905 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
906 Orig_Prev to Prev in the case where the actual is N_Function_Call or
907 N_Identifier. This was interfering with other cases that are rewritten

2953 * exp_disp.adb (Make_DT, Make_Secondary_DT, Make_Tags): Avoid
2954 generating dispatch tables of locally defined tagged types statically.
2955 Remove implicit if-statement that is no longer required.
2956 (Expand_Dispatching_Call): If this is a call to an instance of the
2957 generic dispatching constructor, the type of the first argument may be
2958 a subtype of Tag, so always use the base type to recognize this case.
2960 2008-05-20 Thomas Quinot <quinot@adacore.com>
2963 (GARLIC_Support.Add_RACW_Read_Attribute): When a zero value is received,
2964 and the RACW is null-excluding, raise CONSTRAINT_ERROR instead of

2974 2008-05-20 Kevin Pouget <pouget@adacore.com>
2976 * exp_smem.ads, exp_smem.adb: Construction of access and assign
2977 routines has been replaced by an instantiation of
2978 System.Shared_Storage.Shared_Var_Procs generic package, while expanding
2979 shared variable declaration.
2980 Calls to access and assign routines have been replaced by calls to
2981 Read/Write routines of System.Shared_Storage.Shared_Var_Procs
2982 instantiated package.
2984 * rtsfind.ads: RE_Shared_Var_Procs entry has been added in RE_Unit_Table
2985 It identifies the new generic package added in s-shasto.
2987 * s-shasto.adb, s-shasto.ads: A new generic package has been added, it
2988 is instantiated for each shared passive variable. It provides
2989 supporting procedures called upon each read or write access by the
2993 For this runtime unit (always compiled in GNAT mode), we allow
2994 stream attributes references for limited types for the case where
2995 shared passive objects are implemented using stream attributes,
2996 which is the default in GNAT's persistent storage implementation.
2998 2008-05-20 Ed Schonberg <schonberg@adacore.com>
3001 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
3002 convention from its base type, do not set the type to that of integer,
3003 because it may inherit a size clause.
3004 Warn on a size clause with a size different
3005 from that of Integer, if the type has convention C.
3007 2008-05-20 Vincent Celier <celier@adacore.com>

3045 (P_Access_Definition): Change the error message when parsing "access
3046 all" in Ada 95 mode. The message no longer forces the user to recompile
3047 in 05 mode only to discover that anonymous access types are not allowed
3050 2008-05-20 Hristian Kirtchev <kirtchev@adacore.com>
3053 (P_Protected): Update the error message on missing "-gnat05" switch when

3066 (Set_Categorization_From_Scope): Do not set In_Remote_Types unless in
3067 the visible part of the spec of a remote types unit.
3068 (Validate_Remote_Access_Object_Type_Declaration):
3069 New local subprogram Is_Valid_Remote_Object_Type, replaces
3070 Is_Recursively_Limited_Private.
3071 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
3072 non-controlling formals (and the return type, even though this is not
3073 explicit in the standard) must support external streaming.
3074 (Validate_RCI_Subprogram_Declaration): Enforce E.2.3(14) rules: same
3075 as above for of RAS types and RCI subprograms. (The return type is not
3077 Update comments related to RACWs designating limited interfaces per
3078 ARG ruling on AI05-060.
3080 * sem_util.ads, sem_util.adb
3081 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
3082 Is_Remote_Call_Interface to identify RACW types in a stable and
3083 consistent way. We used to rely in this predicate on the privateness of
3084 the designated type and its ancestors, but depending on the currently
3085 visible private parts, this caused false negatives. We now uniformly
3086 rely on checks made at the point where the RACW type is declared.

3095 restricting use of predefined assignment with tagged types that have

3098 constants declared in scopes other than packages since they can be
3099 completed with pragma Import.
3100 Add missing escaping of all-caps word 'CPP' in error messages.
3101 (Build_Discriminated_Subtype): Do not inherit representation clauses
3102 from parent type if subtype already carries them, because they are
3103 inherited earlier during derivation and already include those that may
3104 come from a partial view.
3106 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
3107 Check the declarations of a subprogram body for proper deferred
3108 constant completion.
3110 * sem_ch7.ads, sem_ch7.adb

3125 access-to-class-wide type.

3141 (Add_One_Interp): Ignore any interpretation that is a primitive
3142 operation of an RACW stub type (these primitives are only executed
3143 through dispatching, never through static calls).
3144 (Collect_Interps): When only one interpretation has been found, set N's
3145 Entity and Etype to that interpretation, otherwise Entity and Etype may
3146 still refer to an interpretation that was ignored by Add_One_Interp,
3147 in which case would end up with being marked as not overloaded but with
3148 an Entity attribute not pointing to its (unique) correct interpretation.
3150 2008-05-20 Ed Schonberg <schonberg@adacore.com>
3153 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

3163 (Print_Itype): Do not modify the sloc of the component type of a
3164 (packed) array itype, because it is an unrelated type whose source
3165 location is independent of the point of creation of the itype itself.

3204 2008-05-20 Arnaud Charlet <charlet@adacore.com>

3207 equivalent representation, but has the advantage of allowing
3208 compilation of this file under 64 bits platforms.

7273 clauses for inherited components of a type extension.
7274 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for

7407 subprogram body that acts as its own spec may not have a non-private
7408 WITH clause on a private sibling.
7409 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
7410 child unit is a renaming, create an implicit with_clause on that
7411 parent, and not on the unit it renames, to prevent visibility errors

7478 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
7479 type from a limited_with_clause, and the full view is available, use it
7480 for subsequent semantic checks.

7482 (Find_Primitive_Operation): New function.
7483 (Analyze_Overloaded_Selected_Component): insert explicit dereference

7510 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
7511 requeue statement is dispatching. Do not emit an error when the name is

7513 perform subtype conformance between the formals of the current entry
7514 and those of the target interface primitive.
7515 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
7516 Timed_Entry_Call): Analyze the triggering statement as the first step of
7517 the processing. If this is a dispatching select, postpone the analysis
7518 of all select statements until the Expander transforms the select. This

7520 replicated some of the select statements. In case the Expander is
7521 disabled, perform regular analysis.
7522 (Check_Triggering_Statement): New routine.
7523 (Analyze_Requeue): Exclude any interpretations that are not entries when
7524 checking overloaded names in a requeue. Also test type conformance for

8120 multiple inherited interfaces info. This information cannot be stored
8121 in Xref_Entity_Record, which only supports a single instance of Tref_*,

8138 additional management on these nodes in Expand_Interface_Actuals.
8140 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
8141 that handles use of 'Access and 'Unchecked_Access applied to
8142 actuals covering interface types. Such code is now
8143 centralized in Expand_N_Attribute_Reference.

8187 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
8188 used by VxWorks targets to have access to task-specific data and be
8189 able to extract the stack boundaries for stack checking.

8233 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
8234 association for an access component, add an association with null as
8235 the expression. Remove testing for array subtypes and the setting in
8236 that case of Ctyp to the array component type, which prevented proper
8237 inclusion of an association for null-initialized arrays. Collapse
8238 condition that tests for array subtypes into just a test of
8239 Is_Partially_Initialized_Type (which already covers arrays anyway).

8256 * sem_ch4.adb: Minor code and comment reformatting.
8257 (Analyze_Allocator): When the designated type of an unconstrained

8387 files instead of units to gigi.
8388 * gigi.h (struct File_Info_Type): New.
8389 (gigi): Rename and change type of number_units parameter, change
8390 type of file_info_ptr parameter.
8391 * trans.c (number_files): New global variable.
8392 (gigi): Rename and change type of number_units parameter, change
8393 type of file_info_ptr parameter.
8394 If mapped location support is enabled, create the isomorphic mapping
8395 between source files and line maps.
8396 (Sloc_to_locus): If mapped location support is enabled, translate
8397 source location into mapped location.
8398 (annotate_with_node): Rename into set_expr_location_from_node.

8424 * a-calend-vms.adb, a-calend.adb:
8425 Add a section on leap seconds control along with two entities used to
8426 enable and disable leap seconds support. The array Leap_Second_Times is
8427 now constant and contains hard time values pre-generated. Remove
8428 all elaboration code used to populate the table of leap seconds.
8431 Add entity Leap_Seconds_Support to the list of global run-time variables
8432 along with a comment on its usage and values.
8433 (Gen_Adainit_Ada): Add code to generate the declaration and import of
8434 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
8435 or one (enabled) depending on the presence of binder switch "-y".
8436 (Gen_Adainit_C): Add code to generate the declaration of external int
8437 __gl_leap_seconds_support. Set is value to zero (disabled) or one

8447 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
8448 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
8450 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
8452 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
8453 function which can be called by the debugger to interrupt the tasks of
8454 an Ada application asynchronously, as needed on VxWorks.
8455 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
8457 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,

8474 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
8476 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
8479 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
8481 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,

8488 2007-09-26 Javier Miranda <miranda@adacore.com>
8489 Eric Botcazou <ebotcazou@adacore.com>
8492 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
8493 indirection added to the HT_Link component of the TSD. This is required
8494 to statically allocate the TSD.
8497 Minor reordering of the declarations in the private part. Required to
8498 add a level of indirection to the contents of the TSD component HT_Link.
8499 This is required to statically allocate the TSD.
8501 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
8502 Is_Statically_Allocated set from constant objects.
8503 Do not make exported constants created by the compiler volatile.
8504 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
8507 * trans.c (Identifier_to_gnu): For constants, unshare initializers
8508 before returning them.
8510 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
8511 public part of the package.
8512 (Make_DT): Move HT_Link component out of the TSD record. For this
8513 purpose Make_DT now declares a separate object that stores the
8514 HT_Link value, and initializes the TSD component with the address
8515 of this new object. The addition of this level of indirection is
8516 required to statically allocate the TSD because the TSD cannot
8517 have variable components.
8518 (Expand_Interface_Conversion): Improve the expanded code.
8519 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
8521 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
8522 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
8523 if we are building static dispatch tables then we must not generate
8524 extra code to register the primitive because the dispatch table will
8525 be built at the end of the library package; otherwise we notify that
8526 we cannot build the static dispatch table.
8528 2007-09-26 Robert Dewar <dewar@adacore.com>
8530 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
8533 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
8534 (Analyze_Record_Representation_Clause): Suppress junk warning for
8535 missing component clause.

8545 for thunks associated with interface types.
8547 * einfo.ads: Improve documentatation of Is_Internal
8548 (Is_Thunk): New attribute applicable to subprograms. True for thunks
8549 associated with interface types.
8550 Extensive comment fixes regarding flags that appear in all entities. The
8551 documentation is now consistent for all such flags (there were a number
8552 of errors in the documentation in this regard).
8554 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
8556 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
8557 of these procedures are passed a function call that already has
8558 build-in-place actuals (testing new flag
8559 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
8560 the case where processing continues.
8561 (Expand_Call): If the call is generated from a thunk body then we
8562 propagate the extra actuals associated with the accessibility
8563 level of the access type actuals.
8565 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
8566 of each extra formal of a protected operation to reference the
8567 corresponding extra formal of the subprogram denoted by the
8568 operation's Protected_Body_Subprogram.
8570 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
8571 N_Function_Call nodes.
8573 2007-09-26 Robert Dewar <dewar@adacore.com>
8575 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
8577 * debug.adb: Add d.s flag.
8579 2007-09-26 Gary Dismukes <dismukes@adacore.com>
8581 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
8582 debug variable so that it won't be initialized when pragma
8583 Initialize_Scalars is in effect.
8585 2007-09-26 Gary Dismukes <dismukes@adacore.com>
8587 * freeze.adb (Freeze_Entity): Remove check for preelaborable
8588 initialization of a full view. This is moved to
8589 Analyze_Package_Specification.
8591 * sem_ch7.adb (Analyze_Package_Specification): Add check for
8592 preelaborable initialization of a full view in entity loop.
8593 (Uninstall_Declarations): If entity is a use-visible compilation unit,
8594 its child units are use-visible only if they are visible child units.
8596 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
8597 whether an expression can be used within a type declaration that
8598 requires preelaborable init.
8599 (Check_Components): Replace inline code that does partial checking for
8600 preelaborable default expressions with call to
8601 Is_Preelaborable_Expression.
8602 (Has_Preelaborable_Initialization): In the case of a generic actual
8603 subtype, (that is, Is_Generic_Actual is True), return the result of
8604 applying Has_Preelaborable_Initialization to the generic actual's base
8607 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
8609 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
8610 call to Jan_1_Day _Of_Week to optimize its performance.
8611 (Is_Leap): Move the routine to the scope of Week_In_Year.
8612 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
8613 weekday on which January 1 falls of Year - 1 and Year + 1. This function
8614 avoids calling Time_Of and Split, thus making it more efficent.
8615 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
8617 * g-calend.ads (Week_In_Year): Change comment to reflect new
8620 2007-09-26 Emmanuel Briot <briot@adacore.com>
8622 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
8623 Command_Line): New types
8624 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
8625 support for defining how switches can be grouped on a command line (as
8626 is the case for -gnatw... for GNAT), and how simple switches can be
8627 used as aliases for more complex switches (-gnatwa is same as
8629 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
8630 (Start, Current_*): New subprograms
8631 Added support for parsing an array of strings in addition to the real
8633 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
8634 be moved from the body to the private part of the spec.
8635 (*): All subprograms now have an extra parameter with default value to
8636 specify which parser should be used. For backward compatibility, it
8637 defaults to parsing the command line of the application. They were also
8638 modified to properly handle cases where each of the argument does not
8639 start at index 1 (which is always true for Ada.Command_Line, but not
8640 when processing any Argument_List).
8641 (Free): New subprogram
8642 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
8643 Argument): New subprograms
8644 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
8645 special characters like ':', '=',... are now handled in a single place,
8646 which makes the code more extensible eventually.
8647 (Getopt, Full_Switch): When the switch was returned as part of the
8648 special character '*', make sure it is prepended by the switch character
8649 ('-' in general), so that the application knows whether "foo" or "-foo"
8650 was specified on the command line.
8652 2007-09-26 Florian Villoing <villoing@adacore.com>
8654 * g-dirope.adb (Remove_Dir): In case we are removing directories
8655 recursively, make sure that if an exception is raised during the
8656 processing, the current working directory is reset to its initial
8657 value before propagating the exception.
8659 2007-09-26 Vincent Celier <celier@adacore.com>
8661 * gnatbind.adb: If there are several ALI files specified and there is
8662 a main program to bind, the first ALI is expected to contain the main
8663 subprogram and the names of the binder generated files will be derived
8664 from the first ALI file name.
8665 (Gnatbind): Fix insertion character in invocation of Error_Msg
8667 2007-09-26 Vincent Celier <celier@adacore.com>
8669 * gnatcmd.adb (Check_Files): Do not include sources that have been
8670 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
8672 2007-09-26 Ed Schonberg <schonberg@adacore.com>
8674 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
8675 information about each of its index types, following the type
8676 reference for its component type.
8678 2007-09-26 Vincent Celier <celier@adacore.com>
8680 * make.adb: (Kill): New procedure (__gnat_kill imported)

8687 sources, so that the correct paths will be found.
8689 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
8691 2007-09-26 Vincent Celier <celier@adacore.com>
8693 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
8695 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
8696 Replace components Compiler_Min_Options and Binder_Min_Options with
8697 Compiler_Required_Switches and Binder_Required_Switches in record
8699 Remove components Default_Language and Config in Project_Tree_Data,
8702 * prj-attr.adb: New attributes Required_Switches (<language>) in
8703 packages Compiler and Binder.
8705 * prj-nmsc.adb: Major rewrite of the processing of configuration
8706 attributes for gprbuild. No impact on GNAT tools.
8708 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
8709 process configuration attributes: this is done in Prj.Nmsc.Check.

8711 being extended, instead of a shallow copy.
8712 (Process_Project_Tree_Phase_1): New procedure

8714 (Process): Implementation now uses the two new procedures
8716 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
8717 from the project config, not the tree config that no longer exists.
8719 2007-09-26 Vincent Celier <celier@adacore.com>

8743 ancestor of the derived type, the operations are inherited from the
8744 primary dispatch table of the parent.
8745 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
8746 when the context is an explicit type conversion.

9045 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
9046 create an abstract subprogram in the case of 'Input. For 'Output we now
9047 create a real spec/body when the type is abstract, since it can
9048 potentially be called.
9049 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9050 body for 'Output when the type is abstract (only the creation of the
9051 body for 'Input is excluded when the type is abstract).
9052 (Stream_Operation_OK): Add an additional condition in the return
9053 statement, so that False will be returned for TTS_Stream_Input if the
9054 associated tagged type is an abstract extension. Add comments for
9056 (Expand_N_Object_Declaration): For the case of a shared passive
9057 variable, insert init proc call only after the shared variable
9058 procedures have been processed, because the IP call needs to undergo
9059 shared passive variable reference expansion, which requires these
9060 procedures to be available (and elaborated).

9071 and the value of the discriminant is the discriminant of the enclosing
9072 type, retrieve its value from the aggregate itself, where it must have
9075 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
9076 to remove other spurious ambiguities on arithmetic operations involving
9077 literals and addresses, on systems where Address is a visible integer
9078 type, when the operator is called in functional notation.
9079 (Try_Primitive_Operation): Within an instance, a call in prefixed form
9080 is legal when the types match, even if the operation is currently
9083 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9085 * sem_ch12.adb (Build_Local_Package): A formal package with no
9086 associations is legal if all formals have defaults. It is not
9087 equivalent to a formal declared with a box.

9206 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
9207 spurious ambiguities when integer literals appear in the context of an
9208 address type that is a visible integer type.
9210 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
9211 exceptions never being raised.
9212 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

9226 2007-08-31 Gary Dismukes <dismukes@adacore.com>
9228 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
9229 library-level package renaming, pass the declaration associated with
9230 the renaming's special debug variable to Qualify_Entity_Names to ensure
9231 that its encoded name is properly qualified.
9233 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
9234 occurring in the list of entities to qualify, and do not attempt to

9244 access type points to an unconstrained array.
9246 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
9248 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
9251 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect

9262 avoid very deep recursion in the front end, which was causing stack
9265 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
9266 string, and the right operand is a string literal (the case of "" &
9267 "..."), optimize by avoiding copying the right operand -- just use the
9268 value of the right operand directly.
9270 * stringt.adb (Store_String_Chars): Optimize by growing the
9271 String_Chars table all at once, rather than appending characters one by
9273 (Write_String_Table_Entry): If the string to be printed is very long,
9274 just print the first few characters, followed by the length. Otherwise,
9275 doing "pn(n)" in the debugger can take an extremely long time.
9277 * sem_prag.adb (Process_Interface_Name): Replace loop doing

9292 clauses of subunits, ignore limited_with_clauses that are illegal and
9293 have not been fully analyzed.
9295 2007-08-31 Ed Schonberg <schonberg@adacore.com>
9297 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
9298 flag, for effiency. It is called when analyzing arithmetic operators
9299 and also for actuals in calls that are universal_integers. The flag is
9300 set for the predefined type address, and for any type or subtype
9303 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
9304 Universal_Integer, when the formal is a descendent of address and the
9305 call appears in user code.
9306 (Analyze_Selected_Component): if the prefix is a private extension, the
9307 tag component is visible.
9309 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an
9312 2007-08-31 Robert Dewar <dewar@adacore.com>
9314 * s-fileio.adb (Open): Normalize file name to lower case in non-case
9315 sensitive file name systems to avoid unexpected mismatch in Vista.

9366 2007-08-16 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
9368 * misc.c (gnat_type_max_size): Constify.
9370 2007-08-16 Gary Dismukes <dismukes@adacore.com>
9372 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
9373 associated with Standard_Debug_Renaming_Type, to be used as the type of
9374 the special variables whose names provide debugger encodings for
9375 renaming declarations.
9377 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
9378 (Set_Debug_Renaming_Link): Change to set Node25.
9379 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
9380 (Write_Field25_Name): Add case for E_Variable to output
9381 "Debug_Renaming_Link".
9382 (Write_Field23_Name): Correct the output string for "Limited_View".
9384 * exp_dbug.adb: Add with and use of Tbuild.
9385 (Debug_Renaming_Declaration): Replace creation of an enumeration type
9386 and literal with creation of a variable of type
9387 Standard_Debug_Renaming_Type whose name encodes both the renamed object
9388 and the entity of the renaming declaration.
9389 (Qualify_Entity_Name): Add the delayed qualification of the entity name
9390 part of the name of a variable that has a Debug_Renaming_Link.
9392 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
9393 special type to be associated with variables that provide debugger
9394 encodings for renaming declarations.

9397 Ed Schonberg <schonberg@adacore.com>
9398 Javier Miranda <miranda@adacore.com>
9400 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
9401 ancestor part given by an aggregate to test for an unchecked conversion,
9402 since this can occur in some cases when the ancestor part is a function
9403 call, and we don't want to fall into the recursive call to this
9404 procedure in that case.
9406 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
9407 stream attributes on limited types to account for user-specified
9408 attributes as well as whether Input (resp. Output) becomes available
9409 due to Read (resp. Write) being available for the type. Change Boolean
9410 variable to the more accurate name
9411 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
9412 double-"not" predicate at beginning of return statement to more
9413 understandable form.
9415 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
9416 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
9417 in a block statement and use that as the first statement of the
9418 expanded return rather than incorrectly using the handled sequence as
9419 the first statement.
9421 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
9422 operation, generate an explicit freeze node for it rather than
9423 generating extra formals, to ensure that gigi has the proper order of
9424 elaboration for anonymous subtypes in the signature of the subprograms.
9425 (Build_In_Place_Formal): Move assertion to beginning of loop.
9426 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
9427 applied to a function call (occurs for some cases of 'Input).
9428 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
9429 applied to a function call (occurs for some cases of 'Input).
9431 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
9432 2005, generate an extended return statement enclosing the result object
9435 * freeze.adb (Freeze_Record_Type): Extend the current management of
9436 components that are access type with an allocator as default value: add
9437 missing support to the use of qualified expressions of the
9438 allocator (which also cause freezing of the designated type!)
9439 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
9440 dispatching operation, since extra formals may be needed by calls to
9441 build-in-place functions (such as stream 'Input).
9443 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
9444 formals for 'Constrained and accessibility level in the case of a
9445 predefined dispatching operation.
9447 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
9448 point, no need to find the parent node.
9450 2007-08-16 Javier Miranda <miranda@adacore.com>
9452 * exp_attr.adb (Attribute_Priority): Add missing support for entries
9455 2007-08-16 Javier Miranda <miranda@adacore.com>
9457 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
9458 is not really required and can introduce regression with the debugger.
9459 The original problem is fixed with the patch written for checks.adb.
9461 2007-08-16 Thomas Quinot <quinot@adacore.com>
9463 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
9464 Range_Check on Allocated_Table.
9466 2007-08-16 Vincent Celier <celier@adacore.com>
9468 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
9469 Including_Non_Switch set to False.
9470 (Gnatmake): For the compiler, call Test_If_Relative_Path with
9471 Including_Non_Switch set to False.
9473 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
9474 parameter Including_Non_Switch, defaulted to True. When
9475 Including_Non_Switch is False, options that are not switches and
9476 appear as relative path are not converted to absolute paths.
9478 2007-08-16 Nicolas Roche <roche@adacore.com>
9480 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
9483 * Make-lang.in: Update dependencies

9488 currently inspected is a selected component, retrieve the entity of
9490 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
9491 from the immediate ancestor of Main_Unit_Entity.
9492 (Install_Limited_Withed_Unit): Do not install the limited view of
9493 package P if P is reachable through an ancestor chain from package C
9494 and C also has a with clause for P in its body.
9495 (Has_Limited_With_Clause): New routine.
9496 (Has_With_Clause): New routine.
9498 2007-08-16 Ed Schonberg <schonberg@adacore.com>
9500 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
9501 generic for an enclosing instance is a global reference, even though
9502 its scope is the enclosing instance.
9504 2007-08-16 Gary Dismukes <dismukes@adacore.com>
9505 Javier Miranda <miranda@adacore.com>
9507 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
9508 initialize a limited object.
9509 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
9511 Make sure Has_Complex_Representation is inherited by derived type.
9513 2007-08-16 Robert Dewar <dewar@adacore.com>
9515 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
9518 2007-08-16 Ed Schonberg <schonberg@adacore.com>
9520 * sem_disp.adb (Check_Dispatching_Operation): If the operation
9521 implements an operation inherited from a progenitor interface, verify
9522 that they are subtype-conformant.
9524 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
9525 Bob Duff <duff@adacore.com>
9526 Nicolas Setton <setton@adacore.com>
9528 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
9529 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
9530 the statement which is being resolved comes from a predefined library
9531 unit, all non-predefined library interpretations are skipped.
9532 (Resolve_Op_Concat): If string concatenation was folded in the parser,
9533 but the "&" is user defined, give an error, because the folding would
9536 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
9537 the parser has folded a long sequence of concatenations of string
9540 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
9541 and "JMP_BUF" variables as artificial.
9542 (N_String_Literal): Do not use alloca for very long string literals. Use
9543 xmalloc/free instead. Otherwise the stack might overflow.
9545 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
9548 2007-08-16 Vincent Celier <celier@adacore.com>
9550 * vms_conv.adb (Process_Argument): Ensure that project related options
9551 are not put in the -cargs section when using GNAT COMPILE.
9553 2007-08-16 Robert Dewar <dewar@adacore.com>
9555 * gnat_ugn.texi: Add note on preprocessing (output file not written)
9557 2007-08-16 Thomas Quinot <quinot@adacore.com>

9572 * a-calend-vms.adb, a-calend.adb ("+", "-", Add, Subtract): Remove
9573 calls to Check_Within_Time_Bounds.
9574 ("+", "-", Add, Subtract): Remove calls to Check_Within_Time_Bounds.
9575 (Difference): Account for possible rounding of the resulting difference

9581 s-osinte-solaris.adb, s-osinte-solaris.ads,
9582 s-osinte-freebsd.ads, s-osinte-freebsd.adb: Minor reformatting.

9585 switch -gnatyS. Enable -gnatyS in GNAT style check mode
9587 2007-08-14 Robert Dewar <dewar@adacore.com>
9588 Ed Schonberg <schonberg@adacore.com>
9590 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
9591 Suppress unmodified in-out parameter warning in some cases
9592 This patch is a also fairly significant change to the way suppressible
9595 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
9596 needed for access to concurrent record types generated by the expander.
9597 (Generate_Range_Check): When generating a temporary to capture the
9598 value of a conversion that requires a range check, set the type of the
9599 temporary before rewriting the node, so that the type is always
9600 properly placed for back-end use.
9601 (Apply_Float_Conversion_Check): Handle case where the conversion is
9603 (Get_Discriminal): Code reformatting. Climb the scope stack looking
9604 for a protected type in order to examine its discriminants.
9606 2007-08-14 Robert Dewar <dewar@adacore.com>
9607 Gary Dismukes <dismukes@adacore.com>
9608 Ed Schonberg <schonberg@adacore.com>
9609 Thomas Quinot <quinot@adacore.com>
9611 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
9612 a-stwisu.adb, a-strsup.adb: Fix warnings for range
9613 tests optimized out.
9615 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
9616 (Get_Allocator_Final_List): For the case of an anonymous access type
9617 that has a specified Associated_Final_Chain, do not go up to the
9619 (Expand_N_Type_Conversion): Test for the case of renamings of access
9620 parameters when deciding whether to apply a run-time accessibility
9622 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
9623 aggregate code before allocator, and ahead of declaration for
9624 temporary, to prevent access before elaboration when the allocator is
9625 an actual for an access parameter.
9626 (Expand_N_Type_Conversion): On an access type conversion involving an
9627 access parameter, do not apply an accessibility check when the
9628 operand's original node was an attribute other than 'Access. We now
9629 create access conversions for the expansion of 'Unchecked_Access and
9630 'Unrestricted_Access in certain cases and clearly accessibility should
9631 not be checked for those.
9633 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
9634 includes a type conversion of a packed component that has been expanded,
9635 recover the original expression for the object, and use this expression
9636 in the post-call assignment statement, so that the assignment is made
9637 to the object and not to a back-end temporary.
9638 (Freeze_Subprogram): In case of primitives of tagged types not defined
9639 at the library level force generation of code to register the primitive
9640 in the dispatch table. In addition some code reorganization has been
9641 done to leave the implementation clear.
9642 (Expand_Call): When expanding an inherited implicit conversion,
9643 preserve the type of the inherited function after the intrinsic
9644 operation has been expanded.
9646 * exp_ch2.ads, exp_ch2.adb
9647 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
9648 of an entry formal appearing in an assignment statement does not assign
9650 (Expand_Current_Value): Instead of calling a routine to determine
9651 whether the prefix of an attribute reference should be optimized or
9652 not, prevent the optimization of such prefixes all together.
9654 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
9655 component whose prefix is known to be of an access type is an implicit
9656 dereference and does not assign to the prefix.
9658 2007-08-14 Ed Schonberg <schonberg@adacore.com>
9659 Robert Dewar <dewar@adacore.com>
9661 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
9662 itype is visited, make an entry into table to link associated node and
9664 Add comments and correct harmless error in Build_NCT_Hash_Tables
9665 (Array_Aggr_Subtype): Associate each itype created for an index type to
9666 the corresponding range construct, and not to the aggregate itself. to
9667 maintain a one-to-one correspondence between itype and its associated
9668 node, to prevent errors when complex expression is copied.
9669 Fix mishandling of multiple levels of parens
9671 * sem_aggr.adb: Create a limited view of an incomplete type, to make
9672 treatment of limited views uniform for all visible declarations in a
9673 limited_withed package.
9674 (New_Copy_Tree): If hash table is being used and itype is visited,
9675 make an entry into table to link associated node and new itype.
9676 (Resolve_Record_Aggregate): Do not add an others box association for a
9677 discriminated record component that has only discriminants, when there
9678 is a box association for the component itself.
9680 * par-ch4.adb: Fix mishandling of multiple levels of parens
9682 2007-08-14 Robert Dewar <dewar@adacore.com>
9684 * comperr.adb: Fix problem with suppressing warning messages from gigi

9687 errout.adb (Write_Eol): Remove trailing spaces before writing the line
9688 (Write_Eol_Keep_Blanks): New procedure to write a line, including
9689 possible trailing spaces.
9690 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
9691 Fix problem with suppressing warning messages from back end
9692 Improve handling of deleted warnings
9695 Fix problem with suppressing warning messages from back end
9696 Handle setting of Static_Dispatch_Tables flag.
9699 Fix problem with suppressing warning messages from back end

9715 Javier Miranda <miranda@adacore.com>
9716 Gary Dismukes <dismukes@adacore.com>
9718 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
9719 to make treatment of limited views uniform for all visible declarations
9720 in a limited_withed package.
9721 Improve warnings for in out parameters
9722 (Set_Related_Interaface/Related_Interface): Allow the use of this
9723 attribute with constants.
9724 (Write_Field26_Name): Handle attribute Related_Interface in constants.
9725 Warn on duplicate pragma Preelaborable_Initialialization
9727 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
9728 generation of a freezing node to ensure proper management of null
9729 excluding access types in the backend.
9730 (Create_Extra_Formals): Test base type of the formal when checking for
9731 the need to add an extra accessibility-level formal. Pass the entity E
9732 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
9733 originally being done in a couple of cases), to ensure that the
9734 Extra_Formals list gets set on the entity E when the first entity is
9736 (Conforming_Types): Add missing calls to Base_Type to the code that
9737 handles anonymous access types. This is required to handle the
9738 general case because Process_Formals builds internal subtype entities
9739 to handle null-excluding access types.
9740 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
9741 functions that need it, even when not marked Requires_Overriding.
9742 Improve warnings for in out parameters
9743 (Analyze_Function_Return): Warn for disallowed null return
9744 Warn on return from procedure with unset out parameter
9745 Ensure consistent use of # in error messages
9746 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
9747 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
9748 the implicit conversion of the expression done for anonymous access
9749 types. This is required to generate the code of the null excluding
9750 check (if required).
9752 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
9753 A formal parameter is never publicly referenceable outside of its body.
9754 (Check_References): For an unreferenced formal parameter in an accept
9755 statement, use the same warning circuitry as for subprogram formal
9757 (Warn_On_Unreferenced_Entity): New subprogram, taken from
9758 Output_Unreferenced_Messages, containing the part of that routine that
9759 is now reused for entry formals as described above.
9760 (Goto_Spec_Entity): New function
9761 (Check_References): Do not give IN OUT warning for dispatching operation
9762 Improve warnings for in out parameters
9763 (Test_Ref): Check that the entity is not undefinite before calling
9764 Scope_Within, in order to avoid infinite loops.
9765 Warn on return from procedure with unset out parameter
9766 Improved warnings for unused variables

9770 Gary Dismukes <dismukes@adacore.com>
9772 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
9773 (Expand_N_Attribute_Reference): Further unify the handling of the
9774 three forms of access attributes, using common code now for all three
9775 cases. Add a test for the case of applying an access attribute to
9776 an explicit dereference when the context is an access-to-interface
9777 type. In that case we need to apply the conversion to the prefix
9778 of the explicit dereference rather than the prefix of the attribute.
9779 (Attribute_Version, UET_Address): Set entity as internal to ensure
9780 proper dg output of implicit importation.
9781 (Expand_Access_To_Type): Removed.
9782 (Expand_N_Attribute_Reference): Merge the code from the three cases
9783 of access attributes, since the processing is largely identical for
9784 these cases. The substantive fix here is to process the case of a
9785 type name prefix (current instance case) before handling the case
9786 of interface prefixes.

9790 Javier Miranda <miranda@adacore.com>
9791 Robert Dewar <dewar@adacore.com>
9793 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
9794 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
9795 type that is an anonymous access to controlled object, establish
9796 an associated finalization chain to avoid corrupting the global
9797 finalization list when a dynamically allocated object designated
9798 by such a component is deallocated.
9799 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
9800 functions that need it, even when not marked Requires_Overriding.

9806 Suppress_Initialization pragma for a derived type.
9807 (Is_Variable_Size_Record): New subprogram.
9808 (Build_Offset_To_Top_Functions): New implementation that simplifies the
9809 initial version of this routine and also fixes problems causing

9811 (Build_Init_Procedure): Improve the generation of code to initialize the
9812 the tag components of secondary dispatch tables.
9813 (Init_Secondary_Tags): New implementation that simplifies the previous

9818 diagnose attemps to freeze a subprogram when some untagged type of its
9819 profile is a private type whose full view has not been analyzed yet.
9820 (Freeze_Array_Type): Generate init proc for packed array if either
9821 Initialize or Normalize_Scalars is set.
9822 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
9823 constructing the new profile, copy the null_exclusion indicator for each
9824 parameter, to ensure full conformance of the new body with the spec.
9826 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
9827 Create wrappers for constructor functions that need it, even when not
9828 marked Requires_Overriding.

9868 output of implicit importation and exportation.
9869 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
9870 first formal of the thunk is always associated with the controlling
9871 type. In addition perform the following code cleanup: remove formal
9872 Thunk_Alias which is no longer required, cleanup evaluation of the
9873 the controlling type, and update the documentation.
9874 Replace occurrence of Default_Prim_Op_Count by
9875 Max_Predef_Prims. Addition of compile-time check to verify

9889 declaration of the primary tag that will be declared later by Make_DT.
9890 (Expand_Interface_Conversion): In case of access types to interfaces

9895 Ed Schonberg <schonberg@adacore.com>
9896 Javier Miranda <miranda@adacore.com>
9898 * exp_util.ads, exp_util.adb:
9899 This patch replaces a number of occurrences of explicit tests for N_Null
9900 with calls to Known_Null. This improves tracking of null values, since
9901 Known_Null also catches null constants, and variables currently known to
9902 be null, so we get better tracking.
9903 (Ensure_Defined): create an itype reference only in the scope of the
9905 (Side_Effect_Free): A selected component of an access type that
9906 denotes a component with a rep clause must be treated as not
9907 side-effect free, because if it is part of a linked structure its
9908 value may be affected by a renaming.
9909 (Expand_Subtype_From_Expr): For limited objects initialized with build
9910 in place function calls, do nothing; otherwise we prematurely introduce
9911 an N_Reference node in the expression initializing the object, which
9912 breaks the circuitry that detects and adds the additional arguments to
9913 the called function. Bug found working in the new patch for statically
9914 allocated dispatch tables.
9915 (Is_Library_Level_Tagged_Type): New subprogram.
9916 (Remove_Side_Effects): If the expression of an elementary type is an
9917 operator treat as a function call.
9918 (Make_Literal_Range): If the index type of the array is not integer, use
9919 attributes properly to compute the constraint on the resulting aggregate
9922 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
9923 class-wide type whose base type is an incomplete private type, leave
9924 class-wide type unfrozen so that freeze nodes can be generated
9925 properly at a later point.
9926 (Freeze_Entity, array case): Handle case of pragma Pack and component
9927 size attributre clause for same array.

10555 (Set_Item): When the new item is an element of the currently allocated
10556 table passed by reference, save a copy on the stack if we're going

10576 operations in Derive_Subprograms.
10577 (Collect_Previous_Instances): new procedure within of
10578 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
10579 unit being loaded, to ensure that the generation of global symbols is

10582 takes progenitor types into account.
10583 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
10584 traversing over the primitives of the formal and actual types to locate
10585 any abstract subprograms of the actual type that correspond to a
10586 nonabstract subprogram of the formal type's ancestor type(s), and issue
10587 an error if such is found.
10588 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
10589 Instantiate_Package_Body, Instantiate_Subprogram_Body):
10590 Remove bogus guard around calls to Inherit_Context.
10591 (Reset_Entity): If the entity is the selector of a selected component

10600 parameter to determine whether operation applies to the prefix.
10601 (Complete_Object_Operation): If actual has an access type and
10602 controlling formal is not an in_parameter, reject the actual if it is
10603 an access_to_constant type.
10604 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
10605 type, the candidate operations are found in the scope of declaration of
10606 the type, because the type has no primitive subprograms.
10607 (Analyze_Selected_Component): If prefix is class-wide, and root type is
10608 a private extension, only examine visible components before trying to
10609 analyze as a prefixed call.
10610 Change Entity_List to Type_To_Use, for better readability.
10611 (Has_Fixed_Op): Use base type when checking whether the type of an

10620 formal At_Any_Place indicating, when True, that we want to test for
10621 availability of the stream attribute at any place (as opposed to the
10622 current visibility context only).
10623 (Missing_Read_Write_Attributes): A stream attribute is missing for the
10624 purpose of enforcing E.2.2(8) only if it is not available at any place.
10625 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
10626 when checking the legality of an extension aggregate in a preelaborable
10627 package. Treat the literal null as a valid default expression in a
10628 component declaration for a type with preelaborable initialization.
10629 A limited interface is a legal progenitor for the designated type of a
10630 remote access to class-wide type.

10639 setting the Referenced_As_LHS flag for entities that are implicitly
10641 (Find_Type): If the type is an internally generated incomplete type,
10642 mark the full view as referenced, to prevent spurious warnings.
10643 (Find_Selected_Component, Has_Components): Handle properly non-limited
10644 views that are themselves incomplete types.
10645 Handle interfaces visible through limited-with clauses.
10646 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
10647 subprogram generic actual for which we have generated a renaming.
10648 Warn when the renaming introduces a homonym of
10649 the renamed entity, and the renamed entity is directly visible.

10655 appear in the subtree to the current allocator if it is not a static
10657 (Resolve_Allocator): Perform cleanup if resolution has determined that
10658 the allocator is not a coextension.
10659 (Resolve): Skip an interpretation hidden by an abstract operator only
10660 when the type of the interpretation matches that of the context.
10661 (Resolve): When looping through all possible interpretations of a node,
10662 do not consider those that are hidden by abstract operators.
10663 (Resolve_Actuals): When verifying that an access to class-wide object
10664 is an actual for a controlling formal, ignore anonymous access to
10665 subprograms whose return type is an access to class_wide type.
10666 (Resolve_Slice): If the prefix of the slice is a selected component
10667 whose type depends on discriminants, build its actual subtype before
10668 applying range checks on the bounds of the slice.
10669 (Valid_Conversion): In an instance or inlined body, compare root types,
10670 to prevent anomalies between private and public views.
10671 (Resolve): Improve error message for ambiguous fixed multiplication
10672 expressions that involve universal_fixed multiplying operations.

10692 elabration statements, register the package with the name server
10693 at the beginning, not at the end, of the elaboration statements so
10694 that they can create remote access to subprogram values that designate
10695 remote subprograms from the package.

10699 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
10700 values to compute the number of seconds since the Unix Epoc in order to

11843 Arnaud Charlet <charlet@adacore.com>
11845 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
11846 applicable to types that have the With_Type flag set. Returns the
11847 non-limited view of the type, if available, otherwise the type itself.
11848 For class-wide types, there is no direct link in the tree, so we have
11849 to retrieve the class-wide type of the non-limited view of the Etype.
11850 New attributes Static_Initialization and Static_Elaboration_Desired.
11851 Remove the pragma Thread_Body, and the associated flag
11852 Is_Thread_Body in entities, and all related code.

11865 (Original_Access_Type): Remove, not needed.
11866 (Root_Type): Handle properly subtypes of class-wide-types.
11869 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
11870 class-wide types visible through limited-with clauses.
11871 (Try_Primitive_Operation): When examining all primitive operations of a
11872 tagged type, do not consider subprograms labeled as hidden unless they
11873 belong to a private generic type with a tagged parent.
11874 (Try_Object_Operation): Extensive rewriting, to handle properly various
11875 overloading cases, when several ancestors may have class-wide operations
11876 that are possible candidates, and when the overloaded functions return
11877 array types and have defaulted parameters so that the call may be
11878 interpreted as an indexing.
11879 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
11880 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
11881 successive actuals before analyzing the call itself.
11882 (Try_Primitive_Operation): A primitive operation is compatible with the
11883 prefix if the prefix has a synchronized type and the type of the formal
11884 is its corresponding record, as can be the case when the primitive
11885 operation is declared outside of the body of the type.
11886 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
11887 perform homonym traversal, looking for class-wide operation matches
11888 (formerly done in statements of Try_Class_Wide_Operation). Matches on
11889 access parameters are now restricted to anonymous access types.
11890 (Mark_Allocator): An allocator with a discriminant association parent is
11892 (Try_One_Prefix_Interpretation): If the type of the object is
11893 incomplete, as can be happen when it is a limited view obtained through
11894 a limited_with_clause, the selected component is not part of a prefixed
11896 (Complete_Object_Operation): Diagnose properly an object that is not
11897 aliased when the corresponding controlling formal is an access
11899 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
11900 ambiguous calls in prefixed notation, where two primitives differ only
11901 in that the controlling argument of one is an access parameter.
11903 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
11904 whether a function that returns an unconstrained type can be inlined.
11905 (Process_Formals): Diagnose properly the illegal use of an incomplete
11906 type in the profile of an access_to_subprogram declaration.
11907 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
11908 operations are attached to the corresponding record.
11909 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
11910 When processing a primitive of a concurrent type which implements an
11911 interface change the type of all controlling formals to that of the
11912 corresponding record type.
11913 (Check_Synchronized_Overriding): Relax the conditional logic when trying
11914 to determine the tagged type to which a primitive belongs.
11915 (Check_Conventions): Capture condition to ignore a primitive operation
11916 (which is shared between the loop in Check_Conventions and the one in
11917 Check_Convention) in a new local function Skip_Check.
11918 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
11919 confusion with Check_Conventions' own Prim_Op local variable.
11920 (Create_Extra_Formals): Test for a tagged result type rather than a
11921 controlling result when determining whether to add a BIP_Alloc_Form
11922 formal and a BIP_Final_List formal to the function.
11923 (Check_Conformance); For parameters that are anonymous access types,
11924 subtype conformance requires that the not null and the constant
11925 indicators must match
11926 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
11927 to retrieve the appropriate type when processing a concurrent type
11928 declared within a generic. Minor comment reformatting. Change invocation
11929 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
11931 (Analyze_Subprogram_Body): If the return type of a function is an
11932 anonymous access to the limited view of a class-wide type, and the
11933 non-limited view of the type is available, update the type of the
11934 function so that code can be generated.
11935 (Process_Formals): In case of access-subtype itype whose designated
11936 type is also an itype (situation that happens now with access to
11937 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
11938 attribute to avoid backend problems.
11939 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
11940 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
11941 anonymous types' designated types are same before testing
11942 Subtypes_Statically_Match.
11943 (Create_Extra_Formals): Test for a named access parameter that is a
11944 controlling formal as an additional condition for adding an
11945 accessibility level formal. This can occur in the subp type created for
11946 dispatching calls in Expand_Dispatching_Call, and allows calling
11947 Create_Extra_Formals from that procedure rather than special-casing the
11948 extra formals there.
11949 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
11950 when the function has a controlling result.
11951 (Check_Returns): Add much more knowledge of the optimization of local
11952 raise statements to gotos, to retain proper warnings in this case.
11953 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
11954 nodes when looking for last statement.
11956 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
11957 class-wide types visible through limited with clauses.
11958 (Add_One_Interp): If the operands are anonymous access types, the
11959 predefined operator on universal_access is immediately visibles
11960 (Find_Unique_Type): Handle anonymous access to subprogram types just as
11961 other anonymous access types.
11962 (Disambiguate): Take into account CIL convention.
11963 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.

11984 in extension aggregates.
11985 (Flatten): Other conditions being met, an aggregate is static if the
11986 low bound given by component associations is different from the low
11987 bound of the base index type.
11988 (Packed_Array_Aggregate_Handled): If the component type is itself a
11989 packed array or record, the front-end must expand into assignments.
11990 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
11991 Init_Pr, instead of Ancestor_Is_Expression.
11992 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
11993 coextension chain root, either generate a list controller or use the
11994 already existing one.
11995 (Static_Array_Aggregate): New procedure to construct a positional
11996 aggregate that can be handled by the backend, when all bounds and
11997 components are compile-time known constants.
11998 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
11999 types covering interface types into assignments.
12000 (Replace_Type): move to Build_Record_Aggr_Code.
12001 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12002 interface type, convert to the definite type of the aggregate itself,
12003 so that needed components are visible.
12004 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12005 components and the context is an extended return statement do not
12006 create a transient block for it, to prevent premature finalization
12007 before the return is executed.
12008 (Gen_Assign): Do not generate a call to deep adjust routine if the
12009 component type is itself an array of controlled (sub)-components
12010 initialized with an inner aggregate.
12011 (Component_Check): New name for Static_Check. This name is now more
12012 appropriate, and documentation is added which was missing.
12013 (Component_Check): Add test for bit aligned component value
12014 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12015 Tagged_Comps, name is more appropriate given added function below.
12016 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

12022 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12023 Terminated: Add unchecked type conversion from System.Address to
12024 System.Tasking.Task_Id when calling the predefined primitive
12026 Disable new Ada 05 accessibility check for JVM.NET targets, which
12027 cannot be implemented in a practical way.
12028 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12029 the sources always references the tag of the actual object. Therefore,
12030 if 'Tag is applied in the sources to class-wide interface objects we
12031 generate code that displaces "this" to reference the base of the object.
12032 (Expand_N_Attribute_Reference, case Size): Return specified size if
12033 known to front end.
12034 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12035 has code that displaces the pointer of the object to manage interface
12036 types. However this code must not be executed when the prefix is a
12037 subprogram. This bug caused the wrong expansion of the internally
12038 generated assignment that fills the dispatch table when the primitive
12039 is a function returning a class-wide interface type.
12040 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12041 Set_Attribute_Name for Name_Unaligned_Valid.

12044 Gary Dismukes <dismukes@adacore.com>
12046 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12047 If the initialization is the equivalent aggregate of the initialization
12048 procedure of the type, do not remove it.
12049 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12050 initialized to null from having their expression reset to empty and
12051 note this exception in the comment.

12059 Add "with" and "use" clauses for Sem_Attr.
12060 (Expand_Current_Value): Do not replace occurences of attribute
12061 references where the prefix must be a simple name.
12063 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
12064 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
12065 Attribute_Requires_Simple_Name_Prefix.
12066 (Name_Modifies_Prefix): Body of new function.
12067 (Requires_Simple_Name_Prefix): Body of new function.
12068 (Resolve_Attribute, case Access): Improve error message for case of
12069 mismatched conventions.
12070 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
12072 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12073 constrained subtype for a nominal unconstrained type, use its base type
12074 to check for conformance with the context.
12075 (Resolve_Attribute): Remove test of the access type being associated
12076 with a return statement from condition for performing accessibility
12077 checks on access attributes, since this case is now captured by
12078 Is_Local_Anonymous_Access.
12079 (Analyze_Access_Attribute): Set Address_Taken on entity
12080 (Analyze_Attribute, case Address): Set Address_Taken on entity
12081 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
12082 validating an access attribute whose prefix is a current instance.
12083 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
12084 applied to dispatching operations, if freezing is required then we set
12085 the attribute Has_Delayed_Freeze in the prefix's entity.
12086 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
12087 current scope if access of local subprogram taken
12088 (Analyze_Access_Attribute): Check legality of self-reference even if the
12089 expression comes from source, as when a single component association in
12090 an aggregate has a box association.
12091 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
12092 the prefix if it is a protected operation and the attribute is
12093 Unrestricted_Access.
12094 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
12095 reference to the base type of the context, to force a constraint check
12096 when the context is an access subtype with an explicit constraint.
12097 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
12098 node is rewritten as an interface conversion. leave unanalyzed after
12099 resolution, to ensure that type checking against the context will take

12103 Javier Miranda <miranda@adacore.com>
12104 Robert Dewar <dewar@adacore.com>
12106 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
12107 wrapper when the full view of the controlling type of an inherited
12108 function that dispatches on result implements interfaces.
12109 (Expand_N_Object_Declaration): In cases where the type of the
12110 declaration is anonymous access, create finalization list for it.
12111 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
12112 if the object has no explicit initialization, to match description of
12113 functionality of pragam Persistent_BSS.
12114 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
12115 new function to build static aggregates, to replace initialization call
12116 when static initialization is desired.
12117 (Freeze_Type): Generate a list controller for an access type whenever
12118 its designated type has controlled anonymous access discriminants.
12119 (Build_Equivalent_Aggregate): New procedure to compute a static
12120 aggregate to be used as default initialization for composite types,
12121 instead of a generating a call to the initialization procedure for the
12123 (Build_Initialization_Call): When available, replace a call to the
12124 initialization procedure with a copy of the equivalent static aggregate
12126 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
12127 declarations for objects of a class-wide interface type, rather than
12128 just identifiers, to prevent visibility problems.
12129 (Expand_N_Object_Declaration): When expanding the declaration for an
12130 object of a class-wide interface type, preserve the homonym chain of
12131 the original entity before exchanging it with that of the generated
12132 renaming declaration.
12133 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
12134 active, because there is no way to handle the exception.
12135 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
12136 to do a minimum decoration of the Access_Disp_Table list.
12137 (Expand_Record_Controller): Avoid the addition of the controller between
12138 the component containing the tag of a secondary dispatch table and its
12139 adjacent component that stores the offset to the base of the object.
12140 This latter component is only generated when the parent type has
12141 discriminants ---documented in Add_Interface_Tag_Components).
12142 (Apply_Array_Size_Check): Removed, no longer needed.
12143 (Expand_N_Full_Type_Declaration): If the type has anonymous access
12144 components, create a Master_Entity for it only if it contains tasks.
12145 (Build_Init_Procedure): Suppress the tag assignment compiling under
12147 (Freeze_Record_Type): Remove code associated with creation of dispatch
12149 (Init_Secondary_Tags): Update type of actuals when generating calls to
12150 Ada.Tags.Set_Offset_To_Top
12151 (Stream_Operation_OK): Disable use of streams compiling under no
12153 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
12154 if Has_Init_Expression set.
12155 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
12156 Register_Primitive, which provides the same functionality.
12157 (Requires_Init_Proc): Return false in case of interface types.
12158 (Add_Secondary_Tables): Use the new attribute Related_Interface to
12160 (Predefined_Primitive_Freeze): Do not assume that an internal entity
12161 is always associated with a predefined primitive because the internal
12162 entities associated with interface types are not predefined primitives.
12163 Therefore, the call to Is_Internal is replaced by a call to the
12164 function Is_Predefined_Dispatching_Operation.
12165 (Make_Eq_If): When generating the list of comparisons for the
12166 components of a given variant, omit the controller component that is
12167 present if the variant has controlled components.

12170 Hristian Kirtchev <kirtchev@adacore.com>
12171 Bob Duff <duff@adacore.com>
12173 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
12174 handle the creation of finalization lists and calls for nested
12175 coextensions when the root of the chains is part of a return statement.
12176 (Inside_A_Return_Statement): New function inside Complete_Coextension_
12178 (Expand_Record_Equality): Skip components that are interface types.
12179 (Displace_Allocator_Pointer): Add missing support for interface subtypes
12180 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
12181 with Rewrite_Coextension. Change the condition for detecting coextension
12183 (Is_Local_Access_Discriminant): Removed.
12184 (Rewrite_Coextension): New routine which rewrites a static coextension
12185 as a temporary and uses its unrestricted access in the construction of
12187 (Complete_Coextension_Finalization): New routine. Generate finalization
12188 attachment calls to all delayed coextensions.
12189 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
12190 the allocator is not a coextension itself and has delayed coextensions.
12191 If the current allocator is controlled, but also a coextension, delay
12192 the generation of the finalization attachment call.
12193 Rename local variable "Node" to "Nod" in order to avoid confusion with
12195 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
12196 limited types that are not inherently limited. Such an allocator is
12197 illegal, but is generated by the expander for a return statement, to
12198 copy the result onto the secondary stack. This is the only case where a
12199 limited object can be copied. Generate code to displace the pointer
12200 to the object if the qualified expression is a class-wide interface
12201 object. Such displacement was missing and hence the copy of the object
12203 (Apply_Accessibility_Check): Handle allocated objects initialized in
12205 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
12206 and Expand_Allocator_Expression. Allocating class-wide interface objects
12207 this routine displaces the pointer to the allocated object to reference
12208 the component referencing the corresponding secondary dispatch table.
12209 Expand_Allocator_Expression): Add missing support to allocate class-wide
12210 interface objects initialized with a qualified expression.
12211 (Get_Allocator_Final_List): Test for an anonymous access type that is a
12212 function result type, and use the finalization list associated with the
12213 function scope in that case (such an anonymous type should not be
12214 treated like an access parameter's type).

12217 Gary Dismukes <dismukes@adacore.com>
12218 Javier Miranda <miranda@adacore.com>
12220 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
12221 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
12222 required exception handler.
12223 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
12224 properly the case of a function whose return type is a limited
12225 class-wide interface type. Modify the code of the accessibility
12226 check to handle class-wide interface objects. In this case we need to
12227 displace "this" to reference the primary dispatch table to get access
12228 to the TSD of the object (to evaluate its accessibility level).
12229 (Expand_N_Extended_Return_Statement): Test for a tagged result type
12230 rather than a controlling result as one of the conditions for
12231 generating tests of the implicit BIP_Alloc_Form formal. The
12232 initialization assignment is also handled according to whether the
12233 result is tagged instead of controlling.
12234 In the case where the init assignment is inserted in the "then" part of
12235 the allocation conditional, rewrite the target to be a dereference of
12236 the implicit BIP_Object_Access formal.
12237 If the returned value is unconstrained and created on the secondary
12238 stack, mark the enclosing block and function so that the secondary
12239 stack is not reclaimed on return.
12240 Treat returns from functions with controlling results similarly to
12241 returns from functions with unconstrained result subtypes.
12242 If the object returned is unconstrained, and an allocator must be
12243 created for it, analyze the allocator once the block for the extended
12244 return is installed, to ensure that finalizable components
12245 of the expression use the proper finalization list. Guard the call to
12246 Move_Final_List with a check that there is something to finalize.
12247 (Make_Tag_Ctrl_Assignment): Use "old" handling
12248 of controlled type assignment for virtual machines, since new code uses
12249 unsupported features (such as direct access to bytes in memory).
12251 2007-06-06 Gary Dismukes <dismukes@adacore.com>
12252 Ed Schonberg <schonberg@adacore.com>
12254 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
12255 accessibility actual, check for the case of an aliased object that has
12256 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
12257 we fall into processing for the attribute rather than the name of the
12259 (Expand_Inline_Call): If an actual is a literal, and the corresponding
12260 formal has its address taken in the body, create a temporary to capture
12261 value. If the return type is a limited interface, do not treat the
12262 return value as Controlled.
12263 (Is_In_Place_Function): If the return type is a limited interface,
12264 treat as returning in place. The actual returned object may not always
12265 be limited, but the caller has to assume that it is returned in place.
12266 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
12267 context of an allocator, use the correct finalization chain (that is,
12268 the chain belonging to the access type, rather than the chain belonging
12269 to the current scope).
12270 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
12271 result type rather than a controlling result as a precondition for
12272 adding an allocation form actual to a build-in-place call.
12273 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
12274 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
12275 primitive in the dispatch tables. This work is now done by Make_DT when
12276 the type is frozen.
12277 (Register_Predefined_DT_Entry): Removed.
12278 (Add_Return): If end label is not present, use sloc of last statement
12279 for generated return statement in procedure, for better gdb behavior
12281 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
12282 object address nodes to ensure proper processing by routines like
12284 (Expand_Call): Fix generation of validity check for parameter
12285 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
12286 the allocation form parameter if the result subtype is constrained,
12287 except when the function has a controlling result.
12288 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
12289 rather than Is_Controlled and Has_Controlled_Component, since we want to
12290 include class-wide result types in this treatment. Also test for a
12291 controlling result, since that also requires passing a finalization
12293 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
12294 even when the result subtype is constrained, to handle calls involving
12295 controlling results.
12296 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
12297 is now called even when the result subtype is constrained, to handle
12298 calls involving controlling results.
12299 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
12300 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
12301 now performs the test).
12302 (Make_Build_In_Place_Call_In_Object_Declaration):
12303 Add_Alloc_Form_Actual_* is now called even when the result subtype is
12304 constrained, to handle calls involving controlling results.
12305 (Add_Return): Accomodate rewritten pattern from local raise to goto
12306 transformation, so that we still recognize an transfer statement
12307 and do the right thing here in that case.
12308 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
12309 and end of subprogram code.
12310 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
12311 support for primitives that are functions (without formals) with a
12312 controlling result.
12313 (Inherited_From_Formal): If the actual subtype has not generic parent
12314 type, it is not an actual for a formal derived type, and there is no
12315 operation to inherit from the formal.

12318 Thomas Quinot <quinot@adacore.com>
12320 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
12321 inserted cleanup code appropriately for GDB use.
12322 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
12323 exception handler for Deep_Adjust or Deep_Finalize.
12324 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
12325 Raise_From_Controlled_Operation is available, use a call to that
12326 subprogram instead of a plain "raise Program_Error" node to raise
12327 Program_Error if an exception is propagated from an Adjust or Finalize
12329 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
12330 appears in the optional statement list of a triggering alternative, the
12331 scope actions can be inserted directly there, and not in the list that
12332 includes the asynchronous select itself.
12334 2007-06-06 Ed Schonberg <schonberg@adacore.com>

12336 Hristian Kirtchev <kirtchev@adacore.com>
12338 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
12339 generated exception handler appropriately when debugging generated code.
12340 Deal properly with No_Exception_Propagation restriction mode.
12341 (Expand_N_Abort_Statement): Add an unchecked type conversion from
12342 System.Address to System.Tasking.Task_Id when processing the result of
12343 the predefined primitive _disp_get_task_id.
12344 (Expand_N_Asynchronous_Select): Clarify comment.
12345 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
12346 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
12347 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
12348 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
12349 privals and for generated call to Complete_Entry_Body, for better gdb
12351 (Copy_Result_Type): Utility to construct a parameter and result profile
12352 for protected functions whose return type is an anonymous access to
12354 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
12356 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
12357 point when the local-raise-to-goto transformation has taken place.
12359 2007-06-06 Javier Miranda <miranda@adacore.com>
12360 Nicolas Setton <setton@adacore.com>
12362 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
12363 functionality when the backend is generating code.
12364 Otherwise any serious error
12365 reported by the backend calling the frontend routine Error_Msg
12366 changes the Compilation_Mode to Check_Semantics, disables the
12367 functionality of this routine and causes the generation of
12368 spureous additional errors.
12370 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
12371 debugging information now generated by the compiler for fat-pointer
12373 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
12375 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
12377 2007-06-06 Thomas Quinot <quinot@adacore.com>
12379 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
12380 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
12381 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
12382 For a remote call to a function with a classwide return type, apply an
12383 E.4(18) check to the returned value.
12384 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
12385 stream attributes of the designated type of an RACW, as they are not
12386 dispatching primitive operations.
12388 2007-06-06 Geert Bosch <bosch@adacore.com>
12390 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
12392 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
12394 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
12395 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
12397 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
12399 2007-06-06 Javier Miranda <miranda@adacore.com>
12401 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
12402 attribute compiling package Ada.Tags under No_Run_Time_Mode.
12404 2007-06-06 Javier Miranda <miranda@adacore.com>
12406 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
12407 deallocation of class-wide interface objects.
12408 (Expand_Dispatching_Constructor_Call): Take into account that if the
12409 result of the dispatching constructor is an interface type, the
12410 function returns a class-wide interface type; otherwise the returned
12411 object would be actual. The frontend previously accepted returning
12412 interface types because Expand_Interface_Actuals silently performed
12413 the management of the returned type "as if" it were a class-wide
12415 (Expand_Dispatching_Constructor_Call): Replace call to
12416 Make_DT_Access_Action by direct call to Make_Function_Call.
12418 2007-06-06 Robert Dewar <dewar@adacore.com>
12419 Ed Schonberg <schonberg@adacore.com>

12509 (Side_Effect_Free): An expression that is the renaming of an object or
12510 whose prefix is the renaming of a object, is not side-effect free

13036 associated with dispatch tables is known at compile time.
13037 (Get_Value): If an association in a record aggregate has a box
13038 association, and the corresponding record component has a default
13039 expression, always copy the default expression, even when the

14241 (E_Return_Statement): This node type has the Finalization_Chain_Entity
14242 attribute, in case the result type has controlled parts.
14243 (Requires_Overriding): Add this new flag, because "requires
14244 overriding" is subtly different from "is abstract" (see AI-228).
14245 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
14246 Is_Abstract_Type. Make sure these are called only when appropriate.

14308 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
14309 "abstract subprograms must be visible" message, whether or not the type

14336 build-in-place functions with result type with controlled parts.
14337 Remove no longer used entities.
14339 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
14340 longer needed, because the full type is now limited, and therefore a
14341 pass-by-reference type.
14342 (Foreign_Task_Level): New constant.
14344 * s-tassta.ads, s-tassta.adb (Move_Activation_Chain): New procedure to

14379 "X'Unrestricted_Access = Y'Access" and so forth to match.
14380 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,

14387 attempt to derive from a synchronized tagged type.
14388 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
14389 type, inherit the class-wide type already created, because it may
14390 already have been used in a self-referential anonymous access component.

14392 that use (a subtype of) the class-wide type of the enclosing type.
14393 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
14394 Derived_Type for Prev formal on call to
14395 Check_Anonymous_Access_Components rather than Empty.
14396 (Make_Incomplete_Type_Declaration): Add test for case where the type has
14397 a record extension in deciding whether to create a class-wide type,

14445 (Compile): When compiling a predefined source, add -gnatpg
14446 as the second switch, after -c.
14447 (Compile_Sources): Allow compilation of Annex J renames without -a

14451 gnatbind if the ALI file effectively exists.
14452 (Initialize): Add the directory where gnatmake is invoked in front of
14453 the path if it is invoked from a bin directory, even without directory

14478 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
14479 when -gnatg is not specified.
14480 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
14481 there is no need to generate always a record_definition_node in case
14482 of synchronized interface types.

14509 (Convert_Aggr_In_Allocator): If the allocator is for an access
14510 discriminant and the type is controlled. do not place on a finalization
14511 list at this point. The proper list will be determined from the

14531 parameter of the containing subprogram.
14532 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
14533 under No_Dispatching_Calls restriction. During the semantic analysis
14534 we already notified such violation.

14553 Modify the declaration of the object containing the TSD
14554 because we now expand code that has a higher level of abstraction.
14555 The TSD has a discriminant containing the Inheritance Depth Level,
14556 value that is used in the membership test but also to fix the size
14557 of the table of ancestors.
14558 (Expand_Interface_Conversion): Insert function body at the closest place
14559 to the conversion expression, to prevent access-before-elaboration

14616 support concurrent types implementing interfaces.
14617 (Find_Implemented_Interface): Removed. All the calls to this subprogram

14621 CW_Or_Controlled_Type whenever the issue is related to
14622 using or not the secondary stack.

14660 (Build_Entry_Count_Expression): If the family is potentially large, call
14661 Family_Size with 'Cap' set to true.
14662 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
14663 a protected version of an operation declared in the private part of
14664 a protected object, because they may be invoked through a callback.
14665 (Set_Privals): If the type of a private component is an anonymous access
14666 type, do not create a new itype for each protected body.
14667 If the body of a protected operation creates
14668 controlled types (including allocators for class-widetypes), the
14669 body of the corresponding protected subprogram must include a
14671 (Build_Activation_Chain_Entity): Build the chain entity for extended
14673 (Type_Conformant_Parameters): Use common predicate Conforming_Types
14674 to determine whether operation overrides an inherited primitive.
14675 (Build_Wrapper_Spec): Add code to examine the parents while looking
14676 for a possible overriding candidate.
14677 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
14678 hold an actual parameter value since its initialization is separated
14679 from the the declaration. Prevents errors on null-excluding access

14683 Pablo Oliveira <oliveira@adacore.com>
14685 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
14686 Do an Unchecked_Conversion to handle the passage from the Underlying
14687 Type to the Base Type when calling Build_To_Any_Call and
14688 Build_From_Any_Call.
14689 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
14690 E_Constant, depending upon Variable formal.
14691 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14692 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
14693 parameter that requires an extra constrained parameter, declare
14694 temporary for actual as a variable, not a constant.
14695 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
14696 the unit being compiled is the one that contains the stub type.
14697 Change primitive operation name for the RACW associated with a RAS
14698 from Call to _Call so it cannot clash with any legal identifier.
14699 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
14701 (Append_RACW_Bodies): New subprogram.
14702 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
14703 Add_Receiving_Stubs_To_Declarations functions.
14704 When expanding a package body, this list correspond to the
14705 statements in the HSS at the end of the pacakge.
14706 When expanding a package spec, this list correspond to the
14708 (Add_Receiving_Stubs_To_Declarations): Append the function
14709 registering the receiving stubs at the end of the 'Stmts' list.
14710 (RCI_Package_Locator): Pass the new Version generic formal when
14711 instantiating a RCI_Locator package.
14712 (Build_From_Any_Function): To compute the High bound for an
14713 unconstrained array actual, we add the Low bound with the length.
14714 Thus we must convert the low bound and the length to an appropriate
14715 type before doing the sum.
14716 (Build_Subprogram_Receiving_Stubs, PolyORB):
14717 * Retrieve the extra formals parameters at the
14718 end of the parameter stream.
14719 * Use Move_Any_Value to write back out parameters
14720 after executing the request as it is more efficient
14721 than Copy_Any_Value.
14722 * Build the any containing Extra Formals with the
14723 appropriate typecode.
14724 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
14725 empty Component_List.
14726 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
14727 the tree the declaration for an object that serves as actual parameter
14728 in server-side stubs.
14729 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14730 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
14731 Use Build_Actual_Object_Declaration to prepare the actuals.

14733 Extra Constrained Parameters.
14734 (Build_General_Calling_Stubs): Set the parameter type to boolean for

14738 function with the first not implicit parent type.
14739 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
14740 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
14741 typecode from the Etype. Therefore we retrieve the correct typecode
14742 with a call to Get_Any_Type.
14743 (Copy_Specification): Do controlling formal type substitution based on
14744 Is_Controlling_Formal flag, instead of caller-provided object type.
14745 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
14746 a RACW primitive operation, we might get a subprogram declaration for an
14747 ancestor of the RACW designated type (not for the designated type
14748 itself), in the case where this operation is inherited. In this case we
14749 have no easy means of determining the original tagged type for which
14750 the primitive was declared, so instead we now rely on
14751 Copy_Specification to use the Is_Controlling_Formal flag to determine
14752 which formals require type substitution.

14758 GNAT.Current_Exception are not allowed if pragma Restrictions
14759 (No_Exception_Propagation) is set and in any case make the associated
14760 handler unsuitable as a target for a local raise statement.
14761 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
14762 run-time subprogram CW_Membership by call to Build_CW_Membership.
14763 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
14764 by a function call, a temporary must be created before expanding the
14765 Constructor_Call itself, to prevent out-of-order elaboration in the
14766 back-end when stack checking is enabled..
14768 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14770 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
14771 result are the bounds of the left operand, not the right.
14773 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14776 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

14895 standard 8bits encoding.
14896 (WS2SU): As above but converting from wide-sring to string.
14897 This is needed as it is necessary to have access to both versions in the
14898 runtime for the form parameter encoding support.
14899 This set of patch add support for the encoding form parameter.
14900 (S2WS): Improve implementation to handle cases where the filename is not

14950 __gnat_adjust_context_for_raise.
14951 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
14952 implementation of floating point operations as native x86 targets.
14953 So the FPU should be initialized in the same way using finit. Fix
14954 floating point operations accuracy issues.
14955 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
14956 member in struct sigaction, so as to avoid warning for incompatible

15123 the default project path, initially done during elaboration of the
15125 If the prefix returned by Sdefault is null, get the prefix from a call
15126 to Executable_Prefix_Path.
15127 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
15130 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
15131 canonical directory name to open the directory from which files are
15133 (Record_Other_Sources): Idem.
15134 (Locate_Directory): Add the possibility to create automatically missing
15135 directories when Setup_Projects is True.
15136 Call Locate_Directory so that the directory will be created when
15137 Setup_Projects is True, for object dir, library dir, library ALI dir,
15138 library source copy dir and exec dir.
15140 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
15143 2007-04-06 Robert Dewar <dewar@adacore.com>
15145 * sem_ch13.ads, sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
15146 Use First/Next_Component_Or_Discriminant
15147 (Analyze_Record_Representation_Clause):
15148 Use First/Next_Component_Or_Discriminant
15149 (Check_Component_Overlap): Use First/Next_Component_Or_Discriminant
15150 (Analyze_Attribute_Definition_Clause, case Value_Size): Reject
15151 definition if type is unconstrained.
15152 (Adjust_Record_For_Reverse_Bit_Order): New procedure
15153 (Analyze_Attribute_Definition_Clause): Split Is_Abstract flag into
15154 Is_Abstract_Subprogram and Is_Abstract_Type.
15155 (Adjust_Record_For_Reverse_Bit_Order): New procedure
15157 * repinfo.adb (List_Record_Info): Use First/
15158 Next_Component_Or_Discriminant.
15160 * style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
15163 * stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch
15164 Include -gnatyA in default switches
15166 * opt.ads: (Warn_On_Non_Local_Exception): New flag
15167 (Warn_On_Reverse_Bit_Order): New flag
15168 (Extensions_Allowed): Update the documentation.
15169 (Warn_On_Questionable_Missing_Parens): Now on by default
15171 * usage.adb: Add documentation of -gnatw.x/X switches
15172 Document new -gnatyA style switch
15173 -gnatq warnings are on by default
15175 2007-04-06 Ed Falis <falis@adacore.com>
15177 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
15178 full word is no longer compared twice.
15180 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15182 * sem_ch10.adb (Install_Limited_Context_Clauses.
15183 Expand_Limited_With_Clause): Use a new copy of selector name in the
15184 call to Make_With_Clause. This fixes the tree structure for ASIS
15185 purposes. Nothing is changed in the compiler behaviour.
15186 (Process_Body_Clauses): Handle properly use clauses whose prefix is
15187 a package renaming.
15188 (Install_Limited_With_Clauses): Do not install non-limited view when it
15189 is still incomplete.
15191 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15192 Gary Dismukes <dismukes@adacore.com>
15194 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
15195 when capturing size information, instead of base type, which for a
15196 formal array type will be the unconstrained type.
15197 (Analyze_Formal_Object_Declaration): Add check for illegal default
15198 expressions for a formal in object of a limited type.
15199 (Instantiate_Object): Ditto.
15200 (Check_Formal_Package_Instance): Skip entities that are formal objects,
15201 because they were defaulted in the formal package and no check applies
15203 (Check_Formal_Package_Instance): Extend conformance check to other
15204 discrete types beyond Integer.
15205 (Process_Default): Copy directly the unmatched formal. A generic copy
15206 has already been performed in Analyze_Formal_Package.
15207 (Analyze_Associations): If a formal subprogram has no match, check for
15208 partial parametrization before looking for a default, to prevent
15210 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
15211 not set the instantiation environment before analyzing the actuals.
15212 Fixes regression on 8515-003 with implementation of AI-133.
15213 Set_Instance_Env checks whether the generic unit is a predefined
15214 unit, in which case the instance must be analyzed with the latest Ada
15215 mode. This setting must take place after analysis of the actuals,
15216 because the actuals must be analyzed and frozen in the Ada mode extant
15217 outside of the current instantiation.
15218 (Save_Env, Restore_Env): Preserve and restore the configuration
15219 parameters so that predefined units can be compiled in the proper Ada
15221 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
15222 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
15223 and Is_Abstract_Type.
15224 (Analyze_Formal_Package): For better error recovery, Add exception
15225 handler to catch Instantion_Error, which can be raised in
15226 Analyze_Associations
15228 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15229 Bob Duff <duff@adacore.com>
15230 Gary Dismukes <dismukes@adacore.com>
15232 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
15233 prefix type is a discriminated subtype of the type of the formal.
15234 (Analyze_Allocator): Collect all coextensions regardless of the context.
15235 Whether they can be allocated statically is determined in exp_ch4.
15236 (Analyze_Selected_Component): If the prefix is a limited view and the
15237 non-limited view is available, use the non-limited one.
15238 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
15239 therefore illegal), suggest a qualified expression rather than a type
15240 conversion, because a type conversion would be illegal in this context.
15241 (Anayze_Allocator): Trace recursively all nested allocators so that all
15242 coextensions are on the corresponding list for the root. Do no mark
15243 coextensions if the root allocator is within a declaration for a stack-
15244 allocated object, because the access discriminants will be allocated on
15246 (Analyze_Call): Remove restriction on calls to limited functions for the
15247 cases of generic actuals for formal objects, defaults for formal objects
15248 and defaults for record components.
15249 (Analyze_Allocator): Before analysis, chain coextensions on the proper
15250 element list. Their expansion is delayed until the enclosing allocator
15251 is processed and its finalization list constructed.
15252 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
15253 for an operation with the given name among the primitive operations of
15254 the corresponding record type.
15255 (Analyze_Selected_Component): If the prefix is a task type that
15256 implements an interface, and there is no entry with the given name,
15257 check whether there is another primitive operation (e.g. a function)
15259 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
15260 properly the indexing of a function call written in prefix form, where
15261 the function returns an array type, and all parameters of the function
15262 except the first have defaults.
15263 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
15264 the original operands, rather than relocating them, for efficiency and
15265 to work properly when an operand is overloaded.
15266 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
15267 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
15268 (Analyze_Selected_Component): If the prefix is a private extension, only
15269 scan the visible components, not those of the full view.
15270 (Try_Primitive_Operation): If the operation is a procedure, collect all
15271 possible interpretations, as for a function, because in the presence of
15272 classwide parameters several primitive operations of the type can match
15273 the given arguments.
15275 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15276 Robert Dewar <dewar@adacore.com>
15278 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
15279 tag-indeterminate call to an abstract function, when the left-hand side
15281 (Analyze_Loop_Statement): Improve detection of infinite loops
15283 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15284 Thomas Quinot <quinot@adacore.com>
15286 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
15287 out of Analyze_Package_Declaration, because processing must be applied
15288 to package bodies as well, for deferred constants completed by pragmas.
15289 (Analyze_Package_Declaration): When the package declaration being
15290 analyzed does not require an explicit body, call Check_Completion.
15291 (May_Need_Implicit_Body): An implicit body is required when a package
15292 spec contains the declaration of a remote access-to-classwide type.
15293 (Analyze_Package_Body): If the package contains RACWs, append the
15294 pending subprogram bodies generated by exp_dist at the end of the body.
15295 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
15296 Is_Abstract_Subprogram and Is_Abstract_Type.
15297 (Preserve_Full_Attributes): The full entity list is not an attribute
15298 that must be preserved from full to partial view.
15300 * sem_dist.adb (Add_RAS_Dereference_TSS):
15301 Change primitive name to _Call so it cannot clash with any legal
15302 identifier, and be special-cased in Check_Completion.
15303 Mark the full view of the designated type for the RACW associated with
15304 a RAS as Comes_From_Source to get proper view switching when installing
15305 private declarations.
15306 Provite a placeholder nested package body along with the nested spec
15307 to have a place for Append_RACW_Bodies to generate the calling stubs
15308 and stream attributes.
15310 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15311 Robert Dewar <dewar@adacore.com>
15313 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
15314 that is a limited view, check the non-limited view if available.
15315 (Undefined): Refine error message for missing with of Text_IO
15316 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
15317 to distinguish real missing with cases.
15318 Fix format of all missing with messages
15319 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
15320 renaming as body when renamed entity is abstract.
15322 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15323 Javier Miranda <miranda@adacore.com>
15325 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
15326 predicate recursive, to handle complex expressions on literals whose
15327 spurious ambiguity comes from the abstract interpretation of some
15329 (Interface_Present_In_Ancestor): Add support to concurrent record
15331 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
15332 Is_Abstract_Subprogram and Is_Abstract_Type.
15334 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15335 Javier Miranda <miranda@adacore.com>
15337 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
15338 dereference of a local object R created as a reference to another
15339 object O, use the access level of O.
15340 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
15341 rather than local Same_Formal_Type, to check whether protected operation
15342 overrides an inherited one.
15343 (Same_Formal_Type): New predicate, used when matching signatures of
15344 overriding synchronized operations, to handle the case when a formal
15345 has a type that is a generic actual.
15346 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
15347 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
15348 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
15349 syntactic ambiguities involving indexing of function calls that return
15351 (Abstract_Interface_List): New subprogram that returns the list of
15352 abstract interfaces associated with a concurrent type or a
15353 concurrent record type.
15354 (Interface_Present_In_Parent): New subprogram used to check if a
15355 given type or some of its parents implement a given interface.
15356 (Collect_Abstract_Interfaces): Add support for concurrent types
15357 with interface types.
15358 (Has_Abstract_Interfaces): Add support for concurrent types with
15360 (Is_Parent): New subprogram that determines whether E1 is a parent
15361 of E2. For a concurrent type its parent is the first element of its
15362 list of interface types; for other types this function provides the
15363 same result than Is_Ancestor.
15364 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
15365 (Collect_Synchronized_Interfaces): Removed because the subprogram
15366 Collect_Abstract_Interfaces provides this functionality.
15367 (Collect_Abstract_Interfaces): Minor update to give support to
15368 concurrent types and thus avoid undesired code duplication.
15369 (Get_Subprogram_Entity): Handle entry calls.
15370 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
15372 (Enter_Name): Do not give -gnatwh hiding warning for record component
15373 entities, they never result in hiding.

15388 can be an E_Return_Statement.
15389 (Is_Coextension): New flag for allocators.

15408 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
15409 expression with a COMPOUND_EXPR including the call instead of emitting
15410 the call directly here.
15411 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
15412 high bound is constant and the slice is empty. Tidy.
15413 (tree_transform, case N_Op_Not): Handle properly the case where the
15414 operation applies to a private type whose full view is a modular type.
15415 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
15416 Address_Clause, use the associated Expression as the GNAT tree
15417 representing the choice value to ensure the corresponding GCC tree is
15418 of the proper kind.
15419 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
15420 instead of just the operands, as the base GCC stabilize_reference does.
15421 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
15422 requested; otherwise fail.
15423 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

15428 implementation of UI_Div.
15429 (UI_Div): Reimplement as a call to UI_Div_Rem.
15430 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
15431 remainder, avoiding the cost of a multiplication and a subtraction.
15432 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
15433 provides both quotient and remainder in a single computation.
15434 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
15435 functions for uint.
15436 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
15437 is undefined if the given n is not inversible.
15439 2007-04-06 Olivier Hainque <hainque@adacore.com>

15446 Olivier Hainque <hainque@adacore.com>
15448 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
15449 when updating the contents of the old pointer to an unconstrained array.
15450 (end_subprog_body): Set error_gnat_node to Empty.
15451 (write_record_type_debug_info): Do not be unduly sparing with our bytes.

15557 untagged derived type, add hidden components to keep discriminant
15558 layout consistent, when a given discriminant of the derived type

15683 (mainly static expression evaluation).
15684 Reword some continuation messages
15685 Add some \\ sequences to continuation messages
15686 (Resolve_Call): Refine infinite recursion case. The test has been

15700 during analysis, and use May_Be_Lvalue to distinguish read/write.
15701 (Valid_Array_Conversion): New procedure, abstracted from
15702 Valid_Conversion, to incorporate accessibility checks for arrays of
15703 anonymous access types.
15704 (Valid_Conversion): For a conversion to a numeric type occurring in an
15705 instance or inlined body, no need to check that the operand type is
15706 numeric, since this has been checked during analysis of the template.

15989 alignment of a field in a variant record might not be accurate. Add a
15990 safety test to make sure no alignment is set to a smaller value than
15991 the alignment of the field type.

16460 subcomponent's enclosing variable is aliased with a constrained subtype.
16461 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
16462 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
16463 an aliased prefix must be known to be constrained in order to use True
16464 for the attribute value, and now it's possible for some aliased views
16465 to be unconstrained.
16467 2006-10-31 Robert Dewar <dewar@adacore.com>
16469 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
16470 (Expand_Entity_Reference): Correct error of not handling subprogram
16471 formals in current_value processing.
16473 2006-10-31 Javier Miranda <miranda@adacore.com>
16474 Robert Dewar <dewar@adacore.com>
16475 Ed Schonberg <schonberg@adacore.com>
16476 Gary Dismukes <dismukes@adacore.com>
16478 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
16479 register in the final list objects containing class-wide interfaces;
16480 otherwise we incorrectly register the tag of the interface in the final
16482 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
16483 generate the wrapper if the parent primitive is abstract. This is
16484 required to report the correct error message.
16485 (Expand_N_Subtype_Indication): Do validity checks on range
16486 (Clean_Task_Names): If an initialization procedure includes a call to
16487 initialize a task (sub)component, indicate that the procedure will use
16488 the secondary stack.
16489 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
16490 compatibility for interfacing with CPP by default.
16491 (Expand_N_Object_Declaration): Only build an Adjust call when the
16492 object's type is a nonlimited controlled type.
16493 * exp_ch3.adb: Add with and use of Exp_Ch6.
16494 (Expand_N_Object_Declaration): Check for object initialization that is a
16495 call to build-in-place function and apply Make_Build_In_Place_Call_In_
16496 Object_Declaration to the call.
16497 (Freeze_Type): When the designated type of an RACW was not frozen at the
16498 point where the RACW was declared, validate the primitive operations
16499 with respect to E.2.2(14) when it finally is frozen.
16500 (Build_Initialization_Call,Expand_Record_Controller): Rename
16501 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
16502 return-by-reference has no meaning in Ada 2005.
16503 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
16504 to register tag of the immediate ancestor interfaces in the
16505 run-time structure.
16506 (Init_Secondary_Tags): Moved to the specification to allow the
16507 initialization of extension aggregates with abstract interfaces.
16508 (Build_Master_Renaming): Make public, for use by function declarations
16509 whose return type is an anonymous access type.
16510 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
16511 Insert_List_Before_And_Analyze after the generation of the specs
16512 associated with null procedures.
16513 (Expand_Tagged_Root): Update documentation in its specification.
16514 (Init_Secondary_Tags): Update documentation.
16515 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
16516 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
16517 then generate code to inherit the contents of the dispatch table
16518 directly from the ancestor.
16519 (Expand_Record_Controller): Insert controller component after tags of
16520 implemented interfaces.
16521 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
16522 create null procedure overridings when null procedures are inherited
16524 (Make_Null_Procedure_Specs): New procedure to generate null procedure
16525 declarations for overriding null primitives inherited from interfaces.
16526 (Is_Null_Interface_Procedure): New function in
16527 Make_Null_Procedure_Specs.
16528 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
16529 immediate ancestor of a tagged type is an abstract interface type we
16530 must generate the specification of the predefined primitives associated
16531 with controlled types (because the dispatch table of the ancestor is
16532 null and hence these entries cannot be inherited). This is required to
16533 elaborate well the dispatch table.

16539 Robert Dewar <dewar@adacore.com>
16541 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
16543 (Expand_N_In): Do validity checks on range
16544 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
16545 (Expand_N_Allocator): For "new T", if the object is constrained by
16546 discriminant defaults, allocate the right amount of memory, rather than
16547 the maximum for type T.
16548 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
16549 when the allocator is initialized by a build-in-place call, since the
16550 allocator is already rewritten as a reference to the function result,
16551 and this prevents an unwanted duplication of the function call.
16552 Add with and use of Exp_Ch6.
16553 (Expand_Allocator_Expresssion): Check for an allocator whose expression
16554 is a call to build-in-place function and apply
16555 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
16556 untagged designated types).
16557 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
16558 optimization if source or target is biased.
16559 (Expand_N_Allocator): Add comments for case of an allocator within a
16560 function that returns an anonymous access type designating tasks.
16561 (Expand_N_Allocator): apply discriminant checks for access
16562 discriminants of anonymous access types (AI-402, AI-416)
16564 2006-10-31 Bob Duff <duff@adacore.com>
16565 Robert Dewar <dewar@adacore.com>
16566 Gary Dismukes <dismukes@adacore.com>
16567 Ed Schonberg <schonberg@adacore.com>
16569 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
16571 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
16572 (Expand_N_Assignment_Statement): Call
16573 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
16574 build-in-place function call. Currently, this can happen only for
16575 assignments that come from aggregates.
16576 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
16577 in order to alleviate the upward compatibility introduced by AI-318.
16578 (Expand_N_Extended_Return_Statement): Add support for handling the
16579 return object as a build-in-place result.
16580 (Expand_Non_Function_Return): Implement simple return statements nested
16581 within an extended return.
16582 (Enable_New_Return_Processing): Turn on the new processing of return
16584 (Expand_Non_Function_Return): For a return within an extended return,
16585 don't raise Program_Error, because Sem_Ch6 now gives a warning.
16586 (Expand_N_Extended_Return_Statement): Implement AI-318
16587 (Expand_Simple_Function_Return): Ditto.
16588 (Expand_N_If_Statement): Handle new -gnatwt warning
16589 (Expand_N_Case_Statement): Handle new -gnatwt warning
16590 (Expand_N_Assignment): Handle assignment to the Priority attribute of
16591 a protected object.
16592 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
16593 validity checking of assignments to elementary record components.
16594 (Expand_N_Return_Statement): return Class Wide types on the secondary
16595 stack independantly of their controlled status since with HIE runtimes,
16596 class wide types are not potentially controlled anymore.
16598 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
16601 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
16602 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
16603 it expects a block, procedure, or task. The return statement will get
16604 turned into a block, and Expand_Cleanup_Actions will happen then.
16606 2006-10-31 Robert Dewar <dewar@adacore.com>
16607 Ed Schonberg <schonberg@adacore.com>
16608 Bob Duff <duff@adacore.com>
16609 Gary Dismukes <dismukes@adacore.com>
16611 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
16613 (Expand_Inlined_Call): Tagged types are by-reference types, and
16614 therefore should be replaced by a renaming declaration in the expanded
16615 body, as is done for limited types.
16616 (Expand_Call): If this is a call to a function with dispatching access
16617 result, propagate tag from context.
16618 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
16620 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
16621 build-in-place when the right-hand side of an assignment is a
16622 build-in-place function call.
16623 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
16624 of the explicit dereference of the allocator to the result subtype of
16625 the build-in-place function. This is needed to satisfy type checking
16626 in cases where the caller's return object is created by an allocator for
16627 a class-wide access type and the type named in the allocator is a
16629 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
16630 conversion of the reference to the declared object to the result subtype
16631 of the build-in-place function. This is needed to satisfy type checking
16632 in cases where the declared object has a class-wide type. Also, in the
16633 class-wide case, change the type of the object entity to the specific
16634 result subtype of the function, to avoid passing a class-wide object
16635 without explicit initialization to the back end.
16636 (Register_Interface_DT_Entry): Moved outside the body of
16637 Freeze_Subprogram because this routine is now public; it is called from
16638 Check_Dispatching_Overriding to handle late overriding of abstract
16639 interface primitives.
16640 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
16641 adding an implicit access actual on a call to a build-in-place function.
16642 (Expand_Actuals): Test for an actual parameter that is a call to a
16643 build-in-place function and apply
16644 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
16645 (Is_Build_In_Place_Function): New function to determine whether an
16646 entity is a function whose calls should be handled as build-in-place.
16647 (Is_Build_In_Place_Function_Call): New function to determine whether an
16648 expression is a function call that should handled as build-in-place.
16649 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
16650 calls to build-in-place functions as the initialization of an allocator.
16651 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
16652 handling calls to build-in-place functions in contexts that do not
16653 involve init of a separate object (for example, actuals of subprogram
16655 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
16656 handling calls to build-in-place functions as the initialization of an
16657 object declaration.
16658 (Detect_Infinite_Recursion): Add explicit parameter Process to
16659 instantiation of Traverse_Body to avoid unreferenced warning.
16660 (Check_Overriding_Inherited_Interfaces): Removed.
16661 (Register_Interface_DT_Entry): Code cleanup.
16662 (Register_Predefined_DT_Entry): Code cleanup.
16663 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
16664 inlined statements if within a transient scope.
16665 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
16666 formal parameters with occurrences of actuals in inlined body, establish
16667 visibility on the proper view of the actual's subtype for the body's
16669 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
16670 compatibility mode and we have an imported CPP subprogram because
16671 for now we assume that imported CPP primitives correspond with
16672 objects whose constructor is in the CPP side (and therefore we
16673 don't need to generate code to register them in the dispatch table).
16674 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
16675 aligned selected component.
16676 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
16677 the actual of an in-mode parameter is a type conversion.
16678 (Expand_Actuals): If the call does not come from source and the actual
16679 is potentially misaligned, let gigi handle it rather than rejecting the
16680 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
16681 Class Wide types as returning by reference independantly of their
16682 controlled status since with HIE runtimes class wide types are not
16683 potentially controlled anymore.
16685 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16687 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
16688 references that are private components of the protected object.
16689 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
16690 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
16691 instantiation to deal with warnings.
16692 (Initialize_Protection): If expression for priority is non-static, use
16693 System_Priority as its expected type, in case the expression has not
16696 2006-10-31 Robert Dewar <dewar@adacore.com>
16698 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
16699 initialization of Homonym_Len.
16700 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
16701 names from fully qualified name. Fixes problem of duplicate
16702 external names differing only in the presence of such a block name.
16704 2006-10-31 Thomas Quinot <quinot@adacore.com>
16705 Pablo Oliveira <oliveira@adacore.com>
16707 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
16708 subprogram Ids, even if they are not yet assigned.
16709 (Build_Subprogram_Id): It is now this function that will take care of
16710 calling Assign_Subprogram_Ids if necessary.
16711 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
16712 should be done only once they are assigned.
16713 (Build_From_Any_Function, case of tagged types): Add missing call to
16715 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
16716 type for an RACW type.
16717 (Add_RACW_Features): When processing an RACW declaration for which the
16718 designated type is already frozen, enforce E.2.2(14) rules immediately.
16719 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
16720 special reordering of controlling formals.
16722 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
16723 associated stub type for an RACW type.
16725 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16727 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
16728 fixed-point operations in an integer context, i.e. as operands of a
16729 conversion to an integer type, indicate that result must be rounded.
16731 2006-10-31 Robert Dewar <dewar@adacore.com>
16733 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
16734 cases, pass the encoding method, since it is now required by the run
16737 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
16738 assumption that Str'First = 1.
16739 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
16740 it on to the Value_Wide_Wide_Character call.
16741 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
16742 properly handles a string of the form quote-encoded_wide_char-quote.
16744 * s-wchcnv.adb: Minor reformatting
16746 2006-10-31 Javier Miranda <miranda@adacore.com>
16748 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
16749 run-time membership test to ensure that the constructed object
16750 implements the target abstract interface.
16752 2006-10-31 Robert Dewar <dewar@adacore.com>
16754 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
16755 Machine_Attribute pragma internally to implement the user pragma.
16756 Add processing for pragma Interface so that it is now completely
16757 equivalent to pragma Import.
16759 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
16760 so that it can be applied to all entities, including record components
16761 and enumeration literals.
16762 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
16763 priority ranges are correct, verify compatibility against task
16764 dispatching and locking policies, and if everything is correct an entry
16765 is added to the table containing priority specific dispatching entries
16766 for this compilation unit.
16767 (Delay_Config_Pragma_Analyze): Delay processing
16768 Priority_Specific_Dispatching pragmas because when processing the
16769 pragma we need to access run-time data, such as the range of
16770 System.Any_Priority.
16771 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
16772 Allow pragma Unreferenced as a context item
16773 Add pragma Preelaborable_Initialization
16774 (Analyze_Pragma, case Interface): Interface is extended so that it is
16775 now syntactically and semantically equivalent to Import.
16776 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
16777 insertion characters.
16778 Add handling for Pragma_Wide_Character_Encoding
16779 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
16780 never supercedes a real restriction, and that a real restriction
16781 always supercedes a warning.
16782 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

16790 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
16791 Is_Inherently_Limited_Type, because return-by-reference has no meaning
16793 (Find_Node_To_Be_Wrapped): Use new method of determining the result
16794 type of the function containing a return statement, because the
16795 Return_Type field was removed. We now use the Return_Applies_To field.
16797 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
16798 (Build_Task_Image_Decl): If procedure is not called from an
16799 initialization procedure, indicate that function that builds task name
16800 uses the sec. stack. Otherwise the enclosing initialization procedure
16801 will carry the indication.
16802 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
16803 N_Object_Declaration instead.
16804 (Kill_Dead_Code): New interface to implement -gnatwt warning for
16805 conditional dead code killed, and change implementation accordingly.
16806 (Insert_Actions): Add N_Return_Object_Declaration case.
16807 Correct comment to mention N_Extension_Aggregate node.
16808 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
16809 attempts to save information for global variables which cannot be
16811 (Get_Current_Value_Condition): Handle conditions the other way round
16812 (constant on left). Also handle right operand of AND and AND THEN

16814 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
16815 (Get_Current_Value_Condition): Handle simple boolean operands
16816 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
16817 (Get_Current_Value_Condition): If the variable reference is within an
16818 if-statement, does not appear in the list of then_statments, and does
16819 not come from source, treat it as being at unknown location.
16820 (Get_Current_Value_Condition): Enhance to allow while statements to be
16821 processed as well as if statements.
16822 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
16824 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
16825 of loop. This is safe now that we fixed Kill_Current_Values.
16826 (OK_To_Do_Constant_Replacement): Check whether current scope is
16827 Standard, before examining outer scopes.
16829 2006-10-31 Vincent Celier <celier@adacore.com>
16831 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
16832 When True, apply VMS treatment to children of packages A, G, I and S.
16835 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
16837 2006-10-31 Robert Dewar <dewar@adacore.com>

16850 (Generate_Reference): Accept an implicit reference generated for a
16851 default in an instance.
16852 (Generate_Reference): Accept a reference for a node that is not in the
16853 main unit, if it is the generic body corresponding to an subprogram
16856 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
16858 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
16860 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
16862 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
16863 use clauses, to avoid messages on packages used to qualify, and also
16864 to avoid messages from obsolescent units.
16865 (Warn_On_Useless_Assignments): Don't generate messages for imported
16866 and exported variables.
16867 (Warn_On_Useless_Assignments): New procedure
16868 (Output_Obsolescent_Entity_Warnings): New procedure
16869 (Check_Code_Statement): New procedure
16871 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
16872 Change name Is_Ada_2005 to Is_Ada_2005_Only
16873 (Last_Assignment): New field for useless assignment warning
16875 2006-10-31 Olivier Hainque <hainque@adacore.com>
16877 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
16878 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
16880 2006-10-31 Bob Duff <duff@adacore.com>
16881 Robert Dewar <dewar@adacore.com>
16882 Ed Schonberg <schonberg@adacore.com>
16884 * g-awk.adb (Default_Session, Current_Session): Compile this file in
16885 Ada 95 mode, because it violates the new rules for AI-318.
16887 * g-awk.ads: Use overloaded subprograms in every case where we used to
16888 have a default of Current_Session. This makes the code closer to be
16889 correct for both Ada 95 and 2005.
16891 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
16892 code, relying on the fact that the compiler generates a warning
16893 instead of an error in -gnatg mode.
16895 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
16896 E_Return_Statement entity kind.
16897 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
16899 * par.adb (P_Interface_Type_Definition): Addition of one formal to
16900 report an error if the reserved word abstract has been previously found.
16901 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
16903 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
16904 parenthesized range attribute usage
16905 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
16907 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
16908 in the syntax for extended_return_statement. This is not in the latest
16909 RM, but the ARG is expected to issue an AI allowing this.
16910 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
16911 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
16912 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
16913 P_Return_Statement): Parse the new syntax for extended_return_statement.
16915 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
16916 Output_End_Missing): Add error-recovery code for the new
16917 extended_return_statement syntax; that is, the new E_Return entry on
16920 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
16921 limited to nonlimited, because otherwise we violate the new Ada 2005
16922 rules about returning limited types in function Create_AST_Handler in
16925 * sem.adb (Analyze): Add cases for new node kinds
16926 N_Extended_Return_Statement and N_Return_Object_Declaration.
16928 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
16929 type is in the same category as type of context before applying check,
16930 to prevent anomalies in instantiations.
16931 (Resolve_Aggregate): Remove test for limited components in aggregates.
16932 It's unnecessary in Ada 95, because if it has limited components, then
16933 it must be limited. It's wrong in Ada 2005, because limited aggregates
16935 (Resolve_Record_Aggregate): Move check for limited types later, because
16936 OK_For_Limited_Init requires its argument to have been resolved.
16937 (Get_Value): When copying the component default expression for a
16938 defaulted association in an aggregate, use the sloc of the aggregate
16939 and not that of the original expression, to prevent spurious
16940 elaboration errors, when the expression includes function calls.
16941 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
16942 were missing. We also didn't handle qualified expressions. Now also
16943 allow function calls. Use new common routine OK_For_Limited_Init.
16944 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
16945 with space can upper case letter).
16947 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
16948 Has_Static_Discriminants flag
16949 (Record_Type_Declaration): Diagnose an attempt to declare an interface
16950 type with discriminants.

16952 (Build_Discriminant_Constraints): Use updated form of
16953 Denotes_Discriminant.
16954 (Process_Subtype): If the subtype is a private subtype whose full view
16955 is a concurrent subtype, introduce an itype reference to prevent scope
16957 (Build_Derived_Record_Type, Collect_Interface_Primitives,
16958 Record_Type_Declaration): The functionality of the subprograms
16959 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
16960 is now performed by a single routine.
16961 (Build_Derived_Record_Type): If the type definition includes an explicit
16962 indication of limitedness, then the type must be marked as limited here
16963 to ensure that any access discriminants will not be treated as having
16964 a local anonymous access type.
16965 (Check_Abstract_Overriding): Issue a detailed error message when an
16966 abstract subprogram was not overridden due to incorrect mode of its
16968 (Analyze_Private_Extension_Declaration): Add support for the analysis of
16969 synchronized private extension declarations. Verify that the ancestor is
16970 a limited or synchronized interface or in the generic case, the ancestor
16971 is a tagged limited type or synchronized interface and all progenitors
16972 are either limited or synchronized interfaces.
16973 Derived_Type_Declaration): Check for presence of private extension when
16974 dealing with synchronized formal derived types.
16975 Process_Full_View): Enchance the check done on the usage of "limited" by
16976 testing whether the private view is synchronized.
16977 Verify that a synchronized private view is completed by a protected or
16979 (OK_For_Limited_Init_In_05): New function.
16980 (Analyze_Object_Declaration): Move check for limited types later,
16981 because OK_For_Limited_Init requires its argument to have been resolved.
16982 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
16983 in order to alleviate the upward compatibility introduced by AI-318.
16984 (Constrain_Corresponding_Record): If the constraint is for a component
16985 subtype, mark the itype as frozen, to avoid out-of-scope references to
16986 discriminants in the back-end.
16987 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
16988 this subprogram against wrong sources.
16989 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
16990 discriminant of limited type completed with a protected type, when the
16991 discriminant is used to constrain a private component of the type, and
16992 expansion is disabled.
16993 (Find_Type_Of_Object): Do not treat a return subtype that is an
16994 anonymous subtype as a local_anonymous_type, because its accessibility
16995 level is the return type of the enclosing function.
16996 (Check_Initialization): In -gnatg mode, turn the error "cannot
16997 initialize entities of limited type" into a warning.
16998 (OK_For_Limited_Init): Return true for generated nodes, since it
16999 sometimes violates the legality rules.
17000 (Make_Incomplete_Declaration): If the type for which an incomplete
17001 declaration is created happens to be the currently visible entity,
17002 preserve the homonym chain when removing it from visibility.
17003 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17004 inherited subprograms.
17005 (Access_Definition): If this is an access to function that is the return
17006 type of an access_to_function definition, context is a type declaration
17007 and the scope of the anonymous type is the current one.
17008 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17009 incomplete subtype to the set of private dependents of the original
17011 (Constrain_Discriminated_Type): Emit an error message whenever an
17012 incomplete subtype is being constrained.
17013 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17014 corresponding subtype of the full view of the original incomplete type.
17015 (Check_Incomplete): Properly detect invalid usage of incomplete types

17029 Robert Dewar <dewar@adacore.com>
17031 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
17032 handling executable extension manually and duplicating code.
17034 * make.adb: Implement new -S switch
17035 (Gnatmake): Use new function Osint.Executable_Name instead
17036 of handling executable extension manually.
17038 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
17039 is specified, the executable name ends with this suffix.
17040 Take advantage of Osint.Executable_Name instead of duplicating code.
17042 * switch-m.adb: Recognize new gnatmake -S switch
17044 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
17046 (Get_Target_Parameters): Set Executable_Extension_On_Target if
17049 * makeusg.adb: Add line for gnatmake -S switch
17051 2006-10-31 Vincent Celier <celier@adacore.com>
17053 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17054 call it with -static-libgcc, as there are some platforms, such as
17055 Darwin, where one of these two switches is compulsory to link.
17057 2006-10-31 Vincent Celier <celier@adacore.com>
17059 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17060 instead of ADA_PROJECT_PATH, for the project path.
17061 (Gnatls): When displaying the project path directories, use host dir
17064 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17065 names in the project path, as absolute paths may correspond to
17066 multi-valued VMS logical names.
17068 2006-10-31 Vincent Celier <celier@adacore.com>
17070 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
17071 absolute path name.
17072 (Locate_Regular_File): Ditto
17073 (Change_Dir): Remove, no longer used
17074 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
17075 on Windows. Get it calling Get_Current_Dir.

17077 (Normalize_Pathname)[VMS]: Do not resolve directory names.
17078 (Pid_To_Integer): New function to convert a Process_Id to Integer
17080 2006-10-31 Thomas Quinot <quinot@adacore.com>

17083 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
17085 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
17088 2006-10-31 Robert Dewar <dewar@adacore.com>

17097 2006-10-31 Robert Dewar <dewar@adacore.com>
17099 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
17101 (Layout_Variant_Record): Retrieve the discriminants from the entity
17102 rather than from the type definition, because in the case of a full
17103 type for a private type we need to take the discriminants from the
17105 (Layout_Component_List): When applying the Max operator to variants with
17106 a nonstatic size, check whether either operand is static and scale that
17107 operand from bits to storage units before applying Max.
17108 (Layout_Type): In VMS, if a C-convention access type has no explicit
17109 size clause (and does not inherit one in the case of a derived type),
17110 then the size is reset to 32 from 64.
17112 2006-10-31 Vincent Celier <celier@adacore.com>
17114 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
17115 its file has already been loaded, according to the unit being loaded,
17116 not to the current value of Multiple_Unit_Index.
17118 2006-10-31 Thomas Quinot <quinot@adacore.com>
17119 Eric Botcazou <ebotcazou@adacore.com>

17151 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
17154 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17156 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
17157 Process_Body_Clauses): If the context of a body includes a use clause
17158 for P.Q then a with_clause for P in the same body is not redundant,
17159 even if the spec also has a with_clause on P.
17160 Add missing continuation mark to error msg
17161 (Build_Limited_Views): A limited view of a type is tagged if its
17162 declaration includes a record extension.
17163 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
17164 node, even if the subunit has errors. This avoids malfunction by
17165 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
17166 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
17167 generation of obsolescent messages for with statements (cannot do
17168 this too early, or we cannot implement avoiding the messages in the
17169 case of obsolescent units withing obsolescent units).
17170 (Install_Siblings): If the with_clause is on a remote descendant of
17171 an ancestor of the current compilation unit, find whether there is
17172 a sibling child unit that is immediately visible.
17173 (Remove_Private_With_Clauses): New procedure, invoked after completing
17174 the analysis of the private part of a nested package, to remove from
17175 visibility the private with_clauses of the enclosing package
17177 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
17178 now centralized in Generate_Reference.
17179 (Install_Limited_Context_Clauses): Remove superfluous error
17180 message associated with unlimited view visible through use
17181 and renamings. In addition, at the point in which the error
17182 is reported, we add the backslash to the text of the error
17183 to ensure that it is reported as a single error message.
17184 Use new // insertion for some continuation messages
17185 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
17186 to create implicit with_clause for parent unit mentioned in original
17187 limited_with_clause.
17188 (Install_Limited_With_Unit): Set entity of parent identifiers if the
17189 unit is a child unit. For ASIS queries.
17190 (Analyze_Subunit): If the subunit appears within a child unit, make all
17191 ancestor child units directly visible again.

17206 a formal object declaration with an access definition or a subtype mark
17207 with a null exclusion.
17208 (P_Generic_Association): Handle association with box, and others_choice
17209 with box, to support Ada 2005 partially parametrized formal packages.
17211 2006-10-31 Robert Dewar <dewar@adacore.com>
17212 Javier Miranda <miranda@adacore.com>
17214 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
17215 (P_Type_Declaration): Remove barrier against the reserved word "limited"
17216 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
17217 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
17218 private extensions.
17219 (P_Type_Declaration): Add the new actual Abstract_Present to every call
17220 to P_Interface_Type_Definition.
17221 (P_Interface_Type_Definition): Addition of one formal to report an error
17222 if the reserved word abstract has been previously found.
17223 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
17224 object renaming declaration with an access definition or subtype mark
17225 with a possible null exclusion.

17244 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
17247 2006-10-31 Vincent Celier <celier@adacore.com>
17249 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
17250 on VMS, change "__" to '.' before checking the name.
17251 (Record_Ada_Source): Always add the source file name in the list of
17252 of sources, even if it is not the first time, as it is for another
17254 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
17255 dot, instead of replacing only the first '_'.
17257 * prj-part.adb (Parse): Convert project file path to canonical form
17259 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
17260 extended, the project id of the project extending it is recorded in its
17261 data, even when it has already been processed as an imported project.
17263 2006-10-31 Robert Dewar <dewar@adacore.com>
17265 * repinfo.adb (List_Entities): Don't list entities from renaming

17269 Robert Dewar <dewar@adacore.com>
17271 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
17272 only a restriction warning is active for the given restriction. This is
17273 desirable because we do not want to modify code in the case where only
17275 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
17276 causes overriding of real restrictions.
17277 Take advantage of new No_Restrictions constant.
17279 * raise.h: (__gnat_set_globals): Change profile.
17281 2006-10-31 Arnaud Charlet <charlet@adacore.com>
17283 * rtsfind.adb: Remove s-polint from comment as it exists no more.

17308 (OK_Self_Reference): New subprogram to check the legality of an access
17309 attribute whose prefix is the type of an enclosing aggregate.
17310 Generalizes previous mechanism to handle attribute references nested
17311 arbitrarily deep within the aggregate.
17312 (Analyze_Access_Attribute): An access attribute whose prefix is a type
17313 can appear in an aggregate if this is a default-initialized aggregate
17314 for a self-referential type.
17315 (Resolve_Attribute, case Access): Ditto.
17316 Add support for new implementation defined attribute Stub_Type.
17317 (Eval_Attribute, case Attribute_Stub_Type): New case.
17318 (Analyze_Attribute, case Attribute_Stub_Type): New case.
17319 (Stream_Attribute_Available): Implement using new subprogram from
17320 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
17321 Has_Specified_Stream_Attribute flag.
17322 Disallow Storage_Size and Storage_Pool for access to subprogram
17323 (Resolve_Attribute, case 'Access et al): Take into account anonymous
17324 access types of return subtypes in extended return statements. Remove
17325 accessibility checks on anonymous access types when Unchecked_Access is
17327 (Analyze_Attribute): Add support for the use of 'Class to convert
17328 a class-wide interface to a tagged type.
17329 Add support for the attribute Priority.
17330 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
17331 whether the designated type is discriminated with a constrained partial
17332 view and require static matching in that case.
17333 Add local variable Des_Btyp. The Designated_Type
17334 of an access to incomplete subtype is either its non-limited view if
17335 coming from a limited with or its etype if regular incomplete subtype.
17337 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
17338 Fix predicate to identify and allow cases of (expander-generated)
17339 references to tag of designated object of a RACW.
17340 (Validate_Static_Object_Name): In Ada 2005, a formal object is
17341 non-static, and therefore cannot appear as a primary in a preelaborable
17343 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
17344 Has_Read_Write_Attributes.
17345 (Has_Read_Write_Attributes): Reimplement in termes of

17351 2006-10-31 Robert Dewar <dewar@adacore.com>
17353 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
17354 useless assignments here and conditionalize it on absence of exception
17356 (Analyze_Exception_Handlers): Small code reorganization of error
17357 detection code, for new handling of formal packages.
17359 2006-10-31 Ed Schonberg <schonberg@adacore.com>

17365 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
17366 generated private extension declaration if the formal derived type is
17367 synchronized. Carry synchronized present over to the generated private
17369 (Validate_Derived_Type_Instance): Ensure that the actual of a
17370 synchronized formal derived type is a synchronized tagged type.
17371 (Instantiate_Formal_Package): When creating the instantiation used to
17372 validate the actual package of a formal declared without a box, check
17373 whether the formal itself depends on a prior actual.
17374 (Instantiate_Formal_Subprogram): Create new entities for the defining
17375 identifiers of the formals in the renaming declaration, for ASIS use.
17376 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
17377 a renaming declaration or a subtype declaration for an actual in an
17378 instance, capture location information of declaration in generic, for
17380 (Instantiate_Formal_Package): Add comments on needed additional tests.
17381 AI-317 (partial parametrization) is fully implemented.
17382 (Validate_Private_Type_Instance): Add check for actual which
17383 must have preelaborable initialization
17384 Use new // insertion for some continuation messages
17385 (Analyze_Formal_Object_Declaration): Change usage of Expression to
17386 Default_Expression. Add type retrieval when the declaration has an
17387 access definition. Update premature usage of incomplete type check.
17388 (Check_Access_Definition): New subsidiary routine. Check whether the
17389 current compilation version is Ada 05 and the supplied node has an
17391 (Instantiate object): Alphabetize local variables. Handle the creation
17392 of new renaming declarations with respect to the kind of definition
17393 used - either an access definition or a subtype mark. Guard against
17394 unnecessary error message in the context of anonymous access types after
17395 they have been resolved. Add check for required null exclusion in a
17396 formal object declaration.
17397 (Switch_View): A private subtype of a non-private type needs to be
17398 switched (the base type can have been switched without its private
17399 dependents because of the last branch of Check_Private_View.
17400 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
17402 (Instantiate_Type): Emit an error message whenever a class-wide type of
17403 a tagged incomplete type is used as a generic actual.
17404 (Find_Actual_Type): Extend routine to handle a component type in a child
17405 unit that is imported from a formal package in a parent.
17406 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
17407 agree on constrainedness, rather than checking against ultimate ancestor
17408 (Instantiate_Subprogram_Body): Create a cross-reference link to the
17409 generic body, for navigation purposes.

17412 Thomas Quinot <quinot@adacore.com>
17414 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
17416 (New_Stream_Subprogram): When processing an attribute definition clause
17417 for a stream-oriented subprogram, record an entity node occurring at
17418 the point of clause to use for checking the visibility of the clause,
17419 as defined by 8.3(23) as amended by AI-195.
17420 (New_Stream_Subprogram): New procedure, factoring behaviour from both
17421 New_Stream_Function and New_Stream_Procedure.
17422 (New_Stream_Function, New_Stream_Procedure): Removed.
17423 (Analyze_Attribute_Definition_Clause, case Address): Check new
17424 Alignment_Check check

17427 Javier Miranda <miranda@adacore.com>
17428 Robert Dewar <dewar@adacore.com>
17430 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
17431 generate the same errors compiling under -gnatc.
17432 (Try_Object_Operation): If no candidate interpretation succeeds, but
17433 there is at least one primitive operation with the right name, report
17434 error in call rather than on a malformed selected component.
17435 (Analyze_Selected_Component): If the prefix is an incomplete type from
17436 a limited view, and the full view is available, use the full view to
17437 determine whether this is a prefixed call to a primitive operation.
17438 (Operator_Check): Verify that a candidate interpretation is a binary
17439 operation before checking the type of its second formal.
17440 (Analyze_Call): Add additional warnings for function call contexts not
17442 (Analyze_Allocator): Move the check for "initialization not allowed for
17443 limited types" after analyzing the expression. This is necessary,
17444 because OK_For_Limited_Init looks at the structure of the expression.
17445 Before analysis, we don't necessarily know what sort of expression it
17446 is. For example, we don't know whether F(X) is a function call or an
17447 indexed component; the former is legal in Ada 2005; the latter is not.
17448 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
17449 were missing. We also didn't handle qualified expressions. Now also
17450 allow function calls. Use new common routine OK_For_Limited_Init.
17451 (Analyze_Type_Conversion): Do not perform some legality checks in an
17452 instance, because the error message will be redundant or spurious.
17453 (Analyze_Overloaded_Selected_Component): Do not do style check when
17454 setting an entity, since we do not know it is the right entity yet.
17455 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
17456 (Analyze_Overloaded_Selected_Component): Same change
17457 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
17458 since regular incomplete subtypes are transformed into corresponding
17459 subtypes of their full views.
17460 (Complete_Object_Operation): Treat name of transformed subprogram call
17461 as coming from source, for browsing purposes.
17462 (Try_Primitive_Operation): If formal is an access parameter, compare
17463 with base type of object to determine whether it is a primitive
17465 (Operator_Check): If no interpretation of the operator matches, check
17466 whether a use clause on any candidate might make the operation legal.
17467 (Try_Class_Wide_Operation): Check whether the first parameter is an
17468 access type whose designated type is class-wide.

17475 warn on infinite loops.
17476 Add \\ to some continuation messages
17477 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
17478 (Process_Bounds): If the bounds are integer literals that result from
17479 constant-folding, and they carry a user-defined type, preserve that type
17480 rather than treating this as an integer range.
17481 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
17482 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
17483 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
17484 left hand side of assignment.
17485 (Analyze_Assignment): Add suport to manage assigments to the attribute
17486 priority of a protected object.
17487 (Check_Possible_Current_Value_Condition): Allow fully qualified names
17488 not just identifiers.
17489 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
17490 or AND THEN for possible tracking.
17491 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
17492 case of while loops so we can track values in the loop body.

17495 Hristian Kirtchev <kirtchev@adacore.com>
17496 Bob Duff <duff@adacore.com>
17498 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
17499 procedure cannot be a protected operation (it is a basic_declaration,
17500 not a subprogram_declaration).
17501 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
17502 Subp. Add logic for entry processing.
17503 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
17504 Determine whether an entry or subprogram of a protected or task type
17505 override an inherited primitive of an implemented interface.
17506 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
17507 Update the actual used in calls to Check_Overriding_Indicator.
17508 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
17509 generate the proper reference to the parent unit, for cross-reference.
17510 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
17512 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17513 (Add_Extra_Formal): Revise procedure to allow passing in associated
17514 entity, scope, and name suffix, and handle setting of the new
17515 Extra_Formals field.
17516 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
17517 pass new parameters. Add support for adding the new extra access formal
17518 for functions whose calls are treated as build-in-place.
17519 (Analyze_A_Return_Statement): Correct casing in error message.
17520 Move Pop_Scope to after Analyze_Function_Return, because an extended
17521 return statement really is a full-fledged scope. Otherwise, visibility
17522 doesn't work right. Correct use of "\" for continuation messages.
17523 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
17524 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
17525 the node doesn't get properly marked as analyzed.
17526 (Analyze_Subprogram_Body): If subprogram is a function that returns
17527 an anonymous access type that denotes a task, build a Master Entity
17529 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
17530 proper usage of null exclusion in a result definition.
17531 (Process_Formals): Code cleanup and new error message.
17532 (Process_Formals): Detect incorrect application of null exclusion to
17534 (Conforming_Types): Handle conformance between [sub]types and itypes
17535 generated for entities that have null exclusions applied to them.
17536 (Maybe_Primitive_Operation): Add an additional type retrieval when the
17537 base type is an access subtype. This case arrises with null exclusions.
17538 (New_Overloaded_Entity): Do not remove the overriden entity from the
17539 homonym chain if it corresponds with an abstract interface primitive.
17540 (Process_Formals): Replace membership test agains Incomplete_Kind with a
17541 call to the synthesized predicate Is_Incomplete_Type.
17542 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
17544 (Analyze_Subprogram_Declaration): Check that abstract interface
17545 primitives are abstract or null.
17546 (Analyze_Subprogram_Specification): Remove previous check for abstract
17547 interfaces because it was not complete.
17548 (Has_Interface_Formals): Removed.

17551 Javier Miranda <miranda@adacore.com>
17553 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
17554 of Analyze_Package_Body, to create Itype references for anonymous
17555 access types created in the package declaration, whose designated types
17556 may have only a limited view.
17557 (Analyze_Package_Specification): For the private part of a nested
17558 package, install private_with_clauses of enclosing compilation unit if
17559 we are in its visible part.
17560 (Declare_Inherited_Private_Subprograms): Complete barrier
17561 to ensure that the primitive operation has an alias to some parent
17562 primitive. This is now required because, after the changes done for the
17563 implementation of abstract interfaces, the contents of the list of
17564 primitives has entities whose alias attribute references entities of
17565 such list of primitives.
17566 (Analyze_Package_Specification): Simplify code that handles parent units
17567 of instances and formal packages.
17568 (Uninstall_Declarations): Check the convention consistency among
17569 primitive overriding operations of a tagged record type.

17573 Javier Miranda <miranda@adacore.com>
17574 Ed Schonberg <schonberg@adacore.com>
17576 * sem_ch8.adb: Minor error msg rewording
17577 (Undefined): When checking for misspellings, invert arguments (to get
17578 expected and found set right)
17579 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
17580 (Analyze_Generic_Renaming): Same fix
17581 (Use_One_Package): Do not take into account the internal entities of
17582 abstract interfaces during the analysis of entities that are marked
17583 as potentially use-visible.
17584 (Find_Type): Handle the case of an attribute reference for
17585 implementation defined attribute Stub_Type (simply let the analysis of
17586 the attribute reference rewrite it).
17587 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
17588 type that appears in a Use_Type clause.
17589 (Analyze_Object_Renaming): Add support for renaming of the Priority
17591 (Find_Type): In Ada 2005, a task type can be used within its own body,
17592 when it appears in an access definition.
17593 (Analyze_Object_Renaming): Remove warning on null_exclusion.
17594 (Analyze_Object_Renaming): Introduce checks for required null exclusion
17595 in a formal object declaration or in a subtype declaration.
17596 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
17597 (Check_Null_Exclusion): New local routine to
17598 Analyze_Subprogram_Renaming. Check whether the formals and return
17599 profile of a renamed subprogram have required null exclusions when
17600 their counterparts of the renaming already impose them.
17601 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
17602 Determine whether an entity is inside a generic scope.
17603 (In_Open_Scope): First pass of documentation update.
17604 (Find_Expanded_Name): Add support for shadow entities associated with
17605 limited withed packages. This is required to handle nested packages.
17606 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
17607 that makes a renaming of a limited withed package illegal.

17612 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
17613 Check_Overriding_Indicator.
17614 (Analyze_Task_Definition): Ditto.
17615 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
17616 (Check_Overriding_Indicator): To find overridden interface operation,
17617 examine only homonyms that have an explicit subprogram declaration, not
17618 inherited operations created by an unrelated type derivation.
17619 (Check_Overriding_Indicator): When checking for the presence of "null"
17620 in a procedure, ensure that the queried node is a procedure
17622 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
17623 type when the formal is an access to variable.
17624 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
17625 (Analyze_Task_Type): Same addition
17626 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to

17634 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
17635 inherited from an interface ancestor by another interface in the
17636 context of an instance as 'late'.
17637 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
17638 of a call to a function that dispatches on access result.
17639 (Check_Dispatching_Operation): In case of late overriding of a primitive
17640 that covers abstract interface subprograms we register it in all the
17641 secondary dispatch tables associated with abstract interfaces.
17642 (Check_Dispatching_Call): Add check that a dispatching call is not made
17643 to a function with a controlling result of a limited type. This is a
17644 current implementation restriction.
17645 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
17646 (Check_Dispatching_Operation): Do no emit a warning if the controlling
17647 argument is an interface type that is a generic formal.
17648 (Is_Interface_Subprogram): Removed.
17649 (Check_Dispatching_Operation): If the subprogram is not a dispatching
17650 operation, check the formals to handle the case in which it is
17651 associated with an abstract interface type.

17668 Hristian Kirtchev <kirtchev@adacore.com>
17669 Javier Miranda <miranda@adacore.com>
17671 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
17672 subprogram type to provide better diagnostics in case of ambiguity.
17673 (Covers): Handle coverage of formal and actual anonymous access types in
17674 the context of generic instantiation.
17675 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
17676 abstract interface types; this is required to handle concurrent types
17677 with discriminants and abstract interface types.
17678 (Covers): Include type coverage of both regular incomplete subtypes and
17679 incomplete subtypes of incomplete type visibles through a limited with

17691 Add missing continuation marks in error msgs
17692 (Unqualify): New function for removing zero or more levels of
17693 qualification from an expression. There are numerous places where this
17694 ought to be used, but we currently only deal properly with zero or one
17696 (In_Instance); The analysis of the actuals in the instantiation of a
17697 child unit is not within an instantiation, even though the parent
17698 instance is on the scope stack.
17699 (Safe_To_Capture_Value): Exclude the case of variables that are
17701 (Check_Obsolescent): Removed
17702 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
17703 is an aliased view, even when rewritten as a reference to the target
17704 object in an assignment.
17705 (Get_Subprogram_Entity): New function
17706 (Known_To_Be_Assigned): New function
17707 (Type_Access_Level): Compute properly the access level of a return

17714 has a null exclusion depending on its Nkind.
17715 Change Is_Lvalue to May_Be_Lvalue
17716 (May_Be_Lvalue): Extensive additional code to deal with subprogram
17717 arguments (IN parameters are not Lvalues, IN OUT parameters are).
17718 (Safe_To_Capture_Value): Extend functionality so it can be used for
17719 the current value condition case.
17720 (Has_Compatible_Alignment): New function
17721 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
17722 objects to handle the Ada 2005 case, where aliasedness no longer implies
17723 that the object is constrained. In particular, for dereferenced names,
17724 the designated object must be assumed to be unconstrained.
17725 (Kill_Current_Values): Properly deal with the case where we encounter
17726 a loop in the scope chain.
17727 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
17729 (Compile_Time_Constraint_Error): Improve error message in error case

17737 * s-osinte-tru64.adb:
17738 Mark Asm statements Volatile to prevent warnings (seems a
17739 reasonable change anyway)
17742 * s-mastop-irix.adb: Add Volatile to Asm statements
17743 Suppresses warning, and seems appropriate in any case
17745 * s-osinte-vms.adb: Add Volatile to Asm statement

17759 Private_Extension_Declaration to the list of assertions.
17760 (Is_Entry_Barrier_Function): New flag
17761 (Has_Self_Reference): New flag on aggregates, to indicate that they
17762 contain a reference to the enclosing type, inserted through a default
17764 (Next_Rep_Item): Move from Node4 to Node5.
17765 (Entity): Add this field for N_Attribute_Definition_Clause.
17766 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
17767 (N_Return_Object_Declaration): Remove this node kind. We now use
17768 N_Object_Declaration instead.
17769 (Actual_Designated_Subtype): Move to a different place to make room in
17770 N_Extended_Return_Statement.
17771 (Procedure_To_Call): Move to a different place to make room in
17772 N_Extended_Return_Statement.
17773 (Return_Type): Removed this field to make room in return statements
17775 (Return_Statement_Entity): New field in return statements, in part to
17776 replace Return_Type, and in part to support the fact that return
17777 statements are now pushed on the scope stack during semantic analysis.
17778 (Return_Object_Declarations): New field to support extended return
17780 (N_Extended_Return_Statement): New node for extended_return_statement
17782 (N_Return_Object_Declaration): New node for part of
17783 extended_return_statement nonterminal. Needed because all the necessary
17784 fields won't fit in N_Extended_Return_Statement.
17785 Generic_associations now carry the Box_Present flag, to indicate a
17786 default for an actual in a partially parametrized formal package.
17788 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
17789 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma
17790 and for the new predefined dispatching policies: EDF_Across_Priorities,

17792 Introduce new name Stub_Type for implementation defined attribute.
17793 Add pragma Preelaborable_Initialization

18384 Robert Dewar <dewar@adacore.com>
18386 * exp_ch4.adb (Expand_N_Allocator): If the allocated object is accessed
18387 through an access to class-wide interface we force the displacement of
18388 the pointer to the allocated object to reference the corresponding
18389 secondary dispatch table.
18390 (Expand_N_Op_Divide): Allow 64 bit divisions by small power of 2,
18391 if Long_Shifts are supported on the target, even if 64 bit divides
18392 are not supported (configurable run time mode).
18393 (Expand_N_Type_Conversion): Do validity check if validity checks on
18394 operands are enabled.
18395 (Expand_N_Qualified_Expression): Do validity check if validity checks
18396 on operands are enabled.

18407 the bounds of the type of the discriminant are not static expressions.
18409 * sem_aggr.adb (Check_Static_Discriminated_Subtype): Return false if
18410 the bounds of the discriminant type are not static.
18412 2006-02-17 Robert Dewar <dewar@adacore.com>
18414 * g-os_lib.adb (Copy_File): Make sure that if From has an Invalid_FD,
18415 then we close To if it is valid.
18417 2006-02-17 Vasiliy Fofanov <fofanov@adacore.com>
18419 * init.c (facility_resignal_table): new array
18420 (__gnat_default_resignal_p): enhance default predicate to resignal if
18421 VMS condition has one of the predefined facility codes.
18423 2006-02-17 Vasiliy Fofanov <fofanov@adacore.com>
18425 * Makefile.in: Use VMS64 specialized versions of several units in
18426 Interfaces.C hierarchy to be compatible with HP C default size choices.
18427 Use the default version of Ada.Synchronous_Task_Control for VxWorks 653.
18429 2006-02-17 Ed Schonberg <schonberg@adacore.com>
18431 * sem_ch10.adb (Analyze_With_Clause): If the unit is a subprogram
18432 instantiation, the corresponding entity is the related_instance of the
18433 wrapper package created for the instance.

18441 Ed Schonberg <schonberg@adacore.com>
18443 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
18444 type we cannot inherit the primitive operations; we inherit the
18445 Corresponding_Record_Type (which has the list of primitive operations).
18446 (Check_Anonymous_Access_Types): When creating anonymous access types for
18447 access components, use Rewrite in order to preserve the tree structure,
18449 (Analyze_Object_Declaration): For limited types with access
18450 discriminants with defaults initialized by an aggregate, obtain
18451 subtype from aggregate as for other mutable types.
18452 (Derived_Type_Declaration): If the derived type is a limited interface,
18453 set the corresponding flag (Is_Limited_Record is not sufficient).

18462 2006-02-17 Javier Miranda <miranda@adacore.com>
18464 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
18465 abstract interface type, the static analysis is not enough to know if
18466 the interface is implemented or not by the source tagged type. Hence
18467 we must pass the work to the expander to generate the required code to
18468 evaluate the conversion at run-time.
18469 (Resolve_Equality_Op): Do not apply previous
18470 transformation if expansion is disasbled, to prevent anomalies when
18471 locating global references in a generic unit.

18651 table to take advantage of the 16 priority levels available on Windows
18652 2000 and XP. On NT4 there are only 7 priority levels, this is properly
18653 supported by this new mapping.

18699 (Read): Change the implementation to support unicode characters. It is
18700 not possible to use strlen() on Windows as this version supports only
18701 standard ASCII characters. So the length of the directory entry is now
18702 returned from the imported __gnat_readdir routine.

18740 E_Floating_Point_Subtype>: Inherit alias set of what we are making a
18741 subtype of to ensure conflicts amongst all subtypes in a hierarchy,
18742 necessary since these are not different types and pointers may
18743 actually designate any subtype in this hierarchy.
18744 (gnat_to_gnu_entity, case E_Record_Type): Always make fields for
18745 discriminants but put them into record only if not Unchecked_Union;
18746 pass flag to components_to_record showing Unchecked_Union.
18747 (make_dummy_type): Use UNION_TYPE only if Unchecked_Union and no
18748 components before variants; don't set TYPE_UNCHECKED_UNION_P.

18750 Remove special case code for Unchecked_Union and instead use main code
18751 with small changes.
18754 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
18755 variable with the expression being built, only its inner field.

18758 emit_sequence_entry_statements.

18764 (Identifier_to_gnu): Manually unshare the DECL_INITIAL tree when it is
18765 substituted for a CONST_DECL.
18766 (tree_transform, case N_Aggregate): Remove code for UNION_TYPE and pass

19256 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
19257 procedure spec and body of the Offset_To_Top function that is generated
19258 when the parent of a type with discriminants has secondary dispatch
19260 (Init_Secondary_Tags): Handle the case in which the parent of the type
19261 containing secondary dispatch tables has discriminants to generate the
19262 correct arguments to call Set_Offset_To_Top.
19263 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
19265 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
19266 Add Wide_[Wide_]Expanded_Name.
19267 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
19268 the same functionality of Get_Prim_Op_Address but applied to predefined
19269 primitive operations because the pointers to the predefined primitives
19270 are now saved in a separate table.
19271 (Parent_Size): Modified to get access to the separate table of primitive
19272 operations or the parent type.
19273 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
19274 functionality of Set_Prim_Op_Address but applied to predefined primitive
19276 (Set_Signature): New subprogram used to store the signature of a DT.
19277 (Displace): If the Offset_To_Top value is not static then call the
19278 function generated by the expander to get such value; otherwise use
19279 the value stored in the table of interfaces.
19280 (Offset_To_Top): The type of the actual has been changed to Address to
19281 give the correct support to tagged types with discriminants. In this
19282 case this value is stored just immediately after the tag field.
19283 (Set_Offset_To_Top): Two new formals have been added to indicate if the
19284 offset_to_top value is static and hence pass this value to the run-time
19285 to store it in the table of interfaces, or else if this value is dynamic
19286 and then pass to the run-time the address of a function that is
19287 generated by the expander to provide this value for each object of the
19290 * rtsfind.ads (Default_Prin_Op_Count): Removed.
19291 (Default_Prim_Op_Count): New entity
19292 (Get_Predefined_Prim_Op_Address): New entity
19293 (Set_Predefined_Prim_Op_Address): New entity
19294 (RE_Set_Signature): New entity
19296 2006-02-13 Thomas Quinot <quinot@adacore.com>
19297 Ed Schonberg <schonberg@adacore.com>
19299 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
19300 Make_Adjust_Call done for a newly-allocated object.
19302 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
19303 in a subprogram are wrapped in a cleanup block, indicate that the
19304 subprogram contains an inner block with an exception handler.
19305 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
19306 Adjust call is for a newly-allocated object. In that case we must not
19307 assume that the finalization list chain pointers are correct (since they
19308 come from a bit-for-bit copy of the original object's pointers) so if
19309 the attach level would otherwise be zero (no change), we set it to 4
19310 instead to cause the pointers to be reset to null.
19312 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
19313 reset chain pointers to null.
19315 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19317 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
19318 string, and the context requires a loop for the assignment (e.g.
19319 because the left-hand side is packed), generate a unique name for the
19320 temporary that holds the string, to prevent spurious name clashes.
19322 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19323 Javier Miranda <miranda@adacore.com>
19324 Robert Dewar <dewar@adacore.com>
19325 Gary Dismukes <dismukes@adacore.com>
19327 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
19328 return unconstrained arrays.
19330 (Expand_Call): An indirect call through an access parameter of a
19331 protected operation is not a protected call.
19332 Add circuit to raise CE in Ada 2005 mode following call
19333 to Raise_Exception.
19334 (Register_DT_Entry): Do nothing if
19335 the run-time does not give support to abstract interfaces.
19336 (Freeze_Subprogram): In case of dispatching operations, do not generate
19337 code to register the operation in the dispatch table if the source
19338 is compiled with No_Dispatching_Calls.
19339 (Register_Predefined_DT_Entry): Generate code that calls the new
19340 run-time subprogram Set_Predefined_Prim_Op_Address instead of
19341 Set_Prim_Op_Address.
19343 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
19344 on array assignments if the right-hand side is a function call that has
19345 been inlined. Check is performed on the assignment in the block.
19346 (Process_Bounds): If bounds and range are overloaded, apply preference
19347 rule for root operations to disambiguate, and diagnose true ambiguity.
19348 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
19349 a tag-indeterminate right-hand side even when Expander_Active is True.
19350 Needed to ensure that dispatching calls to T'Input are allowed and
19351 get the tag of the target class-wide object.
19353 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
19354 an inherited primitive operation that already overrides several
19355 abstract interface primitives. For transitivity, the new entity must
19356 also override all the abstract interface primitives covered by the
19357 inherited overriden primitive.
19358 Emit warning if new entity differs from homograph in same scope only in
19359 that one has an access parameter and the other one has a parameter of
19360 a general access type with the same designated type, at the same
19361 position in the signature.
19362 (Make_Inequality_Operator): Use source locations of parameters and
19363 subtype marks from corresponding equality operator when creating the
19364 tree structure for the implicit declaration of "/=". This does not
19365 change anything in behaviour except that the decoration of the
19366 components of the subtree created for "/=" allows ASIS to get the
19367 string images of the corresponding identifiers.
19368 (Analyze_Return_Statement): Remove '!' in warning message.
19369 (Check_Statement_Sequence): Likewise.
19370 (Analyze_Subprogram_Body): For an access parameter whose designated type
19371 is an incomplete type imported through a limited_with clause, use the
19372 type of the corresponding formal in the body.
19373 (Check_Returns): Implicit return in No_Return procedure now raises
19374 Program_Error with a compile time warning, instead of beging illegal.
19375 (Has_Single_Return): Function returning unconstrained type cannot be
19376 inlined if expression in unique return statement is not an identifier.
19377 (Build_Body_To_Inline): It is possible to inline a function call that
19378 returns an unconstrained type if all return statements in the function
19379 return the same local variable. Subsidiary procedure Has_Single_Return
19380 verifies that the body conforms to this restriction.
19382 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
19383 same type, and one of them is of an anonymous access type, convert
19384 the other operand to it, so that this is a valid binary operation for
19386 (Resolve_Type_Conversion): Handle subtypes of protected types and
19387 task types when accessing to the corresponding record type.
19388 (Resolve_Allocator): Add '\' in 2-line warning message.
19389 Remove '!' in warning message.
19390 (Resolve_Call): Add '\' in 2-line warning message.
19391 (Valid_Conversion): Likewise.
19392 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
19393 resulting type may be an access type with an implicit dereference.
19394 Obtain the proper component from the designated type.
19395 (Make_Call_Into_Operator): Handle properly a call to predefined equality
19396 given by an expanded name with prefix Standard, when the operands are
19397 of an anonymous access type.
19398 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
19399 Explicit_Dereference and Resolve_Selected_Component, to verify that the
19400 prefix of the expression is not of an incomplete type. Allows full
19401 diagnoses of all semantic errors.
19402 (Resolve_Actuals): If the actual is an allocator whose directly
19403 designated type is a class-wide interface we build an anonymous
19404 access type to use it as the type of the allocator. Later, when
19405 the subprogram call is expanded, if the interface has a secondary
19406 dispatch table the expander will add a type conversion to force
19407 the displacement of the pointer.
19408 (Resolve_Call): If a function that returns an unconstrained type is
19409 marked Inlined_Always and inlined, the call will be inlined and does
19410 not require the creation of a transient scope.
19411 (Check_Direct_Boolean_Op): Removed
19412 (Resolve_Comparison_Op): Remove call to above
19413 (Resolve_Equality_Op): Remove call to above
19414 (Resolve_Logical_Op): Inline above, since this is only call.
19415 (Valid_Conversion): Handle properly conversions between arrays of
19416 convertible anonymous access types.
19419 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
19420 the literal in an unchecked conversion, because GCC 4.x needs a static
19421 value for a string bound.
19423 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19424 Hristian Kirtchev <kirtchev@adacore.com>
19426 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
19427 components of the corresponding record, take into account component
19428 definitions that are access definitions.
19429 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
19430 procedure is not considered a dispatching call and will be expanded
19433 2006-02-13 Javier Miranda <miranda@adacore.com>
19435 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
19436 controlling argument of the dispatching call is an abstract interface
19437 class-wide type then we use it directly.
19438 Check No_Dispatching_Calls restriction.
19439 (Default_Prim_Op_Position): Remove the code that looks for the last
19440 entity in the list of aliased subprograms. This code was wrong in
19442 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
19443 when the source is compiled with the No_Dispatching_Calls restriction.
19444 (Init_Predefined_Interface_Primitives): No need to inherit primitives
19445 if we are compiling with restriction No_Dispatching_Calls.
19446 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
19447 subprograms if we are compiling under No_Dispatching_Calls restriction.
19448 (Make_DT): Generate a dispatch table with a single dummy entry if
19449 we are compiling with the No_Dispatching_Calls restriction. In
19450 addition, in this case we don't generate code that calls to the
19451 following run-time subprograms: Set_Type_Kind, Inherit_DT.
19452 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
19453 of this subprogram if compiling with the No_Dispatching_Calls
19455 (Expand_Type_Conversion): Instead of using the actual parameter,
19456 the argument passed as parameter to the conversion function was
19457 erroneously referenced by the expander.
19458 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
19459 Set_Predefined_Primitive_Op_Address and Set_Signature.
19460 (Expand_Dispatching_Call): Generate call to
19461 Get_Predefined_Prim_Op_Address for predefined primitives.
19462 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
19463 predefined primitives.
19464 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
19465 primitives we reserve one dummy entry to ensure that the tag does not
19466 point to some memory that is associated with some other object. In
19467 addition, remove all the old code that generated the assignments
19468 associated with the signature of the dispatch table and replace them
19469 by a call to the new subprogram Set_Signature.
19470 (Set_All_DT_Position): Change the algorithm because now we have a
19471 separate dispatch table associated with predefined primitive operations.
19472 (Expand_Interface_Conversion): In case of non-static offset_to_top
19473 add explicit dereference to get access to the object after the call
19474 to displace the pointer to the object.
19475 (Expand_Interface_Thunk): Modify the generation of the actual used
19476 in the calls to the run-time function Offset_To_Top to fulfil its
19478 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
19480 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19482 * exp_dist.adb (Copy_Specification): For access parameters, copy
19483 Null_Exclusion flag, which will have been set for stream subprograms
19486 2006-02-13 Pascal Obry <obry@adacore.com>
19488 * expect.c (__gnat_expect_portable_execvp): New implementation. The
19489 previous implementation was using the C runtime spawnve routine but
19490 the corresponding wait was using directly the Win32 API. This was
19491 causing some times a lock when waiting for an event using
19492 WaitForSingleObject in __gnat_waitpid. This new implementation uses
19493 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
19494 API fixes this problem.
19496 2006-02-13 Robert Dewar <dewar@adacore.com>
19498 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

19506 array reference that is an explicit dereference, mark the converted
19507 (packed) array reference as analyzed to prevent a forthcoming
19508 reanalysis from resetting its type to the original (non-packed) array

19512 Javier Miranda <miranda@adacore.com>
19513 Eric Botcazou <ebotcazou@adacore.com>
19515 * exp_util.ads, exp_util.adb (Find_Prim_Op,
19516 Is_Predefined_Primitive_Operation): When
19517 searching for the predefined equality operator, verify that operands
19518 have the same type.
19519 (Is_Predefined_Dispatching_Operation): Remove the code that looks
19520 for the last entity in the list of aliased subprograms. This code
19521 was wrong in case of renamings.
19522 (Set_Renamed_Subprogram): New procedure
19523 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
19524 Exp_Type constant computed when entering this subprogram.

19526 (OK_To_Do_Constant_Replacement): New function
19527 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
19528 (Side_Effect_Free): An attribute reference 'Input is not free of
19529 side effect, unlike other attributes that are functions. (from code
19531 (Remove_Side_Effects): Expressions that involve packed arrays or records
19532 are copied at the point of reference, and therefore must be marked as
19533 renamings of objects.
19534 (Is_Predefined_Dispatching_Operation): Return false if the operation is
19535 not a dispatching operation.
19538 (Remove_Side_Effects): Lift enclosing type conversion nodes for
19539 elementary types in all cases.
19541 2006-02-13 Javier Miranda <miranda@adacore.com>
19543 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
19544 task types when accessing to the corresponding record type.
19545 Remove '!' in warning message.
19547 2006-02-13 Olivier Hainque <hainque@adacore.com>
19549 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
19550 to avoid useless and space inefficient overalignments on targets where
19551 Max_Alignment is larger than 16.
19553 2006-02-13 Pascal Obry <obry@adacore.com>
19555 * g-catiio.adb (Sec_Number): New type used to compute the number of
19556 seconds since 1-1-1970.
19557 (Image) [Natural]: The parameter was an Integer, as we can't deal with
19558 negative numbers (years, months...) it is better to have a Natural here.
19560 (Image) [Number]: Change parameter from Long_Integer to Number.
19561 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
19562 overflow for dates past year 2038.
19564 2006-02-13 Matthew Heaney <heaney@adacore.com>
19566 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
19569 2006-02-13 Arnaud Charlet <charlet@adacore.com>
19571 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
19573 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
19574 finalization can occur normally.
19576 2006-02-13 Vincent Celier <celier@adacore.com>
19578 * gnatcmd.adb (Rules_Switches): New table
19579 (Add_To_Rules_Switches): New procedure
19580 (GNATCmd): For command CHECK, put all options following "-rules" in the
19581 Rules_Switches table. Append these -rules switches after the -cargs
19584 2006-02-13 Robert Dewar <dewar@adacore.com>
19586 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
19587 These two cases were generating incorrect output, and if this unit
19588 was built with checks on, generated a discriminant mismatch constraint
19591 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19592 Robert Dewar <dewar@adacore.com>
19594 * lib-xref.adb (Get_Type_Reference): For a private type whose full
19595 view is an array type, indicate the component type as well, for
19596 navigation purposes.

19598 of violating pragma Unreferenced.
19599 Do not give Ada 2005 warning except on real reference.

19603 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
19604 main source, add switch -mdebug-main=_ada_ so that the executable can
19605 be debugged by the standard VMS debugger.
19606 (Gnatmake): Set No_Main_Subprogram to True when there is no main
19607 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
19608 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
19609 of the last source, as the binding and linking phases are never
19611 Set all executable obsolete when rebuilding a library.
19613 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
19616 2006-02-13 Javier Miranda <miranda@adacore.com>
19619 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
19620 code to improve the error message reported when the program has
19621 declarations of abstract interface types and it is not compiled with
19622 the -gnat05 switch.
19623 (P_Access_Definition): Reorganize the code to improve the error
19624 message reported when the new Ada 2005 syntax for anonymous
19625 access types is used and the program is not compiled with the

19641 * prj.adb (Reset): Initialize the first element of table Namings with
19642 the standard naming data.
19644 2006-02-13 Vincent Celier <celier@adacore.com>
19646 * prj.ads (Error_Warning): New enumeration type
19648 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
19649 unknown, use the location of the project to report the error.

19665 Prj.Nmsc.Check with parameter When_No_Sources.
19666 (Process): New parameter When_No_Sources. Call Check with parameter

19676 * prj-makr.adb (Make): Preserve the comments from the original project
19678 When removing nodes (attributes Source_Dirs, Source_Files,
19679 Source_List_File and package Naming), save the comments and attach the
19680 saved comments to the newly created nodes.
19681 Do not add a with clause for the naming package if one already exists.

19695 restriction No_Dispatching_Calls.
19696 (Override_Dispatching_Operation): Check for illegal attempt to override
19697 No_Return procedure with procedure that is not No_Return
19698 (Check_Dispatching_Call): Suppress the check for an abstract operation
19699 when the original node of an actual is a tag-indeterminate attribute
19700 call, since the attribute, which must be 'Input, can never be abstract.
19701 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
19702 call to the Input attribute (even when rewritten).
19703 (Propagate_Tag): Augment comment to indicate the possibility of a call
19704 to an Input attribute.
19706 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
19707 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.

19720 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
19721 handles default-initialized components to keep separate the management
19722 of this feature but also avoid the unrequired resolution and
19723 expansion of components that do not have partially initialized
19725 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
19726 (Check_Bounds): Likewise.
19727 (Check_Length): Likewise.
19729 2006-02-13 Javier Miranda <miranda@adacore.com>
19730 Ed Schonberg <schonberg@adacore.com>
19732 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
19733 abstract interface type call analyze_and_resolve to expand the type
19734 conversion into the corresponding displacement of the
19735 reference to the base of the object.
19736 (Eval_Attribute, case Width): For systems where IEEE extended precision
19737 is supported, the maximum exponent occupies 4 decimal digits.
19738 (Accessibility_Message): Add '\' in 2-line warning message.
19739 (Resolve_Attribute): Likewise.
19740 (case Attribute_Access): Significantly revise checks
19741 for illegal access-to-subprogram Access attributes to properly enforce
19742 the rules of 3.10.2(32/2).
19743 Diagnose use of current instance with an illegal attribute.
19745 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
19747 (Enclosing_Generic_Unit): New function to return a node's innermost
19748 enclosing generic declaration node.
19749 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
19750 (Type_Access_Level): The accessibility level of anonymous acccess types
19751 associated with discriminants is that of the current instance of the
19752 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
19753 (Compile_Time_Constraint_Error): Handle case of conditional expression.
19754 (Kill_Current_Values_For_Entity): New function
19755 (Enter_Name): Change formal type to Entity_Id

19759 Gary Dismukes <dismukes@adacore.com>
19761 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
19762 Analyze_Compilation_Unit.
19763 Detect and warn on redundant with clauses detected in a package spec
19764 and/or body when -gnatwr is used.
19765 (Analyze_Context): Analyze config pragmas before other items
19766 (Install_Context_Items): Don't analyze config pragmas here
19767 (Install_Limited_Withed_Unit): Set limited entity of package in
19768 with_clause so that cross-reference information or warning messages on
19769 unused packages can be properly generated
19770 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
19771 has Error_Posted set. Prevent infinite loops in illegal programs.
19772 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
19773 to the point of the error test requiring the current unit to be private.
19774 This ensures that private with clauses are not exempted from the basic
19775 checking for being a descendant of the same library unit parent as a
19776 withed private descendant unit.
19777 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
19778 handle private with clauses properly, as well as to account for cases
19779 where the withed unit is a public descendant of a private ancestor
19780 (in which case the current unit must be a descendant of the private
19781 ancestor's parent). The spec comments were updated accordingly. Also,
19782 the old error message in this subprogram was replaced with error
19783 messages that mirror the errors tested and reported by
19784 Check_Private_Child_Unit.
19785 Parameter and variable names improved for readability.
19786 (Install_Limited_Context_Clauses): Remove test for a withed unit being
19787 private as the precondition for calling
19788 Check_Private_Limited_Withed_Unit since that subprogram has been
19789 revised to test public units as well as private units.

19793 Ed Schonberg <schonberg@adacore.com>
19794 Javier Miranda <miranda@adacore.com>
19796 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
19797 that Scope_Stack.First = 1.
19798 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19799 were not always properly handled previously.
19800 (Formal_Entity): Complete rewrite, to handle properly some complex case
19801 with multiple levels of parametrization by formal packages.
19802 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
19803 to the corresponding derived type declaration for proper semantics.
19805 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
19806 (Check_Component): Enforce restriction on components of
19807 unchecked_unions: a component in a variant cannot contain tasks or
19809 (Unchecked_Union): Allow nested variants and multiple discriminants, to
19811 Add pragma Ada_2005 (synonym for Ada_05)
19812 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19813 were not always properly handled previously.
19814 Document that pragma Propagate_Exceptions has no effect
19815 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
19816 (Set_Convention_From_Pragma): Check that if a convention is
19817 specified for a dispatching operation, then it must be
19818 consistent with the existing convention for the operation.
19819 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
19820 longer required to specify an vtable-ptr component in the record. For
19821 compatibility reasons we leave the support for the previous definition.
19822 (Analyze_Pragma, case No_Return): Allow multiple arguments
19824 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
19825 non-overrideen inherited operation with a controlling result as
19826 illegal only its implicit declaration comes from the derived type
19827 declaration of its result's type.
19828 (Check_Possible_Deferred_Completion): Relocate the object definition
19829 node of the subtype indication of a deferred constant completion rather
19830 than directly analyzing it. The analysis of the generated subtype will
19831 correctly decorate the GNAT tree.
19832 (Record_Type_Declaration): Check whether this is a declaration for a
19833 limited derived record before analyzing components.
19834 (Analyze_Component_Declaration): Diagnose record types not explicitly
19835 declared limited when a component has a limited type.
19836 (Build_Derived_Record_Type): Code reorganization to check if some of
19837 the inherited subprograms of a tagged type cover interface primitives.
19838 This check was missing in case of a full-type associated with a private
19840 (Constant_Redeclaration): Check that the subtypes of the partial and the
19841 full view of a constrained deferred constant statically match.
19842 (Mentions_T): A reference to the current type in an anonymous access
19843 component declaration must be an entity name.
19844 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
19845 class_wide type to refer to full type, not to the incomplete one.
19846 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
19847 available. Required to give support to the certified run-time.
19848 (Analyze_Component_Declaration): In case of anonymous access components
19849 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
19850 (Process_Discriminants): For an access discriminant, use the
19851 discriminant specification as the associated_node_for_itype, to
19852 simplify accessibility checks.
19854 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19855 Javier Miranda <miranda@adacore.com>
19857 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
19858 abstract interpretations on an operator, remove interpretations that
19859 yield Address or a type derived from it, if one of the operands is an
19861 (Try_Object_Operation.Try_Primitive_Operation,
19862 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
19863 location when creating the new reference to a primitive or class-wide
19864 operation as a part of rewriting a subprogram call.
19865 (Try_Primitive_Operations): If context requires a function, collect all
19866 interpretations after the first match, because there may be primitive
19867 operations of the same type with the same profile and different return
19868 types. From code reading.
19869 (Try_Primitive_Operation): Use the node kind to choose the proper
19870 operation when a function and a procedure have the same parameter
19872 (Complete_Object_Operation): If formal is an access parameter and prefix
19873 is an object, rewrite as an Access reference, to match signature of
19874 primitive operation.
19875 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
19876 by an expanded name with prefix Standard, when the operands are of an
19877 anonymous access type.
19878 (Remove_Abstract_Operations): If the operation is abstract because it is
19879 inherited by a user-defined type derived from Address, remove it as
19880 well from the set of candidate interpretations of an overloaded node.
19881 (Analyze_Membership_Op): Membership test not applicable to cpp-class
19884 2006-02-13 Bob Duff <duff@adacore.com>
19886 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
19887 redundant use clauses.
19888 In particular, if the scope of two use clauses overlaps, but one is not
19889 entirely included in the other, we should not warn. This can happen
19890 with nested packages.
19891 (Analyze_Subprogram_Renaming): Protect the compiler against previously
19892 reported errors. The bug was reported when the compiler was built
19893 with assertions enabled.
19894 (Find_Type): If the node is a 'Class reference and the prefix is a
19895 synchronized type without a corresponding record, return the type
19898 2006-02-13 Javier Miranda <miranda@adacore.com>
19900 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
19901 if this is the full-declaration associated with a private declaration
19902 that implement interfaces, then the private type declaration must be
19904 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
19905 as aliased. The use of the 'access attribute is not available for such
19906 object (for this purpose the object should be explicitly marked as
19907 aliased, but being an anonymous type this is not possible).
19909 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19910 Robert Dewar <dewar@adacore.com>
19912 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
19913 compilation unit is an elaboration scope.
19914 (Add_Task_Proc): Add '\' in 2-line warning message.
19915 (Activate_All_Desirable): Deal with case of unit with'ed by parent
19917 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19918 Javier Miranda <miranda@adacore.com>
19920 * sem_type.adb (Write_Overloads): Improve display of candidate
19922 (Add_One_Interp): Do not add to the list of interpretations aliased
19923 entities corresponding with an abstract interface type that is an
19924 immediate ancestor of a tagged type; otherwise we have a dummy
19925 conflict between this entity and the aliased entity.
19926 (Disambiguate): The predefined equality on universal_access is not
19927 usable if there is a user-defined equality with the proper signature,
19928 declared in the same declarative part as the designated type.
19929 (Find_Unique_Type): The universal_access equality operator defined under
19930 AI-230 does not cover pool specific access types.
19931 (Covers): If one of the types is a generic actual subtype, check whether
19932 it matches the partial view of the other type.
19934 2006-02-13 Thomas Quinot <quinot@adacore.com>
19936 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
19937 line. This is necessary to allow In_Extended_Main_Unit to provide
19938 correct results for itypes while writing out expanded source.
19939 (Close_File): No need to update the source_index_table here since it's
19940 now done for each line.
19942 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19943 Robert Dewar <dewar@adacore.com>
19945 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
19946 preserve the source unit where the itype is declared, and prevent a
19948 (Note_Implicit_Run_Time_Call): New procedure
19949 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
19952 * sprint.ads: Document use of $ for implicit run time routine call

19956 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
19959 2006-02-13 Bob Duff <duff@adacore.com>
19961 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
19962 Scan_Unsigned, so we do not scan leading blanks and sign twice.
19963 Integer'Value("- 5") and Integer'Value("-+5") now correctly
19964 raise Constraint_Error.
19966 * s-vallli.adb (Scan_Long_Long_Integer): Call
19967 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
19968 do not scan leading blanks and sign twice.
19969 Integer'Value("- 5") and Integer'Value("-+5") now correctly
19970 raise Constraint_Error.
19972 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
19973 Scan_Long_Long_Unsigned): Split out most of the processing from
19974 Scan_Long_Long_Unsigned out into
19975 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
19976 This prevents scanning leading blanks and sign twice.
19977 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
19980 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
19981 out most of the processing from Scan_Unsigned out into
19982 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
19983 This prevents scanning leading blanks and sign twice.
19985 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
19986 use with Modular'Value attribute.
19987 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

20201 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
20202 non-tasking version of the soft link for task termination. We do
20203 nothing since if we are using the non-tasking version it

20205 (Null_Finalize_Global_List): Add this null version for the procedure
20206 in charge of finalizing the global list for controlled objects.

20208 instead for handling run-time termination in a more flexible way.
20209 (Adafinal_NT): This new procedure will take care of finalizing the
20210 global list for controlled objects if needed, but no tasking
20213 * s-tarest.adb (Task_Lock): Do not try to lock again the
20214 Global_Task_Lock if we already own it. Otherwise, we get blocked in
20215 some run-time operations.
20216 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
20217 until all nested locks have been released.
20218 (Task_Wrapper): Call the fall-back task termination handler. It

20226 moved to the Common_ATCB record.
20227 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
20228 Common_ATCB record.
20229 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the

20236 defined in Ada.Task_Termination, to avoid circular dependencies.
20237 (Termination_Handler): Redefine this type here, alredy defined in
20238 Ada.Task_Termination, for avoiding circular dependencies.
20239 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
20240 for storing task termination handlers. In addition,
20241 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to

20255 using the soft links mechanism.
20256 (Task_Wrapper): added dynamic stack analysis.
20258 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
20259 potentially blocking operations has been moved from
20260 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
20261 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
20262 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
20263 this run-time check.
20265 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
20266 of task termination procedure.

20314 (Displace): New subprogram that displaces the pointer to the object
20315 to reference one of its secondary dispatch tables.
20316 (IW_Membership): Modified to use the new table of interfaces.
20317 (Inherit_TSD): Modified to use the new table of interfaces.

20335 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
20336 in all the calls to Expand_Interface_Thunk. Instead of referencing the
20337 record component containing the tag of the secondary dispatch table we
20338 have to use the Offset_To_Top run-time function to get this information;
20339 otherwise if the pointer to the base of the object has been displace
20340 we get a wrong value if we use the 'position attribute.
20342 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
20343 all the calls to Expand_Interface_Thunk.
20344 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

20347 ensure that the interfaces implemented by the ancestors are placed
20348 at the header of the generated list.
20349 (Expand_Interface_Conversion): Handle the case in which the displacement
20350 associated with the interface conversion is not statically known. In

20378 RE_TK_Tagged, RE_TK_Task.
20380 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
20381 Init_Secondary_Tags_Internal to allow its use with interface types and
20382 also to generate the code for the new additional actual required
20383 by Set_Offset_To_Top.
20384 (Build_Init_Statements): In case of components associated with abstract
20385 interface types there is no need to generate a call to its IP.

20397 properly protected objects and attach handler in the case of the
20398 restricted profile.

20412 pointer initialization values. Make a SAVE_EXPR instead. Add comments
20413 about the use and expansion of SAVE_EXPRs in the various possible
20414 renaming handling cases.
20415 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
20416 abusing DECL_FCONTEXT.

20584 legal within a protected type that implements an interface.
20585 (Collect_Interfaces): Do not add to the list the interfaces that
20586 are implemented by the ancestors.
20587 (Derived_Type_Declaration): If the parent of the full-view is an
20588 interface perform a transformation of the tree to ensure that it has
20589 the same parent than the partial-view. This simplifies the job of the
20590 expander in order to generate the correct object layout, and it is
20591 needed because the list of interfaces of the full-view can be given in
20593 (Process_Full_View): The parent of the full-view does not need to be
20594 a descendant of the parent of the partial view if both parents are
20596 (Analyze_Private_Extension_Declaration): If declaration has an explicit
20597 "limited" the parent must be a limited type.
20598 (Build_Derived_Record_Type): A derived type that is explicitly limited
20599 must have limited ancestor and progenitors.

20670 * sem_cat.adb (Validate_RCI_Subprogram_Declaration): Revise test for
20671 available user-specified stream attributes on limited parameters to
20672 also test the type directly rather than only its underlying type (for
20673 Ada 95) and, in the case of Ada 2005, to check that the user-specified
20674 attributes are visible at the point of the subprogram declaration.
20675 For Ada 2005, the error message is modified to indicate that the
20676 type's stream attributes must be visible (again, only for -gnat05).

20709 the implementation of Ada 2005 synchronized types because
20710 concurrent types were never tagged types in Ada 95.

20838 * socket.c: Add extern int h_errno for rtems since networking header
20839 files are not available at this point in a tool bootstrap. Newlib

20935 may be platform-defined macros.
20936 For VxWorks, generate the OK and ERROR values.
20937 New constants giving the sizes of the components of C struct timeval.

20949 deal with different cases of static and dynamic elaboration checks (all
20950 checks does not count in the first case, but does in the second).

20956 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
20957 elementary types using the operator in standard. It is cleaner not to
20958 modify the programmers intent, especially in the case of floating-point.
20959 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
20960 it did not matter because we always rewrote a/=b to not(a=b).
20961 (Expand_Allocator_Expression): For an allocator expression whose nominal
20962 subtype is an unconstrained packed type, convert the expression to its
20963 actual constrained subtype.
20964 Implement warning for <= or >= where < or > not possible
20965 Fix to Vax_Float tests (too early in many routines, causing premature
20966 Vax_Float expansions.
20968 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
20969 to be used with packages and generic packages as well as with

20984 Allow optional = after -gnatm
20985 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
20986 longer sets Elaboration_Checks.
20987 Code to set warning mode moved to Sem_Warn
20988 so that it can be shared by pragma processing.
20990 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
20993 * s-taprop-solaris.adb:
20994 Change some <= to =, to avoid new warning

21002 * exp_vfpt.adb: Handle /= case
21003 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
21004 so that we do not get duplicate scaling for fixed point conversions.

21008 2005-11-14 Matthew Gingell <gingell@adacore.com>
21010 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
21011 Increase default priority on Lynx from 15 to 17, and meet the Ada
21012 requirement that Default_Priority be ((Priority'First +
21013 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

21110 from a fat or thin pointer type and a constrained object type.
21111 (annotate_value): Handle BIT_AND_EXPR.
21112 (annotate_rep): Don't restrict the back annotation of inherited
21113 components to the type_annotate_only case.
21114 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
21115 we are not defining the type.
21116 <E_Record_Type>: Likewise.
21117 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
21118 to get advantage of the new maybe_stabilize_reference interface, to
21119 ensure that what we reference is indeed stabilized instead of relying
21120 on assumptions on what the stabilizer does.
21121 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
21122 type imported through a limited_with clause, use its non-limited view.
21123 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
21125 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
21126 of #if sections + explicit comparisons of convention identifiers.
21127 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
21128 before early-returning for certain types when code generation is
21130 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
21131 nullification of gnu_expr we do for objects with address clause and
21132 that we are not defining.
21133 (elaborate_expression_1): Do not create constants when creating
21134 variables needed by the debug info: the dwarf2 writer considers that
21135 CONST_DECLs is used only to represent enumeration constants, and emits
21137 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
21138 object with an address clause into an indirect reference, drop the
21139 initializing expression.
21141 (STACK_CHECK_BUILTIN): Delete.

21150 if there is an actual subtype provided by the front-end, use that
21151 subtype to build an actual type with bounds template.
21152 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
21153 is provided by the front-end, use that subtype to compute the size of
21154 the deallocated object.
21155 (gnat_to_gnu): When adding a statement into an elaboration procedure,
21156 check for a potential violation of a No_Elaboration_Code restriction.
21157 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
21158 with extra arguments to control whether to recurse through non-values
21159 and to let the caller know if the stabilization has succeeded.

21161 maybe_stabilize, for common uses without restriction on lvalues and
21162 without need to check for the success indication.
21163 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
21164 pass false instead of 0 as the FORCE argument which is a bool.
21165 (Identifier_to_gnu): Remove checks ensuring that an renamed object
21166 attached to a renaming pointer has been properly stabilized, as no such
21167 object is attached otherwise.
21168 (call_to_gnu): Invoke create_var_decl to create the temporary when the
21169 function uses the "target pointer" return mechanism.
21170 Reinstate conversion of the actual to the type of the formal
21171 parameter before any other specific treatment based on the passing
21172 mechanism. This turns out to be necessary in order for PLACEHOLDER
21173 substitution to work properly when the latter type is unconstrained.

21393 Use Universal_Real instead of Long_Long_Float when we need a high
21394 precision float type for the generated code (prevents gratuitous

21396 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
21397 'Terminated for task interface class-wide objects. Generate a call to
21398 the predefined dispatching routine used to retrieve the _task_id from

21428 the return value into its actual subtype in order to help the backend

21459 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

21479 attribute of the N_Free_Statement.
21480 Generate itype for classwide designated object in both cases of

21663 rhs of an assignment even if the type is unconstrained, when the
21664 context is non-expanding.
21665 In an inlined body, if the context type is private,
21666 resolve with its full view, which must be a composite type.

21678 (Implicit_With_On_Parent): Do add duplicate with_clause on parent when
21679 compiling body of child unit.
21680 Use new class N_Subprogram_Instantiation

21703 (Inline_Instance_Body): Deinstall and record the use_clauses for all
21704 parent scopes of a scope being removed prior to inlining an instance
21706 (Analyze_Package_Instantiation): Do not perform front-end inlining when
21707 the current context is itself an instance within a non-instance child
21708 unit, to prevent scope stack errors.
21709 (Save_References): If the node is an aggregate that is an actual in a
21710 call, rewrite as a qualified expression to preserve some type
21711 information, to resolve possible ambiguities in the instance.
21712 (Instance_Parent_Unit): New global variable to record the ultimate
21713 parent unit associated with a generic child unit instance (associated

21721 not already set. Replace test of Is_Child_Unit with test of parent's
21722 scope against package Standard. Add comments and a ??? comment.
21723 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible

21741 (Build_Private_Derived_Type): The entity of the created full view of the
21742 derived type does not come from source. If after installing the private

21744 full view to construct the full declaration of the derived type.
21745 (Build_Derived_Record_Type): Relax the condition that controls the
21746 execution of the check that verifies that the partial view and

21756 (Process_Full_View): Rename local subprogram Find_Interface_In_
21757 Descendant to Find_Ancestor_Interface to leave the code more clear.
21758 Remove wrong code that avoids the generation of an error message
21759 when the immediate ancestor of the partial view is an interface.
21760 In addition some minor reorganization of the code has been done to
21761 leave it more clear.
21762 (Analyze_Type_Declaration): If type has previous incomplete tagged
21763 partial view, inherit properly its primitive operations.

21777 be included in the interface list.
21778 (Access_Definition): If the designated type is an interface that may
21779 contain tasks, create Master_Id for it before analyzing the expression
21780 of the declaration, which may be an allocator.

21791 subprogram declaration.
21792 Change name Is_Package to Is_Package_Or_Generic_Package
21793 (Process_Formals): A non null qualifier on a non null named access
21794 type is not an error, and is a warning only if Redundant_Constructs

21805 package associated with a generic instance or formal package, the
21806 private declarations of the parent must be installed (by calling new

21808 Change name Is_Package to Is_Package_Or_Generic_Package
21809 (Preserve_Full_Attributes): For a synchronized type, the corresponding

21815 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
21816 not try to rewrite a renamed stream attribute, because the operations
21817 on the type may not have been generated.
21818 Handle properly a renaming_as_body generated for a stream operation
21819 whose default is abstract because the object type itself is abstract.
21820 (Find_Type): If the type is incomplete and appears as the prefix of a
21821 'Class reference, it is tagged, and its list of primitive operations
21822 must be initialized properly.
21823 (Chain_Use_Clauses): When chaining the use clauses that appear in the
21824 private declaration of a parent unit, prior to compiling the private
21825 part of a child unit, find on the scope stack the proper parent entity
21826 on which to link the use clause.
21827 (Note_Redundant_Use): Emit a warning when a redundant use clause is
21829 (Analyze_Object_Renaming): An attribute reference is not a legal object

21847 a procedure call is used as a select statement trigger and is not an
21848 entry renaming or a primitive of a limited interface.
21849 (Valid_Conversion): If the operand has a single interpretation do not
21850 remove address operations.
21851 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
21852 statement to inhibit warning.
21853 (Resolve_Unary_Op): Do not produce a warning when
21854 processing an expression of the form -(A mod B)
21855 Use Universal_Real instead of Long_Long_Float when we need a high
21856 precision float type for the generated code (prevents gratuitous
21857 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
21858 (Resolve_Concatenation_Arg): Improve error message when argument is an
21859 ambiguous call to a function that returns an array.
21860 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

22444 (Expand_Allocator_Expression): Add tests for suppression of the AI-344
22445 check for proper accessibility of the operand of a class-wide allocator.
22446 The check can be left out if checks are suppressed or if the expression

22802 * checks.adb (Check_Needed): New procedure, deals with removing checks
22803 based on analysis of short-circuited forms. Also generates warnings for
22804 improper use of non-short-circuited forms.
22807 2005-09-01 Robert Dewar <dewar@adacore.com>
22809 * a-ztexio.adb, a-textio.adb, a-witeio.adb: Replace bad range checks
22812 2005-09-01 Robert Dewar <dewar@adacore.com>
22814 * errout.ads, errout.adb (Fix Error_Msg_F): Fix implementation to meet

22820 (Error_Msg_Warn): New variable for < insertion char.
22821 * prj-nmsc.adb: Implement new errout insertion char < (conditional
22823 (Check_For_Source): Change value of Source_Id only after the current
22824 source has been dealt with.
22826 2005-09-01 Robert Dewar <dewar@adacore.com>
22827 Doug Rupp <rupp@adacore.com>
22829 * exp_attr.adb: Handle vax fpt for 'Valid attribute

22835 Hristian Kirtchev <kirtchev@adacore.com>
22836 Javier Miranda <miranda@adacore.com>
22838 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
22839 from object notation, the original node is unanalyzed and carries no
22840 semantic information, so that accessiblity checks must be performed on
22841 the type of the actual itself.
22842 (Expand_N_Subprogram_Declaration): Change last actual parameter for
22843 compatibility with Build_Protected_Sub_Specification.
22844 (Check_Overriding_Inherited_Interfaces): Add suport to handle
22845 overloaded primitives.
22846 (Register_Interface_DT_Entry): Use the new name of the formal
22847 the the calls to Expand_Interface_Thunk
22849 * exp_dbug.ads: Augment comments on encoding of protected types to
22850 include the generation of dispatching subprograms when the type
22851 implements at least one interface.
22853 * lib.ads: Extend information in Load_Stack to include whether a given
22854 load comes from a Limited_With_Clause.
22856 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
22857 whether a potential circularity is harmless, because it includes units
22858 loaded through a limited_with clause. Extends previous treatment which
22859 did not handle properly arbitrary combinations of limited and
22860 non-limited clauses.
22862 2005-09-01 Nicolas Setton <setton@adacore.com>
22864 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
22865 to be encoded as typ___XBLU_lowerbound__upperbound instead of
22866 typ___XB_lowerbound__upperbound.
22868 2005-09-01 Thomas Quinot <quinot@adacore.com>
22870 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
22871 dummy access formal for RACW/RAS TypeCode TSS.
22872 (Build_TypeCode_Call): Do not generate dummy null access actual for
22873 calls to the TypeCode TSS.
22875 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22877 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
22878 fully qualified name, to distinguish instances with the same local name.
22880 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
22883 2005-09-01 Robert Dewar <dewar@adacore.com>

22891 (Free): New deallocation procedure for filter elements
22892 (Close): Deallocate any existing filter for the concerned connection
22894 2005-09-01 Laurent Pautet <pautet@adacore.com>
22896 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
22897 position set is provided, we compute one in order to reduce the maximum
22898 length of the keys. This computation first selects a character
22899 position between 1 and the minimum length of the keys in order to
22900 avoid reducing one of the keys to an empty string.
22901 (Initialize, Compute): When the ratio V to K is too low, the algorithm
22902 does not converge. The initialization procedure now comes with a
22903 maximum number of iterations such that when exceeded, an exception is
22904 raised in Compute. The user can initialize this ratio to another value
22906 Reformating and updated headers.
22908 2005-09-01 Javier Miranda <miranda@adacore.com>
22910 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
22911 that given an entity T creates and returns an Itype that duplicates the
22912 contents of T. The returned Itype has the null-exclusion
22913 attribute set to True, and its Etype attribute references T
22914 to keep the association between the two entities.
22915 Update copyright notice
22917 * sem_aggr.adb (Check_Can_Never_Be_Null,
22918 Aggregate_Constraint_Checks, Resolve_Aggregate,
22919 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
22921 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

22924 Robert Dewar <dewar@adacore.com>
22925 Hristian Kirtchev <kirtchev@adacore.com>

22932 Call Set_Result_Definition instead of Set_Subtype_Mark.
22933 (P_Subprogram_Specification): Add parsing of anonymous access result
22934 plus null exclusions. Call Set_Result_Definition instead of
22937 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
22938 (P_Access_Type_Definition): Add parsing for an anonymous access result
22939 subtype, plus parsing for null exclusions. Call Set_Result_Definition
22940 instead of Set_Subtype_Mark.
22942 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
22943 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
22944 (Result_Definition): New function for N_Function_Specifications.
22945 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
22946 N_Function_Specification.
22947 (Set_Null_Exclusion_Present): Allow this flag for
22948 N_Function_Specification.
22949 (Set_Result_Definition): New procedure for N_Function_Specifications.
22950 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
22951 and N_Function_Specification.
22953 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
22954 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
22955 Add support for LIMITED NEW for Ada 2005 AI-419
22956 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
22957 syntax for anonymous access results.
22958 Replace Subtype_Mark field by Result_Definition in
22959 N_Function_Specification and N_Access_Definition specs.
22960 Add Null_Exclusion_Present to spec of N_Function_Specification.
22961 (Result_Definition): New function for N_Function_Specification and
22962 N_Access_Function_Definition.
22963 (Set_Result_Definition): New procedure for N_Function_Specification and
22964 N_Access_Function_Definition.
22966 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
22967 Result_Definition for cases of N_Access_Function_Definition and
22968 N_Function_Specification.
22969 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
22971 2005-09-01 Vincent Celier <celier@adacore.com>
22973 * lib-writ.adb: Update Copyright notice
22974 (Write_With_Lines): On platforms where file names are case-insensitive,
22975 record the file names in lower case.
22976 (Write_ALI): For D lines, on platforms where file names are
22977 case-insensitive, record the file names in lower case.
22979 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22980 Emmanuel Briot <briot@adacore.com>
22982 * lib-xref.adb (Output_Overridden_Op): Display information on
22983 overridden operation.

22987 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
22990 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
22991 overriding entity information.
22993 2005-09-01 Vincent Celier <celier@adacore.com>
22995 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
22996 including those that are inherited.
22998 2005-09-01 Robert Dewar <dewar@adacore.com>
23000 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
23002 * par-prag.adb: Implement new pragma Debug_Policy
23004 * sem_prag.adb Implement new pragma Debug_Policy
23005 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23006 Component_Size attribute specification. Give warning for ignored pragma
23009 * snames.h, snames.ads, snames.adb: Introduce entries in
23010 Preset_Names for Name_Disp_Asynchronous_Select,
23011 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23012 Name_Disp_Timed_Select.
23013 New pragma Debug_Policy
23015 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23017 Switch -gnata also sets Debug_Pragmas_Enabled
23019 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23020 handle an explicit -gnata when compiling predefined files.
23022 2005-09-01 Vincent Celier <celier@adacore.com>
23024 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23025 directories of projects that have no Ada sources.
23027 2005-09-01 Robert Dewar <dewar@adacore.com>
23029 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23030 (makes a difference for wide characters)
23032 * widechar.adb, widechar.ads:
23033 Add Wide_Char_Byte_Count feature to count chars vs bytes
23035 2005-09-01 Thomas Quinot <quinot@adacore.com>
23036 Ed Schonberg <schonberg@adacore.com>
23037 Robert Dewar <dewar@adacore.com>
23039 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23040 'Address attribute reference with an overloaded prefix, use the
23041 location of the prefix (not the location of the attribute reference) as
23042 the error location.
23043 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23044 a function renaming thereof, is a valid prefix for 'Size (where it is
23045 intepreted as a function call).
23046 (Statically_Denotes_Entity): New predicate to determine whether the
23047 prefix of an array attribute can be considered static.
23050 (Eval_Attr): Fix failure to evaluate Component_Size for
23051 unconstrained arrays (resulted in wrong value in packed case, since
23052 back end cannot handle this case)
23054 2005-09-01 Robert Dewar <dewar@adacore.com>
23056 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23057 error msgs for most common cases.
23058 Use new errout insertion char < (conditional warning)
23060 2005-09-01 Javier Miranda <miranda@adacore.com>
23061 Ed Schonberg <schonberg@adacore.com>
23063 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23064 become local to the whole package.
23065 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23066 the package was already analyzed the new algorithm "replaces" the
23067 real entities by the shadow ones. This is required to ensure that
23068 the order of these entities in the homonym chains does not change;
23069 otherwise we can have undefined references at linking time because
23070 in case of conflicts the external name of the entities will have
23071 a suffix that depends on the order of the entities in the chain.
23072 (Remove_Limited_With_Clause): Complementary code that completes the
23073 new algorithm and replaces the shadow entities by the real ones.
23074 (Install_Limited_Withed_Unit): When unchaining entities before the
23075 installation of the shadow entities, only regular entities of the
23076 public part must be taken into account. This is required to
23077 keep this routine in synch with the work done by Remove_Limited_
23079 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
23080 even if unit is analyzed, because the analysis of the unit is
23081 idempotent in any case, and the limited view of the unit may have to
23082 be installed for proper visibility.
23083 (Expand_Limited_With_Clause): Even if the unit in the implicit
23084 with_clause has been analyzed already, a limited view of the package
23085 must be built for the current context, if it does not exist yet.
23087 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23088 Javier Miranda <miranda@adacore.com>
23089 Gary Dismukes <dismukes@adacore.com>
23091 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
23092 defining entity for the instance body, make a new defining identifier
23093 rather than copying the entity of the spec, to prevent accidental
23094 sharing of the entity list.
23095 (Check_Private_View): When exchanging views of private types, build the
23096 list of exchanged views as a stack, to ensure that on exit the exchanges
23097 are undone in the proper order.
23098 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
23099 Restore the compilation environment in case of instantiation_error.
23100 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
23101 for an anonymous access result.
23102 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
23103 (Formal_Entity): Handle properly the case of a formal package that
23104 denotes a generic package renaming.
23106 2005-09-01 Thomas Quinot <quinot@adacore.com>
23108 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
23109 clause if the array aggregate is surrounded by parentheses.
23111 2005-09-01 Cyrille Comar <comar@adacore.com>
23112 Gary Dismukes <dismukes@adacore.com>
23113 Ed Schonberg <schonberg@adacore.com>
23114 Javier Miranda <miranda@adacore.com>
23116 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
23118 to check if a type is Constrained in cases related to code generation
23119 (rather than semantic checking) since otherwise we do not generate
23120 similar code for mutable private types depending if their
23121 discriminants are visible or not.
23122 (Check_Abstract_Overriding): Do not complain about failure to override
23123 the primitive operations used in dispatching selects since they will
23124 always be overriden at the freeze point of the type.
23125 (Access_Definition): Separate out handling for resetting the scope
23126 of an anonymous access function result type. Retrieve the scope
23127 of the associated function rather than using Current_Scope, which
23128 does not have a consistent value (depends on whether we're in the
23129 middle of analyzing formal parameters). Add ??? comment about
23130 finding a cleaner way to handle the special cases of scope setting.
23131 (Process_Incomplete_Dependents): A protected operation is never a
23132 dispatching operation (only its wrapper may be).
23133 (Build_Derived_Record_Type): In case of tagged private types that
23134 implement interfaces add derivation of predefined primitive
23136 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
23137 by two parameters that are used in case of derivation from abstract
23138 interface types: No_Predefined_Prims is used to avoid the derivation
23139 of predefined primitives from the interface, and Predefined
23140 Prims_Only is used to complete the derivation predefined primitives
23141 in case of private tagged types implementing interfaces.
23142 Fix typo in comments
23143 (Find_Interface_In_Descendant): Protect the frontend against
23144 wrong code with large circularity chains.
23145 (Is_Private_Overriding): Add support for entities overriding interface
23146 subprograms. The test failed because Entities associated with overriden
23147 interface subprograms are always marked as hidden (and used to build
23148 the secondary dispatch table); in this case the overriden entity is
23149 available through the field abstract_interface_alias (cf. override_
23150 dispatching_operation)
23151 (Access_Definition): Set the scope of the type to Current_Scope for the
23152 case of a function with an anonymous access result type.
23153 (Access_Subprogram_Declaration): Handle creation of the type entity for
23154 an access-to-function type with an anonymous access result.
23155 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
23156 in handling for N_Access_Function_Definition.
23157 (Analyze_Subtype_Declaration): Modify the text of error message.
23158 (Derived_Type_Declaration): Modify the text of error message.
23159 (Process_Subtype): Modify the text of error message plus cleanup
23160 of one redundant error message.
23161 (Analyze_Component_Declaration): Code cleanup.
23162 (Analyze_Object_Declaration): Code cleanup.
23163 (Analyze_Subtype_Declaration): Propagate the null-exclusion
23164 attribute in case of access types. Code cleanup.
23165 (Array_Type_Declaration): Code cleanup.
23166 (Process_Discriminants): Create the new null-excluding itype
23167 if required. Code cleanup.
23168 (Process_Subtype): Create the new null-excluding itype if
23169 required. Code cleanup.
23170 (Build_Derived_Record_Type): Code cleanup to avoid calling
23171 twice the subprogram derive_subprograms in case of private
23172 types that implement interfaces. In this particular case the
23173 subprogram Complete_Subprograms_Derivation already does the
23174 job associated with the second call.
23176 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
23177 conversion to the full view when generating an operation for a
23178 discriminant whose type may currently be private.
23180 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23181 Javier Miranda <miranda@adacore.com>
23183 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
23184 V (Obj.F), the rewriting does not involve the indexed component, but
23185 only the selected component itself.
23186 Do not apply the transformation if the analyzed node is an actual of a
23187 call to another subprogram.
23188 (Complete_Object_Operation): Retain the entity of the
23189 dispatching operation in the selector of the rewritten node. The
23190 entity will be used in the expansion of dispatching selects.
23191 (Analyze_One_Call): Improve location of the error message associated
23193 (Analyze_Selected_Component): No need to resolve prefix when it is a
23194 function call, resolution is done when parent node is resolved, as
23196 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
23197 when attempting to resolve a call transformed from its object notation.
23198 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
23199 of the argument list for each interpretation of the operation.
23200 (Try_Object_Operation): The designated type of an access parameter may
23201 be an incomplete type obtained through a limited_with clause, in which
23202 case the primitive operations of the type are retrieved from its full
23204 (Analyze_Call): If this is an indirect call, and the return type of the
23205 access_to_subprogram is incomplete, use its full view if available.
23207 2005-09-01 Javier Miranda <miranda@adacore.com>
23208 Gary Dismukes <dismukes@adacore.com>
23210 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
23211 access types the null-exclusion and access-to-constant attributes must
23213 (Analyze_Return_Statement): When the result type is an anonymous access
23214 type, apply a conversion of the return expression to the access type
23215 to ensure that appropriate accessibility checks are performed.
23216 (Analyze_Return_Type): For the case of an anonymous access result type,
23217 generate the Itype and set Is_Local_Anonymous_Access on the type.
23218 Add ??? placeholder for check to disallow returning a limited object
23219 in Ada 2005 unless it's an aggregate or a result of a function call.
23220 Change calls from Subtype_Mark to Result_Definition.
23221 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
23222 Result_Definition in call to Make_Function_Specification.
23223 (Build_Body_To_Inline): Change Set_Subtype_Mark to
23224 Set_Result_Definition.
23225 (Make_Inequality_Operator): Change formal Subtype_Mark to
23226 Result_Definition in call to Make_Function_Specification.
23227 (Process_Formals): Create the new null-excluding itype if required.
23228 (New_Overloaded_Entity): For an entity overriding an interface primitive
23229 check if the entity also covers other abstract subprograms in the same
23230 scope. This is required to handle the general case, that is, overriding
23231 other interface primitives and overriding abstract subprograms inherited
23232 from some abstract ancestor type.
23233 (New_Overloaded_Entity): For an overriding entity that comes from
23234 source, note the operation that it overrides.
23235 (Check_Conformance, Type_Conformant): Addition of one new formal
23236 to skip controlling formals in the analysis. This is used to
23237 handle overloading of abstract interfaces.
23238 (Base_Types_Match): Add missing case for types imported from
23239 limited-with clauses
23240 (New_Overloaded_Entity): Add barrier to protect the use of
23241 the "alias" attribute.
23243 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23245 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
23246 verify that the procedure and the entry are mode conformant.
23247 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
23248 as a different operator, which is often a cut-and-paste error.
23250 2005-09-01 Javier Miranda <miranda@adacore.com>
23251 Ed Schonberg <schonberg@adacore.com>
23253 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
23254 used in controlling parameters exclude null because it is necessary to
23255 read the tag to dispatch, and null has no tag.
23256 (Override_Dispatching_Operation): If the previous operation is inherited
23257 from an interface, it becomes hidden and does not participate in later

23261 Ed Schonberg <schonberg@adacore.com>
23262 Gary Dismukes <dismukes@adacore.com>
23264 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
23265 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
23266 the expander will generate the corresponding run-time check to evaluate
23268 (Resolve_Call): Check for legal type of procedure name or prefix that
23269 appears as a trigger in a triggering alternative.
23270 (Valid_Conversion): If expression is ambiguous and the context involves
23271 an extension of System, remove System.Address interpretations.
23272 (Resolve_Qualified_Expression): Reject the case of a specific-type
23273 qualification applied to a class-wide argument. Enhance comment
23274 to explain checking of Original_Node.
23275 (Resolve_Type_Conversion): The location of the error message was not
23276 general enough to handle the general case and hence it has been removed.
23277 In addition, this patch improves the text of the message.
23278 (Resolve_Type_Conversion): Add missing support for access to interface
23280 (Resolve_Type_Conversion): If the target is a class-wide interface type,
23281 do not expand if the expression is the actual in a call, because proper
23282 expansion will take place when the call itself is expanded.
23283 (Resolve_Allocator): If the context is an unchecked conversion, the
23284 allocator inherits its storage pool, if any, from the target type of

23288 Javier Miranda <miranda@adacore.com>
23290 * sem_type.adb (Add_One_Interp): If a candidate operation is an
23291 inherited interface operation that has an implementation, use the
23292 implementation to avoid spurious ambiguities.
23293 (Interface_Present_In_Ancestor): In case of concurrent types we can't
23294 use the Corresponding_Record_Typ attribute to look for the interface
23295 because it is set by the expander (and hence it is not always
23296 available). For this reason we traverse the list of interfaces
23297 (available in the parent of the concurrent type).
23298 (Interface_Present_In_Ancestor): Handle entities from the limited view
23300 2005-09-01 Ed Schonberg <schonberg@adacore.com>

23305 primitive procedure of a limited interface with a controlling first
23307 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
23309 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
23310 capture if it is generated in the second operand of a short-circuit
23312 Do not capture values for variables with address clauses.
23313 (Is_Object_Reference): Treat a function call as an object reference only
23314 if its type is not Standard_Void_Type.
23316 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23318 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied

23542 view of the type to resolve the case alternatives.

24101 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
24102 longer protected objects. They have been replaced by lower-level
24103 suspension objects made up by a mutex and a condition variable (or
24104 their equivalent given a particular OS) plus some internal data to
24105 reflect the state of the suspension object.
24106 (Initialize, Finalize): Add this initialization procedure for
24107 Suspension_Object, which is a controlled type.
24108 (Finalize): Add the finalization procedure for Suspension_Object,
24109 which is a controlled type.
24111 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

24134 object to True, releasing the task that was suspended, if any.
24135 (Suspend_Until_True): Add this procedure that blocks the calling task
24136 until the state of the object is True. Program_Error is raised if
24137 another task is already waiting on that suspension object.
24138 (Initialize): Add this procedure for initializing the suspension
24139 object. It initializes the mutex and the condition variable which are
24140 used for synchronization and queuing, and it sets the internal state
24142 (Finalize): Add this procedure for finalizing the suspension object,
24143 destroying the mutex and the condition variable.

24364 associated with abstract interfaces.
24365 (Set_All_Interfaces_DTC_Entity): Removed. As part of the code
24366 clean up, the functionality of this subprogram is now provided

24369 within gdb to display the dispatch tables associated with a tagged
24371 (Collect_All_Interfaces): New subprogram that collects the whole list
24372 of interfaces that are directly or indirectly implemented by a tagged
24374 (Default_Prim_Op_Position): New subprogram that returns the fixed
24375 position in the dispatch table of the default primitive operations.
24376 (Expand_Interface_Actuals): New subprogram to generate code that
24377 displaces all the actuals corresponding to class-wide interfaces to
24378 reference the interface tag of the actual object.
24379 (Expand_Interface_Conversion): New subprogram. Reference the base of
24380 the object to give access to the interface tag associated with the
24381 secondary dispatch table.

24383 thunk. This is required for compatibility with the C+ ABI.
24384 (Make_Abstract_Interface_DT): New subprogram that generate the
24385 declarations for the secondary dispatch tables associated with an
24386 abstract interface.
24387 (Set_All_Interfaces_DTC_Entity): New subprogram that sets the DTC_Entity
24388 attribute for each primitive operation covering interface subprograms

24403 incorrectly setting the scope of an anonymous access component's type.
24404 (Process_Discriminants): Set Is_Local_Anonymous_Access for the type of
24405 an access discriminant when the containing type is nonlimited.
24406 (Make_Incomplete_Type_Declaration): Create an incomplete type
24407 declaration for a record type that includes self-referential access
24409 (Check_Anonymous_Access_Types): Before full analysis of a record type
24410 declaration, create anonymous access types for each self-referential
24412 (Analyze_Component_Declaration, Array_Type_Declaration): Indicate that
24413 an access component in this context is a Local_Anonymous_Access, for
24414 proper accessibility checks.
24415 (Access_Definition): Set properly the scope of the anonymous access type
24416 created for a stand-alone access object.
24417 (Find_Type_Of_Object): An object declaration may be given with an access
24419 (Complete_Subprograms_Derivation): New subprogram used to complete
24420 type derivation of private tagged types implementing interfaces.
24421 In this case some interface primitives may have been overriden

24511 * i-cpp.ads, i-cpp.adb:
24512 This package has been left available for compatibility with previous

24557 (Analyze_Subprogram_Body): Undo the previous work.
24558 (Analyze_Procedure_Call): If the call has the form Object.Op, the
24559 analysis of the prefix ends up analyzing the call itself, after which

24562 subprogram_specification that returns true if some non
24563 class-wide interface subprogram is found

24567 access to subprograms must be recursive.
24568 (Is_Unchecked_Conversion): Improve the test that recognizes
24569 instantiations of Unchecked_Conversion, and allows them in bodies that
24570 are to be inlined by the front-end. When the body comes from an

24593 object or component (that is, when Is_Local_Anonymous_Access is true).
24594 Prevent the special checks for conversions of access discriminants in
24595 the case where the discriminant belongs to a nonlimited type, since
24596 such discriminants have their accessibility level defined in the same
24597 way as a normal component of an anonymous access type.
24598 (Resolve_Allocator): When an allocator's designated type is a class-wide
24599 type, check that the accessibility level of type given in the
24600 allocator's expression or subtype indication is not statically deeper

24619 constant-folded, there is nothing to check.
24620 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
24621 check on possible violation of restriction No_Direct_Boolean_Operators
24622 until after expansion of operands, to prevent spurious errors when

24833 Factor common code across the stream-oriented attribute circcuits into
24834 a new subprogram, Analyze_Stream_TSS_Definition. The new uniform
24835 processing is functionally identical to the previous duplicated one,

24925 the "simple_choice" member in a variant record, in accordance with the
24926 description in the package spec: the information output for a constant
24927 should be "S number", not "SS number".
24928 (Get_Encoded_Name): Return at once if not generating code. Avoids name

24994 of the type is declared in a record (for determination of insertion
24996 (SO_Ref_From_Expr): Test whether Vtype denotes a partial or full view of

25023 againts previously reported critical errors in context clauses
25024 (Install_Limited_Withed_Unit): Code cleanup plus static detection
25025 of two further errors: renamed subprograms and renamed packages

25045 (Get_Type_Reference): For a subtype that is the renaming of an actual in
25046 an instantiation, use the first_subtype to ensure that we don't generate

25579 (check dos line terminator).
25580 (Check_Line_Max_Length): New procedure, split off from the existing
25581 Check_Line_Terminator routine. Separating this out allows -gnatyf to
25582 be properly recognized.
25584 * styleg.adb: Add ??? comment for line terminator reference

25627 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
25628 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
25629 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
25630 analyzed if expansion is disabled (which could otherwise cause spurious
25631 error messages if expansion has been disabled due to previous
25632 (unrelated) errors).
25634 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
25635 is disabled, the entity denoted by the argument is the access type
25636 itself, not an underlying record type, so there is no need to go back
25637 to the Corresponding_Remote_Type.
25639 2005-03-29 Gary Dismukes <dismukes@adacore.com>
25640 Robert Dewar <dewar@adacore.com>
25642 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
25643 expand a call to an instance of
25644 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
25645 Constructor actual of the instance. A class-wide membership
25646 check is also generated, to ensure that the tag passed to the instance
25647 denotes a type in the class.
25648 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
25649 of Name_Generic_Dispatching_Constructor.
25651 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
25652 05 unit for AI-260-02).

25664 character type cases.
25665 (Analyze_Subprogram_Renaming): Add special handling for
25666 the case of renaming of stream attributes when the renaming denotes a
25667 generic formal subprogram association for an abstract formal subprogram.
25668 Check that the attribute is a primitive stream attribute (and not
25669 a class-wide stream attribute) and then rewrite the attribute name
25670 as the name of the appropriate compiler-generated stream primitive.
25672 2005-03-29 Robert Dewar <dewar@adacore.com>
25674 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

25677 resulted in inaccurate result for unaligned scalars within records.
25679 2005-03-29 Ed Schonberg <schonberg@adacore.com>
25681 * freeze.adb (Freeze_Record_Type): If the type of the component is an
25682 itype whose parent is controlled and not yet frozen, do not create a
25683 freeze node for the itype if expansion is disabled.
25685 2005-03-29 Vincent Celier <celier@adacore.com>
25687 * make.adb (Gnatmake): Don't fail if the main project file is declared
25688 as having no Ada sources. Do not display message "no sources to
25689 compile" in quiet output.
25691 2005-03-29 Doug Rupp <rupp@adacore.com>
25693 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

25704 missing TYPE Improve the error message generated when compiling a
25705 limited interface in Ada83 or Ada95 mode.
25707 2005-03-29 Robert Dewar <dewar@adacore.com>
25709 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
25710 rather than proceed ahead using a junk attribute name.
25712 2005-03-29 Vincent Celier <celier@adacore.com>
25714 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
25716 * prj-part.adb (Parse_Single_Project): Set the location of a project
25717 on its defining identifier, rather than on the reserved word "project".
25719 * prj-proc.adb (Expression): Adapt to the fact that default of external
25720 references may be string expressions, not always literal strings.
25721 (Recursive_Process): Set Display_Name equal to Name
25722 when Location is No_Location, that is when there is no actual file.
25723 Get the Display_Name of the project from the source, when it is not a
25725 (Process): Use the Display_Name in error messages
25727 * prj-strt.adb (External_Reference): Allow default to be string
25728 expressions, not only literal strings.
25730 2005-03-29 Vincent Celier <celier@adacore.com>
25732 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
25733 file and the reference symbol file to be the same file.

25737 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
25738 forbid conversion of a local access-to-subprogram type to a remote one.
25740 * sem_util.adb (Wrong_Type): For a record type that is the expanded
25741 equivalent type for a remote access-to-subprogram type, go back to the
25742 original RAS entity when displaying an error message, so the casing is
25743 the original source casing.
25745 2005-03-29 Robert Dewar <dewar@adacore.com>
25747 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
25750 2005-03-29 Ed Schonberg <schonberg@adacore.com>
25752 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
25753 subtype if code is being pre-analyzed, to prevent un-expanded
25754 references to protected formals, among others.
25755 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
25756 interpretation that can be a call, include the result of the call as a
25757 possible interpretation of the dereference.
25759 * sem_ch5.adb (Process_Bounds): Determine type of range by
25760 pre-analyzing a copy of the original range, and then analyze the range
25761 with the expected type.
25763 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
25764 with an overloaded prefix where not all interpretations yield an
25765 access to subprogram, do not rewrite node as a call.
25766 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
25767 the node as a call once the context identifies the interpretation of
25768 the prefix whose call yields the context type.
25769 (Valid_Conversion): For the case of a conversion between
25770 local access-to-subprogram types, check subtype conformance using
25771 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
25772 detailed error message.
25774 2005-03-29 Ed Schonberg <schonberg@adacore.com>
25776 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
25777 indicator, indicate that the formal can never be null.
25778 (Process_Formals): If a formal has a non_null indicator, insert the
25779 resulting subtype immediately before the enclosing subprogram decl,
25780 and not at the beginning of the corresponding declarative part, to
25781 prevent access before elaboration (Ada2005).
25783 2005-03-29 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

26324 * a-reatim.ads, a-reatim.adb: Add functions Minutes and Seconds for
26327 * a-retide.ads: Minor comment changes
26329 2005-03-15 Robert Dewar <dewar@adacore.com>
26331 * a-stzunb.adb, a-stzunb.adb a-stzunb.ads, a-stzunb.ads,
26332 a-stwiun.ads, a-stwiun.adb, a-strunb.ads, a-strunb.adb: Move
26333 Realloc_For_Chunk to private part of package.
26334 New subprograms for AI-301
26336 * a-szuzti.adb, a-suteio.adb, a-swuwti.adb: Improve efficiency of
26337 Get_Line procedure.
26338 Avoid unnecessary use of Get/Set_Wide_String
26340 2005-03-15 Robert Dewar <dewar@adacore.com>
26343 * a-stunau.ads, a-stunau.adb:
26344 Change interface to allow efficient (and correct) implementation
26345 The previous changes to allow extra space in unbounded strings had
26346 left this interface a bit broken.
26348 * a-suteio.adb: Avoid unnecessary use of Get/Set_String
26350 * g-spipat.ads, g-spipat.adb: New interface for Get_String
26351 Minor reformatting (function specs)
26353 * g-spitbo.adb: New interface for Get_String
26355 * g-spitbo.ads: Minor reformatting
26357 * a-swunau.ads, a-swunau.adb: New interface for Get_Wide_String
26359 * a-szunau.ads, a-szunau.adb: New interface for Get_Wide_Wide_String
26361 2005-03-15 Javier Miranda <miranda@adacore.com>
26362 Robert Dewar <dewar@adacore.com>
26363 Thomas Quinot <quinot@adacore.com>
26364 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26366 * atree.ads, atree.adb: Add support for Elist24 field
26368 * atree.h: Fix wrong definition of Field27
26369 Add support for Elist16 field
26370 Add support for Elist24 field
26372 * einfo.ads, einfo.adb (Abstract_Interfaces,
26373 Set_Abstract_Interfaces): New subprograms.
26374 (Abstract_Interface_Alias, Set_Abstract_Interface_Alias): New
26376 (Access_Disp_Table, Set_Access_Disp_Table): Modified to handle a list of

26385 (Set_Task_Body_Procedure): New subprogram to set this attribute.
26386 (Has_Controlled_Component): Now applies to all entities.
26387 This is only a documentation change, since it always worked to apply
26388 this to other than composite types (yielding false), but now this is
26390 Update documentation on Must_Be_Byte_Aligned for new spec
26392 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
26393 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
26394 uses of the Access_Disp_Table attribute to reference the first dispatch
26395 table associated with a tagged type. As
26396 part of the implementation of abstract interface types,
26397 Access_Disp_Table has been redefined to contain a list of dispatch
26398 tables (rather than a single dispatch table).
26399 Similarly, upgrade all the references to Tag_Component by the
26400 new attribute First_Tag_Component.
26401 (Find_Inherited_TSS): Moved to exp_tss.
26402 Clean up test in Expand_N_Object_Declaration for cases
26403 where we need to do a separate assignment of the initial value.
26404 (Expand_N_Object_Declaration): If the expression in the
26405 declaration of a tagged type is an aggregate, no need to generate an
26406 additional tag assignment.
26407 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
26409 Bit packed array ops are only called if operands are known to be
26411 (Component_Equality): When returning an N_Raise_Program_Error statement,
26412 ensure that its Etype is set to Empty to avoid confusing GIGI (which
26413 expects that only expressions have a bona fide type).
26414 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
26415 determine the amount of data to be copied.
26417 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
26418 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
26419 INTERFACE_TYPE_DEFINITION ::=
26420 [limited | task | protected | synchronized] interface
26421 [AND interface_list]
26423 * par-ch3.adb (P_Type_Declaration): Modified to give support to
26425 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
26427 (P_Interface_Type_Definition): New subprogram that parses the new
26428 syntax rule of Ada 2005 interfaces
26429 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
26430 messages by the correct RENAMES (quotes removed).
26432 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
26433 attribute First_Tag_Component.
26435 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
26436 (Interface_List, Set_Interface_List): New subprograms.
26437 (Interface_Present, Set_Interface_Present): New subprograms.
26438 (Limited_Present, Set_Limited_Present): Available also in derived
26439 type definition nodes.
26440 (Protected_Present, Set_Protected_Present): Available also in
26441 record type definition and
26442 derived type definition nodes.
26443 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
26444 (Task_Present, Set_Task_Present): New subprogram.
26445 (Task_Body_Procedure): Removed.
26446 (Set_Task_Body_Procedure): Removed.
26447 These subprogram have been removed because the attribute
26448 Task_Body_Procedure has been moved to the corresponding task type
26449 or task subtype entity to leave a field free to store the list
26450 of interfaces implemented by a task (for AI-345)
26451 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
26452 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
26453 expression flag Do_Range_Check
26454 (Exception_Junk): Change to Flag7 to accomodate above change
26455 (Box_Present, Default_Name, Specification, Set_Box_Present,
26456 Set_Default_Name, Set_Specification): Expand the expression
26457 "X in N_Formal_Subprogram_Declaration" into the corresponding
26458 two comparisons. Required to use the csinfo tool.
26460 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
26461 "with string" given.
26463 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
26466 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
26469 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
26470 attribute Task_Body_Procedure rather than the old semantic field that
26471 was available in the task_type_declaration node.
26473 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
26474 interface type definitions.
26475 (P_Formal_Derived_Type_Definition): Modified to handle the list of
26478 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
26479 task type declaration.
26480 (P_Protected): Modified to handle the list of interfaces in a
26481 protected type declaration.
26483 2005-03-15 Doug Rupp <rupp@adacore.com>
26484 Vincent Celier <celier@adacore.com>
26486 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
26487 (Gen_Output_File_C): Likewise.
26488 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
26490 2005-03-15 Thomas Quinot <quinot@adacore.com>
26492 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
26493 is an N_Raise_Constraint_Error node, create a new copy of it without
26494 going through a call to Duplicate_Subexpr.
26496 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
26497 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26498 Nicolas Setton <setton@adacore.com>
26499 Ed Schonberg <schonberg@adacore.com>
26505 * decl.c (gnat_to_gnu_field): Reject aliased components with a
26506 representation clause that prescribes a size not equal to the rounded
26507 size of their types.
26508 (gnat_to_gnu_entity, case E_Component): Always look at
26509 Original_Record_Component if Present and not the entity.
26510 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
26511 of tagged extension types by not making field for components that are
26513 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
26514 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
26515 expression to the type of the object when the object is constant.
26516 Reverse defer_debug_incomplete_list before traversing it, so that trees
26517 are processed in the order at which they were added to the list. This
26518 order is important when using the stabs debug format.
26519 If we are deferring the output of debug information, also defer this
26520 output for a function return type.
26521 When adding fields to a record, prevent emitting debug information
26522 for incomplete records, emit the information only when the record is
26524 (components_to_record): New parameter defer_debug.
26525 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
26526 (gnat_to_gnu_field_decl): New function.
26527 (substitution_list, annotate_rep): Call it.
26528 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
26529 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
26530 No longer update discriminants to not be a COMPONENT_REF.
26531 (copy_alias_set): Strip padding from input type; also handle
26532 unconstrained arrays properly.
26534 * gigi.h (write_record_type_debug_info): New function.
26535 Convert to use ANSI-style prototypes. Remove unused
26536 declarations for emit_stack_check, elab_all_gnat and
26537 set_second_error_entity.
26538 (gnat_to_gnu_field_decl): New decl.
26540 * utils.c (write_record_type_debug_info): New function.
26541 (finish_record_type): Delegate generation of debug information to

26543 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
26544 (update_pointer_to): Fix pasto.
26545 (convert) <UNION_TYPE>: Accept slight type variations when
26546 converting to an unchecked union type.
26548 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
26549 replace the N_Freeze_Entity with a null statement.
26551 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
26552 within a constrained subcomponent of an enclosing record, place the
26553 freeze nodes in the scope stack entry for the enclosing record.
26554 (Undelay_Type): New Subprogram.
26555 (Set_Small_Size): Pass T, the type to modify; all callers changed.
26556 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
26557 within records; allow them to have freeze nodes if their base types
26560 * exp_util.adb (Remove_Side_Effects): Properly test for
26561 Expansion_Delayed and handle case when it's inside an
26562 N_Qualified_Expression.
26564 * sem_ch3.adb (Derived_Type_Declaration): New predicate
26565 Comes_From_Generic, to recognize accurately that the parent type in a
26566 derived type declaration can be traced back to a formal type, because
26567 it is one or is derived from one, or because its completion is derived
26569 (Constrain_Component_Type): If component comes from source and has no
26570 explicit constraint, no need to constrain in in a subtype of the
26572 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
26573 Minor change to propagate Is_Ada_2005 flag
26575 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
26576 Expansion_Delayed is False.
26577 (assoc_to_constructor): Ignore fields that have a
26578 Corresponding_Discriminant.
26579 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
26580 function returns "by target", dereference the target pointer using the
26581 type of the actual return value.
26582 <all>: Be prepared for a null gnu_result.
26583 (processed_inline_subprograms): Check flag_really_no_inline
26584 instead of flag_no_inline.
26585 (set_second_error_entity): Remove unused function.

26590 2005-03-15 Robert Dewar <dewar@adacore.com>
26591 Ed Schonberg <schonberg@adacore.com>
26592 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26594 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
26595 Must_Be_Byte_Aligned for cases where we do not need to use a
26596 System.Pack_nn unit.
26598 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
26600 Needed now that we do some processing for IN parameters as well. This
26601 may well fix some unrelated errors.
26602 (Expand_Call): Handle case of unaligned objects (in particular those
26603 that come from packed arrays).
26604 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
26605 renamed entity is an inherited operation, re-expand the call using the
26606 original operation, which is the one to call.
26607 Detect attempt to inline parameterless recursive subprogram.
26608 (Represented_As_Scalar): Fix to work properly with private types
26609 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
26610 accurate estimate. Yields True in far fewer cases than before,
26611 improving the quality of code that depends on this test.
26613 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
26614 over both visible and private declarations to remove them from tree,
26615 and mark subprograms declared in package as eliminated, to prevent
26616 spurious use in subsequent compilation of generic units in the context.
26618 * exp_util.ads: Minor cleanup in variable names
26620 * sem_eval.ads, sem_eval.adb: Minor reformatting
26621 (Compile_Time_Known_Bounds): New function
26623 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26625 * exp_ch7.adb (Convert_View): Use base types of underlying types when
26626 determining whether an unchecked conversion is needed for the argument
26627 of an initialization call.
26629 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26631 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
26632 that appears in the instantiation rather than the internal subtype
26633 generated in the wrapper package, to avoid anomalies in gigi when the
26634 target is derived from a private type whose full view is an access type.
26636 2005-03-15 Robert Dewar <dewar@adacore.com>
26638 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
26640 Add documentation to replace the use of this flag
26641 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
26644 2005-03-15 Thomas Quinot <quinot@adacore.com>
26646 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
26647 here from exp_attr so it can be shared between exp_attr and exp_dist.
26648 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
26649 all TSS names, not a subset thereof, and the previous name introduced
26650 an unnecessarily confusion that a distinction might exist between
26651 "OK" TSS names and some "not OK" TSS names.
26653 2005-03-15 Doug Rupp <rupp@adacore.com>
26655 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
26658 2005-03-15 Pascal Obry <obry@adacore.com>
26659 Eric Botcazou <ebotcazou@adacore.com>
26663 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
26664 when IN_RTS. This is to work around a bootstrap path problem.
26666 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
26667 table and pass it to __gnat_install_SEH_handler().
26668 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
26670 * lang.opt: Fix specification of -fRTS=.
26672 2005-03-15 Doug Rupp <rupp@adacore.com>
26673 Bernard Banner <banner@adacore.com>
26674 Vincent Celier <celier@adacore.com>
26675 Arnaud Charlet <charlet@adacore.com>
26678 This change works fine when gnatlib is built from the gcc directory,
26679 but does not work when using the libada Makefile, since GCC_FOR_TARGET
26680 is not passed to ada/Makefile.in, so more work is needed by a
26681 Makefile/configure expert.
26683 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
26684 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
26685 Setup gnatlink switch -M for x86_64 linux, as it is already setup
26687 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
26688 Run ranlib on libgccprefix.a
26689 Define PREFIX_OBJS for Darwin, to build libgccprefix.
26690 (ADA_INCLUDE_SRCS): Split Ada packages.
26692 2005-03-15 Robert Dewar <dewar@adacore.com>
26694 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
26696 * impunit.adb: Add GNAT.UTF_32
26698 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
26700 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
26701 now uses GNAT.UTF_32).
26703 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
26704 capabilities for categorizing characters using Unicode categories
26706 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26708 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
26709 instantiation that has been rewritten as a package body, retrieve spec
26710 to generate proper name for implicit_with_clause.
26711 (Install_Parents): Recognize a parent that is an instantiation but has
26712 been rewritten as a package declaration during analysis.
26714 2005-03-15 Javier Miranda <miranda@adacore.com>
26715 Ed Schonberg <schonberg@adacore.com>
26717 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
26718 parameter reported some error we immediately return. This improves the
26719 behaviour of the frontend in case of errors.
26720 (Install_Parent, Remove_Parent): Introduce new flag
26721 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
26722 ancestor of a generic child unit, when the child is being instantiated.
26723 (Inline_Instance_Body): If we are compiling the private
26724 part or the body of a child unit, restore the proper visibility of the
26725 parents after compiling the instance body.
26727 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26728 Javier Miranda <miranda@adacore.com>
26731 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
26732 of a private type, in which case it is underlying_type that denotes
26733 the proper task. Also modified to use the new entity attribute
26734 that is directly available in the task type and task subtype entities
26735 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
26736 arrays when other dimensions than the first are constrained by
26737 discriminants of an enclosing record.
26738 (Insert_Explicit_Dereference): If the prefix is an indexed component or
26739 a combination of indexed and selected components, find ultimate entity
26740 and generate the appropriate reference for it, to suppress spurious
26742 (Note_Possible_Modification): If an entity name has no entity, return.
26743 (Is_Variable): A function call never denotes a variable.
26744 (Requires_Transient_Scope): For record types, recurse only on
26745 components, not on internal subtypes that may have been generated for
26746 constrained components.
26748 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26750 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
26751 Eliminated as candidates for resolution. Both efficient, and avoids
26752 anomalies with operators declared in deleted code.
26753 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
26754 expansion is disabled (as when compiling a generic) to prevent spurious
26755 warnings on prefixes of selected components.
26757 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26759 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
26760 attached to a list before checking whether it appears in the private
26761 declarations of the current package.
26762 (Make_Inequality_Operator): Insert declaration in proper declarative
26763 list rather than just setting the Parent field, so that
26764 Is_Private_Declaration can handle it properly.
26766 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26768 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
26769 a renaming a body, check that the renamed subprogram in not intrinsic.
26770 (Find_Direct_Name): If several use_visible entities hide
26771 each other, and the context is a predefined file compiled through
26772 rtsfind, keep only the entity that comes from a predefined file.
26774 2005-03-15 Geert Bosch <bosch@adacore.com>
26776 * s-fatgen.adb (Valid): Extend special exceptions to account for long
26777 long float padding to also cover AMD64 and IA64.
26779 2005-03-15 Gary Dismukes <dismukes@adacore.com>
26781 * s-imgwch.adb: Add with and use of Interfaces.
26782 (Img_Wide_Character): Change type of Val to Unsigned_16.
26783 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
26785 2005-03-15 Matthew Gingell <gingell@adacore.com>
26787 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
26789 2005-03-15 Robert Dewar <dewar@adacore.com>
26791 * usage.adb: Add missing lines for -gnat95 and -gnat05 switches
26793 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
26795 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
26797 2005-03-15 Robert Dewar <dewar@adacore.com>
26799 * s-bitops.adb, s-bitops.ads,

27277 analysis of the name rewrites the node and analyzes it with the proper
27278 argument list. After analyzing the name, if the call has been rewritten
27279 and the result type is set, no further analysis is needed.
27280 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
27281 mark in function specification, in a context where the formals are
27282 visible and hide outer homographs.

27288 procedure", covering the case of a call to a formal abstract procedure
27289 that has statically tagged operands.
27290 (Check_Dispatching_Call): Check for the case of an actual given by
27291 a tag-indeterminate function call whose type is an ancestor of the
27292 containing call's associated tagged type. This situation can occur
27293 for inherited primitives with function defaults. In this case we
27294 use the tagged type's tag directly as the controlling argument for
27296 (Expand_Call): Name change on call to Expand_Dispatch_Call.
27298 * sprint.adb (Sprint_Node_Actual): Split
27299 N_Formal_Subprogram_Declaration into two alternatives for the new
27300 cases N_Formal_Abstract_Subprogram_Declaration and

27361 GNAT.OS_Lib.Set_Close_On_Exec.
27363 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
27364 the parent side as close-on-exec so that they are not inherited by the
27367 * g-os_lib.ads, g-os_lib.adb (Set_Close_On_Exec): New subprogram to
27368 set or clear the FD_CLOEXEC flag on a file descriptor.
27370 2005-02-09 Eric Botcazou <ebotcazou@adacore.com>
27371 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27375 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
27376 on the field if Pragma Component_Alignment (Storage_Unit).
27377 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
27378 side-effects as if it were a constant; also make SAVE_EXPR to protect
27380 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
27382 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.

27396 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27398 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
27399 component of an array of arrays in an assignment context, and the
27400 aggregate has component associations that require sliding on
27401 assignment, force reanalysis of the aggregate to generate a temporary
27402 before the assignment.
27403 (Must_Slide): Make global to the package, for use in Gen_Assign.
27405 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27407 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
27408 unchecked union with no inferable discriminants, return a
27409 Raise_Program_Error node, rather than inserting it at the point the
27411 (Expand_Record_Equality, Component_Equality): Handle properly the case
27412 where some subcomponent is an unchecked union whose generated equality
27413 code raises program error.
27415 2005-02-09 Doug Rupp <rupp@adacore.com>
27417 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.

27421 Arnaud Charlet <charlet@adacore.com>
27423 * init.c (__gnat_initialize): Add a new parameter eh which contains the
27424 address of the exception registration. The Win32 version of this
27425 routine calls __gnat_install_SEH_handler() to initialize the SEH
27426 (Structured Exception Handling) handler.
27427 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
27428 SEH (Structured Exception Handling) now.
27429 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
27430 (__gnat_initialize for ppc-vxworks): Adjust comments and the
27431 preprocessor condition protecting the call to the extra eh setup
27432 subprogram, which is only available for the ppc target.
27433 (__gnat_clear_exception_count): replaced reference to
27434 variable taskIdCurrent by call to taskIdSelf(), cleaner.
27436 * seh_init.c: New file.
27438 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
27439 (GNATBIND_OBJS): Idem.
27441 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
27442 routine takes a new parameter (a pointer to the exception registration
27443 for the SEH (Structured Exception Handling) support.
27445 * raise.h: (__gnat_install_SEH_handler): New prototype.
27446 Update copyright notice.
27448 * s-tassta.adb (Task_Wrapper): Declare the exception registration
27449 record and initialize it by calling __gnat_install_SEH_handler.

27474 -shared-libgcc is now used by default on some systems (e.g. linux with
27476 Remove references to Makefile.prolog/generic, no longer used.
27478 2005-02-09 Vincent Celier <celier@adacore.com>
27480 * prj-makr.adb (Process_Directory): Put file name in canonical case
27481 before matching against the patterns.
27482 If gnatname has been invoked as <prefix>-gnatname
27483 then invoke the compiler as <prefix>-gcc, not just "gcc".
27485 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27487 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
27488 with expansion disabled. The actual subtype is needed among other
27489 places when the selected component appears in the context of a loop
27490 bound, and denotes a packed array.
27491 (Operator_Check): Always use the first subtype in the
27492 error message, to avoid the appearance of internal base types.
27493 (Transform_Object_Operation): Copy each actual in full
27494 to the parameter associations of the constructed call, rather than
27495 using the shallow copy mechanism of New_Copy_List. This ensures that
27496 the chaining of named associations is done properly.
27497 (Complete_Object_Operation): Rewrite node, rather than
27498 replacing it, so that we can trace back to the original selected
27501 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
27502 and calls that use object notation, if the called function is not
27503 declared in a withed unit, place the elaboration constraint on the
27504 unit in the context that makes the function accessible.
27505 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
27506 imposes an elaboration constraint between two packages.
27508 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27510 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
27511 views of a private type after handling its private dependents, to
27512 maintain proper stack discipline between entry and exit from the
27515 2005-02-09 Cyrille Comar <comar@adacore.com>

27532 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
27533 Slight fix to documentation of -gnaty with no parameters
27535 * xr_tabls.ads: Add ??? comment for missing overall comment
27537 * xsinfo.adb: Make default file name be sinfo.h, since this is what
27538 we now use by default.
27540 * xsnames.adb: Adjust end of file test to look for five space followed
27541 by '#' instead of six spaces. The format of xsnames.adb was modified
27542 in the last update.
27544 * a-numeri.ads: Add reference to AI-388 for greek letter pi
27547 * clean.adb: Minor reformatting.
27549 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
27550 gnatname.adb: Minor reformatting
27551 Add 2005 to copyright output when utility is run
27553 * csets.adb: Eliminate obsolete comment
27555 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
27558 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
27560 2005-02-09 Sergey Rybin <rybin@adacore.com>
27562 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
27563 the difference between compact and incompact layout and add the record
27564 representation clause to the example illustrating different layouts.
27565 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
27566 component clauses").
27568 2005-02-09 Florian Villoing <villoing@adacore.com>
27570 * gnat_ugn.texi: Fix typos.
27571 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
27573 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
27574 in the generated documentation.
27576 2005-02-09 Arnaud Charlet <charlet@adacore.com>
27578 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

27618 * exp_util.ads: Minor correction in comment.
27620 2005-02-09 Arnaud Charlet <charlet@adacore.com>
27622 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
27623 since this procedure is now too complex to be worth inlining.

28257 flag. No longer needed now that we handle this in gnat1drv.adb.
28259 * repinfo.ads: Minor reformatting
28261 2004-12-07 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28262 Olivier Hainque <hainque@adacore.com>
28263 Eric Botcazou <ebotcazou@adacore.com>
28265 * decl.c (maybe_pad_type): Use TYPE_SIZE_UNIT of the input type for
28266 TYPE_SIZE_UNIT of result type if SIZE is not specified.
28267 (make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation
28268 of a bitfield, which we know is useless and causes trouble because of
28269 alignment implications.
28271 * utils.c (create_var_decl): Set DECL_COMMON again on targets without
28273 (process_attributes): Clear DECL_COMMON again when a section attribute
28275 (finish_record_type): Independently track if RECORD_TYPE has SIZE and/or
28276 SIZE_UNIT already set and use to compute final SIZE and SIZE_UNIT.
28277 (create_field_decl): Special case ADDRESSABLE negative to mean
28278 "no bitfield creation", to be used by make_aligning_type. Don't
28279 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
28280 fields claimed addressable still have to be bitfields. Use
28281 value_factor_p instead of a raw binop construction to check for the
28282 position's alignment.
28284 2004-12-07 Geert Bosch <bosch@adacore.com>
28286 * eval_fat.adb: Revert previous change.
28288 2004-12-07 Thomas Quinot <quinot@adacore.com>
28289 Ed Schonberg <schonberg@adacore.com>
28291 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
28292 with an implicit dereference as its prefix, use
28293 Insert_Explicit_Dereference instead of merely rewriting the prefix into
28294 an explicit dereference. This ensures that a reference to the original
28295 prefix is generated, if appropriate.
28297 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
28298 dereference is rewritten to an explicit one, generate a reference to
28299 the entity denoted by its prefix using the original prefix node, so
28300 the dereference can be properly recorded as a read of the denoted
28301 access value, if appropriate.
28303 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
28304 emitting 'assigned but never read' warning on a variable on the basis
28305 that it has an access type.
28306 (Check_References): Emit unreferenced warning when the scope is a
28309 2004-12-07 Robert Dewar <dewar@adacore.com>
28310 Ed Schonberg <schonberg@adacore.com>
28312 * exp_ch6.adb (Expand_Call): Add comment on handling of back end
28315 * exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
28316 leaving call unchanged.
28317 This deals with the case where the pragma Import specified
28318 an external name, to be handled by the back end.
28320 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
28321 subprogram which is Imported with convention Intrinsic if an
28322 External_Name argument is specified.
28323 (Process_Import_Or_Interface): Properly diagnose link name argument.
28324 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
28325 with Sem_Ch6.Cannot_Inline.
28326 (Process_Inline): Provide separate warning for inapplicable inline
28328 (Cannot_Inline): Reject subprograms that have an at_end handler, so that
28329 treatment is uniform on different targets.
28331 2004-12-07 Ed Schonberg <schonberg@adacore.com>
28333 * exp_ch7.adb (Expand_Cleanup_Actions): If statement sequence of
28334 construct is rewritten, preserve end label to permit source navigation.
28336 2004-12-07 Thomas Quinot <quinot@adacore.com>
28338 * exp_dist.adb (Specific_Build_General_Calling_Stubs,
28339 Specific_Build_Stub_Target): New subprograms.
28340 (Build_Subprogram_Calling_Stubs): Make this procedure independent from
28341 the PCS implementation used, using the above PCS-customized subprograms.
28342 Minor reformatting.
28343 (PolyORB_Support.Helpers): New subunit containing supporting subprograms
28344 for generation of DSA code targeted to the PolyORB PCS.
28345 (Add_Stub_Type): Rewrite to isolate the parts that are specific to one
28346 implementation of the partition communication subsystem in ancillary
28348 (Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,
28349 PolyORB_Support.Build_Stub_Type): New subrograms containing the
28350 PCS-specific part of Add_Stub_Type.
28351 (Insert_Partition_Check): Use runtime library function to perform
28354 * rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref
28355 (RE_Same_Partition): New entity, from s-parint.
28357 * s-parint.ads, s-parint.adb (Same_Partition): New subprogram.

28367 * g-os_lib.adb (Spawn): Explicitly initialize Saved_Error to avoid a
28368 compile-time warning.
28370 2004-12-07 Robert Dewar <dewar@adacore.com>
28372 * g-regpat.adb: (Match): Change a misuse of or to or else
28374 2004-12-07 Ed Schonberg <schonberg@adacore.com>
28377 (Generate_Reference): Handle properly a reference to an entry formal,
28378 when an accept statement has a pragma Unreferenced for it.
28380 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
28381 and the Has_Pragma_Unreferenced flag for each formal before analyzing
28382 the body, to ensure that warnings are properly emitted for each accept
28383 statement of a given task entry.
28385 2004-12-07 Vasiliy Fofanov <fofanov@adacore.com>
28387 * Makefile.in: Add support for foreign threads on VMS.
28389 2004-12-07 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28391 * misc.c (gnat_types_compatible_p, LANG_HOOKS_TYPES_COMPATIBLE_P):

28403 * nlists.adb (Prepend_Debug): Remove parameters and nest within
28405 (Remove_Next_Debug): Same fix
28407 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
28408 maintain back pointers now, though we did not used to, and comments
28410 (Prepend): Remove pragma Inline.
28411 (Remove_Next): Same cleanup
28413 2004-12-07 Thomas Quinot <quinot@adacore.com>
28415 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
28416 used to record an implicit dereference as a read operation on its
28417 prefix when operating under -gnatc. Necessary to avoid spurious
28418 'variable assigned but never read' warnings in that mode.
28419 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
28420 is a non-overloaded implicit dereference, call the above subprogram to
28421 ensure proper recording of references.
28423 2004-12-07 Gary Dismukes <dismukes@adacore.com>
28425 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
28426 to be resolved later as part of Analyze_Iteration_Scheme's call to
28429 2004-12-07 Ed Schonberg <schonberg@adacore.com>
28431 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

28442 documentation of the behaviour of these functions when passed an IP
28443 address that has no record in the system hosts database and no reverse

28463 2004-12-07 Vincent Celier <celier@adacore.com>
28464 Sergey Rybin <rybin@adacore.com>
28466 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
28467 Files" with the new tool and package names.
28468 Reformatting to suppress most of the warnings for line too long
28469 Document the new section "Project Search Path:" in the output of
28471 Add gnatmetric section
28473 2004-12-07 Vincent Celier <celier@adacore.com>
28475 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
28476 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
28477 and -eit to -ept. Added qualifier
28478 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
28480 2004-11-27 Andreas Schwab <schwab@suse.de>
28482 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
28484 2004-11-25 Arnaud Charlet <charlet@adacore.com>
28486 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
28487 internal implementation unit GNAT.Sockets.Thin,
28488 as their usage for sockets is non-portable (using the read and write
28489 functions from the system runtime library is fine on UNIX but won't
28490 work under Windows).
28492 * mingw32.h: Update copyright notice.
28494 2004-11-25 Arnaud Charlet <charlet@adacore.com>
28496 * ada-tree.h: Minor reformatting of previous change to avoid lines
28497 longer than 79 characters.

28530 (__gnat_dup2): New function.
28531 (__gnat_is_symbolic_link): Enable the effective body of this
28532 function when __APPLE__ is defined.
28534 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
28537 2004-11-18 Olivier Hainque <hainque@adacore.com>
28539 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
28540 address of which may be used to represent "others" and "all others"
28541 choices in exception tables, instead of the current harcoded
28542 (void *)0 and (void *)1.
28543 (Setup_Exception): Do nothing in the GNAT SJLJ case.
28545 * gigi.h (others_decl, all_others_decl): New decls representing the
28546 new Others_Value and All_Others_Value objects.
28547 (struct attrib): Rename "arg" component as "args", since GCC expects a
28548 list of arguments in there.
28550 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
28551 corresponding objects exported by a-exexpr, instead of hardcoded dummy
28554 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
28555 others_decl and all_others_decl instead of hardcoded dummy addresses
28556 to represent "others" and "all others" choices, which is cleaner and
28557 more flexible with respect to the possible eh pointer encoding policies.
28559 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
28560 (process_attributes): Account for the naming change of the "args"
28561 attribute list entry component.
28563 * decl.c (build_attr_list): Rename into prepend_attributes to allow
28564 cumulating attributes for different entities into a single list.
28565 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
28566 attributes for the current entity and propagate first subtype
28567 attributes to other subtypes.
28568 <E_Procedure>: Attribute arguments are attr->args and not
28569 attr->arg any more.
28570 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
28571 argument provided, as this is what GCC expects. Use NULL_TREE instead
28574 2004-11-18 Robert Dewar <dewar@adacore.com>
28576 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
28577 Minor reformatting througout (including new function specs)
28578 Add ??? comments asking for clarification.
28580 2004-11-18 Thomas Quinot <quinot@adacore.com>
28582 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
28583 incomplete duplicate implementation of this subprogram from butil.
28585 2004-11-18 Thomas Quinot <quinot@adacore.com>
28587 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
28588 procedures factors the common processing for building an RPC receiver
28589 for an RCI package or an RACW type.
28590 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
28591 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
28592 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
28594 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of

28602 string distribution identifiers assigned to a given subprogram.
28603 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
28604 (Add_RAS_Dereference_TSS): Add comments.
28605 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
28606 is not referenced yet because it will be used by the PolyORB DSA
28608 (Insert_Partition_Check): Remove fossile code.
28609 (First_RCI_Subprogram_Id): Document this constant.
28610 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
28612 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
28613 replaced with calls to Get_Library_Unit_Name_String. Previously there
28614 were several instances of the same code in different locations in the
28615 compiler; this checkin completes the replacement of all of these
28616 instances with calls to a common subprogram.
28617 Minor reformatting.
28619 * sem_dist.adb: Remove comment noting that RPC receiver generation
28620 should be disabled for RACWs that implement RASs.

28645 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
28646 (Expand_Pragma_Psect_Object): New procedure
28647 These procedures contain the revised and cleaned up processing for
28648 these two pragmas. This processing was formerly in Sem_Prag, but
28649 is more appropriately moved here. The cleanup involves making sure
28650 that the pragmas are properly attached to the tree, and that no
28651 nodes are improperly shared.
28653 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
28654 pragmas to Exp_Prag, which is more appropriate.
28655 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
28656 check for duplicates Remove use of Is_Psected flag, no longer needed.
28657 Use new Make_String_Literal function with string.
28659 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
28660 that are functions return universal values, that have to be converted
28661 to the context type.
28662 Use new Make_String_Literal function with string.
28663 (Get_Stream_Convert_Pragma): New function, replaces the use of
28664 Get_Rep_Pragma, which had to be kludged to work in this case.
28666 * freeze.adb: Use new Has_Rep_Pragma function
28668 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
28669 function with string.
28670 Use new Has_Rep_Pragma function.
28672 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes

28677 * errout.ads, errout.adb: (First_Sloc): New function
28679 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
28680 check (-gnatyx) instead of being included as a redundant construct
28683 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
28684 Style_Check_Order_Subprograms.

28694 Robert Dewar <dewar@adacore.com>
28696 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
28697 discriminant of a constrained subtype, analyze the copy of the
28698 corresponding constraint, because in some cases it may be only
28699 partially analyzed.
28700 Removes long-lived ??? comments.
28702 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
28703 handled controlled or secondary-stack expressions within the
28704 iteration_scheme of a loop.
28706 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
28707 bounds that may contain functions calls, to prevent memory leaks when
28708 the bound contains a call to a function that uses the secondary stack.
28709 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
28710 generate temporaries for loop bounds that might contain function calls
28711 that require secondary stack and/or finalization actions.
28713 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
28714 selected component and the selector is overloadable (not just a
28715 function) treat as function call, Analyze_Call will disambiguate if
28717 (Analyze_Selected_Component): Do not generate an actual subtype for the
28718 selected component if expansion is disabled. The actual subtype is only
28719 needed for constraint checks.
28720 (Analyze_Allocator): If restriction No_Streams is set, then do
28721 not permit objects to be declared of a stream type, or of a
28722 composite type containing a stream.
28724 * restrict.ads: Remove the a-stream entry from Unit_Array, since
28725 No_Streams no longer prohibits with'ing this package.
28727 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
28728 discriminants, but the parent base has unknown discriminants, there is
28729 no discriminant constraint to inherit. Such a discrepancy can arise
28730 when the actual for a formal type with unknown discriminants is a
28731 similar private type whose full view has discriminants.
28732 (Analyze_Object_Declaration): If restriction No_Streams is set, then
28733 do not permit objects to be declared of a stream type, or of a
28734 composite type containing a stream.
28736 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28738 * exp_dbug.ads: Update documentation to reflect simpler encoding for
28739 protected operations.
28741 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
28742 generated name, it complicates decoding in gdb and hinders debugging
28743 of protected operations.
28744 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
28745 flag for the protected entry barrier function.
28746 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info

28753 * Makefile.in: Inform the value of the variable GMEM_LIB in the
28754 Darwin-specific section.
28756 * lang-specs.h: Change the placement of the %1 marker.
28757 Works around the fact that gcc adds -fPIC by default under Darwin.

28761 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
28762 type of the object with the packed array type, set the Analyzed flag
28763 on the object if it is an entity or simple indexed component, to avoid
28764 spurious type errors.
28766 2004-11-18 Gary Dismukes <dismukes@adacore.com>
28768 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
28769 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
28770 separate line from the version message.
28772 2004-11-18 Ed Falis <falis@adacore.com>
28774 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
28776 (init_float): Eliminate initialization of floating point status for
28777 AE653. The instructions have no effect for vThreads.
28779 2004-11-18 Vincent Celier <celier@adacore.com>
28781 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
28782 gnatbind is invoked with -shared.
28784 2004-11-18 Jose Ruiz <ruiz@adacore.com>
28786 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
28787 for Detect_Blocking which is redundant with the check done within the
28788 procedure Protected_Single_Entry_Call.
28789 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
28790 Detect_Blocking which is redundant with the check done within the
28791 procedure Protected_Single_Entry_Call.
28793 2004-11-18 Vincent Celier <celier@adacore.com>
28795 * makegpr.adb (Compile): Put the compiling switches (in package
28796 Compiler and on the command line) immediately after "-c", instead of
28797 at the end of the command line invocation of the compiler, when
28798 compiling a non-Ada file.
28799 (Build_Global_Archive): When there is no need to rebuild the archive,
28800 set Global_Archive_Exists, so that the archive is passed to the linker
28803 2004-11-18 Robert Dewar <dewar@adacore.com>
28804 Sergey Rybin <rybin@adacore.com>
28807 Remove extra paren check from list of checks for redundant constructs
28808 Add documentation of new -gnatyx style check (check extra parens)
28809 Remove paragraph about gnatelim debug options.
28811 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
28812 objects rather than forbidding dependencies on the package Ada.Streams.
28814 * sinfo.ads: Add ??? note that we should document pragmas passed to
28817 * g-expect.ads: Fix a few typos in the comments.
28819 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
28821 * misc.c (gnat_handle_option): Use %< and %> for quoting in
28824 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
28826 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
28828 2004-11-07 Andreas Schwab <schwab@suse.de>
28830 * Makefile.in (install-gnatlib): Remove spurious hyphen.
28832 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
28835 * Makefile.in (darwin): Set soext to .dylib.
28837 2004-10-26 Vincent Celier <celier@gnat.com>
28838 Thomas Quinot <quinot@act-europe.fr>
28840 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
28841 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
28842 there is no use of GNAT.Sockets.Constants.
28843 Remove remaining pragma Import for C_Write
28844 Remove C_Read and C_Write from internal implementation unit
28845 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
28846 the read and write functions from the system runtime library is fine
28847 on UNIX but won't work under Windows).
28849 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
28850 (Check_Selector): Use C_Recv instead of C_Read.
28851 Selectors are the GNAT.Sockets abstraction to perform a select()
28852 call on a set of descriptors. To allow abortion of an ongoing
28853 select operation, some data is written to a dedicated socket that
28854 is always monitored.
28855 Under Windows, the write and read library functions cannot operate
28856 on sockets, so we need to use send and recv instead, which is portable
28857 across all supported platforms.
28859 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
28860 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
28861 (using the read and write functions from the system runtime library is
28862 fine on UNIX but won't work under Windows).
28864 2004-10-26 Nicolas Setton <setton@act-europe.fr>
28866 * mlib-tgt-darwin.adb: New file.
28868 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
28869 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
28870 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
28871 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
28874 * Makefile.in: Add support for building shared libraries under Darwin.
28875 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
28876 the low level EH init subprogram to be called from __gnat_initialize.
28878 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
28879 indicates which options to pass to the archive indexer.
28881 * mlib-utl.adb: Add support for calling ranlib with additional
28882 options. This is needed for instance under Mac OS X.
28883 (Ranlib_Options): New global variable, used to store the potential
28884 options to pass to ranlib.
28885 (Ar): Use Ranlib_Options when spawning ranlib.
28886 (Initialize): Set the value of ranlib option.
28888 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
28890 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
28891 instead of 8K, to reflect the real potential needs for stack-checking
28894 2004-10-26 Pascal Obry <obry@gnat.com>
28896 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
28898 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
28899 Windows only the initial thread stack size can be set so it is good to
28900 start we a low stack size.
28901 The OS will adjust the size as needed.
28903 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
28904 Nicolas Setton <setton@act-europe.fr>
28906 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
28907 "__unix__" instead of "unix".
28908 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
28909 sections were just mistakenly ignored. The former is
28910 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
28911 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
28912 of hpux. This prevents an unwanted definition of the symbol
28913 convert_addresses in adaint.o.
28915 2004-10-26 Gary Dismukes <dismukes@gnat.com>
28917 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
28918 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
28920 2004-10-26 Cyrille Comar <comar@act-europe.fr>
28922 * a-filico.ads, a-filico.adb: fix incorrect header.
28924 2004-10-26 Javier Miranda <miranda@gnat.com>
28926 * a-ststio.ads: Fix typo in identifier
28928 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28930 * sem_ch4.adb: Minor reformatting.
28932 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28934 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
28935 enabled, check the result of unary and binary operations when the
28936 expression is the right-hand side of an assignment.
28938 2004-10-26 Vincent Celier <celier@gnat.com>
28940 * clean.adb (Delete): Do not output warnings when in quiet output and
28941 not in verbose mode.
28942 (Force_Deletions): New Boolean flag, defaulted to False
28943 (Delete): Only delete a file if it is writable, and when
28944 Force_Deletions is True.
28945 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
28946 (Usage): Line for new switch -f
28947 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
28950 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
28952 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
28953 JM type only if its size matches that of the wrapper. When a size is
28954 prescribed and the field is not aliased, remove the wrapper of a JM
28955 type only if the size is not greater than that of the packed array.
28956 (gnat_to_gnu_entity): Change the extension of packed array wrappers
28959 2004-10-26 Geert Bosch <bosch@gnat.com>
28961 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
28962 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
28963 (Pred): Implement in terms of Succ.
28965 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28967 * exp_aggr.adb (Safe_Component): An aggregate component that is an
28968 unchecked conversion is safe for in-place use if the expression of the
28969 conversion is safe.
28970 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
28971 be expandable in place even if the aggregate does not come from source.
28972 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
28973 designated object of an allocator in place, rather than building it
28974 first on the stack. The previous scheme forces a full copy of the array,
28975 and may be altogether unsusable if the size of the array is too large
28976 for stack allocation.
28978 2004-10-26 Robert Dewar <dewar@gnat.com>
28980 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
28981 compares if the component is atomic.
28983 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
28984 array assignment if the component type is atomic.
28986 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28987 Eric Botcazou <ebotcazou@act-europe.fr>
28989 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
28990 is aliased and is a by_reference type, do not pass by copy.
28991 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
28992 detect whether the call is in the right side of an assignment or
28993 the expression of an object declaration. Recurse on component
28994 association within aggregates.
28995 Call it in the condition that determines whether the temporary is
28996 necessary for correct stack-checking.
28998 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29000 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29001 RACW_Type, used in the PolyORB version.
29002 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29003 version and the GARLIC version.
29005 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29006 Rename RCI_Info to RCI_Locator for better consistency between the
29007 GARLIC and PolyORB versions of the distributed systems annex.
29008 (DSA_Implementation_Name): This enumeration lists the possible
29009 implementations of the Partition Communication Subsystem for the
29010 Distributed Systems Annex (DSA). The three available implementations
29011 are the dummy stub implementation (No_DSA), and two versions based on
29012 two different distribution runtime libraries: GARLIC and PolyORB. Both
29013 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29015 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29018 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29019 between the GARLIC and PolyORB versions of the distributed systems
29021 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29023 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29025 * gnat1drv.adb: Suppress calling the back end when
29026 Frontend_Layout_On_Target is true.
29028 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29030 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29031 Set_Read_Only): New subprograms.
29032 These new routines allow the user to set or unset the Owner execute
29033 and Owner write permission flags on a file.
29035 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29036 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29038 2004-10-26 Matthew Gingell <gingell@gnat.com>
29040 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29042 2004-10-26 Pascal Obry <obry@gnat.com>
29044 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29045 memory before the faulting page we properly test the process read
29046 access for this address using appropriate Win32 routine.
29047 (HPUX sections): guard with "__hpux__" instead of "hpux".
29049 2004-10-26 Robert Dewar <dewar@gnat.com>
29051 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29052 entry parameter if pragma Unreferenced set, since we do not properly
29053 handle the case of multiple parameters.
29055 2004-10-26 Vincent Celier <celier@gnat.com>
29057 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29058 (Ada_Objects_Path.Add): For a library project, add to the object path
29059 the library directory only if there is no object directory or if the
29060 library directory contains ALI files.
29061 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29063 2004-10-26 Vincent Celier <celier@gnat.com>
29065 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29066 extension of library projects.
29068 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29069 path defaults to ".:<prefix>/lib/gnat".
29070 (Parse): For an extending all project, allow direct import of a project
29071 that is virtually extended.
29073 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29074 the specified name is directly imported, return its ID. Otherwise, if
29075 an extension of this project is imported, return the ID of the
29078 2004-10-26 Robert Dewar <dewar@gnat.com>
29080 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
29081 (Sub3): New procedure, used by Scaled_Divide
29082 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
29083 correct more than one instance of failure to propagate carries
29085 (Double_Divide): Handle overflow case of largest negative number
29086 divided by minus one.
29088 * s-arit64.ads (Double_Divide): Document that overflow can occur in
29089 the case of a quotient value out of range.
29092 2004-10-26 Robert Dewar <dewar@gnat.com>
29094 * s-bitops.adb (Bit_Eq): Remove redundant check.
29096 * s-bitops.ads: Minor comment updates
29097 Change some occurrences of Address to System.Address
29099 * s-carsi8.ads: Fix minor cut-and-paste error in comments
29101 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29103 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
29104 accessibility check to prefix that is a protected operation.
29106 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29108 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
29109 empty, post message on stub.
29111 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29112 Javier Miranda <miranda@gnat.com>
29114 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
29115 current instance appears within a unit that is directly in the context
29117 Used to determine whether the body of the instance should be analyzed
29118 immediately after its spec, to make its subprogram bodies available
29119 for front-end inlining.
29120 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
29121 constraint is not allowed on the component type (AARM 12.5.3(3))
29123 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29125 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
29126 'Storage_Pool): enhance, document & limit detection of non-sharable
29129 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
29131 * s-pooglo.ads: Add more documentation now that this pool is properly
29134 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29136 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
29137 or protected type with discriminants, do not constrain the
29138 corresponding record type if the subtype declaration has no
29139 discriminant constraints. This can be the case in source code, or in
29140 the subtype declaration created to rename an actual type within an
29143 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29145 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
29146 different kind of stub (possibly wrong name for file), do not check
29148 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
29149 includes call to some function that returns an unconstrained type, do
29152 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29154 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
29155 appear in the code for the main unit. Dependencies among units in the
29156 context of the main unit are established when those other units are
29157 compiled. Otherwise spurious elaboration constraints can generate
29158 incorrect elaboration circularities.
29160 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29161 Ed Schonberg <schonberg@gnat.com>
29163 * sem_util.adb (Is_Aliased_View): Defend against the case where this
29164 subprogram is called with a parameter that is not an object name. This
29165 situation arises for some cases of illegal code, which is diagnosed
29166 later, and in this case it is wrong to call Is_Aliased, as that might
29167 cause a compiler crash.
29168 (Explain_Limited_Type): Refine previous fix to include
29169 inherited components of derived types, to provide complete information.
29171 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
29172 is the prival for a protected object.
29173 It is necessary to mark this entity as a variable, in addition to
29174 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
29175 modified to avoid checking the Aliased flag on entities that are not
29176 objects. (Checking that flag for non-objects is erroneous and could
29177 lead to a compiler crash).
29179 2004-10-26 Robert Dewar <dewar@gnat.com>
29181 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
29182 X_Frac = 0.5, then we know that the number X must be positive.
29183 (Succ): Remove the same redundant test, and also fix the primary test
29184 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
29186 (Decompose): Add fuller comments to spec
29188 2004-10-26 Pascal Obry <obry@gnat.com>
29190 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
29191 validity (process must have read access). Set to 0 in all other cases.
29192 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
29193 violation on Win32.
29194 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
29195 segmentation violation.
29197 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29199 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
29200 whose type is a constructed subtype of an aliased object with an
29201 unconstrained nominal subtype, convert the actual to the constructed
29202 subtype before taking its address.
29204 2004-10-26 Vincent Celier <celier@gnat.com>
29206 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
29207 (Is_Path_Name_Case_Sensitive): New function
29209 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
29210 (Base_Name, Simple_Name, Current_Directory, Compose,
29211 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
29214 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29215 Vasiliy Fofanov <fofanov@act-europe.fr>
29216 Vincent Celier <celier@gnat.com>
29218 * gnat_ugn.texi: Generalize "finding memory problems" section into a
29219 "memory management issues" section and document some of the useful
29220 memory pools provided as part of the GNAT library.
29221 Remove "virtual" from declaration of A::method2 in
29222 the simple example of Ada/C++ mixed system.
29223 Library Projects may be virtually extended: their virtual extensions
29224 are not Library Projects.
29225 Added section on extending project hierarchies.
29227 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
29229 * adaint.c (__gnat_get_libraries_from_registry): Cast value
29231 (__gnat_portable_spawn): Remove const.
29233 * mingw32.h (MAXPATHLEN): Check for previous definition.
29235 2004-10-17 Matthias Klose <doko@debian.org>
29237 * gnatvsn.ads: Set gnat library version to 4.0.
29239 2004-10-05 Vincent Celier <celier@gnat.com>
29241 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
29243 2004-10-04 Laurent Guerby <laurent@guerby.net>
29246 * Makefile.in: Define and use RANLIB_FLAGS.
29248 2004-10-04 Pascal Obry <obry@gnat.com>
29250 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
29251 other x86 platforms).
29253 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
29255 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
29256 in general and triggers stack alignment adjustment for thread entry
29257 points on targets where this is necessary.
29259 2004-10-04 Bernard Banner <banner@gnat.com>
29262 * Makefile.in: Add section for powerpc linux
29263 Add variant i-vxwork-x86.ads
29265 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
29267 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
29269 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
29270 table registration calls when need be. Ensures no reference to the crt
29271 ctors symbol are issued in the SJLJ case, which avoids possible
29272 undefined symbol errors in the case of modules to be statically linked
29275 2004-10-04 Javier Miranda <miranda@gnat.com>
29277 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
29278 in-line the code corresponding to subprogram Analyze_Actuals. In
29279 addition, analyze the actuals only in case of subprogram call.
29281 2004-10-04 Ed Falis <falis@gnat.com>
29283 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size

29295 (Check_Unreachable_Code): Handle case of block exit
29297 2004-10-04 Robert Dewar <dewar@gnat.com>
29299 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
29300 (XMatchD): Avoid warning for Logic_Error call
29302 2004-10-04 Robert Dewar <dewar@gnat.com>
29304 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
29305 consider expressions buried within a procedure actual to be an actual.
29306 This caused some blowups with uses of packed slices within a procedure
29309 2004-10-04 Robert Dewar <dewar@gnat.com>
29311 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
29312 longer need to be initialized to zero.
29313 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
29314 initialized to zero.
29316 * checks.adb (Expr_Known_Valid): Packed arrays are now always
29317 considered valid, even if the representation is modular. That's correct
29318 now that we no longer initialize packed modular arrays to zero.
29320 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
29321 suffixes. These are now documented as the only cases in which the
29322 debugger ignores outer records.
29323 Previously, the spec allowed arbitrary suffixes for this purpose.
29324 Change name of LJM to JM for packed array pad records
29325 Create separate section on packed array handling, and add a whole new
29326 set of comments to this section describing the situation with packed
29327 modular types and justification requirements depending on endianness.
29329 2004-10-04 Robert Dewar <dewar@gnat.com>
29331 * a-except.adb: Add a comment for last change
29333 * einfo.ads: Minor spelling correction in comment
29335 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
29337 * sem_ch11.adb: Fix a case of using | instead of \ for continuation

29344 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
29345 Inline_Always when in Configurable_Run_Time mode.
29347 * sem_prag.adb (Process_Convention): If entity is an inherited
29348 subprogram, apply convention to parent subprogram if in same scope.
29349 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
29350 when in Configurable_Run_Time mode.
29352 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29354 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
29355 class_wide type after component list has been inherited.

29359 * sem_ch12.adb (Check_Generic_Actuals): New predicate
29360 Denotes_Previous_Actual, to handle properly the case of a private
29361 actual that is also the component type of a subsequent array actual.
29362 The visibility status of the first actual is not affected when the
29363 second is installed.
29364 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
29365 make fully recursive the treatment of formals of packages declared
29367 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
29368 the above on exit from an instantiation.
29369 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
29370 current instantiation which is now complete.
29371 (Analyze_Package_Instantiation): No instantiated body is needed if the
29372 main unit is generic. Efficient, and avoid anomalies when a instance
29373 appears in a package accessed through rtsfind.
29375 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29377 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
29378 do not generate a declaration for a temporary if the call is part of a
29379 library-level instantiation.
29381 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29383 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
29384 searching for a limited component to flag.
29386 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
29387 expansion of Input, to account for the fact that the implicit call
29388 generated by the attribute reference must freeze the user-defined
29389 stream subprogram. This is only relevant to 'Input, because it can
29390 appear in an object declaration, prior to the body of the subprogram.
29392 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
29393 expansion can proceed and further errors uncovered.
29394 (Minor clean up): Fix cases of using | instead of \ for continuation
29397 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
29399 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
29401 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
29402 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
29403 Use gcc_assert and gcc_unreachable.
29405 * decl.c (gnat_to_gnu_entity, case object): Check and process a
29406 specified alignment before validating size.
29407 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
29408 stripped-down declaration for the type of the inner field when making
29411 * utils.c (finish_record_type): Do not compute the size in units
29412 incrementally. Instead compute it once for the rep clause case.
29413 Use gcc_assert and gcc_unreachable.
29415 2004-10-04 Vincent Celier <celier@gnat.com>
29417 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
29419 (Is_Valid_Path_Name): Take '/' as a directory separator.
29421 2004-10-04 Vincent Celier <celier@gnat.com>
29423 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
29424 (Extended_Project) only if Extended_Project is defined, to avoid
29426 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
29428 (Parse_Single_Project): Ditto.
29430 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
29431 Add_To_Project_Path for virtual projects.
29433 2004-10-04 Vincent Celier <celier@gnat.com>
29435 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

29439 parameter Options_2.
29441 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
29442 Build_Dynamic_Library with an empty Options_2.
29444 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
29447 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
29448 directory separator, if any.
29449 (Gprmake): Do not allow mains on the command line for library projects.
29450 Do not attempt to link when the project is a library project.
29451 (Library_Opts): New table to store Library_Options.
29452 (Build_Library): If Library_Options is specified, pass these options
29453 when building a shared library.
29455 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
29457 * s-tposen.adb (Service_Entry): The object must be always unlocked at

29474 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
29475 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
29476 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
29477 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
29478 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
29479 used to signal whether the compiler creates the required stacks and
29480 descriptors for the different tasks (when True) or it is done by the
29481 underlying operating system at run time (when False).
29482 It is initially set to False in all targets.
29484 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
29485 if it is supported by the target.
29486 (Make_Task_Create_Call): Pass the stack address if it has been
29487 previously created. Otherwise pass a Null_Address.
29489 * snames.adb: Add _stack.
29491 * snames.ads: Add Name_uStack. Required to allow the expander to
29492 statically allocated task stacks.
29494 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
29495 Stack_Address argument.
29496 Check that its value is equal to Null_Address because this target does
29497 not support the static stack allocation.
29499 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29501 * usage.adb: Change "pragma inline" to "pragma Inline" in information
29504 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29506 * exp_dist.adb: Split declaration of asynchronous flag out of
29507 Add_RACW_Read_Attribute.
29508 Minor reformatting for better alignment with PolyORB version.
29509 Store the entity for the asynchronous flag of an RACW, rather than the
29510 expression, in the asynchronous flags table. This will allow this flag
29511 to be used in other subprograms beside Add_RACW_Read_Attribute.
29513 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29515 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
29516 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
29517 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
29518 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
29519 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
29520 sockets constant MSG_NOSIGNAL (Linux-specific).
29521 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
29522 all Send operations.
29523 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
29524 from trigerring SIGPIPE.
29525 Rename components to avoid clash with Ada 2005 possible reserved
29527 (Check_Selector): When the select system call returns with an error
29528 condition, propagate Socket_Error to the caller.
29530 2004-10-01 Jan Hubicka <jh@suse.cz>
29532 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

29540 Change "pragma inline" to "pragma Inline" in information and error
29542 Minor reformatting.
29544 * freeze.adb (Check_Address_Clause): Remove previous change, not the
29545 right way of doing things after all.
29546 (Freeze_Entity): For object, set Is_Public for imported entities
29547 unless there is an address clause present.
29549 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
29551 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
29552 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
29553 ensures proper handling of types with rep clauses, which might have
29554 their TYPE_SIZE set already.
29556 2004-09-21 Robert Dewar <dewar@gnat.com>
29558 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
29559 packed array types in both little- and big-endian cases. This change
29560 ensures that we no longer count on the unused bits being initialized
29561 for such types (and in particular ensures that equality testing will
29562 only read the relevant bits).
29563 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
29564 These changes mean that we no longer need to initialize small packed
29566 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
29567 optimization to an LJM field as to its parent field.
29569 * ada-tree.h, trans.c, utils.c, utils2.c:
29570 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
29572 2004-09-20 Jan Hubicka <jh@suse.cz>
29574 * utils.c (gnat_finalize): Remove.
29575 (end_subprog_body): Directly call cgraph_finalize_function;
29576 do not lower the nested functions.
29578 2004-09-20 Robert Dewar <dewar@gnat.com>
29581 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
29582 if an address clause is present, since that means that the Import
29585 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
29587 * 5tsystem.ads: Removed, no longer used.
29589 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
29590 Zack Weinberg <zack@codesourcery.com>
29592 * ada-tree.def: Use tree_code_class enumeration constants
29593 instead of code letters.
29594 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
29595 Update for new tree-class enumeration constants.

29610 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
29611 an existing directory.
29612 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
29613 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
29614 Convert the result to File_Size.
29616 * prj.ads: (Project_Error): New exception
29618 * prj-attr.adb: Except in procedure Initialize, Fail comes from
29619 Prj.Com, not from Osint.
29620 (Attrs, Package_Attributes): Tables moved to private part of spec
29621 (Add_Attribute, Add_Unknown_Package): Moved to new child package
29623 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
29624 Prj.Project_Error after call to Fail.
29625 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
29626 Fail. Check that package name is not already in use.
29628 * prj-attr.ads: Comment updates to indicate that all subprograms may be
29629 used by tools, not only by the project manager, and to indicate that
29630 exception Prj.Prj_Error may be raised in case of problem.
29631 (Add_Unknown_Package, Add_Attribute): Moved to new child package
29633 (Attrs, Package_Attributes): Table instantiations moved from the body to
29634 the private part to be accessible from Prj.Attr.PM body.

29637 from new package Prj.Attr.PM.
29638 (Parse_Attribute_Declaration): Call Add_Attribute from new package
29641 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
29643 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
29644 instead of Elaboration_Checks).
29646 * a-calend.adb: Minor reformatting
29648 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

29706 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
29707 Common_ATCB record. It contains the dynamic level of protected action
29708 nesting for each task. It is needed for checking whether potentially
29709 blocking operations are called from protected operations.

29747 contains the required machinery for handling that.
29749 * sem_util.ads: Change comment associated to procedure
29750 Check_Potentially_Blocking_Operation.
29751 This procedure does not insert a call for raising the exception because
29752 that is currently done by the run time.
29754 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
29756 * init.c: Add the global variable __gl_detect_blocking that indicates
29757 whether pragma Detect_Blocking is active (1) or not (0). Needed for
29758 making the pragma available at run time.
29759 (__gnat_set_globals): Pass and update the detect_blocking parameter.
29761 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
29762 pragma Detect_Blocking is active.
29764 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
29766 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
29767 DB is found in the ali file. Any unit compiled with pragma
29768 Detect_Blocking active forces its effect in the whole partition.
29770 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
29771 Detect_Blocking is active and delay is called from a protected
29774 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
29775 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
29776 Detect_Blocking is active (0 otherwise).
29777 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
29778 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
29781 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
29783 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
29784 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
29787 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
29788 (Register_Receiving_Stub): Add Subp_Info formal parameter.
29789 Update API in placeholder implemetation of s-parint to reflect changes
29790 in distribution runtime library.
29792 * sem_ch3.adb (Expand_Derived_Record): Rename to
29793 Expand_Record_Extension.
29795 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
29796 primitive operations of potentially distributed object types that have
29797 non-controlling anonymous access formals.
29799 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
29801 New implementation of expansion for remote access-to-subprogram types,
29802 based on the RACW infrastructure.
29803 This version of sem_dist is compatible with PolyORB/DSA as well as
29806 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
29807 Asynchrronous that applies to a remote access-to-subprogram type, mark
29808 the underlying RACW type as asynchronous.
29810 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
29811 __gnat_using_gnu_linker to 1.
29813 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
29814 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

29820 * exp_ch3.adb (Expand_Derived_Record): Rename to
29821 Expand_Record_Extension.
29822 (Build_Record_Init_Proc.Build_Assignment): The default expression in
29823 a component declaration must remain attached at that point in the
29824 tree so New_Copy_Tree copies it if the enclosing record type is derived.
29825 It is therefore necessary to take a copy of the expression when building
29826 the corresponding assignment statement in the init proc.
29827 As a side effect, in the case of a derived record type, we now see the
29828 original expression, without any rewriting that could have occurred
29829 during expansion of the ancestor type's init proc, and we do not need
29830 to go back to Original_Node.
29832 * exp_ch3.ads (Expand_Derived_Record): Rename to
29833 Expand_Record_Extension.
29835 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

29838 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
29839 New subprograms. Used to create a proxy tagged object for a remote
29840 subprogram. The proxy object is used as the designated object
29841 for RAS values on the same partition (unless All_Calls_Remote applies).
29842 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
29843 System.Partition_Interface.Get_Unique_Remote_Pointer.
29844 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
29845 Renamed from Add_RAS_*_Attribute.
29846 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
29848 New implementation of expansion for remote access-to-subprogram types,
29849 based on the RACW infrastructure.
29851 * exp_dist.ads (Copy_Specification): Update comment to note that this
29852 function can copy the specification from either a subprogram
29853 specification or an access-to-subprogram type definition.
29855 2004-09-09 Ed Schonberg <schonberg@gnat.com>
29857 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
29858 in an instance, between an explicit subprogram an one inherited from a
29859 type derived from an actual.
29861 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
29862 add a polling call if the subprogram is to be inlined by the back-end,
29863 to avoid repeated calls with multiple inlinings.
29865 * checks.adb (Apply_Alignment_Check): If the expression in the address
29866 clause is a call whose name is not a static entity (e.g. a dispatching
29867 call), treat as dynamic.
29869 2004-09-09 Robert Dewar <dewar@gnat.com>
29871 * g-trasym.ads: Minor reformatting
29873 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

29879 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
29882 2004-09-09 Pascal Obry <obry@gnat.com>
29884 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
29885 enable map file generation. Add the right option to generate the map
29886 file if Map_File is set to True.
29888 * gnatdll.adb (Gen_Map_File): New variable.
29889 (Syntax): Add info about new -m (Map_File) option.
29890 (Parse_Command_Line): Add support for -m option.
29891 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

29907 2004-09-09 Cyrille Comar <comar@act-europe.fr>
29909 * opt.adb (Set_Opt_Config_Switches): Use Ada_Version_Runtime to compile
29912 * opt.ads: Add Ada_Version_Runtime constant used to decide which
29913 version of the language is used to compile the run time.
29915 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
29917 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
29918 of variable length temporaries for function return now that the
29919 back-end and gigi support it.

29970 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
29971 packed indexed component where array is an IN OUT formal. This
29972 generated garbage code previously.
29974 * gnat_ugn.texi: Document -fverbose-asm
29976 * gnat-style.texi: Minor updates (note that boolean constants and
29977 variables are joined with AND/OR rather than short circuit forms).
29979 2004-09-01 Ed Schonberg <schonberg@gnat.com>
29981 * exp_util.adb (Safe_Unchecked_Type_Conversion): Conversion is safe if

29994 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
29995 pragma Debug as an if statement with a constant condition, for
29996 consistent treatment of entity references contained within the
29997 enclosed procedure call.
29999 2004-09-01 Vincent Celier <celier@gnat.com>
30001 * bindgen.adb: (Set_EA_Last): New procedure
30002 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure
30004 (Gen_Adafinal_Ada): If no finalization, adafinal does nothing

30026 2004-09-01 Pascal Obry <obry@gnat.com>
30028 * gprcmd.adb (Extend): Do not output trailing directory separator. This
30029 is not needed and it confuses Windows GNU/make which does not report
30030 directory terminated by a slash as a directory.
30031 (gprcmd): Idem for "pwd" internal command.
30033 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
30034 target names rewrite to fix regressions with recent version of
30035 GNU/make. Starting with GNU/make 3.80 the pipe character was not
30036 handled properly anymore.

30086 2004-08-16 Pascal Obry <obry@gnat.com>
30088 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
30089 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
30090 option and not mdll anymore. Update comment.
30092 2004-08-16 Pascal Obry <obry@gnat.com>
30094 * bld.adb (Put_Include_Project): Properly handle directory separators
30097 2004-08-16 Ed Schonberg <schonberg@gnat.com>

30110 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
30112 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
30113 for a global aliased object with a variable size and an unconstrained
30114 nominal subtype, pretend there is no initializer if the one we have is
30115 incomplete, and avoid referencing an inexistant component in there. The
30116 part we have will be rebuilt anyway and the reference may confuse
30117 further operations.

30137 2004-08-13 Ed Schonberg <schonberg@gnat.com>
30139 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
30140 unit, this is an attempt to inline a construct that is not available in
30141 the current restricted mode, so abort rather than trying to continue.
30143 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
30144 discriminants that rename those of the parent, recover names of
30145 original discriminants for the constraint on the full view of the
30147 (Complete_Private_Subtype): Do not create a subtype declaration if the
30148 subtype is an itype.
30150 * gnat_rm.texi: Added section on implementation of discriminated
30151 records with default values for discriminants.
30153 2004-08-13 Ed Schonberg <schonberg@gnat.com>
30156 * sem_res.adb (Make_Call_Into_Operator): Handle properly the case where
30157 the second operand is overloaded.

30171 from complaining on potential uninitialized reference.
30172 Change calls to GNAT.Sockets.Thin.Is_Socket_In_Set to account for
30173 new specification and test explicitly for non-zero return value.
30175 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
30176 returning C.int, to avoid using a derived boolean type.
30178 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
30179 Duplicate_Subexpr_No_Checks in preference to direct use of
30180 Remove_Side_Effects and New_Copy_Tree.

30204 2004-08-09 Olivier Hainque <hainque@act-europe.fr>
30206 * decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Adjust condition to
30207 ignore overflows on low and high bounds of an index to also account for
30208 differences in signedness between sizetype and gnu_index_subtype.
30209 These are as legitimate as the ones caused by a lower TYPE_PRECISION
30212 2004-08-09 Robert Dewar <dewar@gnat.com>
30214 * s-solita.ads, s-solita.adb: Minor reformatting
30216 * gnat_rm.texi: Add documentation for pragma Profile (Restricted)
30217 Move pragma Restricted_Run_Time, No_Run_Time, Ravenscar to new
30218 obsolescent section
30219 Add note that No_Implicit_Conditionals does not suppress
30220 run time constraint checks.
30222 * vms_conv.ads: Minor reformatting
30224 * s-secsta.adb: Use SS_Ptr instead of Mark_Id as stack pointer (cleanup
30225 and necessary for following change).
30226 (Mark): Return new format Mark_Id containing sec stack address
30227 (Release): Use sec stack address from Mark_Id avoiding Self call
30229 * s-secsta.ads: Define SS_Ptr to be used instead of Mark_Id as stack
30230 pointer (cleanup and necessary for following change).
30231 Define Mark_Id as record containing address of secondary stack, that way
30232 Release does not need to find the stack again, decreasing the number of
30233 calls to Self and improving efficiency.
30235 * sem_util.ads: Add a ??? comment for Is_Local_Variable_Reference
30237 * sem_ch5.adb (Analyze_Case_Statement): Add circuitry to track value of
30238 case variable into the individual case branches when possible.

32840 operation when either operand is a literal, to avoid further
32843 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and

34390 * osint.adb (Executable_Prefix): Set Exec_Name to the current
34391 executable name when not initialized. Otherwise, use its current value.
34393 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
34394 initialize it to another executable name than the current one. This
34395 allows to configure paths for an executable name (gnatmake) different
34396 from the current one (gnatdist).
34398 2004-03-29 Ed Schonberg <schonberg@gnat.com>
34400 * exp_ch6.adb (Expand_Call): A call to a function declared in the
34401 current unit cannot be inlined if it appears in the body of a withed

34404 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
34405 information for protected (wrapper) operation as well, to simplify gdb
34408 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

34447 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
34448 attribute reference does not denote a subtype, it can be any
34449 expression that has a classwide type, potentially after an implicit
34450 dereference. In particular, the prefix can be a view conversion for
34451 a classwide type (for which Is_Object_Reference holds), but it can
34452 also be a value conversion for an access-to-classwide type. In the
34453 latter case, there is an implicit dereference, and the original node
34454 for the prefix does not verify Is_Object_Reference.
34456 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
34457 conversion of a discriminant-dependent component of a mutable object
34460 2004-03-25 Ed Schonberg <schonberg@gnat.com>
34462 * freeze.adb (Freeze_Entity): When an inherited subprogram is
34463 inherited, has convention C, and has unconstrained array parameters,

34481 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
34482 value expressions to ensure that calls within a component definition
34483 will be checked (since those are evaluated during the record type's

34535 declaration for a child subprogram body that acts as a spec, indicate
34536 that the entity in the declaration needs debugging information.
34538 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
34539 full view if the subtype is created for a constrained record component;
34540 gigi has enough information to construct the record, and there is no
34541 place in the tree for the declaration.
34543 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
34544 serial number for the dummy body that is built for analysis, to avoid

34582 Minor reformatting.
34584 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
34586 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
34587 as regular exception objects and not as mere integers representing the
34588 condition code. The latter approach required some dynamics to mask off
34589 severity bits, which did not fit well into the GCC table based model.
34590 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
34591 exception data objects. We don't it and it would conflict with the other
34592 external symbol we have to generate for such exceptions.
34594 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
34595 the special code for VMS exceptions, since these are now represented
34596 as regular exceptions objects.

34639 When needed (stack checking) the stack size is retrieved
34640 from the VxWorks kernel.
34642 * Makefile.in: Flag -nostdinc is required when building the run time
34643 for avoiding looking for files in the base compiler.
34644 Add the VxWorks specific version of the package body for
34645 System.Stack_checking.Operations (5zstchop.adb).
34647 * Make-lang.in: Add the object file for
34648 System.Stack_Checking.Operations.

34890 explicit dereference.
34891 (Expand_N_Slice): Same. Always do the rewriting, even for the case
34892 of non-packed slices, since the dereference action generated by
34893 expansion of the explicit dereference is needed in any case.

34895 analyze and resolve the rewritten explicit dereference so it is seen
34897 (Insert_Dereference_Action): This procedure is now called only for the

36251 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
36252 (Type_May_Have_Bit_Aligned_Components): New function.
36254 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

36262 importing constant atomic/volatile objects.
36263 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
36264 unless explicit Pure_Function pragma given, to avoid insidious bug of
36265 call to non-pure imported function getting eliminated.

36268 gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,
36269 gnatxref.adb, gprcmd.adb, gprep.adb, make.adb: Minor reformatting

36283 New switch Sec_Stack_Used (GNAT, GNATBIND)
36284 Make Default_Secondary_Stack_Size a variable instead of a constant,
36285 so that it can be modified by the new -Dnnn bind switch.
36287 * rtsfind.adb (Load_Fail): Give full error message in configurable
36288 run-time mode if all_errors mode is set. This was not done in the case
36289 of a file not found, which was an oversight.
36290 Note if secondary stack unit is used by compiler.
36292 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
36293 ineffective elaborate all pragmas on non-visible packages (this
36294 happened when a renamed subprogram was called). Now the elaborate all
36295 always goes on the package containing the renaming rather than the one
36296 containing the renamed subprogram.
36298 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
36299 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

36302 has an Etype that references an E_String_Literal.
36303 (Eval_String_Literal): Avoid assumption that N_String_Literal node
36304 always references an E_String_Literal_Subtype entity. This may not
36305 be true in the future.
36307 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
36310 * sem_res.adb (Resolve): Specialize msg for function name used in proc
36313 2004-01-05 Ed Falis <falis@gnat.com>

36318 2004-01-05 Vincent Celier <celier@gnat.com>
36320 * bld.adb: Minor comment updates
36321 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
36324 * make.adb (Gnatmake): Special process for files to compile/check when
36325 -B is specified. Fail when there are only foreign mains in attribute
36326 Main of the project file and -B is not specified. Do not skip bind/link
36327 steps when -B is specified.
36329 * makeusg.adb: Document new switch -B
36331 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
36333 * switch-m.adb: (Scan_Make_Switches): Process -B switch

36352 -gnatwa warning on static condition.
36354 2004-01-05 Doug Rupp <rupp@gnat.com>

36358 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
36360 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
36361 all attributes, including read-only attribute.

36366 library naming scheme.
36368 * mlib-prj.adb (Build_Library): Generate different names for the static
36369 or dynamic version of the GNAT runtime. This is needed to support the
36370 new shared library naming scheme.

36372 based on the new naming scheme.
36374 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
36375 scheme for the shared runtime libraries.
36378 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
36380 (install-gnatlib): Do not create symlinks for shared libraries.
36381 (gnatlib-shared-default): Idem.
36382 (gnatlib-shared-dual-win32): New target. Not used for now as the
36383 auto-import feature does not support arrays/records.
36384 (gnatlib-shared-win32): Do not create copy for the shared libraries.
36385 (gnatlib-shared-vms): Fix shared runtime libraries names.
36387 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
36388 dependent runtime shared library name.
36390 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
36392 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
36395 2004-01-05 Ed Schonberg <schonberg@gnat.com>
36397 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
36398 protected objects when allocator has a subtype indication, not a
36399 qualified expression. Note that qualified expressions may have to be
36400 checked when limited aggregates are implemented.
36402 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
36403 pure, emit warning.
36404 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
36405 subprogram is imported, remove warning.
36407 2004-01-05 Geert Bosch <bosch@gnat.com>
36409 * s-poosiz.adb: Update copyright notice.
36410 (Allocate): Use Task_Lock to protect against concurrent access.

36449 * cstand.adb (Create_Standard): Change the way how the declaration of
36450 the Duration type is created (making it the same way as it is for all
36451 the other standard types).
36453 2003-12-17 Robert Dewar <dewar@gnat.com>
36455 * s-crtl.ads: Fix header format
36456 Change Pure to Preelaborate

36461 the expression type only if it is declared in the current unit.
36463 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
36464 are universal and already analyzed, as can occur in constrained
36465 subcomponents that depend on discriminants, when one constraint is a
36468 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
36469 type Any_Fixed is legal as the argument of a conversion, if only one
36470 fixed-point type is in context.

36481 2003-12-15 Vincent Celier <celier@gnat.com>
36483 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
36484 (Gnatchop): Do not set failure status when reporting the number of
36487 2003-12-15 Doug Rupp <rupp@gnat.com>

36509 * Make-lang.in: Makefile automatically updated
36511 2003-12-11 Ed Falis <falis@gnat.com>
36513 * 5zinit.adb: Clean up.
36515 * 5zintman.adb (Notify_Exception): replaced case statement with a call
36516 to __gnat_map_signal, imported from init.c to support
36517 signal -> exception mappings that depend on the vxWorks version.
36520 Created and exported __gnat_map_signal to support signal -> exception
36521 mapping that is dependent on the VxWorks version.
36522 Change mapping of SIGBUS from Program_Error to Storage_Error on VxWorks
36524 2003-12-11 Vasiliy Fofanv <fofanov@act-europe.fr>

36550 Minor reformatting throughout
36552 2003-12-11 Ed Schonberg <schonberg@gnat.com>
36554 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
36555 bounds of a loop, create a separate block in order to generate proper
36556 cleanup actions to prevent memory leaks.
36558 * sem_res.adb (Resolve_Call): After a call to
36559 Establish_Transient_Scope, the call may be rewritten and relocated, in
36560 which case no further processing is needed.

36572 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
36575 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
36578 2003-12-08 Robert Dewar <dewar@gnat.com>
36580 * 7sintman.adb: Minor reformatting
36582 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
36583 standard linker options to get standard libraries linked. We now plan
36584 to provide dummy versions of these libraries to match the appropriate
36585 configurable run-time (e.g. if a library is not needed at all, provide
36586 a dummy empty library).
36588 * targparm.ads: Configurable_Run_Time mode no longer affects linker
36589 options (-L parameters and standard libraries). What we plan to do is
36590 to provide dummy libraries where the libraries are not required.
36592 * gnatbind.adb: Minor comment improvement
36594 2003-12-08 Javier Miranda <miranda@gnat.com>
36596 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
36597 aggregate in the parent. Otherwise constants with limited aggregates
36598 are not supported. Add new formal to pass the component type (Ctype).
36599 It is required to call the corresponding IP subprogram in case of
36600 default initialized components.
36601 (Gen_Assign): In case of default-initialized component, generate a
36602 call to the IP subprogram associated with the component.
36603 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
36604 of aggregate with default initialized components.
36605 (Has_Default_Init_Comps): Improve implementation to recursively check
36606 all the present expressions.
36608 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
36609 to indicate that the initialization call corresponds to a
36610 default-initialized component of an aggregate.
36611 In case of default initialized aggregate with tasks this parameter is
36612 used to generate a null string (this is just a workaround that must be
36613 improved later). In case of discriminants, this parameter is used to
36614 generate a selected component node that gives access to the discriminant
36617 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
36618 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
36619 allocated aggregates with default-initialized components.
36621 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
36622 the box notation is used in positional aggregates.

36639 (Parse): New Boolean parameter Store_Comments, defaulted to False.
36640 Set the scanner to return ends of line and comments as tokens, if
36641 Store_Comments is True.
36642 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
36643 comments are associated with these nodes. Store the node IDs in the
36645 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
36647 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
36648 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
36649 current project. Call Tree.Restore afterwards. Set the various nodes
36650 for comment storage (Next_End, End_Of_Line, Previous_Line,
36653 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
36654 defaulted to False.
36656 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
36657 to False. When Truncated is True, truncate the string, never go to the
36659 (Write_End_Of_Line_Comment): New procedure
36660 (Print): Process comments for nodes N_With_Clause,
36661 N_Package_Declaration, N_String_Type_Declaration,
36662 N_Attribute_Declaration, N_Typed_Variable_Declaration,
36663 N_Variable_Declaration, N_Case_Construction, N_Case_Item.
36664 Process nodes N_Comment.
36666 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
36667 without comments and there are some comments, set the flag
36668 Unkept_Comments to True.
36669 (Scan): If there are comments, set the flag Unkept_Comments to True and
36670 clear the comments.
36671 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
36672 (Next_End_Nodes: New table
36673 (Comment_Zones_Of): New function
36674 (Scan): New procedure; moved from Prj. Accumulate comments in the

36697 * scng.ads, scng.adb (Comment_Is_Token): New Boolean global variable,
36698 defaulted to False.
36699 (Scan): Store position of start of comment. If comments are tokens, set
36700 Comment_Id and set Token to Tok_Comment when scanning a comment.
36701 (Set_Comment_As_Token): New procedure
36703 * sinput-p.adb: Update Copyright notice
36704 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
36705 that no longer exists.
36707 2003-12-08 Javier Miranda <miranda@gnat.com>
36709 * sem_aggr.adb: Add dependence on Exp_Tss package
36710 Correct typo in comment
36711 (Resolve_Aggregate): In case of array aggregates set the estimated
36712 type of the aggregate before calling resolve. This is needed to know
36713 the name of the corresponding IP in case of limited array aggregates.
36714 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
36715 in case of default initialized array components.
36717 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited
36718 types. Required to give support to limited aggregates in generic
36721 2003-12-08 Ed Schonberg <schonberg@gnat.com>

36724 inlined body functions like an instantiation.
36725 (Decimal_Fixed_Point_Declaration): Do not set kind of first subtype
36726 until bounds are analyzed, to diagnose premature use of type.
36728 * sem_util.adb (Wrong_Type): Improve error message when the type of
36729 the expression is used prematurely.
36731 2003-12-08 GNAT Script <nobody@gnat.com>
36733 * Make-lang.in: Makefile automatically updated
36735 2003-12-08 Arnaud Charlet <charlet@act-europe.fr>
36737 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
36738 they are automatically generated by Make-lang.in and cause nothing but
36739 maintenance troubles.
36741 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
36743 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

36752 Update copyright notice when appropriate.
36754 * 52osinte.ads, 5posinte.ads: Define a dummy value for the SA_SIGINFO
36757 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
36758 to ensure that the kernel fills in the interrupted context structure
36759 before calling a signal handler, which is necessary to be able to
36760 unwind past it. Update the copyright notice.
36762 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
36764 * a-elchha.ads: New file.
36766 * a-elchha.adb: New default last chance handler. Contents taken from
36767 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.
36769 * a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine

38218 Remove the test against being in No_Run_Time_Mode before generating a
38219 call to Register_Tag. It is redundant with the test against the
38220 availability of the function Register_Tag.

40406 2002-01-30 Richard Henderson <rth@redhat.com>
40408 * trans.c (tree_transform) [N_Loop_Statement]: Use
40409 expand_exit_loop_top_cond.

40423 rule which was mandated by code generation issues.
40425 * gnat-style.texi (header): Add @dircategory, @direntry.
40426 (title page): Remove date.
40427 (general) Add @./@: where approriate, and two spaces after the
40428 full stop at the end of a sentence. Use @samp markup when
40429 referring concrete lexical entities (keywords, attribute names
40430 etc.), and @syntax for ARM grammar elements. Use @r for English
40431 text in comments. Use @emph for emphasis. Change "if-statements"
40432 etc. to "if statements" (without @samp). Break long lines. Make
40433 casing of section names consistent.
40434 (Identifiers): Use @samp markup for variable names.
40435 (Comments): Use @samp markup for comment characters. Line-end
40436 comments may follow any Ada code, not just statements. Fix
40437 misspelling of "Integer" as "integer".
40438 (Loop statements): Do not use variable name "I", use "J".

40446 function approach did not work well because of a side effect (the
40447 function call could reallocate the table which was being indexed
40448 using its result). Fixes ada/4851.

40815 2001-12-17 Laurent Pautet <pautet@gnat.com>
40818 Fix comment of Shutdown_Socket and Close_Socket. These functions
40819 should not fail silently because if they are called twice, this
40820 probably means that there is a race condition in the user program.
40821 Anyway, this behaviour is consistent with the rest of this unit.
40822 When an error occurs, an exception is raised with the error message
40823 as exception message.

42172 is what this variable will store.
42174 * bcheck.adb: Change reference to chechsum in comments by CRC.
42175 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
42176 rename All_Checksum_Match to All_CRC_Match. Change due to API
42177 renaming since now GNAT does not use a simple checksum but a
42178 CRC using GNAT.CRC32.
42180 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
42181 now and not anymore a simple checksum.
42183 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
42186 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
42189 (Restore_Scan_State): rename Checksum to CRC.
42190 (Save_Scan_State): idem.
42194 (Checksum): rename to CRC.
42195 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
42197 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
42198 GNAT.CRC32). Update copyright notice.
42200 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
42201 GNAT.CRC32). Update copyright notice.
42204 (Accumulate_Checksum): removed.
42205 (Update): new procedure. Add a wide-character into the CRC.

42209 (Load_File): fix initialization of S (change Source_Checksum to
42212 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
42213 Source_CRC in S initialization.

42217 * sinput.ads (Source_Checksum): renamed to Source_CRC.
42218 Update comments for the CRC.
42220 * types.adb (Hex): Use lowercase for the letter part.
42222 * types.ads (Get_Hex_String): Returns the hexadecimal representation
42223 for a word. This is currently used only for CRC. In previous version,
42224 the checksum was using a representation with all letter being
42225 upper-case. With the new implementation (using CRC) we do not remove
42226 the 32th bit of the CRC, so we can have an upper-case starting letter
42227 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
42228 It is ambigous since the CRC was optional and could be followed by
42229 options like EB, EE. So now this routines uses lower-case letter for
42230 the hexadecimal representation. Strange enough only lower case letters
42231 where checked in Scan_ALI (even if this was not a possible case).
42233 * gnatvsn.ads (Library_Version): changed to 3.15a.
42235 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
42238 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version

42245 * ali-util.ads: Redo changes of previous revision to continue to use
42246 the word Checksum. Add 2001 to copyright notice.
42248 * ali.adb: Undo some of previous changes, not needed.
42249 Keep the change for lower case letters in the checksum.
42251 * ali.ads: Undo previous change not needed.
42253 * bcheck.adb: Undo most of previous change, not needed.
42254 But do use Checksums_Match for checksum comparison.
