1742 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1743 Orig_Prev to Prev in the case where the actual is N_Function_Call or

3919 Is_Remote_Call_Interface to identify RACW types in a stable and
3920 consistent way. We used to rely in this predicate on the privateness of
3921 the designated type and its ancestors, but depending on the currently

3937 Add missing escaping of all-caps word 'CPP' in error messages.
3938 (Build_Discriminated_Subtype): Do not inherit representation clauses
3939 from parent type if subtype already carries them, because they are
3940 inherited earlier during derivation and already include those that may
3941 come from a partial view.

3979 operation of an RACW stub type (these primitives are only executed
3980 through dispatching, never through static calls).
3981 (Collect_Interps): When only one interpretation has been found, set N's
3982 Entity and Etype to that interpretation, otherwise Entity and Etype may
3983 still refer to an interpretation that was ignored by Add_One_Interp,
3984 in which case would end up with being marked as not overloaded but with
3985 an Entity attribute not pointing to its (unique) correct interpretation.

8244 subprogram body that acts as its own spec may not have a non-private
8245 WITH clause on a private sibling.
8246 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8247 child unit is a renaming, create an implicit with_clause on that
8248 parent, and not on the unit it renames, to prevent visibility errors

8295 of Related_Interface to Related_Type.
8296 (Record_Type_Declaration): Minor reordering of calls to decorate the

8308 (Find_Primitive_Operation): Handle case of class-wide types.
8309 (Analyze_Overloaded_Selected_Component): If type of prefix is
8310 class-wide, use visible components of base type.

8313 formal of a generic subprogram. find candidate interpretations by
8314 scanning the list of generic formal declarations.:
8315 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
8316 type from a limited_with_clause, and the full view is available, use it
8317 for subsequent semantic checks.

8319 (Find_Primitive_Operation): New function.
8320 (Analyze_Overloaded_Selected_Component): insert explicit dereference
8321 only once if several interpretations of the prefix yield an access type.

8345 Gary Dismukes <dismukes@adacore.com>
8347 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
8348 requeue statement is dispatching. Do not emit an error when the name is
8349 not an entry and the context is a dispatching select. Add code to
8350 perform subtype conformance between the formals of the current entry
8351 and those of the target interface primitive.
8352 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8353 Timed_Entry_Call): Analyze the triggering statement as the first step of
8354 the processing. If this is a dispatching select, postpone the analysis
8355 of all select statements until the Expander transforms the select. This
8356 approach avoids generating duplicate identifiers after the Expander has
8357 replicated some of the select statements. In case the Expander is
8358 disabled, perform regular analysis.
8359 (Check_Triggering_Statement): New routine.
8360 (Analyze_Requeue): Exclude any interpretations that are not entries when
8361 checking overloaded names in a requeue. Also test type conformance for

8930 Add Unreferenced and Warnings (Off) pragmas for cases of
8931 variables modified calls where they are IN OUT or OUT parameters and
8932 the resulting values are not subsequently referenced. In a few cases,
8933 we also remove redundant code found by the new warnings.

8951 * ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
8953 (Xref_Record): Change type for Line, since in the case of a reference to
8954 a predefined entity (as happens for array index types), the line is set
8956 Add support for parsing multiple array index types info, or
8957 multiple inherited interfaces info. This information cannot be stored
8958 in Xref_Entity_Record, which only supports a single instance of Tref_*,
8959 and is therefore stored in the list of references instead. It has a
8960 special treatement later on in tools that use this information.
8962 2007-10-15 Tristan Gingold <gingold@adacore.com>
8964 * debug.adb: Document use of -gnatd.a and -gnatd.I
8966 * layout.adb: On OpenVMS -gnatd.a disables alignment optimization.

8970 * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
8971 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
8972 care of access to class-wide interface types plus removal of bizarre
8973 conversion of tagged object to access type (reported by Gary
8974 Dismukes). After this patch there is no need to perform any
8975 additional management on these nodes in Expand_Interface_Actuals.
8977 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
8978 that handles use of 'Access and 'Unchecked_Access applied to
8979 actuals covering interface types. Such code is now
8980 centralized in Expand_N_Attribute_Reference.
8982 2007-10-15 Ed Schonberg <schonberg@adacore.com>
8984 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
8985 of tagged types whose ultimate ancestor is a CPP type.
8986 (Freeze_Array_Type): For a packed array type, generate an initialization
8987 procedure if the type is public, to handle properly a client that
8988 specifies Normalize_Scalars.
8990 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
8992 * exp_ch9.adb (Actual_Index_Expression): When the expansion occurs
8993 inside a generic body, retrieve the full view of the entry family

9010 (passing'Unrestricted_Access of nested subprograms to Sort) with use of
9011 the generic Heap_Sort_G, in order to avoid trampolines.
9013 2007-10-15 Vasiliy Fofanov <fofanov@adacore.com>
9014 Jose Ruiz <ruiz@adacore.com>
9016 * vx_stack_info.c: New file.
9018 * i-forbla-unimplemented.ads: New file.
9020 * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
9021 for unsupported configurations; use it on VMS targets instead of the
9023 (EXTRA_LIBGNAT_SRCS,EXTRA_LIBGNAT_OBJS for VxWorks): Include
9024 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9025 used by VxWorks targets to have access to task-specific data and be
9026 able to extract the stack boundaries for stack checking.
9027 Use system-vms-ia64.ads on ivms.
9029 * Make-lang.in: Update dependencies.
9031 * sysdep.c (__gnat_get_stack_info): Move to a standalone file

9048 95 reserved word in its name.
9049 (Process_Project_Level_Array_Attributes): Process new attribute
9050 Runtime_Library_Dir.
9052 * prj-part.adb (Parse_Single_Project): Do not check the name of the
9053 config project against the user project names.

9068 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9070 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9071 association for an access component, add an association with null as
9072 the expression. Remove testing for array subtypes and the setting in
9073 that case of Ctyp to the array component type, which prevented proper
9074 inclusion of an association for null-initialized arrays. Collapse
9075 condition that tests for array subtypes into just a test of
9076 Is_Partially_Initialized_Type (which already covers arrays anyway).
9078 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>

9085 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9087 * sem_ch3.adb (Build_Derived_Concurrent_Type): Set the Is_Constrained
9088 flag of derived concurrent types, taking into account the flag setting
9089 on the parent subtype and any new set of discriminants.
9091 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9093 * sem_ch4.adb: Minor code and comment reformatting.
9094 (Analyze_Allocator): When the designated type of an unconstrained
9095 allocator is a record with unknown discriminants or an array with
9096 unknown range bounds, emit a detailed error message depending on the
9097 compilation mode and whether the designated type is limited.

9151 * gnat_ugn.texi: Add documentation for switches --version and --help
9152 for the GNAT tools gnatbind, gnatlink, gnatmake, gnatchop, gnatname,
9153 gnatxref, gnatfind, gnatls, and gnatclean.

9168 * g-soccon-vms.ads: Fix value of MSG_WAITALL.
9171 Update documentation to note that OpenVMS 8.3 or later must be used
9172 to generate g-soccon-vms.ads.
9174 * atree.adb: Add ??? comment
9176 * exp_util.adb: Minor reformatting.

9226 (gigi): Rename and change type of number_units parameter, change
9227 type of file_info_ptr parameter.
9228 * trans.c (number_files): New global variable.
9229 (gigi): Rename and change type of number_units parameter, change
9230 type of file_info_ptr parameter.
9231 If mapped location support is enabled, create the isomorphic mapping
9232 between source files and line maps.
9233 (Sloc_to_locus): If mapped location support is enabled, translate
9234 source location into mapped location.
9235 (annotate_with_node): Rename into set_expr_location_from_node.
9236 Call set_expr_location instead of annotate_with_locus.
9237 (Pragma_to_gnu): Adjust for above change.

9249 (Applicable_Use): Emit a warning when a package tries to use itself.
9250 (Use_One_Type): Add variable Is_Known_Used. Emit a warning when a type

9252 declared in the current package.
9253 (Spec_Reloaded_For_Body): New subsidiary routine for Use_One_Type.
9255 * a-tasatt.adb, s-osprim-vxworks.adb, g-socthi-mingw.adb,

9259 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9261 * a-calend-vms.adb, a-calend.adb:
9262 Add a section on leap seconds control along with two entities used to
9263 enable and disable leap seconds support. The array Leap_Second_Times is
9264 now constant and contains hard time values pre-generated. Remove
9265 all elaboration code used to populate the table of leap seconds.
9268 Add entity Leap_Seconds_Support to the list of global run-time variables
9269 along with a comment on its usage and values.
9270 (Gen_Adainit_Ada): Add code to generate the declaration and import of

9298 2007-09-26 Olivier Hainque <hainque@adacore.com>
9300 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
9301 #include <utime.h> and #define GCC_RESOURCE_H before

9303 Add more protections in __gnat_translate_vms.
9305 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before

9311 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
9313 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9316 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9318 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9321 * sem_dist.ads: Minor comment fix
9323 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9325 2007-09-26 Javier Miranda <miranda@adacore.com>
9326 Eric Botcazou <ebotcazou@adacore.com>
9329 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9330 indirection added to the HT_Link component of the TSD. This is required
9331 to statically allocate the TSD.
9334 Minor reordering of the declarations in the private part. Required to
9335 add a level of indirection to the contents of the TSD component HT_Link.
9336 This is required to statically allocate the TSD.
9338 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9339 Is_Statically_Allocated set from constant objects.
9340 Do not make exported constants created by the compiler volatile.
9341 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9344 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9345 before returning them.

9348 public part of the package.
9349 (Make_DT): Move HT_Link component out of the TSD record. For this
9350 purpose Make_DT now declares a separate object that stores the
9351 HT_Link value, and initializes the TSD component with the address
9352 of this new object. The addition of this level of indirection is
9353 required to statically allocate the TSD because the TSD cannot
9354 have variable components.
9355 (Expand_Interface_Conversion): Improve the expanded code.
9356 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9358 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9359 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9360 if we are building static dispatch tables then we must not generate
9361 extra code to register the primitive because the dispatch table will
9362 be built at the end of the library package; otherwise we notify that
9363 we cannot build the static dispatch table.
9365 2007-09-26 Robert Dewar <dewar@adacore.com>
9367 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9372 missing component clause.
9373 (Analyze_Attribute_Definition_Clause, case Address): Apply the special
9374 tests for controlled type overlay to composites with controlled
9376 (Analyze_Record_Representation_Clause): Add reference for component name
9378 2007-09-26 Javier Miranda <miranda@adacore.com>

9381 * einfo.adb (Is_Thunk): New attribute applicable to subprograms. True
9382 for thunks associated with interface types.
9384 * einfo.ads: Improve documentatation of Is_Internal
9385 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9386 associated with interface types.
9387 Extensive comment fixes regarding flags that appear in all entities. The
9388 documentation is now consistent for all such flags (there were a number
9389 of errors in the documentation in this regard).
9391 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9393 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9394 of these procedures are passed a function call that already has
9395 build-in-place actuals (testing new flag
9396 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9397 the case where processing continues.
9398 (Expand_Call): If the call is generated from a thunk body then we
9399 propagate the extra actuals associated with the accessibility
9400 level of the access type actuals.
9402 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9403 of each extra formal of a protected operation to reference the
9404 corresponding extra formal of the subprogram denoted by the
9405 operation's Protected_Body_Subprogram.
9407 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9408 N_Function_Call nodes.
9410 2007-09-26 Robert Dewar <dewar@adacore.com>
9412 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9414 * debug.adb: Add d.s flag.
9416 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9418 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9419 debug variable so that it won't be initialized when pragma
9420 Initialize_Scalars is in effect.
9422 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9424 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9425 initialization of a full view. This is moved to
9426 Analyze_Package_Specification.
9428 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9429 preelaborable initialization of a full view in entity loop.
9430 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9431 its child units are use-visible only if they are visible child units.
9433 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9434 whether an expression can be used within a type declaration that
9435 requires preelaborable init.
9436 (Check_Components): Replace inline code that does partial checking for
9437 preelaborable default expressions with call to
9438 Is_Preelaborable_Expression.
9439 (Has_Preelaborable_Initialization): In the case of a generic actual
9440 subtype, (that is, Is_Generic_Actual is True), return the result of
9441 applying Has_Preelaborable_Initialization to the generic actual's base
9444 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9446 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a

9448 (Is_Leap): Move the routine to the scope of Week_In_Year.
9449 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9450 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9451 avoids calling Time_Of and Split, thus making it more efficent.
9452 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9454 * g-calend.ads (Week_In_Year): Change comment to reflect new
9457 2007-09-26 Emmanuel Briot <briot@adacore.com>
9459 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9460 Command_Line): New types
9461 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9462 support for defining how switches can be grouped on a command line (as
9463 is the case for -gnatw... for GNAT), and how simple switches can be
9464 used as aliases for more complex switches (-gnatwa is same as
9466 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9467 (Start, Current_*): New subprograms
9468 Added support for parsing an array of strings in addition to the real
9470 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9471 be moved from the body to the private part of the spec.
9472 (*): All subprograms now have an extra parameter with default value to
9473 specify which parser should be used. For backward compatibility, it
9474 defaults to parsing the command line of the application. They were also
9475 modified to properly handle cases where each of the argument does not
9476 start at index 1 (which is always true for Ada.Command_Line, but not
9477 when processing any Argument_List).
9478 (Free): New subprogram
9479 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9480 Argument): New subprograms
9481 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9482 special characters like ':', '=',... are now handled in a single place,
9483 which makes the code more extensible eventually.
9484 (Getopt, Full_Switch): When the switch was returned as part of the
9485 special character '*', make sure it is prepended by the switch character
9486 ('-' in general), so that the application knows whether "foo" or "-foo"
9487 was specified on the command line.
9489 2007-09-26 Florian Villoing <villoing@adacore.com>
9491 * g-dirope.adb (Remove_Dir): In case we are removing directories
9492 recursively, make sure that if an exception is raised during the
9493 processing, the current working directory is reset to its initial
9494 value before propagating the exception.
9496 2007-09-26 Vincent Celier <celier@adacore.com>
9498 * gnatbind.adb: If there are several ALI files specified and there is
9499 a main program to bind, the first ALI is expected to contain the main
9500 subprogram and the names of the binder generated files will be derived
9501 from the first ALI file name.
9502 (Gnatbind): Fix insertion character in invocation of Error_Msg
9504 2007-09-26 Vincent Celier <celier@adacore.com>
9506 * gnatcmd.adb (Check_Files): Do not include sources that have been
9507 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9509 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9511 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9512 information about each of its index types, following the type
9513 reference for its component type.
9515 2007-09-26 Vincent Celier <celier@adacore.com>
9517 * make.adb: (Kill): New procedure (__gnat_kill imported)

9528 2007-09-26 Vincent Celier <celier@adacore.com>
9530 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9532 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9533 Replace components Compiler_Min_Options and Binder_Min_Options with
9534 Compiler_Required_Switches and Binder_Required_Switches in record

9539 * prj-attr.adb: New attributes Required_Switches (<language>) in
9540 packages Compiler and Binder.
9542 * prj-nmsc.adb: Major rewrite of the processing of configuration
9543 attributes for gprbuild. No impact on GNAT tools.
9545 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9546 process configuration attributes: this is done in Prj.Nmsc.Check.
9547 (Recursive_Process): Make a full copy of packages inherited from project
9548 being extended, instead of a shallow copy.
9549 (Process_Project_Tree_Phase_1): New procedure
9550 (Process_Project_Tree_Phase_1): New procedure
9551 (Process): Implementation now uses the two new procedures
9553 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9554 from the project config, not the tree config that no longer exists.
9556 2007-09-26 Vincent Celier <celier@adacore.com>

9580 ancestor of the derived type, the operations are inherited from the
9581 primary dispatch table of the parent.
9582 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9583 when the context is an explicit type conversion.

9880 Thomas Quinot <quinot@adacore.com>
9882 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
9883 create an abstract subprogram in the case of 'Input. For 'Output we now
9884 create a real spec/body when the type is abstract, since it can
9885 potentially be called.
9886 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9887 body for 'Output when the type is abstract (only the creation of the
9888 body for 'Input is excluded when the type is abstract).
9889 (Stream_Operation_OK): Add an additional condition in the return
9890 statement, so that False will be returned for TTS_Stream_Input if the
9891 associated tagged type is an abstract extension. Add comments for
9893 (Expand_N_Object_Declaration): For the case of a shared passive
9894 variable, insert init proc call only after the shared variable
9895 procedures have been processed, because the IP call needs to undergo
9896 shared passive variable reference expansion, which requires these
9897 procedures to be available (and elaborated).
9899 2007-09-10 Vincent Celier <celier@adacore.com>
9901 * prj-env.ads, prj-env.adb (Create_Mapping_File (Language)): Remove
9902 parameter Runtime_Project.
9904 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9906 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
9907 given a box association, the type of the component is discriminated,
9908 and the value of the discriminant is the discriminant of the enclosing
9909 type, retrieve its value from the aggregate itself, where it must have
9912 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
9913 to remove other spurious ambiguities on arithmetic operations involving
9914 literals and addresses, on systems where Address is a visible integer
9915 type, when the operator is called in functional notation.
9916 (Try_Primitive_Operation): Within an instance, a call in prefixed form
9917 is legal when the types match, even if the operation is currently
9920 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9922 * sem_ch12.adb (Build_Local_Package): A formal package with no
9923 associations is legal if all formals have defaults. It is not
9924 equivalent to a formal declared with a box.

10035 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10037 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the

10041 (Is_Raised, Set_Is_Raised): Bodies of new routines.
10042 (Write_Entity_Flags): Write the status of flag Is_Raised.
10043 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10044 spurious ambiguities when integer literals appear in the context of an
10045 address type that is a visible integer type.
10047 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10048 exceptions never being raised.
10049 (Analyze_Raise_Statement): When analyzing an exception, mark it as being
10052 2007-08-31 Javier Miranda <miranda@adacore.com>
10054 * exp_ch11.adb (Expand_At_End_Handler): Avoid generation of raise
10055 statement when compiling under restriction No_Exceptions_Proparation.

10059 * exp_ch3.adb (Build_Record_Init_Proc): If there is a static
10060 initialization aggregate for the type, generate itype references for
10061 thetypes of its (sub)components, to prevent out-of-scope errors in gigi.
10063 2007-08-31 Gary Dismukes <dismukes@adacore.com>
10065 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10066 library-level package renaming, pass the declaration associated with
10067 the renaming's special debug variable to Qualify_Entity_Names to ensure
10068 that its encoded name is properly qualified.
10070 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10071 occurring in the list of entities to qualify, and do not attempt to
10072 traverse an entity list in that case. Variables associated with
10073 ` library-level package renamings can now occur in the table.
10075 * exp_dbug.ads: Revise documentation of the encoding for renaming
10078 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

10081 access type points to an unconstrained array.
10083 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10085 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
10088 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect
10089 simple redundant qualifications. The check is performed whenever the
10090 expression is a non-overloaded identifier.
10091 (Resolve_Type_Conversion): Enchance the redundant type conversion check
10092 to include loop parameters.
10093 (Valid_Conversion): Avoid generation of spurious error message.

10097 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10098 concatenations of string literals into a single literal, in order to
10099 avoid very deep recursion in the front end, which was causing stack
10102 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10103 string, and the right operand is a string literal (the case of "" &
10104 "..."), optimize by avoiding copying the right operand -- just use the
10105 value of the right operand directly.
10107 * stringt.adb (Store_String_Chars): Optimize by growing the
10108 String_Chars table all at once, rather than appending characters one by
10110 (Write_String_Table_Entry): If the string to be printed is very long,
10111 just print the first few characters, followed by the length. Otherwise,
10112 doing "pn(n)" in the debugger can take an extremely long time.
10114 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10115 Store_String_Char with Store_String_Chars.
10117 2007-08-31 Vincent Celier <celier@adacore.com>

10130 have not been fully analyzed.
10132 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10134 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10135 flag, for effiency. It is called when analyzing arithmetic operators
10136 and also for actuals in calls that are universal_integers. The flag is
10137 set for the predefined type address, and for any type or subtype
10140 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10141 Universal_Integer, when the formal is a descendent of address and the
10142 call appears in user code.
10143 (Analyze_Selected_Component): if the prefix is a private extension, the
10144 tag component is visible.
10146 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an

10207 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10209 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10210 associated with Standard_Debug_Renaming_Type, to be used as the type of
10211 the special variables whose names provide debugger encodings for
10212 renaming declarations.
10214 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10215 (Set_Debug_Renaming_Link): Change to set Node25.
10216 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
10217 (Write_Field25_Name): Add case for E_Variable to output
10218 "Debug_Renaming_Link".
10219 (Write_Field23_Name): Correct the output string for "Limited_View".
10221 * exp_dbug.adb: Add with and use of Tbuild.
10222 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10223 and literal with creation of a variable of type
10224 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10225 and the entity of the renaming declaration.
10226 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10227 part of the name of a variable that has a Debug_Renaming_Link.
10229 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10230 special type to be associated with variables that provide debugger
10231 encodings for renaming declarations.

10234 Ed Schonberg <schonberg@adacore.com>
10235 Javier Miranda <miranda@adacore.com>
10237 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10238 ancestor part given by an aggregate to test for an unchecked conversion,
10239 since this can occur in some cases when the ancestor part is a function
10240 call, and we don't want to fall into the recursive call to this
10241 procedure in that case.
10243 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10244 stream attributes on limited types to account for user-specified
10245 attributes as well as whether Input (resp. Output) becomes available
10246 due to Read (resp. Write) being available for the type. Change Boolean
10247 variable to the more accurate name
10248 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10249 double-"not" predicate at beginning of return statement to more
10250 understandable form.
10252 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10253 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10254 in a block statement and use that as the first statement of the
10255 expanded return rather than incorrectly using the handled sequence as
10256 the first statement.
10258 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10259 operation, generate an explicit freeze node for it rather than
10260 generating extra formals, to ensure that gigi has the proper order of
10261 elaboration for anonymous subtypes in the signature of the subprograms.
10262 (Build_In_Place_Formal): Move assertion to beginning of loop.
10263 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10264 applied to a function call (occurs for some cases of 'Input).
10265 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
10266 applied to a function call (occurs for some cases of 'Input).
10268 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10269 2005, generate an extended return statement enclosing the result object
10272 * freeze.adb (Freeze_Record_Type): Extend the current management of
10273 components that are access type with an allocator as default value: add
10274 missing support to the use of qualified expressions of the
10275 allocator (which also cause freezing of the designated type!)
10276 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10277 dispatching operation, since extra formals may be needed by calls to
10278 build-in-place functions (such as stream 'Input).
10280 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10281 formals for 'Constrained and accessibility level in the case of a
10282 predefined dispatching operation.
10284 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10285 point, no need to find the parent node.
10287 2007-08-16 Javier Miranda <miranda@adacore.com>
10289 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10290 and entry barriers.
10292 2007-08-16 Javier Miranda <miranda@adacore.com>
10294 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10295 is not really required and can introduce regression with the debugger.
10296 The original problem is fixed with the patch written for checks.adb.
10298 2007-08-16 Thomas Quinot <quinot@adacore.com>
10300 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
10301 Range_Check on Allocated_Table.
10303 2007-08-16 Vincent Celier <celier@adacore.com>
10305 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
10306 Including_Non_Switch set to False.
10307 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10308 Including_Non_Switch set to False.
10310 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10311 parameter Including_Non_Switch, defaulted to True. When
10312 Including_Non_Switch is False, options that are not switches and
10313 appear as relative path are not converted to absolute paths.

10328 from the immediate ancestor of Main_Unit_Entity.
10329 (Install_Limited_Withed_Unit): Do not install the limited view of
10330 package P if P is reachable through an ancestor chain from package C

10337 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10338 generic for an enclosing instance is a global reference, even though
10339 its scope is the enclosing instance.

10365 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10366 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10367 the statement which is being resolved comes from a predefined library
10368 unit, all non-predefined library interpretations are skipped.
10369 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10370 but the "&" is user defined, give an error, because the folding would

10374 the parser has folded a long sequence of concatenations of string
10377 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10378 and "JMP_BUF" variables as artificial.
10379 (N_String_Literal): Do not use alloca for very long string literals. Use
10380 xmalloc/free instead. Otherwise the stack might overflow.

10425 Ed Schonberg <schonberg@adacore.com>
10427 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10428 Suppress unmodified in-out parameter warning in some cases
10429 This patch is a also fairly significant change to the way suppressible
10430 checks are handled.
10432 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10433 needed for access to concurrent record types generated by the expander.
10434 (Generate_Range_Check): When generating a temporary to capture the
10435 value of a conversion that requires a range check, set the type of the
10436 temporary before rewriting the node, so that the type is always
10437 properly placed for back-end use.
10438 (Apply_Float_Conversion_Check): Handle case where the conversion is
10440 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10441 for a protected type in order to examine its discriminants.

10448 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10449 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10450 tests optimized out.
10452 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10453 (Get_Allocator_Final_List): For the case of an anonymous access type
10454 that has a specified Associated_Final_Chain, do not go up to the
10456 (Expand_N_Type_Conversion): Test for the case of renamings of access
10457 parameters when deciding whether to apply a run-time accessibility
10459 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10460 aggregate code before allocator, and ahead of declaration for
10461 temporary, to prevent access before elaboration when the allocator is
10462 an actual for an access parameter.
10463 (Expand_N_Type_Conversion): On an access type conversion involving an
10464 access parameter, do not apply an accessibility check when the
10465 operand's original node was an attribute other than 'Access. We now
10466 create access conversions for the expansion of 'Unchecked_Access and
10467 'Unrestricted_Access in certain cases and clearly accessibility should
10468 not be checked for those.
10470 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10471 includes a type conversion of a packed component that has been expanded,
10472 recover the original expression for the object, and use this expression
10473 in the post-call assignment statement, so that the assignment is made
10474 to the object and not to a back-end temporary.
10475 (Freeze_Subprogram): In case of primitives of tagged types not defined
10476 at the library level force generation of code to register the primitive
10477 in the dispatch table. In addition some code reorganization has been
10478 done to leave the implementation clear.
10479 (Expand_Call): When expanding an inherited implicit conversion,
10480 preserve the type of the inherited function after the intrinsic
10481 operation has been expanded.
10483 * exp_ch2.ads, exp_ch2.adb
10484 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10485 of an entry formal appearing in an assignment statement does not assign
10487 (Expand_Current_Value): Instead of calling a routine to determine
10488 whether the prefix of an attribute reference should be optimized or
10489 not, prevent the optimization of such prefixes all together.
10491 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10492 component whose prefix is known to be of an access type is an implicit
10493 dereference and does not assign to the prefix.
10495 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10496 Robert Dewar <dewar@adacore.com>
10498 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10499 itype is visited, make an entry into table to link associated node and
10501 Add comments and correct harmless error in Build_NCT_Hash_Tables
10502 (Array_Aggr_Subtype): Associate each itype created for an index type to
10503 the corresponding range construct, and not to the aggregate itself. to
10504 maintain a one-to-one correspondence between itype and its associated
10505 node, to prevent errors when complex expression is copied.
10506 Fix mishandling of multiple levels of parens
10508 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10509 treatment of limited views uniform for all visible declarations in a
10510 limited_withed package.
10511 (New_Copy_Tree): If hash table is being used and itype is visited,
10512 make an entry into table to link associated node and new itype.
10513 (Resolve_Record_Aggregate): Do not add an others box association for a
10514 discriminated record component that has only discriminants, when there
10515 is a box association for the component itself.
10517 * par-ch4.adb: Fix mishandling of multiple levels of parens
10519 2007-08-14 Robert Dewar <dewar@adacore.com>

10553 Gary Dismukes <dismukes@adacore.com>
10555 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
10556 to make treatment of limited views uniform for all visible declarations
10557 in a limited_withed package.
10558 Improve warnings for in out parameters
10559 (Set_Related_Interaface/Related_Interface): Allow the use of this
10560 attribute with constants.
10561 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10562 Warn on duplicate pragma Preelaborable_Initialialization
10564 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10565 generation of a freezing node to ensure proper management of null
10566 excluding access types in the backend.
10567 (Create_Extra_Formals): Test base type of the formal when checking for
10568 the need to add an extra accessibility-level formal. Pass the entity E
10569 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10570 originally being done in a couple of cases), to ensure that the
10571 Extra_Formals list gets set on the entity E when the first entity is
10573 (Conforming_Types): Add missing calls to Base_Type to the code that
10574 handles anonymous access types. This is required to handle the
10575 general case because Process_Formals builds internal subtype entities
10576 to handle null-excluding access types.
10577 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10578 functions that need it, even when not marked Requires_Overriding.
10579 Improve warnings for in out parameters
10580 (Analyze_Function_Return): Warn for disallowed null return
10581 Warn on return from procedure with unset out parameter
10582 Ensure consistent use of # in error messages
10583 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10584 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10585 the implicit conversion of the expression done for anonymous access
10586 types. This is required to generate the code of the null excluding
10587 check (if required).
10589 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10590 A formal parameter is never publicly referenceable outside of its body.
10591 (Check_References): For an unreferenced formal parameter in an accept
10592 statement, use the same warning circuitry as for subprogram formal
10594 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10595 Output_Unreferenced_Messages, containing the part of that routine that
10596 is now reused for entry formals as described above.
10597 (Goto_Spec_Entity): New function
10598 (Check_References): Do not give IN OUT warning for dispatching operation
10599 Improve warnings for in out parameters

10607 Gary Dismukes <dismukes@adacore.com>
10609 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10610 (Expand_N_Attribute_Reference): Further unify the handling of the
10611 three forms of access attributes, using common code now for all three
10612 cases. Add a test for the case of applying an access attribute to
10613 an explicit dereference when the context is an access-to-interface
10614 type. In that case we need to apply the conversion to the prefix
10615 of the explicit dereference rather than the prefix of the attribute.
10616 (Attribute_Version, UET_Address): Set entity as internal to ensure
10617 proper dg output of implicit importation.
10618 (Expand_Access_To_Type): Removed.
10619 (Expand_N_Attribute_Reference): Merge the code from the three cases
10620 of access attributes, since the processing is largely identical for
10621 these cases. The substantive fix here is to process the case of a
10622 type name prefix (current instance case) before handling the case
10623 of interface prefixes.

10628 Robert Dewar <dewar@adacore.com>
10630 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10631 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10632 type that is an anonymous access to controlled object, establish
10633 an associated finalization chain to avoid corrupting the global
10634 finalization list when a dynamically allocated object designated
10635 by such a component is deallocated.
10636 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10637 functions that need it, even when not marked Requires_Overriding.
10638 (Initialize_Tag): Replace call to has_discriminants by call to
10639 Is_Variable_Size_Record in the circuitry that handles the
10640 initialization of secondary tags.
10641 (Is_Variable_Size_Record): New implementation.
10642 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10643 Suppress_Initialization pragma for a derived type.
10644 (Is_Variable_Size_Record): New subprogram.
10645 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10646 initial version of this routine and also fixes problems causing
10647 incomplete initialization of the table of interfaces.
10648 (Build_Init_Procedure): Improve the generation of code to initialize the
10649 the tag components of secondary dispatch tables.
10650 (Init_Secondary_Tags): New implementation that simplifies the previous
10651 version of this routine.
10652 (Make_DT): Add parameter to indicate when type has been frozen by an
10653 object declaration, for diagnostic purposes.
10654 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10655 diagnose attemps to freeze a subprogram when some untagged type of its
10656 profile is a private type whose full view has not been analyzed yet.
10657 (Freeze_Array_Type): Generate init proc for packed array if either
10658 Initialize or Normalize_Scalars is set.
10659 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10660 constructing the new profile, copy the null_exclusion indicator for each
10661 parameter, to ensure full conformance of the new body with the spec.
10663 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10664 Create wrappers for constructor functions that need it, even when not
10665 marked Requires_Overriding.
10666 (Covers): Handle properly designated types of anonymous access types,
10667 whose non-limited views are themselves incomplete types.
10668 (Add_Entry): Use an entity to store the abstract operation which hides
10670 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10671 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10672 initialization aggregate.
10673 (Function_Interp_May_Be_Hidden): Rename to
10674 Function_Interp_Has_Abstract_Op.
10675 (Has_Compatible_Type): Remove machinery that skips interpretations if
10676 they are labeled as potentially hidden by an abstract operator.
10677 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10678 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10679 (Write_Overloads): Output the abstract operator if present.
10680 (Add_Entry): Before inserting a new entry into the interpretation table
10681 for a node, determine whether the entry will be disabled by an abstract
10683 (Binary_Op_Interp_May_Be_Hidden): New routine.
10684 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10686 (Function_Interp_May_Be_Hidden): New routine.
10687 (Has_Compatible_Type): Do not consider interpretations hidden by
10688 abstract operators when trying to determine whether two types are
10690 (Has_Hidden_Interp): New routine.
10691 (Set_May_Be_Hidden_Interp): New routine.
10692 (Write_Overloads): Write the status of flag May_Be_Hidden.

10697 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
10698 types declared in the declarative part of a nested package body or in
10699 the proper body of a stub.
10700 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10701 of the same dispatch table slot to renamed primitives.
10702 (Make_Select_Specific_Data_Table): Handle private types.
10703 (Tagged_Kind): Handle private types.
10704 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10705 output of implicit importation and exportation.
10706 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10707 first formal of the thunk is always associated with the controlling
10708 type. In addition perform the following code cleanup: remove formal
10709 Thunk_Alias which is no longer required, cleanup evaluation of the
10710 the controlling type, and update the documentation.
10711 Replace occurrence of Default_Prim_Op_Count by
10712 Max_Predef_Prims. Addition of compile-time check to verify
10713 that the value of Max_Predef_Prims is correct.
10714 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10715 (Make_DT): Add parameter to indicate when type has been frozen by an
10716 object declaration, for diagnostic purposes.
10717 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10718 construction of statically allocated dispatch tables.
10719 (Make_DT): In case of library-level tagged types export the declaration
10720 of the primary tag. Remove generation of tags (now done by Make_Tags).
10721 Additional modifications to handle non-static generation of dispatch
10722 tables. Take care of building tables for asynchronous interface types
10723 (Make_Tags): New subprogram that generates the entities associated with
10724 the primary and secondary tags of Typ and fills the contents of Access_
10725 Disp_Table. In case of library-level tagged types imports the forward
10726 declaration of the primary tag that will be declared later by Make_DT.
10727 (Expand_Interface_Conversion): In case of access types to interfaces
10728 replace an itype declaration by an explicit type declaration to avoid
10729 problems associated with the scope of such itype in transient blocks.

10732 Ed Schonberg <schonberg@adacore.com>
10733 Javier Miranda <miranda@adacore.com>
10735 * exp_util.ads, exp_util.adb:
10736 This patch replaces a number of occurrences of explicit tests for N_Null
10737 with calls to Known_Null. This improves tracking of null values, since
10738 Known_Null also catches null constants, and variables currently known to
10739 be null, so we get better tracking.
10740 (Ensure_Defined): create an itype reference only in the scope of the
10742 (Side_Effect_Free): A selected component of an access type that
10743 denotes a component with a rep clause must be treated as not
10744 side-effect free, because if it is part of a linked structure its
10745 value may be affected by a renaming.
10746 (Expand_Subtype_From_Expr): For limited objects initialized with build
10747 in place function calls, do nothing; otherwise we prematurely introduce
10748 an N_Reference node in the expression initializing the object, which
10749 breaks the circuitry that detects and adds the additional arguments to
10750 the called function. Bug found working in the new patch for statically
10751 allocated dispatch tables.
10752 (Is_Library_Level_Tagged_Type): New subprogram.
10753 (Remove_Side_Effects): If the expression of an elementary type is an
10754 operator treat as a function call.
10755 (Make_Literal_Range): If the index type of the array is not integer, use
10756 attributes properly to compute the constraint on the resulting aggregate
10759 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10760 class-wide type whose base type is an incomplete private type, leave
10761 class-wide type unfrozen so that freeze nodes can be generated
10762 properly at a later point.
10763 (Freeze_Entity, array case): Handle case of pragma Pack and component

11392 (Set_Item): When the new item is an element of the currently allocated
11393 table passed by reference, save a copy on the stack if we're going
11394 to reallocate. Also, in Table.Set_Item, make sure we test the proper
11395 variable to determine whether to call Set_Last.

11408 Thomas Quinot <quinot@adacore.com>
11410 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11411 derived type with interface progenitors use the analyzed formal as the
11412 parent of the actual, to create renamings for all the inherited
11413 operations in Derive_Subprograms.
11414 (Collect_Previous_Instances): new procedure within of
11415 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11416 unit being loaded, to ensure that the generation of global symbols is
11417 consistent in different compilation modes.
11418 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11419 takes progenitor types into account.
11420 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11421 traversing over the primitives of the formal and actual types to locate
11422 any abstract subprograms of the actual type that correspond to a
11423 nonabstract subprogram of the formal type's ancestor type(s), and issue
11424 an error if such is found.
11425 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11426 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11427 Remove bogus guard around calls to Inherit_Context.
11428 (Reset_Entity): If the entity is the selector of a selected component
11429 that denotes a named number, propagate constant-folding to the generic
11430 template only if the named number is global to the generic unit.
11431 (Set_Instance_Env): Only reset the compilation switches when compiling
11432 a predefined or internal unit.
11434 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11436 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
11437 parameter to determine whether operation applies to the prefix.
11438 (Complete_Object_Operation): If actual has an access type and
11439 controlling formal is not an in_parameter, reject the actual if it is
11440 an access_to_constant type.
11441 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11442 type, the candidate operations are found in the scope of declaration of
11443 the type, because the type has no primitive subprograms.
11444 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11445 a private extension, only examine visible components before trying to
11446 analyze as a prefixed call.
11447 Change Entity_List to Type_To_Use, for better readability.
11448 (Has_Fixed_Op): Use base type when checking whether the type of an
11449 operator has a user-defined multiplication/division
11450 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
11451 user-defined operators are available for fixed-point types.

11454 Ed Schonberg <schonberg@adacore.com>
11456 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
11457 formal At_Any_Place indicating, when True, that we want to test for
11458 availability of the stream attribute at any place (as opposed to the
11459 current visibility context only).
11460 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11461 purpose of enforcing E.2.2(8) only if it is not available at any place.
11462 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11463 when checking the legality of an extension aggregate in a preelaborable
11464 package. Treat the literal null as a valid default expression in a
11465 component declaration for a type with preelaborable initialization.
11466 A limited interface is a legal progenitor for the designated type of a
11467 remote access to class-wide type.

11475 (Find_Direct_Name): Add comment about Generate_Reference incorrectly
11476 setting the Referenced_As_LHS flag for entities that are implicitly
11478 (Find_Type): If the type is an internally generated incomplete type,
11479 mark the full view as referenced, to prevent spurious warnings.
11480 (Find_Selected_Component, Has_Components): Handle properly non-limited
11481 views that are themselves incomplete types.
11482 Handle interfaces visible through limited-with clauses.
11483 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11484 subprogram generic actual for which we have generated a renaming.
11485 Warn when the renaming introduces a homonym of
11486 the renamed entity, and the renamed entity is directly visible.

11495 the allocator is not a coextension.
11496 (Resolve): Skip an interpretation hidden by an abstract operator only
11497 when the type of the interpretation matches that of the context.
11498 (Resolve): When looping through all possible interpretations of a node,
11499 do not consider those that are hidden by abstract operators.
11500 (Resolve_Actuals): When verifying that an access to class-wide object
11501 is an actual for a controlling formal, ignore anonymous access to
11502 subprograms whose return type is an access to class_wide type.
11503 (Resolve_Slice): If the prefix of the slice is a selected component
11504 whose type depends on discriminants, build its actual subtype before
11505 applying range checks on the bounds of the slice.
11506 (Valid_Conversion): In an instance or inlined body, compare root types,
11507 to prevent anomalies between private and public views.
11508 (Resolve): Improve error message for ambiguous fixed multiplication
11509 expressions that involve universal_fixed multiplying operations.

11529 elabration statements, register the package with the name server
11530 at the beginning, not at the end, of the elaboration statements so
11531 that they can create remote access to subprogram values that designate
11532 remote subprograms from the package.
11534 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
11536 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
11537 values to compute the number of seconds since the Unix Epoc in order to
11538 account for Daylight Savings Time. Perform special processing for dates

12660 an unconstrained array type, and the expression is a slice, use the
12661 bounds of the slice to construct the required constraint checks.
12662 Improve NOT NULL error messages
12663 (Apply_Constraint_Check): If the context is a null-excluding access
12664 type, diagnose properly the literal null.

12680 Arnaud Charlet <charlet@adacore.com>
12682 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12683 applicable to types that have the With_Type flag set. Returns the
12684 non-limited view of the type, if available, otherwise the type itself.
12685 For class-wide types, there is no direct link in the tree, so we have
12686 to retrieve the class-wide type of the non-limited view of the Etype.
12687 New attributes Static_Initialization and Static_Elaboration_Desired.
12688 Remove the pragma Thread_Body, and the associated flag
12689 Is_Thread_Body in entities, and all related code.

12702 (Original_Access_Type): Remove, not needed.
12703 (Root_Type): Handle properly subtypes of class-wide-types.
12706 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12707 class-wide types visible through limited-with clauses.
12708 (Try_Primitive_Operation): When examining all primitive operations of a
12709 tagged type, do not consider subprograms labeled as hidden unless they
12710 belong to a private generic type with a tagged parent.
12711 (Try_Object_Operation): Extensive rewriting, to handle properly various
12712 overloading cases, when several ancestors may have class-wide operations
12713 that are possible candidates, and when the overloaded functions return
12714 array types and have defaulted parameters so that the call may be
12715 interpreted as an indexing.
12716 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12717 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12718 successive actuals before analyzing the call itself.
12719 (Try_Primitive_Operation): A primitive operation is compatible with the
12720 prefix if the prefix has a synchronized type and the type of the formal
12721 is its corresponding record, as can be the case when the primitive
12722 operation is declared outside of the body of the type.
12723 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12724 perform homonym traversal, looking for class-wide operation matches
12725 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12726 access parameters are now restricted to anonymous access types.
12727 (Mark_Allocator): An allocator with a discriminant association parent is
12729 (Try_One_Prefix_Interpretation): If the type of the object is
12730 incomplete, as can be happen when it is a limited view obtained through
12731 a limited_with_clause, the selected component is not part of a prefixed
12733 (Complete_Object_Operation): Diagnose properly an object that is not
12734 aliased when the corresponding controlling formal is an access
12736 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12737 ambiguous calls in prefixed notation, where two primitives differ only
12738 in that the controlling argument of one is an access parameter.
12740 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12741 whether a function that returns an unconstrained type can be inlined.
12742 (Process_Formals): Diagnose properly the illegal use of an incomplete
12743 type in the profile of an access_to_subprogram declaration.
12744 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12745 operations are attached to the corresponding record.
12746 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12747 When processing a primitive of a concurrent type which implements an
12748 interface change the type of all controlling formals to that of the
12749 corresponding record type.
12750 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12751 to determine the tagged type to which a primitive belongs.
12752 (Check_Conventions): Capture condition to ignore a primitive operation
12753 (which is shared between the loop in Check_Conventions and the one in
12754 Check_Convention) in a new local function Skip_Check.
12755 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12756 confusion with Check_Conventions' own Prim_Op local variable.
12757 (Create_Extra_Formals): Test for a tagged result type rather than a
12758 controlling result when determining whether to add a BIP_Alloc_Form
12759 formal and a BIP_Final_List formal to the function.
12760 (Check_Conformance); For parameters that are anonymous access types,
12761 subtype conformance requires that the not null and the constant
12762 indicators must match
12763 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12764 to retrieve the appropriate type when processing a concurrent type
12765 declared within a generic. Minor comment reformatting. Change invocation
12766 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12768 (Analyze_Subprogram_Body): If the return type of a function is an
12769 anonymous access to the limited view of a class-wide type, and the
12770 non-limited view of the type is available, update the type of the
12771 function so that code can be generated.
12772 (Process_Formals): In case of access-subtype itype whose designated
12773 type is also an itype (situation that happens now with access to
12774 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12775 attribute to avoid backend problems.
12776 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12777 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12778 anonymous types' designated types are same before testing
12779 Subtypes_Statically_Match.
12780 (Create_Extra_Formals): Test for a named access parameter that is a
12781 controlling formal as an additional condition for adding an
12782 accessibility level formal. This can occur in the subp type created for
12783 dispatching calls in Expand_Dispatching_Call, and allows calling
12784 Create_Extra_Formals from that procedure rather than special-casing the
12785 extra formals there.
12786 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12787 when the function has a controlling result.
12788 (Check_Returns): Add much more knowledge of the optimization of local
12789 raise statements to gotos, to retain proper warnings in this case.
12790 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12791 nodes when looking for last statement.
12793 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12794 class-wide types visible through limited with clauses.
12795 (Add_One_Interp): If the operands are anonymous access types, the
12796 predefined operator on universal_access is immediately visibles
12797 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12798 other anonymous access types.
12799 (Disambiguate): Take into account CIL convention.
12800 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12802 2007-06-06 Robert Dewar <dewar@adacore.com>

12807 Fix lower bound of tables.
12810 * nlists.adb: Ditto.

12819 * exp_aggr.ads, exp_aggr.adb:
12820 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12821 in extension aggregates.
12822 (Flatten): Other conditions being met, an aggregate is static if the
12823 low bound given by component associations is different from the low
12824 bound of the base index type.
12825 (Packed_Array_Aggregate_Handled): If the component type is itself a
12826 packed array or record, the front-end must expand into assignments.
12827 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12828 Init_Pr, instead of Ancestor_Is_Expression.
12829 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12830 coextension chain root, either generate a list controller or use the
12831 already existing one.
12832 (Static_Array_Aggregate): New procedure to construct a positional
12833 aggregate that can be handled by the backend, when all bounds and
12834 components are compile-time known constants.
12835 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12836 types covering interface types into assignments.
12837 (Replace_Type): move to Build_Record_Aggr_Code.
12838 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12839 interface type, convert to the definite type of the aggregate itself,
12840 so that needed components are visible.
12841 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12842 components and the context is an extended return statement do not
12843 create a transient block for it, to prevent premature finalization
12844 before the return is executed.
12845 (Gen_Assign): Do not generate a call to deep adjust routine if the
12846 component type is itself an array of controlled (sub)-components
12847 initialized with an inner aggregate.
12848 (Component_Check): New name for Static_Check. This name is now more
12849 appropriate, and documentation is added which was missing.
12850 (Component_Check): Add test for bit aligned component value
12851 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12852 Tagged_Comps, name is more appropriate given added function below.
12853 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

12857 Robert Dewar <dewar@adacore.com>
12859 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12860 Terminated: Add unchecked type conversion from System.Address to
12861 System.Tasking.Task_Id when calling the predefined primitive
12863 Disable new Ada 05 accessibility check for JVM.NET targets, which
12864 cannot be implemented in a practical way.
12865 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12866 the sources always references the tag of the actual object. Therefore,
12867 if 'Tag is applied in the sources to class-wide interface objects we
12868 generate code that displaces "this" to reference the base of the object.
12869 (Expand_N_Attribute_Reference, case Size): Return specified size if
12870 known to front end.
12871 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12872 has code that displaces the pointer of the object to manage interface
12873 types. However this code must not be executed when the prefix is a
12874 subprogram. This bug caused the wrong expansion of the internally
12875 generated assignment that fills the dispatch table when the primitive
12876 is a function returning a class-wide interface type.
12877 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12878 Set_Attribute_Name for Name_Unaligned_Valid.

12881 Gary Dismukes <dismukes@adacore.com>
12883 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12884 If the initialization is the equivalent aggregate of the initialization
12885 procedure of the type, do not remove it.
12886 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12887 initialized to null from having their expression reset to empty and
12888 note this exception in the comment.

12909 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12910 constrained subtype for a nominal unconstrained type, use its base type
12911 to check for conformance with the context.
12912 (Resolve_Attribute): Remove test of the access type being associated
12913 with a return statement from condition for performing accessibility
12914 checks on access attributes, since this case is now captured by
12915 Is_Local_Anonymous_Access.
12916 (Analyze_Access_Attribute): Set Address_Taken on entity
12917 (Analyze_Attribute, case Address): Set Address_Taken on entity
12918 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
12919 validating an access attribute whose prefix is a current instance.
12920 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
12921 applied to dispatching operations, if freezing is required then we set
12922 the attribute Has_Delayed_Freeze in the prefix's entity.
12923 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
12924 current scope if access of local subprogram taken
12925 (Analyze_Access_Attribute): Check legality of self-reference even if the
12926 expression comes from source, as when a single component association in
12927 an aggregate has a box association.
12928 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
12929 the prefix if it is a protected operation and the attribute is
12930 Unrestricted_Access.
12931 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
12932 reference to the base type of the context, to force a constraint check
12933 when the context is an access subtype with an explicit constraint.
12934 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
12935 node is rewritten as an interface conversion. leave unanalyzed after
12936 resolution, to ensure that type checking against the context will take

12943 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
12944 wrapper when the full view of the controlling type of an inherited
12945 function that dispatches on result implements interfaces.
12946 (Expand_N_Object_Declaration): In cases where the type of the
12947 declaration is anonymous access, create finalization list for it.
12948 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
12949 if the object has no explicit initialization, to match description of
12950 functionality of pragam Persistent_BSS.

12952 new function to build static aggregates, to replace initialization call
12953 when static initialization is desired.
12954 (Freeze_Type): Generate a list controller for an access type whenever
12955 its designated type has controlled anonymous access discriminants.
12956 (Build_Equivalent_Aggregate): New procedure to compute a static
12957 aggregate to be used as default initialization for composite types,
12958 instead of a generating a call to the initialization procedure for the
12960 (Build_Initialization_Call): When available, replace a call to the
12961 initialization procedure with a copy of the equivalent static aggregate
12963 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
12964 declarations for objects of a class-wide interface type, rather than
12965 just identifiers, to prevent visibility problems.
12966 (Expand_N_Object_Declaration): When expanding the declaration for an
12967 object of a class-wide interface type, preserve the homonym chain of
12968 the original entity before exchanging it with that of the generated
12969 renaming declaration.
12970 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
12971 active, because there is no way to handle the exception.
12972 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
12973 to do a minimum decoration of the Access_Disp_Table list.
12974 (Expand_Record_Controller): Avoid the addition of the controller between
12975 the component containing the tag of a secondary dispatch table and its
12976 adjacent component that stores the offset to the base of the object.
12977 This latter component is only generated when the parent type has
12978 discriminants ---documented in Add_Interface_Tag_Components).
12979 (Apply_Array_Size_Check): Removed, no longer needed.
12980 (Expand_N_Full_Type_Declaration): If the type has anonymous access
12981 components, create a Master_Entity for it only if it contains tasks.
12982 (Build_Init_Procedure): Suppress the tag assignment compiling under
12984 (Freeze_Record_Type): Remove code associated with creation of dispatch
12986 (Init_Secondary_Tags): Update type of actuals when generating calls to
12987 Ada.Tags.Set_Offset_To_Top
12988 (Stream_Operation_OK): Disable use of streams compiling under no
12990 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
12991 if Has_Init_Expression set.
12992 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
12993 Register_Primitive, which provides the same functionality.
12994 (Requires_Init_Proc): Return false in case of interface types.
12995 (Add_Secondary_Tables): Use the new attribute Related_Interface to
12997 (Predefined_Primitive_Freeze): Do not assume that an internal entity
12998 is always associated with a predefined primitive because the internal
12999 entities associated with interface types are not predefined primitives.
13000 Therefore, the call to Is_Internal is replaced by a call to the
13001 function Is_Predefined_Dispatching_Operation.
13002 (Make_Eq_If): When generating the list of comparisons for the
13003 components of a given variant, omit the controller component that is
13004 present if the variant has controlled components.
13006 2007-06-06 Javier Miranda <miranda@adacore.com>
13007 Hristian Kirtchev <kirtchev@adacore.com>
13008 Bob Duff <duff@adacore.com>
13010 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13011 handle the creation of finalization lists and calls for nested
13012 coextensions when the root of the chains is part of a return statement.
13013 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13015 (Expand_Record_Equality): Skip components that are interface types.
13016 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13017 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13018 with Rewrite_Coextension. Change the condition for detecting coextension
13020 (Is_Local_Access_Discriminant): Removed.
13021 (Rewrite_Coextension): New routine which rewrites a static coextension
13022 as a temporary and uses its unrestricted access in the construction of
13024 (Complete_Coextension_Finalization): New routine. Generate finalization
13025 attachment calls to all delayed coextensions.
13026 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13027 the allocator is not a coextension itself and has delayed coextensions.
13028 If the current allocator is controlled, but also a coextension, delay
13029 the generation of the finalization attachment call.
13030 Rename local variable "Node" to "Nod" in order to avoid confusion with
13032 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13033 limited types that are not inherently limited. Such an allocator is
13034 illegal, but is generated by the expander for a return statement, to
13035 copy the result onto the secondary stack. This is the only case where a
13036 limited object can be copied. Generate code to displace the pointer
13037 to the object if the qualified expression is a class-wide interface
13038 object. Such displacement was missing and hence the copy of the object
13040 (Apply_Accessibility_Check): Handle allocated objects initialized in
13042 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13043 and Expand_Allocator_Expression. Allocating class-wide interface objects
13044 this routine displaces the pointer to the allocated object to reference
13045 the component referencing the corresponding secondary dispatch table.
13046 Expand_Allocator_Expression): Add missing support to allocate class-wide
13047 interface objects initialized with a qualified expression.
13048 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13049 function result type, and use the finalization list associated with the
13050 function scope in that case (such an anonymous type should not be
13051 treated like an access parameter's type).
13053 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13054 Gary Dismukes <dismukes@adacore.com>
13055 Javier Miranda <miranda@adacore.com>
13057 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13058 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13059 required exception handler.
13060 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13061 properly the case of a function whose return type is a limited
13062 class-wide interface type. Modify the code of the accessibility
13063 check to handle class-wide interface objects. In this case we need to
13064 displace "this" to reference the primary dispatch table to get access
13065 to the TSD of the object (to evaluate its accessibility level).
13066 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13067 rather than a controlling result as one of the conditions for
13068 generating tests of the implicit BIP_Alloc_Form formal. The
13069 initialization assignment is also handled according to whether the
13070 result is tagged instead of controlling.
13071 In the case where the init assignment is inserted in the "then" part of
13072 the allocation conditional, rewrite the target to be a dereference of
13073 the implicit BIP_Object_Access formal.
13074 If the returned value is unconstrained and created on the secondary
13075 stack, mark the enclosing block and function so that the secondary
13076 stack is not reclaimed on return.
13077 Treat returns from functions with controlling results similarly to
13078 returns from functions with unconstrained result subtypes.
13079 If the object returned is unconstrained, and an allocator must be
13080 created for it, analyze the allocator once the block for the extended
13081 return is installed, to ensure that finalizable components
13082 of the expression use the proper finalization list. Guard the call to
13083 Move_Final_List with a check that there is something to finalize.
13084 (Make_Tag_Ctrl_Assignment): Use "old" handling
13085 of controlled type assignment for virtual machines, since new code uses
13086 unsupported features (such as direct access to bytes in memory).
13088 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13089 Ed Schonberg <schonberg@adacore.com>
13091 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13092 accessibility actual, check for the case of an aliased object that has
13093 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13094 we fall into processing for the attribute rather than the name of the
13096 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13097 formal has its address taken in the body, create a temporary to capture
13098 value. If the return type is a limited interface, do not treat the
13099 return value as Controlled.
13100 (Is_In_Place_Function): If the return type is a limited interface,
13101 treat as returning in place. The actual returned object may not always
13102 be limited, but the caller has to assume that it is returned in place.
13103 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13104 context of an allocator, use the correct finalization chain (that is,
13105 the chain belonging to the access type, rather than the chain belonging
13106 to the current scope).
13107 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13108 result type rather than a controlling result as a precondition for
13109 adding an allocation form actual to a build-in-place call.
13110 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13111 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13112 primitive in the dispatch tables. This work is now done by Make_DT when
13113 the type is frozen.
13114 (Register_Predefined_DT_Entry): Removed.
13115 (Add_Return): If end label is not present, use sloc of last statement
13116 for generated return statement in procedure, for better gdb behavior
13118 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13119 object address nodes to ensure proper processing by routines like
13121 (Expand_Call): Fix generation of validity check for parameter
13122 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13123 the allocation form parameter if the result subtype is constrained,
13124 except when the function has a controlling result.
13125 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13126 rather than Is_Controlled and Has_Controlled_Component, since we want to
13127 include class-wide result types in this treatment. Also test for a
13128 controlling result, since that also requires passing a finalization
13130 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13131 even when the result subtype is constrained, to handle calls involving
13132 controlling results.
13133 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13134 is now called even when the result subtype is constrained, to handle
13135 calls involving controlling results.
13136 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13137 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13138 now performs the test).
13139 (Make_Build_In_Place_Call_In_Object_Declaration):
13140 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13141 constrained, to handle calls involving controlling results.
13142 (Add_Return): Accomodate rewritten pattern from local raise to goto
13143 transformation, so that we still recognize an transfer statement
13144 and do the right thing here in that case.
13145 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13146 and end of subprogram code.
13147 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13148 support for primitives that are functions (without formals) with a
13149 controlling result.
13150 (Inherited_From_Formal): If the actual subtype has not generic parent
13151 type, it is not an actual for a formal derived type, and there is no
13152 operation to inherit from the formal.
13154 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13155 Thomas Quinot <quinot@adacore.com>
13157 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13158 inserted cleanup code appropriately for GDB use.
13159 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13160 exception handler for Deep_Adjust or Deep_Finalize.
13161 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13162 Raise_From_Controlled_Operation is available, use a call to that
13163 subprogram instead of a plain "raise Program_Error" node to raise
13164 Program_Error if an exception is propagated from an Adjust or Finalize
13166 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13167 appears in the optional statement list of a triggering alternative, the
13168 scope actions can be inserted directly there, and not in the list that
13169 includes the asynchronous select itself.
13171 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13172 Robert Dewar <dewar@adacore.com>
13173 Hristian Kirtchev <kirtchev@adacore.com>
13175 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13176 generated exception handler appropriately when debugging generated code.
13177 Deal properly with No_Exception_Propagation restriction mode.
13178 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13179 System.Address to System.Tasking.Task_Id when processing the result of
13180 the predefined primitive _disp_get_task_id.
13181 (Expand_N_Asynchronous_Select): Clarify comment.
13182 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13183 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13184 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13185 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13186 privals and for generated call to Complete_Entry_Body, for better gdb
13188 (Copy_Result_Type): Utility to construct a parameter and result profile
13189 for protected functions whose return type is an anonymous access to
13191 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13193 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13194 point when the local-raise-to-goto transformation has taken place.
13196 2007-06-06 Javier Miranda <miranda@adacore.com>
13197 Nicolas Setton <setton@adacore.com>
13199 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13200 functionality when the backend is generating code.
13201 Otherwise any serious error
13202 reported by the backend calling the frontend routine Error_Msg
13203 changes the Compilation_Mode to Check_Semantics, disables the
13204 functionality of this routine and causes the generation of
13205 spureous additional errors.
13207 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13208 debugging information now generated by the compiler for fat-pointer
13210 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13212 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13214 2007-06-06 Thomas Quinot <quinot@adacore.com>
13216 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13217 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13218 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13219 For a remote call to a function with a classwide return type, apply an
13220 E.4(18) check to the returned value.
13221 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13222 stream attributes of the designated type of an RACW, as they are not
13223 dispatching primitive operations.
13225 2007-06-06 Geert Bosch <bosch@adacore.com>
13227 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13229 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13231 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13232 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13234 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13236 2007-06-06 Javier Miranda <miranda@adacore.com>
13238 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13239 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13241 2007-06-06 Javier Miranda <miranda@adacore.com>
13243 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13244 deallocation of class-wide interface objects.
13245 (Expand_Dispatching_Constructor_Call): Take into account that if the
13246 result of the dispatching constructor is an interface type, the
13247 function returns a class-wide interface type; otherwise the returned
13248 object would be actual. The frontend previously accepted returning
13249 interface types because Expand_Interface_Actuals silently performed
13250 the management of the returned type "as if" it were a class-wide
13252 (Expand_Dispatching_Constructor_Call): Replace call to
13253 Make_DT_Access_Action by direct call to Make_Function_Call.
13255 2007-06-06 Robert Dewar <dewar@adacore.com>
13256 Ed Schonberg <schonberg@adacore.com>
13258 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13259 compute masking constant, since we now set Esize properly to the
13261 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13262 to match the alignment.
13263 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13264 packed arrays of 8 bits or less.
13266 * freeze.adb (Freeze_Entity): When freezing the formals of a
13267 subprogram, freeze the designated type of a parameter of an access type
13268 only if it is an access parameter.
13269 Increase size of C convention enumeration object
13270 (Freeze_Entity, array type case): Make sure Esize value is properly
13271 adjusted for the alignment if it is known.
13272 (Freeze_Entity, array type case): When checking bit packed arrays for
13273 the size being incorrect, check RM_Size, not Esize.
13274 (Freeze_Record_Type): Check for bad discriminated record convention
13275 (In_Exp_Body): Return true if the body is generated for a subprogram
13276 renaming, either an attribute renaming or a renaming as body.
13277 (Check_Itype): If the designated type of an anonymous access component
13278 is a non-protected subprogram type, indicate that it is frozen, to
13279 prevent out-of-scope freeze node at some subsequent call.
13280 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13281 only if the subprogram is neither imported nor exported, as well as the
13282 NCA descriptor class if the subprogram is exported.

13287 Gary Dismukes <dismukes@adacore.com>
13289 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13290 default initialization on an imported object, when there is no
13291 initialization call generated for it.
13292 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13295 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13296 Static_Elaboration_Desired.
13297 Remove pragma Thread_Body.
13298 Implement a new pragma No_Body
13299 Removes the Explicit_Overriding pragma
13300 Remove Optional_Overriding pragma
13301 (Prag): Deal with Universal_Aliasing.
13302 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13303 Pragma_CIL_Constructor): New names.
13305 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13306 uses the equivalent aggregate of a type must be treated as an implicit
13308 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13309 has none of the other categories.
13310 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13311 to apply Import to an object renaming declaration.
13313 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13314 from a C++ class should be declared as limited and that it will be
13315 considererd limited.
13316 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13317 should be declared as limited and that it will be considererd limited.
13318 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13319 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
13320 (Analyze_Pragma): Deal with Universal_Aliasing.
13321 (Sig_Flags): Likewise.
13322 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
13323 (Overflow_Checks_Unsuppressed): New flag.
13324 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
13325 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
13326 case of JVM or .NET targets, and compiling user code.
13327 Add debugging convenience routine rv
13329 2007-06-06 Robert Dewar <dewar@adacore.com>
13331 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
13332 are interface type.
13333 (Build_Elementary_Input_Call): For floating-point use right type in the
13334 absence of strange size or stream size clauses.
13335 (Build_Elementary_Write_Call): Same fix
13336 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
13337 set to value that does not match base type size.
13339 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13341 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13342 object of a limited type can be initialized with a call to a function
13343 that returns in place. If the limited type has unknown discriminants,
13344 and the underlying type is a constrained composite type, build an actual
13345 subtype from the function call, as is done for private types.
13346 (Side_Effect_Free): An expression that is the renaming of an object or
13347 whose prefix is the renaming of a object, is not side-effect free
13348 because it may be assigned through the renaming and its value must be
13349 captured in a temporary.
13350 (Has_Controlled_Coextensions): New routine.
13351 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13352 as is done for other limited types.
13353 (Non_Limited_Designated_Type): new predicate.
13354 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
13356 Remove all handling of with_type clauses.
13358 * par-ch10.adb: Remove all handling of with_type clauses.
13360 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
13361 checksum if the main source could not be parsed.
13362 (Loat_Unit): When processing a child unit, determine properly whether
13363 the parent unit is a renaming when the parent is itself a child unit.
13364 Remove handling of with_type clauses.
13366 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.
13367 (Set_Is_Static_Coextension): New procedure.

13371 (Has_Init_Expression): New flag
13372 (Delay_Finalize_Attach): Remove because flag is obsolete.
13373 (Set_Delay_Finalize_Attach): Remove because flag is obsolete.

13377 2007-06-06 Vincent Celier <celier@adacore.com>
13378 Robert Dewar <dewar@adacore.com>
13380 * frontend.adb (Frontend): Return immediately if the main source could
13381 not be parsed, because of preprocessing errors.
13383 * gnat1drv.adb (gnat1drv): Handle RE_Not_Available gracefully.
13384 (Gnat1drv): Exit with errors if the main source could not be parsed,
13385 because of preprocessing errors.
13386 (Check_Rep_Info): New procedure
13388 2007-06-06 Robert Dewar <dewar@adacore.com>
13390 * g-hesorg.ads, g-heasor.ads,

15210 to handle properly the anonymous access case.
15212 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
15213 for all access attributes, because overload resolution should work the
15214 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
15215 causes the error message for the ambiguous "X'Access = Y'Access" and
15216 "X'Unrestricted_Access = Y'Access" and so forth to match.
15217 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
15218 now that anonymous access to protected operations have their own kind.

15224 attempt to derive from a synchronized tagged type.
15225 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
15226 type, inherit the class-wide type already created, because it may
15227 already have been used in a self-referential anonymous access component.
15228 (Mentions_T): Recognize self-referential anonymous access components
15229 that use (a subtype of) the class-wide type of the enclosing type.
15230 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15231 Derived_Type for Prev formal on call to
15232 Check_Anonymous_Access_Components rather than Empty.
15233 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15234 a record extension in deciding whether to create a class-wide type,
15235 rather than just checking Tagged_Present.

15237 to stand-alone object declarations as well as component declarations.
15238 (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to
15239 prevent accidental overwriting when enclosing package appears in
15240 a limited_with_clause.
15241 (Array_Type_Declaration): If the component type is an anonymous access,
15242 the associated_node for the itype is the type declaration itself.

15248 to complete the decoration of synchronized interface types. Add also
15249 a call to Check_Abstract_Interfaces to verify the ARM rules.

15251 with abstract interfaces.
15252 (Analyze_Subtype_Indication): Resolve the range with the given subtype
15253 mark, rather than delaying the full resolution depending on context.

15279 Do not collect arguments if project is externally built.
15280 (Compile_Sources): Do nothing, not even check if the source is up to
15281 date, if its project is externally built.
15282 (Compile): When compiling a predefined source, add -gnatpg
15283 as the second switch, after -c.
15284 (Compile_Sources): Allow compilation of Annex J renames without -a
15285 (Is_In_Object_Directory): Check if the ALI file is in the object
15286 even if there is no project extension.
15287 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
15288 gnatbind if the ALI file effectively exists.
15289 (Initialize): Add the directory where gnatmake is invoked in front of
15290 the path if it is invoked from a bin directory, even without directory
15291 information, so that the correct GNAT tools will be used when spawned

15312 Unchecked_Deallocation only when Renamings_Included is True.
15314 * par.adb: Allow library units Calendar, Machine_Code,
15315 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15316 when -gnatg is not specified.
15317 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15318 there is no need to generate always a record_definition_node in case
15319 of synchronized interface types.
15320 (SIS_Entry_Active): Initialize global variable to False
15321 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

15346 (Convert_Aggr_In_Allocator): If the allocator is for an access
15347 discriminant and the type is controlled. do not place on a finalization
15348 list at this point. The proper list will be determined from the
15350 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
15351 initialize record controller if needed, before the components, to ensure
15352 that they are properly finalized.

15365 accessibility on class-wide allocators if the allocator occurs at the
15366 same scope level as the allocator's type. The check is guaranteed to
15367 succeed in that case, even when the expression originates from a
15368 parameter of the containing subprogram.
15369 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15370 under No_Dispatching_Calls restriction. During the semantic analysis
15371 we already notified such violation.
15372 (Tagged_Membership): Constant folding. There is no need to check
15373 the tag at run-time if the type of the right operand is non
15374 class-wide abstract.
15375 Replace call to Is_Ancestor by call to Is_Parent
15376 to support concurrent types with interface types.
15377 (Expand_N_Allocator): Add an assertion associated with the generation

15388 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
15389 initialize most the TSD components by means of an aggregate.
15390 Modify the declaration of the object containing the TSD
15391 because we now expand code that has a higher level of abstraction.
15392 The TSD has a discriminant containing the Inheritance Depth Level,
15393 value that is used in the membership test but also to fix the size
15394 of the table of ancestors.
15395 (Expand_Interface_Conversion): Insert function body at the closest place
15396 to the conversion expression, to prevent access-before-elaboration
15397 errors in the backend.

15399 compiling under restriction No_Dispatching_Calls plus code cleanup.
15400 Code reorganization plus removal of calls to Set_Num_Prim_Ops

15423 (Expand_Dispatching_Call): Replace generation of call to the run-time
15424 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15425 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15427 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15428 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
15429 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
15430 Build_Set_Prim_Op_Address.

15432 (Init_Predefined_Interface_Primitives): Replace generation of call to
15433 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
15436 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15437 First (Parameter_Associations ()) with the call to First_Actual that
15438 returns an actual parameter expression for both named and positional
15441 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15442 check violation of restriction No_Dispatching_Calls.
15443 (Check_Controlling_Type): A formal of a tagged incomplete type is a
15444 controlling argument.

15447 First/Next_Component_Or_Discriminant
15448 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
15449 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15450 specify Any_Limited_Interface, and this functionality is already
15451 provided by the function Has_Abstract_Interfaces.
15452 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15453 support concurrent types implementing interfaces.
15454 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15455 specify kind Any_Limited_Interface, and this functionality is already
15456 provided by the function Has_Abstract_Interfaces.
15457 (Remove_Side_Effects): replace Controlled_Type by
15458 CW_Or_Controlled_Type whenever the issue is related to
15459 using or not the secondary stack.
15461 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
15462 P_Interface_Type_Definition to fulfill the new interface (the formal
15463 Is_Synchronized is no longer required).

15475 anonymous, use finalization list of enclosing dynamic scope.
15476 (Expand_N_Package_Declaration): For a library package declaration
15477 without a corresponding body, generate RACW subprogram bodies in the
15478 spec (just as we do for the task activation call).
15479 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15480 Is_Abstract_Type. Make sure these are called only when appropriate.
15481 Remove all code for DSP option

15498 Family_Size with 'Cap' set to true.
15499 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15500 a protected version of an operation declared in the private part of
15501 a protected object, because they may be invoked through a callback.
15502 (Set_Privals): If the type of a private component is an anonymous access
15503 type, do not create a new itype for each protected body.
15504 If the body of a protected operation creates
15505 controlled types (including allocators for class-widetypes), the
15506 body of the corresponding protected subprogram must include a

15513 for a possible overriding candidate.
15514 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15515 hold an actual parameter value since its initialization is separated

15520 Pablo Oliveira <oliveira@adacore.com>
15522 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):

15525 Build_From_Any_Call.
15526 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15527 E_Constant, depending upon Variable formal.
15528 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15529 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15530 parameter that requires an extra constrained parameter, declare
15531 temporary for actual as a variable, not a constant.
15532 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15533 the unit being compiled is the one that contains the stub type.
15534 Change primitive operation name for the RACW associated with a RAS
15535 from Call to _Call so it cannot clash with any legal identifier.
15536 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15538 (Append_RACW_Bodies): New subprogram.
15539 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15540 Add_Receiving_Stubs_To_Declarations functions.
15541 When expanding a package body, this list correspond to the

15546 registering the receiving stubs at the end of the 'Stmts' list.
15547 (RCI_Package_Locator): Pass the new Version generic formal when
15548 instantiating a RCI_Locator package.
15549 (Build_From_Any_Function): To compute the High bound for an
15550 unconstrained array actual, we add the Low bound with the length.
15551 Thus we must convert the low bound and the length to an appropriate
15552 type before doing the sum.
15553 (Build_Subprogram_Receiving_Stubs, PolyORB):
15554 * Retrieve the extra formals parameters at the
15555 end of the parameter stream.
15556 * Use Move_Any_Value to write back out parameters
15557 after executing the request as it is more efficient
15558 than Copy_Any_Value.
15559 * Build the any containing Extra Formals with the
15560 appropriate typecode.
15561 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15562 empty Component_List.
15563 (Build_Actual_Object_Declaration): New subprogram. Build and insert into

15575 function with the first not implicit parent type.
15576 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15577 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15578 typecode from the Etype. Therefore we retrieve the correct typecode
15579 with a call to Get_Any_Type.
15580 (Copy_Specification): Do controlling formal type substitution based on
15581 Is_Controlling_Formal flag, instead of caller-provided object type.
15582 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15583 a RACW primitive operation, we might get a subprogram declaration for an
15584 ancestor of the RACW designated type (not for the designated type
15585 itself), in the case where this operation is inherited. In this case we
15586 have no easy means of determining the original tagged type for which
15587 the primitive was declared, so instead we now rely on
15588 Copy_Specification to use the Is_Controlling_Formal flag to determine
15589 which formals require type substitution.

15597 handler unsuitable as a target for a local raise statement.
15598 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15599 run-time subprogram CW_Membership by call to Build_CW_Membership.
15600 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15601 by a function call, a temporary must be created before expanding the
15602 Constructor_Call itself, to prevent out-of-order elaboration in the
15603 back-end when stack checking is enabled..

15734 This is needed as it is necessary to have access to both versions in the
15735 runtime for the form parameter encoding support.
15736 This set of patch add support for the encoding form parameter.
15737 (S2WS): Improve implementation to handle cases where the filename is not
15738 UTF-8 encoded. In this case we default to using the current code page
15739 for the conversion.
15741 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration

15786 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
15787 __gnat_adjust_context_for_raise.
15788 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
15789 implementation of floating point operations as native x86 targets.
15790 So the FPU should be initialized in the same way using finit. Fix
15791 floating point operations accuracy issues.
15792 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
15793 member in struct sigaction, so as to avoid warning for incompatible

15812 Modify the loop that collects type references, to include interface
15813 types that the type implements. List each of these interfaces when
15814 building the entry for the type.
15815 (Generate_Definition): Initialize component Def and Typ of new entry
15816 in table Xrefs, to avoid to have these components unitialized.

15874 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
15875 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15876 there is no need to generate always a record_definition_node in case
15877 of synchronized interface types.
15878 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
15879 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
15880 illegal in Ada 95, in cases where it is legal. Change the warnings to
15881 errors in other cases. Don't give the error unless the "not null"
15882 parses properly. Correct the source position at which the error occurs.
15883 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to

15962 If the prefix returned by Sdefault is null, get the prefix from a call
15963 to Executable_Prefix_Path.
15964 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is

16020 Expand_Limited_With_Clause): Use a new copy of selector name in the
16021 call to Make_With_Clause. This fixes the tree structure for ASIS
16022 purposes. Nothing is changed in the compiler behaviour.
16023 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16024 a package renaming.
16025 (Install_Limited_With_Clauses): Do not install non-limited view when it
16026 is still incomplete.
16028 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16029 Gary Dismukes <dismukes@adacore.com>
16031 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16032 when capturing size information, instead of base type, which for a
16033 formal array type will be the unconstrained type.
16034 (Analyze_Formal_Object_Declaration): Add check for illegal default
16035 expressions for a formal in object of a limited type.
16036 (Instantiate_Object): Ditto.
16037 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16038 because they were defaulted in the formal package and no check applies
16040 (Check_Formal_Package_Instance): Extend conformance check to other
16041 discrete types beyond Integer.
16042 (Process_Default): Copy directly the unmatched formal. A generic copy
16043 has already been performed in Analyze_Formal_Package.
16044 (Analyze_Associations): If a formal subprogram has no match, check for
16045 partial parametrization before looking for a default, to prevent
16047 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16048 not set the instantiation environment before analyzing the actuals.
16049 Fixes regression on 8515-003 with implementation of AI-133.
16050 Set_Instance_Env checks whether the generic unit is a predefined
16051 unit, in which case the instance must be analyzed with the latest Ada
16052 mode. This setting must take place after analysis of the actuals,
16053 because the actuals must be analyzed and frozen in the Ada mode extant
16054 outside of the current instantiation.
16055 (Save_Env, Restore_Env): Preserve and restore the configuration
16056 parameters so that predefined units can be compiled in the proper Ada

16067 Gary Dismukes <dismukes@adacore.com>
16069 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16070 prefix type is a discriminated subtype of the type of the formal.
16071 (Analyze_Allocator): Collect all coextensions regardless of the context.
16072 Whether they can be allocated statically is determined in exp_ch4.
16073 (Analyze_Selected_Component): If the prefix is a limited view and the
16074 non-limited view is available, use the non-limited one.
16075 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16076 therefore illegal), suggest a qualified expression rather than a type
16077 conversion, because a type conversion would be illegal in this context.
16078 (Anayze_Allocator): Trace recursively all nested allocators so that all
16079 coextensions are on the corresponding list for the root. Do no mark
16080 coextensions if the root allocator is within a declaration for a stack-
16081 allocated object, because the access discriminants will be allocated on
16083 (Analyze_Call): Remove restriction on calls to limited functions for the
16084 cases of generic actuals for formal objects, defaults for formal objects
16085 and defaults for record components.
16086 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16087 element list. Their expansion is delayed until the enclosing allocator
16088 is processed and its finalization list constructed.
16089 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16090 for an operation with the given name among the primitive operations of
16091 the corresponding record type.
16092 (Analyze_Selected_Component): If the prefix is a task type that
16093 implements an interface, and there is no entry with the given name,
16094 check whether there is another primitive operation (e.g. a function)
16096 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16097 properly the indexing of a function call written in prefix form, where
16098 the function returns an array type, and all parameters of the function
16099 except the first have defaults.
16100 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16101 the original operands, rather than relocating them, for efficiency and
16102 to work properly when an operand is overloaded.
16103 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16104 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16105 (Analyze_Selected_Component): If the prefix is a private extension, only
16106 scan the visible components, not those of the full view.
16107 (Try_Primitive_Operation): If the operation is a procedure, collect all
16108 possible interpretations, as for a function, because in the presence of
16109 classwide parameters several primitive operations of the type can match

16139 identifier, and be special-cased in Check_Completion.
16140 Mark the full view of the designated type for the RACW associated with
16141 a RAS as Comes_From_Source to get proper view switching when installing
16142 private declarations.
16143 Provite a placeholder nested package body along with the nested spec
16144 to have a place for Append_RACW_Bodies to generate the calling stubs
16145 and stream attributes.

16174 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16175 dereference of a local object R created as a reference to another
16176 object O, use the access level of O.
16177 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16178 rather than local Same_Formal_Type, to check whether protected operation
16179 overrides an inherited one.
16180 (Same_Formal_Type): New predicate, used when matching signatures of
16181 overriding synchronized operations, to handle the case when a formal
16182 has a type that is a generic actual.
16183 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16184 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.

16198 of E2. For a concurrent type its parent is the first element of its
16199 list of interface types; for other types this function provides the
16200 same result than Is_Ancestor.
16201 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16202 (Collect_Synchronized_Interfaces): Removed because the subprogram
16203 Collect_Abstract_Interfaces provides this functionality.
16204 (Collect_Abstract_Interfaces): Minor update to give support to
16205 concurrent types and thus avoid undesired code duplication.
16206 (Get_Subprogram_Entity): Handle entry calls.

16249 high bound is constant and the slice is empty. Tidy.
16250 (tree_transform, case N_Op_Not): Handle properly the case where the
16251 operation applies to a private type whose full view is a modular type.
16252 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16253 Address_Clause, use the associated Expression as the GNAT tree
16254 representing the choice value to ensure the corresponding GCC tree is
16255 of the proper kind.
16256 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16257 instead of just the operands, as the base GCC stabilize_reference does.
16258 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16259 requested; otherwise fail.
16260 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16520 (mainly static expression evaluation).
16521 Reword some continuation messages
16522 Add some \\ sequences to continuation messages
16523 (Resolve_Call): Refine infinite recursion case. The test has been

16539 Valid_Conversion, to incorporate accessibility checks for arrays of
16540 anonymous access types.
16541 (Valid_Conversion): For a conversion to a numeric type occurring in an
16542 instance or inlined body, no need to check that the operand type is
16543 numeric, since this has been checked during analysis of the template.

17009 (__gnat_set_globals): Now a dummy function.
17010 (__gnat_handle_vms_condition): Feed adjust_context_for_raise with
17011 mechargs instead of sigargs, as the latter can be retrieved from the

17059 (Set_All_DT_Position): Hidden entities associated with abstract
17060 interface primitives are not taken into account in the check for

17072 alias of a predefined dispatching primitive.
17073 (Make_DT): If the ancestor of the type is a CPP_Class and we are
17074 compiling under full ABI compatibility mode we avoid the generation of
17075 calls to run-time services that fill the dispatch tables because under
17076 this mode we currently inherit the dispatch tables in the IP subprogram.
17077 (Write_DT): Emit an "is null" indication for a null procedure primitive.
17078 (Expand_Interface_Conversion): Use an address as the type of the formal
17079 of the internally built function that handles the case in which the

17130 we request a discriminal value only in case of discriminants.
17131 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17132 assignments where the target subtype is unconstrained and the target
17133 object is a parameter or dereference (other aliased cases are known

17250 are build-in-place function calls.
17251 (Replace_Self_Reference): New subsidiary of
17252 Make_OK_Assignment_Statement, to replace an access attribute that is a
17253 self-reference into an access to the appropriate component of the
17254 target object. Generalizes previous mechanism to handle self-references
17255 nested at any level.
17256 (Is_Self_Referential_Init): Remove, not needed.

17263 default initialization.
17264 (Make_OK_Assignment_Statement): If the expression is of the form
17265 Typ'Acc, where Acc is an access attribute, the expression comes from a
17266 default initialized self-referential component.
17267 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17268 that has been derived from several abstract interfaces we must also

17277 (Expand_Access_To_Protected_Op): If the context indicates that an access
17278 to a local operation may be transfered outside of the object, create an
17279 access to the wrapper operation that must be used in an external call.

17297 subcomponent's enclosing variable is aliased with a constrained subtype.
17298 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17299 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17300 an aliased prefix must be known to be constrained in order to use True
17301 for the attribute value, and now it's possible for some aliased views
17302 to be unconstrained.

17317 otherwise we incorrectly register the tag of the interface in the final
17319 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17320 generate the wrapper if the parent primitive is abstract. This is
17321 required to report the correct error message.
17322 (Expand_N_Subtype_Indication): Do validity checks on range
17323 (Clean_Task_Names): If an initialization procedure includes a call to

17332 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17333 Object_Declaration to the call.
17334 (Freeze_Type): When the designated type of an RACW was not frozen at the
17335 point where the RACW was declared, validate the primitive operations
17336 with respect to E.2.2(14) when it finally is frozen.
17337 (Build_Initialization_Call,Expand_Record_Controller): Rename
17338 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17339 return-by-reference has no meaning in Ada 2005.

17341 to register tag of the immediate ancestor interfaces in the
17342 run-time structure.

17344 initialization of extension aggregates with abstract interfaces.
17345 (Build_Master_Renaming): Make public, for use by function declarations
17346 whose return type is an anonymous access type.
17347 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17348 Insert_List_Before_And_Analyze after the generation of the specs
17349 associated with null procedures.
17350 (Expand_Tagged_Root): Update documentation in its specification.
17351 (Init_Secondary_Tags): Update documentation.
17352 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17353 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17354 then generate code to inherit the contents of the dispatch table
17355 directly from the ancestor.
17356 (Expand_Record_Controller): Insert controller component after tags of
17357 implemented interfaces.
17358 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to

17362 declarations for overriding null primitives inherited from interfaces.
17363 (Is_Null_Interface_Procedure): New function in
17364 Make_Null_Procedure_Specs.
17365 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17366 immediate ancestor of a tagged type is an abstract interface type we
17367 must generate the specification of the predefined primitives associated
17368 with controlled types (because the dispatch table of the ancestor is
17369 null and hence these entries cannot be inherited). This is required to
17370 elaborate well the dispatch table.

17384 the maximum for type T.
17385 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17386 when the allocator is initialized by a build-in-place call, since the
17387 allocator is already rewritten as a reference to the function result,
17388 and this prevents an unwanted duplication of the function call.
17389 Add with and use of Exp_Ch6.
17390 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17391 is a call to build-in-place function and apply
17392 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17393 untagged designated types).
17394 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17395 optimization if source or target is biased.
17396 (Expand_N_Allocator): Add comments for case of an allocator within a

17414 in order to alleviate the upward compatibility introduced by AI-318.

17425 (Expand_N_If_Statement): Handle new -gnatwt warning
17426 (Expand_N_Case_Statement): Handle new -gnatwt warning
17427 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17428 a protected object.
17429 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17430 validity checking of assignments to elementary record components.
17431 (Expand_N_Return_Statement): return Class Wide types on the secondary
17432 stack independantly of their controlled status since with HIE runtimes,
17433 class wide types are not potentially controlled anymore.
17435 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17438 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17439 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17440 it expects a block, procedure, or task. The return statement will get
17441 turned into a block, and Expand_Cleanup_Actions will happen then.

17444 Ed Schonberg <schonberg@adacore.com>
17445 Bob Duff <duff@adacore.com>
17446 Gary Dismukes <dismukes@adacore.com>
17448 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17450 (Expand_Inlined_Call): Tagged types are by-reference types, and
17451 therefore should be replaced by a renaming declaration in the expanded
17452 body, as is done for limited types.
17453 (Expand_Call): If this is a call to a function with dispatching access
17454 result, propagate tag from context.
17455 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17457 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17458 build-in-place when the right-hand side of an assignment is a
17459 build-in-place function call.
17460 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17461 of the explicit dereference of the allocator to the result subtype of
17462 the build-in-place function. This is needed to satisfy type checking
17463 in cases where the caller's return object is created by an allocator for
17464 a class-wide access type and the type named in the allocator is a
17466 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17467 conversion of the reference to the declared object to the result subtype
17468 of the build-in-place function. This is needed to satisfy type checking
17469 in cases where the declared object has a class-wide type. Also, in the
17470 class-wide case, change the type of the object entity to the specific
17471 result subtype of the function, to avoid passing a class-wide object
17472 without explicit initialization to the back end.
17473 (Register_Interface_DT_Entry): Moved outside the body of
17474 Freeze_Subprogram because this routine is now public; it is called from
17475 Check_Dispatching_Overriding to handle late overriding of abstract
17476 interface primitives.
17477 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17478 adding an implicit access actual on a call to a build-in-place function.
17479 (Expand_Actuals): Test for an actual parameter that is a call to a
17480 build-in-place function and apply
17481 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17482 (Is_Build_In_Place_Function): New function to determine whether an
17483 entity is a function whose calls should be handled as build-in-place.
17484 (Is_Build_In_Place_Function_Call): New function to determine whether an
17485 expression is a function call that should handled as build-in-place.
17486 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17487 calls to build-in-place functions as the initialization of an allocator.
17488 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17489 handling calls to build-in-place functions in contexts that do not
17490 involve init of a separate object (for example, actuals of subprogram
17492 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17493 handling calls to build-in-place functions as the initialization of an
17494 object declaration.
17495 (Detect_Infinite_Recursion): Add explicit parameter Process to
17496 instantiation of Traverse_Body to avoid unreferenced warning.
17497 (Check_Overriding_Inherited_Interfaces): Removed.
17498 (Register_Interface_DT_Entry): Code cleanup.
17499 (Register_Predefined_DT_Entry): Code cleanup.
17500 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17501 inlined statements if within a transient scope.
17502 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17503 formal parameters with occurrences of actuals in inlined body, establish
17504 visibility on the proper view of the actual's subtype for the body's
17506 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17507 compatibility mode and we have an imported CPP subprogram because
17508 for now we assume that imported CPP primitives correspond with
17509 objects whose constructor is in the CPP side (and therefore we
17510 don't need to generate code to register them in the dispatch table).
17511 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17512 aligned selected component.
17513 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17514 the actual of an in-mode parameter is a type conversion.
17515 (Expand_Actuals): If the call does not come from source and the actual
17516 is potentially misaligned, let gigi handle it rather than rejecting the
17517 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17518 Class Wide types as returning by reference independantly of their
17519 controlled status since with HIE runtimes class wide types are not
17520 potentially controlled anymore.
17522 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17524 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17525 references that are private components of the protected object.
17526 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
17527 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17528 instantiation to deal with warnings.
17529 (Initialize_Protection): If expression for priority is non-static, use
17530 System_Priority as its expected type, in case the expression has not
17533 2006-10-31 Robert Dewar <dewar@adacore.com>
17535 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17536 initialization of Homonym_Len.
17537 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17538 names from fully qualified name. Fixes problem of duplicate
17539 external names differing only in the presence of such a block name.
17541 2006-10-31 Thomas Quinot <quinot@adacore.com>
17542 Pablo Oliveira <oliveira@adacore.com>
17544 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17545 subprogram Ids, even if they are not yet assigned.
17546 (Build_Subprogram_Id): It is now this function that will take care of
17547 calling Assign_Subprogram_Ids if necessary.
17548 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17549 should be done only once they are assigned.
17550 (Build_From_Any_Function, case of tagged types): Add missing call to
17552 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17553 type for an RACW type.
17554 (Add_RACW_Features): When processing an RACW declaration for which the
17555 designated type is already frozen, enforce E.2.2(14) rules immediately.
17556 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17557 special reordering of controlling formals.
17559 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17560 associated stub type for an RACW type.
17562 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17564 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17565 fixed-point operations in an integer context, i.e. as operands of a
17566 conversion to an integer type, indicate that result must be rounded.
17568 2006-10-31 Robert Dewar <dewar@adacore.com>
17570 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17571 cases, pass the encoding method, since it is now required by the run
17574 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17575 assumption that Str'First = 1.
17576 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17577 it on to the Value_Wide_Wide_Character call.
17578 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17579 properly handles a string of the form quote-encoded_wide_char-quote.
17581 * s-wchcnv.adb: Minor reformatting
17583 2006-10-31 Javier Miranda <miranda@adacore.com>
17585 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17586 run-time membership test to ensure that the constructed object
17587 implements the target abstract interface.
17589 2006-10-31 Robert Dewar <dewar@adacore.com>
17591 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17592 Machine_Attribute pragma internally to implement the user pragma.
17593 Add processing for pragma Interface so that it is now completely
17594 equivalent to pragma Import.
17596 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17597 so that it can be applied to all entities, including record components
17598 and enumeration literals.
17599 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17600 priority ranges are correct, verify compatibility against task
17601 dispatching and locking policies, and if everything is correct an entry
17602 is added to the table containing priority specific dispatching entries
17603 for this compilation unit.
17604 (Delay_Config_Pragma_Analyze): Delay processing
17605 Priority_Specific_Dispatching pragmas because when processing the
17606 pragma we need to access run-time data, such as the range of
17607 System.Any_Priority.
17608 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17609 Allow pragma Unreferenced as a context item
17610 Add pragma Preelaborable_Initialization
17611 (Analyze_Pragma, case Interface): Interface is extended so that it is
17612 now syntactically and semantically equivalent to Import.
17613 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17614 insertion characters.
17615 Add handling for Pragma_Wide_Character_Encoding
17616 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17617 never supercedes a real restriction, and that a real restriction
17618 always supercedes a warning.
17619 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17623 Ed Schonberg <schonberg@adacore.com>
17624 Robert Dewar <dewar@adacore.com>
17626 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17627 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17628 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17630 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17631 type of the function containing a return statement, because the
17632 Return_Type field was removed. We now use the Return_Applies_To field.
17634 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17635 (Build_Task_Image_Decl): If procedure is not called from an
17636 initialization procedure, indicate that function that builds task name
17637 uses the sec. stack. Otherwise the enclosing initialization procedure
17638 will carry the indication.
17639 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17640 N_Object_Declaration instead.
17641 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17642 conditional dead code killed, and change implementation accordingly.
17643 (Insert_Actions): Add N_Return_Object_Declaration case.
17644 Correct comment to mention N_Extension_Aggregate node.
17645 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17646 attempts to save information for global variables which cannot be
17648 (Get_Current_Value_Condition): Handle conditions the other way round
17649 (constant on left). Also handle right operand of AND and AND THEN
17650 (Set_Current_Value_Condition): Corresponding changes
17651 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17652 (Get_Current_Value_Condition): Handle simple boolean operands
17653 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17654 (Get_Current_Value_Condition): If the variable reference is within an
17655 if-statement, does not appear in the list of then_statments, and does
17656 not come from source, treat it as being at unknown location.
17657 (Get_Current_Value_Condition): Enhance to allow while statements to be
17658 processed as well as if statements.
17659 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17661 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17662 of loop. This is safe now that we fixed Kill_Current_Values.
17663 (OK_To_Do_Constant_Replacement): Check whether current scope is
17664 Standard, before examining outer scopes.
17666 2006-10-31 Vincent Celier <celier@adacore.com>
17668 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17669 When True, apply VMS treatment to children of packages A, G, I and S.
17672 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17674 2006-10-31 Robert Dewar <dewar@adacore.com>
17675 Ed Schonberg <schonberg@adacore.com>
17677 * freeze.adb: Add handling of Last_Assignment field
17678 (Warn_Overlay): Supply missing continuation marks in error msgs
17679 (Freeze_Entity): Add check for Preelaborable_Initialization
17681 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17683 * g-expect.adb: Add Warnings (Off) to prevent new warning
17685 * lib-xref.adb: Add handling of Last_Assignment field
17686 (Generate_Reference): Centralize handling of pragma Obsolescent here
17687 (Generate_Reference): Accept an implicit reference generated for a
17688 default in an instance.
17689 (Generate_Reference): Accept a reference for a node that is not in the
17690 main unit, if it is the generic body corresponding to an subprogram
17693 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17695 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17697 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17699 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17700 use clauses, to avoid messages on packages used to qualify, and also
17701 to avoid messages from obsolescent units.
17702 (Warn_On_Useless_Assignments): Don't generate messages for imported
17703 and exported variables.
17704 (Warn_On_Useless_Assignments): New procedure
17705 (Output_Obsolescent_Entity_Warnings): New procedure
17706 (Check_Code_Statement): New procedure
17708 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
17709 Change name Is_Ada_2005 to Is_Ada_2005_Only
17710 (Last_Assignment): New field for useless assignment warning
17712 2006-10-31 Olivier Hainque <hainque@adacore.com>
17714 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17715 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17717 2006-10-31 Bob Duff <duff@adacore.com>
17718 Robert Dewar <dewar@adacore.com>
17719 Ed Schonberg <schonberg@adacore.com>
17721 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17722 Ada 95 mode, because it violates the new rules for AI-318.
17724 * g-awk.ads: Use overloaded subprograms in every case where we used to
17725 have a default of Current_Session. This makes the code closer to be
17726 correct for both Ada 95 and 2005.
17728 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17729 code, relying on the fact that the compiler generates a warning
17730 instead of an error in -gnatg mode.
17732 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17733 E_Return_Statement entity kind.
17734 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17736 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17737 report an error if the reserved word abstract has been previously found.
17738 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17740 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17741 parenthesized range attribute usage
17742 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17744 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17745 in the syntax for extended_return_statement. This is not in the latest
17746 RM, but the ARG is expected to issue an AI allowing this.
17747 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17748 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17749 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17750 P_Return_Statement): Parse the new syntax for extended_return_statement.
17752 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17753 Output_End_Missing): Add error-recovery code for the new
17754 extended_return_statement syntax; that is, the new E_Return entry on
17757 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17758 limited to nonlimited, because otherwise we violate the new Ada 2005
17759 rules about returning limited types in function Create_AST_Handler in
17762 * sem.adb (Analyze): Add cases for new node kinds
17763 N_Extended_Return_Statement and N_Return_Object_Declaration.
17765 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17766 type is in the same category as type of context before applying check,
17767 to prevent anomalies in instantiations.
17768 (Resolve_Aggregate): Remove test for limited components in aggregates.
17769 It's unnecessary in Ada 95, because if it has limited components, then
17770 it must be limited. It's wrong in Ada 2005, because limited aggregates
17772 (Resolve_Record_Aggregate): Move check for limited types later, because
17773 OK_For_Limited_Init requires its argument to have been resolved.
17774 (Get_Value): When copying the component default expression for a
17775 defaulted association in an aggregate, use the sloc of the aggregate
17776 and not that of the original expression, to prevent spurious
17777 elaboration errors, when the expression includes function calls.
17778 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17779 were missing. We also didn't handle qualified expressions. Now also
17780 allow function calls. Use new common routine OK_For_Limited_Init.
17781 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17782 with space can upper case letter).
17784 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17785 Has_Static_Discriminants flag
17786 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17787 type with discriminants.
17788 (Process_Range_Expr_In_Decl): Do validity checks on range
17789 (Build_Discriminant_Constraints): Use updated form of
17790 Denotes_Discriminant.
17791 (Process_Subtype): If the subtype is a private subtype whose full view
17792 is a concurrent subtype, introduce an itype reference to prevent scope
17794 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17795 Record_Type_Declaration): The functionality of the subprograms
17796 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17797 is now performed by a single routine.
17798 (Build_Derived_Record_Type): If the type definition includes an explicit
17799 indication of limitedness, then the type must be marked as limited here
17800 to ensure that any access discriminants will not be treated as having
17801 a local anonymous access type.
17802 (Check_Abstract_Overriding): Issue a detailed error message when an
17803 abstract subprogram was not overridden due to incorrect mode of its
17805 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17806 synchronized private extension declarations. Verify that the ancestor is
17807 a limited or synchronized interface or in the generic case, the ancestor
17808 is a tagged limited type or synchronized interface and all progenitors
17809 are either limited or synchronized interfaces.
17810 Derived_Type_Declaration): Check for presence of private extension when
17811 dealing with synchronized formal derived types.
17812 Process_Full_View): Enchance the check done on the usage of "limited" by
17813 testing whether the private view is synchronized.
17814 Verify that a synchronized private view is completed by a protected or
17816 (OK_For_Limited_Init_In_05): New function.
17817 (Analyze_Object_Declaration): Move check for limited types later,
17818 because OK_For_Limited_Init requires its argument to have been resolved.
17819 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17820 in order to alleviate the upward compatibility introduced by AI-318.
17821 (Constrain_Corresponding_Record): If the constraint is for a component
17822 subtype, mark the itype as frozen, to avoid out-of-scope references to
17823 discriminants in the back-end.
17824 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17825 this subprogram against wrong sources.
17826 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17827 discriminant of limited type completed with a protected type, when the
17828 discriminant is used to constrain a private component of the type, and
17829 expansion is disabled.
17830 (Find_Type_Of_Object): Do not treat a return subtype that is an
17831 anonymous subtype as a local_anonymous_type, because its accessibility
17832 level is the return type of the enclosing function.
17833 (Check_Initialization): In -gnatg mode, turn the error "cannot
17834 initialize entities of limited type" into a warning.
17835 (OK_For_Limited_Init): Return true for generated nodes, since it
17836 sometimes violates the legality rules.
17837 (Make_Incomplete_Declaration): If the type for which an incomplete
17838 declaration is created happens to be the currently visible entity,
17839 preserve the homonym chain when removing it from visibility.
17840 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17841 inherited subprograms.
17842 (Access_Definition): If this is an access to function that is the return
17843 type of an access_to_function definition, context is a type declaration
17844 and the scope of the anonymous type is the current one.
17845 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17846 incomplete subtype to the set of private dependents of the original
17848 (Constrain_Discriminated_Type): Emit an error message whenever an
17849 incomplete subtype is being constrained.
17850 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17851 corresponding subtype of the full view of the original incomplete type.
17852 (Check_Incomplete): Properly detect invalid usage of incomplete types
17855 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
17857 * g-catiio.ads, g-catiio.adb (Value): New function.
17858 Given an input String, try and parse a valid Time value.
17860 2006-10-31 Vincent Celier <celier@adacore.com>
17862 * g-debpoo.adb (Is_Valid): Correctly compute Offset using
17863 Integer_Address arithmetic, as in Set_Valid.
17865 2006-10-31 Arnaud Charlet <charlet@adacore.com>
17866 Robert Dewar <dewar@adacore.com>
17868 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
17869 handling executable extension manually and duplicating code.
17871 * make.adb: Implement new -S switch

17873 of handling executable extension manually.
17875 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
17876 is specified, the executable name ends with this suffix.
17877 Take advantage of Osint.Executable_Name instead of duplicating code.

17890 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17891 call it with -static-libgcc, as there are some platforms, such as
17892 Darwin, where one of these two switches is compulsory to link.
17894 2006-10-31 Vincent Celier <celier@adacore.com>
17896 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17897 instead of ADA_PROJECT_PATH, for the project path.
17898 (Gnatls): When displaying the project path directories, use host dir
17901 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17902 names in the project path, as absolute paths may correspond to
17903 multi-valued VMS logical names.
17905 2006-10-31 Vincent Celier <celier@adacore.com>
17907 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
17908 absolute path name.
17909 (Locate_Regular_File): Ditto
17910 (Change_Dir): Remove, no longer used

17932 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
17934 2006-10-31 Robert Dewar <dewar@adacore.com>
17936 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
17938 (Layout_Variant_Record): Retrieve the discriminants from the entity
17939 rather than from the type definition, because in the case of a full
17940 type for a private type we need to take the discriminants from the
17942 (Layout_Component_List): When applying the Max operator to variants with
17943 a nonstatic size, check whether either operand is static and scale that
17944 operand from bits to storage units before applying Max.
17945 (Layout_Type): In VMS, if a C-convention access type has no explicit
17946 size clause (and does not inherit one in the case of a derived type),
17947 then the size is reset to 32 from 64.
17949 2006-10-31 Vincent Celier <celier@adacore.com>
17951 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
17952 its file has already been loaded, according to the unit being loaded,
17953 not to the current value of Multiple_Unit_Index.
17955 2006-10-31 Thomas Quinot <quinot@adacore.com>
17956 Eric Botcazou <ebotcazou@adacore.com>
17957 Arnaud Charlet <charlet@adacore.com>
17959 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
17960 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if

17983 * mlib-utl.adb (Initialized): Remove, no longer used
17984 (Initialize): Remove, no longer used
17985 (Ar): If Ar_Exec is null, get the location of the archive builder and,

17988 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
17991 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17993 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
17994 Process_Body_Clauses): If the context of a body includes a use clause
17995 for P.Q then a with_clause for P in the same body is not redundant,
17996 even if the spec also has a with_clause on P.
17997 Add missing continuation mark to error msg
17998 (Build_Limited_Views): A limited view of a type is tagged if its
17999 declaration includes a record extension.
18000 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18001 node, even if the subunit has errors. This avoids malfunction by
18002 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18003 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18004 generation of obsolescent messages for with statements (cannot do
18005 this too early, or we cannot implement avoiding the messages in the
18006 case of obsolescent units withing obsolescent units).
18007 (Install_Siblings): If the with_clause is on a remote descendant of
18008 an ancestor of the current compilation unit, find whether there is
18009 a sibling child unit that is immediately visible.
18010 (Remove_Private_With_Clauses): New procedure, invoked after completing
18011 the analysis of the private part of a nested package, to remove from
18012 visibility the private with_clauses of the enclosing package
18014 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18015 now centralized in Generate_Reference.
18016 (Install_Limited_Context_Clauses): Remove superfluous error
18017 message associated with unlimited view visible through use
18018 and renamings. In addition, at the point in which the error
18019 is reported, we add the backslash to the text of the error
18020 to ensure that it is reported as a single error message.
18021 Use new // insertion for some continuation messages
18022 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18023 to create implicit with_clause for parent unit mentioned in original
18024 limited_with_clause.
18025 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18026 unit is a child unit. For ASIS queries.
18027 (Analyze_Subunit): If the subunit appears within a child unit, make all
18028 ancestor child units directly visible again.

18043 a formal object declaration with an access definition or a subtype mark
18044 with a null exclusion.
18045 (P_Generic_Association): Handle association with box, and others_choice
18046 with box, to support Ada 2005 partially parametrized formal packages.
18048 2006-10-31 Robert Dewar <dewar@adacore.com>
18049 Javier Miranda <miranda@adacore.com>
18051 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18052 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18053 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18054 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18055 private extensions.
18056 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18057 to P_Interface_Type_Definition.
18058 (P_Interface_Type_Definition): Addition of one formal to report an error
18059 if the reserved word abstract has been previously found.
18060 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18061 object renaming declaration with an access definition or subtype mark
18062 with a possible null exclusion.

18081 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18084 2006-10-31 Vincent Celier <celier@adacore.com>
18086 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18087 on VMS, change "__" to '.' before checking the name.
18088 (Record_Ada_Source): Always add the source file name in the list of
18089 of sources, even if it is not the first time, as it is for another
18091 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18092 dot, instead of replacing only the first '_'.
18094 * prj-part.adb (Parse): Convert project file path to canonical form
18096 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18097 extended, the project id of the project extending it is recorded in its
18098 data, even when it has already been processed as an imported project.
18100 2006-10-31 Robert Dewar <dewar@adacore.com>
18102 * repinfo.adb (List_Entities): Don't list entities from renaming
18105 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18106 Robert Dewar <dewar@adacore.com>
18108 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18109 only a restriction warning is active for the given restriction. This is
18110 desirable because we do not want to modify code in the case where only
18112 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18113 causes overriding of real restrictions.
18114 Take advantage of new No_Restrictions constant.
18116 * raise.h: (__gnat_set_globals): Change profile.
18118 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18120 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18123 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18124 Move all the entities in obsolete package System.PolyORB_Interface to
18125 System.Partition_Interface.
18126 (RE_Storage_Size): New function in System.Tasking.

18139 Thomas Quinot <quinot@adacore.com>
18140 Javier Miranda <miranda@adacore.com>
18141 Gary Dismukes <dismukes@adacore.com>
18143 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18144 properly an attempt to apply Unchecked_Access to a protected operation.
18145 (OK_Self_Reference): New subprogram to check the legality of an access
18146 attribute whose prefix is the type of an enclosing aggregate.
18147 Generalizes previous mechanism to handle attribute references nested
18148 arbitrarily deep within the aggregate.
18149 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18150 can appear in an aggregate if this is a default-initialized aggregate
18151 for a self-referential type.
18152 (Resolve_Attribute, case Access): Ditto.
18153 Add support for new implementation defined attribute Stub_Type.
18154 (Eval_Attribute, case Attribute_Stub_Type): New case.
18155 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18156 (Stream_Attribute_Available): Implement using new subprogram from
18157 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18158 Has_Specified_Stream_Attribute flag.
18159 Disallow Storage_Size and Storage_Pool for access to subprogram
18160 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18161 access types of return subtypes in extended return statements. Remove
18162 accessibility checks on anonymous access types when Unchecked_Access is
18164 (Analyze_Attribute): Add support for the use of 'Class to convert
18165 a class-wide interface to a tagged type.
18166 Add support for the attribute Priority.
18167 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18168 whether the designated type is discriminated with a constrained partial
18169 view and require static matching in that case.
18170 Add local variable Des_Btyp. The Designated_Type
18171 of an access to incomplete subtype is either its non-limited view if
18172 coming from a limited with or its etype if regular incomplete subtype.
18174 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18175 Fix predicate to identify and allow cases of (expander-generated)
18176 references to tag of designated object of a RACW.
18177 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18178 non-static, and therefore cannot appear as a primary in a preelaborable
18180 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18181 Has_Read_Write_Attributes.
18182 (Has_Read_Write_Attributes): Reimplement in termes of
18183 Has_Stream_Attribute_Definition.
18184 (Missing_Read_Write_Attributes): When checking component types in a
18185 record, unconditionally call Missing_Read_Write_Attributes recursively
18186 (remove guard checking for Is_Record_Type / Is_Access_Type).
18188 2006-10-31 Robert Dewar <dewar@adacore.com>
18190 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18191 useless assignments here and conditionalize it on absence of exception
18193 (Analyze_Exception_Handlers): Small code reorganization of error
18194 detection code, for new handling of formal packages.
18196 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18197 Hristian Kirtchev <kirtchev@adacore.com>
18199 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18200 that has been constant-folded, preserve information of original tree,
18202 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18203 generated private extension declaration if the formal derived type is
18204 synchronized. Carry synchronized present over to the generated private
18206 (Validate_Derived_Type_Instance): Ensure that the actual of a
18207 synchronized formal derived type is a synchronized tagged type.
18208 (Instantiate_Formal_Package): When creating the instantiation used to
18209 validate the actual package of a formal declared without a box, check
18210 whether the formal itself depends on a prior actual.
18211 (Instantiate_Formal_Subprogram): Create new entities for the defining
18212 identifiers of the formals in the renaming declaration, for ASIS use.
18213 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18214 a renaming declaration or a subtype declaration for an actual in an
18215 instance, capture location information of declaration in generic, for
18217 (Instantiate_Formal_Package): Add comments on needed additional tests.
18218 AI-317 (partial parametrization) is fully implemented.
18219 (Validate_Private_Type_Instance): Add check for actual which
18220 must have preelaborable initialization
18221 Use new // insertion for some continuation messages
18222 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18223 Default_Expression. Add type retrieval when the declaration has an
18224 access definition. Update premature usage of incomplete type check.
18225 (Check_Access_Definition): New subsidiary routine. Check whether the
18226 current compilation version is Ada 05 and the supplied node has an
18228 (Instantiate object): Alphabetize local variables. Handle the creation
18229 of new renaming declarations with respect to the kind of definition
18230 used - either an access definition or a subtype mark. Guard against
18231 unnecessary error message in the context of anonymous access types after
18232 they have been resolved. Add check for required null exclusion in a
18233 formal object declaration.
18234 (Switch_View): A private subtype of a non-private type needs to be
18235 switched (the base type can have been switched without its private
18236 dependents because of the last branch of Check_Private_View.
18237 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18239 (Instantiate_Type): Emit an error message whenever a class-wide type of
18240 a tagged incomplete type is used as a generic actual.
18241 (Find_Actual_Type): Extend routine to handle a component type in a child
18242 unit that is imported from a formal package in a parent.
18243 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18244 agree on constrainedness, rather than checking against ultimate ancestor
18245 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18246 generic body, for navigation purposes.
18248 2006-10-31 Robert Dewar <dewar@adacore.com>
18249 Thomas Quinot <quinot@adacore.com>
18251 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18253 (New_Stream_Subprogram): When processing an attribute definition clause
18254 for a stream-oriented subprogram, record an entity node occurring at
18255 the point of clause to use for checking the visibility of the clause,
18256 as defined by 8.3(23) as amended by AI-195.
18257 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18258 New_Stream_Function and New_Stream_Procedure.
18259 (New_Stream_Function, New_Stream_Procedure): Removed.
18260 (Analyze_Attribute_Definition_Clause, case Address): Check new
18261 Alignment_Check check
18263 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18264 Javier Miranda <miranda@adacore.com>
18265 Robert Dewar <dewar@adacore.com>
18267 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18268 generate the same errors compiling under -gnatc.
18269 (Try_Object_Operation): If no candidate interpretation succeeds, but
18270 there is at least one primitive operation with the right name, report
18271 error in call rather than on a malformed selected component.
18272 (Analyze_Selected_Component): If the prefix is an incomplete type from
18273 a limited view, and the full view is available, use the full view to
18274 determine whether this is a prefixed call to a primitive operation.
18275 (Operator_Check): Verify that a candidate interpretation is a binary
18276 operation before checking the type of its second formal.
18277 (Analyze_Call): Add additional warnings for function call contexts not
18279 (Analyze_Allocator): Move the check for "initialization not allowed for
18280 limited types" after analyzing the expression. This is necessary,
18281 because OK_For_Limited_Init looks at the structure of the expression.
18282 Before analysis, we don't necessarily know what sort of expression it
18283 is. For example, we don't know whether F(X) is a function call or an
18284 indexed component; the former is legal in Ada 2005; the latter is not.
18285 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18286 were missing. We also didn't handle qualified expressions. Now also
18287 allow function calls. Use new common routine OK_For_Limited_Init.
18288 (Analyze_Type_Conversion): Do not perform some legality checks in an
18289 instance, because the error message will be redundant or spurious.
18290 (Analyze_Overloaded_Selected_Component): Do not do style check when
18291 setting an entity, since we do not know it is the right entity yet.
18292 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18293 (Analyze_Overloaded_Selected_Component): Same change
18294 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18295 since regular incomplete subtypes are transformed into corresponding
18296 subtypes of their full views.
18297 (Complete_Object_Operation): Treat name of transformed subprogram call
18298 as coming from source, for browsing purposes.
18299 (Try_Primitive_Operation): If formal is an access parameter, compare
18300 with base type of object to determine whether it is a primitive
18302 (Operator_Check): If no interpretation of the operator matches, check
18303 whether a use clause on any candidate might make the operation legal.
18304 (Try_Class_Wide_Operation): Check whether the first parameter is an
18305 access type whose designated type is class-wide.

18312 warn on infinite loops.
18313 Add \\ to some continuation messages
18314 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18315 (Process_Bounds): If the bounds are integer literals that result from
18316 constant-folding, and they carry a user-defined type, preserve that type
18317 rather than treating this as an integer range.
18318 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18319 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18320 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18321 left hand side of assignment.
18322 (Analyze_Assignment): Add suport to manage assigments to the attribute
18323 priority of a protected object.
18324 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18325 not just identifiers.
18326 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18327 or AND THEN for possible tracking.
18328 (Analyze_Iteration_Scheme): Check for setting Current_Value for the

18333 Bob Duff <duff@adacore.com>
18335 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18336 procedure cannot be a protected operation (it is a basic_declaration,
18337 not a subprogram_declaration).
18338 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18339 Subp. Add logic for entry processing.
18340 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18341 Determine whether an entry or subprogram of a protected or task type
18342 override an inherited primitive of an implemented interface.
18343 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18344 Update the actual used in calls to Check_Overriding_Indicator.
18345 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18346 generate the proper reference to the parent unit, for cross-reference.
18347 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18349 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18350 (Add_Extra_Formal): Revise procedure to allow passing in associated
18351 entity, scope, and name suffix, and handle setting of the new
18352 Extra_Formals field.
18353 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18354 pass new parameters. Add support for adding the new extra access formal
18355 for functions whose calls are treated as build-in-place.
18356 (Analyze_A_Return_Statement): Correct casing in error message.
18357 Move Pop_Scope to after Analyze_Function_Return, because an extended
18358 return statement really is a full-fledged scope. Otherwise, visibility
18359 doesn't work right. Correct use of "\" for continuation messages.
18360 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18361 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18362 the node doesn't get properly marked as analyzed.
18363 (Analyze_Subprogram_Body): If subprogram is a function that returns
18364 an anonymous access type that denotes a task, build a Master Entity
18366 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18367 proper usage of null exclusion in a result definition.
18368 (Process_Formals): Code cleanup and new error message.
18369 (Process_Formals): Detect incorrect application of null exclusion to
18371 (Conforming_Types): Handle conformance between [sub]types and itypes
18372 generated for entities that have null exclusions applied to them.
18373 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18374 base type is an access subtype. This case arrises with null exclusions.
18375 (New_Overloaded_Entity): Do not remove the overriden entity from the
18376 homonym chain if it corresponds with an abstract interface primitive.
18377 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18378 call to the synthesized predicate Is_Incomplete_Type.
18379 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18381 (Analyze_Subprogram_Declaration): Check that abstract interface
18382 primitives are abstract or null.
18383 (Analyze_Subprogram_Specification): Remove previous check for abstract
18384 interfaces because it was not complete.
18385 (Has_Interface_Formals): Removed.

18388 Javier Miranda <miranda@adacore.com>
18390 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18391 of Analyze_Package_Body, to create Itype references for anonymous
18392 access types created in the package declaration, whose designated types
18393 may have only a limited view.
18394 (Analyze_Package_Specification): For the private part of a nested
18395 package, install private_with_clauses of enclosing compilation unit if
18396 we are in its visible part.
18397 (Declare_Inherited_Private_Subprograms): Complete barrier
18398 to ensure that the primitive operation has an alias to some parent
18399 primitive. This is now required because, after the changes done for the
18400 implementation of abstract interfaces, the contents of the list of
18401 primitives has entities whose alias attribute references entities of
18402 such list of primitives.
18403 (Analyze_Package_Specification): Simplify code that handles parent units
18404 of instances and formal packages.
18405 (Uninstall_Declarations): Check the convention consistency among
18406 primitive overriding operations of a tagged record type.

18415 expected and found set right)
18416 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18417 (Analyze_Generic_Renaming): Same fix
18418 (Use_One_Package): Do not take into account the internal entities of
18419 abstract interfaces during the analysis of entities that are marked
18420 as potentially use-visible.
18421 (Find_Type): Handle the case of an attribute reference for
18422 implementation defined attribute Stub_Type (simply let the analysis of
18423 the attribute reference rewrite it).
18424 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18425 type that appears in a Use_Type clause.
18426 (Analyze_Object_Renaming): Add support for renaming of the Priority
18428 (Find_Type): In Ada 2005, a task type can be used within its own body,
18429 when it appears in an access definition.
18430 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18431 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18432 in a formal object declaration or in a subtype declaration.
18433 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18434 (Check_Null_Exclusion): New local routine to
18435 Analyze_Subprogram_Renaming. Check whether the formals and return
18436 profile of a renamed subprogram have required null exclusions when
18437 their counterparts of the renaming already impose them.
18438 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18439 Determine whether an entity is inside a generic scope.
18440 (In_Open_Scope): First pass of documentation update.
18441 (Find_Expanded_Name): Add support for shadow entities associated with
18442 limited withed packages. This is required to handle nested packages.
18443 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18444 that makes a renaming of a limited withed package illegal.
18446 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18447 Ed Schonberg <schonberg@adacore.com>
18449 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18450 Check_Overriding_Indicator.
18451 (Analyze_Task_Definition): Ditto.
18452 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18453 (Check_Overriding_Indicator): To find overridden interface operation,
18454 examine only homonyms that have an explicit subprogram declaration, not
18455 inherited operations created by an unrelated type derivation.
18456 (Check_Overriding_Indicator): When checking for the presence of "null"
18457 in a procedure, ensure that the queried node is a procedure
18459 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18460 type when the formal is an access to variable.
18461 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18462 (Analyze_Task_Type): Same addition
18463 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
18464 provide navigation capabilities for entries.
18466 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18467 Ed Schonberg <schonberg@adacore.com>
18468 Javier Miranda <miranda@adacore.com>
18469 Gary Dismukes <dismukes@adacore.com>
18471 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18472 inherited from an interface ancestor by another interface in the
18473 context of an instance as 'late'.
18474 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18475 of a call to a function that dispatches on access result.
18476 (Check_Dispatching_Operation): In case of late overriding of a primitive
18477 that covers abstract interface subprograms we register it in all the
18478 secondary dispatch tables associated with abstract interfaces.
18479 (Check_Dispatching_Call): Add check that a dispatching call is not made
18480 to a function with a controlling result of a limited type. This is a
18481 current implementation restriction.
18482 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18483 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18484 argument is an interface type that is a generic formal.
18485 (Is_Interface_Subprogram): Removed.
18486 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18487 operation, check the formals to handle the case in which it is
18488 associated with an abstract interface type.
18490 2006-10-31 Robert Dewar <dewar@adacore.com>
18491 Ed Schonberg <schonberg@adacore.com>

18501 Current_Value in the conditional case, to evaluate additional
18502 comparisons at compile time.
18504 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18505 Hristian Kirtchev <kirtchev@adacore.com>
18506 Javier Miranda <miranda@adacore.com>
18508 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18509 subprogram type to provide better diagnostics in case of ambiguity.
18510 (Covers): Handle coverage of formal and actual anonymous access types in
18511 the context of generic instantiation.
18512 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18513 abstract interface types; this is required to handle concurrent types
18514 with discriminants and abstract interface types.

18528 Add missing continuation marks in error msgs
18529 (Unqualify): New function for removing zero or more levels of
18530 qualification from an expression. There are numerous places where this
18531 ought to be used, but we currently only deal properly with zero or one
18533 (In_Instance); The analysis of the actuals in the instantiation of a
18534 child unit is not within an instantiation, even though the parent
18535 instance is on the scope stack.
18536 (Safe_To_Capture_Value): Exclude the case of variables that are
18538 (Check_Obsolescent): Removed
18539 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

18541 object in an assignment.
18542 (Get_Subprogram_Entity): New function
18543 (Known_To_Be_Assigned): New function

18552 Change Is_Lvalue to May_Be_Lvalue
18553 (May_Be_Lvalue): Extensive additional code to deal with subprogram
18554 arguments (IN parameters are not Lvalues, IN OUT parameters are).
18555 (Safe_To_Capture_Value): Extend functionality so it can be used for
18556 the current value condition case.
18557 (Has_Compatible_Alignment): New function
18558 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
18559 objects to handle the Ada 2005 case, where aliasedness no longer implies
18560 that the object is constrained. In particular, for dereferenced names,
18561 the designated object must be assumed to be unconstrained.
18562 (Kill_Current_Values): Properly deal with the case where we encounter
18563 a loop in the scope chain.

18580 Suppresses warning, and seems appropriate in any case
18582 * s-osinte-vms.adb: Add Volatile to Asm statement

18607 N_Extended_Return_Statement.
18608 (Procedure_To_Call): Move to a different place to make room in
18609 N_Extended_Return_Statement.
18610 (Return_Type): Removed this field to make room in return statements
18612 (Return_Statement_Entity): New field in return statements, in part to
18613 replace Return_Type, and in part to support the fact that return
18614 statements are now pushed on the scope stack during semantic analysis.
18615 (Return_Object_Declarations): New field to support extended return
18617 (N_Extended_Return_Statement): New node for extended_return_statement
18619 (N_Return_Object_Declaration): New node for part of
18620 extended_return_statement nonterminal. Needed because all the necessary
18621 fields won't fit in N_Extended_Return_Statement.

18641 print null exclusion twice in the case of an access definition,
18642 Implement new -gnatL switch

18644 N_Object_Declaration instead. Implement the case for
18645 N_Extended_Return_Statement. Alphabetize the cases.
18646 Add cases for new nodes N_Extended_Return_Statement and
18647 N_Return_Object_Declaration. The code is not yet written.

18701 2006-10-31 Olivier Hainque <hainque@adacore.com>
18703 * s-stchop.ads: make this unit preelaborate. This is desirable in
18704 general and made mandatory by the use of this unit by s-taprop which
18705 is itself preelaborate.
18707 * s-stchop-vxworks.adb (Set_Stack_Info, Task_Descriptor type): Add
18708 Td_Events component.

18791 2006-10-31 Pat Rogers <rogers@adacore.com>
18793 * a-rttiev.ads, a-rttiev.adb:
18794 This is a significant redesign primarily for the sake of automatic
18795 timer task termination but also to fix a design flaw.
18796 Therefore we are now using an RTS lock, instead of a protected
18797 object, to provide mutual exclusion to the queue of pending events
18798 and the type Timing_Event is no longer a protected type.

19538 standard ASCII characters. So the length of the directory entry is now
19539 returned from the imported __gnat_readdir routine.
19540 Update copyright notice.

19588 with small changes.
19591 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
19592 variable with the expression being built, only its inner field.

19646 other basic tools. The full version that includes the Ada 2005 stuff
19647 is in separate files a-except-2005.ads/adb. The reason is that we do
19648 not want to cause bootstrap problems with compilers not recognizing
19650 Add exception reason code PE_Implicit_Return

19973 positive. Also add checks against invalid values, and support for kb,
19974 mb. Ditto for -D switch.
19976 2006-02-13 Robert Dewar <dewar@adacore.com>
19977 Serguei Rybin <rybin@adacore.com>
19979 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
19980 save/restore routines.
19981 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

19983 Since we are changing the tree format anyway, also get rid of the
19984 junk obsolete Immediate_Errors flag.
19985 (Tree_Read): Change the way of reading Tree_Version_String - now we
19986 read the version string from the tree even if its length is not the
19987 same as the length of the version string computed from Gnatvsn.

20050 are of equal length and have the same start and end values.
20051 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20052 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20053 aggregate when it is part of an object declaration.
20054 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20055 constrains discriminants of its parent, add explicitly the discriminant
20056 constraints of the ancestor by retrieving them from the

20059 2006-02-13 Robert Dewar <dewar@adacore.com>
20061 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20062 attribute Mechanism_Code is applied to renamed subprogram, modify
20063 prefix to point to base subprogram.
20064 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20066 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20067 renamed subprograms so that the front-end must replace the prefix
20070 2006-02-13 Javier Miranda <miranda@adacore.com>
20071 Gary Dismukes <dismukes@adacore.com>
20073 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20074 availability of RE_Interface_Tag.
20075 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20076 (Freeze_Record_Type): Do not generate the tables associated with
20077 timed and conditional dispatching calls through synchronized
20078 interfaces if compiling under No_Dispatching_Calls restriction.
20079 When compiling for Ada 2005, for a nonabstract
20080 type with a null extension, call Make_Controlling_Function_Wrappers
20081 and insert the wrapper function declarations and bodies (the latter
20082 being appended as freeze actions).
20083 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20084 predefined primitives associated with timed and conditional
20085 dispatching calls through synchronized interfaces if we are
20086 compiling under No_Dispatching_Calls.
20087 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20088 service is available before generating a call.
20089 (Make_Controlling_Function_Wrappers): New procedure.
20090 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20091 access-to-limited-interfaces because they can be used to reference
20092 tasks that implement such limited interface.
20093 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20094 procedure spec and body of the Offset_To_Top function that is generated
20095 when the parent of a type with discriminants has secondary dispatch
20097 (Init_Secondary_Tags): Handle the case in which the parent of the type
20098 containing secondary dispatch tables has discriminants to generate the
20099 correct arguments to call Set_Offset_To_Top.
20100 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20102 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20103 Add Wide_[Wide_]Expanded_Name.
20104 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20105 the same functionality of Get_Prim_Op_Address but applied to predefined
20106 primitive operations because the pointers to the predefined primitives
20107 are now saved in a separate table.
20108 (Parent_Size): Modified to get access to the separate table of primitive
20109 operations or the parent type.
20110 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20111 functionality of Set_Prim_Op_Address but applied to predefined primitive
20113 (Set_Signature): New subprogram used to store the signature of a DT.
20114 (Displace): If the Offset_To_Top value is not static then call the
20115 function generated by the expander to get such value; otherwise use
20116 the value stored in the table of interfaces.
20117 (Offset_To_Top): The type of the actual has been changed to Address to
20118 give the correct support to tagged types with discriminants. In this
20119 case this value is stored just immediately after the tag field.
20120 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20121 offset_to_top value is static and hence pass this value to the run-time
20122 to store it in the table of interfaces, or else if this value is dynamic
20123 and then pass to the run-time the address of a function that is
20124 generated by the expander to provide this value for each object of the
20127 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20128 (Default_Prim_Op_Count): New entity

20137 Make_Adjust_Call done for a newly-allocated object.
20139 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20140 in a subprogram are wrapped in a cleanup block, indicate that the
20141 subprogram contains an inner block with an exception handler.
20142 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20143 Adjust call is for a newly-allocated object. In that case we must not
20144 assume that the finalization list chain pointers are correct (since they
20145 come from a bit-for-bit copy of the original object's pointers) so if
20146 the attach level would otherwise be zero (no change), we set it to 4
20147 instead to cause the pointers to be reset to null.
20149 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20150 reset chain pointers to null.
20152 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20154 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20155 string, and the context requires a loop for the assignment (e.g.
20156 because the left-hand side is packed), generate a unique name for the
20157 temporary that holds the string, to prevent spurious name clashes.
20159 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20160 Javier Miranda <miranda@adacore.com>
20161 Robert Dewar <dewar@adacore.com>
20162 Gary Dismukes <dismukes@adacore.com>
20164 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20165 return unconstrained arrays.
20167 (Expand_Call): An indirect call through an access parameter of a
20168 protected operation is not a protected call.
20169 Add circuit to raise CE in Ada 2005 mode following call
20170 to Raise_Exception.
20171 (Register_DT_Entry): Do nothing if
20172 the run-time does not give support to abstract interfaces.
20173 (Freeze_Subprogram): In case of dispatching operations, do not generate
20174 code to register the operation in the dispatch table if the source
20175 is compiled with No_Dispatching_Calls.
20176 (Register_Predefined_DT_Entry): Generate code that calls the new
20177 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20178 Set_Prim_Op_Address.
20180 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20181 on array assignments if the right-hand side is a function call that has
20182 been inlined. Check is performed on the assignment in the block.
20183 (Process_Bounds): If bounds and range are overloaded, apply preference
20184 rule for root operations to disambiguate, and diagnose true ambiguity.
20185 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20186 a tag-indeterminate right-hand side even when Expander_Active is True.
20187 Needed to ensure that dispatching calls to T'Input are allowed and
20188 get the tag of the target class-wide object.
20190 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20191 an inherited primitive operation that already overrides several
20192 abstract interface primitives. For transitivity, the new entity must
20193 also override all the abstract interface primitives covered by the
20194 inherited overriden primitive.
20195 Emit warning if new entity differs from homograph in same scope only in
20196 that one has an access parameter and the other one has a parameter of
20197 a general access type with the same designated type, at the same
20198 position in the signature.
20199 (Make_Inequality_Operator): Use source locations of parameters and
20200 subtype marks from corresponding equality operator when creating the
20201 tree structure for the implicit declaration of "/=". This does not
20202 change anything in behaviour except that the decoration of the
20203 components of the subtree created for "/=" allows ASIS to get the
20204 string images of the corresponding identifiers.
20205 (Analyze_Return_Statement): Remove '!' in warning message.
20206 (Check_Statement_Sequence): Likewise.
20207 (Analyze_Subprogram_Body): For an access parameter whose designated type
20208 is an incomplete type imported through a limited_with clause, use the
20209 type of the corresponding formal in the body.
20210 (Check_Returns): Implicit return in No_Return procedure now raises
20211 Program_Error with a compile time warning, instead of beging illegal.
20212 (Has_Single_Return): Function returning unconstrained type cannot be
20213 inlined if expression in unique return statement is not an identifier.
20214 (Build_Body_To_Inline): It is possible to inline a function call that
20215 returns an unconstrained type if all return statements in the function
20216 return the same local variable. Subsidiary procedure Has_Single_Return
20217 verifies that the body conforms to this restriction.
20219 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20220 same type, and one of them is of an anonymous access type, convert
20221 the other operand to it, so that this is a valid binary operation for
20223 (Resolve_Type_Conversion): Handle subtypes of protected types and
20224 task types when accessing to the corresponding record type.
20225 (Resolve_Allocator): Add '\' in 2-line warning message.
20226 Remove '!' in warning message.
20227 (Resolve_Call): Add '\' in 2-line warning message.
20228 (Valid_Conversion): Likewise.
20229 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20230 resulting type may be an access type with an implicit dereference.
20231 Obtain the proper component from the designated type.
20232 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20233 given by an expanded name with prefix Standard, when the operands are
20234 of an anonymous access type.
20235 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20236 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20237 prefix of the expression is not of an incomplete type. Allows full
20238 diagnoses of all semantic errors.
20239 (Resolve_Actuals): If the actual is an allocator whose directly
20240 designated type is a class-wide interface we build an anonymous
20241 access type to use it as the type of the allocator. Later, when
20242 the subprogram call is expanded, if the interface has a secondary
20243 dispatch table the expander will add a type conversion to force
20244 the displacement of the pointer.
20245 (Resolve_Call): If a function that returns an unconstrained type is
20246 marked Inlined_Always and inlined, the call will be inlined and does
20247 not require the creation of a transient scope.
20248 (Check_Direct_Boolean_Op): Removed
20249 (Resolve_Comparison_Op): Remove call to above
20250 (Resolve_Equality_Op): Remove call to above
20251 (Resolve_Logical_Op): Inline above, since this is only call.
20252 (Valid_Conversion): Handle properly conversions between arrays of
20253 convertible anonymous access types.
20256 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20257 the literal in an unchecked conversion, because GCC 4.x needs a static
20258 value for a string bound.
20260 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20261 Hristian Kirtchev <kirtchev@adacore.com>
20263 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20264 components of the corresponding record, take into account component
20265 definitions that are access definitions.
20266 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20267 procedure is not considered a dispatching call and will be expanded
20270 2006-02-13 Javier Miranda <miranda@adacore.com>
20272 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20273 controlling argument of the dispatching call is an abstract interface
20274 class-wide type then we use it directly.
20275 Check No_Dispatching_Calls restriction.
20276 (Default_Prim_Op_Position): Remove the code that looks for the last
20277 entity in the list of aliased subprograms. This code was wrong in
20279 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20280 when the source is compiled with the No_Dispatching_Calls restriction.
20281 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20282 if we are compiling with restriction No_Dispatching_Calls.
20283 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20284 subprograms if we are compiling under No_Dispatching_Calls restriction.
20285 (Make_DT): Generate a dispatch table with a single dummy entry if
20286 we are compiling with the No_Dispatching_Calls restriction. In
20287 addition, in this case we don't generate code that calls to the
20288 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20289 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20290 of this subprogram if compiling with the No_Dispatching_Calls
20292 (Expand_Type_Conversion): Instead of using the actual parameter,
20293 the argument passed as parameter to the conversion function was
20294 erroneously referenced by the expander.
20295 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20296 Set_Predefined_Primitive_Op_Address and Set_Signature.
20297 (Expand_Dispatching_Call): Generate call to
20298 Get_Predefined_Prim_Op_Address for predefined primitives.
20299 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20300 predefined primitives.
20301 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20302 primitives we reserve one dummy entry to ensure that the tag does not
20303 point to some memory that is associated with some other object. In
20304 addition, remove all the old code that generated the assignments
20305 associated with the signature of the dispatch table and replace them
20306 by a call to the new subprogram Set_Signature.
20307 (Set_All_DT_Position): Change the algorithm because now we have a
20308 separate dispatch table associated with predefined primitive operations.
20309 (Expand_Interface_Conversion): In case of non-static offset_to_top
20310 add explicit dereference to get access to the object after the call
20311 to displace the pointer to the object.
20312 (Expand_Interface_Thunk): Modify the generation of the actual used
20313 in the calls to the run-time function Offset_To_Top to fulfil its
20315 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.

20319 * exp_dist.adb (Copy_Specification): For access parameters, copy
20320 Null_Exclusion flag, which will have been set for stream subprograms
20323 2006-02-13 Pascal Obry <obry@adacore.com>
20325 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20326 previous implementation was using the C runtime spawnve routine but
20327 the corresponding wait was using directly the Win32 API. This was
20328 causing some times a lock when waiting for an event using
20329 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20330 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20331 API fixes this problem.
20333 2006-02-13 Robert Dewar <dewar@adacore.com>
20335 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20342 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
20343 array reference that is an explicit dereference, mark the converted
20344 (packed) array reference as analyzed to prevent a forthcoming
20345 reanalysis from resetting its type to the original (non-packed) array

20349 Javier Miranda <miranda@adacore.com>
20350 Eric Botcazou <ebotcazou@adacore.com>
20352 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20353 Is_Predefined_Primitive_Operation): When
20354 searching for the predefined equality operator, verify that operands
20355 have the same type.
20356 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20357 for the last entity in the list of aliased subprograms. This code
20358 was wrong in case of renamings.
20359 (Set_Renamed_Subprogram): New procedure
20360 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20361 Exp_Type constant computed when entering this subprogram.
20362 (Known_Null): New function
20363 (OK_To_Do_Constant_Replacement): New function
20364 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20365 (Side_Effect_Free): An attribute reference 'Input is not free of
20366 side effect, unlike other attributes that are functions. (from code
20368 (Remove_Side_Effects): Expressions that involve packed arrays or records
20369 are copied at the point of reference, and therefore must be marked as
20370 renamings of objects.
20371 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20372 not a dispatching operation.
20375 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20376 elementary types in all cases.
20378 2006-02-13 Javier Miranda <miranda@adacore.com>

20381 task types when accessing to the corresponding record type.
20382 Remove '!' in warning message.
20384 2006-02-13 Olivier Hainque <hainque@adacore.com>
20386 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20387 to avoid useless and space inefficient overalignments on targets where
20388 Max_Alignment is larger than 16.
20390 2006-02-13 Pascal Obry <obry@adacore.com>
20392 * g-catiio.adb (Sec_Number): New type used to compute the number of
20393 seconds since 1-1-1970.
20394 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20395 negative numbers (years, months...) it is better to have a Natural here.
20397 (Image) [Number]: Change parameter from Long_Integer to Number.
20398 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20399 overflow for dates past year 2038.
20401 2006-02-13 Matthew Heaney <heaney@adacore.com>
20403 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20406 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20408 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20410 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20411 finalization can occur normally.
20413 2006-02-13 Vincent Celier <celier@adacore.com>
20415 * gnatcmd.adb (Rules_Switches): New table
20416 (Add_To_Rules_Switches): New procedure
20417 (GNATCmd): For command CHECK, put all options following "-rules" in the
20418 Rules_Switches table. Append these -rules switches after the -cargs
20421 2006-02-13 Robert Dewar <dewar@adacore.com>
20423 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20424 These two cases were generating incorrect output, and if this unit
20425 was built with checks on, generated a discriminant mismatch constraint
20428 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20429 Robert Dewar <dewar@adacore.com>
20431 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20432 view is an array type, indicate the component type as well, for
20433 navigation purposes.
20434 (Generate_Reference): Don't consider array ref on LHS to be a case
20435 of violating pragma Unreferenced.
20436 Do not give Ada 2005 warning except on real reference.
20438 2006-02-13 Vincent Celier <celier@adacore.com>
20440 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20441 main source, add switch -mdebug-main=_ada_ so that the executable can
20442 be debugged by the standard VMS debugger.
20443 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20444 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20445 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20446 of the last source, as the binding and linking phases are never
20448 Set all executable obsolete when rebuilding a library.
20450 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20453 2006-02-13 Javier Miranda <miranda@adacore.com>
20456 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20457 code to improve the error message reported when the program has
20458 declarations of abstract interface types and it is not compiled with
20459 the -gnat05 switch.
20460 (P_Access_Definition): Reorganize the code to improve the error
20461 message reported when the new Ada 2005 syntax for anonymous
20462 access types is used and the program is not compiled with the

20479 the standard naming data.
20481 2006-02-13 Vincent Celier <celier@adacore.com>
20483 * prj.ads (Error_Warning): New enumeration type
20485 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20486 unknown, use the location of the project to report the error.
20487 (When_No_Sources): New global variable
20488 (Report_No_Ada_Sources): New procedure
20489 (Check): New parameter When_No_Sources. Set value of global variable

20493 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20496 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20497 Call Prj.Proc.Process with parameter When_No_Sources.
20499 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20500 Call Recursive_Check with parameter When_No_Sources.
20501 (Recursive_Check): New parameter When_No_Sources. Call itself and
20502 Prj.Nmsc.Check with parameter When_No_Sources.
20503 (Process): New parameter When_No_Sources. Call Check with parameter

20515 When removing nodes (attributes Source_Dirs, Source_Files,
20516 Source_List_File and package Naming), save the comments and attach the
20517 saved comments to the newly created nodes.
20518 Do not add a with clause for the naming package if one already exists.

20526 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
20527 aliased entities to look for the overriden abstract interface
20529 (Is_Interface_Subprogram): Complete documentation.
20530 (Check_Dispatching_Operation): Do not generate code to register the
20531 operation in the dispatch table if the source is compiled with
20532 restriction No_Dispatching_Calls.
20533 (Override_Dispatching_Operation): Check for illegal attempt to override
20534 No_Return procedure with procedure that is not No_Return
20535 (Check_Dispatching_Call): Suppress the check for an abstract operation
20536 when the original node of an actual is a tag-indeterminate attribute
20537 call, since the attribute, which must be 'Input, can never be abstract.
20538 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20539 call to the Input attribute (even when rewritten).
20540 (Propagate_Tag): Augment comment to indicate the possibility of a call
20541 to an Input attribute.
20543 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20544 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
20546 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
20547 No_Wide_Characters is no longer partition-wide
20548 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
20551 2006-02-13 Douglas Rupp <rupp@adacore.com>
20553 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20555 2006-02-13 Javier Miranda <miranda@adacore.com>
20557 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20558 handles default-initialized components to keep separate the management
20559 of this feature but also avoid the unrequired resolution and
20560 expansion of components that do not have partially initialized
20562 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20563 (Check_Bounds): Likewise.
20564 (Check_Length): Likewise.
20566 2006-02-13 Javier Miranda <miranda@adacore.com>
20567 Ed Schonberg <schonberg@adacore.com>
20569 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20570 abstract interface type call analyze_and_resolve to expand the type
20571 conversion into the corresponding displacement of the
20572 reference to the base of the object.
20573 (Eval_Attribute, case Width): For systems where IEEE extended precision
20574 is supported, the maximum exponent occupies 4 decimal digits.
20575 (Accessibility_Message): Add '\' in 2-line warning message.
20576 (Resolve_Attribute): Likewise.
20577 (case Attribute_Access): Significantly revise checks
20578 for illegal access-to-subprogram Access attributes to properly enforce
20579 the rules of 3.10.2(32/2).
20580 Diagnose use of current instance with an illegal attribute.
20582 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20584 (Enclosing_Generic_Unit): New function to return a node's innermost
20585 enclosing generic declaration node.
20586 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20587 (Type_Access_Level): The accessibility level of anonymous acccess types
20588 associated with discriminants is that of the current instance of the
20589 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20590 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20591 (Kill_Current_Values_For_Entity): New function
20592 (Enter_Name): Change formal type to Entity_Id
20594 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20595 Ed Schonberg <schonberg@adacore.com>
20596 Gary Dismukes <dismukes@adacore.com>
20598 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20599 Analyze_Compilation_Unit.
20600 Detect and warn on redundant with clauses detected in a package spec
20601 and/or body when -gnatwr is used.

20605 with_clause so that cross-reference information or warning messages on
20606 unused packages can be properly generated
20607 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20608 has Error_Posted set. Prevent infinite loops in illegal programs.
20609 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20610 to the point of the error test requiring the current unit to be private.
20611 This ensures that private with clauses are not exempted from the basic
20612 checking for being a descendant of the same library unit parent as a
20613 withed private descendant unit.
20614 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20615 handle private with clauses properly, as well as to account for cases
20616 where the withed unit is a public descendant of a private ancestor
20617 (in which case the current unit must be a descendant of the private
20618 ancestor's parent). The spec comments were updated accordingly. Also,
20619 the old error message in this subprogram was replaced with error
20620 messages that mirror the errors tested and reported by
20621 Check_Private_Child_Unit.
20622 Parameter and variable names improved for readability.
20623 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20624 private as the precondition for calling
20625 Check_Private_Limited_Withed_Unit since that subprogram has been
20626 revised to test public units as well as private units.

20633 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20634 that Scope_Stack.First = 1.
20635 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20636 were not always properly handled previously.
20637 (Formal_Entity): Complete rewrite, to handle properly some complex case
20638 with multiple levels of parametrization by formal packages.
20639 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20640 to the corresponding derived type declaration for proper semantics.
20642 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20643 (Check_Component): Enforce restriction on components of
20644 unchecked_unions: a component in a variant cannot contain tasks or
20646 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20648 Add pragma Ada_2005 (synonym for Ada_05)
20649 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20650 were not always properly handled previously.
20651 Document that pragma Propagate_Exceptions has no effect
20652 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20653 (Set_Convention_From_Pragma): Check that if a convention is
20654 specified for a dispatching operation, then it must be
20655 consistent with the existing convention for the operation.
20656 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20657 longer required to specify an vtable-ptr component in the record. For
20658 compatibility reasons we leave the support for the previous definition.
20659 (Analyze_Pragma, case No_Return): Allow multiple arguments
20661 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20662 non-overrideen inherited operation with a controlling result as
20663 illegal only its implicit declaration comes from the derived type
20664 declaration of its result's type.
20665 (Check_Possible_Deferred_Completion): Relocate the object definition
20666 node of the subtype indication of a deferred constant completion rather
20667 than directly analyzing it. The analysis of the generated subtype will
20668 correctly decorate the GNAT tree.
20669 (Record_Type_Declaration): Check whether this is a declaration for a
20670 limited derived record before analyzing components.
20671 (Analyze_Component_Declaration): Diagnose record types not explicitly
20672 declared limited when a component has a limited type.
20673 (Build_Derived_Record_Type): Code reorganization to check if some of
20674 the inherited subprograms of a tagged type cover interface primitives.
20675 This check was missing in case of a full-type associated with a private
20677 (Constant_Redeclaration): Check that the subtypes of the partial and the
20678 full view of a constrained deferred constant statically match.
20679 (Mentions_T): A reference to the current type in an anonymous access
20680 component declaration must be an entity name.
20681 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20682 class_wide type to refer to full type, not to the incomplete one.
20683 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20684 available. Required to give support to the certified run-time.
20685 (Analyze_Component_Declaration): In case of anonymous access components
20686 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20687 (Process_Discriminants): For an access discriminant, use the
20688 discriminant specification as the associated_node_for_itype, to
20689 simplify accessibility checks.

20694 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20695 abstract interpretations on an operator, remove interpretations that
20696 yield Address or a type derived from it, if one of the operands is an
20698 (Try_Object_Operation.Try_Primitive_Operation,
20699 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20700 location when creating the new reference to a primitive or class-wide
20701 operation as a part of rewriting a subprogram call.
20702 (Try_Primitive_Operations): If context requires a function, collect all
20703 interpretations after the first match, because there may be primitive
20704 operations of the same type with the same profile and different return
20705 types. From code reading.
20706 (Try_Primitive_Operation): Use the node kind to choose the proper
20707 operation when a function and a procedure have the same parameter
20709 (Complete_Object_Operation): If formal is an access parameter and prefix
20710 is an object, rewrite as an Access reference, to match signature of
20711 primitive operation.
20712 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20713 by an expanded name with prefix Standard, when the operands are of an
20714 anonymous access type.
20715 (Remove_Abstract_Operations): If the operation is abstract because it is
20716 inherited by a user-defined type derived from Address, remove it as
20717 well from the set of candidate interpretations of an overloaded node.
20718 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20721 2006-02-13 Bob Duff <duff@adacore.com>
20723 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20724 redundant use clauses.
20725 In particular, if the scope of two use clauses overlaps, but one is not
20726 entirely included in the other, we should not warn. This can happen
20727 with nested packages.
20728 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20729 reported errors. The bug was reported when the compiler was built
20730 with assertions enabled.
20731 (Find_Type): If the node is a 'Class reference and the prefix is a
20732 synchronized type without a corresponding record, return the type
20735 2006-02-13 Javier Miranda <miranda@adacore.com>
20737 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20738 if this is the full-declaration associated with a private declaration
20739 that implement interfaces, then the private type declaration must be
20741 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20742 as aliased. The use of the 'access attribute is not available for such
20743 object (for this purpose the object should be explicitly marked as
20744 aliased, but being an anonymous type this is not possible).
20746 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20747 Robert Dewar <dewar@adacore.com>
20749 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20750 compilation unit is an elaboration scope.
20751 (Add_Task_Proc): Add '\' in 2-line warning message.
20752 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20754 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20755 Javier Miranda <miranda@adacore.com>
20757 * sem_type.adb (Write_Overloads): Improve display of candidate
20759 (Add_One_Interp): Do not add to the list of interpretations aliased
20760 entities corresponding with an abstract interface type that is an
20761 immediate ancestor of a tagged type; otherwise we have a dummy
20762 conflict between this entity and the aliased entity.
20763 (Disambiguate): The predefined equality on universal_access is not
20764 usable if there is a user-defined equality with the proper signature,
20765 declared in the same declarative part as the designated type.
20766 (Find_Unique_Type): The universal_access equality operator defined under
20767 AI-230 does not cover pool specific access types.
20768 (Covers): If one of the types is a generic actual subtype, check whether
20769 it matches the partial view of the other type.
20771 2006-02-13 Thomas Quinot <quinot@adacore.com>
20773 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20774 line. This is necessary to allow In_Extended_Main_Unit to provide
20775 correct results for itypes while writing out expanded source.
20776 (Close_File): No need to update the source_index_table here since it's
20777 now done for each line.
20779 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20780 Robert Dewar <dewar@adacore.com>
20782 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20783 preserve the source unit where the itype is declared, and prevent a
20785 (Note_Implicit_Run_Time_Call): New procedure
20786 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
20789 * sprint.ads: Document use of $ for implicit run time routine call
20791 2006-02-13 Quentin Ochem <ochem@adacore.com>
20793 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
20796 2006-02-13 Bob Duff <duff@adacore.com>
20798 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20799 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20800 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20801 raise Constraint_Error.
20803 * s-vallli.adb (Scan_Long_Long_Integer): Call
20804 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20805 do not scan leading blanks and sign twice.
20806 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20807 raise Constraint_Error.
20809 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20810 Scan_Long_Long_Unsigned): Split out most of the processing from
20811 Scan_Long_Long_Unsigned out into
20812 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20813 This prevents scanning leading blanks and sign twice.
20814 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20817 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20818 out most of the processing from Scan_Unsigned out into
20819 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20820 This prevents scanning leading blanks and sign twice.
20822 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20823 use with Modular'Value attribute.
20824 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
20827 2006-02-13 Robert Dewar <dewar@adacore.com>
20829 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
20831 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>
20833 * tracebak.c (PPC AIX/Darwin): Define FORCE_CALL to 1.
20834 (PPC VxWorks): Likewise.
20835 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
20836 (forced_callee): Make non-inlinable and non-pure.
20837 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

21020 Florian Villoing <villoing@adacore.com>
21022 * a-taster.ads, a-taster.adb: New files.
21024 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21025 link to the version that does nothing. This way the task termination
21026 routine is not executed twice for the environment task when finishing
21027 because of an unhandled exception.
21029 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21030 handler because of an unhandled exception.
21032 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
21033 System.Tasking.Utilities instead of that in System.Tasking.Stages.
21035 * s-finimp.adb (initialization code): Modify the soft link for the
21036 finalization of the global list instead of Adafinal.
21038 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21039 non-tasking version of the soft link for task termination. We do
21040 nothing since if we are using the non-tasking version it
21041 means that the task termination functionality is not used.
21042 (Null_Finalize_Global_List): Add this null version for the procedure
21043 in charge of finalizing the global list for controlled objects.
21044 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21045 instead for handling run-time termination in a more flexible way.
21046 (Adafinal_NT): This new procedure will take care of finalizing the
21047 global list for controlled objects if needed, but no tasking
21050 * s-tarest.adb (Task_Lock): Do not try to lock again the
21051 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21052 some run-time operations.
21053 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21054 until all nested locks have been released.
21055 (Task_Wrapper): Call the fall-back task termination handler. It
21056 applies to all tasks but the environment task.
21057 (Finalize_Global_Tasks): Add the call for the task termination
21058 procedure for the environment task.
21059 (Task_Wrapper): suppress warnings around declaration of
21060 Secondary_Stack_Address.
21062 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21063 moved to the Common_ATCB record.
21064 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21065 Common_ATCB record.
21066 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21067 Common_ATCB record.
21069 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21070 Fall_Back_Handler, and Specific_Handler.
21072 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21073 defined in Ada.Task_Termination, to avoid circular dependencies.
21074 (Termination_Handler): Redefine this type here, alredy defined in
21075 Ada.Task_Termination, for avoiding circular dependencies.
21076 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21077 for storing task termination handlers. In addition,
21078 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21079 Common_ATCB because it is used by both the regular and the restricted
21081 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21082 Common_ATCB because it is used by both the regular and the restricted
21084 (Common_ATCB): Added a dynamic task analyzer field.
21086 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21087 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21088 (Task_Wrapper): Call the task termination handler. It applies to all
21089 tasks but the environment task.
21090 (Finalize_Global_Tasks): Call the task termination procedure for the
21091 environment task. The call to Finalize_Global_List is now performed
21092 using the soft links mechanism.
21093 (Task_Wrapper): added dynamic stack analysis.
21095 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21096 potentially blocking operations has been moved from
21097 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21098 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21099 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21100 this run-time check.
21102 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21103 of task termination procedure.
21104 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21105 link for the task termination procedure.
21107 * bindusg.adb: (Bindusg): Added documentation for -u option.
21109 * bindgen.adb (Get_Main_Ada) Added handling of dynamic stack analysis.

21117 * opt.ads: Added flags used by dynamic stack measurement.
21118 (Max_Line_Length): Remove (not used anymore)
21120 * s-io.ads, s-io.adb (Standard_Error): new subprogram
21121 (Standart_Output): new subprogram
21122 (Set_Output): new subprogram
21123 (Put): now uses the value of Current_Out to know if the output has to be
21124 send to stderr or stdout.
21126 * s-stausa.ads: Complete implementation.
21128 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
21130 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
21131 list of Ada 05 files.
21132 (GNAT Library Units): Add AltiVec files.
21134 * g-allein.ads, g-alleve.adb, g-alleve.ads, g-altcon.adb,
21135 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
21136 g-alvety.ads, g-alvevi.ads: New files providing altivec API.
21138 2005-12-09 Nicolas Setton <setton@adacore.com>
21140 * adaint.c (__gnat_locate_regular_file): Return immediately if
21141 file_name is empty.
21143 2005-12-09 Javier Miranda <miranda@adacore.com>
21144 Hristian Kirtchev <kirtchev@adacore.com>
21146 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21147 to the specification because the frontend generates code that uses this
21149 (Set_Interface_Table): Add missing assertion.
21150 Update documentation describing the run-time structure.
21151 (Displace): New subprogram that displaces the pointer to the object
21152 to reference one of its secondary dispatch tables.
21153 (IW_Membership): Modified to use the new table of interfaces.
21154 (Inherit_TSD): Modified to use the new table of interfaces.
21155 (Register_Interface_Tag): Use the additional formal to fill the
21156 contents of the new table of interfaces.
21157 (Set_Interface_Table): New subprogram that stores in the TSD the
21158 pointer to the table of interfaces.
21159 (Set_Offset_To_Top): Use the additional formal to save copy of
21160 the offset value in the table of interfaces.
21161 Update structure of GNAT Primary and Secondary dispatch table diagram.
21162 Add comment section on GNAT dispatch table prologue.
21163 (Offset_To_Signature): Update the constant value of the Signature field.
21164 (Dispatch_Table): Update comment on hidden fields in the prologue.
21165 (Get_Entry_Index, Get_Prim_Op_Kind, Get_Offset_Index, OSD,
21166 Set_Entry_Index, Set_Offset_Index, Set_Prim_Op_Kind, SSD, TSD): Change
21167 the type of formal parameter T to Tag, introduce additional assertions.
21168 (Get_Num_Prim_Ops, Set_Num_Prim_Ops): Remove an unnecessary type
21170 (Get_Tagged_Kind, Set_Tagged_Kind): New bodies.
21172 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21173 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21174 record component containing the tag of the secondary dispatch table we
21175 have to use the Offset_To_Top run-time function to get this information;
21176 otherwise if the pointer to the base of the object has been displace
21177 we get a wrong value if we use the 'position attribute.
21179 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21180 all the calls to Expand_Interface_Thunk.
21181 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

21374 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
21375 base type to create anonymous subtype, because entity may be a locally
21376 declared subtype or generic actual.
21377 (Find_Interface): New subprogram that given a tagged type and one of its
21378 component associated with the secondary table of an abstract interface
21379 type, return the entity associated with such abstract interface type.

21382 conversion cannot be handled at compile time. In this case we pass this
21383 information to the expander to generate the appropriate code.

21421 legal within a protected type that implements an interface.
21422 (Collect_Interfaces): Do not add to the list the interfaces that
21423 are implemented by the ancestors.
21424 (Derived_Type_Declaration): If the parent of the full-view is an
21425 interface perform a transformation of the tree to ensure that it has
21426 the same parent than the partial-view. This simplifies the job of the
21427 expander in order to generate the correct object layout, and it is
21428 needed because the list of interfaces of the full-view can be given in
21430 (Process_Full_View): The parent of the full-view does not need to be
21431 a descendant of the parent of the partial view if both parents are
21433 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21434 "limited" the parent must be a limited type.

21448 (Process_Full_View): Improve the check for the "no hidden interface"
21449 rule as defined by AI-396.
21451 2005-12-09 Robert Dewar <dewar@adacore.com>
21453 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
21454 types, not on record subtypes.

21507 * sem_cat.adb (Validate_RCI_Subprogram_Declaration): Revise test for
21508 available user-specified stream attributes on limited parameters to
21509 also test the type directly rather than only its underlying type (for
21510 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21511 attributes are visible at the point of the subprogram declaration.
21512 For Ada 2005, the error message is modified to indicate that the
21513 type's stream attributes must be visible (again, only for -gnat05).

21545 types use the corresponding record type. This was not needed before
21546 the implementation of Ada 2005 synchronized types because
21547 concurrent types were never tagged types in Ada 95.

21793 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for

21822 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
21823 longer sets Elaboration_Checks.

21952 we are not defining the type.
21953 <E_Record_Type>: Likewise.
21954 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
21955 to get advantage of the new maybe_stabilize_reference interface, to

21958 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
21959 type imported through a limited_with clause, use its non-limited view.
21960 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others

21965 before early-returning for certain types when code generation is

21969 that we are not defining.
21970 (elaborate_expression_1): Do not create constants when creating
21971 variables needed by the debug info: the dwarf2 writer considers that
21972 CONST_DECLs is used only to represent enumeration constants, and emits
21974 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
21975 object with an address clause into an indirect reference, drop the

21988 subtype to build an actual type with bounds template.
21989 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
21990 is provided by the front-end, use that subtype to compute the size of
21991 the deallocated object.

21993 check for a potential violation of a No_Elaboration_Code restriction.

21998 maybe_stabilize, for common uses without restriction on lvalues and
21999 without need to check for the success indication.
22000 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22001 pass false instead of 0 as the FORCE argument which is a bool.
22002 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22003 attached to a renaming pointer has been properly stabilized, as no such
22004 object is attached otherwise.
22005 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22006 function uses the "target pointer" return mechanism.
22007 Reinstate conversion of the actual to the type of the formal
22008 parameter before any other specific treatment based on the passing

22019 static output of record constructor if all the components are constant.
22020 (gnat_build_constructor): For a record type, sort the list of field
22021 initializers in increasing bit position order.

22023 from a fat or thin pointer type and a constrained object type.
22024 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22025 types variants, and process special cases of VIEW_CONVERT expressions

22027 CORRESPONDING_VARs associated with CONST_DECls.
22028 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22029 on the right-hand side.

22036 extracting the object if converting to a type variant.
22037 (create_var_decl): When a variable has an initializer requiring code
22038 generation and we are at the top level, check for a potential violation
22039 of a No_Elaboration_Code restriction.
22040 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN

22183 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22184 for task component, in the case of a limited aggregate. The enclosed
22185 object declaration will create it earlier. Otherwise, in the case of a
22186 nested aggregate, the object may appear in the wrong scope.
22187 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
22188 (Gen_Assign): If the component being assigned is an array type and the
22189 expression is itself an aggregate, wrap the assignment in a block to
22190 force finalization actions on the temporary created for each row of the
22192 (Build_Record_Aggr_Code): Significant rewrite insuring that ctrl
22193 structures are initialized after all discriminants are set so that
22194 they can be accessed even when their offset is dynamic.

22222 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
22223 and related): For a prefix that is an explicit dereference of an
22224 access to unconstrained packed array type, annotate the dereference
22225 with an actual subtype so GIGI can make a correct size computation.
22226 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22227 'Unrestricted_Access, if the designated type is an interface we
22228 add a type conversion to force the displacement of the pointer
22229 to the secondary dispatch table.
22230 Use Universal_Real instead of Long_Long_Float when we need a high
22231 precision float type for the generated code (prevents gratuitous
22232 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22233 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22234 'Terminated for task interface class-wide objects. Generate a call to
22235 the predefined dispatching routine used to retrieve the _task_id from
22236 a task corresponding record.

22260 (Expand_N_If_Statement): When killing a dead then-branch in an
22261 if-statement that has elsif_parts, recompute the Current_Value node
22262 for any entity whose value is known from the condition of the first
22264 (Expand_N_Return_Statement): When returning a mutable record, convert
22265 the return value into its actual subtype in order to help the backend
22266 to return the actual size instead of the maximum. This is another
22267 aftermath of not returning mutable records on the sec-stack anymore.
22269 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
22270 handling of error msg for suspicious reverse range iteration.
22271 (Check_Possible_Current_Value_Condition): Move declaration from body to

22292 (Send_Signal): Release the process handle.
22294 2005-11-14 Robert Dewar <dewar@adacore.com>
22296 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we
22297 need a high precision float type for the generated code (prevents
22298 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
22301 * exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we

22316 attribute of the N_Free_Statement.
22317 Generate itype for classwide designated object in both cases of
22318 user-specified storage pool: specific and class-wide, not only in the
22320 Raise CE when trying to set a not null access type object to null.
22321 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
22322 an explicit loop, because freeze nodes make its position variable.

22541 parent scopes of a scope being removed prior to inlining an instance
22543 (Analyze_Package_Instantiation): Do not perform front-end inlining when

22545 unit, to prevent scope stack errors.
22546 (Save_References): If the node is an aggregate that is an actual in a
22547 call, rewrite as a qualified expression to preserve some type
22548 information, to resolve possible ambiguities in the instance.
22549 (Instance_Parent_Unit): New global variable to record the ultimate
22550 parent unit associated with a generic child unit instance (associated

22558 not already set. Replace test of Is_Child_Unit with test of parent's
22559 scope against package Standard. Add comments and a ??? comment.
22560 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
22561 on a child instance parent to test that the parent equals

22578 (Build_Private_Derived_Type): The entity of the created full view of the
22579 derived type does not come from source. If after installing the private

22581 full view to construct the full declaration of the derived type.
22582 (Build_Derived_Record_Type): Relax the condition that controls the
22583 execution of the check that verifies that the partial view and

22592 view is a transitive derivation of the ancestor of the partial view.
22593 (Process_Full_View): Rename local subprogram Find_Interface_In_
22594 Descendant to Find_Ancestor_Interface to leave the code more clear.
22595 Remove wrong code that avoids the generation of an error message
22596 when the immediate ancestor of the partial view is an interface.
22597 In addition some minor reorganization of the code has been done to
22598 leave it more clear.
22599 (Analyze_Type_Declaration): If type has previous incomplete tagged
22600 partial view, inherit properly its primitive operations.
22601 (Collect_Interfaces): Make public, for analysis of formal

22614 be included in the interface list.
22615 (Access_Definition): If the designated type is an interface that may
22616 contain tasks, create Master_Id for it before analyzing the expression
22617 of the declaration, which may be an allocator.

22624 * sem_ch6.adb (Check_Conformance): The null-exclusion feature can be
22625 omitted in case of stream attribute subprograms.
22626 (Check_Inline_Pragma): Handle Inline and Inline_Always pragmas that
22627 appear immediately after a subprogram body, when there is no previous
22628 subprogram declaration.
22629 Change name Is_Package to Is_Package_Or_Generic_Package
22630 (Process_Formals): A non null qualifier on a non null named access
22631 type is not an error, and is a warning only if Redundant_Constructs
22634 2005-11-14 Gary Dismukes <dismukes@adacore.com>
22635 Ed Schonberg <schonberg@adacore.com>
22637 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
22638 nested within Analyze_Package_Specification to install the private
22639 declarations and use clauses within each of the parent units of a
22640 package instance of a generic child package.
22641 (Analyze_Package_Specification): When entering a private part of a
22642 package associated with a generic instance or formal package, the
22643 private declarations of the parent must be installed (by calling new
22644 procedure Install_Parent_Private_Declarations).
22645 Change name Is_Package to Is_Package_Or_Generic_Package
22646 (Preserve_Full_Attributes): For a synchronized type, the corresponding
22647 record is absent in a generic context, which does not indicate a
22650 2005-11-14 Ed Schonberg <schonberg@adacore.com>
22652 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22653 not try to rewrite a renamed stream attribute, because the operations
22654 on the type may not have been generated.
22655 Handle properly a renaming_as_body generated for a stream operation
22656 whose default is abstract because the object type itself is abstract.
22657 (Find_Type): If the type is incomplete and appears as the prefix of a
22658 'Class reference, it is tagged, and its list of primitive operations
22659 must be initialized properly.
22660 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22661 private declaration of a parent unit, prior to compiling the private
22662 part of a child unit, find on the scope stack the proper parent entity
22663 on which to link the use clause.
22664 (Note_Redundant_Use): Emit a warning when a redundant use clause is
22666 (Analyze_Object_Renaming): An attribute reference is not a legal object
22667 if it is not a function call.

22670 Ed Schonberg <schonberg@adacore.com>
22672 * sem_eval.adb: Implement d.f flag
22673 (Subtype_Statically_Match): A generic actual type has unknown
22674 discriminants when the corresponding actual has a similar partial view.

22680 Robert Dewar <dewar@adacore.com>
22681 Thomas Quinot <quinot@adacore.com>
22683 * sem_res.adb (Resolve_Call): Provide a better error message whenever
22684 a procedure call is used as a select statement trigger and is not an
22685 entry renaming or a primitive of a limited interface.
22686 (Valid_Conversion): If the operand has a single interpretation do not
22687 remove address operations.
22688 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22689 statement to inhibit warning.
22690 (Resolve_Unary_Op): Do not produce a warning when
22691 processing an expression of the form -(A mod B)
22692 Use Universal_Real instead of Long_Long_Float when we need a high
22693 precision float type for the generated code (prevents gratuitous
22694 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22695 (Resolve_Concatenation_Arg): Improve error message when argument is an
22696 ambiguous call to a function that returns an array.
22697 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
22698 there is an implicit operator in the given scope if we are within an
22699 instance: legality check has been performed on the generic.
22700 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
22701 after resolving operand, to avoid false warnings on overloaded calls.
22703 2005-11-14 Ed Schonberg <schonberg@adacore.com>
22704 Javier Miranda <miranda@adacore.com>
22707 * sem_type.adb (Covers): In an inlined body, a composite type matches
22708 a private type whose full view is a composite type.
22709 (Interface_Present_In_Ancestor): Protect the frontend against
22710 previously detected errors to ensure that its compilation
22711 with assertions enabled gives the same output that its
22712 compilation without assertions.
22713 (Interface_Present_In_Ancestor): Add support for private types.
22714 Change name In_Actual to In_Generic_Actual (clean up)
22715 (Disambiguate): New predicate In_Actual, to recognize expressions that
22716 appear in the renaming declaration generated for generic actuals, and
22717 which must be resolved in the outer context.

22731 for a parameterless procedure.
22732 (Enter_Name): Recognize renaming declarations created for private
22733 component of a protected type within protected operations, so that
22734 the source name of the component can be used in the debugger.

23383 entity of a primitive wrapper.
23384 (Write_Entity_Flags): Output the name and value of the
23385 Is_Primitive_Wrapper attribute.
23386 (Write_Field27_Name): Output the name and entity of the field Wrapped_
23388 (Underlying_Type): If we have an incomplete entity that comes from

23422 to build an anonymous access type. This allows further cleanup in the
23423 code generated by the expander.
23424 (Expand_Interface_Conversion): If the actual is an access type then
23425 build an internal function to handle the displacement. If the actual
23426 is null this function returns null because no displacement is
23427 required; otherwise performs a type conversion that will be
23428 expanded in the code that returns the value of the displaced actual.
23429 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
23430 conversions that have no effect in the generated code because no
23431 displacement is required. Code cleanup; use local variables to

23441 (Expand_Subtype_From_Expr): Do not build actual subtype if the
23442 expression is limited.
23443 (Find_Interface_Tag): Add code to handle class-wide types and
23444 entities from the limited-view.
23446 * rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
23447 Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,

23477 package can be used for VxWorks 5.x and 6.x
23478 (ATCB_Key, ATCB_Key_Address): Moved to Specific package body to hide
23479 differences between VxWorks 5.x and 6.x

23536 This change also makes gen-soccon self-contained (removing dependencies
23537 upon GCC internal headers).
23539 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
23541 (To_Inet_Addr): Now a procedure instead of a function, more efficient.

23675 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23676 from object notation, the original node is unanalyzed and carries no
23677 semantic information, so that accessiblity checks must be performed on

23691 load comes from a Limited_With_Clause.
23693 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23694 whether a potential circularity is harmless, because it includes units
23695 loaded through a limited_with clause. Extends previous treatment which
23696 did not handle properly arbitrary combinations of limited and
23697 non-limited clauses.

23733 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
23734 position set is provided, we compute one in order to reduce the maximum
23735 length of the keys. This computation first selects a character
23736 position between 1 and the minimum length of the keys in order to
23737 avoid reducing one of the keys to an empty string.
23738 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23739 does not converge. The initialization procedure now comes with a
23740 maximum number of iterations such that when exceeded, an exception is
23741 raised in Compute. The user can initialize this ratio to another value
23743 Reformating and updated headers.
23745 2005-09-01 Javier Miranda <miranda@adacore.com>
23747 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
23748 that given an entity T creates and returns an Itype that duplicates the
23749 contents of T. The returned Itype has the null-exclusion
23750 attribute set to True, and its Etype attribute references T
23751 to keep the association between the two entities.
23752 Update copyright notice
23754 * sem_aggr.adb (Check_Can_Never_Be_Null,
23755 Aggregate_Constraint_Checks, Resolve_Aggregate,
23756 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
23758 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

23767 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
23769 Call Set_Result_Definition instead of Set_Subtype_Mark.
23770 (P_Subprogram_Specification): Add parsing of anonymous access result
23771 plus null exclusions. Call Set_Result_Definition instead of
23774 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23775 (P_Access_Type_Definition): Add parsing for an anonymous access result
23776 subtype, plus parsing for null exclusions. Call Set_Result_Definition
23777 instead of Set_Subtype_Mark.
23779 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23780 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
23781 (Result_Definition): New function for N_Function_Specifications.
23782 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
23783 N_Function_Specification.
23784 (Set_Null_Exclusion_Present): Allow this flag for
23785 N_Function_Specification.
23786 (Set_Result_Definition): New procedure for N_Function_Specifications.
23787 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
23788 and N_Function_Specification.
23790 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
23791 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
23792 Add support for LIMITED NEW for Ada 2005 AI-419
23793 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
23794 syntax for anonymous access results.
23795 Replace Subtype_Mark field by Result_Definition in
23796 N_Function_Specification and N_Access_Definition specs.
23797 Add Null_Exclusion_Present to spec of N_Function_Specification.
23798 (Result_Definition): New function for N_Function_Specification and
23799 N_Access_Function_Definition.
23800 (Set_Result_Definition): New procedure for N_Function_Specification and
23801 N_Access_Function_Definition.
23803 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
23804 Result_Definition for cases of N_Access_Function_Definition and
23805 N_Function_Specification.
23806 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
23808 2005-09-01 Vincent Celier <celier@adacore.com>
23810 * lib-writ.adb: Update Copyright notice
23811 (Write_With_Lines): On platforms where file names are case-insensitive,
23812 record the file names in lower case.
23813 (Write_ALI): For D lines, on platforms where file names are
23814 case-insensitive, record the file names in lower case.
23816 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23817 Emmanuel Briot <briot@adacore.com>
23819 * lib-xref.adb (Output_Overridden_Op): Display information on
23820 overridden operation.

23824 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
23827 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
23828 overriding entity information.
23830 2005-09-01 Vincent Celier <celier@adacore.com>
23832 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
23833 including those that are inherited.
23835 2005-09-01 Robert Dewar <dewar@adacore.com>
23837 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
23839 * par-prag.adb: Implement new pragma Debug_Policy
23841 * sem_prag.adb Implement new pragma Debug_Policy
23842 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23843 Component_Size attribute specification. Give warning for ignored pragma
23846 * snames.h, snames.ads, snames.adb: Introduce entries in
23847 Preset_Names for Name_Disp_Asynchronous_Select,
23848 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23849 Name_Disp_Timed_Select.
23850 New pragma Debug_Policy
23852 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23854 Switch -gnata also sets Debug_Pragmas_Enabled
23856 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23857 handle an explicit -gnata when compiling predefined files.
23859 2005-09-01 Vincent Celier <celier@adacore.com>
23861 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23862 directories of projects that have no Ada sources.
23864 2005-09-01 Robert Dewar <dewar@adacore.com>
23866 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23867 (makes a difference for wide characters)
23869 * widechar.adb, widechar.ads:
23870 Add Wide_Char_Byte_Count feature to count chars vs bytes
23872 2005-09-01 Thomas Quinot <quinot@adacore.com>
23873 Ed Schonberg <schonberg@adacore.com>
23874 Robert Dewar <dewar@adacore.com>
23876 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23877 'Address attribute reference with an overloaded prefix, use the
23878 location of the prefix (not the location of the attribute reference) as
23879 the error location.
23880 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23881 a function renaming thereof, is a valid prefix for 'Size (where it is
23882 intepreted as a function call).
23883 (Statically_Denotes_Entity): New predicate to determine whether the
23884 prefix of an array attribute can be considered static.
23887 (Eval_Attr): Fix failure to evaluate Component_Size for
23888 unconstrained arrays (resulted in wrong value in packed case, since
23889 back end cannot handle this case)
23891 2005-09-01 Robert Dewar <dewar@adacore.com>
23893 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23894 error msgs for most common cases.
23895 Use new errout insertion char < (conditional warning)
23897 2005-09-01 Javier Miranda <miranda@adacore.com>
23898 Ed Schonberg <schonberg@adacore.com>
23900 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23901 become local to the whole package.
23902 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23903 the package was already analyzed the new algorithm "replaces" the
23904 real entities by the shadow ones. This is required to ensure that
23905 the order of these entities in the homonym chains does not change;
23906 otherwise we can have undefined references at linking time because
23907 in case of conflicts the external name of the entities will have
23908 a suffix that depends on the order of the entities in the chain.
23909 (Remove_Limited_With_Clause): Complementary code that completes the
23910 new algorithm and replaces the shadow entities by the real ones.
23911 (Install_Limited_Withed_Unit): When unchaining entities before the
23912 installation of the shadow entities, only regular entities of the
23913 public part must be taken into account. This is required to
23914 keep this routine in synch with the work done by Remove_Limited_
23916 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
23917 even if unit is analyzed, because the analysis of the unit is
23918 idempotent in any case, and the limited view of the unit may have to
23919 be installed for proper visibility.
23920 (Expand_Limited_With_Clause): Even if the unit in the implicit
23921 with_clause has been analyzed already, a limited view of the package
23922 must be built for the current context, if it does not exist yet.
23924 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23925 Javier Miranda <miranda@adacore.com>
23926 Gary Dismukes <dismukes@adacore.com>
23928 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
23929 defining entity for the instance body, make a new defining identifier
23930 rather than copying the entity of the spec, to prevent accidental
23931 sharing of the entity list.
23932 (Check_Private_View): When exchanging views of private types, build the
23933 list of exchanged views as a stack, to ensure that on exit the exchanges
23934 are undone in the proper order.
23935 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
23936 Restore the compilation environment in case of instantiation_error.
23937 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
23938 for an anonymous access result.
23939 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
23940 (Formal_Entity): Handle properly the case of a formal package that
23941 denotes a generic package renaming.
23943 2005-09-01 Thomas Quinot <quinot@adacore.com>
23945 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
23946 clause if the array aggregate is surrounded by parentheses.
23948 2005-09-01 Cyrille Comar <comar@adacore.com>
23949 Gary Dismukes <dismukes@adacore.com>
23950 Ed Schonberg <schonberg@adacore.com>
23951 Javier Miranda <miranda@adacore.com>
23953 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
23955 to check if a type is Constrained in cases related to code generation
23956 (rather than semantic checking) since otherwise we do not generate
23957 similar code for mutable private types depending if their
23958 discriminants are visible or not.
23959 (Check_Abstract_Overriding): Do not complain about failure to override
23960 the primitive operations used in dispatching selects since they will
23961 always be overriden at the freeze point of the type.
23962 (Access_Definition): Separate out handling for resetting the scope
23963 of an anonymous access function result type. Retrieve the scope
23964 of the associated function rather than using Current_Scope, which
23965 does not have a consistent value (depends on whether we're in the
23966 middle of analyzing formal parameters). Add ??? comment about
23967 finding a cleaner way to handle the special cases of scope setting.
23968 (Process_Incomplete_Dependents): A protected operation is never a
23969 dispatching operation (only its wrapper may be).
23970 (Build_Derived_Record_Type): In case of tagged private types that
23971 implement interfaces add derivation of predefined primitive
23973 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
23974 by two parameters that are used in case of derivation from abstract
23975 interface types: No_Predefined_Prims is used to avoid the derivation
23976 of predefined primitives from the interface, and Predefined
23977 Prims_Only is used to complete the derivation predefined primitives
23978 in case of private tagged types implementing interfaces.
23979 Fix typo in comments
23980 (Find_Interface_In_Descendant): Protect the frontend against
23981 wrong code with large circularity chains.
23982 (Is_Private_Overriding): Add support for entities overriding interface
23983 subprograms. The test failed because Entities associated with overriden
23984 interface subprograms are always marked as hidden (and used to build
23985 the secondary dispatch table); in this case the overriden entity is
23986 available through the field abstract_interface_alias (cf. override_
23987 dispatching_operation)
23988 (Access_Definition): Set the scope of the type to Current_Scope for the
23989 case of a function with an anonymous access result type.
23990 (Access_Subprogram_Declaration): Handle creation of the type entity for
23991 an access-to-function type with an anonymous access result.
23992 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
23993 in handling for N_Access_Function_Definition.
23994 (Analyze_Subtype_Declaration): Modify the text of error message.
23995 (Derived_Type_Declaration): Modify the text of error message.
23996 (Process_Subtype): Modify the text of error message plus cleanup
23997 of one redundant error message.
23998 (Analyze_Component_Declaration): Code cleanup.
23999 (Analyze_Object_Declaration): Code cleanup.
24000 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24001 attribute in case of access types. Code cleanup.
24002 (Array_Type_Declaration): Code cleanup.
24003 (Process_Discriminants): Create the new null-excluding itype
24004 if required. Code cleanup.
24005 (Process_Subtype): Create the new null-excluding itype if
24006 required. Code cleanup.
24007 (Build_Derived_Record_Type): Code cleanup to avoid calling
24008 twice the subprogram derive_subprograms in case of private
24009 types that implement interfaces. In this particular case the
24010 subprogram Complete_Subprograms_Derivation already does the
24011 job associated with the second call.
24013 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24014 conversion to the full view when generating an operation for a
24015 discriminant whose type may currently be private.
24017 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24018 Javier Miranda <miranda@adacore.com>
24020 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24021 V (Obj.F), the rewriting does not involve the indexed component, but
24022 only the selected component itself.
24023 Do not apply the transformation if the analyzed node is an actual of a
24024 call to another subprogram.
24025 (Complete_Object_Operation): Retain the entity of the
24026 dispatching operation in the selector of the rewritten node. The
24027 entity will be used in the expansion of dispatching selects.
24028 (Analyze_One_Call): Improve location of the error message associated
24030 (Analyze_Selected_Component): No need to resolve prefix when it is a
24031 function call, resolution is done when parent node is resolved, as
24033 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24034 when attempting to resolve a call transformed from its object notation.
24035 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24036 of the argument list for each interpretation of the operation.
24037 (Try_Object_Operation): The designated type of an access parameter may
24038 be an incomplete type obtained through a limited_with clause, in which
24039 case the primitive operations of the type are retrieved from its full
24041 (Analyze_Call): If this is an indirect call, and the return type of the
24042 access_to_subprogram is incomplete, use its full view if available.
24044 2005-09-01 Javier Miranda <miranda@adacore.com>
24045 Gary Dismukes <dismukes@adacore.com>
24047 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24048 access types the null-exclusion and access-to-constant attributes must
24050 (Analyze_Return_Statement): When the result type is an anonymous access
24051 type, apply a conversion of the return expression to the access type
24052 to ensure that appropriate accessibility checks are performed.
24053 (Analyze_Return_Type): For the case of an anonymous access result type,
24054 generate the Itype and set Is_Local_Anonymous_Access on the type.
24055 Add ??? placeholder for check to disallow returning a limited object
24056 in Ada 2005 unless it's an aggregate or a result of a function call.
24057 Change calls from Subtype_Mark to Result_Definition.
24058 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24059 Result_Definition in call to Make_Function_Specification.
24060 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24061 Set_Result_Definition.
24062 (Make_Inequality_Operator): Change formal Subtype_Mark to
24063 Result_Definition in call to Make_Function_Specification.
24064 (Process_Formals): Create the new null-excluding itype if required.
24065 (New_Overloaded_Entity): For an entity overriding an interface primitive
24066 check if the entity also covers other abstract subprograms in the same
24067 scope. This is required to handle the general case, that is, overriding
24068 other interface primitives and overriding abstract subprograms inherited
24069 from some abstract ancestor type.
24070 (New_Overloaded_Entity): For an overriding entity that comes from
24071 source, note the operation that it overrides.
24072 (Check_Conformance, Type_Conformant): Addition of one new formal
24073 to skip controlling formals in the analysis. This is used to
24074 handle overloading of abstract interfaces.
24075 (Base_Types_Match): Add missing case for types imported from
24076 limited-with clauses
24077 (New_Overloaded_Entity): Add barrier to protect the use of
24078 the "alias" attribute.
24080 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24082 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24083 verify that the procedure and the entry are mode conformant.
24084 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24085 as a different operator, which is often a cut-and-paste error.
24087 2005-09-01 Javier Miranda <miranda@adacore.com>
24088 Ed Schonberg <schonberg@adacore.com>
24090 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24091 used in controlling parameters exclude null because it is necessary to
24092 read the tag to dispatch, and null has no tag.
24093 (Override_Dispatching_Operation): If the previous operation is inherited
24094 from an interface, it becomes hidden and does not participate in later
24097 2005-09-01 Javier Miranda <miranda@adacore.com>
24098 Ed Schonberg <schonberg@adacore.com>
24099 Gary Dismukes <dismukes@adacore.com>
24101 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24102 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24103 the expander will generate the corresponding run-time check to evaluate
24105 (Resolve_Call): Check for legal type of procedure name or prefix that
24106 appears as a trigger in a triggering alternative.
24107 (Valid_Conversion): If expression is ambiguous and the context involves
24108 an extension of System, remove System.Address interpretations.
24109 (Resolve_Qualified_Expression): Reject the case of a specific-type
24110 qualification applied to a class-wide argument. Enhance comment
24111 to explain checking of Original_Node.
24112 (Resolve_Type_Conversion): The location of the error message was not
24113 general enough to handle the general case and hence it has been removed.
24114 In addition, this patch improves the text of the message.
24115 (Resolve_Type_Conversion): Add missing support for access to interface
24117 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24118 do not expand if the expression is the actual in a call, because proper
24119 expansion will take place when the call itself is expanded.
24120 (Resolve_Allocator): If the context is an unchecked conversion, the
24121 allocator inherits its storage pool, if any, from the target type of
24124 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24125 Javier Miranda <miranda@adacore.com>
24127 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24128 inherited interface operation that has an implementation, use the
24129 implementation to avoid spurious ambiguities.
24130 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24131 use the Corresponding_Record_Typ attribute to look for the interface
24132 because it is set by the expander (and hence it is not always
24133 available). For this reason we traverse the list of interfaces
24134 (available in the parent of the concurrent type).
24135 (Interface_Present_In_Ancestor): Handle entities from the limited view
24137 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24139 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24140 from the list of required components.
24141 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24142 primitive procedure of a limited interface with a controlling first
24144 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24146 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24147 capture if it is generated in the second operand of a short-circuit
24149 Do not capture values for variables with address clauses.
24150 (Is_Object_Reference): Treat a function call as an object reference only
24151 if its type is not Standard_Void_Type.
24153 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24155 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24156 to a variable that is statically known to be constant.

24168 Document that bounds of result of Base_Name match the input index
24170 Add documentation on environment variable syntax for Expand_Path
24172 * gnat_ugn.texi: Update documentation to include mention of -m switches
24173 Document new treatment of wide characters in max line length
24175 Remove -gnatL/-gnatZ switches, no longer used.
24176 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24179 * gnat_rm.texi: Add doc for two argument form of pragma
24180 Float_Representation.
24181 Add documentation for pragma No_Strict_Aliasing
24182 Add note that explicit component clause overrides pragma Pack.
24183 Add documentation of pragma Debug_Policy

24939 longer protected objects. They have been replaced by lower-level
24940 suspension objects made up by a mutex and a condition variable (or
24941 their equivalent given a particular OS) plus some internal data to
24942 reflect the state of the suspension object.
24943 (Initialize, Finalize): Add this initialization procedure for
24944 Suspension_Object, which is a controlled type.
24945 (Finalize): Add the finalization procedure for Suspension_Object,
24946 which is a controlled type.
24948 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
24949 Ada.Synchronous_Task_Control because there is no longer a need for a

24951 has been moved to System.Task_Primitives.Operations.
24953 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
24955 (InitializeCriticalSection, EnterCriticalSection,

25407 are to be inlined by the front-end. When the body comes from an
25408 instantiation, a reference to Unchecked_Conversion will be an
25409 Expanded_Name, even though the body has not been analyzed yet.

25430 object or component (that is, when Is_Local_Anonymous_Access is true).
25431 Prevent the special checks for conversions of access discriminants in
25432 the case where the discriminant belongs to a nonlimited type, since

25434 way as a normal component of an anonymous access type.
25435 (Resolve_Allocator): When an allocator's designated type is a class-wide
25436 type, check that the accessibility level of type given in the
25437 allocator's expression or subtype indication is not statically deeper

25449 (Resolve_Actuals): Enable full error reporting on view conversions
25450 between unrelated by_reference array types.
25451 The rule for view conversions of arrays with aliased components is
25452 weakened in Ada 2005.
25453 Call to obsolescent subprogram is now considered to be a violation of
25454 pragma Restrictions (No_Obsolescent_Features).
25455 (Check_Direct_Boolean_Operator): If the boolean operation has been
25456 constant-folded, there is nothing to check.
25457 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25458 check on possible violation of restriction No_Direct_Boolean_Operators
25459 until after expansion of operands, to prevent spurious errors when

25494 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
25495 both bound checks, rather than a conjunction.
25496 (Insert_Valid_Check): If the expression is an actual that is an indexed
25497 component of a bit-packed array, force expansion of the packed element
25498 reference, because it is specifically inhibited elsewhere.

25511 may be deallocated by Normalize_Arguments.
25512 (Collect_Arguments): Eliminate empty arguments
25514 * gnatcmd.adb (All_Projects): New Boolean flag, initialized to False,
25515 and set to True when -U is used for GNAT PRETTY or GNAT METRIC.

26464 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26465 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26466 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26467 analyzed if expansion is disabled (which could otherwise cause spurious
26468 error messages if expansion has been disabled due to previous
26469 (unrelated) errors).
26471 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26472 is disabled, the entity denoted by the argument is the access type
26473 itself, not an underlying record type, so there is no need to go back
26474 to the Corresponding_Remote_Type.
26476 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26477 Robert Dewar <dewar@adacore.com>
26479 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
26480 expand a call to an instance of
26481 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the

26484 denotes a type in the class.
26485 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26486 of Name_Generic_Dispatching_Constructor.
26488 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

26504 generic formal subprogram association for an abstract formal subprogram.
26505 Check that the attribute is a primitive stream attribute (and not
26506 a class-wide stream attribute) and then rewrite the attribute name
26507 as the name of the appropriate compiler-generated stream primitive.

26519 itype whose parent is controlled and not yet frozen, do not create a
26520 freeze node for the itype if expansion is disabled.
26522 2005-03-29 Vincent Celier <celier@adacore.com>
26524 * make.adb (Gnatmake): Don't fail if the main project file is declared
26525 as having no Ada sources. Do not display message "no sources to
26526 compile" in quiet output.
26528 2005-03-29 Doug Rupp <rupp@adacore.com>
26530 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26546 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26547 rather than proceed ahead using a junk attribute name.
26549 2005-03-29 Vincent Celier <celier@adacore.com>
26551 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26553 * prj-part.adb (Parse_Single_Project): Set the location of a project
26554 on its defining identifier, rather than on the reserved word "project".
26556 * prj-proc.adb (Expression): Adapt to the fact that default of external
26557 references may be string expressions, not always literal strings.
26558 (Recursive_Process): Set Display_Name equal to Name
26559 when Location is No_Location, that is when there is no actual file.
26560 Get the Display_Name of the project from the source, when it is not a
26562 (Process): Use the Display_Name in error messages
26564 * prj-strt.adb (External_Reference): Allow default to be string
26565 expressions, not only literal strings.
26567 2005-03-29 Vincent Celier <celier@adacore.com>

26574 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
26575 forbid conversion of a local access-to-subprogram type to a remote one.
26577 * sem_util.adb (Wrong_Type): For a record type that is the expanded
26578 equivalent type for a remote access-to-subprogram type, go back to the
26579 original RAS entity when displaying an error message, so the casing is
26580 the original source casing.

26584 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
26587 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26589 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26590 subtype if code is being pre-analyzed, to prevent un-expanded
26591 references to protected formals, among others.
26592 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26593 interpretation that can be a call, include the result of the call as a
26594 possible interpretation of the dereference.
26596 * sem_ch5.adb (Process_Bounds): Determine type of range by
26597 pre-analyzing a copy of the original range, and then analyze the range
26598 with the expected type.
26600 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26601 with an overloaded prefix where not all interpretations yield an
26602 access to subprogram, do not rewrite node as a call.
26603 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26604 the node as a call once the context identifies the interpretation of
26605 the prefix whose call yields the context type.
26606 (Valid_Conversion): For the case of a conversion between
26607 local access-to-subprogram types, check subtype conformance using
26608 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26609 detailed error message.

26613 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26614 indicator, indicate that the formal can never be null.
26615 (Process_Formals): If a formal has a non_null indicator, insert the
26616 resulting subtype immediately before the enclosing subprogram decl,
26617 and not at the beginning of the corresponding declarative part, to
26618 prevent access before elaboration (Ada2005).

26727 to install the visible declarations of the enclosing scope of a
26728 record_type_with_private to establish the proper visibility before
26729 freezing the entity and related subprograms.

26741 explanatory error message (including the name of the missing attribute).
26742 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
26743 subprogram determines whether a default implementation exists for a
26744 given stream attribute.
26745 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
26746 Determine whether to generate a default implementation for each stream
26747 attribute separately, as this depends on the specific attribute.
26749 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
26750 limited extension where a stream attribute is missing for a limited
26751 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

27317 (P_Protected): Modified to handle the list of interfaces in a
27318 protected type declaration.
27320 2005-03-15 Doug Rupp <rupp@adacore.com>
27321 Vincent Celier <celier@adacore.com>
27323 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27324 (Gen_Output_File_C): Likewise.
27325 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
27327 2005-03-15 Thomas Quinot <quinot@adacore.com>
27329 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27330 is an N_Raise_Constraint_Error node, create a new copy of it without
27331 going through a call to Duplicate_Subexpr.
27333 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
27334 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27335 Nicolas Setton <setton@adacore.com>
27336 Ed Schonberg <schonberg@adacore.com>
27342 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27343 representation clause that prescribes a size not equal to the rounded
27344 size of their types.
27345 (gnat_to_gnu_entity, case E_Component): Always look at
27346 Original_Record_Component if Present and not the entity.
27347 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27348 of tagged extension types by not making field for components that are
27350 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27351 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27352 expression to the type of the object when the object is constant.
27353 Reverse defer_debug_incomplete_list before traversing it, so that trees
27354 are processed in the order at which they were added to the list. This
27355 order is important when using the stabs debug format.
27356 If we are deferring the output of debug information, also defer this
27357 output for a function return type.
27358 When adding fields to a record, prevent emitting debug information
27359 for incomplete records, emit the information only when the record is
27361 (components_to_record): New parameter defer_debug.
27362 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27363 (gnat_to_gnu_field_decl): New function.
27364 (substitution_list, annotate_rep): Call it.
27365 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27366 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27367 No longer update discriminants to not be a COMPONENT_REF.
27368 (copy_alias_set): Strip padding from input type; also handle
27369 unconstrained arrays properly.
27371 * gigi.h (write_record_type_debug_info): New function.
27372 Convert to use ANSI-style prototypes. Remove unused
27373 declarations for emit_stack_check, elab_all_gnat and
27374 set_second_error_entity.
27375 (gnat_to_gnu_field_decl): New decl.
27377 * utils.c (write_record_type_debug_info): New function.

27380 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27381 (update_pointer_to): Fix pasto.
27382 (convert) <UNION_TYPE>: Accept slight type variations when
27383 converting to an unchecked union type.
27385 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27386 replace the N_Freeze_Entity with a null statement.
27388 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27389 within a constrained subcomponent of an enclosing record, place the
27390 freeze nodes in the scope stack entry for the enclosing record.
27391 (Undelay_Type): New Subprogram.
27392 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27393 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27394 within records; allow them to have freeze nodes if their base types
27397 * exp_util.adb (Remove_Side_Effects): Properly test for
27398 Expansion_Delayed and handle case when it's inside an
27399 N_Qualified_Expression.
27401 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27402 Comes_From_Generic, to recognize accurately that the parent type in a
27403 derived type declaration can be traced back to a formal type, because
27404 it is one or is derived from one, or because its completion is derived
27406 (Constrain_Component_Type): If component comes from source and has no
27407 explicit constraint, no need to constrain in in a subtype of the
27409 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27410 Minor change to propagate Is_Ada_2005 flag
27412 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27413 Expansion_Delayed is False.
27414 (assoc_to_constructor): Ignore fields that have a
27415 Corresponding_Discriminant.
27416 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27417 function returns "by target", dereference the target pointer using the
27418 type of the actual return value.
27419 <all>: Be prepared for a null gnu_result.
27420 (processed_inline_subprograms): Check flag_really_no_inline
27421 instead of flag_no_inline.
27422 (set_second_error_entity): Remove unused function.

27427 2005-03-15 Robert Dewar <dewar@adacore.com>
27428 Ed Schonberg <schonberg@adacore.com>
27429 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27431 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27432 Must_Be_Byte_Aligned for cases where we do not need to use a
27433 System.Pack_nn unit.
27435 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27437 Needed now that we do some processing for IN parameters as well. This
27438 may well fix some unrelated errors.
27439 (Expand_Call): Handle case of unaligned objects (in particular those
27440 that come from packed arrays).
27441 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27442 renamed entity is an inherited operation, re-expand the call using the
27443 original operation, which is the one to call.
27444 Detect attempt to inline parameterless recursive subprogram.
27445 (Represented_As_Scalar): Fix to work properly with private types
27446 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27447 accurate estimate. Yields True in far fewer cases than before,
27448 improving the quality of code that depends on this test.
27450 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27451 over both visible and private declarations to remove them from tree,
27452 and mark subprograms declared in package as eliminated, to prevent
27453 spurious use in subsequent compilation of generic units in the context.
27455 * exp_util.ads: Minor cleanup in variable names
27457 * sem_eval.ads, sem_eval.adb: Minor reformatting
27458 (Compile_Time_Known_Bounds): New function
27460 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27462 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27463 determining whether an unchecked conversion is needed for the argument
27464 of an initialization call.
27466 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27468 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27469 that appears in the instantiation rather than the internal subtype
27470 generated in the wrapper package, to avoid anomalies in gigi when the
27471 target is derived from a private type whose full view is an access type.
27473 2005-03-15 Robert Dewar <dewar@adacore.com>
27475 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27477 Add documentation to replace the use of this flag
27478 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27481 2005-03-15 Thomas Quinot <quinot@adacore.com>
27483 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27484 here from exp_attr so it can be shared between exp_attr and exp_dist.
27485 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27486 all TSS names, not a subset thereof, and the previous name introduced
27487 an unnecessarily confusion that a distinction might exist between
27488 "OK" TSS names and some "not OK" TSS names.
27490 2005-03-15 Doug Rupp <rupp@adacore.com>
27492 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27495 2005-03-15 Pascal Obry <obry@adacore.com>
27496 Eric Botcazou <ebotcazou@adacore.com>
27500 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27501 when IN_RTS. This is to work around a bootstrap path problem.
27503 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27504 table and pass it to __gnat_install_SEH_handler().
27505 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27507 * lang.opt: Fix specification of -fRTS=.
27509 2005-03-15 Doug Rupp <rupp@adacore.com>
27510 Bernard Banner <banner@adacore.com>
27511 Vincent Celier <celier@adacore.com>
27512 Arnaud Charlet <charlet@adacore.com>
27515 This change works fine when gnatlib is built from the gcc directory,
27516 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27517 is not passed to ada/Makefile.in, so more work is needed by a
27518 Makefile/configure expert.
27520 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27521 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27522 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27524 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27525 Run ranlib on libgccprefix.a
27526 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27527 (ADA_INCLUDE_SRCS): Split Ada packages.
27529 2005-03-15 Robert Dewar <dewar@adacore.com>
27531 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27533 * impunit.adb: Add GNAT.UTF_32
27535 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27537 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27538 now uses GNAT.UTF_32).
27540 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27541 capabilities for categorizing characters using Unicode categories
27543 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27545 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27546 instantiation that has been rewritten as a package body, retrieve spec
27547 to generate proper name for implicit_with_clause.
27548 (Install_Parents): Recognize a parent that is an instantiation but has
27549 been rewritten as a package declaration during analysis.
27551 2005-03-15 Javier Miranda <miranda@adacore.com>
27552 Ed Schonberg <schonberg@adacore.com>
27554 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27555 parameter reported some error we immediately return. This improves the
27556 behaviour of the frontend in case of errors.
27557 (Install_Parent, Remove_Parent): Introduce new flag
27558 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27559 ancestor of a generic child unit, when the child is being instantiated.
27560 (Inline_Instance_Body): If we are compiling the private
27561 part or the body of a child unit, restore the proper visibility of the
27562 parents after compiling the instance body.
27564 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27565 Javier Miranda <miranda@adacore.com>
27568 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27569 of a private type, in which case it is underlying_type that denotes
27570 the proper task. Also modified to use the new entity attribute
27571 that is directly available in the task type and task subtype entities
27572 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27573 arrays when other dimensions than the first are constrained by
27574 discriminants of an enclosing record.
27575 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27576 a combination of indexed and selected components, find ultimate entity
27577 and generate the appropriate reference for it, to suppress spurious
27579 (Note_Possible_Modification): If an entity name has no entity, return.
27580 (Is_Variable): A function call never denotes a variable.
27581 (Requires_Transient_Scope): For record types, recurse only on
27582 components, not on internal subtypes that may have been generated for
27583 constrained components.
27585 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27587 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27588 Eliminated as candidates for resolution. Both efficient, and avoids
27589 anomalies with operators declared in deleted code.
27590 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27591 expansion is disabled (as when compiling a generic) to prevent spurious
27592 warnings on prefixes of selected components.
27594 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27596 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27597 attached to a list before checking whether it appears in the private
27598 declarations of the current package.
27599 (Make_Inequality_Operator): Insert declaration in proper declarative
27600 list rather than just setting the Parent field, so that
27601 Is_Private_Declaration can handle it properly.
27603 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27605 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27606 a renaming a body, check that the renamed subprogram in not intrinsic.
27607 (Find_Direct_Name): If several use_visible entities hide
27608 each other, and the context is a predefined file compiled through
27609 rtsfind, keep only the entity that comes from a predefined file.
27611 2005-03-15 Geert Bosch <bosch@adacore.com>
27613 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27614 long float padding to also cover AMD64 and IA64.
27616 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27618 * s-imgwch.adb: Add with and use of Interfaces.
27619 (Img_Wide_Character): Change type of Val to Unsigned_16.
27620 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27622 2005-03-15 Matthew Gingell <gingell@adacore.com>
27624 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
27626 2005-03-15 Robert Dewar <dewar@adacore.com>
27628 * usage.adb: Add missing lines for -gnat95 and -gnat05 switches
27630 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
27632 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95

27660 2005-03-15 Vincent Celier <celier@adacore.com>
27662 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

27667 Cyrille Comar <comar@adacore.com>
27668 Sergey Rybin <rybin@adacore.com>
27670 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
27671 too specific and long-winded to be appropriate for the GNAT User's
27673 Warn about use of GCC switches not documented in the GNAT User's Guide,
27674 as these may cause generated code to not conform to Ada semantics.
27675 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
27676 Add documentation for -gnat95 and -gnat05 switches
27677 Remove paragraph documenting obsolete way to refer to third party
27679 Add a few references to Ada_05 that were missing.
27680 Update documentation on -gnatZ/-gnatL.

28096 the formal subprogram.
28097 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28098 which is an unclean use of that field, we set the new field

28122 as the tagged type for the cases of abstract formal subprograms and
28123 renamings of those. Clean up spec comments.
28124 (Check_Dispatching_Context): Add error message to indicate "abstract
28125 procedure", covering the case of a call to a formal abstract procedure
28126 that has statically tagged operands.
28127 (Check_Dispatching_Call): Check for the case of an actual given by
28128 a tag-indeterminate function call whose type is an ancestor of the
28129 containing call's associated tagged type. This situation can occur
28130 for inherited primitives with function defaults. In this case we
28131 use the tagged type's tag directly as the controlling argument for

28236 component of an array of arrays in an assignment context, and the
28237 aggregate has component associations that require sliding on

28275 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
28276 (GNATBIND_OBJS): Idem.
28278 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28279 routine takes a new parameter (a pointer to the exception registration

28283 Update copyright notice.
28285 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28286 record and initialize it by calling __gnat_install_SEH_handler.

28324 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28325 with expansion disabled. The actual subtype is needed among other
28326 places when the selected component appears in the context of a loop
28327 bound, and denotes a packed array.
28328 (Operator_Check): Always use the first subtype in the
28329 error message, to avoid the appearance of internal base types.
28330 (Transform_Object_Operation): Copy each actual in full
28331 to the parameter associations of the constructed call, rather than
28332 using the shallow copy mechanism of New_Copy_List. This ensures that
28333 the chaining of named associations is done properly.
28334 (Complete_Object_Operation): Rewrite node, rather than
28335 replacing it, so that we can trace back to the original selected
28338 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28339 and calls that use object notation, if the called function is not
28340 declared in a withed unit, place the elaboration constraint on the
28341 unit in the context that makes the function accessible.
28342 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28343 imposes an elaboration constraint between two packages.
28345 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28347 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28348 views of a private type after handling its private dependents, to
28349 maintain proper stack discipline between entry and exit from the

28372 * xr_tabls.ads: Add ??? comment for missing overall comment
28374 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28375 we now use by default.
28377 * xsnames.adb: Adjust end of file test to look for five space followed
28378 by '#' instead of six spaces. The format of xsnames.adb was modified
28379 in the last update.

28384 * clean.adb: Minor reformatting.
28386 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28387 gnatname.adb: Minor reformatting

28390 * csets.adb: Eliminate obsolete comment
28392 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28395 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28397 2005-02-09 Sergey Rybin <rybin@adacore.com>
28399 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28400 the difference between compact and incompact layout and add the record
28401 representation clause to the example illustrating different layouts.
28402 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28403 component clauses").
28405 2005-02-09 Florian Villoing <villoing@adacore.com>
28407 * gnat_ugn.texi: Fix typos.
28408 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

28707 2005-01-03 Olivier Hainque <hainque@adacore.com>
28709 * decl.c (compatible_signatures_p): New function. The intended purpose
28710 is to check if two function signatures for a call-site and a callee are
28711 compatible enough for the call to be valid. The underlying purpose is
28712 to check if a call to a mapped builtin is using the right interface.
28713 The current code actually does not check antyhing - this a placeholder

29253 used to record an implicit dereference as a read operation on its
29254 prefix when operating under -gnatc. Necessary to avoid spurious
29255 'variable assigned but never read' warnings in that mode.
29256 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29257 is a non-overloaded implicit dereference, call the above subprogram to
29258 ensure proper recording of references.
29260 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29262 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

29276 2004-12-07 Thomas Quinot <quinot@adacore.com>
29278 * g-socket.ads (Get_Host_By_Address, Get_Host_By_Name): Clarify
29279 documentation of the behaviour of these functions when passed an IP
29280 address that has no record in the system hosts database and no reverse
29283 * cstand.adb, a-tags.ads: Fix typos in comment.
29285 2004-12-07 Robert Dewar <dewar@adacore.com>

29300 2004-12-07 Vincent Celier <celier@adacore.com>
29301 Sergey Rybin <rybin@adacore.com>
29303 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
29304 Files" with the new tool and package names.
29305 Reformatting to suppress most of the warnings for line too long
29306 Document the new section "Project Search Path:" in the output of
29308 Add gnatmetric section
29310 2004-12-07 Vincent Celier <celier@adacore.com>
29312 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29313 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29314 and -eit to -ept. Added qualifier
29315 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29317 2004-11-27 Andreas Schwab <schwab@suse.de>
29319 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29321 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29323 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29324 internal implementation unit GNAT.Sockets.Thin,
29325 as their usage for sockets is non-portable (using the read and write
29326 functions from the system runtime library is fine on UNIX but won't
29327 work under Windows).
29329 * mingw32.h: Update copyright notice.
29331 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29333 * ada-tree.h: Minor reformatting of previous change to avoid lines
29334 longer than 79 characters.
29336 2004-11-25 Olivier Hainque <hainque@adacore.com>
29338 * tb-gcc.c: GCC infrastructure based implementation of

29355 Style_Check_Order_Subprograms.
29357 2004-11-18 Arnaud Charlet <charlet@adacore.com>
29359 * adaint.h, adaint.c
29360 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
29362 Add also a cast to kill another warning.
29363 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
29364 parameter with the priority class of the parent process instead of
29365 always using the NORMAL_PRIORITY_CLASS.
29366 (__gnat_dup): New function.
29367 (__gnat_dup2): New function.
29368 (__gnat_is_symbolic_link): Enable the effective body of this
29369 function when __APPLE__ is defined.
29371 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
29374 2004-11-18 Olivier Hainque <hainque@adacore.com>
29376 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
29377 address of which may be used to represent "others" and "all others"
29378 choices in exception tables, instead of the current harcoded
29379 (void *)0 and (void *)1.
29380 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29382 * gigi.h (others_decl, all_others_decl): New decls representing the
29383 new Others_Value and All_Others_Value objects.
29384 (struct attrib): Rename "arg" component as "args", since GCC expects a
29385 list of arguments in there.
29387 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29388 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29391 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29392 others_decl and all_others_decl instead of hardcoded dummy addresses
29393 to represent "others" and "all others" choices, which is cleaner and
29394 more flexible with respect to the possible eh pointer encoding policies.
29396 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29397 (process_attributes): Account for the naming change of the "args"
29398 attribute list entry component.
29400 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29401 cumulating attributes for different entities into a single list.
29402 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29403 attributes for the current entity and propagate first subtype
29404 attributes to other subtypes.
29405 <E_Procedure>: Attribute arguments are attr->args and not
29406 attr->arg any more.
29407 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29408 argument provided, as this is what GCC expects. Use NULL_TREE instead
29411 2004-11-18 Robert Dewar <dewar@adacore.com>
29413 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
29414 Minor reformatting througout (including new function specs)
29415 Add ??? comments asking for clarification.
29417 2004-11-18 Thomas Quinot <quinot@adacore.com>
29419 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
29420 incomplete duplicate implementation of this subprogram from butil.
29422 2004-11-18 Thomas Quinot <quinot@adacore.com>
29424 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
29425 procedures factors the common processing for building an RPC receiver
29426 for an RCI package or an RACW type.
29427 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
29428 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
29429 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
29431 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
29433 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
29435 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
29436 distribution subprogram identifiers that are either subprogram numbers

29439 string distribution identifiers assigned to a given subprogram.
29440 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29441 (Add_RAS_Dereference_TSS): Add comments.
29442 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29443 is not referenced yet because it will be used by the PolyORB DSA
29445 (Insert_Partition_Check): Remove fossile code.
29446 (First_RCI_Subprogram_Id): Document this constant.
29447 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29449 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29450 replaced with calls to Get_Library_Unit_Name_String. Previously there
29451 were several instances of the same code in different locations in the
29452 compiler; this checkin completes the replacement of all of these
29453 instances with calls to a common subprogram.
29454 Minor reformatting.
29456 * sem_dist.adb: Remove comment noting that RPC receiver generation
29457 should be disabled for RACWs that implement RASs.
29458 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
29460 * sem_util.ads, sem_util.adb (Has_Stream): New function

29462 qualified name of a library unit into the name buffer.
29463 (Note_Possible_Modification): Generate a reference only
29464 if the context comes from source.
29466 * snames.ads (PCS_Names): New subtype corresponding to names of
29467 supported implementations of the Partition Communication Subsystem
29468 (PCS) (i.e. the runtime library support modules for the distributed

29478 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
29480 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
29482 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29483 (Expand_Pragma_Psect_Object): New procedure
29484 These procedures contain the revised and cleaned up processing for
29485 these two pragmas. This processing was formerly in Sem_Prag, but
29486 is more appropriately moved here. The cleanup involves making sure
29487 that the pragmas are properly attached to the tree, and that no
29488 nodes are improperly shared.
29490 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29491 pragmas to Exp_Prag, which is more appropriate.
29492 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29493 check for duplicates Remove use of Is_Psected flag, no longer needed.
29494 Use new Make_String_Literal function with string.
29496 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29497 that are functions return universal values, that have to be converted
29498 to the context type.
29499 Use new Make_String_Literal function with string.
29500 (Get_Stream_Convert_Pragma): New function, replaces the use of
29501 Get_Rep_Pragma, which had to be kludged to work in this case.
29503 * freeze.adb: Use new Has_Rep_Pragma function
29505 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29506 function with string.
29507 Use new Has_Rep_Pragma function.
29509 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29512 2004-11-18 Robert Dewar <dewar@adacore.com>
29514 * errout.ads, errout.adb: (First_Sloc): New function
29516 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29517 check (-gnatyx) instead of being included as a redundant construct
29520 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29521 Style_Check_Order_Subprograms.
29523 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29524 stylesw.adb: Add Style_Check_Xtra_Parens
29526 * usage.adb: Add line for -gnatyx (check extra parens)
29528 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29530 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29531 Robert Dewar <dewar@adacore.com>
29533 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29534 discriminant of a constrained subtype, analyze the copy of the
29535 corresponding constraint, because in some cases it may be only
29536 partially analyzed.
29537 Removes long-lived ??? comments.
29539 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29540 handled controlled or secondary-stack expressions within the
29541 iteration_scheme of a loop.
29543 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29544 bounds that may contain functions calls, to prevent memory leaks when
29545 the bound contains a call to a function that uses the secondary stack.
29546 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29547 generate temporaries for loop bounds that might contain function calls
29548 that require secondary stack and/or finalization actions.
29550 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29551 selected component and the selector is overloadable (not just a
29552 function) treat as function call, Analyze_Call will disambiguate if
29554 (Analyze_Selected_Component): Do not generate an actual subtype for the
29555 selected component if expansion is disabled. The actual subtype is only
29556 needed for constraint checks.
29557 (Analyze_Allocator): If restriction No_Streams is set, then do
29558 not permit objects to be declared of a stream type, or of a
29559 composite type containing a stream.
29561 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29562 No_Streams no longer prohibits with'ing this package.
29564 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29565 discriminants, but the parent base has unknown discriminants, there is
29566 no discriminant constraint to inherit. Such a discrepancy can arise
29567 when the actual for a formal type with unknown discriminants is a
29568 similar private type whose full view has discriminants.
29569 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29570 do not permit objects to be declared of a stream type, or of a
29571 composite type containing a stream.
29573 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29575 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29576 protected operations.
29578 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29579 generated name, it complicates decoding in gdb and hinders debugging
29580 of protected operations.
29581 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29582 flag for the protected entry barrier function.
29583 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29584 flag for the protected entry function.
29586 2004-11-18 Nicolas Setton <setton@adacore.com>
29588 * expect.c: Define __unix__ when __APPLE__ is defined.
29590 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29591 Darwin-specific section.
29593 * lang-specs.h: Change the placement of the %1 marker.
29594 Works around the fact that gcc adds -fPIC by default under Darwin.
29596 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29598 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29599 type of the object with the packed array type, set the Analyzed flag
29600 on the object if it is an entity or simple indexed component, to avoid
29601 spurious type errors.
29603 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29605 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29606 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29607 separate line from the version message.
29609 2004-11-18 Ed Falis <falis@adacore.com>
29611 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29613 (init_float): Eliminate initialization of floating point status for
29614 AE653. The instructions have no effect for vThreads.
29616 2004-11-18 Vincent Celier <celier@adacore.com>
29618 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29619 gnatbind is invoked with -shared.
29621 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29623 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29624 for Detect_Blocking which is redundant with the check done within the
29625 procedure Protected_Single_Entry_Call.
29626 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29627 Detect_Blocking which is redundant with the check done within the
29628 procedure Protected_Single_Entry_Call.
29630 2004-11-18 Vincent Celier <celier@adacore.com>
29632 * makegpr.adb (Compile): Put the compiling switches (in package
29633 Compiler and on the command line) immediately after "-c", instead of
29634 at the end of the command line invocation of the compiler, when
29635 compiling a non-Ada file.
29636 (Build_Global_Archive): When there is no need to rebuild the archive,
29637 set Global_Archive_Exists, so that the archive is passed to the linker
29640 2004-11-18 Robert Dewar <dewar@adacore.com>
29641 Sergey Rybin <rybin@adacore.com>
29644 Remove extra paren check from list of checks for redundant constructs
29645 Add documentation of new -gnatyx style check (check extra parens)
29646 Remove paragraph about gnatelim debug options.
29648 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29649 objects rather than forbidding dependencies on the package Ada.Streams.
29651 * sinfo.ads: Add ??? note that we should document pragmas passed to
29654 * g-expect.ads: Fix a few typos in the comments.
29656 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29658 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29661 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29663 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29665 2004-11-07 Andreas Schwab <schwab@suse.de>
29667 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29669 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29672 * Makefile.in (darwin): Set soext to .dylib.
29674 2004-10-26 Vincent Celier <celier@gnat.com>
29675 Thomas Quinot <quinot@act-europe.fr>
29677 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29678 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29679 there is no use of GNAT.Sockets.Constants.
29680 Remove remaining pragma Import for C_Write
29681 Remove C_Read and C_Write from internal implementation unit
29682 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29683 the read and write functions from the system runtime library is fine
29684 on UNIX but won't work under Windows).
29686 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29687 (Check_Selector): Use C_Recv instead of C_Read.
29688 Selectors are the GNAT.Sockets abstraction to perform a select()
29689 call on a set of descriptors. To allow abortion of an ongoing
29690 select operation, some data is written to a dedicated socket that
29691 is always monitored.
29692 Under Windows, the write and read library functions cannot operate
29693 on sockets, so we need to use send and recv instead, which is portable
29694 across all supported platforms.
29696 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29697 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29698 (using the read and write functions from the system runtime library is
29699 fine on UNIX but won't work under Windows).
29701 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29703 * mlib-tgt-darwin.adb: New file.
29705 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29706 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29707 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29708 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29711 * Makefile.in: Add support for building shared libraries under Darwin.
29712 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29713 the low level EH init subprogram to be called from __gnat_initialize.
29715 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29716 indicates which options to pass to the archive indexer.
29718 * mlib-utl.adb: Add support for calling ranlib with additional
29719 options. This is needed for instance under Mac OS X.
29720 (Ranlib_Options): New global variable, used to store the potential
29721 options to pass to ranlib.
29722 (Ar): Use Ranlib_Options when spawning ranlib.
29723 (Initialize): Set the value of ranlib option.
29725 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29727 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29728 instead of 8K, to reflect the real potential needs for stack-checking
29731 2004-10-26 Pascal Obry <obry@gnat.com>
29733 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29735 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29736 Windows only the initial thread stack size can be set so it is good to
29737 start we a low stack size.
29738 The OS will adjust the size as needed.
29740 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29741 Nicolas Setton <setton@act-europe.fr>
29743 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29744 "__unix__" instead of "unix".
29745 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29746 sections were just mistakenly ignored. The former is
29747 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29748 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29749 of hpux. This prevents an unwanted definition of the symbol
29750 convert_addresses in adaint.o.
29752 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29754 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29755 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29757 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29759 * a-filico.ads, a-filico.adb: fix incorrect header.
29761 2004-10-26 Javier Miranda <miranda@gnat.com>
29763 * a-ststio.ads: Fix typo in identifier

29767 * sem_ch4.adb: Minor reformatting.
29769 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29771 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29772 enabled, check the result of unary and binary operations when the
29773 expression is the right-hand side of an assignment.
29775 2004-10-26 Vincent Celier <celier@gnat.com>
29777 * clean.adb (Delete): Do not output warnings when in quiet output and
29778 not in verbose mode.
29779 (Force_Deletions): New Boolean flag, defaulted to False
29780 (Delete): Only delete a file if it is writable, and when
29781 Force_Deletions is True.
29782 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29783 (Usage): Line for new switch -f
29784 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29787 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29789 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29790 JM type only if its size matches that of the wrapper. When a size is
29791 prescribed and the field is not aliased, remove the wrapper of a JM
29792 type only if the size is not greater than that of the packed array.
29793 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29796 2004-10-26 Geert Bosch <bosch@gnat.com>
29798 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29799 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29800 (Pred): Implement in terms of Succ.
29802 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29804 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29805 unchecked conversion is safe for in-place use if the expression of the
29806 conversion is safe.
29807 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29808 be expandable in place even if the aggregate does not come from source.
29809 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29810 designated object of an allocator in place, rather than building it
29811 first on the stack. The previous scheme forces a full copy of the array,
29812 and may be altogether unsusable if the size of the array is too large
29813 for stack allocation.
29815 2004-10-26 Robert Dewar <dewar@gnat.com>
29817 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29818 compares if the component is atomic.
29820 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29821 array assignment if the component type is atomic.
29823 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29824 Eric Botcazou <ebotcazou@act-europe.fr>
29826 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29827 is aliased and is a by_reference type, do not pass by copy.
29828 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29829 detect whether the call is in the right side of an assignment or
29830 the expression of an object declaration. Recurse on component
29831 association within aggregates.
29832 Call it in the condition that determines whether the temporary is
29833 necessary for correct stack-checking.
29835 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29837 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29838 RACW_Type, used in the PolyORB version.
29839 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29840 version and the GARLIC version.
29842 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29843 Rename RCI_Info to RCI_Locator for better consistency between the
29844 GARLIC and PolyORB versions of the distributed systems annex.
29845 (DSA_Implementation_Name): This enumeration lists the possible
29846 implementations of the Partition Communication Subsystem for the
29847 Distributed Systems Annex (DSA). The three available implementations
29848 are the dummy stub implementation (No_DSA), and two versions based on
29849 two different distribution runtime libraries: GARLIC and PolyORB. Both
29850 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29852 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29855 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29856 between the GARLIC and PolyORB versions of the distributed systems
29858 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29860 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29862 * gnat1drv.adb: Suppress calling the back end when
29863 Frontend_Layout_On_Target is true.
29865 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29867 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29868 Set_Read_Only): New subprograms.
29869 These new routines allow the user to set or unset the Owner execute
29870 and Owner write permission flags on a file.
29872 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29873 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29875 2004-10-26 Matthew Gingell <gingell@gnat.com>
29877 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29879 2004-10-26 Pascal Obry <obry@gnat.com>
29881 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29882 memory before the faulting page we properly test the process read
29883 access for this address using appropriate Win32 routine.
29884 (HPUX sections): guard with "__hpux__" instead of "hpux".
29886 2004-10-26 Robert Dewar <dewar@gnat.com>
29888 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29889 entry parameter if pragma Unreferenced set, since we do not properly
29890 handle the case of multiple parameters.
29892 2004-10-26 Vincent Celier <celier@gnat.com>
29894 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29895 (Ada_Objects_Path.Add): For a library project, add to the object path
29896 the library directory only if there is no object directory or if the
29897 library directory contains ALI files.
29898 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29900 2004-10-26 Vincent Celier <celier@gnat.com>
29902 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29903 extension of library projects.
29905 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29906 path defaults to ".:<prefix>/lib/gnat".
29907 (Parse): For an extending all project, allow direct import of a project
29908 that is virtually extended.
29910 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29911 the specified name is directly imported, return its ID. Otherwise, if
29912 an extension of this project is imported, return the ID of the
29915 2004-10-26 Robert Dewar <dewar@gnat.com>
29917 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
29918 (Sub3): New procedure, used by Scaled_Divide
29919 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
29920 correct more than one instance of failure to propagate carries
29922 (Double_Divide): Handle overflow case of largest negative number
29923 divided by minus one.
29925 * s-arit64.ads (Double_Divide): Document that overflow can occur in
29926 the case of a quotient value out of range.
29929 2004-10-26 Robert Dewar <dewar@gnat.com>
29931 * s-bitops.adb (Bit_Eq): Remove redundant check.
29933 * s-bitops.ads: Minor comment updates
29934 Change some occurrences of Address to System.Address
29936 * s-carsi8.ads: Fix minor cut-and-paste error in comments
29938 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29940 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
29941 accessibility check to prefix that is a protected operation.
29943 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29945 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
29946 empty, post message on stub.
29948 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29949 Javier Miranda <miranda@gnat.com>
29951 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
29952 current instance appears within a unit that is directly in the context
29954 Used to determine whether the body of the instance should be analyzed
29955 immediately after its spec, to make its subprogram bodies available
29956 for front-end inlining.
29957 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
29958 constraint is not allowed on the component type (AARM 12.5.3(3))
29960 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29962 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
29963 'Storage_Pool): enhance, document & limit detection of non-sharable
29966 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
29968 * s-pooglo.ads: Add more documentation now that this pool is properly
29971 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29973 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
29974 or protected type with discriminants, do not constrain the
29975 corresponding record type if the subtype declaration has no
29976 discriminant constraints. This can be the case in source code, or in
29977 the subtype declaration created to rename an actual type within an
29980 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29982 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
29983 different kind of stub (possibly wrong name for file), do not check
29985 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
29986 includes call to some function that returns an unconstrained type, do
29989 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29991 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
29992 appear in the code for the main unit. Dependencies among units in the
29993 context of the main unit are established when those other units are
29994 compiled. Otherwise spurious elaboration constraints can generate
29995 incorrect elaboration circularities.
29997 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29998 Ed Schonberg <schonberg@gnat.com>
30000 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30001 subprogram is called with a parameter that is not an object name. This
30002 situation arises for some cases of illegal code, which is diagnosed
30003 later, and in this case it is wrong to call Is_Aliased, as that might
30004 cause a compiler crash.
30005 (Explain_Limited_Type): Refine previous fix to include
30006 inherited components of derived types, to provide complete information.
30008 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30009 is the prival for a protected object.
30010 It is necessary to mark this entity as a variable, in addition to
30011 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30012 modified to avoid checking the Aliased flag on entities that are not
30013 objects. (Checking that flag for non-objects is erroneous and could
30014 lead to a compiler crash).
30016 2004-10-26 Robert Dewar <dewar@gnat.com>
30018 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30019 X_Frac = 0.5, then we know that the number X must be positive.
30020 (Succ): Remove the same redundant test, and also fix the primary test
30021 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30023 (Decompose): Add fuller comments to spec
30025 2004-10-26 Pascal Obry <obry@gnat.com>
30027 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30028 validity (process must have read access). Set to 0 in all other cases.
30029 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30030 violation on Win32.
30031 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30032 segmentation violation.
30034 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30036 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30037 whose type is a constructed subtype of an aliased object with an
30038 unconstrained nominal subtype, convert the actual to the constructed
30039 subtype before taking its address.
30041 2004-10-26 Vincent Celier <celier@gnat.com>
30043 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30044 (Is_Path_Name_Case_Sensitive): New function
30046 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30047 (Base_Name, Simple_Name, Current_Directory, Compose,
30048 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30051 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30052 Vasiliy Fofanov <fofanov@act-europe.fr>
30053 Vincent Celier <celier@gnat.com>
30055 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30056 "memory management issues" section and document some of the useful
30057 memory pools provided as part of the GNAT library.
30058 Remove "virtual" from declaration of A::method2 in
30059 the simple example of Ada/C++ mixed system.
30060 Library Projects may be virtually extended: their virtual extensions
30061 are not Library Projects.
30062 Added section on extending project hierarchies.
30064 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30066 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30068 (__gnat_portable_spawn): Remove const.
30070 * mingw32.h (MAXPATHLEN): Check for previous definition.
30072 2004-10-17 Matthias Klose <doko@debian.org>
30074 * gnatvsn.ads: Set gnat library version to 4.0.
30076 2004-10-05 Vincent Celier <celier@gnat.com>
30078 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30080 2004-10-04 Laurent Guerby <laurent@guerby.net>
30083 * Makefile.in: Define and use RANLIB_FLAGS.
30085 2004-10-04 Pascal Obry <obry@gnat.com>
30087 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30088 other x86 platforms).
30090 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30092 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30093 in general and triggers stack alignment adjustment for thread entry
30094 points on targets where this is necessary.
30096 2004-10-04 Bernard Banner <banner@gnat.com>
30099 * Makefile.in: Add section for powerpc linux
30100 Add variant i-vxwork-x86.ads
30102 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30104 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30106 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30107 table registration calls when need be. Ensures no reference to the crt
30108 ctors symbol are issued in the SJLJ case, which avoids possible
30109 undefined symbol errors in the case of modules to be statically linked
30112 2004-10-04 Javier Miranda <miranda@gnat.com>
30114 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30115 in-line the code corresponding to subprogram Analyze_Actuals. In
30116 addition, analyze the actuals only in case of subprogram call.
30118 2004-10-04 Ed Falis <falis@gnat.com>
30120 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30122 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30124 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30125 in the documentation.
30127 2004-10-04 Robert Dewar <dewar@gnat.com>
30129 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30131 (Analyze_Block_Statement): Add circuitry to detect following dead code
30132 (Check_Unreachable_Code): Handle case of block exit
30134 2004-10-04 Robert Dewar <dewar@gnat.com>
30136 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30137 (XMatchD): Avoid warning for Logic_Error call
30139 2004-10-04 Robert Dewar <dewar@gnat.com>
30141 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30142 consider expressions buried within a procedure actual to be an actual.
30143 This caused some blowups with uses of packed slices within a procedure
30146 2004-10-04 Robert Dewar <dewar@gnat.com>
30148 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30149 longer need to be initialized to zero.
30150 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30151 initialized to zero.
30153 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30154 considered valid, even if the representation is modular. That's correct
30155 now that we no longer initialize packed modular arrays to zero.
30157 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30158 suffixes. These are now documented as the only cases in which the
30159 debugger ignores outer records.
30160 Previously, the spec allowed arbitrary suffixes for this purpose.
30161 Change name of LJM to JM for packed array pad records
30162 Create separate section on packed array handling, and add a whole new
30163 set of comments to this section describing the situation with packed
30164 modular types and justification requirements depending on endianness.
30166 2004-10-04 Robert Dewar <dewar@gnat.com>
30168 * a-except.adb: Add a comment for last change

30177 * sem_util.ads: Minor comment update
30179 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30181 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30182 Inline_Always when in Configurable_Run_Time mode.
30184 * sem_prag.adb (Process_Convention): If entity is an inherited
30185 subprogram, apply convention to parent subprogram if in same scope.
30186 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30187 when in Configurable_Run_Time mode.
30189 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30191 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30192 class_wide type after component list has been inherited.
30194 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30196 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30197 Denotes_Previous_Actual, to handle properly the case of a private
30198 actual that is also the component type of a subsequent array actual.
30199 The visibility status of the first actual is not affected when the
30200 second is installed.
30201 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30202 make fully recursive the treatment of formals of packages declared
30204 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30205 the above on exit from an instantiation.
30206 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30207 current instantiation which is now complete.
30208 (Analyze_Package_Instantiation): No instantiated body is needed if the
30209 main unit is generic. Efficient, and avoid anomalies when a instance
30210 appears in a package accessed through rtsfind.
30212 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30214 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30215 do not generate a declaration for a temporary if the call is part of a
30216 library-level instantiation.
30218 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30220 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30221 searching for a limited component to flag.
30223 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30224 expansion of Input, to account for the fact that the implicit call
30225 generated by the attribute reference must freeze the user-defined
30226 stream subprogram. This is only relevant to 'Input, because it can
30227 appear in an object declaration, prior to the body of the subprogram.
30229 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30230 expansion can proceed and further errors uncovered.
30231 (Minor clean up): Fix cases of using | instead of \ for continuation
30234 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30236 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30238 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30239 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30240 Use gcc_assert and gcc_unreachable.
30242 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30243 specified alignment before validating size.
30244 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30245 stripped-down declaration for the type of the inner field when making
30248 * utils.c (finish_record_type): Do not compute the size in units
30249 incrementally. Instead compute it once for the rep clause case.
30250 Use gcc_assert and gcc_unreachable.
30252 2004-10-04 Vincent Celier <celier@gnat.com>
30254 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30256 (Is_Valid_Path_Name): Take '/' as a directory separator.
30258 2004-10-04 Vincent Celier <celier@gnat.com>
30260 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30261 (Extended_Project) only if Extended_Project is defined, to avoid
30263 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30265 (Parse_Single_Project): Ditto.
30267 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30268 Add_To_Project_Path for virtual projects.
30270 2004-10-04 Vincent Celier <celier@gnat.com>

30275 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30276 parameter Options_2.
30278 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30279 Build_Dynamic_Library with an empty Options_2.
30281 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no

30285 directory separator, if any.
30286 (Gprmake): Do not allow mains on the command line for library projects.
30287 Do not attempt to link when the project is a library project.
30288 (Library_Opts): New table to store Library_Options.
30289 (Build_Library): If Library_Options is specified, pass these options
30290 when building a shared library.
30292 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30294 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30295 the end of this procedure now that the unlock operation was inserted
30298 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30300 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30301 corresponding to the Preallocated_Stacks flags in System.
30302 (Get_Target_Parameters): Including the processing for

30314 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30315 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30316 used to signal whether the compiler creates the required stacks and
30317 descriptors for the different tasks (when True) or it is done by the
30318 underlying operating system at run time (when False).
30319 It is initially set to False in all targets.
30321 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30322 if it is supported by the target.
30323 (Make_Task_Create_Call): Pass the stack address if it has been
30324 previously created. Otherwise pass a Null_Address.
30326 * snames.adb: Add _stack.
30328 * snames.ads: Add Name_uStack. Required to allow the expander to
30329 statically allocated task stacks.
30331 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30332 Stack_Address argument.
30333 Check that its value is equal to Null_Address because this target does
30334 not support the static stack allocation.

30343 * exp_dist.adb: Split declaration of asynchronous flag out of
30344 Add_RACW_Read_Attribute.
30345 Minor reformatting for better alignment with PolyORB version.
30346 Store the entity for the asynchronous flag of an RACW, rather than the
30347 expression, in the asynchronous flags table. This will allow this flag
30348 to be used in other subprograms beside Add_RACW_Read_Attribute.
30350 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30352 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30357 sockets constant MSG_NOSIGNAL (Linux-specific).
30358 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30359 all Send operations.
30360 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30361 from trigerring SIGPIPE.
30362 Rename components to avoid clash with Ada 2005 possible reserved
30364 (Check_Selector): When the select system call returns with an error
30365 condition, propagate Socket_Error to the caller.

30377 Change "pragma inline" to "pragma Inline" in information and error
30379 Minor reformatting.
30381 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30382 right way of doing things after all.
30383 (Freeze_Entity): For object, set Is_Public for imported entities
30384 unless there is an address clause present.
30386 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30388 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30389 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30390 ensures proper handling of types with rep clauses, which might have
30391 their TYPE_SIZE set already.
30393 2004-09-21 Robert Dewar <dewar@gnat.com>
30395 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30396 packed array types in both little- and big-endian cases. This change
30397 ensures that we no longer count on the unused bits being initialized
30398 for such types (and in particular ensures that equality testing will
30399 only read the relevant bits).
30400 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30401 These changes mean that we no longer need to initialize small packed
30403 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30404 optimization to an LJM field as to its parent field.
30406 * ada-tree.h, trans.c, utils.c, utils2.c:
30407 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30409 2004-09-20 Jan Hubicka <jh@suse.cz>
30411 * utils.c (gnat_finalize): Remove.
30412 (end_subprog_body): Directly call cgraph_finalize_function;
30413 do not lower the nested functions.
30415 2004-09-20 Robert Dewar <dewar@gnat.com>
30418 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30419 if an address clause is present, since that means that the Import

30427 Zack Weinberg <zack@codesourcery.com>
30429 * ada-tree.def: Use tree_code_class enumeration constants
30430 instead of code letters.

30448 an existing directory.
30449 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30450 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30451 Convert the result to File_Size.
30453 * prj.ads: (Project_Error): New exception
30455 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30456 Prj.Com, not from Osint.
30457 (Attrs, Package_Attributes): Tables moved to private part of spec
30458 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30460 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30461 Prj.Project_Error after call to Fail.
30462 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30463 Fail. Check that package name is not already in use.
30465 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30466 used by tools, not only by the project manager, and to indicate that
30467 exception Prj.Prj_Error may be raised in case of problem.
30468 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30470 (Attrs, Package_Attributes): Table instantiations moved from the body to
30471 the private part to be accessible from Prj.Attr.PM body.
30473 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30474 from new package Prj.Attr.PM.
30475 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30478 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
30480 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check

30526 pragmas recognized by GNAT.
30528 * gnat_rm.texi: Document pragma Detect_Blocking.
30530 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
30531 raise Program_Error if called from a protected operation.
30533 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30534 the protected action nesting level.
30535 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30536 protected action nesting level.
30537 (Unlock): When pragma Detect_Blocking is active decrease the protected
30538 action nesting level.
30540 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30541 Protected_Action_Nesting.
30543 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30544 Common_ATCB record. It contains the dynamic level of protected action
30545 nesting for each task. It is needed for checking whether potentially
30546 blocking operations are called from protected operations.
30547 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30548 Detect_Blocking is active or not in the partition.
30550 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
30551 raise Program_Error if called from a protected operation.

30578 active, raise Program_Error if called from a protected operation.
30579 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
30580 protected action nesting level.
30582 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30583 insertion of the statement raising Program_Error. The run time
30584 contains the required machinery for handling that.
30586 * sem_util.ads: Change comment associated to procedure
30587 Check_Potentially_Blocking_Operation.
30588 This procedure does not insert a call for raising the exception because
30589 that is currently done by the run time.
30591 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30593 * init.c: Add the global variable __gl_detect_blocking that indicates
30594 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30595 making the pragma available at run time.
30596 (__gnat_set_globals): Pass and update the detect_blocking parameter.
30598 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
30599 pragma Detect_Blocking is active.
30601 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30603 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30604 DB is found in the ali file. Any unit compiled with pragma
30605 Detect_Blocking active forces its effect in the whole partition.
30607 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30608 Detect_Blocking is active and delay is called from a protected
30611 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30612 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30613 Detect_Blocking is active (0 otherwise).
30614 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30615 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
30618 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
30620 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30621 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30624 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30625 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30626 Update API in placeholder implemetation of s-parint to reflect changes
30627 in distribution runtime library.
30629 * sem_ch3.adb (Expand_Derived_Record): Rename to
30630 Expand_Record_Extension.
30632 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30633 primitive operations of potentially distributed object types that have
30634 non-controlling anonymous access formals.
30636 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30638 New implementation of expansion for remote access-to-subprogram types,
30639 based on the RACW infrastructure.
30640 This version of sem_dist is compatible with PolyORB/DSA as well as
30643 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30644 Asynchrronous that applies to a remote access-to-subprogram type, mark
30645 the underlying RACW type as asynchronous.
30647 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30648 __gnat_using_gnu_linker to 1.
30650 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30651 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
30652 GNAT.Perfect_Hash_Generators, and remove the empty

30657 * exp_ch3.adb (Expand_Derived_Record): Rename to
30658 Expand_Record_Extension.
30659 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30660 a component declaration must remain attached at that point in the
30661 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30662 It is therefore necessary to take a copy of the expression when building
30663 the corresponding assignment statement in the init proc.
30664 As a side effect, in the case of a derived record type, we now see the
30665 original expression, without any rewriting that could have occurred
30666 during expansion of the ancestor type's init proc, and we do not need
30667 to go back to Original_Node.
30669 * exp_ch3.ads (Expand_Derived_Record): Rename to
30670 Expand_Record_Extension.
30672 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
30673 Returns the RACW type used to implement a remote access-to-subprogram
30675 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
30676 New subprograms. Used to create a proxy tagged object for a remote
30677 subprogram. The proxy object is used as the designated object
30678 for RAS values on the same partition (unless All_Calls_Remote applies).
30679 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30680 System.Partition_Interface.Get_Unique_Remote_Pointer.
30681 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30682 Renamed from Add_RAS_*_Attribute.
30683 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
30685 New implementation of expansion for remote access-to-subprogram types,
30686 based on the RACW infrastructure.
30688 * exp_dist.ads (Copy_Specification): Update comment to note that this
30689 function can copy the specification from either a subprogram
30690 specification or an access-to-subprogram type definition.
30692 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30694 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30695 in an instance, between an explicit subprogram an one inherited from a
30696 type derived from an actual.
30698 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30699 add a polling call if the subprogram is to be inlined by the back-end,
30700 to avoid repeated calls with multiple inlinings.
30702 * checks.adb (Apply_Alignment_Check): If the expression in the address
30703 clause is a call whose name is not a static entity (e.g. a dispatching
30704 call), treat as dynamic.
30706 2004-09-09 Robert Dewar <dewar@gnat.com>
30708 * g-trasym.ads: Minor reformatting
30710 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

30716 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
30719 2004-09-09 Pascal Obry <obry@gnat.com>
30721 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30722 enable map file generation. Add the right option to generate the map
30723 file if Map_File is set to True.
30725 * gnatdll.adb (Gen_Map_File): New variable.
30726 (Syntax): Add info about new -m (Map_File) option.
30727 (Parse_Command_Line): Add support for -m option.
30728 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

30749 * opt.ads: Add Ada_Version_Runtime constant used to decide which
30750 version of the language is used to compile the run time.
30752 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
30754 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
30755 of variable length temporaries for function return now that the
30756 back-end and gigi support it.
30758 2004-09-01 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30760 * misc.c (gnat_print_type): Use TYPE_RM_SIZE_NUM.

30980 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
30981 discriminants that rename those of the parent, recover names of

31013 returning C.int, to avoid using a derived boolean type.
31015 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

31044 ignore overflows on low and high bounds of an index to also account for
31045 differences in signedness between sizetype and gnu_index_subtype.

34963 complete assignment subtree which is now unnecessary, as the expansion
34964 of inlined call has been improved to preserve a consistent assignment

34966 after checks have been applied, or else unnecessary checks will

35148 the null-excluding type to force the corresponding run-time check.
35150 * exp_ch6.adb (Expand_Call): Do not generate the run-time check in
35151 case of access types unless they have the null-excluding attribute.

35160 part has been scanned-out and it was present
35162 * par-ch3.adb, par-ch4.adb, par-ch6.adb: Give support to AI-231
35164 * sem_aggr.adb: (Check_Can_Never_Be_Null): New subprogram
35165 (Aggregate_Constraint_Checks): Generate conversion to the null-excluding
35166 type to force the corresponding run-time check
35167 (Resolve_Aggregate): Propagate the null-excluding attribute to the array
35169 (Resolve_Array_Aggregate): Carry out some static checks
35170 (Resolve_Record_Aggregate.Get_Value): Carry out some static check
35172 * sem_ch3.adb (Access_Definition): In Ada 0Y the Can_Never_Be_Null
35173 attribute must be set only if specified by means of the null-excluding
35174 part. In addition, we must also propagate the access-constant attribute
35176 (Access_Subprogram_Declaration, Access_Type_Declaration,
35177 Analyze_Component_Declaration, Analyze_Object_Declaration,
35178 Array_Type_Declaration, Process_Discriminants,

35190 (Set_Actual_Subtypes): Generate null-excluding subtype if the
35191 null-excluding part was present; it is not required to be done here in
35192 case of anonymous access types.
35193 (Set_Formal_Mode): Ada 0Y allows anonymous access to have the null
35196 * sem_res.adb (Resolve_Actuals): Carry out some static check
35197 (Resolve_Null): Allow null in anonymous access
35199 * sinfo.adb: New subprogram Null_Exclusion_Present
35200 All_Present and Constant_Present available on access_definition nodes
35202 * sinfo.ads: New flag Null_Exclusion_Present on subtype_declaration,
35203 object_declaration, derived_type_definition, component_definition,

35223 * sem_ch12.adb: Add comment for previous change
35225 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
35227 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35228 executable name when not initialized. Otherwise, use its current value.
35230 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35231 initialize it to another executable name than the current one. This
35232 allows to configure paths for an executable name (gnatmake) different
35233 from the current one (gnatdist).
35235 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35237 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35238 current unit cannot be inlined if it appears in the body of a withed
35239 unit, to avoid order of elaboration problems in gigi.
35241 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35242 information for protected (wrapper) operation as well, to simplify gdb
35245 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35246 protected body, indicate that the entity for the generated spec comes
35247 from source, to ensure that references are properly generated for it.
35248 (Build_Body_To_Inline): Do not inline a function that returns a
35251 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
35252 apply convention to homonyms that are declared explicitly.
35254 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
35255 that renames an equality operator and the operands are overloaded,
35256 resolve them with the declared formal types, before rewriting as an
35259 2004-03-29 GNAT Script <nobody@gnat.com>
35261 * Make-lang.in: Makefile automatically updated
35263 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
35265 * memtrack.adb: Log realloc calls, which are treated as free followed
35268 2004-03-25 Vincent Celier <celier@gnat.com>
35270 * prj-makr.adb (Process_Directories): Detect when a file contains
35271 several units. Do not include such files in the config pragmas or

35282 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35284 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35285 attribute reference does not denote a subtype, it can be any
35286 expression that has a classwide type, potentially after an implicit
35287 dereference. In particular, the prefix can be a view conversion for
35288 a classwide type (for which Is_Object_Reference holds), but it can
35289 also be a value conversion for an access-to-classwide type. In the
35290 latter case, there is an implicit dereference, and the original node
35291 for the prefix does not verify Is_Object_Reference.
35293 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35294 conversion of a discriminant-dependent component of a mutable object
35297 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35299 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35300 inherited, has convention C, and has unconstrained array parameters,
35301 place the corresponding warning on the derived type declaration rather
35302 than the original subprogram.
35304 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35305 indication on renaming declaration, if formal has a box and actual
35308 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35309 determine whether to generate an implicit or explicit reference to
35310 the renamed entity.
35312 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35313 subprogram renaming comes from a defaulted formal subprogram in an
35316 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35318 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35319 value expressions to ensure that calls within a component definition
35320 will be checked (since those are evaluated during the record type's
35323 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
35325 * s-tpobop.adb: Code clean up:
35326 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

35371 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35372 declaration for a child subprogram body that acts as a spec, indicate
35373 that the entity in the declaration needs debugging information.
35375 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35376 full view if the subtype is created for a constrained record component;
35377 gigi has enough information to construct the record, and there is no
35378 place in the tree for the declaration.
35380 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35381 serial number for the dummy body that is built for analysis, to avoid
35382 inconsistencies in the generation of internal names when compiling
35385 2004-03-22 Thomas Quinot <quinot@act-europe.fr>

35413 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
35414 gnat_ug_wnt.texi: Regenerate.
35416 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
35418 * ada-tree.h: Update copyright notice.
35419 Minor reformatting.
35421 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35423 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35424 as regular exception objects and not as mere integers representing the
35425 condition code. The latter approach required some dynamics to mask off
35426 severity bits, which did not fit well into the GCC table based model.
35427 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35428 exception data objects. We don't it and it would conflict with the other
35429 external symbol we have to generate for such exceptions.
35431 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35432 the special code for VMS exceptions, since these are now represented
35433 as regular exceptions objects.
35435 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35437 * decl.c (debug_no_type_hash): Remove.

35439 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
35441 2004-03-19 Laurent Guerby <laurent@guerby.net>
35443 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35444 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35446 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35448 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35449 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35450 (TYPE_RM_SIZE_INT): Directly use type.values.
35451 (TREE_LOOP_ID): Clean up check.
35452 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35453 TYPE_VALUES, not TYPE_FIELDS.
35454 * trans.c (convert_with_check): Delay access of bounds of basetype
35455 until sure is numeric.

35462 * 5ataprop.adb, 5ftaprop.adb, 5htaprop.adb, 5itaprop.adb, 5staprop.adb,
35463 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
35464 Specific.Set instead of direct call to e.g pthread_setspecific.
35466 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35468 * adaint.c: Update comments.
35470 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35471 GNATLIB_SHARED for FreeBSD.
35473 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35475 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35476 When needed (stack checking) the stack size is retrieved
35477 from the VxWorks kernel.
35479 * Makefile.in: Flag -nostdinc is required when building the run time
35480 for avoiding looking for files in the base compiler.
35481 Add the VxWorks specific version of the package body for
35482 System.Stack_checking.Operations (5zstchop.adb).
35484 * Make-lang.in: Add the object file for
35485 System.Stack_Checking.Operations.
35487 * Makefile.rtl: Add object file for the package
35488 System.Stack_Checking.Operations.
35490 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
35492 * s-stache.ads, s-stache.adb: Move the operations related to stack
35493 checking from this package to package System.Stack_Checking.Operations.
35494 This way, stack checking operations are only linked in the final
35495 executable when using the -fstack-check flag.
35497 2004-03-18 Doug Rupp <rupp@gnat.com>
35499 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
35502 * 5qsystem.ads, 5xcrtl.ads: New files.

35508 * prj-env.adb (Source_Paths, Object_Paths): New tables.
35509 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35510 the procedures Add_To_Path_File.
35511 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35512 making sure that each directory is present only once and, for object
35513 dirs, when a directory already present is added, the duplicate is
35514 removed and the directory is always put as the last in the table.
35515 Write the path files at the end of these accumulations.
35517 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35518 Files_Htable for all sources.
35520 * prj-proc.adb (Process): Remove restrictions between not directly
35521 related extending projects.

35529 parameter Trusted_Mode.
35531 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35533 * scn.adb (Determine_License): Take into account a degenerated case
35534 when the source contains only comments.
35536 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35538 * sem_warn.adb (Check_References): For a warning on a selected
35539 component that does not come from source, locate an uninitialized
35540 component of the record type to produce a more precise error message.
35542 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35544 * 3zsoccon.ads: Fix multicast options.
35546 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35549 2004-03-15 Robert Dewar <dewar@gnat.com>
35551 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
35552 pragma used for a private type.
35554 * lib-xref.adb (Generate_Reference): Do not generate warning if
35555 reference is in a different unit from the pragma Unreferenced.
35557 * 5vtpopde.adb: Minor reformatting
35558 Fix casing of To_Task_ID
35560 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35561 flag if we have an unchecked conversion to an access type in the same
35564 2004-03-15 Geert Bosch <bosch@gnat.com>
35566 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35567 imaginary parts, use Double precision throughout.
35569 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35570 we want to be able to compile run-time with -gnata for testing, but
35571 this may also be instantiated in user code that is compiled with -gnata.
35573 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35575 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35576 codes. Having a separate type for this is useful to enforce consistency
35577 throughout the various run-time units.
35578 (Exception_Data): Use Exception_Code for Import_Code.
35580 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
35581 Natural and Integer in various places.
35582 (Register_VMS_Exception): Use Base_Code_In to compute the exception code
35583 with the severity bits masked off.
35584 (Register_VMS_Exception): Handle the additional exception data pointer
35587 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
35588 component, now reflected by an exported accessor.
35589 (is_handled_by): New routine to compute whether the propagated
35590 occurrence matches some handler choice specification. Extracted out of
35591 get_action_description_for, and expanded to take care of the VMS
35593 (get_action_description_for): Use is_handled_by instead of an explicit
35594 complex condition to decide if the current choice at hand catches the
35595 propagated occurrence.
35597 * raise.h (Exception_Code): New type for C.
35599 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35600 System.Standard_Library.Exception_Code, to allow references from the
35601 pragma import/export expander.
35603 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35604 New accessors to allow easy access to GNAT exception data
35606 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35607 redundant Handled_By_Others component, helper for the personality
35608 routine which will now be able to call the appropriate exception data
35611 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35612 component of Standard_Exception_Type to be the closest possible to
35613 Exception_Code in System.Standard_Library, that we cannot get at this
35614 point. Expand a ??? comment to notify that this type node should
35615 probably be rewritten later on.
35617 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35618 registration call to include a pointer to the exception object in the
35621 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35622 instead of int and explicit bitmasks.
35624 2004-03-15 Vincent Celier <celier@gnat.com>
35626 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35627 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35629 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35630 longer needed now that it is in the spec of
35631 System.Tasking.Task_Attributes.
35633 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35635 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35637 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35639 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35640 taken care of in Scan_Make_Arg.
35641 (Scan_Make_Arg): Add the executable suffix only if the argument
35642 following -o, in canonical case, does not end with the executable
35643 suffix. When in verbose mode and executable file name does not end
35644 with executable suffix, output the executable name, in canonical case.
35646 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35647 to avoid warnings when instantiating Ada.Task_Attributes.
35650 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35651 in the correct order.
35653 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
35654 redirect standard output and error to a file for the invocation of the
35655 compiler, then read the file.

37078 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37079 N_String_Literal node always references an E_String_Literal_Subtype
37080 entity. This may not be true in the future.
37081 (Possible_Bit_Aligned_Component): Move processing of
37082 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37084 * exp_ch6.adb (Expand_Thread_Body): Pick up

37089 (Type_May_Have_Bit_Aligned_Components): New function.

37129 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37130 ineffective elaborate all pragmas on non-visible packages (this
37131 happened when a renamed subprogram was called). Now the elaborate all
37132 always goes on the package containing the renaming rather than the one
37133 containing the renamed subprogram.
37135 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37136 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37161 * make.adb (Gnatmake): Special process for files to compile/check when
37162 -B is specified. Fail when there are only foreign mains in attribute

37195 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37197 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37198 all attributes, including read-only attribute.

37203 library naming scheme.

37237 checked when limited aggregates are implemented.

37240 pure, emit warning.

37353 to __gnat_map_signal, imported from init.c to support
37354 signal -> exception mappings that depend on the vxWorks version.
37357 Created and exported __gnat_map_signal to support signal -> exception
37358 mapping that is dependent on the VxWorks version.

37389 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37391 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37392 bounds of a loop, create a separate block in order to generate proper
37393 cleanup actions to prevent memory leaks.
37395 * sem_res.adb (Resolve_Call): After a call to
37396 Establish_Transient_Scope, the call may be rewritten and relocated, in

37415 2003-12-08 Robert Dewar <dewar@gnat.com>
37417 * 7sintman.adb: Minor reformatting
37419 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37420 standard linker options to get standard libraries linked. We now plan
37421 to provide dummy versions of these libraries to match the appropriate
37422 configurable run-time (e.g. if a library is not needed at all, provide
37423 a dummy empty library).
37425 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37426 options (-L parameters and standard libraries). What we plan to do is
37427 to provide dummy libraries where the libraries are not required.
37429 * gnatbind.adb: Minor comment improvement
37431 2003-12-08 Javier Miranda <miranda@gnat.com>
37433 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

37441 of aggregate with default initialized components.
37442 (Has_Default_Init_Comps): Improve implementation to recursively check
37443 all the present expressions.
37445 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37446 to indicate that the initialization call corresponds to a
37447 default-initialized component of an aggregate.
37448 In case of default initialized aggregate with tasks this parameter is
37449 used to generate a null string (this is just a workaround that must be
37450 improved later). In case of discriminants, this parameter is used to
37451 generate a selected component node that gives access to the discriminant
37454 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37455 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37456 allocated aggregates with default-initialized components.
37458 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37459 the box notation is used in positional aggregates.

37501 Process nodes N_Comment.
37503 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37504 without comments and there are some comments, set the flag
37505 Unkept_Comments to True.
37506 (Scan): If there are comments, set the flag Unkept_Comments to True and
37507 clear the comments.
37508 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
37509 (Next_End_Nodes: New table

37537 Comment_Id and set Token to Tok_Comment when scanning a comment.
37538 (Set_Comment_As_Token): New procedure
37540 * sinput-p.adb: Update Copyright notice
37541 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

37546 * sem_aggr.adb: Add dependence on Exp_Tss package
37547 Correct typo in comment
37548 (Resolve_Aggregate): In case of array aggregates set the estimated
37549 type of the aggregate before calling resolve. This is needed to know
37550 the name of the corresponding IP in case of limited array aggregates.
37551 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37552 in case of default initialized array components.
37554 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

37574 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
37575 they are automatically generated by Make-lang.in and cause nothing but
37576 maintenance troubles.
37578 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
37580 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

37594 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
37595 to ensure that the kernel fills in the interrupted context structure
37596 before calling a signal handler, which is necessary to be able to
37597 unwind past it. Update the copyright notice.
37599 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37601 * a-elchha.ads: New file.
37603 * a-elchha.adb: New default last chance handler. Contents taken from

37686 included in HIE_NONE_TARGET_PAIRS.
37688 2003-12-03 Ed Schonberg <schonberg@gnat.com>
37691 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
37692 is legal in an instance, because legality is cheched in the template.
37695 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
37696 appplied to an unchecked conversion of a formal parameter.
37699 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

37713 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
37714 so that the debugger can reliably access the value of the parameter,
37715 and therefore is able to display the exception name when an exception
37716 breakpoint is reached.

38981 (Freeze_Array_Type): We do not need an initialization routine for types
38982 derived from String or Wide_String. They should be treated the same
38983 as String and Wide_String themselves. This caused problems with the
38984 use of Initialize_Scalars.
38987 (Expand_Assign_Record): Do component-wise assignment of non-byte aligned
38988 composites. This allows use of component clauses that are not byte

39009 2003-10-27 GNAT Script <nobody@gnat.com>
39011 * Make-lang.in: Makefile automatically updated
39013 2003-10-27 Ed Schonberg <schonberg@gnat.com>
39016 (Inline_Instance_Body): Indicate that the save/restore of use_clauses
39017 should not be done in Save/Restore_Scope_Stack, because it is performed
39021 (Save_Scope_Stack, Restore_Scope_Stack): Add parameter to indicate
39022 whether use clauses should be removed/restored.
39025 (Save_Scope_Stack, Restore_Scope_Stack): Add parameter to indicate

39050 Removes a trailing space.
39052 2003-10-24 Jose Ruiz <ruiz@act-europe.fr>
39055 Remove the test against being in No_Run_Time_Mode before generating a
39056 call to Register_Tag. It is redundant with the test against the
39057 availability of the function Register_Tag.
39059 2003-10-24 Vincent Celier <celier@gnat.com>
39061 * g-catiio.adb: (Month_Name): Correct spelling of February

39066 project file and, if there are several mains, each of them is a source
39067 of the same project file.
39068 (Gnatmake): When a foreign language is specified in attribute Languages,
39069 no main is specified on the command line and attribute Mains is not
39070 empty, only build the Ada main. If there is no Ada main, just compile
39071 the Ada sources and their closure.
39072 (Gnatmake): If a main is specified on the command line with directory
39073 information, check that the source exists and, if it does, that the path
39074 is the actual path of a source of a project.

39078 Full_Path is True, return the full path instead of the simple file name.
39079 (Project_Of): New function
39082 (File_Name_Of_Library_Unit_Body): New Boolean parameter Full_Path,
39083 defaulted to False.
39084 (Project_Of): New function

39127 External_Tag attribute definition clauses.
39129 2003-10-23 Ed Schonberg <schonberg@gnat.com>
39132 * exp_dbug.adb (Debug_Renaming_Declaration): For the renaming of a
39133 child unit, generate a fully qualified name to avoid spurious errors
39134 when the context contains renamings of different child units with
39135 the same simple name.
39137 * exp_dbug.ads: Add documentation on name qualification for renamings

41243 2002-01-30 Richard Henderson <rth@redhat.com>
41245 * trans.c (tree_transform) [N_Loop_Statement]: Use
41246 expand_exit_loop_top_cond.

41263 (title page): Remove date.
41264 (general) Add @./@: where approriate, and two spaces after the
41265 full stop at the end of a sentence. Use @samp markup when
41266 referring concrete lexical entities (keywords, attribute names
41267 etc.), and @syntax for ARM grammar elements. Use @r for English

41283 function approach did not work well because of a side effect (the
41284 function call could reallocate the table which was being indexed
41285 using its result). Fixes ada/4851.

41346 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
41347 need to force universal inlining for these cases.
41349 2001-12-19 Arnaud Charlet <charlet@gnat.com>
41351 * s-taprob.adb: Minor clean ups so that this unit can be used in

41380 * trans.c (tree_transform, case of arithmetic operators): If result
41381 type is private, the gnu_type is the base type of the full view,
41382 given that the full view itself may be a subtype.
41384 2001-12-17 Robert Dewar <dewar@gnat.com>
41386 * sem_res.adb: Minor reformatting

41652 2001-12-17 Laurent Pautet <pautet@gnat.com>
41655 Fix comment of Shutdown_Socket and Close_Socket. These functions
41656 should not fail silently because if they are called twice, this
41657 probably means that there is a race condition in the user program.
41658 Anyway, this behaviour is consistent with the rest of this unit.

42999 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43000 instead of simple checksum.
43001 (CRC_Match): new function.
43002 (CRC_Error): new constant.
43004 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43005 a CRC now and not a simple checksum. A CRC uses lower-case hex
43006 letters, fixes ambiguity in parsing.
43008 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43009 is what this variable will store.
43011 * bcheck.adb: Change reference to chechsum in comments by CRC.
43012 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43013 rename All_Checksum_Match to All_CRC_Match. Change due to API
43014 renaming since now GNAT does not use a simple checksum but a
43015 CRC using GNAT.CRC32.
43017 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43018 now and not anymore a simple checksum.
43020 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many

43055 Update comments for the CRC.
43057 * types.adb (Hex): Use lowercase for the letter part.
43059 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43060 for a word. This is currently used only for CRC. In previous version,
43061 the checksum was using a representation with all letter being
43062 upper-case. With the new implementation (using CRC) we do not remove
43063 the 32th bit of the CRC, so we can have an upper-case starting letter
43064 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43065 It is ambigous since the CRC was optional and could be followed by
43066 options like EB, EE. So now this routines uses lower-case letter for
43067 the hexadecimal representation. Strange enough only lower case letters
43068 where checked in Scan_ALI (even if this was not a possible case).
43070 * gnatvsn.ads (Library_Version): changed to 3.15a.
43072 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43075 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
43078 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
43079 Add 2001 to copyright notice
43080 (Accumulate_Checksum): Modify to use System.CRC32.
43082 * ali-util.ads: Redo changes of previous revision to continue to use
43083 the word Checksum. Add 2001 to copyright notice.
43085 * ali.adb: Undo some of previous changes, not needed.
43086 Keep the change for lower case letters in the checksum.
43088 * ali.ads: Undo previous change not needed.
43090 * bcheck.adb: Undo most of previous change, not needed.
43091 But do use Checksums_Match for checksum comparison.

43094 But do use Checksums_Match for comparing checksums.
43096 * lib-load.adb: Undo previous change, not needed.
43098 * lib-writ.adb: Undo previous change, not needed.

43118 * sinput.adb: Undo previous change, not needed.
43120 * sinput-l.adb: Undo previous change, not needed.
43122 * sinput.ads: Undo previous change, not needed. Keep only comment
43123 on new checksum algorithm
