1785 of changing its type in place.

1929 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1930 Orig_Prev to Prev in the case where the actual is N_Function_Call or
1931 N_Identifier. This was interfering with other cases that are rewritten
1932 as N_Identifier, such as allocators, resulting in passing of the wrong
1933 accessibility level, and based on testing this code is apparently no
1934 longer needed at all.

2136 * s-stausa.adb (Fill_Stack): Stack_Used_When_Filling is now stored

2252 * prj-part.adb, prj-part.ads, prj.adb, prj.ads, prj-env.adb:

2256 Minimum_Linker_Options as they are no longer set.
2257 Remove function There_Are_Ada_Sources from package Prj and move code

4025 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4026 convention from its base type, do not set the type to that of integer,
4027 because it may inherit a size clause.
4028 Warn on a size clause with a size different
4029 from that of Integer, if the type has convention C.

4093 New local subprogram Is_Valid_Remote_Object_Type, replaces
4094 Is_Recursively_Limited_Private.
4095 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4096 non-controlling formals (and the return type, even though this is not
4097 explicit in the standard) must support external streaming.

4105 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4106 Is_Remote_Call_Interface to identify RACW types in a stable and
4107 consistent way. We used to rely in this predicate on the privateness of
4108 the designated type and its ancestors, but depending on the currently
4109 visible private parts, this caused false negatives. We now uniformly
4110 rely on checks made at the point where the RACW type is declared.

4124 Add missing escaping of all-caps word 'CPP' in error messages.
4125 (Build_Discriminated_Subtype): Do not inherit representation clauses
4126 from parent type if subtype already carries them, because they are
4127 inherited earlier during derivation and already include those that may
4128 come from a partial view.
4130 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4131 Check the declarations of a subprogram body for proper deferred

4166 operation of an RACW stub type (these primitives are only executed
4167 through dispatching, never through static calls).
4168 (Collect_Interps): When only one interpretation has been found, set N's
4169 Entity and Etype to that interpretation, otherwise Entity and Etype may
4170 still refer to an interpretation that was ignored by Add_One_Interp,
4171 in which case would end up with being marked as not overloaded but with
4172 an Entity attribute not pointing to its (unique) correct interpretation.

8432 WITH clause on a private sibling.
8433 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8434 child unit is a renaming, create an implicit with_clause on that

8537 perform subtype conformance between the formals of the current entry
8538 and those of the target interface primitive.
8539 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8540 Timed_Entry_Call): Analyze the triggering statement as the first step of
8541 the processing. If this is a dispatching select, postpone the analysis
8542 of all select statements until the Expander transforms the select. This
8543 approach avoids generating duplicate identifiers after the Expander has
8544 replicated some of the select statements. In case the Expander is
8545 disabled, perform regular analysis.
8546 (Check_Triggering_Statement): New routine.
8547 (Analyze_Requeue): Exclude any interpretations that are not entries when
8548 checking overloaded names in a requeue. Also test type conformance for
8549 matching interpretations rather than requiring subtype conformance at

9144 multiple inherited interfaces info. This information cannot be stored
9145 in Xref_Entity_Record, which only supports a single instance of Tref_*,

9162 additional management on these nodes in Expand_Interface_Actuals.
9164 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9165 that handles use of 'Access and 'Unchecked_Access applied to

9211 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9212 used by VxWorks targets to have access to task-specific data and be
9213 able to extract the stack boundaries for stack checking.

9257 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9258 association for an access component, add an association with null as
9259 the expression. Remove testing for array subtypes and the setting in
9260 that case of Ctyp to the array component type, which prevented proper
9261 inclusion of an association for null-initialized arrays. Collapse
9262 condition that tests for array subtypes into just a test of
9263 Is_Partially_Initialized_Type (which already covers arrays anyway).

9280 * sem_ch4.adb: Minor code and comment reformatting.
9281 (Analyze_Allocator): When the designated type of an unconstrained

9446 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9448 * a-calend-vms.adb, a-calend.adb:
9449 Add a section on leap seconds control along with two entities used to
9450 enable and disable leap seconds support. The array Leap_Second_Times is
9451 now constant and contains hard time values pre-generated. Remove
9452 all elaboration code used to populate the table of leap seconds.
9455 Add entity Leap_Seconds_Support to the list of global run-time variables
9456 along with a comment on its usage and values.
9457 (Gen_Adainit_Ada): Add code to generate the declaration and import of
9458 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
9459 or one (enabled) depending on the presence of binder switch "-y".
9460 (Gen_Adainit_C): Add code to generate the declaration of external int
9461 __gl_leap_seconds_support. Set is value to zero (disabled) or one
9462 (enabled) depending on the presence of binder switch "-y".

9471 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
9472 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
9474 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
9476 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
9477 function which can be called by the debugger to interrupt the tasks of
9478 an Ada application asynchronously, as needed on VxWorks.
9479 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
9481 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
9482 renamed from Stop_All_Tasks. Update comments.
9483 (Stop_All_tasks): New function declaration.
9485 2007-09-26 Olivier Hainque <hainque@adacore.com>
9487 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
9488 #include <utime.h> and #define GCC_RESOURCE_H before
9489 #include <sys/wait.h>.
9490 Add more protections in __gnat_translate_vms.
9492 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
9493 #include <sys/wait.h>.
9495 2007-09-26 Thomas Quinot <quinot@adacore.com>
9496 Sergey Rybin <rybin@adacore.com>
9498 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
9500 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9503 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9505 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9508 * sem_dist.ads: Minor comment fix
9510 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9512 2007-09-26 Javier Miranda <miranda@adacore.com>
9513 Eric Botcazou <ebotcazou@adacore.com>
9516 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9517 indirection added to the HT_Link component of the TSD. This is required
9518 to statically allocate the TSD.
9521 Minor reordering of the declarations in the private part. Required to
9522 add a level of indirection to the contents of the TSD component HT_Link.
9523 This is required to statically allocate the TSD.
9525 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9526 Is_Statically_Allocated set from constant objects.
9527 Do not make exported constants created by the compiler volatile.
9528 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9531 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9532 before returning them.
9534 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9535 public part of the package.
9536 (Make_DT): Move HT_Link component out of the TSD record. For this
9537 purpose Make_DT now declares a separate object that stores the
9538 HT_Link value, and initializes the TSD component with the address
9539 of this new object. The addition of this level of indirection is
9540 required to statically allocate the TSD because the TSD cannot
9541 have variable components.
9542 (Expand_Interface_Conversion): Improve the expanded code.
9543 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9545 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9546 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9547 if we are building static dispatch tables then we must not generate
9548 extra code to register the primitive because the dispatch table will
9549 be built at the end of the library package; otherwise we notify that
9550 we cannot build the static dispatch table.
9552 2007-09-26 Robert Dewar <dewar@adacore.com>
9554 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
9557 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
9558 (Analyze_Record_Representation_Clause): Suppress junk warning for
9559 missing component clause.

9569 for thunks associated with interface types.
9571 * einfo.ads: Improve documentatation of Is_Internal
9572 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9573 associated with interface types.
9574 Extensive comment fixes regarding flags that appear in all entities. The
9575 documentation is now consistent for all such flags (there were a number
9576 of errors in the documentation in this regard).
9578 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9580 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9581 of these procedures are passed a function call that already has
9582 build-in-place actuals (testing new flag
9583 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9584 the case where processing continues.
9585 (Expand_Call): If the call is generated from a thunk body then we
9586 propagate the extra actuals associated with the accessibility
9587 level of the access type actuals.
9589 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9590 of each extra formal of a protected operation to reference the
9591 corresponding extra formal of the subprogram denoted by the
9592 operation's Protected_Body_Subprogram.
9594 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9595 N_Function_Call nodes.
9597 2007-09-26 Robert Dewar <dewar@adacore.com>
9599 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9601 * debug.adb: Add d.s flag.
9603 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9605 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9606 debug variable so that it won't be initialized when pragma
9607 Initialize_Scalars is in effect.
9609 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9611 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9612 initialization of a full view. This is moved to
9613 Analyze_Package_Specification.
9615 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9616 preelaborable initialization of a full view in entity loop.
9617 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9618 its child units are use-visible only if they are visible child units.
9620 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9621 whether an expression can be used within a type declaration that
9622 requires preelaborable init.
9623 (Check_Components): Replace inline code that does partial checking for
9624 preelaborable default expressions with call to
9625 Is_Preelaborable_Expression.
9626 (Has_Preelaborable_Initialization): In the case of a generic actual
9627 subtype, (that is, Is_Generic_Actual is True), return the result of
9628 applying Has_Preelaborable_Initialization to the generic actual's base
9631 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9633 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9634 call to Jan_1_Day _Of_Week to optimize its performance.
9635 (Is_Leap): Move the routine to the scope of Week_In_Year.
9636 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9637 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9638 avoids calling Time_Of and Split, thus making it more efficent.
9639 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9641 * g-calend.ads (Week_In_Year): Change comment to reflect new
9644 2007-09-26 Emmanuel Briot <briot@adacore.com>
9646 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9647 Command_Line): New types
9648 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9649 support for defining how switches can be grouped on a command line (as
9650 is the case for -gnatw... for GNAT), and how simple switches can be
9651 used as aliases for more complex switches (-gnatwa is same as
9653 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9654 (Start, Current_*): New subprograms
9655 Added support for parsing an array of strings in addition to the real
9657 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9658 be moved from the body to the private part of the spec.
9659 (*): All subprograms now have an extra parameter with default value to
9660 specify which parser should be used. For backward compatibility, it
9661 defaults to parsing the command line of the application. They were also
9662 modified to properly handle cases where each of the argument does not
9663 start at index 1 (which is always true for Ada.Command_Line, but not
9664 when processing any Argument_List).
9665 (Free): New subprogram
9666 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9667 Argument): New subprograms
9668 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9669 special characters like ':', '=',... are now handled in a single place,
9670 which makes the code more extensible eventually.
9671 (Getopt, Full_Switch): When the switch was returned as part of the
9672 special character '*', make sure it is prepended by the switch character
9673 ('-' in general), so that the application knows whether "foo" or "-foo"
9674 was specified on the command line.
9676 2007-09-26 Florian Villoing <villoing@adacore.com>
9678 * g-dirope.adb (Remove_Dir): In case we are removing directories
9679 recursively, make sure that if an exception is raised during the
9680 processing, the current working directory is reset to its initial
9681 value before propagating the exception.
9683 2007-09-26 Vincent Celier <celier@adacore.com>
9685 * gnatbind.adb: If there are several ALI files specified and there is
9686 a main program to bind, the first ALI is expected to contain the main
9687 subprogram and the names of the binder generated files will be derived
9688 from the first ALI file name.
9689 (Gnatbind): Fix insertion character in invocation of Error_Msg
9691 2007-09-26 Vincent Celier <celier@adacore.com>
9693 * gnatcmd.adb (Check_Files): Do not include sources that have been
9694 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9696 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9698 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9699 information about each of its index types, following the type
9700 reference for its component type.
9702 2007-09-26 Vincent Celier <celier@adacore.com>
9704 * make.adb: (Kill): New procedure (__gnat_kill imported)

9706 were previously local to procedure Compile_Sources.
9707 (Sigint_Intercepted): Send signal SIGINT to all outstanding
9708 compilation processes.

9711 sources, so that the correct paths will be found.
9713 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
9715 2007-09-26 Vincent Celier <celier@adacore.com>
9717 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9719 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9720 Replace components Compiler_Min_Options and Binder_Min_Options with
9721 Compiler_Required_Switches and Binder_Required_Switches in record
9723 Remove components Default_Language and Config in Project_Tree_Data,
9726 * prj-attr.adb: New attributes Required_Switches (<language>) in
9727 packages Compiler and Binder.
9729 * prj-nmsc.adb: Major rewrite of the processing of configuration
9730 attributes for gprbuild. No impact on GNAT tools.
9732 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9733 process configuration attributes: this is done in Prj.Nmsc.Check.
9734 (Recursive_Process): Make a full copy of packages inherited from project
9735 being extended, instead of a shallow copy.
9736 (Process_Project_Tree_Phase_1): New procedure
9737 (Process_Project_Tree_Phase_1): New procedure
9738 (Process): Implementation now uses the two new procedures
9740 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9741 from the project config, not the tree config that no longer exists.
9743 2007-09-26 Vincent Celier <celier@adacore.com>

9764 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9766 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
9767 ancestor of the derived type, the operations are inherited from the
9768 primary dispatch table of the parent.
9769 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9770 when the context is an explicit type conversion.
9772 2007-09-26 Ed Schonberg <schonberg@adacore.com>

9817 no sources, but is an extending project.
9819 2007-09-25 Eric Botcazou <ebotcazou@adacore.com>
9821 * trans.c: Fix misplaced #define.

9928 2007-09-12 Olivier Hainque <hainque@adacore.com>
9930 * decl.c (gnat_to_gnu_entity) <E_Record_Subtype>: For a subtype
9931 with discriminant constraints, generalize the code for BIT_FIELDs
9932 to PACKED fields of constant size and propagate DECL_PACKED.
9934 2007-09-11 Eric Botcazou <ebotcazou@adacore.com>
9936 * decl.c (array_type_has_nonaliased_component): New predicate.
9937 (gnat_to_gnu_field) <E_Array_Type>: Invoke the above predicate to
9938 set the TYPE_NONALIASED_COMPONENT flag on the type.
9939 <E_Array_Subtype>: Likewise.

9947 * einfo.ads, einfo.adb (Dispatch_Table_Wrapper): New attribute. Present
9948 in library level record type entities if we are generating statically
9949 allocated dispatch tables.
9951 * exp_disp.adb (Make_Tags/Make_DT): Replace previous code
9952 importing/exporting the _tag declaration by new code
9953 importing/exporting the dispatch table wrapper. This change allows us
9954 to statically allocate of the TSD.

9961 allocate the dispatch tables.
9962 (Check_Allocator): Make function iterative instead of recursive.
9963 Also return inner allocator node, when present, so that we do not have
9964 to look for that node again in the caller.

10067 Thomas Quinot <quinot@adacore.com>
10069 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
10070 create an abstract subprogram in the case of 'Input. For 'Output we now
10071 create a real spec/body when the type is abstract, since it can
10072 potentially be called.
10073 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10074 body for 'Output when the type is abstract (only the creation of the
10075 body for 'Input is excluded when the type is abstract).
10076 (Stream_Operation_OK): Add an additional condition in the return
10077 statement, so that False will be returned for TTS_Stream_Input if the
10078 associated tagged type is an abstract extension. Add comments for
10080 (Expand_N_Object_Declaration): For the case of a shared passive
10081 variable, insert init proc call only after the shared variable
10082 procedures have been processed, because the IP call needs to undergo
10083 shared passive variable reference expansion, which requires these
10084 procedures to be available (and elaborated).
10086 2007-09-10 Vincent Celier <celier@adacore.com>

10093 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
10094 given a box association, the type of the component is discriminated,
10095 and the value of the discriminant is the discriminant of the enclosing
10096 type, retrieve its value from the aggregate itself, where it must have
10099 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10100 to remove other spurious ambiguities on arithmetic operations involving
10101 literals and addresses, on systems where Address is a visible integer
10102 type, when the operator is called in functional notation.
10103 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10104 is legal when the types match, even if the operation is currently
10107 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10109 * sem_ch12.adb (Build_Local_Package): A formal package with no
10110 associations is legal if all formals have defaults. It is not
10111 equivalent to a formal declared with a box.
10113 2007-09-10 Sergey Rybin <rybin@adacore.com>

10141 2007-09-08 Eric Botcazou <ebotcazou@adacore.com>
10143 * decl.c (gnat_to_gnu_entity) <Object>: Simplify the condition under
10144 which a constant renaming is treated as a normal object declaration.
10145 * trans.c (lvalue_required_p) <N_Slice>: New case, extracted from
10146 the N_Indexed_Component case.
10147 <N_Indexed_Component>: Fall through to above case.

10222 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10224 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the

10227 Update the usage of available flag to reflect the addition of Is_Raised.
10228 (Is_Raised, Set_Is_Raised): Bodies of new routines.
10229 (Write_Entity_Flags): Write the status of flag Is_Raised.
10230 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10231 spurious ambiguities when integer literals appear in the context of an
10232 address type that is a visible integer type.
10234 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10235 exceptions never being raised.
10236 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

10244 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10246 * exp_ch3.adb (Build_Record_Init_Proc): If there is a static
10247 initialization aggregate for the type, generate itype references for
10248 thetypes of its (sub)components, to prevent out-of-scope errors in gigi.
10250 2007-08-31 Gary Dismukes <dismukes@adacore.com>
10252 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10253 library-level package renaming, pass the declaration associated with
10254 the renaming's special debug variable to Qualify_Entity_Names to ensure
10255 that its encoded name is properly qualified.
10257 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10258 occurring in the list of entities to qualify, and do not attempt to
10259 traverse an entity list in that case. Variables associated with
10260 ` library-level package renamings can now occur in the table.

10284 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10285 concatenations of string literals into a single literal, in order to
10286 avoid very deep recursion in the front end, which was causing stack
10289 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10290 string, and the right operand is a string literal (the case of "" &
10291 "..."), optimize by avoiding copying the right operand -- just use the
10292 value of the right operand directly.
10294 * stringt.adb (Store_String_Chars): Optimize by growing the
10295 String_Chars table all at once, rather than appending characters one by
10297 (Write_String_Table_Entry): If the string to be printed is very long,
10298 just print the first few characters, followed by the length. Otherwise,
10299 doing "pn(n)" in the debugger can take an extremely long time.
10301 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10302 Store_String_Char with Store_String_Chars.

10316 clauses of subunits, ignore limited_with_clauses that are illegal and
10317 have not been fully analyzed.
10319 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10321 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10322 flag, for effiency. It is called when analyzing arithmetic operators
10323 and also for actuals in calls that are universal_integers. The flag is
10324 set for the predefined type address, and for any type or subtype
10327 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10328 Universal_Integer, when the formal is a descendent of address and the
10329 call appears in user code.
10330 (Analyze_Selected_Component): if the prefix is a private extension, the
10331 tag component is visible.

10394 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10396 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10397 associated with Standard_Debug_Renaming_Type, to be used as the type of
10398 the special variables whose names provide debugger encodings for
10399 renaming declarations.
10401 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10402 (Set_Debug_Renaming_Link): Change to set Node25.
10403 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
10404 (Write_Field25_Name): Add case for E_Variable to output
10405 "Debug_Renaming_Link".
10406 (Write_Field23_Name): Correct the output string for "Limited_View".
10408 * exp_dbug.adb: Add with and use of Tbuild.
10409 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10410 and literal with creation of a variable of type
10411 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10412 and the entity of the renaming declaration.
10413 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10414 part of the name of a variable that has a Debug_Renaming_Link.
10416 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10417 special type to be associated with variables that provide debugger

10421 Ed Schonberg <schonberg@adacore.com>
10422 Javier Miranda <miranda@adacore.com>
10424 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10425 ancestor part given by an aggregate to test for an unchecked conversion,
10426 since this can occur in some cases when the ancestor part is a function
10427 call, and we don't want to fall into the recursive call to this
10428 procedure in that case.
10430 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10431 stream attributes on limited types to account for user-specified
10432 attributes as well as whether Input (resp. Output) becomes available
10433 due to Read (resp. Write) being available for the type. Change Boolean
10434 variable to the more accurate name
10435 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10436 double-"not" predicate at beginning of return statement to more
10437 understandable form.
10439 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10440 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10441 in a block statement and use that as the first statement of the
10442 expanded return rather than incorrectly using the handled sequence as
10443 the first statement.
10445 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10446 operation, generate an explicit freeze node for it rather than
10447 generating extra formals, to ensure that gigi has the proper order of
10448 elaboration for anonymous subtypes in the signature of the subprograms.
10449 (Build_In_Place_Formal): Move assertion to beginning of loop.
10450 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

10453 applied to a function call (occurs for some cases of 'Input).
10455 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10456 2005, generate an extended return statement enclosing the result object
10459 * freeze.adb (Freeze_Record_Type): Extend the current management of
10460 components that are access type with an allocator as default value: add
10461 missing support to the use of qualified expressions of the
10462 allocator (which also cause freezing of the designated type!)
10463 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10464 dispatching operation, since extra formals may be needed by calls to
10465 build-in-place functions (such as stream 'Input).
10467 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10468 formals for 'Constrained and accessibility level in the case of a
10469 predefined dispatching operation.
10471 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10472 point, no need to find the parent node.
10474 2007-08-16 Javier Miranda <miranda@adacore.com>
10476 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10477 and entry barriers.
10479 2007-08-16 Javier Miranda <miranda@adacore.com>
10481 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10482 is not really required and can introduce regression with the debugger.
10483 The original problem is fixed with the patch written for checks.adb.
10485 2007-08-16 Thomas Quinot <quinot@adacore.com>
10487 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10493 Including_Non_Switch set to False.
10494 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10495 Including_Non_Switch set to False.
10497 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10498 parameter Including_Non_Switch, defaulted to True. When
10499 Including_Non_Switch is False, options that are not switches and
10500 appear as relative path are not converted to absolute paths.
10502 2007-08-16 Nicolas Roche <roche@adacore.com>
10504 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

10515 from the immediate ancestor of Main_Unit_Entity.
10516 (Install_Limited_Withed_Unit): Do not install the limited view of
10517 package P if P is reachable through an ancestor chain from package C

10520 (Has_With_Clause): New routine.
10522 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10524 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10525 generic for an enclosing instance is a global reference, even though
10526 its scope is the enclosing instance.
10528 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10529 Javier Miranda <miranda@adacore.com>
10531 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
10532 initialize a limited object.
10533 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
10535 Make sure Has_Complex_Representation is inherited by derived type.
10537 2007-08-16 Robert Dewar <dewar@adacore.com>
10539 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
10542 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10544 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10545 implements an operation inherited from a progenitor interface, verify
10546 that they are subtype-conformant.

10549 Bob Duff <duff@adacore.com>
10550 Nicolas Setton <setton@adacore.com>
10552 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10553 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10554 the statement which is being resolved comes from a predefined library
10555 unit, all non-predefined library interpretations are skipped.
10556 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10557 but the "&" is user defined, give an error, because the folding would

10561 the parser has folded a long sequence of concatenations of string
10564 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10565 and "JMP_BUF" variables as artificial.
10566 (N_String_Literal): Do not use alloca for very long string literals. Use

10612 Ed Schonberg <schonberg@adacore.com>
10614 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10615 Suppress unmodified in-out parameter warning in some cases
10616 This patch is a also fairly significant change to the way suppressible
10617 checks are handled.
10619 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10620 needed for access to concurrent record types generated by the expander.
10621 (Generate_Range_Check): When generating a temporary to capture the
10622 value of a conversion that requires a range check, set the type of the
10623 temporary before rewriting the node, so that the type is always
10624 properly placed for back-end use.
10625 (Apply_Float_Conversion_Check): Handle case where the conversion is
10627 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10628 for a protected type in order to examine its discriminants.

10641 that has a specified Associated_Final_Chain, do not go up to the
10643 (Expand_N_Type_Conversion): Test for the case of renamings of access
10644 parameters when deciding whether to apply a run-time accessibility
10646 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10647 aggregate code before allocator, and ahead of declaration for
10648 temporary, to prevent access before elaboration when the allocator is
10649 an actual for an access parameter.
10650 (Expand_N_Type_Conversion): On an access type conversion involving an
10651 access parameter, do not apply an accessibility check when the
10652 operand's original node was an attribute other than 'Access. We now
10653 create access conversions for the expansion of 'Unchecked_Access and
10654 'Unrestricted_Access in certain cases and clearly accessibility should
10655 not be checked for those.
10657 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10658 includes a type conversion of a packed component that has been expanded,
10659 recover the original expression for the object, and use this expression
10660 in the post-call assignment statement, so that the assignment is made
10661 to the object and not to a back-end temporary.
10662 (Freeze_Subprogram): In case of primitives of tagged types not defined
10663 at the library level force generation of code to register the primitive
10664 in the dispatch table. In addition some code reorganization has been
10665 done to leave the implementation clear.
10666 (Expand_Call): When expanding an inherited implicit conversion,
10667 preserve the type of the inherited function after the intrinsic
10668 operation has been expanded.
10670 * exp_ch2.ads, exp_ch2.adb
10671 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10672 of an entry formal appearing in an assignment statement does not assign
10674 (Expand_Current_Value): Instead of calling a routine to determine
10675 whether the prefix of an attribute reference should be optimized or
10676 not, prevent the optimization of such prefixes all together.
10678 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10679 component whose prefix is known to be of an access type is an implicit
10680 dereference and does not assign to the prefix.

10683 Robert Dewar <dewar@adacore.com>
10685 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10686 itype is visited, make an entry into table to link associated node and
10688 Add comments and correct harmless error in Build_NCT_Hash_Tables

10690 the corresponding range construct, and not to the aggregate itself. to
10691 maintain a one-to-one correspondence between itype and its associated
10692 node, to prevent errors when complex expression is copied.
10693 Fix mishandling of multiple levels of parens
10695 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10696 treatment of limited views uniform for all visible declarations in a
10697 limited_withed package.
10698 (New_Copy_Tree): If hash table is being used and itype is visited,
10699 make an entry into table to link associated node and new itype.
10700 (Resolve_Record_Aggregate): Do not add an others box association for a
10701 discriminated record component that has only discriminants, when there
10702 is a box association for the component itself.
10704 * par-ch4.adb: Fix mishandling of multiple levels of parens
10706 2007-08-14 Robert Dewar <dewar@adacore.com>

10742 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
10743 to make treatment of limited views uniform for all visible declarations
10744 in a limited_withed package.
10745 Improve warnings for in out parameters
10746 (Set_Related_Interaface/Related_Interface): Allow the use of this

10752 generation of a freezing node to ensure proper management of null
10753 excluding access types in the backend.
10754 (Create_Extra_Formals): Test base type of the formal when checking for
10755 the need to add an extra accessibility-level formal. Pass the entity E
10756 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10757 originally being done in a couple of cases), to ensure that the
10758 Extra_Formals list gets set on the entity E when the first entity is
10760 (Conforming_Types): Add missing calls to Base_Type to the code that
10761 handles anonymous access types. This is required to handle the
10762 general case because Process_Formals builds internal subtype entities
10763 to handle null-excluding access types.
10764 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10765 functions that need it, even when not marked Requires_Overriding.
10766 Improve warnings for in out parameters

10768 Warn on return from procedure with unset out parameter
10769 Ensure consistent use of # in error messages
10770 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10771 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10772 the implicit conversion of the expression done for anonymous access
10773 types. This is required to generate the code of the null excluding
10774 check (if required).
10776 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10777 A formal parameter is never publicly referenceable outside of its body.
10778 (Check_References): For an unreferenced formal parameter in an accept
10779 statement, use the same warning circuitry as for subprogram formal
10781 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10782 Output_Unreferenced_Messages, containing the part of that routine that
10783 is now reused for entry formals as described above.
10784 (Goto_Spec_Entity): New function
10785 (Check_References): Do not give IN OUT warning for dispatching operation
10786 Improve warnings for in out parameters

10798 three forms of access attributes, using common code now for all three
10799 cases. Add a test for the case of applying an access attribute to
10800 an explicit dereference when the context is an access-to-interface
10801 type. In that case we need to apply the conversion to the prefix
10802 of the explicit dereference rather than the prefix of the attribute.
10803 (Attribute_Version, UET_Address): Set entity as internal to ensure
10804 proper dg output of implicit importation.
10805 (Expand_Access_To_Type): Removed.
10806 (Expand_N_Attribute_Reference): Merge the code from the three cases
10807 of access attributes, since the processing is largely identical for
10808 these cases. The substantive fix here is to process the case of a
10809 type name prefix (current instance case) before handling the case
10810 of interface prefixes.

10815 Robert Dewar <dewar@adacore.com>
10817 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10818 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10819 type that is an anonymous access to controlled object, establish
10820 an associated finalization chain to avoid corrupting the global
10821 finalization list when a dynamically allocated object designated
10822 by such a component is deallocated.
10823 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10824 functions that need it, even when not marked Requires_Overriding.
10825 (Initialize_Tag): Replace call to has_discriminants by call to
10826 Is_Variable_Size_Record in the circuitry that handles the

10835 (Build_Init_Procedure): Improve the generation of code to initialize the
10836 the tag components of secondary dispatch tables.
10837 (Init_Secondary_Tags): New implementation that simplifies the previous

10840 object declaration, for diagnostic purposes.
10841 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to

10845 Initialize or Normalize_Scalars is set.
10846 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10847 constructing the new profile, copy the null_exclusion indicator for each
10848 parameter, to ensure full conformance of the new body with the spec.

10851 Create wrappers for constructor functions that need it, even when not
10852 marked Requires_Overriding.
10853 (Covers): Handle properly designated types of anonymous access types,

10885 types declared in the declarative part of a nested package body or in
10886 the proper body of a stub.
10887 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10888 of the same dispatch table slot to renamed primitives.
10889 (Make_Select_Specific_Data_Table): Handle private types.

10891 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10892 output of implicit importation and exportation.
10893 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10894 first formal of the thunk is always associated with the controlling
10895 type. In addition perform the following code cleanup: remove formal
10896 Thunk_Alias which is no longer required, cleanup evaluation of the
10897 the controlling type, and update the documentation.
10898 Replace occurrence of Default_Prim_Op_Count by
10899 Max_Predef_Prims. Addition of compile-time check to verify
10900 that the value of Max_Predef_Prims is correct.
10901 (Check_Premature_Freezing): Apply check in Ada95 mode as well.

10903 object declaration, for diagnostic purposes.
10904 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10905 construction of statically allocated dispatch tables.
10906 (Make_DT): In case of library-level tagged types export the declaration

10910 (Make_Tags): New subprogram that generates the entities associated with
10911 the primary and secondary tags of Typ and fills the contents of Access_
10912 Disp_Table. In case of library-level tagged types imports the forward
10913 declaration of the primary tag that will be declared later by Make_DT.
10914 (Expand_Interface_Conversion): In case of access types to interfaces
10915 replace an itype declaration by an explicit type declaration to avoid

10919 Ed Schonberg <schonberg@adacore.com>
10920 Javier Miranda <miranda@adacore.com>
10922 * exp_util.ads, exp_util.adb:
10923 This patch replaces a number of occurrences of explicit tests for N_Null
10924 with calls to Known_Null. This improves tracking of null values, since
10925 Known_Null also catches null constants, and variables currently known to
10926 be null, so we get better tracking.
10927 (Ensure_Defined): create an itype reference only in the scope of the
10929 (Side_Effect_Free): A selected component of an access type that
10930 denotes a component with a rep clause must be treated as not
10931 side-effect free, because if it is part of a linked structure its
10932 value may be affected by a renaming.
10933 (Expand_Subtype_From_Expr): For limited objects initialized with build
10934 in place function calls, do nothing; otherwise we prematurely introduce
10935 an N_Reference node in the expression initializing the object, which
10936 breaks the circuitry that detects and adds the additional arguments to
10937 the called function. Bug found working in the new patch for statically
10938 allocated dispatch tables.
10939 (Is_Library_Level_Tagged_Type): New subprogram.
10940 (Remove_Side_Effects): If the expression of an elementary type is an
10941 operator treat as a function call.
10942 (Make_Literal_Range): If the index type of the array is not integer, use
10943 attributes properly to compute the constraint on the resulting aggregate
10946 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10947 class-wide type whose base type is an incomplete private type, leave
10948 class-wide type unfrozen so that freeze nodes can be generated
10949 properly at a later point.
10950 (Freeze_Entity, array case): Handle case of pragma Pack and component
10951 size attributre clause for same array.

11600 operations in Derive_Subprograms.
11601 (Collect_Previous_Instances): new procedure within of
11602 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11603 unit being loaded, to ensure that the generation of global symbols is

11606 takes progenitor types into account.
11607 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11608 traversing over the primitives of the formal and actual types to locate
11609 any abstract subprograms of the actual type that correspond to a
11610 nonabstract subprogram of the formal type's ancestor type(s), and issue
11611 an error if such is found.
11612 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11613 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11614 Remove bogus guard around calls to Inherit_Context.
11615 (Reset_Entity): If the entity is the selector of a selected component

11617 template only if the named number is global to the generic unit.
11618 (Set_Instance_Env): Only reset the compilation switches when compiling
11619 a predefined or internal unit.

11624 parameter to determine whether operation applies to the prefix.
11625 (Complete_Object_Operation): If actual has an access type and
11626 controlling formal is not an in_parameter, reject the actual if it is
11627 an access_to_constant type.
11628 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11629 type, the candidate operations are found in the scope of declaration of
11630 the type, because the type has no primitive subprograms.
11631 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11632 a private extension, only examine visible components before trying to
11633 analyze as a prefixed call.
11634 Change Entity_List to Type_To_Use, for better readability.
11635 (Has_Fixed_Op): Use base type when checking whether the type of an

11644 formal At_Any_Place indicating, when True, that we want to test for
11645 availability of the stream attribute at any place (as opposed to the
11646 current visibility context only).
11647 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11648 purpose of enforcing E.2.2(8) only if it is not available at any place.
11649 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11650 when checking the legality of an extension aggregate in a preelaborable
11651 package. Treat the literal null as a valid default expression in a
11652 component declaration for a type with preelaborable initialization.
11653 A limited interface is a legal progenitor for the designated type of a
11654 remote access to class-wide type.

11666 mark the full view as referenced, to prevent spurious warnings.
11667 (Find_Selected_Component, Has_Components): Handle properly non-limited
11668 views that are themselves incomplete types.
11669 Handle interfaces visible through limited-with clauses.
11670 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11671 subprogram generic actual for which we have generated a renaming.
11672 Warn when the renaming introduces a homonym of
11673 the renamed entity, and the renamed entity is directly visible.

11678 * sem_res.adb (Resolve_Allocator): Propagate any coextensions that
11679 appear in the subtree to the current allocator if it is not a static
11681 (Resolve_Allocator): Perform cleanup if resolution has determined that
11682 the allocator is not a coextension.
11683 (Resolve): Skip an interpretation hidden by an abstract operator only
11684 when the type of the interpretation matches that of the context.
11685 (Resolve): When looping through all possible interpretations of a node,
11686 do not consider those that are hidden by abstract operators.
11687 (Resolve_Actuals): When verifying that an access to class-wide object
11688 is an actual for a controlling formal, ignore anonymous access to
11689 subprograms whose return type is an access to class_wide type.
11690 (Resolve_Slice): If the prefix of the slice is a selected component
11691 whose type depends on discriminants, build its actual subtype before
11692 applying range checks on the bounds of the slice.
11693 (Valid_Conversion): In an instance or inlined body, compare root types,
11694 to prevent anomalies between private and public views.
11695 (Resolve): Improve error message for ambiguous fixed multiplication
11696 expressions that involve universal_fixed multiplying operations.

11701 * exp_ch9.adb (Build_Protected_Entry): Propagate the original source
11702 location to allow the correct generation of errors in case of

12847 an unconstrained array type, and the expression is a slice, use the
12848 bounds of the slice to construct the required constraint checks.
12849 Improve NOT NULL error messages
12850 (Apply_Constraint_Check): If the context is a null-excluding access
12851 type, diagnose properly the literal null.

12867 Arnaud Charlet <charlet@adacore.com>
12869 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12870 applicable to types that have the With_Type flag set. Returns the
12871 non-limited view of the type, if available, otherwise the type itself.
12872 For class-wide types, there is no direct link in the tree, so we have
12873 to retrieve the class-wide type of the non-limited view of the Etype.
12874 New attributes Static_Initialization and Static_Elaboration_Desired.
12875 Remove the pragma Thread_Body, and the associated flag
12876 Is_Thread_Body in entities, and all related code.

12889 (Original_Access_Type): Remove, not needed.
12890 (Root_Type): Handle properly subtypes of class-wide-types.
12893 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12894 class-wide types visible through limited-with clauses.
12895 (Try_Primitive_Operation): When examining all primitive operations of a
12896 tagged type, do not consider subprograms labeled as hidden unless they
12897 belong to a private generic type with a tagged parent.
12898 (Try_Object_Operation): Extensive rewriting, to handle properly various
12899 overloading cases, when several ancestors may have class-wide operations
12900 that are possible candidates, and when the overloaded functions return
12901 array types and have defaulted parameters so that the call may be
12902 interpreted as an indexing.
12903 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12904 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12905 successive actuals before analyzing the call itself.
12906 (Try_Primitive_Operation): A primitive operation is compatible with the
12907 prefix if the prefix has a synchronized type and the type of the formal
12908 is its corresponding record, as can be the case when the primitive
12909 operation is declared outside of the body of the type.
12910 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12911 perform homonym traversal, looking for class-wide operation matches
12912 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12913 access parameters are now restricted to anonymous access types.
12914 (Mark_Allocator): An allocator with a discriminant association parent is
12916 (Try_One_Prefix_Interpretation): If the type of the object is
12917 incomplete, as can be happen when it is a limited view obtained through
12918 a limited_with_clause, the selected component is not part of a prefixed
12920 (Complete_Object_Operation): Diagnose properly an object that is not
12921 aliased when the corresponding controlling formal is an access
12923 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12924 ambiguous calls in prefixed notation, where two primitives differ only
12925 in that the controlling argument of one is an access parameter.
12927 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12928 whether a function that returns an unconstrained type can be inlined.
12929 (Process_Formals): Diagnose properly the illegal use of an incomplete
12930 type in the profile of an access_to_subprogram declaration.
12931 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12932 operations are attached to the corresponding record.
12933 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12934 When processing a primitive of a concurrent type which implements an
12935 interface change the type of all controlling formals to that of the
12936 corresponding record type.
12937 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12938 to determine the tagged type to which a primitive belongs.
12939 (Check_Conventions): Capture condition to ignore a primitive operation
12940 (which is shared between the loop in Check_Conventions and the one in
12941 Check_Convention) in a new local function Skip_Check.
12942 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12943 confusion with Check_Conventions' own Prim_Op local variable.
12944 (Create_Extra_Formals): Test for a tagged result type rather than a
12945 controlling result when determining whether to add a BIP_Alloc_Form
12946 formal and a BIP_Final_List formal to the function.
12947 (Check_Conformance); For parameters that are anonymous access types,
12948 subtype conformance requires that the not null and the constant
12949 indicators must match
12950 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12951 to retrieve the appropriate type when processing a concurrent type
12952 declared within a generic. Minor comment reformatting. Change invocation
12953 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12955 (Analyze_Subprogram_Body): If the return type of a function is an
12956 anonymous access to the limited view of a class-wide type, and the
12957 non-limited view of the type is available, update the type of the
12958 function so that code can be generated.
12959 (Process_Formals): In case of access-subtype itype whose designated
12960 type is also an itype (situation that happens now with access to
12961 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12962 attribute to avoid backend problems.
12963 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12964 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12965 anonymous types' designated types are same before testing
12966 Subtypes_Statically_Match.
12967 (Create_Extra_Formals): Test for a named access parameter that is a
12968 controlling formal as an additional condition for adding an
12969 accessibility level formal. This can occur in the subp type created for
12970 dispatching calls in Expand_Dispatching_Call, and allows calling
12971 Create_Extra_Formals from that procedure rather than special-casing the
12972 extra formals there.
12973 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12974 when the function has a controlling result.
12975 (Check_Returns): Add much more knowledge of the optimization of local
12976 raise statements to gotos, to retain proper warnings in this case.
12977 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12978 nodes when looking for last statement.
12980 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12981 class-wide types visible through limited with clauses.
12982 (Add_One_Interp): If the operands are anonymous access types, the
12983 predefined operator on universal_access is immediately visibles
12984 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12985 other anonymous access types.
12986 (Disambiguate): Take into account CIL convention.
12987 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12989 2007-06-06 Robert Dewar <dewar@adacore.com>
12991 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
12992 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
12993 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
12994 Fix lower bound of tables.
12997 * nlists.adb: Ditto.
12998 (Prev_Node, Next_Node): Change index type to Int so that it properly
12999 covers the range First_Node_Id - 1 up.
13001 2007-06-06 Javier Miranda <miranda@adacore.com>
13002 Ed Schonberg <schonberg@adacore.com>
13003 Bob Duff <duff@adacore.com>
13004 Hristian Kirtchev <kirtchev@adacore.com>
13006 * exp_aggr.ads, exp_aggr.adb:
13007 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13008 in extension aggregates.
13009 (Flatten): Other conditions being met, an aggregate is static if the
13010 low bound given by component associations is different from the low
13011 bound of the base index type.
13012 (Packed_Array_Aggregate_Handled): If the component type is itself a
13013 packed array or record, the front-end must expand into assignments.
13014 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13015 Init_Pr, instead of Ancestor_Is_Expression.
13016 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13017 coextension chain root, either generate a list controller or use the
13018 already existing one.
13019 (Static_Array_Aggregate): New procedure to construct a positional
13020 aggregate that can be handled by the backend, when all bounds and
13021 components are compile-time known constants.
13022 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13023 types covering interface types into assignments.
13024 (Replace_Type): move to Build_Record_Aggr_Code.
13025 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13026 interface type, convert to the definite type of the aggregate itself,
13027 so that needed components are visible.
13028 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13029 components and the context is an extended return statement do not
13030 create a transient block for it, to prevent premature finalization
13031 before the return is executed.
13032 (Gen_Assign): Do not generate a call to deep adjust routine if the
13033 component type is itself an array of controlled (sub)-components
13034 initialized with an inner aggregate.
13035 (Component_Check): New name for Static_Check. This name is now more
13036 appropriate, and documentation is added which was missing.
13037 (Component_Check): Add test for bit aligned component value
13038 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13039 Tagged_Comps, name is more appropriate given added function below.
13040 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

13043 Javier Miranda <miranda@adacore.com>
13044 Robert Dewar <dewar@adacore.com>
13046 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13047 Terminated: Add unchecked type conversion from System.Address to
13048 System.Tasking.Task_Id when calling the predefined primitive
13050 Disable new Ada 05 accessibility check for JVM.NET targets, which
13051 cannot be implemented in a practical way.
13052 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13053 the sources always references the tag of the actual object. Therefore,
13054 if 'Tag is applied in the sources to class-wide interface objects we
13055 generate code that displaces "this" to reference the base of the object.
13056 (Expand_N_Attribute_Reference, case Size): Return specified size if
13057 known to front end.
13058 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13059 has code that displaces the pointer of the object to manage interface
13060 types. However this code must not be executed when the prefix is a
13061 subprogram. This bug caused the wrong expansion of the internally
13062 generated assignment that fills the dispatch table when the primitive
13063 is a function returning a class-wide interface type.
13064 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13065 Set_Attribute_Name for Name_Unaligned_Valid.
13067 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13068 Gary Dismukes <dismukes@adacore.com>
13070 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13071 If the initialization is the equivalent aggregate of the initialization
13072 procedure of the type, do not remove it.
13073 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13074 initialized to null from having their expression reset to empty and
13075 note this exception in the comment.

13079 Ed Schonberg <schonberg@adacore.com>
13080 Gary Dismukes <dismukes@adacore.com>
13082 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13083 Add "with" and "use" clauses for Sem_Attr.
13084 (Expand_Current_Value): Do not replace occurences of attribute
13085 references where the prefix must be a simple name.
13087 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13088 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13089 Attribute_Requires_Simple_Name_Prefix.
13090 (Name_Modifies_Prefix): Body of new function.
13091 (Requires_Simple_Name_Prefix): Body of new function.
13092 (Resolve_Attribute, case Access): Improve error message for case of
13093 mismatched conventions.
13094 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13096 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13097 constrained subtype for a nominal unconstrained type, use its base type
13098 to check for conformance with the context.
13099 (Resolve_Attribute): Remove test of the access type being associated
13100 with a return statement from condition for performing accessibility
13101 checks on access attributes, since this case is now captured by
13102 Is_Local_Anonymous_Access.
13103 (Analyze_Access_Attribute): Set Address_Taken on entity
13104 (Analyze_Attribute, case Address): Set Address_Taken on entity
13105 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13106 validating an access attribute whose prefix is a current instance.
13107 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13108 applied to dispatching operations, if freezing is required then we set
13109 the attribute Has_Delayed_Freeze in the prefix's entity.
13110 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13111 current scope if access of local subprogram taken
13112 (Analyze_Access_Attribute): Check legality of self-reference even if the
13113 expression comes from source, as when a single component association in
13114 an aggregate has a box association.
13115 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13116 the prefix if it is a protected operation and the attribute is
13117 Unrestricted_Access.
13118 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13119 reference to the base type of the context, to force a constraint check
13120 when the context is an access subtype with an explicit constraint.
13121 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13122 node is rewritten as an interface conversion. leave unanalyzed after
13123 resolution, to ensure that type checking against the context will take

13127 Javier Miranda <miranda@adacore.com>
13128 Robert Dewar <dewar@adacore.com>
13130 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13131 wrapper when the full view of the controlling type of an inherited
13132 function that dispatches on result implements interfaces.
13133 (Expand_N_Object_Declaration): In cases where the type of the
13134 declaration is anonymous access, create finalization list for it.
13135 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13136 if the object has no explicit initialization, to match description of
13137 functionality of pragam Persistent_BSS.
13138 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13139 new function to build static aggregates, to replace initialization call
13140 when static initialization is desired.
13141 (Freeze_Type): Generate a list controller for an access type whenever
13142 its designated type has controlled anonymous access discriminants.
13143 (Build_Equivalent_Aggregate): New procedure to compute a static
13144 aggregate to be used as default initialization for composite types,
13145 instead of a generating a call to the initialization procedure for the
13147 (Build_Initialization_Call): When available, replace a call to the
13148 initialization procedure with a copy of the equivalent static aggregate
13150 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13151 declarations for objects of a class-wide interface type, rather than
13152 just identifiers, to prevent visibility problems.
13153 (Expand_N_Object_Declaration): When expanding the declaration for an
13154 object of a class-wide interface type, preserve the homonym chain of
13155 the original entity before exchanging it with that of the generated
13156 renaming declaration.
13157 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13158 active, because there is no way to handle the exception.
13159 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13160 to do a minimum decoration of the Access_Disp_Table list.
13161 (Expand_Record_Controller): Avoid the addition of the controller between
13162 the component containing the tag of a secondary dispatch table and its
13163 adjacent component that stores the offset to the base of the object.
13164 This latter component is only generated when the parent type has
13165 discriminants ---documented in Add_Interface_Tag_Components).
13166 (Apply_Array_Size_Check): Removed, no longer needed.
13167 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13168 components, create a Master_Entity for it only if it contains tasks.
13169 (Build_Init_Procedure): Suppress the tag assignment compiling under
13171 (Freeze_Record_Type): Remove code associated with creation of dispatch
13173 (Init_Secondary_Tags): Update type of actuals when generating calls to
13174 Ada.Tags.Set_Offset_To_Top
13175 (Stream_Operation_OK): Disable use of streams compiling under no
13177 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13178 if Has_Init_Expression set.
13179 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13180 Register_Primitive, which provides the same functionality.
13181 (Requires_Init_Proc): Return false in case of interface types.
13182 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13184 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13185 is always associated with a predefined primitive because the internal
13186 entities associated with interface types are not predefined primitives.
13187 Therefore, the call to Is_Internal is replaced by a call to the
13188 function Is_Predefined_Dispatching_Operation.
13189 (Make_Eq_If): When generating the list of comparisons for the
13190 components of a given variant, omit the controller component that is
13191 present if the variant has controlled components.
13193 2007-06-06 Javier Miranda <miranda@adacore.com>
13194 Hristian Kirtchev <kirtchev@adacore.com>
13195 Bob Duff <duff@adacore.com>
13197 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13198 handle the creation of finalization lists and calls for nested
13199 coextensions when the root of the chains is part of a return statement.
13200 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13202 (Expand_Record_Equality): Skip components that are interface types.
13203 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13204 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13205 with Rewrite_Coextension. Change the condition for detecting coextension
13207 (Is_Local_Access_Discriminant): Removed.
13208 (Rewrite_Coextension): New routine which rewrites a static coextension
13209 as a temporary and uses its unrestricted access in the construction of
13211 (Complete_Coextension_Finalization): New routine. Generate finalization
13212 attachment calls to all delayed coextensions.
13213 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13214 the allocator is not a coextension itself and has delayed coextensions.
13215 If the current allocator is controlled, but also a coextension, delay
13216 the generation of the finalization attachment call.
13217 Rename local variable "Node" to "Nod" in order to avoid confusion with
13219 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13220 limited types that are not inherently limited. Such an allocator is
13221 illegal, but is generated by the expander for a return statement, to
13222 copy the result onto the secondary stack. This is the only case where a
13223 limited object can be copied. Generate code to displace the pointer
13224 to the object if the qualified expression is a class-wide interface
13225 object. Such displacement was missing and hence the copy of the object
13227 (Apply_Accessibility_Check): Handle allocated objects initialized in
13229 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13230 and Expand_Allocator_Expression. Allocating class-wide interface objects
13231 this routine displaces the pointer to the allocated object to reference
13232 the component referencing the corresponding secondary dispatch table.
13233 Expand_Allocator_Expression): Add missing support to allocate class-wide
13234 interface objects initialized with a qualified expression.
13235 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13236 function result type, and use the finalization list associated with the
13237 function scope in that case (such an anonymous type should not be
13238 treated like an access parameter's type).
13240 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13241 Gary Dismukes <dismukes@adacore.com>
13242 Javier Miranda <miranda@adacore.com>
13244 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13245 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13246 required exception handler.
13247 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13248 properly the case of a function whose return type is a limited
13249 class-wide interface type. Modify the code of the accessibility
13250 check to handle class-wide interface objects. In this case we need to
13251 displace "this" to reference the primary dispatch table to get access
13252 to the TSD of the object (to evaluate its accessibility level).
13253 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13254 rather than a controlling result as one of the conditions for
13255 generating tests of the implicit BIP_Alloc_Form formal. The
13256 initialization assignment is also handled according to whether the
13257 result is tagged instead of controlling.
13258 In the case where the init assignment is inserted in the "then" part of
13259 the allocation conditional, rewrite the target to be a dereference of
13260 the implicit BIP_Object_Access formal.
13261 If the returned value is unconstrained and created on the secondary
13262 stack, mark the enclosing block and function so that the secondary
13263 stack is not reclaimed on return.
13264 Treat returns from functions with controlling results similarly to
13265 returns from functions with unconstrained result subtypes.
13266 If the object returned is unconstrained, and an allocator must be
13267 created for it, analyze the allocator once the block for the extended
13268 return is installed, to ensure that finalizable components
13269 of the expression use the proper finalization list. Guard the call to
13270 Move_Final_List with a check that there is something to finalize.
13271 (Make_Tag_Ctrl_Assignment): Use "old" handling
13272 of controlled type assignment for virtual machines, since new code uses
13273 unsupported features (such as direct access to bytes in memory).
13275 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13276 Ed Schonberg <schonberg@adacore.com>
13278 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13279 accessibility actual, check for the case of an aliased object that has
13280 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13281 we fall into processing for the attribute rather than the name of the
13283 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13284 formal has its address taken in the body, create a temporary to capture
13285 value. If the return type is a limited interface, do not treat the
13286 return value as Controlled.
13287 (Is_In_Place_Function): If the return type is a limited interface,
13288 treat as returning in place. The actual returned object may not always
13289 be limited, but the caller has to assume that it is returned in place.
13290 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13291 context of an allocator, use the correct finalization chain (that is,
13292 the chain belonging to the access type, rather than the chain belonging
13293 to the current scope).
13294 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13295 result type rather than a controlling result as a precondition for
13296 adding an allocation form actual to a build-in-place call.
13297 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13298 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13299 primitive in the dispatch tables. This work is now done by Make_DT when
13300 the type is frozen.
13301 (Register_Predefined_DT_Entry): Removed.
13302 (Add_Return): If end label is not present, use sloc of last statement
13303 for generated return statement in procedure, for better gdb behavior
13305 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13306 object address nodes to ensure proper processing by routines like
13308 (Expand_Call): Fix generation of validity check for parameter
13309 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13310 the allocation form parameter if the result subtype is constrained,
13311 except when the function has a controlling result.
13312 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13313 rather than Is_Controlled and Has_Controlled_Component, since we want to
13314 include class-wide result types in this treatment. Also test for a
13315 controlling result, since that also requires passing a finalization
13317 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13318 even when the result subtype is constrained, to handle calls involving
13319 controlling results.
13320 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13321 is now called even when the result subtype is constrained, to handle
13322 calls involving controlling results.
13323 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13324 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13325 now performs the test).
13326 (Make_Build_In_Place_Call_In_Object_Declaration):
13327 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13328 constrained, to handle calls involving controlling results.
13329 (Add_Return): Accomodate rewritten pattern from local raise to goto
13330 transformation, so that we still recognize an transfer statement
13331 and do the right thing here in that case.
13332 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13333 and end of subprogram code.
13334 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13335 support for primitives that are functions (without formals) with a
13336 controlling result.
13337 (Inherited_From_Formal): If the actual subtype has not generic parent
13338 type, it is not an actual for a formal derived type, and there is no
13339 operation to inherit from the formal.
13341 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13342 Thomas Quinot <quinot@adacore.com>
13344 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13345 inserted cleanup code appropriately for GDB use.
13346 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13347 exception handler for Deep_Adjust or Deep_Finalize.
13348 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13349 Raise_From_Controlled_Operation is available, use a call to that
13350 subprogram instead of a plain "raise Program_Error" node to raise
13351 Program_Error if an exception is propagated from an Adjust or Finalize
13353 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13354 appears in the optional statement list of a triggering alternative, the
13355 scope actions can be inserted directly there, and not in the list that
13356 includes the asynchronous select itself.
13358 2007-06-06 Ed Schonberg <schonberg@adacore.com>

13360 Hristian Kirtchev <kirtchev@adacore.com>
13362 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13363 generated exception handler appropriately when debugging generated code.
13364 Deal properly with No_Exception_Propagation restriction mode.
13365 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13366 System.Address to System.Tasking.Task_Id when processing the result of
13367 the predefined primitive _disp_get_task_id.
13368 (Expand_N_Asynchronous_Select): Clarify comment.
13369 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13370 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13371 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13372 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13373 privals and for generated call to Complete_Entry_Body, for better gdb
13375 (Copy_Result_Type): Utility to construct a parameter and result profile
13376 for protected functions whose return type is an anonymous access to
13378 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13380 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13381 point when the local-raise-to-goto transformation has taken place.
13383 2007-06-06 Javier Miranda <miranda@adacore.com>
13384 Nicolas Setton <setton@adacore.com>
13386 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13387 functionality when the backend is generating code.
13388 Otherwise any serious error
13389 reported by the backend calling the frontend routine Error_Msg
13390 changes the Compilation_Mode to Check_Semantics, disables the
13391 functionality of this routine and causes the generation of
13392 spureous additional errors.
13394 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13395 debugging information now generated by the compiler for fat-pointer
13397 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13399 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13401 2007-06-06 Thomas Quinot <quinot@adacore.com>
13403 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13404 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13405 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13406 For a remote call to a function with a classwide return type, apply an
13407 E.4(18) check to the returned value.
13408 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13409 stream attributes of the designated type of an RACW, as they are not
13410 dispatching primitive operations.
13412 2007-06-06 Geert Bosch <bosch@adacore.com>

13532 subtype from the function call, as is done for private types.
13533 (Side_Effect_Free): An expression that is the renaming of an object or
13534 whose prefix is the renaming of a object, is not side-effect free

14059 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
14060 associated with dispatch tables is known at compile time.
14061 (Get_Value): If an association in a record aggregate has a box
14062 association, and the corresponding record component has a default
14063 expression, always copy the default expression, even when the

15244 associated with either the Equivalent or Root type, instead of the
15246 (gnat_to_gnu_entity): Manually mark the top of the DECL_FIELD_OFFSET
15247 subtree for every field of a global record type.
15248 (gnat_to_gnu_entity) <E_Record_Subtype>: If the subtype has

15265 (E_Return_Statement): This node type has the Finalization_Chain_Entity
15266 attribute, in case the result type has controlled parts.
15267 (Requires_Overriding): Add this new flag, because "requires
15268 overriding" is subtly different from "is abstract" (see AI-228).
15269 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
15270 Is_Abstract_Type. Make sure these are called only when appropriate.

15332 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
15333 "abstract subprograms must be visible" message, whether or not the type
15334 is an interface; that is, remove the special case for interface types.
15335 (Analyze_Function_Return): Remove error message "return of task objects

15360 build-in-place functions with result type with controlled parts.
15361 Remove no longer used entities.
15363 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
15364 longer needed, because the full type is now limited, and therefore a

15397 to handle properly the anonymous access case.
15399 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
15400 for all access attributes, because overload resolution should work the
15401 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This

15411 attempt to derive from a synchronized tagged type.
15412 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
15413 type, inherit the class-wide type already created, because it may
15414 already have been used in a self-referential anonymous access component.
15415 (Mentions_T): Recognize self-referential anonymous access components
15416 that use (a subtype of) the class-wide type of the enclosing type.
15417 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15418 Derived_Type for Prev formal on call to
15419 Check_Anonymous_Access_Components rather than Empty.
15420 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15421 a record extension in deciding whether to create a class-wide type,

15438 with abstract interfaces.
15439 (Analyze_Subtype_Indication): Resolve the range with the given subtype
15440 mark, rather than delaying the full resolution depending on context.

15467 (Compile_Sources): Do nothing, not even check if the source is up to
15468 date, if its project is externally built.
15469 (Compile): When compiling a predefined source, add -gnatpg
15470 as the second switch, after -c.
15471 (Compile_Sources): Allow compilation of Annex J renames without -a
15472 (Is_In_Object_Directory): Check if the ALI file is in the object
15473 even if there is no project extension.

15475 gnatbind if the ALI file effectively exists.
15476 (Initialize): Add the directory where gnatmake is invoked in front of
15477 the path if it is invoked from a bin directory, even without directory

15498 renamings Calendar, Machine_Code, Unchecked_Conversion and
15499 Unchecked_Deallocation only when Renamings_Included is True.
15501 * par.adb: Allow library units Calendar, Machine_Code,
15502 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15503 when -gnatg is not specified.
15504 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15505 there is no need to generate always a record_definition_node in case
15506 of synchronized interface types.
15507 (SIS_Entry_Active): Initialize global variable to False
15508 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

15533 (Convert_Aggr_In_Allocator): If the allocator is for an access
15534 discriminant and the type is controlled. do not place on a finalization
15535 list at this point. The proper list will be determined from the

15538 initialize record controller if needed, before the components, to ensure
15539 that they are properly finalized.

15554 succeed in that case, even when the expression originates from a
15555 parameter of the containing subprogram.
15556 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15557 under No_Dispatching_Calls restriction. During the semantic analysis
15558 we already notified such violation.
15559 (Tagged_Membership): Constant folding. There is no need to check
15560 the tag at run-time if the type of the right operand is non
15561 class-wide abstract.

15576 initialize most the TSD components by means of an aggregate.
15577 Modify the declaration of the object containing the TSD
15578 because we now expand code that has a higher level of abstraction.
15579 The TSD has a discriminant containing the Inheritance Depth Level,
15580 value that is used in the membership test but also to fix the size
15581 of the table of ancestors.
15582 (Expand_Interface_Conversion): Insert function body at the closest place
15583 to the conversion expression, to prevent access-before-elaboration

15634 First/Next_Component_Or_Discriminant
15635 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
15636 (Find_Implemented_Interface): Removed. All the calls to this subprogram

15640 support concurrent types implementing interfaces.
15641 (Find_Implemented_Interface): Removed. All the calls to this subprogram

15645 CW_Or_Controlled_Type whenever the issue is related to
15646 using or not the secondary stack.

15658 Bob Duff <duff@adacore.com>
15659 Cyrille Comar <comar@adacore.com>
15661 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
15662 anonymous, use finalization list of enclosing dynamic scope.
15663 (Expand_N_Package_Declaration): For a library package declaration
15664 without a corresponding body, generate RACW subprogram bodies in the
15665 spec (just as we do for the task activation call).
15666 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15667 Is_Abstract_Type. Make sure these are called only when appropriate.
15668 Remove all code for DSP option
15669 (CW_Or_Controlled_Type): new subprogram.
15671 2007-04-06 Eric Botcazou <botcazou@adacore.com>
15672 Ed Schonberg <schonberg@adacore.com>
15673 Gary Dismukes <dismukes@adacore.com>
15675 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15676 parameter. If it is set to true, return a result capped according to
15677 the global upper bound for the index of an entry family.
15678 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
15679 (Build_Find_Body_Index): Adjust for above change.
15680 (Entry_Index_Expression): Likewise.
15681 (Is_Potentially_Large_Family): New function extracted from...
15682 (Collect_Entry_Families): ...here. Call it to detect whether the family
15683 is potentially large.
15684 (Build_Entry_Count_Expression): If the family is potentially large, call
15685 Family_Size with 'Cap' set to true.
15686 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15687 a protected version of an operation declared in the private part of
15688 a protected object, because they may be invoked through a callback.
15689 (Set_Privals): If the type of a private component is an anonymous access
15690 type, do not create a new itype for each protected body.
15691 If the body of a protected operation creates
15692 controlled types (including allocators for class-widetypes), the
15693 body of the corresponding protected subprogram must include a
15695 (Build_Activation_Chain_Entity): Build the chain entity for extended
15697 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15698 to determine whether operation overrides an inherited primitive.
15699 (Build_Wrapper_Spec): Add code to examine the parents while looking
15700 for a possible overriding candidate.
15701 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15702 hold an actual parameter value since its initialization is separated
15703 from the the declaration. Prevents errors on null-excluding access
15706 2007-04-06 Thomas Quinot <quinot@adacore.com>
15707 Pablo Oliveira <oliveira@adacore.com>
15709 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15710 Do an Unchecked_Conversion to handle the passage from the Underlying
15711 Type to the Base Type when calling Build_To_Any_Call and
15712 Build_From_Any_Call.
15713 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15714 E_Constant, depending upon Variable formal.
15715 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15716 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15717 parameter that requires an extra constrained parameter, declare
15718 temporary for actual as a variable, not a constant.
15719 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15720 the unit being compiled is the one that contains the stub type.
15721 Change primitive operation name for the RACW associated with a RAS
15722 from Call to _Call so it cannot clash with any legal identifier.
15723 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15725 (Append_RACW_Bodies): New subprogram.
15726 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15727 Add_Receiving_Stubs_To_Declarations functions.
15728 When expanding a package body, this list correspond to the
15729 statements in the HSS at the end of the pacakge.
15730 When expanding a package spec, this list correspond to the
15732 (Add_Receiving_Stubs_To_Declarations): Append the function
15733 registering the receiving stubs at the end of the 'Stmts' list.
15734 (RCI_Package_Locator): Pass the new Version generic formal when
15735 instantiating a RCI_Locator package.
15736 (Build_From_Any_Function): To compute the High bound for an
15737 unconstrained array actual, we add the Low bound with the length.
15738 Thus we must convert the low bound and the length to an appropriate
15739 type before doing the sum.
15740 (Build_Subprogram_Receiving_Stubs, PolyORB):
15741 * Retrieve the extra formals parameters at the
15742 end of the parameter stream.
15743 * Use Move_Any_Value to write back out parameters
15744 after executing the request as it is more efficient
15745 than Copy_Any_Value.
15746 * Build the any containing Extra Formals with the
15747 appropriate typecode.
15748 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15749 empty Component_List.
15750 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15751 the tree the declaration for an object that serves as actual parameter
15752 in server-side stubs.
15753 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15754 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
15755 Use Build_Actual_Object_Declaration to prepare the actuals.

15757 Extra Constrained Parameters.
15758 (Build_General_Calling_Stubs): Set the parameter type to boolean for
15759 Extra Constrained parameters.
15760 (Build_To_Any_Function, Build_From_Any_Function,
15761 Built_TypeCode_Function): When Typ is implicit, call the correct
15762 function with the first not implicit parent type.
15763 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15764 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15765 typecode from the Etype. Therefore we retrieve the correct typecode
15766 with a call to Get_Any_Type.
15767 (Copy_Specification): Do controlling formal type substitution based on
15768 Is_Controlling_Formal flag, instead of caller-provided object type.
15769 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15770 a RACW primitive operation, we might get a subprogram declaration for an
15771 ancestor of the RACW designated type (not for the designated type
15772 itself), in the case where this operation is inherited. In this case we
15773 have no easy means of determining the original tagged type for which
15774 the primitive was declared, so instead we now rely on
15775 Copy_Specification to use the Is_Controlling_Formal flag to determine
15776 which formals require type substitution.

15782 GNAT.Current_Exception are not allowed if pragma Restrictions
15783 (No_Exception_Propagation) is set and in any case make the associated
15784 handler unsuitable as a target for a local raise statement.
15785 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15786 run-time subprogram CW_Membership by call to Build_CW_Membership.
15787 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15788 by a function call, a temporary must be created before expanding the
15789 Constructor_Call itself, to prevent out-of-order elaboration in the
15790 back-end when stack checking is enabled..
15792 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15794 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15795 result are the bounds of the left operand, not the right.
15797 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15800 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use
15801 discriminant defaults.

15812 box corresponds to a component of the type.
15813 (Resolve_Record_Aggregate): Split Is_Abstract flag into
15814 Is_Abstract_Subprogram and Is_Abstract_Type.

15868 the .ci files belonging to the projects, including binder generated
15870 (Non_VMS_Usage): Document that gnatstack accept project file switches.
15871 (GNATCmd): Update the B_Start variable if we are in a VMS environment.

15917 * mingw32.h (S2WSU): New macro to convert from a string to a
15918 wide-string using the UTF-8 encoding. The S2WS macro supports now only
15919 standard 8bits encoding.
15920 (WS2SU): As above but converting from wide-sring to string.
15921 This is needed as it is necessary to have access to both versions in the
15922 runtime for the form parameter encoding support.
15923 This set of patch add support for the encoding form parameter.
15924 (S2WS): Improve implementation to handle cases where the filename is not
15925 UTF-8 encoded. In this case we default to using the current code page
15926 for the conversion.
15928 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
15929 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

15973 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
15974 __gnat_adjust_context_for_raise.
15975 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
15976 implementation of floating point operations as native x86 targets.
15977 So the FPU should be initialized in the same way using finit. Fix
15978 floating point operations accuracy issues.
15979 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
15980 member in struct sigaction, so as to avoid warning for incompatible

15996 Javier Miranda <miranda@adacore.com>
15998 * lib-xref.ads, lib-xref.adb:
15999 Modify the loop that collects type references, to include interface
16000 types that the type implements. List each of these interfaces when
16001 building the entry for the type.
16002 (Generate_Definition): Initialize component Def and Typ of new entry
16003 in table Xrefs, to avoid to have these components unitialized.

16047 2007-04-06 Robert Dewar <dewar@adacore.com>
16049 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16050 it no longer destroys the contents of Name_Buffer or Name_Len and
16051 non-standard and invalid names are handled better.

16066 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16067 illegal in Ada 95, in cases where it is legal. Change the warnings to
16068 errors in other cases. Don't give the error unless the "not null"
16069 parses properly. Correct the source position at which the error occurs.
16070 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16071 P_Null_Exclusion, to suppress "not null" warnings.

16147 the default project path, initially done during elaboration of the
16149 If the prefix returned by Sdefault is null, get the prefix from a call
16150 to Executable_Prefix_Path.
16151 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16154 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16155 canonical directory name to open the directory from which files are
16157 (Record_Other_Sources): Idem.
16158 (Locate_Directory): Add the possibility to create automatically missing
16159 directories when Setup_Projects is True.
16160 Call Locate_Directory so that the directory will be created when
16161 Setup_Projects is True, for object dir, library dir, library ALI dir,
16162 library source copy dir and exec dir.
16164 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16167 2007-04-06 Robert Dewar <dewar@adacore.com>

16182 Next_Component_Or_Discriminant.
16184 * style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
16187 * stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch

16202 full word is no longer compared twice.
16204 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16206 * sem_ch10.adb (Install_Limited_Context_Clauses.
16207 Expand_Limited_With_Clause): Use a new copy of selector name in the
16208 call to Make_With_Clause. This fixes the tree structure for ASIS
16209 purposes. Nothing is changed in the compiler behaviour.
16210 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16211 a package renaming.
16212 (Install_Limited_With_Clauses): Do not install non-limited view when it
16213 is still incomplete.
16215 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16216 Gary Dismukes <dismukes@adacore.com>
16218 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16219 when capturing size information, instead of base type, which for a
16220 formal array type will be the unconstrained type.
16221 (Analyze_Formal_Object_Declaration): Add check for illegal default
16222 expressions for a formal in object of a limited type.
16223 (Instantiate_Object): Ditto.
16224 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16225 because they were defaulted in the formal package and no check applies
16227 (Check_Formal_Package_Instance): Extend conformance check to other
16228 discrete types beyond Integer.
16229 (Process_Default): Copy directly the unmatched formal. A generic copy
16230 has already been performed in Analyze_Formal_Package.
16231 (Analyze_Associations): If a formal subprogram has no match, check for
16232 partial parametrization before looking for a default, to prevent
16234 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16235 not set the instantiation environment before analyzing the actuals.
16236 Fixes regression on 8515-003 with implementation of AI-133.
16237 Set_Instance_Env checks whether the generic unit is a predefined
16238 unit, in which case the instance must be analyzed with the latest Ada
16239 mode. This setting must take place after analysis of the actuals,
16240 because the actuals must be analyzed and frozen in the Ada mode extant
16241 outside of the current instantiation.
16242 (Save_Env, Restore_Env): Preserve and restore the configuration
16243 parameters so that predefined units can be compiled in the proper Ada
16245 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16246 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16247 and Is_Abstract_Type.
16248 (Analyze_Formal_Package): For better error recovery, Add exception
16249 handler to catch Instantion_Error, which can be raised in
16250 Analyze_Associations

16253 Bob Duff <duff@adacore.com>
16254 Gary Dismukes <dismukes@adacore.com>
16256 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16257 prefix type is a discriminated subtype of the type of the formal.
16258 (Analyze_Allocator): Collect all coextensions regardless of the context.
16259 Whether they can be allocated statically is determined in exp_ch4.
16260 (Analyze_Selected_Component): If the prefix is a limited view and the
16261 non-limited view is available, use the non-limited one.
16262 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16263 therefore illegal), suggest a qualified expression rather than a type
16264 conversion, because a type conversion would be illegal in this context.
16265 (Anayze_Allocator): Trace recursively all nested allocators so that all
16266 coextensions are on the corresponding list for the root. Do no mark
16267 coextensions if the root allocator is within a declaration for a stack-
16268 allocated object, because the access discriminants will be allocated on
16270 (Analyze_Call): Remove restriction on calls to limited functions for the
16271 cases of generic actuals for formal objects, defaults for formal objects
16272 and defaults for record components.
16273 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16274 element list. Their expansion is delayed until the enclosing allocator
16275 is processed and its finalization list constructed.
16276 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16277 for an operation with the given name among the primitive operations of
16278 the corresponding record type.
16279 (Analyze_Selected_Component): If the prefix is a task type that
16280 implements an interface, and there is no entry with the given name,
16281 check whether there is another primitive operation (e.g. a function)
16283 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16284 properly the indexing of a function call written in prefix form, where
16285 the function returns an array type, and all parameters of the function
16286 except the first have defaults.
16287 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16288 the original operands, rather than relocating them, for efficiency and
16289 to work properly when an operand is overloaded.
16290 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16291 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16292 (Analyze_Selected_Component): If the prefix is a private extension, only
16293 scan the visible components, not those of the full view.
16294 (Try_Primitive_Operation): If the operation is a procedure, collect all
16295 possible interpretations, as for a function, because in the presence of
16296 classwide parameters several primitive operations of the type can match
16297 the given arguments.
16299 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16300 Robert Dewar <dewar@adacore.com>
16302 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16303 tag-indeterminate call to an abstract function, when the left-hand side
16305 (Analyze_Loop_Statement): Improve detection of infinite loops
16307 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16308 Thomas Quinot <quinot@adacore.com>
16310 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16311 out of Analyze_Package_Declaration, because processing must be applied
16312 to package bodies as well, for deferred constants completed by pragmas.
16313 (Analyze_Package_Declaration): When the package declaration being
16314 analyzed does not require an explicit body, call Check_Completion.
16315 (May_Need_Implicit_Body): An implicit body is required when a package
16316 spec contains the declaration of a remote access-to-classwide type.
16317 (Analyze_Package_Body): If the package contains RACWs, append the
16318 pending subprogram bodies generated by exp_dist at the end of the body.
16319 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16320 Is_Abstract_Subprogram and Is_Abstract_Type.
16321 (Preserve_Full_Attributes): The full entity list is not an attribute
16322 that must be preserved from full to partial view.
16324 * sem_dist.adb (Add_RAS_Dereference_TSS):
16325 Change primitive name to _Call so it cannot clash with any legal
16326 identifier, and be special-cased in Check_Completion.
16327 Mark the full view of the designated type for the RACW associated with
16328 a RAS as Comes_From_Source to get proper view switching when installing
16329 private declarations.
16330 Provite a placeholder nested package body along with the nested spec
16331 to have a place for Append_RACW_Bodies to generate the calling stubs
16332 and stream attributes.
16334 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16335 Robert Dewar <dewar@adacore.com>
16337 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16338 that is a limited view, check the non-limited view if available.
16339 (Undefined): Refine error message for missing with of Text_IO
16340 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16341 to distinguish real missing with cases.
16342 Fix format of all missing with messages
16343 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16344 renaming as body when renamed entity is abstract.
16346 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16347 Javier Miranda <miranda@adacore.com>
16349 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make

16359 Javier Miranda <miranda@adacore.com>
16361 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16362 dereference of a local object R created as a reference to another
16363 object O, use the access level of O.
16364 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16365 rather than local Same_Formal_Type, to check whether protected operation
16366 overrides an inherited one.
16367 (Same_Formal_Type): New predicate, used when matching signatures of
16368 overriding synchronized operations, to handle the case when a formal
16369 has a type that is a generic actual.
16370 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16371 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16372 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16373 syntactic ambiguities involving indexing of function calls that return
16375 (Abstract_Interface_List): New subprogram that returns the list of
16376 abstract interfaces associated with a concurrent type or a
16377 concurrent record type.
16378 (Interface_Present_In_Parent): New subprogram used to check if a
16379 given type or some of its parents implement a given interface.
16380 (Collect_Abstract_Interfaces): Add support for concurrent types
16381 with interface types.
16382 (Has_Abstract_Interfaces): Add support for concurrent types with
16384 (Is_Parent): New subprogram that determines whether E1 is a parent
16385 of E2. For a concurrent type its parent is the first element of its
16386 list of interface types; for other types this function provides the
16387 same result than Is_Ancestor.
16388 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16389 (Collect_Synchronized_Interfaces): Removed because the subprogram
16390 Collect_Abstract_Interfaces provides this functionality.
16391 (Collect_Abstract_Interfaces): Minor update to give support to
16392 concurrent types and thus avoid undesired code duplication.
16393 (Get_Subprogram_Entity): Handle entry calls.
16394 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16396 (Enter_Name): Do not give -gnatwh hiding warning for record component
16397 entities, they never result in hiding.

16412 can be an E_Return_Statement.
16413 (Is_Coextension): New flag for allocators.

16422 before propagating exception.
16424 2007-04-06 Olivier Hainque <hainque@adacore.com>

16432 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16433 expression with a COMPOUND_EXPR including the call instead of emitting
16434 the call directly here.
16435 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16436 high bound is constant and the slice is empty. Tidy.
16437 (tree_transform, case N_Op_Not): Handle properly the case where the
16438 operation applies to a private type whose full view is a modular type.
16439 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16440 Address_Clause, use the associated Expression as the GNAT tree
16441 representing the choice value to ensure the corresponding GCC tree is
16442 of the proper kind.
16443 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16444 instead of just the operands, as the base GCC stabilize_reference does.
16445 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16446 requested; otherwise fail.
16447 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16452 implementation of UI_Div.
16453 (UI_Div): Reimplement as a call to UI_Div_Rem.
16454 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16455 remainder, avoiding the cost of a multiplication and a subtraction.
16456 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
16457 provides both quotient and remainder in a single computation.
16458 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
16459 functions for uint.
16460 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
16461 is undefined if the given n is not inversible.
16463 2007-04-06 Olivier Hainque <hainque@adacore.com>
16465 * utils2.c (known_alignment): Handle COMPOUND_EXPR, COND_EXPR and

16470 Olivier Hainque <hainque@adacore.com>
16472 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
16473 when updating the contents of the old pointer to an unconstrained array.

16707 (mainly static expression evaluation).
16708 Reword some continuation messages
16709 Add some \\ sequences to continuation messages
16710 (Resolve_Call): Refine infinite recursion case. The test has been

16724 during analysis, and use May_Be_Lvalue to distinguish read/write.
16725 (Valid_Array_Conversion): New procedure, abstracted from
16726 Valid_Conversion, to incorporate accessibility checks for arrays of
16727 anonymous access types.
16728 (Valid_Conversion): For a conversion to a numeric type occurring in an
16729 instance or inlined body, no need to check that the operand type is
16730 numeric, since this has been checked during analysis of the template.
16731 Remove legacy test for scope name Unchecked_Conversion.

17452 Typ'Acc, where Acc is an access attribute, the expression comes from a
17453 default initialized self-referential component.
17454 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17455 that has been derived from several abstract interfaces we must also
17456 initialize the tags of the secondary dispatch tables.

17460 Javier Miranda <miranda@adacore.com>
17461 Robert Dewar <dewar@adacore.com>
17464 (Expand_Access_To_Protected_Op): If the context indicates that an access
17465 to a local operation may be transfered outside of the object, create an
17466 access to the wrapper operation that must be used in an external call.
17467 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17468 target, pass the Valid attribute applied to a floating-point prefix on
17469 to the back end without expansion.
17470 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17471 the allocated storage when it is specified by a per-object expression.
17472 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17473 Nothing to do here, the attribute has been rewritten during semantic
17475 (Expand_Attribute_Reference): Handle expansion of the new Priority
17477 (Find_Fat_Info): Handle case of universal real
17478 (Expand_Access_To_Protected_Op): Fix use of access to protected
17479 subprogram from inside the body of a protected entry.
17480 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
17481 'Access and 'Unrestricted_Access, to transform the attribute reference
17482 into a fat pointer.
17483 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17484 subcomponent's enclosing variable is aliased with a constrained subtype.
17485 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17486 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17487 an aliased prefix must be known to be constrained in order to use True
17488 for the attribute value, and now it's possible for some aliased views
17489 to be unconstrained.
17491 2006-10-31 Robert Dewar <dewar@adacore.com>
17493 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17494 (Expand_Entity_Reference): Correct error of not handling subprogram
17495 formals in current_value processing.
17497 2006-10-31 Javier Miranda <miranda@adacore.com>
17498 Robert Dewar <dewar@adacore.com>
17499 Ed Schonberg <schonberg@adacore.com>
17500 Gary Dismukes <dismukes@adacore.com>
17502 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17503 register in the final list objects containing class-wide interfaces;
17504 otherwise we incorrectly register the tag of the interface in the final
17506 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17507 generate the wrapper if the parent primitive is abstract. This is
17508 required to report the correct error message.
17509 (Expand_N_Subtype_Indication): Do validity checks on range
17510 (Clean_Task_Names): If an initialization procedure includes a call to
17511 initialize a task (sub)component, indicate that the procedure will use
17512 the secondary stack.
17513 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17514 compatibility for interfacing with CPP by default.
17515 (Expand_N_Object_Declaration): Only build an Adjust call when the
17516 object's type is a nonlimited controlled type.
17517 * exp_ch3.adb: Add with and use of Exp_Ch6.
17518 (Expand_N_Object_Declaration): Check for object initialization that is a
17519 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17520 Object_Declaration to the call.
17521 (Freeze_Type): When the designated type of an RACW was not frozen at the
17522 point where the RACW was declared, validate the primitive operations
17523 with respect to E.2.2(14) when it finally is frozen.
17524 (Build_Initialization_Call,Expand_Record_Controller): Rename
17525 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17526 return-by-reference has no meaning in Ada 2005.
17527 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17528 to register tag of the immediate ancestor interfaces in the
17529 run-time structure.
17530 (Init_Secondary_Tags): Moved to the specification to allow the
17531 initialization of extension aggregates with abstract interfaces.
17532 (Build_Master_Renaming): Make public, for use by function declarations
17533 whose return type is an anonymous access type.
17534 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17535 Insert_List_Before_And_Analyze after the generation of the specs
17536 associated with null procedures.
17537 (Expand_Tagged_Root): Update documentation in its specification.
17538 (Init_Secondary_Tags): Update documentation.
17539 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17540 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17541 then generate code to inherit the contents of the dispatch table
17542 directly from the ancestor.
17543 (Expand_Record_Controller): Insert controller component after tags of
17544 implemented interfaces.
17545 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17546 create null procedure overridings when null procedures are inherited
17548 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17549 declarations for overriding null primitives inherited from interfaces.
17550 (Is_Null_Interface_Procedure): New function in
17551 Make_Null_Procedure_Specs.
17552 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17553 immediate ancestor of a tagged type is an abstract interface type we
17554 must generate the specification of the predefined primitives associated
17555 with controlled types (because the dispatch table of the ancestor is
17556 null and hence these entries cannot be inherited). This is required to
17557 elaborate well the dispatch table.

17565 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
17567 (Expand_N_In): Do validity checks on range
17568 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17569 (Expand_N_Allocator): For "new T", if the object is constrained by
17570 discriminant defaults, allocate the right amount of memory, rather than
17571 the maximum for type T.
17572 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17573 when the allocator is initialized by a build-in-place call, since the
17574 allocator is already rewritten as a reference to the function result,
17575 and this prevents an unwanted duplication of the function call.
17576 Add with and use of Exp_Ch6.
17577 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17578 is a call to build-in-place function and apply
17579 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17580 untagged designated types).
17581 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17582 optimization if source or target is biased.
17583 (Expand_N_Allocator): Add comments for case of an allocator within a
17584 function that returns an anonymous access type designating tasks.
17585 (Expand_N_Allocator): apply discriminant checks for access
17586 discriminants of anonymous access types (AI-402, AI-416)

17593 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17595 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17596 (Expand_N_Assignment_Statement): Call
17597 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17598 build-in-place function call. Currently, this can happen only for
17599 assignments that come from aggregates.
17600 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17601 in order to alleviate the upward compatibility introduced by AI-318.
17602 (Expand_N_Extended_Return_Statement): Add support for handling the
17603 return object as a build-in-place result.
17604 (Expand_Non_Function_Return): Implement simple return statements nested
17605 within an extended return.
17606 (Enable_New_Return_Processing): Turn on the new processing of return
17608 (Expand_Non_Function_Return): For a return within an extended return,
17609 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17610 (Expand_N_Extended_Return_Statement): Implement AI-318
17611 (Expand_Simple_Function_Return): Ditto.
17612 (Expand_N_If_Statement): Handle new -gnatwt warning
17613 (Expand_N_Case_Statement): Handle new -gnatwt warning
17614 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17615 a protected object.
17616 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17617 validity checking of assignments to elementary record components.
17618 (Expand_N_Return_Statement): return Class Wide types on the secondary
17619 stack independantly of their controlled status since with HIE runtimes,
17620 class wide types are not potentially controlled anymore.
17622 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17625 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17626 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17627 it expects a block, procedure, or task. The return statement will get
17628 turned into a block, and Expand_Cleanup_Actions will happen then.

17631 Ed Schonberg <schonberg@adacore.com>
17632 Bob Duff <duff@adacore.com>
17633 Gary Dismukes <dismukes@adacore.com>
17635 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17637 (Expand_Inlined_Call): Tagged types are by-reference types, and
17638 therefore should be replaced by a renaming declaration in the expanded
17639 body, as is done for limited types.
17640 (Expand_Call): If this is a call to a function with dispatching access
17641 result, propagate tag from context.
17642 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17644 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17645 build-in-place when the right-hand side of an assignment is a
17646 build-in-place function call.
17647 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17648 of the explicit dereference of the allocator to the result subtype of
17649 the build-in-place function. This is needed to satisfy type checking
17650 in cases where the caller's return object is created by an allocator for
17651 a class-wide access type and the type named in the allocator is a
17653 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17654 conversion of the reference to the declared object to the result subtype
17655 of the build-in-place function. This is needed to satisfy type checking
17656 in cases where the declared object has a class-wide type. Also, in the
17657 class-wide case, change the type of the object entity to the specific
17658 result subtype of the function, to avoid passing a class-wide object
17659 without explicit initialization to the back end.
17660 (Register_Interface_DT_Entry): Moved outside the body of
17661 Freeze_Subprogram because this routine is now public; it is called from
17662 Check_Dispatching_Overriding to handle late overriding of abstract
17663 interface primitives.
17664 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17665 adding an implicit access actual on a call to a build-in-place function.
17666 (Expand_Actuals): Test for an actual parameter that is a call to a
17667 build-in-place function and apply
17668 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17669 (Is_Build_In_Place_Function): New function to determine whether an
17670 entity is a function whose calls should be handled as build-in-place.
17671 (Is_Build_In_Place_Function_Call): New function to determine whether an
17672 expression is a function call that should handled as build-in-place.
17673 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17674 calls to build-in-place functions as the initialization of an allocator.
17675 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17676 handling calls to build-in-place functions in contexts that do not
17677 involve init of a separate object (for example, actuals of subprogram
17679 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17680 handling calls to build-in-place functions as the initialization of an
17681 object declaration.
17682 (Detect_Infinite_Recursion): Add explicit parameter Process to
17683 instantiation of Traverse_Body to avoid unreferenced warning.
17684 (Check_Overriding_Inherited_Interfaces): Removed.
17685 (Register_Interface_DT_Entry): Code cleanup.
17686 (Register_Predefined_DT_Entry): Code cleanup.
17687 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17688 inlined statements if within a transient scope.
17689 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17690 formal parameters with occurrences of actuals in inlined body, establish
17691 visibility on the proper view of the actual's subtype for the body's
17693 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17694 compatibility mode and we have an imported CPP subprogram because
17695 for now we assume that imported CPP primitives correspond with
17696 objects whose constructor is in the CPP side (and therefore we
17697 don't need to generate code to register them in the dispatch table).
17698 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17699 aligned selected component.
17700 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17701 the actual of an in-mode parameter is a type conversion.
17702 (Expand_Actuals): If the call does not come from source and the actual
17703 is potentially misaligned, let gigi handle it rather than rejecting the
17704 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17705 Class Wide types as returning by reference independantly of their
17706 controlled status since with HIE runtimes class wide types are not
17707 potentially controlled anymore.
17709 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17711 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17712 references that are private components of the protected object.
17713 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
17714 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17715 instantiation to deal with warnings.
17716 (Initialize_Protection): If expression for priority is non-static, use
17717 System_Priority as its expected type, in case the expression has not
17720 2006-10-31 Robert Dewar <dewar@adacore.com>
17722 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17723 initialization of Homonym_Len.
17724 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17725 names from fully qualified name. Fixes problem of duplicate
17726 external names differing only in the presence of such a block name.
17728 2006-10-31 Thomas Quinot <quinot@adacore.com>
17729 Pablo Oliveira <oliveira@adacore.com>
17731 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17732 subprogram Ids, even if they are not yet assigned.
17733 (Build_Subprogram_Id): It is now this function that will take care of
17734 calling Assign_Subprogram_Ids if necessary.
17735 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17736 should be done only once they are assigned.
17737 (Build_From_Any_Function, case of tagged types): Add missing call to
17739 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17740 type for an RACW type.
17741 (Add_RACW_Features): When processing an RACW declaration for which the
17742 designated type is already frozen, enforce E.2.2(14) rules immediately.
17743 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17744 special reordering of controlling formals.
17746 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17747 associated stub type for an RACW type.
17749 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17751 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17752 fixed-point operations in an integer context, i.e. as operands of a
17753 conversion to an integer type, indicate that result must be rounded.
17755 2006-10-31 Robert Dewar <dewar@adacore.com>
17757 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17758 cases, pass the encoding method, since it is now required by the run
17761 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17762 assumption that Str'First = 1.
17763 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17764 it on to the Value_Wide_Wide_Character call.
17765 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17766 properly handles a string of the form quote-encoded_wide_char-quote.
17768 * s-wchcnv.adb: Minor reformatting
17770 2006-10-31 Javier Miranda <miranda@adacore.com>
17772 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17773 run-time membership test to ensure that the constructed object
17774 implements the target abstract interface.
17776 2006-10-31 Robert Dewar <dewar@adacore.com>
17778 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17779 Machine_Attribute pragma internally to implement the user pragma.
17780 Add processing for pragma Interface so that it is now completely
17781 equivalent to pragma Import.
17783 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17784 so that it can be applied to all entities, including record components
17785 and enumeration literals.
17786 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17787 priority ranges are correct, verify compatibility against task
17788 dispatching and locking policies, and if everything is correct an entry
17789 is added to the table containing priority specific dispatching entries
17790 for this compilation unit.
17791 (Delay_Config_Pragma_Analyze): Delay processing
17792 Priority_Specific_Dispatching pragmas because when processing the
17793 pragma we need to access run-time data, such as the range of
17794 System.Any_Priority.
17795 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17796 Allow pragma Unreferenced as a context item
17797 Add pragma Preelaborable_Initialization

17799 now syntactically and semantically equivalent to Import.
17800 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17801 insertion characters.
17802 Add handling for Pragma_Wide_Character_Encoding
17803 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17804 never supercedes a real restriction, and that a real restriction
17805 always supercedes a warning.
17806 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17813 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17814 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17815 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17817 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17818 type of the function containing a return statement, because the
17819 Return_Type field was removed. We now use the Return_Applies_To field.
17821 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17822 (Build_Task_Image_Decl): If procedure is not called from an
17823 initialization procedure, indicate that function that builds task name
17824 uses the sec. stack. Otherwise the enclosing initialization procedure
17825 will carry the indication.
17826 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17827 N_Object_Declaration instead.
17828 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17829 conditional dead code killed, and change implementation accordingly.
17830 (Insert_Actions): Add N_Return_Object_Declaration case.
17831 Correct comment to mention N_Extension_Aggregate node.
17832 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17833 attempts to save information for global variables which cannot be
17835 (Get_Current_Value_Condition): Handle conditions the other way round
17836 (constant on left). Also handle right operand of AND and AND THEN

17839 (Get_Current_Value_Condition): Handle simple boolean operands
17840 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17841 (Get_Current_Value_Condition): If the variable reference is within an
17842 if-statement, does not appear in the list of then_statments, and does
17843 not come from source, treat it as being at unknown location.
17844 (Get_Current_Value_Condition): Enhance to allow while statements to be
17845 processed as well as if statements.
17846 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17848 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17849 of loop. This is safe now that we fixed Kill_Current_Values.
17850 (OK_To_Do_Constant_Replacement): Check whether current scope is
17851 Standard, before examining outer scopes.
17853 2006-10-31 Vincent Celier <celier@adacore.com>
17855 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17856 When True, apply VMS treatment to children of packages A, G, I and S.
17859 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17861 2006-10-31 Robert Dewar <dewar@adacore.com>

17886 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17887 use clauses, to avoid messages on packages used to qualify, and also
17888 to avoid messages from obsolescent units.
17889 (Warn_On_Useless_Assignments): Don't generate messages for imported
17890 and exported variables.
17891 (Warn_On_Useless_Assignments): New procedure
17892 (Output_Obsolescent_Entity_Warnings): New procedure
17893 (Check_Code_Statement): New procedure
17895 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
17896 Change name Is_Ada_2005 to Is_Ada_2005_Only
17897 (Last_Assignment): New field for useless assignment warning
17899 2006-10-31 Olivier Hainque <hainque@adacore.com>
17901 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17902 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17904 2006-10-31 Bob Duff <duff@adacore.com>
17905 Robert Dewar <dewar@adacore.com>
17906 Ed Schonberg <schonberg@adacore.com>
17908 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17909 Ada 95 mode, because it violates the new rules for AI-318.
17911 * g-awk.ads: Use overloaded subprograms in every case where we used to
17912 have a default of Current_Session. This makes the code closer to be
17913 correct for both Ada 95 and 2005.
17915 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17916 code, relying on the fact that the compiler generates a warning
17917 instead of an error in -gnatg mode.
17919 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17920 E_Return_Statement entity kind.
17921 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17923 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17924 report an error if the reserved word abstract has been previously found.
17925 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17927 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17928 parenthesized range attribute usage
17929 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17931 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17932 in the syntax for extended_return_statement. This is not in the latest
17933 RM, but the ARG is expected to issue an AI allowing this.
17934 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17935 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17936 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17937 P_Return_Statement): Parse the new syntax for extended_return_statement.
17939 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17940 Output_End_Missing): Add error-recovery code for the new
17941 extended_return_statement syntax; that is, the new E_Return entry on
17944 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17945 limited to nonlimited, because otherwise we violate the new Ada 2005
17946 rules about returning limited types in function Create_AST_Handler in
17949 * sem.adb (Analyze): Add cases for new node kinds
17950 N_Extended_Return_Statement and N_Return_Object_Declaration.
17952 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17953 type is in the same category as type of context before applying check,
17954 to prevent anomalies in instantiations.
17955 (Resolve_Aggregate): Remove test for limited components in aggregates.
17956 It's unnecessary in Ada 95, because if it has limited components, then
17957 it must be limited. It's wrong in Ada 2005, because limited aggregates
17959 (Resolve_Record_Aggregate): Move check for limited types later, because
17960 OK_For_Limited_Init requires its argument to have been resolved.
17961 (Get_Value): When copying the component default expression for a
17962 defaulted association in an aggregate, use the sloc of the aggregate
17963 and not that of the original expression, to prevent spurious
17964 elaboration errors, when the expression includes function calls.
17965 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17966 were missing. We also didn't handle qualified expressions. Now also
17967 allow function calls. Use new common routine OK_For_Limited_Init.
17968 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17969 with space can upper case letter).
17971 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17972 Has_Static_Discriminants flag
17973 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17974 type with discriminants.
17975 (Process_Range_Expr_In_Decl): Do validity checks on range
17976 (Build_Discriminant_Constraints): Use updated form of
17977 Denotes_Discriminant.
17978 (Process_Subtype): If the subtype is a private subtype whose full view
17979 is a concurrent subtype, introduce an itype reference to prevent scope
17981 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17982 Record_Type_Declaration): The functionality of the subprograms
17983 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17984 is now performed by a single routine.
17985 (Build_Derived_Record_Type): If the type definition includes an explicit
17986 indication of limitedness, then the type must be marked as limited here
17987 to ensure that any access discriminants will not be treated as having
17988 a local anonymous access type.
17989 (Check_Abstract_Overriding): Issue a detailed error message when an
17990 abstract subprogram was not overridden due to incorrect mode of its
17992 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17993 synchronized private extension declarations. Verify that the ancestor is
17994 a limited or synchronized interface or in the generic case, the ancestor
17995 is a tagged limited type or synchronized interface and all progenitors
17996 are either limited or synchronized interfaces.
17997 Derived_Type_Declaration): Check for presence of private extension when
17998 dealing with synchronized formal derived types.
17999 Process_Full_View): Enchance the check done on the usage of "limited" by
18000 testing whether the private view is synchronized.
18001 Verify that a synchronized private view is completed by a protected or
18003 (OK_For_Limited_Init_In_05): New function.
18004 (Analyze_Object_Declaration): Move check for limited types later,
18005 because OK_For_Limited_Init requires its argument to have been resolved.
18006 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18007 in order to alleviate the upward compatibility introduced by AI-318.
18008 (Constrain_Corresponding_Record): If the constraint is for a component
18009 subtype, mark the itype as frozen, to avoid out-of-scope references to
18010 discriminants in the back-end.
18011 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18012 this subprogram against wrong sources.
18013 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18014 discriminant of limited type completed with a protected type, when the
18015 discriminant is used to constrain a private component of the type, and
18016 expansion is disabled.
18017 (Find_Type_Of_Object): Do not treat a return subtype that is an
18018 anonymous subtype as a local_anonymous_type, because its accessibility
18019 level is the return type of the enclosing function.
18020 (Check_Initialization): In -gnatg mode, turn the error "cannot
18021 initialize entities of limited type" into a warning.
18022 (OK_For_Limited_Init): Return true for generated nodes, since it
18023 sometimes violates the legality rules.
18024 (Make_Incomplete_Declaration): If the type for which an incomplete
18025 declaration is created happens to be the currently visible entity,
18026 preserve the homonym chain when removing it from visibility.
18027 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18028 inherited subprograms.
18029 (Access_Definition): If this is an access to function that is the return
18030 type of an access_to_function definition, context is a type declaration
18031 and the scope of the anonymous type is the current one.
18032 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18033 incomplete subtype to the set of private dependents of the original
18035 (Constrain_Discriminated_Type): Emit an error message whenever an
18036 incomplete subtype is being constrained.
18037 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18038 corresponding subtype of the full view of the original incomplete type.
18039 (Check_Incomplete): Properly detect invalid usage of incomplete types
18042 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18044 * g-catiio.ads, g-catiio.adb (Value): New function.

18053 Robert Dewar <dewar@adacore.com>
18055 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18056 handling executable extension manually and duplicating code.
18058 * make.adb: Implement new -S switch
18059 (Gnatmake): Use new function Osint.Executable_Name instead
18060 of handling executable extension manually.
18062 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18063 is specified, the executable name ends with this suffix.
18064 Take advantage of Osint.Executable_Name instead of duplicating code.
18066 * switch-m.adb: Recognize new gnatmake -S switch
18068 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18070 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18073 * makeusg.adb: Add line for gnatmake -S switch
18075 2006-10-31 Vincent Celier <celier@adacore.com>
18077 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18078 call it with -static-libgcc, as there are some platforms, such as
18079 Darwin, where one of these two switches is compulsory to link.
18081 2006-10-31 Vincent Celier <celier@adacore.com>
18083 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18084 instead of ADA_PROJECT_PATH, for the project path.
18085 (Gnatls): When displaying the project path directories, use host dir
18088 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18089 names in the project path, as absolute paths may correspond to
18090 multi-valued VMS logical names.
18092 2006-10-31 Vincent Celier <celier@adacore.com>
18094 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18095 absolute path name.
18096 (Locate_Regular_File): Ditto
18097 (Change_Dir): Remove, no longer used
18098 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18099 on Windows. Get it calling Get_Current_Dir.
18100 (OpenVMS): Remove imported boolean, no longer needed.
18101 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18102 (Pid_To_Integer): New function to convert a Process_Id to Integer
18104 2006-10-31 Thomas Quinot <quinot@adacore.com>

18107 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18109 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18112 2006-10-31 Robert Dewar <dewar@adacore.com>

18119 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
18121 2006-10-31 Robert Dewar <dewar@adacore.com>
18123 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18125 (Layout_Variant_Record): Retrieve the discriminants from the entity
18126 rather than from the type definition, because in the case of a full
18127 type for a private type we need to take the discriminants from the
18129 (Layout_Component_List): When applying the Max operator to variants with
18130 a nonstatic size, check whether either operand is static and scale that
18131 operand from bits to storage units before applying Max.
18132 (Layout_Type): In VMS, if a C-convention access type has no explicit
18133 size clause (and does not inherit one in the case of a derived type),
18134 then the size is reset to 32 from 64.
18136 2006-10-31 Vincent Celier <celier@adacore.com>
18138 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18139 its file has already been loaded, according to the unit being loaded,
18140 not to the current value of Multiple_Unit_Index.
18142 2006-10-31 Thomas Quinot <quinot@adacore.com>
18143 Eric Botcazou <ebotcazou@adacore.com>

18175 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18178 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18180 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18181 Process_Body_Clauses): If the context of a body includes a use clause
18182 for P.Q then a with_clause for P in the same body is not redundant,
18183 even if the spec also has a with_clause on P.
18184 Add missing continuation mark to error msg
18185 (Build_Limited_Views): A limited view of a type is tagged if its
18186 declaration includes a record extension.
18187 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18188 node, even if the subunit has errors. This avoids malfunction by
18189 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18190 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18191 generation of obsolescent messages for with statements (cannot do
18192 this too early, or we cannot implement avoiding the messages in the
18193 case of obsolescent units withing obsolescent units).
18194 (Install_Siblings): If the with_clause is on a remote descendant of
18195 an ancestor of the current compilation unit, find whether there is
18196 a sibling child unit that is immediately visible.
18197 (Remove_Private_With_Clauses): New procedure, invoked after completing
18198 the analysis of the private part of a nested package, to remove from
18199 visibility the private with_clauses of the enclosing package
18201 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18202 now centralized in Generate_Reference.
18203 (Install_Limited_Context_Clauses): Remove superfluous error
18204 message associated with unlimited view visible through use
18205 and renamings. In addition, at the point in which the error
18206 is reported, we add the backslash to the text of the error
18207 to ensure that it is reported as a single error message.
18208 Use new // insertion for some continuation messages
18209 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18210 to create implicit with_clause for parent unit mentioned in original
18211 limited_with_clause.
18212 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18213 unit is a child unit. For ASIS queries.
18214 (Analyze_Subunit): If the subunit appears within a child unit, make all
18215 ancestor child units directly visible again.

18230 a formal object declaration with an access definition or a subtype mark
18231 with a null exclusion.
18232 (P_Generic_Association): Handle association with box, and others_choice
18233 with box, to support Ada 2005 partially parametrized formal packages.
18235 2006-10-31 Robert Dewar <dewar@adacore.com>
18236 Javier Miranda <miranda@adacore.com>

18241 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18242 private extensions.
18243 (P_Type_Declaration): Add the new actual Abstract_Present to every call

18245 (P_Interface_Type_Definition): Addition of one formal to report an error
18246 if the reserved word abstract has been previously found.
18247 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18248 object renaming declaration with an access definition or subtype mark
18249 with a possible null exclusion.

18271 2006-10-31 Vincent Celier <celier@adacore.com>
18273 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18274 on VMS, change "__" to '.' before checking the name.
18275 (Record_Ada_Source): Always add the source file name in the list of
18276 of sources, even if it is not the first time, as it is for another
18278 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18279 dot, instead of replacing only the first '_'.
18281 * prj-part.adb (Parse): Convert project file path to canonical form
18283 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18284 extended, the project id of the project extending it is recorded in its
18285 data, even when it has already been processed as an imported project.
18287 2006-10-31 Robert Dewar <dewar@adacore.com>

18293 Robert Dewar <dewar@adacore.com>
18295 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18296 only a restriction warning is active for the given restriction. This is
18297 desirable because we do not want to modify code in the case where only
18299 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18300 causes overriding of real restrictions.
18301 Take advantage of new No_Restrictions constant.
18303 * raise.h: (__gnat_set_globals): Change profile.
18305 2006-10-31 Arnaud Charlet <charlet@adacore.com>

18332 (OK_Self_Reference): New subprogram to check the legality of an access
18333 attribute whose prefix is the type of an enclosing aggregate.
18334 Generalizes previous mechanism to handle attribute references nested
18335 arbitrarily deep within the aggregate.
18336 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18337 can appear in an aggregate if this is a default-initialized aggregate
18338 for a self-referential type.
18339 (Resolve_Attribute, case Access): Ditto.
18340 Add support for new implementation defined attribute Stub_Type.
18341 (Eval_Attribute, case Attribute_Stub_Type): New case.
18342 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18343 (Stream_Attribute_Available): Implement using new subprogram from

18345 Has_Specified_Stream_Attribute flag.
18346 Disallow Storage_Size and Storage_Pool for access to subprogram
18347 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18348 access types of return subtypes in extended return statements. Remove
18349 accessibility checks on anonymous access types when Unchecked_Access is

18352 a class-wide interface to a tagged type.
18353 Add support for the attribute Priority.

18355 whether the designated type is discriminated with a constrained partial
18356 view and require static matching in that case.
18357 Add local variable Des_Btyp. The Designated_Type
18358 of an access to incomplete subtype is either its non-limited view if
18359 coming from a limited with or its etype if regular incomplete subtype.
18361 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18362 Fix predicate to identify and allow cases of (expander-generated)
18363 references to tag of designated object of a RACW.
18364 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18365 non-static, and therefore cannot appear as a primary in a preelaborable
18367 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18368 Has_Read_Write_Attributes.
18369 (Has_Read_Write_Attributes): Reimplement in termes of
18370 Has_Stream_Attribute_Definition.
18371 (Missing_Read_Write_Attributes): When checking component types in a
18372 record, unconditionally call Missing_Read_Write_Attributes recursively
18373 (remove guard checking for Is_Record_Type / Is_Access_Type).
18375 2006-10-31 Robert Dewar <dewar@adacore.com>
18377 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18378 useless assignments here and conditionalize it on absence of exception
18380 (Analyze_Exception_Handlers): Small code reorganization of error
18381 detection code, for new handling of formal packages.
18383 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18384 Hristian Kirtchev <kirtchev@adacore.com>
18386 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18387 that has been constant-folded, preserve information of original tree,
18389 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18390 generated private extension declaration if the formal derived type is
18391 synchronized. Carry synchronized present over to the generated private
18393 (Validate_Derived_Type_Instance): Ensure that the actual of a
18394 synchronized formal derived type is a synchronized tagged type.
18395 (Instantiate_Formal_Package): When creating the instantiation used to
18396 validate the actual package of a formal declared without a box, check
18397 whether the formal itself depends on a prior actual.
18398 (Instantiate_Formal_Subprogram): Create new entities for the defining
18399 identifiers of the formals in the renaming declaration, for ASIS use.
18400 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18401 a renaming declaration or a subtype declaration for an actual in an
18402 instance, capture location information of declaration in generic, for
18404 (Instantiate_Formal_Package): Add comments on needed additional tests.
18405 AI-317 (partial parametrization) is fully implemented.
18406 (Validate_Private_Type_Instance): Add check for actual which
18407 must have preelaborable initialization
18408 Use new // insertion for some continuation messages
18409 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18410 Default_Expression. Add type retrieval when the declaration has an
18411 access definition. Update premature usage of incomplete type check.
18412 (Check_Access_Definition): New subsidiary routine. Check whether the
18413 current compilation version is Ada 05 and the supplied node has an
18415 (Instantiate object): Alphabetize local variables. Handle the creation
18416 of new renaming declarations with respect to the kind of definition
18417 used - either an access definition or a subtype mark. Guard against
18418 unnecessary error message in the context of anonymous access types after
18419 they have been resolved. Add check for required null exclusion in a
18420 formal object declaration.
18421 (Switch_View): A private subtype of a non-private type needs to be
18422 switched (the base type can have been switched without its private
18423 dependents because of the last branch of Check_Private_View.
18424 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18426 (Instantiate_Type): Emit an error message whenever a class-wide type of
18427 a tagged incomplete type is used as a generic actual.
18428 (Find_Actual_Type): Extend routine to handle a component type in a child
18429 unit that is imported from a formal package in a parent.
18430 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18431 agree on constrainedness, rather than checking against ultimate ancestor
18432 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18433 generic body, for navigation purposes.
18435 2006-10-31 Robert Dewar <dewar@adacore.com>
18436 Thomas Quinot <quinot@adacore.com>
18438 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18440 (New_Stream_Subprogram): When processing an attribute definition clause
18441 for a stream-oriented subprogram, record an entity node occurring at
18442 the point of clause to use for checking the visibility of the clause,
18443 as defined by 8.3(23) as amended by AI-195.
18444 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18445 New_Stream_Function and New_Stream_Procedure.
18446 (New_Stream_Function, New_Stream_Procedure): Removed.
18447 (Analyze_Attribute_Definition_Clause, case Address): Check new
18448 Alignment_Check check

18451 Javier Miranda <miranda@adacore.com>
18452 Robert Dewar <dewar@adacore.com>
18454 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18455 generate the same errors compiling under -gnatc.
18456 (Try_Object_Operation): If no candidate interpretation succeeds, but
18457 there is at least one primitive operation with the right name, report
18458 error in call rather than on a malformed selected component.
18459 (Analyze_Selected_Component): If the prefix is an incomplete type from
18460 a limited view, and the full view is available, use the full view to
18461 determine whether this is a prefixed call to a primitive operation.
18462 (Operator_Check): Verify that a candidate interpretation is a binary
18463 operation before checking the type of its second formal.
18464 (Analyze_Call): Add additional warnings for function call contexts not
18466 (Analyze_Allocator): Move the check for "initialization not allowed for
18467 limited types" after analyzing the expression. This is necessary,
18468 because OK_For_Limited_Init looks at the structure of the expression.
18469 Before analysis, we don't necessarily know what sort of expression it
18470 is. For example, we don't know whether F(X) is a function call or an
18471 indexed component; the former is legal in Ada 2005; the latter is not.
18472 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18473 were missing. We also didn't handle qualified expressions. Now also
18474 allow function calls. Use new common routine OK_For_Limited_Init.
18475 (Analyze_Type_Conversion): Do not perform some legality checks in an
18476 instance, because the error message will be redundant or spurious.
18477 (Analyze_Overloaded_Selected_Component): Do not do style check when
18478 setting an entity, since we do not know it is the right entity yet.
18479 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18480 (Analyze_Overloaded_Selected_Component): Same change
18481 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18482 since regular incomplete subtypes are transformed into corresponding
18483 subtypes of their full views.
18484 (Complete_Object_Operation): Treat name of transformed subprogram call
18485 as coming from source, for browsing purposes.
18486 (Try_Primitive_Operation): If formal is an access parameter, compare
18487 with base type of object to determine whether it is a primitive
18489 (Operator_Check): If no interpretation of the operator matches, check
18490 whether a use clause on any candidate might make the operation legal.
18491 (Try_Class_Wide_Operation): Check whether the first parameter is an
18492 access type whose designated type is class-wide.
18494 2006-10-31 Robert Dewar <dewar@adacore.com>
18495 Ed Schonberg <schonberg@adacore.com>
18496 Gary Dismukes <dismukes@adacore.com>
18498 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
18499 warn on infinite loops.
18500 Add \\ to some continuation messages
18501 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18502 (Process_Bounds): If the bounds are integer literals that result from
18503 constant-folding, and they carry a user-defined type, preserve that type
18504 rather than treating this as an integer range.
18505 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18506 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18507 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18508 left hand side of assignment.
18509 (Analyze_Assignment): Add suport to manage assigments to the attribute
18510 priority of a protected object.
18511 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18512 not just identifiers.
18513 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18514 or AND THEN for possible tracking.
18515 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18516 case of while loops so we can track values in the loop body.
18518 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18519 Hristian Kirtchev <kirtchev@adacore.com>
18520 Bob Duff <duff@adacore.com>
18522 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18523 procedure cannot be a protected operation (it is a basic_declaration,
18524 not a subprogram_declaration).
18525 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18526 Subp. Add logic for entry processing.
18527 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18528 Determine whether an entry or subprogram of a protected or task type
18529 override an inherited primitive of an implemented interface.
18530 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18531 Update the actual used in calls to Check_Overriding_Indicator.
18532 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18533 generate the proper reference to the parent unit, for cross-reference.
18534 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18536 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18537 (Add_Extra_Formal): Revise procedure to allow passing in associated
18538 entity, scope, and name suffix, and handle setting of the new
18539 Extra_Formals field.
18540 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18541 pass new parameters. Add support for adding the new extra access formal
18542 for functions whose calls are treated as build-in-place.
18543 (Analyze_A_Return_Statement): Correct casing in error message.
18544 Move Pop_Scope to after Analyze_Function_Return, because an extended
18545 return statement really is a full-fledged scope. Otherwise, visibility
18546 doesn't work right. Correct use of "\" for continuation messages.
18547 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18548 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18549 the node doesn't get properly marked as analyzed.
18550 (Analyze_Subprogram_Body): If subprogram is a function that returns
18551 an anonymous access type that denotes a task, build a Master Entity
18553 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18554 proper usage of null exclusion in a result definition.
18555 (Process_Formals): Code cleanup and new error message.
18556 (Process_Formals): Detect incorrect application of null exclusion to
18558 (Conforming_Types): Handle conformance between [sub]types and itypes
18559 generated for entities that have null exclusions applied to them.
18560 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18561 base type is an access subtype. This case arrises with null exclusions.
18562 (New_Overloaded_Entity): Do not remove the overriden entity from the
18563 homonym chain if it corresponds with an abstract interface primitive.
18564 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18565 call to the synthesized predicate Is_Incomplete_Type.
18566 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18568 (Analyze_Subprogram_Declaration): Check that abstract interface
18569 primitives are abstract or null.
18570 (Analyze_Subprogram_Specification): Remove previous check for abstract
18571 interfaces because it was not complete.
18572 (Has_Interface_Formals): Removed.
18574 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18575 Javier Miranda <miranda@adacore.com>
18577 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18578 of Analyze_Package_Body, to create Itype references for anonymous
18579 access types created in the package declaration, whose designated types
18580 may have only a limited view.
18581 (Analyze_Package_Specification): For the private part of a nested
18582 package, install private_with_clauses of enclosing compilation unit if
18583 we are in its visible part.
18584 (Declare_Inherited_Private_Subprograms): Complete barrier
18585 to ensure that the primitive operation has an alias to some parent
18586 primitive. This is now required because, after the changes done for the
18587 implementation of abstract interfaces, the contents of the list of
18588 primitives has entities whose alias attribute references entities of
18589 such list of primitives.
18590 (Analyze_Package_Specification): Simplify code that handles parent units
18591 of instances and formal packages.
18592 (Uninstall_Declarations): Check the convention consistency among
18593 primitive overriding operations of a tagged record type.

18597 Javier Miranda <miranda@adacore.com>
18598 Ed Schonberg <schonberg@adacore.com>
18600 * sem_ch8.adb: Minor error msg rewording
18601 (Undefined): When checking for misspellings, invert arguments (to get
18602 expected and found set right)
18603 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18604 (Analyze_Generic_Renaming): Same fix
18605 (Use_One_Package): Do not take into account the internal entities of
18606 abstract interfaces during the analysis of entities that are marked
18607 as potentially use-visible.
18608 (Find_Type): Handle the case of an attribute reference for
18609 implementation defined attribute Stub_Type (simply let the analysis of
18610 the attribute reference rewrite it).
18611 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18612 type that appears in a Use_Type clause.
18613 (Analyze_Object_Renaming): Add support for renaming of the Priority
18615 (Find_Type): In Ada 2005, a task type can be used within its own body,
18616 when it appears in an access definition.
18617 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18618 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18619 in a formal object declaration or in a subtype declaration.
18620 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18621 (Check_Null_Exclusion): New local routine to
18622 Analyze_Subprogram_Renaming. Check whether the formals and return
18623 profile of a renamed subprogram have required null exclusions when
18624 their counterparts of the renaming already impose them.
18625 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18626 Determine whether an entity is inside a generic scope.
18627 (In_Open_Scope): First pass of documentation update.
18628 (Find_Expanded_Name): Add support for shadow entities associated with
18629 limited withed packages. This is required to handle nested packages.
18630 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18631 that makes a renaming of a limited withed package illegal.
18633 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18634 Ed Schonberg <schonberg@adacore.com>
18636 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18637 Check_Overriding_Indicator.
18638 (Analyze_Task_Definition): Ditto.
18639 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18640 (Check_Overriding_Indicator): To find overridden interface operation,
18641 examine only homonyms that have an explicit subprogram declaration, not
18642 inherited operations created by an unrelated type derivation.
18643 (Check_Overriding_Indicator): When checking for the presence of "null"
18644 in a procedure, ensure that the queried node is a procedure
18646 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18647 type when the formal is an access to variable.
18648 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18649 (Analyze_Task_Type): Same addition
18650 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
18651 provide navigation capabilities for entries.

18658 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18659 inherited from an interface ancestor by another interface in the
18660 context of an instance as 'late'.
18661 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18662 of a call to a function that dispatches on access result.
18663 (Check_Dispatching_Operation): In case of late overriding of a primitive
18664 that covers abstract interface subprograms we register it in all the
18665 secondary dispatch tables associated with abstract interfaces.
18666 (Check_Dispatching_Call): Add check that a dispatching call is not made
18667 to a function with a controlling result of a limited type. This is a
18668 current implementation restriction.
18669 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18670 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18671 argument is an interface type that is a generic formal.
18672 (Is_Interface_Subprogram): Removed.
18673 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18674 operation, check the formals to handle the case in which it is
18675 associated with an abstract interface type.
18677 2006-10-31 Robert Dewar <dewar@adacore.com>
18678 Ed Schonberg <schonberg@adacore.com>

18692 Hristian Kirtchev <kirtchev@adacore.com>
18693 Javier Miranda <miranda@adacore.com>
18695 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18696 subprogram type to provide better diagnostics in case of ambiguity.
18697 (Covers): Handle coverage of formal and actual anonymous access types in
18698 the context of generic instantiation.
18699 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18700 abstract interface types; this is required to handle concurrent types
18701 with discriminants and abstract interface types.
18702 (Covers): Include type coverage of both regular incomplete subtypes and
18703 incomplete subtypes of incomplete type visibles through a limited with

18715 Add missing continuation marks in error msgs
18716 (Unqualify): New function for removing zero or more levels of
18717 qualification from an expression. There are numerous places where this
18718 ought to be used, but we currently only deal properly with zero or one
18720 (In_Instance); The analysis of the actuals in the instantiation of a
18721 child unit is not within an instantiation, even though the parent
18722 instance is on the scope stack.
18723 (Safe_To_Capture_Value): Exclude the case of variables that are
18725 (Check_Obsolescent): Removed
18726 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
18727 is an aliased view, even when rewritten as a reference to the target
18728 object in an assignment.
18729 (Get_Subprogram_Entity): New function
18730 (Known_To_Be_Assigned): New function
18731 (Type_Access_Level): Compute properly the access level of a return

18738 has a null exclusion depending on its Nkind.
18739 Change Is_Lvalue to May_Be_Lvalue
18740 (May_Be_Lvalue): Extensive additional code to deal with subprogram
18741 arguments (IN parameters are not Lvalues, IN OUT parameters are).
18742 (Safe_To_Capture_Value): Extend functionality so it can be used for
18743 the current value condition case.
18744 (Has_Compatible_Alignment): New function
18745 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
18746 objects to handle the Ada 2005 case, where aliasedness no longer implies
18747 that the object is constrained. In particular, for dereferenced names,
18748 the designated object must be assumed to be unconstrained.
18749 (Kill_Current_Values): Properly deal with the case where we encounter
18750 a loop in the scope chain.
18751 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
18753 (Compile_Time_Constraint_Error): Improve error message in error case
18755 * exp_ch13.adb (Expand_N_Freeze_Entity): Remove the freezing node
18756 associated with entities of abstract interface primitives.

18759 2006-10-31 Robert Dewar <dewar@adacore.com>
18761 * s-osinte-tru64.adb:
18762 Mark Asm statements Volatile to prevent warnings (seems a
18763 reasonable change anyway)
18766 * s-mastop-irix.adb: Add Volatile to Asm statements
18767 Suppresses warning, and seems appropriate in any case
18769 * s-osinte-vms.adb: Add Volatile to Asm statement
18771 * s-vaflop-vms-alpha.adb: Add Volatile to Asm statements
18773 * exp_code.ads, exp_code.adb (Asm_Input_Value): Note that Error can be

18783 Private_Extension_Declaration to the list of assertions.
18784 (Is_Entry_Barrier_Function): New flag
18785 (Has_Self_Reference): New flag on aggregates, to indicate that they
18786 contain a reference to the enclosing type, inserted through a default
18788 (Next_Rep_Item): Move from Node4 to Node5.
18789 (Entity): Add this field for N_Attribute_Definition_Clause.
18790 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
18791 (N_Return_Object_Declaration): Remove this node kind. We now use
18792 N_Object_Declaration instead.

19412 the pointer to the allocated object to reference the corresponding
19413 secondary dispatch table.
19414 (Expand_N_Op_Divide): Allow 64 bit divisions by small power of 2,

19467 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
19468 type we cannot inherit the primitive operations; we inherit the
19469 Corresponding_Record_Type (which has the list of primitive operations).
19470 (Check_Anonymous_Access_Types): When creating anonymous access types for
19471 access components, use Rewrite in order to preserve the tree structure,
19473 (Analyze_Object_Declaration): For limited types with access
19474 discriminants with defaults initialized by an aggregate, obtain
19475 subtype from aggregate as for other mutable types.
19476 (Derived_Type_Declaration): If the derived type is a limited interface,

19488 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
19489 abstract interface type, the static analysis is not enough to know if
19490 the interface is implemented or not by the source tagged type. Hence
19491 we must pass the work to the expander to generate the required code to
19492 evaluate the conversion at run-time.
19493 (Resolve_Equality_Op): Do not apply previous
19494 transformation if expansion is disasbled, to prevent anomalies when

20249 attribute Mechanism_Code is applied to renamed subprogram, modify
20250 prefix to point to base subprogram.
20251 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20253 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20254 renamed subprograms so that the front-end must replace the prefix
20257 2006-02-13 Javier Miranda <miranda@adacore.com>
20258 Gary Dismukes <dismukes@adacore.com>
20260 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20261 availability of RE_Interface_Tag.
20262 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20263 (Freeze_Record_Type): Do not generate the tables associated with
20264 timed and conditional dispatching calls through synchronized
20265 interfaces if compiling under No_Dispatching_Calls restriction.
20266 When compiling for Ada 2005, for a nonabstract
20267 type with a null extension, call Make_Controlling_Function_Wrappers
20268 and insert the wrapper function declarations and bodies (the latter
20269 being appended as freeze actions).
20270 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20271 predefined primitives associated with timed and conditional
20272 dispatching calls through synchronized interfaces if we are
20273 compiling under No_Dispatching_Calls.
20274 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20275 service is available before generating a call.
20276 (Make_Controlling_Function_Wrappers): New procedure.
20277 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20278 access-to-limited-interfaces because they can be used to reference
20279 tasks that implement such limited interface.
20280 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20281 procedure spec and body of the Offset_To_Top function that is generated
20282 when the parent of a type with discriminants has secondary dispatch
20284 (Init_Secondary_Tags): Handle the case in which the parent of the type
20285 containing secondary dispatch tables has discriminants to generate the
20286 correct arguments to call Set_Offset_To_Top.
20287 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20289 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20290 Add Wide_[Wide_]Expanded_Name.
20291 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20292 the same functionality of Get_Prim_Op_Address but applied to predefined
20293 primitive operations because the pointers to the predefined primitives
20294 are now saved in a separate table.
20295 (Parent_Size): Modified to get access to the separate table of primitive
20296 operations or the parent type.
20297 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20298 functionality of Set_Prim_Op_Address but applied to predefined primitive
20300 (Set_Signature): New subprogram used to store the signature of a DT.
20301 (Displace): If the Offset_To_Top value is not static then call the
20302 function generated by the expander to get such value; otherwise use
20303 the value stored in the table of interfaces.
20304 (Offset_To_Top): The type of the actual has been changed to Address to
20305 give the correct support to tagged types with discriminants. In this
20306 case this value is stored just immediately after the tag field.
20307 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20308 offset_to_top value is static and hence pass this value to the run-time
20309 to store it in the table of interfaces, or else if this value is dynamic
20310 and then pass to the run-time the address of a function that is
20311 generated by the expander to provide this value for each object of the
20314 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20315 (Default_Prim_Op_Count): New entity
20316 (Get_Predefined_Prim_Op_Address): New entity
20317 (Set_Predefined_Prim_Op_Address): New entity
20318 (RE_Set_Signature): New entity
20320 2006-02-13 Thomas Quinot <quinot@adacore.com>
20321 Ed Schonberg <schonberg@adacore.com>
20323 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20324 Make_Adjust_Call done for a newly-allocated object.
20326 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20327 in a subprogram are wrapped in a cleanup block, indicate that the
20328 subprogram contains an inner block with an exception handler.
20329 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20330 Adjust call is for a newly-allocated object. In that case we must not
20331 assume that the finalization list chain pointers are correct (since they
20332 come from a bit-for-bit copy of the original object's pointers) so if
20333 the attach level would otherwise be zero (no change), we set it to 4
20334 instead to cause the pointers to be reset to null.
20336 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20337 reset chain pointers to null.
20339 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20341 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20342 string, and the context requires a loop for the assignment (e.g.
20343 because the left-hand side is packed), generate a unique name for the
20344 temporary that holds the string, to prevent spurious name clashes.
20346 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20347 Javier Miranda <miranda@adacore.com>
20348 Robert Dewar <dewar@adacore.com>
20349 Gary Dismukes <dismukes@adacore.com>
20351 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20352 return unconstrained arrays.
20354 (Expand_Call): An indirect call through an access parameter of a
20355 protected operation is not a protected call.
20356 Add circuit to raise CE in Ada 2005 mode following call
20357 to Raise_Exception.
20358 (Register_DT_Entry): Do nothing if
20359 the run-time does not give support to abstract interfaces.
20360 (Freeze_Subprogram): In case of dispatching operations, do not generate
20361 code to register the operation in the dispatch table if the source
20362 is compiled with No_Dispatching_Calls.
20363 (Register_Predefined_DT_Entry): Generate code that calls the new
20364 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20365 Set_Prim_Op_Address.
20367 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20368 on array assignments if the right-hand side is a function call that has
20369 been inlined. Check is performed on the assignment in the block.
20370 (Process_Bounds): If bounds and range are overloaded, apply preference
20371 rule for root operations to disambiguate, and diagnose true ambiguity.
20372 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20373 a tag-indeterminate right-hand side even when Expander_Active is True.
20374 Needed to ensure that dispatching calls to T'Input are allowed and
20375 get the tag of the target class-wide object.
20377 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20378 an inherited primitive operation that already overrides several
20379 abstract interface primitives. For transitivity, the new entity must
20380 also override all the abstract interface primitives covered by the
20381 inherited overriden primitive.
20382 Emit warning if new entity differs from homograph in same scope only in
20383 that one has an access parameter and the other one has a parameter of
20384 a general access type with the same designated type, at the same
20385 position in the signature.
20386 (Make_Inequality_Operator): Use source locations of parameters and
20387 subtype marks from corresponding equality operator when creating the
20388 tree structure for the implicit declaration of "/=". This does not
20389 change anything in behaviour except that the decoration of the
20390 components of the subtree created for "/=" allows ASIS to get the
20391 string images of the corresponding identifiers.
20392 (Analyze_Return_Statement): Remove '!' in warning message.
20393 (Check_Statement_Sequence): Likewise.
20394 (Analyze_Subprogram_Body): For an access parameter whose designated type
20395 is an incomplete type imported through a limited_with clause, use the
20396 type of the corresponding formal in the body.
20397 (Check_Returns): Implicit return in No_Return procedure now raises
20398 Program_Error with a compile time warning, instead of beging illegal.
20399 (Has_Single_Return): Function returning unconstrained type cannot be
20400 inlined if expression in unique return statement is not an identifier.
20401 (Build_Body_To_Inline): It is possible to inline a function call that
20402 returns an unconstrained type if all return statements in the function
20403 return the same local variable. Subsidiary procedure Has_Single_Return
20404 verifies that the body conforms to this restriction.
20406 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20407 same type, and one of them is of an anonymous access type, convert
20408 the other operand to it, so that this is a valid binary operation for
20410 (Resolve_Type_Conversion): Handle subtypes of protected types and
20411 task types when accessing to the corresponding record type.
20412 (Resolve_Allocator): Add '\' in 2-line warning message.
20413 Remove '!' in warning message.
20414 (Resolve_Call): Add '\' in 2-line warning message.
20415 (Valid_Conversion): Likewise.
20416 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20417 resulting type may be an access type with an implicit dereference.
20418 Obtain the proper component from the designated type.
20419 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20420 given by an expanded name with prefix Standard, when the operands are
20421 of an anonymous access type.
20422 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20423 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20424 prefix of the expression is not of an incomplete type. Allows full
20425 diagnoses of all semantic errors.
20426 (Resolve_Actuals): If the actual is an allocator whose directly
20427 designated type is a class-wide interface we build an anonymous
20428 access type to use it as the type of the allocator. Later, when
20429 the subprogram call is expanded, if the interface has a secondary
20430 dispatch table the expander will add a type conversion to force
20431 the displacement of the pointer.
20432 (Resolve_Call): If a function that returns an unconstrained type is
20433 marked Inlined_Always and inlined, the call will be inlined and does
20434 not require the creation of a transient scope.
20435 (Check_Direct_Boolean_Op): Removed
20436 (Resolve_Comparison_Op): Remove call to above
20437 (Resolve_Equality_Op): Remove call to above
20438 (Resolve_Logical_Op): Inline above, since this is only call.
20439 (Valid_Conversion): Handle properly conversions between arrays of
20440 convertible anonymous access types.
20443 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20444 the literal in an unchecked conversion, because GCC 4.x needs a static
20445 value for a string bound.
20447 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20448 Hristian Kirtchev <kirtchev@adacore.com>
20450 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20451 components of the corresponding record, take into account component
20452 definitions that are access definitions.
20453 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20454 procedure is not considered a dispatching call and will be expanded
20457 2006-02-13 Javier Miranda <miranda@adacore.com>
20459 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20460 controlling argument of the dispatching call is an abstract interface
20461 class-wide type then we use it directly.
20462 Check No_Dispatching_Calls restriction.
20463 (Default_Prim_Op_Position): Remove the code that looks for the last
20464 entity in the list of aliased subprograms. This code was wrong in
20466 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20467 when the source is compiled with the No_Dispatching_Calls restriction.
20468 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20469 if we are compiling with restriction No_Dispatching_Calls.
20470 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20471 subprograms if we are compiling under No_Dispatching_Calls restriction.
20472 (Make_DT): Generate a dispatch table with a single dummy entry if
20473 we are compiling with the No_Dispatching_Calls restriction. In
20474 addition, in this case we don't generate code that calls to the
20475 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20476 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20477 of this subprogram if compiling with the No_Dispatching_Calls
20479 (Expand_Type_Conversion): Instead of using the actual parameter,
20480 the argument passed as parameter to the conversion function was
20481 erroneously referenced by the expander.
20482 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20483 Set_Predefined_Primitive_Op_Address and Set_Signature.
20484 (Expand_Dispatching_Call): Generate call to
20485 Get_Predefined_Prim_Op_Address for predefined primitives.
20486 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20487 predefined primitives.
20488 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20489 primitives we reserve one dummy entry to ensure that the tag does not
20490 point to some memory that is associated with some other object. In
20491 addition, remove all the old code that generated the assignments
20492 associated with the signature of the dispatch table and replace them
20493 by a call to the new subprogram Set_Signature.
20494 (Set_All_DT_Position): Change the algorithm because now we have a
20495 separate dispatch table associated with predefined primitive operations.
20496 (Expand_Interface_Conversion): In case of non-static offset_to_top
20497 add explicit dereference to get access to the object after the call
20498 to displace the pointer to the object.
20499 (Expand_Interface_Thunk): Modify the generation of the actual used
20500 in the calls to the run-time function Offset_To_Top to fulfil its
20502 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20504 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20506 * exp_dist.adb (Copy_Specification): For access parameters, copy
20507 Null_Exclusion flag, which will have been set for stream subprograms
20510 2006-02-13 Pascal Obry <obry@adacore.com>
20512 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20513 previous implementation was using the C runtime spawnve routine but
20514 the corresponding wait was using directly the Win32 API. This was
20515 causing some times a lock when waiting for an event using
20516 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20517 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20518 API fixes this problem.
20520 2006-02-13 Robert Dewar <dewar@adacore.com>
20522 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
20525 2006-02-13 Thomas Quinot <quinot@adacore.com>

20529 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
20530 array reference that is an explicit dereference, mark the converted
20531 (packed) array reference as analyzed to prevent a forthcoming
20532 reanalysis from resetting its type to the original (non-packed) array
20535 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20536 Javier Miranda <miranda@adacore.com>
20537 Eric Botcazou <ebotcazou@adacore.com>
20539 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20540 Is_Predefined_Primitive_Operation): When
20541 searching for the predefined equality operator, verify that operands
20542 have the same type.
20543 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20544 for the last entity in the list of aliased subprograms. This code
20545 was wrong in case of renamings.
20546 (Set_Renamed_Subprogram): New procedure
20547 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20548 Exp_Type constant computed when entering this subprogram.

20550 (OK_To_Do_Constant_Replacement): New function
20551 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20552 (Side_Effect_Free): An attribute reference 'Input is not free of
20553 side effect, unlike other attributes that are functions. (from code
20555 (Remove_Side_Effects): Expressions that involve packed arrays or records
20556 are copied at the point of reference, and therefore must be marked as
20557 renamings of objects.
20558 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20559 not a dispatching operation.
20562 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20563 elementary types in all cases.
20565 2006-02-13 Javier Miranda <miranda@adacore.com>
20567 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20568 task types when accessing to the corresponding record type.
20569 Remove '!' in warning message.
20571 2006-02-13 Olivier Hainque <hainque@adacore.com>
20573 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20574 to avoid useless and space inefficient overalignments on targets where
20575 Max_Alignment is larger than 16.
20577 2006-02-13 Pascal Obry <obry@adacore.com>
20579 * g-catiio.adb (Sec_Number): New type used to compute the number of
20580 seconds since 1-1-1970.
20581 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20582 negative numbers (years, months...) it is better to have a Natural here.
20584 (Image) [Number]: Change parameter from Long_Integer to Number.
20585 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20586 overflow for dates past year 2038.
20588 2006-02-13 Matthew Heaney <heaney@adacore.com>
20590 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20593 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20595 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20597 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20598 finalization can occur normally.
20600 2006-02-13 Vincent Celier <celier@adacore.com>
20602 * gnatcmd.adb (Rules_Switches): New table
20603 (Add_To_Rules_Switches): New procedure
20604 (GNATCmd): For command CHECK, put all options following "-rules" in the
20605 Rules_Switches table. Append these -rules switches after the -cargs
20608 2006-02-13 Robert Dewar <dewar@adacore.com>
20610 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20611 These two cases were generating incorrect output, and if this unit
20612 was built with checks on, generated a discriminant mismatch constraint
20615 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20616 Robert Dewar <dewar@adacore.com>
20618 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20619 view is an array type, indicate the component type as well, for
20620 navigation purposes.
20621 (Generate_Reference): Don't consider array ref on LHS to be a case
20622 of violating pragma Unreferenced.
20623 Do not give Ada 2005 warning except on real reference.
20625 2006-02-13 Vincent Celier <celier@adacore.com>
20627 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20628 main source, add switch -mdebug-main=_ada_ so that the executable can
20629 be debugged by the standard VMS debugger.
20630 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20631 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20632 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20633 of the last source, as the binding and linking phases are never
20635 Set all executable obsolete when rebuilding a library.
20637 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20640 2006-02-13 Javier Miranda <miranda@adacore.com>
20643 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20644 code to improve the error message reported when the program has
20645 declarations of abstract interface types and it is not compiled with
20646 the -gnat05 switch.
20647 (P_Access_Definition): Reorganize the code to improve the error
20648 message reported when the new Ada 2005 syntax for anonymous
20649 access types is used and the program is not compiled with the

20654 * par-ch6.adb, style.ads, styleg.adb, styleg.ads, stylesw.adb,
20655 stylesw.ads, usage.adb, vms_data.ads: Implement -gnatyI switch
20658 2006-02-13 Javier Miranda <miranda@adacore.com>
20660 * par-endh.adb (Explicit_Start_Label): Add code to protect the parser
20661 against source containing syntax errors.

20665 * prj.adb (Reset): Initialize the first element of table Namings with
20666 the standard naming data.
20668 2006-02-13 Vincent Celier <celier@adacore.com>
20670 * prj.ads (Error_Warning): New enumeration type
20672 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20673 unknown, use the location of the project to report the error.
20674 (When_No_Sources): New global variable
20675 (Report_No_Ada_Sources): New procedure
20676 (Check): New parameter When_No_Sources. Set value of global variable
20678 (Find_Sources): Call Report_No_Ada_Sources when appropriate

20680 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20683 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20684 Call Prj.Proc.Process with parameter When_No_Sources.
20686 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20687 Call Recursive_Check with parameter When_No_Sources.
20688 (Recursive_Check): New parameter When_No_Sources. Call itself and
20689 Prj.Nmsc.Check with parameter When_No_Sources.
20690 (Process): New parameter When_No_Sources. Call Check with parameter
20692 (Copy_Package_Declarations): New procedure to copy renamed parameters
20693 and setting the location of the declared attributes to the location
20694 of the renamed package.
20695 (Process_Declarative_Items): Call Copy_Package_Declarations for renamed

20700 * prj-makr.adb (Make): Preserve the comments from the original project
20702 When removing nodes (attributes Source_Dirs, Source_Files,
20703 Source_List_File and package Naming), save the comments and attach the
20704 saved comments to the newly created nodes.
20705 Do not add a with clause for the naming package if one already exists.

20714 aliased entities to look for the overriden abstract interface
20716 (Is_Interface_Subprogram): Complete documentation.
20717 (Check_Dispatching_Operation): Do not generate code to register the
20718 operation in the dispatch table if the source is compiled with
20719 restriction No_Dispatching_Calls.
20720 (Override_Dispatching_Operation): Check for illegal attempt to override
20721 No_Return procedure with procedure that is not No_Return
20722 (Check_Dispatching_Call): Suppress the check for an abstract operation
20723 when the original node of an actual is a tag-indeterminate attribute
20724 call, since the attribute, which must be 'Input, can never be abstract.
20725 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20726 call to the Input attribute (even when rewritten).
20727 (Propagate_Tag): Augment comment to indicate the possibility of a call
20728 to an Input attribute.
20730 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20731 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
20733 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
20734 No_Wide_Characters is no longer partition-wide
20735 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
20738 2006-02-13 Douglas Rupp <rupp@adacore.com>
20740 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20742 2006-02-13 Javier Miranda <miranda@adacore.com>
20744 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20745 handles default-initialized components to keep separate the management
20746 of this feature but also avoid the unrequired resolution and
20747 expansion of components that do not have partially initialized
20749 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20750 (Check_Bounds): Likewise.
20751 (Check_Length): Likewise.
20753 2006-02-13 Javier Miranda <miranda@adacore.com>
20754 Ed Schonberg <schonberg@adacore.com>
20756 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20757 abstract interface type call analyze_and_resolve to expand the type
20758 conversion into the corresponding displacement of the
20759 reference to the base of the object.
20760 (Eval_Attribute, case Width): For systems where IEEE extended precision
20761 is supported, the maximum exponent occupies 4 decimal digits.
20762 (Accessibility_Message): Add '\' in 2-line warning message.
20763 (Resolve_Attribute): Likewise.
20764 (case Attribute_Access): Significantly revise checks
20765 for illegal access-to-subprogram Access attributes to properly enforce
20766 the rules of 3.10.2(32/2).
20767 Diagnose use of current instance with an illegal attribute.
20769 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20771 (Enclosing_Generic_Unit): New function to return a node's innermost
20772 enclosing generic declaration node.
20773 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20774 (Type_Access_Level): The accessibility level of anonymous acccess types
20775 associated with discriminants is that of the current instance of the
20776 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20777 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20778 (Kill_Current_Values_For_Entity): New function
20779 (Enter_Name): Change formal type to Entity_Id
20781 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20782 Ed Schonberg <schonberg@adacore.com>
20783 Gary Dismukes <dismukes@adacore.com>
20785 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20786 Analyze_Compilation_Unit.
20787 Detect and warn on redundant with clauses detected in a package spec
20788 and/or body when -gnatwr is used.
20789 (Analyze_Context): Analyze config pragmas before other items
20790 (Install_Context_Items): Don't analyze config pragmas here
20791 (Install_Limited_Withed_Unit): Set limited entity of package in
20792 with_clause so that cross-reference information or warning messages on
20793 unused packages can be properly generated
20794 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20795 has Error_Posted set. Prevent infinite loops in illegal programs.
20796 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20797 to the point of the error test requiring the current unit to be private.
20798 This ensures that private with clauses are not exempted from the basic
20799 checking for being a descendant of the same library unit parent as a
20800 withed private descendant unit.
20801 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20802 handle private with clauses properly, as well as to account for cases
20803 where the withed unit is a public descendant of a private ancestor
20804 (in which case the current unit must be a descendant of the private
20805 ancestor's parent). The spec comments were updated accordingly. Also,
20806 the old error message in this subprogram was replaced with error
20807 messages that mirror the errors tested and reported by
20808 Check_Private_Child_Unit.
20809 Parameter and variable names improved for readability.
20810 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20811 private as the precondition for calling
20812 Check_Private_Limited_Withed_Unit since that subprogram has been
20813 revised to test public units as well as private units.

20816 Robert Dewar <dewar@adacore.com>
20817 Ed Schonberg <schonberg@adacore.com>
20818 Javier Miranda <miranda@adacore.com>
20820 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20821 that Scope_Stack.First = 1.
20822 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20823 were not always properly handled previously.
20824 (Formal_Entity): Complete rewrite, to handle properly some complex case
20825 with multiple levels of parametrization by formal packages.
20826 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20827 to the corresponding derived type declaration for proper semantics.
20829 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20830 (Check_Component): Enforce restriction on components of
20831 unchecked_unions: a component in a variant cannot contain tasks or
20833 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20835 Add pragma Ada_2005 (synonym for Ada_05)
20836 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20837 were not always properly handled previously.
20838 Document that pragma Propagate_Exceptions has no effect
20839 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20840 (Set_Convention_From_Pragma): Check that if a convention is
20841 specified for a dispatching operation, then it must be
20842 consistent with the existing convention for the operation.
20843 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20844 longer required to specify an vtable-ptr component in the record. For
20845 compatibility reasons we leave the support for the previous definition.
20846 (Analyze_Pragma, case No_Return): Allow multiple arguments
20848 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20849 non-overrideen inherited operation with a controlling result as
20850 illegal only its implicit declaration comes from the derived type
20851 declaration of its result's type.
20852 (Check_Possible_Deferred_Completion): Relocate the object definition
20853 node of the subtype indication of a deferred constant completion rather
20854 than directly analyzing it. The analysis of the generated subtype will
20855 correctly decorate the GNAT tree.
20856 (Record_Type_Declaration): Check whether this is a declaration for a
20857 limited derived record before analyzing components.
20858 (Analyze_Component_Declaration): Diagnose record types not explicitly
20859 declared limited when a component has a limited type.
20860 (Build_Derived_Record_Type): Code reorganization to check if some of
20861 the inherited subprograms of a tagged type cover interface primitives.
20862 This check was missing in case of a full-type associated with a private
20864 (Constant_Redeclaration): Check that the subtypes of the partial and the
20865 full view of a constrained deferred constant statically match.
20866 (Mentions_T): A reference to the current type in an anonymous access
20867 component declaration must be an entity name.
20868 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20869 class_wide type to refer to full type, not to the incomplete one.
20870 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20871 available. Required to give support to the certified run-time.
20872 (Analyze_Component_Declaration): In case of anonymous access components
20873 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20874 (Process_Discriminants): For an access discriminant, use the
20875 discriminant specification as the associated_node_for_itype, to
20876 simplify accessibility checks.
20878 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20879 Javier Miranda <miranda@adacore.com>
20881 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20882 abstract interpretations on an operator, remove interpretations that
20883 yield Address or a type derived from it, if one of the operands is an
20885 (Try_Object_Operation.Try_Primitive_Operation,
20886 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20887 location when creating the new reference to a primitive or class-wide
20888 operation as a part of rewriting a subprogram call.
20889 (Try_Primitive_Operations): If context requires a function, collect all
20890 interpretations after the first match, because there may be primitive
20891 operations of the same type with the same profile and different return
20892 types. From code reading.
20893 (Try_Primitive_Operation): Use the node kind to choose the proper
20894 operation when a function and a procedure have the same parameter
20896 (Complete_Object_Operation): If formal is an access parameter and prefix
20897 is an object, rewrite as an Access reference, to match signature of
20898 primitive operation.
20899 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20900 by an expanded name with prefix Standard, when the operands are of an
20901 anonymous access type.
20902 (Remove_Abstract_Operations): If the operation is abstract because it is
20903 inherited by a user-defined type derived from Address, remove it as
20904 well from the set of candidate interpretations of an overloaded node.
20905 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20908 2006-02-13 Bob Duff <duff@adacore.com>
20910 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20911 redundant use clauses.
20912 In particular, if the scope of two use clauses overlaps, but one is not
20913 entirely included in the other, we should not warn. This can happen
20914 with nested packages.
20915 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20916 reported errors. The bug was reported when the compiler was built
20917 with assertions enabled.
20918 (Find_Type): If the node is a 'Class reference and the prefix is a
20919 synchronized type without a corresponding record, return the type
20922 2006-02-13 Javier Miranda <miranda@adacore.com>
20924 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20925 if this is the full-declaration associated with a private declaration
20926 that implement interfaces, then the private type declaration must be
20928 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20929 as aliased. The use of the 'access attribute is not available for such
20930 object (for this purpose the object should be explicitly marked as
20931 aliased, but being an anonymous type this is not possible).
20933 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20934 Robert Dewar <dewar@adacore.com>
20936 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20937 compilation unit is an elaboration scope.
20938 (Add_Task_Proc): Add '\' in 2-line warning message.
20939 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20941 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20942 Javier Miranda <miranda@adacore.com>
20944 * sem_type.adb (Write_Overloads): Improve display of candidate
20946 (Add_One_Interp): Do not add to the list of interpretations aliased
20947 entities corresponding with an abstract interface type that is an
20948 immediate ancestor of a tagged type; otherwise we have a dummy
20949 conflict between this entity and the aliased entity.
20950 (Disambiguate): The predefined equality on universal_access is not
20951 usable if there is a user-defined equality with the proper signature,
20952 declared in the same declarative part as the designated type.
20953 (Find_Unique_Type): The universal_access equality operator defined under
20954 AI-230 does not cover pool specific access types.
20955 (Covers): If one of the types is a generic actual subtype, check whether
20956 it matches the partial view of the other type.
20958 2006-02-13 Thomas Quinot <quinot@adacore.com>
20960 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20961 line. This is necessary to allow In_Extended_Main_Unit to provide
20962 correct results for itypes while writing out expanded source.
20963 (Close_File): No need to update the source_index_table here since it's
20964 now done for each line.
20966 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20967 Robert Dewar <dewar@adacore.com>
20969 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20970 preserve the source unit where the itype is declared, and prevent a
20972 (Note_Implicit_Run_Time_Call): New procedure
20973 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
20976 * sprint.ads: Document use of $ for implicit run time routine call

20980 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
20983 2006-02-13 Bob Duff <duff@adacore.com>
20985 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20986 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20987 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20988 raise Constraint_Error.
20990 * s-vallli.adb (Scan_Long_Long_Integer): Call
20991 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20992 do not scan leading blanks and sign twice.
20993 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20994 raise Constraint_Error.
20996 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20997 Scan_Long_Long_Unsigned): Split out most of the processing from
20998 Scan_Long_Long_Unsigned out into
20999 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21000 This prevents scanning leading blanks and sign twice.
21001 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21004 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21005 out most of the processing from Scan_Unsigned out into
21006 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21007 This prevents scanning leading blanks and sign twice.
21009 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21010 use with Modular'Value attribute.
21011 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

21209 * a-taster.ads, a-taster.adb: New files.
21211 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21212 link to the version that does nothing. This way the task termination
21213 routine is not executed twice for the environment task when finishing
21214 because of an unhandled exception.
21216 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21217 handler because of an unhandled exception.
21219 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
21220 System.Tasking.Utilities instead of that in System.Tasking.Stages.

21225 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21226 non-tasking version of the soft link for task termination. We do
21227 nothing since if we are using the non-tasking version it
21228 means that the task termination functionality is not used.
21229 (Null_Finalize_Global_List): Add this null version for the procedure
21230 in charge of finalizing the global list for controlled objects.
21231 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21232 instead for handling run-time termination in a more flexible way.
21233 (Adafinal_NT): This new procedure will take care of finalizing the
21234 global list for controlled objects if needed, but no tasking
21237 * s-tarest.adb (Task_Lock): Do not try to lock again the
21238 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21239 some run-time operations.
21240 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21241 until all nested locks have been released.
21242 (Task_Wrapper): Call the fall-back task termination handler. It
21243 applies to all tasks but the environment task.
21244 (Finalize_Global_Tasks): Add the call for the task termination
21245 procedure for the environment task.
21246 (Task_Wrapper): suppress warnings around declaration of
21247 Secondary_Stack_Address.
21249 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21250 moved to the Common_ATCB record.
21251 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21252 Common_ATCB record.
21253 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21254 Common_ATCB record.
21256 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21257 Fall_Back_Handler, and Specific_Handler.
21259 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21260 defined in Ada.Task_Termination, to avoid circular dependencies.
21261 (Termination_Handler): Redefine this type here, alredy defined in
21262 Ada.Task_Termination, for avoiding circular dependencies.
21263 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21264 for storing task termination handlers. In addition,
21265 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21266 Common_ATCB because it is used by both the regular and the restricted
21268 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21269 Common_ATCB because it is used by both the regular and the restricted
21271 (Common_ATCB): Added a dynamic task analyzer field.
21273 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21274 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.

21276 tasks but the environment task.
21277 (Finalize_Global_Tasks): Call the task termination procedure for the
21278 environment task. The call to Finalize_Global_List is now performed
21279 using the soft links mechanism.
21280 (Task_Wrapper): added dynamic stack analysis.
21282 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21283 potentially blocking operations has been moved from
21284 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21285 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21286 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21287 this run-time check.
21289 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21290 of task termination procedure.
21291 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21292 link for the task termination procedure.

21333 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21334 to the specification because the frontend generates code that uses this
21336 (Set_Interface_Table): Add missing assertion.
21337 Update documentation describing the run-time structure.
21338 (Displace): New subprogram that displaces the pointer to the object
21339 to reference one of its secondary dispatch tables.
21340 (IW_Membership): Modified to use the new table of interfaces.
21341 (Inherit_TSD): Modified to use the new table of interfaces.
21342 (Register_Interface_Tag): Use the additional formal to fill the
21343 contents of the new table of interfaces.
21344 (Set_Interface_Table): New subprogram that stores in the TSD the

21359 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21360 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21361 record component containing the tag of the secondary dispatch table we
21362 have to use the Offset_To_Top run-time function to get this information;
21363 otherwise if the pointer to the base of the object has been displace
21364 we get a wrong value if we use the 'position attribute.
21366 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21367 all the calls to Expand_Interface_Thunk.
21368 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
21369 interfaces; hence the call to Set_Interface_Table was clearly wrong.

21371 ensure that the interfaces implemented by the ancestors are placed
21372 at the header of the generated list.
21373 (Expand_Interface_Conversion): Handle the case in which the displacement
21374 associated with the interface conversion is not statically known. In
21375 this case we generate a call to the new run-time subprogram Displace.

21377 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21378 Get_Tagged_Kind and Set_Tagged_Kind.

21402 RE_TK_Tagged, RE_TK_Task.
21404 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21405 Init_Secondary_Tags_Internal to allow its use with interface types and
21406 also to generate the code for the new additional actual required
21407 by Set_Offset_To_Top.
21408 (Build_Init_Statements): In case of components associated with abstract
21409 interface types there is no need to generate a call to its IP.
21410 (Freeze_Record_Type): Generate Select Specific Data tables only for

21419 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21420 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21421 properly protected objects and attach handler in the case of the
21422 restricted profile.
21423 Move embeded package Select_Expansion_Utilities into a separate external
21425 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,

21435 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21436 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21437 about the use and expansion of SAVE_EXPRs in the various possible
21438 renaming handling cases.
21439 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21440 abusing DECL_FCONTEXT.

21610 are implemented by the ancestors.
21611 (Derived_Type_Declaration): If the parent of the full-view is an
21612 interface perform a transformation of the tree to ensure that it has
21613 the same parent than the partial-view. This simplifies the job of the
21614 expander in order to generate the correct object layout, and it is
21615 needed because the list of interfaces of the full-view can be given in
21617 (Process_Full_View): The parent of the full-view does not need to be
21618 a descendant of the parent of the partial view if both parents are
21620 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21621 "limited" the parent must be a limited type.
21622 (Build_Derived_Record_Type): A derived type that is explicitly limited
21623 must have limited ancestor and progenitors.
21624 (Build_Derived_Type): Ditto.

21695 available user-specified stream attributes on limited parameters to
21696 also test the type directly rather than only its underlying type (for
21697 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21698 attributes are visible at the point of the subprogram declaration.
21699 For Ada 2005, the error message is modified to indicate that the
21700 type's stream attributes must be visible (again, only for -gnat05).

21732 types use the corresponding record type. This was not needed before
21733 the implementation of Ada 2005 synchronized types because
21734 concurrent types were never tagged types in Ada 95.

21862 * socket.c: Add extern int h_errno for rtems since networking header
21863 files are not available at this point in a tool bootstrap. Newlib

21980 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
21981 elementary types using the operator in standard. It is cleaner not to
21982 modify the programmers intent, especially in the case of floating-point.
21983 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
21984 it did not matter because we always rewrote a/=b to not(a=b).
21985 (Expand_Allocator_Expression): For an allocator expression whose nominal
21986 subtype is an unconstrained packed type, convert the expression to its
21987 actual constrained subtype.
21988 Implement warning for <= or >= where < or > not possible
21989 Fix to Vax_Float tests (too early in many routines, causing premature
21990 Vax_Float expansions.

22008 Allow optional = after -gnatm
22009 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22010 longer sets Elaboration_Checks.
22011 Code to set warning mode moved to Sem_Warn
22012 so that it can be shared by pragma processing.
22014 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if

22026 * exp_vfpt.adb: Handle /= case
22027 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22172 * trans.c (tree_transform, case N_Attribute_Reference, case Attr_Size &
22173 related): For a prefix that is a dereference of a fat or thin pointer,
22174 if there is an actual subtype provided by the front-end, use that
22175 subtype to build an actual type with bounds template.
22176 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22177 is provided by the front-end, use that subtype to compute the size of
22178 the deallocated object.
22179 (gnat_to_gnu): When adding a statement into an elaboration procedure,
22180 check for a potential violation of a No_Elaboration_Code restriction.
22181 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22182 with extra arguments to control whether to recurse through non-values
22183 and to let the caller know if the stabilization has succeeded.
22184 (gnat_stabilize_reference): Now a simple wrapper around
22185 maybe_stabilize, for common uses without restriction on lvalues and
22186 without need to check for the success indication.
22187 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22188 pass false instead of 0 as the FORCE argument which is a bool.
22189 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22190 attached to a renaming pointer has been properly stabilized, as no such
22191 object is attached otherwise.
22192 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22193 function uses the "target pointer" return mechanism.
22194 Reinstate conversion of the actual to the type of the formal
22195 parameter before any other specific treatment based on the passing
22196 mechanism. This turns out to be necessary in order for PLACEHOLDER
22197 substitution to work properly when the latter type is unconstrained.

22203 and to let the caller know if the stabilization has succeeded.
22205 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22206 static output of record constructor if all the components are constant.
22207 (gnat_build_constructor): For a record type, sort the list of field
22208 initializers in increasing bit position order.
22209 Factor common code to build a storage type for an unconstrained object
22210 from a fat or thin pointer type and a constrained object type.
22211 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22212 types variants, and process special cases of VIEW_CONVERT expressions
22213 as their NOP_EXPR counterpart to ensure we get to the
22214 CORRESPONDING_VARs associated with CONST_DECls.
22215 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22216 on the right-hand side.
22218 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
22220 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
22221 are converting back to its original type.
22222 (convert) <JM input>: Fallthrough regular conversion code instead of
22223 extracting the object if converting to a type variant.
22224 (create_var_decl): When a variable has an initializer requiring code
22225 generation and we are at the top level, check for a potential violation
22226 of a No_Elaboration_Code restriction.
22227 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22228 SIZE and SIZE_UNIT which we need for later back-annotations.
22229 * utils.c: (convert) <STRING_CST>: Remove obsolete code.
22230 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
22231 is an unchecked union.
22232 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22233 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22234 main variant, just replace the VIEW_CONVERT_EXPR.

22370 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22371 for task component, in the case of a limited aggregate. The enclosed

22412 with an actual subtype so GIGI can make a correct size computation.
22413 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22414 'Unrestricted_Access, if the designated type is an interface we
22415 add a type conversion to force the displacement of the pointer

22417 Use Universal_Real instead of Long_Long_Float when we need a high
22418 precision float type for the generated code (prevents gratuitous
22419 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22420 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22421 'Terminated for task interface class-wide objects. Generate a call to
22422 the predefined dispatching routine used to retrieve the _task_id from
22423 a task corresponding record.

22449 for any entity whose value is known from the condition of the first
22451 (Expand_N_Return_Statement): When returning a mutable record, convert
22452 the return value into its actual subtype in order to help the backend
22453 to return the actual size instead of the maximum. This is another

22457 handling of error msg for suspicious reverse range iteration.

22483 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

22503 attribute of the N_Free_Statement.
22504 Generate itype for classwide designated object in both cases of

22769 (Build_Derived_Record_Type): Relax the condition that controls the
22770 execution of the check that verifies that the partial view and

22781 Descendant to Find_Ancestor_Interface to leave the code more clear.
22782 Remove wrong code that avoids the generation of an error message
22783 when the immediate ancestor of the partial view is an interface.
22784 In addition some minor reorganization of the code has been done to
22785 leave it more clear.
22786 (Analyze_Type_Declaration): If type has previous incomplete tagged
22787 partial view, inherit properly its primitive operations.

22801 be included in the interface list.
22802 (Access_Definition): If the designated type is an interface that may
22803 contain tasks, create Master_Id for it before analyzing the expression
22804 of the declaration, which may be an allocator.

22839 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22840 not try to rewrite a renamed stream attribute, because the operations
22841 on the type may not have been generated.
22842 Handle properly a renaming_as_body generated for a stream operation
22843 whose default is abstract because the object type itself is abstract.
22844 (Find_Type): If the type is incomplete and appears as the prefix of a
22845 'Class reference, it is tagged, and its list of primitive operations
22846 must be initialized properly.
22847 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22848 private declaration of a parent unit, prior to compiling the private
22849 part of a child unit, find on the scope stack the proper parent entity
22850 on which to link the use clause.
22851 (Note_Redundant_Use): Emit a warning when a redundant use clause is
22853 (Analyze_Object_Renaming): An attribute reference is not a legal object

22873 (Valid_Conversion): If the operand has a single interpretation do not
22874 remove address operations.
22875 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22876 statement to inhibit warning.
22877 (Resolve_Unary_Op): Do not produce a warning when
22878 processing an expression of the form -(A mod B)
22879 Use Universal_Real instead of Long_Long_Float when we need a high

22881 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22882 (Resolve_Concatenation_Arg): Improve error message when argument is an
22883 ambiguous call to a function that returns an array.
22884 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

23826 * checks.adb (Check_Needed): New procedure, deals with removing checks
23827 based on analysis of short-circuited forms. Also generates warnings for
23828 improper use of non-short-circuited forms.

23833 * a-ztexio.adb, a-textio.adb, a-witeio.adb: Replace bad range checks
23836 2005-09-01 Robert Dewar <dewar@adacore.com>
23838 * errout.ads, errout.adb (Fix Error_Msg_F): Fix implementation to meet

23844 (Error_Msg_Warn): New variable for < insertion char.
23845 * prj-nmsc.adb: Implement new errout insertion char < (conditional
23847 (Check_For_Source): Change value of Source_Id only after the current
23848 source has been dealt with.
23850 2005-09-01 Robert Dewar <dewar@adacore.com>
23851 Doug Rupp <rupp@adacore.com>
23853 * exp_attr.adb: Handle vax fpt for 'Valid attribute

23859 Hristian Kirtchev <kirtchev@adacore.com>
23860 Javier Miranda <miranda@adacore.com>
23862 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23863 from object notation, the original node is unanalyzed and carries no
23864 semantic information, so that accessiblity checks must be performed on
23865 the type of the actual itself.
23866 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23867 compatibility with Build_Protected_Sub_Specification.
23868 (Check_Overriding_Inherited_Interfaces): Add suport to handle
23869 overloaded primitives.
23870 (Register_Interface_DT_Entry): Use the new name of the formal
23871 the the calls to Expand_Interface_Thunk
23873 * exp_dbug.ads: Augment comments on encoding of protected types to
23874 include the generation of dispatching subprograms when the type
23875 implements at least one interface.
23877 * lib.ads: Extend information in Load_Stack to include whether a given
23878 load comes from a Limited_With_Clause.
23880 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23881 whether a potential circularity is harmless, because it includes units
23882 loaded through a limited_with clause. Extends previous treatment which
23883 did not handle properly arbitrary combinations of limited and
23884 non-limited clauses.
23886 2005-09-01 Nicolas Setton <setton@adacore.com>
23888 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
23889 to be encoded as typ___XBLU_lowerbound__upperbound instead of
23890 typ___XB_lowerbound__upperbound.
23892 2005-09-01 Thomas Quinot <quinot@adacore.com>
23894 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
23895 dummy access formal for RACW/RAS TypeCode TSS.
23896 (Build_TypeCode_Call): Do not generate dummy null access actual for
23897 calls to the TypeCode TSS.
23899 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23901 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
23902 fully qualified name, to distinguish instances with the same local name.

23915 (Free): New deallocation procedure for filter elements
23916 (Close): Deallocate any existing filter for the concerned connection
23918 2005-09-01 Laurent Pautet <pautet@adacore.com>
23920 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
23921 position set is provided, we compute one in order to reduce the maximum
23922 length of the keys. This computation first selects a character
23923 position between 1 and the minimum length of the keys in order to
23924 avoid reducing one of the keys to an empty string.
23925 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23926 does not converge. The initialization procedure now comes with a
23927 maximum number of iterations such that when exceeded, an exception is
23928 raised in Compute. The user can initialize this ratio to another value
23930 Reformating and updated headers.
23932 2005-09-01 Javier Miranda <miranda@adacore.com>
23934 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
23935 that given an entity T creates and returns an Itype that duplicates the
23936 contents of T. The returned Itype has the null-exclusion
23937 attribute set to True, and its Etype attribute references T
23938 to keep the association between the two entities.
23939 Update copyright notice
23941 * sem_aggr.adb (Check_Can_Never_Be_Null,
23942 Aggregate_Constraint_Checks, Resolve_Aggregate,
23943 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
23945 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

23948 Robert Dewar <dewar@adacore.com>
23949 Hristian Kirtchev <kirtchev@adacore.com>
23951 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
23954 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
23956 Call Set_Result_Definition instead of Set_Subtype_Mark.
23957 (P_Subprogram_Specification): Add parsing of anonymous access result
23958 plus null exclusions. Call Set_Result_Definition instead of
23961 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23962 (P_Access_Type_Definition): Add parsing for an anonymous access result
23963 subtype, plus parsing for null exclusions. Call Set_Result_Definition
23964 instead of Set_Subtype_Mark.
23966 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23967 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
23968 (Result_Definition): New function for N_Function_Specifications.
23969 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
23970 N_Function_Specification.
23971 (Set_Null_Exclusion_Present): Allow this flag for
23972 N_Function_Specification.
23973 (Set_Result_Definition): New procedure for N_Function_Specifications.
23974 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
23975 and N_Function_Specification.
23977 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
23978 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
23979 Add support for LIMITED NEW for Ada 2005 AI-419
23980 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
23981 syntax for anonymous access results.
23982 Replace Subtype_Mark field by Result_Definition in
23983 N_Function_Specification and N_Access_Definition specs.
23984 Add Null_Exclusion_Present to spec of N_Function_Specification.
23985 (Result_Definition): New function for N_Function_Specification and
23986 N_Access_Function_Definition.
23987 (Set_Result_Definition): New procedure for N_Function_Specification and
23988 N_Access_Function_Definition.
23990 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
23991 Result_Definition for cases of N_Access_Function_Definition and
23992 N_Function_Specification.
23993 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
23995 2005-09-01 Vincent Celier <celier@adacore.com>
23997 * lib-writ.adb: Update Copyright notice
23998 (Write_With_Lines): On platforms where file names are case-insensitive,
23999 record the file names in lower case.
24000 (Write_ALI): For D lines, on platforms where file names are
24001 case-insensitive, record the file names in lower case.
24003 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24004 Emmanuel Briot <briot@adacore.com>
24006 * lib-xref.adb (Output_Overridden_Op): Display information on
24007 overridden operation.
24009 * lib-xref.ads: Add documentation on overridden operations.
24011 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
24014 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
24015 overriding entity information.
24017 2005-09-01 Vincent Celier <celier@adacore.com>
24019 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
24020 including those that are inherited.
24022 2005-09-01 Robert Dewar <dewar@adacore.com>
24024 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
24026 * par-prag.adb: Implement new pragma Debug_Policy
24028 * sem_prag.adb Implement new pragma Debug_Policy
24029 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
24030 Component_Size attribute specification. Give warning for ignored pragma
24033 * snames.h, snames.ads, snames.adb: Introduce entries in
24034 Preset_Names for Name_Disp_Asynchronous_Select,
24035 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
24036 Name_Disp_Timed_Select.
24037 New pragma Debug_Policy
24039 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24041 Switch -gnata also sets Debug_Pragmas_Enabled
24043 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24044 handle an explicit -gnata when compiling predefined files.
24046 2005-09-01 Vincent Celier <celier@adacore.com>
24048 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24049 directories of projects that have no Ada sources.
24051 2005-09-01 Robert Dewar <dewar@adacore.com>
24053 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24054 (makes a difference for wide characters)
24056 * widechar.adb, widechar.ads:
24057 Add Wide_Char_Byte_Count feature to count chars vs bytes
24059 2005-09-01 Thomas Quinot <quinot@adacore.com>
24060 Ed Schonberg <schonberg@adacore.com>
24061 Robert Dewar <dewar@adacore.com>
24063 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24064 'Address attribute reference with an overloaded prefix, use the
24065 location of the prefix (not the location of the attribute reference) as
24066 the error location.
24067 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24068 a function renaming thereof, is a valid prefix for 'Size (where it is
24069 intepreted as a function call).
24070 (Statically_Denotes_Entity): New predicate to determine whether the
24071 prefix of an array attribute can be considered static.
24074 (Eval_Attr): Fix failure to evaluate Component_Size for
24075 unconstrained arrays (resulted in wrong value in packed case, since
24076 back end cannot handle this case)
24078 2005-09-01 Robert Dewar <dewar@adacore.com>
24080 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
24081 error msgs for most common cases.
24082 Use new errout insertion char < (conditional warning)
24084 2005-09-01 Javier Miranda <miranda@adacore.com>
24085 Ed Schonberg <schonberg@adacore.com>
24087 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24088 become local to the whole package.
24089 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24090 the package was already analyzed the new algorithm "replaces" the
24091 real entities by the shadow ones. This is required to ensure that
24092 the order of these entities in the homonym chains does not change;
24093 otherwise we can have undefined references at linking time because
24094 in case of conflicts the external name of the entities will have
24095 a suffix that depends on the order of the entities in the chain.
24096 (Remove_Limited_With_Clause): Complementary code that completes the
24097 new algorithm and replaces the shadow entities by the real ones.
24098 (Install_Limited_Withed_Unit): When unchaining entities before the
24099 installation of the shadow entities, only regular entities of the
24100 public part must be taken into account. This is required to
24101 keep this routine in synch with the work done by Remove_Limited_
24103 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24104 even if unit is analyzed, because the analysis of the unit is
24105 idempotent in any case, and the limited view of the unit may have to
24106 be installed for proper visibility.
24107 (Expand_Limited_With_Clause): Even if the unit in the implicit
24108 with_clause has been analyzed already, a limited view of the package
24109 must be built for the current context, if it does not exist yet.
24111 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24112 Javier Miranda <miranda@adacore.com>
24113 Gary Dismukes <dismukes@adacore.com>
24115 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24116 defining entity for the instance body, make a new defining identifier
24117 rather than copying the entity of the spec, to prevent accidental
24118 sharing of the entity list.
24119 (Check_Private_View): When exchanging views of private types, build the
24120 list of exchanged views as a stack, to ensure that on exit the exchanges
24121 are undone in the proper order.
24122 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24123 Restore the compilation environment in case of instantiation_error.
24124 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24125 for an anonymous access result.
24126 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24127 (Formal_Entity): Handle properly the case of a formal package that
24128 denotes a generic package renaming.
24130 2005-09-01 Thomas Quinot <quinot@adacore.com>
24132 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24133 clause if the array aggregate is surrounded by parentheses.
24135 2005-09-01 Cyrille Comar <comar@adacore.com>
24136 Gary Dismukes <dismukes@adacore.com>
24137 Ed Schonberg <schonberg@adacore.com>
24138 Javier Miranda <miranda@adacore.com>
24140 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24142 to check if a type is Constrained in cases related to code generation
24143 (rather than semantic checking) since otherwise we do not generate
24144 similar code for mutable private types depending if their
24145 discriminants are visible or not.
24146 (Check_Abstract_Overriding): Do not complain about failure to override
24147 the primitive operations used in dispatching selects since they will
24148 always be overriden at the freeze point of the type.
24149 (Access_Definition): Separate out handling for resetting the scope
24150 of an anonymous access function result type. Retrieve the scope
24151 of the associated function rather than using Current_Scope, which
24152 does not have a consistent value (depends on whether we're in the
24153 middle of analyzing formal parameters). Add ??? comment about
24154 finding a cleaner way to handle the special cases of scope setting.
24155 (Process_Incomplete_Dependents): A protected operation is never a
24156 dispatching operation (only its wrapper may be).
24157 (Build_Derived_Record_Type): In case of tagged private types that
24158 implement interfaces add derivation of predefined primitive
24160 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24161 by two parameters that are used in case of derivation from abstract
24162 interface types: No_Predefined_Prims is used to avoid the derivation
24163 of predefined primitives from the interface, and Predefined
24164 Prims_Only is used to complete the derivation predefined primitives
24165 in case of private tagged types implementing interfaces.
24166 Fix typo in comments
24167 (Find_Interface_In_Descendant): Protect the frontend against
24168 wrong code with large circularity chains.
24169 (Is_Private_Overriding): Add support for entities overriding interface
24170 subprograms. The test failed because Entities associated with overriden
24171 interface subprograms are always marked as hidden (and used to build
24172 the secondary dispatch table); in this case the overriden entity is
24173 available through the field abstract_interface_alias (cf. override_
24174 dispatching_operation)
24175 (Access_Definition): Set the scope of the type to Current_Scope for the
24176 case of a function with an anonymous access result type.
24177 (Access_Subprogram_Declaration): Handle creation of the type entity for
24178 an access-to-function type with an anonymous access result.
24179 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24180 in handling for N_Access_Function_Definition.
24181 (Analyze_Subtype_Declaration): Modify the text of error message.
24182 (Derived_Type_Declaration): Modify the text of error message.
24183 (Process_Subtype): Modify the text of error message plus cleanup
24184 of one redundant error message.
24185 (Analyze_Component_Declaration): Code cleanup.
24186 (Analyze_Object_Declaration): Code cleanup.
24187 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24188 attribute in case of access types. Code cleanup.
24189 (Array_Type_Declaration): Code cleanup.
24190 (Process_Discriminants): Create the new null-excluding itype
24191 if required. Code cleanup.
24192 (Process_Subtype): Create the new null-excluding itype if
24193 required. Code cleanup.
24194 (Build_Derived_Record_Type): Code cleanup to avoid calling
24195 twice the subprogram derive_subprograms in case of private
24196 types that implement interfaces. In this particular case the
24197 subprogram Complete_Subprograms_Derivation already does the
24198 job associated with the second call.
24200 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24201 conversion to the full view when generating an operation for a
24202 discriminant whose type may currently be private.
24204 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24205 Javier Miranda <miranda@adacore.com>
24207 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24208 V (Obj.F), the rewriting does not involve the indexed component, but
24209 only the selected component itself.
24210 Do not apply the transformation if the analyzed node is an actual of a
24211 call to another subprogram.
24212 (Complete_Object_Operation): Retain the entity of the
24213 dispatching operation in the selector of the rewritten node. The
24214 entity will be used in the expansion of dispatching selects.
24215 (Analyze_One_Call): Improve location of the error message associated
24217 (Analyze_Selected_Component): No need to resolve prefix when it is a
24218 function call, resolution is done when parent node is resolved, as
24220 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24221 when attempting to resolve a call transformed from its object notation.
24222 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24223 of the argument list for each interpretation of the operation.
24224 (Try_Object_Operation): The designated type of an access parameter may
24225 be an incomplete type obtained through a limited_with clause, in which
24226 case the primitive operations of the type are retrieved from its full
24228 (Analyze_Call): If this is an indirect call, and the return type of the
24229 access_to_subprogram is incomplete, use its full view if available.
24231 2005-09-01 Javier Miranda <miranda@adacore.com>
24232 Gary Dismukes <dismukes@adacore.com>
24234 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24235 access types the null-exclusion and access-to-constant attributes must
24237 (Analyze_Return_Statement): When the result type is an anonymous access
24238 type, apply a conversion of the return expression to the access type
24239 to ensure that appropriate accessibility checks are performed.
24240 (Analyze_Return_Type): For the case of an anonymous access result type,
24241 generate the Itype and set Is_Local_Anonymous_Access on the type.
24242 Add ??? placeholder for check to disallow returning a limited object
24243 in Ada 2005 unless it's an aggregate or a result of a function call.
24244 Change calls from Subtype_Mark to Result_Definition.
24245 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24246 Result_Definition in call to Make_Function_Specification.
24247 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24248 Set_Result_Definition.
24249 (Make_Inequality_Operator): Change formal Subtype_Mark to
24250 Result_Definition in call to Make_Function_Specification.
24251 (Process_Formals): Create the new null-excluding itype if required.
24252 (New_Overloaded_Entity): For an entity overriding an interface primitive
24253 check if the entity also covers other abstract subprograms in the same
24254 scope. This is required to handle the general case, that is, overriding
24255 other interface primitives and overriding abstract subprograms inherited
24256 from some abstract ancestor type.
24257 (New_Overloaded_Entity): For an overriding entity that comes from
24258 source, note the operation that it overrides.
24259 (Check_Conformance, Type_Conformant): Addition of one new formal
24260 to skip controlling formals in the analysis. This is used to
24261 handle overloading of abstract interfaces.
24262 (Base_Types_Match): Add missing case for types imported from
24263 limited-with clauses
24264 (New_Overloaded_Entity): Add barrier to protect the use of
24265 the "alias" attribute.
24267 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24269 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24270 verify that the procedure and the entry are mode conformant.
24271 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24272 as a different operator, which is often a cut-and-paste error.
24274 2005-09-01 Javier Miranda <miranda@adacore.com>
24275 Ed Schonberg <schonberg@adacore.com>
24277 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24278 used in controlling parameters exclude null because it is necessary to
24279 read the tag to dispatch, and null has no tag.
24280 (Override_Dispatching_Operation): If the previous operation is inherited
24281 from an interface, it becomes hidden and does not participate in later
24284 2005-09-01 Javier Miranda <miranda@adacore.com>
24285 Ed Schonberg <schonberg@adacore.com>
24286 Gary Dismukes <dismukes@adacore.com>
24288 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24289 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24290 the expander will generate the corresponding run-time check to evaluate
24292 (Resolve_Call): Check for legal type of procedure name or prefix that
24293 appears as a trigger in a triggering alternative.
24294 (Valid_Conversion): If expression is ambiguous and the context involves
24295 an extension of System, remove System.Address interpretations.
24296 (Resolve_Qualified_Expression): Reject the case of a specific-type
24297 qualification applied to a class-wide argument. Enhance comment
24298 to explain checking of Original_Node.
24299 (Resolve_Type_Conversion): The location of the error message was not
24300 general enough to handle the general case and hence it has been removed.
24301 In addition, this patch improves the text of the message.
24302 (Resolve_Type_Conversion): Add missing support for access to interface
24304 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24305 do not expand if the expression is the actual in a call, because proper
24306 expansion will take place when the call itself is expanded.
24307 (Resolve_Allocator): If the context is an unchecked conversion, the
24308 allocator inherits its storage pool, if any, from the target type of
24311 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24312 Javier Miranda <miranda@adacore.com>
24314 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24315 inherited interface operation that has an implementation, use the
24316 implementation to avoid spurious ambiguities.
24317 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24318 use the Corresponding_Record_Typ attribute to look for the interface
24319 because it is set by the expander (and hence it is not always
24320 available). For this reason we traverse the list of interfaces
24321 (available in the parent of the concurrent type).
24322 (Interface_Present_In_Ancestor): Handle entities from the limited view
24324 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24326 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24327 from the list of required components.
24328 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24329 primitive procedure of a limited interface with a controlling first
24331 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24333 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24334 capture if it is generated in the second operand of a short-circuit
24336 Do not capture values for variables with address clauses.
24337 (Is_Object_Reference): Treat a function call as an object reference only
24338 if its type is not Standard_Void_Type.
24340 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24342 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24343 to a variable that is statically known to be constant.

24360 Document new treatment of wide characters in max line length
24362 Remove -gnatL/-gnatZ switches, no longer used.
24363 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24366 * gnat_rm.texi: Add doc for two argument form of pragma
24367 Float_Representation.
24368 Add documentation for pragma No_Strict_Aliasing
24369 Add note that explicit component clause overrides pragma Pack.

24566 view of the type to resolve the case alternatives.

24602 _withed_unit that checks if some package installed through normal with
24603 clauses has a renaming declaration of package whose limited-view is

24605 of the current Draft document for Ada 2005.
24606 (Analyze_Context): Complete the list of compilation units that
24607 are allowed to contain limited-with clauses. It also contains
24608 checks that were previously done by Install_Limited_Context_Clauses.

25125 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25126 longer protected objects. They have been replaced by lower-level
25127 suspension objects made up by a mutex and a condition variable (or
25128 their equivalent given a particular OS) plus some internal data to
25129 reflect the state of the suspension object.
25130 (Initialize, Finalize): Add this initialization procedure for
25131 Suspension_Object, which is a controlled type.
25132 (Finalize): Add the finalization procedure for Suspension_Object,
25133 which is a controlled type.
25135 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

25158 object to True, releasing the task that was suspended, if any.
25159 (Suspend_Until_True): Add this procedure that blocks the calling task
25160 until the state of the object is True. Program_Error is raised if
25161 another task is already waiting on that suspension object.
25162 (Initialize): Add this procedure for initializing the suspension
25163 object. It initializes the mutex and the condition variable which are
25164 used for synchronization and queuing, and it sets the internal state
25166 (Finalize): Add this procedure for finalizing the suspension object,
25167 destroying the mutex and the condition variable.

25173 which provides a low-level abstraction (using operating system
25174 primitives) for Ada.Synchronous_Task_Control.
25175 This object is made up by a mutex (for ensuring mutual exclusion), a
25176 condition variable (for queuing threads until the condition is
25177 signaled), a Boolean (State) indicating whether the object is open,
25178 and a Boolean (Waiting) reflecting whether there is a task already

25393 within gdb to display the dispatch tables associated with a tagged
25395 (Collect_All_Interfaces): New subprogram that collects the whole list
25396 of interfaces that are directly or indirectly implemented by a tagged
25398 (Default_Prim_Op_Position): New subprogram that returns the fixed
25399 position in the dispatch table of the default primitive operations.
25400 (Expand_Interface_Actuals): New subprogram to generate code that
25401 displaces all the actuals corresponding to class-wide interfaces to
25402 reference the interface tag of the actual object.
25403 (Expand_Interface_Conversion): New subprogram. Reference the base of
25404 the object to give access to the interface tag associated with the
25405 secondary dispatch table.
25406 (Expand_Interface_Thunk): New subprogram that generates the code of the
25407 thunk. This is required for compatibility with the C+ ABI.
25408 (Make_Abstract_Interface_DT): New subprogram that generate the
25409 declarations for the secondary dispatch tables associated with an
25410 abstract interface.
25411 (Set_All_Interfaces_DTC_Entity): New subprogram that sets the DTC_Entity

25618 Prevent the special checks for conversions of access discriminants in
25619 the case where the discriminant belongs to a nonlimited type, since
25620 such discriminants have their accessibility level defined in the same
25621 way as a normal component of an anonymous access type.
25622 (Resolve_Allocator): When an allocator's designated type is a class-wide
25623 type, check that the accessibility level of type given in the
25624 allocator's expression or subtype indication is not statically deeper

25644 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25645 check on possible violation of restriction No_Direct_Boolean_Operators

25857 Factor common code across the stream-oriented attribute circcuits into
25858 a new subprogram, Analyze_Stream_TSS_Definition. The new uniform
25859 processing is functionally identical to the previous duplicated one,

26603 (check dos line terminator).
26604 (Check_Line_Max_Length): New procedure, split off from the existing
26605 Check_Line_Terminator routine. Separating this out allows -gnatyf to
26606 be properly recognized.
26608 * styleg.adb: Add ??? comment for line terminator reference
26610 * scng.adb (Check_End_Of_Line): Fix bug of -gnatyf being ignored

26649 2005-03-29 Thomas Quinot <quinot@adacore.com>
26651 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26652 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26653 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26654 analyzed if expansion is disabled (which could otherwise cause spurious
26655 error messages if expansion has been disabled due to previous
26656 (unrelated) errors).
26658 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26659 is disabled, the entity denoted by the argument is the access type
26660 itself, not an underlying record type, so there is no need to go back
26661 to the Corresponding_Remote_Type.
26663 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26664 Robert Dewar <dewar@adacore.com>
26666 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
26667 expand a call to an instance of
26668 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
26669 Constructor actual of the instance. A class-wide membership
26670 check is also generated, to ensure that the tag passed to the instance
26671 denotes a type in the class.
26672 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26673 of Name_Generic_Dispatching_Constructor.
26675 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26676 05 unit for AI-260-02).
26678 * a-tgdico.ads: New file.
26680 * impunit.adb (Non_Imp_File_Names_05): Add entry "a-tgdico" for new

26688 character type cases.
26689 (Analyze_Subprogram_Renaming): Add special handling for
26690 the case of renaming of stream attributes when the renaming denotes a
26691 generic formal subprogram association for an abstract formal subprogram.
26692 Check that the attribute is a primitive stream attribute (and not
26693 a class-wide stream attribute) and then rewrite the attribute name
26694 as the name of the appropriate compiler-generated stream primitive.
26696 2005-03-29 Robert Dewar <dewar@adacore.com>
26698 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to
26700 (Is_Possibly_Unaligned_Object): Correct typo that
26701 resulted in inaccurate result for unaligned scalars within records.
26703 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26705 * freeze.adb (Freeze_Record_Type): If the type of the component is an
26706 itype whose parent is controlled and not yet frozen, do not create a
26707 freeze node for the itype if expansion is disabled.
26709 2005-03-29 Vincent Celier <celier@adacore.com>
26711 * make.adb (Gnatmake): Don't fail if the main project file is declared
26712 as having no Ada sources. Do not display message "no sources to
26713 compile" in quiet output.
26715 2005-03-29 Doug Rupp <rupp@adacore.com>
26717 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26722 * par-ch12.adb (P_Generic): Give better msg for illegal private generic
26725 2005-03-29 Robert Dewar <dewar@adacore.com>
26727 * par-ch3.adb (P_Type_Declaration): Fix bad error recovery after
26728 missing TYPE Improve the error message generated when compiling a
26729 limited interface in Ada83 or Ada95 mode.
26731 2005-03-29 Robert Dewar <dewar@adacore.com>
26733 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26734 rather than proceed ahead using a junk attribute name.
26736 2005-03-29 Vincent Celier <celier@adacore.com>
26738 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26740 * prj-part.adb (Parse_Single_Project): Set the location of a project
26741 on its defining identifier, rather than on the reserved word "project".
26743 * prj-proc.adb (Expression): Adapt to the fact that default of external
26744 references may be string expressions, not always literal strings.
26745 (Recursive_Process): Set Display_Name equal to Name
26746 when Location is No_Location, that is when there is no actual file.
26747 Get the Display_Name of the project from the source, when it is not a
26749 (Process): Use the Display_Name in error messages
26751 * prj-strt.adb (External_Reference): Allow default to be string
26752 expressions, not only literal strings.
26754 2005-03-29 Vincent Celier <celier@adacore.com>
26756 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
26757 file and the reference symbol file to be the same file.
26759 2005-03-29 Thomas Quinot <quinot@adacore.com>
26761 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
26762 forbid conversion of a local access-to-subprogram type to a remote one.
26764 * sem_util.adb (Wrong_Type): For a record type that is the expanded
26765 equivalent type for a remote access-to-subprogram type, go back to the
26766 original RAS entity when displaying an error message, so the casing is
26767 the original source casing.
26769 2005-03-29 Robert Dewar <dewar@adacore.com>
26771 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
26774 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26776 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26777 subtype if code is being pre-analyzed, to prevent un-expanded
26778 references to protected formals, among others.
26779 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26780 interpretation that can be a call, include the result of the call as a
26781 possible interpretation of the dereference.
26783 * sem_ch5.adb (Process_Bounds): Determine type of range by
26784 pre-analyzing a copy of the original range, and then analyze the range
26785 with the expected type.
26787 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26788 with an overloaded prefix where not all interpretations yield an
26789 access to subprogram, do not rewrite node as a call.
26790 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26791 the node as a call once the context identifies the interpretation of
26792 the prefix whose call yields the context type.
26793 (Valid_Conversion): For the case of a conversion between
26794 local access-to-subprogram types, check subtype conformance using
26795 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26796 detailed error message.
26798 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26800 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26801 indicator, indicate that the formal can never be null.
26802 (Process_Formals): If a formal has a non_null indicator, insert the
26803 resulting subtype immediately before the enclosing subprogram decl,
26804 and not at the beginning of the corresponding declarative part, to
26805 prevent access before elaboration (Ada2005).
26807 2005-03-29 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26810 * utils.c (finish_record_type): Use variable_size when setting sizes.
26812 2005-03-29 Robert Dewar <dewar@adacore.com>
26814 * xtreeprs.adb, xnmake.adb: Use Stream_IO instead of Text_IO to
26815 guarantee Unix style line terminators for the output files, even when
26816 running on windows.
26818 2005-03-29 Robert Dewar <dewar@adacore.com>
26820 * a-direct.ads, a-direct.adb (Start_Search): Free allocated search
26821 buffer if an exception is raised.
26823 2005-03-29 Ed Falis <falis@adacore.com>

27303 * makegpr.adb (Project_Tree): New constant needed to use project
27306 2005-03-15 Olivier Hainque <hainque@adacore.com>
27308 * s-intman-posix.adb (Notify_Exception): Adjust signature, as handler
27309 for sigactions with SA_SIGINFO set. Call
27310 __gnat_adjust_context_for_raise before raising, to perform the
27311 potentially required adjustments to the machine context for the GCC
27314 * raise.h (__gnat_adjust_context_for_raise): New prototype.
27316 * init.c (__gnat_adjust_context_for_raise) HPUX: Initial revision.
27317 Adjust PC by one in the provided machine context.
27318 (__gnat_install_handler) HPUX: Set SA_SIGINFO in the sigaction flags,
27319 so that the handler is passed the context structure to adjust prior to
27321 (__gnat_error_handler) HPUX: Adjust the signature to match what an
27322 SA_SIGINFO sigaction should look like. Call
27323 __gnat_adjust_context_for_raise before actually raising.
27324 (__gnat_adjust_context_for_raise): Default noop to help PC
27325 adjustments before raise from signal handlers.
27326 (__gnat_error_handler): Indirectly call a predicate function to
27327 determine if a condition should be resignaled or not.
27328 (__gnat_set_resignal_predicate): User interface to modify the predicate.

27351 * a-retide.ads: Minor comment changes
27353 2005-03-15 Robert Dewar <dewar@adacore.com>
27355 * a-stzunb.adb, a-stzunb.adb a-stzunb.ads, a-stzunb.ads,
27356 a-stwiun.ads, a-stwiun.adb, a-strunb.ads, a-strunb.adb: Move
27357 Realloc_For_Chunk to private part of package.
27358 New subprograms for AI-301
27360 * a-szuzti.adb, a-suteio.adb, a-swuwti.adb: Improve efficiency of
27361 Get_Line procedure.
27362 Avoid unnecessary use of Get/Set_Wide_String
27364 2005-03-15 Robert Dewar <dewar@adacore.com>
27367 * a-stunau.ads, a-stunau.adb:
27368 Change interface to allow efficient (and correct) implementation
27369 The previous changes to allow extra space in unbounded strings had
27370 left this interface a bit broken.
27372 * a-suteio.adb: Avoid unnecessary use of Get/Set_String
27374 * g-spipat.ads, g-spipat.adb: New interface for Get_String
27375 Minor reformatting (function specs)
27377 * g-spitbo.adb: New interface for Get_String
27379 * g-spitbo.ads: Minor reformatting
27381 * a-swunau.ads, a-swunau.adb: New interface for Get_Wide_String
27383 * a-szunau.ads, a-szunau.adb: New interface for Get_Wide_Wide_String
27385 2005-03-15 Javier Miranda <miranda@adacore.com>
27386 Robert Dewar <dewar@adacore.com>
27387 Thomas Quinot <quinot@adacore.com>
27388 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27390 * atree.ads, atree.adb: Add support for Elist24 field
27392 * atree.h: Fix wrong definition of Field27
27393 Add support for Elist16 field
27394 Add support for Elist24 field
27396 * einfo.ads, einfo.adb (Abstract_Interfaces,
27397 Set_Abstract_Interfaces): New subprograms.
27398 (Abstract_Interface_Alias, Set_Abstract_Interface_Alias): New
27400 (Access_Disp_Table, Set_Access_Disp_Table): Modified to handle a list of

27409 (Set_Task_Body_Procedure): New subprogram to set this attribute.
27410 (Has_Controlled_Component): Now applies to all entities.
27411 This is only a documentation change, since it always worked to apply
27412 this to other than composite types (yielding false), but now this is
27414 Update documentation on Must_Be_Byte_Aligned for new spec
27416 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
27417 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
27418 uses of the Access_Disp_Table attribute to reference the first dispatch
27419 table associated with a tagged type. As
27420 part of the implementation of abstract interface types,
27421 Access_Disp_Table has been redefined to contain a list of dispatch
27422 tables (rather than a single dispatch table).
27423 Similarly, upgrade all the references to Tag_Component by the
27424 new attribute First_Tag_Component.
27425 (Find_Inherited_TSS): Moved to exp_tss.
27426 Clean up test in Expand_N_Object_Declaration for cases
27427 where we need to do a separate assignment of the initial value.
27428 (Expand_N_Object_Declaration): If the expression in the
27429 declaration of a tagged type is an aggregate, no need to generate an
27430 additional tag assignment.
27431 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
27433 Bit packed array ops are only called if operands are known to be
27435 (Component_Equality): When returning an N_Raise_Program_Error statement,
27436 ensure that its Etype is set to Empty to avoid confusing GIGI (which
27437 expects that only expressions have a bona fide type).
27438 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
27439 determine the amount of data to be copied.
27441 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
27442 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
27443 INTERFACE_TYPE_DEFINITION ::=
27444 [limited | task | protected | synchronized] interface
27445 [AND interface_list]
27447 * par-ch3.adb (P_Type_Declaration): Modified to give support to
27449 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
27451 (P_Interface_Type_Definition): New subprogram that parses the new
27452 syntax rule of Ada 2005 interfaces
27453 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
27454 messages by the correct RENAMES (quotes removed).
27456 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
27457 attribute First_Tag_Component.
27459 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
27460 (Interface_List, Set_Interface_List): New subprograms.
27461 (Interface_Present, Set_Interface_Present): New subprograms.
27462 (Limited_Present, Set_Limited_Present): Available also in derived
27463 type definition nodes.
27464 (Protected_Present, Set_Protected_Present): Available also in
27465 record type definition and
27466 derived type definition nodes.
27467 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
27468 (Task_Present, Set_Task_Present): New subprogram.
27469 (Task_Body_Procedure): Removed.
27470 (Set_Task_Body_Procedure): Removed.
27471 These subprogram have been removed because the attribute
27472 Task_Body_Procedure has been moved to the corresponding task type
27473 or task subtype entity to leave a field free to store the list
27474 of interfaces implemented by a task (for AI-345)
27475 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27476 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27477 expression flag Do_Range_Check
27478 (Exception_Junk): Change to Flag7 to accomodate above change
27479 (Box_Present, Default_Name, Specification, Set_Box_Present,
27480 Set_Default_Name, Set_Specification): Expand the expression
27481 "X in N_Formal_Subprogram_Declaration" into the corresponding
27482 two comparisons. Required to use the csinfo tool.
27484 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
27485 "with string" given.
27487 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
27490 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
27493 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27494 attribute Task_Body_Procedure rather than the old semantic field that
27495 was available in the task_type_declaration node.
27497 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27498 interface type definitions.
27499 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27502 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
27503 task type declaration.
27504 (P_Protected): Modified to handle the list of interfaces in a
27505 protected type declaration.
27507 2005-03-15 Doug Rupp <rupp@adacore.com>
27508 Vincent Celier <celier@adacore.com>
27510 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27511 (Gen_Output_File_C): Likewise.
27512 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
27514 2005-03-15 Thomas Quinot <quinot@adacore.com>
27516 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27517 is an N_Raise_Constraint_Error node, create a new copy of it without
27518 going through a call to Duplicate_Subexpr.
27520 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
27521 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27522 Nicolas Setton <setton@adacore.com>
27523 Ed Schonberg <schonberg@adacore.com>
27529 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27530 representation clause that prescribes a size not equal to the rounded
27531 size of their types.
27532 (gnat_to_gnu_entity, case E_Component): Always look at
27533 Original_Record_Component if Present and not the entity.
27534 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27535 of tagged extension types by not making field for components that are
27537 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27538 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27539 expression to the type of the object when the object is constant.
27540 Reverse defer_debug_incomplete_list before traversing it, so that trees
27541 are processed in the order at which they were added to the list. This
27542 order is important when using the stabs debug format.
27543 If we are deferring the output of debug information, also defer this
27544 output for a function return type.
27545 When adding fields to a record, prevent emitting debug information
27546 for incomplete records, emit the information only when the record is
27548 (components_to_record): New parameter defer_debug.
27549 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27550 (gnat_to_gnu_field_decl): New function.
27551 (substitution_list, annotate_rep): Call it.
27552 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27553 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27554 No longer update discriminants to not be a COMPONENT_REF.
27555 (copy_alias_set): Strip padding from input type; also handle
27556 unconstrained arrays properly.
27558 * gigi.h (write_record_type_debug_info): New function.
27559 Convert to use ANSI-style prototypes. Remove unused
27560 declarations for emit_stack_check, elab_all_gnat and
27561 set_second_error_entity.
27562 (gnat_to_gnu_field_decl): New decl.
27564 * utils.c (write_record_type_debug_info): New function.
27565 (finish_record_type): Delegate generation of debug information to

27567 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27568 (update_pointer_to): Fix pasto.
27569 (convert) <UNION_TYPE>: Accept slight type variations when
27570 converting to an unchecked union type.
27572 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27573 replace the N_Freeze_Entity with a null statement.
27575 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27576 within a constrained subcomponent of an enclosing record, place the
27577 freeze nodes in the scope stack entry for the enclosing record.
27578 (Undelay_Type): New Subprogram.
27579 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27580 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27581 within records; allow them to have freeze nodes if their base types
27584 * exp_util.adb (Remove_Side_Effects): Properly test for
27585 Expansion_Delayed and handle case when it's inside an
27586 N_Qualified_Expression.
27588 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27589 Comes_From_Generic, to recognize accurately that the parent type in a
27590 derived type declaration can be traced back to a formal type, because
27591 it is one or is derived from one, or because its completion is derived
27593 (Constrain_Component_Type): If component comes from source and has no
27594 explicit constraint, no need to constrain in in a subtype of the
27596 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27597 Minor change to propagate Is_Ada_2005 flag
27599 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27600 Expansion_Delayed is False.
27601 (assoc_to_constructor): Ignore fields that have a
27602 Corresponding_Discriminant.
27603 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27604 function returns "by target", dereference the target pointer using the
27605 type of the actual return value.
27606 <all>: Be prepared for a null gnu_result.
27607 (processed_inline_subprograms): Check flag_really_no_inline
27608 instead of flag_no_inline.
27609 (set_second_error_entity): Remove unused function.
27610 (gnat_to_gnu, case N_Selected_Component): Call
27611 gnat_to_gnu_field_decl.

27614 2005-03-15 Robert Dewar <dewar@adacore.com>
27615 Ed Schonberg <schonberg@adacore.com>
27616 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27618 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27619 Must_Be_Byte_Aligned for cases where we do not need to use a
27620 System.Pack_nn unit.
27622 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27624 Needed now that we do some processing for IN parameters as well. This
27625 may well fix some unrelated errors.
27626 (Expand_Call): Handle case of unaligned objects (in particular those
27627 that come from packed arrays).
27628 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27629 renamed entity is an inherited operation, re-expand the call using the
27630 original operation, which is the one to call.
27631 Detect attempt to inline parameterless recursive subprogram.
27632 (Represented_As_Scalar): Fix to work properly with private types
27633 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27634 accurate estimate. Yields True in far fewer cases than before,
27635 improving the quality of code that depends on this test.
27637 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27638 over both visible and private declarations to remove them from tree,
27639 and mark subprograms declared in package as eliminated, to prevent
27640 spurious use in subsequent compilation of generic units in the context.
27642 * exp_util.ads: Minor cleanup in variable names
27644 * sem_eval.ads, sem_eval.adb: Minor reformatting
27645 (Compile_Time_Known_Bounds): New function
27647 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27649 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27650 determining whether an unchecked conversion is needed for the argument
27651 of an initialization call.
27653 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27655 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27656 that appears in the instantiation rather than the internal subtype
27657 generated in the wrapper package, to avoid anomalies in gigi when the
27658 target is derived from a private type whose full view is an access type.
27660 2005-03-15 Robert Dewar <dewar@adacore.com>
27662 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27664 Add documentation to replace the use of this flag
27665 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27668 2005-03-15 Thomas Quinot <quinot@adacore.com>
27670 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27671 here from exp_attr so it can be shared between exp_attr and exp_dist.
27672 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27673 all TSS names, not a subset thereof, and the previous name introduced
27674 an unnecessarily confusion that a distinction might exist between
27675 "OK" TSS names and some "not OK" TSS names.
27677 2005-03-15 Doug Rupp <rupp@adacore.com>
27679 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27682 2005-03-15 Pascal Obry <obry@adacore.com>
27683 Eric Botcazou <ebotcazou@adacore.com>
27687 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27688 when IN_RTS. This is to work around a bootstrap path problem.
27690 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27691 table and pass it to __gnat_install_SEH_handler().
27692 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27694 * lang.opt: Fix specification of -fRTS=.
27696 2005-03-15 Doug Rupp <rupp@adacore.com>
27697 Bernard Banner <banner@adacore.com>
27698 Vincent Celier <celier@adacore.com>
27699 Arnaud Charlet <charlet@adacore.com>
27702 This change works fine when gnatlib is built from the gcc directory,
27703 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27704 is not passed to ada/Makefile.in, so more work is needed by a
27705 Makefile/configure expert.
27707 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27708 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27709 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27711 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27712 Run ranlib on libgccprefix.a
27713 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27714 (ADA_INCLUDE_SRCS): Split Ada packages.
27716 2005-03-15 Robert Dewar <dewar@adacore.com>
27718 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27720 * impunit.adb: Add GNAT.UTF_32
27722 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27724 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27725 now uses GNAT.UTF_32).
27727 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27728 capabilities for categorizing characters using Unicode categories
27730 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27732 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27733 instantiation that has been rewritten as a package body, retrieve spec
27734 to generate proper name for implicit_with_clause.
27735 (Install_Parents): Recognize a parent that is an instantiation but has
27736 been rewritten as a package declaration during analysis.
27738 2005-03-15 Javier Miranda <miranda@adacore.com>
27739 Ed Schonberg <schonberg@adacore.com>
27741 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27742 parameter reported some error we immediately return. This improves the
27743 behaviour of the frontend in case of errors.
27744 (Install_Parent, Remove_Parent): Introduce new flag
27745 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27746 ancestor of a generic child unit, when the child is being instantiated.
27747 (Inline_Instance_Body): If we are compiling the private
27748 part or the body of a child unit, restore the proper visibility of the
27749 parents after compiling the instance body.
27751 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27752 Javier Miranda <miranda@adacore.com>
27755 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27756 of a private type, in which case it is underlying_type that denotes
27757 the proper task. Also modified to use the new entity attribute
27758 that is directly available in the task type and task subtype entities
27759 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27760 arrays when other dimensions than the first are constrained by
27761 discriminants of an enclosing record.
27762 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27763 a combination of indexed and selected components, find ultimate entity
27764 and generate the appropriate reference for it, to suppress spurious
27766 (Note_Possible_Modification): If an entity name has no entity, return.
27767 (Is_Variable): A function call never denotes a variable.
27768 (Requires_Transient_Scope): For record types, recurse only on
27769 components, not on internal subtypes that may have been generated for
27770 constrained components.
27772 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27774 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27775 Eliminated as candidates for resolution. Both efficient, and avoids
27776 anomalies with operators declared in deleted code.
27777 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27778 expansion is disabled (as when compiling a generic) to prevent spurious
27779 warnings on prefixes of selected components.
27781 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27783 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27784 attached to a list before checking whether it appears in the private

28267 (Get_TSD): Modified to access the new position of the TSD.
28268 (Set_TSD): Modified to save the TSD in its new position.
28270 * par-ch12.adb (P_Formal_Subprogram_Declaration): Add parsing for the
28271 case of formal abstract subprograms. Add check and message for -gnat05.
28274 * sem_ch12.adb: Add with and use for Sem_Disp.
28275 (Analyze_Associations): Minor change from "=" to "in" for use of
28276 N_Formal_Subtype_Declaration (which is now a subtype).
28277 (Set_Analyzed_Formal): Minor changes from "=" to "in" for uses of
28278 N_Formal_Subtype_Declaration (which is now a subtype).
28279 (Analyze_Formal_Subprogram): Add handling for
28280 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28281 dispatching, setting the controlling status of the formal parameters
28282 and result, and issuing an error if there is no controlling type for
28283 the formal subprogram.
28284 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28285 which is an unclean use of that field, we set the new field
28286 Corresponding_Formal_Spec to make the formal subprogram available to
28287 processing in Analyze_Subprogram_Declaration.
28288 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28289 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
28290 Constrained, so that it is is does not statically match its anonymous
28293 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
28294 abstract formal subprograms in error check for functions returning
28295 abstract types. Set scope of new designator for
28296 a parameterless subprogram, so that it is available when checking the
28297 body for nested subprograms, before full analysis of said body.
28298 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28299 subprogram only if inner one comes from source.
28300 (Analyze_Function_Call): If the call is given in object notation, the
28301 analysis of the name rewrites the node and analyzes it with the proper
28302 argument list. After analyzing the name, if the call has been rewritten
28303 and the result type is set, no further analysis is needed.
28304 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28305 mark in function specification, in a context where the formals are
28306 visible and hide outer homographs.
28308 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28309 as the tagged type for the cases of abstract formal subprograms and
28310 renamings of those. Clean up spec comments.
28311 (Check_Dispatching_Context): Add error message to indicate "abstract
28312 procedure", covering the case of a call to a formal abstract procedure
28313 that has statically tagged operands.
28314 (Check_Dispatching_Call): Check for the case of an actual given by
28315 a tag-indeterminate function call whose type is an ancestor of the
28316 containing call's associated tagged type. This situation can occur
28317 for inherited primitives with function defaults. In this case we
28318 use the tagged type's tag directly as the controlling argument for
28320 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28322 * sprint.adb (Sprint_Node_Actual): Split
28323 N_Formal_Subprogram_Declaration into two alternatives for the new
28324 cases N_Formal_Abstract_Subprogram_Declaration and
28325 N_Formal_Concrete_Subprogram_Declaration.
28326 Char_Literal_Value field is now a Uint.
28328 * trans.c: Get rid of junk Uint2 reference.
28329 Char_Literal_Value field is now a Uint.
28330 (gnat_to_gnu, case N_Aggregate): Check TYPE_UNCHECKED_UNION_P.
28331 (gigi): Correct third arg to gimplify_body.
28333 * ada-tree.h: (TYPE_UNCHECKED_UNION_P): New flag.

28345 * sinput.ads, sinput.adb (Skip_Line_Terminators): Extend to deal with
28346 wide character UTF_32 line terminators.
28347 Initialize Main_Source_File to avoid error when no main
28350 * errout.adb (Finalize): Do not check Num_SRef_Pragmas
28351 (Main_Source_File) when no main source has been loaded, to avoid

28385 GNAT.OS_Lib.Set_Close_On_Exec.
28387 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
28388 the parent side as close-on-exec so that they are not inherited by the
28391 * g-os_lib.ads, g-os_lib.adb (Set_Close_On_Exec): New subprogram to
28392 set or clear the FD_CLOEXEC flag on a file descriptor.
28394 2005-02-09 Eric Botcazou <ebotcazou@adacore.com>
28395 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28399 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28400 on the field if Pragma Component_Alignment (Storage_Unit).
28401 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28402 side-effects as if it were a constant; also make SAVE_EXPR to protect
28404 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
28406 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
28407 (components_to_record): Test it.

28420 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28422 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28423 component of an array of arrays in an assignment context, and the
28424 aggregate has component associations that require sliding on
28425 assignment, force reanalysis of the aggregate to generate a temporary
28426 before the assignment.
28427 (Must_Slide): Make global to the package, for use in Gen_Assign.
28429 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28431 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28432 unchecked union with no inferable discriminants, return a
28433 Raise_Program_Error node, rather than inserting it at the point the
28435 (Expand_Record_Equality, Component_Equality): Handle properly the case
28436 where some subcomponent is an unchecked union whose generated equality
28437 code raises program error.
28439 2005-02-09 Doug Rupp <rupp@adacore.com>
28441 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.

28445 Arnaud Charlet <charlet@adacore.com>
28447 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28448 address of the exception registration. The Win32 version of this
28449 routine calls __gnat_install_SEH_handler() to initialize the SEH
28450 (Structured Exception Handling) handler.
28451 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28452 SEH (Structured Exception Handling) now.
28453 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28454 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28455 preprocessor condition protecting the call to the extra eh setup
28456 subprogram, which is only available for the ppc target.
28457 (__gnat_clear_exception_count): replaced reference to
28458 variable taskIdCurrent by call to taskIdSelf(), cleaner.
28460 * seh_init.c: New file.
28462 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
28463 (GNATBIND_OBJS): Idem.
28465 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28466 routine takes a new parameter (a pointer to the exception registration
28467 for the SEH (Structured Exception Handling) support.
28469 * raise.h: (__gnat_install_SEH_handler): New prototype.
28470 Update copyright notice.
28472 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28473 record and initialize it by calling __gnat_install_SEH_handler.

28498 -shared-libgcc is now used by default on some systems (e.g. linux with
28500 Remove references to Makefile.prolog/generic, no longer used.
28502 2005-02-09 Vincent Celier <celier@adacore.com>
28504 * prj-makr.adb (Process_Directory): Put file name in canonical case
28505 before matching against the patterns.
28506 If gnatname has been invoked as <prefix>-gnatname
28507 then invoke the compiler as <prefix>-gcc, not just "gcc".
28509 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28511 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28512 with expansion disabled. The actual subtype is needed among other
28513 places when the selected component appears in the context of a loop
28514 bound, and denotes a packed array.
28515 (Operator_Check): Always use the first subtype in the
28516 error message, to avoid the appearance of internal base types.
28517 (Transform_Object_Operation): Copy each actual in full
28518 to the parameter associations of the constructed call, rather than
28519 using the shallow copy mechanism of New_Copy_List. This ensures that
28520 the chaining of named associations is done properly.
28521 (Complete_Object_Operation): Rewrite node, rather than
28522 replacing it, so that we can trace back to the original selected
28525 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28526 and calls that use object notation, if the called function is not
28527 declared in a withed unit, place the elaboration constraint on the
28528 unit in the context that makes the function accessible.
28529 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28530 imposes an elaboration constraint between two packages.
28532 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28534 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28535 views of a private type after handling its private dependents, to
28536 maintain proper stack discipline between entry and exit from the
28539 2005-02-09 Cyrille Comar <comar@adacore.com>

28552 recursion warnings when compiled with -gnatdm.
28554 2005-02-09 Robert Dewar <dewar@adacore.com>
28556 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28557 Slight fix to documentation of -gnaty with no parameters
28559 * xr_tabls.ads: Add ??? comment for missing overall comment
28561 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28562 we now use by default.
28564 * xsnames.adb: Adjust end of file test to look for five space followed
28565 by '#' instead of six spaces. The format of xsnames.adb was modified
28566 in the last update.
28568 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28571 * clean.adb: Minor reformatting.
28573 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28574 gnatname.adb: Minor reformatting
28575 Add 2005 to copyright output when utility is run
28577 * csets.adb: Eliminate obsolete comment
28579 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28582 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28584 2005-02-09 Sergey Rybin <rybin@adacore.com>
28586 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28587 the difference between compact and incompact layout and add the record
28588 representation clause to the example illustrating different layouts.
28589 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28590 component clauses").
28592 2005-02-09 Florian Villoing <villoing@adacore.com>
28594 * gnat_ugn.texi: Fix typos.
28595 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28597 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28598 in the generated documentation.
28600 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28602 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

28609 Document the procedure to debug the DllMain routine on Windows.
28610 Add note about -funwind-tables and mixed Ada and C/C++ programming in
28612 Document new BIND qualifer /RETURN_CODES=VMS.

28642 * exp_util.ads: Minor correction in comment.
28644 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28646 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28647 since this procedure is now too complex to be worth inlining.

29242 (Post_Parse_Context_Clause): Get Resolved_Path as a case-sensitive path.
29243 When comparing with project paths on the stack, first put the resolved
29244 path in canonical case.
29245 (Parse_Single_Project): Set the path name of the project file in the
29246 tree to the normalized path.
29248 * prj-proc.ads, prj-proc.adb (Check, Recursive_Check, Process): Remove
29249 parameter Process_Languages, no longer needed.

29258 (Current_Spec_Suffix => Ada_Spec_Suffix, Current_Body_Suffix =>
29261 * snames.ads, snames.adb: New standard names: Ada_Roots, Binder_Driver,
29262 Compiler_Driver, Compiler_Kind, Compute_Dependency, Default_Linker,
29263 Externally_Built, Include_Option, Language_Processing.
29265 * makegpr.adb: Numerous changes due to changes in packages
29268 * gnatls.adb: Add the default project dir (<prefix>/log/gnat) by
29269 default to the project path, except whe "-" is one of the directories

29277 * gnat1drv.adb (Gnat1drv): If debug flag A set, then automatically
29280 * repinfo.adb (List_Rep_Info): Remove special handling of -gnatdA
29281 flag. No longer needed now that we handle this in gnat1drv.adb.

29290 TYPE_SIZE_UNIT of result type if SIZE is not specified.
29291 (make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation
29292 of a bitfield, which we know is useless and causes trouble because of
29293 alignment implications.
29295 * utils.c (create_var_decl): Set DECL_COMMON again on targets without
29297 (process_attributes): Clear DECL_COMMON again when a section attribute
29299 (finish_record_type): Independently track if RECORD_TYPE has SIZE and/or
29300 SIZE_UNIT already set and use to compute final SIZE and SIZE_UNIT.
29301 (create_field_decl): Special case ADDRESSABLE negative to mean
29302 "no bitfield creation", to be used by make_aligning_type. Don't
29303 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
29304 fields claimed addressable still have to be bitfields. Use
29305 value_factor_p instead of a raw binop construction to check for the
29306 position's alignment.
29308 2004-12-07 Geert Bosch <bosch@adacore.com>

29313 Ed Schonberg <schonberg@adacore.com>
29315 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29316 with an implicit dereference as its prefix, use
29317 Insert_Explicit_Dereference instead of merely rewriting the prefix into
29318 an explicit dereference. This ensures that a reference to the original
29319 prefix is generated, if appropriate.
29321 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29322 dereference is rewritten to an explicit one, generate a reference to
29323 the entity denoted by its prefix using the original prefix node, so
29324 the dereference can be properly recorded as a read of the denoted
29325 access value, if appropriate.
29327 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29328 emitting 'assigned but never read' warning on a variable on the basis
29329 that it has an access type.
29330 (Check_References): Emit unreferenced warning when the scope is a

29339 * exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
29340 leaving call unchanged.
29341 This deals with the case where the pragma Import specified
29342 an external name, to be handled by the back end.
29344 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29345 subprogram which is Imported with convention Intrinsic if an
29346 External_Name argument is specified.
29347 (Process_Import_Or_Interface): Properly diagnose link name argument.
29348 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
29349 with Sem_Ch6.Cannot_Inline.

29363 Specific_Build_Stub_Target): New subprograms.
29364 (Build_Subprogram_Calling_Stubs): Make this procedure independent from
29365 the PCS implementation used, using the above PCS-customized subprograms.

29367 (PolyORB_Support.Helpers): New subunit containing supporting subprograms
29368 for generation of DSA code targeted to the PolyORB PCS.
29369 (Add_Stub_Type): Rewrite to isolate the parts that are specific to one
29370 implementation of the partition communication subsystem in ancillary
29372 (Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,
29373 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29374 PCS-specific part of Add_Stub_Type.
29375 (Insert_Partition_Check): Use runtime library function to perform
29378 * rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref

29398 2004-12-07 Ed Schonberg <schonberg@adacore.com>
29401 (Generate_Reference): Handle properly a reference to an entry formal,
29402 when an accept statement has a pragma Unreferenced for it.
29404 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29405 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29406 the body, to ensure that warnings are properly emitted for each accept
29407 statement of a given task entry.

29435 (Remove_Next): Same cleanup
29437 2004-12-07 Thomas Quinot <quinot@adacore.com>
29439 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29440 used to record an implicit dereference as a read operation on its
29441 prefix when operating under -gnatc. Necessary to avoid spurious
29442 'variable assigned but never read' warnings in that mode.
29443 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29444 is a non-overloaded implicit dereference, call the above subprogram to
29445 ensure proper recording of references.
29447 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29449 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
29450 to be resolved later as part of Analyze_Iteration_Scheme's call to

29497 2004-12-07 Vincent Celier <celier@adacore.com>
29499 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29500 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29501 and -eit to -ept. Added qualifier
29502 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29504 2004-11-27 Andreas Schwab <schwab@suse.de>
29506 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29508 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29510 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29511 internal implementation unit GNAT.Sockets.Thin,
29512 as their usage for sockets is non-portable (using the read and write
29513 functions from the system runtime library is fine on UNIX but won't
29514 work under Windows).
29516 * mingw32.h: Update copyright notice.
29518 2004-11-25 Arnaud Charlet <charlet@adacore.com>

29566 (void *)0 and (void *)1.
29567 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29569 * gigi.h (others_decl, all_others_decl): New decls representing the
29570 new Others_Value and All_Others_Value objects.
29571 (struct attrib): Rename "arg" component as "args", since GCC expects a
29572 list of arguments in there.
29574 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29575 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29578 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29579 others_decl and all_others_decl instead of hardcoded dummy addresses
29580 to represent "others" and "all others" choices, which is cleaner and
29581 more flexible with respect to the possible eh pointer encoding policies.
29583 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29584 (process_attributes): Account for the naming change of the "args"
29585 attribute list entry component.
29587 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29588 cumulating attributes for different entities into a single list.
29589 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29590 attributes for the current entity and propagate first subtype
29591 attributes to other subtypes.
29592 <E_Procedure>: Attribute arguments are attr->args and not
29593 attr->arg any more.
29594 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29595 argument provided, as this is what GCC expects. Use NULL_TREE instead

29633 (First_RCI_Subprogram_Id): Document this constant.
29634 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29636 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29637 replaced with calls to Get_Library_Unit_Name_String. Previously there
29638 were several instances of the same code in different locations in the
29639 compiler; this checkin completes the replacement of all of these
29640 instances with calls to a common subprogram.
29641 Minor reformatting.
29643 * sem_dist.adb: Remove comment noting that RPC receiver generation
29644 should be disabled for RACWs that implement RASs.

29670 (Expand_Pragma_Psect_Object): New procedure
29671 These procedures contain the revised and cleaned up processing for
29672 these two pragmas. This processing was formerly in Sem_Prag, but
29673 is more appropriately moved here. The cleanup involves making sure
29674 that the pragmas are properly attached to the tree, and that no
29675 nodes are improperly shared.
29677 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29678 pragmas to Exp_Prag, which is more appropriate.
29679 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29680 check for duplicates Remove use of Is_Psected flag, no longer needed.
29681 Use new Make_String_Literal function with string.
29683 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29684 that are functions return universal values, that have to be converted
29685 to the context type.
29686 Use new Make_String_Literal function with string.
29687 (Get_Stream_Convert_Pragma): New function, replaces the use of
29688 Get_Rep_Pragma, which had to be kludged to work in this case.
29690 * freeze.adb: Use new Has_Rep_Pragma function
29692 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29693 function with string.
29694 Use new Has_Rep_Pragma function.

29718 Robert Dewar <dewar@adacore.com>
29720 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29721 discriminant of a constrained subtype, analyze the copy of the
29722 corresponding constraint, because in some cases it may be only
29723 partially analyzed.
29724 Removes long-lived ??? comments.
29726 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29727 handled controlled or secondary-stack expressions within the
29728 iteration_scheme of a loop.
29730 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29731 bounds that may contain functions calls, to prevent memory leaks when
29732 the bound contains a call to a function that uses the secondary stack.
29733 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29734 generate temporaries for loop bounds that might contain function calls
29735 that require secondary stack and/or finalization actions.
29737 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29738 selected component and the selector is overloadable (not just a
29739 function) treat as function call, Analyze_Call will disambiguate if
29741 (Analyze_Selected_Component): Do not generate an actual subtype for the
29742 selected component if expansion is disabled. The actual subtype is only
29743 needed for constraint checks.

29745 not permit objects to be declared of a stream type, or of a
29746 composite type containing a stream.
29748 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29749 No_Streams no longer prohibits with'ing this package.
29751 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29752 discriminants, but the parent base has unknown discriminants, there is
29753 no discriminant constraint to inherit. Such a discrepancy can arise
29754 when the actual for a formal type with unknown discriminants is a
29755 similar private type whose full view has discriminants.
29756 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29757 do not permit objects to be declared of a stream type, or of a
29758 composite type containing a stream.
29760 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29762 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29763 protected operations.
29765 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29766 generated name, it complicates decoding in gdb and hinders debugging
29767 of protected operations.
29768 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29769 flag for the protected entry barrier function.
29770 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29771 flag for the protected entry function.
29773 2004-11-18 Nicolas Setton <setton@adacore.com>
29775 * expect.c: Define __unix__ when __APPLE__ is defined.
29777 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29778 Darwin-specific section.
29780 * lang-specs.h: Change the placement of the %1 marker.
29781 Works around the fact that gcc adds -fPIC by default under Darwin.
29783 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29785 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29786 type of the object with the packed array type, set the Analyzed flag
29787 on the object if it is an entity or simple indexed component, to avoid
29788 spurious type errors.
29790 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29792 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29793 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29794 separate line from the version message.
29796 2004-11-18 Ed Falis <falis@adacore.com>
29798 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29800 (init_float): Eliminate initialization of floating point status for
29801 AE653. The instructions have no effect for vThreads.
29803 2004-11-18 Vincent Celier <celier@adacore.com>
29805 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29806 gnatbind is invoked with -shared.
29808 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29810 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29811 for Detect_Blocking which is redundant with the check done within the
29812 procedure Protected_Single_Entry_Call.
29813 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29814 Detect_Blocking which is redundant with the check done within the
29815 procedure Protected_Single_Entry_Call.
29817 2004-11-18 Vincent Celier <celier@adacore.com>
29819 * makegpr.adb (Compile): Put the compiling switches (in package
29820 Compiler and on the command line) immediately after "-c", instead of
29821 at the end of the command line invocation of the compiler, when
29822 compiling a non-Ada file.
29823 (Build_Global_Archive): When there is no need to rebuild the archive,
29824 set Global_Archive_Exists, so that the archive is passed to the linker
29827 2004-11-18 Robert Dewar <dewar@adacore.com>
29828 Sergey Rybin <rybin@adacore.com>
29831 Remove extra paren check from list of checks for redundant constructs
29832 Add documentation of new -gnatyx style check (check extra parens)
29833 Remove paragraph about gnatelim debug options.
29835 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29836 objects rather than forbidding dependencies on the package Ada.Streams.
29838 * sinfo.ads: Add ??? note that we should document pragmas passed to
29841 * g-expect.ads: Fix a few typos in the comments.
29843 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29845 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29848 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29850 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29852 2004-11-07 Andreas Schwab <schwab@suse.de>
29854 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29856 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29859 * Makefile.in (darwin): Set soext to .dylib.
29861 2004-10-26 Vincent Celier <celier@gnat.com>
29862 Thomas Quinot <quinot@act-europe.fr>
29864 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29865 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29866 there is no use of GNAT.Sockets.Constants.
29867 Remove remaining pragma Import for C_Write
29868 Remove C_Read and C_Write from internal implementation unit
29869 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29870 the read and write functions from the system runtime library is fine
29871 on UNIX but won't work under Windows).
29873 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29874 (Check_Selector): Use C_Recv instead of C_Read.
29875 Selectors are the GNAT.Sockets abstraction to perform a select()
29876 call on a set of descriptors. To allow abortion of an ongoing
29877 select operation, some data is written to a dedicated socket that
29878 is always monitored.
29879 Under Windows, the write and read library functions cannot operate
29880 on sockets, so we need to use send and recv instead, which is portable
29881 across all supported platforms.
29883 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29884 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29885 (using the read and write functions from the system runtime library is
29886 fine on UNIX but won't work under Windows).
29888 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29890 * mlib-tgt-darwin.adb: New file.
29892 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29893 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29894 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29895 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29898 * Makefile.in: Add support for building shared libraries under Darwin.
29899 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29900 the low level EH init subprogram to be called from __gnat_initialize.
29902 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29903 indicates which options to pass to the archive indexer.
29905 * mlib-utl.adb: Add support for calling ranlib with additional
29906 options. This is needed for instance under Mac OS X.
29907 (Ranlib_Options): New global variable, used to store the potential
29908 options to pass to ranlib.
29909 (Ar): Use Ranlib_Options when spawning ranlib.
29910 (Initialize): Set the value of ranlib option.
29912 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29914 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29915 instead of 8K, to reflect the real potential needs for stack-checking
29918 2004-10-26 Pascal Obry <obry@gnat.com>
29920 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29922 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29923 Windows only the initial thread stack size can be set so it is good to
29924 start we a low stack size.
29925 The OS will adjust the size as needed.
29927 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29928 Nicolas Setton <setton@act-europe.fr>
29930 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29931 "__unix__" instead of "unix".
29932 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29933 sections were just mistakenly ignored. The former is
29934 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29935 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29936 of hpux. This prevents an unwanted definition of the symbol
29937 convert_addresses in adaint.o.
29939 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29941 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29942 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29944 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29946 * a-filico.ads, a-filico.adb: fix incorrect header.
29948 2004-10-26 Javier Miranda <miranda@gnat.com>
29950 * a-ststio.ads: Fix typo in identifier
29952 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29954 * sem_ch4.adb: Minor reformatting.
29956 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29958 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29959 enabled, check the result of unary and binary operations when the
29960 expression is the right-hand side of an assignment.
29962 2004-10-26 Vincent Celier <celier@gnat.com>
29964 * clean.adb (Delete): Do not output warnings when in quiet output and
29965 not in verbose mode.
29966 (Force_Deletions): New Boolean flag, defaulted to False
29967 (Delete): Only delete a file if it is writable, and when
29968 Force_Deletions is True.
29969 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29970 (Usage): Line for new switch -f
29971 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29974 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29976 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29977 JM type only if its size matches that of the wrapper. When a size is
29978 prescribed and the field is not aliased, remove the wrapper of a JM
29979 type only if the size is not greater than that of the packed array.
29980 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29983 2004-10-26 Geert Bosch <bosch@gnat.com>
29985 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29986 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29987 (Pred): Implement in terms of Succ.
29989 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29991 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29992 unchecked conversion is safe for in-place use if the expression of the
29993 conversion is safe.
29994 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29995 be expandable in place even if the aggregate does not come from source.
29996 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29997 designated object of an allocator in place, rather than building it
29998 first on the stack. The previous scheme forces a full copy of the array,
29999 and may be altogether unsusable if the size of the array is too large
30000 for stack allocation.
30002 2004-10-26 Robert Dewar <dewar@gnat.com>
30004 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30005 compares if the component is atomic.
30007 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30008 array assignment if the component type is atomic.
30010 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30011 Eric Botcazou <ebotcazou@act-europe.fr>
30013 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30014 is aliased and is a by_reference type, do not pass by copy.
30015 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30016 detect whether the call is in the right side of an assignment or
30017 the expression of an object declaration. Recurse on component
30018 association within aggregates.
30019 Call it in the condition that determines whether the temporary is
30020 necessary for correct stack-checking.
30022 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30024 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30025 RACW_Type, used in the PolyORB version.
30026 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30027 version and the GARLIC version.
30029 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30030 Rename RCI_Info to RCI_Locator for better consistency between the
30031 GARLIC and PolyORB versions of the distributed systems annex.
30032 (DSA_Implementation_Name): This enumeration lists the possible
30033 implementations of the Partition Communication Subsystem for the
30034 Distributed Systems Annex (DSA). The three available implementations
30035 are the dummy stub implementation (No_DSA), and two versions based on
30036 two different distribution runtime libraries: GARLIC and PolyORB. Both
30037 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30039 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30042 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30043 between the GARLIC and PolyORB versions of the distributed systems
30045 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30047 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30049 * gnat1drv.adb: Suppress calling the back end when
30050 Frontend_Layout_On_Target is true.
30052 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30054 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30055 Set_Read_Only): New subprograms.
30056 These new routines allow the user to set or unset the Owner execute
30057 and Owner write permission flags on a file.
30059 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30060 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30062 2004-10-26 Matthew Gingell <gingell@gnat.com>
30064 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30066 2004-10-26 Pascal Obry <obry@gnat.com>
30068 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30069 memory before the faulting page we properly test the process read
30070 access for this address using appropriate Win32 routine.
30071 (HPUX sections): guard with "__hpux__" instead of "hpux".
30073 2004-10-26 Robert Dewar <dewar@gnat.com>
30075 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30076 entry parameter if pragma Unreferenced set, since we do not properly
30077 handle the case of multiple parameters.
30079 2004-10-26 Vincent Celier <celier@gnat.com>
30081 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30082 (Ada_Objects_Path.Add): For a library project, add to the object path
30083 the library directory only if there is no object directory or if the
30084 library directory contains ALI files.
30085 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30087 2004-10-26 Vincent Celier <celier@gnat.com>
30089 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30090 extension of library projects.
30092 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30093 path defaults to ".:<prefix>/lib/gnat".
30094 (Parse): For an extending all project, allow direct import of a project
30095 that is virtually extended.
30097 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30098 the specified name is directly imported, return its ID. Otherwise, if
30099 an extension of this project is imported, return the ID of the
30102 2004-10-26 Robert Dewar <dewar@gnat.com>
30104 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30105 (Sub3): New procedure, used by Scaled_Divide
30106 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30107 correct more than one instance of failure to propagate carries
30109 (Double_Divide): Handle overflow case of largest negative number
30110 divided by minus one.
30112 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30113 the case of a quotient value out of range.
30116 2004-10-26 Robert Dewar <dewar@gnat.com>
30118 * s-bitops.adb (Bit_Eq): Remove redundant check.
30120 * s-bitops.ads: Minor comment updates
30121 Change some occurrences of Address to System.Address
30123 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30125 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30127 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30128 accessibility check to prefix that is a protected operation.
30130 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30132 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30133 empty, post message on stub.
30135 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30136 Javier Miranda <miranda@gnat.com>
30138 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30139 current instance appears within a unit that is directly in the context
30141 Used to determine whether the body of the instance should be analyzed
30142 immediately after its spec, to make its subprogram bodies available
30143 for front-end inlining.
30144 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30145 constraint is not allowed on the component type (AARM 12.5.3(3))
30147 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30149 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30150 'Storage_Pool): enhance, document & limit detection of non-sharable
30153 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30155 * s-pooglo.ads: Add more documentation now that this pool is properly
30158 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30160 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30161 or protected type with discriminants, do not constrain the
30162 corresponding record type if the subtype declaration has no
30163 discriminant constraints. This can be the case in source code, or in
30164 the subtype declaration created to rename an actual type within an
30167 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30169 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30170 different kind of stub (possibly wrong name for file), do not check
30172 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30173 includes call to some function that returns an unconstrained type, do
30176 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30178 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30179 appear in the code for the main unit. Dependencies among units in the
30180 context of the main unit are established when those other units are
30181 compiled. Otherwise spurious elaboration constraints can generate
30182 incorrect elaboration circularities.
30184 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30185 Ed Schonberg <schonberg@gnat.com>
30187 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30188 subprogram is called with a parameter that is not an object name. This
30189 situation arises for some cases of illegal code, which is diagnosed
30190 later, and in this case it is wrong to call Is_Aliased, as that might
30191 cause a compiler crash.
30192 (Explain_Limited_Type): Refine previous fix to include
30193 inherited components of derived types, to provide complete information.
30195 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30196 is the prival for a protected object.
30197 It is necessary to mark this entity as a variable, in addition to
30198 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30199 modified to avoid checking the Aliased flag on entities that are not
30200 objects. (Checking that flag for non-objects is erroneous and could
30201 lead to a compiler crash).
30203 2004-10-26 Robert Dewar <dewar@gnat.com>
30205 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30206 X_Frac = 0.5, then we know that the number X must be positive.
30207 (Succ): Remove the same redundant test, and also fix the primary test
30208 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30210 (Decompose): Add fuller comments to spec
30212 2004-10-26 Pascal Obry <obry@gnat.com>
30214 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30215 validity (process must have read access). Set to 0 in all other cases.
30216 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30217 violation on Win32.
30218 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30219 segmentation violation.
30221 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30223 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30224 whose type is a constructed subtype of an aliased object with an
30225 unconstrained nominal subtype, convert the actual to the constructed
30226 subtype before taking its address.
30228 2004-10-26 Vincent Celier <celier@gnat.com>
30230 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30231 (Is_Path_Name_Case_Sensitive): New function
30233 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30234 (Base_Name, Simple_Name, Current_Directory, Compose,
30235 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30238 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30239 Vasiliy Fofanov <fofanov@act-europe.fr>
30240 Vincent Celier <celier@gnat.com>
30242 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30243 "memory management issues" section and document some of the useful
30244 memory pools provided as part of the GNAT library.
30245 Remove "virtual" from declaration of A::method2 in
30246 the simple example of Ada/C++ mixed system.
30247 Library Projects may be virtually extended: their virtual extensions
30248 are not Library Projects.
30249 Added section on extending project hierarchies.
30251 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30253 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30255 (__gnat_portable_spawn): Remove const.

30270 * Makefile.in: Define and use RANLIB_FLAGS.
30272 2004-10-04 Pascal Obry <obry@gnat.com>
30274 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30275 other x86 platforms).
30277 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30279 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30280 in general and triggers stack alignment adjustment for thread entry
30281 points on targets where this is necessary.
30283 2004-10-04 Bernard Banner <banner@gnat.com>
30286 * Makefile.in: Add section for powerpc linux
30287 Add variant i-vxwork-x86.ads
30289 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30291 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30293 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30294 table registration calls when need be. Ensures no reference to the crt
30295 ctors symbol are issued in the SJLJ case, which avoids possible
30296 undefined symbol errors in the case of modules to be statically linked
30299 2004-10-04 Javier Miranda <miranda@gnat.com>
30301 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30302 in-line the code corresponding to subprogram Analyze_Actuals. In
30303 addition, analyze the actuals only in case of subprogram call.
30305 2004-10-04 Ed Falis <falis@gnat.com>
30307 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size

30318 (Analyze_Block_Statement): Add circuitry to detect following dead code
30319 (Check_Unreachable_Code): Handle case of block exit
30321 2004-10-04 Robert Dewar <dewar@gnat.com>
30323 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30324 (XMatchD): Avoid warning for Logic_Error call
30326 2004-10-04 Robert Dewar <dewar@gnat.com>
30328 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30329 consider expressions buried within a procedure actual to be an actual.
30330 This caused some blowups with uses of packed slices within a procedure
30333 2004-10-04 Robert Dewar <dewar@gnat.com>
30335 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30336 longer need to be initialized to zero.
30337 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30338 initialized to zero.
30340 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30341 considered valid, even if the representation is modular. That's correct
30342 now that we no longer initialize packed modular arrays to zero.
30344 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30345 suffixes. These are now documented as the only cases in which the
30346 debugger ignores outer records.
30347 Previously, the spec allowed arbitrary suffixes for this purpose.
30348 Change name of LJM to JM for packed array pad records
30349 Create separate section on packed array handling, and add a whole new
30350 set of comments to this section describing the situation with packed
30351 modular types and justification requirements depending on endianness.
30353 2004-10-04 Robert Dewar <dewar@gnat.com>
30355 * a-except.adb: Add a comment for last change
30357 * einfo.ads: Minor spelling correction in comment
30359 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting

30369 Inline_Always when in Configurable_Run_Time mode.
30371 * sem_prag.adb (Process_Convention): If entity is an inherited
30372 subprogram, apply convention to parent subprogram if in same scope.
30373 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30374 when in Configurable_Run_Time mode.
30376 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30378 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30379 class_wide type after component list has been inherited.

30383 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30384 Denotes_Previous_Actual, to handle properly the case of a private
30385 actual that is also the component type of a subsequent array actual.
30386 The visibility status of the first actual is not affected when the
30387 second is installed.
30388 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30389 make fully recursive the treatment of formals of packages declared
30391 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30392 the above on exit from an instantiation.
30393 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30394 current instantiation which is now complete.
30395 (Analyze_Package_Instantiation): No instantiated body is needed if the
30396 main unit is generic. Efficient, and avoid anomalies when a instance
30397 appears in a package accessed through rtsfind.
30399 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30401 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30402 do not generate a declaration for a temporary if the call is part of a
30403 library-level instantiation.
30405 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30407 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30408 searching for a limited component to flag.
30410 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30411 expansion of Input, to account for the fact that the implicit call
30412 generated by the attribute reference must freeze the user-defined
30413 stream subprogram. This is only relevant to 'Input, because it can
30414 appear in an object declaration, prior to the body of the subprogram.
30416 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30417 expansion can proceed and further errors uncovered.
30418 (Minor clean up): Fix cases of using | instead of \ for continuation
30421 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30423 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30425 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30426 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30427 Use gcc_assert and gcc_unreachable.
30429 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30430 specified alignment before validating size.
30431 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30432 stripped-down declaration for the type of the inner field when making
30435 * utils.c (finish_record_type): Do not compute the size in units
30436 incrementally. Instead compute it once for the rep clause case.
30437 Use gcc_assert and gcc_unreachable.
30439 2004-10-04 Vincent Celier <celier@gnat.com>
30441 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30443 (Is_Valid_Path_Name): Take '/' as a directory separator.
30445 2004-10-04 Vincent Celier <celier@gnat.com>
30447 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30448 (Extended_Project) only if Extended_Project is defined, to avoid
30450 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30452 (Parse_Single_Project): Ditto.
30454 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30455 Add_To_Project_Path for virtual projects.
30457 2004-10-04 Vincent Celier <celier@gnat.com>
30459 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

30463 parameter Options_2.
30465 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30466 Build_Dynamic_Library with an empty Options_2.
30468 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30471 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30472 directory separator, if any.
30473 (Gprmake): Do not allow mains on the command line for library projects.
30474 Do not attempt to link when the project is a library project.
30475 (Library_Opts): New table to store Library_Options.
30476 (Build_Library): If Library_Options is specified, pass these options
30477 when building a shared library.
30479 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30481 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30482 the end of this procedure now that the unlock operation was inserted
30485 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30487 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30488 corresponding to the Preallocated_Stacks flags in System.
30489 (Get_Target_Parameters): Including the processing for
30490 Preallocated_Stacks.

30498 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
30499 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
30500 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
30501 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30502 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30503 used to signal whether the compiler creates the required stacks and
30504 descriptors for the different tasks (when True) or it is done by the
30505 underlying operating system at run time (when False).
30506 It is initially set to False in all targets.
30508 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30509 if it is supported by the target.
30510 (Make_Task_Create_Call): Pass the stack address if it has been
30511 previously created. Otherwise pass a Null_Address.
30513 * snames.adb: Add _stack.
30515 * snames.ads: Add Name_uStack. Required to allow the expander to
30516 statically allocated task stacks.
30518 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30519 Stack_Address argument.
30520 Check that its value is equal to Null_Address because this target does
30521 not support the static stack allocation.
30523 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30525 * usage.adb: Change "pragma inline" to "pragma Inline" in information

30530 * exp_dist.adb: Split declaration of asynchronous flag out of
30531 Add_RACW_Read_Attribute.
30532 Minor reformatting for better alignment with PolyORB version.
30533 Store the entity for the asynchronous flag of an RACW, rather than the
30534 expression, in the asynchronous flags table. This will allow this flag
30535 to be used in other subprograms beside Add_RACW_Read_Attribute.
30537 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30539 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
30540 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,

30543 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30544 sockets constant MSG_NOSIGNAL (Linux-specific).
30545 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30546 all Send operations.
30547 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30548 from trigerring SIGPIPE.
30549 Rename components to avoid clash with Ada 2005 possible reserved
30551 (Check_Selector): When the select system call returns with an error
30552 condition, propagate Socket_Error to the caller.
30554 2004-10-01 Jan Hubicka <jh@suse.cz>
30556 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

30564 Change "pragma inline" to "pragma Inline" in information and error
30566 Minor reformatting.
30568 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30569 right way of doing things after all.
30570 (Freeze_Entity): For object, set Is_Public for imported entities
30571 unless there is an address clause present.
30573 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30575 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30576 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30577 ensures proper handling of types with rep clauses, which might have
30578 their TYPE_SIZE set already.
30580 2004-09-21 Robert Dewar <dewar@gnat.com>
30582 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30583 packed array types in both little- and big-endian cases. This change
30584 ensures that we no longer count on the unused bits being initialized
30585 for such types (and in particular ensures that equality testing will
30586 only read the relevant bits).
30587 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30588 These changes mean that we no longer need to initialize small packed
30590 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30591 optimization to an LJM field as to its parent field.
30593 * ada-tree.h, trans.c, utils.c, utils2.c:
30594 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30596 2004-09-20 Jan Hubicka <jh@suse.cz>
30598 * utils.c (gnat_finalize): Remove.
30599 (end_subprog_body): Directly call cgraph_finalize_function;
30600 do not lower the nested functions.
30602 2004-09-20 Robert Dewar <dewar@gnat.com>
30605 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30606 if an address clause is present, since that means that the Import
30609 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30611 * 5tsystem.ads: Removed, no longer used.
30613 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>

30616 * ada-tree.def: Use tree_code_class enumeration constants
30617 instead of code letters.
30618 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
30619 Update for new tree-class enumeration constants.

30635 an existing directory.
30636 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30637 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30638 Convert the result to File_Size.
30640 * prj.ads: (Project_Error): New exception
30642 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30643 Prj.Com, not from Osint.
30644 (Attrs, Package_Attributes): Tables moved to private part of spec
30645 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30647 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30648 Prj.Project_Error after call to Fail.
30649 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30650 Fail. Check that package name is not already in use.
30652 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30653 used by tools, not only by the project manager, and to indicate that
30654 exception Prj.Prj_Error may be raised in case of problem.
30655 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30657 (Attrs, Package_Attributes): Table instantiations moved from the body to
30658 the private part to be accessible from Prj.Attr.PM body.

30661 from new package Prj.Attr.PM.
30662 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30665 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
30667 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
30668 instead of Elaboration_Checks).
30670 * a-calend.adb: Minor reformatting
30672 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

30713 pragmas recognized by GNAT.
30715 * gnat_rm.texi: Document pragma Detect_Blocking.
30717 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,

30750 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
30751 Program_Error if called from a protected operation, and increase the
30752 protected action nesting level.

30754 protected action nesting level.
30756 * s-tposen.adb (Lock_Entry): When pragma Detect_Blocking is active,
30757 raise Program_Error if called from a protected operation, and increase
30758 the protected action nesting level.
30759 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
30760 Program_Error if called from a protected operation, and increase the
30761 protected action nesting level.
30762 (Protected_Single_Entry_Call): When pragma Detect_Blocking is active,
30763 raise Program_Error if called from a protected operation.
30764 (Timed_Protected_Single_Entry_Call): When pragma Detect_Blocking is
30765 active, raise Program_Error if called from a protected operation.
30766 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
30767 protected action nesting level.
30769 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30770 insertion of the statement raising Program_Error. The run time
30771 contains the required machinery for handling that.
30773 * sem_util.ads: Change comment associated to procedure
30774 Check_Potentially_Blocking_Operation.
30775 This procedure does not insert a call for raising the exception because
30776 that is currently done by the run time.
30778 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30780 * init.c: Add the global variable __gl_detect_blocking that indicates
30781 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30782 making the pragma available at run time.
30783 (__gnat_set_globals): Pass and update the detect_blocking parameter.

30786 pragma Detect_Blocking is active.
30788 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30790 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30791 DB is found in the ali file. Any unit compiled with pragma
30792 Detect_Blocking active forces its effect in the whole partition.
30794 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30795 Detect_Blocking is active and delay is called from a protected
30798 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30799 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30800 Detect_Blocking is active (0 otherwise).
30801 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30802 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
30805 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
30807 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30808 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30811 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30812 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30813 Update API in placeholder implemetation of s-parint to reflect changes
30814 in distribution runtime library.
30816 * sem_ch3.adb (Expand_Derived_Record): Rename to
30817 Expand_Record_Extension.
30819 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30820 primitive operations of potentially distributed object types that have
30821 non-controlling anonymous access formals.
30823 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30825 New implementation of expansion for remote access-to-subprogram types,
30826 based on the RACW infrastructure.
30827 This version of sem_dist is compatible with PolyORB/DSA as well as
30830 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30831 Asynchrronous that applies to a remote access-to-subprogram type, mark
30832 the underlying RACW type as asynchronous.
30834 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30835 __gnat_using_gnu_linker to 1.
30837 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30838 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

30844 * exp_ch3.adb (Expand_Derived_Record): Rename to
30845 Expand_Record_Extension.
30846 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30847 a component declaration must remain attached at that point in the
30848 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30849 It is therefore necessary to take a copy of the expression when building
30850 the corresponding assignment statement in the init proc.
30851 As a side effect, in the case of a derived record type, we now see the
30852 original expression, without any rewriting that could have occurred
30853 during expansion of the ancestor type's init proc, and we do not need
30854 to go back to Original_Node.
30856 * exp_ch3.ads (Expand_Derived_Record): Rename to
30857 Expand_Record_Extension.
30859 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

30862 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
30863 New subprograms. Used to create a proxy tagged object for a remote
30864 subprogram. The proxy object is used as the designated object
30865 for RAS values on the same partition (unless All_Calls_Remote applies).
30866 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30867 System.Partition_Interface.Get_Unique_Remote_Pointer.
30868 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30869 Renamed from Add_RAS_*_Attribute.
30870 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
30872 New implementation of expansion for remote access-to-subprogram types,
30873 based on the RACW infrastructure.
30875 * exp_dist.ads (Copy_Specification): Update comment to note that this
30876 function can copy the specification from either a subprogram
30877 specification or an access-to-subprogram type definition.
30879 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30881 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30882 in an instance, between an explicit subprogram an one inherited from a
30883 type derived from an actual.
30885 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30886 add a polling call if the subprogram is to be inlined by the back-end,
30887 to avoid repeated calls with multiple inlinings.
30889 * checks.adb (Apply_Alignment_Check): If the expression in the address
30890 clause is a call whose name is not a static entity (e.g. a dispatching
30891 call), treat as dynamic.
30893 2004-09-09 Robert Dewar <dewar@gnat.com>
30895 * g-trasym.ads: Minor reformatting
30897 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

30908 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30909 enable map file generation. Add the right option to generate the map
30910 file if Map_File is set to True.
30912 * gnatdll.adb (Gen_Map_File): New variable.
30913 (Syntax): Add info about new -m (Map_File) option.

30931 2004-09-09 Cyrille Comar <comar@act-europe.fr>
30933 * opt.adb (Set_Opt_Config_Switches): Use Ada_Version_Runtime to compile
30936 * opt.ads: Add Ada_Version_Runtime constant used to decide which
30937 version of the language is used to compile the run time.
30939 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
30941 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
30942 of variable length temporaries for function return now that the
30943 back-end and gigi support it.

30994 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
30995 packed indexed component where array is an IN OUT formal. This
30996 generated garbage code previously.
30998 * gnat_ugn.texi: Document -fverbose-asm
31000 * gnat-style.texi: Minor updates (note that boolean constants and
31001 variables are joined with AND/OR rather than short circuit forms).

31005 * exp_util.adb (Safe_Unchecked_Type_Conversion): Conversion is safe if
31006 it is an upward conversion of an untagged type with no representation

31014 * checks.adb (Apply_Access_Checks): Do not generate checks when
31015 expander is not active (but check for unset reference to prefix of
31018 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
31019 pragma Debug as an if statement with a constant condition, for
31020 consistent treatment of entity references contained within the
31021 enclosed procedure call.
31023 2004-09-01 Vincent Celier <celier@gnat.com>
31025 * bindgen.adb: (Set_EA_Last): New procedure
31026 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure
31028 (Gen_Adafinal_Ada): If no finalization, adafinal does nothing

31050 2004-09-01 Pascal Obry <obry@gnat.com>
31052 * gprcmd.adb (Extend): Do not output trailing directory separator. This
31053 is not needed and it confuses Windows GNU/make which does not report
31054 directory terminated by a slash as a directory.
31055 (gprcmd): Idem for "pwd" internal command.
31057 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
31058 target names rewrite to fix regressions with recent version of

31110 2004-08-16 Pascal Obry <obry@gnat.com>
31112 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
31113 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
31114 option and not mdll anymore. Update comment.
31116 2004-08-16 Pascal Obry <obry@gnat.com>
31118 * bld.adb (Put_Include_Project): Properly handle directory separators
31121 2004-08-16 Ed Schonberg <schonberg@gnat.com>

31134 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
31136 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
31137 for a global aliased object with a variable size and an unconstrained
31138 nominal subtype, pretend there is no initializer if the one we have is
31139 incomplete, and avoid referencing an inexistant component in there. The
31140 part we have will be rebuilt anyway and the reference may confuse
31141 further operations.
31143 2004-08-13 Thomas Quinot <quinot@act-europe.fr>
31145 * einfo.ads: Minor reformatting
31147 * lib-writ.adb (Output_Main_Program_Line): Do not set parameter

31161 2004-08-13 Ed Schonberg <schonberg@gnat.com>
31163 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
31164 unit, this is an attempt to inline a construct that is not available in
31165 the current restricted mode, so abort rather than trying to continue.
31167 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
31168 discriminants that rename those of the parent, recover names of
31169 original discriminants for the constraint on the full view of the
31171 (Complete_Private_Subtype): Do not create a subtype declaration if the
31172 subtype is an itype.
31174 * gnat_rm.texi: Added section on implementation of discriminated
31175 records with default values for discriminants.
31177 2004-08-13 Ed Schonberg <schonberg@gnat.com>
31180 * sem_res.adb (Make_Call_Into_Operator): Handle properly the case where
31181 the second operand is overloaded.

31196 Change calls to GNAT.Sockets.Thin.Is_Socket_In_Set to account for
31197 new specification and test explicitly for non-zero return value.
31199 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
31200 returning C.int, to avoid using a derived boolean type.
31202 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
31203 Duplicate_Subexpr_No_Checks in preference to direct use of
31204 Remove_Side_Effects and New_Copy_Tree.

31228 2004-08-09 Olivier Hainque <hainque@act-europe.fr>
31230 * decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Adjust condition to
31231 ignore overflows on low and high bounds of an index to also account for
31232 differences in signedness between sizetype and gnu_index_subtype.
31233 These are as legitimate as the ones caused by a lower TYPE_PRECISION
31236 2004-08-09 Robert Dewar <dewar@gnat.com>
31238 * s-solita.ads, s-solita.adb: Minor reformatting
31240 * gnat_rm.texi: Add documentation for pragma Profile (Restricted)
31241 Move pragma Restricted_Run_Time, No_Run_Time, Ravenscar to new
31242 obsolescent section
31243 Add note that No_Implicit_Conditionals does not suppress

31762 * sem_util.adb (Normalize_Actuals): If there are no actuals on a
31763 function call that is itself an actual in an enclosing call, diagnose
31764 problem here rather than assuming that resolution will catch it.
31766 * sem_ch7.adb (Analyze_Package_Specification): If the specification is
31767 the local copy of a generic unit for a formal package, and the generic
31768 is a child unit, install private part of ancestors before compiling
31769 private part of spec.

31777 Remove_Parents): Handle properly a parent unit that is an
31778 instantiation, when the unit has been rewritten as a body for inlining

31796 generated name for string variable, to avoid spurious conflicts with
31797 the name of the type of a single protected object.
31799 * exp_ch4.adb (Expand_Array_Equality): If indices are distinct, use a
31800 loop with an explicit exit statement, to avoid generating an
31801 out-of-range value with 'Succ leading to spurious constraint_errors

31804 2004-07-15 Thomas Quinot <quinot@act-europe.fr>
31806 * sem_ch4.adb (Analyze_Slice): Always call Analyze on the prefix: it
31807 might not be analyzed yet, even if its Etype is already set (case of an
31808 unchecked conversion built using Unchecked_Convert_To, for example).
31809 If the prefix has already been analyzed, this will be a nop anyway.
31811 * exp_ch5.adb (Make_Tag_Ctrl_Assignment): For an assignment of a
31812 controller type, or an assignment of a record type with controlled
31813 components, copy only user data, and leave the finalization chain

31900 for a renaming, stabilize the initialization expression if we are at a

33155 interpretations for rewritten right operand.
33156 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

33792 Merge from tree-ssa-20020619-branch.
33794 * config-lang.in (boot_language, build_by_default): Set

33860 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33861 overriding, use the operation of the parent unconditionally.
33863 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33864 operation when either operand is a literal, to avoid further
33867 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
33868 overridden by a previous explicit declaration, mark the previous entity

33938 limitation on length of lines when scanning config pragma files.

35130 * sem_ch3.adb (Inherit_Components): If derived type is private and has
35131 stored discriminants, use its discriminants to constrain parent type,
35132 as is done for non-private derived record types.
35134 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
35135 Ada 2005 AI-310: an abstract non-dispatching operation is not a
35136 candidate interpretation in an overloaded call.
35138 * tbuild.adb (Unchecked_Convert_To): Preserve conversion node if
35139 expression is Null and target type is not an access type (e.g. a
35140 non-private address type).
35142 2004-04-05 Thomas Quinot <quinot@act-europe.fr>
35144 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
35145 statement whose right-hand side is an inlined call, save a copy of the
35146 original assignment subtree to preserve enough consistency for
35147 Analyze_Assignment to proceed.
35149 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
35150 complete assignment subtree which is now unnecessary, as the expansion
35151 of inlined call has been improved to preserve a consistent assignment
35152 tree. Note_Possible_Modification must be called only
35153 after checks have been applied, or else unnecessary checks will
35156 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35157 of explicit dereferences that do not Come_From_Source:
35158 - be selective on cases where we must go back to the dereferenced
35159 pointer (an assignment to an implicit dereference must not be
35160 recorded as modifying the pointer);
35161 - do not rely on Original_Node being present (Analyze_Assignment
35162 calls Note_Possible_Modification on a copied tree).
35164 * sem_warn.adb (Check_References): When an unset reference to a pointer
35165 that is never assigned is encountered, prefer '<pointer> may be null'
35166 warning over '<pointer> is never assigned a value'.

35176 libexc. We currently don't reference anything in this library and
35177 linking it in triggers linker warnings we don't want to see.
35179 * init.c: Update comments.

35227 * exp_aggr.adb (Get_Component_Val): Treat a string literal as
35228 non-static when building aggregate for bit-packed array.
35230 * exp_ch4.adb (Expand_N_Slice): If a packed slice is an actual of a
35231 function call that is itself the actual in a procedure call, build
35234 * exp_pakd.adb (Expand_Bit_Packed_Element_Set): If right-hand side is
35235 a string literal, create a temporary for it, constant folding only
35236 handles scalars here.
35238 2004-04-01 Vincent Celier <celier@gnat.com>

35412 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
35414 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35415 executable name when not initialized. Otherwise, use its current value.
35417 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35418 initialize it to another executable name than the current one. This
35419 allows to configure paths for an executable name (gnatmake) different
35420 from the current one (gnatdist).
35422 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35424 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35425 current unit cannot be inlined if it appears in the body of a withed
35426 unit, to avoid order of elaboration problems in gigi.
35428 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35429 information for protected (wrapper) operation as well, to simplify gdb
35432 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35433 protected body, indicate that the entity for the generated spec comes
35434 from source, to ensure that references are properly generated for it.

35442 that renames an equality operator and the operands are overloaded,
35443 resolve them with the declared formal types, before rewriting as an

35469 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35471 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35472 attribute reference does not denote a subtype, it can be any
35473 expression that has a classwide type, potentially after an implicit
35474 dereference. In particular, the prefix can be a view conversion for
35475 a classwide type (for which Is_Object_Reference holds), but it can
35476 also be a value conversion for an access-to-classwide type. In the
35477 latter case, there is an implicit dereference, and the original node
35478 for the prefix does not verify Is_Object_Reference.
35480 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35481 conversion of a discriminant-dependent component of a mutable object
35484 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35486 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35487 inherited, has convention C, and has unconstrained array parameters,
35488 place the corresponding warning on the derived type declaration rather
35489 than the original subprogram.

35492 indication on renaming declaration, if formal has a box and actual

35496 determine whether to generate an implicit or explicit reference to
35497 the renamed entity.

35500 subprogram renaming comes from a defaulted formal subprogram in an
35503 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35505 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35506 value expressions to ensure that calls within a component definition
35507 will be checked (since those are evaluated during the record type's

35558 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35559 declaration for a child subprogram body that acts as a spec, indicate
35560 that the entity in the declaration needs debugging information.
35562 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35563 full view if the subtype is created for a constrained record component;
35564 gigi has enough information to construct the record, and there is no
35565 place in the tree for the declaration.
35567 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35568 serial number for the dummy body that is built for analysis, to avoid
35569 inconsistencies in the generation of internal names when compiling

35605 * ada-tree.h: Update copyright notice.
35606 Minor reformatting.
35608 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35610 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35611 as regular exception objects and not as mere integers representing the
35612 condition code. The latter approach required some dynamics to mask off
35613 severity bits, which did not fit well into the GCC table based model.
35614 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35615 exception data objects. We don't it and it would conflict with the other
35616 external symbol we have to generate for such exceptions.
35618 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35619 the special code for VMS exceptions, since these are now represented
35620 as regular exceptions objects.

35662 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35663 When needed (stack checking) the stack size is retrieved
35664 from the VxWorks kernel.
35666 * Makefile.in: Flag -nostdinc is required when building the run time
35667 for avoiding looking for files in the base compiler.

35700 dirs, when a directory already present is added, the duplicate is
35701 removed and the directory is always put as the last in the table.
35702 Write the path files at the end of these accumulations.

35754 imaginary parts, use Double precision throughout.
35756 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35757 we want to be able to compile run-time with -gnata for testing, but
35758 this may also be instantiated in user code that is compiled with -gnata.

35791 New accessors to allow easy access to GNAT exception data
35793 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the

35795 routine which will now be able to call the appropriate exception data
35798 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35799 component of Standard_Exception_Type to be the closest possible to
35800 Exception_Code in System.Standard_Library, that we cannot get at this
35801 point. Expand a ??? comment to notify that this type node should
35802 probably be rewritten later on.

35805 registration call to include a pointer to the exception object in the
35808 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In

35822 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35824 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35826 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35827 taken care of in Scan_Make_Arg.
35828 (Scan_Make_Arg): Add the executable suffix only if the argument
35829 following -o, in canonical case, does not end with the executable
35830 suffix. When in verbose mode and executable file name does not end
35831 with executable suffix, output the executable name, in canonical case.

35853 corresponding dispatch entry is properly initialized.
35854 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35855 when looking for user-defined equality operation.

35911 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
35912 Insert_Dereference_Action when rewriting an implicit dereference into
35913 an explicit one, this will be taken care of during expansion of the
35914 explicit dereference.
35915 (Expand_N_Slice): Same. Always do the rewriting, even for the case
35916 of non-packed slices, since the dereference action generated by
35917 expansion of the explicit dereference is needed in any case.

35919 analyze and resolve the rewritten explicit dereference so it is seen
35921 (Insert_Dereference_Action): This procedure is now called only for the
35922 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
35923 dereferences that do not come from source (including explicit

37245 lib-xref.adb, sem_ch5.adb, sem_ch7.adb, sem_ch8.adb:
37246 Minor reformatting and code clean ups.
37247 Minor changes to prevent -gnatwa warnings
37249 * ali.adb: Minor reformatting and cleanup of code
37250 Acquire new SS indication of secondary stack use from ali files
37252 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
37253 (since now we expect this to be done for imported functions)
37255 * bindgen.adb: Generate call to modify default secondary stack size if
37258 * bindusg.adb: Add line for new -D switch
37260 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
37261 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
37262 Add circuitry for both records and arrays to avoid gigi
37263 processing if the type involved has non-bit-aligned components
37265 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37266 N_String_Literal node always references an E_String_Literal_Subtype
37267 entity. This may not be true in the future.
37268 (Possible_Bit_Aligned_Component): Move processing of
37269 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37271 * exp_ch6.adb (Expand_Thread_Body): Pick up
37272 Default_Secondary_Stack_Size as variable so that we get value modified
37273 by possible -Dnnn binder parameter.
37275 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37276 (Type_May_Have_Bit_Aligned_Components): New function.
37278 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.
37279 (Type_May_Have_Bit_Aligned_Components): New function.

37286 importing constant atomic/volatile objects.
37287 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
37288 unless explicit Pure_Function pragma given, to avoid insidious bug of
37289 call to non-pure imported function getting eliminated.
37291 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb,
37292 gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,
37293 gnatxref.adb, gprcmd.adb, gprep.adb, make.adb: Minor reformatting

37307 New switch Sec_Stack_Used (GNAT, GNATBIND)
37308 Make Default_Secondary_Stack_Size a variable instead of a constant,
37309 so that it can be modified by the new -Dnnn bind switch.
37311 * rtsfind.adb (Load_Fail): Give full error message in configurable
37312 run-time mode if all_errors mode is set. This was not done in the case
37313 of a file not found, which was an oversight.
37314 Note if secondary stack unit is used by compiler.
37316 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37317 ineffective elaborate all pragmas on non-visible packages (this
37318 happened when a renamed subprogram was called). Now the elaborate all
37319 always goes on the package containing the renaming rather than the one
37320 containing the renamed subprogram.
37322 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37323 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37326 has an Etype that references an E_String_Literal.
37327 (Eval_String_Literal): Avoid assumption that N_String_Literal node
37328 always references an E_String_Literal_Subtype entity. This may not
37329 be true in the future.
37331 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
37334 * sem_res.adb (Resolve): Specialize msg for function name used in proc
37337 2004-01-05 Ed Falis <falis@gnat.com>

37344 * bld.adb: Minor comment updates
37345 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
37348 * make.adb (Gnatmake): Special process for files to compile/check when
37349 -B is specified. Fail when there are only foreign mains in attribute
37350 Main of the project file and -B is not specified. Do not skip bind/link
37351 steps when -B is specified.
37353 * makeusg.adb: Document new switch -B

37376 -gnatwa warning on static condition.
37378 2004-01-05 Doug Rupp <rupp@gnat.com>

37382 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37384 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37385 all attributes, including read-only attribute.
37387 2004-01-05 Pascal Obry <obry@gnat.com>

37390 library naming scheme.
37392 * mlib-prj.adb (Build_Library): Generate different names for the static
37393 or dynamic version of the GNAT runtime. This is needed to support the
37394 new shared library naming scheme.

37396 based on the new naming scheme.
37398 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
37399 scheme for the shared runtime libraries.
37402 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
37404 (install-gnatlib): Do not create symlinks for shared libraries.
37405 (gnatlib-shared-default): Idem.
37406 (gnatlib-shared-dual-win32): New target. Not used for now as the
37407 auto-import feature does not support arrays/records.
37408 (gnatlib-shared-win32): Do not create copy for the shared libraries.
37409 (gnatlib-shared-vms): Fix shared runtime libraries names.
37411 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
37412 dependent runtime shared library name.
37414 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
37416 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
37419 2004-01-05 Ed Schonberg <schonberg@gnat.com>
37421 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37422 protected objects when allocator has a subtype indication, not a
37423 qualified expression. Note that qualified expressions may have to be
37424 checked when limited aggregates are implemented.
37426 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
37427 pure, emit warning.
37428 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
37429 subprogram is imported, remove warning.
37431 2004-01-05 Geert Bosch <bosch@gnat.com>

37473 * cstand.adb (Create_Standard): Change the way how the declaration of
37474 the Duration type is created (making it the same way as it is for all
37475 the other standard types).
37477 2003-12-17 Robert Dewar <dewar@gnat.com>

37485 the expression type only if it is declared in the current unit.
37487 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
37488 are universal and already analyzed, as can occur in constrained
37489 subcomponents that depend on discriminants, when one constraint is a
37492 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
37493 type Any_Fixed is legal as the argument of a conversion, if only one
37494 fixed-point type is in context.

37505 2003-12-15 Vincent Celier <celier@gnat.com>
37507 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
37508 (Gnatchop): Do not set failure status when reporting the number of
37511 2003-12-15 Doug Rupp <rupp@gnat.com>
37513 * s-ctrl.ads: New file.

37535 2003-12-11 Ed Falis <falis@gnat.com>
37537 * 5zinit.adb: Clean up.
37539 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37540 to __gnat_map_signal, imported from init.c to support
37541 signal -> exception mappings that depend on the vxWorks version.
37544 Created and exported __gnat_map_signal to support signal -> exception
37545 mapping that is dependent on the VxWorks version.
37546 Change mapping of SIGBUS from Program_Error to Storage_Error on VxWorks
37548 2003-12-11 Vasiliy Fofanv <fofanov@act-europe.fr>

37574 Minor reformatting throughout
37576 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37578 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37579 bounds of a loop, create a separate block in order to generate proper
37580 cleanup actions to prevent memory leaks.
37582 * sem_res.adb (Resolve_Call): After a call to
37583 Establish_Transient_Scope, the call may be rewritten and relocated, in
37584 which case no further processing is needed.
37586 * sem_util.adb: (Wrong_Type): Refine previous fix.
37587 Fixes ACATS regressions.
37590 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always

37596 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
37599 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37602 2003-12-08 Robert Dewar <dewar@gnat.com>
37604 * 7sintman.adb: Minor reformatting
37606 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37607 standard linker options to get standard libraries linked. We now plan
37608 to provide dummy versions of these libraries to match the appropriate
37609 configurable run-time (e.g. if a library is not needed at all, provide
37610 a dummy empty library).
37612 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37613 options (-L parameters and standard libraries). What we plan to do is
37614 to provide dummy libraries where the libraries are not required.
37616 * gnatbind.adb: Minor comment improvement
37618 2003-12-08 Javier Miranda <miranda@gnat.com>
37620 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37621 aggregate in the parent. Otherwise constants with limited aggregates
37622 are not supported. Add new formal to pass the component type (Ctype).
37623 It is required to call the corresponding IP subprogram in case of
37624 default initialized components.
37625 (Gen_Assign): In case of default-initialized component, generate a
37626 call to the IP subprogram associated with the component.
37627 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37628 of aggregate with default initialized components.
37629 (Has_Default_Init_Comps): Improve implementation to recursively check
37630 all the present expressions.
37632 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37633 to indicate that the initialization call corresponds to a
37634 default-initialized component of an aggregate.
37635 In case of default initialized aggregate with tasks this parameter is
37636 used to generate a null string (this is just a workaround that must be
37637 improved later). In case of discriminants, this parameter is used to
37638 generate a selected component node that gives access to the discriminant
37641 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37642 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37643 allocated aggregates with default-initialized components.
37645 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37646 the box notation is used in positional aggregates.

37664 Set the scanner to return ends of line and comments as tokens, if
37665 Store_Comments is True.
37666 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
37667 comments are associated with these nodes. Store the node IDs in the
37669 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
37671 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
37672 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
37673 current project. Call Tree.Restore afterwards. Set the various nodes
37674 for comment storage (Next_End, End_Of_Line, Previous_Line,
37677 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
37678 defaulted to False.
37680 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
37681 to False. When Truncated is True, truncate the string, never go to the
37683 (Write_End_Of_Line_Comment): New procedure
37684 (Print): Process comments for nodes N_With_Clause,
37685 N_Package_Declaration, N_String_Type_Declaration,
37686 N_Attribute_Declaration, N_Typed_Variable_Declaration,
37687 N_Variable_Declaration, N_Case_Construction, N_Case_Item.
37688 Process nodes N_Comment.
37690 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37691 without comments and there are some comments, set the flag
37692 Unkept_Comments to True.
37693 (Scan): If there are comments, set the flag Unkept_Comments to True and
37694 clear the comments.
37695 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
37696 (Next_End_Nodes: New table
37697 (Comment_Zones_Of): New function
37698 (Scan): New procedure; moved from Prj. Accumulate comments in the

37713 (Set_First_Comment_Before, Set_First_Comment_Before_End): New procedures
37714 (Set_Next_Comment): New procedure
37715 (Default_Project_Node): Associate comment before if the node can store

37721 * scng.ads, scng.adb (Comment_Is_Token): New Boolean global variable,
37722 defaulted to False.
37723 (Scan): Store position of start of comment. If comments are tokens, set
37724 Comment_Id and set Token to Tok_Comment when scanning a comment.
37725 (Set_Comment_As_Token): New procedure
37727 * sinput-p.adb: Update Copyright notice
37728 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
37729 that no longer exists.
37731 2003-12-08 Javier Miranda <miranda@gnat.com>
37733 * sem_aggr.adb: Add dependence on Exp_Tss package
37734 Correct typo in comment
37735 (Resolve_Aggregate): In case of array aggregates set the estimated
37736 type of the aggregate before calling resolve. This is needed to know
37737 the name of the corresponding IP in case of limited array aggregates.
37738 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37739 in case of default initialized array components.
37741 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited
37742 types. Required to give support to limited aggregates in generic
37745 2003-12-08 Ed Schonberg <schonberg@gnat.com>
37747 * sem_ch3.adb (Check_Initialization): For legality purposes, an
37748 inlined body functions like an instantiation.
37749 (Decimal_Fixed_Point_Declaration): Do not set kind of first subtype
37750 until bounds are analyzed, to diagnose premature use of type.
37752 * sem_util.adb (Wrong_Type): Improve error message when the type of
37753 the expression is used prematurely.
37755 2003-12-08 GNAT Script <nobody@gnat.com>
37757 * Make-lang.in: Makefile automatically updated
37759 2003-12-08 Arnaud Charlet <charlet@act-europe.fr>

41469 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41470 function approach did not work well because of a side effect (the
41471 function call could reallocate the table which was being indexed
41472 using its result). Fixes ada/4851.

41839 2001-12-17 Laurent Pautet <pautet@gnat.com>
41842 Fix comment of Shutdown_Socket and Close_Socket. These functions
41843 should not fail silently because if they are called twice, this
41844 probably means that there is a race condition in the user program.
41845 Anyway, this behaviour is consistent with the rest of this unit.
41846 When an error occurs, an exception is raised with the error message
41847 as exception message.

41996 (Copy_Generic_Node): Deal with incorrect reference to Associated_Node

41999 (Associated_Node): Documentation explicitly mentions attribute
42000 reference nodes, since this field is used in such nodes.

43166 * exp_ch7.adb (Make_Transient_Block): if statement is within
43167 exception handler, always use new transient scope to place Clean
43170 2001-10-11 Pascal Obry <obry@gnat.com>
43173 (GNAT_ADA_OBJS): add g-crc32.o, a-tags.o, a-stream.o
43174 (GNATBIND_OBJS): add g-crc32.o, a-tags.o, a-stream.o
43175 (GNATLS_RTL_OBJS): add g-crc32.o
43176 (GNATMAKE_RTL_OBJS): add g-crc32.o
43179 (CRC_Match): new function.
43180 (Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
43181 instead of the previous simple checksum algorithm.
43182 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43183 (Set_Source_Table): idem.
43186 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43187 instead of simple checksum.
43188 (CRC_Match): new function.
43189 (CRC_Error): new constant.
43191 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43192 a CRC now and not a simple checksum. A CRC uses lower-case hex
43193 letters, fixes ambiguity in parsing.
43195 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43196 is what this variable will store.
43198 * bcheck.adb: Change reference to chechsum in comments by CRC.
43199 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43200 rename All_Checksum_Match to All_CRC_Match. Change due to API
43201 renaming since now GNAT does not use a simple checksum but a
43202 CRC using GNAT.CRC32.
43204 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43205 now and not anymore a simple checksum.
43207 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
43210 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
43213 (Restore_Scan_State): rename Checksum to CRC.
43214 (Save_Scan_State): idem.
43218 (Checksum): rename to CRC.
43219 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
43221 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
43222 GNAT.CRC32). Update copyright notice.
43224 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
43225 GNAT.CRC32). Update copyright notice.
43228 (Accumulate_Checksum): removed.
43229 (Update): new procedure. Add a wide-character into the CRC.
43232 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
43233 (Load_File): fix initialization of S (change Source_Checksum to
43236 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
43237 Source_CRC in S initialization.
43239 * sinput.adb (Source_Checksum): renamed to Source_CRC.
43241 * sinput.ads (Source_Checksum): renamed to Source_CRC.
43242 Update comments for the CRC.
43244 * types.adb (Hex): Use lowercase for the letter part.
43246 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43247 for a word. This is currently used only for CRC. In previous version,
43248 the checksum was using a representation with all letter being
43249 upper-case. With the new implementation (using CRC) we do not remove
43250 the 32th bit of the CRC, so we can have an upper-case starting letter
43251 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43252 It is ambigous since the CRC was optional and could be followed by
43253 options like EB, EE. So now this routines uses lower-case letter for
43254 the hexadecimal representation. Strange enough only lower case letters
43255 where checked in Scan_ALI (even if this was not a possible case).
43257 * gnatvsn.ads (Library_Version): changed to 3.15a.
43259 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43262 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
43265 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
43266 Add 2001 to copyright notice
43267 (Accumulate_Checksum): Modify to use System.CRC32.
43269 * ali-util.ads: Redo changes of previous revision to continue to use
43270 the word Checksum. Add 2001 to copyright notice.
43272 * ali.adb: Undo some of previous changes, not needed.
43273 Keep the change for lower case letters in the checksum.
43275 * ali.ads: Undo previous change not needed.
43277 * bcheck.adb: Undo most of previous change, not needed.
43278 But do use Checksums_Match for checksum comparison.
43280 * gnatls.adb: Undo most of previous change, not needed.

43305 * sinput.adb: Undo previous change, not needed.
43307 * sinput-l.adb: Undo previous change, not needed.
43309 * sinput.ads: Undo previous change, not needed. Keep only comment
43310 on new checksum algorithm
