1736 Orig_Prev to Prev in the case where the actual is N_Function_Call or
1737 N_Identifier. This was interfering with other cases that are rewritten
1738 as N_Identifier, such as allocators, resulting in passing of the wrong
1739 accessibility level, and based on testing this code is apparently no
1740 longer needed at all.

3912 Is_Remote_Call_Interface to identify RACW types in a stable and
3913 consistent way. We used to rely in this predicate on the privateness of
3914 the designated type and its ancestors, but depending on the currently

3930 Add missing escaping of all-caps word 'CPP' in error messages.
3931 (Build_Discriminated_Subtype): Do not inherit representation clauses
3932 from parent type if subtype already carries them, because they are
3933 inherited earlier during derivation and already include those that may
3934 come from a partial view.

3972 operation of an RACW stub type (these primitives are only executed
3973 through dispatching, never through static calls).
3974 (Collect_Interps): When only one interpretation has been found, set N's
3975 Entity and Etype to that interpretation, otherwise Entity and Etype may
3976 still refer to an interpretation that was ignored by Add_One_Interp,
3977 in which case would end up with being marked as not overloaded but with
3978 an Entity attribute not pointing to its (unique) correct interpretation.

8103 clauses for inherited components of a type extension.
8104 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
8105 an overloadable item if it is a pragma that can apply to multiple
8106 overloadable entities (e.g. Inline) because a pragma cannot be on

8237 subprogram body that acts as its own spec may not have a non-private
8238 WITH clause on a private sibling.
8239 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8240 child unit is a renaming, create an implicit with_clause on that
8241 parent, and not on the unit it renames, to prevent visibility errors

8282 (Process_Subtype): The subtype inherits the Known_To_Have_Preelab_Init
8284 (Derive_Subprograms): Handle derivations of predefined primitives
8285 after all the user-defined primitives to ensure that they are
8286 found in proper order in instantiations.

8288 of Related_Interface to Related_Type.
8289 (Record_Type_Declaration): Minor reordering of calls to decorate the

8300 concurrent tagged type prefix should yield a primitive operation.
8301 (Find_Primitive_Operation): Handle case of class-wide types.
8302 (Analyze_Overloaded_Selected_Component): If type of prefix is
8303 class-wide, use visible components of base type.

8305 (Try_Primitive_Operation, Collect_Generic_Type_Ops): If the type is a
8306 formal of a generic subprogram. find candidate interpretations by
8307 scanning the list of generic formal declarations.:
8308 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
8309 type from a limited_with_clause, and the full view is available, use it
8310 for subsequent semantic checks.

8312 (Find_Primitive_Operation): New function.
8313 (Analyze_Overloaded_Selected_Component): insert explicit dereference
8314 only once if several interpretations of the prefix yield an access type.

8338 Gary Dismukes <dismukes@adacore.com>
8340 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
8341 requeue statement is dispatching. Do not emit an error when the name is
8342 not an entry and the context is a dispatching select. Add code to
8343 perform subtype conformance between the formals of the current entry
8344 and those of the target interface primitive.
8345 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8346 Timed_Entry_Call): Analyze the triggering statement as the first step of
8347 the processing. If this is a dispatching select, postpone the analysis
8348 of all select statements until the Expander transforms the select. This
8349 approach avoids generating duplicate identifiers after the Expander has
8350 replicated some of the select statements. In case the Expander is
8351 disabled, perform regular analysis.
8352 (Check_Triggering_Statement): New routine.
8353 (Analyze_Requeue): Exclude any interpretations that are not entries when
8354 checking overloaded names in a requeue. Also test type conformance for

8944 * ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
8946 (Xref_Record): Change type for Line, since in the case of a reference to
8947 a predefined entity (as happens for array index types), the line is set
8949 Add support for parsing multiple array index types info, or
8950 multiple inherited interfaces info. This information cannot be stored
8951 in Xref_Entity_Record, which only supports a single instance of Tref_*,
8952 and is therefore stored in the list of references instead. It has a
8953 special treatement later on in tools that use this information.
8955 2007-10-15 Tristan Gingold <gingold@adacore.com>
8957 * debug.adb: Document use of -gnatd.a and -gnatd.I

8963 * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
8964 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
8965 care of access to class-wide interface types plus removal of bizarre
8966 conversion of tagged object to access type (reported by Gary
8967 Dismukes). After this patch there is no need to perform any
8968 additional management on these nodes in Expand_Interface_Actuals.
8970 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
8971 that handles use of 'Access and 'Unchecked_Access applied to
8972 actuals covering interface types. Such code is now
8973 centralized in Expand_N_Attribute_Reference.
8975 2007-10-15 Ed Schonberg <schonberg@adacore.com>
8977 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
8978 of tagged types whose ultimate ancestor is a CPP type.
8979 (Freeze_Array_Type): For a packed array type, generate an initialization
8980 procedure if the type is public, to handle properly a client that
8981 specifies Normalize_Scalars.
8983 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
8985 * exp_ch9.adb (Actual_Index_Expression): When the expansion occurs

9003 (passing'Unrestricted_Access of nested subprograms to Sort) with use of
9004 the generic Heap_Sort_G, in order to avoid trampolines.
9006 2007-10-15 Vasiliy Fofanov <fofanov@adacore.com>
9007 Jose Ruiz <ruiz@adacore.com>
9009 * vx_stack_info.c: New file.
9011 * i-forbla-unimplemented.ads: New file.
9013 * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
9014 for unsupported configurations; use it on VMS targets instead of the
9016 (EXTRA_LIBGNAT_SRCS,EXTRA_LIBGNAT_OBJS for VxWorks): Include
9017 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9018 used by VxWorks targets to have access to task-specific data and be
9019 able to extract the stack boundaries for stack checking.
9020 Use system-vms-ia64.ads on ivms.
9022 * Make-lang.in: Update dependencies.
9024 * sysdep.c (__gnat_get_stack_info): Move to a standalone file

9041 95 reserved word in its name.
9042 (Process_Project_Level_Array_Attributes): Process new attribute
9043 Runtime_Library_Dir.
9045 * prj-part.adb (Parse_Single_Project): Do not check the name of the
9046 config project against the user project names.

9061 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9063 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9064 association for an access component, add an association with null as
9065 the expression. Remove testing for array subtypes and the setting in
9066 that case of Ctyp to the array component type, which prevented proper
9067 inclusion of an association for null-initialized arrays. Collapse
9068 condition that tests for array subtypes into just a test of
9069 Is_Partially_Initialized_Type (which already covers arrays anyway).
9071 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>

9080 * sem_ch3.adb (Build_Derived_Concurrent_Type): Set the Is_Constrained
9081 flag of derived concurrent types, taking into account the flag setting
9082 on the parent subtype and any new set of discriminants.
9084 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9086 * sem_ch4.adb: Minor code and comment reformatting.
9087 (Analyze_Allocator): When the designated type of an unconstrained
9088 allocator is a record with unknown discriminants or an array with
9089 unknown range bounds, emit a detailed error message depending on the
9090 compilation mode and whether the designated type is limited.

9144 * gnat_ugn.texi: Add documentation for switches --version and --help
9145 for the GNAT tools gnatbind, gnatlink, gnatmake, gnatchop, gnatname,
9146 gnatxref, gnatfind, gnatls, and gnatclean.

9165 to generate g-soccon-vms.ads.
9167 * atree.adb: Add ??? comment

9223 type of file_info_ptr parameter.
9224 If mapped location support is enabled, create the isomorphic mapping
9225 between source files and line maps.
9226 (Sloc_to_locus): If mapped location support is enabled, translate
9227 source location into mapped location.
9228 (annotate_with_node): Rename into set_expr_location_from_node.

9242 (Applicable_Use): Emit a warning when a package tries to use itself.
9243 (Use_One_Type): Add variable Is_Known_Used. Emit a warning when a type

9252 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9254 * a-calend-vms.adb, a-calend.adb:
9255 Add a section on leap seconds control along with two entities used to
9256 enable and disable leap seconds support. The array Leap_Second_Times is
9257 now constant and contains hard time values pre-generated. Remove
9258 all elaboration code used to populate the table of leap seconds.
9261 Add entity Leap_Seconds_Support to the list of global run-time variables
9262 along with a comment on its usage and values.
9263 (Gen_Adainit_Ada): Add code to generate the declaration and import of

9304 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
9306 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9309 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9311 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9314 * sem_dist.ads: Minor comment fix

9318 2007-09-26 Javier Miranda <miranda@adacore.com>
9319 Eric Botcazou <ebotcazou@adacore.com>
9322 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9323 indirection added to the HT_Link component of the TSD. This is required
9324 to statically allocate the TSD.
9327 Minor reordering of the declarations in the private part. Required to
9328 add a level of indirection to the contents of the TSD component HT_Link.
9329 This is required to statically allocate the TSD.
9331 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9332 Is_Statically_Allocated set from constant objects.
9333 Do not make exported constants created by the compiler volatile.
9334 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9337 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9338 before returning them.

9341 public part of the package.
9342 (Make_DT): Move HT_Link component out of the TSD record. For this
9343 purpose Make_DT now declares a separate object that stores the
9344 HT_Link value, and initializes the TSD component with the address
9345 of this new object. The addition of this level of indirection is
9346 required to statically allocate the TSD because the TSD cannot
9347 have variable components.
9348 (Expand_Interface_Conversion): Improve the expanded code.
9349 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9351 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9352 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9353 if we are building static dispatch tables then we must not generate
9354 extra code to register the primitive because the dispatch table will
9355 be built at the end of the library package; otherwise we notify that
9356 we cannot build the static dispatch table.
9358 2007-09-26 Robert Dewar <dewar@adacore.com>
9360 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9367 tests for controlled type overlay to composites with controlled
9369 (Analyze_Record_Representation_Clause): Add reference for component name
9371 2007-09-26 Javier Miranda <miranda@adacore.com>

9378 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9379 associated with interface types.
9380 Extensive comment fixes regarding flags that appear in all entities. The
9381 documentation is now consistent for all such flags (there were a number
9382 of errors in the documentation in this regard).
9384 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9386 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9387 of these procedures are passed a function call that already has
9388 build-in-place actuals (testing new flag
9389 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9390 the case where processing continues.
9391 (Expand_Call): If the call is generated from a thunk body then we
9392 propagate the extra actuals associated with the accessibility
9393 level of the access type actuals.
9395 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9396 of each extra formal of a protected operation to reference the
9397 corresponding extra formal of the subprogram denoted by the
9398 operation's Protected_Body_Subprogram.
9400 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9401 N_Function_Call nodes.

9407 * debug.adb: Add d.s flag.
9409 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9411 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9412 debug variable so that it won't be initialized when pragma
9413 Initialize_Scalars is in effect.
9415 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9417 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9418 initialization of a full view. This is moved to
9419 Analyze_Package_Specification.
9421 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9422 preelaborable initialization of a full view in entity loop.
9423 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9424 its child units are use-visible only if they are visible child units.
9426 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9427 whether an expression can be used within a type declaration that
9428 requires preelaborable init.
9429 (Check_Components): Replace inline code that does partial checking for
9430 preelaborable default expressions with call to
9431 Is_Preelaborable_Expression.
9432 (Has_Preelaborable_Initialization): In the case of a generic actual
9433 subtype, (that is, Is_Generic_Actual is True), return the result of
9434 applying Has_Preelaborable_Initialization to the generic actual's base
9437 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9439 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a

9441 (Is_Leap): Move the routine to the scope of Week_In_Year.
9442 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9443 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9444 avoids calling Time_Of and Split, thus making it more efficent.
9445 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9447 * g-calend.ads (Week_In_Year): Change comment to reflect new
9450 2007-09-26 Emmanuel Briot <briot@adacore.com>
9452 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9453 Command_Line): New types
9454 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9455 support for defining how switches can be grouped on a command line (as
9456 is the case for -gnatw... for GNAT), and how simple switches can be
9457 used as aliases for more complex switches (-gnatwa is same as
9459 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9460 (Start, Current_*): New subprograms
9461 Added support for parsing an array of strings in addition to the real
9463 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9464 be moved from the body to the private part of the spec.
9465 (*): All subprograms now have an extra parameter with default value to
9466 specify which parser should be used. For backward compatibility, it
9467 defaults to parsing the command line of the application. They were also
9468 modified to properly handle cases where each of the argument does not
9469 start at index 1 (which is always true for Ada.Command_Line, but not
9470 when processing any Argument_List).
9471 (Free): New subprogram
9472 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9473 Argument): New subprograms
9474 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9475 special characters like ':', '=',... are now handled in a single place,
9476 which makes the code more extensible eventually.
9477 (Getopt, Full_Switch): When the switch was returned as part of the
9478 special character '*', make sure it is prepended by the switch character
9479 ('-' in general), so that the application knows whether "foo" or "-foo"
9480 was specified on the command line.
9482 2007-09-26 Florian Villoing <villoing@adacore.com>
9484 * g-dirope.adb (Remove_Dir): In case we are removing directories
9485 recursively, make sure that if an exception is raised during the
9486 processing, the current working directory is reset to its initial
9487 value before propagating the exception.
9489 2007-09-26 Vincent Celier <celier@adacore.com>
9491 * gnatbind.adb: If there are several ALI files specified and there is
9492 a main program to bind, the first ALI is expected to contain the main
9493 subprogram and the names of the binder generated files will be derived
9494 from the first ALI file name.
9495 (Gnatbind): Fix insertion character in invocation of Error_Msg
9497 2007-09-26 Vincent Celier <celier@adacore.com>
9499 * gnatcmd.adb (Check_Files): Do not include sources that have been
9500 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9502 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9504 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9505 information about each of its index types, following the type
9506 reference for its component type.
9508 2007-09-26 Vincent Celier <celier@adacore.com>
9510 * make.adb: (Kill): New procedure (__gnat_kill imported)

9521 2007-09-26 Vincent Celier <celier@adacore.com>
9523 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9525 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9526 Replace components Compiler_Min_Options and Binder_Min_Options with
9527 Compiler_Required_Switches and Binder_Required_Switches in record

9532 * prj-attr.adb: New attributes Required_Switches (<language>) in
9533 packages Compiler and Binder.
9535 * prj-nmsc.adb: Major rewrite of the processing of configuration
9536 attributes for gprbuild. No impact on GNAT tools.
9538 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9539 process configuration attributes: this is done in Prj.Nmsc.Check.
9540 (Recursive_Process): Make a full copy of packages inherited from project
9541 being extended, instead of a shallow copy.
9542 (Process_Project_Tree_Phase_1): New procedure
9543 (Process_Project_Tree_Phase_1): New procedure
9544 (Process): Implementation now uses the two new procedures
9546 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9547 from the project config, not the tree config that no longer exists.
9549 2007-09-26 Vincent Celier <celier@adacore.com>

9573 ancestor of the derived type, the operations are inherited from the
9574 primary dispatch table of the parent.
9575 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9576 when the context is an explicit type conversion.

9873 Thomas Quinot <quinot@adacore.com>
9875 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
9876 create an abstract subprogram in the case of 'Input. For 'Output we now
9877 create a real spec/body when the type is abstract, since it can
9878 potentially be called.
9879 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9880 body for 'Output when the type is abstract (only the creation of the
9881 body for 'Input is excluded when the type is abstract).
9882 (Stream_Operation_OK): Add an additional condition in the return
9883 statement, so that False will be returned for TTS_Stream_Input if the
9884 associated tagged type is an abstract extension. Add comments for
9886 (Expand_N_Object_Declaration): For the case of a shared passive
9887 variable, insert init proc call only after the shared variable
9888 procedures have been processed, because the IP call needs to undergo
9889 shared passive variable reference expansion, which requires these
9890 procedures to be available (and elaborated).
9892 2007-09-10 Vincent Celier <celier@adacore.com>
9894 * prj-env.ads, prj-env.adb (Create_Mapping_File (Language)): Remove
9895 parameter Runtime_Project.
9897 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9899 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
9900 given a box association, the type of the component is discriminated,
9901 and the value of the discriminant is the discriminant of the enclosing
9902 type, retrieve its value from the aggregate itself, where it must have
9905 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
9906 to remove other spurious ambiguities on arithmetic operations involving
9907 literals and addresses, on systems where Address is a visible integer
9908 type, when the operator is called in functional notation.
9909 (Try_Primitive_Operation): Within an instance, a call in prefixed form
9910 is legal when the types match, even if the operation is currently
9913 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9915 * sem_ch12.adb (Build_Local_Package): A formal package with no
9916 associations is legal if all formals have defaults. It is not
9917 equivalent to a formal declared with a box.

10028 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10030 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the

10033 Update the usage of available flag to reflect the addition of Is_Raised.
10034 (Is_Raised, Set_Is_Raised): Bodies of new routines.
10035 (Write_Entity_Flags): Write the status of flag Is_Raised.
10036 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10037 spurious ambiguities when integer literals appear in the context of an
10038 address type that is a visible integer type.
10040 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10041 exceptions never being raised.
10042 (Analyze_Raise_Statement): When analyzing an exception, mark it as being
10045 2007-08-31 Javier Miranda <miranda@adacore.com>
10047 * exp_ch11.adb (Expand_At_End_Handler): Avoid generation of raise
10048 statement when compiling under restriction No_Exceptions_Proparation.
10050 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10052 * exp_ch3.adb (Build_Record_Init_Proc): If there is a static
10053 initialization aggregate for the type, generate itype references for
10054 thetypes of its (sub)components, to prevent out-of-scope errors in gigi.
10056 2007-08-31 Gary Dismukes <dismukes@adacore.com>
10058 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10059 library-level package renaming, pass the declaration associated with
10060 the renaming's special debug variable to Qualify_Entity_Names to ensure
10061 that its encoded name is properly qualified.
10063 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10064 occurring in the list of entities to qualify, and do not attempt to
10065 traverse an entity list in that case. Variables associated with
10066 ` library-level package renamings can now occur in the table.
10068 * exp_dbug.ads: Revise documentation of the encoding for renaming
10071 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
10073 * layout.adb (Layout_Type): Use Underlying_Type to determine whether an
10074 access type points to an unconstrained array.
10076 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10078 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
10081 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect
10082 simple redundant qualifications. The check is performed whenever the
10083 expression is a non-overloaded identifier.
10084 (Resolve_Type_Conversion): Enchance the redundant type conversion check
10085 to include loop parameters.
10086 (Valid_Conversion): Avoid generation of spurious error message.

10090 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10091 concatenations of string literals into a single literal, in order to
10092 avoid very deep recursion in the front end, which was causing stack
10095 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10096 string, and the right operand is a string literal (the case of "" &
10097 "..."), optimize by avoiding copying the right operand -- just use the
10098 value of the right operand directly.
10100 * stringt.adb (Store_String_Chars): Optimize by growing the
10101 String_Chars table all at once, rather than appending characters one by
10103 (Write_String_Table_Entry): If the string to be printed is very long,
10104 just print the first few characters, followed by the length. Otherwise,
10105 doing "pn(n)" in the debugger can take an extremely long time.
10107 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10108 Store_String_Char with Store_String_Chars.
10110 2007-08-31 Vincent Celier <celier@adacore.com>

10123 have not been fully analyzed.
10125 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10127 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10128 flag, for effiency. It is called when analyzing arithmetic operators
10129 and also for actuals in calls that are universal_integers. The flag is
10130 set for the predefined type address, and for any type or subtype
10133 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10134 Universal_Integer, when the formal is a descendent of address and the
10135 call appears in user code.
10136 (Analyze_Selected_Component): if the prefix is a private extension, the
10137 tag component is visible.
10139 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an
10142 2007-08-31 Robert Dewar <dewar@adacore.com>

10188 when compiling for powerpc64-*-linux.
10189 * system-linux-ppc64.ads: New file.
10191 2007-08-22 Krister Walfridsson <cato@df.lth.se>

10196 2007-08-16 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
10198 * misc.c (gnat_type_max_size): Constify.
10200 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10202 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10203 associated with Standard_Debug_Renaming_Type, to be used as the type of
10204 the special variables whose names provide debugger encodings for
10205 renaming declarations.
10207 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10208 (Set_Debug_Renaming_Link): Change to set Node25.
10209 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
10210 (Write_Field25_Name): Add case for E_Variable to output
10211 "Debug_Renaming_Link".
10212 (Write_Field23_Name): Correct the output string for "Limited_View".
10214 * exp_dbug.adb: Add with and use of Tbuild.
10215 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10216 and literal with creation of a variable of type
10217 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10218 and the entity of the renaming declaration.
10219 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10220 part of the name of a variable that has a Debug_Renaming_Link.
10222 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10223 special type to be associated with variables that provide debugger
10224 encodings for renaming declarations.

10227 Ed Schonberg <schonberg@adacore.com>
10228 Javier Miranda <miranda@adacore.com>
10230 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10231 ancestor part given by an aggregate to test for an unchecked conversion,
10232 since this can occur in some cases when the ancestor part is a function
10233 call, and we don't want to fall into the recursive call to this
10234 procedure in that case.
10236 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10237 stream attributes on limited types to account for user-specified
10238 attributes as well as whether Input (resp. Output) becomes available
10239 due to Read (resp. Write) being available for the type. Change Boolean
10240 variable to the more accurate name
10241 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10242 double-"not" predicate at beginning of return statement to more
10243 understandable form.
10245 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10246 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10247 in a block statement and use that as the first statement of the
10248 expanded return rather than incorrectly using the handled sequence as
10249 the first statement.
10251 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10252 operation, generate an explicit freeze node for it rather than
10253 generating extra formals, to ensure that gigi has the proper order of
10254 elaboration for anonymous subtypes in the signature of the subprograms.
10255 (Build_In_Place_Formal): Move assertion to beginning of loop.
10256 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10257 applied to a function call (occurs for some cases of 'Input).
10258 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
10259 applied to a function call (occurs for some cases of 'Input).
10261 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10262 2005, generate an extended return statement enclosing the result object
10265 * freeze.adb (Freeze_Record_Type): Extend the current management of
10266 components that are access type with an allocator as default value: add
10267 missing support to the use of qualified expressions of the
10268 allocator (which also cause freezing of the designated type!)
10269 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10270 dispatching operation, since extra formals may be needed by calls to
10271 build-in-place functions (such as stream 'Input).
10273 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10274 formals for 'Constrained and accessibility level in the case of a
10275 predefined dispatching operation.
10277 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10278 point, no need to find the parent node.
10280 2007-08-16 Javier Miranda <miranda@adacore.com>
10282 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10283 and entry barriers.
10285 2007-08-16 Javier Miranda <miranda@adacore.com>
10287 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10288 is not really required and can introduce regression with the debugger.
10289 The original problem is fixed with the patch written for checks.adb.
10291 2007-08-16 Thomas Quinot <quinot@adacore.com>
10293 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
10294 Range_Check on Allocated_Table.
10296 2007-08-16 Vincent Celier <celier@adacore.com>
10298 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with

10300 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10301 Including_Non_Switch set to False.
10303 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10304 parameter Including_Non_Switch, defaulted to True. When
10305 Including_Non_Switch is False, options that are not switches and
10306 appear as relative path are not converted to absolute paths.

10330 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10331 generic for an enclosing instance is a global reference, even though
10332 its scope is the enclosing instance.

10358 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10359 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10360 the statement which is being resolved comes from a predefined library
10361 unit, all non-predefined library interpretations are skipped.
10362 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10363 but the "&" is user defined, give an error, because the folding would

10367 the parser has folded a long sequence of concatenations of string
10370 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10371 and "JMP_BUF" variables as artificial.
10372 (N_String_Literal): Do not use alloca for very long string literals. Use
10373 xmalloc/free instead. Otherwise the stack might overflow.

10418 Ed Schonberg <schonberg@adacore.com>
10420 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10421 Suppress unmodified in-out parameter warning in some cases
10422 This patch is a also fairly significant change to the way suppressible
10423 checks are handled.
10425 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10426 needed for access to concurrent record types generated by the expander.
10427 (Generate_Range_Check): When generating a temporary to capture the
10428 value of a conversion that requires a range check, set the type of the
10429 temporary before rewriting the node, so that the type is always
10430 properly placed for back-end use.
10431 (Apply_Float_Conversion_Check): Handle case where the conversion is
10433 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10434 for a protected type in order to examine its discriminants.

10441 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10442 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10443 tests optimized out.
10445 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10446 (Get_Allocator_Final_List): For the case of an anonymous access type
10447 that has a specified Associated_Final_Chain, do not go up to the
10449 (Expand_N_Type_Conversion): Test for the case of renamings of access
10450 parameters when deciding whether to apply a run-time accessibility
10452 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10453 aggregate code before allocator, and ahead of declaration for
10454 temporary, to prevent access before elaboration when the allocator is
10455 an actual for an access parameter.
10456 (Expand_N_Type_Conversion): On an access type conversion involving an
10457 access parameter, do not apply an accessibility check when the
10458 operand's original node was an attribute other than 'Access. We now
10459 create access conversions for the expansion of 'Unchecked_Access and
10460 'Unrestricted_Access in certain cases and clearly accessibility should
10461 not be checked for those.
10463 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10464 includes a type conversion of a packed component that has been expanded,
10465 recover the original expression for the object, and use this expression
10466 in the post-call assignment statement, so that the assignment is made
10467 to the object and not to a back-end temporary.
10468 (Freeze_Subprogram): In case of primitives of tagged types not defined
10469 at the library level force generation of code to register the primitive
10470 in the dispatch table. In addition some code reorganization has been
10471 done to leave the implementation clear.
10472 (Expand_Call): When expanding an inherited implicit conversion,
10473 preserve the type of the inherited function after the intrinsic
10474 operation has been expanded.
10476 * exp_ch2.ads, exp_ch2.adb
10477 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10478 of an entry formal appearing in an assignment statement does not assign
10480 (Expand_Current_Value): Instead of calling a routine to determine
10481 whether the prefix of an attribute reference should be optimized or
10482 not, prevent the optimization of such prefixes all together.
10484 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10485 component whose prefix is known to be of an access type is an implicit
10486 dereference and does not assign to the prefix.
10488 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10489 Robert Dewar <dewar@adacore.com>
10491 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10492 itype is visited, make an entry into table to link associated node and
10494 Add comments and correct harmless error in Build_NCT_Hash_Tables
10495 (Array_Aggr_Subtype): Associate each itype created for an index type to
10496 the corresponding range construct, and not to the aggregate itself. to
10497 maintain a one-to-one correspondence between itype and its associated
10498 node, to prevent errors when complex expression is copied.
10499 Fix mishandling of multiple levels of parens
10501 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10502 treatment of limited views uniform for all visible declarations in a
10503 limited_withed package.
10504 (New_Copy_Tree): If hash table is being used and itype is visited,
10505 make an entry into table to link associated node and new itype.
10506 (Resolve_Record_Aggregate): Do not add an others box association for a
10507 discriminated record component that has only discriminants, when there
10508 is a box association for the component itself.
10510 * par-ch4.adb: Fix mishandling of multiple levels of parens
10512 2007-08-14 Robert Dewar <dewar@adacore.com>

10548 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
10549 to make treatment of limited views uniform for all visible declarations
10550 in a limited_withed package.
10551 Improve warnings for in out parameters
10552 (Set_Related_Interaface/Related_Interface): Allow the use of this
10553 attribute with constants.
10554 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10555 Warn on duplicate pragma Preelaborable_Initialialization
10557 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10558 generation of a freezing node to ensure proper management of null
10559 excluding access types in the backend.
10560 (Create_Extra_Formals): Test base type of the formal when checking for
10561 the need to add an extra accessibility-level formal. Pass the entity E
10562 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10563 originally being done in a couple of cases), to ensure that the
10564 Extra_Formals list gets set on the entity E when the first entity is
10566 (Conforming_Types): Add missing calls to Base_Type to the code that
10567 handles anonymous access types. This is required to handle the
10568 general case because Process_Formals builds internal subtype entities
10569 to handle null-excluding access types.
10570 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10571 functions that need it, even when not marked Requires_Overriding.
10572 Improve warnings for in out parameters
10573 (Analyze_Function_Return): Warn for disallowed null return
10574 Warn on return from procedure with unset out parameter
10575 Ensure consistent use of # in error messages
10576 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10577 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10578 the implicit conversion of the expression done for anonymous access
10579 types. This is required to generate the code of the null excluding
10580 check (if required).
10582 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10583 A formal parameter is never publicly referenceable outside of its body.
10584 (Check_References): For an unreferenced formal parameter in an accept
10585 statement, use the same warning circuitry as for subprogram formal
10587 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10588 Output_Unreferenced_Messages, containing the part of that routine that
10589 is now reused for entry formals as described above.
10590 (Goto_Spec_Entity): New function
10591 (Check_References): Do not give IN OUT warning for dispatching operation
10592 Improve warnings for in out parameters

10600 Gary Dismukes <dismukes@adacore.com>
10602 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10603 (Expand_N_Attribute_Reference): Further unify the handling of the
10604 three forms of access attributes, using common code now for all three
10605 cases. Add a test for the case of applying an access attribute to
10606 an explicit dereference when the context is an access-to-interface
10607 type. In that case we need to apply the conversion to the prefix
10608 of the explicit dereference rather than the prefix of the attribute.
10609 (Attribute_Version, UET_Address): Set entity as internal to ensure
10610 proper dg output of implicit importation.
10611 (Expand_Access_To_Type): Removed.
10612 (Expand_N_Attribute_Reference): Merge the code from the three cases
10613 of access attributes, since the processing is largely identical for
10614 these cases. The substantive fix here is to process the case of a
10615 type name prefix (current instance case) before handling the case
10616 of interface prefixes.

10621 Robert Dewar <dewar@adacore.com>
10623 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10624 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10625 type that is an anonymous access to controlled object, establish
10626 an associated finalization chain to avoid corrupting the global
10627 finalization list when a dynamically allocated object designated
10628 by such a component is deallocated.
10629 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10630 functions that need it, even when not marked Requires_Overriding.
10631 (Initialize_Tag): Replace call to has_discriminants by call to
10632 Is_Variable_Size_Record in the circuitry that handles the
10633 initialization of secondary tags.
10634 (Is_Variable_Size_Record): New implementation.
10635 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10636 Suppress_Initialization pragma for a derived type.
10637 (Is_Variable_Size_Record): New subprogram.
10638 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10639 initial version of this routine and also fixes problems causing
10640 incomplete initialization of the table of interfaces.
10641 (Build_Init_Procedure): Improve the generation of code to initialize the
10642 the tag components of secondary dispatch tables.
10643 (Init_Secondary_Tags): New implementation that simplifies the previous
10644 version of this routine.
10645 (Make_DT): Add parameter to indicate when type has been frozen by an
10646 object declaration, for diagnostic purposes.
10647 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10648 diagnose attemps to freeze a subprogram when some untagged type of its
10649 profile is a private type whose full view has not been analyzed yet.
10650 (Freeze_Array_Type): Generate init proc for packed array if either
10651 Initialize or Normalize_Scalars is set.
10652 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10653 constructing the new profile, copy the null_exclusion indicator for each
10654 parameter, to ensure full conformance of the new body with the spec.
10656 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10657 Create wrappers for constructor functions that need it, even when not
10658 marked Requires_Overriding.
10659 (Covers): Handle properly designated types of anonymous access types,
10660 whose non-limited views are themselves incomplete types.
10661 (Add_Entry): Use an entity to store the abstract operation which hides
10663 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10664 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10665 initialization aggregate.
10666 (Function_Interp_May_Be_Hidden): Rename to
10667 Function_Interp_Has_Abstract_Op.
10668 (Has_Compatible_Type): Remove machinery that skips interpretations if
10669 they are labeled as potentially hidden by an abstract operator.
10670 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10671 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10672 (Write_Overloads): Output the abstract operator if present.
10673 (Add_Entry): Before inserting a new entry into the interpretation table
10674 for a node, determine whether the entry will be disabled by an abstract

10677 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10679 (Function_Interp_May_Be_Hidden): New routine.
10680 (Has_Compatible_Type): Do not consider interpretations hidden by
10681 abstract operators when trying to determine whether two types are
10683 (Has_Hidden_Interp): New routine.
10684 (Set_May_Be_Hidden_Interp): New routine.

10690 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
10691 types declared in the declarative part of a nested package body or in
10692 the proper body of a stub.
10693 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10694 of the same dispatch table slot to renamed primitives.
10695 (Make_Select_Specific_Data_Table): Handle private types.
10696 (Tagged_Kind): Handle private types.
10697 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10698 output of implicit importation and exportation.
10699 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10700 first formal of the thunk is always associated with the controlling
10701 type. In addition perform the following code cleanup: remove formal
10702 Thunk_Alias which is no longer required, cleanup evaluation of the
10703 the controlling type, and update the documentation.
10704 Replace occurrence of Default_Prim_Op_Count by
10705 Max_Predef_Prims. Addition of compile-time check to verify
10706 that the value of Max_Predef_Prims is correct.
10707 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10708 (Make_DT): Add parameter to indicate when type has been frozen by an
10709 object declaration, for diagnostic purposes.
10710 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10711 construction of statically allocated dispatch tables.
10712 (Make_DT): In case of library-level tagged types export the declaration
10713 of the primary tag. Remove generation of tags (now done by Make_Tags).
10714 Additional modifications to handle non-static generation of dispatch
10715 tables. Take care of building tables for asynchronous interface types
10716 (Make_Tags): New subprogram that generates the entities associated with
10717 the primary and secondary tags of Typ and fills the contents of Access_
10718 Disp_Table. In case of library-level tagged types imports the forward
10719 declaration of the primary tag that will be declared later by Make_DT.
10720 (Expand_Interface_Conversion): In case of access types to interfaces
10721 replace an itype declaration by an explicit type declaration to avoid
10722 problems associated with the scope of such itype in transient blocks.

10725 Ed Schonberg <schonberg@adacore.com>
10726 Javier Miranda <miranda@adacore.com>
10728 * exp_util.ads, exp_util.adb:
10729 This patch replaces a number of occurrences of explicit tests for N_Null
10730 with calls to Known_Null. This improves tracking of null values, since
10731 Known_Null also catches null constants, and variables currently known to
10732 be null, so we get better tracking.
10733 (Ensure_Defined): create an itype reference only in the scope of the
10735 (Side_Effect_Free): A selected component of an access type that
10736 denotes a component with a rep clause must be treated as not
10737 side-effect free, because if it is part of a linked structure its
10738 value may be affected by a renaming.
10739 (Expand_Subtype_From_Expr): For limited objects initialized with build
10740 in place function calls, do nothing; otherwise we prematurely introduce
10741 an N_Reference node in the expression initializing the object, which
10742 breaks the circuitry that detects and adds the additional arguments to
10743 the called function. Bug found working in the new patch for statically
10744 allocated dispatch tables.
10745 (Is_Library_Level_Tagged_Type): New subprogram.
10746 (Remove_Side_Effects): If the expression of an elementary type is an
10747 operator treat as a function call.
10748 (Make_Literal_Range): If the index type of the array is not integer, use
10749 attributes properly to compute the constraint on the resulting aggregate
10752 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10753 class-wide type whose base type is an incomplete private type, leave
10754 class-wide type unfrozen so that freeze nodes can be generated
10755 properly at a later point.
10756 (Freeze_Entity, array case): Handle case of pragma Pack and component

11385 (Set_Item): When the new item is an element of the currently allocated
11386 table passed by reference, save a copy on the stack if we're going
11387 to reallocate. Also, in Table.Set_Item, make sure we test the proper
11388 variable to determine whether to call Set_Last.

11401 Thomas Quinot <quinot@adacore.com>
11403 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11404 derived type with interface progenitors use the analyzed formal as the
11405 parent of the actual, to create renamings for all the inherited
11406 operations in Derive_Subprograms.
11407 (Collect_Previous_Instances): new procedure within of
11408 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11409 unit being loaded, to ensure that the generation of global symbols is
11410 consistent in different compilation modes.
11411 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11412 takes progenitor types into account.
11413 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11414 traversing over the primitives of the formal and actual types to locate
11415 any abstract subprograms of the actual type that correspond to a
11416 nonabstract subprogram of the formal type's ancestor type(s), and issue
11417 an error if such is found.
11418 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11419 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11420 Remove bogus guard around calls to Inherit_Context.
11421 (Reset_Entity): If the entity is the selector of a selected component
11422 that denotes a named number, propagate constant-folding to the generic
11423 template only if the named number is global to the generic unit.
11424 (Set_Instance_Env): Only reset the compilation switches when compiling
11425 a predefined or internal unit.
11427 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11429 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
11430 parameter to determine whether operation applies to the prefix.
11431 (Complete_Object_Operation): If actual has an access type and
11432 controlling formal is not an in_parameter, reject the actual if it is
11433 an access_to_constant type.
11434 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11435 type, the candidate operations are found in the scope of declaration of
11436 the type, because the type has no primitive subprograms.
11437 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11438 a private extension, only examine visible components before trying to
11439 analyze as a prefixed call.
11440 Change Entity_List to Type_To_Use, for better readability.
11441 (Has_Fixed_Op): Use base type when checking whether the type of an
11442 operator has a user-defined multiplication/division
11443 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
11444 user-defined operators are available for fixed-point types.

11447 Ed Schonberg <schonberg@adacore.com>
11449 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
11450 formal At_Any_Place indicating, when True, that we want to test for
11451 availability of the stream attribute at any place (as opposed to the
11452 current visibility context only).
11453 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11454 purpose of enforcing E.2.2(8) only if it is not available at any place.
11455 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11456 when checking the legality of an extension aggregate in a preelaborable
11457 package. Treat the literal null as a valid default expression in a
11458 component declaration for a type with preelaborable initialization.
11459 A limited interface is a legal progenitor for the designated type of a
11460 remote access to class-wide type.

11468 (Find_Direct_Name): Add comment about Generate_Reference incorrectly
11469 setting the Referenced_As_LHS flag for entities that are implicitly
11471 (Find_Type): If the type is an internally generated incomplete type,
11472 mark the full view as referenced, to prevent spurious warnings.
11473 (Find_Selected_Component, Has_Components): Handle properly non-limited
11474 views that are themselves incomplete types.
11475 Handle interfaces visible through limited-with clauses.
11476 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11477 subprogram generic actual for which we have generated a renaming.
11478 Warn when the renaming introduces a homonym of
11479 the renamed entity, and the renamed entity is directly visible.

11485 appear in the subtree to the current allocator if it is not a static
11487 (Resolve_Allocator): Perform cleanup if resolution has determined that
11488 the allocator is not a coextension.
11489 (Resolve): Skip an interpretation hidden by an abstract operator only
11490 when the type of the interpretation matches that of the context.
11491 (Resolve): When looping through all possible interpretations of a node,
11492 do not consider those that are hidden by abstract operators.
11493 (Resolve_Actuals): When verifying that an access to class-wide object
11494 is an actual for a controlling formal, ignore anonymous access to
11495 subprograms whose return type is an access to class_wide type.
11496 (Resolve_Slice): If the prefix of the slice is a selected component
11497 whose type depends on discriminants, build its actual subtype before
11498 applying range checks on the bounds of the slice.
11499 (Valid_Conversion): In an instance or inlined body, compare root types,
11500 to prevent anomalies between private and public views.
11501 (Resolve): Improve error message for ambiguous fixed multiplication
11502 expressions that involve universal_fixed multiplying operations.

11522 elabration statements, register the package with the name server
11523 at the beginning, not at the end, of the elaboration statements so
11524 that they can create remote access to subprogram values that designate
11525 remote subprograms from the package.
11527 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
11529 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
11530 values to compute the number of seconds since the Unix Epoc in order to

12653 an unconstrained array type, and the expression is a slice, use the
12654 bounds of the slice to construct the required constraint checks.
12655 Improve NOT NULL error messages

12673 Arnaud Charlet <charlet@adacore.com>
12675 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12676 applicable to types that have the With_Type flag set. Returns the
12677 non-limited view of the type, if available, otherwise the type itself.
12678 For class-wide types, there is no direct link in the tree, so we have
12679 to retrieve the class-wide type of the non-limited view of the Etype.
12680 New attributes Static_Initialization and Static_Elaboration_Desired.
12681 Remove the pragma Thread_Body, and the associated flag
12682 Is_Thread_Body in entities, and all related code.

12696 (Root_Type): Handle properly subtypes of class-wide-types.
12699 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12700 class-wide types visible through limited-with clauses.
12701 (Try_Primitive_Operation): When examining all primitive operations of a
12702 tagged type, do not consider subprograms labeled as hidden unless they
12703 belong to a private generic type with a tagged parent.
12704 (Try_Object_Operation): Extensive rewriting, to handle properly various
12705 overloading cases, when several ancestors may have class-wide operations
12706 that are possible candidates, and when the overloaded functions return
12707 array types and have defaulted parameters so that the call may be
12708 interpreted as an indexing.
12709 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12710 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12711 successive actuals before analyzing the call itself.
12712 (Try_Primitive_Operation): A primitive operation is compatible with the
12713 prefix if the prefix has a synchronized type and the type of the formal
12714 is its corresponding record, as can be the case when the primitive
12715 operation is declared outside of the body of the type.
12716 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12717 perform homonym traversal, looking for class-wide operation matches
12718 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12719 access parameters are now restricted to anonymous access types.
12720 (Mark_Allocator): An allocator with a discriminant association parent is
12722 (Try_One_Prefix_Interpretation): If the type of the object is
12723 incomplete, as can be happen when it is a limited view obtained through
12724 a limited_with_clause, the selected component is not part of a prefixed
12726 (Complete_Object_Operation): Diagnose properly an object that is not
12727 aliased when the corresponding controlling formal is an access
12729 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12730 ambiguous calls in prefixed notation, where two primitives differ only
12731 in that the controlling argument of one is an access parameter.
12733 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12734 whether a function that returns an unconstrained type can be inlined.
12735 (Process_Formals): Diagnose properly the illegal use of an incomplete
12736 type in the profile of an access_to_subprogram declaration.
12737 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12738 operations are attached to the corresponding record.
12739 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12740 When processing a primitive of a concurrent type which implements an
12741 interface change the type of all controlling formals to that of the
12742 corresponding record type.
12743 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12744 to determine the tagged type to which a primitive belongs.
12745 (Check_Conventions): Capture condition to ignore a primitive operation
12746 (which is shared between the loop in Check_Conventions and the one in
12747 Check_Convention) in a new local function Skip_Check.
12748 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12749 confusion with Check_Conventions' own Prim_Op local variable.
12750 (Create_Extra_Formals): Test for a tagged result type rather than a
12751 controlling result when determining whether to add a BIP_Alloc_Form
12752 formal and a BIP_Final_List formal to the function.
12753 (Check_Conformance); For parameters that are anonymous access types,
12754 subtype conformance requires that the not null and the constant
12755 indicators must match
12756 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12757 to retrieve the appropriate type when processing a concurrent type
12758 declared within a generic. Minor comment reformatting. Change invocation
12759 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12761 (Analyze_Subprogram_Body): If the return type of a function is an
12762 anonymous access to the limited view of a class-wide type, and the
12763 non-limited view of the type is available, update the type of the
12764 function so that code can be generated.
12765 (Process_Formals): In case of access-subtype itype whose designated
12766 type is also an itype (situation that happens now with access to
12767 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12768 attribute to avoid backend problems.
12769 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12770 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12771 anonymous types' designated types are same before testing
12772 Subtypes_Statically_Match.
12773 (Create_Extra_Formals): Test for a named access parameter that is a
12774 controlling formal as an additional condition for adding an
12775 accessibility level formal. This can occur in the subp type created for
12776 dispatching calls in Expand_Dispatching_Call, and allows calling
12777 Create_Extra_Formals from that procedure rather than special-casing the
12778 extra formals there.
12779 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12780 when the function has a controlling result.
12781 (Check_Returns): Add much more knowledge of the optimization of local
12782 raise statements to gotos, to retain proper warnings in this case.
12783 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12784 nodes when looking for last statement.
12786 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12787 class-wide types visible through limited with clauses.
12788 (Add_One_Interp): If the operands are anonymous access types, the
12789 predefined operator on universal_access is immediately visibles
12790 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12791 other anonymous access types.
12792 (Disambiguate): Take into account CIL convention.
12793 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12795 2007-06-06 Robert Dewar <dewar@adacore.com>

12800 Fix lower bound of tables.
12803 * nlists.adb: Ditto.

12812 * exp_aggr.ads, exp_aggr.adb:
12813 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12814 in extension aggregates.
12815 (Flatten): Other conditions being met, an aggregate is static if the
12816 low bound given by component associations is different from the low
12817 bound of the base index type.
12818 (Packed_Array_Aggregate_Handled): If the component type is itself a
12819 packed array or record, the front-end must expand into assignments.
12820 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12821 Init_Pr, instead of Ancestor_Is_Expression.
12822 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12823 coextension chain root, either generate a list controller or use the
12824 already existing one.
12825 (Static_Array_Aggregate): New procedure to construct a positional
12826 aggregate that can be handled by the backend, when all bounds and
12827 components are compile-time known constants.
12828 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12829 types covering interface types into assignments.
12830 (Replace_Type): move to Build_Record_Aggr_Code.
12831 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12832 interface type, convert to the definite type of the aggregate itself,
12833 so that needed components are visible.
12834 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12835 components and the context is an extended return statement do not
12836 create a transient block for it, to prevent premature finalization
12837 before the return is executed.
12838 (Gen_Assign): Do not generate a call to deep adjust routine if the
12839 component type is itself an array of controlled (sub)-components
12840 initialized with an inner aggregate.
12841 (Component_Check): New name for Static_Check. This name is now more
12842 appropriate, and documentation is added which was missing.
12843 (Component_Check): Add test for bit aligned component value
12844 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12845 Tagged_Comps, name is more appropriate given added function below.
12846 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

12850 Robert Dewar <dewar@adacore.com>
12852 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12853 Terminated: Add unchecked type conversion from System.Address to
12854 System.Tasking.Task_Id when calling the predefined primitive
12856 Disable new Ada 05 accessibility check for JVM.NET targets, which
12857 cannot be implemented in a practical way.
12858 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12859 the sources always references the tag of the actual object. Therefore,
12860 if 'Tag is applied in the sources to class-wide interface objects we
12861 generate code that displaces "this" to reference the base of the object.
12862 (Expand_N_Attribute_Reference, case Size): Return specified size if
12863 known to front end.
12864 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12865 has code that displaces the pointer of the object to manage interface
12866 types. However this code must not be executed when the prefix is a
12867 subprogram. This bug caused the wrong expansion of the internally
12868 generated assignment that fills the dispatch table when the primitive
12869 is a function returning a class-wide interface type.
12870 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12871 Set_Attribute_Name for Name_Unaligned_Valid.

12874 Gary Dismukes <dismukes@adacore.com>
12876 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12877 If the initialization is the equivalent aggregate of the initialization
12878 procedure of the type, do not remove it.
12879 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12880 initialized to null from having their expression reset to empty and

12902 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12903 constrained subtype for a nominal unconstrained type, use its base type
12904 to check for conformance with the context.
12905 (Resolve_Attribute): Remove test of the access type being associated
12906 with a return statement from condition for performing accessibility
12907 checks on access attributes, since this case is now captured by
12908 Is_Local_Anonymous_Access.
12909 (Analyze_Access_Attribute): Set Address_Taken on entity
12910 (Analyze_Attribute, case Address): Set Address_Taken on entity
12911 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
12912 validating an access attribute whose prefix is a current instance.
12913 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
12914 applied to dispatching operations, if freezing is required then we set
12915 the attribute Has_Delayed_Freeze in the prefix's entity.
12916 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
12917 current scope if access of local subprogram taken
12918 (Analyze_Access_Attribute): Check legality of self-reference even if the
12919 expression comes from source, as when a single component association in
12920 an aggregate has a box association.
12921 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
12922 the prefix if it is a protected operation and the attribute is
12923 Unrestricted_Access.
12924 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
12925 reference to the base type of the context, to force a constraint check
12926 when the context is an access subtype with an explicit constraint.
12927 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
12928 node is rewritten as an interface conversion. leave unanalyzed after
12929 resolution, to ensure that type checking against the context will take

12936 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
12937 wrapper when the full view of the controlling type of an inherited
12938 function that dispatches on result implements interfaces.
12939 (Expand_N_Object_Declaration): In cases where the type of the
12940 declaration is anonymous access, create finalization list for it.
12941 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
12942 if the object has no explicit initialization, to match description of
12943 functionality of pragam Persistent_BSS.

12945 new function to build static aggregates, to replace initialization call
12946 when static initialization is desired.
12947 (Freeze_Type): Generate a list controller for an access type whenever
12948 its designated type has controlled anonymous access discriminants.
12949 (Build_Equivalent_Aggregate): New procedure to compute a static
12950 aggregate to be used as default initialization for composite types,
12951 instead of a generating a call to the initialization procedure for the
12953 (Build_Initialization_Call): When available, replace a call to the
12954 initialization procedure with a copy of the equivalent static aggregate
12956 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
12957 declarations for objects of a class-wide interface type, rather than
12958 just identifiers, to prevent visibility problems.
12959 (Expand_N_Object_Declaration): When expanding the declaration for an
12960 object of a class-wide interface type, preserve the homonym chain of
12961 the original entity before exchanging it with that of the generated
12962 renaming declaration.
12963 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
12964 active, because there is no way to handle the exception.
12965 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
12966 to do a minimum decoration of the Access_Disp_Table list.
12967 (Expand_Record_Controller): Avoid the addition of the controller between
12968 the component containing the tag of a secondary dispatch table and its
12969 adjacent component that stores the offset to the base of the object.
12970 This latter component is only generated when the parent type has
12971 discriminants ---documented in Add_Interface_Tag_Components).
12972 (Apply_Array_Size_Check): Removed, no longer needed.
12973 (Expand_N_Full_Type_Declaration): If the type has anonymous access
12974 components, create a Master_Entity for it only if it contains tasks.
12975 (Build_Init_Procedure): Suppress the tag assignment compiling under
12977 (Freeze_Record_Type): Remove code associated with creation of dispatch
12979 (Init_Secondary_Tags): Update type of actuals when generating calls to
12980 Ada.Tags.Set_Offset_To_Top
12981 (Stream_Operation_OK): Disable use of streams compiling under no
12983 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
12984 if Has_Init_Expression set.
12985 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
12986 Register_Primitive, which provides the same functionality.
12987 (Requires_Init_Proc): Return false in case of interface types.
12988 (Add_Secondary_Tables): Use the new attribute Related_Interface to
12990 (Predefined_Primitive_Freeze): Do not assume that an internal entity
12991 is always associated with a predefined primitive because the internal
12992 entities associated with interface types are not predefined primitives.
12993 Therefore, the call to Is_Internal is replaced by a call to the
12994 function Is_Predefined_Dispatching_Operation.
12995 (Make_Eq_If): When generating the list of comparisons for the
12996 components of a given variant, omit the controller component that is
12997 present if the variant has controlled components.
12999 2007-06-06 Javier Miranda <miranda@adacore.com>
13000 Hristian Kirtchev <kirtchev@adacore.com>
13001 Bob Duff <duff@adacore.com>
13003 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13004 handle the creation of finalization lists and calls for nested
13005 coextensions when the root of the chains is part of a return statement.
13006 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13008 (Expand_Record_Equality): Skip components that are interface types.
13009 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13010 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13011 with Rewrite_Coextension. Change the condition for detecting coextension
13013 (Is_Local_Access_Discriminant): Removed.
13014 (Rewrite_Coextension): New routine which rewrites a static coextension
13015 as a temporary and uses its unrestricted access in the construction of
13017 (Complete_Coextension_Finalization): New routine. Generate finalization
13018 attachment calls to all delayed coextensions.
13019 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13020 the allocator is not a coextension itself and has delayed coextensions.
13021 If the current allocator is controlled, but also a coextension, delay
13022 the generation of the finalization attachment call.
13023 Rename local variable "Node" to "Nod" in order to avoid confusion with
13025 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13026 limited types that are not inherently limited. Such an allocator is
13027 illegal, but is generated by the expander for a return statement, to
13028 copy the result onto the secondary stack. This is the only case where a
13029 limited object can be copied. Generate code to displace the pointer
13030 to the object if the qualified expression is a class-wide interface
13031 object. Such displacement was missing and hence the copy of the object
13033 (Apply_Accessibility_Check): Handle allocated objects initialized in
13035 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13036 and Expand_Allocator_Expression. Allocating class-wide interface objects
13037 this routine displaces the pointer to the allocated object to reference
13038 the component referencing the corresponding secondary dispatch table.
13039 Expand_Allocator_Expression): Add missing support to allocate class-wide
13040 interface objects initialized with a qualified expression.
13041 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13042 function result type, and use the finalization list associated with the
13043 function scope in that case (such an anonymous type should not be
13044 treated like an access parameter's type).
13046 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13047 Gary Dismukes <dismukes@adacore.com>
13048 Javier Miranda <miranda@adacore.com>
13050 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13051 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13052 required exception handler.
13053 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13054 properly the case of a function whose return type is a limited
13055 class-wide interface type. Modify the code of the accessibility
13056 check to handle class-wide interface objects. In this case we need to
13057 displace "this" to reference the primary dispatch table to get access
13058 to the TSD of the object (to evaluate its accessibility level).
13059 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13060 rather than a controlling result as one of the conditions for
13061 generating tests of the implicit BIP_Alloc_Form formal. The
13062 initialization assignment is also handled according to whether the
13063 result is tagged instead of controlling.
13064 In the case where the init assignment is inserted in the "then" part of
13065 the allocation conditional, rewrite the target to be a dereference of
13066 the implicit BIP_Object_Access formal.
13067 If the returned value is unconstrained and created on the secondary
13068 stack, mark the enclosing block and function so that the secondary
13069 stack is not reclaimed on return.
13070 Treat returns from functions with controlling results similarly to
13071 returns from functions with unconstrained result subtypes.
13072 If the object returned is unconstrained, and an allocator must be
13073 created for it, analyze the allocator once the block for the extended
13074 return is installed, to ensure that finalizable components
13075 of the expression use the proper finalization list. Guard the call to
13076 Move_Final_List with a check that there is something to finalize.
13077 (Make_Tag_Ctrl_Assignment): Use "old" handling
13078 of controlled type assignment for virtual machines, since new code uses
13079 unsupported features (such as direct access to bytes in memory).
13081 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13082 Ed Schonberg <schonberg@adacore.com>
13084 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13085 accessibility actual, check for the case of an aliased object that has
13086 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13087 we fall into processing for the attribute rather than the name of the
13089 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13090 formal has its address taken in the body, create a temporary to capture
13091 value. If the return type is a limited interface, do not treat the
13092 return value as Controlled.
13093 (Is_In_Place_Function): If the return type is a limited interface,
13094 treat as returning in place. The actual returned object may not always
13095 be limited, but the caller has to assume that it is returned in place.
13096 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13097 context of an allocator, use the correct finalization chain (that is,
13098 the chain belonging to the access type, rather than the chain belonging
13099 to the current scope).
13100 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13101 result type rather than a controlling result as a precondition for
13102 adding an allocation form actual to a build-in-place call.
13103 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13104 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13105 primitive in the dispatch tables. This work is now done by Make_DT when
13106 the type is frozen.
13107 (Register_Predefined_DT_Entry): Removed.
13108 (Add_Return): If end label is not present, use sloc of last statement
13109 for generated return statement in procedure, for better gdb behavior
13111 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13112 object address nodes to ensure proper processing by routines like
13114 (Expand_Call): Fix generation of validity check for parameter
13115 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13116 the allocation form parameter if the result subtype is constrained,
13117 except when the function has a controlling result.
13118 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13119 rather than Is_Controlled and Has_Controlled_Component, since we want to
13120 include class-wide result types in this treatment. Also test for a
13121 controlling result, since that also requires passing a finalization
13123 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13124 even when the result subtype is constrained, to handle calls involving
13125 controlling results.
13126 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13127 is now called even when the result subtype is constrained, to handle
13128 calls involving controlling results.
13129 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13130 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13131 now performs the test).
13132 (Make_Build_In_Place_Call_In_Object_Declaration):
13133 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13134 constrained, to handle calls involving controlling results.
13135 (Add_Return): Accomodate rewritten pattern from local raise to goto
13136 transformation, so that we still recognize an transfer statement
13137 and do the right thing here in that case.
13138 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13139 and end of subprogram code.
13140 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13141 support for primitives that are functions (without formals) with a
13142 controlling result.
13143 (Inherited_From_Formal): If the actual subtype has not generic parent
13144 type, it is not an actual for a formal derived type, and there is no
13145 operation to inherit from the formal.
13147 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13148 Thomas Quinot <quinot@adacore.com>
13150 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13151 inserted cleanup code appropriately for GDB use.
13152 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13153 exception handler for Deep_Adjust or Deep_Finalize.
13154 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13155 Raise_From_Controlled_Operation is available, use a call to that
13156 subprogram instead of a plain "raise Program_Error" node to raise
13157 Program_Error if an exception is propagated from an Adjust or Finalize
13159 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13160 appears in the optional statement list of a triggering alternative, the
13161 scope actions can be inserted directly there, and not in the list that
13162 includes the asynchronous select itself.
13164 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13165 Robert Dewar <dewar@adacore.com>
13166 Hristian Kirtchev <kirtchev@adacore.com>
13168 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13169 generated exception handler appropriately when debugging generated code.
13170 Deal properly with No_Exception_Propagation restriction mode.
13171 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13172 System.Address to System.Tasking.Task_Id when processing the result of
13173 the predefined primitive _disp_get_task_id.
13174 (Expand_N_Asynchronous_Select): Clarify comment.
13175 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13176 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13177 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13178 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13179 privals and for generated call to Complete_Entry_Body, for better gdb
13181 (Copy_Result_Type): Utility to construct a parameter and result profile
13182 for protected functions whose return type is an anonymous access to
13184 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13186 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13187 point when the local-raise-to-goto transformation has taken place.
13189 2007-06-06 Javier Miranda <miranda@adacore.com>
13190 Nicolas Setton <setton@adacore.com>
13192 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13193 functionality when the backend is generating code.
13194 Otherwise any serious error
13195 reported by the backend calling the frontend routine Error_Msg
13196 changes the Compilation_Mode to Check_Semantics, disables the
13197 functionality of this routine and causes the generation of
13198 spureous additional errors.
13200 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13201 debugging information now generated by the compiler for fat-pointer
13203 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13205 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13207 2007-06-06 Thomas Quinot <quinot@adacore.com>
13209 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13210 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13211 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13212 For a remote call to a function with a classwide return type, apply an
13213 E.4(18) check to the returned value.
13214 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13215 stream attributes of the designated type of an RACW, as they are not
13216 dispatching primitive operations.
13218 2007-06-06 Geert Bosch <bosch@adacore.com>
13220 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13222 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13224 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13225 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13227 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13229 2007-06-06 Javier Miranda <miranda@adacore.com>
13231 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13232 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13234 2007-06-06 Javier Miranda <miranda@adacore.com>
13236 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13237 deallocation of class-wide interface objects.
13238 (Expand_Dispatching_Constructor_Call): Take into account that if the
13239 result of the dispatching constructor is an interface type, the
13240 function returns a class-wide interface type; otherwise the returned
13241 object would be actual. The frontend previously accepted returning
13242 interface types because Expand_Interface_Actuals silently performed
13243 the management of the returned type "as if" it were a class-wide
13245 (Expand_Dispatching_Constructor_Call): Replace call to
13246 Make_DT_Access_Action by direct call to Make_Function_Call.
13248 2007-06-06 Robert Dewar <dewar@adacore.com>
13249 Ed Schonberg <schonberg@adacore.com>
13251 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13252 compute masking constant, since we now set Esize properly to the
13254 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13255 to match the alignment.
13256 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13257 packed arrays of 8 bits or less.
13259 * freeze.adb (Freeze_Entity): When freezing the formals of a
13260 subprogram, freeze the designated type of a parameter of an access type
13261 only if it is an access parameter.
13262 Increase size of C convention enumeration object
13263 (Freeze_Entity, array type case): Make sure Esize value is properly
13264 adjusted for the alignment if it is known.
13265 (Freeze_Entity, array type case): When checking bit packed arrays for
13266 the size being incorrect, check RM_Size, not Esize.
13267 (Freeze_Record_Type): Check for bad discriminated record convention
13268 (In_Exp_Body): Return true if the body is generated for a subprogram
13269 renaming, either an attribute renaming or a renaming as body.
13270 (Check_Itype): If the designated type of an anonymous access component
13271 is a non-protected subprogram type, indicate that it is frozen, to
13272 prevent out-of-scope freeze node at some subsequent call.
13273 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13274 only if the subprogram is neither imported nor exported, as well as the
13275 NCA descriptor class if the subprogram is exported.

13280 Gary Dismukes <dismukes@adacore.com>
13282 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13283 default initialization on an imported object, when there is no
13284 initialization call generated for it.
13285 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13288 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13289 Static_Elaboration_Desired.
13290 Remove pragma Thread_Body.
13291 Implement a new pragma No_Body
13292 Removes the Explicit_Overriding pragma
13293 Remove Optional_Overriding pragma
13294 (Prag): Deal with Universal_Aliasing.
13295 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13296 Pragma_CIL_Constructor): New names.
13298 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13299 uses the equivalent aggregate of a type must be treated as an implicit
13301 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13302 has none of the other categories.
13303 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13304 to apply Import to an object renaming declaration.
13306 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13307 from a C++ class should be declared as limited and that it will be
13308 considererd limited.
13309 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13310 should be declared as limited and that it will be considererd limited.
13311 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13312 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
13313 (Analyze_Pragma): Deal with Universal_Aliasing.
13314 (Sig_Flags): Likewise.
13315 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
13316 (Overflow_Checks_Unsuppressed): New flag.
13317 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
13318 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
13319 case of JVM or .NET targets, and compiling user code.
13320 Add debugging convenience routine rv
13322 2007-06-06 Robert Dewar <dewar@adacore.com>
13324 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
13325 are interface type.
13326 (Build_Elementary_Input_Call): For floating-point use right type in the
13327 absence of strange size or stream size clauses.
13328 (Build_Elementary_Write_Call): Same fix
13329 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
13330 set to value that does not match base type size.
13332 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13334 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13335 object of a limited type can be initialized with a call to a function
13336 that returns in place. If the limited type has unknown discriminants,
13337 and the underlying type is a constrained composite type, build an actual
13338 subtype from the function call, as is done for private types.
13339 (Side_Effect_Free): An expression that is the renaming of an object or
13340 whose prefix is the renaming of a object, is not side-effect free
13341 because it may be assigned through the renaming and its value must be
13342 captured in a temporary.
13343 (Has_Controlled_Coextensions): New routine.
13344 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13345 as is done for other limited types.
13346 (Non_Limited_Designated_Type): new predicate.
13347 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
13349 Remove all handling of with_type clauses.
13351 * par-ch10.adb: Remove all handling of with_type clauses.
13353 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
13354 checksum if the main source could not be parsed.
13355 (Loat_Unit): When processing a child unit, determine properly whether
13356 the parent unit is a renaming when the parent is itself a child unit.
13357 Remove handling of with_type clauses.
13359 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

13364 (Has_Init_Expression): New flag
13365 (Delay_Finalize_Attach): Remove because flag is obsolete.
13366 (Set_Delay_Finalize_Attach): Remove because flag is obsolete.

13374 not be parsed, because of preprocessing errors.
13376 * gnat1drv.adb (gnat1drv): Handle RE_Not_Available gracefully.
13377 (Gnat1drv): Exit with errors if the main source could not be parsed,
13378 because of preprocessing errors.

15203 to handle properly the anonymous access case.
15205 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
15206 for all access attributes, because overload resolution should work the
15207 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
15208 causes the error message for the ambiguous "X'Access = Y'Access" and
15209 "X'Unrestricted_Access = Y'Access" and so forth to match.
15210 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
15211 now that anonymous access to protected operations have their own kind.

15217 attempt to derive from a synchronized tagged type.
15218 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
15219 type, inherit the class-wide type already created, because it may
15220 already have been used in a self-referential anonymous access component.
15221 (Mentions_T): Recognize self-referential anonymous access components
15222 that use (a subtype of) the class-wide type of the enclosing type.
15223 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15224 Derived_Type for Prev formal on call to
15225 Check_Anonymous_Access_Components rather than Empty.
15226 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15227 a record extension in deciding whether to create a class-wide type,
15228 rather than just checking Tagged_Present.

15230 to stand-alone object declarations as well as component declarations.
15231 (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to
15232 prevent accidental overwriting when enclosing package appears in
15233 a limited_with_clause.
15234 (Array_Type_Declaration): If the component type is an anonymous access,
15235 the associated_node for the itype is the type declaration itself.

15241 to complete the decoration of synchronized interface types. Add also
15242 a call to Check_Abstract_Interfaces to verify the ARM rules.

15244 with abstract interfaces.
15245 (Analyze_Subtype_Indication): Resolve the range with the given subtype
15246 mark, rather than delaying the full resolution depending on context.

15272 Do not collect arguments if project is externally built.
15273 (Compile_Sources): Do nothing, not even check if the source is up to
15274 date, if its project is externally built.
15275 (Compile): When compiling a predefined source, add -gnatpg
15276 as the second switch, after -c.
15277 (Compile_Sources): Allow compilation of Annex J renames without -a
15278 (Is_In_Object_Directory): Check if the ALI file is in the object
15279 even if there is no project extension.
15280 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
15281 gnatbind if the ALI file effectively exists.
15282 (Initialize): Add the directory where gnatmake is invoked in front of
15283 the path if it is invoked from a bin directory, even without directory
15284 information, so that the correct GNAT tools will be used when spawned

15305 Unchecked_Deallocation only when Renamings_Included is True.
15307 * par.adb: Allow library units Calendar, Machine_Code,
15308 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15309 when -gnatg is not specified.
15310 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15311 there is no need to generate always a record_definition_node in case
15312 of synchronized interface types.
15313 (SIS_Entry_Active): Initialize global variable to False
15314 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

15339 (Convert_Aggr_In_Allocator): If the allocator is for an access
15340 discriminant and the type is controlled. do not place on a finalization
15341 list at this point. The proper list will be determined from the
15343 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
15344 initialize record controller if needed, before the components, to ensure
15345 that they are properly finalized.

15358 accessibility on class-wide allocators if the allocator occurs at the
15359 same scope level as the allocator's type. The check is guaranteed to
15360 succeed in that case, even when the expression originates from a
15361 parameter of the containing subprogram.
15362 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15363 under No_Dispatching_Calls restriction. During the semantic analysis
15364 we already notified such violation.
15365 (Tagged_Membership): Constant folding. There is no need to check
15366 the tag at run-time if the type of the right operand is non
15367 class-wide abstract.
15368 Replace call to Is_Ancestor by call to Is_Parent
15369 to support concurrent types with interface types.

15381 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
15382 initialize most the TSD components by means of an aggregate.
15383 Modify the declaration of the object containing the TSD
15384 because we now expand code that has a higher level of abstraction.
15385 The TSD has a discriminant containing the Inheritance Depth Level,
15386 value that is used in the membership test but also to fix the size
15387 of the table of ancestors.
15388 (Expand_Interface_Conversion): Insert function body at the closest place
15389 to the conversion expression, to prevent access-before-elaboration
15390 errors in the backend.

15392 compiling under restriction No_Dispatching_Calls plus code cleanup.
15393 Code reorganization plus removal of calls to Set_Num_Prim_Ops

15417 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15418 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_

15421 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

15426 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
15429 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15430 First (Parameter_Associations ()) with the call to First_Actual that
15431 returns an actual parameter expression for both named and positional
15434 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15435 check violation of restriction No_Dispatching_Calls.
15436 (Check_Controlling_Type): A formal of a tagged incomplete type is a
15437 controlling argument.

15440 First/Next_Component_Or_Discriminant
15441 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
15442 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15443 specify Any_Limited_Interface, and this functionality is already
15444 provided by the function Has_Abstract_Interfaces.
15445 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15446 support concurrent types implementing interfaces.
15447 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15448 specify kind Any_Limited_Interface, and this functionality is already
15449 provided by the function Has_Abstract_Interfaces.
15450 (Remove_Side_Effects): replace Controlled_Type by
15451 CW_Or_Controlled_Type whenever the issue is related to
15452 using or not the secondary stack.

15468 anonymous, use finalization list of enclosing dynamic scope.
15469 (Expand_N_Package_Declaration): For a library package declaration
15470 without a corresponding body, generate RACW subprogram bodies in the
15471 spec (just as we do for the task activation call).
15472 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15473 Is_Abstract_Type. Make sure these are called only when appropriate.
15474 Remove all code for DSP option

15491 Family_Size with 'Cap' set to true.
15492 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15493 a protected version of an operation declared in the private part of
15494 a protected object, because they may be invoked through a callback.
15495 (Set_Privals): If the type of a private component is an anonymous access
15496 type, do not create a new itype for each protected body.
15497 If the body of a protected operation creates
15498 controlled types (including allocators for class-widetypes), the
15499 body of the corresponding protected subprogram must include a

15506 for a possible overriding candidate.
15507 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15508 hold an actual parameter value since its initialization is separated

15518 Build_From_Any_Call.
15519 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15520 E_Constant, depending upon Variable formal.
15521 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15522 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15523 parameter that requires an extra constrained parameter, declare
15524 temporary for actual as a variable, not a constant.
15525 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15526 the unit being compiled is the one that contains the stub type.
15527 Change primitive operation name for the RACW associated with a RAS
15528 from Call to _Call so it cannot clash with any legal identifier.
15529 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15531 (Append_RACW_Bodies): New subprogram.
15532 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15533 Add_Receiving_Stubs_To_Declarations functions.
15534 When expanding a package body, this list correspond to the

15539 registering the receiving stubs at the end of the 'Stmts' list.
15540 (RCI_Package_Locator): Pass the new Version generic formal when
15541 instantiating a RCI_Locator package.
15542 (Build_From_Any_Function): To compute the High bound for an
15543 unconstrained array actual, we add the Low bound with the length.
15544 Thus we must convert the low bound and the length to an appropriate
15545 type before doing the sum.
15546 (Build_Subprogram_Receiving_Stubs, PolyORB):
15547 * Retrieve the extra formals parameters at the
15548 end of the parameter stream.
15549 * Use Move_Any_Value to write back out parameters
15550 after executing the request as it is more efficient
15551 than Copy_Any_Value.
15552 * Build the any containing Extra Formals with the
15553 appropriate typecode.
15554 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15555 empty Component_List.
15556 (Build_Actual_Object_Declaration): New subprogram. Build and insert into

15568 function with the first not implicit parent type.
15569 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15570 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15571 typecode from the Etype. Therefore we retrieve the correct typecode
15572 with a call to Get_Any_Type.
15573 (Copy_Specification): Do controlling formal type substitution based on
15574 Is_Controlling_Formal flag, instead of caller-provided object type.
15575 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15576 a RACW primitive operation, we might get a subprogram declaration for an
15577 ancestor of the RACW designated type (not for the designated type
15578 itself), in the case where this operation is inherited. In this case we
15579 have no easy means of determining the original tagged type for which
15580 the primitive was declared, so instead we now rely on
15581 Copy_Specification to use the Is_Controlling_Formal flag to determine
15582 which formals require type substitution.

15590 handler unsuitable as a target for a local raise statement.
15591 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15592 run-time subprogram CW_Membership by call to Build_CW_Membership.
15593 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15594 by a function call, a temporary must be created before expanding the
15595 Constructor_Call itself, to prevent out-of-order elaboration in the
15596 back-end when stack checking is enabled..

15673 (Check_Files): If no .ci files were specified for gnatstack we add all
15674 the .ci files belonging to the projects, including binder generated
15676 (Non_VMS_Usage): Document that gnatstack accept project file switches.
15677 (GNATCmd): Update the B_Start variable if we are in a VMS environment.
15678 Add gnatstack to the list of commands that use project file related
15679 switches, and get the single attribute Switches from the stack package

15727 This is needed as it is necessary to have access to both versions in the
15728 runtime for the form parameter encoding support.
15729 This set of patch add support for the encoding form parameter.
15730 (S2WS): Improve implementation to handle cases where the filename is not
15731 UTF-8 encoded. In this case we default to using the current code page
15732 for the conversion.
15734 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
15735 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

15779 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
15780 __gnat_adjust_context_for_raise.
15781 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
15782 implementation of floating point operations as native x86 targets.
15783 So the FPU should be initialized in the same way using finit. Fix
15784 floating point operations accuracy issues.
15785 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
15786 member in struct sigaction, so as to avoid warning for incompatible

15804 * lib-xref.ads, lib-xref.adb:
15805 Modify the loop that collects type references, to include interface
15806 types that the type implements. List each of these interfaces when
15807 building the entry for the type.
15808 (Generate_Definition): Initialize component Def and Typ of new entry
15809 in table Xrefs, to avoid to have these components unitialized.

15867 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
15868 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15869 there is no need to generate always a record_definition_node in case
15870 of synchronized interface types.
15871 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
15872 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
15873 illegal in Ada 95, in cases where it is legal. Change the warnings to
15874 errors in other cases. Don't give the error unless the "not null"
15875 parses properly. Correct the source position at which the error occurs.
15876 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
15877 P_Null_Exclusion, to suppress "not null" warnings.

15953 the default project path, initially done during elaboration of the
15955 If the prefix returned by Sdefault is null, get the prefix from a call
15956 to Executable_Prefix_Path.
15957 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
15960 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non

15963 (Record_Other_Sources): Idem.
15964 (Locate_Directory): Add the possibility to create automatically missing
15965 directories when Setup_Projects is True.

16013 Expand_Limited_With_Clause): Use a new copy of selector name in the
16014 call to Make_With_Clause. This fixes the tree structure for ASIS
16015 purposes. Nothing is changed in the compiler behaviour.
16016 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16017 a package renaming.
16018 (Install_Limited_With_Clauses): Do not install non-limited view when it
16019 is still incomplete.
16021 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16022 Gary Dismukes <dismukes@adacore.com>
16024 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16025 when capturing size information, instead of base type, which for a
16026 formal array type will be the unconstrained type.
16027 (Analyze_Formal_Object_Declaration): Add check for illegal default
16028 expressions for a formal in object of a limited type.
16029 (Instantiate_Object): Ditto.
16030 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16031 because they were defaulted in the formal package and no check applies
16033 (Check_Formal_Package_Instance): Extend conformance check to other
16034 discrete types beyond Integer.
16035 (Process_Default): Copy directly the unmatched formal. A generic copy
16036 has already been performed in Analyze_Formal_Package.
16037 (Analyze_Associations): If a formal subprogram has no match, check for
16038 partial parametrization before looking for a default, to prevent
16040 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16041 not set the instantiation environment before analyzing the actuals.
16042 Fixes regression on 8515-003 with implementation of AI-133.
16043 Set_Instance_Env checks whether the generic unit is a predefined
16044 unit, in which case the instance must be analyzed with the latest Ada
16045 mode. This setting must take place after analysis of the actuals,
16046 because the actuals must be analyzed and frozen in the Ada mode extant
16047 outside of the current instantiation.
16048 (Save_Env, Restore_Env): Preserve and restore the configuration
16049 parameters so that predefined units can be compiled in the proper Ada
16051 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,

16060 Gary Dismukes <dismukes@adacore.com>
16062 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16063 prefix type is a discriminated subtype of the type of the formal.
16064 (Analyze_Allocator): Collect all coextensions regardless of the context.
16065 Whether they can be allocated statically is determined in exp_ch4.
16066 (Analyze_Selected_Component): If the prefix is a limited view and the
16067 non-limited view is available, use the non-limited one.
16068 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16069 therefore illegal), suggest a qualified expression rather than a type
16070 conversion, because a type conversion would be illegal in this context.
16071 (Anayze_Allocator): Trace recursively all nested allocators so that all
16072 coextensions are on the corresponding list for the root. Do no mark
16073 coextensions if the root allocator is within a declaration for a stack-
16074 allocated object, because the access discriminants will be allocated on
16076 (Analyze_Call): Remove restriction on calls to limited functions for the
16077 cases of generic actuals for formal objects, defaults for formal objects
16078 and defaults for record components.
16079 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16080 element list. Their expansion is delayed until the enclosing allocator
16081 is processed and its finalization list constructed.
16082 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16083 for an operation with the given name among the primitive operations of
16084 the corresponding record type.
16085 (Analyze_Selected_Component): If the prefix is a task type that
16086 implements an interface, and there is no entry with the given name,
16087 check whether there is another primitive operation (e.g. a function)
16089 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16090 properly the indexing of a function call written in prefix form, where
16091 the function returns an array type, and all parameters of the function
16092 except the first have defaults.
16093 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16094 the original operands, rather than relocating them, for efficiency and
16095 to work properly when an operand is overloaded.
16096 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16097 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16098 (Analyze_Selected_Component): If the prefix is a private extension, only
16099 scan the visible components, not those of the full view.
16100 (Try_Primitive_Operation): If the operation is a procedure, collect all
16101 possible interpretations, as for a function, because in the presence of
16102 classwide parameters several primitive operations of the type can match

16132 identifier, and be special-cased in Check_Completion.
16133 Mark the full view of the designated type for the RACW associated with
16134 a RAS as Comes_From_Source to get proper view switching when installing
16135 private declarations.
16136 Provite a placeholder nested package body along with the nested spec
16137 to have a place for Append_RACW_Bodies to generate the calling stubs
16138 and stream attributes.

16167 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16168 dereference of a local object R created as a reference to another
16169 object O, use the access level of O.
16170 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16171 rather than local Same_Formal_Type, to check whether protected operation
16172 overrides an inherited one.
16173 (Same_Formal_Type): New predicate, used when matching signatures of
16174 overriding synchronized operations, to handle the case when a formal
16175 has a type that is a generic actual.
16176 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16177 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.

16190 (Is_Parent): New subprogram that determines whether E1 is a parent
16191 of E2. For a concurrent type its parent is the first element of its
16192 list of interface types; for other types this function provides the
16193 same result than Is_Ancestor.
16194 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16195 (Collect_Synchronized_Interfaces): Removed because the subprogram
16196 Collect_Abstract_Interfaces provides this functionality.
16197 (Collect_Abstract_Interfaces): Minor update to give support to
16198 concurrent types and thus avoid undesired code duplication.
16199 (Get_Subprogram_Entity): Handle entry calls.
16200 (May_Be_Lvalue): Include actuals that appear as in-out parameters in

16242 high bound is constant and the slice is empty. Tidy.
16243 (tree_transform, case N_Op_Not): Handle properly the case where the
16244 operation applies to a private type whose full view is a modular type.
16245 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16246 Address_Clause, use the associated Expression as the GNAT tree
16247 representing the choice value to ensure the corresponding GCC tree is
16248 of the proper kind.
16249 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16250 instead of just the operands, as the base GCC stabilize_reference does.
16251 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16252 requested; otherwise fail.
16253 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16513 (mainly static expression evaluation).
16514 Reword some continuation messages
16515 Add some \\ sequences to continuation messages
16516 (Resolve_Call): Refine infinite recursion case. The test has been

16530 during analysis, and use May_Be_Lvalue to distinguish read/write.
16531 (Valid_Array_Conversion): New procedure, abstracted from
16532 Valid_Conversion, to incorporate accessibility checks for arrays of
16533 anonymous access types.
16534 (Valid_Conversion): For a conversion to a numeric type occurring in an
16535 instance or inlined body, no need to check that the operand type is
16536 numeric, since this has been checked during analysis of the template.

17002 (__gnat_set_globals): Now a dummy function.
17003 (__gnat_handle_vms_condition): Feed adjust_context_for_raise with
17004 mechargs instead of sigargs, as the latter can be retrieved from the

17052 (Set_All_DT_Position): Hidden entities associated with abstract
17053 interface primitives are not taken into account in the check for

17065 alias of a predefined dispatching primitive.
17066 (Make_DT): If the ancestor of the type is a CPP_Class and we are
17067 compiling under full ABI compatibility mode we avoid the generation of
17068 calls to run-time services that fill the dispatch tables because under
17069 this mode we currently inherit the dispatch tables in the IP subprogram.
17070 (Write_DT): Emit an "is null" indication for a null procedure primitive.
17071 (Expand_Interface_Conversion): Use an address as the type of the formal
17072 of the internally built function that handles the case in which the

17123 we request a discriminal value only in case of discriminants.
17124 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17125 assignments where the target subtype is unconstrained and the target
17126 object is a parameter or dereference (other aliased cases are known

17242 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17243 are build-in-place function calls.
17244 (Replace_Self_Reference): New subsidiary of
17245 Make_OK_Assignment_Statement, to replace an access attribute that is a
17246 self-reference into an access to the appropriate component of the
17247 target object. Generalizes previous mechanism to handle self-references
17248 nested at any level.
17249 (Is_Self_Referential_Init): Remove, not needed.

17256 default initialization.
17257 (Make_OK_Assignment_Statement): If the expression is of the form
17258 Typ'Acc, where Acc is an access attribute, the expression comes from a
17259 default initialized self-referential component.
17260 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17261 that has been derived from several abstract interfaces we must also

17270 (Expand_Access_To_Protected_Op): If the context indicates that an access
17271 to a local operation may be transfered outside of the object, create an
17272 access to the wrapper operation that must be used in an external call.

17274 target, pass the Valid attribute applied to a floating-point prefix on

17290 subcomponent's enclosing variable is aliased with a constrained subtype.
17291 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17292 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17293 an aliased prefix must be known to be constrained in order to use True
17294 for the attribute value, and now it's possible for some aliased views
17295 to be unconstrained.

17310 otherwise we incorrectly register the tag of the interface in the final
17312 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17313 generate the wrapper if the parent primitive is abstract. This is
17314 required to report the correct error message.
17315 (Expand_N_Subtype_Indication): Do validity checks on range
17316 (Clean_Task_Names): If an initialization procedure includes a call to

17325 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17326 Object_Declaration to the call.
17327 (Freeze_Type): When the designated type of an RACW was not frozen at the
17328 point where the RACW was declared, validate the primitive operations
17329 with respect to E.2.2(14) when it finally is frozen.
17330 (Build_Initialization_Call,Expand_Record_Controller): Rename
17331 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17332 return-by-reference has no meaning in Ada 2005.

17334 to register tag of the immediate ancestor interfaces in the
17335 run-time structure.

17337 initialization of extension aggregates with abstract interfaces.
17338 (Build_Master_Renaming): Make public, for use by function declarations
17339 whose return type is an anonymous access type.
17340 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17341 Insert_List_Before_And_Analyze after the generation of the specs
17342 associated with null procedures.
17343 (Expand_Tagged_Root): Update documentation in its specification.
17344 (Init_Secondary_Tags): Update documentation.
17345 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17346 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17347 then generate code to inherit the contents of the dispatch table
17348 directly from the ancestor.
17349 (Expand_Record_Controller): Insert controller component after tags of
17350 implemented interfaces.
17351 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to

17355 declarations for overriding null primitives inherited from interfaces.
17356 (Is_Null_Interface_Procedure): New function in
17357 Make_Null_Procedure_Specs.
17358 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17359 immediate ancestor of a tagged type is an abstract interface type we
17360 must generate the specification of the predefined primitives associated
17361 with controlled types (because the dispatch table of the ancestor is
17362 null and hence these entries cannot be inherited). This is required to
17363 elaborate well the dispatch table.

17377 the maximum for type T.
17378 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17379 when the allocator is initialized by a build-in-place call, since the
17380 allocator is already rewritten as a reference to the function result,
17381 and this prevents an unwanted duplication of the function call.
17382 Add with and use of Exp_Ch6.
17383 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17384 is a call to build-in-place function and apply
17385 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17386 untagged designated types).
17387 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17388 optimization if source or target is biased.
17389 (Expand_N_Allocator): Add comments for case of an allocator within a

17407 in order to alleviate the upward compatibility introduced by AI-318.

17409 return object as a build-in-place result.

17411 within an extended return.
17412 (Enable_New_Return_Processing): Turn on the new processing of return

17417 (Expand_Simple_Function_Return): Ditto.
17418 (Expand_N_If_Statement): Handle new -gnatwt warning
17419 (Expand_N_Case_Statement): Handle new -gnatwt warning
17420 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17421 a protected object.
17422 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17423 validity checking of assignments to elementary record components.
17424 (Expand_N_Return_Statement): return Class Wide types on the secondary
17425 stack independantly of their controlled status since with HIE runtimes,
17426 class wide types are not potentially controlled anymore.
17428 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17431 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17432 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17433 it expects a block, procedure, or task. The return statement will get
17434 turned into a block, and Expand_Cleanup_Actions will happen then.

17437 Ed Schonberg <schonberg@adacore.com>
17438 Bob Duff <duff@adacore.com>
17439 Gary Dismukes <dismukes@adacore.com>
17441 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17443 (Expand_Inlined_Call): Tagged types are by-reference types, and
17444 therefore should be replaced by a renaming declaration in the expanded
17445 body, as is done for limited types.
17446 (Expand_Call): If this is a call to a function with dispatching access
17447 result, propagate tag from context.
17448 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17450 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17451 build-in-place when the right-hand side of an assignment is a
17452 build-in-place function call.
17453 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17454 of the explicit dereference of the allocator to the result subtype of
17455 the build-in-place function. This is needed to satisfy type checking
17456 in cases where the caller's return object is created by an allocator for
17457 a class-wide access type and the type named in the allocator is a
17459 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17460 conversion of the reference to the declared object to the result subtype
17461 of the build-in-place function. This is needed to satisfy type checking
17462 in cases where the declared object has a class-wide type. Also, in the
17463 class-wide case, change the type of the object entity to the specific
17464 result subtype of the function, to avoid passing a class-wide object
17465 without explicit initialization to the back end.
17466 (Register_Interface_DT_Entry): Moved outside the body of
17467 Freeze_Subprogram because this routine is now public; it is called from
17468 Check_Dispatching_Overriding to handle late overriding of abstract
17469 interface primitives.
17470 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17471 adding an implicit access actual on a call to a build-in-place function.
17472 (Expand_Actuals): Test for an actual parameter that is a call to a
17473 build-in-place function and apply
17474 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17475 (Is_Build_In_Place_Function): New function to determine whether an
17476 entity is a function whose calls should be handled as build-in-place.
17477 (Is_Build_In_Place_Function_Call): New function to determine whether an
17478 expression is a function call that should handled as build-in-place.
17479 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17480 calls to build-in-place functions as the initialization of an allocator.
17481 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17482 handling calls to build-in-place functions in contexts that do not
17483 involve init of a separate object (for example, actuals of subprogram
17485 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17486 handling calls to build-in-place functions as the initialization of an
17487 object declaration.
17488 (Detect_Infinite_Recursion): Add explicit parameter Process to
17489 instantiation of Traverse_Body to avoid unreferenced warning.
17490 (Check_Overriding_Inherited_Interfaces): Removed.
17491 (Register_Interface_DT_Entry): Code cleanup.
17492 (Register_Predefined_DT_Entry): Code cleanup.
17493 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17494 inlined statements if within a transient scope.
17495 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17496 formal parameters with occurrences of actuals in inlined body, establish
17497 visibility on the proper view of the actual's subtype for the body's
17499 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17500 compatibility mode and we have an imported CPP subprogram because
17501 for now we assume that imported CPP primitives correspond with
17502 objects whose constructor is in the CPP side (and therefore we
17503 don't need to generate code to register them in the dispatch table).
17504 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17505 aligned selected component.
17506 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17507 the actual of an in-mode parameter is a type conversion.
17508 (Expand_Actuals): If the call does not come from source and the actual
17509 is potentially misaligned, let gigi handle it rather than rejecting the
17510 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17511 Class Wide types as returning by reference independantly of their
17512 controlled status since with HIE runtimes class wide types are not
17513 potentially controlled anymore.
17515 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17517 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17518 references that are private components of the protected object.
17519 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
17520 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17521 instantiation to deal with warnings.
17522 (Initialize_Protection): If expression for priority is non-static, use
17523 System_Priority as its expected type, in case the expression has not
17526 2006-10-31 Robert Dewar <dewar@adacore.com>
17528 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17529 initialization of Homonym_Len.
17530 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17531 names from fully qualified name. Fixes problem of duplicate
17532 external names differing only in the presence of such a block name.
17534 2006-10-31 Thomas Quinot <quinot@adacore.com>
17535 Pablo Oliveira <oliveira@adacore.com>
17537 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17538 subprogram Ids, even if they are not yet assigned.
17539 (Build_Subprogram_Id): It is now this function that will take care of
17540 calling Assign_Subprogram_Ids if necessary.
17541 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17542 should be done only once they are assigned.
17543 (Build_From_Any_Function, case of tagged types): Add missing call to
17545 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17546 type for an RACW type.
17547 (Add_RACW_Features): When processing an RACW declaration for which the
17548 designated type is already frozen, enforce E.2.2(14) rules immediately.
17549 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17550 special reordering of controlling formals.
17552 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17553 associated stub type for an RACW type.
17555 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17557 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17558 fixed-point operations in an integer context, i.e. as operands of a
17559 conversion to an integer type, indicate that result must be rounded.
17561 2006-10-31 Robert Dewar <dewar@adacore.com>
17563 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17564 cases, pass the encoding method, since it is now required by the run
17567 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17568 assumption that Str'First = 1.
17569 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17570 it on to the Value_Wide_Wide_Character call.
17571 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17572 properly handles a string of the form quote-encoded_wide_char-quote.
17574 * s-wchcnv.adb: Minor reformatting
17576 2006-10-31 Javier Miranda <miranda@adacore.com>
17578 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17579 run-time membership test to ensure that the constructed object
17580 implements the target abstract interface.
17582 2006-10-31 Robert Dewar <dewar@adacore.com>
17584 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17585 Machine_Attribute pragma internally to implement the user pragma.
17586 Add processing for pragma Interface so that it is now completely
17587 equivalent to pragma Import.
17589 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17590 so that it can be applied to all entities, including record components
17591 and enumeration literals.
17592 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17593 priority ranges are correct, verify compatibility against task
17594 dispatching and locking policies, and if everything is correct an entry
17595 is added to the table containing priority specific dispatching entries
17596 for this compilation unit.
17597 (Delay_Config_Pragma_Analyze): Delay processing
17598 Priority_Specific_Dispatching pragmas because when processing the
17599 pragma we need to access run-time data, such as the range of
17600 System.Any_Priority.
17601 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17602 Allow pragma Unreferenced as a context item
17603 Add pragma Preelaborable_Initialization
17604 (Analyze_Pragma, case Interface): Interface is extended so that it is
17605 now syntactically and semantically equivalent to Import.
17606 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17607 insertion characters.
17608 Add handling for Pragma_Wide_Character_Encoding
17609 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17610 never supercedes a real restriction, and that a real restriction
17611 always supercedes a warning.
17612 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17616 Ed Schonberg <schonberg@adacore.com>
17617 Robert Dewar <dewar@adacore.com>
17619 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17620 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17621 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17623 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17624 type of the function containing a return statement, because the
17625 Return_Type field was removed. We now use the Return_Applies_To field.
17627 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17628 (Build_Task_Image_Decl): If procedure is not called from an
17629 initialization procedure, indicate that function that builds task name
17630 uses the sec. stack. Otherwise the enclosing initialization procedure
17631 will carry the indication.
17632 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17633 N_Object_Declaration instead.
17634 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17635 conditional dead code killed, and change implementation accordingly.
17636 (Insert_Actions): Add N_Return_Object_Declaration case.
17637 Correct comment to mention N_Extension_Aggregate node.
17638 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17639 attempts to save information for global variables which cannot be
17641 (Get_Current_Value_Condition): Handle conditions the other way round
17642 (constant on left). Also handle right operand of AND and AND THEN
17643 (Set_Current_Value_Condition): Corresponding changes
17644 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17645 (Get_Current_Value_Condition): Handle simple boolean operands
17646 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17647 (Get_Current_Value_Condition): If the variable reference is within an
17648 if-statement, does not appear in the list of then_statments, and does
17649 not come from source, treat it as being at unknown location.
17650 (Get_Current_Value_Condition): Enhance to allow while statements to be
17651 processed as well as if statements.
17652 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17654 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17655 of loop. This is safe now that we fixed Kill_Current_Values.
17656 (OK_To_Do_Constant_Replacement): Check whether current scope is
17657 Standard, before examining outer scopes.
17659 2006-10-31 Vincent Celier <celier@adacore.com>
17661 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17662 When True, apply VMS treatment to children of packages A, G, I and S.
17665 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17667 2006-10-31 Robert Dewar <dewar@adacore.com>
17668 Ed Schonberg <schonberg@adacore.com>
17670 * freeze.adb: Add handling of Last_Assignment field
17671 (Warn_Overlay): Supply missing continuation marks in error msgs
17672 (Freeze_Entity): Add check for Preelaborable_Initialization
17674 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17676 * g-expect.adb: Add Warnings (Off) to prevent new warning
17678 * lib-xref.adb: Add handling of Last_Assignment field
17679 (Generate_Reference): Centralize handling of pragma Obsolescent here
17680 (Generate_Reference): Accept an implicit reference generated for a
17681 default in an instance.
17682 (Generate_Reference): Accept a reference for a node that is not in the
17683 main unit, if it is the generic body corresponding to an subprogram
17686 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17688 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17690 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17692 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17693 use clauses, to avoid messages on packages used to qualify, and also
17694 to avoid messages from obsolescent units.
17695 (Warn_On_Useless_Assignments): Don't generate messages for imported
17696 and exported variables.
17697 (Warn_On_Useless_Assignments): New procedure
17698 (Output_Obsolescent_Entity_Warnings): New procedure
17699 (Check_Code_Statement): New procedure
17701 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
17702 Change name Is_Ada_2005 to Is_Ada_2005_Only
17703 (Last_Assignment): New field for useless assignment warning
17705 2006-10-31 Olivier Hainque <hainque@adacore.com>
17707 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17708 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17710 2006-10-31 Bob Duff <duff@adacore.com>
17711 Robert Dewar <dewar@adacore.com>
17712 Ed Schonberg <schonberg@adacore.com>
17714 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17715 Ada 95 mode, because it violates the new rules for AI-318.
17717 * g-awk.ads: Use overloaded subprograms in every case where we used to
17718 have a default of Current_Session. This makes the code closer to be
17719 correct for both Ada 95 and 2005.
17721 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17722 code, relying on the fact that the compiler generates a warning
17723 instead of an error in -gnatg mode.
17725 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17726 E_Return_Statement entity kind.
17727 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17729 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17730 report an error if the reserved word abstract has been previously found.
17731 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17733 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17734 parenthesized range attribute usage
17735 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17737 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17738 in the syntax for extended_return_statement. This is not in the latest
17739 RM, but the ARG is expected to issue an AI allowing this.
17740 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17741 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17742 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17743 P_Return_Statement): Parse the new syntax for extended_return_statement.
17745 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17746 Output_End_Missing): Add error-recovery code for the new
17747 extended_return_statement syntax; that is, the new E_Return entry on
17750 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17751 limited to nonlimited, because otherwise we violate the new Ada 2005
17752 rules about returning limited types in function Create_AST_Handler in
17755 * sem.adb (Analyze): Add cases for new node kinds
17756 N_Extended_Return_Statement and N_Return_Object_Declaration.
17758 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17759 type is in the same category as type of context before applying check,
17760 to prevent anomalies in instantiations.
17761 (Resolve_Aggregate): Remove test for limited components in aggregates.
17762 It's unnecessary in Ada 95, because if it has limited components, then
17763 it must be limited. It's wrong in Ada 2005, because limited aggregates
17765 (Resolve_Record_Aggregate): Move check for limited types later, because
17766 OK_For_Limited_Init requires its argument to have been resolved.
17767 (Get_Value): When copying the component default expression for a
17768 defaulted association in an aggregate, use the sloc of the aggregate
17769 and not that of the original expression, to prevent spurious
17770 elaboration errors, when the expression includes function calls.
17771 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17772 were missing. We also didn't handle qualified expressions. Now also
17773 allow function calls. Use new common routine OK_For_Limited_Init.
17774 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17775 with space can upper case letter).
17777 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17778 Has_Static_Discriminants flag
17779 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17780 type with discriminants.
17781 (Process_Range_Expr_In_Decl): Do validity checks on range
17782 (Build_Discriminant_Constraints): Use updated form of
17783 Denotes_Discriminant.
17784 (Process_Subtype): If the subtype is a private subtype whose full view
17785 is a concurrent subtype, introduce an itype reference to prevent scope
17787 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17788 Record_Type_Declaration): The functionality of the subprograms
17789 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17790 is now performed by a single routine.
17791 (Build_Derived_Record_Type): If the type definition includes an explicit
17792 indication of limitedness, then the type must be marked as limited here
17793 to ensure that any access discriminants will not be treated as having
17794 a local anonymous access type.
17795 (Check_Abstract_Overriding): Issue a detailed error message when an
17796 abstract subprogram was not overridden due to incorrect mode of its
17798 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17799 synchronized private extension declarations. Verify that the ancestor is
17800 a limited or synchronized interface or in the generic case, the ancestor
17801 is a tagged limited type or synchronized interface and all progenitors
17802 are either limited or synchronized interfaces.
17803 Derived_Type_Declaration): Check for presence of private extension when
17804 dealing with synchronized formal derived types.
17805 Process_Full_View): Enchance the check done on the usage of "limited" by
17806 testing whether the private view is synchronized.
17807 Verify that a synchronized private view is completed by a protected or
17809 (OK_For_Limited_Init_In_05): New function.
17810 (Analyze_Object_Declaration): Move check for limited types later,
17811 because OK_For_Limited_Init requires its argument to have been resolved.
17812 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17813 in order to alleviate the upward compatibility introduced by AI-318.
17814 (Constrain_Corresponding_Record): If the constraint is for a component
17815 subtype, mark the itype as frozen, to avoid out-of-scope references to
17816 discriminants in the back-end.
17817 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17818 this subprogram against wrong sources.
17819 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17820 discriminant of limited type completed with a protected type, when the
17821 discriminant is used to constrain a private component of the type, and
17822 expansion is disabled.
17823 (Find_Type_Of_Object): Do not treat a return subtype that is an
17824 anonymous subtype as a local_anonymous_type, because its accessibility
17825 level is the return type of the enclosing function.
17826 (Check_Initialization): In -gnatg mode, turn the error "cannot
17827 initialize entities of limited type" into a warning.
17828 (OK_For_Limited_Init): Return true for generated nodes, since it
17829 sometimes violates the legality rules.
17830 (Make_Incomplete_Declaration): If the type for which an incomplete
17831 declaration is created happens to be the currently visible entity,
17832 preserve the homonym chain when removing it from visibility.
17833 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17834 inherited subprograms.
17835 (Access_Definition): If this is an access to function that is the return
17836 type of an access_to_function definition, context is a type declaration
17837 and the scope of the anonymous type is the current one.
17838 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17839 incomplete subtype to the set of private dependents of the original
17841 (Constrain_Discriminated_Type): Emit an error message whenever an
17842 incomplete subtype is being constrained.
17843 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17844 corresponding subtype of the full view of the original incomplete type.
17845 (Check_Incomplete): Properly detect invalid usage of incomplete types
17848 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
17850 * g-catiio.ads, g-catiio.adb (Value): New function.
17851 Given an input String, try and parse a valid Time value.
17853 2006-10-31 Vincent Celier <celier@adacore.com>
17855 * g-debpoo.adb (Is_Valid): Correctly compute Offset using
17856 Integer_Address arithmetic, as in Set_Valid.
17858 2006-10-31 Arnaud Charlet <charlet@adacore.com>
17859 Robert Dewar <dewar@adacore.com>
17861 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
17862 handling executable extension manually and duplicating code.
17864 * make.adb: Implement new -S switch
17865 (Gnatmake): Use new function Osint.Executable_Name instead
17866 of handling executable extension manually.
17868 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
17869 is specified, the executable name ends with this suffix.
17870 Take advantage of Osint.Executable_Name instead of duplicating code.

17874 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
17876 (Get_Target_Parameters): Set Executable_Extension_On_Target if

17881 2006-10-31 Vincent Celier <celier@adacore.com>
17883 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17884 call it with -static-libgcc, as there are some platforms, such as
17885 Darwin, where one of these two switches is compulsory to link.
17887 2006-10-31 Vincent Celier <celier@adacore.com>
17889 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17890 instead of ADA_PROJECT_PATH, for the project path.
17891 (Gnatls): When displaying the project path directories, use host dir
17894 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17895 names in the project path, as absolute paths may correspond to
17896 multi-valued VMS logical names.
17898 2006-10-31 Vincent Celier <celier@adacore.com>
17900 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
17901 absolute path name.
17902 (Locate_Regular_File): Ditto
17903 (Change_Dir): Remove, no longer used

17927 2006-10-31 Robert Dewar <dewar@adacore.com>
17929 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
17931 (Layout_Variant_Record): Retrieve the discriminants from the entity
17932 rather than from the type definition, because in the case of a full
17933 type for a private type we need to take the discriminants from the
17935 (Layout_Component_List): When applying the Max operator to variants with
17936 a nonstatic size, check whether either operand is static and scale that
17937 operand from bits to storage units before applying Max.
17938 (Layout_Type): In VMS, if a C-convention access type has no explicit
17939 size clause (and does not inherit one in the case of a derived type),
17940 then the size is reset to 32 from 64.
17942 2006-10-31 Vincent Celier <celier@adacore.com>
17944 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
17945 its file has already been loaded, according to the unit being loaded,
17946 not to the current value of Multiple_Unit_Index.
17948 2006-10-31 Thomas Quinot <quinot@adacore.com>
17949 Eric Botcazou <ebotcazou@adacore.com>
17950 Arnaud Charlet <charlet@adacore.com>
17952 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
17953 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
17955 (a-except.o): Pass it to the compiler.
17956 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.

17964 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
17966 * Make-lang.in: Remove all references to gt-ada-decl.h.
17967 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler

17976 * mlib-utl.adb (Initialized): Remove, no longer used
17977 (Initialize): Remove, no longer used
17978 (Ar): If Ar_Exec is null, get the location of the archive builder and,
17979 if there is one, the archive indexer. Fail if the archive builder cannot
17981 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
17984 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17986 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
17987 Process_Body_Clauses): If the context of a body includes a use clause
17988 for P.Q then a with_clause for P in the same body is not redundant,
17989 even if the spec also has a with_clause on P.
17990 Add missing continuation mark to error msg
17991 (Build_Limited_Views): A limited view of a type is tagged if its
17992 declaration includes a record extension.
17993 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
17994 node, even if the subunit has errors. This avoids malfunction by
17995 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
17996 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
17997 generation of obsolescent messages for with statements (cannot do
17998 this too early, or we cannot implement avoiding the messages in the
17999 case of obsolescent units withing obsolescent units).
18000 (Install_Siblings): If the with_clause is on a remote descendant of
18001 an ancestor of the current compilation unit, find whether there is
18002 a sibling child unit that is immediately visible.
18003 (Remove_Private_With_Clauses): New procedure, invoked after completing
18004 the analysis of the private part of a nested package, to remove from
18005 visibility the private with_clauses of the enclosing package
18007 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18008 now centralized in Generate_Reference.
18009 (Install_Limited_Context_Clauses): Remove superfluous error
18010 message associated with unlimited view visible through use
18011 and renamings. In addition, at the point in which the error
18012 is reported, we add the backslash to the text of the error
18013 to ensure that it is reported as a single error message.
18014 Use new // insertion for some continuation messages
18015 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18016 to create implicit with_clause for parent unit mentioned in original
18017 limited_with_clause.
18018 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18019 unit is a child unit. For ASIS queries.
18020 (Analyze_Subunit): If the subunit appears within a child unit, make all
18021 ancestor child units directly visible again.

18036 a formal object declaration with an access definition or a subtype mark
18037 with a null exclusion.
18038 (P_Generic_Association): Handle association with box, and others_choice
18039 with box, to support Ada 2005 partially parametrized formal packages.
18041 2006-10-31 Robert Dewar <dewar@adacore.com>
18042 Javier Miranda <miranda@adacore.com>
18044 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18045 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18046 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18047 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18048 private extensions.
18049 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18050 to P_Interface_Type_Definition.
18051 (P_Interface_Type_Definition): Addition of one formal to report an error
18052 if the reserved word abstract has been previously found.
18053 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18054 object renaming declaration with an access definition or subtype mark
18055 with a possible null exclusion.

18074 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18077 2006-10-31 Vincent Celier <celier@adacore.com>
18079 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18080 on VMS, change "__" to '.' before checking the name.
18081 (Record_Ada_Source): Always add the source file name in the list of
18082 of sources, even if it is not the first time, as it is for another
18084 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18085 dot, instead of replacing only the first '_'.
18087 * prj-part.adb (Parse): Convert project file path to canonical form
18089 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18090 extended, the project id of the project extending it is recorded in its
18091 data, even when it has already been processed as an imported project.
18093 2006-10-31 Robert Dewar <dewar@adacore.com>
18095 * repinfo.adb (List_Entities): Don't list entities from renaming
18098 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18099 Robert Dewar <dewar@adacore.com>
18101 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18102 only a restriction warning is active for the given restriction. This is
18103 desirable because we do not want to modify code in the case where only
18105 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18106 causes overriding of real restrictions.
18107 Take advantage of new No_Restrictions constant.
18109 * raise.h: (__gnat_set_globals): Change profile.
18111 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18113 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18116 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18117 Move all the entities in obsolete package System.PolyORB_Interface to
18118 System.Partition_Interface.
18119 (RE_Storage_Size): New function in System.Tasking.

18132 Thomas Quinot <quinot@adacore.com>
18133 Javier Miranda <miranda@adacore.com>
18134 Gary Dismukes <dismukes@adacore.com>
18136 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18137 properly an attempt to apply Unchecked_Access to a protected operation.
18138 (OK_Self_Reference): New subprogram to check the legality of an access
18139 attribute whose prefix is the type of an enclosing aggregate.
18140 Generalizes previous mechanism to handle attribute references nested
18141 arbitrarily deep within the aggregate.
18142 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18143 can appear in an aggregate if this is a default-initialized aggregate
18144 for a self-referential type.
18145 (Resolve_Attribute, case Access): Ditto.
18146 Add support for new implementation defined attribute Stub_Type.
18147 (Eval_Attribute, case Attribute_Stub_Type): New case.
18148 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18149 (Stream_Attribute_Available): Implement using new subprogram from
18150 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18151 Has_Specified_Stream_Attribute flag.
18152 Disallow Storage_Size and Storage_Pool for access to subprogram
18153 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18154 access types of return subtypes in extended return statements. Remove
18155 accessibility checks on anonymous access types when Unchecked_Access is
18157 (Analyze_Attribute): Add support for the use of 'Class to convert
18158 a class-wide interface to a tagged type.
18159 Add support for the attribute Priority.
18160 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18161 whether the designated type is discriminated with a constrained partial
18162 view and require static matching in that case.
18163 Add local variable Des_Btyp. The Designated_Type
18164 of an access to incomplete subtype is either its non-limited view if
18165 coming from a limited with or its etype if regular incomplete subtype.
18167 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18168 Fix predicate to identify and allow cases of (expander-generated)
18169 references to tag of designated object of a RACW.
18170 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18171 non-static, and therefore cannot appear as a primary in a preelaborable
18173 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18174 Has_Read_Write_Attributes.
18175 (Has_Read_Write_Attributes): Reimplement in termes of
18176 Has_Stream_Attribute_Definition.
18177 (Missing_Read_Write_Attributes): When checking component types in a
18178 record, unconditionally call Missing_Read_Write_Attributes recursively
18179 (remove guard checking for Is_Record_Type / Is_Access_Type).
18181 2006-10-31 Robert Dewar <dewar@adacore.com>
18183 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18184 useless assignments here and conditionalize it on absence of exception
18186 (Analyze_Exception_Handlers): Small code reorganization of error
18187 detection code, for new handling of formal packages.
18189 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18190 Hristian Kirtchev <kirtchev@adacore.com>
18192 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18193 that has been constant-folded, preserve information of original tree,
18195 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18196 generated private extension declaration if the formal derived type is
18197 synchronized. Carry synchronized present over to the generated private
18199 (Validate_Derived_Type_Instance): Ensure that the actual of a
18200 synchronized formal derived type is a synchronized tagged type.
18201 (Instantiate_Formal_Package): When creating the instantiation used to
18202 validate the actual package of a formal declared without a box, check
18203 whether the formal itself depends on a prior actual.
18204 (Instantiate_Formal_Subprogram): Create new entities for the defining
18205 identifiers of the formals in the renaming declaration, for ASIS use.
18206 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18207 a renaming declaration or a subtype declaration for an actual in an
18208 instance, capture location information of declaration in generic, for
18210 (Instantiate_Formal_Package): Add comments on needed additional tests.
18211 AI-317 (partial parametrization) is fully implemented.
18212 (Validate_Private_Type_Instance): Add check for actual which
18213 must have preelaborable initialization
18214 Use new // insertion for some continuation messages
18215 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18216 Default_Expression. Add type retrieval when the declaration has an
18217 access definition. Update premature usage of incomplete type check.
18218 (Check_Access_Definition): New subsidiary routine. Check whether the
18219 current compilation version is Ada 05 and the supplied node has an
18221 (Instantiate object): Alphabetize local variables. Handle the creation
18222 of new renaming declarations with respect to the kind of definition
18223 used - either an access definition or a subtype mark. Guard against
18224 unnecessary error message in the context of anonymous access types after
18225 they have been resolved. Add check for required null exclusion in a
18226 formal object declaration.
18227 (Switch_View): A private subtype of a non-private type needs to be
18228 switched (the base type can have been switched without its private
18229 dependents because of the last branch of Check_Private_View.
18230 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18232 (Instantiate_Type): Emit an error message whenever a class-wide type of
18233 a tagged incomplete type is used as a generic actual.
18234 (Find_Actual_Type): Extend routine to handle a component type in a child
18235 unit that is imported from a formal package in a parent.
18236 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18237 agree on constrainedness, rather than checking against ultimate ancestor
18238 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18239 generic body, for navigation purposes.
18241 2006-10-31 Robert Dewar <dewar@adacore.com>
18242 Thomas Quinot <quinot@adacore.com>
18244 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18246 (New_Stream_Subprogram): When processing an attribute definition clause
18247 for a stream-oriented subprogram, record an entity node occurring at
18248 the point of clause to use for checking the visibility of the clause,
18249 as defined by 8.3(23) as amended by AI-195.
18250 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18251 New_Stream_Function and New_Stream_Procedure.
18252 (New_Stream_Function, New_Stream_Procedure): Removed.
18253 (Analyze_Attribute_Definition_Clause, case Address): Check new
18254 Alignment_Check check
18256 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18257 Javier Miranda <miranda@adacore.com>
18258 Robert Dewar <dewar@adacore.com>
18260 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18261 generate the same errors compiling under -gnatc.
18262 (Try_Object_Operation): If no candidate interpretation succeeds, but
18263 there is at least one primitive operation with the right name, report
18264 error in call rather than on a malformed selected component.
18265 (Analyze_Selected_Component): If the prefix is an incomplete type from
18266 a limited view, and the full view is available, use the full view to
18267 determine whether this is a prefixed call to a primitive operation.
18268 (Operator_Check): Verify that a candidate interpretation is a binary
18269 operation before checking the type of its second formal.
18270 (Analyze_Call): Add additional warnings for function call contexts not
18272 (Analyze_Allocator): Move the check for "initialization not allowed for
18273 limited types" after analyzing the expression. This is necessary,
18274 because OK_For_Limited_Init looks at the structure of the expression.
18275 Before analysis, we don't necessarily know what sort of expression it
18276 is. For example, we don't know whether F(X) is a function call or an
18277 indexed component; the former is legal in Ada 2005; the latter is not.
18278 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18279 were missing. We also didn't handle qualified expressions. Now also
18280 allow function calls. Use new common routine OK_For_Limited_Init.
18281 (Analyze_Type_Conversion): Do not perform some legality checks in an
18282 instance, because the error message will be redundant or spurious.
18283 (Analyze_Overloaded_Selected_Component): Do not do style check when
18284 setting an entity, since we do not know it is the right entity yet.
18285 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18286 (Analyze_Overloaded_Selected_Component): Same change
18287 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18288 since regular incomplete subtypes are transformed into corresponding
18289 subtypes of their full views.
18290 (Complete_Object_Operation): Treat name of transformed subprogram call
18291 as coming from source, for browsing purposes.
18292 (Try_Primitive_Operation): If formal is an access parameter, compare
18293 with base type of object to determine whether it is a primitive
18295 (Operator_Check): If no interpretation of the operator matches, check
18296 whether a use clause on any candidate might make the operation legal.
18297 (Try_Class_Wide_Operation): Check whether the first parameter is an
18298 access type whose designated type is class-wide.

18305 warn on infinite loops.
18306 Add \\ to some continuation messages
18307 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18308 (Process_Bounds): If the bounds are integer literals that result from
18309 constant-folding, and they carry a user-defined type, preserve that type
18310 rather than treating this as an integer range.
18311 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18312 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18313 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18314 left hand side of assignment.
18315 (Analyze_Assignment): Add suport to manage assigments to the attribute
18316 priority of a protected object.
18317 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18318 not just identifiers.
18319 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18320 or AND THEN for possible tracking.
18321 (Analyze_Iteration_Scheme): Check for setting Current_Value for the

18326 Bob Duff <duff@adacore.com>
18328 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18329 procedure cannot be a protected operation (it is a basic_declaration,
18330 not a subprogram_declaration).
18331 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18332 Subp. Add logic for entry processing.
18333 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18334 Determine whether an entry or subprogram of a protected or task type
18335 override an inherited primitive of an implemented interface.
18336 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18337 Update the actual used in calls to Check_Overriding_Indicator.
18338 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18339 generate the proper reference to the parent unit, for cross-reference.
18340 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18342 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18343 (Add_Extra_Formal): Revise procedure to allow passing in associated
18344 entity, scope, and name suffix, and handle setting of the new
18345 Extra_Formals field.
18346 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18347 pass new parameters. Add support for adding the new extra access formal
18348 for functions whose calls are treated as build-in-place.
18349 (Analyze_A_Return_Statement): Correct casing in error message.
18350 Move Pop_Scope to after Analyze_Function_Return, because an extended
18351 return statement really is a full-fledged scope. Otherwise, visibility
18352 doesn't work right. Correct use of "\" for continuation messages.
18353 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18354 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18355 the node doesn't get properly marked as analyzed.
18356 (Analyze_Subprogram_Body): If subprogram is a function that returns
18357 an anonymous access type that denotes a task, build a Master Entity
18359 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18360 proper usage of null exclusion in a result definition.
18361 (Process_Formals): Code cleanup and new error message.
18362 (Process_Formals): Detect incorrect application of null exclusion to
18364 (Conforming_Types): Handle conformance between [sub]types and itypes
18365 generated for entities that have null exclusions applied to them.
18366 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18367 base type is an access subtype. This case arrises with null exclusions.
18368 (New_Overloaded_Entity): Do not remove the overriden entity from the
18369 homonym chain if it corresponds with an abstract interface primitive.
18370 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18371 call to the synthesized predicate Is_Incomplete_Type.
18372 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18374 (Analyze_Subprogram_Declaration): Check that abstract interface
18375 primitives are abstract or null.
18376 (Analyze_Subprogram_Specification): Remove previous check for abstract
18377 interfaces because it was not complete.
18378 (Has_Interface_Formals): Removed.

18381 Javier Miranda <miranda@adacore.com>
18383 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18384 of Analyze_Package_Body, to create Itype references for anonymous
18385 access types created in the package declaration, whose designated types
18386 may have only a limited view.
18387 (Analyze_Package_Specification): For the private part of a nested
18388 package, install private_with_clauses of enclosing compilation unit if
18389 we are in its visible part.
18390 (Declare_Inherited_Private_Subprograms): Complete barrier
18391 to ensure that the primitive operation has an alias to some parent
18392 primitive. This is now required because, after the changes done for the
18393 implementation of abstract interfaces, the contents of the list of
18394 primitives has entities whose alias attribute references entities of
18395 such list of primitives.
18396 (Analyze_Package_Specification): Simplify code that handles parent units
18397 of instances and formal packages.
18398 (Uninstall_Declarations): Check the convention consistency among
18399 primitive overriding operations of a tagged record type.

18408 expected and found set right)
18409 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated

18411 (Use_One_Package): Do not take into account the internal entities of
18412 abstract interfaces during the analysis of entities that are marked
18413 as potentially use-visible.
18414 (Find_Type): Handle the case of an attribute reference for
18415 implementation defined attribute Stub_Type (simply let the analysis of
18416 the attribute reference rewrite it).
18417 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18418 type that appears in a Use_Type clause.
18419 (Analyze_Object_Renaming): Add support for renaming of the Priority
18421 (Find_Type): In Ada 2005, a task type can be used within its own body,
18422 when it appears in an access definition.
18423 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18424 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18425 in a formal object declaration or in a subtype declaration.
18426 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18427 (Check_Null_Exclusion): New local routine to
18428 Analyze_Subprogram_Renaming. Check whether the formals and return
18429 profile of a renamed subprogram have required null exclusions when
18430 their counterparts of the renaming already impose them.
18431 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18432 Determine whether an entity is inside a generic scope.
18433 (In_Open_Scope): First pass of documentation update.
18434 (Find_Expanded_Name): Add support for shadow entities associated with
18435 limited withed packages. This is required to handle nested packages.
18436 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18437 that makes a renaming of a limited withed package illegal.
18439 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18440 Ed Schonberg <schonberg@adacore.com>
18442 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18443 Check_Overriding_Indicator.
18444 (Analyze_Task_Definition): Ditto.
18445 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18446 (Check_Overriding_Indicator): To find overridden interface operation,
18447 examine only homonyms that have an explicit subprogram declaration, not
18448 inherited operations created by an unrelated type derivation.
18449 (Check_Overriding_Indicator): When checking for the presence of "null"
18450 in a procedure, ensure that the queried node is a procedure
18452 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18453 type when the formal is an access to variable.
18454 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18455 (Analyze_Task_Type): Same addition
18456 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
18457 provide navigation capabilities for entries.

18460 Ed Schonberg <schonberg@adacore.com>
18461 Javier Miranda <miranda@adacore.com>
18462 Gary Dismukes <dismukes@adacore.com>
18464 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18465 inherited from an interface ancestor by another interface in the
18466 context of an instance as 'late'.
18467 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18468 of a call to a function that dispatches on access result.
18469 (Check_Dispatching_Operation): In case of late overriding of a primitive
18470 that covers abstract interface subprograms we register it in all the
18471 secondary dispatch tables associated with abstract interfaces.
18472 (Check_Dispatching_Call): Add check that a dispatching call is not made
18473 to a function with a controlling result of a limited type. This is a
18474 current implementation restriction.
18475 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18476 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18477 argument is an interface type that is a generic formal.
18478 (Is_Interface_Subprogram): Removed.
18479 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18480 operation, check the formals to handle the case in which it is
18481 associated with an abstract interface type.
18483 2006-10-31 Robert Dewar <dewar@adacore.com>
18484 Ed Schonberg <schonberg@adacore.com>

18498 Hristian Kirtchev <kirtchev@adacore.com>
18499 Javier Miranda <miranda@adacore.com>
18501 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18502 subprogram type to provide better diagnostics in case of ambiguity.
18503 (Covers): Handle coverage of formal and actual anonymous access types in
18504 the context of generic instantiation.
18505 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18506 abstract interface types; this is required to handle concurrent types
18507 with discriminants and abstract interface types.

18521 Add missing continuation marks in error msgs
18522 (Unqualify): New function for removing zero or more levels of
18523 qualification from an expression. There are numerous places where this
18524 ought to be used, but we currently only deal properly with zero or one
18526 (In_Instance); The analysis of the actuals in the instantiation of a
18527 child unit is not within an instantiation, even though the parent
18528 instance is on the scope stack.
18529 (Safe_To_Capture_Value): Exclude the case of variables that are
18531 (Check_Obsolescent): Removed
18532 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

18534 object in an assignment.
18535 (Get_Subprogram_Entity): New function
18536 (Known_To_Be_Assigned): New function

18545 Change Is_Lvalue to May_Be_Lvalue
18546 (May_Be_Lvalue): Extensive additional code to deal with subprogram
18547 arguments (IN parameters are not Lvalues, IN OUT parameters are).
18548 (Safe_To_Capture_Value): Extend functionality so it can be used for
18549 the current value condition case.
18550 (Has_Compatible_Alignment): New function
18551 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
18552 objects to handle the Ada 2005 case, where aliasedness no longer implies
18553 that the object is constrained. In particular, for dereferenced names,
18554 the designated object must be assumed to be unconstrained.
18555 (Kill_Current_Values): Properly deal with the case where we encounter
18556 a loop in the scope chain.

18601 (Procedure_To_Call): Move to a different place to make room in
18602 N_Extended_Return_Statement.
18603 (Return_Type): Removed this field to make room in return statements
18605 (Return_Statement_Entity): New field in return statements, in part to
18606 replace Return_Type, and in part to support the fact that return
18607 statements are now pushed on the scope stack during semantic analysis.
18608 (Return_Object_Declarations): New field to support extended return
18610 (N_Extended_Return_Statement): New node for extended_return_statement
18612 (N_Return_Object_Declaration): New node for part of
18613 extended_return_statement nonterminal. Needed because all the necessary
18614 fields won't fit in N_Extended_Return_Statement.

18634 print null exclusion twice in the case of an access definition,
18635 Implement new -gnatL switch

18637 N_Object_Declaration instead. Implement the case for
18638 N_Extended_Return_Statement. Alphabetize the cases.
18639 Add cases for new nodes N_Extended_Return_Statement and
18640 N_Return_Object_Declaration. The code is not yet written.

18694 2006-10-31 Olivier Hainque <hainque@adacore.com>
18696 * s-stchop.ads: make this unit preelaborate. This is desirable in

18698 is itself preelaborate.
18700 * s-stchop-vxworks.adb (Set_Stack_Info, Task_Descriptor type): Add
18701 Td_Events component.

18786 * a-rttiev.ads, a-rttiev.adb:
18787 This is a significant redesign primarily for the sake of automatic
18788 timer task termination but also to fix a design flaw.
18789 Therefore we are now using an RTS lock, instead of a protected
18790 object, to provide mutual exclusion to the queue of pending events
18791 and the type Timing_Event is no longer a protected type.

19581 with small changes.
19584 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
19585 variable with the expression being built, only its inner field.

19639 other basic tools. The full version that includes the Ada 2005 stuff
19640 is in separate files a-except-2005.ads/adb. The reason is that we do
19641 not want to cause bootstrap problems with compilers not recognizing
19643 Add exception reason code PE_Implicit_Return

19966 positive. Also add checks against invalid values, and support for kb,
19967 mb. Ditto for -D switch.
19969 2006-02-13 Robert Dewar <dewar@adacore.com>
19970 Serguei Rybin <rybin@adacore.com>
19972 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
19973 save/restore routines.
19974 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

19976 Since we are changing the tree format anyway, also get rid of the
19977 junk obsolete Immediate_Errors flag.
19978 (Tree_Read): Change the way of reading Tree_Version_String - now we
19979 read the version string from the tree even if its length is not the
19980 same as the length of the version string computed from Gnatvsn.

20043 are of equal length and have the same start and end values.
20044 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20045 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20046 aggregate when it is part of an object declaration.
20047 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20048 constrains discriminants of its parent, add explicitly the discriminant
20049 constraints of the ancestor by retrieving them from the

20052 2006-02-13 Robert Dewar <dewar@adacore.com>
20054 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20055 attribute Mechanism_Code is applied to renamed subprogram, modify
20056 prefix to point to base subprogram.
20057 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20059 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20060 renamed subprograms so that the front-end must replace the prefix
20063 2006-02-13 Javier Miranda <miranda@adacore.com>
20064 Gary Dismukes <dismukes@adacore.com>
20066 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20067 availability of RE_Interface_Tag.

20069 (Freeze_Record_Type): Do not generate the tables associated with
20070 timed and conditional dispatching calls through synchronized
20071 interfaces if compiling under No_Dispatching_Calls restriction.
20072 When compiling for Ada 2005, for a nonabstract
20073 type with a null extension, call Make_Controlling_Function_Wrappers
20074 and insert the wrapper function declarations and bodies (the latter
20075 being appended as freeze actions).
20076 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20077 predefined primitives associated with timed and conditional
20078 dispatching calls through synchronized interfaces if we are
20079 compiling under No_Dispatching_Calls.
20080 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20081 service is available before generating a call.
20082 (Make_Controlling_Function_Wrappers): New procedure.
20083 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20084 access-to-limited-interfaces because they can be used to reference
20085 tasks that implement such limited interface.
20086 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20087 procedure spec and body of the Offset_To_Top function that is generated
20088 when the parent of a type with discriminants has secondary dispatch
20090 (Init_Secondary_Tags): Handle the case in which the parent of the type
20091 containing secondary dispatch tables has discriminants to generate the
20092 correct arguments to call Set_Offset_To_Top.
20093 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20095 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20096 Add Wide_[Wide_]Expanded_Name.
20097 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20098 the same functionality of Get_Prim_Op_Address but applied to predefined
20099 primitive operations because the pointers to the predefined primitives
20100 are now saved in a separate table.
20101 (Parent_Size): Modified to get access to the separate table of primitive
20102 operations or the parent type.
20103 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20104 functionality of Set_Prim_Op_Address but applied to predefined primitive
20106 (Set_Signature): New subprogram used to store the signature of a DT.
20107 (Displace): If the Offset_To_Top value is not static then call the
20108 function generated by the expander to get such value; otherwise use
20109 the value stored in the table of interfaces.
20110 (Offset_To_Top): The type of the actual has been changed to Address to
20111 give the correct support to tagged types with discriminants. In this
20112 case this value is stored just immediately after the tag field.
20113 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20114 offset_to_top value is static and hence pass this value to the run-time
20115 to store it in the table of interfaces, or else if this value is dynamic
20116 and then pass to the run-time the address of a function that is
20117 generated by the expander to provide this value for each object of the
20120 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20121 (Default_Prim_Op_Count): New entity

20130 Make_Adjust_Call done for a newly-allocated object.
20132 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20133 in a subprogram are wrapped in a cleanup block, indicate that the
20134 subprogram contains an inner block with an exception handler.
20135 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20136 Adjust call is for a newly-allocated object. In that case we must not
20137 assume that the finalization list chain pointers are correct (since they
20138 come from a bit-for-bit copy of the original object's pointers) so if
20139 the attach level would otherwise be zero (no change), we set it to 4
20140 instead to cause the pointers to be reset to null.
20142 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20143 reset chain pointers to null.
20145 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20147 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20148 string, and the context requires a loop for the assignment (e.g.
20149 because the left-hand side is packed), generate a unique name for the
20150 temporary that holds the string, to prevent spurious name clashes.
20152 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20153 Javier Miranda <miranda@adacore.com>
20154 Robert Dewar <dewar@adacore.com>
20155 Gary Dismukes <dismukes@adacore.com>
20157 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20158 return unconstrained arrays.
20160 (Expand_Call): An indirect call through an access parameter of a
20161 protected operation is not a protected call.
20162 Add circuit to raise CE in Ada 2005 mode following call
20163 to Raise_Exception.
20164 (Register_DT_Entry): Do nothing if
20165 the run-time does not give support to abstract interfaces.
20166 (Freeze_Subprogram): In case of dispatching operations, do not generate
20167 code to register the operation in the dispatch table if the source
20168 is compiled with No_Dispatching_Calls.
20169 (Register_Predefined_DT_Entry): Generate code that calls the new
20170 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20171 Set_Prim_Op_Address.
20173 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20174 on array assignments if the right-hand side is a function call that has
20175 been inlined. Check is performed on the assignment in the block.
20176 (Process_Bounds): If bounds and range are overloaded, apply preference
20177 rule for root operations to disambiguate, and diagnose true ambiguity.
20178 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20179 a tag-indeterminate right-hand side even when Expander_Active is True.
20180 Needed to ensure that dispatching calls to T'Input are allowed and
20181 get the tag of the target class-wide object.
20183 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20184 an inherited primitive operation that already overrides several
20185 abstract interface primitives. For transitivity, the new entity must
20186 also override all the abstract interface primitives covered by the
20187 inherited overriden primitive.
20188 Emit warning if new entity differs from homograph in same scope only in
20189 that one has an access parameter and the other one has a parameter of
20190 a general access type with the same designated type, at the same
20191 position in the signature.
20192 (Make_Inequality_Operator): Use source locations of parameters and
20193 subtype marks from corresponding equality operator when creating the
20194 tree structure for the implicit declaration of "/=". This does not
20195 change anything in behaviour except that the decoration of the
20196 components of the subtree created for "/=" allows ASIS to get the
20197 string images of the corresponding identifiers.
20198 (Analyze_Return_Statement): Remove '!' in warning message.
20199 (Check_Statement_Sequence): Likewise.
20200 (Analyze_Subprogram_Body): For an access parameter whose designated type
20201 is an incomplete type imported through a limited_with clause, use the
20202 type of the corresponding formal in the body.
20203 (Check_Returns): Implicit return in No_Return procedure now raises
20204 Program_Error with a compile time warning, instead of beging illegal.
20205 (Has_Single_Return): Function returning unconstrained type cannot be
20206 inlined if expression in unique return statement is not an identifier.
20207 (Build_Body_To_Inline): It is possible to inline a function call that
20208 returns an unconstrained type if all return statements in the function
20209 return the same local variable. Subsidiary procedure Has_Single_Return
20210 verifies that the body conforms to this restriction.
20212 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20213 same type, and one of them is of an anonymous access type, convert
20214 the other operand to it, so that this is a valid binary operation for
20216 (Resolve_Type_Conversion): Handle subtypes of protected types and
20217 task types when accessing to the corresponding record type.
20218 (Resolve_Allocator): Add '\' in 2-line warning message.
20219 Remove '!' in warning message.
20220 (Resolve_Call): Add '\' in 2-line warning message.
20221 (Valid_Conversion): Likewise.
20222 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20223 resulting type may be an access type with an implicit dereference.
20224 Obtain the proper component from the designated type.
20225 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20226 given by an expanded name with prefix Standard, when the operands are
20227 of an anonymous access type.
20228 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20229 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20230 prefix of the expression is not of an incomplete type. Allows full
20231 diagnoses of all semantic errors.
20232 (Resolve_Actuals): If the actual is an allocator whose directly
20233 designated type is a class-wide interface we build an anonymous
20234 access type to use it as the type of the allocator. Later, when
20235 the subprogram call is expanded, if the interface has a secondary
20236 dispatch table the expander will add a type conversion to force
20237 the displacement of the pointer.
20238 (Resolve_Call): If a function that returns an unconstrained type is
20239 marked Inlined_Always and inlined, the call will be inlined and does
20240 not require the creation of a transient scope.
20241 (Check_Direct_Boolean_Op): Removed
20242 (Resolve_Comparison_Op): Remove call to above
20243 (Resolve_Equality_Op): Remove call to above
20244 (Resolve_Logical_Op): Inline above, since this is only call.
20245 (Valid_Conversion): Handle properly conversions between arrays of
20246 convertible anonymous access types.
20249 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20250 the literal in an unchecked conversion, because GCC 4.x needs a static
20251 value for a string bound.
20253 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20254 Hristian Kirtchev <kirtchev@adacore.com>
20256 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20257 components of the corresponding record, take into account component
20258 definitions that are access definitions.
20259 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20260 procedure is not considered a dispatching call and will be expanded
20263 2006-02-13 Javier Miranda <miranda@adacore.com>
20265 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20266 controlling argument of the dispatching call is an abstract interface
20267 class-wide type then we use it directly.
20268 Check No_Dispatching_Calls restriction.
20269 (Default_Prim_Op_Position): Remove the code that looks for the last
20270 entity in the list of aliased subprograms. This code was wrong in
20272 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20273 when the source is compiled with the No_Dispatching_Calls restriction.
20274 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20275 if we are compiling with restriction No_Dispatching_Calls.
20276 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20277 subprograms if we are compiling under No_Dispatching_Calls restriction.
20278 (Make_DT): Generate a dispatch table with a single dummy entry if
20279 we are compiling with the No_Dispatching_Calls restriction. In
20280 addition, in this case we don't generate code that calls to the
20281 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20282 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20283 of this subprogram if compiling with the No_Dispatching_Calls
20285 (Expand_Type_Conversion): Instead of using the actual parameter,
20286 the argument passed as parameter to the conversion function was
20287 erroneously referenced by the expander.
20288 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20289 Set_Predefined_Primitive_Op_Address and Set_Signature.
20290 (Expand_Dispatching_Call): Generate call to
20291 Get_Predefined_Prim_Op_Address for predefined primitives.
20292 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20293 predefined primitives.
20294 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20295 primitives we reserve one dummy entry to ensure that the tag does not
20296 point to some memory that is associated with some other object. In
20297 addition, remove all the old code that generated the assignments
20298 associated with the signature of the dispatch table and replace them
20299 by a call to the new subprogram Set_Signature.
20300 (Set_All_DT_Position): Change the algorithm because now we have a
20301 separate dispatch table associated with predefined primitive operations.
20302 (Expand_Interface_Conversion): In case of non-static offset_to_top
20303 add explicit dereference to get access to the object after the call
20304 to displace the pointer to the object.
20305 (Expand_Interface_Thunk): Modify the generation of the actual used
20306 in the calls to the run-time function Offset_To_Top to fulfil its
20308 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.

20312 * exp_dist.adb (Copy_Specification): For access parameters, copy
20313 Null_Exclusion flag, which will have been set for stream subprograms
20316 2006-02-13 Pascal Obry <obry@adacore.com>
20318 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20319 previous implementation was using the C runtime spawnve routine but
20320 the corresponding wait was using directly the Win32 API. This was
20321 causing some times a lock when waiting for an event using
20322 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20323 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20324 API fixes this problem.
20326 2006-02-13 Robert Dewar <dewar@adacore.com>
20328 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20335 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
20336 array reference that is an explicit dereference, mark the converted
20337 (packed) array reference as analyzed to prevent a forthcoming
20338 reanalysis from resetting its type to the original (non-packed) array
20341 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20342 Javier Miranda <miranda@adacore.com>
20343 Eric Botcazou <ebotcazou@adacore.com>
20345 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20346 Is_Predefined_Primitive_Operation): When
20347 searching for the predefined equality operator, verify that operands
20348 have the same type.
20349 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20350 for the last entity in the list of aliased subprograms. This code
20351 was wrong in case of renamings.
20352 (Set_Renamed_Subprogram): New procedure
20353 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20354 Exp_Type constant computed when entering this subprogram.
20355 (Known_Null): New function
20356 (OK_To_Do_Constant_Replacement): New function
20357 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20358 (Side_Effect_Free): An attribute reference 'Input is not free of
20359 side effect, unlike other attributes that are functions. (from code
20361 (Remove_Side_Effects): Expressions that involve packed arrays or records
20362 are copied at the point of reference, and therefore must be marked as
20363 renamings of objects.
20364 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20365 not a dispatching operation.
20368 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20369 elementary types in all cases.
20371 2006-02-13 Javier Miranda <miranda@adacore.com>

20374 task types when accessing to the corresponding record type.
20375 Remove '!' in warning message.
20377 2006-02-13 Olivier Hainque <hainque@adacore.com>
20379 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20380 to avoid useless and space inefficient overalignments on targets where
20381 Max_Alignment is larger than 16.
20383 2006-02-13 Pascal Obry <obry@adacore.com>
20385 * g-catiio.adb (Sec_Number): New type used to compute the number of
20386 seconds since 1-1-1970.
20387 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20388 negative numbers (years, months...) it is better to have a Natural here.
20390 (Image) [Number]: Change parameter from Long_Integer to Number.
20391 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20392 overflow for dates past year 2038.
20394 2006-02-13 Matthew Heaney <heaney@adacore.com>
20396 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20399 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20401 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20403 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20404 finalization can occur normally.
20406 2006-02-13 Vincent Celier <celier@adacore.com>
20408 * gnatcmd.adb (Rules_Switches): New table
20409 (Add_To_Rules_Switches): New procedure
20410 (GNATCmd): For command CHECK, put all options following "-rules" in the
20411 Rules_Switches table. Append these -rules switches after the -cargs
20414 2006-02-13 Robert Dewar <dewar@adacore.com>
20416 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20417 These two cases were generating incorrect output, and if this unit
20418 was built with checks on, generated a discriminant mismatch constraint
20421 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20422 Robert Dewar <dewar@adacore.com>
20424 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20425 view is an array type, indicate the component type as well, for
20426 navigation purposes.
20427 (Generate_Reference): Don't consider array ref on LHS to be a case
20428 of violating pragma Unreferenced.
20429 Do not give Ada 2005 warning except on real reference.
20431 2006-02-13 Vincent Celier <celier@adacore.com>
20433 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20434 main source, add switch -mdebug-main=_ada_ so that the executable can
20435 be debugged by the standard VMS debugger.
20436 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20437 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20438 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20439 of the last source, as the binding and linking phases are never
20441 Set all executable obsolete when rebuilding a library.
20443 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20446 2006-02-13 Javier Miranda <miranda@adacore.com>
20449 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20450 code to improve the error message reported when the program has
20451 declarations of abstract interface types and it is not compiled with
20452 the -gnat05 switch.
20453 (P_Access_Definition): Reorganize the code to improve the error
20454 message reported when the new Ada 2005 syntax for anonymous
20455 access types is used and the program is not compiled with the

20472 the standard naming data.
20474 2006-02-13 Vincent Celier <celier@adacore.com>
20476 * prj.ads (Error_Warning): New enumeration type
20478 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20479 unknown, use the location of the project to report the error.
20480 (When_No_Sources): New global variable
20481 (Report_No_Ada_Sources): New procedure
20482 (Check): New parameter When_No_Sources. Set value of global variable
20484 (Find_Sources): Call Report_No_Ada_Sources when appropriate
20485 (Get_Sources_From_File): Ditto
20486 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20489 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20490 Call Prj.Proc.Process with parameter When_No_Sources.
20492 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20493 Call Recursive_Check with parameter When_No_Sources.
20494 (Recursive_Check): New parameter When_No_Sources. Call itself and
20495 Prj.Nmsc.Check with parameter When_No_Sources.
20496 (Process): New parameter When_No_Sources. Call Check with parameter
20498 (Copy_Package_Declarations): New procedure to copy renamed parameters
20499 and setting the location of the declared attributes to the location
20500 of the renamed package.

20508 When removing nodes (attributes Source_Dirs, Source_Files,
20509 Source_List_File and package Naming), save the comments and attach the
20510 saved comments to the newly created nodes.
20511 Do not add a with clause for the naming package if one already exists.

20519 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
20520 aliased entities to look for the overriden abstract interface
20522 (Is_Interface_Subprogram): Complete documentation.
20523 (Check_Dispatching_Operation): Do not generate code to register the
20524 operation in the dispatch table if the source is compiled with
20525 restriction No_Dispatching_Calls.
20526 (Override_Dispatching_Operation): Check for illegal attempt to override
20527 No_Return procedure with procedure that is not No_Return
20528 (Check_Dispatching_Call): Suppress the check for an abstract operation
20529 when the original node of an actual is a tag-indeterminate attribute
20530 call, since the attribute, which must be 'Input, can never be abstract.
20531 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20532 call to the Input attribute (even when rewritten).
20533 (Propagate_Tag): Augment comment to indicate the possibility of a call
20534 to an Input attribute.
20536 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20537 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
20539 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
20540 No_Wide_Characters is no longer partition-wide
20541 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
20544 2006-02-13 Douglas Rupp <rupp@adacore.com>
20546 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20548 2006-02-13 Javier Miranda <miranda@adacore.com>
20550 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20551 handles default-initialized components to keep separate the management
20552 of this feature but also avoid the unrequired resolution and
20553 expansion of components that do not have partially initialized
20555 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20556 (Check_Bounds): Likewise.
20557 (Check_Length): Likewise.
20559 2006-02-13 Javier Miranda <miranda@adacore.com>
20560 Ed Schonberg <schonberg@adacore.com>
20562 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20563 abstract interface type call analyze_and_resolve to expand the type
20564 conversion into the corresponding displacement of the
20565 reference to the base of the object.
20566 (Eval_Attribute, case Width): For systems where IEEE extended precision
20567 is supported, the maximum exponent occupies 4 decimal digits.
20568 (Accessibility_Message): Add '\' in 2-line warning message.
20569 (Resolve_Attribute): Likewise.
20570 (case Attribute_Access): Significantly revise checks
20571 for illegal access-to-subprogram Access attributes to properly enforce
20572 the rules of 3.10.2(32/2).
20573 Diagnose use of current instance with an illegal attribute.
20575 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20577 (Enclosing_Generic_Unit): New function to return a node's innermost
20578 enclosing generic declaration node.
20579 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20580 (Type_Access_Level): The accessibility level of anonymous acccess types
20581 associated with discriminants is that of the current instance of the
20582 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20583 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20584 (Kill_Current_Values_For_Entity): New function
20585 (Enter_Name): Change formal type to Entity_Id
20587 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20588 Ed Schonberg <schonberg@adacore.com>
20589 Gary Dismukes <dismukes@adacore.com>
20591 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20592 Analyze_Compilation_Unit.
20593 Detect and warn on redundant with clauses detected in a package spec
20594 and/or body when -gnatwr is used.

20598 with_clause so that cross-reference information or warning messages on
20599 unused packages can be properly generated
20600 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20601 has Error_Posted set. Prevent infinite loops in illegal programs.
20602 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20603 to the point of the error test requiring the current unit to be private.
20604 This ensures that private with clauses are not exempted from the basic
20605 checking for being a descendant of the same library unit parent as a
20606 withed private descendant unit.
20607 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20608 handle private with clauses properly, as well as to account for cases
20609 where the withed unit is a public descendant of a private ancestor
20610 (in which case the current unit must be a descendant of the private
20611 ancestor's parent). The spec comments were updated accordingly. Also,
20612 the old error message in this subprogram was replaced with error
20613 messages that mirror the errors tested and reported by
20614 Check_Private_Child_Unit.
20615 Parameter and variable names improved for readability.
20616 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20617 private as the precondition for calling
20618 Check_Private_Limited_Withed_Unit since that subprogram has been
20619 revised to test public units as well as private units.

20624 Javier Miranda <miranda@adacore.com>
20626 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20627 that Scope_Stack.First = 1.
20628 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20629 were not always properly handled previously.
20630 (Formal_Entity): Complete rewrite, to handle properly some complex case
20631 with multiple levels of parametrization by formal packages.
20632 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20633 to the corresponding derived type declaration for proper semantics.
20635 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20636 (Check_Component): Enforce restriction on components of
20637 unchecked_unions: a component in a variant cannot contain tasks or
20639 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20641 Add pragma Ada_2005 (synonym for Ada_05)
20642 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20643 were not always properly handled previously.
20644 Document that pragma Propagate_Exceptions has no effect
20645 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20646 (Set_Convention_From_Pragma): Check that if a convention is
20647 specified for a dispatching operation, then it must be
20648 consistent with the existing convention for the operation.
20649 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20650 longer required to specify an vtable-ptr component in the record. For
20651 compatibility reasons we leave the support for the previous definition.
20652 (Analyze_Pragma, case No_Return): Allow multiple arguments
20654 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20655 non-overrideen inherited operation with a controlling result as
20656 illegal only its implicit declaration comes from the derived type
20657 declaration of its result's type.
20658 (Check_Possible_Deferred_Completion): Relocate the object definition
20659 node of the subtype indication of a deferred constant completion rather
20660 than directly analyzing it. The analysis of the generated subtype will
20661 correctly decorate the GNAT tree.
20662 (Record_Type_Declaration): Check whether this is a declaration for a
20663 limited derived record before analyzing components.
20664 (Analyze_Component_Declaration): Diagnose record types not explicitly
20665 declared limited when a component has a limited type.
20666 (Build_Derived_Record_Type): Code reorganization to check if some of
20667 the inherited subprograms of a tagged type cover interface primitives.
20668 This check was missing in case of a full-type associated with a private
20670 (Constant_Redeclaration): Check that the subtypes of the partial and the
20671 full view of a constrained deferred constant statically match.
20672 (Mentions_T): A reference to the current type in an anonymous access
20673 component declaration must be an entity name.
20674 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20675 class_wide type to refer to full type, not to the incomplete one.
20676 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20677 available. Required to give support to the certified run-time.
20678 (Analyze_Component_Declaration): In case of anonymous access components
20679 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20680 (Process_Discriminants): For an access discriminant, use the
20681 discriminant specification as the associated_node_for_itype, to
20682 simplify accessibility checks.

20687 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20688 abstract interpretations on an operator, remove interpretations that
20689 yield Address or a type derived from it, if one of the operands is an
20691 (Try_Object_Operation.Try_Primitive_Operation,
20692 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20693 location when creating the new reference to a primitive or class-wide
20694 operation as a part of rewriting a subprogram call.
20695 (Try_Primitive_Operations): If context requires a function, collect all
20696 interpretations after the first match, because there may be primitive
20697 operations of the same type with the same profile and different return
20698 types. From code reading.
20699 (Try_Primitive_Operation): Use the node kind to choose the proper
20700 operation when a function and a procedure have the same parameter
20702 (Complete_Object_Operation): If formal is an access parameter and prefix
20703 is an object, rewrite as an Access reference, to match signature of
20704 primitive operation.
20705 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20706 by an expanded name with prefix Standard, when the operands are of an
20707 anonymous access type.
20708 (Remove_Abstract_Operations): If the operation is abstract because it is
20709 inherited by a user-defined type derived from Address, remove it as
20710 well from the set of candidate interpretations of an overloaded node.
20711 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20714 2006-02-13 Bob Duff <duff@adacore.com>
20716 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20717 redundant use clauses.
20718 In particular, if the scope of two use clauses overlaps, but one is not
20719 entirely included in the other, we should not warn. This can happen
20720 with nested packages.
20721 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20722 reported errors. The bug was reported when the compiler was built
20723 with assertions enabled.
20724 (Find_Type): If the node is a 'Class reference and the prefix is a
20725 synchronized type without a corresponding record, return the type
20728 2006-02-13 Javier Miranda <miranda@adacore.com>
20730 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20731 if this is the full-declaration associated with a private declaration
20732 that implement interfaces, then the private type declaration must be
20734 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20735 as aliased. The use of the 'access attribute is not available for such
20736 object (for this purpose the object should be explicitly marked as
20737 aliased, but being an anonymous type this is not possible).
20739 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20740 Robert Dewar <dewar@adacore.com>
20742 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20743 compilation unit is an elaboration scope.
20744 (Add_Task_Proc): Add '\' in 2-line warning message.
20745 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20747 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20748 Javier Miranda <miranda@adacore.com>
20750 * sem_type.adb (Write_Overloads): Improve display of candidate
20752 (Add_One_Interp): Do not add to the list of interpretations aliased
20753 entities corresponding with an abstract interface type that is an
20754 immediate ancestor of a tagged type; otherwise we have a dummy
20755 conflict between this entity and the aliased entity.
20756 (Disambiguate): The predefined equality on universal_access is not
20757 usable if there is a user-defined equality with the proper signature,
20758 declared in the same declarative part as the designated type.
20759 (Find_Unique_Type): The universal_access equality operator defined under
20760 AI-230 does not cover pool specific access types.
20761 (Covers): If one of the types is a generic actual subtype, check whether
20762 it matches the partial view of the other type.
20764 2006-02-13 Thomas Quinot <quinot@adacore.com>
20766 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20767 line. This is necessary to allow In_Extended_Main_Unit to provide
20768 correct results for itypes while writing out expanded source.
20769 (Close_File): No need to update the source_index_table here since it's
20770 now done for each line.
20772 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20773 Robert Dewar <dewar@adacore.com>
20775 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20776 preserve the source unit where the itype is declared, and prevent a
20778 (Note_Implicit_Run_Time_Call): New procedure
20779 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
20782 * sprint.ads: Document use of $ for implicit run time routine call
20784 2006-02-13 Quentin Ochem <ochem@adacore.com>
20786 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
20789 2006-02-13 Bob Duff <duff@adacore.com>
20791 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20792 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20793 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20794 raise Constraint_Error.
20796 * s-vallli.adb (Scan_Long_Long_Integer): Call
20797 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20798 do not scan leading blanks and sign twice.
20799 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20800 raise Constraint_Error.
20802 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20803 Scan_Long_Long_Unsigned): Split out most of the processing from
20804 Scan_Long_Long_Unsigned out into
20805 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20806 This prevents scanning leading blanks and sign twice.
20807 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20810 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20811 out most of the processing from Scan_Unsigned out into
20812 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20813 This prevents scanning leading blanks and sign twice.
20815 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20816 use with Modular'Value attribute.
20817 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
20820 2006-02-13 Robert Dewar <dewar@adacore.com>
20822 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
20824 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>
20826 * tracebak.c (PPC AIX/Darwin): Define FORCE_CALL to 1.
20827 (PPC VxWorks): Likewise.
20828 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
20829 (forced_callee): Make non-inlinable and non-pure.
20830 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

21012 Quentin Ochem <ochem@adacore.com>
21013 Florian Villoing <villoing@adacore.com>
21015 * a-taster.ads, a-taster.adb: New files.
21017 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21018 link to the version that does nothing. This way the task termination
21019 routine is not executed twice for the environment task when finishing
21020 because of an unhandled exception.
21022 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21023 handler because of an unhandled exception.
21025 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
21026 System.Tasking.Utilities instead of that in System.Tasking.Stages.
21028 * s-finimp.adb (initialization code): Modify the soft link for the
21029 finalization of the global list instead of Adafinal.
21031 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21032 non-tasking version of the soft link for task termination. We do
21033 nothing since if we are using the non-tasking version it
21034 means that the task termination functionality is not used.
21035 (Null_Finalize_Global_List): Add this null version for the procedure
21036 in charge of finalizing the global list for controlled objects.
21037 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21038 instead for handling run-time termination in a more flexible way.
21039 (Adafinal_NT): This new procedure will take care of finalizing the
21040 global list for controlled objects if needed, but no tasking
21043 * s-tarest.adb (Task_Lock): Do not try to lock again the
21044 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21045 some run-time operations.
21046 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21047 until all nested locks have been released.
21048 (Task_Wrapper): Call the fall-back task termination handler. It
21049 applies to all tasks but the environment task.
21050 (Finalize_Global_Tasks): Add the call for the task termination
21051 procedure for the environment task.
21052 (Task_Wrapper): suppress warnings around declaration of
21053 Secondary_Stack_Address.
21055 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21056 moved to the Common_ATCB record.
21057 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21058 Common_ATCB record.
21059 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21060 Common_ATCB record.
21062 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21063 Fall_Back_Handler, and Specific_Handler.
21065 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21066 defined in Ada.Task_Termination, to avoid circular dependencies.
21067 (Termination_Handler): Redefine this type here, alredy defined in
21068 Ada.Task_Termination, for avoiding circular dependencies.
21069 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21070 for storing task termination handlers. In addition,
21071 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21072 Common_ATCB because it is used by both the regular and the restricted
21074 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21075 Common_ATCB because it is used by both the regular and the restricted
21077 (Common_ATCB): Added a dynamic task analyzer field.
21079 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21080 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21081 (Task_Wrapper): Call the task termination handler. It applies to all
21082 tasks but the environment task.
21083 (Finalize_Global_Tasks): Call the task termination procedure for the
21084 environment task. The call to Finalize_Global_List is now performed
21085 using the soft links mechanism.
21086 (Task_Wrapper): added dynamic stack analysis.
21088 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21089 potentially blocking operations has been moved from
21090 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21091 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21092 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21093 this run-time check.
21095 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21096 of task termination procedure.
21097 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21098 link for the task termination procedure.
21100 * bindusg.adb: (Bindusg): Added documentation for -u option.
21102 * bindgen.adb (Get_Main_Ada) Added handling of dynamic stack analysis.

21110 * opt.ads: Added flags used by dynamic stack measurement.
21111 (Max_Line_Length): Remove (not used anymore)
21113 * s-io.ads, s-io.adb (Standard_Error): new subprogram
21114 (Standart_Output): new subprogram
21115 (Set_Output): new subprogram
21116 (Put): now uses the value of Current_Out to know if the output has to be
21117 send to stderr or stdout.
21119 * s-stausa.ads: Complete implementation.
21121 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
21123 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
21124 list of Ada 05 files.
21125 (GNAT Library Units): Add AltiVec files.
21127 * g-allein.ads, g-alleve.adb, g-alleve.ads, g-altcon.adb,
21128 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
21129 g-alvety.ads, g-alvevi.ads: New files providing altivec API.
21131 2005-12-09 Nicolas Setton <setton@adacore.com>
21133 * adaint.c (__gnat_locate_regular_file): Return immediately if
21134 file_name is empty.
21136 2005-12-09 Javier Miranda <miranda@adacore.com>
21137 Hristian Kirtchev <kirtchev@adacore.com>
21139 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21140 to the specification because the frontend generates code that uses this
21142 (Set_Interface_Table): Add missing assertion.
21143 Update documentation describing the run-time structure.
21144 (Displace): New subprogram that displaces the pointer to the object
21145 to reference one of its secondary dispatch tables.
21146 (IW_Membership): Modified to use the new table of interfaces.
21147 (Inherit_TSD): Modified to use the new table of interfaces.
21148 (Register_Interface_Tag): Use the additional formal to fill the
21149 contents of the new table of interfaces.
21150 (Set_Interface_Table): New subprogram that stores in the TSD the
21151 pointer to the table of interfaces.
21152 (Set_Offset_To_Top): Use the additional formal to save copy of
21153 the offset value in the table of interfaces.
21154 Update structure of GNAT Primary and Secondary dispatch table diagram.
21155 Add comment section on GNAT dispatch table prologue.
21156 (Offset_To_Signature): Update the constant value of the Signature field.
21157 (Dispatch_Table): Update comment on hidden fields in the prologue.
21158 (Get_Entry_Index, Get_Prim_Op_Kind, Get_Offset_Index, OSD,
21159 Set_Entry_Index, Set_Offset_Index, Set_Prim_Op_Kind, SSD, TSD): Change
21160 the type of formal parameter T to Tag, introduce additional assertions.
21161 (Get_Num_Prim_Ops, Set_Num_Prim_Ops): Remove an unnecessary type
21163 (Get_Tagged_Kind, Set_Tagged_Kind): New bodies.
21165 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21166 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21167 record component containing the tag of the secondary dispatch table we
21168 have to use the Offset_To_Top run-time function to get this information;
21169 otherwise if the pointer to the base of the object has been displace
21170 we get a wrong value if we use the 'position attribute.
21172 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21173 all the calls to Expand_Interface_Thunk.
21174 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

21367 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
21368 base type to create anonymous subtype, because entity may be a locally
21369 declared subtype or generic actual.
21370 (Find_Interface): New subprogram that given a tagged type and one of its
21371 component associated with the secondary table of an abstract interface
21372 type, return the entity associated with such abstract interface type.

21375 conversion cannot be handled at compile time. In this case we pass this
21376 information to the expander to generate the appropriate code.

21414 legal within a protected type that implements an interface.
21415 (Collect_Interfaces): Do not add to the list the interfaces that
21416 are implemented by the ancestors.
21417 (Derived_Type_Declaration): If the parent of the full-view is an
21418 interface perform a transformation of the tree to ensure that it has
21419 the same parent than the partial-view. This simplifies the job of the
21420 expander in order to generate the correct object layout, and it is
21421 needed because the list of interfaces of the full-view can be given in
21423 (Process_Full_View): The parent of the full-view does not need to be
21424 a descendant of the parent of the partial view if both parents are
21426 (Analyze_Private_Extension_Declaration): If declaration has an explicit

21441 (Process_Full_View): Improve the check for the "no hidden interface"
21442 rule as defined by AI-396.
21444 2005-12-09 Robert Dewar <dewar@adacore.com>

21500 * sem_cat.adb (Validate_RCI_Subprogram_Declaration): Revise test for
21501 available user-specified stream attributes on limited parameters to
21502 also test the type directly rather than only its underlying type (for
21503 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21504 attributes are visible at the point of the subprogram declaration.
21505 For Ada 2005, the error message is modified to indicate that the
21506 type's stream attributes must be visible (again, only for -gnat05).

21538 types use the corresponding record type. This was not needed before
21539 the implementation of Ada 2005 synchronized types because
21540 concurrent types were never tagged types in Ada 95.

21962 that we are not defining.
21963 (elaborate_expression_1): Do not create constants when creating
21964 variables needed by the debug info: the dwarf2 writer considers that

21983 is provided by the front-end, use that subtype to compute the size of
21984 the deallocated object.

21992 without need to check for the success indication.

21994 pass false instead of 0 as the FORCE argument which is a bool.
21995 (Identifier_to_gnu): Remove checks ensuring that an renamed object
21996 attached to a renaming pointer has been properly stabilized, as no such
21997 object is attached otherwise.

21999 function uses the "target pointer" return mechanism.
22000 Reinstate conversion of the actual to the type of the formal
22001 parameter before any other specific treatment based on the passing

22012 static output of record constructor if all the components are constant.
22013 (gnat_build_constructor): For a record type, sort the list of field
22014 initializers in increasing bit position order.

22017 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22018 types variants, and process special cases of VIEW_CONVERT expressions

22031 generation and we are at the top level, check for a potential violation
22032 of a No_Elaboration_Code restriction.

22176 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22177 for task component, in the case of a limited aggregate. The enclosed
22178 object declaration will create it earlier. Otherwise, in the case of a
22179 nested aggregate, the object may appear in the wrong scope.
22180 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
22181 (Gen_Assign): If the component being assigned is an array type and the
22182 expression is itself an aggregate, wrap the assignment in a block to
22183 force finalization actions on the temporary created for each row of the
22185 (Build_Record_Aggr_Code): Significant rewrite insuring that ctrl
22186 structures are initialized after all discriminants are set so that
22187 they can be accessed even when their offset is dynamic.

22215 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
22216 and related): For a prefix that is an explicit dereference of an
22217 access to unconstrained packed array type, annotate the dereference
22218 with an actual subtype so GIGI can make a correct size computation.
22219 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22220 'Unrestricted_Access, if the designated type is an interface we
22221 add a type conversion to force the displacement of the pointer
22222 to the secondary dispatch table.
22223 Use Universal_Real instead of Long_Long_Float when we need a high
22224 precision float type for the generated code (prevents gratuitous
22225 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22226 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22227 'Terminated for task interface class-wide objects. Generate a call to
22228 the predefined dispatching routine used to retrieve the _task_id from
22229 a task corresponding record.

22253 (Expand_N_If_Statement): When killing a dead then-branch in an
22254 if-statement that has elsif_parts, recompute the Current_Value node
22255 for any entity whose value is known from the condition of the first
22257 (Expand_N_Return_Statement): When returning a mutable record, convert
22258 the return value into its actual subtype in order to help the backend
22259 to return the actual size instead of the maximum. This is another
22260 aftermath of not returning mutable records on the sec-stack anymore.
22262 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
22263 handling of error msg for suspicious reverse range iteration.
22264 (Check_Possible_Current_Value_Condition): Move declaration from body to

22285 (Send_Signal): Release the process handle.
22287 2005-11-14 Robert Dewar <dewar@adacore.com>
22289 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we
22290 need a high precision float type for the generated code (prevents
22291 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
22294 * exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we

22309 attribute of the N_Free_Statement.
22310 Generate itype for classwide designated object in both cases of
22311 user-specified storage pool: specific and class-wide, not only in the
22313 Raise CE when trying to set a not null access type object to null.
22314 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
22315 an explicit loop, because freeze nodes make its position variable.

22538 unit, to prevent scope stack errors.
22539 (Save_References): If the node is an aggregate that is an actual in a
22540 call, rewrite as a qualified expression to preserve some type
22541 information, to resolve possible ambiguities in the instance.
22542 (Instance_Parent_Unit): New global variable to record the ultimate
22543 parent unit associated with a generic child unit instance (associated

22552 scope against package Standard. Add comments and a ??? comment.
22553 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
22554 on a child instance parent to test that the parent equals

22574 full view to construct the full declaration of the derived type.
22575 (Build_Derived_Record_Type): Relax the condition that controls the
22576 execution of the check that verifies that the partial view and

22585 view is a transitive derivation of the ancestor of the partial view.
22586 (Process_Full_View): Rename local subprogram Find_Interface_In_
22587 Descendant to Find_Ancestor_Interface to leave the code more clear.
22588 Remove wrong code that avoids the generation of an error message
22589 when the immediate ancestor of the partial view is an interface.
22590 In addition some minor reorganization of the code has been done to
22591 leave it more clear.
22592 (Analyze_Type_Declaration): If type has previous incomplete tagged
22593 partial view, inherit properly its primitive operations.
22594 (Collect_Interfaces): Make public, for analysis of formal

22607 be included in the interface list.
22608 (Access_Definition): If the designated type is an interface that may
22609 contain tasks, create Master_Id for it before analyzing the expression
22610 of the declaration, which may be an allocator.

22617 * sem_ch6.adb (Check_Conformance): The null-exclusion feature can be
22618 omitted in case of stream attribute subprograms.
22619 (Check_Inline_Pragma): Handle Inline and Inline_Always pragmas that
22620 appear immediately after a subprogram body, when there is no previous
22621 subprogram declaration.
22622 Change name Is_Package to Is_Package_Or_Generic_Package
22623 (Process_Formals): A non null qualifier on a non null named access
22624 type is not an error, and is a warning only if Redundant_Constructs
22627 2005-11-14 Gary Dismukes <dismukes@adacore.com>
22628 Ed Schonberg <schonberg@adacore.com>
22630 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
22631 nested within Analyze_Package_Specification to install the private
22632 declarations and use clauses within each of the parent units of a
22633 package instance of a generic child package.
22634 (Analyze_Package_Specification): When entering a private part of a
22635 package associated with a generic instance or formal package, the
22636 private declarations of the parent must be installed (by calling new
22637 procedure Install_Parent_Private_Declarations).
22638 Change name Is_Package to Is_Package_Or_Generic_Package
22639 (Preserve_Full_Attributes): For a synchronized type, the corresponding
22640 record is absent in a generic context, which does not indicate a
22643 2005-11-14 Ed Schonberg <schonberg@adacore.com>
22645 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22646 not try to rewrite a renamed stream attribute, because the operations
22647 on the type may not have been generated.
22648 Handle properly a renaming_as_body generated for a stream operation
22649 whose default is abstract because the object type itself is abstract.
22650 (Find_Type): If the type is incomplete and appears as the prefix of a
22651 'Class reference, it is tagged, and its list of primitive operations
22652 must be initialized properly.
22653 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22654 private declaration of a parent unit, prior to compiling the private
22655 part of a child unit, find on the scope stack the proper parent entity
22656 on which to link the use clause.
22657 (Note_Redundant_Use): Emit a warning when a redundant use clause is
22659 (Analyze_Object_Renaming): An attribute reference is not a legal object
22660 if it is not a function call.

22663 Ed Schonberg <schonberg@adacore.com>
22665 * sem_eval.adb: Implement d.f flag
22666 (Subtype_Statically_Match): A generic actual type has unknown
22667 discriminants when the corresponding actual has a similar partial view.

22673 Robert Dewar <dewar@adacore.com>
22674 Thomas Quinot <quinot@adacore.com>
22676 * sem_res.adb (Resolve_Call): Provide a better error message whenever
22677 a procedure call is used as a select statement trigger and is not an
22678 entry renaming or a primitive of a limited interface.
22679 (Valid_Conversion): If the operand has a single interpretation do not
22680 remove address operations.
22681 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22682 statement to inhibit warning.
22683 (Resolve_Unary_Op): Do not produce a warning when
22684 processing an expression of the form -(A mod B)
22685 Use Universal_Real instead of Long_Long_Float when we need a high
22686 precision float type for the generated code (prevents gratuitous
22687 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22688 (Resolve_Concatenation_Arg): Improve error message when argument is an
22689 ambiguous call to a function that returns an array.
22690 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
22691 there is an implicit operator in the given scope if we are within an
22692 instance: legality check has been performed on the generic.
22693 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
22694 after resolving operand, to avoid false warnings on overloaded calls.
22696 2005-11-14 Ed Schonberg <schonberg@adacore.com>
22697 Javier Miranda <miranda@adacore.com>
22700 * sem_type.adb (Covers): In an inlined body, a composite type matches
22701 a private type whose full view is a composite type.
22702 (Interface_Present_In_Ancestor): Protect the frontend against
22703 previously detected errors to ensure that its compilation
22704 with assertions enabled gives the same output that its
22705 compilation without assertions.
22706 (Interface_Present_In_Ancestor): Add support for private types.
22707 Change name In_Actual to In_Generic_Actual (clean up)
22708 (Disambiguate): New predicate In_Actual, to recognize expressions that
22709 appear in the renaming declaration generated for generic actuals, and
22710 which must be resolved in the outer context.

22724 for a parameterless procedure.
22725 (Enter_Name): Recognize renaming declarations created for private
22726 component of a protected type within protected operations, so that
22727 the source name of the component can be used in the debugger.

23415 to build an anonymous access type. This allows further cleanup in the
23416 code generated by the expander.
23417 (Expand_Interface_Conversion): If the actual is an access type then
23418 build an internal function to handle the displacement. If the actual
23419 is null this function returns null because no displacement is
23420 required; otherwise performs a type conversion that will be
23421 expanded in the code that returns the value of the displaced actual.
23422 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
23423 conversions that have no effect in the generated code because no
23424 displacement is required. Code cleanup; use local variables to

23434 (Expand_Subtype_From_Expr): Do not build actual subtype if the
23435 expression is limited.
23436 (Find_Interface_Tag): Add code to handle class-wide types and
23437 entities from the limited-view.
23439 * rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
23440 Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,

23470 package can be used for VxWorks 5.x and 6.x
23471 (ATCB_Key, ATCB_Key_Address): Moved to Specific package body to hide
23472 differences between VxWorks 5.x and 6.x

23529 This change also makes gen-soccon self-contained (removing dependencies
23530 upon GCC internal headers).
23532 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
23534 (To_Inet_Addr): Now a procedure instead of a function, more efficient.

23668 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23669 from object notation, the original node is unanalyzed and carries no
23670 semantic information, so that accessiblity checks must be performed on

23684 load comes from a Limited_With_Clause.
23686 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23687 whether a potential circularity is harmless, because it includes units
23688 loaded through a limited_with clause. Extends previous treatment which
23689 did not handle properly arbitrary combinations of limited and
23690 non-limited clauses.

23726 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
23727 position set is provided, we compute one in order to reduce the maximum
23728 length of the keys. This computation first selects a character
23729 position between 1 and the minimum length of the keys in order to
23730 avoid reducing one of the keys to an empty string.
23731 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23732 does not converge. The initialization procedure now comes with a
23733 maximum number of iterations such that when exceeded, an exception is
23734 raised in Compute. The user can initialize this ratio to another value
23736 Reformating and updated headers.
23738 2005-09-01 Javier Miranda <miranda@adacore.com>
23740 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
23741 that given an entity T creates and returns an Itype that duplicates the
23742 contents of T. The returned Itype has the null-exclusion
23743 attribute set to True, and its Etype attribute references T
23744 to keep the association between the two entities.
23745 Update copyright notice
23747 * sem_aggr.adb (Check_Can_Never_Be_Null,
23748 Aggregate_Constraint_Checks, Resolve_Aggregate,
23749 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
23751 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

23757 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
23760 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
23762 Call Set_Result_Definition instead of Set_Subtype_Mark.
23763 (P_Subprogram_Specification): Add parsing of anonymous access result
23764 plus null exclusions. Call Set_Result_Definition instead of
23767 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23768 (P_Access_Type_Definition): Add parsing for an anonymous access result
23769 subtype, plus parsing for null exclusions. Call Set_Result_Definition
23770 instead of Set_Subtype_Mark.
23772 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23773 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
23774 (Result_Definition): New function for N_Function_Specifications.
23775 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
23776 N_Function_Specification.
23777 (Set_Null_Exclusion_Present): Allow this flag for
23778 N_Function_Specification.
23779 (Set_Result_Definition): New procedure for N_Function_Specifications.
23780 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
23781 and N_Function_Specification.
23783 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
23784 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
23785 Add support for LIMITED NEW for Ada 2005 AI-419
23786 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
23787 syntax for anonymous access results.
23788 Replace Subtype_Mark field by Result_Definition in
23789 N_Function_Specification and N_Access_Definition specs.
23790 Add Null_Exclusion_Present to spec of N_Function_Specification.
23791 (Result_Definition): New function for N_Function_Specification and
23792 N_Access_Function_Definition.
23793 (Set_Result_Definition): New procedure for N_Function_Specification and
23794 N_Access_Function_Definition.
23796 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
23797 Result_Definition for cases of N_Access_Function_Definition and
23798 N_Function_Specification.
23799 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
23801 2005-09-01 Vincent Celier <celier@adacore.com>
23803 * lib-writ.adb: Update Copyright notice
23804 (Write_With_Lines): On platforms where file names are case-insensitive,
23805 record the file names in lower case.
23806 (Write_ALI): For D lines, on platforms where file names are
23807 case-insensitive, record the file names in lower case.
23809 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23810 Emmanuel Briot <briot@adacore.com>
23812 * lib-xref.adb (Output_Overridden_Op): Display information on
23813 overridden operation.

23817 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
23820 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
23821 overriding entity information.
23823 2005-09-01 Vincent Celier <celier@adacore.com>
23825 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
23826 including those that are inherited.
23828 2005-09-01 Robert Dewar <dewar@adacore.com>
23830 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
23832 * par-prag.adb: Implement new pragma Debug_Policy
23834 * sem_prag.adb Implement new pragma Debug_Policy
23835 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23836 Component_Size attribute specification. Give warning for ignored pragma
23839 * snames.h, snames.ads, snames.adb: Introduce entries in
23840 Preset_Names for Name_Disp_Asynchronous_Select,
23841 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23842 Name_Disp_Timed_Select.
23843 New pragma Debug_Policy
23845 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23847 Switch -gnata also sets Debug_Pragmas_Enabled
23849 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23850 handle an explicit -gnata when compiling predefined files.
23852 2005-09-01 Vincent Celier <celier@adacore.com>
23854 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23855 directories of projects that have no Ada sources.
23857 2005-09-01 Robert Dewar <dewar@adacore.com>
23859 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23860 (makes a difference for wide characters)
23862 * widechar.adb, widechar.ads:
23863 Add Wide_Char_Byte_Count feature to count chars vs bytes
23865 2005-09-01 Thomas Quinot <quinot@adacore.com>
23866 Ed Schonberg <schonberg@adacore.com>
23867 Robert Dewar <dewar@adacore.com>
23869 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23870 'Address attribute reference with an overloaded prefix, use the
23871 location of the prefix (not the location of the attribute reference) as
23872 the error location.
23873 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23874 a function renaming thereof, is a valid prefix for 'Size (where it is
23875 intepreted as a function call).
23876 (Statically_Denotes_Entity): New predicate to determine whether the
23877 prefix of an array attribute can be considered static.
23880 (Eval_Attr): Fix failure to evaluate Component_Size for
23881 unconstrained arrays (resulted in wrong value in packed case, since
23882 back end cannot handle this case)
23884 2005-09-01 Robert Dewar <dewar@adacore.com>
23886 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23887 error msgs for most common cases.
23888 Use new errout insertion char < (conditional warning)
23890 2005-09-01 Javier Miranda <miranda@adacore.com>
23891 Ed Schonberg <schonberg@adacore.com>
23893 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23894 become local to the whole package.
23895 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23896 the package was already analyzed the new algorithm "replaces" the
23897 real entities by the shadow ones. This is required to ensure that
23898 the order of these entities in the homonym chains does not change;
23899 otherwise we can have undefined references at linking time because
23900 in case of conflicts the external name of the entities will have
23901 a suffix that depends on the order of the entities in the chain.
23902 (Remove_Limited_With_Clause): Complementary code that completes the
23903 new algorithm and replaces the shadow entities by the real ones.
23904 (Install_Limited_Withed_Unit): When unchaining entities before the
23905 installation of the shadow entities, only regular entities of the
23906 public part must be taken into account. This is required to
23907 keep this routine in synch with the work done by Remove_Limited_
23909 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
23910 even if unit is analyzed, because the analysis of the unit is
23911 idempotent in any case, and the limited view of the unit may have to
23912 be installed for proper visibility.
23913 (Expand_Limited_With_Clause): Even if the unit in the implicit
23914 with_clause has been analyzed already, a limited view of the package
23915 must be built for the current context, if it does not exist yet.
23917 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23918 Javier Miranda <miranda@adacore.com>
23919 Gary Dismukes <dismukes@adacore.com>
23921 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
23922 defining entity for the instance body, make a new defining identifier
23923 rather than copying the entity of the spec, to prevent accidental
23924 sharing of the entity list.
23925 (Check_Private_View): When exchanging views of private types, build the
23926 list of exchanged views as a stack, to ensure that on exit the exchanges
23927 are undone in the proper order.
23928 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
23929 Restore the compilation environment in case of instantiation_error.
23930 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
23931 for an anonymous access result.
23932 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
23933 (Formal_Entity): Handle properly the case of a formal package that
23934 denotes a generic package renaming.
23936 2005-09-01 Thomas Quinot <quinot@adacore.com>
23938 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
23939 clause if the array aggregate is surrounded by parentheses.
23941 2005-09-01 Cyrille Comar <comar@adacore.com>
23942 Gary Dismukes <dismukes@adacore.com>
23943 Ed Schonberg <schonberg@adacore.com>
23944 Javier Miranda <miranda@adacore.com>
23946 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
23948 to check if a type is Constrained in cases related to code generation
23949 (rather than semantic checking) since otherwise we do not generate
23950 similar code for mutable private types depending if their
23951 discriminants are visible or not.
23952 (Check_Abstract_Overriding): Do not complain about failure to override
23953 the primitive operations used in dispatching selects since they will
23954 always be overriden at the freeze point of the type.
23955 (Access_Definition): Separate out handling for resetting the scope
23956 of an anonymous access function result type. Retrieve the scope
23957 of the associated function rather than using Current_Scope, which
23958 does not have a consistent value (depends on whether we're in the
23959 middle of analyzing formal parameters). Add ??? comment about
23960 finding a cleaner way to handle the special cases of scope setting.
23961 (Process_Incomplete_Dependents): A protected operation is never a
23962 dispatching operation (only its wrapper may be).
23963 (Build_Derived_Record_Type): In case of tagged private types that
23964 implement interfaces add derivation of predefined primitive
23966 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
23967 by two parameters that are used in case of derivation from abstract
23968 interface types: No_Predefined_Prims is used to avoid the derivation
23969 of predefined primitives from the interface, and Predefined
23970 Prims_Only is used to complete the derivation predefined primitives
23971 in case of private tagged types implementing interfaces.
23972 Fix typo in comments
23973 (Find_Interface_In_Descendant): Protect the frontend against
23974 wrong code with large circularity chains.
23975 (Is_Private_Overriding): Add support for entities overriding interface
23976 subprograms. The test failed because Entities associated with overriden
23977 interface subprograms are always marked as hidden (and used to build
23978 the secondary dispatch table); in this case the overriden entity is
23979 available through the field abstract_interface_alias (cf. override_
23980 dispatching_operation)
23981 (Access_Definition): Set the scope of the type to Current_Scope for the
23982 case of a function with an anonymous access result type.
23983 (Access_Subprogram_Declaration): Handle creation of the type entity for
23984 an access-to-function type with an anonymous access result.
23985 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
23986 in handling for N_Access_Function_Definition.
23987 (Analyze_Subtype_Declaration): Modify the text of error message.
23988 (Derived_Type_Declaration): Modify the text of error message.
23989 (Process_Subtype): Modify the text of error message plus cleanup
23990 of one redundant error message.
23991 (Analyze_Component_Declaration): Code cleanup.
23992 (Analyze_Object_Declaration): Code cleanup.
23993 (Analyze_Subtype_Declaration): Propagate the null-exclusion
23994 attribute in case of access types. Code cleanup.
23995 (Array_Type_Declaration): Code cleanup.
23996 (Process_Discriminants): Create the new null-excluding itype
23997 if required. Code cleanup.
23998 (Process_Subtype): Create the new null-excluding itype if
23999 required. Code cleanup.
24000 (Build_Derived_Record_Type): Code cleanup to avoid calling
24001 twice the subprogram derive_subprograms in case of private
24002 types that implement interfaces. In this particular case the
24003 subprogram Complete_Subprograms_Derivation already does the
24004 job associated with the second call.
24006 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24007 conversion to the full view when generating an operation for a
24008 discriminant whose type may currently be private.
24010 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24011 Javier Miranda <miranda@adacore.com>
24013 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24014 V (Obj.F), the rewriting does not involve the indexed component, but
24015 only the selected component itself.
24016 Do not apply the transformation if the analyzed node is an actual of a
24017 call to another subprogram.
24018 (Complete_Object_Operation): Retain the entity of the
24019 dispatching operation in the selector of the rewritten node. The
24020 entity will be used in the expansion of dispatching selects.
24021 (Analyze_One_Call): Improve location of the error message associated
24023 (Analyze_Selected_Component): No need to resolve prefix when it is a
24024 function call, resolution is done when parent node is resolved, as
24026 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24027 when attempting to resolve a call transformed from its object notation.
24028 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24029 of the argument list for each interpretation of the operation.
24030 (Try_Object_Operation): The designated type of an access parameter may
24031 be an incomplete type obtained through a limited_with clause, in which
24032 case the primitive operations of the type are retrieved from its full
24034 (Analyze_Call): If this is an indirect call, and the return type of the
24035 access_to_subprogram is incomplete, use its full view if available.
24037 2005-09-01 Javier Miranda <miranda@adacore.com>
24038 Gary Dismukes <dismukes@adacore.com>
24040 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24041 access types the null-exclusion and access-to-constant attributes must
24043 (Analyze_Return_Statement): When the result type is an anonymous access
24044 type, apply a conversion of the return expression to the access type
24045 to ensure that appropriate accessibility checks are performed.
24046 (Analyze_Return_Type): For the case of an anonymous access result type,
24047 generate the Itype and set Is_Local_Anonymous_Access on the type.
24048 Add ??? placeholder for check to disallow returning a limited object
24049 in Ada 2005 unless it's an aggregate or a result of a function call.
24050 Change calls from Subtype_Mark to Result_Definition.
24051 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24052 Result_Definition in call to Make_Function_Specification.
24053 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24054 Set_Result_Definition.
24055 (Make_Inequality_Operator): Change formal Subtype_Mark to
24056 Result_Definition in call to Make_Function_Specification.
24057 (Process_Formals): Create the new null-excluding itype if required.
24058 (New_Overloaded_Entity): For an entity overriding an interface primitive
24059 check if the entity also covers other abstract subprograms in the same
24060 scope. This is required to handle the general case, that is, overriding
24061 other interface primitives and overriding abstract subprograms inherited
24062 from some abstract ancestor type.
24063 (New_Overloaded_Entity): For an overriding entity that comes from
24064 source, note the operation that it overrides.
24065 (Check_Conformance, Type_Conformant): Addition of one new formal
24066 to skip controlling formals in the analysis. This is used to
24067 handle overloading of abstract interfaces.
24068 (Base_Types_Match): Add missing case for types imported from
24069 limited-with clauses
24070 (New_Overloaded_Entity): Add barrier to protect the use of
24071 the "alias" attribute.
24073 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24075 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24076 verify that the procedure and the entry are mode conformant.
24077 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24078 as a different operator, which is often a cut-and-paste error.
24080 2005-09-01 Javier Miranda <miranda@adacore.com>
24081 Ed Schonberg <schonberg@adacore.com>
24083 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24084 used in controlling parameters exclude null because it is necessary to
24085 read the tag to dispatch, and null has no tag.
24086 (Override_Dispatching_Operation): If the previous operation is inherited
24087 from an interface, it becomes hidden and does not participate in later
24090 2005-09-01 Javier Miranda <miranda@adacore.com>
24091 Ed Schonberg <schonberg@adacore.com>
24092 Gary Dismukes <dismukes@adacore.com>
24094 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24095 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24096 the expander will generate the corresponding run-time check to evaluate
24098 (Resolve_Call): Check for legal type of procedure name or prefix that
24099 appears as a trigger in a triggering alternative.
24100 (Valid_Conversion): If expression is ambiguous and the context involves
24101 an extension of System, remove System.Address interpretations.
24102 (Resolve_Qualified_Expression): Reject the case of a specific-type
24103 qualification applied to a class-wide argument. Enhance comment
24104 to explain checking of Original_Node.
24105 (Resolve_Type_Conversion): The location of the error message was not
24106 general enough to handle the general case and hence it has been removed.
24107 In addition, this patch improves the text of the message.
24108 (Resolve_Type_Conversion): Add missing support for access to interface
24110 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24111 do not expand if the expression is the actual in a call, because proper
24112 expansion will take place when the call itself is expanded.
24113 (Resolve_Allocator): If the context is an unchecked conversion, the
24114 allocator inherits its storage pool, if any, from the target type of
24117 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24118 Javier Miranda <miranda@adacore.com>
24120 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24121 inherited interface operation that has an implementation, use the
24122 implementation to avoid spurious ambiguities.
24123 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24124 use the Corresponding_Record_Typ attribute to look for the interface
24125 because it is set by the expander (and hence it is not always
24126 available). For this reason we traverse the list of interfaces
24127 (available in the parent of the concurrent type).
24128 (Interface_Present_In_Ancestor): Handle entities from the limited view
24130 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24132 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24133 from the list of required components.
24134 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24135 primitive procedure of a limited interface with a controlling first
24137 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24139 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24140 capture if it is generated in the second operand of a short-circuit
24142 Do not capture values for variables with address clauses.
24143 (Is_Object_Reference): Treat a function call as an object reference only
24144 if its type is not Standard_Void_Type.
24146 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24148 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24149 to a variable that is statically known to be constant.

24161 Document that bounds of result of Base_Name match the input index
24163 Add documentation on environment variable syntax for Expand_Path
24165 * gnat_ugn.texi: Update documentation to include mention of -m switches
24166 Document new treatment of wide characters in max line length
24168 Remove -gnatL/-gnatZ switches, no longer used.
24169 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24172 * gnat_rm.texi: Add doc for two argument form of pragma
24173 Float_Representation.
24174 Add documentation for pragma No_Strict_Aliasing
24175 Add note that explicit component clause overrides pragma Pack.
24176 Add documentation of pragma Debug_Policy

24932 longer protected objects. They have been replaced by lower-level
24933 suspension objects made up by a mutex and a condition variable (or
24934 their equivalent given a particular OS) plus some internal data to
24935 reflect the state of the suspension object.
24936 (Initialize, Finalize): Add this initialization procedure for
24937 Suspension_Object, which is a controlled type.
24938 (Finalize): Add the finalization procedure for Suspension_Object,
24939 which is a controlled type.

25400 are to be inlined by the front-end. When the body comes from an
25401 instantiation, a reference to Unchecked_Conversion will be an
25402 Expanded_Name, even though the body has not been analyzed yet.

25423 object or component (that is, when Is_Local_Anonymous_Access is true).
25424 Prevent the special checks for conversions of access discriminants in
25425 the case where the discriminant belongs to a nonlimited type, since

25427 way as a normal component of an anonymous access type.
25428 (Resolve_Allocator): When an allocator's designated type is a class-wide
25429 type, check that the accessibility level of type given in the
25430 allocator's expression or subtype indication is not statically deeper

25442 (Resolve_Actuals): Enable full error reporting on view conversions
25443 between unrelated by_reference array types.
25444 The rule for view conversions of arrays with aliased components is
25445 weakened in Ada 2005.
25446 Call to obsolescent subprogram is now considered to be a violation of
25447 pragma Restrictions (No_Obsolescent_Features).
25448 (Check_Direct_Boolean_Operator): If the boolean operation has been
25449 constant-folded, there is nothing to check.
25450 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25451 check on possible violation of restriction No_Direct_Boolean_Operators
25452 until after expansion of operands, to prevent spurious errors when

25487 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
25488 both bound checks, rather than a conjunction.
25489 (Insert_Valid_Check): If the expression is an actual that is an indexed
25490 component of a bit-packed array, force expansion of the packed element
25491 reference, because it is specifically inhibited elsewhere.

25504 may be deallocated by Normalize_Arguments.
25505 (Collect_Arguments): Eliminate empty arguments
25507 * gnatcmd.adb (All_Projects): New Boolean flag, initialized to False,
25508 and set to True when -U is used for GNAT PRETTY or GNAT METRIC.

26457 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26458 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26459 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26460 analyzed if expansion is disabled (which could otherwise cause spurious
26461 error messages if expansion has been disabled due to previous
26462 (unrelated) errors).
26464 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26465 is disabled, the entity denoted by the argument is the access type
26466 itself, not an underlying record type, so there is no need to go back
26467 to the Corresponding_Remote_Type.
26469 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26470 Robert Dewar <dewar@adacore.com>
26472 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
26473 expand a call to an instance of
26474 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the

26476 check is also generated, to ensure that the tag passed to the instance
26477 denotes a type in the class.
26478 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26479 of Name_Generic_Dispatching_Constructor.
26481 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

26497 generic formal subprogram association for an abstract formal subprogram.
26498 Check that the attribute is a primitive stream attribute (and not
26499 a class-wide stream attribute) and then rewrite the attribute name
26500 as the name of the appropriate compiler-generated stream primitive.

26512 itype whose parent is controlled and not yet frozen, do not create a
26513 freeze node for the itype if expansion is disabled.
26515 2005-03-29 Vincent Celier <celier@adacore.com>
26517 * make.adb (Gnatmake): Don't fail if the main project file is declared
26518 as having no Ada sources. Do not display message "no sources to
26519 compile" in quiet output.

26539 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26540 rather than proceed ahead using a junk attribute name.
26542 2005-03-29 Vincent Celier <celier@adacore.com>
26544 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26546 * prj-part.adb (Parse_Single_Project): Set the location of a project
26547 on its defining identifier, rather than on the reserved word "project".
26549 * prj-proc.adb (Expression): Adapt to the fact that default of external
26550 references may be string expressions, not always literal strings.
26551 (Recursive_Process): Set Display_Name equal to Name
26552 when Location is No_Location, that is when there is no actual file.
26553 Get the Display_Name of the project from the source, when it is not a
26555 (Process): Use the Display_Name in error messages
26557 * prj-strt.adb (External_Reference): Allow default to be string
26558 expressions, not only literal strings.
26560 2005-03-29 Vincent Celier <celier@adacore.com>

26568 forbid conversion of a local access-to-subprogram type to a remote one.
26570 * sem_util.adb (Wrong_Type): For a record type that is the expanded
26571 equivalent type for a remote access-to-subprogram type, go back to the
26572 original RAS entity when displaying an error message, so the casing is
26573 the original source casing.

26577 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
26580 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26582 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26583 subtype if code is being pre-analyzed, to prevent un-expanded
26584 references to protected formals, among others.
26585 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26586 interpretation that can be a call, include the result of the call as a
26587 possible interpretation of the dereference.
26589 * sem_ch5.adb (Process_Bounds): Determine type of range by
26590 pre-analyzing a copy of the original range, and then analyze the range
26591 with the expected type.
26593 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26594 with an overloaded prefix where not all interpretations yield an
26595 access to subprogram, do not rewrite node as a call.
26596 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26597 the node as a call once the context identifies the interpretation of
26598 the prefix whose call yields the context type.
26599 (Valid_Conversion): For the case of a conversion between
26600 local access-to-subprogram types, check subtype conformance using
26601 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26602 detailed error message.

26606 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26607 indicator, indicate that the formal can never be null.
26608 (Process_Formals): If a formal has a non_null indicator, insert the
26609 resulting subtype immediately before the enclosing subprogram decl,
26610 and not at the beginning of the corresponding declarative part, to
26611 prevent access before elaboration (Ada2005).

26720 to install the visible declarations of the enclosing scope of a
26721 record_type_with_private to establish the proper visibility before
26722 freezing the entity and related subprograms.

26734 explanatory error message (including the name of the missing attribute).
26735 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
26736 subprogram determines whether a default implementation exists for a
26737 given stream attribute.
26738 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
26739 Determine whether to generate a default implementation for each stream
26740 attribute separately, as this depends on the specific attribute.
26742 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
26743 limited extension where a stream attribute is missing for a limited
26744 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

27310 (P_Protected): Modified to handle the list of interfaces in a
27311 protected type declaration.
27313 2005-03-15 Doug Rupp <rupp@adacore.com>
27314 Vincent Celier <celier@adacore.com>
27316 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27317 (Gen_Output_File_C): Likewise.
27318 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
27320 2005-03-15 Thomas Quinot <quinot@adacore.com>
27322 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27323 is an N_Raise_Constraint_Error node, create a new copy of it without
27324 going through a call to Duplicate_Subexpr.
27326 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
27327 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27328 Nicolas Setton <setton@adacore.com>
27329 Ed Schonberg <schonberg@adacore.com>
27335 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27336 representation clause that prescribes a size not equal to the rounded
27337 size of their types.
27338 (gnat_to_gnu_entity, case E_Component): Always look at
27339 Original_Record_Component if Present and not the entity.
27340 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27341 of tagged extension types by not making field for components that are
27343 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27344 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27345 expression to the type of the object when the object is constant.
27346 Reverse defer_debug_incomplete_list before traversing it, so that trees
27347 are processed in the order at which they were added to the list. This
27348 order is important when using the stabs debug format.
27349 If we are deferring the output of debug information, also defer this
27350 output for a function return type.
27351 When adding fields to a record, prevent emitting debug information
27352 for incomplete records, emit the information only when the record is
27354 (components_to_record): New parameter defer_debug.
27355 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27356 (gnat_to_gnu_field_decl): New function.
27357 (substitution_list, annotate_rep): Call it.
27358 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27359 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27360 No longer update discriminants to not be a COMPONENT_REF.
27361 (copy_alias_set): Strip padding from input type; also handle
27362 unconstrained arrays properly.
27364 * gigi.h (write_record_type_debug_info): New function.
27365 Convert to use ANSI-style prototypes. Remove unused
27366 declarations for emit_stack_check, elab_all_gnat and
27367 set_second_error_entity.
27368 (gnat_to_gnu_field_decl): New decl.
27370 * utils.c (write_record_type_debug_info): New function.

27373 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27374 (update_pointer_to): Fix pasto.
27375 (convert) <UNION_TYPE>: Accept slight type variations when
27376 converting to an unchecked union type.
27378 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27379 replace the N_Freeze_Entity with a null statement.
27381 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27382 within a constrained subcomponent of an enclosing record, place the
27383 freeze nodes in the scope stack entry for the enclosing record.
27384 (Undelay_Type): New Subprogram.
27385 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27386 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27387 within records; allow them to have freeze nodes if their base types
27390 * exp_util.adb (Remove_Side_Effects): Properly test for
27391 Expansion_Delayed and handle case when it's inside an
27392 N_Qualified_Expression.
27394 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27395 Comes_From_Generic, to recognize accurately that the parent type in a
27396 derived type declaration can be traced back to a formal type, because
27397 it is one or is derived from one, or because its completion is derived
27399 (Constrain_Component_Type): If component comes from source and has no
27400 explicit constraint, no need to constrain in in a subtype of the
27402 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27403 Minor change to propagate Is_Ada_2005 flag
27405 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27406 Expansion_Delayed is False.
27407 (assoc_to_constructor): Ignore fields that have a
27408 Corresponding_Discriminant.
27409 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27410 function returns "by target", dereference the target pointer using the
27411 type of the actual return value.
27412 <all>: Be prepared for a null gnu_result.
27413 (processed_inline_subprograms): Check flag_really_no_inline
27414 instead of flag_no_inline.
27415 (set_second_error_entity): Remove unused function.

27420 2005-03-15 Robert Dewar <dewar@adacore.com>
27421 Ed Schonberg <schonberg@adacore.com>
27422 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27424 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27425 Must_Be_Byte_Aligned for cases where we do not need to use a
27426 System.Pack_nn unit.
27428 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27430 Needed now that we do some processing for IN parameters as well. This
27431 may well fix some unrelated errors.
27432 (Expand_Call): Handle case of unaligned objects (in particular those
27433 that come from packed arrays).
27434 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27435 renamed entity is an inherited operation, re-expand the call using the
27436 original operation, which is the one to call.
27437 Detect attempt to inline parameterless recursive subprogram.
27438 (Represented_As_Scalar): Fix to work properly with private types
27439 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27440 accurate estimate. Yields True in far fewer cases than before,
27441 improving the quality of code that depends on this test.
27443 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27444 over both visible and private declarations to remove them from tree,
27445 and mark subprograms declared in package as eliminated, to prevent
27446 spurious use in subsequent compilation of generic units in the context.
27448 * exp_util.ads: Minor cleanup in variable names
27450 * sem_eval.ads, sem_eval.adb: Minor reformatting
27451 (Compile_Time_Known_Bounds): New function
27453 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27455 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27456 determining whether an unchecked conversion is needed for the argument
27457 of an initialization call.
27459 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27461 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27462 that appears in the instantiation rather than the internal subtype
27463 generated in the wrapper package, to avoid anomalies in gigi when the
27464 target is derived from a private type whose full view is an access type.
27466 2005-03-15 Robert Dewar <dewar@adacore.com>
27468 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27470 Add documentation to replace the use of this flag
27471 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27474 2005-03-15 Thomas Quinot <quinot@adacore.com>
27476 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27477 here from exp_attr so it can be shared between exp_attr and exp_dist.
27478 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27479 all TSS names, not a subset thereof, and the previous name introduced
27480 an unnecessarily confusion that a distinction might exist between
27481 "OK" TSS names and some "not OK" TSS names.
27483 2005-03-15 Doug Rupp <rupp@adacore.com>
27485 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27488 2005-03-15 Pascal Obry <obry@adacore.com>
27489 Eric Botcazou <ebotcazou@adacore.com>
27493 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27494 when IN_RTS. This is to work around a bootstrap path problem.
27496 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27497 table and pass it to __gnat_install_SEH_handler().
27498 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27500 * lang.opt: Fix specification of -fRTS=.
27502 2005-03-15 Doug Rupp <rupp@adacore.com>
27503 Bernard Banner <banner@adacore.com>
27504 Vincent Celier <celier@adacore.com>
27505 Arnaud Charlet <charlet@adacore.com>
27508 This change works fine when gnatlib is built from the gcc directory,
27509 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27510 is not passed to ada/Makefile.in, so more work is needed by a
27511 Makefile/configure expert.
27513 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27514 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27515 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27517 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27518 Run ranlib on libgccprefix.a
27519 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27520 (ADA_INCLUDE_SRCS): Split Ada packages.
27522 2005-03-15 Robert Dewar <dewar@adacore.com>
27524 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27526 * impunit.adb: Add GNAT.UTF_32
27528 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27530 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27531 now uses GNAT.UTF_32).
27533 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27534 capabilities for categorizing characters using Unicode categories
27536 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27538 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27539 instantiation that has been rewritten as a package body, retrieve spec
27540 to generate proper name for implicit_with_clause.
27541 (Install_Parents): Recognize a parent that is an instantiation but has
27542 been rewritten as a package declaration during analysis.
27544 2005-03-15 Javier Miranda <miranda@adacore.com>
27545 Ed Schonberg <schonberg@adacore.com>
27547 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27548 parameter reported some error we immediately return. This improves the
27549 behaviour of the frontend in case of errors.
27550 (Install_Parent, Remove_Parent): Introduce new flag
27551 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27552 ancestor of a generic child unit, when the child is being instantiated.
27553 (Inline_Instance_Body): If we are compiling the private
27554 part or the body of a child unit, restore the proper visibility of the
27555 parents after compiling the instance body.
27557 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27558 Javier Miranda <miranda@adacore.com>
27561 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27562 of a private type, in which case it is underlying_type that denotes
27563 the proper task. Also modified to use the new entity attribute
27564 that is directly available in the task type and task subtype entities
27565 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27566 arrays when other dimensions than the first are constrained by
27567 discriminants of an enclosing record.
27568 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27569 a combination of indexed and selected components, find ultimate entity
27570 and generate the appropriate reference for it, to suppress spurious
27572 (Note_Possible_Modification): If an entity name has no entity, return.
27573 (Is_Variable): A function call never denotes a variable.
27574 (Requires_Transient_Scope): For record types, recurse only on
27575 components, not on internal subtypes that may have been generated for
27576 constrained components.
27578 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27580 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27581 Eliminated as candidates for resolution. Both efficient, and avoids
27582 anomalies with operators declared in deleted code.
27583 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27584 expansion is disabled (as when compiling a generic) to prevent spurious
27585 warnings on prefixes of selected components.
27587 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27589 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27590 attached to a list before checking whether it appears in the private
27591 declarations of the current package.
27592 (Make_Inequality_Operator): Insert declaration in proper declarative
27593 list rather than just setting the Parent field, so that
27594 Is_Private_Declaration can handle it properly.
27596 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27598 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27599 a renaming a body, check that the renamed subprogram in not intrinsic.
27600 (Find_Direct_Name): If several use_visible entities hide
27601 each other, and the context is a predefined file compiled through
27602 rtsfind, keep only the entity that comes from a predefined file.
27604 2005-03-15 Geert Bosch <bosch@adacore.com>
27606 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27607 long float padding to also cover AMD64 and IA64.
27609 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27611 * s-imgwch.adb: Add with and use of Interfaces.
27612 (Img_Wide_Character): Change type of Val to Unsigned_16.
27613 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27615 2005-03-15 Matthew Gingell <gingell@adacore.com>
27617 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
27619 2005-03-15 Robert Dewar <dewar@adacore.com>

27623 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
27625 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
27627 2005-03-15 Robert Dewar <dewar@adacore.com>

27651 procedures in the bug boxes for various GNAT builds.
27653 2005-03-15 Vincent Celier <celier@adacore.com>
27655 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

27660 Cyrille Comar <comar@adacore.com>
27661 Sergey Rybin <rybin@adacore.com>
27663 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
27664 too specific and long-winded to be appropriate for the GNAT User's
27666 Warn about use of GCC switches not documented in the GNAT User's Guide,
27667 as these may cause generated code to not conform to Ada semantics.
27668 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
27669 Add documentation for -gnat95 and -gnat05 switches
27670 Remove paragraph documenting obsolete way to refer to third party
27672 Add a few references to Ada_05 that were missing.
27673 Update documentation on -gnatZ/-gnatL.

28089 the formal subprogram.
28090 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28091 which is an unclean use of that field, we set the new field

28110 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28111 mark in function specification, in a context where the formals are
28112 visible and hide outer homographs.
28114 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28115 as the tagged type for the cases of abstract formal subprograms and
28116 renamings of those. Clean up spec comments.
28117 (Check_Dispatching_Context): Add error message to indicate "abstract
28118 procedure", covering the case of a call to a formal abstract procedure
28119 that has statically tagged operands.
28120 (Check_Dispatching_Call): Check for the case of an actual given by
28121 a tag-indeterminate function call whose type is an ancestor of the
28122 containing call's associated tagged type. This situation can occur
28123 for inherited primitives with function defaults. In this case we
28124 use the tagged type's tag directly as the controlling argument for

28229 component of an array of arrays in an assignment context, and the
28230 aggregate has component associations that require sliding on

28268 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
28269 (GNATBIND_OBJS): Idem.
28271 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28272 routine takes a new parameter (a pointer to the exception registration

28276 Update copyright notice.
28278 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28279 record and initialize it by calling __gnat_install_SEH_handler.

28317 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28318 with expansion disabled. The actual subtype is needed among other
28319 places when the selected component appears in the context of a loop
28320 bound, and denotes a packed array.
28321 (Operator_Check): Always use the first subtype in the
28322 error message, to avoid the appearance of internal base types.
28323 (Transform_Object_Operation): Copy each actual in full
28324 to the parameter associations of the constructed call, rather than
28325 using the shallow copy mechanism of New_Copy_List. This ensures that
28326 the chaining of named associations is done properly.
28327 (Complete_Object_Operation): Rewrite node, rather than
28328 replacing it, so that we can trace back to the original selected
28331 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28332 and calls that use object notation, if the called function is not
28333 declared in a withed unit, place the elaboration constraint on the
28334 unit in the context that makes the function accessible.
28335 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28336 imposes an elaboration constraint between two packages.
28338 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28340 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28341 views of a private type after handling its private dependents, to
28342 maintain proper stack discipline between entry and exit from the

28365 * xr_tabls.ads: Add ??? comment for missing overall comment
28367 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28368 we now use by default.
28370 * xsnames.adb: Adjust end of file test to look for five space followed
28371 by '#' instead of six spaces. The format of xsnames.adb was modified
28372 in the last update.

28377 * clean.adb: Minor reformatting.
28379 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28380 gnatname.adb: Minor reformatting

28383 * csets.adb: Eliminate obsolete comment
28385 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28388 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28390 2005-02-09 Sergey Rybin <rybin@adacore.com>
28392 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28393 the difference between compact and incompact layout and add the record
28394 representation clause to the example illustrating different layouts.
28395 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28396 component clauses").
28398 2005-02-09 Florian Villoing <villoing@adacore.com>
28400 * gnat_ugn.texi: Fix typos.
28401 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

28700 2005-01-03 Olivier Hainque <hainque@adacore.com>
28702 * decl.c (compatible_signatures_p): New function. The intended purpose
28703 is to check if two function signatures for a call-site and a callee are
28704 compatible enough for the call to be valid. The underlying purpose is
28705 to check if a call to a mapped builtin is using the right interface.
28706 The current code actually does not check antyhing - this a placeholder

29246 used to record an implicit dereference as a read operation on its
29247 prefix when operating under -gnatc. Necessary to avoid spurious
29248 'variable assigned but never read' warnings in that mode.
29249 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29250 is a non-overloaded implicit dereference, call the above subprogram to
29251 ensure proper recording of references.
29253 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29255 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

29269 2004-12-07 Thomas Quinot <quinot@adacore.com>
29271 * g-socket.ads (Get_Host_By_Address, Get_Host_By_Name): Clarify
29272 documentation of the behaviour of these functions when passed an IP
29273 address that has no record in the system hosts database and no reverse
29276 * cstand.adb, a-tags.ads: Fix typos in comment.
29278 2004-12-07 Robert Dewar <dewar@adacore.com>

29293 2004-12-07 Vincent Celier <celier@adacore.com>
29294 Sergey Rybin <rybin@adacore.com>
29296 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
29297 Files" with the new tool and package names.
29298 Reformatting to suppress most of the warnings for line too long
29299 Document the new section "Project Search Path:" in the output of
29301 Add gnatmetric section
29303 2004-12-07 Vincent Celier <celier@adacore.com>
29305 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29306 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29307 and -eit to -ept. Added qualifier
29308 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29310 2004-11-27 Andreas Schwab <schwab@suse.de>
29312 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29314 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29316 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29317 internal implementation unit GNAT.Sockets.Thin,
29318 as their usage for sockets is non-portable (using the read and write
29319 functions from the system runtime library is fine on UNIX but won't
29320 work under Windows).
29322 * mingw32.h: Update copyright notice.
29324 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29326 * ada-tree.h: Minor reformatting of previous change to avoid lines
29327 longer than 79 characters.
29329 2004-11-25 Olivier Hainque <hainque@adacore.com>
29331 * tb-gcc.c: GCC infrastructure based implementation of

29348 Style_Check_Order_Subprograms.
29350 2004-11-18 Arnaud Charlet <charlet@adacore.com>
29352 * adaint.h, adaint.c
29353 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
29355 Add also a cast to kill another warning.
29356 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
29357 parameter with the priority class of the parent process instead of
29358 always using the NORMAL_PRIORITY_CLASS.
29359 (__gnat_dup): New function.
29360 (__gnat_dup2): New function.
29361 (__gnat_is_symbolic_link): Enable the effective body of this
29362 function when __APPLE__ is defined.
29364 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
29367 2004-11-18 Olivier Hainque <hainque@adacore.com>
29369 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
29370 address of which may be used to represent "others" and "all others"
29371 choices in exception tables, instead of the current harcoded
29372 (void *)0 and (void *)1.
29373 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29375 * gigi.h (others_decl, all_others_decl): New decls representing the
29376 new Others_Value and All_Others_Value objects.
29377 (struct attrib): Rename "arg" component as "args", since GCC expects a
29378 list of arguments in there.
29380 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29381 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29384 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29385 others_decl and all_others_decl instead of hardcoded dummy addresses
29386 to represent "others" and "all others" choices, which is cleaner and
29387 more flexible with respect to the possible eh pointer encoding policies.
29389 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29390 (process_attributes): Account for the naming change of the "args"
29391 attribute list entry component.
29393 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29394 cumulating attributes for different entities into a single list.
29395 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29396 attributes for the current entity and propagate first subtype
29397 attributes to other subtypes.
29398 <E_Procedure>: Attribute arguments are attr->args and not
29399 attr->arg any more.
29400 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29401 argument provided, as this is what GCC expects. Use NULL_TREE instead
29404 2004-11-18 Robert Dewar <dewar@adacore.com>
29406 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
29407 Minor reformatting througout (including new function specs)
29408 Add ??? comments asking for clarification.
29410 2004-11-18 Thomas Quinot <quinot@adacore.com>
29412 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
29413 incomplete duplicate implementation of this subprogram from butil.
29415 2004-11-18 Thomas Quinot <quinot@adacore.com>
29417 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
29418 procedures factors the common processing for building an RPC receiver
29419 for an RCI package or an RACW type.
29420 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
29421 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
29422 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
29424 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
29426 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
29428 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
29429 distribution subprogram identifiers that are either subprogram numbers

29432 string distribution identifiers assigned to a given subprogram.
29433 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29434 (Add_RAS_Dereference_TSS): Add comments.
29435 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29436 is not referenced yet because it will be used by the PolyORB DSA
29438 (Insert_Partition_Check): Remove fossile code.
29439 (First_RCI_Subprogram_Id): Document this constant.
29440 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29442 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29443 replaced with calls to Get_Library_Unit_Name_String. Previously there
29444 were several instances of the same code in different locations in the
29445 compiler; this checkin completes the replacement of all of these
29446 instances with calls to a common subprogram.
29447 Minor reformatting.
29449 * sem_dist.adb: Remove comment noting that RPC receiver generation
29450 should be disabled for RACWs that implement RASs.
29451 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.

29455 qualified name of a library unit into the name buffer.
29456 (Note_Possible_Modification): Generate a reference only
29457 if the context comes from source.
29459 * snames.ads (PCS_Names): New subtype corresponding to names of
29460 supported implementations of the Partition Communication Subsystem
29461 (PCS) (i.e. the runtime library support modules for the distributed

29471 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
29473 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
29475 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29476 (Expand_Pragma_Psect_Object): New procedure
29477 These procedures contain the revised and cleaned up processing for
29478 these two pragmas. This processing was formerly in Sem_Prag, but
29479 is more appropriately moved here. The cleanup involves making sure
29480 that the pragmas are properly attached to the tree, and that no
29481 nodes are improperly shared.
29483 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29484 pragmas to Exp_Prag, which is more appropriate.
29485 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29486 check for duplicates Remove use of Is_Psected flag, no longer needed.
29487 Use new Make_String_Literal function with string.
29489 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29490 that are functions return universal values, that have to be converted
29491 to the context type.
29492 Use new Make_String_Literal function with string.
29493 (Get_Stream_Convert_Pragma): New function, replaces the use of
29494 Get_Rep_Pragma, which had to be kludged to work in this case.
29496 * freeze.adb: Use new Has_Rep_Pragma function
29498 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29499 function with string.
29500 Use new Has_Rep_Pragma function.
29502 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29505 2004-11-18 Robert Dewar <dewar@adacore.com>
29507 * errout.ads, errout.adb: (First_Sloc): New function
29509 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29510 check (-gnatyx) instead of being included as a redundant construct
29513 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29514 Style_Check_Order_Subprograms.
29516 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29517 stylesw.adb: Add Style_Check_Xtra_Parens
29519 * usage.adb: Add line for -gnatyx (check extra parens)
29521 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29523 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29524 Robert Dewar <dewar@adacore.com>
29526 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29527 discriminant of a constrained subtype, analyze the copy of the
29528 corresponding constraint, because in some cases it may be only
29529 partially analyzed.
29530 Removes long-lived ??? comments.
29532 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29533 handled controlled or secondary-stack expressions within the
29534 iteration_scheme of a loop.
29536 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29537 bounds that may contain functions calls, to prevent memory leaks when
29538 the bound contains a call to a function that uses the secondary stack.
29539 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29540 generate temporaries for loop bounds that might contain function calls
29541 that require secondary stack and/or finalization actions.
29543 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29544 selected component and the selector is overloadable (not just a
29545 function) treat as function call, Analyze_Call will disambiguate if
29547 (Analyze_Selected_Component): Do not generate an actual subtype for the
29548 selected component if expansion is disabled. The actual subtype is only
29549 needed for constraint checks.
29550 (Analyze_Allocator): If restriction No_Streams is set, then do
29551 not permit objects to be declared of a stream type, or of a
29552 composite type containing a stream.
29554 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29555 No_Streams no longer prohibits with'ing this package.
29557 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29558 discriminants, but the parent base has unknown discriminants, there is
29559 no discriminant constraint to inherit. Such a discrepancy can arise
29560 when the actual for a formal type with unknown discriminants is a
29561 similar private type whose full view has discriminants.
29562 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29563 do not permit objects to be declared of a stream type, or of a
29564 composite type containing a stream.
29566 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29568 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29569 protected operations.
29571 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29572 generated name, it complicates decoding in gdb and hinders debugging
29573 of protected operations.
29574 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29575 flag for the protected entry barrier function.
29576 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29577 flag for the protected entry function.
29579 2004-11-18 Nicolas Setton <setton@adacore.com>
29581 * expect.c: Define __unix__ when __APPLE__ is defined.
29583 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29584 Darwin-specific section.
29586 * lang-specs.h: Change the placement of the %1 marker.
29587 Works around the fact that gcc adds -fPIC by default under Darwin.
29589 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29591 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29592 type of the object with the packed array type, set the Analyzed flag
29593 on the object if it is an entity or simple indexed component, to avoid
29594 spurious type errors.
29596 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29598 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29599 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29600 separate line from the version message.
29602 2004-11-18 Ed Falis <falis@adacore.com>
29604 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29606 (init_float): Eliminate initialization of floating point status for
29607 AE653. The instructions have no effect for vThreads.
29609 2004-11-18 Vincent Celier <celier@adacore.com>
29611 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29612 gnatbind is invoked with -shared.
29614 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29616 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29617 for Detect_Blocking which is redundant with the check done within the
29618 procedure Protected_Single_Entry_Call.
29619 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29620 Detect_Blocking which is redundant with the check done within the
29621 procedure Protected_Single_Entry_Call.
29623 2004-11-18 Vincent Celier <celier@adacore.com>
29625 * makegpr.adb (Compile): Put the compiling switches (in package
29626 Compiler and on the command line) immediately after "-c", instead of
29627 at the end of the command line invocation of the compiler, when
29628 compiling a non-Ada file.
29629 (Build_Global_Archive): When there is no need to rebuild the archive,
29630 set Global_Archive_Exists, so that the archive is passed to the linker
29633 2004-11-18 Robert Dewar <dewar@adacore.com>
29634 Sergey Rybin <rybin@adacore.com>
29637 Remove extra paren check from list of checks for redundant constructs
29638 Add documentation of new -gnatyx style check (check extra parens)
29639 Remove paragraph about gnatelim debug options.
29641 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29642 objects rather than forbidding dependencies on the package Ada.Streams.
29644 * sinfo.ads: Add ??? note that we should document pragmas passed to
29647 * g-expect.ads: Fix a few typos in the comments.
29649 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29651 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29654 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29656 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29658 2004-11-07 Andreas Schwab <schwab@suse.de>
29660 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29662 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29665 * Makefile.in (darwin): Set soext to .dylib.
29667 2004-10-26 Vincent Celier <celier@gnat.com>
29668 Thomas Quinot <quinot@act-europe.fr>
29670 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29671 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29672 there is no use of GNAT.Sockets.Constants.
29673 Remove remaining pragma Import for C_Write
29674 Remove C_Read and C_Write from internal implementation unit
29675 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29676 the read and write functions from the system runtime library is fine
29677 on UNIX but won't work under Windows).
29679 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29680 (Check_Selector): Use C_Recv instead of C_Read.
29681 Selectors are the GNAT.Sockets abstraction to perform a select()
29682 call on a set of descriptors. To allow abortion of an ongoing
29683 select operation, some data is written to a dedicated socket that
29684 is always monitored.
29685 Under Windows, the write and read library functions cannot operate
29686 on sockets, so we need to use send and recv instead, which is portable
29687 across all supported platforms.
29689 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29690 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29691 (using the read and write functions from the system runtime library is
29692 fine on UNIX but won't work under Windows).
29694 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29696 * mlib-tgt-darwin.adb: New file.
29698 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29699 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29700 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29701 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29704 * Makefile.in: Add support for building shared libraries under Darwin.
29705 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29706 the low level EH init subprogram to be called from __gnat_initialize.
29708 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29709 indicates which options to pass to the archive indexer.
29711 * mlib-utl.adb: Add support for calling ranlib with additional
29712 options. This is needed for instance under Mac OS X.
29713 (Ranlib_Options): New global variable, used to store the potential
29714 options to pass to ranlib.
29715 (Ar): Use Ranlib_Options when spawning ranlib.
29716 (Initialize): Set the value of ranlib option.
29718 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29720 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29721 instead of 8K, to reflect the real potential needs for stack-checking
29724 2004-10-26 Pascal Obry <obry@gnat.com>
29726 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29728 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29729 Windows only the initial thread stack size can be set so it is good to
29730 start we a low stack size.
29731 The OS will adjust the size as needed.
29733 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29734 Nicolas Setton <setton@act-europe.fr>
29736 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29737 "__unix__" instead of "unix".
29738 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29739 sections were just mistakenly ignored. The former is
29740 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29741 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29742 of hpux. This prevents an unwanted definition of the symbol
29743 convert_addresses in adaint.o.
29745 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29747 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29748 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29750 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29752 * a-filico.ads, a-filico.adb: fix incorrect header.
29754 2004-10-26 Javier Miranda <miranda@gnat.com>
29756 * a-ststio.ads: Fix typo in identifier

29760 * sem_ch4.adb: Minor reformatting.
29762 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29764 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29765 enabled, check the result of unary and binary operations when the
29766 expression is the right-hand side of an assignment.
29768 2004-10-26 Vincent Celier <celier@gnat.com>
29770 * clean.adb (Delete): Do not output warnings when in quiet output and
29771 not in verbose mode.
29772 (Force_Deletions): New Boolean flag, defaulted to False
29773 (Delete): Only delete a file if it is writable, and when
29774 Force_Deletions is True.
29775 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29776 (Usage): Line for new switch -f
29777 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29780 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29782 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29783 JM type only if its size matches that of the wrapper. When a size is
29784 prescribed and the field is not aliased, remove the wrapper of a JM
29785 type only if the size is not greater than that of the packed array.
29786 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29789 2004-10-26 Geert Bosch <bosch@gnat.com>
29791 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29792 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29793 (Pred): Implement in terms of Succ.
29795 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29797 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29798 unchecked conversion is safe for in-place use if the expression of the
29799 conversion is safe.
29800 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29801 be expandable in place even if the aggregate does not come from source.
29802 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29803 designated object of an allocator in place, rather than building it
29804 first on the stack. The previous scheme forces a full copy of the array,
29805 and may be altogether unsusable if the size of the array is too large
29806 for stack allocation.
29808 2004-10-26 Robert Dewar <dewar@gnat.com>
29810 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29811 compares if the component is atomic.
29813 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29814 array assignment if the component type is atomic.
29816 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29817 Eric Botcazou <ebotcazou@act-europe.fr>
29819 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29820 is aliased and is a by_reference type, do not pass by copy.
29821 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29822 detect whether the call is in the right side of an assignment or
29823 the expression of an object declaration. Recurse on component
29824 association within aggregates.
29825 Call it in the condition that determines whether the temporary is
29826 necessary for correct stack-checking.
29828 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29830 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29831 RACW_Type, used in the PolyORB version.
29832 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29833 version and the GARLIC version.
29835 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29836 Rename RCI_Info to RCI_Locator for better consistency between the
29837 GARLIC and PolyORB versions of the distributed systems annex.
29838 (DSA_Implementation_Name): This enumeration lists the possible
29839 implementations of the Partition Communication Subsystem for the
29840 Distributed Systems Annex (DSA). The three available implementations
29841 are the dummy stub implementation (No_DSA), and two versions based on
29842 two different distribution runtime libraries: GARLIC and PolyORB. Both
29843 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29845 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29848 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29849 between the GARLIC and PolyORB versions of the distributed systems
29851 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29853 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29855 * gnat1drv.adb: Suppress calling the back end when
29856 Frontend_Layout_On_Target is true.
29858 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29860 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29861 Set_Read_Only): New subprograms.
29862 These new routines allow the user to set or unset the Owner execute
29863 and Owner write permission flags on a file.
29865 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29866 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29868 2004-10-26 Matthew Gingell <gingell@gnat.com>
29870 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29872 2004-10-26 Pascal Obry <obry@gnat.com>
29874 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29875 memory before the faulting page we properly test the process read
29876 access for this address using appropriate Win32 routine.
29877 (HPUX sections): guard with "__hpux__" instead of "hpux".
29879 2004-10-26 Robert Dewar <dewar@gnat.com>
29881 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29882 entry parameter if pragma Unreferenced set, since we do not properly
29883 handle the case of multiple parameters.
29885 2004-10-26 Vincent Celier <celier@gnat.com>
29887 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29888 (Ada_Objects_Path.Add): For a library project, add to the object path
29889 the library directory only if there is no object directory or if the
29890 library directory contains ALI files.
29891 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29893 2004-10-26 Vincent Celier <celier@gnat.com>
29895 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29896 extension of library projects.
29898 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29899 path defaults to ".:<prefix>/lib/gnat".
29900 (Parse): For an extending all project, allow direct import of a project
29901 that is virtually extended.
29903 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29904 the specified name is directly imported, return its ID. Otherwise, if
29905 an extension of this project is imported, return the ID of the
29908 2004-10-26 Robert Dewar <dewar@gnat.com>
29910 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
29911 (Sub3): New procedure, used by Scaled_Divide
29912 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
29913 correct more than one instance of failure to propagate carries
29915 (Double_Divide): Handle overflow case of largest negative number
29916 divided by minus one.
29918 * s-arit64.ads (Double_Divide): Document that overflow can occur in
29919 the case of a quotient value out of range.
29922 2004-10-26 Robert Dewar <dewar@gnat.com>
29924 * s-bitops.adb (Bit_Eq): Remove redundant check.
29926 * s-bitops.ads: Minor comment updates
29927 Change some occurrences of Address to System.Address
29929 * s-carsi8.ads: Fix minor cut-and-paste error in comments
29931 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29933 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
29934 accessibility check to prefix that is a protected operation.
29936 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29938 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
29939 empty, post message on stub.
29941 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29942 Javier Miranda <miranda@gnat.com>
29944 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
29945 current instance appears within a unit that is directly in the context
29947 Used to determine whether the body of the instance should be analyzed
29948 immediately after its spec, to make its subprogram bodies available
29949 for front-end inlining.
29950 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
29951 constraint is not allowed on the component type (AARM 12.5.3(3))
29953 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29955 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
29956 'Storage_Pool): enhance, document & limit detection of non-sharable
29959 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
29961 * s-pooglo.ads: Add more documentation now that this pool is properly
29964 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29966 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
29967 or protected type with discriminants, do not constrain the
29968 corresponding record type if the subtype declaration has no
29969 discriminant constraints. This can be the case in source code, or in
29970 the subtype declaration created to rename an actual type within an
29973 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29975 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
29976 different kind of stub (possibly wrong name for file), do not check
29978 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
29979 includes call to some function that returns an unconstrained type, do
29982 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29984 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
29985 appear in the code for the main unit. Dependencies among units in the
29986 context of the main unit are established when those other units are
29987 compiled. Otherwise spurious elaboration constraints can generate
29988 incorrect elaboration circularities.
29990 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29991 Ed Schonberg <schonberg@gnat.com>
29993 * sem_util.adb (Is_Aliased_View): Defend against the case where this
29994 subprogram is called with a parameter that is not an object name. This
29995 situation arises for some cases of illegal code, which is diagnosed
29996 later, and in this case it is wrong to call Is_Aliased, as that might
29997 cause a compiler crash.
29998 (Explain_Limited_Type): Refine previous fix to include
29999 inherited components of derived types, to provide complete information.
30001 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30002 is the prival for a protected object.
30003 It is necessary to mark this entity as a variable, in addition to
30004 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30005 modified to avoid checking the Aliased flag on entities that are not
30006 objects. (Checking that flag for non-objects is erroneous and could
30007 lead to a compiler crash).
30009 2004-10-26 Robert Dewar <dewar@gnat.com>
30011 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30012 X_Frac = 0.5, then we know that the number X must be positive.
30013 (Succ): Remove the same redundant test, and also fix the primary test
30014 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30016 (Decompose): Add fuller comments to spec
30018 2004-10-26 Pascal Obry <obry@gnat.com>
30020 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30021 validity (process must have read access). Set to 0 in all other cases.
30022 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30023 violation on Win32.
30024 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30025 segmentation violation.
30027 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30029 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30030 whose type is a constructed subtype of an aliased object with an
30031 unconstrained nominal subtype, convert the actual to the constructed
30032 subtype before taking its address.
30034 2004-10-26 Vincent Celier <celier@gnat.com>
30036 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30037 (Is_Path_Name_Case_Sensitive): New function
30039 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30040 (Base_Name, Simple_Name, Current_Directory, Compose,
30041 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30044 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30045 Vasiliy Fofanov <fofanov@act-europe.fr>
30046 Vincent Celier <celier@gnat.com>
30048 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30049 "memory management issues" section and document some of the useful
30050 memory pools provided as part of the GNAT library.
30051 Remove "virtual" from declaration of A::method2 in
30052 the simple example of Ada/C++ mixed system.
30053 Library Projects may be virtually extended: their virtual extensions
30054 are not Library Projects.
30055 Added section on extending project hierarchies.
30057 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30059 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30061 (__gnat_portable_spawn): Remove const.
30063 * mingw32.h (MAXPATHLEN): Check for previous definition.
30065 2004-10-17 Matthias Klose <doko@debian.org>
30067 * gnatvsn.ads: Set gnat library version to 4.0.
30069 2004-10-05 Vincent Celier <celier@gnat.com>
30071 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30073 2004-10-04 Laurent Guerby <laurent@guerby.net>
30076 * Makefile.in: Define and use RANLIB_FLAGS.
30078 2004-10-04 Pascal Obry <obry@gnat.com>
30080 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30081 other x86 platforms).
30083 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30085 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30086 in general and triggers stack alignment adjustment for thread entry
30087 points on targets where this is necessary.
30089 2004-10-04 Bernard Banner <banner@gnat.com>
30092 * Makefile.in: Add section for powerpc linux
30093 Add variant i-vxwork-x86.ads
30095 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30097 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30099 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30100 table registration calls when need be. Ensures no reference to the crt
30101 ctors symbol are issued in the SJLJ case, which avoids possible
30102 undefined symbol errors in the case of modules to be statically linked
30105 2004-10-04 Javier Miranda <miranda@gnat.com>
30107 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30108 in-line the code corresponding to subprogram Analyze_Actuals. In
30109 addition, analyze the actuals only in case of subprogram call.
30111 2004-10-04 Ed Falis <falis@gnat.com>
30113 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30115 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30117 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30118 in the documentation.
30120 2004-10-04 Robert Dewar <dewar@gnat.com>
30122 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30124 (Analyze_Block_Statement): Add circuitry to detect following dead code
30125 (Check_Unreachable_Code): Handle case of block exit
30127 2004-10-04 Robert Dewar <dewar@gnat.com>
30129 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30130 (XMatchD): Avoid warning for Logic_Error call
30132 2004-10-04 Robert Dewar <dewar@gnat.com>
30134 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30135 consider expressions buried within a procedure actual to be an actual.
30136 This caused some blowups with uses of packed slices within a procedure
30139 2004-10-04 Robert Dewar <dewar@gnat.com>
30141 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30142 longer need to be initialized to zero.
30143 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30144 initialized to zero.
30146 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30147 considered valid, even if the representation is modular. That's correct
30148 now that we no longer initialize packed modular arrays to zero.
30150 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30151 suffixes. These are now documented as the only cases in which the
30152 debugger ignores outer records.
30153 Previously, the spec allowed arbitrary suffixes for this purpose.
30154 Change name of LJM to JM for packed array pad records
30155 Create separate section on packed array handling, and add a whole new
30156 set of comments to this section describing the situation with packed
30157 modular types and justification requirements depending on endianness.
30159 2004-10-04 Robert Dewar <dewar@gnat.com>
30161 * a-except.adb: Add a comment for last change

30170 * sem_util.ads: Minor comment update
30172 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30174 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30175 Inline_Always when in Configurable_Run_Time mode.
30177 * sem_prag.adb (Process_Convention): If entity is an inherited
30178 subprogram, apply convention to parent subprogram if in same scope.
30179 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30180 when in Configurable_Run_Time mode.
30182 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30184 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30185 class_wide type after component list has been inherited.
30187 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30189 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30190 Denotes_Previous_Actual, to handle properly the case of a private
30191 actual that is also the component type of a subsequent array actual.
30192 The visibility status of the first actual is not affected when the
30193 second is installed.
30194 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30195 make fully recursive the treatment of formals of packages declared
30197 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30198 the above on exit from an instantiation.
30199 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30200 current instantiation which is now complete.
30201 (Analyze_Package_Instantiation): No instantiated body is needed if the
30202 main unit is generic. Efficient, and avoid anomalies when a instance
30203 appears in a package accessed through rtsfind.
30205 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30207 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30208 do not generate a declaration for a temporary if the call is part of a
30209 library-level instantiation.
30211 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30213 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30214 searching for a limited component to flag.
30216 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30217 expansion of Input, to account for the fact that the implicit call
30218 generated by the attribute reference must freeze the user-defined
30219 stream subprogram. This is only relevant to 'Input, because it can
30220 appear in an object declaration, prior to the body of the subprogram.
30222 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30223 expansion can proceed and further errors uncovered.
30224 (Minor clean up): Fix cases of using | instead of \ for continuation
30227 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

30231 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30232 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30233 Use gcc_assert and gcc_unreachable.
30235 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30236 specified alignment before validating size.
30237 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30238 stripped-down declaration for the type of the inner field when making
30241 * utils.c (finish_record_type): Do not compute the size in units
30242 incrementally. Instead compute it once for the rep clause case.
30243 Use gcc_assert and gcc_unreachable.
30245 2004-10-04 Vincent Celier <celier@gnat.com>
30247 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30249 (Is_Valid_Path_Name): Take '/' as a directory separator.
30251 2004-10-04 Vincent Celier <celier@gnat.com>
30253 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30254 (Extended_Project) only if Extended_Project is defined, to avoid
30256 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30258 (Parse_Single_Project): Ditto.
30260 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30261 Add_To_Project_Path for virtual projects.
30263 2004-10-04 Vincent Celier <celier@gnat.com>

30268 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30269 parameter Options_2.
30271 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30272 Build_Dynamic_Library with an empty Options_2.
30274 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30277 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30278 directory separator, if any.
30279 (Gprmake): Do not allow mains on the command line for library projects.
30280 Do not attempt to link when the project is a library project.
30281 (Library_Opts): New table to store Library_Options.
30282 (Build_Library): If Library_Options is specified, pass these options
30283 when building a shared library.
30285 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30287 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30288 the end of this procedure now that the unlock operation was inserted
30291 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30293 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30294 corresponding to the Preallocated_Stacks flags in System.
30295 (Get_Target_Parameters): Including the processing for

30307 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30308 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30309 used to signal whether the compiler creates the required stacks and
30310 descriptors for the different tasks (when True) or it is done by the
30311 underlying operating system at run time (when False).
30312 It is initially set to False in all targets.
30314 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30315 if it is supported by the target.
30316 (Make_Task_Create_Call): Pass the stack address if it has been
30317 previously created. Otherwise pass a Null_Address.
30319 * snames.adb: Add _stack.
30321 * snames.ads: Add Name_uStack. Required to allow the expander to
30322 statically allocated task stacks.
30324 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30325 Stack_Address argument.
30326 Check that its value is equal to Null_Address because this target does
30327 not support the static stack allocation.

30336 * exp_dist.adb: Split declaration of asynchronous flag out of
30337 Add_RACW_Read_Attribute.
30338 Minor reformatting for better alignment with PolyORB version.
30339 Store the entity for the asynchronous flag of an RACW, rather than the
30340 expression, in the asynchronous flags table. This will allow this flag
30341 to be used in other subprograms beside Add_RACW_Read_Attribute.
30343 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30345 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30349 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30350 sockets constant MSG_NOSIGNAL (Linux-specific).
30351 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30352 all Send operations.
30353 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30354 from trigerring SIGPIPE.
30355 Rename components to avoid clash with Ada 2005 possible reserved
30357 (Check_Selector): When the select system call returns with an error
30358 condition, propagate Socket_Error to the caller.

30370 Change "pragma inline" to "pragma Inline" in information and error
30372 Minor reformatting.
30374 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30375 right way of doing things after all.
30376 (Freeze_Entity): For object, set Is_Public for imported entities
30377 unless there is an address clause present.
30379 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30381 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30382 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30383 ensures proper handling of types with rep clauses, which might have
30384 their TYPE_SIZE set already.
30386 2004-09-21 Robert Dewar <dewar@gnat.com>
30388 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30389 packed array types in both little- and big-endian cases. This change
30390 ensures that we no longer count on the unused bits being initialized
30391 for such types (and in particular ensures that equality testing will
30392 only read the relevant bits).
30393 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30394 These changes mean that we no longer need to initialize small packed
30396 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30397 optimization to an LJM field as to its parent field.
30399 * ada-tree.h, trans.c, utils.c, utils2.c:
30400 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30402 2004-09-20 Jan Hubicka <jh@suse.cz>
30404 * utils.c (gnat_finalize): Remove.
30405 (end_subprog_body): Directly call cgraph_finalize_function;
30406 do not lower the nested functions.
30408 2004-09-20 Robert Dewar <dewar@gnat.com>
30411 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30412 if an address clause is present, since that means that the Import

30420 Zack Weinberg <zack@codesourcery.com>
30422 * ada-tree.def: Use tree_code_class enumeration constants
30423 instead of code letters.

30441 an existing directory.
30442 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30443 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30444 Convert the result to File_Size.
30446 * prj.ads: (Project_Error): New exception
30448 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30449 Prj.Com, not from Osint.
30450 (Attrs, Package_Attributes): Tables moved to private part of spec
30451 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30453 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30454 Prj.Project_Error after call to Fail.
30455 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30456 Fail. Check that package name is not already in use.
30458 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30459 used by tools, not only by the project manager, and to indicate that
30460 exception Prj.Prj_Error may be raised in case of problem.
30461 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30463 (Attrs, Package_Attributes): Table instantiations moved from the body to
30464 the private part to be accessible from Prj.Attr.PM body.
30466 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30467 from new package Prj.Attr.PM.
30468 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30471 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
30473 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
30474 instead of Elaboration_Checks).

30519 pragmas recognized by GNAT.
30521 * gnat_rm.texi: Document pragma Detect_Blocking.
30523 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
30524 raise Program_Error if called from a protected operation.
30526 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30527 the protected action nesting level.
30528 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30529 protected action nesting level.
30530 (Unlock): When pragma Detect_Blocking is active decrease the protected
30531 action nesting level.
30533 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30534 Protected_Action_Nesting.
30536 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30537 Common_ATCB record. It contains the dynamic level of protected action
30538 nesting for each task. It is needed for checking whether potentially
30539 blocking operations are called from protected operations.
30540 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30541 Detect_Blocking is active or not in the partition.
30543 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
30544 raise Program_Error if called from a protected operation.

30571 active, raise Program_Error if called from a protected operation.
30572 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
30573 protected action nesting level.
30575 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30576 insertion of the statement raising Program_Error. The run time
30577 contains the required machinery for handling that.
30579 * sem_util.ads: Change comment associated to procedure
30580 Check_Potentially_Blocking_Operation.
30581 This procedure does not insert a call for raising the exception because
30582 that is currently done by the run time.
30584 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30586 * init.c: Add the global variable __gl_detect_blocking that indicates
30587 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30588 making the pragma available at run time.
30589 (__gnat_set_globals): Pass and update the detect_blocking parameter.
30591 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
30592 pragma Detect_Blocking is active.
30594 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30596 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30597 DB is found in the ali file. Any unit compiled with pragma
30598 Detect_Blocking active forces its effect in the whole partition.
30600 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30601 Detect_Blocking is active and delay is called from a protected
30604 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30605 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30606 Detect_Blocking is active (0 otherwise).
30607 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30608 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
30611 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
30613 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30614 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30617 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30618 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30619 Update API in placeholder implemetation of s-parint to reflect changes
30620 in distribution runtime library.
30622 * sem_ch3.adb (Expand_Derived_Record): Rename to
30623 Expand_Record_Extension.
30625 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30626 primitive operations of potentially distributed object types that have
30627 non-controlling anonymous access formals.
30629 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30631 New implementation of expansion for remote access-to-subprogram types,
30632 based on the RACW infrastructure.
30633 This version of sem_dist is compatible with PolyORB/DSA as well as
30636 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30637 Asynchrronous that applies to a remote access-to-subprogram type, mark
30638 the underlying RACW type as asynchronous.
30640 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30641 __gnat_using_gnu_linker to 1.
30643 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30644 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
30645 GNAT.Perfect_Hash_Generators, and remove the empty

30650 * exp_ch3.adb (Expand_Derived_Record): Rename to
30651 Expand_Record_Extension.
30652 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30653 a component declaration must remain attached at that point in the
30654 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30655 It is therefore necessary to take a copy of the expression when building
30656 the corresponding assignment statement in the init proc.
30657 As a side effect, in the case of a derived record type, we now see the
30658 original expression, without any rewriting that could have occurred
30659 during expansion of the ancestor type's init proc, and we do not need
30660 to go back to Original_Node.
30662 * exp_ch3.ads (Expand_Derived_Record): Rename to
30663 Expand_Record_Extension.
30665 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
30666 Returns the RACW type used to implement a remote access-to-subprogram
30668 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
30669 New subprograms. Used to create a proxy tagged object for a remote
30670 subprogram. The proxy object is used as the designated object
30671 for RAS values on the same partition (unless All_Calls_Remote applies).
30672 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30673 System.Partition_Interface.Get_Unique_Remote_Pointer.
30674 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30675 Renamed from Add_RAS_*_Attribute.
30676 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
30678 New implementation of expansion for remote access-to-subprogram types,
30679 based on the RACW infrastructure.
30681 * exp_dist.ads (Copy_Specification): Update comment to note that this
30682 function can copy the specification from either a subprogram
30683 specification or an access-to-subprogram type definition.
30685 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30687 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30688 in an instance, between an explicit subprogram an one inherited from a
30689 type derived from an actual.
30691 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30692 add a polling call if the subprogram is to be inlined by the back-end,
30693 to avoid repeated calls with multiple inlinings.
30695 * checks.adb (Apply_Alignment_Check): If the expression in the address
30696 clause is a call whose name is not a static entity (e.g. a dispatching
30697 call), treat as dynamic.
30699 2004-09-09 Robert Dewar <dewar@gnat.com>
30701 * g-trasym.ads: Minor reformatting
30703 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

30709 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
30712 2004-09-09 Pascal Obry <obry@gnat.com>
30714 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30715 enable map file generation. Add the right option to generate the map
30716 file if Map_File is set to True.
30718 * gnatdll.adb (Gen_Map_File): New variable.
30719 (Syntax): Add info about new -m (Map_File) option.
30720 (Parse_Command_Line): Add support for -m option.
30721 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

30742 * opt.ads: Add Ada_Version_Runtime constant used to decide which
30743 version of the language is used to compile the run time.
30745 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
30747 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
30748 of variable length temporaries for function return now that the
30749 back-end and gigi support it.
30751 2004-09-01 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30753 * misc.c (gnat_print_type): Use TYPE_RM_SIZE_NUM.

30973 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
30974 discriminants that rename those of the parent, recover names of

31006 returning C.int, to avoid using a derived boolean type.
31008 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

31037 ignore overflows on low and high bounds of an index to also account for
31038 differences in signedness between sizetype and gnu_index_subtype.

34956 complete assignment subtree which is now unnecessary, as the expansion
34957 of inlined call has been improved to preserve a consistent assignment

34959 after checks have been applied, or else unnecessary checks will

35141 the null-excluding type to force the corresponding run-time check.
35143 * exp_ch6.adb (Expand_Call): Do not generate the run-time check in
35144 case of access types unless they have the null-excluding attribute.

35153 part has been scanned-out and it was present
35155 * par-ch3.adb, par-ch4.adb, par-ch6.adb: Give support to AI-231
35157 * sem_aggr.adb: (Check_Can_Never_Be_Null): New subprogram
35158 (Aggregate_Constraint_Checks): Generate conversion to the null-excluding
35159 type to force the corresponding run-time check
35160 (Resolve_Aggregate): Propagate the null-excluding attribute to the array
35162 (Resolve_Array_Aggregate): Carry out some static checks
35163 (Resolve_Record_Aggregate.Get_Value): Carry out some static check
35165 * sem_ch3.adb (Access_Definition): In Ada 0Y the Can_Never_Be_Null
35166 attribute must be set only if specified by means of the null-excluding

35183 (Set_Actual_Subtypes): Generate null-excluding subtype if the
35184 null-excluding part was present; it is not required to be done here in
35185 case of anonymous access types.
35186 (Set_Formal_Mode): Ada 0Y allows anonymous access to have the null
35189 * sem_res.adb (Resolve_Actuals): Carry out some static check
35190 (Resolve_Null): Allow null in anonymous access
35192 * sinfo.adb: New subprogram Null_Exclusion_Present
35193 All_Present and Constant_Present available on access_definition nodes
35195 * sinfo.ads: New flag Null_Exclusion_Present on subtype_declaration,
35196 object_declaration, derived_type_definition, component_definition,

35216 * sem_ch12.adb: Add comment for previous change
35218 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
35220 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35221 executable name when not initialized. Otherwise, use its current value.
35223 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35224 initialize it to another executable name than the current one. This
35225 allows to configure paths for an executable name (gnatmake) different
35226 from the current one (gnatdist).
35228 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35230 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35231 current unit cannot be inlined if it appears in the body of a withed
35232 unit, to avoid order of elaboration problems in gigi.
35234 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35235 information for protected (wrapper) operation as well, to simplify gdb
35238 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35239 protected body, indicate that the entity for the generated spec comes
35240 from source, to ensure that references are properly generated for it.
35241 (Build_Body_To_Inline): Do not inline a function that returns a
35244 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
35245 apply convention to homonyms that are declared explicitly.
35247 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
35248 that renames an equality operator and the operands are overloaded,
35249 resolve them with the declared formal types, before rewriting as an
35252 2004-03-29 GNAT Script <nobody@gnat.com>
35254 * Make-lang.in: Makefile automatically updated
35256 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
35258 * memtrack.adb: Log realloc calls, which are treated as free followed
35261 2004-03-25 Vincent Celier <celier@gnat.com>
35263 * prj-makr.adb (Process_Directories): Detect when a file contains
35264 several units. Do not include such files in the config pragmas or

35275 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35277 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35278 attribute reference does not denote a subtype, it can be any
35279 expression that has a classwide type, potentially after an implicit
35280 dereference. In particular, the prefix can be a view conversion for
35281 a classwide type (for which Is_Object_Reference holds), but it can
35282 also be a value conversion for an access-to-classwide type. In the
35283 latter case, there is an implicit dereference, and the original node
35284 for the prefix does not verify Is_Object_Reference.
35286 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35287 conversion of a discriminant-dependent component of a mutable object
35290 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35292 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35293 inherited, has convention C, and has unconstrained array parameters,
35294 place the corresponding warning on the derived type declaration rather
35295 than the original subprogram.
35297 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35298 indication on renaming declaration, if formal has a box and actual
35301 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35302 determine whether to generate an implicit or explicit reference to
35303 the renamed entity.
35305 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35306 subprogram renaming comes from a defaulted formal subprogram in an
35309 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35311 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35312 value expressions to ensure that calls within a component definition
35313 will be checked (since those are evaluated during the record type's
35316 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
35318 * s-tpobop.adb: Code clean up:
35319 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

35364 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35365 declaration for a child subprogram body that acts as a spec, indicate
35366 that the entity in the declaration needs debugging information.
35368 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35369 full view if the subtype is created for a constrained record component;
35370 gigi has enough information to construct the record, and there is no
35371 place in the tree for the declaration.
35373 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35374 serial number for the dummy body that is built for analysis, to avoid
35375 inconsistencies in the generation of internal names when compiling
35378 2004-03-22 Thomas Quinot <quinot@act-europe.fr>

35406 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
35407 gnat_ug_wnt.texi: Regenerate.
35409 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
35411 * ada-tree.h: Update copyright notice.
35412 Minor reformatting.
35414 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35416 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35417 as regular exception objects and not as mere integers representing the
35418 condition code. The latter approach required some dynamics to mask off
35419 severity bits, which did not fit well into the GCC table based model.
35420 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35421 exception data objects. We don't it and it would conflict with the other
35422 external symbol we have to generate for such exceptions.
35424 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35425 the special code for VMS exceptions, since these are now represented
35426 as regular exceptions objects.
35428 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35430 * decl.c (debug_no_type_hash): Remove.

35432 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
35434 2004-03-19 Laurent Guerby <laurent@guerby.net>
35436 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35437 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35439 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35441 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35442 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35443 (TYPE_RM_SIZE_INT): Directly use type.values.
35444 (TREE_LOOP_ID): Clean up check.
35445 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35446 TYPE_VALUES, not TYPE_FIELDS.
35447 * trans.c (convert_with_check): Delay access of bounds of basetype
35448 until sure is numeric.

35455 * 5ataprop.adb, 5ftaprop.adb, 5htaprop.adb, 5itaprop.adb, 5staprop.adb,
35456 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
35457 Specific.Set instead of direct call to e.g pthread_setspecific.
35459 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35461 * adaint.c: Update comments.
35463 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35464 GNATLIB_SHARED for FreeBSD.
35466 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35468 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35469 When needed (stack checking) the stack size is retrieved
35470 from the VxWorks kernel.
35472 * Makefile.in: Flag -nostdinc is required when building the run time
35473 for avoiding looking for files in the base compiler.
35474 Add the VxWorks specific version of the package body for
35475 System.Stack_checking.Operations (5zstchop.adb).
35477 * Make-lang.in: Add the object file for
35478 System.Stack_Checking.Operations.
35480 * Makefile.rtl: Add object file for the package
35481 System.Stack_Checking.Operations.
35483 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
35485 * s-stache.ads, s-stache.adb: Move the operations related to stack
35486 checking from this package to package System.Stack_Checking.Operations.
35487 This way, stack checking operations are only linked in the final
35488 executable when using the -fstack-check flag.
35490 2004-03-18 Doug Rupp <rupp@gnat.com>
35492 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
35495 * 5qsystem.ads, 5xcrtl.ads: New files.

35501 * prj-env.adb (Source_Paths, Object_Paths): New tables.
35502 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35503 the procedures Add_To_Path_File.
35504 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35505 making sure that each directory is present only once and, for object
35506 dirs, when a directory already present is added, the duplicate is
35507 removed and the directory is always put as the last in the table.
35508 Write the path files at the end of these accumulations.
35510 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35511 Files_Htable for all sources.
35513 * prj-proc.adb (Process): Remove restrictions between not directly
35514 related extending projects.

35522 parameter Trusted_Mode.
35524 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35526 * scn.adb (Determine_License): Take into account a degenerated case
35527 when the source contains only comments.
35529 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35531 * sem_warn.adb (Check_References): For a warning on a selected
35532 component that does not come from source, locate an uninitialized
35533 component of the record type to produce a more precise error message.
35535 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35537 * 3zsoccon.ads: Fix multicast options.
35539 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35542 2004-03-15 Robert Dewar <dewar@gnat.com>
35544 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
35545 pragma used for a private type.
35547 * lib-xref.adb (Generate_Reference): Do not generate warning if
35548 reference is in a different unit from the pragma Unreferenced.
35550 * 5vtpopde.adb: Minor reformatting
35551 Fix casing of To_Task_ID
35553 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35554 flag if we have an unchecked conversion to an access type in the same
35557 2004-03-15 Geert Bosch <bosch@gnat.com>
35559 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35560 imaginary parts, use Double precision throughout.
35562 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35563 we want to be able to compile run-time with -gnata for testing, but
35564 this may also be instantiated in user code that is compiled with -gnata.
35566 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35568 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35569 codes. Having a separate type for this is useful to enforce consistency
35570 throughout the various run-time units.
35571 (Exception_Data): Use Exception_Code for Import_Code.
35573 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
35574 Natural and Integer in various places.
35575 (Register_VMS_Exception): Use Base_Code_In to compute the exception code
35576 with the severity bits masked off.
35577 (Register_VMS_Exception): Handle the additional exception data pointer
35580 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
35581 component, now reflected by an exported accessor.
35582 (is_handled_by): New routine to compute whether the propagated
35583 occurrence matches some handler choice specification. Extracted out of
35584 get_action_description_for, and expanded to take care of the VMS
35586 (get_action_description_for): Use is_handled_by instead of an explicit
35587 complex condition to decide if the current choice at hand catches the
35588 propagated occurrence.
35590 * raise.h (Exception_Code): New type for C.
35592 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35593 System.Standard_Library.Exception_Code, to allow references from the
35594 pragma import/export expander.
35596 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35597 New accessors to allow easy access to GNAT exception data
35599 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35600 redundant Handled_By_Others component, helper for the personality
35601 routine which will now be able to call the appropriate exception data
35604 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35605 component of Standard_Exception_Type to be the closest possible to
35606 Exception_Code in System.Standard_Library, that we cannot get at this
35607 point. Expand a ??? comment to notify that this type node should
35608 probably be rewritten later on.
35610 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35611 registration call to include a pointer to the exception object in the
35614 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35615 instead of int and explicit bitmasks.
35617 2004-03-15 Vincent Celier <celier@gnat.com>
35619 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35620 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35622 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35623 longer needed now that it is in the spec of
35624 System.Tasking.Task_Attributes.
35626 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35628 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35630 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35632 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35633 taken care of in Scan_Make_Arg.
35634 (Scan_Make_Arg): Add the executable suffix only if the argument
35635 following -o, in canonical case, does not end with the executable
35636 suffix. When in verbose mode and executable file name does not end
35637 with executable suffix, output the executable name, in canonical case.
35639 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35640 to avoid warnings when instantiating Ada.Task_Attributes.
35643 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35644 in the correct order.
35646 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
35647 redirect standard output and error to a file for the invocation of the
35648 compiler, then read the file.

37071 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37072 N_String_Literal node always references an E_String_Literal_Subtype
37073 entity. This may not be true in the future.
37074 (Possible_Bit_Aligned_Component): Move processing of
37075 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37077 * exp_ch6.adb (Expand_Thread_Body): Pick up

37082 (Type_May_Have_Bit_Aligned_Components): New function.

37122 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37123 ineffective elaborate all pragmas on non-visible packages (this
37124 happened when a renamed subprogram was called). Now the elaborate all
37125 always goes on the package containing the renaming rather than the one
37126 containing the renamed subprogram.
37128 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37129 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37154 * make.adb (Gnatmake): Special process for files to compile/check when
37155 -B is specified. Fail when there are only foreign mains in attribute

37188 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37190 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37191 all attributes, including read-only attribute.

37196 library naming scheme.

37230 checked when limited aggregates are implemented.

37233 pure, emit warning.

37346 to __gnat_map_signal, imported from init.c to support
37347 signal -> exception mappings that depend on the vxWorks version.
37350 Created and exported __gnat_map_signal to support signal -> exception
37351 mapping that is dependent on the VxWorks version.

37384 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37385 bounds of a loop, create a separate block in order to generate proper
37386 cleanup actions to prevent memory leaks.
37388 * sem_res.adb (Resolve_Call): After a call to
37389 Establish_Transient_Scope, the call may be rewritten and relocated, in

37408 2003-12-08 Robert Dewar <dewar@gnat.com>
37410 * 7sintman.adb: Minor reformatting
37412 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37413 standard linker options to get standard libraries linked. We now plan
37414 to provide dummy versions of these libraries to match the appropriate
37415 configurable run-time (e.g. if a library is not needed at all, provide
37416 a dummy empty library).
37418 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37419 options (-L parameters and standard libraries). What we plan to do is
37420 to provide dummy libraries where the libraries are not required.
37422 * gnatbind.adb: Minor comment improvement
37424 2003-12-08 Javier Miranda <miranda@gnat.com>
37426 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

37434 of aggregate with default initialized components.
37435 (Has_Default_Init_Comps): Improve implementation to recursively check
37436 all the present expressions.
37438 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37439 to indicate that the initialization call corresponds to a
37440 default-initialized component of an aggregate.
37441 In case of default initialized aggregate with tasks this parameter is
37442 used to generate a null string (this is just a workaround that must be
37443 improved later). In case of discriminants, this parameter is used to
37444 generate a selected component node that gives access to the discriminant
37447 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37448 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37449 allocated aggregates with default-initialized components.
37451 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37452 the box notation is used in positional aggregates.

37494 Process nodes N_Comment.
37496 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37497 without comments and there are some comments, set the flag
37498 Unkept_Comments to True.
37499 (Scan): If there are comments, set the flag Unkept_Comments to True and
37500 clear the comments.
37501 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
37502 (Next_End_Nodes: New table

37530 Comment_Id and set Token to Tok_Comment when scanning a comment.
37531 (Set_Comment_As_Token): New procedure
37533 * sinput-p.adb: Update Copyright notice
37534 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

37539 * sem_aggr.adb: Add dependence on Exp_Tss package
37540 Correct typo in comment
37541 (Resolve_Aggregate): In case of array aggregates set the estimated
37542 type of the aggregate before calling resolve. This is needed to know
37543 the name of the corresponding IP in case of limited array aggregates.
37544 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37545 in case of default initialized array components.
37547 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

37567 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
37568 they are automatically generated by Make-lang.in and cause nothing but
37569 maintenance troubles.
37571 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
37573 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

37587 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
37588 to ensure that the kernel fills in the interrupted context structure
37589 before calling a signal handler, which is necessary to be able to
37590 unwind past it. Update the copyright notice.
37592 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37594 * a-elchha.ads: New file.
37596 * a-elchha.adb: New default last chance handler. Contents taken from

37679 included in HIE_NONE_TARGET_PAIRS.
37681 2003-12-03 Ed Schonberg <schonberg@gnat.com>
37684 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
37685 is legal in an instance, because legality is cheched in the template.
37688 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
37689 appplied to an unchecked conversion of a formal parameter.
37692 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

37706 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
37707 so that the debugger can reliably access the value of the parameter,
37708 and therefore is able to display the exception name when an exception
37709 breakpoint is reached.

38974 (Freeze_Array_Type): We do not need an initialization routine for types
38975 derived from String or Wide_String. They should be treated the same
38976 as String and Wide_String themselves. This caused problems with the
38977 use of Initialize_Scalars.
38980 (Expand_Assign_Record): Do component-wise assignment of non-byte aligned
38981 composites. This allows use of component clauses that are not byte

39002 2003-10-27 GNAT Script <nobody@gnat.com>
39004 * Make-lang.in: Makefile automatically updated
39006 2003-10-27 Ed Schonberg <schonberg@gnat.com>
39009 (Inline_Instance_Body): Indicate that the save/restore of use_clauses
39010 should not be done in Save/Restore_Scope_Stack, because it is performed
39014 (Save_Scope_Stack, Restore_Scope_Stack): Add parameter to indicate
39015 whether use clauses should be removed/restored.

39043 Removes a trailing space.
39045 2003-10-24 Jose Ruiz <ruiz@act-europe.fr>
39048 Remove the test against being in No_Run_Time_Mode before generating a
39049 call to Register_Tag. It is redundant with the test against the
39050 availability of the function Register_Tag.
39052 2003-10-24 Vincent Celier <celier@gnat.com>
39054 * g-catiio.adb: (Month_Name): Correct spelling of February

39059 project file and, if there are several mains, each of them is a source
39060 of the same project file.
39061 (Gnatmake): When a foreign language is specified in attribute Languages,
39062 no main is specified on the command line and attribute Mains is not
39063 empty, only build the Ada main. If there is no Ada main, just compile
39064 the Ada sources and their closure.
39065 (Gnatmake): If a main is specified on the command line with directory
39066 information, check that the source exists and, if it does, that the path
39067 is the actual path of a source of a project.
39070 (File_Name_Of_Library_Unit_Body): New Boolean parameter Full_Path. When
39071 Full_Path is True, return the full path instead of the simple file name.
39072 (Project_Of): New function
39075 (File_Name_Of_Library_Unit_Body): New Boolean parameter Full_Path,
39076 defaulted to False.

39120 External_Tag attribute definition clauses.
39122 2003-10-23 Ed Schonberg <schonberg@gnat.com>
39125 * exp_dbug.adb (Debug_Renaming_Declaration): For the renaming of a
39126 child unit, generate a fully qualified name to avoid spurious errors
39127 when the context contains renamings of different child units with
39128 the same simple name.
39130 * exp_dbug.ads: Add documentation on name qualification for renamings

41236 2002-01-30 Richard Henderson <rth@redhat.com>
41238 * trans.c (tree_transform) [N_Loop_Statement]: Use
41239 expand_exit_loop_top_cond.

41256 (title page): Remove date.
41257 (general) Add @./@: where approriate, and two spaces after the
41258 full stop at the end of a sentence. Use @samp markup when
41259 referring concrete lexical entities (keywords, attribute names
41260 etc.), and @syntax for ARM grammar elements. Use @r for English

41276 function approach did not work well because of a side effect (the
41277 function call could reallocate the table which was being indexed
41278 using its result). Fixes ada/4851.

41373 * trans.c (tree_transform, case of arithmetic operators): If result
41374 type is private, the gnu_type is the base type of the full view,
41375 given that the full view itself may be a subtype.

41645 2001-12-17 Laurent Pautet <pautet@gnat.com>
41648 Fix comment of Shutdown_Socket and Close_Socket. These functions
41649 should not fail silently because if they are called twice, this
41650 probably means that there is a race condition in the user program.
41651 Anyway, this behaviour is consistent with the rest of this unit.

41806 reference nodes, since this field is used in such nodes.

42992 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
42993 instead of simple checksum.
42994 (CRC_Match): new function.
42995 (CRC_Error): new constant.
42997 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
42998 a CRC now and not a simple checksum. A CRC uses lower-case hex
42999 letters, fixes ambiguity in parsing.
43001 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43002 is what this variable will store.
43004 * bcheck.adb: Change reference to chechsum in comments by CRC.
43005 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43006 rename All_Checksum_Match to All_CRC_Match. Change due to API
43007 renaming since now GNAT does not use a simple checksum but a
43008 CRC using GNAT.CRC32.
43010 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43011 now and not anymore a simple checksum.

43048 Update comments for the CRC.
43050 * types.adb (Hex): Use lowercase for the letter part.
43052 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43053 for a word. This is currently used only for CRC. In previous version,
43054 the checksum was using a representation with all letter being
43055 upper-case. With the new implementation (using CRC) we do not remove
43056 the 32th bit of the CRC, so we can have an upper-case starting letter
43057 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43058 It is ambigous since the CRC was optional and could be followed by
43059 options like EB, EE. So now this routines uses lower-case letter for
43060 the hexadecimal representation. Strange enough only lower case letters
43061 where checked in Scan_ALI (even if this was not a possible case).
43063 * gnatvsn.ads (Library_Version): changed to 3.15a.
43065 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43068 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
43071 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
43072 Add 2001 to copyright notice
43073 (Accumulate_Checksum): Modify to use System.CRC32.
43075 * ali-util.ads: Redo changes of previous revision to continue to use
43076 the word Checksum. Add 2001 to copyright notice.
43078 * ali.adb: Undo some of previous changes, not needed.
43079 Keep the change for lower case letters in the checksum.
43081 * ali.ads: Undo previous change not needed.
43083 * bcheck.adb: Undo most of previous change, not needed.
43084 But do use Checksums_Match for checksum comparison.

43087 But do use Checksums_Match for comparing checksums.
43089 * lib-load.adb: Undo previous change, not needed.
43091 * lib-writ.adb: Undo previous change, not needed.

43113 * sinput-l.adb: Undo previous change, not needed.
43115 * sinput.ads: Undo previous change, not needed. Keep only comment
43116 on new checksum algorithm
