3468 reference before the actual is resolved and expanded, to prevent
3469 spurious warnings on formals of enclosing protected operations.

3577 clauses for inherited components of a type extension.
3578 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
3579 an overloadable item if it is a pragma that can apply to multiple
3580 overloadable entities (e.g. Inline) because a pragma cannot be on

3711 subprogram body that acts as its own spec may not have a non-private
3712 WITH clause on a private sibling.
3713 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
3714 child unit is a renaming, create an implicit with_clause on that
3715 parent, and not on the unit it renames, to prevent visibility errors

3819 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
3820 Timed_Entry_Call): Analyze the triggering statement as the first step of
3821 the processing. If this is a dispatching select, postpone the analysis
3822 of all select statements until the Expander transforms the select. This

3824 replicated some of the select statements. In case the Expander is
3825 disabled, perform regular analysis.
3826 (Check_Triggering_Statement): New routine.
3827 (Analyze_Requeue): Exclude any interpretations that are not entries when
3828 checking overloaded names in a requeue. Also test type conformance for

4425 in Xref_Entity_Record, which only supports a single instance of Tref_*,

4444 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
4445 that handles use of 'Access and 'Unchecked_Access applied to

4491 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
4492 used by VxWorks targets to have access to task-specific data and be
4493 able to extract the stack boundaries for stack checking.
4494 Use system-vms-ia64.ads on ivms.
4496 * Make-lang.in: Update dependencies.
4498 * sysdep.c (__gnat_get_stack_info): Move to a standalone file
4501 2007-10-15 Vincent Celier <celier@adacore.com>

4517 Runtime_Library_Dir.
4519 * prj-part.adb (Parse_Single_Project): Do not check the name of the
4520 config project against the user project names.
4522 * prj-proc.adb (Expression): In multi-language mode, indexes that do
4523 not include a dot are always case insensitive.
4524 (Process_Declarative_Items): Ditto
4525 (Process_Project_Tree_Phase_1): Set Success to False in case an error is
4528 * prj-util.adb (Value_Of (In_Array)): When Force_Lower_Case_Index is

4535 2007-10-15 Gary Dismukes <dismukes@adacore.com>
4537 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
4538 association for an access component, add an association with null as
4539 the expression. Remove testing for array subtypes and the setting in
4540 that case of Ctyp to the array component type, which prevented proper
4541 inclusion of an association for null-initialized arrays. Collapse
4542 condition that tests for array subtypes into just a test of
4543 Is_Partially_Initialized_Type (which already covers arrays anyway).
4545 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
4547 * sem_ch12.adb: Minor code reformatting.
4548 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to

4554 * sem_ch3.adb (Build_Derived_Concurrent_Type): Set the Is_Constrained
4555 flag of derived concurrent types, taking into account the flag setting
4556 on the parent subtype and any new set of discriminants.
4558 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
4560 * sem_ch4.adb: Minor code and comment reformatting.
4561 (Analyze_Allocator): When the designated type of an unconstrained
4562 allocator is a record with unknown discriminants or an array with
4563 unknown range bounds, emit a detailed error message depending on the
4564 compilation mode and whether the designated type is limited.
4566 2007-10-15 Tristan Gingold <gingold@adacore.com>
4568 * system-vms-ia64.ads: New file.

4635 * g-soccon-vms.ads: Fix value of MSG_WAITALL.
4638 Update documentation to note that OpenVMS 8.3 or later must be used
4639 to generate g-soccon-vms.ads.
4641 * atree.adb: Add ??? comment
4643 * exp_util.adb: Minor reformatting.

4663 * g-comlin.adb: (Start): Fix handling of empty command line.
4665 * gnatcmd.adb (GNATCmd): Do not put the -rules in the -cargs section,
4666 even when -rules follows the -cargs section.

4684 when compiling for powerpc64-*-linux.
4685 * system-linux-ppc64.ads: New file.
4687 2007-09-27 Eric Botcazou <ebotcazou@adacore.com>
4689 Mapped location support
4690 * back_end.adb (Call_Back_End): Pass information about source
4691 files instead of units to gigi.
4692 * gigi.h (struct File_Info_Type): New.
4693 (gigi): Rename and change type of number_units parameter, change
4694 type of file_info_ptr parameter.
4695 * trans.c (number_files): New global variable.
4696 (gigi): Rename and change type of number_units parameter, change
4697 type of file_info_ptr parameter.
4698 If mapped location support is enabled, create the isomorphic mapping
4699 between source files and line maps.
4700 (Sloc_to_locus): If mapped location support is enabled, translate
4701 source location into mapped location.
4702 (annotate_with_node): Rename into set_expr_location_from_node.
4703 Call set_expr_location instead of annotate_with_locus.
4704 (Pragma_to_gnu): Adjust for above change.

4726 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
4728 * a-calend-vms.adb, a-calend.adb:
4729 Add a section on leap seconds control along with two entities used to
4730 enable and disable leap seconds support. The array Leap_Second_Times is
4731 now constant and contains hard time values pre-generated. Remove
4732 all elaboration code used to populate the table of leap seconds.
4735 Add entity Leap_Seconds_Support to the list of global run-time variables
4736 along with a comment on its usage and values.
4737 (Gen_Adainit_Ada): Add code to generate the declaration and import of
4738 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
4739 or one (enabled) depending on the presence of binder switch "-y".
4740 (Gen_Adainit_C): Add code to generate the declaration of external int
4741 __gl_leap_seconds_support. Set is value to zero (disabled) or one
4742 (enabled) depending on the presence of binder switch "-y".
4744 * init.c: Add __gl_leap_seconds_support to the list of global values
4745 computed by the binder.
4747 2007-09-26 Jerome Guitton <guitton@adacore.com>

4751 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
4752 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
4754 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
4756 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
4757 function which can be called by the debugger to interrupt the tasks of
4758 an Ada application asynchronously, as needed on VxWorks.
4759 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
4761 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
4762 renamed from Stop_All_Tasks. Update comments.
4763 (Stop_All_tasks): New function declaration.
4765 2007-09-26 Olivier Hainque <hainque@adacore.com>
4767 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
4768 #include <utime.h> and #define GCC_RESOURCE_H before

4770 Add more protections in __gnat_translate_vms.
4772 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
4773 #include <sys/wait.h>.
4775 2007-09-26 Thomas Quinot <quinot@adacore.com>
4776 Sergey Rybin <rybin@adacore.com>
4778 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
4780 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
4783 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
4785 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
4788 * sem_dist.ads: Minor comment fix
4790 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
4792 2007-09-26 Javier Miranda <miranda@adacore.com>
4793 Eric Botcazou <ebotcazou@adacore.com>
4796 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
4797 indirection added to the HT_Link component of the TSD. This is required
4798 to statically allocate the TSD.
4801 Minor reordering of the declarations in the private part. Required to
4802 add a level of indirection to the contents of the TSD component HT_Link.
4803 This is required to statically allocate the TSD.
4805 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
4806 Is_Statically_Allocated set from constant objects.
4807 Do not make exported constants created by the compiler volatile.
4808 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
4811 * trans.c (Identifier_to_gnu): For constants, unshare initializers
4812 before returning them.
4814 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
4815 public part of the package.
4816 (Make_DT): Move HT_Link component out of the TSD record. For this
4817 purpose Make_DT now declares a separate object that stores the
4818 HT_Link value, and initializes the TSD component with the address
4819 of this new object. The addition of this level of indirection is
4820 required to statically allocate the TSD because the TSD cannot
4821 have variable components.
4822 (Expand_Interface_Conversion): Improve the expanded code.
4823 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
4825 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
4826 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
4827 if we are building static dispatch tables then we must not generate
4828 extra code to register the primitive because the dispatch table will
4829 be built at the end of the library package; otherwise we notify that
4830 we cannot build the static dispatch table.
4832 2007-09-26 Robert Dewar <dewar@adacore.com>
4834 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
4837 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
4838 (Analyze_Record_Representation_Clause): Suppress junk warning for
4839 missing component clause.

4849 for thunks associated with interface types.
4851 * einfo.ads: Improve documentatation of Is_Internal
4852 (Is_Thunk): New attribute applicable to subprograms. True for thunks
4853 associated with interface types.
4854 Extensive comment fixes regarding flags that appear in all entities. The
4855 documentation is now consistent for all such flags (there were a number
4856 of errors in the documentation in this regard).
4858 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
4860 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
4861 of these procedures are passed a function call that already has
4862 build-in-place actuals (testing new flag
4863 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
4864 the case where processing continues.
4865 (Expand_Call): If the call is generated from a thunk body then we
4866 propagate the extra actuals associated with the accessibility
4867 level of the access type actuals.
4869 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
4870 of each extra formal of a protected operation to reference the
4871 corresponding extra formal of the subprogram denoted by the
4872 operation's Protected_Body_Subprogram.
4874 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
4875 N_Function_Call nodes.
4877 2007-09-26 Robert Dewar <dewar@adacore.com>
4879 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
4881 * debug.adb: Add d.s flag.
4883 2007-09-26 Gary Dismukes <dismukes@adacore.com>
4885 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
4886 debug variable so that it won't be initialized when pragma
4887 Initialize_Scalars is in effect.
4889 2007-09-26 Gary Dismukes <dismukes@adacore.com>
4891 * freeze.adb (Freeze_Entity): Remove check for preelaborable
4892 initialization of a full view. This is moved to
4893 Analyze_Package_Specification.
4895 * sem_ch7.adb (Analyze_Package_Specification): Add check for
4896 preelaborable initialization of a full view in entity loop.
4897 (Uninstall_Declarations): If entity is a use-visible compilation unit,
4898 its child units are use-visible only if they are visible child units.
4900 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
4901 whether an expression can be used within a type declaration that
4902 requires preelaborable init.
4903 (Check_Components): Replace inline code that does partial checking for
4904 preelaborable default expressions with call to
4905 Is_Preelaborable_Expression.
4906 (Has_Preelaborable_Initialization): In the case of a generic actual
4907 subtype, (that is, Is_Generic_Actual is True), return the result of
4908 applying Has_Preelaborable_Initialization to the generic actual's base
4911 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
4913 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
4914 call to Jan_1_Day _Of_Week to optimize its performance.
4915 (Is_Leap): Move the routine to the scope of Week_In_Year.
4916 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
4917 weekday on which January 1 falls of Year - 1 and Year + 1. This function
4918 avoids calling Time_Of and Split, thus making it more efficent.
4919 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
4921 * g-calend.ads (Week_In_Year): Change comment to reflect new
4924 2007-09-26 Emmanuel Briot <briot@adacore.com>
4926 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
4927 Command_Line): New types
4928 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
4929 support for defining how switches can be grouped on a command line (as
4930 is the case for -gnatw... for GNAT), and how simple switches can be
4931 used as aliases for more complex switches (-gnatwa is same as
4933 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
4934 (Start, Current_*): New subprograms
4935 Added support for parsing an array of strings in addition to the real
4937 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
4938 be moved from the body to the private part of the spec.
4939 (*): All subprograms now have an extra parameter with default value to
4940 specify which parser should be used. For backward compatibility, it
4941 defaults to parsing the command line of the application. They were also
4942 modified to properly handle cases where each of the argument does not
4943 start at index 1 (which is always true for Ada.Command_Line, but not
4944 when processing any Argument_List).
4945 (Free): New subprogram
4946 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
4947 Argument): New subprograms
4948 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
4949 special characters like ':', '=',... are now handled in a single place,
4950 which makes the code more extensible eventually.
4951 (Getopt, Full_Switch): When the switch was returned as part of the
4952 special character '*', make sure it is prepended by the switch character
4953 ('-' in general), so that the application knows whether "foo" or "-foo"
4954 was specified on the command line.
4956 2007-09-26 Florian Villoing <villoing@adacore.com>
4958 * g-dirope.adb (Remove_Dir): In case we are removing directories
4959 recursively, make sure that if an exception is raised during the
4960 processing, the current working directory is reset to its initial
4961 value before propagating the exception.
4963 2007-09-26 Vincent Celier <celier@adacore.com>
4965 * gnatbind.adb: If there are several ALI files specified and there is
4966 a main program to bind, the first ALI is expected to contain the main
4967 subprogram and the names of the binder generated files will be derived
4968 from the first ALI file name.
4969 (Gnatbind): Fix insertion character in invocation of Error_Msg
4971 2007-09-26 Vincent Celier <celier@adacore.com>
4973 * gnatcmd.adb (Check_Files): Do not include sources that have been
4974 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
4976 2007-09-26 Ed Schonberg <schonberg@adacore.com>
4978 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
4979 information about each of its index types, following the type
4980 reference for its component type.
4982 2007-09-26 Vincent Celier <celier@adacore.com>
4984 * make.adb: (Kill): New procedure (__gnat_kill imported)
4985 (Running_Compile, Outstanding_Compiles): Global variables that
4986 were previously local to procedure Compile_Sources.
4987 (Sigint_Intercepted): Send signal SIGINT to all outstanding
4988 compilation processes.
4990 (Gnatmake): If project files are used, create the mapping of all the
4991 sources, so that the correct paths will be found.
4993 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
4995 2007-09-26 Vincent Celier <celier@adacore.com>

5350 create an abstract subprogram in the case of 'Input. For 'Output we now
5351 create a real spec/body when the type is abstract, since it can
5352 potentially be called.
5353 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
5354 body for 'Output when the type is abstract (only the creation of the
5355 body for 'Input is excluded when the type is abstract).
5356 (Stream_Operation_OK): Add an additional condition in the return
5357 statement, so that False will be returned for TTS_Stream_Input if the
5358 associated tagged type is an abstract extension. Add comments for
5360 (Expand_N_Object_Declaration): For the case of a shared passive
5361 variable, insert init proc call only after the shared variable
5362 procedures have been processed, because the IP call needs to undergo
5363 shared passive variable reference expansion, which requires these
5364 procedures to be available (and elaborated).

5380 to remove other spurious ambiguities on arithmetic operations involving
5381 literals and addresses, on systems where Address is a visible integer
5382 type, when the operator is called in functional notation.
5383 (Try_Primitive_Operation): Within an instance, a call in prefixed form
5384 is legal when the types match, even if the operation is currently
5387 2007-09-10 Ed Schonberg <schonberg@adacore.com>
5389 * sem_ch12.adb (Build_Local_Package): A formal package with no
5390 associations is legal if all formals have defaults. It is not

5532 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
5533 library-level package renaming, pass the declaration associated with

5538 occurring in the list of entities to qualify, and do not attempt to
5539 traverse an entity list in that case. Variables associated with
5540 ` library-level package renamings can now occur in the table.

5566 avoid very deep recursion in the front end, which was causing stack
5569 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
5570 string, and the right operand is a string literal (the case of "" &
5571 "..."), optimize by avoiding copying the right operand -- just use the
5572 value of the right operand directly.
5574 * stringt.adb (Store_String_Chars): Optimize by growing the
5575 String_Chars table all at once, rather than appending characters one by
5577 (Write_String_Table_Entry): If the string to be printed is very long,
5578 just print the first few characters, followed by the length. Otherwise,
5579 doing "pn(n)" in the debugger can take an extremely long time.
5581 * sem_prag.adb (Process_Interface_Name): Replace loop doing
5582 Store_String_Char with Store_String_Chars.

5601 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
5602 flag, for effiency. It is called when analyzing arithmetic operators
5603 and also for actuals in calls that are universal_integers. The flag is
5604 set for the predefined type address, and for any type or subtype
5607 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
5608 Universal_Integer, when the formal is a descendent of address and the
5609 call appears in user code.

5676 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
5677 associated with Standard_Debug_Renaming_Type, to be used as the type of
5678 the special variables whose names provide debugger encodings for
5679 renaming declarations.
5681 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.

5689 (Debug_Renaming_Declaration): Replace creation of an enumeration type
5690 and literal with creation of a variable of type
5691 Standard_Debug_Renaming_Type whose name encodes both the renamed object
5692 and the entity of the renaming declaration.
5693 (Qualify_Entity_Name): Add the delayed qualification of the entity name
5694 part of the name of a variable that has a Debug_Renaming_Link.

5701 Ed Schonberg <schonberg@adacore.com>
5702 Javier Miranda <miranda@adacore.com>
5704 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
5705 ancestor part given by an aggregate to test for an unchecked conversion,
5706 since this can occur in some cases when the ancestor part is a function
5707 call, and we don't want to fall into the recursive call to this
5708 procedure in that case.
5710 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
5711 stream attributes on limited types to account for user-specified
5712 attributes as well as whether Input (resp. Output) becomes available
5713 due to Read (resp. Write) being available for the type. Change Boolean
5714 variable to the more accurate name
5715 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
5716 double-"not" predicate at beginning of return statement to more
5717 understandable form.
5719 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
5720 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
5721 in a block statement and use that as the first statement of the
5722 expanded return rather than incorrectly using the handled sequence as
5723 the first statement.
5725 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
5726 operation, generate an explicit freeze node for it rather than
5727 generating extra formals, to ensure that gigi has the proper order of
5728 elaboration for anonymous subtypes in the signature of the subprograms.
5729 (Build_In_Place_Formal): Move assertion to beginning of loop.
5730 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
5731 applied to a function call (occurs for some cases of 'Input).
5732 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
5733 applied to a function call (occurs for some cases of 'Input).
5735 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
5736 2005, generate an extended return statement enclosing the result object
5739 * freeze.adb (Freeze_Record_Type): Extend the current management of
5740 components that are access type with an allocator as default value: add
5741 missing support to the use of qualified expressions of the
5742 allocator (which also cause freezing of the designated type!)
5743 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
5744 dispatching operation, since extra formals may be needed by calls to
5745 build-in-place functions (such as stream 'Input).
5747 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
5748 formals for 'Constrained and accessibility level in the case of a
5749 predefined dispatching operation.
5751 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
5752 point, no need to find the parent node.
5754 2007-08-16 Javier Miranda <miranda@adacore.com>
5756 * exp_attr.adb (Attribute_Priority): Add missing support for entries
5759 2007-08-16 Javier Miranda <miranda@adacore.com>
5761 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
5762 is not really required and can introduce regression with the debugger.
5763 The original problem is fixed with the patch written for checks.adb.
5765 2007-08-16 Thomas Quinot <quinot@adacore.com>
5767 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

5775 Including_Non_Switch set to False.
5777 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
5778 parameter Including_Non_Switch, defaulted to True. When
5779 Including_Non_Switch is False, options that are not switches and

5796 (Install_Limited_Withed_Unit): Do not install the limited view of
5797 package P if P is reachable through an ancestor chain from package C
5798 and C also has a with clause for P in its body.
5799 (Has_Limited_With_Clause): New routine.
5800 (Has_With_Clause): New routine.
5802 2007-08-16 Ed Schonberg <schonberg@adacore.com>
5804 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
5805 generic for an enclosing instance is a global reference, even though
5806 its scope is the enclosing instance.
5808 2007-08-16 Gary Dismukes <dismukes@adacore.com>
5809 Javier Miranda <miranda@adacore.com>

5829 Bob Duff <duff@adacore.com>
5830 Nicolas Setton <setton@adacore.com>
5832 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
5833 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
5834 the statement which is being resolved comes from a predefined library
5835 unit, all non-predefined library interpretations are skipped.
5836 (Resolve_Op_Concat): If string concatenation was folded in the parser,
5837 but the "&" is user defined, give an error, because the folding would
5840 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
5841 the parser has folded a long sequence of concatenations of string
5844 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
5845 and "JMP_BUF" variables as artificial.
5846 (N_String_Literal): Do not use alloca for very long string literals. Use

5900 needed for access to concurrent record types generated by the expander.
5901 (Generate_Range_Check): When generating a temporary to capture the
5902 value of a conversion that requires a range check, set the type of the
5903 temporary before rewriting the node, so that the type is always
5904 properly placed for back-end use.
5905 (Apply_Float_Conversion_Check): Handle case where the conversion is

5915 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
5916 a-stwisu.adb, a-strsup.adb: Fix warnings for range
5917 tests optimized out.
5919 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
5920 (Get_Allocator_Final_List): For the case of an anonymous access type
5921 that has a specified Associated_Final_Chain, do not go up to the
5923 (Expand_N_Type_Conversion): Test for the case of renamings of access
5924 parameters when deciding whether to apply a run-time accessibility
5926 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
5927 aggregate code before allocator, and ahead of declaration for
5928 temporary, to prevent access before elaboration when the allocator is
5929 an actual for an access parameter.
5930 (Expand_N_Type_Conversion): On an access type conversion involving an
5931 access parameter, do not apply an accessibility check when the
5932 operand's original node was an attribute other than 'Access. We now
5933 create access conversions for the expansion of 'Unchecked_Access and
5934 'Unrestricted_Access in certain cases and clearly accessibility should
5935 not be checked for those.
5937 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
5938 includes a type conversion of a packed component that has been expanded,
5939 recover the original expression for the object, and use this expression
5940 in the post-call assignment statement, so that the assignment is made
5941 to the object and not to a back-end temporary.
5942 (Freeze_Subprogram): In case of primitives of tagged types not defined
5943 at the library level force generation of code to register the primitive
5944 in the dispatch table. In addition some code reorganization has been
5945 done to leave the implementation clear.
5946 (Expand_Call): When expanding an inherited implicit conversion,
5947 preserve the type of the inherited function after the intrinsic
5948 operation has been expanded.
5950 * exp_ch2.ads, exp_ch2.adb
5951 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
5952 of an entry formal appearing in an assignment statement does not assign
5954 (Expand_Current_Value): Instead of calling a routine to determine
5955 whether the prefix of an attribute reference should be optimized or
5956 not, prevent the optimization of such prefixes all together.
5958 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
5959 component whose prefix is known to be of an access type is an implicit
5960 dereference and does not assign to the prefix.
5962 2007-08-14 Ed Schonberg <schonberg@adacore.com>
5963 Robert Dewar <dewar@adacore.com>
5965 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
5966 itype is visited, make an entry into table to link associated node and
5968 Add comments and correct harmless error in Build_NCT_Hash_Tables
5969 (Array_Aggr_Subtype): Associate each itype created for an index type to
5970 the corresponding range construct, and not to the aggregate itself. to
5971 maintain a one-to-one correspondence between itype and its associated
5972 node, to prevent errors when complex expression is copied.
5973 Fix mishandling of multiple levels of parens
5975 * sem_aggr.adb: Create a limited view of an incomplete type, to make
5976 treatment of limited views uniform for all visible declarations in a
5977 limited_withed package.
5978 (New_Copy_Tree): If hash table is being used and itype is visited,
5979 make an entry into table to link associated node and new itype.
5980 (Resolve_Record_Aggregate): Do not add an others box association for a
5981 discriminated record component that has only discriminants, when there
5982 is a box association for the component itself.
5984 * par-ch4.adb: Fix mishandling of multiple levels of parens
5986 2007-08-14 Robert Dewar <dewar@adacore.com>

6018 Robert Dewar <dewar@adacore.com>
6019 Javier Miranda <miranda@adacore.com>
6020 Gary Dismukes <dismukes@adacore.com>
6022 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
6023 to make treatment of limited views uniform for all visible declarations
6024 in a limited_withed package.
6025 Improve warnings for in out parameters
6026 (Set_Related_Interaface/Related_Interface): Allow the use of this
6027 attribute with constants.
6028 (Write_Field26_Name): Handle attribute Related_Interface in constants.
6029 Warn on duplicate pragma Preelaborable_Initialialization
6031 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
6032 generation of a freezing node to ensure proper management of null
6033 excluding access types in the backend.
6034 (Create_Extra_Formals): Test base type of the formal when checking for
6035 the need to add an extra accessibility-level formal. Pass the entity E
6036 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
6037 originally being done in a couple of cases), to ensure that the
6038 Extra_Formals list gets set on the entity E when the first entity is
6040 (Conforming_Types): Add missing calls to Base_Type to the code that
6041 handles anonymous access types. This is required to handle the
6042 general case because Process_Formals builds internal subtype entities
6043 to handle null-excluding access types.
6044 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
6045 functions that need it, even when not marked Requires_Overriding.
6046 Improve warnings for in out parameters
6047 (Analyze_Function_Return): Warn for disallowed null return
6048 Warn on return from procedure with unset out parameter
6049 Ensure consistent use of # in error messages
6050 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
6051 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
6052 the implicit conversion of the expression done for anonymous access
6053 types. This is required to generate the code of the null excluding
6054 check (if required).
6056 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
6057 A formal parameter is never publicly referenceable outside of its body.
6058 (Check_References): For an unreferenced formal parameter in an accept
6059 statement, use the same warning circuitry as for subprogram formal
6061 (Warn_On_Unreferenced_Entity): New subprogram, taken from
6062 Output_Unreferenced_Messages, containing the part of that routine that
6063 is now reused for entry formals as described above.
6064 (Goto_Spec_Entity): New function
6065 (Check_References): Do not give IN OUT warning for dispatching operation
6066 Improve warnings for in out parameters
6067 (Test_Ref): Check that the entity is not undefinite before calling
6068 Scope_Within, in order to avoid infinite loops.
6069 Warn on return from procedure with unset out parameter
6070 Improved warnings for unused variables
6072 2007-08-14 Robert Dewar <dewar@adacore.com>
6073 Javier Miranda <miranda@adacore.com>
6074 Gary Dismukes <dismukes@adacore.com>
6076 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
6077 (Expand_N_Attribute_Reference): Further unify the handling of the
6078 three forms of access attributes, using common code now for all three
6079 cases. Add a test for the case of applying an access attribute to
6080 an explicit dereference when the context is an access-to-interface
6081 type. In that case we need to apply the conversion to the prefix
6082 of the explicit dereference rather than the prefix of the attribute.
6083 (Attribute_Version, UET_Address): Set entity as internal to ensure
6084 proper dg output of implicit importation.
6085 (Expand_Access_To_Type): Removed.
6086 (Expand_N_Attribute_Reference): Merge the code from the three cases
6087 of access attributes, since the processing is largely identical for
6088 these cases. The substantive fix here is to process the case of a
6089 type name prefix (current instance case) before handling the case
6090 of interface prefixes.
6092 2007-08-14 Thomas Quinot <quinot@adacore.com>
6093 Ed Schonberg <schonberg@adacore.com>
6094 Javier Miranda <miranda@adacore.com>
6095 Robert Dewar <dewar@adacore.com>
6097 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
6098 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
6099 type that is an anonymous access to controlled object, establish
6100 an associated finalization chain to avoid corrupting the global
6101 finalization list when a dynamically allocated object designated
6102 by such a component is deallocated.
6103 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
6104 functions that need it, even when not marked Requires_Overriding.
6105 (Initialize_Tag): Replace call to has_discriminants by call to
6106 Is_Variable_Size_Record in the circuitry that handles the
6107 initialization of secondary tags.
6108 (Is_Variable_Size_Record): New implementation.
6109 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
6110 Suppress_Initialization pragma for a derived type.
6111 (Is_Variable_Size_Record): New subprogram.
6112 (Build_Offset_To_Top_Functions): New implementation that simplifies the
6113 initial version of this routine and also fixes problems causing
6114 incomplete initialization of the table of interfaces.
6115 (Build_Init_Procedure): Improve the generation of code to initialize the
6116 the tag components of secondary dispatch tables.
6117 (Init_Secondary_Tags): New implementation that simplifies the previous
6118 version of this routine.
6119 (Make_DT): Add parameter to indicate when type has been frozen by an
6120 object declaration, for diagnostic purposes.
6121 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
6122 diagnose attemps to freeze a subprogram when some untagged type of its
6123 profile is a private type whose full view has not been analyzed yet.
6124 (Freeze_Array_Type): Generate init proc for packed array if either
6125 Initialize or Normalize_Scalars is set.
6126 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
6127 constructing the new profile, copy the null_exclusion indicator for each
6128 parameter, to ensure full conformance of the new body with the spec.
6130 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
6131 Create wrappers for constructor functions that need it, even when not
6132 marked Requires_Overriding.
6133 (Covers): Handle properly designated types of anonymous access types,
6134 whose non-limited views are themselves incomplete types.
6135 (Add_Entry): Use an entity to store the abstract operation which hides
6137 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
6138 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
6139 initialization aggregate.
6140 (Function_Interp_May_Be_Hidden): Rename to
6141 Function_Interp_Has_Abstract_Op.
6142 (Has_Compatible_Type): Remove machinery that skips interpretations if
6143 they are labeled as potentially hidden by an abstract operator.
6144 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
6145 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
6146 (Write_Overloads): Output the abstract operator if present.
6147 (Add_Entry): Before inserting a new entry into the interpretation table
6148 for a node, determine whether the entry will be disabled by an abstract
6150 (Binary_Op_Interp_May_Be_Hidden): New routine.
6151 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
6153 (Function_Interp_May_Be_Hidden): New routine.
6154 (Has_Compatible_Type): Do not consider interpretations hidden by
6155 abstract operators when trying to determine whether two types are
6157 (Has_Hidden_Interp): New routine.
6158 (Set_May_Be_Hidden_Interp): New routine.
6159 (Write_Overloads): Write the status of flag May_Be_Hidden.
6161 2007-08-14 Ed Schonberg <schonberg@adacore.com>
6162 Javier Miranda <miranda@adacore.com>
6164 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
6165 types declared in the declarative part of a nested package body or in
6166 the proper body of a stub.
6167 (Set_All_DT_Position): Add missing check to avoid wrong assignation
6168 of the same dispatch table slot to renamed primitives.
6169 (Make_Select_Specific_Data_Table): Handle private types.
6170 (Tagged_Kind): Handle private types.
6171 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
6172 output of implicit importation and exportation.
6173 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
6174 first formal of the thunk is always associated with the controlling
6175 type. In addition perform the following code cleanup: remove formal
6176 Thunk_Alias which is no longer required, cleanup evaluation of the
6177 the controlling type, and update the documentation.
6178 Replace occurrence of Default_Prim_Op_Count by
6179 Max_Predef_Prims. Addition of compile-time check to verify
6180 that the value of Max_Predef_Prims is correct.
6181 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
6182 (Make_DT): Add parameter to indicate when type has been frozen by an
6183 object declaration, for diagnostic purposes.
6184 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
6185 construction of statically allocated dispatch tables.
6186 (Make_DT): In case of library-level tagged types export the declaration
6187 of the primary tag. Remove generation of tags (now done by Make_Tags).
6188 Additional modifications to handle non-static generation of dispatch
6189 tables. Take care of building tables for asynchronous interface types
6190 (Make_Tags): New subprogram that generates the entities associated with
6191 the primary and secondary tags of Typ and fills the contents of Access_
6192 Disp_Table. In case of library-level tagged types imports the forward
6193 declaration of the primary tag that will be declared later by Make_DT.
6194 (Expand_Interface_Conversion): In case of access types to interfaces
6195 replace an itype declaration by an explicit type declaration to avoid
6196 problems associated with the scope of such itype in transient blocks.
6198 2007-08-14 Robert Dewar <dewar@adacore.com>
6199 Ed Schonberg <schonberg@adacore.com>
6200 Javier Miranda <miranda@adacore.com>
6202 * exp_util.ads, exp_util.adb:
6203 This patch replaces a number of occurrences of explicit tests for N_Null
6204 with calls to Known_Null. This improves tracking of null values, since
6205 Known_Null also catches null constants, and variables currently known to
6206 be null, so we get better tracking.
6207 (Ensure_Defined): create an itype reference only in the scope of the
6209 (Side_Effect_Free): A selected component of an access type that
6210 denotes a component with a rep clause must be treated as not
6211 side-effect free, because if it is part of a linked structure its
6212 value may be affected by a renaming.
6213 (Expand_Subtype_From_Expr): For limited objects initialized with build
6214 in place function calls, do nothing; otherwise we prematurely introduce
6215 an N_Reference node in the expression initializing the object, which
6216 breaks the circuitry that detects and adds the additional arguments to
6217 the called function. Bug found working in the new patch for statically
6218 allocated dispatch tables.
6219 (Is_Library_Level_Tagged_Type): New subprogram.
6220 (Remove_Side_Effects): If the expression of an elementary type is an
6221 operator treat as a function call.
6222 (Make_Literal_Range): If the index type of the array is not integer, use
6223 attributes properly to compute the constraint on the resulting aggregate
6226 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
6227 class-wide type whose base type is an incomplete private type, leave
6228 class-wide type unfrozen so that freeze nodes can be generated
6229 properly at a later point.
6230 (Freeze_Entity, array case): Handle case of pragma Pack and component
6231 size attributre clause for same array.
6233 2007-08-14 Vincent Celier <celier@adacore.com>

6288 attribute Body in package Naming. Do not replace a source/unit in the
6289 same project when the order of the source dirs are known. Detect
6290 duplicate sources/units in the same project when the order of the
6291 source dirs are not known.
6292 (Check_Ada_Name): Allow all identifiers that are not reserved words
6294 Major update of the Project Manager and of the project aware tools,
6295 including gprmake, so that the same sources in the GNAT repository
6296 can be used by gprbuild.

6298 directory of non extending project to nil.
6299 Change type of path name variables to be Path_Name_Type
6300 (Locate_Directory): Make sure that on Windows '/' is converted to '\',
6301 otherwise creating missing directories will fail.

6886 takes progenitor types into account.
6887 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
6888 traversing over the primitives of the formal and actual types to locate
6889 any abstract subprograms of the actual type that correspond to a
6890 nonabstract subprogram of the formal type's ancestor type(s), and issue
6891 an error if such is found.

6907 an access_to_constant type.
6908 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
6909 type, the candidate operations are found in the scope of declaration of
6910 the type, because the type has no primitive subprograms.
6911 (Analyze_Selected_Component): If prefix is class-wide, and root type is
6912 a private extension, only examine visible components before trying to
6913 analyze as a prefixed call.

6928 purpose of enforcing E.2.2(8) only if it is not available at any place.
6929 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
6930 when checking the legality of an extension aggregate in a preelaborable
6931 package. Treat the literal null as a valid default expression in a
6932 component declaration for a type with preelaborable initialization.
6933 A limited interface is a legal progenitor for the designated type of a
6934 remote access to class-wide type.

6966 do not consider those that are hidden by abstract operators.
6967 (Resolve_Actuals): When verifying that an access to class-wide object
6968 is an actual for a controlling formal, ignore anonymous access to
6969 subprograms whose return type is an access to class_wide type.
6970 (Resolve_Slice): If the prefix of the slice is a selected component
6971 whose type depends on discriminants, build its actual subtype before
6972 applying range checks on the bounds of the slice.

8179 overloading cases, when several ancestors may have class-wide operations
8180 that are possible candidates, and when the overloaded functions return

8182 interpreted as an indexing.

8190 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
8191 perform homonym traversal, looking for class-wide operation matches

8201 aliased when the corresponding controlling formal is an access
8203 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
8204 ambiguous calls in prefixed notation, where two primitives differ only
8205 in that the controlling argument of one is an access parameter.

8215 interface change the type of all controlling formals to that of the

8218 to determine the tagged type to which a primitive belongs.

8225 controlling result when determining whether to add a BIP_Alloc_Form
8226 formal and a BIP_Final_List formal to the function.
8227 (Check_Conformance); For parameters that are anonymous access types,
8228 subtype conformance requires that the not null and the constant
8229 indicators must match
8230 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
8231 to retrieve the appropriate type when processing a concurrent type
8232 declared within a generic. Minor comment reformatting. Change invocation
8233 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
8235 (Analyze_Subprogram_Body): If the return type of a function is an
8236 anonymous access to the limited view of a class-wide type, and the
8237 non-limited view of the type is available, update the type of the
8238 function so that code can be generated.
8239 (Process_Formals): In case of access-subtype itype whose designated
8240 type is also an itype (situation that happens now with access to
8241 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
8242 attribute to avoid backend problems.
8243 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
8244 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
8245 anonymous types' designated types are same before testing
8246 Subtypes_Statically_Match.
8247 (Create_Extra_Formals): Test for a named access parameter that is a
8248 controlling formal as an additional condition for adding an
8249 accessibility level formal. This can occur in the subp type created for
8250 dispatching calls in Expand_Dispatching_Call, and allows calling
8251 Create_Extra_Formals from that procedure rather than special-casing the
8252 extra formals there.
8253 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
8254 when the function has a controlling result.
8255 (Check_Returns): Add much more knowledge of the optimization of local
8256 raise statements to gotos, to retain proper warnings in this case.
8257 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
8258 nodes when looking for last statement.
8260 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
8261 class-wide types visible through limited with clauses.
8262 (Add_One_Interp): If the operands are anonymous access types, the
8263 predefined operator on universal_access is immediately visibles
8264 (Find_Unique_Type): Handle anonymous access to subprogram types just as
8265 other anonymous access types.
8266 (Disambiguate): Take into account CIL convention.
8267 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
8269 2007-06-06 Robert Dewar <dewar@adacore.com>
8271 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
8272 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
8273 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
8274 Fix lower bound of tables.
8277 * nlists.adb: Ditto.
8278 (Prev_Node, Next_Node): Change index type to Int so that it properly
8279 covers the range First_Node_Id - 1 up.
8281 2007-06-06 Javier Miranda <miranda@adacore.com>
8282 Ed Schonberg <schonberg@adacore.com>
8283 Bob Duff <duff@adacore.com>
8284 Hristian Kirtchev <kirtchev@adacore.com>
8286 * exp_aggr.ads, exp_aggr.adb:
8287 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
8288 in extension aggregates.
8289 (Flatten): Other conditions being met, an aggregate is static if the
8290 low bound given by component associations is different from the low
8291 bound of the base index type.
8292 (Packed_Array_Aggregate_Handled): If the component type is itself a
8293 packed array or record, the front-end must expand into assignments.
8294 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
8295 Init_Pr, instead of Ancestor_Is_Expression.
8296 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
8297 coextension chain root, either generate a list controller or use the
8298 already existing one.
8299 (Static_Array_Aggregate): New procedure to construct a positional
8300 aggregate that can be handled by the backend, when all bounds and
8301 components are compile-time known constants.
8302 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
8303 types covering interface types into assignments.
8304 (Replace_Type): move to Build_Record_Aggr_Code.
8305 (Expand_Record_Aggr_Code): if the target of the aggregate is an
8306 interface type, convert to the definite type of the aggregate itself,
8307 so that needed components are visible.
8308 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
8309 components and the context is an extended return statement do not
8310 create a transient block for it, to prevent premature finalization
8311 before the return is executed.
8312 (Gen_Assign): Do not generate a call to deep adjust routine if the
8313 component type is itself an array of controlled (sub)-components
8314 initialized with an inner aggregate.
8315 (Component_Check): New name for Static_Check. This name is now more
8316 appropriate, and documentation is added which was missing.
8317 (Component_Check): Add test for bit aligned component value
8318 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
8319 Tagged_Comps, name is more appropriate given added function below.
8320 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
8322 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
8323 Javier Miranda <miranda@adacore.com>
8324 Robert Dewar <dewar@adacore.com>
8326 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
8327 Terminated: Add unchecked type conversion from System.Address to
8328 System.Tasking.Task_Id when calling the predefined primitive
8330 Disable new Ada 05 accessibility check for JVM.NET targets, which
8331 cannot be implemented in a practical way.
8332 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
8333 the sources always references the tag of the actual object. Therefore,
8334 if 'Tag is applied in the sources to class-wide interface objects we
8335 generate code that displaces "this" to reference the base of the object.
8336 (Expand_N_Attribute_Reference, case Size): Return specified size if
8338 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
8339 has code that displaces the pointer of the object to manage interface
8340 types. However this code must not be executed when the prefix is a
8341 subprogram. This bug caused the wrong expansion of the internally
8342 generated assignment that fills the dispatch table when the primitive
8343 is a function returning a class-wide interface type.
8344 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
8345 Set_Attribute_Name for Name_Unaligned_Valid.
8347 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8348 Gary Dismukes <dismukes@adacore.com>
8350 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
8351 If the initialization is the equivalent aggregate of the initialization
8352 procedure of the type, do not remove it.
8353 (Expand_N_Attribute_Definition_Clause): Exclude access variables
8354 initialized to null from having their expression reset to empty and
8355 note this exception in the comment.
8357 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
8358 Robert Dewar <dewar@adacore.com>
8359 Ed Schonberg <schonberg@adacore.com>
8360 Gary Dismukes <dismukes@adacore.com>
8362 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
8363 Add "with" and "use" clauses for Sem_Attr.
8364 (Expand_Current_Value): Do not replace occurences of attribute
8365 references where the prefix must be a simple name.
8367 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
8368 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
8369 Attribute_Requires_Simple_Name_Prefix.
8370 (Name_Modifies_Prefix): Body of new function.
8371 (Requires_Simple_Name_Prefix): Body of new function.
8372 (Resolve_Attribute, case Access): Improve error message for case of
8373 mismatched conventions.
8374 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
8376 (Analyze_Attribute, case 'Access): If the type of the prefix is a
8377 constrained subtype for a nominal unconstrained type, use its base type
8378 to check for conformance with the context.
8379 (Resolve_Attribute): Remove test of the access type being associated
8380 with a return statement from condition for performing accessibility
8381 checks on access attributes, since this case is now captured by
8382 Is_Local_Anonymous_Access.
8383 (Analyze_Access_Attribute): Set Address_Taken on entity
8384 (Analyze_Attribute, case Address): Set Address_Taken on entity
8385 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
8386 validating an access attribute whose prefix is a current instance.
8387 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
8388 applied to dispatching operations, if freezing is required then we set
8389 the attribute Has_Delayed_Freeze in the prefix's entity.
8390 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
8391 current scope if access of local subprogram taken
8392 (Analyze_Access_Attribute): Check legality of self-reference even if the
8393 expression comes from source, as when a single component association in
8394 an aggregate has a box association.
8395 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
8396 the prefix if it is a protected operation and the attribute is
8397 Unrestricted_Access.
8398 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
8399 reference to the base type of the context, to force a constraint check
8400 when the context is an access subtype with an explicit constraint.
8401 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
8402 node is rewritten as an interface conversion. leave unanalyzed after
8403 resolution, to ensure that type checking against the context will take
8406 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8407 Javier Miranda <miranda@adacore.com>
8408 Robert Dewar <dewar@adacore.com>
8410 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
8411 wrapper when the full view of the controlling type of an inherited
8412 function that dispatches on result implements interfaces.
8413 (Expand_N_Object_Declaration): In cases where the type of the
8414 declaration is anonymous access, create finalization list for it.
8415 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
8416 if the object has no explicit initialization, to match description of
8417 functionality of pragam Persistent_BSS.
8418 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
8419 new function to build static aggregates, to replace initialization call
8420 when static initialization is desired.
8421 (Freeze_Type): Generate a list controller for an access type whenever
8422 its designated type has controlled anonymous access discriminants.
8423 (Build_Equivalent_Aggregate): New procedure to compute a static
8424 aggregate to be used as default initialization for composite types,
8425 instead of a generating a call to the initialization procedure for the
8427 (Build_Initialization_Call): When available, replace a call to the
8428 initialization procedure with a copy of the equivalent static aggregate
8430 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
8431 declarations for objects of a class-wide interface type, rather than
8432 just identifiers, to prevent visibility problems.
8433 (Expand_N_Object_Declaration): When expanding the declaration for an
8434 object of a class-wide interface type, preserve the homonym chain of
8435 the original entity before exchanging it with that of the generated
8436 renaming declaration.
8437 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
8438 active, because there is no way to handle the exception.
8439 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
8440 to do a minimum decoration of the Access_Disp_Table list.
8441 (Expand_Record_Controller): Avoid the addition of the controller between
8442 the component containing the tag of a secondary dispatch table and its
8443 adjacent component that stores the offset to the base of the object.
8444 This latter component is only generated when the parent type has
8445 discriminants ---documented in Add_Interface_Tag_Components).
8446 (Apply_Array_Size_Check): Removed, no longer needed.
8447 (Expand_N_Full_Type_Declaration): If the type has anonymous access
8448 components, create a Master_Entity for it only if it contains tasks.
8449 (Build_Init_Procedure): Suppress the tag assignment compiling under
8451 (Freeze_Record_Type): Remove code associated with creation of dispatch
8453 (Init_Secondary_Tags): Update type of actuals when generating calls to
8454 Ada.Tags.Set_Offset_To_Top
8455 (Stream_Operation_OK): Disable use of streams compiling under no
8457 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
8458 if Has_Init_Expression set.
8459 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
8460 Register_Primitive, which provides the same functionality.
8461 (Requires_Init_Proc): Return false in case of interface types.
8462 (Add_Secondary_Tables): Use the new attribute Related_Interface to
8464 (Predefined_Primitive_Freeze): Do not assume that an internal entity
8465 is always associated with a predefined primitive because the internal
8466 entities associated with interface types are not predefined primitives.
8467 Therefore, the call to Is_Internal is replaced by a call to the
8468 function Is_Predefined_Dispatching_Operation.
8469 (Make_Eq_If): When generating the list of comparisons for the
8470 components of a given variant, omit the controller component that is
8471 present if the variant has controlled components.
8473 2007-06-06 Javier Miranda <miranda@adacore.com>
8474 Hristian Kirtchev <kirtchev@adacore.com>
8475 Bob Duff <duff@adacore.com>
8477 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
8478 handle the creation of finalization lists and calls for nested
8479 coextensions when the root of the chains is part of a return statement.
8480 (Inside_A_Return_Statement): New function inside Complete_Coextension_
8482 (Expand_Record_Equality): Skip components that are interface types.
8483 (Displace_Allocator_Pointer): Add missing support for interface subtypes
8484 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
8485 with Rewrite_Coextension. Change the condition for detecting coextension
8487 (Is_Local_Access_Discriminant): Removed.
8488 (Rewrite_Coextension): New routine which rewrites a static coextension
8489 as a temporary and uses its unrestricted access in the construction of
8491 (Complete_Coextension_Finalization): New routine. Generate finalization
8492 attachment calls to all delayed coextensions.
8493 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
8494 the allocator is not a coextension itself and has delayed coextensions.
8495 If the current allocator is controlled, but also a coextension, delay
8496 the generation of the finalization attachment call.
8497 Rename local variable "Node" to "Nod" in order to avoid confusion with
8499 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
8500 limited types that are not inherently limited. Such an allocator is
8501 illegal, but is generated by the expander for a return statement, to
8502 copy the result onto the secondary stack. This is the only case where a
8503 limited object can be copied. Generate code to displace the pointer
8504 to the object if the qualified expression is a class-wide interface
8505 object. Such displacement was missing and hence the copy of the object
8507 (Apply_Accessibility_Check): Handle allocated objects initialized in
8509 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
8510 and Expand_Allocator_Expression. Allocating class-wide interface objects
8511 this routine displaces the pointer to the allocated object to reference
8512 the component referencing the corresponding secondary dispatch table.
8513 Expand_Allocator_Expression): Add missing support to allocate class-wide
8514 interface objects initialized with a qualified expression.
8515 (Get_Allocator_Final_List): Test for an anonymous access type that is a
8516 function result type, and use the finalization list associated with the
8517 function scope in that case (such an anonymous type should not be
8518 treated like an access parameter's type).
8520 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8521 Gary Dismukes <dismukes@adacore.com>
8522 Javier Miranda <miranda@adacore.com>
8524 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
8525 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
8526 required exception handler.
8527 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
8528 properly the case of a function whose return type is a limited
8529 class-wide interface type. Modify the code of the accessibility
8530 check to handle class-wide interface objects. In this case we need to
8531 displace "this" to reference the primary dispatch table to get access
8532 to the TSD of the object (to evaluate its accessibility level).
8533 (Expand_N_Extended_Return_Statement): Test for a tagged result type
8534 rather than a controlling result as one of the conditions for
8535 generating tests of the implicit BIP_Alloc_Form formal. The
8536 initialization assignment is also handled according to whether the
8537 result is tagged instead of controlling.
8538 In the case where the init assignment is inserted in the "then" part of
8539 the allocation conditional, rewrite the target to be a dereference of
8540 the implicit BIP_Object_Access formal.
8541 If the returned value is unconstrained and created on the secondary
8542 stack, mark the enclosing block and function so that the secondary
8543 stack is not reclaimed on return.
8544 Treat returns from functions with controlling results similarly to
8545 returns from functions with unconstrained result subtypes.
8546 If the object returned is unconstrained, and an allocator must be
8547 created for it, analyze the allocator once the block for the extended
8548 return is installed, to ensure that finalizable components
8549 of the expression use the proper finalization list. Guard the call to
8550 Move_Final_List with a check that there is something to finalize.
8551 (Make_Tag_Ctrl_Assignment): Use "old" handling
8552 of controlled type assignment for virtual machines, since new code uses
8553 unsupported features (such as direct access to bytes in memory).
8555 2007-06-06 Gary Dismukes <dismukes@adacore.com>
8556 Ed Schonberg <schonberg@adacore.com>
8558 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
8559 accessibility actual, check for the case of an aliased object that has
8560 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
8561 we fall into processing for the attribute rather than the name of the
8563 (Expand_Inline_Call): If an actual is a literal, and the corresponding
8564 formal has its address taken in the body, create a temporary to capture
8565 value. If the return type is a limited interface, do not treat the
8566 return value as Controlled.
8567 (Is_In_Place_Function): If the return type is a limited interface,
8568 treat as returning in place. The actual returned object may not always
8569 be limited, but the caller has to assume that it is returned in place.
8570 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
8571 context of an allocator, use the correct finalization chain (that is,
8572 the chain belonging to the access type, rather than the chain belonging
8573 to the current scope).
8574 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
8575 result type rather than a controlling result as a precondition for
8576 adding an allocation form actual to a build-in-place call.
8577 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
8578 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
8579 primitive in the dispatch tables. This work is now done by Make_DT when
8581 (Register_Predefined_DT_Entry): Removed.
8582 (Add_Return): If end label is not present, use sloc of last statement
8583 for generated return statement in procedure, for better gdb behavior
8585 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
8586 object address nodes to ensure proper processing by routines like
8588 (Expand_Call): Fix generation of validity check for parameter
8589 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
8590 the allocation form parameter if the result subtype is constrained,
8591 except when the function has a controlling result.
8592 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
8593 rather than Is_Controlled and Has_Controlled_Component, since we want to
8594 include class-wide result types in this treatment. Also test for a
8595 controlling result, since that also requires passing a finalization
8597 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
8598 even when the result subtype is constrained, to handle calls involving
8599 controlling results.
8600 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
8601 is now called even when the result subtype is constrained, to handle
8602 calls involving controlling results.
8603 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
8604 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
8605 now performs the test).
8606 (Make_Build_In_Place_Call_In_Object_Declaration):
8607 Add_Alloc_Form_Actual_* is now called even when the result subtype is
8608 constrained, to handle calls involving controlling results.
8609 (Add_Return): Accomodate rewritten pattern from local raise to goto
8610 transformation, so that we still recognize an transfer statement
8611 and do the right thing here in that case.
8612 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
8613 and end of subprogram code.
8614 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
8615 support for primitives that are functions (without formals) with a
8617 (Inherited_From_Formal): If the actual subtype has not generic parent
8618 type, it is not an actual for a formal derived type, and there is no
8619 operation to inherit from the formal.
8621 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8622 Thomas Quinot <quinot@adacore.com>
8624 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
8625 inserted cleanup code appropriately for GDB use.
8626 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
8627 exception handler for Deep_Adjust or Deep_Finalize.
8628 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
8629 Raise_From_Controlled_Operation is available, use a call to that
8630 subprogram instead of a plain "raise Program_Error" node to raise
8631 Program_Error if an exception is propagated from an Adjust or Finalize
8633 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
8634 appears in the optional statement list of a triggering alternative, the
8635 scope actions can be inserted directly there, and not in the list that
8636 includes the asynchronous select itself.
8638 2007-06-06 Ed Schonberg <schonberg@adacore.com>
8639 Robert Dewar <dewar@adacore.com>
8640 Hristian Kirtchev <kirtchev@adacore.com>
8642 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
8643 generated exception handler appropriately when debugging generated code.
8644 Deal properly with No_Exception_Propagation restriction mode.
8645 (Expand_N_Abort_Statement): Add an unchecked type conversion from
8646 System.Address to System.Tasking.Task_Id when processing the result of
8647 the predefined primitive _disp_get_task_id.
8648 (Expand_N_Asynchronous_Select): Clarify comment.
8649 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
8650 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
8651 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
8652 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
8653 privals and for generated call to Complete_Entry_Body, for better gdb
8655 (Copy_Result_Type): Utility to construct a parameter and result profile
8656 for protected functions whose return type is an anonymous access to
8658 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
8660 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
8661 point when the local-raise-to-goto transformation has taken place.
8663 2007-06-06 Javier Miranda <miranda@adacore.com>
8664 Nicolas Setton <setton@adacore.com>
8666 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
8667 functionality when the backend is generating code.
8668 Otherwise any serious error
8669 reported by the backend calling the frontend routine Error_Msg
8670 changes the Compilation_Mode to Check_Semantics, disables the

8812 subtype from the function call, as is done for private types.
8813 (Side_Effect_Free): An expression that is the renaming of an object or

10782 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
10783 when -gnatg is not specified.

10813 (Convert_Aggr_In_Allocator): If the allocator is for an access
10814 discriminant and the type is controlled. do not place on a finalization
10815 list at this point. The proper list will be determined from the

10835 parameter of the containing subprogram.
10836 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
10837 under No_Dispatching_Calls restriction. During the semantic analysis
10838 we already notified such violation.

10860 value that is used in the membership test but also to fix the size
10861 of the table of ancestors.
10862 (Expand_Interface_Conversion): Insert function body at the closest place

10980 for a possible overriding candidate.
10981 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
10982 hold an actual parameter value since its initialization is separated
10983 from the the declaration. Prevents errors on null-excluding access
10986 2007-04-06 Thomas Quinot <quinot@adacore.com>
10987 Pablo Oliveira <oliveira@adacore.com>
10989 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
10990 Do an Unchecked_Conversion to handle the passage from the Underlying
10991 Type to the Base Type when calling Build_To_Any_Call and
10992 Build_From_Any_Call.
10993 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
10994 E_Constant, depending upon Variable formal.
10995 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
10996 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
10997 parameter that requires an extra constrained parameter, declare
10998 temporary for actual as a variable, not a constant.
10999 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
11000 the unit being compiled is the one that contains the stub type.
11001 Change primitive operation name for the RACW associated with a RAS
11002 from Call to _Call so it cannot clash with any legal identifier.
11003 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
11005 (Append_RACW_Bodies): New subprogram.
11006 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
11007 Add_Receiving_Stubs_To_Declarations functions.
11008 When expanding a package body, this list correspond to the
11009 statements in the HSS at the end of the pacakge.
11010 When expanding a package spec, this list correspond to the
11012 (Add_Receiving_Stubs_To_Declarations): Append the function
11013 registering the receiving stubs at the end of the 'Stmts' list.
11014 (RCI_Package_Locator): Pass the new Version generic formal when
11015 instantiating a RCI_Locator package.
11016 (Build_From_Any_Function): To compute the High bound for an
11017 unconstrained array actual, we add the Low bound with the length.
11018 Thus we must convert the low bound and the length to an appropriate
11019 type before doing the sum.
11020 (Build_Subprogram_Receiving_Stubs, PolyORB):
11021 * Retrieve the extra formals parameters at the
11022 end of the parameter stream.
11023 * Use Move_Any_Value to write back out parameters
11024 after executing the request as it is more efficient
11025 than Copy_Any_Value.
11026 * Build the any containing Extra Formals with the
11027 appropriate typecode.
11028 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
11029 empty Component_List.
11030 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
11031 the tree the declaration for an object that serves as actual parameter
11032 in server-side stubs.
11033 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
11034 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
11035 Use Build_Actual_Object_Declaration to prepare the actuals.

11037 Extra Constrained Parameters.
11038 (Build_General_Calling_Stubs): Set the parameter type to boolean for
11039 Extra Constrained parameters.

11042 function with the first not implicit parent type.
11043 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
11044 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
11045 typecode from the Etype. Therefore we retrieve the correct typecode
11046 with a call to Get_Any_Type.
11047 (Copy_Specification): Do controlling formal type substitution based on
11048 Is_Controlling_Formal flag, instead of caller-provided object type.
11049 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
11050 a RACW primitive operation, we might get a subprogram declaration for an
11051 ancestor of the RACW designated type (not for the designated type
11052 itself), in the case where this operation is inherited. In this case we
11053 have no easy means of determining the original tagged type for which
11054 the primitive was declared, so instead we now rely on
11055 Copy_Specification to use the Is_Controlling_Formal flag to determine
11056 which formals require type substitution.

11062 GNAT.Current_Exception are not allowed if pragma Restrictions
11063 (No_Exception_Propagation) is set and in any case make the associated
11064 handler unsuitable as a target for a local raise statement.
11065 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
11066 run-time subprogram CW_Membership by call to Build_CW_Membership.
11067 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
11068 by a function call, a temporary must be created before expanding the
11069 Constructor_Call itself, to prevent out-of-order elaboration in the
11070 back-end when stack checking is enabled..
11072 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11074 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
11075 result are the bounds of the left operand, not the right.
11077 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11080 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use
11081 discriminant defaults.

11092 box corresponds to a component of the type.
11093 (Resolve_Record_Aggregate): Split Is_Abstract flag into
11094 Is_Abstract_Subprogram and Is_Abstract_Type.
11096 * exp_tss.adb (Base_Init_Proc): Use Is_Type instead of Type_Kind for
11099 * inline.adb (Add_Inlined_Body): Split Is_Abstract flag into
11100 Is_Abstract_Subprogram and Is_Abstract_Type. Make sure these are
11101 called only when appropriate.

11201 This is needed as it is necessary to have access to both versions in the
11202 runtime for the form parameter encoding support.
11203 This set of patch add support for the encoding form parameter.
11204 (S2WS): Improve implementation to handle cases where the filename is not
11205 UTF-8 encoded. In this case we default to using the current code page
11206 for the conversion.

11256 implementation of floating point operations as native x86 targets.
11257 So the FPU should be initialized in the same way using finit. Fix
11258 floating point operations accuracy issues.
11259 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
11260 member in struct sigaction, so as to avoid warning for incompatible

11449 * sem_ch13.ads, sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
11450 Use First/Next_Component_Or_Discriminant
11451 (Analyze_Record_Representation_Clause):

11453 (Check_Component_Overlap): Use First/Next_Component_Or_Discriminant
11454 (Analyze_Attribute_Definition_Clause, case Value_Size): Reject
11455 definition if type is unconstrained.
11456 (Adjust_Record_For_Reverse_Bit_Order): New procedure
11457 (Analyze_Attribute_Definition_Clause): Split Is_Abstract flag into
11458 Is_Abstract_Subprogram and Is_Abstract_Type.
11459 (Adjust_Record_For_Reverse_Bit_Order): New procedure
11461 * repinfo.adb (List_Record_Info): Use First/
11462 Next_Component_Or_Discriminant.
11464 * style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
11467 * stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch
11468 Include -gnatyA in default switches
11470 * opt.ads: (Warn_On_Non_Local_Exception): New flag
11471 (Warn_On_Reverse_Bit_Order): New flag
11472 (Extensions_Allowed): Update the documentation.
11473 (Warn_On_Questionable_Missing_Parens): Now on by default
11475 * usage.adb: Add documentation of -gnatw.x/X switches
11476 Document new -gnatyA style switch
11477 -gnatq warnings are on by default
11479 2007-04-06 Ed Falis <falis@adacore.com>
11481 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
11482 full word is no longer compared twice.
11484 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11486 * sem_ch10.adb (Install_Limited_Context_Clauses.
11487 Expand_Limited_With_Clause): Use a new copy of selector name in the
11488 call to Make_With_Clause. This fixes the tree structure for ASIS
11489 purposes. Nothing is changed in the compiler behaviour.
11490 (Process_Body_Clauses): Handle properly use clauses whose prefix is
11491 a package renaming.
11492 (Install_Limited_With_Clauses): Do not install non-limited view when it
11493 is still incomplete.
11495 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11496 Gary Dismukes <dismukes@adacore.com>
11498 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
11499 when capturing size information, instead of base type, which for a
11500 formal array type will be the unconstrained type.
11501 (Analyze_Formal_Object_Declaration): Add check for illegal default
11502 expressions for a formal in object of a limited type.
11503 (Instantiate_Object): Ditto.
11504 (Check_Formal_Package_Instance): Skip entities that are formal objects,
11505 because they were defaulted in the formal package and no check applies
11507 (Check_Formal_Package_Instance): Extend conformance check to other
11508 discrete types beyond Integer.
11509 (Process_Default): Copy directly the unmatched formal. A generic copy
11510 has already been performed in Analyze_Formal_Package.
11511 (Analyze_Associations): If a formal subprogram has no match, check for
11512 partial parametrization before looking for a default, to prevent
11514 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
11515 not set the instantiation environment before analyzing the actuals.
11516 Fixes regression on 8515-003 with implementation of AI-133.
11517 Set_Instance_Env checks whether the generic unit is a predefined
11518 unit, in which case the instance must be analyzed with the latest Ada
11519 mode. This setting must take place after analysis of the actuals,
11520 because the actuals must be analyzed and frozen in the Ada mode extant
11521 outside of the current instantiation.
11522 (Save_Env, Restore_Env): Preserve and restore the configuration
11523 parameters so that predefined units can be compiled in the proper Ada
11525 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
11526 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
11527 and Is_Abstract_Type.
11528 (Analyze_Formal_Package): For better error recovery, Add exception
11529 handler to catch Instantion_Error, which can be raised in
11530 Analyze_Associations
11532 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11533 Bob Duff <duff@adacore.com>
11534 Gary Dismukes <dismukes@adacore.com>
11536 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
11537 prefix type is a discriminated subtype of the type of the formal.
11538 (Analyze_Allocator): Collect all coextensions regardless of the context.
11539 Whether they can be allocated statically is determined in exp_ch4.
11540 (Analyze_Selected_Component): If the prefix is a limited view and the
11541 non-limited view is available, use the non-limited one.
11542 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
11543 therefore illegal), suggest a qualified expression rather than a type
11544 conversion, because a type conversion would be illegal in this context.
11545 (Anayze_Allocator): Trace recursively all nested allocators so that all
11546 coextensions are on the corresponding list for the root. Do no mark
11547 coextensions if the root allocator is within a declaration for a stack-
11548 allocated object, because the access discriminants will be allocated on
11550 (Analyze_Call): Remove restriction on calls to limited functions for the
11551 cases of generic actuals for formal objects, defaults for formal objects
11552 and defaults for record components.
11553 (Analyze_Allocator): Before analysis, chain coextensions on the proper
11554 element list. Their expansion is delayed until the enclosing allocator
11555 is processed and its finalization list constructed.
11556 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
11557 for an operation with the given name among the primitive operations of
11558 the corresponding record type.
11559 (Analyze_Selected_Component): If the prefix is a task type that
11560 implements an interface, and there is no entry with the given name,
11561 check whether there is another primitive operation (e.g. a function)
11563 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
11564 properly the indexing of a function call written in prefix form, where
11565 the function returns an array type, and all parameters of the function
11566 except the first have defaults.
11567 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
11568 the original operands, rather than relocating them, for efficiency and
11569 to work properly when an operand is overloaded.
11570 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
11571 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
11572 (Analyze_Selected_Component): If the prefix is a private extension, only
11573 scan the visible components, not those of the full view.
11574 (Try_Primitive_Operation): If the operation is a procedure, collect all
11575 possible interpretations, as for a function, because in the presence of
11576 classwide parameters several primitive operations of the type can match
11577 the given arguments.
11579 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11580 Robert Dewar <dewar@adacore.com>
11582 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
11583 tag-indeterminate call to an abstract function, when the left-hand side
11585 (Analyze_Loop_Statement): Improve detection of infinite loops
11587 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11588 Thomas Quinot <quinot@adacore.com>
11590 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
11591 out of Analyze_Package_Declaration, because processing must be applied
11592 to package bodies as well, for deferred constants completed by pragmas.
11593 (Analyze_Package_Declaration): When the package declaration being
11594 analyzed does not require an explicit body, call Check_Completion.
11595 (May_Need_Implicit_Body): An implicit body is required when a package
11596 spec contains the declaration of a remote access-to-classwide type.
11597 (Analyze_Package_Body): If the package contains RACWs, append the
11598 pending subprogram bodies generated by exp_dist at the end of the body.
11599 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
11600 Is_Abstract_Subprogram and Is_Abstract_Type.
11601 (Preserve_Full_Attributes): The full entity list is not an attribute
11602 that must be preserved from full to partial view.
11604 * sem_dist.adb (Add_RAS_Dereference_TSS):
11605 Change primitive name to _Call so it cannot clash with any legal
11606 identifier, and be special-cased in Check_Completion.
11607 Mark the full view of the designated type for the RACW associated with
11608 a RAS as Comes_From_Source to get proper view switching when installing
11609 private declarations.
11610 Provite a placeholder nested package body along with the nested spec
11611 to have a place for Append_RACW_Bodies to generate the calling stubs
11612 and stream attributes.
11614 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11615 Robert Dewar <dewar@adacore.com>
11617 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
11618 that is a limited view, check the non-limited view if available.
11619 (Undefined): Refine error message for missing with of Text_IO
11620 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
11621 to distinguish real missing with cases.
11622 Fix format of all missing with messages
11623 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
11624 renaming as body when renamed entity is abstract.
11626 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11627 Javier Miranda <miranda@adacore.com>
11629 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
11630 predicate recursive, to handle complex expressions on literals whose
11631 spurious ambiguity comes from the abstract interpretation of some
11633 (Interface_Present_In_Ancestor): Add support to concurrent record
11635 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
11636 Is_Abstract_Subprogram and Is_Abstract_Type.
11638 2007-04-06 Ed Schonberg <schonberg@adacore.com>
11639 Javier Miranda <miranda@adacore.com>
11641 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
11642 dereference of a local object R created as a reference to another
11643 object O, use the access level of O.
11644 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
11645 rather than local Same_Formal_Type, to check whether protected operation
11646 overrides an inherited one.
11647 (Same_Formal_Type): New predicate, used when matching signatures of
11648 overriding synchronized operations, to handle the case when a formal
11649 has a type that is a generic actual.
11650 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
11651 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
11652 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
11653 syntactic ambiguities involving indexing of function calls that return
11655 (Abstract_Interface_List): New subprogram that returns the list of
11656 abstract interfaces associated with a concurrent type or a
11657 concurrent record type.
11658 (Interface_Present_In_Parent): New subprogram used to check if a
11659 given type or some of its parents implement a given interface.
11660 (Collect_Abstract_Interfaces): Add support for concurrent types
11661 with interface types.
11662 (Has_Abstract_Interfaces): Add support for concurrent types with
11664 (Is_Parent): New subprogram that determines whether E1 is a parent
11665 of E2. For a concurrent type its parent is the first element of its
11666 list of interface types; for other types this function provides the
11667 same result than Is_Ancestor.
11668 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
11669 (Collect_Synchronized_Interfaces): Removed because the subprogram
11670 Collect_Abstract_Interfaces provides this functionality.
11671 (Collect_Abstract_Interfaces): Minor update to give support to
11672 concurrent types and thus avoid undesired code duplication.
11673 (Get_Subprogram_Entity): Handle entry calls.
11674 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
11676 (Enter_Name): Do not give -gnatwh hiding warning for record component
11677 entities, they never result in hiding.

11686 New field Exception_Label added
11687 (Local_Raise_Statements): New field in N_Exception_Handler_Node
11688 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

11690 correspond to access discriminants of dynamically allocated objects.
11691 (N_Block_Statement): Document the fact that the corresponding entity
11692 can be an E_Return_Statement.
11693 (Is_Coextension): New flag for allocators.
11694 Remove all code for DSP option

11712 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
11713 expression with a COMPOUND_EXPR including the call instead of emitting
11714 the call directly here.
11715 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
11716 high bound is constant and the slice is empty. Tidy.
11717 (tree_transform, case N_Op_Not): Handle properly the case where the
11718 operation applies to a private type whose full view is a modular type.
11719 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
11720 Address_Clause, use the associated Expression as the GNAT tree
11721 representing the choice value to ensure the corresponding GCC tree is
11722 of the proper kind.
11723 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
11724 instead of just the operands, as the base GCC stabilize_reference does.
11725 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
11726 requested; otherwise fail.
11727 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

11732 implementation of UI_Div.
11733 (UI_Div): Reimplement as a call to UI_Div_Rem.
11734 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
11735 remainder, avoiding the cost of a multiplication and a subtraction.
11736 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
11737 provides both quotient and remainder in a single computation.
11738 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
11739 functions for uint.
11740 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram

11987 (mainly static expression evaluation).
11988 Reword some continuation messages
11989 Add some \\ sequences to continuation messages
11990 (Resolve_Call): Refine infinite recursion case. The test has been

12006 Valid_Conversion, to incorporate accessibility checks for arrays of
12007 anonymous access types.
12008 (Valid_Conversion): For a conversion to a numeric type occurring in an
12009 instance or inlined body, no need to check that the operand type is
12010 numeric, since this has been checked during analysis of the template.

12598 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
12599 assignments where the target subtype is unconstrained and the target
12600 object is a parameter or dereference (other aliased cases are known

12767 an aliased prefix must be known to be constrained in order to use True
12768 for the attribute value, and now it's possible for some aliased views

12780 Gary Dismukes <dismukes@adacore.com>
12782 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
12783 register in the final list objects containing class-wide interfaces;
12784 otherwise we incorrectly register the tag of the interface in the final
12786 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
12787 generate the wrapper if the parent primitive is abstract. This is
12788 required to report the correct error message.
12789 (Expand_N_Subtype_Indication): Do validity checks on range
12790 (Clean_Task_Names): If an initialization procedure includes a call to
12791 initialize a task (sub)component, indicate that the procedure will use
12792 the secondary stack.
12793 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
12794 compatibility for interfacing with CPP by default.
12795 (Expand_N_Object_Declaration): Only build an Adjust call when the
12796 object's type is a nonlimited controlled type.
12797 * exp_ch3.adb: Add with and use of Exp_Ch6.
12798 (Expand_N_Object_Declaration): Check for object initialization that is a
12799 call to build-in-place function and apply Make_Build_In_Place_Call_In_
12800 Object_Declaration to the call.
12801 (Freeze_Type): When the designated type of an RACW was not frozen at the
12802 point where the RACW was declared, validate the primitive operations
12803 with respect to E.2.2(14) when it finally is frozen.
12804 (Build_Initialization_Call,Expand_Record_Controller): Rename
12805 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
12806 return-by-reference has no meaning in Ada 2005.
12807 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
12808 to register tag of the immediate ancestor interfaces in the
12809 run-time structure.
12810 (Init_Secondary_Tags): Moved to the specification to allow the
12811 initialization of extension aggregates with abstract interfaces.
12812 (Build_Master_Renaming): Make public, for use by function declarations
12813 whose return type is an anonymous access type.
12814 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
12815 Insert_List_Before_And_Analyze after the generation of the specs
12816 associated with null procedures.
12817 (Expand_Tagged_Root): Update documentation in its specification.
12818 (Init_Secondary_Tags): Update documentation.
12819 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
12820 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
12821 then generate code to inherit the contents of the dispatch table
12822 directly from the ancestor.
12823 (Expand_Record_Controller): Insert controller component after tags of
12824 implemented interfaces.
12825 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
12826 create null procedure overridings when null procedures are inherited
12828 (Make_Null_Procedure_Specs): New procedure to generate null procedure
12829 declarations for overriding null primitives inherited from interfaces.
12830 (Is_Null_Interface_Procedure): New function in
12831 Make_Null_Procedure_Specs.
12832 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
12833 immediate ancestor of a tagged type is an abstract interface type we
12834 must generate the specification of the predefined primitives associated
12835 with controlled types (because the dispatch table of the ancestor is
12836 null and hence these entries cannot be inherited). This is required to
12837 elaborate well the dispatch table.

12842 Gary Dismukes <dismukes@adacore.com>
12843 Robert Dewar <dewar@adacore.com>
12845 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
12847 (Expand_N_In): Do validity checks on range
12848 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
12849 (Expand_N_Allocator): For "new T", if the object is constrained by
12850 discriminant defaults, allocate the right amount of memory, rather than
12851 the maximum for type T.
12852 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
12853 when the allocator is initialized by a build-in-place call, since the
12854 allocator is already rewritten as a reference to the function result,
12855 and this prevents an unwanted duplication of the function call.
12856 Add with and use of Exp_Ch6.
12857 (Expand_Allocator_Expresssion): Check for an allocator whose expression
12858 is a call to build-in-place function and apply
12859 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
12860 untagged designated types).
12861 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
12862 optimization if source or target is biased.
12863 (Expand_N_Allocator): Add comments for case of an allocator within a
12864 function that returns an anonymous access type designating tasks.
12865 (Expand_N_Allocator): apply discriminant checks for access
12866 discriminants of anonymous access types (AI-402, AI-416)

12871 Ed Schonberg <schonberg@adacore.com>
12873 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
12875 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
12876 (Expand_N_Assignment_Statement): Call
12877 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
12878 build-in-place function call. Currently, this can happen only for
12879 assignments that come from aggregates.
12880 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
12881 in order to alleviate the upward compatibility introduced by AI-318.
12882 (Expand_N_Extended_Return_Statement): Add support for handling the
12883 return object as a build-in-place result.
12884 (Expand_Non_Function_Return): Implement simple return statements nested
12885 within an extended return.
12886 (Enable_New_Return_Processing): Turn on the new processing of return
12888 (Expand_Non_Function_Return): For a return within an extended return,
12889 don't raise Program_Error, because Sem_Ch6 now gives a warning.
12890 (Expand_N_Extended_Return_Statement): Implement AI-318
12891 (Expand_Simple_Function_Return): Ditto.
12892 (Expand_N_If_Statement): Handle new -gnatwt warning
12893 (Expand_N_Case_Statement): Handle new -gnatwt warning
12894 (Expand_N_Assignment): Handle assignment to the Priority attribute of
12895 a protected object.
12896 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
12897 validity checking of assignments to elementary record components.
12898 (Expand_N_Return_Statement): return Class Wide types on the secondary
12899 stack independantly of their controlled status since with HIE runtimes,
12900 class wide types are not potentially controlled anymore.
12902 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
12905 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
12906 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
12907 it expects a block, procedure, or task. The return statement will get
12908 turned into a block, and Expand_Cleanup_Actions will happen then.
12910 2006-10-31 Robert Dewar <dewar@adacore.com>
12911 Ed Schonberg <schonberg@adacore.com>
12912 Bob Duff <duff@adacore.com>
12913 Gary Dismukes <dismukes@adacore.com>
12915 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
12917 (Expand_Inlined_Call): Tagged types are by-reference types, and
12918 therefore should be replaced by a renaming declaration in the expanded
12919 body, as is done for limited types.
12920 (Expand_Call): If this is a call to a function with dispatching access
12921 result, propagate tag from context.
12922 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
12924 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
12925 build-in-place when the right-hand side of an assignment is a
12926 build-in-place function call.
12927 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
12928 of the explicit dereference of the allocator to the result subtype of
12929 the build-in-place function. This is needed to satisfy type checking
12930 in cases where the caller's return object is created by an allocator for
12931 a class-wide access type and the type named in the allocator is a
12933 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
12934 conversion of the reference to the declared object to the result subtype
12935 of the build-in-place function. This is needed to satisfy type checking
12936 in cases where the declared object has a class-wide type. Also, in the
12937 class-wide case, change the type of the object entity to the specific
12938 result subtype of the function, to avoid passing a class-wide object
12939 without explicit initialization to the back end.
12940 (Register_Interface_DT_Entry): Moved outside the body of
12941 Freeze_Subprogram because this routine is now public; it is called from
12942 Check_Dispatching_Overriding to handle late overriding of abstract
12943 interface primitives.
12944 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
12945 adding an implicit access actual on a call to a build-in-place function.
12946 (Expand_Actuals): Test for an actual parameter that is a call to a
12947 build-in-place function and apply
12948 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
12949 (Is_Build_In_Place_Function): New function to determine whether an
12950 entity is a function whose calls should be handled as build-in-place.
12951 (Is_Build_In_Place_Function_Call): New function to determine whether an
12952 expression is a function call that should handled as build-in-place.
12953 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
12954 calls to build-in-place functions as the initialization of an allocator.
12955 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
12956 handling calls to build-in-place functions in contexts that do not
12957 involve init of a separate object (for example, actuals of subprogram
12959 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
12960 handling calls to build-in-place functions as the initialization of an
12961 object declaration.
12962 (Detect_Infinite_Recursion): Add explicit parameter Process to
12963 instantiation of Traverse_Body to avoid unreferenced warning.
12964 (Check_Overriding_Inherited_Interfaces): Removed.
12965 (Register_Interface_DT_Entry): Code cleanup.
12966 (Register_Predefined_DT_Entry): Code cleanup.
12967 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
12968 inlined statements if within a transient scope.
12969 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
12970 formal parameters with occurrences of actuals in inlined body, establish
12971 visibility on the proper view of the actual's subtype for the body's
12973 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
12974 compatibility mode and we have an imported CPP subprogram because
12975 for now we assume that imported CPP primitives correspond with
12976 objects whose constructor is in the CPP side (and therefore we
12977 don't need to generate code to register them in the dispatch table).
12978 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
12979 aligned selected component.
12980 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
12981 the actual of an in-mode parameter is a type conversion.
12982 (Expand_Actuals): If the call does not come from source and the actual
12983 is potentially misaligned, let gigi handle it rather than rejecting the
12984 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
12985 Class Wide types as returning by reference independantly of their
12986 controlled status since with HIE runtimes class wide types are not
12987 potentially controlled anymore.
12989 2006-10-31 Ed Schonberg <schonberg@adacore.com>
12991 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
12992 references that are private components of the protected object.
12993 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
12994 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
12995 instantiation to deal with warnings.
12996 (Initialize_Protection): If expression for priority is non-static, use
12997 System_Priority as its expected type, in case the expression has not
13000 2006-10-31 Robert Dewar <dewar@adacore.com>
13002 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
13003 initialization of Homonym_Len.
13004 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
13005 names from fully qualified name. Fixes problem of duplicate
13006 external names differing only in the presence of such a block name.
13008 2006-10-31 Thomas Quinot <quinot@adacore.com>
13009 Pablo Oliveira <oliveira@adacore.com>
13011 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
13012 subprogram Ids, even if they are not yet assigned.
13013 (Build_Subprogram_Id): It is now this function that will take care of
13014 calling Assign_Subprogram_Ids if necessary.
13015 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
13016 should be done only once they are assigned.
13017 (Build_From_Any_Function, case of tagged types): Add missing call to
13019 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
13020 type for an RACW type.
13021 (Add_RACW_Features): When processing an RACW declaration for which the
13022 designated type is already frozen, enforce E.2.2(14) rules immediately.
13023 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
13024 special reordering of controlling formals.
13026 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
13027 associated stub type for an RACW type.
13029 2006-10-31 Ed Schonberg <schonberg@adacore.com>
13031 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
13032 fixed-point operations in an integer context, i.e. as operands of a
13033 conversion to an integer type, indicate that result must be rounded.
13035 2006-10-31 Robert Dewar <dewar@adacore.com>
13037 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
13038 cases, pass the encoding method, since it is now required by the run
13041 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
13042 assumption that Str'First = 1.
13043 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
13044 it on to the Value_Wide_Wide_Character call.
13045 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
13046 properly handles a string of the form quote-encoded_wide_char-quote.
13048 * s-wchcnv.adb: Minor reformatting
13050 2006-10-31 Javier Miranda <miranda@adacore.com>
13052 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
13053 run-time membership test to ensure that the constructed object
13054 implements the target abstract interface.
13056 2006-10-31 Robert Dewar <dewar@adacore.com>
13058 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
13059 Machine_Attribute pragma internally to implement the user pragma.
13060 Add processing for pragma Interface so that it is now completely
13061 equivalent to pragma Import.
13063 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
13064 so that it can be applied to all entities, including record components
13065 and enumeration literals.
13066 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
13067 priority ranges are correct, verify compatibility against task
13068 dispatching and locking policies, and if everything is correct an entry
13069 is added to the table containing priority specific dispatching entries
13070 for this compilation unit.
13071 (Delay_Config_Pragma_Analyze): Delay processing
13072 Priority_Specific_Dispatching pragmas because when processing the
13073 pragma we need to access run-time data, such as the range of
13074 System.Any_Priority.
13075 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
13076 Allow pragma Unreferenced as a context item
13077 Add pragma Preelaborable_Initialization
13078 (Analyze_Pragma, case Interface): Interface is extended so that it is
13079 now syntactically and semantically equivalent to Import.
13080 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
13081 insertion characters.
13082 Add handling for Pragma_Wide_Character_Encoding
13083 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
13084 never supercedes a real restriction, and that a real restriction
13085 always supercedes a warning.
13086 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

13091 Robert Dewar <dewar@adacore.com>
13093 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
13094 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
13095 Is_Inherently_Limited_Type, because return-by-reference has no meaning
13097 (Find_Node_To_Be_Wrapped): Use new method of determining the result
13098 type of the function containing a return statement, because the
13099 Return_Type field was removed. We now use the Return_Applies_To field.
13101 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
13102 (Build_Task_Image_Decl): If procedure is not called from an
13103 initialization procedure, indicate that function that builds task name
13104 uses the sec. stack. Otherwise the enclosing initialization procedure
13105 will carry the indication.
13106 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
13107 N_Object_Declaration instead.
13108 (Kill_Dead_Code): New interface to implement -gnatwt warning for
13109 conditional dead code killed, and change implementation accordingly.
13110 (Insert_Actions): Add N_Return_Object_Declaration case.
13111 Correct comment to mention N_Extension_Aggregate node.
13112 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
13113 attempts to save information for global variables which cannot be
13115 (Get_Current_Value_Condition): Handle conditions the other way round
13116 (constant on left). Also handle right operand of AND and AND THEN
13117 (Set_Current_Value_Condition): Corresponding changes
13118 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
13119 (Get_Current_Value_Condition): Handle simple boolean operands
13120 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
13121 (Get_Current_Value_Condition): If the variable reference is within an
13122 if-statement, does not appear in the list of then_statments, and does
13123 not come from source, treat it as being at unknown location.
13124 (Get_Current_Value_Condition): Enhance to allow while statements to be
13125 processed as well as if statements.
13126 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
13128 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
13129 of loop. This is safe now that we fixed Kill_Current_Values.
13130 (OK_To_Do_Constant_Replacement): Check whether current scope is
13131 Standard, before examining outer scopes.
13133 2006-10-31 Vincent Celier <celier@adacore.com>
13135 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
13136 When True, apply VMS treatment to children of packages A, G, I and S.
13139 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
13141 2006-10-31 Robert Dewar <dewar@adacore.com>
13142 Ed Schonberg <schonberg@adacore.com>
13144 * freeze.adb: Add handling of Last_Assignment field
13145 (Warn_Overlay): Supply missing continuation marks in error msgs
13146 (Freeze_Entity): Add check for Preelaborable_Initialization
13148 * g-comlin.adb: Add Warnings (Off) to prevent new warning
13150 * g-expect.adb: Add Warnings (Off) to prevent new warning
13152 * lib-xref.adb: Add handling of Last_Assignment field
13153 (Generate_Reference): Centralize handling of pragma Obsolescent here
13154 (Generate_Reference): Accept an implicit reference generated for a
13155 default in an instance.
13156 (Generate_Reference): Accept a reference for a node that is not in the
13157 main unit, if it is the generic body corresponding to an subprogram
13160 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
13162 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
13164 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
13166 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
13167 use clauses, to avoid messages on packages used to qualify, and also
13168 to avoid messages from obsolescent units.
13169 (Warn_On_Useless_Assignments): Don't generate messages for imported
13170 and exported variables.
13171 (Warn_On_Useless_Assignments): New procedure
13172 (Output_Obsolescent_Entity_Warnings): New procedure
13173 (Check_Code_Statement): New procedure
13175 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
13176 Change name Is_Ada_2005 to Is_Ada_2005_Only
13177 (Last_Assignment): New field for useless assignment warning
13179 2006-10-31 Olivier Hainque <hainque@adacore.com>
13181 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
13182 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
13184 2006-10-31 Bob Duff <duff@adacore.com>
13185 Robert Dewar <dewar@adacore.com>
13186 Ed Schonberg <schonberg@adacore.com>
13188 * g-awk.adb (Default_Session, Current_Session): Compile this file in
13189 Ada 95 mode, because it violates the new rules for AI-318.
13191 * g-awk.ads: Use overloaded subprograms in every case where we used to
13192 have a default of Current_Session. This makes the code closer to be
13193 correct for both Ada 95 and 2005.
13195 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
13196 code, relying on the fact that the compiler generates a warning
13197 instead of an error in -gnatg mode.
13199 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
13200 E_Return_Statement entity kind.
13201 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
13203 * par.adb (P_Interface_Type_Definition): Addition of one formal to
13204 report an error if the reserved word abstract has been previously found.
13205 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
13207 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
13208 parenthesized range attribute usage
13209 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
13211 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
13212 in the syntax for extended_return_statement. This is not in the latest
13213 RM, but the ARG is expected to issue an AI allowing this.
13214 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
13215 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
13216 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
13217 P_Return_Statement): Parse the new syntax for extended_return_statement.
13219 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
13220 Output_End_Missing): Add error-recovery code for the new
13221 extended_return_statement syntax; that is, the new E_Return entry on
13224 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
13225 limited to nonlimited, because otherwise we violate the new Ada 2005
13226 rules about returning limited types in function Create_AST_Handler in
13229 * sem.adb (Analyze): Add cases for new node kinds
13230 N_Extended_Return_Statement and N_Return_Object_Declaration.
13232 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
13233 type is in the same category as type of context before applying check,
13234 to prevent anomalies in instantiations.
13235 (Resolve_Aggregate): Remove test for limited components in aggregates.
13236 It's unnecessary in Ada 95, because if it has limited components, then
13237 it must be limited. It's wrong in Ada 2005, because limited aggregates
13239 (Resolve_Record_Aggregate): Move check for limited types later, because
13240 OK_For_Limited_Init requires its argument to have been resolved.
13241 (Get_Value): When copying the component default expression for a
13242 defaulted association in an aggregate, use the sloc of the aggregate
13243 and not that of the original expression, to prevent spurious
13244 elaboration errors, when the expression includes function calls.
13245 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
13246 were missing. We also didn't handle qualified expressions. Now also
13247 allow function calls. Use new common routine OK_For_Limited_Init.
13248 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
13249 with space can upper case letter).
13251 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
13252 Has_Static_Discriminants flag
13253 (Record_Type_Declaration): Diagnose an attempt to declare an interface
13254 type with discriminants.

13256 (Build_Discriminant_Constraints): Use updated form of
13257 Denotes_Discriminant.
13258 (Process_Subtype): If the subtype is a private subtype whose full view
13259 is a concurrent subtype, introduce an itype reference to prevent scope
13261 (Build_Derived_Record_Type, Collect_Interface_Primitives,
13262 Record_Type_Declaration): The functionality of the subprograms
13263 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
13264 is now performed by a single routine.
13265 (Build_Derived_Record_Type): If the type definition includes an explicit
13266 indication of limitedness, then the type must be marked as limited here
13267 to ensure that any access discriminants will not be treated as having
13268 a local anonymous access type.
13269 (Check_Abstract_Overriding): Issue a detailed error message when an
13270 abstract subprogram was not overridden due to incorrect mode of its
13272 (Analyze_Private_Extension_Declaration): Add support for the analysis of
13273 synchronized private extension declarations. Verify that the ancestor is
13274 a limited or synchronized interface or in the generic case, the ancestor
13275 is a tagged limited type or synchronized interface and all progenitors
13276 are either limited or synchronized interfaces.
13277 Derived_Type_Declaration): Check for presence of private extension when
13278 dealing with synchronized formal derived types.
13279 Process_Full_View): Enchance the check done on the usage of "limited" by
13280 testing whether the private view is synchronized.
13281 Verify that a synchronized private view is completed by a protected or
13283 (OK_For_Limited_Init_In_05): New function.
13284 (Analyze_Object_Declaration): Move check for limited types later,
13285 because OK_For_Limited_Init requires its argument to have been resolved.
13286 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
13287 in order to alleviate the upward compatibility introduced by AI-318.
13288 (Constrain_Corresponding_Record): If the constraint is for a component
13289 subtype, mark the itype as frozen, to avoid out-of-scope references to
13290 discriminants in the back-end.
13291 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
13292 this subprogram against wrong sources.
13293 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
13294 discriminant of limited type completed with a protected type, when the
13295 discriminant is used to constrain a private component of the type, and
13296 expansion is disabled.
13297 (Find_Type_Of_Object): Do not treat a return subtype that is an
13298 anonymous subtype as a local_anonymous_type, because its accessibility
13299 level is the return type of the enclosing function.
13300 (Check_Initialization): In -gnatg mode, turn the error "cannot
13301 initialize entities of limited type" into a warning.
13302 (OK_For_Limited_Init): Return true for generated nodes, since it
13303 sometimes violates the legality rules.
13304 (Make_Incomplete_Declaration): If the type for which an incomplete
13305 declaration is created happens to be the currently visible entity,
13306 preserve the homonym chain when removing it from visibility.
13307 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
13308 inherited subprograms.
13309 (Access_Definition): If this is an access to function that is the return
13310 type of an access_to_function definition, context is a type declaration
13311 and the scope of the anonymous type is the current one.
13312 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
13313 incomplete subtype to the set of private dependents of the original
13315 (Constrain_Discriminated_Type): Emit an error message whenever an
13316 incomplete subtype is being constrained.
13317 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
13318 corresponding subtype of the full view of the original incomplete type.
13319 (Check_Incomplete): Properly detect invalid usage of incomplete types

13333 Robert Dewar <dewar@adacore.com>
13335 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
13336 handling executable extension manually and duplicating code.
13338 * make.adb: Implement new -S switch
13339 (Gnatmake): Use new function Osint.Executable_Name instead
13340 of handling executable extension manually.
13342 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
13343 is specified, the executable name ends with this suffix.
13344 Take advantage of Osint.Executable_Name instead of duplicating code.
13346 * switch-m.adb: Recognize new gnatmake -S switch
13348 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
13350 (Get_Target_Parameters): Set Executable_Extension_On_Target if
13353 * makeusg.adb: Add line for gnatmake -S switch
13355 2006-10-31 Vincent Celier <celier@adacore.com>
13357 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
13358 call it with -static-libgcc, as there are some platforms, such as
13359 Darwin, where one of these two switches is compulsory to link.
13361 2006-10-31 Vincent Celier <celier@adacore.com>
13363 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
13364 instead of ADA_PROJECT_PATH, for the project path.
13365 (Gnatls): When displaying the project path directories, use host dir
13368 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
13369 names in the project path, as absolute paths may correspond to
13370 multi-valued VMS logical names.
13372 2006-10-31 Vincent Celier <celier@adacore.com>
13374 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an

13376 (Locate_Regular_File): Ditto
13377 (Change_Dir): Remove, no longer used
13378 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
13379 on Windows. Get it calling Get_Current_Dir.

13381 (Normalize_Pathname)[VMS]: Do not resolve directory names.
13382 (Pid_To_Integer): New function to convert a Process_Id to Integer
13384 2006-10-31 Thomas Quinot <quinot@adacore.com>

13387 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
13389 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
13392 2006-10-31 Robert Dewar <dewar@adacore.com>

13401 2006-10-31 Robert Dewar <dewar@adacore.com>
13403 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
13405 (Layout_Variant_Record): Retrieve the discriminants from the entity
13406 rather than from the type definition, because in the case of a full
13407 type for a private type we need to take the discriminants from the
13409 (Layout_Component_List): When applying the Max operator to variants with
13410 a nonstatic size, check whether either operand is static and scale that
13411 operand from bits to storage units before applying Max.
13412 (Layout_Type): In VMS, if a C-convention access type has no explicit
13413 size clause (and does not inherit one in the case of a derived type),
13414 then the size is reset to 32 from 64.
13416 2006-10-31 Vincent Celier <celier@adacore.com>
13418 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
13419 its file has already been loaded, according to the unit being loaded,
13420 not to the current value of Multiple_Unit_Index.
13422 2006-10-31 Thomas Quinot <quinot@adacore.com>
13423 Eric Botcazou <ebotcazou@adacore.com>

13455 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
13458 2006-10-31 Ed Schonberg <schonberg@adacore.com>
13460 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
13461 Process_Body_Clauses): If the context of a body includes a use clause
13462 for P.Q then a with_clause for P in the same body is not redundant,
13463 even if the spec also has a with_clause on P.
13464 Add missing continuation mark to error msg
13465 (Build_Limited_Views): A limited view of a type is tagged if its
13466 declaration includes a record extension.
13467 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
13468 node, even if the subunit has errors. This avoids malfunction by
13469 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
13470 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
13471 generation of obsolescent messages for with statements (cannot do
13472 this too early, or we cannot implement avoiding the messages in the
13473 case of obsolescent units withing obsolescent units).
13474 (Install_Siblings): If the with_clause is on a remote descendant of
13475 an ancestor of the current compilation unit, find whether there is
13476 a sibling child unit that is immediately visible.
13477 (Remove_Private_With_Clauses): New procedure, invoked after completing
13478 the analysis of the private part of a nested package, to remove from
13479 visibility the private with_clauses of the enclosing package
13481 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
13482 now centralized in Generate_Reference.
13483 (Install_Limited_Context_Clauses): Remove superfluous error
13484 message associated with unlimited view visible through use
13485 and renamings. In addition, at the point in which the error
13486 is reported, we add the backslash to the text of the error
13487 to ensure that it is reported as a single error message.
13488 Use new // insertion for some continuation messages
13489 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
13490 to create implicit with_clause for parent unit mentioned in original
13491 limited_with_clause.
13492 (Install_Limited_With_Unit): Set entity of parent identifiers if the
13493 unit is a child unit. For ASIS queries.
13494 (Analyze_Subunit): If the subunit appears within a child unit, make all
13495 ancestor child units directly visible again.

13510 a formal object declaration with an access definition or a subtype mark
13511 with a null exclusion.
13512 (P_Generic_Association): Handle association with box, and others_choice
13513 with box, to support Ada 2005 partially parametrized formal packages.
13515 2006-10-31 Robert Dewar <dewar@adacore.com>
13516 Javier Miranda <miranda@adacore.com>
13518 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
13519 (P_Type_Declaration): Remove barrier against the reserved word "limited"

13521 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
13522 private extensions.
13523 (P_Type_Declaration): Add the new actual Abstract_Present to every call

13526 if the reserved word abstract has been previously found.
13527 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
13528 object renaming declaration with an access definition or subtype mark
13529 with a possible null exclusion.

13553 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
13554 on VMS, change "__" to '.' before checking the name.
13555 (Record_Ada_Source): Always add the source file name in the list of
13556 of sources, even if it is not the first time, as it is for another
13558 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
13559 dot, instead of replacing only the first '_'.
13561 * prj-part.adb (Parse): Convert project file path to canonical form
13563 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
13564 extended, the project id of the project extending it is recorded in its
13565 data, even when it has already been processed as an imported project.
13567 2006-10-31 Robert Dewar <dewar@adacore.com>
13569 * repinfo.adb (List_Entities): Don't list entities from renaming

13573 Robert Dewar <dewar@adacore.com>
13575 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
13576 only a restriction warning is active for the given restriction. This is
13577 desirable because we do not want to modify code in the case where only
13579 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
13580 causes overriding of real restrictions.
13581 Take advantage of new No_Restrictions constant.
13583 * raise.h: (__gnat_set_globals): Change profile.
13585 2006-10-31 Arnaud Charlet <charlet@adacore.com>

13613 attribute whose prefix is the type of an enclosing aggregate.
13614 Generalizes previous mechanism to handle attribute references nested
13615 arbitrarily deep within the aggregate.
13616 (Analyze_Access_Attribute): An access attribute whose prefix is a type
13617 can appear in an aggregate if this is a default-initialized aggregate
13618 for a self-referential type.
13619 (Resolve_Attribute, case Access): Ditto.
13620 Add support for new implementation defined attribute Stub_Type.
13621 (Eval_Attribute, case Attribute_Stub_Type): New case.
13622 (Analyze_Attribute, case Attribute_Stub_Type): New case.
13623 (Stream_Attribute_Available): Implement using new subprogram from

13626 Disallow Storage_Size and Storage_Pool for access to subprogram
13627 (Resolve_Attribute, case 'Access et al): Take into account anonymous
13628 access types of return subtypes in extended return statements. Remove

13632 a class-wide interface to a tagged type.
13633 Add support for the attribute Priority.
13634 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
13635 whether the designated type is discriminated with a constrained partial
13636 view and require static matching in that case.
13637 Add local variable Des_Btyp. The Designated_Type
13638 of an access to incomplete subtype is either its non-limited view if
13639 coming from a limited with or its etype if regular incomplete subtype.
13641 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
13642 Fix predicate to identify and allow cases of (expander-generated)
13643 references to tag of designated object of a RACW.
13644 (Validate_Static_Object_Name): In Ada 2005, a formal object is
13645 non-static, and therefore cannot appear as a primary in a preelaborable

13648 Has_Read_Write_Attributes.
13649 (Has_Read_Write_Attributes): Reimplement in termes of

13655 2006-10-31 Robert Dewar <dewar@adacore.com>
13657 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
13658 useless assignments here and conditionalize it on absence of exception
13660 (Analyze_Exception_Handlers): Small code reorganization of error
13661 detection code, for new handling of formal packages.

13674 synchronized formal derived type is a synchronized tagged type.
13675 (Instantiate_Formal_Package): When creating the instantiation used to
13676 validate the actual package of a formal declared without a box, check
13677 whether the formal itself depends on a prior actual.
13678 (Instantiate_Formal_Subprogram): Create new entities for the defining
13679 identifiers of the formals in the renaming declaration, for ASIS use.
13680 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
13681 a renaming declaration or a subtype declaration for an actual in an
13682 instance, capture location information of declaration in generic, for
13684 (Instantiate_Formal_Package): Add comments on needed additional tests.
13685 AI-317 (partial parametrization) is fully implemented.
13686 (Validate_Private_Type_Instance): Add check for actual which
13687 must have preelaborable initialization
13688 Use new // insertion for some continuation messages
13689 (Analyze_Formal_Object_Declaration): Change usage of Expression to
13690 Default_Expression. Add type retrieval when the declaration has an
13691 access definition. Update premature usage of incomplete type check.
13692 (Check_Access_Definition): New subsidiary routine. Check whether the
13693 current compilation version is Ada 05 and the supplied node has an
13695 (Instantiate object): Alphabetize local variables. Handle the creation
13696 of new renaming declarations with respect to the kind of definition
13697 used - either an access definition or a subtype mark. Guard against
13698 unnecessary error message in the context of anonymous access types after
13699 they have been resolved. Add check for required null exclusion in a
13700 formal object declaration.
13701 (Switch_View): A private subtype of a non-private type needs to be
13702 switched (the base type can have been switched without its private
13703 dependents because of the last branch of Check_Private_View.
13704 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
13706 (Instantiate_Type): Emit an error message whenever a class-wide type of
13707 a tagged incomplete type is used as a generic actual.
13708 (Find_Actual_Type): Extend routine to handle a component type in a child
13709 unit that is imported from a formal package in a parent.
13710 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
13711 agree on constrainedness, rather than checking against ultimate ancestor
13712 (Instantiate_Subprogram_Body): Create a cross-reference link to the
13713 generic body, for navigation purposes.

13716 Thomas Quinot <quinot@adacore.com>
13718 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
13720 (New_Stream_Subprogram): When processing an attribute definition clause
13721 for a stream-oriented subprogram, record an entity node occurring at
13722 the point of clause to use for checking the visibility of the clause,
13723 as defined by 8.3(23) as amended by AI-195.
13724 (New_Stream_Subprogram): New procedure, factoring behaviour from both
13725 New_Stream_Function and New_Stream_Procedure.
13726 (New_Stream_Function, New_Stream_Procedure): Removed.
13727 (Analyze_Attribute_Definition_Clause, case Address): Check new
13728 Alignment_Check check

13731 Javier Miranda <miranda@adacore.com>
13732 Robert Dewar <dewar@adacore.com>
13734 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
13735 generate the same errors compiling under -gnatc.
13736 (Try_Object_Operation): If no candidate interpretation succeeds, but
13737 there is at least one primitive operation with the right name, report
13738 error in call rather than on a malformed selected component.
13739 (Analyze_Selected_Component): If the prefix is an incomplete type from
13740 a limited view, and the full view is available, use the full view to
13741 determine whether this is a prefixed call to a primitive operation.
13742 (Operator_Check): Verify that a candidate interpretation is a binary
13743 operation before checking the type of its second formal.
13744 (Analyze_Call): Add additional warnings for function call contexts not
13746 (Analyze_Allocator): Move the check for "initialization not allowed for
13747 limited types" after analyzing the expression. This is necessary,
13748 because OK_For_Limited_Init looks at the structure of the expression.
13749 Before analysis, we don't necessarily know what sort of expression it
13750 is. For example, we don't know whether F(X) is a function call or an
13751 indexed component; the former is legal in Ada 2005; the latter is not.
13752 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
13753 were missing. We also didn't handle qualified expressions. Now also
13754 allow function calls. Use new common routine OK_For_Limited_Init.
13755 (Analyze_Type_Conversion): Do not perform some legality checks in an
13756 instance, because the error message will be redundant or spurious.
13757 (Analyze_Overloaded_Selected_Component): Do not do style check when
13758 setting an entity, since we do not know it is the right entity yet.
13759 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
13760 (Analyze_Overloaded_Selected_Component): Same change
13761 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
13762 since regular incomplete subtypes are transformed into corresponding
13763 subtypes of their full views.
13764 (Complete_Object_Operation): Treat name of transformed subprogram call
13765 as coming from source, for browsing purposes.
13766 (Try_Primitive_Operation): If formal is an access parameter, compare
13767 with base type of object to determine whether it is a primitive
13769 (Operator_Check): If no interpretation of the operator matches, check
13770 whether a use clause on any candidate might make the operation legal.
13771 (Try_Class_Wide_Operation): Check whether the first parameter is an
13772 access type whose designated type is class-wide.

13779 warn on infinite loops.
13780 Add \\ to some continuation messages
13781 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
13782 (Process_Bounds): If the bounds are integer literals that result from
13783 constant-folding, and they carry a user-defined type, preserve that type
13784 rather than treating this as an integer range.
13785 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
13786 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
13787 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
13788 left hand side of assignment.
13789 (Analyze_Assignment): Add suport to manage assigments to the attribute
13790 priority of a protected object.
13791 (Check_Possible_Current_Value_Condition): Allow fully qualified names
13792 not just identifiers.
13793 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
13794 or AND THEN for possible tracking.
13795 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
13796 case of while loops so we can track values in the loop body.

13799 Hristian Kirtchev <kirtchev@adacore.com>
13800 Bob Duff <duff@adacore.com>
13802 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
13803 procedure cannot be a protected operation (it is a basic_declaration,
13804 not a subprogram_declaration).
13805 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
13806 Subp. Add logic for entry processing.
13807 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
13808 Determine whether an entry or subprogram of a protected or task type
13809 override an inherited primitive of an implemented interface.
13810 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
13811 Update the actual used in calls to Check_Overriding_Indicator.
13812 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
13813 generate the proper reference to the parent unit, for cross-reference.
13814 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
13816 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
13817 (Add_Extra_Formal): Revise procedure to allow passing in associated
13818 entity, scope, and name suffix, and handle setting of the new
13819 Extra_Formals field.
13820 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
13821 pass new parameters. Add support for adding the new extra access formal
13822 for functions whose calls are treated as build-in-place.
13823 (Analyze_A_Return_Statement): Correct casing in error message.
13824 Move Pop_Scope to after Analyze_Function_Return, because an extended
13825 return statement really is a full-fledged scope. Otherwise, visibility
13826 doesn't work right. Correct use of "\" for continuation messages.
13827 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
13828 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
13829 the node doesn't get properly marked as analyzed.
13830 (Analyze_Subprogram_Body): If subprogram is a function that returns
13831 an anonymous access type that denotes a task, build a Master Entity
13833 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
13834 proper usage of null exclusion in a result definition.
13835 (Process_Formals): Code cleanup and new error message.
13836 (Process_Formals): Detect incorrect application of null exclusion to
13838 (Conforming_Types): Handle conformance between [sub]types and itypes
13839 generated for entities that have null exclusions applied to them.
13840 (Maybe_Primitive_Operation): Add an additional type retrieval when the
13841 base type is an access subtype. This case arrises with null exclusions.
13842 (New_Overloaded_Entity): Do not remove the overriden entity from the
13843 homonym chain if it corresponds with an abstract interface primitive.
13844 (Process_Formals): Replace membership test agains Incomplete_Kind with a
13845 call to the synthesized predicate Is_Incomplete_Type.
13846 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
13848 (Analyze_Subprogram_Declaration): Check that abstract interface
13849 primitives are abstract or null.
13850 (Analyze_Subprogram_Specification): Remove previous check for abstract
13851 interfaces because it was not complete.
13852 (Has_Interface_Formals): Removed.

13855 Javier Miranda <miranda@adacore.com>
13857 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
13858 of Analyze_Package_Body, to create Itype references for anonymous
13859 access types created in the package declaration, whose designated types
13860 may have only a limited view.
13861 (Analyze_Package_Specification): For the private part of a nested
13862 package, install private_with_clauses of enclosing compilation unit if
13863 we are in its visible part.
13864 (Declare_Inherited_Private_Subprograms): Complete barrier
13865 to ensure that the primitive operation has an alias to some parent
13866 primitive. This is now required because, after the changes done for the
13867 implementation of abstract interfaces, the contents of the list of
13868 primitives has entities whose alias attribute references entities of
13869 such list of primitives.
13870 (Analyze_Package_Specification): Simplify code that handles parent units
13871 of instances and formal packages.
13872 (Uninstall_Declarations): Check the convention consistency among
13873 primitive overriding operations of a tagged record type.

13877 Javier Miranda <miranda@adacore.com>
13878 Ed Schonberg <schonberg@adacore.com>
13880 * sem_ch8.adb: Minor error msg rewording
13881 (Undefined): When checking for misspellings, invert arguments (to get
13882 expected and found set right)
13883 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
13884 (Analyze_Generic_Renaming): Same fix
13885 (Use_One_Package): Do not take into account the internal entities of
13886 abstract interfaces during the analysis of entities that are marked
13887 as potentially use-visible.
13888 (Find_Type): Handle the case of an attribute reference for
13889 implementation defined attribute Stub_Type (simply let the analysis of
13890 the attribute reference rewrite it).
13891 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
13892 type that appears in a Use_Type clause.
13893 (Analyze_Object_Renaming): Add support for renaming of the Priority
13895 (Find_Type): In Ada 2005, a task type can be used within its own body,
13896 when it appears in an access definition.
13897 (Analyze_Object_Renaming): Remove warning on null_exclusion.
13898 (Analyze_Object_Renaming): Introduce checks for required null exclusion
13899 in a formal object declaration or in a subtype declaration.
13900 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
13901 (Check_Null_Exclusion): New local routine to
13902 Analyze_Subprogram_Renaming. Check whether the formals and return
13903 profile of a renamed subprogram have required null exclusions when
13904 their counterparts of the renaming already impose them.
13905 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
13906 Determine whether an entity is inside a generic scope.
13907 (In_Open_Scope): First pass of documentation update.
13908 (Find_Expanded_Name): Add support for shadow entities associated with
13909 limited withed packages. This is required to handle nested packages.
13910 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
13911 that makes a renaming of a limited withed package illegal.

13914 Ed Schonberg <schonberg@adacore.com>
13916 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
13917 Check_Overriding_Indicator.
13918 (Analyze_Task_Definition): Ditto.
13919 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
13920 (Check_Overriding_Indicator): To find overridden interface operation,
13921 examine only homonyms that have an explicit subprogram declaration, not
13922 inherited operations created by an unrelated type derivation.
13923 (Check_Overriding_Indicator): When checking for the presence of "null"
13924 in a procedure, ensure that the queried node is a procedure
13926 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
13927 type when the formal is an access to variable.
13928 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
13929 (Analyze_Task_Type): Same addition
13930 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
13931 provide navigation capabilities for entries.

13938 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
13939 inherited from an interface ancestor by another interface in the
13940 context of an instance as 'late'.
13941 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
13942 of a call to a function that dispatches on access result.
13943 (Check_Dispatching_Operation): In case of late overriding of a primitive
13944 that covers abstract interface subprograms we register it in all the
13945 secondary dispatch tables associated with abstract interfaces.
13946 (Check_Dispatching_Call): Add check that a dispatching call is not made
13947 to a function with a controlling result of a limited type. This is a
13948 current implementation restriction.
13949 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
13950 (Check_Dispatching_Operation): Do no emit a warning if the controlling
13951 argument is an interface type that is a generic formal.
13952 (Is_Interface_Subprogram): Removed.
13953 (Check_Dispatching_Operation): If the subprogram is not a dispatching
13954 operation, check the formals to handle the case in which it is
13955 associated with an abstract interface type.

13958 Ed Schonberg <schonberg@adacore.com>

13972 Hristian Kirtchev <kirtchev@adacore.com>
13973 Javier Miranda <miranda@adacore.com>
13975 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
13976 subprogram type to provide better diagnostics in case of ambiguity.
13977 (Covers): Handle coverage of formal and actual anonymous access types in
13978 the context of generic instantiation.
13979 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
13980 abstract interface types; this is required to handle concurrent types
13981 with discriminants and abstract interface types.
13982 (Covers): Include type coverage of both regular incomplete subtypes and
13983 incomplete subtypes of incomplete type visibles through a limited with

13995 Add missing continuation marks in error msgs
13996 (Unqualify): New function for removing zero or more levels of
13997 qualification from an expression. There are numerous places where this
13998 ought to be used, but we currently only deal properly with zero or one
14000 (In_Instance); The analysis of the actuals in the instantiation of a
14001 child unit is not within an instantiation, even though the parent
14002 instance is on the scope stack.
14003 (Safe_To_Capture_Value): Exclude the case of variables that are
14005 (Check_Obsolescent): Removed
14006 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
14007 is an aliased view, even when rewritten as a reference to the target
14008 object in an assignment.
14009 (Get_Subprogram_Entity): New function
14010 (Known_To_Be_Assigned): New function
14011 (Type_Access_Level): Compute properly the access level of a return

14018 has a null exclusion depending on its Nkind.
14019 Change Is_Lvalue to May_Be_Lvalue
14020 (May_Be_Lvalue): Extensive additional code to deal with subprogram
14021 arguments (IN parameters are not Lvalues, IN OUT parameters are).
14022 (Safe_To_Capture_Value): Extend functionality so it can be used for
14023 the current value condition case.
14024 (Has_Compatible_Alignment): New function
14025 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
14026 objects to handle the Ada 2005 case, where aliasedness no longer implies
14027 that the object is constrained. In particular, for dereferenced names,
14028 the designated object must be assumed to be unconstrained.
14029 (Kill_Current_Values): Properly deal with the case where we encounter
14030 a loop in the scope chain.
14031 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
14033 (Compile_Time_Constraint_Error): Improve error message in error case

14041 * s-osinte-tru64.adb:
14042 Mark Asm statements Volatile to prevent warnings (seems a
14043 reasonable change anyway)
14046 * s-mastop-irix.adb: Add Volatile to Asm statements
14047 Suppresses warning, and seems appropriate in any case
14049 * s-osinte-vms.adb: Add Volatile to Asm statement

14063 Private_Extension_Declaration to the list of assertions.
14064 (Is_Entry_Barrier_Function): New flag
14065 (Has_Self_Reference): New flag on aggregates, to indicate that they
14066 contain a reference to the enclosing type, inserted through a default
14068 (Next_Rep_Item): Move from Node4 to Node5.
14069 (Entity): Add this field for N_Attribute_Definition_Clause.
14070 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
14071 (N_Return_Object_Declaration): Remove this node kind. We now use
14072 N_Object_Declaration instead.
14073 (Actual_Designated_Subtype): Move to a different place to make room in
14074 N_Extended_Return_Statement.
14075 (Procedure_To_Call): Move to a different place to make room in
14076 N_Extended_Return_Statement.
14077 (Return_Type): Removed this field to make room in return statements
14079 (Return_Statement_Entity): New field in return statements, in part to
14080 replace Return_Type, and in part to support the fact that return
14081 statements are now pushed on the scope stack during semantic analysis.
14082 (Return_Object_Declarations): New field to support extended return
14084 (N_Extended_Return_Statement): New node for extended_return_statement
14086 (N_Return_Object_Declaration): New node for part of
14087 extended_return_statement nonterminal. Needed because all the necessary
14088 fields won't fit in N_Extended_Return_Statement.
14089 Generic_associations now carry the Box_Present flag, to indicate a
14090 default for an actual in a partially parametrized formal package.
14092 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
14093 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma
14094 and for the new predefined dispatching policies: EDF_Across_Priorities,

14096 Introduce new name Stub_Type for implementation defined attribute.
14097 Add pragma Preelaborable_Initialization
14098 Add entry for Priority attribute.

14107 * sprint.adb (Sprint_Node_Actual, case Parameter_Specification): Do not
14108 print null exclusion twice in the case of an access definition,
14109 Implement new -gnatL switch
14110 Remove N_Return_Object_Declaration. We now use
14111 N_Object_Declaration instead. Implement the case for
14112 N_Extended_Return_Statement. Alphabetize the cases.
14113 Add cases for new nodes N_Extended_Return_Statement and
14114 N_Return_Object_Declaration. The code is not yet written.
14115 Update the output for N_Formal_Object_Declaration
14116 and N_Object_Renaming_Declaration.
14117 (Write_Itype): Account for the case of a modular integer subtype whose

14688 Robert Dewar <dewar@adacore.com>
14690 * exp_ch4.adb (Expand_N_Allocator): If the allocated object is accessed
14691 through an access to class-wide interface we force the displacement of
14692 the pointer to the allocated object to reference the corresponding
14693 secondary dispatch table.
14694 (Expand_N_Op_Divide): Allow 64 bit divisions by small power of 2,
14695 if Long_Shifts are supported on the target, even if 64 bit divides
14696 are not supported (configurable run time mode).
14697 (Expand_N_Type_Conversion): Do validity check if validity checks on
14698 operands are enabled.
14699 (Expand_N_Qualified_Expression): Do validity check if validity checks
14700 on operands are enabled.

14711 the bounds of the type of the discriminant are not static expressions.
14713 * sem_aggr.adb (Check_Static_Discriminated_Subtype): Return false if
14714 the bounds of the discriminant type are not static.
14716 2006-02-17 Robert Dewar <dewar@adacore.com>
14718 * g-os_lib.adb (Copy_File): Make sure that if From has an Invalid_FD,
14719 then we close To if it is valid.
14721 2006-02-17 Vasiliy Fofanov <fofanov@adacore.com>
14723 * init.c (facility_resignal_table): new array
14724 (__gnat_default_resignal_p): enhance default predicate to resignal if
14725 VMS condition has one of the predefined facility codes.
14727 2006-02-17 Vasiliy Fofanov <fofanov@adacore.com>
14729 * Makefile.in: Use VMS64 specialized versions of several units in
14730 Interfaces.C hierarchy to be compatible with HP C default size choices.
14731 Use the default version of Ada.Synchronous_Task_Control for VxWorks 653.
14733 2006-02-17 Ed Schonberg <schonberg@adacore.com>
14735 * sem_ch10.adb (Analyze_With_Clause): If the unit is a subprogram
14736 instantiation, the corresponding entity is the related_instance of the
14737 wrapper package created for the instance.

14745 Ed Schonberg <schonberg@adacore.com>
14747 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
14748 type we cannot inherit the primitive operations; we inherit the
14749 Corresponding_Record_Type (which has the list of primitive operations).
14750 (Check_Anonymous_Access_Types): When creating anonymous access types for
14751 access components, use Rewrite in order to preserve the tree structure,
14753 (Analyze_Object_Declaration): For limited types with access
14754 discriminants with defaults initialized by an aggregate, obtain
14755 subtype from aggregate as for other mutable types.
14756 (Derived_Type_Declaration): If the derived type is a limited interface,
14757 set the corresponding flag (Is_Limited_Record is not sufficient).

14766 2006-02-17 Javier Miranda <miranda@adacore.com>
14768 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
14769 abstract interface type, the static analysis is not enough to know if
14770 the interface is implemented or not by the source tagged type. Hence
14771 we must pass the work to the expander to generate the required code to
14772 evaluate the conversion at run-time.
14773 (Resolve_Equality_Op): Do not apply previous
14774 transformation if expansion is disasbled, to prevent anomalies when
14775 locating global references in a generic unit.

14955 table to take advantage of the 16 priority levels available on Windows
14956 2000 and XP. On NT4 there are only 7 priority levels, this is properly
14957 supported by this new mapping.

15003 (Read): Change the implementation to support unicode characters. It is
15004 not possible to use strlen() on Windows as this version supports only
15005 standard ASCII characters. So the length of the directory entry is now
15006 returned from the imported __gnat_readdir routine.

15044 E_Floating_Point_Subtype>: Inherit alias set of what we are making a
15045 subtype of to ensure conflicts amongst all subtypes in a hierarchy,
15046 necessary since these are not different types and pointers may
15047 actually designate any subtype in this hierarchy.
15048 (gnat_to_gnu_entity, case E_Record_Type): Always make fields for
15049 discriminants but put them into record only if not Unchecked_Union;
15050 pass flag to components_to_record showing Unchecked_Union.
15051 (make_dummy_type): Use UNION_TYPE only if Unchecked_Union and no
15052 components before variants; don't set TYPE_UNCHECKED_UNION_P.

15054 Remove special case code for Unchecked_Union and instead use main code
15055 with small changes.
15058 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
15059 variable with the expression being built, only its inner field.

15062 emit_sequence_entry_statements.
15063 (emit_sequence_entry_statements, body_with_handlers_p): Delete.

15067 for a subprogram if it has a foreign convention or is exported.
15068 (Identifier_to_gnu): Manually unshare the DECL_INITIAL tree when it is
15069 substituted for a CONST_DECL.
15070 (tree_transform, case N_Aggregate): Remove code for UNION_TYPE and pass
15071 Etype to assoc_to_constructor.
15072 (assoc_to_constructor): New argument, GNAT_ENTITY; use it to ignore
15073 discriminants of Unchecked_Union.
15074 (TARGET_ABI_OPEN_VMS): Define to 0 if not defined, so that later uses
15075 don't need cluttering preprocessor directives.
15076 (establish_gnat_vms_condition_handler): New function. Establish the GNAT
15077 condition handler as current in the compiled function.
15078 (body_with_handlers_p): New function. Tell whether a given sequence of
15079 statements node is attached to a package or subprogram body and involves
15080 exception handlers possibly nested within inner block statements.
15081 (emit_sequence_entry_statements): New function, to emit special
15082 statements on entry of sequences when necessary. Establish GNAT
15083 condition handler in the proper cases for VMS.

15575 (Parent_Size): Modified to get access to the separate table of primitive
15576 operations or the parent type.
15577 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
15578 functionality of Set_Prim_Op_Address but applied to predefined primitive
15580 (Set_Signature): New subprogram used to store the signature of a DT.
15581 (Displace): If the Offset_To_Top value is not static then call the
15582 function generated by the expander to get such value; otherwise use
15583 the value stored in the table of interfaces.
15584 (Offset_To_Top): The type of the actual has been changed to Address to
15585 give the correct support to tagged types with discriminants. In this
15586 case this value is stored just immediately after the tag field.
15587 (Set_Offset_To_Top): Two new formals have been added to indicate if the
15588 offset_to_top value is static and hence pass this value to the run-time
15589 to store it in the table of interfaces, or else if this value is dynamic
15590 and then pass to the run-time the address of a function that is
15591 generated by the expander to provide this value for each object of the
15594 * rtsfind.ads (Default_Prin_Op_Count): Removed.
15595 (Default_Prim_Op_Count): New entity
15596 (Get_Predefined_Prim_Op_Address): New entity
15597 (Set_Predefined_Prim_Op_Address): New entity
15598 (RE_Set_Signature): New entity

15601 Ed Schonberg <schonberg@adacore.com>
15603 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
15604 Make_Adjust_Call done for a newly-allocated object.
15606 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
15607 in a subprogram are wrapped in a cleanup block, indicate that the
15608 subprogram contains an inner block with an exception handler.
15609 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
15610 Adjust call is for a newly-allocated object. In that case we must not
15611 assume that the finalization list chain pointers are correct (since they
15612 come from a bit-for-bit copy of the original object's pointers) so if
15613 the attach level would otherwise be zero (no change), we set it to 4
15614 instead to cause the pointers to be reset to null.
15616 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
15617 reset chain pointers to null.
15619 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15621 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
15622 string, and the context requires a loop for the assignment (e.g.
15623 because the left-hand side is packed), generate a unique name for the
15624 temporary that holds the string, to prevent spurious name clashes.
15626 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15627 Javier Miranda <miranda@adacore.com>
15628 Robert Dewar <dewar@adacore.com>
15629 Gary Dismukes <dismukes@adacore.com>
15631 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
15632 return unconstrained arrays.
15634 (Expand_Call): An indirect call through an access parameter of a
15635 protected operation is not a protected call.
15636 Add circuit to raise CE in Ada 2005 mode following call
15637 to Raise_Exception.
15638 (Register_DT_Entry): Do nothing if
15639 the run-time does not give support to abstract interfaces.
15640 (Freeze_Subprogram): In case of dispatching operations, do not generate
15641 code to register the operation in the dispatch table if the source
15642 is compiled with No_Dispatching_Calls.
15643 (Register_Predefined_DT_Entry): Generate code that calls the new
15644 run-time subprogram Set_Predefined_Prim_Op_Address instead of
15645 Set_Prim_Op_Address.
15647 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
15648 on array assignments if the right-hand side is a function call that has
15649 been inlined. Check is performed on the assignment in the block.
15650 (Process_Bounds): If bounds and range are overloaded, apply preference
15651 rule for root operations to disambiguate, and diagnose true ambiguity.
15652 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
15653 a tag-indeterminate right-hand side even when Expander_Active is True.
15654 Needed to ensure that dispatching calls to T'Input are allowed and
15655 get the tag of the target class-wide object.
15657 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
15658 an inherited primitive operation that already overrides several
15659 abstract interface primitives. For transitivity, the new entity must
15660 also override all the abstract interface primitives covered by the
15661 inherited overriden primitive.
15662 Emit warning if new entity differs from homograph in same scope only in
15663 that one has an access parameter and the other one has a parameter of
15664 a general access type with the same designated type, at the same
15665 position in the signature.
15666 (Make_Inequality_Operator): Use source locations of parameters and
15667 subtype marks from corresponding equality operator when creating the
15668 tree structure for the implicit declaration of "/=". This does not
15669 change anything in behaviour except that the decoration of the
15670 components of the subtree created for "/=" allows ASIS to get the
15671 string images of the corresponding identifiers.
15672 (Analyze_Return_Statement): Remove '!' in warning message.
15673 (Check_Statement_Sequence): Likewise.
15674 (Analyze_Subprogram_Body): For an access parameter whose designated type
15675 is an incomplete type imported through a limited_with clause, use the
15676 type of the corresponding formal in the body.
15677 (Check_Returns): Implicit return in No_Return procedure now raises
15678 Program_Error with a compile time warning, instead of beging illegal.
15679 (Has_Single_Return): Function returning unconstrained type cannot be
15680 inlined if expression in unique return statement is not an identifier.
15681 (Build_Body_To_Inline): It is possible to inline a function call that
15682 returns an unconstrained type if all return statements in the function
15683 return the same local variable. Subsidiary procedure Has_Single_Return
15684 verifies that the body conforms to this restriction.
15686 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
15687 same type, and one of them is of an anonymous access type, convert
15688 the other operand to it, so that this is a valid binary operation for
15690 (Resolve_Type_Conversion): Handle subtypes of protected types and
15691 task types when accessing to the corresponding record type.
15692 (Resolve_Allocator): Add '\' in 2-line warning message.
15693 Remove '!' in warning message.
15694 (Resolve_Call): Add '\' in 2-line warning message.
15695 (Valid_Conversion): Likewise.
15696 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
15697 resulting type may be an access type with an implicit dereference.
15698 Obtain the proper component from the designated type.
15699 (Make_Call_Into_Operator): Handle properly a call to predefined equality
15700 given by an expanded name with prefix Standard, when the operands are
15701 of an anonymous access type.
15702 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
15703 Explicit_Dereference and Resolve_Selected_Component, to verify that the
15704 prefix of the expression is not of an incomplete type. Allows full
15705 diagnoses of all semantic errors.
15706 (Resolve_Actuals): If the actual is an allocator whose directly
15707 designated type is a class-wide interface we build an anonymous
15708 access type to use it as the type of the allocator. Later, when
15709 the subprogram call is expanded, if the interface has a secondary
15710 dispatch table the expander will add a type conversion to force
15711 the displacement of the pointer.
15712 (Resolve_Call): If a function that returns an unconstrained type is
15713 marked Inlined_Always and inlined, the call will be inlined and does
15714 not require the creation of a transient scope.
15715 (Check_Direct_Boolean_Op): Removed
15716 (Resolve_Comparison_Op): Remove call to above
15717 (Resolve_Equality_Op): Remove call to above
15718 (Resolve_Logical_Op): Inline above, since this is only call.
15719 (Valid_Conversion): Handle properly conversions between arrays of
15720 convertible anonymous access types.
15723 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
15724 the literal in an unchecked conversion, because GCC 4.x needs a static
15725 value for a string bound.
15727 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15728 Hristian Kirtchev <kirtchev@adacore.com>
15730 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
15731 components of the corresponding record, take into account component
15732 definitions that are access definitions.
15733 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
15734 procedure is not considered a dispatching call and will be expanded
15737 2006-02-13 Javier Miranda <miranda@adacore.com>
15739 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
15740 controlling argument of the dispatching call is an abstract interface
15741 class-wide type then we use it directly.
15742 Check No_Dispatching_Calls restriction.
15743 (Default_Prim_Op_Position): Remove the code that looks for the last
15744 entity in the list of aliased subprograms. This code was wrong in
15746 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
15747 when the source is compiled with the No_Dispatching_Calls restriction.
15748 (Init_Predefined_Interface_Primitives): No need to inherit primitives
15749 if we are compiling with restriction No_Dispatching_Calls.
15750 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
15751 subprograms if we are compiling under No_Dispatching_Calls restriction.
15752 (Make_DT): Generate a dispatch table with a single dummy entry if
15753 we are compiling with the No_Dispatching_Calls restriction. In
15754 addition, in this case we don't generate code that calls to the
15755 following run-time subprograms: Set_Type_Kind, Inherit_DT.
15756 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
15757 of this subprogram if compiling with the No_Dispatching_Calls
15759 (Expand_Type_Conversion): Instead of using the actual parameter,
15760 the argument passed as parameter to the conversion function was
15761 erroneously referenced by the expander.
15762 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
15763 Set_Predefined_Primitive_Op_Address and Set_Signature.
15764 (Expand_Dispatching_Call): Generate call to
15765 Get_Predefined_Prim_Op_Address for predefined primitives.
15766 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
15767 predefined primitives.
15768 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
15769 primitives we reserve one dummy entry to ensure that the tag does not
15770 point to some memory that is associated with some other object. In
15771 addition, remove all the old code that generated the assignments
15772 associated with the signature of the dispatch table and replace them
15773 by a call to the new subprogram Set_Signature.
15774 (Set_All_DT_Position): Change the algorithm because now we have a
15775 separate dispatch table associated with predefined primitive operations.
15776 (Expand_Interface_Conversion): In case of non-static offset_to_top
15777 add explicit dereference to get access to the object after the call
15778 to displace the pointer to the object.
15779 (Expand_Interface_Thunk): Modify the generation of the actual used
15780 in the calls to the run-time function Offset_To_Top to fulfil its
15782 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
15784 2006-02-13 Ed Schonberg <schonberg@adacore.com>
15786 * exp_dist.adb (Copy_Specification): For access parameters, copy
15787 Null_Exclusion flag, which will have been set for stream subprograms
15790 2006-02-13 Pascal Obry <obry@adacore.com>
15792 * expect.c (__gnat_expect_portable_execvp): New implementation. The
15793 previous implementation was using the C runtime spawnve routine but
15794 the corresponding wait was using directly the Win32 API. This was
15795 causing some times a lock when waiting for an event using
15796 WaitForSingleObject in __gnat_waitpid. This new implementation uses
15797 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
15798 API fixes this problem.
15800 2006-02-13 Robert Dewar <dewar@adacore.com>
15802 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

15810 array reference that is an explicit dereference, mark the converted
15811 (packed) array reference as analyzed to prevent a forthcoming
15812 reanalysis from resetting its type to the original (non-packed) array

15816 Javier Miranda <miranda@adacore.com>
15817 Eric Botcazou <ebotcazou@adacore.com>
15819 * exp_util.ads, exp_util.adb (Find_Prim_Op,
15820 Is_Predefined_Primitive_Operation): When
15821 searching for the predefined equality operator, verify that operands
15822 have the same type.
15823 (Is_Predefined_Dispatching_Operation): Remove the code that looks
15824 for the last entity in the list of aliased subprograms. This code
15825 was wrong in case of renamings.
15826 (Set_Renamed_Subprogram): New procedure
15827 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
15828 Exp_Type constant computed when entering this subprogram.

15830 (OK_To_Do_Constant_Replacement): New function
15831 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
15832 (Side_Effect_Free): An attribute reference 'Input is not free of
15833 side effect, unlike other attributes that are functions. (from code
15835 (Remove_Side_Effects): Expressions that involve packed arrays or records
15836 are copied at the point of reference, and therefore must be marked as
15837 renamings of objects.
15838 (Is_Predefined_Dispatching_Operation): Return false if the operation is
15839 not a dispatching operation.
15842 (Remove_Side_Effects): Lift enclosing type conversion nodes for
15843 elementary types in all cases.

15848 task types when accessing to the corresponding record type.
15849 Remove '!' in warning message.
15851 2006-02-13 Olivier Hainque <hainque@adacore.com>
15853 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
15854 to avoid useless and space inefficient overalignments on targets where
15855 Max_Alignment is larger than 16.
15857 2006-02-13 Pascal Obry <obry@adacore.com>
15859 * g-catiio.adb (Sec_Number): New type used to compute the number of
15860 seconds since 1-1-1970.
15861 (Image) [Natural]: The parameter was an Integer, as we can't deal with
15862 negative numbers (years, months...) it is better to have a Natural here.
15864 (Image) [Number]: Change parameter from Long_Integer to Number.
15865 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
15866 overflow for dates past year 2038.
15868 2006-02-13 Matthew Heaney <heaney@adacore.com>
15870 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
15873 2006-02-13 Arnaud Charlet <charlet@adacore.com>
15875 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
15877 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
15878 finalization can occur normally.
15880 2006-02-13 Vincent Celier <celier@adacore.com>
15882 * gnatcmd.adb (Rules_Switches): New table
15883 (Add_To_Rules_Switches): New procedure
15884 (GNATCmd): For command CHECK, put all options following "-rules" in the
15885 Rules_Switches table. Append these -rules switches after the -cargs
15888 2006-02-13 Robert Dewar <dewar@adacore.com>
15890 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
15891 These two cases were generating incorrect output, and if this unit
15892 was built with checks on, generated a discriminant mismatch constraint

15896 Robert Dewar <dewar@adacore.com>
15898 * lib-xref.adb (Get_Type_Reference): For a private type whose full
15899 view is an array type, indicate the component type as well, for
15900 navigation purposes.

15902 of violating pragma Unreferenced.
15903 Do not give Ada 2005 warning except on real reference.

15907 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
15908 main source, add switch -mdebug-main=_ada_ so that the executable can
15909 be debugged by the standard VMS debugger.
15910 (Gnatmake): Set No_Main_Subprogram to True when there is no main
15911 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
15912 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
15913 of the last source, as the binding and linking phases are never
15915 Set all executable obsolete when rebuilding a library.
15917 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
15920 2006-02-13 Javier Miranda <miranda@adacore.com>
15923 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
15924 code to improve the error message reported when the program has
15925 declarations of abstract interface types and it is not compiled with
15926 the -gnat05 switch.
15927 (P_Access_Definition): Reorganize the code to improve the error
15928 message reported when the new Ada 2005 syntax for anonymous
15929 access types is used and the program is not compiled with the

15982 When removing nodes (attributes Source_Dirs, Source_Files,
15983 Source_List_File and package Naming), save the comments and attach the
15984 saved comments to the newly created nodes.
15985 Do not add a with clause for the naming package if one already exists.

16001 No_Return procedure with procedure that is not No_Return
16002 (Check_Dispatching_Call): Suppress the check for an abstract operation
16003 when the original node of an actual is a tag-indeterminate attribute
16004 call, since the attribute, which must be 'Input, can never be abstract.
16005 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
16006 call to the Input attribute (even when rewritten).
16007 (Propagate_Tag): Augment comment to indicate the possibility of a call
16008 to an Input attribute.
16010 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
16011 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
16013 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
16014 No_Wide_Characters is no longer partition-wide

16024 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
16025 handles default-initialized components to keep separate the management
16026 of this feature but also avoid the unrequired resolution and
16027 expansion of components that do not have partially initialized
16029 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
16030 (Check_Bounds): Likewise.
16031 (Check_Length): Likewise.
16033 2006-02-13 Javier Miranda <miranda@adacore.com>
16034 Ed Schonberg <schonberg@adacore.com>
16036 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
16037 abstract interface type call analyze_and_resolve to expand the type
16038 conversion into the corresponding displacement of the
16039 reference to the base of the object.
16040 (Eval_Attribute, case Width): For systems where IEEE extended precision
16041 is supported, the maximum exponent occupies 4 decimal digits.
16042 (Accessibility_Message): Add '\' in 2-line warning message.
16043 (Resolve_Attribute): Likewise.
16044 (case Attribute_Access): Significantly revise checks
16045 for illegal access-to-subprogram Access attributes to properly enforce
16046 the rules of 3.10.2(32/2).
16047 Diagnose use of current instance with an illegal attribute.
16049 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
16051 (Enclosing_Generic_Unit): New function to return a node's innermost
16052 enclosing generic declaration node.
16053 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
16054 (Type_Access_Level): The accessibility level of anonymous acccess types
16055 associated with discriminants is that of the current instance of the
16056 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
16057 (Compile_Time_Constraint_Error): Handle case of conditional expression.
16058 (Kill_Current_Values_For_Entity): New function
16059 (Enter_Name): Change formal type to Entity_Id

16063 Gary Dismukes <dismukes@adacore.com>
16065 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
16066 Analyze_Compilation_Unit.
16067 Detect and warn on redundant with clauses detected in a package spec
16068 and/or body when -gnatwr is used.
16069 (Analyze_Context): Analyze config pragmas before other items
16070 (Install_Context_Items): Don't analyze config pragmas here
16071 (Install_Limited_Withed_Unit): Set limited entity of package in
16072 with_clause so that cross-reference information or warning messages on
16073 unused packages can be properly generated
16074 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
16075 has Error_Posted set. Prevent infinite loops in illegal programs.
16076 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
16077 to the point of the error test requiring the current unit to be private.
16078 This ensures that private with clauses are not exempted from the basic
16079 checking for being a descendant of the same library unit parent as a
16080 withed private descendant unit.
16081 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
16082 handle private with clauses properly, as well as to account for cases
16083 where the withed unit is a public descendant of a private ancestor
16084 (in which case the current unit must be a descendant of the private
16085 ancestor's parent). The spec comments were updated accordingly. Also,
16086 the old error message in this subprogram was replaced with error
16087 messages that mirror the errors tested and reported by
16088 Check_Private_Child_Unit.
16089 Parameter and variable names improved for readability.
16090 (Install_Limited_Context_Clauses): Remove test for a withed unit being
16091 private as the precondition for calling
16092 Check_Private_Limited_Withed_Unit since that subprogram has been
16093 revised to test public units as well as private units.

16098 Javier Miranda <miranda@adacore.com>
16100 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
16101 that Scope_Stack.First = 1.
16102 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
16103 were not always properly handled previously.
16104 (Formal_Entity): Complete rewrite, to handle properly some complex case
16105 with multiple levels of parametrization by formal packages.
16106 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
16107 to the corresponding derived type declaration for proper semantics.
16109 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
16110 (Check_Component): Enforce restriction on components of
16111 unchecked_unions: a component in a variant cannot contain tasks or
16113 (Unchecked_Union): Allow nested variants and multiple discriminants, to
16115 Add pragma Ada_2005 (synonym for Ada_05)
16116 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
16117 were not always properly handled previously.
16118 Document that pragma Propagate_Exceptions has no effect
16119 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
16120 (Set_Convention_From_Pragma): Check that if a convention is
16121 specified for a dispatching operation, then it must be
16122 consistent with the existing convention for the operation.
16123 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
16124 longer required to specify an vtable-ptr component in the record. For
16125 compatibility reasons we leave the support for the previous definition.
16126 (Analyze_Pragma, case No_Return): Allow multiple arguments
16128 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
16129 non-overrideen inherited operation with a controlling result as
16130 illegal only its implicit declaration comes from the derived type
16131 declaration of its result's type.
16132 (Check_Possible_Deferred_Completion): Relocate the object definition
16133 node of the subtype indication of a deferred constant completion rather
16134 than directly analyzing it. The analysis of the generated subtype will
16135 correctly decorate the GNAT tree.
16136 (Record_Type_Declaration): Check whether this is a declaration for a
16137 limited derived record before analyzing components.
16138 (Analyze_Component_Declaration): Diagnose record types not explicitly
16139 declared limited when a component has a limited type.
16140 (Build_Derived_Record_Type): Code reorganization to check if some of
16141 the inherited subprograms of a tagged type cover interface primitives.
16142 This check was missing in case of a full-type associated with a private
16144 (Constant_Redeclaration): Check that the subtypes of the partial and the
16145 full view of a constrained deferred constant statically match.
16146 (Mentions_T): A reference to the current type in an anonymous access
16147 component declaration must be an entity name.
16148 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
16149 class_wide type to refer to full type, not to the incomplete one.
16150 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
16151 available. Required to give support to the certified run-time.
16152 (Analyze_Component_Declaration): In case of anonymous access components
16153 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
16154 (Process_Discriminants): For an access discriminant, use the
16155 discriminant specification as the associated_node_for_itype, to
16156 simplify accessibility checks.
16158 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16159 Javier Miranda <miranda@adacore.com>
16161 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
16162 abstract interpretations on an operator, remove interpretations that
16163 yield Address or a type derived from it, if one of the operands is an
16165 (Try_Object_Operation.Try_Primitive_Operation,
16166 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
16167 location when creating the new reference to a primitive or class-wide
16168 operation as a part of rewriting a subprogram call.
16169 (Try_Primitive_Operations): If context requires a function, collect all
16170 interpretations after the first match, because there may be primitive
16171 operations of the same type with the same profile and different return
16172 types. From code reading.
16173 (Try_Primitive_Operation): Use the node kind to choose the proper
16174 operation when a function and a procedure have the same parameter
16176 (Complete_Object_Operation): If formal is an access parameter and prefix
16177 is an object, rewrite as an Access reference, to match signature of
16178 primitive operation.
16179 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
16180 by an expanded name with prefix Standard, when the operands are of an
16181 anonymous access type.
16182 (Remove_Abstract_Operations): If the operation is abstract because it is
16183 inherited by a user-defined type derived from Address, remove it as
16184 well from the set of candidate interpretations of an overloaded node.
16185 (Analyze_Membership_Op): Membership test not applicable to cpp-class
16188 2006-02-13 Bob Duff <duff@adacore.com>
16190 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
16191 redundant use clauses.
16192 In particular, if the scope of two use clauses overlaps, but one is not
16193 entirely included in the other, we should not warn. This can happen
16194 with nested packages.
16195 (Analyze_Subprogram_Renaming): Protect the compiler against previously
16196 reported errors. The bug was reported when the compiler was built
16197 with assertions enabled.
16198 (Find_Type): If the node is a 'Class reference and the prefix is a
16199 synchronized type without a corresponding record, return the type
16202 2006-02-13 Javier Miranda <miranda@adacore.com>
16204 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
16205 if this is the full-declaration associated with a private declaration
16206 that implement interfaces, then the private type declaration must be
16208 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
16209 as aliased. The use of the 'access attribute is not available for such
16210 object (for this purpose the object should be explicitly marked as
16211 aliased, but being an anonymous type this is not possible).
16213 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16214 Robert Dewar <dewar@adacore.com>
16216 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
16217 compilation unit is an elaboration scope.
16218 (Add_Task_Proc): Add '\' in 2-line warning message.
16219 (Activate_All_Desirable): Deal with case of unit with'ed by parent
16221 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16222 Javier Miranda <miranda@adacore.com>
16224 * sem_type.adb (Write_Overloads): Improve display of candidate
16226 (Add_One_Interp): Do not add to the list of interpretations aliased
16227 entities corresponding with an abstract interface type that is an
16228 immediate ancestor of a tagged type; otherwise we have a dummy
16229 conflict between this entity and the aliased entity.
16230 (Disambiguate): The predefined equality on universal_access is not
16231 usable if there is a user-defined equality with the proper signature,
16232 declared in the same declarative part as the designated type.
16233 (Find_Unique_Type): The universal_access equality operator defined under
16234 AI-230 does not cover pool specific access types.
16235 (Covers): If one of the types is a generic actual subtype, check whether
16236 it matches the partial view of the other type.
16238 2006-02-13 Thomas Quinot <quinot@adacore.com>
16240 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
16241 line. This is necessary to allow In_Extended_Main_Unit to provide
16242 correct results for itypes while writing out expanded source.
16243 (Close_File): No need to update the source_index_table here since it's
16244 now done for each line.
16246 2006-02-13 Ed Schonberg <schonberg@adacore.com>
16247 Robert Dewar <dewar@adacore.com>
16249 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
16250 preserve the source unit where the itype is declared, and prevent a
16252 (Note_Implicit_Run_Time_Call): New procedure
16253 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
16256 * sprint.ads: Document use of $ for implicit run time routine call
16258 2006-02-13 Quentin Ochem <ochem@adacore.com>
16260 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
16263 2006-02-13 Bob Duff <duff@adacore.com>
16265 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
16266 Scan_Unsigned, so we do not scan leading blanks and sign twice.
16267 Integer'Value("- 5") and Integer'Value("-+5") now correctly
16268 raise Constraint_Error.
16270 * s-vallli.adb (Scan_Long_Long_Integer): Call
16271 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
16272 do not scan leading blanks and sign twice.
16273 Integer'Value("- 5") and Integer'Value("-+5") now correctly
16274 raise Constraint_Error.
16276 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
16277 Scan_Long_Long_Unsigned): Split out most of the processing from
16278 Scan_Long_Long_Unsigned out into
16279 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
16280 This prevents scanning leading blanks and sign twice.
16281 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
16284 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
16285 out most of the processing from Scan_Unsigned out into
16286 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
16287 This prevents scanning leading blanks and sign twice.
16289 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
16290 use with Modular'Value attribute.
16291 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
16294 2006-02-13 Robert Dewar <dewar@adacore.com>
16296 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value

16420 Ada bind file prefix on VMS from b$ to b__.
16422 * gnatlink.adb (Process_Args): Call Add_Src_Search_Dir for -I in
16423 --GCC so that Get_Target_Parameters can find system.ads.
16424 (Gnatlink): Call Get_Target_Parameters in mainline.
16425 Initialize standard packages for Targparm.
16426 Change some Hostparm.OpenVMS checks to Targparm.OpenVMS_On_Target.

16462 * osint.ads (Object_Suffix): Remove, no longer used.
16463 (Target_Object_Suffix): Initialize with target object suffix.
16465 * rident.ads: Add special exception to license.
16467 * targparm.adb (Get_Target_Parameters): Set the value of
16468 Multi_Unit_Index_Character after OpenVMS_On_Target gets its definitive
16470 (Get_Target_Parameters): Set OpenVMS_On_Target if openvms.

16489 * a-taster.ads, a-taster.adb: New files.
16491 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
16492 link to the version that does nothing. This way the task termination
16493 routine is not executed twice for the environment task when finishing
16494 because of an unhandled exception.
16496 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
16497 handler because of an unhandled exception.
16499 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
16500 System.Tasking.Utilities instead of that in System.Tasking.Stages.
16502 * s-finimp.adb (initialization code): Modify the soft link for the
16503 finalization of the global list instead of Adafinal.
16505 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
16506 non-tasking version of the soft link for task termination. We do
16507 nothing since if we are using the non-tasking version it
16508 means that the task termination functionality is not used.
16509 (Null_Finalize_Global_List): Add this null version for the procedure
16510 in charge of finalizing the global list for controlled objects.
16511 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
16512 instead for handling run-time termination in a more flexible way.
16513 (Adafinal_NT): This new procedure will take care of finalizing the
16514 global list for controlled objects if needed, but no tasking
16517 * s-tarest.adb (Task_Lock): Do not try to lock again the
16518 Global_Task_Lock if we already own it. Otherwise, we get blocked in
16519 some run-time operations.
16520 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
16521 until all nested locks have been released.
16522 (Task_Wrapper): Call the fall-back task termination handler. It

16530 moved to the Common_ATCB record.
16531 (Task_Lock): Global_Task_Lock_Nesting has been moved to the

16543 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
16544 for storing task termination handlers. In addition,
16545 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to

16562 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
16563 potentially blocking operations has been moved from
16564 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
16565 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass

16618 (Displace): New subprogram that displaces the pointer to the object
16619 to reference one of its secondary dispatch tables.
16620 (IW_Membership): Modified to use the new table of interfaces.
16621 (Inherit_TSD): Modified to use the new table of interfaces.

16641 record component containing the tag of the secondary dispatch table we
16642 have to use the Offset_To_Top run-time function to get this information;
16643 otherwise if the pointer to the base of the object has been displace
16644 we get a wrong value if we use the 'position attribute.
16646 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
16647 all the calls to Expand_Interface_Thunk.

16682 RE_TK_Tagged, RE_TK_Task.
16684 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
16685 Init_Secondary_Tags_Internal to allow its use with interface types and
16686 also to generate the code for the new additional actual required
16687 by Set_Offset_To_Top.
16688 (Build_Init_Statements): In case of components associated with abstract
16689 interface types there is no need to generate a call to its IP.

16701 properly protected objects and attach handler in the case of the
16702 restricted profile.

16716 pointer initialization values. Make a SAVE_EXPR instead. Add comments
16717 about the use and expansion of SAVE_EXPRs in the various possible
16718 renaming handling cases.
16719 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
16720 abusing DECL_FCONTEXT.

16890 are implemented by the ancestors.
16891 (Derived_Type_Declaration): If the parent of the full-view is an
16892 interface perform a transformation of the tree to ensure that it has
16893 the same parent than the partial-view. This simplifies the job of the

16895 needed because the list of interfaces of the full-view can be given in
16897 (Process_Full_View): The parent of the full-view does not need to be
16898 a descendant of the parent of the partial view if both parents are
16900 (Analyze_Private_Extension_Declaration): If declaration has an explicit
16901 "limited" the parent must be a limited type.

16978 attributes are visible at the point of the subprogram declaration.
16979 For Ada 2005, the error message is modified to indicate that the

17012 types use the corresponding record type. This was not needed before
17013 the implementation of Ada 2005 synchronized types because
17014 concurrent types were never tagged types in Ada 95.
17016 2005-12-09 Ed Schonberg <schonberg@adacore.com>
17018 * sem_ch9.adb (Analyze_Delay_Alternative, Analyze_Delay_Until): Use the

17140 2005-11-21 Joel Sherrill <joel.sherrill@oarcorp.com>
17142 * socket.c: Add extern int h_errno for rtems since networking header
17143 files are not available at this point in a tool bootstrap. Newlib
17144 only has basic C library header files.

17147 Roger Sayle <roger@eyesopen.com>
17150 * misc.c (internal_error_function): Don't use vsprintf to format

17237 * gen-soccon.c: Complete value expansion should not be performed on
17238 TARGET, as it has the form of a math expression, and some components
17239 may be platform-defined macros.
17240 For VxWorks, generate the OK and ERROR values.
17241 New constants giving the sizes of the components of C struct timeval.

17253 deal with different cases of static and dynamic elaboration checks (all
17254 checks does not count in the first case, but does in the second).

17260 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
17261 elementary types using the operator in standard. It is cleaner not to
17262 modify the programmers intent, especially in the case of floating-point.
17263 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
17264 it did not matter because we always rewrote a/=b to not(a=b).
17265 (Expand_Allocator_Expression): For an allocator expression whose nominal
17266 subtype is an unconstrained packed type, convert the expression to its
17267 actual constrained subtype.
17268 Implement warning for <= or >= where < or > not possible
17269 Fix to Vax_Float tests (too early in many routines, causing premature
17270 Vax_Float expansions.
17272 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
17273 to be used with packages and generic packages as well as with

17276 of pragma Suppress (All_Checks)
17277 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
17278 a string literal for precise control over warnings.

17288 Allow optional = after -gnatm
17289 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
17290 longer sets Elaboration_Checks.
17291 Code to set warning mode moved to Sem_Warn
17292 so that it can be shared by pragma processing.
17294 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
17297 * s-taprop-solaris.adb:
17298 Change some <= to =, to avoid new warning

17304 2005-11-14 Robert Dewar <dewar@adacore.com>
17306 * exp_vfpt.adb: Handle /= case
17307 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
17308 so that we do not get duplicate scaling for fixed point conversions.
17310 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
17312 2005-11-14 Matthew Gingell <gingell@adacore.com>
17314 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
17315 Increase default priority on Lynx from 15 to 17, and meet the Ada
17316 requirement that Default_Priority be ((Priority'First +
17317 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

17414 from a fat or thin pointer type and a constrained object type.
17415 (annotate_value): Handle BIT_AND_EXPR.
17416 (annotate_rep): Don't restrict the back annotation of inherited
17417 components to the type_annotate_only case.
17418 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
17419 we are not defining the type.
17420 <E_Record_Type>: Likewise.
17421 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
17422 to get advantage of the new maybe_stabilize_reference interface, to
17423 ensure that what we reference is indeed stabilized instead of relying
17424 on assumptions on what the stabilizer does.
17425 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
17426 type imported through a limited_with clause, use its non-limited view.
17427 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
17429 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
17430 of #if sections + explicit comparisons of convention identifiers.
17431 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
17432 before early-returning for certain types when code generation is
17434 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
17435 nullification of gnu_expr we do for objects with address clause and
17436 that we are not defining.
17437 (elaborate_expression_1): Do not create constants when creating
17438 variables needed by the debug info: the dwarf2 writer considers that
17439 CONST_DECLs is used only to represent enumeration constants, and emits
17441 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
17442 object with an address clause into an indirect reference, drop the
17443 initializing expression.
17445 (STACK_CHECK_BUILTIN): Delete.
17446 (STACK_CHECK_PROBE_INTERVAL): Likewise.

17454 if there is an actual subtype provided by the front-end, use that
17455 subtype to build an actual type with bounds template.
17456 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
17457 is provided by the front-end, use that subtype to compute the size of
17458 the deallocated object.
17459 (gnat_to_gnu): When adding a statement into an elaboration procedure,
17460 check for a potential violation of a No_Elaboration_Code restriction.
17461 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
17462 with extra arguments to control whether to recurse through non-values
17463 and to let the caller know if the stabilization has succeeded.
17464 (gnat_stabilize_reference): Now a simple wrapper around
17465 maybe_stabilize, for common uses without restriction on lvalues and
17466 without need to check for the success indication.
17467 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
17468 pass false instead of 0 as the FORCE argument which is a bool.
17469 (Identifier_to_gnu): Remove checks ensuring that an renamed object
17470 attached to a renaming pointer has been properly stabilized, as no such
17471 object is attached otherwise.
17472 (call_to_gnu): Invoke create_var_decl to create the temporary when the
17473 function uses the "target pointer" return mechanism.
17474 Reinstate conversion of the actual to the type of the formal
17475 parameter before any other specific treatment based on the passing
17476 mechanism. This turns out to be necessary in order for PLACEHOLDER
17477 substitution to work properly when the latter type is unconstrained.
17479 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
17481 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
17482 with extra arguments to control whether to recurse through non-values
17483 and to let the caller know if the stabilization has succeeded.
17485 * utils2.c (gnat_build_constructor): Only sort the fields for possible
17486 static output of record constructor if all the components are constant.
17487 (gnat_build_constructor): For a record type, sort the list of field
17488 initializers in increasing bit position order.
17489 Factor common code to build a storage type for an unconstrained object
17490 from a fat or thin pointer type and a constrained object type.
17491 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
17492 types variants, and process special cases of VIEW_CONVERT expressions
17493 as their NOP_EXPR counterpart to ensure we get to the

17700 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
17701 'Terminated for task interface class-wide objects. Generate a call to
17702 the predefined dispatching routine used to retrieve the _task_id from

17732 the return value into its actual subtype in order to help the backend

17763 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

17783 attribute of the N_Free_Statement.
17784 Generate itype for classwide designated object in both cases of

17976 Do not give obsolescent warning on with of subprogram (since we
17978 (Analyze_With_Clause): Add test for obsolescent package
17979 (Install_Context_Clauses): If the unit is the body of a child unit, do
17980 not install twice the private declarations of the parents, to prevent
17981 circular lists of Use_Clauses in a parent.
17982 (Implicit_With_On_Parent): Do add duplicate with_clause on parent when
17983 compiling body of child unit.
17984 Use new class N_Subprogram_Instantiation
17985 (Expand_With_Clause): If this is a private with_clause for a child unit,
17986 appearing in the context of a package declaration, then the implicit
17987 with_clauses generated for parent units are private as well.

17996 in the actual package.
17997 (Analyze_Formal_Package): Move the setting of the formal package spec's
17998 Generic_Parent field so that it occurs prior to analyzing the package,
17999 to allow proper operation of Install_Parent_Private_Declarations.
18000 (Analyze_Package_Instantiation): Set the instantiated package entity's
18001 Package_Instantiation field.
18002 (Get_Package_Instantiation_Node): Move declaration to package spec.
18003 Retrieve the N_Package_Instantiation node when the Package_Instantiation
18005 (Check_Generic_Child_Unit): Within an inlined call, the only possible
18006 instantiation is Unchecked_Conversion, for which no parents are needed.
18007 (Inline_Instance_Body): Deinstall and record the use_clauses for all
18008 parent scopes of a scope being removed prior to inlining an instance
18010 (Analyze_Package_Instantiation): Do not perform front-end inlining when
18011 the current context is itself an instance within a non-instance child
18012 unit, to prevent scope stack errors.
18013 (Save_References): If the node is an aggregate that is an actual in a
18014 call, rewrite as a qualified expression to preserve some type
18015 information, to resolve possible ambiguities in the instance.
18016 (Instance_Parent_Unit): New global variable to record the ultimate
18017 parent unit associated with a generic child unit instance (associated
18018 with the existing Parent_Unit_Visible flag).

18025 not already set. Replace test of Is_Child_Unit with test of parent's
18026 scope against package Standard. Add comments and a ??? comment.
18027 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
18028 on a child instance parent to test that the parent equals

18043 * sem_ch3.ads, sem_ch3.adb (Build_Discriminal): Add link to original
18045 (Build_Private_Derived_Type): The entity of the created full view of the
18046 derived type does not come from source. If after installing the private
18047 declarations of the parent scope the parent is still private, use its
18048 full view to construct the full declaration of the derived type.
18049 (Build_Derived_Record_Type): Relax the condition that controls the
18050 execution of the check that verifies that the partial view and
18051 the full view agree in the set of implemented interfaces. In
18052 addition, this test now only takes into account the progenitors.
18053 (Derive_Interface_Subprograms): No need to derive subprograms
18054 of ancestors that are interfaces.

18059 view is a transitive derivation of the ancestor of the partial view.
18060 (Process_Full_View): Rename local subprogram Find_Interface_In_
18061 Descendant to Find_Ancestor_Interface to leave the code more clear.
18062 Remove wrong code that avoids the generation of an error message
18063 when the immediate ancestor of the partial view is an interface.
18064 In addition some minor reorganization of the code has been done to
18065 leave it more clear.
18066 (Analyze_Type_Declaration): If type has previous incomplete tagged
18067 partial view, inherit properly its primitive operations.
18068 (Collect_Interfaces): Make public, for analysis of formal

18080 and derived protected types, the parent may be an interface that must
18081 be included in the interface list.
18082 (Access_Definition): If the designated type is an interface that may
18083 contain tasks, create Master_Id for it before analyzing the expression
18084 of the declaration, which may be an allocator.
18085 (Record_Type_Declaration): Set properly the interface kind, for use
18086 in allocators, the creation of master id's for task interfaces, etc.

18094 appear immediately after a subprogram body, when there is no previous
18095 subprogram declaration.
18096 Change name Is_Package to Is_Package_Or_Generic_Package
18097 (Process_Formals): A non null qualifier on a non null named access
18098 type is not an error, and is a warning only if Redundant_Constructs

18104 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
18105 nested within Analyze_Package_Specification to install the private
18106 declarations and use clauses within each of the parent units of a
18107 package instance of a generic child package.

18109 package associated with a generic instance or formal package, the
18110 private declarations of the parent must be installed (by calling new
18111 procedure Install_Parent_Private_Declarations).
18112 Change name Is_Package to Is_Package_Or_Generic_Package
18113 (Preserve_Full_Attributes): For a synchronized type, the corresponding
18114 record is absent in a generic context, which does not indicate a

18119 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
18120 not try to rewrite a renamed stream attribute, because the operations
18121 on the type may not have been generated.
18122 Handle properly a renaming_as_body generated for a stream operation
18123 whose default is abstract because the object type itself is abstract.
18124 (Find_Type): If the type is incomplete and appears as the prefix of a
18125 'Class reference, it is tagged, and its list of primitive operations
18126 must be initialized properly.
18127 (Chain_Use_Clauses): When chaining the use clauses that appear in the
18128 private declaration of a parent unit, prior to compiling the private
18129 part of a child unit, find on the scope stack the proper parent entity
18130 on which to link the use clause.
18131 (Note_Redundant_Use): Emit a warning when a redundant use clause is
18133 (Analyze_Object_Renaming): An attribute reference is not a legal object

18151 a procedure call is used as a select statement trigger and is not an
18152 entry renaming or a primitive of a limited interface.
18153 (Valid_Conversion): If the operand has a single interpretation do not
18154 remove address operations.
18155 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
18156 statement to inhibit warning.
18157 (Resolve_Unary_Op): Do not produce a warning when
18158 processing an expression of the form -(A mod B)
18159 Use Universal_Real instead of Long_Long_Float when we need a high
18160 precision float type for the generated code (prevents gratuitous
18161 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
18162 (Resolve_Concatenation_Arg): Improve error message when argument is an
18163 ambiguous call to a function that returns an array.
18164 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
18165 there is an implicit operator in the given scope if we are within an
18166 instance: legality check has been performed on the generic.

18748 (Expand_Allocator_Expression): Add tests for suppression of the AI-344
18749 check for proper accessibility of the operand of a class-wide allocator.
18750 The check can be left out if checks are suppressed or if the expression

19106 * checks.adb (Check_Needed): New procedure, deals with removing checks
19107 based on analysis of short-circuited forms. Also generates warnings for
19108 improper use of non-short-circuited forms.

19124 (Error_Msg_Warn): New variable for < insertion char.
19125 * prj-nmsc.adb: Implement new errout insertion char < (conditional
19127 (Check_For_Source): Change value of Source_Id only after the current
19128 source has been dealt with.
19130 2005-09-01 Robert Dewar <dewar@adacore.com>
19131 Doug Rupp <rupp@adacore.com>
19133 * exp_attr.adb: Handle vax fpt for 'Valid attribute

19139 Hristian Kirtchev <kirtchev@adacore.com>
19140 Javier Miranda <miranda@adacore.com>
19142 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
19143 from object notation, the original node is unanalyzed and carries no
19144 semantic information, so that accessiblity checks must be performed on
19145 the type of the actual itself.
19146 (Expand_N_Subprogram_Declaration): Change last actual parameter for
19147 compatibility with Build_Protected_Sub_Specification.
19148 (Check_Overriding_Inherited_Interfaces): Add suport to handle
19149 overloaded primitives.
19150 (Register_Interface_DT_Entry): Use the new name of the formal
19151 the the calls to Expand_Interface_Thunk

19154 include the generation of dispatching subprograms when the type
19155 implements at least one interface.
19157 * lib.ads: Extend information in Load_Stack to include whether a given
19158 load comes from a Limited_With_Clause.
19160 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
19161 whether a potential circularity is harmless, because it includes units
19162 loaded through a limited_with clause. Extends previous treatment which
19163 did not handle properly arbitrary combinations of limited and
19164 non-limited clauses.
19166 2005-09-01 Nicolas Setton <setton@adacore.com>
19168 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
19169 to be encoded as typ___XBLU_lowerbound__upperbound instead of
19170 typ___XB_lowerbound__upperbound.
19172 2005-09-01 Thomas Quinot <quinot@adacore.com>
19174 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
19175 dummy access formal for RACW/RAS TypeCode TSS.
19176 (Build_TypeCode_Call): Do not generate dummy null access actual for
19177 calls to the TypeCode TSS.
19179 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19181 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
19182 fully qualified name, to distinguish instances with the same local name.

19196 (Close): Deallocate any existing filter for the concerned connection
19198 2005-09-01 Laurent Pautet <pautet@adacore.com>
19200 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
19201 position set is provided, we compute one in order to reduce the maximum
19202 length of the keys. This computation first selects a character
19203 position between 1 and the minimum length of the keys in order to
19204 avoid reducing one of the keys to an empty string.
19205 (Initialize, Compute): When the ratio V to K is too low, the algorithm
19206 does not converge. The initialization procedure now comes with a
19207 maximum number of iterations such that when exceeded, an exception is
19208 raised in Compute. The user can initialize this ratio to another value
19210 Reformating and updated headers.
19212 2005-09-01 Javier Miranda <miranda@adacore.com>
19214 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
19215 that given an entity T creates and returns an Itype that duplicates the
19216 contents of T. The returned Itype has the null-exclusion
19217 attribute set to True, and its Etype attribute references T
19218 to keep the association between the two entities.
19219 Update copyright notice
19221 * sem_aggr.adb (Check_Can_Never_Be_Null,
19222 Aggregate_Constraint_Checks, Resolve_Aggregate,
19223 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
19225 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

19228 Robert Dewar <dewar@adacore.com>
19229 Hristian Kirtchev <kirtchev@adacore.com>

19237 (P_Subprogram_Specification): Add parsing of anonymous access result
19238 plus null exclusions. Call Set_Result_Definition instead of
19241 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
19242 (P_Access_Type_Definition): Add parsing for an anonymous access result
19243 subtype, plus parsing for null exclusions. Call Set_Result_Definition
19244 instead of Set_Subtype_Mark.
19246 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
19247 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
19248 (Result_Definition): New function for N_Function_Specifications.
19249 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
19250 N_Function_Specification.
19251 (Set_Null_Exclusion_Present): Allow this flag for
19252 N_Function_Specification.
19253 (Set_Result_Definition): New procedure for N_Function_Specifications.
19254 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
19255 and N_Function_Specification.
19257 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
19258 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
19259 Add support for LIMITED NEW for Ada 2005 AI-419
19260 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
19261 syntax for anonymous access results.
19262 Replace Subtype_Mark field by Result_Definition in
19263 N_Function_Specification and N_Access_Definition specs.
19264 Add Null_Exclusion_Present to spec of N_Function_Specification.
19265 (Result_Definition): New function for N_Function_Specification and
19266 N_Access_Function_Definition.
19267 (Set_Result_Definition): New procedure for N_Function_Specification and
19268 N_Access_Function_Definition.
19270 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
19271 Result_Definition for cases of N_Access_Function_Definition and
19272 N_Function_Specification.
19273 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
19275 2005-09-01 Vincent Celier <celier@adacore.com>
19277 * lib-writ.adb: Update Copyright notice
19278 (Write_With_Lines): On platforms where file names are case-insensitive,
19279 record the file names in lower case.
19280 (Write_ALI): For D lines, on platforms where file names are
19281 case-insensitive, record the file names in lower case.
19283 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19284 Emmanuel Briot <briot@adacore.com>
19286 * lib-xref.adb (Output_Overridden_Op): Display information on
19287 overridden operation.

19295 overriding entity information.
19297 2005-09-01 Vincent Celier <celier@adacore.com>
19299 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
19300 including those that are inherited.
19302 2005-09-01 Robert Dewar <dewar@adacore.com>
19304 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
19306 * par-prag.adb: Implement new pragma Debug_Policy
19308 * sem_prag.adb Implement new pragma Debug_Policy
19309 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
19310 Component_Size attribute specification. Give warning for ignored pragma
19313 * snames.h, snames.ads, snames.adb: Introduce entries in
19314 Preset_Names for Name_Disp_Asynchronous_Select,
19315 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
19316 Name_Disp_Timed_Select.
19317 New pragma Debug_Policy
19319 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
19321 Switch -gnata also sets Debug_Pragmas_Enabled
19323 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
19324 handle an explicit -gnata when compiling predefined files.
19326 2005-09-01 Vincent Celier <celier@adacore.com>
19328 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
19329 directories of projects that have no Ada sources.
19331 2005-09-01 Robert Dewar <dewar@adacore.com>
19333 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
19334 (makes a difference for wide characters)
19336 * widechar.adb, widechar.ads:
19337 Add Wide_Char_Byte_Count feature to count chars vs bytes
19339 2005-09-01 Thomas Quinot <quinot@adacore.com>
19340 Ed Schonberg <schonberg@adacore.com>
19341 Robert Dewar <dewar@adacore.com>
19343 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
19344 'Address attribute reference with an overloaded prefix, use the
19345 location of the prefix (not the location of the attribute reference) as
19346 the error location.
19347 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
19348 a function renaming thereof, is a valid prefix for 'Size (where it is
19349 intepreted as a function call).
19350 (Statically_Denotes_Entity): New predicate to determine whether the
19351 prefix of an array attribute can be considered static.
19354 (Eval_Attr): Fix failure to evaluate Component_Size for
19355 unconstrained arrays (resulted in wrong value in packed case, since
19356 back end cannot handle this case)
19358 2005-09-01 Robert Dewar <dewar@adacore.com>
19360 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
19361 error msgs for most common cases.
19362 Use new errout insertion char < (conditional warning)
19364 2005-09-01 Javier Miranda <miranda@adacore.com>
19365 Ed Schonberg <schonberg@adacore.com>
19367 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
19368 become local to the whole package.
19369 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
19370 the package was already analyzed the new algorithm "replaces" the
19371 real entities by the shadow ones. This is required to ensure that
19372 the order of these entities in the homonym chains does not change;
19373 otherwise we can have undefined references at linking time because
19374 in case of conflicts the external name of the entities will have
19375 a suffix that depends on the order of the entities in the chain.
19376 (Remove_Limited_With_Clause): Complementary code that completes the
19377 new algorithm and replaces the shadow entities by the real ones.
19378 (Install_Limited_Withed_Unit): When unchaining entities before the
19379 installation of the shadow entities, only regular entities of the
19380 public part must be taken into account. This is required to
19381 keep this routine in synch with the work done by Remove_Limited_
19383 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
19384 even if unit is analyzed, because the analysis of the unit is
19385 idempotent in any case, and the limited view of the unit may have to
19386 be installed for proper visibility.
19387 (Expand_Limited_With_Clause): Even if the unit in the implicit
19388 with_clause has been analyzed already, a limited view of the package
19389 must be built for the current context, if it does not exist yet.
19391 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19392 Javier Miranda <miranda@adacore.com>
19393 Gary Dismukes <dismukes@adacore.com>
19395 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
19396 defining entity for the instance body, make a new defining identifier
19397 rather than copying the entity of the spec, to prevent accidental
19398 sharing of the entity list.
19399 (Check_Private_View): When exchanging views of private types, build the
19400 list of exchanged views as a stack, to ensure that on exit the exchanges
19401 are undone in the proper order.
19402 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
19403 Restore the compilation environment in case of instantiation_error.
19404 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
19405 for an anonymous access result.
19406 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
19407 (Formal_Entity): Handle properly the case of a formal package that
19408 denotes a generic package renaming.
19410 2005-09-01 Thomas Quinot <quinot@adacore.com>
19412 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
19413 clause if the array aggregate is surrounded by parentheses.
19415 2005-09-01 Cyrille Comar <comar@adacore.com>
19416 Gary Dismukes <dismukes@adacore.com>
19417 Ed Schonberg <schonberg@adacore.com>
19418 Javier Miranda <miranda@adacore.com>
19420 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
19422 to check if a type is Constrained in cases related to code generation
19423 (rather than semantic checking) since otherwise we do not generate
19424 similar code for mutable private types depending if their
19425 discriminants are visible or not.
19426 (Check_Abstract_Overriding): Do not complain about failure to override
19427 the primitive operations used in dispatching selects since they will
19428 always be overriden at the freeze point of the type.
19429 (Access_Definition): Separate out handling for resetting the scope
19430 of an anonymous access function result type. Retrieve the scope
19431 of the associated function rather than using Current_Scope, which
19432 does not have a consistent value (depends on whether we're in the
19433 middle of analyzing formal parameters). Add ??? comment about
19434 finding a cleaner way to handle the special cases of scope setting.
19435 (Process_Incomplete_Dependents): A protected operation is never a
19436 dispatching operation (only its wrapper may be).
19437 (Build_Derived_Record_Type): In case of tagged private types that
19438 implement interfaces add derivation of predefined primitive
19440 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
19441 by two parameters that are used in case of derivation from abstract
19442 interface types: No_Predefined_Prims is used to avoid the derivation
19443 of predefined primitives from the interface, and Predefined
19444 Prims_Only is used to complete the derivation predefined primitives
19445 in case of private tagged types implementing interfaces.
19446 Fix typo in comments
19447 (Find_Interface_In_Descendant): Protect the frontend against
19448 wrong code with large circularity chains.
19449 (Is_Private_Overriding): Add support for entities overriding interface
19450 subprograms. The test failed because Entities associated with overriden
19451 interface subprograms are always marked as hidden (and used to build
19452 the secondary dispatch table); in this case the overriden entity is
19453 available through the field abstract_interface_alias (cf. override_
19454 dispatching_operation)
19455 (Access_Definition): Set the scope of the type to Current_Scope for the
19456 case of a function with an anonymous access result type.
19457 (Access_Subprogram_Declaration): Handle creation of the type entity for
19458 an access-to-function type with an anonymous access result.
19459 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
19460 in handling for N_Access_Function_Definition.
19461 (Analyze_Subtype_Declaration): Modify the text of error message.
19462 (Derived_Type_Declaration): Modify the text of error message.
19463 (Process_Subtype): Modify the text of error message plus cleanup
19464 of one redundant error message.
19465 (Analyze_Component_Declaration): Code cleanup.
19466 (Analyze_Object_Declaration): Code cleanup.
19467 (Analyze_Subtype_Declaration): Propagate the null-exclusion
19468 attribute in case of access types. Code cleanup.
19469 (Array_Type_Declaration): Code cleanup.
19470 (Process_Discriminants): Create the new null-excluding itype
19471 if required. Code cleanup.
19472 (Process_Subtype): Create the new null-excluding itype if
19473 required. Code cleanup.
19474 (Build_Derived_Record_Type): Code cleanup to avoid calling
19475 twice the subprogram derive_subprograms in case of private
19476 types that implement interfaces. In this particular case the
19477 subprogram Complete_Subprograms_Derivation already does the
19478 job associated with the second call.
19480 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
19481 conversion to the full view when generating an operation for a
19482 discriminant whose type may currently be private.
19484 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19485 Javier Miranda <miranda@adacore.com>
19487 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
19488 V (Obj.F), the rewriting does not involve the indexed component, but
19489 only the selected component itself.
19490 Do not apply the transformation if the analyzed node is an actual of a
19491 call to another subprogram.
19492 (Complete_Object_Operation): Retain the entity of the
19493 dispatching operation in the selector of the rewritten node. The
19494 entity will be used in the expansion of dispatching selects.
19495 (Analyze_One_Call): Improve location of the error message associated
19497 (Analyze_Selected_Component): No need to resolve prefix when it is a
19498 function call, resolution is done when parent node is resolved, as
19500 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
19501 when attempting to resolve a call transformed from its object notation.
19502 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
19503 of the argument list for each interpretation of the operation.
19504 (Try_Object_Operation): The designated type of an access parameter may
19505 be an incomplete type obtained through a limited_with clause, in which
19506 case the primitive operations of the type are retrieved from its full
19508 (Analyze_Call): If this is an indirect call, and the return type of the
19509 access_to_subprogram is incomplete, use its full view if available.
19511 2005-09-01 Javier Miranda <miranda@adacore.com>
19512 Gary Dismukes <dismukes@adacore.com>
19514 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
19515 access types the null-exclusion and access-to-constant attributes must
19517 (Analyze_Return_Statement): When the result type is an anonymous access
19518 type, apply a conversion of the return expression to the access type
19519 to ensure that appropriate accessibility checks are performed.
19520 (Analyze_Return_Type): For the case of an anonymous access result type,
19521 generate the Itype and set Is_Local_Anonymous_Access on the type.
19522 Add ??? placeholder for check to disallow returning a limited object
19523 in Ada 2005 unless it's an aggregate or a result of a function call.
19524 Change calls from Subtype_Mark to Result_Definition.
19525 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
19526 Result_Definition in call to Make_Function_Specification.
19527 (Build_Body_To_Inline): Change Set_Subtype_Mark to
19528 Set_Result_Definition.
19529 (Make_Inequality_Operator): Change formal Subtype_Mark to
19530 Result_Definition in call to Make_Function_Specification.
19531 (Process_Formals): Create the new null-excluding itype if required.
19532 (New_Overloaded_Entity): For an entity overriding an interface primitive
19533 check if the entity also covers other abstract subprograms in the same
19534 scope. This is required to handle the general case, that is, overriding
19535 other interface primitives and overriding abstract subprograms inherited
19536 from some abstract ancestor type.
19537 (New_Overloaded_Entity): For an overriding entity that comes from
19538 source, note the operation that it overrides.
19539 (Check_Conformance, Type_Conformant): Addition of one new formal
19540 to skip controlling formals in the analysis. This is used to
19541 handle overloading of abstract interfaces.
19542 (Base_Types_Match): Add missing case for types imported from
19543 limited-with clauses
19544 (New_Overloaded_Entity): Add barrier to protect the use of
19545 the "alias" attribute.
19547 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19549 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
19550 verify that the procedure and the entry are mode conformant.
19551 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
19552 as a different operator, which is often a cut-and-paste error.
19554 2005-09-01 Javier Miranda <miranda@adacore.com>
19555 Ed Schonberg <schonberg@adacore.com>
19557 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
19558 used in controlling parameters exclude null because it is necessary to
19559 read the tag to dispatch, and null has no tag.
19560 (Override_Dispatching_Operation): If the previous operation is inherited
19561 from an interface, it becomes hidden and does not participate in later

19565 Ed Schonberg <schonberg@adacore.com>
19566 Gary Dismukes <dismukes@adacore.com>
19568 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
19569 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
19570 the expander will generate the corresponding run-time check to evaluate
19572 (Resolve_Call): Check for legal type of procedure name or prefix that
19573 appears as a trigger in a triggering alternative.
19574 (Valid_Conversion): If expression is ambiguous and the context involves
19575 an extension of System, remove System.Address interpretations.
19576 (Resolve_Qualified_Expression): Reject the case of a specific-type
19577 qualification applied to a class-wide argument. Enhance comment
19578 to explain checking of Original_Node.
19579 (Resolve_Type_Conversion): The location of the error message was not
19580 general enough to handle the general case and hence it has been removed.
19581 In addition, this patch improves the text of the message.
19582 (Resolve_Type_Conversion): Add missing support for access to interface
19584 (Resolve_Type_Conversion): If the target is a class-wide interface type,
19585 do not expand if the expression is the actual in a call, because proper
19586 expansion will take place when the call itself is expanded.
19587 (Resolve_Allocator): If the context is an unchecked conversion, the
19588 allocator inherits its storage pool, if any, from the target type of

19592 Javier Miranda <miranda@adacore.com>
19594 * sem_type.adb (Add_One_Interp): If a candidate operation is an
19595 inherited interface operation that has an implementation, use the
19596 implementation to avoid spurious ambiguities.
19597 (Interface_Present_In_Ancestor): In case of concurrent types we can't
19598 use the Corresponding_Record_Typ attribute to look for the interface
19599 because it is set by the expander (and hence it is not always
19600 available). For this reason we traverse the list of interfaces
19601 (available in the parent of the concurrent type).
19602 (Interface_Present_In_Ancestor): Handle entities from the limited view
19604 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19606 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
19607 from the list of required components.
19608 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
19609 primitive procedure of a limited interface with a controlling first
19611 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
19613 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
19614 capture if it is generated in the second operand of a short-circuit
19616 Do not capture values for variables with address clauses.
19617 (Is_Object_Reference): Treat a function call as an object reference only
19618 if its type is not Standard_Void_Type.
19620 2005-09-01 Ed Schonberg <schonberg@adacore.com>
19622 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied

20405 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
20406 longer protected objects. They have been replaced by lower-level
20407 suspension objects made up by a mutex and a condition variable (or
20408 their equivalent given a particular OS) plus some internal data to
20409 reflect the state of the suspension object.
20410 (Initialize, Finalize): Add this initialization procedure for
20411 Suspension_Object, which is a controlled type.

20438 object to True, releasing the task that was suspended, if any.
20439 (Suspend_Until_True): Add this procedure that blocks the calling task
20440 until the state of the object is True. Program_Error is raised if
20441 another task is already waiting on that suspension object.
20442 (Initialize): Add this procedure for initializing the suspension
20443 object. It initializes the mutex and the condition variable which are
20444 used for synchronization and queuing, and it sets the internal state
20446 (Finalize): Add this procedure for finalizing the suspension object,
20447 destroying the mutex and the condition variable.

20453 which provides a low-level abstraction (using operating system
20454 primitives) for Ada.Synchronous_Task_Control.
20455 This object is made up by a mutex (for ensuring mutual exclusion), a
20456 condition variable (for queuing threads until the condition is
20457 signaled), a Boolean (State) indicating whether the object is open,

20815 * i-cpp.ads, i-cpp.adb:
20816 This package has been left available for compatibility with previous

20861 (Analyze_Subprogram_Body): Undo the previous work.
20862 (Analyze_Procedure_Call): If the call has the form Object.Op, the
20863 analysis of the prefix ends up analyzing the call itself, after which

20866 subprogram_specification that returns true if some non
20867 class-wide interface subprogram is found
20868 (New_Overloaded_Entity): Modified to give support to abstract

20871 access to subprograms must be recursive.
20872 (Is_Unchecked_Conversion): Improve the test that recognizes
20873 instantiations of Unchecked_Conversion, and allows them in bodies that
20874 are to be inlined by the front-end. When the body comes from an

20897 object or component (that is, when Is_Local_Anonymous_Access is true).
20898 Prevent the special checks for conversions of access discriminants in
20899 the case where the discriminant belongs to a nonlimited type, since
20900 such discriminants have their accessibility level defined in the same
20901 way as a normal component of an anonymous access type.
20902 (Resolve_Allocator): When an allocator's designated type is a class-wide
20903 type, check that the accessibility level of type given in the
20904 allocator's expression or subtype indication is not statically deeper
20905 than the level of the allocator's access type.

20921 pragma Restrictions (No_Obsolescent_Features).
20922 (Check_Direct_Boolean_Operator): If the boolean operation has been
20923 constant-folded, there is nothing to check.
20924 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
20925 check on possible violation of restriction No_Direct_Boolean_Operators
20926 until after expansion of operands, to prevent spurious errors when

21137 Factor common code across the stream-oriented attribute circcuits into
21138 a new subprogram, Analyze_Stream_TSS_Definition. The new uniform

21206 * exp_aggr.adb (Aggr_Size_OK): An array with no components can always
21207 be expanded in place. The size computation does not require a
21208 subtraction, which would raise an exception on a compiler built with
21209 assertions when the upper bound is Integer'first.
21210 (Flatten): For an array of composite components, take into account the
21211 size of the components to determine whether it is safe to expand the

21226 Ed Schonberg <schonberg@adacore.com>
21228 * exp_dbug.ads, exp_dbug.adb (Get_Variant_Part): Fix the encoding of
21229 the "simple_choice" member in a variant record, in accordance with the
21230 description in the package spec: the information output for a constant
21231 should be "S number", not "SS number".
21232 (Get_Encoded_Name): Return at once if not generating code. Avoids name
21233 overflow problem when compiling with -gnatct, for ASIS/gnatmetrics.

21289 failure of our own connect(2) call.
21290 (Check_Selector): Improve documentation of the selector mechanism.
21291 (Broadcast_Inet_Addr): New constant.

21298 of the type is declared in a record (for determination of insertion
21300 (SO_Ref_From_Expr): Test whether Vtype denotes a partial or full view of

21320 unit as a consequence of parsing a limited-with clause. This is used
21321 to avoid the circularity check.

21324 (Analyze_Context): Limited-with clauses are now allowed
21325 in more compilation units.
21326 (Analyze_Subunit_Context, Check_Parent): Protect the frontend
21327 againts previously reported critical errors in context clauses
21328 (Install_Limited_Withed_Unit): Code cleanup plus static detection
21329 of two further errors: renamed subprograms and renamed packages

21347 Add information about generic parent for package and subprogram
21349 (Get_Type_Reference): For a subtype that is the renaming of an actual in
21350 an instantiation, use the first_subtype to ensure that we don't generate
21351 cross-reference information for internal types.

21931 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
21932 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
21933 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
21934 analyzed if expansion is disabled (which could otherwise cause spurious
21935 error messages if expansion has been disabled due to previous
21936 (unrelated) errors).
21938 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
21939 is disabled, the entity denoted by the argument is the access type
21940 itself, not an underlying record type, so there is no need to go back
21941 to the Corresponding_Remote_Type.
21943 2005-03-29 Gary Dismukes <dismukes@adacore.com>
21944 Robert Dewar <dewar@adacore.com>

21947 expand a call to an instance of
21948 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
21949 Constructor actual of the instance. A class-wide membership
21950 check is also generated, to ensure that the tag passed to the instance
21951 denotes a type in the class.
21952 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
21953 of Name_Generic_Dispatching_Constructor.
21955 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
21956 05 unit for AI-260-02).

21968 character type cases.
21969 (Analyze_Subprogram_Renaming): Add special handling for
21970 the case of renaming of stream attributes when the renaming denotes a
21971 generic formal subprogram association for an abstract formal subprogram.
21972 Check that the attribute is a primitive stream attribute (and not
21973 a class-wide stream attribute) and then rewrite the attribute name
21974 as the name of the appropriate compiler-generated stream primitive.
21976 2005-03-29 Robert Dewar <dewar@adacore.com>
21978 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

21985 * freeze.adb (Freeze_Record_Type): If the type of the component is an
21986 itype whose parent is controlled and not yet frozen, do not create a
21987 freeze node for the itype if expansion is disabled.
21989 2005-03-29 Vincent Celier <celier@adacore.com>
21991 * make.adb (Gnatmake): Don't fail if the main project file is declared
21992 as having no Ada sources. Do not display message "no sources to
21993 compile" in quiet output.
21995 2005-03-29 Doug Rupp <rupp@adacore.com>
21997 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

22008 missing TYPE Improve the error message generated when compiling a
22009 limited interface in Ada83 or Ada95 mode.
22011 2005-03-29 Robert Dewar <dewar@adacore.com>
22013 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
22014 rather than proceed ahead using a junk attribute name.
22016 2005-03-29 Vincent Celier <celier@adacore.com>
22018 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
22020 * prj-part.adb (Parse_Single_Project): Set the location of a project
22021 on its defining identifier, rather than on the reserved word "project".
22023 * prj-proc.adb (Expression): Adapt to the fact that default of external
22024 references may be string expressions, not always literal strings.
22025 (Recursive_Process): Set Display_Name equal to Name
22026 when Location is No_Location, that is when there is no actual file.
22027 Get the Display_Name of the project from the source, when it is not a
22029 (Process): Use the Display_Name in error messages
22031 * prj-strt.adb (External_Reference): Allow default to be string
22032 expressions, not only literal strings.
22034 2005-03-29 Vincent Celier <celier@adacore.com>
22036 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
22037 file and the reference symbol file to be the same file.

22041 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
22042 forbid conversion of a local access-to-subprogram type to a remote one.
22044 * sem_util.adb (Wrong_Type): For a record type that is the expanded
22045 equivalent type for a remote access-to-subprogram type, go back to the
22046 original RAS entity when displaying an error message, so the casing is
22047 the original source casing.
22049 2005-03-29 Robert Dewar <dewar@adacore.com>
22051 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
22054 2005-03-29 Ed Schonberg <schonberg@adacore.com>
22056 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
22057 subtype if code is being pre-analyzed, to prevent un-expanded
22058 references to protected formals, among others.
22059 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
22060 interpretation that can be a call, include the result of the call as a
22061 possible interpretation of the dereference.
22063 * sem_ch5.adb (Process_Bounds): Determine type of range by
22064 pre-analyzing a copy of the original range, and then analyze the range
22065 with the expected type.
22067 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
22068 with an overloaded prefix where not all interpretations yield an
22069 access to subprogram, do not rewrite node as a call.
22070 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
22071 the node as a call once the context identifies the interpretation of
22072 the prefix whose call yields the context type.
22073 (Valid_Conversion): For the case of a conversion between
22074 local access-to-subprogram types, check subtype conformance using
22075 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
22076 detailed error message.
22078 2005-03-29 Ed Schonberg <schonberg@adacore.com>
22080 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
22081 indicator, indicate that the formal can never be null.
22082 (Process_Formals): If a formal has a non_null indicator, insert the
22083 resulting subtype immediately before the enclosing subprogram decl,
22084 and not at the beginning of the corresponding declarative part, to
22085 prevent access before elaboration (Ada2005).
22087 2005-03-29 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
22090 * utils.c (finish_record_type): Use variable_size when setting sizes.

22650 left this interface a bit broken.
22652 * a-suteio.adb: Avoid unnecessary use of Get/Set_String
22654 * g-spipat.ads, g-spipat.adb: New interface for Get_String
22655 Minor reformatting (function specs)
22657 * g-spitbo.adb: New interface for Get_String
22659 * g-spitbo.ads: Minor reformatting
22661 * a-swunau.ads, a-swunau.adb: New interface for Get_Wide_String
22663 * a-szunau.ads, a-szunau.adb: New interface for Get_Wide_Wide_String
22665 2005-03-15 Javier Miranda <miranda@adacore.com>
22666 Robert Dewar <dewar@adacore.com>
22667 Thomas Quinot <quinot@adacore.com>
22668 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
22670 * atree.ads, atree.adb: Add support for Elist24 field
22672 * atree.h: Fix wrong definition of Field27
22673 Add support for Elist16 field
22674 Add support for Elist24 field
22676 * einfo.ads, einfo.adb (Abstract_Interfaces,
22677 Set_Abstract_Interfaces): New subprograms.
22678 (Abstract_Interface_Alias, Set_Abstract_Interface_Alias): New
22680 (Access_Disp_Table, Set_Access_Disp_Table): Modified to handle a list of
22681 entities rather than a single node.
22682 (Is_Interface, Set_Is_Interface): New subprogram
22683 (First_Tag_Component): New syntesized attribute
22684 (Next_Tag_Component): New synthesized attribute

22687 (Write_Field25_Name): Upgraded to write Abstract_Interface_Alias
22688 (Task_Body_Procedure): New subprogram to read this attribute.
22689 (Set_Task_Body_Procedure): New subprogram to set this attribute.
22690 (Has_Controlled_Component): Now applies to all entities.
22691 This is only a documentation change, since it always worked to apply
22692 this to other than composite types (yielding false), but now this is
22694 Update documentation on Must_Be_Byte_Aligned for new spec
22696 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
22697 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
22698 uses of the Access_Disp_Table attribute to reference the first dispatch
22699 table associated with a tagged type. As
22700 part of the implementation of abstract interface types,
22701 Access_Disp_Table has been redefined to contain a list of dispatch
22702 tables (rather than a single dispatch table).
22703 Similarly, upgrade all the references to Tag_Component by the
22704 new attribute First_Tag_Component.
22705 (Find_Inherited_TSS): Moved to exp_tss.
22706 Clean up test in Expand_N_Object_Declaration for cases
22707 where we need to do a separate assignment of the initial value.
22708 (Expand_N_Object_Declaration): If the expression in the
22709 declaration of a tagged type is an aggregate, no need to generate an
22710 additional tag assignment.
22711 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
22713 Bit packed array ops are only called if operands are known to be
22715 (Component_Equality): When returning an N_Raise_Program_Error statement,
22716 ensure that its Etype is set to Empty to avoid confusing GIGI (which
22717 expects that only expressions have a bona fide type).
22718 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
22719 determine the amount of data to be copied.
22721 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
22722 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
22723 INTERFACE_TYPE_DEFINITION ::=
22724 [limited | task | protected | synchronized] interface
22725 [AND interface_list]
22727 * par-ch3.adb (P_Type_Declaration): Modified to give support to
22729 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
22731 (P_Interface_Type_Definition): New subprogram that parses the new
22732 syntax rule of Ada 2005 interfaces
22733 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
22734 messages by the correct RENAMES (quotes removed).
22736 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
22737 attribute First_Tag_Component.
22739 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
22740 (Interface_List, Set_Interface_List): New subprograms.
22741 (Interface_Present, Set_Interface_Present): New subprograms.
22742 (Limited_Present, Set_Limited_Present): Available also in derived
22743 type definition nodes.
22744 (Protected_Present, Set_Protected_Present): Available also in
22745 record type definition and
22746 derived type definition nodes.
22747 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
22748 (Task_Present, Set_Task_Present): New subprogram.
22749 (Task_Body_Procedure): Removed.
22750 (Set_Task_Body_Procedure): Removed.
22751 These subprogram have been removed because the attribute
22752 Task_Body_Procedure has been moved to the corresponding task type
22753 or task subtype entity to leave a field free to store the list
22754 of interfaces implemented by a task (for AI-345)
22755 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
22756 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
22757 expression flag Do_Range_Check
22758 (Exception_Junk): Change to Flag7 to accomodate above change
22759 (Box_Present, Default_Name, Specification, Set_Box_Present,
22760 Set_Default_Name, Set_Specification): Expand the expression
22761 "X in N_Formal_Subprogram_Declaration" into the corresponding
22762 two comparisons. Required to use the csinfo tool.
22764 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
22765 "with string" given.
22767 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
22770 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
22773 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
22774 attribute Task_Body_Procedure rather than the old semantic field that
22775 was available in the task_type_declaration node.
22777 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
22778 interface type definitions.
22779 (P_Formal_Derived_Type_Definition): Modified to handle the list of
22782 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
22783 task type declaration.
22784 (P_Protected): Modified to handle the list of interfaces in a
22785 protected type declaration.
22787 2005-03-15 Doug Rupp <rupp@adacore.com>
22788 Vincent Celier <celier@adacore.com>
22790 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
22791 (Gen_Output_File_C): Likewise.
22792 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
22794 2005-03-15 Thomas Quinot <quinot@adacore.com>
22796 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
22797 is an N_Raise_Constraint_Error node, create a new copy of it without
22798 going through a call to Duplicate_Subexpr.
22800 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
22801 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
22802 Nicolas Setton <setton@adacore.com>
22803 Ed Schonberg <schonberg@adacore.com>
22809 * decl.c (gnat_to_gnu_field): Reject aliased components with a
22810 representation clause that prescribes a size not equal to the rounded
22811 size of their types.
22812 (gnat_to_gnu_entity, case E_Component): Always look at
22813 Original_Record_Component if Present and not the entity.
22814 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
22815 of tagged extension types by not making field for components that are
22817 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
22818 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
22819 expression to the type of the object when the object is constant.
22820 Reverse defer_debug_incomplete_list before traversing it, so that trees
22821 are processed in the order at which they were added to the list. This
22822 order is important when using the stabs debug format.
22823 If we are deferring the output of debug information, also defer this
22824 output for a function return type.
22825 When adding fields to a record, prevent emitting debug information
22826 for incomplete records, emit the information only when the record is
22828 (components_to_record): New parameter defer_debug.
22829 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
22830 (gnat_to_gnu_field_decl): New function.
22831 (substitution_list, annotate_rep): Call it.
22832 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
22833 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
22834 No longer update discriminants to not be a COMPONENT_REF.
22835 (copy_alias_set): Strip padding from input type; also handle
22836 unconstrained arrays properly.
22838 * gigi.h (write_record_type_debug_info): New function.
22839 Convert to use ANSI-style prototypes. Remove unused
22840 declarations for emit_stack_check, elab_all_gnat and
22841 set_second_error_entity.
22842 (gnat_to_gnu_field_decl): New decl.
22844 * utils.c (write_record_type_debug_info): New function.
22845 (finish_record_type): Delegate generation of debug information to
22846 write_record_type_debug_info.
22847 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
22848 (update_pointer_to): Fix pasto.
22849 (convert) <UNION_TYPE>: Accept slight type variations when
22850 converting to an unchecked union type.
22852 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
22853 replace the N_Freeze_Entity with a null statement.
22855 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
22856 within a constrained subcomponent of an enclosing record, place the
22857 freeze nodes in the scope stack entry for the enclosing record.
22858 (Undelay_Type): New Subprogram.
22859 (Set_Small_Size): Pass T, the type to modify; all callers changed.
22860 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
22861 within records; allow them to have freeze nodes if their base types
22864 * exp_util.adb (Remove_Side_Effects): Properly test for
22865 Expansion_Delayed and handle case when it's inside an
22866 N_Qualified_Expression.
22868 * sem_ch3.adb (Derived_Type_Declaration): New predicate
22869 Comes_From_Generic, to recognize accurately that the parent type in a
22870 derived type declaration can be traced back to a formal type, because
22871 it is one or is derived from one, or because its completion is derived
22873 (Constrain_Component_Type): If component comes from source and has no
22874 explicit constraint, no need to constrain in in a subtype of the
22876 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
22877 Minor change to propagate Is_Ada_2005 flag
22879 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
22880 Expansion_Delayed is False.
22881 (assoc_to_constructor): Ignore fields that have a
22882 Corresponding_Discriminant.
22883 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
22884 function returns "by target", dereference the target pointer using the
22885 type of the actual return value.
22886 <all>: Be prepared for a null gnu_result.
22887 (processed_inline_subprograms): Check flag_really_no_inline
22888 instead of flag_no_inline.
22889 (set_second_error_entity): Remove unused function.
22890 (gnat_to_gnu, case N_Selected_Component): Call
22891 gnat_to_gnu_field_decl.
22892 (assoc_to_constructor): Likewise.
22894 2005-03-15 Robert Dewar <dewar@adacore.com>
22895 Ed Schonberg <schonberg@adacore.com>
22896 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
22898 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
22899 Must_Be_Byte_Aligned for cases where we do not need to use a
22900 System.Pack_nn unit.
22902 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
22904 Needed now that we do some processing for IN parameters as well. This
22905 may well fix some unrelated errors.
22906 (Expand_Call): Handle case of unaligned objects (in particular those
22907 that come from packed arrays).
22908 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
22909 renamed entity is an inherited operation, re-expand the call using the
22910 original operation, which is the one to call.
22911 Detect attempt to inline parameterless recursive subprogram.
22912 (Represented_As_Scalar): Fix to work properly with private types
22913 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
22914 accurate estimate. Yields True in far fewer cases than before,
22915 improving the quality of code that depends on this test.
22917 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
22918 over both visible and private declarations to remove them from tree,
22919 and mark subprograms declared in package as eliminated, to prevent
22920 spurious use in subsequent compilation of generic units in the context.
22922 * exp_util.ads: Minor cleanup in variable names
22924 * sem_eval.ads, sem_eval.adb: Minor reformatting
22925 (Compile_Time_Known_Bounds): New function
22927 2005-03-15 Ed Schonberg <schonberg@adacore.com>
22929 * exp_ch7.adb (Convert_View): Use base types of underlying types when
22930 determining whether an unchecked conversion is needed for the argument
22931 of an initialization call.
22933 2005-03-15 Ed Schonberg <schonberg@adacore.com>
22935 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
22936 that appears in the instantiation rather than the internal subtype
22937 generated in the wrapper package, to avoid anomalies in gigi when the
22938 target is derived from a private type whose full view is an access type.
22940 2005-03-15 Robert Dewar <dewar@adacore.com>
22942 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
22944 Add documentation to replace the use of this flag
22945 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
22948 2005-03-15 Thomas Quinot <quinot@adacore.com>
22950 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
22951 here from exp_attr so it can be shared between exp_attr and exp_dist.
22952 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
22953 all TSS names, not a subset thereof, and the previous name introduced
22954 an unnecessarily confusion that a distinction might exist between
22955 "OK" TSS names and some "not OK" TSS names.
22957 2005-03-15 Doug Rupp <rupp@adacore.com>
22959 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
22962 2005-03-15 Pascal Obry <obry@adacore.com>
22963 Eric Botcazou <ebotcazou@adacore.com>
22967 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
22968 when IN_RTS. This is to work around a bootstrap path problem.
22970 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
22971 table and pass it to __gnat_install_SEH_handler().
22972 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
22974 * lang.opt: Fix specification of -fRTS=.
22976 2005-03-15 Doug Rupp <rupp@adacore.com>
22977 Bernard Banner <banner@adacore.com>
22978 Vincent Celier <celier@adacore.com>
22979 Arnaud Charlet <charlet@adacore.com>
22982 This change works fine when gnatlib is built from the gcc directory,
22983 but does not work when using the libada Makefile, since GCC_FOR_TARGET
22984 is not passed to ada/Makefile.in, so more work is needed by a
22985 Makefile/configure expert.
22987 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
22988 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
22989 Setup gnatlink switch -M for x86_64 linux, as it is already setup
22991 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
22992 Run ranlib on libgccprefix.a
22993 Define PREFIX_OBJS for Darwin, to build libgccprefix.
22994 (ADA_INCLUDE_SRCS): Split Ada packages.
22996 2005-03-15 Robert Dewar <dewar@adacore.com>
22998 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
23000 * impunit.adb: Add GNAT.UTF_32
23002 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
23004 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
23005 now uses GNAT.UTF_32).
23007 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
23008 capabilities for categorizing characters using Unicode categories
23010 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23012 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
23013 instantiation that has been rewritten as a package body, retrieve spec
23014 to generate proper name for implicit_with_clause.
23015 (Install_Parents): Recognize a parent that is an instantiation but has
23016 been rewritten as a package declaration during analysis.
23018 2005-03-15 Javier Miranda <miranda@adacore.com>
23019 Ed Schonberg <schonberg@adacore.com>
23021 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
23022 parameter reported some error we immediately return. This improves the
23023 behaviour of the frontend in case of errors.
23024 (Install_Parent, Remove_Parent): Introduce new flag
23025 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
23026 ancestor of a generic child unit, when the child is being instantiated.
23027 (Inline_Instance_Body): If we are compiling the private
23028 part or the body of a child unit, restore the proper visibility of the
23029 parents after compiling the instance body.
23031 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23032 Javier Miranda <miranda@adacore.com>
23035 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
23036 of a private type, in which case it is underlying_type that denotes
23037 the proper task. Also modified to use the new entity attribute
23038 that is directly available in the task type and task subtype entities
23039 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
23040 arrays when other dimensions than the first are constrained by
23041 discriminants of an enclosing record.
23042 (Insert_Explicit_Dereference): If the prefix is an indexed component or
23043 a combination of indexed and selected components, find ultimate entity
23044 and generate the appropriate reference for it, to suppress spurious
23046 (Note_Possible_Modification): If an entity name has no entity, return.
23047 (Is_Variable): A function call never denotes a variable.
23048 (Requires_Transient_Scope): For record types, recurse only on
23049 components, not on internal subtypes that may have been generated for
23050 constrained components.
23052 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23054 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
23055 Eliminated as candidates for resolution. Both efficient, and avoids
23056 anomalies with operators declared in deleted code.
23057 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
23058 expansion is disabled (as when compiling a generic) to prevent spurious
23059 warnings on prefixes of selected components.
23061 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23063 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
23064 attached to a list before checking whether it appears in the private
23065 declarations of the current package.
23066 (Make_Inequality_Operator): Insert declaration in proper declarative
23067 list rather than just setting the Parent field, so that
23068 Is_Private_Declaration can handle it properly.
23070 2005-03-15 Ed Schonberg <schonberg@adacore.com>
23072 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
23073 a renaming a body, check that the renamed subprogram in not intrinsic.
23074 (Find_Direct_Name): If several use_visible entities hide
23075 each other, and the context is a predefined file compiled through
23076 rtsfind, keep only the entity that comes from a predefined file.
23078 2005-03-15 Geert Bosch <bosch@adacore.com>
23080 * s-fatgen.adb (Valid): Extend special exceptions to account for long
23081 long float padding to also cover AMD64 and IA64.
23083 2005-03-15 Gary Dismukes <dismukes@adacore.com>
23085 * s-imgwch.adb: Add with and use of Interfaces.
23086 (Img_Wide_Character): Change type of Val to Unsigned_16.
23087 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
23089 2005-03-15 Matthew Gingell <gingell@adacore.com>
23091 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
23093 2005-03-15 Robert Dewar <dewar@adacore.com>
23095 * usage.adb: Add missing lines for -gnat95 and -gnat05 switches
23097 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
23099 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
23101 2005-03-15 Robert Dewar <dewar@adacore.com>
23103 * s-bitops.adb, s-bitops.ads,
23104 s-taprop-os2.adb, s-intman-vms.ads, s-intman-vxworks.ads,
23105 s-taprop-vxworks.adb, a-caldel.ads, a-calend.adb, a-tasatt.adb,

23114 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
23116 * utils2.c (build_binary_op): Fix typo.

23540 describing the new layout.
23541 (Dispatch_Table): The expander computes the actual array size, allocates
23542 the Dispatch_Table record accordingly, and generates code that displaces
23543 the base of the record after the Typeinfo_Ptr component. The access to
23544 these components is done by means of local functions.

23561 dispatching, setting the controlling status of the formal parameters
23562 and result, and issuing an error if there is no controlling type for
23563 the formal subprogram.
23564 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
23565 which is an unclean use of that field, we set the new field
23566 Corresponding_Formal_Spec to make the formal subprogram available to

23579 subprogram only if inner one comes from source.
23580 (Analyze_Function_Call): If the call is given in object notation, the

23582 argument list. After analyzing the name, if the call has been rewritten
23583 and the result type is set, no further analysis is needed.
23584 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
23585 mark in function specification, in a context where the formals are
23586 visible and hide outer homographs.
23588 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
23589 as the tagged type for the cases of abstract formal subprograms and
23590 renamings of those. Clean up spec comments.
23591 (Check_Dispatching_Context): Add error message to indicate "abstract
23592 procedure", covering the case of a call to a formal abstract procedure
23593 that has statically tagged operands.
23594 (Check_Dispatching_Call): Check for the case of an actual given by
23595 a tag-indeterminate function call whose type is an ancestor of the
23596 containing call's associated tagged type. This situation can occur
23597 for inherited primitives with function defaults. In this case we

23675 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
23679 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
23680 on the field if Pragma Component_Alignment (Storage_Unit).
23681 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
23682 side-effects as if it were a constant; also make SAVE_EXPR to protect

23700 2005-02-09 Ed Schonberg <schonberg@adacore.com>
23702 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
23703 component of an array of arrays in an assignment context, and the
23704 aggregate has component associations that require sliding on
23705 assignment, force reanalysis of the aggregate to generate a temporary
23706 before the assignment.
23707 (Must_Slide): Make global to the package, for use in Gen_Assign.
23709 2005-02-09 Ed Schonberg <schonberg@adacore.com>
23711 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
23712 unchecked union with no inferable discriminants, return a

23725 Arnaud Charlet <charlet@adacore.com>
23727 * init.c (__gnat_initialize): Add a new parameter eh which contains the
23728 address of the exception registration. The Win32 version of this
23729 routine calls __gnat_install_SEH_handler() to initialize the SEH
23730 (Structured Exception Handling) handler.
23731 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
23732 SEH (Structured Exception Handling) now.
23733 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
23734 (__gnat_initialize for ppc-vxworks): Adjust comments and the
23735 preprocessor condition protecting the call to the extra eh setup
23736 subprogram, which is only available for the ppc target.
23737 (__gnat_clear_exception_count): replaced reference to
23738 variable taskIdCurrent by call to taskIdSelf(), cleaner.

23743 (GNATBIND_OBJS): Idem.
23745 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
23746 routine takes a new parameter (a pointer to the exception registration
23747 for the SEH (Structured Exception Handling) support.
23749 * raise.h: (__gnat_install_SEH_handler): New prototype.
23750 Update copyright notice.
23752 * s-tassta.adb (Task_Wrapper): Declare the exception registration

23782 2005-02-09 Vincent Celier <celier@adacore.com>
23784 * prj-makr.adb (Process_Directory): Put file name in canonical case
23785 before matching against the patterns.
23786 If gnatname has been invoked as <prefix>-gnatname
23787 then invoke the compiler as <prefix>-gcc, not just "gcc".
23789 2005-02-09 Ed Schonberg <schonberg@adacore.com>
23791 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
23792 with expansion disabled. The actual subtype is needed among other
23793 places when the selected component appears in the context of a loop
23794 bound, and denotes a packed array.
23795 (Operator_Check): Always use the first subtype in the
23796 error message, to avoid the appearance of internal base types.
23797 (Transform_Object_Operation): Copy each actual in full
23798 to the parameter associations of the constructed call, rather than
23799 using the shallow copy mechanism of New_Copy_List. This ensures that
23800 the chaining of named associations is done properly.
23801 (Complete_Object_Operation): Rewrite node, rather than
23802 replacing it, so that we can trace back to the original selected
23805 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
23806 and calls that use object notation, if the called function is not
23807 declared in a withed unit, place the elaboration constraint on the
23808 unit in the context that makes the function accessible.
23809 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
23810 imposes an elaboration constraint between two packages.
23812 2005-02-09 Ed Schonberg <schonberg@adacore.com>
23814 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
23815 views of a private type after handling its private dependents, to
23816 maintain proper stack discipline between entry and exit from the

23842 we now use by default.
23844 * xsnames.adb: Adjust end of file test to look for five space followed
23845 by '#' instead of six spaces. The format of xsnames.adb was modified
23846 in the last update.
23848 * a-numeri.ads: Add reference to AI-388 for greek letter pi
23851 * clean.adb: Minor reformatting.
23853 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,

23857 * csets.adb: Eliminate obsolete comment
23859 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
23862 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
23864 2005-02-09 Sergey Rybin <rybin@adacore.com>
23866 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
23867 the difference between compact and incompact layout and add the record
23868 representation clause to the example illustrating different layouts.
23869 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
23870 component clauses").
23872 2005-02-09 Florian Villoing <villoing@adacore.com>
23874 * gnat_ugn.texi: Fix typos.
23875 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

23922 * exp_util.ads: Minor correction in comment.
23924 2005-02-09 Arnaud Charlet <charlet@adacore.com>
23926 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,

24585 value_factor_p instead of a raw binop construction to check for the
24586 position's alignment.
24588 2004-12-07 Geert Bosch <bosch@adacore.com>

24593 Ed Schonberg <schonberg@adacore.com>
24595 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
24596 with an implicit dereference as its prefix, use
24597 Insert_Explicit_Dereference instead of merely rewriting the prefix into
24598 an explicit dereference. This ensures that a reference to the original
24599 prefix is generated, if appropriate.
24601 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
24602 dereference is rewritten to an explicit one, generate a reference to
24603 the entity denoted by its prefix using the original prefix node, so
24604 the dereference can be properly recorded as a read of the denoted
24605 access value, if appropriate.
24607 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
24608 emitting 'assigned but never read' warning on a variable on the basis
24609 that it has an access type.
24610 (Check_References): Emit unreferenced warning when the scope is a

24619 * exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
24620 leaving call unchanged.
24621 This deals with the case where the pragma Import specified
24622 an external name, to be handled by the back end.
24624 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
24625 subprogram which is Imported with convention Intrinsic if an
24626 External_Name argument is specified.
24627 (Process_Import_Or_Interface): Properly diagnose link name argument.
24628 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
24629 with Sem_Ch6.Cannot_Inline.
24630 (Process_Inline): Provide separate warning for inapplicable inline
24632 (Cannot_Inline): Reject subprograms that have an at_end handler, so that
24633 treatment is uniform on different targets.
24635 2004-12-07 Ed Schonberg <schonberg@adacore.com>
24637 * exp_ch7.adb (Expand_Cleanup_Actions): If statement sequence of
24638 construct is rewritten, preserve end label to permit source navigation.

24642 * exp_dist.adb (Specific_Build_General_Calling_Stubs,
24643 Specific_Build_Stub_Target): New subprograms.
24644 (Build_Subprogram_Calling_Stubs): Make this procedure independent from
24645 the PCS implementation used, using the above PCS-customized subprograms.
24646 Minor reformatting.
24647 (PolyORB_Support.Helpers): New subunit containing supporting subprograms
24648 for generation of DSA code targeted to the PolyORB PCS.
24649 (Add_Stub_Type): Rewrite to isolate the parts that are specific to one
24650 implementation of the partition communication subsystem in ancillary
24652 (Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,
24653 PolyORB_Support.Build_Stub_Type): New subrograms containing the
24654 PCS-specific part of Add_Stub_Type.
24655 (Insert_Partition_Check): Use runtime library function to perform
24658 * rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref
24659 (RE_Same_Partition): New entity, from s-parint.
24661 * s-parint.ads, s-parint.adb (Same_Partition): New subprogram.

24678 2004-12-07 Ed Schonberg <schonberg@adacore.com>
24681 (Generate_Reference): Handle properly a reference to an entry formal,
24682 when an accept statement has a pragma Unreferenced for it.
24684 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
24685 and the Has_Pragma_Unreferenced flag for each formal before analyzing
24686 the body, to ensure that warnings are properly emitted for each accept
24687 statement of a given task entry.
24689 2004-12-07 Vasiliy Fofanov <fofanov@adacore.com>
24691 * Makefile.in: Add support for foreign threads on VMS.

24709 (Remove_Next_Debug): Same fix
24711 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
24712 maintain back pointers now, though we did not used to, and comments
24714 (Prepend): Remove pragma Inline.
24715 (Remove_Next): Same cleanup
24717 2004-12-07 Thomas Quinot <quinot@adacore.com>
24719 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
24720 used to record an implicit dereference as a read operation on its
24721 prefix when operating under -gnatc. Necessary to avoid spurious
24722 'variable assigned but never read' warnings in that mode.
24723 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
24724 is a non-overloaded implicit dereference, call the above subprogram to
24725 ensure proper recording of references.
24727 2004-12-07 Gary Dismukes <dismukes@adacore.com>
24729 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
24730 to be resolved later as part of Analyze_Iteration_Scheme's call to
24733 2004-12-07 Ed Schonberg <schonberg@adacore.com>
24735 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

24775 Add gnatmetric section
24777 2004-12-07 Vincent Celier <celier@adacore.com>
24779 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
24780 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
24781 and -eit to -ept. Added qualifier
24782 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
24784 2004-11-27 Andreas Schwab <schwab@suse.de>
24786 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
24788 2004-11-25 Arnaud Charlet <charlet@adacore.com>
24790 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
24791 internal implementation unit GNAT.Sockets.Thin,
24792 as their usage for sockets is non-portable (using the read and write
24793 functions from the system runtime library is fine on UNIX but won't
24794 work under Windows).
24796 * mingw32.h: Update copyright notice.
24798 2004-11-25 Arnaud Charlet <charlet@adacore.com>
24800 * ada-tree.h: Minor reformatting of previous change to avoid lines
24801 longer than 79 characters.

24841 2004-11-18 Olivier Hainque <hainque@adacore.com>
24843 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
24844 address of which may be used to represent "others" and "all others"
24845 choices in exception tables, instead of the current harcoded
24846 (void *)0 and (void *)1.
24847 (Setup_Exception): Do nothing in the GNAT SJLJ case.
24849 * gigi.h (others_decl, all_others_decl): New decls representing the
24850 new Others_Value and All_Others_Value objects.
24851 (struct attrib): Rename "arg" component as "args", since GCC expects a
24852 list of arguments in there.
24854 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
24855 corresponding objects exported by a-exexpr, instead of hardcoded dummy
24858 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
24859 others_decl and all_others_decl instead of hardcoded dummy addresses
24860 to represent "others" and "all others" choices, which is cleaner and
24861 more flexible with respect to the possible eh pointer encoding policies.
24863 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
24864 (process_attributes): Account for the naming change of the "args"
24865 attribute list entry component.
24867 * decl.c (build_attr_list): Rename into prepend_attributes to allow
24868 cumulating attributes for different entities into a single list.
24869 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
24870 attributes for the current entity and propagate first subtype
24871 attributes to other subtypes.
24872 <E_Procedure>: Attribute arguments are attr->args and not
24873 attr->arg any more.
24874 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
24875 argument provided, as this is what GCC expects. Use NULL_TREE instead
24878 2004-11-18 Robert Dewar <dewar@adacore.com>
24880 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
24881 Minor reformatting througout (including new function specs)
24882 Add ??? comments asking for clarification.
24884 2004-11-18 Thomas Quinot <quinot@adacore.com>

24892 procedures factors the common processing for building an RPC receiver
24893 for an RCI package or an RACW type.

24908 (Add_RAS_Dereference_TSS): Add comments.
24909 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
24910 is not referenced yet because it will be used by the PolyORB DSA
24912 (Insert_Partition_Check): Remove fossile code.
24913 (First_RCI_Subprogram_Id): Document this constant.
24914 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
24916 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
24917 replaced with calls to Get_Library_Unit_Name_String. Previously there
24918 were several instances of the same code in different locations in the
24919 compiler; this checkin completes the replacement of all of these
24920 instances with calls to a common subprogram.
24921 Minor reformatting.
24923 * sem_dist.adb: Remove comment noting that RPC receiver generation
24924 should be disabled for RACWs that implement RASs.

24949 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
24950 (Expand_Pragma_Psect_Object): New procedure
24951 These procedures contain the revised and cleaned up processing for
24952 these two pragmas. This processing was formerly in Sem_Prag, but
24953 is more appropriately moved here. The cleanup involves making sure
24954 that the pragmas are properly attached to the tree, and that no
24955 nodes are improperly shared.
24957 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
24958 pragmas to Exp_Prag, which is more appropriate.
24959 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
24960 check for duplicates Remove use of Is_Psected flag, no longer needed.
24961 Use new Make_String_Literal function with string.
24963 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
24964 that are functions return universal values, that have to be converted
24965 to the context type.
24966 Use new Make_String_Literal function with string.
24967 (Get_Stream_Convert_Pragma): New function, replaces the use of
24968 Get_Rep_Pragma, which had to be kludged to work in this case.
24970 * freeze.adb: Use new Has_Rep_Pragma function
24972 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
24973 function with string.
24974 Use new Has_Rep_Pragma function.

24998 Robert Dewar <dewar@adacore.com>
25000 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
25001 discriminant of a constrained subtype, analyze the copy of the
25002 corresponding constraint, because in some cases it may be only
25003 partially analyzed.
25004 Removes long-lived ??? comments.
25006 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
25007 handled controlled or secondary-stack expressions within the
25008 iteration_scheme of a loop.
25010 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
25011 bounds that may contain functions calls, to prevent memory leaks when
25012 the bound contains a call to a function that uses the secondary stack.
25013 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
25014 generate temporaries for loop bounds that might contain function calls
25015 that require secondary stack and/or finalization actions.
25017 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
25018 selected component and the selector is overloadable (not just a
25019 function) treat as function call, Analyze_Call will disambiguate if
25021 (Analyze_Selected_Component): Do not generate an actual subtype for the
25022 selected component if expansion is disabled. The actual subtype is only
25023 needed for constraint checks.
25024 (Analyze_Allocator): If restriction No_Streams is set, then do
25025 not permit objects to be declared of a stream type, or of a
25026 composite type containing a stream.
25028 * restrict.ads: Remove the a-stream entry from Unit_Array, since
25029 No_Streams no longer prohibits with'ing this package.
25031 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
25032 discriminants, but the parent base has unknown discriminants, there is
25033 no discriminant constraint to inherit. Such a discrepancy can arise
25034 when the actual for a formal type with unknown discriminants is a
25035 similar private type whose full view has discriminants.
25036 (Analyze_Object_Declaration): If restriction No_Streams is set, then
25037 do not permit objects to be declared of a stream type, or of a
25038 composite type containing a stream.
25040 2004-11-18 Ed Schonberg <schonberg@adacore.com>
25042 * exp_dbug.ads: Update documentation to reflect simpler encoding for
25043 protected operations.
25045 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
25046 generated name, it complicates decoding in gdb and hinders debugging
25047 of protected operations.

25049 flag for the protected entry barrier function.
25050 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info

25065 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
25066 type of the object with the packed array type, set the Analyzed flag
25067 on the object if it is an entity or simple indexed component, to avoid
25068 spurious type errors.

25090 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
25091 for Detect_Blocking which is redundant with the check done within the
25092 procedure Protected_Single_Entry_Call.
25093 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
25094 Detect_Blocking which is redundant with the check done within the
25095 procedure Protected_Single_Entry_Call.
25097 2004-11-18 Vincent Celier <celier@adacore.com>
25099 * makegpr.adb (Compile): Put the compiling switches (in package
25100 Compiler and on the command line) immediately after "-c", instead of
25101 at the end of the command line invocation of the compiler, when
25102 compiling a non-Ada file.
25103 (Build_Global_Archive): When there is no need to rebuild the archive,
25104 set Global_Archive_Exists, so that the archive is passed to the linker
25107 2004-11-18 Robert Dewar <dewar@adacore.com>
25108 Sergey Rybin <rybin@adacore.com>
25111 Remove extra paren check from list of checks for redundant constructs
25112 Add documentation of new -gnatyx style check (check extra parens)
25113 Remove paragraph about gnatelim debug options.
25115 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
25116 objects rather than forbidding dependencies on the package Ada.Streams.
25118 * sinfo.ads: Add ??? note that we should document pragmas passed to
25121 * g-expect.ads: Fix a few typos in the comments.
25123 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
25125 * misc.c (gnat_handle_option): Use %< and %> for quoting in
25128 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
25130 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
25132 2004-11-07 Andreas Schwab <schwab@suse.de>
25134 * Makefile.in (install-gnatlib): Remove spurious hyphen.
25136 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
25139 * Makefile.in (darwin): Set soext to .dylib.
25141 2004-10-26 Vincent Celier <celier@gnat.com>
25142 Thomas Quinot <quinot@act-europe.fr>
25144 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
25145 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
25146 there is no use of GNAT.Sockets.Constants.
25147 Remove remaining pragma Import for C_Write
25148 Remove C_Read and C_Write from internal implementation unit
25149 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
25150 the read and write functions from the system runtime library is fine
25151 on UNIX but won't work under Windows).
25153 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
25154 (Check_Selector): Use C_Recv instead of C_Read.
25155 Selectors are the GNAT.Sockets abstraction to perform a select()
25156 call on a set of descriptors. To allow abortion of an ongoing
25157 select operation, some data is written to a dedicated socket that
25158 is always monitored.
25159 Under Windows, the write and read library functions cannot operate
25160 on sockets, so we need to use send and recv instead, which is portable
25161 across all supported platforms.
25163 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
25164 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
25165 (using the read and write functions from the system runtime library is
25166 fine on UNIX but won't work under Windows).
25168 2004-10-26 Nicolas Setton <setton@act-europe.fr>
25170 * mlib-tgt-darwin.adb: New file.
25172 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
25173 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
25174 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
25175 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
25178 * Makefile.in: Add support for building shared libraries under Darwin.
25179 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
25180 the low level EH init subprogram to be called from __gnat_initialize.
25182 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
25183 indicates which options to pass to the archive indexer.
25185 * mlib-utl.adb: Add support for calling ranlib with additional
25186 options. This is needed for instance under Mac OS X.
25187 (Ranlib_Options): New global variable, used to store the potential
25188 options to pass to ranlib.
25189 (Ar): Use Ranlib_Options when spawning ranlib.
25190 (Initialize): Set the value of ranlib option.
25192 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
25194 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
25195 instead of 8K, to reflect the real potential needs for stack-checking
25198 2004-10-26 Pascal Obry <obry@gnat.com>
25200 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
25202 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
25203 Windows only the initial thread stack size can be set so it is good to
25204 start we a low stack size.
25205 The OS will adjust the size as needed.
25207 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
25208 Nicolas Setton <setton@act-europe.fr>
25210 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
25211 "__unix__" instead of "unix".
25212 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
25213 sections were just mistakenly ignored. The former is
25214 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
25215 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
25216 of hpux. This prevents an unwanted definition of the symbol
25217 convert_addresses in adaint.o.
25219 2004-10-26 Gary Dismukes <dismukes@gnat.com>
25221 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
25222 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
25224 2004-10-26 Cyrille Comar <comar@act-europe.fr>
25226 * a-filico.ads, a-filico.adb: fix incorrect header.
25228 2004-10-26 Javier Miranda <miranda@gnat.com>
25230 * a-ststio.ads: Fix typo in identifier
25232 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25234 * sem_ch4.adb: Minor reformatting.
25236 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25238 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
25239 enabled, check the result of unary and binary operations when the
25240 expression is the right-hand side of an assignment.
25242 2004-10-26 Vincent Celier <celier@gnat.com>
25244 * clean.adb (Delete): Do not output warnings when in quiet output and
25245 not in verbose mode.
25246 (Force_Deletions): New Boolean flag, defaulted to False
25247 (Delete): Only delete a file if it is writable, and when
25248 Force_Deletions is True.
25249 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
25250 (Usage): Line for new switch -f
25251 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
25254 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
25256 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
25257 JM type only if its size matches that of the wrapper. When a size is
25258 prescribed and the field is not aliased, remove the wrapper of a JM
25259 type only if the size is not greater than that of the packed array.
25260 (gnat_to_gnu_entity): Change the extension of packed array wrappers
25263 2004-10-26 Geert Bosch <bosch@gnat.com>
25265 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
25266 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
25267 (Pred): Implement in terms of Succ.
25269 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25271 * exp_aggr.adb (Safe_Component): An aggregate component that is an
25272 unchecked conversion is safe for in-place use if the expression of the
25273 conversion is safe.
25274 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
25275 be expandable in place even if the aggregate does not come from source.
25276 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
25277 designated object of an allocator in place, rather than building it
25278 first on the stack. The previous scheme forces a full copy of the array,
25279 and may be altogether unsusable if the size of the array is too large
25280 for stack allocation.
25282 2004-10-26 Robert Dewar <dewar@gnat.com>
25284 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
25285 compares if the component is atomic.
25287 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
25288 array assignment if the component type is atomic.
25290 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25291 Eric Botcazou <ebotcazou@act-europe.fr>
25293 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
25294 is aliased and is a by_reference type, do not pass by copy.
25295 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
25296 detect whether the call is in the right side of an assignment or
25297 the expression of an object declaration. Recurse on component
25298 association within aggregates.
25299 Call it in the condition that determines whether the temporary is
25300 necessary for correct stack-checking.
25302 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25304 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
25305 RACW_Type, used in the PolyORB version.
25306 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
25307 version and the GARLIC version.
25309 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
25310 Rename RCI_Info to RCI_Locator for better consistency between the
25311 GARLIC and PolyORB versions of the distributed systems annex.
25312 (DSA_Implementation_Name): This enumeration lists the possible
25313 implementations of the Partition Communication Subsystem for the
25314 Distributed Systems Annex (DSA). The three available implementations
25315 are the dummy stub implementation (No_DSA), and two versions based on
25316 two different distribution runtime libraries: GARLIC and PolyORB. Both
25317 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
25319 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
25322 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
25323 between the GARLIC and PolyORB versions of the distributed systems
25325 Remove RE_Unbounded_Reclaim_Pool since it is unused.
25327 2004-10-26 Gary Dismukes <dismukes@gnat.com>
25329 * gnat1drv.adb: Suppress calling the back end when
25330 Frontend_Layout_On_Target is true.
25332 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25334 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
25335 Set_Read_Only): New subprograms.
25336 These new routines allow the user to set or unset the Owner execute
25337 and Owner write permission flags on a file.
25339 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
25340 GNAT.OS_Lib.Set_Executable instead of rolling our own.
25342 2004-10-26 Matthew Gingell <gingell@gnat.com>
25344 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
25346 2004-10-26 Pascal Obry <obry@gnat.com>
25348 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
25349 memory before the faulting page we properly test the process read
25350 access for this address using appropriate Win32 routine.
25351 (HPUX sections): guard with "__hpux__" instead of "hpux".
25353 2004-10-26 Robert Dewar <dewar@gnat.com>
25355 * lib-xref.adb (Generate_Reference): Don't complain about reference to
25356 entry parameter if pragma Unreferenced set, since we do not properly
25357 handle the case of multiple parameters.
25359 2004-10-26 Vincent Celier <celier@gnat.com>
25361 * prj-env.adb: (Contains_ALI_Files): New Boolean function
25362 (Ada_Objects_Path.Add): For a library project, add to the object path
25363 the library directory only if there is no object directory or if the
25364 library directory contains ALI files.
25365 (Set_Ada_Paths.Add.Recursive_Add): Ditto
25367 2004-10-26 Vincent Celier <celier@gnat.com>
25369 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
25370 extension of library projects.
25372 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
25373 path defaults to ".:<prefix>/lib/gnat".
25374 (Parse): For an extending all project, allow direct import of a project
25375 that is virtually extended.
25377 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
25378 the specified name is directly imported, return its ID. Otherwise, if
25379 an extension of this project is imported, return the ID of the
25382 2004-10-26 Robert Dewar <dewar@gnat.com>
25384 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
25385 (Sub3): New procedure, used by Scaled_Divide
25386 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
25387 correct more than one instance of failure to propagate carries
25389 (Double_Divide): Handle overflow case of largest negative number
25390 divided by minus one.
25392 * s-arit64.ads (Double_Divide): Document that overflow can occur in
25393 the case of a quotient value out of range.
25396 2004-10-26 Robert Dewar <dewar@gnat.com>
25398 * s-bitops.adb (Bit_Eq): Remove redundant check.
25400 * s-bitops.ads: Minor comment updates
25401 Change some occurrences of Address to System.Address
25403 * s-carsi8.ads: Fix minor cut-and-paste error in comments
25405 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25407 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
25408 accessibility check to prefix that is a protected operation.
25410 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25412 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
25413 empty, post message on stub.
25415 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25416 Javier Miranda <miranda@gnat.com>
25418 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
25419 current instance appears within a unit that is directly in the context
25421 Used to determine whether the body of the instance should be analyzed
25422 immediately after its spec, to make its subprogram bodies available
25423 for front-end inlining.
25424 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
25425 constraint is not allowed on the component type (AARM 12.5.3(3))
25427 2004-10-26 Cyrille Comar <comar@act-europe.fr>
25429 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
25430 'Storage_Pool): enhance, document & limit detection of non-sharable
25433 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
25435 * s-pooglo.ads: Add more documentation now that this pool is properly
25438 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25440 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
25441 or protected type with discriminants, do not constrain the
25442 corresponding record type if the subtype declaration has no
25443 discriminant constraints. This can be the case in source code, or in
25444 the subtype declaration created to rename an actual type within an
25447 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25449 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
25450 different kind of stub (possibly wrong name for file), do not check
25452 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
25453 includes call to some function that returns an unconstrained type, do
25456 2004-10-26 Ed Schonberg <schonberg@gnat.com>
25458 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
25459 appear in the code for the main unit. Dependencies among units in the
25460 context of the main unit are established when those other units are
25461 compiled. Otherwise spurious elaboration constraints can generate
25462 incorrect elaboration circularities.
25464 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
25465 Ed Schonberg <schonberg@gnat.com>
25467 * sem_util.adb (Is_Aliased_View): Defend against the case where this
25468 subprogram is called with a parameter that is not an object name. This
25469 situation arises for some cases of illegal code, which is diagnosed
25470 later, and in this case it is wrong to call Is_Aliased, as that might
25471 cause a compiler crash.
25472 (Explain_Limited_Type): Refine previous fix to include
25473 inherited components of derived types, to provide complete information.
25475 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
25476 is the prival for a protected object.
25477 It is necessary to mark this entity as a variable, in addition to
25478 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
25479 modified to avoid checking the Aliased flag on entities that are not
25480 objects. (Checking that flag for non-objects is erroneous and could
25481 lead to a compiler crash).
25483 2004-10-26 Robert Dewar <dewar@gnat.com>
25485 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
25486 X_Frac = 0.5, then we know that the number X must be positive.
25487 (Succ): Remove the same redundant test, and also fix the primary test
25488 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
25490 (Decompose): Add fuller comments to spec
25492 2004-10-26 Pascal Obry <obry@gnat.com>
25494 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
25495 validity (process must have read access). Set to 0 in all other cases.
25496 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
25497 violation on Win32.
25498 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
25499 segmentation violation.
25501 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
25503 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
25504 whose type is a constructed subtype of an aliased object with an
25505 unconstrained nominal subtype, convert the actual to the constructed
25506 subtype before taking its address.
25508 2004-10-26 Vincent Celier <celier@gnat.com>
25510 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
25511 (Is_Path_Name_Case_Sensitive): New function
25513 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
25514 (Base_Name, Simple_Name, Current_Directory, Compose,
25515 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
25518 2004-10-26 Cyrille Comar <comar@act-europe.fr>
25519 Vasiliy Fofanov <fofanov@act-europe.fr>
25520 Vincent Celier <celier@gnat.com>
25522 * gnat_ugn.texi: Generalize "finding memory problems" section into a
25523 "memory management issues" section and document some of the useful
25524 memory pools provided as part of the GNAT library.
25525 Remove "virtual" from declaration of A::method2 in
25526 the simple example of Ada/C++ mixed system.
25527 Library Projects may be virtually extended: their virtual extensions
25528 are not Library Projects.
25529 Added section on extending project hierarchies.
25531 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
25533 * adaint.c (__gnat_get_libraries_from_registry): Cast value
25535 (__gnat_portable_spawn): Remove const.
25537 * mingw32.h (MAXPATHLEN): Check for previous definition.
25539 2004-10-17 Matthias Klose <doko@debian.org>
25541 * gnatvsn.ads: Set gnat library version to 4.0.
25543 2004-10-05 Vincent Celier <celier@gnat.com>
25545 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
25547 2004-10-04 Laurent Guerby <laurent@guerby.net>
25550 * Makefile.in: Define and use RANLIB_FLAGS.
25552 2004-10-04 Pascal Obry <obry@gnat.com>
25554 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
25555 other x86 platforms).
25557 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
25559 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
25560 in general and triggers stack alignment adjustment for thread entry
25561 points on targets where this is necessary.
25563 2004-10-04 Bernard Banner <banner@gnat.com>
25566 * Makefile.in: Add section for powerpc linux
25567 Add variant i-vxwork-x86.ads
25569 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
25571 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
25573 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
25574 table registration calls when need be. Ensures no reference to the crt
25575 ctors symbol are issued in the SJLJ case, which avoids possible
25576 undefined symbol errors in the case of modules to be statically linked
25579 2004-10-04 Javier Miranda <miranda@gnat.com>
25581 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
25582 in-line the code corresponding to subprogram Analyze_Actuals. In
25583 addition, analyze the actuals only in case of subprogram call.
25585 2004-10-04 Ed Falis <falis@gnat.com>
25587 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
25589 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
25591 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
25592 in the documentation.
25594 2004-10-04 Robert Dewar <dewar@gnat.com>
25596 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
25598 (Analyze_Block_Statement): Add circuitry to detect following dead code
25599 (Check_Unreachable_Code): Handle case of block exit
25601 2004-10-04 Robert Dewar <dewar@gnat.com>
25603 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
25604 (XMatchD): Avoid warning for Logic_Error call
25606 2004-10-04 Robert Dewar <dewar@gnat.com>
25608 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
25609 consider expressions buried within a procedure actual to be an actual.
25610 This caused some blowups with uses of packed slices within a procedure
25613 2004-10-04 Robert Dewar <dewar@gnat.com>
25615 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
25616 longer need to be initialized to zero.
25617 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
25618 initialized to zero.
25620 * checks.adb (Expr_Known_Valid): Packed arrays are now always
25621 considered valid, even if the representation is modular. That's correct
25622 now that we no longer initialize packed modular arrays to zero.
25624 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
25625 suffixes. These are now documented as the only cases in which the
25626 debugger ignores outer records.
25627 Previously, the spec allowed arbitrary suffixes for this purpose.
25628 Change name of LJM to JM for packed array pad records
25629 Create separate section on packed array handling, and add a whole new
25630 set of comments to this section describing the situation with packed
25631 modular types and justification requirements depending on endianness.
25633 2004-10-04 Robert Dewar <dewar@gnat.com>
25635 * a-except.adb: Add a comment for last change
25637 * einfo.ads: Minor spelling correction in comment
25639 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
25641 * sem_ch11.adb: Fix a case of using | instead of \ for continuation

25648 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
25649 Inline_Always when in Configurable_Run_Time mode.
25651 * sem_prag.adb (Process_Convention): If entity is an inherited
25652 subprogram, apply convention to parent subprogram if in same scope.
25653 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
25654 when in Configurable_Run_Time mode.
25656 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25658 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
25659 class_wide type after component list has been inherited.

25663 * sem_ch12.adb (Check_Generic_Actuals): New predicate
25664 Denotes_Previous_Actual, to handle properly the case of a private
25665 actual that is also the component type of a subsequent array actual.
25666 The visibility status of the first actual is not affected when the
25667 second is installed.
25668 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
25669 make fully recursive the treatment of formals of packages declared
25671 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
25672 the above on exit from an instantiation.
25673 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
25674 current instantiation which is now complete.
25675 (Analyze_Package_Instantiation): No instantiated body is needed if the
25676 main unit is generic. Efficient, and avoid anomalies when a instance
25677 appears in a package accessed through rtsfind.
25679 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25681 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
25682 do not generate a declaration for a temporary if the call is part of a
25683 library-level instantiation.
25685 2004-10-04 Ed Schonberg <schonberg@gnat.com>
25687 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
25688 searching for a limited component to flag.
25690 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
25691 expansion of Input, to account for the fact that the implicit call
25692 generated by the attribute reference must freeze the user-defined
25693 stream subprogram. This is only relevant to 'Input, because it can
25694 appear in an object declaration, prior to the body of the subprogram.
25696 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
25697 expansion can proceed and further errors uncovered.
25698 (Minor clean up): Fix cases of using | instead of \ for continuation
25701 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
25703 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
25705 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
25706 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
25707 Use gcc_assert and gcc_unreachable.
25709 * decl.c (gnat_to_gnu_entity, case object): Check and process a
25710 specified alignment before validating size.
25711 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
25712 stripped-down declaration for the type of the inner field when making
25715 * utils.c (finish_record_type): Do not compute the size in units
25716 incrementally. Instead compute it once for the rep clause case.
25717 Use gcc_assert and gcc_unreachable.
25719 2004-10-04 Vincent Celier <celier@gnat.com>
25721 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
25723 (Is_Valid_Path_Name): Take '/' as a directory separator.
25725 2004-10-04 Vincent Celier <celier@gnat.com>
25727 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
25728 (Extended_Project) only if Extended_Project is defined, to avoid
25730 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
25732 (Parse_Single_Project): Ditto.
25734 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
25735 Add_To_Project_Path for virtual projects.
25737 2004-10-04 Vincent Celier <celier@gnat.com>
25739 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

25742 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
25743 parameter Options_2.
25745 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
25746 Build_Dynamic_Library with an empty Options_2.
25748 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
25751 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
25752 directory separator, if any.
25753 (Gprmake): Do not allow mains on the command line for library projects.
25754 Do not attempt to link when the project is a library project.
25755 (Library_Opts): New table to store Library_Options.
25756 (Build_Library): If Library_Options is specified, pass these options
25757 when building a shared library.
25759 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
25761 * s-tposen.adb (Service_Entry): The object must be always unlocked at
25762 the end of this procedure now that the unlock operation was inserted
25765 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
25767 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
25768 corresponding to the Preallocated_Stacks flags in System.
25769 (Get_Target_Parameters): Including the processing for
25770 Preallocated_Stacks.

25780 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
25781 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
25782 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
25783 used to signal whether the compiler creates the required stacks and
25784 descriptors for the different tasks (when True) or it is done by the
25785 underlying operating system at run time (when False).
25786 It is initially set to False in all targets.
25788 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
25789 if it is supported by the target.
25790 (Make_Task_Create_Call): Pass the stack address if it has been
25791 previously created. Otherwise pass a Null_Address.
25793 * snames.adb: Add _stack.
25795 * snames.ads: Add Name_uStack. Required to allow the expander to
25796 statically allocated task stacks.
25798 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
25799 Stack_Address argument.
25800 Check that its value is equal to Null_Address because this target does
25801 not support the static stack allocation.
25803 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
25805 * usage.adb: Change "pragma inline" to "pragma Inline" in information

25810 * exp_dist.adb: Split declaration of asynchronous flag out of
25811 Add_RACW_Read_Attribute.
25812 Minor reformatting for better alignment with PolyORB version.
25813 Store the entity for the asynchronous flag of an RACW, rather than the
25814 expression, in the asynchronous flags table. This will allow this flag
25815 to be used in other subprograms beside Add_RACW_Read_Attribute.
25817 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
25819 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

25823 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
25824 sockets constant MSG_NOSIGNAL (Linux-specific).
25825 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
25826 all Send operations.
25827 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
25828 from trigerring SIGPIPE.
25829 Rename components to avoid clash with Ada 2005 possible reserved
25831 (Check_Selector): When the select system call returns with an error
25832 condition, propagate Socket_Error to the caller.
25834 2004-10-01 Jan Hubicka <jh@suse.cz>
25836 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
25838 2004-09-23 Robert Dewar <dewar@gnat.com>
25841 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
25842 instead do this at freeze time (we won't do it if there is an address
25844 Change "pragma inline" to "pragma Inline" in information and error
25846 Minor reformatting.
25848 * freeze.adb (Check_Address_Clause): Remove previous change, not the
25849 right way of doing things after all.
25850 (Freeze_Entity): For object, set Is_Public for imported entities
25851 unless there is an address clause present.
25853 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
25855 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
25856 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
25857 ensures proper handling of types with rep clauses, which might have
25858 their TYPE_SIZE set already.
25860 2004-09-21 Robert Dewar <dewar@gnat.com>
25862 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
25863 packed array types in both little- and big-endian cases. This change
25864 ensures that we no longer count on the unused bits being initialized
25865 for such types (and in particular ensures that equality testing will
25866 only read the relevant bits).
25867 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
25868 These changes mean that we no longer need to initialize small packed
25870 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
25871 optimization to an LJM field as to its parent field.
25873 * ada-tree.h, trans.c, utils.c, utils2.c:
25874 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
25876 2004-09-20 Jan Hubicka <jh@suse.cz>
25878 * utils.c (gnat_finalize): Remove.
25879 (end_subprog_body): Directly call cgraph_finalize_function;
25880 do not lower the nested functions.
25882 2004-09-20 Robert Dewar <dewar@gnat.com>
25885 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
25886 if an address clause is present, since that means that the Import
25889 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
25891 * 5tsystem.ads: Removed, no longer used.
25893 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
25894 Zack Weinberg <zack@codesourcery.com>
25896 * ada-tree.def: Use tree_code_class enumeration constants
25897 instead of code letters.
25898 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
25899 Update for new tree-class enumeration constants.

25914 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
25915 an existing directory.
25916 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
25917 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
25918 Convert the result to File_Size.
25920 * prj.ads: (Project_Error): New exception
25922 * prj-attr.adb: Except in procedure Initialize, Fail comes from
25923 Prj.Com, not from Osint.
25924 (Attrs, Package_Attributes): Tables moved to private part of spec
25925 (Add_Attribute, Add_Unknown_Package): Moved to new child package
25927 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
25928 Prj.Project_Error after call to Fail.
25929 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
25930 Fail. Check that package name is not already in use.
25932 * prj-attr.ads: Comment updates to indicate that all subprograms may be
25933 used by tools, not only by the project manager, and to indicate that
25934 exception Prj.Prj_Error may be raised in case of problem.
25935 (Add_Unknown_Package, Add_Attribute): Moved to new child package
25937 (Attrs, Package_Attributes): Table instantiations moved from the body to
25938 the private part to be accessible from Prj.Attr.PM body.

25941 from new package Prj.Attr.PM.
25942 (Parse_Attribute_Declaration): Call Add_Attribute from new package
25945 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
25947 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
25948 instead of Elaboration_Checks).
25950 * a-calend.adb: Minor reformatting
25952 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

26010 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
26011 Common_ATCB record. It contains the dynamic level of protected action
26012 nesting for each task. It is needed for checking whether potentially
26013 blocking operations are called from protected operations.

26051 contains the required machinery for handling that.
26053 * sem_util.ads: Change comment associated to procedure
26054 Check_Potentially_Blocking_Operation.
26055 This procedure does not insert a call for raising the exception because
26056 that is currently done by the run time.
26058 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
26060 * init.c: Add the global variable __gl_detect_blocking that indicates
26061 whether pragma Detect_Blocking is active (1) or not (0). Needed for
26062 making the pragma available at run time.
26063 (__gnat_set_globals): Pass and update the detect_blocking parameter.
26065 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if

26070 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
26071 DB is found in the ali file. Any unit compiled with pragma
26072 Detect_Blocking active forces its effect in the whole partition.
26074 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
26075 Detect_Blocking is active and delay is called from a protected
26078 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
26079 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
26080 Detect_Blocking is active (0 otherwise).
26081 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
26082 as Detect_Blocking parameter if pragma Detect_Blocking is active (0

26092 (Register_Receiving_Stub): Add Subp_Info formal parameter.
26093 Update API in placeholder implemetation of s-parint to reflect changes
26094 in distribution runtime library.
26096 * sem_ch3.adb (Expand_Derived_Record): Rename to
26097 Expand_Record_Extension.
26099 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
26100 primitive operations of potentially distributed object types that have
26101 non-controlling anonymous access formals.
26103 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
26105 New implementation of expansion for remote access-to-subprogram types,
26106 based on the RACW infrastructure.
26107 This version of sem_dist is compatible with PolyORB/DSA as well as
26110 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
26111 Asynchrronous that applies to a remote access-to-subprogram type, mark
26112 the underlying RACW type as asynchronous.
26114 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
26115 __gnat_using_gnu_linker to 1.
26117 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
26118 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

26124 * exp_ch3.adb (Expand_Derived_Record): Rename to
26125 Expand_Record_Extension.
26126 (Build_Record_Init_Proc.Build_Assignment): The default expression in
26127 a component declaration must remain attached at that point in the
26128 tree so New_Copy_Tree copies it if the enclosing record type is derived.
26129 It is therefore necessary to take a copy of the expression when building
26130 the corresponding assignment statement in the init proc.
26131 As a side effect, in the case of a derived record type, we now see the
26132 original expression, without any rewriting that could have occurred
26133 during expansion of the ancestor type's init proc, and we do not need
26134 to go back to Original_Node.

26144 subprogram. The proxy object is used as the designated object
26145 for RAS values on the same partition (unless All_Calls_Remote applies).
26146 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
26147 System.Partition_Interface.Get_Unique_Remote_Pointer.
26148 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
26149 Renamed from Add_RAS_*_Attribute.
26150 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
26152 New implementation of expansion for remote access-to-subprogram types,
26153 based on the RACW infrastructure.
26155 * exp_dist.ads (Copy_Specification): Update comment to note that this
26156 function can copy the specification from either a subprogram
26157 specification or an access-to-subprogram type definition.
26159 2004-09-09 Ed Schonberg <schonberg@gnat.com>
26161 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
26162 in an instance, between an explicit subprogram an one inherited from a
26163 type derived from an actual.
26165 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
26166 add a polling call if the subprogram is to be inlined by the back-end,
26167 to avoid repeated calls with multiple inlinings.
26169 * checks.adb (Apply_Alignment_Check): If the expression in the address
26170 clause is a call whose name is not a static entity (e.g. a dispatching
26171 call), treat as dynamic.

26175 * g-trasym.ads: Minor reformatting
26177 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

26216 * opt.ads: Add Ada_Version_Runtime constant used to decide which
26217 version of the language is used to compile the run time.

26221 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
26222 of variable length temporaries for function return now that the

26274 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
26275 packed indexed component where array is an IN OUT formal. This

26298 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
26299 pragma Debug as an if statement with a constant condition, for
26300 consistent treatment of entity references contained within the
26301 enclosed procedure call.
26303 2004-09-01 Vincent Celier <celier@gnat.com>
26305 * bindgen.adb: (Set_EA_Last): New procedure

26330 2004-09-01 Pascal Obry <obry@gnat.com>
26332 * gprcmd.adb (Extend): Do not output trailing directory separator. This

26334 directory terminated by a slash as a directory.
26335 (gprcmd): Idem for "pwd" internal command.
26337 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
26338 target names rewrite to fix regressions with recent version of
26339 GNU/make. Starting with GNU/make 3.80 the pipe character was not
26340 handled properly anymore.

26392 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
26393 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
26394 option and not mdll anymore. Update comment.
26396 2004-08-16 Pascal Obry <obry@gnat.com>
26398 * bld.adb (Put_Include_Project): Properly handle directory separators
26401 2004-08-16 Ed Schonberg <schonberg@gnat.com>

26414 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
26416 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
26417 for a global aliased object with a variable size and an unconstrained
26418 nominal subtype, pretend there is no initializer if the one we have is
26419 incomplete, and avoid referencing an inexistant component in there. The
26420 part we have will be rebuilt anyway and the reference may confuse
26421 further operations.

26443 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
26444 unit, this is an attempt to inline a construct that is not available in
26445 the current restricted mode, so abort rather than trying to continue.
26447 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
26448 discriminants that rename those of the parent, recover names of
26449 original discriminants for the constraint on the full view of the
26451 (Complete_Private_Subtype): Do not create a subtype declaration if the
26452 subtype is an itype.
26454 * gnat_rm.texi: Added section on implementation of discriminated
26455 records with default values for discriminants.
26457 2004-08-13 Ed Schonberg <schonberg@gnat.com>

26477 new specification and test explicitly for non-zero return value.
26479 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
26480 returning C.int, to avoid using a derived boolean type.
26482 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

26508 2004-08-09 Olivier Hainque <hainque@act-europe.fr>
26510 * decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Adjust condition to
26511 ignore overflows on low and high bounds of an index to also account for
26512 differences in signedness between sizetype and gnu_index_subtype.
26513 These are as legitimate as the ones caused by a lower TYPE_PRECISION
26516 2004-08-09 Robert Dewar <dewar@gnat.com>
26518 * s-solita.ads, s-solita.adb: Minor reformatting
26520 * gnat_rm.texi: Add documentation for pragma Profile (Restricted)
26521 Move pragma Restricted_Run_Time, No_Run_Time, Ravenscar to new

26524 run time constraint checks.
26526 * vms_conv.ads: Minor reformatting
26528 * s-secsta.adb: Use SS_Ptr instead of Mark_Id as stack pointer (cleanup

26533 * s-secsta.ads: Define SS_Ptr to be used instead of Mark_Id as stack
26534 pointer (cleanup and necessary for following change).
26535 Define Mark_Id as record containing address of secondary stack, that way

29140 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
29141 overriding, use the operation of the parent unconditionally.
29143 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
29144 operation when either operand is a literal, to avoid further
29147 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and

30430 complete assignment subtree which is now unnecessary, as the expansion
30431 of inlined call has been improved to preserve a consistent assignment
30432 tree. Note_Possible_Modification must be called only
30433 after checks have been applied, or else unnecessary checks will

30694 * osint.adb (Executable_Prefix): Set Exec_Name to the current
30695 executable name when not initialized. Otherwise, use its current value.
30697 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
30698 initialize it to another executable name than the current one. This
30699 allows to configure paths for an executable name (gnatmake) different
30700 from the current one (gnatdist).
30702 2004-03-29 Ed Schonberg <schonberg@gnat.com>
30704 * exp_ch6.adb (Expand_Call): A call to a function declared in the
30705 current unit cannot be inlined if it appears in the body of a withed
30706 unit, to avoid order of elaboration problems in gigi.
30708 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
30709 information for protected (wrapper) operation as well, to simplify gdb
30712 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
30713 protected body, indicate that the entity for the generated spec comes
30714 from source, to ensure that references are properly generated for it.

30749 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
30751 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
30752 attribute reference does not denote a subtype, it can be any
30753 expression that has a classwide type, potentially after an implicit
30754 dereference. In particular, the prefix can be a view conversion for
30755 a classwide type (for which Is_Object_Reference holds), but it can
30756 also be a value conversion for an access-to-classwide type. In the
30757 latter case, there is an implicit dereference, and the original node
30758 for the prefix does not verify Is_Object_Reference.
30760 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
30761 conversion of a discriminant-dependent component of a mutable object
30764 2004-03-25 Ed Schonberg <schonberg@gnat.com>
30766 * freeze.adb (Freeze_Entity): When an inherited subprogram is
30767 inherited, has convention C, and has unconstrained array parameters,
30768 place the corresponding warning on the derived type declaration rather
30769 than the original subprogram.

30776 determine whether to generate an implicit or explicit reference to
30777 the renamed entity.

30785 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
30786 value expressions to ensure that calls within a component definition
30787 will be checked (since those are evaluated during the record type's

30839 declaration for a child subprogram body that acts as a spec, indicate
30840 that the entity in the declaration needs debugging information.
30842 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
30843 full view if the subtype is created for a constrained record component;
30844 gigi has enough information to construct the record, and there is no
30845 place in the tree for the declaration.
30847 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
30848 serial number for the dummy body that is built for analysis, to avoid
30849 inconsistencies in the generation of internal names when compiling

30885 * ada-tree.h: Update copyright notice.
30886 Minor reformatting.
30888 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
30890 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
30891 as regular exception objects and not as mere integers representing the
30892 condition code. The latter approach required some dynamics to mask off
30893 severity bits, which did not fit well into the GCC table based model.
30894 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
30895 exception data objects. We don't it and it would conflict with the other
30896 external symbol we have to generate for such exceptions.
30898 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
30899 the special code for VMS exceptions, since these are now represented
30900 as regular exceptions objects.

30942 * init.c [VxWorks]: Do not fix the stack size for the environment task.
30943 When needed (stack checking) the stack size is retrieved
30944 from the VxWorks kernel.
30946 * Makefile.in: Flag -nostdinc is required when building the run time
30947 for avoiding looking for files in the base compiler.
30948 Add the VxWorks specific version of the package body for
30949 System.Stack_checking.Operations (5zstchop.adb).
30951 * Make-lang.in: Add the object file for
30952 System.Stack_Checking.Operations.

30976 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
30977 the procedures Add_To_Path_File.
30978 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
30979 making sure that each directory is present only once and, for object
30980 dirs, when a directory already present is added, the duplicate is

31194 explicit dereference.
31195 (Expand_N_Slice): Same. Always do the rewriting, even for the case
31196 of non-packed slices, since the dereference action generated by

31199 analyze and resolve the rewritten explicit dereference so it is seen
31201 (Insert_Dereference_Action): This procedure is now called only for the

32586 * opt.ads: New parameter Default_Secondary_Stack_Size (GNATBIND)
32587 New switch Sec_Stack_Used (GNAT, GNATBIND)
32588 Make Default_Secondary_Stack_Size a variable instead of a constant,
32589 so that it can be modified by the new -Dnnn bind switch.
32591 * rtsfind.adb (Load_Fail): Give full error message in configurable
32592 run-time mode if all_errors mode is set. This was not done in the case
32593 of a file not found, which was an oversight.
32594 Note if secondary stack unit is used by compiler.
32596 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
32597 ineffective elaborate all pragmas on non-visible packages (this
32598 happened when a renamed subprogram was called). Now the elaborate all
32599 always goes on the package containing the renaming rather than the one
32600 containing the renamed subprogram.
32602 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
32603 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
32605 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
32606 has an Etype that references an E_String_Literal.
32607 (Eval_String_Literal): Avoid assumption that N_String_Literal node
32608 always references an E_String_Literal_Subtype entity. This may not
32609 be true in the future.
32611 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
32614 * sem_res.adb (Resolve): Specialize msg for function name used in proc
32617 2004-01-05 Ed Falis <falis@gnat.com>

32622 2004-01-05 Vincent Celier <celier@gnat.com>
32624 * bld.adb: Minor comment updates
32625 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
32628 * make.adb (Gnatmake): Special process for files to compile/check when
32629 -B is specified. Fail when there are only foreign mains in attribute
32630 Main of the project file and -B is not specified. Do not skip bind/link
32631 steps when -B is specified.
32633 * makeusg.adb: Document new switch -B
32635 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
32637 * switch-m.adb: (Scan_Make_Switches): Process -B switch

32651 has size that overflows.
32653 2004-01-05 Gary Dismukes <dismukes@gnat.com>
32655 * exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
32656 -gnatwa warning on static condition.
32658 2004-01-05 Doug Rupp <rupp@gnat.com>
32660 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
32662 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
32664 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
32665 all attributes, including read-only attribute.

32670 library naming scheme.
32672 * mlib-prj.adb (Build_Library): Generate different names for the static
32673 or dynamic version of the GNAT runtime. This is needed to support the
32674 new shared library naming scheme.
32675 (Process_Binder_File): Add detection of shared library in binder file
32676 based on the new naming scheme.
32678 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
32679 scheme for the shared runtime libraries.
32682 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
32684 (install-gnatlib): Do not create symlinks for shared libraries.
32685 (gnatlib-shared-default): Idem.
32686 (gnatlib-shared-dual-win32): New target. Not used for now as the
32687 auto-import feature does not support arrays/records.
32688 (gnatlib-shared-win32): Do not create copy for the shared libraries.
32689 (gnatlib-shared-vms): Fix shared runtime libraries names.
32691 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
32692 dependent runtime shared library name.
32694 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
32696 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
32699 2004-01-05 Ed Schonberg <schonberg@gnat.com>
32701 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
32702 protected objects when allocator has a subtype indication, not a
32703 qualified expression. Note that qualified expressions may have to be
32704 checked when limited aggregates are implemented.
32706 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
32707 pure, emit warning.
32708 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
32709 subprogram is imported, remove warning.
32711 2004-01-05 Geert Bosch <bosch@gnat.com>
32713 * s-poosiz.adb: Update copyright notice.
32714 (Allocate): Use Task_Lock to protect against concurrent access.
32715 (Deallocate): Likewise.

32749 Ada.Exceptions.Last_Chance_Handler.
32751 2003-12-17 Sergey Rybin <rybin@act-europe.fr>
32753 * cstand.adb (Create_Standard): Change the way how the declaration of
32754 the Duration type is created (making it the same way as it is for all
32755 the other standard types).
32757 2003-12-17 Robert Dewar <dewar@gnat.com>
32759 * s-crtl.ads: Fix header format
32760 Change Pure to Preelaborate
32762 2003-12-17 Ed Schonberg <schonberg@gnat.com>
32764 * checks.adb (Selected_Length_Checks): Generate an Itype reference for
32765 the expression type only if it is declared in the current unit.
32767 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
32768 are universal and already analyzed, as can occur in constrained
32769 subcomponents that depend on discriminants, when one constraint is a
32772 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
32773 type Any_Fixed is legal as the argument of a conversion, if only one
32774 fixed-point type is in context.
32776 2003-12-17 GNAT Script <nobody@gnat.com>

32785 2003-12-15 Vincent Celier <celier@gnat.com>
32787 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
32788 (Gnatchop): Do not set failure status when reporting the number of
32791 2003-12-15 Doug Rupp <rupp@gnat.com>
32793 * s-ctrl.ads: New file.
32795 * Makefile.rtl (GNAT_RTL_NONTASKING_OBJS): Add s-crtl$(objext).

32815 2003-12-11 Ed Falis <falis@gnat.com>
32817 * 5zinit.adb: Clean up.
32819 * 5zintman.adb (Notify_Exception): replaced case statement with a call
32820 to __gnat_map_signal, imported from init.c to support
32821 signal -> exception mappings that depend on the vxWorks version.
32824 Created and exported __gnat_map_signal to support signal -> exception
32825 mapping that is dependent on the VxWorks version.
32826 Change mapping of SIGBUS from Program_Error to Storage_Error on VxWorks
32828 2003-12-11 Vasiliy Fofanv <fofanov@act-europe.fr>

32840 * Makefile.in (rts-zfp, rts-ravenscar): Create libgnat.a.
32842 2003-12-11 Thomas Quinot <quinot@act-europe.fr>
32844 * sinfo.ads: Fix inconsistent example code in comment.
32846 2003-12-11 Robert Dewar <dewar@gnat.com>
32848 * a-tiinau.adb: Add a couple of comments
32850 * sem_ch3.adb: Minor reformatting
32853 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
32854 Minor reformatting throughout
32856 2003-12-11 Ed Schonberg <schonberg@gnat.com>
32858 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
32859 bounds of a loop, create a separate block in order to generate proper
32860 cleanup actions to prevent memory leaks.
32862 * sem_res.adb (Resolve_Call): After a call to
32863 Establish_Transient_Scope, the call may be rewritten and relocated, in
32864 which case no further processing is needed.
32866 * sem_util.adb: (Wrong_Type): Refine previous fix.

32876 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
32879 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
32882 2003-12-08 Robert Dewar <dewar@gnat.com>
32884 * 7sintman.adb: Minor reformatting
32886 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
32887 standard linker options to get standard libraries linked. We now plan
32888 to provide dummy versions of these libraries to match the appropriate
32889 configurable run-time (e.g. if a library is not needed at all, provide
32890 a dummy empty library).
32892 * targparm.ads: Configurable_Run_Time mode no longer affects linker
32893 options (-L parameters and standard libraries). What we plan to do is
32894 to provide dummy libraries where the libraries are not required.
32896 * gnatbind.adb: Minor comment improvement
32898 2003-12-08 Javier Miranda <miranda@gnat.com>
32900 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
32901 aggregate in the parent. Otherwise constants with limited aggregates
32902 are not supported. Add new formal to pass the component type (Ctype).
32903 It is required to call the corresponding IP subprogram in case of
32904 default initialized components.
32905 (Gen_Assign): In case of default-initialized component, generate a
32906 call to the IP subprogram associated with the component.
32907 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
32908 of aggregate with default initialized components.
32909 (Has_Default_Init_Comps): Improve implementation to recursively check
32910 all the present expressions.
32912 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
32913 to indicate that the initialization call corresponds to a
32914 default-initialized component of an aggregate.
32915 In case of default initialized aggregate with tasks this parameter is
32916 used to generate a null string (this is just a workaround that must be
32917 improved later). In case of discriminants, this parameter is used to
32918 generate a selected component node that gives access to the discriminant
32921 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
32922 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
32923 allocated aggregates with default-initialized components.
32925 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
32926 the box notation is used in positional aggregates.
32928 2003-12-08 Samuel Tardieu <tardieu@act-europe.fr>

32943 (Parse): New Boolean parameter Store_Comments, defaulted to False.
32944 Set the scanner to return ends of line and comments as tokens, if
32945 Store_Comments is True.
32946 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
32947 comments are associated with these nodes. Store the node IDs in the
32949 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
32951 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
32952 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
32953 current project. Call Tree.Restore afterwards. Set the various nodes
32954 for comment storage (Next_End, End_Of_Line, Previous_Line,
32957 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
32958 defaulted to False.
32960 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
32961 to False. When Truncated is True, truncate the string, never go to the
32963 (Write_End_Of_Line_Comment): New procedure
32964 (Print): Process comments for nodes N_With_Clause,
32965 N_Package_Declaration, N_String_Type_Declaration,
32966 N_Attribute_Declaration, N_Typed_Variable_Declaration,
32967 N_Variable_Declaration, N_Case_Construction, N_Case_Item.
32968 Process nodes N_Comment.
32970 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
32971 without comments and there are some comments, set the flag
32972 Unkept_Comments to True.
32973 (Scan): If there are comments, set the flag Unkept_Comments to True and
32974 clear the comments.
32975 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
32976 (Next_End_Nodes: New table
32977 (Comment_Zones_Of): New function
32978 (Scan): New procedure; moved from Prj. Accumulate comments in the

32993 (Set_First_Comment_Before, Set_First_Comment_Before_End): New procedures
32994 (Set_Next_Comment): New procedure
32995 (Default_Project_Node): Associate comment before if the node can store

32999 (Comment_Id): New global variable
33001 * scng.ads, scng.adb (Comment_Is_Token): New Boolean global variable,
33002 defaulted to False.
33003 (Scan): Store position of start of comment. If comments are tokens, set
33004 Comment_Id and set Token to Tok_Comment when scanning a comment.
33005 (Set_Comment_As_Token): New procedure
33007 * sinput-p.adb: Update Copyright notice
33008 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
33009 that no longer exists.
33011 2003-12-08 Javier Miranda <miranda@gnat.com>
33013 * sem_aggr.adb: Add dependence on Exp_Tss package
33014 Correct typo in comment
33015 (Resolve_Aggregate): In case of array aggregates set the estimated
33016 type of the aggregate before calling resolve. This is needed to know
33017 the name of the corresponding IP in case of limited array aggregates.
33018 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
33019 in case of default initialized array components.
33021 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited
33022 types. Required to give support to limited aggregates in generic
33025 2003-12-08 Ed Schonberg <schonberg@gnat.com>
33027 * sem_ch3.adb (Check_Initialization): For legality purposes, an
33028 inlined body functions like an instantiation.
33029 (Decimal_Fixed_Point_Declaration): Do not set kind of first subtype
33030 until bounds are analyzed, to diagnose premature use of type.
33032 * sem_util.adb (Wrong_Type): Improve error message when the type of
33033 the expression is used prematurely.
33035 2003-12-08 GNAT Script <nobody@gnat.com>
33037 * Make-lang.in: Makefile automatically updated
33039 2003-12-08 Arnaud Charlet <charlet@act-europe.fr>
33041 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
33042 they are automatically generated by Make-lang.in and cause nothing but
33043 maintenance troubles.
33045 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
33047 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

33055 the body of System.Interrupt_Management common to several targets.
33056 Update copyright notice when appropriate.
33058 * 52osinte.ads, 5posinte.ads: Define a dummy value for the SA_SIGINFO
33061 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
33062 to ensure that the kernel fills in the interrupted context structure
33063 before calling a signal handler, which is necessary to be able to
33064 unwind past it. Update the copyright notice.
33066 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
33068 * a-elchha.ads: New file.
33070 * a-elchha.adb: New default last chance handler. Contents taken from
33071 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.
33073 * a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine
33074 is moved to a-elchha.adb to provide a target-independent default last
33077 * Makefile.rtl: Add a-elchha.o
33079 * Make-lang.in (GNAT_ADA_OBJS, GNATBIND_OBJS): Add a-elchha.o.

33083 * exp_ch6.adb (Expand_Call): If the subprogram is inlined and is
33084 declared in an instance, do not inline the call if the instance is not
33085 frozen yet, to prevent order of elaboration problems.
33087 * sem_prag.adb: Add comments for previous fix.
33089 2003-12-05 Samuel Tardieu <tardieu@act-europe.fr>
33091 * g-table.adb: Use the right variable in Set_Item.
33092 Update copyright notice.

33100 * switch-c.adb (Scan_Front_End_Switches): Remove processing of
33101 -nostdlib. Not needed here after all.
33103 2003-12-03 Thomas Quinot <quinot@act-europe.fr>
33106 * adaint.h, adaint.c, g-os_lib.ads:
33107 Do not assume that the offset argument to lseek(2) is a 32 bit integer,

34522 Remove the test against being in No_Run_Time_Mode before generating a
34523 call to Register_Tag. It is redundant with the test against the
34524 availability of the function Register_Tag.

36702 C front end but not used, or used only to permit the compiler
36705 2002-02-07 Richard Henderson <rth@redhat.com>
36707 * adaint.c (__gnat_to_gm_time): First arg is int, not time_t.

36710 2002-01-30 Richard Henderson <rth@redhat.com>
36712 * trans.c (tree_transform) [N_Loop_Statement]: Use
36713 expand_exit_loop_top_cond.

36724 2001-12-23 Florian Weimer <fw@deneb.enyo.de>
36726 * gnat-style.texi (Declarations and Types): Remove ancient style
36727 rule which was mandated by code generation issues.
36729 * gnat-style.texi (header): Add @dircategory, @direntry.
36730 (title page): Remove date.
36731 (general) Add @./@: where approriate, and two spaces after the
36732 full stop at the end of a sentence. Use @samp markup when
36733 referring concrete lexical entities (keywords, attribute names
36734 etc.), and @syntax for ARM grammar elements. Use @r for English
36735 text in comments. Use @emph for emphasis. Change "if-statements"
36736 etc. to "if statements" (without @samp). Break long lines. Make
36737 casing of section names consistent.
36738 (Identifiers): Use @samp markup for variable names.
36739 (Comments): Use @samp markup for comment characters. Line-end
36740 comments may follow any Ada code, not just statements. Fix
36741 misspelling of "Integer" as "integer".
36742 (Loop statements): Do not use variable name "I", use "J".

36747 2001-12-22 Florian Weimer <fw@deneb.enyo.de>
36749 * make.adb (Add_Switch): Make Generic_Position a procedure. The
36750 function approach did not work well because of a side effect (the
36751 function call could reallocate the table which was being indexed
36752 using its result). Fixes ada/4851.
36754 2001-12-19 Robert Dewar <dewar@gnat.com>

36785 error found (there were odd exceptions to this general rule in
36786 -gnatec/-gnatem processing)
36788 2001-12-19 Olivier Hainque <hainque@gnat.com>
36790 * raise.c (__gnat_eh_personality): Exception handling personality
36791 routine for Ada. Still in rough state, inspired from the C++ version
36792 and still containing a bunch of debugging artifacts.
36793 (parse_lsda_header, get_ttype_entry): Local (static) helpers, also
36794 inspired from the C++ library.
36796 * raise.c (eh_personality): Add comments. Part of work for the GCC 3
36797 exception handling integration.
36799 2001-12-19 Arnaud Charlet <charlet@gnat.com>

37119 2001-12-17 Laurent Pautet <pautet@gnat.com>
37122 Fix comment of Shutdown_Socket and Close_Socket. These functions
37123 should not fail silently because if they are called twice, this
37124 probably means that there is a race condition in the user program.
37125 Anyway, this behaviour is consistent with the rest of this unit.
37126 When an error occurs, an exception is raised with the error message
37127 as exception message.

38516 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
38517 Source_CRC in S initialization.

38521 * sinput.ads (Source_Checksum): renamed to Source_CRC.
38522 Update comments for the CRC.
38524 * types.adb (Hex): Use lowercase for the letter part.
38526 * types.ads (Get_Hex_String): Returns the hexadecimal representation
38527 for a word. This is currently used only for CRC. In previous version,
38528 the checksum was using a representation with all letter being
38529 upper-case. With the new implementation (using CRC) we do not remove
38530 the 32th bit of the CRC, so we can have an upper-case starting letter
38531 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
38532 It is ambigous since the CRC was optional and could be followed by
38533 options like EB, EE. So now this routines uses lower-case letter for
38534 the hexadecimal representation. Strange enough only lower case letters
38535 where checked in Scan_ALI (even if this was not a possible case).
