1290 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
1291 convention from its base type, do not set the type to that of integer,
1292 because it may inherit a size clause.

1356 the visible part of the spec of a remote types unit.

1358 New local subprogram Is_Valid_Remote_Object_Type, replaces
1359 Is_Recursively_Limited_Private.
1360 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
1361 non-controlling formals (and the return type, even though this is not
1362 explicit in the standard) must support external streaming.

1364 as above for of RAS types and RCI subprograms. (The return type is not

1369 * sem_util.ads, sem_util.adb
1370 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
1371 Is_Remote_Call_Interface to identify RACW types in a stable and
1372 consistent way. We used to rely in this predicate on the privateness of
1373 the designated type and its ancestors, but depending on the currently
1374 visible private parts, this caused false negatives. We now uniformly
1375 rely on checks made at the point where the RACW type is declared.

1389 Add missing escaping of all-caps word 'CPP' in error messages.
1390 (Build_Discriminated_Subtype): Do not inherit representation clauses
1391 from parent type if subtype already carries them, because they are
1392 inherited earlier during derivation and already include those that may
1393 come from a partial view.
1395 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
1396 Check the declarations of a subprogram body for proper deferred

1431 operation of an RACW stub type (these primitives are only executed
1432 through dispatching, never through static calls).
1433 (Collect_Interps): When only one interpretation has been found, set N's
1434 Entity and Etype to that interpretation, otherwise Entity and Etype may
1435 still refer to an interpretation that was ignored by Add_One_Interp,
1436 in which case would end up with being marked as not overloaded but with
1437 an Entity attribute not pointing to its (unique) correct interpretation.

1496 equivalent representation, but has the advantage of allowing
1497 compilation of this file under 64 bits platforms.

5562 clauses for inherited components of a type extension.
5563 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for

5697 WITH clause on a private sibling.
5698 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
5699 child unit is a renaming, create an implicit with_clause on that

5804 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
5805 Timed_Entry_Call): Analyze the triggering statement as the first step of
5806 the processing. If this is a dispatching select, postpone the analysis

5809 replicated some of the select statements. In case the Expander is
5810 disabled, perform regular analysis.
5811 (Check_Triggering_Statement): New routine.
5812 (Analyze_Requeue): Exclude any interpretations that are not entries when
5813 checking overloaded names in a requeue. Also test type conformance for

6409 multiple inherited interfaces info. This information cannot be stored
6410 in Xref_Entity_Record, which only supports a single instance of Tref_*,

6427 additional management on these nodes in Expand_Interface_Actuals.
6429 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
6430 that handles use of 'Access and 'Unchecked_Access applied to
6431 actuals covering interface types. Such code is now
6432 centralized in Expand_N_Attribute_Reference.

6476 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
6477 used by VxWorks targets to have access to task-specific data and be
6478 able to extract the stack boundaries for stack checking.

6522 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
6523 association for an access component, add an association with null as
6524 the expression. Remove testing for array subtypes and the setting in
6525 that case of Ctyp to the array component type, which prevented proper
6526 inclusion of an association for null-initialized arrays. Collapse
6527 condition that tests for array subtypes into just a test of
6528 Is_Partially_Initialized_Type (which already covers arrays anyway).

6545 * sem_ch4.adb: Minor code and comment reformatting.
6546 (Analyze_Allocator): When the designated type of an unconstrained
6547 allocator is a record with unknown discriminants or an array with

6678 (gigi): Rename and change type of number_units parameter, change
6679 type of file_info_ptr parameter.
6680 * trans.c (number_files): New global variable.
6681 (gigi): Rename and change type of number_units parameter, change
6682 type of file_info_ptr parameter.
6683 If mapped location support is enabled, create the isomorphic mapping
6684 between source files and line maps.
6685 (Sloc_to_locus): If mapped location support is enabled, translate
6686 source location into mapped location.
6687 (annotate_with_node): Rename into set_expr_location_from_node.

6713 * a-calend-vms.adb, a-calend.adb:
6714 Add a section on leap seconds control along with two entities used to
6715 enable and disable leap seconds support. The array Leap_Second_Times is
6716 now constant and contains hard time values pre-generated. Remove
6717 all elaboration code used to populate the table of leap seconds.
6720 Add entity Leap_Seconds_Support to the list of global run-time variables
6721 along with a comment on its usage and values.
6722 (Gen_Adainit_Ada): Add code to generate the declaration and import of

6736 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
6737 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
6739 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
6741 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
6742 function which can be called by the debugger to interrupt the tasks of
6743 an Ada application asynchronously, as needed on VxWorks.
6744 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
6746 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,

6777 2007-09-26 Javier Miranda <miranda@adacore.com>
6778 Eric Botcazou <ebotcazou@adacore.com>
6781 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
6782 indirection added to the HT_Link component of the TSD. This is required
6783 to statically allocate the TSD.
6786 Minor reordering of the declarations in the private part. Required to
6787 add a level of indirection to the contents of the TSD component HT_Link.
6788 This is required to statically allocate the TSD.
6790 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
6791 Is_Statically_Allocated set from constant objects.
6792 Do not make exported constants created by the compiler volatile.
6793 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
6796 * trans.c (Identifier_to_gnu): For constants, unshare initializers
6797 before returning them.
6799 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
6800 public part of the package.
6801 (Make_DT): Move HT_Link component out of the TSD record. For this
6802 purpose Make_DT now declares a separate object that stores the
6803 HT_Link value, and initializes the TSD component with the address
6804 of this new object. The addition of this level of indirection is
6805 required to statically allocate the TSD because the TSD cannot
6806 have variable components.
6807 (Expand_Interface_Conversion): Improve the expanded code.
6808 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
6810 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
6811 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
6812 if we are building static dispatch tables then we must not generate
6813 extra code to register the primitive because the dispatch table will
6814 be built at the end of the library package; otherwise we notify that
6815 we cannot build the static dispatch table.
6817 2007-09-26 Robert Dewar <dewar@adacore.com>
6819 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
6822 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
6823 (Analyze_Record_Representation_Clause): Suppress junk warning for
6824 missing component clause.

6826 tests for controlled type overlay to composites with controlled
6828 (Analyze_Record_Representation_Clause): Add reference for component name
6830 2007-09-26 Javier Miranda <miranda@adacore.com>
6831 Gary Dismukes <dismukes@adacore.com>

6834 for thunks associated with interface types.
6836 * einfo.ads: Improve documentatation of Is_Internal
6837 (Is_Thunk): New attribute applicable to subprograms. True for thunks
6838 associated with interface types.
6839 Extensive comment fixes regarding flags that appear in all entities. The
6840 documentation is now consistent for all such flags (there were a number
6841 of errors in the documentation in this regard).
6843 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
6845 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
6846 of these procedures are passed a function call that already has
6847 build-in-place actuals (testing new flag
6848 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
6849 the case where processing continues.
6850 (Expand_Call): If the call is generated from a thunk body then we
6851 propagate the extra actuals associated with the accessibility
6852 level of the access type actuals.
6854 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
6855 of each extra formal of a protected operation to reference the
6856 corresponding extra formal of the subprogram denoted by the
6857 operation's Protected_Body_Subprogram.
6859 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
6860 N_Function_Call nodes.
6862 2007-09-26 Robert Dewar <dewar@adacore.com>
6864 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
6866 * debug.adb: Add d.s flag.
6868 2007-09-26 Gary Dismukes <dismukes@adacore.com>
6870 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
6871 debug variable so that it won't be initialized when pragma
6872 Initialize_Scalars is in effect.
6874 2007-09-26 Gary Dismukes <dismukes@adacore.com>
6876 * freeze.adb (Freeze_Entity): Remove check for preelaborable
6877 initialization of a full view. This is moved to
6878 Analyze_Package_Specification.
6880 * sem_ch7.adb (Analyze_Package_Specification): Add check for
6881 preelaborable initialization of a full view in entity loop.
6882 (Uninstall_Declarations): If entity is a use-visible compilation unit,
6883 its child units are use-visible only if they are visible child units.
6885 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
6886 whether an expression can be used within a type declaration that
6887 requires preelaborable init.
6888 (Check_Components): Replace inline code that does partial checking for
6889 preelaborable default expressions with call to
6890 Is_Preelaborable_Expression.
6891 (Has_Preelaborable_Initialization): In the case of a generic actual
6892 subtype, (that is, Is_Generic_Actual is True), return the result of
6893 applying Has_Preelaborable_Initialization to the generic actual's base
6896 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
6898 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
6899 call to Jan_1_Day _Of_Week to optimize its performance.
6900 (Is_Leap): Move the routine to the scope of Week_In_Year.
6901 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
6902 weekday on which January 1 falls of Year - 1 and Year + 1. This function
6903 avoids calling Time_Of and Split, thus making it more efficent.
6904 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
6906 * g-calend.ads (Week_In_Year): Change comment to reflect new
6909 2007-09-26 Emmanuel Briot <briot@adacore.com>
6911 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
6912 Command_Line): New types
6913 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
6914 support for defining how switches can be grouped on a command line (as
6915 is the case for -gnatw... for GNAT), and how simple switches can be
6916 used as aliases for more complex switches (-gnatwa is same as
6918 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
6919 (Start, Current_*): New subprograms
6920 Added support for parsing an array of strings in addition to the real
6922 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
6923 be moved from the body to the private part of the spec.
6924 (*): All subprograms now have an extra parameter with default value to
6925 specify which parser should be used. For backward compatibility, it
6926 defaults to parsing the command line of the application. They were also
6927 modified to properly handle cases where each of the argument does not
6928 start at index 1 (which is always true for Ada.Command_Line, but not
6929 when processing any Argument_List).
6930 (Free): New subprogram
6931 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
6932 Argument): New subprograms
6933 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
6934 special characters like ':', '=',... are now handled in a single place,
6935 which makes the code more extensible eventually.
6936 (Getopt, Full_Switch): When the switch was returned as part of the
6937 special character '*', make sure it is prepended by the switch character
6938 ('-' in general), so that the application knows whether "foo" or "-foo"
6939 was specified on the command line.
6941 2007-09-26 Florian Villoing <villoing@adacore.com>
6943 * g-dirope.adb (Remove_Dir): In case we are removing directories
6944 recursively, make sure that if an exception is raised during the
6945 processing, the current working directory is reset to its initial
6946 value before propagating the exception.
6948 2007-09-26 Vincent Celier <celier@adacore.com>
6950 * gnatbind.adb: If there are several ALI files specified and there is
6951 a main program to bind, the first ALI is expected to contain the main
6952 subprogram and the names of the binder generated files will be derived
6953 from the first ALI file name.
6954 (Gnatbind): Fix insertion character in invocation of Error_Msg
6956 2007-09-26 Vincent Celier <celier@adacore.com>
6958 * gnatcmd.adb (Check_Files): Do not include sources that have been
6959 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
6961 2007-09-26 Ed Schonberg <schonberg@adacore.com>
6963 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
6964 information about each of its index types, following the type
6965 reference for its component type.
6967 2007-09-26 Vincent Celier <celier@adacore.com>
6969 * make.adb: (Kill): New procedure (__gnat_kill imported)
6970 (Running_Compile, Outstanding_Compiles): Global variables that
6971 were previously local to procedure Compile_Sources.
6972 (Sigint_Intercepted): Send signal SIGINT to all outstanding
6973 compilation processes.
6975 (Gnatmake): If project files are used, create the mapping of all the
6976 sources, so that the correct paths will be found.
6978 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
6980 2007-09-26 Vincent Celier <celier@adacore.com>
6982 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
6984 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
6985 Replace components Compiler_Min_Options and Binder_Min_Options with
6986 Compiler_Required_Switches and Binder_Required_Switches in record
6988 Remove components Default_Language and Config in Project_Tree_Data,
6991 * prj-attr.adb: New attributes Required_Switches (<language>) in
6992 packages Compiler and Binder.
6994 * prj-nmsc.adb: Major rewrite of the processing of configuration
6995 attributes for gprbuild. No impact on GNAT tools.
6997 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
6998 process configuration attributes: this is done in Prj.Nmsc.Check.
6999 (Recursive_Process): Make a full copy of packages inherited from project
7000 being extended, instead of a shallow copy.
7001 (Process_Project_Tree_Phase_1): New procedure
7002 (Process_Project_Tree_Phase_1): New procedure
7003 (Process): Implementation now uses the two new procedures
7005 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
7006 from the project config, not the tree config that no longer exists.
7008 2007-09-26 Vincent Celier <celier@adacore.com>

7026 * sem_attr.adb (Analyze_Access_Attribute): Fix missing set of
7029 2007-09-26 Ed Schonberg <schonberg@adacore.com>
7031 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
7032 ancestor of the derived type, the operations are inherited from the
7033 primary dispatch table of the parent.
7034 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
7035 when the context is an explicit type conversion.
7037 2007-09-26 Ed Schonberg <schonberg@adacore.com>
7039 * sem_ch4.adb (Analyze_Qualified_Expression): Apply name resolution
7040 rule for qualified expressions properly, to detect improper conversions

7081 * makegpr.adb (Link_Executables): Do not fail when the root project has
7082 no sources, but is an extending project.
7084 2007-09-25 Eric Botcazou <ebotcazou@adacore.com>
7086 * trans.c: Fix misplaced #define.
7088 2007-09-22 Eric Botcazou <ebotcazou@adacore.com>
7090 * utils2.c (build_unary_op) <ADDR_EXPR> [INDIRECT_REF]: Propagate
7091 the TYPE_REF_CAN_ALIAS_ALL flag to the result.

7339 body for 'Output when the type is abstract (only the creation of the
7340 body for 'Input is excluded when the type is abstract).

7346 variable, insert init proc call only after the shared variable
7347 procedures have been processed, because the IP call needs to undergo

7365 to remove other spurious ambiguities on arithmetic operations involving
7366 literals and addresses, on systems where Address is a visible integer

7533 access type points to an unconstrained array.
7535 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
7537 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
7540 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect
7541 simple redundant qualifications. The check is performed whenever the
7542 expression is a non-overloaded identifier.
7543 (Resolve_Type_Conversion): Enchance the redundant type conversion check
7544 to include loop parameters.
7545 (Valid_Conversion): Avoid generation of spurious error message.
7547 2007-08-31 Bob Duff <duff@adacore.com>
7549 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
7550 concatenations of string literals into a single literal, in order to
7551 avoid very deep recursion in the front end, which was causing stack
7554 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
7555 string, and the right operand is a string literal (the case of "" &
7556 "..."), optimize by avoiding copying the right operand -- just use the
7557 value of the right operand directly.
7559 * stringt.adb (Store_String_Chars): Optimize by growing the
7560 String_Chars table all at once, rather than appending characters one by
7562 (Write_String_Table_Entry): If the string to be printed is very long,
7563 just print the first few characters, followed by the length. Otherwise,
7564 doing "pn(n)" in the debugger can take an extremely long time.
7566 * sem_prag.adb (Process_Interface_Name): Replace loop doing
7567 Store_String_Char with Store_String_Chars.
7569 2007-08-31 Vincent Celier <celier@adacore.com>

7581 clauses of subunits, ignore limited_with_clauses that are illegal and
7582 have not been fully analyzed.
7584 2007-08-31 Ed Schonberg <schonberg@adacore.com>
7586 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
7587 flag, for effiency. It is called when analyzing arithmetic operators
7588 and also for actuals in calls that are universal_integers. The flag is
7589 set for the predefined type address, and for any type or subtype
7592 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
7593 Universal_Integer, when the formal is a descendent of address and the
7594 call appears in user code.
7595 (Analyze_Selected_Component): if the prefix is a private extension, the
7596 tag component is visible.
7598 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an
7601 2007-08-31 Robert Dewar <dewar@adacore.com>
7603 * s-fileio.adb (Open): Normalize file name to lower case in non-case
7604 sensitive file name systems to avoid unexpected mismatch in Vista.

7641 * gnat_ugn.texi: Add description for the new gnatpp
7642 '--separate-stmt-name' and '--use-on-new-line' options.

7655 2007-08-16 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
7657 * misc.c (gnat_type_max_size): Constify.
7659 2007-08-16 Gary Dismukes <dismukes@adacore.com>
7661 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
7662 associated with Standard_Debug_Renaming_Type, to be used as the type of
7663 the special variables whose names provide debugger encodings for
7664 renaming declarations.
7666 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
7667 (Set_Debug_Renaming_Link): Change to set Node25.
7668 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
7669 (Write_Field25_Name): Add case for E_Variable to output
7670 "Debug_Renaming_Link".
7671 (Write_Field23_Name): Correct the output string for "Limited_View".
7673 * exp_dbug.adb: Add with and use of Tbuild.
7674 (Debug_Renaming_Declaration): Replace creation of an enumeration type
7675 and literal with creation of a variable of type
7676 Standard_Debug_Renaming_Type whose name encodes both the renamed object
7677 and the entity of the renaming declaration.
7678 (Qualify_Entity_Name): Add the delayed qualification of the entity name
7679 part of the name of a variable that has a Debug_Renaming_Link.
7681 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
7682 special type to be associated with variables that provide debugger

7686 Ed Schonberg <schonberg@adacore.com>
7687 Javier Miranda <miranda@adacore.com>
7689 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
7690 ancestor part given by an aggregate to test for an unchecked conversion,
7691 since this can occur in some cases when the ancestor part is a function
7692 call, and we don't want to fall into the recursive call to this
7693 procedure in that case.
7695 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
7696 stream attributes on limited types to account for user-specified
7697 attributes as well as whether Input (resp. Output) becomes available
7698 due to Read (resp. Write) being available for the type. Change Boolean
7699 variable to the more accurate name
7700 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
7701 double-"not" predicate at beginning of return statement to more
7702 understandable form.
7704 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
7705 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
7706 in a block statement and use that as the first statement of the
7707 expanded return rather than incorrectly using the handled sequence as
7708 the first statement.
7710 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
7711 operation, generate an explicit freeze node for it rather than
7712 generating extra formals, to ensure that gigi has the proper order of
7713 elaboration for anonymous subtypes in the signature of the subprograms.
7714 (Build_In_Place_Formal): Move assertion to beginning of loop.
7715 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
7716 applied to a function call (occurs for some cases of 'Input).
7717 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
7718 applied to a function call (occurs for some cases of 'Input).
7720 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
7721 2005, generate an extended return statement enclosing the result object
7724 * freeze.adb (Freeze_Record_Type): Extend the current management of
7725 components that are access type with an allocator as default value: add
7726 missing support to the use of qualified expressions of the
7727 allocator (which also cause freezing of the designated type!)
7728 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
7729 dispatching operation, since extra formals may be needed by calls to
7730 build-in-place functions (such as stream 'Input).
7732 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
7733 formals for 'Constrained and accessibility level in the case of a
7734 predefined dispatching operation.
7736 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
7737 point, no need to find the parent node.
7739 2007-08-16 Javier Miranda <miranda@adacore.com>
7741 * exp_attr.adb (Attribute_Priority): Add missing support for entries
7744 2007-08-16 Javier Miranda <miranda@adacore.com>
7746 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
7747 is not really required and can introduce regression with the debugger.
7748 The original problem is fixed with the patch written for checks.adb.
7750 2007-08-16 Thomas Quinot <quinot@adacore.com>
7752 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

7758 Including_Non_Switch set to False.
7759 (Gnatmake): For the compiler, call Test_If_Relative_Path with
7760 Including_Non_Switch set to False.
7762 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
7763 parameter Including_Non_Switch, defaulted to True. When
7764 Including_Non_Switch is False, options that are not switches and
7765 appear as relative path are not converted to absolute paths.
7767 2007-08-16 Nicolas Roche <roche@adacore.com>
7769 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
7772 * Make-lang.in: Update dependencies

7777 currently inspected is a selected component, retrieve the entity of
7779 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
7780 from the immediate ancestor of Main_Unit_Entity.
7781 (Install_Limited_Withed_Unit): Do not install the limited view of
7782 package P if P is reachable through an ancestor chain from package C
7783 and C also has a with clause for P in its body.
7784 (Has_Limited_With_Clause): New routine.
7785 (Has_With_Clause): New routine.
7787 2007-08-16 Ed Schonberg <schonberg@adacore.com>
7789 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
7790 generic for an enclosing instance is a global reference, even though
7791 its scope is the enclosing instance.
7793 2007-08-16 Gary Dismukes <dismukes@adacore.com>
7794 Javier Miranda <miranda@adacore.com>
7796 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
7797 initialize a limited object.
7798 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
7800 Make sure Has_Complex_Representation is inherited by derived type.

7804 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
7807 2007-08-16 Ed Schonberg <schonberg@adacore.com>
7809 * sem_disp.adb (Check_Dispatching_Operation): If the operation
7810 implements an operation inherited from a progenitor interface, verify
7811 that they are subtype-conformant.
7813 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
7814 Bob Duff <duff@adacore.com>
7815 Nicolas Setton <setton@adacore.com>
7817 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
7818 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
7819 the statement which is being resolved comes from a predefined library
7820 unit, all non-predefined library interpretations are skipped.
7821 (Resolve_Op_Concat): If string concatenation was folded in the parser,
7822 but the "&" is user defined, give an error, because the folding would
7825 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
7826 the parser has folded a long sequence of concatenations of string
7829 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
7830 and "JMP_BUF" variables as artificial.
7831 (N_String_Literal): Do not use alloca for very long string literals. Use
7832 xmalloc/free instead. Otherwise the stack might overflow.
7834 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
7837 2007-08-16 Vincent Celier <celier@adacore.com>
7839 * vms_conv.adb (Process_Argument): Ensure that project related options
7840 are not put in the -cargs section when using GNAT COMPILE.
7842 2007-08-16 Robert Dewar <dewar@adacore.com>
7844 * gnat_ugn.texi: Add note on preprocessing (output file not written)
7846 2007-08-16 Thomas Quinot <quinot@adacore.com>

7877 Ed Schonberg <schonberg@adacore.com>
7879 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
7880 Suppress unmodified in-out parameter warning in some cases
7881 This patch is a also fairly significant change to the way suppressible
7884 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
7885 needed for access to concurrent record types generated by the expander.
7886 (Generate_Range_Check): When generating a temporary to capture the
7887 value of a conversion that requires a range check, set the type of the
7888 temporary before rewriting the node, so that the type is always
7889 properly placed for back-end use.
7890 (Apply_Float_Conversion_Check): Handle case where the conversion is
7892 (Get_Discriminal): Code reformatting. Climb the scope stack looking
7893 for a protected type in order to examine its discriminants.

7904 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
7905 (Get_Allocator_Final_List): For the case of an anonymous access type
7906 that has a specified Associated_Final_Chain, do not go up to the
7908 (Expand_N_Type_Conversion): Test for the case of renamings of access
7909 parameters when deciding whether to apply a run-time accessibility
7911 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
7912 aggregate code before allocator, and ahead of declaration for
7913 temporary, to prevent access before elaboration when the allocator is
7914 an actual for an access parameter.
7915 (Expand_N_Type_Conversion): On an access type conversion involving an
7916 access parameter, do not apply an accessibility check when the
7917 operand's original node was an attribute other than 'Access. We now
7918 create access conversions for the expansion of 'Unchecked_Access and
7919 'Unrestricted_Access in certain cases and clearly accessibility should
7920 not be checked for those.
7922 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
7923 includes a type conversion of a packed component that has been expanded,
7924 recover the original expression for the object, and use this expression
7925 in the post-call assignment statement, so that the assignment is made
7926 to the object and not to a back-end temporary.
7927 (Freeze_Subprogram): In case of primitives of tagged types not defined
7928 at the library level force generation of code to register the primitive
7929 in the dispatch table. In addition some code reorganization has been
7930 done to leave the implementation clear.
7931 (Expand_Call): When expanding an inherited implicit conversion,
7932 preserve the type of the inherited function after the intrinsic
7933 operation has been expanded.
7935 * exp_ch2.ads, exp_ch2.adb
7936 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
7937 of an entry formal appearing in an assignment statement does not assign
7939 (Expand_Current_Value): Instead of calling a routine to determine
7940 whether the prefix of an attribute reference should be optimized or
7941 not, prevent the optimization of such prefixes all together.
7943 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
7944 component whose prefix is known to be of an access type is an implicit
7945 dereference and does not assign to the prefix.
7947 2007-08-14 Ed Schonberg <schonberg@adacore.com>
7948 Robert Dewar <dewar@adacore.com>
7950 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
7951 itype is visited, make an entry into table to link associated node and

7954 (Array_Aggr_Subtype): Associate each itype created for an index type to
7955 the corresponding range construct, and not to the aggregate itself. to
7956 maintain a one-to-one correspondence between itype and its associated
7957 node, to prevent errors when complex expression is copied.
7958 Fix mishandling of multiple levels of parens
7960 * sem_aggr.adb: Create a limited view of an incomplete type, to make
7961 treatment of limited views uniform for all visible declarations in a
7962 limited_withed package.
7963 (New_Copy_Tree): If hash table is being used and itype is visited,
7964 make an entry into table to link associated node and new itype.
7965 (Resolve_Record_Aggregate): Do not add an others box association for a
7966 discriminated record component that has only discriminants, when there
7967 is a box association for the component itself.
7969 * par-ch4.adb: Fix mishandling of multiple levels of parens
7971 2007-08-14 Robert Dewar <dewar@adacore.com>

8004 Javier Miranda <miranda@adacore.com>
8005 Gary Dismukes <dismukes@adacore.com>
8007 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,

8012 attribute with constants.
8013 (Write_Field26_Name): Handle attribute Related_Interface in constants.
8014 Warn on duplicate pragma Preelaborable_Initialialization
8016 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
8017 generation of a freezing node to ensure proper management of null
8018 excluding access types in the backend.
8019 (Create_Extra_Formals): Test base type of the formal when checking for
8020 the need to add an extra accessibility-level formal. Pass the entity E
8021 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
8022 originally being done in a couple of cases), to ensure that the
8023 Extra_Formals list gets set on the entity E when the first entity is
8025 (Conforming_Types): Add missing calls to Base_Type to the code that
8026 handles anonymous access types. This is required to handle the
8027 general case because Process_Formals builds internal subtype entities
8028 to handle null-excluding access types.
8029 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
8030 functions that need it, even when not marked Requires_Overriding.
8031 Improve warnings for in out parameters
8032 (Analyze_Function_Return): Warn for disallowed null return

8034 Ensure consistent use of # in error messages
8035 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
8036 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
8037 the implicit conversion of the expression done for anonymous access
8038 types. This is required to generate the code of the null excluding
8039 check (if required).
8041 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
8042 A formal parameter is never publicly referenceable outside of its body.

8044 statement, use the same warning circuitry as for subprogram formal

8061 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
8062 (Expand_N_Attribute_Reference): Further unify the handling of the
8063 three forms of access attributes, using common code now for all three
8064 cases. Add a test for the case of applying an access attribute to
8065 an explicit dereference when the context is an access-to-interface
8066 type. In that case we need to apply the conversion to the prefix
8067 of the explicit dereference rather than the prefix of the attribute.
8068 (Attribute_Version, UET_Address): Set entity as internal to ensure
8069 proper dg output of implicit importation.
8070 (Expand_Access_To_Type): Removed.
8071 (Expand_N_Attribute_Reference): Merge the code from the three cases
8072 of access attributes, since the processing is largely identical for
8073 these cases. The substantive fix here is to process the case of a
8074 type name prefix (current instance case) before handling the case
8075 of interface prefixes.

8080 Robert Dewar <dewar@adacore.com>
8082 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
8083 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
8084 type that is an anonymous access to controlled object, establish
8085 an associated finalization chain to avoid corrupting the global
8086 finalization list when a dynamically allocated object designated
8087 by such a component is deallocated.
8088 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
8089 functions that need it, even when not marked Requires_Overriding.

8095 Suppress_Initialization pragma for a derived type.
8096 (Is_Variable_Size_Record): New subprogram.
8097 (Build_Offset_To_Top_Functions): New implementation that simplifies the

8109 (Freeze_Array_Type): Generate init proc for packed array if either
8110 Initialize or Normalize_Scalars is set.
8111 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
8112 constructing the new profile, copy the null_exclusion indicator for each
8113 parameter, to ensure full conformance of the new body with the spec.
8115 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
8116 Create wrappers for constructor functions that need it, even when not
8117 marked Requires_Overriding.

8160 type. In addition perform the following code cleanup: remove formal
8161 Thunk_Alias which is no longer required, cleanup evaluation of the
8162 the controlling type, and update the documentation.
8163 Replace occurrence of Default_Prim_Op_Count by

8170 construction of statically allocated dispatch tables.
8171 (Make_DT): In case of library-level tagged types export the declaration
8172 of the primary tag. Remove generation of tags (now done by Make_Tags).
8173 Additional modifications to handle non-static generation of dispatch
8174 tables. Take care of building tables for asynchronous interface types
8175 (Make_Tags): New subprogram that generates the entities associated with
8176 the primary and secondary tags of Typ and fills the contents of Access_
8177 Disp_Table. In case of library-level tagged types imports the forward
8178 declaration of the primary tag that will be declared later by Make_DT.
8179 (Expand_Interface_Conversion): In case of access types to interfaces
8180 replace an itype declaration by an explicit type declaration to avoid
8181 problems associated with the scope of such itype in transient blocks.

8184 Ed Schonberg <schonberg@adacore.com>
8185 Javier Miranda <miranda@adacore.com>
8187 * exp_util.ads, exp_util.adb:
8188 This patch replaces a number of occurrences of explicit tests for N_Null
8189 with calls to Known_Null. This improves tracking of null values, since
8190 Known_Null also catches null constants, and variables currently known to
8191 be null, so we get better tracking.
8192 (Ensure_Defined): create an itype reference only in the scope of the
8194 (Side_Effect_Free): A selected component of an access type that
8195 denotes a component with a rep clause must be treated as not
8196 side-effect free, because if it is part of a linked structure its
8197 value may be affected by a renaming.
8198 (Expand_Subtype_From_Expr): For limited objects initialized with build
8199 in place function calls, do nothing; otherwise we prematurely introduce
8200 an N_Reference node in the expression initializing the object, which
8201 breaks the circuitry that detects and adds the additional arguments to
8202 the called function. Bug found working in the new patch for statically
8203 allocated dispatch tables.
8204 (Is_Library_Level_Tagged_Type): New subprogram.
8205 (Remove_Side_Effects): If the expression of an elementary type is an
8206 operator treat as a function call.
8207 (Make_Literal_Range): If the index type of the array is not integer, use
8208 attributes properly to compute the constraint on the resulting aggregate
8211 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
8212 class-wide type whose base type is an incomplete private type, leave
8213 class-wide type unfrozen so that freeze nodes can be generated
8214 properly at a later point.
8215 (Freeze_Entity, array case): Handle case of pragma Pack and component
8216 size attributre clause for same array.

8737 Fix comments in bindgen regarding consistency checks done in Bcheck:
8738 the checks are made across units within a partition, not across several
8740 Fix generation of C binder file for VxWorks.
8742 * lib.ads, lib.adb (Generic_Separately_Compiled): Rename to

8865 operations in Derive_Subprograms.
8866 (Collect_Previous_Instances): new procedure within of
8867 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
8868 unit being loaded, to ensure that the generation of global symbols is
8869 consistent in different compilation modes.
8870 (Is_Tagged_Ancestor): New function testing the ancestor relation that
8871 takes progenitor types into account.
8872 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
8873 traversing over the primitives of the formal and actual types to locate
8874 any abstract subprograms of the actual type that correspond to a
8875 nonabstract subprogram of the formal type's ancestor type(s), and issue
8876 an error if such is found.
8877 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
8878 Instantiate_Package_Body, Instantiate_Subprogram_Body):
8879 Remove bogus guard around calls to Inherit_Context.
8880 (Reset_Entity): If the entity is the selector of a selected component

8884 a predefined or internal unit.
8886 2007-08-14 Ed Schonberg <schonberg@adacore.com>

8889 parameter to determine whether operation applies to the prefix.
8890 (Complete_Object_Operation): If actual has an access type and
8891 controlling formal is not an in_parameter, reject the actual if it is
8892 an access_to_constant type.
8893 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
8894 type, the candidate operations are found in the scope of declaration of
8895 the type, because the type has no primitive subprograms.
8896 (Analyze_Selected_Component): If prefix is class-wide, and root type is
8897 a private extension, only examine visible components before trying to
8898 analyze as a prefixed call.
8899 Change Entity_List to Type_To_Use, for better readability.
8900 (Has_Fixed_Op): Use base type when checking whether the type of an
8901 operator has a user-defined multiplication/division
8902 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
8903 user-defined operators are available for fixed-point types.

8908 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
8909 formal At_Any_Place indicating, when True, that we want to test for
8910 availability of the stream attribute at any place (as opposed to the
8911 current visibility context only).
8912 (Missing_Read_Write_Attributes): A stream attribute is missing for the
8913 purpose of enforcing E.2.2(8) only if it is not available at any place.
8914 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
8915 when checking the legality of an extension aggregate in a preelaborable
8916 package. Treat the literal null as a valid default expression in a
8917 component declaration for a type with preelaborable initialization.
8918 A limited interface is a legal progenitor for the designated type of a
8919 remote access to class-wide type.

8933 views that are themselves incomplete types.
8934 Handle interfaces visible through limited-with clauses.
8935 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
8936 subprogram generic actual for which we have generated a renaming.
8937 Warn when the renaming introduces a homonym of
8938 the renamed entity, and the renamed entity is directly visible.

8943 * sem_res.adb (Resolve_Allocator): Propagate any coextensions that
8944 appear in the subtree to the current allocator if it is not a static
8946 (Resolve_Allocator): Perform cleanup if resolution has determined that
8947 the allocator is not a coextension.
8948 (Resolve): Skip an interpretation hidden by an abstract operator only
8949 when the type of the interpretation matches that of the context.
8950 (Resolve): When looping through all possible interpretations of a node,
8951 do not consider those that are hidden by abstract operators.
8952 (Resolve_Actuals): When verifying that an access to class-wide object
8953 is an actual for a controlling formal, ignore anonymous access to
8954 subprograms whose return type is an access to class_wide type.
8955 (Resolve_Slice): If the prefix of the slice is a selected component
8956 whose type depends on discriminants, build its actual subtype before
8957 applying range checks on the bounds of the slice.
8958 (Valid_Conversion): In an instance or inlined body, compare root types,
8959 to prevent anomalies between private and public views.
8960 (Resolve): Improve error message for ambiguous fixed multiplication
8961 expressions that involve universal_fixed multiplying operations.

8966 * exp_ch9.adb (Build_Protected_Entry): Propagate the original source
8967 location to allow the correct generation of errors in case of
8968 restrictions applied to the expanded code.
8969 (Expand_Entry_Barrier): Remove all generated renamings for a barrier
8970 function if the condition does not reference them.
8971 (Expand_Entry_Body_Declarations): Mark the index constant as having a

8978 typecode parameters for a union (in a variant record), remove
8979 extraneous layer of Any wrapping for member label.
8980 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
8981 elabration statements, register the package with the name server
8982 at the beginning, not at the end, of the elaboration statements so
8983 that they can create remote access to subprogram values that designate
8984 remote subprograms from the package.
8986 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
8988 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
8989 values to compute the number of seconds since the Unix Epoc in order to
8990 account for Daylight Savings Time. Perform special processing for dates
8991 that are earlier than the Unix Epoc to obtain a negative number.

10113 bounds of the slice to construct the required constraint checks.
10114 Improve NOT NULL error messages
10115 (Apply_Constraint_Check): If the context is a null-excluding access
10116 type, diagnose properly the literal null.

10132 Arnaud Charlet <charlet@adacore.com>
10134 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
10135 applicable to types that have the With_Type flag set. Returns the
10136 non-limited view of the type, if available, otherwise the type itself.
10137 For class-wide types, there is no direct link in the tree, so we have
10138 to retrieve the class-wide type of the non-limited view of the Etype.
10139 New attributes Static_Initialization and Static_Elaboration_Desired.
10140 Remove the pragma Thread_Body, and the associated flag
10141 Is_Thread_Body in entities, and all related code.

10154 (Original_Access_Type): Remove, not needed.
10155 (Root_Type): Handle properly subtypes of class-wide-types.
10158 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
10159 class-wide types visible through limited-with clauses.
10160 (Try_Primitive_Operation): When examining all primitive operations of a
10161 tagged type, do not consider subprograms labeled as hidden unless they
10162 belong to a private generic type with a tagged parent.
10163 (Try_Object_Operation): Extensive rewriting, to handle properly various
10164 overloading cases, when several ancestors may have class-wide operations
10165 that are possible candidates, and when the overloaded functions return
10166 array types and have defaulted parameters so that the call may be
10167 interpreted as an indexing.
10168 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
10169 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
10170 successive actuals before analyzing the call itself.
10171 (Try_Primitive_Operation): A primitive operation is compatible with the
10172 prefix if the prefix has a synchronized type and the type of the formal
10173 is its corresponding record, as can be the case when the primitive
10174 operation is declared outside of the body of the type.
10175 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
10176 perform homonym traversal, looking for class-wide operation matches
10177 (formerly done in statements of Try_Class_Wide_Operation). Matches on
10178 access parameters are now restricted to anonymous access types.
10179 (Mark_Allocator): An allocator with a discriminant association parent is
10181 (Try_One_Prefix_Interpretation): If the type of the object is
10182 incomplete, as can be happen when it is a limited view obtained through
10183 a limited_with_clause, the selected component is not part of a prefixed
10185 (Complete_Object_Operation): Diagnose properly an object that is not
10186 aliased when the corresponding controlling formal is an access
10188 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
10189 ambiguous calls in prefixed notation, where two primitives differ only
10190 in that the controlling argument of one is an access parameter.
10192 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
10193 whether a function that returns an unconstrained type can be inlined.
10194 (Process_Formals): Diagnose properly the illegal use of an incomplete
10195 type in the profile of an access_to_subprogram declaration.
10196 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
10197 operations are attached to the corresponding record.
10198 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
10199 When processing a primitive of a concurrent type which implements an
10200 interface change the type of all controlling formals to that of the
10201 corresponding record type.
10202 (Check_Synchronized_Overriding): Relax the conditional logic when trying
10203 to determine the tagged type to which a primitive belongs.
10204 (Check_Conventions): Capture condition to ignore a primitive operation
10205 (which is shared between the loop in Check_Conventions and the one in
10206 Check_Convention) in a new local function Skip_Check.
10207 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
10208 confusion with Check_Conventions' own Prim_Op local variable.
10209 (Create_Extra_Formals): Test for a tagged result type rather than a
10210 controlling result when determining whether to add a BIP_Alloc_Form
10211 formal and a BIP_Final_List formal to the function.
10212 (Check_Conformance); For parameters that are anonymous access types,
10213 subtype conformance requires that the not null and the constant
10214 indicators must match
10215 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
10216 to retrieve the appropriate type when processing a concurrent type
10217 declared within a generic. Minor comment reformatting. Change invocation
10218 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
10220 (Analyze_Subprogram_Body): If the return type of a function is an
10221 anonymous access to the limited view of a class-wide type, and the
10222 non-limited view of the type is available, update the type of the
10223 function so that code can be generated.
10224 (Process_Formals): In case of access-subtype itype whose designated
10225 type is also an itype (situation that happens now with access to
10226 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
10227 attribute to avoid backend problems.
10228 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
10229 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
10230 anonymous types' designated types are same before testing
10231 Subtypes_Statically_Match.
10232 (Create_Extra_Formals): Test for a named access parameter that is a
10233 controlling formal as an additional condition for adding an
10234 accessibility level formal. This can occur in the subp type created for
10235 dispatching calls in Expand_Dispatching_Call, and allows calling
10236 Create_Extra_Formals from that procedure rather than special-casing the
10237 extra formals there.
10238 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
10239 when the function has a controlling result.
10240 (Check_Returns): Add much more knowledge of the optimization of local
10241 raise statements to gotos, to retain proper warnings in this case.
10242 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
10243 nodes when looking for last statement.
10245 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
10246 class-wide types visible through limited with clauses.
10247 (Add_One_Interp): If the operands are anonymous access types, the
10248 predefined operator on universal_access is immediately visibles
10249 (Find_Unique_Type): Handle anonymous access to subprogram types just as
10250 other anonymous access types.
10251 (Disambiguate): Take into account CIL convention.
10252 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
10254 2007-06-06 Robert Dewar <dewar@adacore.com>

10269 Hristian Kirtchev <kirtchev@adacore.com>
10271 * exp_aggr.ads, exp_aggr.adb:
10272 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
10273 in extension aggregates.
10274 (Flatten): Other conditions being met, an aggregate is static if the
10275 low bound given by component associations is different from the low
10276 bound of the base index type.
10277 (Packed_Array_Aggregate_Handled): If the component type is itself a
10278 packed array or record, the front-end must expand into assignments.
10279 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
10280 Init_Pr, instead of Ancestor_Is_Expression.
10281 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
10282 coextension chain root, either generate a list controller or use the
10283 already existing one.
10284 (Static_Array_Aggregate): New procedure to construct a positional
10285 aggregate that can be handled by the backend, when all bounds and
10286 components are compile-time known constants.
10287 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
10288 types covering interface types into assignments.
10289 (Replace_Type): move to Build_Record_Aggr_Code.
10290 (Expand_Record_Aggr_Code): if the target of the aggregate is an
10291 interface type, convert to the definite type of the aggregate itself,
10292 so that needed components are visible.
10293 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
10294 components and the context is an extended return statement do not
10295 create a transient block for it, to prevent premature finalization
10296 before the return is executed.
10297 (Gen_Assign): Do not generate a call to deep adjust routine if the
10298 component type is itself an array of controlled (sub)-components
10299 initialized with an inner aggregate.
10300 (Component_Check): New name for Static_Check. This name is now more
10301 appropriate, and documentation is added which was missing.
10302 (Component_Check): Add test for bit aligned component value
10303 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
10304 Tagged_Comps, name is more appropriate given added function below.
10305 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

10309 Robert Dewar <dewar@adacore.com>
10311 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
10312 Terminated: Add unchecked type conversion from System.Address to
10313 System.Tasking.Task_Id when calling the predefined primitive
10315 Disable new Ada 05 accessibility check for JVM.NET targets, which
10316 cannot be implemented in a practical way.
10317 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
10318 the sources always references the tag of the actual object. Therefore,
10319 if 'Tag is applied in the sources to class-wide interface objects we
10320 generate code that displaces "this" to reference the base of the object.
10321 (Expand_N_Attribute_Reference, case Size): Return specified size if
10322 known to front end.
10323 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
10324 has code that displaces the pointer of the object to manage interface
10325 types. However this code must not be executed when the prefix is a
10326 subprogram. This bug caused the wrong expansion of the internally
10327 generated assignment that fills the dispatch table when the primitive
10328 is a function returning a class-wide interface type.
10329 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
10330 Set_Attribute_Name for Name_Unaligned_Valid.

10335 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
10336 If the initialization is the equivalent aggregate of the initialization
10337 procedure of the type, do not remove it.
10338 (Expand_N_Attribute_Definition_Clause): Exclude access variables
10339 initialized to null from having their expression reset to empty and
10340 note this exception in the comment.

10348 Add "with" and "use" clauses for Sem_Attr.
10349 (Expand_Current_Value): Do not replace occurences of attribute
10350 references where the prefix must be a simple name.
10352 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
10353 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
10354 Attribute_Requires_Simple_Name_Prefix.
10355 (Name_Modifies_Prefix): Body of new function.
10356 (Requires_Simple_Name_Prefix): Body of new function.
10357 (Resolve_Attribute, case Access): Improve error message for case of
10358 mismatched conventions.
10359 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
10361 (Analyze_Attribute, case 'Access): If the type of the prefix is a
10362 constrained subtype for a nominal unconstrained type, use its base type
10363 to check for conformance with the context.
10364 (Resolve_Attribute): Remove test of the access type being associated
10365 with a return statement from condition for performing accessibility
10366 checks on access attributes, since this case is now captured by
10367 Is_Local_Anonymous_Access.
10368 (Analyze_Access_Attribute): Set Address_Taken on entity
10369 (Analyze_Attribute, case Address): Set Address_Taken on entity
10370 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
10371 validating an access attribute whose prefix is a current instance.
10372 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
10373 applied to dispatching operations, if freezing is required then we set
10374 the attribute Has_Delayed_Freeze in the prefix's entity.
10375 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
10376 current scope if access of local subprogram taken
10377 (Analyze_Access_Attribute): Check legality of self-reference even if the
10378 expression comes from source, as when a single component association in
10379 an aggregate has a box association.
10380 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
10381 the prefix if it is a protected operation and the attribute is
10382 Unrestricted_Access.
10383 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
10384 reference to the base type of the context, to force a constraint check
10385 when the context is an access subtype with an explicit constraint.
10386 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
10387 node is rewritten as an interface conversion. leave unanalyzed after
10388 resolution, to ensure that type checking against the context will take

10395 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
10396 wrapper when the full view of the controlling type of an inherited
10397 function that dispatches on result implements interfaces.
10398 (Expand_N_Object_Declaration): In cases where the type of the
10399 declaration is anonymous access, create finalization list for it.
10400 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
10401 if the object has no explicit initialization, to match description of
10402 functionality of pragam Persistent_BSS.
10403 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
10404 new function to build static aggregates, to replace initialization call
10405 when static initialization is desired.
10406 (Freeze_Type): Generate a list controller for an access type whenever
10407 its designated type has controlled anonymous access discriminants.
10408 (Build_Equivalent_Aggregate): New procedure to compute a static
10409 aggregate to be used as default initialization for composite types,
10410 instead of a generating a call to the initialization procedure for the
10412 (Build_Initialization_Call): When available, replace a call to the
10413 initialization procedure with a copy of the equivalent static aggregate
10415 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
10416 declarations for objects of a class-wide interface type, rather than
10417 just identifiers, to prevent visibility problems.
10418 (Expand_N_Object_Declaration): When expanding the declaration for an
10419 object of a class-wide interface type, preserve the homonym chain of
10420 the original entity before exchanging it with that of the generated
10421 renaming declaration.
10422 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
10423 active, because there is no way to handle the exception.
10424 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
10425 to do a minimum decoration of the Access_Disp_Table list.
10426 (Expand_Record_Controller): Avoid the addition of the controller between
10427 the component containing the tag of a secondary dispatch table and its
10428 adjacent component that stores the offset to the base of the object.
10429 This latter component is only generated when the parent type has
10430 discriminants ---documented in Add_Interface_Tag_Components).
10431 (Apply_Array_Size_Check): Removed, no longer needed.
10432 (Expand_N_Full_Type_Declaration): If the type has anonymous access
10433 components, create a Master_Entity for it only if it contains tasks.
10434 (Build_Init_Procedure): Suppress the tag assignment compiling under
10436 (Freeze_Record_Type): Remove code associated with creation of dispatch
10438 (Init_Secondary_Tags): Update type of actuals when generating calls to
10439 Ada.Tags.Set_Offset_To_Top
10440 (Stream_Operation_OK): Disable use of streams compiling under no
10442 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
10443 if Has_Init_Expression set.
10444 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
10445 Register_Primitive, which provides the same functionality.
10446 (Requires_Init_Proc): Return false in case of interface types.
10447 (Add_Secondary_Tables): Use the new attribute Related_Interface to
10449 (Predefined_Primitive_Freeze): Do not assume that an internal entity
10450 is always associated with a predefined primitive because the internal
10451 entities associated with interface types are not predefined primitives.
10452 Therefore, the call to Is_Internal is replaced by a call to the
10453 function Is_Predefined_Dispatching_Operation.
10454 (Make_Eq_If): When generating the list of comparisons for the
10455 components of a given variant, omit the controller component that is
10456 present if the variant has controlled components.

10462 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
10463 handle the creation of finalization lists and calls for nested
10464 coextensions when the root of the chains is part of a return statement.
10465 (Inside_A_Return_Statement): New function inside Complete_Coextension_
10467 (Expand_Record_Equality): Skip components that are interface types.
10468 (Displace_Allocator_Pointer): Add missing support for interface subtypes
10469 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
10470 with Rewrite_Coextension. Change the condition for detecting coextension
10472 (Is_Local_Access_Discriminant): Removed.
10473 (Rewrite_Coextension): New routine which rewrites a static coextension
10474 as a temporary and uses its unrestricted access in the construction of
10476 (Complete_Coextension_Finalization): New routine. Generate finalization
10477 attachment calls to all delayed coextensions.
10478 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
10479 the allocator is not a coextension itself and has delayed coextensions.
10480 If the current allocator is controlled, but also a coextension, delay
10481 the generation of the finalization attachment call.
10482 Rename local variable "Node" to "Nod" in order to avoid confusion with
10484 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
10485 limited types that are not inherently limited. Such an allocator is
10486 illegal, but is generated by the expander for a return statement, to
10487 copy the result onto the secondary stack. This is the only case where a
10488 limited object can be copied. Generate code to displace the pointer
10489 to the object if the qualified expression is a class-wide interface
10490 object. Such displacement was missing and hence the copy of the object
10492 (Apply_Accessibility_Check): Handle allocated objects initialized in
10494 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
10495 and Expand_Allocator_Expression. Allocating class-wide interface objects
10496 this routine displaces the pointer to the allocated object to reference
10497 the component referencing the corresponding secondary dispatch table.
10498 Expand_Allocator_Expression): Add missing support to allocate class-wide
10499 interface objects initialized with a qualified expression.
10500 (Get_Allocator_Final_List): Test for an anonymous access type that is a
10501 function result type, and use the finalization list associated with the
10502 function scope in that case (such an anonymous type should not be
10503 treated like an access parameter's type).

10506 Gary Dismukes <dismukes@adacore.com>
10507 Javier Miranda <miranda@adacore.com>
10509 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
10510 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
10511 required exception handler.
10512 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
10513 properly the case of a function whose return type is a limited
10514 class-wide interface type. Modify the code of the accessibility
10515 check to handle class-wide interface objects. In this case we need to
10516 displace "this" to reference the primary dispatch table to get access
10517 to the TSD of the object (to evaluate its accessibility level).
10518 (Expand_N_Extended_Return_Statement): Test for a tagged result type
10519 rather than a controlling result as one of the conditions for
10520 generating tests of the implicit BIP_Alloc_Form formal. The
10521 initialization assignment is also handled according to whether the
10522 result is tagged instead of controlling.
10523 In the case where the init assignment is inserted in the "then" part of
10524 the allocation conditional, rewrite the target to be a dereference of
10525 the implicit BIP_Object_Access formal.
10526 If the returned value is unconstrained and created on the secondary
10527 stack, mark the enclosing block and function so that the secondary
10528 stack is not reclaimed on return.
10529 Treat returns from functions with controlling results similarly to
10530 returns from functions with unconstrained result subtypes.
10531 If the object returned is unconstrained, and an allocator must be
10532 created for it, analyze the allocator once the block for the extended
10533 return is installed, to ensure that finalizable components
10534 of the expression use the proper finalization list. Guard the call to
10535 Move_Final_List with a check that there is something to finalize.
10536 (Make_Tag_Ctrl_Assignment): Use "old" handling
10537 of controlled type assignment for virtual machines, since new code uses
10538 unsupported features (such as direct access to bytes in memory).

10541 Ed Schonberg <schonberg@adacore.com>
10543 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
10544 accessibility actual, check for the case of an aliased object that has
10545 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
10546 we fall into processing for the attribute rather than the name of the
10548 (Expand_Inline_Call): If an actual is a literal, and the corresponding
10549 formal has its address taken in the body, create a temporary to capture
10550 value. If the return type is a limited interface, do not treat the
10551 return value as Controlled.
10552 (Is_In_Place_Function): If the return type is a limited interface,
10553 treat as returning in place. The actual returned object may not always
10554 be limited, but the caller has to assume that it is returned in place.
10555 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
10556 context of an allocator, use the correct finalization chain (that is,
10557 the chain belonging to the access type, rather than the chain belonging
10558 to the current scope).
10559 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
10560 result type rather than a controlling result as a precondition for
10561 adding an allocation form actual to a build-in-place call.
10562 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
10563 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
10564 primitive in the dispatch tables. This work is now done by Make_DT when
10565 the type is frozen.
10566 (Register_Predefined_DT_Entry): Removed.
10567 (Add_Return): If end label is not present, use sloc of last statement
10568 for generated return statement in procedure, for better gdb behavior
10570 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
10571 object address nodes to ensure proper processing by routines like
10573 (Expand_Call): Fix generation of validity check for parameter
10574 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
10575 the allocation form parameter if the result subtype is constrained,
10576 except when the function has a controlling result.
10577 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
10578 rather than Is_Controlled and Has_Controlled_Component, since we want to
10579 include class-wide result types in this treatment. Also test for a
10580 controlling result, since that also requires passing a finalization
10582 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
10583 even when the result subtype is constrained, to handle calls involving
10584 controlling results.
10585 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
10586 is now called even when the result subtype is constrained, to handle
10587 calls involving controlling results.
10588 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
10589 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
10590 now performs the test).
10591 (Make_Build_In_Place_Call_In_Object_Declaration):
10592 Add_Alloc_Form_Actual_* is now called even when the result subtype is
10593 constrained, to handle calls involving controlling results.
10594 (Add_Return): Accomodate rewritten pattern from local raise to goto
10595 transformation, so that we still recognize an transfer statement
10596 and do the right thing here in that case.
10597 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
10598 and end of subprogram code.
10599 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
10600 support for primitives that are functions (without formals) with a
10601 controlling result.
10602 (Inherited_From_Formal): If the actual subtype has not generic parent
10603 type, it is not an actual for a formal derived type, and there is no
10604 operation to inherit from the formal.

10607 Thomas Quinot <quinot@adacore.com>
10609 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
10610 inserted cleanup code appropriately for GDB use.
10611 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
10612 exception handler for Deep_Adjust or Deep_Finalize.
10613 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
10614 Raise_From_Controlled_Operation is available, use a call to that
10615 subprogram instead of a plain "raise Program_Error" node to raise
10616 Program_Error if an exception is propagated from an Adjust or Finalize
10618 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
10619 appears in the optional statement list of a triggering alternative, the
10620 scope actions can be inserted directly there, and not in the list that
10621 includes the asynchronous select itself.

10628 generated exception handler appropriately when debugging generated code.
10629 Deal properly with No_Exception_Propagation restriction mode.
10630 (Expand_N_Abort_Statement): Add an unchecked type conversion from
10631 System.Address to System.Tasking.Task_Id when processing the result of
10632 the predefined primitive _disp_get_task_id.
10633 (Expand_N_Asynchronous_Select): Clarify comment.
10634 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
10635 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
10636 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
10637 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
10638 privals and for generated call to Complete_Entry_Body, for better gdb

10641 for protected functions whose return type is an anonymous access to
10643 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
10645 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
10646 point when the local-raise-to-goto transformation has taken place.

10649 Nicolas Setton <setton@adacore.com>
10651 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
10652 functionality when the backend is generating code.
10653 Otherwise any serious error
10654 reported by the backend calling the frontend routine Error_Msg
10655 changes the Compilation_Mode to Check_Semantics, disables the
10656 functionality of this routine and causes the generation of
10657 spureous additional errors.
10659 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
10660 debugging information now generated by the compiler for fat-pointer
10662 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
10664 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
10666 2007-06-06 Thomas Quinot <quinot@adacore.com>
10668 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
10669 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
10670 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
10671 For a remote call to a function with a classwide return type, apply an
10672 E.4(18) check to the returned value.
10673 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
10674 stream attributes of the designated type of an RACW, as they are not
10675 dispatching primitive operations.
10677 2007-06-06 Geert Bosch <bosch@adacore.com>
10679 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a

10691 attribute compiling package Ada.Tags under No_Run_Time_Mode.
10693 2007-06-06 Javier Miranda <miranda@adacore.com>
10695 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
10696 deallocation of class-wide interface objects.
10697 (Expand_Dispatching_Constructor_Call): Take into account that if the
10698 result of the dispatching constructor is an interface type, the
10699 function returns a class-wide interface type; otherwise the returned
10700 object would be actual. The frontend previously accepted returning
10701 interface types because Expand_Interface_Actuals silently performed
10702 the management of the returned type "as if" it were a class-wide
10704 (Expand_Dispatching_Constructor_Call): Replace call to
10705 Make_DT_Access_Action by direct call to Make_Function_Call.

10708 Ed Schonberg <schonberg@adacore.com>
10710 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
10711 compute masking constant, since we now set Esize properly to the
10713 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
10714 to match the alignment.
10715 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
10716 packed arrays of 8 bits or less.
10718 * freeze.adb (Freeze_Entity): When freezing the formals of a
10719 subprogram, freeze the designated type of a parameter of an access type
10720 only if it is an access parameter.
10721 Increase size of C convention enumeration object
10722 (Freeze_Entity, array type case): Make sure Esize value is properly
10723 adjusted for the alignment if it is known.
10724 (Freeze_Entity, array type case): When checking bit packed arrays for
10725 the size being incorrect, check RM_Size, not Esize.
10726 (Freeze_Record_Type): Check for bad discriminated record convention
10727 (In_Exp_Body): Return true if the body is generated for a subprogram
10728 renaming, either an attribute renaming or a renaming as body.
10729 (Check_Itype): If the designated type of an anonymous access component
10730 is a non-protected subprogram type, indicate that it is frozen, to
10731 prevent out-of-scope freeze node at some subsequent call.
10732 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
10733 only if the subprogram is neither imported nor exported, as well as the
10734 NCA descriptor class if the subprogram is exported.

10743 initialization call generated for it.
10744 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
10747 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
10748 Static_Elaboration_Desired.
10749 Remove pragma Thread_Body.
10750 Implement a new pragma No_Body
10751 Removes the Explicit_Overriding pragma
10752 Remove Optional_Overriding pragma
10753 (Prag): Deal with Universal_Aliasing.
10754 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
10755 Pragma_CIL_Constructor): New names.
10757 * sem_cat.adb (Validate_Object_Declaration): An initialization that
10758 uses the equivalent aggregate of a type must be treated as an implicit

10761 has none of the other categories.
10762 (Process_Import_Or_Interface_Pragma): Report an error for an attempt

11325 associated with dispatch tables is known at compile time.
11326 (Get_Value): If an association in a record aggregate has a box
11327 association, and the corresponding record component has a default
11328 expression, always copy the default expression, even when the

12767 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
12768 when -gnatg is not specified.
12769 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
12770 there is no need to generate always a record_definition_node in case
12771 of synchronized interface types.

12798 (Convert_Aggr_In_Allocator): If the allocator is for an access
12799 discriminant and the type is controlled. do not place on a finalization
12800 list at this point. The proper list will be determined from the

12820 parameter of the containing subprogram.
12821 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
12822 under No_Dispatching_Calls restriction. During the semantic analysis
12823 we already notified such violation.

12843 because we now expand code that has a higher level of abstraction.
12844 The TSD has a discriminant containing the Inheritance Depth Level,
12845 value that is used in the membership test but also to fix the size
12846 of the table of ancestors.
12847 (Expand_Interface_Conversion): Insert function body at the closest place

13000 instantiating a RCI_Locator package.
13001 (Build_From_Any_Function): To compute the High bound for an
13002 unconstrained array actual, we add the Low bound with the length.
13003 Thus we must convert the low bound and the length to an appropriate
13004 type before doing the sum.
13005 (Build_Subprogram_Receiving_Stubs, PolyORB):
13006 * Retrieve the extra formals parameters at the
13007 end of the parameter stream.
13008 * Use Move_Any_Value to write back out parameters
13009 after executing the request as it is more efficient
13010 than Copy_Any_Value.
13011 * Build the any containing Extra Formals with the
13012 appropriate typecode.
13013 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
13014 empty Component_List.
13015 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
13016 the tree the declaration for an object that serves as actual parameter
13017 in server-side stubs.
13018 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13019 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13020 Use Build_Actual_Object_Declaration to prepare the actuals.

13022 Extra Constrained Parameters.
13023 (Build_General_Calling_Stubs): Set the parameter type to boolean for
13024 Extra Constrained parameters.
13025 (Build_To_Any_Function, Build_From_Any_Function,
13026 Built_TypeCode_Function): When Typ is implicit, call the correct
13027 function with the first not implicit parent type.
13028 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
13029 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
13030 typecode from the Etype. Therefore we retrieve the correct typecode
13031 with a call to Get_Any_Type.
13032 (Copy_Specification): Do controlling formal type substitution based on
13033 Is_Controlling_Formal flag, instead of caller-provided object type.
13034 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
13035 a RACW primitive operation, we might get a subprogram declaration for an
13036 ancestor of the RACW designated type (not for the designated type
13037 itself), in the case where this operation is inherited. In this case we
13038 have no easy means of determining the original tagged type for which
13039 the primitive was declared, so instead we now rely on
13040 Copy_Specification to use the Is_Controlling_Formal flag to determine
13041 which formals require type substitution.

13047 GNAT.Current_Exception are not allowed if pragma Restrictions
13048 (No_Exception_Propagation) is set and in any case make the associated
13049 handler unsuitable as a target for a local raise statement.
13050 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
13051 run-time subprogram CW_Membership by call to Build_CW_Membership.
13052 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
13053 by a function call, a temporary must be created before expanding the
13054 Constructor_Call itself, to prevent out-of-order elaboration in the
13055 back-end when stack checking is enabled..
13057 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13059 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
13060 result are the bounds of the left operand, not the right.
13062 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13065 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use
13066 discriminant defaults.

13077 box corresponds to a component of the type.
13078 (Resolve_Record_Aggregate): Split Is_Abstract flag into
13079 Is_Abstract_Subprogram and Is_Abstract_Type.

13188 This set of patch add support for the encoding form parameter.
13189 (S2WS): Improve implementation to handle cases where the filename is not

13241 implementation of floating point operations as native x86 targets.
13242 So the FPU should be initialized in the same way using finit. Fix
13243 floating point operations accuracy issues.

13472 Expand_Limited_With_Clause): Use a new copy of selector name in the
13473 call to Make_With_Clause. This fixes the tree structure for ASIS
13474 purposes. Nothing is changed in the compiler behaviour.
13475 (Process_Body_Clauses): Handle properly use clauses whose prefix is
13476 a package renaming.
13477 (Install_Limited_With_Clauses): Do not install non-limited view when it
13478 is still incomplete.
13480 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13481 Gary Dismukes <dismukes@adacore.com>
13483 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
13484 when capturing size information, instead of base type, which for a
13485 formal array type will be the unconstrained type.
13486 (Analyze_Formal_Object_Declaration): Add check for illegal default
13487 expressions for a formal in object of a limited type.
13488 (Instantiate_Object): Ditto.
13489 (Check_Formal_Package_Instance): Skip entities that are formal objects,
13490 because they were defaulted in the formal package and no check applies
13492 (Check_Formal_Package_Instance): Extend conformance check to other
13493 discrete types beyond Integer.
13494 (Process_Default): Copy directly the unmatched formal. A generic copy
13495 has already been performed in Analyze_Formal_Package.
13496 (Analyze_Associations): If a formal subprogram has no match, check for
13497 partial parametrization before looking for a default, to prevent
13499 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
13500 not set the instantiation environment before analyzing the actuals.
13501 Fixes regression on 8515-003 with implementation of AI-133.
13502 Set_Instance_Env checks whether the generic unit is a predefined
13503 unit, in which case the instance must be analyzed with the latest Ada
13504 mode. This setting must take place after analysis of the actuals,
13505 because the actuals must be analyzed and frozen in the Ada mode extant
13506 outside of the current instantiation.
13507 (Save_Env, Restore_Env): Preserve and restore the configuration
13508 parameters so that predefined units can be compiled in the proper Ada
13510 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
13511 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
13512 and Is_Abstract_Type.
13513 (Analyze_Formal_Package): For better error recovery, Add exception
13514 handler to catch Instantion_Error, which can be raised in
13515 Analyze_Associations
13517 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13518 Bob Duff <duff@adacore.com>
13519 Gary Dismukes <dismukes@adacore.com>
13521 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
13522 prefix type is a discriminated subtype of the type of the formal.
13523 (Analyze_Allocator): Collect all coextensions regardless of the context.
13524 Whether they can be allocated statically is determined in exp_ch4.
13525 (Analyze_Selected_Component): If the prefix is a limited view and the
13526 non-limited view is available, use the non-limited one.
13527 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
13528 therefore illegal), suggest a qualified expression rather than a type
13529 conversion, because a type conversion would be illegal in this context.
13530 (Anayze_Allocator): Trace recursively all nested allocators so that all
13531 coextensions are on the corresponding list for the root. Do no mark
13532 coextensions if the root allocator is within a declaration for a stack-
13533 allocated object, because the access discriminants will be allocated on
13535 (Analyze_Call): Remove restriction on calls to limited functions for the
13536 cases of generic actuals for formal objects, defaults for formal objects
13537 and defaults for record components.
13538 (Analyze_Allocator): Before analysis, chain coextensions on the proper
13539 element list. Their expansion is delayed until the enclosing allocator
13540 is processed and its finalization list constructed.
13541 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
13542 for an operation with the given name among the primitive operations of
13543 the corresponding record type.
13544 (Analyze_Selected_Component): If the prefix is a task type that
13545 implements an interface, and there is no entry with the given name,
13546 check whether there is another primitive operation (e.g. a function)
13548 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
13549 properly the indexing of a function call written in prefix form, where
13550 the function returns an array type, and all parameters of the function
13551 except the first have defaults.
13552 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
13553 the original operands, rather than relocating them, for efficiency and
13554 to work properly when an operand is overloaded.
13555 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
13556 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
13557 (Analyze_Selected_Component): If the prefix is a private extension, only
13558 scan the visible components, not those of the full view.
13559 (Try_Primitive_Operation): If the operation is a procedure, collect all
13560 possible interpretations, as for a function, because in the presence of
13561 classwide parameters several primitive operations of the type can match
13562 the given arguments.

13565 Robert Dewar <dewar@adacore.com>
13567 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
13568 tag-indeterminate call to an abstract function, when the left-hand side
13570 (Analyze_Loop_Statement): Improve detection of infinite loops
13572 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13573 Thomas Quinot <quinot@adacore.com>
13575 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
13576 out of Analyze_Package_Declaration, because processing must be applied
13577 to package bodies as well, for deferred constants completed by pragmas.
13578 (Analyze_Package_Declaration): When the package declaration being
13579 analyzed does not require an explicit body, call Check_Completion.
13580 (May_Need_Implicit_Body): An implicit body is required when a package
13581 spec contains the declaration of a remote access-to-classwide type.
13582 (Analyze_Package_Body): If the package contains RACWs, append the
13583 pending subprogram bodies generated by exp_dist at the end of the body.
13584 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
13585 Is_Abstract_Subprogram and Is_Abstract_Type.
13586 (Preserve_Full_Attributes): The full entity list is not an attribute
13587 that must be preserved from full to partial view.
13589 * sem_dist.adb (Add_RAS_Dereference_TSS):
13590 Change primitive name to _Call so it cannot clash with any legal
13591 identifier, and be special-cased in Check_Completion.
13592 Mark the full view of the designated type for the RACW associated with
13593 a RAS as Comes_From_Source to get proper view switching when installing
13594 private declarations.
13595 Provite a placeholder nested package body along with the nested spec
13596 to have a place for Append_RACW_Bodies to generate the calling stubs
13597 and stream attributes.
13599 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13600 Robert Dewar <dewar@adacore.com>
13602 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
13603 that is a limited view, check the non-limited view if available.
13604 (Undefined): Refine error message for missing with of Text_IO
13605 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
13606 to distinguish real missing with cases.
13607 Fix format of all missing with messages
13608 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
13609 renaming as body when renamed entity is abstract.
13611 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13612 Javier Miranda <miranda@adacore.com>
13614 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
13615 predicate recursive, to handle complex expressions on literals whose
13616 spurious ambiguity comes from the abstract interpretation of some
13618 (Interface_Present_In_Ancestor): Add support to concurrent record
13620 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
13621 Is_Abstract_Subprogram and Is_Abstract_Type.
13623 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13624 Javier Miranda <miranda@adacore.com>
13626 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
13627 dereference of a local object R created as a reference to another
13628 object O, use the access level of O.
13629 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
13630 rather than local Same_Formal_Type, to check whether protected operation
13631 overrides an inherited one.
13632 (Same_Formal_Type): New predicate, used when matching signatures of
13633 overriding synchronized operations, to handle the case when a formal
13634 has a type that is a generic actual.
13635 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
13636 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
13637 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
13638 syntactic ambiguities involving indexing of function calls that return
13640 (Abstract_Interface_List): New subprogram that returns the list of
13641 abstract interfaces associated with a concurrent type or a
13642 concurrent record type.
13643 (Interface_Present_In_Parent): New subprogram used to check if a
13644 given type or some of its parents implement a given interface.
13645 (Collect_Abstract_Interfaces): Add support for concurrent types
13646 with interface types.
13647 (Has_Abstract_Interfaces): Add support for concurrent types with
13649 (Is_Parent): New subprogram that determines whether E1 is a parent
13650 of E2. For a concurrent type its parent is the first element of its
13651 list of interface types; for other types this function provides the
13652 same result than Is_Ancestor.
13653 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
13654 (Collect_Synchronized_Interfaces): Removed because the subprogram
13655 Collect_Abstract_Interfaces provides this functionality.
13656 (Collect_Abstract_Interfaces): Minor update to give support to
13657 concurrent types and thus avoid undesired code duplication.
13658 (Get_Subprogram_Entity): Handle entry calls.
13659 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
13661 (Enter_Name): Do not give -gnatwh hiding warning for record component
13662 entities, they never result in hiding.

13671 New field Exception_Label added
13672 (Local_Raise_Statements): New field in N_Exception_Handler_Node
13673 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

13677 can be an E_Return_Statement.
13678 (Is_Coextension): New flag for allocators.

13697 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
13698 expression with a COMPOUND_EXPR including the call instead of emitting
13699 the call directly here.
13700 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
13701 high bound is constant and the slice is empty. Tidy.
13702 (tree_transform, case N_Op_Not): Handle properly the case where the
13703 operation applies to a private type whose full view is a modular type.
13704 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
13705 Address_Clause, use the associated Expression as the GNAT tree
13706 representing the choice value to ensure the corresponding GCC tree is
13707 of the proper kind.
13708 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
13709 instead of just the operands, as the base GCC stabilize_reference does.
13710 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
13711 requested; otherwise fail.
13712 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

13717 implementation of UI_Div.
13718 (UI_Div): Reimplement as a call to UI_Div_Rem.
13719 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
13720 remainder, avoiding the cost of a multiplication and a subtraction.
13721 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
13722 provides both quotient and remainder in a single computation.
13723 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
13724 functions for uint.
13725 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram

13746 (gnat_install_builtins): Adjust comments.
13747 (builtin_function): Set DECL_BUILTIN_CLASS and DECL_FUNCTION_CODE before

13972 (mainly static expression evaluation).
13973 Reword some continuation messages
13974 Add some \\ sequences to continuation messages
13975 (Resolve_Call): Refine infinite recursion case. The test has been

13991 Valid_Conversion, to incorporate accessibility checks for arrays of
13992 anonymous access types.
13993 (Valid_Conversion): For a conversion to a numeric type occurring in an
13994 instance or inlined body, no need to check that the operand type is
13995 numeric, since this has been checked during analysis of the template.

14584 assignments where the target subtype is unconstrained and the target
14585 object is a parameter or dereference (other aliased cases are known

14796 initialization of extension aggregates with abstract interfaces.
14797 (Build_Master_Renaming): Make public, for use by function declarations
14798 whose return type is an anonymous access type.
14799 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
14800 Insert_List_Before_And_Analyze after the generation of the specs
14801 associated with null procedures.
14802 (Expand_Tagged_Root): Update documentation in its specification.
14803 (Init_Secondary_Tags): Update documentation.
14804 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
14805 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
14806 then generate code to inherit the contents of the dispatch table
14807 directly from the ancestor.
14808 (Expand_Record_Controller): Insert controller component after tags of
14809 implemented interfaces.
14810 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
14811 create null procedure overridings when null procedures are inherited
14813 (Make_Null_Procedure_Specs): New procedure to generate null procedure
14814 declarations for overriding null primitives inherited from interfaces.
14815 (Is_Null_Interface_Procedure): New function in
14816 Make_Null_Procedure_Specs.
14817 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
14818 immediate ancestor of a tagged type is an abstract interface type we
14819 must generate the specification of the predefined primitives associated
14820 with controlled types (because the dispatch table of the ancestor is
14821 null and hence these entries cannot be inherited). This is required to
14822 elaborate well the dispatch table.

14830 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
14832 (Expand_N_In): Do validity checks on range
14833 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
14834 (Expand_N_Allocator): For "new T", if the object is constrained by
14835 discriminant defaults, allocate the right amount of memory, rather than
14836 the maximum for type T.
14837 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
14838 when the allocator is initialized by a build-in-place call, since the
14839 allocator is already rewritten as a reference to the function result,
14840 and this prevents an unwanted duplication of the function call.
14841 Add with and use of Exp_Ch6.
14842 (Expand_Allocator_Expresssion): Check for an allocator whose expression
14843 is a call to build-in-place function and apply
14844 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
14845 untagged designated types).
14846 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
14847 optimization if source or target is biased.
14848 (Expand_N_Allocator): Add comments for case of an allocator within a
14849 function that returns an anonymous access type designating tasks.
14850 (Expand_N_Allocator): apply discriminant checks for access
14851 discriminants of anonymous access types (AI-402, AI-416)

14856 Ed Schonberg <schonberg@adacore.com>
14858 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
14860 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
14861 (Expand_N_Assignment_Statement): Call
14862 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
14863 build-in-place function call. Currently, this can happen only for
14864 assignments that come from aggregates.
14865 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
14866 in order to alleviate the upward compatibility introduced by AI-318.
14867 (Expand_N_Extended_Return_Statement): Add support for handling the
14868 return object as a build-in-place result.
14869 (Expand_Non_Function_Return): Implement simple return statements nested
14870 within an extended return.
14871 (Enable_New_Return_Processing): Turn on the new processing of return
14873 (Expand_Non_Function_Return): For a return within an extended return,
14874 don't raise Program_Error, because Sem_Ch6 now gives a warning.
14875 (Expand_N_Extended_Return_Statement): Implement AI-318
14876 (Expand_Simple_Function_Return): Ditto.
14877 (Expand_N_If_Statement): Handle new -gnatwt warning
14878 (Expand_N_Case_Statement): Handle new -gnatwt warning
14879 (Expand_N_Assignment): Handle assignment to the Priority attribute of
14880 a protected object.
14881 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
14882 validity checking of assignments to elementary record components.
14883 (Expand_N_Return_Statement): return Class Wide types on the secondary
14884 stack independantly of their controlled status since with HIE runtimes,
14885 class wide types are not potentially controlled anymore.
14887 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
14890 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
14891 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
14892 it expects a block, procedure, or task. The return statement will get
14893 turned into a block, and Expand_Cleanup_Actions will happen then.

14897 Bob Duff <duff@adacore.com>
14898 Gary Dismukes <dismukes@adacore.com>
14900 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
14902 (Expand_Inlined_Call): Tagged types are by-reference types, and
14903 therefore should be replaced by a renaming declaration in the expanded
14904 body, as is done for limited types.
14905 (Expand_Call): If this is a call to a function with dispatching access
14906 result, propagate tag from context.
14907 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
14909 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
14910 build-in-place when the right-hand side of an assignment is a
14911 build-in-place function call.
14912 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
14913 of the explicit dereference of the allocator to the result subtype of
14914 the build-in-place function. This is needed to satisfy type checking
14915 in cases where the caller's return object is created by an allocator for
14916 a class-wide access type and the type named in the allocator is a
14918 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
14919 conversion of the reference to the declared object to the result subtype
14920 of the build-in-place function. This is needed to satisfy type checking
14921 in cases where the declared object has a class-wide type. Also, in the
14922 class-wide case, change the type of the object entity to the specific
14923 result subtype of the function, to avoid passing a class-wide object
14924 without explicit initialization to the back end.
14925 (Register_Interface_DT_Entry): Moved outside the body of
14926 Freeze_Subprogram because this routine is now public; it is called from
14927 Check_Dispatching_Overriding to handle late overriding of abstract
14928 interface primitives.
14929 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
14930 adding an implicit access actual on a call to a build-in-place function.
14931 (Expand_Actuals): Test for an actual parameter that is a call to a
14932 build-in-place function and apply
14933 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
14934 (Is_Build_In_Place_Function): New function to determine whether an
14935 entity is a function whose calls should be handled as build-in-place.
14936 (Is_Build_In_Place_Function_Call): New function to determine whether an
14937 expression is a function call that should handled as build-in-place.
14938 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
14939 calls to build-in-place functions as the initialization of an allocator.
14940 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
14941 handling calls to build-in-place functions in contexts that do not
14942 involve init of a separate object (for example, actuals of subprogram
14944 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
14945 handling calls to build-in-place functions as the initialization of an
14946 object declaration.
14947 (Detect_Infinite_Recursion): Add explicit parameter Process to
14948 instantiation of Traverse_Body to avoid unreferenced warning.
14949 (Check_Overriding_Inherited_Interfaces): Removed.
14950 (Register_Interface_DT_Entry): Code cleanup.
14951 (Register_Predefined_DT_Entry): Code cleanup.
14952 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
14953 inlined statements if within a transient scope.
14954 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
14955 formal parameters with occurrences of actuals in inlined body, establish
14956 visibility on the proper view of the actual's subtype for the body's
14958 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
14959 compatibility mode and we have an imported CPP subprogram because
14960 for now we assume that imported CPP primitives correspond with
14961 objects whose constructor is in the CPP side (and therefore we
14962 don't need to generate code to register them in the dispatch table).
14963 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
14964 aligned selected component.
14965 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
14966 the actual of an in-mode parameter is a type conversion.
14967 (Expand_Actuals): If the call does not come from source and the actual
14968 is potentially misaligned, let gigi handle it rather than rejecting the
14969 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
14970 Class Wide types as returning by reference independantly of their
14971 controlled status since with HIE runtimes class wide types are not
14972 potentially controlled anymore.
14974 2006-10-31 Ed Schonberg <schonberg@adacore.com>
14976 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
14977 references that are private components of the protected object.
14978 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
14979 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
14980 instantiation to deal with warnings.
14981 (Initialize_Protection): If expression for priority is non-static, use
14982 System_Priority as its expected type, in case the expression has not
14985 2006-10-31 Robert Dewar <dewar@adacore.com>
14987 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
14988 initialization of Homonym_Len.
14989 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
14990 names from fully qualified name. Fixes problem of duplicate
14991 external names differing only in the presence of such a block name.
14993 2006-10-31 Thomas Quinot <quinot@adacore.com>
14994 Pablo Oliveira <oliveira@adacore.com>
14996 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
14997 subprogram Ids, even if they are not yet assigned.
14998 (Build_Subprogram_Id): It is now this function that will take care of
14999 calling Assign_Subprogram_Ids if necessary.
15000 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
15001 should be done only once they are assigned.
15002 (Build_From_Any_Function, case of tagged types): Add missing call to
15004 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
15005 type for an RACW type.
15006 (Add_RACW_Features): When processing an RACW declaration for which the
15007 designated type is already frozen, enforce E.2.2(14) rules immediately.
15008 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
15009 special reordering of controlling formals.
15011 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
15012 associated stub type for an RACW type.
15014 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15016 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
15017 fixed-point operations in an integer context, i.e. as operands of a
15018 conversion to an integer type, indicate that result must be rounded.
15020 2006-10-31 Robert Dewar <dewar@adacore.com>
15022 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
15023 cases, pass the encoding method, since it is now required by the run
15026 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
15027 assumption that Str'First = 1.
15028 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
15029 it on to the Value_Wide_Wide_Character call.
15030 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
15031 properly handles a string of the form quote-encoded_wide_char-quote.
15033 * s-wchcnv.adb: Minor reformatting
15035 2006-10-31 Javier Miranda <miranda@adacore.com>
15037 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
15038 run-time membership test to ensure that the constructed object
15039 implements the target abstract interface.
15041 2006-10-31 Robert Dewar <dewar@adacore.com>
15043 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
15044 Machine_Attribute pragma internally to implement the user pragma.
15045 Add processing for pragma Interface so that it is now completely
15046 equivalent to pragma Import.
15048 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
15049 so that it can be applied to all entities, including record components
15050 and enumeration literals.
15051 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
15052 priority ranges are correct, verify compatibility against task
15053 dispatching and locking policies, and if everything is correct an entry
15054 is added to the table containing priority specific dispatching entries
15055 for this compilation unit.
15056 (Delay_Config_Pragma_Analyze): Delay processing
15057 Priority_Specific_Dispatching pragmas because when processing the
15058 pragma we need to access run-time data, such as the range of
15059 System.Any_Priority.
15060 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
15061 Allow pragma Unreferenced as a context item
15062 Add pragma Preelaborable_Initialization
15063 (Analyze_Pragma, case Interface): Interface is extended so that it is
15064 now syntactically and semantically equivalent to Import.
15065 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
15066 insertion characters.
15067 Add handling for Pragma_Wide_Character_Encoding
15068 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
15069 never supercedes a real restriction, and that a real restriction
15070 always supercedes a warning.
15071 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

15076 Robert Dewar <dewar@adacore.com>
15078 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
15079 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
15080 Is_Inherently_Limited_Type, because return-by-reference has no meaning
15082 (Find_Node_To_Be_Wrapped): Use new method of determining the result
15083 type of the function containing a return statement, because the
15084 Return_Type field was removed. We now use the Return_Applies_To field.
15086 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
15087 (Build_Task_Image_Decl): If procedure is not called from an
15088 initialization procedure, indicate that function that builds task name
15089 uses the sec. stack. Otherwise the enclosing initialization procedure
15090 will carry the indication.
15091 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
15092 N_Object_Declaration instead.
15093 (Kill_Dead_Code): New interface to implement -gnatwt warning for
15094 conditional dead code killed, and change implementation accordingly.
15095 (Insert_Actions): Add N_Return_Object_Declaration case.
15096 Correct comment to mention N_Extension_Aggregate node.
15097 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
15098 attempts to save information for global variables which cannot be
15100 (Get_Current_Value_Condition): Handle conditions the other way round
15101 (constant on left). Also handle right operand of AND and AND THEN
15102 (Set_Current_Value_Condition): Corresponding changes
15103 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
15104 (Get_Current_Value_Condition): Handle simple boolean operands
15105 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
15106 (Get_Current_Value_Condition): If the variable reference is within an
15107 if-statement, does not appear in the list of then_statments, and does
15108 not come from source, treat it as being at unknown location.
15109 (Get_Current_Value_Condition): Enhance to allow while statements to be
15110 processed as well as if statements.
15111 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
15113 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
15114 of loop. This is safe now that we fixed Kill_Current_Values.
15115 (OK_To_Do_Constant_Replacement): Check whether current scope is
15116 Standard, before examining outer scopes.
15118 2006-10-31 Vincent Celier <celier@adacore.com>
15120 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
15121 When True, apply VMS treatment to children of packages A, G, I and S.
15124 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
15126 2006-10-31 Robert Dewar <dewar@adacore.com>
15127 Ed Schonberg <schonberg@adacore.com>
15129 * freeze.adb: Add handling of Last_Assignment field
15130 (Warn_Overlay): Supply missing continuation marks in error msgs
15131 (Freeze_Entity): Add check for Preelaborable_Initialization
15133 * g-comlin.adb: Add Warnings (Off) to prevent new warning
15135 * g-expect.adb: Add Warnings (Off) to prevent new warning
15137 * lib-xref.adb: Add handling of Last_Assignment field
15138 (Generate_Reference): Centralize handling of pragma Obsolescent here
15139 (Generate_Reference): Accept an implicit reference generated for a
15140 default in an instance.
15141 (Generate_Reference): Accept a reference for a node that is not in the
15142 main unit, if it is the generic body corresponding to an subprogram
15145 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
15147 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
15149 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
15151 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
15152 use clauses, to avoid messages on packages used to qualify, and also
15153 to avoid messages from obsolescent units.
15154 (Warn_On_Useless_Assignments): Don't generate messages for imported
15155 and exported variables.
15156 (Warn_On_Useless_Assignments): New procedure
15157 (Output_Obsolescent_Entity_Warnings): New procedure
15158 (Check_Code_Statement): New procedure
15160 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
15161 Change name Is_Ada_2005 to Is_Ada_2005_Only
15162 (Last_Assignment): New field for useless assignment warning
15164 2006-10-31 Olivier Hainque <hainque@adacore.com>
15166 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
15167 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
15169 2006-10-31 Bob Duff <duff@adacore.com>
15170 Robert Dewar <dewar@adacore.com>
15171 Ed Schonberg <schonberg@adacore.com>
15173 * g-awk.adb (Default_Session, Current_Session): Compile this file in
15174 Ada 95 mode, because it violates the new rules for AI-318.
15176 * g-awk.ads: Use overloaded subprograms in every case where we used to
15177 have a default of Current_Session. This makes the code closer to be
15178 correct for both Ada 95 and 2005.
15180 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
15181 code, relying on the fact that the compiler generates a warning
15182 instead of an error in -gnatg mode.
15184 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
15185 E_Return_Statement entity kind.
15186 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
15188 * par.adb (P_Interface_Type_Definition): Addition of one formal to
15189 report an error if the reserved word abstract has been previously found.
15190 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
15192 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
15193 parenthesized range attribute usage
15194 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
15196 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
15197 in the syntax for extended_return_statement. This is not in the latest
15198 RM, but the ARG is expected to issue an AI allowing this.
15199 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
15200 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
15201 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
15202 P_Return_Statement): Parse the new syntax for extended_return_statement.
15204 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
15205 Output_End_Missing): Add error-recovery code for the new
15206 extended_return_statement syntax; that is, the new E_Return entry on
15209 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
15210 limited to nonlimited, because otherwise we violate the new Ada 2005
15211 rules about returning limited types in function Create_AST_Handler in
15214 * sem.adb (Analyze): Add cases for new node kinds
15215 N_Extended_Return_Statement and N_Return_Object_Declaration.
15217 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
15218 type is in the same category as type of context before applying check,
15219 to prevent anomalies in instantiations.
15220 (Resolve_Aggregate): Remove test for limited components in aggregates.
15221 It's unnecessary in Ada 95, because if it has limited components, then
15222 it must be limited. It's wrong in Ada 2005, because limited aggregates
15224 (Resolve_Record_Aggregate): Move check for limited types later, because
15225 OK_For_Limited_Init requires its argument to have been resolved.
15226 (Get_Value): When copying the component default expression for a
15227 defaulted association in an aggregate, use the sloc of the aggregate
15228 and not that of the original expression, to prevent spurious
15229 elaboration errors, when the expression includes function calls.
15230 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
15231 were missing. We also didn't handle qualified expressions. Now also
15232 allow function calls. Use new common routine OK_For_Limited_Init.
15233 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
15234 with space can upper case letter).
15236 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
15237 Has_Static_Discriminants flag

15242 Denotes_Discriminant.
15243 (Process_Subtype): If the subtype is a private subtype whose full view
15244 is a concurrent subtype, introduce an itype reference to prevent scope
15246 (Build_Derived_Record_Type, Collect_Interface_Primitives,
15247 Record_Type_Declaration): The functionality of the subprograms
15248 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
15249 is now performed by a single routine.
15250 (Build_Derived_Record_Type): If the type definition includes an explicit
15251 indication of limitedness, then the type must be marked as limited here
15252 to ensure that any access discriminants will not be treated as having
15253 a local anonymous access type.
15254 (Check_Abstract_Overriding): Issue a detailed error message when an
15255 abstract subprogram was not overridden due to incorrect mode of its
15257 (Analyze_Private_Extension_Declaration): Add support for the analysis of
15258 synchronized private extension declarations. Verify that the ancestor is
15259 a limited or synchronized interface or in the generic case, the ancestor
15260 is a tagged limited type or synchronized interface and all progenitors
15261 are either limited or synchronized interfaces.
15262 Derived_Type_Declaration): Check for presence of private extension when
15263 dealing with synchronized formal derived types.
15264 Process_Full_View): Enchance the check done on the usage of "limited" by
15265 testing whether the private view is synchronized.
15266 Verify that a synchronized private view is completed by a protected or
15268 (OK_For_Limited_Init_In_05): New function.
15269 (Analyze_Object_Declaration): Move check for limited types later,
15270 because OK_For_Limited_Init requires its argument to have been resolved.
15271 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
15272 in order to alleviate the upward compatibility introduced by AI-318.
15273 (Constrain_Corresponding_Record): If the constraint is for a component
15274 subtype, mark the itype as frozen, to avoid out-of-scope references to
15275 discriminants in the back-end.
15276 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
15277 this subprogram against wrong sources.
15278 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
15279 discriminant of limited type completed with a protected type, when the
15280 discriminant is used to constrain a private component of the type, and
15281 expansion is disabled.
15282 (Find_Type_Of_Object): Do not treat a return subtype that is an
15283 anonymous subtype as a local_anonymous_type, because its accessibility
15284 level is the return type of the enclosing function.
15285 (Check_Initialization): In -gnatg mode, turn the error "cannot
15286 initialize entities of limited type" into a warning.
15287 (OK_For_Limited_Init): Return true for generated nodes, since it
15288 sometimes violates the legality rules.
15289 (Make_Incomplete_Declaration): If the type for which an incomplete
15290 declaration is created happens to be the currently visible entity,
15291 preserve the homonym chain when removing it from visibility.
15292 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
15293 inherited subprograms.
15294 (Access_Definition): If this is an access to function that is the return
15295 type of an access_to_function definition, context is a type declaration
15296 and the scope of the anonymous type is the current one.
15297 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
15298 incomplete subtype to the set of private dependents of the original
15300 (Constrain_Discriminated_Type): Emit an error message whenever an
15301 incomplete subtype is being constrained.
15302 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
15303 corresponding subtype of the full view of the original incomplete type.
15304 (Check_Incomplete): Properly detect invalid usage of incomplete types

15342 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
15343 call it with -static-libgcc, as there are some platforms, such as
15344 Darwin, where one of these two switches is compulsory to link.
15346 2006-10-31 Vincent Celier <celier@adacore.com>
15348 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
15349 instead of ADA_PROJECT_PATH, for the project path.
15350 (Gnatls): When displaying the project path directories, use host dir
15353 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
15354 names in the project path, as absolute paths may correspond to
15355 multi-valued VMS logical names.

15388 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
15390 (Layout_Variant_Record): Retrieve the discriminants from the entity
15391 rather than from the type definition, because in the case of a full
15392 type for a private type we need to take the discriminants from the
15394 (Layout_Component_List): When applying the Max operator to variants with
15395 a nonstatic size, check whether either operand is static and scale that
15396 operand from bits to storage units before applying Max.
15397 (Layout_Type): In VMS, if a C-convention access type has no explicit
15398 size clause (and does not inherit one in the case of a derived type),
15399 then the size is reset to 32 from 64.
15401 2006-10-31 Vincent Celier <celier@adacore.com>
15403 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
15404 its file has already been loaded, according to the unit being loaded,
15405 not to the current value of Multiple_Unit_Index.

15443 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15445 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
15446 Process_Body_Clauses): If the context of a body includes a use clause
15447 for P.Q then a with_clause for P in the same body is not redundant,
15448 even if the spec also has a with_clause on P.
15449 Add missing continuation mark to error msg
15450 (Build_Limited_Views): A limited view of a type is tagged if its
15451 declaration includes a record extension.
15452 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
15453 node, even if the subunit has errors. This avoids malfunction by
15454 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
15455 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
15456 generation of obsolescent messages for with statements (cannot do
15457 this too early, or we cannot implement avoiding the messages in the
15458 case of obsolescent units withing obsolescent units).
15459 (Install_Siblings): If the with_clause is on a remote descendant of
15460 an ancestor of the current compilation unit, find whether there is
15461 a sibling child unit that is immediately visible.
15462 (Remove_Private_With_Clauses): New procedure, invoked after completing
15463 the analysis of the private part of a nested package, to remove from
15464 visibility the private with_clauses of the enclosing package

15467 now centralized in Generate_Reference.
15468 (Install_Limited_Context_Clauses): Remove superfluous error
15469 message associated with unlimited view visible through use
15470 and renamings. In addition, at the point in which the error
15471 is reported, we add the backslash to the text of the error
15472 to ensure that it is reported as a single error message.
15473 Use new // insertion for some continuation messages
15474 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
15475 to create implicit with_clause for parent unit mentioned in original
15476 limited_with_clause.
15477 (Install_Limited_With_Unit): Set entity of parent identifiers if the
15478 unit is a child unit. For ASIS queries.

15543 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
15544 dot, instead of replacing only the first '_'.
15546 * prj-part.adb (Parse): Convert project file path to canonical form
15548 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
15549 extended, the project id of the project extending it is recorded in its

15558 Robert Dewar <dewar@adacore.com>
15560 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
15561 only a restriction warning is active for the given restriction. This is
15562 desirable because we do not want to modify code in the case where only
15564 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
15565 causes overriding of real restrictions.
15566 Take advantage of new No_Restrictions constant.
15568 * raise.h: (__gnat_set_globals): Change profile.
15570 2006-10-31 Arnaud Charlet <charlet@adacore.com>

15599 Generalizes previous mechanism to handle attribute references nested
15600 arbitrarily deep within the aggregate.
15601 (Analyze_Access_Attribute): An access attribute whose prefix is a type
15602 can appear in an aggregate if this is a default-initialized aggregate
15603 for a self-referential type.

15617 a class-wide interface to a tagged type.
15618 Add support for the attribute Priority.
15619 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
15620 whether the designated type is discriminated with a constrained partial
15621 view and require static matching in that case.
15622 Add local variable Des_Btyp. The Designated_Type
15623 of an access to incomplete subtype is either its non-limited view if
15624 coming from a limited with or its etype if regular incomplete subtype.
15626 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
15627 Fix predicate to identify and allow cases of (expander-generated)
15628 references to tag of designated object of a RACW.
15629 (Validate_Static_Object_Name): In Ada 2005, a formal object is

15643 useless assignments here and conditionalize it on absence of exception
15645 (Analyze_Exception_Handlers): Small code reorganization of error
15646 detection code, for new handling of formal packages.

15659 synchronized formal derived type is a synchronized tagged type.
15660 (Instantiate_Formal_Package): When creating the instantiation used to
15661 validate the actual package of a formal declared without a box, check
15662 whether the formal itself depends on a prior actual.
15663 (Instantiate_Formal_Subprogram): Create new entities for the defining
15664 identifiers of the formals in the renaming declaration, for ASIS use.
15665 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
15666 a renaming declaration or a subtype declaration for an actual in an
15667 instance, capture location information of declaration in generic, for

15670 AI-317 (partial parametrization) is fully implemented.
15671 (Validate_Private_Type_Instance): Add check for actual which
15672 must have preelaborable initialization
15673 Use new // insertion for some continuation messages
15674 (Analyze_Formal_Object_Declaration): Change usage of Expression to
15675 Default_Expression. Add type retrieval when the declaration has an
15676 access definition. Update premature usage of incomplete type check.
15677 (Check_Access_Definition): New subsidiary routine. Check whether the
15678 current compilation version is Ada 05 and the supplied node has an
15680 (Instantiate object): Alphabetize local variables. Handle the creation
15681 of new renaming declarations with respect to the kind of definition
15682 used - either an access definition or a subtype mark. Guard against
15683 unnecessary error message in the context of anonymous access types after
15684 they have been resolved. Add check for required null exclusion in a
15685 formal object declaration.
15686 (Switch_View): A private subtype of a non-private type needs to be
15687 switched (the base type can have been switched without its private
15688 dependents because of the last branch of Check_Private_View.
15689 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
15691 (Instantiate_Type): Emit an error message whenever a class-wide type of
15692 a tagged incomplete type is used as a generic actual.
15693 (Find_Actual_Type): Extend routine to handle a component type in a child
15694 unit that is imported from a formal package in a parent.
15695 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
15696 agree on constrainedness, rather than checking against ultimate ancestor
15697 (Instantiate_Subprogram_Body): Create a cross-reference link to the
15698 generic body, for navigation purposes.

15705 (New_Stream_Subprogram): When processing an attribute definition clause
15706 for a stream-oriented subprogram, record an entity node occurring at
15707 the point of clause to use for checking the visibility of the clause,
15708 as defined by 8.3(23) as amended by AI-195.
15709 (New_Stream_Subprogram): New procedure, factoring behaviour from both
15710 New_Stream_Function and New_Stream_Procedure.
15711 (New_Stream_Function, New_Stream_Procedure): Removed.
15712 (Analyze_Attribute_Definition_Clause, case Address): Check new
15713 Alignment_Check check

15716 Javier Miranda <miranda@adacore.com>
15717 Robert Dewar <dewar@adacore.com>
15719 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
15720 generate the same errors compiling under -gnatc.
15721 (Try_Object_Operation): If no candidate interpretation succeeds, but
15722 there is at least one primitive operation with the right name, report
15723 error in call rather than on a malformed selected component.
15724 (Analyze_Selected_Component): If the prefix is an incomplete type from
15725 a limited view, and the full view is available, use the full view to
15726 determine whether this is a prefixed call to a primitive operation.
15727 (Operator_Check): Verify that a candidate interpretation is a binary
15728 operation before checking the type of its second formal.
15729 (Analyze_Call): Add additional warnings for function call contexts not
15731 (Analyze_Allocator): Move the check for "initialization not allowed for
15732 limited types" after analyzing the expression. This is necessary,
15733 because OK_For_Limited_Init looks at the structure of the expression.
15734 Before analysis, we don't necessarily know what sort of expression it
15735 is. For example, we don't know whether F(X) is a function call or an
15736 indexed component; the former is legal in Ada 2005; the latter is not.
15737 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
15738 were missing. We also didn't handle qualified expressions. Now also
15739 allow function calls. Use new common routine OK_For_Limited_Init.
15740 (Analyze_Type_Conversion): Do not perform some legality checks in an
15741 instance, because the error message will be redundant or spurious.
15742 (Analyze_Overloaded_Selected_Component): Do not do style check when
15743 setting an entity, since we do not know it is the right entity yet.
15744 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
15745 (Analyze_Overloaded_Selected_Component): Same change
15746 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
15747 since regular incomplete subtypes are transformed into corresponding
15748 subtypes of their full views.
15749 (Complete_Object_Operation): Treat name of transformed subprogram call
15750 as coming from source, for browsing purposes.
15751 (Try_Primitive_Operation): If formal is an access parameter, compare
15752 with base type of object to determine whether it is a primitive
15754 (Operator_Check): If no interpretation of the operator matches, check
15755 whether a use clause on any candidate might make the operation legal.
15756 (Try_Class_Wide_Operation): Check whether the first parameter is an
15757 access type whose designated type is class-wide.
15759 2006-10-31 Robert Dewar <dewar@adacore.com>
15760 Ed Schonberg <schonberg@adacore.com>
15761 Gary Dismukes <dismukes@adacore.com>
15763 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
15764 warn on infinite loops.
15765 Add \\ to some continuation messages
15766 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
15767 (Process_Bounds): If the bounds are integer literals that result from
15768 constant-folding, and they carry a user-defined type, preserve that type
15769 rather than treating this as an integer range.
15770 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
15771 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
15772 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
15773 left hand side of assignment.
15774 (Analyze_Assignment): Add suport to manage assigments to the attribute
15775 priority of a protected object.
15776 (Check_Possible_Current_Value_Condition): Allow fully qualified names
15777 not just identifiers.
15778 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
15779 or AND THEN for possible tracking.
15780 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
15781 case of while loops so we can track values in the loop body.
15783 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15784 Hristian Kirtchev <kirtchev@adacore.com>
15785 Bob Duff <duff@adacore.com>
15787 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
15788 procedure cannot be a protected operation (it is a basic_declaration,
15789 not a subprogram_declaration).
15790 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
15791 Subp. Add logic for entry processing.
15792 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
15793 Determine whether an entry or subprogram of a protected or task type
15794 override an inherited primitive of an implemented interface.
15795 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
15796 Update the actual used in calls to Check_Overriding_Indicator.
15797 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
15798 generate the proper reference to the parent unit, for cross-reference.
15799 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
15801 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
15802 (Add_Extra_Formal): Revise procedure to allow passing in associated
15803 entity, scope, and name suffix, and handle setting of the new
15804 Extra_Formals field.
15805 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
15806 pass new parameters. Add support for adding the new extra access formal
15807 for functions whose calls are treated as build-in-place.
15808 (Analyze_A_Return_Statement): Correct casing in error message.
15809 Move Pop_Scope to after Analyze_Function_Return, because an extended
15810 return statement really is a full-fledged scope. Otherwise, visibility
15811 doesn't work right. Correct use of "\" for continuation messages.
15812 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
15813 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
15814 the node doesn't get properly marked as analyzed.
15815 (Analyze_Subprogram_Body): If subprogram is a function that returns
15816 an anonymous access type that denotes a task, build a Master Entity
15818 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
15819 proper usage of null exclusion in a result definition.
15820 (Process_Formals): Code cleanup and new error message.
15821 (Process_Formals): Detect incorrect application of null exclusion to
15823 (Conforming_Types): Handle conformance between [sub]types and itypes
15824 generated for entities that have null exclusions applied to them.
15825 (Maybe_Primitive_Operation): Add an additional type retrieval when the
15826 base type is an access subtype. This case arrises with null exclusions.
15827 (New_Overloaded_Entity): Do not remove the overriden entity from the
15828 homonym chain if it corresponds with an abstract interface primitive.
15829 (Process_Formals): Replace membership test agains Incomplete_Kind with a
15830 call to the synthesized predicate Is_Incomplete_Type.
15831 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
15833 (Analyze_Subprogram_Declaration): Check that abstract interface
15834 primitives are abstract or null.
15835 (Analyze_Subprogram_Specification): Remove previous check for abstract
15836 interfaces because it was not complete.
15837 (Has_Interface_Formals): Removed.
15839 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15840 Javier Miranda <miranda@adacore.com>
15842 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
15843 of Analyze_Package_Body, to create Itype references for anonymous
15844 access types created in the package declaration, whose designated types
15845 may have only a limited view.
15846 (Analyze_Package_Specification): For the private part of a nested
15847 package, install private_with_clauses of enclosing compilation unit if
15848 we are in its visible part.
15849 (Declare_Inherited_Private_Subprograms): Complete barrier
15850 to ensure that the primitive operation has an alias to some parent
15851 primitive. This is now required because, after the changes done for the
15852 implementation of abstract interfaces, the contents of the list of
15853 primitives has entities whose alias attribute references entities of
15854 such list of primitives.
15855 (Analyze_Package_Specification): Simplify code that handles parent units
15856 of instances and formal packages.
15857 (Uninstall_Declarations): Check the convention consistency among
15858 primitive overriding operations of a tagged record type.
15860 2006-10-31 Robert Dewar <dewar@adacore.com>

15862 Javier Miranda <miranda@adacore.com>
15863 Ed Schonberg <schonberg@adacore.com>
15865 * sem_ch8.adb: Minor error msg rewording
15866 (Undefined): When checking for misspellings, invert arguments (to get
15867 expected and found set right)
15868 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
15869 (Analyze_Generic_Renaming): Same fix
15870 (Use_One_Package): Do not take into account the internal entities of
15871 abstract interfaces during the analysis of entities that are marked
15872 as potentially use-visible.
15873 (Find_Type): Handle the case of an attribute reference for
15874 implementation defined attribute Stub_Type (simply let the analysis of
15875 the attribute reference rewrite it).
15876 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
15877 type that appears in a Use_Type clause.
15878 (Analyze_Object_Renaming): Add support for renaming of the Priority
15880 (Find_Type): In Ada 2005, a task type can be used within its own body,
15881 when it appears in an access definition.
15882 (Analyze_Object_Renaming): Remove warning on null_exclusion.
15883 (Analyze_Object_Renaming): Introduce checks for required null exclusion
15884 in a formal object declaration or in a subtype declaration.
15885 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
15886 (Check_Null_Exclusion): New local routine to
15887 Analyze_Subprogram_Renaming. Check whether the formals and return
15888 profile of a renamed subprogram have required null exclusions when
15889 their counterparts of the renaming already impose them.
15890 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
15891 Determine whether an entity is inside a generic scope.
15892 (In_Open_Scope): First pass of documentation update.
15893 (Find_Expanded_Name): Add support for shadow entities associated with
15894 limited withed packages. This is required to handle nested packages.
15895 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
15896 that makes a renaming of a limited withed package illegal.
15898 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
15899 Ed Schonberg <schonberg@adacore.com>
15901 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
15902 Check_Overriding_Indicator.
15903 (Analyze_Task_Definition): Ditto.
15904 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
15905 (Check_Overriding_Indicator): To find overridden interface operation,
15906 examine only homonyms that have an explicit subprogram declaration, not
15907 inherited operations created by an unrelated type derivation.
15908 (Check_Overriding_Indicator): When checking for the presence of "null"
15909 in a procedure, ensure that the queried node is a procedure
15911 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
15912 type when the formal is an access to variable.
15913 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
15914 (Analyze_Task_Type): Same addition
15915 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
15916 provide navigation capabilities for entries.

15920 Javier Miranda <miranda@adacore.com>
15921 Gary Dismukes <dismukes@adacore.com>
15923 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
15924 inherited from an interface ancestor by another interface in the
15925 context of an instance as 'late'.
15926 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
15927 of a call to a function that dispatches on access result.
15928 (Check_Dispatching_Operation): In case of late overriding of a primitive
15929 that covers abstract interface subprograms we register it in all the
15930 secondary dispatch tables associated with abstract interfaces.
15931 (Check_Dispatching_Call): Add check that a dispatching call is not made
15932 to a function with a controlling result of a limited type. This is a
15933 current implementation restriction.
15934 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
15935 (Check_Dispatching_Operation): Do no emit a warning if the controlling
15936 argument is an interface type that is a generic formal.
15937 (Is_Interface_Subprogram): Removed.
15938 (Check_Dispatching_Operation): If the subprogram is not a dispatching
15939 operation, check the formals to handle the case in which it is
15940 associated with an abstract interface type.
15942 2006-10-31 Robert Dewar <dewar@adacore.com>
15943 Ed Schonberg <schonberg@adacore.com>

15953 Current_Value in the conditional case, to evaluate additional
15954 comparisons at compile time.

15957 Hristian Kirtchev <kirtchev@adacore.com>
15958 Javier Miranda <miranda@adacore.com>
15960 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
15961 subprogram type to provide better diagnostics in case of ambiguity.
15962 (Covers): Handle coverage of formal and actual anonymous access types in
15963 the context of generic instantiation.
15964 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
15965 abstract interface types; this is required to handle concurrent types
15966 with discriminants and abstract interface types.
15967 (Covers): Include type coverage of both regular incomplete subtypes and
15968 incomplete subtypes of incomplete type visibles through a limited with

15980 Add missing continuation marks in error msgs
15981 (Unqualify): New function for removing zero or more levels of
15982 qualification from an expression. There are numerous places where this
15983 ought to be used, but we currently only deal properly with zero or one
15985 (In_Instance); The analysis of the actuals in the instantiation of a
15986 child unit is not within an instantiation, even though the parent
15987 instance is on the scope stack.
15988 (Safe_To_Capture_Value): Exclude the case of variables that are
15990 (Check_Obsolescent): Removed
15991 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
15992 is an aliased view, even when rewritten as a reference to the target
15993 object in an assignment.
15994 (Get_Subprogram_Entity): New function
15995 (Known_To_Be_Assigned): New function
15996 (Type_Access_Level): Compute properly the access level of a return

16003 has a null exclusion depending on its Nkind.
16004 Change Is_Lvalue to May_Be_Lvalue
16005 (May_Be_Lvalue): Extensive additional code to deal with subprogram
16006 arguments (IN parameters are not Lvalues, IN OUT parameters are).
16007 (Safe_To_Capture_Value): Extend functionality so it can be used for
16008 the current value condition case.
16009 (Has_Compatible_Alignment): New function
16010 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
16011 objects to handle the Ada 2005 case, where aliasedness no longer implies
16012 that the object is constrained. In particular, for dereferenced names,
16013 the designated object must be assumed to be unconstrained.
16014 (Kill_Current_Values): Properly deal with the case where we encounter
16015 a loop in the scope chain.
16016 (Safe_To_Capture_Value): Do not let a loop stop us from capturing

16026 * s-osinte-tru64.adb:
16027 Mark Asm statements Volatile to prevent warnings (seems a
16028 reasonable change anyway)
16031 * s-mastop-irix.adb: Add Volatile to Asm statements
16032 Suppresses warning, and seems appropriate in any case
16034 * s-osinte-vms.adb: Add Volatile to Asm statement

16051 contain a reference to the enclosing type, inserted through a default
16053 (Next_Rep_Item): Move from Node4 to Node5.
16054 (Entity): Add this field for N_Attribute_Definition_Clause.
16055 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
16056 (N_Return_Object_Declaration): Remove this node kind. We now use

16058 (Actual_Designated_Subtype): Move to a different place to make room in
16059 N_Extended_Return_Statement.
16060 (Procedure_To_Call): Move to a different place to make room in
16061 N_Extended_Return_Statement.
16062 (Return_Type): Removed this field to make room in return statements
16064 (Return_Statement_Entity): New field in return statements, in part to
16065 replace Return_Type, and in part to support the fact that return
16066 statements are now pushed on the scope stack during semantic analysis.
16067 (Return_Object_Declarations): New field to support extended return
16069 (N_Extended_Return_Statement): New node for extended_return_statement
16071 (N_Return_Object_Declaration): New node for part of
16072 extended_return_statement nonterminal. Needed because all the necessary
16073 fields won't fit in N_Extended_Return_Statement.
16074 Generic_associations now carry the Box_Present flag, to indicate a
16075 default for an actual in a partially parametrized formal package.
16077 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
16078 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma
16079 and for the new predefined dispatching policies: EDF_Across_Priorities,

16093 print null exclusion twice in the case of an access definition,
16094 Implement new -gnatL switch
16095 Remove N_Return_Object_Declaration. We now use
16096 N_Object_Declaration instead. Implement the case for
16097 N_Extended_Return_Statement. Alphabetize the cases.
16098 Add cases for new nodes N_Extended_Return_Statement and
16099 N_Return_Object_Declaration. The code is not yet written.
16100 Update the output for N_Formal_Object_Declaration
16101 and N_Object_Renaming_Declaration.

16120 * s-scaval.adb (Initialize): Add new Boolean flag AFloat that is set
16121 True when AAMP extended floating-point is in use (48-bit). Change type
16122 ByteLF to ByteLLF, add new array type ByteLF and condition the size of
16123 the two byte array types on AFloat. Change type of IV_Ilf overlay
16124 variable from Byte8 to ByteLF. Add appropriate initializations of
16125 floating-point overlays for AAMP cases.

16147 * widechar.adb (Is_Start_Of_Wide_Char): In case of brackets encoding,
16148 add more precise check for the character sequence that follows '[' to

16712 2006-02-17 Vasiliy Fofanov <fofanov@adacore.com>
16714 * Makefile.in: Use VMS64 specialized versions of several units in
16715 Interfaces.C hierarchy to be compatible with HP C default size choices.
16716 Use the default version of Ada.Synchronous_Task_Control for VxWorks 653.
16718 2006-02-17 Ed Schonberg <schonberg@adacore.com>
16720 * sem_ch10.adb (Analyze_With_Clause): If the unit is a subprogram
16721 instantiation, the corresponding entity is the related_instance of the
16722 wrapper package created for the instance.
16724 2006-02-17 Ed Schonberg <schonberg@adacore.com>
16726 * sem_ch12.adb (Analyze_Package_Instantiation): Inline_Now is false if
16727 the current instance is nested within another instance in a child unit.

16730 Ed Schonberg <schonberg@adacore.com>
16732 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
16733 type we cannot inherit the primitive operations; we inherit the
16734 Corresponding_Record_Type (which has the list of primitive operations).
16735 (Check_Anonymous_Access_Types): When creating anonymous access types for
16736 access components, use Rewrite in order to preserve the tree structure,
16738 (Analyze_Object_Declaration): For limited types with access
16739 discriminants with defaults initialized by an aggregate, obtain
16740 subtype from aggregate as for other mutable types.
16741 (Derived_Type_Declaration): If the derived type is a limited interface,
16742 set the corresponding flag (Is_Limited_Record is not sufficient).

16748 expression must be the first variable declared in the body of the
16751 2006-02-17 Javier Miranda <miranda@adacore.com>
16753 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
16754 abstract interface type, the static analysis is not enough to know if
16755 the interface is implemented or not by the source tagged type. Hence
16756 we must pass the work to the expander to generate the required code to
16757 evaluate the conversion at run-time.
16758 (Resolve_Equality_Op): Do not apply previous
16759 transformation if expansion is disasbled, to prevent anomalies when
16760 locating global references in a generic unit.

16940 table to take advantage of the 16 priority levels available on Windows
16941 2000 and XP. On NT4 there are only 7 priority levels, this is properly
16942 supported by this new mapping.

16988 (Read): Change the implementation to support unicode characters. It is
16989 not possible to use strlen() on Windows as this version supports only
16990 standard ASCII characters. So the length of the directory entry is now
16991 returned from the imported __gnat_readdir routine.

17029 E_Floating_Point_Subtype>: Inherit alias set of what we are making a
17030 subtype of to ensure conflicts amongst all subtypes in a hierarchy,
17031 necessary since these are not different types and pointers may
17032 actually designate any subtype in this hierarchy.
17033 (gnat_to_gnu_entity, case E_Record_Type): Always make fields for
17034 discriminants but put them into record only if not Unchecked_Union;

17037 components before variants; don't set TYPE_UNCHECKED_UNION_P.

17039 Remove special case code for Unchecked_Union and instead use main code
17040 with small changes.
17043 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
17044 variable with the expression being built, only its inner field.

17054 substituted for a CONST_DECL.
17055 (tree_transform, case N_Aggregate): Remove code for UNION_TYPE and pass

17057 (assoc_to_constructor): New argument, GNAT_ENTITY; use it to ignore
17058 discriminants of Unchecked_Union.
17059 (TARGET_ABI_OPEN_VMS): Define to 0 if not defined, so that later uses
17060 don't need cluttering preprocessor directives.
17061 (establish_gnat_vms_condition_handler): New function. Establish the GNAT
17062 condition handler as current in the compiled function.
17063 (body_with_handlers_p): New function. Tell whether a given sequence of
17064 statements node is attached to a package or subprogram body and involves
17065 exception handlers possibly nested within inner block statements.
17066 (emit_sequence_entry_statements): New function, to emit special
17067 statements on entry of sequences when necessary. Establish GNAT
17068 condition handler in the proper cases for VMS.

17098 other basic tools. The full version that includes the Ada 2005 stuff
17099 is in separate files a-except-2005.ads/adb. The reason is that we do
17100 not want to cause bootstrap problems with compilers not recognizing

17561 operations or the parent type.

17567 function generated by the expander to get such value; otherwise use
17568 the value stored in the table of interfaces.
17569 (Offset_To_Top): The type of the actual has been changed to Address to
17570 give the correct support to tagged types with discriminants. In this
17571 case this value is stored just immediately after the tag field.
17572 (Set_Offset_To_Top): Two new formals have been added to indicate if the
17573 offset_to_top value is static and hence pass this value to the run-time
17574 to store it in the table of interfaces, or else if this value is dynamic
17575 and then pass to the run-time the address of a function that is
17576 generated by the expander to provide this value for each object of the

17593 subprogram contains an inner block with an exception handler.
17594 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
17595 Adjust call is for a newly-allocated object. In that case we must not
17596 assume that the finalization list chain pointers are correct (since they
17597 come from a bit-for-bit copy of the original object's pointers) so if
17598 the attach level would otherwise be zero (no change), we set it to 4
17599 instead to cause the pointers to be reset to null.
17601 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
17602 reset chain pointers to null.
17604 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17606 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
17607 string, and the context requires a loop for the assignment (e.g.
17608 because the left-hand side is packed), generate a unique name for the
17609 temporary that holds the string, to prevent spurious name clashes.

17612 Javier Miranda <miranda@adacore.com>
17613 Robert Dewar <dewar@adacore.com>
17614 Gary Dismukes <dismukes@adacore.com>
17616 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
17617 return unconstrained arrays.
17619 (Expand_Call): An indirect call through an access parameter of a
17620 protected operation is not a protected call.
17621 Add circuit to raise CE in Ada 2005 mode following call
17622 to Raise_Exception.
17623 (Register_DT_Entry): Do nothing if
17624 the run-time does not give support to abstract interfaces.
17625 (Freeze_Subprogram): In case of dispatching operations, do not generate
17626 code to register the operation in the dispatch table if the source
17627 is compiled with No_Dispatching_Calls.
17628 (Register_Predefined_DT_Entry): Generate code that calls the new
17629 run-time subprogram Set_Predefined_Prim_Op_Address instead of
17630 Set_Prim_Op_Address.
17632 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
17633 on array assignments if the right-hand side is a function call that has
17634 been inlined. Check is performed on the assignment in the block.
17635 (Process_Bounds): If bounds and range are overloaded, apply preference
17636 rule for root operations to disambiguate, and diagnose true ambiguity.
17637 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
17638 a tag-indeterminate right-hand side even when Expander_Active is True.
17639 Needed to ensure that dispatching calls to T'Input are allowed and
17640 get the tag of the target class-wide object.
17642 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
17643 an inherited primitive operation that already overrides several
17644 abstract interface primitives. For transitivity, the new entity must
17645 also override all the abstract interface primitives covered by the
17646 inherited overriden primitive.
17647 Emit warning if new entity differs from homograph in same scope only in
17648 that one has an access parameter and the other one has a parameter of
17649 a general access type with the same designated type, at the same
17650 position in the signature.
17651 (Make_Inequality_Operator): Use source locations of parameters and
17652 subtype marks from corresponding equality operator when creating the
17653 tree structure for the implicit declaration of "/=". This does not
17654 change anything in behaviour except that the decoration of the
17655 components of the subtree created for "/=" allows ASIS to get the
17656 string images of the corresponding identifiers.
17657 (Analyze_Return_Statement): Remove '!' in warning message.
17658 (Check_Statement_Sequence): Likewise.
17659 (Analyze_Subprogram_Body): For an access parameter whose designated type
17660 is an incomplete type imported through a limited_with clause, use the
17661 type of the corresponding formal in the body.
17662 (Check_Returns): Implicit return in No_Return procedure now raises
17663 Program_Error with a compile time warning, instead of beging illegal.
17664 (Has_Single_Return): Function returning unconstrained type cannot be
17665 inlined if expression in unique return statement is not an identifier.
17666 (Build_Body_To_Inline): It is possible to inline a function call that
17667 returns an unconstrained type if all return statements in the function
17668 return the same local variable. Subsidiary procedure Has_Single_Return
17669 verifies that the body conforms to this restriction.
17671 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
17672 same type, and one of them is of an anonymous access type, convert
17673 the other operand to it, so that this is a valid binary operation for
17675 (Resolve_Type_Conversion): Handle subtypes of protected types and
17676 task types when accessing to the corresponding record type.
17677 (Resolve_Allocator): Add '\' in 2-line warning message.
17678 Remove '!' in warning message.
17679 (Resolve_Call): Add '\' in 2-line warning message.
17680 (Valid_Conversion): Likewise.
17681 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
17682 resulting type may be an access type with an implicit dereference.
17683 Obtain the proper component from the designated type.
17684 (Make_Call_Into_Operator): Handle properly a call to predefined equality
17685 given by an expanded name with prefix Standard, when the operands are
17686 of an anonymous access type.
17687 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
17688 Explicit_Dereference and Resolve_Selected_Component, to verify that the
17689 prefix of the expression is not of an incomplete type. Allows full
17690 diagnoses of all semantic errors.
17691 (Resolve_Actuals): If the actual is an allocator whose directly
17692 designated type is a class-wide interface we build an anonymous
17693 access type to use it as the type of the allocator. Later, when
17694 the subprogram call is expanded, if the interface has a secondary
17695 dispatch table the expander will add a type conversion to force
17696 the displacement of the pointer.
17697 (Resolve_Call): If a function that returns an unconstrained type is
17698 marked Inlined_Always and inlined, the call will be inlined and does
17699 not require the creation of a transient scope.
17700 (Check_Direct_Boolean_Op): Removed
17701 (Resolve_Comparison_Op): Remove call to above
17702 (Resolve_Equality_Op): Remove call to above
17703 (Resolve_Logical_Op): Inline above, since this is only call.
17704 (Valid_Conversion): Handle properly conversions between arrays of
17705 convertible anonymous access types.
17708 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
17709 the literal in an unchecked conversion, because GCC 4.x needs a static
17710 value for a string bound.
17712 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17713 Hristian Kirtchev <kirtchev@adacore.com>
17715 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
17716 components of the corresponding record, take into account component
17717 definitions that are access definitions.
17718 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
17719 procedure is not considered a dispatching call and will be expanded
17722 2006-02-13 Javier Miranda <miranda@adacore.com>
17724 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
17725 controlling argument of the dispatching call is an abstract interface
17726 class-wide type then we use it directly.
17727 Check No_Dispatching_Calls restriction.
17728 (Default_Prim_Op_Position): Remove the code that looks for the last
17729 entity in the list of aliased subprograms. This code was wrong in
17731 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
17732 when the source is compiled with the No_Dispatching_Calls restriction.
17733 (Init_Predefined_Interface_Primitives): No need to inherit primitives
17734 if we are compiling with restriction No_Dispatching_Calls.
17735 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
17736 subprograms if we are compiling under No_Dispatching_Calls restriction.
17737 (Make_DT): Generate a dispatch table with a single dummy entry if
17738 we are compiling with the No_Dispatching_Calls restriction. In
17739 addition, in this case we don't generate code that calls to the
17740 following run-time subprograms: Set_Type_Kind, Inherit_DT.
17741 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
17742 of this subprogram if compiling with the No_Dispatching_Calls
17744 (Expand_Type_Conversion): Instead of using the actual parameter,
17745 the argument passed as parameter to the conversion function was
17746 erroneously referenced by the expander.
17747 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
17748 Set_Predefined_Primitive_Op_Address and Set_Signature.
17749 (Expand_Dispatching_Call): Generate call to
17750 Get_Predefined_Prim_Op_Address for predefined primitives.
17751 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
17752 predefined primitives.
17753 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
17754 primitives we reserve one dummy entry to ensure that the tag does not
17755 point to some memory that is associated with some other object. In
17756 addition, remove all the old code that generated the assignments
17757 associated with the signature of the dispatch table and replace them
17758 by a call to the new subprogram Set_Signature.
17759 (Set_All_DT_Position): Change the algorithm because now we have a
17760 separate dispatch table associated with predefined primitive operations.
17761 (Expand_Interface_Conversion): In case of non-static offset_to_top
17762 add explicit dereference to get access to the object after the call
17763 to displace the pointer to the object.
17764 (Expand_Interface_Thunk): Modify the generation of the actual used
17765 in the calls to the run-time function Offset_To_Top to fulfil its
17767 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
17769 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17771 * exp_dist.adb (Copy_Specification): For access parameters, copy
17772 Null_Exclusion flag, which will have been set for stream subprograms
17775 2006-02-13 Pascal Obry <obry@adacore.com>
17777 * expect.c (__gnat_expect_portable_execvp): New implementation. The
17778 previous implementation was using the C runtime spawnve routine but
17779 the corresponding wait was using directly the Win32 API. This was
17780 causing some times a lock when waiting for an event using
17781 WaitForSingleObject in __gnat_waitpid. This new implementation uses
17782 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
17783 API fixes this problem.
17785 2006-02-13 Robert Dewar <dewar@adacore.com>
17787 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

17795 array reference that is an explicit dereference, mark the converted
17796 (packed) array reference as analyzed to prevent a forthcoming
17797 reanalysis from resetting its type to the original (non-packed) array
17800 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17801 Javier Miranda <miranda@adacore.com>
17802 Eric Botcazou <ebotcazou@adacore.com>
17804 * exp_util.ads, exp_util.adb (Find_Prim_Op,
17805 Is_Predefined_Primitive_Operation): When
17806 searching for the predefined equality operator, verify that operands
17807 have the same type.
17808 (Is_Predefined_Dispatching_Operation): Remove the code that looks
17809 for the last entity in the list of aliased subprograms. This code
17810 was wrong in case of renamings.
17811 (Set_Renamed_Subprogram): New procedure
17812 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
17813 Exp_Type constant computed when entering this subprogram.

17815 (OK_To_Do_Constant_Replacement): New function
17816 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
17817 (Side_Effect_Free): An attribute reference 'Input is not free of
17818 side effect, unlike other attributes that are functions. (from code
17820 (Remove_Side_Effects): Expressions that involve packed arrays or records
17821 are copied at the point of reference, and therefore must be marked as
17822 renamings of objects.
17823 (Is_Predefined_Dispatching_Operation): Return false if the operation is
17824 not a dispatching operation.
17827 (Remove_Side_Effects): Lift enclosing type conversion nodes for
17828 elementary types in all cases.

17833 task types when accessing to the corresponding record type.
17834 Remove '!' in warning message.
17836 2006-02-13 Olivier Hainque <hainque@adacore.com>
17838 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
17839 to avoid useless and space inefficient overalignments on targets where
17840 Max_Alignment is larger than 16.
17842 2006-02-13 Pascal Obry <obry@adacore.com>
17844 * g-catiio.adb (Sec_Number): New type used to compute the number of
17845 seconds since 1-1-1970.
17846 (Image) [Natural]: The parameter was an Integer, as we can't deal with
17847 negative numbers (years, months...) it is better to have a Natural here.
17849 (Image) [Number]: Change parameter from Long_Integer to Number.
17850 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
17851 overflow for dates past year 2038.
17853 2006-02-13 Matthew Heaney <heaney@adacore.com>
17855 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
17858 2006-02-13 Arnaud Charlet <charlet@adacore.com>
17860 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
17862 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
17863 finalization can occur normally.
17865 2006-02-13 Vincent Celier <celier@adacore.com>
17867 * gnatcmd.adb (Rules_Switches): New table
17868 (Add_To_Rules_Switches): New procedure
17869 (GNATCmd): For command CHECK, put all options following "-rules" in the
17870 Rules_Switches table. Append these -rules switches after the -cargs
17873 2006-02-13 Robert Dewar <dewar@adacore.com>
17875 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
17876 These two cases were generating incorrect output, and if this unit
17877 was built with checks on, generated a discriminant mismatch constraint
17880 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17881 Robert Dewar <dewar@adacore.com>
17883 * lib-xref.adb (Get_Type_Reference): For a private type whose full
17884 view is an array type, indicate the component type as well, for
17885 navigation purposes.
17886 (Generate_Reference): Don't consider array ref on LHS to be a case
17887 of violating pragma Unreferenced.
17888 Do not give Ada 2005 warning except on real reference.

17892 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
17893 main source, add switch -mdebug-main=_ada_ so that the executable can
17894 be debugged by the standard VMS debugger.
17895 (Gnatmake): Set No_Main_Subprogram to True when there is no main
17896 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
17897 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
17898 of the last source, as the binding and linking phases are never
17900 Set all executable obsolete when rebuilding a library.
17902 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
17905 2006-02-13 Javier Miranda <miranda@adacore.com>
17908 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
17909 code to improve the error message reported when the program has
17910 declarations of abstract interface types and it is not compiled with
17911 the -gnat05 switch.
17912 (P_Access_Definition): Reorganize the code to improve the error
17913 message reported when the new Ada 2005 syntax for anonymous
17914 access types is used and the program is not compiled with the

17986 No_Return procedure with procedure that is not No_Return
17987 (Check_Dispatching_Call): Suppress the check for an abstract operation
17988 when the original node of an actual is a tag-indeterminate attribute
17989 call, since the attribute, which must be 'Input, can never be abstract.
17990 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
17991 call to the Input attribute (even when rewritten).
17992 (Propagate_Tag): Augment comment to indicate the possibility of a call
17993 to an Input attribute.
17995 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
17996 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.

18009 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
18010 handles default-initialized components to keep separate the management
18011 of this feature but also avoid the unrequired resolution and
18012 expansion of components that do not have partially initialized
18014 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
18015 (Check_Bounds): Likewise.
18016 (Check_Length): Likewise.
18018 2006-02-13 Javier Miranda <miranda@adacore.com>
18019 Ed Schonberg <schonberg@adacore.com>
18021 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
18022 abstract interface type call analyze_and_resolve to expand the type
18023 conversion into the corresponding displacement of the
18024 reference to the base of the object.
18025 (Eval_Attribute, case Width): For systems where IEEE extended precision
18026 is supported, the maximum exponent occupies 4 decimal digits.
18027 (Accessibility_Message): Add '\' in 2-line warning message.
18028 (Resolve_Attribute): Likewise.
18029 (case Attribute_Access): Significantly revise checks
18030 for illegal access-to-subprogram Access attributes to properly enforce
18031 the rules of 3.10.2(32/2).
18032 Diagnose use of current instance with an illegal attribute.
18034 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
18036 (Enclosing_Generic_Unit): New function to return a node's innermost
18037 enclosing generic declaration node.
18038 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
18039 (Type_Access_Level): The accessibility level of anonymous acccess types
18040 associated with discriminants is that of the current instance of the
18041 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
18042 (Compile_Time_Constraint_Error): Handle case of conditional expression.
18043 (Kill_Current_Values_For_Entity): New function
18044 (Enter_Name): Change formal type to Entity_Id

18047 Ed Schonberg <schonberg@adacore.com>
18048 Gary Dismukes <dismukes@adacore.com>
18050 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
18051 Analyze_Compilation_Unit.
18052 Detect and warn on redundant with clauses detected in a package spec
18053 and/or body when -gnatwr is used.

18058 unused packages can be properly generated
18059 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
18060 has Error_Posted set. Prevent infinite loops in illegal programs.
18061 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
18062 to the point of the error test requiring the current unit to be private.
18063 This ensures that private with clauses are not exempted from the basic
18064 checking for being a descendant of the same library unit parent as a
18065 withed private descendant unit.
18066 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
18067 handle private with clauses properly, as well as to account for cases
18068 where the withed unit is a public descendant of a private ancestor
18069 (in which case the current unit must be a descendant of the private
18070 ancestor's parent). The spec comments were updated accordingly. Also,
18071 the old error message in this subprogram was replaced with error
18072 messages that mirror the errors tested and reported by
18073 Check_Private_Child_Unit.
18074 Parameter and variable names improved for readability.
18075 (Install_Limited_Context_Clauses): Remove test for a withed unit being
18076 private as the precondition for calling
18077 Check_Private_Limited_Withed_Unit since that subprogram has been
18078 revised to test public units as well as private units.

18083 Javier Miranda <miranda@adacore.com>
18085 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
18086 that Scope_Stack.First = 1.
18087 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18088 were not always properly handled previously.
18089 (Formal_Entity): Complete rewrite, to handle properly some complex case
18090 with multiple levels of parametrization by formal packages.
18091 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
18092 to the corresponding derived type declaration for proper semantics.
18094 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
18095 (Check_Component): Enforce restriction on components of
18096 unchecked_unions: a component in a variant cannot contain tasks or
18098 (Unchecked_Union): Allow nested variants and multiple discriminants, to
18100 Add pragma Ada_2005 (synonym for Ada_05)
18101 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18102 were not always properly handled previously.
18103 Document that pragma Propagate_Exceptions has no effect
18104 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
18105 (Set_Convention_From_Pragma): Check that if a convention is
18106 specified for a dispatching operation, then it must be
18107 consistent with the existing convention for the operation.
18108 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
18109 longer required to specify an vtable-ptr component in the record. For
18110 compatibility reasons we leave the support for the previous definition.
18111 (Analyze_Pragma, case No_Return): Allow multiple arguments
18113 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
18114 non-overrideen inherited operation with a controlling result as
18115 illegal only its implicit declaration comes from the derived type
18116 declaration of its result's type.
18117 (Check_Possible_Deferred_Completion): Relocate the object definition
18118 node of the subtype indication of a deferred constant completion rather
18119 than directly analyzing it. The analysis of the generated subtype will
18120 correctly decorate the GNAT tree.
18121 (Record_Type_Declaration): Check whether this is a declaration for a
18122 limited derived record before analyzing components.
18123 (Analyze_Component_Declaration): Diagnose record types not explicitly
18124 declared limited when a component has a limited type.
18125 (Build_Derived_Record_Type): Code reorganization to check if some of
18126 the inherited subprograms of a tagged type cover interface primitives.
18127 This check was missing in case of a full-type associated with a private
18129 (Constant_Redeclaration): Check that the subtypes of the partial and the
18130 full view of a constrained deferred constant statically match.
18131 (Mentions_T): A reference to the current type in an anonymous access
18132 component declaration must be an entity name.
18133 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
18134 class_wide type to refer to full type, not to the incomplete one.
18135 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
18136 available. Required to give support to the certified run-time.
18137 (Analyze_Component_Declaration): In case of anonymous access components
18138 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
18139 (Process_Discriminants): For an access discriminant, use the
18140 discriminant specification as the associated_node_for_itype, to
18141 simplify accessibility checks.
18143 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18144 Javier Miranda <miranda@adacore.com>
18146 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
18147 abstract interpretations on an operator, remove interpretations that
18148 yield Address or a type derived from it, if one of the operands is an
18150 (Try_Object_Operation.Try_Primitive_Operation,
18151 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
18152 location when creating the new reference to a primitive or class-wide
18153 operation as a part of rewriting a subprogram call.
18154 (Try_Primitive_Operations): If context requires a function, collect all
18155 interpretations after the first match, because there may be primitive
18156 operations of the same type with the same profile and different return
18157 types. From code reading.
18158 (Try_Primitive_Operation): Use the node kind to choose the proper
18159 operation when a function and a procedure have the same parameter
18161 (Complete_Object_Operation): If formal is an access parameter and prefix
18162 is an object, rewrite as an Access reference, to match signature of
18163 primitive operation.
18164 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
18165 by an expanded name with prefix Standard, when the operands are of an
18166 anonymous access type.
18167 (Remove_Abstract_Operations): If the operation is abstract because it is
18168 inherited by a user-defined type derived from Address, remove it as
18169 well from the set of candidate interpretations of an overloaded node.
18170 (Analyze_Membership_Op): Membership test not applicable to cpp-class
18173 2006-02-13 Bob Duff <duff@adacore.com>
18175 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
18176 redundant use clauses.
18177 In particular, if the scope of two use clauses overlaps, but one is not
18178 entirely included in the other, we should not warn. This can happen
18179 with nested packages.
18180 (Analyze_Subprogram_Renaming): Protect the compiler against previously
18181 reported errors. The bug was reported when the compiler was built
18182 with assertions enabled.
18183 (Find_Type): If the node is a 'Class reference and the prefix is a
18184 synchronized type without a corresponding record, return the type
18187 2006-02-13 Javier Miranda <miranda@adacore.com>
18189 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
18190 if this is the full-declaration associated with a private declaration
18191 that implement interfaces, then the private type declaration must be
18193 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
18194 as aliased. The use of the 'access attribute is not available for such
18195 object (for this purpose the object should be explicitly marked as
18196 aliased, but being an anonymous type this is not possible).
18198 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18199 Robert Dewar <dewar@adacore.com>
18201 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
18202 compilation unit is an elaboration scope.
18203 (Add_Task_Proc): Add '\' in 2-line warning message.
18204 (Activate_All_Desirable): Deal with case of unit with'ed by parent
18206 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18207 Javier Miranda <miranda@adacore.com>
18209 * sem_type.adb (Write_Overloads): Improve display of candidate
18211 (Add_One_Interp): Do not add to the list of interpretations aliased
18212 entities corresponding with an abstract interface type that is an
18213 immediate ancestor of a tagged type; otherwise we have a dummy
18214 conflict between this entity and the aliased entity.
18215 (Disambiguate): The predefined equality on universal_access is not
18216 usable if there is a user-defined equality with the proper signature,
18217 declared in the same declarative part as the designated type.
18218 (Find_Unique_Type): The universal_access equality operator defined under
18219 AI-230 does not cover pool specific access types.
18220 (Covers): If one of the types is a generic actual subtype, check whether
18221 it matches the partial view of the other type.
18223 2006-02-13 Thomas Quinot <quinot@adacore.com>
18225 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
18226 line. This is necessary to allow In_Extended_Main_Unit to provide
18227 correct results for itypes while writing out expanded source.
18228 (Close_File): No need to update the source_index_table here since it's
18229 now done for each line.
18231 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18232 Robert Dewar <dewar@adacore.com>
18234 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
18235 preserve the source unit where the itype is declared, and prevent a
18237 (Note_Implicit_Run_Time_Call): New procedure
18238 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
18241 * sprint.ads: Document use of $ for implicit run time routine call
18243 2006-02-13 Quentin Ochem <ochem@adacore.com>
18245 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
18248 2006-02-13 Bob Duff <duff@adacore.com>
18250 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
18251 Scan_Unsigned, so we do not scan leading blanks and sign twice.
18252 Integer'Value("- 5") and Integer'Value("-+5") now correctly
18253 raise Constraint_Error.
18255 * s-vallli.adb (Scan_Long_Long_Integer): Call
18256 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
18257 do not scan leading blanks and sign twice.
18258 Integer'Value("- 5") and Integer'Value("-+5") now correctly
18259 raise Constraint_Error.
18261 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
18262 Scan_Long_Long_Unsigned): Split out most of the processing from
18263 Scan_Long_Long_Unsigned out into
18264 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
18265 This prevents scanning leading blanks and sign twice.
18266 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
18269 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
18270 out most of the processing from Scan_Unsigned out into
18271 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
18272 This prevents scanning leading blanks and sign twice.
18274 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
18275 use with Modular'Value attribute.
18276 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
18279 2006-02-13 Robert Dewar <dewar@adacore.com>
18281 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value

18286 (PPC VxWorks): Likewise.
18287 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
18288 (forced_callee): Make non-inlinable and non-pure.
18289 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

18405 Ada bind file prefix on VMS from b$ to b__.
18407 * gnatlink.adb (Process_Args): Call Add_Src_Search_Dir for -I in
18408 --GCC so that Get_Target_Parameters can find system.ads.
18409 (Gnatlink): Call Get_Target_Parameters in mainline.
18410 Initialize standard packages for Targparm.
18411 Change some Hostparm.OpenVMS checks to Targparm.OpenVMS_On_Target.

18430 * Makefile.in: add support for vxworks653 builds
18431 (../../vxaddr2line): gnatlink with targext.o.
18432 (TOOLS_LIBS): Move targext.o to precede libgnat.
18433 (init.o, initialize.o): Minor clean up in dependencies.

18474 * a-taster.ads, a-taster.adb: New files.
18476 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
18477 link to the version that does nothing. This way the task termination
18478 routine is not executed twice for the environment task when finishing
18479 because of an unhandled exception.
18481 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
18482 handler because of an unhandled exception.
18484 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
18485 System.Tasking.Utilities instead of that in System.Tasking.Stages.
18487 * s-finimp.adb (initialization code): Modify the soft link for the
18488 finalization of the global list instead of Adafinal.
18490 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
18491 non-tasking version of the soft link for task termination. We do
18492 nothing since if we are using the non-tasking version it
18493 means that the task termination functionality is not used.
18494 (Null_Finalize_Global_List): Add this null version for the procedure
18495 in charge of finalizing the global list for controlled objects.
18496 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
18497 instead for handling run-time termination in a more flexible way.
18498 (Adafinal_NT): This new procedure will take care of finalizing the
18499 global list for controlled objects if needed, but no tasking
18502 * s-tarest.adb (Task_Lock): Do not try to lock again the
18503 Global_Task_Lock if we already own it. Otherwise, we get blocked in
18504 some run-time operations.
18505 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
18506 until all nested locks have been released.
18507 (Task_Wrapper): Call the fall-back task termination handler. It
18508 applies to all tasks but the environment task.
18509 (Finalize_Global_Tasks): Add the call for the task termination
18510 procedure for the environment task.
18511 (Task_Wrapper): suppress warnings around declaration of
18512 Secondary_Stack_Address.
18514 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
18515 moved to the Common_ATCB record.
18516 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
18517 Common_ATCB record.
18518 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
18519 Common_ATCB record.
18521 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
18522 Fall_Back_Handler, and Specific_Handler.
18524 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
18525 defined in Ada.Task_Termination, to avoid circular dependencies.
18526 (Termination_Handler): Redefine this type here, alredy defined in
18527 Ada.Task_Termination, for avoiding circular dependencies.
18528 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
18529 for storing task termination handlers. In addition,
18530 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
18531 Common_ATCB because it is used by both the regular and the restricted
18533 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
18534 Common_ATCB because it is used by both the regular and the restricted
18536 (Common_ATCB): Added a dynamic task analyzer field.
18538 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
18539 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
18540 (Task_Wrapper): Call the task termination handler. It applies to all
18541 tasks but the environment task.
18542 (Finalize_Global_Tasks): Call the task termination procedure for the
18543 environment task. The call to Finalize_Global_List is now performed
18544 using the soft links mechanism.
18545 (Task_Wrapper): added dynamic stack analysis.
18547 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
18548 potentially blocking operations has been moved from
18549 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
18550 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
18551 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
18552 this run-time check.

18603 (Displace): New subprogram that displaces the pointer to the object
18604 to reference one of its secondary dispatch tables.
18605 (IW_Membership): Modified to use the new table of interfaces.
18606 (Inherit_TSD): Modified to use the new table of interfaces.

18626 record component containing the tag of the secondary dispatch table we
18627 have to use the Offset_To_Top run-time function to get this information;
18628 otherwise if the pointer to the base of the object has been displace
18629 we get a wrong value if we use the 'position attribute.
18631 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
18632 all the calls to Expand_Interface_Thunk.

18667 RE_TK_Tagged, RE_TK_Task.
18669 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
18670 Init_Secondary_Tags_Internal to allow its use with interface types and
18671 also to generate the code for the new additional actual required
18672 by Set_Offset_To_Top.
18673 (Build_Init_Statements): In case of components associated with abstract
18674 interface types there is no need to generate a call to its IP.

18686 properly protected objects and attach handler in the case of the
18687 restricted profile.

18701 pointer initialization values. Make a SAVE_EXPR instead. Add comments
18702 about the use and expansion of SAVE_EXPRs in the various possible
18703 renaming handling cases.
18704 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
18705 abusing DECL_FCONTEXT.

18875 are implemented by the ancestors.
18876 (Derived_Type_Declaration): If the parent of the full-view is an
18877 interface perform a transformation of the tree to ensure that it has
18878 the same parent than the partial-view. This simplifies the job of the
18879 expander in order to generate the correct object layout, and it is
18880 needed because the list of interfaces of the full-view can be given in
18882 (Process_Full_View): The parent of the full-view does not need to be
18883 a descendant of the parent of the partial view if both parents are
18885 (Analyze_Private_Extension_Declaration): If declaration has an explicit
18886 "limited" the parent must be a limited type.

18963 attributes are visible at the point of the subprogram declaration.
18964 For Ada 2005, the error message is modified to indicate that the

19224 may be platform-defined macros.
19225 For VxWorks, generate the OK and ERROR values.
19226 New constants giving the sizes of the components of C struct timeval.

19238 deal with different cases of static and dynamic elaboration checks (all
19239 checks does not count in the first case, but does in the second).

19245 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
19246 elementary types using the operator in standard. It is cleaner not to
19247 modify the programmers intent, especially in the case of floating-point.
19248 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
19249 it did not matter because we always rewrote a/=b to not(a=b).
19250 (Expand_Allocator_Expression): For an allocator expression whose nominal
19251 subtype is an unconstrained packed type, convert the expression to its
19252 actual constrained subtype.
19253 Implement warning for <= or >= where < or > not possible
19254 Fix to Vax_Float tests (too early in many routines, causing premature
19255 Vax_Float expansions.
19257 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
19258 to be used with packages and generic packages as well as with

19261 of pragma Suppress (All_Checks)
19262 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
19263 a string literal for precise control over warnings.

19273 Allow optional = after -gnatm
19274 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
19275 longer sets Elaboration_Checks.
19276 Code to set warning mode moved to Sem_Warn
19277 so that it can be shared by pragma processing.
19279 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
19282 * s-taprop-solaris.adb:
19283 Change some <= to =, to avoid new warning

19291 * exp_vfpt.adb: Handle /= case
19292 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
19293 so that we do not get duplicate scaling for fixed point conversions.

19297 2005-11-14 Matthew Gingell <gingell@adacore.com>
19299 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
19300 Increase default priority on Lynx from 15 to 17, and meet the Ada
19301 requirement that Default_Priority be ((Priority'First +
19302 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

19404 we are not defining the type.
19405 <E_Record_Type>: Likewise.
19406 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
19407 to get advantage of the new maybe_stabilize_reference interface, to
19408 ensure that what we reference is indeed stabilized instead of relying
19409 on assumptions on what the stabilizer does.
19410 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
19411 type imported through a limited_with clause, use its non-limited view.
19412 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
19414 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
19415 of #if sections + explicit comparisons of convention identifiers.
19416 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
19417 before early-returning for certain types when code generation is
19419 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
19420 nullification of gnu_expr we do for objects with address clause and
19421 that we are not defining.
19422 (elaborate_expression_1): Do not create constants when creating
19423 variables needed by the debug info: the dwarf2 writer considers that
19424 CONST_DECLs is used only to represent enumeration constants, and emits
19426 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
19427 object with an address clause into an indirect reference, drop the
19428 initializing expression.
19430 (STACK_CHECK_BUILTIN): Delete.
19431 (STACK_CHECK_PROBE_INTERVAL): Likewise.

19439 if there is an actual subtype provided by the front-end, use that
19440 subtype to build an actual type with bounds template.
19441 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
19442 is provided by the front-end, use that subtype to compute the size of
19443 the deallocated object.
19444 (gnat_to_gnu): When adding a statement into an elaboration procedure,
19445 check for a potential violation of a No_Elaboration_Code restriction.
19446 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
19447 with extra arguments to control whether to recurse through non-values
19448 and to let the caller know if the stabilization has succeeded.

19450 maybe_stabilize, for common uses without restriction on lvalues and
19451 without need to check for the success indication.
19452 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
19453 pass false instead of 0 as the FORCE argument which is a bool.
19454 (Identifier_to_gnu): Remove checks ensuring that an renamed object
19455 attached to a renaming pointer has been properly stabilized, as no such
19456 object is attached otherwise.
19457 (call_to_gnu): Invoke create_var_decl to create the temporary when the
19458 function uses the "target pointer" return mechanism.
19459 Reinstate conversion of the actual to the type of the formal
19460 parameter before any other specific treatment based on the passing
19461 mechanism. This turns out to be necessary in order for PLACEHOLDER
19462 substitution to work properly when the latter type is unconstrained.
19464 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
19466 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
19467 with extra arguments to control whether to recurse through non-values
19468 and to let the caller know if the stabilization has succeeded.
19470 * utils2.c (gnat_build_constructor): Only sort the fields for possible
19471 static output of record constructor if all the components are constant.
19472 (gnat_build_constructor): For a record type, sort the list of field
19473 initializers in increasing bit position order.
19474 Factor common code to build a storage type for an unconstrained object
19475 from a fat or thin pointer type and a constrained object type.
19476 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
19477 types variants, and process special cases of VIEW_CONVERT expressions
19478 as their NOP_EXPR counterpart to ensure we get to the
19479 CORRESPONDING_VARs associated with CONST_DECls.
19480 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
19481 on the right-hand side.
19483 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
19485 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
19486 are converting back to its original type.
19487 (convert) <JM input>: Fallthrough regular conversion code instead of
19488 extracting the object if converting to a type variant.
19489 (create_var_decl): When a variable has an initializer requiring code
19490 generation and we are at the top level, check for a potential violation
19491 of a No_Elaboration_Code restriction.
19492 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
19493 SIZE and SIZE_UNIT which we need for later back-annotations.
19494 * utils.c: (convert) <STRING_CST>: Remove obsolete code.
19495 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
19496 is an unchecked union.
19497 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
19498 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
19499 main variant, just replace the VIEW_CONVERT_EXPR.

19685 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
19686 'Terminated for task interface class-wide objects. Generate a call to
19687 the predefined dispatching routine used to retrieve the _task_id from

19748 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

19768 attribute of the N_Free_Statement.
19769 Generate itype for classwide designated object in both cases of
19770 user-specified storage pool: specific and class-wide, not only in the
19772 Raise CE when trying to set a not null access type object to null.

19990 (Check_Generic_Child_Unit): Within an inlined call, the only possible
19991 instantiation is Unchecked_Conversion, for which no parents are needed.
19992 (Inline_Instance_Body): Deinstall and record the use_clauses for all
19993 parent scopes of a scope being removed prior to inlining an instance
19995 (Analyze_Package_Instantiation): Do not perform front-end inlining when
19996 the current context is itself an instance within a non-instance child
19997 unit, to prevent scope stack errors.
19998 (Save_References): If the node is an aggregate that is an actual in a
19999 call, rewrite as a qualified expression to preserve some type
20000 information, to resolve possible ambiguities in the instance.
20001 (Instance_Parent_Unit): New global variable to record the ultimate
20002 parent unit associated with a generic child unit instance (associated
20003 with the existing Parent_Unit_Visible flag).

20009 it's not a top-level unit, and only do this if Instance_Parent_Unit is
20010 not already set. Replace test of Is_Child_Unit with test of parent's
20011 scope against package Standard. Add comments and a ??? comment.
20012 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
20013 on a child instance parent to test that the parent equals

20028 * sem_ch3.ads, sem_ch3.adb (Build_Discriminal): Add link to original
20030 (Build_Private_Derived_Type): The entity of the created full view of the
20031 derived type does not come from source. If after installing the private
20032 declarations of the parent scope the parent is still private, use its
20033 full view to construct the full declaration of the derived type.
20034 (Build_Derived_Record_Type): Relax the condition that controls the
20035 execution of the check that verifies that the partial view and
20036 the full view agree in the set of implemented interfaces. In
20037 addition, this test now only takes into account the progenitors.
20038 (Derive_Interface_Subprograms): No need to derive subprograms
20039 of ancestors that are interfaces.

20044 view is a transitive derivation of the ancestor of the partial view.
20045 (Process_Full_View): Rename local subprogram Find_Interface_In_
20046 Descendant to Find_Ancestor_Interface to leave the code more clear.
20047 Remove wrong code that avoids the generation of an error message
20048 when the immediate ancestor of the partial view is an interface.
20049 In addition some minor reorganization of the code has been done to
20050 leave it more clear.
20051 (Analyze_Type_Declaration): If type has previous incomplete tagged
20052 partial view, inherit properly its primitive operations.

20065 and derived protected types, the parent may be an interface that must
20066 be included in the interface list.
20067 (Access_Definition): If the designated type is an interface that may
20068 contain tasks, create Master_Id for it before analyzing the expression
20069 of the declaration, which may be an allocator.
20070 (Record_Type_Declaration): Set properly the interface kind, for use
20071 in allocators, the creation of master id's for task interfaces, etc.

20080 subprogram declaration.
20081 Change name Is_Package to Is_Package_Or_Generic_Package
20082 (Process_Formals): A non null qualifier on a non null named access
20083 type is not an error, and is a warning only if Redundant_Constructs

20094 package associated with a generic instance or formal package, the
20095 private declarations of the parent must be installed (by calling new
20096 procedure Install_Parent_Private_Declarations).
20097 Change name Is_Package to Is_Package_Or_Generic_Package
20098 (Preserve_Full_Attributes): For a synchronized type, the corresponding
20099 record is absent in a generic context, which does not indicate a

20104 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
20105 not try to rewrite a renamed stream attribute, because the operations
20106 on the type may not have been generated.
20107 Handle properly a renaming_as_body generated for a stream operation
20108 whose default is abstract because the object type itself is abstract.
20109 (Find_Type): If the type is incomplete and appears as the prefix of a
20110 'Class reference, it is tagged, and its list of primitive operations
20111 must be initialized properly.
20112 (Chain_Use_Clauses): When chaining the use clauses that appear in the
20113 private declaration of a parent unit, prior to compiling the private
20114 part of a child unit, find on the scope stack the proper parent entity
20115 on which to link the use clause.
20116 (Note_Redundant_Use): Emit a warning when a redundant use clause is
20118 (Analyze_Object_Renaming): An attribute reference is not a legal object
20119 if it is not a function call.

20136 a procedure call is used as a select statement trigger and is not an
20137 entry renaming or a primitive of a limited interface.
20138 (Valid_Conversion): If the operand has a single interpretation do not
20139 remove address operations.
20140 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
20141 statement to inhibit warning.
20142 (Resolve_Unary_Op): Do not produce a warning when
20143 processing an expression of the form -(A mod B)
20144 Use Universal_Real instead of Long_Long_Float when we need a high
20145 precision float type for the generated code (prevents gratuitous
20146 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
20147 (Resolve_Concatenation_Arg): Improve error message when argument is an
20148 ambiguous call to a function that returns an array.
20149 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

20733 (Expand_Allocator_Expression): Add tests for suppression of the AI-344
20734 check for proper accessibility of the operand of a class-wide allocator.
20735 The check can be left out if checks are suppressed or if the expression
20736 has a specific tagged type whose level is known to be safe.

21089 2005-09-01 Robert Dewar <dewar@adacore.com>
21091 * checks.adb (Check_Needed): New procedure, deals with removing checks
21092 based on analysis of short-circuited forms. Also generates warnings for
21093 improper use of non-short-circuited forms.
21096 2005-09-01 Robert Dewar <dewar@adacore.com>
21098 * a-ztexio.adb, a-textio.adb, a-witeio.adb: Replace bad range checks
21101 2005-09-01 Robert Dewar <dewar@adacore.com>
21103 * errout.ads, errout.adb (Fix Error_Msg_F): Fix implementation to meet

21107 (conditional warning).
21108 * sem_elab.adb, prj-dect.adb, erroutc.ads, err_vars.ads
21109 (Error_Msg_Warn): New variable for < insertion char.
21110 * prj-nmsc.adb: Implement new errout insertion char < (conditional
21112 (Check_For_Source): Change value of Source_Id only after the current
21113 source has been dealt with.
21115 2005-09-01 Robert Dewar <dewar@adacore.com>
21116 Doug Rupp <rupp@adacore.com>
21118 * exp_attr.adb: Handle vax fpt for 'Valid attribute

21124 Hristian Kirtchev <kirtchev@adacore.com>
21125 Javier Miranda <miranda@adacore.com>
21127 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
21128 from object notation, the original node is unanalyzed and carries no
21129 semantic information, so that accessiblity checks must be performed on
21130 the type of the actual itself.
21131 (Expand_N_Subprogram_Declaration): Change last actual parameter for
21132 compatibility with Build_Protected_Sub_Specification.
21133 (Check_Overriding_Inherited_Interfaces): Add suport to handle
21134 overloaded primitives.
21135 (Register_Interface_DT_Entry): Use the new name of the formal
21136 the the calls to Expand_Interface_Thunk
21138 * exp_dbug.ads: Augment comments on encoding of protected types to
21139 include the generation of dispatching subprograms when the type
21140 implements at least one interface.
21142 * lib.ads: Extend information in Load_Stack to include whether a given
21143 load comes from a Limited_With_Clause.
21145 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
21146 whether a potential circularity is harmless, because it includes units
21147 loaded through a limited_with clause. Extends previous treatment which
21148 did not handle properly arbitrary combinations of limited and
21149 non-limited clauses.
21151 2005-09-01 Nicolas Setton <setton@adacore.com>
21153 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
21154 to be encoded as typ___XBLU_lowerbound__upperbound instead of
21155 typ___XB_lowerbound__upperbound.
21157 2005-09-01 Thomas Quinot <quinot@adacore.com>
21159 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
21160 dummy access formal for RACW/RAS TypeCode TSS.
21161 (Build_TypeCode_Call): Do not generate dummy null access actual for
21162 calls to the TypeCode TSS.
21164 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21166 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
21167 fully qualified name, to distinguish instances with the same local name.
21169 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
21172 2005-09-01 Robert Dewar <dewar@adacore.com>

21177 2005-09-01 Jerome Lambourg <lambourg@adacore.com>
21179 * g-expect.adb (Non_Blocking_Spawn): Initialize the filters field to
21180 (Free): New deallocation procedure for filter elements
21181 (Close): Deallocate any existing filter for the concerned connection
21183 2005-09-01 Laurent Pautet <pautet@adacore.com>
21185 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
21186 position set is provided, we compute one in order to reduce the maximum
21187 length of the keys. This computation first selects a character
21188 position between 1 and the minimum length of the keys in order to
21189 avoid reducing one of the keys to an empty string.
21190 (Initialize, Compute): When the ratio V to K is too low, the algorithm
21191 does not converge. The initialization procedure now comes with a
21192 maximum number of iterations such that when exceeded, an exception is
21193 raised in Compute. The user can initialize this ratio to another value
21195 Reformating and updated headers.
21197 2005-09-01 Javier Miranda <miranda@adacore.com>
21199 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
21200 that given an entity T creates and returns an Itype that duplicates the
21201 contents of T. The returned Itype has the null-exclusion
21202 attribute set to True, and its Etype attribute references T
21203 to keep the association between the two entities.
21204 Update copyright notice
21206 * sem_aggr.adb (Check_Can_Never_Be_Null,
21207 Aggregate_Constraint_Checks, Resolve_Aggregate,
21208 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
21210 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

21213 Robert Dewar <dewar@adacore.com>
21214 Hristian Kirtchev <kirtchev@adacore.com>

21223 plus null exclusions. Call Set_Result_Definition instead of
21226 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
21227 (P_Access_Type_Definition): Add parsing for an anonymous access result
21228 subtype, plus parsing for null exclusions. Call Set_Result_Definition
21229 instead of Set_Subtype_Mark.
21231 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
21232 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
21233 (Result_Definition): New function for N_Function_Specifications.
21234 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
21235 N_Function_Specification.
21236 (Set_Null_Exclusion_Present): Allow this flag for
21237 N_Function_Specification.
21238 (Set_Result_Definition): New procedure for N_Function_Specifications.
21239 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
21240 and N_Function_Specification.
21242 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
21243 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
21244 Add support for LIMITED NEW for Ada 2005 AI-419
21245 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
21246 syntax for anonymous access results.
21247 Replace Subtype_Mark field by Result_Definition in
21248 N_Function_Specification and N_Access_Definition specs.
21249 Add Null_Exclusion_Present to spec of N_Function_Specification.
21250 (Result_Definition): New function for N_Function_Specification and
21251 N_Access_Function_Definition.
21252 (Set_Result_Definition): New procedure for N_Function_Specification and
21253 N_Access_Function_Definition.
21255 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
21256 Result_Definition for cases of N_Access_Function_Definition and
21257 N_Function_Specification.
21258 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
21260 2005-09-01 Vincent Celier <celier@adacore.com>
21262 * lib-writ.adb: Update Copyright notice
21263 (Write_With_Lines): On platforms where file names are case-insensitive,
21264 record the file names in lower case.
21265 (Write_ALI): For D lines, on platforms where file names are
21266 case-insensitive, record the file names in lower case.
21268 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21269 Emmanuel Briot <briot@adacore.com>
21271 * lib-xref.adb (Output_Overridden_Op): Display information on
21272 overridden operation.
21274 * lib-xref.ads: Add documentation on overridden operations.
21276 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
21279 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
21280 overriding entity information.
21282 2005-09-01 Vincent Celier <celier@adacore.com>
21284 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
21285 including those that are inherited.
21287 2005-09-01 Robert Dewar <dewar@adacore.com>
21289 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
21291 * par-prag.adb: Implement new pragma Debug_Policy
21293 * sem_prag.adb Implement new pragma Debug_Policy
21294 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
21295 Component_Size attribute specification. Give warning for ignored pragma
21298 * snames.h, snames.ads, snames.adb: Introduce entries in
21299 Preset_Names for Name_Disp_Asynchronous_Select,
21300 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
21301 Name_Disp_Timed_Select.
21302 New pragma Debug_Policy
21304 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
21306 Switch -gnata also sets Debug_Pragmas_Enabled
21308 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
21309 handle an explicit -gnata when compiling predefined files.
21311 2005-09-01 Vincent Celier <celier@adacore.com>
21313 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
21314 directories of projects that have no Ada sources.
21316 2005-09-01 Robert Dewar <dewar@adacore.com>
21318 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
21319 (makes a difference for wide characters)
21321 * widechar.adb, widechar.ads:
21322 Add Wide_Char_Byte_Count feature to count chars vs bytes
21324 2005-09-01 Thomas Quinot <quinot@adacore.com>
21325 Ed Schonberg <schonberg@adacore.com>
21326 Robert Dewar <dewar@adacore.com>
21328 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
21329 'Address attribute reference with an overloaded prefix, use the
21330 location of the prefix (not the location of the attribute reference) as
21331 the error location.
21332 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
21333 a function renaming thereof, is a valid prefix for 'Size (where it is
21334 intepreted as a function call).
21335 (Statically_Denotes_Entity): New predicate to determine whether the
21336 prefix of an array attribute can be considered static.
21339 (Eval_Attr): Fix failure to evaluate Component_Size for
21340 unconstrained arrays (resulted in wrong value in packed case, since
21341 back end cannot handle this case)
21343 2005-09-01 Robert Dewar <dewar@adacore.com>
21345 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
21346 error msgs for most common cases.
21347 Use new errout insertion char < (conditional warning)
21349 2005-09-01 Javier Miranda <miranda@adacore.com>
21350 Ed Schonberg <schonberg@adacore.com>
21352 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
21353 become local to the whole package.
21354 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
21355 the package was already analyzed the new algorithm "replaces" the
21356 real entities by the shadow ones. This is required to ensure that
21357 the order of these entities in the homonym chains does not change;
21358 otherwise we can have undefined references at linking time because
21359 in case of conflicts the external name of the entities will have
21360 a suffix that depends on the order of the entities in the chain.
21361 (Remove_Limited_With_Clause): Complementary code that completes the
21362 new algorithm and replaces the shadow entities by the real ones.
21363 (Install_Limited_Withed_Unit): When unchaining entities before the
21364 installation of the shadow entities, only regular entities of the
21365 public part must be taken into account. This is required to
21366 keep this routine in synch with the work done by Remove_Limited_
21368 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
21369 even if unit is analyzed, because the analysis of the unit is
21370 idempotent in any case, and the limited view of the unit may have to
21371 be installed for proper visibility.
21372 (Expand_Limited_With_Clause): Even if the unit in the implicit
21373 with_clause has been analyzed already, a limited view of the package
21374 must be built for the current context, if it does not exist yet.
21376 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21377 Javier Miranda <miranda@adacore.com>
21378 Gary Dismukes <dismukes@adacore.com>
21380 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
21381 defining entity for the instance body, make a new defining identifier
21382 rather than copying the entity of the spec, to prevent accidental
21383 sharing of the entity list.
21384 (Check_Private_View): When exchanging views of private types, build the
21385 list of exchanged views as a stack, to ensure that on exit the exchanges
21386 are undone in the proper order.
21387 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
21388 Restore the compilation environment in case of instantiation_error.
21389 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
21390 for an anonymous access result.
21391 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
21392 (Formal_Entity): Handle properly the case of a formal package that
21393 denotes a generic package renaming.
21395 2005-09-01 Thomas Quinot <quinot@adacore.com>
21397 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
21398 clause if the array aggregate is surrounded by parentheses.
21400 2005-09-01 Cyrille Comar <comar@adacore.com>
21401 Gary Dismukes <dismukes@adacore.com>
21402 Ed Schonberg <schonberg@adacore.com>
21403 Javier Miranda <miranda@adacore.com>
21405 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
21407 to check if a type is Constrained in cases related to code generation
21408 (rather than semantic checking) since otherwise we do not generate
21409 similar code for mutable private types depending if their
21410 discriminants are visible or not.
21411 (Check_Abstract_Overriding): Do not complain about failure to override
21412 the primitive operations used in dispatching selects since they will
21413 always be overriden at the freeze point of the type.
21414 (Access_Definition): Separate out handling for resetting the scope
21415 of an anonymous access function result type. Retrieve the scope
21416 of the associated function rather than using Current_Scope, which
21417 does not have a consistent value (depends on whether we're in the
21418 middle of analyzing formal parameters). Add ??? comment about
21419 finding a cleaner way to handle the special cases of scope setting.
21420 (Process_Incomplete_Dependents): A protected operation is never a
21421 dispatching operation (only its wrapper may be).
21422 (Build_Derived_Record_Type): In case of tagged private types that
21423 implement interfaces add derivation of predefined primitive
21425 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
21426 by two parameters that are used in case of derivation from abstract
21427 interface types: No_Predefined_Prims is used to avoid the derivation
21428 of predefined primitives from the interface, and Predefined
21429 Prims_Only is used to complete the derivation predefined primitives
21430 in case of private tagged types implementing interfaces.
21431 Fix typo in comments
21432 (Find_Interface_In_Descendant): Protect the frontend against
21433 wrong code with large circularity chains.
21434 (Is_Private_Overriding): Add support for entities overriding interface
21435 subprograms. The test failed because Entities associated with overriden
21436 interface subprograms are always marked as hidden (and used to build
21437 the secondary dispatch table); in this case the overriden entity is
21438 available through the field abstract_interface_alias (cf. override_
21439 dispatching_operation)
21440 (Access_Definition): Set the scope of the type to Current_Scope for the
21441 case of a function with an anonymous access result type.
21442 (Access_Subprogram_Declaration): Handle creation of the type entity for
21443 an access-to-function type with an anonymous access result.
21444 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
21445 in handling for N_Access_Function_Definition.
21446 (Analyze_Subtype_Declaration): Modify the text of error message.
21447 (Derived_Type_Declaration): Modify the text of error message.
21448 (Process_Subtype): Modify the text of error message plus cleanup
21449 of one redundant error message.
21450 (Analyze_Component_Declaration): Code cleanup.
21451 (Analyze_Object_Declaration): Code cleanup.
21452 (Analyze_Subtype_Declaration): Propagate the null-exclusion
21453 attribute in case of access types. Code cleanup.
21454 (Array_Type_Declaration): Code cleanup.
21455 (Process_Discriminants): Create the new null-excluding itype
21456 if required. Code cleanup.
21457 (Process_Subtype): Create the new null-excluding itype if
21458 required. Code cleanup.
21459 (Build_Derived_Record_Type): Code cleanup to avoid calling
21460 twice the subprogram derive_subprograms in case of private
21461 types that implement interfaces. In this particular case the
21462 subprogram Complete_Subprograms_Derivation already does the
21463 job associated with the second call.
21465 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
21466 conversion to the full view when generating an operation for a
21467 discriminant whose type may currently be private.
21469 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21470 Javier Miranda <miranda@adacore.com>
21472 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
21473 V (Obj.F), the rewriting does not involve the indexed component, but
21474 only the selected component itself.
21475 Do not apply the transformation if the analyzed node is an actual of a
21476 call to another subprogram.
21477 (Complete_Object_Operation): Retain the entity of the
21478 dispatching operation in the selector of the rewritten node. The
21479 entity will be used in the expansion of dispatching selects.
21480 (Analyze_One_Call): Improve location of the error message associated
21482 (Analyze_Selected_Component): No need to resolve prefix when it is a
21483 function call, resolution is done when parent node is resolved, as
21485 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
21486 when attempting to resolve a call transformed from its object notation.
21487 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
21488 of the argument list for each interpretation of the operation.
21489 (Try_Object_Operation): The designated type of an access parameter may
21490 be an incomplete type obtained through a limited_with clause, in which
21491 case the primitive operations of the type are retrieved from its full
21493 (Analyze_Call): If this is an indirect call, and the return type of the
21494 access_to_subprogram is incomplete, use its full view if available.
21496 2005-09-01 Javier Miranda <miranda@adacore.com>
21497 Gary Dismukes <dismukes@adacore.com>
21499 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
21500 access types the null-exclusion and access-to-constant attributes must
21502 (Analyze_Return_Statement): When the result type is an anonymous access
21503 type, apply a conversion of the return expression to the access type
21504 to ensure that appropriate accessibility checks are performed.
21505 (Analyze_Return_Type): For the case of an anonymous access result type,
21506 generate the Itype and set Is_Local_Anonymous_Access on the type.
21507 Add ??? placeholder for check to disallow returning a limited object
21508 in Ada 2005 unless it's an aggregate or a result of a function call.
21509 Change calls from Subtype_Mark to Result_Definition.
21510 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
21511 Result_Definition in call to Make_Function_Specification.
21512 (Build_Body_To_Inline): Change Set_Subtype_Mark to
21513 Set_Result_Definition.
21514 (Make_Inequality_Operator): Change formal Subtype_Mark to
21515 Result_Definition in call to Make_Function_Specification.
21516 (Process_Formals): Create the new null-excluding itype if required.
21517 (New_Overloaded_Entity): For an entity overriding an interface primitive
21518 check if the entity also covers other abstract subprograms in the same
21519 scope. This is required to handle the general case, that is, overriding
21520 other interface primitives and overriding abstract subprograms inherited
21521 from some abstract ancestor type.
21522 (New_Overloaded_Entity): For an overriding entity that comes from
21523 source, note the operation that it overrides.
21524 (Check_Conformance, Type_Conformant): Addition of one new formal
21525 to skip controlling formals in the analysis. This is used to
21526 handle overloading of abstract interfaces.
21527 (Base_Types_Match): Add missing case for types imported from
21528 limited-with clauses
21529 (New_Overloaded_Entity): Add barrier to protect the use of
21530 the "alias" attribute.
21532 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21534 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
21535 verify that the procedure and the entry are mode conformant.
21536 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
21537 as a different operator, which is often a cut-and-paste error.
21539 2005-09-01 Javier Miranda <miranda@adacore.com>
21540 Ed Schonberg <schonberg@adacore.com>
21542 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
21543 used in controlling parameters exclude null because it is necessary to
21544 read the tag to dispatch, and null has no tag.
21545 (Override_Dispatching_Operation): If the previous operation is inherited
21546 from an interface, it becomes hidden and does not participate in later
21549 2005-09-01 Javier Miranda <miranda@adacore.com>
21550 Ed Schonberg <schonberg@adacore.com>
21551 Gary Dismukes <dismukes@adacore.com>
21553 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
21554 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
21555 the expander will generate the corresponding run-time check to evaluate
21557 (Resolve_Call): Check for legal type of procedure name or prefix that
21558 appears as a trigger in a triggering alternative.
21559 (Valid_Conversion): If expression is ambiguous and the context involves
21560 an extension of System, remove System.Address interpretations.
21561 (Resolve_Qualified_Expression): Reject the case of a specific-type
21562 qualification applied to a class-wide argument. Enhance comment
21563 to explain checking of Original_Node.
21564 (Resolve_Type_Conversion): The location of the error message was not
21565 general enough to handle the general case and hence it has been removed.
21566 In addition, this patch improves the text of the message.
21567 (Resolve_Type_Conversion): Add missing support for access to interface
21569 (Resolve_Type_Conversion): If the target is a class-wide interface type,
21570 do not expand if the expression is the actual in a call, because proper
21571 expansion will take place when the call itself is expanded.
21572 (Resolve_Allocator): If the context is an unchecked conversion, the
21573 allocator inherits its storage pool, if any, from the target type of

21579 * sem_type.adb (Add_One_Interp): If a candidate operation is an
21580 inherited interface operation that has an implementation, use the
21581 implementation to avoid spurious ambiguities.
21582 (Interface_Present_In_Ancestor): In case of concurrent types we can't
21583 use the Corresponding_Record_Typ attribute to look for the interface
21584 because it is set by the expander (and hence it is not always
21585 available). For this reason we traverse the list of interfaces
21586 (available in the parent of the concurrent type).

21599 capture if it is generated in the second operand of a short-circuit
21601 Do not capture values for variables with address clauses.
21602 (Is_Object_Reference): Treat a function call as an object reference only
21603 if its type is not Standard_Void_Type.

22391 longer protected objects. They have been replaced by lower-level
22392 suspension objects made up by a mutex and a condition variable (or
22393 their equivalent given a particular OS) plus some internal data to
22394 reflect the state of the suspension object.

22771 misaligned because of packing or representation clauses.
22772 (Is_Legal_Copy): New predicate to determine whether a possibly
22773 misaligned in-out actual can actually be passed by copy/return. This
22774 is an error in case the type is by_reference, and a warning if this is
22775 the consequence of a DEC import pragma on the subprogram.
22776 (Expand_Call, Freeze_Subprogram): Modified to give support to abstract
22778 (Expand_Inlined_Call): Mark temporary generated for the return value as

22796 (Expand_Subtype_From_Expr): If the expression is a selected component
22797 within an initialization procedure, compute its actual subtype, because
22798 the component may depend on the discriminants of the enclosing record.
22800 * i-cpp.ads, i-cpp.adb:
22801 This package has been left available for compatibility with previous

22826 the generic that is created to represent the formal package.
22827 (Analyze_Package_Instantiation): Instantiate body immediately if the
22828 package is a predefined unit that contains inlined subprograms, and
22829 we are compiling for a Configurable_Run_Time.

22834 error message condition, null procedures are correctly detected now.
22835 (New_Overloaded_Entity): Bypass trivial overriding indicator check

22845 by the corresponding record type.
22846 (Analyze_Subprogram_Body): Undo the previous work.
22847 (Analyze_Procedure_Call): If the call has the form Object.Op, the

22851 subprogram_specification that returns true if some non
22852 class-wide interface subprogram is found

22855 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
22856 access to subprograms must be recursive.
22857 (Is_Unchecked_Conversion): Improve the test that recognizes
22858 instantiations of Unchecked_Conversion, and allows them in bodies that
22859 are to be inlined by the front-end. When the body comes from an
22860 instantiation, a reference to Unchecked_Conversion will be an
22861 Expanded_Name, even though the body has not been analyzed yet.

22880 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
22881 in the case where the target type is an anonymous access type of an
22882 object or component (that is, when Is_Local_Anonymous_Access is true).
22883 Prevent the special checks for conversions of access discriminants in
22884 the case where the discriminant belongs to a nonlimited type, since
22885 such discriminants have their accessibility level defined in the same
22886 way as a normal component of an anonymous access type.
22887 (Resolve_Allocator): When an allocator's designated type is a class-wide
22888 type, check that the accessibility level of type given in the
22889 allocator's expression or subtype indication is not statically deeper
22890 than the level of the allocator's access type.

22906 pragma Restrictions (No_Obsolescent_Features).
22907 (Check_Direct_Boolean_Operator): If the boolean operation has been
22908 constant-folded, there is nothing to check.
22909 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
22910 check on possible violation of restriction No_Direct_Boolean_Operators
22911 until after expansion of operands, to prevent spurious errors when

22947 both bound checks, rather than a conjunction.
22948 (Insert_Valid_Check): If the expression is an actual that is an indexed
22949 component of a bit-packed array, force expansion of the packed element
22950 reference, because it is specifically inhibited elsewhere.

23916 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
23917 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
23918 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
23919 analyzed if expansion is disabled (which could otherwise cause spurious
23920 error messages if expansion has been disabled due to previous
23921 (unrelated) errors).
23923 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
23924 is disabled, the entity denoted by the argument is the access type
23925 itself, not an underlying record type, so there is no need to go back
23926 to the Corresponding_Remote_Type.

23929 Robert Dewar <dewar@adacore.com>
23931 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
23932 expand a call to an instance of
23933 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
23934 Constructor actual of the instance. A class-wide membership
23935 check is also generated, to ensure that the tag passed to the instance
23936 denotes a type in the class.
23937 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
23938 of Name_Generic_Dispatching_Constructor.
23940 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
23941 05 unit for AI-260-02).

23955 the case of renaming of stream attributes when the renaming denotes a
23956 generic formal subprogram association for an abstract formal subprogram.
23957 Check that the attribute is a primitive stream attribute (and not
23958 a class-wide stream attribute) and then rewrite the attribute name
23959 as the name of the appropriate compiler-generated stream primitive.
23961 2005-03-29 Robert Dewar <dewar@adacore.com>
23963 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

23970 * freeze.adb (Freeze_Record_Type): If the type of the component is an
23971 itype whose parent is controlled and not yet frozen, do not create a
23972 freeze node for the itype if expansion is disabled.
23974 2005-03-29 Vincent Celier <celier@adacore.com>
23976 * make.adb (Gnatmake): Don't fail if the main project file is declared
23977 as having no Ada sources. Do not display message "no sources to
23978 compile" in quiet output.
23980 2005-03-29 Doug Rupp <rupp@adacore.com>
23982 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

23993 missing TYPE Improve the error message generated when compiling a
23994 limited interface in Ada83 or Ada95 mode.
23996 2005-03-29 Robert Dewar <dewar@adacore.com>
23998 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
23999 rather than proceed ahead using a junk attribute name.
24001 2005-03-29 Vincent Celier <celier@adacore.com>
24003 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
24005 * prj-part.adb (Parse_Single_Project): Set the location of a project
24006 on its defining identifier, rather than on the reserved word "project".
24008 * prj-proc.adb (Expression): Adapt to the fact that default of external
24009 references may be string expressions, not always literal strings.
24010 (Recursive_Process): Set Display_Name equal to Name
24011 when Location is No_Location, that is when there is no actual file.
24012 Get the Display_Name of the project from the source, when it is not a
24014 (Process): Use the Display_Name in error messages
24016 * prj-strt.adb (External_Reference): Allow default to be string
24017 expressions, not only literal strings.
24019 2005-03-29 Vincent Celier <celier@adacore.com>
24021 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
24022 file and the reference symbol file to be the same file.
24024 2005-03-29 Thomas Quinot <quinot@adacore.com>
24026 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
24027 forbid conversion of a local access-to-subprogram type to a remote one.
24029 * sem_util.adb (Wrong_Type): For a record type that is the expanded
24030 equivalent type for a remote access-to-subprogram type, go back to the
24031 original RAS entity when displaying an error message, so the casing is
24032 the original source casing.
24034 2005-03-29 Robert Dewar <dewar@adacore.com>
24036 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
24039 2005-03-29 Ed Schonberg <schonberg@adacore.com>
24041 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
24042 subtype if code is being pre-analyzed, to prevent un-expanded
24043 references to protected formals, among others.
24044 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
24045 interpretation that can be a call, include the result of the call as a
24046 possible interpretation of the dereference.
24048 * sem_ch5.adb (Process_Bounds): Determine type of range by
24049 pre-analyzing a copy of the original range, and then analyze the range
24050 with the expected type.
24052 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
24053 with an overloaded prefix where not all interpretations yield an
24054 access to subprogram, do not rewrite node as a call.
24055 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
24056 the node as a call once the context identifies the interpretation of
24057 the prefix whose call yields the context type.
24058 (Valid_Conversion): For the case of a conversion between
24059 local access-to-subprogram types, check subtype conformance using
24060 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
24061 detailed error message.
24063 2005-03-29 Ed Schonberg <schonberg@adacore.com>
24065 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
24066 indicator, indicate that the formal can never be null.
24067 (Process_Formals): If a formal has a non_null indicator, insert the
24068 resulting subtype immediately before the enclosing subprogram decl,
24069 and not at the beginning of the corresponding declarative part, to
24070 prevent access before elaboration (Ada2005).

24179 to install the visible declarations of the enclosing scope of a
24180 record_type_with_private to establish the proper visibility before
24181 freezing the entity and related subprograms.

24191 (Check_Stream_Attribute): Move the code for 13.13.2(9/1) enforcement
24192 into a new Check_Attr subprogram, in order to provide a more
24193 explanatory error message (including the name of the missing attribute).
24194 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
24195 subprogram determines whether a default implementation exists for a
24196 given stream attribute.
24197 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
24198 Determine whether to generate a default implementation for each stream

24673 (Task_Body_Procedure): New subprogram to read this attribute.
24674 (Set_Task_Body_Procedure): New subprogram to set this attribute.
24675 (Has_Controlled_Component): Now applies to all entities.
24676 This is only a documentation change, since it always worked to apply
24677 this to other than composite types (yielding false), but now this is
24679 Update documentation on Must_Be_Byte_Aligned for new spec
24681 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
24682 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
24683 uses of the Access_Disp_Table attribute to reference the first dispatch
24684 table associated with a tagged type. As
24685 part of the implementation of abstract interface types,
24686 Access_Disp_Table has been redefined to contain a list of dispatch
24687 tables (rather than a single dispatch table).
24688 Similarly, upgrade all the references to Tag_Component by the
24689 new attribute First_Tag_Component.
24690 (Find_Inherited_TSS): Moved to exp_tss.
24691 Clean up test in Expand_N_Object_Declaration for cases
24692 where we need to do a separate assignment of the initial value.
24693 (Expand_N_Object_Declaration): If the expression in the
24694 declaration of a tagged type is an aggregate, no need to generate an
24695 additional tag assignment.
24696 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
24698 Bit packed array ops are only called if operands are known to be
24700 (Component_Equality): When returning an N_Raise_Program_Error statement,
24701 ensure that its Etype is set to Empty to avoid confusing GIGI (which
24702 expects that only expressions have a bona fide type).
24703 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
24704 determine the amount of data to be copied.
24706 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
24707 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
24708 INTERFACE_TYPE_DEFINITION ::=
24709 [limited | task | protected | synchronized] interface
24710 [AND interface_list]
24712 * par-ch3.adb (P_Type_Declaration): Modified to give support to
24714 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
24716 (P_Interface_Type_Definition): New subprogram that parses the new
24717 syntax rule of Ada 2005 interfaces
24718 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
24719 messages by the correct RENAMES (quotes removed).
24721 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
24722 attribute First_Tag_Component.
24724 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
24725 (Interface_List, Set_Interface_List): New subprograms.
24726 (Interface_Present, Set_Interface_Present): New subprograms.
24727 (Limited_Present, Set_Limited_Present): Available also in derived
24728 type definition nodes.
24729 (Protected_Present, Set_Protected_Present): Available also in
24730 record type definition and
24731 derived type definition nodes.
24732 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
24733 (Task_Present, Set_Task_Present): New subprogram.
24734 (Task_Body_Procedure): Removed.
24735 (Set_Task_Body_Procedure): Removed.
24736 These subprogram have been removed because the attribute
24737 Task_Body_Procedure has been moved to the corresponding task type
24738 or task subtype entity to leave a field free to store the list
24739 of interfaces implemented by a task (for AI-345)
24740 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
24741 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
24742 expression flag Do_Range_Check
24743 (Exception_Junk): Change to Flag7 to accomodate above change
24744 (Box_Present, Default_Name, Specification, Set_Box_Present,
24745 Set_Default_Name, Set_Specification): Expand the expression
24746 "X in N_Formal_Subprogram_Declaration" into the corresponding
24747 two comparisons. Required to use the csinfo tool.
24749 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
24750 "with string" given.
24752 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
24755 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
24758 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
24759 attribute Task_Body_Procedure rather than the old semantic field that
24760 was available in the task_type_declaration node.
24762 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
24763 interface type definitions.
24764 (P_Formal_Derived_Type_Definition): Modified to handle the list of
24767 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
24768 task type declaration.
24769 (P_Protected): Modified to handle the list of interfaces in a
24770 protected type declaration.
24772 2005-03-15 Doug Rupp <rupp@adacore.com>
24773 Vincent Celier <celier@adacore.com>
24775 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
24776 (Gen_Output_File_C): Likewise.
24777 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
24779 2005-03-15 Thomas Quinot <quinot@adacore.com>
24781 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
24782 is an N_Raise_Constraint_Error node, create a new copy of it without
24783 going through a call to Duplicate_Subexpr.
24785 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
24786 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24787 Nicolas Setton <setton@adacore.com>
24788 Ed Schonberg <schonberg@adacore.com>
24794 * decl.c (gnat_to_gnu_field): Reject aliased components with a
24795 representation clause that prescribes a size not equal to the rounded
24796 size of their types.
24797 (gnat_to_gnu_entity, case E_Component): Always look at
24798 Original_Record_Component if Present and not the entity.
24799 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
24800 of tagged extension types by not making field for components that are
24802 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
24803 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
24804 expression to the type of the object when the object is constant.
24805 Reverse defer_debug_incomplete_list before traversing it, so that trees
24806 are processed in the order at which they were added to the list. This
24807 order is important when using the stabs debug format.
24808 If we are deferring the output of debug information, also defer this
24809 output for a function return type.
24810 When adding fields to a record, prevent emitting debug information
24811 for incomplete records, emit the information only when the record is
24813 (components_to_record): New parameter defer_debug.
24814 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
24815 (gnat_to_gnu_field_decl): New function.
24816 (substitution_list, annotate_rep): Call it.
24817 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
24818 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
24819 No longer update discriminants to not be a COMPONENT_REF.
24820 (copy_alias_set): Strip padding from input type; also handle
24821 unconstrained arrays properly.
24823 * gigi.h (write_record_type_debug_info): New function.
24824 Convert to use ANSI-style prototypes. Remove unused
24825 declarations for emit_stack_check, elab_all_gnat and
24826 set_second_error_entity.
24827 (gnat_to_gnu_field_decl): New decl.
24829 * utils.c (write_record_type_debug_info): New function.
24830 (finish_record_type): Delegate generation of debug information to
24831 write_record_type_debug_info.
24832 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
24833 (update_pointer_to): Fix pasto.
24834 (convert) <UNION_TYPE>: Accept slight type variations when
24835 converting to an unchecked union type.
24837 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
24838 replace the N_Freeze_Entity with a null statement.
24840 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
24841 within a constrained subcomponent of an enclosing record, place the
24842 freeze nodes in the scope stack entry for the enclosing record.
24843 (Undelay_Type): New Subprogram.
24844 (Set_Small_Size): Pass T, the type to modify; all callers changed.
24845 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
24846 within records; allow them to have freeze nodes if their base types
24849 * exp_util.adb (Remove_Side_Effects): Properly test for
24850 Expansion_Delayed and handle case when it's inside an
24851 N_Qualified_Expression.
24853 * sem_ch3.adb (Derived_Type_Declaration): New predicate
24854 Comes_From_Generic, to recognize accurately that the parent type in a
24855 derived type declaration can be traced back to a formal type, because
24856 it is one or is derived from one, or because its completion is derived
24858 (Constrain_Component_Type): If component comes from source and has no
24859 explicit constraint, no need to constrain in in a subtype of the
24861 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
24862 Minor change to propagate Is_Ada_2005 flag
24864 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
24865 Expansion_Delayed is False.
24866 (assoc_to_constructor): Ignore fields that have a
24867 Corresponding_Discriminant.
24868 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
24869 function returns "by target", dereference the target pointer using the
24870 type of the actual return value.
24871 <all>: Be prepared for a null gnu_result.
24872 (processed_inline_subprograms): Check flag_really_no_inline
24873 instead of flag_no_inline.
24874 (set_second_error_entity): Remove unused function.

24879 2005-03-15 Robert Dewar <dewar@adacore.com>
24880 Ed Schonberg <schonberg@adacore.com>
24881 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24883 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
24884 Must_Be_Byte_Aligned for cases where we do not need to use a
24885 System.Pack_nn unit.
24887 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
24889 Needed now that we do some processing for IN parameters as well. This
24890 may well fix some unrelated errors.
24891 (Expand_Call): Handle case of unaligned objects (in particular those
24892 that come from packed arrays).
24893 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
24894 renamed entity is an inherited operation, re-expand the call using the
24895 original operation, which is the one to call.
24896 Detect attempt to inline parameterless recursive subprogram.
24897 (Represented_As_Scalar): Fix to work properly with private types
24898 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
24899 accurate estimate. Yields True in far fewer cases than before,
24900 improving the quality of code that depends on this test.
24902 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
24903 over both visible and private declarations to remove them from tree,
24904 and mark subprograms declared in package as eliminated, to prevent
24905 spurious use in subsequent compilation of generic units in the context.
24907 * exp_util.ads: Minor cleanup in variable names
24909 * sem_eval.ads, sem_eval.adb: Minor reformatting
24910 (Compile_Time_Known_Bounds): New function
24912 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24914 * exp_ch7.adb (Convert_View): Use base types of underlying types when
24915 determining whether an unchecked conversion is needed for the argument
24916 of an initialization call.
24918 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24920 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
24921 that appears in the instantiation rather than the internal subtype
24922 generated in the wrapper package, to avoid anomalies in gigi when the
24923 target is derived from a private type whose full view is an access type.
24925 2005-03-15 Robert Dewar <dewar@adacore.com>
24927 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
24929 Add documentation to replace the use of this flag
24930 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
24933 2005-03-15 Thomas Quinot <quinot@adacore.com>
24935 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
24936 here from exp_attr so it can be shared between exp_attr and exp_dist.
24937 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
24938 all TSS names, not a subset thereof, and the previous name introduced
24939 an unnecessarily confusion that a distinction might exist between
24940 "OK" TSS names and some "not OK" TSS names.
24942 2005-03-15 Doug Rupp <rupp@adacore.com>
24944 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
24947 2005-03-15 Pascal Obry <obry@adacore.com>
24948 Eric Botcazou <ebotcazou@adacore.com>
24952 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
24953 when IN_RTS. This is to work around a bootstrap path problem.
24955 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
24956 table and pass it to __gnat_install_SEH_handler().
24957 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
24959 * lang.opt: Fix specification of -fRTS=.
24961 2005-03-15 Doug Rupp <rupp@adacore.com>
24962 Bernard Banner <banner@adacore.com>
24963 Vincent Celier <celier@adacore.com>
24964 Arnaud Charlet <charlet@adacore.com>
24967 This change works fine when gnatlib is built from the gcc directory,
24968 but does not work when using the libada Makefile, since GCC_FOR_TARGET
24969 is not passed to ada/Makefile.in, so more work is needed by a
24970 Makefile/configure expert.
24972 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
24973 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
24974 Setup gnatlink switch -M for x86_64 linux, as it is already setup
24976 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
24977 Run ranlib on libgccprefix.a
24978 Define PREFIX_OBJS for Darwin, to build libgccprefix.
24979 (ADA_INCLUDE_SRCS): Split Ada packages.
24981 2005-03-15 Robert Dewar <dewar@adacore.com>
24983 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
24985 * impunit.adb: Add GNAT.UTF_32
24987 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
24989 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
24990 now uses GNAT.UTF_32).
24992 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
24993 capabilities for categorizing characters using Unicode categories
24995 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24997 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
24998 instantiation that has been rewritten as a package body, retrieve spec
24999 to generate proper name for implicit_with_clause.
25000 (Install_Parents): Recognize a parent that is an instantiation but has
25001 been rewritten as a package declaration during analysis.
25003 2005-03-15 Javier Miranda <miranda@adacore.com>
25004 Ed Schonberg <schonberg@adacore.com>
25006 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
25007 parameter reported some error we immediately return. This improves the
25008 behaviour of the frontend in case of errors.
25009 (Install_Parent, Remove_Parent): Introduce new flag
25010 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
25011 ancestor of a generic child unit, when the child is being instantiated.
25012 (Inline_Instance_Body): If we are compiling the private
25013 part or the body of a child unit, restore the proper visibility of the
25014 parents after compiling the instance body.
25016 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25017 Javier Miranda <miranda@adacore.com>
25020 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
25021 of a private type, in which case it is underlying_type that denotes
25022 the proper task. Also modified to use the new entity attribute
25023 that is directly available in the task type and task subtype entities
25024 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
25025 arrays when other dimensions than the first are constrained by
25026 discriminants of an enclosing record.
25027 (Insert_Explicit_Dereference): If the prefix is an indexed component or
25028 a combination of indexed and selected components, find ultimate entity
25029 and generate the appropriate reference for it, to suppress spurious
25031 (Note_Possible_Modification): If an entity name has no entity, return.
25032 (Is_Variable): A function call never denotes a variable.
25033 (Requires_Transient_Scope): For record types, recurse only on
25034 components, not on internal subtypes that may have been generated for
25035 constrained components.
25037 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25039 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
25040 Eliminated as candidates for resolution. Both efficient, and avoids
25041 anomalies with operators declared in deleted code.
25042 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
25043 expansion is disabled (as when compiling a generic) to prevent spurious
25044 warnings on prefixes of selected components.
25046 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25048 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
25049 attached to a list before checking whether it appears in the private
25050 declarations of the current package.
25051 (Make_Inequality_Operator): Insert declaration in proper declarative
25052 list rather than just setting the Parent field, so that
25053 Is_Private_Declaration can handle it properly.
25055 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25057 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
25058 a renaming a body, check that the renamed subprogram in not intrinsic.
25059 (Find_Direct_Name): If several use_visible entities hide
25060 each other, and the context is a predefined file compiled through
25061 rtsfind, keep only the entity that comes from a predefined file.
25063 2005-03-15 Geert Bosch <bosch@adacore.com>
25065 * s-fatgen.adb (Valid): Extend special exceptions to account for long
25066 long float padding to also cover AMD64 and IA64.
25068 2005-03-15 Gary Dismukes <dismukes@adacore.com>
25070 * s-imgwch.adb: Add with and use of Interfaces.
25071 (Img_Wide_Character): Change type of Val to Unsigned_16.
25072 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
25074 2005-03-15 Matthew Gingell <gingell@adacore.com>
25076 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
25078 2005-03-15 Robert Dewar <dewar@adacore.com>
25080 * usage.adb: Add missing lines for -gnat95 and -gnat05 switches
25082 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
25084 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
25086 2005-03-15 Robert Dewar <dewar@adacore.com>
25088 * s-bitops.adb, s-bitops.ads,

25099 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
25101 * utils2.c (build_binary_op): Fix typo.
25103 2005-03-15 Doug Rupp <rupp@adacore.com>
25105 * s-crtl.ads (popen,pclose): New imports.

25109 * comperr.adb (Compiler_Abort): remove references to obsolete
25110 procedures in the bug boxes for various GNAT builds.
25112 2005-03-15 Vincent Celier <celier@adacore.com>
25114 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

25117 Arnaud Charlet <charlet@adacore.com>
25118 Robert Dewar <dewar@adacore.com>
25119 Cyrille Comar <comar@adacore.com>
25120 Sergey Rybin <rybin@adacore.com>
25122 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
25123 too specific and long-winded to be appropriate for the GNAT User's
25125 Warn about use of GCC switches not documented in the GNAT User's Guide,
25126 as these may cause generated code to not conform to Ada semantics.
25127 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
25128 Add documentation for -gnat95 and -gnat05 switches
25129 Remove paragraph documenting obsolete way to refer to third party
25131 Add a few references to Ada_05 that were missing.
25132 Update documentation on -gnatZ/-gnatL.
25133 Document limitation when using -m64 under Solaris.
25134 Change the "Name Casing" subsection of the pretty-printer section
25135 according to the changes in the dictionary processing.
25137 * gnat_rm.texi: Document the Ada_05 pragma.
25138 Section on record representation clauses describes the new more

25548 the formal subprogram.
25549 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
25550 which is an unclean use of that field, we set the new field

25564 subprogram only if inner one comes from source.
25565 (Analyze_Function_Call): If the call is given in object notation, the

25567 argument list. After analyzing the name, if the call has been rewritten
25568 and the result type is set, no further analysis is needed.
25569 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
25570 mark in function specification, in a context where the formals are
25571 visible and hide outer homographs.
25573 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
25574 as the tagged type for the cases of abstract formal subprograms and
25575 renamings of those. Clean up spec comments.
25576 (Check_Dispatching_Context): Add error message to indicate "abstract
25577 procedure", covering the case of a call to a formal abstract procedure
25578 that has statically tagged operands.
25579 (Check_Dispatching_Call): Check for the case of an actual given by
25580 a tag-indeterminate function call whose type is an ancestor of the
25581 containing call's associated tagged type. This situation can occur
25582 for inherited primitives with function defaults. In this case we
25583 use the tagged type's tag directly as the controlling argument for

25650 GNAT.OS_Lib.Set_Close_On_Exec.
25652 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
25653 the parent side as close-on-exec so that they are not inherited by the

25660 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
25664 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
25665 on the field if Pragma Component_Alignment (Storage_Unit).
25666 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
25667 side-effects as if it were a constant; also make SAVE_EXPR to protect
25669 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
25671 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.

25685 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25687 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
25688 component of an array of arrays in an assignment context, and the
25689 aggregate has component associations that require sliding on
25690 assignment, force reanalysis of the aggregate to generate a temporary
25691 before the assignment.
25692 (Must_Slide): Make global to the package, for use in Gen_Assign.
25694 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25696 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
25697 unchecked union with no inferable discriminants, return a
25698 Raise_Program_Error node, rather than inserting it at the point the
25700 (Expand_Record_Equality, Component_Equality): Handle properly the case
25701 where some subcomponent is an unchecked union whose generated equality
25702 code raises program error.

25710 Arnaud Charlet <charlet@adacore.com>
25712 * init.c (__gnat_initialize): Add a new parameter eh which contains the
25713 address of the exception registration. The Win32 version of this
25714 routine calls __gnat_install_SEH_handler() to initialize the SEH
25715 (Structured Exception Handling) handler.
25716 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
25717 SEH (Structured Exception Handling) now.
25718 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
25719 (__gnat_initialize for ppc-vxworks): Adjust comments and the
25720 preprocessor condition protecting the call to the extra eh setup
25721 subprogram, which is only available for the ppc target.
25722 (__gnat_clear_exception_count): replaced reference to
25723 variable taskIdCurrent by call to taskIdSelf(), cleaner.
25725 * seh_init.c: New file.

25728 (GNATBIND_OBJS): Idem.
25730 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
25731 routine takes a new parameter (a pointer to the exception registration
25732 for the SEH (Structured Exception Handling) support.
25734 * raise.h: (__gnat_install_SEH_handler): New prototype.
25735 Update copyright notice.
25737 * s-tassta.adb (Task_Wrapper): Declare the exception registration
25738 record and initialize it by calling __gnat_install_SEH_handler.

25763 -shared-libgcc is now used by default on some systems (e.g. linux with
25765 Remove references to Makefile.prolog/generic, no longer used.
25767 2005-02-09 Vincent Celier <celier@adacore.com>
25769 * prj-makr.adb (Process_Directory): Put file name in canonical case
25770 before matching against the patterns.
25771 If gnatname has been invoked as <prefix>-gnatname
25772 then invoke the compiler as <prefix>-gcc, not just "gcc".
25774 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25776 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
25777 with expansion disabled. The actual subtype is needed among other
25778 places when the selected component appears in the context of a loop
25779 bound, and denotes a packed array.
25780 (Operator_Check): Always use the first subtype in the
25781 error message, to avoid the appearance of internal base types.
25782 (Transform_Object_Operation): Copy each actual in full
25783 to the parameter associations of the constructed call, rather than
25784 using the shallow copy mechanism of New_Copy_List. This ensures that
25785 the chaining of named associations is done properly.
25786 (Complete_Object_Operation): Rewrite node, rather than
25787 replacing it, so that we can trace back to the original selected
25790 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
25791 and calls that use object notation, if the called function is not
25792 declared in a withed unit, place the elaboration constraint on the
25793 unit in the context that makes the function accessible.
25794 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
25795 imposes an elaboration constraint between two packages.
25797 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25799 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
25800 views of a private type after handling its private dependents, to
25801 maintain proper stack discipline between entry and exit from the

25827 we now use by default.
25829 * xsnames.adb: Adjust end of file test to look for five space followed
25830 by '#' instead of six spaces. The format of xsnames.adb was modified
25831 in the last update.
25833 * a-numeri.ads: Add reference to AI-388 for greek letter pi
25836 * clean.adb: Minor reformatting.
25838 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,

25844 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
25847 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
25849 2005-02-09 Sergey Rybin <rybin@adacore.com>
25851 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
25852 the difference between compact and incompact layout and add the record
25853 representation clause to the example illustrating different layouts.
25854 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
25855 component clauses").

25859 * gnat_ugn.texi: Fix typos.
25860 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

25909 2005-02-09 Arnaud Charlet <charlet@adacore.com>
25911 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
25912 since this procedure is now too complex to be worth inlining.

26101 exception Bad_R_Line, instead of calling Fatal_Error, so that, when
26102 Ignore_Errors is True, default restrictions are set and scanning of the

26162 is to check if two function signatures for a call-site and a callee are
26163 compatible enough for the call to be valid. The underlying purpose is
26164 to check if a call to a mapped builtin is using the right interface.
26165 The current code actually does not check antyhing - this a placeholder
26166 for future refinements.
26167 (gnat_to_gnu_entity) <E_Subprogram_Call>: Add preliminary bits to handle
26168 builtin calls for convention Intrinsic.

26211 variable Dynamic_Async.
26212 (Build_Subprogram_Receiving_Stubs): Make PCS-specific

26217 structure of GARLIC and PolyORB RPC receivers.
26218 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
26220 Simplify elaboration code for RCI packages.
26222 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver

26332 note that it applies to obsolete GNAT features, which was previously
26333 omitted. Second we contrast the behavior with that of the new
26334 Ada 2005 AI-368 restriction No_Obsolescent_Features.
26335 Preliminary rewriting of GNAT & libraries chapter in order to take
26336 into account default project locations & new project manager

26562 (process_attributes): Clear DECL_COMMON again when a section attribute

26580 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
26581 with an implicit dereference as its prefix, use
26582 Insert_Explicit_Dereference instead of merely rewriting the prefix into

26584 prefix is generated, if appropriate.
26586 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
26587 dereference is rewritten to an explicit one, generate a reference to
26588 the entity denoted by its prefix using the original prefix node, so
26589 the dereference can be properly recorded as a read of the denoted
26590 access value, if appropriate.
26592 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
26593 emitting 'assigned but never read' warning on a variable on the basis

26706 prefix when operating under -gnatc. Necessary to avoid spurious
26707 'variable assigned but never read' warnings in that mode.
26708 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
26709 is a non-overloaded implicit dereference, call the above subprogram to
26710 ensure proper recording of references.
26712 2004-12-07 Gary Dismukes <dismukes@adacore.com>
26714 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

26764 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
26765 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
26766 and -eit to -ept. Added qualifier

26775 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
26776 internal implementation unit GNAT.Sockets.Thin,
26777 as their usage for sockets is non-portable (using the read and write
26778 functions from the system runtime library is fine on UNIX but won't
26779 work under Windows).

26832 (Setup_Exception): Do nothing in the GNAT SJLJ case.
26834 * gigi.h (others_decl, all_others_decl): New decls representing the
26835 new Others_Value and All_Others_Value objects.
26836 (struct attrib): Rename "arg" component as "args", since GCC expects a
26837 list of arguments in there.
26839 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
26840 corresponding objects exported by a-exexpr, instead of hardcoded dummy
26843 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
26844 others_decl and all_others_decl instead of hardcoded dummy addresses
26845 to represent "others" and "all others" choices, which is cleaner and
26846 more flexible with respect to the possible eh pointer encoding policies.
26848 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
26849 (process_attributes): Account for the naming change of the "args"
26850 attribute list entry component.

26853 cumulating attributes for different entities into a single list.
26854 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
26855 attributes for the current entity and propagate first subtype
26856 attributes to other subtypes.
26857 <E_Procedure>: Attribute arguments are attr->args and not
26858 attr->arg any more.
26859 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
26860 argument provided, as this is what GCC expects. Use NULL_TREE instead

26898 (First_RCI_Subprogram_Id): Document this constant.
26899 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
26901 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
26902 replaced with calls to Get_Library_Unit_Name_String. Previously there
26903 were several instances of the same code in different locations in the
26904 compiler; this checkin completes the replacement of all of these
26905 instances with calls to a common subprogram.
26906 Minor reformatting.
26908 * sem_dist.adb: Remove comment noting that RPC receiver generation
26909 should be disabled for RACWs that implement RASs.

26935 (Expand_Pragma_Psect_Object): New procedure
26936 These procedures contain the revised and cleaned up processing for
26937 these two pragmas. This processing was formerly in Sem_Prag, but
26938 is more appropriately moved here. The cleanup involves making sure
26939 that the pragmas are properly attached to the tree, and that no
26940 nodes are improperly shared.
26942 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
26943 pragmas to Exp_Prag, which is more appropriate.
26944 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to

26951 Use new Make_String_Literal function with string.
26952 (Get_Stream_Convert_Pragma): New function, replaces the use of
26953 Get_Rep_Pragma, which had to be kludged to work in this case.
26955 * freeze.adb: Use new Has_Rep_Pragma function
26957 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
26958 function with string.

26985 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
26986 discriminant of a constrained subtype, analyze the copy of the
26987 corresponding constraint, because in some cases it may be only
26988 partially analyzed.

26991 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
26992 handled controlled or secondary-stack expressions within the
26993 iteration_scheme of a loop.
26995 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
26996 bounds that may contain functions calls, to prevent memory leaks when
26997 the bound contains a call to a function that uses the secondary stack.
26998 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
26999 generate temporaries for loop bounds that might contain function calls
27000 that require secondary stack and/or finalization actions.

27003 selected component and the selector is overloadable (not just a
27004 function) treat as function call, Analyze_Call will disambiguate if

27007 selected component if expansion is disabled. The actual subtype is only
27008 needed for constraint checks.

27010 not permit objects to be declared of a stream type, or of a
27011 composite type containing a stream.

27014 No_Streams no longer prohibits with'ing this package.
27016 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
27017 discriminants, but the parent base has unknown discriminants, there is
27018 no discriminant constraint to inherit. Such a discrepancy can arise
27019 when the actual for a formal type with unknown discriminants is a
27020 similar private type whose full view has discriminants.
27021 (Analyze_Object_Declaration): If restriction No_Streams is set, then
27022 do not permit objects to be declared of a stream type, or of a
27023 composite type containing a stream.

27028 protected operations.
27030 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
27031 generated name, it complicates decoding in gdb and hinders debugging

27077 procedure Protected_Single_Entry_Call.
27078 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
27079 Detect_Blocking which is redundant with the check done within the

27121 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
27124 * Makefile.in (darwin): Set soext to .dylib.
27126 2004-10-26 Vincent Celier <celier@gnat.com>
27127 Thomas Quinot <quinot@act-europe.fr>
27129 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
27130 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
27131 there is no use of GNAT.Sockets.Constants.
27132 Remove remaining pragma Import for C_Write
27133 Remove C_Read and C_Write from internal implementation unit
27134 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
27135 the read and write functions from the system runtime library is fine
27136 on UNIX but won't work under Windows).
27138 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
27139 (Check_Selector): Use C_Recv instead of C_Read.
27140 Selectors are the GNAT.Sockets abstraction to perform a select()
27141 call on a set of descriptors. To allow abortion of an ongoing
27142 select operation, some data is written to a dedicated socket that
27143 is always monitored.
27144 Under Windows, the write and read library functions cannot operate
27145 on sockets, so we need to use send and recv instead, which is portable
27146 across all supported platforms.
27148 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
27149 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
27150 (using the read and write functions from the system runtime library is
27151 fine on UNIX but won't work under Windows).
27153 2004-10-26 Nicolas Setton <setton@act-europe.fr>
27155 * mlib-tgt-darwin.adb: New file.
27157 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
27158 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
27159 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
27160 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
27163 * Makefile.in: Add support for building shared libraries under Darwin.
27164 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
27165 the low level EH init subprogram to be called from __gnat_initialize.
27167 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
27168 indicates which options to pass to the archive indexer.
27170 * mlib-utl.adb: Add support for calling ranlib with additional
27171 options. This is needed for instance under Mac OS X.
27172 (Ranlib_Options): New global variable, used to store the potential
27173 options to pass to ranlib.
27174 (Ar): Use Ranlib_Options when spawning ranlib.
27175 (Initialize): Set the value of ranlib option.
27177 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
27179 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
27180 instead of 8K, to reflect the real potential needs for stack-checking
27183 2004-10-26 Pascal Obry <obry@gnat.com>
27185 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
27187 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
27188 Windows only the initial thread stack size can be set so it is good to
27189 start we a low stack size.
27190 The OS will adjust the size as needed.
27192 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
27193 Nicolas Setton <setton@act-europe.fr>
27195 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
27196 "__unix__" instead of "unix".
27197 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
27198 sections were just mistakenly ignored. The former is
27199 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
27200 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
27201 of hpux. This prevents an unwanted definition of the symbol
27202 convert_addresses in adaint.o.
27204 2004-10-26 Gary Dismukes <dismukes@gnat.com>
27206 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
27207 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
27209 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27211 * a-filico.ads, a-filico.adb: fix incorrect header.
27213 2004-10-26 Javier Miranda <miranda@gnat.com>
27215 * a-ststio.ads: Fix typo in identifier
27217 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27219 * sem_ch4.adb: Minor reformatting.
27221 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27223 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
27224 enabled, check the result of unary and binary operations when the
27225 expression is the right-hand side of an assignment.
27227 2004-10-26 Vincent Celier <celier@gnat.com>
27229 * clean.adb (Delete): Do not output warnings when in quiet output and
27230 not in verbose mode.
27231 (Force_Deletions): New Boolean flag, defaulted to False
27232 (Delete): Only delete a file if it is writable, and when
27233 Force_Deletions is True.
27234 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
27235 (Usage): Line for new switch -f
27236 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
27239 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
27241 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
27242 JM type only if its size matches that of the wrapper. When a size is
27243 prescribed and the field is not aliased, remove the wrapper of a JM
27244 type only if the size is not greater than that of the packed array.
27245 (gnat_to_gnu_entity): Change the extension of packed array wrappers
27248 2004-10-26 Geert Bosch <bosch@gnat.com>
27250 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
27251 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
27252 (Pred): Implement in terms of Succ.
27254 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27256 * exp_aggr.adb (Safe_Component): An aggregate component that is an
27257 unchecked conversion is safe for in-place use if the expression of the
27258 conversion is safe.
27259 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
27260 be expandable in place even if the aggregate does not come from source.
27261 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
27262 designated object of an allocator in place, rather than building it
27263 first on the stack. The previous scheme forces a full copy of the array,
27264 and may be altogether unsusable if the size of the array is too large
27265 for stack allocation.
27267 2004-10-26 Robert Dewar <dewar@gnat.com>
27269 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
27270 compares if the component is atomic.
27272 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
27273 array assignment if the component type is atomic.
27275 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27276 Eric Botcazou <ebotcazou@act-europe.fr>
27278 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
27279 is aliased and is a by_reference type, do not pass by copy.
27280 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
27281 detect whether the call is in the right side of an assignment or
27282 the expression of an object declaration. Recurse on component
27283 association within aggregates.
27284 Call it in the condition that determines whether the temporary is
27285 necessary for correct stack-checking.
27287 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27289 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
27290 RACW_Type, used in the PolyORB version.
27291 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
27292 version and the GARLIC version.
27294 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
27295 Rename RCI_Info to RCI_Locator for better consistency between the
27296 GARLIC and PolyORB versions of the distributed systems annex.
27297 (DSA_Implementation_Name): This enumeration lists the possible
27298 implementations of the Partition Communication Subsystem for the
27299 Distributed Systems Annex (DSA). The three available implementations
27300 are the dummy stub implementation (No_DSA), and two versions based on
27301 two different distribution runtime libraries: GARLIC and PolyORB. Both
27302 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
27304 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
27307 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
27308 between the GARLIC and PolyORB versions of the distributed systems
27310 Remove RE_Unbounded_Reclaim_Pool since it is unused.
27312 2004-10-26 Gary Dismukes <dismukes@gnat.com>
27314 * gnat1drv.adb: Suppress calling the back end when
27315 Frontend_Layout_On_Target is true.
27317 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27319 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
27320 Set_Read_Only): New subprograms.
27321 These new routines allow the user to set or unset the Owner execute
27322 and Owner write permission flags on a file.
27324 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
27325 GNAT.OS_Lib.Set_Executable instead of rolling our own.
27327 2004-10-26 Matthew Gingell <gingell@gnat.com>
27329 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
27331 2004-10-26 Pascal Obry <obry@gnat.com>
27333 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
27334 memory before the faulting page we properly test the process read
27335 access for this address using appropriate Win32 routine.
27336 (HPUX sections): guard with "__hpux__" instead of "hpux".
27338 2004-10-26 Robert Dewar <dewar@gnat.com>
27340 * lib-xref.adb (Generate_Reference): Don't complain about reference to
27341 entry parameter if pragma Unreferenced set, since we do not properly
27342 handle the case of multiple parameters.
27344 2004-10-26 Vincent Celier <celier@gnat.com>
27346 * prj-env.adb: (Contains_ALI_Files): New Boolean function
27347 (Ada_Objects_Path.Add): For a library project, add to the object path
27348 the library directory only if there is no object directory or if the
27349 library directory contains ALI files.
27350 (Set_Ada_Paths.Add.Recursive_Add): Ditto
27352 2004-10-26 Vincent Celier <celier@gnat.com>
27354 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
27355 extension of library projects.
27357 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
27358 path defaults to ".:<prefix>/lib/gnat".
27359 (Parse): For an extending all project, allow direct import of a project
27360 that is virtually extended.
27362 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
27363 the specified name is directly imported, return its ID. Otherwise, if
27364 an extension of this project is imported, return the ID of the
27367 2004-10-26 Robert Dewar <dewar@gnat.com>
27369 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
27370 (Sub3): New procedure, used by Scaled_Divide
27371 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
27372 correct more than one instance of failure to propagate carries
27374 (Double_Divide): Handle overflow case of largest negative number
27375 divided by minus one.
27377 * s-arit64.ads (Double_Divide): Document that overflow can occur in
27378 the case of a quotient value out of range.
27381 2004-10-26 Robert Dewar <dewar@gnat.com>
27383 * s-bitops.adb (Bit_Eq): Remove redundant check.
27385 * s-bitops.ads: Minor comment updates
27386 Change some occurrences of Address to System.Address
27388 * s-carsi8.ads: Fix minor cut-and-paste error in comments
27390 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27392 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
27393 accessibility check to prefix that is a protected operation.
27395 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27397 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
27398 empty, post message on stub.
27400 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27401 Javier Miranda <miranda@gnat.com>
27403 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
27404 current instance appears within a unit that is directly in the context
27406 Used to determine whether the body of the instance should be analyzed
27407 immediately after its spec, to make its subprogram bodies available
27408 for front-end inlining.
27409 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
27410 constraint is not allowed on the component type (AARM 12.5.3(3))
27412 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27414 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
27415 'Storage_Pool): enhance, document & limit detection of non-sharable
27418 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
27420 * s-pooglo.ads: Add more documentation now that this pool is properly
27423 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27425 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
27426 or protected type with discriminants, do not constrain the
27427 corresponding record type if the subtype declaration has no
27428 discriminant constraints. This can be the case in source code, or in
27429 the subtype declaration created to rename an actual type within an
27432 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27434 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
27435 different kind of stub (possibly wrong name for file), do not check
27437 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
27438 includes call to some function that returns an unconstrained type, do
27441 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27443 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
27444 appear in the code for the main unit. Dependencies among units in the
27445 context of the main unit are established when those other units are
27446 compiled. Otherwise spurious elaboration constraints can generate
27447 incorrect elaboration circularities.
27449 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27450 Ed Schonberg <schonberg@gnat.com>
27452 * sem_util.adb (Is_Aliased_View): Defend against the case where this
27453 subprogram is called with a parameter that is not an object name. This
27454 situation arises for some cases of illegal code, which is diagnosed
27455 later, and in this case it is wrong to call Is_Aliased, as that might
27456 cause a compiler crash.
27457 (Explain_Limited_Type): Refine previous fix to include
27458 inherited components of derived types, to provide complete information.
27460 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
27461 is the prival for a protected object.
27462 It is necessary to mark this entity as a variable, in addition to
27463 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
27464 modified to avoid checking the Aliased flag on entities that are not
27465 objects. (Checking that flag for non-objects is erroneous and could
27466 lead to a compiler crash).
27468 2004-10-26 Robert Dewar <dewar@gnat.com>
27470 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
27471 X_Frac = 0.5, then we know that the number X must be positive.
27472 (Succ): Remove the same redundant test, and also fix the primary test
27473 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
27475 (Decompose): Add fuller comments to spec
27477 2004-10-26 Pascal Obry <obry@gnat.com>
27479 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
27480 validity (process must have read access). Set to 0 in all other cases.
27481 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
27482 violation on Win32.
27483 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
27484 segmentation violation.
27486 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
27488 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
27489 whose type is a constructed subtype of an aliased object with an
27490 unconstrained nominal subtype, convert the actual to the constructed
27491 subtype before taking its address.
27493 2004-10-26 Vincent Celier <celier@gnat.com>
27495 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
27496 (Is_Path_Name_Case_Sensitive): New function
27498 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
27499 (Base_Name, Simple_Name, Current_Directory, Compose,
27500 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
27503 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27504 Vasiliy Fofanov <fofanov@act-europe.fr>
27505 Vincent Celier <celier@gnat.com>
27507 * gnat_ugn.texi: Generalize "finding memory problems" section into a
27508 "memory management issues" section and document some of the useful
27509 memory pools provided as part of the GNAT library.
27510 Remove "virtual" from declaration of A::method2 in
27511 the simple example of Ada/C++ mixed system.
27512 Library Projects may be virtually extended: their virtual extensions
27513 are not Library Projects.
27514 Added section on extending project hierarchies.
27516 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
27518 * adaint.c (__gnat_get_libraries_from_registry): Cast value
27520 (__gnat_portable_spawn): Remove const.
27522 * mingw32.h (MAXPATHLEN): Check for previous definition.
27524 2004-10-17 Matthias Klose <doko@debian.org>
27526 * gnatvsn.ads: Set gnat library version to 4.0.
27528 2004-10-05 Vincent Celier <celier@gnat.com>
27530 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
27532 2004-10-04 Laurent Guerby <laurent@guerby.net>
27535 * Makefile.in: Define and use RANLIB_FLAGS.
27537 2004-10-04 Pascal Obry <obry@gnat.com>
27539 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
27540 other x86 platforms).
27542 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
27544 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
27545 in general and triggers stack alignment adjustment for thread entry
27546 points on targets where this is necessary.
27548 2004-10-04 Bernard Banner <banner@gnat.com>
27551 * Makefile.in: Add section for powerpc linux
27552 Add variant i-vxwork-x86.ads
27554 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
27556 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
27558 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
27559 table registration calls when need be. Ensures no reference to the crt
27560 ctors symbol are issued in the SJLJ case, which avoids possible
27561 undefined symbol errors in the case of modules to be statically linked
27564 2004-10-04 Javier Miranda <miranda@gnat.com>
27566 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
27567 in-line the code corresponding to subprogram Analyze_Actuals. In
27568 addition, analyze the actuals only in case of subprogram call.
27570 2004-10-04 Ed Falis <falis@gnat.com>
27572 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
27574 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
27576 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
27577 in the documentation.
27579 2004-10-04 Robert Dewar <dewar@gnat.com>
27581 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
27583 (Analyze_Block_Statement): Add circuitry to detect following dead code
27584 (Check_Unreachable_Code): Handle case of block exit
27586 2004-10-04 Robert Dewar <dewar@gnat.com>
27588 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
27589 (XMatchD): Avoid warning for Logic_Error call
27591 2004-10-04 Robert Dewar <dewar@gnat.com>
27593 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
27594 consider expressions buried within a procedure actual to be an actual.
27595 This caused some blowups with uses of packed slices within a procedure
27598 2004-10-04 Robert Dewar <dewar@gnat.com>
27600 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
27601 longer need to be initialized to zero.
27602 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
27603 initialized to zero.
27605 * checks.adb (Expr_Known_Valid): Packed arrays are now always
27606 considered valid, even if the representation is modular. That's correct
27607 now that we no longer initialize packed modular arrays to zero.
27609 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
27610 suffixes. These are now documented as the only cases in which the
27611 debugger ignores outer records.
27612 Previously, the spec allowed arbitrary suffixes for this purpose.
27613 Change name of LJM to JM for packed array pad records
27614 Create separate section on packed array handling, and add a whole new
27615 set of comments to this section describing the situation with packed
27616 modular types and justification requirements depending on endianness.
27618 2004-10-04 Robert Dewar <dewar@gnat.com>

27631 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27633 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
27634 Inline_Always when in Configurable_Run_Time mode.
27636 * sem_prag.adb (Process_Convention): If entity is an inherited
27637 subprogram, apply convention to parent subprogram if in same scope.
27638 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
27639 when in Configurable_Run_Time mode.
27641 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27643 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
27644 class_wide type after component list has been inherited.

27648 * sem_ch12.adb (Check_Generic_Actuals): New predicate
27649 Denotes_Previous_Actual, to handle properly the case of a private
27650 actual that is also the component type of a subsequent array actual.
27651 The visibility status of the first actual is not affected when the
27652 second is installed.
27653 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
27654 make fully recursive the treatment of formals of packages declared
27656 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
27657 the above on exit from an instantiation.
27658 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
27659 current instantiation which is now complete.
27660 (Analyze_Package_Instantiation): No instantiated body is needed if the
27661 main unit is generic. Efficient, and avoid anomalies when a instance
27662 appears in a package accessed through rtsfind.
27664 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27666 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
27667 do not generate a declaration for a temporary if the call is part of a
27668 library-level instantiation.
27670 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27672 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
27673 searching for a limited component to flag.
27675 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
27676 expansion of Input, to account for the fact that the implicit call
27677 generated by the attribute reference must freeze the user-defined
27678 stream subprogram. This is only relevant to 'Input, because it can
27679 appear in an object declaration, prior to the body of the subprogram.
27681 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
27682 expansion can proceed and further errors uncovered.
27683 (Minor clean up): Fix cases of using | instead of \ for continuation
27686 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27688 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
27690 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
27691 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
27692 Use gcc_assert and gcc_unreachable.
27694 * decl.c (gnat_to_gnu_entity, case object): Check and process a
27695 specified alignment before validating size.
27696 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
27697 stripped-down declaration for the type of the inner field when making
27700 * utils.c (finish_record_type): Do not compute the size in units
27701 incrementally. Instead compute it once for the rep clause case.
27702 Use gcc_assert and gcc_unreachable.
27704 2004-10-04 Vincent Celier <celier@gnat.com>
27706 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
27708 (Is_Valid_Path_Name): Take '/' as a directory separator.
27710 2004-10-04 Vincent Celier <celier@gnat.com>
27712 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
27713 (Extended_Project) only if Extended_Project is defined, to avoid
27715 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
27717 (Parse_Single_Project): Ditto.
27719 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
27720 Add_To_Project_Path for virtual projects.
27722 2004-10-04 Vincent Celier <celier@gnat.com>
27724 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

27728 parameter Options_2.
27730 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
27731 Build_Dynamic_Library with an empty Options_2.
27733 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
27736 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
27737 directory separator, if any.
27738 (Gprmake): Do not allow mains on the command line for library projects.
27739 Do not attempt to link when the project is a library project.
27740 (Library_Opts): New table to store Library_Options.
27741 (Build_Library): If Library_Options is specified, pass these options
27742 when building a shared library.
27744 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
27746 * s-tposen.adb (Service_Entry): The object must be always unlocked at

27766 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
27767 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
27768 used to signal whether the compiler creates the required stacks and
27769 descriptors for the different tasks (when True) or it is done by the
27770 underlying operating system at run time (when False).
27771 It is initially set to False in all targets.
27773 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
27774 if it is supported by the target.
27775 (Make_Task_Create_Call): Pass the stack address if it has been
27776 previously created. Otherwise pass a Null_Address.
27778 * snames.adb: Add _stack.

27781 statically allocated task stacks.
27783 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
27784 Stack_Address argument.
27785 Check that its value is equal to Null_Address because this target does
27786 not support the static stack allocation.
27788 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
27790 * usage.adb: Change "pragma inline" to "pragma Inline" in information
27793 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
27795 * exp_dist.adb: Split declaration of asynchronous flag out of
27796 Add_RACW_Read_Attribute.
27797 Minor reformatting for better alignment with PolyORB version.
27798 Store the entity for the asynchronous flag of an RACW, rather than the
27799 expression, in the asynchronous flags table. This will allow this flag
27800 to be used in other subprograms beside Add_RACW_Read_Attribute.
27802 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
27804 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

27808 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
27809 sockets constant MSG_NOSIGNAL (Linux-specific).
27810 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
27811 all Send operations.
27812 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
27813 from trigerring SIGPIPE.
27814 Rename components to avoid clash with Ada 2005 possible reserved
27816 (Check_Selector): When the select system call returns with an error
27817 condition, propagate Socket_Error to the caller.
27819 2004-10-01 Jan Hubicka <jh@suse.cz>
27821 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

27829 Change "pragma inline" to "pragma Inline" in information and error
27831 Minor reformatting.
27833 * freeze.adb (Check_Address_Clause): Remove previous change, not the
27834 right way of doing things after all.
27835 (Freeze_Entity): For object, set Is_Public for imported entities
27836 unless there is an address clause present.
27838 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
27840 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
27841 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
27842 ensures proper handling of types with rep clauses, which might have
27843 their TYPE_SIZE set already.
27845 2004-09-21 Robert Dewar <dewar@gnat.com>
27847 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
27848 packed array types in both little- and big-endian cases. This change
27849 ensures that we no longer count on the unused bits being initialized
27850 for such types (and in particular ensures that equality testing will
27851 only read the relevant bits).
27852 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
27853 These changes mean that we no longer need to initialize small packed
27855 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
27856 optimization to an LJM field as to its parent field.
27858 * ada-tree.h, trans.c, utils.c, utils2.c:

27861 2004-09-20 Jan Hubicka <jh@suse.cz>
27863 * utils.c (gnat_finalize): Remove.
27864 (end_subprog_body): Directly call cgraph_finalize_function;
27865 do not lower the nested functions.
27867 2004-09-20 Robert Dewar <dewar@gnat.com>
27870 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
27871 if an address clause is present, since that means that the Import
27874 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
27876 * 5tsystem.ads: Removed, no longer used.
27878 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>

27900 an existing directory.
27901 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
27902 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
27903 Convert the result to File_Size.
27905 * prj.ads: (Project_Error): New exception
27907 * prj-attr.adb: Except in procedure Initialize, Fail comes from
27908 Prj.Com, not from Osint.
27909 (Attrs, Package_Attributes): Tables moved to private part of spec
27910 (Add_Attribute, Add_Unknown_Package): Moved to new child package

27913 Prj.Project_Error after call to Fail.
27914 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
27915 Fail. Check that package name is not already in use.
27917 * prj-attr.ads: Comment updates to indicate that all subprograms may be
27918 used by tools, not only by the project manager, and to indicate that
27919 exception Prj.Prj_Error may be raised in case of problem.
27920 (Add_Unknown_Package, Add_Attribute): Moved to new child package
27922 (Attrs, Package_Attributes): Table instantiations moved from the body to

28036 contains the required machinery for handling that.
28038 * sem_util.ads: Change comment associated to procedure
28039 Check_Potentially_Blocking_Operation.
28040 This procedure does not insert a call for raising the exception because
28041 that is currently done by the run time.
28043 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
28045 * init.c: Add the global variable __gl_detect_blocking that indicates
28046 whether pragma Detect_Blocking is active (1) or not (0). Needed for
28047 making the pragma available at run time.
28048 (__gnat_set_globals): Pass and update the detect_blocking parameter.

28095 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
28096 Asynchrronous that applies to a remote access-to-subprogram type, mark
28097 the underlying RACW type as asynchronous.
28099 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and

28112 a component declaration must remain attached at that point in the
28113 tree so New_Copy_Tree copies it if the enclosing record type is derived.
28114 It is therefore necessary to take a copy of the expression when building
28115 the corresponding assignment statement in the init proc.
28116 As a side effect, in the case of a derived record type, we now see the
28117 original expression, without any rewriting that could have occurred
28118 during expansion of the ancestor type's init proc, and we do not need
28119 to go back to Original_Node.

28129 subprogram. The proxy object is used as the designated object
28130 for RAS values on the same partition (unless All_Calls_Remote applies).
28131 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
28132 System.Partition_Interface.Get_Unique_Remote_Pointer.

28137 New implementation of expansion for remote access-to-subprogram types,
28138 based on the RACW infrastructure.
28140 * exp_dist.ads (Copy_Specification): Update comment to note that this
28141 function can copy the specification from either a subprogram
28142 specification or an access-to-subprogram type definition.

28151 add a polling call if the subprogram is to be inlined by the back-end,
28152 to avoid repeated calls with multiple inlinings.
28154 * checks.adb (Apply_Alignment_Check): If the expression in the address
28155 clause is a call whose name is not a static entity (e.g. a dispatching
28156 call), treat as dynamic.

28322 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
28323 target names rewrite to fix regressions with recent version of

28377 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
28378 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
28379 option and not mdll anymore. Update comment.
28381 2004-08-16 Pascal Obry <obry@gnat.com>
28383 * bld.adb (Put_Include_Project): Properly handle directory separators

28401 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
28402 for a global aliased object with a variable size and an unconstrained
28403 nominal subtype, pretend there is no initializer if the one we have is
28404 incomplete, and avoid referencing an inexistant component in there. The
28405 part we have will be rebuilt anyway and the reference may confuse

28428 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
28429 unit, this is an attempt to inline a construct that is not available in
28430 the current restricted mode, so abort rather than trying to continue.
28432 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
28433 discriminants that rename those of the parent, recover names of
28434 original discriminants for the constraint on the full view of the
28436 (Complete_Private_Subtype): Do not create a subtype declaration if the
28437 subtype is an itype.
28439 * gnat_rm.texi: Added section on implementation of discriminated
28440 records with default values for discriminants.

28465 returning C.int, to avoid using a derived boolean type.
28467 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

28496 ignore overflows on low and high bounds of an index to also account for
28497 differences in signedness between sizetype and gnu_index_subtype.
28498 These are as legitimate as the ones caused by a lower TYPE_PRECISION
28501 2004-08-09 Robert Dewar <dewar@gnat.com>

28598 the parent initialization procedure for derived Unchecked_Unions.
28599 Instead, derived Unchecked_Unions build their own initialization
28601 (Build_Variant_Record_Equality): Implement Unchecked_Union equality.
28602 Check the body of the subprogram for details.
28603 (Freeze_Record_Type): Prevent the inheritance of discriminant checking

29165 for a renaming, stabilize the initialization expression if we are at a

29224 when Keep_Temporary_Files is False.
29225 (GNATCmd): When not on VMS, and the GNAT driver has been invoked with
29226 directory information, add the directory in front of the path.
29227 When not on VMS, handle new switch -dn before the command to set
29228 Keep_Temporary_Files to True.
29229 (Non_VMS_Usage): Use lower case for the non VMS usage: this is valid

30421 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

31125 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
31126 overriding, use the operation of the parent unconditionally.
31128 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
31129 operation when either operand is a literal, to avoid further
31132 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and

32415 complete assignment subtree which is now unnecessary, as the expansion
32416 of inlined call has been improved to preserve a consistent assignment
32417 tree. Note_Possible_Modification must be called only
32418 after checks have been applied, or else unnecessary checks will

32679 * osint.adb (Executable_Prefix): Set Exec_Name to the current
32680 executable name when not initialized. Otherwise, use its current value.
32682 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
32683 initialize it to another executable name than the current one. This
32684 allows to configure paths for an executable name (gnatmake) different
32685 from the current one (gnatdist).
32687 2004-03-29 Ed Schonberg <schonberg@gnat.com>
32689 * exp_ch6.adb (Expand_Call): A call to a function declared in the
32690 current unit cannot be inlined if it appears in the body of a withed
32691 unit, to avoid order of elaboration problems in gigi.
32693 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
32694 information for protected (wrapper) operation as well, to simplify gdb
32697 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
32698 protected body, indicate that the entity for the generated spec comes
32699 from source, to ensure that references are properly generated for it.

32736 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
32737 attribute reference does not denote a subtype, it can be any
32738 expression that has a classwide type, potentially after an implicit
32739 dereference. In particular, the prefix can be a view conversion for
32740 a classwide type (for which Is_Object_Reference holds), but it can
32741 also be a value conversion for an access-to-classwide type. In the
32742 latter case, there is an implicit dereference, and the original node
32743 for the prefix does not verify Is_Object_Reference.
32745 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
32746 conversion of a discriminant-dependent component of a mutable object
32749 2004-03-25 Ed Schonberg <schonberg@gnat.com>
32751 * freeze.adb (Freeze_Entity): When an inherited subprogram is
32752 inherited, has convention C, and has unconstrained array parameters,
32753 place the corresponding warning on the derived type declaration rather
32754 than the original subprogram.

32770 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
32771 value expressions to ensure that calls within a component definition
32772 will be checked (since those are evaluated during the record type's

32824 declaration for a child subprogram body that acts as a spec, indicate
32825 that the entity in the declaration needs debugging information.
32827 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
32828 full view if the subtype is created for a constrained record component;
32829 gigi has enough information to construct the record, and there is no
32830 place in the tree for the declaration.
32832 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
32833 serial number for the dummy body that is built for analysis, to avoid
32834 inconsistencies in the generation of internal names when compiling

32871 Minor reformatting.
32873 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
32875 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
32876 as regular exception objects and not as mere integers representing the
32877 condition code. The latter approach required some dynamics to mask off
32878 severity bits, which did not fit well into the GCC table based model.
32879 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
32880 exception data objects. We don't it and it would conflict with the other
32881 external symbol we have to generate for such exceptions.
32883 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
32884 the special code for VMS exceptions, since these are now represented
32885 as regular exceptions objects.

32928 When needed (stack checking) the stack size is retrieved
32929 from the VxWorks kernel.
32931 * Makefile.in: Flag -nostdinc is required when building the run time
32932 for avoiding looking for files in the base compiler.
32933 Add the VxWorks specific version of the package body for
32934 System.Stack_checking.Operations (5zstchop.adb).
32936 * Make-lang.in: Add the object file for
32937 System.Stack_Checking.Operations.

32962 the procedures Add_To_Path_File.
32963 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
32964 making sure that each directory is present only once and, for object
32965 dirs, when a directory already present is added, the duplicate is
32966 removed and the directory is always put as the last in the table.
32967 Write the path files at the end of these accumulations.

33179 explicit dereference.
33180 (Expand_N_Slice): Same. Always do the rewriting, even for the case
33181 of non-packed slices, since the dereference action generated by

33184 analyze and resolve the rewritten explicit dereference so it is seen
33186 (Insert_Dereference_Action): This procedure is now called only for the

34028 No_Requeue_Statements.
34030 * s-rident.ads: Adding restriction No_Requeue_Statements (AI-00249)

34032 kept for backward compatibility.
34034 2004-02-02 Ed Schonberg <schonberg@gnat.com>
34036 * lib.ads, i-cobol.ads, * s-stoele.ads, s-thread.ads, style.ads,

34063 * utils.c (create_field_decl): Augment the head comment about bitfield
34064 creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
34065 here, because the former is not accurate enough at this point.
34066 Let finish_record_type decide instead.
34067 Don't make a bitfield if the field is to be addressable.
34068 Always set a size for the field if the record is packed, to ensure the
34069 checks for bitfield creation are triggered.
34070 (finish_record_type): During last pass over the fields, clear
34071 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
34072 not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P
34073 from DECL_BIT_FIELD.

34530 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
34531 N_String_Literal node always references an E_String_Literal_Subtype
34532 entity. This may not be true in the future.
34533 (Possible_Bit_Aligned_Component): Move processing of
34534 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
34536 * exp_ch6.adb (Expand_Thread_Body): Pick up
34537 Default_Secondary_Stack_Size as variable so that we get value modified
34538 by possible -Dnnn binder parameter.
34540 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
34541 (Type_May_Have_Bit_Aligned_Components): New function.

34554 call to non-pure imported function getting eliminated.

34557 gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,

34581 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
34582 ineffective elaborate all pragmas on non-visible packages (this
34583 happened when a renamed subprogram was called). Now the elaborate all
34584 always goes on the package containing the renaming rather than the one
34585 containing the renamed subprogram.
34587 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
34588 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

34843 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
34844 bounds of a loop, create a separate block in order to generate proper
34845 cleanup actions to prevent memory leaks.
34847 * sem_res.adb (Resolve_Call): After a call to
34848 Establish_Transient_Scope, the call may be rewritten and relocated, in

34869 * 7sintman.adb: Minor reformatting
34871 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
34872 standard linker options to get standard libraries linked. We now plan

34874 configurable run-time (e.g. if a library is not needed at all, provide
34875 a dummy empty library).
34877 * targparm.ads: Configurable_Run_Time mode no longer affects linker
34878 options (-L parameters and standard libraries). What we plan to do is
34879 to provide dummy libraries where the libraries are not required.
34881 * gnatbind.adb: Minor comment improvement

34893 of aggregate with default initialized components.
34894 (Has_Default_Init_Comps): Improve implementation to recursively check
34895 all the present expressions.
34897 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
34898 to indicate that the initialization call corresponds to a
34899 default-initialized component of an aggregate.
34900 In case of default initialized aggregate with tasks this parameter is
34901 used to generate a null string (this is just a workaround that must be
34902 improved later). In case of discriminants, this parameter is used to
34903 generate a selected component node that gives access to the discriminant
34906 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
34907 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
34908 allocated aggregates with default-initialized components.
34910 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
34911 the box notation is used in positional aggregates.

34953 Process nodes N_Comment.
34955 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
34956 without comments and there are some comments, set the flag
34957 Unkept_Comments to True.

34999 Correct typo in comment
35000 (Resolve_Aggregate): In case of array aggregates set the estimated

35049 unwind past it. Update the copyright notice.
35051 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
35053 * a-elchha.ads: New file.

36507 Remove the test against being in No_Run_Time_Mode before generating a
36508 call to Register_Tag. It is redundant with the test against the
36509 availability of the function Register_Tag.

38452 used elsewhere. This fixes the problem of the back end not
38453 realizing we were clever enough to see that this was
38455 (Expr_Val): Remove call to Constant_Array_Ref
38456 (Expr_Rep_Val): Remove call to Constant_Array_Ref
38458 (Constant_Array_Ref): Deal with string literals (patch
38459 suggested by Zack Weinberg on the gcc list)

38712 rule which was mandated by code generation issues.
38714 * gnat-style.texi (header): Add @dircategory, @direntry.
38715 (title page): Remove date.
38716 (general) Add @./@: where approriate, and two spaces after the
38717 full stop at the end of a sentence. Use @samp markup when
38718 referring concrete lexical entities (keywords, attribute names
38719 etc.), and @syntax for ARM grammar elements. Use @r for English

38734 * make.adb (Add_Switch): Make Generic_Position a procedure. The
38735 function approach did not work well because of a side effect (the
38736 function call could reallocate the table which was being indexed
38737 using its result). Fixes ada/4851.

38775 * raise.c (__gnat_eh_personality): Exception handling personality
38776 routine for Ada. Still in rough state, inspired from the C++ version
38777 and still containing a bunch of debugging artifacts.
38778 (parse_lsda_header, get_ttype_entry): Local (static) helpers, also
38779 inspired from the C++ library.
38781 * raise.c (eh_personality): Add comments. Part of work for the GCC 3
38782 exception handling integration.

38793 2001-12-19 Robert Dewar <dewar@gnat.com>
38795 * a-ngelfu.adb: Remove ??? comment for inappropriate Inline_Always
38796 Add 2001 to copyright date
38798 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
38799 need to force universal inlining for these cases.
38801 2001-12-19 Arnaud Charlet <charlet@gnat.com>
38803 * s-taprob.adb: Minor clean ups so that this unit can be used in
38806 * exp_ch7.adb: Allow use of secondary stack in HI mode.
38807 Disallow it when pragma Restrictions (No_Secondary_Stack) is specified.

38829 discriminant check if the selected component is a component of
38830 the argument of an initialization procedure.
38832 * trans.c (tree_transform, case of arithmetic operators): If result
38833 type is private, the gnu_type is the base type of the full view,
38834 given that the full view itself may be a subtype.

39104 2001-12-17 Laurent Pautet <pautet@gnat.com>
39107 Fix comment of Shutdown_Socket and Close_Socket. These functions
39108 should not fail silently because if they are called twice, this
39109 probably means that there is a race condition in the user program.
39110 Anyway, this behaviour is consistent with the rest of this unit.
39111 When an error occurs, an exception is raised with the error message
39112 as exception message.

40441 (GNATMAKE_RTL_OBJS): add g-crc32.o
40444 (CRC_Match): new function.
40445 (Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
40446 instead of the previous simple checksum algorithm.
40447 (Time_Stamp_Mismatch): use CRC_Match for comparison.
40448 (Set_Source_Table): idem.
40451 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
40452 instead of simple checksum.
40453 (CRC_Match): new function.
40454 (CRC_Error): new constant.
40456 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
40457 a CRC now and not a simple checksum. A CRC uses lower-case hex
40458 letters, fixes ambiguity in parsing.
40460 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
40461 is what this variable will store.
40463 * bcheck.adb: Change reference to chechsum in comments by CRC.
40464 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
40465 rename All_Checksum_Match to All_CRC_Match. Change due to API
40466 renaming since now GNAT does not use a simple checksum but a
40467 CRC using GNAT.CRC32.
40469 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
40470 now and not anymore a simple checksum.
40472 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
40475 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
40478 (Restore_Scan_State): rename Checksum to CRC.
40479 (Save_Scan_State): idem.
40483 (Checksum): rename to CRC.
40484 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
40486 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
40487 GNAT.CRC32). Update copyright notice.
40489 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
40490 GNAT.CRC32). Update copyright notice.
40493 (Accumulate_Checksum): removed.
40494 (Update): new procedure. Add a wide-character into the CRC.
40497 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
40498 (Load_File): fix initialization of S (change Source_Checksum to
40501 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
40502 Source_CRC in S initialization.
40504 * sinput.adb (Source_Checksum): renamed to Source_CRC.
40506 * sinput.ads (Source_Checksum): renamed to Source_CRC.
40507 Update comments for the CRC.
40509 * types.adb (Hex): Use lowercase for the letter part.
40511 * types.ads (Get_Hex_String): Returns the hexadecimal representation
40512 for a word. This is currently used only for CRC. In previous version,
40513 the checksum was using a representation with all letter being
40514 upper-case. With the new implementation (using CRC) we do not remove
40515 the 32th bit of the CRC, so we can have an upper-case starting letter
40516 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
40517 It is ambigous since the CRC was optional and could be followed by
40518 options like EB, EE. So now this routines uses lower-case letter for
40519 the hexadecimal representation. Strange enough only lower case letters
40520 where checked in Scan_ALI (even if this was not a possible case).
40522 * gnatvsn.ads (Library_Version): changed to 3.15a.
40524 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
40527 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
40530 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
40531 Add 2001 to copyright notice
40532 (Accumulate_Checksum): Modify to use System.CRC32.
40534 * ali-util.ads: Redo changes of previous revision to continue to use
40535 the word Checksum. Add 2001 to copyright notice.
