2050 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
2051 convention from its base type, do not set the type to that of integer,

2118 New local subprogram Is_Valid_Remote_Object_Type, replaces
2119 Is_Recursively_Limited_Private.
2120 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
2121 non-controlling formals (and the return type, even though this is not
2122 explicit in the standard) must support external streaming.

2124 as above for of RAS types and RCI subprograms. (The return type is not

2129 * sem_util.ads, sem_util.adb
2130 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
2131 Is_Remote_Call_Interface to identify RACW types in a stable and
2132 consistent way. We used to rely in this predicate on the privateness of
2133 the designated type and its ancestors, but depending on the currently
2134 visible private parts, this caused false negatives. We now uniformly
2135 rely on checks made at the point where the RACW type is declared.

2149 Add missing escaping of all-caps word 'CPP' in error messages.
2150 (Build_Discriminated_Subtype): Do not inherit representation clauses
2151 from parent type if subtype already carries them, because they are
2152 inherited earlier during derivation and already include those that may
2153 come from a partial view.
2155 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
2156 Check the declarations of a subprogram body for proper deferred

2191 operation of an RACW stub type (these primitives are only executed
2192 through dispatching, never through static calls).
2193 (Collect_Interps): When only one interpretation has been found, set N's
2194 Entity and Etype to that interpretation, otherwise Entity and Etype may
2195 still refer to an interpretation that was ignored by Add_One_Interp,
2196 in which case would end up with being marked as not overloaded but with
2197 an Entity attribute not pointing to its (unique) correct interpretation.
2199 2008-05-20 Ed Schonberg <schonberg@adacore.com>
2202 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

2256 equivalent representation, but has the advantage of allowing
2257 compilation of this file under 64 bits platforms.

6213 reference before the actual is resolved and expanded, to prevent
6214 spurious warnings on formals of enclosing protected operations.
6215 (Analyze_Overloaded_Selected_Component): If type of prefix if
6216 class-wide, use visible components of base type.

6322 clauses for inherited components of a type extension.
6323 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
6324 an overloadable item if it is a pragma that can apply to multiple
6325 overloadable entities (e.g. Inline) because a pragma cannot be on

6456 subprogram body that acts as its own spec may not have a non-private
6457 WITH clause on a private sibling.
6458 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
6459 child unit is a renaming, create an implicit with_clause on that
6460 parent, and not on the unit it renames, to prevent visibility errors

6507 of Related_Interface to Related_Type.
6508 (Record_Type_Declaration): Minor reordering of calls to decorate the

6564 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
6565 Timed_Entry_Call): Analyze the triggering statement as the first step of
6566 the processing. If this is a dispatching select, postpone the analysis
6567 of all select statements until the Expander transforms the select. This

6569 replicated some of the select statements. In case the Expander is
6570 disabled, perform regular analysis.
6571 (Check_Triggering_Statement): New routine.
6572 (Analyze_Requeue): Exclude any interpretations that are not entries when
6573 checking overloaded names in a requeue. Also test type conformance for

7186 Dismukes). After this patch there is no need to perform any
7187 additional management on these nodes in Expand_Interface_Actuals.
7189 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
7190 that handles use of 'Access and 'Unchecked_Access applied to
7191 actuals covering interface types. Such code is now
7192 centralized in Expand_N_Attribute_Reference.
7194 2007-10-15 Ed Schonberg <schonberg@adacore.com>
7196 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
7197 of tagged types whose ultimate ancestor is a CPP type.
7198 (Freeze_Array_Type): For a packed array type, generate an initialization
7199 procedure if the type is public, to handle properly a client that
7200 specifies Normalize_Scalars.
7202 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
7204 * exp_ch9.adb (Actual_Index_Expression): When the expansion occurs
7205 inside a generic body, retrieve the full view of the entry family
7206 discrete subtype if available.
7208 2007-10-15 Thomas Quinot <quinot@adacore.com>
7210 * exp_dist.adb (Add_RACW_Primitive_Declarations_And_Bodies): Do not

7216 returning None, used when there is no platform specific body for
7219 2007-10-15 Bob Duff <duff@adacore.com>
7221 * sem_case.adb, sem_ch13.adb, lib-sort.adb: Replace use of Heap_Sort_A
7222 (passing'Unrestricted_Access of nested subprograms to Sort) with use of
7223 the generic Heap_Sort_G, in order to avoid trampolines.
7225 2007-10-15 Vasiliy Fofanov <fofanov@adacore.com>
7226 Jose Ruiz <ruiz@adacore.com>
7228 * vx_stack_info.c: New file.
7230 * i-forbla-unimplemented.ads: New file.
7232 * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
7233 for unsupported configurations; use it on VMS targets instead of the
7235 (EXTRA_LIBGNAT_SRCS,EXTRA_LIBGNAT_OBJS for VxWorks): Include
7236 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
7237 used by VxWorks targets to have access to task-specific data and be
7238 able to extract the stack boundaries for stack checking.
7239 Use system-vms-ia64.ads on ivms.
7241 * Make-lang.in: Update dependencies.
7243 * sysdep.c (__gnat_get_stack_info): Move to a standalone file
7246 2007-10-15 Vincent Celier <celier@adacore.com>
7248 * snames.adb, snames.ads: Add new standard name runtime_library_dir

7255 the source is unknown.
7257 * prj-ext.adb: Spelling error fix
7259 * prj-nmsc.adb (Check_Ada_Name): Reject any unit that includes an Ada
7260 95 reserved word in its name.
7261 (Process_Project_Level_Array_Attributes): Process new attribute
7262 Runtime_Library_Dir.
7264 * prj-part.adb (Parse_Single_Project): Do not check the name of the
7265 config project against the user project names.
7267 * prj-proc.adb (Expression): In multi-language mode, indexes that do
7268 not include a dot are always case insensitive.
7269 (Process_Declarative_Items): Ditto
7270 (Process_Project_Tree_Phase_1): Set Success to False in case an error is
7273 * prj-util.adb (Value_Of (In_Array)): When Force_Lower_Case_Index is
7274 True, compare both indexes in lower case.

7278 * rtsfind.adb: (Load_RTU): Turn off style checks for Load call
7280 2007-10-15 Gary Dismukes <dismukes@adacore.com>
7282 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
7283 association for an access component, add an association with null as
7284 the expression. Remove testing for array subtypes and the setting in
7285 that case of Ctyp to the array component type, which prevented proper
7286 inclusion of an association for null-initialized arrays. Collapse
7287 condition that tests for array subtypes into just a test of
7288 Is_Partially_Initialized_Type (which already covers arrays anyway).
7290 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
7292 * sem_ch12.adb: Minor code reformatting.
7293 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to
7294 find the parent package which may have been hidden by local

7299 * sem_ch3.adb (Build_Derived_Concurrent_Type): Set the Is_Constrained
7300 flag of derived concurrent types, taking into account the flag setting
7301 on the parent subtype and any new set of discriminants.
7303 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
7305 * sem_ch4.adb: Minor code and comment reformatting.
7306 (Analyze_Allocator): When the designated type of an unconstrained
7307 allocator is a record with unknown discriminants or an array with
7308 unknown range bounds, emit a detailed error message depending on the
7309 compilation mode and whether the designated type is limited.
7311 2007-10-15 Tristan Gingold <gingold@adacore.com>
7313 * system-vms-ia64.ads: New file.

7320 body generated for a function with a controlling result that is a null
7321 extension, discard the generated body in favor of the current explicit
7324 2007-10-15 Ed Schonberg <schonberg@adacore.com>
7326 * sem_disp.adb (Find_Controlling_Arg): Examine the call node before
7327 examining its original form, to handle properly operator calls that
7328 have been rewritten.

7357 * xr_tabls.adb (Add_Reference): Add support for the new 'R' reference
7358 type, for dispatching calls.
7360 2007-10-15 Vincent Celier <celier@adacore.com>
7361 Robert Dewar <dewar@adacore.com>
7363 * gnat_ugn.texi: Add documentation for switches --version and --help
7364 for the GNAT tools gnatbind, gnatlink, gnatmake, gnatchop, gnatname,
7365 gnatxref, gnatfind, gnatls, and gnatclean.

7376 Locally_Removed_Files is obsolescent.
7378 2007-10-15 Thomas Quinot <quinot@adacore.com>
7380 * g-soccon-vms.ads: Fix value of MSG_WAITALL.
7383 Update documentation to note that OpenVMS 8.3 or later must be used
7384 to generate g-soccon-vms.ads.
7386 * atree.adb: Add ??? comment
7388 * exp_util.adb: Minor reformatting.
7389 Add ??? comment in Kill_Dead_Code.
7391 2007-10-15 Robert Dewar <dewar@adacore.com>
7393 * errout.ads: Comment clarification
7395 * exp_ch4.adb (Expand_N_Allocator): Code cleanup.

7404 * osint-b.ads: Minor reformatting
7406 * sem_ch9.adb: Implement -gnatd.I switch
7408 * g-comlin.adb: (Start): Fix handling of empty command line.
7410 * gnatcmd.adb (GNATCmd): Do not put the -rules in the -cargs section,
7411 even when -rules follows the -cargs section.

7429 when compiling for powerpc64-*-linux.
7430 * system-linux-ppc64.ads: New file.
7432 2007-09-27 Eric Botcazou <ebotcazou@adacore.com>
7434 Mapped location support
7435 * back_end.adb (Call_Back_End): Pass information about source
7436 files instead of units to gigi.
7437 * gigi.h (struct File_Info_Type): New.
7438 (gigi): Rename and change type of number_units parameter, change
7439 type of file_info_ptr parameter.
7440 * trans.c (number_files): New global variable.
7441 (gigi): Rename and change type of number_units parameter, change
7442 type of file_info_ptr parameter.
7443 If mapped location support is enabled, create the isomorphic mapping
7444 between source files and line maps.
7445 (Sloc_to_locus): If mapped location support is enabled, translate
7446 source location into mapped location.
7447 (annotate_with_node): Rename into set_expr_location_from_node.
7448 Call set_expr_location instead of annotate_with_locus.
7449 (Pragma_to_gnu): Adjust for above change.

7471 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
7473 * a-calend-vms.adb, a-calend.adb:
7474 Add a section on leap seconds control along with two entities used to
7475 enable and disable leap seconds support. The array Leap_Second_Times is
7476 now constant and contains hard time values pre-generated. Remove
7477 all elaboration code used to populate the table of leap seconds.
7480 Add entity Leap_Seconds_Support to the list of global run-time variables
7481 along with a comment on its usage and values.
7482 (Gen_Adainit_Ada): Add code to generate the declaration and import of
7483 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
7484 or one (enabled) depending on the presence of binder switch "-y".
7485 (Gen_Adainit_C): Add code to generate the declaration of external int
7486 __gl_leap_seconds_support. Set is value to zero (disabled) or one
7487 (enabled) depending on the presence of binder switch "-y".
7489 * init.c: Add __gl_leap_seconds_support to the list of global values
7490 computed by the binder.

7496 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
7497 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
7499 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
7501 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
7502 function which can be called by the debugger to interrupt the tasks of
7503 an Ada application asynchronously, as needed on VxWorks.
7504 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
7506 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
7507 renamed from Stop_All_Tasks. Update comments.
7508 (Stop_All_tasks): New function declaration.
7510 2007-09-26 Olivier Hainque <hainque@adacore.com>
7512 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
7513 #include <utime.h> and #define GCC_RESOURCE_H before
7514 #include <sys/wait.h>.
7515 Add more protections in __gnat_translate_vms.
7517 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
7518 #include <sys/wait.h>.
7520 2007-09-26 Thomas Quinot <quinot@adacore.com>
7521 Sergey Rybin <rybin@adacore.com>
7523 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
7525 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
7528 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
7530 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
7533 * sem_dist.ads: Minor comment fix
7535 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
7537 2007-09-26 Javier Miranda <miranda@adacore.com>
7538 Eric Botcazou <ebotcazou@adacore.com>
7541 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
7542 indirection added to the HT_Link component of the TSD. This is required
7543 to statically allocate the TSD.
7546 Minor reordering of the declarations in the private part. Required to
7547 add a level of indirection to the contents of the TSD component HT_Link.
7548 This is required to statically allocate the TSD.
7550 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
7551 Is_Statically_Allocated set from constant objects.
7552 Do not make exported constants created by the compiler volatile.
7553 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
7556 * trans.c (Identifier_to_gnu): For constants, unshare initializers
7557 before returning them.
7559 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
7560 public part of the package.
7561 (Make_DT): Move HT_Link component out of the TSD record. For this
7562 purpose Make_DT now declares a separate object that stores the
7563 HT_Link value, and initializes the TSD component with the address
7564 of this new object. The addition of this level of indirection is
7565 required to statically allocate the TSD because the TSD cannot
7566 have variable components.
7567 (Expand_Interface_Conversion): Improve the expanded code.
7568 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
7570 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
7571 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
7572 if we are building static dispatch tables then we must not generate
7573 extra code to register the primitive because the dispatch table will
7574 be built at the end of the library package; otherwise we notify that
7575 we cannot build the static dispatch table.
7577 2007-09-26 Robert Dewar <dewar@adacore.com>
7579 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

7594 for thunks associated with interface types.
7596 * einfo.ads: Improve documentatation of Is_Internal
7597 (Is_Thunk): New attribute applicable to subprograms. True for thunks
7598 associated with interface types.
7599 Extensive comment fixes regarding flags that appear in all entities. The
7600 documentation is now consistent for all such flags (there were a number
7601 of errors in the documentation in this regard).
7603 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
7605 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
7606 of these procedures are passed a function call that already has
7607 build-in-place actuals (testing new flag
7608 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
7609 the case where processing continues.
7610 (Expand_Call): If the call is generated from a thunk body then we
7611 propagate the extra actuals associated with the accessibility
7612 level of the access type actuals.
7614 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
7615 of each extra formal of a protected operation to reference the
7616 corresponding extra formal of the subprogram denoted by the
7617 operation's Protected_Body_Subprogram.
7619 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
7620 N_Function_Call nodes.
7622 2007-09-26 Robert Dewar <dewar@adacore.com>
7624 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
7626 * debug.adb: Add d.s flag.
7628 2007-09-26 Gary Dismukes <dismukes@adacore.com>
7630 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
7631 debug variable so that it won't be initialized when pragma
7632 Initialize_Scalars is in effect.
7634 2007-09-26 Gary Dismukes <dismukes@adacore.com>
7636 * freeze.adb (Freeze_Entity): Remove check for preelaborable
7637 initialization of a full view. This is moved to
7638 Analyze_Package_Specification.
7640 * sem_ch7.adb (Analyze_Package_Specification): Add check for
7641 preelaborable initialization of a full view in entity loop.
7642 (Uninstall_Declarations): If entity is a use-visible compilation unit,
7643 its child units are use-visible only if they are visible child units.
7645 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
7646 whether an expression can be used within a type declaration that
7647 requires preelaborable init.
7648 (Check_Components): Replace inline code that does partial checking for
7649 preelaborable default expressions with call to
7650 Is_Preelaborable_Expression.
7651 (Has_Preelaborable_Initialization): In the case of a generic actual
7652 subtype, (that is, Is_Generic_Actual is True), return the result of
7653 applying Has_Preelaborable_Initialization to the generic actual's base
7656 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
7658 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
7659 call to Jan_1_Day _Of_Week to optimize its performance.
7660 (Is_Leap): Move the routine to the scope of Week_In_Year.
7661 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
7662 weekday on which January 1 falls of Year - 1 and Year + 1. This function
7663 avoids calling Time_Of and Split, thus making it more efficent.
7664 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
7666 * g-calend.ads (Week_In_Year): Change comment to reflect new
7669 2007-09-26 Emmanuel Briot <briot@adacore.com>
7671 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
7672 Command_Line): New types
7673 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
7674 support for defining how switches can be grouped on a command line (as
7675 is the case for -gnatw... for GNAT), and how simple switches can be
7676 used as aliases for more complex switches (-gnatwa is same as
7678 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
7679 (Start, Current_*): New subprograms
7680 Added support for parsing an array of strings in addition to the real
7682 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
7683 be moved from the body to the private part of the spec.
7684 (*): All subprograms now have an extra parameter with default value to
7685 specify which parser should be used. For backward compatibility, it
7686 defaults to parsing the command line of the application. They were also
7687 modified to properly handle cases where each of the argument does not
7688 start at index 1 (which is always true for Ada.Command_Line, but not
7689 when processing any Argument_List).
7690 (Free): New subprogram
7691 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
7692 Argument): New subprograms
7693 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
7694 special characters like ':', '=',... are now handled in a single place,
7695 which makes the code more extensible eventually.
7696 (Getopt, Full_Switch): When the switch was returned as part of the
7697 special character '*', make sure it is prepended by the switch character
7698 ('-' in general), so that the application knows whether "foo" or "-foo"
7699 was specified on the command line.
7701 2007-09-26 Florian Villoing <villoing@adacore.com>
7703 * g-dirope.adb (Remove_Dir): In case we are removing directories
7704 recursively, make sure that if an exception is raised during the
7705 processing, the current working directory is reset to its initial
7706 value before propagating the exception.

8107 procedures have been processed, because the IP call needs to undergo
8108 shared passive variable reference expansion, which requires these
8109 procedures to be available (and elaborated).

8120 and the value of the discriminant is the discriminant of the enclosing
8121 type, retrieve its value from the aggregate itself, where it must have
8124 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
8125 to remove other spurious ambiguities on arithmetic operations involving
8126 literals and addresses, on systems where Address is a visible integer
8127 type, when the operator is called in functional notation.
8128 (Try_Primitive_Operation): Within an instance, a call in prefixed form
8129 is legal when the types match, even if the operation is currently

8134 * sem_ch12.adb (Build_Local_Package): A formal package with no
8135 associations is legal if all formals have defaults. It is not

8254 (Write_Entity_Flags): Write the status of flag Is_Raised.
8255 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
8256 spurious ambiguities when integer literals appear in the context of an
8257 address type that is a visible integer type.

8277 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
8278 library-level package renaming, pass the declaration associated with
8279 the renaming's special debug variable to Qualify_Entity_Names to ensure

8282 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
8283 occurring in the list of entities to qualify, and do not attempt to
8284 traverse an entity list in that case. Variables associated with
8285 ` library-level package renamings can now occur in the table.
8287 * exp_dbug.ads: Revise documentation of the encoding for renaming
8290 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

8311 avoid very deep recursion in the front end, which was causing stack
8314 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
8315 string, and the right operand is a string literal (the case of "" &
8316 "..."), optimize by avoiding copying the right operand -- just use the
8317 value of the right operand directly.
8319 * stringt.adb (Store_String_Chars): Optimize by growing the
8320 String_Chars table all at once, rather than appending characters one by
8322 (Write_String_Table_Entry): If the string to be printed is very long,
8323 just print the first few characters, followed by the length. Otherwise,
8324 doing "pn(n)" in the debugger can take an extremely long time.
8326 * sem_prag.adb (Process_Interface_Name): Replace loop doing
8327 Store_String_Char with Store_String_Chars.

8346 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
8347 flag, for effiency. It is called when analyzing arithmetic operators
8348 and also for actuals in calls that are universal_integers. The flag is
8349 set for the predefined type address, and for any type or subtype
8352 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
8353 Universal_Integer, when the formal is a descendent of address and the
8354 call appears in user code.

8421 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
8422 associated with Standard_Debug_Renaming_Type, to be used as the type of
8423 the special variables whose names provide debugger encodings for
8424 renaming declarations.
8426 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.

8434 (Debug_Renaming_Declaration): Replace creation of an enumeration type
8435 and literal with creation of a variable of type
8436 Standard_Debug_Renaming_Type whose name encodes both the renamed object
8437 and the entity of the renaming declaration.
8438 (Qualify_Entity_Name): Add the delayed qualification of the entity name
8439 part of the name of a variable that has a Debug_Renaming_Link.

8446 Ed Schonberg <schonberg@adacore.com>
8447 Javier Miranda <miranda@adacore.com>
8449 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
8450 ancestor part given by an aggregate to test for an unchecked conversion,
8451 since this can occur in some cases when the ancestor part is a function
8452 call, and we don't want to fall into the recursive call to this
8453 procedure in that case.
8455 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
8456 stream attributes on limited types to account for user-specified
8457 attributes as well as whether Input (resp. Output) becomes available
8458 due to Read (resp. Write) being available for the type. Change Boolean
8459 variable to the more accurate name
8460 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
8461 double-"not" predicate at beginning of return statement to more
8462 understandable form.
8464 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
8465 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
8466 in a block statement and use that as the first statement of the
8467 expanded return rather than incorrectly using the handled sequence as
8468 the first statement.
8470 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
8471 operation, generate an explicit freeze node for it rather than
8472 generating extra formals, to ensure that gigi has the proper order of
8473 elaboration for anonymous subtypes in the signature of the subprograms.
8474 (Build_In_Place_Formal): Move assertion to beginning of loop.
8475 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
8476 applied to a function call (occurs for some cases of 'Input).
8477 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
8478 applied to a function call (occurs for some cases of 'Input).
8480 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
8481 2005, generate an extended return statement enclosing the result object
8484 * freeze.adb (Freeze_Record_Type): Extend the current management of
8485 components that are access type with an allocator as default value: add
8486 missing support to the use of qualified expressions of the
8487 allocator (which also cause freezing of the designated type!)
8488 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
8489 dispatching operation, since extra formals may be needed by calls to
8490 build-in-place functions (such as stream 'Input).
8492 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
8493 formals for 'Constrained and accessibility level in the case of a
8494 predefined dispatching operation.
8496 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
8497 point, no need to find the parent node.
8499 2007-08-16 Javier Miranda <miranda@adacore.com>
8501 * exp_attr.adb (Attribute_Priority): Add missing support for entries
8504 2007-08-16 Javier Miranda <miranda@adacore.com>
8506 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
8507 is not really required and can introduce regression with the debugger.
8508 The original problem is fixed with the patch written for checks.adb.
8510 2007-08-16 Thomas Quinot <quinot@adacore.com>
8512 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

8522 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
8523 parameter Including_Non_Switch, defaulted to True. When
8524 Including_Non_Switch is False, options that are not switches and
8525 appear as relative path are not converted to absolute paths.

8541 (Install_Limited_Withed_Unit): Do not install the limited view of
8542 package P if P is reachable through an ancestor chain from package C
8543 and C also has a with clause for P in its body.
8544 (Has_Limited_With_Clause): New routine.
8545 (Has_With_Clause): New routine.
8547 2007-08-16 Ed Schonberg <schonberg@adacore.com>
8549 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
8550 generic for an enclosing instance is a global reference, even though
8551 its scope is the enclosing instance.

8577 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
8578 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
8579 the statement which is being resolved comes from a predefined library
8580 unit, all non-predefined library interpretations are skipped.
8581 (Resolve_Op_Concat): If string concatenation was folded in the parser,
8582 but the "&" is user defined, give an error, because the folding would
8585 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
8586 the parser has folded a long sequence of concatenations of string
8589 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
8590 and "JMP_BUF" variables as artificial.
8591 (N_String_Literal): Do not use alloca for very long string literals. Use

8637 Ed Schonberg <schonberg@adacore.com>
8639 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
8640 Suppress unmodified in-out parameter warning in some cases
8641 This patch is a also fairly significant change to the way suppressible
8644 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
8645 needed for access to concurrent record types generated by the expander.
8646 (Generate_Range_Check): When generating a temporary to capture the
8647 value of a conversion that requires a range check, set the type of the
8648 temporary before rewriting the node, so that the type is always
8649 properly placed for back-end use.
8650 (Apply_Float_Conversion_Check): Handle case where the conversion is
8652 (Get_Discriminal): Code reformatting. Climb the scope stack looking
8653 for a protected type in order to examine its discriminants.

8662 tests optimized out.
8664 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
8665 (Get_Allocator_Final_List): For the case of an anonymous access type
8666 that has a specified Associated_Final_Chain, do not go up to the
8668 (Expand_N_Type_Conversion): Test for the case of renamings of access
8669 parameters when deciding whether to apply a run-time accessibility
8671 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
8672 aggregate code before allocator, and ahead of declaration for
8673 temporary, to prevent access before elaboration when the allocator is
8674 an actual for an access parameter.
8675 (Expand_N_Type_Conversion): On an access type conversion involving an
8676 access parameter, do not apply an accessibility check when the
8677 operand's original node was an attribute other than 'Access. We now
8678 create access conversions for the expansion of 'Unchecked_Access and
8679 'Unrestricted_Access in certain cases and clearly accessibility should
8680 not be checked for those.
8682 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
8683 includes a type conversion of a packed component that has been expanded,
8684 recover the original expression for the object, and use this expression
8685 in the post-call assignment statement, so that the assignment is made
8686 to the object and not to a back-end temporary.
8687 (Freeze_Subprogram): In case of primitives of tagged types not defined
8688 at the library level force generation of code to register the primitive
8689 in the dispatch table. In addition some code reorganization has been
8690 done to leave the implementation clear.
8691 (Expand_Call): When expanding an inherited implicit conversion,
8692 preserve the type of the inherited function after the intrinsic
8693 operation has been expanded.
8695 * exp_ch2.ads, exp_ch2.adb
8696 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
8697 of an entry formal appearing in an assignment statement does not assign
8699 (Expand_Current_Value): Instead of calling a routine to determine
8700 whether the prefix of an attribute reference should be optimized or
8701 not, prevent the optimization of such prefixes all together.
8703 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
8704 component whose prefix is known to be of an access type is an implicit
8705 dereference and does not assign to the prefix.
8707 2007-08-14 Ed Schonberg <schonberg@adacore.com>
8708 Robert Dewar <dewar@adacore.com>
8710 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
8711 itype is visited, make an entry into table to link associated node and
8713 Add comments and correct harmless error in Build_NCT_Hash_Tables
8714 (Array_Aggr_Subtype): Associate each itype created for an index type to
8715 the corresponding range construct, and not to the aggregate itself. to
8716 maintain a one-to-one correspondence between itype and its associated
8717 node, to prevent errors when complex expression is copied.
8718 Fix mishandling of multiple levels of parens
8720 * sem_aggr.adb: Create a limited view of an incomplete type, to make
8721 treatment of limited views uniform for all visible declarations in a
8722 limited_withed package.
8723 (New_Copy_Tree): If hash table is being used and itype is visited,
8724 make an entry into table to link associated node and new itype.
8725 (Resolve_Record_Aggregate): Do not add an others box association for a
8726 discriminated record component that has only discriminants, when there
8727 is a box association for the component itself.
8729 * par-ch4.adb: Fix mishandling of multiple levels of parens

8767 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
8768 to make treatment of limited views uniform for all visible declarations
8769 in a limited_withed package.
8770 Improve warnings for in out parameters
8771 (Set_Related_Interaface/Related_Interface): Allow the use of this
8772 attribute with constants.
8773 (Write_Field26_Name): Handle attribute Related_Interface in constants.
8774 Warn on duplicate pragma Preelaborable_Initialialization
8776 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
8777 generation of a freezing node to ensure proper management of null
8778 excluding access types in the backend.
8779 (Create_Extra_Formals): Test base type of the formal when checking for
8780 the need to add an extra accessibility-level formal. Pass the entity E
8781 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
8782 originally being done in a couple of cases), to ensure that the
8783 Extra_Formals list gets set on the entity E when the first entity is
8785 (Conforming_Types): Add missing calls to Base_Type to the code that
8786 handles anonymous access types. This is required to handle the
8787 general case because Process_Formals builds internal subtype entities
8788 to handle null-excluding access types.
8789 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
8790 functions that need it, even when not marked Requires_Overriding.
8791 Improve warnings for in out parameters
8792 (Analyze_Function_Return): Warn for disallowed null return
8793 Warn on return from procedure with unset out parameter
8794 Ensure consistent use of # in error messages
8795 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
8796 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
8797 the implicit conversion of the expression done for anonymous access
8798 types. This is required to generate the code of the null excluding
8799 check (if required).
8801 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
8802 A formal parameter is never publicly referenceable outside of its body.
8803 (Check_References): For an unreferenced formal parameter in an accept
8804 statement, use the same warning circuitry as for subprogram formal
8806 (Warn_On_Unreferenced_Entity): New subprogram, taken from
8807 Output_Unreferenced_Messages, containing the part of that routine that
8808 is now reused for entry formals as described above.
8809 (Goto_Spec_Entity): New function
8810 (Check_References): Do not give IN OUT warning for dispatching operation
8811 Improve warnings for in out parameters
8812 (Test_Ref): Check that the entity is not undefinite before calling
8813 Scope_Within, in order to avoid infinite loops.
8814 Warn on return from procedure with unset out parameter
8815 Improved warnings for unused variables

8818 Javier Miranda <miranda@adacore.com>
8819 Gary Dismukes <dismukes@adacore.com>
8821 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
8822 (Expand_N_Attribute_Reference): Further unify the handling of the
8823 three forms of access attributes, using common code now for all three
8824 cases. Add a test for the case of applying an access attribute to
8825 an explicit dereference when the context is an access-to-interface
8826 type. In that case we need to apply the conversion to the prefix
8827 of the explicit dereference rather than the prefix of the attribute.
8828 (Attribute_Version, UET_Address): Set entity as internal to ensure
8829 proper dg output of implicit importation.
8830 (Expand_Access_To_Type): Removed.
8831 (Expand_N_Attribute_Reference): Merge the code from the three cases
8832 of access attributes, since the processing is largely identical for
8833 these cases. The substantive fix here is to process the case of a
8834 type name prefix (current instance case) before handling the case
8835 of interface prefixes.

8839 Javier Miranda <miranda@adacore.com>
8840 Robert Dewar <dewar@adacore.com>
8842 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
8843 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
8844 type that is an anonymous access to controlled object, establish
8845 an associated finalization chain to avoid corrupting the global
8846 finalization list when a dynamically allocated object designated
8847 by such a component is deallocated.
8848 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
8849 functions that need it, even when not marked Requires_Overriding.
8850 (Initialize_Tag): Replace call to has_discriminants by call to
8851 Is_Variable_Size_Record in the circuitry that handles the
8852 initialization of secondary tags.
8853 (Is_Variable_Size_Record): New implementation.
8854 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
8855 Suppress_Initialization pragma for a derived type.
8856 (Is_Variable_Size_Record): New subprogram.
8857 (Build_Offset_To_Top_Functions): New implementation that simplifies the
8858 initial version of this routine and also fixes problems causing
8859 incomplete initialization of the table of interfaces.
8860 (Build_Init_Procedure): Improve the generation of code to initialize the
8861 the tag components of secondary dispatch tables.
8862 (Init_Secondary_Tags): New implementation that simplifies the previous
8863 version of this routine.
8864 (Make_DT): Add parameter to indicate when type has been frozen by an
8865 object declaration, for diagnostic purposes.
8866 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
8867 diagnose attemps to freeze a subprogram when some untagged type of its
8868 profile is a private type whose full view has not been analyzed yet.
8869 (Freeze_Array_Type): Generate init proc for packed array if either
8870 Initialize or Normalize_Scalars is set.
8871 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
8872 constructing the new profile, copy the null_exclusion indicator for each
8873 parameter, to ensure full conformance of the new body with the spec.
8875 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
8876 Create wrappers for constructor functions that need it, even when not
8877 marked Requires_Overriding.
8878 (Covers): Handle properly designated types of anonymous access types,
8879 whose non-limited views are themselves incomplete types.
8880 (Add_Entry): Use an entity to store the abstract operation which hides
8882 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
8883 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
8884 initialization aggregate.
8885 (Function_Interp_May_Be_Hidden): Rename to
8886 Function_Interp_Has_Abstract_Op.
8887 (Has_Compatible_Type): Remove machinery that skips interpretations if
8888 they are labeled as potentially hidden by an abstract operator.
8889 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
8890 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
8891 (Write_Overloads): Output the abstract operator if present.
8892 (Add_Entry): Before inserting a new entry into the interpretation table
8893 for a node, determine whether the entry will be disabled by an abstract
8895 (Binary_Op_Interp_May_Be_Hidden): New routine.
8896 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
8898 (Function_Interp_May_Be_Hidden): New routine.
8899 (Has_Compatible_Type): Do not consider interpretations hidden by
8900 abstract operators when trying to determine whether two types are
8902 (Has_Hidden_Interp): New routine.
8903 (Set_May_Be_Hidden_Interp): New routine.
8904 (Write_Overloads): Write the status of flag May_Be_Hidden.

8907 Javier Miranda <miranda@adacore.com>
8909 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
8910 types declared in the declarative part of a nested package body or in
8911 the proper body of a stub.
8912 (Set_All_DT_Position): Add missing check to avoid wrong assignation
8913 of the same dispatch table slot to renamed primitives.
8914 (Make_Select_Specific_Data_Table): Handle private types.
8915 (Tagged_Kind): Handle private types.
8916 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
8917 output of implicit importation and exportation.
8918 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
8919 first formal of the thunk is always associated with the controlling
8920 type. In addition perform the following code cleanup: remove formal
8921 Thunk_Alias which is no longer required, cleanup evaluation of the
8922 the controlling type, and update the documentation.
8923 Replace occurrence of Default_Prim_Op_Count by
8924 Max_Predef_Prims. Addition of compile-time check to verify
8925 that the value of Max_Predef_Prims is correct.
8926 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
8927 (Make_DT): Add parameter to indicate when type has been frozen by an
8928 object declaration, for diagnostic purposes.
8929 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
8930 construction of statically allocated dispatch tables.
8931 (Make_DT): In case of library-level tagged types export the declaration
8932 of the primary tag. Remove generation of tags (now done by Make_Tags).
8933 Additional modifications to handle non-static generation of dispatch
8934 tables. Take care of building tables for asynchronous interface types
8935 (Make_Tags): New subprogram that generates the entities associated with
8936 the primary and secondary tags of Typ and fills the contents of Access_
8937 Disp_Table. In case of library-level tagged types imports the forward
8938 declaration of the primary tag that will be declared later by Make_DT.
8939 (Expand_Interface_Conversion): In case of access types to interfaces
8940 replace an itype declaration by an explicit type declaration to avoid
8941 problems associated with the scope of such itype in transient blocks.
8943 2007-08-14 Robert Dewar <dewar@adacore.com>
8944 Ed Schonberg <schonberg@adacore.com>
8945 Javier Miranda <miranda@adacore.com>
8947 * exp_util.ads, exp_util.adb:
8948 This patch replaces a number of occurrences of explicit tests for N_Null
8949 with calls to Known_Null. This improves tracking of null values, since
8950 Known_Null also catches null constants, and variables currently known to
8951 be null, so we get better tracking.
8952 (Ensure_Defined): create an itype reference only in the scope of the
8954 (Side_Effect_Free): A selected component of an access type that
8955 denotes a component with a rep clause must be treated as not
8956 side-effect free, because if it is part of a linked structure its
8957 value may be affected by a renaming.
8958 (Expand_Subtype_From_Expr): For limited objects initialized with build
8959 in place function calls, do nothing; otherwise we prematurely introduce
8960 an N_Reference node in the expression initializing the object, which
8961 breaks the circuitry that detects and adds the additional arguments to
8962 the called function. Bug found working in the new patch for statically
8963 allocated dispatch tables.
8964 (Is_Library_Level_Tagged_Type): New subprogram.
8965 (Remove_Side_Effects): If the expression of an elementary type is an
8966 operator treat as a function call.
8967 (Make_Literal_Range): If the index type of the array is not integer, use
8968 attributes properly to compute the constraint on the resulting aggregate
8971 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
8972 class-wide type whose base type is an incomplete private type, leave
8973 class-wide type unfrozen so that freeze nodes can be generated
8974 properly at a later point.
8975 (Freeze_Entity, array case): Handle case of pragma Pack and component
8976 size attributre clause for same array.

9031 Allow all valid declarations in configuration project files
9032 (Search_Directories): Detect subunits that are specified with an
9033 attribute Body in package Naming. Do not replace a source/unit in the
9034 same project when the order of the source dirs are known. Detect
9035 duplicate sources/units in the same project when the order of the
9036 source dirs are not known.
9037 (Check_Ada_Name): Allow all identifiers that are not reserved words
9039 Major update of the Project Manager and of the project aware tools,
9040 including gprmake, so that the same sources in the GNAT repository
9041 can be used by gprbuild.

9043 directory of non extending project to nil.
9044 Change type of path name variables to be Path_Name_Type
9045 (Locate_Directory): Make sure that on Windows '/' is converted to '\',
9046 otherwise creating missing directories will fail.

9625 operations in Derive_Subprograms.
9626 (Collect_Previous_Instances): new procedure within of
9627 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
9628 unit being loaded, to ensure that the generation of global symbols is

9630 (Is_Tagged_Ancestor): New function testing the ancestor relation that
9631 takes progenitor types into account.
9632 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
9633 traversing over the primitives of the formal and actual types to locate
9634 any abstract subprograms of the actual type that correspond to a
9635 nonabstract subprogram of the formal type's ancestor type(s), and issue
9636 an error if such is found.
9637 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,

9653 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
9654 type, the candidate operations are found in the scope of declaration of
9655 the type, because the type has no primitive subprograms.
9656 (Analyze_Selected_Component): If prefix is class-wide, and root type is
9657 a private extension, only examine visible components before trying to
9658 analyze as a prefixed call.
9659 Change Entity_List to Type_To_Use, for better readability.

9673 purpose of enforcing E.2.2(8) only if it is not available at any place.
9674 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
9675 when checking the legality of an extension aggregate in a preelaborable
9676 package. Treat the literal null as a valid default expression in a
9677 component declaration for a type with preelaborable initialization.
9678 A limited interface is a legal progenitor for the designated type of a
9679 remote access to class-wide type.

9711 do not consider those that are hidden by abstract operators.
9712 (Resolve_Actuals): When verifying that an access to class-wide object
9713 is an actual for a controlling formal, ignore anonymous access to
9714 subprograms whose return type is an access to class_wide type.
9715 (Resolve_Slice): If the prefix of the slice is a selected component
9716 whose type depends on discriminants, build its actual subtype before
9717 applying range checks on the bounds of the slice.
9718 (Valid_Conversion): In an instance or inlined body, compare root types,
9719 to prevent anomalies between private and public views.

10895 applicable to types that have the With_Type flag set. Returns the
10896 non-limited view of the type, if available, otherwise the type itself.
10897 For class-wide types, there is no direct link in the tree, so we have
10898 to retrieve the class-wide type of the non-limited view of the Etype.
10899 New attributes Static_Initialization and Static_Elaboration_Desired.
10900 Remove the pragma Thread_Body, and the associated flag
10901 Is_Thread_Body in entities, and all related code.
10902 (Suppress_Value_Tracking_On_Call): New flag
10903 E_Exception has Esize and Alignment fields
10904 (Universal_Aliasing): New function.
10905 (Set_Universal_Aliasing): New procedure.
10906 (Write_Entity_Flags): Deal with Universal_Aliasing flag.
10907 (Check_Nested_Access): New procedure.
10908 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
10909 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
10910 (Related_Interface): New attribute. Present in dispatch table pointer
10911 components of records. Set to point to the entity of the corresponding
10913 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
10914 (Original_Access_Type): Remove, not needed.
10915 (Root_Type): Handle properly subtypes of class-wide-types.
10918 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
10919 class-wide types visible through limited-with clauses.
10920 (Try_Primitive_Operation): When examining all primitive operations of a
10921 tagged type, do not consider subprograms labeled as hidden unless they
10922 belong to a private generic type with a tagged parent.
10923 (Try_Object_Operation): Extensive rewriting, to handle properly various
10924 overloading cases, when several ancestors may have class-wide operations
10925 that are possible candidates, and when the overloaded functions return
10926 array types and have defaulted parameters so that the call may be
10927 interpreted as an indexing.
10928 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
10929 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
10930 successive actuals before analyzing the call itself.
10931 (Try_Primitive_Operation): A primitive operation is compatible with the
10932 prefix if the prefix has a synchronized type and the type of the formal
10933 is its corresponding record, as can be the case when the primitive
10934 operation is declared outside of the body of the type.
10935 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
10936 perform homonym traversal, looking for class-wide operation matches
10937 (formerly done in statements of Try_Class_Wide_Operation). Matches on
10938 access parameters are now restricted to anonymous access types.
10939 (Mark_Allocator): An allocator with a discriminant association parent is
10941 (Try_One_Prefix_Interpretation): If the type of the object is
10942 incomplete, as can be happen when it is a limited view obtained through
10943 a limited_with_clause, the selected component is not part of a prefixed
10945 (Complete_Object_Operation): Diagnose properly an object that is not
10946 aliased when the corresponding controlling formal is an access
10948 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
10949 ambiguous calls in prefixed notation, where two primitives differ only
10950 in that the controlling argument of one is an access parameter.
10952 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
10953 whether a function that returns an unconstrained type can be inlined.
10954 (Process_Formals): Diagnose properly the illegal use of an incomplete
10955 type in the profile of an access_to_subprogram declaration.
10956 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
10957 operations are attached to the corresponding record.
10958 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
10959 When processing a primitive of a concurrent type which implements an
10960 interface change the type of all controlling formals to that of the
10961 corresponding record type.
10962 (Check_Synchronized_Overriding): Relax the conditional logic when trying
10963 to determine the tagged type to which a primitive belongs.
10964 (Check_Conventions): Capture condition to ignore a primitive operation
10965 (which is shared between the loop in Check_Conventions and the one in
10966 Check_Convention) in a new local function Skip_Check.
10967 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
10968 confusion with Check_Conventions' own Prim_Op local variable.
10969 (Create_Extra_Formals): Test for a tagged result type rather than a
10970 controlling result when determining whether to add a BIP_Alloc_Form
10971 formal and a BIP_Final_List formal to the function.
10972 (Check_Conformance); For parameters that are anonymous access types,
10973 subtype conformance requires that the not null and the constant
10974 indicators must match
10975 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
10976 to retrieve the appropriate type when processing a concurrent type
10977 declared within a generic. Minor comment reformatting. Change invocation
10978 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
10980 (Analyze_Subprogram_Body): If the return type of a function is an
10981 anonymous access to the limited view of a class-wide type, and the
10982 non-limited view of the type is available, update the type of the
10983 function so that code can be generated.
10984 (Process_Formals): In case of access-subtype itype whose designated
10985 type is also an itype (situation that happens now with access to
10986 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
10987 attribute to avoid backend problems.
10988 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
10989 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
10990 anonymous types' designated types are same before testing
10991 Subtypes_Statically_Match.
10992 (Create_Extra_Formals): Test for a named access parameter that is a
10993 controlling formal as an additional condition for adding an
10994 accessibility level formal. This can occur in the subp type created for
10995 dispatching calls in Expand_Dispatching_Call, and allows calling
10996 Create_Extra_Formals from that procedure rather than special-casing the
10997 extra formals there.
10998 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
10999 when the function has a controlling result.
11000 (Check_Returns): Add much more knowledge of the optimization of local
11001 raise statements to gotos, to retain proper warnings in this case.
11002 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
11003 nodes when looking for last statement.
11005 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
11006 class-wide types visible through limited with clauses.
11007 (Add_One_Interp): If the operands are anonymous access types, the
11008 predefined operator on universal_access is immediately visibles
11009 (Find_Unique_Type): Handle anonymous access to subprogram types just as
11010 other anonymous access types.
11011 (Disambiguate): Take into account CIL convention.
11012 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
11014 2007-06-06 Robert Dewar <dewar@adacore.com>
11016 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
11017 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
11018 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
11019 Fix lower bound of tables.
11022 * nlists.adb: Ditto.
11023 (Prev_Node, Next_Node): Change index type to Int so that it properly
11024 covers the range First_Node_Id - 1 up.
11026 2007-06-06 Javier Miranda <miranda@adacore.com>
11027 Ed Schonberg <schonberg@adacore.com>
11028 Bob Duff <duff@adacore.com>
11029 Hristian Kirtchev <kirtchev@adacore.com>
11031 * exp_aggr.ads, exp_aggr.adb:
11032 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
11033 in extension aggregates.
11034 (Flatten): Other conditions being met, an aggregate is static if the
11035 low bound given by component associations is different from the low
11036 bound of the base index type.
11037 (Packed_Array_Aggregate_Handled): If the component type is itself a
11038 packed array or record, the front-end must expand into assignments.
11039 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
11040 Init_Pr, instead of Ancestor_Is_Expression.
11041 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
11042 coextension chain root, either generate a list controller or use the
11043 already existing one.
11044 (Static_Array_Aggregate): New procedure to construct a positional
11045 aggregate that can be handled by the backend, when all bounds and
11046 components are compile-time known constants.
11047 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
11048 types covering interface types into assignments.
11049 (Replace_Type): move to Build_Record_Aggr_Code.
11050 (Expand_Record_Aggr_Code): if the target of the aggregate is an
11051 interface type, convert to the definite type of the aggregate itself,
11052 so that needed components are visible.
11053 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
11054 components and the context is an extended return statement do not
11055 create a transient block for it, to prevent premature finalization
11056 before the return is executed.
11057 (Gen_Assign): Do not generate a call to deep adjust routine if the
11058 component type is itself an array of controlled (sub)-components
11059 initialized with an inner aggregate.
11060 (Component_Check): New name for Static_Check. This name is now more
11061 appropriate, and documentation is added which was missing.
11062 (Component_Check): Add test for bit aligned component value
11063 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
11064 Tagged_Comps, name is more appropriate given added function below.
11065 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
11067 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
11068 Javier Miranda <miranda@adacore.com>
11069 Robert Dewar <dewar@adacore.com>
11071 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
11072 Terminated: Add unchecked type conversion from System.Address to
11073 System.Tasking.Task_Id when calling the predefined primitive
11075 Disable new Ada 05 accessibility check for JVM.NET targets, which
11076 cannot be implemented in a practical way.
11077 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
11078 the sources always references the tag of the actual object. Therefore,
11079 if 'Tag is applied in the sources to class-wide interface objects we
11080 generate code that displaces "this" to reference the base of the object.
11081 (Expand_N_Attribute_Reference, case Size): Return specified size if
11082 known to front end.
11083 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
11084 has code that displaces the pointer of the object to manage interface
11085 types. However this code must not be executed when the prefix is a
11086 subprogram. This bug caused the wrong expansion of the internally
11087 generated assignment that fills the dispatch table when the primitive
11088 is a function returning a class-wide interface type.
11089 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
11090 Set_Attribute_Name for Name_Unaligned_Valid.
11092 2007-06-06 Ed Schonberg <schonberg@adacore.com>
11093 Gary Dismukes <dismukes@adacore.com>
11095 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
11096 If the initialization is the equivalent aggregate of the initialization
11097 procedure of the type, do not remove it.
11098 (Expand_N_Attribute_Definition_Clause): Exclude access variables
11099 initialized to null from having their expression reset to empty and
11100 note this exception in the comment.
11102 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
11103 Robert Dewar <dewar@adacore.com>
11104 Ed Schonberg <schonberg@adacore.com>
11105 Gary Dismukes <dismukes@adacore.com>
11107 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
11108 Add "with" and "use" clauses for Sem_Attr.
11109 (Expand_Current_Value): Do not replace occurences of attribute
11110 references where the prefix must be a simple name.
11112 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
11113 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
11114 Attribute_Requires_Simple_Name_Prefix.
11115 (Name_Modifies_Prefix): Body of new function.
11116 (Requires_Simple_Name_Prefix): Body of new function.
11117 (Resolve_Attribute, case Access): Improve error message for case of
11118 mismatched conventions.
11119 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
11121 (Analyze_Attribute, case 'Access): If the type of the prefix is a
11122 constrained subtype for a nominal unconstrained type, use its base type
11123 to check for conformance with the context.
11124 (Resolve_Attribute): Remove test of the access type being associated
11125 with a return statement from condition for performing accessibility
11126 checks on access attributes, since this case is now captured by
11127 Is_Local_Anonymous_Access.
11128 (Analyze_Access_Attribute): Set Address_Taken on entity
11129 (Analyze_Attribute, case Address): Set Address_Taken on entity
11130 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
11131 validating an access attribute whose prefix is a current instance.
11132 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
11133 applied to dispatching operations, if freezing is required then we set
11134 the attribute Has_Delayed_Freeze in the prefix's entity.
11135 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
11136 current scope if access of local subprogram taken
11137 (Analyze_Access_Attribute): Check legality of self-reference even if the
11138 expression comes from source, as when a single component association in
11139 an aggregate has a box association.
11140 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
11141 the prefix if it is a protected operation and the attribute is
11142 Unrestricted_Access.
11143 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
11144 reference to the base type of the context, to force a constraint check
11145 when the context is an access subtype with an explicit constraint.
11146 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
11147 node is rewritten as an interface conversion. leave unanalyzed after
11148 resolution, to ensure that type checking against the context will take

11152 Javier Miranda <miranda@adacore.com>
11153 Robert Dewar <dewar@adacore.com>
11155 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
11156 wrapper when the full view of the controlling type of an inherited
11157 function that dispatches on result implements interfaces.
11158 (Expand_N_Object_Declaration): In cases where the type of the
11159 declaration is anonymous access, create finalization list for it.
11160 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
11161 if the object has no explicit initialization, to match description of
11162 functionality of pragam Persistent_BSS.
11163 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
11164 new function to build static aggregates, to replace initialization call
11165 when static initialization is desired.
11166 (Freeze_Type): Generate a list controller for an access type whenever
11167 its designated type has controlled anonymous access discriminants.
11168 (Build_Equivalent_Aggregate): New procedure to compute a static
11169 aggregate to be used as default initialization for composite types,
11170 instead of a generating a call to the initialization procedure for the
11172 (Build_Initialization_Call): When available, replace a call to the
11173 initialization procedure with a copy of the equivalent static aggregate
11175 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
11176 declarations for objects of a class-wide interface type, rather than
11177 just identifiers, to prevent visibility problems.
11178 (Expand_N_Object_Declaration): When expanding the declaration for an
11179 object of a class-wide interface type, preserve the homonym chain of
11180 the original entity before exchanging it with that of the generated
11181 renaming declaration.
11182 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
11183 active, because there is no way to handle the exception.
11184 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
11185 to do a minimum decoration of the Access_Disp_Table list.
11186 (Expand_Record_Controller): Avoid the addition of the controller between
11187 the component containing the tag of a secondary dispatch table and its
11188 adjacent component that stores the offset to the base of the object.
11189 This latter component is only generated when the parent type has
11190 discriminants ---documented in Add_Interface_Tag_Components).
11191 (Apply_Array_Size_Check): Removed, no longer needed.
11192 (Expand_N_Full_Type_Declaration): If the type has anonymous access
11193 components, create a Master_Entity for it only if it contains tasks.
11194 (Build_Init_Procedure): Suppress the tag assignment compiling under
11196 (Freeze_Record_Type): Remove code associated with creation of dispatch
11198 (Init_Secondary_Tags): Update type of actuals when generating calls to
11199 Ada.Tags.Set_Offset_To_Top
11200 (Stream_Operation_OK): Disable use of streams compiling under no
11202 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
11203 if Has_Init_Expression set.
11204 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
11205 Register_Primitive, which provides the same functionality.
11206 (Requires_Init_Proc): Return false in case of interface types.
11207 (Add_Secondary_Tables): Use the new attribute Related_Interface to
11209 (Predefined_Primitive_Freeze): Do not assume that an internal entity
11210 is always associated with a predefined primitive because the internal
11211 entities associated with interface types are not predefined primitives.
11212 Therefore, the call to Is_Internal is replaced by a call to the
11213 function Is_Predefined_Dispatching_Operation.
11214 (Make_Eq_If): When generating the list of comparisons for the
11215 components of a given variant, omit the controller component that is
11216 present if the variant has controlled components.
11218 2007-06-06 Javier Miranda <miranda@adacore.com>
11219 Hristian Kirtchev <kirtchev@adacore.com>
11220 Bob Duff <duff@adacore.com>
11222 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
11223 handle the creation of finalization lists and calls for nested
11224 coextensions when the root of the chains is part of a return statement.
11225 (Inside_A_Return_Statement): New function inside Complete_Coextension_
11227 (Expand_Record_Equality): Skip components that are interface types.
11228 (Displace_Allocator_Pointer): Add missing support for interface subtypes
11229 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
11230 with Rewrite_Coextension. Change the condition for detecting coextension
11232 (Is_Local_Access_Discriminant): Removed.
11233 (Rewrite_Coextension): New routine which rewrites a static coextension
11234 as a temporary and uses its unrestricted access in the construction of
11236 (Complete_Coextension_Finalization): New routine. Generate finalization
11237 attachment calls to all delayed coextensions.
11238 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
11239 the allocator is not a coextension itself and has delayed coextensions.
11240 If the current allocator is controlled, but also a coextension, delay
11241 the generation of the finalization attachment call.
11242 Rename local variable "Node" to "Nod" in order to avoid confusion with
11244 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
11245 limited types that are not inherently limited. Such an allocator is
11246 illegal, but is generated by the expander for a return statement, to
11247 copy the result onto the secondary stack. This is the only case where a
11248 limited object can be copied. Generate code to displace the pointer
11249 to the object if the qualified expression is a class-wide interface
11250 object. Such displacement was missing and hence the copy of the object
11252 (Apply_Accessibility_Check): Handle allocated objects initialized in
11254 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
11255 and Expand_Allocator_Expression. Allocating class-wide interface objects
11256 this routine displaces the pointer to the allocated object to reference
11257 the component referencing the corresponding secondary dispatch table.
11258 Expand_Allocator_Expression): Add missing support to allocate class-wide
11259 interface objects initialized with a qualified expression.
11260 (Get_Allocator_Final_List): Test for an anonymous access type that is a
11261 function result type, and use the finalization list associated with the
11262 function scope in that case (such an anonymous type should not be
11263 treated like an access parameter's type).
11265 2007-06-06 Ed Schonberg <schonberg@adacore.com>
11266 Gary Dismukes <dismukes@adacore.com>
11267 Javier Miranda <miranda@adacore.com>
11269 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
11270 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
11271 required exception handler.
11272 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
11273 properly the case of a function whose return type is a limited
11274 class-wide interface type. Modify the code of the accessibility
11275 check to handle class-wide interface objects. In this case we need to
11276 displace "this" to reference the primary dispatch table to get access
11277 to the TSD of the object (to evaluate its accessibility level).
11278 (Expand_N_Extended_Return_Statement): Test for a tagged result type
11279 rather than a controlling result as one of the conditions for
11280 generating tests of the implicit BIP_Alloc_Form formal. The
11281 initialization assignment is also handled according to whether the
11282 result is tagged instead of controlling.
11283 In the case where the init assignment is inserted in the "then" part of
11284 the allocation conditional, rewrite the target to be a dereference of
11285 the implicit BIP_Object_Access formal.
11286 If the returned value is unconstrained and created on the secondary
11287 stack, mark the enclosing block and function so that the secondary
11288 stack is not reclaimed on return.
11289 Treat returns from functions with controlling results similarly to
11290 returns from functions with unconstrained result subtypes.
11291 If the object returned is unconstrained, and an allocator must be
11292 created for it, analyze the allocator once the block for the extended
11293 return is installed, to ensure that finalizable components
11294 of the expression use the proper finalization list. Guard the call to
11295 Move_Final_List with a check that there is something to finalize.
11296 (Make_Tag_Ctrl_Assignment): Use "old" handling
11297 of controlled type assignment for virtual machines, since new code uses
11298 unsupported features (such as direct access to bytes in memory).
11300 2007-06-06 Gary Dismukes <dismukes@adacore.com>
11301 Ed Schonberg <schonberg@adacore.com>
11303 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
11304 accessibility actual, check for the case of an aliased object that has
11305 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
11306 we fall into processing for the attribute rather than the name of the
11308 (Expand_Inline_Call): If an actual is a literal, and the corresponding
11309 formal has its address taken in the body, create a temporary to capture
11310 value. If the return type is a limited interface, do not treat the
11311 return value as Controlled.
11312 (Is_In_Place_Function): If the return type is a limited interface,
11313 treat as returning in place. The actual returned object may not always
11314 be limited, but the caller has to assume that it is returned in place.
11315 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
11316 context of an allocator, use the correct finalization chain (that is,
11317 the chain belonging to the access type, rather than the chain belonging
11318 to the current scope).
11319 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
11320 result type rather than a controlling result as a precondition for
11321 adding an allocation form actual to a build-in-place call.
11322 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
11323 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
11324 primitive in the dispatch tables. This work is now done by Make_DT when
11325 the type is frozen.
11326 (Register_Predefined_DT_Entry): Removed.
11327 (Add_Return): If end label is not present, use sloc of last statement
11328 for generated return statement in procedure, for better gdb behavior

11331 object address nodes to ensure proper processing by routines like
11333 (Expand_Call): Fix generation of validity check for parameter

11335 the allocation form parameter if the result subtype is constrained,
11336 except when the function has a controlling result.
11337 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
11338 rather than Is_Controlled and Has_Controlled_Component, since we want to
11339 include class-wide result types in this treatment. Also test for a
11340 controlling result, since that also requires passing a finalization
11342 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
11343 even when the result subtype is constrained, to handle calls involving
11344 controlling results.
11345 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
11346 is now called even when the result subtype is constrained, to handle
11347 calls involving controlling results.
11348 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
11349 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
11350 now performs the test).
11351 (Make_Build_In_Place_Call_In_Object_Declaration):
11352 Add_Alloc_Form_Actual_* is now called even when the result subtype is
11353 constrained, to handle calls involving controlling results.
11354 (Add_Return): Accomodate rewritten pattern from local raise to goto
11355 transformation, so that we still recognize an transfer statement
11356 and do the right thing here in that case.
11357 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
11358 and end of subprogram code.
11359 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
11360 support for primitives that are functions (without formals) with a
11361 controlling result.
11362 (Inherited_From_Formal): If the actual subtype has not generic parent
11363 type, it is not an actual for a formal derived type, and there is no
11364 operation to inherit from the formal.

11372 exception handler for Deep_Adjust or Deep_Finalize.
11373 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
11374 Raise_From_Controlled_Operation is available, use a call to that
11375 subprogram instead of a plain "raise Program_Error" node to raise
11376 Program_Error if an exception is propagated from an Adjust or Finalize
11378 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
11379 appears in the optional statement list of a triggering alternative, the
11380 scope actions can be inserted directly there, and not in the list that
11381 includes the asynchronous select itself.
11383 2007-06-06 Ed Schonberg <schonberg@adacore.com>
11384 Robert Dewar <dewar@adacore.com>

11411 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
11412 functionality when the backend is generating code.
11413 Otherwise any serious error
11414 reported by the backend calling the frontend routine Error_Msg
11415 changes the Compilation_Mode to Check_Semantics, disables the
11416 functionality of this routine and causes the generation of
11417 spureous additional errors.
11419 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
11420 debugging information now generated by the compiler for fat-pointer
11422 Document the contents of DW_AT_producer in the GNAT Vendor extensions to

11434 stream attributes of the designated type of an RACW, as they are not
11435 dispatching primitive operations.

11455 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
11456 deallocation of class-wide interface objects.
11457 (Expand_Dispatching_Constructor_Call): Take into account that if the
11458 result of the dispatching constructor is an interface type, the
11459 function returns a class-wide interface type; otherwise the returned
11460 object would be actual. The frontend previously accepted returning
11461 interface types because Expand_Interface_Actuals silently performed
11462 the management of the returned type "as if" it were a class-wide
11464 (Expand_Dispatching_Constructor_Call): Replace call to
11465 Make_DT_Access_Action by direct call to Make_Function_Call.

11470 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
11471 compute masking constant, since we now set Esize properly to the
11473 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
11474 to match the alignment.
11475 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
11476 packed arrays of 8 bits or less.
11478 * freeze.adb (Freeze_Entity): When freezing the formals of a
11479 subprogram, freeze the designated type of a parameter of an access type
11480 only if it is an access parameter.

11483 adjusted for the alignment if it is known.
11484 (Freeze_Entity, array type case): When checking bit packed arrays for
11485 the size being incorrect, check RM_Size, not Esize.
11486 (Freeze_Record_Type): Check for bad discriminated record convention
11487 (In_Exp_Body): Return true if the body is generated for a subprogram
11488 renaming, either an attribute renaming or a renaming as body.
11489 (Check_Itype): If the designated type of an anonymous access component
11490 is a non-protected subprogram type, indicate that it is frozen, to
11491 prevent out-of-scope freeze node at some subsequent call.
11492 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
11493 only if the subprogram is neither imported nor exported, as well as the

11499 Gary Dismukes <dismukes@adacore.com>
11501 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a

11523 to apply Import to an object renaming declaration.
11525 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
11526 from a C++ class should be declared as limited and that it will be
11527 considererd limited.
11528 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
11529 should be declared as limited and that it will be considererd limited.
11530 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas

11554 object of a limited type can be initialized with a call to a function
11555 that returns in place. If the limited type has unknown discriminants,
11556 and the underlying type is a constrained composite type, build an actual
11557 subtype from the function call, as is done for private types.
11558 (Side_Effect_Free): An expression that is the renaming of an object or
11559 whose prefix is the renaming of a object, is not side-effect free
11560 because it may be assigned through the renaming and its value must be
11561 captured in a temporary.
11562 (Has_Controlled_Coextensions): New routine.
11563 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
11564 as is done for other limited types.

11614 Add new warning for renaming of function return objects
11616 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
11617 (Tree_Read): Use size of object instead of type'object_size, since the

11621 * opt.ads: Add new warning for renaming of function return objects
11622 (Generating_Code): New boolean variable used to indicate that the

11636 Standard can be renamed.
11637 (Analyze_Object_Renaming): Add new warning for renaming of function
11639 Also reject attempt to rename function return object in Ada 83 mode.
11640 (Attribute_Renaming): In case of tagged types, add the body of the
11641 generated function to the freezing actions of the type.
11642 (Find_Type): A protected type is visible right after the reserved word
11643 "is" is encountered in its type declaration. Set the entity and type

11671 (Deallocate, Dereference): Send error messages to the proper stream
11672 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
11673 documented. Previous code would send it to the current output file
11674 defined in GNAT.IO, which might not be stdout
11675 (Is_Valid): Adjust comment to mention that a positive reply means that
11676 Header_Of may be used to retrieve the allocation header associated with
11677 the subprogram Storage address argument. Return False early if this

11696 Correct error message when invocation of the linker fails
11697 Add explicit size clause for the C imported variables
11698 Object_List_File_Supported and Using_GNU_Linker to emphasize that
11699 we expect char size.
11700 Read target parameters earlier, since this is needed to set
11701 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
11704 2007-06-06 Vincent Celier <celier@adacore.com>
11707 Add 3 spaces before the default project directory when displaying
11708 the project search path.

12264 (Resolve_Allocator): Add condition to ensure that all future decoration
12265 occurs on an allocator node. Add processing and cleanup for static
12267 (Valid_Conversion): If the operand type is the limited view of a
12268 class-wide type, use the non-limited view is available to determine
12269 legality of operation.
12270 (Ambiguous_Character): move to spec, for use elsewhere.
12271 (Ambiguous_Character): Handle Wide_Wide_Character in Ada 2005 mode
12272 (Resolve_Range): Diagnose properly an ambiguous range whose bounds are
12273 character literals.
12274 (Resolve_Arithmetic_Op): Call Activate_Division_Check instead of setting
12275 Do_Division_Check flag explicitly.
12276 (Resolve_Actuals): If the actual is of a synchronized type, and the
12277 formal is of the corresponding record type, this is a call to a
12278 primitive operation of the type, that is declared outside of the type;
12279 the actual must be unchecked-converted to the type of the actual
12280 (Resolve_Call): Kill all current values for any subprogram call if
12281 flag Suppress_Value_Tracking_On_Call is set.

12288 allocator's access type.
12289 (Resolve_Allocator): In the case of an allocator initialized by an
12290 aggregate of a discriminated type, check that associations for any
12291 access discriminants satisfy accessibility requirements by calling

12303 whether an implicit 'Access reference or implicit dereference must be
12304 added to make the actual conform to the controlling formal.

12314 both entities. This is required to statically build the dispatch table.
12315 (Declare_Inherited_Private_Subprograms): Rewriten to avoid the need
12316 of calling Set_All_DT_Position to re-evaluate the position of the
12317 entries in the dispatch table. Such reevaluation is not desired if

12388 (Rmsg_28): Fix description for E.4(18) check.
12389 (Raise_Current_Excep): Call Debug_Raise_Exception just before
12390 propagation starts, to let debuggers know about the event in a reliable
12392 Take the address of E and dereference to make sure it is homed on stack
12393 and prevent the stores from being deleted, necessary for proper

13188 parameter, rewrite the call as the indexing of a call with a single
13189 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
13191 (Resolve_Actuals): If an actual is an allocator for an access parameter,
13192 the master of the created object is the innermost enclosing statement.
13193 (Remove_Conversions): For a binary operator, check if type of second
13194 formal is numeric, to check if an abstract interpretation is present

13357 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
13358 "abstract subprograms must be visible" message, whether or not the type

13436 attempt to derive from a synchronized tagged type.

13441 that use (a subtype of) the class-wide type of the enclosing type.
13442 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
13443 Derived_Type for Prev formal on call to
13444 Check_Anonymous_Access_Components rather than Empty.
13445 (Make_Incomplete_Type_Declaration): Add test for case where the type has
13446 a record extension in deciding whether to create a class-wide type,

13527 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
13528 when -gnatg is not specified.

13563 initialize record controller if needed, before the components, to ensure
13564 that they are properly finalized.
13565 (Build_Record_Aggr_Code): For the case of an array component that has a
13566 corresponding array aggregate in the record aggregate, perform sliding

13570 Gary Dismukes <dismukes@adacore.com>
13571 Ed Schonberg <schonberg@adacore.com>
13573 * exp_ch13.adb (Expand_External_Tag_Definition): Replace call to the
13574 run-time subprogram Set_External_Tag by call to Build_Set_External_Tag.
13576 * exp_ch4.adb (Expand_Allocator_Expression): Don't perform a run-time
13577 accessibility on class-wide allocators if the allocator occurs at the
13578 same scope level as the allocator's type. The check is guaranteed to
13579 succeed in that case, even when the expression originates from a
13580 parameter of the containing subprogram.
13581 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
13582 under No_Dispatching_Calls restriction. During the semantic analysis
13583 we already notified such violation.
13584 (Tagged_Membership): Constant folding. There is no need to check
13585 the tag at run-time if the type of the right operand is non
13586 class-wide abstract.
13587 Replace call to Is_Ancestor by call to Is_Parent
13588 to support concurrent types with interface types.
13589 (Expand_N_Allocator): Add an assertion associated with the generation
13591 (Expand_N_Slice): Do not enable range check to nodes associated
13592 with the frontend expansion of the dispatch table.

13596 subprogram CW_Membership by call to Build_CW_Membership.
13597 (Expand_Allocator_Expression): Replace generation of call to the
13598 run-time subprogram Get_Access_Level by call to Build_Get_Access_Level.
13600 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
13601 initialize most the TSD components by means of an aggregate.
13602 Modify the declaration of the object containing the TSD
13603 because we now expand code that has a higher level of abstraction.
13604 The TSD has a discriminant containing the Inheritance Depth Level,
13605 value that is used in the membership test but also to fix the size
13606 of the table of ancestors.
13607 (Expand_Interface_Conversion): Insert function body at the closest place
13608 to the conversion expression, to prevent access-before-elaboration
13609 errors in the backend.
13610 Code improved to reduce the size of the dispatch table if
13611 compiling under restriction No_Dispatching_Calls plus code cleanup.
13612 Code reorganization plus removal of calls to Set_Num_Prim_Ops
13613 (Make_Secondary_DT): Remove call to Set_Num_Prim_Ops.
13614 (Expand_Dispatching_Call): Minor code reorganization plus addition of
13615 code to return immediately if compiling under No_Dispatching_Calls
13617 (Set_All_DT_Position): Remove code associated with the old CPP pragmas.
13618 CPP_Virtual and CPP_Vtable are no longer supported.
13619 (Expand_Interface_Conversion): Add missing support for interface type
13621 (Expand_Interface_Actuals): Replace calls to Is_Ancestor by calls to
13622 Is_Parent to support concurrent types with interfaces.

13625 (Set_All_DT_Position): Modified to support concurrent record types.
13626 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entries associated
13627 with Get_External_Tag, Inherit_TSD, Set_External_Tag.
13628 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entry associated
13629 with CW_Membership.
13630 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entries associated
13631 with Get_Access_Level, Get_Predefined_Prim_Op_Address,
13632 Get_Prim_Op_Address Get_RC_Offset, Get_Remotely_Callable, Inherit_DT,
13633 Set_Access_Level, Set_Expanded_Name, Set_Predefined_Prim_Op_Address,
13634 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
13635 (Expand_Dispatching_Call): Replace generation of call to the run-time
13636 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
13637 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
13639 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
13640 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
13641 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
13642 Build_Set_Prim_Op_Address.
13643 (Get_Remotely_Callable): Subprogram removed.
13644 (Init_Predefined_Interface_Primitives): Replace generation of call to
13645 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
13648 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
13649 First (Parameter_Associations ()) with the call to First_Actual that
13650 returns an actual parameter expression for both named and positional
13653 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
13654 check violation of restriction No_Dispatching_Calls.
13655 (Check_Controlling_Type): A formal of a tagged incomplete type is a
13656 controlling argument.
13658 * exp_util.ads, exp_util.adb (Type_May_Have_Bit_Aligned_Components): Use
13659 First/Next_Component_Or_Discriminant
13660 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
13661 (Find_Implemented_Interface): Removed. All the calls to this subprogram
13662 specify Any_Limited_Interface, and this functionality is already
13663 provided by the function Has_Abstract_Interfaces.
13664 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
13665 support concurrent types implementing interfaces.
13666 (Find_Implemented_Interface): Removed. All the calls to this subprogram
13667 specify kind Any_Limited_Interface, and this functionality is already
13668 provided by the function Has_Abstract_Interfaces.
13669 (Remove_Side_Effects): replace Controlled_Type by
13670 CW_Or_Controlled_Type whenever the issue is related to
13671 using or not the secondary stack.
13673 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
13674 P_Interface_Type_Definition to fulfill the new interface (the formal
13675 Is_Synchronized is no longer required).
13677 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
13678 Update dependencies.
13680 * exp_atag.ads, exp_atag.adb: New file

13684 Cyrille Comar <comar@adacore.com>
13686 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
13687 anonymous, use finalization list of enclosing dynamic scope.
13688 (Expand_N_Package_Declaration): For a library package declaration
13689 without a corresponding body, generate RACW subprogram bodies in the
13690 spec (just as we do for the task activation call).
13691 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
13692 Is_Abstract_Type. Make sure these are called only when appropriate.
13693 Remove all code for DSP option
13694 (CW_Or_Controlled_Type): new subprogram.

13698 Gary Dismukes <dismukes@adacore.com>
13700 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
13701 parameter. If it is set to true, return a result capped according to
13702 the global upper bound for the index of an entry family.
13703 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
13704 (Build_Find_Body_Index): Adjust for above change.
13705 (Entry_Index_Expression): Likewise.
13706 (Is_Potentially_Large_Family): New function extracted from...
13707 (Collect_Entry_Families): ...here. Call it to detect whether the family
13708 is potentially large.
13709 (Build_Entry_Count_Expression): If the family is potentially large, call
13710 Family_Size with 'Cap' set to true.
13711 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
13712 a protected version of an operation declared in the private part of
13713 a protected object, because they may be invoked through a callback.
13714 (Set_Privals): If the type of a private component is an anonymous access
13715 type, do not create a new itype for each protected body.
13716 If the body of a protected operation creates
13717 controlled types (including allocators for class-widetypes), the
13718 body of the corresponding protected subprogram must include a
13720 (Build_Activation_Chain_Entity): Build the chain entity for extended
13722 (Type_Conformant_Parameters): Use common predicate Conforming_Types
13723 to determine whether operation overrides an inherited primitive.
13724 (Build_Wrapper_Spec): Add code to examine the parents while looking
13725 for a possible overriding candidate.
13726 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
13727 hold an actual parameter value since its initialization is separated
13728 from the the declaration. Prevents errors on null-excluding access
13731 2007-04-06 Thomas Quinot <quinot@adacore.com>
13732 Pablo Oliveira <oliveira@adacore.com>
13734 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
13735 Do an Unchecked_Conversion to handle the passage from the Underlying
13736 Type to the Base Type when calling Build_To_Any_Call and
13737 Build_From_Any_Call.
13738 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
13739 E_Constant, depending upon Variable formal.
13740 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13741 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
13742 parameter that requires an extra constrained parameter, declare
13743 temporary for actual as a variable, not a constant.
13744 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
13745 the unit being compiled is the one that contains the stub type.
13746 Change primitive operation name for the RACW associated with a RAS
13747 from Call to _Call so it cannot clash with any legal identifier.
13748 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
13750 (Append_RACW_Bodies): New subprogram.
13751 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
13752 Add_Receiving_Stubs_To_Declarations functions.
13753 When expanding a package body, this list correspond to the
13754 statements in the HSS at the end of the pacakge.
13755 When expanding a package spec, this list correspond to the
13757 (Add_Receiving_Stubs_To_Declarations): Append the function
13758 registering the receiving stubs at the end of the 'Stmts' list.
13759 (RCI_Package_Locator): Pass the new Version generic formal when
13760 instantiating a RCI_Locator package.
13761 (Build_From_Any_Function): To compute the High bound for an
13762 unconstrained array actual, we add the Low bound with the length.
13763 Thus we must convert the low bound and the length to an appropriate
13764 type before doing the sum.
13765 (Build_Subprogram_Receiving_Stubs, PolyORB):
13766 * Retrieve the extra formals parameters at the
13767 end of the parameter stream.
13768 * Use Move_Any_Value to write back out parameters
13769 after executing the request as it is more efficient
13770 than Copy_Any_Value.
13771 * Build the any containing Extra Formals with the
13772 appropriate typecode.
13773 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
13774 empty Component_List.
13775 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
13776 the tree the declaration for an object that serves as actual parameter
13777 in server-side stubs.
13778 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13779 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13780 Use Build_Actual_Object_Declaration to prepare the actuals.

13782 Extra Constrained Parameters.
13783 (Build_General_Calling_Stubs): Set the parameter type to boolean for
13784 Extra Constrained parameters.

13786 Built_TypeCode_Function): When Typ is implicit, call the correct
13787 function with the first not implicit parent type.
13788 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
13789 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
13790 typecode from the Etype. Therefore we retrieve the correct typecode
13791 with a call to Get_Any_Type.
13792 (Copy_Specification): Do controlling formal type substitution based on
13793 Is_Controlling_Formal flag, instead of caller-provided object type.
13794 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
13795 a RACW primitive operation, we might get a subprogram declaration for an
13796 ancestor of the RACW designated type (not for the designated type
13797 itself), in the case where this operation is inherited. In this case we
13798 have no easy means of determining the original tagged type for which
13799 the primitive was declared, so instead we now rely on
13800 Copy_Specification to use the Is_Controlling_Formal flag to determine
13801 which formals require type substitution.

13804 Ed Schonberg <schonberg@adacore.com>
13806 * exp_intr.adb (Expand_Exception_Call): Calls to subprograms in
13807 GNAT.Current_Exception are not allowed if pragma Restrictions
13808 (No_Exception_Propagation) is set and in any case make the associated
13809 handler unsuitable as a target for a local raise statement.
13810 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
13811 run-time subprogram CW_Membership by call to Build_CW_Membership.
13812 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
13813 by a function call, a temporary must be created before expanding the
13814 Constructor_Call itself, to prevent out-of-order elaboration in the
13815 back-end when stack checking is enabled..
13817 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13819 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
13820 result are the bounds of the left operand, not the right.
13822 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13825 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use
13826 discriminant defaults.

13831 Bob Duff <duff@adacore.com>
13833 * sem_aggr.adb (Resolve_Record_Aggregate): In semantics-only mode treat
13834 an association with a box as providing a value even though the
13835 initialization procedure for the type is not available.
13836 (Resolve_Record_Aggregate): Check that a choice of an association with a
13837 box corresponds to a component of the type.
13838 (Resolve_Record_Aggregate): Split Is_Abstract flag into
13839 Is_Abstract_Subprogram and Is_Abstract_Type.
13841 * exp_tss.adb (Base_Init_Proc): Use Is_Type instead of Type_Kind for
13844 * inline.adb (Add_Inlined_Body): Split Is_Abstract flag into
13845 Is_Abstract_Subprogram and Is_Abstract_Type. Make sure these are
13846 called only when appropriate.
13848 2007-04-06 Olivier Hainque <hainque@adacore.com>
13850 * g-alleve.ads (Low Level Vector type definitions): Map each to the
13851 associated vector view instead of all to the unsigned char view.
13853 * g-altcon.adb (Generic_Conversions): New internal generic package,
13854 offering facilities for all the Vector/View conversion routines
13855 implemented by this unit.

13896 (GNATCmd): Update the B_Start variable if we are in a VMS environment.
13897 Add gnatstack to the list of commands that use project file related
13898 switches, and get the single attribute Switches from the stack package
13899 in a project file when calling gnatstack. Parse the -U flag for
13900 processing files belonging to all projects in the project tree.
13901 Remove all processing for command Setup

13936 * i-cstrea.ads: (fopen): Add encoding parameter.
13938 Change reference from a-sysdep.c to sysdep.c in comment.
13939 Update copyright notice.
13940 This set of patch add support for the encoding form parameter.
13942 * mingw32.h (S2WSU): New macro to convert from a string to a
13943 wide-string using the UTF-8 encoding. The S2WS macro supports now only
13944 standard 8bits encoding.
13945 (WS2SU): As above but converting from wide-sring to string.
13946 This is needed as it is necessary to have access to both versions in the
13947 runtime for the form parameter encoding support.
13948 This set of patch add support for the encoding form parameter.
13949 (S2WS): Improve implementation to handle cases where the filename is not
13950 UTF-8 encoded. In this case we default to using the current code page
13951 for the conversion.
13953 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
13954 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

13956 (fopen): Add encoding parameter.
13959 * s-ficobl.ads (AFCB): Add Encoding field to record the filename
13960 encoding. This is needed for the Reset routine (freopen low level-call).
13962 * s-fileio.adb (Open): Decode encoding form parameter and set the
13963 corresponding encoding value into AFCB structure.
13964 (Reset): Pass the encoding value to freopen.
13965 (Close): Move the call to Lock_Task to the beginning of the procedure.

13998 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
13999 __gnat_adjust_context_for_raise.
14000 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
14001 implementation of floating point operations as native x86 targets.
14002 So the FPU should be initialized in the same way using finit. Fix

14023 * lib-xref.ads, lib-xref.adb:
14024 Modify the loop that collects type references, to include interface
14025 types that the type implements. List each of these interfaces when
14026 building the entry for the type.
14027 (Generate_Definition): Initialize component Def and Typ of new entry
14028 in table Xrefs, to avoid to have these components unitialized.
14029 (Output_References): Split Is_Abstract flag into
14030 Is_Abstract_Subprogram and Is_Abstract_Type.
14031 (Generate_Reference): Add barrier to do not generate the warning
14032 associated with Ada 2005 entities with entities generated by the

14072 2007-04-06 Robert Dewar <dewar@adacore.com>
14074 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
14075 it no longer destroys the contents of Name_Buffer or Name_Len and
14076 non-standard and invalid names are handled better.
14077 (Get_Decoded_Name_String): Improve performance by using
14078 Name_Has_No_Encodings flag in the name table.
14079 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
14080 Used for debugging printouts.

14083 Javier Miranda <miranda@adacore.com>
14084 Bob Duff <duff@adacore.com>
14086 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
14087 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
14088 there is no need to generate always a record_definition_node in case
14089 of synchronized interface types.
14090 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
14091 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
14092 illegal in Ada 95, in cases where it is legal. Change the warnings to
14093 errors in other cases. Don't give the error unless the "not null"
14094 parses properly. Correct the source position at which the error occurs.
14095 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
14096 P_Null_Exclusion, to suppress "not null" warnings.

14148 Entry for pragma Unreferenced_Objects
14150 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
14151 switches, without repetition of "eD". Make sure that last character of
14152 -gnatep= switch is not taken as -gnat switch character.
14153 Complete rewrite of circuit for handling saving compilation options

14172 the default project path, initially done during elaboration of the
14174 If the prefix returned by Sdefault is null, get the prefix from a call
14175 to Executable_Prefix_Path.
14176 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
14179 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
14180 canonical directory name to open the directory from which files are
14182 (Record_Other_Sources): Idem.
14183 (Locate_Directory): Add the possibility to create automatically missing
14184 directories when Setup_Projects is True.
14185 Call Locate_Directory so that the directory will be created when
14186 Setup_Projects is True, for object dir, library dir, library ALI dir,
14187 library source copy dir and exec dir.
14189 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
14192 2007-04-06 Robert Dewar <dewar@adacore.com>

14207 Next_Component_Or_Discriminant.
14209 * style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
14212 * stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch
14213 Include -gnatyA in default switches

14226 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
14227 full word is no longer compared twice.
14229 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14231 * sem_ch10.adb (Install_Limited_Context_Clauses.
14232 Expand_Limited_With_Clause): Use a new copy of selector name in the
14233 call to Make_With_Clause. This fixes the tree structure for ASIS
14234 purposes. Nothing is changed in the compiler behaviour.
14235 (Process_Body_Clauses): Handle properly use clauses whose prefix is
14236 a package renaming.
14237 (Install_Limited_With_Clauses): Do not install non-limited view when it
14238 is still incomplete.
14240 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14241 Gary Dismukes <dismukes@adacore.com>
14243 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
14244 when capturing size information, instead of base type, which for a
14245 formal array type will be the unconstrained type.
14246 (Analyze_Formal_Object_Declaration): Add check for illegal default
14247 expressions for a formal in object of a limited type.
14248 (Instantiate_Object): Ditto.
14249 (Check_Formal_Package_Instance): Skip entities that are formal objects,
14250 because they were defaulted in the formal package and no check applies
14252 (Check_Formal_Package_Instance): Extend conformance check to other
14253 discrete types beyond Integer.
14254 (Process_Default): Copy directly the unmatched formal. A generic copy
14255 has already been performed in Analyze_Formal_Package.
14256 (Analyze_Associations): If a formal subprogram has no match, check for
14257 partial parametrization before looking for a default, to prevent
14259 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
14260 not set the instantiation environment before analyzing the actuals.
14261 Fixes regression on 8515-003 with implementation of AI-133.
14262 Set_Instance_Env checks whether the generic unit is a predefined
14263 unit, in which case the instance must be analyzed with the latest Ada
14264 mode. This setting must take place after analysis of the actuals,
14265 because the actuals must be analyzed and frozen in the Ada mode extant
14266 outside of the current instantiation.
14267 (Save_Env, Restore_Env): Preserve and restore the configuration
14268 parameters so that predefined units can be compiled in the proper Ada
14270 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
14271 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
14272 and Is_Abstract_Type.
14273 (Analyze_Formal_Package): For better error recovery, Add exception
14274 handler to catch Instantion_Error, which can be raised in
14275 Analyze_Associations
14277 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14278 Bob Duff <duff@adacore.com>
14279 Gary Dismukes <dismukes@adacore.com>
14281 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
14282 prefix type is a discriminated subtype of the type of the formal.
14283 (Analyze_Allocator): Collect all coextensions regardless of the context.
14284 Whether they can be allocated statically is determined in exp_ch4.
14285 (Analyze_Selected_Component): If the prefix is a limited view and the
14286 non-limited view is available, use the non-limited one.
14287 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
14288 therefore illegal), suggest a qualified expression rather than a type
14289 conversion, because a type conversion would be illegal in this context.
14290 (Anayze_Allocator): Trace recursively all nested allocators so that all
14291 coextensions are on the corresponding list for the root. Do no mark
14292 coextensions if the root allocator is within a declaration for a stack-
14293 allocated object, because the access discriminants will be allocated on
14295 (Analyze_Call): Remove restriction on calls to limited functions for the
14296 cases of generic actuals for formal objects, defaults for formal objects
14297 and defaults for record components.
14298 (Analyze_Allocator): Before analysis, chain coextensions on the proper
14299 element list. Their expansion is delayed until the enclosing allocator
14300 is processed and its finalization list constructed.
14301 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
14302 for an operation with the given name among the primitive operations of
14303 the corresponding record type.
14304 (Analyze_Selected_Component): If the prefix is a task type that
14305 implements an interface, and there is no entry with the given name,
14306 check whether there is another primitive operation (e.g. a function)
14308 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
14309 properly the indexing of a function call written in prefix form, where
14310 the function returns an array type, and all parameters of the function
14311 except the first have defaults.
14312 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
14313 the original operands, rather than relocating them, for efficiency and
14314 to work properly when an operand is overloaded.
14315 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
14316 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
14317 (Analyze_Selected_Component): If the prefix is a private extension, only
14318 scan the visible components, not those of the full view.
14319 (Try_Primitive_Operation): If the operation is a procedure, collect all
14320 possible interpretations, as for a function, because in the presence of
14321 classwide parameters several primitive operations of the type can match
14322 the given arguments.
14324 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14325 Robert Dewar <dewar@adacore.com>
14327 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
14328 tag-indeterminate call to an abstract function, when the left-hand side
14330 (Analyze_Loop_Statement): Improve detection of infinite loops
14332 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14333 Thomas Quinot <quinot@adacore.com>
14335 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
14336 out of Analyze_Package_Declaration, because processing must be applied
14337 to package bodies as well, for deferred constants completed by pragmas.
14338 (Analyze_Package_Declaration): When the package declaration being
14339 analyzed does not require an explicit body, call Check_Completion.
14340 (May_Need_Implicit_Body): An implicit body is required when a package
14341 spec contains the declaration of a remote access-to-classwide type.
14342 (Analyze_Package_Body): If the package contains RACWs, append the
14343 pending subprogram bodies generated by exp_dist at the end of the body.
14344 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
14345 Is_Abstract_Subprogram and Is_Abstract_Type.
14346 (Preserve_Full_Attributes): The full entity list is not an attribute
14347 that must be preserved from full to partial view.
14349 * sem_dist.adb (Add_RAS_Dereference_TSS):
14350 Change primitive name to _Call so it cannot clash with any legal
14351 identifier, and be special-cased in Check_Completion.
14352 Mark the full view of the designated type for the RACW associated with
14353 a RAS as Comes_From_Source to get proper view switching when installing
14354 private declarations.
14355 Provite a placeholder nested package body along with the nested spec
14356 to have a place for Append_RACW_Bodies to generate the calling stubs
14357 and stream attributes.
14359 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14360 Robert Dewar <dewar@adacore.com>
14362 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
14363 that is a limited view, check the non-limited view if available.
14364 (Undefined): Refine error message for missing with of Text_IO
14365 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
14366 to distinguish real missing with cases.
14367 Fix format of all missing with messages
14368 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
14369 renaming as body when renamed entity is abstract.
14371 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14372 Javier Miranda <miranda@adacore.com>
14374 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make

14383 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14384 Javier Miranda <miranda@adacore.com>
14386 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
14387 dereference of a local object R created as a reference to another
14388 object O, use the access level of O.
14389 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
14390 rather than local Same_Formal_Type, to check whether protected operation
14391 overrides an inherited one.
14392 (Same_Formal_Type): New predicate, used when matching signatures of
14393 overriding synchronized operations, to handle the case when a formal
14394 has a type that is a generic actual.
14395 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
14396 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
14397 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
14398 syntactic ambiguities involving indexing of function calls that return
14400 (Abstract_Interface_List): New subprogram that returns the list of
14401 abstract interfaces associated with a concurrent type or a
14402 concurrent record type.
14403 (Interface_Present_In_Parent): New subprogram used to check if a
14404 given type or some of its parents implement a given interface.
14405 (Collect_Abstract_Interfaces): Add support for concurrent types
14406 with interface types.
14407 (Has_Abstract_Interfaces): Add support for concurrent types with
14409 (Is_Parent): New subprogram that determines whether E1 is a parent
14410 of E2. For a concurrent type its parent is the first element of its
14411 list of interface types; for other types this function provides the
14412 same result than Is_Ancestor.
14413 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
14414 (Collect_Synchronized_Interfaces): Removed because the subprogram
14415 Collect_Abstract_Interfaces provides this functionality.
14416 (Collect_Abstract_Interfaces): Minor update to give support to
14417 concurrent types and thus avoid undesired code duplication.
14418 (Get_Subprogram_Entity): Handle entry calls.
14419 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
14421 (Enter_Name): Do not give -gnatwh hiding warning for record component
14422 entities, they never result in hiding.

14425 Robert Dewar <dewar@adacore.com>
14427 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,
14428 to chain nested components that are allocators for access discriminants
14429 of the enclosing object.
14430 Add N_Push and N_Pop nodes
14431 New field Exception_Label added
14432 (Local_Raise_Statements): New field in N_Exception_Handler_Node
14433 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node
14434 (Is_Coextension): New flag for allocators, to mark allocators that
14435 correspond to access discriminants of dynamically allocated objects.
14436 (N_Block_Statement): Document the fact that the corresponding entity
14437 can be an E_Return_Statement.
14438 (Is_Coextension): New flag for allocators.
14439 Remove all code for DSP option
14441 * sprint.ads, sprint.adb: Display basic information for class_wide
14442 subtypes. Add handling of N_Push and N_Pop nodes

14446 * s-tpobop.adb (Exceptional_Complete_Entry_Body): Undefer abortion
14447 before propagating exception.
14449 2007-04-06 Olivier Hainque <hainque@adacore.com>
14451 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
14452 an address always within the call instruction from a return address.
14454 2007-04-06 Olivier Hainque <hainque@adacore.com>
14455 Eric Botcazou <botcazou@adacore.com>
14457 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
14458 expression with a COMPOUND_EXPR including the call instead of emitting
14459 the call directly here.
14460 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
14461 high bound is constant and the slice is empty. Tidy.
14462 (tree_transform, case N_Op_Not): Handle properly the case where the
14463 operation applies to a private type whose full view is a modular type.
14464 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
14465 Address_Clause, use the associated Expression as the GNAT tree

14752 anonymous access types.
14753 (Valid_Conversion): For a conversion to a numeric type occurring in an

15038 alignment of a field in a variant record might not be accurate. Add a
15039 safety test to make sure no alignment is set to a smaller value than
15040 the alignment of the field type.

15460 the parent part is a build-in-place function call, generate assignments.
15461 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
15462 are build-in-place function calls.
15463 (Replace_Self_Reference): New subsidiary of
15464 Make_OK_Assignment_Statement, to replace an access attribute that is a
15465 self-reference into an access to the appropriate component of the
15466 target object. Generalizes previous mechanism to handle self-references
15467 nested at any level.
15468 (Is_Self_Referential_Init): Remove, not needed.
15469 (Is_Self_Referential_Init): New predicate to simplify handling of self
15470 referential components in record aggregates.
15471 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
15472 check for presence of entity before checking for self-reference.
15473 (Has_Default_Init_Comps): Return True if a component association is a
15474 self-reference to the enclosing type, which can only come from a
15475 default initialization.
15476 (Make_OK_Assignment_Statement): If the expression is of the form
15477 Typ'Acc, where Acc is an access attribute, the expression comes from a
15478 default initialized self-referential component.
15479 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
15480 that has been derived from several abstract interfaces we must also
15481 initialize the tags of the secondary dispatch tables.

15486 Robert Dewar <dewar@adacore.com>
15489 (Expand_Access_To_Protected_Op): If the context indicates that an access
15490 to a local operation may be transfered outside of the object, create an
15491 access to the wrapper operation that must be used in an external call.
15492 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
15493 target, pass the Valid attribute applied to a floating-point prefix on
15494 to the back end without expansion.
15495 (Storage_Size): Use the new run-time function Storage_Size to retrieve
15496 the allocated storage when it is specified by a per-object expression.
15497 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
15498 Nothing to do here, the attribute has been rewritten during semantic

15507 into a fat pointer.
15508 (Is_Constrained_Aliased_View): New predicate to help determine whether a
15509 subcomponent's enclosing variable is aliased with a constrained subtype.
15510 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
15511 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
15512 an aliased prefix must be known to be constrained in order to use True
15513 for the attribute value, and now it's possible for some aliased views
15514 to be unconstrained.
15516 2006-10-31 Robert Dewar <dewar@adacore.com>
15518 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
15519 (Expand_Entity_Reference): Correct error of not handling subprogram
15520 formals in current_value processing.
15522 2006-10-31 Javier Miranda <miranda@adacore.com>

15525 Gary Dismukes <dismukes@adacore.com>
15527 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
15528 register in the final list objects containing class-wide interfaces;
15529 otherwise we incorrectly register the tag of the interface in the final
15531 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
15532 generate the wrapper if the parent primitive is abstract. This is
15533 required to report the correct error message.
15534 (Expand_N_Subtype_Indication): Do validity checks on range
15535 (Clean_Task_Names): If an initialization procedure includes a call to
15536 initialize a task (sub)component, indicate that the procedure will use
15537 the secondary stack.
15538 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
15539 compatibility for interfacing with CPP by default.
15540 (Expand_N_Object_Declaration): Only build an Adjust call when the
15541 object's type is a nonlimited controlled type.
15542 * exp_ch3.adb: Add with and use of Exp_Ch6.
15543 (Expand_N_Object_Declaration): Check for object initialization that is a
15544 call to build-in-place function and apply Make_Build_In_Place_Call_In_
15545 Object_Declaration to the call.
15546 (Freeze_Type): When the designated type of an RACW was not frozen at the
15547 point where the RACW was declared, validate the primitive operations
15548 with respect to E.2.2(14) when it finally is frozen.
15549 (Build_Initialization_Call,Expand_Record_Controller): Rename
15550 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
15551 return-by-reference has no meaning in Ada 2005.
15552 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
15553 to register tag of the immediate ancestor interfaces in the
15554 run-time structure.
15555 (Init_Secondary_Tags): Moved to the specification to allow the
15556 initialization of extension aggregates with abstract interfaces.
15557 (Build_Master_Renaming): Make public, for use by function declarations
15558 whose return type is an anonymous access type.
15559 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
15560 Insert_List_Before_And_Analyze after the generation of the specs
15561 associated with null procedures.
15562 (Expand_Tagged_Root): Update documentation in its specification.
15563 (Init_Secondary_Tags): Update documentation.
15564 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
15565 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
15566 then generate code to inherit the contents of the dispatch table
15567 directly from the ancestor.
15568 (Expand_Record_Controller): Insert controller component after tags of
15569 implemented interfaces.
15570 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
15571 create null procedure overridings when null procedures are inherited
15573 (Make_Null_Procedure_Specs): New procedure to generate null procedure
15574 declarations for overriding null primitives inherited from interfaces.
15575 (Is_Null_Interface_Procedure): New function in
15576 Make_Null_Procedure_Specs.
15577 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
15578 immediate ancestor of a tagged type is an abstract interface type we
15579 must generate the specification of the predefined primitives associated
15580 with controlled types (because the dispatch table of the ancestor is
15581 null and hence these entries cannot be inherited). This is required to
15582 elaborate well the dispatch table.

15592 (Expand_N_In): Do validity checks on range
15593 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
15594 (Expand_N_Allocator): For "new T", if the object is constrained by
15595 discriminant defaults, allocate the right amount of memory, rather than
15596 the maximum for type T.
15597 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
15598 when the allocator is initialized by a build-in-place call, since the
15599 allocator is already rewritten as a reference to the function result,
15600 and this prevents an unwanted duplication of the function call.
15601 Add with and use of Exp_Ch6.
15602 (Expand_Allocator_Expresssion): Check for an allocator whose expression
15603 is a call to build-in-place function and apply
15604 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
15605 untagged designated types).
15606 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
15607 optimization if source or target is biased.
15608 (Expand_N_Allocator): Add comments for case of an allocator within a
15609 function that returns an anonymous access type designating tasks.
15610 (Expand_N_Allocator): apply discriminant checks for access
15611 discriminants of anonymous access types (AI-402, AI-416)

15620 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
15621 (Expand_N_Assignment_Statement): Call
15622 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
15623 build-in-place function call. Currently, this can happen only for
15624 assignments that come from aggregates.
15625 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
15626 in order to alleviate the upward compatibility introduced by AI-318.
15627 (Expand_N_Extended_Return_Statement): Add support for handling the
15628 return object as a build-in-place result.
15629 (Expand_Non_Function_Return): Implement simple return statements nested
15630 within an extended return.
15631 (Enable_New_Return_Processing): Turn on the new processing of return
15633 (Expand_Non_Function_Return): For a return within an extended return,
15634 don't raise Program_Error, because Sem_Ch6 now gives a warning.
15635 (Expand_N_Extended_Return_Statement): Implement AI-318
15636 (Expand_Simple_Function_Return): Ditto.
15637 (Expand_N_If_Statement): Handle new -gnatwt warning

15639 (Expand_N_Assignment): Handle assignment to the Priority attribute of
15640 a protected object.
15641 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
15642 validity checking of assignments to elementary record components.
15643 (Expand_N_Return_Statement): return Class Wide types on the secondary
15644 stack independantly of their controlled status since with HIE runtimes,
15645 class wide types are not potentially controlled anymore.
15647 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
15650 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
15651 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
15652 it expects a block, procedure, or task. The return statement will get
15653 turned into a block, and Expand_Cleanup_Actions will happen then.

15657 Bob Duff <duff@adacore.com>
15658 Gary Dismukes <dismukes@adacore.com>
15660 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
15662 (Expand_Inlined_Call): Tagged types are by-reference types, and
15663 therefore should be replaced by a renaming declaration in the expanded
15664 body, as is done for limited types.
15665 (Expand_Call): If this is a call to a function with dispatching access
15666 result, propagate tag from context.
15667 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
15669 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
15670 build-in-place when the right-hand side of an assignment is a
15671 build-in-place function call.
15672 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
15673 of the explicit dereference of the allocator to the result subtype of
15674 the build-in-place function. This is needed to satisfy type checking
15675 in cases where the caller's return object is created by an allocator for
15676 a class-wide access type and the type named in the allocator is a
15678 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
15679 conversion of the reference to the declared object to the result subtype
15680 of the build-in-place function. This is needed to satisfy type checking
15681 in cases where the declared object has a class-wide type. Also, in the
15682 class-wide case, change the type of the object entity to the specific
15683 result subtype of the function, to avoid passing a class-wide object
15684 without explicit initialization to the back end.
15685 (Register_Interface_DT_Entry): Moved outside the body of
15686 Freeze_Subprogram because this routine is now public; it is called from
15687 Check_Dispatching_Overriding to handle late overriding of abstract
15688 interface primitives.
15689 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
15690 adding an implicit access actual on a call to a build-in-place function.
15691 (Expand_Actuals): Test for an actual parameter that is a call to a
15692 build-in-place function and apply
15693 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
15694 (Is_Build_In_Place_Function): New function to determine whether an
15695 entity is a function whose calls should be handled as build-in-place.
15696 (Is_Build_In_Place_Function_Call): New function to determine whether an
15697 expression is a function call that should handled as build-in-place.
15698 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
15699 calls to build-in-place functions as the initialization of an allocator.
15700 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
15701 handling calls to build-in-place functions in contexts that do not
15702 involve init of a separate object (for example, actuals of subprogram
15704 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
15705 handling calls to build-in-place functions as the initialization of an
15706 object declaration.

15708 instantiation of Traverse_Body to avoid unreferenced warning.
15709 (Check_Overriding_Inherited_Interfaces): Removed.
15710 (Register_Interface_DT_Entry): Code cleanup.
15711 (Register_Predefined_DT_Entry): Code cleanup.
15712 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
15713 inlined statements if within a transient scope.
15714 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
15715 formal parameters with occurrences of actuals in inlined body, establish
15716 visibility on the proper view of the actual's subtype for the body's
15718 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
15719 compatibility mode and we have an imported CPP subprogram because
15720 for now we assume that imported CPP primitives correspond with
15721 objects whose constructor is in the CPP side (and therefore we
15722 don't need to generate code to register them in the dispatch table).
15723 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
15724 aligned selected component.
15725 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
15726 the actual of an in-mode parameter is a type conversion.
15727 (Expand_Actuals): If the call does not come from source and the actual
15728 is potentially misaligned, let gigi handle it rather than rejecting the
15729 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
15730 Class Wide types as returning by reference independantly of their
15731 controlled status since with HIE runtimes class wide types are not
15732 potentially controlled anymore.
15734 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15736 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
15737 references that are private components of the protected object.

15739 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
15740 instantiation to deal with warnings.

15747 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
15748 initialization of Homonym_Len.
15749 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
15750 names from fully qualified name. Fixes problem of duplicate
15751 external names differing only in the presence of such a block name.
15753 2006-10-31 Thomas Quinot <quinot@adacore.com>
15754 Pablo Oliveira <oliveira@adacore.com>
15756 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
15757 subprogram Ids, even if they are not yet assigned.
15758 (Build_Subprogram_Id): It is now this function that will take care of
15759 calling Assign_Subprogram_Ids if necessary.
15760 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
15761 should be done only once they are assigned.
15762 (Build_From_Any_Function, case of tagged types): Add missing call to

15765 type for an RACW type.
15766 (Add_RACW_Features): When processing an RACW declaration for which the
15767 designated type is already frozen, enforce E.2.2(14) rules immediately.
15768 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
15769 special reordering of controlling formals.
15771 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
15772 associated stub type for an RACW type.
15774 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15776 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
15777 fixed-point operations in an integer context, i.e. as operands of a
15778 conversion to an integer type, indicate that result must be rounded.
15780 2006-10-31 Robert Dewar <dewar@adacore.com>
15782 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
15783 cases, pass the encoding method, since it is now required by the run
15786 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
15787 assumption that Str'First = 1.
15788 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
15789 it on to the Value_Wide_Wide_Character call.
15790 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
15791 properly handles a string of the form quote-encoded_wide_char-quote.
15793 * s-wchcnv.adb: Minor reformatting
15795 2006-10-31 Javier Miranda <miranda@adacore.com>
15797 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
15798 run-time membership test to ensure that the constructed object
15799 implements the target abstract interface.
15801 2006-10-31 Robert Dewar <dewar@adacore.com>
15803 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
15804 Machine_Attribute pragma internally to implement the user pragma.
15805 Add processing for pragma Interface so that it is now completely
15806 equivalent to pragma Import.
15808 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
15809 so that it can be applied to all entities, including record components
15810 and enumeration literals.
15811 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
15812 priority ranges are correct, verify compatibility against task
15813 dispatching and locking policies, and if everything is correct an entry
15814 is added to the table containing priority specific dispatching entries
15815 for this compilation unit.
15816 (Delay_Config_Pragma_Analyze): Delay processing
15817 Priority_Specific_Dispatching pragmas because when processing the
15818 pragma we need to access run-time data, such as the range of
15819 System.Any_Priority.
15820 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
15821 Allow pragma Unreferenced as a context item
15822 Add pragma Preelaborable_Initialization
15823 (Analyze_Pragma, case Interface): Interface is extended so that it is
15824 now syntactically and semantically equivalent to Import.
15825 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
15826 insertion characters.
15827 Add handling for Pragma_Wide_Character_Encoding
15828 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
15829 never supercedes a real restriction, and that a real restriction
15830 always supercedes a warning.
15831 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
15834 2006-10-31 Bob Duff <duff@adacore.com>
15835 Ed Schonberg <schonberg@adacore.com>
15836 Robert Dewar <dewar@adacore.com>
15838 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
15839 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
15840 Is_Inherently_Limited_Type, because return-by-reference has no meaning
15842 (Find_Node_To_Be_Wrapped): Use new method of determining the result
15843 type of the function containing a return statement, because the
15844 Return_Type field was removed. We now use the Return_Applies_To field.
15846 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
15847 (Build_Task_Image_Decl): If procedure is not called from an
15848 initialization procedure, indicate that function that builds task name
15849 uses the sec. stack. Otherwise the enclosing initialization procedure
15850 will carry the indication.
15851 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
15852 N_Object_Declaration instead.
15853 (Kill_Dead_Code): New interface to implement -gnatwt warning for
15854 conditional dead code killed, and change implementation accordingly.
15855 (Insert_Actions): Add N_Return_Object_Declaration case.
15856 Correct comment to mention N_Extension_Aggregate node.
15857 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
15858 attempts to save information for global variables which cannot be
15860 (Get_Current_Value_Condition): Handle conditions the other way round
15861 (constant on left). Also handle right operand of AND and AND THEN
15862 (Set_Current_Value_Condition): Corresponding changes
15863 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
15864 (Get_Current_Value_Condition): Handle simple boolean operands
15865 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
15866 (Get_Current_Value_Condition): If the variable reference is within an
15867 if-statement, does not appear in the list of then_statments, and does
15868 not come from source, treat it as being at unknown location.
15869 (Get_Current_Value_Condition): Enhance to allow while statements to be
15870 processed as well as if statements.
15871 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
15873 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
15874 of loop. This is safe now that we fixed Kill_Current_Values.
15875 (OK_To_Do_Constant_Replacement): Check whether current scope is
15876 Standard, before examining outer scopes.
15878 2006-10-31 Vincent Celier <celier@adacore.com>
15880 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
15881 When True, apply VMS treatment to children of packages A, G, I and S.
15884 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
15886 2006-10-31 Robert Dewar <dewar@adacore.com>
15887 Ed Schonberg <schonberg@adacore.com>
15889 * freeze.adb: Add handling of Last_Assignment field
15890 (Warn_Overlay): Supply missing continuation marks in error msgs
15891 (Freeze_Entity): Add check for Preelaborable_Initialization
15893 * g-comlin.adb: Add Warnings (Off) to prevent new warning
15895 * g-expect.adb: Add Warnings (Off) to prevent new warning
15897 * lib-xref.adb: Add handling of Last_Assignment field
15898 (Generate_Reference): Centralize handling of pragma Obsolescent here
15899 (Generate_Reference): Accept an implicit reference generated for a
15900 default in an instance.
15901 (Generate_Reference): Accept a reference for a node that is not in the
15902 main unit, if it is the generic body corresponding to an subprogram
15905 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
15907 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
15909 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
15911 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
15912 use clauses, to avoid messages on packages used to qualify, and also
15913 to avoid messages from obsolescent units.
15914 (Warn_On_Useless_Assignments): Don't generate messages for imported
15915 and exported variables.
15916 (Warn_On_Useless_Assignments): New procedure
15917 (Output_Obsolescent_Entity_Warnings): New procedure
15918 (Check_Code_Statement): New procedure
15920 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
15921 Change name Is_Ada_2005 to Is_Ada_2005_Only
15922 (Last_Assignment): New field for useless assignment warning
15924 2006-10-31 Olivier Hainque <hainque@adacore.com>
15926 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
15927 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
15929 2006-10-31 Bob Duff <duff@adacore.com>
15930 Robert Dewar <dewar@adacore.com>
15931 Ed Schonberg <schonberg@adacore.com>
15933 * g-awk.adb (Default_Session, Current_Session): Compile this file in
15934 Ada 95 mode, because it violates the new rules for AI-318.
15936 * g-awk.ads: Use overloaded subprograms in every case where we used to
15937 have a default of Current_Session. This makes the code closer to be
15938 correct for both Ada 95 and 2005.
15940 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
15941 code, relying on the fact that the compiler generates a warning
15942 instead of an error in -gnatg mode.
15944 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
15945 E_Return_Statement entity kind.
15946 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
15948 * par.adb (P_Interface_Type_Definition): Addition of one formal to
15949 report an error if the reserved word abstract has been previously found.
15950 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
15952 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
15953 parenthesized range attribute usage
15954 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
15956 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
15957 in the syntax for extended_return_statement. This is not in the latest
15958 RM, but the ARG is expected to issue an AI allowing this.
15959 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
15960 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
15961 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
15962 P_Return_Statement): Parse the new syntax for extended_return_statement.
15964 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
15965 Output_End_Missing): Add error-recovery code for the new
15966 extended_return_statement syntax; that is, the new E_Return entry on
15969 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
15970 limited to nonlimited, because otherwise we violate the new Ada 2005
15971 rules about returning limited types in function Create_AST_Handler in
15974 * sem.adb (Analyze): Add cases for new node kinds
15975 N_Extended_Return_Statement and N_Return_Object_Declaration.
15977 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
15978 type is in the same category as type of context before applying check,
15979 to prevent anomalies in instantiations.
15980 (Resolve_Aggregate): Remove test for limited components in aggregates.
15981 It's unnecessary in Ada 95, because if it has limited components, then
15982 it must be limited. It's wrong in Ada 2005, because limited aggregates
15984 (Resolve_Record_Aggregate): Move check for limited types later, because
15985 OK_For_Limited_Init requires its argument to have been resolved.
15986 (Get_Value): When copying the component default expression for a
15987 defaulted association in an aggregate, use the sloc of the aggregate
15988 and not that of the original expression, to prevent spurious
15989 elaboration errors, when the expression includes function calls.
15990 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
15991 were missing. We also didn't handle qualified expressions. Now also
15992 allow function calls. Use new common routine OK_For_Limited_Init.
15993 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
15994 with space can upper case letter).
15996 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
15997 Has_Static_Discriminants flag
15998 (Record_Type_Declaration): Diagnose an attempt to declare an interface
15999 type with discriminants.
16000 (Process_Range_Expr_In_Decl): Do validity checks on range
16001 (Build_Discriminant_Constraints): Use updated form of
16002 Denotes_Discriminant.
16003 (Process_Subtype): If the subtype is a private subtype whose full view
16004 is a concurrent subtype, introduce an itype reference to prevent scope
16006 (Build_Derived_Record_Type, Collect_Interface_Primitives,
16007 Record_Type_Declaration): The functionality of the subprograms
16008 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
16009 is now performed by a single routine.
16010 (Build_Derived_Record_Type): If the type definition includes an explicit
16011 indication of limitedness, then the type must be marked as limited here
16012 to ensure that any access discriminants will not be treated as having
16013 a local anonymous access type.
16014 (Check_Abstract_Overriding): Issue a detailed error message when an
16015 abstract subprogram was not overridden due to incorrect mode of its
16017 (Analyze_Private_Extension_Declaration): Add support for the analysis of
16018 synchronized private extension declarations. Verify that the ancestor is
16019 a limited or synchronized interface or in the generic case, the ancestor
16020 is a tagged limited type or synchronized interface and all progenitors
16021 are either limited or synchronized interfaces.
16022 Derived_Type_Declaration): Check for presence of private extension when
16023 dealing with synchronized formal derived types.
16024 Process_Full_View): Enchance the check done on the usage of "limited" by
16025 testing whether the private view is synchronized.
16026 Verify that a synchronized private view is completed by a protected or
16028 (OK_For_Limited_Init_In_05): New function.
16029 (Analyze_Object_Declaration): Move check for limited types later,
16030 because OK_For_Limited_Init requires its argument to have been resolved.
16031 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
16032 in order to alleviate the upward compatibility introduced by AI-318.
16033 (Constrain_Corresponding_Record): If the constraint is for a component
16034 subtype, mark the itype as frozen, to avoid out-of-scope references to
16035 discriminants in the back-end.
16036 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
16037 this subprogram against wrong sources.
16038 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
16039 discriminant of limited type completed with a protected type, when the
16040 discriminant is used to constrain a private component of the type, and
16041 expansion is disabled.
16042 (Find_Type_Of_Object): Do not treat a return subtype that is an
16043 anonymous subtype as a local_anonymous_type, because its accessibility
16044 level is the return type of the enclosing function.
16045 (Check_Initialization): In -gnatg mode, turn the error "cannot
16046 initialize entities of limited type" into a warning.
16047 (OK_For_Limited_Init): Return true for generated nodes, since it
16048 sometimes violates the legality rules.
16049 (Make_Incomplete_Declaration): If the type for which an incomplete
16050 declaration is created happens to be the currently visible entity,
16051 preserve the homonym chain when removing it from visibility.
16052 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
16053 inherited subprograms.
16054 (Access_Definition): If this is an access to function that is the return
16055 type of an access_to_function definition, context is a type declaration
16056 and the scope of the anonymous type is the current one.
16057 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
16058 incomplete subtype to the set of private dependents of the original
16060 (Constrain_Discriminated_Type): Emit an error message whenever an
16061 incomplete subtype is being constrained.
16062 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
16063 corresponding subtype of the full view of the original incomplete type.
16064 (Check_Incomplete): Properly detect invalid usage of incomplete types
16067 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
16069 * g-catiio.ads, g-catiio.adb (Value): New function.

16078 Robert Dewar <dewar@adacore.com>
16080 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
16081 handling executable extension manually and duplicating code.
16083 * make.adb: Implement new -S switch
16084 (Gnatmake): Use new function Osint.Executable_Name instead
16085 of handling executable extension manually.
16087 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
16088 is specified, the executable name ends with this suffix.
16089 Take advantage of Osint.Executable_Name instead of duplicating code.
16091 * switch-m.adb: Recognize new gnatmake -S switch
16093 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
16095 (Get_Target_Parameters): Set Executable_Extension_On_Target if
16098 * makeusg.adb: Add line for gnatmake -S switch
16100 2006-10-31 Vincent Celier <celier@adacore.com>
16102 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
16103 call it with -static-libgcc, as there are some platforms, such as
16104 Darwin, where one of these two switches is compulsory to link.
16106 2006-10-31 Vincent Celier <celier@adacore.com>
16108 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
16109 instead of ADA_PROJECT_PATH, for the project path.
16110 (Gnatls): When displaying the project path directories, use host dir
16113 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
16114 names in the project path, as absolute paths may correspond to
16115 multi-valued VMS logical names.
16117 2006-10-31 Vincent Celier <celier@adacore.com>
16119 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
16120 absolute path name.
16121 (Locate_Regular_File): Ditto
16122 (Change_Dir): Remove, no longer used
16123 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
16124 on Windows. Get it calling Get_Current_Dir.
16125 (OpenVMS): Remove imported boolean, no longer needed.
16126 (Normalize_Pathname)[VMS]: Do not resolve directory names.
16127 (Pid_To_Integer): New function to convert a Process_Id to Integer
16129 2006-10-31 Thomas Quinot <quinot@adacore.com>
16131 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
16132 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
16134 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
16137 2006-10-31 Robert Dewar <dewar@adacore.com>
16139 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
16140 initial letter o as a zero.
16142 2006-10-31 Robert Dewar <dewar@adacore.com>
16144 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
16146 2006-10-31 Robert Dewar <dewar@adacore.com>
16148 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
16150 (Layout_Variant_Record): Retrieve the discriminants from the entity
16151 rather than from the type definition, because in the case of a full
16152 type for a private type we need to take the discriminants from the
16154 (Layout_Component_List): When applying the Max operator to variants with
16155 a nonstatic size, check whether either operand is static and scale that
16156 operand from bits to storage units before applying Max.
16157 (Layout_Type): In VMS, if a C-convention access type has no explicit
16158 size clause (and does not inherit one in the case of a derived type),
16159 then the size is reset to 32 from 64.
16161 2006-10-31 Vincent Celier <celier@adacore.com>
16163 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
16164 its file has already been loaded, according to the unit being loaded,
16165 not to the current value of Multiple_Unit_Index.
16167 2006-10-31 Thomas Quinot <quinot@adacore.com>
16168 Eric Botcazou <ebotcazou@adacore.com>
16169 Arnaud Charlet <charlet@adacore.com>
16171 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
16172 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
16174 (a-except.o): Pass it to the compiler.
16175 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
16176 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
16177 a-calend-mingw.adb version.
16179 * Makefile.rtl: Added s-dsaser.
16180 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
16181 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
16182 Ada.Dispatching.Round_Robin.
16183 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
16185 * Make-lang.in: Remove all references to gt-ada-decl.h.
16186 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
16188 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
16189 Update dependencies.
16191 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
16193 2006-10-31 Vincent Celier <celier@adacore.com>
16195 * mlib-utl.adb (Initialized): Remove, no longer used
16196 (Initialize): Remove, no longer used
16197 (Ar): If Ar_Exec is null, get the location of the archive builder and,
16198 if there is one, the archive indexer. Fail if the archive builder cannot
16200 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
16203 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16205 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
16206 Process_Body_Clauses): If the context of a body includes a use clause
16207 for P.Q then a with_clause for P in the same body is not redundant,
16208 even if the spec also has a with_clause on P.
16209 Add missing continuation mark to error msg
16210 (Build_Limited_Views): A limited view of a type is tagged if its
16211 declaration includes a record extension.
16212 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
16213 node, even if the subunit has errors. This avoids malfunction by
16214 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
16215 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
16216 generation of obsolescent messages for with statements (cannot do
16217 this too early, or we cannot implement avoiding the messages in the
16218 case of obsolescent units withing obsolescent units).
16219 (Install_Siblings): If the with_clause is on a remote descendant of
16220 an ancestor of the current compilation unit, find whether there is
16221 a sibling child unit that is immediately visible.
16222 (Remove_Private_With_Clauses): New procedure, invoked after completing
16223 the analysis of the private part of a nested package, to remove from
16224 visibility the private with_clauses of the enclosing package
16226 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
16227 now centralized in Generate_Reference.
16228 (Install_Limited_Context_Clauses): Remove superfluous error
16229 message associated with unlimited view visible through use
16230 and renamings. In addition, at the point in which the error
16231 is reported, we add the backslash to the text of the error
16232 to ensure that it is reported as a single error message.
16233 Use new // insertion for some continuation messages
16234 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
16235 to create implicit with_clause for parent unit mentioned in original
16236 limited_with_clause.
16237 (Install_Limited_With_Unit): Set entity of parent identifiers if the
16238 unit is a child unit. For ASIS queries.
16239 (Analyze_Subunit): If the subunit appears within a child unit, make all
16240 ancestor child units directly visible again.
16242 2006-10-31 Robert Dewar <dewar@adacore.com>

16255 a formal object declaration with an access definition or a subtype mark
16256 with a null exclusion.
16257 (P_Generic_Association): Handle association with box, and others_choice
16258 with box, to support Ada 2005 partially parametrized formal packages.
16260 2006-10-31 Robert Dewar <dewar@adacore.com>
16261 Javier Miranda <miranda@adacore.com>
16263 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
16264 (P_Type_Declaration): Remove barrier against the reserved word "limited"
16265 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).

16267 private extensions.
16268 (P_Type_Declaration): Add the new actual Abstract_Present to every call
16269 to P_Interface_Type_Definition.
16270 (P_Interface_Type_Definition): Addition of one formal to report an error
16271 if the reserved word abstract has been previously found.
16272 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
16273 object renaming declaration with an access definition or subtype mark
16274 with a possible null exclusion.

16301 of sources, even if it is not the first time, as it is for another
16303 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
16304 dot, instead of replacing only the first '_'.
16306 * prj-part.adb (Parse): Convert project file path to canonical form
16308 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
16309 extended, the project id of the project extending it is recorded in its
16310 data, even when it has already been processed as an imported project.
16312 2006-10-31 Robert Dewar <dewar@adacore.com>
16314 * repinfo.adb (List_Entities): Don't list entities from renaming
16317 2006-10-31 Arnaud Charlet <charlet@adacore.com>
16318 Robert Dewar <dewar@adacore.com>
16320 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
16321 only a restriction warning is active for the given restriction. This is
16322 desirable because we do not want to modify code in the case where only
16324 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
16325 causes overriding of real restrictions.
16326 Take advantage of new No_Restrictions constant.
16328 * raise.h: (__gnat_set_globals): Change profile.
16330 2006-10-31 Arnaud Charlet <charlet@adacore.com>
16332 * rtsfind.adb: Remove s-polint from comment as it exists no more.
16335 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
16336 Move all the entities in obsolete package System.PolyORB_Interface to
16337 System.Partition_Interface.

16355 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
16356 properly an attempt to apply Unchecked_Access to a protected operation.
16357 (OK_Self_Reference): New subprogram to check the legality of an access
16358 attribute whose prefix is the type of an enclosing aggregate.
16359 Generalizes previous mechanism to handle attribute references nested
16360 arbitrarily deep within the aggregate.
16361 (Analyze_Access_Attribute): An access attribute whose prefix is a type
16362 can appear in an aggregate if this is a default-initialized aggregate
16363 for a self-referential type.
16364 (Resolve_Attribute, case Access): Ditto.
16365 Add support for new implementation defined attribute Stub_Type.
16366 (Eval_Attribute, case Attribute_Stub_Type): New case.
16367 (Analyze_Attribute, case Attribute_Stub_Type): New case.
16368 (Stream_Attribute_Available): Implement using new subprogram from
16369 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
16370 Has_Specified_Stream_Attribute flag.
16371 Disallow Storage_Size and Storage_Pool for access to subprogram
16372 (Resolve_Attribute, case 'Access et al): Take into account anonymous
16373 access types of return subtypes in extended return statements. Remove
16374 accessibility checks on anonymous access types when Unchecked_Access is
16376 (Analyze_Attribute): Add support for the use of 'Class to convert
16377 a class-wide interface to a tagged type.
16378 Add support for the attribute Priority.
16379 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
16380 whether the designated type is discriminated with a constrained partial
16381 view and require static matching in that case.
16382 Add local variable Des_Btyp. The Designated_Type
16383 of an access to incomplete subtype is either its non-limited view if
16384 coming from a limited with or its etype if regular incomplete subtype.
16386 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
16387 Fix predicate to identify and allow cases of (expander-generated)
16388 references to tag of designated object of a RACW.
16389 (Validate_Static_Object_Name): In Ada 2005, a formal object is
16390 non-static, and therefore cannot appear as a primary in a preelaborable
16392 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
16393 Has_Read_Write_Attributes.
16394 (Has_Read_Write_Attributes): Reimplement in termes of
16395 Has_Stream_Attribute_Definition.
16396 (Missing_Read_Write_Attributes): When checking component types in a
16397 record, unconditionally call Missing_Read_Write_Attributes recursively
16398 (remove guard checking for Is_Record_Type / Is_Access_Type).
16400 2006-10-31 Robert Dewar <dewar@adacore.com>
16402 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
16403 useless assignments here and conditionalize it on absence of exception
16405 (Analyze_Exception_Handlers): Small code reorganization of error
16406 detection code, for new handling of formal packages.
16408 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16409 Hristian Kirtchev <kirtchev@adacore.com>
16411 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
16412 that has been constant-folded, preserve information of original tree,
16414 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
16415 generated private extension declaration if the formal derived type is
16416 synchronized. Carry synchronized present over to the generated private
16418 (Validate_Derived_Type_Instance): Ensure that the actual of a
16419 synchronized formal derived type is a synchronized tagged type.
16420 (Instantiate_Formal_Package): When creating the instantiation used to
16421 validate the actual package of a formal declared without a box, check
16422 whether the formal itself depends on a prior actual.
16423 (Instantiate_Formal_Subprogram): Create new entities for the defining
16424 identifiers of the formals in the renaming declaration, for ASIS use.
16425 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
16426 a renaming declaration or a subtype declaration for an actual in an
16427 instance, capture location information of declaration in generic, for
16429 (Instantiate_Formal_Package): Add comments on needed additional tests.
16430 AI-317 (partial parametrization) is fully implemented.
16431 (Validate_Private_Type_Instance): Add check for actual which
16432 must have preelaborable initialization
16433 Use new // insertion for some continuation messages
16434 (Analyze_Formal_Object_Declaration): Change usage of Expression to
16435 Default_Expression. Add type retrieval when the declaration has an
16436 access definition. Update premature usage of incomplete type check.
16437 (Check_Access_Definition): New subsidiary routine. Check whether the
16438 current compilation version is Ada 05 and the supplied node has an
16440 (Instantiate object): Alphabetize local variables. Handle the creation
16441 of new renaming declarations with respect to the kind of definition
16442 used - either an access definition or a subtype mark. Guard against
16443 unnecessary error message in the context of anonymous access types after
16444 they have been resolved. Add check for required null exclusion in a
16445 formal object declaration.
16446 (Switch_View): A private subtype of a non-private type needs to be
16447 switched (the base type can have been switched without its private
16448 dependents because of the last branch of Check_Private_View.
16449 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
16451 (Instantiate_Type): Emit an error message whenever a class-wide type of
16452 a tagged incomplete type is used as a generic actual.
16453 (Find_Actual_Type): Extend routine to handle a component type in a child
16454 unit that is imported from a formal package in a parent.
16455 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
16456 agree on constrainedness, rather than checking against ultimate ancestor
16457 (Instantiate_Subprogram_Body): Create a cross-reference link to the
16458 generic body, for navigation purposes.
16460 2006-10-31 Robert Dewar <dewar@adacore.com>
16461 Thomas Quinot <quinot@adacore.com>
16463 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
16465 (New_Stream_Subprogram): When processing an attribute definition clause
16466 for a stream-oriented subprogram, record an entity node occurring at
16467 the point of clause to use for checking the visibility of the clause,
16468 as defined by 8.3(23) as amended by AI-195.
16469 (New_Stream_Subprogram): New procedure, factoring behaviour from both
16470 New_Stream_Function and New_Stream_Procedure.
16471 (New_Stream_Function, New_Stream_Procedure): Removed.
16472 (Analyze_Attribute_Definition_Clause, case Address): Check new
16473 Alignment_Check check
16475 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16476 Javier Miranda <miranda@adacore.com>
16477 Robert Dewar <dewar@adacore.com>
16479 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
16480 generate the same errors compiling under -gnatc.
16481 (Try_Object_Operation): If no candidate interpretation succeeds, but
16482 there is at least one primitive operation with the right name, report
16483 error in call rather than on a malformed selected component.
16484 (Analyze_Selected_Component): If the prefix is an incomplete type from
16485 a limited view, and the full view is available, use the full view to
16486 determine whether this is a prefixed call to a primitive operation.
16487 (Operator_Check): Verify that a candidate interpretation is a binary
16488 operation before checking the type of its second formal.
16489 (Analyze_Call): Add additional warnings for function call contexts not
16491 (Analyze_Allocator): Move the check for "initialization not allowed for
16492 limited types" after analyzing the expression. This is necessary,
16493 because OK_For_Limited_Init looks at the structure of the expression.
16494 Before analysis, we don't necessarily know what sort of expression it
16495 is. For example, we don't know whether F(X) is a function call or an
16496 indexed component; the former is legal in Ada 2005; the latter is not.
16497 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
16498 were missing. We also didn't handle qualified expressions. Now also
16499 allow function calls. Use new common routine OK_For_Limited_Init.
16500 (Analyze_Type_Conversion): Do not perform some legality checks in an
16501 instance, because the error message will be redundant or spurious.
16502 (Analyze_Overloaded_Selected_Component): Do not do style check when
16503 setting an entity, since we do not know it is the right entity yet.
16504 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
16505 (Analyze_Overloaded_Selected_Component): Same change
16506 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
16507 since regular incomplete subtypes are transformed into corresponding
16508 subtypes of their full views.
16509 (Complete_Object_Operation): Treat name of transformed subprogram call
16510 as coming from source, for browsing purposes.
16511 (Try_Primitive_Operation): If formal is an access parameter, compare
16512 with base type of object to determine whether it is a primitive
16514 (Operator_Check): If no interpretation of the operator matches, check
16515 whether a use clause on any candidate might make the operation legal.
16516 (Try_Class_Wide_Operation): Check whether the first parameter is an
16517 access type whose designated type is class-wide.

16524 warn on infinite loops.
16525 Add \\ to some continuation messages
16526 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
16527 (Process_Bounds): If the bounds are integer literals that result from
16528 constant-folding, and they carry a user-defined type, preserve that type
16529 rather than treating this as an integer range.
16530 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
16531 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
16532 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
16533 left hand side of assignment.
16534 (Analyze_Assignment): Add suport to manage assigments to the attribute
16535 priority of a protected object.
16536 (Check_Possible_Current_Value_Condition): Allow fully qualified names
16537 not just identifiers.
16538 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
16539 or AND THEN for possible tracking.
16540 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
16541 case of while loops so we can track values in the loop body.
16543 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16544 Hristian Kirtchev <kirtchev@adacore.com>
16545 Bob Duff <duff@adacore.com>
16547 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
16548 procedure cannot be a protected operation (it is a basic_declaration,
16549 not a subprogram_declaration).
16550 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
16551 Subp. Add logic for entry processing.
16552 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
16553 Determine whether an entry or subprogram of a protected or task type
16554 override an inherited primitive of an implemented interface.
16555 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
16556 Update the actual used in calls to Check_Overriding_Indicator.
16557 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
16558 generate the proper reference to the parent unit, for cross-reference.
16559 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
16561 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
16562 (Add_Extra_Formal): Revise procedure to allow passing in associated
16563 entity, scope, and name suffix, and handle setting of the new
16564 Extra_Formals field.
16565 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
16566 pass new parameters. Add support for adding the new extra access formal
16567 for functions whose calls are treated as build-in-place.
16568 (Analyze_A_Return_Statement): Correct casing in error message.
16569 Move Pop_Scope to after Analyze_Function_Return, because an extended
16570 return statement really is a full-fledged scope. Otherwise, visibility
16571 doesn't work right. Correct use of "\" for continuation messages.
16572 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
16573 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
16574 the node doesn't get properly marked as analyzed.
16575 (Analyze_Subprogram_Body): If subprogram is a function that returns
16576 an anonymous access type that denotes a task, build a Master Entity
16578 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
16579 proper usage of null exclusion in a result definition.
16580 (Process_Formals): Code cleanup and new error message.
16581 (Process_Formals): Detect incorrect application of null exclusion to
16583 (Conforming_Types): Handle conformance between [sub]types and itypes
16584 generated for entities that have null exclusions applied to them.
16585 (Maybe_Primitive_Operation): Add an additional type retrieval when the
16586 base type is an access subtype. This case arrises with null exclusions.
16587 (New_Overloaded_Entity): Do not remove the overriden entity from the
16588 homonym chain if it corresponds with an abstract interface primitive.
16589 (Process_Formals): Replace membership test agains Incomplete_Kind with a
16590 call to the synthesized predicate Is_Incomplete_Type.
16591 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
16593 (Analyze_Subprogram_Declaration): Check that abstract interface
16594 primitives are abstract or null.
16595 (Analyze_Subprogram_Specification): Remove previous check for abstract
16596 interfaces because it was not complete.
16597 (Has_Interface_Formals): Removed.
16599 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16600 Javier Miranda <miranda@adacore.com>
16602 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
16603 of Analyze_Package_Body, to create Itype references for anonymous
16604 access types created in the package declaration, whose designated types
16605 may have only a limited view.
16606 (Analyze_Package_Specification): For the private part of a nested
16607 package, install private_with_clauses of enclosing compilation unit if
16608 we are in its visible part.
16609 (Declare_Inherited_Private_Subprograms): Complete barrier
16610 to ensure that the primitive operation has an alias to some parent
16611 primitive. This is now required because, after the changes done for the
16612 implementation of abstract interfaces, the contents of the list of
16613 primitives has entities whose alias attribute references entities of
16614 such list of primitives.
16615 (Analyze_Package_Specification): Simplify code that handles parent units
16616 of instances and formal packages.
16617 (Uninstall_Declarations): Check the convention consistency among
16618 primitive overriding operations of a tagged record type.
16620 2006-10-31 Robert Dewar <dewar@adacore.com>

16627 expected and found set right)
16628 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
16629 (Analyze_Generic_Renaming): Same fix
16630 (Use_One_Package): Do not take into account the internal entities of
16631 abstract interfaces during the analysis of entities that are marked
16632 as potentially use-visible.
16633 (Find_Type): Handle the case of an attribute reference for
16634 implementation defined attribute Stub_Type (simply let the analysis of
16635 the attribute reference rewrite it).
16636 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
16637 type that appears in a Use_Type clause.
16638 (Analyze_Object_Renaming): Add support for renaming of the Priority
16640 (Find_Type): In Ada 2005, a task type can be used within its own body,
16641 when it appears in an access definition.
16642 (Analyze_Object_Renaming): Remove warning on null_exclusion.
16643 (Analyze_Object_Renaming): Introduce checks for required null exclusion
16644 in a formal object declaration or in a subtype declaration.
16645 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
16646 (Check_Null_Exclusion): New local routine to
16647 Analyze_Subprogram_Renaming. Check whether the formals and return
16648 profile of a renamed subprogram have required null exclusions when
16649 their counterparts of the renaming already impose them.
16650 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
16651 Determine whether an entity is inside a generic scope.
16652 (In_Open_Scope): First pass of documentation update.
16653 (Find_Expanded_Name): Add support for shadow entities associated with
16654 limited withed packages. This is required to handle nested packages.
16655 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
16656 that makes a renaming of a limited withed package illegal.

16661 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
16662 Check_Overriding_Indicator.
16663 (Analyze_Task_Definition): Ditto.
16664 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
16665 (Check_Overriding_Indicator): To find overridden interface operation,
16666 examine only homonyms that have an explicit subprogram declaration, not
16667 inherited operations created by an unrelated type derivation.
16668 (Check_Overriding_Indicator): When checking for the presence of "null"
16669 in a procedure, ensure that the queried node is a procedure
16671 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
16672 type when the formal is an access to variable.
16673 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
16674 (Analyze_Task_Type): Same addition
16675 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
16676 provide navigation capabilities for entries.

16683 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
16684 inherited from an interface ancestor by another interface in the
16685 context of an instance as 'late'.
16686 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
16687 of a call to a function that dispatches on access result.
16688 (Check_Dispatching_Operation): In case of late overriding of a primitive

17516 we must pass the work to the expander to generate the required code to
17517 evaluate the conversion at run-time.
17518 (Resolve_Equality_Op): Do not apply previous

18140 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>
18142 * s-stchop.adb (Stack_Check): Raise Storage_Error if the argument has

18156 Thomas Quinot <quinot@adacore.com>
18158 * checks.adb (Build_Discriminant_Checks): If the expression being
18159 checks is an aggregate retrieve the values of its discriminants to
18160 generate the check, rather than creating a temporary and a reference
18162 (Apply_Access_Check): Rewritten to handle new Is_Known_Null flag
18163 (Install_Null_Excluding_Check): Ditto
18164 (Selected_Length_Checks): Build actual subtype for the original Ck_Node,

18180 * switch.ads, switch.adb (Bad_Switch): New procedure
18182 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
18183 Remove 0-9 as debug flag character possibilities
18184 -d is now controlling the primary stack size when its value is a
18185 positive. Also add checks against invalid values, and support for kb,
18186 mb. Ditto for -D switch.
18188 2006-02-13 Robert Dewar <dewar@adacore.com>
18189 Serguei Rybin <rybin@adacore.com>
18191 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
18192 save/restore routines.
18193 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18194 were not always properly handled previously.
18195 Since we are changing the tree format anyway, also get rid of the
18196 junk obsolete Immediate_Errors flag.
18197 (Tree_Read): Change the way of reading Tree_Version_String - now we
18198 read the version string from the tree even if its length is not the
18199 same as the length of the version string computed from Gnatvsn.
18200 (Search_Directory_Present): New Boolean flag for the compiler.
18201 Define Tree_Version_String as a dynamic string.
18202 (Default_Stack_Size): new variable, used to handle switch -d.
18205 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
18206 only for main unit.
18207 Add pragma Ada_2005 (synonym for Ada_05)
18208 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18209 were not always properly handled previously.
18211 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
18212 explicit Ada_95 to Ada_2005.
18214 2006-02-13 Javier Miranda <miranda@adacore.com>
18215 Robert Dewar <dewar@adacore.com>
18216 Ed Schonberg <schonberg@adacore.com>
18218 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
18219 against errors in the source program: a private types for which the
18220 corresponding full type declaration is missing and pragma CPP_Virtual
18222 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
18223 (Is_Known_Null): New flag
18224 (Has_Pragma_Pure): New flag
18225 (No_Return): Present in all entities, set only for procedures
18226 (Is_Limited_Type): A type whose ancestor is an interface is limited if
18227 explicitly declared limited.
18228 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
18229 entities. Only used for component marked Is_Tag. If present it stores
18230 the Offset_To_Top function used to provide this value in tagged types
18231 whose ancestor has discriminants.
18233 * exp_ch2.adb: Update status of new Is_Known_Null flag
18235 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
18237 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
18238 the categorization sense if Is_Pure was set by pragma Pure_Function.
18240 2006-02-13 Quentin Ochem <ochem@adacore.com>
18241 Olivier Hainque <hainque@adacore.com>
18243 * bindusg.adb: Updated documentation for -d and -D switches.
18245 * raise.h (__gnat_set_globals): added new parameter for
18246 Default_Stack_Size.
18248 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
18249 (__gnat_handle_vms_condition): Adjust context before raise.
18250 (__gnat_install_handler): Restore the global vector setup for GCC
18251 versions before 3.4, as the frame based circtuitry is not available
18253 (__gnat_set_globals): added a parameter default_stack_size
18254 (__gl_default_stack_size): new variable.
18256 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18258 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
18259 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
18260 does not exist in the Ada RM.
18261 (Compatible_Int_Bounds): Determine whether two integer range bounds
18262 are of equal length and have the same start and end values.
18263 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
18264 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
18265 aggregate when it is part of an object declaration.
18266 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
18267 constrains discriminants of its parent, add explicitly the discriminant
18268 constraints of the ancestor by retrieving them from the
18269 stored_constraint of the parent.
18271 2006-02-13 Robert Dewar <dewar@adacore.com>
18273 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
18274 attribute Mechanism_Code is applied to renamed subprogram, modify
18275 prefix to point to base subprogram.
18276 Max/Min attributes now violate Restriction No_Implicit_Conditionals
18278 * sinfo.ads: Document that Mechanism_Code cannot be applied to
18279 renamed subprograms so that the front-end must replace the prefix
18282 2006-02-13 Javier Miranda <miranda@adacore.com>
18283 Gary Dismukes <dismukes@adacore.com>
18285 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
18286 availability of RE_Interface_Tag.
18287 (Build_Initialization_Call): Fix wrong access to the discriminant value.
18288 (Freeze_Record_Type): Do not generate the tables associated with
18289 timed and conditional dispatching calls through synchronized
18290 interfaces if compiling under No_Dispatching_Calls restriction.
18291 When compiling for Ada 2005, for a nonabstract
18292 type with a null extension, call Make_Controlling_Function_Wrappers
18293 and insert the wrapper function declarations and bodies (the latter
18294 being appended as freeze actions).
18295 (Predefined_Primitive_Bodies): Do not generate the bodies of the
18296 predefined primitives associated with timed and conditional
18297 dispatching calls through synchronized interfaces if we are
18298 compiling under No_Dispatching_Calls.
18299 (Build_Init_Procedure): Use RTE_Available to check if a run-time
18300 service is available before generating a call.
18301 (Make_Controlling_Function_Wrappers): New procedure.
18302 (Expand_N_Full_Type_Declaration): Create a class-wide master for
18303 access-to-limited-interfaces because they can be used to reference
18304 tasks that implement such limited interface.
18305 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
18306 procedure spec and body of the Offset_To_Top function that is generated
18307 when the parent of a type with discriminants has secondary dispatch
18309 (Init_Secondary_Tags): Handle the case in which the parent of the type
18310 containing secondary dispatch tables has discriminants to generate the
18311 correct arguments to call Set_Offset_To_Top.
18312 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
18314 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
18315 Add Wide_[Wide_]Expanded_Name.
18316 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
18317 the same functionality of Get_Prim_Op_Address but applied to predefined
18318 primitive operations because the pointers to the predefined primitives
18319 are now saved in a separate table.
18320 (Parent_Size): Modified to get access to the separate table of primitive
18321 operations or the parent type.
18322 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
18323 functionality of Set_Prim_Op_Address but applied to predefined primitive
18325 (Set_Signature): New subprogram used to store the signature of a DT.
18326 (Displace): If the Offset_To_Top value is not static then call the
18327 function generated by the expander to get such value; otherwise use
18328 the value stored in the table of interfaces.
18329 (Offset_To_Top): The type of the actual has been changed to Address to
18330 give the correct support to tagged types with discriminants. In this
18331 case this value is stored just immediately after the tag field.
18332 (Set_Offset_To_Top): Two new formals have been added to indicate if the
18333 offset_to_top value is static and hence pass this value to the run-time
18334 to store it in the table of interfaces, or else if this value is dynamic
18335 and then pass to the run-time the address of a function that is
18336 generated by the expander to provide this value for each object of the
18339 * rtsfind.ads (Default_Prin_Op_Count): Removed.
18340 (Default_Prim_Op_Count): New entity
18341 (Get_Predefined_Prim_Op_Address): New entity
18342 (Set_Predefined_Prim_Op_Address): New entity
18343 (RE_Set_Signature): New entity

18346 Ed Schonberg <schonberg@adacore.com>
18348 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
18349 Make_Adjust_Call done for a newly-allocated object.
18351 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
18352 in a subprogram are wrapped in a cleanup block, indicate that the
18353 subprogram contains an inner block with an exception handler.
18354 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
18355 Adjust call is for a newly-allocated object. In that case we must not
18356 assume that the finalization list chain pointers are correct (since they
18357 come from a bit-for-bit copy of the original object's pointers) so if
18358 the attach level would otherwise be zero (no change), we set it to 4
18359 instead to cause the pointers to be reset to null.
18361 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
18362 reset chain pointers to null.
18364 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18366 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
18367 string, and the context requires a loop for the assignment (e.g.
18368 because the left-hand side is packed), generate a unique name for the
18369 temporary that holds the string, to prevent spurious name clashes.
18371 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18372 Javier Miranda <miranda@adacore.com>
18373 Robert Dewar <dewar@adacore.com>
18374 Gary Dismukes <dismukes@adacore.com>
18376 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
18377 return unconstrained arrays.
18379 (Expand_Call): An indirect call through an access parameter of a
18380 protected operation is not a protected call.
18381 Add circuit to raise CE in Ada 2005 mode following call
18382 to Raise_Exception.
18383 (Register_DT_Entry): Do nothing if
18384 the run-time does not give support to abstract interfaces.
18385 (Freeze_Subprogram): In case of dispatching operations, do not generate
18386 code to register the operation in the dispatch table if the source
18387 is compiled with No_Dispatching_Calls.
18388 (Register_Predefined_DT_Entry): Generate code that calls the new
18389 run-time subprogram Set_Predefined_Prim_Op_Address instead of
18390 Set_Prim_Op_Address.
18392 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
18393 on array assignments if the right-hand side is a function call that has
18394 been inlined. Check is performed on the assignment in the block.
18395 (Process_Bounds): If bounds and range are overloaded, apply preference
18396 rule for root operations to disambiguate, and diagnose true ambiguity.
18397 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
18398 a tag-indeterminate right-hand side even when Expander_Active is True.
18399 Needed to ensure that dispatching calls to T'Input are allowed and
18400 get the tag of the target class-wide object.
18402 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
18403 an inherited primitive operation that already overrides several
18404 abstract interface primitives. For transitivity, the new entity must
18405 also override all the abstract interface primitives covered by the
18406 inherited overriden primitive.
18407 Emit warning if new entity differs from homograph in same scope only in
18408 that one has an access parameter and the other one has a parameter of
18409 a general access type with the same designated type, at the same
18410 position in the signature.
18411 (Make_Inequality_Operator): Use source locations of parameters and
18412 subtype marks from corresponding equality operator when creating the
18413 tree structure for the implicit declaration of "/=". This does not
18414 change anything in behaviour except that the decoration of the
18415 components of the subtree created for "/=" allows ASIS to get the
18416 string images of the corresponding identifiers.
18417 (Analyze_Return_Statement): Remove '!' in warning message.
18418 (Check_Statement_Sequence): Likewise.
18419 (Analyze_Subprogram_Body): For an access parameter whose designated type
18420 is an incomplete type imported through a limited_with clause, use the
18421 type of the corresponding formal in the body.
18422 (Check_Returns): Implicit return in No_Return procedure now raises
18423 Program_Error with a compile time warning, instead of beging illegal.
18424 (Has_Single_Return): Function returning unconstrained type cannot be
18425 inlined if expression in unique return statement is not an identifier.
18426 (Build_Body_To_Inline): It is possible to inline a function call that
18427 returns an unconstrained type if all return statements in the function
18428 return the same local variable. Subsidiary procedure Has_Single_Return
18429 verifies that the body conforms to this restriction.
18431 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
18432 same type, and one of them is of an anonymous access type, convert
18433 the other operand to it, so that this is a valid binary operation for
18435 (Resolve_Type_Conversion): Handle subtypes of protected types and
18436 task types when accessing to the corresponding record type.
18437 (Resolve_Allocator): Add '\' in 2-line warning message.
18438 Remove '!' in warning message.
18439 (Resolve_Call): Add '\' in 2-line warning message.
18440 (Valid_Conversion): Likewise.
18441 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
18442 resulting type may be an access type with an implicit dereference.
18443 Obtain the proper component from the designated type.
18444 (Make_Call_Into_Operator): Handle properly a call to predefined equality
18445 given by an expanded name with prefix Standard, when the operands are
18446 of an anonymous access type.
18447 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
18448 Explicit_Dereference and Resolve_Selected_Component, to verify that the
18449 prefix of the expression is not of an incomplete type. Allows full
18450 diagnoses of all semantic errors.
18451 (Resolve_Actuals): If the actual is an allocator whose directly
18452 designated type is a class-wide interface we build an anonymous
18453 access type to use it as the type of the allocator. Later, when
18454 the subprogram call is expanded, if the interface has a secondary
18455 dispatch table the expander will add a type conversion to force
18456 the displacement of the pointer.
18457 (Resolve_Call): If a function that returns an unconstrained type is
18458 marked Inlined_Always and inlined, the call will be inlined and does
18459 not require the creation of a transient scope.
18460 (Check_Direct_Boolean_Op): Removed
18461 (Resolve_Comparison_Op): Remove call to above
18462 (Resolve_Equality_Op): Remove call to above
18463 (Resolve_Logical_Op): Inline above, since this is only call.
18464 (Valid_Conversion): Handle properly conversions between arrays of
18465 convertible anonymous access types.
18468 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
18469 the literal in an unchecked conversion, because GCC 4.x needs a static
18470 value for a string bound.
18472 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18473 Hristian Kirtchev <kirtchev@adacore.com>
18475 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
18476 components of the corresponding record, take into account component
18477 definitions that are access definitions.
18478 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
18479 procedure is not considered a dispatching call and will be expanded
18482 2006-02-13 Javier Miranda <miranda@adacore.com>
18484 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
18485 controlling argument of the dispatching call is an abstract interface
18486 class-wide type then we use it directly.
18487 Check No_Dispatching_Calls restriction.
18488 (Default_Prim_Op_Position): Remove the code that looks for the last
18489 entity in the list of aliased subprograms. This code was wrong in
18491 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
18492 when the source is compiled with the No_Dispatching_Calls restriction.
18493 (Init_Predefined_Interface_Primitives): No need to inherit primitives
18494 if we are compiling with restriction No_Dispatching_Calls.
18495 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
18496 subprograms if we are compiling under No_Dispatching_Calls restriction.
18497 (Make_DT): Generate a dispatch table with a single dummy entry if
18498 we are compiling with the No_Dispatching_Calls restriction. In
18499 addition, in this case we don't generate code that calls to the
18500 following run-time subprograms: Set_Type_Kind, Inherit_DT.
18501 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
18502 of this subprogram if compiling with the No_Dispatching_Calls
18504 (Expand_Type_Conversion): Instead of using the actual parameter,
18505 the argument passed as parameter to the conversion function was
18506 erroneously referenced by the expander.
18507 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
18508 Set_Predefined_Primitive_Op_Address and Set_Signature.
18509 (Expand_Dispatching_Call): Generate call to
18510 Get_Predefined_Prim_Op_Address for predefined primitives.
18511 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
18512 predefined primitives.
18513 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
18514 primitives we reserve one dummy entry to ensure that the tag does not
18515 point to some memory that is associated with some other object. In
18516 addition, remove all the old code that generated the assignments
18517 associated with the signature of the dispatch table and replace them
18518 by a call to the new subprogram Set_Signature.
18519 (Set_All_DT_Position): Change the algorithm because now we have a
18520 separate dispatch table associated with predefined primitive operations.
18521 (Expand_Interface_Conversion): In case of non-static offset_to_top
18522 add explicit dereference to get access to the object after the call
18523 to displace the pointer to the object.
18524 (Expand_Interface_Thunk): Modify the generation of the actual used
18525 in the calls to the run-time function Offset_To_Top to fulfil its
18527 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
18529 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18531 * exp_dist.adb (Copy_Specification): For access parameters, copy
18532 Null_Exclusion flag, which will have been set for stream subprograms
18535 2006-02-13 Pascal Obry <obry@adacore.com>
18537 * expect.c (__gnat_expect_portable_execvp): New implementation. The
18538 previous implementation was using the C runtime spawnve routine but
18539 the corresponding wait was using directly the Win32 API. This was
18540 causing some times a lock when waiting for an event using
18541 WaitForSingleObject in __gnat_waitpid. This new implementation uses
18542 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
18543 API fixes this problem.
18545 2006-02-13 Robert Dewar <dewar@adacore.com>
18547 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

18552 * exp_pakd.ads: Fix typos in comments.
18554 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
18555 array reference that is an explicit dereference, mark the converted
18556 (packed) array reference as analyzed to prevent a forthcoming
18557 reanalysis from resetting its type to the original (non-packed) array

18561 Javier Miranda <miranda@adacore.com>
18562 Eric Botcazou <ebotcazou@adacore.com>
18564 * exp_util.ads, exp_util.adb (Find_Prim_Op,
18565 Is_Predefined_Primitive_Operation): When
18566 searching for the predefined equality operator, verify that operands
18567 have the same type.
18568 (Is_Predefined_Dispatching_Operation): Remove the code that looks
18569 for the last entity in the list of aliased subprograms. This code
18570 was wrong in case of renamings.
18571 (Set_Renamed_Subprogram): New procedure
18572 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
18573 Exp_Type constant computed when entering this subprogram.
18574 (Known_Null): New function
18575 (OK_To_Do_Constant_Replacement): New function
18576 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
18577 (Side_Effect_Free): An attribute reference 'Input is not free of
18578 side effect, unlike other attributes that are functions. (from code
18580 (Remove_Side_Effects): Expressions that involve packed arrays or records
18581 are copied at the point of reference, and therefore must be marked as
18582 renamings of objects.
18583 (Is_Predefined_Dispatching_Operation): Return false if the operation is
18584 not a dispatching operation.
18587 (Remove_Side_Effects): Lift enclosing type conversion nodes for
18588 elementary types in all cases.
18590 2006-02-13 Javier Miranda <miranda@adacore.com>
18592 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and

18594 Remove '!' in warning message.
18596 2006-02-13 Olivier Hainque <hainque@adacore.com>
18598 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
18599 to avoid useless and space inefficient overalignments on targets where
18600 Max_Alignment is larger than 16.
18602 2006-02-13 Pascal Obry <obry@adacore.com>
18604 * g-catiio.adb (Sec_Number): New type used to compute the number of
18605 seconds since 1-1-1970.
18606 (Image) [Natural]: The parameter was an Integer, as we can't deal with
18607 negative numbers (years, months...) it is better to have a Natural here.
18609 (Image) [Number]: Change parameter from Long_Integer to Number.
18610 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
18611 overflow for dates past year 2038.
18613 2006-02-13 Matthew Heaney <heaney@adacore.com>
18615 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise

18620 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
18622 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that

18627 * gnatcmd.adb (Rules_Switches): New table
18628 (Add_To_Rules_Switches): New procedure
18629 (GNATCmd): For command CHECK, put all options following "-rules" in the
18630 Rules_Switches table. Append these -rules switches after the -cargs
18633 2006-02-13 Robert Dewar <dewar@adacore.com>
18635 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
18636 These two cases were generating incorrect output, and if this unit
18637 was built with checks on, generated a discriminant mismatch constraint
18640 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18641 Robert Dewar <dewar@adacore.com>
18643 * lib-xref.adb (Get_Type_Reference): For a private type whose full
18644 view is an array type, indicate the component type as well, for
18645 navigation purposes.
18646 (Generate_Reference): Don't consider array ref on LHS to be a case
18647 of violating pragma Unreferenced.
18648 Do not give Ada 2005 warning except on real reference.
18650 2006-02-13 Vincent Celier <celier@adacore.com>
18652 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
18653 main source, add switch -mdebug-main=_ada_ so that the executable can
18654 be debugged by the standard VMS debugger.
18655 (Gnatmake): Set No_Main_Subprogram to True when there is no main
18656 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
18657 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
18658 of the last source, as the binding and linking phases are never
18660 Set all executable obsolete when rebuilding a library.
18662 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
18665 2006-02-13 Javier Miranda <miranda@adacore.com>
18668 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
18669 code to improve the error message reported when the program has
18670 declarations of abstract interface types and it is not compiled with
18671 the -gnat05 switch.
18672 (P_Access_Definition): Reorganize the code to improve the error
18673 message reported when the new Ada 2005 syntax for anonymous
18674 access types is used and the program is not compiled with the
18677 2006-02-13 Robert Dewar <dewar@adacore.com>
18679 * par-ch6.adb, style.ads, styleg.adb, styleg.ads, stylesw.adb,

18683 2006-02-13 Javier Miranda <miranda@adacore.com>
18685 * par-endh.adb (Explicit_Start_Label): Add code to protect the parser
18686 against source containing syntax errors.
18688 2006-02-13 Vincent Celier <celier@adacore.com>

18697 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
18698 unknown, use the location of the project to report the error.
18699 (When_No_Sources): New global variable
18700 (Report_No_Ada_Sources): New procedure
18701 (Check): New parameter When_No_Sources. Set value of global variable
18703 (Find_Sources): Call Report_No_Ada_Sources when appropriate
18704 (Get_Sources_From_File): Ditto
18705 (Warn_If_Not_Sources): Better warning messages indicating the unit name
18708 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
18709 Call Prj.Proc.Process with parameter When_No_Sources.
18711 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
18712 Call Recursive_Check with parameter When_No_Sources.
18713 (Recursive_Check): New parameter When_No_Sources. Call itself and
18714 Prj.Nmsc.Check with parameter When_No_Sources.
18715 (Process): New parameter When_No_Sources. Call Check with parameter
18717 (Copy_Package_Declarations): New procedure to copy renamed parameters
18718 and setting the location of the declared attributes to the location
18719 of the renamed package.

18725 * prj-makr.adb (Make): Preserve the comments from the original project
18727 When removing nodes (attributes Source_Dirs, Source_Files,
18728 Source_List_File and package Naming), save the comments and attach the
18729 saved comments to the newly created nodes.
18730 Do not add a with clause for the naming package if one already exists.
18732 2006-02-13 Javier Miranda <miranda@adacore.com>
18733 Gary Dismukes <dismukes@adacore.com>
18734 Robert Dewar <dewar@adacore.com>

18738 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
18739 aliased entities to look for the overriden abstract interface
18741 (Is_Interface_Subprogram): Complete documentation.
18742 (Check_Dispatching_Operation): Do not generate code to register the
18743 operation in the dispatch table if the source is compiled with
18744 restriction No_Dispatching_Calls.
18745 (Override_Dispatching_Operation): Check for illegal attempt to override
18746 No_Return procedure with procedure that is not No_Return
18747 (Check_Dispatching_Call): Suppress the check for an abstract operation
18748 when the original node of an actual is a tag-indeterminate attribute
18749 call, since the attribute, which must be 'Input, can never be abstract.
18750 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
18751 call to the Input attribute (even when rewritten).
18752 (Propagate_Tag): Augment comment to indicate the possibility of a call
18753 to an Input attribute.
18755 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
18756 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
18758 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
18759 No_Wide_Characters is no longer partition-wide
18760 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
18763 2006-02-13 Douglas Rupp <rupp@adacore.com>
18765 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
18767 2006-02-13 Javier Miranda <miranda@adacore.com>
18769 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
18770 handles default-initialized components to keep separate the management
18771 of this feature but also avoid the unrequired resolution and
18772 expansion of components that do not have partially initialized
18774 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
18775 (Check_Bounds): Likewise.
18776 (Check_Length): Likewise.
18778 2006-02-13 Javier Miranda <miranda@adacore.com>
18779 Ed Schonberg <schonberg@adacore.com>
18781 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
18782 abstract interface type call analyze_and_resolve to expand the type
18783 conversion into the corresponding displacement of the
18784 reference to the base of the object.
18785 (Eval_Attribute, case Width): For systems where IEEE extended precision
18786 is supported, the maximum exponent occupies 4 decimal digits.
18787 (Accessibility_Message): Add '\' in 2-line warning message.
18788 (Resolve_Attribute): Likewise.
18789 (case Attribute_Access): Significantly revise checks
18790 for illegal access-to-subprogram Access attributes to properly enforce
18791 the rules of 3.10.2(32/2).
18792 Diagnose use of current instance with an illegal attribute.
18794 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
18796 (Enclosing_Generic_Unit): New function to return a node's innermost
18797 enclosing generic declaration node.
18798 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
18799 (Type_Access_Level): The accessibility level of anonymous acccess types
18800 associated with discriminants is that of the current instance of the
18801 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
18802 (Compile_Time_Constraint_Error): Handle case of conditional expression.
18803 (Kill_Current_Values_For_Entity): New function
18804 (Enter_Name): Change formal type to Entity_Id
18806 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
18807 Ed Schonberg <schonberg@adacore.com>
18808 Gary Dismukes <dismukes@adacore.com>
18810 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
18811 Analyze_Compilation_Unit.
18812 Detect and warn on redundant with clauses detected in a package spec
18813 and/or body when -gnatwr is used.
18814 (Analyze_Context): Analyze config pragmas before other items
18815 (Install_Context_Items): Don't analyze config pragmas here
18816 (Install_Limited_Withed_Unit): Set limited entity of package in
18817 with_clause so that cross-reference information or warning messages on
18818 unused packages can be properly generated
18819 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
18820 has Error_Posted set. Prevent infinite loops in illegal programs.
18821 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
18822 to the point of the error test requiring the current unit to be private.
18823 This ensures that private with clauses are not exempted from the basic
18824 checking for being a descendant of the same library unit parent as a
18825 withed private descendant unit.
18826 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
18827 handle private with clauses properly, as well as to account for cases
18828 where the withed unit is a public descendant of a private ancestor
18829 (in which case the current unit must be a descendant of the private
18830 ancestor's parent). The spec comments were updated accordingly. Also,
18831 the old error message in this subprogram was replaced with error
18832 messages that mirror the errors tested and reported by
18833 Check_Private_Child_Unit.
18834 Parameter and variable names improved for readability.
18835 (Install_Limited_Context_Clauses): Remove test for a withed unit being
18836 private as the precondition for calling
18837 Check_Private_Limited_Withed_Unit since that subprogram has been
18838 revised to test public units as well as private units.

18841 Robert Dewar <dewar@adacore.com>
18842 Ed Schonberg <schonberg@adacore.com>
18843 Javier Miranda <miranda@adacore.com>
18845 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
18846 that Scope_Stack.First = 1.
18847 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18848 were not always properly handled previously.
18849 (Formal_Entity): Complete rewrite, to handle properly some complex case
18850 with multiple levels of parametrization by formal packages.
18851 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
18852 to the corresponding derived type declaration for proper semantics.
18854 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
18855 (Check_Component): Enforce restriction on components of
18856 unchecked_unions: a component in a variant cannot contain tasks or
18858 (Unchecked_Union): Allow nested variants and multiple discriminants, to
18860 Add pragma Ada_2005 (synonym for Ada_05)
18861 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18862 were not always properly handled previously.
18863 Document that pragma Propagate_Exceptions has no effect
18864 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
18865 (Set_Convention_From_Pragma): Check that if a convention is
18866 specified for a dispatching operation, then it must be
18867 consistent with the existing convention for the operation.
18868 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
18869 longer required to specify an vtable-ptr component in the record. For
18870 compatibility reasons we leave the support for the previous definition.
18871 (Analyze_Pragma, case No_Return): Allow multiple arguments
18873 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
18874 non-overrideen inherited operation with a controlling result as
18875 illegal only its implicit declaration comes from the derived type
18876 declaration of its result's type.
18877 (Check_Possible_Deferred_Completion): Relocate the object definition
18878 node of the subtype indication of a deferred constant completion rather
18879 than directly analyzing it. The analysis of the generated subtype will
18880 correctly decorate the GNAT tree.
18881 (Record_Type_Declaration): Check whether this is a declaration for a
18882 limited derived record before analyzing components.
18883 (Analyze_Component_Declaration): Diagnose record types not explicitly
18884 declared limited when a component has a limited type.
18885 (Build_Derived_Record_Type): Code reorganization to check if some of
18886 the inherited subprograms of a tagged type cover interface primitives.
18887 This check was missing in case of a full-type associated with a private
18889 (Constant_Redeclaration): Check that the subtypes of the partial and the
18890 full view of a constrained deferred constant statically match.
18891 (Mentions_T): A reference to the current type in an anonymous access
18892 component declaration must be an entity name.
18893 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
18894 class_wide type to refer to full type, not to the incomplete one.
18895 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
18896 available. Required to give support to the certified run-time.
18897 (Analyze_Component_Declaration): In case of anonymous access components
18898 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
18899 (Process_Discriminants): For an access discriminant, use the
18900 discriminant specification as the associated_node_for_itype, to
18901 simplify accessibility checks.
18903 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18904 Javier Miranda <miranda@adacore.com>
18906 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
18907 abstract interpretations on an operator, remove interpretations that
18908 yield Address or a type derived from it, if one of the operands is an
18910 (Try_Object_Operation.Try_Primitive_Operation,
18911 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
18912 location when creating the new reference to a primitive or class-wide
18913 operation as a part of rewriting a subprogram call.
18914 (Try_Primitive_Operations): If context requires a function, collect all
18915 interpretations after the first match, because there may be primitive
18916 operations of the same type with the same profile and different return
18917 types. From code reading.
18918 (Try_Primitive_Operation): Use the node kind to choose the proper
18919 operation when a function and a procedure have the same parameter
18921 (Complete_Object_Operation): If formal is an access parameter and prefix
18922 is an object, rewrite as an Access reference, to match signature of
18923 primitive operation.
18924 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
18925 by an expanded name with prefix Standard, when the operands are of an
18926 anonymous access type.
18927 (Remove_Abstract_Operations): If the operation is abstract because it is
18928 inherited by a user-defined type derived from Address, remove it as
18929 well from the set of candidate interpretations of an overloaded node.
18930 (Analyze_Membership_Op): Membership test not applicable to cpp-class
18933 2006-02-13 Bob Duff <duff@adacore.com>
18935 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
18936 redundant use clauses.
18937 In particular, if the scope of two use clauses overlaps, but one is not
18938 entirely included in the other, we should not warn. This can happen
18939 with nested packages.
18940 (Analyze_Subprogram_Renaming): Protect the compiler against previously
18941 reported errors. The bug was reported when the compiler was built
18942 with assertions enabled.
18943 (Find_Type): If the node is a 'Class reference and the prefix is a
18944 synchronized type without a corresponding record, return the type
18947 2006-02-13 Javier Miranda <miranda@adacore.com>
18949 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
18950 if this is the full-declaration associated with a private declaration
18951 that implement interfaces, then the private type declaration must be
18953 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
18954 as aliased. The use of the 'access attribute is not available for such
18955 object (for this purpose the object should be explicitly marked as
18956 aliased, but being an anonymous type this is not possible).
18958 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18959 Robert Dewar <dewar@adacore.com>
18961 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
18962 compilation unit is an elaboration scope.
18963 (Add_Task_Proc): Add '\' in 2-line warning message.
18964 (Activate_All_Desirable): Deal with case of unit with'ed by parent
18966 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18967 Javier Miranda <miranda@adacore.com>
18969 * sem_type.adb (Write_Overloads): Improve display of candidate
18971 (Add_One_Interp): Do not add to the list of interpretations aliased
18972 entities corresponding with an abstract interface type that is an
18973 immediate ancestor of a tagged type; otherwise we have a dummy
18974 conflict between this entity and the aliased entity.
18975 (Disambiguate): The predefined equality on universal_access is not
18976 usable if there is a user-defined equality with the proper signature,
18977 declared in the same declarative part as the designated type.
18978 (Find_Unique_Type): The universal_access equality operator defined under
18979 AI-230 does not cover pool specific access types.
18980 (Covers): If one of the types is a generic actual subtype, check whether
18981 it matches the partial view of the other type.
18983 2006-02-13 Thomas Quinot <quinot@adacore.com>
18985 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
18986 line. This is necessary to allow In_Extended_Main_Unit to provide
18987 correct results for itypes while writing out expanded source.
18988 (Close_File): No need to update the source_index_table here since it's
18989 now done for each line.
18991 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18992 Robert Dewar <dewar@adacore.com>
18994 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
18995 preserve the source unit where the itype is declared, and prevent a
18997 (Note_Implicit_Run_Time_Call): New procedure
18998 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
19001 * sprint.ads: Document use of $ for implicit run time routine call

19005 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
19008 2006-02-13 Bob Duff <duff@adacore.com>
19010 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
19011 Scan_Unsigned, so we do not scan leading blanks and sign twice.
19012 Integer'Value("- 5") and Integer'Value("-+5") now correctly
19013 raise Constraint_Error.
19015 * s-vallli.adb (Scan_Long_Long_Integer): Call
19016 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
19017 do not scan leading blanks and sign twice.
19018 Integer'Value("- 5") and Integer'Value("-+5") now correctly
19019 raise Constraint_Error.
19021 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
19022 Scan_Long_Long_Unsigned): Split out most of the processing from
19023 Scan_Long_Long_Unsigned out into
19024 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
19025 This prevents scanning leading blanks and sign twice.
19026 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
19029 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
19030 out most of the processing from Scan_Unsigned out into
19031 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
19032 This prevents scanning leading blanks and sign twice.
19034 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
19035 use with Modular'Value attribute.
19036 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

19236 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
19237 link to the version that does nothing. This way the task termination

19239 because of an unhandled exception.
19241 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
19242 handler because of an unhandled exception.
19244 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

19250 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
19251 non-tasking version of the soft link for task termination. We do
19252 nothing since if we are using the non-tasking version it
19253 means that the task termination functionality is not used.
19254 (Null_Finalize_Global_List): Add this null version for the procedure
19255 in charge of finalizing the global list for controlled objects.
19256 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
19257 instead for handling run-time termination in a more flexible way.
19258 (Adafinal_NT): This new procedure will take care of finalizing the
19259 global list for controlled objects if needed, but no tasking
19262 * s-tarest.adb (Task_Lock): Do not try to lock again the
19263 Global_Task_Lock if we already own it. Otherwise, we get blocked in
19264 some run-time operations.
19265 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
19266 until all nested locks have been released.
19267 (Task_Wrapper): Call the fall-back task termination handler. It
19268 applies to all tasks but the environment task.
19269 (Finalize_Global_Tasks): Add the call for the task termination
19270 procedure for the environment task.
19271 (Task_Wrapper): suppress warnings around declaration of
19272 Secondary_Stack_Address.
19274 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
19275 moved to the Common_ATCB record.
19276 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
19277 Common_ATCB record.
19278 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
19279 Common_ATCB record.
19281 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
19282 Fall_Back_Handler, and Specific_Handler.
19284 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
19285 defined in Ada.Task_Termination, to avoid circular dependencies.
19286 (Termination_Handler): Redefine this type here, alredy defined in
19287 Ada.Task_Termination, for avoiding circular dependencies.
19288 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
19289 for storing task termination handlers. In addition,
19290 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
19291 Common_ATCB because it is used by both the regular and the restricted
19293 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
19294 Common_ATCB because it is used by both the regular and the restricted
19296 (Common_ATCB): Added a dynamic task analyzer field.
19298 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
19299 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
19300 (Task_Wrapper): Call the task termination handler. It applies to all
19301 tasks but the environment task.
19302 (Finalize_Global_Tasks): Call the task termination procedure for the
19303 environment task. The call to Finalize_Global_List is now performed
19304 using the soft links mechanism.
19305 (Task_Wrapper): added dynamic stack analysis.
19307 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
19308 potentially blocking operations has been moved from
19309 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
19310 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
19311 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
19312 this run-time check.
19314 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
19315 of task termination procedure.
19316 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

19358 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
19359 to the specification because the frontend generates code that uses this
19361 (Set_Interface_Table): Add missing assertion.
19362 Update documentation describing the run-time structure.
19363 (Displace): New subprogram that displaces the pointer to the object
19364 to reference one of its secondary dispatch tables.
19365 (IW_Membership): Modified to use the new table of interfaces.
19366 (Inherit_TSD): Modified to use the new table of interfaces.
19367 (Register_Interface_Tag): Use the additional formal to fill the
19368 contents of the new table of interfaces.
19369 (Set_Interface_Table): New subprogram that stores in the TSD the

19384 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
19385 in all the calls to Expand_Interface_Thunk. Instead of referencing the
19386 record component containing the tag of the secondary dispatch table we
19387 have to use the Offset_To_Top run-time function to get this information;
19388 otherwise if the pointer to the base of the object has been displace
19389 we get a wrong value if we use the 'position attribute.
19391 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
19392 all the calls to Expand_Interface_Thunk.
19393 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
19394 interfaces; hence the call to Set_Interface_Table was clearly wrong.

19396 ensure that the interfaces implemented by the ancestors are placed
19397 at the header of the generated list.
19398 (Expand_Interface_Conversion): Handle the case in which the displacement
19399 associated with the interface conversion is not statically known. In
19400 this case we generate a call to the new run-time subprogram Displace.

19402 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
19403 Get_Tagged_Kind and Set_Tagged_Kind.
19404 (Tagged_Kind): New function that determines the tagged kind of a type
19405 with respect to limitedness and concurrency and returns a reference to

19408 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
19409 primary dispatch table for a type.

19411 secondary dispatch table respectively of a tagged type.
19413 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.

19425 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
19426 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
19427 RE_TK_Tagged, RE_TK_Task.
19429 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
19430 Init_Secondary_Tags_Internal to allow its use with interface types and
19431 also to generate the code for the new additional actual required
19432 by Set_Offset_To_Top.
19433 (Build_Init_Statements): In case of components associated with abstract
19434 interface types there is no need to generate a call to its IP.
19435 (Freeze_Record_Type): Generate Select Specific Data tables only for
19437 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
19438 the bodies and specifications of the predefined primitive operations
19439 dealing with dispatching selects and abort, 'Callable, 'Terminated only
19440 for concurrent types.
19442 * exp_sel.ads, exp_sel.adb: New files.
19444 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
19445 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
19446 properly protected objects and attach handler in the case of the
19447 restricted profile.
19448 Move embeded package Select_Expansion_Utilities into a separate external

19451 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
19452 (Build_K, Build_S_Assignment): New subprograms, part of the select
19453 expansion utilities.

19456 where the trigger is a dispatching procedure of a limited tagged type.
19458 2005-12-09 Olivier Hainque <hainque@adacore.com>
19460 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
19461 pointer initialization values. Make a SAVE_EXPR instead. Add comments
19462 about the use and expansion of SAVE_EXPRs in the various possible
19463 renaming handling cases.
19464 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
19465 abusing DECL_FCONTEXT.

19565 covered by the tag of the source.
19567 2005-12-09 Robert Dewar <dewar@adacore.com>
19569 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

19584 component associated with the secondary table of an abstract interface
19585 type, return the entity associated with such abstract interface type.
19586 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
19587 base type to create anonymous subtype, because entity may be a locally
19588 declared subtype or generic actual.
19589 (Find_Interface): New subprogram that given a tagged type and one of its
19590 component associated with the secondary table of an abstract interface
19591 type, return the entity associated with such abstract interface type.
19593 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
19594 conversion cannot be handled at compile time. In this case we pass this
19595 information to the expander to generate the appropriate code.

19630 copied component does not have a known static Esize, then reset
19631 the size and positional fields of the new component.
19632 (Analyze_Component_Declaration): A limited component is
19633 legal within a protected type that implements an interface.
19634 (Collect_Interfaces): Do not add to the list the interfaces that
19635 are implemented by the ancestors.
19636 (Derived_Type_Declaration): If the parent of the full-view is an
19637 interface perform a transformation of the tree to ensure that it has
19638 the same parent than the partial-view. This simplifies the job of the
19639 expander in order to generate the correct object layout, and it is
19640 needed because the list of interfaces of the full-view can be given in
19642 (Process_Full_View): The parent of the full-view does not need to be
19643 a descendant of the parent of the partial view if both parents are
19645 (Analyze_Private_Extension_Declaration): If declaration has an explicit
19646 "limited" the parent must be a limited type.
19647 (Build_Derived_Record_Type): A derived type that is explicitly limited

19660 (Process_Full_View): Improve the check for the "no hidden interface"
19661 rule as defined by AI-396.
19663 2005-12-09 Robert Dewar <dewar@adacore.com>
19665 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
19666 types, not on record subtypes.
19667 (Freeze_Entity): Code cleanup. Add barrier to the loop
19668 that generates the references for primitive operations. This allows to
19669 remove an unnecessary exception handler.

19720 available user-specified stream attributes on limited parameters to
19721 also test the type directly rather than only its underlying type (for
19722 Ada 95) and, in the case of Ada 2005, to check that the user-specified
19723 attributes are visible at the point of the subprogram declaration.
19724 For Ada 2005, the error message is modified to indicate that the
19725 type's stream attributes must be visible (again, only for -gnat05).

19757 types use the corresponding record type. This was not needed before
19758 the implementation of Ada 2005 synchronized types because
19759 concurrent types were never tagged types in Ada 95.

19887 * socket.c: Add extern int h_errno for rtems since networking header
19888 files are not available at this point in a tool bootstrap. Newlib

19892 Roger Sayle <roger@eyesopen.com>
19895 * misc.c (internal_error_function): Don't use vsprintf to format
19896 the error message text, instead use pp_format_text and the new

19907 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
19908 a temporary if taking the address of something that is neither
19909 reference, declaration, or constant, since the gimplifier
19910 can't handle that case.
19912 2005-11-17 Laurent Guerby <laurent@guerby.net>
19915 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

19982 * gen-soccon.c: Complete value expansion should not be performed on
19983 TARGET, as it has the form of a math expression, and some components
19984 may be platform-defined macros.
19985 For VxWorks, generate the OK and ERROR values.
19986 New constants giving the sizes of the components of C struct timeval.

19992 * types.ads: Include All_Checks in Suppress_Array
19994 * checks.adb (Check_Needed): Remove kludge for a/=b rewritten as
19995 not(a=b), since we no longer do this rewriting, and hence it is not
19997 (Elaboration_Checks_Suppressed): Add special casing to
19998 deal with different cases of static and dynamic elaboration checks (all
19999 checks does not count in the first case, but does in the second).
20000 (Expr_Known_Valid): Do not assume that the result of any arbitrary
20001 function call is valid, since this is not the case.
20002 (Ensure_Valid): Do not apply validity check to a real literal
20003 in a universal or fixed context
20005 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
20006 elementary types using the operator in standard. It is cleaner not to
20007 modify the programmers intent, especially in the case of floating-point.
20008 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
20009 it did not matter because we always rewrote a/=b to not(a=b).
20010 (Expand_Allocator_Expression): For an allocator expression whose nominal
20011 subtype is an unconstrained packed type, convert the expression to its
20012 actual constrained subtype.
20013 Implement warning for <= or >= where < or > not possible
20014 Fix to Vax_Float tests (too early in many routines, causing premature
20015 Vax_Float expansions.

20021 of pragma Suppress (All_Checks)
20022 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
20023 a string literal for precise control over warnings.
20024 Avoid raise of pragma in case of unrecognized pragma and just return
20027 * sem_prag.ads: Minor reformatting
20029 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
20030 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter
20031 Switch. Do not handle any exception.
20032 Include -gnatwx as part of -gnatg (warn on redundant parens)
20033 Allow optional = after -gnatm
20034 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
20035 longer sets Elaboration_Checks.
20036 Code to set warning mode moved to Sem_Warn
20037 so that it can be shared by pragma processing.
20039 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
20042 * s-taprop-solaris.adb:
20043 Change some <= to =, to avoid new warning

20049 2005-11-14 Robert Dewar <dewar@adacore.com>
20051 * exp_vfpt.adb: Handle /= case
20052 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

20060 Increase default priority on Lynx from 15 to 17, and meet the Ada
20061 requirement that Default_Priority be ((Priority'First +
20062 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

20164 we are not defining the type.
20165 <E_Record_Type>: Likewise.
20166 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
20167 to get advantage of the new maybe_stabilize_reference interface, to
20168 ensure that what we reference is indeed stabilized instead of relying
20169 on assumptions on what the stabilizer does.
20170 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
20171 type imported through a limited_with clause, use its non-limited view.
20172 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
20174 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
20175 of #if sections + explicit comparisons of convention identifiers.

20177 before early-returning for certain types when code generation is

20181 that we are not defining.
20182 (elaborate_expression_1): Do not create constants when creating
20183 variables needed by the debug info: the dwarf2 writer considers that
20184 CONST_DECLs is used only to represent enumeration constants, and emits
20186 (gnat_to_gnu_entity) <object>: When turning a non-definition of an

20202 is provided by the front-end, use that subtype to compute the size of
20203 the deallocated object.

20205 check for a potential violation of a No_Elaboration_Code restriction.

20211 without need to check for the success indication.

20213 pass false instead of 0 as the FORCE argument which is a bool.
20214 (Identifier_to_gnu): Remove checks ensuring that an renamed object
20215 attached to a renaming pointer has been properly stabilized, as no such
20216 object is attached otherwise.

20218 function uses the "target pointer" return mechanism.
20219 Reinstate conversion of the actual to the type of the formal
20220 parameter before any other specific treatment based on the passing

20230 * utils2.c (gnat_build_constructor): Only sort the fields for possible
20231 static output of record constructor if all the components are constant.
20232 (gnat_build_constructor): For a record type, sort the list of field
20233 initializers in increasing bit position order.
20234 Factor common code to build a storage type for an unconstrained object
20235 from a fat or thin pointer type and a constrained object type.
20236 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
20237 types variants, and process special cases of VIEW_CONVERT expressions
20238 as their NOP_EXPR counterpart to ensure we get to the
20239 CORRESPONDING_VARs associated with CONST_DECls.
20240 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
20241 on the right-hand side.

20248 extracting the object if converting to a type variant.
20249 (create_var_decl): When a variable has an initializer requiring code
20250 generation and we are at the top level, check for a potential violation
20251 of a No_Elaboration_Code restriction.
20252 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
20253 SIZE and SIZE_UNIT which we need for later back-annotations.

20436 access to unconstrained packed array type, annotate the dereference
20437 with an actual subtype so GIGI can make a correct size computation.
20438 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
20439 'Unrestricted_Access, if the designated type is an interface we
20440 add a type conversion to force the displacement of the pointer
20441 to the secondary dispatch table.
20442 Use Universal_Real instead of Long_Long_Float when we need a high
20443 precision float type for the generated code (prevents gratuitous
20444 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
20445 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
20446 'Terminated for task interface class-wide objects. Generate a call to
20447 the predefined dispatching routine used to retrieve the _task_id from
20448 a task corresponding record.

20474 for any entity whose value is known from the condition of the first
20476 (Expand_N_Return_Statement): When returning a mutable record, convert
20477 the return value into its actual subtype in order to help the backend
20478 to return the actual size instead of the maximum. This is another

20498 a process handle, not need to convert.
20499 (__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.

20810 leave it more clear.
20811 (Analyze_Type_Declaration): If type has previous incomplete tagged

20868 whose default is abstract because the object type itself is abstract.
20869 (Find_Type): If the type is incomplete and appears as the prefix of a
20870 'Class reference, it is tagged, and its list of primitive operations
20871 must be initialized properly.

21733 g-soccon-solaris.ads, g-soccon-mingw.ads, g-soccon-vxworks.ads,
21734 g-soccon-freebsd.ads: Add new constants:
21736 SO_RCVTIMEO/SO_SNDTIMEO
21740 Move all target-specific file inclusions and macro definitions to
21741 gsocket.h, in order to ensure that any C code in socket.c will see a
21742 set of constants that is consistent with the contents of g-soccon.ads.
21744 * gsocket.h: Code imported from gen-soccon.c:
21745 Move all target-specific file inclusions and macro definitions to
21746 gsocket.h, in order to ensure that any C code in socket.c will see a set
21747 of constants that is consistent with the contents of g-soccon.ads.
21748 This change also makes gen-soccon self-contained (removing dependencies
21749 upon GCC internal headers).
21751 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
21753 (To_Inet_Addr): Now a procedure instead of a function, more efficient.

21887 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
21888 from object notation, the original node is unanalyzed and carries no
21889 semantic information, so that accessiblity checks must be performed on
21890 the type of the actual itself.

21946 position set is provided, we compute one in order to reduce the maximum
21947 length of the keys. This computation first selects a character
21948 position between 1 and the minimum length of the keys in order to
21949 avoid reducing one of the keys to an empty string.
21950 (Initialize, Compute): When the ratio V to K is too low, the algorithm
21951 does not converge. The initialization procedure now comes with a
21952 maximum number of iterations such that when exceeded, an exception is
21953 raised in Compute. The user can initialize this ratio to another value

21963 to keep the association between the two entities.
21964 Update copyright notice

22110 Ed Schonberg <schonberg@adacore.com>
22112 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
22113 become local to the whole package.
22114 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
22115 the package was already analyzed the new algorithm "replaces" the
22116 real entities by the shadow ones. This is required to ensure that
22117 the order of these entities in the homonym chains does not change;
22118 otherwise we can have undefined references at linking time because
22119 in case of conflicts the external name of the entities will have
22120 a suffix that depends on the order of the entities in the chain.
22121 (Remove_Limited_With_Clause): Complementary code that completes the
22122 new algorithm and replaces the shadow entities by the real ones.
22123 (Install_Limited_Withed_Unit): When unchaining entities before the
22124 installation of the shadow entities, only regular entities of the
22125 public part must be taken into account. This is required to
22126 keep this routine in synch with the work done by Remove_Limited_
22128 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
22129 even if unit is analyzed, because the analysis of the unit is
22130 idempotent in any case, and the limited view of the unit may have to
22131 be installed for proper visibility.
22132 (Expand_Limited_With_Clause): Even if the unit in the implicit
22133 with_clause has been analyzed already, a limited view of the package
22134 must be built for the current context, if it does not exist yet.

22137 Javier Miranda <miranda@adacore.com>
22138 Gary Dismukes <dismukes@adacore.com>
22140 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
22141 defining entity for the instance body, make a new defining identifier
22142 rather than copying the entity of the spec, to prevent accidental
22143 sharing of the entity list.
22144 (Check_Private_View): When exchanging views of private types, build the
22145 list of exchanged views as a stack, to ensure that on exit the exchanges
22146 are undone in the proper order.
22147 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
22148 Restore the compilation environment in case of instantiation_error.
22149 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
22150 for an anonymous access result.
22151 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
22152 (Formal_Entity): Handle properly the case of a formal package that
22153 denotes a generic package renaming.
22155 2005-09-01 Thomas Quinot <quinot@adacore.com>
22157 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
22158 clause if the array aggregate is surrounded by parentheses.
22160 2005-09-01 Cyrille Comar <comar@adacore.com>
22161 Gary Dismukes <dismukes@adacore.com>
22162 Ed Schonberg <schonberg@adacore.com>
22163 Javier Miranda <miranda@adacore.com>
22165 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
22167 to check if a type is Constrained in cases related to code generation
22168 (rather than semantic checking) since otherwise we do not generate
22169 similar code for mutable private types depending if their
22170 discriminants are visible or not.
22171 (Check_Abstract_Overriding): Do not complain about failure to override
22172 the primitive operations used in dispatching selects since they will
22173 always be overriden at the freeze point of the type.
22174 (Access_Definition): Separate out handling for resetting the scope
22175 of an anonymous access function result type. Retrieve the scope
22176 of the associated function rather than using Current_Scope, which
22177 does not have a consistent value (depends on whether we're in the
22178 middle of analyzing formal parameters). Add ??? comment about
22179 finding a cleaner way to handle the special cases of scope setting.
22180 (Process_Incomplete_Dependents): A protected operation is never a
22181 dispatching operation (only its wrapper may be).
22182 (Build_Derived_Record_Type): In case of tagged private types that
22183 implement interfaces add derivation of predefined primitive
22185 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
22186 by two parameters that are used in case of derivation from abstract
22187 interface types: No_Predefined_Prims is used to avoid the derivation
22188 of predefined primitives from the interface, and Predefined
22189 Prims_Only is used to complete the derivation predefined primitives
22190 in case of private tagged types implementing interfaces.
22191 Fix typo in comments
22192 (Find_Interface_In_Descendant): Protect the frontend against
22193 wrong code with large circularity chains.
22194 (Is_Private_Overriding): Add support for entities overriding interface
22195 subprograms. The test failed because Entities associated with overriden
22196 interface subprograms are always marked as hidden (and used to build
22197 the secondary dispatch table); in this case the overriden entity is
22198 available through the field abstract_interface_alias (cf. override_
22199 dispatching_operation)
22200 (Access_Definition): Set the scope of the type to Current_Scope for the
22201 case of a function with an anonymous access result type.
22202 (Access_Subprogram_Declaration): Handle creation of the type entity for
22203 an access-to-function type with an anonymous access result.
22204 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
22205 in handling for N_Access_Function_Definition.
22206 (Analyze_Subtype_Declaration): Modify the text of error message.
22207 (Derived_Type_Declaration): Modify the text of error message.
22208 (Process_Subtype): Modify the text of error message plus cleanup
22209 of one redundant error message.
22210 (Analyze_Component_Declaration): Code cleanup.
22211 (Analyze_Object_Declaration): Code cleanup.
22212 (Analyze_Subtype_Declaration): Propagate the null-exclusion
22213 attribute in case of access types. Code cleanup.
22214 (Array_Type_Declaration): Code cleanup.
22215 (Process_Discriminants): Create the new null-excluding itype
22216 if required. Code cleanup.
22217 (Process_Subtype): Create the new null-excluding itype if
22218 required. Code cleanup.
22219 (Build_Derived_Record_Type): Code cleanup to avoid calling
22220 twice the subprogram derive_subprograms in case of private
22221 types that implement interfaces. In this particular case the
22222 subprogram Complete_Subprograms_Derivation already does the
22223 job associated with the second call.
22225 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
22226 conversion to the full view when generating an operation for a
22227 discriminant whose type may currently be private.
22229 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22230 Javier Miranda <miranda@adacore.com>
22232 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
22233 V (Obj.F), the rewriting does not involve the indexed component, but
22234 only the selected component itself.
22235 Do not apply the transformation if the analyzed node is an actual of a
22236 call to another subprogram.
22237 (Complete_Object_Operation): Retain the entity of the
22238 dispatching operation in the selector of the rewritten node. The
22239 entity will be used in the expansion of dispatching selects.
22240 (Analyze_One_Call): Improve location of the error message associated
22242 (Analyze_Selected_Component): No need to resolve prefix when it is a
22243 function call, resolution is done when parent node is resolved, as
22245 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
22246 when attempting to resolve a call transformed from its object notation.
22247 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
22248 of the argument list for each interpretation of the operation.
22249 (Try_Object_Operation): The designated type of an access parameter may
22250 be an incomplete type obtained through a limited_with clause, in which
22251 case the primitive operations of the type are retrieved from its full
22253 (Analyze_Call): If this is an indirect call, and the return type of the
22254 access_to_subprogram is incomplete, use its full view if available.
22256 2005-09-01 Javier Miranda <miranda@adacore.com>
22257 Gary Dismukes <dismukes@adacore.com>
22259 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
22260 access types the null-exclusion and access-to-constant attributes must
22262 (Analyze_Return_Statement): When the result type is an anonymous access
22263 type, apply a conversion of the return expression to the access type
22264 to ensure that appropriate accessibility checks are performed.
22265 (Analyze_Return_Type): For the case of an anonymous access result type,
22266 generate the Itype and set Is_Local_Anonymous_Access on the type.
22267 Add ??? placeholder for check to disallow returning a limited object
22268 in Ada 2005 unless it's an aggregate or a result of a function call.
22269 Change calls from Subtype_Mark to Result_Definition.
22270 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
22271 Result_Definition in call to Make_Function_Specification.
22272 (Build_Body_To_Inline): Change Set_Subtype_Mark to
22273 Set_Result_Definition.
22274 (Make_Inequality_Operator): Change formal Subtype_Mark to
22275 Result_Definition in call to Make_Function_Specification.
22276 (Process_Formals): Create the new null-excluding itype if required.
22277 (New_Overloaded_Entity): For an entity overriding an interface primitive
22278 check if the entity also covers other abstract subprograms in the same
22279 scope. This is required to handle the general case, that is, overriding
22280 other interface primitives and overriding abstract subprograms inherited
22281 from some abstract ancestor type.
22282 (New_Overloaded_Entity): For an overriding entity that comes from
22283 source, note the operation that it overrides.
22284 (Check_Conformance, Type_Conformant): Addition of one new formal
22285 to skip controlling formals in the analysis. This is used to
22286 handle overloading of abstract interfaces.
22287 (Base_Types_Match): Add missing case for types imported from
22288 limited-with clauses
22289 (New_Overloaded_Entity): Add barrier to protect the use of
22290 the "alias" attribute.
22292 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22294 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
22295 verify that the procedure and the entry are mode conformant.
22296 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
22297 as a different operator, which is often a cut-and-paste error.
22299 2005-09-01 Javier Miranda <miranda@adacore.com>
22300 Ed Schonberg <schonberg@adacore.com>
22302 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
22303 used in controlling parameters exclude null because it is necessary to
22304 read the tag to dispatch, and null has no tag.
22305 (Override_Dispatching_Operation): If the previous operation is inherited
22306 from an interface, it becomes hidden and does not participate in later
22309 2005-09-01 Javier Miranda <miranda@adacore.com>
22310 Ed Schonberg <schonberg@adacore.com>
22311 Gary Dismukes <dismukes@adacore.com>
22313 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
22314 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
22315 the expander will generate the corresponding run-time check to evaluate
22317 (Resolve_Call): Check for legal type of procedure name or prefix that
22318 appears as a trigger in a triggering alternative.
22319 (Valid_Conversion): If expression is ambiguous and the context involves
22320 an extension of System, remove System.Address interpretations.
22321 (Resolve_Qualified_Expression): Reject the case of a specific-type
22322 qualification applied to a class-wide argument. Enhance comment
22323 to explain checking of Original_Node.
22324 (Resolve_Type_Conversion): The location of the error message was not
22325 general enough to handle the general case and hence it has been removed.
22326 In addition, this patch improves the text of the message.
22327 (Resolve_Type_Conversion): Add missing support for access to interface
22329 (Resolve_Type_Conversion): If the target is a class-wide interface type,
22330 do not expand if the expression is the actual in a call, because proper
22331 expansion will take place when the call itself is expanded.
22332 (Resolve_Allocator): If the context is an unchecked conversion, the
22333 allocator inherits its storage pool, if any, from the target type of
22336 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22337 Javier Miranda <miranda@adacore.com>
22339 * sem_type.adb (Add_One_Interp): If a candidate operation is an
22340 inherited interface operation that has an implementation, use the
22341 implementation to avoid spurious ambiguities.
22342 (Interface_Present_In_Ancestor): In case of concurrent types we can't
22343 use the Corresponding_Record_Typ attribute to look for the interface
22344 because it is set by the expander (and hence it is not always
22345 available). For this reason we traverse the list of interfaces
22346 (available in the parent of the concurrent type).
22347 (Interface_Present_In_Ancestor): Handle entities from the limited view
22349 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22351 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
22352 from the list of required components.
22353 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
22354 primitive procedure of a limited interface with a controlling first
22356 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
22358 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
22359 capture if it is generated in the second operand of a short-circuit
22361 Do not capture values for variables with address clauses.
22362 (Is_Object_Reference): Treat a function call as an object reference only
22363 if its type is not Standard_Void_Type.
22365 2005-09-01 Ed Schonberg <schonberg@adacore.com>
22367 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
22368 to a variable that is statically known to be constant.
22370 2005-09-01 Geert Bosch <bosch@adacore.com>
22371 Robert Dewar <dewar@adacore.com>
22373 * ttypef.ads (VAXDF_Safe_First): Use correct value for constant.

22380 Document that bounds of result of Base_Name match the input index
22382 Add documentation on environment variable syntax for Expand_Path
22384 * gnat_ugn.texi: Update documentation to include mention of -m switches
22385 Document new treatment of wide characters in max line length
22387 Remove -gnatL/-gnatZ switches, no longer used.
22388 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
22391 * gnat_rm.texi: Add doc for two argument form of pragma
22392 Float_Representation.
22393 Add documentation for pragma No_Strict_Aliasing
22394 Add note that explicit component clause overrides pragma Pack.
22395 Add documentation of pragma Debug_Policy

22408 Note that the platform-specific version of g-soccon.ads for VMS is now
22409 named g-soccon-vms.ads (it was previously g-soccon-vms.adb, although it

23150 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
23151 longer protected objects. They have been replaced by lower-level
23152 suspension objects made up by a mutex and a condition variable (or
23153 their equivalent given a particular OS) plus some internal data to
23154 reflect the state of the suspension object.
23155 (Initialize, Finalize): Add this initialization procedure for
23156 Suspension_Object, which is a controlled type.
23157 (Finalize): Add the finalization procedure for Suspension_Object,
23158 which is a controlled type.
23160 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
23161 Ada.Synchronous_Task_Control because there is no longer a need for a
23162 VxWorks specific version of this package. Target dependencies
23163 has been moved to System.Task_Primitives.Operations.
23165 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
23167 (InitializeCriticalSection, EnterCriticalSection,
23168 LeaveCriticalSection, DeleteCriticalSection): Replace the type
23169 pCriticalSection by an anonymous access type so that we avoid problems
23170 of accessibility to local objects.

23176 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
23177 set the environment task mask here.
23178 (Current_State): Add this function that returns the state of the
23180 (Set_False): Add this procedure that sets the state of the suspension
23182 (Set_True): Add this procedure that sets the state of the suspension
23183 object to True, releasing the task that was suspended, if any.
23184 (Suspend_Until_True): Add this procedure that blocks the calling task
23185 until the state of the object is True. Program_Error is raised if
23186 another task is already waiting on that suspension object.
23187 (Initialize): Add this procedure for initializing the suspension
23188 object. It initializes the mutex and the condition variable which are
23189 used for synchronization and queuing, and it sets the internal state
23191 (Finalize): Add this procedure for finalizing the suspension object,
23192 destroying the mutex and the condition variable.

23197 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
23198 which provides a low-level abstraction (using operating system
23199 primitives) for Ada.Synchronous_Task_Control.
23200 This object is made up by a mutex (for ensuring mutual exclusion), a
23201 condition variable (for queuing threads until the condition is
23202 signaled), a Boolean (State) indicating whether the object is open,
23203 and a Boolean (Waiting) reflecting whether there is a task already
23204 suspended on this object.

23221 System.Parameters.No_Abort is True.
23223 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
23224 is no longer done in the body of s-taprop

23397 * exp_ch5.adb (Expand_N_Return_Statement): When a function's result
23398 type is a class-wide type, emit a run-time check that the accessibility

23469 type derivation of private tagged types implementing interfaces.
23470 In this case some interface primitives may have been overriden

23560 * i-cpp.ads, i-cpp.adb:
23561 This package has been left available for compatibility with previous
23562 versions of the frontend. As part of the new layout this is now a

23616 access to subprograms must be recursive.
23617 (Is_Unchecked_Conversion): Improve the test that recognizes
23618 instantiations of Unchecked_Conversion, and allows them in bodies that
23619 are to be inlined by the front-end. When the body comes from an
23620 instantiation, a reference to Unchecked_Conversion will be an
23621 Expanded_Name, even though the body has not been analyzed yet.

23642 object or component (that is, when Is_Local_Anonymous_Access is true).
23643 Prevent the special checks for conversions of access discriminants in
23644 the case where the discriminant belongs to a nonlimited type, since
23645 such discriminants have their accessibility level defined in the same
23646 way as a normal component of an anonymous access type.
23647 (Resolve_Allocator): When an allocator's designated type is a class-wide
23648 type, check that the accessibility level of type given in the
23649 allocator's expression or subtype indication is not statically deeper

23666 pragma Restrictions (No_Obsolescent_Features).
23667 (Check_Direct_Boolean_Operator): If the boolean operation has been
23668 constant-folded, there is nothing to check.
23669 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
23670 check on possible violation of restriction No_Direct_Boolean_Operators
23671 until after expansion of operands, to prevent spurious errors when

23974 the "simple_choice" member in a variant record, in accordance with the
23975 description in the package spec: the information output for a constant
23976 should be "S number", not "SS number".
23977 (Get_Encoded_Name): Return at once if not generating code. Avoids name

24677 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

24684 is disabled, the entity denoted by the argument is the access type

24696 denotes a type in the class.
24697 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
24698 of Name_Generic_Dispatching_Constructor.
24700 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

25443 uses of the Access_Disp_Table attribute to reference the first dispatch
25444 table associated with a tagged type. As
25445 part of the implementation of abstract interface types,

25447 tables (rather than a single dispatch table).
25448 Similarly, upgrade all the references to Tag_Component by the
25449 new attribute First_Tag_Component.
25450 (Find_Inherited_TSS): Moved to exp_tss.

25464 determine the amount of data to be copied.
25466 * par.adb (P_Interface_Type_Definition): New subprogram that parses the

25494 (Task_Body_Procedure): Removed.
25495 (Set_Task_Body_Procedure): Removed.
25496 These subprogram have been removed because the attribute
25497 Task_Body_Procedure has been moved to the corresponding task type
25498 or task subtype entity to leave a field free to store the list
25499 of interfaces implemented by a task (for AI-345)

25564 expression to the type of the object when the object is constant.
25565 Reverse defer_debug_incomplete_list before traversing it, so that trees
25566 are processed in the order at which they were added to the list. This
25567 order is important when using the stabs debug format.
25568 If we are deferring the output of debug information, also defer this
25569 output for a function return type.
25570 When adding fields to a record, prevent emitting debug information

25611 N_Qualified_Expression.
25613 * sem_ch3.adb (Derived_Type_Declaration): New predicate
25614 Comes_From_Generic, to recognize accurately that the parent type in a
25615 derived type declaration can be traced back to a formal type, because
25616 it is one or is derived from one, or because its completion is derived
25618 (Constrain_Component_Type): If component comes from source and has no
25619 explicit constraint, no need to constrain in in a subtype of the
25621 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.

25652 that come from packed arrays).
25653 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the

25662 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
25663 over both visible and private declarations to remove them from tree,

25680 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
25681 that appears in the instantiation rather than the internal subtype
25682 generated in the wrapper package, to avoid anomalies in gigi when the
25683 target is derived from a private type whose full view is an access type.
25685 2005-03-15 Robert Dewar <dewar@adacore.com>
25687 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
25689 Add documentation to replace the use of this flag
25690 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
25693 2005-03-15 Thomas Quinot <quinot@adacore.com>
25695 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
25696 here from exp_attr so it can be shared between exp_attr and exp_dist.
25697 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
25698 all TSS names, not a subset thereof, and the previous name introduced
25699 an unnecessarily confusion that a distinction might exist between
25700 "OK" TSS names and some "not OK" TSS names.
25702 2005-03-15 Doug Rupp <rupp@adacore.com>
25704 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
25707 2005-03-15 Pascal Obry <obry@adacore.com>
25708 Eric Botcazou <ebotcazou@adacore.com>
25712 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
25713 when IN_RTS. This is to work around a bootstrap path problem.
25715 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
25716 table and pass it to __gnat_install_SEH_handler().
25717 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
25719 * lang.opt: Fix specification of -fRTS=.
25721 2005-03-15 Doug Rupp <rupp@adacore.com>
25722 Bernard Banner <banner@adacore.com>
25723 Vincent Celier <celier@adacore.com>
25724 Arnaud Charlet <charlet@adacore.com>
25727 This change works fine when gnatlib is built from the gcc directory,
25728 but does not work when using the libada Makefile, since GCC_FOR_TARGET
25729 is not passed to ada/Makefile.in, so more work is needed by a
25730 Makefile/configure expert.
25732 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
25733 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
25734 Setup gnatlink switch -M for x86_64 linux, as it is already setup
25736 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
25737 Run ranlib on libgccprefix.a
25738 Define PREFIX_OBJS for Darwin, to build libgccprefix.
25739 (ADA_INCLUDE_SRCS): Split Ada packages.
25741 2005-03-15 Robert Dewar <dewar@adacore.com>
25743 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
25745 * impunit.adb: Add GNAT.UTF_32
25747 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
25749 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
25750 now uses GNAT.UTF_32).
25752 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
25753 capabilities for categorizing characters using Unicode categories
25755 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25757 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
25758 instantiation that has been rewritten as a package body, retrieve spec
25759 to generate proper name for implicit_with_clause.
25760 (Install_Parents): Recognize a parent that is an instantiation but has
25761 been rewritten as a package declaration during analysis.
25763 2005-03-15 Javier Miranda <miranda@adacore.com>
25764 Ed Schonberg <schonberg@adacore.com>
25766 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
25767 parameter reported some error we immediately return. This improves the
25768 behaviour of the frontend in case of errors.
25769 (Install_Parent, Remove_Parent): Introduce new flag
25770 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
25771 ancestor of a generic child unit, when the child is being instantiated.
25772 (Inline_Instance_Body): If we are compiling the private
25773 part or the body of a child unit, restore the proper visibility of the
25774 parents after compiling the instance body.
25776 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25777 Javier Miranda <miranda@adacore.com>
25780 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
25781 of a private type, in which case it is underlying_type that denotes
25782 the proper task. Also modified to use the new entity attribute
25783 that is directly available in the task type and task subtype entities
25784 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
25785 arrays when other dimensions than the first are constrained by
25786 discriminants of an enclosing record.
25787 (Insert_Explicit_Dereference): If the prefix is an indexed component or
25788 a combination of indexed and selected components, find ultimate entity
25789 and generate the appropriate reference for it, to suppress spurious
25791 (Note_Possible_Modification): If an entity name has no entity, return.
25792 (Is_Variable): A function call never denotes a variable.
25793 (Requires_Transient_Scope): For record types, recurse only on
25794 components, not on internal subtypes that may have been generated for
25795 constrained components.
25797 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25799 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
25800 Eliminated as candidates for resolution. Both efficient, and avoids
25801 anomalies with operators declared in deleted code.
25802 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
25803 expansion is disabled (as when compiling a generic) to prevent spurious
25804 warnings on prefixes of selected components.
25806 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25808 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
25809 attached to a list before checking whether it appears in the private
25810 declarations of the current package.
25811 (Make_Inequality_Operator): Insert declaration in proper declarative
25812 list rather than just setting the Parent field, so that
25813 Is_Private_Declaration can handle it properly.
25815 2005-03-15 Ed Schonberg <schonberg@adacore.com>
25817 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
25818 a renaming a body, check that the renamed subprogram in not intrinsic.
25819 (Find_Direct_Name): If several use_visible entities hide
25820 each other, and the context is a predefined file compiled through
25821 rtsfind, keep only the entity that comes from a predefined file.
25823 2005-03-15 Geert Bosch <bosch@adacore.com>
25825 * s-fatgen.adb (Valid): Extend special exceptions to account for long
25826 long float padding to also cover AMD64 and IA64.
25828 2005-03-15 Gary Dismukes <dismukes@adacore.com>
25830 * s-imgwch.adb: Add with and use of Interfaces.

26149 "dispatching" rather than "primitive" operations, since dispatching
26150 calls are now allowed to abstract formal subprograms (which are not
26152 Char_Literal_Value field is now a Uint
26153 (Resolve_Slice): If the prefix is an access to an unconstrained array,
26154 compute the actual subtype of the designated object to impose the proper
26156 (Resolve_Selected_Component): Do not insert an access check if the
26157 prefix is an access type: such a node is expanded into an explicit
26158 dereference, on which the access check is performed anyway. Removes
26159 expensive duplicate checks.
26160 (Resolve_Call): Use new flag Is_Obsolescent and field

26163 Add support for wide wide character type
26164 (Resolve_Allocator): Replace the error message on wrong null-exclusion
26165 value by a warning message.
26166 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
26167 as fixed-point, and one of the operands is non-static and universal, it
26168 can only be an illegal exponentiation operation, in which case there is
26169 no real value to retrieve.
26171 * exp_strm.adb: Add support for wide wide character type
26172 (Build_Elementary_Input_Call): Compute the size of the stream element by

26220 * stringt.ads, stringt.adb: Handle full UTF-32 range.
26221 Remove ["0A"] from comment, since it can look like a line terminator.
26222 Currently we don't permit this, but this is under discussion by the
26223 ARG, and it is easy enough to use a different example.
26225 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
26226 handling UTF-32 encoding for wide wide character.

26285 describing the new layout.
26286 (Dispatch_Table): The expander computes the actual array size, allocates
26287 the Dispatch_Table record accordingly, and generates code that displaces
26288 the base of the record after the Typeinfo_Ptr component. The access to
26289 these components is done by means of local functions.
26290 (Offset_To_Top): New function.
26291 (Typeinfo_Ptr): New function.
26292 (Get_TSD): Modified to access the new position of the TSD.

26306 dispatching, setting the controlling status of the formal parameters
26307 and result, and issuing an error if there is no controlling type for
26308 the formal subprogram.
26309 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
26310 which is an unclean use of that field, we set the new field
26311 Corresponding_Formal_Spec to make the formal subprogram available to

26323 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
26324 subprogram only if inner one comes from source.
26325 (Analyze_Function_Call): If the call is given in object notation, the

26327 argument list. After analyzing the name, if the call has been rewritten
26328 and the result type is set, no further analysis is needed.
26329 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
26330 mark in function specification, in a context where the formals are
26331 visible and hide outer homographs.
26333 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
26334 as the tagged type for the cases of abstract formal subprograms and
26335 renamings of those. Clean up spec comments.
26336 (Check_Dispatching_Context): Add error message to indicate "abstract
26337 procedure", covering the case of a call to a formal abstract procedure
26338 that has statically tagged operands.
26339 (Check_Dispatching_Call): Check for the case of an actual given by
26340 a tag-indeterminate function call whose type is an ancestor of the
26341 containing call's associated tagged type. This situation can occur
26342 for inherited primitives with function defaults. In this case we
26343 use the tagged type's tag directly as the controlling argument for
26345 (Expand_Call): Name change on call to Expand_Dispatch_Call.
26347 * sprint.adb (Sprint_Node_Actual): Split
26348 N_Formal_Subprogram_Declaration into two alternatives for the new

26424 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
26425 on the field if Pragma Component_Alignment (Storage_Unit).
26426 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
26427 side-effects as if it were a constant; also make SAVE_EXPR to protect

26447 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
26448 component of an array of arrays in an assignment context, and the
26449 aggregate has component associations that require sliding on
26450 assignment, force reanalysis of the aggregate to generate a temporary
26451 before the assignment.
26452 (Must_Slide): Make global to the package, for use in Gen_Assign.
26454 2005-02-09 Ed Schonberg <schonberg@adacore.com>
26456 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
26457 unchecked union with no inferable discriminants, return a
26458 Raise_Program_Error node, rather than inserting it at the point the

26470 Arnaud Charlet <charlet@adacore.com>
26472 * init.c (__gnat_initialize): Add a new parameter eh which contains the
26473 address of the exception registration. The Win32 version of this
26474 routine calls __gnat_install_SEH_handler() to initialize the SEH
26475 (Structured Exception Handling) handler.
26476 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
26477 SEH (Structured Exception Handling) now.
26478 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
26479 (__gnat_initialize for ppc-vxworks): Adjust comments and the
26480 preprocessor condition protecting the call to the extra eh setup
26481 subprogram, which is only available for the ppc target.

26495 Update copyright notice.
26497 * s-tassta.adb (Task_Wrapper): Declare the exception registration

26527 2005-02-09 Vincent Celier <celier@adacore.com>
26529 * prj-makr.adb (Process_Directory): Put file name in canonical case
26530 before matching against the patterns.
26531 If gnatname has been invoked as <prefix>-gnatname
26532 then invoke the compiler as <prefix>-gcc, not just "gcc".
26534 2005-02-09 Ed Schonberg <schonberg@adacore.com>
26536 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
26537 with expansion disabled. The actual subtype is needed among other
26538 places when the selected component appears in the context of a loop
26539 bound, and denotes a packed array.
26540 (Operator_Check): Always use the first subtype in the
26541 error message, to avoid the appearance of internal base types.
26542 (Transform_Object_Operation): Copy each actual in full
26543 to the parameter associations of the constructed call, rather than
26544 using the shallow copy mechanism of New_Copy_List. This ensures that
26545 the chaining of named associations is done properly.
26546 (Complete_Object_Operation): Rewrite node, rather than
26547 replacing it, so that we can trace back to the original selected
26550 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
26551 and calls that use object notation, if the called function is not
26552 declared in a withed unit, place the elaboration constraint on the
26553 unit in the context that makes the function accessible.
26554 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
26555 imposes an elaboration constraint between two packages.
26557 2005-02-09 Ed Schonberg <schonberg@adacore.com>
26559 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
26560 views of a private type after handling its private dependents, to

26582 Slight fix to documentation of -gnaty with no parameters
26584 * xr_tabls.ads: Add ??? comment for missing overall comment
26586 * xsinfo.adb: Make default file name be sinfo.h, since this is what
26587 we now use by default.
26589 * xsnames.adb: Adjust end of file test to look for five space followed
26590 by '#' instead of six spaces. The format of xsnames.adb was modified
26591 in the last update.
26593 * a-numeri.ads: Add reference to AI-388 for greek letter pi
26596 * clean.adb: Minor reformatting.
26598 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
26599 gnatname.adb: Minor reformatting
26600 Add 2005 to copyright output when utility is run
26602 * csets.adb: Eliminate obsolete comment
26604 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
26607 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
26609 2005-02-09 Sergey Rybin <rybin@adacore.com>
26611 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
26612 the difference between compact and incompact layout and add the record
26613 representation clause to the example illustrating different layouts.
26614 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
26615 component clauses").
26617 2005-02-09 Florian Villoing <villoing@adacore.com>
26619 * gnat_ugn.texi: Fix typos.
26620 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
26622 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"

26810 (Resolve_Access, case 'Access): Note that GNAT uses the context type to
26811 disambiguate overloaded prefixes, in accordance with AI-235. GNAT code
26812 predates, and partly motivates, the adoption of the AI.
26813 Implement new Ada 2005 attribute Mod

26867 No_Dependence restrictions.
26868 (Install_Withed_Unit): Add code to implement AI-377 and diagnose
26869 illegal context clauses containing child units of instance.
26871 * sem_prag.adb: Processing and checking for new No_Dependence

26919 2005-01-03 Olivier Hainque <hainque@adacore.com>
26921 * decl.c (compatible_signatures_p): New function. The intended purpose
26922 is to check if two function signatures for a call-site and a callee are
26923 compatible enough for the call to be valid. The underlying purpose is
26924 to check if a call to a mapped builtin is using the right interface.
26925 The current code actually does not check antyhing - this a placeholder
26926 for future refinements.

26977 structure of GARLIC and PolyORB RPC receivers.
26978 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
26980 Simplify elaboration code for RCI packages.
26982 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver
26983 generation to reduce differences between the structure of GARLIC and

27055 * sem_ch4.adb (Has_Fixed_Op): New predicate in Check_Arithmetic_Pair,
27056 to determine whether one of the operands is a fixed-point type for
27057 which a user-defined multiplication or division operation might be
27060 * sem_res.adb (Valid_Conversion): The legality rules for conversions
27061 of access types are symmetric in Ada 2005: either designated type can

27066 * s-fileio.adb (Temp_File_Record): Change length of string component
27067 Name from L_tmpnam + 1 to max_path_len + 1.

27089 porting guide chapter (vms version).
27090 Revised doc title (removed "for native platforms") and subtitle.
27091 Add discussion on warning flag for obsolescent features. First we
27092 note that it applies to obsolete GNAT features, which was previously
27093 omitted. Second we contrast the behavior with that of the new
27094 Ada 2005 AI-368 restriction No_Obsolescent_Features.
27095 Preliminary rewriting of GNAT & libraries chapter in order to take
27096 into account default project locations & new project manager

27327 "no bitfield creation", to be used by make_aligning_type. Don't
27328 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
27329 fields claimed addressable still have to be bitfields. Use
27330 value_factor_p instead of a raw binop construction to check for the
27331 position's alignment.

27338 Ed Schonberg <schonberg@adacore.com>
27340 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
27341 with an implicit dereference as its prefix, use
27342 Insert_Explicit_Dereference instead of merely rewriting the prefix into

27344 prefix is generated, if appropriate.
27346 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
27347 dereference is rewritten to an explicit one, generate a reference to
27348 the entity denoted by its prefix using the original prefix node, so

27350 access value, if appropriate.
27352 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
27353 emitting 'assigned but never read' warning on a variable on the basis

27367 an external name, to be handled by the back end.
27369 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
27370 subprogram which is Imported with convention Intrinsic if an
27371 External_Name argument is specified.
27372 (Process_Import_Or_Interface): Properly diagnose link name argument.
27373 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

27398 PolyORB_Support.Build_Stub_Type): New subrograms containing the
27399 PCS-specific part of Add_Stub_Type.

27426 (Generate_Reference): Handle properly a reference to an entry formal,
27427 when an accept statement has a pragma Unreferenced for it.
27429 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
27430 and the Has_Pragma_Unreferenced flag for each formal before analyzing
27431 the body, to ensure that warnings are properly emitted for each accept
27432 statement of a given task entry.

27454 (Remove_Next_Debug): Same fix
27456 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
27457 maintain back pointers now, though we did not used to, and comments
27459 (Prepend): Remove pragma Inline.
27460 (Remove_Next): Same cleanup
27462 2004-12-07 Thomas Quinot <quinot@adacore.com>
27464 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
27465 used to record an implicit dereference as a read operation on its
27466 prefix when operating under -gnatc. Necessary to avoid spurious
27467 'variable assigned but never read' warnings in that mode.
27468 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
27469 is a non-overloaded implicit dereference, call the above subprogram to
27470 ensure proper recording of references.
27472 2004-12-07 Gary Dismukes <dismukes@adacore.com>
27474 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
27475 to be resolved later as part of Analyze_Iteration_Scheme's call to

27522 2004-12-07 Vincent Celier <celier@adacore.com>
27524 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
27525 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
27526 and -eit to -ept. Added qualifier
27527 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
27529 2004-11-27 Andreas Schwab <schwab@suse.de>
27531 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
27533 2004-11-25 Arnaud Charlet <charlet@adacore.com>
27535 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
27536 internal implementation unit GNAT.Sockets.Thin,
27537 as their usage for sockets is non-portable (using the read and write
27538 functions from the system runtime library is fine on UNIX but won't
27539 work under Windows).

27543 2004-11-25 Arnaud Charlet <charlet@adacore.com>

27592 (Setup_Exception): Do nothing in the GNAT SJLJ case.
27594 * gigi.h (others_decl, all_others_decl): New decls representing the
27595 new Others_Value and All_Others_Value objects.
27596 (struct attrib): Rename "arg" component as "args", since GCC expects a
27597 list of arguments in there.
27599 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
27600 corresponding objects exported by a-exexpr, instead of hardcoded dummy
27603 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
27604 others_decl and all_others_decl instead of hardcoded dummy addresses
27605 to represent "others" and "all others" choices, which is cleaner and
27606 more flexible with respect to the possible eh pointer encoding policies.
27608 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
27609 (process_attributes): Account for the naming change of the "args"
27610 attribute list entry component.
27612 * decl.c (build_attr_list): Rename into prepend_attributes to allow
27613 cumulating attributes for different entities into a single list.
27614 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
27615 attributes for the current entity and propagate first subtype
27616 attributes to other subtypes.
27617 <E_Procedure>: Attribute arguments are attr->args and not
27618 attr->arg any more.
27619 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
27620 argument provided, as this is what GCC expects. Use NULL_TREE instead
27623 2004-11-18 Robert Dewar <dewar@adacore.com>
27625 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
27626 Minor reformatting througout (including new function specs)
27627 Add ??? comments asking for clarification.

27637 procedures factors the common processing for building an RPC receiver
27638 for an RCI package or an RACW type.

27643 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
27645 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
27647 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
27648 distribution subprogram identifiers that are either subprogram numbers
27650 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
27651 string distribution identifiers assigned to a given subprogram.
27652 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
27653 (Add_RAS_Dereference_TSS): Add comments.
27654 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
27655 is not referenced yet because it will be used by the PolyORB DSA
27657 (Insert_Partition_Check): Remove fossile code.
27658 (First_RCI_Subprogram_Id): Document this constant.
27659 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
27661 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
27662 replaced with calls to Get_Library_Unit_Name_String. Previously there
27663 were several instances of the same code in different locations in the
27664 compiler; this checkin completes the replacement of all of these
27665 instances with calls to a common subprogram.
27666 Minor reformatting.
27668 * sem_dist.adb: Remove comment noting that RPC receiver generation
27669 should be disabled for RACWs that implement RASs.
27670 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
27672 * sem_util.ads, sem_util.adb (Has_Stream): New function

27674 qualified name of a library unit into the name buffer.
27675 (Note_Possible_Modification): Generate a reference only
27676 if the context comes from source.
27678 * snames.ads (PCS_Names): New subtype corresponding to names of
27679 supported implementations of the Partition Communication Subsystem
27680 (PCS) (i.e. the runtime library support modules for the distributed
27683 2004-11-18 Robert Dewar <dewar@adacore.com>
27684 Ed Schonberg <schonberg@adacore.com>
27686 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
27687 (Has_Rep_Pragma): New function
27688 (Has_Attribute_Definition_Clause): New function
27689 (Record_Rep_Pragma): Moved here from sem_ch13.adb
27690 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
27692 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
27694 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
27695 (Expand_Pragma_Psect_Object): New procedure
27696 These procedures contain the revised and cleaned up processing for
27697 these two pragmas. This processing was formerly in Sem_Prag, but
27698 is more appropriately moved here. The cleanup involves making sure
27699 that the pragmas are properly attached to the tree, and that no
27700 nodes are improperly shared.
27702 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
27703 pragmas to Exp_Prag, which is more appropriate.
27704 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
27705 check for duplicates Remove use of Is_Psected flag, no longer needed.
27706 Use new Make_String_Literal function with string.
27708 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
27709 that are functions return universal values, that have to be converted
27710 to the context type.
27711 Use new Make_String_Literal function with string.
27712 (Get_Stream_Convert_Pragma): New function, replaces the use of
27713 Get_Rep_Pragma, which had to be kludged to work in this case.
27715 * freeze.adb: Use new Has_Rep_Pragma function
27717 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
27718 function with string.
27719 Use new Has_Rep_Pragma function.
27721 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
27724 2004-11-18 Robert Dewar <dewar@adacore.com>
27726 * errout.ads, errout.adb: (First_Sloc): New function
27728 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
27729 check (-gnatyx) instead of being included as a redundant construct
27732 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
27733 Style_Check_Order_Subprograms.
27735 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
27736 stylesw.adb: Add Style_Check_Xtra_Parens
27738 * usage.adb: Add line for -gnatyx (check extra parens)
27740 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
27742 2004-11-18 Ed Schonberg <schonberg@adacore.com>
27743 Robert Dewar <dewar@adacore.com>
27745 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
27746 discriminant of a constrained subtype, analyze the copy of the
27747 corresponding constraint, because in some cases it may be only
27748 partially analyzed.
27749 Removes long-lived ??? comments.
27751 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
27752 handled controlled or secondary-stack expressions within the
27753 iteration_scheme of a loop.
27755 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
27756 bounds that may contain functions calls, to prevent memory leaks when
27757 the bound contains a call to a function that uses the secondary stack.
27758 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
27759 generate temporaries for loop bounds that might contain function calls
27760 that require secondary stack and/or finalization actions.
27762 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
27763 selected component and the selector is overloadable (not just a
27764 function) treat as function call, Analyze_Call will disambiguate if
27766 (Analyze_Selected_Component): Do not generate an actual subtype for the
27767 selected component if expansion is disabled. The actual subtype is only
27768 needed for constraint checks.
27769 (Analyze_Allocator): If restriction No_Streams is set, then do
27770 not permit objects to be declared of a stream type, or of a
27771 composite type containing a stream.
27773 * restrict.ads: Remove the a-stream entry from Unit_Array, since
27774 No_Streams no longer prohibits with'ing this package.
27776 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
27777 discriminants, but the parent base has unknown discriminants, there is
27778 no discriminant constraint to inherit. Such a discrepancy can arise
27779 when the actual for a formal type with unknown discriminants is a
27780 similar private type whose full view has discriminants.
27781 (Analyze_Object_Declaration): If restriction No_Streams is set, then
27782 do not permit objects to be declared of a stream type, or of a
27783 composite type containing a stream.
27785 2004-11-18 Ed Schonberg <schonberg@adacore.com>
27787 * exp_dbug.ads: Update documentation to reflect simpler encoding for
27788 protected operations.
27790 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
27791 generated name, it complicates decoding in gdb and hinders debugging
27792 of protected operations.
27793 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
27794 flag for the protected entry barrier function.
27795 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
27796 flag for the protected entry function.

27800 * expect.c: Define __unix__ when __APPLE__ is defined.
27802 * Makefile.in: Inform the value of the variable GMEM_LIB in the
27803 Darwin-specific section.
27805 * lang-specs.h: Change the placement of the %1 marker.
27806 Works around the fact that gcc adds -fPIC by default under Darwin.
27808 2004-11-18 Ed Schonberg <schonberg@adacore.com>
27810 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
27811 type of the object with the packed array type, set the Analyzed flag
27812 on the object if it is an entity or simple indexed component, to avoid
27813 spurious type errors.
27815 2004-11-18 Gary Dismukes <dismukes@adacore.com>
27817 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
27818 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
27819 separate line from the version message.
27821 2004-11-18 Ed Falis <falis@adacore.com>
27823 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
27825 (init_float): Eliminate initialization of floating point status for
27826 AE653. The instructions have no effect for vThreads.
27828 2004-11-18 Vincent Celier <celier@adacore.com>
27830 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
27831 gnatbind is invoked with -shared.
27833 2004-11-18 Jose Ruiz <ruiz@adacore.com>
27835 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
27836 for Detect_Blocking which is redundant with the check done within the
27837 procedure Protected_Single_Entry_Call.
27838 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
27839 Detect_Blocking which is redundant with the check done within the
27840 procedure Protected_Single_Entry_Call.
27842 2004-11-18 Vincent Celier <celier@adacore.com>
27844 * makegpr.adb (Compile): Put the compiling switches (in package
27845 Compiler and on the command line) immediately after "-c", instead of
27846 at the end of the command line invocation of the compiler, when
27847 compiling a non-Ada file.
27848 (Build_Global_Archive): When there is no need to rebuild the archive,
27849 set Global_Archive_Exists, so that the archive is passed to the linker
27852 2004-11-18 Robert Dewar <dewar@adacore.com>
27853 Sergey Rybin <rybin@adacore.com>
27856 Remove extra paren check from list of checks for redundant constructs
27857 Add documentation of new -gnatyx style check (check extra parens)
27858 Remove paragraph about gnatelim debug options.
27860 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
27861 objects rather than forbidding dependencies on the package Ada.Streams.
27863 * sinfo.ads: Add ??? note that we should document pragmas passed to
27866 * g-expect.ads: Fix a few typos in the comments.
27868 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
27870 * misc.c (gnat_handle_option): Use %< and %> for quoting in
27873 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
27875 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
27877 2004-11-07 Andreas Schwab <schwab@suse.de>
27879 * Makefile.in (install-gnatlib): Remove spurious hyphen.
27881 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
27884 * Makefile.in (darwin): Set soext to .dylib.
27886 2004-10-26 Vincent Celier <celier@gnat.com>
27887 Thomas Quinot <quinot@act-europe.fr>
27889 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
27890 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
27891 there is no use of GNAT.Sockets.Constants.
27892 Remove remaining pragma Import for C_Write
27893 Remove C_Read and C_Write from internal implementation unit
27894 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
27895 the read and write functions from the system runtime library is fine
27896 on UNIX but won't work under Windows).
27898 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
27899 (Check_Selector): Use C_Recv instead of C_Read.
27900 Selectors are the GNAT.Sockets abstraction to perform a select()
27901 call on a set of descriptors. To allow abortion of an ongoing
27902 select operation, some data is written to a dedicated socket that
27903 is always monitored.
27904 Under Windows, the write and read library functions cannot operate
27905 on sockets, so we need to use send and recv instead, which is portable
27906 across all supported platforms.
27908 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
27909 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
27910 (using the read and write functions from the system runtime library is
27911 fine on UNIX but won't work under Windows).
27913 2004-10-26 Nicolas Setton <setton@act-europe.fr>
27915 * mlib-tgt-darwin.adb: New file.
27917 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
27918 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
27919 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
27920 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
27923 * Makefile.in: Add support for building shared libraries under Darwin.
27924 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
27925 the low level EH init subprogram to be called from __gnat_initialize.
27927 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
27928 indicates which options to pass to the archive indexer.
27930 * mlib-utl.adb: Add support for calling ranlib with additional
27931 options. This is needed for instance under Mac OS X.
27932 (Ranlib_Options): New global variable, used to store the potential
27933 options to pass to ranlib.
27934 (Ar): Use Ranlib_Options when spawning ranlib.
27935 (Initialize): Set the value of ranlib option.
27937 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
27939 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
27940 instead of 8K, to reflect the real potential needs for stack-checking
27943 2004-10-26 Pascal Obry <obry@gnat.com>
27945 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
27947 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
27948 Windows only the initial thread stack size can be set so it is good to
27949 start we a low stack size.
27950 The OS will adjust the size as needed.
27952 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
27953 Nicolas Setton <setton@act-europe.fr>
27955 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
27956 "__unix__" instead of "unix".
27957 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
27958 sections were just mistakenly ignored. The former is
27959 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
27960 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
27961 of hpux. This prevents an unwanted definition of the symbol
27962 convert_addresses in adaint.o.
27964 2004-10-26 Gary Dismukes <dismukes@gnat.com>
27966 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
27967 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
27969 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27971 * a-filico.ads, a-filico.adb: fix incorrect header.
27973 2004-10-26 Javier Miranda <miranda@gnat.com>
27975 * a-ststio.ads: Fix typo in identifier
27977 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27979 * sem_ch4.adb: Minor reformatting.
27981 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27983 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
27984 enabled, check the result of unary and binary operations when the
27985 expression is the right-hand side of an assignment.
27987 2004-10-26 Vincent Celier <celier@gnat.com>
27989 * clean.adb (Delete): Do not output warnings when in quiet output and
27990 not in verbose mode.
27991 (Force_Deletions): New Boolean flag, defaulted to False
27992 (Delete): Only delete a file if it is writable, and when
27993 Force_Deletions is True.
27994 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
27995 (Usage): Line for new switch -f
27996 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
27999 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
28001 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
28002 JM type only if its size matches that of the wrapper. When a size is
28003 prescribed and the field is not aliased, remove the wrapper of a JM
28004 type only if the size is not greater than that of the packed array.
28005 (gnat_to_gnu_entity): Change the extension of packed array wrappers
28008 2004-10-26 Geert Bosch <bosch@gnat.com>
28010 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
28011 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
28012 (Pred): Implement in terms of Succ.
28014 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28016 * exp_aggr.adb (Safe_Component): An aggregate component that is an
28017 unchecked conversion is safe for in-place use if the expression of the
28018 conversion is safe.
28019 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
28020 be expandable in place even if the aggregate does not come from source.
28021 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
28022 designated object of an allocator in place, rather than building it
28023 first on the stack. The previous scheme forces a full copy of the array,
28024 and may be altogether unsusable if the size of the array is too large
28025 for stack allocation.
28027 2004-10-26 Robert Dewar <dewar@gnat.com>
28029 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
28030 compares if the component is atomic.
28032 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
28033 array assignment if the component type is atomic.
28035 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28036 Eric Botcazou <ebotcazou@act-europe.fr>
28038 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
28039 is aliased and is a by_reference type, do not pass by copy.
28040 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
28041 detect whether the call is in the right side of an assignment or
28042 the expression of an object declaration. Recurse on component
28043 association within aggregates.
28044 Call it in the condition that determines whether the temporary is
28045 necessary for correct stack-checking.
28047 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28049 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
28050 RACW_Type, used in the PolyORB version.
28051 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
28052 version and the GARLIC version.
28054 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
28055 Rename RCI_Info to RCI_Locator for better consistency between the
28056 GARLIC and PolyORB versions of the distributed systems annex.
28057 (DSA_Implementation_Name): This enumeration lists the possible
28058 implementations of the Partition Communication Subsystem for the
28059 Distributed Systems Annex (DSA). The three available implementations
28060 are the dummy stub implementation (No_DSA), and two versions based on
28061 two different distribution runtime libraries: GARLIC and PolyORB. Both
28062 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
28064 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
28067 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
28068 between the GARLIC and PolyORB versions of the distributed systems
28070 Remove RE_Unbounded_Reclaim_Pool since it is unused.
28072 2004-10-26 Gary Dismukes <dismukes@gnat.com>
28074 * gnat1drv.adb: Suppress calling the back end when
28075 Frontend_Layout_On_Target is true.
28077 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28079 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
28080 Set_Read_Only): New subprograms.
28081 These new routines allow the user to set or unset the Owner execute
28082 and Owner write permission flags on a file.
28084 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
28085 GNAT.OS_Lib.Set_Executable instead of rolling our own.
28087 2004-10-26 Matthew Gingell <gingell@gnat.com>
28089 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
28091 2004-10-26 Pascal Obry <obry@gnat.com>
28093 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
28094 memory before the faulting page we properly test the process read
28095 access for this address using appropriate Win32 routine.
28096 (HPUX sections): guard with "__hpux__" instead of "hpux".
28098 2004-10-26 Robert Dewar <dewar@gnat.com>
28100 * lib-xref.adb (Generate_Reference): Don't complain about reference to
28101 entry parameter if pragma Unreferenced set, since we do not properly
28102 handle the case of multiple parameters.
28104 2004-10-26 Vincent Celier <celier@gnat.com>
28106 * prj-env.adb: (Contains_ALI_Files): New Boolean function
28107 (Ada_Objects_Path.Add): For a library project, add to the object path
28108 the library directory only if there is no object directory or if the
28109 library directory contains ALI files.
28110 (Set_Ada_Paths.Add.Recursive_Add): Ditto
28112 2004-10-26 Vincent Celier <celier@gnat.com>
28114 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
28115 extension of library projects.
28117 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
28118 path defaults to ".:<prefix>/lib/gnat".
28119 (Parse): For an extending all project, allow direct import of a project
28120 that is virtually extended.
28122 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
28123 the specified name is directly imported, return its ID. Otherwise, if
28124 an extension of this project is imported, return the ID of the
28127 2004-10-26 Robert Dewar <dewar@gnat.com>
28129 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
28130 (Sub3): New procedure, used by Scaled_Divide
28131 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
28132 correct more than one instance of failure to propagate carries
28134 (Double_Divide): Handle overflow case of largest negative number
28135 divided by minus one.
28137 * s-arit64.ads (Double_Divide): Document that overflow can occur in
28138 the case of a quotient value out of range.
28141 2004-10-26 Robert Dewar <dewar@gnat.com>
28143 * s-bitops.adb (Bit_Eq): Remove redundant check.
28145 * s-bitops.ads: Minor comment updates
28146 Change some occurrences of Address to System.Address
28148 * s-carsi8.ads: Fix minor cut-and-paste error in comments
28150 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28152 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
28153 accessibility check to prefix that is a protected operation.
28155 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28157 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
28158 empty, post message on stub.
28160 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28161 Javier Miranda <miranda@gnat.com>
28163 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
28164 current instance appears within a unit that is directly in the context
28166 Used to determine whether the body of the instance should be analyzed
28167 immediately after its spec, to make its subprogram bodies available
28168 for front-end inlining.
28169 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
28170 constraint is not allowed on the component type (AARM 12.5.3(3))
28172 2004-10-26 Cyrille Comar <comar@act-europe.fr>
28174 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
28175 'Storage_Pool): enhance, document & limit detection of non-sharable
28178 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
28180 * s-pooglo.ads: Add more documentation now that this pool is properly
28183 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28185 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
28186 or protected type with discriminants, do not constrain the
28187 corresponding record type if the subtype declaration has no
28188 discriminant constraints. This can be the case in source code, or in
28189 the subtype declaration created to rename an actual type within an
28192 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28194 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
28195 different kind of stub (possibly wrong name for file), do not check
28197 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
28198 includes call to some function that returns an unconstrained type, do
28201 2004-10-26 Ed Schonberg <schonberg@gnat.com>
28203 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
28204 appear in the code for the main unit. Dependencies among units in the
28205 context of the main unit are established when those other units are
28206 compiled. Otherwise spurious elaboration constraints can generate
28207 incorrect elaboration circularities.
28209 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
28210 Ed Schonberg <schonberg@gnat.com>
28212 * sem_util.adb (Is_Aliased_View): Defend against the case where this
28213 subprogram is called with a parameter that is not an object name. This
28214 situation arises for some cases of illegal code, which is diagnosed
28215 later, and in this case it is wrong to call Is_Aliased, as that might
28216 cause a compiler crash.
28217 (Explain_Limited_Type): Refine previous fix to include
28218 inherited components of derived types, to provide complete information.
28220 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
28221 is the prival for a protected object.
28222 It is necessary to mark this entity as a variable, in addition to
28223 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
28224 modified to avoid checking the Aliased flag on entities that are not
28225 objects. (Checking that flag for non-objects is erroneous and could
28226 lead to a compiler crash).
28228 2004-10-26 Robert Dewar <dewar@gnat.com>
28230 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
28231 X_Frac = 0.5, then we know that the number X must be positive.
28232 (Succ): Remove the same redundant test, and also fix the primary test
28233 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
28235 (Decompose): Add fuller comments to spec
28237 2004-10-26 Pascal Obry <obry@gnat.com>
28239 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
28240 validity (process must have read access). Set to 0 in all other cases.
28241 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
28242 violation on Win32.
28243 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
28244 segmentation violation.
28246 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
28248 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
28249 whose type is a constructed subtype of an aliased object with an
28250 unconstrained nominal subtype, convert the actual to the constructed
28251 subtype before taking its address.
28253 2004-10-26 Vincent Celier <celier@gnat.com>
28255 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
28256 (Is_Path_Name_Case_Sensitive): New function
28258 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
28259 (Base_Name, Simple_Name, Current_Directory, Compose,
28260 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
28263 2004-10-26 Cyrille Comar <comar@act-europe.fr>
28264 Vasiliy Fofanov <fofanov@act-europe.fr>
28265 Vincent Celier <celier@gnat.com>
28267 * gnat_ugn.texi: Generalize "finding memory problems" section into a
28268 "memory management issues" section and document some of the useful
28269 memory pools provided as part of the GNAT library.
28270 Remove "virtual" from declaration of A::method2 in
28271 the simple example of Ada/C++ mixed system.
28272 Library Projects may be virtually extended: their virtual extensions
28273 are not Library Projects.
28274 Added section on extending project hierarchies.
28276 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
28278 * adaint.c (__gnat_get_libraries_from_registry): Cast value
28280 (__gnat_portable_spawn): Remove const.
28282 * mingw32.h (MAXPATHLEN): Check for previous definition.
28284 2004-10-17 Matthias Klose <doko@debian.org>
28286 * gnatvsn.ads: Set gnat library version to 4.0.
28288 2004-10-05 Vincent Celier <celier@gnat.com>
28290 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
28292 2004-10-04 Laurent Guerby <laurent@guerby.net>
28295 * Makefile.in: Define and use RANLIB_FLAGS.
28297 2004-10-04 Pascal Obry <obry@gnat.com>
28299 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
28300 other x86 platforms).
28302 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
28304 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
28305 in general and triggers stack alignment adjustment for thread entry
28306 points on targets where this is necessary.
28308 2004-10-04 Bernard Banner <banner@gnat.com>
28311 * Makefile.in: Add section for powerpc linux
28312 Add variant i-vxwork-x86.ads
28314 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
28316 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
28318 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
28319 table registration calls when need be. Ensures no reference to the crt
28320 ctors symbol are issued in the SJLJ case, which avoids possible
28321 undefined symbol errors in the case of modules to be statically linked
28324 2004-10-04 Javier Miranda <miranda@gnat.com>
28326 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
28327 in-line the code corresponding to subprogram Analyze_Actuals. In
28328 addition, analyze the actuals only in case of subprogram call.
28330 2004-10-04 Ed Falis <falis@gnat.com>
28332 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
28334 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
28336 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
28337 in the documentation.
28339 2004-10-04 Robert Dewar <dewar@gnat.com>
28341 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
28343 (Analyze_Block_Statement): Add circuitry to detect following dead code
28344 (Check_Unreachable_Code): Handle case of block exit
28346 2004-10-04 Robert Dewar <dewar@gnat.com>
28348 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
28349 (XMatchD): Avoid warning for Logic_Error call
28351 2004-10-04 Robert Dewar <dewar@gnat.com>
28353 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
28354 consider expressions buried within a procedure actual to be an actual.
28355 This caused some blowups with uses of packed slices within a procedure
28358 2004-10-04 Robert Dewar <dewar@gnat.com>
28360 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
28361 longer need to be initialized to zero.
28362 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
28363 initialized to zero.
28365 * checks.adb (Expr_Known_Valid): Packed arrays are now always
28366 considered valid, even if the representation is modular. That's correct
28367 now that we no longer initialize packed modular arrays to zero.
28369 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
28370 suffixes. These are now documented as the only cases in which the
28371 debugger ignores outer records.
28372 Previously, the spec allowed arbitrary suffixes for this purpose.
28373 Change name of LJM to JM for packed array pad records
28374 Create separate section on packed array handling, and add a whole new
28375 set of comments to this section describing the situation with packed
28376 modular types and justification requirements depending on endianness.
28378 2004-10-04 Robert Dewar <dewar@gnat.com>
28380 * a-except.adb: Add a comment for last change
28382 * einfo.ads: Minor spelling correction in comment
28384 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
28386 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
28389 * sem_util.ads: Minor comment update
28391 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28393 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
28394 Inline_Always when in Configurable_Run_Time mode.
28396 * sem_prag.adb (Process_Convention): If entity is an inherited
28397 subprogram, apply convention to parent subprogram if in same scope.
28398 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
28399 when in Configurable_Run_Time mode.
28401 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28403 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
28404 class_wide type after component list has been inherited.
28406 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28408 * sem_ch12.adb (Check_Generic_Actuals): New predicate
28409 Denotes_Previous_Actual, to handle properly the case of a private
28410 actual that is also the component type of a subsequent array actual.
28411 The visibility status of the first actual is not affected when the
28412 second is installed.
28413 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
28414 make fully recursive the treatment of formals of packages declared
28416 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
28417 the above on exit from an instantiation.
28418 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
28419 current instantiation which is now complete.
28420 (Analyze_Package_Instantiation): No instantiated body is needed if the
28421 main unit is generic. Efficient, and avoid anomalies when a instance
28422 appears in a package accessed through rtsfind.
28424 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28426 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
28427 do not generate a declaration for a temporary if the call is part of a
28428 library-level instantiation.
28430 2004-10-04 Ed Schonberg <schonberg@gnat.com>
28432 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
28433 searching for a limited component to flag.
28435 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
28436 expansion of Input, to account for the fact that the implicit call
28437 generated by the attribute reference must freeze the user-defined
28438 stream subprogram. This is only relevant to 'Input, because it can
28439 appear in an object declaration, prior to the body of the subprogram.
28441 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
28442 expansion can proceed and further errors uncovered.
28443 (Minor clean up): Fix cases of using | instead of \ for continuation
28446 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28448 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
28450 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
28451 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
28452 Use gcc_assert and gcc_unreachable.
28454 * decl.c (gnat_to_gnu_entity, case object): Check and process a
28455 specified alignment before validating size.
28456 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
28457 stripped-down declaration for the type of the inner field when making
28460 * utils.c (finish_record_type): Do not compute the size in units
28461 incrementally. Instead compute it once for the rep clause case.
28462 Use gcc_assert and gcc_unreachable.
28464 2004-10-04 Vincent Celier <celier@gnat.com>
28466 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
28468 (Is_Valid_Path_Name): Take '/' as a directory separator.
28470 2004-10-04 Vincent Celier <celier@gnat.com>
28472 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
28473 (Extended_Project) only if Extended_Project is defined, to avoid
28475 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
28477 (Parse_Single_Project): Ditto.
28479 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
28480 Add_To_Project_Path for virtual projects.
28482 2004-10-04 Vincent Celier <celier@gnat.com>
28484 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
28485 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
28486 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
28487 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
28488 parameter Options_2.
28490 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
28491 Build_Dynamic_Library with an empty Options_2.
28493 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
28496 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
28497 directory separator, if any.
28498 (Gprmake): Do not allow mains on the command line for library projects.
28499 Do not attempt to link when the project is a library project.
28500 (Library_Opts): New table to store Library_Options.
28501 (Build_Library): If Library_Options is specified, pass these options
28502 when building a shared library.
28504 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
28506 * s-tposen.adb (Service_Entry): The object must be always unlocked at
28507 the end of this procedure now that the unlock operation was inserted
28510 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
28512 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
28513 corresponding to the Preallocated_Stacks flags in System.
28514 (Get_Target_Parameters): Including the processing for
28515 Preallocated_Stacks.
28517 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
28518 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

28525 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
28526 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
28527 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
28528 used to signal whether the compiler creates the required stacks and
28529 descriptors for the different tasks (when True) or it is done by the
28530 underlying operating system at run time (when False).
28531 It is initially set to False in all targets.
28533 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
28534 if it is supported by the target.
28535 (Make_Task_Create_Call): Pass the stack address if it has been
28536 previously created. Otherwise pass a Null_Address.
28538 * snames.adb: Add _stack.
28540 * snames.ads: Add Name_uStack. Required to allow the expander to
28541 statically allocated task stacks.
28543 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
28544 Stack_Address argument.
28545 Check that its value is equal to Null_Address because this target does
28546 not support the static stack allocation.
28548 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
28550 * usage.adb: Change "pragma inline" to "pragma Inline" in information
28553 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
28555 * exp_dist.adb: Split declaration of asynchronous flag out of
28556 Add_RACW_Read_Attribute.
28557 Minor reformatting for better alignment with PolyORB version.
28558 Store the entity for the asynchronous flag of an RACW, rather than the
28559 expression, in the asynchronous flags table. This will allow this flag
28560 to be used in other subprograms beside Add_RACW_Read_Attribute.
28562 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
28564 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
28565 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
28566 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
28567 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
28568 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
28569 sockets constant MSG_NOSIGNAL (Linux-specific).
28570 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
28571 all Send operations.
28572 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
28573 from trigerring SIGPIPE.
28574 Rename components to avoid clash with Ada 2005 possible reserved
28576 (Check_Selector): When the select system call returns with an error
28577 condition, propagate Socket_Error to the caller.
28579 2004-10-01 Jan Hubicka <jh@suse.cz>
28581 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
28583 2004-09-23 Robert Dewar <dewar@gnat.com>
28586 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
28587 instead do this at freeze time (we won't do it if there is an address
28589 Change "pragma inline" to "pragma Inline" in information and error
28591 Minor reformatting.
28593 * freeze.adb (Check_Address_Clause): Remove previous change, not the
28594 right way of doing things after all.
28595 (Freeze_Entity): For object, set Is_Public for imported entities
28596 unless there is an address clause present.
28598 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
28600 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
28601 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
28602 ensures proper handling of types with rep clauses, which might have
28603 their TYPE_SIZE set already.
28605 2004-09-21 Robert Dewar <dewar@gnat.com>
28607 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
28608 packed array types in both little- and big-endian cases. This change
28609 ensures that we no longer count on the unused bits being initialized
28610 for such types (and in particular ensures that equality testing will
28611 only read the relevant bits).
28612 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
28613 These changes mean that we no longer need to initialize small packed
28615 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
28616 optimization to an LJM field as to its parent field.
28618 * ada-tree.h, trans.c, utils.c, utils2.c:
28619 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
28621 2004-09-20 Jan Hubicka <jh@suse.cz>
28623 * utils.c (gnat_finalize): Remove.
28624 (end_subprog_body): Directly call cgraph_finalize_function;
28625 do not lower the nested functions.
28627 2004-09-20 Robert Dewar <dewar@gnat.com>
28630 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public

28745 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
28746 the protected action nesting level.
28747 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
28748 protected action nesting level.
28749 (Unlock): When pragma Detect_Blocking is active decrease the protected
28750 action nesting level.
28752 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
28753 Protected_Action_Nesting.
28755 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
28756 Common_ATCB record. It contains the dynamic level of protected action
28757 nesting for each task. It is needed for checking whether potentially
28758 blocking operations are called from protected operations.
28759 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
28760 Detect_Blocking is active or not in the partition.
28762 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

28796 contains the required machinery for handling that.
28798 * sem_util.ads: Change comment associated to procedure
28799 Check_Potentially_Blocking_Operation.
28800 This procedure does not insert a call for raising the exception because
28801 that is currently done by the run time.
28803 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
28805 * init.c: Add the global variable __gl_detect_blocking that indicates
28806 whether pragma Detect_Blocking is active (1) or not (0). Needed for
28807 making the pragma available at run time.
28808 (__gnat_set_globals): Pass and update the detect_blocking parameter.

28815 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
28816 DB is found in the ali file. Any unit compiled with pragma
28817 Detect_Blocking active forces its effect in the whole partition.
28819 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
28820 Detect_Blocking is active and delay is called from a protected
28823 * bindgen.adb (Gen_Adainit_Ada): When generating the call to

28837 (Register_Receiving_Stub): Add Subp_Info formal parameter.
28838 Update API in placeholder implemetation of s-parint to reflect changes
28839 in distribution runtime library.
28841 * sem_ch3.adb (Expand_Derived_Record): Rename to
28842 Expand_Record_Extension.
28844 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
28845 primitive operations of potentially distributed object types that have
28846 non-controlling anonymous access formals.
28848 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
28850 New implementation of expansion for remote access-to-subprogram types,
28851 based on the RACW infrastructure.
28852 This version of sem_dist is compatible with PolyORB/DSA as well as
28855 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
28856 Asynchrronous that applies to a remote access-to-subprogram type, mark
28857 the underlying RACW type as asynchronous.
28859 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
28860 __gnat_using_gnu_linker to 1.

28869 * exp_ch3.adb (Expand_Derived_Record): Rename to
28870 Expand_Record_Extension.
28871 (Build_Record_Init_Proc.Build_Assignment): The default expression in
28872 a component declaration must remain attached at that point in the
28873 tree so New_Copy_Tree copies it if the enclosing record type is derived.
28874 It is therefore necessary to take a copy of the expression when building
28875 the corresponding assignment statement in the init proc.
28876 As a side effect, in the case of a derived record type, we now see the
28877 original expression, without any rewriting that could have occurred
28878 during expansion of the ancestor type's init proc, and we do not need
28879 to go back to Original_Node.
28881 * exp_ch3.ads (Expand_Derived_Record): Rename to
28882 Expand_Record_Extension.

28889 subprogram. The proxy object is used as the designated object
28890 for RAS values on the same partition (unless All_Calls_Remote applies).
28891 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
28892 System.Partition_Interface.Get_Unique_Remote_Pointer.

28897 New implementation of expansion for remote access-to-subprogram types,
28898 based on the RACW infrastructure.
28900 * exp_dist.ads (Copy_Specification): Update comment to note that this
28901 function can copy the specification from either a subprogram
28902 specification or an access-to-subprogram type definition.
28904 2004-09-09 Ed Schonberg <schonberg@gnat.com>
28906 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
28907 in an instance, between an explicit subprogram an one inherited from a
28908 type derived from an actual.
28910 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
28911 add a polling call if the subprogram is to be inlined by the back-end,
28912 to avoid repeated calls with multiple inlinings.
28914 * checks.adb (Apply_Alignment_Check): If the expression in the address
28915 clause is a call whose name is not a static entity (e.g. a dispatching
28916 call), treat as dynamic.

28920 * g-trasym.ads: Minor reformatting
28922 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

28934 enable map file generation. Add the right option to generate the map
28935 file if Map_File is set to True.
28937 * gnatdll.adb (Gen_Map_File): New variable.
28938 (Syntax): Add info about new -m (Map_File) option.

28966 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
28967 of variable length temporaries for function return now that the
28968 back-end and gigi support it.

29048 2004-09-01 Vincent Celier <celier@gnat.com>
29050 * bindgen.adb: (Set_EA_Last): New procedure

29162 for a global aliased object with a variable size and an unconstrained
29163 nominal subtype, pretend there is no initializer if the one we have is
29164 incomplete, and avoid referencing an inexistant component in there. The
29165 part we have will be rebuilt anyway and the reference may confuse

29189 unit, this is an attempt to inline a construct that is not available in
29190 the current restricted mode, so abort rather than trying to continue.
29192 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
29193 discriminants that rename those of the parent, recover names of
29194 original discriminants for the constraint on the full view of the

29224 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
29225 returning C.int, to avoid using a derived boolean type.
29227 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
29228 Duplicate_Subexpr_No_Checks in preference to direct use of

29256 ignore overflows on low and high bounds of an index to also account for
29257 differences in signedness between sizetype and gnu_index_subtype.
29258 These are as legitimate as the ones caused by a lower TYPE_PRECISION

31579 2004-05-14 Robert Dewar <dewar@gnat.com>
31581 * gnat_ugn.texi: Minor change to -gnatS documentation
31583 * sprint.adb: Remove some instances of Assert (False) and for this
31584 purpose replace them by output of a ??? string.
31586 * checks.adb, exp_aggr.adb, sem_elim.adb: Remove useless pragma
31589 * lib-writ.adb, lib-load.adb, lib.ads, lib.adb: Remove Dependent_Unit
31590 flag processing. This was suppressing required dependencies in
31591 No_Run_Time mode and is not needed since the binder does not generate
31592 references for things in libgnat anyway.
31594 * sem_ch3.adb (Access_Type_Declaration): Reorganize code to avoid GCC
31597 2004-05-14 Thomas Quinot <quinot@act-europe.fr>
31599 * gnat_ugn.texi: Document AIX-specific issue with initialization of
31602 * exp_ch4.adb (Insert_Dereference_Action): Do not generate dereference
31603 action for the case of an actual parameter in an init proc call.
31605 2004-05-14 Ed Schonberg <schonberg@gnat.com>
31607 * sem_ch4.adb (Analyze_Selected_Component): If prefix is a protected
31608 subtype, check visible entities in base type.
31610 * exp_ch7.adb (Clean_Simple_Protected_Objects): Do not generate cleanup
31611 actions if the object is a renaming.
31613 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
31614 Check_Formal_Package_Instance, to determine more precisely when the
31615 formal and the actual denote the same entity.
31617 2004-05-14 Javier Miranda <miranda@gnat.com>
31619 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
31621 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
31622 corresponding to a private_with must be removed from visibility; it
31623 will be made visible later, just before we analyze the private part of
31625 (Check_Private_Child_Unit): Allow private_with clauses in public
31627 (Install_Siblings): Make visible the private entities of private-withed
31629 (Install_Withed_Unit): Do not install the private withed unit if we
31630 are compiling a package declaration and the Private_With_OK flag was
31631 not set by the caller. These declarations will be installed later,
31632 just before we analyze the private part of the package.
31634 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
31635 during the evaluation of the expression that initializes the object,
31636 decorate it with the expected type to avoid cascade errors.
31639 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
31640 subprogram we have to install the private_with clauses after its
31641 specification has been analyzed (as documented in AI-262.TXT).
31643 * sem_ch8.adb (Has_Private_With): New function. Determines if the
31644 current compilation unit has a private with on a given entity.
31645 (Find_Direct_Name): Detect the Beaujolais problem described in
31648 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
31649 provides the functionality of the function Is_Ancestor that was
31650 previously available in sem_ch10. It has been renamed to avoid
31653 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
31655 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
31657 * utils.c (build_vms_descriptor): Use SImode pointers.
31659 2004-05-14 Vasiliy Fofanov <fofanov@act-europe.fr>
31661 * gnat_ugn.texi: Revised chapter "GNAT and Libraries".
31663 2004-05-14 GNAT Script <nobody@gnat.com>
31665 * Make-lang.in: Makefile automatically updated
31667 2004-05-14 Arnaud Charlet <charlet@act-europe.fr>
31669 Renaming of target specific files for clarity

31813 * trans.c (gnat_stabilize_reference_1): Remove case 'b'.
31815 2004-05-13 Diego Novillo <dnovillo@redhat.com>
31817 Merge from tree-ssa-20020619-branch.
31819 * config-lang.in (boot_language, build_by_default): Set
31821 * utils.c (unchecked_convert): Use OEP_ONLY_CONST.
31822 (max_size): Add static chain op for call_expr.
31824 2004-05-12 Richard Sandiford <rsandifo@redhat.com>
31827 * 5gmastop.adb (Roff): Choose between '4' and '0', not '4' and ' '.
31829 2004-05-11 Roger Sayle <roger@eyesopen.com>
31831 * utils.c (max_size): Use MIN_EXPR to find the minimum value of a
31834 2004-05-10 Doug Rupp <rupp@gnat.com>
31836 * 5qsystem.ads: Remove Short_Address subtype declaration. Moved to
31839 * s-auxdec.ads: Add Short_Address subtype (moved here from System).
31841 * Makefile.in: [VMS]: Add translation for 5qauxdec.ads.
31843 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
31844 Fixes undefined symbols in IA64 gnatlib.
31846 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
31848 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
31849 Short_Address). This will be moved to system.auxdec.
31851 2004-05-10 Thomas Quinot <quinot@act-europe.fr>
31853 * sem_util.adb: Replace test for presence of a node that is always
31854 present with a call to Discard_Node.
31856 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
31857 Analyze on the library unit node after generation of distribution stub
31858 constructs. The call was a no-op because Unit_Node has already been
31859 Analyzed, and the tree fragments for the distribution stubs are
31860 analyzed as they are inserted in Exp_Dist.
31861 Update comment regarding to distribution stubs to reflect that we
31862 do not generate stub in separate files anymore.
31864 * einfo.ads: Clarify the fact that a tagged private type has the
31865 E_Record_Type_With_Private Ekind.
31867 * erroutc.adb: Minor reformatting
31869 * erroutc.ads (Max_Msg_Length): Increase to cover possible larger
31870 values if line length is increased using -gnatyM (noticed during code
31873 * eval_fat.adb: Minor reformatting
31874 Put spaces around exponentiation operator
31876 2004-05-10 Ed Schonberg <schonberg@gnat.com>
31879 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): If prefix
31880 has been rewritten as an explicit dereference, retrieve type of
31881 original node to check for possibly unconstrained record type.
31883 2004-05-10 Ed Schonberg <schonberg@gnat.com>
31885 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
31886 overriding, use the operation of the parent unconditionally.
31888 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
31889 operation when either operand is a literal, to avoid further
31892 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
31893 overridden by a previous explicit declaration, mark the previous entity
31896 * sem_disp.adb (Check_Dispatching_Operation): New predicate
31897 Is_Visibly_Controlled, to determine whether a declaration of a
31898 primitive control operation for a derived type overrides an inherited
31899 one. Add warning if the explicit declaration does not override.
31901 2004-05-10 Vincent Celier <celier@gnat.com>
31903 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
31904 some cases when the sources are no longer present.
31906 * make.adb (Collect_Arguments): Fail if an external source, not part
31907 of any project need to be compiled, when switch -x has not been
31910 * makeusg.adb: Document new switch -x
31912 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
31913 defaulted to False.
31915 * switch-m.adb (Scan_Make_Switches): New switch -x
31917 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
31918 gnatmake switch -x.
31920 * gnat_ugn.texi: Document new gnatmake switch -x
31922 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
31924 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
31926 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
31927 (process_attributes): Likewise.
31929 2004-05-10 Joel Brobecker <brobecker@gnat.com>
31931 * s-inmaop.ads: Fix spelling mistake in one of the comments.
31933 2004-05-10 Robert Dewar <dewar@gnat.com>

33030 * sem_prag.adb (Set_Exported): Warn about making static as result of
33031 export only when the export is coming from source. This may be not
33032 be true e.g. on VMS where we expand export pragmas for exception codes
33033 together with imported or exported exceptions, and we don't want the
33034 user to be warned about something he didn't write.
33036 2004-04-08 Thomas Quinot <quinot@act-europe.fr>
33038 * sem_util.adb (Note_Possible_Modification): Reorganize to remove code
33039 duplication between normal entities and those declared as renamings.

33139 specified radix_digits is greater or equal to machine_mantissa.
33141 2004-04-05 Javier Miranda <miranda@gnat.com>
33143 * par-ch3.adb: Complete documentation of previous change
33144 Correct wrong syntax documentation of the OBJECT_DECLARATION rule

33169 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
33170 statement whose right-hand side is an inlined call, save a copy of the
33171 original assignment subtree to preserve enough consistency for
33172 Analyze_Assignment to proceed.
33174 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
33175 complete assignment subtree which is now unnecessary, as the expansion
33176 of inlined call has been improved to preserve a consistent assignment
33177 tree. Note_Possible_Modification must be called only
33178 after checks have been applied, or else unnecessary checks will
33181 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
33182 of explicit dereferences that do not Come_From_Source:
33183 - be selective on cases where we must go back to the dereferenced
33184 pointer (an assignment to an implicit dereference must not be
33185 recorded as modifying the pointer);
33186 - do not rely on Original_Node being present (Analyze_Assignment
33187 calls Note_Possible_Modification on a copied tree).
33189 * sem_warn.adb (Check_References): When an unset reference to a pointer
33190 that is never assigned is encountered, prefer '<pointer> may be null'

33260 a string literal, create a temporary for it, constant folding only
33261 handles scalars here.
33263 2004-04-01 Vincent Celier <celier@gnat.com>

33447 2004-03-29 Ed Schonberg <schonberg@gnat.com>
33449 * exp_ch6.adb (Expand_Call): A call to a function declared in the
33450 current unit cannot be inlined if it appears in the body of a withed
33451 unit, to avoid order of elaboration problems in gigi.
33453 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
33454 information for protected (wrapper) operation as well, to simplify gdb
33457 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
33458 protected body, indicate that the entity for the generated spec comes

33500 a classwide type (for which Is_Object_Reference holds), but it can
33501 also be a value conversion for an access-to-classwide type. In the
33502 latter case, there is an implicit dereference, and the original node
33503 for the prefix does not verify Is_Object_Reference.

33531 value expressions to ensure that calls within a component definition
33532 will be checked (since those are evaluated during the record type's
33535 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>

33579 case when the source contains only comments.
33581 2004-03-22 Ed Schonberg <schonberg@gnat.com>
33583 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
33584 declaration for a child subprogram body that acts as a spec, indicate
33585 that the entity in the declaration needs debugging information.
33587 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
33588 full view if the subtype is created for a constrained record component;
33589 gigi has enough information to construct the record, and there is no
33590 place in the tree for the declaration.
33592 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
33593 serial number for the dummy body that is built for analysis, to avoid
33594 inconsistencies in the generation of internal names when compiling
33597 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
33599 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
33602 2004-03-22 GNAT Script <nobody@gnat.com>

33631 Minor reformatting.
33633 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
33635 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
33636 as regular exception objects and not as mere integers representing the
33637 condition code. The latter approach required some dynamics to mask off
33638 severity bits, which did not fit well into the GCC table based model.
33639 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
33640 exception data objects. We don't it and it would conflict with the other
33641 external symbol we have to generate for such exceptions.
33643 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
33644 the special code for VMS exceptions, since these are now represented
33645 as regular exceptions objects.
33647 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
33649 * decl.c (debug_no_type_hash): Remove.

33653 2004-03-19 Laurent Guerby <laurent@guerby.net>
33655 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
33656 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
33658 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
33660 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.

33662 (TYPE_RM_SIZE_INT): Directly use type.values.
33663 (TREE_LOOP_ID): Clean up check.
33664 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
33665 TYPE_VALUES, not TYPE_FIELDS.

33678 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
33680 * adaint.c: Update comments.
33682 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
33683 GNATLIB_SHARED for FreeBSD.
33685 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
33687 * init.c [VxWorks]: Do not fix the stack size for the environment task.
33688 When needed (stack checking) the stack size is retrieved
33689 from the VxWorks kernel.
33691 * Makefile.in: Flag -nostdinc is required when building the run time
33692 for avoiding looking for files in the base compiler.
33693 Add the VxWorks specific version of the package body for
33694 System.Stack_checking.Operations (5zstchop.adb).
33696 * Make-lang.in: Add the object file for
33697 System.Stack_Checking.Operations.

33704 * s-stache.ads, s-stache.adb: Move the operations related to stack
33705 checking from this package to package System.Stack_Checking.Operations.
33706 This way, stack checking operations are only linked in the final
33707 executable when using the -fstack-check flag.
33709 2004-03-18 Doug Rupp <rupp@gnat.com>
33711 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

33721 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
33722 the procedures Add_To_Path_File.
33723 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
33724 making sure that each directory is present only once and, for object
33725 dirs, when a directory already present is added, the duplicate is
33726 removed and the directory is always put as the last in the table.
33727 Write the path files at the end of these accumulations.
33729 * prj-nmsc.adb (Record_Source): Add source file name in hash table
33730 Files_Htable for all sources.
33732 * prj-proc.adb (Process): Remove restrictions between not directly
33733 related extending projects.

33741 parameter Trusted_Mode.
33743 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
33745 * scn.adb (Determine_License): Take into account a degenerated case
33746 when the source contains only comments.
33748 2004-03-18 Ed Schonberg <schonberg@gnat.com>
33750 * sem_warn.adb (Check_References): For a warning on a selected
33751 component that does not come from source, locate an uninitialized
33752 component of the record type to produce a more precise error message.
33754 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
33756 * 3zsoccon.ads: Fix multicast options.
33758 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
33761 2004-03-15 Robert Dewar <dewar@gnat.com>
33763 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
33764 pragma used for a private type.
33766 * lib-xref.adb (Generate_Reference): Do not generate warning if
33767 reference is in a different unit from the pragma Unreferenced.
33769 * 5vtpopde.adb: Minor reformatting
33770 Fix casing of To_Task_ID
33772 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
33773 flag if we have an unchecked conversion to an access type in the same
33776 2004-03-15 Geert Bosch <bosch@gnat.com>
33778 * a-ngcoty.adb (Modulus): In alternate formula for large real or
33779 imaginary parts, use Double precision throughout.
33781 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
33782 we want to be able to compile run-time with -gnata for testing, but
33783 this may also be instantiated in user code that is compiled with -gnata.
33785 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
33787 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
33788 codes. Having a separate type for this is useful to enforce consistency
33789 throughout the various run-time units.
33790 (Exception_Data): Use Exception_Code for Import_Code.
33792 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
33793 Natural and Integer in various places.

33795 with the severity bits masked off.
33796 (Register_VMS_Exception): Handle the additional exception data pointer

33800 component, now reflected by an exported accessor.
33801 (is_handled_by): New routine to compute whether the propagated
33802 occurrence matches some handler choice specification. Extracted out of
33803 get_action_description_for, and expanded to take care of the VMS
33805 (get_action_description_for): Use is_handled_by instead of an explicit
33806 complex condition to decide if the current choice at hand catches the
33807 propagated occurrence.
33809 * raise.h (Exception_Code): New type for C.
33811 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
33812 System.Standard_Library.Exception_Code, to allow references from the
33813 pragma import/export expander.
33815 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
33816 New accessors to allow easy access to GNAT exception data
33818 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
33819 redundant Handled_By_Others component, helper for the personality
33820 routine which will now be able to call the appropriate exception data
33823 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
33824 component of Standard_Exception_Type to be the closest possible to
33825 Exception_Code in System.Standard_Library, that we cannot get at this
33826 point. Expand a ??? comment to notify that this type node should
33827 probably be rewritten later on.
33829 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
33830 registration call to include a pointer to the exception object in the
33833 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
33834 instead of int and explicit bitmasks.
33836 2004-03-15 Vincent Celier <celier@gnat.com>
33838 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
33839 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
33841 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
33842 longer needed now that it is in the spec of
33843 System.Tasking.Task_Attributes.
33845 * adaint.h, adaint.c: (__gnat_create_output_file): New function
33847 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
33849 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
33851 * make.adb (Gnatmake): Do not check the executable suffix; it is being
33852 taken care of in Scan_Make_Arg.
33853 (Scan_Make_Arg): Add the executable suffix only if the argument
33854 following -o, in canonical case, does not end with the executable
33855 suffix. When in verbose mode and executable file name does not end
33856 with executable suffix, output the executable name, in canonical case.
33858 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
33859 to avoid warnings when instantiating Ada.Task_Attributes.
33862 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
33863 in the correct order.
33865 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
33866 redirect standard output and error to a file for the invocation of the
33867 compiler, then read the file.

33870 directory, instead of the Value.
33871 (Find_Source_Dirs): Remove useless code & comments.
33873 2004-03-15 Ed Schonberg <schonberg@gnat.com>
33875 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
33876 tagged type is inherited, and the parent operation is not frozen yet,
33877 force generation of a freeze node for the inherited operation, so the
33878 corresponding dispatch entry is properly initialized.
33879 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
33880 when looking for user-defined equality operation.
33882 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
33883 boolean when locating primitive equality of tagged component.
33885 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
33886 bit-aligned field and the right-hand side a string literal, introduce
33887 a temporary before expanding assignment into a loop.
33889 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
33890 priority in full, to ensure that any expanded subepxressions of it are
33891 elaborated in the scope of the init_proc.
33893 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
33894 after object declaration, skipping over code that may have been
33895 generated for validity checks.
33897 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
33898 discriminants, ignore the known discriminants of its full view, if
33899 any, to check legality.
33901 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
33902 component if type has unknown discriminants.
33903 (Analyze_Private_Extension_Declaration): Discriminant constraint is
33904 null if type has unknown discriminants.
33906 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
33907 for end label when present.
33909 * s-fileio.adb (Open): When called with a C_Stream, use given name for
33910 temporary file, rather than an empty string.
33912 2004-03-15 Ed Falis <falis@gnat.com>
33914 * s-thread.adb: Removed, no longer used.
33916 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

33936 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
33937 Insert_Dereference_Action when rewriting an implicit dereference into
33938 an explicit one, this will be taken care of during expansion of the
33939 explicit dereference.
33940 (Expand_N_Slice): Same. Always do the rewriting, even for the case
33941 of non-packed slices, since the dereference action generated by
33942 expansion of the explicit dereference is needed in any case.
33943 (Expand_N_Selected_Component): When rewriting an implicit dereference,
33944 analyze and resolve the rewritten explicit dereference so it is seen
33946 (Insert_Dereference_Action): This procedure is now called only for the
33947 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
33948 dereferences that do not come from source (including explicit
33949 dereferences resulting from rewriting implicit ones), but do not
33950 recursively insert a check for the dereference nodes contained within
33952 (Insert_Dereference_Action): Clarify and correct comment.

34829 checks for bitfield creation are triggered.
34830 (finish_record_type): During last pass over the fields, clear

35171 2004-01-12 Ed Schonberg <schonberg@gnat.com>
35173 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
35174 generated to rename a generic actual, go to the actual itself, the
35175 subtype is not a user-visible entity.
35177 * sem_ch7.adb (Uninstall_Declarations): If an entity in the visible
35178 part is a private subtype, reset the visibility of its full view, if
35179 any, to be consistent.
35182 * sem_ch12.adb (Analyze_Formal_Package): Diagnose properly an attempt
35183 to use a generic package G as a formal package for another generic

35217 * 1ssecsta.ads: Default_Secondary_Stack is not a constant since it may
35218 be modified by the binder generated main program if the -D switch is
35221 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
35222 imported functions (since now we expect this to be done for imported
35225 * 5vtaprop.adb: Add several ??? for sections requiring more comments
35226 Minor reformatting throughout
35228 * 5zinit.adb: Minor reformatting

35234 * sprint.adb: Minor updates to avoid -gnatwa warnings
35236 * s-secsta.ads, s-secsta.adb:
35237 (SS_Get_Max): New function to obtain high water mark for ss stack
35238 Default_Secondary_Stack is not a constant since it may be modified by
35239 the binder generated main program if the -D switch is used.
35241 * switch-b.adb: New -Dnnn switch for binder
35244 Make -gnatg imply all warnings currently in -gnatwa

35275 Acquire new SS indication of secondary stack use from ali files
35277 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
35278 (since now we expect this to be done for imported functions)
35280 * bindgen.adb: Generate call to modify default secondary stack size if
35283 * bindusg.adb: Add line for new -D switch
35285 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
35286 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
35287 Add circuitry for both records and arrays to avoid gigi
35288 processing if the type involved has non-bit-aligned components
35290 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
35291 N_String_Literal node always references an E_String_Literal_Subtype
35292 entity. This may not be true in the future.
35293 (Possible_Bit_Aligned_Component): Move processing of
35294 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
35296 * exp_ch6.adb (Expand_Thread_Body): Pick up
35297 Default_Secondary_Stack_Size as variable so that we get value modified
35298 by possible -Dnnn binder parameter.
35300 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
35301 (Type_May_Have_Bit_Aligned_Components): New function.
35303 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

35336 * rtsfind.adb (Load_Fail): Give full error message in configurable
35337 run-time mode if all_errors mode is set. This was not done in the case
35338 of a file not found, which was an oversight.
35339 Note if secondary stack unit is used by compiler.
35341 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
35342 ineffective elaborate all pragmas on non-visible packages (this
35343 happened when a renamed subprogram was called). Now the elaborate all
35344 always goes on the package containing the renaming rather than the one
35345 containing the renamed subprogram.
35347 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
35348 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

35351 has an Etype that references an E_String_Literal.
35352 (Eval_String_Literal): Avoid assumption that N_String_Literal node
35353 always references an E_String_Literal_Subtype entity. This may not
35354 be true in the future.

35359 * sem_res.adb (Resolve): Specialize msg for function name used in proc
35362 2004-01-05 Ed Falis <falis@gnat.com>

35370 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
35373 * make.adb (Gnatmake): Special process for files to compile/check when
35374 -B is specified. Fail when there are only foreign mains in attribute
35375 Main of the project file and -B is not specified. Do not skip bind/link
35376 steps when -B is specified.
35378 * makeusg.adb: Document new switch -B

35401 -gnatwa warning on static condition.
35403 2004-01-05 Doug Rupp <rupp@gnat.com>

35407 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
35409 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
35410 all attributes, including read-only attribute.
35412 2004-01-05 Pascal Obry <obry@gnat.com>

35415 library naming scheme.
35417 * mlib-prj.adb (Build_Library): Generate different names for the static
35418 or dynamic version of the GNAT runtime. This is needed to support the
35419 new shared library naming scheme.

35421 based on the new naming scheme.
35423 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
35424 scheme for the shared runtime libraries.
35427 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
35429 (install-gnatlib): Do not create symlinks for shared libraries.
35430 (gnatlib-shared-default): Idem.
35431 (gnatlib-shared-dual-win32): New target. Not used for now as the
35432 auto-import feature does not support arrays/records.
35433 (gnatlib-shared-win32): Do not create copy for the shared libraries.
35434 (gnatlib-shared-vms): Fix shared runtime libraries names.
35436 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
35437 dependent runtime shared library name.
35439 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
35441 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
35444 2004-01-05 Ed Schonberg <schonberg@gnat.com>
35446 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
35447 protected objects when allocator has a subtype indication, not a
35448 qualified expression. Note that qualified expressions may have to be
35449 checked when limited aggregates are implemented.
35451 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
35452 pure, emit warning.
35453 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
35454 subprogram is imported, remove warning.
35456 2004-01-05 Geert Bosch <bosch@gnat.com>
35458 * s-poosiz.adb: Update copyright notice.
35459 (Allocate): Use Task_Lock to protect against concurrent access.

35498 * cstand.adb (Create_Standard): Change the way how the declaration of
35499 the Duration type is created (making it the same way as it is for all
35500 the other standard types).

35512 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
35513 are universal and already analyzed, as can occur in constrained
35514 subcomponents that depend on discriminants, when one constraint is a
35517 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
35518 type Any_Fixed is legal as the argument of a conversion, if only one

35599 Minor reformatting throughout
35601 2003-12-11 Ed Schonberg <schonberg@gnat.com>
35603 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
35604 bounds of a loop, create a separate block in order to generate proper
35605 cleanup actions to prevent memory leaks.
35607 * sem_res.adb (Resolve_Call): After a call to
35608 Establish_Transient_Scope, the call may be rewritten and relocated, in

35611 * sem_util.adb: (Wrong_Type): Refine previous fix.
35612 Fixes ACATS regressions.
35615 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
35618 2003-12-08 Jerome Guitton <guitton@act-europe.fr>

35624 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
35627 2003-12-08 Robert Dewar <dewar@gnat.com>
35629 * 7sintman.adb: Minor reformatting
35631 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
35632 standard linker options to get standard libraries linked. We now plan
35633 to provide dummy versions of these libraries to match the appropriate
35634 configurable run-time (e.g. if a library is not needed at all, provide
35635 a dummy empty library).
35637 * targparm.ads: Configurable_Run_Time mode no longer affects linker
35638 options (-L parameters and standard libraries). What we plan to do is
35639 to provide dummy libraries where the libraries are not required.
35641 * gnatbind.adb: Minor comment improvement
35643 2003-12-08 Javier Miranda <miranda@gnat.com>
35645 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
35646 aggregate in the parent. Otherwise constants with limited aggregates
35647 are not supported. Add new formal to pass the component type (Ctype).
35648 It is required to call the corresponding IP subprogram in case of
35649 default initialized components.
35650 (Gen_Assign): In case of default-initialized component, generate a
35651 call to the IP subprogram associated with the component.

36066 Adding a check to see whether the Interrupt_ID we want to unmask is in
36067 the range of Keep_Unmasked (in procedure Interrupt_Self_Process). The
36068 reason is that the index type of the Keep_Unmasked array is not always

39450 2002-02-07 Richard Henderson <rth@redhat.com>
39452 * adaint.c (__gnat_to_gm_time): First arg is int, not time_t.

39475 (title page): Remove date.
39476 (general) Add @./@: where approriate, and two spaces after the
39477 full stop at the end of a sentence. Use @samp markup when
39478 referring concrete lexical entities (keywords, attribute names
39479 etc.), and @syntax for ARM grammar elements. Use @r for English

39492 2001-12-22 Florian Weimer <fw@deneb.enyo.de>
39494 * make.adb (Add_Switch): Make Generic_Position a procedure. The
39495 function approach did not work well because of a side effect (the
39496 function call could reallocate the table which was being indexed
39497 using its result). Fixes ada/4851.

39556 Add 2001 to copyright date
39558 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no

39683 Above changes fix problem with length computation for supernull arrays
39684 where Max (Len, 0) wasn't getting applied due to the Unsigned
39685 conversion used by Compute_Length.

39775 When using a project file, fail if specified executable is relative
39776 path with directory information, and prepend executable, if not
39777 specified as an absolute path, with the exec directory. Make sure
39778 that only one -o switch is transmitted to the linker.
39780 * prj-attr.adb (Initialization_Data): Add project attribute Exec_Dir

39861 there could be a real problem here with an uninitialized reference
39862 to Hbound, but no actual example of failure has been found.
39864 2001-12-17 Laurent Pautet <pautet@gnat.com>
39867 Fix comment of Shutdown_Socket and Close_Socket. These functions
39868 should not fail silently because if they are called twice, this
39869 probably means that there is a race condition in the user program.
39870 Anyway, this behaviour is consistent with the rest of this unit.
39871 When an error occurs, an exception is raised with the error message
39872 as exception message.
39874 2001-12-17 Robert Dewar <dewar@gnat.com>

41206 instead of the previous simple checksum algorithm.
41207 (Time_Stamp_Mismatch): use CRC_Match for comparison.
41208 (Set_Source_Table): idem.
41211 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
41212 instead of simple checksum.
41213 (CRC_Match): new function.
41214 (CRC_Error): new constant.
41216 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
41217 a CRC now and not a simple checksum. A CRC uses lower-case hex
41218 letters, fixes ambiguity in parsing.
41220 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
41221 is what this variable will store.
41223 * bcheck.adb: Change reference to chechsum in comments by CRC.
41224 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
41225 rename All_Checksum_Match to All_CRC_Match. Change due to API
41226 renaming since now GNAT does not use a simple checksum but a
41227 CRC using GNAT.CRC32.
41229 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
41230 now and not anymore a simple checksum.

41269 * types.adb (Hex): Use lowercase for the letter part.
41271 * types.ads (Get_Hex_String): Returns the hexadecimal representation
41272 for a word. This is currently used only for CRC. In previous version,
41273 the checksum was using a representation with all letter being
41274 upper-case. With the new implementation (using CRC) we do not remove
41275 the 32th bit of the CRC, so we can have an upper-case starting letter
41276 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
41277 It is ambigous since the CRC was optional and could be followed by
41278 options like EB, EE. So now this routines uses lower-case letter for
41279 the hexadecimal representation. Strange enough only lower case letters
41280 where checked in Scan_ALI (even if this was not a possible case).
41282 * gnatvsn.ads (Library_Version): changed to 3.15a.
41284 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
41287 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
