1383 2008-05-20 Ed Schonberg <schonberg@adacore.com>
1386 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
1387 convention from its base type, do not set the type to that of integer,

1454 New local subprogram Is_Valid_Remote_Object_Type, replaces
1455 Is_Recursively_Limited_Private.

1460 as above for of RAS types and RCI subprograms. (The return type is not

1465 * sem_util.ads, sem_util.adb
1466 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
1467 Is_Remote_Call_Interface to identify RACW types in a stable and
1468 consistent way. We used to rely in this predicate on the privateness of
1469 the designated type and its ancestors, but depending on the currently
1470 visible private parts, this caused false negatives. We now uniformly
1471 rely on checks made at the point where the RACW type is declared.

1485 Add missing escaping of all-caps word 'CPP' in error messages.
1486 (Build_Discriminated_Subtype): Do not inherit representation clauses
1487 from parent type if subtype already carries them, because they are
1488 inherited earlier during derivation and already include those that may
1489 come from a partial view.
1491 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
1492 Check the declarations of a subprogram body for proper deferred

1527 operation of an RACW stub type (these primitives are only executed
1528 through dispatching, never through static calls).
1529 (Collect_Interps): When only one interpretation has been found, set N's
1530 Entity and Etype to that interpretation, otherwise Entity and Etype may
1531 still refer to an interpretation that was ignored by Add_One_Interp,
1532 in which case would end up with being marked as not overloaded but with
1533 an Entity attribute not pointing to its (unique) correct interpretation.
1535 2008-05-20 Ed Schonberg <schonberg@adacore.com>
1538 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

1592 equivalent representation, but has the advantage of allowing
1593 compilation of this file under 64 bits platforms.

5899 and those of the target interface primitive.
5900 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
5901 Timed_Entry_Call): Analyze the triggering statement as the first step of
5902 the processing. If this is a dispatching select, postpone the analysis
5903 of all select statements until the Expander transforms the select. This

5905 replicated some of the select statements. In case the Expander is
5906 disabled, perform regular analysis.
5907 (Check_Triggering_Statement): New routine.
5908 (Analyze_Requeue): Exclude any interpretations that are not entries when
5909 checking overloaded names in a requeue. Also test type conformance for

6506 in Xref_Entity_Record, which only supports a single instance of Tref_*,

6526 that handles use of 'Access and 'Unchecked_Access applied to

6616 2007-10-15 Gary Dismukes <dismukes@adacore.com>
6618 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
6619 association for an access component, add an association with null as
6620 the expression. Remove testing for array subtypes and the setting in
6621 that case of Ctyp to the array component type, which prevented proper
6622 inclusion of an association for null-initialized arrays. Collapse
6623 condition that tests for array subtypes into just a test of
6624 Is_Partially_Initialized_Type (which already covers arrays anyway).
6626 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>

6641 * sem_ch4.adb: Minor code and comment reformatting.
6642 (Analyze_Allocator): When the designated type of an unconstrained
6643 allocator is a record with unknown discriminants or an array with
6644 unknown range bounds, emit a detailed error message depending on the
6645 compilation mode and whether the designated type is limited.

6772 files instead of units to gigi.
6773 * gigi.h (struct File_Info_Type): New.
6774 (gigi): Rename and change type of number_units parameter, change
6775 type of file_info_ptr parameter.
6776 * trans.c (number_files): New global variable.
6777 (gigi): Rename and change type of number_units parameter, change
6778 type of file_info_ptr parameter.
6779 If mapped location support is enabled, create the isomorphic mapping
6780 between source files and line maps.
6781 (Sloc_to_locus): If mapped location support is enabled, translate
6782 source location into mapped location.
6783 (annotate_with_node): Rename into set_expr_location_from_node.

6809 * a-calend-vms.adb, a-calend.adb:
6810 Add a section on leap seconds control along with two entities used to
6811 enable and disable leap seconds support. The array Leap_Second_Times is
6812 now constant and contains hard time values pre-generated. Remove
6813 all elaboration code used to populate the table of leap seconds.
6816 Add entity Leap_Seconds_Support to the list of global run-time variables
6817 along with a comment on its usage and values.
6818 (Gen_Adainit_Ada): Add code to generate the declaration and import of
6819 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
6820 or one (enabled) depending on the presence of binder switch "-y".
6821 (Gen_Adainit_C): Add code to generate the declaration of external int
6822 __gl_leap_seconds_support. Set is value to zero (disabled) or one
6823 (enabled) depending on the presence of binder switch "-y".

6833 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
6835 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
6837 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
6838 function which can be called by the debugger to interrupt the tasks of
6839 an Ada application asynchronously, as needed on VxWorks.
6840 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
6842 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,

6873 2007-09-26 Javier Miranda <miranda@adacore.com>
6874 Eric Botcazou <ebotcazou@adacore.com>
6877 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
6878 indirection added to the HT_Link component of the TSD. This is required
6879 to statically allocate the TSD.
6882 Minor reordering of the declarations in the private part. Required to
6883 add a level of indirection to the contents of the TSD component HT_Link.
6884 This is required to statically allocate the TSD.
6886 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
6887 Is_Statically_Allocated set from constant objects.
6888 Do not make exported constants created by the compiler volatile.
6889 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
6892 * trans.c (Identifier_to_gnu): For constants, unshare initializers
6893 before returning them.
6895 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
6896 public part of the package.
6897 (Make_DT): Move HT_Link component out of the TSD record. For this
6898 purpose Make_DT now declares a separate object that stores the
6899 HT_Link value, and initializes the TSD component with the address
6900 of this new object. The addition of this level of indirection is
6901 required to statically allocate the TSD because the TSD cannot
6902 have variable components.
6903 (Expand_Interface_Conversion): Improve the expanded code.
6904 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
6906 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
6907 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
6908 if we are building static dispatch tables then we must not generate
6909 extra code to register the primitive because the dispatch table will
6910 be built at the end of the library package; otherwise we notify that
6911 we cannot build the static dispatch table.
6913 2007-09-26 Robert Dewar <dewar@adacore.com>
6915 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

6930 for thunks associated with interface types.
6932 * einfo.ads: Improve documentatation of Is_Internal
6933 (Is_Thunk): New attribute applicable to subprograms. True for thunks
6934 associated with interface types.
6935 Extensive comment fixes regarding flags that appear in all entities. The
6936 documentation is now consistent for all such flags (there were a number
6937 of errors in the documentation in this regard).
6939 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
6941 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
6942 of these procedures are passed a function call that already has
6943 build-in-place actuals (testing new flag
6944 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
6945 the case where processing continues.
6946 (Expand_Call): If the call is generated from a thunk body then we
6947 propagate the extra actuals associated with the accessibility
6948 level of the access type actuals.
6950 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
6951 of each extra formal of a protected operation to reference the
6952 corresponding extra formal of the subprogram denoted by the
6953 operation's Protected_Body_Subprogram.
6955 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
6956 N_Function_Call nodes.
6958 2007-09-26 Robert Dewar <dewar@adacore.com>
6960 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
6962 * debug.adb: Add d.s flag.
6964 2007-09-26 Gary Dismukes <dismukes@adacore.com>
6966 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
6967 debug variable so that it won't be initialized when pragma
6968 Initialize_Scalars is in effect.
6970 2007-09-26 Gary Dismukes <dismukes@adacore.com>
6972 * freeze.adb (Freeze_Entity): Remove check for preelaborable
6973 initialization of a full view. This is moved to
6974 Analyze_Package_Specification.
6976 * sem_ch7.adb (Analyze_Package_Specification): Add check for
6977 preelaborable initialization of a full view in entity loop.
6978 (Uninstall_Declarations): If entity is a use-visible compilation unit,
6979 its child units are use-visible only if they are visible child units.
6981 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
6982 whether an expression can be used within a type declaration that
6983 requires preelaborable init.
6984 (Check_Components): Replace inline code that does partial checking for
6985 preelaborable default expressions with call to
6986 Is_Preelaborable_Expression.
6987 (Has_Preelaborable_Initialization): In the case of a generic actual
6988 subtype, (that is, Is_Generic_Actual is True), return the result of
6989 applying Has_Preelaborable_Initialization to the generic actual's base
6992 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
6994 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
6995 call to Jan_1_Day _Of_Week to optimize its performance.
6996 (Is_Leap): Move the routine to the scope of Week_In_Year.
6997 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
6998 weekday on which January 1 falls of Year - 1 and Year + 1. This function
6999 avoids calling Time_Of and Split, thus making it more efficent.
7000 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
7002 * g-calend.ads (Week_In_Year): Change comment to reflect new
7005 2007-09-26 Emmanuel Briot <briot@adacore.com>
7007 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
7008 Command_Line): New types
7009 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
7010 support for defining how switches can be grouped on a command line (as
7011 is the case for -gnatw... for GNAT), and how simple switches can be
7012 used as aliases for more complex switches (-gnatwa is same as
7014 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
7015 (Start, Current_*): New subprograms
7016 Added support for parsing an array of strings in addition to the real
7018 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
7019 be moved from the body to the private part of the spec.
7020 (*): All subprograms now have an extra parameter with default value to
7021 specify which parser should be used. For backward compatibility, it
7022 defaults to parsing the command line of the application. They were also
7023 modified to properly handle cases where each of the argument does not
7024 start at index 1 (which is always true for Ada.Command_Line, but not
7025 when processing any Argument_List).
7026 (Free): New subprogram
7027 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
7028 Argument): New subprograms
7029 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
7030 special characters like ':', '=',... are now handled in a single place,
7031 which makes the code more extensible eventually.
7032 (Getopt, Full_Switch): When the switch was returned as part of the
7033 special character '*', make sure it is prepended by the switch character
7034 ('-' in general), so that the application knows whether "foo" or "-foo"
7035 was specified on the command line.
7037 2007-09-26 Florian Villoing <villoing@adacore.com>
7039 * g-dirope.adb (Remove_Dir): In case we are removing directories
7040 recursively, make sure that if an exception is raised during the
7041 processing, the current working directory is reset to its initial
7042 value before propagating the exception.
7044 2007-09-26 Vincent Celier <celier@adacore.com>
7046 * gnatbind.adb: If there are several ALI files specified and there is
7047 a main program to bind, the first ALI is expected to contain the main
7048 subprogram and the names of the binder generated files will be derived
7049 from the first ALI file name.
7050 (Gnatbind): Fix insertion character in invocation of Error_Msg
7052 2007-09-26 Vincent Celier <celier@adacore.com>
7054 * gnatcmd.adb (Check_Files): Do not include sources that have been
7055 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
7057 2007-09-26 Ed Schonberg <schonberg@adacore.com>
7059 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
7060 information about each of its index types, following the type
7061 reference for its component type.
7063 2007-09-26 Vincent Celier <celier@adacore.com>
7065 * make.adb: (Kill): New procedure (__gnat_kill imported)
7066 (Running_Compile, Outstanding_Compiles): Global variables that
7067 were previously local to procedure Compile_Sources.
7068 (Sigint_Intercepted): Send signal SIGINT to all outstanding
7069 compilation processes.
7071 (Gnatmake): If project files are used, create the mapping of all the
7072 sources, so that the correct paths will be found.
7074 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
7076 2007-09-26 Vincent Celier <celier@adacore.com>
7078 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
7080 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
7081 Replace components Compiler_Min_Options and Binder_Min_Options with
7082 Compiler_Required_Switches and Binder_Required_Switches in record
7084 Remove components Default_Language and Config in Project_Tree_Data,
7087 * prj-attr.adb: New attributes Required_Switches (<language>) in
7088 packages Compiler and Binder.
7090 * prj-nmsc.adb: Major rewrite of the processing of configuration
7091 attributes for gprbuild. No impact on GNAT tools.
7093 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
7094 process configuration attributes: this is done in Prj.Nmsc.Check.

7096 being extended, instead of a shallow copy.
7097 (Process_Project_Tree_Phase_1): New procedure

7099 (Process): Implementation now uses the two new procedures
7101 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
7102 from the project config, not the tree config that no longer exists.
7104 2007-09-26 Vincent Celier <celier@adacore.com>

7117 message to cite use of <> in aggregate component associations rather
7118 than wrongly indicating use of limited aggregates.

7122 * sem_attr.adb (Analyze_Access_Attribute): Fix missing set of
7125 2007-09-26 Ed Schonberg <schonberg@adacore.com>
7127 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
7128 ancestor of the derived type, the operations are inherited from the
7129 primary dispatch table of the parent.
7130 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
7131 when the context is an explicit type conversion.
7133 2007-09-26 Ed Schonberg <schonberg@adacore.com>
7135 * sem_ch4.adb (Analyze_Qualified_Expression): Apply name resolution

7433 potentially be called.
7434 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
7435 body for 'Output when the type is abstract (only the creation of the
7436 body for 'Input is excluded when the type is abstract).

7438 statement, so that False will be returned for TTS_Stream_Input if the
7439 associated tagged type is an abstract extension. Add comments for

7442 variable, insert init proc call only after the shared variable
7443 procedures have been processed, because the IP call needs to undergo
7444 shared passive variable reference expansion, which requires these
7445 procedures to be available (and elaborated).

7457 type, retrieve its value from the aggregate itself, where it must have
7460 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
7461 to remove other spurious ambiguities on arithmetic operations involving
7462 literals and addresses, on systems where Address is a visible integer
7463 type, when the operator is called in functional notation.
7464 (Try_Primitive_Operation): Within an instance, a call in prefixed form
7465 is legal when the types match, even if the operation is currently
7468 2007-09-10 Ed Schonberg <schonberg@adacore.com>
7470 * sem_ch12.adb (Build_Local_Package): A formal package with no
7471 associations is legal if all formals have defaults. It is not

7504 * decl.c (gnat_to_gnu_entity) <Object>: Simplify the condition under

7506 * trans.c (lvalue_required_p) <N_Slice>: New case, extracted from
7507 the N_Indexed_Component case.

7590 (Write_Entity_Flags): Write the status of flag Is_Raised.
7591 (Is_Descendent_Of_Address): New entity flag, to simplify handling of

7613 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
7614 library-level package renaming, pass the declaration associated with
7615 the renaming's special debug variable to Qualify_Entity_Names to ensure

7618 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
7619 occurring in the list of entities to qualify, and do not attempt to
7620 traverse an entity list in that case. Variables associated with
7621 ` library-level package renamings can now occur in the table.

7647 avoid very deep recursion in the front end, which was causing stack
7650 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
7651 string, and the right operand is a string literal (the case of "" &
7652 "..."), optimize by avoiding copying the right operand -- just use the
7653 value of the right operand directly.
7655 * stringt.adb (Store_String_Chars): Optimize by growing the
7656 String_Chars table all at once, rather than appending characters one by
7658 (Write_String_Table_Entry): If the string to be printed is very long,
7659 just print the first few characters, followed by the length. Otherwise,
7660 doing "pn(n)" in the debugger can take an extremely long time.
7662 * sem_prag.adb (Process_Interface_Name): Replace loop doing

7682 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
7683 flag, for effiency. It is called when analyzing arithmetic operators
7684 and also for actuals in calls that are universal_integers. The flag is
7685 set for the predefined type address, and for any type or subtype

7758 associated with Standard_Debug_Renaming_Type, to be used as the type of
7759 the special variables whose names provide debugger encodings for
7760 renaming declarations.
7762 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.

7770 (Debug_Renaming_Declaration): Replace creation of an enumeration type
7771 and literal with creation of a variable of type
7772 Standard_Debug_Renaming_Type whose name encodes both the renamed object
7773 and the entity of the renaming declaration.
7774 (Qualify_Entity_Name): Add the delayed qualification of the entity name
7775 part of the name of a variable that has a Debug_Renaming_Link.

7782 Ed Schonberg <schonberg@adacore.com>
7783 Javier Miranda <miranda@adacore.com>
7785 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
7786 ancestor part given by an aggregate to test for an unchecked conversion,
7787 since this can occur in some cases when the ancestor part is a function
7788 call, and we don't want to fall into the recursive call to this
7789 procedure in that case.
7791 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
7792 stream attributes on limited types to account for user-specified
7793 attributes as well as whether Input (resp. Output) becomes available
7794 due to Read (resp. Write) being available for the type. Change Boolean
7795 variable to the more accurate name
7796 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
7797 double-"not" predicate at beginning of return statement to more
7798 understandable form.
7800 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
7801 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
7802 in a block statement and use that as the first statement of the
7803 expanded return rather than incorrectly using the handled sequence as
7804 the first statement.
7806 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
7807 operation, generate an explicit freeze node for it rather than
7808 generating extra formals, to ensure that gigi has the proper order of
7809 elaboration for anonymous subtypes in the signature of the subprograms.
7810 (Build_In_Place_Formal): Move assertion to beginning of loop.
7811 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
7812 applied to a function call (occurs for some cases of 'Input).
7813 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
7814 applied to a function call (occurs for some cases of 'Input).
7816 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
7817 2005, generate an extended return statement enclosing the result object
7820 * freeze.adb (Freeze_Record_Type): Extend the current management of
7821 components that are access type with an allocator as default value: add
7822 missing support to the use of qualified expressions of the
7823 allocator (which also cause freezing of the designated type!)
7824 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
7825 dispatching operation, since extra formals may be needed by calls to
7826 build-in-place functions (such as stream 'Input).
7828 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
7829 formals for 'Constrained and accessibility level in the case of a
7830 predefined dispatching operation.
7832 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
7833 point, no need to find the parent node.
7835 2007-08-16 Javier Miranda <miranda@adacore.com>
7837 * exp_attr.adb (Attribute_Priority): Add missing support for entries
7840 2007-08-16 Javier Miranda <miranda@adacore.com>
7842 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
7843 is not really required and can introduce regression with the debugger.
7844 The original problem is fixed with the patch written for checks.adb.
7846 2007-08-16 Thomas Quinot <quinot@adacore.com>
7848 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

7856 Including_Non_Switch set to False.
7858 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
7859 parameter Including_Non_Switch, defaulted to True. When
7860 Including_Non_Switch is False, options that are not switches and
7861 appear as relative path are not converted to absolute paths.

7873 currently inspected is a selected component, retrieve the entity of
7875 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
7876 from the immediate ancestor of Main_Unit_Entity.
7877 (Install_Limited_Withed_Unit): Do not install the limited view of
7878 package P if P is reachable through an ancestor chain from package C
7879 and C also has a with clause for P in its body.
7880 (Has_Limited_With_Clause): New routine.
7881 (Has_With_Clause): New routine.
7883 2007-08-16 Ed Schonberg <schonberg@adacore.com>
7885 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
7886 generic for an enclosing instance is a global reference, even though
7887 its scope is the enclosing instance.
7889 2007-08-16 Gary Dismukes <dismukes@adacore.com>
7890 Javier Miranda <miranda@adacore.com>
7892 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to

7906 implements an operation inherited from a progenitor interface, verify
7907 that they are subtype-conformant.

7910 Bob Duff <duff@adacore.com>
7911 Nicolas Setton <setton@adacore.com>
7913 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
7914 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
7915 the statement which is being resolved comes from a predefined library
7916 unit, all non-predefined library interpretations are skipped.
7917 (Resolve_Op_Concat): If string concatenation was folded in the parser,
7918 but the "&" is user defined, give an error, because the folding would
7921 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
7922 the parser has folded a long sequence of concatenations of string
7925 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
7926 and "JMP_BUF" variables as artificial.
7927 (N_String_Literal): Do not use alloca for very long string literals. Use
7928 xmalloc/free instead. Otherwise the stack might overflow.

7973 Ed Schonberg <schonberg@adacore.com>
7975 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
7976 Suppress unmodified in-out parameter warning in some cases
7977 This patch is a also fairly significant change to the way suppressible
7980 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
7981 needed for access to concurrent record types generated by the expander.
7982 (Generate_Range_Check): When generating a temporary to capture the
7983 value of a conversion that requires a range check, set the type of the
7984 temporary before rewriting the node, so that the type is always
7985 properly placed for back-end use.
7986 (Apply_Float_Conversion_Check): Handle case where the conversion is
7988 (Get_Discriminal): Code reformatting. Climb the scope stack looking
7989 for a protected type in order to examine its discriminants.

8001 (Get_Allocator_Final_List): For the case of an anonymous access type
8002 that has a specified Associated_Final_Chain, do not go up to the
8004 (Expand_N_Type_Conversion): Test for the case of renamings of access
8005 parameters when deciding whether to apply a run-time accessibility
8007 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
8008 aggregate code before allocator, and ahead of declaration for
8009 temporary, to prevent access before elaboration when the allocator is
8010 an actual for an access parameter.
8011 (Expand_N_Type_Conversion): On an access type conversion involving an
8012 access parameter, do not apply an accessibility check when the
8013 operand's original node was an attribute other than 'Access. We now
8014 create access conversions for the expansion of 'Unchecked_Access and
8015 'Unrestricted_Access in certain cases and clearly accessibility should
8016 not be checked for those.
8018 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
8019 includes a type conversion of a packed component that has been expanded,
8020 recover the original expression for the object, and use this expression
8021 in the post-call assignment statement, so that the assignment is made
8022 to the object and not to a back-end temporary.
8023 (Freeze_Subprogram): In case of primitives of tagged types not defined
8024 at the library level force generation of code to register the primitive
8025 in the dispatch table. In addition some code reorganization has been
8026 done to leave the implementation clear.
8027 (Expand_Call): When expanding an inherited implicit conversion,
8028 preserve the type of the inherited function after the intrinsic
8029 operation has been expanded.
8031 * exp_ch2.ads, exp_ch2.adb
8032 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
8033 of an entry formal appearing in an assignment statement does not assign
8035 (Expand_Current_Value): Instead of calling a routine to determine
8036 whether the prefix of an attribute reference should be optimized or
8037 not, prevent the optimization of such prefixes all together.
8039 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
8040 component whose prefix is known to be of an access type is an implicit
8041 dereference and does not assign to the prefix.

8049 Add comments and correct harmless error in Build_NCT_Hash_Tables
8050 (Array_Aggr_Subtype): Associate each itype created for an index type to
8051 the corresponding range construct, and not to the aggregate itself. to

8053 node, to prevent errors when complex expression is copied.
8054 Fix mishandling of multiple levels of parens
8056 * sem_aggr.adb: Create a limited view of an incomplete type, to make
8057 treatment of limited views uniform for all visible declarations in a
8058 limited_withed package.
8059 (New_Copy_Tree): If hash table is being used and itype is visited,
8060 make an entry into table to link associated node and new itype.
8061 (Resolve_Record_Aggregate): Do not add an others box association for a
8062 discriminated record component that has only discriminants, when there
8063 is a box association for the component itself.

8113 generation of a freezing node to ensure proper management of null
8114 excluding access types in the backend.
8115 (Create_Extra_Formals): Test base type of the formal when checking for
8116 the need to add an extra accessibility-level formal. Pass the entity E
8117 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
8118 originally being done in a couple of cases), to ensure that the
8119 Extra_Formals list gets set on the entity E when the first entity is
8121 (Conforming_Types): Add missing calls to Base_Type to the code that
8122 handles anonymous access types. This is required to handle the
8123 general case because Process_Formals builds internal subtype entities
8124 to handle null-excluding access types.
8125 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
8126 functions that need it, even when not marked Requires_Overriding.
8127 Improve warnings for in out parameters
8128 (Analyze_Function_Return): Warn for disallowed null return
8129 Warn on return from procedure with unset out parameter
8130 Ensure consistent use of # in error messages
8131 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
8132 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
8133 the implicit conversion of the expression done for anonymous access
8134 types. This is required to generate the code of the null excluding
8135 check (if required).
8137 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
8138 A formal parameter is never publicly referenceable outside of its body.
8139 (Check_References): For an unreferenced formal parameter in an accept
8140 statement, use the same warning circuitry as for subprogram formal
8142 (Warn_On_Unreferenced_Entity): New subprogram, taken from
8143 Output_Unreferenced_Messages, containing the part of that routine that
8144 is now reused for entry formals as described above.
8145 (Goto_Spec_Entity): New function
8146 (Check_References): Do not give IN OUT warning for dispatching operation
8147 Improve warnings for in out parameters
8148 (Test_Ref): Check that the entity is not undefinite before calling
8149 Scope_Within, in order to avoid infinite loops.
8150 Warn on return from procedure with unset out parameter
8151 Improved warnings for unused variables

8154 Javier Miranda <miranda@adacore.com>
8155 Gary Dismukes <dismukes@adacore.com>
8157 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
8158 (Expand_N_Attribute_Reference): Further unify the handling of the
8159 three forms of access attributes, using common code now for all three
8160 cases. Add a test for the case of applying an access attribute to
8161 an explicit dereference when the context is an access-to-interface
8162 type. In that case we need to apply the conversion to the prefix
8163 of the explicit dereference rather than the prefix of the attribute.
8164 (Attribute_Version, UET_Address): Set entity as internal to ensure
8165 proper dg output of implicit importation.
8166 (Expand_Access_To_Type): Removed.
8167 (Expand_N_Attribute_Reference): Merge the code from the three cases
8168 of access attributes, since the processing is largely identical for
8169 these cases. The substantive fix here is to process the case of a
8170 type name prefix (current instance case) before handling the case
8171 of interface prefixes.

8175 Javier Miranda <miranda@adacore.com>
8176 Robert Dewar <dewar@adacore.com>
8178 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
8179 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
8180 type that is an anonymous access to controlled object, establish
8181 an associated finalization chain to avoid corrupting the global
8182 finalization list when a dynamically allocated object designated
8183 by such a component is deallocated.
8184 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
8185 functions that need it, even when not marked Requires_Overriding.
8186 (Initialize_Tag): Replace call to has_discriminants by call to
8187 Is_Variable_Size_Record in the circuitry that handles the
8188 initialization of secondary tags.

8190 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
8191 Suppress_Initialization pragma for a derived type.
8192 (Is_Variable_Size_Record): New subprogram.
8193 (Build_Offset_To_Top_Functions): New implementation that simplifies the
8194 initial version of this routine and also fixes problems causing
8195 incomplete initialization of the table of interfaces.
8196 (Build_Init_Procedure): Improve the generation of code to initialize the
8197 the tag components of secondary dispatch tables.
8198 (Init_Secondary_Tags): New implementation that simplifies the previous
8199 version of this routine.

8203 diagnose attemps to freeze a subprogram when some untagged type of its
8204 profile is a private type whose full view has not been analyzed yet.
8205 (Freeze_Array_Type): Generate init proc for packed array if either
8206 Initialize or Normalize_Scalars is set.
8207 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
8208 constructing the new profile, copy the null_exclusion indicator for each
8209 parameter, to ensure full conformance of the new body with the spec.
8211 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
8212 Create wrappers for constructor functions that need it, even when not
8213 marked Requires_Overriding.
8214 (Covers): Handle properly designated types of anonymous access types,
8215 whose non-limited views are themselves incomplete types.
8216 (Add_Entry): Use an entity to store the abstract operation which hides
8218 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.

8226 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
8227 (Write_Overloads): Output the abstract operator if present.
8228 (Add_Entry): Before inserting a new entry into the interpretation table
8229 for a node, determine whether the entry will be disabled by an abstract
8231 (Binary_Op_Interp_May_Be_Hidden): New routine.
8232 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
8234 (Function_Interp_May_Be_Hidden): New routine.
8235 (Has_Compatible_Type): Do not consider interpretations hidden by

8243 Javier Miranda <miranda@adacore.com>
8245 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
8246 types declared in the declarative part of a nested package body or in
8247 the proper body of a stub.

8253 output of implicit importation and exportation.
8254 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
8255 first formal of the thunk is always associated with the controlling
8256 type. In addition perform the following code cleanup: remove formal
8257 Thunk_Alias which is no longer required, cleanup evaluation of the
8258 the controlling type, and update the documentation.
8259 Replace occurrence of Default_Prim_Op_Count by
8260 Max_Predef_Prims. Addition of compile-time check to verify
8261 that the value of Max_Predef_Prims is correct.
8262 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
8263 (Make_DT): Add parameter to indicate when type has been frozen by an

8266 construction of statically allocated dispatch tables.
8267 (Make_DT): In case of library-level tagged types export the declaration
8268 of the primary tag. Remove generation of tags (now done by Make_Tags).
8269 Additional modifications to handle non-static generation of dispatch
8270 tables. Take care of building tables for asynchronous interface types
8271 (Make_Tags): New subprogram that generates the entities associated with
8272 the primary and secondary tags of Typ and fills the contents of Access_
8273 Disp_Table. In case of library-level tagged types imports the forward
8274 declaration of the primary tag that will be declared later by Make_DT.
8275 (Expand_Interface_Conversion): In case of access types to interfaces
8276 replace an itype declaration by an explicit type declaration to avoid
8277 problems associated with the scope of such itype in transient blocks.
8279 2007-08-14 Robert Dewar <dewar@adacore.com>
8280 Ed Schonberg <schonberg@adacore.com>
8281 Javier Miranda <miranda@adacore.com>
8283 * exp_util.ads, exp_util.adb:
8284 This patch replaces a number of occurrences of explicit tests for N_Null
8285 with calls to Known_Null. This improves tracking of null values, since
8286 Known_Null also catches null constants, and variables currently known to
8287 be null, so we get better tracking.
8288 (Ensure_Defined): create an itype reference only in the scope of the
8290 (Side_Effect_Free): A selected component of an access type that
8291 denotes a component with a rep clause must be treated as not
8292 side-effect free, because if it is part of a linked structure its
8293 value may be affected by a renaming.
8294 (Expand_Subtype_From_Expr): For limited objects initialized with build
8295 in place function calls, do nothing; otherwise we prematurely introduce
8296 an N_Reference node in the expression initializing the object, which
8297 breaks the circuitry that detects and adds the additional arguments to
8298 the called function. Bug found working in the new patch for statically
8299 allocated dispatch tables.
8300 (Is_Library_Level_Tagged_Type): New subprogram.
8301 (Remove_Side_Effects): If the expression of an elementary type is an
8302 operator treat as a function call.
8303 (Make_Literal_Range): If the index type of the array is not integer, use
8304 attributes properly to compute the constraint on the resulting aggregate
8307 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
8308 class-wide type whose base type is an incomplete private type, leave
8309 class-wide type unfrozen so that freeze nodes can be generated
8310 properly at a later point.
8311 (Freeze_Entity, array case): Handle case of pragma Pack and component
8312 size attributre clause for same array.

8372 source dirs are not known.
8373 (Check_Ada_Name): Allow all identifiers that are not reserved words
8375 Major update of the Project Manager and of the project aware tools,
8376 including gprmake, so that the same sources in the GNAT repository

8990 type, the candidate operations are found in the scope of declaration of
8991 the type, because the type has no primitive subprograms.

8993 a private extension, only examine visible components before trying to
8994 analyze as a prefixed call.

10209 bounds of the slice to construct the required constraint checks.
10210 Improve NOT NULL error messages
10211 (Apply_Constraint_Check): If the context is a null-excluding access

10228 Arnaud Charlet <charlet@adacore.com>
10230 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
10231 applicable to types that have the With_Type flag set. Returns the
10232 non-limited view of the type, if available, otherwise the type itself.
10233 For class-wide types, there is no direct link in the tree, so we have
10234 to retrieve the class-wide type of the non-limited view of the Etype.
10235 New attributes Static_Initialization and Static_Elaboration_Desired.
10236 Remove the pragma Thread_Body, and the associated flag
10237 Is_Thread_Body in entities, and all related code.

10247 components of records. Set to point to the entity of the corresponding
10249 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
10250 (Original_Access_Type): Remove, not needed.
10251 (Root_Type): Handle properly subtypes of class-wide-types.
10254 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
10255 class-wide types visible through limited-with clauses.
10256 (Try_Primitive_Operation): When examining all primitive operations of a
10257 tagged type, do not consider subprograms labeled as hidden unless they
10258 belong to a private generic type with a tagged parent.
10259 (Try_Object_Operation): Extensive rewriting, to handle properly various
10260 overloading cases, when several ancestors may have class-wide operations
10261 that are possible candidates, and when the overloaded functions return
10262 array types and have defaulted parameters so that the call may be
10263 interpreted as an indexing.
10264 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
10265 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
10266 successive actuals before analyzing the call itself.
10267 (Try_Primitive_Operation): A primitive operation is compatible with the
10268 prefix if the prefix has a synchronized type and the type of the formal
10269 is its corresponding record, as can be the case when the primitive
10270 operation is declared outside of the body of the type.
10271 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
10272 perform homonym traversal, looking for class-wide operation matches
10273 (formerly done in statements of Try_Class_Wide_Operation). Matches on
10274 access parameters are now restricted to anonymous access types.
10275 (Mark_Allocator): An allocator with a discriminant association parent is
10277 (Try_One_Prefix_Interpretation): If the type of the object is
10278 incomplete, as can be happen when it is a limited view obtained through
10279 a limited_with_clause, the selected component is not part of a prefixed
10281 (Complete_Object_Operation): Diagnose properly an object that is not
10282 aliased when the corresponding controlling formal is an access
10284 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
10285 ambiguous calls in prefixed notation, where two primitives differ only
10286 in that the controlling argument of one is an access parameter.
10288 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
10289 whether a function that returns an unconstrained type can be inlined.
10290 (Process_Formals): Diagnose properly the illegal use of an incomplete
10291 type in the profile of an access_to_subprogram declaration.
10292 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
10293 operations are attached to the corresponding record.
10294 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
10295 When processing a primitive of a concurrent type which implements an
10296 interface change the type of all controlling formals to that of the
10297 corresponding record type.
10298 (Check_Synchronized_Overriding): Relax the conditional logic when trying
10299 to determine the tagged type to which a primitive belongs.
10300 (Check_Conventions): Capture condition to ignore a primitive operation
10301 (which is shared between the loop in Check_Conventions and the one in
10302 Check_Convention) in a new local function Skip_Check.
10303 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
10304 confusion with Check_Conventions' own Prim_Op local variable.
10305 (Create_Extra_Formals): Test for a tagged result type rather than a
10306 controlling result when determining whether to add a BIP_Alloc_Form
10307 formal and a BIP_Final_List formal to the function.
10308 (Check_Conformance); For parameters that are anonymous access types,
10309 subtype conformance requires that the not null and the constant
10310 indicators must match
10311 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
10312 to retrieve the appropriate type when processing a concurrent type
10313 declared within a generic. Minor comment reformatting. Change invocation
10314 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
10316 (Analyze_Subprogram_Body): If the return type of a function is an
10317 anonymous access to the limited view of a class-wide type, and the
10318 non-limited view of the type is available, update the type of the
10319 function so that code can be generated.
10320 (Process_Formals): In case of access-subtype itype whose designated
10321 type is also an itype (situation that happens now with access to
10322 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
10323 attribute to avoid backend problems.
10324 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
10325 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
10326 anonymous types' designated types are same before testing
10327 Subtypes_Statically_Match.
10328 (Create_Extra_Formals): Test for a named access parameter that is a
10329 controlling formal as an additional condition for adding an
10330 accessibility level formal. This can occur in the subp type created for
10331 dispatching calls in Expand_Dispatching_Call, and allows calling
10332 Create_Extra_Formals from that procedure rather than special-casing the
10333 extra formals there.
10334 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
10335 when the function has a controlling result.
10336 (Check_Returns): Add much more knowledge of the optimization of local
10337 raise statements to gotos, to retain proper warnings in this case.
10338 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
10339 nodes when looking for last statement.
10341 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
10342 class-wide types visible through limited with clauses.
10343 (Add_One_Interp): If the operands are anonymous access types, the
10344 predefined operator on universal_access is immediately visibles
10345 (Find_Unique_Type): Handle anonymous access to subprogram types just as
10346 other anonymous access types.
10347 (Disambiguate): Take into account CIL convention.
10348 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
10350 2007-06-06 Robert Dewar <dewar@adacore.com>
10352 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
10353 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
10354 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
10355 Fix lower bound of tables.
10358 * nlists.adb: Ditto.
10359 (Prev_Node, Next_Node): Change index type to Int so that it properly
10360 covers the range First_Node_Id - 1 up.
10362 2007-06-06 Javier Miranda <miranda@adacore.com>
10363 Ed Schonberg <schonberg@adacore.com>
10364 Bob Duff <duff@adacore.com>
10365 Hristian Kirtchev <kirtchev@adacore.com>
10367 * exp_aggr.ads, exp_aggr.adb:
10368 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
10369 in extension aggregates.
10370 (Flatten): Other conditions being met, an aggregate is static if the
10371 low bound given by component associations is different from the low
10372 bound of the base index type.
10373 (Packed_Array_Aggregate_Handled): If the component type is itself a
10374 packed array or record, the front-end must expand into assignments.
10375 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
10376 Init_Pr, instead of Ancestor_Is_Expression.
10377 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
10378 coextension chain root, either generate a list controller or use the
10379 already existing one.
10380 (Static_Array_Aggregate): New procedure to construct a positional
10381 aggregate that can be handled by the backend, when all bounds and
10382 components are compile-time known constants.
10383 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
10384 types covering interface types into assignments.
10385 (Replace_Type): move to Build_Record_Aggr_Code.
10386 (Expand_Record_Aggr_Code): if the target of the aggregate is an
10387 interface type, convert to the definite type of the aggregate itself,
10388 so that needed components are visible.
10389 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
10390 components and the context is an extended return statement do not
10391 create a transient block for it, to prevent premature finalization
10392 before the return is executed.
10393 (Gen_Assign): Do not generate a call to deep adjust routine if the
10394 component type is itself an array of controlled (sub)-components
10395 initialized with an inner aggregate.
10396 (Component_Check): New name for Static_Check. This name is now more
10397 appropriate, and documentation is added which was missing.
10398 (Component_Check): Add test for bit aligned component value
10399 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
10400 Tagged_Comps, name is more appropriate given added function below.
10401 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

10404 Javier Miranda <miranda@adacore.com>
10405 Robert Dewar <dewar@adacore.com>
10407 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
10408 Terminated: Add unchecked type conversion from System.Address to
10409 System.Tasking.Task_Id when calling the predefined primitive
10411 Disable new Ada 05 accessibility check for JVM.NET targets, which
10412 cannot be implemented in a practical way.
10413 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
10414 the sources always references the tag of the actual object. Therefore,
10415 if 'Tag is applied in the sources to class-wide interface objects we
10416 generate code that displaces "this" to reference the base of the object.
10417 (Expand_N_Attribute_Reference, case Size): Return specified size if
10418 known to front end.
10419 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
10420 has code that displaces the pointer of the object to manage interface
10421 types. However this code must not be executed when the prefix is a
10422 subprogram. This bug caused the wrong expansion of the internally
10423 generated assignment that fills the dispatch table when the primitive
10424 is a function returning a class-wide interface type.
10425 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
10426 Set_Attribute_Name for Name_Unaligned_Valid.
10428 2007-06-06 Ed Schonberg <schonberg@adacore.com>
10429 Gary Dismukes <dismukes@adacore.com>
10431 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
10432 If the initialization is the equivalent aggregate of the initialization
10433 procedure of the type, do not remove it.
10434 (Expand_N_Attribute_Definition_Clause): Exclude access variables
10435 initialized to null from having their expression reset to empty and
10436 note this exception in the comment.

10440 Ed Schonberg <schonberg@adacore.com>
10441 Gary Dismukes <dismukes@adacore.com>
10443 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
10444 Add "with" and "use" clauses for Sem_Attr.
10445 (Expand_Current_Value): Do not replace occurences of attribute
10446 references where the prefix must be a simple name.
10448 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
10449 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
10450 Attribute_Requires_Simple_Name_Prefix.
10451 (Name_Modifies_Prefix): Body of new function.
10452 (Requires_Simple_Name_Prefix): Body of new function.
10453 (Resolve_Attribute, case Access): Improve error message for case of
10454 mismatched conventions.
10455 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
10457 (Analyze_Attribute, case 'Access): If the type of the prefix is a
10458 constrained subtype for a nominal unconstrained type, use its base type
10459 to check for conformance with the context.
10460 (Resolve_Attribute): Remove test of the access type being associated
10461 with a return statement from condition for performing accessibility
10462 checks on access attributes, since this case is now captured by
10463 Is_Local_Anonymous_Access.
10464 (Analyze_Access_Attribute): Set Address_Taken on entity
10465 (Analyze_Attribute, case Address): Set Address_Taken on entity
10466 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
10467 validating an access attribute whose prefix is a current instance.
10468 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
10469 applied to dispatching operations, if freezing is required then we set
10470 the attribute Has_Delayed_Freeze in the prefix's entity.
10471 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
10472 current scope if access of local subprogram taken
10473 (Analyze_Access_Attribute): Check legality of self-reference even if the
10474 expression comes from source, as when a single component association in
10475 an aggregate has a box association.
10476 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
10477 the prefix if it is a protected operation and the attribute is
10478 Unrestricted_Access.
10479 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
10480 reference to the base type of the context, to force a constraint check
10481 when the context is an access subtype with an explicit constraint.
10482 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
10483 node is rewritten as an interface conversion. leave unanalyzed after
10484 resolution, to ensure that type checking against the context will take

10488 Javier Miranda <miranda@adacore.com>
10489 Robert Dewar <dewar@adacore.com>
10491 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
10492 wrapper when the full view of the controlling type of an inherited
10493 function that dispatches on result implements interfaces.
10494 (Expand_N_Object_Declaration): In cases where the type of the
10495 declaration is anonymous access, create finalization list for it.
10496 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
10497 if the object has no explicit initialization, to match description of
10498 functionality of pragam Persistent_BSS.
10499 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
10500 new function to build static aggregates, to replace initialization call
10501 when static initialization is desired.
10502 (Freeze_Type): Generate a list controller for an access type whenever
10503 its designated type has controlled anonymous access discriminants.
10504 (Build_Equivalent_Aggregate): New procedure to compute a static
10505 aggregate to be used as default initialization for composite types,
10506 instead of a generating a call to the initialization procedure for the
10508 (Build_Initialization_Call): When available, replace a call to the
10509 initialization procedure with a copy of the equivalent static aggregate
10511 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
10512 declarations for objects of a class-wide interface type, rather than
10513 just identifiers, to prevent visibility problems.
10514 (Expand_N_Object_Declaration): When expanding the declaration for an
10515 object of a class-wide interface type, preserve the homonym chain of
10516 the original entity before exchanging it with that of the generated
10517 renaming declaration.
10518 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
10519 active, because there is no way to handle the exception.
10520 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
10521 to do a minimum decoration of the Access_Disp_Table list.
10522 (Expand_Record_Controller): Avoid the addition of the controller between
10523 the component containing the tag of a secondary dispatch table and its
10524 adjacent component that stores the offset to the base of the object.
10525 This latter component is only generated when the parent type has
10526 discriminants ---documented in Add_Interface_Tag_Components).
10527 (Apply_Array_Size_Check): Removed, no longer needed.
10528 (Expand_N_Full_Type_Declaration): If the type has anonymous access
10529 components, create a Master_Entity for it only if it contains tasks.
10530 (Build_Init_Procedure): Suppress the tag assignment compiling under
10532 (Freeze_Record_Type): Remove code associated with creation of dispatch
10534 (Init_Secondary_Tags): Update type of actuals when generating calls to
10535 Ada.Tags.Set_Offset_To_Top
10536 (Stream_Operation_OK): Disable use of streams compiling under no
10538 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
10539 if Has_Init_Expression set.
10540 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
10541 Register_Primitive, which provides the same functionality.
10542 (Requires_Init_Proc): Return false in case of interface types.
10543 (Add_Secondary_Tables): Use the new attribute Related_Interface to
10545 (Predefined_Primitive_Freeze): Do not assume that an internal entity
10546 is always associated with a predefined primitive because the internal
10547 entities associated with interface types are not predefined primitives.
10548 Therefore, the call to Is_Internal is replaced by a call to the
10549 function Is_Predefined_Dispatching_Operation.
10550 (Make_Eq_If): When generating the list of comparisons for the
10551 components of a given variant, omit the controller component that is
10552 present if the variant has controlled components.
10554 2007-06-06 Javier Miranda <miranda@adacore.com>
10555 Hristian Kirtchev <kirtchev@adacore.com>
10556 Bob Duff <duff@adacore.com>
10558 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
10559 handle the creation of finalization lists and calls for nested
10560 coextensions when the root of the chains is part of a return statement.
10561 (Inside_A_Return_Statement): New function inside Complete_Coextension_
10563 (Expand_Record_Equality): Skip components that are interface types.
10564 (Displace_Allocator_Pointer): Add missing support for interface subtypes
10565 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
10566 with Rewrite_Coextension. Change the condition for detecting coextension
10568 (Is_Local_Access_Discriminant): Removed.
10569 (Rewrite_Coextension): New routine which rewrites a static coextension
10570 as a temporary and uses its unrestricted access in the construction of
10572 (Complete_Coextension_Finalization): New routine. Generate finalization
10573 attachment calls to all delayed coextensions.
10574 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
10575 the allocator is not a coextension itself and has delayed coextensions.
10576 If the current allocator is controlled, but also a coextension, delay
10577 the generation of the finalization attachment call.
10578 Rename local variable "Node" to "Nod" in order to avoid confusion with
10580 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
10581 limited types that are not inherently limited. Such an allocator is
10582 illegal, but is generated by the expander for a return statement, to
10583 copy the result onto the secondary stack. This is the only case where a
10584 limited object can be copied. Generate code to displace the pointer
10585 to the object if the qualified expression is a class-wide interface
10586 object. Such displacement was missing and hence the copy of the object
10588 (Apply_Accessibility_Check): Handle allocated objects initialized in
10590 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
10591 and Expand_Allocator_Expression. Allocating class-wide interface objects
10592 this routine displaces the pointer to the allocated object to reference
10593 the component referencing the corresponding secondary dispatch table.
10594 Expand_Allocator_Expression): Add missing support to allocate class-wide
10595 interface objects initialized with a qualified expression.
10596 (Get_Allocator_Final_List): Test for an anonymous access type that is a
10597 function result type, and use the finalization list associated with the
10598 function scope in that case (such an anonymous type should not be
10599 treated like an access parameter's type).
10601 2007-06-06 Ed Schonberg <schonberg@adacore.com>
10602 Gary Dismukes <dismukes@adacore.com>
10603 Javier Miranda <miranda@adacore.com>
10605 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
10606 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
10607 required exception handler.
10608 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
10609 properly the case of a function whose return type is a limited
10610 class-wide interface type. Modify the code of the accessibility
10611 check to handle class-wide interface objects. In this case we need to
10612 displace "this" to reference the primary dispatch table to get access
10613 to the TSD of the object (to evaluate its accessibility level).
10614 (Expand_N_Extended_Return_Statement): Test for a tagged result type
10615 rather than a controlling result as one of the conditions for
10616 generating tests of the implicit BIP_Alloc_Form formal. The
10617 initialization assignment is also handled according to whether the
10618 result is tagged instead of controlling.
10619 In the case where the init assignment is inserted in the "then" part of
10620 the allocation conditional, rewrite the target to be a dereference of
10621 the implicit BIP_Object_Access formal.
10622 If the returned value is unconstrained and created on the secondary
10623 stack, mark the enclosing block and function so that the secondary
10624 stack is not reclaimed on return.
10625 Treat returns from functions with controlling results similarly to
10626 returns from functions with unconstrained result subtypes.
10627 If the object returned is unconstrained, and an allocator must be
10628 created for it, analyze the allocator once the block for the extended
10629 return is installed, to ensure that finalizable components
10630 of the expression use the proper finalization list. Guard the call to
10631 Move_Final_List with a check that there is something to finalize.
10632 (Make_Tag_Ctrl_Assignment): Use "old" handling
10633 of controlled type assignment for virtual machines, since new code uses
10634 unsupported features (such as direct access to bytes in memory).
10636 2007-06-06 Gary Dismukes <dismukes@adacore.com>
10637 Ed Schonberg <schonberg@adacore.com>
10639 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
10640 accessibility actual, check for the case of an aliased object that has
10641 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
10642 we fall into processing for the attribute rather than the name of the
10644 (Expand_Inline_Call): If an actual is a literal, and the corresponding
10645 formal has its address taken in the body, create a temporary to capture
10646 value. If the return type is a limited interface, do not treat the
10647 return value as Controlled.
10648 (Is_In_Place_Function): If the return type is a limited interface,
10649 treat as returning in place. The actual returned object may not always
10650 be limited, but the caller has to assume that it is returned in place.
10651 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
10652 context of an allocator, use the correct finalization chain (that is,
10653 the chain belonging to the access type, rather than the chain belonging
10654 to the current scope).
10655 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
10656 result type rather than a controlling result as a precondition for
10657 adding an allocation form actual to a build-in-place call.
10658 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
10659 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
10660 primitive in the dispatch tables. This work is now done by Make_DT when
10661 the type is frozen.
10662 (Register_Predefined_DT_Entry): Removed.
10663 (Add_Return): If end label is not present, use sloc of last statement
10664 for generated return statement in procedure, for better gdb behavior
10666 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
10667 object address nodes to ensure proper processing by routines like
10669 (Expand_Call): Fix generation of validity check for parameter
10670 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
10671 the allocation form parameter if the result subtype is constrained,
10672 except when the function has a controlling result.
10673 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
10674 rather than Is_Controlled and Has_Controlled_Component, since we want to
10675 include class-wide result types in this treatment. Also test for a
10676 controlling result, since that also requires passing a finalization
10678 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
10679 even when the result subtype is constrained, to handle calls involving
10680 controlling results.
10681 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
10682 is now called even when the result subtype is constrained, to handle
10683 calls involving controlling results.
10684 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
10685 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
10686 now performs the test).
10687 (Make_Build_In_Place_Call_In_Object_Declaration):
10688 Add_Alloc_Form_Actual_* is now called even when the result subtype is
10689 constrained, to handle calls involving controlling results.
10690 (Add_Return): Accomodate rewritten pattern from local raise to goto
10691 transformation, so that we still recognize an transfer statement
10692 and do the right thing here in that case.
10693 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
10694 and end of subprogram code.
10695 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
10696 support for primitives that are functions (without formals) with a
10697 controlling result.
10698 (Inherited_From_Formal): If the actual subtype has not generic parent
10699 type, it is not an actual for a formal derived type, and there is no
10700 operation to inherit from the formal.

10703 Thomas Quinot <quinot@adacore.com>
10705 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
10706 inserted cleanup code appropriately for GDB use.
10707 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
10708 exception handler for Deep_Adjust or Deep_Finalize.
10709 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
10710 Raise_From_Controlled_Operation is available, use a call to that
10711 subprogram instead of a plain "raise Program_Error" node to raise
10712 Program_Error if an exception is propagated from an Adjust or Finalize
10714 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
10715 appears in the optional statement list of a triggering alternative, the
10716 scope actions can be inserted directly there, and not in the list that
10717 includes the asynchronous select itself.

10723 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
10724 generated exception handler appropriately when debugging generated code.
10725 Deal properly with No_Exception_Propagation restriction mode.
10726 (Expand_N_Abort_Statement): Add an unchecked type conversion from
10727 System.Address to System.Tasking.Task_Id when processing the result of
10728 the predefined primitive _disp_get_task_id.
10729 (Expand_N_Asynchronous_Select): Clarify comment.
10730 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
10731 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
10732 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
10733 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
10734 privals and for generated call to Complete_Entry_Body, for better gdb
10736 (Copy_Result_Type): Utility to construct a parameter and result profile
10737 for protected functions whose return type is an anonymous access to
10739 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
10741 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
10742 point when the local-raise-to-goto transformation has taken place.

10745 Nicolas Setton <setton@adacore.com>
10747 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
10748 functionality when the backend is generating code.
10749 Otherwise any serious error
10750 reported by the backend calling the frontend routine Error_Msg
10751 changes the Compilation_Mode to Check_Semantics, disables the
10752 functionality of this routine and causes the generation of
10753 spureous additional errors.
10755 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
10756 debugging information now generated by the compiler for fat-pointer

10894 (Side_Effect_Free): An expression that is the renaming of an object or
10895 whose prefix is the renaming of a object, is not side-effect free

12605 associated with either the Equivalent or Root type, instead of the
12607 (gnat_to_gnu_entity): Manually mark the top of the DECL_FIELD_OFFSET
12608 subtree for every field of a global record type.

12626 (E_Return_Statement): This node type has the Finalization_Chain_Entity
12627 attribute, in case the result type has controlled parts.
12628 (Requires_Overriding): Add this new flag, because "requires
12629 overriding" is subtly different from "is abstract" (see AI-228).
12630 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
12631 Is_Abstract_Type. Make sure these are called only when appropriate.

12693 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
12694 "abstract subprograms must be visible" message, whether or not the type
12695 is an interface; that is, remove the special case for interface types.

12721 build-in-place functions with result type with controlled parts.
12722 Remove no longer used entities.
12724 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
12725 longer needed, because the full type is now limited, and therefore a

12758 to handle properly the anonymous access case.
12760 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
12761 for all access attributes, because overload resolution should work the
12762 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This

12772 attempt to derive from a synchronized tagged type.
12773 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
12774 type, inherit the class-wide type already created, because it may
12775 already have been used in a self-referential anonymous access component.
12776 (Mentions_T): Recognize self-referential anonymous access components
12777 that use (a subtype of) the class-wide type of the enclosing type.
12778 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
12779 Derived_Type for Prev formal on call to
12780 Check_Anonymous_Access_Components rather than Empty.
12781 (Make_Incomplete_Type_Declaration): Add test for case where the type has
12782 a record extension in deciding whether to create a class-wide type,

12799 with abstract interfaces.
12800 (Analyze_Subtype_Indication): Resolve the range with the given subtype

12828 (Compile_Sources): Do nothing, not even check if the source is up to
12829 date, if its project is externally built.
12830 (Compile): When compiling a predefined source, add -gnatpg
12831 as the second switch, after -c.
12832 (Compile_Sources): Allow compilation of Annex J renames without -a
12833 (Is_In_Object_Directory): Check if the ALI file is in the object

12836 gnatbind if the ALI file effectively exists.
12837 (Initialize): Add the directory where gnatmake is invoked in front of
12838 the path if it is invoked from a bin directory, even without directory
12839 information, so that the correct GNAT tools will be used when spawned

12863 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
12864 when -gnatg is not specified.
12865 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
12866 there is no need to generate always a record_definition_node in case
12867 of synchronized interface types.
12868 (SIS_Entry_Active): Initialize global variable to False

12894 (Convert_Aggr_In_Allocator): If the allocator is for an access
12895 discriminant and the type is controlled. do not place on a finalization
12896 list at this point. The proper list will be determined from the

12916 parameter of the containing subprogram.
12917 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
12918 under No_Dispatching_Calls restriction. During the semantic analysis
12919 we already notified such violation.

12937 initialize most the TSD components by means of an aggregate.
12938 Modify the declaration of the object containing the TSD
12939 because we now expand code that has a higher level of abstraction.
12940 The TSD has a discriminant containing the Inheritance Depth Level,
12941 value that is used in the membership test but also to fix the size
12942 of the table of ancestors.
12943 (Expand_Interface_Conversion): Insert function body at the closest place
12944 to the conversion expression, to prevent access-before-elaboration

12998 specify Any_Limited_Interface, and this functionality is already
12999 provided by the function Has_Abstract_Interfaces.
13000 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
13001 support concurrent types implementing interfaces.
13002 (Find_Implemented_Interface): Removed. All the calls to this subprogram
13003 specify kind Any_Limited_Interface, and this functionality is already
13004 provided by the function Has_Abstract_Interfaces.
13005 (Remove_Side_Effects): replace Controlled_Type by
13006 CW_Or_Controlled_Type whenever the issue is related to
13007 using or not the secondary stack.
13009 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
13010 P_Interface_Type_Definition to fulfill the new interface (the formal
13011 Is_Synchronized is no longer required).

13020 Cyrille Comar <comar@adacore.com>
13022 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
13023 anonymous, use finalization list of enclosing dynamic scope.
13024 (Expand_N_Package_Declaration): For a library package declaration
13025 without a corresponding body, generate RACW subprogram bodies in the
13026 spec (just as we do for the task activation call).
13027 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
13028 Is_Abstract_Type. Make sure these are called only when appropriate.
13029 Remove all code for DSP option
13030 (CW_Or_Controlled_Type): new subprogram.
13032 2007-04-06 Eric Botcazou <botcazou@adacore.com>
13033 Ed Schonberg <schonberg@adacore.com>
13034 Gary Dismukes <dismukes@adacore.com>
13036 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
13037 parameter. If it is set to true, return a result capped according to
13038 the global upper bound for the index of an entry family.
13039 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
13040 (Build_Find_Body_Index): Adjust for above change.
13041 (Entry_Index_Expression): Likewise.
13042 (Is_Potentially_Large_Family): New function extracted from...
13043 (Collect_Entry_Families): ...here. Call it to detect whether the family
13044 is potentially large.
13045 (Build_Entry_Count_Expression): If the family is potentially large, call
13046 Family_Size with 'Cap' set to true.
13047 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
13048 a protected version of an operation declared in the private part of
13049 a protected object, because they may be invoked through a callback.
13050 (Set_Privals): If the type of a private component is an anonymous access
13051 type, do not create a new itype for each protected body.
13052 If the body of a protected operation creates
13053 controlled types (including allocators for class-widetypes), the
13054 body of the corresponding protected subprogram must include a
13056 (Build_Activation_Chain_Entity): Build the chain entity for extended
13058 (Type_Conformant_Parameters): Use common predicate Conforming_Types
13059 to determine whether operation overrides an inherited primitive.
13060 (Build_Wrapper_Spec): Add code to examine the parents while looking
13061 for a possible overriding candidate.
13062 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
13063 hold an actual parameter value since its initialization is separated
13064 from the the declaration. Prevents errors on null-excluding access
13067 2007-04-06 Thomas Quinot <quinot@adacore.com>
13068 Pablo Oliveira <oliveira@adacore.com>
13070 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
13071 Do an Unchecked_Conversion to handle the passage from the Underlying
13072 Type to the Base Type when calling Build_To_Any_Call and
13073 Build_From_Any_Call.
13074 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
13075 E_Constant, depending upon Variable formal.
13076 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13077 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
13078 parameter that requires an extra constrained parameter, declare
13079 temporary for actual as a variable, not a constant.
13080 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
13081 the unit being compiled is the one that contains the stub type.
13082 Change primitive operation name for the RACW associated with a RAS
13083 from Call to _Call so it cannot clash with any legal identifier.
13084 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
13086 (Append_RACW_Bodies): New subprogram.
13087 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
13088 Add_Receiving_Stubs_To_Declarations functions.
13089 When expanding a package body, this list correspond to the
13090 statements in the HSS at the end of the pacakge.
13091 When expanding a package spec, this list correspond to the
13093 (Add_Receiving_Stubs_To_Declarations): Append the function
13094 registering the receiving stubs at the end of the 'Stmts' list.
13095 (RCI_Package_Locator): Pass the new Version generic formal when
13096 instantiating a RCI_Locator package.
13097 (Build_From_Any_Function): To compute the High bound for an
13098 unconstrained array actual, we add the Low bound with the length.
13099 Thus we must convert the low bound and the length to an appropriate
13100 type before doing the sum.
13101 (Build_Subprogram_Receiving_Stubs, PolyORB):
13102 * Retrieve the extra formals parameters at the
13103 end of the parameter stream.
13104 * Use Move_Any_Value to write back out parameters
13105 after executing the request as it is more efficient
13106 than Copy_Any_Value.
13107 * Build the any containing Extra Formals with the
13108 appropriate typecode.
13109 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
13110 empty Component_List.
13111 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
13112 the tree the declaration for an object that serves as actual parameter
13113 in server-side stubs.
13114 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13115 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13116 Use Build_Actual_Object_Declaration to prepare the actuals.

13118 Extra Constrained Parameters.
13119 (Build_General_Calling_Stubs): Set the parameter type to boolean for
13120 Extra Constrained parameters.
13121 (Build_To_Any_Function, Build_From_Any_Function,
13122 Built_TypeCode_Function): When Typ is implicit, call the correct
13123 function with the first not implicit parent type.
13124 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
13125 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
13126 typecode from the Etype. Therefore we retrieve the correct typecode
13127 with a call to Get_Any_Type.
13128 (Copy_Specification): Do controlling formal type substitution based on
13129 Is_Controlling_Formal flag, instead of caller-provided object type.
13130 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
13131 a RACW primitive operation, we might get a subprogram declaration for an
13132 ancestor of the RACW designated type (not for the designated type
13133 itself), in the case where this operation is inherited. In this case we
13134 have no easy means of determining the original tagged type for which
13135 the primitive was declared, so instead we now rely on
13136 Copy_Specification to use the Is_Controlling_Formal flag to determine
13137 which formals require type substitution.

13143 GNAT.Current_Exception are not allowed if pragma Restrictions
13144 (No_Exception_Propagation) is set and in any case make the associated
13145 handler unsuitable as a target for a local raise statement.
13146 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
13147 run-time subprogram CW_Membership by call to Build_CW_Membership.
13148 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
13149 by a function call, a temporary must be created before expanding the
13150 Constructor_Call itself, to prevent out-of-order elaboration in the
13151 back-end when stack checking is enabled..
13153 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13155 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
13156 result are the bounds of the left operand, not the right.
13158 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13161 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use
13162 discriminant defaults.

13173 box corresponds to a component of the type.
13174 (Resolve_Record_Aggregate): Split Is_Abstract flag into

13227 to be checked by gnatstack, which are the naming and the stack packages.
13228 (Check_Files): If no .ci files were specified for gnatstack we add all
13229 the .ci files belonging to the projects, including binder generated
13231 (Non_VMS_Usage): Document that gnatstack accept project file switches.
13232 (GNATCmd): Update the B_Start variable if we are in a VMS environment.
13233 Add gnatstack to the list of commands that use project file related
13234 switches, and get the single attribute Switches from the stack package
13235 in a project file when calling gnatstack. Parse the -U flag for
13236 processing files belonging to all projects in the project tree.

13278 * mingw32.h (S2WSU): New macro to convert from a string to a
13279 wide-string using the UTF-8 encoding. The S2WS macro supports now only
13280 standard 8bits encoding.
13281 (WS2SU): As above but converting from wide-sring to string.
13282 This is needed as it is necessary to have access to both versions in the
13283 runtime for the form parameter encoding support.
13284 This set of patch add support for the encoding form parameter.
13285 (S2WS): Improve implementation to handle cases where the filename is not
13286 UTF-8 encoded. In this case we default to using the current code page
13287 for the conversion.

13299 corresponding encoding value into AFCB structure.
13300 (Reset): Pass the encoding value to freopen.
13301 (Close): Move the call to Lock_Task to the beginning of the procedure.

13334 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
13335 __gnat_adjust_context_for_raise.
13336 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
13337 implementation of floating point operations as native x86 targets.
13338 So the FPU should be initialized in the same way using finit. Fix
13339 floating point operations accuracy issues.
13340 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
13341 member in struct sigaction, so as to avoid warning for incompatible

13357 Javier Miranda <miranda@adacore.com>
13359 * lib-xref.ads, lib-xref.adb:
13360 Modify the loop that collects type references, to include interface
13361 types that the type implements. List each of these interfaces when
13362 building the entry for the type.
13363 (Generate_Definition): Initialize component Def and Typ of new entry
13364 in table Xrefs, to avoid to have these components unitialized.

13408 2007-04-06 Robert Dewar <dewar@adacore.com>
13410 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
13411 it no longer destroys the contents of Name_Buffer or Name_Len and
13412 non-standard and invalid names are handled better.

13427 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
13428 illegal in Ada 95, in cases where it is legal. Change the warnings to
13429 errors in other cases. Don't give the error unless the "not null"
13430 parses properly. Correct the source position at which the error occurs.
13431 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
13432 P_Null_Exclusion, to suppress "not null" warnings.

13482 Library_Builder, Local_Config_File, Objects_Path, Objects_Path_File,
13483 Run_Path_Option, Toolchain_Version.
13484 Entry for pragma Unreferenced_Objects
13486 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD

13508 the default project path, initially done during elaboration of the
13510 If the prefix returned by Sdefault is null, get the prefix from a call
13511 to Executable_Prefix_Path.
13512 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
13515 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
13516 canonical directory name to open the directory from which files are
13518 (Record_Other_Sources): Idem.
13519 (Locate_Directory): Add the possibility to create automatically missing
13520 directories when Setup_Projects is True.
13521 Call Locate_Directory so that the directory will be created when
13522 Setup_Projects is True, for object dir, library dir, library ALI dir,
13523 library source copy dir and exec dir.
13525 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
13528 2007-04-06 Robert Dewar <dewar@adacore.com>
13530 * sem_ch13.ads, sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):

13539 Is_Abstract_Subprogram and Is_Abstract_Type.
13540 (Adjust_Record_For_Reverse_Bit_Order): New procedure
13542 * repinfo.adb (List_Record_Info): Use First/
13543 Next_Component_Or_Discriminant.
13545 * style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
13548 * stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch
13549 Include -gnatyA in default switches

13562 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
13563 full word is no longer compared twice.
13565 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13567 * sem_ch10.adb (Install_Limited_Context_Clauses.
13568 Expand_Limited_With_Clause): Use a new copy of selector name in the
13569 call to Make_With_Clause. This fixes the tree structure for ASIS
13570 purposes. Nothing is changed in the compiler behaviour.
13571 (Process_Body_Clauses): Handle properly use clauses whose prefix is
13572 a package renaming.
13573 (Install_Limited_With_Clauses): Do not install non-limited view when it
13574 is still incomplete.
13576 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13577 Gary Dismukes <dismukes@adacore.com>
13579 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
13580 when capturing size information, instead of base type, which for a
13581 formal array type will be the unconstrained type.
13582 (Analyze_Formal_Object_Declaration): Add check for illegal default
13583 expressions for a formal in object of a limited type.
13584 (Instantiate_Object): Ditto.
13585 (Check_Formal_Package_Instance): Skip entities that are formal objects,
13586 because they were defaulted in the formal package and no check applies
13588 (Check_Formal_Package_Instance): Extend conformance check to other
13589 discrete types beyond Integer.
13590 (Process_Default): Copy directly the unmatched formal. A generic copy
13591 has already been performed in Analyze_Formal_Package.
13592 (Analyze_Associations): If a formal subprogram has no match, check for
13593 partial parametrization before looking for a default, to prevent
13595 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
13596 not set the instantiation environment before analyzing the actuals.
13597 Fixes regression on 8515-003 with implementation of AI-133.
13598 Set_Instance_Env checks whether the generic unit is a predefined
13599 unit, in which case the instance must be analyzed with the latest Ada
13600 mode. This setting must take place after analysis of the actuals,
13601 because the actuals must be analyzed and frozen in the Ada mode extant
13602 outside of the current instantiation.
13603 (Save_Env, Restore_Env): Preserve and restore the configuration
13604 parameters so that predefined units can be compiled in the proper Ada
13606 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
13607 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
13608 and Is_Abstract_Type.
13609 (Analyze_Formal_Package): For better error recovery, Add exception
13610 handler to catch Instantion_Error, which can be raised in
13611 Analyze_Associations
13613 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13614 Bob Duff <duff@adacore.com>
13615 Gary Dismukes <dismukes@adacore.com>
13617 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
13618 prefix type is a discriminated subtype of the type of the formal.
13619 (Analyze_Allocator): Collect all coextensions regardless of the context.
13620 Whether they can be allocated statically is determined in exp_ch4.
13621 (Analyze_Selected_Component): If the prefix is a limited view and the
13622 non-limited view is available, use the non-limited one.
13623 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
13624 therefore illegal), suggest a qualified expression rather than a type
13625 conversion, because a type conversion would be illegal in this context.
13626 (Anayze_Allocator): Trace recursively all nested allocators so that all
13627 coextensions are on the corresponding list for the root. Do no mark
13628 coextensions if the root allocator is within a declaration for a stack-
13629 allocated object, because the access discriminants will be allocated on
13631 (Analyze_Call): Remove restriction on calls to limited functions for the
13632 cases of generic actuals for formal objects, defaults for formal objects
13633 and defaults for record components.
13634 (Analyze_Allocator): Before analysis, chain coextensions on the proper
13635 element list. Their expansion is delayed until the enclosing allocator
13636 is processed and its finalization list constructed.
13637 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
13638 for an operation with the given name among the primitive operations of
13639 the corresponding record type.
13640 (Analyze_Selected_Component): If the prefix is a task type that
13641 implements an interface, and there is no entry with the given name,
13642 check whether there is another primitive operation (e.g. a function)
13644 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
13645 properly the indexing of a function call written in prefix form, where
13646 the function returns an array type, and all parameters of the function
13647 except the first have defaults.
13648 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
13649 the original operands, rather than relocating them, for efficiency and
13650 to work properly when an operand is overloaded.
13651 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
13652 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
13653 (Analyze_Selected_Component): If the prefix is a private extension, only
13654 scan the visible components, not those of the full view.
13655 (Try_Primitive_Operation): If the operation is a procedure, collect all
13656 possible interpretations, as for a function, because in the presence of
13657 classwide parameters several primitive operations of the type can match
13658 the given arguments.
13660 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13661 Robert Dewar <dewar@adacore.com>
13663 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
13664 tag-indeterminate call to an abstract function, when the left-hand side
13666 (Analyze_Loop_Statement): Improve detection of infinite loops
13668 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13669 Thomas Quinot <quinot@adacore.com>
13671 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
13672 out of Analyze_Package_Declaration, because processing must be applied
13673 to package bodies as well, for deferred constants completed by pragmas.
13674 (Analyze_Package_Declaration): When the package declaration being
13675 analyzed does not require an explicit body, call Check_Completion.
13676 (May_Need_Implicit_Body): An implicit body is required when a package
13677 spec contains the declaration of a remote access-to-classwide type.
13678 (Analyze_Package_Body): If the package contains RACWs, append the
13679 pending subprogram bodies generated by exp_dist at the end of the body.
13680 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
13681 Is_Abstract_Subprogram and Is_Abstract_Type.
13682 (Preserve_Full_Attributes): The full entity list is not an attribute
13683 that must be preserved from full to partial view.
13685 * sem_dist.adb (Add_RAS_Dereference_TSS):
13686 Change primitive name to _Call so it cannot clash with any legal
13687 identifier, and be special-cased in Check_Completion.
13688 Mark the full view of the designated type for the RACW associated with
13689 a RAS as Comes_From_Source to get proper view switching when installing
13690 private declarations.
13691 Provite a placeholder nested package body along with the nested spec
13692 to have a place for Append_RACW_Bodies to generate the calling stubs
13693 and stream attributes.
13695 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13696 Robert Dewar <dewar@adacore.com>
13698 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
13699 that is a limited view, check the non-limited view if available.
13700 (Undefined): Refine error message for missing with of Text_IO
13701 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
13702 to distinguish real missing with cases.
13703 Fix format of all missing with messages
13704 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
13705 renaming as body when renamed entity is abstract.
13707 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13708 Javier Miranda <miranda@adacore.com>
13710 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
13711 predicate recursive, to handle complex expressions on literals whose
13712 spurious ambiguity comes from the abstract interpretation of some
13714 (Interface_Present_In_Ancestor): Add support to concurrent record
13716 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
13717 Is_Abstract_Subprogram and Is_Abstract_Type.
13719 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13720 Javier Miranda <miranda@adacore.com>
13722 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
13723 dereference of a local object R created as a reference to another
13724 object O, use the access level of O.
13725 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
13726 rather than local Same_Formal_Type, to check whether protected operation
13727 overrides an inherited one.
13728 (Same_Formal_Type): New predicate, used when matching signatures of
13729 overriding synchronized operations, to handle the case when a formal
13730 has a type that is a generic actual.
13731 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
13732 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
13733 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
13734 syntactic ambiguities involving indexing of function calls that return
13736 (Abstract_Interface_List): New subprogram that returns the list of
13737 abstract interfaces associated with a concurrent type or a
13738 concurrent record type.
13739 (Interface_Present_In_Parent): New subprogram used to check if a
13740 given type or some of its parents implement a given interface.
13741 (Collect_Abstract_Interfaces): Add support for concurrent types
13742 with interface types.
13743 (Has_Abstract_Interfaces): Add support for concurrent types with
13745 (Is_Parent): New subprogram that determines whether E1 is a parent
13746 of E2. For a concurrent type its parent is the first element of its
13747 list of interface types; for other types this function provides the
13748 same result than Is_Ancestor.
13749 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
13750 (Collect_Synchronized_Interfaces): Removed because the subprogram
13751 Collect_Abstract_Interfaces provides this functionality.
13752 (Collect_Abstract_Interfaces): Minor update to give support to
13753 concurrent types and thus avoid undesired code duplication.
13754 (Get_Subprogram_Entity): Handle entry calls.
13755 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
13757 (Enter_Name): Do not give -gnatwh hiding warning for record component
13758 entities, they never result in hiding.

13767 New field Exception_Label added
13768 (Local_Raise_Statements): New field in N_Exception_Handler_Node
13769 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

13773 can be an E_Return_Statement.
13774 (Is_Coextension): New flag for allocators.

13782 * s-tpobop.adb (Exceptional_Complete_Entry_Body): Undefer abortion
13783 before propagating exception.
13785 2007-04-06 Olivier Hainque <hainque@adacore.com>
13787 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
13788 an address always within the call instruction from a return address.

13793 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
13794 expression with a COMPOUND_EXPR including the call instead of emitting
13795 the call directly here.
13796 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
13797 high bound is constant and the slice is empty. Tidy.
13798 (tree_transform, case N_Op_Not): Handle properly the case where the
13799 operation applies to a private type whose full view is a modular type.
13800 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
13801 Address_Clause, use the associated Expression as the GNAT tree
13802 representing the choice value to ensure the corresponding GCC tree is
13803 of the proper kind.
13804 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
13805 instead of just the operands, as the base GCC stabilize_reference does.
13806 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
13807 requested; otherwise fail.
13808 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

13813 implementation of UI_Div.
13814 (UI_Div): Reimplement as a call to UI_Div_Rem.
13815 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
13816 remainder, avoiding the cost of a multiplication and a subtraction.
13817 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
13818 provides both quotient and remainder in a single computation.
13819 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
13820 functions for uint.
13821 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
13822 is undefined if the given n is not inversible.
13824 2007-04-06 Olivier Hainque <hainque@adacore.com>
13826 * utils2.c (known_alignment): Handle COMPOUND_EXPR, COND_EXPR and
13827 BIT_AND_EXPR. Handle also VIEW_CONVERT_EXPR, as the other conversion

13831 Olivier Hainque <hainque@adacore.com>
13833 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
13834 when updating the contents of the old pointer to an unconstrained array.
13835 (end_subprog_body): Set error_gnat_node to Empty.
13836 (write_record_type_debug_info): Do not be unduly sparing with our bytes.

13842 (gnat_install_builtins): Adjust comments.
13843 (builtin_function): Set DECL_BUILTIN_CLASS and DECL_FUNCTION_CODE before

13845 function declaration node.
13846 (builtin_decl_for): Search the builtin_decls list.
13848 2007-04-06 Eric Botcazou <botcazou@adacore.com>

13899 * decl.c (gnat_to_gnu_entity): Likewise.
13900 * trans.c (Attribute_to_gnu, gnat_to_gnu, emit_check): Likewise.

13903 * utils2.c (gnat_truthvalue_conversion, compare_arrays,
13904 nonbinary_modular_operation, build_binary_op, build_unary_op,

14068 (mainly static expression evaluation).
14069 Reword some continuation messages
14070 Add some \\ sequences to continuation messages
14071 (Resolve_Call): Refine infinite recursion case. The test has been

14085 during analysis, and use May_Be_Lvalue to distinguish read/write.
14086 (Valid_Array_Conversion): New procedure, abstracted from
14087 Valid_Conversion, to incorporate accessibility checks for arrays of
14088 anonymous access types.
14089 (Valid_Conversion): For a conversion to a numeric type occurring in an
14090 instance or inlined body, no need to check that the operand type is
14091 numeric, since this has been checked during analysis of the template.

14804 (Is_Self_Referential_Init): Remove, not needed.
14805 (Is_Self_Referential_Init): New predicate to simplify handling of self
14806 referential components in record aggregates.
14807 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
14808 check for presence of entity before checking for self-reference.
14809 (Has_Default_Init_Comps): Return True if a component association is a
14810 self-reference to the enclosing type, which can only come from a
14811 default initialization.
14812 (Make_OK_Assignment_Statement): If the expression is of the form
14813 Typ'Acc, where Acc is an access attribute, the expression comes from a
14814 default initialized self-referential component.
14815 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
14816 that has been derived from several abstract interfaces we must also
14817 initialize the tags of the secondary dispatch tables.

14821 Javier Miranda <miranda@adacore.com>
14822 Robert Dewar <dewar@adacore.com>
14825 (Expand_Access_To_Protected_Op): If the context indicates that an access
14826 to a local operation may be transfered outside of the object, create an
14827 access to the wrapper operation that must be used in an external call.
14828 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
14829 target, pass the Valid attribute applied to a floating-point prefix on
14830 to the back end without expansion.
14831 (Storage_Size): Use the new run-time function Storage_Size to retrieve
14832 the allocated storage when it is specified by a per-object expression.
14833 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
14834 Nothing to do here, the attribute has been rewritten during semantic
14836 (Expand_Attribute_Reference): Handle expansion of the new Priority
14838 (Find_Fat_Info): Handle case of universal real
14839 (Expand_Access_To_Protected_Op): Fix use of access to protected
14840 subprogram from inside the body of a protected entry.
14841 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
14842 'Access and 'Unrestricted_Access, to transform the attribute reference
14843 into a fat pointer.
14844 (Is_Constrained_Aliased_View): New predicate to help determine whether a
14845 subcomponent's enclosing variable is aliased with a constrained subtype.
14846 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
14847 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
14848 an aliased prefix must be known to be constrained in order to use True
14849 for the attribute value, and now it's possible for some aliased views
14850 to be unconstrained.
14852 2006-10-31 Robert Dewar <dewar@adacore.com>
14854 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
14855 (Expand_Entity_Reference): Correct error of not handling subprogram
14856 formals in current_value processing.
14858 2006-10-31 Javier Miranda <miranda@adacore.com>
14859 Robert Dewar <dewar@adacore.com>
14860 Ed Schonberg <schonberg@adacore.com>
14861 Gary Dismukes <dismukes@adacore.com>
14863 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
14864 register in the final list objects containing class-wide interfaces;
14865 otherwise we incorrectly register the tag of the interface in the final
14867 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
14868 generate the wrapper if the parent primitive is abstract. This is
14869 required to report the correct error message.
14870 (Expand_N_Subtype_Indication): Do validity checks on range
14871 (Clean_Task_Names): If an initialization procedure includes a call to
14872 initialize a task (sub)component, indicate that the procedure will use
14873 the secondary stack.
14874 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
14875 compatibility for interfacing with CPP by default.
14876 (Expand_N_Object_Declaration): Only build an Adjust call when the
14877 object's type is a nonlimited controlled type.
14878 * exp_ch3.adb: Add with and use of Exp_Ch6.
14879 (Expand_N_Object_Declaration): Check for object initialization that is a
14880 call to build-in-place function and apply Make_Build_In_Place_Call_In_
14881 Object_Declaration to the call.
14882 (Freeze_Type): When the designated type of an RACW was not frozen at the
14883 point where the RACW was declared, validate the primitive operations
14884 with respect to E.2.2(14) when it finally is frozen.
14885 (Build_Initialization_Call,Expand_Record_Controller): Rename
14886 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
14887 return-by-reference has no meaning in Ada 2005.
14888 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
14889 to register tag of the immediate ancestor interfaces in the
14890 run-time structure.
14891 (Init_Secondary_Tags): Moved to the specification to allow the
14892 initialization of extension aggregates with abstract interfaces.
14893 (Build_Master_Renaming): Make public, for use by function declarations
14894 whose return type is an anonymous access type.
14895 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
14896 Insert_List_Before_And_Analyze after the generation of the specs
14897 associated with null procedures.
14898 (Expand_Tagged_Root): Update documentation in its specification.
14899 (Init_Secondary_Tags): Update documentation.
14900 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
14901 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
14902 then generate code to inherit the contents of the dispatch table
14903 directly from the ancestor.
14904 (Expand_Record_Controller): Insert controller component after tags of
14905 implemented interfaces.
14906 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
14907 create null procedure overridings when null procedures are inherited
14909 (Make_Null_Procedure_Specs): New procedure to generate null procedure
14910 declarations for overriding null primitives inherited from interfaces.
14911 (Is_Null_Interface_Procedure): New function in
14912 Make_Null_Procedure_Specs.
14913 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
14914 immediate ancestor of a tagged type is an abstract interface type we
14915 must generate the specification of the predefined primitives associated
14916 with controlled types (because the dispatch table of the ancestor is
14917 null and hence these entries cannot be inherited). This is required to
14918 elaborate well the dispatch table.

14926 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
14928 (Expand_N_In): Do validity checks on range
14929 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
14930 (Expand_N_Allocator): For "new T", if the object is constrained by
14931 discriminant defaults, allocate the right amount of memory, rather than
14932 the maximum for type T.
14933 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
14934 when the allocator is initialized by a build-in-place call, since the
14935 allocator is already rewritten as a reference to the function result,
14936 and this prevents an unwanted duplication of the function call.
14937 Add with and use of Exp_Ch6.
14938 (Expand_Allocator_Expresssion): Check for an allocator whose expression
14939 is a call to build-in-place function and apply
14940 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
14941 untagged designated types).
14942 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
14943 optimization if source or target is biased.
14944 (Expand_N_Allocator): Add comments for case of an allocator within a
14945 function that returns an anonymous access type designating tasks.
14946 (Expand_N_Allocator): apply discriminant checks for access
14947 discriminants of anonymous access types (AI-402, AI-416)

14954 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
14956 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
14957 (Expand_N_Assignment_Statement): Call
14958 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
14959 build-in-place function call. Currently, this can happen only for
14960 assignments that come from aggregates.
14961 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
14962 in order to alleviate the upward compatibility introduced by AI-318.
14963 (Expand_N_Extended_Return_Statement): Add support for handling the
14964 return object as a build-in-place result.
14965 (Expand_Non_Function_Return): Implement simple return statements nested
14966 within an extended return.
14967 (Enable_New_Return_Processing): Turn on the new processing of return
14969 (Expand_Non_Function_Return): For a return within an extended return,
14970 don't raise Program_Error, because Sem_Ch6 now gives a warning.
14971 (Expand_N_Extended_Return_Statement): Implement AI-318
14972 (Expand_Simple_Function_Return): Ditto.
14973 (Expand_N_If_Statement): Handle new -gnatwt warning
14974 (Expand_N_Case_Statement): Handle new -gnatwt warning
14975 (Expand_N_Assignment): Handle assignment to the Priority attribute of
14976 a protected object.
14977 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
14978 validity checking of assignments to elementary record components.
14979 (Expand_N_Return_Statement): return Class Wide types on the secondary
14980 stack independantly of their controlled status since with HIE runtimes,
14981 class wide types are not potentially controlled anymore.
14983 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
14986 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
14987 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
14988 it expects a block, procedure, or task. The return statement will get
14989 turned into a block, and Expand_Cleanup_Actions will happen then.

14992 Ed Schonberg <schonberg@adacore.com>
14993 Bob Duff <duff@adacore.com>
14994 Gary Dismukes <dismukes@adacore.com>
14996 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
14998 (Expand_Inlined_Call): Tagged types are by-reference types, and
14999 therefore should be replaced by a renaming declaration in the expanded
15000 body, as is done for limited types.
15001 (Expand_Call): If this is a call to a function with dispatching access
15002 result, propagate tag from context.
15003 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
15005 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
15006 build-in-place when the right-hand side of an assignment is a
15007 build-in-place function call.
15008 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
15009 of the explicit dereference of the allocator to the result subtype of
15010 the build-in-place function. This is needed to satisfy type checking
15011 in cases where the caller's return object is created by an allocator for
15012 a class-wide access type and the type named in the allocator is a
15014 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
15015 conversion of the reference to the declared object to the result subtype
15016 of the build-in-place function. This is needed to satisfy type checking
15017 in cases where the declared object has a class-wide type. Also, in the
15018 class-wide case, change the type of the object entity to the specific
15019 result subtype of the function, to avoid passing a class-wide object
15020 without explicit initialization to the back end.
15021 (Register_Interface_DT_Entry): Moved outside the body of
15022 Freeze_Subprogram because this routine is now public; it is called from
15023 Check_Dispatching_Overriding to handle late overriding of abstract
15024 interface primitives.
15025 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
15026 adding an implicit access actual on a call to a build-in-place function.
15027 (Expand_Actuals): Test for an actual parameter that is a call to a
15028 build-in-place function and apply
15029 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
15030 (Is_Build_In_Place_Function): New function to determine whether an
15031 entity is a function whose calls should be handled as build-in-place.
15032 (Is_Build_In_Place_Function_Call): New function to determine whether an
15033 expression is a function call that should handled as build-in-place.
15034 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
15035 calls to build-in-place functions as the initialization of an allocator.
15036 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
15037 handling calls to build-in-place functions in contexts that do not
15038 involve init of a separate object (for example, actuals of subprogram
15040 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
15041 handling calls to build-in-place functions as the initialization of an
15042 object declaration.
15043 (Detect_Infinite_Recursion): Add explicit parameter Process to
15044 instantiation of Traverse_Body to avoid unreferenced warning.
15045 (Check_Overriding_Inherited_Interfaces): Removed.
15046 (Register_Interface_DT_Entry): Code cleanup.
15047 (Register_Predefined_DT_Entry): Code cleanup.
15048 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
15049 inlined statements if within a transient scope.
15050 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
15051 formal parameters with occurrences of actuals in inlined body, establish
15052 visibility on the proper view of the actual's subtype for the body's
15054 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
15055 compatibility mode and we have an imported CPP subprogram because
15056 for now we assume that imported CPP primitives correspond with
15057 objects whose constructor is in the CPP side (and therefore we
15058 don't need to generate code to register them in the dispatch table).
15059 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
15060 aligned selected component.
15061 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
15062 the actual of an in-mode parameter is a type conversion.
15063 (Expand_Actuals): If the call does not come from source and the actual
15064 is potentially misaligned, let gigi handle it rather than rejecting the
15065 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
15066 Class Wide types as returning by reference independantly of their
15067 controlled status since with HIE runtimes class wide types are not
15068 potentially controlled anymore.
15070 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15072 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
15073 references that are private components of the protected object.
15074 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
15075 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
15076 instantiation to deal with warnings.
15077 (Initialize_Protection): If expression for priority is non-static, use
15078 System_Priority as its expected type, in case the expression has not
15081 2006-10-31 Robert Dewar <dewar@adacore.com>
15083 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
15084 initialization of Homonym_Len.
15085 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
15086 names from fully qualified name. Fixes problem of duplicate
15087 external names differing only in the presence of such a block name.
15089 2006-10-31 Thomas Quinot <quinot@adacore.com>
15090 Pablo Oliveira <oliveira@adacore.com>
15092 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
15093 subprogram Ids, even if they are not yet assigned.
15094 (Build_Subprogram_Id): It is now this function that will take care of
15095 calling Assign_Subprogram_Ids if necessary.
15096 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
15097 should be done only once they are assigned.
15098 (Build_From_Any_Function, case of tagged types): Add missing call to
15100 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
15101 type for an RACW type.
15102 (Add_RACW_Features): When processing an RACW declaration for which the
15103 designated type is already frozen, enforce E.2.2(14) rules immediately.
15104 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
15105 special reordering of controlling formals.
15107 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
15108 associated stub type for an RACW type.
15110 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15112 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
15113 fixed-point operations in an integer context, i.e. as operands of a
15114 conversion to an integer type, indicate that result must be rounded.
15116 2006-10-31 Robert Dewar <dewar@adacore.com>
15118 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
15119 cases, pass the encoding method, since it is now required by the run
15122 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
15123 assumption that Str'First = 1.
15124 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
15125 it on to the Value_Wide_Wide_Character call.
15126 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
15127 properly handles a string of the form quote-encoded_wide_char-quote.
15129 * s-wchcnv.adb: Minor reformatting
15131 2006-10-31 Javier Miranda <miranda@adacore.com>
15133 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
15134 run-time membership test to ensure that the constructed object
15135 implements the target abstract interface.
15137 2006-10-31 Robert Dewar <dewar@adacore.com>
15139 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
15140 Machine_Attribute pragma internally to implement the user pragma.
15141 Add processing for pragma Interface so that it is now completely
15142 equivalent to pragma Import.
15144 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
15145 so that it can be applied to all entities, including record components
15146 and enumeration literals.
15147 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
15148 priority ranges are correct, verify compatibility against task
15149 dispatching and locking policies, and if everything is correct an entry
15150 is added to the table containing priority specific dispatching entries
15151 for this compilation unit.
15152 (Delay_Config_Pragma_Analyze): Delay processing
15153 Priority_Specific_Dispatching pragmas because when processing the
15154 pragma we need to access run-time data, such as the range of
15155 System.Any_Priority.
15156 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
15157 Allow pragma Unreferenced as a context item
15158 Add pragma Preelaborable_Initialization

15160 now syntactically and semantically equivalent to Import.
15161 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
15162 insertion characters.
15163 Add handling for Pragma_Wide_Character_Encoding
15164 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
15165 never supercedes a real restriction, and that a real restriction
15166 always supercedes a warning.
15167 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

15174 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
15175 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
15176 Is_Inherently_Limited_Type, because return-by-reference has no meaning
15178 (Find_Node_To_Be_Wrapped): Use new method of determining the result
15179 type of the function containing a return statement, because the
15180 Return_Type field was removed. We now use the Return_Applies_To field.
15182 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
15183 (Build_Task_Image_Decl): If procedure is not called from an
15184 initialization procedure, indicate that function that builds task name
15185 uses the sec. stack. Otherwise the enclosing initialization procedure
15186 will carry the indication.
15187 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
15188 N_Object_Declaration instead.
15189 (Kill_Dead_Code): New interface to implement -gnatwt warning for
15190 conditional dead code killed, and change implementation accordingly.
15191 (Insert_Actions): Add N_Return_Object_Declaration case.
15192 Correct comment to mention N_Extension_Aggregate node.
15193 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
15194 attempts to save information for global variables which cannot be
15196 (Get_Current_Value_Condition): Handle conditions the other way round
15197 (constant on left). Also handle right operand of AND and AND THEN

15199 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
15200 (Get_Current_Value_Condition): Handle simple boolean operands
15201 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
15202 (Get_Current_Value_Condition): If the variable reference is within an
15203 if-statement, does not appear in the list of then_statments, and does
15204 not come from source, treat it as being at unknown location.
15205 (Get_Current_Value_Condition): Enhance to allow while statements to be
15206 processed as well as if statements.
15207 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
15209 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
15210 of loop. This is safe now that we fixed Kill_Current_Values.
15211 (OK_To_Do_Constant_Replacement): Check whether current scope is
15212 Standard, before examining outer scopes.
15214 2006-10-31 Vincent Celier <celier@adacore.com>
15216 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
15217 When True, apply VMS treatment to children of packages A, G, I and S.

15235 (Generate_Reference): Accept an implicit reference generated for a
15236 default in an instance.
15237 (Generate_Reference): Accept a reference for a node that is not in the
15238 main unit, if it is the generic body corresponding to an subprogram
15241 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
15243 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
15245 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
15247 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
15248 use clauses, to avoid messages on packages used to qualify, and also
15249 to avoid messages from obsolescent units.
15250 (Warn_On_Useless_Assignments): Don't generate messages for imported
15251 and exported variables.
15252 (Warn_On_Useless_Assignments): New procedure
15253 (Output_Obsolescent_Entity_Warnings): New procedure
15254 (Check_Code_Statement): New procedure
15256 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag

15258 (Last_Assignment): New field for useless assignment warning
15260 2006-10-31 Olivier Hainque <hainque@adacore.com>
15262 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
15263 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
15265 2006-10-31 Bob Duff <duff@adacore.com>
15266 Robert Dewar <dewar@adacore.com>
15267 Ed Schonberg <schonberg@adacore.com>
15269 * g-awk.adb (Default_Session, Current_Session): Compile this file in
15270 Ada 95 mode, because it violates the new rules for AI-318.
15272 * g-awk.ads: Use overloaded subprograms in every case where we used to
15273 have a default of Current_Session. This makes the code closer to be
15274 correct for both Ada 95 and 2005.
15276 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
15277 code, relying on the fact that the compiler generates a warning
15278 instead of an error in -gnatg mode.
15280 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
15281 E_Return_Statement entity kind.
15282 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
15284 * par.adb (P_Interface_Type_Definition): Addition of one formal to
15285 report an error if the reserved word abstract has been previously found.
15286 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
15288 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
15289 parenthesized range attribute usage
15290 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
15292 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
15293 in the syntax for extended_return_statement. This is not in the latest
15294 RM, but the ARG is expected to issue an AI allowing this.
15295 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
15296 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
15297 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
15298 P_Return_Statement): Parse the new syntax for extended_return_statement.
15300 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
15301 Output_End_Missing): Add error-recovery code for the new
15302 extended_return_statement syntax; that is, the new E_Return entry on
15305 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
15306 limited to nonlimited, because otherwise we violate the new Ada 2005
15307 rules about returning limited types in function Create_AST_Handler in
15310 * sem.adb (Analyze): Add cases for new node kinds
15311 N_Extended_Return_Statement and N_Return_Object_Declaration.
15313 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
15314 type is in the same category as type of context before applying check,
15315 to prevent anomalies in instantiations.
15316 (Resolve_Aggregate): Remove test for limited components in aggregates.
15317 It's unnecessary in Ada 95, because if it has limited components, then
15318 it must be limited. It's wrong in Ada 2005, because limited aggregates
15320 (Resolve_Record_Aggregate): Move check for limited types later, because
15321 OK_For_Limited_Init requires its argument to have been resolved.
15322 (Get_Value): When copying the component default expression for a
15323 defaulted association in an aggregate, use the sloc of the aggregate
15324 and not that of the original expression, to prevent spurious
15325 elaboration errors, when the expression includes function calls.
15326 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
15327 were missing. We also didn't handle qualified expressions. Now also
15328 allow function calls. Use new common routine OK_For_Limited_Init.
15329 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
15330 with space can upper case letter).
15332 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
15333 Has_Static_Discriminants flag
15334 (Record_Type_Declaration): Diagnose an attempt to declare an interface
15335 type with discriminants.
15336 (Process_Range_Expr_In_Decl): Do validity checks on range
15337 (Build_Discriminant_Constraints): Use updated form of
15338 Denotes_Discriminant.
15339 (Process_Subtype): If the subtype is a private subtype whose full view
15340 is a concurrent subtype, introduce an itype reference to prevent scope
15342 (Build_Derived_Record_Type, Collect_Interface_Primitives,
15343 Record_Type_Declaration): The functionality of the subprograms
15344 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
15345 is now performed by a single routine.
15346 (Build_Derived_Record_Type): If the type definition includes an explicit
15347 indication of limitedness, then the type must be marked as limited here
15348 to ensure that any access discriminants will not be treated as having
15349 a local anonymous access type.
15350 (Check_Abstract_Overriding): Issue a detailed error message when an
15351 abstract subprogram was not overridden due to incorrect mode of its
15353 (Analyze_Private_Extension_Declaration): Add support for the analysis of
15354 synchronized private extension declarations. Verify that the ancestor is
15355 a limited or synchronized interface or in the generic case, the ancestor
15356 is a tagged limited type or synchronized interface and all progenitors
15357 are either limited or synchronized interfaces.
15358 Derived_Type_Declaration): Check for presence of private extension when
15359 dealing with synchronized formal derived types.
15360 Process_Full_View): Enchance the check done on the usage of "limited" by
15361 testing whether the private view is synchronized.
15362 Verify that a synchronized private view is completed by a protected or
15364 (OK_For_Limited_Init_In_05): New function.
15365 (Analyze_Object_Declaration): Move check for limited types later,
15366 because OK_For_Limited_Init requires its argument to have been resolved.
15367 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
15368 in order to alleviate the upward compatibility introduced by AI-318.
15369 (Constrain_Corresponding_Record): If the constraint is for a component
15370 subtype, mark the itype as frozen, to avoid out-of-scope references to
15371 discriminants in the back-end.
15372 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
15373 this subprogram against wrong sources.
15374 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
15375 discriminant of limited type completed with a protected type, when the
15376 discriminant is used to constrain a private component of the type, and
15377 expansion is disabled.
15378 (Find_Type_Of_Object): Do not treat a return subtype that is an
15379 anonymous subtype as a local_anonymous_type, because its accessibility
15380 level is the return type of the enclosing function.
15381 (Check_Initialization): In -gnatg mode, turn the error "cannot
15382 initialize entities of limited type" into a warning.
15383 (OK_For_Limited_Init): Return true for generated nodes, since it
15384 sometimes violates the legality rules.
15385 (Make_Incomplete_Declaration): If the type for which an incomplete
15386 declaration is created happens to be the currently visible entity,
15387 preserve the homonym chain when removing it from visibility.
15388 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
15389 inherited subprograms.
15390 (Access_Definition): If this is an access to function that is the return
15391 type of an access_to_function definition, context is a type declaration
15392 and the scope of the anonymous type is the current one.
15393 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
15394 incomplete subtype to the set of private dependents of the original
15396 (Constrain_Discriminated_Type): Emit an error message whenever an
15397 incomplete subtype is being constrained.
15398 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
15399 corresponding subtype of the full view of the original incomplete type.
15400 (Check_Incomplete): Properly detect invalid usage of incomplete types
15403 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
15405 * g-catiio.ads, g-catiio.adb (Value): New function.

15414 Robert Dewar <dewar@adacore.com>
15416 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
15417 handling executable extension manually and duplicating code.
15419 * make.adb: Implement new -S switch
15420 (Gnatmake): Use new function Osint.Executable_Name instead
15421 of handling executable extension manually.
15423 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
15424 is specified, the executable name ends with this suffix.
15425 Take advantage of Osint.Executable_Name instead of duplicating code.
15427 * switch-m.adb: Recognize new gnatmake -S switch
15429 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
15431 (Get_Target_Parameters): Set Executable_Extension_On_Target if
15434 * makeusg.adb: Add line for gnatmake -S switch
15436 2006-10-31 Vincent Celier <celier@adacore.com>
15438 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
15439 call it with -static-libgcc, as there are some platforms, such as
15440 Darwin, where one of these two switches is compulsory to link.
15442 2006-10-31 Vincent Celier <celier@adacore.com>
15444 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
15445 instead of ADA_PROJECT_PATH, for the project path.
15446 (Gnatls): When displaying the project path directories, use host dir
15449 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
15450 names in the project path, as absolute paths may correspond to
15451 multi-valued VMS logical names.
15453 2006-10-31 Vincent Celier <celier@adacore.com>
15455 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
15456 absolute path name.
15457 (Locate_Regular_File): Ditto
15458 (Change_Dir): Remove, no longer used
15459 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
15460 on Windows. Get it calling Get_Current_Dir.
15461 (OpenVMS): Remove imported boolean, no longer needed.
15462 (Normalize_Pathname)[VMS]: Do not resolve directory names.
15463 (Pid_To_Integer): New function to convert a Process_Id to Integer
15465 2006-10-31 Thomas Quinot <quinot@adacore.com>

15468 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
15470 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
15473 2006-10-31 Robert Dewar <dewar@adacore.com>

15480 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
15482 2006-10-31 Robert Dewar <dewar@adacore.com>
15484 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
15486 (Layout_Variant_Record): Retrieve the discriminants from the entity
15487 rather than from the type definition, because in the case of a full
15488 type for a private type we need to take the discriminants from the
15490 (Layout_Component_List): When applying the Max operator to variants with
15491 a nonstatic size, check whether either operand is static and scale that
15492 operand from bits to storage units before applying Max.
15493 (Layout_Type): In VMS, if a C-convention access type has no explicit
15494 size clause (and does not inherit one in the case of a derived type),
15495 then the size is reset to 32 from 64.
15497 2006-10-31 Vincent Celier <celier@adacore.com>
15499 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
15500 its file has already been loaded, according to the unit being loaded,
15501 not to the current value of Multiple_Unit_Index.
15503 2006-10-31 Thomas Quinot <quinot@adacore.com>
15504 Eric Botcazou <ebotcazou@adacore.com>

15539 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15541 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
15542 Process_Body_Clauses): If the context of a body includes a use clause
15543 for P.Q then a with_clause for P in the same body is not redundant,
15544 even if the spec also has a with_clause on P.
15545 Add missing continuation mark to error msg
15546 (Build_Limited_Views): A limited view of a type is tagged if its
15547 declaration includes a record extension.
15548 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
15549 node, even if the subunit has errors. This avoids malfunction by
15550 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
15551 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
15552 generation of obsolescent messages for with statements (cannot do
15553 this too early, or we cannot implement avoiding the messages in the
15554 case of obsolescent units withing obsolescent units).
15555 (Install_Siblings): If the with_clause is on a remote descendant of
15556 an ancestor of the current compilation unit, find whether there is
15557 a sibling child unit that is immediately visible.
15558 (Remove_Private_With_Clauses): New procedure, invoked after completing
15559 the analysis of the private part of a nested package, to remove from
15560 visibility the private with_clauses of the enclosing package
15562 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
15563 now centralized in Generate_Reference.
15564 (Install_Limited_Context_Clauses): Remove superfluous error
15565 message associated with unlimited view visible through use
15566 and renamings. In addition, at the point in which the error
15567 is reported, we add the backslash to the text of the error
15568 to ensure that it is reported as a single error message.
15569 Use new // insertion for some continuation messages
15570 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
15571 to create implicit with_clause for parent unit mentioned in original
15572 limited_with_clause.
15573 (Install_Limited_With_Unit): Set entity of parent identifiers if the
15574 unit is a child unit. For ASIS queries.
15575 (Analyze_Subunit): If the subunit appears within a child unit, make all
15576 ancestor child units directly visible again.

15591 a formal object declaration with an access definition or a subtype mark
15592 with a null exclusion.
15593 (P_Generic_Association): Handle association with box, and others_choice
15594 with box, to support Ada 2005 partially parametrized formal packages.
15596 2006-10-31 Robert Dewar <dewar@adacore.com>
15597 Javier Miranda <miranda@adacore.com>

15600 (P_Type_Declaration): Remove barrier against the reserved word "limited"
15601 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
15602 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
15603 private extensions.
15604 (P_Type_Declaration): Add the new actual Abstract_Present to every call
15605 to P_Interface_Type_Definition.
15606 (P_Interface_Type_Definition): Addition of one formal to report an error
15607 if the reserved word abstract has been previously found.
15608 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
15609 object renaming declaration with an access definition or subtype mark
15610 with a possible null exclusion.

15632 2006-10-31 Vincent Celier <celier@adacore.com>
15634 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
15635 on VMS, change "__" to '.' before checking the name.
15636 (Record_Ada_Source): Always add the source file name in the list of
15637 of sources, even if it is not the first time, as it is for another
15639 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
15640 dot, instead of replacing only the first '_'.
15642 * prj-part.adb (Parse): Convert project file path to canonical form
15644 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
15645 extended, the project id of the project extending it is recorded in its
15646 data, even when it has already been processed as an imported project.
15648 2006-10-31 Robert Dewar <dewar@adacore.com>

15654 Robert Dewar <dewar@adacore.com>
15656 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
15657 only a restriction warning is active for the given restriction. This is
15658 desirable because we do not want to modify code in the case where only
15660 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
15661 causes overriding of real restrictions.
15662 Take advantage of new No_Restrictions constant.
15664 * raise.h: (__gnat_set_globals): Change profile.
15666 2006-10-31 Arnaud Charlet <charlet@adacore.com>
15668 * rtsfind.adb: Remove s-polint from comment as it exists no more.

15693 (OK_Self_Reference): New subprogram to check the legality of an access
15694 attribute whose prefix is the type of an enclosing aggregate.
15695 Generalizes previous mechanism to handle attribute references nested
15696 arbitrarily deep within the aggregate.
15697 (Analyze_Access_Attribute): An access attribute whose prefix is a type
15698 can appear in an aggregate if this is a default-initialized aggregate
15699 for a self-referential type.
15700 (Resolve_Attribute, case Access): Ditto.
15701 Add support for new implementation defined attribute Stub_Type.
15702 (Eval_Attribute, case Attribute_Stub_Type): New case.
15703 (Analyze_Attribute, case Attribute_Stub_Type): New case.
15704 (Stream_Attribute_Available): Implement using new subprogram from
15705 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
15706 Has_Specified_Stream_Attribute flag.
15707 Disallow Storage_Size and Storage_Pool for access to subprogram
15708 (Resolve_Attribute, case 'Access et al): Take into account anonymous
15709 access types of return subtypes in extended return statements. Remove
15710 accessibility checks on anonymous access types when Unchecked_Access is
15712 (Analyze_Attribute): Add support for the use of 'Class to convert
15713 a class-wide interface to a tagged type.
15714 Add support for the attribute Priority.
15715 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
15716 whether the designated type is discriminated with a constrained partial
15717 view and require static matching in that case.
15718 Add local variable Des_Btyp. The Designated_Type
15719 of an access to incomplete subtype is either its non-limited view if
15720 coming from a limited with or its etype if regular incomplete subtype.
15722 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
15723 Fix predicate to identify and allow cases of (expander-generated)
15724 references to tag of designated object of a RACW.
15725 (Validate_Static_Object_Name): In Ada 2005, a formal object is
15726 non-static, and therefore cannot appear as a primary in a preelaborable
15728 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
15729 Has_Read_Write_Attributes.
15730 (Has_Read_Write_Attributes): Reimplement in termes of
15731 Has_Stream_Attribute_Definition.
15732 (Missing_Read_Write_Attributes): When checking component types in a
15733 record, unconditionally call Missing_Read_Write_Attributes recursively
15734 (remove guard checking for Is_Record_Type / Is_Access_Type).
15736 2006-10-31 Robert Dewar <dewar@adacore.com>
15738 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
15739 useless assignments here and conditionalize it on absence of exception
15741 (Analyze_Exception_Handlers): Small code reorganization of error
15742 detection code, for new handling of formal packages.
15744 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15745 Hristian Kirtchev <kirtchev@adacore.com>
15747 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
15748 that has been constant-folded, preserve information of original tree,
15750 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
15751 generated private extension declaration if the formal derived type is
15752 synchronized. Carry synchronized present over to the generated private
15754 (Validate_Derived_Type_Instance): Ensure that the actual of a
15755 synchronized formal derived type is a synchronized tagged type.
15756 (Instantiate_Formal_Package): When creating the instantiation used to
15757 validate the actual package of a formal declared without a box, check
15758 whether the formal itself depends on a prior actual.
15759 (Instantiate_Formal_Subprogram): Create new entities for the defining
15760 identifiers of the formals in the renaming declaration, for ASIS use.
15761 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
15762 a renaming declaration or a subtype declaration for an actual in an
15763 instance, capture location information of declaration in generic, for
15765 (Instantiate_Formal_Package): Add comments on needed additional tests.
15766 AI-317 (partial parametrization) is fully implemented.
15767 (Validate_Private_Type_Instance): Add check for actual which
15768 must have preelaborable initialization
15769 Use new // insertion for some continuation messages
15770 (Analyze_Formal_Object_Declaration): Change usage of Expression to
15771 Default_Expression. Add type retrieval when the declaration has an
15772 access definition. Update premature usage of incomplete type check.
15773 (Check_Access_Definition): New subsidiary routine. Check whether the
15774 current compilation version is Ada 05 and the supplied node has an
15776 (Instantiate object): Alphabetize local variables. Handle the creation
15777 of new renaming declarations with respect to the kind of definition
15778 used - either an access definition or a subtype mark. Guard against
15779 unnecessary error message in the context of anonymous access types after
15780 they have been resolved. Add check for required null exclusion in a
15781 formal object declaration.
15782 (Switch_View): A private subtype of a non-private type needs to be
15783 switched (the base type can have been switched without its private
15784 dependents because of the last branch of Check_Private_View.
15785 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
15787 (Instantiate_Type): Emit an error message whenever a class-wide type of
15788 a tagged incomplete type is used as a generic actual.
15789 (Find_Actual_Type): Extend routine to handle a component type in a child
15790 unit that is imported from a formal package in a parent.
15791 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
15792 agree on constrainedness, rather than checking against ultimate ancestor
15793 (Instantiate_Subprogram_Body): Create a cross-reference link to the
15794 generic body, for navigation purposes.
15796 2006-10-31 Robert Dewar <dewar@adacore.com>
15797 Thomas Quinot <quinot@adacore.com>
15799 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
15801 (New_Stream_Subprogram): When processing an attribute definition clause
15802 for a stream-oriented subprogram, record an entity node occurring at
15803 the point of clause to use for checking the visibility of the clause,
15804 as defined by 8.3(23) as amended by AI-195.
15805 (New_Stream_Subprogram): New procedure, factoring behaviour from both
15806 New_Stream_Function and New_Stream_Procedure.
15807 (New_Stream_Function, New_Stream_Procedure): Removed.
15808 (Analyze_Attribute_Definition_Clause, case Address): Check new
15809 Alignment_Check check

15812 Javier Miranda <miranda@adacore.com>
15813 Robert Dewar <dewar@adacore.com>
15815 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
15816 generate the same errors compiling under -gnatc.
15817 (Try_Object_Operation): If no candidate interpretation succeeds, but
15818 there is at least one primitive operation with the right name, report
15819 error in call rather than on a malformed selected component.
15820 (Analyze_Selected_Component): If the prefix is an incomplete type from
15821 a limited view, and the full view is available, use the full view to
15822 determine whether this is a prefixed call to a primitive operation.
15823 (Operator_Check): Verify that a candidate interpretation is a binary
15824 operation before checking the type of its second formal.
15825 (Analyze_Call): Add additional warnings for function call contexts not
15827 (Analyze_Allocator): Move the check for "initialization not allowed for
15828 limited types" after analyzing the expression. This is necessary,
15829 because OK_For_Limited_Init looks at the structure of the expression.
15830 Before analysis, we don't necessarily know what sort of expression it
15831 is. For example, we don't know whether F(X) is a function call or an
15832 indexed component; the former is legal in Ada 2005; the latter is not.
15833 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
15834 were missing. We also didn't handle qualified expressions. Now also
15835 allow function calls. Use new common routine OK_For_Limited_Init.
15836 (Analyze_Type_Conversion): Do not perform some legality checks in an
15837 instance, because the error message will be redundant or spurious.
15838 (Analyze_Overloaded_Selected_Component): Do not do style check when
15839 setting an entity, since we do not know it is the right entity yet.
15840 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
15841 (Analyze_Overloaded_Selected_Component): Same change
15842 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
15843 since regular incomplete subtypes are transformed into corresponding
15844 subtypes of their full views.
15845 (Complete_Object_Operation): Treat name of transformed subprogram call
15846 as coming from source, for browsing purposes.
15847 (Try_Primitive_Operation): If formal is an access parameter, compare
15848 with base type of object to determine whether it is a primitive
15850 (Operator_Check): If no interpretation of the operator matches, check
15851 whether a use clause on any candidate might make the operation legal.
15852 (Try_Class_Wide_Operation): Check whether the first parameter is an
15853 access type whose designated type is class-wide.

15860 warn on infinite loops.
15861 Add \\ to some continuation messages
15862 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
15863 (Process_Bounds): If the bounds are integer literals that result from
15864 constant-folding, and they carry a user-defined type, preserve that type
15865 rather than treating this as an integer range.
15866 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
15867 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
15868 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
15869 left hand side of assignment.
15870 (Analyze_Assignment): Add suport to manage assigments to the attribute
15871 priority of a protected object.
15872 (Check_Possible_Current_Value_Condition): Allow fully qualified names
15873 not just identifiers.
15874 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
15875 or AND THEN for possible tracking.
15876 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
15877 case of while loops so we can track values in the loop body.
15879 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15880 Hristian Kirtchev <kirtchev@adacore.com>
15881 Bob Duff <duff@adacore.com>
15883 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
15884 procedure cannot be a protected operation (it is a basic_declaration,
15885 not a subprogram_declaration).
15886 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
15887 Subp. Add logic for entry processing.
15888 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
15889 Determine whether an entry or subprogram of a protected or task type
15890 override an inherited primitive of an implemented interface.
15891 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
15892 Update the actual used in calls to Check_Overriding_Indicator.
15893 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
15894 generate the proper reference to the parent unit, for cross-reference.
15895 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
15897 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
15898 (Add_Extra_Formal): Revise procedure to allow passing in associated
15899 entity, scope, and name suffix, and handle setting of the new
15900 Extra_Formals field.
15901 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
15902 pass new parameters. Add support for adding the new extra access formal
15903 for functions whose calls are treated as build-in-place.
15904 (Analyze_A_Return_Statement): Correct casing in error message.
15905 Move Pop_Scope to after Analyze_Function_Return, because an extended
15906 return statement really is a full-fledged scope. Otherwise, visibility
15907 doesn't work right. Correct use of "\" for continuation messages.
15908 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
15909 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
15910 the node doesn't get properly marked as analyzed.
15911 (Analyze_Subprogram_Body): If subprogram is a function that returns
15912 an anonymous access type that denotes a task, build a Master Entity
15914 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
15915 proper usage of null exclusion in a result definition.
15916 (Process_Formals): Code cleanup and new error message.
15917 (Process_Formals): Detect incorrect application of null exclusion to
15919 (Conforming_Types): Handle conformance between [sub]types and itypes
15920 generated for entities that have null exclusions applied to them.
15921 (Maybe_Primitive_Operation): Add an additional type retrieval when the
15922 base type is an access subtype. This case arrises with null exclusions.
15923 (New_Overloaded_Entity): Do not remove the overriden entity from the
15924 homonym chain if it corresponds with an abstract interface primitive.
15925 (Process_Formals): Replace membership test agains Incomplete_Kind with a
15926 call to the synthesized predicate Is_Incomplete_Type.
15927 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
15929 (Analyze_Subprogram_Declaration): Check that abstract interface
15930 primitives are abstract or null.
15931 (Analyze_Subprogram_Specification): Remove previous check for abstract
15932 interfaces because it was not complete.
15933 (Has_Interface_Formals): Removed.

15936 Javier Miranda <miranda@adacore.com>
15938 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
15939 of Analyze_Package_Body, to create Itype references for anonymous
15940 access types created in the package declaration, whose designated types
15941 may have only a limited view.
15942 (Analyze_Package_Specification): For the private part of a nested
15943 package, install private_with_clauses of enclosing compilation unit if
15944 we are in its visible part.
15945 (Declare_Inherited_Private_Subprograms): Complete barrier
15946 to ensure that the primitive operation has an alias to some parent
15947 primitive. This is now required because, after the changes done for the
15948 implementation of abstract interfaces, the contents of the list of
15949 primitives has entities whose alias attribute references entities of
15950 such list of primitives.
15951 (Analyze_Package_Specification): Simplify code that handles parent units
15952 of instances and formal packages.
15953 (Uninstall_Declarations): Check the convention consistency among
15954 primitive overriding operations of a tagged record type.

15958 Javier Miranda <miranda@adacore.com>
15959 Ed Schonberg <schonberg@adacore.com>
15961 * sem_ch8.adb: Minor error msg rewording
15962 (Undefined): When checking for misspellings, invert arguments (to get
15963 expected and found set right)
15964 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
15965 (Analyze_Generic_Renaming): Same fix
15966 (Use_One_Package): Do not take into account the internal entities of
15967 abstract interfaces during the analysis of entities that are marked
15968 as potentially use-visible.
15969 (Find_Type): Handle the case of an attribute reference for
15970 implementation defined attribute Stub_Type (simply let the analysis of
15971 the attribute reference rewrite it).
15972 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
15973 type that appears in a Use_Type clause.
15974 (Analyze_Object_Renaming): Add support for renaming of the Priority
15976 (Find_Type): In Ada 2005, a task type can be used within its own body,
15977 when it appears in an access definition.
15978 (Analyze_Object_Renaming): Remove warning on null_exclusion.
15979 (Analyze_Object_Renaming): Introduce checks for required null exclusion
15980 in a formal object declaration or in a subtype declaration.
15981 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
15982 (Check_Null_Exclusion): New local routine to
15983 Analyze_Subprogram_Renaming. Check whether the formals and return
15984 profile of a renamed subprogram have required null exclusions when
15985 their counterparts of the renaming already impose them.
15986 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
15987 Determine whether an entity is inside a generic scope.
15988 (In_Open_Scope): First pass of documentation update.
15989 (Find_Expanded_Name): Add support for shadow entities associated with
15990 limited withed packages. This is required to handle nested packages.
15991 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
15992 that makes a renaming of a limited withed package illegal.

15997 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
15998 Check_Overriding_Indicator.
15999 (Analyze_Task_Definition): Ditto.
16000 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
16001 (Check_Overriding_Indicator): To find overridden interface operation,
16002 examine only homonyms that have an explicit subprogram declaration, not
16003 inherited operations created by an unrelated type derivation.
16004 (Check_Overriding_Indicator): When checking for the presence of "null"
16005 in a procedure, ensure that the queried node is a procedure
16007 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
16008 type when the formal is an access to variable.
16009 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
16010 (Analyze_Task_Type): Same addition
16011 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
16012 provide navigation capabilities for entries.

16019 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
16020 inherited from an interface ancestor by another interface in the
16021 context of an instance as 'late'.
16022 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
16023 of a call to a function that dispatches on access result.
16024 (Check_Dispatching_Operation): In case of late overriding of a primitive
16025 that covers abstract interface subprograms we register it in all the
16026 secondary dispatch tables associated with abstract interfaces.
16027 (Check_Dispatching_Call): Add check that a dispatching call is not made
16028 to a function with a controlling result of a limited type. This is a
16029 current implementation restriction.
16030 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
16031 (Check_Dispatching_Operation): Do no emit a warning if the controlling
16032 argument is an interface type that is a generic formal.
16033 (Is_Interface_Subprogram): Removed.
16034 (Check_Dispatching_Operation): If the subprogram is not a dispatching
16035 operation, check the formals to handle the case in which it is
16036 associated with an abstract interface type.

16039 Ed Schonberg <schonberg@adacore.com>

16054 Javier Miranda <miranda@adacore.com>
16056 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
16057 subprogram type to provide better diagnostics in case of ambiguity.
16058 (Covers): Handle coverage of formal and actual anonymous access types in
16059 the context of generic instantiation.
16060 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
16061 abstract interface types; this is required to handle concurrent types
16062 with discriminants and abstract interface types.
16063 (Covers): Include type coverage of both regular incomplete subtypes and
16064 incomplete subtypes of incomplete type visibles through a limited with

16076 Add missing continuation marks in error msgs
16077 (Unqualify): New function for removing zero or more levels of
16078 qualification from an expression. There are numerous places where this
16079 ought to be used, but we currently only deal properly with zero or one
16081 (In_Instance); The analysis of the actuals in the instantiation of a
16082 child unit is not within an instantiation, even though the parent
16083 instance is on the scope stack.
16084 (Safe_To_Capture_Value): Exclude the case of variables that are
16086 (Check_Obsolescent): Removed
16087 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
16088 is an aliased view, even when rewritten as a reference to the target
16089 object in an assignment.
16090 (Get_Subprogram_Entity): New function
16091 (Known_To_Be_Assigned): New function
16092 (Type_Access_Level): Compute properly the access level of a return

16099 has a null exclusion depending on its Nkind.
16100 Change Is_Lvalue to May_Be_Lvalue
16101 (May_Be_Lvalue): Extensive additional code to deal with subprogram
16102 arguments (IN parameters are not Lvalues, IN OUT parameters are).
16103 (Safe_To_Capture_Value): Extend functionality so it can be used for
16104 the current value condition case.
16105 (Has_Compatible_Alignment): New function
16106 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
16107 objects to handle the Ada 2005 case, where aliasedness no longer implies
16108 that the object is constrained. In particular, for dereferenced names,
16109 the designated object must be assumed to be unconstrained.
16110 (Kill_Current_Values): Properly deal with the case where we encounter
16111 a loop in the scope chain.
16112 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
16114 (Compile_Time_Constraint_Error): Improve error message in error case

16122 * s-osinte-tru64.adb:
16123 Mark Asm statements Volatile to prevent warnings (seems a
16124 reasonable change anyway)
16127 * s-mastop-irix.adb: Add Volatile to Asm statements
16128 Suppresses warning, and seems appropriate in any case
16130 * s-osinte-vms.adb: Add Volatile to Asm statement

16773 the pointer to the allocated object to reference the corresponding
16774 secondary dispatch table.
16775 (Expand_N_Op_Divide): Allow 64 bit divisions by small power of 2,

16828 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
16829 type we cannot inherit the primitive operations; we inherit the
16830 Corresponding_Record_Type (which has the list of primitive operations).
16831 (Check_Anonymous_Access_Types): When creating anonymous access types for
16832 access components, use Rewrite in order to preserve the tree structure,
16834 (Analyze_Object_Declaration): For limited types with access
16835 discriminants with defaults initialized by an aggregate, obtain
16836 subtype from aggregate as for other mutable types.
16837 (Derived_Type_Declaration): If the derived type is a limited interface,
16838 set the corresponding flag (Is_Limited_Record is not sufficient).

16847 2006-02-17 Javier Miranda <miranda@adacore.com>
16849 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
16850 abstract interface type, the static analysis is not enough to know if
16851 the interface is implemented or not by the source tagged type. Hence
16852 we must pass the work to the expander to generate the required code to
16853 evaluate the conversion at run-time.
16854 (Resolve_Equality_Op): Do not apply previous
16855 transformation if expansion is disasbled, to prevent anomalies when
16856 locating global references in a generic unit.

17036 table to take advantage of the 16 priority levels available on Windows
17037 2000 and XP. On NT4 there are only 7 priority levels, this is properly

17599 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
17600 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
17601 aggregate when it is part of an object declaration.
17602 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
17603 constrains discriminants of its parent, add explicitly the discriminant
17604 constraints of the ancestor by retrieving them from the
17605 stored_constraint of the parent.
17607 2006-02-13 Robert Dewar <dewar@adacore.com>
17609 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
17610 attribute Mechanism_Code is applied to renamed subprogram, modify
17611 prefix to point to base subprogram.
17612 Max/Min attributes now violate Restriction No_Implicit_Conditionals
17614 * sinfo.ads: Document that Mechanism_Code cannot be applied to
17615 renamed subprograms so that the front-end must replace the prefix
17618 2006-02-13 Javier Miranda <miranda@adacore.com>
17619 Gary Dismukes <dismukes@adacore.com>
17621 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
17622 availability of RE_Interface_Tag.
17623 (Build_Initialization_Call): Fix wrong access to the discriminant value.
17624 (Freeze_Record_Type): Do not generate the tables associated with
17625 timed and conditional dispatching calls through synchronized
17626 interfaces if compiling under No_Dispatching_Calls restriction.
17627 When compiling for Ada 2005, for a nonabstract
17628 type with a null extension, call Make_Controlling_Function_Wrappers
17629 and insert the wrapper function declarations and bodies (the latter
17630 being appended as freeze actions).
17631 (Predefined_Primitive_Bodies): Do not generate the bodies of the
17632 predefined primitives associated with timed and conditional
17633 dispatching calls through synchronized interfaces if we are
17634 compiling under No_Dispatching_Calls.
17635 (Build_Init_Procedure): Use RTE_Available to check if a run-time
17636 service is available before generating a call.
17637 (Make_Controlling_Function_Wrappers): New procedure.
17638 (Expand_N_Full_Type_Declaration): Create a class-wide master for
17639 access-to-limited-interfaces because they can be used to reference
17640 tasks that implement such limited interface.
17641 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
17642 procedure spec and body of the Offset_To_Top function that is generated
17643 when the parent of a type with discriminants has secondary dispatch
17645 (Init_Secondary_Tags): Handle the case in which the parent of the type
17646 containing secondary dispatch tables has discriminants to generate the
17647 correct arguments to call Set_Offset_To_Top.
17648 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
17650 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
17651 Add Wide_[Wide_]Expanded_Name.
17652 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
17653 the same functionality of Get_Prim_Op_Address but applied to predefined
17654 primitive operations because the pointers to the predefined primitives
17655 are now saved in a separate table.
17656 (Parent_Size): Modified to get access to the separate table of primitive
17657 operations or the parent type.
17658 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
17659 functionality of Set_Prim_Op_Address but applied to predefined primitive
17661 (Set_Signature): New subprogram used to store the signature of a DT.
17662 (Displace): If the Offset_To_Top value is not static then call the
17663 function generated by the expander to get such value; otherwise use
17664 the value stored in the table of interfaces.
17665 (Offset_To_Top): The type of the actual has been changed to Address to
17666 give the correct support to tagged types with discriminants. In this
17667 case this value is stored just immediately after the tag field.
17668 (Set_Offset_To_Top): Two new formals have been added to indicate if the
17669 offset_to_top value is static and hence pass this value to the run-time
17670 to store it in the table of interfaces, or else if this value is dynamic
17671 and then pass to the run-time the address of a function that is
17672 generated by the expander to provide this value for each object of the
17675 * rtsfind.ads (Default_Prin_Op_Count): Removed.
17676 (Default_Prim_Op_Count): New entity
17677 (Get_Predefined_Prim_Op_Address): New entity
17678 (Set_Predefined_Prim_Op_Address): New entity
17679 (RE_Set_Signature): New entity
17681 2006-02-13 Thomas Quinot <quinot@adacore.com>
17682 Ed Schonberg <schonberg@adacore.com>
17684 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
17685 Make_Adjust_Call done for a newly-allocated object.
17687 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
17688 in a subprogram are wrapped in a cleanup block, indicate that the
17689 subprogram contains an inner block with an exception handler.
17690 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
17691 Adjust call is for a newly-allocated object. In that case we must not
17692 assume that the finalization list chain pointers are correct (since they
17693 come from a bit-for-bit copy of the original object's pointers) so if
17694 the attach level would otherwise be zero (no change), we set it to 4
17695 instead to cause the pointers to be reset to null.
17697 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
17698 reset chain pointers to null.
17700 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17702 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
17703 string, and the context requires a loop for the assignment (e.g.
17704 because the left-hand side is packed), generate a unique name for the
17705 temporary that holds the string, to prevent spurious name clashes.
17707 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17708 Javier Miranda <miranda@adacore.com>
17709 Robert Dewar <dewar@adacore.com>
17710 Gary Dismukes <dismukes@adacore.com>
17712 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
17713 return unconstrained arrays.
17715 (Expand_Call): An indirect call through an access parameter of a
17716 protected operation is not a protected call.
17717 Add circuit to raise CE in Ada 2005 mode following call
17718 to Raise_Exception.
17719 (Register_DT_Entry): Do nothing if
17720 the run-time does not give support to abstract interfaces.
17721 (Freeze_Subprogram): In case of dispatching operations, do not generate
17722 code to register the operation in the dispatch table if the source
17723 is compiled with No_Dispatching_Calls.
17724 (Register_Predefined_DT_Entry): Generate code that calls the new
17725 run-time subprogram Set_Predefined_Prim_Op_Address instead of
17726 Set_Prim_Op_Address.
17728 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
17729 on array assignments if the right-hand side is a function call that has
17730 been inlined. Check is performed on the assignment in the block.
17731 (Process_Bounds): If bounds and range are overloaded, apply preference
17732 rule for root operations to disambiguate, and diagnose true ambiguity.
17733 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
17734 a tag-indeterminate right-hand side even when Expander_Active is True.
17735 Needed to ensure that dispatching calls to T'Input are allowed and
17736 get the tag of the target class-wide object.
17738 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
17739 an inherited primitive operation that already overrides several
17740 abstract interface primitives. For transitivity, the new entity must
17741 also override all the abstract interface primitives covered by the
17742 inherited overriden primitive.
17743 Emit warning if new entity differs from homograph in same scope only in
17744 that one has an access parameter and the other one has a parameter of
17745 a general access type with the same designated type, at the same
17746 position in the signature.
17747 (Make_Inequality_Operator): Use source locations of parameters and
17748 subtype marks from corresponding equality operator when creating the
17749 tree structure for the implicit declaration of "/=". This does not
17750 change anything in behaviour except that the decoration of the
17751 components of the subtree created for "/=" allows ASIS to get the
17752 string images of the corresponding identifiers.
17753 (Analyze_Return_Statement): Remove '!' in warning message.
17754 (Check_Statement_Sequence): Likewise.
17755 (Analyze_Subprogram_Body): For an access parameter whose designated type
17756 is an incomplete type imported through a limited_with clause, use the
17757 type of the corresponding formal in the body.
17758 (Check_Returns): Implicit return in No_Return procedure now raises
17759 Program_Error with a compile time warning, instead of beging illegal.
17760 (Has_Single_Return): Function returning unconstrained type cannot be
17761 inlined if expression in unique return statement is not an identifier.
17762 (Build_Body_To_Inline): It is possible to inline a function call that
17763 returns an unconstrained type if all return statements in the function
17764 return the same local variable. Subsidiary procedure Has_Single_Return
17765 verifies that the body conforms to this restriction.
17767 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
17768 same type, and one of them is of an anonymous access type, convert
17769 the other operand to it, so that this is a valid binary operation for
17771 (Resolve_Type_Conversion): Handle subtypes of protected types and
17772 task types when accessing to the corresponding record type.
17773 (Resolve_Allocator): Add '\' in 2-line warning message.
17774 Remove '!' in warning message.
17775 (Resolve_Call): Add '\' in 2-line warning message.
17776 (Valid_Conversion): Likewise.
17777 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
17778 resulting type may be an access type with an implicit dereference.
17779 Obtain the proper component from the designated type.
17780 (Make_Call_Into_Operator): Handle properly a call to predefined equality
17781 given by an expanded name with prefix Standard, when the operands are
17782 of an anonymous access type.
17783 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
17784 Explicit_Dereference and Resolve_Selected_Component, to verify that the
17785 prefix of the expression is not of an incomplete type. Allows full
17786 diagnoses of all semantic errors.
17787 (Resolve_Actuals): If the actual is an allocator whose directly
17788 designated type is a class-wide interface we build an anonymous
17789 access type to use it as the type of the allocator. Later, when
17790 the subprogram call is expanded, if the interface has a secondary
17791 dispatch table the expander will add a type conversion to force
17792 the displacement of the pointer.
17793 (Resolve_Call): If a function that returns an unconstrained type is
17794 marked Inlined_Always and inlined, the call will be inlined and does
17795 not require the creation of a transient scope.
17796 (Check_Direct_Boolean_Op): Removed
17797 (Resolve_Comparison_Op): Remove call to above
17798 (Resolve_Equality_Op): Remove call to above
17799 (Resolve_Logical_Op): Inline above, since this is only call.
17800 (Valid_Conversion): Handle properly conversions between arrays of
17801 convertible anonymous access types.
17804 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
17805 the literal in an unchecked conversion, because GCC 4.x needs a static
17806 value for a string bound.
17808 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17809 Hristian Kirtchev <kirtchev@adacore.com>
17811 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
17812 components of the corresponding record, take into account component
17813 definitions that are access definitions.
17814 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
17815 procedure is not considered a dispatching call and will be expanded
17818 2006-02-13 Javier Miranda <miranda@adacore.com>
17820 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
17821 controlling argument of the dispatching call is an abstract interface
17822 class-wide type then we use it directly.
17823 Check No_Dispatching_Calls restriction.
17824 (Default_Prim_Op_Position): Remove the code that looks for the last
17825 entity in the list of aliased subprograms. This code was wrong in
17827 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
17828 when the source is compiled with the No_Dispatching_Calls restriction.
17829 (Init_Predefined_Interface_Primitives): No need to inherit primitives
17830 if we are compiling with restriction No_Dispatching_Calls.
17831 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
17832 subprograms if we are compiling under No_Dispatching_Calls restriction.
17833 (Make_DT): Generate a dispatch table with a single dummy entry if
17834 we are compiling with the No_Dispatching_Calls restriction. In
17835 addition, in this case we don't generate code that calls to the
17836 following run-time subprograms: Set_Type_Kind, Inherit_DT.
17837 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
17838 of this subprogram if compiling with the No_Dispatching_Calls
17840 (Expand_Type_Conversion): Instead of using the actual parameter,
17841 the argument passed as parameter to the conversion function was
17842 erroneously referenced by the expander.
17843 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
17844 Set_Predefined_Primitive_Op_Address and Set_Signature.
17845 (Expand_Dispatching_Call): Generate call to
17846 Get_Predefined_Prim_Op_Address for predefined primitives.
17847 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
17848 predefined primitives.
17849 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
17850 primitives we reserve one dummy entry to ensure that the tag does not
17851 point to some memory that is associated with some other object. In
17852 addition, remove all the old code that generated the assignments
17853 associated with the signature of the dispatch table and replace them
17854 by a call to the new subprogram Set_Signature.
17855 (Set_All_DT_Position): Change the algorithm because now we have a
17856 separate dispatch table associated with predefined primitive operations.
17857 (Expand_Interface_Conversion): In case of non-static offset_to_top
17858 add explicit dereference to get access to the object after the call
17859 to displace the pointer to the object.
17860 (Expand_Interface_Thunk): Modify the generation of the actual used
17861 in the calls to the run-time function Offset_To_Top to fulfil its
17863 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
17865 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17867 * exp_dist.adb (Copy_Specification): For access parameters, copy
17868 Null_Exclusion flag, which will have been set for stream subprograms
17871 2006-02-13 Pascal Obry <obry@adacore.com>
17873 * expect.c (__gnat_expect_portable_execvp): New implementation. The
17874 previous implementation was using the C runtime spawnve routine but
17875 the corresponding wait was using directly the Win32 API. This was
17876 causing some times a lock when waiting for an event using
17877 WaitForSingleObject in __gnat_waitpid. This new implementation uses
17878 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
17879 API fixes this problem.
17881 2006-02-13 Robert Dewar <dewar@adacore.com>
17883 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

17891 array reference that is an explicit dereference, mark the converted
17892 (packed) array reference as analyzed to prevent a forthcoming
17893 reanalysis from resetting its type to the original (non-packed) array

17897 Javier Miranda <miranda@adacore.com>
17898 Eric Botcazou <ebotcazou@adacore.com>
17900 * exp_util.ads, exp_util.adb (Find_Prim_Op,
17901 Is_Predefined_Primitive_Operation): When
17902 searching for the predefined equality operator, verify that operands
17903 have the same type.
17904 (Is_Predefined_Dispatching_Operation): Remove the code that looks
17905 for the last entity in the list of aliased subprograms. This code
17906 was wrong in case of renamings.
17907 (Set_Renamed_Subprogram): New procedure
17908 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
17909 Exp_Type constant computed when entering this subprogram.

17911 (OK_To_Do_Constant_Replacement): New function
17912 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
17913 (Side_Effect_Free): An attribute reference 'Input is not free of
17914 side effect, unlike other attributes that are functions. (from code
17916 (Remove_Side_Effects): Expressions that involve packed arrays or records
17917 are copied at the point of reference, and therefore must be marked as
17918 renamings of objects.
17919 (Is_Predefined_Dispatching_Operation): Return false if the operation is
17920 not a dispatching operation.
17923 (Remove_Side_Effects): Lift enclosing type conversion nodes for
17924 elementary types in all cases.
17926 2006-02-13 Javier Miranda <miranda@adacore.com>
17928 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
17929 task types when accessing to the corresponding record type.
17930 Remove '!' in warning message.
17932 2006-02-13 Olivier Hainque <hainque@adacore.com>
17934 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
17935 to avoid useless and space inefficient overalignments on targets where
17936 Max_Alignment is larger than 16.
17938 2006-02-13 Pascal Obry <obry@adacore.com>
17940 * g-catiio.adb (Sec_Number): New type used to compute the number of
17941 seconds since 1-1-1970.
17942 (Image) [Natural]: The parameter was an Integer, as we can't deal with
17943 negative numbers (years, months...) it is better to have a Natural here.
17945 (Image) [Number]: Change parameter from Long_Integer to Number.
17946 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
17947 overflow for dates past year 2038.
17949 2006-02-13 Matthew Heaney <heaney@adacore.com>
17951 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
17954 2006-02-13 Arnaud Charlet <charlet@adacore.com>
17956 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
17958 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
17959 finalization can occur normally.
17961 2006-02-13 Vincent Celier <celier@adacore.com>
17963 * gnatcmd.adb (Rules_Switches): New table
17964 (Add_To_Rules_Switches): New procedure
17965 (GNATCmd): For command CHECK, put all options following "-rules" in the
17966 Rules_Switches table. Append these -rules switches after the -cargs
17969 2006-02-13 Robert Dewar <dewar@adacore.com>
17971 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
17972 These two cases were generating incorrect output, and if this unit
17973 was built with checks on, generated a discriminant mismatch constraint
17976 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17977 Robert Dewar <dewar@adacore.com>
17979 * lib-xref.adb (Get_Type_Reference): For a private type whose full
17980 view is an array type, indicate the component type as well, for
17981 navigation purposes.
17982 (Generate_Reference): Don't consider array ref on LHS to be a case
17983 of violating pragma Unreferenced.
17984 Do not give Ada 2005 warning except on real reference.
17986 2006-02-13 Vincent Celier <celier@adacore.com>
17988 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
17989 main source, add switch -mdebug-main=_ada_ so that the executable can
17990 be debugged by the standard VMS debugger.
17991 (Gnatmake): Set No_Main_Subprogram to True when there is no main
17992 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
17993 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
17994 of the last source, as the binding and linking phases are never
17996 Set all executable obsolete when rebuilding a library.
17998 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
18001 2006-02-13 Javier Miranda <miranda@adacore.com>
18004 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
18005 code to improve the error message reported when the program has
18006 declarations of abstract interface types and it is not compiled with
18007 the -gnat05 switch.
18008 (P_Access_Definition): Reorganize the code to improve the error
18009 message reported when the new Ada 2005 syntax for anonymous
18010 access types is used and the program is not compiled with the

18027 the standard naming data.
18029 2006-02-13 Vincent Celier <celier@adacore.com>
18031 * prj.ads (Error_Warning): New enumeration type
18033 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
18034 unknown, use the location of the project to report the error.
18035 (When_No_Sources): New global variable
18036 (Report_No_Ada_Sources): New procedure
18037 (Check): New parameter When_No_Sources. Set value of global variable

18045 Call Prj.Proc.Process with parameter When_No_Sources.
18047 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
18048 Call Recursive_Check with parameter When_No_Sources.

18050 Prj.Nmsc.Check with parameter When_No_Sources.
18051 (Process): New parameter When_No_Sources. Call Check with parameter

18063 When removing nodes (attributes Source_Dirs, Source_Files,
18064 Source_List_File and package Naming), save the comments and attach the
18065 saved comments to the newly created nodes.
18066 Do not add a with clause for the naming package if one already exists.

18074 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
18075 aliased entities to look for the overriden abstract interface
18077 (Is_Interface_Subprogram): Complete documentation.
18078 (Check_Dispatching_Operation): Do not generate code to register the
18079 operation in the dispatch table if the source is compiled with
18080 restriction No_Dispatching_Calls.
18081 (Override_Dispatching_Operation): Check for illegal attempt to override
18082 No_Return procedure with procedure that is not No_Return
18083 (Check_Dispatching_Call): Suppress the check for an abstract operation
18084 when the original node of an actual is a tag-indeterminate attribute
18085 call, since the attribute, which must be 'Input, can never be abstract.
18086 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
18087 call to the Input attribute (even when rewritten).
18088 (Propagate_Tag): Augment comment to indicate the possibility of a call
18089 to an Input attribute.
18091 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
18092 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
18094 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
18095 No_Wide_Characters is no longer partition-wide
18096 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
18099 2006-02-13 Douglas Rupp <rupp@adacore.com>
18101 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
18103 2006-02-13 Javier Miranda <miranda@adacore.com>
18105 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
18106 handles default-initialized components to keep separate the management
18107 of this feature but also avoid the unrequired resolution and
18108 expansion of components that do not have partially initialized
18110 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
18111 (Check_Bounds): Likewise.
18112 (Check_Length): Likewise.
18114 2006-02-13 Javier Miranda <miranda@adacore.com>
18115 Ed Schonberg <schonberg@adacore.com>
18117 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
18118 abstract interface type call analyze_and_resolve to expand the type
18119 conversion into the corresponding displacement of the
18120 reference to the base of the object.
18121 (Eval_Attribute, case Width): For systems where IEEE extended precision
18122 is supported, the maximum exponent occupies 4 decimal digits.
18123 (Accessibility_Message): Add '\' in 2-line warning message.
18124 (Resolve_Attribute): Likewise.
18125 (case Attribute_Access): Significantly revise checks
18126 for illegal access-to-subprogram Access attributes to properly enforce
18127 the rules of 3.10.2(32/2).
18128 Diagnose use of current instance with an illegal attribute.
18130 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
18132 (Enclosing_Generic_Unit): New function to return a node's innermost
18133 enclosing generic declaration node.
18134 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
18135 (Type_Access_Level): The accessibility level of anonymous acccess types
18136 associated with discriminants is that of the current instance of the
18137 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
18138 (Compile_Time_Constraint_Error): Handle case of conditional expression.
18139 (Kill_Current_Values_For_Entity): New function
18140 (Enter_Name): Change formal type to Entity_Id
18142 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
18143 Ed Schonberg <schonberg@adacore.com>
18144 Gary Dismukes <dismukes@adacore.com>
18146 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
18147 Analyze_Compilation_Unit.
18148 Detect and warn on redundant with clauses detected in a package spec
18149 and/or body when -gnatwr is used.
18150 (Analyze_Context): Analyze config pragmas before other items
18151 (Install_Context_Items): Don't analyze config pragmas here
18152 (Install_Limited_Withed_Unit): Set limited entity of package in
18153 with_clause so that cross-reference information or warning messages on
18154 unused packages can be properly generated
18155 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
18156 has Error_Posted set. Prevent infinite loops in illegal programs.
18157 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
18158 to the point of the error test requiring the current unit to be private.
18159 This ensures that private with clauses are not exempted from the basic
18160 checking for being a descendant of the same library unit parent as a
18161 withed private descendant unit.
18162 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
18163 handle private with clauses properly, as well as to account for cases
18164 where the withed unit is a public descendant of a private ancestor
18165 (in which case the current unit must be a descendant of the private
18166 ancestor's parent). The spec comments were updated accordingly. Also,
18167 the old error message in this subprogram was replaced with error
18168 messages that mirror the errors tested and reported by
18169 Check_Private_Child_Unit.
18170 Parameter and variable names improved for readability.
18171 (Install_Limited_Context_Clauses): Remove test for a withed unit being
18172 private as the precondition for calling
18173 Check_Private_Limited_Withed_Unit since that subprogram has been
18174 revised to test public units as well as private units.

18178 Ed Schonberg <schonberg@adacore.com>
18179 Javier Miranda <miranda@adacore.com>
18181 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
18182 that Scope_Stack.First = 1.
18183 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18184 were not always properly handled previously.
18185 (Formal_Entity): Complete rewrite, to handle properly some complex case
18186 with multiple levels of parametrization by formal packages.
18187 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
18188 to the corresponding derived type declaration for proper semantics.
18190 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
18191 (Check_Component): Enforce restriction on components of
18192 unchecked_unions: a component in a variant cannot contain tasks or
18194 (Unchecked_Union): Allow nested variants and multiple discriminants, to
18196 Add pragma Ada_2005 (synonym for Ada_05)
18197 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18198 were not always properly handled previously.
18199 Document that pragma Propagate_Exceptions has no effect
18200 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
18201 (Set_Convention_From_Pragma): Check that if a convention is
18202 specified for a dispatching operation, then it must be
18203 consistent with the existing convention for the operation.
18204 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
18205 longer required to specify an vtable-ptr component in the record. For
18206 compatibility reasons we leave the support for the previous definition.
18207 (Analyze_Pragma, case No_Return): Allow multiple arguments
18209 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
18210 non-overrideen inherited operation with a controlling result as
18211 illegal only its implicit declaration comes from the derived type
18212 declaration of its result's type.
18213 (Check_Possible_Deferred_Completion): Relocate the object definition
18214 node of the subtype indication of a deferred constant completion rather
18215 than directly analyzing it. The analysis of the generated subtype will
18216 correctly decorate the GNAT tree.
18217 (Record_Type_Declaration): Check whether this is a declaration for a
18218 limited derived record before analyzing components.
18219 (Analyze_Component_Declaration): Diagnose record types not explicitly
18220 declared limited when a component has a limited type.
18221 (Build_Derived_Record_Type): Code reorganization to check if some of
18222 the inherited subprograms of a tagged type cover interface primitives.
18223 This check was missing in case of a full-type associated with a private
18225 (Constant_Redeclaration): Check that the subtypes of the partial and the
18226 full view of a constrained deferred constant statically match.
18227 (Mentions_T): A reference to the current type in an anonymous access
18228 component declaration must be an entity name.
18229 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
18230 class_wide type to refer to full type, not to the incomplete one.
18231 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
18232 available. Required to give support to the certified run-time.
18233 (Analyze_Component_Declaration): In case of anonymous access components
18234 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
18235 (Process_Discriminants): For an access discriminant, use the
18236 discriminant specification as the associated_node_for_itype, to
18237 simplify accessibility checks.
18239 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18240 Javier Miranda <miranda@adacore.com>
18242 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
18243 abstract interpretations on an operator, remove interpretations that
18244 yield Address or a type derived from it, if one of the operands is an
18246 (Try_Object_Operation.Try_Primitive_Operation,
18247 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
18248 location when creating the new reference to a primitive or class-wide
18249 operation as a part of rewriting a subprogram call.
18250 (Try_Primitive_Operations): If context requires a function, collect all
18251 interpretations after the first match, because there may be primitive
18252 operations of the same type with the same profile and different return
18253 types. From code reading.
18254 (Try_Primitive_Operation): Use the node kind to choose the proper
18255 operation when a function and a procedure have the same parameter
18257 (Complete_Object_Operation): If formal is an access parameter and prefix
18258 is an object, rewrite as an Access reference, to match signature of
18259 primitive operation.
18260 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
18261 by an expanded name with prefix Standard, when the operands are of an
18262 anonymous access type.
18263 (Remove_Abstract_Operations): If the operation is abstract because it is
18264 inherited by a user-defined type derived from Address, remove it as
18265 well from the set of candidate interpretations of an overloaded node.
18266 (Analyze_Membership_Op): Membership test not applicable to cpp-class
18269 2006-02-13 Bob Duff <duff@adacore.com>
18271 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
18272 redundant use clauses.
18273 In particular, if the scope of two use clauses overlaps, but one is not
18274 entirely included in the other, we should not warn. This can happen
18275 with nested packages.
18276 (Analyze_Subprogram_Renaming): Protect the compiler against previously
18277 reported errors. The bug was reported when the compiler was built
18278 with assertions enabled.
18279 (Find_Type): If the node is a 'Class reference and the prefix is a
18280 synchronized type without a corresponding record, return the type
18283 2006-02-13 Javier Miranda <miranda@adacore.com>
18285 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
18286 if this is the full-declaration associated with a private declaration
18287 that implement interfaces, then the private type declaration must be
18289 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
18290 as aliased. The use of the 'access attribute is not available for such
18291 object (for this purpose the object should be explicitly marked as
18292 aliased, but being an anonymous type this is not possible).
18294 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18295 Robert Dewar <dewar@adacore.com>
18297 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
18298 compilation unit is an elaboration scope.
18299 (Add_Task_Proc): Add '\' in 2-line warning message.
18300 (Activate_All_Desirable): Deal with case of unit with'ed by parent
18302 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18303 Javier Miranda <miranda@adacore.com>
18305 * sem_type.adb (Write_Overloads): Improve display of candidate
18307 (Add_One_Interp): Do not add to the list of interpretations aliased
18308 entities corresponding with an abstract interface type that is an
18309 immediate ancestor of a tagged type; otherwise we have a dummy
18310 conflict between this entity and the aliased entity.
18311 (Disambiguate): The predefined equality on universal_access is not
18312 usable if there is a user-defined equality with the proper signature,
18313 declared in the same declarative part as the designated type.
18314 (Find_Unique_Type): The universal_access equality operator defined under
18315 AI-230 does not cover pool specific access types.
18316 (Covers): If one of the types is a generic actual subtype, check whether
18317 it matches the partial view of the other type.
18319 2006-02-13 Thomas Quinot <quinot@adacore.com>
18321 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
18322 line. This is necessary to allow In_Extended_Main_Unit to provide
18323 correct results for itypes while writing out expanded source.
18324 (Close_File): No need to update the source_index_table here since it's
18325 now done for each line.
18327 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18328 Robert Dewar <dewar@adacore.com>
18330 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
18331 preserve the source unit where the itype is declared, and prevent a
18333 (Note_Implicit_Run_Time_Call): New procedure
18334 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
18337 * sprint.ads: Document use of $ for implicit run time routine call
18339 2006-02-13 Quentin Ochem <ochem@adacore.com>
18341 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
18344 2006-02-13 Bob Duff <duff@adacore.com>
18346 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
18347 Scan_Unsigned, so we do not scan leading blanks and sign twice.
18348 Integer'Value("- 5") and Integer'Value("-+5") now correctly
18349 raise Constraint_Error.
18351 * s-vallli.adb (Scan_Long_Long_Integer): Call
18352 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
18353 do not scan leading blanks and sign twice.
18354 Integer'Value("- 5") and Integer'Value("-+5") now correctly
18355 raise Constraint_Error.
18357 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
18358 Scan_Long_Long_Unsigned): Split out most of the processing from
18359 Scan_Long_Long_Unsigned out into
18360 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
18361 This prevents scanning leading blanks and sign twice.
18362 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
18365 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
18366 out most of the processing from Scan_Unsigned out into
18367 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
18368 This prevents scanning leading blanks and sign twice.
18370 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
18371 use with Modular'Value attribute.
18372 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

18570 * a-taster.ads, a-taster.adb: New files.
18572 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
18573 link to the version that does nothing. This way the task termination
18574 routine is not executed twice for the environment task when finishing
18575 because of an unhandled exception.
18577 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
18578 handler because of an unhandled exception.
18580 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
18581 System.Tasking.Utilities instead of that in System.Tasking.Stages.

18586 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
18587 non-tasking version of the soft link for task termination. We do
18588 nothing since if we are using the non-tasking version it
18589 means that the task termination functionality is not used.
18590 (Null_Finalize_Global_List): Add this null version for the procedure
18591 in charge of finalizing the global list for controlled objects.
18592 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
18593 instead for handling run-time termination in a more flexible way.
18594 (Adafinal_NT): This new procedure will take care of finalizing the
18595 global list for controlled objects if needed, but no tasking
18598 * s-tarest.adb (Task_Lock): Do not try to lock again the
18599 Global_Task_Lock if we already own it. Otherwise, we get blocked in
18600 some run-time operations.
18601 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
18602 until all nested locks have been released.
18603 (Task_Wrapper): Call the fall-back task termination handler. It
18604 applies to all tasks but the environment task.
18605 (Finalize_Global_Tasks): Add the call for the task termination
18606 procedure for the environment task.
18607 (Task_Wrapper): suppress warnings around declaration of
18608 Secondary_Stack_Address.
18610 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
18611 moved to the Common_ATCB record.
18612 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
18613 Common_ATCB record.
18614 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
18615 Common_ATCB record.
18617 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
18618 Fall_Back_Handler, and Specific_Handler.
18620 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
18621 defined in Ada.Task_Termination, to avoid circular dependencies.
18622 (Termination_Handler): Redefine this type here, alredy defined in
18623 Ada.Task_Termination, for avoiding circular dependencies.
18624 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
18625 for storing task termination handlers. In addition,
18626 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
18627 Common_ATCB because it is used by both the regular and the restricted
18629 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
18630 Common_ATCB because it is used by both the regular and the restricted
18632 (Common_ATCB): Added a dynamic task analyzer field.
18634 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
18635 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.

18637 tasks but the environment task.
18638 (Finalize_Global_Tasks): Call the task termination procedure for the
18639 environment task. The call to Finalize_Global_List is now performed
18640 using the soft links mechanism.
18641 (Task_Wrapper): added dynamic stack analysis.
18643 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
18644 potentially blocking operations has been moved from
18645 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
18646 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
18647 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
18648 this run-time check.
18650 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
18651 of task termination procedure.
18652 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
18653 link for the task termination procedure.

18694 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
18695 to the specification because the frontend generates code that uses this
18697 (Set_Interface_Table): Add missing assertion.
18698 Update documentation describing the run-time structure.
18699 (Displace): New subprogram that displaces the pointer to the object
18700 to reference one of its secondary dispatch tables.
18701 (IW_Membership): Modified to use the new table of interfaces.
18702 (Inherit_TSD): Modified to use the new table of interfaces.
18703 (Register_Interface_Tag): Use the additional formal to fill the
18704 contents of the new table of interfaces.
18705 (Set_Interface_Table): New subprogram that stores in the TSD the
18706 pointer to the table of interfaces.

18720 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
18721 in all the calls to Expand_Interface_Thunk. Instead of referencing the
18722 record component containing the tag of the secondary dispatch table we
18723 have to use the Offset_To_Top run-time function to get this information;
18724 otherwise if the pointer to the base of the object has been displace
18725 we get a wrong value if we use the 'position attribute.
18727 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
18728 all the calls to Expand_Interface_Thunk.
18729 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
18730 interfaces; hence the call to Set_Interface_Table was clearly wrong.

18732 ensure that the interfaces implemented by the ancestors are placed
18733 at the header of the generated list.
18734 (Expand_Interface_Conversion): Handle the case in which the displacement
18735 associated with the interface conversion is not statically known. In
18736 this case we generate a call to the new run-time subprogram Displace.

18738 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
18739 Get_Tagged_Kind and Set_Tagged_Kind.
18740 (Tagged_Kind): New function that determines the tagged kind of a type
18741 with respect to limitedness and concurrency and returns a reference to

18761 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
18762 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
18763 RE_TK_Tagged, RE_TK_Task.
18765 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
18766 Init_Secondary_Tags_Internal to allow its use with interface types and
18767 also to generate the code for the new additional actual required
18768 by Set_Offset_To_Top.
18769 (Build_Init_Statements): In case of components associated with abstract
18770 interface types there is no need to generate a call to its IP.
18771 (Freeze_Record_Type): Generate Select Specific Data tables only for
18773 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
18774 the bodies and specifications of the predefined primitive operations

18780 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
18781 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
18782 properly protected objects and attach handler in the case of the
18783 restricted profile.
18784 Move embeded package Select_Expansion_Utilities into a separate external
18786 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
18787 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
18788 (Build_K, Build_S_Assignment): New subprograms, part of the select
18789 expansion utilities.

18792 where the trigger is a dispatching procedure of a limited tagged type.
18794 2005-12-09 Olivier Hainque <hainque@adacore.com>
18796 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
18797 pointer initialization values. Make a SAVE_EXPR instead. Add comments
18798 about the use and expansion of SAVE_EXPRs in the various possible
18799 renaming handling cases.
18800 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
18801 abusing DECL_FCONTEXT.

18898 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
18899 and the assignment to a class-wide object, before the assignment we
18900 generate a run-time check to ensure that the tag of the Target is
18901 covered by the tag of the source.

18971 are implemented by the ancestors.
18972 (Derived_Type_Declaration): If the parent of the full-view is an
18973 interface perform a transformation of the tree to ensure that it has
18974 the same parent than the partial-view. This simplifies the job of the
18975 expander in order to generate the correct object layout, and it is
18976 needed because the list of interfaces of the full-view can be given in
18978 (Process_Full_View): The parent of the full-view does not need to be
18979 a descendant of the parent of the partial view if both parents are
18981 (Analyze_Private_Extension_Declaration): If declaration has an explicit
18982 "limited" the parent must be a limited type.
18983 (Build_Derived_Record_Type): A derived type that is explicitly limited
18984 must have limited ancestor and progenitors.
18985 (Build_Derived_Type): Ditto.

18996 (Process_Full_View): Improve the check for the "no hidden interface"
18997 rule as defined by AI-396.

19056 available user-specified stream attributes on limited parameters to
19057 also test the type directly rather than only its underlying type (for
19058 Ada 95) and, in the case of Ada 2005, to check that the user-specified
19059 attributes are visible at the point of the subprogram declaration.
19060 For Ada 2005, the error message is modified to indicate that the
19061 type's stream attributes must be visible (again, only for -gnat05).

19344 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
19345 it did not matter because we always rewrote a/=b to not(a=b).
19346 (Expand_Allocator_Expression): For an allocator expression whose nominal
19347 subtype is an unconstrained packed type, convert the expression to its
19348 actual constrained subtype.

19369 Allow optional = after -gnatm
19370 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
19371 longer sets Elaboration_Checks.

19523 object with an address clause into an indirect reference, drop the
19524 initializing expression.
19526 (STACK_CHECK_BUILTIN): Delete.
19527 (STACK_CHECK_PROBE_INTERVAL): Likewise.

19534 related): For a prefix that is a dereference of a fat or thin pointer,
19535 if there is an actual subtype provided by the front-end, use that
19536 subtype to build an actual type with bounds template.
19537 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
19538 is provided by the front-end, use that subtype to compute the size of
19539 the deallocated object.
19540 (gnat_to_gnu): When adding a statement into an elaboration procedure,
19541 check for a potential violation of a No_Elaboration_Code restriction.
19542 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
19543 with extra arguments to control whether to recurse through non-values
19544 and to let the caller know if the stabilization has succeeded.

19546 maybe_stabilize, for common uses without restriction on lvalues and
19547 without need to check for the success indication.

19549 pass false instead of 0 as the FORCE argument which is a bool.
19550 (Identifier_to_gnu): Remove checks ensuring that an renamed object
19551 attached to a renaming pointer has been properly stabilized, as no such
19552 object is attached otherwise.

19554 function uses the "target pointer" return mechanism.
19555 Reinstate conversion of the actual to the type of the formal
19556 parameter before any other specific treatment based on the passing
19557 mechanism. This turns out to be necessary in order for PLACEHOLDER
19558 substitution to work properly when the latter type is unconstrained.

19564 and to let the caller know if the stabilization has succeeded.
19566 * utils2.c (gnat_build_constructor): Only sort the fields for possible
19567 static output of record constructor if all the components are constant.
19568 (gnat_build_constructor): For a record type, sort the list of field
19569 initializers in increasing bit position order.
19570 Factor common code to build a storage type for an unconstrained object
19571 from a fat or thin pointer type and a constrained object type.
19572 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
19573 types variants, and process special cases of VIEW_CONVERT expressions
19574 as their NOP_EXPR counterpart to ensure we get to the
19575 CORRESPONDING_VARs associated with CONST_DECls.
19576 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
19577 on the right-hand side.
19579 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring

19582 are converting back to its original type.
19583 (convert) <JM input>: Fallthrough regular conversion code instead of
19584 extracting the object if converting to a type variant.
19585 (create_var_decl): When a variable has an initializer requiring code
19586 generation and we are at the top level, check for a potential violation
19587 of a No_Elaboration_Code restriction.
19588 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
19589 SIZE and SIZE_UNIT which we need for later back-annotations.

19591 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
19592 is an unchecked union.
19593 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
19594 (convert) <VIEW_CONVERT_EXPR>: When the types have the same

19774 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
19775 'Unrestricted_Access, if the designated type is an interface we

19778 Use Universal_Real instead of Long_Long_Float when we need a high
19779 precision float type for the generated code (prevents gratuitous

19781 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
19782 'Terminated for task interface class-wide objects. Generate a call to
19783 the predefined dispatching routine used to retrieve the _task_id from

19813 the return value into its actual subtype in order to help the backend

19844 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

20145 In addition some minor reorganization of the code has been done to
20146 leave it more clear.
20147 (Analyze_Type_Declaration): If type has previous incomplete tagged

20204 whose default is abstract because the object type itself is abstract.
20205 (Find_Type): If the type is incomplete and appears as the prefix of a
20206 'Class reference, it is tagged, and its list of primitive operations
20207 must be initialized properly.
20208 (Chain_Use_Clauses): When chaining the use clauses that appear in the
20209 private declaration of a parent unit, prior to compiling the private
20210 part of a child unit, find on the scope stack the proper parent entity
20211 on which to link the use clause.

20235 remove address operations.
20236 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
20237 statement to inhibit warning.
20238 (Resolve_Unary_Op): Do not produce a warning when
20239 processing an expression of the form -(A mod B)
20240 Use Universal_Real instead of Long_Long_Float when we need a high

20243 (Resolve_Concatenation_Arg): Improve error message when argument is an
20244 ambiguous call to a function that returns an array.
20245 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

21187 * checks.adb (Check_Needed): New procedure, deals with removing checks
21188 based on analysis of short-circuited forms. Also generates warnings for
21189 improper use of non-short-circuited forms.

21205 (Error_Msg_Warn): New variable for < insertion char.
21206 * prj-nmsc.adb: Implement new errout insertion char < (conditional
21208 (Check_For_Source): Change value of Source_Id only after the current
21209 source has been dealt with.
21211 2005-09-01 Robert Dewar <dewar@adacore.com>
21212 Doug Rupp <rupp@adacore.com>
21214 * exp_attr.adb: Handle vax fpt for 'Valid attribute

21220 Hristian Kirtchev <kirtchev@adacore.com>
21221 Javier Miranda <miranda@adacore.com>
21223 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
21224 from object notation, the original node is unanalyzed and carries no
21225 semantic information, so that accessiblity checks must be performed on
21226 the type of the actual itself.
21227 (Expand_N_Subprogram_Declaration): Change last actual parameter for
21228 compatibility with Build_Protected_Sub_Specification.
21229 (Check_Overriding_Inherited_Interfaces): Add suport to handle
21230 overloaded primitives.
21231 (Register_Interface_DT_Entry): Use the new name of the formal
21232 the the calls to Expand_Interface_Thunk
21234 * exp_dbug.ads: Augment comments on encoding of protected types to
21235 include the generation of dispatching subprograms when the type
21236 implements at least one interface.
21238 * lib.ads: Extend information in Load_Stack to include whether a given
21239 load comes from a Limited_With_Clause.
21241 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
21242 whether a potential circularity is harmless, because it includes units
21243 loaded through a limited_with clause. Extends previous treatment which
21244 did not handle properly arbitrary combinations of limited and
21245 non-limited clauses.
21247 2005-09-01 Nicolas Setton <setton@adacore.com>
21249 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
21250 to be encoded as typ___XBLU_lowerbound__upperbound instead of
21251 typ___XB_lowerbound__upperbound.
21253 2005-09-01 Thomas Quinot <quinot@adacore.com>
21255 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
21256 dummy access formal for RACW/RAS TypeCode TSS.
21257 (Build_TypeCode_Call): Do not generate dummy null access actual for
21258 calls to the TypeCode TSS.
21260 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21262 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
21263 fully qualified name, to distinguish instances with the same local name.
21265 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
21268 2005-09-01 Robert Dewar <dewar@adacore.com>

21273 2005-09-01 Jerome Lambourg <lambourg@adacore.com>
21275 * g-expect.adb (Non_Blocking_Spawn): Initialize the filters field to
21276 (Free): New deallocation procedure for filter elements
21277 (Close): Deallocate any existing filter for the concerned connection
21279 2005-09-01 Laurent Pautet <pautet@adacore.com>
21281 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
21282 position set is provided, we compute one in order to reduce the maximum
21283 length of the keys. This computation first selects a character
21284 position between 1 and the minimum length of the keys in order to
21285 avoid reducing one of the keys to an empty string.
21286 (Initialize, Compute): When the ratio V to K is too low, the algorithm
21287 does not converge. The initialization procedure now comes with a
21288 maximum number of iterations such that when exceeded, an exception is
21289 raised in Compute. The user can initialize this ratio to another value
21291 Reformating and updated headers.
21293 2005-09-01 Javier Miranda <miranda@adacore.com>
21295 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
21296 that given an entity T creates and returns an Itype that duplicates the
21297 contents of T. The returned Itype has the null-exclusion
21298 attribute set to True, and its Etype attribute references T
21299 to keep the association between the two entities.
21300 Update copyright notice
21302 * sem_aggr.adb (Check_Can_Never_Be_Null,
21303 Aggregate_Constraint_Checks, Resolve_Aggregate,
21304 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
21306 * sem_ch5.adb (Analyze_Assignment): Code cleanup.
21308 2005-09-01 Gary Dismukes <dismukes@adacore.com>
21309 Robert Dewar <dewar@adacore.com>
21310 Hristian Kirtchev <kirtchev@adacore.com>
21312 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to

21317 Call Set_Result_Definition instead of Set_Subtype_Mark.
21318 (P_Subprogram_Specification): Add parsing of anonymous access result
21319 plus null exclusions. Call Set_Result_Definition instead of
21322 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
21323 (P_Access_Type_Definition): Add parsing for an anonymous access result
21324 subtype, plus parsing for null exclusions. Call Set_Result_Definition
21325 instead of Set_Subtype_Mark.
21327 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
21328 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
21329 (Result_Definition): New function for N_Function_Specifications.
21330 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
21331 N_Function_Specification.
21332 (Set_Null_Exclusion_Present): Allow this flag for
21333 N_Function_Specification.
21334 (Set_Result_Definition): New procedure for N_Function_Specifications.
21335 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
21336 and N_Function_Specification.
21338 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
21339 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
21340 Add support for LIMITED NEW for Ada 2005 AI-419
21341 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
21342 syntax for anonymous access results.
21343 Replace Subtype_Mark field by Result_Definition in
21344 N_Function_Specification and N_Access_Definition specs.
21345 Add Null_Exclusion_Present to spec of N_Function_Specification.
21346 (Result_Definition): New function for N_Function_Specification and
21347 N_Access_Function_Definition.
21348 (Set_Result_Definition): New procedure for N_Function_Specification and
21349 N_Access_Function_Definition.
21351 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
21352 Result_Definition for cases of N_Access_Function_Definition and
21353 N_Function_Specification.
21354 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
21356 2005-09-01 Vincent Celier <celier@adacore.com>
21358 * lib-writ.adb: Update Copyright notice
21359 (Write_With_Lines): On platforms where file names are case-insensitive,
21360 record the file names in lower case.
21361 (Write_ALI): For D lines, on platforms where file names are
21362 case-insensitive, record the file names in lower case.
21364 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21365 Emmanuel Briot <briot@adacore.com>
21367 * lib-xref.adb (Output_Overridden_Op): Display information on
21368 overridden operation.
21370 * lib-xref.ads: Add documentation on overridden operations.
21372 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
21375 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
21376 overriding entity information.

21380 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
21381 including those that are inherited.
21383 2005-09-01 Robert Dewar <dewar@adacore.com>
21385 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
21387 * par-prag.adb: Implement new pragma Debug_Policy
21389 * sem_prag.adb Implement new pragma Debug_Policy
21390 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
21391 Component_Size attribute specification. Give warning for ignored pragma
21394 * snames.h, snames.ads, snames.adb: Introduce entries in
21395 Preset_Names for Name_Disp_Asynchronous_Select,
21396 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
21397 Name_Disp_Timed_Select.
21398 New pragma Debug_Policy
21400 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
21402 Switch -gnata also sets Debug_Pragmas_Enabled
21404 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
21405 handle an explicit -gnata when compiling predefined files.
21407 2005-09-01 Vincent Celier <celier@adacore.com>
21409 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
21410 directories of projects that have no Ada sources.
21412 2005-09-01 Robert Dewar <dewar@adacore.com>
21414 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
21415 (makes a difference for wide characters)
21417 * widechar.adb, widechar.ads:
21418 Add Wide_Char_Byte_Count feature to count chars vs bytes
21420 2005-09-01 Thomas Quinot <quinot@adacore.com>
21421 Ed Schonberg <schonberg@adacore.com>
21422 Robert Dewar <dewar@adacore.com>
21424 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
21425 'Address attribute reference with an overloaded prefix, use the
21426 location of the prefix (not the location of the attribute reference) as
21427 the error location.
21428 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
21429 a function renaming thereof, is a valid prefix for 'Size (where it is
21430 intepreted as a function call).
21431 (Statically_Denotes_Entity): New predicate to determine whether the
21432 prefix of an array attribute can be considered static.
21435 (Eval_Attr): Fix failure to evaluate Component_Size for
21436 unconstrained arrays (resulted in wrong value in packed case, since
21437 back end cannot handle this case)
21439 2005-09-01 Robert Dewar <dewar@adacore.com>
21441 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
21442 error msgs for most common cases.
21443 Use new errout insertion char < (conditional warning)
21445 2005-09-01 Javier Miranda <miranda@adacore.com>
21446 Ed Schonberg <schonberg@adacore.com>
21448 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
21449 become local to the whole package.
21450 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
21451 the package was already analyzed the new algorithm "replaces" the
21452 real entities by the shadow ones. This is required to ensure that
21453 the order of these entities in the homonym chains does not change;
21454 otherwise we can have undefined references at linking time because
21455 in case of conflicts the external name of the entities will have
21456 a suffix that depends on the order of the entities in the chain.
21457 (Remove_Limited_With_Clause): Complementary code that completes the
21458 new algorithm and replaces the shadow entities by the real ones.
21459 (Install_Limited_Withed_Unit): When unchaining entities before the
21460 installation of the shadow entities, only regular entities of the
21461 public part must be taken into account. This is required to
21462 keep this routine in synch with the work done by Remove_Limited_
21464 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
21465 even if unit is analyzed, because the analysis of the unit is
21466 idempotent in any case, and the limited view of the unit may have to
21467 be installed for proper visibility.
21468 (Expand_Limited_With_Clause): Even if the unit in the implicit
21469 with_clause has been analyzed already, a limited view of the package
21470 must be built for the current context, if it does not exist yet.
21472 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21473 Javier Miranda <miranda@adacore.com>
21474 Gary Dismukes <dismukes@adacore.com>
21476 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
21477 defining entity for the instance body, make a new defining identifier
21478 rather than copying the entity of the spec, to prevent accidental
21479 sharing of the entity list.
21480 (Check_Private_View): When exchanging views of private types, build the
21481 list of exchanged views as a stack, to ensure that on exit the exchanges
21482 are undone in the proper order.
21483 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
21484 Restore the compilation environment in case of instantiation_error.
21485 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
21486 for an anonymous access result.
21487 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
21488 (Formal_Entity): Handle properly the case of a formal package that
21489 denotes a generic package renaming.
21491 2005-09-01 Thomas Quinot <quinot@adacore.com>
21493 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
21494 clause if the array aggregate is surrounded by parentheses.
21496 2005-09-01 Cyrille Comar <comar@adacore.com>
21497 Gary Dismukes <dismukes@adacore.com>
21498 Ed Schonberg <schonberg@adacore.com>
21499 Javier Miranda <miranda@adacore.com>
21501 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
21503 to check if a type is Constrained in cases related to code generation
21504 (rather than semantic checking) since otherwise we do not generate
21505 similar code for mutable private types depending if their
21506 discriminants are visible or not.
21507 (Check_Abstract_Overriding): Do not complain about failure to override
21508 the primitive operations used in dispatching selects since they will
21509 always be overriden at the freeze point of the type.
21510 (Access_Definition): Separate out handling for resetting the scope
21511 of an anonymous access function result type. Retrieve the scope
21512 of the associated function rather than using Current_Scope, which
21513 does not have a consistent value (depends on whether we're in the
21514 middle of analyzing formal parameters). Add ??? comment about
21515 finding a cleaner way to handle the special cases of scope setting.
21516 (Process_Incomplete_Dependents): A protected operation is never a
21517 dispatching operation (only its wrapper may be).
21518 (Build_Derived_Record_Type): In case of tagged private types that
21519 implement interfaces add derivation of predefined primitive
21521 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
21522 by two parameters that are used in case of derivation from abstract
21523 interface types: No_Predefined_Prims is used to avoid the derivation
21524 of predefined primitives from the interface, and Predefined
21525 Prims_Only is used to complete the derivation predefined primitives
21526 in case of private tagged types implementing interfaces.
21527 Fix typo in comments
21528 (Find_Interface_In_Descendant): Protect the frontend against
21529 wrong code with large circularity chains.
21530 (Is_Private_Overriding): Add support for entities overriding interface
21531 subprograms. The test failed because Entities associated with overriden
21532 interface subprograms are always marked as hidden (and used to build
21533 the secondary dispatch table); in this case the overriden entity is
21534 available through the field abstract_interface_alias (cf. override_
21535 dispatching_operation)
21536 (Access_Definition): Set the scope of the type to Current_Scope for the
21537 case of a function with an anonymous access result type.
21538 (Access_Subprogram_Declaration): Handle creation of the type entity for
21539 an access-to-function type with an anonymous access result.
21540 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
21541 in handling for N_Access_Function_Definition.
21542 (Analyze_Subtype_Declaration): Modify the text of error message.
21543 (Derived_Type_Declaration): Modify the text of error message.
21544 (Process_Subtype): Modify the text of error message plus cleanup
21545 of one redundant error message.
21546 (Analyze_Component_Declaration): Code cleanup.
21547 (Analyze_Object_Declaration): Code cleanup.
21548 (Analyze_Subtype_Declaration): Propagate the null-exclusion
21549 attribute in case of access types. Code cleanup.
21550 (Array_Type_Declaration): Code cleanup.
21551 (Process_Discriminants): Create the new null-excluding itype
21552 if required. Code cleanup.
21553 (Process_Subtype): Create the new null-excluding itype if
21554 required. Code cleanup.
21555 (Build_Derived_Record_Type): Code cleanup to avoid calling
21556 twice the subprogram derive_subprograms in case of private
21557 types that implement interfaces. In this particular case the
21558 subprogram Complete_Subprograms_Derivation already does the
21559 job associated with the second call.
21561 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
21562 conversion to the full view when generating an operation for a
21563 discriminant whose type may currently be private.
21565 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21566 Javier Miranda <miranda@adacore.com>
21568 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
21569 V (Obj.F), the rewriting does not involve the indexed component, but
21570 only the selected component itself.
21571 Do not apply the transformation if the analyzed node is an actual of a
21572 call to another subprogram.
21573 (Complete_Object_Operation): Retain the entity of the
21574 dispatching operation in the selector of the rewritten node. The
21575 entity will be used in the expansion of dispatching selects.
21576 (Analyze_One_Call): Improve location of the error message associated
21578 (Analyze_Selected_Component): No need to resolve prefix when it is a
21579 function call, resolution is done when parent node is resolved, as
21581 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
21582 when attempting to resolve a call transformed from its object notation.
21583 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
21584 of the argument list for each interpretation of the operation.
21585 (Try_Object_Operation): The designated type of an access parameter may
21586 be an incomplete type obtained through a limited_with clause, in which
21587 case the primitive operations of the type are retrieved from its full
21589 (Analyze_Call): If this is an indirect call, and the return type of the
21590 access_to_subprogram is incomplete, use its full view if available.
21592 2005-09-01 Javier Miranda <miranda@adacore.com>
21593 Gary Dismukes <dismukes@adacore.com>
21595 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
21596 access types the null-exclusion and access-to-constant attributes must
21598 (Analyze_Return_Statement): When the result type is an anonymous access
21599 type, apply a conversion of the return expression to the access type
21600 to ensure that appropriate accessibility checks are performed.
21601 (Analyze_Return_Type): For the case of an anonymous access result type,
21602 generate the Itype and set Is_Local_Anonymous_Access on the type.
21603 Add ??? placeholder for check to disallow returning a limited object
21604 in Ada 2005 unless it's an aggregate or a result of a function call.
21605 Change calls from Subtype_Mark to Result_Definition.
21606 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
21607 Result_Definition in call to Make_Function_Specification.
21608 (Build_Body_To_Inline): Change Set_Subtype_Mark to
21609 Set_Result_Definition.
21610 (Make_Inequality_Operator): Change formal Subtype_Mark to
21611 Result_Definition in call to Make_Function_Specification.
21612 (Process_Formals): Create the new null-excluding itype if required.
21613 (New_Overloaded_Entity): For an entity overriding an interface primitive
21614 check if the entity also covers other abstract subprograms in the same
21615 scope. This is required to handle the general case, that is, overriding
21616 other interface primitives and overriding abstract subprograms inherited
21617 from some abstract ancestor type.
21618 (New_Overloaded_Entity): For an overriding entity that comes from
21619 source, note the operation that it overrides.
21620 (Check_Conformance, Type_Conformant): Addition of one new formal
21621 to skip controlling formals in the analysis. This is used to
21622 handle overloading of abstract interfaces.
21623 (Base_Types_Match): Add missing case for types imported from
21624 limited-with clauses
21625 (New_Overloaded_Entity): Add barrier to protect the use of
21626 the "alias" attribute.
21628 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21630 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
21631 verify that the procedure and the entry are mode conformant.
21632 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
21633 as a different operator, which is often a cut-and-paste error.
21635 2005-09-01 Javier Miranda <miranda@adacore.com>
21636 Ed Schonberg <schonberg@adacore.com>
21638 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
21639 used in controlling parameters exclude null because it is necessary to
21640 read the tag to dispatch, and null has no tag.
21641 (Override_Dispatching_Operation): If the previous operation is inherited
21642 from an interface, it becomes hidden and does not participate in later
21645 2005-09-01 Javier Miranda <miranda@adacore.com>
21646 Ed Schonberg <schonberg@adacore.com>
21647 Gary Dismukes <dismukes@adacore.com>
21649 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
21650 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
21651 the expander will generate the corresponding run-time check to evaluate
21653 (Resolve_Call): Check for legal type of procedure name or prefix that
21654 appears as a trigger in a triggering alternative.
21655 (Valid_Conversion): If expression is ambiguous and the context involves
21656 an extension of System, remove System.Address interpretations.
21657 (Resolve_Qualified_Expression): Reject the case of a specific-type
21658 qualification applied to a class-wide argument. Enhance comment
21659 to explain checking of Original_Node.
21660 (Resolve_Type_Conversion): The location of the error message was not
21661 general enough to handle the general case and hence it has been removed.
21662 In addition, this patch improves the text of the message.
21663 (Resolve_Type_Conversion): Add missing support for access to interface
21665 (Resolve_Type_Conversion): If the target is a class-wide interface type,
21666 do not expand if the expression is the actual in a call, because proper
21667 expansion will take place when the call itself is expanded.
21668 (Resolve_Allocator): If the context is an unchecked conversion, the
21669 allocator inherits its storage pool, if any, from the target type of
21672 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21673 Javier Miranda <miranda@adacore.com>
21675 * sem_type.adb (Add_One_Interp): If a candidate operation is an
21676 inherited interface operation that has an implementation, use the
21677 implementation to avoid spurious ambiguities.
21678 (Interface_Present_In_Ancestor): In case of concurrent types we can't
21679 use the Corresponding_Record_Typ attribute to look for the interface
21680 because it is set by the expander (and hence it is not always
21681 available). For this reason we traverse the list of interfaces
21682 (available in the parent of the concurrent type).
21683 (Interface_Present_In_Ancestor): Handle entities from the limited view
21685 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21687 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
21688 from the list of required components.
21689 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
21690 primitive procedure of a limited interface with a controlling first
21692 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
21694 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
21695 capture if it is generated in the second operand of a short-circuit
21697 Do not capture values for variables with address clauses.
21698 (Is_Object_Reference): Treat a function call as an object reference only
21699 if its type is not Standard_Void_Type.
21701 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21703 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
21704 to a variable that is statically known to be constant.

21721 Document new treatment of wide characters in max line length
21723 Remove -gnatL/-gnatZ switches, no longer used.
21724 Add note on pragmas Assertion_Policy and Debug_Policy in discussion

21963 _withed_unit that checks if some package installed through normal with
21964 clauses has a renaming declaration of package whose limited-view is

21966 of the current Draft document for Ada 2005.
21967 (Analyze_Context): Complete the list of compilation units that
21968 are allowed to contain limited-with clauses. It also contains

22486 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
22487 longer protected objects. They have been replaced by lower-level
22488 suspension objects made up by a mutex and a condition variable (or
22489 their equivalent given a particular OS) plus some internal data to
22490 reflect the state of the suspension object.
22491 (Initialize, Finalize): Add this initialization procedure for
22492 Suspension_Object, which is a controlled type.
22493 (Finalize): Add the finalization procedure for Suspension_Object,
22494 which is a controlled type.
22496 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

22514 (Current_State): Add this function that returns the state of the
22516 (Set_False): Add this procedure that sets the state of the suspension
22518 (Set_True): Add this procedure that sets the state of the suspension
22519 object to True, releasing the task that was suspended, if any.
22520 (Suspend_Until_True): Add this procedure that blocks the calling task
22521 until the state of the object is True. Program_Error is raised if
22522 another task is already waiting on that suspension object.
22523 (Initialize): Add this procedure for initializing the suspension
22524 object. It initializes the mutex and the condition variable which are
22525 used for synchronization and queuing, and it sets the internal state
22527 (Finalize): Add this procedure for finalizing the suspension object,
22528 destroying the mutex and the condition variable.

22533 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
22534 which provides a low-level abstraction (using operating system
22535 primitives) for Ada.Synchronous_Task_Control.
22536 This object is made up by a mutex (for ensuring mutual exclusion), a
22537 condition variable (for queuing threads until the condition is
22538 signaled), a Boolean (State) indicating whether the object is open,
22539 and a Boolean (Waiting) reflecting whether there is a task already
22540 suspended on this object.

22716 and raise Tag_Error if the passed tag equalis No_Tag, to conform with
22717 Ada 2005 semantics for the new predefined function.
22719 * exp_attr.adb (Expand_N_Attribute, case Attribute_Input): Generate
22720 call to Descendant_Tag rather than Internal_Tag.
22721 (Expand_N_Attribute, case Attribute_Output): Emit a check to ensure that
22722 the accessibility level of the attribute's Item parameter is not deeper
22723 than the level of the attribute's prefix type. Tag_Error is raised if

22731 is a dereference of an object with a constrained partial view.
22733 * exp_ch5.adb (Expand_N_Return_Statement): When a function's result
22734 type is a class-wide type, emit a run-time check that the accessibility

22741 (Make_DT): Generate a call to set the accessibility level of the
22742 tagged type in its TSD.
22743 (Make_DT): Code cleanup. The functionality of generating all the
22744 secondary dispatch tables has been moved to freeze_record_type.
22745 (Make_Abstract_Interface_DT): Minor code cleanup.

22747 this subprogram implements a new algorithm that provides the
22748 same functionality and it is more clear in case of primitives
22749 associated with abstract interfaces.
22750 (Set_All_Interfaces_DTC_Entity): Removed. As part of the code
22751 clean up, the functionality of this subprogram is now provided
22752 by Set_All_DT_Position.

22754 within gdb to display the dispatch tables associated with a tagged
22756 (Collect_All_Interfaces): New subprogram that collects the whole list
22757 of interfaces that are directly or indirectly implemented by a tagged
22759 (Default_Prim_Op_Position): New subprogram that returns the fixed
22760 position in the dispatch table of the default primitive operations.
22761 (Expand_Interface_Actuals): New subprogram to generate code that
22762 displaces all the actuals corresponding to class-wide interfaces to
22763 reference the interface tag of the actual object.

22982 way as a normal component of an anonymous access type.
22983 (Resolve_Allocator): When an allocator's designated type is a class-wide
22984 type, check that the accessibility level of type given in the

23964 (check dos line terminator).
23965 (Check_Line_Max_Length): New procedure, split off from the existing
23966 Check_Line_Terminator routine. Separating this out allows -gnatyf to
23967 be properly recognized.
23969 * styleg.adb: Add ??? comment for line terminator reference

24012 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
24013 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
24014 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
24015 analyzed if expansion is disabled (which could otherwise cause spurious
24016 error messages if expansion has been disabled due to previous
24017 (unrelated) errors).
24019 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
24020 is disabled, the entity denoted by the argument is the access type
24021 itself, not an underlying record type, so there is no need to go back
24022 to the Corresponding_Remote_Type.
24024 2005-03-29 Gary Dismukes <dismukes@adacore.com>
24025 Robert Dewar <dewar@adacore.com>
24027 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
24028 expand a call to an instance of
24029 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
24030 Constructor actual of the instance. A class-wide membership
24031 check is also generated, to ensure that the tag passed to the instance
24032 denotes a type in the class.
24033 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
24034 of Name_Generic_Dispatching_Constructor.
24036 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
24037 05 unit for AI-260-02).
24039 * a-tgdico.ads: New file.

24049 character type cases.
24050 (Analyze_Subprogram_Renaming): Add special handling for
24051 the case of renaming of stream attributes when the renaming denotes a
24052 generic formal subprogram association for an abstract formal subprogram.
24053 Check that the attribute is a primitive stream attribute (and not
24054 a class-wide stream attribute) and then rewrite the attribute name
24055 as the name of the appropriate compiler-generated stream primitive.
24057 2005-03-29 Robert Dewar <dewar@adacore.com>
24059 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to
24061 (Is_Possibly_Unaligned_Object): Correct typo that
24062 resulted in inaccurate result for unaligned scalars within records.
24064 2005-03-29 Ed Schonberg <schonberg@adacore.com>
24066 * freeze.adb (Freeze_Record_Type): If the type of the component is an
24067 itype whose parent is controlled and not yet frozen, do not create a
24068 freeze node for the itype if expansion is disabled.
24070 2005-03-29 Vincent Celier <celier@adacore.com>
24072 * make.adb (Gnatmake): Don't fail if the main project file is declared
24073 as having no Ada sources. Do not display message "no sources to
24074 compile" in quiet output.
24076 2005-03-29 Doug Rupp <rupp@adacore.com>
24078 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

24083 * par-ch12.adb (P_Generic): Give better msg for illegal private generic
24086 2005-03-29 Robert Dewar <dewar@adacore.com>
24088 * par-ch3.adb (P_Type_Declaration): Fix bad error recovery after
24089 missing TYPE Improve the error message generated when compiling a
24090 limited interface in Ada83 or Ada95 mode.
24092 2005-03-29 Robert Dewar <dewar@adacore.com>
24094 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
24095 rather than proceed ahead using a junk attribute name.
24097 2005-03-29 Vincent Celier <celier@adacore.com>
24099 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
24101 * prj-part.adb (Parse_Single_Project): Set the location of a project
24102 on its defining identifier, rather than on the reserved word "project".
24104 * prj-proc.adb (Expression): Adapt to the fact that default of external
24105 references may be string expressions, not always literal strings.
24106 (Recursive_Process): Set Display_Name equal to Name
24107 when Location is No_Location, that is when there is no actual file.
24108 Get the Display_Name of the project from the source, when it is not a
24110 (Process): Use the Display_Name in error messages
24112 * prj-strt.adb (External_Reference): Allow default to be string
24113 expressions, not only literal strings.
24115 2005-03-29 Vincent Celier <celier@adacore.com>
24117 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
24118 file and the reference symbol file to be the same file.
24120 2005-03-29 Thomas Quinot <quinot@adacore.com>
24122 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
24123 forbid conversion of a local access-to-subprogram type to a remote one.
24125 * sem_util.adb (Wrong_Type): For a record type that is the expanded
24126 equivalent type for a remote access-to-subprogram type, go back to the
24127 original RAS entity when displaying an error message, so the casing is
24128 the original source casing.
24130 2005-03-29 Robert Dewar <dewar@adacore.com>
24132 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
24135 2005-03-29 Ed Schonberg <schonberg@adacore.com>
24137 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
24138 subtype if code is being pre-analyzed, to prevent un-expanded
24139 references to protected formals, among others.
24140 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
24141 interpretation that can be a call, include the result of the call as a
24142 possible interpretation of the dereference.
24144 * sem_ch5.adb (Process_Bounds): Determine type of range by
24145 pre-analyzing a copy of the original range, and then analyze the range
24146 with the expected type.
24148 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
24149 with an overloaded prefix where not all interpretations yield an
24150 access to subprogram, do not rewrite node as a call.
24151 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
24152 the node as a call once the context identifies the interpretation of
24153 the prefix whose call yields the context type.
24154 (Valid_Conversion): For the case of a conversion between
24155 local access-to-subprogram types, check subtype conformance using
24156 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
24157 detailed error message.
24159 2005-03-29 Ed Schonberg <schonberg@adacore.com>
24161 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
24162 indicator, indicate that the formal can never be null.
24163 (Process_Formals): If a formal has a non_null indicator, insert the
24164 resulting subtype immediately before the enclosing subprogram decl,
24165 and not at the beginning of the corresponding declarative part, to
24166 prevent access before elaboration (Ada2005).
24168 2005-03-29 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24171 * utils.c (finish_record_type): Use variable_size when setting sizes.
24173 2005-03-29 Robert Dewar <dewar@adacore.com>
24175 * xtreeprs.adb, xnmake.adb: Use Stream_IO instead of Text_IO to
24176 guarantee Unix style line terminators for the output files, even when
24177 running on windows.

24653 Project_Node_Tree_Ref to most subprograms.
24654 Use this new parameter to store project nodes in the designated project
24656 (Project_Node_Tree_Ref): New type to designate a project node tree
24657 (Tree_Private_Part): Change table to dynamic table and hash tables to
24658 dynamic hash tables.
24660 * prj-util.ads, prj-util.adb: Add new parameter In_Tree to designate
24661 the project tree to most subprograms. Adapt to changes in project
24662 manager using project tree In_Tree.

24667 2005-03-15 Olivier Hainque <hainque@adacore.com>
24669 * s-intman-posix.adb (Notify_Exception): Adjust signature, as handler
24670 for sigactions with SA_SIGINFO set. Call
24671 __gnat_adjust_context_for_raise before raising, to perform the
24672 potentially required adjustments to the machine context for the GCC
24675 * raise.h (__gnat_adjust_context_for_raise): New prototype.
24677 * init.c (__gnat_adjust_context_for_raise) HPUX: Initial revision.
24678 Adjust PC by one in the provided machine context.
24679 (__gnat_install_handler) HPUX: Set SA_SIGINFO in the sigaction flags,
24680 so that the handler is passed the context structure to adjust prior to
24682 (__gnat_error_handler) HPUX: Adjust the signature to match what an
24683 SA_SIGINFO sigaction should look like. Call
24684 __gnat_adjust_context_for_raise before actually raising.
24685 (__gnat_adjust_context_for_raise): Default noop to help PC
24686 adjustments before raise from signal handlers.
24687 (__gnat_error_handler): Indirectly call a predicate function to
24688 determine if a condition should be resignaled or not.
24689 (__gnat_set_resignal_predicate): User interface to modify the predicate.

24717 a-stwiun.ads, a-stwiun.adb, a-strunb.ads, a-strunb.adb: Move
24718 Realloc_For_Chunk to private part of package.
24719 New subprograms for AI-301
24721 * a-szuzti.adb, a-suteio.adb, a-swuwti.adb: Improve efficiency of
24722 Get_Line procedure.
24723 Avoid unnecessary use of Get/Set_Wide_String
24725 2005-03-15 Robert Dewar <dewar@adacore.com>
24728 * a-stunau.ads, a-stunau.adb:
24729 Change interface to allow efficient (and correct) implementation
24730 The previous changes to allow extra space in unbounded strings had
24731 left this interface a bit broken.
24733 * a-suteio.adb: Avoid unnecessary use of Get/Set_String
24735 * g-spipat.ads, g-spipat.adb: New interface for Get_String
24736 Minor reformatting (function specs)

24746 2005-03-15 Javier Miranda <miranda@adacore.com>
24747 Robert Dewar <dewar@adacore.com>
24748 Thomas Quinot <quinot@adacore.com>
24749 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24751 * atree.ads, atree.adb: Add support for Elist24 field
24753 * atree.h: Fix wrong definition of Field27
24754 Add support for Elist16 field
24755 Add support for Elist24 field
24757 * einfo.ads, einfo.adb (Abstract_Interfaces,
24758 Set_Abstract_Interfaces): New subprograms.

24770 (Set_Task_Body_Procedure): New subprogram to set this attribute.
24771 (Has_Controlled_Component): Now applies to all entities.
24772 This is only a documentation change, since it always worked to apply
24773 this to other than composite types (yielding false), but now this is
24775 Update documentation on Must_Be_Byte_Aligned for new spec
24777 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
24778 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
24779 uses of the Access_Disp_Table attribute to reference the first dispatch
24780 table associated with a tagged type. As
24781 part of the implementation of abstract interface types,
24782 Access_Disp_Table has been redefined to contain a list of dispatch
24783 tables (rather than a single dispatch table).
24784 Similarly, upgrade all the references to Tag_Component by the
24785 new attribute First_Tag_Component.
24786 (Find_Inherited_TSS): Moved to exp_tss.
24787 Clean up test in Expand_N_Object_Declaration for cases
24788 where we need to do a separate assignment of the initial value.
24789 (Expand_N_Object_Declaration): If the expression in the
24790 declaration of a tagged type is an aggregate, no need to generate an
24791 additional tag assignment.
24792 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
24794 Bit packed array ops are only called if operands are known to be
24796 (Component_Equality): When returning an N_Raise_Program_Error statement,
24797 ensure that its Etype is set to Empty to avoid confusing GIGI (which
24798 expects that only expressions have a bona fide type).
24799 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
24800 determine the amount of data to be copied.
24802 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
24803 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
24804 INTERFACE_TYPE_DEFINITION ::=
24805 [limited | task | protected | synchronized] interface
24806 [AND interface_list]
24808 * par-ch3.adb (P_Type_Declaration): Modified to give support to
24810 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to

24813 syntax rule of Ada 2005 interfaces
24814 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
24815 messages by the correct RENAMES (quotes removed).
24817 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
24818 attribute First_Tag_Component.
24820 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
24821 (Interface_List, Set_Interface_List): New subprograms.
24822 (Interface_Present, Set_Interface_Present): New subprograms.

24824 type definition nodes.
24825 (Protected_Present, Set_Protected_Present): Available also in
24826 record type definition and
24827 derived type definition nodes.
24828 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
24829 (Task_Present, Set_Task_Present): New subprogram.
24830 (Task_Body_Procedure): Removed.
24831 (Set_Task_Body_Procedure): Removed.
24832 These subprogram have been removed because the attribute
24833 Task_Body_Procedure has been moved to the corresponding task type
24834 or task subtype entity to leave a field free to store the list
24835 of interfaces implemented by a task (for AI-345)
24836 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
24837 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
24838 expression flag Do_Range_Check
24839 (Exception_Junk): Change to Flag7 to accomodate above change
24840 (Box_Present, Default_Name, Specification, Set_Box_Present,
24841 Set_Default_Name, Set_Specification): Expand the expression
24842 "X in N_Formal_Subprogram_Declaration" into the corresponding
24843 two comparisons. Required to use the csinfo tool.

24846 "with string" given.
24848 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
24851 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
24854 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
24855 attribute Task_Body_Procedure rather than the old semantic field that
24856 was available in the task_type_declaration node.
24858 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
24859 interface type definitions.
24860 (P_Formal_Derived_Type_Definition): Modified to handle the list of
24863 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
24864 task type declaration.
24865 (P_Protected): Modified to handle the list of interfaces in a
24866 protected type declaration.
24868 2005-03-15 Doug Rupp <rupp@adacore.com>
24869 Vincent Celier <celier@adacore.com>
24871 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
24872 (Gen_Output_File_C): Likewise.
24873 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
24875 2005-03-15 Thomas Quinot <quinot@adacore.com>
24877 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
24878 is an N_Raise_Constraint_Error node, create a new copy of it without
24879 going through a call to Duplicate_Subexpr.
24881 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
24882 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24883 Nicolas Setton <setton@adacore.com>
24884 Ed Schonberg <schonberg@adacore.com>
24890 * decl.c (gnat_to_gnu_field): Reject aliased components with a
24891 representation clause that prescribes a size not equal to the rounded
24892 size of their types.
24893 (gnat_to_gnu_entity, case E_Component): Always look at
24894 Original_Record_Component if Present and not the entity.
24895 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
24896 of tagged extension types by not making field for components that are
24898 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
24899 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
24900 expression to the type of the object when the object is constant.
24901 Reverse defer_debug_incomplete_list before traversing it, so that trees
24902 are processed in the order at which they were added to the list. This
24903 order is important when using the stabs debug format.
24904 If we are deferring the output of debug information, also defer this
24905 output for a function return type.
24906 When adding fields to a record, prevent emitting debug information
24907 for incomplete records, emit the information only when the record is
24909 (components_to_record): New parameter defer_debug.
24910 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
24911 (gnat_to_gnu_field_decl): New function.
24912 (substitution_list, annotate_rep): Call it.
24913 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
24914 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
24915 No longer update discriminants to not be a COMPONENT_REF.
24916 (copy_alias_set): Strip padding from input type; also handle
24917 unconstrained arrays properly.
24919 * gigi.h (write_record_type_debug_info): New function.
24920 Convert to use ANSI-style prototypes. Remove unused
24921 declarations for emit_stack_check, elab_all_gnat and
24922 set_second_error_entity.
24923 (gnat_to_gnu_field_decl): New decl.
24925 * utils.c (write_record_type_debug_info): New function.
24926 (finish_record_type): Delegate generation of debug information to

24929 (update_pointer_to): Fix pasto.
24930 (convert) <UNION_TYPE>: Accept slight type variations when
24931 converting to an unchecked union type.
24933 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
24934 replace the N_Freeze_Entity with a null statement.
24936 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
24937 within a constrained subcomponent of an enclosing record, place the
24938 freeze nodes in the scope stack entry for the enclosing record.
24939 (Undelay_Type): New Subprogram.
24940 (Set_Small_Size): Pass T, the type to modify; all callers changed.
24941 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
24942 within records; allow them to have freeze nodes if their base types
24945 * exp_util.adb (Remove_Side_Effects): Properly test for
24946 Expansion_Delayed and handle case when it's inside an
24947 N_Qualified_Expression.
24949 * sem_ch3.adb (Derived_Type_Declaration): New predicate
24950 Comes_From_Generic, to recognize accurately that the parent type in a
24951 derived type declaration can be traced back to a formal type, because
24952 it is one or is derived from one, or because its completion is derived
24954 (Constrain_Component_Type): If component comes from source and has no
24955 explicit constraint, no need to constrain in in a subtype of the
24957 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
24958 Minor change to propagate Is_Ada_2005 flag
24960 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
24961 Expansion_Delayed is False.
24962 (assoc_to_constructor): Ignore fields that have a
24963 Corresponding_Discriminant.
24964 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
24965 function returns "by target", dereference the target pointer using the
24966 type of the actual return value.
24967 <all>: Be prepared for a null gnu_result.
24968 (processed_inline_subprograms): Check flag_really_no_inline
24969 instead of flag_no_inline.
24970 (set_second_error_entity): Remove unused function.

24975 2005-03-15 Robert Dewar <dewar@adacore.com>
24976 Ed Schonberg <schonberg@adacore.com>
24977 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24979 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
24980 Must_Be_Byte_Aligned for cases where we do not need to use a
24981 System.Pack_nn unit.
24983 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
24985 Needed now that we do some processing for IN parameters as well. This
24986 may well fix some unrelated errors.
24987 (Expand_Call): Handle case of unaligned objects (in particular those
24988 that come from packed arrays).
24989 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
24990 renamed entity is an inherited operation, re-expand the call using the
24991 original operation, which is the one to call.
24992 Detect attempt to inline parameterless recursive subprogram.
24993 (Represented_As_Scalar): Fix to work properly with private types
24994 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
24995 accurate estimate. Yields True in far fewer cases than before,
24996 improving the quality of code that depends on this test.
24998 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
24999 over both visible and private declarations to remove them from tree,
25000 and mark subprograms declared in package as eliminated, to prevent
25001 spurious use in subsequent compilation of generic units in the context.
25003 * exp_util.ads: Minor cleanup in variable names
25005 * sem_eval.ads, sem_eval.adb: Minor reformatting
25006 (Compile_Time_Known_Bounds): New function
25008 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25010 * exp_ch7.adb (Convert_View): Use base types of underlying types when
25011 determining whether an unchecked conversion is needed for the argument
25012 of an initialization call.
25014 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25016 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
25017 that appears in the instantiation rather than the internal subtype
25018 generated in the wrapper package, to avoid anomalies in gigi when the
25019 target is derived from a private type whose full view is an access type.
25021 2005-03-15 Robert Dewar <dewar@adacore.com>
25023 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
25025 Add documentation to replace the use of this flag
25026 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
25029 2005-03-15 Thomas Quinot <quinot@adacore.com>
25031 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
25032 here from exp_attr so it can be shared between exp_attr and exp_dist.
25033 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
25034 all TSS names, not a subset thereof, and the previous name introduced
25035 an unnecessarily confusion that a distinction might exist between
25036 "OK" TSS names and some "not OK" TSS names.
25038 2005-03-15 Doug Rupp <rupp@adacore.com>
25040 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
25043 2005-03-15 Pascal Obry <obry@adacore.com>
25044 Eric Botcazou <ebotcazou@adacore.com>
25048 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
25049 when IN_RTS. This is to work around a bootstrap path problem.
25051 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
25052 table and pass it to __gnat_install_SEH_handler().
25053 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
25055 * lang.opt: Fix specification of -fRTS=.
25057 2005-03-15 Doug Rupp <rupp@adacore.com>
25058 Bernard Banner <banner@adacore.com>
25059 Vincent Celier <celier@adacore.com>
25060 Arnaud Charlet <charlet@adacore.com>
25063 This change works fine when gnatlib is built from the gcc directory,
25064 but does not work when using the libada Makefile, since GCC_FOR_TARGET
25065 is not passed to ada/Makefile.in, so more work is needed by a
25066 Makefile/configure expert.
25068 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
25069 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
25070 Setup gnatlink switch -M for x86_64 linux, as it is already setup
25072 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
25073 Run ranlib on libgccprefix.a
25074 Define PREFIX_OBJS for Darwin, to build libgccprefix.
25075 (ADA_INCLUDE_SRCS): Split Ada packages.
25077 2005-03-15 Robert Dewar <dewar@adacore.com>
25079 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
25081 * impunit.adb: Add GNAT.UTF_32
25083 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
25085 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
25086 now uses GNAT.UTF_32).
25088 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
25089 capabilities for categorizing characters using Unicode categories
25091 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25093 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
25094 instantiation that has been rewritten as a package body, retrieve spec
25095 to generate proper name for implicit_with_clause.
25096 (Install_Parents): Recognize a parent that is an instantiation but has
25097 been rewritten as a package declaration during analysis.
25099 2005-03-15 Javier Miranda <miranda@adacore.com>
25100 Ed Schonberg <schonberg@adacore.com>
25102 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
25103 parameter reported some error we immediately return. This improves the
25104 behaviour of the frontend in case of errors.
25105 (Install_Parent, Remove_Parent): Introduce new flag
25106 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
25107 ancestor of a generic child unit, when the child is being instantiated.
25108 (Inline_Instance_Body): If we are compiling the private
25109 part or the body of a child unit, restore the proper visibility of the
25110 parents after compiling the instance body.
25112 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25113 Javier Miranda <miranda@adacore.com>
25116 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
25117 of a private type, in which case it is underlying_type that denotes
25118 the proper task. Also modified to use the new entity attribute
25119 that is directly available in the task type and task subtype entities
25120 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
25121 arrays when other dimensions than the first are constrained by
25122 discriminants of an enclosing record.
25123 (Insert_Explicit_Dereference): If the prefix is an indexed component or
25124 a combination of indexed and selected components, find ultimate entity
25125 and generate the appropriate reference for it, to suppress spurious
25127 (Note_Possible_Modification): If an entity name has no entity, return.
25128 (Is_Variable): A function call never denotes a variable.
25129 (Requires_Transient_Scope): For record types, recurse only on
25130 components, not on internal subtypes that may have been generated for
25131 constrained components.
25133 2005-03-15 Ed Schonberg <schonberg@adacore.com>

25618 directly a value of type Ada.Tag rather than a tagged object.
25620 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
25621 describing the new layout.
25622 (Dispatch_Table): The expander computes the actual array size, allocates
25623 the Dispatch_Table record accordingly, and generates code that displaces
25624 the base of the record after the Typeinfo_Ptr component. The access to
25625 these components is done by means of local functions.
25626 (Offset_To_Top): New function.
25627 (Typeinfo_Ptr): New function.
25628 (Get_TSD): Modified to access the new position of the TSD.
25629 (Set_TSD): Modified to save the TSD in its new position.
25631 * par-ch12.adb (P_Formal_Subprogram_Declaration): Add parsing for the
25632 case of formal abstract subprograms. Add check and message for -gnat05.
25635 * sem_ch12.adb: Add with and use for Sem_Disp.
25636 (Analyze_Associations): Minor change from "=" to "in" for use of
25637 N_Formal_Subtype_Declaration (which is now a subtype).
25638 (Set_Analyzed_Formal): Minor changes from "=" to "in" for uses of
25639 N_Formal_Subtype_Declaration (which is now a subtype).
25640 (Analyze_Formal_Subprogram): Add handling for
25641 N_Formal_Abstract_Subprogram, marking the formal as abstract and
25642 dispatching, setting the controlling status of the formal parameters
25643 and result, and issuing an error if there is no controlling type for
25644 the formal subprogram.
25645 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
25646 which is an unclean use of that field, we set the new field
25647 Corresponding_Formal_Spec to make the formal subprogram available to
25648 processing in Analyze_Subprogram_Declaration.
25649 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
25650 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
25651 Constrained, so that it is is does not statically match its anonymous
25654 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
25655 abstract formal subprograms in error check for functions returning
25656 abstract types. Set scope of new designator for
25657 a parameterless subprogram, so that it is available when checking the
25658 body for nested subprograms, before full analysis of said body.
25659 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
25660 subprogram only if inner one comes from source.
25661 (Analyze_Function_Call): If the call is given in object notation, the
25662 analysis of the name rewrites the node and analyzes it with the proper
25663 argument list. After analyzing the name, if the call has been rewritten
25664 and the result type is set, no further analysis is needed.
25665 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
25666 mark in function specification, in a context where the formals are
25667 visible and hide outer homographs.
25669 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
25670 as the tagged type for the cases of abstract formal subprograms and
25671 renamings of those. Clean up spec comments.
25672 (Check_Dispatching_Context): Add error message to indicate "abstract
25673 procedure", covering the case of a call to a formal abstract procedure
25674 that has statically tagged operands.
25675 (Check_Dispatching_Call): Check for the case of an actual given by
25676 a tag-indeterminate function call whose type is an ancestor of the
25677 containing call's associated tagged type. This situation can occur
25678 for inherited primitives with function defaults. In this case we
25679 use the tagged type's tag directly as the controlling argument for
25681 (Expand_Call): Name change on call to Expand_Dispatch_Call.
25683 * sprint.adb (Sprint_Node_Actual): Split
25684 N_Formal_Subprogram_Declaration into two alternatives for the new
25685 cases N_Formal_Abstract_Subprogram_Declaration and
25686 N_Formal_Concrete_Subprogram_Declaration.
25687 Char_Literal_Value field is now a Uint.
25689 * trans.c: Get rid of junk Uint2 reference.
25690 Char_Literal_Value field is now a Uint.
25691 (gnat_to_gnu, case N_Aggregate): Check TYPE_UNCHECKED_UNION_P.
25692 (gigi): Correct third arg to gimplify_body.
25694 * ada-tree.h: (TYPE_UNCHECKED_UNION_P): New flag.
25695 (TYPE_LANG_FLAG_0): Check for record or union.
25697 * treepr.adb: Char_Literal_Value field is now a Uint
25699 * uintp.h, uintp.ads, uintp.adb: Add new routines UI_To_CC and
25702 * widechar.ads, widechar.adb (Is_UTF_32_Non_Graphic): New function
25703 Add full UTF-32 support
25704 Char_Code is now 32 bits
25706 * sinput.ads, sinput.adb (Skip_Line_Terminators): Extend to deal with
25707 wide character UTF_32 line terminators.
25708 Initialize Main_Source_File to avoid error when no main
25711 * errout.adb (Finalize): Do not check Num_SRef_Pragmas
25712 (Main_Source_File) when no main source has been loaded, to avoid
25715 2005-02-09 Robert Dewar <dewar@adacore.com>
25717 * a-strunb.ads, a-strunb.adb: Add missing pragma Ada_05 statements

25724 a-strsea.ads, a-strsea.adb: Add new index functions from AI-301 to
25727 * a-witeio.ads, a-witeio.adb, a-textio.ads, a-textio.adb: New function
25728 forms of Get_Line subprograms for AI-301.
25730 * a-wtcoau.adb, a-wtcoau.ads, a-wtcoio.adb, a-wtcoio.ads,
25731 a-wtedit.adb, a-wtedit.adb, a-wtedit.ads, a-wttest.adb,
25732 a-wttest.ads, a-strmap.ads, a-strmap.adb, a-stwima.adb,
25733 a-stwima.ads: Minor reformatting.
25735 2005-02-09 Doug Rupp <rupp@adacore.com>
25736 Thomas Quinot <quinot@adacore.com>
25738 * adaint.c, adaint.h
25739 [VMS] (to_ptr32): New function.
25740 (MAYBE_TO_PTR32): New macro.
25741 (__gnat_portable_spawn,__gnat_portable_no_block_spawn): Adjust argv
25743 [VMS] (descriptor_s, ile_s): Use __char_ptr32 for adr field.
25744 [VMS] (#define fork()): Remove since unneccessary.
25745 (__gnat_set_close_on_exec): New routine to support
25746 GNAT.OS_Lib.Set_Close_On_Exec.
25748 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
25749 the parent side as close-on-exec so that they are not inherited by the
25752 * g-os_lib.ads, g-os_lib.adb (Set_Close_On_Exec): New subprogram to
25753 set or clear the FD_CLOEXEC flag on a file descriptor.
25755 2005-02-09 Eric Botcazou <ebotcazou@adacore.com>
25756 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
25760 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
25761 on the field if Pragma Component_Alignment (Storage_Unit).
25762 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
25763 side-effects as if it were a constant; also make SAVE_EXPR to protect
25765 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
25767 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
25768 (components_to_record): Test it.
25769 Fix improper usage of REFERENCE_CLASS_P.
25771 * utils2.c (build_binary_op, case MODIFY_EXPRP): Treat UNION_TYPE as
25774 * utils2.c: Minor reformatting.
25776 * utils.c (convert, case UNION_TYPE): Check TYPE_UNCHECKED_UNION;
25777 handle other cases like RECORD_TYPE.
25779 * utils.c (gnat_pushdecl): Set TREE_NO_WARNING.
25781 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25783 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
25784 component of an array of arrays in an assignment context, and the
25785 aggregate has component associations that require sliding on
25786 assignment, force reanalysis of the aggregate to generate a temporary
25787 before the assignment.
25788 (Must_Slide): Make global to the package, for use in Gen_Assign.
25790 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25792 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
25793 unchecked union with no inferable discriminants, return a
25794 Raise_Program_Error node, rather than inserting it at the point the
25796 (Expand_Record_Equality, Component_Equality): Handle properly the case
25797 where some subcomponent is an unchecked union whose generated equality
25798 code raises program error.
25800 2005-02-09 Doug Rupp <rupp@adacore.com>
25802 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.

25805 2005-02-09 Pascal Obry <obry@adacore.com>
25806 Arnaud Charlet <charlet@adacore.com>
25808 * init.c (__gnat_initialize): Add a new parameter eh which contains the
25809 address of the exception registration. The Win32 version of this
25810 routine calls __gnat_install_SEH_handler() to initialize the SEH
25811 (Structured Exception Handling) handler.
25812 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
25813 SEH (Structured Exception Handling) now.
25814 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
25815 (__gnat_initialize for ppc-vxworks): Adjust comments and the
25816 preprocessor condition protecting the call to the extra eh setup
25817 subprogram, which is only available for the ppc target.
25818 (__gnat_clear_exception_count): replaced reference to
25819 variable taskIdCurrent by call to taskIdSelf(), cleaner.
25821 * seh_init.c: New file.
25823 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
25824 (GNATBIND_OBJS): Idem.
25826 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
25827 routine takes a new parameter (a pointer to the exception registration
25828 for the SEH (Structured Exception Handling) support.
25830 * raise.h: (__gnat_install_SEH_handler): New prototype.
25831 Update copyright notice.
25833 * s-tassta.adb (Task_Wrapper): Declare the exception registration
25834 record and initialize it by calling __gnat_install_SEH_handler.
25836 2005-02-09 Vincent Celier <celier@adacore.com>
25838 * make.adb (Gnatmake): Do not fail when the main project has no object
25841 2005-02-09 Doug Rupp <rupp@adacore.com>
25843 * Makefile.in [VMS] (LN,LN_S): Define as cp -p
25844 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
25845 [VMS]: Add translations for g-enblsp.adb.
25847 * s-asthan-vms.adb: Removed.
25848 * s-asthan-vms-alpha.adb: Added.
25850 2005-02-09 Pascal Obry <obry@adacore.com>
25852 * Makefile.in (LIBGNAT_SRCS): Add seh_init.c.
25853 (LIBGNAT_OBJS): Add seh_init.o.
25855 2005-02-09 Arnaud Charlet <charlet@adacore.com>
25858 * Makefile.in: Link all gnat tools with -static-libgcc, since
25859 -shared-libgcc is now used by default on some systems (e.g. linux with
25861 Remove references to Makefile.prolog/generic, no longer used.
25863 2005-02-09 Vincent Celier <celier@adacore.com>
25865 * prj-makr.adb (Process_Directory): Put file name in canonical case
25866 before matching against the patterns.
25867 If gnatname has been invoked as <prefix>-gnatname
25868 then invoke the compiler as <prefix>-gcc, not just "gcc".
25870 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25872 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
25873 with expansion disabled. The actual subtype is needed among other
25874 places when the selected component appears in the context of a loop
25875 bound, and denotes a packed array.
25876 (Operator_Check): Always use the first subtype in the
25877 error message, to avoid the appearance of internal base types.
25878 (Transform_Object_Operation): Copy each actual in full
25879 to the parameter associations of the constructed call, rather than
25880 using the shallow copy mechanism of New_Copy_List. This ensures that
25881 the chaining of named associations is done properly.
25882 (Complete_Object_Operation): Rewrite node, rather than
25883 replacing it, so that we can trace back to the original selected
25886 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
25887 and calls that use object notation, if the called function is not
25888 declared in a withed unit, place the elaboration constraint on the
25889 unit in the context that makes the function accessible.
25890 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
25891 imposes an elaboration constraint between two packages.
25893 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25895 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
25896 views of a private type after handling its private dependents, to
25897 maintain proper stack discipline between entry and exit from the
25900 2005-02-09 Cyrille Comar <comar@adacore.com>
25902 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

25907 * s-tporft.adb (Register_Foreign_Thread): Initialize Task_Image[_Len]
25908 fields for foreign threads.
25910 2005-02-09 Doug Rupp <rupp@adacore.com>
25912 * s-vaflop.adb: Add pragma Warnings (Off) to eliminate infinite
25913 recursion warnings when compiled with -gnatdm.
25915 2005-02-09 Robert Dewar <dewar@adacore.com>
25917 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
25918 Slight fix to documentation of -gnaty with no parameters
25920 * xr_tabls.ads: Add ??? comment for missing overall comment
25922 * xsinfo.adb: Make default file name be sinfo.h, since this is what
25923 we now use by default.
25925 * xsnames.adb: Adjust end of file test to look for five space followed
25926 by '#' instead of six spaces. The format of xsnames.adb was modified
25927 in the last update.
25929 * a-numeri.ads: Add reference to AI-388 for greek letter pi
25932 * clean.adb: Minor reformatting.
25934 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
25935 gnatname.adb: Minor reformatting
25936 Add 2005 to copyright output when utility is run
25938 * csets.adb: Eliminate obsolete comment
25940 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
25943 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
25945 2005-02-09 Sergey Rybin <rybin@adacore.com>
25947 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
25948 the difference between compact and incompact layout and add the record
25949 representation clause to the example illustrating different layouts.
25950 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
25951 component clauses").
25953 2005-02-09 Florian Villoing <villoing@adacore.com>
25955 * gnat_ugn.texi: Fix typos.
25956 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
25958 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
25959 in the generated documentation.
25961 2005-02-09 Arnaud Charlet <charlet@adacore.com>
25963 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
25965 Update linker wrapper when linking with non GNU C++.
25967 2005-02-09 Pascal Obry <obry@adacore.com>
25970 Document the procedure to debug the DllMain routine on Windows.
25971 Add note about -funwind-tables and mixed Ada and C/C++ programming in
25973 Document new BIND qualifer /RETURN_CODES=VMS.
25975 2005-02-09 Ben Brosgol <brosgol@adacore.com>
25977 * gnat_ugn.texi: Wordsmithing of "GNAT and Libraries" chapter
25978 Edited gnatmetric chapter

25993 * s-osinte-vxworks.ads (taskPriorityGet): Add this function (imported
25994 from the VxWorks kernel) that is needed for getting the active
25995 priority of the different tasks.
25997 * s-atacco.ads, s-atacco.adb (Nothing): Remove this dummy procedure.
25998 Use a pragma Elaborate_Body in the spec file instead.
25999 Noticed by code reading.
26001 2005-02-09 Thomas Quinot <quinot@adacore.com>
26003 * exp_util.ads: Minor correction in comment.
26005 2005-02-09 Arnaud Charlet <charlet@adacore.com>
26007 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
26008 since this procedure is now too complex to be worth inlining.
26010 2005-02-09 Richard Henderson <rth@redhat.com>
26012 * utils.c (gnat_define_builtin): Remove.
26013 (gnat_install_builtins): Use build_common_builtin_nodes.

26603 (Post_Parse_Context_Clause): Get Resolved_Path as a case-sensitive path.
26604 When comparing with project paths on the stack, first put the resolved
26605 path in canonical case.
26606 (Parse_Single_Project): Set the path name of the project file in the
26607 tree to the normalized path.
26609 * prj-proc.ads, prj-proc.adb (Check, Recursive_Check, Process): Remove
26610 parameter Process_Languages, no longer needed.
26611 (Recursive_Check): Call Prj.Nmsc.Check, instead of Ada_Check and
26612 Other_Languages_Check.

26615 to store the resolved canonical path of the project file.
26616 Remove dependency to Prj.Com, no longer needed
26618 * prj-util.adb: Adapt to name changes in package Prj
26619 (Current_Spec_Suffix => Ada_Spec_Suffix, Current_Body_Suffix =>
26622 * snames.ads, snames.adb: New standard names: Ada_Roots, Binder_Driver,
26623 Compiler_Driver, Compiler_Kind, Compute_Dependency, Default_Linker,
26624 Externally_Built, Include_Option, Language_Processing.
26626 * makegpr.adb: Numerous changes due to changes in packages
26629 * gnatls.adb: Add the default project dir (<prefix>/log/gnat) by
26630 default to the project path, except whe "-" is one of the directories

26638 * gnat1drv.adb (Gnat1drv): If debug flag A set, then automatically
26641 * repinfo.adb (List_Rep_Info): Remove special handling of -gnatdA
26642 flag. No longer needed now that we handle this in gnat1drv.adb.

26651 TYPE_SIZE_UNIT of result type if SIZE is not specified.
26652 (make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation
26653 of a bitfield, which we know is useless and causes trouble because of
26654 alignment implications.

26658 (process_attributes): Clear DECL_COMMON again when a section attribute
26660 (finish_record_type): Independently track if RECORD_TYPE has SIZE and/or
26661 SIZE_UNIT already set and use to compute final SIZE and SIZE_UNIT.
26662 (create_field_decl): Special case ADDRESSABLE negative to mean
26663 "no bitfield creation", to be used by make_aligning_type. Don't
26664 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
26665 fields claimed addressable still have to be bitfields. Use
26666 value_factor_p instead of a raw binop construction to check for the
26667 position's alignment.
26669 2004-12-07 Geert Bosch <bosch@adacore.com>
26671 * eval_fat.adb: Revert previous change.

26674 Ed Schonberg <schonberg@adacore.com>
26676 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
26677 with an implicit dereference as its prefix, use
26678 Insert_Explicit_Dereference instead of merely rewriting the prefix into
26679 an explicit dereference. This ensures that a reference to the original
26680 prefix is generated, if appropriate.
26682 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
26683 dereference is rewritten to an explicit one, generate a reference to
26684 the entity denoted by its prefix using the original prefix node, so
26685 the dereference can be properly recorded as a read of the denoted
26686 access value, if appropriate.
26688 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
26689 emitting 'assigned but never read' warning on a variable on the basis
26690 that it has an access type.

26700 * exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
26701 leaving call unchanged.
26702 This deals with the case where the pragma Import specified
26703 an external name, to be handled by the back end.
26705 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
26706 subprogram which is Imported with convention Intrinsic if an
26707 External_Name argument is specified.
26708 (Process_Import_Or_Interface): Properly diagnose link name argument.
26709 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
26710 with Sem_Ch6.Cannot_Inline.
26711 (Process_Inline): Provide separate warning for inapplicable inline
26713 (Cannot_Inline): Reject subprograms that have an at_end handler, so that
26714 treatment is uniform on different targets.

26718 * exp_ch7.adb (Expand_Cleanup_Actions): If statement sequence of
26719 construct is rewritten, preserve end label to permit source navigation.

26729 for generation of DSA code targeted to the PolyORB PCS.
26730 (Add_Stub_Type): Rewrite to isolate the parts that are specific to one
26731 implementation of the partition communication subsystem in ancillary
26733 (Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,
26734 PolyORB_Support.Build_Stub_Type): New subrograms containing the
26735 PCS-specific part of Add_Stub_Type.
26736 (Insert_Partition_Check): Use runtime library function to perform
26739 * rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref
26740 (RE_Same_Partition): New entity, from s-parint.
26742 * s-parint.ads, s-parint.adb (Same_Partition): New subprogram.

26759 2004-12-07 Ed Schonberg <schonberg@adacore.com>
26762 (Generate_Reference): Handle properly a reference to an entry formal,
26763 when an accept statement has a pragma Unreferenced for it.
26765 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
26766 and the Has_Pragma_Unreferenced flag for each formal before analyzing
26767 the body, to ensure that warnings are properly emitted for each accept
26768 statement of a given task entry.

26795 (Prepend): Remove pragma Inline.
26796 (Remove_Next): Same cleanup
26798 2004-12-07 Thomas Quinot <quinot@adacore.com>
26800 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
26801 used to record an implicit dereference as a read operation on its
26802 prefix when operating under -gnatc. Necessary to avoid spurious
26803 'variable assigned but never read' warnings in that mode.
26804 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
26805 is a non-overloaded implicit dereference, call the above subprogram to
26806 ensure proper recording of references.
26808 2004-12-07 Gary Dismukes <dismukes@adacore.com>
26810 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
26811 to be resolved later as part of Analyze_Iteration_Scheme's call to

26858 2004-12-07 Vincent Celier <celier@adacore.com>
26860 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
26861 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
26862 and -eit to -ept. Added qualifier
26863 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
26865 2004-11-27 Andreas Schwab <schwab@suse.de>
26867 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
26869 2004-11-25 Arnaud Charlet <charlet@adacore.com>
26871 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
26872 internal implementation unit GNAT.Sockets.Thin,
26873 as their usage for sockets is non-portable (using the read and write
26874 functions from the system runtime library is fine on UNIX but won't
26875 work under Windows).
26877 * mingw32.h: Update copyright notice.
26879 2004-11-25 Arnaud Charlet <charlet@adacore.com>

26928 (Setup_Exception): Do nothing in the GNAT SJLJ case.
26930 * gigi.h (others_decl, all_others_decl): New decls representing the
26931 new Others_Value and All_Others_Value objects.
26932 (struct attrib): Rename "arg" component as "args", since GCC expects a
26933 list of arguments in there.
26935 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
26936 corresponding objects exported by a-exexpr, instead of hardcoded dummy
26939 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
26940 others_decl and all_others_decl instead of hardcoded dummy addresses
26941 to represent "others" and "all others" choices, which is cleaner and
26942 more flexible with respect to the possible eh pointer encoding policies.
26944 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
26945 (process_attributes): Account for the naming change of the "args"
26946 attribute list entry component.
26948 * decl.c (build_attr_list): Rename into prepend_attributes to allow
26949 cumulating attributes for different entities into a single list.
26950 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
26951 attributes for the current entity and propagate first subtype
26952 attributes to other subtypes.
26953 <E_Procedure>: Attribute arguments are attr->args and not
26954 attr->arg any more.
26955 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
26956 argument provided, as this is what GCC expects. Use NULL_TREE instead

26994 (First_RCI_Subprogram_Id): Document this constant.
26995 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
26997 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
26998 replaced with calls to Get_Library_Unit_Name_String. Previously there
26999 were several instances of the same code in different locations in the
27000 compiler; this checkin completes the replacement of all of these
27001 instances with calls to a common subprogram.
27002 Minor reformatting.
27004 * sem_dist.adb: Remove comment noting that RPC receiver generation
27005 should be disabled for RACWs that implement RASs.

27036 nodes are improperly shared.
27038 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
27039 pragmas to Exp_Prag, which is more appropriate.
27040 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to

27045 that are functions return universal values, that have to be converted
27046 to the context type.
27047 Use new Make_String_Literal function with string.
27048 (Get_Stream_Convert_Pragma): New function, replaces the use of
27049 Get_Rep_Pragma, which had to be kludged to work in this case.
27051 * freeze.adb: Use new Has_Rep_Pragma function
27053 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
27054 function with string.
27055 Use new Has_Rep_Pragma function.

27079 Robert Dewar <dewar@adacore.com>
27081 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
27082 discriminant of a constrained subtype, analyze the copy of the
27083 corresponding constraint, because in some cases it may be only
27084 partially analyzed.
27085 Removes long-lived ??? comments.
27087 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
27088 handled controlled or secondary-stack expressions within the
27089 iteration_scheme of a loop.
27091 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
27092 bounds that may contain functions calls, to prevent memory leaks when
27093 the bound contains a call to a function that uses the secondary stack.
27094 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
27095 generate temporaries for loop bounds that might contain function calls
27096 that require secondary stack and/or finalization actions.
27098 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
27099 selected component and the selector is overloadable (not just a
27100 function) treat as function call, Analyze_Call will disambiguate if
27102 (Analyze_Selected_Component): Do not generate an actual subtype for the
27103 selected component if expansion is disabled. The actual subtype is only
27104 needed for constraint checks.
27105 (Analyze_Allocator): If restriction No_Streams is set, then do
27106 not permit objects to be declared of a stream type, or of a
27107 composite type containing a stream.
27109 * restrict.ads: Remove the a-stream entry from Unit_Array, since
27110 No_Streams no longer prohibits with'ing this package.
27112 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
27113 discriminants, but the parent base has unknown discriminants, there is
27114 no discriminant constraint to inherit. Such a discrepancy can arise
27115 when the actual for a formal type with unknown discriminants is a
27116 similar private type whose full view has discriminants.
27117 (Analyze_Object_Declaration): If restriction No_Streams is set, then
27118 do not permit objects to be declared of a stream type, or of a
27119 composite type containing a stream.
27121 2004-11-18 Ed Schonberg <schonberg@adacore.com>
27123 * exp_dbug.ads: Update documentation to reflect simpler encoding for
27124 protected operations.
27126 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
27127 generated name, it complicates decoding in gdb and hinders debugging
27128 of protected operations.
27129 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
27130 flag for the protected entry barrier function.
27131 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
27132 flag for the protected entry function.
27134 2004-11-18 Nicolas Setton <setton@adacore.com>
27136 * expect.c: Define __unix__ when __APPLE__ is defined.
27138 * Makefile.in: Inform the value of the variable GMEM_LIB in the
27139 Darwin-specific section.
27141 * lang-specs.h: Change the placement of the %1 marker.
27142 Works around the fact that gcc adds -fPIC by default under Darwin.
27144 2004-11-18 Ed Schonberg <schonberg@adacore.com>
27146 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
27147 type of the object with the packed array type, set the Analyzed flag
27148 on the object if it is an entity or simple indexed component, to avoid
27149 spurious type errors.
27151 2004-11-18 Gary Dismukes <dismukes@adacore.com>
27153 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
27154 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
27155 separate line from the version message.
27157 2004-11-18 Ed Falis <falis@adacore.com>
27159 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
27161 (init_float): Eliminate initialization of floating point status for
27162 AE653. The instructions have no effect for vThreads.
27164 2004-11-18 Vincent Celier <celier@adacore.com>
27166 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
27167 gnatbind is invoked with -shared.
27169 2004-11-18 Jose Ruiz <ruiz@adacore.com>
27171 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
27172 for Detect_Blocking which is redundant with the check done within the
27173 procedure Protected_Single_Entry_Call.
27174 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
27175 Detect_Blocking which is redundant with the check done within the
27176 procedure Protected_Single_Entry_Call.
27178 2004-11-18 Vincent Celier <celier@adacore.com>
27180 * makegpr.adb (Compile): Put the compiling switches (in package
27181 Compiler and on the command line) immediately after "-c", instead of
27182 at the end of the command line invocation of the compiler, when
27183 compiling a non-Ada file.
27184 (Build_Global_Archive): When there is no need to rebuild the archive,
27185 set Global_Archive_Exists, so that the archive is passed to the linker
27188 2004-11-18 Robert Dewar <dewar@adacore.com>
27189 Sergey Rybin <rybin@adacore.com>
27192 Remove extra paren check from list of checks for redundant constructs
27193 Add documentation of new -gnatyx style check (check extra parens)
27194 Remove paragraph about gnatelim debug options.
27196 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
27197 objects rather than forbidding dependencies on the package Ada.Streams.
27199 * sinfo.ads: Add ??? note that we should document pragmas passed to
27202 * g-expect.ads: Fix a few typos in the comments.
27204 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
27206 * misc.c (gnat_handle_option): Use %< and %> for quoting in
27209 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
27211 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
27213 2004-11-07 Andreas Schwab <schwab@suse.de>
27215 * Makefile.in (install-gnatlib): Remove spurious hyphen.
27217 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
27220 * Makefile.in (darwin): Set soext to .dylib.
27222 2004-10-26 Vincent Celier <celier@gnat.com>
27223 Thomas Quinot <quinot@act-europe.fr>
27225 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
27226 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
27227 there is no use of GNAT.Sockets.Constants.
27228 Remove remaining pragma Import for C_Write
27229 Remove C_Read and C_Write from internal implementation unit
27230 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
27231 the read and write functions from the system runtime library is fine
27232 on UNIX but won't work under Windows).
27234 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
27235 (Check_Selector): Use C_Recv instead of C_Read.
27236 Selectors are the GNAT.Sockets abstraction to perform a select()
27237 call on a set of descriptors. To allow abortion of an ongoing
27238 select operation, some data is written to a dedicated socket that
27239 is always monitored.
27240 Under Windows, the write and read library functions cannot operate
27241 on sockets, so we need to use send and recv instead, which is portable
27242 across all supported platforms.
27244 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
27245 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
27246 (using the read and write functions from the system runtime library is
27247 fine on UNIX but won't work under Windows).
27249 2004-10-26 Nicolas Setton <setton@act-europe.fr>
27251 * mlib-tgt-darwin.adb: New file.
27253 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
27254 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
27255 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
27256 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
27259 * Makefile.in: Add support for building shared libraries under Darwin.
27260 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
27261 the low level EH init subprogram to be called from __gnat_initialize.
27263 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
27264 indicates which options to pass to the archive indexer.
27266 * mlib-utl.adb: Add support for calling ranlib with additional
27267 options. This is needed for instance under Mac OS X.
27268 (Ranlib_Options): New global variable, used to store the potential
27269 options to pass to ranlib.
27270 (Ar): Use Ranlib_Options when spawning ranlib.
27271 (Initialize): Set the value of ranlib option.
27273 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
27275 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
27276 instead of 8K, to reflect the real potential needs for stack-checking
27279 2004-10-26 Pascal Obry <obry@gnat.com>
27281 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
27283 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
27284 Windows only the initial thread stack size can be set so it is good to
27285 start we a low stack size.
27286 The OS will adjust the size as needed.
27288 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
27289 Nicolas Setton <setton@act-europe.fr>
27291 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
27292 "__unix__" instead of "unix".
27293 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
27294 sections were just mistakenly ignored. The former is
27295 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
27296 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
27297 of hpux. This prevents an unwanted definition of the symbol
27298 convert_addresses in adaint.o.
27300 2004-10-26 Gary Dismukes <dismukes@gnat.com>
27302 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
27303 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
27305 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27307 * a-filico.ads, a-filico.adb: fix incorrect header.
27309 2004-10-26 Javier Miranda <miranda@gnat.com>
27311 * a-ststio.ads: Fix typo in identifier
27313 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27315 * sem_ch4.adb: Minor reformatting.
27317 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27319 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
27320 enabled, check the result of unary and binary operations when the
27321 expression is the right-hand side of an assignment.
27323 2004-10-26 Vincent Celier <celier@gnat.com>
27325 * clean.adb (Delete): Do not output warnings when in quiet output and
27326 not in verbose mode.
27327 (Force_Deletions): New Boolean flag, defaulted to False
27328 (Delete): Only delete a file if it is writable, and when
27329 Force_Deletions is True.
27330 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
27331 (Usage): Line for new switch -f
27332 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
27335 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
27337 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
27338 JM type only if its size matches that of the wrapper. When a size is
27339 prescribed and the field is not aliased, remove the wrapper of a JM
27340 type only if the size is not greater than that of the packed array.
27341 (gnat_to_gnu_entity): Change the extension of packed array wrappers
27344 2004-10-26 Geert Bosch <bosch@gnat.com>
27346 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
27347 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
27348 (Pred): Implement in terms of Succ.
27350 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27352 * exp_aggr.adb (Safe_Component): An aggregate component that is an
27353 unchecked conversion is safe for in-place use if the expression of the
27354 conversion is safe.
27355 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
27356 be expandable in place even if the aggregate does not come from source.
27357 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
27358 designated object of an allocator in place, rather than building it
27359 first on the stack. The previous scheme forces a full copy of the array,
27360 and may be altogether unsusable if the size of the array is too large
27361 for stack allocation.
27363 2004-10-26 Robert Dewar <dewar@gnat.com>
27365 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
27366 compares if the component is atomic.
27368 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
27369 array assignment if the component type is atomic.
27371 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27372 Eric Botcazou <ebotcazou@act-europe.fr>
27374 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
27375 is aliased and is a by_reference type, do not pass by copy.
27376 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
27377 detect whether the call is in the right side of an assignment or
27378 the expression of an object declaration. Recurse on component
27379 association within aggregates.
27380 Call it in the condition that determines whether the temporary is
27381 necessary for correct stack-checking.
27383 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27385 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
27386 RACW_Type, used in the PolyORB version.
27387 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
27388 version and the GARLIC version.
27390 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
27391 Rename RCI_Info to RCI_Locator for better consistency between the
27392 GARLIC and PolyORB versions of the distributed systems annex.
27393 (DSA_Implementation_Name): This enumeration lists the possible
27394 implementations of the Partition Communication Subsystem for the
27395 Distributed Systems Annex (DSA). The three available implementations
27396 are the dummy stub implementation (No_DSA), and two versions based on
27397 two different distribution runtime libraries: GARLIC and PolyORB. Both
27398 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
27400 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
27403 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
27404 between the GARLIC and PolyORB versions of the distributed systems
27406 Remove RE_Unbounded_Reclaim_Pool since it is unused.
27408 2004-10-26 Gary Dismukes <dismukes@gnat.com>
27410 * gnat1drv.adb: Suppress calling the back end when
27411 Frontend_Layout_On_Target is true.
27413 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27415 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
27416 Set_Read_Only): New subprograms.
27417 These new routines allow the user to set or unset the Owner execute
27418 and Owner write permission flags on a file.
27420 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
27421 GNAT.OS_Lib.Set_Executable instead of rolling our own.
27423 2004-10-26 Matthew Gingell <gingell@gnat.com>
27425 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
27427 2004-10-26 Pascal Obry <obry@gnat.com>
27429 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
27430 memory before the faulting page we properly test the process read
27431 access for this address using appropriate Win32 routine.
27432 (HPUX sections): guard with "__hpux__" instead of "hpux".
27434 2004-10-26 Robert Dewar <dewar@gnat.com>
27436 * lib-xref.adb (Generate_Reference): Don't complain about reference to
27437 entry parameter if pragma Unreferenced set, since we do not properly
27438 handle the case of multiple parameters.
27440 2004-10-26 Vincent Celier <celier@gnat.com>
27442 * prj-env.adb: (Contains_ALI_Files): New Boolean function
27443 (Ada_Objects_Path.Add): For a library project, add to the object path
27444 the library directory only if there is no object directory or if the
27445 library directory contains ALI files.
27446 (Set_Ada_Paths.Add.Recursive_Add): Ditto
27448 2004-10-26 Vincent Celier <celier@gnat.com>
27450 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
27451 extension of library projects.
27453 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
27454 path defaults to ".:<prefix>/lib/gnat".
27455 (Parse): For an extending all project, allow direct import of a project
27456 that is virtually extended.
27458 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
27459 the specified name is directly imported, return its ID. Otherwise, if
27460 an extension of this project is imported, return the ID of the
27463 2004-10-26 Robert Dewar <dewar@gnat.com>
27465 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
27466 (Sub3): New procedure, used by Scaled_Divide
27467 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
27468 correct more than one instance of failure to propagate carries
27470 (Double_Divide): Handle overflow case of largest negative number
27471 divided by minus one.
27473 * s-arit64.ads (Double_Divide): Document that overflow can occur in
27474 the case of a quotient value out of range.
27477 2004-10-26 Robert Dewar <dewar@gnat.com>
27479 * s-bitops.adb (Bit_Eq): Remove redundant check.
27481 * s-bitops.ads: Minor comment updates
27482 Change some occurrences of Address to System.Address
27484 * s-carsi8.ads: Fix minor cut-and-paste error in comments
27486 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27488 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
27489 accessibility check to prefix that is a protected operation.
27491 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27493 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
27494 empty, post message on stub.
27496 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27497 Javier Miranda <miranda@gnat.com>
27499 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
27500 current instance appears within a unit that is directly in the context
27502 Used to determine whether the body of the instance should be analyzed
27503 immediately after its spec, to make its subprogram bodies available
27504 for front-end inlining.
27505 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
27506 constraint is not allowed on the component type (AARM 12.5.3(3))
27508 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27510 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
27511 'Storage_Pool): enhance, document & limit detection of non-sharable
27514 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
27516 * s-pooglo.ads: Add more documentation now that this pool is properly
27519 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27521 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
27522 or protected type with discriminants, do not constrain the
27523 corresponding record type if the subtype declaration has no
27524 discriminant constraints. This can be the case in source code, or in
27525 the subtype declaration created to rename an actual type within an
27528 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27530 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
27531 different kind of stub (possibly wrong name for file), do not check
27533 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
27534 includes call to some function that returns an unconstrained type, do
27537 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27539 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
27540 appear in the code for the main unit. Dependencies among units in the
27541 context of the main unit are established when those other units are
27542 compiled. Otherwise spurious elaboration constraints can generate
27543 incorrect elaboration circularities.
27545 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27546 Ed Schonberg <schonberg@gnat.com>
27548 * sem_util.adb (Is_Aliased_View): Defend against the case where this
27549 subprogram is called with a parameter that is not an object name. This
27550 situation arises for some cases of illegal code, which is diagnosed
27551 later, and in this case it is wrong to call Is_Aliased, as that might
27552 cause a compiler crash.
27553 (Explain_Limited_Type): Refine previous fix to include
27554 inherited components of derived types, to provide complete information.
27556 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
27557 is the prival for a protected object.
27558 It is necessary to mark this entity as a variable, in addition to
27559 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
27560 modified to avoid checking the Aliased flag on entities that are not
27561 objects. (Checking that flag for non-objects is erroneous and could
27562 lead to a compiler crash).
27564 2004-10-26 Robert Dewar <dewar@gnat.com>
27566 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
27567 X_Frac = 0.5, then we know that the number X must be positive.
27568 (Succ): Remove the same redundant test, and also fix the primary test
27569 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
27571 (Decompose): Add fuller comments to spec
27573 2004-10-26 Pascal Obry <obry@gnat.com>
27575 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
27576 validity (process must have read access). Set to 0 in all other cases.
27577 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
27578 violation on Win32.
27579 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
27580 segmentation violation.
27582 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
27584 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
27585 whose type is a constructed subtype of an aliased object with an
27586 unconstrained nominal subtype, convert the actual to the constructed
27587 subtype before taking its address.
27589 2004-10-26 Vincent Celier <celier@gnat.com>
27591 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
27592 (Is_Path_Name_Case_Sensitive): New function
27594 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure

27601 Vincent Celier <celier@gnat.com>
27603 * gnat_ugn.texi: Generalize "finding memory problems" section into a
27604 "memory management issues" section and document some of the useful
27605 memory pools provided as part of the GNAT library.
27606 Remove "virtual" from declaration of A::method2 in
27607 the simple example of Ada/C++ mixed system.
27608 Library Projects may be virtually extended: their virtual extensions
27609 are not Library Projects.
27610 Added section on extending project hierarchies.
27612 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
27614 * adaint.c (__gnat_get_libraries_from_registry): Cast value

27636 other x86 platforms).
27638 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
27640 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
27641 in general and triggers stack alignment adjustment for thread entry
27642 points on targets where this is necessary.
27644 2004-10-04 Bernard Banner <banner@gnat.com>
27647 * Makefile.in: Add section for powerpc linux
27648 Add variant i-vxwork-x86.ads

27652 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
27654 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
27655 table registration calls when need be. Ensures no reference to the crt
27656 ctors symbol are issued in the SJLJ case, which avoids possible
27657 undefined symbol errors in the case of modules to be statically linked
27660 2004-10-04 Javier Miranda <miranda@gnat.com>
27662 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
27663 in-line the code corresponding to subprogram Analyze_Actuals. In
27664 addition, analyze the actuals only in case of subprogram call.

27679 (Analyze_Block_Statement): Add circuitry to detect following dead code
27680 (Check_Unreachable_Code): Handle case of block exit
27682 2004-10-04 Robert Dewar <dewar@gnat.com>
27684 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
27685 (XMatchD): Avoid warning for Logic_Error call
27687 2004-10-04 Robert Dewar <dewar@gnat.com>
27689 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
27690 consider expressions buried within a procedure actual to be an actual.
27691 This caused some blowups with uses of packed slices within a procedure
27694 2004-10-04 Robert Dewar <dewar@gnat.com>
27696 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
27697 longer need to be initialized to zero.
27698 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
27699 initialized to zero.
27701 * checks.adb (Expr_Known_Valid): Packed arrays are now always
27702 considered valid, even if the representation is modular. That's correct
27703 now that we no longer initialize packed modular arrays to zero.
27705 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
27706 suffixes. These are now documented as the only cases in which the
27707 debugger ignores outer records.
27708 Previously, the spec allowed arbitrary suffixes for this purpose.
27709 Change name of LJM to JM for packed array pad records
27710 Create separate section on packed array handling, and add a whole new
27711 set of comments to this section describing the situation with packed
27712 modular types and justification requirements depending on endianness.
27714 2004-10-04 Robert Dewar <dewar@gnat.com>
27716 * a-except.adb: Add a comment for last change
27718 * einfo.ads: Minor spelling correction in comment
27720 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting

27730 Inline_Always when in Configurable_Run_Time mode.
27732 * sem_prag.adb (Process_Convention): If entity is an inherited
27733 subprogram, apply convention to parent subprogram if in same scope.
27734 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
27735 when in Configurable_Run_Time mode.
27737 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27739 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
27740 class_wide type after component list has been inherited.

27745 Denotes_Previous_Actual, to handle properly the case of a private
27746 actual that is also the component type of a subsequent array actual.
27747 The visibility status of the first actual is not affected when the
27748 second is installed.
27749 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
27750 make fully recursive the treatment of formals of packages declared
27752 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
27753 the above on exit from an instantiation.
27754 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
27755 current instantiation which is now complete.
27756 (Analyze_Package_Instantiation): No instantiated body is needed if the
27757 main unit is generic. Efficient, and avoid anomalies when a instance
27758 appears in a package accessed through rtsfind.
27760 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27762 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
27763 do not generate a declaration for a temporary if the call is part of a
27764 library-level instantiation.
27766 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27768 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
27769 searching for a limited component to flag.
27771 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
27772 expansion of Input, to account for the fact that the implicit call
27773 generated by the attribute reference must freeze the user-defined
27774 stream subprogram. This is only relevant to 'Input, because it can
27775 appear in an object declaration, prior to the body of the subprogram.
27777 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
27778 expansion can proceed and further errors uncovered.
27779 (Minor clean up): Fix cases of using | instead of \ for continuation
27782 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27784 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
27786 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
27787 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.

27790 * decl.c (gnat_to_gnu_entity, case object): Check and process a
27791 specified alignment before validating size.
27792 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
27793 stripped-down declaration for the type of the inner field when making
27796 * utils.c (finish_record_type): Do not compute the size in units
27797 incrementally. Instead compute it once for the rep clause case.
27798 Use gcc_assert and gcc_unreachable.
27800 2004-10-04 Vincent Celier <celier@gnat.com>
27802 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
27804 (Is_Valid_Path_Name): Take '/' as a directory separator.
27806 2004-10-04 Vincent Celier <celier@gnat.com>
27808 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
27809 (Extended_Project) only if Extended_Project is defined, to avoid
27811 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
27813 (Parse_Single_Project): Ditto.
27815 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
27816 Add_To_Project_Path for virtual projects.
27818 2004-10-04 Vincent Celier <celier@gnat.com>
27820 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

27824 parameter Options_2.
27826 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
27827 Build_Dynamic_Library with an empty Options_2.
27829 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
27832 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
27833 directory separator, if any.
27834 (Gprmake): Do not allow mains on the command line for library projects.
27835 Do not attempt to link when the project is a library project.
27836 (Library_Opts): New table to store Library_Options.
27837 (Build_Library): If Library_Options is specified, pass these options
27838 when building a shared library.

27849 corresponding to the Preallocated_Stacks flags in System.
27850 (Get_Target_Parameters): Including the processing for
27851 Preallocated_Stacks.

27859 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
27860 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
27861 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
27862 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
27863 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
27864 used to signal whether the compiler creates the required stacks and
27865 descriptors for the different tasks (when True) or it is done by the
27866 underlying operating system at run time (when False).
27867 It is initially set to False in all targets.
27869 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
27870 if it is supported by the target.
27871 (Make_Task_Create_Call): Pass the stack address if it has been
27872 previously created. Otherwise pass a Null_Address.
27874 * snames.adb: Add _stack.

27877 statically allocated task stacks.
27879 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
27880 Stack_Address argument.
27881 Check that its value is equal to Null_Address because this target does
27882 not support the static stack allocation.
27884 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
27886 * usage.adb: Change "pragma inline" to "pragma Inline" in information

27891 * exp_dist.adb: Split declaration of asynchronous flag out of
27892 Add_RACW_Read_Attribute.
27893 Minor reformatting for better alignment with PolyORB version.
27894 Store the entity for the asynchronous flag of an RACW, rather than the
27895 expression, in the asynchronous flags table. This will allow this flag
27896 to be used in other subprograms beside Add_RACW_Read_Attribute.
27898 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
27900 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

27904 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
27905 sockets constant MSG_NOSIGNAL (Linux-specific).
27906 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
27907 all Send operations.
27908 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
27909 from trigerring SIGPIPE.
27910 Rename components to avoid clash with Ada 2005 possible reserved
27912 (Check_Selector): When the select system call returns with an error
27913 condition, propagate Socket_Error to the caller.
27915 2004-10-01 Jan Hubicka <jh@suse.cz>
27917 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

27927 Minor reformatting.
27929 * freeze.adb (Check_Address_Clause): Remove previous change, not the
27930 right way of doing things after all.
27931 (Freeze_Entity): For object, set Is_Public for imported entities
27932 unless there is an address clause present.
27934 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
27936 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
27937 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
27938 ensures proper handling of types with rep clauses, which might have
27939 their TYPE_SIZE set already.
27941 2004-09-21 Robert Dewar <dewar@gnat.com>
27943 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
27944 packed array types in both little- and big-endian cases. This change
27945 ensures that we no longer count on the unused bits being initialized
27946 for such types (and in particular ensures that equality testing will
27947 only read the relevant bits).
27948 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
27949 These changes mean that we no longer need to initialize small packed
27951 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
27952 optimization to an LJM field as to its parent field.
27954 * ada-tree.h, trans.c, utils.c, utils2.c:
27955 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
27957 2004-09-20 Jan Hubicka <jh@suse.cz>
27959 * utils.c (gnat_finalize): Remove.
27960 (end_subprog_body): Directly call cgraph_finalize_function;
27961 do not lower the nested functions.
27963 2004-09-20 Robert Dewar <dewar@gnat.com>
27966 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
27967 if an address clause is present, since that means that the Import
27970 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
27972 * 5tsystem.ads: Removed, no longer used.
27974 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>

27996 an existing directory.
27997 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
27998 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
27999 Convert the result to File_Size.
28001 * prj.ads: (Project_Error): New exception
28003 * prj-attr.adb: Except in procedure Initialize, Fail comes from
28004 Prj.Com, not from Osint.
28005 (Attrs, Package_Attributes): Tables moved to private part of spec
28006 (Add_Attribute, Add_Unknown_Package): Moved to new child package
28008 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
28009 Prj.Project_Error after call to Fail.
28010 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
28011 Fail. Check that package name is not already in use.
28013 * prj-attr.ads: Comment updates to indicate that all subprograms may be
28014 used by tools, not only by the project manager, and to indicate that
28015 exception Prj.Prj_Error may be raised in case of problem.
28016 (Add_Unknown_Package, Add_Attribute): Moved to new child package
28018 (Attrs, Package_Attributes): Table instantiations moved from the body to
28019 the private part to be accessible from Prj.Attr.PM body.

28022 from new package Prj.Attr.PM.
28023 (Parse_Attribute_Declaration): Call Add_Attribute from new package
28026 * Makefile.in: Add prj-attr-pm.o to gnatmake object list

28074 pragmas recognized by GNAT.
28076 * gnat_rm.texi: Document pragma Detect_Blocking.
28078 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,

28108 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
28109 raise Program_Error if called from a protected operation, and increase
28110 the protected action nesting level.

28127 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
28128 protected action nesting level.
28130 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
28131 insertion of the statement raising Program_Error. The run time
28132 contains the required machinery for handling that.
28134 * sem_util.ads: Change comment associated to procedure
28135 Check_Potentially_Blocking_Operation.
28136 This procedure does not insert a call for raising the exception because
28137 that is currently done by the run time.
28139 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
28141 * init.c: Add the global variable __gl_detect_blocking that indicates
28142 whether pragma Detect_Blocking is active (1) or not (0). Needed for

28149 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
28151 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
28152 DB is found in the ali file. Any unit compiled with pragma
28153 Detect_Blocking active forces its effect in the whole partition.
28155 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
28156 Detect_Blocking is active and delay is called from a protected
28159 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
28160 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
28161 Detect_Blocking is active (0 otherwise).

28166 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
28168 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
28169 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
28172 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
28173 (Register_Receiving_Stub): Add Subp_Info formal parameter.
28174 Update API in placeholder implemetation of s-parint to reflect changes
28175 in distribution runtime library.
28177 * sem_ch3.adb (Expand_Derived_Record): Rename to
28178 Expand_Record_Extension.
28180 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
28181 primitive operations of potentially distributed object types that have
28182 non-controlling anonymous access formals.
28184 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
28186 New implementation of expansion for remote access-to-subprogram types,
28187 based on the RACW infrastructure.
28188 This version of sem_dist is compatible with PolyORB/DSA as well as
28191 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
28192 Asynchrronous that applies to a remote access-to-subprogram type, mark
28193 the underlying RACW type as asynchronous.
28195 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
28196 __gnat_using_gnu_linker to 1.
28198 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
28199 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

28205 * exp_ch3.adb (Expand_Derived_Record): Rename to
28206 Expand_Record_Extension.
28207 (Build_Record_Init_Proc.Build_Assignment): The default expression in
28208 a component declaration must remain attached at that point in the
28209 tree so New_Copy_Tree copies it if the enclosing record type is derived.
28210 It is therefore necessary to take a copy of the expression when building
28211 the corresponding assignment statement in the init proc.
28212 As a side effect, in the case of a derived record type, we now see the
28213 original expression, without any rewriting that could have occurred
28214 during expansion of the ancestor type's init proc, and we do not need
28215 to go back to Original_Node.
28217 * exp_ch3.ads (Expand_Derived_Record): Rename to
28218 Expand_Record_Extension.
28220 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

28223 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
28224 New subprograms. Used to create a proxy tagged object for a remote
28225 subprogram. The proxy object is used as the designated object
28226 for RAS values on the same partition (unless All_Calls_Remote applies).
28227 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
28228 System.Partition_Interface.Get_Unique_Remote_Pointer.
28229 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
28230 Renamed from Add_RAS_*_Attribute.
28231 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
28233 New implementation of expansion for remote access-to-subprogram types,
28234 based on the RACW infrastructure.
28236 * exp_dist.ads (Copy_Specification): Update comment to note that this
28237 function can copy the specification from either a subprogram
28238 specification or an access-to-subprogram type definition.
28240 2004-09-09 Ed Schonberg <schonberg@gnat.com>
28242 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
28243 in an instance, between an explicit subprogram an one inherited from a
28244 type derived from an actual.
28246 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
28247 add a polling call if the subprogram is to be inlined by the back-end,
28248 to avoid repeated calls with multiple inlinings.
28250 * checks.adb (Apply_Alignment_Check): If the expression in the address
28251 clause is a call whose name is not a static entity (e.g. a dispatching
28252 call), treat as dynamic.
28254 2004-09-09 Robert Dewar <dewar@gnat.com>
28256 * g-trasym.ads: Minor reformatting
28258 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

28269 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
28270 enable map file generation. Add the right option to generate the map
28271 file if Map_File is set to True.
28273 * gnatdll.adb (Gen_Map_File): New variable.
28274 (Syntax): Add info about new -m (Map_File) option.

28294 * opt.adb (Set_Opt_Config_Switches): Use Ada_Version_Runtime to compile
28297 * opt.ads: Add Ada_Version_Runtime constant used to decide which
28298 version of the language is used to compile the run time.

28302 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
28303 of variable length temporaries for function return now that the
28304 back-end and gigi support it.

28379 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
28380 pragma Debug as an if statement with a constant condition, for
28381 consistent treatment of entity references contained within the
28382 enclosed procedure call.
28384 2004-09-01 Vincent Celier <celier@gnat.com>
28386 * bindgen.adb: (Set_EA_Last): New procedure
28387 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure

28418 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
28419 target names rewrite to fix regressions with recent version of

28473 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
28474 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
28475 option and not mdll anymore. Update comment.
28477 2004-08-16 Pascal Obry <obry@gnat.com>
28479 * bld.adb (Put_Include_Project): Properly handle directory separators
28482 2004-08-16 Ed Schonberg <schonberg@gnat.com>

28497 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
28498 for a global aliased object with a variable size and an unconstrained
28499 nominal subtype, pretend there is no initializer if the one we have is
28500 incomplete, and avoid referencing an inexistant component in there. The
28501 part we have will be rebuilt anyway and the reference may confuse
28502 further operations.

28522 2004-08-13 Ed Schonberg <schonberg@gnat.com>
28524 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
28525 unit, this is an attempt to inline a construct that is not available in
28526 the current restricted mode, so abort rather than trying to continue.
28528 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
28529 discriminants that rename those of the parent, recover names of
28530 original discriminants for the constraint on the full view of the
28532 (Complete_Private_Subtype): Do not create a subtype declaration if the
28533 subtype is an itype.
28535 * gnat_rm.texi: Added section on implementation of discriminated
28536 records with default values for discriminants.
28538 2004-08-13 Ed Schonberg <schonberg@gnat.com>

28558 new specification and test explicitly for non-zero return value.
28560 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
28561 returning C.int, to avoid using a derived boolean type.
28563 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
28564 Duplicate_Subexpr_No_Checks in preference to direct use of
28565 Remove_Side_Effects and New_Copy_Tree.

29161 loop with an explicit exit statement, to avoid generating an

29173 controller type, or an assignment of a record type with controlled

30516 interpretations for rewritten right operand.
30517 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

31155 * config-lang.in (boot_language, build_by_default): Set

31221 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
31222 overriding, use the operation of the parent unconditionally.
31224 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
31225 operation when either operand is a literal, to avoid further
31228 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
31229 overridden by a previous explicit declaration, mark the previous entity

31282 single string literal for pragma arguments.

31294 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was

31299 limitation on length of lines when scanning config pragma files.

32473 * eval_fat.adb (Machine): Remove unnecessary suppression of warning.
32474 (Leading_Part): Still perform truncation to machine number if the
32475 specified radix_digits is greater or equal to machine_mantissa.
32477 2004-04-05 Javier Miranda <miranda@gnat.com>
32479 * par-ch3.adb: Complete documentation of previous change
32480 Correct wrong syntax documentation of the OBJECT_DECLARATION rule
32481 (aliased must appear before constant).
32483 * par-ch4.adb: Complete documentation of previous change.
32485 * par-ch6.adb: Complete documentation of previous change.
32487 * sinfo.ads: Fix typo in commment.
32489 2004-04-05 Ed Schonberg <schonberg@gnat.com>
32491 * sem_ch3.adb (Inherit_Components): If derived type is private and has
32492 stored discriminants, use its discriminants to constrain parent type,
32493 as is done for non-private derived record types.
32495 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
32496 Ada 2005 AI-310: an abstract non-dispatching operation is not a
32497 candidate interpretation in an overloaded call.
32499 * tbuild.adb (Unchecked_Convert_To): Preserve conversion node if
32500 expression is Null and target type is not an access type (e.g. a
32501 non-private address type).
32503 2004-04-05 Thomas Quinot <quinot@act-europe.fr>
32505 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
32506 statement whose right-hand side is an inlined call, save a copy of the
32507 original assignment subtree to preserve enough consistency for
32508 Analyze_Assignment to proceed.
32510 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
32511 complete assignment subtree which is now unnecessary, as the expansion
32512 of inlined call has been improved to preserve a consistent assignment
32513 tree. Note_Possible_Modification must be called only
32514 after checks have been applied, or else unnecessary checks will
32517 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
32518 of explicit dereferences that do not Come_From_Source:
32519 - be selective on cases where we must go back to the dereferenced
32520 pointer (an assignment to an implicit dereference must not be
32521 recorded as modifying the pointer);
32522 - do not rely on Original_Node being present (Analyze_Assignment
32523 calls Note_Possible_Modification on a copied tree).
32525 * sem_warn.adb (Check_References): When an unset reference to a pointer
32526 that is never assigned is encountered, prefer '<pointer> may be null'
32527 warning over '<pointer> is never assigned a value'.

32536 * 5gmastop.adb (Pop_Frame): Comment out the pragma Linker_Option for
32537 libexc. We currently don't reference anything in this library and
32538 linking it in triggers linker warnings we don't want to see.
32540 * init.c: Update comments.

32581 2004-04-01 Robert Dewar <dewar@gnat.com>
32583 * checks.adb: Minor reformatting throughout
32584 Note that prev checkin added RM reference to alignment warning
32586 2004-04-01 Ed Schonberg <schonberg@gnat.com>
32588 * exp_aggr.adb (Get_Component_Val): Treat a string literal as
32589 non-static when building aggregate for bit-packed array.
32591 * exp_ch4.adb (Expand_N_Slice): If a packed slice is an actual of a
32592 function call that is itself the actual in a procedure call, build
32595 * exp_pakd.adb (Expand_Bit_Packed_Element_Set): If right-hand side is
32596 a string literal, create a temporary for it, constant folding only
32597 handles scalars here.
32599 2004-04-01 Vincent Celier <celier@gnat.com>
32601 * ali-util.adb (Post_Scan, Error_Msg, Error_Msg_S, Error_Msg_SC,

32612 instead of at the beginning.
32614 * osint.adb (Lib_File_Name): Use Multi_Unit_Index_Character, not '~'
32616 (Osint package elaboration): Change Multi_Unit_Index_Character to '$' if
32619 * osint.ads (Multi_Unit_Index_Character): New Character global variable

32712 * sem_aggr.adb: (Check_Can_Never_Be_Null): New subprogram
32713 (Aggregate_Constraint_Checks): Generate conversion to the null-excluding
32714 type to force the corresponding run-time check

32773 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
32775 * osint.adb (Executable_Prefix): Set Exec_Name to the current
32776 executable name when not initialized. Otherwise, use its current value.
32778 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
32779 initialize it to another executable name than the current one. This
32780 allows to configure paths for an executable name (gnatmake) different
32781 from the current one (gnatdist).
32783 2004-03-29 Ed Schonberg <schonberg@gnat.com>
32785 * exp_ch6.adb (Expand_Call): A call to a function declared in the
32786 current unit cannot be inlined if it appears in the body of a withed
32787 unit, to avoid order of elaboration problems in gigi.
32789 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
32790 information for protected (wrapper) operation as well, to simplify gdb
32793 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
32794 protected body, indicate that the entity for the generated spec comes
32795 from source, to ensure that references are properly generated for it.
32796 (Build_Body_To_Inline): Do not inline a function that returns a

32800 apply convention to homonyms that are declared explicitly.
32802 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
32803 that renames an equality operator and the operands are overloaded,
32804 resolve them with the declared formal types, before rewriting as an
32807 2004-03-29 GNAT Script <nobody@gnat.com>

32830 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
32832 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
32833 attribute reference does not denote a subtype, it can be any
32834 expression that has a classwide type, potentially after an implicit
32835 dereference. In particular, the prefix can be a view conversion for
32836 a classwide type (for which Is_Object_Reference holds), but it can
32837 also be a value conversion for an access-to-classwide type. In the
32838 latter case, there is an implicit dereference, and the original node
32839 for the prefix does not verify Is_Object_Reference.
32841 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
32842 conversion of a discriminant-dependent component of a mutable object
32845 2004-03-25 Ed Schonberg <schonberg@gnat.com>
32847 * freeze.adb (Freeze_Entity): When an inherited subprogram is
32848 inherited, has convention C, and has unconstrained array parameters,
32849 place the corresponding warning on the derived type declaration rather
32850 than the original subprogram.
32852 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
32853 indication on renaming declaration, if formal has a box and actual
32856 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
32857 determine whether to generate an implicit or explicit reference to
32858 the renamed entity.

32861 subprogram renaming comes from a defaulted formal subprogram in an
32864 2004-03-25 Gary Dismukes <dismukes@gnat.com>
32866 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
32867 value expressions to ensure that calls within a component definition
32868 will be checked (since those are evaluated during the record type's
32871 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>

32919 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
32920 declaration for a child subprogram body that acts as a spec, indicate
32921 that the entity in the declaration needs debugging information.
32923 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
32924 full view if the subtype is created for a constrained record component;
32925 gigi has enough information to construct the record, and there is no
32926 place in the tree for the declaration.
32928 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
32929 serial number for the dummy body that is built for analysis, to avoid
32930 inconsistencies in the generation of internal names when compiling

32966 * ada-tree.h: Update copyright notice.
32967 Minor reformatting.
32969 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
32971 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
32972 as regular exception objects and not as mere integers representing the
32973 condition code. The latter approach required some dynamics to mask off
32974 severity bits, which did not fit well into the GCC table based model.
32975 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
32976 exception data objects. We don't it and it would conflict with the other
32977 external symbol we have to generate for such exceptions.
32979 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
32980 the special code for VMS exceptions, since these are now represented
32981 as regular exceptions objects.
32983 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
32985 * decl.c (debug_no_type_hash): Remove.

33024 When needed (stack checking) the stack size is retrieved
33025 from the VxWorks kernel.

33115 imaginary parts, use Double precision throughout.
33117 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
33118 we want to be able to compile run-time with -gnata for testing, but
33119 this may also be instantiated in user code that is compiled with -gnata.

33152 New accessors to allow easy access to GNAT exception data
33154 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the

33188 taken care of in Scan_Make_Arg.
33189 (Scan_Make_Arg): Add the executable suffix only if the argument
33190 following -o, in canonical case, does not end with the executable

33214 corresponding dispatch entry is properly initialized.
33215 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
33216 when looking for user-defined equality operation.

33272 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
33273 Insert_Dereference_Action when rewriting an implicit dereference into
33274 an explicit one, this will be taken care of during expansion of the
33275 explicit dereference.
33276 (Expand_N_Slice): Same. Always do the rewriting, even for the case
33277 of non-packed slices, since the dereference action generated by
33278 expansion of the explicit dereference is needed in any case.

33280 analyze and resolve the rewritten explicit dereference so it is seen
33282 (Insert_Dereference_Action): This procedure is now called only for the
33283 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
33284 dereferences that do not come from source (including explicit

34165 checks for bitfield creation are triggered.
34166 (finish_record_type): During last pass over the fields, clear
34167 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

34607 Minor reformatting and code clean ups.
34608 Minor changes to prevent -gnatwa warnings
34610 * ali.adb: Minor reformatting and cleanup of code
34611 Acquire new SS indication of secondary stack use from ali files
34613 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
34614 (since now we expect this to be done for imported functions)
34616 * bindgen.adb: Generate call to modify default secondary stack size if
34619 * bindusg.adb: Add line for new -D switch
34621 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
34622 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
34623 Add circuitry for both records and arrays to avoid gigi
34624 processing if the type involved has non-bit-aligned components
34626 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
34627 N_String_Literal node always references an E_String_Literal_Subtype
34628 entity. This may not be true in the future.
34629 (Possible_Bit_Aligned_Component): Move processing of
34630 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
34632 * exp_ch6.adb (Expand_Thread_Body): Pick up
34633 Default_Secondary_Stack_Size as variable so that we get value modified
34634 by possible -Dnnn binder parameter.
34636 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
34637 (Type_May_Have_Bit_Aligned_Components): New function.
34639 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.
34640 (Type_May_Have_Bit_Aligned_Components): New function.

34647 importing constant atomic/volatile objects.
34648 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
34649 unless explicit Pure_Function pragma given, to avoid insidious bug of
34650 call to non-pure imported function getting eliminated.
34652 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb,
34653 gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,
34654 gnatxref.adb, gprcmd.adb, gprep.adb, make.adb: Minor reformatting

34668 New switch Sec_Stack_Used (GNAT, GNATBIND)
34669 Make Default_Secondary_Stack_Size a variable instead of a constant,
34670 so that it can be modified by the new -Dnnn bind switch.
34672 * rtsfind.adb (Load_Fail): Give full error message in configurable
34673 run-time mode if all_errors mode is set. This was not done in the case
34674 of a file not found, which was an oversight.
34675 Note if secondary stack unit is used by compiler.
34677 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
34678 ineffective elaborate all pragmas on non-visible packages (this
34679 happened when a renamed subprogram was called). Now the elaborate all
34680 always goes on the package containing the renaming rather than the one
34681 containing the renamed subprogram.
34683 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
34684 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
34686 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
34687 has an Etype that references an E_String_Literal.
34688 (Eval_String_Literal): Avoid assumption that N_String_Literal node
34689 always references an E_String_Literal_Subtype entity. This may not
34690 be true in the future.
34692 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
34695 * sem_res.adb (Resolve): Specialize msg for function name used in proc
34698 2004-01-05 Ed Falis <falis@gnat.com>
34700 * g-debuti.adb: Replaced direct boolean operator with short-circuit
34703 2004-01-05 Vincent Celier <celier@gnat.com>
34705 * bld.adb: Minor comment updates
34706 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
34709 * make.adb (Gnatmake): Special process for files to compile/check when
34710 -B is specified. Fail when there are only foreign mains in attribute
34711 Main of the project file and -B is not specified. Do not skip bind/link
34712 steps when -B is specified.
34714 * makeusg.adb: Document new switch -B
34716 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
34718 * switch-m.adb: (Scan_Make_Switches): Process -B switch
34720 * vms_data.ads: Add new GNAT PRETTY qualifier

34732 has size that overflows.
34734 2004-01-05 Gary Dismukes <dismukes@gnat.com>
34736 * exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
34737 -gnatwa warning on static condition.
34739 2004-01-05 Doug Rupp <rupp@gnat.com>
34741 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
34743 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
34745 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
34746 all attributes, including read-only attribute.
34748 2004-01-05 Pascal Obry <obry@gnat.com>

34751 library naming scheme.
34753 * mlib-prj.adb (Build_Library): Generate different names for the static
34754 or dynamic version of the GNAT runtime. This is needed to support the
34755 new shared library naming scheme.
34756 (Process_Binder_File): Add detection of shared library in binder file
34757 based on the new naming scheme.
34759 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
34760 scheme for the shared runtime libraries.
34763 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
34765 (install-gnatlib): Do not create symlinks for shared libraries.
34766 (gnatlib-shared-default): Idem.
34767 (gnatlib-shared-dual-win32): New target. Not used for now as the
34768 auto-import feature does not support arrays/records.
34769 (gnatlib-shared-win32): Do not create copy for the shared libraries.
34770 (gnatlib-shared-vms): Fix shared runtime libraries names.
34772 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
34773 dependent runtime shared library name.
34775 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
34777 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
34780 2004-01-05 Ed Schonberg <schonberg@gnat.com>
34782 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
34783 protected objects when allocator has a subtype indication, not a
34784 qualified expression. Note that qualified expressions may have to be
34785 checked when limited aggregates are implemented.
34787 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
34788 pure, emit warning.
34789 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
34790 subprogram is imported, remove warning.
34792 2004-01-05 Geert Bosch <bosch@gnat.com>
34794 * s-poosiz.adb: Update copyright notice.
34795 (Allocate): Use Task_Lock to protect against concurrent access.
34796 (Deallocate): Likewise.

34830 Ada.Exceptions.Last_Chance_Handler.
34832 2003-12-17 Sergey Rybin <rybin@act-europe.fr>
34834 * cstand.adb (Create_Standard): Change the way how the declaration of
34835 the Duration type is created (making it the same way as it is for all
34836 the other standard types).
34838 2003-12-17 Robert Dewar <dewar@gnat.com>
34840 * s-crtl.ads: Fix header format
34841 Change Pure to Preelaborate

34846 the expression type only if it is declared in the current unit.
34848 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
34849 are universal and already analyzed, as can occur in constrained
34850 subcomponents that depend on discriminants, when one constraint is a
34853 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
34854 type Any_Fixed is legal as the argument of a conversion, if only one
34855 fixed-point type is in context.

34866 2003-12-15 Vincent Celier <celier@gnat.com>
34868 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
34869 (Gnatchop): Do not set failure status when reporting the number of
34872 2003-12-15 Doug Rupp <rupp@gnat.com>
34874 * s-ctrl.ads: New file.
34876 * Makefile.rtl (GNAT_RTL_NONTASKING_OBJS): Add s-crtl$(objext).

34896 2003-12-11 Ed Falis <falis@gnat.com>
34898 * 5zinit.adb: Clean up.
34900 * 5zintman.adb (Notify_Exception): replaced case statement with a call
34901 to __gnat_map_signal, imported from init.c to support
34902 signal -> exception mappings that depend on the vxWorks version.
34905 Created and exported __gnat_map_signal to support signal -> exception
34906 mapping that is dependent on the VxWorks version.

34935 Minor reformatting throughout
34937 2003-12-11 Ed Schonberg <schonberg@gnat.com>
34939 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
34940 bounds of a loop, create a separate block in order to generate proper
34941 cleanup actions to prevent memory leaks.
34943 * sem_res.adb (Resolve_Call): After a call to
34944 Establish_Transient_Scope, the call may be rewritten and relocated, in
34945 which case no further processing is needed.
34947 * sem_util.adb: (Wrong_Type): Refine previous fix.
34948 Fixes ACATS regressions.
34951 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
34954 2003-12-08 Jerome Guitton <guitton@act-europe.fr>

34957 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
34960 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
34963 2003-12-08 Robert Dewar <dewar@gnat.com>
34965 * 7sintman.adb: Minor reformatting
34967 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
34968 standard linker options to get standard libraries linked. We now plan
34969 to provide dummy versions of these libraries to match the appropriate
34970 configurable run-time (e.g. if a library is not needed at all, provide
34971 a dummy empty library).
34973 * targparm.ads: Configurable_Run_Time mode no longer affects linker
34974 options (-L parameters and standard libraries). What we plan to do is
34975 to provide dummy libraries where the libraries are not required.
34977 * gnatbind.adb: Minor comment improvement
34979 2003-12-08 Javier Miranda <miranda@gnat.com>
34981 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
34982 aggregate in the parent. Otherwise constants with limited aggregates
34983 are not supported. Add new formal to pass the component type (Ctype).
34984 It is required to call the corresponding IP subprogram in case of
34985 default initialized components.
34986 (Gen_Assign): In case of default-initialized component, generate a
34987 call to the IP subprogram associated with the component.
34988 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
34989 of aggregate with default initialized components.
34990 (Has_Default_Init_Comps): Improve implementation to recursively check
34991 all the present expressions.
34993 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
34994 to indicate that the initialization call corresponds to a
34995 default-initialized component of an aggregate.
34996 In case of default initialized aggregate with tasks this parameter is
34997 used to generate a null string (this is just a workaround that must be
34998 improved later). In case of discriminants, this parameter is used to
34999 generate a selected component node that gives access to the discriminant
35002 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
35003 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
35004 allocated aggregates with default-initialized components.
35006 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
35007 the box notation is used in positional aggregates.

35025 Set the scanner to return ends of line and comments as tokens, if
35026 Store_Comments is True.
35027 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
35028 comments are associated with these nodes. Store the node IDs in the
35030 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
35032 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
35033 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
35034 current project. Call Tree.Restore afterwards. Set the various nodes
35035 for comment storage (Next_End, End_Of_Line, Previous_Line,
35038 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
35039 defaulted to False.
35041 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
35042 to False. When Truncated is True, truncate the string, never go to the
35044 (Write_End_Of_Line_Comment): New procedure
35045 (Print): Process comments for nodes N_With_Clause,
35046 N_Package_Declaration, N_String_Type_Declaration,
35047 N_Attribute_Declaration, N_Typed_Variable_Declaration,
35048 N_Variable_Declaration, N_Case_Construction, N_Case_Item.
35049 Process nodes N_Comment.
35051 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
35052 without comments and there are some comments, set the flag
35053 Unkept_Comments to True.
35054 (Scan): If there are comments, set the flag Unkept_Comments to True and
35055 clear the comments.
35056 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
35057 (Next_End_Nodes: New table
35058 (Comment_Zones_Of): New function
35059 (Scan): New procedure; moved from Prj. Accumulate comments in the

35082 * scng.ads, scng.adb (Comment_Is_Token): New Boolean global variable,
35083 defaulted to False.
35084 (Scan): Store position of start of comment. If comments are tokens, set
35085 Comment_Id and set Token to Tok_Comment when scanning a comment.
35086 (Set_Comment_As_Token): New procedure
35088 * sinput-p.adb: Update Copyright notice
35089 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
35090 that no longer exists.
35092 2003-12-08 Javier Miranda <miranda@gnat.com>
35094 * sem_aggr.adb: Add dependence on Exp_Tss package
35095 Correct typo in comment
35096 (Resolve_Aggregate): In case of array aggregates set the estimated
35097 type of the aggregate before calling resolve. This is needed to know
35098 the name of the corresponding IP in case of limited array aggregates.
35099 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
35100 in case of default initialized array components.

38814 referring concrete lexical entities (keywords, attribute names
38815 etc.), and @syntax for ARM grammar elements. Use @r for English
38816 text in comments. Use @emph for emphasis. Change "if-statements"

38832 function call could reallocate the table which was being indexed
38833 using its result). Fixes ada/4851.

39200 2001-12-17 Laurent Pautet <pautet@gnat.com>
39203 Fix comment of Shutdown_Socket and Close_Socket. These functions
39204 should not fail silently because if they are called twice, this
39205 probably means that there is a race condition in the user program.
39206 Anyway, this behaviour is consistent with the rest of this unit.
39207 When an error occurs, an exception is raised with the error message
39208 as exception message.

40510 2001-10-11 Pascal Obry <obry@gnat.com>
40512 * impunit.adb: Add GNAT.CRC32.
40514 2001-10-11 Ed Schonberg <schonber@gnat.com>
40516 * exp_fixd.adb (Expand_Multiply_Fixed_By_Fixed_Giving_Fixed): handle

40531 2001-10-11 Pascal Obry <obry@gnat.com>
40534 (GNAT_ADA_OBJS): add g-crc32.o, a-tags.o, a-stream.o
40535 (GNATBIND_OBJS): add g-crc32.o, a-tags.o, a-stream.o
40536 (GNATLS_RTL_OBJS): add g-crc32.o
40537 (GNATMAKE_RTL_OBJS): add g-crc32.o
40540 (CRC_Match): new function.
40541 (Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
40542 instead of the previous simple checksum algorithm.
40543 (Time_Stamp_Mismatch): use CRC_Match for comparison.
40544 (Set_Source_Table): idem.
40547 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
40548 instead of simple checksum.
40549 (CRC_Match): new function.
40550 (CRC_Error): new constant.
40552 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
40553 a CRC now and not a simple checksum. A CRC uses lower-case hex
40554 letters, fixes ambiguity in parsing.
40556 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
40557 is what this variable will store.
40559 * bcheck.adb: Change reference to chechsum in comments by CRC.
40560 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
40561 rename All_Checksum_Match to All_CRC_Match. Change due to API
40562 renaming since now GNAT does not use a simple checksum but a
40563 CRC using GNAT.CRC32.
40565 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
40566 now and not anymore a simple checksum.
40568 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
40571 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
40574 (Restore_Scan_State): rename Checksum to CRC.

40579 (Checksum): rename to CRC.
40580 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
40582 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
40583 GNAT.CRC32). Update copyright notice.
40585 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
40586 GNAT.CRC32). Update copyright notice.
40589 (Accumulate_Checksum): removed.
40590 (Update): new procedure. Add a wide-character into the CRC.

40597 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
40598 Source_CRC in S initialization.

40602 * sinput.ads (Source_Checksum): renamed to Source_CRC.
40603 Update comments for the CRC.
40605 * types.adb (Hex): Use lowercase for the letter part.
40607 * types.ads (Get_Hex_String): Returns the hexadecimal representation
40608 for a word. This is currently used only for CRC. In previous version,
40609 the checksum was using a representation with all letter being
40610 upper-case. With the new implementation (using CRC) we do not remove
40611 the 32th bit of the CRC, so we can have an upper-case starting letter
40612 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
40613 It is ambigous since the CRC was optional and could be followed by
40614 options like EB, EE. So now this routines uses lower-case letter for
40615 the hexadecimal representation. Strange enough only lower case letters
40616 where checked in Scan_ALI (even if this was not a possible case).
40618 * gnatvsn.ads (Library_Version): changed to 3.15a.
40620 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
40623 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
40626 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
40627 Add 2001 to copyright notice
40628 (Accumulate_Checksum): Modify to use System.CRC32.
40630 * ali-util.ads: Redo changes of previous revision to continue to use
40631 the word Checksum. Add 2001 to copyright notice.
40633 * ali.adb: Undo some of previous changes, not needed.
40634 Keep the change for lower case letters in the checksum.
40636 * ali.ads: Undo previous change not needed.
40638 * bcheck.adb: Undo most of previous change, not needed.
40639 But do use Checksums_Match for checksum comparison.
