1066 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1067 Orig_Prev to Prev in the case where the actual is N_Function_Call or

3157 which is the default in GNAT's persistent storage implementation.
3159 2008-05-20 Ed Schonberg <schonberg@adacore.com>
3162 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
3163 convention from its base type, do not set the type to that of integer,

3228 the visible part of the spec of a remote types unit.

3230 New local subprogram Is_Valid_Remote_Object_Type, replaces
3231 Is_Recursively_Limited_Private.
3232 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
3233 non-controlling formals (and the return type, even though this is not
3234 explicit in the standard) must support external streaming.
3235 (Validate_RCI_Subprogram_Declaration): Enforce E.2.3(14) rules: same
3236 as above for of RAS types and RCI subprograms. (The return type is not

3241 * sem_util.ads, sem_util.adb
3242 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
3243 Is_Remote_Call_Interface to identify RACW types in a stable and
3244 consistent way. We used to rely in this predicate on the privateness of
3245 the designated type and its ancestors, but depending on the currently
3246 visible private parts, this caused false negatives. We now uniformly
3247 rely on checks made at the point where the RACW type is declared.

3261 Add missing escaping of all-caps word 'CPP' in error messages.
3262 (Build_Discriminated_Subtype): Do not inherit representation clauses
3263 from parent type if subtype already carries them, because they are
3264 inherited earlier during derivation and already include those that may
3265 come from a partial view.
3267 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
3268 Check the declarations of a subprogram body for proper deferred
3269 constant completion.

3286 access-to-class-wide type.

3292 when there is a use clause for the same entity in the context.
3293 (Analyze_Subprogram_Renaming): A renaming_as_body is legal if it is
3294 created for a stream attribute of an abstract type or interface type.

3302 (Add_One_Interp): Ignore any interpretation that is a primitive
3303 operation of an RACW stub type (these primitives are only executed
3304 through dispatching, never through static calls).
3305 (Collect_Interps): When only one interpretation has been found, set N's
3306 Entity and Etype to that interpretation, otherwise Entity and Etype may
3307 still refer to an interpretation that was ignored by Add_One_Interp,
3308 in which case would end up with being marked as not overloaded but with
3309 an Entity attribute not pointing to its (unique) correct interpretation.
3311 2008-05-20 Ed Schonberg <schonberg@adacore.com>
3314 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

3324 (Print_Itype): Do not modify the sloc of the component type of a
3325 (packed) array itype, because it is an unrelated type whose source
3326 location is independent of the point of creation of the itype itself.

3365 2008-05-20 Arnaud Charlet <charlet@adacore.com>

3368 equivalent representation, but has the advantage of allowing
3369 compilation of this file under 64 bits platforms.
3371 * s-os_lib.adb (Normalize_Pathname): Mark Cur_Dir constant.
3373 * s-osinte-irix.ads: (Alternate_Stack_Size): Add dummy declaration.

7368 view is an unconstrained array, this enforces consistency requirements
7370 (Layout_Type): For an access type whose designated type is a limited
7371 view, examine its declaration to determine if it is an unconstrained
7372 array, and size the access type accordingly.

7569 WITH clause on a private sibling.
7570 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
7571 child unit is a renaming, create an implicit with_clause on that

7669 Gary Dismukes <dismukes@adacore.com>
7671 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
7672 requeue statement is dispatching. Do not emit an error when the name is

7674 perform subtype conformance between the formals of the current entry
7675 and those of the target interface primitive.
7676 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
7677 Timed_Entry_Call): Analyze the triggering statement as the first step of
7678 the processing. If this is a dispatching select, postpone the analysis
7679 of all select statements until the Expander transforms the select. This
7680 approach avoids generating duplicate identifiers after the Expander has
7681 replicated some of the select statements. In case the Expander is
7682 disabled, perform regular analysis.
7683 (Check_Triggering_Statement): New routine.
7684 (Analyze_Requeue): Exclude any interpretations that are not entries when
7685 checking overloaded names in a requeue. Also test type conformance for

7694 for the defaulted actual.
7696 2007-12-13 Geert Bosch <bosch@adacore.com>
7698 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

8280 Add support for parsing multiple array index types info, or
8281 multiple inherited interfaces info. This information cannot be stored
8282 in Xref_Entity_Record, which only supports a single instance of Tref_*,

8301 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
8302 that handles use of 'Access and 'Unchecked_Access applied to
8303 actuals covering interface types. Such code is now
8304 centralized in Expand_N_Attribute_Reference.

8348 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info

8374 Runtime_Library_Dir.
8376 * prj-part.adb (Parse_Single_Project): Do not check the name of the
8377 config project against the user project names.

8380 not include a dot are always case insensitive.
8381 (Process_Declarative_Items): Ditto
8382 (Process_Project_Tree_Phase_1): Set Success to False in case an error is
8385 * prj-util.adb (Value_Of (In_Array)): When Force_Lower_Case_Index is
8386 True, compare both indexes in lower case.

8392 2007-10-15 Gary Dismukes <dismukes@adacore.com>
8394 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
8395 association for an access component, add an association with null as
8396 the expression. Remove testing for array subtypes and the setting in
8397 that case of Ctyp to the array component type, which prevented proper
8398 inclusion of an association for null-initialized arrays. Collapse
8399 condition that tests for array subtypes into just a test of
8400 Is_Partially_Initialized_Type (which already covers arrays anyway).
8402 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>

8417 * sem_ch4.adb: Minor code and comment reformatting.
8418 (Analyze_Allocator): When the designated type of an unconstrained
8419 allocator is a record with unknown discriminants or an array with
8420 unknown range bounds, emit a detailed error message depending on the
8421 compilation mode and whether the designated type is limited.

8544 2007-09-27 Eric Botcazou <ebotcazou@adacore.com>
8546 Mapped location support
8547 * back_end.adb (Call_Back_End): Pass information about source
8548 files instead of units to gigi.
8549 * gigi.h (struct File_Info_Type): New.
8550 (gigi): Rename and change type of number_units parameter, change
8551 type of file_info_ptr parameter.
8552 * trans.c (number_files): New global variable.
8553 (gigi): Rename and change type of number_units parameter, change
8554 type of file_info_ptr parameter.
8555 If mapped location support is enabled, create the isomorphic mapping
8556 between source files and line maps.
8557 (Sloc_to_locus): If mapped location support is enabled, translate
8558 source location into mapped location.
8559 (annotate_with_node): Rename into set_expr_location_from_node.

8585 * a-calend-vms.adb, a-calend.adb:
8586 Add a section on leap seconds control along with two entities used to
8587 enable and disable leap seconds support. The array Leap_Second_Times is
8588 now constant and contains hard time values pre-generated. Remove
8589 all elaboration code used to populate the table of leap seconds.
8592 Add entity Leap_Seconds_Support to the list of global run-time variables
8593 along with a comment on its usage and values.
8594 (Gen_Adainit_Ada): Add code to generate the declaration and import of
8595 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
8596 or one (enabled) depending on the presence of binder switch "-y".
8597 (Gen_Adainit_C): Add code to generate the declaration of external int
8598 __gl_leap_seconds_support. Set is value to zero (disabled) or one
8599 (enabled) depending on the presence of binder switch "-y".

8608 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
8609 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
8611 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
8613 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
8614 function which can be called by the debugger to interrupt the tasks of
8615 an Ada application asynchronously, as needed on VxWorks.
8616 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
8618 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
8619 renamed from Stop_All_Tasks. Update comments.

8629 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
8630 #include <sys/wait.h>.
8632 2007-09-26 Thomas Quinot <quinot@adacore.com>

8635 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
8637 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
8640 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
8642 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
8645 * sem_dist.ads: Minor comment fix
8647 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
8649 2007-09-26 Javier Miranda <miranda@adacore.com>
8650 Eric Botcazou <ebotcazou@adacore.com>
8653 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
8654 indirection added to the HT_Link component of the TSD. This is required
8655 to statically allocate the TSD.
8658 Minor reordering of the declarations in the private part. Required to
8659 add a level of indirection to the contents of the TSD component HT_Link.
8660 This is required to statically allocate the TSD.
8662 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
8663 Is_Statically_Allocated set from constant objects.
8664 Do not make exported constants created by the compiler volatile.
8665 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
8668 * trans.c (Identifier_to_gnu): For constants, unshare initializers
8669 before returning them.
8671 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
8672 public part of the package.
8673 (Make_DT): Move HT_Link component out of the TSD record. For this
8674 purpose Make_DT now declares a separate object that stores the
8675 HT_Link value, and initializes the TSD component with the address
8676 of this new object. The addition of this level of indirection is
8677 required to statically allocate the TSD because the TSD cannot
8678 have variable components.
8679 (Expand_Interface_Conversion): Improve the expanded code.
8680 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
8682 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
8683 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
8684 if we are building static dispatch tables then we must not generate
8685 extra code to register the primitive because the dispatch table will
8686 be built at the end of the library package; otherwise we notify that
8687 we cannot build the static dispatch table.
8689 2007-09-26 Robert Dewar <dewar@adacore.com>
8691 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

8706 for thunks associated with interface types.
8708 * einfo.ads: Improve documentatation of Is_Internal
8709 (Is_Thunk): New attribute applicable to subprograms. True for thunks
8710 associated with interface types.
8711 Extensive comment fixes regarding flags that appear in all entities. The
8712 documentation is now consistent for all such flags (there were a number
8713 of errors in the documentation in this regard).
8715 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
8717 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
8718 of these procedures are passed a function call that already has
8719 build-in-place actuals (testing new flag
8720 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
8721 the case where processing continues.
8722 (Expand_Call): If the call is generated from a thunk body then we
8723 propagate the extra actuals associated with the accessibility
8724 level of the access type actuals.
8726 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
8727 of each extra formal of a protected operation to reference the
8728 corresponding extra formal of the subprogram denoted by the
8729 operation's Protected_Body_Subprogram.
8731 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
8732 N_Function_Call nodes.
8734 2007-09-26 Robert Dewar <dewar@adacore.com>
8736 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
8738 * debug.adb: Add d.s flag.
8740 2007-09-26 Gary Dismukes <dismukes@adacore.com>
8742 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
8743 debug variable so that it won't be initialized when pragma
8744 Initialize_Scalars is in effect.
8746 2007-09-26 Gary Dismukes <dismukes@adacore.com>
8748 * freeze.adb (Freeze_Entity): Remove check for preelaborable
8749 initialization of a full view. This is moved to
8750 Analyze_Package_Specification.
8752 * sem_ch7.adb (Analyze_Package_Specification): Add check for
8753 preelaborable initialization of a full view in entity loop.
8754 (Uninstall_Declarations): If entity is a use-visible compilation unit,
8755 its child units are use-visible only if they are visible child units.
8757 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
8758 whether an expression can be used within a type declaration that
8759 requires preelaborable init.
8760 (Check_Components): Replace inline code that does partial checking for
8761 preelaborable default expressions with call to
8762 Is_Preelaborable_Expression.
8763 (Has_Preelaborable_Initialization): In the case of a generic actual
8764 subtype, (that is, Is_Generic_Actual is True), return the result of
8765 applying Has_Preelaborable_Initialization to the generic actual's base
8768 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
8770 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
8771 call to Jan_1_Day _Of_Week to optimize its performance.
8772 (Is_Leap): Move the routine to the scope of Week_In_Year.
8773 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
8774 weekday on which January 1 falls of Year - 1 and Year + 1. This function
8775 avoids calling Time_Of and Split, thus making it more efficent.
8776 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
8778 * g-calend.ads (Week_In_Year): Change comment to reflect new
8781 2007-09-26 Emmanuel Briot <briot@adacore.com>
8783 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
8784 Command_Line): New types
8785 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
8786 support for defining how switches can be grouped on a command line (as
8787 is the case for -gnatw... for GNAT), and how simple switches can be
8788 used as aliases for more complex switches (-gnatwa is same as
8790 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
8791 (Start, Current_*): New subprograms
8792 Added support for parsing an array of strings in addition to the real
8794 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
8795 be moved from the body to the private part of the spec.
8796 (*): All subprograms now have an extra parameter with default value to
8797 specify which parser should be used. For backward compatibility, it
8798 defaults to parsing the command line of the application. They were also
8799 modified to properly handle cases where each of the argument does not
8800 start at index 1 (which is always true for Ada.Command_Line, but not
8801 when processing any Argument_List).
8802 (Free): New subprogram
8803 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
8804 Argument): New subprograms
8805 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
8806 special characters like ':', '=',... are now handled in a single place,
8807 which makes the code more extensible eventually.
8808 (Getopt, Full_Switch): When the switch was returned as part of the
8809 special character '*', make sure it is prepended by the switch character
8810 ('-' in general), so that the application knows whether "foo" or "-foo"
8811 was specified on the command line.
8813 2007-09-26 Florian Villoing <villoing@adacore.com>
8815 * g-dirope.adb (Remove_Dir): In case we are removing directories
8816 recursively, make sure that if an exception is raised during the
8817 processing, the current working directory is reset to its initial
8818 value before propagating the exception.
8820 2007-09-26 Vincent Celier <celier@adacore.com>
8822 * gnatbind.adb: If there are several ALI files specified and there is
8823 a main program to bind, the first ALI is expected to contain the main
8824 subprogram and the names of the binder generated files will be derived
8825 from the first ALI file name.
8826 (Gnatbind): Fix insertion character in invocation of Error_Msg
8828 2007-09-26 Vincent Celier <celier@adacore.com>
8830 * gnatcmd.adb (Check_Files): Do not include sources that have been
8831 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
8833 2007-09-26 Ed Schonberg <schonberg@adacore.com>
8835 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
8836 information about each of its index types, following the type
8837 reference for its component type.
8839 2007-09-26 Vincent Celier <celier@adacore.com>
8841 * make.adb: (Kill): New procedure (__gnat_kill imported)
8842 (Running_Compile, Outstanding_Compiles): Global variables that
8843 were previously local to procedure Compile_Sources.
8844 (Sigint_Intercepted): Send signal SIGINT to all outstanding
8845 compilation processes.
8847 (Gnatmake): If project files are used, create the mapping of all the
8848 sources, so that the correct paths will be found.
8850 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
8852 2007-09-26 Vincent Celier <celier@adacore.com>
8854 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
8856 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
8857 Replace components Compiler_Min_Options and Binder_Min_Options with
8858 Compiler_Required_Switches and Binder_Required_Switches in record
8860 Remove components Default_Language and Config in Project_Tree_Data,
8863 * prj-attr.adb: New attributes Required_Switches (<language>) in
8864 packages Compiler and Binder.
8866 * prj-nmsc.adb: Major rewrite of the processing of configuration
8867 attributes for gprbuild. No impact on GNAT tools.
8869 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
8870 process configuration attributes: this is done in Prj.Nmsc.Check.
8871 (Recursive_Process): Make a full copy of packages inherited from project
8872 being extended, instead of a shallow copy.
8873 (Process_Project_Tree_Phase_1): New procedure
8874 (Process_Project_Tree_Phase_1): New procedure
8875 (Process): Implementation now uses the two new procedures
8877 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
8878 from the project config, not the tree config that no longer exists.
8880 2007-09-26 Vincent Celier <celier@adacore.com>

9209 potentially be called.
9210 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9211 body for 'Output when the type is abstract (only the creation of the
9212 body for 'Input is excluded when the type is abstract).
9213 (Stream_Operation_OK): Add an additional condition in the return
9214 statement, so that False will be returned for TTS_Stream_Input if the
9215 associated tagged type is an abstract extension. Add comments for
9217 (Expand_N_Object_Declaration): For the case of a shared passive
9218 variable, insert init proc call only after the shared variable
9219 procedures have been processed, because the IP call needs to undergo
9220 shared passive variable reference expansion, which requires these
9221 procedures to be available (and elaborated).

9237 to remove other spurious ambiguities on arithmetic operations involving
9238 literals and addresses, on systems where Address is a visible integer
9239 type, when the operator is called in functional notation.
9240 (Try_Primitive_Operation): Within an instance, a call in prefixed form
9241 is legal when the types match, even if the operation is currently
9244 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9246 * sem_ch12.adb (Build_Local_Package): A formal package with no
9247 associations is legal if all formals have defaults. It is not

9366 (Write_Entity_Flags): Write the status of flag Is_Raised.
9367 (Is_Descendent_Of_Address): New entity flag, to simplify handling of

9389 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
9390 library-level package renaming, pass the declaration associated with
9391 the renaming's special debug variable to Qualify_Entity_Names to ensure
9392 that its encoded name is properly qualified.
9394 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
9395 occurring in the list of entities to qualify, and do not attempt to
9396 traverse an entity list in that case. Variables associated with
9397 ` library-level package renamings can now occur in the table.

9423 avoid very deep recursion in the front end, which was causing stack
9426 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
9427 string, and the right operand is a string literal (the case of "" &
9428 "..."), optimize by avoiding copying the right operand -- just use the
9429 value of the right operand directly.
9431 * stringt.adb (Store_String_Chars): Optimize by growing the
9432 String_Chars table all at once, rather than appending characters one by
9434 (Write_String_Table_Entry): If the string to be printed is very long,
9435 just print the first few characters, followed by the length. Otherwise,
9436 doing "pn(n)" in the debugger can take an extremely long time.
9438 * sem_prag.adb (Process_Interface_Name): Replace loop doing
9439 Store_String_Char with Store_String_Chars.

9458 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
9459 flag, for effiency. It is called when analyzing arithmetic operators
9460 and also for actuals in calls that are universal_integers. The flag is
9461 set for the predefined type address, and for any type or subtype
9464 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
9465 Universal_Integer, when the formal is a descendent of address and the
9466 call appears in user code.

9533 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
9534 associated with Standard_Debug_Renaming_Type, to be used as the type of
9535 the special variables whose names provide debugger encodings for
9536 renaming declarations.
9538 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
9539 (Set_Debug_Renaming_Link): Change to set Node25.

9546 (Debug_Renaming_Declaration): Replace creation of an enumeration type
9547 and literal with creation of a variable of type
9548 Standard_Debug_Renaming_Type whose name encodes both the renamed object
9549 and the entity of the renaming declaration.
9550 (Qualify_Entity_Name): Add the delayed qualification of the entity name
9551 part of the name of a variable that has a Debug_Renaming_Link.

9558 Ed Schonberg <schonberg@adacore.com>
9559 Javier Miranda <miranda@adacore.com>
9561 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
9562 ancestor part given by an aggregate to test for an unchecked conversion,
9563 since this can occur in some cases when the ancestor part is a function
9564 call, and we don't want to fall into the recursive call to this
9565 procedure in that case.
9567 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
9568 stream attributes on limited types to account for user-specified
9569 attributes as well as whether Input (resp. Output) becomes available
9570 due to Read (resp. Write) being available for the type. Change Boolean
9571 variable to the more accurate name
9572 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
9573 double-"not" predicate at beginning of return statement to more
9574 understandable form.
9576 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
9577 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
9578 in a block statement and use that as the first statement of the
9579 expanded return rather than incorrectly using the handled sequence as
9580 the first statement.
9582 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
9583 operation, generate an explicit freeze node for it rather than
9584 generating extra formals, to ensure that gigi has the proper order of
9585 elaboration for anonymous subtypes in the signature of the subprograms.
9586 (Build_In_Place_Formal): Move assertion to beginning of loop.
9587 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
9588 applied to a function call (occurs for some cases of 'Input).
9589 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
9590 applied to a function call (occurs for some cases of 'Input).
9592 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
9593 2005, generate an extended return statement enclosing the result object
9596 * freeze.adb (Freeze_Record_Type): Extend the current management of
9597 components that are access type with an allocator as default value: add
9598 missing support to the use of qualified expressions of the
9599 allocator (which also cause freezing of the designated type!)
9600 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
9601 dispatching operation, since extra formals may be needed by calls to
9602 build-in-place functions (such as stream 'Input).
9604 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
9605 formals for 'Constrained and accessibility level in the case of a
9606 predefined dispatching operation.
9608 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
9609 point, no need to find the parent node.
9611 2007-08-16 Javier Miranda <miranda@adacore.com>
9613 * exp_attr.adb (Attribute_Priority): Add missing support for entries
9616 2007-08-16 Javier Miranda <miranda@adacore.com>
9618 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
9619 is not really required and can introduce regression with the debugger.
9620 The original problem is fixed with the patch written for checks.adb.
9622 2007-08-16 Thomas Quinot <quinot@adacore.com>
9624 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
9625 Range_Check on Allocated_Table.

9629 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
9630 Including_Non_Switch set to False.
9631 (Gnatmake): For the compiler, call Test_If_Relative_Path with
9632 Including_Non_Switch set to False.
9634 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
9635 parameter Including_Non_Switch, defaulted to True. When
9636 Including_Non_Switch is False, options that are not switches and
9637 appear as relative path are not converted to absolute paths.

9652 from the immediate ancestor of Main_Unit_Entity.
9653 (Install_Limited_Withed_Unit): Do not install the limited view of
9654 package P if P is reachable through an ancestor chain from package C
9655 and C also has a with clause for P in its body.
9656 (Has_Limited_With_Clause): New routine.
9657 (Has_With_Clause): New routine.
9659 2007-08-16 Ed Schonberg <schonberg@adacore.com>
9661 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
9662 generic for an enclosing instance is a global reference, even though
9663 its scope is the enclosing instance.

9666 Javier Miranda <miranda@adacore.com>
9668 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to

9686 Bob Duff <duff@adacore.com>
9687 Nicolas Setton <setton@adacore.com>
9689 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
9690 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
9691 the statement which is being resolved comes from a predefined library
9692 unit, all non-predefined library interpretations are skipped.
9693 (Resolve_Op_Concat): If string concatenation was folded in the parser,
9694 but the "&" is user defined, give an error, because the folding would
9697 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
9698 the parser has folded a long sequence of concatenations of string
9701 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
9702 and "JMP_BUF" variables as artificial.
9703 (N_String_Literal): Do not use alloca for very long string literals. Use
9704 xmalloc/free instead. Otherwise the stack might overflow.

9751 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
9752 Suppress unmodified in-out parameter warning in some cases
9753 This patch is a also fairly significant change to the way suppressible
9756 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
9757 needed for access to concurrent record types generated by the expander.
9758 (Generate_Range_Check): When generating a temporary to capture the
9759 value of a conversion that requires a range check, set the type of the
9760 temporary before rewriting the node, so that the type is always
9761 properly placed for back-end use.
9762 (Apply_Float_Conversion_Check): Handle case where the conversion is
9764 (Get_Discriminal): Code reformatting. Climb the scope stack looking
9765 for a protected type in order to examine its discriminants.

9783 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
9784 aggregate code before allocator, and ahead of declaration for
9785 temporary, to prevent access before elaboration when the allocator is
9786 an actual for an access parameter.
9787 (Expand_N_Type_Conversion): On an access type conversion involving an
9788 access parameter, do not apply an accessibility check when the
9789 operand's original node was an attribute other than 'Access. We now
9790 create access conversions for the expansion of 'Unchecked_Access and
9791 'Unrestricted_Access in certain cases and clearly accessibility should
9792 not be checked for those.
9794 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
9795 includes a type conversion of a packed component that has been expanded,
9796 recover the original expression for the object, and use this expression
9797 in the post-call assignment statement, so that the assignment is made
9798 to the object and not to a back-end temporary.
9799 (Freeze_Subprogram): In case of primitives of tagged types not defined
9800 at the library level force generation of code to register the primitive
9801 in the dispatch table. In addition some code reorganization has been
9802 done to leave the implementation clear.
9803 (Expand_Call): When expanding an inherited implicit conversion,
9804 preserve the type of the inherited function after the intrinsic
9805 operation has been expanded.
9807 * exp_ch2.ads, exp_ch2.adb
9808 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
9809 of an entry formal appearing in an assignment statement does not assign
9811 (Expand_Current_Value): Instead of calling a routine to determine
9812 whether the prefix of an attribute reference should be optimized or
9813 not, prevent the optimization of such prefixes all together.
9815 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
9816 component whose prefix is known to be of an access type is an implicit
9817 dereference and does not assign to the prefix.

9829 node, to prevent errors when complex expression is copied.
9830 Fix mishandling of multiple levels of parens
9832 * sem_aggr.adb: Create a limited view of an incomplete type, to make
9833 treatment of limited views uniform for all visible declarations in a
9834 limited_withed package.

9836 make an entry into table to link associated node and new itype.
9837 (Resolve_Record_Aggregate): Do not add an others box association for a
9838 discriminated record component that has only discriminants, when there
9839 is a box association for the component itself.

9884 attribute with constants.
9885 (Write_Field26_Name): Handle attribute Related_Interface in constants.
9886 Warn on duplicate pragma Preelaborable_Initialialization
9888 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
9889 generation of a freezing node to ensure proper management of null
9890 excluding access types in the backend.
9891 (Create_Extra_Formals): Test base type of the formal when checking for
9892 the need to add an extra accessibility-level formal. Pass the entity E
9893 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
9894 originally being done in a couple of cases), to ensure that the
9895 Extra_Formals list gets set on the entity E when the first entity is
9897 (Conforming_Types): Add missing calls to Base_Type to the code that
9898 handles anonymous access types. This is required to handle the
9899 general case because Process_Formals builds internal subtype entities
9900 to handle null-excluding access types.
9901 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
9902 functions that need it, even when not marked Requires_Overriding.
9903 Improve warnings for in out parameters
9904 (Analyze_Function_Return): Warn for disallowed null return
9905 Warn on return from procedure with unset out parameter
9906 Ensure consistent use of # in error messages
9907 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
9908 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
9909 the implicit conversion of the expression done for anonymous access
9910 types. This is required to generate the code of the null excluding
9911 check (if required).
9913 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
9914 A formal parameter is never publicly referenceable outside of its body.
9915 (Check_References): For an unreferenced formal parameter in an accept
9916 statement, use the same warning circuitry as for subprogram formal
9918 (Warn_On_Unreferenced_Entity): New subprogram, taken from

9922 (Check_References): Do not give IN OUT warning for dispatching operation
9923 Improve warnings for in out parameters
9924 (Test_Ref): Check that the entity is not undefinite before calling
9925 Scope_Within, in order to avoid infinite loops.
9926 Warn on return from procedure with unset out parameter
9927 Improved warnings for unused variables
9929 2007-08-14 Robert Dewar <dewar@adacore.com>
9930 Javier Miranda <miranda@adacore.com>
9931 Gary Dismukes <dismukes@adacore.com>
9933 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
9934 (Expand_N_Attribute_Reference): Further unify the handling of the
9935 three forms of access attributes, using common code now for all three
9936 cases. Add a test for the case of applying an access attribute to
9937 an explicit dereference when the context is an access-to-interface
9938 type. In that case we need to apply the conversion to the prefix
9939 of the explicit dereference rather than the prefix of the attribute.
9940 (Attribute_Version, UET_Address): Set entity as internal to ensure
9941 proper dg output of implicit importation.
9942 (Expand_Access_To_Type): Removed.
9943 (Expand_N_Attribute_Reference): Merge the code from the three cases
9944 of access attributes, since the processing is largely identical for
9945 these cases. The substantive fix here is to process the case of a
9946 type name prefix (current instance case) before handling the case
9947 of interface prefixes.

9951 Javier Miranda <miranda@adacore.com>
9952 Robert Dewar <dewar@adacore.com>
9954 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
9955 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
9956 type that is an anonymous access to controlled object, establish
9957 an associated finalization chain to avoid corrupting the global
9958 finalization list when a dynamically allocated object designated
9959 by such a component is deallocated.
9960 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
9961 functions that need it, even when not marked Requires_Overriding.
9962 (Initialize_Tag): Replace call to has_discriminants by call to
9963 Is_Variable_Size_Record in the circuitry that handles the
9964 initialization of secondary tags.

9966 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
9967 Suppress_Initialization pragma for a derived type.
9968 (Is_Variable_Size_Record): New subprogram.
9969 (Build_Offset_To_Top_Functions): New implementation that simplifies the
9970 initial version of this routine and also fixes problems causing
9971 incomplete initialization of the table of interfaces.
9972 (Build_Init_Procedure): Improve the generation of code to initialize the
9973 the tag components of secondary dispatch tables.
9974 (Init_Secondary_Tags): New implementation that simplifies the previous
9975 version of this routine.
9976 (Make_DT): Add parameter to indicate when type has been frozen by an
9977 object declaration, for diagnostic purposes.
9978 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
9979 diagnose attemps to freeze a subprogram when some untagged type of its

9981 (Freeze_Array_Type): Generate init proc for packed array if either
9982 Initialize or Normalize_Scalars is set.
9983 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
9984 constructing the new profile, copy the null_exclusion indicator for each
9985 parameter, to ensure full conformance of the new body with the spec.
9987 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
9988 Create wrappers for constructor functions that need it, even when not
9989 marked Requires_Overriding.

10002 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10003 (Write_Overloads): Output the abstract operator if present.
10004 (Add_Entry): Before inserting a new entry into the interpretation table
10005 for a node, determine whether the entry will be disabled by an abstract
10007 (Binary_Op_Interp_May_Be_Hidden): New routine.
10008 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10010 (Function_Interp_May_Be_Hidden): New routine.
10011 (Has_Compatible_Type): Do not consider interpretations hidden by

10022 types declared in the declarative part of a nested package body or in
10023 the proper body of a stub.

10025 of the same dispatch table slot to renamed primitives.
10026 (Make_Select_Specific_Data_Table): Handle private types.

10028 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10029 output of implicit importation and exportation.
10030 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10031 first formal of the thunk is always associated with the controlling
10032 type. In addition perform the following code cleanup: remove formal
10033 Thunk_Alias which is no longer required, cleanup evaluation of the
10034 the controlling type, and update the documentation.
10035 Replace occurrence of Default_Prim_Op_Count by
10036 Max_Predef_Prims. Addition of compile-time check to verify
10037 that the value of Max_Predef_Prims is correct.
10038 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10039 (Make_DT): Add parameter to indicate when type has been frozen by an
10040 object declaration, for diagnostic purposes.
10041 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10042 construction of statically allocated dispatch tables.
10043 (Make_DT): In case of library-level tagged types export the declaration
10044 of the primary tag. Remove generation of tags (now done by Make_Tags).
10045 Additional modifications to handle non-static generation of dispatch
10046 tables. Take care of building tables for asynchronous interface types
10047 (Make_Tags): New subprogram that generates the entities associated with
10048 the primary and secondary tags of Typ and fills the contents of Access_
10049 Disp_Table. In case of library-level tagged types imports the forward
10050 declaration of the primary tag that will be declared later by Make_DT.
10051 (Expand_Interface_Conversion): In case of access types to interfaces
10052 replace an itype declaration by an explicit type declaration to avoid
10053 problems associated with the scope of such itype in transient blocks.

10056 Ed Schonberg <schonberg@adacore.com>
10057 Javier Miranda <miranda@adacore.com>
10059 * exp_util.ads, exp_util.adb:
10060 This patch replaces a number of occurrences of explicit tests for N_Null
10061 with calls to Known_Null. This improves tracking of null values, since
10062 Known_Null also catches null constants, and variables currently known to
10063 be null, so we get better tracking.
10064 (Ensure_Defined): create an itype reference only in the scope of the
10066 (Side_Effect_Free): A selected component of an access type that
10067 denotes a component with a rep clause must be treated as not
10068 side-effect free, because if it is part of a linked structure its
10069 value may be affected by a renaming.
10070 (Expand_Subtype_From_Expr): For limited objects initialized with build
10071 in place function calls, do nothing; otherwise we prematurely introduce
10072 an N_Reference node in the expression initializing the object, which
10073 breaks the circuitry that detects and adds the additional arguments to
10074 the called function. Bug found working in the new patch for statically
10075 allocated dispatch tables.
10076 (Is_Library_Level_Tagged_Type): New subprogram.
10077 (Remove_Side_Effects): If the expression of an elementary type is an
10078 operator treat as a function call.
10079 (Make_Literal_Range): If the index type of the array is not integer, use
10080 attributes properly to compute the constraint on the resulting aggregate
10083 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10084 class-wide type whose base type is an incomplete private type, leave
10085 class-wide type unfrozen so that freeze nodes can be generated
10086 properly at a later point.
10087 (Freeze_Entity, array case): Handle case of pragma Pack and component
10088 size attributre clause for same array.

10148 source dirs are not known.
10149 (Check_Ada_Name): Allow all identifiers that are not reserved words

10732 Thomas Quinot <quinot@adacore.com>
10734 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
10735 derived type with interface progenitors use the analyzed formal as the
10736 parent of the actual, to create renamings for all the inherited
10737 operations in Derive_Subprograms.
10738 (Collect_Previous_Instances): new procedure within of
10739 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
10740 unit being loaded, to ensure that the generation of global symbols is
10741 consistent in different compilation modes.
10742 (Is_Tagged_Ancestor): New function testing the ancestor relation that
10743 takes progenitor types into account.
10744 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
10745 traversing over the primitives of the formal and actual types to locate
10746 any abstract subprograms of the actual type that correspond to a
10747 nonabstract subprogram of the formal type's ancestor type(s), and issue
10748 an error if such is found.
10749 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
10750 Instantiate_Package_Body, Instantiate_Subprogram_Body):
10751 Remove bogus guard around calls to Inherit_Context.
10752 (Reset_Entity): If the entity is the selector of a selected component
10753 that denotes a named number, propagate constant-folding to the generic
10754 template only if the named number is global to the generic unit.
10755 (Set_Instance_Env): Only reset the compilation switches when compiling
10756 a predefined or internal unit.
10758 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10760 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
10761 parameter to determine whether operation applies to the prefix.
10762 (Complete_Object_Operation): If actual has an access type and
10763 controlling formal is not an in_parameter, reject the actual if it is
10764 an access_to_constant type.
10765 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
10766 type, the candidate operations are found in the scope of declaration of
10767 the type, because the type has no primitive subprograms.
10768 (Analyze_Selected_Component): If prefix is class-wide, and root type is
10769 a private extension, only examine visible components before trying to
10770 analyze as a prefixed call.
10771 Change Entity_List to Type_To_Use, for better readability.
10772 (Has_Fixed_Op): Use base type when checking whether the type of an

10780 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
10781 formal At_Any_Place indicating, when True, that we want to test for
10782 availability of the stream attribute at any place (as opposed to the
10783 current visibility context only).
10784 (Missing_Read_Write_Attributes): A stream attribute is missing for the
10785 purpose of enforcing E.2.2(8) only if it is not available at any place.
10786 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
10787 when checking the legality of an extension aggregate in a preelaborable
10788 package. Treat the literal null as a valid default expression in a
10789 component declaration for a type with preelaborable initialization.
10790 A limited interface is a legal progenitor for the designated type of a
10791 remote access to class-wide type.

10804 (Find_Selected_Component, Has_Components): Handle properly non-limited
10805 views that are themselves incomplete types.
10806 Handle interfaces visible through limited-with clauses.
10807 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
10808 subprogram generic actual for which we have generated a renaming.
10809 Warn when the renaming introduces a homonym of
10810 the renamed entity, and the renamed entity is directly visible.

10819 the allocator is not a coextension.
10820 (Resolve): Skip an interpretation hidden by an abstract operator only
10821 when the type of the interpretation matches that of the context.
10822 (Resolve): When looping through all possible interpretations of a node,
10823 do not consider those that are hidden by abstract operators.
10824 (Resolve_Actuals): When verifying that an access to class-wide object
10825 is an actual for a controlling formal, ignore anonymous access to
10826 subprograms whose return type is an access to class_wide type.
10827 (Resolve_Slice): If the prefix of the slice is a selected component
10828 whose type depends on discriminants, build its actual subtype before
10829 applying range checks on the bounds of the slice.
10830 (Valid_Conversion): In an instance or inlined body, compare root types,
10831 to prevent anomalies between private and public views.
10832 (Resolve): Improve error message for ambiguous fixed multiplication
10833 expressions that involve universal_fixed multiplying operations.

10838 * exp_ch9.adb (Build_Protected_Entry): Propagate the original source
10839 location to allow the correct generation of errors in case of

10850 typecode parameters for a union (in a variant record), remove
10851 extraneous layer of Any wrapping for member label.
10852 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
10853 elabration statements, register the package with the name server
10854 at the beginning, not at the end, of the elaboration statements so
10855 that they can create remote access to subprogram values that designate
10856 remote subprograms from the package.
10858 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
10860 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
10861 values to compute the number of seconds since the Unix Epoc in order to

12018 (Write_Entity_Flags): Deal with Universal_Aliasing flag.
12019 (Check_Nested_Access): New procedure.
12020 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
12021 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
12022 (Related_Interface): New attribute. Present in dispatch table pointer
12023 components of records. Set to point to the entity of the corresponding
12025 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
12026 (Original_Access_Type): Remove, not needed.
12027 (Root_Type): Handle properly subtypes of class-wide-types.
12030 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12031 class-wide types visible through limited-with clauses.
12032 (Try_Primitive_Operation): When examining all primitive operations of a
12033 tagged type, do not consider subprograms labeled as hidden unless they
12034 belong to a private generic type with a tagged parent.
12035 (Try_Object_Operation): Extensive rewriting, to handle properly various
12036 overloading cases, when several ancestors may have class-wide operations
12037 that are possible candidates, and when the overloaded functions return
12038 array types and have defaulted parameters so that the call may be
12039 interpreted as an indexing.
12040 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12041 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12042 successive actuals before analyzing the call itself.
12043 (Try_Primitive_Operation): A primitive operation is compatible with the
12044 prefix if the prefix has a synchronized type and the type of the formal
12045 is its corresponding record, as can be the case when the primitive
12046 operation is declared outside of the body of the type.
12047 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12048 perform homonym traversal, looking for class-wide operation matches
12049 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12050 access parameters are now restricted to anonymous access types.
12051 (Mark_Allocator): An allocator with a discriminant association parent is
12053 (Try_One_Prefix_Interpretation): If the type of the object is
12054 incomplete, as can be happen when it is a limited view obtained through
12055 a limited_with_clause, the selected component is not part of a prefixed
12057 (Complete_Object_Operation): Diagnose properly an object that is not
12058 aliased when the corresponding controlling formal is an access
12060 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12061 ambiguous calls in prefixed notation, where two primitives differ only
12062 in that the controlling argument of one is an access parameter.
12064 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12065 whether a function that returns an unconstrained type can be inlined.
12066 (Process_Formals): Diagnose properly the illegal use of an incomplete
12067 type in the profile of an access_to_subprogram declaration.
12068 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12069 operations are attached to the corresponding record.
12070 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12071 When processing a primitive of a concurrent type which implements an
12072 interface change the type of all controlling formals to that of the
12073 corresponding record type.
12074 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12075 to determine the tagged type to which a primitive belongs.
12076 (Check_Conventions): Capture condition to ignore a primitive operation
12077 (which is shared between the loop in Check_Conventions and the one in
12078 Check_Convention) in a new local function Skip_Check.
12079 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12080 confusion with Check_Conventions' own Prim_Op local variable.
12081 (Create_Extra_Formals): Test for a tagged result type rather than a
12082 controlling result when determining whether to add a BIP_Alloc_Form
12083 formal and a BIP_Final_List formal to the function.
12084 (Check_Conformance); For parameters that are anonymous access types,
12085 subtype conformance requires that the not null and the constant
12086 indicators must match
12087 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12088 to retrieve the appropriate type when processing a concurrent type
12089 declared within a generic. Minor comment reformatting. Change invocation
12090 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12092 (Analyze_Subprogram_Body): If the return type of a function is an
12093 anonymous access to the limited view of a class-wide type, and the
12094 non-limited view of the type is available, update the type of the
12095 function so that code can be generated.
12096 (Process_Formals): In case of access-subtype itype whose designated
12097 type is also an itype (situation that happens now with access to
12098 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12099 attribute to avoid backend problems.
12100 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12101 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12102 anonymous types' designated types are same before testing
12103 Subtypes_Statically_Match.
12104 (Create_Extra_Formals): Test for a named access parameter that is a
12105 controlling formal as an additional condition for adding an
12106 accessibility level formal. This can occur in the subp type created for
12107 dispatching calls in Expand_Dispatching_Call, and allows calling
12108 Create_Extra_Formals from that procedure rather than special-casing the
12109 extra formals there.
12110 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12111 when the function has a controlling result.
12112 (Check_Returns): Add much more knowledge of the optimization of local
12113 raise statements to gotos, to retain proper warnings in this case.
12114 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12115 nodes when looking for last statement.
12117 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12118 class-wide types visible through limited with clauses.
12119 (Add_One_Interp): If the operands are anonymous access types, the
12120 predefined operator on universal_access is immediately visibles
12121 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12122 other anonymous access types.
12123 (Disambiguate): Take into account CIL convention.
12124 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12126 2007-06-06 Robert Dewar <dewar@adacore.com>
12128 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
12129 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
12130 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
12131 Fix lower bound of tables.
12134 * nlists.adb: Ditto.
12135 (Prev_Node, Next_Node): Change index type to Int so that it properly
12136 covers the range First_Node_Id - 1 up.
12138 2007-06-06 Javier Miranda <miranda@adacore.com>
12139 Ed Schonberg <schonberg@adacore.com>
12140 Bob Duff <duff@adacore.com>
12141 Hristian Kirtchev <kirtchev@adacore.com>
12143 * exp_aggr.ads, exp_aggr.adb:
12144 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12145 in extension aggregates.
12146 (Flatten): Other conditions being met, an aggregate is static if the
12147 low bound given by component associations is different from the low
12148 bound of the base index type.
12149 (Packed_Array_Aggregate_Handled): If the component type is itself a
12150 packed array or record, the front-end must expand into assignments.
12151 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12152 Init_Pr, instead of Ancestor_Is_Expression.
12153 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12154 coextension chain root, either generate a list controller or use the
12155 already existing one.
12156 (Static_Array_Aggregate): New procedure to construct a positional
12157 aggregate that can be handled by the backend, when all bounds and
12158 components are compile-time known constants.
12159 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12160 types covering interface types into assignments.
12161 (Replace_Type): move to Build_Record_Aggr_Code.
12162 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12163 interface type, convert to the definite type of the aggregate itself,
12164 so that needed components are visible.
12165 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12166 components and the context is an extended return statement do not
12167 create a transient block for it, to prevent premature finalization
12168 before the return is executed.
12169 (Gen_Assign): Do not generate a call to deep adjust routine if the
12170 component type is itself an array of controlled (sub)-components
12171 initialized with an inner aggregate.
12172 (Component_Check): New name for Static_Check. This name is now more
12173 appropriate, and documentation is added which was missing.
12174 (Component_Check): Add test for bit aligned component value
12175 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12176 Tagged_Comps, name is more appropriate given added function below.
12177 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
12179 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
12180 Javier Miranda <miranda@adacore.com>
12181 Robert Dewar <dewar@adacore.com>
12183 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12184 Terminated: Add unchecked type conversion from System.Address to
12185 System.Tasking.Task_Id when calling the predefined primitive
12187 Disable new Ada 05 accessibility check for JVM.NET targets, which
12188 cannot be implemented in a practical way.
12189 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12190 the sources always references the tag of the actual object. Therefore,
12191 if 'Tag is applied in the sources to class-wide interface objects we
12192 generate code that displaces "this" to reference the base of the object.
12193 (Expand_N_Attribute_Reference, case Size): Return specified size if
12194 known to front end.
12195 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12196 has code that displaces the pointer of the object to manage interface
12197 types. However this code must not be executed when the prefix is a
12198 subprogram. This bug caused the wrong expansion of the internally
12199 generated assignment that fills the dispatch table when the primitive
12200 is a function returning a class-wide interface type.
12201 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12202 Set_Attribute_Name for Name_Unaligned_Valid.
12204 2007-06-06 Ed Schonberg <schonberg@adacore.com>
12205 Gary Dismukes <dismukes@adacore.com>
12207 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12208 If the initialization is the equivalent aggregate of the initialization
12209 procedure of the type, do not remove it.
12210 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12211 initialized to null from having their expression reset to empty and
12212 note this exception in the comment.

12216 Ed Schonberg <schonberg@adacore.com>
12217 Gary Dismukes <dismukes@adacore.com>
12219 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
12220 Add "with" and "use" clauses for Sem_Attr.
12221 (Expand_Current_Value): Do not replace occurences of attribute
12222 references where the prefix must be a simple name.
12224 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
12225 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
12226 Attribute_Requires_Simple_Name_Prefix.
12227 (Name_Modifies_Prefix): Body of new function.
12228 (Requires_Simple_Name_Prefix): Body of new function.
12229 (Resolve_Attribute, case Access): Improve error message for case of
12230 mismatched conventions.
12231 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
12233 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12234 constrained subtype for a nominal unconstrained type, use its base type
12235 to check for conformance with the context.
12236 (Resolve_Attribute): Remove test of the access type being associated
12237 with a return statement from condition for performing accessibility
12238 checks on access attributes, since this case is now captured by
12239 Is_Local_Anonymous_Access.
12240 (Analyze_Access_Attribute): Set Address_Taken on entity
12241 (Analyze_Attribute, case Address): Set Address_Taken on entity
12242 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
12243 validating an access attribute whose prefix is a current instance.
12244 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
12245 applied to dispatching operations, if freezing is required then we set
12246 the attribute Has_Delayed_Freeze in the prefix's entity.
12247 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
12248 current scope if access of local subprogram taken
12249 (Analyze_Access_Attribute): Check legality of self-reference even if the
12250 expression comes from source, as when a single component association in
12251 an aggregate has a box association.
12252 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
12253 the prefix if it is a protected operation and the attribute is
12254 Unrestricted_Access.
12255 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
12256 reference to the base type of the context, to force a constraint check
12257 when the context is an access subtype with an explicit constraint.
12258 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
12259 node is rewritten as an interface conversion. leave unanalyzed after
12260 resolution, to ensure that type checking against the context will take

12264 Javier Miranda <miranda@adacore.com>
12265 Robert Dewar <dewar@adacore.com>
12267 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
12268 wrapper when the full view of the controlling type of an inherited
12269 function that dispatches on result implements interfaces.
12270 (Expand_N_Object_Declaration): In cases where the type of the
12271 declaration is anonymous access, create finalization list for it.
12272 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
12273 if the object has no explicit initialization, to match description of
12274 functionality of pragam Persistent_BSS.
12275 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
12276 new function to build static aggregates, to replace initialization call
12277 when static initialization is desired.
12278 (Freeze_Type): Generate a list controller for an access type whenever
12279 its designated type has controlled anonymous access discriminants.
12280 (Build_Equivalent_Aggregate): New procedure to compute a static
12281 aggregate to be used as default initialization for composite types,
12282 instead of a generating a call to the initialization procedure for the
12284 (Build_Initialization_Call): When available, replace a call to the
12285 initialization procedure with a copy of the equivalent static aggregate
12287 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
12288 declarations for objects of a class-wide interface type, rather than
12289 just identifiers, to prevent visibility problems.
12290 (Expand_N_Object_Declaration): When expanding the declaration for an
12291 object of a class-wide interface type, preserve the homonym chain of
12292 the original entity before exchanging it with that of the generated
12293 renaming declaration.
12294 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
12295 active, because there is no way to handle the exception.
12296 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
12297 to do a minimum decoration of the Access_Disp_Table list.
12298 (Expand_Record_Controller): Avoid the addition of the controller between
12299 the component containing the tag of a secondary dispatch table and its
12300 adjacent component that stores the offset to the base of the object.
12301 This latter component is only generated when the parent type has
12302 discriminants ---documented in Add_Interface_Tag_Components).
12303 (Apply_Array_Size_Check): Removed, no longer needed.
12304 (Expand_N_Full_Type_Declaration): If the type has anonymous access
12305 components, create a Master_Entity for it only if it contains tasks.
12306 (Build_Init_Procedure): Suppress the tag assignment compiling under
12308 (Freeze_Record_Type): Remove code associated with creation of dispatch
12310 (Init_Secondary_Tags): Update type of actuals when generating calls to
12311 Ada.Tags.Set_Offset_To_Top
12312 (Stream_Operation_OK): Disable use of streams compiling under no
12314 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
12315 if Has_Init_Expression set.
12316 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
12317 Register_Primitive, which provides the same functionality.
12318 (Requires_Init_Proc): Return false in case of interface types.
12319 (Add_Secondary_Tables): Use the new attribute Related_Interface to
12321 (Predefined_Primitive_Freeze): Do not assume that an internal entity
12322 is always associated with a predefined primitive because the internal
12323 entities associated with interface types are not predefined primitives.
12324 Therefore, the call to Is_Internal is replaced by a call to the
12325 function Is_Predefined_Dispatching_Operation.
12326 (Make_Eq_If): When generating the list of comparisons for the
12327 components of a given variant, omit the controller component that is
12328 present if the variant has controlled components.
12330 2007-06-06 Javier Miranda <miranda@adacore.com>
12331 Hristian Kirtchev <kirtchev@adacore.com>
12332 Bob Duff <duff@adacore.com>
12334 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
12335 handle the creation of finalization lists and calls for nested
12336 coextensions when the root of the chains is part of a return statement.
12337 (Inside_A_Return_Statement): New function inside Complete_Coextension_
12339 (Expand_Record_Equality): Skip components that are interface types.
12340 (Displace_Allocator_Pointer): Add missing support for interface subtypes
12341 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
12342 with Rewrite_Coextension. Change the condition for detecting coextension
12344 (Is_Local_Access_Discriminant): Removed.
12345 (Rewrite_Coextension): New routine which rewrites a static coextension
12346 as a temporary and uses its unrestricted access in the construction of
12348 (Complete_Coextension_Finalization): New routine. Generate finalization
12349 attachment calls to all delayed coextensions.
12350 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
12351 the allocator is not a coextension itself and has delayed coextensions.
12352 If the current allocator is controlled, but also a coextension, delay
12353 the generation of the finalization attachment call.
12354 Rename local variable "Node" to "Nod" in order to avoid confusion with
12356 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
12357 limited types that are not inherently limited. Such an allocator is
12358 illegal, but is generated by the expander for a return statement, to
12359 copy the result onto the secondary stack. This is the only case where a
12360 limited object can be copied. Generate code to displace the pointer
12361 to the object if the qualified expression is a class-wide interface
12362 object. Such displacement was missing and hence the copy of the object
12364 (Apply_Accessibility_Check): Handle allocated objects initialized in
12366 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
12367 and Expand_Allocator_Expression. Allocating class-wide interface objects
12368 this routine displaces the pointer to the allocated object to reference
12369 the component referencing the corresponding secondary dispatch table.
12370 Expand_Allocator_Expression): Add missing support to allocate class-wide
12371 interface objects initialized with a qualified expression.
12372 (Get_Allocator_Final_List): Test for an anonymous access type that is a
12373 function result type, and use the finalization list associated with the
12374 function scope in that case (such an anonymous type should not be
12375 treated like an access parameter's type).
12377 2007-06-06 Ed Schonberg <schonberg@adacore.com>
12378 Gary Dismukes <dismukes@adacore.com>
12379 Javier Miranda <miranda@adacore.com>
12381 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
12382 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
12383 required exception handler.
12384 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
12385 properly the case of a function whose return type is a limited
12386 class-wide interface type. Modify the code of the accessibility
12387 check to handle class-wide interface objects. In this case we need to
12388 displace "this" to reference the primary dispatch table to get access
12389 to the TSD of the object (to evaluate its accessibility level).
12390 (Expand_N_Extended_Return_Statement): Test for a tagged result type
12391 rather than a controlling result as one of the conditions for
12392 generating tests of the implicit BIP_Alloc_Form formal. The
12393 initialization assignment is also handled according to whether the
12394 result is tagged instead of controlling.
12395 In the case where the init assignment is inserted in the "then" part of
12396 the allocation conditional, rewrite the target to be a dereference of
12397 the implicit BIP_Object_Access formal.
12398 If the returned value is unconstrained and created on the secondary
12399 stack, mark the enclosing block and function so that the secondary
12400 stack is not reclaimed on return.
12401 Treat returns from functions with controlling results similarly to
12402 returns from functions with unconstrained result subtypes.
12403 If the object returned is unconstrained, and an allocator must be
12404 created for it, analyze the allocator once the block for the extended
12405 return is installed, to ensure that finalizable components
12406 of the expression use the proper finalization list. Guard the call to
12407 Move_Final_List with a check that there is something to finalize.
12408 (Make_Tag_Ctrl_Assignment): Use "old" handling
12409 of controlled type assignment for virtual machines, since new code uses
12410 unsupported features (such as direct access to bytes in memory).
12412 2007-06-06 Gary Dismukes <dismukes@adacore.com>
12413 Ed Schonberg <schonberg@adacore.com>
12415 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
12416 accessibility actual, check for the case of an aliased object that has
12417 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
12418 we fall into processing for the attribute rather than the name of the
12420 (Expand_Inline_Call): If an actual is a literal, and the corresponding
12421 formal has its address taken in the body, create a temporary to capture
12422 value. If the return type is a limited interface, do not treat the
12423 return value as Controlled.
12424 (Is_In_Place_Function): If the return type is a limited interface,
12425 treat as returning in place. The actual returned object may not always
12426 be limited, but the caller has to assume that it is returned in place.
12427 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
12428 context of an allocator, use the correct finalization chain (that is,
12429 the chain belonging to the access type, rather than the chain belonging
12430 to the current scope).
12431 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
12432 result type rather than a controlling result as a precondition for
12433 adding an allocation form actual to a build-in-place call.
12434 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
12435 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
12436 primitive in the dispatch tables. This work is now done by Make_DT when
12437 the type is frozen.
12438 (Register_Predefined_DT_Entry): Removed.
12439 (Add_Return): If end label is not present, use sloc of last statement
12440 for generated return statement in procedure, for better gdb behavior

12447 the allocation form parameter if the result subtype is constrained,
12448 except when the function has a controlling result.
12449 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
12450 rather than Is_Controlled and Has_Controlled_Component, since we want to
12451 include class-wide result types in this treatment. Also test for a
12452 controlling result, since that also requires passing a finalization
12454 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
12455 even when the result subtype is constrained, to handle calls involving
12456 controlling results.
12457 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
12458 is now called even when the result subtype is constrained, to handle
12459 calls involving controlling results.
12460 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
12461 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
12462 now performs the test).
12463 (Make_Build_In_Place_Call_In_Object_Declaration):
12464 Add_Alloc_Form_Actual_* is now called even when the result subtype is
12465 constrained, to handle calls involving controlling results.
12466 (Add_Return): Accomodate rewritten pattern from local raise to goto
12467 transformation, so that we still recognize an transfer statement
12468 and do the right thing here in that case.
12469 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
12470 and end of subprogram code.
12471 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
12472 support for primitives that are functions (without formals) with a
12473 controlling result.

12475 type, it is not an actual for a formal derived type, and there is no
12476 operation to inherit from the formal.

12485 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
12486 Raise_From_Controlled_Operation is available, use a call to that
12487 subprogram instead of a plain "raise Program_Error" node to raise
12488 Program_Error if an exception is propagated from an Adjust or Finalize
12490 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
12491 appears in the optional statement list of a triggering alternative, the
12492 scope actions can be inserted directly there, and not in the list that
12493 includes the asynchronous select itself.
12495 2007-06-06 Ed Schonberg <schonberg@adacore.com>
12496 Robert Dewar <dewar@adacore.com>

12523 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
12524 functionality when the backend is generating code.
12525 Otherwise any serious error
12526 reported by the backend calling the frontend routine Error_Msg
12527 changes the Compilation_Mode to Check_Semantics, disables the
12528 functionality of this routine and causes the generation of
12529 spureous additional errors.
12531 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
12532 debugging information now generated by the compiler for fat-pointer
12534 Document the contents of DW_AT_producer in the GNAT Vendor extensions to

12546 stream attributes of the designated type of an RACW, as they are not
12547 dispatching primitive operations.

12568 deallocation of class-wide interface objects.
12569 (Expand_Dispatching_Constructor_Call): Take into account that if the
12570 result of the dispatching constructor is an interface type, the
12571 function returns a class-wide interface type; otherwise the returned
12572 object would be actual. The frontend previously accepted returning
12573 interface types because Expand_Interface_Actuals silently performed
12574 the management of the returned type "as if" it were a class-wide
12576 (Expand_Dispatching_Constructor_Call): Replace call to
12577 Make_DT_Access_Action by direct call to Make_Function_Call.

12611 Gary Dismukes <dismukes@adacore.com>
12613 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a

12639 considererd limited.
12640 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
12641 should be declared as limited and that it will be considererd limited.

12666 object of a limited type can be initialized with a call to a function
12667 that returns in place. If the limited type has unknown discriminants,
12668 and the underlying type is a constrained composite type, build an actual
12669 subtype from the function call, as is done for private types.
12670 (Side_Effect_Free): An expression that is the renaming of an object or
12671 whose prefix is the renaming of a object, is not side-effect free
12672 because it may be assigned through the renaming and its value must be
12673 captured in a temporary.
12674 (Has_Controlled_Coextensions): New routine.
12675 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
12676 as is done for other limited types.

12726 Add new warning for renaming of function return objects
12728 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size

12733 * opt.ads: Add new warning for renaming of function return objects
12734 (Generating_Code): New boolean variable used to indicate that the

12751 Also reject attempt to rename function return object in Ada 83 mode.
12752 (Attribute_Renaming): In case of tagged types, add the body of the
12753 generated function to the freezing actions of the type.
12754 (Find_Type): A protected type is visible right after the reserved word
12755 "is" is encountered in its type declaration. Set the entity and type

12783 (Deallocate, Dereference): Send error messages to the proper stream
12784 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
12785 documented. Previous code would send it to the current output file
12786 defined in GNAT.IO, which might not be stdout
12787 (Is_Valid): Adjust comment to mention that a positive reply means that
12788 Header_Of may be used to retrieve the allocation header associated with
12789 the subprogram Storage address argument. Return False early if this

12808 Correct error message when invocation of the linker fails
12809 Add explicit size clause for the C imported variables
12810 Object_List_File_Supported and Using_GNU_Linker to emphasize that
12811 we expect char size.
12812 Read target parameters earlier, since this is needed to set
12813 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
12816 2007-06-06 Vincent Celier <celier@adacore.com>
12819 Add 3 spaces before the default project directory when displaying
12820 the project search path.

13377 occurs on an allocator node. Add processing and cleanup for static
13379 (Valid_Conversion): If the operand type is the limited view of a
13380 class-wide type, use the non-limited view is available to determine
13381 legality of operation.
13382 (Ambiguous_Character): move to spec, for use elsewhere.
13383 (Ambiguous_Character): Handle Wide_Wide_Character in Ada 2005 mode
13384 (Resolve_Range): Diagnose properly an ambiguous range whose bounds are
13385 character literals.
13386 (Resolve_Arithmetic_Op): Call Activate_Division_Check instead of setting
13387 Do_Division_Check flag explicitly.
13388 (Resolve_Actuals): If the actual is of a synchronized type, and the
13389 formal is of the corresponding record type, this is a call to a
13390 primitive operation of the type, that is declared outside of the type;
13391 the actual must be unchecked-converted to the type of the actual
13392 (Resolve_Call): Kill all current values for any subprogram call if
13393 flag Suppress_Value_Tracking_On_Call is set.
13394 (Resolve_Type_Conversion): Generate error message the the operand
13395 or target of interface conversions come from a limited view.
13396 (Check_Infinite_Recursion): Ignore generated calls
13397 (Check_Allocator_Discrim_Accessibility): New procedure for checking
13398 that an expression that constrains an access discriminant in an
13399 allocator does not denote an object with a deeper level than the
13400 allocator's access type.
13401 (Resolve_Allocator): In the case of an allocator initialized by an
13402 aggregate of a discriminated type, check that associations for any
13403 access discriminants satisfy accessibility requirements by calling
13404 Check_Allocator_Discrim_Accessibility.

13409 (Resolve_Type_Conversion): Add missing support for conversion to
13411 (Resolve_Actuals): Introduce a transient scope around the call if an
13412 actual is a call to a function returning a limited type, because the

13426 both entities. This is required to statically build the dispatch table.
13427 (Declare_Inherited_Private_Subprograms): Rewriten to avoid the need
13428 of calling Set_All_DT_Position to re-evaluate the position of the
13429 entries in the dispatch table. Such reevaluation is not desired if

13461 function's result type to determine the level of the return object's
13463 (Build_Elaboration_Entity): Build name of elaboration entity from the
13464 scope chain of the entity, rather than the unit name of the file name.

13500 (Rmsg_28): Fix description for E.4(18) check.
13501 (Raise_Current_Excep): Call Debug_Raise_Exception just before
13502 propagation starts, to let debuggers know about the event in a reliable
13504 Take the address of E and dereference to make sure it is homed on stack
13505 and prevent the stores from being deleted, necessary for proper
13506 debugger behavior on "break exception" hits.

14298 (Resolve_Call): If the call returns an array, the context imposes the
14299 component type of the array, and the function has one non-defaulted
14300 parameter, rewrite the call as the indexing of a call with a single
14301 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
14303 (Resolve_Actuals): If an actual is an allocator for an access parameter,
14304 the master of the created object is the innermost enclosing statement.
14305 (Remove_Conversions): For a binary operator, check if type of second
14306 formal is numeric, to check if an abstract interpretation is present

14548 attempt to derive from a synchronized tagged type.

14553 that use (a subtype of) the class-wide type of the enclosing type.
14554 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
14555 Derived_Type for Prev formal on call to
14556 Check_Anonymous_Access_Components rather than Empty.
14557 (Make_Incomplete_Type_Declaration): Add test for case where the type has
14558 a record extension in deciding whether to create a class-wide type,

14639 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
14640 when -gnatg is not specified.

14690 same scope level as the allocator's type. The check is guaranteed to
14691 succeed in that case, even when the expression originates from a
14692 parameter of the containing subprogram.
14693 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
14694 under No_Dispatching_Calls restriction. During the semantic analysis
14695 we already notified such violation.
14696 (Tagged_Membership): Constant folding. There is no need to check
14697 the tag at run-time if the type of the right operand is non
14698 class-wide abstract.
14699 Replace call to Is_Ancestor by call to Is_Parent
14700 to support concurrent types with interface types.
14701 (Expand_N_Allocator): Add an assertion associated with the generation
14703 (Expand_N_Slice): Do not enable range check to nodes associated
14704 with the frontend expansion of the dispatch table.

14706 Expand_N_Allocator.
14707 (Tagged_Membership): Replace generation of call to the run-time
14708 subprogram CW_Membership by call to Build_CW_Membership.
14709 (Expand_Allocator_Expression): Replace generation of call to the
14710 run-time subprogram Get_Access_Level by call to Build_Get_Access_Level.
14712 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
14713 initialize most the TSD components by means of an aggregate.
14714 Modify the declaration of the object containing the TSD
14715 because we now expand code that has a higher level of abstraction.
14716 The TSD has a discriminant containing the Inheritance Depth Level,
14717 value that is used in the membership test but also to fix the size
14718 of the table of ancestors.
14719 (Expand_Interface_Conversion): Insert function body at the closest place
14720 to the conversion expression, to prevent access-before-elaboration
14721 errors in the backend.
14722 Code improved to reduce the size of the dispatch table if
14723 compiling under restriction No_Dispatching_Calls plus code cleanup.
14724 Code reorganization plus removal of calls to Set_Num_Prim_Ops
14725 (Make_Secondary_DT): Remove call to Set_Num_Prim_Ops.
14726 (Expand_Dispatching_Call): Minor code reorganization plus addition of
14727 code to return immediately if compiling under No_Dispatching_Calls
14729 (Set_All_DT_Position): Remove code associated with the old CPP pragmas.
14730 CPP_Virtual and CPP_Vtable are no longer supported.
14731 (Expand_Interface_Conversion): Add missing support for interface type
14733 (Expand_Interface_Actuals): Replace calls to Is_Ancestor by calls to
14734 Is_Parent to support concurrent types with interfaces.

14736 (Make_Secondary_DT): Modified to support concurrent record types.
14737 (Set_All_DT_Position): Modified to support concurrent record types.
14738 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entries associated
14739 with Get_External_Tag, Inherit_TSD, Set_External_Tag.
14740 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entry associated
14741 with CW_Membership.
14742 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entries associated
14743 with Get_Access_Level, Get_Predefined_Prim_Op_Address,
14744 Get_Prim_Op_Address Get_RC_Offset, Get_Remotely_Callable, Inherit_DT,
14745 Set_Access_Level, Set_Expanded_Name, Set_Predefined_Prim_Op_Address,
14746 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
14747 (Expand_Dispatching_Call): Replace generation of call to the run-time
14748 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
14749 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
14751 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
14752 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
14753 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
14754 Build_Set_Prim_Op_Address.
14755 (Get_Remotely_Callable): Subprogram removed.
14756 (Init_Predefined_Interface_Primitives): Replace generation of call to
14757 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
14760 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
14761 First (Parameter_Associations ()) with the call to First_Actual that
14762 returns an actual parameter expression for both named and positional
14765 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
14766 check violation of restriction No_Dispatching_Calls.
14767 (Check_Controlling_Type): A formal of a tagged incomplete type is a
14768 controlling argument.
14770 * exp_util.ads, exp_util.adb (Type_May_Have_Bit_Aligned_Components): Use
14771 First/Next_Component_Or_Discriminant
14772 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
14773 (Find_Implemented_Interface): Removed. All the calls to this subprogram
14774 specify Any_Limited_Interface, and this functionality is already
14775 provided by the function Has_Abstract_Interfaces.
14776 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
14777 support concurrent types implementing interfaces.
14778 (Find_Implemented_Interface): Removed. All the calls to this subprogram
14779 specify kind Any_Limited_Interface, and this functionality is already
14780 provided by the function Has_Abstract_Interfaces.
14781 (Remove_Side_Effects): replace Controlled_Type by
14782 CW_Or_Controlled_Type whenever the issue is related to
14783 using or not the secondary stack.
14785 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
14786 P_Interface_Type_Definition to fulfill the new interface (the formal
14787 Is_Synchronized is no longer required).
14789 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
14790 Update dependencies.
14792 * exp_atag.ads, exp_atag.adb: New file
14794 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14795 Bob Duff <duff@adacore.com>
14796 Cyrille Comar <comar@adacore.com>
14798 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
14799 anonymous, use finalization list of enclosing dynamic scope.
14800 (Expand_N_Package_Declaration): For a library package declaration
14801 without a corresponding body, generate RACW subprogram bodies in the
14802 spec (just as we do for the task activation call).
14803 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
14804 Is_Abstract_Type. Make sure these are called only when appropriate.
14805 Remove all code for DSP option
14806 (CW_Or_Controlled_Type): new subprogram.
14808 2007-04-06 Eric Botcazou <botcazou@adacore.com>
14809 Ed Schonberg <schonberg@adacore.com>
14810 Gary Dismukes <dismukes@adacore.com>
14812 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
14813 parameter. If it is set to true, return a result capped according to
14814 the global upper bound for the index of an entry family.
14815 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
14816 (Build_Find_Body_Index): Adjust for above change.
14817 (Entry_Index_Expression): Likewise.
14818 (Is_Potentially_Large_Family): New function extracted from...
14819 (Collect_Entry_Families): ...here. Call it to detect whether the family
14820 is potentially large.
14821 (Build_Entry_Count_Expression): If the family is potentially large, call
14822 Family_Size with 'Cap' set to true.
14823 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
14824 a protected version of an operation declared in the private part of
14825 a protected object, because they may be invoked through a callback.
14826 (Set_Privals): If the type of a private component is an anonymous access
14827 type, do not create a new itype for each protected body.
14828 If the body of a protected operation creates
14829 controlled types (including allocators for class-widetypes), the
14830 body of the corresponding protected subprogram must include a
14832 (Build_Activation_Chain_Entity): Build the chain entity for extended
14834 (Type_Conformant_Parameters): Use common predicate Conforming_Types
14835 to determine whether operation overrides an inherited primitive.
14836 (Build_Wrapper_Spec): Add code to examine the parents while looking
14837 for a possible overriding candidate.
14838 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
14839 hold an actual parameter value since its initialization is separated
14840 from the the declaration. Prevents errors on null-excluding access
14843 2007-04-06 Thomas Quinot <quinot@adacore.com>
14844 Pablo Oliveira <oliveira@adacore.com>
14846 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
14847 Do an Unchecked_Conversion to handle the passage from the Underlying
14848 Type to the Base Type when calling Build_To_Any_Call and
14849 Build_From_Any_Call.
14850 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
14851 E_Constant, depending upon Variable formal.
14852 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14853 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
14854 parameter that requires an extra constrained parameter, declare
14855 temporary for actual as a variable, not a constant.
14856 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
14857 the unit being compiled is the one that contains the stub type.
14858 Change primitive operation name for the RACW associated with a RAS
14859 from Call to _Call so it cannot clash with any legal identifier.
14860 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
14862 (Append_RACW_Bodies): New subprogram.
14863 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
14864 Add_Receiving_Stubs_To_Declarations functions.
14865 When expanding a package body, this list correspond to the
14866 statements in the HSS at the end of the pacakge.
14867 When expanding a package spec, this list correspond to the
14869 (Add_Receiving_Stubs_To_Declarations): Append the function
14870 registering the receiving stubs at the end of the 'Stmts' list.
14871 (RCI_Package_Locator): Pass the new Version generic formal when
14872 instantiating a RCI_Locator package.
14873 (Build_From_Any_Function): To compute the High bound for an
14874 unconstrained array actual, we add the Low bound with the length.
14875 Thus we must convert the low bound and the length to an appropriate
14876 type before doing the sum.
14877 (Build_Subprogram_Receiving_Stubs, PolyORB):
14878 * Retrieve the extra formals parameters at the
14879 end of the parameter stream.
14880 * Use Move_Any_Value to write back out parameters
14881 after executing the request as it is more efficient
14882 than Copy_Any_Value.
14883 * Build the any containing Extra Formals with the
14884 appropriate typecode.
14885 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
14886 empty Component_List.
14887 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
14888 the tree the declaration for an object that serves as actual parameter
14889 in server-side stubs.
14890 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14891 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
14892 Use Build_Actual_Object_Declaration to prepare the actuals.

14894 Extra Constrained Parameters.
14895 (Build_General_Calling_Stubs): Set the parameter type to boolean for
14896 Extra Constrained parameters.
14897 (Build_To_Any_Function, Build_From_Any_Function,
14898 Built_TypeCode_Function): When Typ is implicit, call the correct
14899 function with the first not implicit parent type.
14900 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
14901 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
14902 typecode from the Etype. Therefore we retrieve the correct typecode
14903 with a call to Get_Any_Type.
14904 (Copy_Specification): Do controlling formal type substitution based on
14905 Is_Controlling_Formal flag, instead of caller-provided object type.
14906 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
14907 a RACW primitive operation, we might get a subprogram declaration for an
14908 ancestor of the RACW designated type (not for the designated type
14909 itself), in the case where this operation is inherited. In this case we
14910 have no easy means of determining the original tagged type for which
14911 the primitive was declared, so instead we now rely on
14912 Copy_Specification to use the Is_Controlling_Formal flag to determine
14913 which formals require type substitution.

14916 Ed Schonberg <schonberg@adacore.com>
14918 * exp_intr.adb (Expand_Exception_Call): Calls to subprograms in
14919 GNAT.Current_Exception are not allowed if pragma Restrictions
14920 (No_Exception_Propagation) is set and in any case make the associated
14921 handler unsuitable as a target for a local raise statement.
14922 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
14923 run-time subprogram CW_Membership by call to Build_CW_Membership.
14924 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
14925 by a function call, a temporary must be created before expanding the
14926 Constructor_Call itself, to prevent out-of-order elaboration in the
14927 back-end when stack checking is enabled..
14929 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14931 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
14932 result are the bounds of the left operand, not the right.
14934 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14937 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use
14938 discriminant defaults.

14943 Bob Duff <duff@adacore.com>
14945 * sem_aggr.adb (Resolve_Record_Aggregate): In semantics-only mode treat
14946 an association with a box as providing a value even though the
14947 initialization procedure for the type is not available.

14949 box corresponds to a component of the type.
14950 (Resolve_Record_Aggregate): Split Is_Abstract flag into
14951 Is_Abstract_Subprogram and Is_Abstract_Type.

14962 * g-alleve.ads (Low Level Vector type definitions): Map each to the
14963 associated vector view instead of all to the unsigned char view.

14966 offering facilities for all the Vector/View conversion routines
14967 implemented by this unit.

15048 * i-cstrea.ads: (fopen): Add encoding parameter.
15050 Change reference from a-sysdep.c to sysdep.c in comment.
15051 Update copyright notice.
15052 This set of patch add support for the encoding form parameter.
15054 * mingw32.h (S2WSU): New macro to convert from a string to a
15055 wide-string using the UTF-8 encoding. The S2WS macro supports now only
15056 standard 8bits encoding.
15057 (WS2SU): As above but converting from wide-sring to string.
15058 This is needed as it is necessary to have access to both versions in the
15059 runtime for the form parameter encoding support.
15060 This set of patch add support for the encoding form parameter.
15061 (S2WS): Improve implementation to handle cases where the filename is not
15062 UTF-8 encoded. In this case we default to using the current code page
15063 for the conversion.
15065 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
15066 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

15072 encoding. This is needed for the Reset routine (freopen low level-call).
15074 * s-fileio.adb (Open): Decode encoding form parameter and set the
15075 corresponding encoding value into AFCB structure.
15076 (Reset): Pass the encoding value to freopen.
15077 (Close): Move the call to Lock_Task to the beginning of the procedure.

15110 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
15111 __gnat_adjust_context_for_raise.
15112 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
15113 implementation of floating point operations as native x86 targets.
15114 So the FPU should be initialized in the same way using finit. Fix
15115 floating point operations accuracy issues.
15116 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
15117 member in struct sigaction, so as to avoid warning for incompatible

15135 * lib-xref.ads, lib-xref.adb:
15136 Modify the loop that collects type references, to include interface
15137 types that the type implements. List each of these interfaces when
15138 building the entry for the type.
15139 (Generate_Definition): Initialize component Def and Typ of new entry
15140 in table Xrefs, to avoid to have these components unitialized.
15141 (Output_References): Split Is_Abstract flag into
15142 Is_Abstract_Subprogram and Is_Abstract_Type.
15143 (Generate_Reference): Add barrier to do not generate the warning
15144 associated with Ada 2005 entities with entities generated by the

15184 2007-04-06 Robert Dewar <dewar@adacore.com>
15186 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
15187 it no longer destroys the contents of Name_Buffer or Name_Len and
15188 non-standard and invalid names are handled better.
15189 (Get_Decoded_Name_String): Improve performance by using
15190 Name_Has_No_Encodings flag in the name table.
15191 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
15192 Used for debugging printouts.

15195 Javier Miranda <miranda@adacore.com>
15196 Bob Duff <duff@adacore.com>
15198 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
15199 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15200 there is no need to generate always a record_definition_node in case
15201 of synchronized interface types.
15202 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
15203 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
15204 illegal in Ada 95, in cases where it is legal. Change the warnings to
15205 errors in other cases. Don't give the error unless the "not null"
15206 parses properly. Correct the source position at which the error occurs.
15207 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
15208 P_Null_Exclusion, to suppress "not null" warnings.

15258 Library_Builder, Local_Config_File, Objects_Path, Objects_Path_File,
15259 Run_Path_Option, Toolchain_Version.
15260 Entry for pragma Unreferenced_Objects
15262 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
15263 switches, without repetition of "eD". Make sure that last character of
15264 -gnatep= switch is not taken as -gnat switch character.
15265 Complete rewrite of circuit for handling saving compilation options
15266 Occasioned by need to support dot switchs for -gnatw, but cleans up

15284 the default project path, initially done during elaboration of the
15286 If the prefix returned by Sdefault is null, get the prefix from a call
15287 to Executable_Prefix_Path.
15288 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
15291 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
15292 canonical directory name to open the directory from which files are
15294 (Record_Other_Sources): Idem.
15295 (Locate_Directory): Add the possibility to create automatically missing
15296 directories when Setup_Projects is True.
15297 Call Locate_Directory so that the directory will be created when
15298 Setup_Projects is True, for object dir, library dir, library ALI dir,
15299 library source copy dir and exec dir.
15301 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
15304 2007-04-06 Robert Dewar <dewar@adacore.com>

15319 Next_Component_Or_Discriminant.
15321 * style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
15324 * stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch

15339 full word is no longer compared twice.
15341 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15343 * sem_ch10.adb (Install_Limited_Context_Clauses.
15344 Expand_Limited_With_Clause): Use a new copy of selector name in the
15345 call to Make_With_Clause. This fixes the tree structure for ASIS
15346 purposes. Nothing is changed in the compiler behaviour.
15347 (Process_Body_Clauses): Handle properly use clauses whose prefix is
15348 a package renaming.
15349 (Install_Limited_With_Clauses): Do not install non-limited view when it
15350 is still incomplete.
15352 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15353 Gary Dismukes <dismukes@adacore.com>
15355 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
15356 when capturing size information, instead of base type, which for a
15357 formal array type will be the unconstrained type.
15358 (Analyze_Formal_Object_Declaration): Add check for illegal default
15359 expressions for a formal in object of a limited type.
15360 (Instantiate_Object): Ditto.
15361 (Check_Formal_Package_Instance): Skip entities that are formal objects,
15362 because they were defaulted in the formal package and no check applies
15364 (Check_Formal_Package_Instance): Extend conformance check to other
15365 discrete types beyond Integer.
15366 (Process_Default): Copy directly the unmatched formal. A generic copy
15367 has already been performed in Analyze_Formal_Package.
15368 (Analyze_Associations): If a formal subprogram has no match, check for
15369 partial parametrization before looking for a default, to prevent
15371 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
15372 not set the instantiation environment before analyzing the actuals.
15373 Fixes regression on 8515-003 with implementation of AI-133.
15374 Set_Instance_Env checks whether the generic unit is a predefined
15375 unit, in which case the instance must be analyzed with the latest Ada
15376 mode. This setting must take place after analysis of the actuals,
15377 because the actuals must be analyzed and frozen in the Ada mode extant
15378 outside of the current instantiation.
15379 (Save_Env, Restore_Env): Preserve and restore the configuration
15380 parameters so that predefined units can be compiled in the proper Ada
15382 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
15383 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
15384 and Is_Abstract_Type.
15385 (Analyze_Formal_Package): For better error recovery, Add exception
15386 handler to catch Instantion_Error, which can be raised in
15387 Analyze_Associations
15389 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15390 Bob Duff <duff@adacore.com>
15391 Gary Dismukes <dismukes@adacore.com>
15393 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
15394 prefix type is a discriminated subtype of the type of the formal.
15395 (Analyze_Allocator): Collect all coextensions regardless of the context.
15396 Whether they can be allocated statically is determined in exp_ch4.
15397 (Analyze_Selected_Component): If the prefix is a limited view and the
15398 non-limited view is available, use the non-limited one.
15399 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
15400 therefore illegal), suggest a qualified expression rather than a type
15401 conversion, because a type conversion would be illegal in this context.
15402 (Anayze_Allocator): Trace recursively all nested allocators so that all
15403 coextensions are on the corresponding list for the root. Do no mark
15404 coextensions if the root allocator is within a declaration for a stack-
15405 allocated object, because the access discriminants will be allocated on
15407 (Analyze_Call): Remove restriction on calls to limited functions for the
15408 cases of generic actuals for formal objects, defaults for formal objects
15409 and defaults for record components.
15410 (Analyze_Allocator): Before analysis, chain coextensions on the proper
15411 element list. Their expansion is delayed until the enclosing allocator
15412 is processed and its finalization list constructed.
15413 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
15414 for an operation with the given name among the primitive operations of
15415 the corresponding record type.
15416 (Analyze_Selected_Component): If the prefix is a task type that
15417 implements an interface, and there is no entry with the given name,
15418 check whether there is another primitive operation (e.g. a function)
15420 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
15421 properly the indexing of a function call written in prefix form, where
15422 the function returns an array type, and all parameters of the function
15423 except the first have defaults.
15424 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
15425 the original operands, rather than relocating them, for efficiency and
15426 to work properly when an operand is overloaded.
15427 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
15428 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
15429 (Analyze_Selected_Component): If the prefix is a private extension, only
15430 scan the visible components, not those of the full view.
15431 (Try_Primitive_Operation): If the operation is a procedure, collect all
15432 possible interpretations, as for a function, because in the presence of
15433 classwide parameters several primitive operations of the type can match
15434 the given arguments.
15436 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15437 Robert Dewar <dewar@adacore.com>
15439 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
15440 tag-indeterminate call to an abstract function, when the left-hand side
15442 (Analyze_Loop_Statement): Improve detection of infinite loops
15444 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15445 Thomas Quinot <quinot@adacore.com>
15447 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
15448 out of Analyze_Package_Declaration, because processing must be applied
15449 to package bodies as well, for deferred constants completed by pragmas.
15450 (Analyze_Package_Declaration): When the package declaration being
15451 analyzed does not require an explicit body, call Check_Completion.
15452 (May_Need_Implicit_Body): An implicit body is required when a package
15453 spec contains the declaration of a remote access-to-classwide type.
15454 (Analyze_Package_Body): If the package contains RACWs, append the
15455 pending subprogram bodies generated by exp_dist at the end of the body.
15456 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
15457 Is_Abstract_Subprogram and Is_Abstract_Type.
15458 (Preserve_Full_Attributes): The full entity list is not an attribute
15459 that must be preserved from full to partial view.
15461 * sem_dist.adb (Add_RAS_Dereference_TSS):
15462 Change primitive name to _Call so it cannot clash with any legal
15463 identifier, and be special-cased in Check_Completion.
15464 Mark the full view of the designated type for the RACW associated with
15465 a RAS as Comes_From_Source to get proper view switching when installing
15466 private declarations.
15467 Provite a placeholder nested package body along with the nested spec
15468 to have a place for Append_RACW_Bodies to generate the calling stubs
15469 and stream attributes.
15471 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15472 Robert Dewar <dewar@adacore.com>
15474 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
15475 that is a limited view, check the non-limited view if available.
15476 (Undefined): Refine error message for missing with of Text_IO
15477 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
15478 to distinguish real missing with cases.
15479 Fix format of all missing with messages
15480 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
15481 renaming as body when renamed entity is abstract.
15483 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15484 Javier Miranda <miranda@adacore.com>
15486 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
15487 predicate recursive, to handle complex expressions on literals whose
15488 spurious ambiguity comes from the abstract interpretation of some
15490 (Interface_Present_In_Ancestor): Add support to concurrent record
15492 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
15493 Is_Abstract_Subprogram and Is_Abstract_Type.
15495 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15496 Javier Miranda <miranda@adacore.com>
15498 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
15499 dereference of a local object R created as a reference to another
15500 object O, use the access level of O.
15501 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
15502 rather than local Same_Formal_Type, to check whether protected operation
15503 overrides an inherited one.
15504 (Same_Formal_Type): New predicate, used when matching signatures of
15505 overriding synchronized operations, to handle the case when a formal
15506 has a type that is a generic actual.
15507 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
15508 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
15509 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
15510 syntactic ambiguities involving indexing of function calls that return
15512 (Abstract_Interface_List): New subprogram that returns the list of
15513 abstract interfaces associated with a concurrent type or a
15514 concurrent record type.
15515 (Interface_Present_In_Parent): New subprogram used to check if a
15516 given type or some of its parents implement a given interface.
15517 (Collect_Abstract_Interfaces): Add support for concurrent types
15518 with interface types.
15519 (Has_Abstract_Interfaces): Add support for concurrent types with
15521 (Is_Parent): New subprogram that determines whether E1 is a parent
15522 of E2. For a concurrent type its parent is the first element of its
15523 list of interface types; for other types this function provides the
15524 same result than Is_Ancestor.
15525 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
15526 (Collect_Synchronized_Interfaces): Removed because the subprogram
15527 Collect_Abstract_Interfaces provides this functionality.
15528 (Collect_Abstract_Interfaces): Minor update to give support to
15529 concurrent types and thus avoid undesired code duplication.
15530 (Get_Subprogram_Entity): Handle entry calls.
15531 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
15533 (Enter_Name): Do not give -gnatwh hiding warning for record component
15534 entities, they never result in hiding.

15537 Robert Dewar <dewar@adacore.com>
15539 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,
15540 to chain nested components that are allocators for access discriminants
15541 of the enclosing object.
15542 Add N_Push and N_Pop nodes
15543 New field Exception_Label added
15544 (Local_Raise_Statements): New field in N_Exception_Handler_Node
15545 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node
15546 (Is_Coextension): New flag for allocators, to mark allocators that
15547 correspond to access discriminants of dynamically allocated objects.
15548 (N_Block_Statement): Document the fact that the corresponding entity
15549 can be an E_Return_Statement.
15550 (Is_Coextension): New flag for allocators.
15551 Remove all code for DSP option
15553 * sprint.ads, sprint.adb: Display basic information for class_wide
15554 subtypes. Add handling of N_Push and N_Pop nodes
15556 2007-04-06 Arnaud Charlet <charlet@adacore.com>
15558 * s-tpobop.adb (Exceptional_Complete_Entry_Body): Undefer abortion
15559 before propagating exception.
15561 2007-04-06 Olivier Hainque <hainque@adacore.com>
15563 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
15564 an address always within the call instruction from a return address.
15566 2007-04-06 Olivier Hainque <hainque@adacore.com>
15567 Eric Botcazou <botcazou@adacore.com>
15569 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
15570 expression with a COMPOUND_EXPR including the call instead of emitting
15571 the call directly here.
15572 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
15573 high bound is constant and the slice is empty. Tidy.
15574 (tree_transform, case N_Op_Not): Handle properly the case where the
15575 operation applies to a private type whose full view is a modular type.
15576 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
15577 Address_Clause, use the associated Expression as the GNAT tree
15578 representing the choice value to ensure the corresponding GCC tree is
15579 of the proper kind.
15580 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
15581 instead of just the operands, as the base GCC stabilize_reference does.
15582 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
15583 requested; otherwise fail.
15584 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
15586 2007-04-06 Thomas Quinot <quinot@adacore.com>
15588 * uintp.ads, uintp.adb (UI_Div_Rem): New subprogram, extending previous
15589 implementation of UI_Div.

15864 anonymous access types.
15865 (Valid_Conversion): For a conversion to a numeric type occurring in an
15866 instance or inlined body, no need to check that the operand type is

16572 the parent part is a build-in-place function call, generate assignments.
16573 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
16574 are build-in-place function calls.
16575 (Replace_Self_Reference): New subsidiary of
16576 Make_OK_Assignment_Statement, to replace an access attribute that is a
16577 self-reference into an access to the appropriate component of the
16578 target object. Generalizes previous mechanism to handle self-references
16579 nested at any level.
16580 (Is_Self_Referential_Init): Remove, not needed.
16581 (Is_Self_Referential_Init): New predicate to simplify handling of self
16582 referential components in record aggregates.

16584 check for presence of entity before checking for self-reference.
16585 (Has_Default_Init_Comps): Return True if a component association is a
16586 self-reference to the enclosing type, which can only come from a
16587 default initialization.
16588 (Make_OK_Assignment_Statement): If the expression is of the form
16589 Typ'Acc, where Acc is an access attribute, the expression comes from a
16590 default initialized self-referential component.
16591 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
16592 that has been derived from several abstract interfaces we must also
16593 initialize the tags of the secondary dispatch tables.

16598 Robert Dewar <dewar@adacore.com>
16601 (Expand_Access_To_Protected_Op): If the context indicates that an access
16602 to a local operation may be transfered outside of the object, create an
16603 access to the wrapper operation that must be used in an external call.
16604 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
16605 target, pass the Valid attribute applied to a floating-point prefix on
16606 to the back end without expansion.
16607 (Storage_Size): Use the new run-time function Storage_Size to retrieve
16608 the allocated storage when it is specified by a per-object expression.
16609 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
16610 Nothing to do here, the attribute has been rewritten during semantic

16614 (Find_Fat_Info): Handle case of universal real
16615 (Expand_Access_To_Protected_Op): Fix use of access to protected

16619 into a fat pointer.
16620 (Is_Constrained_Aliased_View): New predicate to help determine whether a
16621 subcomponent's enclosing variable is aliased with a constrained subtype.
16622 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
16623 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
16624 an aliased prefix must be known to be constrained in order to use True
16625 for the attribute value, and now it's possible for some aliased views
16626 to be unconstrained.
16628 2006-10-31 Robert Dewar <dewar@adacore.com>
16630 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
16631 (Expand_Entity_Reference): Correct error of not handling subprogram
16632 formals in current_value processing.
16634 2006-10-31 Javier Miranda <miranda@adacore.com>

16637 Gary Dismukes <dismukes@adacore.com>
16639 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
16640 register in the final list objects containing class-wide interfaces;
16641 otherwise we incorrectly register the tag of the interface in the final
16643 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
16644 generate the wrapper if the parent primitive is abstract. This is
16645 required to report the correct error message.
16646 (Expand_N_Subtype_Indication): Do validity checks on range
16647 (Clean_Task_Names): If an initialization procedure includes a call to
16648 initialize a task (sub)component, indicate that the procedure will use
16649 the secondary stack.
16650 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
16651 compatibility for interfacing with CPP by default.
16652 (Expand_N_Object_Declaration): Only build an Adjust call when the
16653 object's type is a nonlimited controlled type.
16654 * exp_ch3.adb: Add with and use of Exp_Ch6.
16655 (Expand_N_Object_Declaration): Check for object initialization that is a
16656 call to build-in-place function and apply Make_Build_In_Place_Call_In_
16657 Object_Declaration to the call.
16658 (Freeze_Type): When the designated type of an RACW was not frozen at the
16659 point where the RACW was declared, validate the primitive operations
16660 with respect to E.2.2(14) when it finally is frozen.
16661 (Build_Initialization_Call,Expand_Record_Controller): Rename
16662 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
16663 return-by-reference has no meaning in Ada 2005.
16664 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
16665 to register tag of the immediate ancestor interfaces in the
16666 run-time structure.

16668 initialization of extension aggregates with abstract interfaces.
16669 (Build_Master_Renaming): Make public, for use by function declarations
16670 whose return type is an anonymous access type.
16671 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
16672 Insert_List_Before_And_Analyze after the generation of the specs
16673 associated with null procedures.
16674 (Expand_Tagged_Root): Update documentation in its specification.
16675 (Init_Secondary_Tags): Update documentation.
16676 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
16677 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
16678 then generate code to inherit the contents of the dispatch table
16679 directly from the ancestor.
16680 (Expand_Record_Controller): Insert controller component after tags of
16681 implemented interfaces.
16682 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
16683 create null procedure overridings when null procedures are inherited
16685 (Make_Null_Procedure_Specs): New procedure to generate null procedure
16686 declarations for overriding null primitives inherited from interfaces.
16687 (Is_Null_Interface_Procedure): New function in
16688 Make_Null_Procedure_Specs.
16689 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
16690 immediate ancestor of a tagged type is an abstract interface type we
16691 must generate the specification of the predefined primitives associated
16692 with controlled types (because the dispatch table of the ancestor is
16693 null and hence these entries cannot be inherited). This is required to
16694 elaborate well the dispatch table.

16702 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
16704 (Expand_N_In): Do validity checks on range
16705 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
16706 (Expand_N_Allocator): For "new T", if the object is constrained by
16707 discriminant defaults, allocate the right amount of memory, rather than
16708 the maximum for type T.
16709 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
16710 when the allocator is initialized by a build-in-place call, since the
16711 allocator is already rewritten as a reference to the function result,
16712 and this prevents an unwanted duplication of the function call.
16713 Add with and use of Exp_Ch6.
16714 (Expand_Allocator_Expresssion): Check for an allocator whose expression
16715 is a call to build-in-place function and apply
16716 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
16717 untagged designated types).
16718 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
16719 optimization if source or target is biased.
16720 (Expand_N_Allocator): Add comments for case of an allocator within a
16721 function that returns an anonymous access type designating tasks.
16722 (Expand_N_Allocator): apply discriminant checks for access
16723 discriminants of anonymous access types (AI-402, AI-416)

16732 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
16733 (Expand_N_Assignment_Statement): Call
16734 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
16735 build-in-place function call. Currently, this can happen only for
16736 assignments that come from aggregates.
16737 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
16738 in order to alleviate the upward compatibility introduced by AI-318.
16739 (Expand_N_Extended_Return_Statement): Add support for handling the
16740 return object as a build-in-place result.
16741 (Expand_Non_Function_Return): Implement simple return statements nested
16742 within an extended return.
16743 (Enable_New_Return_Processing): Turn on the new processing of return
16745 (Expand_Non_Function_Return): For a return within an extended return,
16746 don't raise Program_Error, because Sem_Ch6 now gives a warning.
16747 (Expand_N_Extended_Return_Statement): Implement AI-318
16748 (Expand_Simple_Function_Return): Ditto.
16749 (Expand_N_If_Statement): Handle new -gnatwt warning

16751 (Expand_N_Assignment): Handle assignment to the Priority attribute of
16752 a protected object.
16753 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
16754 validity checking of assignments to elementary record components.
16755 (Expand_N_Return_Statement): return Class Wide types on the secondary
16756 stack independantly of their controlled status since with HIE runtimes,
16757 class wide types are not potentially controlled anymore.
16759 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
16762 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
16763 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
16764 it expects a block, procedure, or task. The return statement will get
16765 turned into a block, and Expand_Cleanup_Actions will happen then.
16767 2006-10-31 Robert Dewar <dewar@adacore.com>
16768 Ed Schonberg <schonberg@adacore.com>
16769 Bob Duff <duff@adacore.com>
16770 Gary Dismukes <dismukes@adacore.com>
16772 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
16774 (Expand_Inlined_Call): Tagged types are by-reference types, and
16775 therefore should be replaced by a renaming declaration in the expanded
16776 body, as is done for limited types.
16777 (Expand_Call): If this is a call to a function with dispatching access
16778 result, propagate tag from context.
16779 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
16781 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
16782 build-in-place when the right-hand side of an assignment is a
16783 build-in-place function call.
16784 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
16785 of the explicit dereference of the allocator to the result subtype of
16786 the build-in-place function. This is needed to satisfy type checking
16787 in cases where the caller's return object is created by an allocator for
16788 a class-wide access type and the type named in the allocator is a
16790 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
16791 conversion of the reference to the declared object to the result subtype
16792 of the build-in-place function. This is needed to satisfy type checking
16793 in cases where the declared object has a class-wide type. Also, in the
16794 class-wide case, change the type of the object entity to the specific
16795 result subtype of the function, to avoid passing a class-wide object
16796 without explicit initialization to the back end.
16797 (Register_Interface_DT_Entry): Moved outside the body of
16798 Freeze_Subprogram because this routine is now public; it is called from
16799 Check_Dispatching_Overriding to handle late overriding of abstract
16800 interface primitives.
16801 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
16802 adding an implicit access actual on a call to a build-in-place function.
16803 (Expand_Actuals): Test for an actual parameter that is a call to a
16804 build-in-place function and apply
16805 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
16806 (Is_Build_In_Place_Function): New function to determine whether an
16807 entity is a function whose calls should be handled as build-in-place.
16808 (Is_Build_In_Place_Function_Call): New function to determine whether an
16809 expression is a function call that should handled as build-in-place.
16810 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
16811 calls to build-in-place functions as the initialization of an allocator.
16812 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
16813 handling calls to build-in-place functions in contexts that do not
16814 involve init of a separate object (for example, actuals of subprogram
16816 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
16817 handling calls to build-in-place functions as the initialization of an
16818 object declaration.

16820 instantiation of Traverse_Body to avoid unreferenced warning.
16821 (Check_Overriding_Inherited_Interfaces): Removed.
16822 (Register_Interface_DT_Entry): Code cleanup.
16823 (Register_Predefined_DT_Entry): Code cleanup.
16824 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
16825 inlined statements if within a transient scope.
16826 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
16827 formal parameters with occurrences of actuals in inlined body, establish
16828 visibility on the proper view of the actual's subtype for the body's
16830 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
16831 compatibility mode and we have an imported CPP subprogram because
16832 for now we assume that imported CPP primitives correspond with
16833 objects whose constructor is in the CPP side (and therefore we
16834 don't need to generate code to register them in the dispatch table).
16835 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
16836 aligned selected component.
16837 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
16838 the actual of an in-mode parameter is a type conversion.
16839 (Expand_Actuals): If the call does not come from source and the actual
16840 is potentially misaligned, let gigi handle it rather than rejecting the
16841 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
16842 Class Wide types as returning by reference independantly of their
16843 controlled status since with HIE runtimes class wide types are not
16844 potentially controlled anymore.
16846 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16848 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
16849 references that are private components of the protected object.

16851 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
16852 instantiation to deal with warnings.

16859 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
16860 initialization of Homonym_Len.
16861 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
16862 names from fully qualified name. Fixes problem of duplicate
16863 external names differing only in the presence of such a block name.
16865 2006-10-31 Thomas Quinot <quinot@adacore.com>
16866 Pablo Oliveira <oliveira@adacore.com>
16868 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
16869 subprogram Ids, even if they are not yet assigned.
16870 (Build_Subprogram_Id): It is now this function that will take care of
16871 calling Assign_Subprogram_Ids if necessary.
16872 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
16873 should be done only once they are assigned.
16874 (Build_From_Any_Function, case of tagged types): Add missing call to

16877 type for an RACW type.
16878 (Add_RACW_Features): When processing an RACW declaration for which the
16879 designated type is already frozen, enforce E.2.2(14) rules immediately.
16880 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
16881 special reordering of controlling formals.
16883 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
16884 associated stub type for an RACW type.
16886 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16888 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
16889 fixed-point operations in an integer context, i.e. as operands of a
16890 conversion to an integer type, indicate that result must be rounded.
16892 2006-10-31 Robert Dewar <dewar@adacore.com>
16894 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
16895 cases, pass the encoding method, since it is now required by the run
16898 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
16899 assumption that Str'First = 1.
16900 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
16901 it on to the Value_Wide_Wide_Character call.
16902 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
16903 properly handles a string of the form quote-encoded_wide_char-quote.
16905 * s-wchcnv.adb: Minor reformatting
16907 2006-10-31 Javier Miranda <miranda@adacore.com>

16915 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
16916 Machine_Attribute pragma internally to implement the user pragma.
16917 Add processing for pragma Interface so that it is now completely
16918 equivalent to pragma Import.
16920 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
16921 so that it can be applied to all entities, including record components
16922 and enumeration literals.
16923 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
16924 priority ranges are correct, verify compatibility against task
16925 dispatching and locking policies, and if everything is correct an entry
16926 is added to the table containing priority specific dispatching entries
16927 for this compilation unit.
16928 (Delay_Config_Pragma_Analyze): Delay processing
16929 Priority_Specific_Dispatching pragmas because when processing the
16930 pragma we need to access run-time data, such as the range of
16931 System.Any_Priority.
16932 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
16933 Allow pragma Unreferenced as a context item
16934 Add pragma Preelaborable_Initialization
16935 (Analyze_Pragma, case Interface): Interface is extended so that it is
16936 now syntactically and semantically equivalent to Import.
16937 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
16938 insertion characters.
16939 Add handling for Pragma_Wide_Character_Encoding
16940 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
16941 never supercedes a real restriction, and that a real restriction
16942 always supercedes a warning.
16943 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
16946 2006-10-31 Bob Duff <duff@adacore.com>
16947 Ed Schonberg <schonberg@adacore.com>
16948 Robert Dewar <dewar@adacore.com>
16950 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
16951 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
16952 Is_Inherently_Limited_Type, because return-by-reference has no meaning
16954 (Find_Node_To_Be_Wrapped): Use new method of determining the result
16955 type of the function containing a return statement, because the
16956 Return_Type field was removed. We now use the Return_Applies_To field.
16958 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
16959 (Build_Task_Image_Decl): If procedure is not called from an
16960 initialization procedure, indicate that function that builds task name
16961 uses the sec. stack. Otherwise the enclosing initialization procedure
16962 will carry the indication.
16963 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
16964 N_Object_Declaration instead.
16965 (Kill_Dead_Code): New interface to implement -gnatwt warning for
16966 conditional dead code killed, and change implementation accordingly.
16967 (Insert_Actions): Add N_Return_Object_Declaration case.
16968 Correct comment to mention N_Extension_Aggregate node.
16969 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
16970 attempts to save information for global variables which cannot be
16972 (Get_Current_Value_Condition): Handle conditions the other way round
16973 (constant on left). Also handle right operand of AND and AND THEN
16974 (Set_Current_Value_Condition): Corresponding changes
16975 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
16976 (Get_Current_Value_Condition): Handle simple boolean operands
16977 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
16978 (Get_Current_Value_Condition): If the variable reference is within an
16979 if-statement, does not appear in the list of then_statments, and does
16980 not come from source, treat it as being at unknown location.
16981 (Get_Current_Value_Condition): Enhance to allow while statements to be
16982 processed as well as if statements.
16983 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
16985 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
16986 of loop. This is safe now that we fixed Kill_Current_Values.
16987 (OK_To_Do_Constant_Replacement): Check whether current scope is
16988 Standard, before examining outer scopes.
16990 2006-10-31 Vincent Celier <celier@adacore.com>
16992 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
16993 When True, apply VMS treatment to children of packages A, G, I and S.
16996 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
16998 2006-10-31 Robert Dewar <dewar@adacore.com>
16999 Ed Schonberg <schonberg@adacore.com>
17001 * freeze.adb: Add handling of Last_Assignment field
17002 (Warn_Overlay): Supply missing continuation marks in error msgs
17003 (Freeze_Entity): Add check for Preelaborable_Initialization
17005 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17007 * g-expect.adb: Add Warnings (Off) to prevent new warning
17009 * lib-xref.adb: Add handling of Last_Assignment field
17010 (Generate_Reference): Centralize handling of pragma Obsolescent here
17011 (Generate_Reference): Accept an implicit reference generated for a
17012 default in an instance.
17013 (Generate_Reference): Accept a reference for a node that is not in the
17014 main unit, if it is the generic body corresponding to an subprogram
17017 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17019 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17021 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17023 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17024 use clauses, to avoid messages on packages used to qualify, and also
17025 to avoid messages from obsolescent units.
17026 (Warn_On_Useless_Assignments): Don't generate messages for imported
17027 and exported variables.
17028 (Warn_On_Useless_Assignments): New procedure
17029 (Output_Obsolescent_Entity_Warnings): New procedure
17030 (Check_Code_Statement): New procedure
17032 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
17033 Change name Is_Ada_2005 to Is_Ada_2005_Only
17034 (Last_Assignment): New field for useless assignment warning
17036 2006-10-31 Olivier Hainque <hainque@adacore.com>
17038 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17039 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17041 2006-10-31 Bob Duff <duff@adacore.com>
17042 Robert Dewar <dewar@adacore.com>
17043 Ed Schonberg <schonberg@adacore.com>
17045 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17046 Ada 95 mode, because it violates the new rules for AI-318.
17048 * g-awk.ads: Use overloaded subprograms in every case where we used to
17049 have a default of Current_Session. This makes the code closer to be
17050 correct for both Ada 95 and 2005.
17052 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17053 code, relying on the fact that the compiler generates a warning
17054 instead of an error in -gnatg mode.
17056 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17057 E_Return_Statement entity kind.
17058 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17060 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17061 report an error if the reserved word abstract has been previously found.
17062 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17064 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17065 parenthesized range attribute usage
17066 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17068 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17069 in the syntax for extended_return_statement. This is not in the latest
17070 RM, but the ARG is expected to issue an AI allowing this.
17071 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17072 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17073 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17074 P_Return_Statement): Parse the new syntax for extended_return_statement.
17076 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17077 Output_End_Missing): Add error-recovery code for the new
17078 extended_return_statement syntax; that is, the new E_Return entry on
17081 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17082 limited to nonlimited, because otherwise we violate the new Ada 2005
17083 rules about returning limited types in function Create_AST_Handler in
17086 * sem.adb (Analyze): Add cases for new node kinds
17087 N_Extended_Return_Statement and N_Return_Object_Declaration.
17089 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17090 type is in the same category as type of context before applying check,
17091 to prevent anomalies in instantiations.
17092 (Resolve_Aggregate): Remove test for limited components in aggregates.
17093 It's unnecessary in Ada 95, because if it has limited components, then
17094 it must be limited. It's wrong in Ada 2005, because limited aggregates
17096 (Resolve_Record_Aggregate): Move check for limited types later, because
17097 OK_For_Limited_Init requires its argument to have been resolved.
17098 (Get_Value): When copying the component default expression for a
17099 defaulted association in an aggregate, use the sloc of the aggregate
17100 and not that of the original expression, to prevent spurious
17101 elaboration errors, when the expression includes function calls.
17102 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17103 were missing. We also didn't handle qualified expressions. Now also
17104 allow function calls. Use new common routine OK_For_Limited_Init.
17105 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17106 with space can upper case letter).
17108 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17109 Has_Static_Discriminants flag
17110 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17111 type with discriminants.
17112 (Process_Range_Expr_In_Decl): Do validity checks on range
17113 (Build_Discriminant_Constraints): Use updated form of
17114 Denotes_Discriminant.
17115 (Process_Subtype): If the subtype is a private subtype whose full view
17116 is a concurrent subtype, introduce an itype reference to prevent scope
17118 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17119 Record_Type_Declaration): The functionality of the subprograms
17120 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17121 is now performed by a single routine.
17122 (Build_Derived_Record_Type): If the type definition includes an explicit
17123 indication of limitedness, then the type must be marked as limited here
17124 to ensure that any access discriminants will not be treated as having
17125 a local anonymous access type.
17126 (Check_Abstract_Overriding): Issue a detailed error message when an
17127 abstract subprogram was not overridden due to incorrect mode of its
17129 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17130 synchronized private extension declarations. Verify that the ancestor is
17131 a limited or synchronized interface or in the generic case, the ancestor
17132 is a tagged limited type or synchronized interface and all progenitors
17133 are either limited or synchronized interfaces.
17134 Derived_Type_Declaration): Check for presence of private extension when
17135 dealing with synchronized formal derived types.
17136 Process_Full_View): Enchance the check done on the usage of "limited" by
17137 testing whether the private view is synchronized.
17138 Verify that a synchronized private view is completed by a protected or
17140 (OK_For_Limited_Init_In_05): New function.
17141 (Analyze_Object_Declaration): Move check for limited types later,
17142 because OK_For_Limited_Init requires its argument to have been resolved.
17143 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17144 in order to alleviate the upward compatibility introduced by AI-318.
17145 (Constrain_Corresponding_Record): If the constraint is for a component
17146 subtype, mark the itype as frozen, to avoid out-of-scope references to
17147 discriminants in the back-end.
17148 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17149 this subprogram against wrong sources.
17150 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17151 discriminant of limited type completed with a protected type, when the
17152 discriminant is used to constrain a private component of the type, and
17153 expansion is disabled.
17154 (Find_Type_Of_Object): Do not treat a return subtype that is an
17155 anonymous subtype as a local_anonymous_type, because its accessibility
17156 level is the return type of the enclosing function.
17157 (Check_Initialization): In -gnatg mode, turn the error "cannot
17158 initialize entities of limited type" into a warning.
17159 (OK_For_Limited_Init): Return true for generated nodes, since it
17160 sometimes violates the legality rules.
17161 (Make_Incomplete_Declaration): If the type for which an incomplete
17162 declaration is created happens to be the currently visible entity,
17163 preserve the homonym chain when removing it from visibility.
17164 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17165 inherited subprograms.
17166 (Access_Definition): If this is an access to function that is the return
17167 type of an access_to_function definition, context is a type declaration
17168 and the scope of the anonymous type is the current one.
17169 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17170 incomplete subtype to the set of private dependents of the original
17172 (Constrain_Discriminated_Type): Emit an error message whenever an
17173 incomplete subtype is being constrained.
17174 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17175 corresponding subtype of the full view of the original incomplete type.
17176 (Check_Incomplete): Properly detect invalid usage of incomplete types
17179 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
17181 * g-catiio.ads, g-catiio.adb (Value): New function.

17187 Integer_Address arithmetic, as in Set_Valid.
17189 2006-10-31 Arnaud Charlet <charlet@adacore.com>
17190 Robert Dewar <dewar@adacore.com>
17192 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
17193 handling executable extension manually and duplicating code.
17195 * make.adb: Implement new -S switch
17196 (Gnatmake): Use new function Osint.Executable_Name instead
17197 of handling executable extension manually.
17199 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
17200 is specified, the executable name ends with this suffix.
17201 Take advantage of Osint.Executable_Name instead of duplicating code.
17203 * switch-m.adb: Recognize new gnatmake -S switch
17205 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
17207 (Get_Target_Parameters): Set Executable_Extension_On_Target if
17210 * makeusg.adb: Add line for gnatmake -S switch
17212 2006-10-31 Vincent Celier <celier@adacore.com>
17214 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17215 call it with -static-libgcc, as there are some platforms, such as
17216 Darwin, where one of these two switches is compulsory to link.
17218 2006-10-31 Vincent Celier <celier@adacore.com>
17220 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17221 instead of ADA_PROJECT_PATH, for the project path.
17222 (Gnatls): When displaying the project path directories, use host dir
17225 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17226 names in the project path, as absolute paths may correspond to
17227 multi-valued VMS logical names.
17229 2006-10-31 Vincent Celier <celier@adacore.com>
17231 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
17232 absolute path name.
17233 (Locate_Regular_File): Ditto
17234 (Change_Dir): Remove, no longer used
17235 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
17236 on Windows. Get it calling Get_Current_Dir.
17237 (OpenVMS): Remove imported boolean, no longer needed.
17238 (Normalize_Pathname)[VMS]: Do not resolve directory names.
17239 (Pid_To_Integer): New function to convert a Process_Id to Integer
17241 2006-10-31 Thomas Quinot <quinot@adacore.com>
17243 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
17244 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
17246 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
17249 2006-10-31 Robert Dewar <dewar@adacore.com>
17251 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
17252 initial letter o as a zero.
17254 2006-10-31 Robert Dewar <dewar@adacore.com>
17256 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
17258 2006-10-31 Robert Dewar <dewar@adacore.com>
17260 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
17262 (Layout_Variant_Record): Retrieve the discriminants from the entity
17263 rather than from the type definition, because in the case of a full
17264 type for a private type we need to take the discriminants from the
17266 (Layout_Component_List): When applying the Max operator to variants with
17267 a nonstatic size, check whether either operand is static and scale that
17268 operand from bits to storage units before applying Max.
17269 (Layout_Type): In VMS, if a C-convention access type has no explicit
17270 size clause (and does not inherit one in the case of a derived type),
17271 then the size is reset to 32 from 64.
17273 2006-10-31 Vincent Celier <celier@adacore.com>
17275 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
17276 its file has already been loaded, according to the unit being loaded,
17277 not to the current value of Multiple_Unit_Index.
17279 2006-10-31 Thomas Quinot <quinot@adacore.com>
17280 Eric Botcazou <ebotcazou@adacore.com>
17281 Arnaud Charlet <charlet@adacore.com>
17283 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
17284 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
17286 (a-except.o): Pass it to the compiler.
17287 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
17288 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
17289 a-calend-mingw.adb version.
17291 * Makefile.rtl: Added s-dsaser.
17292 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
17293 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
17294 Ada.Dispatching.Round_Robin.
17295 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
17297 * Make-lang.in: Remove all references to gt-ada-decl.h.
17298 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
17300 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
17301 Update dependencies.
17303 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
17305 2006-10-31 Vincent Celier <celier@adacore.com>
17307 * mlib-utl.adb (Initialized): Remove, no longer used
17308 (Initialize): Remove, no longer used
17309 (Ar): If Ar_Exec is null, get the location of the archive builder and,
17310 if there is one, the archive indexer. Fail if the archive builder cannot
17312 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
17315 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17317 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
17318 Process_Body_Clauses): If the context of a body includes a use clause
17319 for P.Q then a with_clause for P in the same body is not redundant,
17320 even if the spec also has a with_clause on P.
17321 Add missing continuation mark to error msg
17322 (Build_Limited_Views): A limited view of a type is tagged if its
17323 declaration includes a record extension.
17324 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
17325 node, even if the subunit has errors. This avoids malfunction by
17326 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
17327 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
17328 generation of obsolescent messages for with statements (cannot do
17329 this too early, or we cannot implement avoiding the messages in the
17330 case of obsolescent units withing obsolescent units).
17331 (Install_Siblings): If the with_clause is on a remote descendant of
17332 an ancestor of the current compilation unit, find whether there is
17333 a sibling child unit that is immediately visible.
17334 (Remove_Private_With_Clauses): New procedure, invoked after completing
17335 the analysis of the private part of a nested package, to remove from
17336 visibility the private with_clauses of the enclosing package
17338 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
17339 now centralized in Generate_Reference.
17340 (Install_Limited_Context_Clauses): Remove superfluous error
17341 message associated with unlimited view visible through use
17342 and renamings. In addition, at the point in which the error
17343 is reported, we add the backslash to the text of the error
17344 to ensure that it is reported as a single error message.
17345 Use new // insertion for some continuation messages
17346 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
17347 to create implicit with_clause for parent unit mentioned in original
17348 limited_with_clause.
17349 (Install_Limited_With_Unit): Set entity of parent identifiers if the
17350 unit is a child unit. For ASIS queries.
17351 (Analyze_Subunit): If the subunit appears within a child unit, make all
17352 ancestor child units directly visible again.
17354 2006-10-31 Robert Dewar <dewar@adacore.com>
17356 * par-ch10.adb (P_Context_Clause): Minor error message fix

17364 Add the new actual Abstract_Present to every call to
17365 P_Interface_Type_Definition.
17366 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
17367 a formal object declaration with an access definition or a subtype mark
17368 with a null exclusion.
17369 (P_Generic_Association): Handle association with box, and others_choice
17370 with box, to support Ada 2005 partially parametrized formal packages.

17375 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
17376 (P_Type_Declaration): Remove barrier against the reserved word "limited"
17377 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
17378 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
17379 private extensions.
17380 (P_Type_Declaration): Add the new actual Abstract_Present to every call
17381 to P_Interface_Type_Definition.
17382 (P_Interface_Type_Definition): Addition of one formal to report an error
17383 if the reserved word abstract has been previously found.
17384 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
17385 object renaming declaration with an access definition or subtype mark
17386 with a possible null exclusion.
17388 * par-ch9.adb: Minor error msg fix
17390 * par-load.adb: Add missing continuation mark to error msg

17405 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
17408 2006-10-31 Vincent Celier <celier@adacore.com>
17410 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
17411 on VMS, change "__" to '.' before checking the name.
17412 (Record_Ada_Source): Always add the source file name in the list of
17413 of sources, even if it is not the first time, as it is for another
17415 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
17416 dot, instead of replacing only the first '_'.
17418 * prj-part.adb (Parse): Convert project file path to canonical form
17420 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
17421 extended, the project id of the project extending it is recorded in its
17422 data, even when it has already been processed as an imported project.
17424 2006-10-31 Robert Dewar <dewar@adacore.com>
17426 * repinfo.adb (List_Entities): Don't list entities from renaming
17429 2006-10-31 Arnaud Charlet <charlet@adacore.com>
17430 Robert Dewar <dewar@adacore.com>
17432 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
17433 only a restriction warning is active for the given restriction. This is
17434 desirable because we do not want to modify code in the case where only
17436 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
17437 causes overriding of real restrictions.
17438 Take advantage of new No_Restrictions constant.
17440 * raise.h: (__gnat_set_globals): Change profile.
17442 2006-10-31 Arnaud Charlet <charlet@adacore.com>
17444 * rtsfind.adb: Remove s-polint from comment as it exists no more.
17447 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
17448 Move all the entities in obsolete package System.PolyORB_Interface to
17449 System.Partition_Interface.
17450 (RE_Storage_Size): New function in System.Tasking.
17451 (RE_Get_Ceiling): New entity.

17467 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
17468 properly an attempt to apply Unchecked_Access to a protected operation.
17469 (OK_Self_Reference): New subprogram to check the legality of an access
17470 attribute whose prefix is the type of an enclosing aggregate.
17471 Generalizes previous mechanism to handle attribute references nested
17472 arbitrarily deep within the aggregate.
17473 (Analyze_Access_Attribute): An access attribute whose prefix is a type
17474 can appear in an aggregate if this is a default-initialized aggregate
17475 for a self-referential type.
17476 (Resolve_Attribute, case Access): Ditto.
17477 Add support for new implementation defined attribute Stub_Type.
17478 (Eval_Attribute, case Attribute_Stub_Type): New case.
17479 (Analyze_Attribute, case Attribute_Stub_Type): New case.
17480 (Stream_Attribute_Available): Implement using new subprogram from
17481 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
17482 Has_Specified_Stream_Attribute flag.
17483 Disallow Storage_Size and Storage_Pool for access to subprogram
17484 (Resolve_Attribute, case 'Access et al): Take into account anonymous
17485 access types of return subtypes in extended return statements. Remove
17486 accessibility checks on anonymous access types when Unchecked_Access is
17488 (Analyze_Attribute): Add support for the use of 'Class to convert
17489 a class-wide interface to a tagged type.
17490 Add support for the attribute Priority.
17491 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
17492 whether the designated type is discriminated with a constrained partial
17493 view and require static matching in that case.
17494 Add local variable Des_Btyp. The Designated_Type
17495 of an access to incomplete subtype is either its non-limited view if
17496 coming from a limited with or its etype if regular incomplete subtype.
17498 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
17499 Fix predicate to identify and allow cases of (expander-generated)
17500 references to tag of designated object of a RACW.
17501 (Validate_Static_Object_Name): In Ada 2005, a formal object is
17502 non-static, and therefore cannot appear as a primary in a preelaborable
17504 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
17505 Has_Read_Write_Attributes.
17506 (Has_Read_Write_Attributes): Reimplement in termes of
17507 Has_Stream_Attribute_Definition.
17508 (Missing_Read_Write_Attributes): When checking component types in a
17509 record, unconditionally call Missing_Read_Write_Attributes recursively
17510 (remove guard checking for Is_Record_Type / Is_Access_Type).
17512 2006-10-31 Robert Dewar <dewar@adacore.com>
17514 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
17515 useless assignments here and conditionalize it on absence of exception
17517 (Analyze_Exception_Handlers): Small code reorganization of error
17518 detection code, for new handling of formal packages.
17520 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17521 Hristian Kirtchev <kirtchev@adacore.com>
17523 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
17524 that has been constant-folded, preserve information of original tree,
17526 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
17527 generated private extension declaration if the formal derived type is
17528 synchronized. Carry synchronized present over to the generated private
17530 (Validate_Derived_Type_Instance): Ensure that the actual of a
17531 synchronized formal derived type is a synchronized tagged type.
17532 (Instantiate_Formal_Package): When creating the instantiation used to
17533 validate the actual package of a formal declared without a box, check
17534 whether the formal itself depends on a prior actual.
17535 (Instantiate_Formal_Subprogram): Create new entities for the defining
17536 identifiers of the formals in the renaming declaration, for ASIS use.
17537 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
17538 a renaming declaration or a subtype declaration for an actual in an
17539 instance, capture location information of declaration in generic, for
17541 (Instantiate_Formal_Package): Add comments on needed additional tests.
17542 AI-317 (partial parametrization) is fully implemented.
17543 (Validate_Private_Type_Instance): Add check for actual which
17544 must have preelaborable initialization
17545 Use new // insertion for some continuation messages
17546 (Analyze_Formal_Object_Declaration): Change usage of Expression to
17547 Default_Expression. Add type retrieval when the declaration has an
17548 access definition. Update premature usage of incomplete type check.
17549 (Check_Access_Definition): New subsidiary routine. Check whether the
17550 current compilation version is Ada 05 and the supplied node has an
17552 (Instantiate object): Alphabetize local variables. Handle the creation
17553 of new renaming declarations with respect to the kind of definition
17554 used - either an access definition or a subtype mark. Guard against
17555 unnecessary error message in the context of anonymous access types after
17556 they have been resolved. Add check for required null exclusion in a
17557 formal object declaration.
17558 (Switch_View): A private subtype of a non-private type needs to be
17559 switched (the base type can have been switched without its private
17560 dependents because of the last branch of Check_Private_View.
17561 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
17563 (Instantiate_Type): Emit an error message whenever a class-wide type of
17564 a tagged incomplete type is used as a generic actual.
17565 (Find_Actual_Type): Extend routine to handle a component type in a child
17566 unit that is imported from a formal package in a parent.
17567 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
17568 agree on constrainedness, rather than checking against ultimate ancestor
17569 (Instantiate_Subprogram_Body): Create a cross-reference link to the
17570 generic body, for navigation purposes.
17572 2006-10-31 Robert Dewar <dewar@adacore.com>
17573 Thomas Quinot <quinot@adacore.com>
17575 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
17577 (New_Stream_Subprogram): When processing an attribute definition clause
17578 for a stream-oriented subprogram, record an entity node occurring at
17579 the point of clause to use for checking the visibility of the clause,
17580 as defined by 8.3(23) as amended by AI-195.
17581 (New_Stream_Subprogram): New procedure, factoring behaviour from both
17582 New_Stream_Function and New_Stream_Procedure.
17583 (New_Stream_Function, New_Stream_Procedure): Removed.
17584 (Analyze_Attribute_Definition_Clause, case Address): Check new
17585 Alignment_Check check

17588 Javier Miranda <miranda@adacore.com>
17589 Robert Dewar <dewar@adacore.com>
17591 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
17592 generate the same errors compiling under -gnatc.
17593 (Try_Object_Operation): If no candidate interpretation succeeds, but
17594 there is at least one primitive operation with the right name, report
17595 error in call rather than on a malformed selected component.
17596 (Analyze_Selected_Component): If the prefix is an incomplete type from
17597 a limited view, and the full view is available, use the full view to
17598 determine whether this is a prefixed call to a primitive operation.
17599 (Operator_Check): Verify that a candidate interpretation is a binary
17600 operation before checking the type of its second formal.
17601 (Analyze_Call): Add additional warnings for function call contexts not
17603 (Analyze_Allocator): Move the check for "initialization not allowed for
17604 limited types" after analyzing the expression. This is necessary,
17605 because OK_For_Limited_Init looks at the structure of the expression.
17606 Before analysis, we don't necessarily know what sort of expression it
17607 is. For example, we don't know whether F(X) is a function call or an
17608 indexed component; the former is legal in Ada 2005; the latter is not.
17609 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
17610 were missing. We also didn't handle qualified expressions. Now also
17611 allow function calls. Use new common routine OK_For_Limited_Init.
17612 (Analyze_Type_Conversion): Do not perform some legality checks in an
17613 instance, because the error message will be redundant or spurious.
17614 (Analyze_Overloaded_Selected_Component): Do not do style check when
17615 setting an entity, since we do not know it is the right entity yet.
17616 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
17617 (Analyze_Overloaded_Selected_Component): Same change
17618 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
17619 since regular incomplete subtypes are transformed into corresponding
17620 subtypes of their full views.
17621 (Complete_Object_Operation): Treat name of transformed subprogram call
17622 as coming from source, for browsing purposes.
17623 (Try_Primitive_Operation): If formal is an access parameter, compare
17624 with base type of object to determine whether it is a primitive
17626 (Operator_Check): If no interpretation of the operator matches, check
17627 whether a use clause on any candidate might make the operation legal.
17628 (Try_Class_Wide_Operation): Check whether the first parameter is an
17629 access type whose designated type is class-wide.
17631 2006-10-31 Robert Dewar <dewar@adacore.com>
17632 Ed Schonberg <schonberg@adacore.com>
17633 Gary Dismukes <dismukes@adacore.com>

17636 warn on infinite loops.
17637 Add \\ to some continuation messages
17638 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
17639 (Process_Bounds): If the bounds are integer literals that result from
17640 constant-folding, and they carry a user-defined type, preserve that type
17641 rather than treating this as an integer range.
17642 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
17643 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
17644 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
17645 left hand side of assignment.
17646 (Analyze_Assignment): Add suport to manage assigments to the attribute
17647 priority of a protected object.
17648 (Check_Possible_Current_Value_Condition): Allow fully qualified names
17649 not just identifiers.
17650 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
17651 or AND THEN for possible tracking.
17652 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
17653 case of while loops so we can track values in the loop body.
17655 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17656 Hristian Kirtchev <kirtchev@adacore.com>
17657 Bob Duff <duff@adacore.com>
17659 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
17660 procedure cannot be a protected operation (it is a basic_declaration,
17661 not a subprogram_declaration).
17662 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
17663 Subp. Add logic for entry processing.
17664 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
17665 Determine whether an entry or subprogram of a protected or task type
17666 override an inherited primitive of an implemented interface.
17667 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
17668 Update the actual used in calls to Check_Overriding_Indicator.
17669 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
17670 generate the proper reference to the parent unit, for cross-reference.
17671 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
17673 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17674 (Add_Extra_Formal): Revise procedure to allow passing in associated
17675 entity, scope, and name suffix, and handle setting of the new
17676 Extra_Formals field.
17677 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
17678 pass new parameters. Add support for adding the new extra access formal
17679 for functions whose calls are treated as build-in-place.
17680 (Analyze_A_Return_Statement): Correct casing in error message.
17681 Move Pop_Scope to after Analyze_Function_Return, because an extended
17682 return statement really is a full-fledged scope. Otherwise, visibility
17683 doesn't work right. Correct use of "\" for continuation messages.
17684 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
17685 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
17686 the node doesn't get properly marked as analyzed.
17687 (Analyze_Subprogram_Body): If subprogram is a function that returns
17688 an anonymous access type that denotes a task, build a Master Entity
17690 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
17691 proper usage of null exclusion in a result definition.
17692 (Process_Formals): Code cleanup and new error message.
17693 (Process_Formals): Detect incorrect application of null exclusion to
17695 (Conforming_Types): Handle conformance between [sub]types and itypes
17696 generated for entities that have null exclusions applied to them.
17697 (Maybe_Primitive_Operation): Add an additional type retrieval when the
17698 base type is an access subtype. This case arrises with null exclusions.
17699 (New_Overloaded_Entity): Do not remove the overriden entity from the
17700 homonym chain if it corresponds with an abstract interface primitive.
17701 (Process_Formals): Replace membership test agains Incomplete_Kind with a
17702 call to the synthesized predicate Is_Incomplete_Type.
17703 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
17705 (Analyze_Subprogram_Declaration): Check that abstract interface
17706 primitives are abstract or null.
17707 (Analyze_Subprogram_Specification): Remove previous check for abstract
17708 interfaces because it was not complete.
17709 (Has_Interface_Formals): Removed.
17711 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17712 Javier Miranda <miranda@adacore.com>
17714 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
17715 of Analyze_Package_Body, to create Itype references for anonymous
17716 access types created in the package declaration, whose designated types
17717 may have only a limited view.
17718 (Analyze_Package_Specification): For the private part of a nested
17719 package, install private_with_clauses of enclosing compilation unit if
17720 we are in its visible part.
17721 (Declare_Inherited_Private_Subprograms): Complete barrier
17722 to ensure that the primitive operation has an alias to some parent
17723 primitive. This is now required because, after the changes done for the
17724 implementation of abstract interfaces, the contents of the list of
17725 primitives has entities whose alias attribute references entities of
17726 such list of primitives.
17727 (Analyze_Package_Specification): Simplify code that handles parent units
17728 of instances and formal packages.
17729 (Uninstall_Declarations): Check the convention consistency among
17730 primitive overriding operations of a tagged record type.
17732 2006-10-31 Robert Dewar <dewar@adacore.com>

17734 Javier Miranda <miranda@adacore.com>
17735 Ed Schonberg <schonberg@adacore.com>
17737 * sem_ch8.adb: Minor error msg rewording

17739 expected and found set right)
17740 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
17741 (Analyze_Generic_Renaming): Same fix
17742 (Use_One_Package): Do not take into account the internal entities of
17743 abstract interfaces during the analysis of entities that are marked
17744 as potentially use-visible.
17745 (Find_Type): Handle the case of an attribute reference for
17746 implementation defined attribute Stub_Type (simply let the analysis of
17747 the attribute reference rewrite it).
17748 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
17749 type that appears in a Use_Type clause.
17750 (Analyze_Object_Renaming): Add support for renaming of the Priority
17752 (Find_Type): In Ada 2005, a task type can be used within its own body,
17753 when it appears in an access definition.
17754 (Analyze_Object_Renaming): Remove warning on null_exclusion.
17755 (Analyze_Object_Renaming): Introduce checks for required null exclusion
17756 in a formal object declaration or in a subtype declaration.
17757 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
17758 (Check_Null_Exclusion): New local routine to
17759 Analyze_Subprogram_Renaming. Check whether the formals and return
17760 profile of a renamed subprogram have required null exclusions when
17761 their counterparts of the renaming already impose them.
17762 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
17763 Determine whether an entity is inside a generic scope.
17764 (In_Open_Scope): First pass of documentation update.
17765 (Find_Expanded_Name): Add support for shadow entities associated with
17766 limited withed packages. This is required to handle nested packages.
17767 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
17768 that makes a renaming of a limited withed package illegal.

17771 Ed Schonberg <schonberg@adacore.com>
17773 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
17774 Check_Overriding_Indicator.
17775 (Analyze_Task_Definition): Ditto.
17776 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
17777 (Check_Overriding_Indicator): To find overridden interface operation,
17778 examine only homonyms that have an explicit subprogram declaration, not
17779 inherited operations created by an unrelated type derivation.
17780 (Check_Overriding_Indicator): When checking for the presence of "null"
17781 in a procedure, ensure that the queried node is a procedure
17783 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
17784 type when the formal is an access to variable.
17785 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
17786 (Analyze_Task_Type): Same addition
17787 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
17788 provide navigation capabilities for entries.

17792 Javier Miranda <miranda@adacore.com>
17793 Gary Dismukes <dismukes@adacore.com>
17795 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
17796 inherited from an interface ancestor by another interface in the
17797 context of an instance as 'late'.
17798 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
17799 of a call to a function that dispatches on access result.
17800 (Check_Dispatching_Operation): In case of late overriding of a primitive
17801 that covers abstract interface subprograms we register it in all the
17802 secondary dispatch tables associated with abstract interfaces.
17803 (Check_Dispatching_Call): Add check that a dispatching call is not made
17804 to a function with a controlling result of a limited type. This is a
17805 current implementation restriction.
17806 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
17807 (Check_Dispatching_Operation): Do no emit a warning if the controlling
17808 argument is an interface type that is a generic formal.
17809 (Is_Interface_Subprogram): Removed.
17810 (Check_Dispatching_Operation): If the subprogram is not a dispatching
17811 operation, check the formals to handle the case in which it is
17812 associated with an abstract interface type.

18626 abstract interface type, the static analysis is not enough to know if

18628 we must pass the work to the expander to generate the required code to
18629 evaluate the conversion at run-time.
18630 (Resolve_Equality_Op): Do not apply previous
18631 transformation if expansion is disasbled, to prevent anomalies when

19270 * checks.adb (Build_Discriminant_Checks): If the expression being
19271 checks is an aggregate retrieve the values of its discriminants to
19272 generate the check, rather than creating a temporary and a reference
19274 (Apply_Access_Check): Rewritten to handle new Is_Known_Null flag
19275 (Install_Null_Excluding_Check): Ditto
19276 (Selected_Length_Checks): Build actual subtype for the original Ck_Node,
19277 not for the renamed object, so that the actual itype is attached in the

19286 switches for the compiler.
19287 (Scan_Make_Switches): Do not allow numeric debug switches for gnatmake
19288 (Scan_Make_Switches): When failing with an illegal switch, output an
19289 error message with the full switch.
19290 Eliminate numeric switches for binder/gnatmake
19292 * switch.ads, switch.adb (Bad_Switch): New procedure
19294 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
19295 Remove 0-9 as debug flag character possibilities
19296 -d is now controlling the primary stack size when its value is a
19297 positive. Also add checks against invalid values, and support for kb,
19298 mb. Ditto for -D switch.
19300 2006-02-13 Robert Dewar <dewar@adacore.com>
19301 Serguei Rybin <rybin@adacore.com>
19303 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
19304 save/restore routines.
19305 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19306 were not always properly handled previously.
19307 Since we are changing the tree format anyway, also get rid of the
19308 junk obsolete Immediate_Errors flag.
19309 (Tree_Read): Change the way of reading Tree_Version_String - now we
19310 read the version string from the tree even if its length is not the
19311 same as the length of the version string computed from Gnatvsn.
19312 (Search_Directory_Present): New Boolean flag for the compiler.
19313 Define Tree_Version_String as a dynamic string.
19314 (Default_Stack_Size): new variable, used to handle switch -d.
19317 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
19318 only for main unit.
19319 Add pragma Ada_2005 (synonym for Ada_05)
19320 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19321 were not always properly handled previously.
19323 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
19324 explicit Ada_95 to Ada_2005.
19326 2006-02-13 Javier Miranda <miranda@adacore.com>
19327 Robert Dewar <dewar@adacore.com>
19328 Ed Schonberg <schonberg@adacore.com>
19330 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
19331 against errors in the source program: a private types for which the
19332 corresponding full type declaration is missing and pragma CPP_Virtual
19334 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
19335 (Is_Known_Null): New flag
19336 (Has_Pragma_Pure): New flag
19337 (No_Return): Present in all entities, set only for procedures
19338 (Is_Limited_Type): A type whose ancestor is an interface is limited if
19339 explicitly declared limited.
19340 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
19341 entities. Only used for component marked Is_Tag. If present it stores
19342 the Offset_To_Top function used to provide this value in tagged types
19343 whose ancestor has discriminants.
19345 * exp_ch2.adb: Update status of new Is_Known_Null flag
19347 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
19349 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
19350 the categorization sense if Is_Pure was set by pragma Pure_Function.
19352 2006-02-13 Quentin Ochem <ochem@adacore.com>
19353 Olivier Hainque <hainque@adacore.com>
19355 * bindusg.adb: Updated documentation for -d and -D switches.
19357 * raise.h (__gnat_set_globals): added new parameter for
19358 Default_Stack_Size.
19360 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
19361 (__gnat_handle_vms_condition): Adjust context before raise.
19362 (__gnat_install_handler): Restore the global vector setup for GCC
19363 versions before 3.4, as the frame based circtuitry is not available
19365 (__gnat_set_globals): added a parameter default_stack_size
19366 (__gl_default_stack_size): new variable.
19368 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19370 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
19371 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
19372 does not exist in the Ada RM.
19373 (Compatible_Int_Bounds): Determine whether two integer range bounds
19374 are of equal length and have the same start and end values.
19375 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
19376 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
19377 aggregate when it is part of an object declaration.
19378 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
19379 constrains discriminants of its parent, add explicitly the discriminant
19380 constraints of the ancestor by retrieving them from the
19381 stored_constraint of the parent.
19383 2006-02-13 Robert Dewar <dewar@adacore.com>
19385 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
19386 attribute Mechanism_Code is applied to renamed subprogram, modify
19387 prefix to point to base subprogram.
19388 Max/Min attributes now violate Restriction No_Implicit_Conditionals
19390 * sinfo.ads: Document that Mechanism_Code cannot be applied to
19391 renamed subprograms so that the front-end must replace the prefix
19394 2006-02-13 Javier Miranda <miranda@adacore.com>
19395 Gary Dismukes <dismukes@adacore.com>
19397 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
19398 availability of RE_Interface_Tag.
19399 (Build_Initialization_Call): Fix wrong access to the discriminant value.
19400 (Freeze_Record_Type): Do not generate the tables associated with
19401 timed and conditional dispatching calls through synchronized
19402 interfaces if compiling under No_Dispatching_Calls restriction.
19403 When compiling for Ada 2005, for a nonabstract
19404 type with a null extension, call Make_Controlling_Function_Wrappers
19405 and insert the wrapper function declarations and bodies (the latter
19406 being appended as freeze actions).
19407 (Predefined_Primitive_Bodies): Do not generate the bodies of the
19408 predefined primitives associated with timed and conditional
19409 dispatching calls through synchronized interfaces if we are
19410 compiling under No_Dispatching_Calls.
19411 (Build_Init_Procedure): Use RTE_Available to check if a run-time
19412 service is available before generating a call.
19413 (Make_Controlling_Function_Wrappers): New procedure.
19414 (Expand_N_Full_Type_Declaration): Create a class-wide master for
19415 access-to-limited-interfaces because they can be used to reference
19416 tasks that implement such limited interface.
19417 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
19418 procedure spec and body of the Offset_To_Top function that is generated
19419 when the parent of a type with discriminants has secondary dispatch
19421 (Init_Secondary_Tags): Handle the case in which the parent of the type
19422 containing secondary dispatch tables has discriminants to generate the
19423 correct arguments to call Set_Offset_To_Top.
19424 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
19426 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
19427 Add Wide_[Wide_]Expanded_Name.
19428 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
19429 the same functionality of Get_Prim_Op_Address but applied to predefined
19430 primitive operations because the pointers to the predefined primitives
19431 are now saved in a separate table.
19432 (Parent_Size): Modified to get access to the separate table of primitive
19433 operations or the parent type.
19434 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
19435 functionality of Set_Prim_Op_Address but applied to predefined primitive
19437 (Set_Signature): New subprogram used to store the signature of a DT.
19438 (Displace): If the Offset_To_Top value is not static then call the
19439 function generated by the expander to get such value; otherwise use
19440 the value stored in the table of interfaces.
19441 (Offset_To_Top): The type of the actual has been changed to Address to
19442 give the correct support to tagged types with discriminants. In this
19443 case this value is stored just immediately after the tag field.
19444 (Set_Offset_To_Top): Two new formals have been added to indicate if the
19445 offset_to_top value is static and hence pass this value to the run-time
19446 to store it in the table of interfaces, or else if this value is dynamic
19447 and then pass to the run-time the address of a function that is
19448 generated by the expander to provide this value for each object of the
19451 * rtsfind.ads (Default_Prin_Op_Count): Removed.
19452 (Default_Prim_Op_Count): New entity
19453 (Get_Predefined_Prim_Op_Address): New entity
19454 (Set_Predefined_Prim_Op_Address): New entity
19455 (RE_Set_Signature): New entity

19458 Ed Schonberg <schonberg@adacore.com>
19460 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
19461 Make_Adjust_Call done for a newly-allocated object.
19463 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
19464 in a subprogram are wrapped in a cleanup block, indicate that the
19465 subprogram contains an inner block with an exception handler.
19466 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
19467 Adjust call is for a newly-allocated object. In that case we must not
19468 assume that the finalization list chain pointers are correct (since they
19469 come from a bit-for-bit copy of the original object's pointers) so if
19470 the attach level would otherwise be zero (no change), we set it to 4
19471 instead to cause the pointers to be reset to null.
19473 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
19474 reset chain pointers to null.
19476 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19478 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
19479 string, and the context requires a loop for the assignment (e.g.
19480 because the left-hand side is packed), generate a unique name for the
19481 temporary that holds the string, to prevent spurious name clashes.
19483 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19484 Javier Miranda <miranda@adacore.com>
19485 Robert Dewar <dewar@adacore.com>
19486 Gary Dismukes <dismukes@adacore.com>
19488 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
19489 return unconstrained arrays.
19491 (Expand_Call): An indirect call through an access parameter of a
19492 protected operation is not a protected call.
19493 Add circuit to raise CE in Ada 2005 mode following call
19494 to Raise_Exception.
19495 (Register_DT_Entry): Do nothing if
19496 the run-time does not give support to abstract interfaces.
19497 (Freeze_Subprogram): In case of dispatching operations, do not generate
19498 code to register the operation in the dispatch table if the source
19499 is compiled with No_Dispatching_Calls.
19500 (Register_Predefined_DT_Entry): Generate code that calls the new
19501 run-time subprogram Set_Predefined_Prim_Op_Address instead of
19502 Set_Prim_Op_Address.
19504 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
19505 on array assignments if the right-hand side is a function call that has
19506 been inlined. Check is performed on the assignment in the block.
19507 (Process_Bounds): If bounds and range are overloaded, apply preference
19508 rule for root operations to disambiguate, and diagnose true ambiguity.
19509 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
19510 a tag-indeterminate right-hand side even when Expander_Active is True.
19511 Needed to ensure that dispatching calls to T'Input are allowed and
19512 get the tag of the target class-wide object.
19514 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
19515 an inherited primitive operation that already overrides several
19516 abstract interface primitives. For transitivity, the new entity must
19517 also override all the abstract interface primitives covered by the
19518 inherited overriden primitive.
19519 Emit warning if new entity differs from homograph in same scope only in
19520 that one has an access parameter and the other one has a parameter of
19521 a general access type with the same designated type, at the same
19522 position in the signature.
19523 (Make_Inequality_Operator): Use source locations of parameters and
19524 subtype marks from corresponding equality operator when creating the
19525 tree structure for the implicit declaration of "/=". This does not
19526 change anything in behaviour except that the decoration of the
19527 components of the subtree created for "/=" allows ASIS to get the
19528 string images of the corresponding identifiers.
19529 (Analyze_Return_Statement): Remove '!' in warning message.
19530 (Check_Statement_Sequence): Likewise.
19531 (Analyze_Subprogram_Body): For an access parameter whose designated type
19532 is an incomplete type imported through a limited_with clause, use the
19533 type of the corresponding formal in the body.
19534 (Check_Returns): Implicit return in No_Return procedure now raises
19535 Program_Error with a compile time warning, instead of beging illegal.
19536 (Has_Single_Return): Function returning unconstrained type cannot be
19537 inlined if expression in unique return statement is not an identifier.
19538 (Build_Body_To_Inline): It is possible to inline a function call that
19539 returns an unconstrained type if all return statements in the function
19540 return the same local variable. Subsidiary procedure Has_Single_Return
19541 verifies that the body conforms to this restriction.
19543 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
19544 same type, and one of them is of an anonymous access type, convert
19545 the other operand to it, so that this is a valid binary operation for
19547 (Resolve_Type_Conversion): Handle subtypes of protected types and
19548 task types when accessing to the corresponding record type.
19549 (Resolve_Allocator): Add '\' in 2-line warning message.
19550 Remove '!' in warning message.
19551 (Resolve_Call): Add '\' in 2-line warning message.
19552 (Valid_Conversion): Likewise.
19553 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
19554 resulting type may be an access type with an implicit dereference.
19555 Obtain the proper component from the designated type.
19556 (Make_Call_Into_Operator): Handle properly a call to predefined equality
19557 given by an expanded name with prefix Standard, when the operands are
19558 of an anonymous access type.
19559 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
19560 Explicit_Dereference and Resolve_Selected_Component, to verify that the
19561 prefix of the expression is not of an incomplete type. Allows full
19562 diagnoses of all semantic errors.
19563 (Resolve_Actuals): If the actual is an allocator whose directly
19564 designated type is a class-wide interface we build an anonymous
19565 access type to use it as the type of the allocator. Later, when
19566 the subprogram call is expanded, if the interface has a secondary
19567 dispatch table the expander will add a type conversion to force
19568 the displacement of the pointer.
19569 (Resolve_Call): If a function that returns an unconstrained type is
19570 marked Inlined_Always and inlined, the call will be inlined and does
19571 not require the creation of a transient scope.
19572 (Check_Direct_Boolean_Op): Removed
19573 (Resolve_Comparison_Op): Remove call to above
19574 (Resolve_Equality_Op): Remove call to above
19575 (Resolve_Logical_Op): Inline above, since this is only call.
19576 (Valid_Conversion): Handle properly conversions between arrays of
19577 convertible anonymous access types.
19580 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
19581 the literal in an unchecked conversion, because GCC 4.x needs a static
19582 value for a string bound.
19584 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19585 Hristian Kirtchev <kirtchev@adacore.com>
19587 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
19588 components of the corresponding record, take into account component
19589 definitions that are access definitions.
19590 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
19591 procedure is not considered a dispatching call and will be expanded
19594 2006-02-13 Javier Miranda <miranda@adacore.com>
19596 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
19597 controlling argument of the dispatching call is an abstract interface
19598 class-wide type then we use it directly.
19599 Check No_Dispatching_Calls restriction.
19600 (Default_Prim_Op_Position): Remove the code that looks for the last
19601 entity in the list of aliased subprograms. This code was wrong in
19603 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
19604 when the source is compiled with the No_Dispatching_Calls restriction.
19605 (Init_Predefined_Interface_Primitives): No need to inherit primitives
19606 if we are compiling with restriction No_Dispatching_Calls.
19607 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
19608 subprograms if we are compiling under No_Dispatching_Calls restriction.
19609 (Make_DT): Generate a dispatch table with a single dummy entry if
19610 we are compiling with the No_Dispatching_Calls restriction. In
19611 addition, in this case we don't generate code that calls to the
19612 following run-time subprograms: Set_Type_Kind, Inherit_DT.
19613 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
19614 of this subprogram if compiling with the No_Dispatching_Calls
19616 (Expand_Type_Conversion): Instead of using the actual parameter,
19617 the argument passed as parameter to the conversion function was
19618 erroneously referenced by the expander.
19619 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
19620 Set_Predefined_Primitive_Op_Address and Set_Signature.
19621 (Expand_Dispatching_Call): Generate call to
19622 Get_Predefined_Prim_Op_Address for predefined primitives.
19623 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
19624 predefined primitives.
19625 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
19626 primitives we reserve one dummy entry to ensure that the tag does not
19627 point to some memory that is associated with some other object. In
19628 addition, remove all the old code that generated the assignments
19629 associated with the signature of the dispatch table and replace them
19630 by a call to the new subprogram Set_Signature.
19631 (Set_All_DT_Position): Change the algorithm because now we have a
19632 separate dispatch table associated with predefined primitive operations.
19633 (Expand_Interface_Conversion): In case of non-static offset_to_top
19634 add explicit dereference to get access to the object after the call
19635 to displace the pointer to the object.
19636 (Expand_Interface_Thunk): Modify the generation of the actual used
19637 in the calls to the run-time function Offset_To_Top to fulfil its
19639 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
19641 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19643 * exp_dist.adb (Copy_Specification): For access parameters, copy
19644 Null_Exclusion flag, which will have been set for stream subprograms
19647 2006-02-13 Pascal Obry <obry@adacore.com>
19649 * expect.c (__gnat_expect_portable_execvp): New implementation. The
19650 previous implementation was using the C runtime spawnve routine but
19651 the corresponding wait was using directly the Win32 API. This was
19652 causing some times a lock when waiting for an event using
19653 WaitForSingleObject in __gnat_waitpid. This new implementation uses
19654 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
19655 API fixes this problem.
19657 2006-02-13 Robert Dewar <dewar@adacore.com>
19659 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
19662 2006-02-13 Thomas Quinot <quinot@adacore.com>
19664 * exp_pakd.ads: Fix typos in comments.
19666 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
19667 array reference that is an explicit dereference, mark the converted
19668 (packed) array reference as analyzed to prevent a forthcoming
19669 reanalysis from resetting its type to the original (non-packed) array
19672 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19673 Javier Miranda <miranda@adacore.com>
19674 Eric Botcazou <ebotcazou@adacore.com>
19676 * exp_util.ads, exp_util.adb (Find_Prim_Op,
19677 Is_Predefined_Primitive_Operation): When
19678 searching for the predefined equality operator, verify that operands
19679 have the same type.
19680 (Is_Predefined_Dispatching_Operation): Remove the code that looks
19681 for the last entity in the list of aliased subprograms. This code
19682 was wrong in case of renamings.
19683 (Set_Renamed_Subprogram): New procedure
19684 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
19685 Exp_Type constant computed when entering this subprogram.
19686 (Known_Null): New function
19687 (OK_To_Do_Constant_Replacement): New function
19688 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
19689 (Side_Effect_Free): An attribute reference 'Input is not free of
19690 side effect, unlike other attributes that are functions. (from code
19692 (Remove_Side_Effects): Expressions that involve packed arrays or records
19693 are copied at the point of reference, and therefore must be marked as
19694 renamings of objects.
19695 (Is_Predefined_Dispatching_Operation): Return false if the operation is
19696 not a dispatching operation.
19699 (Remove_Side_Effects): Lift enclosing type conversion nodes for
19700 elementary types in all cases.
19702 2006-02-13 Javier Miranda <miranda@adacore.com>
19704 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
19705 task types when accessing to the corresponding record type.
19706 Remove '!' in warning message.
19708 2006-02-13 Olivier Hainque <hainque@adacore.com>
19710 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
19711 to avoid useless and space inefficient overalignments on targets where
19712 Max_Alignment is larger than 16.
19714 2006-02-13 Pascal Obry <obry@adacore.com>
19716 * g-catiio.adb (Sec_Number): New type used to compute the number of
19717 seconds since 1-1-1970.
19718 (Image) [Natural]: The parameter was an Integer, as we can't deal with
19719 negative numbers (years, months...) it is better to have a Natural here.

19739 * gnatcmd.adb (Rules_Switches): New table
19740 (Add_To_Rules_Switches): New procedure
19741 (GNATCmd): For command CHECK, put all options following "-rules" in the
19742 Rules_Switches table. Append these -rules switches after the -cargs
19745 2006-02-13 Robert Dewar <dewar@adacore.com>
19747 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
19748 These two cases were generating incorrect output, and if this unit
19749 was built with checks on, generated a discriminant mismatch constraint
19752 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19753 Robert Dewar <dewar@adacore.com>
19755 * lib-xref.adb (Get_Type_Reference): For a private type whose full
19756 view is an array type, indicate the component type as well, for
19757 navigation purposes.
19758 (Generate_Reference): Don't consider array ref on LHS to be a case
19759 of violating pragma Unreferenced.
19760 Do not give Ada 2005 warning except on real reference.
19762 2006-02-13 Vincent Celier <celier@adacore.com>
19764 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
19765 main source, add switch -mdebug-main=_ada_ so that the executable can
19766 be debugged by the standard VMS debugger.
19767 (Gnatmake): Set No_Main_Subprogram to True when there is no main
19768 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
19769 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
19770 of the last source, as the binding and linking phases are never
19772 Set all executable obsolete when rebuilding a library.
19774 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
19777 2006-02-13 Javier Miranda <miranda@adacore.com>
19780 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
19781 code to improve the error message reported when the program has
19782 declarations of abstract interface types and it is not compiled with
19783 the -gnat05 switch.
19784 (P_Access_Definition): Reorganize the code to improve the error
19785 message reported when the new Ada 2005 syntax for anonymous
19786 access types is used and the program is not compiled with the

19809 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
19810 unknown, use the location of the project to report the error.
19811 (When_No_Sources): New global variable
19812 (Report_No_Ada_Sources): New procedure
19813 (Check): New parameter When_No_Sources. Set value of global variable

19816 (Get_Sources_From_File): Ditto
19817 (Warn_If_Not_Sources): Better warning messages indicating the unit name
19820 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
19821 Call Prj.Proc.Process with parameter When_No_Sources.
19823 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
19824 Call Recursive_Check with parameter When_No_Sources.
19825 (Recursive_Check): New parameter When_No_Sources. Call itself and
19826 Prj.Nmsc.Check with parameter When_No_Sources.
19827 (Process): New parameter When_No_Sources. Call Check with parameter
19829 (Copy_Package_Declarations): New procedure to copy renamed parameters

19839 When removing nodes (attributes Source_Dirs, Source_Files,
19840 Source_List_File and package Naming), save the comments and attach the
19841 saved comments to the newly created nodes.
19842 Do not add a with clause for the naming package if one already exists.
19844 2006-02-13 Javier Miranda <miranda@adacore.com>

19850 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
19851 aliased entities to look for the overriden abstract interface
19853 (Is_Interface_Subprogram): Complete documentation.
19854 (Check_Dispatching_Operation): Do not generate code to register the
19855 operation in the dispatch table if the source is compiled with
19856 restriction No_Dispatching_Calls.

19858 No_Return procedure with procedure that is not No_Return
19859 (Check_Dispatching_Call): Suppress the check for an abstract operation
19860 when the original node of an actual is a tag-indeterminate attribute
19861 call, since the attribute, which must be 'Input, can never be abstract.
19862 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
19863 call to the Input attribute (even when rewritten).
19864 (Propagate_Tag): Augment comment to indicate the possibility of a call
19865 to an Input attribute.
19867 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
19868 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
19870 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
19871 No_Wide_Characters is no longer partition-wide

19877 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
19879 2006-02-13 Javier Miranda <miranda@adacore.com>
19881 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
19882 handles default-initialized components to keep separate the management
19883 of this feature but also avoid the unrequired resolution and
19884 expansion of components that do not have partially initialized
19886 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
19887 (Check_Bounds): Likewise.
19888 (Check_Length): Likewise.
19890 2006-02-13 Javier Miranda <miranda@adacore.com>
19891 Ed Schonberg <schonberg@adacore.com>
19893 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
19894 abstract interface type call analyze_and_resolve to expand the type
19895 conversion into the corresponding displacement of the
19896 reference to the base of the object.
19897 (Eval_Attribute, case Width): For systems where IEEE extended precision
19898 is supported, the maximum exponent occupies 4 decimal digits.
19899 (Accessibility_Message): Add '\' in 2-line warning message.
19900 (Resolve_Attribute): Likewise.
19901 (case Attribute_Access): Significantly revise checks
19902 for illegal access-to-subprogram Access attributes to properly enforce
19903 the rules of 3.10.2(32/2).
19904 Diagnose use of current instance with an illegal attribute.
19906 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
19908 (Enclosing_Generic_Unit): New function to return a node's innermost
19909 enclosing generic declaration node.
19910 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
19911 (Type_Access_Level): The accessibility level of anonymous acccess types
19912 associated with discriminants is that of the current instance of the
19913 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
19914 (Compile_Time_Constraint_Error): Handle case of conditional expression.
19915 (Kill_Current_Values_For_Entity): New function
19916 (Enter_Name): Change formal type to Entity_Id
19918 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
19919 Ed Schonberg <schonberg@adacore.com>

19922 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
19923 Analyze_Compilation_Unit.
19924 Detect and warn on redundant with clauses detected in a package spec
19925 and/or body when -gnatwr is used.
19926 (Analyze_Context): Analyze config pragmas before other items
19927 (Install_Context_Items): Don't analyze config pragmas here
19928 (Install_Limited_Withed_Unit): Set limited entity of package in
19929 with_clause so that cross-reference information or warning messages on
19930 unused packages can be properly generated
19931 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
19932 has Error_Posted set. Prevent infinite loops in illegal programs.
19933 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
19934 to the point of the error test requiring the current unit to be private.
19935 This ensures that private with clauses are not exempted from the basic
19936 checking for being a descendant of the same library unit parent as a
19937 withed private descendant unit.
19938 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
19939 handle private with clauses properly, as well as to account for cases
19940 where the withed unit is a public descendant of a private ancestor
19941 (in which case the current unit must be a descendant of the private
19942 ancestor's parent). The spec comments were updated accordingly. Also,
19943 the old error message in this subprogram was replaced with error
19944 messages that mirror the errors tested and reported by
19945 Check_Private_Child_Unit.
19946 Parameter and variable names improved for readability.
19947 (Install_Limited_Context_Clauses): Remove test for a withed unit being
19948 private as the precondition for calling
19949 Check_Private_Limited_Withed_Unit since that subprogram has been
19950 revised to test public units as well as private units.

19955 Javier Miranda <miranda@adacore.com>
19957 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
19958 that Scope_Stack.First = 1.
19959 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19960 were not always properly handled previously.
19961 (Formal_Entity): Complete rewrite, to handle properly some complex case
19962 with multiple levels of parametrization by formal packages.
19963 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
19964 to the corresponding derived type declaration for proper semantics.
19966 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
19967 (Check_Component): Enforce restriction on components of
19968 unchecked_unions: a component in a variant cannot contain tasks or
19970 (Unchecked_Union): Allow nested variants and multiple discriminants, to
19972 Add pragma Ada_2005 (synonym for Ada_05)
19973 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19974 were not always properly handled previously.
19975 Document that pragma Propagate_Exceptions has no effect
19976 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
19977 (Set_Convention_From_Pragma): Check that if a convention is
19978 specified for a dispatching operation, then it must be
19979 consistent with the existing convention for the operation.
19980 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
19981 longer required to specify an vtable-ptr component in the record. For
19982 compatibility reasons we leave the support for the previous definition.
19983 (Analyze_Pragma, case No_Return): Allow multiple arguments
19985 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
19986 non-overrideen inherited operation with a controlling result as
19987 illegal only its implicit declaration comes from the derived type
19988 declaration of its result's type.
19989 (Check_Possible_Deferred_Completion): Relocate the object definition
19990 node of the subtype indication of a deferred constant completion rather
19991 than directly analyzing it. The analysis of the generated subtype will
19992 correctly decorate the GNAT tree.
19993 (Record_Type_Declaration): Check whether this is a declaration for a
19994 limited derived record before analyzing components.
19995 (Analyze_Component_Declaration): Diagnose record types not explicitly
19996 declared limited when a component has a limited type.
19997 (Build_Derived_Record_Type): Code reorganization to check if some of
19998 the inherited subprograms of a tagged type cover interface primitives.
19999 This check was missing in case of a full-type associated with a private
20001 (Constant_Redeclaration): Check that the subtypes of the partial and the
20002 full view of a constrained deferred constant statically match.
20003 (Mentions_T): A reference to the current type in an anonymous access
20004 component declaration must be an entity name.
20005 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20006 class_wide type to refer to full type, not to the incomplete one.
20007 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20008 available. Required to give support to the certified run-time.
20009 (Analyze_Component_Declaration): In case of anonymous access components
20010 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20011 (Process_Discriminants): For an access discriminant, use the
20012 discriminant specification as the associated_node_for_itype, to
20013 simplify accessibility checks.
20015 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20016 Javier Miranda <miranda@adacore.com>
20018 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20019 abstract interpretations on an operator, remove interpretations that
20020 yield Address or a type derived from it, if one of the operands is an
20022 (Try_Object_Operation.Try_Primitive_Operation,
20023 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20024 location when creating the new reference to a primitive or class-wide
20025 operation as a part of rewriting a subprogram call.
20026 (Try_Primitive_Operations): If context requires a function, collect all
20027 interpretations after the first match, because there may be primitive
20028 operations of the same type with the same profile and different return
20029 types. From code reading.
20030 (Try_Primitive_Operation): Use the node kind to choose the proper
20031 operation when a function and a procedure have the same parameter
20033 (Complete_Object_Operation): If formal is an access parameter and prefix
20034 is an object, rewrite as an Access reference, to match signature of
20035 primitive operation.
20036 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20037 by an expanded name with prefix Standard, when the operands are of an
20038 anonymous access type.
20039 (Remove_Abstract_Operations): If the operation is abstract because it is
20040 inherited by a user-defined type derived from Address, remove it as
20041 well from the set of candidate interpretations of an overloaded node.
20042 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20045 2006-02-13 Bob Duff <duff@adacore.com>
20047 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20048 redundant use clauses.
20049 In particular, if the scope of two use clauses overlaps, but one is not
20050 entirely included in the other, we should not warn. This can happen
20051 with nested packages.
20052 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20053 reported errors. The bug was reported when the compiler was built
20054 with assertions enabled.
20055 (Find_Type): If the node is a 'Class reference and the prefix is a
20056 synchronized type without a corresponding record, return the type
20059 2006-02-13 Javier Miranda <miranda@adacore.com>
20061 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20062 if this is the full-declaration associated with a private declaration
20063 that implement interfaces, then the private type declaration must be
20065 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20066 as aliased. The use of the 'access attribute is not available for such
20067 object (for this purpose the object should be explicitly marked as
20068 aliased, but being an anonymous type this is not possible).
20070 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20071 Robert Dewar <dewar@adacore.com>
20073 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20074 compilation unit is an elaboration scope.
20075 (Add_Task_Proc): Add '\' in 2-line warning message.
20076 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20078 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20079 Javier Miranda <miranda@adacore.com>
20081 * sem_type.adb (Write_Overloads): Improve display of candidate
20083 (Add_One_Interp): Do not add to the list of interpretations aliased
20084 entities corresponding with an abstract interface type that is an
20085 immediate ancestor of a tagged type; otherwise we have a dummy
20086 conflict between this entity and the aliased entity.
20087 (Disambiguate): The predefined equality on universal_access is not
20088 usable if there is a user-defined equality with the proper signature,
20089 declared in the same declarative part as the designated type.
20090 (Find_Unique_Type): The universal_access equality operator defined under
20091 AI-230 does not cover pool specific access types.
20092 (Covers): If one of the types is a generic actual subtype, check whether
20093 it matches the partial view of the other type.
20095 2006-02-13 Thomas Quinot <quinot@adacore.com>
20097 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20098 line. This is necessary to allow In_Extended_Main_Unit to provide
20099 correct results for itypes while writing out expanded source.
20100 (Close_File): No need to update the source_index_table here since it's
20101 now done for each line.
20103 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20104 Robert Dewar <dewar@adacore.com>
20106 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20107 preserve the source unit where the itype is declared, and prevent a

20117 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
20120 2006-02-13 Bob Duff <duff@adacore.com>
20122 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20123 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20124 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20125 raise Constraint_Error.
20127 * s-vallli.adb (Scan_Long_Long_Integer): Call
20128 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20129 do not scan leading blanks and sign twice.
20130 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20131 raise Constraint_Error.
20133 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20134 Scan_Long_Long_Unsigned): Split out most of the processing from
20135 Scan_Long_Long_Unsigned out into
20136 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20137 This prevents scanning leading blanks and sign twice.
20138 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20141 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20142 out most of the processing from Scan_Unsigned out into
20143 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20144 This prevents scanning leading blanks and sign twice.
20146 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20147 use with Modular'Value attribute.
20148 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

20348 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
20349 link to the version that does nothing. This way the task termination

20351 because of an unhandled exception.
20353 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
20354 handler because of an unhandled exception.
20356 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

20362 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
20363 non-tasking version of the soft link for task termination. We do
20364 nothing since if we are using the non-tasking version it

20367 in charge of finalizing the global list for controlled objects.
20368 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
20369 instead for handling run-time termination in a more flexible way.
20370 (Adafinal_NT): This new procedure will take care of finalizing the
20371 global list for controlled objects if needed, but no tasking
20374 * s-tarest.adb (Task_Lock): Do not try to lock again the
20375 Global_Task_Lock if we already own it. Otherwise, we get blocked in
20376 some run-time operations.
20377 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
20378 until all nested locks have been released.
20379 (Task_Wrapper): Call the fall-back task termination handler. It

20382 procedure for the environment task.
20383 (Task_Wrapper): suppress warnings around declaration of
20384 Secondary_Stack_Address.

20387 moved to the Common_ATCB record.
20388 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
20389 Common_ATCB record.

20391 Common_ATCB record.
20393 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
20394 Fall_Back_Handler, and Specific_Handler.

20397 defined in Ada.Task_Termination, to avoid circular dependencies.
20398 (Termination_Handler): Redefine this type here, alredy defined in
20399 Ada.Task_Termination, for avoiding circular dependencies.
20400 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
20401 for storing task termination handlers. In addition,
20402 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
20403 Common_ATCB because it is used by both the regular and the restricted
20405 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
20406 Common_ATCB because it is used by both the regular and the restricted
20408 (Common_ATCB): Added a dynamic task analyzer field.
20410 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
20411 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.

20413 tasks but the environment task.
20414 (Finalize_Global_Tasks): Call the task termination procedure for the
20415 environment task. The call to Finalize_Global_List is now performed
20416 using the soft links mechanism.
20417 (Task_Wrapper): added dynamic stack analysis.
20419 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
20420 potentially blocking operations has been moved from
20421 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
20422 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
20423 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
20424 this run-time check.
20426 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
20427 of task termination procedure.
20428 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

20470 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
20471 to the specification because the frontend generates code that uses this
20473 (Set_Interface_Table): Add missing assertion.
20474 Update documentation describing the run-time structure.
20475 (Displace): New subprogram that displaces the pointer to the object
20476 to reference one of its secondary dispatch tables.
20477 (IW_Membership): Modified to use the new table of interfaces.
20478 (Inherit_TSD): Modified to use the new table of interfaces.
20479 (Register_Interface_Tag): Use the additional formal to fill the
20480 contents of the new table of interfaces.
20481 (Set_Interface_Table): New subprogram that stores in the TSD the

20496 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
20497 in all the calls to Expand_Interface_Thunk. Instead of referencing the
20498 record component containing the tag of the secondary dispatch table we
20499 have to use the Offset_To_Top run-time function to get this information;
20500 otherwise if the pointer to the base of the object has been displace
20501 we get a wrong value if we use the 'position attribute.
20503 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
20504 all the calls to Expand_Interface_Thunk.
20505 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
20506 interfaces; hence the call to Set_Interface_Table was clearly wrong.

20508 ensure that the interfaces implemented by the ancestors are placed
20509 at the header of the generated list.
20510 (Expand_Interface_Conversion): Handle the case in which the displacement
20511 associated with the interface conversion is not statically known. In
20512 this case we generate a call to the new run-time subprogram Displace.

20514 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
20515 Get_Tagged_Kind and Set_Tagged_Kind.

20538 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
20539 RE_TK_Tagged, RE_TK_Task.
20541 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
20542 Init_Secondary_Tags_Internal to allow its use with interface types and
20543 also to generate the code for the new additional actual required
20544 by Set_Offset_To_Top.
20545 (Build_Init_Statements): In case of components associated with abstract
20546 interface types there is no need to generate a call to its IP.
20547 (Freeze_Record_Type): Generate Select Specific Data tables only for
20549 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
20550 the bodies and specifications of the predefined primitive operations
20551 dealing with dispatching selects and abort, 'Callable, 'Terminated only
20552 for concurrent types.

20557 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
20558 properly protected objects and attach handler in the case of the
20559 restricted profile.
20560 Move embeded package Select_Expansion_Utilities into a separate external

20572 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
20573 pointer initialization values. Make a SAVE_EXPR instead. Add comments
20574 about the use and expansion of SAVE_EXPRs in the various possible
20575 renaming handling cases.
20576 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
20577 abusing DECL_FCONTEXT.

20670 the iterator is quitting iteration on parent directory.
20672 2005-12-09 Javier Miranda <miranda@adacore.com>
20674 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
20675 and the assignment to a class-wide object, before the assignment we
20676 generate a run-time check to ensure that the tag of the Target is
20677 covered by the tag of the source.
20679 2005-12-09 Robert Dewar <dewar@adacore.com>
20681 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean
20682 parameter in call to Image_Wide_Character.

20696 component associated with the secondary table of an abstract interface
20697 type, return the entity associated with such abstract interface type.
20698 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
20699 base type to create anonymous subtype, because entity may be a locally
20700 declared subtype or generic actual.
20701 (Find_Interface): New subprogram that given a tagged type and one of its
20702 component associated with the secondary table of an abstract interface
20703 type, return the entity associated with such abstract interface type.
20705 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
20706 conversion cannot be handled at compile time. In this case we pass this
20707 information to the expander to generate the appropriate code.

20742 copied component does not have a known static Esize, then reset
20743 the size and positional fields of the new component.
20744 (Analyze_Component_Declaration): A limited component is
20745 legal within a protected type that implements an interface.
20746 (Collect_Interfaces): Do not add to the list the interfaces that
20747 are implemented by the ancestors.
20748 (Derived_Type_Declaration): If the parent of the full-view is an
20749 interface perform a transformation of the tree to ensure that it has
20750 the same parent than the partial-view. This simplifies the job of the
20751 expander in order to generate the correct object layout, and it is
20752 needed because the list of interfaces of the full-view can be given in
20754 (Process_Full_View): The parent of the full-view does not need to be
20755 a descendant of the parent of the partial view if both parents are
20757 (Analyze_Private_Extension_Declaration): If declaration has an explicit
20758 "limited" the parent must be a limited type.
20759 (Build_Derived_Record_Type): A derived type that is explicitly limited
20760 must have limited ancestor and progenitors.
20761 (Build_Derived_Type): Ditto.

20772 (Process_Full_View): Improve the check for the "no hidden interface"
20773 rule as defined by AI-396.
20775 2005-12-09 Robert Dewar <dewar@adacore.com>
20777 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
20778 types, not on record subtypes.
20779 (Freeze_Entity): Code cleanup. Add barrier to the loop
20780 that generates the references for primitive operations. This allows to
20781 remove an unnecessary exception handler.

20787 If GNAT CHECK is called with a project file, but with no
20788 source on the command line, call gnatcheck with all the compilable
20789 sources of the project.
20790 Take into account the new command Check, for gnatcheck. Treat as for

20832 available user-specified stream attributes on limited parameters to
20833 also test the type directly rather than only its underlying type (for
20834 Ada 95) and, in the case of Ada 2005, to check that the user-specified
20835 attributes are visible at the point of the subprogram declaration.
20836 For Ada 2005, the error message is modified to indicate that the
20837 type's stream attributes must be visible (again, only for -gnat05).

20869 types use the corresponding record type. This was not needed before
20870 the implementation of Ada 2005 synchronized types because
20871 concurrent types were never tagged types in Ada 95.

20999 * socket.c: Add extern int h_errno for rtems since networking header
21000 files are not available at this point in a tool bootstrap. Newlib

21004 Roger Sayle <roger@eyesopen.com>
21007 * misc.c (internal_error_function): Don't use vsprintf to format
21008 the error message text, instead use pp_format_text and the new

21019 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
21020 a temporary if taking the address of something that is neither
21021 reference, declaration, or constant, since the gimplifier
21022 can't handle that case.
21024 2005-11-17 Laurent Guerby <laurent@guerby.net>
21027 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

21094 * gen-soccon.c: Complete value expansion should not be performed on
21095 TARGET, as it has the form of a math expression, and some components
21096 may be platform-defined macros.
21097 For VxWorks, generate the OK and ERROR values.
21098 New constants giving the sizes of the components of C struct timeval.

21104 * types.ads: Include All_Checks in Suppress_Array
21106 * checks.adb (Check_Needed): Remove kludge for a/=b rewritten as
21107 not(a=b), since we no longer do this rewriting, and hence it is not
21109 (Elaboration_Checks_Suppressed): Add special casing to
21110 deal with different cases of static and dynamic elaboration checks (all
21111 checks does not count in the first case, but does in the second).
21112 (Expr_Known_Valid): Do not assume that the result of any arbitrary
21113 function call is valid, since this is not the case.
21114 (Ensure_Valid): Do not apply validity check to a real literal
21115 in a universal or fixed context
21117 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
21118 elementary types using the operator in standard. It is cleaner not to
21119 modify the programmers intent, especially in the case of floating-point.
21120 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
21121 it did not matter because we always rewrote a/=b to not(a=b).
21122 (Expand_Allocator_Expression): For an allocator expression whose nominal
21123 subtype is an unconstrained packed type, convert the expression to its
21124 actual constrained subtype.
21125 Implement warning for <= or >= where < or > not possible
21126 Fix to Vax_Float tests (too early in many routines, causing premature
21127 Vax_Float expansions.
21129 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
21130 to be used with packages and generic packages as well as with
21132 (Suppress): Set All_Checks, but not Elaboration_Check, for case
21133 of pragma Suppress (All_Checks)
21134 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
21135 a string literal for precise control over warnings.
21136 Avoid raise of pragma in case of unrecognized pragma and just return
21139 * sem_prag.ads: Minor reformatting
21141 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
21142 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter
21143 Switch. Do not handle any exception.
21144 Include -gnatwx as part of -gnatg (warn on redundant parens)
21145 Allow optional = after -gnatm
21146 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
21147 longer sets Elaboration_Checks.
21148 Code to set warning mode moved to Sem_Warn
21149 so that it can be shared by pragma processing.
21151 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
21154 * s-taprop-solaris.adb:
21155 Change some <= to =, to avoid new warning

21163 * exp_vfpt.adb: Handle /= case
21164 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

21172 Increase default priority on Lynx from 15 to 17, and meet the Ada
21173 requirement that Default_Priority be ((Priority'First +
21174 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

21276 we are not defining the type.
21277 <E_Record_Type>: Likewise.
21278 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
21279 to get advantage of the new maybe_stabilize_reference interface, to
21280 ensure that what we reference is indeed stabilized instead of relying
21281 on assumptions on what the stabilizer does.
21282 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
21283 type imported through a limited_with clause, use its non-limited view.
21284 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
21286 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
21287 of #if sections + explicit comparisons of convention identifiers.

21289 before early-returning for certain types when code generation is
21291 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
21292 nullification of gnu_expr we do for objects with address clause and
21293 that we are not defining.
21294 (elaborate_expression_1): Do not create constants when creating
21295 variables needed by the debug info: the dwarf2 writer considers that
21296 CONST_DECLs is used only to represent enumeration constants, and emits
21298 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
21299 object with an address clause into an indirect reference, drop the
21300 initializing expression.
21302 (STACK_CHECK_BUILTIN): Delete.
21303 (STACK_CHECK_PROBE_INTERVAL): Likewise.

21312 subtype to build an actual type with bounds template.
21313 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
21314 is provided by the front-end, use that subtype to compute the size of
21315 the deallocated object.

21317 check for a potential violation of a No_Elaboration_Code restriction.

21322 maybe_stabilize, for common uses without restriction on lvalues and
21323 without need to check for the success indication.
21324 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
21325 pass false instead of 0 as the FORCE argument which is a bool.
21326 (Identifier_to_gnu): Remove checks ensuring that an renamed object
21327 attached to a renaming pointer has been properly stabilized, as no such
21328 object is attached otherwise.
21329 (call_to_gnu): Invoke create_var_decl to create the temporary when the
21330 function uses the "target pointer" return mechanism.
21331 Reinstate conversion of the actual to the type of the formal
21332 parameter before any other specific treatment based on the passing
21333 mechanism. This turns out to be necessary in order for PLACEHOLDER
21334 substitution to work properly when the latter type is unconstrained.

21338 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
21339 with extra arguments to control whether to recurse through non-values
21340 and to let the caller know if the stabilization has succeeded.
21342 * utils2.c (gnat_build_constructor): Only sort the fields for possible
21343 static output of record constructor if all the components are constant.
21344 (gnat_build_constructor): For a record type, sort the list of field
21345 initializers in increasing bit position order.
21346 Factor common code to build a storage type for an unconstrained object
21347 from a fat or thin pointer type and a constrained object type.
21348 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
21349 types variants, and process special cases of VIEW_CONVERT expressions
21350 as their NOP_EXPR counterpart to ensure we get to the
21351 CORRESPONDING_VARs associated with CONST_DECls.
21352 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
21353 on the right-hand side.
21355 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring

21358 are converting back to its original type.
21359 (convert) <JM input>: Fallthrough regular conversion code instead of
21360 extracting the object if converting to a type variant.
21361 (create_var_decl): When a variable has an initializer requiring code
21362 generation and we are at the top level, check for a potential violation
21363 of a No_Elaboration_Code restriction.
21364 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
21365 SIZE and SIZE_UNIT which we need for later back-annotations.

21368 is an unchecked union.

21370 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
21371 main variant, just replace the VIEW_CONVERT_EXPR.

21507 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
21508 for task component, in the case of a limited aggregate. The enclosed

21547 and related): For a prefix that is an explicit dereference of an
21548 access to unconstrained packed array type, annotate the dereference
21549 with an actual subtype so GIGI can make a correct size computation.
21550 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
21551 'Unrestricted_Access, if the designated type is an interface we
21552 add a type conversion to force the displacement of the pointer
21553 to the secondary dispatch table.
21554 Use Universal_Real instead of Long_Long_Float when we need a high
21555 precision float type for the generated code (prevents gratuitous
21556 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
21557 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
21558 'Terminated for task interface class-wide objects. Generate a call to
21559 the predefined dispatching routine used to retrieve the _task_id from
21560 a task corresponding record.

21585 if-statement that has elsif_parts, recompute the Current_Value node
21586 for any entity whose value is known from the condition of the first
21588 (Expand_N_Return_Statement): When returning a mutable record, convert
21589 the return value into its actual subtype in order to help the backend
21590 to return the actual size instead of the maximum. This is another
21591 aftermath of not returning mutable records on the sec-stack anymore.
21593 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
21594 handling of error msg for suspicious reverse range iteration.

21610 a process handle, not need to convert.
21611 (__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.
21613 * g-expect.adb: (Kill): Document the new close parameter.
21614 (Close): Do not release the process handle in the kill there as

21616 (Send_Signal): Release the process handle.
21618 2005-11-14 Robert Dewar <dewar@adacore.com>
21620 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

21622 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
21625 * exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we

21922 leave it more clear.
21923 (Analyze_Type_Declaration): If type has previous incomplete tagged

21980 whose default is abstract because the object type itself is abstract.
21981 (Find_Type): If the type is incomplete and appears as the prefix of a
21982 'Class reference, it is tagged, and its list of primitive operations
21983 must be initialized properly.

22013 statement to inhibit warning.
22014 (Resolve_Unary_Op): Do not produce a warning when
22015 processing an expression of the form -(A mod B)
22016 Use Universal_Real instead of Long_Long_Float when we need a high

22859 of constants that is consistent with the contents of g-soccon.ads.
22860 This change also makes gen-soccon self-contained (removing dependencies
22861 upon GCC internal headers).
22863 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
22865 (To_Inet_Addr): Now a procedure instead of a function, more efficient.
22867 * socket.c: Minor reformatting.

22999 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23000 from object notation, the original node is unanalyzed and carries no
23001 semantic information, so that accessiblity checks must be performed on
23002 the type of the actual itself.
23003 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23004 compatibility with Build_Protected_Sub_Specification.

23018 whether a potential circularity is harmless, because it includes units
23019 loaded through a limited_with clause. Extends previous treatment which
23020 did not handle properly arbitrary combinations of limited and
23021 non-limited clauses.

23058 position set is provided, we compute one in order to reduce the maximum
23059 length of the keys. This computation first selects a character
23060 position between 1 and the minimum length of the keys in order to
23061 avoid reducing one of the keys to an empty string.
23062 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23063 does not converge. The initialization procedure now comes with a
23064 maximum number of iterations such that when exceeded, an exception is
23065 raised in Compute. The user can initialize this ratio to another value
23067 Reformating and updated headers.

23071 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
23072 that given an entity T creates and returns an Itype that duplicates the
23073 contents of T. The returned Itype has the null-exclusion
23074 attribute set to True, and its Etype attribute references T
23075 to keep the association between the two entities.

23171 Preset_Names for Name_Disp_Asynchronous_Select,
23172 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23173 Name_Disp_Timed_Select.
23174 New pragma Debug_Policy
23176 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23178 Switch -gnata also sets Debug_Pragmas_Enabled
23180 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23181 handle an explicit -gnata when compiling predefined files.
23183 2005-09-01 Vincent Celier <celier@adacore.com>
23185 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23186 directories of projects that have no Ada sources.
23188 2005-09-01 Robert Dewar <dewar@adacore.com>
23190 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23191 (makes a difference for wide characters)
23193 * widechar.adb, widechar.ads:
23194 Add Wide_Char_Byte_Count feature to count chars vs bytes
23196 2005-09-01 Thomas Quinot <quinot@adacore.com>
23197 Ed Schonberg <schonberg@adacore.com>
23198 Robert Dewar <dewar@adacore.com>
23200 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23201 'Address attribute reference with an overloaded prefix, use the
23202 location of the prefix (not the location of the attribute reference) as
23203 the error location.
23204 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23205 a function renaming thereof, is a valid prefix for 'Size (where it is
23206 intepreted as a function call).
23207 (Statically_Denotes_Entity): New predicate to determine whether the
23208 prefix of an array attribute can be considered static.
23211 (Eval_Attr): Fix failure to evaluate Component_Size for

23222 Ed Schonberg <schonberg@adacore.com>
23224 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23225 become local to the whole package.
23226 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23227 the package was already analyzed the new algorithm "replaces" the
23228 real entities by the shadow ones. This is required to ensure that
23229 the order of these entities in the homonym chains does not change;
23230 otherwise we can have undefined references at linking time because
23231 in case of conflicts the external name of the entities will have
23232 a suffix that depends on the order of the entities in the chain.
23233 (Remove_Limited_With_Clause): Complementary code that completes the
23234 new algorithm and replaces the shadow entities by the real ones.
23235 (Install_Limited_Withed_Unit): When unchaining entities before the
23236 installation of the shadow entities, only regular entities of the
23237 public part must be taken into account. This is required to
23238 keep this routine in synch with the work done by Remove_Limited_
23240 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
23241 even if unit is analyzed, because the analysis of the unit is
23242 idempotent in any case, and the limited view of the unit may have to
23243 be installed for proper visibility.
23244 (Expand_Limited_With_Clause): Even if the unit in the implicit
23245 with_clause has been analyzed already, a limited view of the package
23246 must be built for the current context, if it does not exist yet.

23249 Javier Miranda <miranda@adacore.com>
23250 Gary Dismukes <dismukes@adacore.com>
23252 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
23253 defining entity for the instance body, make a new defining identifier
23254 rather than copying the entity of the spec, to prevent accidental
23255 sharing of the entity list.
23256 (Check_Private_View): When exchanging views of private types, build the
23257 list of exchanged views as a stack, to ensure that on exit the exchanges
23258 are undone in the proper order.
23259 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
23260 Restore the compilation environment in case of instantiation_error.
23261 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
23262 for an anonymous access result.
23263 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
23264 (Formal_Entity): Handle properly the case of a formal package that
23265 denotes a generic package renaming.
23267 2005-09-01 Thomas Quinot <quinot@adacore.com>
23269 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
23270 clause if the array aggregate is surrounded by parentheses.

23273 Gary Dismukes <dismukes@adacore.com>
23274 Ed Schonberg <schonberg@adacore.com>
23275 Javier Miranda <miranda@adacore.com>
23277 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
23279 to check if a type is Constrained in cases related to code generation
23280 (rather than semantic checking) since otherwise we do not generate
23281 similar code for mutable private types depending if their
23282 discriminants are visible or not.
23283 (Check_Abstract_Overriding): Do not complain about failure to override
23284 the primitive operations used in dispatching selects since they will
23285 always be overriden at the freeze point of the type.
23286 (Access_Definition): Separate out handling for resetting the scope
23287 of an anonymous access function result type. Retrieve the scope
23288 of the associated function rather than using Current_Scope, which
23289 does not have a consistent value (depends on whether we're in the
23290 middle of analyzing formal parameters). Add ??? comment about
23291 finding a cleaner way to handle the special cases of scope setting.
23292 (Process_Incomplete_Dependents): A protected operation is never a
23293 dispatching operation (only its wrapper may be).
23294 (Build_Derived_Record_Type): In case of tagged private types that
23295 implement interfaces add derivation of predefined primitive
23297 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
23298 by two parameters that are used in case of derivation from abstract
23299 interface types: No_Predefined_Prims is used to avoid the derivation
23300 of predefined primitives from the interface, and Predefined
23301 Prims_Only is used to complete the derivation predefined primitives
23302 in case of private tagged types implementing interfaces.
23303 Fix typo in comments
23304 (Find_Interface_In_Descendant): Protect the frontend against
23305 wrong code with large circularity chains.
23306 (Is_Private_Overriding): Add support for entities overriding interface
23307 subprograms. The test failed because Entities associated with overriden
23308 interface subprograms are always marked as hidden (and used to build
23309 the secondary dispatch table); in this case the overriden entity is
23310 available through the field abstract_interface_alias (cf. override_
23311 dispatching_operation)
23312 (Access_Definition): Set the scope of the type to Current_Scope for the
23313 case of a function with an anonymous access result type.
23314 (Access_Subprogram_Declaration): Handle creation of the type entity for
23315 an access-to-function type with an anonymous access result.
23316 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
23317 in handling for N_Access_Function_Definition.
23318 (Analyze_Subtype_Declaration): Modify the text of error message.
23319 (Derived_Type_Declaration): Modify the text of error message.
23320 (Process_Subtype): Modify the text of error message plus cleanup
23321 of one redundant error message.
23322 (Analyze_Component_Declaration): Code cleanup.
23323 (Analyze_Object_Declaration): Code cleanup.
23324 (Analyze_Subtype_Declaration): Propagate the null-exclusion
23325 attribute in case of access types. Code cleanup.
23326 (Array_Type_Declaration): Code cleanup.
23327 (Process_Discriminants): Create the new null-excluding itype
23328 if required. Code cleanup.
23329 (Process_Subtype): Create the new null-excluding itype if
23330 required. Code cleanup.
23331 (Build_Derived_Record_Type): Code cleanup to avoid calling
23332 twice the subprogram derive_subprograms in case of private
23333 types that implement interfaces. In this particular case the
23334 subprogram Complete_Subprograms_Derivation already does the
23335 job associated with the second call.
23337 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
23338 conversion to the full view when generating an operation for a
23339 discriminant whose type may currently be private.
23341 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23342 Javier Miranda <miranda@adacore.com>
23344 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
23345 V (Obj.F), the rewriting does not involve the indexed component, but
23346 only the selected component itself.
23347 Do not apply the transformation if the analyzed node is an actual of a
23348 call to another subprogram.
23349 (Complete_Object_Operation): Retain the entity of the
23350 dispatching operation in the selector of the rewritten node. The
23351 entity will be used in the expansion of dispatching selects.
23352 (Analyze_One_Call): Improve location of the error message associated
23354 (Analyze_Selected_Component): No need to resolve prefix when it is a
23355 function call, resolution is done when parent node is resolved, as
23357 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
23358 when attempting to resolve a call transformed from its object notation.
23359 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
23360 of the argument list for each interpretation of the operation.
23361 (Try_Object_Operation): The designated type of an access parameter may
23362 be an incomplete type obtained through a limited_with clause, in which
23363 case the primitive operations of the type are retrieved from its full
23365 (Analyze_Call): If this is an indirect call, and the return type of the
23366 access_to_subprogram is incomplete, use its full view if available.
23368 2005-09-01 Javier Miranda <miranda@adacore.com>
23369 Gary Dismukes <dismukes@adacore.com>
23371 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
23372 access types the null-exclusion and access-to-constant attributes must
23374 (Analyze_Return_Statement): When the result type is an anonymous access
23375 type, apply a conversion of the return expression to the access type
23376 to ensure that appropriate accessibility checks are performed.
23377 (Analyze_Return_Type): For the case of an anonymous access result type,
23378 generate the Itype and set Is_Local_Anonymous_Access on the type.
23379 Add ??? placeholder for check to disallow returning a limited object
23380 in Ada 2005 unless it's an aggregate or a result of a function call.
23381 Change calls from Subtype_Mark to Result_Definition.
23382 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
23383 Result_Definition in call to Make_Function_Specification.
23384 (Build_Body_To_Inline): Change Set_Subtype_Mark to
23385 Set_Result_Definition.
23386 (Make_Inequality_Operator): Change formal Subtype_Mark to
23387 Result_Definition in call to Make_Function_Specification.
23388 (Process_Formals): Create the new null-excluding itype if required.
23389 (New_Overloaded_Entity): For an entity overriding an interface primitive
23390 check if the entity also covers other abstract subprograms in the same
23391 scope. This is required to handle the general case, that is, overriding
23392 other interface primitives and overriding abstract subprograms inherited
23393 from some abstract ancestor type.
23394 (New_Overloaded_Entity): For an overriding entity that comes from
23395 source, note the operation that it overrides.
23396 (Check_Conformance, Type_Conformant): Addition of one new formal
23397 to skip controlling formals in the analysis. This is used to
23398 handle overloading of abstract interfaces.
23399 (Base_Types_Match): Add missing case for types imported from
23400 limited-with clauses
23401 (New_Overloaded_Entity): Add barrier to protect the use of
23402 the "alias" attribute.
23404 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23406 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
23407 verify that the procedure and the entry are mode conformant.
23408 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
23409 as a different operator, which is often a cut-and-paste error.
23411 2005-09-01 Javier Miranda <miranda@adacore.com>
23412 Ed Schonberg <schonberg@adacore.com>
23414 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
23415 used in controlling parameters exclude null because it is necessary to
23416 read the tag to dispatch, and null has no tag.
23417 (Override_Dispatching_Operation): If the previous operation is inherited
23418 from an interface, it becomes hidden and does not participate in later
23421 2005-09-01 Javier Miranda <miranda@adacore.com>
23422 Ed Schonberg <schonberg@adacore.com>
23423 Gary Dismukes <dismukes@adacore.com>
23425 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
23426 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
23427 the expander will generate the corresponding run-time check to evaluate
23429 (Resolve_Call): Check for legal type of procedure name or prefix that
23430 appears as a trigger in a triggering alternative.
23431 (Valid_Conversion): If expression is ambiguous and the context involves
23432 an extension of System, remove System.Address interpretations.
23433 (Resolve_Qualified_Expression): Reject the case of a specific-type
23434 qualification applied to a class-wide argument. Enhance comment
23435 to explain checking of Original_Node.
23436 (Resolve_Type_Conversion): The location of the error message was not
23437 general enough to handle the general case and hence it has been removed.
23438 In addition, this patch improves the text of the message.
23439 (Resolve_Type_Conversion): Add missing support for access to interface
23441 (Resolve_Type_Conversion): If the target is a class-wide interface type,
23442 do not expand if the expression is the actual in a call, because proper
23443 expansion will take place when the call itself is expanded.
23444 (Resolve_Allocator): If the context is an unchecked conversion, the
23445 allocator inherits its storage pool, if any, from the target type of
23448 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23449 Javier Miranda <miranda@adacore.com>
23451 * sem_type.adb (Add_One_Interp): If a candidate operation is an
23452 inherited interface operation that has an implementation, use the
23453 implementation to avoid spurious ambiguities.
23454 (Interface_Present_In_Ancestor): In case of concurrent types we can't
23455 use the Corresponding_Record_Typ attribute to look for the interface
23456 because it is set by the expander (and hence it is not always
23457 available). For this reason we traverse the list of interfaces
23458 (available in the parent of the concurrent type).
23459 (Interface_Present_In_Ancestor): Handle entities from the limited view
23461 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23463 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
23464 from the list of required components.
23465 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
23466 primitive procedure of a limited interface with a controlling first
23468 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
23470 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
23471 capture if it is generated in the second operand of a short-circuit
23473 Do not capture values for variables with address clauses.
23474 (Is_Object_Reference): Treat a function call as an object reference only
23475 if its type is not Standard_Void_Type.
23477 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23479 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
23480 to a variable that is statically known to be constant.

23497 Document new treatment of wide characters in max line length
23499 Remove -gnatL/-gnatZ switches, no longer used.
23500 Add note on pragmas Assertion_Policy and Debug_Policy in discussion

23504 Float_Representation.
23505 Add documentation for pragma No_Strict_Aliasing

24262 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
24263 longer protected objects. They have been replaced by lower-level
24264 suspension objects made up by a mutex and a condition variable (or
24265 their equivalent given a particular OS) plus some internal data to
24266 reflect the state of the suspension object.
24267 (Initialize, Finalize): Add this initialization procedure for
24268 Suspension_Object, which is a controlled type.
24269 (Finalize): Add the finalization procedure for Suspension_Object,
24270 which is a controlled type.
24272 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
24273 Ada.Synchronous_Task_Control because there is no longer a need for a
24274 VxWorks specific version of this package. Target dependencies
24275 has been moved to System.Task_Primitives.Operations.
24277 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
24279 (InitializeCriticalSection, EnterCriticalSection,
24280 LeaveCriticalSection, DeleteCriticalSection): Replace the type
24281 pCriticalSection by an anonymous access type so that we avoid problems
24282 of accessibility to local objects.

24288 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
24289 set the environment task mask here.
24290 (Current_State): Add this function that returns the state of the
24292 (Set_False): Add this procedure that sets the state of the suspension
24294 (Set_True): Add this procedure that sets the state of the suspension
24295 object to True, releasing the task that was suspended, if any.
24296 (Suspend_Until_True): Add this procedure that blocks the calling task
24297 until the state of the object is True. Program_Error is raised if
24298 another task is already waiting on that suspension object.
24299 (Initialize): Add this procedure for initializing the suspension
24300 object. It initializes the mutex and the condition variable which are
24301 used for synchronization and queuing, and it sets the internal state
24303 (Finalize): Add this procedure for finalizing the suspension object,
24304 destroying the mutex and the condition variable.

24309 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
24310 which provides a low-level abstraction (using operating system
24311 primitives) for Ada.Synchronous_Task_Control.
24312 This object is made up by a mutex (for ensuring mutual exclusion), a
24313 condition variable (for queuing threads until the condition is
24314 signaled), a Boolean (State) indicating whether the object is open,
24315 and a Boolean (Waiting) reflecting whether there is a task already
24316 suspended on this object.

24333 System.Parameters.No_Abort is True.
24335 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
24336 is no longer done in the body of s-taprop

24581 type derivation of private tagged types implementing interfaces.
24582 In this case some interface primitives may have been overriden

24672 * i-cpp.ads, i-cpp.adb:
24673 This package has been left available for compatibility with previous
24674 versions of the frontend. As part of the new layout this is now a

24728 access to subprograms must be recursive.
24729 (Is_Unchecked_Conversion): Improve the test that recognizes
24730 instantiations of Unchecked_Conversion, and allows them in bodies that
24731 are to be inlined by the front-end. When the body comes from an

24756 the case where the discriminant belongs to a nonlimited type, since
24757 such discriminants have their accessibility level defined in the same
24758 way as a normal component of an anonymous access type.
24759 (Resolve_Allocator): When an allocator's designated type is a class-wide
24760 type, check that the accessibility level of type given in the
24761 allocator's expression or subtype indication is not statically deeper

24780 constant-folded, there is nothing to check.
24781 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
24782 check on possible violation of restriction No_Direct_Boolean_Operators

25086 the "simple_choice" member in a variant record, in accordance with the
25087 description in the package spec: the information output for a constant
25088 should be "S number", not "SS number".
25089 (Get_Encoded_Name): Return at once if not generating code. Avoids name

25789 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

25792 error messages if expansion has been disabled due to previous
25793 (unrelated) errors).
25795 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
25796 is disabled, the entity denoted by the argument is the access type
25797 itself, not an underlying record type, so there is no need to go back
25798 to the Corresponding_Remote_Type.

25808 denotes a type in the class.
25809 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
25810 of Name_Generic_Dispatching_Constructor.
25812 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

25827 the case of renaming of stream attributes when the renaming denotes a
25828 generic formal subprogram association for an abstract formal subprogram.
25829 Check that the attribute is a primitive stream attribute (and not
25830 a class-wide stream attribute) and then rewrite the attribute name
25831 as the name of the appropriate compiler-generated stream primitive.

25835 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

25843 itype whose parent is controlled and not yet frozen, do not create a
25844 freeze node for the itype if expansion is disabled.
25846 2005-03-29 Vincent Celier <celier@adacore.com>
25848 * make.adb (Gnatmake): Don't fail if the main project file is declared
25849 as having no Ada sources. Do not display message "no sources to

26504 * a-stunau.ads, a-stunau.adb:
26505 Change interface to allow efficient (and correct) implementation

26551 Update documentation on Must_Be_Byte_Aligned for new spec
26553 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
26554 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
26555 uses of the Access_Disp_Table attribute to reference the first dispatch
26556 table associated with a tagged type. As
26557 part of the implementation of abstract interface types,
26558 Access_Disp_Table has been redefined to contain a list of dispatch
26559 tables (rather than a single dispatch table).
26560 Similarly, upgrade all the references to Tag_Component by the
26561 new attribute First_Tag_Component.
26562 (Find_Inherited_TSS): Moved to exp_tss.

26570 Bit packed array ops are only called if operands are known to be
26572 (Component_Equality): When returning an N_Raise_Program_Error statement,
26573 ensure that its Etype is set to Empty to avoid confusing GIGI (which
26574 expects that only expressions have a bona fide type).
26575 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
26576 determine the amount of data to be copied.
26578 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
26579 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):

26606 (Task_Body_Procedure): Removed.
26607 (Set_Task_Body_Procedure): Removed.
26608 These subprogram have been removed because the attribute
26609 Task_Body_Procedure has been moved to the corresponding task type
26610 or task subtype entity to leave a field free to store the list
26611 of interfaces implemented by a task (for AI-345)
26612 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
26613 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
26614 expression flag Do_Range_Check

26630 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
26631 attribute Task_Body_Procedure rather than the old semantic field that
26632 was available in the task_type_declaration node.
26634 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
26635 interface type definitions.
26636 (P_Formal_Derived_Type_Definition): Modified to handle the list of
26639 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a

26676 expression to the type of the object when the object is constant.
26677 Reverse defer_debug_incomplete_list before traversing it, so that trees
26678 are processed in the order at which they were added to the list. This
26679 order is important when using the stabs debug format.
26680 If we are deferring the output of debug information, also defer this
26681 output for a function return type.
26682 When adding fields to a record, prevent emitting debug information
26683 for incomplete records, emit the information only when the record is
26685 (components_to_record): New parameter defer_debug.

26696 Convert to use ANSI-style prototypes. Remove unused
26697 declarations for emit_stack_check, elab_all_gnat and

26722 Expansion_Delayed and handle case when it's inside an
26723 N_Qualified_Expression.
26725 * sem_ch3.adb (Derived_Type_Declaration): New predicate
26726 Comes_From_Generic, to recognize accurately that the parent type in a
26727 derived type declaration can be traced back to a formal type, because
26728 it is one or is derived from one, or because its completion is derived
26730 (Constrain_Component_Type): If component comes from source and has no
26731 explicit constraint, no need to constrain in in a subtype of the
26733 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
26734 Minor change to propagate Is_Ada_2005 flag

26741 function returns "by target", dereference the target pointer using the
26742 type of the actual return value.
26743 <all>: Be prepared for a null gnu_result.
26744 (processed_inline_subprograms): Check flag_really_no_inline

26757 System.Pack_nn unit.
26759 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
26761 Needed now that we do some processing for IN parameters as well. This
26762 may well fix some unrelated errors.
26763 (Expand_Call): Handle case of unaligned objects (in particular those
26764 that come from packed arrays).
26765 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
26766 renamed entity is an inherited operation, re-expand the call using the
26767 original operation, which is the one to call.
26768 Detect attempt to inline parameterless recursive subprogram.
26769 (Represented_As_Scalar): Fix to work properly with private types
26770 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
26771 accurate estimate. Yields True in far fewer cases than before,
26772 improving the quality of code that depends on this test.
26774 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
26775 over both visible and private declarations to remove them from tree,
26776 and mark subprograms declared in package as eliminated, to prevent
26777 spurious use in subsequent compilation of generic units in the context.
26779 * exp_util.ads: Minor cleanup in variable names
26781 * sem_eval.ads, sem_eval.adb: Minor reformatting

26788 of an initialization call.
26790 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26792 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
26793 that appears in the instantiation rather than the internal subtype
26794 generated in the wrapper package, to avoid anomalies in gigi when the
26795 target is derived from a private type whose full view is an access type.
26797 2005-03-15 Robert Dewar <dewar@adacore.com>
26799 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,

26807 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
26808 here from exp_attr so it can be shared between exp_attr and exp_dist.
26809 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
26810 all TSS names, not a subset thereof, and the previous name introduced
26811 an unnecessarily confusion that a distinction might exist between
26812 "OK" TSS names and some "not OK" TSS names.
26814 2005-03-15 Doug Rupp <rupp@adacore.com>
26816 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
26819 2005-03-15 Pascal Obry <obry@adacore.com>
26820 Eric Botcazou <ebotcazou@adacore.com>
26824 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
26825 when IN_RTS. This is to work around a bootstrap path problem.
26827 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
26828 table and pass it to __gnat_install_SEH_handler().
26829 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.

26835 Vincent Celier <celier@adacore.com>
26836 Arnaud Charlet <charlet@adacore.com>
26839 This change works fine when gnatlib is built from the gcc directory,
26840 but does not work when using the libada Makefile, since GCC_FOR_TARGET
26841 is not passed to ada/Makefile.in, so more work is needed by a
26842 Makefile/configure expert.
26844 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
26845 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
26846 Setup gnatlink switch -M for x86_64 linux, as it is already setup
26848 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
26849 Run ranlib on libgccprefix.a
26850 Define PREFIX_OBJS for Darwin, to build libgccprefix.
26851 (ADA_INCLUDE_SRCS): Split Ada packages.
26853 2005-03-15 Robert Dewar <dewar@adacore.com>
26855 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
26857 * impunit.adb: Add GNAT.UTF_32
26859 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
26861 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
26862 now uses GNAT.UTF_32).
26864 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
26865 capabilities for categorizing characters using Unicode categories
26867 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26869 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
26870 instantiation that has been rewritten as a package body, retrieve spec
26871 to generate proper name for implicit_with_clause.
26872 (Install_Parents): Recognize a parent that is an instantiation but has
26873 been rewritten as a package declaration during analysis.
26875 2005-03-15 Javier Miranda <miranda@adacore.com>
26876 Ed Schonberg <schonberg@adacore.com>
26878 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
26879 parameter reported some error we immediately return. This improves the
26880 behaviour of the frontend in case of errors.
26881 (Install_Parent, Remove_Parent): Introduce new flag
26882 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
26883 ancestor of a generic child unit, when the child is being instantiated.
26884 (Inline_Instance_Body): If we are compiling the private
26885 part or the body of a child unit, restore the proper visibility of the
26886 parents after compiling the instance body.
26888 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26889 Javier Miranda <miranda@adacore.com>
26892 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
26893 of a private type, in which case it is underlying_type that denotes
26894 the proper task. Also modified to use the new entity attribute
26895 that is directly available in the task type and task subtype entities
26896 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
26897 arrays when other dimensions than the first are constrained by
26898 discriminants of an enclosing record.
26899 (Insert_Explicit_Dereference): If the prefix is an indexed component or
26900 a combination of indexed and selected components, find ultimate entity
26901 and generate the appropriate reference for it, to suppress spurious
26903 (Note_Possible_Modification): If an entity name has no entity, return.
26904 (Is_Variable): A function call never denotes a variable.
26905 (Requires_Transient_Scope): For record types, recurse only on
26906 components, not on internal subtypes that may have been generated for
26907 constrained components.
26909 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26911 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
26912 Eliminated as candidates for resolution. Both efficient, and avoids
26913 anomalies with operators declared in deleted code.
26914 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
26915 expansion is disabled (as when compiling a generic) to prevent spurious
26916 warnings on prefixes of selected components.
26918 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26920 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
26921 attached to a list before checking whether it appears in the private
26922 declarations of the current package.
26923 (Make_Inequality_Operator): Insert declaration in proper declarative
26924 list rather than just setting the Parent field, so that
26925 Is_Private_Declaration can handle it properly.
26927 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26929 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
26930 a renaming a body, check that the renamed subprogram in not intrinsic.
26931 (Find_Direct_Name): If several use_visible entities hide
26932 each other, and the context is a predefined file compiled through
26933 rtsfind, keep only the entity that comes from a predefined file.
26935 2005-03-15 Geert Bosch <bosch@adacore.com>
26937 * s-fatgen.adb (Valid): Extend special exceptions to account for long
26938 long float padding to also cover AMD64 and IA64.
26940 2005-03-15 Gary Dismukes <dismukes@adacore.com>
26942 * s-imgwch.adb: Add with and use of Interfaces.

27324 (Unit_Declaration_Node): Ditto.
27325 (Is_Variable_Prefix): For the case of an indexed component whose prefix
27326 has a packed array type, the prefix has been rewritten into a type

27332 * stringt.ads, stringt.adb: Handle full UTF-32 range.
27333 Remove ["0A"] from comment, since it can look like a line terminator.
27334 Currently we don't permit this, but this is under discussion by the
27335 ARG, and it is easy enough to use a different example.
27337 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
27338 handling UTF-32 encoding for wide wide character.

27397 describing the new layout.
27398 (Dispatch_Table): The expander computes the actual array size, allocates
27399 the Dispatch_Table record accordingly, and generates code that displaces
27400 the base of the record after the Typeinfo_Ptr component. The access to
27401 these components is done by means of local functions.
27402 (Offset_To_Top): New function.
27403 (Typeinfo_Ptr): New function.
27404 (Get_TSD): Modified to access the new position of the TSD.
27405 (Set_TSD): Modified to save the TSD in its new position.

27418 dispatching, setting the controlling status of the formal parameters
27419 and result, and issuing an error if there is no controlling type for
27420 the formal subprogram.
27421 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
27422 which is an unclean use of that field, we set the new field
27423 Corresponding_Formal_Spec to make the formal subprogram available to

27431 abstract formal subprograms in error check for functions returning
27432 abstract types. Set scope of new designator for

27434 body for nested subprograms, before full analysis of said body.
27435 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
27436 subprogram only if inner one comes from source.
27437 (Analyze_Function_Call): If the call is given in object notation, the

27439 argument list. After analyzing the name, if the call has been rewritten
27440 and the result type is set, no further analysis is needed.
27441 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
27442 mark in function specification, in a context where the formals are
27443 visible and hide outer homographs.
27445 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
27446 as the tagged type for the cases of abstract formal subprograms and
27447 renamings of those. Clean up spec comments.
27448 (Check_Dispatching_Context): Add error message to indicate "abstract
27449 procedure", covering the case of a call to a formal abstract procedure
27450 that has statically tagged operands.
27451 (Check_Dispatching_Call): Check for the case of an actual given by
27452 a tag-indeterminate function call whose type is an ancestor of the
27453 containing call's associated tagged type. This situation can occur
27454 for inherited primitives with function defaults. In this case we
27455 use the tagged type's tag directly as the controlling argument for
27457 (Expand_Call): Name change on call to Expand_Dispatch_Call.
27459 * sprint.adb (Sprint_Node_Actual): Split
27460 N_Formal_Subprogram_Declaration into two alternatives for the new

27559 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
27560 component of an array of arrays in an assignment context, and the
27561 aggregate has component associations that require sliding on
27562 assignment, force reanalysis of the aggregate to generate a temporary
27563 before the assignment.
27564 (Must_Slide): Make global to the package, for use in Gen_Assign.
27566 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27568 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
27569 unchecked union with no inferable discriminants, return a
27570 Raise_Program_Error node, rather than inserting it at the point the
27572 (Expand_Record_Equality, Component_Equality): Handle properly the case
27573 where some subcomponent is an unchecked union whose generated equality

27582 Arnaud Charlet <charlet@adacore.com>
27584 * init.c (__gnat_initialize): Add a new parameter eh which contains the
27585 address of the exception registration. The Win32 version of this
27586 routine calls __gnat_install_SEH_handler() to initialize the SEH
27587 (Structured Exception Handling) handler.
27588 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
27589 SEH (Structured Exception Handling) now.
27590 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
27591 (__gnat_initialize for ppc-vxworks): Adjust comments and the
27592 preprocessor condition protecting the call to the extra eh setup
27593 subprogram, which is only available for the ppc target.

27607 Update copyright notice.
27609 * s-tassta.adb (Task_Wrapper): Declare the exception registration

27641 * prj-makr.adb (Process_Directory): Put file name in canonical case
27642 before matching against the patterns.
27643 If gnatname has been invoked as <prefix>-gnatname
27644 then invoke the compiler as <prefix>-gcc, not just "gcc".
27646 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27648 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
27649 with expansion disabled. The actual subtype is needed among other
27650 places when the selected component appears in the context of a loop
27651 bound, and denotes a packed array.
27652 (Operator_Check): Always use the first subtype in the
27653 error message, to avoid the appearance of internal base types.
27654 (Transform_Object_Operation): Copy each actual in full
27655 to the parameter associations of the constructed call, rather than
27656 using the shallow copy mechanism of New_Copy_List. This ensures that
27657 the chaining of named associations is done properly.
27658 (Complete_Object_Operation): Rewrite node, rather than
27659 replacing it, so that we can trace back to the original selected
27662 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
27663 and calls that use object notation, if the called function is not
27664 declared in a withed unit, place the elaboration constraint on the
27665 unit in the context that makes the function accessible.
27666 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
27667 imposes an elaboration constraint between two packages.
27669 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27671 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
27672 views of a private type after handling its private dependents, to
27673 maintain proper stack discipline between entry and exit from the

27694 Slight fix to documentation of -gnaty with no parameters
27696 * xr_tabls.ads: Add ??? comment for missing overall comment
27698 * xsinfo.adb: Make default file name be sinfo.h, since this is what
27699 we now use by default.
27701 * xsnames.adb: Adjust end of file test to look for five space followed
27702 by '#' instead of six spaces. The format of xsnames.adb was modified
27703 in the last update.
27705 * a-numeri.ads: Add reference to AI-388 for greek letter pi
27708 * clean.adb: Minor reformatting.
27710 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,

27714 * csets.adb: Eliminate obsolete comment
27716 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
27719 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
27721 2005-02-09 Sergey Rybin <rybin@adacore.com>
27723 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
27724 the difference between compact and incompact layout and add the record
27725 representation clause to the example illustrating different layouts.
27726 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
27727 component clauses").
27729 2005-02-09 Florian Villoing <villoing@adacore.com>
27731 * gnat_ugn.texi: Fix typos.
27732 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
27734 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"

27779 * exp_util.ads: Minor correction in comment.
27781 2005-02-09 Arnaud Charlet <charlet@adacore.com>
27783 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,

28033 * decl.c (compatible_signatures_p): New function. The intended purpose
28034 is to check if two function signatures for a call-site and a callee are
28035 compatible enough for the call to be valid. The underlying purpose is
28036 to check if a call to a mapped builtin is using the right interface.
28037 The current code actually does not check antyhing - this a placeholder

28089 structure of GARLIC and PolyORB RPC receivers.
28090 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
28092 Simplify elaboration code for RCI packages.
28094 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver
28095 generation to reduce differences between the structure of GARLIC and

28178 * s-fileio.adb (Temp_File_Record): Change length of string component
28179 Name from L_tmpnam + 1 to max_path_len + 1.

28204 note that it applies to obsolete GNAT features, which was previously
28205 omitted. Second we contrast the behavior with that of the new
28206 Ada 2005 AI-368 restriction No_Obsolescent_Features.
28207 Preliminary rewriting of GNAT & libraries chapter in order to take
28208 into account default project locations & new project manager

28440 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
28441 fields claimed addressable still have to be bitfields. Use
28442 value_factor_p instead of a raw binop construction to check for the
28443 position's alignment.

28450 Ed Schonberg <schonberg@adacore.com>
28452 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
28453 with an implicit dereference as its prefix, use
28454 Insert_Explicit_Dereference instead of merely rewriting the prefix into

28456 prefix is generated, if appropriate.
28458 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
28459 dereference is rewritten to an explicit one, generate a reference to
28460 the entity denoted by its prefix using the original prefix node, so

28462 access value, if appropriate.
28464 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
28465 emitting 'assigned but never read' warning on a variable on the basis

28479 an external name, to be handled by the back end.
28481 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
28482 subprogram which is Imported with convention Intrinsic if an
28483 External_Name argument is specified.
28484 (Process_Import_Or_Interface): Properly diagnose link name argument.
28485 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

28541 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
28542 and the Has_Pragma_Unreferenced flag for each formal before analyzing
28543 the body, to ensure that warnings are properly emitted for each accept
28544 statement of a given task entry.

28566 (Remove_Next_Debug): Same fix
28568 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do

28572 (Remove_Next): Same cleanup
28574 2004-12-07 Thomas Quinot <quinot@adacore.com>
28576 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
28577 used to record an implicit dereference as a read operation on its
28578 prefix when operating under -gnatc. Necessary to avoid spurious
28579 'variable assigned but never read' warnings in that mode.
28580 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
28581 is a non-overloaded implicit dereference, call the above subprogram to
28582 ensure proper recording of references.
28584 2004-12-07 Gary Dismukes <dismukes@adacore.com>
28586 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

28634 2004-12-07 Vincent Celier <celier@adacore.com>
28636 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
28637 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
28638 and -eit to -ept. Added qualifier
28639 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
28641 2004-11-27 Andreas Schwab <schwab@suse.de>

28647 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
28648 internal implementation unit GNAT.Sockets.Thin,
28649 as their usage for sockets is non-portable (using the read and write
28650 functions from the system runtime library is fine on UNIX but won't

28704 (Setup_Exception): Do nothing in the GNAT SJLJ case.
28706 * gigi.h (others_decl, all_others_decl): New decls representing the
28707 new Others_Value and All_Others_Value objects.
28708 (struct attrib): Rename "arg" component as "args", since GCC expects a
28709 list of arguments in there.
28711 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
28712 corresponding objects exported by a-exexpr, instead of hardcoded dummy
28715 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
28716 others_decl and all_others_decl instead of hardcoded dummy addresses
28717 to represent "others" and "all others" choices, which is cleaner and
28718 more flexible with respect to the possible eh pointer encoding policies.
28720 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
28721 (process_attributes): Account for the naming change of the "args"
28722 attribute list entry component.
28724 * decl.c (build_attr_list): Rename into prepend_attributes to allow
28725 cumulating attributes for different entities into a single list.
28726 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
28727 attributes for the current entity and propagate first subtype
28728 attributes to other subtypes.
28729 <E_Procedure>: Attribute arguments are attr->args and not
28730 attr->arg any more.
28731 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
28732 argument provided, as this is what GCC expects. Use NULL_TREE instead
28735 2004-11-18 Robert Dewar <dewar@adacore.com>
28737 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

28770 (First_RCI_Subprogram_Id): Document this constant.
28771 (Add_RAS_Access_TSS): Correct the setting of the Etype of the

28774 replaced with calls to Get_Library_Unit_Name_String. Previously there
28775 were several instances of the same code in different locations in the
28776 compiler; this checkin completes the replacement of all of these
28777 instances with calls to a common subprogram.
28778 Minor reformatting.
28780 * sem_dist.adb: Remove comment noting that RPC receiver generation
28781 should be disabled for RACWs that implement RASs.
28782 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
28784 * sem_util.ads, sem_util.adb (Has_Stream): New function
28785 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
28786 qualified name of a library unit into the name buffer.
28787 (Note_Possible_Modification): Generate a reference only
28788 if the context comes from source.
28790 * snames.ads (PCS_Names): New subtype corresponding to names of
28791 supported implementations of the Partition Communication Subsystem
28792 (PCS) (i.e. the runtime library support modules for the distributed
28795 2004-11-18 Robert Dewar <dewar@adacore.com>
28796 Ed Schonberg <schonberg@adacore.com>
28798 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
28799 (Has_Rep_Pragma): New function
28800 (Has_Attribute_Definition_Clause): New function
28801 (Record_Rep_Pragma): Moved here from sem_ch13.adb
28802 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
28804 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
28806 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
28807 (Expand_Pragma_Psect_Object): New procedure
28808 These procedures contain the revised and cleaned up processing for
28809 these two pragmas. This processing was formerly in Sem_Prag, but
28810 is more appropriately moved here. The cleanup involves making sure
28811 that the pragmas are properly attached to the tree, and that no
28812 nodes are improperly shared.
28814 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
28815 pragmas to Exp_Prag, which is more appropriate.
28816 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
28817 check for duplicates Remove use of Is_Psected flag, no longer needed.
28818 Use new Make_String_Literal function with string.
28820 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
28821 that are functions return universal values, that have to be converted
28822 to the context type.
28823 Use new Make_String_Literal function with string.
28824 (Get_Stream_Convert_Pragma): New function, replaces the use of
28825 Get_Rep_Pragma, which had to be kludged to work in this case.
28827 * freeze.adb: Use new Has_Rep_Pragma function
28829 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
28830 function with string.
28831 Use new Has_Rep_Pragma function.
28833 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
28836 2004-11-18 Robert Dewar <dewar@adacore.com>
28838 * errout.ads, errout.adb: (First_Sloc): New function
28840 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
28841 check (-gnatyx) instead of being included as a redundant construct
28844 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
28845 Style_Check_Order_Subprograms.
28847 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
28848 stylesw.adb: Add Style_Check_Xtra_Parens
28850 * usage.adb: Add line for -gnatyx (check extra parens)
28852 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
28854 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28855 Robert Dewar <dewar@adacore.com>
28857 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
28858 discriminant of a constrained subtype, analyze the copy of the
28859 corresponding constraint, because in some cases it may be only
28860 partially analyzed.
28861 Removes long-lived ??? comments.
28863 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
28864 handled controlled or secondary-stack expressions within the
28865 iteration_scheme of a loop.
28867 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
28868 bounds that may contain functions calls, to prevent memory leaks when
28869 the bound contains a call to a function that uses the secondary stack.
28870 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
28871 generate temporaries for loop bounds that might contain function calls
28872 that require secondary stack and/or finalization actions.
28874 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
28875 selected component and the selector is overloadable (not just a
28876 function) treat as function call, Analyze_Call will disambiguate if
28878 (Analyze_Selected_Component): Do not generate an actual subtype for the
28879 selected component if expansion is disabled. The actual subtype is only
28880 needed for constraint checks.
28881 (Analyze_Allocator): If restriction No_Streams is set, then do
28882 not permit objects to be declared of a stream type, or of a
28883 composite type containing a stream.
28885 * restrict.ads: Remove the a-stream entry from Unit_Array, since
28886 No_Streams no longer prohibits with'ing this package.
28888 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
28889 discriminants, but the parent base has unknown discriminants, there is
28890 no discriminant constraint to inherit. Such a discrepancy can arise
28891 when the actual for a formal type with unknown discriminants is a
28892 similar private type whose full view has discriminants.
28893 (Analyze_Object_Declaration): If restriction No_Streams is set, then
28894 do not permit objects to be declared of a stream type, or of a
28895 composite type containing a stream.
28897 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28899 * exp_dbug.ads: Update documentation to reflect simpler encoding for
28900 protected operations.
28902 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
28903 generated name, it complicates decoding in gdb and hinders debugging
28904 of protected operations.
28905 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
28906 flag for the protected entry barrier function.
28907 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
28908 flag for the protected entry function.
28910 2004-11-18 Nicolas Setton <setton@adacore.com>
28912 * expect.c: Define __unix__ when __APPLE__ is defined.
28914 * Makefile.in: Inform the value of the variable GMEM_LIB in the
28915 Darwin-specific section.
28917 * lang-specs.h: Change the placement of the %1 marker.
28918 Works around the fact that gcc adds -fPIC by default under Darwin.
28920 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28922 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
28923 type of the object with the packed array type, set the Analyzed flag
28924 on the object if it is an entity or simple indexed component, to avoid
28925 spurious type errors.
28927 2004-11-18 Gary Dismukes <dismukes@adacore.com>
28929 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
28930 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
28931 separate line from the version message.
28933 2004-11-18 Ed Falis <falis@adacore.com>
28935 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
28937 (init_float): Eliminate initialization of floating point status for
28938 AE653. The instructions have no effect for vThreads.
28940 2004-11-18 Vincent Celier <celier@adacore.com>
28942 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
28943 gnatbind is invoked with -shared.
28945 2004-11-18 Jose Ruiz <ruiz@adacore.com>
28947 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
28948 for Detect_Blocking which is redundant with the check done within the
28949 procedure Protected_Single_Entry_Call.
28950 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
28951 Detect_Blocking which is redundant with the check done within the
28952 procedure Protected_Single_Entry_Call.
28954 2004-11-18 Vincent Celier <celier@adacore.com>
28956 * makegpr.adb (Compile): Put the compiling switches (in package
28957 Compiler and on the command line) immediately after "-c", instead of
28958 at the end of the command line invocation of the compiler, when
28959 compiling a non-Ada file.
28960 (Build_Global_Archive): When there is no need to rebuild the archive,
28961 set Global_Archive_Exists, so that the archive is passed to the linker
28964 2004-11-18 Robert Dewar <dewar@adacore.com>
28965 Sergey Rybin <rybin@adacore.com>
28968 Remove extra paren check from list of checks for redundant constructs
28969 Add documentation of new -gnatyx style check (check extra parens)
28970 Remove paragraph about gnatelim debug options.
28972 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
28973 objects rather than forbidding dependencies on the package Ada.Streams.
28975 * sinfo.ads: Add ??? note that we should document pragmas passed to
28978 * g-expect.ads: Fix a few typos in the comments.
28980 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
28982 * misc.c (gnat_handle_option): Use %< and %> for quoting in
28985 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
28987 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
28989 2004-11-07 Andreas Schwab <schwab@suse.de>
28991 * Makefile.in (install-gnatlib): Remove spurious hyphen.
28993 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
28996 * Makefile.in (darwin): Set soext to .dylib.
28998 2004-10-26 Vincent Celier <celier@gnat.com>
28999 Thomas Quinot <quinot@act-europe.fr>
29001 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29002 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29003 there is no use of GNAT.Sockets.Constants.
29004 Remove remaining pragma Import for C_Write
29005 Remove C_Read and C_Write from internal implementation unit
29006 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29007 the read and write functions from the system runtime library is fine
29008 on UNIX but won't work under Windows).
29010 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29011 (Check_Selector): Use C_Recv instead of C_Read.
29012 Selectors are the GNAT.Sockets abstraction to perform a select()
29013 call on a set of descriptors. To allow abortion of an ongoing
29014 select operation, some data is written to a dedicated socket that
29015 is always monitored.
29016 Under Windows, the write and read library functions cannot operate
29017 on sockets, so we need to use send and recv instead, which is portable
29018 across all supported platforms.
29020 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29021 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29022 (using the read and write functions from the system runtime library is
29023 fine on UNIX but won't work under Windows).
29025 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29027 * mlib-tgt-darwin.adb: New file.
29029 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29030 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29031 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29032 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29035 * Makefile.in: Add support for building shared libraries under Darwin.
29036 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29037 the low level EH init subprogram to be called from __gnat_initialize.
29039 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29040 indicates which options to pass to the archive indexer.
29042 * mlib-utl.adb: Add support for calling ranlib with additional
29043 options. This is needed for instance under Mac OS X.
29044 (Ranlib_Options): New global variable, used to store the potential
29045 options to pass to ranlib.
29046 (Ar): Use Ranlib_Options when spawning ranlib.
29047 (Initialize): Set the value of ranlib option.
29049 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29051 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29052 instead of 8K, to reflect the real potential needs for stack-checking
29055 2004-10-26 Pascal Obry <obry@gnat.com>
29057 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29059 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29060 Windows only the initial thread stack size can be set so it is good to
29061 start we a low stack size.
29062 The OS will adjust the size as needed.
29064 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29065 Nicolas Setton <setton@act-europe.fr>
29067 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29068 "__unix__" instead of "unix".
29069 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29070 sections were just mistakenly ignored. The former is
29071 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29072 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29073 of hpux. This prevents an unwanted definition of the symbol
29074 convert_addresses in adaint.o.
29076 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29078 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29079 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29081 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29083 * a-filico.ads, a-filico.adb: fix incorrect header.
29085 2004-10-26 Javier Miranda <miranda@gnat.com>
29087 * a-ststio.ads: Fix typo in identifier
29089 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29091 * sem_ch4.adb: Minor reformatting.
29093 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29095 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29096 enabled, check the result of unary and binary operations when the
29097 expression is the right-hand side of an assignment.
29099 2004-10-26 Vincent Celier <celier@gnat.com>
29101 * clean.adb (Delete): Do not output warnings when in quiet output and
29102 not in verbose mode.
29103 (Force_Deletions): New Boolean flag, defaulted to False
29104 (Delete): Only delete a file if it is writable, and when
29105 Force_Deletions is True.
29106 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29107 (Usage): Line for new switch -f
29108 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29111 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29113 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29114 JM type only if its size matches that of the wrapper. When a size is
29115 prescribed and the field is not aliased, remove the wrapper of a JM
29116 type only if the size is not greater than that of the packed array.
29117 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29120 2004-10-26 Geert Bosch <bosch@gnat.com>
29122 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29123 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29124 (Pred): Implement in terms of Succ.
29126 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29128 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29129 unchecked conversion is safe for in-place use if the expression of the
29130 conversion is safe.
29131 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29132 be expandable in place even if the aggregate does not come from source.
29133 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29134 designated object of an allocator in place, rather than building it
29135 first on the stack. The previous scheme forces a full copy of the array,
29136 and may be altogether unsusable if the size of the array is too large
29137 for stack allocation.
29139 2004-10-26 Robert Dewar <dewar@gnat.com>
29141 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29142 compares if the component is atomic.
29144 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29145 array assignment if the component type is atomic.
29147 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29148 Eric Botcazou <ebotcazou@act-europe.fr>
29150 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29151 is aliased and is a by_reference type, do not pass by copy.
29152 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29153 detect whether the call is in the right side of an assignment or
29154 the expression of an object declaration. Recurse on component
29155 association within aggregates.
29156 Call it in the condition that determines whether the temporary is
29157 necessary for correct stack-checking.
29159 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29161 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29162 RACW_Type, used in the PolyORB version.
29163 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29164 version and the GARLIC version.
29166 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29167 Rename RCI_Info to RCI_Locator for better consistency between the
29168 GARLIC and PolyORB versions of the distributed systems annex.
29169 (DSA_Implementation_Name): This enumeration lists the possible
29170 implementations of the Partition Communication Subsystem for the
29171 Distributed Systems Annex (DSA). The three available implementations
29172 are the dummy stub implementation (No_DSA), and two versions based on
29173 two different distribution runtime libraries: GARLIC and PolyORB. Both
29174 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29176 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29179 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29180 between the GARLIC and PolyORB versions of the distributed systems
29182 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29184 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29186 * gnat1drv.adb: Suppress calling the back end when
29187 Frontend_Layout_On_Target is true.
29189 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29191 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29192 Set_Read_Only): New subprograms.
29193 These new routines allow the user to set or unset the Owner execute
29194 and Owner write permission flags on a file.
29196 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29197 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29199 2004-10-26 Matthew Gingell <gingell@gnat.com>
29201 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29203 2004-10-26 Pascal Obry <obry@gnat.com>
29205 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29206 memory before the faulting page we properly test the process read
29207 access for this address using appropriate Win32 routine.
29208 (HPUX sections): guard with "__hpux__" instead of "hpux".
29210 2004-10-26 Robert Dewar <dewar@gnat.com>
29212 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29213 entry parameter if pragma Unreferenced set, since we do not properly
29214 handle the case of multiple parameters.
29216 2004-10-26 Vincent Celier <celier@gnat.com>
29218 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29219 (Ada_Objects_Path.Add): For a library project, add to the object path
29220 the library directory only if there is no object directory or if the
29221 library directory contains ALI files.
29222 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29224 2004-10-26 Vincent Celier <celier@gnat.com>
29226 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29227 extension of library projects.
29229 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29230 path defaults to ".:<prefix>/lib/gnat".
29231 (Parse): For an extending all project, allow direct import of a project
29232 that is virtually extended.
29234 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29235 the specified name is directly imported, return its ID. Otherwise, if
29236 an extension of this project is imported, return the ID of the
29239 2004-10-26 Robert Dewar <dewar@gnat.com>
29241 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
29242 (Sub3): New procedure, used by Scaled_Divide
29243 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
29244 correct more than one instance of failure to propagate carries
29246 (Double_Divide): Handle overflow case of largest negative number
29247 divided by minus one.
29249 * s-arit64.ads (Double_Divide): Document that overflow can occur in
29250 the case of a quotient value out of range.
29253 2004-10-26 Robert Dewar <dewar@gnat.com>
29255 * s-bitops.adb (Bit_Eq): Remove redundant check.
29257 * s-bitops.ads: Minor comment updates
29258 Change some occurrences of Address to System.Address
29260 * s-carsi8.ads: Fix minor cut-and-paste error in comments
29262 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29264 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
29265 accessibility check to prefix that is a protected operation.
29267 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29269 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
29270 empty, post message on stub.

29273 Javier Miranda <miranda@gnat.com>
29275 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
29276 current instance appears within a unit that is directly in the context
29278 Used to determine whether the body of the instance should be analyzed
29279 immediately after its spec, to make its subprogram bodies available
29280 for front-end inlining.
29281 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
29282 constraint is not allowed on the component type (AARM 12.5.3(3))
29284 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29286 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
29287 'Storage_Pool): enhance, document & limit detection of non-sharable
29290 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
29292 * s-pooglo.ads: Add more documentation now that this pool is properly
29295 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29297 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
29298 or protected type with discriminants, do not constrain the
29299 corresponding record type if the subtype declaration has no
29300 discriminant constraints. This can be the case in source code, or in
29301 the subtype declaration created to rename an actual type within an
29304 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29306 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
29307 different kind of stub (possibly wrong name for file), do not check
29309 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
29310 includes call to some function that returns an unconstrained type, do
29313 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29315 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
29316 appear in the code for the main unit. Dependencies among units in the
29317 context of the main unit are established when those other units are
29318 compiled. Otherwise spurious elaboration constraints can generate
29319 incorrect elaboration circularities.
29321 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29322 Ed Schonberg <schonberg@gnat.com>
29324 * sem_util.adb (Is_Aliased_View): Defend against the case where this
29325 subprogram is called with a parameter that is not an object name. This
29326 situation arises for some cases of illegal code, which is diagnosed
29327 later, and in this case it is wrong to call Is_Aliased, as that might
29328 cause a compiler crash.
29329 (Explain_Limited_Type): Refine previous fix to include
29330 inherited components of derived types, to provide complete information.
29332 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
29333 is the prival for a protected object.
29334 It is necessary to mark this entity as a variable, in addition to
29335 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
29336 modified to avoid checking the Aliased flag on entities that are not
29337 objects. (Checking that flag for non-objects is erroneous and could
29338 lead to a compiler crash).
29340 2004-10-26 Robert Dewar <dewar@gnat.com>
29342 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
29343 X_Frac = 0.5, then we know that the number X must be positive.
29344 (Succ): Remove the same redundant test, and also fix the primary test
29345 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
29347 (Decompose): Add fuller comments to spec
29349 2004-10-26 Pascal Obry <obry@gnat.com>
29351 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
29352 validity (process must have read access). Set to 0 in all other cases.
29353 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
29354 violation on Win32.
29355 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
29356 segmentation violation.
29358 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29360 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
29361 whose type is a constructed subtype of an aliased object with an
29362 unconstrained nominal subtype, convert the actual to the constructed
29363 subtype before taking its address.
29365 2004-10-26 Vincent Celier <celier@gnat.com>
29367 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
29368 (Is_Path_Name_Case_Sensitive): New function
29370 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
29371 (Base_Name, Simple_Name, Current_Directory, Compose,
29372 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
29375 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29376 Vasiliy Fofanov <fofanov@act-europe.fr>
29377 Vincent Celier <celier@gnat.com>
29379 * gnat_ugn.texi: Generalize "finding memory problems" section into a
29380 "memory management issues" section and document some of the useful
29381 memory pools provided as part of the GNAT library.
29382 Remove "virtual" from declaration of A::method2 in
29383 the simple example of Ada/C++ mixed system.
29384 Library Projects may be virtually extended: their virtual extensions
29385 are not Library Projects.
29386 Added section on extending project hierarchies.
29388 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
29390 * adaint.c (__gnat_get_libraries_from_registry): Cast value
29392 (__gnat_portable_spawn): Remove const.
29394 * mingw32.h (MAXPATHLEN): Check for previous definition.
29396 2004-10-17 Matthias Klose <doko@debian.org>
29398 * gnatvsn.ads: Set gnat library version to 4.0.
29400 2004-10-05 Vincent Celier <celier@gnat.com>
29402 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
29404 2004-10-04 Laurent Guerby <laurent@guerby.net>
29407 * Makefile.in: Define and use RANLIB_FLAGS.
29409 2004-10-04 Pascal Obry <obry@gnat.com>
29411 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
29412 other x86 platforms).
29414 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
29416 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
29417 in general and triggers stack alignment adjustment for thread entry
29418 points on targets where this is necessary.
29420 2004-10-04 Bernard Banner <banner@gnat.com>
29423 * Makefile.in: Add section for powerpc linux
29424 Add variant i-vxwork-x86.ads
29426 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
29428 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
29430 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
29431 table registration calls when need be. Ensures no reference to the crt
29432 ctors symbol are issued in the SJLJ case, which avoids possible
29433 undefined symbol errors in the case of modules to be statically linked
29436 2004-10-04 Javier Miranda <miranda@gnat.com>
29438 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
29439 in-line the code corresponding to subprogram Analyze_Actuals. In
29440 addition, analyze the actuals only in case of subprogram call.
29442 2004-10-04 Ed Falis <falis@gnat.com>
29444 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
29446 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
29448 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
29449 in the documentation.
29451 2004-10-04 Robert Dewar <dewar@gnat.com>
29453 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
29455 (Analyze_Block_Statement): Add circuitry to detect following dead code
29456 (Check_Unreachable_Code): Handle case of block exit
29458 2004-10-04 Robert Dewar <dewar@gnat.com>
29460 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
29461 (XMatchD): Avoid warning for Logic_Error call
29463 2004-10-04 Robert Dewar <dewar@gnat.com>
29465 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
29466 consider expressions buried within a procedure actual to be an actual.
29467 This caused some blowups with uses of packed slices within a procedure
29470 2004-10-04 Robert Dewar <dewar@gnat.com>
29472 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
29473 longer need to be initialized to zero.
29474 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
29475 initialized to zero.
29477 * checks.adb (Expr_Known_Valid): Packed arrays are now always
29478 considered valid, even if the representation is modular. That's correct
29479 now that we no longer initialize packed modular arrays to zero.
29481 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
29482 suffixes. These are now documented as the only cases in which the
29483 debugger ignores outer records.
29484 Previously, the spec allowed arbitrary suffixes for this purpose.
29485 Change name of LJM to JM for packed array pad records
29486 Create separate section on packed array handling, and add a whole new
29487 set of comments to this section describing the situation with packed
29488 modular types and justification requirements depending on endianness.
29490 2004-10-04 Robert Dewar <dewar@gnat.com>
29492 * a-except.adb: Add a comment for last change
29494 * einfo.ads: Minor spelling correction in comment
29496 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
29498 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
29501 * sem_util.ads: Minor comment update
29503 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29505 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
29506 Inline_Always when in Configurable_Run_Time mode.
29508 * sem_prag.adb (Process_Convention): If entity is an inherited
29509 subprogram, apply convention to parent subprogram if in same scope.
29510 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
29511 when in Configurable_Run_Time mode.
29513 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29515 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
29516 class_wide type after component list has been inherited.
29518 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29520 * sem_ch12.adb (Check_Generic_Actuals): New predicate
29521 Denotes_Previous_Actual, to handle properly the case of a private
29522 actual that is also the component type of a subsequent array actual.
29523 The visibility status of the first actual is not affected when the
29524 second is installed.
29525 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
29526 make fully recursive the treatment of formals of packages declared
29528 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
29529 the above on exit from an instantiation.
29530 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
29531 current instantiation which is now complete.
29532 (Analyze_Package_Instantiation): No instantiated body is needed if the
29533 main unit is generic. Efficient, and avoid anomalies when a instance
29534 appears in a package accessed through rtsfind.
29536 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29538 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
29539 do not generate a declaration for a temporary if the call is part of a
29540 library-level instantiation.
29542 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29544 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
29545 searching for a limited component to flag.
29547 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
29548 expansion of Input, to account for the fact that the implicit call
29549 generated by the attribute reference must freeze the user-defined
29550 stream subprogram. This is only relevant to 'Input, because it can
29551 appear in an object declaration, prior to the body of the subprogram.
29553 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
29554 expansion can proceed and further errors uncovered.
29555 (Minor clean up): Fix cases of using | instead of \ for continuation
29558 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
29560 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
29562 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
29563 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
29564 Use gcc_assert and gcc_unreachable.
29566 * decl.c (gnat_to_gnu_entity, case object): Check and process a
29567 specified alignment before validating size.
29568 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
29569 stripped-down declaration for the type of the inner field when making
29572 * utils.c (finish_record_type): Do not compute the size in units
29573 incrementally. Instead compute it once for the rep clause case.
29574 Use gcc_assert and gcc_unreachable.
29576 2004-10-04 Vincent Celier <celier@gnat.com>
29578 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
29580 (Is_Valid_Path_Name): Take '/' as a directory separator.
29582 2004-10-04 Vincent Celier <celier@gnat.com>
29584 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
29585 (Extended_Project) only if Extended_Project is defined, to avoid
29587 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
29589 (Parse_Single_Project): Ditto.
29591 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
29592 Add_To_Project_Path for virtual projects.
29594 2004-10-04 Vincent Celier <celier@gnat.com>
29596 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29597 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29598 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
29599 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
29600 parameter Options_2.
29602 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
29603 Build_Dynamic_Library with an empty Options_2.
29605 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
29608 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
29609 directory separator, if any.
29610 (Gprmake): Do not allow mains on the command line for library projects.
29611 Do not attempt to link when the project is a library project.
29612 (Library_Opts): New table to store Library_Options.
29613 (Build_Library): If Library_Options is specified, pass these options
29614 when building a shared library.
29616 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
29618 * s-tposen.adb (Service_Entry): The object must be always unlocked at
29619 the end of this procedure now that the unlock operation was inserted
29622 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
29624 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
29625 corresponding to the Preallocated_Stacks flags in System.
29626 (Get_Target_Parameters): Including the processing for
29627 Preallocated_Stacks.
29629 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
29630 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

29637 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
29638 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
29639 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
29640 used to signal whether the compiler creates the required stacks and
29641 descriptors for the different tasks (when True) or it is done by the
29642 underlying operating system at run time (when False).
29643 It is initially set to False in all targets.
29645 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
29646 if it is supported by the target.
29647 (Make_Task_Create_Call): Pass the stack address if it has been
29648 previously created. Otherwise pass a Null_Address.
29650 * snames.adb: Add _stack.
29652 * snames.ads: Add Name_uStack. Required to allow the expander to
29653 statically allocated task stacks.
29655 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
29656 Stack_Address argument.
29657 Check that its value is equal to Null_Address because this target does
29658 not support the static stack allocation.
29660 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29662 * usage.adb: Change "pragma inline" to "pragma Inline" in information
29665 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29667 * exp_dist.adb: Split declaration of asynchronous flag out of
29668 Add_RACW_Read_Attribute.
29669 Minor reformatting for better alignment with PolyORB version.
29670 Store the entity for the asynchronous flag of an RACW, rather than the
29671 expression, in the asynchronous flags table. This will allow this flag
29672 to be used in other subprograms beside Add_RACW_Read_Attribute.
29674 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29676 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
29677 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
29678 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
29679 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
29680 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
29681 sockets constant MSG_NOSIGNAL (Linux-specific).
29682 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
29683 all Send operations.
29684 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
29685 from trigerring SIGPIPE.
29686 Rename components to avoid clash with Ada 2005 possible reserved
29688 (Check_Selector): When the select system call returns with an error
29689 condition, propagate Socket_Error to the caller.
29691 2004-10-01 Jan Hubicka <jh@suse.cz>
29693 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
29695 2004-09-23 Robert Dewar <dewar@gnat.com>
29698 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
29699 instead do this at freeze time (we won't do it if there is an address
29701 Change "pragma inline" to "pragma Inline" in information and error
29703 Minor reformatting.
29705 * freeze.adb (Check_Address_Clause): Remove previous change, not the
29706 right way of doing things after all.
29707 (Freeze_Entity): For object, set Is_Public for imported entities
29708 unless there is an address clause present.
29710 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
29712 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
29713 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
29714 ensures proper handling of types with rep clauses, which might have
29715 their TYPE_SIZE set already.
29717 2004-09-21 Robert Dewar <dewar@gnat.com>
29719 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
29720 packed array types in both little- and big-endian cases. This change
29721 ensures that we no longer count on the unused bits being initialized
29722 for such types (and in particular ensures that equality testing will
29723 only read the relevant bits).
29724 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
29725 These changes mean that we no longer need to initialize small packed
29727 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
29728 optimization to an LJM field as to its parent field.
29730 * ada-tree.h, trans.c, utils.c, utils2.c:
29731 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
29733 2004-09-20 Jan Hubicka <jh@suse.cz>
29735 * utils.c (gnat_finalize): Remove.
29736 (end_subprog_body): Directly call cgraph_finalize_function;
29737 do not lower the nested functions.
29739 2004-09-20 Robert Dewar <dewar@gnat.com>
29742 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
29743 if an address clause is present, since that means that the Import
29746 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
29748 * 5tsystem.ads: Removed, no longer used.
29750 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
29751 Zack Weinberg <zack@codesourcery.com>
29753 * ada-tree.def: Use tree_code_class enumeration constants
29754 instead of code letters.
29755 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
29756 Update for new tree-class enumeration constants.
29758 2004-09-17 Vincent Celier <celier@gnat.com>
29760 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private
29761 capabilities of the general project manager.
29763 2004-09-09 Vincent Celier <celier@gnat.com>
29765 * a-direct.ads: Add pragma Ada_05

29792 (Add_Unknown_Package, Add_Attribute): Moved to new child package
29794 (Attrs, Package_Attributes): Table instantiations moved from the body to
29795 the private part to be accessible from Prj.Attr.PM body.

29855 raise Program_Error if called from a protected operation.
29857 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
29858 the protected action nesting level.
29859 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
29860 protected action nesting level.
29861 (Unlock): When pragma Detect_Blocking is active decrease the protected
29862 action nesting level.
29864 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
29865 Protected_Action_Nesting.
29867 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
29868 Common_ATCB record. It contains the dynamic level of protected action
29869 nesting for each task. It is needed for checking whether potentially
29870 blocking operations are called from protected operations.
29871 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
29872 Detect_Blocking is active or not in the partition.
29874 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

29908 contains the required machinery for handling that.
29910 * sem_util.ads: Change comment associated to procedure
29911 Check_Potentially_Blocking_Operation.
29912 This procedure does not insert a call for raising the exception because
29913 that is currently done by the run time.
29915 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
29917 * init.c: Add the global variable __gl_detect_blocking that indicates
29918 whether pragma Detect_Blocking is active (1) or not (0). Needed for
29919 making the pragma available at run time.
29920 (__gnat_set_globals): Pass and update the detect_blocking parameter.

29925 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
29927 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
29928 DB is found in the ali file. Any unit compiled with pragma
29929 Detect_Blocking active forces its effect in the whole partition.
29931 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
29932 Detect_Blocking is active and delay is called from a protected
29935 * bindgen.adb (Gen_Adainit_Ada): When generating the call to

29949 (Register_Receiving_Stub): Add Subp_Info formal parameter.
29950 Update API in placeholder implemetation of s-parint to reflect changes
29951 in distribution runtime library.
29953 * sem_ch3.adb (Expand_Derived_Record): Rename to
29954 Expand_Record_Extension.
29956 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
29957 primitive operations of potentially distributed object types that have
29958 non-controlling anonymous access formals.
29960 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
29962 New implementation of expansion for remote access-to-subprogram types,
29963 based on the RACW infrastructure.
29964 This version of sem_dist is compatible with PolyORB/DSA as well as
29967 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
29968 Asynchrronous that applies to a remote access-to-subprogram type, mark
29969 the underlying RACW type as asynchronous.
29971 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
29972 __gnat_using_gnu_linker to 1.

29981 * exp_ch3.adb (Expand_Derived_Record): Rename to
29982 Expand_Record_Extension.
29983 (Build_Record_Init_Proc.Build_Assignment): The default expression in
29984 a component declaration must remain attached at that point in the
29985 tree so New_Copy_Tree copies it if the enclosing record type is derived.
29986 It is therefore necessary to take a copy of the expression when building
29987 the corresponding assignment statement in the init proc.
29988 As a side effect, in the case of a derived record type, we now see the
29989 original expression, without any rewriting that could have occurred
29990 during expansion of the ancestor type's init proc, and we do not need
29991 to go back to Original_Node.
29993 * exp_ch3.ads (Expand_Derived_Record): Rename to
29994 Expand_Record_Extension.
29996 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

30001 subprogram. The proxy object is used as the designated object
30002 for RAS values on the same partition (unless All_Calls_Remote applies).
30003 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30004 System.Partition_Interface.Get_Unique_Remote_Pointer.

30009 New implementation of expansion for remote access-to-subprogram types,
30010 based on the RACW infrastructure.
30012 * exp_dist.ads (Copy_Specification): Update comment to note that this
30013 function can copy the specification from either a subprogram
30014 specification or an access-to-subprogram type definition.
30016 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30018 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30019 in an instance, between an explicit subprogram an one inherited from a
30020 type derived from an actual.
30022 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30023 add a polling call if the subprogram is to be inlined by the back-end,
30024 to avoid repeated calls with multiple inlinings.
30026 * checks.adb (Apply_Alignment_Check): If the expression in the address
30027 clause is a call whose name is not a static entity (e.g. a dispatching
30028 call), treat as dynamic.

30032 * g-trasym.ads: Minor reformatting
30034 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

30043 2004-09-09 Pascal Obry <obry@gnat.com>
30045 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30046 enable map file generation. Add the right option to generate the map
30047 file if Map_File is set to True.
30049 * gnatdll.adb (Gen_Map_File): New variable.
30050 (Syntax): Add info about new -m (Map_File) option.

30078 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
30079 of variable length temporaries for function return now that the
30080 back-end and gigi support it.

30157 consistent treatment of entity references contained within the
30158 enclosed procedure call.
30160 2004-09-01 Vincent Celier <celier@gnat.com>
30162 * bindgen.adb: (Set_EA_Last): New procedure

30249 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
30250 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
30251 option and not mdll anymore. Update comment.
30253 2004-08-16 Pascal Obry <obry@gnat.com>
30255 * bld.adb (Put_Include_Project): Properly handle directory separators

32222 2004-06-07 Thomas Quinot <quinot@act-europe.fr>
32224 * bindgen.adb (Set_Unit_Number): Units is an instance of Table, and so
32225 the index of the last element is Units.Last, not Units.Table'Last

32227 storage for the table).
32229 * exp_ch4.adb (Insert_Dereference_Action): Change predicate that
32230 determines whether to generate a call to a checked storage pool

32264 hand side. Warnings are now properly emitted when variables or prefixes
32265 are assigned but not read.
32267 * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
32268 left hand side referenced variables. Private access types do not

32292 interpretations for rewritten right operand.
32293 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

32719 * sem_ch4.adb (Analyze_Selected_Component): If prefix is a protected
32720 subtype, check visible entities in base type.
32722 * exp_ch7.adb (Clean_Simple_Protected_Objects): Do not generate cleanup
32723 actions if the object is a renaming.
32725 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
32726 Check_Formal_Package_Instance, to determine more precisely when the
32727 formal and the actual denote the same entity.
32729 2004-05-14 Javier Miranda <miranda@gnat.com>
32731 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
32733 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
32734 corresponding to a private_with must be removed from visibility; it
32735 will be made visible later, just before we analyze the private part of
32737 (Check_Private_Child_Unit): Allow private_with clauses in public
32739 (Install_Siblings): Make visible the private entities of private-withed
32741 (Install_Withed_Unit): Do not install the private withed unit if we
32742 are compiling a package declaration and the Private_With_OK flag was
32743 not set by the caller. These declarations will be installed later,
32744 just before we analyze the private part of the package.
32746 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
32747 during the evaluation of the expression that initializes the object,
32748 decorate it with the expected type to avoid cascade errors.
32751 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
32752 subprogram we have to install the private_with clauses after its
32753 specification has been analyzed (as documented in AI-262.TXT).
32755 * sem_ch8.adb (Has_Private_With): New function. Determines if the
32756 current compilation unit has a private with on a given entity.
32757 (Find_Direct_Name): Detect the Beaujolais problem described in
32760 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
32761 provides the functionality of the function Is_Ancestor that was
32762 previously available in sem_ch10. It has been renamed to avoid
32765 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
32767 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
32769 * utils.c (build_vms_descriptor): Use SImode pointers.

32927 2004-05-13 Diego Novillo <dnovillo@redhat.com>
32929 Merge from tree-ssa-20020619-branch.
32931 * config-lang.in (boot_language, build_by_default): Set

32948 * 5qsystem.ads: Remove Short_Address subtype declaration. Moved to
32951 * s-auxdec.ads: Add Short_Address subtype (moved here from System).
32953 * Makefile.in: [VMS]: Add translation for 5qauxdec.ads.
32955 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
32956 Fixes undefined symbols in IA64 gnatlib.
32958 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
32960 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
32961 Short_Address). This will be moved to system.auxdec.

32965 * sem_util.adb: Replace test for presence of a node that is always
32966 present with a call to Discard_Node.
32968 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
32969 Analyze on the library unit node after generation of distribution stub
32970 constructs. The call was a no-op because Unit_Node has already been
32971 Analyzed, and the tree fragments for the distribution stubs are
32972 analyzed as they are inserted in Exp_Dist.
32973 Update comment regarding to distribution stubs to reflect that we
32974 do not generate stub in separate files anymore.
32976 * einfo.ads: Clarify the fact that a tagged private type has the
32977 E_Record_Type_With_Private Ekind.
32979 * erroutc.adb: Minor reformatting
32981 * erroutc.ads (Max_Msg_Length): Increase to cover possible larger
32982 values if line length is increased using -gnatyM (noticed during code
32985 * eval_fat.adb: Minor reformatting

32988 2004-05-10 Ed Schonberg <schonberg@gnat.com>
32991 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): If prefix
32992 has been rewritten as an explicit dereference, retrieve type of
32993 original node to check for possibly unconstrained record type.
32995 2004-05-10 Ed Schonberg <schonberg@gnat.com>
32997 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
32998 overriding, use the operation of the parent unconditionally.
33000 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33001 operation when either operand is a literal, to avoid further
33004 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
33005 overridden by a previous explicit declaration, mark the previous entity
33008 * sem_disp.adb (Check_Dispatching_Operation): New predicate
33009 Is_Visibly_Controlled, to determine whether a declaration of a
33010 primitive control operation for a derived type overrides an inherited
33011 one. Add warning if the explicit declaration does not override.
33013 2004-05-10 Vincent Celier <celier@gnat.com>
33015 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
33016 some cases when the sources are no longer present.
33018 * make.adb (Collect_Arguments): Fail if an external source, not part
33019 of any project need to be compiled, when switch -x has not been
33022 * makeusg.adb: Document new switch -x
33024 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
33025 defaulted to False.
33027 * switch-m.adb (Scan_Make_Switches): New switch -x
33029 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
33030 gnatmake switch -x.
33032 * gnat_ugn.texi: Document new gnatmake switch -x
33034 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
33036 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
33038 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
33039 (process_attributes): Likewise.
33041 2004-05-10 Joel Brobecker <brobecker@gnat.com>
33043 * s-inmaop.ads: Fix spelling mistake in one of the comments.
33045 2004-05-10 Robert Dewar <dewar@gnat.com>
33047 * gnat_ugn.texi: Document that for config pragma files, the maximum
33048 line length is always 32767.
33050 * gnat_rm.texi: For pragma Eliminate, note that concatenation of string
33051 literals is now allowed.
33053 * gnat-style.texi: Remove statement about splitting long lines before
33054 an operator rather than after, since we do not follow this rule at all.
33055 Clarify rule (really lack of rule) for spaces around exponentiation
33057 * sem_elim.adb: Allow concatenation of string literals as well as a
33058 single string literal for pragma arguments.
33060 * sem_prag.ads, sem_prag.adb: (Is_Config_Static_String): New function
33062 * a-textio.adb (Terminate_Line): Do not add line feed if nothing
33063 written for append case.
33065 * frontend.adb: Changes to avoid checking max line length in config
33068 * g-os_lib.ads: Minor reformatting
33070 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was
33071 wrong in any case. Instead use standard value. Noticed during code

34142 * sem_prag.adb (Set_Exported): Warn about making static as result of
34143 export only when the export is coming from source. This may be not
34144 be true e.g. on VMS where we expand export pragmas for exception codes
34145 together with imported or exported exceptions, and we don't want the
34146 user to be warned about something he didn't write.
34148 2004-04-08 Thomas Quinot <quinot@act-europe.fr>
34150 * sem_util.adb (Note_Possible_Modification): Reorganize to remove code
34151 duplication between normal entities and those declared as renamings.

34154 * s-fileio.ads (Form): Remove pragma Inline, as we cannot currently
34155 inline functions returning an unconstrained result.

34251 specified radix_digits is greater or equal to machine_mantissa.
34253 2004-04-05 Javier Miranda <miranda@gnat.com>
34255 * par-ch3.adb: Complete documentation of previous change
34256 Correct wrong syntax documentation of the OBJECT_DECLARATION rule

34269 as is done for non-private derived record types.
34271 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
34272 Ada 2005 AI-310: an abstract non-dispatching operation is not a

34276 expression is Null and target type is not an access type (e.g. a

34281 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
34282 statement whose right-hand side is an inlined call, save a copy of the
34283 original assignment subtree to preserve enough consistency for
34284 Analyze_Assignment to proceed.
34286 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
34287 complete assignment subtree which is now unnecessary, as the expansion
34288 of inlined call has been improved to preserve a consistent assignment
34289 tree. Note_Possible_Modification must be called only
34290 after checks have been applied, or else unnecessary checks will
34293 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
34294 of explicit dereferences that do not Come_From_Source:
34295 - be selective on cases where we must go back to the dereferenced
34296 pointer (an assignment to an implicit dereference must not be
34297 recorded as modifying the pointer);
34298 - do not rely on Original_Node being present (Analyze_Assignment
34299 calls Note_Possible_Modification on a copied tree).
34301 * sem_warn.adb (Check_References): When an unset reference to a pointer
34302 that is never assigned is encountered, prefer '<pointer> may be null'
34303 warning over '<pointer> is never assigned a value'.

34372 a string literal, create a temporary for it, constant folding only
34373 handles scalars here.
34375 2004-04-01 Vincent Celier <celier@gnat.com>

34559 2004-03-29 Ed Schonberg <schonberg@gnat.com>
34561 * exp_ch6.adb (Expand_Call): A call to a function declared in the
34562 current unit cannot be inlined if it appears in the body of a withed
34563 unit, to avoid order of elaboration problems in gigi.
34565 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
34566 information for protected (wrapper) operation as well, to simplify gdb
34569 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
34570 protected body, indicate that the entity for the generated spec comes

34612 a classwide type (for which Is_Object_Reference holds), but it can
34613 also be a value conversion for an access-to-classwide type. In the
34614 latter case, there is an implicit dereference, and the original node
34615 for the prefix does not verify Is_Object_Reference.

34695 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
34696 declaration for a child subprogram body that acts as a spec, indicate
34697 that the entity in the declaration needs debugging information.
34699 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
34700 full view if the subtype is created for a constrained record component;
34701 gigi has enough information to construct the record, and there is no
34702 place in the tree for the declaration.
34704 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
34705 serial number for the dummy body that is built for analysis, to avoid
34706 inconsistencies in the generation of internal names when compiling
34709 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
34711 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
34714 2004-03-22 GNAT Script <nobody@gnat.com>
34716 * Make-lang.in: Makefile automatically updated
34718 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

34743 Minor reformatting.
34745 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
34747 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
34748 as regular exception objects and not as mere integers representing the
34749 condition code. The latter approach required some dynamics to mask off
34750 severity bits, which did not fit well into the GCC table based model.
34751 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
34752 exception data objects. We don't it and it would conflict with the other
34753 external symbol we have to generate for such exceptions.
34755 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
34756 the special code for VMS exceptions, since these are now represented
34757 as regular exceptions objects.
34759 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
34761 * decl.c (debug_no_type_hash): Remove.

34765 2004-03-19 Laurent Guerby <laurent@guerby.net>
34767 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
34768 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
34770 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
34772 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.

34792 * adaint.c: Update comments.
34794 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
34795 GNATLIB_SHARED for FreeBSD.
34797 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
34799 * init.c [VxWorks]: Do not fix the stack size for the environment task.
34800 When needed (stack checking) the stack size is retrieved
34801 from the VxWorks kernel.
34803 * Makefile.in: Flag -nostdinc is required when building the run time
34804 for avoiding looking for files in the base compiler.
34805 Add the VxWorks specific version of the package body for
34806 System.Stack_checking.Operations (5zstchop.adb).
34808 * Make-lang.in: Add the object file for
34809 System.Stack_Checking.Operations.

34817 checking from this package to package System.Stack_Checking.Operations.
34818 This way, stack checking operations are only linked in the final
34819 executable when using the -fstack-check flag.
34821 2004-03-18 Doug Rupp <rupp@gnat.com>
34823 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

34833 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
34834 the procedures Add_To_Path_File.
34835 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
34836 making sure that each directory is present only once and, for object
34837 dirs, when a directory already present is added, the duplicate is
34838 removed and the directory is always put as the last in the table.
34839 Write the path files at the end of these accumulations.
34841 * prj-nmsc.adb (Record_Source): Add source file name in hash table
34842 Files_Htable for all sources.
34844 * prj-proc.adb (Process): Remove restrictions between not directly
34845 related extending projects.

34853 parameter Trusted_Mode.
34855 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
34857 * scn.adb (Determine_License): Take into account a degenerated case
34858 when the source contains only comments.
34860 2004-03-18 Ed Schonberg <schonberg@gnat.com>
34862 * sem_warn.adb (Check_References): For a warning on a selected
34863 component that does not come from source, locate an uninitialized
34864 component of the record type to produce a more precise error message.
34866 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
34868 * 3zsoccon.ads: Fix multicast options.
34870 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
34873 2004-03-15 Robert Dewar <dewar@gnat.com>

34876 pragma used for a private type.
34878 * lib-xref.adb (Generate_Reference): Do not generate warning if
34879 reference is in a different unit from the pragma Unreferenced.
34881 * 5vtpopde.adb: Minor reformatting
34882 Fix casing of To_Task_ID
34884 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
34885 flag if we have an unchecked conversion to an access type in the same
34888 2004-03-15 Geert Bosch <bosch@gnat.com>
34890 * a-ngcoty.adb (Modulus): In alternate formula for large real or
34891 imaginary parts, use Double precision throughout.
34893 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
34894 we want to be able to compile run-time with -gnata for testing, but
34895 this may also be instantiated in user code that is compiled with -gnata.
34897 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
34899 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
34900 codes. Having a separate type for this is useful to enforce consistency
34901 throughout the various run-time units.
34902 (Exception_Data): Use Exception_Code for Import_Code.
34904 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of

34907 with the severity bits masked off.
34908 (Register_VMS_Exception): Handle the additional exception data pointer

34912 component, now reflected by an exported accessor.
34913 (is_handled_by): New routine to compute whether the propagated
34914 occurrence matches some handler choice specification. Extracted out of
34915 get_action_description_for, and expanded to take care of the VMS
34917 (get_action_description_for): Use is_handled_by instead of an explicit
34918 complex condition to decide if the current choice at hand catches the
34919 propagated occurrence.
34921 * raise.h (Exception_Code): New type for C.
34923 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
34924 System.Standard_Library.Exception_Code, to allow references from the
34925 pragma import/export expander.
34927 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
34928 New accessors to allow easy access to GNAT exception data
34930 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
34931 redundant Handled_By_Others component, helper for the personality
34932 routine which will now be able to call the appropriate exception data
34935 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
34936 component of Standard_Exception_Type to be the closest possible to
34937 Exception_Code in System.Standard_Library, that we cannot get at this
34938 point. Expand a ??? comment to notify that this type node should
34939 probably be rewritten later on.
34941 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
34942 registration call to include a pointer to the exception object in the
34945 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
34946 instead of int and explicit bitmasks.
34948 2004-03-15 Vincent Celier <celier@gnat.com>
34950 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
34951 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
34953 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
34954 longer needed now that it is in the spec of
34955 System.Tasking.Task_Attributes.
34957 * adaint.h, adaint.c: (__gnat_create_output_file): New function
34959 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
34961 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
34963 * make.adb (Gnatmake): Do not check the executable suffix; it is being
34964 taken care of in Scan_Make_Arg.
34965 (Scan_Make_Arg): Add the executable suffix only if the argument
34966 following -o, in canonical case, does not end with the executable
34967 suffix. When in verbose mode and executable file name does not end
34968 with executable suffix, output the executable name, in canonical case.
34970 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
34971 to avoid warnings when instantiating Ada.Task_Attributes.
34974 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
34975 in the correct order.
34977 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

34982 directory, instead of the Value.
34983 (Find_Source_Dirs): Remove useless code & comments.
34985 2004-03-15 Ed Schonberg <schonberg@gnat.com>
34987 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
34988 tagged type is inherited, and the parent operation is not frozen yet,
34989 force generation of a freeze node for the inherited operation, so the
34990 corresponding dispatch entry is properly initialized.
34991 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
34992 when looking for user-defined equality operation.
34994 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
34995 boolean when locating primitive equality of tagged component.
34997 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

34999 a temporary before expanding assignment into a loop.
35001 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35002 priority in full, to ensure that any expanded subepxressions of it are
35003 elaborated in the scope of the init_proc.
35005 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
35006 after object declaration, skipping over code that may have been
35007 generated for validity checks.
35009 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
35010 discriminants, ignore the known discriminants of its full view, if
35011 any, to check legality.
35013 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
35014 component if type has unknown discriminants.
35015 (Analyze_Private_Extension_Declaration): Discriminant constraint is
35016 null if type has unknown discriminants.
35018 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
35019 for end label when present.
35021 * s-fileio.adb (Open): When called with a C_Stream, use given name for
35022 temporary file, rather than an empty string.
35024 2004-03-15 Ed Falis <falis@gnat.com>
35026 * s-thread.adb: Removed, no longer used.
35028 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

35048 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
35049 Insert_Dereference_Action when rewriting an implicit dereference into
35050 an explicit one, this will be taken care of during expansion of the
35051 explicit dereference.
35052 (Expand_N_Slice): Same. Always do the rewriting, even for the case
35053 of non-packed slices, since the dereference action generated by
35054 expansion of the explicit dereference is needed in any case.
35055 (Expand_N_Selected_Component): When rewriting an implicit dereference,
35056 analyze and resolve the rewritten explicit dereference so it is seen
35058 (Insert_Dereference_Action): This procedure is now called only for the
35059 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
35060 dereferences that do not come from source (including explicit
35061 dereferences resulting from rewriting implicit ones), but do not
35062 recursively insert a check for the dereference nodes contained within
35064 (Insert_Dereference_Action): Clarify and correct comment.

35941 checks for bitfield creation are triggered.
35942 (finish_record_type): During last pass over the fields, clear

36281 * Makefile.in: map 86numaux to a-numaux for x86_64
36283 2004-01-12 Ed Schonberg <schonberg@gnat.com>
36285 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
36286 generated to rename a generic actual, go to the actual itself, the
36287 subtype is not a user-visible entity.
36289 * sem_ch7.adb (Uninstall_Declarations): If an entity in the visible
36290 part is a private subtype, reset the visibility of its full view, if
36291 any, to be consistent.
36294 * sem_ch12.adb (Analyze_Formal_Package): Diagnose properly an attempt
36295 to use a generic package G as a formal package for another generic

36327 2004-01-05 Robert Dewar <dewar@gnat.com>
36329 * 1ssecsta.ads: Default_Secondary_Stack is not a constant since it may
36330 be modified by the binder generated main program if the -D switch is
36333 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
36334 imported functions (since now we expect this to be done for imported
36337 * 5vtaprop.adb: Add several ??? for sections requiring more comments
36338 Minor reformatting throughout
36340 * 5zinit.adb: Minor reformatting
36341 Add 2004 to copyright date
36342 Minor changes to avoid -gnatwa warnings
36343 Correct some instances of using OR instead of OR ELSE (noted while
36344 doing reformatting)
36346 * sprint.adb: Minor updates to avoid -gnatwa warnings
36348 * s-secsta.ads, s-secsta.adb:
36349 (SS_Get_Max): New function to obtain high water mark for ss stack
36350 Default_Secondary_Stack is not a constant since it may be modified by
36351 the binder generated main program if the -D switch is used.
36353 * switch-b.adb: New -Dnnn switch for binder
36356 Make -gnatg imply all warnings currently in -gnatwa
36358 * vms_conv.adb: Minor reformatting
36359 Add 2004 to copyright notice

36382 lib-xref.adb, sem_ch5.adb, sem_ch7.adb, sem_ch8.adb:
36383 Minor reformatting and code clean ups.
36384 Minor changes to prevent -gnatwa warnings
36386 * ali.adb: Minor reformatting and cleanup of code
36387 Acquire new SS indication of secondary stack use from ali files
36389 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
36390 (since now we expect this to be done for imported functions)
36392 * bindgen.adb: Generate call to modify default secondary stack size if
36395 * bindusg.adb: Add line for new -D switch
36397 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
36398 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
36399 Add circuitry for both records and arrays to avoid gigi
36400 processing if the type involved has non-bit-aligned components
36402 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
36403 N_String_Literal node always references an E_String_Literal_Subtype
36404 entity. This may not be true in the future.
36405 (Possible_Bit_Aligned_Component): Move processing of
36406 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
36408 * exp_ch6.adb (Expand_Thread_Body): Pick up
36409 Default_Secondary_Stack_Size as variable so that we get value modified
36410 by possible -Dnnn binder parameter.
36412 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
36413 (Type_May_Have_Bit_Aligned_Components): New function.
36415 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

36423 importing constant atomic/volatile objects.
36424 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
36425 unless explicit Pure_Function pragma given, to avoid insidious bug of
36426 call to non-pure imported function getting eliminated.

36446 so that it can be modified by the new -Dnnn bind switch.
36448 * rtsfind.adb (Load_Fail): Give full error message in configurable
36449 run-time mode if all_errors mode is set. This was not done in the case
36450 of a file not found, which was an oversight.
36451 Note if secondary stack unit is used by compiler.
36453 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
36454 ineffective elaborate all pragmas on non-visible packages (this
36455 happened when a renamed subprogram was called). Now the elaborate all
36456 always goes on the package containing the renaming rather than the one
36457 containing the renamed subprogram.
36459 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
36460 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
36462 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
36463 has an Etype that references an E_String_Literal.
36464 (Eval_String_Literal): Avoid assumption that N_String_Literal node
36465 always references an E_String_Literal_Subtype entity. This may not
36466 be true in the future.
36468 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
36471 * sem_res.adb (Resolve): Specialize msg for function name used in proc
36474 2004-01-05 Ed Falis <falis@gnat.com>
36476 * g-debuti.adb: Replaced direct boolean operator with short-circuit
36479 2004-01-05 Vincent Celier <celier@gnat.com>
36481 * bld.adb: Minor comment updates
36482 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
36485 * make.adb (Gnatmake): Special process for files to compile/check when
36486 -B is specified. Fail when there are only foreign mains in attribute
36487 Main of the project file and -B is not specified. Do not skip bind/link
36488 steps when -B is specified.
36490 * makeusg.adb: Document new switch -B
36492 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
36494 * switch-m.adb: (Scan_Make_Switches): Process -B switch
36496 * vms_data.ads: Add new GNAT PRETTY qualifier

36501 * trans.c (tree_transform, case N_Free_Statement): Handle thin pointer
36504 * misc.c (gnat_printable_name): If VERBOSITY is 2, call
36505 Set_Identifier_Casing.
36507 * decl.c (gnat_to_gnu_entity, E_Function): Give error if return type
36508 has size that overflows.
36510 2004-01-05 Gary Dismukes <dismukes@gnat.com>
36512 * exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
36513 -gnatwa warning on static condition.
36515 2004-01-05 Doug Rupp <rupp@gnat.com>
36517 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
36519 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
36521 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
36522 all attributes, including read-only attribute.
36524 2004-01-05 Pascal Obry <obry@gnat.com>

36527 library naming scheme.
36529 * mlib-prj.adb (Build_Library): Generate different names for the static
36530 or dynamic version of the GNAT runtime. This is needed to support the
36531 new shared library naming scheme.
36532 (Process_Binder_File): Add detection of shared library in binder file
36533 based on the new naming scheme.
36535 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
36536 scheme for the shared runtime libraries.
36539 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
36541 (install-gnatlib): Do not create symlinks for shared libraries.
36542 (gnatlib-shared-default): Idem.
36543 (gnatlib-shared-dual-win32): New target. Not used for now as the
36544 auto-import feature does not support arrays/records.
36545 (gnatlib-shared-win32): Do not create copy for the shared libraries.
36546 (gnatlib-shared-vms): Fix shared runtime libraries names.
36548 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
36549 dependent runtime shared library name.
36551 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
36553 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
36556 2004-01-05 Ed Schonberg <schonberg@gnat.com>
36558 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
36559 protected objects when allocator has a subtype indication, not a
36560 qualified expression. Note that qualified expressions may have to be
36561 checked when limited aggregates are implemented.
36563 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
36564 pure, emit warning.
36565 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
36566 subprogram is imported, remove warning.
36568 2004-01-05 Geert Bosch <bosch@gnat.com>
36570 * s-poosiz.adb: Update copyright notice.
36571 (Allocate): Use Task_Lock to protect against concurrent access.
36572 (Deallocate): Likewise.
36574 2004-01-05 Joel Brobecker <brobecker@gnat.com>
36576 * s-stalib.adb (Elab_Final_Code): Add missing year in date inside ???

36606 Ada.Exceptions.Last_Chance_Handler.
36608 2003-12-17 Sergey Rybin <rybin@act-europe.fr>
36610 * cstand.adb (Create_Standard): Change the way how the declaration of
36611 the Duration type is created (making it the same way as it is for all
36612 the other standard types).
36614 2003-12-17 Robert Dewar <dewar@gnat.com>
36616 * s-crtl.ads: Fix header format
36617 Change Pure to Preelaborate
36619 2003-12-17 Ed Schonberg <schonberg@gnat.com>
36621 * checks.adb (Selected_Length_Checks): Generate an Itype reference for
36622 the expression type only if it is declared in the current unit.
36624 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
36625 are universal and already analyzed, as can occur in constrained
36626 subcomponents that depend on discriminants, when one constraint is a
36629 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
36630 type Any_Fixed is legal as the argument of a conversion, if only one
36631 fixed-point type is in context.
36633 2003-12-17 GNAT Script <nobody@gnat.com>

36644 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
36645 (Gnatchop): Do not set failure status when reporting the number of
36648 2003-12-15 Doug Rupp <rupp@gnat.com>
36650 * s-ctrl.ads: New file.
36652 * Makefile.rtl (GNAT_RTL_NONTASKING_OBJS): Add s-crtl$(objext).
36654 * Make-lang.in: (GNAT_ADA_OBJS): Add ada/s-crtl.o.
36655 (GNATBIND_OBJS): Add ada/s-crtl.o.
36657 * Makefile.in [VMS]: Clean up ifeq rules.

36670 * Make-lang.in: Makefile automatically updated
36672 2003-12-11 Ed Falis <falis@gnat.com>
36674 * 5zinit.adb: Clean up.
36676 * 5zintman.adb (Notify_Exception): replaced case statement with a call
36677 to __gnat_map_signal, imported from init.c to support
36678 signal -> exception mappings that depend on the vxWorks version.
36681 Created and exported __gnat_map_signal to support signal -> exception
36682 mapping that is dependent on the VxWorks version.

36692 __gnat_handler_installed, as done on all other platforms.
36693 Remove duplicated code.
36695 2003-12-11 Jerome Guitton <guitton@act-europe.fr>
36697 * Makefile.in (rts-zfp, rts-ravenscar): Create libgnat.a.
36699 2003-12-11 Thomas Quinot <quinot@act-europe.fr>
36701 * sinfo.ads: Fix inconsistent example code in comment.
36703 2003-12-11 Robert Dewar <dewar@gnat.com>
36705 * a-tiinau.adb: Add a couple of comments
36707 * sem_ch3.adb: Minor reformatting
36710 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
36711 Minor reformatting throughout
36713 2003-12-11 Ed Schonberg <schonberg@gnat.com>
36715 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
36716 bounds of a loop, create a separate block in order to generate proper
36717 cleanup actions to prevent memory leaks.
36719 * sem_res.adb (Resolve_Call): After a call to
36720 Establish_Transient_Scope, the call may be rewritten and relocated, in
36721 which case no further processing is needed.
36723 * sem_util.adb: (Wrong_Type): Refine previous fix.
36724 Fixes ACATS regressions.
36727 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
36730 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
36732 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
36733 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
36736 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
36739 2003-12-08 Robert Dewar <dewar@gnat.com>
36741 * 7sintman.adb: Minor reformatting
36743 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
36744 standard linker options to get standard libraries linked. We now plan
36745 to provide dummy versions of these libraries to match the appropriate
36746 configurable run-time (e.g. if a library is not needed at all, provide
36747 a dummy empty library).
36749 * targparm.ads: Configurable_Run_Time mode no longer affects linker
36750 options (-L parameters and standard libraries). What we plan to do is
36751 to provide dummy libraries where the libraries are not required.
36753 * gnatbind.adb: Minor comment improvement
36755 2003-12-08 Javier Miranda <miranda@gnat.com>
36757 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
36758 aggregate in the parent. Otherwise constants with limited aggregates
36759 are not supported. Add new formal to pass the component type (Ctype).
36760 It is required to call the corresponding IP subprogram in case of
36761 default initialized components.
36762 (Gen_Assign): In case of default-initialized component, generate a
36763 call to the IP subprogram associated with the component.
36764 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
36765 of aggregate with default initialized components.
36766 (Has_Default_Init_Comps): Improve implementation to recursively check
36767 all the present expressions.
36769 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
36770 to indicate that the initialization call corresponds to a
36771 default-initialized component of an aggregate.
36772 In case of default initialized aggregate with tasks this parameter is
36773 used to generate a null string (this is just a workaround that must be
36774 improved later). In case of discriminants, this parameter is used to
36775 generate a selected component node that gives access to the discriminant
36778 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
36779 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
36780 allocated aggregates with default-initialized components.
36782 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
36783 the box notation is used in positional aggregates.

38523 2003-10-22 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
38525 * tracebak.c (MAX): Avoid redefinition warning.
38527 * init.c [sgi] (__gnat_error_handler): Remove i, unused.
38528 Change msg to const char *.
38529 (__gnat_install_handler): Remove ss, unused.
38530 [sun && __SVR4 && !__vxworks] (__gnat_error_handler): Change msg
38532 * cstreams.c (__gnat_full_name): Declare p only when used.
38533 (__gnat_full_name) [sgi] Return buffer.
38535 2003-10-22 Arnaud Charlet <charlet@act-europe.fr>
38537 * mingw32.h: New file.
38538 * gnat_wrapper.adb: New file.
38540 2003-10-22 Jerome Roussel <roussel@act-europe.fr>
38542 * g-regpat.ads, g-regpat.adb (Match): new function, to know if a
38543 string match a pre compiled regular expression (the corresponding
38544 version of the function working on a raw regular expression)
38545 Fix typos in various comments
38546 Update copyright notice in spec
38548 2003-10-21 Gary Dismukes <dismukes@gnat.com>
38551 (Component_Needs_Simple_Initialization): Return False when the type is a
38552 packed bit array. Revise spec comments to document this case.
38555 (Expand_Pragma_Import): Set any expression on the imported object to
38556 empty to avoid initializing imported objects (in particular this
38557 covers the case of zero-initialization of bit arrays).
38558 Update copyright notice.
38560 2003-10-21 Ed Schonberg <schonberg@gnat.com>
38563 (Load_Parent_Of_Generic): If parent is compilation unit, stop search,
38564 a subunit is missing.
38565 (Instantiate_Subprogram_Body): If body of function is missing, set type
38566 of return expression explicitly in dummy body, to prevent cascaded
38567 errors when a subunit is missing.
38571 (Access_Subprogram_Declaration): Verify that return type is valid.
38575 (Check_Elab_Calls): Do not apply elaboration checks if the main unit is
38580 (Corresponding_Discriminant): If the scope of the discriminant is a
38581 private type without discriminant, use its full view.

40588 (general) Add @./@: where approriate, and two spaces after the
40589 full stop at the end of a sentence. Use @samp markup when
40590 referring concrete lexical entities (keywords, attribute names
40591 etc.), and @syntax for ARM grammar elements. Use @r for English

40606 * make.adb (Add_Switch): Make Generic_Position a procedure. The
40607 function approach did not work well because of a side effect (the
40608 function call could reallocate the table which was being indexed
40609 using its result). Fixes ada/4851.

40668 Add 2001 to copyright date
40670 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
40671 need to force universal inlining for these cases.

40887 When using a project file, fail if specified executable is relative
40888 path with directory information, and prepend executable, if not
40889 specified as an absolute path, with the exec directory. Make sure

40973 there could be a real problem here with an uninitialized reference
40974 to Hbound, but no actual example of failure has been found.
40976 2001-12-17 Laurent Pautet <pautet@gnat.com>
40979 Fix comment of Shutdown_Socket and Close_Socket. These functions
40980 should not fail silently because if they are called twice, this
40981 probably means that there is a race condition in the user program.
40982 Anyway, this behaviour is consistent with the rest of this unit.
40983 When an error occurs, an exception is raised with the error message
40984 as exception message.
40986 2001-12-17 Robert Dewar <dewar@gnat.com>

42318 instead of the previous simple checksum algorithm.
42319 (Time_Stamp_Mismatch): use CRC_Match for comparison.
42320 (Set_Source_Table): idem.
42323 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
42324 instead of simple checksum.
42325 (CRC_Match): new function.
42326 (CRC_Error): new constant.
42328 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
42329 a CRC now and not a simple checksum. A CRC uses lower-case hex
42330 letters, fixes ambiguity in parsing.
42332 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
42333 is what this variable will store.
42335 * bcheck.adb: Change reference to chechsum in comments by CRC.
42336 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
42337 rename All_Checksum_Match to All_CRC_Match. Change due to API
42338 renaming since now GNAT does not use a simple checksum but a
42339 CRC using GNAT.CRC32.
42341 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
42342 now and not anymore a simple checksum.

42381 * types.adb (Hex): Use lowercase for the letter part.
42383 * types.ads (Get_Hex_String): Returns the hexadecimal representation
42384 for a word. This is currently used only for CRC. In previous version,
42385 the checksum was using a representation with all letter being
42386 upper-case. With the new implementation (using CRC) we do not remove
42387 the 32th bit of the CRC, so we can have an upper-case starting letter
42388 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
42389 It is ambigous since the CRC was optional and could be followed by
42390 options like EB, EE. So now this routines uses lower-case letter for
42391 the hexadecimal representation. Strange enough only lower case letters
42392 where checked in Scan_ALI (even if this was not a possible case).
42394 * gnatvsn.ads (Library_Version): changed to 3.15a.
42396 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
42399 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
