations).
23076 Change name Is_Package to Is_Package_Or_Generic_Package
23077 (Preserve_Full_Attributes): For a synchronized type, the corresponding

23083 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
23084 not try to rewrite a renamed stream attribute, because the operations
23085 on the type may not have been generated.
23086 Handle properly a renaming_as_body generated for a stream operation
23087 whose default is abstract because the object type itself is abstract.
23088 (Find_Type): If the type is incomplete and appears as the prefix of a
23089 'Class reference, it is tagged, and its list of primitive operations
23090 must be initialized properly.
23091 (Chain_Use_Clauses): When chaining the use clauses that appear in the
23092 private declaration of a parent unit, prior to compiling the private
23093 part of a child unit, find on the scope stack the proper parent entity
23094 on which to link the use clause.
23095 (Note_Redundant_Use): Emit a warning when a redundant use clause is
23097 (Analyze_Object_Renaming): An attribute reference is not a legal object

23118 remove address operations.

23132 after resolving operand, to avoid false warnings on overloaded calls.

23145 Change name In_Actual to In_Generic_Actual (clean up)

23851 (Build_Anonymous_Access_Type): Removed.
23852 (Expand_Interface_Actuals): With the previous cleanup there is no need
23853 to build an anonymous access type. This allows further cleanup in the
23854 code generated by the expander.
23855 (Expand_Interface_Conversion): If the actual is an access type then
23856 build an internal function to handle the displacement. If the actual
23857 is null this function returns null because no displacement is
23858 required; otherwise performs a type conversion that will be
23859 expanded in the code that returns the value of the displaced actual.
23860 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
23861 conversions that have no effect in the generated code because no
23862 displacement is required. Code cleanup; use local variables to
23863 avoid repeated calls to the subprogram directly_designated_type().

23872 (Expand_Subtype_From_Expr): Do not build actual subtype if the
23873 expression is limited.
23874 (Find_Interface_Tag): Add code to handle class-wide types and
23875 entities from the limited-view.
23877 * rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
23878 Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,

23903 Move with clauses outside Warnings Off now that dependent units are
23905 (Initialize): Call Interrupt_Managemeent.Initialize to ensure proper
23906 initialization of this unit.
23907 (Specific): Add new procedures Initialize and Delete so that this
23908 package can be used for VxWorks 5.x and 6.x
23909 (ATCB_Key, ATCB_Key_Address): Moved to Specific package body to hide
23910 differences between VxWorks 5.x and 6.x
23911 Minor reformatting.
23912 (Timed_Delay): Remove calls to Defer/Undefer_Abort, now performed by

23929 between Vxworks 5 and 6.
23930 (taskLock, taskUnlock): Removeed, no longer used.
23932 * adaint.c: The wait.h header is not located in the sys directory on
23933 VxWorks when using RTPs.
23934 (__gnat_set_env_value): Use setenv instead of putenv on VxWorks when
23936 (__gnat_dup): dup is available on Vxworks when using RTPs.
23937 (__gnat_dup2): dup2 is available on Vxworks when using RTPs.
23939 * cal.c: Use the header time.h for Vxworks 6.0 when using RTPs.
23941 * expect.c: The wait.h header is not located in the sys directory on
23942 VxWorks when using RTPs.

23961 set of constants that is consistent with the contents of g-soccon.ads.
23963 * gsocket.h: Code imported from gen-soccon.c:
23964 Move all target-specific file inclusions and macro definitions to
23965 gsocket.h, in order to ensure that any C code in socket.c will see a set
23966 of constants that is consistent with the contents of g-soccon.ads.
23967 This change also makes gen-soccon self-contained (removing dependencies
23968 upon GCC internal headers).
23970 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
23972 (To_Inet_Addr): Now a procedure instead of a function, more efficient.
23974 * socket.c: Minor reformatting.

24106 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
24107 from object notation, the original node is unanalyzed and carries no
24108 semantic information, so that accessiblity checks must be performed on
24109 the type of the actual itself.
24110 (Expand_N_Subprogram_Declaration): Change last actual parameter for
24111 compatibility with Build_Protected_Sub_Specification.

24122 load comes from a Limited_With_Clause.
24124 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
24125 whether a potential circularity is harmless, because it includes units
24126 loaded through a limited_with clause. Extends previous treatment which
24127 did not handle properly arbitrary combinations of limited and
24128 non-limited clauses.
24130 2005-09-01 Nicolas Setton <setton@adacore.com>
24132 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types

24165 position set is provided, we compute one in order to reduce the maximum
24166 length of the keys. This computation first selects a character
24167 position between 1 and the minimum length of the keys in order to
24168 avoid reducing one of the keys to an empty string.
24169 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24170 does not converge. The initialization procedure now comes with a
24171 maximum number of iterations such that when exceeded, an exception is
24172 raised in Compute. The user can initialize this ratio to another value
24174 Reformating and updated headers.

24178 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24179 that given an entity T creates and returns an Itype that duplicates the
24180 contents of T. The returned Itype has the null-exclusion
24181 attribute set to True, and its Etype attribute references T
24182 to keep the association between the two entities.
24183 Update copyright notice
24185 * sem_aggr.adb (Check_Can_Never_Be_Null,
24186 Aggregate_Constraint_Checks, Resolve_Aggregate,

24224 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
24225 syntax for anonymous access results.
24226 Replace Subtype_Mark field by Result_Definition in
24227 N_Function_Specification and N_Access_Definition specs.
24228 Add Null_Exclusion_Present to spec of N_Function_Specification.
24229 (Result_Definition): New function for N_Function_Specification and
24230 N_Access_Function_Definition.
24231 (Set_Result_Definition): New procedure for N_Function_Specification and
24232 N_Access_Function_Definition.
24234 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
24235 Result_Definition for cases of N_Access_Function_Definition and
24236 N_Function_Specification.
24237 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
24239 2005-09-01 Vincent Celier <celier@adacore.com>
24241 * lib-writ.adb: Update Copyright notice
24242 (Write_With_Lines): On platforms where file names are case-insensitive,
24243 record the file names in lower case.
24244 (Write_ALI): For D lines, on platforms where file names are
24245 case-insensitive, record the file names in lower case.
24247 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24248 Emmanuel Briot <briot@adacore.com>

24251 overridden operation.
24253 * lib-xref.ads: Add documentation on overridden operations.
24255 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
24258 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
24259 overriding entity information.

24264 including those that are inherited.
24266 2005-09-01 Robert Dewar <dewar@adacore.com>
24268 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
24270 * par-prag.adb: Implement new pragma Debug_Policy
24272 * sem_prag.adb Implement new pragma Debug_Policy
24273 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
24274 Component_Size attribute specification. Give warning for ignored pragma
24277 * snames.h, snames.ads, snames.adb: Introduce entries in
24278 Preset_Names for Name_Disp_Asynchronous_Select,
24279 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
24280 Name_Disp_Timed_Select.
24281 New pragma Debug_Policy
24283 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24285 Switch -gnata also sets Debug_Pragmas_Enabled
24287 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24288 handle an explicit -gnata when compiling predefined files.
24290 2005-09-01 Vincent Celier <celier@adacore.com>
24292 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24293 directories of projects that have no Ada sources.
24295 2005-09-01 Robert Dewar <dewar@adacore.com>
24297 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24298 (makes a difference for wide characters)
24300 * widechar.adb, widechar.ads:
24301 Add Wide_Char_Byte_Count feature to count chars vs bytes
24303 2005-09-01 Thomas Quinot <quinot@adacore.com>
24304 Ed Schonberg <schonberg@adacore.com>
24305 Robert Dewar <dewar@adacore.com>
24307 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24308 'Address attribute reference with an overloaded prefix, use the
24309 location of the prefix (not the location of the attribute reference) as
24310 the error location.
24311 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24312 a function renaming thereof, is a valid prefix for 'Size (where it is
24313 intepreted as a function call).
24314 (Statically_Denotes_Entity): New predicate to determine whether the
24315 prefix of an array attribute can be considered static.
24318 (Eval_Attr): Fix failure to evaluate Component_Size for
24319 unconstrained arrays (resulted in wrong value in packed case, since
24320 back end cannot handle this case)
24322 2005-09-01 Robert Dewar <dewar@adacore.com>
24324 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
24325 error msgs for most common cases.
24326 Use new errout insertion char < (conditional warning)
24328 2005-09-01 Javier Miranda <miranda@adacore.com>
24329 Ed Schonberg <schonberg@adacore.com>
24331 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24332 become local to the whole package.
24333 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24334 the package was already analyzed the new algorithm "replaces" the
24335 real entities by the shadow ones. This is required to ensure that
24336 the order of these entities in the homonym chains does not change;
24337 otherwise we can have undefined references at linking time because
24338 in case of conflicts the external name of the entities will have
24339 a suffix that depends on the order of the entities in the chain.
24340 (Remove_Limited_With_Clause): Complementary code that completes the
24341 new algorithm and replaces the shadow entities by the real ones.
24342 (Install_Limited_Withed_Unit): When unchaining entities before the
24343 installation of the shadow entities, only regular entities of the
24344 public part must be taken into account. This is required to
24345 keep this routine in synch with the work done by Remove_Limited_
24347 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24348 even if unit is analyzed, because the analysis of the unit is
24349 idempotent in any case, and the limited view of the unit may have to
24350 be installed for proper visibility.
24351 (Expand_Limited_With_Clause): Even if the unit in the implicit
24352 with_clause has been analyzed already, a limited view of the package
24353 must be built for the current context, if it does not exist yet.
24355 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24356 Javier Miranda <miranda@adacore.com>
24357 Gary Dismukes <dismukes@adacore.com>
24359 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24360 defining entity for the instance body, make a new defining identifier
24361 rather than copying the entity of the spec, to prevent accidental
24362 sharing of the entity list.
24363 (Check_Private_View): When exchanging views of private types, build the
24364 list of exchanged views as a stack, to ensure that on exit the exchanges
24365 are undone in the proper order.
24366 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24367 Restore the compilation environment in case of instantiation_error.
24368 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24369 for an anonymous access result.
24370 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24371 (Formal_Entity): Handle properly the case of a formal package that
24372 denotes a generic package renaming.
24374 2005-09-01 Thomas Quinot <quinot@adacore.com>
24376 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24377 clause if the array aggregate is surrounded by parentheses.
24379 2005-09-01 Cyrille Comar <comar@adacore.com>
24380 Gary Dismukes <dismukes@adacore.com>
24381 Ed Schonberg <schonberg@adacore.com>
24382 Javier Miranda <miranda@adacore.com>
24384 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24386 to check if a type is Constrained in cases related to code generation
24387 (rather than semantic checking) since otherwise we do not generate
24388 similar code for mutable private types depending if their
24389 discriminants are visible or not.
24390 (Check_Abstract_Overriding): Do not complain about failure to override
24391 the primitive operations used in dispatching selects since they will
24392 always be overriden at the freeze point of the type.
24393 (Access_Definition): Separate out handling for resetting the scope
24394 of an anonymous access function result type. Retrieve the scope
24395 of the associated function rather than using Current_Scope, which
24396 does not have a consistent value (depends on whether we're in the
24397 middle of analyzing formal parameters). Add ??? comment about
24398 finding a cleaner way to handle the special cases of scope setting.
24399 (Process_Incomplete_Dependents): A protected operation is never a
24400 dispatching operation (only its wrapper may be).
24401 (Build_Derived_Record_Type): In case of tagged private types that
24402 implement interfaces add derivation of predefined primitive
24404 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24405 by two parameters that are used in case of derivation from abstract
24406 interface types: No_Predefined_Prims is used to avoid the derivation
24407 of predefined primitives from the interface, and Predefined
24408 Prims_Only is used to complete the derivation predefined primitives
24409 in case of private tagged types implementing interfaces.
24410 Fix typo in comments
24411 (Find_Interface_In_Descendant): Protect the frontend against
24412 wrong code with large circularity chains.
24413 (Is_Private_Overriding): Add support for entities overriding interface
24414 subprograms. The test failed because Entities associated with overriden
24415 interface subprograms are always marked as hidden (and used to build
24416 the secondary dispatch table); in this case the overriden entity is
24417 available through the field abstract_interface_alias (cf. override_
24418 dispatching_operation)
24419 (Access_Definition): Set the scope of the type to Current_Scope for the
24420 case of a function with an anonymous access result type.
24421 (Access_Subprogram_Declaration): Handle creation of the type entity for
24422 an access-to-function type with an anonymous access result.
24423 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24424 in handling for N_Access_Function_Definition.
24425 (Analyze_Subtype_Declaration): Modify the text of error message.
24426 (Derived_Type_Declaration): Modify the text of error message.
24427 (Process_Subtype): Modify the text of error message plus cleanup
24428 of one redundant error message.
24429 (Analyze_Component_Declaration): Code cleanup.
24430 (Analyze_Object_Declaration): Code cleanup.
24431 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24432 attribute in case of access types. Code cleanup.
24433 (Array_Type_Declaration): Code cleanup.
24434 (Process_Discriminants): Create the new null-excluding itype
24435 if required. Code cleanup.
24436 (Process_Subtype): Create the new null-excluding itype if
24437 required. Code cleanup.
24438 (Build_Derived_Record_Type): Code cleanup to avoid calling
24439 twice the subprogram derive_subprograms in case of private
24440 types that implement interfaces. In this particular case the
24441 subprogram Complete_Subprograms_Derivation already does the
24442 job associated with the second call.
24444 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24445 conversion to the full view when generating an operation for a
24446 discriminant whose type may currently be private.
24448 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24449 Javier Miranda <miranda@adacore.com>
24451 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24452 V (Obj.F), the rewriting does not involve the indexed component, but
24453 only the selected component itself.
24454 Do not apply the transformation if the analyzed node is an actual of a
24455 call to another subprogram.
24456 (Complete_Object_Operation): Retain the entity of the
24457 dispatching operation in the selector of the rewritten node. The
24458 entity will be used in the expansion of dispatching selects.
24459 (Analyze_One_Call): Improve location of the error message associated
24461 (Analyze_Selected_Component): No need to resolve prefix when it is a
24462 function call, resolution is done when parent node is resolved, as
24464 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24465 when attempting to resolve a call transformed from its object notation.
24466 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24467 of the argument list for each interpretation of the operation.
24468 (Try_Object_Operation): The designated type of an access parameter may
24469 be an incomplete type obtained through a limited_with clause, in which
24470 case the primitive operations of the type are retrieved from its full
24472 (Analyze_Call): If this is an indirect call, and the return type of the
24473 access_to_subprogram is incomplete, use its full view if available.
24475 2005-09-01 Javier Miranda <miranda@adacore.com>
24476 Gary Dismukes <dismukes@adacore.com>
24478 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24479 access types the null-exclusion and access-to-constant attributes must
24481 (Analyze_Return_Statement): When the result type is an anonymous access
24482 type, apply a conversion of the return expression to the access type
24483 to ensure that appropriate accessibility checks are performed.
24484 (Analyze_Return_Type): For the case of an anonymous access result type,
24485 generate the Itype and set Is_Local_Anonymous_Access on the type.
24486 Add ??? placeholder for check to disallow returning a limited object
24487 in Ada 2005 unless it's an aggregate or a result of a function call.
24488 Change calls from Subtype_Mark to Result_Definition.
24489 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24490 Result_Definition in call to Make_Function_Specification.
24491 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24492 Set_Result_Definition.
24493 (Make_Inequality_Operator): Change formal Subtype_Mark to
24494 Result_Definition in call to Make_Function_Specification.
24495 (Process_Formals): Create the new null-excluding itype if required.
24496 (New_Overloaded_Entity): For an entity overriding an interface primitive
24497 check if the entity also covers other abstract subprograms in the same
24498 scope. This is required to handle the general case, that is, overriding
24499 other interface primitives and overriding abstract subprograms inherited
24500 from some abstract ancestor type.
24501 (New_Overloaded_Entity): For an overriding entity that comes from
24502 source, note the operation that it overrides.
24503 (Check_Conformance, Type_Conformant): Addition of one new formal
24504 to skip controlling formals in the analysis. This is used to
24505 handle overloading of abstract interfaces.
24506 (Base_Types_Match): Add missing case for types imported from
24507 limited-with clauses
24508 (New_Overloaded_Entity): Add barrier to protect the use of
24509 the "alias" attribute.
24511 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24513 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24514 verify that the procedure and the entry are mode conformant.
24515 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24516 as a different operator, which is often a cut-and-paste error.
24518 2005-09-01 Javier Miranda <miranda@adacore.com>
24519 Ed Schonberg <schonberg@adacore.com>
24521 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24522 used in controlling parameters exclude null because it is necessary to
24523 read the tag to dispatch, and null has no tag.
24524 (Override_Dispatching_Operation): If the previous operation is inherited
24525 from an interface, it becomes hidden and does not participate in later
24528 2005-09-01 Javier Miranda <miranda@adacore.com>
24529 Ed Schonberg <schonberg@adacore.com>
24530 Gary Dismukes <dismukes@adacore.com>
24532 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24533 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24534 the expander will generate the corresponding run-time check to evaluate
24536 (Resolve_Call): Check for legal type of procedure name or prefix that
24537 appears as a trigger in a triggering alternative.
24538 (Valid_Conversion): If expression is ambiguous and the context involves
24539 an extension of System, remove System.Address interpretations.
24540 (Resolve_Qualified_Expression): Reject the case of a specific-type
24541 qualification applied to a class-wide argument. Enhance comment
24542 to explain checking of Original_Node.
24543 (Resolve_Type_Conversion): The location of the error message was not
24544 general enough to handle the general case and hence it has been removed.
24545 In addition, this patch improves the text of the message.
24546 (Resolve_Type_Conversion): Add missing support for access to interface
24548 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24549 do not expand if the expression is the actual in a call, because proper
24550 expansion will take place when the call itself is expanded.
24551 (Resolve_Allocator): If the context is an unchecked conversion, the
24552 allocator inherits its storage pool, if any, from the target type of
24555 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24556 Javier Miranda <miranda@adacore.com>
24558 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24559 inherited interface operation that has an implementation, use the
24560 implementation to avoid spurious ambiguities.
24561 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24562 use the Corresponding_Record_Typ attribute to look for the interface
24563 because it is set by the expander (and hence it is not always
24564 available). For this reason we traverse the list of interfaces
24565 (available in the parent of the concurrent type).
24566 (Interface_Present_In_Ancestor): Handle entities from the limited view
24568 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24570 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24571 from the list of required components.
24572 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24573 primitive procedure of a limited interface with a controlling first
24575 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24577 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24578 capture if it is generated in the second operand of a short-circuit
24580 Do not capture values for variables with address clauses.
24581 (Is_Object_Reference): Treat a function call as an object reference only
24582 if its type is not Standard_Void_Type.
24584 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24586 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24587 to a variable that is statically known to be constant.

24599 Document that bounds of result of Base_Name match the input index
24601 Add documentation on environment variable syntax for Expand_Path
24603 * gnat_ugn.texi: Update documentation to include mention of -m switches
24604 Document new treatment of wide characters in max line length
24606 Remove -gnatL/-gnatZ switches, no longer used.
24607 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24610 * gnat_rm.texi: Add doc for two argument form of pragma
24611 Float_Representation.
24612 Add documentation for pragma No_Strict_Aliasing
24613 Add note that explicit component clause overrides pragma Pack.

25209 * s-mastop-irix.adb (Pop_Frame): Revert shorcuts avoiding calls to
25210 exc_unwind, now that we are generating proper .debug_frame output for
25213 * tracebak.c: Remove the mips-irix section, as we are now using the
25214 s-mastop based unwinder again.
25215 Under SPARC/Solaris, take into account the stack bias to compute the
25216 frame offset. The stack bias is 0 for the V8 ABI and 2047 for the V9

25369 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25370 longer protected objects. They have been replaced by lower-level
25371 suspension objects made up by a mutex and a condition variable (or
25372 their equivalent given a particular OS) plus some internal data to
25373 reflect the state of the suspension object.
25374 (Initialize, Finalize): Add this initialization procedure for
25375 Suspension_Object, which is a controlled type.
25376 (Finalize): Add the finalization procedure for Suspension_Object,
25377 which is a controlled type.
25379 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
25380 Ada.Synchronous_Task_Control because there is no longer a need for a
25381 VxWorks specific version of this package. Target dependencies
25382 has been moved to System.Task_Primitives.Operations.
25384 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
25386 (InitializeCriticalSection, EnterCriticalSection,
25387 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25388 pCriticalSection by an anonymous access type so that we avoid problems
25389 of accessibility to local objects.
25391 * s-taprop.ads, s-taprop-posix.adb, s-taprop-vxworks.adb,

25395 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
25396 set the environment task mask here.
25397 (Current_State): Add this function that returns the state of the
25399 (Set_False): Add this procedure that sets the state of the suspension
25401 (Set_True): Add this procedure that sets the state of the suspension
25402 object to True, releasing the task that was suspended, if any.
25403 (Suspend_Until_True): Add this procedure that blocks the calling task
25404 until the state of the object is True. Program_Error is raised if
25405 another task is already waiting on that suspension object.
25406 (Initialize): Add this procedure for initializing the suspension
25407 object. It initializes the mutex and the condition variable which are
25408 used for synchronization and queuing, and it sets the internal state
25410 (Finalize): Add this procedure for finalizing the suspension object,
25411 destroying the mutex and the condition variable.

25416 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
25417 which provides a low-level abstraction (using operating system
25418 primitives) for Ada.Synchronous_Task_Control.
25419 This object is made up by a mutex (for ensuring mutual exclusion), a
25420 condition variable (for queuing threads until the condition is
25421 signaled), a Boolean (State) indicating whether the object is open,
25422 and a Boolean (Waiting) reflecting whether there is a task already
25423 suspended on this object.

25430 * s-inmaop-posix.adb, s-inmaop-vms.adb, s-inmaop-dummy.adb,
25431 (Setup_Interrupt_Mask): New procedure.
25433 * s-intman-vxworks.ads, s-intman-vxworks.adb: Update comments.
25435 * s-inmaop.ads (Setup_Interrupt_Mask): New procedure
25437 * s-interr.adb: Add explicit call to Setup_Interrupt_Mask now that
25438 this is no longer done in the body of s-taprop
25439 (Server_Task): Explicitely test for Pending_Action in case
25440 System.Parameters.No_Abort is True.
25442 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
25443 is no longer done in the body of s-taprop

25616 * exp_ch5.adb (Expand_N_Return_Statement): When a function's result
25617 type is a class-wide type, emit a run-time check that the accessibility

25688 type derivation of private tagged types implementing interfaces.
25689 In this case some interface primitives may have been overriden

25779 * i-cpp.ads, i-cpp.adb:
25780 This package has been left available for compatibility with previous
25781 versions of the frontend. As part of the new layout this is now a

25819 on subprogram stubs as well.
25820 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
25822 (Analize_Subprogram_Specification): When analyzing a subprogram in which

25825 (Analyze_Subprogram_Body): Undo the previous work.
25826 (Analyze_Procedure_Call): If the call has the form Object.Op, the

25835 access to subprograms must be recursive.
25836 (Is_Unchecked_Conversion): Improve the test that recognizes
25837 instantiations of Unchecked_Conversion, and allows them in bodies that
25838 are to be inlined by the front-end. When the body comes from an
25839 instantiation, a reference to Unchecked_Conversion will be an
25840 Expanded_Name, even though the body has not been analyzed yet.

25859 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
25860 in the case where the target type is an anonymous access type of an
25861 object or component (that is, when Is_Local_Anonymous_Access is true).
25862 Prevent the special checks for conversions of access discriminants in
25863 the case where the discriminant belongs to a nonlimited type, since
25864 such discriminants have their accessibility level defined in the same
25865 way as a normal component of an anonymous access type.
25866 (Resolve_Allocator): When an allocator's designated type is a class-wide
25867 type, check that the accessibility level of type given in the
25868 allocator's expression or subtype indication is not statically deeper
25869 than the level of the allocator's access type.

25883 weakened in Ada 2005.
25884 Call to obsolescent subprogram is now considered to be a violation of
25885 pragma Restrictions (No_Obsolescent_Features).
25886 (Check_Direct_Boolean_Operator): If the boolean operation has been
25887 constant-folded, there is nothing to check.
25888 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25889 check on possible violation of restriction No_Direct_Boolean_Operators

26311 Add information about generic parent for package and subprogram
26313 (Get_Type_Reference): For a subtype that is the renaming of an actual in
26314 an instantiation, use the first_subtype to ensure that we don't generate
26315 cross-reference information for internal types.

26346 different contents.
26347 (__gnat_adjust_context_for_raise) i386-linux: First version of this
26348 function for this target. Adjust PC by one in the machine context. This
26349 adjustment was previously done in the MD_FALLBACK_FRAME_STATE_FOR, but

26353 prior to the raise.
26354 (__gnat_error_handler) i386-linux: Adjust the signature to match what a
26355 SA_SIGINFO sigaction should look like. Call

26847 (check dos line terminator).
26848 (Check_Line_Max_Length): New procedure, split off from the existing
26849 Check_Line_Terminator routine. Separating this out allows -gnatyf to
26850 be properly recognized.
26852 * styleg.adb: Add ??? comment for line terminator reference
26854 * scng.adb (Check_End_Of_Line): Fix bug of -gnatyf being ignored

26895 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26896 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26897 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26898 analyzed if expansion is disabled (which could otherwise cause spurious
26899 error messages if expansion has been disabled due to previous
26900 (unrelated) errors).
26902 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26903 is disabled, the entity denoted by the argument is the access type
26904 itself, not an underlying record type, so there is no need to go back
26905 to the Corresponding_Remote_Type.
26907 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26908 Robert Dewar <dewar@adacore.com>
26910 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
26911 expand a call to an instance of
26912 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the

26914 check is also generated, to ensure that the tag passed to the instance
26915 denotes a type in the class.
26916 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26917 of Name_Generic_Dispatching_Constructor.
26919 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

26935 generic formal subprogram association for an abstract formal subprogram.
26936 Check that the attribute is a primitive stream attribute (and not
26937 a class-wide stream attribute) and then rewrite the attribute name
26938 as the name of the appropriate compiler-generated stream primitive.

26950 itype whose parent is controlled and not yet frozen, do not create a
26951 freeze node for the itype if expansion is disabled.
26953 2005-03-29 Vincent Celier <celier@adacore.com>
26955 * make.adb (Gnatmake): Don't fail if the main project file is declared
26956 as having no Ada sources. Do not display message "no sources to
26957 compile" in quiet output.

26977 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26978 rather than proceed ahead using a junk attribute name.
26980 2005-03-29 Vincent Celier <celier@adacore.com>
26982 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26984 * prj-part.adb (Parse_Single_Project): Set the location of a project
26985 on its defining identifier, rather than on the reserved word "project".
26987 * prj-proc.adb (Expression): Adapt to the fact that default of external
26988 references may be string expressions, not always literal strings.
26989 (Recursive_Process): Set Display_Name equal to Name
26990 when Location is No_Location, that is when there is no actual file.
26991 Get the Display_Name of the project from the source, when it is not a
26993 (Process): Use the Display_Name in error messages
26995 * prj-strt.adb (External_Reference): Allow default to be string
26996 expressions, not only literal strings.
26998 2005-03-29 Vincent Celier <celier@adacore.com>

27006 forbid conversion of a local access-to-subprogram type to a remote one.
27008 * sem_util.adb (Wrong_Type): For a record type that is the expanded
27009 equivalent type for a remote access-to-subprogram type, go back to the
27010 original RAS entity when displaying an error message, so the casing is
27011 the original source casing.

27015 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
27018 2005-03-29 Ed Schonberg <schonberg@adacore.com>
27020 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
27021 subtype if code is being pre-analyzed, to prevent un-expanded
27022 references to protected formals, among others.
27023 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
27024 interpretation that can be a call, include the result of the call as a
27025 possible interpretation of the dereference.
27027 * sem_ch5.adb (Process_Bounds): Determine type of range by
27028 pre-analyzing a copy of the original range, and then analyze the range
27029 with the expected type.
27031 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
27032 with an overloaded prefix where not all interpretations yield an
27033 access to subprogram, do not rewrite node as a call.
27034 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
27035 the node as a call once the context identifies the interpretation of
27036 the prefix whose call yields the context type.
27037 (Valid_Conversion): For the case of a conversion between
27038 local access-to-subprogram types, check subtype conformance using
27039 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
27040 detailed error message.

27044 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
27045 indicator, indicate that the formal can never be null.
27046 (Process_Formals): If a formal has a non_null indicator, insert the
27047 resulting subtype immediately before the enclosing subprogram decl,
27048 and not at the beginning of the corresponding declarative part, to
27049 prevent access before elaboration (Ada2005).

27173 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
27174 subprogram determines whether a default implementation exists for a
27175 given stream attribute.
27176 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
27177 Determine whether to generate a default implementation for each stream
27178 attribute separately, as this depends on the specific attribute.
27180 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
27181 limited extension where a stream attribute is missing for a limited
27182 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

27666 tables (rather than a single dispatch table).
27667 Similarly, upgrade all the references to Tag_Component by the
27668 new attribute First_Tag_Component.

27716 Task_Body_Procedure has been moved to the corresponding task type
27717 or task subtype entity to leave a field free to store the list
27718 of interfaces implemented by a task (for AI-345)

27783 expression to the type of the object when the object is constant.
27784 Reverse defer_debug_incomplete_list before traversing it, so that trees
27785 are processed in the order at which they were added to the list. This
27786 order is important when using the stabs debug format.
27787 If we are deferring the output of debug information, also defer this
27788 output for a function return type.

27810 write_record_type_debug_info.
27811 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27812 (update_pointer_to): Fix pasto.
27813 (convert) <UNION_TYPE>: Accept slight type variations when
27814 converting to an unchecked union type.
27816 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27817 replace the N_Freeze_Entity with a null statement.
27819 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27820 within a constrained subcomponent of an enclosing record, place the
27821 freeze nodes in the scope stack entry for the enclosing record.
27822 (Undelay_Type): New Subprogram.
27823 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27824 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27825 within records; allow them to have freeze nodes if their base types
27828 * exp_util.adb (Remove_Side_Effects): Properly test for
27829 Expansion_Delayed and handle case when it's inside an
27830 N_Qualified_Expression.
27832 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27833 Comes_From_Generic, to recognize accurately that the parent type in a
27834 derived type declaration can be traced back to a formal type, because
27835 it is one or is derived from one, or because its completion is derived
27837 (Constrain_Component_Type): If component comes from source and has no
27838 explicit constraint, no need to constrain in in a subtype of the
27840 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27841 Minor change to propagate Is_Ada_2005 flag
27843 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27844 Expansion_Delayed is False.
27845 (assoc_to_constructor): Ignore fields that have a
27846 Corresponding_Discriminant.
27847 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27848 function returns "by target", dereference the target pointer using the
27849 type of the actual return value.
27850 <all>: Be prepared for a null gnu_result.
27851 (processed_inline_subprograms): Check flag_really_no_inline
27852 instead of flag_no_inline.
27853 (set_second_error_entity): Remove unused function.

27858 2005-03-15 Robert Dewar <dewar@adacore.com>
27859 Ed Schonberg <schonberg@adacore.com>
27860 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27862 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27863 Must_Be_Byte_Aligned for cases where we do not need to use a
27864 System.Pack_nn unit.
27866 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27868 Needed now that we do some processing for IN parameters as well. This
27869 may well fix some unrelated errors.
27870 (Expand_Call): Handle case of unaligned objects (in particular those
27871 that come from packed arrays).
27872 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27873 renamed entity is an inherited operation, re-expand the call using the
27874 original operation, which is the one to call.
27875 Detect attempt to inline parameterless recursive subprogram.
27876 (Represented_As_Scalar): Fix to work properly with private types
27877 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27878 accurate estimate. Yields True in far fewer cases than before,
27879 improving the quality of code that depends on this test.
27881 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27882 over both visible and private declarations to remove them from tree,
27883 and mark subprograms declared in package as eliminated, to prevent
27884 spurious use in subsequent compilation of generic units in the context.
27886 * exp_util.ads: Minor cleanup in variable names
27888 * sem_eval.ads, sem_eval.adb: Minor reformatting
27889 (Compile_Time_Known_Bounds): New function
27891 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27893 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27894 determining whether an unchecked conversion is needed for the argument
27895 of an initialization call.
27897 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27899 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27900 that appears in the instantiation rather than the internal subtype
27901 generated in the wrapper package, to avoid anomalies in gigi when the
27902 target is derived from a private type whose full view is an access type.
27904 2005-03-15 Robert Dewar <dewar@adacore.com>
27906 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27908 Add documentation to replace the use of this flag
27909 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27912 2005-03-15 Thomas Quinot <quinot@adacore.com>
27914 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27915 here from exp_attr so it can be shared between exp_attr and exp_dist.
27916 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27917 all TSS names, not a subset thereof, and the previous name introduced
27918 an unnecessarily confusion that a distinction might exist between
27919 "OK" TSS names and some "not OK" TSS names.
27921 2005-03-15 Doug Rupp <rupp@adacore.com>
27923 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27926 2005-03-15 Pascal Obry <obry@adacore.com>
27927 Eric Botcazou <ebotcazou@adacore.com>
27931 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27932 when IN_RTS. This is to work around a bootstrap path problem.
27934 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27935 table and pass it to __gnat_install_SEH_handler().
27936 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27938 * lang.opt: Fix specification of -fRTS=.
27940 2005-03-15 Doug Rupp <rupp@adacore.com>
27941 Bernard Banner <banner@adacore.com>
27942 Vincent Celier <celier@adacore.com>
27943 Arnaud Charlet <charlet@adacore.com>
27946 This change works fine when gnatlib is built from the gcc directory,
27947 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27948 is not passed to ada/Makefile.in, so more work is needed by a
27949 Makefile/configure expert.
27951 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27952 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27953 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27955 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27956 Run ranlib on libgccprefix.a
27957 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27958 (ADA_INCLUDE_SRCS): Split Ada packages.
27960 2005-03-15 Robert Dewar <dewar@adacore.com>
27962 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27964 * impunit.adb: Add GNAT.UTF_32
27966 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27968 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27969 now uses GNAT.UTF_32).
27971 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27972 capabilities for categorizing characters using Unicode categories
27974 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27976 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27977 instantiation that has been rewritten as a package body, retrieve spec
27978 to generate proper name for implicit_with_clause.
27979 (Install_Parents): Recognize a parent that is an instantiation but has
27980 been rewritten as a package declaration during analysis.
27982 2005-03-15 Javier Miranda <miranda@adacore.com>
27983 Ed Schonberg <schonberg@adacore.com>
27985 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27986 parameter reported some error we immediately return. This improves the
27987 behaviour of the frontend in case of errors.
27988 (Install_Parent, Remove_Parent): Introduce new flag
27989 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27990 ancestor of a generic child unit, when the child is being instantiated.
27991 (Inline_Instance_Body): If we are compiling the private
27992 part or the body of a child unit, restore the proper visibility of the
27993 parents after compiling the instance body.
27995 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27996 Javier Miranda <miranda@adacore.com>
27999 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
28000 of a private type, in which case it is underlying_type that denotes
28001 the proper task. Also modified to use the new entity attribute
28002 that is directly available in the task type and task subtype entities
28003 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
28004 arrays when other dimensions than the first are constrained by
28005 discriminants of an enclosing record.
28006 (Insert_Explicit_Dereference): If the prefix is an indexed component or
28007 a combination of indexed and selected components, find ultimate entity
28008 and generate the appropriate reference for it, to suppress spurious
28010 (Note_Possible_Modification): If an entity name has no entity, return.
28011 (Is_Variable): A function call never denotes a variable.
28012 (Requires_Transient_Scope): For record types, recurse only on
28013 components, not on internal subtypes that may have been generated for
28014 constrained components.
28016 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28018 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
28019 Eliminated as candidates for resolution. Both efficient, and avoids
28020 anomalies with operators declared in deleted code.
28021 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
28022 expansion is disabled (as when compiling a generic) to prevent spurious
28023 warnings on prefixes of selected components.
28025 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28027 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
28028 attached to a list before checking whether it appears in the private
28029 declarations of the current package.
28030 (Make_Inequality_Operator): Insert declaration in proper declarative
28031 list rather than just setting the Parent field, so that
28032 Is_Private_Declaration can handle it properly.
28034 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28036 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
28037 a renaming a body, check that the renamed subprogram in not intrinsic.
28038 (Find_Direct_Name): If several use_visible entities hide
28039 each other, and the context is a predefined file compiled through
28040 rtsfind, keep only the entity that comes from a predefined file.
28042 2005-03-15 Geert Bosch <bosch@adacore.com>
28044 * s-fatgen.adb (Valid): Extend special exceptions to account for long
28045 long float padding to also cover AMD64 and IA64.
28047 2005-03-15 Gary Dismukes <dismukes@adacore.com>
28049 * s-imgwch.adb: Add with and use of Interfaces.
28050 (Img_Wide_Character): Change type of Val to Unsigned_16.
28051 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
28053 2005-03-15 Matthew Gingell <gingell@adacore.com>

28099 Sergey Rybin <rybin@adacore.com>
28101 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
28102 too specific and long-winded to be appropriate for the GNAT User's
28104 Warn about use of GCC switches not documented in the GNAT User's Guide,
28105 as these may cause generated code to not conform to Ada semantics.
28106 Remove mention of -gdwarf-2 for sparc64, since this is now the default.

28235 This includes proper initialization with Normalize_Scalars.
28236 (Get_Simple_Init_Val): Major rewrite for initialize scalars and
28237 normalize scalars cases (particularly the latter) to do a better job
28238 of finding invalid representations.

28372 (Resolve_Slice): If the prefix is an access to an unconstrained array,
28373 compute the actual subtype of the designated object to impose the proper
28375 (Resolve_Selected_Component): Do not insert an access check if the
28376 prefix is an access type: such a node is expanded into an explicit
28377 dereference, on which the access check is performed anyway. Removes
28378 expensive duplicate checks.
28379 (Resolve_Call): Use new flag Is_Obsolescent and field
28380 Obsolescent_Warning so that pragma Obsolescent works on library
28382 Add support for wide wide character type
28383 (Resolve_Allocator): Replace the error message on wrong null-exclusion
28384 value by a warning message.
28385 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
28386 as fixed-point, and one of the operands is non-static and universal, it
28387 can only be an illegal exponentiation operation, in which case there is
28388 no real value to retrieve.
28390 * exp_strm.adb: Add support for wide wide character type
28391 (Build_Elementary_Input_Call): Compute the size of the stream element by

28432 (Is_Variable_Prefix): For the case of an indexed component whose prefix
28433 has a packed array type, the prefix has been rewritten into a type

28439 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28440 Remove ["0A"] from comment, since it can look like a line terminator.
28441 Currently we don't permit this, but this is under discussion by the
28442 ARG, and it is easy enough to use a different example.

28503 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28504 describing the new layout.
28505 (Dispatch_Table): The expander computes the actual array size, allocates
28506 the Dispatch_Table record accordingly, and generates code that displaces
28507 the base of the record after the Typeinfo_Ptr component. The access to
28508 these components is done by means of local functions.
28509 (Offset_To_Top): New function.
28510 (Typeinfo_Ptr): New function.
28511 (Get_TSD): Modified to access the new position of the TSD.

28522 N_Formal_Subtype_Declaration (which is now a subtype).
28523 (Analyze_Formal_Subprogram): Add handling for
28524 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28525 dispatching, setting the controlling status of the formal parameters
28526 and result, and issuing an error if there is no controlling type for
28527 the formal subprogram.
28528 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28529 which is an unclean use of that field, we set the new field
28530 Corresponding_Formal_Spec to make the formal subprogram available to

28532 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28533 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type

28538 abstract formal subprograms in error check for functions returning
28539 abstract types. Set scope of new designator for

28542 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28543 subprogram only if inner one comes from source.
28544 (Analyze_Function_Call): If the call is given in object notation, the
28545 analysis of the name rewrites the node and analyzes it with the proper
28546 argument list. After analyzing the name, if the call has been rewritten
28547 and the result type is set, no further analysis is needed.
28548 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28549 mark in function specification, in a context where the formals are
28550 visible and hide outer homographs.
28552 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28553 as the tagged type for the cases of abstract formal subprograms and
28554 renamings of those. Clean up spec comments.
28555 (Check_Dispatching_Context): Add error message to indicate "abstract
28556 procedure", covering the case of a call to a formal abstract procedure
28557 that has statically tagged operands.
28558 (Check_Dispatching_Call): Check for the case of an actual given by
28559 a tag-indeterminate function call whose type is an ancestor of the
28560 containing call's associated tagged type. This situation can occur
28561 for inherited primitives with function defaults. In this case we
28562 use the tagged type's tag directly as the controlling argument for
28564 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28566 * sprint.adb (Sprint_Node_Actual): Split
28567 N_Formal_Subprogram_Declaration into two alternatives for the new

28666 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28667 component of an array of arrays in an assignment context, and the
28668 aggregate has component associations that require sliding on
28669 assignment, force reanalysis of the aggregate to generate a temporary
28670 before the assignment.
28671 (Must_Slide): Make global to the package, for use in Gen_Assign.
28673 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28675 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28676 unchecked union with no inferable discriminants, return a
28677 Raise_Program_Error node, rather than inserting it at the point the
28679 (Expand_Record_Equality, Component_Equality): Handle properly the case
28680 where some subcomponent is an unchecked union whose generated equality
28681 code raises program error.
28683 2005-02-09 Doug Rupp <rupp@adacore.com>
28685 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.

28689 Arnaud Charlet <charlet@adacore.com>
28691 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28692 address of the exception registration. The Win32 version of this
28693 routine calls __gnat_install_SEH_handler() to initialize the SEH
28694 (Structured Exception Handling) handler.
28695 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28696 SEH (Structured Exception Handling) now.
28697 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28698 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28699 preprocessor condition protecting the call to the extra eh setup
28700 subprogram, which is only available for the ppc target.
28701 (__gnat_clear_exception_count): replaced reference to
28702 variable taskIdCurrent by call to taskIdSelf(), cleaner.
28704 * seh_init.c: New file.

28710 routine takes a new parameter (a pointer to the exception registration
28711 for the SEH (Structured Exception Handling) support.
28713 * raise.h: (__gnat_install_SEH_handler): New prototype.
28714 Update copyright notice.
28716 * s-tassta.adb (Task_Wrapper): Declare the exception registration

28746 2005-02-09 Vincent Celier <celier@adacore.com>
28748 * prj-makr.adb (Process_Directory): Put file name in canonical case
28749 before matching against the patterns.
28750 If gnatname has been invoked as <prefix>-gnatname
28751 then invoke the compiler as <prefix>-gcc, not just "gcc".

28755 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28756 with expansion disabled. The actual subtype is needed among other
28757 places when the selected component appears in the context of a loop
28758 bound, and denotes a packed array.
28759 (Operator_Check): Always use the first subtype in the
28760 error message, to avoid the appearance of internal base types.
28761 (Transform_Object_Operation): Copy each actual in full
28762 to the parameter associations of the constructed call, rather than
28763 using the shallow copy mechanism of New_Copy_List. This ensures that
28764 the chaining of named associations is done properly.
28765 (Complete_Object_Operation): Rewrite node, rather than

29559 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29560 with an implicit dereference as its prefix, use
29561 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29563 prefix is generated, if appropriate.
29565 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29566 dereference is rewritten to an explicit one, generate a reference to
29567 the entity denoted by its prefix using the original prefix node, so

29569 access value, if appropriate.
29571 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29572 emitting 'assigned but never read' warning on a variable on the basis

29588 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29589 subprogram which is Imported with convention Intrinsic if an
29590 External_Name argument is specified.
29591 (Process_Import_Or_Interface): Properly diagnose link name argument.
29592 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

29617 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29618 PCS-specific part of Add_Stub_Type.

29648 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29649 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29650 the body, to ensure that warnings are properly emitted for each accept
29651 statement of a given task entry.

29673 (Remove_Next_Debug): Same fix
29675 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do

29683 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29684 used to record an implicit dereference as a read operation on its
29685 prefix when operating under -gnatc. Necessary to avoid spurious
29686 'variable assigned but never read' warnings in that mode.
29687 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29688 is a non-overloaded implicit dereference, call the above subprogram to
29689 ensure proper recording of references.
29691 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29693 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

29741 2004-12-07 Vincent Celier <celier@adacore.com>
29743 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29744 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29745 and -eit to -ept. Added qualifier

29752 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29754 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29755 internal implementation unit GNAT.Sockets.Thin,
29756 as their usage for sockets is non-portable (using the read and write

29758 work under Windows).
29760 * mingw32.h: Update copyright notice.
29762 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29764 * ada-tree.h: Minor reformatting of previous change to avoid lines
29765 longer than 79 characters.
29767 2004-11-25 Olivier Hainque <hainque@adacore.com>
29769 * tb-gcc.c: GCC infrastructure based implementation of
29772 2004-11-24 Steven Bosscher <stevenb@suse.de>
29774 * misc.c (gnat_post_options): Don't clear
29775 flag_inline_functions.
29777 2004-11-22 Andrew Pinski <pinskia@physics.uc.edu>
29780 * ada-tree.h (lang_tree_node): Set chain_next to be the chain of the
29783 2004-11-21 Andreas Jaeger <aj@suse.de>
29785 * stylesw.adb: Change Style_Check_Subprogram_Order to
29786 Style_Check_Order_Subprograms.
29788 2004-11-18 Arnaud Charlet <charlet@adacore.com>
29790 * adaint.h, adaint.c
29791 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
29793 Add also a cast to kill another warning.
29794 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
29795 parameter with the priority class of the parent process instead of
29796 always using the NORMAL_PRIORITY_CLASS.
29797 (__gnat_dup): New function.
29798 (__gnat_dup2): New function.
29799 (__gnat_is_symbolic_link): Enable the effective body of this
29800 function when __APPLE__ is defined.
29802 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
29805 2004-11-18 Olivier Hainque <hainque@adacore.com>
29807 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
29808 address of which may be used to represent "others" and "all others"
29809 choices in exception tables, instead of the current harcoded
29810 (void *)0 and (void *)1.
29811 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29813 * gigi.h (others_decl, all_others_decl): New decls representing the
29814 new Others_Value and All_Others_Value objects.
29815 (struct attrib): Rename "arg" component as "args", since GCC expects a
29816 list of arguments in there.
29818 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29819 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29822 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29823 others_decl and all_others_decl instead of hardcoded dummy addresses
29824 to represent "others" and "all others" choices, which is cleaner and
29825 more flexible with respect to the possible eh pointer encoding policies.
29827 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29828 (process_attributes): Account for the naming change of the "args"
29829 attribute list entry component.
29831 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29832 cumulating attributes for different entities into a single list.
29833 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29834 attributes for the current entity and propagate first subtype
29835 attributes to other subtypes.
29836 <E_Procedure>: Attribute arguments are attr->args and not
29837 attr->arg any more.
29838 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29839 argument provided, as this is what GCC expects. Use NULL_TREE instead
29842 2004-11-18 Robert Dewar <dewar@adacore.com>
29844 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
29845 Minor reformatting througout (including new function specs)
29846 Add ??? comments asking for clarification.
29848 2004-11-18 Thomas Quinot <quinot@adacore.com>
29850 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
29851 incomplete duplicate implementation of this subprogram from butil.
29853 2004-11-18 Thomas Quinot <quinot@adacore.com>
29855 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
29856 procedures factors the common processing for building an RPC receiver
29857 for an RCI package or an RACW type.
29858 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
29859 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
29860 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
29862 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
29864 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
29866 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
29867 distribution subprogram identifiers that are either subprogram numbers
29869 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
29870 string distribution identifiers assigned to a given subprogram.
29871 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29872 (Add_RAS_Dereference_TSS): Add comments.
29873 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29874 is not referenced yet because it will be used by the PolyORB DSA
29876 (Insert_Partition_Check): Remove fossile code.
29877 (First_RCI_Subprogram_Id): Document this constant.
29878 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29880 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29881 replaced with calls to Get_Library_Unit_Name_String. Previously there
29882 were several instances of the same code in different locations in the
29883 compiler; this checkin completes the replacement of all of these
29884 instances with calls to a common subprogram.
29885 Minor reformatting.
29887 * sem_dist.adb: Remove comment noting that RPC receiver generation
29888 should be disabled for RACWs that implement RASs.
29889 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
29891 * sem_util.ads, sem_util.adb (Has_Stream): New function
29892 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
29893 qualified name of a library unit into the name buffer.
29894 (Note_Possible_Modification): Generate a reference only
29895 if the context comes from source.
29897 * snames.ads (PCS_Names): New subtype corresponding to names of
29898 supported implementations of the Partition Communication Subsystem
29899 (PCS) (i.e. the runtime library support modules for the distributed
29902 2004-11-18 Robert Dewar <dewar@adacore.com>
29903 Ed Schonberg <schonberg@adacore.com>
29905 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
29906 (Has_Rep_Pragma): New function
29907 (Has_Attribute_Definition_Clause): New function
29908 (Record_Rep_Pragma): Moved here from sem_ch13.adb
29909 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
29911 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
29913 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29914 (Expand_Pragma_Psect_Object): New procedure
29915 These procedures contain the revised and cleaned up processing for
29916 these two pragmas. This processing was formerly in Sem_Prag, but
29917 is more appropriately moved here. The cleanup involves making sure
29918 that the pragmas are properly attached to the tree, and that no
29919 nodes are improperly shared.
29921 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29922 pragmas to Exp_Prag, which is more appropriate.
29923 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29924 check for duplicates Remove use of Is_Psected flag, no longer needed.
29925 Use new Make_String_Literal function with string.
29927 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29928 that are functions return universal values, that have to be converted
29929 to the context type.
29930 Use new Make_String_Literal function with string.
29931 (Get_Stream_Convert_Pragma): New function, replaces the use of
29932 Get_Rep_Pragma, which had to be kludged to work in this case.
29934 * freeze.adb: Use new Has_Rep_Pragma function
29936 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29937 function with string.
29938 Use new Has_Rep_Pragma function.
29940 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29943 2004-11-18 Robert Dewar <dewar@adacore.com>
29945 * errout.ads, errout.adb: (First_Sloc): New function
29947 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29948 check (-gnatyx) instead of being included as a redundant construct
29951 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29952 Style_Check_Order_Subprograms.
29954 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29955 stylesw.adb: Add Style_Check_Xtra_Parens
29957 * usage.adb: Add line for -gnatyx (check extra parens)
29959 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29961 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29962 Robert Dewar <dewar@adacore.com>
29964 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29965 discriminant of a constrained subtype, analyze the copy of the
29966 corresponding constraint, because in some cases it may be only
29967 partially analyzed.
29968 Removes long-lived ??? comments.
29970 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29971 handled controlled or secondary-stack expressions within the
29972 iteration_scheme of a loop.
29974 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29975 bounds that may contain functions calls, to prevent memory leaks when
29976 the bound contains a call to a function that uses the secondary stack.
29977 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29978 generate temporaries for loop bounds that might contain function calls
29979 that require secondary stack and/or finalization actions.
29981 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29982 selected component and the selector is overloadable (not just a
29983 function) treat as function call, Analyze_Call will disambiguate if
29985 (Analyze_Selected_Component): Do not generate an actual subtype for the
29986 selected component if expansion is disabled. The actual subtype is only
29987 needed for constraint checks.
29988 (Analyze_Allocator): If restriction No_Streams is set, then do
29989 not permit objects to be declared of a stream type, or of a
29990 composite type containing a stream.
29992 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29993 No_Streams no longer prohibits with'ing this package.
29995 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29996 discriminants, but the parent base has unknown discriminants, there is
29997 no discriminant constraint to inherit. Such a discrepancy can arise
29998 when the actual for a formal type with unknown discriminants is a
29999 similar private type whose full view has discriminants.
30000 (Analyze_Object_Declaration): If restriction No_Streams is set, then
30001 do not permit objects to be declared of a stream type, or of a
30002 composite type containing a stream.
30004 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30006 * exp_dbug.ads: Update documentation to reflect simpler encoding for
30007 protected operations.
30009 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
30010 generated name, it complicates decoding in gdb and hinders debugging
30011 of protected operations.
30012 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
30013 flag for the protected entry barrier function.
30014 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
30015 flag for the protected entry function.
30017 2004-11-18 Nicolas Setton <setton@adacore.com>
30019 * expect.c: Define __unix__ when __APPLE__ is defined.
30021 * Makefile.in: Inform the value of the variable GMEM_LIB in the
30022 Darwin-specific section.
30024 * lang-specs.h: Change the placement of the %1 marker.
30025 Works around the fact that gcc adds -fPIC by default under Darwin.
30027 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30029 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
30030 type of the object with the packed array type, set the Analyzed flag
30031 on the object if it is an entity or simple indexed component, to avoid
30032 spurious type errors.
30034 2004-11-18 Gary Dismukes <dismukes@adacore.com>
30036 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
30037 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
30038 separate line from the version message.
30040 2004-11-18 Ed Falis <falis@adacore.com>
30042 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
30044 (init_float): Eliminate initialization of floating point status for
30045 AE653. The instructions have no effect for vThreads.
30047 2004-11-18 Vincent Celier <celier@adacore.com>
30049 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
30050 gnatbind is invoked with -shared.
30052 2004-11-18 Jose Ruiz <ruiz@adacore.com>
30054 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
30055 for Detect_Blocking which is redundant with the check done within the
30056 procedure Protected_Single_Entry_Call.
30057 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
30058 Detect_Blocking which is redundant with the check done within the
30059 procedure Protected_Single_Entry_Call.
30061 2004-11-18 Vincent Celier <celier@adacore.com>
30063 * makegpr.adb (Compile): Put the compiling switches (in package
30064 Compiler and on the command line) immediately after "-c", instead of
30065 at the end of the command line invocation of the compiler, when
30066 compiling a non-Ada file.
30067 (Build_Global_Archive): When there is no need to rebuild the archive,
30068 set Global_Archive_Exists, so that the archive is passed to the linker
30071 2004-11-18 Robert Dewar <dewar@adacore.com>
30072 Sergey Rybin <rybin@adacore.com>
30075 Remove extra paren check from list of checks for redundant constructs
30076 Add documentation of new -gnatyx style check (check extra parens)
30077 Remove paragraph about gnatelim debug options.
30079 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
30080 objects rather than forbidding dependencies on the package Ada.Streams.
30082 * sinfo.ads: Add ??? note that we should document pragmas passed to
30085 * g-expect.ads: Fix a few typos in the comments.
30087 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
30089 * misc.c (gnat_handle_option): Use %< and %> for quoting in
30092 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
30094 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
30096 2004-11-07 Andreas Schwab <schwab@suse.de>
30098 * Makefile.in (install-gnatlib): Remove spurious hyphen.
30100 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
30103 * Makefile.in (darwin): Set soext to .dylib.
30105 2004-10-26 Vincent Celier <celier@gnat.com>
30106 Thomas Quinot <quinot@act-europe.fr>
30108 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
30109 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
30110 there is no use of GNAT.Sockets.Constants.
30111 Remove remaining pragma Import for C_Write
30112 Remove C_Read and C_Write from internal implementation unit
30113 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30114 the read and write functions from the system runtime library is fine
30115 on UNIX but won't work under Windows).
30117 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30118 (Check_Selector): Use C_Recv instead of C_Read.
30119 Selectors are the GNAT.Sockets abstraction to perform a select()
30120 call on a set of descriptors. To allow abortion of an ongoing
30121 select operation, some data is written to a dedicated socket that
30122 is always monitored.
30123 Under Windows, the write and read library functions cannot operate
30124 on sockets, so we need to use send and recv instead, which is portable
30125 across all supported platforms.
30127 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
30128 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
30129 (using the read and write functions from the system runtime library is
30130 fine on UNIX but won't work under Windows).
30132 2004-10-26 Nicolas Setton <setton@act-europe.fr>
30134 * mlib-tgt-darwin.adb: New file.
30136 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30137 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30138 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
30139 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
30142 * Makefile.in: Add support for building shared libraries under Darwin.
30143 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
30144 the low level EH init subprogram to be called from __gnat_initialize.
30146 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
30147 indicates which options to pass to the archive indexer.
30149 * mlib-utl.adb: Add support for calling ranlib with additional
30150 options. This is needed for instance under Mac OS X.
30151 (Ranlib_Options): New global variable, used to store the potential
30152 options to pass to ranlib.
30153 (Ar): Use Ranlib_Options when spawning ranlib.
30154 (Initialize): Set the value of ranlib option.
30156 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30158 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30159 instead of 8K, to reflect the real potential needs for stack-checking
30162 2004-10-26 Pascal Obry <obry@gnat.com>
30164 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30166 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30167 Windows only the initial thread stack size can be set so it is good to
30168 start we a low stack size.
30169 The OS will adjust the size as needed.
30171 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30172 Nicolas Setton <setton@act-europe.fr>
30174 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30175 "__unix__" instead of "unix".
30176 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30177 sections were just mistakenly ignored. The former is
30178 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30179 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30180 of hpux. This prevents an unwanted definition of the symbol
30181 convert_addresses in adaint.o.
30183 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30185 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30186 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30188 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30190 * a-filico.ads, a-filico.adb: fix incorrect header.
30192 2004-10-26 Javier Miranda <miranda@gnat.com>
30194 * a-ststio.ads: Fix typo in identifier
30196 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30198 * sem_ch4.adb: Minor reformatting.
30200 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30202 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30203 enabled, check the result of unary and binary operations when the
30204 expression is the right-hand side of an assignment.
30206 2004-10-26 Vincent Celier <celier@gnat.com>
30208 * clean.adb (Delete): Do not output warnings when in quiet output and
30209 not in verbose mode.
30210 (Force_Deletions): New Boolean flag, defaulted to False
30211 (Delete): Only delete a file if it is writable, and when
30212 Force_Deletions is True.
30213 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30214 (Usage): Line for new switch -f
30215 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30218 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30220 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30221 JM type only if its size matches that of the wrapper. When a size is
30222 prescribed and the field is not aliased, remove the wrapper of a JM
30223 type only if the size is not greater than that of the packed array.
30224 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30227 2004-10-26 Geert Bosch <bosch@gnat.com>
30229 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30230 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30231 (Pred): Implement in terms of Succ.
30233 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30235 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30236 unchecked conversion is safe for in-place use if the expression of the
30237 conversion is safe.
30238 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30239 be expandable in place even if the aggregate does not come from source.
30240 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30241 designated object of an allocator in place, rather than building it
30242 first on the stack. The previous scheme forces a full copy of the array,
30243 and may be altogether unsusable if the size of the array is too large
30244 for stack allocation.
30246 2004-10-26 Robert Dewar <dewar@gnat.com>
30248 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30249 compares if the component is atomic.
30251 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30252 array assignment if the component type is atomic.
30254 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30255 Eric Botcazou <ebotcazou@act-europe.fr>
30257 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30258 is aliased and is a by_reference type, do not pass by copy.
30259 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30260 detect whether the call is in the right side of an assignment or
30261 the expression of an object declaration. Recurse on component
30262 association within aggregates.
30263 Call it in the condition that determines whether the temporary is
30264 necessary for correct stack-checking.
30266 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30268 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30269 RACW_Type, used in the PolyORB version.
30270 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30271 version and the GARLIC version.
30273 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30274 Rename RCI_Info to RCI_Locator for better consistency between the
30275 GARLIC and PolyORB versions of the distributed systems annex.
30276 (DSA_Implementation_Name): This enumeration lists the possible
30277 implementations of the Partition Communication Subsystem for the
30278 Distributed Systems Annex (DSA). The three available implementations
30279 are the dummy stub implementation (No_DSA), and two versions based on
30280 two different distribution runtime libraries: GARLIC and PolyORB. Both
30281 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30283 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30286 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30287 between the GARLIC and PolyORB versions of the distributed systems
30289 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30291 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30293 * gnat1drv.adb: Suppress calling the back end when
30294 Frontend_Layout_On_Target is true.
30296 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30298 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30299 Set_Read_Only): New subprograms.
30300 These new routines allow the user to set or unset the Owner execute
30301 and Owner write permission flags on a file.
30303 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30304 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30306 2004-10-26 Matthew Gingell <gingell@gnat.com>
30308 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30310 2004-10-26 Pascal Obry <obry@gnat.com>
30312 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30313 memory before the faulting page we properly test the process read
30314 access for this address using appropriate Win32 routine.
30315 (HPUX sections): guard with "__hpux__" instead of "hpux".
30317 2004-10-26 Robert Dewar <dewar@gnat.com>
30319 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30320 entry parameter if pragma Unreferenced set, since we do not properly
30321 handle the case of multiple parameters.
30323 2004-10-26 Vincent Celier <celier@gnat.com>
30325 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30326 (Ada_Objects_Path.Add): For a library project, add to the object path
30327 the library directory only if there is no object directory or if the
30328 library directory contains ALI files.
30329 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30331 2004-10-26 Vincent Celier <celier@gnat.com>
30333 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30334 extension of library projects.
30336 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30337 path defaults to ".:<prefix>/lib/gnat".
30338 (Parse): For an extending all project, allow direct import of a project
30339 that is virtually extended.
30341 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30342 the specified name is directly imported, return its ID. Otherwise, if
30343 an extension of this project is imported, return the ID of the
30346 2004-10-26 Robert Dewar <dewar@gnat.com>
30348 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30349 (Sub3): New procedure, used by Scaled_Divide
30350 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30351 correct more than one instance of failure to propagate carries
30353 (Double_Divide): Handle overflow case of largest negative number
30354 divided by minus one.
30356 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30357 the case of a quotient value out of range.
30360 2004-10-26 Robert Dewar <dewar@gnat.com>
30362 * s-bitops.adb (Bit_Eq): Remove redundant check.
30364 * s-bitops.ads: Minor comment updates
30365 Change some occurrences of Address to System.Address
30367 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30369 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30371 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30372 accessibility check to prefix that is a protected operation.
30374 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30376 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30377 empty, post message on stub.
30379 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30380 Javier Miranda <miranda@gnat.com>
30382 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30383 current instance appears within a unit that is directly in the context
30385 Used to determine whether the body of the instance should be analyzed
30386 immediately after its spec, to make its subprogram bodies available
30387 for front-end inlining.
30388 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30389 constraint is not allowed on the component type (AARM 12.5.3(3))
30391 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30393 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30394 'Storage_Pool): enhance, document & limit detection of non-sharable
30397 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30399 * s-pooglo.ads: Add more documentation now that this pool is properly
30402 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30404 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30405 or protected type with discriminants, do not constrain the
30406 corresponding record type if the subtype declaration has no
30407 discriminant constraints. This can be the case in source code, or in
30408 the subtype declaration created to rename an actual type within an
30411 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30413 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30414 different kind of stub (possibly wrong name for file), do not check
30416 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30417 includes call to some function that returns an unconstrained type, do
30420 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30422 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30423 appear in the code for the main unit. Dependencies among units in the
30424 context of the main unit are established when those other units are
30425 compiled. Otherwise spurious elaboration constraints can generate
30426 incorrect elaboration circularities.
30428 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30429 Ed Schonberg <schonberg@gnat.com>
30431 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30432 subprogram is called with a parameter that is not an object name. This
30433 situation arises for some cases of illegal code, which is diagnosed
30434 later, and in this case it is wrong to call Is_Aliased, as that might
30435 cause a compiler crash.
30436 (Explain_Limited_Type): Refine previous fix to include
30437 inherited components of derived types, to provide complete information.
30439 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30440 is the prival for a protected object.
30441 It is necessary to mark this entity as a variable, in addition to
30442 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30443 modified to avoid checking the Aliased flag on entities that are not
30444 objects. (Checking that flag for non-objects is erroneous and could
30445 lead to a compiler crash).
30447 2004-10-26 Robert Dewar <dewar@gnat.com>
30449 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30450 X_Frac = 0.5, then we know that the number X must be positive.
30451 (Succ): Remove the same redundant test, and also fix the primary test
30452 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30454 (Decompose): Add fuller comments to spec
30456 2004-10-26 Pascal Obry <obry@gnat.com>
30458 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30459 validity (process must have read access). Set to 0 in all other cases.
30460 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30461 violation on Win32.
30462 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30463 segmentation violation.
30465 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30467 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30468 whose type is a constructed subtype of an aliased object with an
30469 unconstrained nominal subtype, convert the actual to the constructed
30470 subtype before taking its address.
30472 2004-10-26 Vincent Celier <celier@gnat.com>
30474 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30475 (Is_Path_Name_Case_Sensitive): New function
30477 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30478 (Base_Name, Simple_Name, Current_Directory, Compose,
30479 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30482 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30483 Vasiliy Fofanov <fofanov@act-europe.fr>
30484 Vincent Celier <celier@gnat.com>
30486 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30487 "memory management issues" section and document some of the useful
30488 memory pools provided as part of the GNAT library.
30489 Remove "virtual" from declaration of A::method2 in
30490 the simple example of Ada/C++ mixed system.
30491 Library Projects may be virtually extended: their virtual extensions
30492 are not Library Projects.
30493 Added section on extending project hierarchies.
30495 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30497 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30499 (__gnat_portable_spawn): Remove const.
30501 * mingw32.h (MAXPATHLEN): Check for previous definition.
30503 2004-10-17 Matthias Klose <doko@debian.org>
30505 * gnatvsn.ads: Set gnat library version to 4.0.
30507 2004-10-05 Vincent Celier <celier@gnat.com>
30509 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30511 2004-10-04 Laurent Guerby <laurent@guerby.net>
30514 * Makefile.in: Define and use RANLIB_FLAGS.
30516 2004-10-04 Pascal Obry <obry@gnat.com>
30518 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30519 other x86 platforms).
30521 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30523 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30524 in general and triggers stack alignment adjustment for thread entry
30525 points on targets where this is necessary.
30527 2004-10-04 Bernard Banner <banner@gnat.com>
30530 * Makefile.in: Add section for powerpc linux
30531 Add variant i-vxwork-x86.ads
30533 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30535 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30537 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30538 table registration calls when need be. Ensures no reference to the crt
30539 ctors symbol are issued in the SJLJ case, which avoids possible
30540 undefined symbol errors in the case of modules to be statically linked
30543 2004-10-04 Javier Miranda <miranda@gnat.com>
30545 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30546 in-line the code corresponding to subprogram Analyze_Actuals. In
30547 addition, analyze the actuals only in case of subprogram call.
30549 2004-10-04 Ed Falis <falis@gnat.com>
30551 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30553 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30555 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30556 in the documentation.
30558 2004-10-04 Robert Dewar <dewar@gnat.com>
30560 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30562 (Analyze_Block_Statement): Add circuitry to detect following dead code
30563 (Check_Unreachable_Code): Handle case of block exit
30565 2004-10-04 Robert Dewar <dewar@gnat.com>
30567 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30568 (XMatchD): Avoid warning for Logic_Error call
30570 2004-10-04 Robert Dewar <dewar@gnat.com>
30572 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30573 consider expressions buried within a procedure actual to be an actual.
30574 This caused some blowups with uses of packed slices within a procedure
30577 2004-10-04 Robert Dewar <dewar@gnat.com>
30579 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30580 longer need to be initialized to zero.
30581 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30582 initialized to zero.
30584 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30585 considered valid, even if the representation is modular. That's correct
30586 now that we no longer initialize packed modular arrays to zero.
30588 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30589 suffixes. These are now documented as the only cases in which the
30590 debugger ignores outer records.
30591 Previously, the spec allowed arbitrary suffixes for this purpose.
30592 Change name of LJM to JM for packed array pad records
30593 Create separate section on packed array handling, and add a whole new
30594 set of comments to this section describing the situation with packed
30595 modular types and justification requirements depending on endianness.
30597 2004-10-04 Robert Dewar <dewar@gnat.com>

30610 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30612 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30613 Inline_Always when in Configurable_Run_Time mode.
30615 * sem_prag.adb (Process_Convention): If entity is an inherited
30616 subprogram, apply convention to parent subprogram if in same scope.
30617 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30618 when in Configurable_Run_Time mode.
30620 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30622 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30623 class_wide type after component list has been inherited.

30627 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30628 Denotes_Previous_Actual, to handle properly the case of a private
30629 actual that is also the component type of a subsequent array actual.
30630 The visibility status of the first actual is not affected when the
30631 second is installed.
30632 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30633 make fully recursive the treatment of formals of packages declared
30635 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30636 the above on exit from an instantiation.
30637 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30638 current instantiation which is now complete.
30639 (Analyze_Package_Instantiation): No instantiated body is needed if the
30640 main unit is generic. Efficient, and avoid anomalies when a instance
30641 appears in a package accessed through rtsfind.
30643 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30645 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30646 do not generate a declaration for a temporary if the call is part of a
30647 library-level instantiation.
30649 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30651 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30652 searching for a limited component to flag.
30654 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30655 expansion of Input, to account for the fact that the implicit call
30656 generated by the attribute reference must freeze the user-defined
30657 stream subprogram. This is only relevant to 'Input, because it can
30658 appear in an object declaration, prior to the body of the subprogram.
30660 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30661 expansion can proceed and further errors uncovered.
30662 (Minor clean up): Fix cases of using | instead of \ for continuation

30676 stripped-down declaration for the type of the inner field when making
30679 * utils.c (finish_record_type): Do not compute the size in units
30680 incrementally. Instead compute it once for the rep clause case.
30681 Use gcc_assert and gcc_unreachable.
30683 2004-10-04 Vincent Celier <celier@gnat.com>
30685 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character

30691 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30692 (Extended_Project) only if Extended_Project is defined, to avoid
30694 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30696 (Parse_Single_Project): Ditto.
30698 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30699 Add_To_Project_Path for virtual projects.
30701 2004-10-04 Vincent Celier <celier@gnat.com>
30703 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

30707 parameter Options_2.
30709 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30710 Build_Dynamic_Library with an empty Options_2.
30712 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30715 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30716 directory separator, if any.
30717 (Gprmake): Do not allow mains on the command line for library projects.
30718 Do not attempt to link when the project is a library project.
30719 (Library_Opts): New table to store Library_Options.
30720 (Build_Library): If Library_Options is specified, pass these options
30721 when building a shared library.
30723 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30725 * s-tposen.adb (Service_Entry): The object must be always unlocked at

30745 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30746 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30747 used to signal whether the compiler creates the required stacks and
30748 descriptors for the different tasks (when True) or it is done by the
30749 underlying operating system at run time (when False).
30750 It is initially set to False in all targets.
30752 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30753 if it is supported by the target.
30754 (Make_Task_Create_Call): Pass the stack address if it has been
30755 previously created. Otherwise pass a Null_Address.
30757 * snames.adb: Add _stack.
30759 * snames.ads: Add Name_uStack. Required to allow the expander to
30760 statically allocated task stacks.
30762 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30763 Stack_Address argument.
30764 Check that its value is equal to Null_Address because this target does
30765 not support the static stack allocation.
30767 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30769 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30772 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30774 * exp_dist.adb: Split declaration of asynchronous flag out of
30775 Add_RACW_Read_Attribute.
30776 Minor reformatting for better alignment with PolyORB version.
30777 Store the entity for the asynchronous flag of an RACW, rather than the
30778 expression, in the asynchronous flags table. This will allow this flag
30779 to be used in other subprograms beside Add_RACW_Read_Attribute.
30781 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30783 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30785 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
30786 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
30787 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30788 sockets constant MSG_NOSIGNAL (Linux-specific).
30789 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30790 all Send operations.
30791 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30792 from trigerring SIGPIPE.
30793 Rename components to avoid clash with Ada 2005 possible reserved
30795 (Check_Selector): When the select system call returns with an error
30796 condition, propagate Socket_Error to the caller.

30806 instead do this at freeze time (we won't do it if there is an address
30808 Change "pragma inline" to "pragma Inline" in information and error
30810 Minor reformatting.
30812 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30813 right way of doing things after all.
30814 (Freeze_Entity): For object, set Is_Public for imported entities
30815 unless there is an address clause present.
30817 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30819 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30820 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30821 ensures proper handling of types with rep clauses, which might have
30822 their TYPE_SIZE set already.
30824 2004-09-21 Robert Dewar <dewar@gnat.com>
30826 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30827 packed array types in both little- and big-endian cases. This change
30828 ensures that we no longer count on the unused bits being initialized
30829 for such types (and in particular ensures that equality testing will
30830 only read the relevant bits).
30831 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30832 These changes mean that we no longer need to initialize small packed
30834 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30835 optimization to an LJM field as to its parent field.
30837 * ada-tree.h, trans.c, utils.c, utils2.c:
30838 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30840 2004-09-20 Jan Hubicka <jh@suse.cz>
30842 * utils.c (gnat_finalize): Remove.
30843 (end_subprog_body): Directly call cgraph_finalize_function;
30844 do not lower the nested functions.
30846 2004-09-20 Robert Dewar <dewar@gnat.com>
30849 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30850 if an address clause is present, since that means that the Import
30853 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30855 * 5tsystem.ads: Removed, no longer used.
30857 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30858 Zack Weinberg <zack@codesourcery.com>
30860 * ada-tree.def: Use tree_code_class enumeration constants
30861 instead of code letters.

30879 an existing directory.
30880 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30881 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30882 Convert the result to File_Size.
30884 * prj.ads: (Project_Error): New exception
30886 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30887 Prj.Com, not from Osint.
30888 (Attrs, Package_Attributes): Tables moved to private part of spec
30889 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30891 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30892 Prj.Project_Error after call to Fail.
30893 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30894 Fail. Check that package name is not already in use.
30896 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30897 used by tools, not only by the project manager, and to indicate that
30898 exception Prj.Prj_Error may be raised in case of problem.
30899 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30901 (Attrs, Package_Attributes): Table instantiations moved from the body to
30902 the private part to be accessible from Prj.Attr.PM body.
30904 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30905 from new package Prj.Attr.PM.
30906 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30909 * Makefile.in: Add prj-attr-pm.o to gnatmake object list

30956 * gnat_ugn.texi: Add Detect_Blocking to the list of configuration
30957 pragmas recognized by GNAT.
30959 * gnat_rm.texi: Document pragma Detect_Blocking.
30961 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
30962 raise Program_Error if called from a protected operation.
30964 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30965 the protected action nesting level.
30966 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30967 protected action nesting level.
30968 (Unlock): When pragma Detect_Blocking is active decrease the protected
30969 action nesting level.
30971 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30972 Protected_Action_Nesting.
30974 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30975 Common_ATCB record. It contains the dynamic level of protected action
30976 nesting for each task. It is needed for checking whether potentially
30977 blocking operations are called from protected operations.
30978 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30979 Detect_Blocking is active or not in the partition.
30981 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

31011 protected action nesting level.
31013 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
31014 insertion of the statement raising Program_Error. The run time
31015 contains the required machinery for handling that.
31017 * sem_util.ads: Change comment associated to procedure
31018 Check_Potentially_Blocking_Operation.
31019 This procedure does not insert a call for raising the exception because
31020 that is currently done by the run time.
31022 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
31024 * init.c: Add the global variable __gl_detect_blocking that indicates
31025 whether pragma Detect_Blocking is active (1) or not (0). Needed for
31026 making the pragma available at run time.
31027 (__gnat_set_globals): Pass and update the detect_blocking parameter.
31029 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
31030 pragma Detect_Blocking is active.
31032 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
31034 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
31035 DB is found in the ali file. Any unit compiled with pragma
31036 Detect_Blocking active forces its effect in the whole partition.
31038 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
31039 Detect_Blocking is active and delay is called from a protected
31042 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
31043 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
31044 Detect_Blocking is active (0 otherwise).
31045 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
31046 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
31049 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
31051 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
31052 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
31055 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
31056 (Register_Receiving_Stub): Add Subp_Info formal parameter.
31057 Update API in placeholder implemetation of s-parint to reflect changes
31058 in distribution runtime library.
31060 * sem_ch3.adb (Expand_Derived_Record): Rename to
31061 Expand_Record_Extension.
31063 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
31064 primitive operations of potentially distributed object types that have
31065 non-controlling anonymous access formals.
31067 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
31069 New implementation of expansion for remote access-to-subprogram types,
31070 based on the RACW infrastructure.
31071 This version of sem_dist is compatible with PolyORB/DSA as well as
31074 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
31075 Asynchrronous that applies to a remote access-to-subprogram type, mark
31076 the underlying RACW type as asynchronous.
31078 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
31079 __gnat_using_gnu_linker to 1.
31081 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
31082 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
31083 GNAT.Perfect_Hash_Generators, and remove the empty

31088 * exp_ch3.adb (Expand_Derived_Record): Rename to
31089 Expand_Record_Extension.
31090 (Build_Record_Init_Proc.Build_Assignment): The default expression in
31091 a component declaration must remain attached at that point in the
31092 tree so New_Copy_Tree copies it if the enclosing record type is derived.
31093 It is therefore necessary to take a copy of the expression when building
31094 the corresponding assignment statement in the init proc.
31095 As a side effect, in the case of a derived record type, we now see the
31096 original expression, without any rewriting that could have occurred
31097 during expansion of the ancestor type's init proc, and we do not need
31098 to go back to Original_Node.
31100 * exp_ch3.ads (Expand_Derived_Record): Rename to
31101 Expand_Record_Extension.
31103 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

31106 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
31107 New subprograms. Used to create a proxy tagged object for a remote
31108 subprogram. The proxy object is used as the designated object
31109 for RAS values on the same partition (unless All_Calls_Remote applies).
31110 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
31111 System.Partition_Interface.Get_Unique_Remote_Pointer.
31112 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
31113 Renamed from Add_RAS_*_Attribute.
31114 (Add_Receiving_Stubs_To_Declarations): Generate a table of local

31117 based on the RACW infrastructure.
31119 * exp_dist.ads (Copy_Specification): Update comment to note that this
31120 function can copy the specification from either a subprogram
31121 specification or an access-to-subprogram type definition.

31125 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
31126 in an instance, between an explicit subprogram an one inherited from a
31127 type derived from an actual.
31129 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
31130 add a polling call if the subprogram is to be inlined by the back-end,
31131 to avoid repeated calls with multiple inlinings.
31133 * checks.adb (Apply_Alignment_Check): If the expression in the address
31134 clause is a call whose name is not a static entity (e.g. a dispatching
31135 call), treat as dynamic.
31137 2004-09-09 Robert Dewar <dewar@gnat.com>
31139 * g-trasym.ads: Minor reformatting
31141 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

31150 2004-09-09 Pascal Obry <obry@gnat.com>
31152 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
31153 enable map file generation. Add the right option to generate the map
31154 file if Map_File is set to True.
31156 * gnatdll.adb (Gen_Map_File): New variable.
31157 (Syntax): Add info about new -m (Map_File) option.

31185 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31186 of variable length temporaries for function return now that the
31187 back-end and gigi support it.

31381 for a global aliased object with a variable size and an unconstrained
31382 nominal subtype, pretend there is no initializer if the one we have is
31383 incomplete, and avoid referencing an inexistant component in there. The

31411 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
31412 discriminants that rename those of the parent, recover names of
31413 original discriminants for the constraint on the full view of the

35651 * par.adb, memtrack.adb, prj-makr.adb, prj-part.adb,
35652 sem_util.adb: Minor reformatting
35654 * sem_ch12.adb: Add comment for previous change
35656 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
35658 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35659 executable name when not initialized. Otherwise, use its current value.
35661 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35662 initialize it to another executable name than the current one. This
35663 allows to configure paths for an executable name (gnatmake) different
35664 from the current one (gnatdist).
35666 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35668 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35669 current unit cannot be inlined if it appears in the body of a withed
35670 unit, to avoid order of elaboration problems in gigi.
35672 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35673 information for protected (wrapper) operation as well, to simplify gdb
35676 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35677 protected body, indicate that the entity for the generated spec comes
35678 from source, to ensure that references are properly generated for it.
35679 (Build_Body_To_Inline): Do not inline a function that returns a
35682 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
35683 apply convention to homonyms that are declared explicitly.
35685 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
35686 that renames an equality operator and the operands are overloaded,
35687 resolve them with the declared formal types, before rewriting as an
35690 2004-03-29 GNAT Script <nobody@gnat.com>
35692 * Make-lang.in: Makefile automatically updated
35694 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
35696 * memtrack.adb: Log realloc calls, which are treated as free followed
35699 2004-03-25 Vincent Celier <celier@gnat.com>
35701 * prj-makr.adb (Process_Directories): Detect when a file contains
35702 several units. Do not include such files in the config pragmas or
35703 in the naming scheme.
35705 * prj-nmsc.adb (Record_Source): New parameter Trusted_Mode.
35706 Resolve links only when not in Trusted_Mode.
35707 (Find_Sources, Recursive_Find_Dirs, Find_Source_Dirs, Locate_Directory):
35708 Do not resolve links for the display names.
35710 * prj-part.adb (Parse_Single_Project, Project_Path_Name_Of): Do not
35711 resolve links when computing the display names.
35713 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35715 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35716 attribute reference does not denote a subtype, it can be any
35717 expression that has a classwide type, potentially after an implicit
35718 dereference. In particular, the prefix can be a view conversion for
35719 a classwide type (for which Is_Object_Reference holds), but it can
35720 also be a value conversion for an access-to-classwide type. In the
35721 latter case, there is an implicit dereference, and the original node
35722 for the prefix does not verify Is_Object_Reference.
35724 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35725 conversion of a discriminant-dependent component of a mutable object
35728 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35730 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35731 inherited, has convention C, and has unconstrained array parameters,
35732 place the corresponding warning on the derived type declaration rather
35733 than the original subprogram.
35735 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35736 indication on renaming declaration, if formal has a box and actual
35739 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35740 determine whether to generate an implicit or explicit reference to
35741 the renamed entity.
35743 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35744 subprogram renaming comes from a defaulted formal subprogram in an
35747 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35749 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35750 value expressions to ensure that calls within a component definition
35751 will be checked (since those are evaluated during the record type's
35754 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
35756 * s-tpobop.adb: Code clean up:
35757 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated
35759 (PO_Do_Or_Queue): Remove duplicated code and use Requeue_Call.
35761 2004-03-25 Jose Ruiz <ruiz@act-europe.fr>
35763 * Makefile.in: Clean up in the ravenscar run time.
35765 2004-03-23 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35767 * decl.c (gnat_to_gnu_entity, case E_Access_Type): Pass value
35768 of No_Strict_Aliasing to build_pointer_type_for_mode.
35769 * utils.c (update_pointer_to): Walk pointer and ref chains.
35771 2004-03-22 Cyrille Comar <comar@act-europe.fr>
35773 * ali.ads: Fix Comment about Dynamic_Elab.
35775 * gnatls.adb (Output_Unit): Add output of many flags (Dynamic_Elab,
35776 Has_RACW, Is_Generic, etc.)
35777 (Output_Object, Gnatls): Take into account ALI files not attached to
35780 2004-03-22 Vincent Celier <celier@gnat.com>
35782 * gprep.adb: Change all String_Access to Name_Id
35783 (Is_ASCII_Letter): new function
35784 (Double_File_Name_Buffer): New procedure
35785 (Preprocess_Infile_Name): New procedure
35786 (Process_Files): New procedure
35787 (Gnatprep): Check if output and input are existing directories.
35788 Call Process_Files to do the real job.
35790 2004-03-22 Robert Dewar <dewar@gnat.com>
35792 * prj-env.adb, prj-nmsc.ads, prj-proc.ads,
35793 s-stache.ads, s-stache.adb: Comment updates. Minor reformatting.
35795 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
35797 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
35798 case when the source contains only comments.
35800 2004-03-22 Ed Schonberg <schonberg@gnat.com>
35802 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35803 declaration for a child subprogram body that acts as a spec, indicate
35804 that the entity in the declaration needs debugging information.
35806 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35807 full view if the subtype is created for a constrained record component;
35808 gigi has enough information to construct the record, and there is no
35809 place in the tree for the declaration.
35811 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35812 serial number for the dummy body that is built for analysis, to avoid
35813 inconsistencies in the generation of internal names when compiling
35816 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35818 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35821 2004-03-22 GNAT Script <nobody@gnat.com>
35823 * Make-lang.in: Makefile automatically updated
35825 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35827 * decl.c (gnat_to_gnu_entity): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
35828 * trans.c (tree_transform, emit_index_check): Likewise.
35829 * utils.c (build_template): Likewise.
35830 (max_size, convert): Remove handling of WITH_RECORD_EXPR.
35831 (maybe_unconstrained_array, unchecked_convert): Likewise.
35832 * utils2.c (gnat_truthvalue_conversion, build_binary_op): Likewise.
35833 (build_unary_op): Likewise.
35834 (compare_arrays, build_allocator): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
35835 (fill_vms_descriptor): Likewise.
35836 (build_call_alloc_dealloc): Likewise.
35838 * gigi.h (build_call_alloc_dealloc): Alignment is unsigned.
35840 2004-03-20 Joseph S. Myers <jsm@polyomino.org.uk>
35843 * gnat_ug.texi: Add info directory category and entry.
35844 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
35845 gnat_ug_wnt.texi: Regenerate.
35847 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
35849 * ada-tree.h: Update copyright notice.
35850 Minor reformatting.
35852 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35854 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35855 as regular exception objects and not as mere integers representing the
35856 condition code. The latter approach required some dynamics to mask off
35857 severity bits, which did not fit well into the GCC table based model.
35858 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35859 exception data objects. We don't it and it would conflict with the other
35860 external symbol we have to generate for such exceptions.
35862 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35863 the special code for VMS exceptions, since these are now represented
35864 as regular exceptions objects.
35866 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35868 * decl.c (debug_no_type_hash): Remove.
35869 (gnat_to_gnu_entity, case E_Array_Type): Don't set and clear it.
35870 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
35872 2004-03-19 Laurent Guerby <laurent@guerby.net>
35874 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35875 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35877 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35879 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35880 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35881 (TYPE_RM_SIZE_INT): Directly use type.values.
35882 (TREE_LOOP_ID): Clean up check.
35883 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35884 TYPE_VALUES, not TYPE_FIELDS.
35885 * trans.c (convert_with_check): Delay access of bounds of basetype
35886 until sure is numeric.
35888 2004-03-18 Arnaud Charlet <charlet@act-europe.fr>
35890 * 5atpopsp.adb: Remove RTEMS from list of platforms using this file.
35893 * 5ataprop.adb, 5ftaprop.adb, 5htaprop.adb, 5itaprop.adb, 5staprop.adb,
35894 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
35895 Specific.Set instead of direct call to e.g pthread_setspecific.
35897 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35899 * adaint.c: Update comments.
35901 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35902 GNATLIB_SHARED for FreeBSD.
35904 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35906 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35907 When needed (stack checking) the stack size is retrieved
35908 from the VxWorks kernel.
35910 * Makefile.in: Flag -nostdinc is required when building the run time
35911 for avoiding looking for files in the base compiler.
35912 Add the VxWorks specific version of the package body for
35913 System.Stack_checking.Operations (5zstchop.adb).
35915 * Make-lang.in: Add the object file for
35916 System.Stack_Checking.Operations.
35918 * Makefile.rtl: Add object file for the package
35919 System.Stack_Checking.Operations.
35921 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
35923 * s-stache.ads, s-stache.adb: Move the operations related to stack
35924 checking from this package to package System.Stack_Checking.Operations.
35925 This way, stack checking operations are only linked in the final
35926 executable when using the -fstack-check flag.
35928 2004-03-18 Doug Rupp <rupp@gnat.com>
35930 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
35933 * 5qsystem.ads, 5xcrtl.ads: New files.

35939 * prj-env.adb (Source_Paths, Object_Paths): New tables.
35940 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35941 the procedures Add_To_Path_File.
35942 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35943 making sure that each directory is present only once and, for object
35944 dirs, when a directory already present is added, the duplicate is
35945 removed and the directory is always put as the last in the table.
35946 Write the path files at the end of these accumulations.
35948 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35949 Files_Htable for all sources.
35951 * prj-proc.adb (Process): Remove restrictions between not directly
35952 related extending projects.
35954 2004-03-18 Emmanuel Briot <briot@act-europe.fr>

35957 (Find_Sources): Minor speed optimization.
35959 * prj-proc.ads, prj-proc.adb (Check, Recursive_Check, Process): New
35960 parameter Trusted_Mode.
35962 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35964 * scn.adb (Determine_License): Take into account a degenerated case
35965 when the source contains only comments.
35967 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35969 * sem_warn.adb (Check_References): For a warning on a selected
35970 component that does not come from source, locate an uninitialized
35971 component of the record type to produce a more precise error message.
35973 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35975 * 3zsoccon.ads: Fix multicast options.
35977 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35980 2004-03-15 Robert Dewar <dewar@gnat.com>
35982 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
35983 pragma used for a private type.
35985 * lib-xref.adb (Generate_Reference): Do not generate warning if
35986 reference is in a different unit from the pragma Unreferenced.
35988 * 5vtpopde.adb: Minor reformatting
35989 Fix casing of To_Task_ID
35991 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35992 flag if we have an unchecked conversion to an access type in the same
35995 2004-03-15 Geert Bosch <bosch@gnat.com>
35997 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35998 imaginary parts, use Double precision throughout.
36000 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
36001 we want to be able to compile run-time with -gnata for testing, but
36002 this may also be instantiated in user code that is compiled with -gnata.
36004 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
36006 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
36007 codes. Having a separate type for this is useful to enforce consistency
36008 throughout the various run-time units.
36009 (Exception_Data): Use Exception_Code for Import_Code.
36011 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
36012 Natural and Integer in various places.
36013 (Register_VMS_Exception): Use Base_Code_In to compute the exception code
36014 with the severity bits masked off.
36015 (Register_VMS_Exception): Handle the additional exception data pointer
36018 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
36019 component, now reflected by an exported accessor.
36020 (is_handled_by): New routine to compute whether the propagated
36021 occurrence matches some handler choice specification. Extracted out of
36022 get_action_description_for, and expanded to take care of the VMS
36024 (get_action_description_for): Use is_handled_by instead of an explicit
36025 complex condition to decide if the current choice at hand catches the
36026 propagated occurrence.
36028 * raise.h (Exception_Code): New type for C.
36030 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
36031 System.Standard_Library.Exception_Code, to allow references from the
36032 pragma import/export expander.
36034 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
36035 New accessors to allow easy access to GNAT exception data
36037 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
36038 redundant Handled_By_Others component, helper for the personality
36039 routine which will now be able to call the appropriate exception data
36042 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
36043 component of Standard_Exception_Type to be the closest possible to
36044 Exception_Code in System.Standard_Library, that we cannot get at this
36045 point. Expand a ??? comment to notify that this type node should
36046 probably be rewritten later on.
36048 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
36049 registration call to include a pointer to the exception object in the
36052 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
36053 instead of int and explicit bitmasks.
36055 2004-03-15 Vincent Celier <celier@gnat.com>
36057 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
36058 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
36060 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
36061 longer needed now that it is in the spec of
36062 System.Tasking.Task_Attributes.
36064 * adaint.h, adaint.c: (__gnat_create_output_file): New function
36066 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
36068 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
36070 * make.adb (Gnatmake): Do not check the executable suffix; it is being
36071 taken care of in Scan_Make_Arg.
36072 (Scan_Make_Arg): Add the executable suffix only if the argument
36073 following -o, in canonical case, does not end with the executable
36074 suffix. When in verbose mode and executable file name does not end
36075 with executable suffix, output the executable name, in canonical case.
36077 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
36078 to avoid warnings when instantiating Ada.Task_Attributes.
36081 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
36082 in the correct order.
36084 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
36085 redirect standard output and error to a file for the invocation of the
36086 compiler, then read the file.
36088 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
36089 directory, instead of the Value.
36090 (Find_Source_Dirs): Remove useless code & comments.
36092 2004-03-15 Ed Schonberg <schonberg@gnat.com>
36094 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
36095 tagged type is inherited, and the parent operation is not frozen yet,
36096 force generation of a freeze node for the inherited operation, so the
36097 corresponding dispatch entry is properly initialized.
36098 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
36099 when looking for user-defined equality operation.
36101 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
36102 boolean when locating primitive equality of tagged component.
36104 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
36105 bit-aligned field and the right-hand side a string literal, introduce
36106 a temporary before expanding assignment into a loop.
36108 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
36109 priority in full, to ensure that any expanded subepxressions of it are
36110 elaborated in the scope of the init_proc.
36112 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
36113 after object declaration, skipping over code that may have been
36114 generated for validity checks.
36116 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
36117 discriminants, ignore the known discriminants of its full view, if
36118 any, to check legality.
36120 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
36121 component if type has unknown discriminants.
36122 (Analyze_Private_Extension_Declaration): Discriminant constraint is
36123 null if type has unknown discriminants.
36125 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
36126 for end label when present.
36128 * s-fileio.adb (Open): When called with a C_Stream, use given name for
36129 temporary file, rather than an empty string.
36131 2004-03-15 Ed Falis <falis@gnat.com>
36133 * s-thread.adb: Removed, no longer used.
36135 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
36137 * decl.c (target.h): Now include.

37048 checks for bitfield creation are triggered.
37049 (finish_record_type): During last pass over the fields, clear
37050 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

37504 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate

37509 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37510 N_String_Literal node always references an E_String_Literal_Subtype
37511 entity. This may not be true in the future.
37512 (Possible_Bit_Aligned_Component): Move processing of
37513 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37515 * exp_ch6.adb (Expand_Thread_Body): Pick up

37520 (Type_May_Have_Bit_Aligned_Components): New function.

37560 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37561 ineffective elaborate all pragmas on non-visible packages (this
37562 happened when a renamed subprogram was called). Now the elaborate all
37563 always goes on the package containing the renaming rather than the one
37564 containing the renamed subprogram.
37566 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37567 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37592 * make.adb (Gnatmake): Special process for files to compile/check when
37593 -B is specified. Fail when there are only foreign mains in attribute

37628 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37629 all attributes, including read-only attribute.

37634 library naming scheme.

37668 checked when limited aggregates are implemented.

37671 pure, emit warning.

37781 * 5zinit.adb: Clean up.
37783 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37784 to __gnat_map_signal, imported from init.c to support
37785 signal -> exception mappings that depend on the vxWorks version.
37788 Created and exported __gnat_map_signal to support signal -> exception
37789 mapping that is dependent on the VxWorks version.

37818 Minor reformatting throughout
37820 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37822 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37823 bounds of a loop, create a separate block in order to generate proper
37824 cleanup actions to prevent memory leaks.
37826 * sem_res.adb (Resolve_Call): After a call to
37827 Establish_Transient_Scope, the call may be rewritten and relocated, in
37828 which case no further processing is needed.

37843 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37846 2003-12-08 Robert Dewar <dewar@gnat.com>
37848 * 7sintman.adb: Minor reformatting
37850 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37851 standard linker options to get standard libraries linked. We now plan
37852 to provide dummy versions of these libraries to match the appropriate
37853 configurable run-time (e.g. if a library is not needed at all, provide
37854 a dummy empty library).
37856 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37857 options (-L parameters and standard libraries). What we plan to do is
37858 to provide dummy libraries where the libraries are not required.
37860 * gnatbind.adb: Minor comment improvement
37862 2003-12-08 Javier Miranda <miranda@gnat.com>
37864 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

37872 of aggregate with default initialized components.
37873 (Has_Default_Init_Comps): Improve implementation to recursively check
37874 all the present expressions.
37876 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37877 to indicate that the initialization call corresponds to a
37878 default-initialized component of an aggregate.
37879 In case of default initialized aggregate with tasks this parameter is
37880 used to generate a null string (this is just a workaround that must be
37881 improved later). In case of discriminants, this parameter is used to
37882 generate a selected component node that gives access to the discriminant
37885 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37886 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37887 allocated aggregates with default-initialized components.
37889 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37890 the box notation is used in positional aggregates.

37932 Process nodes N_Comment.
37934 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37935 without comments and there are some comments, set the flag
37936 Unkept_Comments to True.
37937 (Scan): If there are comments, set the flag Unkept_Comments to True and
37938 clear the comments.
37939 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment

37969 (Set_Comment_As_Token): New procedure
37971 * sinput-p.adb: Update Copyright notice
37972 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

37977 * sem_aggr.adb: Add dependence on Exp_Tss package
37978 Correct typo in comment
37979 (Resolve_Aggregate): In case of array aggregates set the estimated
37980 type of the aggregate before calling resolve. This is needed to know
37981 the name of the corresponding IP in case of limited array aggregates.
37982 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37983 in case of default initialized array components.

38005 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
38006 they are automatically generated by Make-lang.in and cause nothing but
38007 maintenance troubles.
38009 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
38011 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

38025 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
38026 to ensure that the kernel fills in the interrupted context structure
38027 before calling a signal handler, which is necessary to be able to
38028 unwind past it. Update the copyright notice.
38030 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
38032 * a-elchha.ads: New file.

38117 included in HIE_NONE_TARGET_PAIRS.
38119 2003-12-03 Ed Schonberg <schonberg@gnat.com>
38122 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
38123 is legal in an instance, because legality is cheched in the template.
38126 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
38127 appplied to an unchecked conversion of a formal parameter.
38130 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

38280 between signals and interrupts.
38281 Add to Unblocked_Signal_Mask the set of signals that are in
38285 Adding a check to see whether the Interrupt_ID we want to unmask is in
38286 the range of Keep_Unmasked (in procedure Interrupt_Self_Process). The
38287 reason is that the index type of the Keep_Unmasked array is not always
38288 Interrupt_ID; it may be a subtype of Interrupt_ID.
38290 2003-11-24 Gary Dismukes <dismukes@gnat.com>
38293 (Remove_Side_Effects): Condition constantness of object created for a

41049 xtreeprs.adb: Correct statements in comments about maintainership
41052 2002-09-23 Zack Weinberg <zack@codesourcery.com>
41054 * Make-lang.in (EXTRA_GNATBIND_OBJS): Add version.o.
41055 * Makefile.in (TOOLS_LIBS): Add ../../version.o.
41056 * gnatvsn.ads: Gnat_Version_String is now a function.
41057 * gnatvsn.adb: New file. When asked for Gnat_Version_String,
41058 copy the C version_string into a String and return it.
41059 * gnatcmd.adb, gnatkr.adb, gnatlbr.adb, gnatlink.adb,
41060 gnatls.adb,gnatmake.adb, gnatprep.adb, gnatpsta.adb:
41061 Remove pragma Ident (Gnat_Version_String). If this was the
41062 sole use of package Gnatvsn, remove the with statement too.
41063 * gnat1drv.adb: Tweak -gnatv output.
41065 2002-09-17 Richard Henderson <rth@redhat.com>
41067 * trans.c (tree_transform): Use real_ldexp not REAL_VALUE_LDEXP.
41068 * config/dsp16xx/dsp16xx.md (fixuns_trunchfhi2): Use real_2expN.
41069 * config/mips/mips.md (fixuns_truncdfsi2): Likewise.
41070 (fixuns_truncdfdi2, fixuns_truncsfsi2, fixuns_truncsfdi2): Likewise.
41071 * config/m68k/m68k.c (floating_exact_log2): Use real_exponent
41072 and real_2expN instead of a loop.
41073 * doc/tm.texi (REAL_VALUE_LDEXP): Remove.
41074 (REAL_VALUE_RNDZINT, REAL_VALUE_UNSIGNED_RNDZINT): Remove.
41076 2002-08-25 Andre Leis <a.leis@gmx.net>
41077 David Billinghurst <David.Billinghurst@riotinto.com>
41079 * sysdep.c (__gnat_ttyname): include <termios.h> on cygwin
41081 2002-08-13 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
41083 * Make-lang.in (gnatbind$(exeext)): Link with $(SYSLIBS).
41084 Remove $(CONFIG_H) dependency.
41086 2002-08-08 Nathan Sidwell <nathan@codesourcery.com>
41088 * ada/Make-lang.in (ada.mostlyclean): Remove coverage files.
41090 2002-07-29 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
41092 * adadecode.c (ada_demangle): Use xstrdup in lieu of
41094 * misc.c (gnat_decode_option): Likewise.
41096 2002-07-15 Florian Weimer <fw@deneb.enyo.de>
41098 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41099 function approach did not work well because of a side effect (the
41100 function call could reallocate the table which was being indexed
41101 using its result). Fixes ada/4851. [RESURRECTED]

41676 * trans.c (tree_transform) [N_Loop_Statement]: Use
41677 expand_exit_loop_top_cond.

41695 (general) Add @./@: where approriate, and two spaces after the
41696 full stop at the end of a sentence. Use @samp markup when
41697 referring concrete lexical entities (keywords, attribute names
41698 etc.), and @syntax for ARM grammar elements. Use @r for English

41714 function approach did not work well because of a side effect (the
41715 function call could reallocate the table which was being indexed
41716 using its result). Fixes ada/4851.

42083 2001-12-17 Laurent Pautet <pautet@gnat.com>
42086 Fix comment of Shutdown_Socket and Close_Socket. These functions
42087 should not fail silently because if they are called twice, this
42088 probably means that there is a race condition in the user program.
42089 Anyway, this behaviour is consistent with the rest of this unit.

42244 reference nodes, since this field is used in such nodes.

43430 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43431 instead of simple checksum.
43432 (CRC_Match): new function.
43433 (CRC_Error): new constant.
43435 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43436 a CRC now and not a simple checksum. A CRC uses lower-case hex
43437 letters, fixes ambiguity in parsing.
43439 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43440 is what this variable will store.
43442 * bcheck.adb: Change reference to chechsum in comments by CRC.
43443 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43444 rename All_Checksum_Match to All_CRC_Match. Change due to API
43445 renaming since now GNAT does not use a simple checksum but a
43446 CRC using GNAT.CRC32.
43448 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43449 now and not anymore a simple checksum.

43486 Update comments for the CRC.
43488 * types.adb (Hex): Use lowercase for the letter part.
43490 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43491 for a word. This is currently used only for CRC. In previous version,
43492 the checksum was using a representation with all letter being
43493 upper-case. With the new implementation (using CRC) we do not remove
43494 the 32th bit of the CRC, so we can have an upper-case starting letter
43495 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43496 It is ambigous since the CRC was optional and could be followed by
43497 options like EB, EE. So now this routines uses lower-case letter for
43498 the hexadecimal representation. Strange enough only lower case letters
43499 where checked in Scan_ALI (even if this was not a possible case).
43501 * gnatvsn.ads (Library_Version): changed to 3.15a.
43503 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43506 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
