1336 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
1337 convention from its base type, do not set the type to that of integer,

1404 New local subprogram Is_Valid_Remote_Object_Type, replaces

1416 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
1417 Is_Remote_Call_Interface to identify RACW types in a stable and
1418 consistent way. We used to rely in this predicate on the privateness of
1419 the designated type and its ancestors, but depending on the currently
1420 visible private parts, this caused false negatives. We now uniformly
1421 rely on checks made at the point where the RACW type is declared.

1435 Add missing escaping of all-caps word 'CPP' in error messages.
1436 (Build_Discriminated_Subtype): Do not inherit representation clauses
1437 from parent type if subtype already carries them, because they are
1438 inherited earlier during derivation and already include those that may
1439 come from a partial view.
1441 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
1442 Check the declarations of a subprogram body for proper deferred

1477 operation of an RACW stub type (these primitives are only executed
1478 through dispatching, never through static calls).
1479 (Collect_Interps): When only one interpretation has been found, set N's
1480 Entity and Etype to that interpretation, otherwise Entity and Etype may
1481 still refer to an interpretation that was ignored by Add_One_Interp,
1482 in which case would end up with being marked as not overloaded but with
1483 an Entity attribute not pointing to its (unique) correct interpretation.

1542 equivalent representation, but has the advantage of allowing
1543 compilation of this file under 64 bits platforms.

5742 subprogram body that acts as its own spec may not have a non-private
5743 WITH clause on a private sibling.
5744 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
5745 child unit is a renaming, create an implicit with_clause on that
5746 parent, and not on the unit it renames, to prevent visibility errors

5806 (Find_Primitive_Operation): Handle case of class-wide types.
5807 (Analyze_Overloaded_Selected_Component): If type of prefix is
5808 class-wide, use visible components of base type.

5811 formal of a generic subprogram. find candidate interpretations by
5812 scanning the list of generic formal declarations.:
5813 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
5814 type from a limited_with_clause, and the full view is available, use it
5815 for subsequent semantic checks.

5843 Gary Dismukes <dismukes@adacore.com>
5845 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
5846 requeue statement is dispatching. Do not emit an error when the name is
5847 not an entry and the context is a dispatching select. Add code to
5848 perform subtype conformance between the formals of the current entry
5849 and those of the target interface primitive.
5850 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
5851 Timed_Entry_Call): Analyze the triggering statement as the first step of
5852 the processing. If this is a dispatching select, postpone the analysis
5853 of all select statements until the Expander transforms the select. This
5854 approach avoids generating duplicate identifiers after the Expander has
5855 replicated some of the select statements. In case the Expander is
5856 disabled, perform regular analysis.
5857 (Check_Triggering_Statement): New routine.
5858 (Analyze_Requeue): Exclude any interpretations that are not entries when
5859 checking overloaded names in a requeue. Also test type conformance for
5860 matching interpretations rather than requiring subtype conformance at
5861 that point to conform with the RM's resolution rule for requeues.

5865 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
5866 inherited operation is a defaulted tag-indeterminate call, and there is
5867 a statically tagged actual, use the static tag as a controlling actual
5868 for the defaulted actual.
5870 2007-12-13 Geert Bosch <bosch@adacore.com>
5872 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static
5873 context, so do not call Check_Non_Static_Context.

5897 latest Ada 2005 rules about renaming and 'Access of
5898 discriminant-dependent components.

6454 Add support for parsing multiple array index types info, or
6455 multiple inherited interfaces info. This information cannot be stored
6456 in Xref_Entity_Record, which only supports a single instance of Tref_*,

6472 Dismukes). After this patch there is no need to perform any
6473 additional management on these nodes in Expand_Interface_Actuals.
6475 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
6476 that handles use of 'Access and 'Unchecked_Access applied to
6477 actuals covering interface types. Such code is now
6478 centralized in Expand_N_Attribute_Reference.

6522 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
6523 used by VxWorks targets to have access to task-specific data and be
6524 able to extract the stack boundaries for stack checking.

6568 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
6569 association for an access component, add an association with null as
6570 the expression. Remove testing for array subtypes and the setting in
6571 that case of Ctyp to the array component type, which prevented proper
6572 inclusion of an association for null-initialized arrays. Collapse
6573 condition that tests for array subtypes into just a test of
6574 Is_Partially_Initialized_Type (which already covers arrays anyway).

6591 * sem_ch4.adb: Minor code and comment reformatting.
6592 (Analyze_Allocator): When the designated type of an unconstrained
6593 allocator is a record with unknown discriminants or an array with

6760 Add a section on leap seconds control along with two entities used to
6761 enable and disable leap seconds support. The array Leap_Second_Times is
6762 now constant and contains hard time values pre-generated. Remove

6824 Eric Botcazou <ebotcazou@adacore.com>
6827 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
6828 indirection added to the HT_Link component of the TSD. This is required
6829 to statically allocate the TSD.
6832 Minor reordering of the declarations in the private part. Required to
6833 add a level of indirection to the contents of the TSD component HT_Link.
6834 This is required to statically allocate the TSD.
6836 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
6837 Is_Statically_Allocated set from constant objects.
6838 Do not make exported constants created by the compiler volatile.
6839 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
6842 * trans.c (Identifier_to_gnu): For constants, unshare initializers
6843 before returning them.
6845 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
6846 public part of the package.
6847 (Make_DT): Move HT_Link component out of the TSD record. For this
6848 purpose Make_DT now declares a separate object that stores the
6849 HT_Link value, and initializes the TSD component with the address
6850 of this new object. The addition of this level of indirection is
6851 required to statically allocate the TSD because the TSD cannot
6852 have variable components.
6853 (Expand_Interface_Conversion): Improve the expanded code.
6854 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
6856 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
6857 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
6858 if we are building static dispatch tables then we must not generate
6859 extra code to register the primitive because the dispatch table will
6860 be built at the end of the library package; otherwise we notify that
6861 we cannot build the static dispatch table.
6863 2007-09-26 Robert Dewar <dewar@adacore.com>
6865 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

6880 for thunks associated with interface types.
6882 * einfo.ads: Improve documentatation of Is_Internal
6883 (Is_Thunk): New attribute applicable to subprograms. True for thunks
6884 associated with interface types.
6885 Extensive comment fixes regarding flags that appear in all entities. The
6886 documentation is now consistent for all such flags (there were a number
6887 of errors in the documentation in this regard).
6889 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
6891 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
6892 of these procedures are passed a function call that already has
6893 build-in-place actuals (testing new flag
6894 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
6895 the case where processing continues.
6896 (Expand_Call): If the call is generated from a thunk body then we
6897 propagate the extra actuals associated with the accessibility
6898 level of the access type actuals.
6900 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
6901 of each extra formal of a protected operation to reference the
6902 corresponding extra formal of the subprogram denoted by the
6903 operation's Protected_Body_Subprogram.
6905 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
6906 N_Function_Call nodes.
6908 2007-09-26 Robert Dewar <dewar@adacore.com>
6910 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
6912 * debug.adb: Add d.s flag.

6916 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
6917 debug variable so that it won't be initialized when pragma
6918 Initialize_Scalars is in effect.
6920 2007-09-26 Gary Dismukes <dismukes@adacore.com>
6922 * freeze.adb (Freeze_Entity): Remove check for preelaborable
6923 initialization of a full view. This is moved to
6924 Analyze_Package_Specification.
6926 * sem_ch7.adb (Analyze_Package_Specification): Add check for
6927 preelaborable initialization of a full view in entity loop.
6928 (Uninstall_Declarations): If entity is a use-visible compilation unit,
6929 its child units are use-visible only if they are visible child units.
6931 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
6932 whether an expression can be used within a type declaration that
6933 requires preelaborable init.
6934 (Check_Components): Replace inline code that does partial checking for
6935 preelaborable default expressions with call to
6936 Is_Preelaborable_Expression.
6937 (Has_Preelaborable_Initialization): In the case of a generic actual
6938 subtype, (that is, Is_Generic_Actual is True), return the result of
6939 applying Has_Preelaborable_Initialization to the generic actual's base
6942 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
6944 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
6945 call to Jan_1_Day _Of_Week to optimize its performance.
6946 (Is_Leap): Move the routine to the scope of Week_In_Year.
6947 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
6948 weekday on which January 1 falls of Year - 1 and Year + 1. This function
6949 avoids calling Time_Of and Split, thus making it more efficent.
6950 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
6952 * g-calend.ads (Week_In_Year): Change comment to reflect new
6955 2007-09-26 Emmanuel Briot <briot@adacore.com>

6958 Command_Line): New types
6959 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
6960 support for defining how switches can be grouped on a command line (as
6961 is the case for -gnatw... for GNAT), and how simple switches can be
6962 used as aliases for more complex switches (-gnatwa is same as
6964 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
6965 (Start, Current_*): New subprograms
6966 Added support for parsing an array of strings in addition to the real
6968 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
6969 be moved from the body to the private part of the spec.
6970 (*): All subprograms now have an extra parameter with default value to
6971 specify which parser should be used. For backward compatibility, it
6972 defaults to parsing the command line of the application. They were also
6973 modified to properly handle cases where each of the argument does not
6974 start at index 1 (which is always true for Ada.Command_Line, but not
6975 when processing any Argument_List).
6976 (Free): New subprogram
6977 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
6978 Argument): New subprograms
6979 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
6980 special characters like ':', '=',... are now handled in a single place,
6981 which makes the code more extensible eventually.
6982 (Getopt, Full_Switch): When the switch was returned as part of the
6983 special character '*', make sure it is prepended by the switch character
6984 ('-' in general), so that the application knows whether "foo" or "-foo"
6985 was specified on the command line.
6987 2007-09-26 Florian Villoing <villoing@adacore.com>
6989 * g-dirope.adb (Remove_Dir): In case we are removing directories
6990 recursively, make sure that if an exception is raised during the
6991 processing, the current working directory is reset to its initial
6992 value before propagating the exception.
6994 2007-09-26 Vincent Celier <celier@adacore.com>
6996 * gnatbind.adb: If there are several ALI files specified and there is
6997 a main program to bind, the first ALI is expected to contain the main
6998 subprogram and the names of the binder generated files will be derived
6999 from the first ALI file name.
7000 (Gnatbind): Fix insertion character in invocation of Error_Msg
7002 2007-09-26 Vincent Celier <celier@adacore.com>
7004 * gnatcmd.adb (Check_Files): Do not include sources that have been
7005 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
7007 2007-09-26 Ed Schonberg <schonberg@adacore.com>
7009 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
7010 information about each of its index types, following the type
7011 reference for its component type.
7013 2007-09-26 Vincent Celier <celier@adacore.com>
7015 * make.adb: (Kill): New procedure (__gnat_kill imported)

7026 2007-09-26 Vincent Celier <celier@adacore.com>
7028 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
7030 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
7031 Replace components Compiler_Min_Options and Binder_Min_Options with
7032 Compiler_Required_Switches and Binder_Required_Switches in record

7037 * prj-attr.adb: New attributes Required_Switches (<language>) in
7038 packages Compiler and Binder.
7040 * prj-nmsc.adb: Major rewrite of the processing of configuration
7041 attributes for gprbuild. No impact on GNAT tools.
7043 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer

7075 2007-09-26 Ed Schonberg <schonberg@adacore.com>
7077 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
7078 ancestor of the derived type, the operations are inherited from the
7079 primary dispatch table of the parent.
7080 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
7081 when the context is an explicit type conversion.
7083 2007-09-26 Ed Schonberg <schonberg@adacore.com>

7383 potentially be called.
7384 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
7385 body for 'Output when the type is abstract (only the creation of the
7386 body for 'Input is excluded when the type is abstract).

7388 statement, so that False will be returned for TTS_Stream_Input if the
7389 associated tagged type is an abstract extension. Add comments for

7392 variable, insert init proc call only after the shared variable
7393 procedures have been processed, because the IP call needs to undergo

7395 procedures to be available (and elaborated).

7407 type, retrieve its value from the aggregate itself, where it must have
7410 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
7411 to remove other spurious ambiguities on arithmetic operations involving
7412 literals and addresses, on systems where Address is a visible integer
7413 type, when the operator is called in functional notation.

7540 (Write_Entity_Flags): Write the status of flag Is_Raised.
7541 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
7542 spurious ambiguities when integer literals appear in the context of an
7543 address type that is a visible integer type.
7545 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
7546 exceptions never being raised.

7563 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
7564 library-level package renaming, pass the declaration associated with
7565 the renaming's special debug variable to Qualify_Entity_Names to ensure
7566 that its encoded name is properly qualified.
7568 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
7569 occurring in the list of entities to qualify, and do not attempt to
7570 traverse an entity list in that case. Variables associated with
7571 ` library-level package renamings can now occur in the table.
7573 * exp_dbug.ads: Revise documentation of the encoding for renaming

7590 to include loop parameters.
7591 (Valid_Conversion): Avoid generation of spurious error message.

7595 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
7596 concatenations of string literals into a single literal, in order to
7597 avoid very deep recursion in the front end, which was causing stack
7600 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
7601 string, and the right operand is a string literal (the case of "" &
7602 "..."), optimize by avoiding copying the right operand -- just use the
7603 value of the right operand directly.
7605 * stringt.adb (Store_String_Chars): Optimize by growing the
7606 String_Chars table all at once, rather than appending characters one by
7608 (Write_String_Table_Entry): If the string to be printed is very long,
7609 just print the first few characters, followed by the length. Otherwise,
7610 doing "pn(n)" in the debugger can take an extremely long time.
7612 * sem_prag.adb (Process_Interface_Name): Replace loop doing
7613 Store_String_Char with Store_String_Chars.

7630 2007-08-31 Ed Schonberg <schonberg@adacore.com>
7632 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
7633 flag, for effiency. It is called when analyzing arithmetic operators
7634 and also for actuals in calls that are universal_integers. The flag is
7635 set for the predefined type address, and for any type or subtype
7638 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
7639 Universal_Integer, when the formal is a descendent of address and the
7640 call appears in user code.

7707 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
7708 associated with Standard_Debug_Renaming_Type, to be used as the type of
7709 the special variables whose names provide debugger encodings for
7710 renaming declarations.
7712 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.

7720 (Debug_Renaming_Declaration): Replace creation of an enumeration type
7721 and literal with creation of a variable of type
7722 Standard_Debug_Renaming_Type whose name encodes both the renamed object

7732 Ed Schonberg <schonberg@adacore.com>
7733 Javier Miranda <miranda@adacore.com>
7735 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
7736 ancestor part given by an aggregate to test for an unchecked conversion,
7737 since this can occur in some cases when the ancestor part is a function
7738 call, and we don't want to fall into the recursive call to this
7739 procedure in that case.
7741 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
7742 stream attributes on limited types to account for user-specified
7743 attributes as well as whether Input (resp. Output) becomes available
7744 due to Read (resp. Write) being available for the type. Change Boolean
7745 variable to the more accurate name
7746 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
7747 double-"not" predicate at beginning of return statement to more
7748 understandable form.
7750 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
7751 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
7752 in a block statement and use that as the first statement of the
7753 expanded return rather than incorrectly using the handled sequence as
7754 the first statement.
7756 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
7757 operation, generate an explicit freeze node for it rather than
7758 generating extra formals, to ensure that gigi has the proper order of
7759 elaboration for anonymous subtypes in the signature of the subprograms.
7760 (Build_In_Place_Formal): Move assertion to beginning of loop.
7761 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
7762 applied to a function call (occurs for some cases of 'Input).

7764 applied to a function call (occurs for some cases of 'Input).
7766 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
7767 2005, generate an extended return statement enclosing the result object
7770 * freeze.adb (Freeze_Record_Type): Extend the current management of
7771 components that are access type with an allocator as default value: add
7772 missing support to the use of qualified expressions of the
7773 allocator (which also cause freezing of the designated type!)
7774 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
7775 dispatching operation, since extra formals may be needed by calls to
7776 build-in-place functions (such as stream 'Input).
7778 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
7779 formals for 'Constrained and accessibility level in the case of a
7780 predefined dispatching operation.
7782 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
7783 point, no need to find the parent node.
7785 2007-08-16 Javier Miranda <miranda@adacore.com>
7787 * exp_attr.adb (Attribute_Priority): Add missing support for entries
7790 2007-08-16 Javier Miranda <miranda@adacore.com>
7792 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
7793 is not really required and can introduce regression with the debugger.
7794 The original problem is fixed with the patch written for checks.adb.
7796 2007-08-16 Thomas Quinot <quinot@adacore.com>
7798 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

7806 Including_Non_Switch set to False.
7808 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
7809 parameter Including_Non_Switch, defaulted to True. When
7810 Including_Non_Switch is False, options that are not switches and

7829 and C also has a with clause for P in its body.
7830 (Has_Limited_With_Clause): New routine.
7831 (Has_With_Clause): New routine.
7833 2007-08-16 Ed Schonberg <schonberg@adacore.com>
7835 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
7836 generic for an enclosing instance is a global reference, even though
7837 its scope is the enclosing instance.

7840 Javier Miranda <miranda@adacore.com>
7842 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to

7860 Bob Duff <duff@adacore.com>
7861 Nicolas Setton <setton@adacore.com>
7863 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
7864 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
7865 the statement which is being resolved comes from a predefined library
7866 unit, all non-predefined library interpretations are skipped.
7867 (Resolve_Op_Concat): If string concatenation was folded in the parser,
7868 but the "&" is user defined, give an error, because the folding would
7871 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
7872 the parser has folded a long sequence of concatenations of string

7876 and "JMP_BUF" variables as artificial.
7877 (N_String_Literal): Do not use alloca for very long string literals. Use

7931 needed for access to concurrent record types generated by the expander.
7932 (Generate_Range_Check): When generating a temporary to capture the
7933 value of a conversion that requires a range check, set the type of the
7934 temporary before rewriting the node, so that the type is always
7935 properly placed for back-end use.
7936 (Apply_Float_Conversion_Check): Handle case where the conversion is
7938 (Get_Discriminal): Code reformatting. Climb the scope stack looking

7957 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
7958 aggregate code before allocator, and ahead of declaration for
7959 temporary, to prevent access before elaboration when the allocator is

7961 (Expand_N_Type_Conversion): On an access type conversion involving an
7962 access parameter, do not apply an accessibility check when the
7963 operand's original node was an attribute other than 'Access. We now
7964 create access conversions for the expansion of 'Unchecked_Access and
7965 'Unrestricted_Access in certain cases and clearly accessibility should
7966 not be checked for those.
7968 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
7969 includes a type conversion of a packed component that has been expanded,
7970 recover the original expression for the object, and use this expression
7971 in the post-call assignment statement, so that the assignment is made
7972 to the object and not to a back-end temporary.
7973 (Freeze_Subprogram): In case of primitives of tagged types not defined
7974 at the library level force generation of code to register the primitive
7975 in the dispatch table. In addition some code reorganization has been

7978 preserve the type of the inherited function after the intrinsic
7979 operation has been expanded.
7981 * exp_ch2.ads, exp_ch2.adb
7982 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
7983 of an entry formal appearing in an assignment statement does not assign
7985 (Expand_Current_Value): Instead of calling a routine to determine
7986 whether the prefix of an attribute reference should be optimized or
7987 not, prevent the optimization of such prefixes all together.
7989 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
7990 component whose prefix is known to be of an access type is an implicit
7991 dereference and does not assign to the prefix.

8003 node, to prevent errors when complex expression is copied.
8004 Fix mishandling of multiple levels of parens

8007 treatment of limited views uniform for all visible declarations in a
8008 limited_withed package.
8009 (New_Copy_Tree): If hash table is being used and itype is visited,
8010 make an entry into table to link associated node and new itype.
8011 (Resolve_Record_Aggregate): Do not add an others box association for a
8012 discriminated record component that has only discriminants, when there
8013 is a box association for the component itself.

8050 Javier Miranda <miranda@adacore.com>
8051 Gary Dismukes <dismukes@adacore.com>
8053 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
8054 to make treatment of limited views uniform for all visible declarations
8055 in a limited_withed package.
8056 Improve warnings for in out parameters

8060 Warn on duplicate pragma Preelaborable_Initialialization
8062 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
8063 generation of a freezing node to ensure proper management of null
8064 excluding access types in the backend.
8065 (Create_Extra_Formals): Test base type of the formal when checking for
8066 the need to add an extra accessibility-level formal. Pass the entity E
8067 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
8068 originally being done in a couple of cases), to ensure that the
8069 Extra_Formals list gets set on the entity E when the first entity is
8071 (Conforming_Types): Add missing calls to Base_Type to the code that
8072 handles anonymous access types. This is required to handle the
8073 general case because Process_Formals builds internal subtype entities
8074 to handle null-excluding access types.
8075 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
8076 functions that need it, even when not marked Requires_Overriding.
8077 Improve warnings for in out parameters
8078 (Analyze_Function_Return): Warn for disallowed null return
8079 Warn on return from procedure with unset out parameter
8080 Ensure consistent use of # in error messages
8081 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
8082 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
8083 the implicit conversion of the expression done for anonymous access
8084 types. This is required to generate the code of the null excluding
8085 check (if required).
8087 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
8088 A formal parameter is never publicly referenceable outside of its body.
8089 (Check_References): For an unreferenced formal parameter in an accept
8090 statement, use the same warning circuitry as for subprogram formal
8092 (Warn_On_Unreferenced_Entity): New subprogram, taken from
8093 Output_Unreferenced_Messages, containing the part of that routine that
8094 is now reused for entry formals as described above.
8095 (Goto_Spec_Entity): New function
8096 (Check_References): Do not give IN OUT warning for dispatching operation
8097 Improve warnings for in out parameters
8098 (Test_Ref): Check that the entity is not undefinite before calling
8099 Scope_Within, in order to avoid infinite loops.
8100 Warn on return from procedure with unset out parameter
8101 Improved warnings for unused variables

8104 Javier Miranda <miranda@adacore.com>
8105 Gary Dismukes <dismukes@adacore.com>
8107 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
8108 (Expand_N_Attribute_Reference): Further unify the handling of the
8109 three forms of access attributes, using common code now for all three
8110 cases. Add a test for the case of applying an access attribute to
8111 an explicit dereference when the context is an access-to-interface
8112 type. In that case we need to apply the conversion to the prefix
8113 of the explicit dereference rather than the prefix of the attribute.
8114 (Attribute_Version, UET_Address): Set entity as internal to ensure
8115 proper dg output of implicit importation.
8116 (Expand_Access_To_Type): Removed.
8117 (Expand_N_Attribute_Reference): Merge the code from the three cases
8118 of access attributes, since the processing is largely identical for
8119 these cases. The substantive fix here is to process the case of a
8120 type name prefix (current instance case) before handling the case
8121 of interface prefixes.
8123 2007-08-14 Thomas Quinot <quinot@adacore.com>
8124 Ed Schonberg <schonberg@adacore.com>
8125 Javier Miranda <miranda@adacore.com>
8126 Robert Dewar <dewar@adacore.com>
8128 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
8129 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
8130 type that is an anonymous access to controlled object, establish
8131 an associated finalization chain to avoid corrupting the global
8132 finalization list when a dynamically allocated object designated
8133 by such a component is deallocated.
8134 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
8135 functions that need it, even when not marked Requires_Overriding.
8136 (Initialize_Tag): Replace call to has_discriminants by call to
8137 Is_Variable_Size_Record in the circuitry that handles the
8138 initialization of secondary tags.

8140 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
8141 Suppress_Initialization pragma for a derived type.
8142 (Is_Variable_Size_Record): New subprogram.
8143 (Build_Offset_To_Top_Functions): New implementation that simplifies the
8144 initial version of this routine and also fixes problems causing
8145 incomplete initialization of the table of interfaces.
8146 (Build_Init_Procedure): Improve the generation of code to initialize the
8147 the tag components of secondary dispatch tables.
8148 (Init_Secondary_Tags): New implementation that simplifies the previous
8149 version of this routine.
8150 (Make_DT): Add parameter to indicate when type has been frozen by an
8151 object declaration, for diagnostic purposes.
8152 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
8153 diagnose attemps to freeze a subprogram when some untagged type of its
8154 profile is a private type whose full view has not been analyzed yet.
8155 (Freeze_Array_Type): Generate init proc for packed array if either
8156 Initialize or Normalize_Scalars is set.
8157 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
8158 constructing the new profile, copy the null_exclusion indicator for each
8159 parameter, to ensure full conformance of the new body with the spec.
8161 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
8162 Create wrappers for constructor functions that need it, even when not
8163 marked Requires_Overriding.
8164 (Covers): Handle properly designated types of anonymous access types,
8165 whose non-limited views are themselves incomplete types.
8166 (Add_Entry): Use an entity to store the abstract operation which hides
8168 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
8169 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
8170 initialization aggregate.
8171 (Function_Interp_May_Be_Hidden): Rename to
8172 Function_Interp_Has_Abstract_Op.
8173 (Has_Compatible_Type): Remove machinery that skips interpretations if
8174 they are labeled as potentially hidden by an abstract operator.
8175 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
8176 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
8177 (Write_Overloads): Output the abstract operator if present.
8178 (Add_Entry): Before inserting a new entry into the interpretation table
8179 for a node, determine whether the entry will be disabled by an abstract
8181 (Binary_Op_Interp_May_Be_Hidden): New routine.
8182 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
8184 (Function_Interp_May_Be_Hidden): New routine.
8185 (Has_Compatible_Type): Do not consider interpretations hidden by
8186 abstract operators when trying to determine whether two types are
8188 (Has_Hidden_Interp): New routine.
8189 (Set_May_Be_Hidden_Interp): New routine.
8190 (Write_Overloads): Write the status of flag May_Be_Hidden.
8192 2007-08-14 Ed Schonberg <schonberg@adacore.com>
8193 Javier Miranda <miranda@adacore.com>
8195 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
8196 types declared in the declarative part of a nested package body or in
8197 the proper body of a stub.

8203 output of implicit importation and exportation.
8204 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
8205 first formal of the thunk is always associated with the controlling
8206 type. In addition perform the following code cleanup: remove formal
8207 Thunk_Alias which is no longer required, cleanup evaluation of the
8208 the controlling type, and update the documentation.
8209 Replace occurrence of Default_Prim_Op_Count by
8210 Max_Predef_Prims. Addition of compile-time check to verify
8211 that the value of Max_Predef_Prims is correct.
8212 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
8213 (Make_DT): Add parameter to indicate when type has been frozen by an
8214 object declaration, for diagnostic purposes.

8216 construction of statically allocated dispatch tables.
8217 (Make_DT): In case of library-level tagged types export the declaration
8218 of the primary tag. Remove generation of tags (now done by Make_Tags).
8219 Additional modifications to handle non-static generation of dispatch
8220 tables. Take care of building tables for asynchronous interface types
8221 (Make_Tags): New subprogram that generates the entities associated with
8222 the primary and secondary tags of Typ and fills the contents of Access_
8223 Disp_Table. In case of library-level tagged types imports the forward
8224 declaration of the primary tag that will be declared later by Make_DT.
8225 (Expand_Interface_Conversion): In case of access types to interfaces
8226 replace an itype declaration by an explicit type declaration to avoid
8227 problems associated with the scope of such itype in transient blocks.
8229 2007-08-14 Robert Dewar <dewar@adacore.com>
8230 Ed Schonberg <schonberg@adacore.com>
8231 Javier Miranda <miranda@adacore.com>
8233 * exp_util.ads, exp_util.adb:
8234 This patch replaces a number of occurrences of explicit tests for N_Null
8235 with calls to Known_Null. This improves tracking of null values, since
8236 Known_Null also catches null constants, and variables currently known to
8237 be null, so we get better tracking.
8238 (Ensure_Defined): create an itype reference only in the scope of the
8240 (Side_Effect_Free): A selected component of an access type that
8241 denotes a component with a rep clause must be treated as not
8242 side-effect free, because if it is part of a linked structure its
8243 value may be affected by a renaming.
8244 (Expand_Subtype_From_Expr): For limited objects initialized with build
8245 in place function calls, do nothing; otherwise we prematurely introduce
8246 an N_Reference node in the expression initializing the object, which
8247 breaks the circuitry that detects and adds the additional arguments to
8248 the called function. Bug found working in the new patch for statically
8249 allocated dispatch tables.
8250 (Is_Library_Level_Tagged_Type): New subprogram.
8251 (Remove_Side_Effects): If the expression of an elementary type is an
8252 operator treat as a function call.
8253 (Make_Literal_Range): If the index type of the array is not integer, use
8254 attributes properly to compute the constraint on the resulting aggregate
8257 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
8258 class-wide type whose base type is an incomplete private type, leave
8259 class-wide type unfrozen so that freeze nodes can be generated
8260 properly at a later point.
8261 (Freeze_Entity, array case): Handle case of pragma Pack and component
8262 size attributre clause for same array.

8911 operations in Derive_Subprograms.
8912 (Collect_Previous_Instances): new procedure within of
8913 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
8914 unit being loaded, to ensure that the generation of global symbols is

8917 takes progenitor types into account.
8918 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
8919 traversing over the primitives of the formal and actual types to locate
8920 any abstract subprograms of the actual type that correspond to a
8921 nonabstract subprogram of the formal type's ancestor type(s), and issue
8922 an error if such is found.
8923 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
8924 Instantiate_Package_Body, Instantiate_Subprogram_Body):
8925 Remove bogus guard around calls to Inherit_Context.

8937 controlling formal is not an in_parameter, reject the actual if it is
8938 an access_to_constant type.
8939 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
8940 type, the candidate operations are found in the scope of declaration of
8941 the type, because the type has no primitive subprograms.
8942 (Analyze_Selected_Component): If prefix is class-wide, and root type is
8943 a private extension, only examine visible components before trying to
8944 analyze as a prefixed call.
8945 Change Entity_List to Type_To_Use, for better readability.
8946 (Has_Fixed_Op): Use base type when checking whether the type of an
8947 operator has a user-defined multiplication/division

8955 formal At_Any_Place indicating, when True, that we want to test for
8956 availability of the stream attribute at any place (as opposed to the
8957 current visibility context only).
8958 (Missing_Read_Write_Attributes): A stream attribute is missing for the
8959 purpose of enforcing E.2.2(8) only if it is not available at any place.
8960 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
8961 when checking the legality of an extension aggregate in a preelaborable
8962 package. Treat the literal null as a valid default expression in a
8963 component declaration for a type with preelaborable initialization.
8964 A limited interface is a legal progenitor for the designated type of a
8965 remote access to class-wide type.

8979 views that are themselves incomplete types.
8980 Handle interfaces visible through limited-with clauses.
8981 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
8982 subprogram generic actual for which we have generated a renaming.

8993 the allocator is not a coextension.
8994 (Resolve): Skip an interpretation hidden by an abstract operator only
8995 when the type of the interpretation matches that of the context.
8996 (Resolve): When looping through all possible interpretations of a node,
8997 do not consider those that are hidden by abstract operators.

10178 Arnaud Charlet <charlet@adacore.com>
10180 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
10181 applicable to types that have the With_Type flag set. Returns the
10182 non-limited view of the type, if available, otherwise the type itself.
10183 For class-wide types, there is no direct link in the tree, so we have
10184 to retrieve the class-wide type of the non-limited view of the Etype.
10185 New attributes Static_Initialization and Static_Elaboration_Desired.

10187 Is_Thread_Body in entities, and all related code.

10200 (Original_Access_Type): Remove, not needed.
10201 (Root_Type): Handle properly subtypes of class-wide-types.
10204 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
10205 class-wide types visible through limited-with clauses.
10206 (Try_Primitive_Operation): When examining all primitive operations of a
10207 tagged type, do not consider subprograms labeled as hidden unless they
10208 belong to a private generic type with a tagged parent.
10209 (Try_Object_Operation): Extensive rewriting, to handle properly various
10210 overloading cases, when several ancestors may have class-wide operations
10211 that are possible candidates, and when the overloaded functions return
10212 array types and have defaulted parameters so that the call may be
10213 interpreted as an indexing.
10214 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
10215 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
10216 successive actuals before analyzing the call itself.
10217 (Try_Primitive_Operation): A primitive operation is compatible with the
10218 prefix if the prefix has a synchronized type and the type of the formal
10219 is its corresponding record, as can be the case when the primitive
10220 operation is declared outside of the body of the type.
10221 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
10222 perform homonym traversal, looking for class-wide operation matches
10223 (formerly done in statements of Try_Class_Wide_Operation). Matches on
10224 access parameters are now restricted to anonymous access types.
10225 (Mark_Allocator): An allocator with a discriminant association parent is
10227 (Try_One_Prefix_Interpretation): If the type of the object is
10228 incomplete, as can be happen when it is a limited view obtained through
10229 a limited_with_clause, the selected component is not part of a prefixed
10231 (Complete_Object_Operation): Diagnose properly an object that is not
10232 aliased when the corresponding controlling formal is an access
10234 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
10235 ambiguous calls in prefixed notation, where two primitives differ only
10236 in that the controlling argument of one is an access parameter.
10238 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
10239 whether a function that returns an unconstrained type can be inlined.
10240 (Process_Formals): Diagnose properly the illegal use of an incomplete
10241 type in the profile of an access_to_subprogram declaration.
10242 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
10243 operations are attached to the corresponding record.
10244 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
10245 When processing a primitive of a concurrent type which implements an
10246 interface change the type of all controlling formals to that of the
10247 corresponding record type.
10248 (Check_Synchronized_Overriding): Relax the conditional logic when trying
10249 to determine the tagged type to which a primitive belongs.
10250 (Check_Conventions): Capture condition to ignore a primitive operation
10251 (which is shared between the loop in Check_Conventions and the one in
10252 Check_Convention) in a new local function Skip_Check.
10253 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
10254 confusion with Check_Conventions' own Prim_Op local variable.
10255 (Create_Extra_Formals): Test for a tagged result type rather than a
10256 controlling result when determining whether to add a BIP_Alloc_Form
10257 formal and a BIP_Final_List formal to the function.
10258 (Check_Conformance); For parameters that are anonymous access types,
10259 subtype conformance requires that the not null and the constant
10260 indicators must match
10261 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
10262 to retrieve the appropriate type when processing a concurrent type
10263 declared within a generic. Minor comment reformatting. Change invocation
10264 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
10266 (Analyze_Subprogram_Body): If the return type of a function is an
10267 anonymous access to the limited view of a class-wide type, and the
10268 non-limited view of the type is available, update the type of the
10269 function so that code can be generated.
10270 (Process_Formals): In case of access-subtype itype whose designated
10271 type is also an itype (situation that happens now with access to
10272 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
10273 attribute to avoid backend problems.
10274 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
10275 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
10276 anonymous types' designated types are same before testing
10277 Subtypes_Statically_Match.
10278 (Create_Extra_Formals): Test for a named access parameter that is a
10279 controlling formal as an additional condition for adding an
10280 accessibility level formal. This can occur in the subp type created for
10281 dispatching calls in Expand_Dispatching_Call, and allows calling
10282 Create_Extra_Formals from that procedure rather than special-casing the
10283 extra formals there.
10284 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
10285 when the function has a controlling result.
10286 (Check_Returns): Add much more knowledge of the optimization of local
10287 raise statements to gotos, to retain proper warnings in this case.
10288 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
10289 nodes when looking for last statement.
10291 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
10292 class-wide types visible through limited with clauses.
10293 (Add_One_Interp): If the operands are anonymous access types, the
10294 predefined operator on universal_access is immediately visibles
10295 (Find_Unique_Type): Handle anonymous access to subprogram types just as
10296 other anonymous access types.
10297 (Disambiguate): Take into account CIL convention.
10298 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.

10319 in extension aggregates.
10320 (Flatten): Other conditions being met, an aggregate is static if the
10321 low bound given by component associations is different from the low
10322 bound of the base index type.
10323 (Packed_Array_Aggregate_Handled): If the component type is itself a
10324 packed array or record, the front-end must expand into assignments.
10325 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
10326 Init_Pr, instead of Ancestor_Is_Expression.
10327 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
10328 coextension chain root, either generate a list controller or use the
10329 already existing one.
10330 (Static_Array_Aggregate): New procedure to construct a positional
10331 aggregate that can be handled by the backend, when all bounds and
10332 components are compile-time known constants.
10333 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
10334 types covering interface types into assignments.
10335 (Replace_Type): move to Build_Record_Aggr_Code.
10336 (Expand_Record_Aggr_Code): if the target of the aggregate is an
10337 interface type, convert to the definite type of the aggregate itself,
10338 so that needed components are visible.
10339 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
10340 components and the context is an extended return statement do not
10341 create a transient block for it, to prevent premature finalization
10342 before the return is executed.
10343 (Gen_Assign): Do not generate a call to deep adjust routine if the
10344 component type is itself an array of controlled (sub)-components
10345 initialized with an inner aggregate.
10346 (Component_Check): New name for Static_Check. This name is now more
10347 appropriate, and documentation is added which was missing.
10348 (Component_Check): Add test for bit aligned component value
10349 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
10350 Tagged_Comps, name is more appropriate given added function below.
10351 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

10357 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
10358 Terminated: Add unchecked type conversion from System.Address to
10359 System.Tasking.Task_Id when calling the predefined primitive
10361 Disable new Ada 05 accessibility check for JVM.NET targets, which
10362 cannot be implemented in a practical way.
10363 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
10364 the sources always references the tag of the actual object. Therefore,
10365 if 'Tag is applied in the sources to class-wide interface objects we
10366 generate code that displaces "this" to reference the base of the object.
10367 (Expand_N_Attribute_Reference, case Size): Return specified size if
10368 known to front end.
10369 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
10370 has code that displaces the pointer of the object to manage interface
10371 types. However this code must not be executed when the prefix is a
10372 subprogram. This bug caused the wrong expansion of the internally
10373 generated assignment that fills the dispatch table when the primitive
10374 is a function returning a class-wide interface type.
10375 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
10376 Set_Attribute_Name for Name_Unaligned_Valid.

10379 Gary Dismukes <dismukes@adacore.com>
10381 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
10382 If the initialization is the equivalent aggregate of the initialization
10383 procedure of the type, do not remove it.
10384 (Expand_N_Attribute_Definition_Clause): Exclude access variables
10385 initialized to null from having their expression reset to empty and
10386 note this exception in the comment.

10394 Add "with" and "use" clauses for Sem_Attr.
10395 (Expand_Current_Value): Do not replace occurences of attribute
10396 references where the prefix must be a simple name.
10398 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
10399 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
10400 Attribute_Requires_Simple_Name_Prefix.
10401 (Name_Modifies_Prefix): Body of new function.
10402 (Requires_Simple_Name_Prefix): Body of new function.
10403 (Resolve_Attribute, case Access): Improve error message for case of
10404 mismatched conventions.
10405 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
10407 (Analyze_Attribute, case 'Access): If the type of the prefix is a
10408 constrained subtype for a nominal unconstrained type, use its base type
10409 to check for conformance with the context.
10410 (Resolve_Attribute): Remove test of the access type being associated
10411 with a return statement from condition for performing accessibility
10412 checks on access attributes, since this case is now captured by
10413 Is_Local_Anonymous_Access.
10414 (Analyze_Access_Attribute): Set Address_Taken on entity
10415 (Analyze_Attribute, case Address): Set Address_Taken on entity
10416 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
10417 validating an access attribute whose prefix is a current instance.
10418 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
10419 applied to dispatching operations, if freezing is required then we set
10420 the attribute Has_Delayed_Freeze in the prefix's entity.
10421 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
10422 current scope if access of local subprogram taken
10423 (Analyze_Access_Attribute): Check legality of self-reference even if the
10424 expression comes from source, as when a single component association in
10425 an aggregate has a box association.
10426 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
10427 the prefix if it is a protected operation and the attribute is
10428 Unrestricted_Access.
10429 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
10430 reference to the base type of the context, to force a constraint check
10431 when the context is an access subtype with an explicit constraint.
10432 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
10433 node is rewritten as an interface conversion. leave unanalyzed after
10434 resolution, to ensure that type checking against the context will take

10438 Javier Miranda <miranda@adacore.com>
10439 Robert Dewar <dewar@adacore.com>
10441 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
10442 wrapper when the full view of the controlling type of an inherited
10443 function that dispatches on result implements interfaces.
10444 (Expand_N_Object_Declaration): In cases where the type of the
10445 declaration is anonymous access, create finalization list for it.
10446 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
10447 if the object has no explicit initialization, to match description of
10448 functionality of pragam Persistent_BSS.
10449 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
10450 new function to build static aggregates, to replace initialization call
10451 when static initialization is desired.
10452 (Freeze_Type): Generate a list controller for an access type whenever
10453 its designated type has controlled anonymous access discriminants.
10454 (Build_Equivalent_Aggregate): New procedure to compute a static
10455 aggregate to be used as default initialization for composite types,
10456 instead of a generating a call to the initialization procedure for the
10458 (Build_Initialization_Call): When available, replace a call to the
10459 initialization procedure with a copy of the equivalent static aggregate
10461 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
10462 declarations for objects of a class-wide interface type, rather than
10463 just identifiers, to prevent visibility problems.
10464 (Expand_N_Object_Declaration): When expanding the declaration for an
10465 object of a class-wide interface type, preserve the homonym chain of
10466 the original entity before exchanging it with that of the generated
10467 renaming declaration.
10468 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
10469 active, because there is no way to handle the exception.
10470 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
10471 to do a minimum decoration of the Access_Disp_Table list.
10472 (Expand_Record_Controller): Avoid the addition of the controller between
10473 the component containing the tag of a secondary dispatch table and its
10474 adjacent component that stores the offset to the base of the object.
10475 This latter component is only generated when the parent type has
10476 discriminants ---documented in Add_Interface_Tag_Components).
10477 (Apply_Array_Size_Check): Removed, no longer needed.
10478 (Expand_N_Full_Type_Declaration): If the type has anonymous access
10479 components, create a Master_Entity for it only if it contains tasks.
10480 (Build_Init_Procedure): Suppress the tag assignment compiling under
10482 (Freeze_Record_Type): Remove code associated with creation of dispatch
10484 (Init_Secondary_Tags): Update type of actuals when generating calls to
10485 Ada.Tags.Set_Offset_To_Top
10486 (Stream_Operation_OK): Disable use of streams compiling under no
10488 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
10489 if Has_Init_Expression set.
10490 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
10491 Register_Primitive, which provides the same functionality.
10492 (Requires_Init_Proc): Return false in case of interface types.
10493 (Add_Secondary_Tables): Use the new attribute Related_Interface to
10495 (Predefined_Primitive_Freeze): Do not assume that an internal entity
10496 is always associated with a predefined primitive because the internal
10497 entities associated with interface types are not predefined primitives.
10498 Therefore, the call to Is_Internal is replaced by a call to the
10499 function Is_Predefined_Dispatching_Operation.
10500 (Make_Eq_If): When generating the list of comparisons for the
10501 components of a given variant, omit the controller component that is
10502 present if the variant has controlled components.

10505 Hristian Kirtchev <kirtchev@adacore.com>
10506 Bob Duff <duff@adacore.com>
10508 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
10509 handle the creation of finalization lists and calls for nested
10510 coextensions when the root of the chains is part of a return statement.
10511 (Inside_A_Return_Statement): New function inside Complete_Coextension_
10513 (Expand_Record_Equality): Skip components that are interface types.
10514 (Displace_Allocator_Pointer): Add missing support for interface subtypes
10515 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
10516 with Rewrite_Coextension. Change the condition for detecting coextension
10518 (Is_Local_Access_Discriminant): Removed.
10519 (Rewrite_Coextension): New routine which rewrites a static coextension
10520 as a temporary and uses its unrestricted access in the construction of
10522 (Complete_Coextension_Finalization): New routine. Generate finalization
10523 attachment calls to all delayed coextensions.
10524 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
10525 the allocator is not a coextension itself and has delayed coextensions.
10526 If the current allocator is controlled, but also a coextension, delay
10527 the generation of the finalization attachment call.
10528 Rename local variable "Node" to "Nod" in order to avoid confusion with
10530 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
10531 limited types that are not inherently limited. Such an allocator is
10532 illegal, but is generated by the expander for a return statement, to
10533 copy the result onto the secondary stack. This is the only case where a
10534 limited object can be copied. Generate code to displace the pointer
10535 to the object if the qualified expression is a class-wide interface
10536 object. Such displacement was missing and hence the copy of the object
10538 (Apply_Accessibility_Check): Handle allocated objects initialized in
10540 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
10541 and Expand_Allocator_Expression. Allocating class-wide interface objects
10542 this routine displaces the pointer to the allocated object to reference
10543 the component referencing the corresponding secondary dispatch table.
10544 Expand_Allocator_Expression): Add missing support to allocate class-wide
10545 interface objects initialized with a qualified expression.
10546 (Get_Allocator_Final_List): Test for an anonymous access type that is a
10547 function result type, and use the finalization list associated with the
10548 function scope in that case (such an anonymous type should not be
10549 treated like an access parameter's type).

10552 Gary Dismukes <dismukes@adacore.com>
10553 Javier Miranda <miranda@adacore.com>
10555 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
10556 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
10557 required exception handler.
10558 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
10559 properly the case of a function whose return type is a limited
10560 class-wide interface type. Modify the code of the accessibility
10561 check to handle class-wide interface objects. In this case we need to
10562 displace "this" to reference the primary dispatch table to get access
10563 to the TSD of the object (to evaluate its accessibility level).
10564 (Expand_N_Extended_Return_Statement): Test for a tagged result type
10565 rather than a controlling result as one of the conditions for
10566 generating tests of the implicit BIP_Alloc_Form formal. The
10567 initialization assignment is also handled according to whether the
10568 result is tagged instead of controlling.
10569 In the case where the init assignment is inserted in the "then" part of
10570 the allocation conditional, rewrite the target to be a dereference of
10571 the implicit BIP_Object_Access formal.
10572 If the returned value is unconstrained and created on the secondary
10573 stack, mark the enclosing block and function so that the secondary
10574 stack is not reclaimed on return.
10575 Treat returns from functions with controlling results similarly to
10576 returns from functions with unconstrained result subtypes.
10577 If the object returned is unconstrained, and an allocator must be
10578 created for it, analyze the allocator once the block for the extended
10579 return is installed, to ensure that finalizable components
10580 of the expression use the proper finalization list. Guard the call to
10581 Move_Final_List with a check that there is something to finalize.
10582 (Make_Tag_Ctrl_Assignment): Use "old" handling
10583 of controlled type assignment for virtual machines, since new code uses
10584 unsupported features (such as direct access to bytes in memory).

10587 Ed Schonberg <schonberg@adacore.com>
10589 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
10590 accessibility actual, check for the case of an aliased object that has
10591 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
10592 we fall into processing for the attribute rather than the name of the
10594 (Expand_Inline_Call): If an actual is a literal, and the corresponding
10595 formal has its address taken in the body, create a temporary to capture
10596 value. If the return type is a limited interface, do not treat the
10597 return value as Controlled.
10598 (Is_In_Place_Function): If the return type is a limited interface,
10599 treat as returning in place. The actual returned object may not always
10600 be limited, but the caller has to assume that it is returned in place.
10601 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
10602 context of an allocator, use the correct finalization chain (that is,
10603 the chain belonging to the access type, rather than the chain belonging
10604 to the current scope).
10605 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
10606 result type rather than a controlling result as a precondition for
10607 adding an allocation form actual to a build-in-place call.
10608 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
10609 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
10610 primitive in the dispatch tables. This work is now done by Make_DT when
10611 the type is frozen.
10612 (Register_Predefined_DT_Entry): Removed.
10613 (Add_Return): If end label is not present, use sloc of last statement
10614 for generated return statement in procedure, for better gdb behavior
10616 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
10617 object address nodes to ensure proper processing by routines like
10619 (Expand_Call): Fix generation of validity check for parameter
10620 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
10621 the allocation form parameter if the result subtype is constrained,
10622 except when the function has a controlling result.
10623 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
10624 rather than Is_Controlled and Has_Controlled_Component, since we want to
10625 include class-wide result types in this treatment. Also test for a
10626 controlling result, since that also requires passing a finalization
10628 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
10629 even when the result subtype is constrained, to handle calls involving
10630 controlling results.
10631 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
10632 is now called even when the result subtype is constrained, to handle
10633 calls involving controlling results.
10634 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
10635 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
10636 now performs the test).
10637 (Make_Build_In_Place_Call_In_Object_Declaration):
10638 Add_Alloc_Form_Actual_* is now called even when the result subtype is
10639 constrained, to handle calls involving controlling results.
10640 (Add_Return): Accomodate rewritten pattern from local raise to goto
10641 transformation, so that we still recognize an transfer statement
10642 and do the right thing here in that case.
10643 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
10644 and end of subprogram code.
10645 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
10646 support for primitives that are functions (without formals) with a
10647 controlling result.
10648 (Inherited_From_Formal): If the actual subtype has not generic parent
10649 type, it is not an actual for a formal derived type, and there is no
10650 operation to inherit from the formal.

10653 Thomas Quinot <quinot@adacore.com>
10655 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
10656 inserted cleanup code appropriately for GDB use.
10657 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
10658 exception handler for Deep_Adjust or Deep_Finalize.
10659 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
10660 Raise_From_Controlled_Operation is available, use a call to that
10661 subprogram instead of a plain "raise Program_Error" node to raise
10662 Program_Error if an exception is propagated from an Adjust or Finalize
10664 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
10665 appears in the optional statement list of a triggering alternative, the
10666 scope actions can be inserted directly there, and not in the list that
10667 includes the asynchronous select itself.

10671 Hristian Kirtchev <kirtchev@adacore.com>
10673 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
10674 generated exception handler appropriately when debugging generated code.
10675 Deal properly with No_Exception_Propagation restriction mode.
10676 (Expand_N_Abort_Statement): Add an unchecked type conversion from
10677 System.Address to System.Tasking.Task_Id when processing the result of
10678 the predefined primitive _disp_get_task_id.
10679 (Expand_N_Asynchronous_Select): Clarify comment.
10680 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
10681 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
10682 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
10683 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
10684 privals and for generated call to Complete_Entry_Body, for better gdb
10686 (Copy_Result_Type): Utility to construct a parameter and result profile
10687 for protected functions whose return type is an anonymous access to
10689 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
10691 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
10692 point when the local-raise-to-goto transformation has taken place.
10694 2007-06-06 Javier Miranda <miranda@adacore.com>
10695 Nicolas Setton <setton@adacore.com>
10697 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
10698 functionality when the backend is generating code.
10699 Otherwise any serious error
10700 reported by the backend calling the frontend routine Error_Msg
10701 changes the Compilation_Mode to Check_Semantics, disables the
10702 functionality of this routine and causes the generation of
10703 spureous additional errors.
10705 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
10706 debugging information now generated by the compiler for fat-pointer
10708 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
10710 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
10712 2007-06-06 Thomas Quinot <quinot@adacore.com>
10714 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
10715 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
10716 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
10717 For a remote call to a function with a classwide return type, apply an
10718 E.4(18) check to the returned value.
10719 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
10720 stream attributes of the designated type of an RACW, as they are not
10721 dispatching primitive operations.
10723 2007-06-06 Geert Bosch <bosch@adacore.com>
10725 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
10727 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
10729 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
10730 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
10732 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
10734 2007-06-06 Javier Miranda <miranda@adacore.com>
10736 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
10737 attribute compiling package Ada.Tags under No_Run_Time_Mode.
10739 2007-06-06 Javier Miranda <miranda@adacore.com>
10741 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
10742 deallocation of class-wide interface objects.
10743 (Expand_Dispatching_Constructor_Call): Take into account that if the
10744 result of the dispatching constructor is an interface type, the
10745 function returns a class-wide interface type; otherwise the returned
10746 object would be actual. The frontend previously accepted returning
10747 interface types because Expand_Interface_Actuals silently performed
10748 the management of the returned type "as if" it were a class-wide
10750 (Expand_Dispatching_Constructor_Call): Replace call to
10751 Make_DT_Access_Action by direct call to Make_Function_Call.

10754 Ed Schonberg <schonberg@adacore.com>
10756 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to

12576 (E_Return_Statement): This node type has the Finalization_Chain_Entity
12577 attribute, in case the result type has controlled parts.
12578 (Requires_Overriding): Add this new flag, because "requires
12579 overriding" is subtly different from "is abstract" (see AI-228).
12580 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
12581 Is_Abstract_Type. Make sure these are called only when appropriate.

12643 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
12644 "abstract subprograms must be visible" message, whether or not the type
12645 is an interface; that is, remove the special case for interface types.

12671 build-in-place functions with result type with controlled parts.
12672 Remove no longer used entities.
12674 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
12675 longer needed, because the full type is now limited, and therefore a
12676 pass-by-reference type.
12677 (Foreign_Task_Level): New constant.
12679 * s-tassta.ads, s-tassta.adb (Move_Activation_Chain): New procedure to

12722 attempt to derive from a synchronized tagged type.
12723 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
12724 type, inherit the class-wide type already created, because it may
12725 already have been used in a self-referential anonymous access component.

12727 that use (a subtype of) the class-wide type of the enclosing type.
12728 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
12729 Derived_Type for Prev formal on call to
12730 Check_Anonymous_Access_Components rather than Empty.
12731 (Make_Incomplete_Type_Declaration): Add test for case where the type has

12780 (Compile): When compiling a predefined source, add -gnatpg
12781 as the second switch, after -c.
12782 (Compile_Sources): Allow compilation of Annex J renames without -a

12813 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
12814 when -gnatg is not specified.
12815 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
12816 there is no need to generate always a record_definition_node in case
12817 of synchronized interface types.

12844 (Convert_Aggr_In_Allocator): If the allocator is for an access
12845 discriminant and the type is controlled. do not place on a finalization
12846 list at this point. The proper list will be determined from the

12866 parameter of the containing subprogram.
12867 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
12868 under No_Dispatching_Calls restriction. During the semantic analysis
12869 we already notified such violation.

12888 Modify the declaration of the object containing the TSD
12889 because we now expand code that has a higher level of abstraction.
12890 The TSD has a discriminant containing the Inheritance Depth Level,
12891 value that is used in the membership test but also to fix the size
12892 of the table of ancestors.
12893 (Expand_Interface_Conversion): Insert function body at the closest place
12894 to the conversion expression, to prevent access-before-elaboration

12951 support concurrent types implementing interfaces.
12952 (Find_Implemented_Interface): Removed. All the calls to this subprogram

12956 CW_Or_Controlled_Type whenever the issue is related to
12957 using or not the secondary stack.

12997 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
12998 a protected version of an operation declared in the private part of
12999 a protected object, because they may be invoked through a callback.
13000 (Set_Privals): If the type of a private component is an anonymous access
13001 type, do not create a new itype for each protected body.
13002 If the body of a protected operation creates
13003 controlled types (including allocators for class-widetypes), the
13004 body of the corresponding protected subprogram must include a
13006 (Build_Activation_Chain_Entity): Build the chain entity for extended
13008 (Type_Conformant_Parameters): Use common predicate Conforming_Types
13009 to determine whether operation overrides an inherited primitive.

13011 for a possible overriding candidate.
13012 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
13013 hold an actual parameter value since its initialization is separated
13014 from the the declaration. Prevents errors on null-excluding access

13018 Pablo Oliveira <oliveira@adacore.com>
13020 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
13021 Do an Unchecked_Conversion to handle the passage from the Underlying
13022 Type to the Base Type when calling Build_To_Any_Call and
13023 Build_From_Any_Call.
13024 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
13025 E_Constant, depending upon Variable formal.
13026 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13027 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
13028 parameter that requires an extra constrained parameter, declare
13029 temporary for actual as a variable, not a constant.
13030 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
13031 the unit being compiled is the one that contains the stub type.
13032 Change primitive operation name for the RACW associated with a RAS
13033 from Call to _Call so it cannot clash with any legal identifier.
13034 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
13036 (Append_RACW_Bodies): New subprogram.
13037 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
13038 Add_Receiving_Stubs_To_Declarations functions.
13039 When expanding a package body, this list correspond to the
13040 statements in the HSS at the end of the pacakge.
13041 When expanding a package spec, this list correspond to the

13044 registering the receiving stubs at the end of the 'Stmts' list.
13045 (RCI_Package_Locator): Pass the new Version generic formal when
13046 instantiating a RCI_Locator package.
13047 (Build_From_Any_Function): To compute the High bound for an
13048 unconstrained array actual, we add the Low bound with the length.
13049 Thus we must convert the low bound and the length to an appropriate
13050 type before doing the sum.
13051 (Build_Subprogram_Receiving_Stubs, PolyORB):
13052 * Retrieve the extra formals parameters at the
13053 end of the parameter stream.
13054 * Use Move_Any_Value to write back out parameters
13055 after executing the request as it is more efficient
13056 than Copy_Any_Value.
13057 * Build the any containing Extra Formals with the
13058 appropriate typecode.
13059 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
13060 empty Component_List.
13061 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
13062 the tree the declaration for an object that serves as actual parameter
13063 in server-side stubs.
13064 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13065 PolyORB_Support.Build_Subprogram_Receiving_Stubs):

13068 Extra Constrained Parameters.
13069 (Build_General_Calling_Stubs): Set the parameter type to boolean for

13073 function with the first not implicit parent type.
13074 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
13075 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
13076 typecode from the Etype. Therefore we retrieve the correct typecode
13077 with a call to Get_Any_Type.
13078 (Copy_Specification): Do controlling formal type substitution based on
13079 Is_Controlling_Formal flag, instead of caller-provided object type.
13080 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
13081 a RACW primitive operation, we might get a subprogram declaration for an
13082 ancestor of the RACW designated type (not for the designated type
13083 itself), in the case where this operation is inherited. In this case we
13084 have no easy means of determining the original tagged type for which
13085 the primitive was declared, so instead we now rely on
13086 Copy_Specification to use the Is_Controlling_Formal flag to determine
13087 which formals require type substitution.

13095 handler unsuitable as a target for a local raise statement.
13096 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
13097 run-time subprogram CW_Membership by call to Build_CW_Membership.
13098 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
13099 by a function call, a temporary must be created before expanding the
13100 Constructor_Call itself, to prevent out-of-order elaboration in the
13101 back-end when stack checking is enabled..
13103 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13105 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
13106 result are the bounds of the left operand, not the right.
13108 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13111 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

13232 This is needed as it is necessary to have access to both versions in the
13233 runtime for the form parameter encoding support.
13234 This set of patch add support for the encoding form parameter.
13235 (S2WS): Improve implementation to handle cases where the filename is not
13236 UTF-8 encoded. In this case we default to using the current code page
13237 for the conversion.

13285 __gnat_adjust_context_for_raise.
13286 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
13287 implementation of floating point operations as native x86 targets.
13288 So the FPU should be initialized in the same way using finit. Fix
13289 floating point operations accuracy issues.
13290 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
13291 member in struct sigaction, so as to avoid warning for incompatible

13461 to Executable_Prefix_Path.
13462 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
13465 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
13466 canonical directory name to open the directory from which files are
13468 (Record_Other_Sources): Idem.
13469 (Locate_Directory): Add the possibility to create automatically missing
13470 directories when Setup_Projects is True.
13471 Call Locate_Directory so that the directory will be created when
13472 Setup_Projects is True, for object dir, library dir, library ALI dir,
13473 library source copy dir and exec dir.
13475 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
13478 2007-04-06 Robert Dewar <dewar@adacore.com>
13480 * sem_ch13.ads, sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
13481 Use First/Next_Component_Or_Discriminant
13482 (Analyze_Record_Representation_Clause):

13484 (Check_Component_Overlap): Use First/Next_Component_Or_Discriminant
13485 (Analyze_Attribute_Definition_Clause, case Value_Size): Reject
13486 definition if type is unconstrained.
13487 (Adjust_Record_For_Reverse_Bit_Order): New procedure
13488 (Analyze_Attribute_Definition_Clause): Split Is_Abstract flag into
13489 Is_Abstract_Subprogram and Is_Abstract_Type.
13490 (Adjust_Record_For_Reverse_Bit_Order): New procedure
13492 * repinfo.adb (List_Record_Info): Use First/
13493 Next_Component_Or_Discriminant.
13495 * style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
13498 * stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch
13499 Include -gnatyA in default switches
13501 * opt.ads: (Warn_On_Non_Local_Exception): New flag
13502 (Warn_On_Reverse_Bit_Order): New flag
13503 (Extensions_Allowed): Update the documentation.
13504 (Warn_On_Questionable_Missing_Parens): Now on by default
13506 * usage.adb: Add documentation of -gnatw.x/X switches
13507 Document new -gnatyA style switch
13508 -gnatq warnings are on by default
13510 2007-04-06 Ed Falis <falis@adacore.com>
13512 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
13513 full word is no longer compared twice.
13515 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13517 * sem_ch10.adb (Install_Limited_Context_Clauses.
13518 Expand_Limited_With_Clause): Use a new copy of selector name in the
13519 call to Make_With_Clause. This fixes the tree structure for ASIS
13520 purposes. Nothing is changed in the compiler behaviour.
13521 (Process_Body_Clauses): Handle properly use clauses whose prefix is
13522 a package renaming.
13523 (Install_Limited_With_Clauses): Do not install non-limited view when it
13524 is still incomplete.
13526 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13527 Gary Dismukes <dismukes@adacore.com>
13529 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
13530 when capturing size information, instead of base type, which for a
13531 formal array type will be the unconstrained type.
13532 (Analyze_Formal_Object_Declaration): Add check for illegal default
13533 expressions for a formal in object of a limited type.
13534 (Instantiate_Object): Ditto.
13535 (Check_Formal_Package_Instance): Skip entities that are formal objects,
13536 because they were defaulted in the formal package and no check applies
13538 (Check_Formal_Package_Instance): Extend conformance check to other
13539 discrete types beyond Integer.
13540 (Process_Default): Copy directly the unmatched formal. A generic copy
13541 has already been performed in Analyze_Formal_Package.
13542 (Analyze_Associations): If a formal subprogram has no match, check for
13543 partial parametrization before looking for a default, to prevent
13545 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
13546 not set the instantiation environment before analyzing the actuals.
13547 Fixes regression on 8515-003 with implementation of AI-133.
13548 Set_Instance_Env checks whether the generic unit is a predefined
13549 unit, in which case the instance must be analyzed with the latest Ada
13550 mode. This setting must take place after analysis of the actuals,
13551 because the actuals must be analyzed and frozen in the Ada mode extant
13552 outside of the current instantiation.
13553 (Save_Env, Restore_Env): Preserve and restore the configuration
13554 parameters so that predefined units can be compiled in the proper Ada
13556 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
13557 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
13558 and Is_Abstract_Type.
13559 (Analyze_Formal_Package): For better error recovery, Add exception
13560 handler to catch Instantion_Error, which can be raised in
13561 Analyze_Associations
13563 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13564 Bob Duff <duff@adacore.com>
13565 Gary Dismukes <dismukes@adacore.com>
13567 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
13568 prefix type is a discriminated subtype of the type of the formal.
13569 (Analyze_Allocator): Collect all coextensions regardless of the context.
13570 Whether they can be allocated statically is determined in exp_ch4.
13571 (Analyze_Selected_Component): If the prefix is a limited view and the
13572 non-limited view is available, use the non-limited one.
13573 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
13574 therefore illegal), suggest a qualified expression rather than a type
13575 conversion, because a type conversion would be illegal in this context.
13576 (Anayze_Allocator): Trace recursively all nested allocators so that all
13577 coextensions are on the corresponding list for the root. Do no mark
13578 coextensions if the root allocator is within a declaration for a stack-
13579 allocated object, because the access discriminants will be allocated on
13581 (Analyze_Call): Remove restriction on calls to limited functions for the
13582 cases of generic actuals for formal objects, defaults for formal objects
13583 and defaults for record components.
13584 (Analyze_Allocator): Before analysis, chain coextensions on the proper
13585 element list. Their expansion is delayed until the enclosing allocator
13586 is processed and its finalization list constructed.
13587 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
13588 for an operation with the given name among the primitive operations of
13589 the corresponding record type.
13590 (Analyze_Selected_Component): If the prefix is a task type that
13591 implements an interface, and there is no entry with the given name,
13592 check whether there is another primitive operation (e.g. a function)
13594 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
13595 properly the indexing of a function call written in prefix form, where
13596 the function returns an array type, and all parameters of the function
13597 except the first have defaults.
13598 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
13599 the original operands, rather than relocating them, for efficiency and
13600 to work properly when an operand is overloaded.
13601 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
13602 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
13603 (Analyze_Selected_Component): If the prefix is a private extension, only
13604 scan the visible components, not those of the full view.
13605 (Try_Primitive_Operation): If the operation is a procedure, collect all
13606 possible interpretations, as for a function, because in the presence of
13607 classwide parameters several primitive operations of the type can match
13608 the given arguments.
13610 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13611 Robert Dewar <dewar@adacore.com>
13613 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
13614 tag-indeterminate call to an abstract function, when the left-hand side
13616 (Analyze_Loop_Statement): Improve detection of infinite loops
13618 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13619 Thomas Quinot <quinot@adacore.com>
13621 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
13622 out of Analyze_Package_Declaration, because processing must be applied
13623 to package bodies as well, for deferred constants completed by pragmas.
13624 (Analyze_Package_Declaration): When the package declaration being
13625 analyzed does not require an explicit body, call Check_Completion.
13626 (May_Need_Implicit_Body): An implicit body is required when a package
13627 spec contains the declaration of a remote access-to-classwide type.
13628 (Analyze_Package_Body): If the package contains RACWs, append the
13629 pending subprogram bodies generated by exp_dist at the end of the body.
13630 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
13631 Is_Abstract_Subprogram and Is_Abstract_Type.
13632 (Preserve_Full_Attributes): The full entity list is not an attribute
13633 that must be preserved from full to partial view.
13635 * sem_dist.adb (Add_RAS_Dereference_TSS):
13636 Change primitive name to _Call so it cannot clash with any legal
13637 identifier, and be special-cased in Check_Completion.
13638 Mark the full view of the designated type for the RACW associated with
13639 a RAS as Comes_From_Source to get proper view switching when installing
13640 private declarations.
13641 Provite a placeholder nested package body along with the nested spec
13642 to have a place for Append_RACW_Bodies to generate the calling stubs
13643 and stream attributes.
13645 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13646 Robert Dewar <dewar@adacore.com>
13648 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
13649 that is a limited view, check the non-limited view if available.
13650 (Undefined): Refine error message for missing with of Text_IO
13651 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
13652 to distinguish real missing with cases.
13653 Fix format of all missing with messages
13654 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
13655 renaming as body when renamed entity is abstract.
13657 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13658 Javier Miranda <miranda@adacore.com>
13660 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make

13670 Javier Miranda <miranda@adacore.com>
13672 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
13673 dereference of a local object R created as a reference to another
13674 object O, use the access level of O.
13675 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
13676 rather than local Same_Formal_Type, to check whether protected operation
13677 overrides an inherited one.
13678 (Same_Formal_Type): New predicate, used when matching signatures of
13679 overriding synchronized operations, to handle the case when a formal
13680 has a type that is a generic actual.
13681 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
13682 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
13683 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
13684 syntactic ambiguities involving indexing of function calls that return
13686 (Abstract_Interface_List): New subprogram that returns the list of
13687 abstract interfaces associated with a concurrent type or a
13688 concurrent record type.
13689 (Interface_Present_In_Parent): New subprogram used to check if a
13690 given type or some of its parents implement a given interface.
13691 (Collect_Abstract_Interfaces): Add support for concurrent types
13692 with interface types.
13693 (Has_Abstract_Interfaces): Add support for concurrent types with
13695 (Is_Parent): New subprogram that determines whether E1 is a parent
13696 of E2. For a concurrent type its parent is the first element of its
13697 list of interface types; for other types this function provides the
13698 same result than Is_Ancestor.
13699 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
13700 (Collect_Synchronized_Interfaces): Removed because the subprogram
13701 Collect_Abstract_Interfaces provides this functionality.
13702 (Collect_Abstract_Interfaces): Minor update to give support to
13703 concurrent types and thus avoid undesired code duplication.
13704 (Get_Subprogram_Entity): Handle entry calls.
13705 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
13707 (Enter_Name): Do not give -gnatwh hiding warning for record component

13721 correspond to access discriminants of dynamically allocated objects.
13722 (N_Block_Statement): Document the fact that the corresponding entity
13723 can be an E_Return_Statement.
13724 (Is_Coextension): New flag for allocators.

13743 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
13744 expression with a COMPOUND_EXPR including the call instead of emitting
13745 the call directly here.
13746 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
13747 high bound is constant and the slice is empty. Tidy.
13748 (tree_transform, case N_Op_Not): Handle properly the case where the
13749 operation applies to a private type whose full view is a modular type.
13750 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
13751 Address_Clause, use the associated Expression as the GNAT tree
13752 representing the choice value to ensure the corresponding GCC tree is
13753 of the proper kind.
13754 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
13755 instead of just the operands, as the base GCC stabilize_reference does.
13756 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
13757 requested; otherwise fail.
13758 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

13763 implementation of UI_Div.
13764 (UI_Div): Reimplement as a call to UI_Div_Rem.
13765 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
13766 remainder, avoiding the cost of a multiplication and a subtraction.
13767 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
13768 provides both quotient and remainder in a single computation.
13769 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
13770 functions for uint.
13771 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
13772 is undefined if the given n is not inversible.
13774 2007-04-06 Olivier Hainque <hainque@adacore.com>

14018 (mainly static expression evaluation).
14019 Reword some continuation messages
14020 Add some \\ sequences to continuation messages
14021 (Resolve_Call): Refine infinite recursion case. The test has been

14035 during analysis, and use May_Be_Lvalue to distinguish read/write.
14036 (Valid_Array_Conversion): New procedure, abstracted from
14037 Valid_Conversion, to incorporate accessibility checks for arrays of
14038 anonymous access types.
14039 (Valid_Conversion): For a conversion to a numeric type occurring in an
14040 instance or inlined body, no need to check that the operand type is
14041 numeric, since this has been checked during analysis of the template.

14324 alignment of a field in a variant record might not be accurate. Add a
14325 safety test to make sure no alignment is set to a smaller value than
14326 the alignment of the field type.

14798 an aliased prefix must be known to be constrained in order to use True
14799 for the attribute value, and now it's possible for some aliased views
14800 to be unconstrained.
14802 2006-10-31 Robert Dewar <dewar@adacore.com>
14804 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
14805 (Expand_Entity_Reference): Correct error of not handling subprogram
14806 formals in current_value processing.
14808 2006-10-31 Javier Miranda <miranda@adacore.com>
14809 Robert Dewar <dewar@adacore.com>
14810 Ed Schonberg <schonberg@adacore.com>
14811 Gary Dismukes <dismukes@adacore.com>
14813 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
14814 register in the final list objects containing class-wide interfaces;
14815 otherwise we incorrectly register the tag of the interface in the final
14817 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
14818 generate the wrapper if the parent primitive is abstract. This is
14819 required to report the correct error message.
14820 (Expand_N_Subtype_Indication): Do validity checks on range
14821 (Clean_Task_Names): If an initialization procedure includes a call to
14822 initialize a task (sub)component, indicate that the procedure will use
14823 the secondary stack.
14824 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
14825 compatibility for interfacing with CPP by default.
14826 (Expand_N_Object_Declaration): Only build an Adjust call when the
14827 object's type is a nonlimited controlled type.
14828 * exp_ch3.adb: Add with and use of Exp_Ch6.
14829 (Expand_N_Object_Declaration): Check for object initialization that is a
14830 call to build-in-place function and apply Make_Build_In_Place_Call_In_
14831 Object_Declaration to the call.
14832 (Freeze_Type): When the designated type of an RACW was not frozen at the
14833 point where the RACW was declared, validate the primitive operations
14834 with respect to E.2.2(14) when it finally is frozen.
14835 (Build_Initialization_Call,Expand_Record_Controller): Rename
14836 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
14837 return-by-reference has no meaning in Ada 2005.
14838 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
14839 to register tag of the immediate ancestor interfaces in the
14840 run-time structure.
14841 (Init_Secondary_Tags): Moved to the specification to allow the
14842 initialization of extension aggregates with abstract interfaces.
14843 (Build_Master_Renaming): Make public, for use by function declarations
14844 whose return type is an anonymous access type.
14845 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
14846 Insert_List_Before_And_Analyze after the generation of the specs
14847 associated with null procedures.
14848 (Expand_Tagged_Root): Update documentation in its specification.
14849 (Init_Secondary_Tags): Update documentation.
14850 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
14851 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
14852 then generate code to inherit the contents of the dispatch table
14853 directly from the ancestor.
14854 (Expand_Record_Controller): Insert controller component after tags of
14855 implemented interfaces.
14856 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
14857 create null procedure overridings when null procedures are inherited
14859 (Make_Null_Procedure_Specs): New procedure to generate null procedure
14860 declarations for overriding null primitives inherited from interfaces.
14861 (Is_Null_Interface_Procedure): New function in
14862 Make_Null_Procedure_Specs.
14863 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
14864 immediate ancestor of a tagged type is an abstract interface type we
14865 must generate the specification of the predefined primitives associated
14866 with controlled types (because the dispatch table of the ancestor is
14867 null and hence these entries cannot be inherited). This is required to
14868 elaborate well the dispatch table.

14873 Gary Dismukes <dismukes@adacore.com>
14874 Robert Dewar <dewar@adacore.com>
14876 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
14878 (Expand_N_In): Do validity checks on range
14879 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
14880 (Expand_N_Allocator): For "new T", if the object is constrained by
14881 discriminant defaults, allocate the right amount of memory, rather than
14882 the maximum for type T.
14883 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
14884 when the allocator is initialized by a build-in-place call, since the
14885 allocator is already rewritten as a reference to the function result,
14886 and this prevents an unwanted duplication of the function call.
14887 Add with and use of Exp_Ch6.
14888 (Expand_Allocator_Expresssion): Check for an allocator whose expression
14889 is a call to build-in-place function and apply
14890 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
14891 untagged designated types).
14892 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
14893 optimization if source or target is biased.
14894 (Expand_N_Allocator): Add comments for case of an allocator within a
14895 function that returns an anonymous access type designating tasks.
14896 (Expand_N_Allocator): apply discriminant checks for access
14897 discriminants of anonymous access types (AI-402, AI-416)
14899 2006-10-31 Bob Duff <duff@adacore.com>
14900 Robert Dewar <dewar@adacore.com>
14901 Gary Dismukes <dismukes@adacore.com>
14902 Ed Schonberg <schonberg@adacore.com>
14904 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
14906 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
14907 (Expand_N_Assignment_Statement): Call
14908 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
14909 build-in-place function call. Currently, this can happen only for
14910 assignments that come from aggregates.
14911 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
14912 in order to alleviate the upward compatibility introduced by AI-318.
14913 (Expand_N_Extended_Return_Statement): Add support for handling the
14914 return object as a build-in-place result.
14915 (Expand_Non_Function_Return): Implement simple return statements nested
14916 within an extended return.
14917 (Enable_New_Return_Processing): Turn on the new processing of return
14919 (Expand_Non_Function_Return): For a return within an extended return,
14920 don't raise Program_Error, because Sem_Ch6 now gives a warning.
14921 (Expand_N_Extended_Return_Statement): Implement AI-318
14922 (Expand_Simple_Function_Return): Ditto.
14923 (Expand_N_If_Statement): Handle new -gnatwt warning
14924 (Expand_N_Case_Statement): Handle new -gnatwt warning
14925 (Expand_N_Assignment): Handle assignment to the Priority attribute of
14926 a protected object.
14927 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
14928 validity checking of assignments to elementary record components.
14929 (Expand_N_Return_Statement): return Class Wide types on the secondary
14930 stack independantly of their controlled status since with HIE runtimes,
14931 class wide types are not potentially controlled anymore.
14933 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
14936 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
14937 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
14938 it expects a block, procedure, or task. The return statement will get
14939 turned into a block, and Expand_Cleanup_Actions will happen then.
14941 2006-10-31 Robert Dewar <dewar@adacore.com>
14942 Ed Schonberg <schonberg@adacore.com>
14943 Bob Duff <duff@adacore.com>
14944 Gary Dismukes <dismukes@adacore.com>
14946 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
14948 (Expand_Inlined_Call): Tagged types are by-reference types, and
14949 therefore should be replaced by a renaming declaration in the expanded
14950 body, as is done for limited types.
14951 (Expand_Call): If this is a call to a function with dispatching access
14952 result, propagate tag from context.
14953 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
14955 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
14956 build-in-place when the right-hand side of an assignment is a
14957 build-in-place function call.
14958 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
14959 of the explicit dereference of the allocator to the result subtype of
14960 the build-in-place function. This is needed to satisfy type checking
14961 in cases where the caller's return object is created by an allocator for
14962 a class-wide access type and the type named in the allocator is a
14964 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
14965 conversion of the reference to the declared object to the result subtype
14966 of the build-in-place function. This is needed to satisfy type checking
14967 in cases where the declared object has a class-wide type. Also, in the
14968 class-wide case, change the type of the object entity to the specific
14969 result subtype of the function, to avoid passing a class-wide object
14970 without explicit initialization to the back end.
14971 (Register_Interface_DT_Entry): Moved outside the body of
14972 Freeze_Subprogram because this routine is now public; it is called from
14973 Check_Dispatching_Overriding to handle late overriding of abstract
14974 interface primitives.
14975 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
14976 adding an implicit access actual on a call to a build-in-place function.
14977 (Expand_Actuals): Test for an actual parameter that is a call to a
14978 build-in-place function and apply
14979 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
14980 (Is_Build_In_Place_Function): New function to determine whether an
14981 entity is a function whose calls should be handled as build-in-place.
14982 (Is_Build_In_Place_Function_Call): New function to determine whether an
14983 expression is a function call that should handled as build-in-place.
14984 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
14985 calls to build-in-place functions as the initialization of an allocator.
14986 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
14987 handling calls to build-in-place functions in contexts that do not
14988 involve init of a separate object (for example, actuals of subprogram
14990 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
14991 handling calls to build-in-place functions as the initialization of an
14992 object declaration.
14993 (Detect_Infinite_Recursion): Add explicit parameter Process to
14994 instantiation of Traverse_Body to avoid unreferenced warning.
14995 (Check_Overriding_Inherited_Interfaces): Removed.
14996 (Register_Interface_DT_Entry): Code cleanup.
14997 (Register_Predefined_DT_Entry): Code cleanup.
14998 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
14999 inlined statements if within a transient scope.
15000 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
15001 formal parameters with occurrences of actuals in inlined body, establish
15002 visibility on the proper view of the actual's subtype for the body's
15004 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
15005 compatibility mode and we have an imported CPP subprogram because
15006 for now we assume that imported CPP primitives correspond with
15007 objects whose constructor is in the CPP side (and therefore we
15008 don't need to generate code to register them in the dispatch table).
15009 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
15010 aligned selected component.
15011 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
15012 the actual of an in-mode parameter is a type conversion.
15013 (Expand_Actuals): If the call does not come from source and the actual
15014 is potentially misaligned, let gigi handle it rather than rejecting the
15015 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
15016 Class Wide types as returning by reference independantly of their
15017 controlled status since with HIE runtimes class wide types are not
15018 potentially controlled anymore.
15020 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15022 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
15023 references that are private components of the protected object.
15024 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
15025 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
15026 instantiation to deal with warnings.
15027 (Initialize_Protection): If expression for priority is non-static, use
15028 System_Priority as its expected type, in case the expression has not
15031 2006-10-31 Robert Dewar <dewar@adacore.com>
15033 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
15034 initialization of Homonym_Len.
15035 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
15036 names from fully qualified name. Fixes problem of duplicate
15037 external names differing only in the presence of such a block name.
15039 2006-10-31 Thomas Quinot <quinot@adacore.com>
15040 Pablo Oliveira <oliveira@adacore.com>
15042 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
15043 subprogram Ids, even if they are not yet assigned.
15044 (Build_Subprogram_Id): It is now this function that will take care of
15045 calling Assign_Subprogram_Ids if necessary.
15046 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
15047 should be done only once they are assigned.
15048 (Build_From_Any_Function, case of tagged types): Add missing call to
15050 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
15051 type for an RACW type.
15052 (Add_RACW_Features): When processing an RACW declaration for which the
15053 designated type is already frozen, enforce E.2.2(14) rules immediately.
15054 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
15055 special reordering of controlling formals.
15057 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
15058 associated stub type for an RACW type.
15060 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15062 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
15063 fixed-point operations in an integer context, i.e. as operands of a
15064 conversion to an integer type, indicate that result must be rounded.
15066 2006-10-31 Robert Dewar <dewar@adacore.com>
15068 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
15069 cases, pass the encoding method, since it is now required by the run
15072 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
15073 assumption that Str'First = 1.
15074 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
15075 it on to the Value_Wide_Wide_Character call.
15076 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
15077 properly handles a string of the form quote-encoded_wide_char-quote.
15079 * s-wchcnv.adb: Minor reformatting
15081 2006-10-31 Javier Miranda <miranda@adacore.com>
15083 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
15084 run-time membership test to ensure that the constructed object
15085 implements the target abstract interface.
15087 2006-10-31 Robert Dewar <dewar@adacore.com>
15089 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
15090 Machine_Attribute pragma internally to implement the user pragma.
15091 Add processing for pragma Interface so that it is now completely
15092 equivalent to pragma Import.
15094 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
15095 so that it can be applied to all entities, including record components
15096 and enumeration literals.
15097 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
15098 priority ranges are correct, verify compatibility against task
15099 dispatching and locking policies, and if everything is correct an entry
15100 is added to the table containing priority specific dispatching entries
15101 for this compilation unit.
15102 (Delay_Config_Pragma_Analyze): Delay processing
15103 Priority_Specific_Dispatching pragmas because when processing the
15104 pragma we need to access run-time data, such as the range of
15105 System.Any_Priority.
15106 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
15107 Allow pragma Unreferenced as a context item
15108 Add pragma Preelaborable_Initialization
15109 (Analyze_Pragma, case Interface): Interface is extended so that it is
15110 now syntactically and semantically equivalent to Import.
15111 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
15112 insertion characters.
15113 Add handling for Pragma_Wide_Character_Encoding
15114 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
15115 never supercedes a real restriction, and that a real restriction
15116 always supercedes a warning.
15117 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

15124 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
15125 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
15126 Is_Inherently_Limited_Type, because return-by-reference has no meaning
15128 (Find_Node_To_Be_Wrapped): Use new method of determining the result
15129 type of the function containing a return statement, because the
15130 Return_Type field was removed. We now use the Return_Applies_To field.
15132 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
15133 (Build_Task_Image_Decl): If procedure is not called from an
15134 initialization procedure, indicate that function that builds task name
15135 uses the sec. stack. Otherwise the enclosing initialization procedure
15136 will carry the indication.
15137 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
15138 N_Object_Declaration instead.
15139 (Kill_Dead_Code): New interface to implement -gnatwt warning for
15140 conditional dead code killed, and change implementation accordingly.
15141 (Insert_Actions): Add N_Return_Object_Declaration case.
15142 Correct comment to mention N_Extension_Aggregate node.
15143 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
15144 attempts to save information for global variables which cannot be
15146 (Get_Current_Value_Condition): Handle conditions the other way round
15147 (constant on left). Also handle right operand of AND and AND THEN
15148 (Set_Current_Value_Condition): Corresponding changes
15149 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
15150 (Get_Current_Value_Condition): Handle simple boolean operands
15151 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
15152 (Get_Current_Value_Condition): If the variable reference is within an
15153 if-statement, does not appear in the list of then_statments, and does
15154 not come from source, treat it as being at unknown location.
15155 (Get_Current_Value_Condition): Enhance to allow while statements to be
15156 processed as well as if statements.
15157 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
15159 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
15160 of loop. This is safe now that we fixed Kill_Current_Values.
15161 (OK_To_Do_Constant_Replacement): Check whether current scope is
15162 Standard, before examining outer scopes.
15164 2006-10-31 Vincent Celier <celier@adacore.com>
15166 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
15167 When True, apply VMS treatment to children of packages A, G, I and S.
15170 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
15172 2006-10-31 Robert Dewar <dewar@adacore.com>

15185 (Generate_Reference): Accept an implicit reference generated for a
15186 default in an instance.
15187 (Generate_Reference): Accept a reference for a node that is not in the
15188 main unit, if it is the generic body corresponding to an subprogram
15191 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
15193 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
15195 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
15197 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
15198 use clauses, to avoid messages on packages used to qualify, and also
15199 to avoid messages from obsolescent units.
15200 (Warn_On_Useless_Assignments): Don't generate messages for imported
15201 and exported variables.
15202 (Warn_On_Useless_Assignments): New procedure

15204 (Check_Code_Statement): New procedure
15206 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
15207 Change name Is_Ada_2005 to Is_Ada_2005_Only
15208 (Last_Assignment): New field for useless assignment warning
15210 2006-10-31 Olivier Hainque <hainque@adacore.com>
15212 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
15213 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
15215 2006-10-31 Bob Duff <duff@adacore.com>
15216 Robert Dewar <dewar@adacore.com>
15217 Ed Schonberg <schonberg@adacore.com>
15219 * g-awk.adb (Default_Session, Current_Session): Compile this file in
15220 Ada 95 mode, because it violates the new rules for AI-318.
15222 * g-awk.ads: Use overloaded subprograms in every case where we used to
15223 have a default of Current_Session. This makes the code closer to be
15224 correct for both Ada 95 and 2005.
15226 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
15227 code, relying on the fact that the compiler generates a warning
15228 instead of an error in -gnatg mode.
15230 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
15231 E_Return_Statement entity kind.
15232 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
15234 * par.adb (P_Interface_Type_Definition): Addition of one formal to
15235 report an error if the reserved word abstract has been previously found.
15236 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
15238 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
15239 parenthesized range attribute usage
15240 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
15242 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
15243 in the syntax for extended_return_statement. This is not in the latest
15244 RM, but the ARG is expected to issue an AI allowing this.
15245 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
15246 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
15247 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
15248 P_Return_Statement): Parse the new syntax for extended_return_statement.
15250 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
15251 Output_End_Missing): Add error-recovery code for the new
15252 extended_return_statement syntax; that is, the new E_Return entry on
15255 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
15256 limited to nonlimited, because otherwise we violate the new Ada 2005
15257 rules about returning limited types in function Create_AST_Handler in
15260 * sem.adb (Analyze): Add cases for new node kinds
15261 N_Extended_Return_Statement and N_Return_Object_Declaration.
15263 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
15264 type is in the same category as type of context before applying check,
15265 to prevent anomalies in instantiations.
15266 (Resolve_Aggregate): Remove test for limited components in aggregates.
15267 It's unnecessary in Ada 95, because if it has limited components, then
15268 it must be limited. It's wrong in Ada 2005, because limited aggregates
15270 (Resolve_Record_Aggregate): Move check for limited types later, because
15271 OK_For_Limited_Init requires its argument to have been resolved.
15272 (Get_Value): When copying the component default expression for a
15273 defaulted association in an aggregate, use the sloc of the aggregate
15274 and not that of the original expression, to prevent spurious
15275 elaboration errors, when the expression includes function calls.
15276 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
15277 were missing. We also didn't handle qualified expressions. Now also
15278 allow function calls. Use new common routine OK_For_Limited_Init.
15279 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
15280 with space can upper case letter).
15282 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
15283 Has_Static_Discriminants flag
15284 (Record_Type_Declaration): Diagnose an attempt to declare an interface
15285 type with discriminants.

15287 (Build_Discriminant_Constraints): Use updated form of
15288 Denotes_Discriminant.
15289 (Process_Subtype): If the subtype is a private subtype whose full view
15290 is a concurrent subtype, introduce an itype reference to prevent scope
15292 (Build_Derived_Record_Type, Collect_Interface_Primitives,
15293 Record_Type_Declaration): The functionality of the subprograms
15294 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
15295 is now performed by a single routine.
15296 (Build_Derived_Record_Type): If the type definition includes an explicit
15297 indication of limitedness, then the type must be marked as limited here
15298 to ensure that any access discriminants will not be treated as having
15299 a local anonymous access type.
15300 (Check_Abstract_Overriding): Issue a detailed error message when an
15301 abstract subprogram was not overridden due to incorrect mode of its
15303 (Analyze_Private_Extension_Declaration): Add support for the analysis of
15304 synchronized private extension declarations. Verify that the ancestor is
15305 a limited or synchronized interface or in the generic case, the ancestor
15306 is a tagged limited type or synchronized interface and all progenitors
15307 are either limited or synchronized interfaces.
15308 Derived_Type_Declaration): Check for presence of private extension when
15309 dealing with synchronized formal derived types.
15310 Process_Full_View): Enchance the check done on the usage of "limited" by
15311 testing whether the private view is synchronized.
15312 Verify that a synchronized private view is completed by a protected or
15314 (OK_For_Limited_Init_In_05): New function.
15315 (Analyze_Object_Declaration): Move check for limited types later,
15316 because OK_For_Limited_Init requires its argument to have been resolved.
15317 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
15318 in order to alleviate the upward compatibility introduced by AI-318.
15319 (Constrain_Corresponding_Record): If the constraint is for a component
15320 subtype, mark the itype as frozen, to avoid out-of-scope references to
15321 discriminants in the back-end.
15322 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
15323 this subprogram against wrong sources.
15324 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
15325 discriminant of limited type completed with a protected type, when the
15326 discriminant is used to constrain a private component of the type, and
15327 expansion is disabled.
15328 (Find_Type_Of_Object): Do not treat a return subtype that is an
15329 anonymous subtype as a local_anonymous_type, because its accessibility
15330 level is the return type of the enclosing function.
15331 (Check_Initialization): In -gnatg mode, turn the error "cannot
15332 initialize entities of limited type" into a warning.
15333 (OK_For_Limited_Init): Return true for generated nodes, since it
15334 sometimes violates the legality rules.
15335 (Make_Incomplete_Declaration): If the type for which an incomplete
15336 declaration is created happens to be the currently visible entity,
15337 preserve the homonym chain when removing it from visibility.
15338 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
15339 inherited subprograms.
15340 (Access_Definition): If this is an access to function that is the return
15341 type of an access_to_function definition, context is a type declaration
15342 and the scope of the anonymous type is the current one.
15343 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
15344 incomplete subtype to the set of private dependents of the original
15346 (Constrain_Discriminated_Type): Emit an error message whenever an
15347 incomplete subtype is being constrained.
15348 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
15349 corresponding subtype of the full view of the original incomplete type.
15350 (Check_Incomplete): Properly detect invalid usage of incomplete types
15353 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>

15364 Robert Dewar <dewar@adacore.com>
15366 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
15367 handling executable extension manually and duplicating code.
15369 * make.adb: Implement new -S switch
15370 (Gnatmake): Use new function Osint.Executable_Name instead
15371 of handling executable extension manually.
15373 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
15374 is specified, the executable name ends with this suffix.
15375 Take advantage of Osint.Executable_Name instead of duplicating code.
15377 * switch-m.adb: Recognize new gnatmake -S switch
15379 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
15381 (Get_Target_Parameters): Set Executable_Extension_On_Target if
15384 * makeusg.adb: Add line for gnatmake -S switch
15386 2006-10-31 Vincent Celier <celier@adacore.com>
15388 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
15389 call it with -static-libgcc, as there are some platforms, such as
15390 Darwin, where one of these two switches is compulsory to link.
15392 2006-10-31 Vincent Celier <celier@adacore.com>
15394 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
15395 instead of ADA_PROJECT_PATH, for the project path.
15396 (Gnatls): When displaying the project path directories, use host dir
15399 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
15400 names in the project path, as absolute paths may correspond to
15401 multi-valued VMS logical names.
15403 2006-10-31 Vincent Celier <celier@adacore.com>
15405 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
15406 absolute path name.
15407 (Locate_Regular_File): Ditto
15408 (Change_Dir): Remove, no longer used
15409 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
15410 on Windows. Get it calling Get_Current_Dir.
15411 (OpenVMS): Remove imported boolean, no longer needed.
15412 (Normalize_Pathname)[VMS]: Do not resolve directory names.
15413 (Pid_To_Integer): New function to convert a Process_Id to Integer
15415 2006-10-31 Thomas Quinot <quinot@adacore.com>
15417 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
15418 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
15420 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
15423 2006-10-31 Robert Dewar <dewar@adacore.com>

15430 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
15432 2006-10-31 Robert Dewar <dewar@adacore.com>
15434 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
15436 (Layout_Variant_Record): Retrieve the discriminants from the entity
15437 rather than from the type definition, because in the case of a full
15438 type for a private type we need to take the discriminants from the
15440 (Layout_Component_List): When applying the Max operator to variants with
15441 a nonstatic size, check whether either operand is static and scale that
15442 operand from bits to storage units before applying Max.
15443 (Layout_Type): In VMS, if a C-convention access type has no explicit
15444 size clause (and does not inherit one in the case of a derived type),
15445 then the size is reset to 32 from 64.
15447 2006-10-31 Vincent Celier <celier@adacore.com>
15449 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
15450 its file has already been loaded, according to the unit being loaded,
15451 not to the current value of Multiple_Unit_Index.
15453 2006-10-31 Thomas Quinot <quinot@adacore.com>
15454 Eric Botcazou <ebotcazou@adacore.com>

15486 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
15489 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15491 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
15492 Process_Body_Clauses): If the context of a body includes a use clause
15493 for P.Q then a with_clause for P in the same body is not redundant,
15494 even if the spec also has a with_clause on P.
15495 Add missing continuation mark to error msg
15496 (Build_Limited_Views): A limited view of a type is tagged if its
15497 declaration includes a record extension.
15498 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
15499 node, even if the subunit has errors. This avoids malfunction by
15500 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
15501 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
15502 generation of obsolescent messages for with statements (cannot do
15503 this too early, or we cannot implement avoiding the messages in the
15504 case of obsolescent units withing obsolescent units).
15505 (Install_Siblings): If the with_clause is on a remote descendant of
15506 an ancestor of the current compilation unit, find whether there is
15507 a sibling child unit that is immediately visible.
15508 (Remove_Private_With_Clauses): New procedure, invoked after completing
15509 the analysis of the private part of a nested package, to remove from
15510 visibility the private with_clauses of the enclosing package
15512 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
15513 now centralized in Generate_Reference.
15514 (Install_Limited_Context_Clauses): Remove superfluous error
15515 message associated with unlimited view visible through use
15516 and renamings. In addition, at the point in which the error
15517 is reported, we add the backslash to the text of the error
15518 to ensure that it is reported as a single error message.
15519 Use new // insertion for some continuation messages
15520 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
15521 to create implicit with_clause for parent unit mentioned in original
15522 limited_with_clause.
15523 (Install_Limited_With_Unit): Set entity of parent identifiers if the
15524 unit is a child unit. For ASIS queries.
15525 (Analyze_Subunit): If the subunit appears within a child unit, make all
15526 ancestor child units directly visible again.

15541 a formal object declaration with an access definition or a subtype mark
15542 with a null exclusion.
15543 (P_Generic_Association): Handle association with box, and others_choice
15544 with box, to support Ada 2005 partially parametrized formal packages.
15546 2006-10-31 Robert Dewar <dewar@adacore.com>
15547 Javier Miranda <miranda@adacore.com>
15549 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
15550 (P_Type_Declaration): Remove barrier against the reserved word "limited"
15551 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
15552 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
15553 private extensions.
15554 (P_Type_Declaration): Add the new actual Abstract_Present to every call
15555 to P_Interface_Type_Definition.

15557 if the reserved word abstract has been previously found.
15558 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
15559 object renaming declaration with an access definition or subtype mark
15560 with a possible null exclusion.

15579 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
15582 2006-10-31 Vincent Celier <celier@adacore.com>
15584 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
15585 on VMS, change "__" to '.' before checking the name.
15586 (Record_Ada_Source): Always add the source file name in the list of
15587 of sources, even if it is not the first time, as it is for another
15589 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
15590 dot, instead of replacing only the first '_'.
15592 * prj-part.adb (Parse): Convert project file path to canonical form
15594 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
15595 extended, the project id of the project extending it is recorded in its
15596 data, even when it has already been processed as an imported project.
15598 2006-10-31 Robert Dewar <dewar@adacore.com>
15600 * repinfo.adb (List_Entities): Don't list entities from renaming

15604 Robert Dewar <dewar@adacore.com>
15606 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
15607 only a restriction warning is active for the given restriction. This is
15608 desirable because we do not want to modify code in the case where only
15610 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
15611 causes overriding of real restrictions.
15612 Take advantage of new No_Restrictions constant.
15614 * raise.h: (__gnat_set_globals): Change profile.
15616 2006-10-31 Arnaud Charlet <charlet@adacore.com>
15618 * rtsfind.adb: Remove s-polint from comment as it exists no more.

15643 (OK_Self_Reference): New subprogram to check the legality of an access
15644 attribute whose prefix is the type of an enclosing aggregate.
15645 Generalizes previous mechanism to handle attribute references nested
15646 arbitrarily deep within the aggregate.
15647 (Analyze_Access_Attribute): An access attribute whose prefix is a type
15648 can appear in an aggregate if this is a default-initialized aggregate
15649 for a self-referential type.
15650 (Resolve_Attribute, case Access): Ditto.
15651 Add support for new implementation defined attribute Stub_Type.
15652 (Eval_Attribute, case Attribute_Stub_Type): New case.
15653 (Analyze_Attribute, case Attribute_Stub_Type): New case.
15654 (Stream_Attribute_Available): Implement using new subprogram from

15656 Has_Specified_Stream_Attribute flag.
15657 Disallow Storage_Size and Storage_Pool for access to subprogram
15658 (Resolve_Attribute, case 'Access et al): Take into account anonymous
15659 access types of return subtypes in extended return statements. Remove
15660 accessibility checks on anonymous access types when Unchecked_Access is
15662 (Analyze_Attribute): Add support for the use of 'Class to convert
15663 a class-wide interface to a tagged type.
15664 Add support for the attribute Priority.
15665 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
15666 whether the designated type is discriminated with a constrained partial
15667 view and require static matching in that case.
15668 Add local variable Des_Btyp. The Designated_Type
15669 of an access to incomplete subtype is either its non-limited view if
15670 coming from a limited with or its etype if regular incomplete subtype.
15672 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
15673 Fix predicate to identify and allow cases of (expander-generated)
15674 references to tag of designated object of a RACW.
15675 (Validate_Static_Object_Name): In Ada 2005, a formal object is
15676 non-static, and therefore cannot appear as a primary in a preelaborable
15678 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
15679 Has_Read_Write_Attributes.
15680 (Has_Read_Write_Attributes): Reimplement in termes of
15681 Has_Stream_Attribute_Definition.

15686 2006-10-31 Robert Dewar <dewar@adacore.com>
15688 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
15689 useless assignments here and conditionalize it on absence of exception
15691 (Analyze_Exception_Handlers): Small code reorganization of error
15692 detection code, for new handling of formal packages.
15694 2006-10-31 Ed Schonberg <schonberg@adacore.com>

15701 generated private extension declaration if the formal derived type is
15702 synchronized. Carry synchronized present over to the generated private
15704 (Validate_Derived_Type_Instance): Ensure that the actual of a
15705 synchronized formal derived type is a synchronized tagged type.
15706 (Instantiate_Formal_Package): When creating the instantiation used to
15707 validate the actual package of a formal declared without a box, check
15708 whether the formal itself depends on a prior actual.
15709 (Instantiate_Formal_Subprogram): Create new entities for the defining
15710 identifiers of the formals in the renaming declaration, for ASIS use.
15711 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
15712 a renaming declaration or a subtype declaration for an actual in an
15713 instance, capture location information of declaration in generic, for
15715 (Instantiate_Formal_Package): Add comments on needed additional tests.
15716 AI-317 (partial parametrization) is fully implemented.
15717 (Validate_Private_Type_Instance): Add check for actual which
15718 must have preelaborable initialization
15719 Use new // insertion for some continuation messages
15720 (Analyze_Formal_Object_Declaration): Change usage of Expression to
15721 Default_Expression. Add type retrieval when the declaration has an
15722 access definition. Update premature usage of incomplete type check.
15723 (Check_Access_Definition): New subsidiary routine. Check whether the
15724 current compilation version is Ada 05 and the supplied node has an
15726 (Instantiate object): Alphabetize local variables. Handle the creation
15727 of new renaming declarations with respect to the kind of definition
15728 used - either an access definition or a subtype mark. Guard against
15729 unnecessary error message in the context of anonymous access types after
15730 they have been resolved. Add check for required null exclusion in a
15731 formal object declaration.
15732 (Switch_View): A private subtype of a non-private type needs to be
15733 switched (the base type can have been switched without its private
15734 dependents because of the last branch of Check_Private_View.
15735 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
15737 (Instantiate_Type): Emit an error message whenever a class-wide type of
15738 a tagged incomplete type is used as a generic actual.
15739 (Find_Actual_Type): Extend routine to handle a component type in a child
15740 unit that is imported from a formal package in a parent.
15741 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
15742 agree on constrainedness, rather than checking against ultimate ancestor
15743 (Instantiate_Subprogram_Body): Create a cross-reference link to the
15744 generic body, for navigation purposes.

15747 Thomas Quinot <quinot@adacore.com>
15749 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
15751 (New_Stream_Subprogram): When processing an attribute definition clause
15752 for a stream-oriented subprogram, record an entity node occurring at
15753 the point of clause to use for checking the visibility of the clause,
15754 as defined by 8.3(23) as amended by AI-195.
15755 (New_Stream_Subprogram): New procedure, factoring behaviour from both
15756 New_Stream_Function and New_Stream_Procedure.
15757 (New_Stream_Function, New_Stream_Procedure): Removed.
15758 (Analyze_Attribute_Definition_Clause, case Address): Check new
15759 Alignment_Check check

15762 Javier Miranda <miranda@adacore.com>
15763 Robert Dewar <dewar@adacore.com>
15765 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
15766 generate the same errors compiling under -gnatc.
15767 (Try_Object_Operation): If no candidate interpretation succeeds, but
15768 there is at least one primitive operation with the right name, report
15769 error in call rather than on a malformed selected component.
15770 (Analyze_Selected_Component): If the prefix is an incomplete type from
15771 a limited view, and the full view is available, use the full view to
15772 determine whether this is a prefixed call to a primitive operation.
15773 (Operator_Check): Verify that a candidate interpretation is a binary
15774 operation before checking the type of its second formal.
15775 (Analyze_Call): Add additional warnings for function call contexts not
15777 (Analyze_Allocator): Move the check for "initialization not allowed for
15778 limited types" after analyzing the expression. This is necessary,
15779 because OK_For_Limited_Init looks at the structure of the expression.
15780 Before analysis, we don't necessarily know what sort of expression it
15781 is. For example, we don't know whether F(X) is a function call or an
15782 indexed component; the former is legal in Ada 2005; the latter is not.
15783 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
15784 were missing. We also didn't handle qualified expressions. Now also
15785 allow function calls. Use new common routine OK_For_Limited_Init.
15786 (Analyze_Type_Conversion): Do not perform some legality checks in an
15787 instance, because the error message will be redundant or spurious.
15788 (Analyze_Overloaded_Selected_Component): Do not do style check when
15789 setting an entity, since we do not know it is the right entity yet.
15790 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
15791 (Analyze_Overloaded_Selected_Component): Same change
15792 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
15793 since regular incomplete subtypes are transformed into corresponding
15794 subtypes of their full views.
15795 (Complete_Object_Operation): Treat name of transformed subprogram call
15796 as coming from source, for browsing purposes.
15797 (Try_Primitive_Operation): If formal is an access parameter, compare
15798 with base type of object to determine whether it is a primitive
15800 (Operator_Check): If no interpretation of the operator matches, check
15801 whether a use clause on any candidate might make the operation legal.
15802 (Try_Class_Wide_Operation): Check whether the first parameter is an
15803 access type whose designated type is class-wide.

15809 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
15810 warn on infinite loops.
15811 Add \\ to some continuation messages
15812 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
15813 (Process_Bounds): If the bounds are integer literals that result from
15814 constant-folding, and they carry a user-defined type, preserve that type
15815 rather than treating this as an integer range.
15816 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
15817 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
15818 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
15819 left hand side of assignment.
15820 (Analyze_Assignment): Add suport to manage assigments to the attribute
15821 priority of a protected object.
15822 (Check_Possible_Current_Value_Condition): Allow fully qualified names
15823 not just identifiers.
15824 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
15825 or AND THEN for possible tracking.
15826 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
15827 case of while loops so we can track values in the loop body.

15831 Bob Duff <duff@adacore.com>
15833 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
15834 procedure cannot be a protected operation (it is a basic_declaration,
15835 not a subprogram_declaration).
15836 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
15837 Subp. Add logic for entry processing.
15838 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
15839 Determine whether an entry or subprogram of a protected or task type
15840 override an inherited primitive of an implemented interface.
15841 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
15842 Update the actual used in calls to Check_Overriding_Indicator.
15843 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
15844 generate the proper reference to the parent unit, for cross-reference.
15845 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
15847 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
15848 (Add_Extra_Formal): Revise procedure to allow passing in associated
15849 entity, scope, and name suffix, and handle setting of the new
15850 Extra_Formals field.
15851 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
15852 pass new parameters. Add support for adding the new extra access formal
15853 for functions whose calls are treated as build-in-place.
15854 (Analyze_A_Return_Statement): Correct casing in error message.
15855 Move Pop_Scope to after Analyze_Function_Return, because an extended
15856 return statement really is a full-fledged scope. Otherwise, visibility
15857 doesn't work right. Correct use of "\" for continuation messages.
15858 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
15859 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
15860 the node doesn't get properly marked as analyzed.
15861 (Analyze_Subprogram_Body): If subprogram is a function that returns
15862 an anonymous access type that denotes a task, build a Master Entity
15864 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
15865 proper usage of null exclusion in a result definition.
15866 (Process_Formals): Code cleanup and new error message.
15867 (Process_Formals): Detect incorrect application of null exclusion to
15869 (Conforming_Types): Handle conformance between [sub]types and itypes
15870 generated for entities that have null exclusions applied to them.
15871 (Maybe_Primitive_Operation): Add an additional type retrieval when the
15872 base type is an access subtype. This case arrises with null exclusions.
15873 (New_Overloaded_Entity): Do not remove the overriden entity from the
15874 homonym chain if it corresponds with an abstract interface primitive.
15875 (Process_Formals): Replace membership test agains Incomplete_Kind with a
15876 call to the synthesized predicate Is_Incomplete_Type.
15877 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
15879 (Analyze_Subprogram_Declaration): Check that abstract interface
15880 primitives are abstract or null.
15881 (Analyze_Subprogram_Specification): Remove previous check for abstract
15882 interfaces because it was not complete.
15883 (Has_Interface_Formals): Removed.

15886 Javier Miranda <miranda@adacore.com>
15888 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
15889 of Analyze_Package_Body, to create Itype references for anonymous
15890 access types created in the package declaration, whose designated types
15891 may have only a limited view.
15892 (Analyze_Package_Specification): For the private part of a nested
15893 package, install private_with_clauses of enclosing compilation unit if
15894 we are in its visible part.
15895 (Declare_Inherited_Private_Subprograms): Complete barrier
15896 to ensure that the primitive operation has an alias to some parent
15897 primitive. This is now required because, after the changes done for the
15898 implementation of abstract interfaces, the contents of the list of
15899 primitives has entities whose alias attribute references entities of
15900 such list of primitives.
15901 (Analyze_Package_Specification): Simplify code that handles parent units
15902 of instances and formal packages.
15903 (Uninstall_Declarations): Check the convention consistency among
15904 primitive overriding operations of a tagged record type.

15909 Ed Schonberg <schonberg@adacore.com>
15911 * sem_ch8.adb: Minor error msg rewording
15912 (Undefined): When checking for misspellings, invert arguments (to get
15913 expected and found set right)
15914 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
15915 (Analyze_Generic_Renaming): Same fix
15916 (Use_One_Package): Do not take into account the internal entities of
15917 abstract interfaces during the analysis of entities that are marked
15918 as potentially use-visible.
15919 (Find_Type): Handle the case of an attribute reference for
15920 implementation defined attribute Stub_Type (simply let the analysis of
15921 the attribute reference rewrite it).
15922 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
15923 type that appears in a Use_Type clause.
15924 (Analyze_Object_Renaming): Add support for renaming of the Priority
15926 (Find_Type): In Ada 2005, a task type can be used within its own body,
15927 when it appears in an access definition.
15928 (Analyze_Object_Renaming): Remove warning on null_exclusion.
15929 (Analyze_Object_Renaming): Introduce checks for required null exclusion
15930 in a formal object declaration or in a subtype declaration.
15931 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
15932 (Check_Null_Exclusion): New local routine to
15933 Analyze_Subprogram_Renaming. Check whether the formals and return
15934 profile of a renamed subprogram have required null exclusions when
15935 their counterparts of the renaming already impose them.
15936 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
15937 Determine whether an entity is inside a generic scope.
15938 (In_Open_Scope): First pass of documentation update.
15939 (Find_Expanded_Name): Add support for shadow entities associated with
15940 limited withed packages. This is required to handle nested packages.
15941 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
15942 that makes a renaming of a limited withed package illegal.

15947 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
15948 Check_Overriding_Indicator.
15949 (Analyze_Task_Definition): Ditto.
15950 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
15951 (Check_Overriding_Indicator): To find overridden interface operation,
15952 examine only homonyms that have an explicit subprogram declaration, not
15953 inherited operations created by an unrelated type derivation.
15954 (Check_Overriding_Indicator): When checking for the presence of "null"
15955 in a procedure, ensure that the queried node is a procedure
15957 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
15958 type when the formal is an access to variable.
15959 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
15960 (Analyze_Task_Type): Same addition
15961 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to

15969 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
15970 inherited from an interface ancestor by another interface in the
15971 context of an instance as 'late'.
15972 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
15973 of a call to a function that dispatches on access result.
15974 (Check_Dispatching_Operation): In case of late overriding of a primitive
15975 that covers abstract interface subprograms we register it in all the
15976 secondary dispatch tables associated with abstract interfaces.
15977 (Check_Dispatching_Call): Add check that a dispatching call is not made
15978 to a function with a controlling result of a limited type. This is a
15979 current implementation restriction.
15980 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
15981 (Check_Dispatching_Operation): Do no emit a warning if the controlling
15982 argument is an interface type that is a generic formal.
15983 (Is_Interface_Subprogram): Removed.
15984 (Check_Dispatching_Operation): If the subprogram is not a dispatching
15985 operation, check the formals to handle the case in which it is
15986 associated with an abstract interface type.

16003 Hristian Kirtchev <kirtchev@adacore.com>
16004 Javier Miranda <miranda@adacore.com>
16006 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
16007 subprogram type to provide better diagnostics in case of ambiguity.
16008 (Covers): Handle coverage of formal and actual anonymous access types in
16009 the context of generic instantiation.
16010 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
16011 abstract interface types; this is required to handle concurrent types
16012 with discriminants and abstract interface types.
16013 (Covers): Include type coverage of both regular incomplete subtypes and
16014 incomplete subtypes of incomplete type visibles through a limited with

16026 Add missing continuation marks in error msgs
16027 (Unqualify): New function for removing zero or more levels of
16028 qualification from an expression. There are numerous places where this
16029 ought to be used, but we currently only deal properly with zero or one
16031 (In_Instance); The analysis of the actuals in the instantiation of a
16032 child unit is not within an instantiation, even though the parent
16033 instance is on the scope stack.
16034 (Safe_To_Capture_Value): Exclude the case of variables that are
16036 (Check_Obsolescent): Removed
16037 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
16038 is an aliased view, even when rewritten as a reference to the target
16039 object in an assignment.
16040 (Get_Subprogram_Entity): New function
16041 (Known_To_Be_Assigned): New function
16042 (Type_Access_Level): Compute properly the access level of a return

16049 has a null exclusion depending on its Nkind.
16050 Change Is_Lvalue to May_Be_Lvalue
16051 (May_Be_Lvalue): Extensive additional code to deal with subprogram
16052 arguments (IN parameters are not Lvalues, IN OUT parameters are).
16053 (Safe_To_Capture_Value): Extend functionality so it can be used for
16054 the current value condition case.
16055 (Has_Compatible_Alignment): New function
16056 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
16057 objects to handle the Ada 2005 case, where aliasedness no longer implies
16058 that the object is constrained. In particular, for dereferenced names,
16059 the designated object must be assumed to be unconstrained.
16060 (Kill_Current_Values): Properly deal with the case where we encounter
16061 a loop in the scope chain.
16062 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
16064 (Compile_Time_Constraint_Error): Improve error message in error case

16070 2006-10-31 Robert Dewar <dewar@adacore.com>
16072 * s-osinte-tru64.adb:
16073 Mark Asm statements Volatile to prevent warnings (seems a
16074 reasonable change anyway)
16077 * s-mastop-irix.adb: Add Volatile to Asm statements
16078 Suppresses warning, and seems appropriate in any case
16080 * s-osinte-vms.adb: Add Volatile to Asm statement

16094 Private_Extension_Declaration to the list of assertions.
16095 (Is_Entry_Barrier_Function): New flag
16096 (Has_Self_Reference): New flag on aggregates, to indicate that they
16097 contain a reference to the enclosing type, inserted through a default
16099 (Next_Rep_Item): Move from Node4 to Node5.
16100 (Entity): Add this field for N_Attribute_Definition_Clause.
16101 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
16102 (N_Return_Object_Declaration): Remove this node kind. We now use
16103 N_Object_Declaration instead.
16104 (Actual_Designated_Subtype): Move to a different place to make room in
16105 N_Extended_Return_Statement.
16106 (Procedure_To_Call): Move to a different place to make room in
16107 N_Extended_Return_Statement.
16108 (Return_Type): Removed this field to make room in return statements
16110 (Return_Statement_Entity): New field in return statements, in part to
16111 replace Return_Type, and in part to support the fact that return
16112 statements are now pushed on the scope stack during semantic analysis.
16113 (Return_Object_Declarations): New field to support extended return
16115 (N_Extended_Return_Statement): New node for extended_return_statement
16117 (N_Return_Object_Declaration): New node for part of
16118 extended_return_statement nonterminal. Needed because all the necessary
16119 fields won't fit in N_Extended_Return_Statement.
16120 Generic_associations now carry the Box_Present flag, to indicate a
16121 default for an actual in a partially parametrized formal package.
16123 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
16124 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma
16125 and for the new predefined dispatching policies: EDF_Across_Priorities,

16127 Introduce new name Stub_Type for implementation defined attribute.
16128 Add pragma Preelaborable_Initialization
16129 Add entry for Priority attribute.

16139 print null exclusion twice in the case of an access definition,
16140 Implement new -gnatL switch

16719 Robert Dewar <dewar@adacore.com>
16721 * exp_ch4.adb (Expand_N_Allocator): If the allocated object is accessed
16722 through an access to class-wide interface we force the displacement of
16723 the pointer to the allocated object to reference the corresponding
16724 secondary dispatch table.
16725 (Expand_N_Op_Divide): Allow 64 bit divisions by small power of 2,
16726 if Long_Shifts are supported on the target, even if 64 bit divides
16727 are not supported (configurable run time mode).

16745 the bounds of the discriminant type are not static.
16747 2006-02-17 Robert Dewar <dewar@adacore.com>
16749 * g-os_lib.adb (Copy_File): Make sure that if From has an Invalid_FD,
16750 then we close To if it is valid.

16760 * Makefile.in: Use VMS64 specialized versions of several units in
16761 Interfaces.C hierarchy to be compatible with HP C default size choices.
16762 Use the default version of Ada.Synchronous_Task_Control for VxWorks 653.

16766 * sem_ch10.adb (Analyze_With_Clause): If the unit is a subprogram
16767 instantiation, the corresponding entity is the related_instance of the

16776 Ed Schonberg <schonberg@adacore.com>
16778 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
16779 type we cannot inherit the primitive operations; we inherit the
16780 Corresponding_Record_Type (which has the list of primitive operations).
16781 (Check_Anonymous_Access_Types): When creating anonymous access types for
16782 access components, use Rewrite in order to preserve the tree structure,
16784 (Analyze_Object_Declaration): For limited types with access
16785 discriminants with defaults initialized by an aggregate, obtain
16786 subtype from aggregate as for other mutable types.
16787 (Derived_Type_Declaration): If the derived type is a limited interface,
16788 set the corresponding flag (Is_Limited_Record is not sufficient).

16797 2006-02-17 Javier Miranda <miranda@adacore.com>
16799 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
16800 abstract interface type, the static analysis is not enough to know if
16801 the interface is implemented or not by the source tagged type. Hence
16802 we must pass the work to the expander to generate the required code to
16803 evaluate the conversion at run-time.
16804 (Resolve_Equality_Op): Do not apply previous
16805 transformation if expansion is disasbled, to prevent anomalies when
16806 locating global references in a generic unit.

16985 * system-mingw.ads (Underlying_Priorities): Update the priority mapping
16986 table to take advantage of the 16 priority levels available on Windows
16987 2000 and XP. On NT4 there are only 7 priority levels, this is properly
16988 supported by this new mapping.

17034 (Read): Change the implementation to support unicode characters. It is
17035 not possible to use strlen() on Windows as this version supports only
17036 standard ASCII characters. So the length of the directory entry is now
17037 returned from the imported __gnat_readdir routine.

17075 E_Floating_Point_Subtype>: Inherit alias set of what we are making a
17076 subtype of to ensure conflicts amongst all subtypes in a hierarchy,
17077 necessary since these are not different types and pointers may
17078 actually designate any subtype in this hierarchy.
17079 (gnat_to_gnu_entity, case E_Record_Type): Always make fields for
17080 discriminants but put them into record only if not Unchecked_Union;
17081 pass flag to components_to_record showing Unchecked_Union.
17082 (make_dummy_type): Use UNION_TYPE only if Unchecked_Union and no
17083 components before variants; don't set TYPE_UNCHECKED_UNION_P.
17084 (components_to_record): New argument UNCHECKED_UNION.
17085 Remove special case code for Unchecked_Union and instead use main code
17086 with small changes.
17089 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
17090 variable with the expression being built, only its inner field.
17092 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Remove call to
17093 emit_sequence_entry_statements.
17094 (emit_sequence_entry_statements, body_with_handlers_p): Delete.

17098 for a subprogram if it has a foreign convention or is exported.
17099 (Identifier_to_gnu): Manually unshare the DECL_INITIAL tree when it is
17100 substituted for a CONST_DECL.
17101 (tree_transform, case N_Aggregate): Remove code for UNION_TYPE and pass
17102 Etype to assoc_to_constructor.
17103 (assoc_to_constructor): New argument, GNAT_ENTITY; use it to ignore
17104 discriminants of Unchecked_Union.
17105 (TARGET_ABI_OPEN_VMS): Define to 0 if not defined, so that later uses

17596 containing secondary dispatch tables has discriminants to generate the
17597 correct arguments to call Set_Offset_To_Top.
17598 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
17600 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
17601 Add Wide_[Wide_]Expanded_Name.
17602 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
17603 the same functionality of Get_Prim_Op_Address but applied to predefined
17604 primitive operations because the pointers to the predefined primitives
17605 are now saved in a separate table.
17606 (Parent_Size): Modified to get access to the separate table of primitive
17607 operations or the parent type.
17608 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
17609 functionality of Set_Prim_Op_Address but applied to predefined primitive
17611 (Set_Signature): New subprogram used to store the signature of a DT.
17612 (Displace): If the Offset_To_Top value is not static then call the
17613 function generated by the expander to get such value; otherwise use
17614 the value stored in the table of interfaces.
17615 (Offset_To_Top): The type of the actual has been changed to Address to
17616 give the correct support to tagged types with discriminants. In this
17617 case this value is stored just immediately after the tag field.
17618 (Set_Offset_To_Top): Two new formals have been added to indicate if the
17619 offset_to_top value is static and hence pass this value to the run-time
17620 to store it in the table of interfaces, or else if this value is dynamic
17621 and then pass to the run-time the address of a function that is
17622 generated by the expander to provide this value for each object of the
17625 * rtsfind.ads (Default_Prin_Op_Count): Removed.
17626 (Default_Prim_Op_Count): New entity
17627 (Get_Predefined_Prim_Op_Address): New entity
17628 (Set_Predefined_Prim_Op_Address): New entity
17629 (RE_Set_Signature): New entity
17631 2006-02-13 Thomas Quinot <quinot@adacore.com>
17632 Ed Schonberg <schonberg@adacore.com>
17634 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
17635 Make_Adjust_Call done for a newly-allocated object.
17637 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
17638 in a subprogram are wrapped in a cleanup block, indicate that the
17639 subprogram contains an inner block with an exception handler.
17640 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
17641 Adjust call is for a newly-allocated object. In that case we must not
17642 assume that the finalization list chain pointers are correct (since they
17643 come from a bit-for-bit copy of the original object's pointers) so if
17644 the attach level would otherwise be zero (no change), we set it to 4
17645 instead to cause the pointers to be reset to null.
17647 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
17648 reset chain pointers to null.
17650 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17652 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
17653 string, and the context requires a loop for the assignment (e.g.
17654 because the left-hand side is packed), generate a unique name for the
17655 temporary that holds the string, to prevent spurious name clashes.
17657 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17658 Javier Miranda <miranda@adacore.com>
17659 Robert Dewar <dewar@adacore.com>
17660 Gary Dismukes <dismukes@adacore.com>
17662 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
17663 return unconstrained arrays.
17665 (Expand_Call): An indirect call through an access parameter of a
17666 protected operation is not a protected call.
17667 Add circuit to raise CE in Ada 2005 mode following call
17668 to Raise_Exception.
17669 (Register_DT_Entry): Do nothing if
17670 the run-time does not give support to abstract interfaces.
17671 (Freeze_Subprogram): In case of dispatching operations, do not generate
17672 code to register the operation in the dispatch table if the source
17673 is compiled with No_Dispatching_Calls.
17674 (Register_Predefined_DT_Entry): Generate code that calls the new
17675 run-time subprogram Set_Predefined_Prim_Op_Address instead of
17676 Set_Prim_Op_Address.
17678 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
17679 on array assignments if the right-hand side is a function call that has
17680 been inlined. Check is performed on the assignment in the block.
17681 (Process_Bounds): If bounds and range are overloaded, apply preference
17682 rule for root operations to disambiguate, and diagnose true ambiguity.
17683 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
17684 a tag-indeterminate right-hand side even when Expander_Active is True.
17685 Needed to ensure that dispatching calls to T'Input are allowed and
17686 get the tag of the target class-wide object.
17688 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
17689 an inherited primitive operation that already overrides several
17690 abstract interface primitives. For transitivity, the new entity must
17691 also override all the abstract interface primitives covered by the
17692 inherited overriden primitive.
17693 Emit warning if new entity differs from homograph in same scope only in
17694 that one has an access parameter and the other one has a parameter of
17695 a general access type with the same designated type, at the same
17696 position in the signature.
17697 (Make_Inequality_Operator): Use source locations of parameters and
17698 subtype marks from corresponding equality operator when creating the
17699 tree structure for the implicit declaration of "/=". This does not
17700 change anything in behaviour except that the decoration of the
17701 components of the subtree created for "/=" allows ASIS to get the
17702 string images of the corresponding identifiers.
17703 (Analyze_Return_Statement): Remove '!' in warning message.
17704 (Check_Statement_Sequence): Likewise.
17705 (Analyze_Subprogram_Body): For an access parameter whose designated type
17706 is an incomplete type imported through a limited_with clause, use the
17707 type of the corresponding formal in the body.
17708 (Check_Returns): Implicit return in No_Return procedure now raises
17709 Program_Error with a compile time warning, instead of beging illegal.
17710 (Has_Single_Return): Function returning unconstrained type cannot be
17711 inlined if expression in unique return statement is not an identifier.
17712 (Build_Body_To_Inline): It is possible to inline a function call that
17713 returns an unconstrained type if all return statements in the function
17714 return the same local variable. Subsidiary procedure Has_Single_Return
17715 verifies that the body conforms to this restriction.
17717 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
17718 same type, and one of them is of an anonymous access type, convert
17719 the other operand to it, so that this is a valid binary operation for
17721 (Resolve_Type_Conversion): Handle subtypes of protected types and
17722 task types when accessing to the corresponding record type.
17723 (Resolve_Allocator): Add '\' in 2-line warning message.
17724 Remove '!' in warning message.
17725 (Resolve_Call): Add '\' in 2-line warning message.
17726 (Valid_Conversion): Likewise.
17727 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
17728 resulting type may be an access type with an implicit dereference.
17729 Obtain the proper component from the designated type.
17730 (Make_Call_Into_Operator): Handle properly a call to predefined equality
17731 given by an expanded name with prefix Standard, when the operands are
17732 of an anonymous access type.
17733 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
17734 Explicit_Dereference and Resolve_Selected_Component, to verify that the
17735 prefix of the expression is not of an incomplete type. Allows full
17736 diagnoses of all semantic errors.
17737 (Resolve_Actuals): If the actual is an allocator whose directly
17738 designated type is a class-wide interface we build an anonymous
17739 access type to use it as the type of the allocator. Later, when
17740 the subprogram call is expanded, if the interface has a secondary
17741 dispatch table the expander will add a type conversion to force
17742 the displacement of the pointer.
17743 (Resolve_Call): If a function that returns an unconstrained type is
17744 marked Inlined_Always and inlined, the call will be inlined and does
17745 not require the creation of a transient scope.
17746 (Check_Direct_Boolean_Op): Removed
17747 (Resolve_Comparison_Op): Remove call to above
17748 (Resolve_Equality_Op): Remove call to above
17749 (Resolve_Logical_Op): Inline above, since this is only call.
17750 (Valid_Conversion): Handle properly conversions between arrays of
17751 convertible anonymous access types.
17754 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
17755 the literal in an unchecked conversion, because GCC 4.x needs a static
17756 value for a string bound.
17758 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17759 Hristian Kirtchev <kirtchev@adacore.com>
17761 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
17762 components of the corresponding record, take into account component
17763 definitions that are access definitions.
17764 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
17765 procedure is not considered a dispatching call and will be expanded
17768 2006-02-13 Javier Miranda <miranda@adacore.com>
17770 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
17771 controlling argument of the dispatching call is an abstract interface
17772 class-wide type then we use it directly.
17773 Check No_Dispatching_Calls restriction.
17774 (Default_Prim_Op_Position): Remove the code that looks for the last
17775 entity in the list of aliased subprograms. This code was wrong in
17777 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
17778 when the source is compiled with the No_Dispatching_Calls restriction.
17779 (Init_Predefined_Interface_Primitives): No need to inherit primitives
17780 if we are compiling with restriction No_Dispatching_Calls.
17781 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
17782 subprograms if we are compiling under No_Dispatching_Calls restriction.
17783 (Make_DT): Generate a dispatch table with a single dummy entry if
17784 we are compiling with the No_Dispatching_Calls restriction. In
17785 addition, in this case we don't generate code that calls to the
17786 following run-time subprograms: Set_Type_Kind, Inherit_DT.
17787 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
17788 of this subprogram if compiling with the No_Dispatching_Calls
17790 (Expand_Type_Conversion): Instead of using the actual parameter,
17791 the argument passed as parameter to the conversion function was
17792 erroneously referenced by the expander.
17793 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
17794 Set_Predefined_Primitive_Op_Address and Set_Signature.
17795 (Expand_Dispatching_Call): Generate call to
17796 Get_Predefined_Prim_Op_Address for predefined primitives.
17797 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
17798 predefined primitives.
17799 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
17800 primitives we reserve one dummy entry to ensure that the tag does not
17801 point to some memory that is associated with some other object. In
17802 addition, remove all the old code that generated the assignments
17803 associated with the signature of the dispatch table and replace them
17804 by a call to the new subprogram Set_Signature.
17805 (Set_All_DT_Position): Change the algorithm because now we have a
17806 separate dispatch table associated with predefined primitive operations.
17807 (Expand_Interface_Conversion): In case of non-static offset_to_top
17808 add explicit dereference to get access to the object after the call
17809 to displace the pointer to the object.
17810 (Expand_Interface_Thunk): Modify the generation of the actual used
17811 in the calls to the run-time function Offset_To_Top to fulfil its
17813 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
17815 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17817 * exp_dist.adb (Copy_Specification): For access parameters, copy
17818 Null_Exclusion flag, which will have been set for stream subprograms
17821 2006-02-13 Pascal Obry <obry@adacore.com>
17823 * expect.c (__gnat_expect_portable_execvp): New implementation. The
17824 previous implementation was using the C runtime spawnve routine but
17825 the corresponding wait was using directly the Win32 API. This was
17826 causing some times a lock when waiting for an event using
17827 WaitForSingleObject in __gnat_waitpid. This new implementation uses
17828 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
17829 API fixes this problem.
17831 2006-02-13 Robert Dewar <dewar@adacore.com>
17833 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

17841 array reference that is an explicit dereference, mark the converted
17842 (packed) array reference as analyzed to prevent a forthcoming
17843 reanalysis from resetting its type to the original (non-packed) array

17847 Javier Miranda <miranda@adacore.com>
17848 Eric Botcazou <ebotcazou@adacore.com>
17850 * exp_util.ads, exp_util.adb (Find_Prim_Op,
17851 Is_Predefined_Primitive_Operation): When
17852 searching for the predefined equality operator, verify that operands
17853 have the same type.
17854 (Is_Predefined_Dispatching_Operation): Remove the code that looks
17855 for the last entity in the list of aliased subprograms. This code
17856 was wrong in case of renamings.
17857 (Set_Renamed_Subprogram): New procedure
17858 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
17859 Exp_Type constant computed when entering this subprogram.

17861 (OK_To_Do_Constant_Replacement): New function
17862 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
17863 (Side_Effect_Free): An attribute reference 'Input is not free of
17864 side effect, unlike other attributes that are functions. (from code
17866 (Remove_Side_Effects): Expressions that involve packed arrays or records
17867 are copied at the point of reference, and therefore must be marked as
17868 renamings of objects.
17869 (Is_Predefined_Dispatching_Operation): Return false if the operation is
17870 not a dispatching operation.
17873 (Remove_Side_Effects): Lift enclosing type conversion nodes for
17874 elementary types in all cases.
17876 2006-02-13 Javier Miranda <miranda@adacore.com>
17878 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
17879 task types when accessing to the corresponding record type.
17880 Remove '!' in warning message.
17882 2006-02-13 Olivier Hainque <hainque@adacore.com>
17884 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
17885 to avoid useless and space inefficient overalignments on targets where
17886 Max_Alignment is larger than 16.
17888 2006-02-13 Pascal Obry <obry@adacore.com>
17890 * g-catiio.adb (Sec_Number): New type used to compute the number of
17891 seconds since 1-1-1970.
17892 (Image) [Natural]: The parameter was an Integer, as we can't deal with
17893 negative numbers (years, months...) it is better to have a Natural here.
17895 (Image) [Number]: Change parameter from Long_Integer to Number.
17896 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
17897 overflow for dates past year 2038.
17899 2006-02-13 Matthew Heaney <heaney@adacore.com>
17901 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
17904 2006-02-13 Arnaud Charlet <charlet@adacore.com>
17906 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
17908 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
17909 finalization can occur normally.
17911 2006-02-13 Vincent Celier <celier@adacore.com>
17913 * gnatcmd.adb (Rules_Switches): New table
17914 (Add_To_Rules_Switches): New procedure
17915 (GNATCmd): For command CHECK, put all options following "-rules" in the
17916 Rules_Switches table. Append these -rules switches after the -cargs
17919 2006-02-13 Robert Dewar <dewar@adacore.com>
17921 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
17922 These two cases were generating incorrect output, and if this unit
17923 was built with checks on, generated a discriminant mismatch constraint
17926 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17927 Robert Dewar <dewar@adacore.com>
17929 * lib-xref.adb (Get_Type_Reference): For a private type whose full
17930 view is an array type, indicate the component type as well, for
17931 navigation purposes.

17933 of violating pragma Unreferenced.
17934 Do not give Ada 2005 warning except on real reference.

17938 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
17939 main source, add switch -mdebug-main=_ada_ so that the executable can
17940 be debugged by the standard VMS debugger.
17941 (Gnatmake): Set No_Main_Subprogram to True when there is no main
17942 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
17943 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
17944 of the last source, as the binding and linking phases are never
17946 Set all executable obsolete when rebuilding a library.
17948 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
17951 2006-02-13 Javier Miranda <miranda@adacore.com>
17954 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
17955 code to improve the error message reported when the program has
17956 declarations of abstract interface types and it is not compiled with
17957 the -gnat05 switch.
17958 (P_Access_Definition): Reorganize the code to improve the error
17959 message reported when the new Ada 2005 syntax for anonymous
17960 access types is used and the program is not compiled with the

17976 * prj.adb (Reset): Initialize the first element of table Namings with
17977 the standard naming data.
17979 2006-02-13 Vincent Celier <celier@adacore.com>
17981 * prj.ads (Error_Warning): New enumeration type
17983 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
17984 unknown, use the location of the project to report the error.

18000 Prj.Nmsc.Check with parameter When_No_Sources.
18001 (Process): New parameter When_No_Sources. Call Check with parameter

18011 * prj-makr.adb (Make): Preserve the comments from the original project
18013 When removing nodes (attributes Source_Dirs, Source_Files,
18014 Source_List_File and package Naming), save the comments and attach the
18015 saved comments to the newly created nodes.
18016 Do not add a with clause for the naming package if one already exists.

18029 operation in the dispatch table if the source is compiled with
18030 restriction No_Dispatching_Calls.
18031 (Override_Dispatching_Operation): Check for illegal attempt to override
18032 No_Return procedure with procedure that is not No_Return
18033 (Check_Dispatching_Call): Suppress the check for an abstract operation
18034 when the original node of an actual is a tag-indeterminate attribute
18035 call, since the attribute, which must be 'Input, can never be abstract.
18036 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
18037 call to the Input attribute (even when rewritten).
18038 (Propagate_Tag): Augment comment to indicate the possibility of a call
18039 to an Input attribute.
18041 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
18042 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.

18055 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
18056 handles default-initialized components to keep separate the management
18057 of this feature but also avoid the unrequired resolution and
18058 expansion of components that do not have partially initialized
18060 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
18061 (Check_Bounds): Likewise.
18062 (Check_Length): Likewise.

18065 Ed Schonberg <schonberg@adacore.com>
18067 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
18068 abstract interface type call analyze_and_resolve to expand the type
18069 conversion into the corresponding displacement of the
18070 reference to the base of the object.
18071 (Eval_Attribute, case Width): For systems where IEEE extended precision
18072 is supported, the maximum exponent occupies 4 decimal digits.
18073 (Accessibility_Message): Add '\' in 2-line warning message.
18074 (Resolve_Attribute): Likewise.
18075 (case Attribute_Access): Significantly revise checks
18076 for illegal access-to-subprogram Access attributes to properly enforce
18077 the rules of 3.10.2(32/2).
18078 Diagnose use of current instance with an illegal attribute.
18080 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
18082 (Enclosing_Generic_Unit): New function to return a node's innermost
18083 enclosing generic declaration node.
18084 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
18085 (Type_Access_Level): The accessibility level of anonymous acccess types
18086 associated with discriminants is that of the current instance of the
18087 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
18088 (Compile_Time_Constraint_Error): Handle case of conditional expression.
18089 (Kill_Current_Values_For_Entity): New function
18090 (Enter_Name): Change formal type to Entity_Id
18092 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
18093 Ed Schonberg <schonberg@adacore.com>
18094 Gary Dismukes <dismukes@adacore.com>
18096 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
18097 Analyze_Compilation_Unit.
18098 Detect and warn on redundant with clauses detected in a package spec
18099 and/or body when -gnatwr is used.
18100 (Analyze_Context): Analyze config pragmas before other items
18101 (Install_Context_Items): Don't analyze config pragmas here
18102 (Install_Limited_Withed_Unit): Set limited entity of package in
18103 with_clause so that cross-reference information or warning messages on
18104 unused packages can be properly generated
18105 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
18106 has Error_Posted set. Prevent infinite loops in illegal programs.
18107 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
18108 to the point of the error test requiring the current unit to be private.
18109 This ensures that private with clauses are not exempted from the basic
18110 checking for being a descendant of the same library unit parent as a
18111 withed private descendant unit.
18112 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
18113 handle private with clauses properly, as well as to account for cases
18114 where the withed unit is a public descendant of a private ancestor
18115 (in which case the current unit must be a descendant of the private
18116 ancestor's parent). The spec comments were updated accordingly. Also,
18117 the old error message in this subprogram was replaced with error
18118 messages that mirror the errors tested and reported by
18119 Check_Private_Child_Unit.
18120 Parameter and variable names improved for readability.
18121 (Install_Limited_Context_Clauses): Remove test for a withed unit being
18122 private as the precondition for calling
18123 Check_Private_Limited_Withed_Unit since that subprogram has been
18124 revised to test public units as well as private units.

18128 Ed Schonberg <schonberg@adacore.com>
18129 Javier Miranda <miranda@adacore.com>
18131 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
18132 that Scope_Stack.First = 1.
18133 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18134 were not always properly handled previously.
18135 (Formal_Entity): Complete rewrite, to handle properly some complex case
18136 with multiple levels of parametrization by formal packages.
18137 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
18138 to the corresponding derived type declaration for proper semantics.
18140 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
18141 (Check_Component): Enforce restriction on components of
18142 unchecked_unions: a component in a variant cannot contain tasks or
18144 (Unchecked_Union): Allow nested variants and multiple discriminants, to
18146 Add pragma Ada_2005 (synonym for Ada_05)
18147 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18148 were not always properly handled previously.
18149 Document that pragma Propagate_Exceptions has no effect
18150 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
18151 (Set_Convention_From_Pragma): Check that if a convention is
18152 specified for a dispatching operation, then it must be
18153 consistent with the existing convention for the operation.
18154 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
18155 longer required to specify an vtable-ptr component in the record. For
18156 compatibility reasons we leave the support for the previous definition.
18157 (Analyze_Pragma, case No_Return): Allow multiple arguments
18159 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
18160 non-overrideen inherited operation with a controlling result as
18161 illegal only its implicit declaration comes from the derived type
18162 declaration of its result's type.
18163 (Check_Possible_Deferred_Completion): Relocate the object definition
18164 node of the subtype indication of a deferred constant completion rather
18165 than directly analyzing it. The analysis of the generated subtype will
18166 correctly decorate the GNAT tree.
18167 (Record_Type_Declaration): Check whether this is a declaration for a
18168 limited derived record before analyzing components.
18169 (Analyze_Component_Declaration): Diagnose record types not explicitly
18170 declared limited when a component has a limited type.
18171 (Build_Derived_Record_Type): Code reorganization to check if some of
18172 the inherited subprograms of a tagged type cover interface primitives.
18173 This check was missing in case of a full-type associated with a private
18175 (Constant_Redeclaration): Check that the subtypes of the partial and the
18176 full view of a constrained deferred constant statically match.
18177 (Mentions_T): A reference to the current type in an anonymous access
18178 component declaration must be an entity name.
18179 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
18180 class_wide type to refer to full type, not to the incomplete one.
18181 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
18182 available. Required to give support to the certified run-time.
18183 (Analyze_Component_Declaration): In case of anonymous access components
18184 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
18185 (Process_Discriminants): For an access discriminant, use the
18186 discriminant specification as the associated_node_for_itype, to
18187 simplify accessibility checks.
18189 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18190 Javier Miranda <miranda@adacore.com>
18192 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
18193 abstract interpretations on an operator, remove interpretations that
18194 yield Address or a type derived from it, if one of the operands is an
18196 (Try_Object_Operation.Try_Primitive_Operation,
18197 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
18198 location when creating the new reference to a primitive or class-wide
18199 operation as a part of rewriting a subprogram call.
18200 (Try_Primitive_Operations): If context requires a function, collect all
18201 interpretations after the first match, because there may be primitive
18202 operations of the same type with the same profile and different return
18203 types. From code reading.
18204 (Try_Primitive_Operation): Use the node kind to choose the proper
18205 operation when a function and a procedure have the same parameter
18207 (Complete_Object_Operation): If formal is an access parameter and prefix
18208 is an object, rewrite as an Access reference, to match signature of
18209 primitive operation.
18210 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
18211 by an expanded name with prefix Standard, when the operands are of an
18212 anonymous access type.
18213 (Remove_Abstract_Operations): If the operation is abstract because it is
18214 inherited by a user-defined type derived from Address, remove it as
18215 well from the set of candidate interpretations of an overloaded node.
18216 (Analyze_Membership_Op): Membership test not applicable to cpp-class
18219 2006-02-13 Bob Duff <duff@adacore.com>
18221 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
18222 redundant use clauses.
18223 In particular, if the scope of two use clauses overlaps, but one is not
18224 entirely included in the other, we should not warn. This can happen
18225 with nested packages.
18226 (Analyze_Subprogram_Renaming): Protect the compiler against previously
18227 reported errors. The bug was reported when the compiler was built
18228 with assertions enabled.
18229 (Find_Type): If the node is a 'Class reference and the prefix is a
18230 synchronized type without a corresponding record, return the type
18233 2006-02-13 Javier Miranda <miranda@adacore.com>
18235 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
18236 if this is the full-declaration associated with a private declaration
18237 that implement interfaces, then the private type declaration must be
18239 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
18240 as aliased. The use of the 'access attribute is not available for such
18241 object (for this purpose the object should be explicitly marked as
18242 aliased, but being an anonymous type this is not possible).
18244 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18245 Robert Dewar <dewar@adacore.com>
18247 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
18248 compilation unit is an elaboration scope.
18249 (Add_Task_Proc): Add '\' in 2-line warning message.
18250 (Activate_All_Desirable): Deal with case of unit with'ed by parent
18252 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18253 Javier Miranda <miranda@adacore.com>
18255 * sem_type.adb (Write_Overloads): Improve display of candidate
18257 (Add_One_Interp): Do not add to the list of interpretations aliased
18258 entities corresponding with an abstract interface type that is an
18259 immediate ancestor of a tagged type; otherwise we have a dummy
18260 conflict between this entity and the aliased entity.
18261 (Disambiguate): The predefined equality on universal_access is not
18262 usable if there is a user-defined equality with the proper signature,
18263 declared in the same declarative part as the designated type.
18264 (Find_Unique_Type): The universal_access equality operator defined under
18265 AI-230 does not cover pool specific access types.
18266 (Covers): If one of the types is a generic actual subtype, check whether
18267 it matches the partial view of the other type.
18269 2006-02-13 Thomas Quinot <quinot@adacore.com>
18271 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
18272 line. This is necessary to allow In_Extended_Main_Unit to provide
18273 correct results for itypes while writing out expanded source.
18274 (Close_File): No need to update the source_index_table here since it's
18275 now done for each line.
18277 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18278 Robert Dewar <dewar@adacore.com>
18280 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
18281 preserve the source unit where the itype is declared, and prevent a
18283 (Note_Implicit_Run_Time_Call): New procedure
18284 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
18287 * sprint.ads: Document use of $ for implicit run time routine call
18289 2006-02-13 Quentin Ochem <ochem@adacore.com>
18291 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
18294 2006-02-13 Bob Duff <duff@adacore.com>
18296 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
18297 Scan_Unsigned, so we do not scan leading blanks and sign twice.
18298 Integer'Value("- 5") and Integer'Value("-+5") now correctly
18299 raise Constraint_Error.
18301 * s-vallli.adb (Scan_Long_Long_Integer): Call
18302 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
18303 do not scan leading blanks and sign twice.
18304 Integer'Value("- 5") and Integer'Value("-+5") now correctly
18305 raise Constraint_Error.
18307 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
18308 Scan_Long_Long_Unsigned): Split out most of the processing from
18309 Scan_Long_Long_Unsigned out into
18310 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
18311 This prevents scanning leading blanks and sign twice.
18312 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
18315 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
18316 out most of the processing from Scan_Unsigned out into
18317 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
18318 This prevents scanning leading blanks and sign twice.
18320 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
18321 use with Modular'Value attribute.
18322 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
18325 2006-02-13 Robert Dewar <dewar@adacore.com>
18327 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value

18494 (Target_Object_Suffix): Initialize with target object suffix.
18496 * rident.ads: Add special exception to license.
18498 * targparm.adb (Get_Target_Parameters): Set the value of
18499 Multi_Unit_Index_Character after OpenVMS_On_Target gets its definitive
18501 (Get_Target_Parameters): Set OpenVMS_On_Target if openvms.

18522 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
18523 link to the version that does nothing. This way the task termination
18524 routine is not executed twice for the environment task when finishing
18525 because of an unhandled exception.

18536 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
18537 non-tasking version of the soft link for task termination. We do
18538 nothing since if we are using the non-tasking version it
18539 means that the task termination functionality is not used.
18540 (Null_Finalize_Global_List): Add this null version for the procedure
18541 in charge of finalizing the global list for controlled objects.
18542 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
18543 instead for handling run-time termination in a more flexible way.
18544 (Adafinal_NT): This new procedure will take care of finalizing the
18545 global list for controlled objects if needed, but no tasking
18548 * s-tarest.adb (Task_Lock): Do not try to lock again the
18549 Global_Task_Lock if we already own it. Otherwise, we get blocked in
18550 some run-time operations.
18551 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
18552 until all nested locks have been released.
18553 (Task_Wrapper): Call the fall-back task termination handler. It
18554 applies to all tasks but the environment task.

18561 moved to the Common_ATCB record.
18562 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
18563 Common_ATCB record.
18564 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the

18573 Ada.Task_Termination, for avoiding circular dependencies.
18574 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
18575 for storing task termination handlers. In addition,
18576 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
18577 Common_ATCB because it is used by both the regular and the restricted
18579 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
18580 Common_ATCB because it is used by both the regular and the restricted
18582 (Common_ATCB): Added a dynamic task analyzer field.

18590 using the soft links mechanism.
18591 (Task_Wrapper): added dynamic stack analysis.
18593 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
18594 potentially blocking operations has been moved from
18595 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
18596 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
18597 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
18598 this run-time check.
18600 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
18601 of task termination procedure.

18649 (Displace): New subprogram that displaces the pointer to the object
18650 to reference one of its secondary dispatch tables.
18651 (IW_Membership): Modified to use the new table of interfaces.
18652 (Inherit_TSD): Modified to use the new table of interfaces.

18670 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
18671 in all the calls to Expand_Interface_Thunk. Instead of referencing the
18672 record component containing the tag of the secondary dispatch table we
18673 have to use the Offset_To_Top run-time function to get this information;
18674 otherwise if the pointer to the base of the object has been displace
18675 we get a wrong value if we use the 'position attribute.
18677 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
18678 all the calls to Expand_Interface_Thunk.
18679 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

18682 ensure that the interfaces implemented by the ancestors are placed
18683 at the header of the generated list.
18684 (Expand_Interface_Conversion): Handle the case in which the displacement
18685 associated with the interface conversion is not statically known. In
18686 this case we generate a call to the new run-time subprogram Displace.

18713 RE_TK_Tagged, RE_TK_Task.
18715 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
18716 Init_Secondary_Tags_Internal to allow its use with interface types and
18717 also to generate the code for the new additional actual required
18718 by Set_Offset_To_Top.
18719 (Build_Init_Statements): In case of components associated with abstract
18720 interface types there is no need to generate a call to its IP.

18732 properly protected objects and attach handler in the case of the
18733 restricted profile.

18747 pointer initialization values. Make a SAVE_EXPR instead. Add comments
18748 about the use and expansion of SAVE_EXPRs in the various possible
18749 renaming handling cases.
18750 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
18751 abusing DECL_FCONTEXT.

18921 are implemented by the ancestors.
18922 (Derived_Type_Declaration): If the parent of the full-view is an
18923 interface perform a transformation of the tree to ensure that it has
18924 the same parent than the partial-view. This simplifies the job of the
18925 expander in order to generate the correct object layout, and it is
18926 needed because the list of interfaces of the full-view can be given in
18928 (Process_Full_View): The parent of the full-view does not need to be
18929 a descendant of the parent of the partial view if both parents are
18931 (Analyze_Private_Extension_Declaration): If declaration has an explicit
18932 "limited" the parent must be a limited type.

19009 attributes are visible at the point of the subprogram declaration.
19010 For Ada 2005, the error message is modified to indicate that the

19044 the implementation of Ada 2005 synchronized types because
19045 concurrent types were never tagged types in Ada 95.

19171 2005-11-21 Joel Sherrill <joel.sherrill@oarcorp.com>
19173 * socket.c: Add extern int h_errno for rtems since networking header
19174 files are not available at this point in a tool bootstrap. Newlib
19175 only has basic C library header files.

19269 TARGET, as it has the form of a math expression, and some components
19270 may be platform-defined macros.
19271 For VxWorks, generate the OK and ERROR values.
19272 New constants giving the sizes of the components of C struct timeval.

19284 deal with different cases of static and dynamic elaboration checks (all
19285 checks does not count in the first case, but does in the second).

19291 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
19292 elementary types using the operator in standard. It is cleaner not to
19293 modify the programmers intent, especially in the case of floating-point.
19294 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
19295 it did not matter because we always rewrote a/=b to not(a=b).
19296 (Expand_Allocator_Expression): For an allocator expression whose nominal
19297 subtype is an unconstrained packed type, convert the expression to its
19298 actual constrained subtype.
19299 Implement warning for <= or >= where < or > not possible
19300 Fix to Vax_Float tests (too early in many routines, causing premature
19301 Vax_Float expansions.
19303 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
19304 to be used with packages and generic packages as well as with

19307 of pragma Suppress (All_Checks)
19308 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
19309 a string literal for precise control over warnings.

19319 Allow optional = after -gnatm
19320 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
19321 longer sets Elaboration_Checks.
19322 Code to set warning mode moved to Sem_Warn
19323 so that it can be shared by pragma processing.
19325 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
19328 * s-taprop-solaris.adb:
19329 Change some <= to =, to avoid new warning

19335 2005-11-14 Robert Dewar <dewar@adacore.com>
19337 * exp_vfpt.adb: Handle /= case
19338 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
19339 so that we do not get duplicate scaling for fixed point conversions.
19341 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
19343 2005-11-14 Matthew Gingell <gingell@adacore.com>
19345 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
19346 Increase default priority on Lynx from 15 to 17, and meet the Ada
19347 requirement that Default_Priority be ((Priority'First +
19348 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

19440 Olivier Hainque <hainque@adacore.com>
19441 Eric Botcazou <ebotcazou@adacore.com>
19444 Factor common code to build a storage type for an unconstrained object
19445 from a fat or thin pointer type and a constrained object type.
19446 (annotate_value): Handle BIT_AND_EXPR.
19447 (annotate_rep): Don't restrict the back annotation of inherited
19448 components to the type_annotate_only case.
19449 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
19450 we are not defining the type.
19451 <E_Record_Type>: Likewise.
19452 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
19453 to get advantage of the new maybe_stabilize_reference interface, to
19454 ensure that what we reference is indeed stabilized instead of relying
19455 on assumptions on what the stabilizer does.
19456 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
19457 type imported through a limited_with clause, use its non-limited view.
19458 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
19460 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
19461 of #if sections + explicit comparisons of convention identifiers.
19462 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
19463 before early-returning for certain types when code generation is
19465 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
19466 nullification of gnu_expr we do for objects with address clause and
19467 that we are not defining.
19468 (elaborate_expression_1): Do not create constants when creating
19469 variables needed by the debug info: the dwarf2 writer considers that
19470 CONST_DECLs is used only to represent enumeration constants, and emits
19472 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
19473 object with an address clause into an indirect reference, drop the
19474 initializing expression.
19476 (STACK_CHECK_BUILTIN): Delete.

19484 related): For a prefix that is a dereference of a fat or thin pointer,
19485 if there is an actual subtype provided by the front-end, use that
19486 subtype to build an actual type with bounds template.
19487 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
19488 is provided by the front-end, use that subtype to compute the size of
19489 the deallocated object.
19490 (gnat_to_gnu): When adding a statement into an elaboration procedure,
19491 check for a potential violation of a No_Elaboration_Code restriction.
19492 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
19493 with extra arguments to control whether to recurse through non-values
19494 and to let the caller know if the stabilization has succeeded.
19495 (gnat_stabilize_reference): Now a simple wrapper around
19496 maybe_stabilize, for common uses without restriction on lvalues and
19497 without need to check for the success indication.
19498 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
19499 pass false instead of 0 as the FORCE argument which is a bool.
19500 (Identifier_to_gnu): Remove checks ensuring that an renamed object
19501 attached to a renaming pointer has been properly stabilized, as no such
19502 object is attached otherwise.
19503 (call_to_gnu): Invoke create_var_decl to create the temporary when the
19504 function uses the "target pointer" return mechanism.
19505 Reinstate conversion of the actual to the type of the formal
19506 parameter before any other specific treatment based on the passing
19507 mechanism. This turns out to be necessary in order for PLACEHOLDER
19508 substitution to work properly when the latter type is unconstrained.
19510 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
19512 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

19731 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
19732 'Terminated for task interface class-wide objects. Generate a call to
19733 the predefined dispatching routine used to retrieve the _task_id from

19763 the return value into its actual subtype in order to help the backend

19794 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

19814 attribute of the N_Free_Statement.
19815 Generate itype for classwide designated object in both cases of

20012 circular lists of Use_Clauses in a parent.
20013 (Implicit_With_On_Parent): Do add duplicate with_clause on parent when
20014 compiling body of child unit.
20015 Use new class N_Subprogram_Instantiation

20038 (Inline_Instance_Body): Deinstall and record the use_clauses for all
20039 parent scopes of a scope being removed prior to inlining an instance
20041 (Analyze_Package_Instantiation): Do not perform front-end inlining when
20042 the current context is itself an instance within a non-instance child
20043 unit, to prevent scope stack errors.
20044 (Save_References): If the node is an aggregate that is an actual in a
20045 call, rewrite as a qualified expression to preserve some type
20046 information, to resolve possible ambiguities in the instance.
20047 (Instance_Parent_Unit): New global variable to record the ultimate
20048 parent unit associated with a generic child unit instance (associated

20056 not already set. Replace test of Is_Child_Unit with test of parent's
20057 scope against package Standard. Add comments and a ??? comment.
20058 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible

20076 (Build_Private_Derived_Type): The entity of the created full view of the
20077 derived type does not come from source. If after installing the private

20079 full view to construct the full declaration of the derived type.
20080 (Build_Derived_Record_Type): Relax the condition that controls the
20081 execution of the check that verifies that the partial view and

20091 (Process_Full_View): Rename local subprogram Find_Interface_In_
20092 Descendant to Find_Ancestor_Interface to leave the code more clear.
20093 Remove wrong code that avoids the generation of an error message
20094 when the immediate ancestor of the partial view is an interface.
20095 In addition some minor reorganization of the code has been done to
20096 leave it more clear.
20097 (Analyze_Type_Declaration): If type has previous incomplete tagged
20098 partial view, inherit properly its primitive operations.
20099 (Collect_Interfaces): Make public, for analysis of formal

20112 be included in the interface list.
20113 (Access_Definition): If the designated type is an interface that may
20114 contain tasks, create Master_Id for it before analyzing the expression
20115 of the declaration, which may be an allocator.

20126 subprogram declaration.
20127 Change name Is_Package to Is_Package_Or_Generic_Package
20128 (Process_Formals): A non null qualifier on a non null named access
20129 type is not an error, and is a warning only if Redundant_Constructs

20140 package associated with a generic instance or formal package, the
20141 private declarations of the parent must be installed (by calling new

20143 Change name Is_Package to Is_Package_Or_Generic_Package
20144 (Preserve_Full_Attributes): For a synchronized type, the corresponding

20150 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
20151 not try to rewrite a renamed stream attribute, because the operations
20152 on the type may not have been generated.
20153 Handle properly a renaming_as_body generated for a stream operation
20154 whose default is abstract because the object type itself is abstract.
20155 (Find_Type): If the type is incomplete and appears as the prefix of a
20156 'Class reference, it is tagged, and its list of primitive operations
20157 must be initialized properly.
20158 (Chain_Use_Clauses): When chaining the use clauses that appear in the
20159 private declaration of a parent unit, prior to compiling the private
20160 part of a child unit, find on the scope stack the proper parent entity
20161 on which to link the use clause.
20162 (Note_Redundant_Use): Emit a warning when a redundant use clause is
20164 (Analyze_Object_Renaming): An attribute reference is not a legal object

20182 a procedure call is used as a select statement trigger and is not an
20183 entry renaming or a primitive of a limited interface.
20184 (Valid_Conversion): If the operand has a single interpretation do not
20185 remove address operations.
20186 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
20187 statement to inhibit warning.
20188 (Resolve_Unary_Op): Do not produce a warning when
20189 processing an expression of the form -(A mod B)
20190 Use Universal_Real instead of Long_Long_Float when we need a high
20191 precision float type for the generated code (prevents gratuitous
20192 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
20193 (Resolve_Concatenation_Arg): Improve error message when argument is an
20194 ambiguous call to a function that returns an array.
20195 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

21137 * checks.adb (Check_Needed): New procedure, deals with removing checks
21138 based on analysis of short-circuited forms. Also generates warnings for
21139 improper use of non-short-circuited forms.

21158 (Check_For_Source): Change value of Source_Id only after the current
21159 source has been dealt with.
21161 2005-09-01 Robert Dewar <dewar@adacore.com>
21162 Doug Rupp <rupp@adacore.com>
21164 * exp_attr.adb: Handle vax fpt for 'Valid attribute

21170 Hristian Kirtchev <kirtchev@adacore.com>
21171 Javier Miranda <miranda@adacore.com>
21173 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
21174 from object notation, the original node is unanalyzed and carries no
21175 semantic information, so that accessiblity checks must be performed on
21176 the type of the actual itself.
21177 (Expand_N_Subprogram_Declaration): Change last actual parameter for
21178 compatibility with Build_Protected_Sub_Specification.
21179 (Check_Overriding_Inherited_Interfaces): Add suport to handle
21180 overloaded primitives.
21181 (Register_Interface_DT_Entry): Use the new name of the formal
21182 the the calls to Expand_Interface_Thunk
21184 * exp_dbug.ads: Augment comments on encoding of protected types to
21185 include the generation of dispatching subprograms when the type
21186 implements at least one interface.
21188 * lib.ads: Extend information in Load_Stack to include whether a given
21189 load comes from a Limited_With_Clause.
21191 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
21192 whether a potential circularity is harmless, because it includes units
21193 loaded through a limited_with clause. Extends previous treatment which
21194 did not handle properly arbitrary combinations of limited and
21195 non-limited clauses.
21197 2005-09-01 Nicolas Setton <setton@adacore.com>
21199 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
21200 to be encoded as typ___XBLU_lowerbound__upperbound instead of
21201 typ___XB_lowerbound__upperbound.
21203 2005-09-01 Thomas Quinot <quinot@adacore.com>
21205 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
21206 dummy access formal for RACW/RAS TypeCode TSS.
21207 (Build_TypeCode_Call): Do not generate dummy null access actual for
21208 calls to the TypeCode TSS.
21210 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21212 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
21213 fully qualified name, to distinguish instances with the same local name.
21215 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
21218 2005-09-01 Robert Dewar <dewar@adacore.com>

21227 (Close): Deallocate any existing filter for the concerned connection
21229 2005-09-01 Laurent Pautet <pautet@adacore.com>
21231 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
21232 position set is provided, we compute one in order to reduce the maximum
21233 length of the keys. This computation first selects a character
21234 position between 1 and the minimum length of the keys in order to
21235 avoid reducing one of the keys to an empty string.
21236 (Initialize, Compute): When the ratio V to K is too low, the algorithm
21237 does not converge. The initialization procedure now comes with a
21238 maximum number of iterations such that when exceeded, an exception is
21239 raised in Compute. The user can initialize this ratio to another value
21241 Reformating and updated headers.
21243 2005-09-01 Javier Miranda <miranda@adacore.com>
21245 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
21246 that given an entity T creates and returns an Itype that duplicates the
21247 contents of T. The returned Itype has the null-exclusion
21248 attribute set to True, and its Etype attribute references T
21249 to keep the association between the two entities.
21250 Update copyright notice
21252 * sem_aggr.adb (Check_Can_Never_Be_Null,
21253 Aggregate_Constraint_Checks, Resolve_Aggregate,
21254 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
21256 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

21259 Robert Dewar <dewar@adacore.com>
21260 Hristian Kirtchev <kirtchev@adacore.com>

21268 (P_Subprogram_Specification): Add parsing of anonymous access result
21269 plus null exclusions. Call Set_Result_Definition instead of
21272 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
21273 (P_Access_Type_Definition): Add parsing for an anonymous access result
21274 subtype, plus parsing for null exclusions. Call Set_Result_Definition
21275 instead of Set_Subtype_Mark.
21277 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
21278 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
21279 (Result_Definition): New function for N_Function_Specifications.
21280 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
21281 N_Function_Specification.
21282 (Set_Null_Exclusion_Present): Allow this flag for
21283 N_Function_Specification.
21284 (Set_Result_Definition): New procedure for N_Function_Specifications.
21285 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
21286 and N_Function_Specification.
21288 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
21289 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
21290 Add support for LIMITED NEW for Ada 2005 AI-419
21291 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
21292 syntax for anonymous access results.
21293 Replace Subtype_Mark field by Result_Definition in
21294 N_Function_Specification and N_Access_Definition specs.
21295 Add Null_Exclusion_Present to spec of N_Function_Specification.
21296 (Result_Definition): New function for N_Function_Specification and
21297 N_Access_Function_Definition.
21298 (Set_Result_Definition): New procedure for N_Function_Specification and
21299 N_Access_Function_Definition.
21301 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
21302 Result_Definition for cases of N_Access_Function_Definition and
21303 N_Function_Specification.
21304 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
21306 2005-09-01 Vincent Celier <celier@adacore.com>
21308 * lib-writ.adb: Update Copyright notice
21309 (Write_With_Lines): On platforms where file names are case-insensitive,
21310 record the file names in lower case.
21311 (Write_ALI): For D lines, on platforms where file names are
21312 case-insensitive, record the file names in lower case.
21314 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21315 Emmanuel Briot <briot@adacore.com>
21317 * lib-xref.adb (Output_Overridden_Op): Display information on
21318 overridden operation.

21326 overriding entity information.
21328 2005-09-01 Vincent Celier <celier@adacore.com>
21330 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
21331 including those that are inherited.
21333 2005-09-01 Robert Dewar <dewar@adacore.com>
21335 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
21337 * par-prag.adb: Implement new pragma Debug_Policy
21339 * sem_prag.adb Implement new pragma Debug_Policy
21340 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
21341 Component_Size attribute specification. Give warning for ignored pragma
21344 * snames.h, snames.ads, snames.adb: Introduce entries in
21345 Preset_Names for Name_Disp_Asynchronous_Select,
21346 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
21347 Name_Disp_Timed_Select.
21348 New pragma Debug_Policy
21350 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
21352 Switch -gnata also sets Debug_Pragmas_Enabled
21354 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
21355 handle an explicit -gnata when compiling predefined files.
21357 2005-09-01 Vincent Celier <celier@adacore.com>
21359 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
21360 directories of projects that have no Ada sources.
21362 2005-09-01 Robert Dewar <dewar@adacore.com>
21364 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
21365 (makes a difference for wide characters)
21367 * widechar.adb, widechar.ads:
21368 Add Wide_Char_Byte_Count feature to count chars vs bytes
21370 2005-09-01 Thomas Quinot <quinot@adacore.com>
21371 Ed Schonberg <schonberg@adacore.com>
21372 Robert Dewar <dewar@adacore.com>
21374 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
21375 'Address attribute reference with an overloaded prefix, use the
21376 location of the prefix (not the location of the attribute reference) as
21377 the error location.
21378 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
21379 a function renaming thereof, is a valid prefix for 'Size (where it is
21380 intepreted as a function call).
21381 (Statically_Denotes_Entity): New predicate to determine whether the
21382 prefix of an array attribute can be considered static.
21385 (Eval_Attr): Fix failure to evaluate Component_Size for
21386 unconstrained arrays (resulted in wrong value in packed case, since
21387 back end cannot handle this case)
21389 2005-09-01 Robert Dewar <dewar@adacore.com>
21391 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
21392 error msgs for most common cases.
21393 Use new errout insertion char < (conditional warning)
21395 2005-09-01 Javier Miranda <miranda@adacore.com>
21396 Ed Schonberg <schonberg@adacore.com>
21398 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
21399 become local to the whole package.
21400 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
21401 the package was already analyzed the new algorithm "replaces" the
21402 real entities by the shadow ones. This is required to ensure that
21403 the order of these entities in the homonym chains does not change;
21404 otherwise we can have undefined references at linking time because
21405 in case of conflicts the external name of the entities will have
21406 a suffix that depends on the order of the entities in the chain.
21407 (Remove_Limited_With_Clause): Complementary code that completes the
21408 new algorithm and replaces the shadow entities by the real ones.
21409 (Install_Limited_Withed_Unit): When unchaining entities before the
21410 installation of the shadow entities, only regular entities of the
21411 public part must be taken into account. This is required to
21412 keep this routine in synch with the work done by Remove_Limited_
21414 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
21415 even if unit is analyzed, because the analysis of the unit is
21416 idempotent in any case, and the limited view of the unit may have to
21417 be installed for proper visibility.
21418 (Expand_Limited_With_Clause): Even if the unit in the implicit
21419 with_clause has been analyzed already, a limited view of the package
21420 must be built for the current context, if it does not exist yet.
21422 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21423 Javier Miranda <miranda@adacore.com>
21424 Gary Dismukes <dismukes@adacore.com>
21426 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
21427 defining entity for the instance body, make a new defining identifier
21428 rather than copying the entity of the spec, to prevent accidental
21429 sharing of the entity list.
21430 (Check_Private_View): When exchanging views of private types, build the
21431 list of exchanged views as a stack, to ensure that on exit the exchanges
21432 are undone in the proper order.
21433 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
21434 Restore the compilation environment in case of instantiation_error.
21435 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
21436 for an anonymous access result.
21437 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
21438 (Formal_Entity): Handle properly the case of a formal package that
21439 denotes a generic package renaming.
21441 2005-09-01 Thomas Quinot <quinot@adacore.com>
21443 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
21444 clause if the array aggregate is surrounded by parentheses.
21446 2005-09-01 Cyrille Comar <comar@adacore.com>
21447 Gary Dismukes <dismukes@adacore.com>
21448 Ed Schonberg <schonberg@adacore.com>
21449 Javier Miranda <miranda@adacore.com>
21451 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
21453 to check if a type is Constrained in cases related to code generation
21454 (rather than semantic checking) since otherwise we do not generate
21455 similar code for mutable private types depending if their
21456 discriminants are visible or not.
21457 (Check_Abstract_Overriding): Do not complain about failure to override
21458 the primitive operations used in dispatching selects since they will
21459 always be overriden at the freeze point of the type.
21460 (Access_Definition): Separate out handling for resetting the scope
21461 of an anonymous access function result type. Retrieve the scope
21462 of the associated function rather than using Current_Scope, which
21463 does not have a consistent value (depends on whether we're in the
21464 middle of analyzing formal parameters). Add ??? comment about
21465 finding a cleaner way to handle the special cases of scope setting.
21466 (Process_Incomplete_Dependents): A protected operation is never a
21467 dispatching operation (only its wrapper may be).
21468 (Build_Derived_Record_Type): In case of tagged private types that
21469 implement interfaces add derivation of predefined primitive
21471 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
21472 by two parameters that are used in case of derivation from abstract
21473 interface types: No_Predefined_Prims is used to avoid the derivation
21474 of predefined primitives from the interface, and Predefined
21475 Prims_Only is used to complete the derivation predefined primitives
21476 in case of private tagged types implementing interfaces.
21477 Fix typo in comments
21478 (Find_Interface_In_Descendant): Protect the frontend against
21479 wrong code with large circularity chains.
21480 (Is_Private_Overriding): Add support for entities overriding interface
21481 subprograms. The test failed because Entities associated with overriden
21482 interface subprograms are always marked as hidden (and used to build
21483 the secondary dispatch table); in this case the overriden entity is
21484 available through the field abstract_interface_alias (cf. override_
21485 dispatching_operation)
21486 (Access_Definition): Set the scope of the type to Current_Scope for the
21487 case of a function with an anonymous access result type.
21488 (Access_Subprogram_Declaration): Handle creation of the type entity for
21489 an access-to-function type with an anonymous access result.
21490 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
21491 in handling for N_Access_Function_Definition.
21492 (Analyze_Subtype_Declaration): Modify the text of error message.
21493 (Derived_Type_Declaration): Modify the text of error message.
21494 (Process_Subtype): Modify the text of error message plus cleanup
21495 of one redundant error message.
21496 (Analyze_Component_Declaration): Code cleanup.
21497 (Analyze_Object_Declaration): Code cleanup.
21498 (Analyze_Subtype_Declaration): Propagate the null-exclusion
21499 attribute in case of access types. Code cleanup.
21500 (Array_Type_Declaration): Code cleanup.
21501 (Process_Discriminants): Create the new null-excluding itype
21502 if required. Code cleanup.
21503 (Process_Subtype): Create the new null-excluding itype if
21504 required. Code cleanup.
21505 (Build_Derived_Record_Type): Code cleanup to avoid calling
21506 twice the subprogram derive_subprograms in case of private
21507 types that implement interfaces. In this particular case the
21508 subprogram Complete_Subprograms_Derivation already does the
21509 job associated with the second call.
21511 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
21512 conversion to the full view when generating an operation for a
21513 discriminant whose type may currently be private.
21515 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21516 Javier Miranda <miranda@adacore.com>
21518 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
21519 V (Obj.F), the rewriting does not involve the indexed component, but
21520 only the selected component itself.
21521 Do not apply the transformation if the analyzed node is an actual of a
21522 call to another subprogram.
21523 (Complete_Object_Operation): Retain the entity of the
21524 dispatching operation in the selector of the rewritten node. The
21525 entity will be used in the expansion of dispatching selects.
21526 (Analyze_One_Call): Improve location of the error message associated
21528 (Analyze_Selected_Component): No need to resolve prefix when it is a
21529 function call, resolution is done when parent node is resolved, as
21531 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
21532 when attempting to resolve a call transformed from its object notation.
21533 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
21534 of the argument list for each interpretation of the operation.
21535 (Try_Object_Operation): The designated type of an access parameter may
21536 be an incomplete type obtained through a limited_with clause, in which
21537 case the primitive operations of the type are retrieved from its full
21539 (Analyze_Call): If this is an indirect call, and the return type of the
21540 access_to_subprogram is incomplete, use its full view if available.
21542 2005-09-01 Javier Miranda <miranda@adacore.com>
21543 Gary Dismukes <dismukes@adacore.com>
21545 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
21546 access types the null-exclusion and access-to-constant attributes must
21548 (Analyze_Return_Statement): When the result type is an anonymous access
21549 type, apply a conversion of the return expression to the access type
21550 to ensure that appropriate accessibility checks are performed.
21551 (Analyze_Return_Type): For the case of an anonymous access result type,
21552 generate the Itype and set Is_Local_Anonymous_Access on the type.
21553 Add ??? placeholder for check to disallow returning a limited object
21554 in Ada 2005 unless it's an aggregate or a result of a function call.
21555 Change calls from Subtype_Mark to Result_Definition.
21556 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
21557 Result_Definition in call to Make_Function_Specification.
21558 (Build_Body_To_Inline): Change Set_Subtype_Mark to
21559 Set_Result_Definition.
21560 (Make_Inequality_Operator): Change formal Subtype_Mark to
21561 Result_Definition in call to Make_Function_Specification.
21562 (Process_Formals): Create the new null-excluding itype if required.
21563 (New_Overloaded_Entity): For an entity overriding an interface primitive
21564 check if the entity also covers other abstract subprograms in the same
21565 scope. This is required to handle the general case, that is, overriding
21566 other interface primitives and overriding abstract subprograms inherited
21567 from some abstract ancestor type.
21568 (New_Overloaded_Entity): For an overriding entity that comes from
21569 source, note the operation that it overrides.
21570 (Check_Conformance, Type_Conformant): Addition of one new formal
21571 to skip controlling formals in the analysis. This is used to
21572 handle overloading of abstract interfaces.
21573 (Base_Types_Match): Add missing case for types imported from
21574 limited-with clauses
21575 (New_Overloaded_Entity): Add barrier to protect the use of
21576 the "alias" attribute.
21578 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21580 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
21581 verify that the procedure and the entry are mode conformant.
21582 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
21583 as a different operator, which is often a cut-and-paste error.
21585 2005-09-01 Javier Miranda <miranda@adacore.com>
21586 Ed Schonberg <schonberg@adacore.com>
21588 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
21589 used in controlling parameters exclude null because it is necessary to
21590 read the tag to dispatch, and null has no tag.
21591 (Override_Dispatching_Operation): If the previous operation is inherited
21592 from an interface, it becomes hidden and does not participate in later

21596 Ed Schonberg <schonberg@adacore.com>
21597 Gary Dismukes <dismukes@adacore.com>
21599 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
21600 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
21601 the expander will generate the corresponding run-time check to evaluate
21603 (Resolve_Call): Check for legal type of procedure name or prefix that
21604 appears as a trigger in a triggering alternative.
21605 (Valid_Conversion): If expression is ambiguous and the context involves
21606 an extension of System, remove System.Address interpretations.
21607 (Resolve_Qualified_Expression): Reject the case of a specific-type
21608 qualification applied to a class-wide argument. Enhance comment
21609 to explain checking of Original_Node.
21610 (Resolve_Type_Conversion): The location of the error message was not
21611 general enough to handle the general case and hence it has been removed.
21612 In addition, this patch improves the text of the message.
21613 (Resolve_Type_Conversion): Add missing support for access to interface
21615 (Resolve_Type_Conversion): If the target is a class-wide interface type,
21616 do not expand if the expression is the actual in a call, because proper
21617 expansion will take place when the call itself is expanded.
21618 (Resolve_Allocator): If the context is an unchecked conversion, the
21619 allocator inherits its storage pool, if any, from the target type of

21623 Javier Miranda <miranda@adacore.com>
21625 * sem_type.adb (Add_One_Interp): If a candidate operation is an
21626 inherited interface operation that has an implementation, use the
21627 implementation to avoid spurious ambiguities.
21628 (Interface_Present_In_Ancestor): In case of concurrent types we can't
21629 use the Corresponding_Record_Typ attribute to look for the interface
21630 because it is set by the expander (and hence it is not always
21631 available). For this reason we traverse the list of interfaces
21632 (available in the parent of the concurrent type).
21633 (Interface_Present_In_Ancestor): Handle entities from the limited view
21635 2005-09-01 Ed Schonberg <schonberg@adacore.com>

21640 primitive procedure of a limited interface with a controlling first
21642 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
21644 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
21645 capture if it is generated in the second operand of a short-circuit
21647 Do not capture values for variables with address clauses.
21648 (Is_Object_Reference): Treat a function call as an object reference only
21649 if its type is not Standard_Void_Type.
21651 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21653 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
21654 to a variable that is statically known to be constant.

22436 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
22437 longer protected objects. They have been replaced by lower-level
22438 suspension objects made up by a mutex and a condition variable (or
22439 their equivalent given a particular OS) plus some internal data to
22440 reflect the state of the suspension object.
22441 (Initialize, Finalize): Add this initialization procedure for
22442 Suspension_Object, which is a controlled type.
22443 (Finalize): Add the finalization procedure for Suspension_Object,
22444 which is a controlled type.
22446 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

22469 object to True, releasing the task that was suspended, if any.
22470 (Suspend_Until_True): Add this procedure that blocks the calling task
22471 until the state of the object is True. Program_Error is raised if
22472 another task is already waiting on that suspension object.
22473 (Initialize): Add this procedure for initializing the suspension
22474 object. It initializes the mutex and the condition variable which are
22475 used for synchronization and queuing, and it sets the internal state
22477 (Finalize): Add this procedure for finalizing the suspension object,
22478 destroying the mutex and the condition variable.

22484 which provides a low-level abstraction (using operating system
22485 primitives) for Ada.Synchronous_Task_Control.
22486 This object is made up by a mutex (for ensuring mutual exclusion), a
22487 condition variable (for queuing threads until the condition is
22488 signaled), a Boolean (State) indicating whether the object is open,
22489 and a Boolean (Waiting) reflecting whether there is a task already

22745 declaration, create anonymous access types for each self-referential
22747 (Analyze_Component_Declaration, Array_Type_Declaration): Indicate that
22748 an access component in this context is a Local_Anonymous_Access, for
22749 proper accessibility checks.

22897 subprogram_specification that returns true if some non
22898 class-wide interface subprogram is found

22903 (Is_Unchecked_Conversion): Improve the test that recognizes
22904 instantiations of Unchecked_Conversion, and allows them in bodies that
22905 are to be inlined by the front-end. When the body comes from an

22928 object or component (that is, when Is_Local_Anonymous_Access is true).
22929 Prevent the special checks for conversions of access discriminants in
22930 the case where the discriminant belongs to a nonlimited type, since
22931 such discriminants have their accessibility level defined in the same
22932 way as a normal component of an anonymous access type.
22933 (Resolve_Allocator): When an allocator's designated type is a class-wide
22934 type, check that the accessibility level of type given in the

22955 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
22956 check on possible violation of restriction No_Direct_Boolean_Operators
22957 until after expansion of operands, to prevent spurious errors when

23260 the "simple_choice" member in a variant record, in accordance with the
23261 description in the package spec: the information output for a constant
23262 should be "S number", not "SS number".
23263 (Get_Encoded_Name): Return at once if not generating code. Avoids name

23329 of the type is declared in a record (for determination of insertion
23331 (SO_Ref_From_Expr): Test whether Vtype denotes a partial or full view of

23351 unit as a consequence of parsing a limited-with clause. This is used
23352 to avoid the circularity check.

23355 (Analyze_Context): Limited-with clauses are now allowed
23356 in more compilation units.

23358 againts previously reported critical errors in context clauses
23359 (Install_Limited_Withed_Unit): Code cleanup plus static detection
23360 of two further errors: renamed subprograms and renamed packages

23380 (Get_Type_Reference): For a subtype that is the renaming of an actual in
23381 an instantiation, use the first_subtype to ensure that we don't generate

23914 (check dos line terminator).
23915 (Check_Line_Max_Length): New procedure, split off from the existing
23916 Check_Line_Terminator routine. Separating this out allows -gnatyf to
23917 be properly recognized.
23919 * styleg.adb: Add ??? comment for line terminator reference

23962 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
23963 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
23964 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
23965 analyzed if expansion is disabled (which could otherwise cause spurious
23966 error messages if expansion has been disabled due to previous
23967 (unrelated) errors).
23969 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
23970 is disabled, the entity denoted by the argument is the access type
23971 itself, not an underlying record type, so there is no need to go back
23972 to the Corresponding_Remote_Type.
23974 2005-03-29 Gary Dismukes <dismukes@adacore.com>
23975 Robert Dewar <dewar@adacore.com>

23978 expand a call to an instance of
23979 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
23980 Constructor actual of the instance. A class-wide membership
23981 check is also generated, to ensure that the tag passed to the instance
23982 denotes a type in the class.
23983 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
23984 of Name_Generic_Dispatching_Constructor.
23986 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
23987 05 unit for AI-260-02).

24001 the case of renaming of stream attributes when the renaming denotes a
24002 generic formal subprogram association for an abstract formal subprogram.
24003 Check that the attribute is a primitive stream attribute (and not
24004 a class-wide stream attribute) and then rewrite the attribute name
24005 as the name of the appropriate compiler-generated stream primitive.
24007 2005-03-29 Robert Dewar <dewar@adacore.com>
24009 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

24016 * freeze.adb (Freeze_Record_Type): If the type of the component is an
24017 itype whose parent is controlled and not yet frozen, do not create a
24018 freeze node for the itype if expansion is disabled.
24020 2005-03-29 Vincent Celier <celier@adacore.com>
24022 * make.adb (Gnatmake): Don't fail if the main project file is declared
24023 as having no Ada sources. Do not display message "no sources to
24024 compile" in quiet output.
24026 2005-03-29 Doug Rupp <rupp@adacore.com>
24028 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

24039 missing TYPE Improve the error message generated when compiling a
24040 limited interface in Ada83 or Ada95 mode.
24042 2005-03-29 Robert Dewar <dewar@adacore.com>
24044 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
24045 rather than proceed ahead using a junk attribute name.
24047 2005-03-29 Vincent Celier <celier@adacore.com>
24049 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
24051 * prj-part.adb (Parse_Single_Project): Set the location of a project
24052 on its defining identifier, rather than on the reserved word "project".
24054 * prj-proc.adb (Expression): Adapt to the fact that default of external
24055 references may be string expressions, not always literal strings.
24056 (Recursive_Process): Set Display_Name equal to Name
24057 when Location is No_Location, that is when there is no actual file.
24058 Get the Display_Name of the project from the source, when it is not a
24060 (Process): Use the Display_Name in error messages
24062 * prj-strt.adb (External_Reference): Allow default to be string
24063 expressions, not only literal strings.
24065 2005-03-29 Vincent Celier <celier@adacore.com>
24067 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
24068 file and the reference symbol file to be the same file.
24070 2005-03-29 Thomas Quinot <quinot@adacore.com>
24072 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
24073 forbid conversion of a local access-to-subprogram type to a remote one.
24075 * sem_util.adb (Wrong_Type): For a record type that is the expanded
24076 equivalent type for a remote access-to-subprogram type, go back to the
24077 original RAS entity when displaying an error message, so the casing is
24078 the original source casing.
24080 2005-03-29 Robert Dewar <dewar@adacore.com>
24082 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
24085 2005-03-29 Ed Schonberg <schonberg@adacore.com>
24087 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
24088 subtype if code is being pre-analyzed, to prevent un-expanded
24089 references to protected formals, among others.
24090 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
24091 interpretation that can be a call, include the result of the call as a
24092 possible interpretation of the dereference.
24094 * sem_ch5.adb (Process_Bounds): Determine type of range by
24095 pre-analyzing a copy of the original range, and then analyze the range
24096 with the expected type.
24098 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
24099 with an overloaded prefix where not all interpretations yield an
24100 access to subprogram, do not rewrite node as a call.
24101 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
24102 the node as a call once the context identifies the interpretation of
24103 the prefix whose call yields the context type.
24104 (Valid_Conversion): For the case of a conversion between
24105 local access-to-subprogram types, check subtype conformance using
24106 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
24107 detailed error message.
24109 2005-03-29 Ed Schonberg <schonberg@adacore.com>
24111 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
24112 indicator, indicate that the formal can never be null.
24113 (Process_Formals): If a formal has a non_null indicator, insert the
24114 resulting subtype immediately before the enclosing subprogram decl,
24115 and not at the beginning of the corresponding declarative part, to
24116 prevent access before elaboration (Ada2005).
24118 2005-03-29 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

24664 2005-03-15 Robert Dewar <dewar@adacore.com>
24666 * a-stzunb.adb, a-stzunb.adb a-stzunb.ads, a-stzunb.ads,
24667 a-stwiun.ads, a-stwiun.adb, a-strunb.ads, a-strunb.adb: Move
24668 Realloc_For_Chunk to private part of package.
24669 New subprograms for AI-301
24671 * a-szuzti.adb, a-suteio.adb, a-swuwti.adb: Improve efficiency of
24672 Get_Line procedure.
24673 Avoid unnecessary use of Get/Set_Wide_String
24675 2005-03-15 Robert Dewar <dewar@adacore.com>
24678 * a-stunau.ads, a-stunau.adb:
24679 Change interface to allow efficient (and correct) implementation
24680 The previous changes to allow extra space in unbounded strings had
24681 left this interface a bit broken.
24683 * a-suteio.adb: Avoid unnecessary use of Get/Set_String
24685 * g-spipat.ads, g-spipat.adb: New interface for Get_String
24686 Minor reformatting (function specs)
24688 * g-spitbo.adb: New interface for Get_String
24690 * g-spitbo.ads: Minor reformatting
24692 * a-swunau.ads, a-swunau.adb: New interface for Get_Wide_String
24694 * a-szunau.ads, a-szunau.adb: New interface for Get_Wide_Wide_String
24696 2005-03-15 Javier Miranda <miranda@adacore.com>
24697 Robert Dewar <dewar@adacore.com>
24698 Thomas Quinot <quinot@adacore.com>
24699 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24701 * atree.ads, atree.adb: Add support for Elist24 field
24703 * atree.h: Fix wrong definition of Field27
24704 Add support for Elist16 field
24705 Add support for Elist24 field
24707 * einfo.ads, einfo.adb (Abstract_Interfaces,
24708 Set_Abstract_Interfaces): New subprograms.
24709 (Abstract_Interface_Alias, Set_Abstract_Interface_Alias): New
24711 (Access_Disp_Table, Set_Access_Disp_Table): Modified to handle a list of
24712 entities rather than a single node.

24720 (Set_Task_Body_Procedure): New subprogram to set this attribute.
24721 (Has_Controlled_Component): Now applies to all entities.
24722 This is only a documentation change, since it always worked to apply
24723 this to other than composite types (yielding false), but now this is
24725 Update documentation on Must_Be_Byte_Aligned for new spec
24727 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
24728 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
24729 uses of the Access_Disp_Table attribute to reference the first dispatch
24730 table associated with a tagged type. As
24731 part of the implementation of abstract interface types,
24732 Access_Disp_Table has been redefined to contain a list of dispatch
24733 tables (rather than a single dispatch table).
24734 Similarly, upgrade all the references to Tag_Component by the
24735 new attribute First_Tag_Component.
24736 (Find_Inherited_TSS): Moved to exp_tss.
24737 Clean up test in Expand_N_Object_Declaration for cases
24738 where we need to do a separate assignment of the initial value.
24739 (Expand_N_Object_Declaration): If the expression in the
24740 declaration of a tagged type is an aggregate, no need to generate an
24741 additional tag assignment.
24742 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
24744 Bit packed array ops are only called if operands are known to be
24746 (Component_Equality): When returning an N_Raise_Program_Error statement,
24747 ensure that its Etype is set to Empty to avoid confusing GIGI (which
24748 expects that only expressions have a bona fide type).
24749 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
24750 determine the amount of data to be copied.
24752 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
24753 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
24754 INTERFACE_TYPE_DEFINITION ::=
24755 [limited | task | protected | synchronized] interface
24756 [AND interface_list]
24758 * par-ch3.adb (P_Type_Declaration): Modified to give support to
24760 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
24762 (P_Interface_Type_Definition): New subprogram that parses the new
24763 syntax rule of Ada 2005 interfaces
24764 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
24765 messages by the correct RENAMES (quotes removed).
24767 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
24768 attribute First_Tag_Component.
24770 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
24771 (Interface_List, Set_Interface_List): New subprograms.
24772 (Interface_Present, Set_Interface_Present): New subprograms.
24773 (Limited_Present, Set_Limited_Present): Available also in derived
24774 type definition nodes.
24775 (Protected_Present, Set_Protected_Present): Available also in
24776 record type definition and
24777 derived type definition nodes.
24778 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
24779 (Task_Present, Set_Task_Present): New subprogram.
24780 (Task_Body_Procedure): Removed.
24781 (Set_Task_Body_Procedure): Removed.
24782 These subprogram have been removed because the attribute
24783 Task_Body_Procedure has been moved to the corresponding task type
24784 or task subtype entity to leave a field free to store the list
24785 of interfaces implemented by a task (for AI-345)
24786 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
24787 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
24788 expression flag Do_Range_Check
24789 (Exception_Junk): Change to Flag7 to accomodate above change
24790 (Box_Present, Default_Name, Specification, Set_Box_Present,
24791 Set_Default_Name, Set_Specification): Expand the expression
24792 "X in N_Formal_Subprogram_Declaration" into the corresponding
24793 two comparisons. Required to use the csinfo tool.
24795 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
24796 "with string" given.
24798 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
24801 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
24804 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
24805 attribute Task_Body_Procedure rather than the old semantic field that
24806 was available in the task_type_declaration node.
24808 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
24809 interface type definitions.
24810 (P_Formal_Derived_Type_Definition): Modified to handle the list of
24813 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
24814 task type declaration.
24815 (P_Protected): Modified to handle the list of interfaces in a
24816 protected type declaration.
24818 2005-03-15 Doug Rupp <rupp@adacore.com>
24819 Vincent Celier <celier@adacore.com>
24821 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
24822 (Gen_Output_File_C): Likewise.
24823 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
24825 2005-03-15 Thomas Quinot <quinot@adacore.com>
24827 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
24828 is an N_Raise_Constraint_Error node, create a new copy of it without
24829 going through a call to Duplicate_Subexpr.
24831 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
24832 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24833 Nicolas Setton <setton@adacore.com>
24834 Ed Schonberg <schonberg@adacore.com>
24840 * decl.c (gnat_to_gnu_field): Reject aliased components with a
24841 representation clause that prescribes a size not equal to the rounded
24842 size of their types.
24843 (gnat_to_gnu_entity, case E_Component): Always look at
24844 Original_Record_Component if Present and not the entity.
24845 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
24846 of tagged extension types by not making field for components that are
24848 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
24849 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
24850 expression to the type of the object when the object is constant.
24851 Reverse defer_debug_incomplete_list before traversing it, so that trees
24852 are processed in the order at which they were added to the list. This
24853 order is important when using the stabs debug format.
24854 If we are deferring the output of debug information, also defer this
24855 output for a function return type.
24856 When adding fields to a record, prevent emitting debug information
24857 for incomplete records, emit the information only when the record is
24859 (components_to_record): New parameter defer_debug.
24860 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
24861 (gnat_to_gnu_field_decl): New function.
24862 (substitution_list, annotate_rep): Call it.
24863 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
24864 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
24865 No longer update discriminants to not be a COMPONENT_REF.
24866 (copy_alias_set): Strip padding from input type; also handle
24867 unconstrained arrays properly.
24869 * gigi.h (write_record_type_debug_info): New function.
24870 Convert to use ANSI-style prototypes. Remove unused
24871 declarations for emit_stack_check, elab_all_gnat and
24872 set_second_error_entity.
24873 (gnat_to_gnu_field_decl): New decl.
24875 * utils.c (write_record_type_debug_info): New function.
24876 (finish_record_type): Delegate generation of debug information to
24877 write_record_type_debug_info.
24878 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
24879 (update_pointer_to): Fix pasto.
24880 (convert) <UNION_TYPE>: Accept slight type variations when
24881 converting to an unchecked union type.
24883 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
24884 replace the N_Freeze_Entity with a null statement.
24886 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
24887 within a constrained subcomponent of an enclosing record, place the
24888 freeze nodes in the scope stack entry for the enclosing record.
24889 (Undelay_Type): New Subprogram.
24890 (Set_Small_Size): Pass T, the type to modify; all callers changed.
24891 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
24892 within records; allow them to have freeze nodes if their base types
24895 * exp_util.adb (Remove_Side_Effects): Properly test for
24896 Expansion_Delayed and handle case when it's inside an
24897 N_Qualified_Expression.
24899 * sem_ch3.adb (Derived_Type_Declaration): New predicate
24900 Comes_From_Generic, to recognize accurately that the parent type in a
24901 derived type declaration can be traced back to a formal type, because
24902 it is one or is derived from one, or because its completion is derived
24904 (Constrain_Component_Type): If component comes from source and has no
24905 explicit constraint, no need to constrain in in a subtype of the
24907 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
24908 Minor change to propagate Is_Ada_2005 flag
24910 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
24911 Expansion_Delayed is False.
24912 (assoc_to_constructor): Ignore fields that have a
24913 Corresponding_Discriminant.
24914 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
24915 function returns "by target", dereference the target pointer using the
24916 type of the actual return value.
24917 <all>: Be prepared for a null gnu_result.
24918 (processed_inline_subprograms): Check flag_really_no_inline
24919 instead of flag_no_inline.
24920 (set_second_error_entity): Remove unused function.

24925 2005-03-15 Robert Dewar <dewar@adacore.com>
24926 Ed Schonberg <schonberg@adacore.com>
24927 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24929 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
24930 Must_Be_Byte_Aligned for cases where we do not need to use a
24931 System.Pack_nn unit.
24933 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
24935 Needed now that we do some processing for IN parameters as well. This
24936 may well fix some unrelated errors.
24937 (Expand_Call): Handle case of unaligned objects (in particular those
24938 that come from packed arrays).
24939 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
24940 renamed entity is an inherited operation, re-expand the call using the
24941 original operation, which is the one to call.
24942 Detect attempt to inline parameterless recursive subprogram.
24943 (Represented_As_Scalar): Fix to work properly with private types
24944 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
24945 accurate estimate. Yields True in far fewer cases than before,
24946 improving the quality of code that depends on this test.
24948 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
24949 over both visible and private declarations to remove them from tree,
24950 and mark subprograms declared in package as eliminated, to prevent
24951 spurious use in subsequent compilation of generic units in the context.
24953 * exp_util.ads: Minor cleanup in variable names
24955 * sem_eval.ads, sem_eval.adb: Minor reformatting
24956 (Compile_Time_Known_Bounds): New function
24958 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24960 * exp_ch7.adb (Convert_View): Use base types of underlying types when
24961 determining whether an unchecked conversion is needed for the argument
24962 of an initialization call.
24964 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24966 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
24967 that appears in the instantiation rather than the internal subtype
24968 generated in the wrapper package, to avoid anomalies in gigi when the
24969 target is derived from a private type whose full view is an access type.
24971 2005-03-15 Robert Dewar <dewar@adacore.com>
24973 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
24975 Add documentation to replace the use of this flag
24976 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
24979 2005-03-15 Thomas Quinot <quinot@adacore.com>
24981 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
24982 here from exp_attr so it can be shared between exp_attr and exp_dist.
24983 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
24984 all TSS names, not a subset thereof, and the previous name introduced
24985 an unnecessarily confusion that a distinction might exist between
24986 "OK" TSS names and some "not OK" TSS names.
24988 2005-03-15 Doug Rupp <rupp@adacore.com>
24990 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
24993 2005-03-15 Pascal Obry <obry@adacore.com>
24994 Eric Botcazou <ebotcazou@adacore.com>
24998 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
24999 when IN_RTS. This is to work around a bootstrap path problem.
25001 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
25002 table and pass it to __gnat_install_SEH_handler().
25003 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
25005 * lang.opt: Fix specification of -fRTS=.
25007 2005-03-15 Doug Rupp <rupp@adacore.com>
25008 Bernard Banner <banner@adacore.com>
25009 Vincent Celier <celier@adacore.com>
25010 Arnaud Charlet <charlet@adacore.com>
25013 This change works fine when gnatlib is built from the gcc directory,
25014 but does not work when using the libada Makefile, since GCC_FOR_TARGET
25015 is not passed to ada/Makefile.in, so more work is needed by a
25016 Makefile/configure expert.
25018 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
25019 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
25020 Setup gnatlink switch -M for x86_64 linux, as it is already setup
25022 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
25023 Run ranlib on libgccprefix.a
25024 Define PREFIX_OBJS for Darwin, to build libgccprefix.
25025 (ADA_INCLUDE_SRCS): Split Ada packages.
25027 2005-03-15 Robert Dewar <dewar@adacore.com>
25029 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
25031 * impunit.adb: Add GNAT.UTF_32
25033 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
25035 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
25036 now uses GNAT.UTF_32).
25038 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
25039 capabilities for categorizing characters using Unicode categories
25041 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25043 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
25044 instantiation that has been rewritten as a package body, retrieve spec
25045 to generate proper name for implicit_with_clause.
25046 (Install_Parents): Recognize a parent that is an instantiation but has
25047 been rewritten as a package declaration during analysis.
25049 2005-03-15 Javier Miranda <miranda@adacore.com>
25050 Ed Schonberg <schonberg@adacore.com>
25052 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
25053 parameter reported some error we immediately return. This improves the
25054 behaviour of the frontend in case of errors.
25055 (Install_Parent, Remove_Parent): Introduce new flag
25056 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
25057 ancestor of a generic child unit, when the child is being instantiated.
25058 (Inline_Instance_Body): If we are compiling the private
25059 part or the body of a child unit, restore the proper visibility of the
25060 parents after compiling the instance body.
25062 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25063 Javier Miranda <miranda@adacore.com>
25066 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
25067 of a private type, in which case it is underlying_type that denotes
25068 the proper task. Also modified to use the new entity attribute
25069 that is directly available in the task type and task subtype entities
25070 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
25071 arrays when other dimensions than the first are constrained by
25072 discriminants of an enclosing record.
25073 (Insert_Explicit_Dereference): If the prefix is an indexed component or
25074 a combination of indexed and selected components, find ultimate entity
25075 and generate the appropriate reference for it, to suppress spurious
25077 (Note_Possible_Modification): If an entity name has no entity, return.
25078 (Is_Variable): A function call never denotes a variable.
25079 (Requires_Transient_Scope): For record types, recurse only on
25080 components, not on internal subtypes that may have been generated for
25081 constrained components.
25083 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25085 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
25086 Eliminated as candidates for resolution. Both efficient, and avoids
25087 anomalies with operators declared in deleted code.
25088 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
25089 expansion is disabled (as when compiling a generic) to prevent spurious
25090 warnings on prefixes of selected components.
25092 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25094 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
25095 attached to a list before checking whether it appears in the private
25096 declarations of the current package.
25097 (Make_Inequality_Operator): Insert declaration in proper declarative
25098 list rather than just setting the Parent field, so that
25099 Is_Private_Declaration can handle it properly.
25101 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25103 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
25104 a renaming a body, check that the renamed subprogram in not intrinsic.
25105 (Find_Direct_Name): If several use_visible entities hide
25106 each other, and the context is a predefined file compiled through
25107 rtsfind, keep only the entity that comes from a predefined file.
25109 2005-03-15 Geert Bosch <bosch@adacore.com>
25111 * s-fatgen.adb (Valid): Extend special exceptions to account for long
25112 long float padding to also cover AMD64 and IA64.
25114 2005-03-15 Gary Dismukes <dismukes@adacore.com>
25116 * s-imgwch.adb: Add with and use of Interfaces.
25117 (Img_Wide_Character): Change type of Val to Unsigned_16.
25118 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
25120 2005-03-15 Matthew Gingell <gingell@adacore.com>
25122 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
25124 2005-03-15 Robert Dewar <dewar@adacore.com>
25126 * usage.adb: Add missing lines for -gnat95 and -gnat05 switches
25128 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
25130 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
25132 2005-03-15 Robert Dewar <dewar@adacore.com>
25134 * s-bitops.adb, s-bitops.ads,
25135 s-taprop-os2.adb, s-intman-vms.ads, s-intman-vxworks.ads,

25614 and the result type is set, no further analysis is needed.
25615 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
25616 mark in function specification, in a context where the formals are
25617 visible and hide outer homographs.

25623 procedure", covering the case of a call to a formal abstract procedure
25624 that has statically tagged operands.
25625 (Check_Dispatching_Call): Check for the case of an actual given by
25626 a tag-indeterminate function call whose type is an ancestor of the
25627 containing call's associated tagged type. This situation can occur
25628 for inherited primitives with function defaults. In this case we
25629 use the tagged type's tag directly as the controlling argument for
25631 (Expand_Call): Name change on call to Expand_Dispatch_Call.
25633 * sprint.adb (Sprint_Node_Actual): Split
25634 N_Formal_Subprogram_Declaration into two alternatives for the new
25635 cases N_Formal_Abstract_Subprogram_Declaration and

25656 * sinput.ads, sinput.adb (Skip_Line_Terminators): Extend to deal with
25657 wide character UTF_32 line terminators.
25658 Initialize Main_Source_File to avoid error when no main

25696 GNAT.OS_Lib.Set_Close_On_Exec.
25698 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
25699 the parent side as close-on-exec so that they are not inherited by the
25702 * g-os_lib.ads, g-os_lib.adb (Set_Close_On_Exec): New subprogram to
25703 set or clear the FD_CLOEXEC flag on a file descriptor.
25705 2005-02-09 Eric Botcazou <ebotcazou@adacore.com>
25706 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
25710 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
25711 on the field if Pragma Component_Alignment (Storage_Unit).
25712 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
25713 side-effects as if it were a constant; also make SAVE_EXPR to protect
25715 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
25717 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.

25731 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25733 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
25734 component of an array of arrays in an assignment context, and the
25735 aggregate has component associations that require sliding on
25736 assignment, force reanalysis of the aggregate to generate a temporary
25737 before the assignment.
25738 (Must_Slide): Make global to the package, for use in Gen_Assign.
25740 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25742 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
25743 unchecked union with no inferable discriminants, return a
25744 Raise_Program_Error node, rather than inserting it at the point the
25746 (Expand_Record_Equality, Component_Equality): Handle properly the case
25747 where some subcomponent is an unchecked union whose generated equality
25748 code raises program error.
25750 2005-02-09 Doug Rupp <rupp@adacore.com>
25752 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.

25756 Arnaud Charlet <charlet@adacore.com>
25758 * init.c (__gnat_initialize): Add a new parameter eh which contains the
25759 address of the exception registration. The Win32 version of this
25760 routine calls __gnat_install_SEH_handler() to initialize the SEH
25761 (Structured Exception Handling) handler.
25762 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
25763 SEH (Structured Exception Handling) now.
25764 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
25765 (__gnat_initialize for ppc-vxworks): Adjust comments and the
25766 preprocessor condition protecting the call to the extra eh setup
25767 subprogram, which is only available for the ppc target.
25768 (__gnat_clear_exception_count): replaced reference to
25769 variable taskIdCurrent by call to taskIdSelf(), cleaner.
25771 * seh_init.c: New file.
25773 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
25774 (GNATBIND_OBJS): Idem.
25776 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
25777 routine takes a new parameter (a pointer to the exception registration
25778 for the SEH (Structured Exception Handling) support.
25780 * raise.h: (__gnat_install_SEH_handler): New prototype.
25781 Update copyright notice.
25783 * s-tassta.adb (Task_Wrapper): Declare the exception registration
25784 record and initialize it by calling __gnat_install_SEH_handler.
25786 2005-02-09 Vincent Celier <celier@adacore.com>
25788 * make.adb (Gnatmake): Do not fail when the main project has no object

25809 -shared-libgcc is now used by default on some systems (e.g. linux with
25811 Remove references to Makefile.prolog/generic, no longer used.
25813 2005-02-09 Vincent Celier <celier@adacore.com>
25815 * prj-makr.adb (Process_Directory): Put file name in canonical case
25816 before matching against the patterns.
25817 If gnatname has been invoked as <prefix>-gnatname
25818 then invoke the compiler as <prefix>-gcc, not just "gcc".
25820 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25822 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
25823 with expansion disabled. The actual subtype is needed among other
25824 places when the selected component appears in the context of a loop
25825 bound, and denotes a packed array.
25826 (Operator_Check): Always use the first subtype in the
25827 error message, to avoid the appearance of internal base types.
25828 (Transform_Object_Operation): Copy each actual in full
25829 to the parameter associations of the constructed call, rather than
25830 using the shallow copy mechanism of New_Copy_List. This ensures that
25831 the chaining of named associations is done properly.
25832 (Complete_Object_Operation): Rewrite node, rather than
25833 replacing it, so that we can trace back to the original selected
25836 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
25837 and calls that use object notation, if the called function is not
25838 declared in a withed unit, place the elaboration constraint on the
25839 unit in the context that makes the function accessible.
25840 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
25841 imposes an elaboration constraint between two packages.
25843 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25845 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
25846 views of a private type after handling its private dependents, to
25847 maintain proper stack discipline between entry and exit from the
25850 2005-02-09 Cyrille Comar <comar@adacore.com>

25865 2005-02-09 Robert Dewar <dewar@adacore.com>
25867 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
25868 Slight fix to documentation of -gnaty with no parameters
25870 * xr_tabls.ads: Add ??? comment for missing overall comment
25872 * xsinfo.adb: Make default file name be sinfo.h, since this is what
25873 we now use by default.
25875 * xsnames.adb: Adjust end of file test to look for five space followed
25876 by '#' instead of six spaces. The format of xsnames.adb was modified
25877 in the last update.
25879 * a-numeri.ads: Add reference to AI-388 for greek letter pi
25882 * clean.adb: Minor reformatting.
25884 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
25885 gnatname.adb: Minor reformatting
25886 Add 2005 to copyright output when utility is run
25888 * csets.adb: Eliminate obsolete comment
25890 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
25893 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
25895 2005-02-09 Sergey Rybin <rybin@adacore.com>
25897 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
25898 the difference between compact and incompact layout and add the record
25899 representation clause to the example illustrating different layouts.
25900 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
25901 component clauses").
25903 2005-02-09 Florian Villoing <villoing@adacore.com>
25905 * gnat_ugn.texi: Fix typos.
25906 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
25908 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
25909 in the generated documentation.
25911 2005-02-09 Arnaud Charlet <charlet@adacore.com>
25913 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

25953 * exp_util.ads: Minor correction in comment.
25955 2005-02-09 Arnaud Charlet <charlet@adacore.com>
25957 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
25958 since this procedure is now too complex to be worth inlining.

25962 * utils.c (gnat_define_builtin): Remove.
25963 (gnat_install_builtins): Use build_common_builtin_nodes.

26596 2004-12-07 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26597 Olivier Hainque <hainque@adacore.com>
26598 Eric Botcazou <ebotcazou@adacore.com>
26600 * decl.c (maybe_pad_type): Use TYPE_SIZE_UNIT of the input type for
26601 TYPE_SIZE_UNIT of result type if SIZE is not specified.
26602 (make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation
26603 of a bitfield, which we know is useless and causes trouble because of
26604 alignment implications.
26606 * utils.c (create_var_decl): Set DECL_COMMON again on targets without
26608 (process_attributes): Clear DECL_COMMON again when a section attribute
26610 (finish_record_type): Independently track if RECORD_TYPE has SIZE and/or
26611 SIZE_UNIT already set and use to compute final SIZE and SIZE_UNIT.
26612 (create_field_decl): Special case ADDRESSABLE negative to mean
26613 "no bitfield creation", to be used by make_aligning_type. Don't
26614 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
26615 fields claimed addressable still have to be bitfields. Use
26616 value_factor_p instead of a raw binop construction to check for the
26617 position's alignment.
26619 2004-12-07 Geert Bosch <bosch@adacore.com>
26621 * eval_fat.adb: Revert previous change.
26623 2004-12-07 Thomas Quinot <quinot@adacore.com>
26624 Ed Schonberg <schonberg@adacore.com>
26626 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
26627 with an implicit dereference as its prefix, use
26628 Insert_Explicit_Dereference instead of merely rewriting the prefix into
26629 an explicit dereference. This ensures that a reference to the original
26630 prefix is generated, if appropriate.
26632 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
26633 dereference is rewritten to an explicit one, generate a reference to
26634 the entity denoted by its prefix using the original prefix node, so
26635 the dereference can be properly recorded as a read of the denoted
26636 access value, if appropriate.
26638 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
26639 emitting 'assigned but never read' warning on a variable on the basis
26640 that it has an access type.
26641 (Check_References): Emit unreferenced warning when the scope is a
26644 2004-12-07 Robert Dewar <dewar@adacore.com>
26645 Ed Schonberg <schonberg@adacore.com>
26647 * exp_ch6.adb (Expand_Call): Add comment on handling of back end
26650 * exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
26651 leaving call unchanged.
26652 This deals with the case where the pragma Import specified
26653 an external name, to be handled by the back end.
26655 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
26656 subprogram which is Imported with convention Intrinsic if an
26657 External_Name argument is specified.
26658 (Process_Import_Or_Interface): Properly diagnose link name argument.
26659 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
26660 with Sem_Ch6.Cannot_Inline.
26661 (Process_Inline): Provide separate warning for inapplicable inline
26663 (Cannot_Inline): Reject subprograms that have an at_end handler, so that
26664 treatment is uniform on different targets.
26666 2004-12-07 Ed Schonberg <schonberg@adacore.com>
26668 * exp_ch7.adb (Expand_Cleanup_Actions): If statement sequence of
26669 construct is rewritten, preserve end label to permit source navigation.
26671 2004-12-07 Thomas Quinot <quinot@adacore.com>
26673 * exp_dist.adb (Specific_Build_General_Calling_Stubs,
26674 Specific_Build_Stub_Target): New subprograms.
26675 (Build_Subprogram_Calling_Stubs): Make this procedure independent from
26676 the PCS implementation used, using the above PCS-customized subprograms.
26677 Minor reformatting.
26678 (PolyORB_Support.Helpers): New subunit containing supporting subprograms
26679 for generation of DSA code targeted to the PolyORB PCS.
26680 (Add_Stub_Type): Rewrite to isolate the parts that are specific to one
26681 implementation of the partition communication subsystem in ancillary
26683 (Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,
26684 PolyORB_Support.Build_Stub_Type): New subrograms containing the
26685 PCS-specific part of Add_Stub_Type.
26686 (Insert_Partition_Check): Use runtime library function to perform
26689 * rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref
26690 (RE_Same_Partition): New entity, from s-parint.
26692 * s-parint.ads, s-parint.adb (Same_Partition): New subprogram.

26702 * g-os_lib.adb (Spawn): Explicitly initialize Saved_Error to avoid a
26703 compile-time warning.
26705 2004-12-07 Robert Dewar <dewar@adacore.com>
26707 * g-regpat.adb: (Match): Change a misuse of or to or else
26709 2004-12-07 Ed Schonberg <schonberg@adacore.com>
26712 (Generate_Reference): Handle properly a reference to an entry formal,
26713 when an accept statement has a pragma Unreferenced for it.
26715 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
26716 and the Has_Pragma_Unreferenced flag for each formal before analyzing
26717 the body, to ensure that warnings are properly emitted for each accept
26718 statement of a given task entry.
26720 2004-12-07 Vasiliy Fofanov <fofanov@adacore.com>
26722 * Makefile.in: Add support for foreign threads on VMS.
26724 2004-12-07 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26726 * misc.c (gnat_types_compatible_p, LANG_HOOKS_TYPES_COMPATIBLE_P):

26738 * nlists.adb (Prepend_Debug): Remove parameters and nest within
26740 (Remove_Next_Debug): Same fix
26742 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
26743 maintain back pointers now, though we did not used to, and comments
26745 (Prepend): Remove pragma Inline.
26746 (Remove_Next): Same cleanup
26748 2004-12-07 Thomas Quinot <quinot@adacore.com>
26750 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
26751 used to record an implicit dereference as a read operation on its
26752 prefix when operating under -gnatc. Necessary to avoid spurious
26753 'variable assigned but never read' warnings in that mode.
26754 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
26755 is a non-overloaded implicit dereference, call the above subprogram to
26756 ensure proper recording of references.
26758 2004-12-07 Gary Dismukes <dismukes@adacore.com>
26760 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
26761 to be resolved later as part of Analyze_Iteration_Scheme's call to
26764 2004-12-07 Ed Schonberg <schonberg@adacore.com>
26766 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

26777 documentation of the behaviour of these functions when passed an IP
26778 address that has no record in the system hosts database and no reverse

26791 Add some ??? comments asking for more comments
26793 * s-poosiz.adb: Minor reformatting
26794 Add comments on alignment requirement
26796 * sinfo.ads: Remove obsolete comment and fix typo.
26798 2004-12-07 Vincent Celier <celier@adacore.com>
26799 Sergey Rybin <rybin@adacore.com>
26801 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
26802 Files" with the new tool and package names.
26803 Reformatting to suppress most of the warnings for line too long
26804 Document the new section "Project Search Path:" in the output of
26806 Add gnatmetric section
26808 2004-12-07 Vincent Celier <celier@adacore.com>
26810 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
26811 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
26812 and -eit to -ept. Added qualifier
26813 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
26815 2004-11-27 Andreas Schwab <schwab@suse.de>
26817 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
26819 2004-11-25 Arnaud Charlet <charlet@adacore.com>
26821 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
26822 internal implementation unit GNAT.Sockets.Thin,
26823 as their usage for sockets is non-portable (using the read and write
26824 functions from the system runtime library is fine on UNIX but won't
26825 work under Windows).
26827 * mingw32.h: Update copyright notice.
26829 2004-11-25 Arnaud Charlet <charlet@adacore.com>
26831 * ada-tree.h: Minor reformatting of previous change to avoid lines
26832 longer than 79 characters.

26865 (__gnat_dup2): New function.
26866 (__gnat_is_symbolic_link): Enable the effective body of this
26867 function when __APPLE__ is defined.
26869 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
26872 2004-11-18 Olivier Hainque <hainque@adacore.com>
26874 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
26875 address of which may be used to represent "others" and "all others"
26876 choices in exception tables, instead of the current harcoded
26877 (void *)0 and (void *)1.
26878 (Setup_Exception): Do nothing in the GNAT SJLJ case.
26880 * gigi.h (others_decl, all_others_decl): New decls representing the
26881 new Others_Value and All_Others_Value objects.
26882 (struct attrib): Rename "arg" component as "args", since GCC expects a
26883 list of arguments in there.
26885 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
26886 corresponding objects exported by a-exexpr, instead of hardcoded dummy
26889 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
26890 others_decl and all_others_decl instead of hardcoded dummy addresses
26891 to represent "others" and "all others" choices, which is cleaner and
26892 more flexible with respect to the possible eh pointer encoding policies.
26894 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
26895 (process_attributes): Account for the naming change of the "args"
26896 attribute list entry component.
26898 * decl.c (build_attr_list): Rename into prepend_attributes to allow
26899 cumulating attributes for different entities into a single list.
26900 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
26901 attributes for the current entity and propagate first subtype
26902 attributes to other subtypes.
26903 <E_Procedure>: Attribute arguments are attr->args and not
26904 attr->arg any more.
26905 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
26906 argument provided, as this is what GCC expects. Use NULL_TREE instead
26909 2004-11-18 Robert Dewar <dewar@adacore.com>
26911 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
26912 Minor reformatting througout (including new function specs)
26913 Add ??? comments asking for clarification.
26915 2004-11-18 Thomas Quinot <quinot@adacore.com>
26917 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
26918 incomplete duplicate implementation of this subprogram from butil.
26920 2004-11-18 Thomas Quinot <quinot@adacore.com>
26922 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
26923 procedures factors the common processing for building an RPC receiver
26924 for an RCI package or an RACW type.
26925 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
26926 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
26927 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
26929 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
26931 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
26933 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
26934 distribution subprogram identifiers that are either subprogram numbers

26937 string distribution identifiers assigned to a given subprogram.
26938 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
26939 (Add_RAS_Dereference_TSS): Add comments.
26940 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
26941 is not referenced yet because it will be used by the PolyORB DSA
26943 (Insert_Partition_Check): Remove fossile code.
26944 (First_RCI_Subprogram_Id): Document this constant.
26945 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
26947 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
26948 replaced with calls to Get_Library_Unit_Name_String. Previously there
26949 were several instances of the same code in different locations in the
26950 compiler; this checkin completes the replacement of all of these
26951 instances with calls to a common subprogram.
26952 Minor reformatting.
26954 * sem_dist.adb: Remove comment noting that RPC receiver generation
26955 should be disabled for RACWs that implement RASs.
26956 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.

26961 (Note_Possible_Modification): Generate a reference only
26962 if the context comes from source.
26964 * snames.ads (PCS_Names): New subtype corresponding to names of
26965 supported implementations of the Partition Communication Subsystem
26966 (PCS) (i.e. the runtime library support modules for the distributed

26980 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
26981 (Expand_Pragma_Psect_Object): New procedure
26982 These procedures contain the revised and cleaned up processing for
26983 these two pragmas. This processing was formerly in Sem_Prag, but
26984 is more appropriately moved here. The cleanup involves making sure
26985 that the pragmas are properly attached to the tree, and that no
26986 nodes are improperly shared.
26988 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
26989 pragmas to Exp_Prag, which is more appropriate.
26990 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
26991 check for duplicates Remove use of Is_Psected flag, no longer needed.
26992 Use new Make_String_Literal function with string.
26994 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
26995 that are functions return universal values, that have to be converted
26996 to the context type.
26997 Use new Make_String_Literal function with string.
26998 (Get_Stream_Convert_Pragma): New function, replaces the use of
26999 Get_Rep_Pragma, which had to be kludged to work in this case.
27001 * freeze.adb: Use new Has_Rep_Pragma function
27003 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
27004 function with string.
27005 Use new Has_Rep_Pragma function.
27007 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
27010 2004-11-18 Robert Dewar <dewar@adacore.com>
27012 * errout.ads, errout.adb: (First_Sloc): New function
27014 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
27015 check (-gnatyx) instead of being included as a redundant construct
27018 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
27019 Style_Check_Order_Subprograms.
27021 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
27022 stylesw.adb: Add Style_Check_Xtra_Parens
27024 * usage.adb: Add line for -gnatyx (check extra parens)

27029 Robert Dewar <dewar@adacore.com>
27031 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
27032 discriminant of a constrained subtype, analyze the copy of the
27033 corresponding constraint, because in some cases it may be only
27034 partially analyzed.
27035 Removes long-lived ??? comments.
27037 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
27038 handled controlled or secondary-stack expressions within the
27039 iteration_scheme of a loop.
27041 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
27042 bounds that may contain functions calls, to prevent memory leaks when
27043 the bound contains a call to a function that uses the secondary stack.
27044 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
27045 generate temporaries for loop bounds that might contain function calls
27046 that require secondary stack and/or finalization actions.
27048 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
27049 selected component and the selector is overloadable (not just a
27050 function) treat as function call, Analyze_Call will disambiguate if
27052 (Analyze_Selected_Component): Do not generate an actual subtype for the
27053 selected component if expansion is disabled. The actual subtype is only
27054 needed for constraint checks.
27055 (Analyze_Allocator): If restriction No_Streams is set, then do
27056 not permit objects to be declared of a stream type, or of a
27057 composite type containing a stream.
27059 * restrict.ads: Remove the a-stream entry from Unit_Array, since
27060 No_Streams no longer prohibits with'ing this package.
27062 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
27063 discriminants, but the parent base has unknown discriminants, there is
27064 no discriminant constraint to inherit. Such a discrepancy can arise
27065 when the actual for a formal type with unknown discriminants is a
27066 similar private type whose full view has discriminants.
27067 (Analyze_Object_Declaration): If restriction No_Streams is set, then
27068 do not permit objects to be declared of a stream type, or of a
27069 composite type containing a stream.
27071 2004-11-18 Ed Schonberg <schonberg@adacore.com>
27073 * exp_dbug.ads: Update documentation to reflect simpler encoding for
27074 protected operations.
27076 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
27077 generated name, it complicates decoding in gdb and hinders debugging
27078 of protected operations.
27079 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
27080 flag for the protected entry barrier function.
27081 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
27082 flag for the protected entry function.

27088 * Makefile.in: Inform the value of the variable GMEM_LIB in the
27089 Darwin-specific section.
27091 * lang-specs.h: Change the placement of the %1 marker.
27092 Works around the fact that gcc adds -fPIC by default under Darwin.
27094 2004-11-18 Ed Schonberg <schonberg@adacore.com>
27096 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
27097 type of the object with the packed array type, set the Analyzed flag
27098 on the object if it is an entity or simple indexed component, to avoid
27099 spurious type errors.

27103 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
27104 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
27105 separate line from the version message.
27107 2004-11-18 Ed Falis <falis@adacore.com>
27109 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
27111 (init_float): Eliminate initialization of floating point status for
27112 AE653. The instructions have no effect for vThreads.
27114 2004-11-18 Vincent Celier <celier@adacore.com>
27116 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
27117 gnatbind is invoked with -shared.
27119 2004-11-18 Jose Ruiz <ruiz@adacore.com>
27121 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
27122 for Detect_Blocking which is redundant with the check done within the
27123 procedure Protected_Single_Entry_Call.
27124 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
27125 Detect_Blocking which is redundant with the check done within the
27126 procedure Protected_Single_Entry_Call.
27128 2004-11-18 Vincent Celier <celier@adacore.com>
27130 * makegpr.adb (Compile): Put the compiling switches (in package
27131 Compiler and on the command line) immediately after "-c", instead of
27132 at the end of the command line invocation of the compiler, when
27133 compiling a non-Ada file.
27134 (Build_Global_Archive): When there is no need to rebuild the archive,
27135 set Global_Archive_Exists, so that the archive is passed to the linker
27138 2004-11-18 Robert Dewar <dewar@adacore.com>
27139 Sergey Rybin <rybin@adacore.com>
27142 Remove extra paren check from list of checks for redundant constructs
27143 Add documentation of new -gnatyx style check (check extra parens)
27144 Remove paragraph about gnatelim debug options.
27146 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
27147 objects rather than forbidding dependencies on the package Ada.Streams.
27149 * sinfo.ads: Add ??? note that we should document pragmas passed to
27152 * g-expect.ads: Fix a few typos in the comments.
27154 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
27156 * misc.c (gnat_handle_option): Use %< and %> for quoting in
27159 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
27161 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
27163 2004-11-07 Andreas Schwab <schwab@suse.de>
27165 * Makefile.in (install-gnatlib): Remove spurious hyphen.
27167 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
27170 * Makefile.in (darwin): Set soext to .dylib.
27172 2004-10-26 Vincent Celier <celier@gnat.com>
27173 Thomas Quinot <quinot@act-europe.fr>
27175 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
27176 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
27177 there is no use of GNAT.Sockets.Constants.
27178 Remove remaining pragma Import for C_Write
27179 Remove C_Read and C_Write from internal implementation unit
27180 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
27181 the read and write functions from the system runtime library is fine
27182 on UNIX but won't work under Windows).
27184 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
27185 (Check_Selector): Use C_Recv instead of C_Read.
27186 Selectors are the GNAT.Sockets abstraction to perform a select()
27187 call on a set of descriptors. To allow abortion of an ongoing
27188 select operation, some data is written to a dedicated socket that
27189 is always monitored.
27190 Under Windows, the write and read library functions cannot operate
27191 on sockets, so we need to use send and recv instead, which is portable
27192 across all supported platforms.
27194 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
27195 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
27196 (using the read and write functions from the system runtime library is
27197 fine on UNIX but won't work under Windows).
27199 2004-10-26 Nicolas Setton <setton@act-europe.fr>
27201 * mlib-tgt-darwin.adb: New file.
27203 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
27204 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
27205 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
27206 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
27209 * Makefile.in: Add support for building shared libraries under Darwin.
27210 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
27211 the low level EH init subprogram to be called from __gnat_initialize.
27213 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
27214 indicates which options to pass to the archive indexer.
27216 * mlib-utl.adb: Add support for calling ranlib with additional
27217 options. This is needed for instance under Mac OS X.
27218 (Ranlib_Options): New global variable, used to store the potential
27219 options to pass to ranlib.
27220 (Ar): Use Ranlib_Options when spawning ranlib.
27221 (Initialize): Set the value of ranlib option.
27223 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
27225 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
27226 instead of 8K, to reflect the real potential needs for stack-checking
27229 2004-10-26 Pascal Obry <obry@gnat.com>
27231 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
27233 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
27234 Windows only the initial thread stack size can be set so it is good to
27235 start we a low stack size.
27236 The OS will adjust the size as needed.
27238 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
27239 Nicolas Setton <setton@act-europe.fr>
27241 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
27242 "__unix__" instead of "unix".
27243 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
27244 sections were just mistakenly ignored. The former is
27245 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
27246 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
27247 of hpux. This prevents an unwanted definition of the symbol
27248 convert_addresses in adaint.o.
27250 2004-10-26 Gary Dismukes <dismukes@gnat.com>
27252 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
27253 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
27255 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27257 * a-filico.ads, a-filico.adb: fix incorrect header.
27259 2004-10-26 Javier Miranda <miranda@gnat.com>
27261 * a-ststio.ads: Fix typo in identifier
27263 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27265 * sem_ch4.adb: Minor reformatting.
27267 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27269 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
27270 enabled, check the result of unary and binary operations when the
27271 expression is the right-hand side of an assignment.
27273 2004-10-26 Vincent Celier <celier@gnat.com>
27275 * clean.adb (Delete): Do not output warnings when in quiet output and
27276 not in verbose mode.
27277 (Force_Deletions): New Boolean flag, defaulted to False
27278 (Delete): Only delete a file if it is writable, and when
27279 Force_Deletions is True.
27280 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
27281 (Usage): Line for new switch -f
27282 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
27285 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
27287 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
27288 JM type only if its size matches that of the wrapper. When a size is
27289 prescribed and the field is not aliased, remove the wrapper of a JM
27290 type only if the size is not greater than that of the packed array.
27291 (gnat_to_gnu_entity): Change the extension of packed array wrappers
27294 2004-10-26 Geert Bosch <bosch@gnat.com>
27296 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
27297 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
27298 (Pred): Implement in terms of Succ.
27300 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27302 * exp_aggr.adb (Safe_Component): An aggregate component that is an
27303 unchecked conversion is safe for in-place use if the expression of the
27304 conversion is safe.
27305 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
27306 be expandable in place even if the aggregate does not come from source.
27307 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
27308 designated object of an allocator in place, rather than building it
27309 first on the stack. The previous scheme forces a full copy of the array,
27310 and may be altogether unsusable if the size of the array is too large
27311 for stack allocation.
27313 2004-10-26 Robert Dewar <dewar@gnat.com>
27315 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
27316 compares if the component is atomic.
27318 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
27319 array assignment if the component type is atomic.
27321 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27322 Eric Botcazou <ebotcazou@act-europe.fr>
27324 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
27325 is aliased and is a by_reference type, do not pass by copy.
27326 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
27327 detect whether the call is in the right side of an assignment or
27328 the expression of an object declaration. Recurse on component
27329 association within aggregates.
27330 Call it in the condition that determines whether the temporary is
27331 necessary for correct stack-checking.
27333 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27335 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
27336 RACW_Type, used in the PolyORB version.
27337 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
27338 version and the GARLIC version.
27340 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
27341 Rename RCI_Info to RCI_Locator for better consistency between the
27342 GARLIC and PolyORB versions of the distributed systems annex.
27343 (DSA_Implementation_Name): This enumeration lists the possible
27344 implementations of the Partition Communication Subsystem for the
27345 Distributed Systems Annex (DSA). The three available implementations
27346 are the dummy stub implementation (No_DSA), and two versions based on
27347 two different distribution runtime libraries: GARLIC and PolyORB. Both
27348 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
27350 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
27353 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
27354 between the GARLIC and PolyORB versions of the distributed systems
27356 Remove RE_Unbounded_Reclaim_Pool since it is unused.
27358 2004-10-26 Gary Dismukes <dismukes@gnat.com>
27360 * gnat1drv.adb: Suppress calling the back end when
27361 Frontend_Layout_On_Target is true.
27363 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27365 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
27366 Set_Read_Only): New subprograms.
27367 These new routines allow the user to set or unset the Owner execute
27368 and Owner write permission flags on a file.
27370 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
27371 GNAT.OS_Lib.Set_Executable instead of rolling our own.
27373 2004-10-26 Matthew Gingell <gingell@gnat.com>
27375 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
27377 2004-10-26 Pascal Obry <obry@gnat.com>
27379 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
27380 memory before the faulting page we properly test the process read
27381 access for this address using appropriate Win32 routine.
27382 (HPUX sections): guard with "__hpux__" instead of "hpux".
27384 2004-10-26 Robert Dewar <dewar@gnat.com>
27386 * lib-xref.adb (Generate_Reference): Don't complain about reference to
27387 entry parameter if pragma Unreferenced set, since we do not properly
27388 handle the case of multiple parameters.
27390 2004-10-26 Vincent Celier <celier@gnat.com>
27392 * prj-env.adb: (Contains_ALI_Files): New Boolean function
27393 (Ada_Objects_Path.Add): For a library project, add to the object path
27394 the library directory only if there is no object directory or if the
27395 library directory contains ALI files.
27396 (Set_Ada_Paths.Add.Recursive_Add): Ditto
27398 2004-10-26 Vincent Celier <celier@gnat.com>
27400 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
27401 extension of library projects.
27403 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
27404 path defaults to ".:<prefix>/lib/gnat".
27405 (Parse): For an extending all project, allow direct import of a project
27406 that is virtually extended.
27408 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
27409 the specified name is directly imported, return its ID. Otherwise, if
27410 an extension of this project is imported, return the ID of the
27413 2004-10-26 Robert Dewar <dewar@gnat.com>
27415 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
27416 (Sub3): New procedure, used by Scaled_Divide
27417 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
27418 correct more than one instance of failure to propagate carries
27420 (Double_Divide): Handle overflow case of largest negative number
27421 divided by minus one.
27423 * s-arit64.ads (Double_Divide): Document that overflow can occur in
27424 the case of a quotient value out of range.
27427 2004-10-26 Robert Dewar <dewar@gnat.com>
27429 * s-bitops.adb (Bit_Eq): Remove redundant check.
27431 * s-bitops.ads: Minor comment updates
27432 Change some occurrences of Address to System.Address
27434 * s-carsi8.ads: Fix minor cut-and-paste error in comments
27436 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27438 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
27439 accessibility check to prefix that is a protected operation.
27441 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27443 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
27444 empty, post message on stub.
27446 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27447 Javier Miranda <miranda@gnat.com>
27449 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
27450 current instance appears within a unit that is directly in the context
27452 Used to determine whether the body of the instance should be analyzed
27453 immediately after its spec, to make its subprogram bodies available
27454 for front-end inlining.
27455 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
27456 constraint is not allowed on the component type (AARM 12.5.3(3))
27458 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27460 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
27461 'Storage_Pool): enhance, document & limit detection of non-sharable
27464 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
27466 * s-pooglo.ads: Add more documentation now that this pool is properly
27469 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27471 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
27472 or protected type with discriminants, do not constrain the
27473 corresponding record type if the subtype declaration has no
27474 discriminant constraints. This can be the case in source code, or in
27475 the subtype declaration created to rename an actual type within an
27478 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27480 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
27481 different kind of stub (possibly wrong name for file), do not check
27483 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
27484 includes call to some function that returns an unconstrained type, do
27487 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27489 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
27490 appear in the code for the main unit. Dependencies among units in the
27491 context of the main unit are established when those other units are
27492 compiled. Otherwise spurious elaboration constraints can generate
27493 incorrect elaboration circularities.
27495 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27496 Ed Schonberg <schonberg@gnat.com>
27498 * sem_util.adb (Is_Aliased_View): Defend against the case where this
27499 subprogram is called with a parameter that is not an object name. This
27500 situation arises for some cases of illegal code, which is diagnosed
27501 later, and in this case it is wrong to call Is_Aliased, as that might
27502 cause a compiler crash.
27503 (Explain_Limited_Type): Refine previous fix to include
27504 inherited components of derived types, to provide complete information.
27506 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
27507 is the prival for a protected object.
27508 It is necessary to mark this entity as a variable, in addition to
27509 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
27510 modified to avoid checking the Aliased flag on entities that are not
27511 objects. (Checking that flag for non-objects is erroneous and could
27512 lead to a compiler crash).
27514 2004-10-26 Robert Dewar <dewar@gnat.com>
27516 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
27517 X_Frac = 0.5, then we know that the number X must be positive.
27518 (Succ): Remove the same redundant test, and also fix the primary test
27519 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
27521 (Decompose): Add fuller comments to spec
27523 2004-10-26 Pascal Obry <obry@gnat.com>
27525 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
27526 validity (process must have read access). Set to 0 in all other cases.
27527 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
27528 violation on Win32.
27529 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
27530 segmentation violation.
27532 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
27534 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
27535 whose type is a constructed subtype of an aliased object with an
27536 unconstrained nominal subtype, convert the actual to the constructed
27537 subtype before taking its address.
27539 2004-10-26 Vincent Celier <celier@gnat.com>
27541 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
27542 (Is_Path_Name_Case_Sensitive): New function
27544 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
27545 (Base_Name, Simple_Name, Current_Directory, Compose,
27546 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
27549 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27550 Vasiliy Fofanov <fofanov@act-europe.fr>
27551 Vincent Celier <celier@gnat.com>
27553 * gnat_ugn.texi: Generalize "finding memory problems" section into a
27554 "memory management issues" section and document some of the useful
27555 memory pools provided as part of the GNAT library.
27556 Remove "virtual" from declaration of A::method2 in
27557 the simple example of Ada/C++ mixed system.
27558 Library Projects may be virtually extended: their virtual extensions
27559 are not Library Projects.
27560 Added section on extending project hierarchies.
27562 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
27564 * adaint.c (__gnat_get_libraries_from_registry): Cast value
27566 (__gnat_portable_spawn): Remove const.
27568 * mingw32.h (MAXPATHLEN): Check for previous definition.
27570 2004-10-17 Matthias Klose <doko@debian.org>
27572 * gnatvsn.ads: Set gnat library version to 4.0.
27574 2004-10-05 Vincent Celier <celier@gnat.com>
27576 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
27578 2004-10-04 Laurent Guerby <laurent@guerby.net>
27581 * Makefile.in: Define and use RANLIB_FLAGS.
27583 2004-10-04 Pascal Obry <obry@gnat.com>
27585 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
27586 other x86 platforms).
27588 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
27590 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
27591 in general and triggers stack alignment adjustment for thread entry
27592 points on targets where this is necessary.
27594 2004-10-04 Bernard Banner <banner@gnat.com>
27597 * Makefile.in: Add section for powerpc linux
27598 Add variant i-vxwork-x86.ads
27600 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
27602 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
27604 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
27605 table registration calls when need be. Ensures no reference to the crt
27606 ctors symbol are issued in the SJLJ case, which avoids possible
27607 undefined symbol errors in the case of modules to be statically linked
27610 2004-10-04 Javier Miranda <miranda@gnat.com>
27612 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
27613 in-line the code corresponding to subprogram Analyze_Actuals. In
27614 addition, analyze the actuals only in case of subprogram call.
27616 2004-10-04 Ed Falis <falis@gnat.com>
27618 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size

27629 (Analyze_Block_Statement): Add circuitry to detect following dead code
27630 (Check_Unreachable_Code): Handle case of block exit
27632 2004-10-04 Robert Dewar <dewar@gnat.com>
27634 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
27635 (XMatchD): Avoid warning for Logic_Error call
27637 2004-10-04 Robert Dewar <dewar@gnat.com>
27639 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
27640 consider expressions buried within a procedure actual to be an actual.
27641 This caused some blowups with uses of packed slices within a procedure
27644 2004-10-04 Robert Dewar <dewar@gnat.com>
27646 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
27647 longer need to be initialized to zero.
27648 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
27649 initialized to zero.
27651 * checks.adb (Expr_Known_Valid): Packed arrays are now always
27652 considered valid, even if the representation is modular. That's correct
27653 now that we no longer initialize packed modular arrays to zero.
27655 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
27656 suffixes. These are now documented as the only cases in which the
27657 debugger ignores outer records.
27658 Previously, the spec allowed arbitrary suffixes for this purpose.
27659 Change name of LJM to JM for packed array pad records
27660 Create separate section on packed array handling, and add a whole new
27661 set of comments to this section describing the situation with packed
27662 modular types and justification requirements depending on endianness.
27664 2004-10-04 Robert Dewar <dewar@gnat.com>
27666 * a-except.adb: Add a comment for last change
27668 * einfo.ads: Minor spelling correction in comment
27670 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
27672 * sem_ch11.adb: Fix a case of using | instead of \ for continuation

27679 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
27680 Inline_Always when in Configurable_Run_Time mode.
27682 * sem_prag.adb (Process_Convention): If entity is an inherited
27683 subprogram, apply convention to parent subprogram if in same scope.
27684 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
27685 when in Configurable_Run_Time mode.
27687 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27689 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
27690 class_wide type after component list has been inherited.

27694 * sem_ch12.adb (Check_Generic_Actuals): New predicate
27695 Denotes_Previous_Actual, to handle properly the case of a private
27696 actual that is also the component type of a subsequent array actual.
27697 The visibility status of the first actual is not affected when the
27698 second is installed.
27699 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
27700 make fully recursive the treatment of formals of packages declared
27702 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
27703 the above on exit from an instantiation.
27704 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
27705 current instantiation which is now complete.
27706 (Analyze_Package_Instantiation): No instantiated body is needed if the
27707 main unit is generic. Efficient, and avoid anomalies when a instance
27708 appears in a package accessed through rtsfind.
27710 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27712 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
27713 do not generate a declaration for a temporary if the call is part of a
27714 library-level instantiation.
27716 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27718 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
27719 searching for a limited component to flag.
27721 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
27722 expansion of Input, to account for the fact that the implicit call
27723 generated by the attribute reference must freeze the user-defined
27724 stream subprogram. This is only relevant to 'Input, because it can
27725 appear in an object declaration, prior to the body of the subprogram.
27727 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
27728 expansion can proceed and further errors uncovered.
27729 (Minor clean up): Fix cases of using | instead of \ for continuation
27732 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27734 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
27736 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
27737 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
27738 Use gcc_assert and gcc_unreachable.
27740 * decl.c (gnat_to_gnu_entity, case object): Check and process a
27741 specified alignment before validating size.
27742 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
27743 stripped-down declaration for the type of the inner field when making
27746 * utils.c (finish_record_type): Do not compute the size in units
27747 incrementally. Instead compute it once for the rep clause case.
27748 Use gcc_assert and gcc_unreachable.
27750 2004-10-04 Vincent Celier <celier@gnat.com>
27752 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
27754 (Is_Valid_Path_Name): Take '/' as a directory separator.
27756 2004-10-04 Vincent Celier <celier@gnat.com>
27758 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
27759 (Extended_Project) only if Extended_Project is defined, to avoid
27761 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
27763 (Parse_Single_Project): Ditto.
27765 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
27766 Add_To_Project_Path for virtual projects.
27768 2004-10-04 Vincent Celier <celier@gnat.com>
27770 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

27774 parameter Options_2.
27776 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
27777 Build_Dynamic_Library with an empty Options_2.
27779 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
27782 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
27783 directory separator, if any.
27784 (Gprmake): Do not allow mains on the command line for library projects.
27785 Do not attempt to link when the project is a library project.
27786 (Library_Opts): New table to store Library_Options.
27787 (Build_Library): If Library_Options is specified, pass these options
27788 when building a shared library.
27790 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
27792 * s-tposen.adb (Service_Entry): The object must be always unlocked at

27809 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
27810 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
27811 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
27812 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
27813 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
27814 used to signal whether the compiler creates the required stacks and
27815 descriptors for the different tasks (when True) or it is done by the
27816 underlying operating system at run time (when False).
27817 It is initially set to False in all targets.
27819 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
27820 if it is supported by the target.
27821 (Make_Task_Create_Call): Pass the stack address if it has been
27822 previously created. Otherwise pass a Null_Address.
27824 * snames.adb: Add _stack.
27826 * snames.ads: Add Name_uStack. Required to allow the expander to
27827 statically allocated task stacks.
27829 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
27830 Stack_Address argument.
27831 Check that its value is equal to Null_Address because this target does
27832 not support the static stack allocation.
27834 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
27836 * usage.adb: Change "pragma inline" to "pragma Inline" in information

27841 * exp_dist.adb: Split declaration of asynchronous flag out of
27842 Add_RACW_Read_Attribute.
27843 Minor reformatting for better alignment with PolyORB version.
27844 Store the entity for the asynchronous flag of an RACW, rather than the
27845 expression, in the asynchronous flags table. This will allow this flag
27846 to be used in other subprograms beside Add_RACW_Read_Attribute.
27848 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
27850 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
27851 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,

27853 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
27854 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
27855 sockets constant MSG_NOSIGNAL (Linux-specific).
27856 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
27857 all Send operations.
27858 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
27859 from trigerring SIGPIPE.
27860 Rename components to avoid clash with Ada 2005 possible reserved
27862 (Check_Selector): When the select system call returns with an error
27863 condition, propagate Socket_Error to the caller.
27865 2004-10-01 Jan Hubicka <jh@suse.cz>
27867 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
27869 2004-09-23 Robert Dewar <dewar@gnat.com>

27873 instead do this at freeze time (we won't do it if there is an address
27875 Change "pragma inline" to "pragma Inline" in information and error
27877 Minor reformatting.
27879 * freeze.adb (Check_Address_Clause): Remove previous change, not the
27880 right way of doing things after all.
27881 (Freeze_Entity): For object, set Is_Public for imported entities
27882 unless there is an address clause present.
27884 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
27886 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
27887 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
27888 ensures proper handling of types with rep clauses, which might have
27889 their TYPE_SIZE set already.
27891 2004-09-21 Robert Dewar <dewar@gnat.com>
27893 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
27894 packed array types in both little- and big-endian cases. This change
27895 ensures that we no longer count on the unused bits being initialized
27896 for such types (and in particular ensures that equality testing will
27897 only read the relevant bits).
27898 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
27899 These changes mean that we no longer need to initialize small packed
27901 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
27902 optimization to an LJM field as to its parent field.
27904 * ada-tree.h, trans.c, utils.c, utils2.c:
27905 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
27907 2004-09-20 Jan Hubicka <jh@suse.cz>
27909 * utils.c (gnat_finalize): Remove.
27910 (end_subprog_body): Directly call cgraph_finalize_function;
27911 do not lower the nested functions.
27913 2004-09-20 Robert Dewar <dewar@gnat.com>
27916 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
27917 if an address clause is present, since that means that the Import
27920 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
27922 * 5tsystem.ads: Removed, no longer used.
27924 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
27925 Zack Weinberg <zack@codesourcery.com>
27927 * ada-tree.def: Use tree_code_class enumeration constants
27928 instead of code letters.
27929 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
27930 Update for new tree-class enumeration constants.

27946 an existing directory.
27947 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
27948 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
27949 Convert the result to File_Size.
27951 * prj.ads: (Project_Error): New exception
27953 * prj-attr.adb: Except in procedure Initialize, Fail comes from
27954 Prj.Com, not from Osint.
27955 (Attrs, Package_Attributes): Tables moved to private part of spec
27956 (Add_Attribute, Add_Unknown_Package): Moved to new child package
27958 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
27959 Prj.Project_Error after call to Fail.
27960 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
27961 Fail. Check that package name is not already in use.
27963 * prj-attr.ads: Comment updates to indicate that all subprograms may be
27964 used by tools, not only by the project manager, and to indicate that
27965 exception Prj.Prj_Error may be raised in case of problem.
27966 (Add_Unknown_Package, Add_Attribute): Moved to new child package
27968 (Attrs, Package_Attributes): Table instantiations moved from the body to
27969 the private part to be accessible from Prj.Attr.PM body.

27972 from new package Prj.Attr.PM.
27973 (Parse_Attribute_Declaration): Call Add_Attribute from new package
27976 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
27978 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
27979 instead of Elaboration_Checks).
27981 * a-calend.adb: Minor reformatting
27983 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

28041 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
28042 Common_ATCB record. It contains the dynamic level of protected action
28043 nesting for each task. It is needed for checking whether potentially
28044 blocking operations are called from protected operations.

28082 contains the required machinery for handling that.
28084 * sem_util.ads: Change comment associated to procedure
28085 Check_Potentially_Blocking_Operation.
28086 This procedure does not insert a call for raising the exception because
28087 that is currently done by the run time.
28089 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
28091 * init.c: Add the global variable __gl_detect_blocking that indicates
28092 whether pragma Detect_Blocking is active (1) or not (0). Needed for

28097 pragma Detect_Blocking is active.
28099 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
28101 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
28102 DB is found in the ali file. Any unit compiled with pragma
28103 Detect_Blocking active forces its effect in the whole partition.
28105 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
28106 Detect_Blocking is active and delay is called from a protected
28109 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
28110 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
28111 Detect_Blocking is active (0 otherwise).
28112 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
28113 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
28116 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
28118 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
28119 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
28122 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
28123 (Register_Receiving_Stub): Add Subp_Info formal parameter.
28124 Update API in placeholder implemetation of s-parint to reflect changes
28125 in distribution runtime library.
28127 * sem_ch3.adb (Expand_Derived_Record): Rename to
28128 Expand_Record_Extension.
28130 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
28131 primitive operations of potentially distributed object types that have
28132 non-controlling anonymous access formals.
28134 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
28136 New implementation of expansion for remote access-to-subprogram types,
28137 based on the RACW infrastructure.
28138 This version of sem_dist is compatible with PolyORB/DSA as well as
28141 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
28142 Asynchrronous that applies to a remote access-to-subprogram type, mark
28143 the underlying RACW type as asynchronous.
28145 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
28146 __gnat_using_gnu_linker to 1.

28155 * exp_ch3.adb (Expand_Derived_Record): Rename to
28156 Expand_Record_Extension.
28157 (Build_Record_Init_Proc.Build_Assignment): The default expression in
28158 a component declaration must remain attached at that point in the
28159 tree so New_Copy_Tree copies it if the enclosing record type is derived.
28160 It is therefore necessary to take a copy of the expression when building
28161 the corresponding assignment statement in the init proc.
28162 As a side effect, in the case of a derived record type, we now see the
28163 original expression, without any rewriting that could have occurred
28164 during expansion of the ancestor type's init proc, and we do not need
28165 to go back to Original_Node.
28167 * exp_ch3.ads (Expand_Derived_Record): Rename to
28168 Expand_Record_Extension.
28170 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

28173 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
28174 New subprograms. Used to create a proxy tagged object for a remote
28175 subprogram. The proxy object is used as the designated object
28176 for RAS values on the same partition (unless All_Calls_Remote applies).
28177 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
28178 System.Partition_Interface.Get_Unique_Remote_Pointer.
28179 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
28180 Renamed from Add_RAS_*_Attribute.
28181 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
28183 New implementation of expansion for remote access-to-subprogram types,
28184 based on the RACW infrastructure.
28186 * exp_dist.ads (Copy_Specification): Update comment to note that this
28187 function can copy the specification from either a subprogram
28188 specification or an access-to-subprogram type definition.
28190 2004-09-09 Ed Schonberg <schonberg@gnat.com>
28192 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
28193 in an instance, between an explicit subprogram an one inherited from a
28194 type derived from an actual.
28196 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
28197 add a polling call if the subprogram is to be inlined by the back-end,
28198 to avoid repeated calls with multiple inlinings.
28200 * checks.adb (Apply_Alignment_Check): If the expression in the address
28201 clause is a call whose name is not a static entity (e.g. a dispatching
28202 call), treat as dynamic.
28204 2004-09-09 Robert Dewar <dewar@gnat.com>
28206 * g-trasym.ads: Minor reformatting
28208 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

28217 2004-09-09 Pascal Obry <obry@gnat.com>
28219 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
28220 enable map file generation. Add the right option to generate the map
28221 file if Map_File is set to True.
28223 * gnatdll.adb (Gen_Map_File): New variable.
28224 (Syntax): Add info about new -m (Map_File) option.
28225 (Parse_Command_Line): Add support for -m option.
28226 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

28242 2004-09-09 Cyrille Comar <comar@act-europe.fr>
28244 * opt.adb (Set_Opt_Config_Switches): Use Ada_Version_Runtime to compile
28247 * opt.ads: Add Ada_Version_Runtime constant used to decide which
28248 version of the language is used to compile the run time.
28250 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
28252 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
28253 of variable length temporaries for function return now that the
28254 back-end and gigi support it.

28305 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
28306 packed indexed component where array is an IN OUT formal. This
28307 generated garbage code previously.
28309 * gnat_ugn.texi: Document -fverbose-asm
28311 * gnat-style.texi: Minor updates (note that boolean constants and
28312 variables are joined with AND/OR rather than short circuit forms).

28326 expander is not active (but check for unset reference to prefix of
28329 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
28330 pragma Debug as an if statement with a constant condition, for
28331 consistent treatment of entity references contained within the
28332 enclosed procedure call.
28334 2004-09-01 Vincent Celier <celier@gnat.com>
28336 * bindgen.adb: (Set_EA_Last): New procedure
28337 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure
28339 (Gen_Adafinal_Ada): If no finalization, adafinal does nothing

28361 2004-09-01 Pascal Obry <obry@gnat.com>
28363 * gprcmd.adb (Extend): Do not output trailing directory separator. This
28364 is not needed and it confuses Windows GNU/make which does not report
28365 directory terminated by a slash as a directory.
28366 (gprcmd): Idem for "pwd" internal command.
28368 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
28369 target names rewrite to fix regressions with recent version of
28370 GNU/make. Starting with GNU/make 3.80 the pipe character was not
28371 handled properly anymore.

28421 2004-08-16 Pascal Obry <obry@gnat.com>
28423 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
28424 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
28425 option and not mdll anymore. Update comment.
28427 2004-08-16 Pascal Obry <obry@gnat.com>
28429 * bld.adb (Put_Include_Project): Properly handle directory separators
28432 2004-08-16 Ed Schonberg <schonberg@gnat.com>

28445 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
28447 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
28448 for a global aliased object with a variable size and an unconstrained
28449 nominal subtype, pretend there is no initializer if the one we have is
28450 incomplete, and avoid referencing an inexistant component in there. The
28451 part we have will be rebuilt anyway and the reference may confuse
28452 further operations.
28454 2004-08-13 Thomas Quinot <quinot@act-europe.fr>

28472 2004-08-13 Ed Schonberg <schonberg@gnat.com>
28474 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
28475 unit, this is an attempt to inline a construct that is not available in
28476 the current restricted mode, so abort rather than trying to continue.
28478 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
28479 discriminants that rename those of the parent, recover names of
28480 original discriminants for the constraint on the full view of the
28482 (Complete_Private_Subtype): Do not create a subtype declaration if the
28483 subtype is an itype.
28485 * gnat_rm.texi: Added section on implementation of discriminated
28486 records with default values for discriminants.
28488 2004-08-13 Ed Schonberg <schonberg@gnat.com>

28507 Change calls to GNAT.Sockets.Thin.Is_Socket_In_Set to account for
28508 new specification and test explicitly for non-zero return value.
28510 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
28511 returning C.int, to avoid using a derived boolean type.
28513 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
28514 Duplicate_Subexpr_No_Checks in preference to direct use of
28515 Remove_Side_Effects and New_Copy_Tree.

28539 2004-08-09 Olivier Hainque <hainque@act-europe.fr>
28541 * decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Adjust condition to
28542 ignore overflows on low and high bounds of an index to also account for
28543 differences in signedness between sizetype and gnu_index_subtype.
28544 These are as legitimate as the ones caused by a lower TYPE_PRECISION
28547 2004-08-09 Robert Dewar <dewar@gnat.com>
28549 * s-solita.ads, s-solita.adb: Minor reformatting
28551 * gnat_rm.texi: Add documentation for pragma Profile (Restricted)
28552 Move pragma Restricted_Run_Time, No_Run_Time, Ravenscar to new
28553 obsolescent section
28554 Add note that No_Implicit_Conditionals does not suppress
28555 run time constraint checks.
28557 * vms_conv.ads: Minor reformatting
28559 * s-secsta.adb: Use SS_Ptr instead of Mark_Id as stack pointer (cleanup
28560 and necessary for following change).
28561 (Mark): Return new format Mark_Id containing sec stack address
28562 (Release): Use sec stack address from Mark_Id avoiding Self call
28564 * s-secsta.ads: Define SS_Ptr to be used instead of Mark_Id as stack
28565 pointer (cleanup and necessary for following change).
28566 Define Mark_Id as record containing address of secondary stack, that way
28567 Release does not need to find the stack again, decreasing the number of
28568 calls to Self and improving efficiency.
28570 * sem_util.ads: Add a ??? comment for Is_Local_Variable_Reference
28572 * sem_ch5.adb (Analyze_Case_Statement): Add circuitry to track value of
28573 case variable into the individual case branches when possible.

31171 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
31172 overriding, use the operation of the parent unconditionally.
31174 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
31175 operation when either operand is a literal, to avoid further
31178 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and

32458 Analyze_Assignment to proceed.
32460 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
32461 complete assignment subtree which is now unnecessary, as the expansion
32462 of inlined call has been improved to preserve a consistent assignment
32463 tree. Note_Possible_Modification must be called only
32464 after checks have been applied, or else unnecessary checks will
32467 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
32468 of explicit dereferences that do not Come_From_Source:

32471 recorded as modifying the pointer);
32472 - do not rely on Original_Node being present (Analyze_Assignment
32473 calls Note_Possible_Modification on a copied tree).

32725 * osint.adb (Executable_Prefix): Set Exec_Name to the current
32726 executable name when not initialized. Otherwise, use its current value.
32728 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
32729 initialize it to another executable name than the current one. This
32730 allows to configure paths for an executable name (gnatmake) different
32731 from the current one (gnatdist).
32733 2004-03-29 Ed Schonberg <schonberg@gnat.com>
32735 * exp_ch6.adb (Expand_Call): A call to a function declared in the
32736 current unit cannot be inlined if it appears in the body of a withed
32737 unit, to avoid order of elaboration problems in gigi.
32739 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
32740 information for protected (wrapper) operation as well, to simplify gdb
32743 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

32782 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
32783 attribute reference does not denote a subtype, it can be any
32784 expression that has a classwide type, potentially after an implicit
32785 dereference. In particular, the prefix can be a view conversion for
32786 a classwide type (for which Is_Object_Reference holds), but it can
32787 also be a value conversion for an access-to-classwide type. In the
32788 latter case, there is an implicit dereference, and the original node
32789 for the prefix does not verify Is_Object_Reference.
32791 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
32792 conversion of a discriminant-dependent component of a mutable object
32795 2004-03-25 Ed Schonberg <schonberg@gnat.com>
32797 * freeze.adb (Freeze_Entity): When an inherited subprogram is
32798 inherited, has convention C, and has unconstrained array parameters,

32811 subprogram renaming comes from a defaulted formal subprogram in an

32816 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
32817 value expressions to ensure that calls within a component definition
32818 will be checked (since those are evaluated during the record type's

32870 declaration for a child subprogram body that acts as a spec, indicate
32871 that the entity in the declaration needs debugging information.
32873 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
32874 full view if the subtype is created for a constrained record component;
32875 gigi has enough information to construct the record, and there is no
32876 place in the tree for the declaration.
32878 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
32879 serial number for the dummy body that is built for analysis, to avoid

32917 Minor reformatting.
32919 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
32921 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
32922 as regular exception objects and not as mere integers representing the
32923 condition code. The latter approach required some dynamics to mask off
32924 severity bits, which did not fit well into the GCC table based model.
32925 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
32926 exception data objects. We don't it and it would conflict with the other
32927 external symbol we have to generate for such exceptions.
32929 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
32930 the special code for VMS exceptions, since these are now represented
32931 as regular exceptions objects.

32974 When needed (stack checking) the stack size is retrieved
32975 from the VxWorks kernel.
32977 * Makefile.in: Flag -nostdinc is required when building the run time
32978 for avoiding looking for files in the base compiler.
32979 Add the VxWorks specific version of the package body for
32980 System.Stack_checking.Operations (5zstchop.adb).

33225 explicit dereference.
33226 (Expand_N_Slice): Same. Always do the rewriting, even for the case
33227 of non-packed slices, since the dereference action generated by
33228 expansion of the explicit dereference is needed in any case.

33230 analyze and resolve the rewritten explicit dereference so it is seen
33232 (Insert_Dereference_Action): This procedure is now called only for the

34113 Don't make a bitfield if the field is to be addressable.

34115 checks for bitfield creation are triggered.
34116 (finish_record_type): During last pass over the fields, clear
34117 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

34597 importing constant atomic/volatile objects.
34598 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
34599 unless explicit Pure_Function pragma given, to avoid insidious bug of
34600 call to non-pure imported function getting eliminated.
34602 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb,
34603 gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,
34604 gnatxref.adb, gprcmd.adb, gprep.adb, make.adb: Minor reformatting

34618 New switch Sec_Stack_Used (GNAT, GNATBIND)
34619 Make Default_Secondary_Stack_Size a variable instead of a constant,
34620 so that it can be modified by the new -Dnnn bind switch.
34622 * rtsfind.adb (Load_Fail): Give full error message in configurable
34623 run-time mode if all_errors mode is set. This was not done in the case
34624 of a file not found, which was an oversight.
34625 Note if secondary stack unit is used by compiler.
34627 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
34628 ineffective elaborate all pragmas on non-visible packages (this
34629 happened when a renamed subprogram was called). Now the elaborate all
34630 always goes on the package containing the renaming rather than the one
34631 containing the renamed subprogram.
34633 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
34634 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
34636 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
34637 has an Etype that references an E_String_Literal.
34638 (Eval_String_Literal): Avoid assumption that N_String_Literal node
34639 always references an E_String_Literal_Subtype entity. This may not
34640 be true in the future.
34642 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
34645 * sem_res.adb (Resolve): Specialize msg for function name used in proc
34648 2004-01-05 Ed Falis <falis@gnat.com>

34653 2004-01-05 Vincent Celier <celier@gnat.com>
34655 * bld.adb: Minor comment updates
34656 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
34659 * make.adb (Gnatmake): Special process for files to compile/check when
34660 -B is specified. Fail when there are only foreign mains in attribute
34661 Main of the project file and -B is not specified. Do not skip bind/link
34662 steps when -B is specified.
34664 * makeusg.adb: Document new switch -B

34687 -gnatwa warning on static condition.
34689 2004-01-05 Doug Rupp <rupp@gnat.com>

34693 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
34695 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
34696 all attributes, including read-only attribute.

34707 based on the new naming scheme.
34709 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
34710 scheme for the shared runtime libraries.
34713 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
34715 (install-gnatlib): Do not create symlinks for shared libraries.
34716 (gnatlib-shared-default): Idem.
34717 (gnatlib-shared-dual-win32): New target. Not used for now as the
34718 auto-import feature does not support arrays/records.
34719 (gnatlib-shared-win32): Do not create copy for the shared libraries.
34720 (gnatlib-shared-vms): Fix shared runtime libraries names.
34722 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
34723 dependent runtime shared library name.
34725 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
34727 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
34730 2004-01-05 Ed Schonberg <schonberg@gnat.com>
34732 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
34733 protected objects when allocator has a subtype indication, not a
34734 qualified expression. Note that qualified expressions may have to be
34735 checked when limited aggregates are implemented.
34737 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
34738 pure, emit warning.
34739 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
34740 subprogram is imported, remove warning.
34742 2004-01-05 Geert Bosch <bosch@gnat.com>
34744 * s-poosiz.adb: Update copyright notice.
34745 (Allocate): Use Task_Lock to protect against concurrent access.

34784 * cstand.adb (Create_Standard): Change the way how the declaration of
34785 the Duration type is created (making it the same way as it is for all
34786 the other standard types).
34788 2003-12-17 Robert Dewar <dewar@gnat.com>
34790 * s-crtl.ads: Fix header format
34791 Change Pure to Preelaborate

34796 the expression type only if it is declared in the current unit.
34798 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
34799 are universal and already analyzed, as can occur in constrained
34800 subcomponents that depend on discriminants, when one constraint is a
34803 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
34804 type Any_Fixed is legal as the argument of a conversion, if only one
34805 fixed-point type is in context.

34816 2003-12-15 Vincent Celier <celier@gnat.com>
34818 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
34819 (Gnatchop): Do not set failure status when reporting the number of
34822 2003-12-15 Doug Rupp <rupp@gnat.com>

34844 * Make-lang.in: Makefile automatically updated
34846 2003-12-11 Ed Falis <falis@gnat.com>
34848 * 5zinit.adb: Clean up.
34850 * 5zintman.adb (Notify_Exception): replaced case statement with a call
34851 to __gnat_map_signal, imported from init.c to support
34852 signal -> exception mappings that depend on the vxWorks version.
34855 Created and exported __gnat_map_signal to support signal -> exception
34856 mapping that is dependent on the VxWorks version.
34857 Change mapping of SIGBUS from Program_Error to Storage_Error on VxWorks
34859 2003-12-11 Vasiliy Fofanv <fofanov@act-europe.fr>

34885 Minor reformatting throughout
34887 2003-12-11 Ed Schonberg <schonberg@gnat.com>
34889 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
34890 bounds of a loop, create a separate block in order to generate proper
34891 cleanup actions to prevent memory leaks.
34893 * sem_res.adb (Resolve_Call): After a call to
34894 Establish_Transient_Scope, the call may be rewritten and relocated, in
34895 which case no further processing is needed.

34907 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
34910 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
34913 2003-12-08 Robert Dewar <dewar@gnat.com>
34915 * 7sintman.adb: Minor reformatting
34917 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
34918 standard linker options to get standard libraries linked. We now plan
34919 to provide dummy versions of these libraries to match the appropriate
34920 configurable run-time (e.g. if a library is not needed at all, provide
34921 a dummy empty library).
34923 * targparm.ads: Configurable_Run_Time mode no longer affects linker
34924 options (-L parameters and standard libraries). What we plan to do is
34925 to provide dummy libraries where the libraries are not required.
34927 * gnatbind.adb: Minor comment improvement
34929 2003-12-08 Javier Miranda <miranda@gnat.com>
34931 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
34932 aggregate in the parent. Otherwise constants with limited aggregates
34933 are not supported. Add new formal to pass the component type (Ctype).
34934 It is required to call the corresponding IP subprogram in case of
34935 default initialized components.
34936 (Gen_Assign): In case of default-initialized component, generate a
34937 call to the IP subprogram associated with the component.
34938 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
34939 of aggregate with default initialized components.
34940 (Has_Default_Init_Comps): Improve implementation to recursively check
34941 all the present expressions.
34943 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
34944 to indicate that the initialization call corresponds to a
34945 default-initialized component of an aggregate.
34946 In case of default initialized aggregate with tasks this parameter is
34947 used to generate a null string (this is just a workaround that must be
34948 improved later). In case of discriminants, this parameter is used to
34949 generate a selected component node that gives access to the discriminant
34952 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
34953 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
34954 allocated aggregates with default-initialized components.
34956 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
34957 the box notation is used in positional aggregates.

34975 Set the scanner to return ends of line and comments as tokens, if
34976 Store_Comments is True.
34977 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
34978 comments are associated with these nodes. Store the node IDs in the
34980 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
34982 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
34983 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
34984 current project. Call Tree.Restore afterwards. Set the various nodes
34985 for comment storage (Next_End, End_Of_Line, Previous_Line,
34988 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
34989 defaulted to False.
34991 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
34992 to False. When Truncated is True, truncate the string, never go to the
34994 (Write_End_Of_Line_Comment): New procedure
34995 (Print): Process comments for nodes N_With_Clause,
34996 N_Package_Declaration, N_String_Type_Declaration,
34997 N_Attribute_Declaration, N_Typed_Variable_Declaration,
34998 N_Variable_Declaration, N_Case_Construction, N_Case_Item.
34999 Process nodes N_Comment.
35001 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
35002 without comments and there are some comments, set the flag
35003 Unkept_Comments to True.
35004 (Scan): If there are comments, set the flag Unkept_Comments to True and
35005 clear the comments.
35006 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
35007 (Next_End_Nodes: New table
35008 (Comment_Zones_Of): New function
35009 (Scan): New procedure; moved from Prj. Accumulate comments in the

35021 (End_Of_Line_Comment, Follows_Empty_Line,
35022 Is_Followed_By_Empty_Line): New functions

35024 (Set_First_Comment_Before, Set_First_Comment_Before_End): New procedures
35025 (Set_Next_Comment): New procedure
35026 (Default_Project_Node): Associate comment before if the node can store

35032 * scng.ads, scng.adb (Comment_Is_Token): New Boolean global variable,
35033 defaulted to False.
35034 (Scan): Store position of start of comment. If comments are tokens, set
35035 Comment_Id and set Token to Tok_Comment when scanning a comment.
35036 (Set_Comment_As_Token): New procedure
35038 * sinput-p.adb: Update Copyright notice
35039 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
35040 that no longer exists.
35042 2003-12-08 Javier Miranda <miranda@gnat.com>
35044 * sem_aggr.adb: Add dependence on Exp_Tss package
35045 Correct typo in comment
35046 (Resolve_Aggregate): In case of array aggregates set the estimated
35047 type of the aggregate before calling resolve. This is needed to know
35048 the name of the corresponding IP in case of limited array aggregates.
35049 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
35050 in case of default initialized array components.
35052 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited
35053 types. Required to give support to limited aggregates in generic
35056 2003-12-08 Ed Schonberg <schonberg@gnat.com>
35058 * sem_ch3.adb (Check_Initialization): For legality purposes, an
35059 inlined body functions like an instantiation.
35060 (Decimal_Fixed_Point_Declaration): Do not set kind of first subtype
35061 until bounds are analyzed, to diagnose premature use of type.
35063 * sem_util.adb (Wrong_Type): Improve error message when the type of
35064 the expression is used prematurely.
35066 2003-12-08 GNAT Script <nobody@gnat.com>
35068 * Make-lang.in: Makefile automatically updated
35070 2003-12-08 Arnaud Charlet <charlet@act-europe.fr>
35072 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
35073 they are automatically generated by Make-lang.in and cause nothing but
35074 maintenance troubles.
35076 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
35078 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

35087 Update copyright notice when appropriate.
35089 * 52osinte.ads, 5posinte.ads: Define a dummy value for the SA_SIGINFO
35092 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
35093 to ensure that the kernel fills in the interrupted context structure
35094 before calling a signal handler, which is necessary to be able to
35095 unwind past it. Update the copyright notice.
35097 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
35099 * a-elchha.ads: New file.
35101 * a-elchha.adb: New default last chance handler. Contents taken from
35102 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.
35104 * a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine
35105 is moved to a-elchha.adb to provide a target-independent default last
35108 * Makefile.rtl: Add a-elchha.o

36553 Remove the test against being in No_Run_Time_Mode before generating a
36554 call to Register_Tag. It is redundant with the test against the
36555 availability of the function Register_Tag.

38728 * misc.c (copy_lang_decl): Remove.
38730 2002-02-27 Zack Weinberg <zack@codesourcery.com>

38741 2002-01-30 Richard Henderson <rth@redhat.com>
38743 * trans.c (tree_transform) [N_Loop_Statement]: Use
38744 expand_exit_loop_top_cond.

38758 rule which was mandated by code generation issues.
38760 * gnat-style.texi (header): Add @dircategory, @direntry.
38761 (title page): Remove date.
38762 (general) Add @./@: where approriate, and two spaces after the
38763 full stop at the end of a sentence. Use @samp markup when
38764 referring concrete lexical entities (keywords, attribute names
38765 etc.), and @syntax for ARM grammar elements. Use @r for English
38766 text in comments. Use @emph for emphasis. Change "if-statements"
38767 etc. to "if statements" (without @samp). Break long lines. Make
38768 casing of section names consistent.
38769 (Identifiers): Use @samp markup for variable names.
38770 (Comments): Use @samp markup for comment characters. Line-end
38771 comments may follow any Ada code, not just statements. Fix
38772 misspelling of "Integer" as "integer".
38773 (Loop statements): Do not use variable name "I", use "J".

38781 function approach did not work well because of a side effect (the
38782 function call could reallocate the table which was being indexed
38783 using its result). Fixes ada/4851.

39150 2001-12-17 Laurent Pautet <pautet@gnat.com>
39153 Fix comment of Shutdown_Socket and Close_Socket. These functions
39154 should not fail silently because if they are called twice, this
39155 probably means that there is a race condition in the user program.
39156 Anyway, this behaviour is consistent with the rest of this unit.
39157 When an error occurs, an exception is raised with the error message
39158 as exception message.

40513 CRC using GNAT.CRC32.
40515 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
40516 now and not anymore a simple checksum.
40518 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
40521 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
40524 (Restore_Scan_State): rename Checksum to CRC.
40525 (Save_Scan_State): idem.
40529 (Checksum): rename to CRC.
40530 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
40532 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
40533 GNAT.CRC32). Update copyright notice.
40535 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
40536 GNAT.CRC32). Update copyright notice.
40539 (Accumulate_Checksum): removed.
40540 (Update): new procedure. Add a wide-character into the CRC.
40543 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
40544 (Load_File): fix initialization of S (change Source_Checksum to
40547 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
40548 Source_CRC in S initialization.
40550 * sinput.adb (Source_Checksum): renamed to Source_CRC.
40552 * sinput.ads (Source_Checksum): renamed to Source_CRC.
40553 Update comments for the CRC.
40555 * types.adb (Hex): Use lowercase for the letter part.
40557 * types.ads (Get_Hex_String): Returns the hexadecimal representation
40558 for a word. This is currently used only for CRC. In previous version,
40559 the checksum was using a representation with all letter being
40560 upper-case. With the new implementation (using CRC) we do not remove
40561 the 32th bit of the CRC, so we can have an upper-case starting letter
40562 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
40563 It is ambigous since the CRC was optional and could be followed by
40564 options like EB, EE. So now this routines uses lower-case letter for
40565 the hexadecimal representation. Strange enough only lower case letters
40566 where checked in Scan_ALI (even if this was not a possible case).
40568 * gnatvsn.ads (Library_Version): changed to 3.15a.
40570 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
40573 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version

40580 * ali-util.ads: Redo changes of previous revision to continue to use
40581 the word Checksum. Add 2001 to copyright notice.
40583 * ali.adb: Undo some of previous changes, not needed.
40584 Keep the change for lower case letters in the checksum.
40586 * ali.ads: Undo previous change not needed.
40588 * bcheck.adb: Undo most of previous change, not needed.
