1778 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1779 Orig_Prev to Prev in the case where the actual is N_Function_Call or

8383 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
8384 requeue statement is dispatching. Do not emit an error when the name is

8393 replicated some of the select statements. In case the Expander is
8394 disabled, perform regular analysis.

8396 (Analyze_Requeue): Exclude any interpretations that are not entries when
8397 checking overloaded names in a requeue. Also test type conformance for
8398 matching interpretations rather than requiring subtype conformance at
8399 that point to conform with the RM's resolution rule for requeues.

8435 latest Ada 2005 rules about renaming and 'Access of
8436 discriminant-dependent components.
8437 (Check_Nested_Access): Add handling when there are no enclosing
8438 subprograms (e.g. case of a package body).

8987 * ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
8989 (Xref_Record): Change type for Line, since in the case of a reference to
8990 a predefined entity (as happens for array index types), the line is set
8992 Add support for parsing multiple array index types info, or
8993 multiple inherited interfaces info. This information cannot be stored
8994 in Xref_Entity_Record, which only supports a single instance of Tref_*,
8995 and is therefore stored in the list of references instead. It has a
8996 special treatement later on in tools that use this information.
8998 2007-10-15 Tristan Gingold <gingold@adacore.com>
9000 * debug.adb: Document use of -gnatd.a and -gnatd.I

9006 * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
9007 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
9008 care of access to class-wide interface types plus removal of bizarre
9009 conversion of tagged object to access type (reported by Gary
9010 Dismukes). After this patch there is no need to perform any
9011 additional management on these nodes in Expand_Interface_Actuals.
9013 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9014 that handles use of 'Access and 'Unchecked_Access applied to
9015 actuals covering interface types. Such code is now
9016 centralized in Expand_N_Attribute_Reference.
9018 2007-10-15 Ed Schonberg <schonberg@adacore.com>
9020 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
9021 of tagged types whose ultimate ancestor is a CPP type.
9022 (Freeze_Array_Type): For a packed array type, generate an initialization
9023 procedure if the type is public, to handle properly a client that
9024 specifies Normalize_Scalars.
9026 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9028 * exp_ch9.adb (Actual_Index_Expression): When the expansion occurs

9046 (passing'Unrestricted_Access of nested subprograms to Sort) with use of
9047 the generic Heap_Sort_G, in order to avoid trampolines.

9060 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9061 used by VxWorks targets to have access to task-specific data and be
9062 able to extract the stack boundaries for stack checking.
9063 Use system-vms-ia64.ads on ivms.
9065 * Make-lang.in: Update dependencies.
9067 * sysdep.c (__gnat_get_stack_info): Move to a standalone file

9084 95 reserved word in its name.
9085 (Process_Project_Level_Array_Attributes): Process new attribute
9086 Runtime_Library_Dir.
9088 * prj-part.adb (Parse_Single_Project): Do not check the name of the
9089 config project against the user project names.

9092 not include a dot are always case insensitive.
9093 (Process_Declarative_Items): Ditto
9094 (Process_Project_Tree_Phase_1): Set Success to False in case an error is
9097 * prj-util.adb (Value_Of (In_Array)): When Force_Lower_Case_Index is

9104 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9106 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9107 association for an access component, add an association with null as
9108 the expression. Remove testing for array subtypes and the setting in
9109 that case of Ctyp to the array component type, which prevented proper
9110 inclusion of an association for null-initialized arrays. Collapse
9111 condition that tests for array subtypes into just a test of
9112 Is_Partially_Initialized_Type (which already covers arrays anyway).
9114 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9116 * sem_ch12.adb: Minor code reformatting.
9117 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to

9123 * sem_ch3.adb (Build_Derived_Concurrent_Type): Set the Is_Constrained
9124 flag of derived concurrent types, taking into account the flag setting
9125 on the parent subtype and any new set of discriminants.
9127 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9129 * sem_ch4.adb: Minor code and comment reformatting.
9130 (Analyze_Allocator): When the designated type of an unconstrained
9131 allocator is a record with unknown discriminants or an array with
9132 unknown range bounds, emit a detailed error message depending on the
9133 compilation mode and whether the designated type is limited.

9188 for the GNAT tools gnatbind, gnatlink, gnatmake, gnatchop, gnatname,
9189 gnatxref, gnatfind, gnatls, and gnatclean.

9204 * g-soccon-vms.ads: Fix value of MSG_WAITALL.
9207 Update documentation to note that OpenVMS 8.3 or later must be used
9208 to generate g-soccon-vms.ads.
9210 * atree.adb: Add ??? comment
9212 * exp_util.adb: Minor reformatting.

9262 (gigi): Rename and change type of number_units parameter, change
9263 type of file_info_ptr parameter.
9264 * trans.c (number_files): New global variable.
9265 (gigi): Rename and change type of number_units parameter, change
9266 type of file_info_ptr parameter.
9267 If mapped location support is enabled, create the isomorphic mapping
9268 between source files and line maps.
9269 (Sloc_to_locus): If mapped location support is enabled, translate
9270 source location into mapped location.
9271 (annotate_with_node): Rename into set_expr_location_from_node.
9272 Call set_expr_location instead of annotate_with_locus.
9273 (Pragma_to_gnu): Adjust for above change.

9285 (Applicable_Use): Emit a warning when a package tries to use itself.
9286 (Use_One_Type): Add variable Is_Known_Used. Emit a warning when a type

9288 declared in the current package.
9289 (Spec_Reloaded_For_Body): New subsidiary routine for Use_One_Type.
9291 * a-tasatt.adb, s-osprim-vxworks.adb, g-socthi-mingw.adb,

9297 * a-calend-vms.adb, a-calend.adb:
9298 Add a section on leap seconds control along with two entities used to
9299 enable and disable leap seconds support. The array Leap_Second_Times is
9300 now constant and contains hard time values pre-generated. Remove
9301 all elaboration code used to populate the table of leap seconds.
9304 Add entity Leap_Seconds_Support to the list of global run-time variables
9305 along with a comment on its usage and values.
9306 (Gen_Adainit_Ada): Add code to generate the declaration and import of
9307 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
9308 or one (enabled) depending on the presence of binder switch "-y".
9309 (Gen_Adainit_C): Add code to generate the declaration of external int
9310 __gl_leap_seconds_support. Set is value to zero (disabled) or one

9323 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
9325 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
9326 function which can be called by the debugger to interrupt the tasks of
9327 an Ada application asynchronously, as needed on VxWorks.
9328 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
9330 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,

9334 2007-09-26 Olivier Hainque <hainque@adacore.com>
9336 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
9337 #include <utime.h> and #define GCC_RESOURCE_H before
9338 #include <sys/wait.h>.
9339 Add more protections in __gnat_translate_vms.
9341 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
9342 #include <sys/wait.h>.
9344 2007-09-26 Thomas Quinot <quinot@adacore.com>
9345 Sergey Rybin <rybin@adacore.com>
9347 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
9349 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9352 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9354 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9357 * sem_dist.ads: Minor comment fix
9359 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9361 2007-09-26 Javier Miranda <miranda@adacore.com>
9362 Eric Botcazou <ebotcazou@adacore.com>
9365 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9366 indirection added to the HT_Link component of the TSD. This is required
9367 to statically allocate the TSD.
9370 Minor reordering of the declarations in the private part. Required to
9371 add a level of indirection to the contents of the TSD component HT_Link.
9372 This is required to statically allocate the TSD.
9374 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9375 Is_Statically_Allocated set from constant objects.
9376 Do not make exported constants created by the compiler volatile.
9377 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9380 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9381 before returning them.

9384 public part of the package.
9385 (Make_DT): Move HT_Link component out of the TSD record. For this
9386 purpose Make_DT now declares a separate object that stores the
9387 HT_Link value, and initializes the TSD component with the address
9388 of this new object. The addition of this level of indirection is
9389 required to statically allocate the TSD because the TSD cannot
9390 have variable components.
9391 (Expand_Interface_Conversion): Improve the expanded code.
9392 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9394 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9395 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9396 if we are building static dispatch tables then we must not generate
9397 extra code to register the primitive because the dispatch table will
9398 be built at the end of the library package; otherwise we notify that
9399 we cannot build the static dispatch table.
9401 2007-09-26 Robert Dewar <dewar@adacore.com>
9403 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9408 missing component clause.
9409 (Analyze_Attribute_Definition_Clause, case Address): Apply the special
9410 tests for controlled type overlay to composites with controlled

9418 for thunks associated with interface types.
9420 * einfo.ads: Improve documentatation of Is_Internal
9421 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9422 associated with interface types.
9423 Extensive comment fixes regarding flags that appear in all entities. The
9424 documentation is now consistent for all such flags (there were a number
9425 of errors in the documentation in this regard).
9427 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9429 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9430 of these procedures are passed a function call that already has
9431 build-in-place actuals (testing new flag
9432 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9433 the case where processing continues.
9434 (Expand_Call): If the call is generated from a thunk body then we
9435 propagate the extra actuals associated with the accessibility
9436 level of the access type actuals.
9438 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9439 of each extra formal of a protected operation to reference the
9440 corresponding extra formal of the subprogram denoted by the
9441 operation's Protected_Body_Subprogram.

9452 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9454 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9455 debug variable so that it won't be initialized when pragma
9456 Initialize_Scalars is in effect.
9458 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9460 * freeze.adb (Freeze_Entity): Remove check for preelaborable

9464 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9465 preelaborable initialization of a full view in entity loop.
9466 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9467 its child units are use-visible only if they are visible child units.
9469 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9470 whether an expression can be used within a type declaration that
9471 requires preelaborable init.
9472 (Check_Components): Replace inline code that does partial checking for
9473 preelaborable default expressions with call to
9474 Is_Preelaborable_Expression.
9475 (Has_Preelaborable_Initialization): In the case of a generic actual
9476 subtype, (that is, Is_Generic_Actual is True), return the result of
9477 applying Has_Preelaborable_Initialization to the generic actual's base
9480 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9482 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a

9484 (Is_Leap): Move the routine to the scope of Week_In_Year.
9485 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9486 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9487 avoids calling Time_Of and Split, thus making it more efficent.
9488 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9490 * g-calend.ads (Week_In_Year): Change comment to reflect new
9493 2007-09-26 Emmanuel Briot <briot@adacore.com>

9496 Command_Line): New types
9497 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9498 support for defining how switches can be grouped on a command line (as
9499 is the case for -gnatw... for GNAT), and how simple switches can be
9500 used as aliases for more complex switches (-gnatwa is same as
9502 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9503 (Start, Current_*): New subprograms
9504 Added support for parsing an array of strings in addition to the real
9506 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9507 be moved from the body to the private part of the spec.
9508 (*): All subprograms now have an extra parameter with default value to
9509 specify which parser should be used. For backward compatibility, it
9510 defaults to parsing the command line of the application. They were also
9511 modified to properly handle cases where each of the argument does not
9512 start at index 1 (which is always true for Ada.Command_Line, but not
9513 when processing any Argument_List).
9514 (Free): New subprogram
9515 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9516 Argument): New subprograms
9517 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9518 special characters like ':', '=',... are now handled in a single place,
9519 which makes the code more extensible eventually.
9520 (Getopt, Full_Switch): When the switch was returned as part of the
9521 special character '*', make sure it is prepended by the switch character
9522 ('-' in general), so that the application knows whether "foo" or "-foo"
9523 was specified on the command line.

9527 * g-dirope.adb (Remove_Dir): In case we are removing directories
9528 recursively, make sure that if an exception is raised during the
9529 processing, the current working directory is reset to its initial
9530 value before propagating the exception.
9532 2007-09-26 Vincent Celier <celier@adacore.com>
9534 * gnatbind.adb: If there are several ALI files specified and there is
9535 a main program to bind, the first ALI is expected to contain the main
9536 subprogram and the names of the binder generated files will be derived
9537 from the first ALI file name.
9538 (Gnatbind): Fix insertion character in invocation of Error_Msg
9540 2007-09-26 Vincent Celier <celier@adacore.com>
9542 * gnatcmd.adb (Check_Files): Do not include sources that have been
9543 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9545 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9547 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9548 information about each of its index types, following the type
9549 reference for its component type.
9551 2007-09-26 Vincent Celier <celier@adacore.com>
9553 * make.adb: (Kill): New procedure (__gnat_kill imported)

9564 2007-09-26 Vincent Celier <celier@adacore.com>
9566 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9568 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9569 Replace components Compiler_Min_Options and Binder_Min_Options with
9570 Compiler_Required_Switches and Binder_Required_Switches in record

9575 * prj-attr.adb: New attributes Required_Switches (<language>) in
9576 packages Compiler and Binder.
9578 * prj-nmsc.adb: Major rewrite of the processing of configuration
9579 attributes for gprbuild. No impact on GNAT tools.
9581 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9582 process configuration attributes: this is done in Prj.Nmsc.Check.
9583 (Recursive_Process): Make a full copy of packages inherited from project
9584 being extended, instead of a shallow copy.
9585 (Process_Project_Tree_Phase_1): New procedure
9586 (Process_Project_Tree_Phase_1): New procedure
9587 (Process): Implementation now uses the two new procedures
9589 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9590 from the project config, not the tree config that no longer exists.

9616 ancestor of the derived type, the operations are inherited from the
9617 primary dispatch table of the parent.
9618 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9619 when the context is an explicit type conversion.

9916 Thomas Quinot <quinot@adacore.com>
9918 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
9919 create an abstract subprogram in the case of 'Input. For 'Output we now
9920 create a real spec/body when the type is abstract, since it can
9921 potentially be called.
9922 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9923 body for 'Output when the type is abstract (only the creation of the
9924 body for 'Input is excluded when the type is abstract).
9925 (Stream_Operation_OK): Add an additional condition in the return
9926 statement, so that False will be returned for TTS_Stream_Input if the
9927 associated tagged type is an abstract extension. Add comments for
9929 (Expand_N_Object_Declaration): For the case of a shared passive
9930 variable, insert init proc call only after the shared variable
9931 procedures have been processed, because the IP call needs to undergo
9932 shared passive variable reference expansion, which requires these
9933 procedures to be available (and elaborated).
9935 2007-09-10 Vincent Celier <celier@adacore.com>
9937 * prj-env.ads, prj-env.adb (Create_Mapping_File (Language)): Remove
9938 parameter Runtime_Project.
9940 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9942 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
9943 given a box association, the type of the component is discriminated,
9944 and the value of the discriminant is the discriminant of the enclosing
9945 type, retrieve its value from the aggregate itself, where it must have
9948 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
9949 to remove other spurious ambiguities on arithmetic operations involving
9950 literals and addresses, on systems where Address is a visible integer
9951 type, when the operator is called in functional notation.
9952 (Try_Primitive_Operation): Within an instance, a call in prefixed form
9953 is legal when the types match, even if the operation is currently
9956 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9958 * sem_ch12.adb (Build_Local_Package): A formal package with no
9959 associations is legal if all formals have defaults. It is not
9960 equivalent to a formal declared with a box.
9962 2007-09-10 Sergey Rybin <rybin@adacore.com>

9995 the N_Indexed_Component case.
9996 <N_Indexed_Component>: Fall through to above case.

10071 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10073 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the

10078 (Write_Entity_Flags): Write the status of flag Is_Raised.
10079 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10080 spurious ambiguities when integer literals appear in the context of an
10081 address type that is a visible integer type.
10083 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10084 exceptions never being raised.
10085 (Analyze_Raise_Statement): When analyzing an exception, mark it as being
10088 2007-08-31 Javier Miranda <miranda@adacore.com>

10096 initialization aggregate for the type, generate itype references for
10097 thetypes of its (sub)components, to prevent out-of-scope errors in gigi.
10099 2007-08-31 Gary Dismukes <dismukes@adacore.com>
10101 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10102 library-level package renaming, pass the declaration associated with
10103 the renaming's special debug variable to Qualify_Entity_Names to ensure
10104 that its encoded name is properly qualified.
10106 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10107 occurring in the list of entities to qualify, and do not attempt to
10108 traverse an entity list in that case. Variables associated with
10109 ` library-level package renamings can now occur in the table.
10111 * exp_dbug.ads: Revise documentation of the encoding for renaming
10114 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

10117 access type points to an unconstrained array.
10119 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10121 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
10124 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect
10125 simple redundant qualifications. The check is performed whenever the
10126 expression is a non-overloaded identifier.
10127 (Resolve_Type_Conversion): Enchance the redundant type conversion check
10128 to include loop parameters.
10129 (Valid_Conversion): Avoid generation of spurious error message.

10133 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10134 concatenations of string literals into a single literal, in order to
10135 avoid very deep recursion in the front end, which was causing stack
10138 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10139 string, and the right operand is a string literal (the case of "" &
10140 "..."), optimize by avoiding copying the right operand -- just use the
10141 value of the right operand directly.
10143 * stringt.adb (Store_String_Chars): Optimize by growing the
10144 String_Chars table all at once, rather than appending characters one by
10146 (Write_String_Table_Entry): If the string to be printed is very long,
10147 just print the first few characters, followed by the length. Otherwise,
10148 doing "pn(n)" in the debugger can take an extremely long time.
10150 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10151 Store_String_Char with Store_String_Chars.
10153 2007-08-31 Vincent Celier <celier@adacore.com>

10166 have not been fully analyzed.
10168 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10170 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10171 flag, for effiency. It is called when analyzing arithmetic operators
10172 and also for actuals in calls that are universal_integers. The flag is
10173 set for the predefined type address, and for any type or subtype
10176 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10177 Universal_Integer, when the formal is a descendent of address and the
10178 call appears in user code.
10179 (Analyze_Selected_Component): if the prefix is a private extension, the
10180 tag component is visible.
10182 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an

10231 when compiling for powerpc64-*-linux.
10232 * system-linux-ppc64.ads: New file.
10234 2007-08-22 Krister Walfridsson <cato@df.lth.se>

10239 2007-08-16 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
10241 * misc.c (gnat_type_max_size): Constify.
10243 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10245 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10246 associated with Standard_Debug_Renaming_Type, to be used as the type of
10247 the special variables whose names provide debugger encodings for
10248 renaming declarations.
10250 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10251 (Set_Debug_Renaming_Link): Change to set Node25.
10252 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
10253 (Write_Field25_Name): Add case for E_Variable to output
10254 "Debug_Renaming_Link".
10255 (Write_Field23_Name): Correct the output string for "Limited_View".
10257 * exp_dbug.adb: Add with and use of Tbuild.
10258 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10259 and literal with creation of a variable of type
10260 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10261 and the entity of the renaming declaration.
10262 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10263 part of the name of a variable that has a Debug_Renaming_Link.
10265 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10266 special type to be associated with variables that provide debugger
10267 encodings for renaming declarations.

10270 Ed Schonberg <schonberg@adacore.com>
10271 Javier Miranda <miranda@adacore.com>
10273 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10274 ancestor part given by an aggregate to test for an unchecked conversion,
10275 since this can occur in some cases when the ancestor part is a function
10276 call, and we don't want to fall into the recursive call to this
10277 procedure in that case.
10279 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10280 stream attributes on limited types to account for user-specified
10281 attributes as well as whether Input (resp. Output) becomes available
10282 due to Read (resp. Write) being available for the type. Change Boolean
10283 variable to the more accurate name
10284 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10285 double-"not" predicate at beginning of return statement to more
10286 understandable form.
10288 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10289 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10290 in a block statement and use that as the first statement of the
10291 expanded return rather than incorrectly using the handled sequence as
10292 the first statement.
10294 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10295 operation, generate an explicit freeze node for it rather than
10296 generating extra formals, to ensure that gigi has the proper order of
10297 elaboration for anonymous subtypes in the signature of the subprograms.
10298 (Build_In_Place_Formal): Move assertion to beginning of loop.
10299 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10300 applied to a function call (occurs for some cases of 'Input).
10301 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
10302 applied to a function call (occurs for some cases of 'Input).
10304 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10305 2005, generate an extended return statement enclosing the result object
10308 * freeze.adb (Freeze_Record_Type): Extend the current management of
10309 components that are access type with an allocator as default value: add
10310 missing support to the use of qualified expressions of the
10311 allocator (which also cause freezing of the designated type!)
10312 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10313 dispatching operation, since extra formals may be needed by calls to
10314 build-in-place functions (such as stream 'Input).
10316 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10317 formals for 'Constrained and accessibility level in the case of a
10318 predefined dispatching operation.
10320 * exp_util.adb (Insert_Actions): A protected body is a valid insertion

10326 and entry barriers.
10328 2007-08-16 Javier Miranda <miranda@adacore.com>
10330 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10331 is not really required and can introduce regression with the debugger.
10332 The original problem is fixed with the patch written for checks.adb.
10334 2007-08-16 Thomas Quinot <quinot@adacore.com>
10336 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10347 parameter Including_Non_Switch, defaulted to True. When
10348 Including_Non_Switch is False, options that are not switches and
10349 appear as relative path are not converted to absolute paths.

10401 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10402 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10403 the statement which is being resolved comes from a predefined library
10404 unit, all non-predefined library interpretations are skipped.
10405 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10406 but the "&" is user defined, give an error, because the folding would

10463 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10464 Suppress unmodified in-out parameter warning in some cases
10465 This patch is a also fairly significant change to the way suppressible
10466 checks are handled.
10468 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10469 needed for access to concurrent record types generated by the expander.
10470 (Generate_Range_Check): When generating a temporary to capture the
10471 value of a conversion that requires a range check, set the type of the
10472 temporary before rewriting the node, so that the type is always
10473 properly placed for back-end use.
10474 (Apply_Float_Conversion_Check): Handle case where the conversion is
10476 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10477 for a protected type in order to examine its discriminants.

10484 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10485 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10486 tests optimized out.

10490 that has a specified Associated_Final_Chain, do not go up to the
10492 (Expand_N_Type_Conversion): Test for the case of renamings of access
10493 parameters when deciding whether to apply a run-time accessibility
10495 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10496 aggregate code before allocator, and ahead of declaration for
10497 temporary, to prevent access before elaboration when the allocator is
10498 an actual for an access parameter.
10499 (Expand_N_Type_Conversion): On an access type conversion involving an
10500 access parameter, do not apply an accessibility check when the
10501 operand's original node was an attribute other than 'Access. We now
10502 create access conversions for the expansion of 'Unchecked_Access and
10503 'Unrestricted_Access in certain cases and clearly accessibility should
10504 not be checked for those.
10506 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10507 includes a type conversion of a packed component that has been expanded,
10508 recover the original expression for the object, and use this expression
10509 in the post-call assignment statement, so that the assignment is made
10510 to the object and not to a back-end temporary.
10511 (Freeze_Subprogram): In case of primitives of tagged types not defined
10512 at the library level force generation of code to register the primitive
10513 in the dispatch table. In addition some code reorganization has been
10514 done to leave the implementation clear.
10515 (Expand_Call): When expanding an inherited implicit conversion,
10516 preserve the type of the inherited function after the intrinsic
10517 operation has been expanded.
10519 * exp_ch2.ads, exp_ch2.adb
10520 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10521 of an entry formal appearing in an assignment statement does not assign
10523 (Expand_Current_Value): Instead of calling a routine to determine
10524 whether the prefix of an attribute reference should be optimized or
10525 not, prevent the optimization of such prefixes all together.
10527 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10528 component whose prefix is known to be of an access type is an implicit
10529 dereference and does not assign to the prefix.
10531 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10532 Robert Dewar <dewar@adacore.com>
10534 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10535 itype is visited, make an entry into table to link associated node and
10537 Add comments and correct harmless error in Build_NCT_Hash_Tables
10538 (Array_Aggr_Subtype): Associate each itype created for an index type to
10539 the corresponding range construct, and not to the aggregate itself. to
10540 maintain a one-to-one correspondence between itype and its associated
10541 node, to prevent errors when complex expression is copied.
10542 Fix mishandling of multiple levels of parens
10544 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10545 treatment of limited views uniform for all visible declarations in a
10546 limited_withed package.
10547 (New_Copy_Tree): If hash table is being used and itype is visited,
10548 make an entry into table to link associated node and new itype.
10549 (Resolve_Record_Aggregate): Do not add an others box association for a
10550 discriminated record component that has only discriminants, when there
10551 is a box association for the component itself.
10553 * par-ch4.adb: Fix mishandling of multiple levels of parens
10555 2007-08-14 Robert Dewar <dewar@adacore.com>

10592 to make treatment of limited views uniform for all visible declarations
10593 in a limited_withed package.
10594 Improve warnings for in out parameters
10595 (Set_Related_Interaface/Related_Interface): Allow the use of this
10596 attribute with constants.
10597 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10598 Warn on duplicate pragma Preelaborable_Initialialization
10600 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10601 generation of a freezing node to ensure proper management of null
10602 excluding access types in the backend.
10603 (Create_Extra_Formals): Test base type of the formal when checking for
10604 the need to add an extra accessibility-level formal. Pass the entity E
10605 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10606 originally being done in a couple of cases), to ensure that the
10607 Extra_Formals list gets set on the entity E when the first entity is
10609 (Conforming_Types): Add missing calls to Base_Type to the code that
10610 handles anonymous access types. This is required to handle the
10611 general case because Process_Formals builds internal subtype entities
10612 to handle null-excluding access types.
10613 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10614 functions that need it, even when not marked Requires_Overriding.
10615 Improve warnings for in out parameters
10616 (Analyze_Function_Return): Warn for disallowed null return
10617 Warn on return from procedure with unset out parameter
10618 Ensure consistent use of # in error messages
10619 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10620 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10621 the implicit conversion of the expression done for anonymous access
10622 types. This is required to generate the code of the null excluding
10623 check (if required).
10625 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10626 A formal parameter is never publicly referenceable outside of its body.
10627 (Check_References): For an unreferenced formal parameter in an accept
10628 statement, use the same warning circuitry as for subprogram formal
10630 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10631 Output_Unreferenced_Messages, containing the part of that routine that
10632 is now reused for entry formals as described above.
10633 (Goto_Spec_Entity): New function
10634 (Check_References): Do not give IN OUT warning for dispatching operation
10635 Improve warnings for in out parameters

10645 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10646 (Expand_N_Attribute_Reference): Further unify the handling of the
10647 three forms of access attributes, using common code now for all three
10648 cases. Add a test for the case of applying an access attribute to
10649 an explicit dereference when the context is an access-to-interface
10650 type. In that case we need to apply the conversion to the prefix
10651 of the explicit dereference rather than the prefix of the attribute.
10652 (Attribute_Version, UET_Address): Set entity as internal to ensure
10653 proper dg output of implicit importation.
10654 (Expand_Access_To_Type): Removed.
10655 (Expand_N_Attribute_Reference): Merge the code from the three cases
10656 of access attributes, since the processing is largely identical for
10657 these cases. The substantive fix here is to process the case of a
10658 type name prefix (current instance case) before handling the case
10659 of interface prefixes.

10667 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10668 type that is an anonymous access to controlled object, establish
10669 an associated finalization chain to avoid corrupting the global
10670 finalization list when a dynamically allocated object designated
10671 by such a component is deallocated.
10672 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10673 functions that need it, even when not marked Requires_Overriding.

10678 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10679 Suppress_Initialization pragma for a derived type.
10680 (Is_Variable_Size_Record): New subprogram.
10681 (Build_Offset_To_Top_Functions): New implementation that simplifies the

10684 (Build_Init_Procedure): Improve the generation of code to initialize the
10685 the tag components of secondary dispatch tables.
10686 (Init_Secondary_Tags): New implementation that simplifies the previous

10689 object declaration, for diagnostic purposes.
10690 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10691 diagnose attemps to freeze a subprogram when some untagged type of its
10692 profile is a private type whose full view has not been analyzed yet.
10693 (Freeze_Array_Type): Generate init proc for packed array if either
10694 Initialize or Normalize_Scalars is set.
10695 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10696 constructing the new profile, copy the null_exclusion indicator for each
10697 parameter, to ensure full conformance of the new body with the spec.

10700 Create wrappers for constructor functions that need it, even when not
10701 marked Requires_Overriding.

10711 (Has_Compatible_Type): Remove machinery that skips interpretations if
10712 they are labeled as potentially hidden by an abstract operator.
10713 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10714 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10715 (Write_Overloads): Output the abstract operator if present.

10737 of the same dispatch table slot to renamed primitives.
10738 (Make_Select_Specific_Data_Table): Handle private types.
10739 (Tagged_Kind): Handle private types.
10740 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10741 output of implicit importation and exportation.
10742 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10743 first formal of the thunk is always associated with the controlling
10744 type. In addition perform the following code cleanup: remove formal
10745 Thunk_Alias which is no longer required, cleanup evaluation of the
10746 the controlling type, and update the documentation.
10747 Replace occurrence of Default_Prim_Op_Count by
10748 Max_Predef_Prims. Addition of compile-time check to verify
10749 that the value of Max_Predef_Prims is correct.
10750 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10751 (Make_DT): Add parameter to indicate when type has been frozen by an
10752 object declaration, for diagnostic purposes.
10753 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10754 construction of statically allocated dispatch tables.
10755 (Make_DT): In case of library-level tagged types export the declaration
10756 of the primary tag. Remove generation of tags (now done by Make_Tags).
10757 Additional modifications to handle non-static generation of dispatch
10758 tables. Take care of building tables for asynchronous interface types
10759 (Make_Tags): New subprogram that generates the entities associated with
10760 the primary and secondary tags of Typ and fills the contents of Access_
10761 Disp_Table. In case of library-level tagged types imports the forward
10762 declaration of the primary tag that will be declared later by Make_DT.
10763 (Expand_Interface_Conversion): In case of access types to interfaces
10764 replace an itype declaration by an explicit type declaration to avoid
10765 problems associated with the scope of such itype in transient blocks.

10771 * exp_util.ads, exp_util.adb:
10772 This patch replaces a number of occurrences of explicit tests for N_Null
10773 with calls to Known_Null. This improves tracking of null values, since
10774 Known_Null also catches null constants, and variables currently known to
10775 be null, so we get better tracking.
10776 (Ensure_Defined): create an itype reference only in the scope of the
10778 (Side_Effect_Free): A selected component of an access type that
10779 denotes a component with a rep clause must be treated as not
10780 side-effect free, because if it is part of a linked structure its
10781 value may be affected by a renaming.
10782 (Expand_Subtype_From_Expr): For limited objects initialized with build
10783 in place function calls, do nothing; otherwise we prematurely introduce
10784 an N_Reference node in the expression initializing the object, which
10785 breaks the circuitry that detects and adds the additional arguments to
10786 the called function. Bug found working in the new patch for statically
10787 allocated dispatch tables.
10788 (Is_Library_Level_Tagged_Type): New subprogram.
10789 (Remove_Side_Effects): If the expression of an elementary type is an
10790 operator treat as a function call.
10791 (Make_Literal_Range): If the index type of the array is not integer, use
10792 attributes properly to compute the constraint on the resulting aggregate
10795 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10796 class-wide type whose base type is an incomplete private type, leave
10797 class-wide type unfrozen so that freeze nodes can be generated
10798 properly at a later point.
10799 (Freeze_Entity, array case): Handle case of pragma Pack and component
10800 size attributre clause for same array.

11256 (Analyze_Compilation_Unit): If unit is a subprogram body that has no
11257 separate declaration, remove the unit name from visibility after
11258 compilation, so that environment is clean for subsequent compilations.

11428 (Set_Item): When the new item is an element of the currently allocated
11429 table passed by reference, save a copy on the stack if we're going

11446 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11447 derived type with interface progenitors use the analyzed formal as the
11448 parent of the actual, to create renamings for all the inherited
11449 operations in Derive_Subprograms.
11450 (Collect_Previous_Instances): new procedure within of
11451 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11452 unit being loaded, to ensure that the generation of global symbols is
11453 consistent in different compilation modes.
11454 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11455 takes progenitor types into account.
11456 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11457 traversing over the primitives of the formal and actual types to locate
11458 any abstract subprograms of the actual type that correspond to a
11459 nonabstract subprogram of the formal type's ancestor type(s), and issue
11460 an error if such is found.
11461 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11462 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11463 Remove bogus guard around calls to Inherit_Context.
11464 (Reset_Entity): If the entity is the selector of a selected component
11465 that denotes a named number, propagate constant-folding to the generic
11466 template only if the named number is global to the generic unit.
11467 (Set_Instance_Env): Only reset the compilation switches when compiling
11468 a predefined or internal unit.
11470 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11472 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
11473 parameter to determine whether operation applies to the prefix.
11474 (Complete_Object_Operation): If actual has an access type and
11475 controlling formal is not an in_parameter, reject the actual if it is
11476 an access_to_constant type.
11477 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11478 type, the candidate operations are found in the scope of declaration of
11479 the type, because the type has no primitive subprograms.
11480 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11481 a private extension, only examine visible components before trying to
11482 analyze as a prefixed call.
11483 Change Entity_List to Type_To_Use, for better readability.
11484 (Has_Fixed_Op): Use base type when checking whether the type of an
11485 operator has a user-defined multiplication/division
11486 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
11487 user-defined operators are available for fixed-point types.

11493 formal At_Any_Place indicating, when True, that we want to test for
11494 availability of the stream attribute at any place (as opposed to the
11495 current visibility context only).
11496 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11497 purpose of enforcing E.2.2(8) only if it is not available at any place.
11498 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11499 when checking the legality of an extension aggregate in a preelaborable
11500 package. Treat the literal null as a valid default expression in a
11501 component declaration for a type with preelaborable initialization.
11502 A limited interface is a legal progenitor for the designated type of a
11503 remote access to class-wide type.

11515 mark the full view as referenced, to prevent spurious warnings.
11516 (Find_Selected_Component, Has_Components): Handle properly non-limited
11517 views that are themselves incomplete types.
11518 Handle interfaces visible through limited-with clauses.
11519 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11520 subprogram generic actual for which we have generated a renaming.
11521 Warn when the renaming introduces a homonym of
11522 the renamed entity, and the renamed entity is directly visible.

11530 (Resolve_Allocator): Perform cleanup if resolution has determined that
11531 the allocator is not a coextension.
11532 (Resolve): Skip an interpretation hidden by an abstract operator only
11533 when the type of the interpretation matches that of the context.
11534 (Resolve): When looping through all possible interpretations of a node,
11535 do not consider those that are hidden by abstract operators.
11536 (Resolve_Actuals): When verifying that an access to class-wide object
11537 is an actual for a controlling formal, ignore anonymous access to
11538 subprograms whose return type is an access to class_wide type.
11539 (Resolve_Slice): If the prefix of the slice is a selected component
11540 whose type depends on discriminants, build its actual subtype before
11541 applying range checks on the bounds of the slice.
11542 (Valid_Conversion): In an instance or inlined body, compare root types,
11543 to prevent anomalies between private and public views.
11544 (Resolve): Improve error message for ambiguous fixed multiplication
11545 expressions that involve universal_fixed multiplying operations.

11565 elabration statements, register the package with the name server
11566 at the beginning, not at the end, of the elaboration statements so
11567 that they can create remote access to subprogram values that designate
11568 remote subprograms from the package.

12622 (build_call_alloc_dealloc): When releasing a super-aligned object,
12623 retrieve the system's allocator return value from where build_allocator
12624 has stored it, just ahead of the adjusted address we are passed.

12651 (Gen_Output_File_Ada, Gen_Output_File_C): Never use __attribute
12652 ((destructor)) for adafinal, even when switch -a is used.
12653 Do not issue pragma Linker_Destructor for adafinal when switch -a is
12655 (Gen_Object_Files_Options): Add formatting of Linker Options, when
12656 Output_Linker_Option_List is set. Suppress this formatting when
12657 Zero_Formatting is set.
12658 Add case for CLI_Target.
12659 (System_Restrictions_Used): New flag, used to avoid generating with of
12660 System_Restrictions and initialization of the data unless there is
12661 some use of System.Restrictions in the partition.

12694 (Get_E_Length): Protect against bomb in case scope is standard
12695 (Selected_Range_Checks): If the node to be checked is a conversion to
12696 an unconstrained array type, and the expression is a slice, use the
12697 bounds of the slice to construct the required constraint checks.
12698 Improve NOT NULL error messages
12699 (Apply_Constraint_Check): If the context is a null-excluding access
12700 type, diagnose properly the literal null.

12716 Arnaud Charlet <charlet@adacore.com>
12718 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12719 applicable to types that have the With_Type flag set. Returns the
12720 non-limited view of the type, if available, otherwise the type itself.
12721 For class-wide types, there is no direct link in the tree, so we have
12722 to retrieve the class-wide type of the non-limited view of the Etype.
12723 New attributes Static_Initialization and Static_Elaboration_Desired.
12724 Remove the pragma Thread_Body, and the associated flag
12725 Is_Thread_Body in entities, and all related code.
12726 (Suppress_Value_Tracking_On_Call): New flag
12727 E_Exception has Esize and Alignment fields
12728 (Universal_Aliasing): New function.

12738 (Original_Access_Type): Remove, not needed.
12739 (Root_Type): Handle properly subtypes of class-wide-types.
12742 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12743 class-wide types visible through limited-with clauses.
12744 (Try_Primitive_Operation): When examining all primitive operations of a
12745 tagged type, do not consider subprograms labeled as hidden unless they
12746 belong to a private generic type with a tagged parent.
12747 (Try_Object_Operation): Extensive rewriting, to handle properly various
12748 overloading cases, when several ancestors may have class-wide operations
12749 that are possible candidates, and when the overloaded functions return
12750 array types and have defaulted parameters so that the call may be
12751 interpreted as an indexing.
12752 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12753 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12754 successive actuals before analyzing the call itself.
12755 (Try_Primitive_Operation): A primitive operation is compatible with the
12756 prefix if the prefix has a synchronized type and the type of the formal
12757 is its corresponding record, as can be the case when the primitive
12758 operation is declared outside of the body of the type.
12759 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12760 perform homonym traversal, looking for class-wide operation matches
12761 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12762 access parameters are now restricted to anonymous access types.
12763 (Mark_Allocator): An allocator with a discriminant association parent is
12765 (Try_One_Prefix_Interpretation): If the type of the object is
12766 incomplete, as can be happen when it is a limited view obtained through
12767 a limited_with_clause, the selected component is not part of a prefixed
12769 (Complete_Object_Operation): Diagnose properly an object that is not
12770 aliased when the corresponding controlling formal is an access
12772 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12773 ambiguous calls in prefixed notation, where two primitives differ only
12774 in that the controlling argument of one is an access parameter.
12776 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12777 whether a function that returns an unconstrained type can be inlined.
12778 (Process_Formals): Diagnose properly the illegal use of an incomplete
12779 type in the profile of an access_to_subprogram declaration.
12780 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12781 operations are attached to the corresponding record.
12782 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12783 When processing a primitive of a concurrent type which implements an
12784 interface change the type of all controlling formals to that of the
12785 corresponding record type.
12786 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12787 to determine the tagged type to which a primitive belongs.
12788 (Check_Conventions): Capture condition to ignore a primitive operation
12789 (which is shared between the loop in Check_Conventions and the one in
12790 Check_Convention) in a new local function Skip_Check.
12791 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12792 confusion with Check_Conventions' own Prim_Op local variable.
12793 (Create_Extra_Formals): Test for a tagged result type rather than a
12794 controlling result when determining whether to add a BIP_Alloc_Form
12795 formal and a BIP_Final_List formal to the function.
12796 (Check_Conformance); For parameters that are anonymous access types,
12797 subtype conformance requires that the not null and the constant
12798 indicators must match
12799 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12800 to retrieve the appropriate type when processing a concurrent type
12801 declared within a generic. Minor comment reformatting. Change invocation
12802 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12804 (Analyze_Subprogram_Body): If the return type of a function is an
12805 anonymous access to the limited view of a class-wide type, and the
12806 non-limited view of the type is available, update the type of the
12807 function so that code can be generated.
12808 (Process_Formals): In case of access-subtype itype whose designated
12809 type is also an itype (situation that happens now with access to
12810 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12811 attribute to avoid backend problems.
12812 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12813 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12814 anonymous types' designated types are same before testing
12815 Subtypes_Statically_Match.
12816 (Create_Extra_Formals): Test for a named access parameter that is a
12817 controlling formal as an additional condition for adding an
12818 accessibility level formal. This can occur in the subp type created for
12819 dispatching calls in Expand_Dispatching_Call, and allows calling
12820 Create_Extra_Formals from that procedure rather than special-casing the
12821 extra formals there.
12822 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12823 when the function has a controlling result.
12824 (Check_Returns): Add much more knowledge of the optimization of local
12825 raise statements to gotos, to retain proper warnings in this case.
12826 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12827 nodes when looking for last statement.
12829 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12830 class-wide types visible through limited with clauses.
12831 (Add_One_Interp): If the operands are anonymous access types, the
12832 predefined operator on universal_access is immediately visibles
12833 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12834 other anonymous access types.
12835 (Disambiguate): Take into account CIL convention.
12836 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12838 2007-06-06 Robert Dewar <dewar@adacore.com>
12840 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,

12843 Fix lower bound of tables.
12846 * nlists.adb: Ditto.
12847 (Prev_Node, Next_Node): Change index type to Int so that it properly
12848 covers the range First_Node_Id - 1 up.

12851 Ed Schonberg <schonberg@adacore.com>
12852 Bob Duff <duff@adacore.com>
12853 Hristian Kirtchev <kirtchev@adacore.com>
12855 * exp_aggr.ads, exp_aggr.adb:
12856 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12857 in extension aggregates.
12858 (Flatten): Other conditions being met, an aggregate is static if the
12859 low bound given by component associations is different from the low
12860 bound of the base index type.
12861 (Packed_Array_Aggregate_Handled): If the component type is itself a
12862 packed array or record, the front-end must expand into assignments.
12863 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12864 Init_Pr, instead of Ancestor_Is_Expression.
12865 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12866 coextension chain root, either generate a list controller or use the
12867 already existing one.
12868 (Static_Array_Aggregate): New procedure to construct a positional
12869 aggregate that can be handled by the backend, when all bounds and
12870 components are compile-time known constants.
12871 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12872 types covering interface types into assignments.
12873 (Replace_Type): move to Build_Record_Aggr_Code.
12874 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12875 interface type, convert to the definite type of the aggregate itself,
12876 so that needed components are visible.
12877 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12878 components and the context is an extended return statement do not
12879 create a transient block for it, to prevent premature finalization
12880 before the return is executed.
12881 (Gen_Assign): Do not generate a call to deep adjust routine if the
12882 component type is itself an array of controlled (sub)-components
12883 initialized with an inner aggregate.
12884 (Component_Check): New name for Static_Check. This name is now more
12885 appropriate, and documentation is added which was missing.
12886 (Component_Check): Add test for bit aligned component value
12887 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12888 Tagged_Comps, name is more appropriate given added function below.
12889 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
12891 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
12892 Javier Miranda <miranda@adacore.com>
12893 Robert Dewar <dewar@adacore.com>
12895 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12896 Terminated: Add unchecked type conversion from System.Address to
12897 System.Tasking.Task_Id when calling the predefined primitive
12899 Disable new Ada 05 accessibility check for JVM.NET targets, which
12900 cannot be implemented in a practical way.
12901 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12902 the sources always references the tag of the actual object. Therefore,
12903 if 'Tag is applied in the sources to class-wide interface objects we
12904 generate code that displaces "this" to reference the base of the object.
12905 (Expand_N_Attribute_Reference, case Size): Return specified size if
12906 known to front end.
12907 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12908 has code that displaces the pointer of the object to manage interface
12909 types. However this code must not be executed when the prefix is a
12910 subprogram. This bug caused the wrong expansion of the internally
12911 generated assignment that fills the dispatch table when the primitive
12912 is a function returning a class-wide interface type.
12913 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12914 Set_Attribute_Name for Name_Unaligned_Valid.
12916 2007-06-06 Ed Schonberg <schonberg@adacore.com>
12917 Gary Dismukes <dismukes@adacore.com>
12919 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12920 If the initialization is the equivalent aggregate of the initialization
12921 procedure of the type, do not remove it.
12922 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12923 initialized to null from having their expression reset to empty and
12924 note this exception in the comment.

12940 (Requires_Simple_Name_Prefix): Body of new function.
12941 (Resolve_Attribute, case Access): Improve error message for case of
12942 mismatched conventions.
12943 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
12945 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12946 constrained subtype for a nominal unconstrained type, use its base type
12947 to check for conformance with the context.
12948 (Resolve_Attribute): Remove test of the access type being associated
12949 with a return statement from condition for performing accessibility
12950 checks on access attributes, since this case is now captured by
12951 Is_Local_Anonymous_Access.
12952 (Analyze_Access_Attribute): Set Address_Taken on entity
12953 (Analyze_Attribute, case Address): Set Address_Taken on entity
12954 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
12955 validating an access attribute whose prefix is a current instance.
12956 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
12957 applied to dispatching operations, if freezing is required then we set
12958 the attribute Has_Delayed_Freeze in the prefix's entity.
12959 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
12960 current scope if access of local subprogram taken
12961 (Analyze_Access_Attribute): Check legality of self-reference even if the
12962 expression comes from source, as when a single component association in
12963 an aggregate has a box association.
12964 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
12965 the prefix if it is a protected operation and the attribute is
12966 Unrestricted_Access.
12967 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
12968 reference to the base type of the context, to force a constraint check
12969 when the context is an access subtype with an explicit constraint.
12970 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
12971 node is rewritten as an interface conversion. leave unanalyzed after
12972 resolution, to ensure that type checking against the context will take

12976 Javier Miranda <miranda@adacore.com>
12977 Robert Dewar <dewar@adacore.com>
12979 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
12980 wrapper when the full view of the controlling type of an inherited
12981 function that dispatches on result implements interfaces.
12982 (Expand_N_Object_Declaration): In cases where the type of the
12983 declaration is anonymous access, create finalization list for it.
12984 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
12985 if the object has no explicit initialization, to match description of
12986 functionality of pragam Persistent_BSS.
12987 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
12988 new function to build static aggregates, to replace initialization call
12989 when static initialization is desired.
12990 (Freeze_Type): Generate a list controller for an access type whenever
12991 its designated type has controlled anonymous access discriminants.
12992 (Build_Equivalent_Aggregate): New procedure to compute a static
12993 aggregate to be used as default initialization for composite types,
12994 instead of a generating a call to the initialization procedure for the
12996 (Build_Initialization_Call): When available, replace a call to the
12997 initialization procedure with a copy of the equivalent static aggregate
12999 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13000 declarations for objects of a class-wide interface type, rather than
13001 just identifiers, to prevent visibility problems.
13002 (Expand_N_Object_Declaration): When expanding the declaration for an
13003 object of a class-wide interface type, preserve the homonym chain of
13004 the original entity before exchanging it with that of the generated
13005 renaming declaration.
13006 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13007 active, because there is no way to handle the exception.
13008 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13009 to do a minimum decoration of the Access_Disp_Table list.
13010 (Expand_Record_Controller): Avoid the addition of the controller between
13011 the component containing the tag of a secondary dispatch table and its
13012 adjacent component that stores the offset to the base of the object.
13013 This latter component is only generated when the parent type has
13014 discriminants ---documented in Add_Interface_Tag_Components).
13015 (Apply_Array_Size_Check): Removed, no longer needed.
13016 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13017 components, create a Master_Entity for it only if it contains tasks.
13018 (Build_Init_Procedure): Suppress the tag assignment compiling under
13020 (Freeze_Record_Type): Remove code associated with creation of dispatch
13022 (Init_Secondary_Tags): Update type of actuals when generating calls to
13023 Ada.Tags.Set_Offset_To_Top
13024 (Stream_Operation_OK): Disable use of streams compiling under no
13026 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13027 if Has_Init_Expression set.
13028 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13029 Register_Primitive, which provides the same functionality.
13030 (Requires_Init_Proc): Return false in case of interface types.
13031 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13033 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13034 is always associated with a predefined primitive because the internal
13035 entities associated with interface types are not predefined primitives.
13036 Therefore, the call to Is_Internal is replaced by a call to the
13037 function Is_Predefined_Dispatching_Operation.
13038 (Make_Eq_If): When generating the list of comparisons for the
13039 components of a given variant, omit the controller component that is
13040 present if the variant has controlled components.
13042 2007-06-06 Javier Miranda <miranda@adacore.com>
13043 Hristian Kirtchev <kirtchev@adacore.com>
13044 Bob Duff <duff@adacore.com>
13046 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13047 handle the creation of finalization lists and calls for nested
13048 coextensions when the root of the chains is part of a return statement.
13049 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13051 (Expand_Record_Equality): Skip components that are interface types.
13052 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13053 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13054 with Rewrite_Coextension. Change the condition for detecting coextension
13056 (Is_Local_Access_Discriminant): Removed.
13057 (Rewrite_Coextension): New routine which rewrites a static coextension
13058 as a temporary and uses its unrestricted access in the construction of
13060 (Complete_Coextension_Finalization): New routine. Generate finalization
13061 attachment calls to all delayed coextensions.
13062 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13063 the allocator is not a coextension itself and has delayed coextensions.
13064 If the current allocator is controlled, but also a coextension, delay
13065 the generation of the finalization attachment call.
13066 Rename local variable "Node" to "Nod" in order to avoid confusion with
13068 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13069 limited types that are not inherently limited. Such an allocator is
13070 illegal, but is generated by the expander for a return statement, to
13071 copy the result onto the secondary stack. This is the only case where a
13072 limited object can be copied. Generate code to displace the pointer
13073 to the object if the qualified expression is a class-wide interface
13074 object. Such displacement was missing and hence the copy of the object
13076 (Apply_Accessibility_Check): Handle allocated objects initialized in
13078 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13079 and Expand_Allocator_Expression. Allocating class-wide interface objects
13080 this routine displaces the pointer to the allocated object to reference
13081 the component referencing the corresponding secondary dispatch table.
13082 Expand_Allocator_Expression): Add missing support to allocate class-wide
13083 interface objects initialized with a qualified expression.
13084 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13085 function result type, and use the finalization list associated with the
13086 function scope in that case (such an anonymous type should not be
13087 treated like an access parameter's type).
13089 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13090 Gary Dismukes <dismukes@adacore.com>
13091 Javier Miranda <miranda@adacore.com>
13093 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13094 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13095 required exception handler.
13096 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13097 properly the case of a function whose return type is a limited
13098 class-wide interface type. Modify the code of the accessibility
13099 check to handle class-wide interface objects. In this case we need to
13100 displace "this" to reference the primary dispatch table to get access
13101 to the TSD of the object (to evaluate its accessibility level).
13102 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13103 rather than a controlling result as one of the conditions for
13104 generating tests of the implicit BIP_Alloc_Form formal. The
13105 initialization assignment is also handled according to whether the
13106 result is tagged instead of controlling.
13107 In the case where the init assignment is inserted in the "then" part of
13108 the allocation conditional, rewrite the target to be a dereference of
13109 the implicit BIP_Object_Access formal.
13110 If the returned value is unconstrained and created on the secondary
13111 stack, mark the enclosing block and function so that the secondary
13112 stack is not reclaimed on return.
13113 Treat returns from functions with controlling results similarly to
13114 returns from functions with unconstrained result subtypes.
13115 If the object returned is unconstrained, and an allocator must be
13116 created for it, analyze the allocator once the block for the extended
13117 return is installed, to ensure that finalizable components
13118 of the expression use the proper finalization list. Guard the call to
13119 Move_Final_List with a check that there is something to finalize.
13120 (Make_Tag_Ctrl_Assignment): Use "old" handling
13121 of controlled type assignment for virtual machines, since new code uses
13122 unsupported features (such as direct access to bytes in memory).
13124 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13125 Ed Schonberg <schonberg@adacore.com>
13127 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13128 accessibility actual, check for the case of an aliased object that has
13129 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13130 we fall into processing for the attribute rather than the name of the
13132 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13133 formal has its address taken in the body, create a temporary to capture
13134 value. If the return type is a limited interface, do not treat the
13135 return value as Controlled.
13136 (Is_In_Place_Function): If the return type is a limited interface,
13137 treat as returning in place. The actual returned object may not always
13138 be limited, but the caller has to assume that it is returned in place.
13139 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13140 context of an allocator, use the correct finalization chain (that is,
13141 the chain belonging to the access type, rather than the chain belonging
13142 to the current scope).
13143 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13144 result type rather than a controlling result as a precondition for
13145 adding an allocation form actual to a build-in-place call.
13146 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13147 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13148 primitive in the dispatch tables. This work is now done by Make_DT when
13149 the type is frozen.
13150 (Register_Predefined_DT_Entry): Removed.
13151 (Add_Return): If end label is not present, use sloc of last statement
13152 for generated return statement in procedure, for better gdb behavior
13154 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13155 object address nodes to ensure proper processing by routines like
13157 (Expand_Call): Fix generation of validity check for parameter
13158 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13159 the allocation form parameter if the result subtype is constrained,
13160 except when the function has a controlling result.
13161 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13162 rather than Is_Controlled and Has_Controlled_Component, since we want to
13163 include class-wide result types in this treatment. Also test for a
13164 controlling result, since that also requires passing a finalization
13166 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13167 even when the result subtype is constrained, to handle calls involving
13168 controlling results.
13169 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13170 is now called even when the result subtype is constrained, to handle
13171 calls involving controlling results.
13172 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13173 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13174 now performs the test).
13175 (Make_Build_In_Place_Call_In_Object_Declaration):
13176 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13177 constrained, to handle calls involving controlling results.
13178 (Add_Return): Accomodate rewritten pattern from local raise to goto
13179 transformation, so that we still recognize an transfer statement
13180 and do the right thing here in that case.
13181 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13182 and end of subprogram code.
13183 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13184 support for primitives that are functions (without formals) with a
13185 controlling result.
13186 (Inherited_From_Formal): If the actual subtype has not generic parent
13187 type, it is not an actual for a formal derived type, and there is no
13188 operation to inherit from the formal.
13190 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13191 Thomas Quinot <quinot@adacore.com>
13193 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13194 inserted cleanup code appropriately for GDB use.
13195 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13196 exception handler for Deep_Adjust or Deep_Finalize.
13197 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13198 Raise_From_Controlled_Operation is available, use a call to that
13199 subprogram instead of a plain "raise Program_Error" node to raise
13200 Program_Error if an exception is propagated from an Adjust or Finalize
13202 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13203 appears in the optional statement list of a triggering alternative, the
13204 scope actions can be inserted directly there, and not in the list that
13205 includes the asynchronous select itself.

13209 Hristian Kirtchev <kirtchev@adacore.com>
13211 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13212 generated exception handler appropriately when debugging generated code.
13213 Deal properly with No_Exception_Propagation restriction mode.
13214 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13215 System.Address to System.Tasking.Task_Id when processing the result of
13216 the predefined primitive _disp_get_task_id.
13217 (Expand_N_Asynchronous_Select): Clarify comment.
13218 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13219 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13220 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13221 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13222 privals and for generated call to Complete_Entry_Body, for better gdb
13224 (Copy_Result_Type): Utility to construct a parameter and result profile
13225 for protected functions whose return type is an anonymous access to
13227 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13229 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13230 point when the local-raise-to-goto transformation has taken place.
13232 2007-06-06 Javier Miranda <miranda@adacore.com>
13233 Nicolas Setton <setton@adacore.com>
13235 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13236 functionality when the backend is generating code.
13237 Otherwise any serious error
13238 reported by the backend calling the frontend routine Error_Msg
13239 changes the Compilation_Mode to Check_Semantics, disables the
13240 functionality of this routine and causes the generation of
13241 spureous additional errors.
13243 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13244 debugging information now generated by the compiler for fat-pointer
13246 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13248 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13250 2007-06-06 Thomas Quinot <quinot@adacore.com>
13252 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13253 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13254 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13255 For a remote call to a function with a classwide return type, apply an
13256 E.4(18) check to the returned value.
13257 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13258 stream attributes of the designated type of an RACW, as they are not
13259 dispatching primitive operations.
13261 2007-06-06 Geert Bosch <bosch@adacore.com>
13263 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13265 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13267 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13268 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13270 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13272 2007-06-06 Javier Miranda <miranda@adacore.com>
13274 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13275 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13277 2007-06-06 Javier Miranda <miranda@adacore.com>
13279 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13280 deallocation of class-wide interface objects.
13281 (Expand_Dispatching_Constructor_Call): Take into account that if the
13282 result of the dispatching constructor is an interface type, the
13283 function returns a class-wide interface type; otherwise the returned
13284 object would be actual. The frontend previously accepted returning
13285 interface types because Expand_Interface_Actuals silently performed
13286 the management of the returned type "as if" it were a class-wide
13288 (Expand_Dispatching_Constructor_Call): Replace call to
13289 Make_DT_Access_Action by direct call to Make_Function_Call.
13291 2007-06-06 Robert Dewar <dewar@adacore.com>
13292 Ed Schonberg <schonberg@adacore.com>
13294 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13295 compute masking constant, since we now set Esize properly to the
13297 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13298 to match the alignment.
13299 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13300 packed arrays of 8 bits or less.
13302 * freeze.adb (Freeze_Entity): When freezing the formals of a
13303 subprogram, freeze the designated type of a parameter of an access type
13304 only if it is an access parameter.
13305 Increase size of C convention enumeration object
13306 (Freeze_Entity, array type case): Make sure Esize value is properly
13307 adjusted for the alignment if it is known.
13308 (Freeze_Entity, array type case): When checking bit packed arrays for
13309 the size being incorrect, check RM_Size, not Esize.
13310 (Freeze_Record_Type): Check for bad discriminated record convention
13311 (In_Exp_Body): Return true if the body is generated for a subprogram
13312 renaming, either an attribute renaming or a renaming as body.
13313 (Check_Itype): If the designated type of an anonymous access component
13314 is a non-protected subprogram type, indicate that it is frozen, to
13315 prevent out-of-scope freeze node at some subsequent call.
13316 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13317 only if the subprogram is neither imported nor exported, as well as the
13318 NCA descriptor class if the subprogram is exported.

13323 Gary Dismukes <dismukes@adacore.com>
13325 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13326 default initialization on an imported object, when there is no
13327 initialization call generated for it.
13328 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13331 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13332 Static_Elaboration_Desired.
13333 Remove pragma Thread_Body.
13334 Implement a new pragma No_Body
13335 Removes the Explicit_Overriding pragma
13336 Remove Optional_Overriding pragma
13337 (Prag): Deal with Universal_Aliasing.
13338 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13339 Pragma_CIL_Constructor): New names.
13341 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13342 uses the equivalent aggregate of a type must be treated as an implicit
13344 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13345 has none of the other categories.
13346 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13347 to apply Import to an object renaming declaration.
13349 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13350 from a C++ class should be declared as limited and that it will be
13351 considererd limited.
13352 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13353 should be declared as limited and that it will be considererd limited.
13354 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13355 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
13356 (Analyze_Pragma): Deal with Universal_Aliasing.
13357 (Sig_Flags): Likewise.
13358 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
13359 (Overflow_Checks_Unsuppressed): New flag.
13360 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
13361 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
13362 case of JVM or .NET targets, and compiling user code.
13363 Add debugging convenience routine rv
13365 2007-06-06 Robert Dewar <dewar@adacore.com>
13367 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
13368 are interface type.
13369 (Build_Elementary_Input_Call): For floating-point use right type in the
13370 absence of strange size or stream size clauses.
13371 (Build_Elementary_Write_Call): Same fix
13372 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
13373 set to value that does not match base type size.
13375 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13377 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13378 object of a limited type can be initialized with a call to a function
13379 that returns in place. If the limited type has unknown discriminants,
13380 and the underlying type is a constrained composite type, build an actual
13381 subtype from the function call, as is done for private types.
13382 (Side_Effect_Free): An expression that is the renaming of an object or
13383 whose prefix is the renaming of a object, is not side-effect free
13384 because it may be assigned through the renaming and its value must be
13385 captured in a temporary.
13386 (Has_Controlled_Coextensions): New routine.
13387 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13388 as is done for other limited types.
13389 (Non_Limited_Designated_Type): new predicate.
13390 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
13392 Remove all handling of with_type clauses.
13394 * par-ch10.adb: Remove all handling of with_type clauses.
13396 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
13397 checksum if the main source could not be parsed.
13398 (Loat_Unit): When processing a child unit, determine properly whether
13399 the parent unit is a renaming when the parent is itself a child unit.

15208 a return statement's finalization list to the caller's list, used for
15209 build-in-place functions with result type with controlled parts.
15210 Remove no longer used entities.
15212 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
15213 longer needed, because the full type is now limited, and therefore a
15214 pass-by-reference type.
15215 (Foreign_Task_Level): New constant.
15217 * s-tassta.ads, s-tassta.adb (Move_Activation_Chain): New procedure to
15218 move tasks from the activation chain belonging to a return statement to
15219 the one passed in by the caller, and update the master to the one
15220 passed in by the caller.
15221 (Vulnerable_Complete_Master, Check_Unactivated_Tasks): Check the master
15222 of unactivated tasks, so we don't kill the ones that are being returned

15246 to handle properly the anonymous access case.
15248 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
15249 for all access attributes, because overload resolution should work the
15250 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
15251 causes the error message for the ambiguous "X'Access = Y'Access" and
15252 "X'Unrestricted_Access = Y'Access" and so forth to match.
15253 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
15254 now that anonymous access to protected operations have their own kind.
15255 (Resolve_Attribute): In case of dispatching call check the violation of
15256 restriction No_Dispatching_Calls.
15257 (Check_Array_Type): Check new -gnatyA array index style option

15260 attempt to derive from a synchronized tagged type.
15261 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
15262 type, inherit the class-wide type already created, because it may
15263 already have been used in a self-referential anonymous access component.
15264 (Mentions_T): Recognize self-referential anonymous access components
15265 that use (a subtype of) the class-wide type of the enclosing type.
15266 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15267 Derived_Type for Prev formal on call to
15268 Check_Anonymous_Access_Components rather than Empty.
15269 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15270 a record extension in deciding whether to create a class-wide type,
15271 rather than just checking Tagged_Present.
15272 (Replace_Anonymous_Access_To_Protected_Subprogram): Procedure applies
15273 to stand-alone object declarations as well as component declarations.
15274 (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to
15275 prevent accidental overwriting when enclosing package appears in
15276 a limited_with_clause.
15277 (Array_Type_Declaration): If the component type is an anonymous access,
15278 the associated_node for the itype is the type declaration itself.

15280 types with abstract interfaces.
15281 (Check_Abstract_Interfaces): New subprogram that verifies the ARM
15282 rules 3.9.4 (15/2), 9.1 (9.d/2) and 9.4 (11.d/2).
15283 (Build_Derived_Record_Type): Add call to Analyze_Interface_Declaration
15284 to complete the decoration of synchronized interface types. Add also
15285 a call to Check_Abstract_Interfaces to verify the ARM rules.
15286 (Derive_Interface_Subprograms): Modified to support concurrent types
15287 with abstract interfaces.
15288 (Analyze_Subtype_Indication): Resolve the range with the given subtype
15289 mark, rather than delaying the full resolution depending on context.

15314 (Collect_Arguments): Do not check for sources outside of projects.
15315 Do not collect arguments if project is externally built.
15316 (Compile_Sources): Do nothing, not even check if the source is up to
15317 date, if its project is externally built.
15318 (Compile): When compiling a predefined source, add -gnatpg
15319 as the second switch, after -c.
15320 (Compile_Sources): Allow compilation of Annex J renames without -a
15321 (Is_In_Object_Directory): Check if the ALI file is in the object
15322 even if there is no project extension.
15323 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
15324 gnatbind if the ALI file effectively exists.
15325 (Initialize): Add the directory where gnatmake is invoked in front of
15326 the path if it is invoked from a bin directory, even without directory
15327 information, so that the correct GNAT tools will be used when spawned
15328 without directory information.

15347 renamings Calendar, Machine_Code, Unchecked_Conversion and
15348 Unchecked_Deallocation only when Renamings_Included is True.
15350 * par.adb: Allow library units Calendar, Machine_Code,
15351 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15352 when -gnatg is not specified.
15353 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15354 there is no need to generate always a record_definition_node in case
15355 of synchronized interface types.
15356 (SIS_Entry_Active): Initialize global variable to False
15357 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

15378 If the array component is a discriminated record, the array aggregate
15379 is non-static even if the component is given by an aggregate with
15381 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
15382 (Convert_Aggr_In_Allocator): If the allocator is for an access
15383 discriminant and the type is controlled. do not place on a finalization
15384 list at this point. The proper list will be determined from the
15386 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
15387 initialize record controller if needed, before the components, to ensure
15388 that they are properly finalized.
15389 (Build_Record_Aggr_Code): For the case of an array component that has a
15390 corresponding array aggregate in the record aggregate, perform sliding

15401 accessibility on class-wide allocators if the allocator occurs at the
15402 same scope level as the allocator's type. The check is guaranteed to
15403 succeed in that case, even when the expression originates from a
15404 parameter of the containing subprogram.
15405 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15406 under No_Dispatching_Calls restriction. During the semantic analysis
15407 we already notified such violation.
15408 (Tagged_Membership): Constant folding. There is no need to check
15409 the tag at run-time if the type of the right operand is non
15410 class-wide abstract.
15411 Replace call to Is_Ancestor by call to Is_Parent
15412 to support concurrent types with interface types.
15413 (Expand_N_Allocator): Add an assertion associated with the generation

15424 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
15425 initialize most the TSD components by means of an aggregate.
15426 Modify the declaration of the object containing the TSD
15427 because we now expand code that has a higher level of abstraction.
15428 The TSD has a discriminant containing the Inheritance Depth Level,
15429 value that is used in the membership test but also to fix the size
15430 of the table of ancestors.
15431 (Expand_Interface_Conversion): Insert function body at the closest place
15432 to the conversion expression, to prevent access-before-elaboration
15433 errors in the backend.
15434 Code improved to reduce the size of the dispatch table if
15435 compiling under restriction No_Dispatching_Calls plus code cleanup.
15436 Code reorganization plus removal of calls to Set_Num_Prim_Ops
15437 (Make_Secondary_DT): Remove call to Set_Num_Prim_Ops.

15458 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
15459 (Expand_Dispatching_Call): Replace generation of call to the run-time
15460 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15461 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15463 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15464 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
15465 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
15466 Build_Set_Prim_Op_Address.
15467 (Get_Remotely_Callable): Subprogram removed.
15468 (Init_Predefined_Interface_Primitives): Replace generation of call to
15469 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
15472 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15473 First (Parameter_Associations ()) with the call to First_Actual that
15474 returns an actual parameter expression for both named and positional
15477 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15478 check violation of restriction No_Dispatching_Calls.
15479 (Check_Controlling_Type): A formal of a tagged incomplete type is a
15480 controlling argument.
15482 * exp_util.ads, exp_util.adb (Type_May_Have_Bit_Aligned_Components): Use
15483 First/Next_Component_Or_Discriminant
15484 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
15485 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15486 specify Any_Limited_Interface, and this functionality is already
15487 provided by the function Has_Abstract_Interfaces.
15488 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15489 support concurrent types implementing interfaces.
15490 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15491 specify kind Any_Limited_Interface, and this functionality is already
15492 provided by the function Has_Abstract_Interfaces.
15493 (Remove_Side_Effects): replace Controlled_Type by
15494 CW_Or_Controlled_Type whenever the issue is related to
15495 using or not the secondary stack.
15497 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
15498 P_Interface_Type_Definition to fulfill the new interface (the formal
15499 Is_Synchronized is no longer required).
15501 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o

15511 anonymous, use finalization list of enclosing dynamic scope.
15512 (Expand_N_Package_Declaration): For a library package declaration
15513 without a corresponding body, generate RACW subprogram bodies in the
15514 spec (just as we do for the task activation call).
15515 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15516 Is_Abstract_Type. Make sure these are called only when appropriate.
15517 Remove all code for DSP option

15524 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15525 parameter. If it is set to true, return a result capped according to
15526 the global upper bound for the index of an entry family.

15528 (Build_Find_Body_Index): Adjust for above change.
15529 (Entry_Index_Expression): Likewise.

15534 Family_Size with 'Cap' set to true.
15535 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15536 a protected version of an operation declared in the private part of
15537 a protected object, because they may be invoked through a callback.
15538 (Set_Privals): If the type of a private component is an anonymous access
15539 type, do not create a new itype for each protected body.
15540 If the body of a protected operation creates
15541 controlled types (including allocators for class-widetypes), the
15542 body of the corresponding protected subprogram must include a
15544 (Build_Activation_Chain_Entity): Build the chain entity for extended
15546 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15547 to determine whether operation overrides an inherited primitive.
15548 (Build_Wrapper_Spec): Add code to examine the parents while looking
15549 for a possible overriding candidate.
15550 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15551 hold an actual parameter value since its initialization is separated
15552 from the the declaration. Prevents errors on null-excluding access

15556 Pablo Oliveira <oliveira@adacore.com>
15558 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15559 Do an Unchecked_Conversion to handle the passage from the Underlying
15560 Type to the Base Type when calling Build_To_Any_Call and
15561 Build_From_Any_Call.
15562 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15563 E_Constant, depending upon Variable formal.
15564 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15565 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15566 parameter that requires an extra constrained parameter, declare
15567 temporary for actual as a variable, not a constant.
15568 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15569 the unit being compiled is the one that contains the stub type.
15570 Change primitive operation name for the RACW associated with a RAS
15571 from Call to _Call so it cannot clash with any legal identifier.
15572 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15574 (Append_RACW_Bodies): New subprogram.
15575 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15576 Add_Receiving_Stubs_To_Declarations functions.
15577 When expanding a package body, this list correspond to the
15578 statements in the HSS at the end of the pacakge.
15579 When expanding a package spec, this list correspond to the
15581 (Add_Receiving_Stubs_To_Declarations): Append the function
15582 registering the receiving stubs at the end of the 'Stmts' list.
15583 (RCI_Package_Locator): Pass the new Version generic formal when
15584 instantiating a RCI_Locator package.
15585 (Build_From_Any_Function): To compute the High bound for an
15586 unconstrained array actual, we add the Low bound with the length.
15587 Thus we must convert the low bound and the length to an appropriate
15588 type before doing the sum.
15589 (Build_Subprogram_Receiving_Stubs, PolyORB):
15590 * Retrieve the extra formals parameters at the
15591 end of the parameter stream.
15592 * Use Move_Any_Value to write back out parameters
15593 after executing the request as it is more efficient
15594 than Copy_Any_Value.
15595 * Build the any containing Extra Formals with the
15596 appropriate typecode.
15597 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15598 empty Component_List.
15599 (Build_Actual_Object_Declaration): New subprogram. Build and insert into

15606 Extra Constrained Parameters.
15607 (Build_General_Calling_Stubs): Set the parameter type to boolean for

15611 function with the first not implicit parent type.
15612 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15613 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15614 typecode from the Etype. Therefore we retrieve the correct typecode
15615 with a call to Get_Any_Type.
15616 (Copy_Specification): Do controlling formal type substitution based on
15617 Is_Controlling_Formal flag, instead of caller-provided object type.
15618 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15619 a RACW primitive operation, we might get a subprogram declaration for an
15620 ancestor of the RACW designated type (not for the designated type
15621 itself), in the case where this operation is inherited. In this case we
15622 have no easy means of determining the original tagged type for which
15623 the primitive was declared, so instead we now rely on
15624 Copy_Specification to use the Is_Controlling_Formal flag to determine
15625 which formals require type substitution.

16110 non-limited view is available, use the non-limited one.
16111 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16112 therefore illegal), suggest a qualified expression rather than a type
16113 conversion, because a type conversion would be illegal in this context.
16114 (Anayze_Allocator): Trace recursively all nested allocators so that all
16115 coextensions are on the corresponding list for the root. Do no mark
16116 coextensions if the root allocator is within a declaration for a stack-
16117 allocated object, because the access discriminants will be allocated on
16119 (Analyze_Call): Remove restriction on calls to limited functions for the
16120 cases of generic actuals for formal objects, defaults for formal objects
16121 and defaults for record components.
16122 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16123 element list. Their expansion is delayed until the enclosing allocator
16124 is processed and its finalization list constructed.
16125 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16126 for an operation with the given name among the primitive operations of
16127 the corresponding record type.
16128 (Analyze_Selected_Component): If the prefix is a task type that
16129 implements an interface, and there is no entry with the given name,
16130 check whether there is another primitive operation (e.g. a function)
16132 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16133 properly the indexing of a function call written in prefix form, where
16134 the function returns an array type, and all parameters of the function
16135 except the first have defaults.
16136 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16137 the original operands, rather than relocating them, for efficiency and
16138 to work properly when an operand is overloaded.
16139 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16140 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16141 (Analyze_Selected_Component): If the prefix is a private extension, only
16142 scan the visible components, not those of the full view.
16143 (Try_Primitive_Operation): If the operation is a procedure, collect all
16144 possible interpretations, as for a function, because in the presence of
16145 classwide parameters several primitive operations of the type can match
16146 the given arguments.

16159 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16160 out of Analyze_Package_Declaration, because processing must be applied
16161 to package bodies as well, for deferred constants completed by pragmas.
16162 (Analyze_Package_Declaration): When the package declaration being
16163 analyzed does not require an explicit body, call Check_Completion.
16164 (May_Need_Implicit_Body): An implicit body is required when a package
16165 spec contains the declaration of a remote access-to-classwide type.
16166 (Analyze_Package_Body): If the package contains RACWs, append the
16167 pending subprogram bodies generated by exp_dist at the end of the body.
16168 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16169 Is_Abstract_Subprogram and Is_Abstract_Type.
16170 (Preserve_Full_Attributes): The full entity list is not an attribute
16171 that must be preserved from full to partial view.
16173 * sem_dist.adb (Add_RAS_Dereference_TSS):
16174 Change primitive name to _Call so it cannot clash with any legal
16175 identifier, and be special-cased in Check_Completion.
16176 Mark the full view of the designated type for the RACW associated with
16177 a RAS as Comes_From_Source to get proper view switching when installing
16178 private declarations.
16179 Provite a placeholder nested package body along with the nested spec
16180 to have a place for Append_RACW_Bodies to generate the calling stubs
16181 and stream attributes.
16183 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16184 Robert Dewar <dewar@adacore.com>

16192 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16193 renaming as body when renamed entity is abstract.

16210 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16211 dereference of a local object R created as a reference to another
16212 object O, use the access level of O.
16213 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16214 rather than local Same_Formal_Type, to check whether protected operation
16215 overrides an inherited one.
16216 (Same_Formal_Type): New predicate, used when matching signatures of
16217 overriding synchronized operations, to handle the case when a formal
16218 has a type that is a generic actual.
16219 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16220 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16221 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16222 syntactic ambiguities involving indexing of function calls that return
16224 (Abstract_Interface_List): New subprogram that returns the list of
16225 abstract interfaces associated with a concurrent type or a
16226 concurrent record type.
16227 (Interface_Present_In_Parent): New subprogram used to check if a
16228 given type or some of its parents implement a given interface.
16229 (Collect_Abstract_Interfaces): Add support for concurrent types
16230 with interface types.
16231 (Has_Abstract_Interfaces): Add support for concurrent types with
16233 (Is_Parent): New subprogram that determines whether E1 is a parent
16234 of E2. For a concurrent type its parent is the first element of its
16235 list of interface types; for other types this function provides the
16236 same result than Is_Ancestor.
16237 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16238 (Collect_Synchronized_Interfaces): Removed because the subprogram
16239 Collect_Abstract_Interfaces provides this functionality.
16240 (Collect_Abstract_Interfaces): Minor update to give support to
16241 concurrent types and thus avoid undesired code duplication.
16242 (Get_Subprogram_Entity): Handle entry calls.
16243 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16245 (Enter_Name): Do not give -gnatwh hiding warning for record component

16261 can be an E_Return_Statement.
16262 (Is_Coextension): New flag for allocators.

16281 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16282 expression with a COMPOUND_EXPR including the call instead of emitting
16283 the call directly here.
16284 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16285 high bound is constant and the slice is empty. Tidy.
16286 (tree_transform, case N_Op_Not): Handle properly the case where the
16287 operation applies to a private type whose full view is a modular type.
16288 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16289 Address_Clause, use the associated Expression as the GNAT tree
16290 representing the choice value to ensure the corresponding GCC tree is
16291 of the proper kind.
16292 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16293 instead of just the operands, as the base GCC stabilize_reference does.
16294 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16295 requested; otherwise fail.
16296 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16301 implementation of UI_Div.
16302 (UI_Div): Reimplement as a call to UI_Div_Rem.
16303 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16304 remainder, avoiding the cost of a multiplication and a subtraction.

16308 functions for uint.
16309 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram

16552 (Resolve_Arithmetic_Op): Do not give an error on calls to the
16553 universal_fixed "*" and "/" operators when they are used in a context
16554 that expects any real type. Also set the type of the node to

16556 (mainly static expression evaluation).
16557 Reword some continuation messages
16558 Add some \\ sequences to continuation messages
16559 (Resolve_Call): Refine infinite recursion case. The test has been

17095 (Set_All_DT_Position): Hidden entities associated with abstract
17096 interface primitives are not taken into account in the check for

17109 (Make_DT): If the ancestor of the type is a CPP_Class and we are
17110 compiling under full ABI compatibility mode we avoid the generation of
17111 calls to run-time services that fill the dispatch tables because under
17112 this mode we currently inherit the dispatch tables in the IP subprogram.
17113 (Write_DT): Emit an "is null" indication for a null procedure primitive.
17114 (Expand_Interface_Conversion): Use an address as the type of the formal

17167 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17168 assignments where the target subtype is unconstrained and the target
17169 object is a parameter or dereference (other aliased cases are known

17287 (Replace_Self_Reference): New subsidiary of
17288 Make_OK_Assignment_Statement, to replace an access attribute that is a
17289 self-reference into an access to the appropriate component of the

17291 nested at any level.
17292 (Is_Self_Referential_Init): Remove, not needed.

17304 that has been derived from several abstract interfaces we must also

17334 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17335 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17336 an aliased prefix must be known to be constrained in order to use True
17337 for the attribute value, and now it's possible for some aliased views
17338 to be unconstrained.

17357 required to report the correct error message.
17358 (Expand_N_Subtype_Indication): Do validity checks on range
17359 (Clean_Task_Names): If an initialization procedure includes a call to

17369 Object_Declaration to the call.
17370 (Freeze_Type): When the designated type of an RACW was not frozen at the
17371 point where the RACW was declared, validate the primitive operations
17372 with respect to E.2.2(14) when it finally is frozen.
17373 (Build_Initialization_Call,Expand_Record_Controller): Rename
17374 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17375 return-by-reference has no meaning in Ada 2005.
17376 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17377 to register tag of the immediate ancestor interfaces in the
17378 run-time structure.

17380 initialization of extension aggregates with abstract interfaces.
17381 (Build_Master_Renaming): Make public, for use by function declarations
17382 whose return type is an anonymous access type.
17383 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17384 Insert_List_Before_And_Analyze after the generation of the specs
17385 associated with null procedures.

17387 (Init_Secondary_Tags): Update documentation.
17388 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17389 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17390 then generate code to inherit the contents of the dispatch table
17391 directly from the ancestor.
17392 (Expand_Record_Controller): Insert controller component after tags of
17393 implemented interfaces.

17399 (Is_Null_Interface_Procedure): New function in
17400 Make_Null_Procedure_Specs.
17401 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17402 immediate ancestor of a tagged type is an abstract interface type we
17403 must generate the specification of the predefined primitives associated
17404 with controlled types (because the dispatch table of the ancestor is
17405 null and hence these entries cannot be inherited). This is required to
17406 elaborate well the dispatch table.

17420 the maximum for type T.
17421 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17422 when the allocator is initialized by a build-in-place call, since the
17423 allocator is already rewritten as a reference to the function result,
17424 and this prevents an unwanted duplication of the function call.
17425 Add with and use of Exp_Ch6.
17426 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17427 is a call to build-in-place function and apply
17428 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17429 untagged designated types).

17435 discriminants of anonymous access types (AI-402, AI-416)
17437 2006-10-31 Bob Duff <duff@adacore.com>
17438 Robert Dewar <dewar@adacore.com>
17439 Gary Dismukes <dismukes@adacore.com>
17440 Ed Schonberg <schonberg@adacore.com>
17442 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17444 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17445 (Expand_N_Assignment_Statement): Call
17446 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17447 build-in-place function call. Currently, this can happen only for
17448 assignments that come from aggregates.
17449 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17450 in order to alleviate the upward compatibility introduced by AI-318.
17451 (Expand_N_Extended_Return_Statement): Add support for handling the
17452 return object as a build-in-place result.
17453 (Expand_Non_Function_Return): Implement simple return statements nested
17454 within an extended return.
17455 (Enable_New_Return_Processing): Turn on the new processing of return
17457 (Expand_Non_Function_Return): For a return within an extended return,
17458 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17459 (Expand_N_Extended_Return_Statement): Implement AI-318
17460 (Expand_Simple_Function_Return): Ditto.
17461 (Expand_N_If_Statement): Handle new -gnatwt warning
17462 (Expand_N_Case_Statement): Handle new -gnatwt warning
17463 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17464 a protected object.
17465 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17466 validity checking of assignments to elementary record components.
17467 (Expand_N_Return_Statement): return Class Wide types on the secondary
17468 stack independantly of their controlled status since with HIE runtimes,
17469 class wide types are not potentially controlled anymore.
17471 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17474 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17475 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17476 it expects a block, procedure, or task. The return statement will get
17477 turned into a block, and Expand_Cleanup_Actions will happen then.
17479 2006-10-31 Robert Dewar <dewar@adacore.com>
17480 Ed Schonberg <schonberg@adacore.com>
17481 Bob Duff <duff@adacore.com>
17482 Gary Dismukes <dismukes@adacore.com>
17484 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17486 (Expand_Inlined_Call): Tagged types are by-reference types, and
17487 therefore should be replaced by a renaming declaration in the expanded
17488 body, as is done for limited types.
17489 (Expand_Call): If this is a call to a function with dispatching access
17490 result, propagate tag from context.
17491 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17493 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17494 build-in-place when the right-hand side of an assignment is a
17495 build-in-place function call.
17496 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17497 of the explicit dereference of the allocator to the result subtype of
17498 the build-in-place function. This is needed to satisfy type checking
17499 in cases where the caller's return object is created by an allocator for
17500 a class-wide access type and the type named in the allocator is a
17502 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17503 conversion of the reference to the declared object to the result subtype
17504 of the build-in-place function. This is needed to satisfy type checking
17505 in cases where the declared object has a class-wide type. Also, in the
17506 class-wide case, change the type of the object entity to the specific
17507 result subtype of the function, to avoid passing a class-wide object
17508 without explicit initialization to the back end.
17509 (Register_Interface_DT_Entry): Moved outside the body of
17510 Freeze_Subprogram because this routine is now public; it is called from
17511 Check_Dispatching_Overriding to handle late overriding of abstract
17512 interface primitives.
17513 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17514 adding an implicit access actual on a call to a build-in-place function.
17515 (Expand_Actuals): Test for an actual parameter that is a call to a
17516 build-in-place function and apply
17517 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17518 (Is_Build_In_Place_Function): New function to determine whether an
17519 entity is a function whose calls should be handled as build-in-place.
17520 (Is_Build_In_Place_Function_Call): New function to determine whether an
17521 expression is a function call that should handled as build-in-place.
17522 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17523 calls to build-in-place functions as the initialization of an allocator.
17524 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17525 handling calls to build-in-place functions in contexts that do not
17526 involve init of a separate object (for example, actuals of subprogram
17528 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17529 handling calls to build-in-place functions as the initialization of an
17530 object declaration.
17531 (Detect_Infinite_Recursion): Add explicit parameter Process to
17532 instantiation of Traverse_Body to avoid unreferenced warning.
17533 (Check_Overriding_Inherited_Interfaces): Removed.
17534 (Register_Interface_DT_Entry): Code cleanup.
17535 (Register_Predefined_DT_Entry): Code cleanup.
17536 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17537 inlined statements if within a transient scope.
17538 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17539 formal parameters with occurrences of actuals in inlined body, establish
17540 visibility on the proper view of the actual's subtype for the body's
17542 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17543 compatibility mode and we have an imported CPP subprogram because
17544 for now we assume that imported CPP primitives correspond with
17545 objects whose constructor is in the CPP side (and therefore we
17546 don't need to generate code to register them in the dispatch table).
17547 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17548 aligned selected component.
17549 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17550 the actual of an in-mode parameter is a type conversion.
17551 (Expand_Actuals): If the call does not come from source and the actual
17552 is potentially misaligned, let gigi handle it rather than rejecting the
17553 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17554 Class Wide types as returning by reference independantly of their
17555 controlled status since with HIE runtimes class wide types are not
17556 potentially controlled anymore.
17558 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17560 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17561 references that are private components of the protected object.
17562 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
17563 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17564 instantiation to deal with warnings.
17565 (Initialize_Protection): If expression for priority is non-static, use
17566 System_Priority as its expected type, in case the expression has not
17569 2006-10-31 Robert Dewar <dewar@adacore.com>
17571 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17572 initialization of Homonym_Len.
17573 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17574 names from fully qualified name. Fixes problem of duplicate
17575 external names differing only in the presence of such a block name.
17577 2006-10-31 Thomas Quinot <quinot@adacore.com>
17578 Pablo Oliveira <oliveira@adacore.com>
17580 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17581 subprogram Ids, even if they are not yet assigned.
17582 (Build_Subprogram_Id): It is now this function that will take care of
17583 calling Assign_Subprogram_Ids if necessary.
17584 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17585 should be done only once they are assigned.
17586 (Build_From_Any_Function, case of tagged types): Add missing call to
17588 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17589 type for an RACW type.
17590 (Add_RACW_Features): When processing an RACW declaration for which the
17591 designated type is already frozen, enforce E.2.2(14) rules immediately.
17592 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17593 special reordering of controlling formals.
17595 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17596 associated stub type for an RACW type.
17598 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17600 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17601 fixed-point operations in an integer context, i.e. as operands of a
17602 conversion to an integer type, indicate that result must be rounded.
17604 2006-10-31 Robert Dewar <dewar@adacore.com>
17606 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17607 cases, pass the encoding method, since it is now required by the run
17610 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17611 assumption that Str'First = 1.
17612 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17613 it on to the Value_Wide_Wide_Character call.
17614 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17615 properly handles a string of the form quote-encoded_wide_char-quote.
17617 * s-wchcnv.adb: Minor reformatting
17619 2006-10-31 Javier Miranda <miranda@adacore.com>
17621 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17622 run-time membership test to ensure that the constructed object
17623 implements the target abstract interface.
17625 2006-10-31 Robert Dewar <dewar@adacore.com>
17627 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17628 Machine_Attribute pragma internally to implement the user pragma.
17629 Add processing for pragma Interface so that it is now completely
17630 equivalent to pragma Import.
17632 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17633 so that it can be applied to all entities, including record components
17634 and enumeration literals.
17635 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17636 priority ranges are correct, verify compatibility against task
17637 dispatching and locking policies, and if everything is correct an entry
17638 is added to the table containing priority specific dispatching entries
17639 for this compilation unit.
17640 (Delay_Config_Pragma_Analyze): Delay processing
17641 Priority_Specific_Dispatching pragmas because when processing the
17642 pragma we need to access run-time data, such as the range of
17643 System.Any_Priority.
17644 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17645 Allow pragma Unreferenced as a context item
17646 Add pragma Preelaborable_Initialization
17647 (Analyze_Pragma, case Interface): Interface is extended so that it is
17648 now syntactically and semantically equivalent to Import.
17649 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17650 insertion characters.
17651 Add handling for Pragma_Wide_Character_Encoding
17652 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17653 never supercedes a real restriction, and that a real restriction
17654 always supercedes a warning.
17655 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
17658 2006-10-31 Bob Duff <duff@adacore.com>
17659 Ed Schonberg <schonberg@adacore.com>
17660 Robert Dewar <dewar@adacore.com>
17662 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17663 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17664 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17666 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17667 type of the function containing a return statement, because the
17668 Return_Type field was removed. We now use the Return_Applies_To field.
17670 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17671 (Build_Task_Image_Decl): If procedure is not called from an
17672 initialization procedure, indicate that function that builds task name
17673 uses the sec. stack. Otherwise the enclosing initialization procedure
17674 will carry the indication.
17675 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17676 N_Object_Declaration instead.
17677 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17678 conditional dead code killed, and change implementation accordingly.
17679 (Insert_Actions): Add N_Return_Object_Declaration case.
17680 Correct comment to mention N_Extension_Aggregate node.
17681 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17682 attempts to save information for global variables which cannot be
17684 (Get_Current_Value_Condition): Handle conditions the other way round
17685 (constant on left). Also handle right operand of AND and AND THEN
17686 (Set_Current_Value_Condition): Corresponding changes
17687 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17688 (Get_Current_Value_Condition): Handle simple boolean operands
17689 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17690 (Get_Current_Value_Condition): If the variable reference is within an
17691 if-statement, does not appear in the list of then_statments, and does
17692 not come from source, treat it as being at unknown location.
17693 (Get_Current_Value_Condition): Enhance to allow while statements to be
17694 processed as well as if statements.
17695 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17697 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17698 of loop. This is safe now that we fixed Kill_Current_Values.
17699 (OK_To_Do_Constant_Replacement): Check whether current scope is
17700 Standard, before examining outer scopes.
17702 2006-10-31 Vincent Celier <celier@adacore.com>
17704 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17705 When True, apply VMS treatment to children of packages A, G, I and S.
17708 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17710 2006-10-31 Robert Dewar <dewar@adacore.com>
17711 Ed Schonberg <schonberg@adacore.com>
17713 * freeze.adb: Add handling of Last_Assignment field
17714 (Warn_Overlay): Supply missing continuation marks in error msgs
17715 (Freeze_Entity): Add check for Preelaborable_Initialization
17717 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17719 * g-expect.adb: Add Warnings (Off) to prevent new warning
17721 * lib-xref.adb: Add handling of Last_Assignment field
17722 (Generate_Reference): Centralize handling of pragma Obsolescent here
17723 (Generate_Reference): Accept an implicit reference generated for a
17724 default in an instance.
17725 (Generate_Reference): Accept a reference for a node that is not in the
17726 main unit, if it is the generic body corresponding to an subprogram
17729 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17731 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17733 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17735 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17736 use clauses, to avoid messages on packages used to qualify, and also
17737 to avoid messages from obsolescent units.
17738 (Warn_On_Useless_Assignments): Don't generate messages for imported
17739 and exported variables.
17740 (Warn_On_Useless_Assignments): New procedure
17741 (Output_Obsolescent_Entity_Warnings): New procedure
17742 (Check_Code_Statement): New procedure
17744 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
17745 Change name Is_Ada_2005 to Is_Ada_2005_Only
17746 (Last_Assignment): New field for useless assignment warning
17748 2006-10-31 Olivier Hainque <hainque@adacore.com>
17750 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17751 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17753 2006-10-31 Bob Duff <duff@adacore.com>
17754 Robert Dewar <dewar@adacore.com>
17755 Ed Schonberg <schonberg@adacore.com>
17757 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17758 Ada 95 mode, because it violates the new rules for AI-318.
17760 * g-awk.ads: Use overloaded subprograms in every case where we used to
17761 have a default of Current_Session. This makes the code closer to be
17762 correct for both Ada 95 and 2005.
17764 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17765 code, relying on the fact that the compiler generates a warning
17766 instead of an error in -gnatg mode.
17768 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17769 E_Return_Statement entity kind.
17770 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17772 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17773 report an error if the reserved word abstract has been previously found.
17774 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17776 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17777 parenthesized range attribute usage
17778 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17780 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17781 in the syntax for extended_return_statement. This is not in the latest
17782 RM, but the ARG is expected to issue an AI allowing this.
17783 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17784 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17785 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17786 P_Return_Statement): Parse the new syntax for extended_return_statement.
17788 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17789 Output_End_Missing): Add error-recovery code for the new
17790 extended_return_statement syntax; that is, the new E_Return entry on
17793 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17794 limited to nonlimited, because otherwise we violate the new Ada 2005
17795 rules about returning limited types in function Create_AST_Handler in
17798 * sem.adb (Analyze): Add cases for new node kinds
17799 N_Extended_Return_Statement and N_Return_Object_Declaration.
17801 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17802 type is in the same category as type of context before applying check,
17803 to prevent anomalies in instantiations.
17804 (Resolve_Aggregate): Remove test for limited components in aggregates.
17805 It's unnecessary in Ada 95, because if it has limited components, then
17806 it must be limited. It's wrong in Ada 2005, because limited aggregates
17808 (Resolve_Record_Aggregate): Move check for limited types later, because
17809 OK_For_Limited_Init requires its argument to have been resolved.
17810 (Get_Value): When copying the component default expression for a
17811 defaulted association in an aggregate, use the sloc of the aggregate
17812 and not that of the original expression, to prevent spurious
17813 elaboration errors, when the expression includes function calls.
17814 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17815 were missing. We also didn't handle qualified expressions. Now also
17816 allow function calls. Use new common routine OK_For_Limited_Init.
17817 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17818 with space can upper case letter).
17820 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17821 Has_Static_Discriminants flag
17822 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17823 type with discriminants.
17824 (Process_Range_Expr_In_Decl): Do validity checks on range
17825 (Build_Discriminant_Constraints): Use updated form of
17826 Denotes_Discriminant.
17827 (Process_Subtype): If the subtype is a private subtype whose full view
17828 is a concurrent subtype, introduce an itype reference to prevent scope
17830 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17831 Record_Type_Declaration): The functionality of the subprograms
17832 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17833 is now performed by a single routine.
17834 (Build_Derived_Record_Type): If the type definition includes an explicit
17835 indication of limitedness, then the type must be marked as limited here
17836 to ensure that any access discriminants will not be treated as having
17837 a local anonymous access type.
17838 (Check_Abstract_Overriding): Issue a detailed error message when an
17839 abstract subprogram was not overridden due to incorrect mode of its
17841 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17842 synchronized private extension declarations. Verify that the ancestor is
17843 a limited or synchronized interface or in the generic case, the ancestor
17844 is a tagged limited type or synchronized interface and all progenitors
17845 are either limited or synchronized interfaces.
17846 Derived_Type_Declaration): Check for presence of private extension when
17847 dealing with synchronized formal derived types.
17848 Process_Full_View): Enchance the check done on the usage of "limited" by
17849 testing whether the private view is synchronized.
17850 Verify that a synchronized private view is completed by a protected or
17852 (OK_For_Limited_Init_In_05): New function.
17853 (Analyze_Object_Declaration): Move check for limited types later,
17854 because OK_For_Limited_Init requires its argument to have been resolved.
17855 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17856 in order to alleviate the upward compatibility introduced by AI-318.
17857 (Constrain_Corresponding_Record): If the constraint is for a component
17858 subtype, mark the itype as frozen, to avoid out-of-scope references to
17859 discriminants in the back-end.
17860 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17861 this subprogram against wrong sources.
17862 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17863 discriminant of limited type completed with a protected type, when the
17864 discriminant is used to constrain a private component of the type, and
17865 expansion is disabled.
17866 (Find_Type_Of_Object): Do not treat a return subtype that is an
17867 anonymous subtype as a local_anonymous_type, because its accessibility
17868 level is the return type of the enclosing function.
17869 (Check_Initialization): In -gnatg mode, turn the error "cannot
17870 initialize entities of limited type" into a warning.
17871 (OK_For_Limited_Init): Return true for generated nodes, since it
17872 sometimes violates the legality rules.
17873 (Make_Incomplete_Declaration): If the type for which an incomplete
17874 declaration is created happens to be the currently visible entity,
17875 preserve the homonym chain when removing it from visibility.
17876 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17877 inherited subprograms.
17878 (Access_Definition): If this is an access to function that is the return
17879 type of an access_to_function definition, context is a type declaration
17880 and the scope of the anonymous type is the current one.
17881 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17882 incomplete subtype to the set of private dependents of the original
17884 (Constrain_Discriminated_Type): Emit an error message whenever an
17885 incomplete subtype is being constrained.

17926 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17927 call it with -static-libgcc, as there are some platforms, such as
17928 Darwin, where one of these two switches is compulsory to link.
17930 2006-10-31 Vincent Celier <celier@adacore.com>
17932 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17933 instead of ADA_PROJECT_PATH, for the project path.
17934 (Gnatls): When displaying the project path directories, use host dir
17937 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17938 names in the project path, as absolute paths may correspond to
17939 multi-valued VMS logical names.

17972 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
17974 (Layout_Variant_Record): Retrieve the discriminants from the entity
17975 rather than from the type definition, because in the case of a full
17976 type for a private type we need to take the discriminants from the
17978 (Layout_Component_List): When applying the Max operator to variants with
17979 a nonstatic size, check whether either operand is static and scale that
17980 operand from bits to storage units before applying Max.
17981 (Layout_Type): In VMS, if a C-convention access type has no explicit
17982 size clause (and does not inherit one in the case of a derived type),
17983 then the size is reset to 32 from 64.
17985 2006-10-31 Vincent Celier <celier@adacore.com>
17987 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
17988 its file has already been loaded, according to the unit being loaded,
17989 not to the current value of Multiple_Unit_Index.

18027 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18029 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18030 Process_Body_Clauses): If the context of a body includes a use clause
18031 for P.Q then a with_clause for P in the same body is not redundant,
18032 even if the spec also has a with_clause on P.
18033 Add missing continuation mark to error msg
18034 (Build_Limited_Views): A limited view of a type is tagged if its
18035 declaration includes a record extension.
18036 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18037 node, even if the subunit has errors. This avoids malfunction by
18038 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18039 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18040 generation of obsolescent messages for with statements (cannot do
18041 this too early, or we cannot implement avoiding the messages in the
18042 case of obsolescent units withing obsolescent units).
18043 (Install_Siblings): If the with_clause is on a remote descendant of
18044 an ancestor of the current compilation unit, find whether there is
18045 a sibling child unit that is immediately visible.
18046 (Remove_Private_With_Clauses): New procedure, invoked after completing
18047 the analysis of the private part of a nested package, to remove from
18048 visibility the private with_clauses of the enclosing package
18050 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18051 now centralized in Generate_Reference.
18052 (Install_Limited_Context_Clauses): Remove superfluous error
18053 message associated with unlimited view visible through use
18054 and renamings. In addition, at the point in which the error
18055 is reported, we add the backslash to the text of the error
18056 to ensure that it is reported as a single error message.
18057 Use new // insertion for some continuation messages
18058 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18059 to create implicit with_clause for parent unit mentioned in original
18060 limited_with_clause.
18061 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18062 unit is a child unit. For ASIS queries.
18063 (Analyze_Subunit): If the subunit appears within a child unit, make all
18064 ancestor child units directly visible again.

18079 a formal object declaration with an access definition or a subtype mark
18080 with a null exclusion.
18081 (P_Generic_Association): Handle association with box, and others_choice
18082 with box, to support Ada 2005 partially parametrized formal packages.
18084 2006-10-31 Robert Dewar <dewar@adacore.com>
18085 Javier Miranda <miranda@adacore.com>
18087 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18088 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18089 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18090 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18091 private extensions.
18092 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18093 to P_Interface_Type_Definition.
18094 (P_Interface_Type_Definition): Addition of one formal to report an error
18095 if the reserved word abstract has been previously found.
18096 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18097 object renaming declaration with an access definition or subtype mark
18098 with a possible null exclusion.

18117 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18120 2006-10-31 Vincent Celier <celier@adacore.com>
18122 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18123 on VMS, change "__" to '.' before checking the name.
18124 (Record_Ada_Source): Always add the source file name in the list of
18125 of sources, even if it is not the first time, as it is for another
18127 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18128 dot, instead of replacing only the first '_'.
18130 * prj-part.adb (Parse): Convert project file path to canonical form
18132 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18133 extended, the project id of the project extending it is recorded in its
18134 data, even when it has already been processed as an imported project.
18136 2006-10-31 Robert Dewar <dewar@adacore.com>
18138 * repinfo.adb (List_Entities): Don't list entities from renaming
18141 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18142 Robert Dewar <dewar@adacore.com>
18144 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18145 only a restriction warning is active for the given restriction. This is
18146 desirable because we do not want to modify code in the case where only
18148 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18149 causes overriding of real restrictions.
18150 Take advantage of new No_Restrictions constant.
18152 * raise.h: (__gnat_set_globals): Change profile.
18154 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18156 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18159 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18160 Move all the entities in obsolete package System.PolyORB_Interface to
18161 System.Partition_Interface.

18176 Javier Miranda <miranda@adacore.com>
18177 Gary Dismukes <dismukes@adacore.com>
18179 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18180 properly an attempt to apply Unchecked_Access to a protected operation.
18181 (OK_Self_Reference): New subprogram to check the legality of an access
18182 attribute whose prefix is the type of an enclosing aggregate.
18183 Generalizes previous mechanism to handle attribute references nested
18184 arbitrarily deep within the aggregate.
18185 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18186 can appear in an aggregate if this is a default-initialized aggregate
18187 for a self-referential type.
18188 (Resolve_Attribute, case Access): Ditto.
18189 Add support for new implementation defined attribute Stub_Type.
18190 (Eval_Attribute, case Attribute_Stub_Type): New case.
18191 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18192 (Stream_Attribute_Available): Implement using new subprogram from
18193 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18194 Has_Specified_Stream_Attribute flag.
18195 Disallow Storage_Size and Storage_Pool for access to subprogram
18196 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18197 access types of return subtypes in extended return statements. Remove
18198 accessibility checks on anonymous access types when Unchecked_Access is
18200 (Analyze_Attribute): Add support for the use of 'Class to convert
18201 a class-wide interface to a tagged type.
18202 Add support for the attribute Priority.
18203 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18204 whether the designated type is discriminated with a constrained partial
18205 view and require static matching in that case.
18206 Add local variable Des_Btyp. The Designated_Type
18207 of an access to incomplete subtype is either its non-limited view if
18208 coming from a limited with or its etype if regular incomplete subtype.
18210 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18211 Fix predicate to identify and allow cases of (expander-generated)
18212 references to tag of designated object of a RACW.
18213 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18214 non-static, and therefore cannot appear as a primary in a preelaborable
18216 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18217 Has_Read_Write_Attributes.
18218 (Has_Read_Write_Attributes): Reimplement in termes of
18219 Has_Stream_Attribute_Definition.
18220 (Missing_Read_Write_Attributes): When checking component types in a
18221 record, unconditionally call Missing_Read_Write_Attributes recursively
18222 (remove guard checking for Is_Record_Type / Is_Access_Type).
18224 2006-10-31 Robert Dewar <dewar@adacore.com>
18226 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18227 useless assignments here and conditionalize it on absence of exception
18229 (Analyze_Exception_Handlers): Small code reorganization of error
18230 detection code, for new handling of formal packages.
18232 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18233 Hristian Kirtchev <kirtchev@adacore.com>
18235 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18236 that has been constant-folded, preserve information of original tree,
18238 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18239 generated private extension declaration if the formal derived type is
18240 synchronized. Carry synchronized present over to the generated private
18242 (Validate_Derived_Type_Instance): Ensure that the actual of a
18243 synchronized formal derived type is a synchronized tagged type.
18244 (Instantiate_Formal_Package): When creating the instantiation used to
18245 validate the actual package of a formal declared without a box, check
18246 whether the formal itself depends on a prior actual.
18247 (Instantiate_Formal_Subprogram): Create new entities for the defining
18248 identifiers of the formals in the renaming declaration, for ASIS use.
18249 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18250 a renaming declaration or a subtype declaration for an actual in an
18251 instance, capture location information of declaration in generic, for
18253 (Instantiate_Formal_Package): Add comments on needed additional tests.
18254 AI-317 (partial parametrization) is fully implemented.
18255 (Validate_Private_Type_Instance): Add check for actual which
18256 must have preelaborable initialization
18257 Use new // insertion for some continuation messages
18258 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18259 Default_Expression. Add type retrieval when the declaration has an
18260 access definition. Update premature usage of incomplete type check.
18261 (Check_Access_Definition): New subsidiary routine. Check whether the
18262 current compilation version is Ada 05 and the supplied node has an
18264 (Instantiate object): Alphabetize local variables. Handle the creation
18265 of new renaming declarations with respect to the kind of definition
18266 used - either an access definition or a subtype mark. Guard against
18267 unnecessary error message in the context of anonymous access types after
18268 they have been resolved. Add check for required null exclusion in a
18269 formal object declaration.
18270 (Switch_View): A private subtype of a non-private type needs to be
18271 switched (the base type can have been switched without its private
18272 dependents because of the last branch of Check_Private_View.
18273 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18275 (Instantiate_Type): Emit an error message whenever a class-wide type of
18276 a tagged incomplete type is used as a generic actual.
18277 (Find_Actual_Type): Extend routine to handle a component type in a child
18278 unit that is imported from a formal package in a parent.
18279 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18280 agree on constrainedness, rather than checking against ultimate ancestor
18281 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18282 generic body, for navigation purposes.
18284 2006-10-31 Robert Dewar <dewar@adacore.com>
18285 Thomas Quinot <quinot@adacore.com>
18287 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18289 (New_Stream_Subprogram): When processing an attribute definition clause
18290 for a stream-oriented subprogram, record an entity node occurring at
18291 the point of clause to use for checking the visibility of the clause,
18292 as defined by 8.3(23) as amended by AI-195.
18293 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18294 New_Stream_Function and New_Stream_Procedure.
18295 (New_Stream_Function, New_Stream_Procedure): Removed.
18296 (Analyze_Attribute_Definition_Clause, case Address): Check new
18297 Alignment_Check check
18299 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18300 Javier Miranda <miranda@adacore.com>
18301 Robert Dewar <dewar@adacore.com>
18303 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18304 generate the same errors compiling under -gnatc.
18305 (Try_Object_Operation): If no candidate interpretation succeeds, but
18306 there is at least one primitive operation with the right name, report
18307 error in call rather than on a malformed selected component.
18308 (Analyze_Selected_Component): If the prefix is an incomplete type from
18309 a limited view, and the full view is available, use the full view to
18310 determine whether this is a prefixed call to a primitive operation.
18311 (Operator_Check): Verify that a candidate interpretation is a binary
18312 operation before checking the type of its second formal.
18313 (Analyze_Call): Add additional warnings for function call contexts not
18315 (Analyze_Allocator): Move the check for "initialization not allowed for
18316 limited types" after analyzing the expression. This is necessary,
18317 because OK_For_Limited_Init looks at the structure of the expression.
18318 Before analysis, we don't necessarily know what sort of expression it
18319 is. For example, we don't know whether F(X) is a function call or an
18320 indexed component; the former is legal in Ada 2005; the latter is not.
18321 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18322 were missing. We also didn't handle qualified expressions. Now also
18323 allow function calls. Use new common routine OK_For_Limited_Init.
18324 (Analyze_Type_Conversion): Do not perform some legality checks in an
18325 instance, because the error message will be redundant or spurious.
18326 (Analyze_Overloaded_Selected_Component): Do not do style check when
18327 setting an entity, since we do not know it is the right entity yet.
18328 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18329 (Analyze_Overloaded_Selected_Component): Same change
18330 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18331 since regular incomplete subtypes are transformed into corresponding
18332 subtypes of their full views.
18333 (Complete_Object_Operation): Treat name of transformed subprogram call
18334 as coming from source, for browsing purposes.
18335 (Try_Primitive_Operation): If formal is an access parameter, compare
18336 with base type of object to determine whether it is a primitive
18338 (Operator_Check): If no interpretation of the operator matches, check
18339 whether a use clause on any candidate might make the operation legal.

18350 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18351 (Process_Bounds): If the bounds are integer literals that result from
18352 constant-folding, and they carry a user-defined type, preserve that type
18353 rather than treating this as an integer range.
18354 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18355 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18356 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18357 left hand side of assignment.

18361 not just identifiers.
18362 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18363 or AND THEN for possible tracking.
18364 (Analyze_Iteration_Scheme): Check for setting Current_Value for the

18368 Hristian Kirtchev <kirtchev@adacore.com>
18369 Bob Duff <duff@adacore.com>
18371 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18372 procedure cannot be a protected operation (it is a basic_declaration,
18373 not a subprogram_declaration).
18374 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18375 Subp. Add logic for entry processing.
18376 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.

18390 pass new parameters. Add support for adding the new extra access formal
18391 for functions whose calls are treated as build-in-place.
18392 (Analyze_A_Return_Statement): Correct casing in error message.
18393 Move Pop_Scope to after Analyze_Function_Return, because an extended
18394 return statement really is a full-fledged scope. Otherwise, visibility
18395 doesn't work right. Correct use of "\" for continuation messages.
18396 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18397 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18398 the node doesn't get properly marked as analyzed.
18399 (Analyze_Subprogram_Body): If subprogram is a function that returns
18400 an anonymous access type that denotes a task, build a Master Entity
18402 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18403 proper usage of null exclusion in a result definition.
18404 (Process_Formals): Code cleanup and new error message.

18412 homonym chain if it corresponds with an abstract interface primitive.
18413 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18414 call to the synthesized predicate Is_Incomplete_Type.

18417 (Analyze_Subprogram_Declaration): Check that abstract interface
18418 primitives are abstract or null.
18419 (Analyze_Subprogram_Specification): Remove previous check for abstract
18420 interfaces because it was not complete.
18421 (Has_Interface_Formals): Removed.

18426 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18427 of Analyze_Package_Body, to create Itype references for anonymous
18428 access types created in the package declaration, whose designated types
18429 may have only a limited view.
18430 (Analyze_Package_Specification): For the private part of a nested
18431 package, install private_with_clauses of enclosing compilation unit if
18432 we are in its visible part.
18433 (Declare_Inherited_Private_Subprograms): Complete barrier
18434 to ensure that the primitive operation has an alias to some parent
18435 primitive. This is now required because, after the changes done for the
18436 implementation of abstract interfaces, the contents of the list of
18437 primitives has entities whose alias attribute references entities of
18438 such list of primitives.
18439 (Analyze_Package_Specification): Simplify code that handles parent units
18440 of instances and formal packages.
18441 (Uninstall_Declarations): Check the convention consistency among
18442 primitive overriding operations of a tagged record type.

18456 as potentially use-visible.
18457 (Find_Type): Handle the case of an attribute reference for
18458 implementation defined attribute Stub_Type (simply let the analysis of
18459 the attribute reference rewrite it).
18460 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18461 type that appears in a Use_Type clause.
18462 (Analyze_Object_Renaming): Add support for renaming of the Priority
18464 (Find_Type): In Ada 2005, a task type can be used within its own body,
18465 when it appears in an access definition.
18466 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18467 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18468 in a formal object declaration or in a subtype declaration.
18469 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18470 (Check_Null_Exclusion): New local routine to
18471 Analyze_Subprogram_Renaming. Check whether the formals and return
18472 profile of a renamed subprogram have required null exclusions when
18473 their counterparts of the renaming already impose them.
18474 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18475 Determine whether an entity is inside a generic scope.
18476 (In_Open_Scope): First pass of documentation update.
18477 (Find_Expanded_Name): Add support for shadow entities associated with
18478 limited withed packages. This is required to handle nested packages.
18479 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18480 that makes a renaming of a limited withed package illegal.
18482 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18483 Ed Schonberg <schonberg@adacore.com>
18485 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18486 Check_Overriding_Indicator.
18487 (Analyze_Task_Definition): Ditto.
18488 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18489 (Check_Overriding_Indicator): To find overridden interface operation,
18490 examine only homonyms that have an explicit subprogram declaration, not
18491 inherited operations created by an unrelated type derivation.
18492 (Check_Overriding_Indicator): When checking for the presence of "null"
18493 in a procedure, ensure that the queried node is a procedure

18496 type when the formal is an access to variable.
18497 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18498 (Analyze_Task_Type): Same addition
18499 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to

18511 of a call to a function that dispatches on access result.
18512 (Check_Dispatching_Operation): In case of late overriding of a primitive
18513 that covers abstract interface subprograms we register it in all the
18514 secondary dispatch tables associated with abstract interfaces.
18515 (Check_Dispatching_Call): Add check that a dispatching call is not made
18516 to a function with a controlling result of a limited type. This is a
18517 current implementation restriction.
18518 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18519 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18520 argument is an interface type that is a generic formal.
18521 (Is_Interface_Subprogram): Removed.
18522 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18523 operation, check the formals to handle the case in which it is
18524 associated with an abstract interface type.

18542 Javier Miranda <miranda@adacore.com>
18544 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve

18547 the context of generic instantiation.
18548 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18549 abstract interface types; this is required to handle concurrent types
18550 with discriminants and abstract interface types.

18566 qualification from an expression. There are numerous places where this
18567 ought to be used, but we currently only deal properly with zero or one
18569 (In_Instance); The analysis of the actuals in the instantiation of a
18570 child unit is not within an instantiation, even though the parent
18571 instance is on the scope stack.

18574 (Check_Obsolescent): Removed
18575 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

18653 (N_Extended_Return_Statement): New node for extended_return_statement
18655 (N_Return_Object_Declaration): New node for part of

18829 * a-rttiev.ads, a-rttiev.adb:
18830 This is a significant redesign primarily for the sake of automatic
18831 timer task termination but also to fix a design flaw.
18832 Therefore we are now using an RTS lock, instead of a protected
18833 object, to provide mutual exclusion to the queue of pending events
18834 and the type Timing_Event is no longer a protected type.

19340 we must pass the work to the expander to generate the required code to
19341 evaluate the conversion at run-time.
19342 (Resolve_Equality_Op): Do not apply previous

19682 other basic tools. The full version that includes the Ada 2005 stuff

20020 junk obsolete Immediate_Errors flag.
20021 (Tree_Read): Change the way of reading Tree_Version_String - now we

20112 (Freeze_Record_Type): Do not generate the tables associated with
20113 timed and conditional dispatching calls through synchronized
20114 interfaces if compiling under No_Dispatching_Calls restriction.
20115 When compiling for Ada 2005, for a nonabstract
20116 type with a null extension, call Make_Controlling_Function_Wrappers
20117 and insert the wrapper function declarations and bodies (the latter
20118 being appended as freeze actions).
20119 (Predefined_Primitive_Bodies): Do not generate the bodies of the

20121 dispatching calls through synchronized interfaces if we are
20122 compiling under No_Dispatching_Calls.

20124 service is available before generating a call.
20125 (Make_Controlling_Function_Wrappers): New procedure.
20126 (Expand_N_Full_Type_Declaration): Create a class-wide master for

20128 tasks that implement such limited interface.
20129 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20130 procedure spec and body of the Offset_To_Top function that is generated
20131 when the parent of a type with discriminants has secondary dispatch
20133 (Init_Secondary_Tags): Handle the case in which the parent of the type
20134 containing secondary dispatch tables has discriminants to generate the
20135 correct arguments to call Set_Offset_To_Top.

20138 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20139 Add Wide_[Wide_]Expanded_Name.
20140 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20141 the same functionality of Get_Prim_Op_Address but applied to predefined
20142 primitive operations because the pointers to the predefined primitives
20143 are now saved in a separate table.
20144 (Parent_Size): Modified to get access to the separate table of primitive
20145 operations or the parent type.
20146 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20147 functionality of Set_Prim_Op_Address but applied to predefined primitive
20149 (Set_Signature): New subprogram used to store the signature of a DT.
20150 (Displace): If the Offset_To_Top value is not static then call the
20151 function generated by the expander to get such value; otherwise use
20152 the value stored in the table of interfaces.
20153 (Offset_To_Top): The type of the actual has been changed to Address to
20154 give the correct support to tagged types with discriminants. In this
20155 case this value is stored just immediately after the tag field.
20156 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20157 offset_to_top value is static and hence pass this value to the run-time
20158 to store it in the table of interfaces, or else if this value is dynamic
20159 and then pass to the run-time the address of a function that is
20160 generated by the expander to provide this value for each object of the
20163 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20164 (Default_Prim_Op_Count): New entity

20175 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20176 in a subprogram are wrapped in a cleanup block, indicate that the
20177 subprogram contains an inner block with an exception handler.
20178 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20179 Adjust call is for a newly-allocated object. In that case we must not
20180 assume that the finalization list chain pointers are correct (since they
20181 come from a bit-for-bit copy of the original object's pointers) so if
20182 the attach level would otherwise be zero (no change), we set it to 4
20183 instead to cause the pointers to be reset to null.
20185 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20186 reset chain pointers to null.
20188 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20190 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20191 string, and the context requires a loop for the assignment (e.g.
20192 because the left-hand side is packed), generate a unique name for the
20193 temporary that holds the string, to prevent spurious name clashes.

20197 Robert Dewar <dewar@adacore.com>
20198 Gary Dismukes <dismukes@adacore.com>
20200 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20201 return unconstrained arrays.
20203 (Expand_Call): An indirect call through an access parameter of a
20204 protected operation is not a protected call.
20205 Add circuit to raise CE in Ada 2005 mode following call
20206 to Raise_Exception.
20207 (Register_DT_Entry): Do nothing if
20208 the run-time does not give support to abstract interfaces.
20209 (Freeze_Subprogram): In case of dispatching operations, do not generate
20210 code to register the operation in the dispatch table if the source
20211 is compiled with No_Dispatching_Calls.
20212 (Register_Predefined_DT_Entry): Generate code that calls the new
20213 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20214 Set_Prim_Op_Address.
20216 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20217 on array assignments if the right-hand side is a function call that has
20218 been inlined. Check is performed on the assignment in the block.
20219 (Process_Bounds): If bounds and range are overloaded, apply preference
20220 rule for root operations to disambiguate, and diagnose true ambiguity.
20221 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20222 a tag-indeterminate right-hand side even when Expander_Active is True.
20223 Needed to ensure that dispatching calls to T'Input are allowed and
20224 get the tag of the target class-wide object.
20226 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20227 an inherited primitive operation that already overrides several
20228 abstract interface primitives. For transitivity, the new entity must
20229 also override all the abstract interface primitives covered by the
20230 inherited overriden primitive.
20231 Emit warning if new entity differs from homograph in same scope only in
20232 that one has an access parameter and the other one has a parameter of
20233 a general access type with the same designated type, at the same
20234 position in the signature.
20235 (Make_Inequality_Operator): Use source locations of parameters and
20236 subtype marks from corresponding equality operator when creating the
20237 tree structure for the implicit declaration of "/=". This does not
20238 change anything in behaviour except that the decoration of the
20239 components of the subtree created for "/=" allows ASIS to get the
20240 string images of the corresponding identifiers.
20241 (Analyze_Return_Statement): Remove '!' in warning message.
20242 (Check_Statement_Sequence): Likewise.
20243 (Analyze_Subprogram_Body): For an access parameter whose designated type
20244 is an incomplete type imported through a limited_with clause, use the
20245 type of the corresponding formal in the body.
20246 (Check_Returns): Implicit return in No_Return procedure now raises
20247 Program_Error with a compile time warning, instead of beging illegal.
20248 (Has_Single_Return): Function returning unconstrained type cannot be
20249 inlined if expression in unique return statement is not an identifier.
20250 (Build_Body_To_Inline): It is possible to inline a function call that
20251 returns an unconstrained type if all return statements in the function
20252 return the same local variable. Subsidiary procedure Has_Single_Return
20253 verifies that the body conforms to this restriction.
20255 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20256 same type, and one of them is of an anonymous access type, convert
20257 the other operand to it, so that this is a valid binary operation for
20259 (Resolve_Type_Conversion): Handle subtypes of protected types and
20260 task types when accessing to the corresponding record type.
20261 (Resolve_Allocator): Add '\' in 2-line warning message.
20262 Remove '!' in warning message.
20263 (Resolve_Call): Add '\' in 2-line warning message.
20264 (Valid_Conversion): Likewise.
20265 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20266 resulting type may be an access type with an implicit dereference.
20267 Obtain the proper component from the designated type.
20268 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20269 given by an expanded name with prefix Standard, when the operands are
20270 of an anonymous access type.
20271 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20272 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20273 prefix of the expression is not of an incomplete type. Allows full
20274 diagnoses of all semantic errors.
20275 (Resolve_Actuals): If the actual is an allocator whose directly
20276 designated type is a class-wide interface we build an anonymous
20277 access type to use it as the type of the allocator. Later, when
20278 the subprogram call is expanded, if the interface has a secondary
20279 dispatch table the expander will add a type conversion to force
20280 the displacement of the pointer.
20281 (Resolve_Call): If a function that returns an unconstrained type is
20282 marked Inlined_Always and inlined, the call will be inlined and does
20283 not require the creation of a transient scope.
20284 (Check_Direct_Boolean_Op): Removed
20285 (Resolve_Comparison_Op): Remove call to above
20286 (Resolve_Equality_Op): Remove call to above
20287 (Resolve_Logical_Op): Inline above, since this is only call.
20288 (Valid_Conversion): Handle properly conversions between arrays of
20289 convertible anonymous access types.
20292 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20293 the literal in an unchecked conversion, because GCC 4.x needs a static
20294 value for a string bound.
20296 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20297 Hristian Kirtchev <kirtchev@adacore.com>
20299 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20300 components of the corresponding record, take into account component
20301 definitions that are access definitions.
20302 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20303 procedure is not considered a dispatching call and will be expanded
20306 2006-02-13 Javier Miranda <miranda@adacore.com>
20308 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20309 controlling argument of the dispatching call is an abstract interface
20310 class-wide type then we use it directly.
20311 Check No_Dispatching_Calls restriction.
20312 (Default_Prim_Op_Position): Remove the code that looks for the last
20313 entity in the list of aliased subprograms. This code was wrong in
20315 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20316 when the source is compiled with the No_Dispatching_Calls restriction.
20317 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20318 if we are compiling with restriction No_Dispatching_Calls.
20319 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20320 subprograms if we are compiling under No_Dispatching_Calls restriction.
20321 (Make_DT): Generate a dispatch table with a single dummy entry if
20322 we are compiling with the No_Dispatching_Calls restriction. In
20323 addition, in this case we don't generate code that calls to the
20324 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20325 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20326 of this subprogram if compiling with the No_Dispatching_Calls
20328 (Expand_Type_Conversion): Instead of using the actual parameter,
20329 the argument passed as parameter to the conversion function was
20330 erroneously referenced by the expander.
20331 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20332 Set_Predefined_Primitive_Op_Address and Set_Signature.
20333 (Expand_Dispatching_Call): Generate call to
20334 Get_Predefined_Prim_Op_Address for predefined primitives.
20335 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20336 predefined primitives.
20337 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20338 primitives we reserve one dummy entry to ensure that the tag does not
20339 point to some memory that is associated with some other object. In
20340 addition, remove all the old code that generated the assignments
20341 associated with the signature of the dispatch table and replace them
20342 by a call to the new subprogram Set_Signature.
20343 (Set_All_DT_Position): Change the algorithm because now we have a
20344 separate dispatch table associated with predefined primitive operations.
20345 (Expand_Interface_Conversion): In case of non-static offset_to_top
20346 add explicit dereference to get access to the object after the call
20347 to displace the pointer to the object.
20348 (Expand_Interface_Thunk): Modify the generation of the actual used
20349 in the calls to the run-time function Offset_To_Top to fulfil its
20351 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20353 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20355 * exp_dist.adb (Copy_Specification): For access parameters, copy
20356 Null_Exclusion flag, which will have been set for stream subprograms
20359 2006-02-13 Pascal Obry <obry@adacore.com>
20361 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20362 previous implementation was using the C runtime spawnve routine but
20363 the corresponding wait was using directly the Win32 API. This was
20364 causing some times a lock when waiting for an event using
20365 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20366 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20367 API fixes this problem.
20369 2006-02-13 Robert Dewar <dewar@adacore.com>
20371 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20379 array reference that is an explicit dereference, mark the converted
20380 (packed) array reference as analyzed to prevent a forthcoming
20381 reanalysis from resetting its type to the original (non-packed) array
20384 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20385 Javier Miranda <miranda@adacore.com>
20386 Eric Botcazou <ebotcazou@adacore.com>
20388 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20389 Is_Predefined_Primitive_Operation): When
20390 searching for the predefined equality operator, verify that operands
20391 have the same type.
20392 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20393 for the last entity in the list of aliased subprograms. This code
20394 was wrong in case of renamings.
20395 (Set_Renamed_Subprogram): New procedure
20396 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20397 Exp_Type constant computed when entering this subprogram.
20398 (Known_Null): New function
20399 (OK_To_Do_Constant_Replacement): New function
20400 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20401 (Side_Effect_Free): An attribute reference 'Input is not free of
20402 side effect, unlike other attributes that are functions. (from code
20404 (Remove_Side_Effects): Expressions that involve packed arrays or records
20405 are copied at the point of reference, and therefore must be marked as
20406 renamings of objects.
20407 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20408 not a dispatching operation.
20411 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20412 elementary types in all cases.
20414 2006-02-13 Javier Miranda <miranda@adacore.com>
20416 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20417 task types when accessing to the corresponding record type.
20418 Remove '!' in warning message.
20420 2006-02-13 Olivier Hainque <hainque@adacore.com>
20422 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20423 to avoid useless and space inefficient overalignments on targets where
20424 Max_Alignment is larger than 16.
20426 2006-02-13 Pascal Obry <obry@adacore.com>
20428 * g-catiio.adb (Sec_Number): New type used to compute the number of
20429 seconds since 1-1-1970.
20430 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20431 negative numbers (years, months...) it is better to have a Natural here.
20433 (Image) [Number]: Change parameter from Long_Integer to Number.
20434 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20435 overflow for dates past year 2038.
20437 2006-02-13 Matthew Heaney <heaney@adacore.com>
20439 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20442 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20444 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20446 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20447 finalization can occur normally.
20449 2006-02-13 Vincent Celier <celier@adacore.com>
20451 * gnatcmd.adb (Rules_Switches): New table
20452 (Add_To_Rules_Switches): New procedure
20453 (GNATCmd): For command CHECK, put all options following "-rules" in the
20454 Rules_Switches table. Append these -rules switches after the -cargs
20457 2006-02-13 Robert Dewar <dewar@adacore.com>
20459 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20460 These two cases were generating incorrect output, and if this unit
20461 was built with checks on, generated a discriminant mismatch constraint
20464 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20465 Robert Dewar <dewar@adacore.com>
20467 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20468 view is an array type, indicate the component type as well, for
20469 navigation purposes.
20470 (Generate_Reference): Don't consider array ref on LHS to be a case
20471 of violating pragma Unreferenced.
20472 Do not give Ada 2005 warning except on real reference.
20474 2006-02-13 Vincent Celier <celier@adacore.com>
20476 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20477 main source, add switch -mdebug-main=_ada_ so that the executable can
20478 be debugged by the standard VMS debugger.
20479 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20480 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20481 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20482 of the last source, as the binding and linking phases are never
20484 Set all executable obsolete when rebuilding a library.
20486 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20489 2006-02-13 Javier Miranda <miranda@adacore.com>
20492 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20493 code to improve the error message reported when the program has
20494 declarations of abstract interface types and it is not compiled with
20495 the -gnat05 switch.
20496 (P_Access_Definition): Reorganize the code to improve the error
20497 message reported when the new Ada 2005 syntax for anonymous
20498 access types is used and the program is not compiled with the
20501 2006-02-13 Robert Dewar <dewar@adacore.com>
20503 * par-ch6.adb, style.ads, styleg.adb, styleg.ads, stylesw.adb,
20504 stylesw.ads, usage.adb, vms_data.ads: Implement -gnatyI switch
20507 2006-02-13 Javier Miranda <miranda@adacore.com>
20509 * par-endh.adb (Explicit_Start_Label): Add code to protect the parser

20512 2006-02-13 Vincent Celier <celier@adacore.com>
20514 * prj.adb (Reset): Initialize the first element of table Namings with
20515 the standard naming data.
20517 2006-02-13 Vincent Celier <celier@adacore.com>
20519 * prj.ads (Error_Warning): New enumeration type
20521 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20522 unknown, use the location of the project to report the error.
20523 (When_No_Sources): New global variable
20524 (Report_No_Ada_Sources): New procedure
20525 (Check): New parameter When_No_Sources. Set value of global variable

20536 Call Recursive_Check with parameter When_No_Sources.
20537 (Recursive_Check): New parameter When_No_Sources. Call itself and
20538 Prj.Nmsc.Check with parameter When_No_Sources.
20539 (Process): New parameter When_No_Sources. Call Check with parameter
20541 (Copy_Package_Declarations): New procedure to copy renamed parameters
20542 and setting the location of the declared attributes to the location
20543 of the renamed package.
20544 (Process_Declarative_Items): Call Copy_Package_Declarations for renamed
20547 2006-02-13 Vincent Celier <celier@adacore.com>
20549 * prj-makr.adb (Make): Preserve the comments from the original project
20551 When removing nodes (attributes Source_Dirs, Source_Files,
20552 Source_List_File and package Naming), save the comments and attach the
20553 saved comments to the newly created nodes.
20554 Do not add a with clause for the naming package if one already exists.

20566 (Check_Dispatching_Operation): Do not generate code to register the
20567 operation in the dispatch table if the source is compiled with
20568 restriction No_Dispatching_Calls.

20570 No_Return procedure with procedure that is not No_Return
20571 (Check_Dispatching_Call): Suppress the check for an abstract operation
20572 when the original node of an actual is a tag-indeterminate attribute
20573 call, since the attribute, which must be 'Input, can never be abstract.
20574 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20575 call to the Input attribute (even when rewritten).
20576 (Propagate_Tag): Augment comment to indicate the possibility of a call
20577 to an Input attribute.
20579 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20580 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
20582 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
20583 No_Wide_Characters is no longer partition-wide
20584 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
20587 2006-02-13 Douglas Rupp <rupp@adacore.com>
20589 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20591 2006-02-13 Javier Miranda <miranda@adacore.com>
20593 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20594 handles default-initialized components to keep separate the management
20595 of this feature but also avoid the unrequired resolution and
20596 expansion of components that do not have partially initialized
20598 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20599 (Check_Bounds): Likewise.
20600 (Check_Length): Likewise.
20602 2006-02-13 Javier Miranda <miranda@adacore.com>
20603 Ed Schonberg <schonberg@adacore.com>
20605 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20606 abstract interface type call analyze_and_resolve to expand the type
20607 conversion into the corresponding displacement of the
20608 reference to the base of the object.
20609 (Eval_Attribute, case Width): For systems where IEEE extended precision
20610 is supported, the maximum exponent occupies 4 decimal digits.
20611 (Accessibility_Message): Add '\' in 2-line warning message.
20612 (Resolve_Attribute): Likewise.
20613 (case Attribute_Access): Significantly revise checks
20614 for illegal access-to-subprogram Access attributes to properly enforce
20615 the rules of 3.10.2(32/2).
20616 Diagnose use of current instance with an illegal attribute.
20618 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20620 (Enclosing_Generic_Unit): New function to return a node's innermost
20621 enclosing generic declaration node.
20622 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20623 (Type_Access_Level): The accessibility level of anonymous acccess types
20624 associated with discriminants is that of the current instance of the
20625 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20626 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20627 (Kill_Current_Values_For_Entity): New function
20628 (Enter_Name): Change formal type to Entity_Id
20630 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20631 Ed Schonberg <schonberg@adacore.com>
20632 Gary Dismukes <dismukes@adacore.com>
20634 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20635 Analyze_Compilation_Unit.
20636 Detect and warn on redundant with clauses detected in a package spec
20637 and/or body when -gnatwr is used.
20638 (Analyze_Context): Analyze config pragmas before other items
20639 (Install_Context_Items): Don't analyze config pragmas here
20640 (Install_Limited_Withed_Unit): Set limited entity of package in
20641 with_clause so that cross-reference information or warning messages on
20642 unused packages can be properly generated
20643 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20644 has Error_Posted set. Prevent infinite loops in illegal programs.
20645 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20646 to the point of the error test requiring the current unit to be private.
20647 This ensures that private with clauses are not exempted from the basic
20648 checking for being a descendant of the same library unit parent as a
20649 withed private descendant unit.
20650 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20651 handle private with clauses properly, as well as to account for cases
20652 where the withed unit is a public descendant of a private ancestor
20653 (in which case the current unit must be a descendant of the private
20654 ancestor's parent). The spec comments were updated accordingly. Also,
20655 the old error message in this subprogram was replaced with error
20656 messages that mirror the errors tested and reported by
20657 Check_Private_Child_Unit.
20658 Parameter and variable names improved for readability.
20659 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20660 private as the precondition for calling
20661 Check_Private_Limited_Withed_Unit since that subprogram has been
20662 revised to test public units as well as private units.

20667 Javier Miranda <miranda@adacore.com>
20669 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20670 that Scope_Stack.First = 1.
20671 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20672 were not always properly handled previously.
20673 (Formal_Entity): Complete rewrite, to handle properly some complex case
20674 with multiple levels of parametrization by formal packages.
20675 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20676 to the corresponding derived type declaration for proper semantics.
20678 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20679 (Check_Component): Enforce restriction on components of
20680 unchecked_unions: a component in a variant cannot contain tasks or
20682 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20684 Add pragma Ada_2005 (synonym for Ada_05)
20685 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20686 were not always properly handled previously.
20687 Document that pragma Propagate_Exceptions has no effect
20688 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20689 (Set_Convention_From_Pragma): Check that if a convention is
20690 specified for a dispatching operation, then it must be
20691 consistent with the existing convention for the operation.
20692 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20693 longer required to specify an vtable-ptr component in the record. For
20694 compatibility reasons we leave the support for the previous definition.
20695 (Analyze_Pragma, case No_Return): Allow multiple arguments
20697 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20698 non-overrideen inherited operation with a controlling result as
20699 illegal only its implicit declaration comes from the derived type
20700 declaration of its result's type.
20701 (Check_Possible_Deferred_Completion): Relocate the object definition
20702 node of the subtype indication of a deferred constant completion rather
20703 than directly analyzing it. The analysis of the generated subtype will
20704 correctly decorate the GNAT tree.
20705 (Record_Type_Declaration): Check whether this is a declaration for a
20706 limited derived record before analyzing components.
20707 (Analyze_Component_Declaration): Diagnose record types not explicitly
20708 declared limited when a component has a limited type.
20709 (Build_Derived_Record_Type): Code reorganization to check if some of
20710 the inherited subprograms of a tagged type cover interface primitives.
20711 This check was missing in case of a full-type associated with a private
20713 (Constant_Redeclaration): Check that the subtypes of the partial and the
20714 full view of a constrained deferred constant statically match.
20715 (Mentions_T): A reference to the current type in an anonymous access
20716 component declaration must be an entity name.
20717 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20718 class_wide type to refer to full type, not to the incomplete one.
20719 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20720 available. Required to give support to the certified run-time.
20721 (Analyze_Component_Declaration): In case of anonymous access components
20722 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20723 (Process_Discriminants): For an access discriminant, use the
20724 discriminant specification as the associated_node_for_itype, to
20725 simplify accessibility checks.

20728 Javier Miranda <miranda@adacore.com>
20730 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20731 abstract interpretations on an operator, remove interpretations that
20732 yield Address or a type derived from it, if one of the operands is an
20734 (Try_Object_Operation.Try_Primitive_Operation,
20735 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20736 location when creating the new reference to a primitive or class-wide
20737 operation as a part of rewriting a subprogram call.
20738 (Try_Primitive_Operations): If context requires a function, collect all
20739 interpretations after the first match, because there may be primitive
20740 operations of the same type with the same profile and different return
20741 types. From code reading.
20742 (Try_Primitive_Operation): Use the node kind to choose the proper
20743 operation when a function and a procedure have the same parameter
20745 (Complete_Object_Operation): If formal is an access parameter and prefix
20746 is an object, rewrite as an Access reference, to match signature of
20747 primitive operation.
20748 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20749 by an expanded name with prefix Standard, when the operands are of an
20750 anonymous access type.
20751 (Remove_Abstract_Operations): If the operation is abstract because it is
20752 inherited by a user-defined type derived from Address, remove it as
20753 well from the set of candidate interpretations of an overloaded node.
20754 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20757 2006-02-13 Bob Duff <duff@adacore.com>
20759 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20760 redundant use clauses.
20761 In particular, if the scope of two use clauses overlaps, but one is not
20762 entirely included in the other, we should not warn. This can happen
20763 with nested packages.
20764 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20765 reported errors. The bug was reported when the compiler was built
20766 with assertions enabled.
20767 (Find_Type): If the node is a 'Class reference and the prefix is a
20768 synchronized type without a corresponding record, return the type
20771 2006-02-13 Javier Miranda <miranda@adacore.com>
20773 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20774 if this is the full-declaration associated with a private declaration
20775 that implement interfaces, then the private type declaration must be
20777 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20778 as aliased. The use of the 'access attribute is not available for such
20779 object (for this purpose the object should be explicitly marked as
20780 aliased, but being an anonymous type this is not possible).
20782 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20783 Robert Dewar <dewar@adacore.com>
20785 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20786 compilation unit is an elaboration scope.
20787 (Add_Task_Proc): Add '\' in 2-line warning message.
20788 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20790 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20791 Javier Miranda <miranda@adacore.com>
20793 * sem_type.adb (Write_Overloads): Improve display of candidate
20795 (Add_One_Interp): Do not add to the list of interpretations aliased
20796 entities corresponding with an abstract interface type that is an
20797 immediate ancestor of a tagged type; otherwise we have a dummy
20798 conflict between this entity and the aliased entity.
20799 (Disambiguate): The predefined equality on universal_access is not
20800 usable if there is a user-defined equality with the proper signature,
20801 declared in the same declarative part as the designated type.
20802 (Find_Unique_Type): The universal_access equality operator defined under
20803 AI-230 does not cover pool specific access types.
20804 (Covers): If one of the types is a generic actual subtype, check whether
20805 it matches the partial view of the other type.
20807 2006-02-13 Thomas Quinot <quinot@adacore.com>
20809 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20810 line. This is necessary to allow In_Extended_Main_Unit to provide
20811 correct results for itypes while writing out expanded source.
20812 (Close_File): No need to update the source_index_table here since it's
20813 now done for each line.
20815 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20816 Robert Dewar <dewar@adacore.com>
20818 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20819 preserve the source unit where the itype is declared, and prevent a
20821 (Note_Implicit_Run_Time_Call): New procedure
20822 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
20825 * sprint.ads: Document use of $ for implicit run time routine call
20827 2006-02-13 Quentin Ochem <ochem@adacore.com>
20829 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
20832 2006-02-13 Bob Duff <duff@adacore.com>
20834 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20835 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20836 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20837 raise Constraint_Error.
20839 * s-vallli.adb (Scan_Long_Long_Integer): Call
20840 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20841 do not scan leading blanks and sign twice.
20842 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20843 raise Constraint_Error.
20845 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20846 Scan_Long_Long_Unsigned): Split out most of the processing from
20847 Scan_Long_Long_Unsigned out into
20848 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20849 This prevents scanning leading blanks and sign twice.
20850 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20853 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20854 out most of the processing from Scan_Unsigned out into
20855 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20856 This prevents scanning leading blanks and sign twice.
20858 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20859 use with Modular'Value attribute.
20860 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
20863 2006-02-13 Robert Dewar <dewar@adacore.com>
20865 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
20867 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>

20876 Ben Brosgol <brosgol@adacore.com>
20877 Robert Dewar <dewar@adacore.com>
20879 * gnat_rm.texi, gnat_ugn.texi: Remove limitations with sparc m64
20881 Document that gnatbind -M option is for cross environments only.

21058 * a-taster.ads, a-taster.adb: New files.
21060 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21061 link to the version that does nothing. This way the task termination
21062 routine is not executed twice for the environment task when finishing
21063 because of an unhandled exception.
21065 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21066 handler because of an unhandled exception.
21068 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

21071 * s-finimp.adb (initialization code): Modify the soft link for the
21072 finalization of the global list instead of Adafinal.
21074 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21075 non-tasking version of the soft link for task termination. We do
21076 nothing since if we are using the non-tasking version it
21077 means that the task termination functionality is not used.
21078 (Null_Finalize_Global_List): Add this null version for the procedure
21079 in charge of finalizing the global list for controlled objects.
21080 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21081 instead for handling run-time termination in a more flexible way.
21082 (Adafinal_NT): This new procedure will take care of finalizing the
21083 global list for controlled objects if needed, but no tasking
21086 * s-tarest.adb (Task_Lock): Do not try to lock again the
21087 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21088 some run-time operations.
21089 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21090 until all nested locks have been released.
21091 (Task_Wrapper): Call the fall-back task termination handler. It
21092 applies to all tasks but the environment task.
21093 (Finalize_Global_Tasks): Add the call for the task termination
21094 procedure for the environment task.
21095 (Task_Wrapper): suppress warnings around declaration of
21096 Secondary_Stack_Address.
21098 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21099 moved to the Common_ATCB record.
21100 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21101 Common_ATCB record.
21102 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21103 Common_ATCB record.
21105 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21106 Fall_Back_Handler, and Specific_Handler.
21108 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21109 defined in Ada.Task_Termination, to avoid circular dependencies.
21110 (Termination_Handler): Redefine this type here, alredy defined in
21111 Ada.Task_Termination, for avoiding circular dependencies.
21112 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21113 for storing task termination handlers. In addition,
21114 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21115 Common_ATCB because it is used by both the regular and the restricted
21117 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21118 Common_ATCB because it is used by both the regular and the restricted
21120 (Common_ATCB): Added a dynamic task analyzer field.
21122 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21123 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21124 (Task_Wrapper): Call the task termination handler. It applies to all
21125 tasks but the environment task.
21126 (Finalize_Global_Tasks): Call the task termination procedure for the
21127 environment task. The call to Finalize_Global_List is now performed
21128 using the soft links mechanism.
21129 (Task_Wrapper): added dynamic stack analysis.
21131 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21132 potentially blocking operations has been moved from
21133 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21134 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21135 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21136 this run-time check.
21138 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21139 of task termination procedure.
21140 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21141 link for the task termination procedure.
21143 * bindusg.adb: (Bindusg): Added documentation for -u option.

21157 (Standart_Output): new subprogram
21158 (Set_Output): new subprogram
21159 (Put): now uses the value of Current_Out to know if the output has to be
21160 send to stderr or stdout.
21162 * s-stausa.ads: Complete implementation.
21164 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
21166 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
21167 list of Ada 05 files.
21168 (GNAT Library Units): Add AltiVec files.

21171 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
21172 g-alvety.ads, g-alvevi.ads: New files providing altivec API.
21174 2005-12-09 Nicolas Setton <setton@adacore.com>

21177 file_name is empty.
21179 2005-12-09 Javier Miranda <miranda@adacore.com>
21180 Hristian Kirtchev <kirtchev@adacore.com>
21182 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21183 to the specification because the frontend generates code that uses this
21185 (Set_Interface_Table): Add missing assertion.
21186 Update documentation describing the run-time structure.
21187 (Displace): New subprogram that displaces the pointer to the object
21188 to reference one of its secondary dispatch tables.
21189 (IW_Membership): Modified to use the new table of interfaces.
21190 (Inherit_TSD): Modified to use the new table of interfaces.

21192 contents of the new table of interfaces.
21193 (Set_Interface_Table): New subprogram that stores in the TSD the
21194 pointer to the table of interfaces.

21208 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21209 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21210 record component containing the tag of the secondary dispatch table we
21211 have to use the Offset_To_Top run-time function to get this information;
21212 otherwise if the pointer to the base of the object has been displace
21213 we get a wrong value if we use the 'position attribute.
21215 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21216 all the calls to Expand_Interface_Thunk.
21217 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

21220 ensure that the interfaces implemented by the ancestors are placed
21221 at the header of the generated list.
21222 (Expand_Interface_Conversion): Handle the case in which the displacement
21223 associated with the interface conversion is not statically known. In

21253 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21254 Init_Secondary_Tags_Internal to allow its use with interface types and
21255 also to generate the code for the new additional actual required
21256 by Set_Offset_To_Top.
21257 (Build_Init_Statements): In case of components associated with abstract
21258 interface types there is no need to generate a call to its IP.

21270 properly protected objects and attach handler in the case of the
21271 restricted profile.

21284 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21285 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21286 about the use and expansion of SAVE_EXPRs in the various possible
21287 renaming handling cases.
21288 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21289 abusing DECL_FCONTEXT.

21389 covered by the tag of the source.
21391 2005-12-09 Robert Dewar <dewar@adacore.com>
21393 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean
21394 parameter in call to Image_Wide_Character.

21408 component associated with the secondary table of an abstract interface
21409 type, return the entity associated with such abstract interface type.
21410 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
21411 base type to create anonymous subtype, because entity may be a locally
21412 declared subtype or generic actual.
21413 (Find_Interface): New subprogram that given a tagged type and one of its
21414 component associated with the secondary table of an abstract interface
21415 type, return the entity associated with such abstract interface type.

21418 conversion cannot be handled at compile time. In this case we pass this
21419 information to the expander to generate the appropriate code.

21457 legal within a protected type that implements an interface.
21458 (Collect_Interfaces): Do not add to the list the interfaces that
21459 are implemented by the ancestors.
21460 (Derived_Type_Declaration): If the parent of the full-view is an
21461 interface perform a transformation of the tree to ensure that it has
21462 the same parent than the partial-view. This simplifies the job of the
21463 expander in order to generate the correct object layout, and it is
21464 needed because the list of interfaces of the full-view can be given in
21466 (Process_Full_View): The parent of the full-view does not need to be
21467 a descendant of the parent of the partial view if both parents are
21469 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21470 "limited" the parent must be a limited type.

21484 (Process_Full_View): Improve the check for the "no hidden interface"
21485 rule as defined by AI-396.
21487 2005-12-09 Robert Dewar <dewar@adacore.com>

21544 available user-specified stream attributes on limited parameters to
21545 also test the type directly rather than only its underlying type (for
21546 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21547 attributes are visible at the point of the subprogram declaration.
21548 For Ada 2005, the error message is modified to indicate that the
21549 type's stream attributes must be visible (again, only for -gnat05).

21581 types use the corresponding record type. This was not needed before
21582 the implementation of Ada 2005 synchronized types because
21583 concurrent types were never tagged types in Ada 95.

21716 Roger Sayle <roger@eyesopen.com>
21719 * misc.c (internal_error_function): Don't use vsprintf to format

21731 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
21732 a temporary if taking the address of something that is neither
21733 reference, declaration, or constant, since the gimplifier

21807 TARGET, as it has the form of a math expression, and some components
21808 may be platform-defined macros.
21809 For VxWorks, generate the OK and ERROR values.
21810 New constants giving the sizes of the components of C struct timeval.

21823 checks does not count in the first case, but does in the second).

21829 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
21830 elementary types using the operator in standard. It is cleaner not to
21831 modify the programmers intent, especially in the case of floating-point.
21832 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
21833 it did not matter because we always rewrote a/=b to not(a=b).
21834 (Expand_Allocator_Expression): For an allocator expression whose nominal
21835 subtype is an unconstrained packed type, convert the expression to its
21836 actual constrained subtype.
21837 Implement warning for <= or >= where < or > not possible
21838 Fix to Vax_Float tests (too early in many routines, causing premature
21839 Vax_Float expansions.
21841 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
21842 to be used with packages and generic packages as well as with

21845 of pragma Suppress (All_Checks)
21846 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
21847 a string literal for precise control over warnings.

21857 Allow optional = after -gnatm
21858 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
21859 longer sets Elaboration_Checks.
21860 Code to set warning mode moved to Sem_Warn
21861 so that it can be shared by pragma processing.
21863 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
21866 * s-taprop-solaris.adb:
21867 Change some <= to =, to avoid new warning

21873 2005-11-14 Robert Dewar <dewar@adacore.com>
21875 * exp_vfpt.adb: Handle /= case
21876 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
21877 so that we do not get duplicate scaling for fixed point conversions.
21879 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
21881 2005-11-14 Matthew Gingell <gingell@adacore.com>
21883 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
21884 Increase default priority on Lynx from 15 to 17, and meet the Ada
21885 requirement that Default_Priority be ((Priority'First +
21886 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

21988 we are not defining the type.
21989 <E_Record_Type>: Likewise.
21990 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
21991 to get advantage of the new maybe_stabilize_reference interface, to
21992 ensure that what we reference is indeed stabilized instead of relying
21993 on assumptions on what the stabilizer does.
21994 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
21995 type imported through a limited_with clause, use its non-limited view.
21996 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
21998 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
21999 of #if sections + explicit comparisons of convention identifiers.

22001 before early-returning for certain types when code generation is
22003 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

22005 that we are not defining.
22006 (elaborate_expression_1): Do not create constants when creating
22007 variables needed by the debug info: the dwarf2 writer considers that
22008 CONST_DECLs is used only to represent enumeration constants, and emits
22010 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22011 object with an address clause into an indirect reference, drop the
22012 initializing expression.
22014 (STACK_CHECK_BUILTIN): Delete.

22023 if there is an actual subtype provided by the front-end, use that
22024 subtype to build an actual type with bounds template.
22025 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22026 is provided by the front-end, use that subtype to compute the size of
22027 the deallocated object.
22028 (gnat_to_gnu): When adding a statement into an elaboration procedure,
22029 check for a potential violation of a No_Elaboration_Code restriction.
22030 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22031 with extra arguments to control whether to recurse through non-values

22034 maybe_stabilize, for common uses without restriction on lvalues and
22035 without need to check for the success indication.
22036 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22037 pass false instead of 0 as the FORCE argument which is a bool.
22038 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22039 attached to a renaming pointer has been properly stabilized, as no such
22040 object is attached otherwise.
22041 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22042 function uses the "target pointer" return mechanism.
22043 Reinstate conversion of the actual to the type of the formal
22044 parameter before any other specific treatment based on the passing
22045 mechanism. This turns out to be necessary in order for PLACEHOLDER
22046 substitution to work properly when the latter type is unconstrained.

22050 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

22052 and to let the caller know if the stabilization has succeeded.
22054 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22055 static output of record constructor if all the components are constant.
22056 (gnat_build_constructor): For a record type, sort the list of field
22057 initializers in increasing bit position order.
22058 Factor common code to build a storage type for an unconstrained object
22059 from a fat or thin pointer type and a constrained object type.
22060 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22061 types variants, and process special cases of VIEW_CONVERT expressions
22062 as their NOP_EXPR counterpart to ensure we get to the
22063 CORRESPONDING_VARs associated with CONST_DECls.
22064 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22065 on the right-hand side.

22072 extracting the object if converting to a type variant.
22073 (create_var_decl): When a variable has an initializer requiring code
22074 generation and we are at the top level, check for a potential violation
22075 of a No_Elaboration_Code restriction.
22076 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22077 SIZE and SIZE_UNIT which we need for later back-annotations.

22079 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
22080 is an unchecked union.
22081 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22082 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22083 main variant, just replace the VIEW_CONVERT_EXPR.

22219 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22220 for task component, in the case of a limited aggregate. The enclosed

22222 nested aggregate, the object may appear in the wrong scope.
22223 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
22224 (Gen_Assign): If the component being assigned is an array type and the

22258 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
22259 and related): For a prefix that is an explicit dereference of an

22261 with an actual subtype so GIGI can make a correct size computation.
22262 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22263 'Unrestricted_Access, if the designated type is an interface we
22264 add a type conversion to force the displacement of the pointer

22266 Use Universal_Real instead of Long_Long_Float when we need a high
22267 precision float type for the generated code (prevents gratuitous
22268 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22269 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22270 'Terminated for task interface class-wide objects. Generate a call to
22271 the predefined dispatching routine used to retrieve the _task_id from

22300 (Expand_N_Return_Statement): When returning a mutable record, convert
22301 the return value into its actual subtype in order to help the backend
22302 to return the actual size instead of the maximum. This is another
22303 aftermath of not returning mutable records on the sec-stack anymore.
22305 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
22306 handling of error msg for suspicious reverse range iteration.

22352 attribute of the N_Free_Statement.
22353 Generate itype for classwide designated object in both cases of
22354 user-specified storage pool: specific and class-wide, not only in the
22356 Raise CE when trying to set a not null access type object to null.
22357 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with

22628 view is a transitive derivation of the ancestor of the partial view.
22629 (Process_Full_View): Rename local subprogram Find_Interface_In_
22630 Descendant to Find_Ancestor_Interface to leave the code more clear.
22631 Remove wrong code that avoids the generation of an error message
22632 when the immediate ancestor of the partial view is an interface.
22633 In addition some minor reorganization of the code has been done to
22634 leave it more clear.
22635 (Analyze_Type_Declaration): If type has previous incomplete tagged
22636 partial view, inherit properly its primitive operations.

22650 be included in the interface list.
22651 (Access_Definition): If the designated type is an interface that may
22652 contain tasks, create Master_Id for it before analyzing the expression
22653 of the declaration, which may be an allocator.

22688 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22689 not try to rewrite a renamed stream attribute, because the operations
22690 on the type may not have been generated.

22692 whose default is abstract because the object type itself is abstract.
22693 (Find_Type): If the type is incomplete and appears as the prefix of a
22694 'Class reference, it is tagged, and its list of primitive operations
22695 must be initialized properly.
22696 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22697 private declaration of a parent unit, prior to compiling the private
22698 part of a child unit, find on the scope stack the proper parent entity
22699 on which to link the use clause.

22729 precision float type for the generated code (prevents gratuitous
22730 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22731 (Resolve_Concatenation_Arg): Improve error message when argument is an
22732 ambiguous call to a function that returns an array.
22733 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
22734 there is an implicit operator in the given scope if we are within an
22735 instance: legality check has been performed on the generic.

23459 code generated by the expander.
23460 (Expand_Interface_Conversion): If the actual is an access type then
23461 build an internal function to handle the displacement. If the actual
23462 is null this function returns null because no displacement is
23463 required; otherwise performs a type conversion that will be
23464 expanded in the code that returns the value of the displaced actual.
23465 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
23466 conversions that have no effect in the generated code because no

23730 whether a potential circularity is harmless, because it includes units
23731 loaded through a limited_with clause. Extends previous treatment which
23732 did not handle properly arbitrary combinations of limited and
23733 non-limited clauses.
23735 2005-09-01 Nicolas Setton <setton@adacore.com>
23737 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
23738 to be encoded as typ___XBLU_lowerbound__upperbound instead of
23739 typ___XB_lowerbound__upperbound.
23741 2005-09-01 Thomas Quinot <quinot@adacore.com>
23743 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
23744 dummy access formal for RACW/RAS TypeCode TSS.
23745 (Build_TypeCode_Call): Do not generate dummy null access actual for
23746 calls to the TypeCode TSS.
23748 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23750 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
23751 fully qualified name, to distinguish instances with the same local name.
23753 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
23756 2005-09-01 Robert Dewar <dewar@adacore.com>

23761 2005-09-01 Jerome Lambourg <lambourg@adacore.com>
23763 * g-expect.adb (Non_Blocking_Spawn): Initialize the filters field to
23764 (Free): New deallocation procedure for filter elements
23765 (Close): Deallocate any existing filter for the concerned connection
23767 2005-09-01 Laurent Pautet <pautet@adacore.com>
23769 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
23770 position set is provided, we compute one in order to reduce the maximum
23771 length of the keys. This computation first selects a character
23772 position between 1 and the minimum length of the keys in order to
23773 avoid reducing one of the keys to an empty string.
23774 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23775 does not converge. The initialization procedure now comes with a
23776 maximum number of iterations such that when exceeded, an exception is
23777 raised in Compute. The user can initialize this ratio to another value
23779 Reformating and updated headers.
23781 2005-09-01 Javier Miranda <miranda@adacore.com>
23783 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
23784 that given an entity T creates and returns an Itype that duplicates the
23785 contents of T. The returned Itype has the null-exclusion
23786 attribute set to True, and its Etype attribute references T
23787 to keep the association between the two entities.
23788 Update copyright notice
23790 * sem_aggr.adb (Check_Can_Never_Be_Null,
23791 Aggregate_Constraint_Checks, Resolve_Aggregate,
23792 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
23794 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

23797 Robert Dewar <dewar@adacore.com>
23798 Hristian Kirtchev <kirtchev@adacore.com>
23800 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
23803 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
23805 Call Set_Result_Definition instead of Set_Subtype_Mark.
23806 (P_Subprogram_Specification): Add parsing of anonymous access result
23807 plus null exclusions. Call Set_Result_Definition instead of
23810 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23811 (P_Access_Type_Definition): Add parsing for an anonymous access result
23812 subtype, plus parsing for null exclusions. Call Set_Result_Definition
23813 instead of Set_Subtype_Mark.
23815 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23816 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
23817 (Result_Definition): New function for N_Function_Specifications.
23818 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
23819 N_Function_Specification.
23820 (Set_Null_Exclusion_Present): Allow this flag for
23821 N_Function_Specification.
23822 (Set_Result_Definition): New procedure for N_Function_Specifications.
23823 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
23824 and N_Function_Specification.
23826 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
23827 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
23828 Add support for LIMITED NEW for Ada 2005 AI-419
23829 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
23830 syntax for anonymous access results.
23831 Replace Subtype_Mark field by Result_Definition in
23832 N_Function_Specification and N_Access_Definition specs.
23833 Add Null_Exclusion_Present to spec of N_Function_Specification.
23834 (Result_Definition): New function for N_Function_Specification and
23835 N_Access_Function_Definition.
23836 (Set_Result_Definition): New procedure for N_Function_Specification and
23837 N_Access_Function_Definition.
23839 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
23840 Result_Definition for cases of N_Access_Function_Definition and
23841 N_Function_Specification.
23842 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
23844 2005-09-01 Vincent Celier <celier@adacore.com>
23846 * lib-writ.adb: Update Copyright notice
23847 (Write_With_Lines): On platforms where file names are case-insensitive,
23848 record the file names in lower case.
23849 (Write_ALI): For D lines, on platforms where file names are
23850 case-insensitive, record the file names in lower case.
23852 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23853 Emmanuel Briot <briot@adacore.com>
23855 * lib-xref.adb (Output_Overridden_Op): Display information on
23856 overridden operation.
23858 * lib-xref.ads: Add documentation on overridden operations.
23860 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
23863 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
23864 overriding entity information.
23866 2005-09-01 Vincent Celier <celier@adacore.com>
23868 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
23869 including those that are inherited.
23871 2005-09-01 Robert Dewar <dewar@adacore.com>
23873 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
23875 * par-prag.adb: Implement new pragma Debug_Policy
23877 * sem_prag.adb Implement new pragma Debug_Policy
23878 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23879 Component_Size attribute specification. Give warning for ignored pragma
23882 * snames.h, snames.ads, snames.adb: Introduce entries in
23883 Preset_Names for Name_Disp_Asynchronous_Select,
23884 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23885 Name_Disp_Timed_Select.
23886 New pragma Debug_Policy
23888 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23890 Switch -gnata also sets Debug_Pragmas_Enabled
23892 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23893 handle an explicit -gnata when compiling predefined files.
23895 2005-09-01 Vincent Celier <celier@adacore.com>
23897 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23898 directories of projects that have no Ada sources.
23900 2005-09-01 Robert Dewar <dewar@adacore.com>
23902 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23903 (makes a difference for wide characters)
23905 * widechar.adb, widechar.ads:
23906 Add Wide_Char_Byte_Count feature to count chars vs bytes
23908 2005-09-01 Thomas Quinot <quinot@adacore.com>
23909 Ed Schonberg <schonberg@adacore.com>
23910 Robert Dewar <dewar@adacore.com>
23912 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23913 'Address attribute reference with an overloaded prefix, use the
23914 location of the prefix (not the location of the attribute reference) as
23915 the error location.
23916 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23917 a function renaming thereof, is a valid prefix for 'Size (where it is
23918 intepreted as a function call).
23919 (Statically_Denotes_Entity): New predicate to determine whether the
23920 prefix of an array attribute can be considered static.
23923 (Eval_Attr): Fix failure to evaluate Component_Size for
23924 unconstrained arrays (resulted in wrong value in packed case, since
23925 back end cannot handle this case)
23927 2005-09-01 Robert Dewar <dewar@adacore.com>
23929 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23930 error msgs for most common cases.
23931 Use new errout insertion char < (conditional warning)
23933 2005-09-01 Javier Miranda <miranda@adacore.com>
23934 Ed Schonberg <schonberg@adacore.com>
23936 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23937 become local to the whole package.
23938 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23939 the package was already analyzed the new algorithm "replaces" the
23940 real entities by the shadow ones. This is required to ensure that
23941 the order of these entities in the homonym chains does not change;
23942 otherwise we can have undefined references at linking time because
23943 in case of conflicts the external name of the entities will have
23944 a suffix that depends on the order of the entities in the chain.
23945 (Remove_Limited_With_Clause): Complementary code that completes the
23946 new algorithm and replaces the shadow entities by the real ones.
23947 (Install_Limited_Withed_Unit): When unchaining entities before the
23948 installation of the shadow entities, only regular entities of the
23949 public part must be taken into account. This is required to
23950 keep this routine in synch with the work done by Remove_Limited_
23952 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
23953 even if unit is analyzed, because the analysis of the unit is
23954 idempotent in any case, and the limited view of the unit may have to
23955 be installed for proper visibility.
23956 (Expand_Limited_With_Clause): Even if the unit in the implicit
23957 with_clause has been analyzed already, a limited view of the package
23958 must be built for the current context, if it does not exist yet.
23960 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23961 Javier Miranda <miranda@adacore.com>
23962 Gary Dismukes <dismukes@adacore.com>
23964 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
23965 defining entity for the instance body, make a new defining identifier
23966 rather than copying the entity of the spec, to prevent accidental
23967 sharing of the entity list.
23968 (Check_Private_View): When exchanging views of private types, build the
23969 list of exchanged views as a stack, to ensure that on exit the exchanges
23970 are undone in the proper order.
23971 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
23972 Restore the compilation environment in case of instantiation_error.
23973 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
23974 for an anonymous access result.
23975 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
23976 (Formal_Entity): Handle properly the case of a formal package that
23977 denotes a generic package renaming.
23979 2005-09-01 Thomas Quinot <quinot@adacore.com>
23981 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
23982 clause if the array aggregate is surrounded by parentheses.
23984 2005-09-01 Cyrille Comar <comar@adacore.com>
23985 Gary Dismukes <dismukes@adacore.com>
23986 Ed Schonberg <schonberg@adacore.com>
23987 Javier Miranda <miranda@adacore.com>
23989 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
23991 to check if a type is Constrained in cases related to code generation
23992 (rather than semantic checking) since otherwise we do not generate
23993 similar code for mutable private types depending if their
23994 discriminants are visible or not.
23995 (Check_Abstract_Overriding): Do not complain about failure to override
23996 the primitive operations used in dispatching selects since they will
23997 always be overriden at the freeze point of the type.
23998 (Access_Definition): Separate out handling for resetting the scope
23999 of an anonymous access function result type. Retrieve the scope
24000 of the associated function rather than using Current_Scope, which
24001 does not have a consistent value (depends on whether we're in the
24002 middle of analyzing formal parameters). Add ??? comment about
24003 finding a cleaner way to handle the special cases of scope setting.
24004 (Process_Incomplete_Dependents): A protected operation is never a
24005 dispatching operation (only its wrapper may be).
24006 (Build_Derived_Record_Type): In case of tagged private types that
24007 implement interfaces add derivation of predefined primitive
24009 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24010 by two parameters that are used in case of derivation from abstract
24011 interface types: No_Predefined_Prims is used to avoid the derivation
24012 of predefined primitives from the interface, and Predefined
24013 Prims_Only is used to complete the derivation predefined primitives
24014 in case of private tagged types implementing interfaces.
24015 Fix typo in comments
24016 (Find_Interface_In_Descendant): Protect the frontend against
24017 wrong code with large circularity chains.
24018 (Is_Private_Overriding): Add support for entities overriding interface
24019 subprograms. The test failed because Entities associated with overriden
24020 interface subprograms are always marked as hidden (and used to build
24021 the secondary dispatch table); in this case the overriden entity is
24022 available through the field abstract_interface_alias (cf. override_
24023 dispatching_operation)
24024 (Access_Definition): Set the scope of the type to Current_Scope for the
24025 case of a function with an anonymous access result type.
24026 (Access_Subprogram_Declaration): Handle creation of the type entity for
24027 an access-to-function type with an anonymous access result.
24028 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24029 in handling for N_Access_Function_Definition.
24030 (Analyze_Subtype_Declaration): Modify the text of error message.
24031 (Derived_Type_Declaration): Modify the text of error message.
24032 (Process_Subtype): Modify the text of error message plus cleanup
24033 of one redundant error message.
24034 (Analyze_Component_Declaration): Code cleanup.
24035 (Analyze_Object_Declaration): Code cleanup.
24036 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24037 attribute in case of access types. Code cleanup.
24038 (Array_Type_Declaration): Code cleanup.
24039 (Process_Discriminants): Create the new null-excluding itype
24040 if required. Code cleanup.
24041 (Process_Subtype): Create the new null-excluding itype if
24042 required. Code cleanup.
24043 (Build_Derived_Record_Type): Code cleanup to avoid calling
24044 twice the subprogram derive_subprograms in case of private
24045 types that implement interfaces. In this particular case the
24046 subprogram Complete_Subprograms_Derivation already does the
24047 job associated with the second call.
24049 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24050 conversion to the full view when generating an operation for a
24051 discriminant whose type may currently be private.
24053 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24054 Javier Miranda <miranda@adacore.com>
24056 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24057 V (Obj.F), the rewriting does not involve the indexed component, but
24058 only the selected component itself.
24059 Do not apply the transformation if the analyzed node is an actual of a
24060 call to another subprogram.
24061 (Complete_Object_Operation): Retain the entity of the
24062 dispatching operation in the selector of the rewritten node. The
24063 entity will be used in the expansion of dispatching selects.
24064 (Analyze_One_Call): Improve location of the error message associated
24066 (Analyze_Selected_Component): No need to resolve prefix when it is a
24067 function call, resolution is done when parent node is resolved, as
24069 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24070 when attempting to resolve a call transformed from its object notation.
24071 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24072 of the argument list for each interpretation of the operation.
24073 (Try_Object_Operation): The designated type of an access parameter may
24074 be an incomplete type obtained through a limited_with clause, in which
24075 case the primitive operations of the type are retrieved from its full
24077 (Analyze_Call): If this is an indirect call, and the return type of the
24078 access_to_subprogram is incomplete, use its full view if available.
24080 2005-09-01 Javier Miranda <miranda@adacore.com>
24081 Gary Dismukes <dismukes@adacore.com>
24083 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24084 access types the null-exclusion and access-to-constant attributes must
24086 (Analyze_Return_Statement): When the result type is an anonymous access
24087 type, apply a conversion of the return expression to the access type
24088 to ensure that appropriate accessibility checks are performed.
24089 (Analyze_Return_Type): For the case of an anonymous access result type,
24090 generate the Itype and set Is_Local_Anonymous_Access on the type.
24091 Add ??? placeholder for check to disallow returning a limited object
24092 in Ada 2005 unless it's an aggregate or a result of a function call.
24093 Change calls from Subtype_Mark to Result_Definition.
24094 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24095 Result_Definition in call to Make_Function_Specification.
24096 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24097 Set_Result_Definition.
24098 (Make_Inequality_Operator): Change formal Subtype_Mark to
24099 Result_Definition in call to Make_Function_Specification.
24100 (Process_Formals): Create the new null-excluding itype if required.
24101 (New_Overloaded_Entity): For an entity overriding an interface primitive
24102 check if the entity also covers other abstract subprograms in the same
24103 scope. This is required to handle the general case, that is, overriding
24104 other interface primitives and overriding abstract subprograms inherited
24105 from some abstract ancestor type.
24106 (New_Overloaded_Entity): For an overriding entity that comes from
24107 source, note the operation that it overrides.
24108 (Check_Conformance, Type_Conformant): Addition of one new formal
24109 to skip controlling formals in the analysis. This is used to
24110 handle overloading of abstract interfaces.
24111 (Base_Types_Match): Add missing case for types imported from
24112 limited-with clauses
24113 (New_Overloaded_Entity): Add barrier to protect the use of
24114 the "alias" attribute.
24116 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24118 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24119 verify that the procedure and the entry are mode conformant.
24120 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24121 as a different operator, which is often a cut-and-paste error.
24123 2005-09-01 Javier Miranda <miranda@adacore.com>
24124 Ed Schonberg <schonberg@adacore.com>
24126 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24127 used in controlling parameters exclude null because it is necessary to
24128 read the tag to dispatch, and null has no tag.
24129 (Override_Dispatching_Operation): If the previous operation is inherited
24130 from an interface, it becomes hidden and does not participate in later
24133 2005-09-01 Javier Miranda <miranda@adacore.com>
24134 Ed Schonberg <schonberg@adacore.com>
24135 Gary Dismukes <dismukes@adacore.com>
24137 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24138 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24139 the expander will generate the corresponding run-time check to evaluate
24141 (Resolve_Call): Check for legal type of procedure name or prefix that
24142 appears as a trigger in a triggering alternative.
24143 (Valid_Conversion): If expression is ambiguous and the context involves
24144 an extension of System, remove System.Address interpretations.
24145 (Resolve_Qualified_Expression): Reject the case of a specific-type
24146 qualification applied to a class-wide argument. Enhance comment
24147 to explain checking of Original_Node.
24148 (Resolve_Type_Conversion): The location of the error message was not
24149 general enough to handle the general case and hence it has been removed.
24150 In addition, this patch improves the text of the message.
24151 (Resolve_Type_Conversion): Add missing support for access to interface
24153 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24154 do not expand if the expression is the actual in a call, because proper
24155 expansion will take place when the call itself is expanded.
24156 (Resolve_Allocator): If the context is an unchecked conversion, the
24157 allocator inherits its storage pool, if any, from the target type of
24160 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24161 Javier Miranda <miranda@adacore.com>
24163 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24164 inherited interface operation that has an implementation, use the
24165 implementation to avoid spurious ambiguities.
24166 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24167 use the Corresponding_Record_Typ attribute to look for the interface
24168 because it is set by the expander (and hence it is not always
24169 available). For this reason we traverse the list of interfaces
24170 (available in the parent of the concurrent type).
24171 (Interface_Present_In_Ancestor): Handle entities from the limited view
24173 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24175 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24176 from the list of required components.
24177 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24178 primitive procedure of a limited interface with a controlling first
24180 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24182 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24183 capture if it is generated in the second operand of a short-circuit
24185 Do not capture values for variables with address clauses.
24186 (Is_Object_Reference): Treat a function call as an object reference only
24187 if its type is not Standard_Void_Type.
24189 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24191 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24192 to a variable that is statically known to be constant.
24194 2005-09-01 Geert Bosch <bosch@adacore.com>
24195 Robert Dewar <dewar@adacore.com>
24197 * ttypef.ads (VAXDF_Safe_First): Use correct value for constant.
24198 (VAXGF_Safe_First): Idem.
24200 2005-09-01 Robert Dewar <dewar@adacore.com>

25418 error message condition, null procedures are correctly detected now.
25419 (New_Overloaded_Entity): Bypass trivial overriding indicator check

25424 on subprogram stubs as well.
25425 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
25427 (Analize_Subprogram_Specification): When analyzing a subprogram in which

25429 by the corresponding record type.
25430 (Analyze_Subprogram_Body): Undo the previous work.
25431 (Analyze_Procedure_Call): If the call has the form Object.Op, the

25440 access to subprograms must be recursive.
25441 (Is_Unchecked_Conversion): Improve the test that recognizes
25442 instantiations of Unchecked_Conversion, and allows them in bodies that
25443 are to be inlined by the front-end. When the body comes from an
25444 instantiation, a reference to Unchecked_Conversion will be an
25445 Expanded_Name, even though the body has not been analyzed yet.

25464 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
25465 in the case where the target type is an anonymous access type of an
25466 object or component (that is, when Is_Local_Anonymous_Access is true).
25467 Prevent the special checks for conversions of access discriminants in
25468 the case where the discriminant belongs to a nonlimited type, since
25469 such discriminants have their accessibility level defined in the same
25470 way as a normal component of an anonymous access type.
25471 (Resolve_Allocator): When an allocator's designated type is a class-wide
25472 type, check that the accessibility level of type given in the
25473 allocator's expression or subtype indication is not statically deeper
25474 than the level of the allocator's access type.

25485 (Resolve_Actuals): Enable full error reporting on view conversions
25486 between unrelated by_reference array types.
25487 The rule for view conversions of arrays with aliased components is
25488 weakened in Ada 2005.
25489 Call to obsolescent subprogram is now considered to be a violation of
25490 pragma Restrictions (No_Obsolescent_Features).
25491 (Check_Direct_Boolean_Operator): If the boolean operation has been
25492 constant-folded, there is nothing to check.
25493 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25494 check on possible violation of restriction No_Direct_Boolean_Operators
25495 until after expansion of operands, to prevent spurious errors when

25530 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
25531 both bound checks, rather than a conjunction.
25532 (Insert_Valid_Check): If the expression is an actual that is an indexed
25533 component of a bit-packed array, force expansion of the packed element
25534 reference, because it is specifically inhibited elsewhere.

25918 (Get_Type_Reference): For a subtype that is the renaming of an actual in
25919 an instantiation, use the first_subtype to ensure that we don't generate

26500 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26501 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26502 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26503 analyzed if expansion is disabled (which could otherwise cause spurious
26504 error messages if expansion has been disabled due to previous
26505 (unrelated) errors).
26507 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26508 is disabled, the entity denoted by the argument is the access type
26509 itself, not an underlying record type, so there is no need to go back
26510 to the Corresponding_Remote_Type.
26512 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26513 Robert Dewar <dewar@adacore.com>
26515 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
26516 expand a call to an instance of
26517 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the

26519 check is also generated, to ensure that the tag passed to the instance
26520 denotes a type in the class.
26521 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26522 of Name_Generic_Dispatching_Constructor.
26524 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26525 05 unit for AI-260-02).

26540 generic formal subprogram association for an abstract formal subprogram.
26541 Check that the attribute is a primitive stream attribute (and not
26542 a class-wide stream attribute) and then rewrite the attribute name
26543 as the name of the appropriate compiler-generated stream primitive.
26545 2005-03-29 Robert Dewar <dewar@adacore.com>
26547 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

26555 itype whose parent is controlled and not yet frozen, do not create a
26556 freeze node for the itype if expansion is disabled.
26558 2005-03-29 Vincent Celier <celier@adacore.com>
26560 * make.adb (Gnatmake): Don't fail if the main project file is declared
26561 as having no Ada sources. Do not display message "no sources to
26562 compile" in quiet output.
26564 2005-03-29 Doug Rupp <rupp@adacore.com>
26566 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26582 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26583 rather than proceed ahead using a junk attribute name.
26585 2005-03-29 Vincent Celier <celier@adacore.com>
26587 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26589 * prj-part.adb (Parse_Single_Project): Set the location of a project
26590 on its defining identifier, rather than on the reserved word "project".
26592 * prj-proc.adb (Expression): Adapt to the fact that default of external
26593 references may be string expressions, not always literal strings.
26594 (Recursive_Process): Set Display_Name equal to Name
26595 when Location is No_Location, that is when there is no actual file.
26596 Get the Display_Name of the project from the source, when it is not a
26598 (Process): Use the Display_Name in error messages
26600 * prj-strt.adb (External_Reference): Allow default to be string
26601 expressions, not only literal strings.
26603 2005-03-29 Vincent Celier <celier@adacore.com>

26610 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
26611 forbid conversion of a local access-to-subprogram type to a remote one.
26613 * sem_util.adb (Wrong_Type): For a record type that is the expanded
26614 equivalent type for a remote access-to-subprogram type, go back to the
26615 original RAS entity when displaying an error message, so the casing is
26616 the original source casing.

26620 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
26623 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26625 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26626 subtype if code is being pre-analyzed, to prevent un-expanded
26627 references to protected formals, among others.
26628 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26629 interpretation that can be a call, include the result of the call as a
26630 possible interpretation of the dereference.
26632 * sem_ch5.adb (Process_Bounds): Determine type of range by
26633 pre-analyzing a copy of the original range, and then analyze the range
26634 with the expected type.
26636 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26637 with an overloaded prefix where not all interpretations yield an
26638 access to subprogram, do not rewrite node as a call.
26639 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26640 the node as a call once the context identifies the interpretation of
26641 the prefix whose call yields the context type.
26642 (Valid_Conversion): For the case of a conversion between
26643 local access-to-subprogram types, check subtype conformance using
26644 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26645 detailed error message.

26649 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26650 indicator, indicate that the formal can never be null.
26651 (Process_Formals): If a formal has a non_null indicator, insert the
26652 resulting subtype immediately before the enclosing subprogram decl,
26653 and not at the beginning of the corresponding declarative part, to
26654 prevent access before elaboration (Ada2005).

26763 to install the visible declarations of the enclosing scope of a
26764 record_type_with_private to establish the proper visibility before
26765 freezing the entity and related subprograms.

26776 into a new Check_Attr subprogram, in order to provide a more
26777 explanatory error message (including the name of the missing attribute).
26778 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
26779 subprogram determines whether a default implementation exists for a
26780 given stream attribute.
26781 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
26782 Determine whether to generate a default implementation for each stream
26783 attribute separately, as this depends on the specific attribute.
26785 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
26786 limited extension where a stream attribute is missing for a limited
26787 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

27320 These subprogram have been removed because the attribute
27321 Task_Body_Procedure has been moved to the corresponding task type
27322 or task subtype entity to leave a field free to store the list
27323 of interfaces implemented by a task (for AI-345)
27324 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27325 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27326 expression flag Do_Range_Check
27327 (Exception_Junk): Change to Flag7 to accomodate above change
27328 (Box_Present, Default_Name, Specification, Set_Box_Present,
27329 Set_Default_Name, Set_Specification): Expand the expression
27330 "X in N_Formal_Subprogram_Declaration" into the corresponding
27331 two comparisons. Required to use the csinfo tool.
27333 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
27334 "with string" given.
27336 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
27339 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
27342 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27343 attribute Task_Body_Procedure rather than the old semantic field that
27344 was available in the task_type_declaration node.
27346 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27347 interface type definitions.
27348 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27351 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
27352 task type declaration.
27353 (P_Protected): Modified to handle the list of interfaces in a
27354 protected type declaration.
27356 2005-03-15 Doug Rupp <rupp@adacore.com>
27357 Vincent Celier <celier@adacore.com>
27359 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27360 (Gen_Output_File_C): Likewise.
27361 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
27363 2005-03-15 Thomas Quinot <quinot@adacore.com>
27365 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27366 is an N_Raise_Constraint_Error node, create a new copy of it without
27367 going through a call to Duplicate_Subexpr.
27369 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
27370 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27371 Nicolas Setton <setton@adacore.com>
27372 Ed Schonberg <schonberg@adacore.com>
27378 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27379 representation clause that prescribes a size not equal to the rounded
27380 size of their types.
27381 (gnat_to_gnu_entity, case E_Component): Always look at
27382 Original_Record_Component if Present and not the entity.
27383 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27384 of tagged extension types by not making field for components that are
27386 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27387 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27388 expression to the type of the object when the object is constant.
27389 Reverse defer_debug_incomplete_list before traversing it, so that trees
27390 are processed in the order at which they were added to the list. This
27391 order is important when using the stabs debug format.
27392 If we are deferring the output of debug information, also defer this
27393 output for a function return type.
27394 When adding fields to a record, prevent emitting debug information
27395 for incomplete records, emit the information only when the record is
27397 (components_to_record): New parameter defer_debug.
27398 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27399 (gnat_to_gnu_field_decl): New function.
27400 (substitution_list, annotate_rep): Call it.
27401 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27402 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27403 No longer update discriminants to not be a COMPONENT_REF.
27404 (copy_alias_set): Strip padding from input type; also handle
27405 unconstrained arrays properly.
27407 * gigi.h (write_record_type_debug_info): New function.
27408 Convert to use ANSI-style prototypes. Remove unused
27409 declarations for emit_stack_check, elab_all_gnat and
27410 set_second_error_entity.
27411 (gnat_to_gnu_field_decl): New decl.
27413 * utils.c (write_record_type_debug_info): New function.

27416 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27417 (update_pointer_to): Fix pasto.
27418 (convert) <UNION_TYPE>: Accept slight type variations when
27419 converting to an unchecked union type.
27421 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27422 replace the N_Freeze_Entity with a null statement.
27424 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27425 within a constrained subcomponent of an enclosing record, place the
27426 freeze nodes in the scope stack entry for the enclosing record.
27427 (Undelay_Type): New Subprogram.
27428 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27429 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27430 within records; allow them to have freeze nodes if their base types
27433 * exp_util.adb (Remove_Side_Effects): Properly test for
27434 Expansion_Delayed and handle case when it's inside an
27435 N_Qualified_Expression.
27437 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27438 Comes_From_Generic, to recognize accurately that the parent type in a
27439 derived type declaration can be traced back to a formal type, because
27440 it is one or is derived from one, or because its completion is derived
27442 (Constrain_Component_Type): If component comes from source and has no
27443 explicit constraint, no need to constrain in in a subtype of the
27445 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27446 Minor change to propagate Is_Ada_2005 flag
27448 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27449 Expansion_Delayed is False.
27450 (assoc_to_constructor): Ignore fields that have a
27451 Corresponding_Discriminant.
27452 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27453 function returns "by target", dereference the target pointer using the
27454 type of the actual return value.
27455 <all>: Be prepared for a null gnu_result.
27456 (processed_inline_subprograms): Check flag_really_no_inline
27457 instead of flag_no_inline.
27458 (set_second_error_entity): Remove unused function.

27463 2005-03-15 Robert Dewar <dewar@adacore.com>
27464 Ed Schonberg <schonberg@adacore.com>
27465 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27467 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27468 Must_Be_Byte_Aligned for cases where we do not need to use a
27469 System.Pack_nn unit.
27471 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27473 Needed now that we do some processing for IN parameters as well. This
27474 may well fix some unrelated errors.
27475 (Expand_Call): Handle case of unaligned objects (in particular those
27476 that come from packed arrays).
27477 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27478 renamed entity is an inherited operation, re-expand the call using the
27479 original operation, which is the one to call.
27480 Detect attempt to inline parameterless recursive subprogram.
27481 (Represented_As_Scalar): Fix to work properly with private types
27482 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27483 accurate estimate. Yields True in far fewer cases than before,
27484 improving the quality of code that depends on this test.
27486 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27487 over both visible and private declarations to remove them from tree,
27488 and mark subprograms declared in package as eliminated, to prevent
27489 spurious use in subsequent compilation of generic units in the context.
27491 * exp_util.ads: Minor cleanup in variable names
27493 * sem_eval.ads, sem_eval.adb: Minor reformatting
27494 (Compile_Time_Known_Bounds): New function
27496 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27498 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27499 determining whether an unchecked conversion is needed for the argument
27500 of an initialization call.
27502 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27504 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27505 that appears in the instantiation rather than the internal subtype
27506 generated in the wrapper package, to avoid anomalies in gigi when the
27507 target is derived from a private type whose full view is an access type.
27509 2005-03-15 Robert Dewar <dewar@adacore.com>
27511 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27513 Add documentation to replace the use of this flag
27514 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27517 2005-03-15 Thomas Quinot <quinot@adacore.com>
27519 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27520 here from exp_attr so it can be shared between exp_attr and exp_dist.
27521 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27522 all TSS names, not a subset thereof, and the previous name introduced
27523 an unnecessarily confusion that a distinction might exist between
27524 "OK" TSS names and some "not OK" TSS names.
27526 2005-03-15 Doug Rupp <rupp@adacore.com>
27528 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27531 2005-03-15 Pascal Obry <obry@adacore.com>
27532 Eric Botcazou <ebotcazou@adacore.com>
27536 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27537 when IN_RTS. This is to work around a bootstrap path problem.
27539 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27540 table and pass it to __gnat_install_SEH_handler().
27541 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27543 * lang.opt: Fix specification of -fRTS=.
27545 2005-03-15 Doug Rupp <rupp@adacore.com>

27547 Vincent Celier <celier@adacore.com>
27548 Arnaud Charlet <charlet@adacore.com>
27551 This change works fine when gnatlib is built from the gcc directory,
27552 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27553 is not passed to ada/Makefile.in, so more work is needed by a
27554 Makefile/configure expert.
27556 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27557 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27558 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27560 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27561 Run ranlib on libgccprefix.a
27562 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27563 (ADA_INCLUDE_SRCS): Split Ada packages.
27565 2005-03-15 Robert Dewar <dewar@adacore.com>
27567 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27569 * impunit.adb: Add GNAT.UTF_32
27571 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27573 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27574 now uses GNAT.UTF_32).
27576 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27577 capabilities for categorizing characters using Unicode categories
27579 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27581 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27582 instantiation that has been rewritten as a package body, retrieve spec
27583 to generate proper name for implicit_with_clause.
27584 (Install_Parents): Recognize a parent that is an instantiation but has
27585 been rewritten as a package declaration during analysis.
27587 2005-03-15 Javier Miranda <miranda@adacore.com>
27588 Ed Schonberg <schonberg@adacore.com>
27590 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27591 parameter reported some error we immediately return. This improves the
27592 behaviour of the frontend in case of errors.
27593 (Install_Parent, Remove_Parent): Introduce new flag
27594 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27595 ancestor of a generic child unit, when the child is being instantiated.
27596 (Inline_Instance_Body): If we are compiling the private
27597 part or the body of a child unit, restore the proper visibility of the
27598 parents after compiling the instance body.
27600 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27601 Javier Miranda <miranda@adacore.com>
27604 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27605 of a private type, in which case it is underlying_type that denotes
27606 the proper task. Also modified to use the new entity attribute
27607 that is directly available in the task type and task subtype entities
27608 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27609 arrays when other dimensions than the first are constrained by
27610 discriminants of an enclosing record.
27611 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27612 a combination of indexed and selected components, find ultimate entity
27613 and generate the appropriate reference for it, to suppress spurious
27615 (Note_Possible_Modification): If an entity name has no entity, return.
27616 (Is_Variable): A function call never denotes a variable.
27617 (Requires_Transient_Scope): For record types, recurse only on
27618 components, not on internal subtypes that may have been generated for
27619 constrained components.
27621 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27623 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27624 Eliminated as candidates for resolution. Both efficient, and avoids
27625 anomalies with operators declared in deleted code.
27626 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27627 expansion is disabled (as when compiling a generic) to prevent spurious
27628 warnings on prefixes of selected components.
27630 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27632 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27633 attached to a list before checking whether it appears in the private
27634 declarations of the current package.
27635 (Make_Inequality_Operator): Insert declaration in proper declarative
27636 list rather than just setting the Parent field, so that
27637 Is_Private_Declaration can handle it properly.
27639 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27641 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27642 a renaming a body, check that the renamed subprogram in not intrinsic.
27643 (Find_Direct_Name): If several use_visible entities hide
27644 each other, and the context is a predefined file compiled through
27645 rtsfind, keep only the entity that comes from a predefined file.
27647 2005-03-15 Geert Bosch <bosch@adacore.com>
27649 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27650 long float padding to also cover AMD64 and IA64.
27652 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27654 * s-imgwch.adb: Add with and use of Interfaces.
27655 (Img_Wide_Character): Change type of Val to Unsigned_16.
27656 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27658 2005-03-15 Matthew Gingell <gingell@adacore.com>
27660 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
27662 2005-03-15 Robert Dewar <dewar@adacore.com>

27666 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
27668 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
27670 2005-03-15 Robert Dewar <dewar@adacore.com>

27694 procedures in the bug boxes for various GNAT builds.
27696 2005-03-15 Vincent Celier <celier@adacore.com>
27698 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

27703 Cyrille Comar <comar@adacore.com>
27704 Sergey Rybin <rybin@adacore.com>
27706 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
27707 too specific and long-winded to be appropriate for the GNAT User's
27709 Warn about use of GCC switches not documented in the GNAT User's Guide,
27710 as these may cause generated code to not conform to Ada semantics.
27711 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
27712 Add documentation for -gnat95 and -gnat05 switches
27713 Remove paragraph documenting obsolete way to refer to third party
27715 Add a few references to Ada_05 that were missing.
27716 Update documentation on -gnatZ/-gnatL.
27717 Document limitation when using -m64 under Solaris.

27761 we asked for an unknown mode.
27763 2005-02-12 Richard Henderson <rth@redhat.com>
27765 * utils.c (gnat_type_for_mode): Return NULL for COMPLEX modes;

28132 the formal subprogram.
28133 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28134 which is an unclean use of that field, we set the new field

28158 as the tagged type for the cases of abstract formal subprograms and
28159 renamings of those. Clean up spec comments.

28161 procedure", covering the case of a call to a formal abstract procedure
28162 that has statically tagged operands.

28164 a tag-indeterminate function call whose type is an ancestor of the
28165 containing call's associated tagged type. This situation can occur

28280 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28281 unchecked union with no inferable discriminants, return a
28282 Raise_Program_Error node, rather than inserting it at the point the
28284 (Expand_Record_Equality, Component_Equality): Handle properly the case
28285 where some subcomponent is an unchecked union whose generated equality
28286 code raises program error.
28288 2005-02-09 Doug Rupp <rupp@adacore.com>
28290 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.
28291 [VMS] (#define exit hack): Remove.
28293 2005-02-09 Pascal Obry <obry@adacore.com>
28294 Arnaud Charlet <charlet@adacore.com>
28296 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28297 address of the exception registration. The Win32 version of this
28298 routine calls __gnat_install_SEH_handler() to initialize the SEH
28299 (Structured Exception Handling) handler.
28300 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28301 SEH (Structured Exception Handling) now.
28302 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28303 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28304 preprocessor condition protecting the call to the extra eh setup
28305 subprogram, which is only available for the ppc target.
28306 (__gnat_clear_exception_count): replaced reference to
28307 variable taskIdCurrent by call to taskIdSelf(), cleaner.
28309 * seh_init.c: New file.
28311 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
28312 (GNATBIND_OBJS): Idem.
28314 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28315 routine takes a new parameter (a pointer to the exception registration
28316 for the SEH (Structured Exception Handling) support.
28318 * raise.h: (__gnat_install_SEH_handler): New prototype.
28319 Update copyright notice.
28321 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28322 record and initialize it by calling __gnat_install_SEH_handler.
28324 2005-02-09 Vincent Celier <celier@adacore.com>
28326 * make.adb (Gnatmake): Do not fail when the main project has no object

28332 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
28333 [VMS]: Add translations for g-enblsp.adb.
28335 * s-asthan-vms.adb: Removed.
28336 * s-asthan-vms-alpha.adb: Added.
28338 2005-02-09 Pascal Obry <obry@adacore.com>
28340 * Makefile.in (LIBGNAT_SRCS): Add seh_init.c.

28343 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28346 * Makefile.in: Link all gnat tools with -static-libgcc, since
28347 -shared-libgcc is now used by default on some systems (e.g. linux with
28349 Remove references to Makefile.prolog/generic, no longer used.
28351 2005-02-09 Vincent Celier <celier@adacore.com>
28353 * prj-makr.adb (Process_Directory): Put file name in canonical case
28354 before matching against the patterns.
28355 If gnatname has been invoked as <prefix>-gnatname
28356 then invoke the compiler as <prefix>-gcc, not just "gcc".
28358 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28360 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28361 with expansion disabled. The actual subtype is needed among other
28362 places when the selected component appears in the context of a loop
28363 bound, and denotes a packed array.
28364 (Operator_Check): Always use the first subtype in the
28365 error message, to avoid the appearance of internal base types.
28366 (Transform_Object_Operation): Copy each actual in full
28367 to the parameter associations of the constructed call, rather than
28368 using the shallow copy mechanism of New_Copy_List. This ensures that
28369 the chaining of named associations is done properly.
28370 (Complete_Object_Operation): Rewrite node, rather than
28371 replacing it, so that we can trace back to the original selected
28374 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28375 and calls that use object notation, if the called function is not
28376 declared in a withed unit, place the elaboration constraint on the
28377 unit in the context that makes the function accessible.
28378 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28379 imposes an elaboration constraint between two packages.
28381 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28383 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28384 views of a private type after handling its private dependents, to
28385 maintain proper stack discipline between entry and exit from the
28388 2005-02-09 Cyrille Comar <comar@adacore.com>
28390 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

28395 * s-tporft.adb (Register_Foreign_Thread): Initialize Task_Image[_Len]
28396 fields for foreign threads.

28401 recursion warnings when compiled with -gnatdm.
28403 2005-02-09 Robert Dewar <dewar@adacore.com>
28405 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28406 Slight fix to documentation of -gnaty with no parameters
28408 * xr_tabls.ads: Add ??? comment for missing overall comment
28410 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28411 we now use by default.
28413 * xsnames.adb: Adjust end of file test to look for five space followed
28414 by '#' instead of six spaces. The format of xsnames.adb was modified
28415 in the last update.
28417 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28420 * clean.adb: Minor reformatting.
28422 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28423 gnatname.adb: Minor reformatting
28424 Add 2005 to copyright output when utility is run
28426 * csets.adb: Eliminate obsolete comment
28428 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28431 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28433 2005-02-09 Sergey Rybin <rybin@adacore.com>
28435 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28436 the difference between compact and incompact layout and add the record
28437 representation clause to the example illustrating different layouts.
28438 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28439 component clauses").
28441 2005-02-09 Florian Villoing <villoing@adacore.com>
28443 * gnat_ugn.texi: Fix typos.
28444 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28446 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28447 in the generated documentation.
28449 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28451 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

28491 * exp_util.ads: Minor correction in comment.
28493 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28495 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28496 since this procedure is now too complex to be worth inlining.
28498 2005-02-09 Richard Henderson <rth@redhat.com>
28500 * utils.c (gnat_define_builtin): Remove.
28501 (gnat_install_builtins): Use build_common_builtin_nodes.

28743 2005-01-03 Olivier Hainque <hainque@adacore.com>
28745 * decl.c (compatible_signatures_p): New function. The intended purpose
28746 is to check if two function signatures for a call-site and a callee are

29278 (Remove_Next_Debug): Same fix
29280 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
29281 maintain back pointers now, though we did not used to, and comments
29283 (Prepend): Remove pragma Inline.
29284 (Remove_Next): Same cleanup
29286 2004-12-07 Thomas Quinot <quinot@adacore.com>
29288 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29289 used to record an implicit dereference as a read operation on its
29290 prefix when operating under -gnatc. Necessary to avoid spurious
29291 'variable assigned but never read' warnings in that mode.
29292 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29293 is a non-overloaded implicit dereference, call the above subprogram to
29294 ensure proper recording of references.
29296 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29298 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
29299 to be resolved later as part of Analyze_Iteration_Scheme's call to
29302 2004-12-07 Ed Schonberg <schonberg@adacore.com>
29304 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

29314 * g-socket.ads (Get_Host_By_Address, Get_Host_By_Name): Clarify
29315 documentation of the behaviour of these functions when passed an IP
29316 address that has no record in the system hosts database and no reverse

29336 2004-12-07 Vincent Celier <celier@adacore.com>
29337 Sergey Rybin <rybin@adacore.com>
29339 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
29340 Files" with the new tool and package names.
29341 Reformatting to suppress most of the warnings for line too long
29342 Document the new section "Project Search Path:" in the output of
29344 Add gnatmetric section
29346 2004-12-07 Vincent Celier <celier@adacore.com>
29348 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29349 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29350 and -eit to -ept. Added qualifier
29351 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29353 2004-11-27 Andreas Schwab <schwab@suse.de>
29355 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29357 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29359 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29360 internal implementation unit GNAT.Sockets.Thin,
29361 as their usage for sockets is non-portable (using the read and write
29362 functions from the system runtime library is fine on UNIX but won't
29363 work under Windows).
29365 * mingw32.h: Update copyright notice.
29367 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29369 * ada-tree.h: Minor reformatting of previous change to avoid lines
29370 longer than 79 characters.

29391 Style_Check_Order_Subprograms.
29393 2004-11-18 Arnaud Charlet <charlet@adacore.com>
29395 * adaint.h, adaint.c
29396 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
29398 Add also a cast to kill another warning.
29399 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
29400 parameter with the priority class of the parent process instead of
29401 always using the NORMAL_PRIORITY_CLASS.
29402 (__gnat_dup): New function.
29403 (__gnat_dup2): New function.
29404 (__gnat_is_symbolic_link): Enable the effective body of this
29405 function when __APPLE__ is defined.
29407 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
29410 2004-11-18 Olivier Hainque <hainque@adacore.com>
29412 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
29413 address of which may be used to represent "others" and "all others"
29414 choices in exception tables, instead of the current harcoded
29415 (void *)0 and (void *)1.
29416 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29418 * gigi.h (others_decl, all_others_decl): New decls representing the
29419 new Others_Value and All_Others_Value objects.
29420 (struct attrib): Rename "arg" component as "args", since GCC expects a
29421 list of arguments in there.
29423 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29424 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29427 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29428 others_decl and all_others_decl instead of hardcoded dummy addresses
29429 to represent "others" and "all others" choices, which is cleaner and
29430 more flexible with respect to the possible eh pointer encoding policies.
29432 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29433 (process_attributes): Account for the naming change of the "args"
29434 attribute list entry component.
29436 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29437 cumulating attributes for different entities into a single list.
29438 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29439 attributes for the current entity and propagate first subtype
29440 attributes to other subtypes.
29441 <E_Procedure>: Attribute arguments are attr->args and not
29442 attr->arg any more.
29443 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29444 argument provided, as this is what GCC expects. Use NULL_TREE instead
29447 2004-11-18 Robert Dewar <dewar@adacore.com>
29449 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
29450 Minor reformatting througout (including new function specs)
29451 Add ??? comments asking for clarification.
29453 2004-11-18 Thomas Quinot <quinot@adacore.com>
29455 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
29456 incomplete duplicate implementation of this subprogram from butil.
29458 2004-11-18 Thomas Quinot <quinot@adacore.com>

29461 procedures factors the common processing for building an RPC receiver
29462 for an RCI package or an RACW type.
29463 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
29464 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
29465 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
29467 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
29469 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
29471 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
29472 distribution subprogram identifiers that are either subprogram numbers

29475 string distribution identifiers assigned to a given subprogram.
29476 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29477 (Add_RAS_Dereference_TSS): Add comments.
29478 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29479 is not referenced yet because it will be used by the PolyORB DSA
29481 (Insert_Partition_Check): Remove fossile code.
29482 (First_RCI_Subprogram_Id): Document this constant.
29483 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29485 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29486 replaced with calls to Get_Library_Unit_Name_String. Previously there
29487 were several instances of the same code in different locations in the
29488 compiler; this checkin completes the replacement of all of these
29489 instances with calls to a common subprogram.
29490 Minor reformatting.
29492 * sem_dist.adb: Remove comment noting that RPC receiver generation
29493 should be disabled for RACWs that implement RASs.
29494 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.

29498 qualified name of a library unit into the name buffer.
29499 (Note_Possible_Modification): Generate a reference only
29500 if the context comes from source.
29502 * snames.ads (PCS_Names): New subtype corresponding to names of
29503 supported implementations of the Partition Communication Subsystem
29504 (PCS) (i.e. the runtime library support modules for the distributed

29518 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29519 (Expand_Pragma_Psect_Object): New procedure
29520 These procedures contain the revised and cleaned up processing for
29521 these two pragmas. This processing was formerly in Sem_Prag, but
29522 is more appropriately moved here. The cleanup involves making sure
29523 that the pragmas are properly attached to the tree, and that no
29524 nodes are improperly shared.
29526 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29527 pragmas to Exp_Prag, which is more appropriate.
29528 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29529 check for duplicates Remove use of Is_Psected flag, no longer needed.
29530 Use new Make_String_Literal function with string.
29532 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29533 that are functions return universal values, that have to be converted
29534 to the context type.
29535 Use new Make_String_Literal function with string.
29536 (Get_Stream_Convert_Pragma): New function, replaces the use of
29537 Get_Rep_Pragma, which had to be kludged to work in this case.
29539 * freeze.adb: Use new Has_Rep_Pragma function
29541 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29542 function with string.
29543 Use new Has_Rep_Pragma function.
29545 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29548 2004-11-18 Robert Dewar <dewar@adacore.com>
29550 * errout.ads, errout.adb: (First_Sloc): New function
29552 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29553 check (-gnatyx) instead of being included as a redundant construct
29556 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29557 Style_Check_Order_Subprograms.
29559 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29560 stylesw.adb: Add Style_Check_Xtra_Parens
29562 * usage.adb: Add line for -gnatyx (check extra parens)
29564 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29566 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29567 Robert Dewar <dewar@adacore.com>
29569 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29570 discriminant of a constrained subtype, analyze the copy of the
29571 corresponding constraint, because in some cases it may be only
29572 partially analyzed.
29573 Removes long-lived ??? comments.
29575 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29576 handled controlled or secondary-stack expressions within the
29577 iteration_scheme of a loop.
29579 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29580 bounds that may contain functions calls, to prevent memory leaks when
29581 the bound contains a call to a function that uses the secondary stack.
29582 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29583 generate temporaries for loop bounds that might contain function calls
29584 that require secondary stack and/or finalization actions.
29586 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29587 selected component and the selector is overloadable (not just a
29588 function) treat as function call, Analyze_Call will disambiguate if
29590 (Analyze_Selected_Component): Do not generate an actual subtype for the
29591 selected component if expansion is disabled. The actual subtype is only
29592 needed for constraint checks.
29593 (Analyze_Allocator): If restriction No_Streams is set, then do
29594 not permit objects to be declared of a stream type, or of a
29595 composite type containing a stream.
29597 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29598 No_Streams no longer prohibits with'ing this package.
29600 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29601 discriminants, but the parent base has unknown discriminants, there is
29602 no discriminant constraint to inherit. Such a discrepancy can arise
29603 when the actual for a formal type with unknown discriminants is a
29604 similar private type whose full view has discriminants.
29605 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29606 do not permit objects to be declared of a stream type, or of a
29607 composite type containing a stream.
29609 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29611 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29612 protected operations.
29614 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29615 generated name, it complicates decoding in gdb and hinders debugging
29616 of protected operations.
29617 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29618 flag for the protected entry barrier function.
29619 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info

29626 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29627 Darwin-specific section.
29629 * lang-specs.h: Change the placement of the %1 marker.
29630 Works around the fact that gcc adds -fPIC by default under Darwin.
29632 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29634 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29635 type of the object with the packed array type, set the Analyzed flag
29636 on the object if it is an entity or simple indexed component, to avoid
29637 spurious type errors.
29639 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29641 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29642 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29643 separate line from the version message.
29645 2004-11-18 Ed Falis <falis@adacore.com>
29647 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29649 (init_float): Eliminate initialization of floating point status for
29650 AE653. The instructions have no effect for vThreads.
29652 2004-11-18 Vincent Celier <celier@adacore.com>
29654 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29655 gnatbind is invoked with -shared.
29657 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29659 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29660 for Detect_Blocking which is redundant with the check done within the
29661 procedure Protected_Single_Entry_Call.
29662 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29663 Detect_Blocking which is redundant with the check done within the
29664 procedure Protected_Single_Entry_Call.
29666 2004-11-18 Vincent Celier <celier@adacore.com>
29668 * makegpr.adb (Compile): Put the compiling switches (in package
29669 Compiler and on the command line) immediately after "-c", instead of
29670 at the end of the command line invocation of the compiler, when
29671 compiling a non-Ada file.
29672 (Build_Global_Archive): When there is no need to rebuild the archive,
29673 set Global_Archive_Exists, so that the archive is passed to the linker
29676 2004-11-18 Robert Dewar <dewar@adacore.com>
29677 Sergey Rybin <rybin@adacore.com>
29680 Remove extra paren check from list of checks for redundant constructs
29681 Add documentation of new -gnatyx style check (check extra parens)
29682 Remove paragraph about gnatelim debug options.
29684 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29685 objects rather than forbidding dependencies on the package Ada.Streams.
29687 * sinfo.ads: Add ??? note that we should document pragmas passed to
29690 * g-expect.ads: Fix a few typos in the comments.
29692 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29694 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29697 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29699 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29701 2004-11-07 Andreas Schwab <schwab@suse.de>
29703 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29705 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29708 * Makefile.in (darwin): Set soext to .dylib.
29710 2004-10-26 Vincent Celier <celier@gnat.com>
29711 Thomas Quinot <quinot@act-europe.fr>
29713 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29714 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29715 there is no use of GNAT.Sockets.Constants.
29716 Remove remaining pragma Import for C_Write
29717 Remove C_Read and C_Write from internal implementation unit
29718 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29719 the read and write functions from the system runtime library is fine
29720 on UNIX but won't work under Windows).
29722 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29723 (Check_Selector): Use C_Recv instead of C_Read.
29724 Selectors are the GNAT.Sockets abstraction to perform a select()
29725 call on a set of descriptors. To allow abortion of an ongoing
29726 select operation, some data is written to a dedicated socket that
29727 is always monitored.
29728 Under Windows, the write and read library functions cannot operate
29729 on sockets, so we need to use send and recv instead, which is portable
29730 across all supported platforms.
29732 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29733 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29734 (using the read and write functions from the system runtime library is
29735 fine on UNIX but won't work under Windows).
29737 2004-10-26 Nicolas Setton <setton@act-europe.fr>

29743 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29744 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29747 * Makefile.in: Add support for building shared libraries under Darwin.
29748 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29749 the low level EH init subprogram to be called from __gnat_initialize.
29751 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29752 indicates which options to pass to the archive indexer.
29754 * mlib-utl.adb: Add support for calling ranlib with additional
29755 options. This is needed for instance under Mac OS X.
29756 (Ranlib_Options): New global variable, used to store the potential
29757 options to pass to ranlib.
29758 (Ar): Use Ranlib_Options when spawning ranlib.
29759 (Initialize): Set the value of ranlib option.
29761 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29763 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29764 instead of 8K, to reflect the real potential needs for stack-checking
29767 2004-10-26 Pascal Obry <obry@gnat.com>
29769 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29771 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29772 Windows only the initial thread stack size can be set so it is good to
29773 start we a low stack size.
29774 The OS will adjust the size as needed.
29776 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29777 Nicolas Setton <setton@act-europe.fr>
29779 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29780 "__unix__" instead of "unix".
29781 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29782 sections were just mistakenly ignored. The former is
29783 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29784 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29785 of hpux. This prevents an unwanted definition of the symbol
29786 convert_addresses in adaint.o.
29788 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29790 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29791 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29793 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29795 * a-filico.ads, a-filico.adb: fix incorrect header.
29797 2004-10-26 Javier Miranda <miranda@gnat.com>
29799 * a-ststio.ads: Fix typo in identifier
29801 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29803 * sem_ch4.adb: Minor reformatting.
29805 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29807 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29808 enabled, check the result of unary and binary operations when the
29809 expression is the right-hand side of an assignment.
29811 2004-10-26 Vincent Celier <celier@gnat.com>
29813 * clean.adb (Delete): Do not output warnings when in quiet output and
29814 not in verbose mode.
29815 (Force_Deletions): New Boolean flag, defaulted to False
29816 (Delete): Only delete a file if it is writable, and when
29817 Force_Deletions is True.
29818 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29819 (Usage): Line for new switch -f
29820 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29823 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29825 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29826 JM type only if its size matches that of the wrapper. When a size is
29827 prescribed and the field is not aliased, remove the wrapper of a JM
29828 type only if the size is not greater than that of the packed array.
29829 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29832 2004-10-26 Geert Bosch <bosch@gnat.com>
29834 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29835 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29836 (Pred): Implement in terms of Succ.
29838 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29840 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29841 unchecked conversion is safe for in-place use if the expression of the
29842 conversion is safe.
29843 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29844 be expandable in place even if the aggregate does not come from source.
29845 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29846 designated object of an allocator in place, rather than building it
29847 first on the stack. The previous scheme forces a full copy of the array,
29848 and may be altogether unsusable if the size of the array is too large
29849 for stack allocation.
29851 2004-10-26 Robert Dewar <dewar@gnat.com>
29853 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29854 compares if the component is atomic.
29856 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29857 array assignment if the component type is atomic.
29859 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29860 Eric Botcazou <ebotcazou@act-europe.fr>
29862 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29863 is aliased and is a by_reference type, do not pass by copy.
29864 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29865 detect whether the call is in the right side of an assignment or
29866 the expression of an object declaration. Recurse on component
29867 association within aggregates.
29868 Call it in the condition that determines whether the temporary is
29869 necessary for correct stack-checking.
29871 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29873 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29874 RACW_Type, used in the PolyORB version.
29875 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29876 version and the GARLIC version.
29878 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29879 Rename RCI_Info to RCI_Locator for better consistency between the
29880 GARLIC and PolyORB versions of the distributed systems annex.
29881 (DSA_Implementation_Name): This enumeration lists the possible
29882 implementations of the Partition Communication Subsystem for the
29883 Distributed Systems Annex (DSA). The three available implementations
29884 are the dummy stub implementation (No_DSA), and two versions based on
29885 two different distribution runtime libraries: GARLIC and PolyORB. Both
29886 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29888 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29891 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29892 between the GARLIC and PolyORB versions of the distributed systems
29894 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29896 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29898 * gnat1drv.adb: Suppress calling the back end when
29899 Frontend_Layout_On_Target is true.
29901 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29903 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29904 Set_Read_Only): New subprograms.
29905 These new routines allow the user to set or unset the Owner execute
29906 and Owner write permission flags on a file.
29908 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29909 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29911 2004-10-26 Matthew Gingell <gingell@gnat.com>
29913 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29915 2004-10-26 Pascal Obry <obry@gnat.com>
29917 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29918 memory before the faulting page we properly test the process read
29919 access for this address using appropriate Win32 routine.
29920 (HPUX sections): guard with "__hpux__" instead of "hpux".
29922 2004-10-26 Robert Dewar <dewar@gnat.com>
29924 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29925 entry parameter if pragma Unreferenced set, since we do not properly
29926 handle the case of multiple parameters.
29928 2004-10-26 Vincent Celier <celier@gnat.com>
29930 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29931 (Ada_Objects_Path.Add): For a library project, add to the object path
29932 the library directory only if there is no object directory or if the
29933 library directory contains ALI files.
29934 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29936 2004-10-26 Vincent Celier <celier@gnat.com>
29938 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29939 extension of library projects.
29941 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29942 path defaults to ".:<prefix>/lib/gnat".
29943 (Parse): For an extending all project, allow direct import of a project
29944 that is virtually extended.
29946 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29947 the specified name is directly imported, return its ID. Otherwise, if
29948 an extension of this project is imported, return the ID of the
29951 2004-10-26 Robert Dewar <dewar@gnat.com>
29953 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
29954 (Sub3): New procedure, used by Scaled_Divide
29955 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
29956 correct more than one instance of failure to propagate carries
29958 (Double_Divide): Handle overflow case of largest negative number
29959 divided by minus one.
29961 * s-arit64.ads (Double_Divide): Document that overflow can occur in
29962 the case of a quotient value out of range.
29965 2004-10-26 Robert Dewar <dewar@gnat.com>
29967 * s-bitops.adb (Bit_Eq): Remove redundant check.
29969 * s-bitops.ads: Minor comment updates
29970 Change some occurrences of Address to System.Address
29972 * s-carsi8.ads: Fix minor cut-and-paste error in comments
29974 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29976 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
29977 accessibility check to prefix that is a protected operation.
29979 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29981 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
29982 empty, post message on stub.
29984 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29985 Javier Miranda <miranda@gnat.com>
29987 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
29988 current instance appears within a unit that is directly in the context
29990 Used to determine whether the body of the instance should be analyzed
29991 immediately after its spec, to make its subprogram bodies available
29992 for front-end inlining.
29993 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
29994 constraint is not allowed on the component type (AARM 12.5.3(3))
29996 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29998 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
29999 'Storage_Pool): enhance, document & limit detection of non-sharable
30002 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30004 * s-pooglo.ads: Add more documentation now that this pool is properly
30007 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30009 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30010 or protected type with discriminants, do not constrain the
30011 corresponding record type if the subtype declaration has no
30012 discriminant constraints. This can be the case in source code, or in
30013 the subtype declaration created to rename an actual type within an
30016 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30018 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30019 different kind of stub (possibly wrong name for file), do not check
30021 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30022 includes call to some function that returns an unconstrained type, do
30025 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30027 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30028 appear in the code for the main unit. Dependencies among units in the
30029 context of the main unit are established when those other units are
30030 compiled. Otherwise spurious elaboration constraints can generate
30031 incorrect elaboration circularities.
30033 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30034 Ed Schonberg <schonberg@gnat.com>
30036 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30037 subprogram is called with a parameter that is not an object name. This
30038 situation arises for some cases of illegal code, which is diagnosed
30039 later, and in this case it is wrong to call Is_Aliased, as that might
30040 cause a compiler crash.
30041 (Explain_Limited_Type): Refine previous fix to include
30042 inherited components of derived types, to provide complete information.
30044 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30045 is the prival for a protected object.
30046 It is necessary to mark this entity as a variable, in addition to
30047 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30048 modified to avoid checking the Aliased flag on entities that are not
30049 objects. (Checking that flag for non-objects is erroneous and could
30050 lead to a compiler crash).
30052 2004-10-26 Robert Dewar <dewar@gnat.com>
30054 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30055 X_Frac = 0.5, then we know that the number X must be positive.
30056 (Succ): Remove the same redundant test, and also fix the primary test
30057 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30059 (Decompose): Add fuller comments to spec
30061 2004-10-26 Pascal Obry <obry@gnat.com>
30063 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30064 validity (process must have read access). Set to 0 in all other cases.
30065 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30066 violation on Win32.
30067 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30068 segmentation violation.
30070 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30072 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30073 whose type is a constructed subtype of an aliased object with an
30074 unconstrained nominal subtype, convert the actual to the constructed
30075 subtype before taking its address.
30077 2004-10-26 Vincent Celier <celier@gnat.com>
30079 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30080 (Is_Path_Name_Case_Sensitive): New function
30082 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30083 (Base_Name, Simple_Name, Current_Directory, Compose,
30084 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30087 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30088 Vasiliy Fofanov <fofanov@act-europe.fr>
30089 Vincent Celier <celier@gnat.com>
30091 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30092 "memory management issues" section and document some of the useful
30093 memory pools provided as part of the GNAT library.
30094 Remove "virtual" from declaration of A::method2 in
30095 the simple example of Ada/C++ mixed system.
30096 Library Projects may be virtually extended: their virtual extensions
30097 are not Library Projects.
30098 Added section on extending project hierarchies.
30100 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30102 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30104 (__gnat_portable_spawn): Remove const.
30106 * mingw32.h (MAXPATHLEN): Check for previous definition.
30108 2004-10-17 Matthias Klose <doko@debian.org>
30110 * gnatvsn.ads: Set gnat library version to 4.0.
30112 2004-10-05 Vincent Celier <celier@gnat.com>
30114 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30116 2004-10-04 Laurent Guerby <laurent@guerby.net>
30119 * Makefile.in: Define and use RANLIB_FLAGS.
30121 2004-10-04 Pascal Obry <obry@gnat.com>
30123 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30124 other x86 platforms).
30126 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30128 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30129 in general and triggers stack alignment adjustment for thread entry
30130 points on targets where this is necessary.
30132 2004-10-04 Bernard Banner <banner@gnat.com>
30135 * Makefile.in: Add section for powerpc linux
30136 Add variant i-vxwork-x86.ads
30138 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30140 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30142 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30143 table registration calls when need be. Ensures no reference to the crt
30144 ctors symbol are issued in the SJLJ case, which avoids possible
30145 undefined symbol errors in the case of modules to be statically linked
30148 2004-10-04 Javier Miranda <miranda@gnat.com>
30150 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30151 in-line the code corresponding to subprogram Analyze_Actuals. In
30152 addition, analyze the actuals only in case of subprogram call.
30154 2004-10-04 Ed Falis <falis@gnat.com>
30156 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30158 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30160 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30161 in the documentation.
30163 2004-10-04 Robert Dewar <dewar@gnat.com>
30165 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30167 (Analyze_Block_Statement): Add circuitry to detect following dead code
30168 (Check_Unreachable_Code): Handle case of block exit
30170 2004-10-04 Robert Dewar <dewar@gnat.com>
30172 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30173 (XMatchD): Avoid warning for Logic_Error call
30175 2004-10-04 Robert Dewar <dewar@gnat.com>
30177 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30178 consider expressions buried within a procedure actual to be an actual.
30179 This caused some blowups with uses of packed slices within a procedure
30182 2004-10-04 Robert Dewar <dewar@gnat.com>
30184 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30185 longer need to be initialized to zero.
30186 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30187 initialized to zero.
30189 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30190 considered valid, even if the representation is modular. That's correct
30191 now that we no longer initialize packed modular arrays to zero.
30193 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30194 suffixes. These are now documented as the only cases in which the
30195 debugger ignores outer records.
30196 Previously, the spec allowed arbitrary suffixes for this purpose.
30197 Change name of LJM to JM for packed array pad records
30198 Create separate section on packed array handling, and add a whole new
30199 set of comments to this section describing the situation with packed
30200 modular types and justification requirements depending on endianness.
30202 2004-10-04 Robert Dewar <dewar@gnat.com>
30204 * a-except.adb: Add a comment for last change
30206 * einfo.ads: Minor spelling correction in comment
30208 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30210 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30213 * sem_util.ads: Minor comment update
30215 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30217 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30218 Inline_Always when in Configurable_Run_Time mode.
30220 * sem_prag.adb (Process_Convention): If entity is an inherited
30221 subprogram, apply convention to parent subprogram if in same scope.
30222 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30223 when in Configurable_Run_Time mode.
30225 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30227 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30228 class_wide type after component list has been inherited.
30230 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30232 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30233 Denotes_Previous_Actual, to handle properly the case of a private
30234 actual that is also the component type of a subsequent array actual.
30235 The visibility status of the first actual is not affected when the
30236 second is installed.
30237 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30238 make fully recursive the treatment of formals of packages declared
30240 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30241 the above on exit from an instantiation.
30242 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30243 current instantiation which is now complete.
30244 (Analyze_Package_Instantiation): No instantiated body is needed if the
30245 main unit is generic. Efficient, and avoid anomalies when a instance
30246 appears in a package accessed through rtsfind.
30248 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30250 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30251 do not generate a declaration for a temporary if the call is part of a
30252 library-level instantiation.
30254 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30256 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30257 searching for a limited component to flag.
30259 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30260 expansion of Input, to account for the fact that the implicit call
30261 generated by the attribute reference must freeze the user-defined
30262 stream subprogram. This is only relevant to 'Input, because it can
30263 appear in an object declaration, prior to the body of the subprogram.
30265 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30266 expansion can proceed and further errors uncovered.
30267 (Minor clean up): Fix cases of using | instead of \ for continuation
30270 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30272 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.

30279 specified alignment before validating size.
30280 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30281 stripped-down declaration for the type of the inner field when making
30284 * utils.c (finish_record_type): Do not compute the size in units
30285 incrementally. Instead compute it once for the rep clause case.
30286 Use gcc_assert and gcc_unreachable.
30288 2004-10-04 Vincent Celier <celier@gnat.com>
30290 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30292 (Is_Valid_Path_Name): Take '/' as a directory separator.
30294 2004-10-04 Vincent Celier <celier@gnat.com>
30296 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30297 (Extended_Project) only if Extended_Project is defined, to avoid
30299 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30301 (Parse_Single_Project): Ditto.
30303 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30304 Add_To_Project_Path for virtual projects.
30306 2004-10-04 Vincent Celier <celier@gnat.com>
30308 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

30311 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30312 parameter Options_2.
30314 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30315 Build_Dynamic_Library with an empty Options_2.
30317 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no

30321 directory separator, if any.
30322 (Gprmake): Do not allow mains on the command line for library projects.
30323 Do not attempt to link when the project is a library project.
30324 (Library_Opts): New table to store Library_Options.
30325 (Build_Library): If Library_Options is specified, pass these options
30326 when building a shared library.
30328 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30330 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30331 the end of this procedure now that the unlock operation was inserted
30334 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30336 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30337 corresponding to the Preallocated_Stacks flags in System.
30338 (Get_Target_Parameters): Including the processing for

30349 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
30350 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30351 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30352 used to signal whether the compiler creates the required stacks and
30353 descriptors for the different tasks (when True) or it is done by the
30354 underlying operating system at run time (when False).
30355 It is initially set to False in all targets.
30357 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30358 if it is supported by the target.
30359 (Make_Task_Create_Call): Pass the stack address if it has been
30360 previously created. Otherwise pass a Null_Address.
30362 * snames.adb: Add _stack.
30364 * snames.ads: Add Name_uStack. Required to allow the expander to
30365 statically allocated task stacks.
30367 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30368 Stack_Address argument.
30369 Check that its value is equal to Null_Address because this target does
30370 not support the static stack allocation.

30379 * exp_dist.adb: Split declaration of asynchronous flag out of
30380 Add_RACW_Read_Attribute.
30381 Minor reformatting for better alignment with PolyORB version.
30382 Store the entity for the asynchronous flag of an RACW, rather than the
30383 expression, in the asynchronous flags table. This will allow this flag
30384 to be used in other subprograms beside Add_RACW_Read_Attribute.
30386 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30388 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30392 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30393 sockets constant MSG_NOSIGNAL (Linux-specific).
30394 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30395 all Send operations.
30396 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30397 from trigerring SIGPIPE.
30398 Rename components to avoid clash with Ada 2005 possible reserved
30400 (Check_Selector): When the select system call returns with an error
30401 condition, propagate Socket_Error to the caller.

30411 instead do this at freeze time (we won't do it if there is an address
30413 Change "pragma inline" to "pragma Inline" in information and error
30415 Minor reformatting.
30417 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30418 right way of doing things after all.
30419 (Freeze_Entity): For object, set Is_Public for imported entities
30420 unless there is an address clause present.
30422 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30424 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30425 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30426 ensures proper handling of types with rep clauses, which might have
30427 their TYPE_SIZE set already.
30429 2004-09-21 Robert Dewar <dewar@gnat.com>
30431 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30432 packed array types in both little- and big-endian cases. This change
30433 ensures that we no longer count on the unused bits being initialized
30434 for such types (and in particular ensures that equality testing will
30435 only read the relevant bits).
30436 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30437 These changes mean that we no longer need to initialize small packed
30439 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30440 optimization to an LJM field as to its parent field.
30442 * ada-tree.h, trans.c, utils.c, utils2.c:
30443 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30445 2004-09-20 Jan Hubicka <jh@suse.cz>
30447 * utils.c (gnat_finalize): Remove.
30448 (end_subprog_body): Directly call cgraph_finalize_function;
30449 do not lower the nested functions.
30451 2004-09-20 Robert Dewar <dewar@gnat.com>
30454 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30455 if an address clause is present, since that means that the Import
30458 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30460 * 5tsystem.ads: Removed, no longer used.
30462 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30463 Zack Weinberg <zack@codesourcery.com>
30465 * ada-tree.def: Use tree_code_class enumeration constants
30466 instead of code letters.

30484 an existing directory.
30485 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30486 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30487 Convert the result to File_Size.
30489 * prj.ads: (Project_Error): New exception
30491 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30492 Prj.Com, not from Osint.
30493 (Attrs, Package_Attributes): Tables moved to private part of spec
30494 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30496 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30497 Prj.Project_Error after call to Fail.
30498 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30499 Fail. Check that package name is not already in use.
30501 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30502 used by tools, not only by the project manager, and to indicate that
30503 exception Prj.Prj_Error may be raised in case of problem.
30504 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30506 (Attrs, Package_Attributes): Table instantiations moved from the body to
30507 the private part to be accessible from Prj.Attr.PM body.
30509 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30510 from new package Prj.Attr.PM.
30511 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30514 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
30516 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
30517 instead of Elaboration_Checks).

30562 pragmas recognized by GNAT.
30564 * gnat_rm.texi: Document pragma Detect_Blocking.
30566 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
30567 raise Program_Error if called from a protected operation.
30569 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30570 the protected action nesting level.
30571 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30572 protected action nesting level.
30573 (Unlock): When pragma Detect_Blocking is active decrease the protected
30574 action nesting level.
30576 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30577 Protected_Action_Nesting.
30579 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30580 Common_ATCB record. It contains the dynamic level of protected action
30581 nesting for each task. It is needed for checking whether potentially
30582 blocking operations are called from protected operations.
30583 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30584 Detect_Blocking is active or not in the partition.
30586 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

30596 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
30597 raise Program_Error if called from a protected operation, and increase
30598 the protected action nesting level.
30599 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
30600 Program_Error if called from a protected operation, and increase the
30601 protected action nesting level.

30607 the protected action nesting level.
30608 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
30609 Program_Error if called from a protected operation, and increase the
30610 protected action nesting level.

30616 protected action nesting level.
30618 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30619 insertion of the statement raising Program_Error. The run time
30620 contains the required machinery for handling that.
30622 * sem_util.ads: Change comment associated to procedure
30623 Check_Potentially_Blocking_Operation.
30624 This procedure does not insert a call for raising the exception because
30625 that is currently done by the run time.
30627 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30629 * init.c: Add the global variable __gl_detect_blocking that indicates
30630 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30631 making the pragma available at run time.
30632 (__gnat_set_globals): Pass and update the detect_blocking parameter.
30634 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
30635 pragma Detect_Blocking is active.
30637 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30639 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30640 DB is found in the ali file. Any unit compiled with pragma
30641 Detect_Blocking active forces its effect in the whole partition.
30643 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30644 Detect_Blocking is active and delay is called from a protected
30647 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30648 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30649 Detect_Blocking is active (0 otherwise).
30650 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30651 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
30654 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
30656 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30657 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30660 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30661 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30662 Update API in placeholder implemetation of s-parint to reflect changes
30663 in distribution runtime library.
30665 * sem_ch3.adb (Expand_Derived_Record): Rename to
30666 Expand_Record_Extension.
30668 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30669 primitive operations of potentially distributed object types that have
30670 non-controlling anonymous access formals.
30672 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30674 New implementation of expansion for remote access-to-subprogram types,
30675 based on the RACW infrastructure.
30676 This version of sem_dist is compatible with PolyORB/DSA as well as
30679 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30680 Asynchrronous that applies to a remote access-to-subprogram type, mark
30681 the underlying RACW type as asynchronous.
30683 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30684 __gnat_using_gnu_linker to 1.
30686 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30687 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
30688 GNAT.Perfect_Hash_Generators, and remove the empty
30689 GNAT.Perfect_Hash package.

30693 * exp_ch3.adb (Expand_Derived_Record): Rename to
30694 Expand_Record_Extension.
30695 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30696 a component declaration must remain attached at that point in the
30697 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30698 It is therefore necessary to take a copy of the expression when building
30699 the corresponding assignment statement in the init proc.
30700 As a side effect, in the case of a derived record type, we now see the
30701 original expression, without any rewriting that could have occurred
30702 during expansion of the ancestor type's init proc, and we do not need
30703 to go back to Original_Node.
30705 * exp_ch3.ads (Expand_Derived_Record): Rename to
30706 Expand_Record_Extension.
30708 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
30709 Returns the RACW type used to implement a remote access-to-subprogram
30711 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
30712 New subprograms. Used to create a proxy tagged object for a remote
30713 subprogram. The proxy object is used as the designated object
30714 for RAS values on the same partition (unless All_Calls_Remote applies).
30715 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30716 System.Partition_Interface.Get_Unique_Remote_Pointer.
30717 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30718 Renamed from Add_RAS_*_Attribute.
30719 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
30721 New implementation of expansion for remote access-to-subprogram types,
30722 based on the RACW infrastructure.
30724 * exp_dist.ads (Copy_Specification): Update comment to note that this
30725 function can copy the specification from either a subprogram
30726 specification or an access-to-subprogram type definition.
30728 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30730 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30731 in an instance, between an explicit subprogram an one inherited from a
30732 type derived from an actual.
30734 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30735 add a polling call if the subprogram is to be inlined by the back-end,
30736 to avoid repeated calls with multiple inlinings.
30738 * checks.adb (Apply_Alignment_Check): If the expression in the address
30739 clause is a call whose name is not a static entity (e.g. a dispatching
30740 call), treat as dynamic.
30742 2004-09-09 Robert Dewar <dewar@gnat.com>
30744 * g-trasym.ads: Minor reformatting
30746 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except
30747 packed arrays, since unused bits are expected to be zero for a

30752 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
30755 2004-09-09 Pascal Obry <obry@gnat.com>
30757 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30758 enable map file generation. Add the right option to generate the map
30759 file if Map_File is set to True.
30761 * gnatdll.adb (Gen_Map_File): New variable.
30762 (Syntax): Add info about new -m (Map_File) option.

31016 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
31017 discriminants that rename those of the parent, recover names of
31018 original discriminants for the constraint on the full view of the

31049 returning C.int, to avoid using a derived boolean type.
31051 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

31080 ignore overflows on low and high bounds of an index to also account for
31081 differences in signedness between sizetype and gnu_index_subtype.
31082 These are as legitimate as the ones caused by a lower TYPE_PRECISION

34999 complete assignment subtree which is now unnecessary, as the expansion
35000 of inlined call has been improved to preserve a consistent assignment
35001 tree. Note_Possible_Modification must be called only
35002 after checks have been applied, or else unnecessary checks will
35005 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35006 of explicit dereferences that do not Come_From_Source:

35008 pointer (an assignment to an implicit dereference must not be
35009 recorded as modifying the pointer);

35196 part has been scanned-out and it was present
35198 * par-ch3.adb, par-ch4.adb, par-ch6.adb: Give support to AI-231
35200 * sem_aggr.adb: (Check_Can_Never_Be_Null): New subprogram
35201 (Aggregate_Constraint_Checks): Generate conversion to the null-excluding
35202 type to force the corresponding run-time check
35203 (Resolve_Aggregate): Propagate the null-excluding attribute to the array
35205 (Resolve_Array_Aggregate): Carry out some static checks
35206 (Resolve_Record_Aggregate.Get_Value): Carry out some static check
35208 * sem_ch3.adb (Access_Definition): In Ada 0Y the Can_Never_Be_Null

35245 2004-03-29 Robert Dewar <dewar@gnat.com>
35247 * fname.adb, fname.ads, fname-sf.adb, fname-uf.adb, fname-uf.ads,
35248 gnat1drv.adb, lib.adb, lib.ads, lib-load.adb, lib-writ.adb,
35249 opt.ads, osint.adb, osint.ads, osint-c.adb, par.adb,
35250 par-ch10.adb, par-load.adb, par-prag.adb, sfn_scan.adb,

35259 * sem_ch12.adb: Add comment for previous change
35261 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
35263 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35264 executable name when not initialized. Otherwise, use its current value.
35266 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35267 initialize it to another executable name than the current one. This
35268 allows to configure paths for an executable name (gnatmake) different
35269 from the current one (gnatdist).
35271 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35273 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35274 current unit cannot be inlined if it appears in the body of a withed
35275 unit, to avoid order of elaboration problems in gigi.
35277 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35278 information for protected (wrapper) operation as well, to simplify gdb
35281 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35282 protected body, indicate that the entity for the generated spec comes
35283 from source, to ensure that references are properly generated for it.
35284 (Build_Body_To_Inline): Do not inline a function that returns a
35287 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
35288 apply convention to homonyms that are declared explicitly.
35290 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
35291 that renames an equality operator and the operands are overloaded,
35292 resolve them with the declared formal types, before rewriting as an
35295 2004-03-29 GNAT Script <nobody@gnat.com>
35297 * Make-lang.in: Makefile automatically updated
35299 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>

35318 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35320 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35321 attribute reference does not denote a subtype, it can be any
35322 expression that has a classwide type, potentially after an implicit
35323 dereference. In particular, the prefix can be a view conversion for
35324 a classwide type (for which Is_Object_Reference holds), but it can
35325 also be a value conversion for an access-to-classwide type. In the
35326 latter case, there is an implicit dereference, and the original node
35327 for the prefix does not verify Is_Object_Reference.
35329 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35330 conversion of a discriminant-dependent component of a mutable object
35333 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35335 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35336 inherited, has convention C, and has unconstrained array parameters,
35337 place the corresponding warning on the derived type declaration rather
35338 than the original subprogram.
35340 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35341 indication on renaming declaration, if formal has a box and actual
35344 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35345 determine whether to generate an implicit or explicit reference to
35346 the renamed entity.
35348 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35349 subprogram renaming comes from a defaulted formal subprogram in an
35352 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35354 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35355 value expressions to ensure that calls within a component definition
35356 will be checked (since those are evaluated during the record type's
35359 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
35361 * s-tpobop.adb: Code clean up:
35362 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

35381 Has_RACW, Is_Generic, etc.)
35382 (Output_Object, Gnatls): Take into account ALI files not attached to
35385 2004-03-22 Vincent Celier <celier@gnat.com>
35387 * gprep.adb: Change all String_Access to Name_Id
35388 (Is_ASCII_Letter): new function
35389 (Double_File_Name_Buffer): New procedure
35390 (Preprocess_Infile_Name): New procedure

35393 Call Process_Files to do the real job.
35395 2004-03-22 Robert Dewar <dewar@gnat.com>
35397 * prj-env.adb, prj-nmsc.ads, prj-proc.ads,
35398 s-stache.ads, s-stache.adb: Comment updates. Minor reformatting.
35400 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
35402 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
35403 case when the source contains only comments.
35405 2004-03-22 Ed Schonberg <schonberg@gnat.com>
35407 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35408 declaration for a child subprogram body that acts as a spec, indicate
35409 that the entity in the declaration needs debugging information.
35411 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35412 full view if the subtype is created for a constrained record component;
35413 gigi has enough information to construct the record, and there is no
35414 place in the tree for the declaration.
35416 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35417 serial number for the dummy body that is built for analysis, to avoid
35418 inconsistencies in the generation of internal names when compiling
35421 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35423 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35426 2004-03-22 GNAT Script <nobody@gnat.com>

35445 2004-03-20 Joseph S. Myers <jsm@polyomino.org.uk>
35448 * gnat_ug.texi: Add info directory category and entry.
35449 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
35450 gnat_ug_wnt.texi: Regenerate.
35452 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
35454 * ada-tree.h: Update copyright notice.
35455 Minor reformatting.
35457 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35459 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35460 as regular exception objects and not as mere integers representing the
35461 condition code. The latter approach required some dynamics to mask off
35462 severity bits, which did not fit well into the GCC table based model.
35463 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35464 exception data objects. We don't it and it would conflict with the other
35465 external symbol we have to generate for such exceptions.
35467 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35468 the special code for VMS exceptions, since these are now represented
35469 as regular exceptions objects.
35471 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35473 * decl.c (debug_no_type_hash): Remove.
35474 (gnat_to_gnu_entity, case E_Array_Type): Don't set and clear it.
35475 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
35477 2004-03-19 Laurent Guerby <laurent@guerby.net>
35479 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35480 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35482 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35484 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35485 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35486 (TYPE_RM_SIZE_INT): Directly use type.values.
35487 (TREE_LOOP_ID): Clean up check.
35488 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35489 TYPE_VALUES, not TYPE_FIELDS.

35498 * 5ataprop.adb, 5ftaprop.adb, 5htaprop.adb, 5itaprop.adb, 5staprop.adb,
35499 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
35500 Specific.Set instead of direct call to e.g pthread_setspecific.
35502 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35504 * adaint.c: Update comments.
35506 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35507 GNATLIB_SHARED for FreeBSD.
35509 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35511 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35512 When needed (stack checking) the stack size is retrieved
35513 from the VxWorks kernel.
35515 * Makefile.in: Flag -nostdinc is required when building the run time
35516 for avoiding looking for files in the base compiler.
35517 Add the VxWorks specific version of the package body for
35518 System.Stack_checking.Operations (5zstchop.adb).
35520 * Make-lang.in: Add the object file for
35521 System.Stack_Checking.Operations.
35523 * Makefile.rtl: Add object file for the package
35524 System.Stack_Checking.Operations.
35526 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
35528 * s-stache.ads, s-stache.adb: Move the operations related to stack
35529 checking from this package to package System.Stack_Checking.Operations.
35530 This way, stack checking operations are only linked in the final
35531 executable when using the -fstack-check flag.
35533 2004-03-18 Doug Rupp <rupp@gnat.com>
35535 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
35538 * 5qsystem.ads, 5xcrtl.ads: New files.
35540 2004-03-18 Vincent Celier <celier@gnat.com>
35542 * prj.adb (Reset): Reset hash table Files_Htable
35544 * prj-env.adb (Source_Paths, Object_Paths): New tables.
35545 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35546 the procedures Add_To_Path_File.
35547 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35548 making sure that each directory is present only once and, for object
35549 dirs, when a directory already present is added, the duplicate is
35550 removed and the directory is always put as the last in the table.
35551 Write the path files at the end of these accumulations.
35553 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35554 Files_Htable for all sources.
35556 * prj-proc.adb (Process): Remove restrictions between not directly
35557 related extending projects.
35559 2004-03-18 Emmanuel Briot <briot@act-europe.fr>

35565 parameter Trusted_Mode.
35567 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35569 * scn.adb (Determine_License): Take into account a degenerated case
35570 when the source contains only comments.
35572 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35574 * sem_warn.adb (Check_References): For a warning on a selected
35575 component that does not come from source, locate an uninitialized
35576 component of the record type to produce a more precise error message.
35578 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35580 * 3zsoccon.ads: Fix multicast options.
35582 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35585 2004-03-15 Robert Dewar <dewar@gnat.com>
35587 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
35588 pragma used for a private type.
35590 * lib-xref.adb (Generate_Reference): Do not generate warning if
35591 reference is in a different unit from the pragma Unreferenced.
35593 * 5vtpopde.adb: Minor reformatting
35594 Fix casing of To_Task_ID
35596 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35597 flag if we have an unchecked conversion to an access type in the same
35600 2004-03-15 Geert Bosch <bosch@gnat.com>
35602 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35603 imaginary parts, use Double precision throughout.
35605 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35606 we want to be able to compile run-time with -gnata for testing, but
35607 this may also be instantiated in user code that is compiled with -gnata.
35609 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35611 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35612 codes. Having a separate type for this is useful to enforce consistency
35613 throughout the various run-time units.
35614 (Exception_Data): Use Exception_Code for Import_Code.
35616 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
35617 Natural and Integer in various places.
35618 (Register_VMS_Exception): Use Base_Code_In to compute the exception code
35619 with the severity bits masked off.
35620 (Register_VMS_Exception): Handle the additional exception data pointer
35623 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
35624 component, now reflected by an exported accessor.
35625 (is_handled_by): New routine to compute whether the propagated
35626 occurrence matches some handler choice specification. Extracted out of
35627 get_action_description_for, and expanded to take care of the VMS
35629 (get_action_description_for): Use is_handled_by instead of an explicit
35630 complex condition to decide if the current choice at hand catches the
35631 propagated occurrence.
35633 * raise.h (Exception_Code): New type for C.
35635 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35636 System.Standard_Library.Exception_Code, to allow references from the
35637 pragma import/export expander.
35639 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35640 New accessors to allow easy access to GNAT exception data
35642 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35643 redundant Handled_By_Others component, helper for the personality
35644 routine which will now be able to call the appropriate exception data
35647 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35648 component of Standard_Exception_Type to be the closest possible to
35649 Exception_Code in System.Standard_Library, that we cannot get at this
35650 point. Expand a ??? comment to notify that this type node should
35651 probably be rewritten later on.
35653 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35654 registration call to include a pointer to the exception object in the
35657 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35658 instead of int and explicit bitmasks.
35660 2004-03-15 Vincent Celier <celier@gnat.com>

36650 Let finish_record_type decide instead.
36651 Don't make a bitfield if the field is to be addressable.
36652 Always set a size for the field if the record is packed, to ensure the
36653 checks for bitfield creation are triggered.
36654 (finish_record_type): During last pass over the fields, clear
36655 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
36656 not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P

36705 error when there are unusual characters (such as '!') in the paths.
36707 * Makefile.generic: When there are sources in Ada and the main is in
36708 C/C++, invoke gnatmake with -B, instead of -z.

37114 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37115 N_String_Literal node always references an E_String_Literal_Subtype
37116 entity. This may not be true in the future.
37117 (Possible_Bit_Aligned_Component): Move processing of
37118 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37120 * exp_ch6.adb (Expand_Thread_Body): Pick up

37125 (Type_May_Have_Bit_Aligned_Components): New function.

37165 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37166 ineffective elaborate all pragmas on non-visible packages (this
37167 happened when a renamed subprogram was called). Now the elaborate all
37168 always goes on the package containing the renaming rather than the one
37169 containing the renamed subprogram.
37171 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37172 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37198 -B is specified. Fail when there are only foreign mains in attribute

37231 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37233 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37234 all attributes, including read-only attribute.

37389 to __gnat_map_signal, imported from init.c to support
37390 signal -> exception mappings that depend on the vxWorks version.
37393 Created and exported __gnat_map_signal to support signal -> exception
37394 mapping that is dependent on the VxWorks version.

37427 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37428 bounds of a loop, create a separate block in order to generate proper
37429 cleanup actions to prevent memory leaks.
37431 * sem_res.adb (Resolve_Call): After a call to
37432 Establish_Transient_Scope, the call may be rewritten and relocated, in
37433 which case no further processing is needed.

37451 2003-12-08 Robert Dewar <dewar@gnat.com>
37453 * 7sintman.adb: Minor reformatting
37455 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37456 standard linker options to get standard libraries linked. We now plan
37457 to provide dummy versions of these libraries to match the appropriate
37458 configurable run-time (e.g. if a library is not needed at all, provide
37459 a dummy empty library).
37461 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37462 options (-L parameters and standard libraries). What we plan to do is
37463 to provide dummy libraries where the libraries are not required.
37465 * gnatbind.adb: Minor comment improvement
37467 2003-12-08 Javier Miranda <miranda@gnat.com>
37469 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37470 aggregate in the parent. Otherwise constants with limited aggregates

37472 It is required to call the corresponding IP subprogram in case of
37473 default initialized components.
37474 (Gen_Assign): In case of default-initialized component, generate a
37475 call to the IP subprogram associated with the component.
37476 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37477 of aggregate with default initialized components.
37478 (Has_Default_Init_Comps): Improve implementation to recursively check
37479 all the present expressions.
37481 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37482 to indicate that the initialization call corresponds to a
37483 default-initialized component of an aggregate.
37484 In case of default initialized aggregate with tasks this parameter is
37485 used to generate a null string (this is just a workaround that must be
37486 improved later). In case of discriminants, this parameter is used to
37487 generate a selected component node that gives access to the discriminant
37490 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37491 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37492 allocated aggregates with default-initialized components.
37494 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37495 the box notation is used in positional aggregates.

37537 Process nodes N_Comment.
37539 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37540 without comments and there are some comments, set the flag
37541 Unkept_Comments to True.
37542 (Scan): If there are comments, set the flag Unkept_Comments to True and
37543 clear the comments.
37544 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
37545 (Next_End_Nodes: New table

37573 Comment_Id and set Token to Tok_Comment when scanning a comment.
37574 (Set_Comment_As_Token): New procedure
37576 * sinput-p.adb: Update Copyright notice
37577 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

37582 * sem_aggr.adb: Add dependence on Exp_Tss package
37583 Correct typo in comment
37584 (Resolve_Aggregate): In case of array aggregates set the estimated
37585 type of the aggregate before calling resolve. This is needed to know
37586 the name of the corresponding IP in case of limited array aggregates.
37587 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37588 in case of default initialized array components.
37590 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

37610 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
37611 they are automatically generated by Make-lang.in and cause nothing but
37612 maintenance troubles.
37614 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
37616 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

37630 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
37631 to ensure that the kernel fills in the interrupted context structure
37632 before calling a signal handler, which is necessary to be able to
37633 unwind past it. Update the copyright notice.
37635 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37637 * a-elchha.ads: New file.
37639 * a-elchha.adb: New default last chance handler. Contents taken from
37640 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.

37721 redundant inclusion of EXTRA_HIE_NONE_TARGET_PAIRS, which is always
37722 included in HIE_NONE_TARGET_PAIRS.
37724 2003-12-03 Ed Schonberg <schonberg@gnat.com>
37727 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
37728 is legal in an instance, because legality is cheched in the template.
37731 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
37732 appplied to an unchecked conversion of a formal parameter.
37735 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

37749 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
37750 so that the debugger can reliably access the value of the parameter,
37751 and therefore is able to display the exception name when an exception
37752 breakpoint is reached.
37754 2003-12-01 Thomas Quinot <quinot@act-europe.fr>
37756 * fmap.adb: Fix typo in warning message.

39091 Remove the test against being in No_Run_Time_Mode before generating a
39092 call to Register_Tag. It is redundant with the test against the
39093 availability of the function Register_Tag.

39105 no main is specified on the command line and attribute Mains is not
39106 empty, only build the Ada main. If there is no Ada main, just compile
39107 the Ada sources and their closure.

39109 information, check that the source exists and, if it does, that the path
39110 is the actual path of a source of a project.

41300 (general) Add @./@: where approriate, and two spaces after the
41301 full stop at the end of a sentence. Use @samp markup when
41302 referring concrete lexical entities (keywords, attribute names
41303 etc.), and @syntax for ARM grammar elements. Use @r for English

41382 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
41383 need to force universal inlining for these cases.
41385 2001-12-19 Arnaud Charlet <charlet@gnat.com>
41387 * s-taprob.adb: Minor clean ups so that this unit can be used in

41688 2001-12-17 Laurent Pautet <pautet@gnat.com>
41691 Fix comment of Shutdown_Socket and Close_Socket. These functions
41692 should not fail silently because if they are called twice, this
41693 probably means that there is a race condition in the user program.
41694 Anyway, this behaviour is consistent with the rest of this unit.
41695 When an error occurs, an exception is raised with the error message
41696 as exception message.

43030 instead of the previous simple checksum algorithm.
43031 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43032 (Set_Source_Table): idem.
43035 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43036 instead of simple checksum.
43037 (CRC_Match): new function.
43038 (CRC_Error): new constant.
43040 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43041 a CRC now and not a simple checksum. A CRC uses lower-case hex
43042 letters, fixes ambiguity in parsing.
43044 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43045 is what this variable will store.
43047 * bcheck.adb: Change reference to chechsum in comments by CRC.
43048 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43049 rename All_Checksum_Match to All_CRC_Match. Change due to API
43050 renaming since now GNAT does not use a simple checksum but a
43051 CRC using GNAT.CRC32.
43053 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43054 now and not anymore a simple checksum.
43056 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
43059 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
43062 (Restore_Scan_State): rename Checksum to CRC.

43068 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
43070 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
43071 GNAT.CRC32). Update copyright notice.
43073 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
43074 GNAT.CRC32). Update copyright notice.
43077 (Accumulate_Checksum): removed.
43078 (Update): new procedure. Add a wide-character into the CRC.
43081 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
43082 (Load_File): fix initialization of S (change Source_Checksum to
43085 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
43086 Source_CRC in S initialization.
43088 * sinput.adb (Source_Checksum): renamed to Source_CRC.
43090 * sinput.ads (Source_Checksum): renamed to Source_CRC.
43091 Update comments for the CRC.
43093 * types.adb (Hex): Use lowercase for the letter part.
43095 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43096 for a word. This is currently used only for CRC. In previous version,
43097 the checksum was using a representation with all letter being
43098 upper-case. With the new implementation (using CRC) we do not remove
43099 the 32th bit of the CRC, so we can have an upper-case starting letter
43100 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43101 It is ambigous since the CRC was optional and could be followed by
43102 options like EB, EE. So now this routines uses lower-case letter for
43103 the hexadecimal representation. Strange enough only lower case letters
43104 where checked in Scan_ALI (even if this was not a possible case).
43106 * gnatvsn.ads (Library_Version): changed to 3.15a.
43108 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43111 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
43114 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
43115 Add 2001 to copyright notice
43116 (Accumulate_Checksum): Modify to use System.CRC32.
43118 * ali-util.ads: Redo changes of previous revision to continue to use
43119 the word Checksum. Add 2001 to copyright notice.
43121 * ali.adb: Undo some of previous changes, not needed.
43122 Keep the change for lower case letters in the checksum.
43124 * ali.ads: Undo previous change not needed.
43126 * bcheck.adb: Undo most of previous change, not needed.
43127 But do use Checksums_Match for checksum comparison.
43129 * gnatls.adb: Undo most of previous change, not needed.
43130 But do use Checksums_Match for comparing checksums.
43132 * lib-load.adb: Undo previous change, not needed.
43134 * lib-writ.adb: Undo previous change, not needed.
43136 * lib-writ.ads: Document that checksums use lower case,
43137 not upper case letters.

43141 * scans.ads: Undo previous change, not needed.
43143 * scn-nlit.adb: Undo previous changes, not needed.
43145 * scn-slit.adb: Undo previous change, not needed. Fix header format.

43152 * sinput-p.adb: Undo previous change, not needed.
43154 * sinput.adb: Undo previous change, not needed.
43156 * sinput-l.adb: Undo previous change, not needed.
43158 * sinput.ads: Undo previous change, not needed. Keep only comment
43159 on new checksum algorithm
43161 * Makefile.in: Add s-crc32 as needed, remove g-crc32.
