1273 subprogram body that acts as its own spec may not have a non-private
1274 WITH clause on a private sibling.
1275 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
1276 child unit is a renaming, create an implicit with_clause on that
1277 parent, and not on the unit it renames, to prevent visibility errors

1342 formal of a generic subprogram. find candidate interpretations by
1343 scanning the list of generic formal declarations.:
1344 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
1345 type from a limited_with_clause, and the full view is available, use it

1376 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
1377 requeue statement is dispatching. Do not emit an error when the name is

1379 perform subtype conformance between the formals of the current entry
1380 and those of the target interface primitive.
1381 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
1382 Timed_Entry_Call): Analyze the triggering statement as the first step of
1383 the processing. If this is a dispatching select, postpone the analysis
1384 of all select statements until the Expander transforms the select. This
1385 approach avoids generating duplicate identifiers after the Expander has
1386 replicated some of the select statements. In case the Expander is
1387 disabled, perform regular analysis.
1388 (Check_Triggering_Statement): New routine.
1389 (Analyze_Requeue): Exclude any interpretations that are not entries when
1390 checking overloaded names in a requeue. Also test type conformance for
1391 matching interpretations rather than requiring subtype conformance at

1396 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
1397 inherited operation is a defaulted tag-indeterminate call, and there is
1398 a statically tagged actual, use the static tag as a controlling actual
1399 for the defaulted actual.
1401 2007-12-13 Geert Bosch <bosch@adacore.com>
1403 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

2086 (Process_Declarative_Items): Ditto
2087 (Process_Project_Tree_Phase_1): Set Success to False in case an error is
2090 * prj-util.adb (Value_Of (In_Array)): When Force_Lower_Case_Index is
2091 True, compare both indexes in lower case.

2097 2007-10-15 Gary Dismukes <dismukes@adacore.com>
2099 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
2100 association for an access component, add an association with null as
2101 the expression. Remove testing for array subtypes and the setting in
2102 that case of Ctyp to the array component type, which prevented proper
2103 inclusion of an association for null-initialized arrays. Collapse
2104 condition that tests for array subtypes into just a test of
2105 Is_Partially_Initialized_Type (which already covers arrays anyway).
2107 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
2109 * sem_ch12.adb: Minor code reformatting.
2110 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to

2122 * sem_ch4.adb: Minor code and comment reformatting.
2123 (Analyze_Allocator): When the designated type of an unconstrained
2124 allocator is a record with unknown discriminants or an array with
2125 unknown range bounds, emit a detailed error message depending on the
2126 compilation mode and whether the designated type is limited.

2249 2007-09-27 Eric Botcazou <ebotcazou@adacore.com>
2251 Mapped location support
2252 * back_end.adb (Call_Back_End): Pass information about source
2253 files instead of units to gigi.
2254 * gigi.h (struct File_Info_Type): New.
2255 (gigi): Rename and change type of number_units parameter, change
2256 type of file_info_ptr parameter.
2257 * trans.c (number_files): New global variable.
2258 (gigi): Rename and change type of number_units parameter, change
2259 type of file_info_ptr parameter.
2260 If mapped location support is enabled, create the isomorphic mapping
2261 between source files and line maps.
2262 (Sloc_to_locus): If mapped location support is enabled, translate
2263 source location into mapped location.
2264 (annotate_with_node): Rename into set_expr_location_from_node.

2290 * a-calend-vms.adb, a-calend.adb:
2291 Add a section on leap seconds control along with two entities used to
2292 enable and disable leap seconds support. The array Leap_Second_Times is
2293 now constant and contains hard time values pre-generated. Remove
2294 all elaboration code used to populate the table of leap seconds.
2297 Add entity Leap_Seconds_Support to the list of global run-time variables
2298 along with a comment on its usage and values.
2299 (Gen_Adainit_Ada): Add code to generate the declaration and import of
2300 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
2301 or one (enabled) depending on the presence of binder switch "-y".
2302 (Gen_Adainit_C): Add code to generate the declaration of external int
2303 __gl_leap_seconds_support. Set is value to zero (disabled) or one

2314 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
2316 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
2318 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
2319 function which can be called by the debugger to interrupt the tasks of
2320 an Ada application asynchronously, as needed on VxWorks.
2321 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
2323 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,

2340 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
2342 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
2345 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
2347 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
2350 * sem_dist.ads: Minor comment fix

2354 2007-09-26 Javier Miranda <miranda@adacore.com>
2355 Eric Botcazou <ebotcazou@adacore.com>
2358 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
2359 indirection added to the HT_Link component of the TSD. This is required
2360 to statically allocate the TSD.
2363 Minor reordering of the declarations in the private part. Required to
2364 add a level of indirection to the contents of the TSD component HT_Link.
2365 This is required to statically allocate the TSD.
2367 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
2368 Is_Statically_Allocated set from constant objects.
2369 Do not make exported constants created by the compiler volatile.
2370 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
2373 * trans.c (Identifier_to_gnu): For constants, unshare initializers
2374 before returning them.
2376 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
2377 public part of the package.
2378 (Make_DT): Move HT_Link component out of the TSD record. For this
2379 purpose Make_DT now declares a separate object that stores the
2380 HT_Link value, and initializes the TSD component with the address
2381 of this new object. The addition of this level of indirection is
2382 required to statically allocate the TSD because the TSD cannot
2383 have variable components.
2384 (Expand_Interface_Conversion): Improve the expanded code.
2385 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
2387 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
2388 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
2389 if we are building static dispatch tables then we must not generate
2390 extra code to register the primitive because the dispatch table will
2391 be built at the end of the library package; otherwise we notify that
2392 we cannot build the static dispatch table.
2394 2007-09-26 Robert Dewar <dewar@adacore.com>
2396 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

2411 for thunks associated with interface types.
2413 * einfo.ads: Improve documentatation of Is_Internal
2414 (Is_Thunk): New attribute applicable to subprograms. True for thunks
2415 associated with interface types.
2416 Extensive comment fixes regarding flags that appear in all entities. The
2417 documentation is now consistent for all such flags (there were a number
2418 of errors in the documentation in this regard).
2420 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
2422 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
2423 of these procedures are passed a function call that already has
2424 build-in-place actuals (testing new flag
2425 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
2426 the case where processing continues.
2427 (Expand_Call): If the call is generated from a thunk body then we
2428 propagate the extra actuals associated with the accessibility
2429 level of the access type actuals.
2431 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
2432 of each extra formal of a protected operation to reference the
2433 corresponding extra formal of the subprogram denoted by the
2434 operation's Protected_Body_Subprogram.
2436 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
2437 N_Function_Call nodes.
2439 2007-09-26 Robert Dewar <dewar@adacore.com>
2441 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
2443 * debug.adb: Add d.s flag.
2445 2007-09-26 Gary Dismukes <dismukes@adacore.com>
2447 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
2448 debug variable so that it won't be initialized when pragma
2449 Initialize_Scalars is in effect.
2451 2007-09-26 Gary Dismukes <dismukes@adacore.com>
2453 * freeze.adb (Freeze_Entity): Remove check for preelaborable
2454 initialization of a full view. This is moved to
2455 Analyze_Package_Specification.
2457 * sem_ch7.adb (Analyze_Package_Specification): Add check for
2458 preelaborable initialization of a full view in entity loop.
2459 (Uninstall_Declarations): If entity is a use-visible compilation unit,
2460 its child units are use-visible only if they are visible child units.
2462 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
2463 whether an expression can be used within a type declaration that
2464 requires preelaborable init.
2465 (Check_Components): Replace inline code that does partial checking for
2466 preelaborable default expressions with call to
2467 Is_Preelaborable_Expression.
2468 (Has_Preelaborable_Initialization): In the case of a generic actual
2469 subtype, (that is, Is_Generic_Actual is True), return the result of
2470 applying Has_Preelaborable_Initialization to the generic actual's base
2473 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
2475 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
2476 call to Jan_1_Day _Of_Week to optimize its performance.
2477 (Is_Leap): Move the routine to the scope of Week_In_Year.
2478 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
2479 weekday on which January 1 falls of Year - 1 and Year + 1. This function
2480 avoids calling Time_Of and Split, thus making it more efficent.
2481 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
2483 * g-calend.ads (Week_In_Year): Change comment to reflect new
2486 2007-09-26 Emmanuel Briot <briot@adacore.com>
2488 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
2489 Command_Line): New types
2490 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
2491 support for defining how switches can be grouped on a command line (as
2492 is the case for -gnatw... for GNAT), and how simple switches can be
2493 used as aliases for more complex switches (-gnatwa is same as
2495 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
2496 (Start, Current_*): New subprograms
2497 Added support for parsing an array of strings in addition to the real
2499 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
2500 be moved from the body to the private part of the spec.
2501 (*): All subprograms now have an extra parameter with default value to
2502 specify which parser should be used. For backward compatibility, it
2503 defaults to parsing the command line of the application. They were also
2504 modified to properly handle cases where each of the argument does not
2505 start at index 1 (which is always true for Ada.Command_Line, but not
2506 when processing any Argument_List).
2507 (Free): New subprogram
2508 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
2509 Argument): New subprograms
2510 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
2511 special characters like ':', '=',... are now handled in a single place,
2512 which makes the code more extensible eventually.
2513 (Getopt, Full_Switch): When the switch was returned as part of the
2514 special character '*', make sure it is prepended by the switch character
2515 ('-' in general), so that the application knows whether "foo" or "-foo"
2516 was specified on the command line.
2518 2007-09-26 Florian Villoing <villoing@adacore.com>
2520 * g-dirope.adb (Remove_Dir): In case we are removing directories
2521 recursively, make sure that if an exception is raised during the
2522 processing, the current working directory is reset to its initial
2523 value before propagating the exception.
2525 2007-09-26 Vincent Celier <celier@adacore.com>
2527 * gnatbind.adb: If there are several ALI files specified and there is
2528 a main program to bind, the first ALI is expected to contain the main
2529 subprogram and the names of the binder generated files will be derived
2530 from the first ALI file name.
2531 (Gnatbind): Fix insertion character in invocation of Error_Msg
2533 2007-09-26 Vincent Celier <celier@adacore.com>
2535 * gnatcmd.adb (Check_Files): Do not include sources that have been
2536 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
2538 2007-09-26 Ed Schonberg <schonberg@adacore.com>
2540 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
2541 information about each of its index types, following the type
2542 reference for its component type.
2544 2007-09-26 Vincent Celier <celier@adacore.com>
2546 * make.adb: (Kill): New procedure (__gnat_kill imported)
2547 (Running_Compile, Outstanding_Compiles): Global variables that
2548 were previously local to procedure Compile_Sources.
2549 (Sigint_Intercepted): Send signal SIGINT to all outstanding
2550 compilation processes.
2552 (Gnatmake): If project files are used, create the mapping of all the
2553 sources, so that the correct paths will be found.
2555 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
2557 2007-09-26 Vincent Celier <celier@adacore.com>
2559 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
2561 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
2562 Replace components Compiler_Min_Options and Binder_Min_Options with
2563 Compiler_Required_Switches and Binder_Required_Switches in record
2565 Remove components Default_Language and Config in Project_Tree_Data,
2568 * prj-attr.adb: New attributes Required_Switches (<language>) in
2569 packages Compiler and Binder.
2571 * prj-nmsc.adb: Major rewrite of the processing of configuration
2572 attributes for gprbuild. No impact on GNAT tools.
2574 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
2575 process configuration attributes: this is done in Prj.Nmsc.Check.
2576 (Recursive_Process): Make a full copy of packages inherited from project
2577 being extended, instead of a shallow copy.
2578 (Process_Project_Tree_Phase_1): New procedure
2579 (Process_Project_Tree_Phase_1): New procedure
2580 (Process): Implementation now uses the two new procedures
2582 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
2583 from the project config, not the tree config that no longer exists.
2585 2007-09-26 Vincent Celier <celier@adacore.com>

2598 message to cite use of <> in aggregate component associations rather
2599 than wrongly indicating use of limited aggregates.
2601 2007-09-26 Robert Dewar <dewar@adacore.com>
2603 * sem_attr.adb (Analyze_Access_Attribute): Fix missing set of
2606 2007-09-26 Ed Schonberg <schonberg@adacore.com>
2608 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct

2914 potentially be called.
2915 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
2916 body for 'Output when the type is abstract (only the creation of the
2917 body for 'Input is excluded when the type is abstract).

2919 statement, so that False will be returned for TTS_Stream_Input if the
2920 associated tagged type is an abstract extension. Add comments for

2923 variable, insert init proc call only after the shared variable
2924 procedures have been processed, because the IP call needs to undergo

2926 procedures to be available (and elaborated).

2942 to remove other spurious ambiguities on arithmetic operations involving
2943 literals and addresses, on systems where Address is a visible integer
2944 type, when the operator is called in functional notation.
2945 (Try_Primitive_Operation): Within an instance, a call in prefixed form
2946 is legal when the types match, even if the operation is currently

3071 (Write_Entity_Flags): Write the status of flag Is_Raised.
3072 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
3073 spurious ambiguities when integer literals appear in the context of an
3074 address type that is a visible integer type.
3076 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
3077 exceptions never being raised.

3094 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
3095 library-level package renaming, pass the declaration associated with
3096 the renaming's special debug variable to Qualify_Entity_Names to ensure
3097 that its encoded name is properly qualified.
3099 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
3100 occurring in the list of entities to qualify, and do not attempt to
3101 traverse an entity list in that case. Variables associated with
3102 ` library-level package renamings can now occur in the table.
3104 * exp_dbug.ads: Revise documentation of the encoding for renaming
3107 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

3121 to include loop parameters.
3122 (Valid_Conversion): Avoid generation of spurious error message.

3126 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
3127 concatenations of string literals into a single literal, in order to
3128 avoid very deep recursion in the front end, which was causing stack
3131 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
3132 string, and the right operand is a string literal (the case of "" &
3133 "..."), optimize by avoiding copying the right operand -- just use the
3134 value of the right operand directly.
3136 * stringt.adb (Store_String_Chars): Optimize by growing the
3137 String_Chars table all at once, rather than appending characters one by
3139 (Write_String_Table_Entry): If the string to be printed is very long,
3140 just print the first few characters, followed by the length. Otherwise,
3141 doing "pn(n)" in the debugger can take an extremely long time.
3143 * sem_prag.adb (Process_Interface_Name): Replace loop doing
3144 Store_String_Char with Store_String_Chars.
3146 2007-08-31 Vincent Celier <celier@adacore.com>

3163 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
3164 flag, for effiency. It is called when analyzing arithmetic operators
3165 and also for actuals in calls that are universal_integers. The flag is
3166 set for the predefined type address, and for any type or subtype
3169 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
3170 Universal_Integer, when the formal is a descendent of address and the
3171 call appears in user code.

3238 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
3239 associated with Standard_Debug_Renaming_Type, to be used as the type of
3240 the special variables whose names provide debugger encodings for
3241 renaming declarations.
3243 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
3244 (Set_Debug_Renaming_Link): Change to set Node25.

3250 * exp_dbug.adb: Add with and use of Tbuild.
3251 (Debug_Renaming_Declaration): Replace creation of an enumeration type
3252 and literal with creation of a variable of type
3253 Standard_Debug_Renaming_Type whose name encodes both the renamed object
3254 and the entity of the renaming declaration.
3255 (Qualify_Entity_Name): Add the delayed qualification of the entity name
3256 part of the name of a variable that has a Debug_Renaming_Link.

3263 Ed Schonberg <schonberg@adacore.com>
3264 Javier Miranda <miranda@adacore.com>
3266 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
3267 ancestor part given by an aggregate to test for an unchecked conversion,
3268 since this can occur in some cases when the ancestor part is a function
3269 call, and we don't want to fall into the recursive call to this
3270 procedure in that case.
3272 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
3273 stream attributes on limited types to account for user-specified
3274 attributes as well as whether Input (resp. Output) becomes available
3275 due to Read (resp. Write) being available for the type. Change Boolean
3276 variable to the more accurate name
3277 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
3278 double-"not" predicate at beginning of return statement to more
3279 understandable form.
3281 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
3282 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
3283 in a block statement and use that as the first statement of the
3284 expanded return rather than incorrectly using the handled sequence as
3285 the first statement.
3287 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
3288 operation, generate an explicit freeze node for it rather than
3289 generating extra formals, to ensure that gigi has the proper order of
3290 elaboration for anonymous subtypes in the signature of the subprograms.
3291 (Build_In_Place_Formal): Move assertion to beginning of loop.
3292 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
3293 applied to a function call (occurs for some cases of 'Input).
3294 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
3295 applied to a function call (occurs for some cases of 'Input).
3297 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
3298 2005, generate an extended return statement enclosing the result object
3301 * freeze.adb (Freeze_Record_Type): Extend the current management of
3302 components that are access type with an allocator as default value: add
3303 missing support to the use of qualified expressions of the
3304 allocator (which also cause freezing of the designated type!)
3305 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
3306 dispatching operation, since extra formals may be needed by calls to
3307 build-in-place functions (such as stream 'Input).
3309 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
3310 formals for 'Constrained and accessibility level in the case of a
3311 predefined dispatching operation.
3313 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
3314 point, no need to find the parent node.
3316 2007-08-16 Javier Miranda <miranda@adacore.com>
3318 * exp_attr.adb (Attribute_Priority): Add missing support for entries
3321 2007-08-16 Javier Miranda <miranda@adacore.com>
3323 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
3324 is not really required and can introduce regression with the debugger.
3325 The original problem is fixed with the patch written for checks.adb.
3327 2007-08-16 Thomas Quinot <quinot@adacore.com>
3329 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
3330 Range_Check on Allocated_Table.

3334 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
3335 Including_Non_Switch set to False.
3336 (Gnatmake): For the compiler, call Test_If_Relative_Path with
3337 Including_Non_Switch set to False.
3339 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
3340 parameter Including_Non_Switch, defaulted to True. When
3341 Including_Non_Switch is False, options that are not switches and
3342 appear as relative path are not converted to absolute paths.

3354 currently inspected is a selected component, retrieve the entity of
3356 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
3357 from the immediate ancestor of Main_Unit_Entity.
3358 (Install_Limited_Withed_Unit): Do not install the limited view of
3359 package P if P is reachable through an ancestor chain from package C
3360 and C also has a with clause for P in its body.
3361 (Has_Limited_With_Clause): New routine.
3362 (Has_With_Clause): New routine.
3364 2007-08-16 Ed Schonberg <schonberg@adacore.com>
3366 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
3367 generic for an enclosing instance is a global reference, even though
3368 its scope is the enclosing instance.
3370 2007-08-16 Gary Dismukes <dismukes@adacore.com>
3371 Javier Miranda <miranda@adacore.com>
3373 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
3374 initialize a limited object.
3375 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
3377 Make sure Has_Complex_Representation is inherited by derived type.

3384 2007-08-16 Ed Schonberg <schonberg@adacore.com>
3386 * sem_disp.adb (Check_Dispatching_Operation): If the operation
3387 implements an operation inherited from a progenitor interface, verify
3388 that they are subtype-conformant.

3391 Bob Duff <duff@adacore.com>
3392 Nicolas Setton <setton@adacore.com>
3394 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
3395 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
3396 the statement which is being resolved comes from a predefined library
3397 unit, all non-predefined library interpretations are skipped.
3398 (Resolve_Op_Concat): If string concatenation was folded in the parser,
3399 but the "&" is user defined, give an error, because the folding would
3402 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
3403 the parser has folded a long sequence of concatenations of string
3406 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
3407 and "JMP_BUF" variables as artificial.
3408 (N_String_Literal): Do not use alloca for very long string literals. Use
3409 xmalloc/free instead. Otherwise the stack might overflow.

3454 Ed Schonberg <schonberg@adacore.com>
3456 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
3457 Suppress unmodified in-out parameter warning in some cases
3458 This patch is a also fairly significant change to the way suppressible
3461 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
3462 needed for access to concurrent record types generated by the expander.
3463 (Generate_Range_Check): When generating a temporary to capture the
3464 value of a conversion that requires a range check, set the type of the
3465 temporary before rewriting the node, so that the type is always
3466 properly placed for back-end use.
3467 (Apply_Float_Conversion_Check): Handle case where the conversion is
3469 (Get_Discriminal): Code reformatting. Climb the scope stack looking
3470 for a protected type in order to examine its discriminants.

3482 (Get_Allocator_Final_List): For the case of an anonymous access type
3483 that has a specified Associated_Final_Chain, do not go up to the
3485 (Expand_N_Type_Conversion): Test for the case of renamings of access
3486 parameters when deciding whether to apply a run-time accessibility
3488 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
3489 aggregate code before allocator, and ahead of declaration for
3490 temporary, to prevent access before elaboration when the allocator is
3491 an actual for an access parameter.
3492 (Expand_N_Type_Conversion): On an access type conversion involving an
3493 access parameter, do not apply an accessibility check when the
3494 operand's original node was an attribute other than 'Access. We now
3495 create access conversions for the expansion of 'Unchecked_Access and
3496 'Unrestricted_Access in certain cases and clearly accessibility should
3497 not be checked for those.
3499 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
3500 includes a type conversion of a packed component that has been expanded,
3501 recover the original expression for the object, and use this expression
3502 in the post-call assignment statement, so that the assignment is made
3503 to the object and not to a back-end temporary.
3504 (Freeze_Subprogram): In case of primitives of tagged types not defined
3505 at the library level force generation of code to register the primitive
3506 in the dispatch table. In addition some code reorganization has been
3507 done to leave the implementation clear.
3508 (Expand_Call): When expanding an inherited implicit conversion,
3509 preserve the type of the inherited function after the intrinsic
3510 operation has been expanded.
3512 * exp_ch2.ads, exp_ch2.adb
3513 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
3514 of an entry formal appearing in an assignment statement does not assign
3516 (Expand_Current_Value): Instead of calling a routine to determine
3517 whether the prefix of an attribute reference should be optimized or
3518 not, prevent the optimization of such prefixes all together.
3520 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
3521 component whose prefix is known to be of an access type is an implicit
3522 dereference and does not assign to the prefix.

3534 node, to prevent errors when complex expression is copied.
3535 Fix mishandling of multiple levels of parens

3594 generation of a freezing node to ensure proper management of null
3595 excluding access types in the backend.
3596 (Create_Extra_Formals): Test base type of the formal when checking for
3597 the need to add an extra accessibility-level formal. Pass the entity E
3598 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
3599 originally being done in a couple of cases), to ensure that the
3600 Extra_Formals list gets set on the entity E when the first entity is
3602 (Conforming_Types): Add missing calls to Base_Type to the code that
3603 handles anonymous access types. This is required to handle the
3604 general case because Process_Formals builds internal subtype entities
3605 to handle null-excluding access types.
3606 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
3607 functions that need it, even when not marked Requires_Overriding.
3608 Improve warnings for in out parameters
3609 (Analyze_Function_Return): Warn for disallowed null return
3610 Warn on return from procedure with unset out parameter
3611 Ensure consistent use of # in error messages
3612 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
3613 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
3614 the implicit conversion of the expression done for anonymous access
3615 types. This is required to generate the code of the null excluding
3616 check (if required).
3618 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
3619 A formal parameter is never publicly referenceable outside of its body.

3621 statement, use the same warning circuitry as for subprogram formal
3623 (Warn_On_Unreferenced_Entity): New subprogram, taken from
3624 Output_Unreferenced_Messages, containing the part of that routine that
3625 is now reused for entry formals as described above.
3626 (Goto_Spec_Entity): New function
3627 (Check_References): Do not give IN OUT warning for dispatching operation
3628 Improve warnings for in out parameters
3629 (Test_Ref): Check that the entity is not undefinite before calling
3630 Scope_Within, in order to avoid infinite loops.
3631 Warn on return from procedure with unset out parameter
3632 Improved warnings for unused variables

3635 Javier Miranda <miranda@adacore.com>
3636 Gary Dismukes <dismukes@adacore.com>
3638 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
3639 (Expand_N_Attribute_Reference): Further unify the handling of the
3640 three forms of access attributes, using common code now for all three
3641 cases. Add a test for the case of applying an access attribute to
3642 an explicit dereference when the context is an access-to-interface
3643 type. In that case we need to apply the conversion to the prefix
3644 of the explicit dereference rather than the prefix of the attribute.
3645 (Attribute_Version, UET_Address): Set entity as internal to ensure
3646 proper dg output of implicit importation.
3647 (Expand_Access_To_Type): Removed.
3648 (Expand_N_Attribute_Reference): Merge the code from the three cases
3649 of access attributes, since the processing is largely identical for
3650 these cases. The substantive fix here is to process the case of a
3651 type name prefix (current instance case) before handling the case
3652 of interface prefixes.

3656 Javier Miranda <miranda@adacore.com>
3657 Robert Dewar <dewar@adacore.com>
3659 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
3660 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
3661 type that is an anonymous access to controlled object, establish
3662 an associated finalization chain to avoid corrupting the global
3663 finalization list when a dynamically allocated object designated
3664 by such a component is deallocated.
3665 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
3666 functions that need it, even when not marked Requires_Overriding.
3667 (Initialize_Tag): Replace call to has_discriminants by call to
3668 Is_Variable_Size_Record in the circuitry that handles the
3669 initialization of secondary tags.

3671 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
3672 Suppress_Initialization pragma for a derived type.
3673 (Is_Variable_Size_Record): New subprogram.
3674 (Build_Offset_To_Top_Functions): New implementation that simplifies the
3675 initial version of this routine and also fixes problems causing
3676 incomplete initialization of the table of interfaces.
3677 (Build_Init_Procedure): Improve the generation of code to initialize the
3678 the tag components of secondary dispatch tables.
3679 (Init_Secondary_Tags): New implementation that simplifies the previous
3680 version of this routine.

3684 diagnose attemps to freeze a subprogram when some untagged type of its
3685 profile is a private type whose full view has not been analyzed yet.
3686 (Freeze_Array_Type): Generate init proc for packed array if either
3687 Initialize or Normalize_Scalars is set.
3688 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
3689 constructing the new profile, copy the null_exclusion indicator for each
3690 parameter, to ensure full conformance of the new body with the spec.
3692 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
3693 Create wrappers for constructor functions that need it, even when not
3694 marked Requires_Overriding.

3707 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
3708 (Write_Overloads): Output the abstract operator if present.
3709 (Add_Entry): Before inserting a new entry into the interpretation table
3710 for a node, determine whether the entry will be disabled by an abstract
3712 (Binary_Op_Interp_May_Be_Hidden): New routine.
3713 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
3715 (Function_Interp_May_Be_Hidden): New routine.
3716 (Has_Compatible_Type): Do not consider interpretations hidden by

3734 output of implicit importation and exportation.
3735 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
3736 first formal of the thunk is always associated with the controlling
3737 type. In addition perform the following code cleanup: remove formal
3738 Thunk_Alias which is no longer required, cleanup evaluation of the
3739 the controlling type, and update the documentation.
3740 Replace occurrence of Default_Prim_Op_Count by
3741 Max_Predef_Prims. Addition of compile-time check to verify
3742 that the value of Max_Predef_Prims is correct.
3743 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
3744 (Make_DT): Add parameter to indicate when type has been frozen by an
3745 object declaration, for diagnostic purposes.

3747 construction of statically allocated dispatch tables.
3748 (Make_DT): In case of library-level tagged types export the declaration
3749 of the primary tag. Remove generation of tags (now done by Make_Tags).
3750 Additional modifications to handle non-static generation of dispatch
3751 tables. Take care of building tables for asynchronous interface types
3752 (Make_Tags): New subprogram that generates the entities associated with
3753 the primary and secondary tags of Typ and fills the contents of Access_
3754 Disp_Table. In case of library-level tagged types imports the forward
3755 declaration of the primary tag that will be declared later by Make_DT.
3756 (Expand_Interface_Conversion): In case of access types to interfaces
3757 replace an itype declaration by an explicit type declaration to avoid
3758 problems associated with the scope of such itype in transient blocks.
3760 2007-08-14 Robert Dewar <dewar@adacore.com>
3761 Ed Schonberg <schonberg@adacore.com>
3762 Javier Miranda <miranda@adacore.com>
3764 * exp_util.ads, exp_util.adb:
3765 This patch replaces a number of occurrences of explicit tests for N_Null
3766 with calls to Known_Null. This improves tracking of null values, since
3767 Known_Null also catches null constants, and variables currently known to
3768 be null, so we get better tracking.
3769 (Ensure_Defined): create an itype reference only in the scope of the
3771 (Side_Effect_Free): A selected component of an access type that
3772 denotes a component with a rep clause must be treated as not
3773 side-effect free, because if it is part of a linked structure its
3774 value may be affected by a renaming.
3775 (Expand_Subtype_From_Expr): For limited objects initialized with build
3776 in place function calls, do nothing; otherwise we prematurely introduce
3777 an N_Reference node in the expression initializing the object, which
3778 breaks the circuitry that detects and adds the additional arguments to
3779 the called function. Bug found working in the new patch for statically
3780 allocated dispatch tables.
3781 (Is_Library_Level_Tagged_Type): New subprogram.
3782 (Remove_Side_Effects): If the expression of an elementary type is an
3783 operator treat as a function call.
3784 (Make_Literal_Range): If the index type of the array is not integer, use
3785 attributes properly to compute the constraint on the resulting aggregate
3788 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
3789 class-wide type whose base type is an incomplete private type, leave
3790 class-wide type unfrozen so that freeze nodes can be generated
3791 properly at a later point.
3792 (Freeze_Entity, array case): Handle case of pragma Pack and component
3793 size attributre clause for same array.

3853 source dirs are not known.
3854 (Check_Ada_Name): Allow all identifiers that are not reserved words
3856 Major update of the Project Manager and of the project aware tools,
3857 including gprmake, so that the same sources in the GNAT repository
3858 can be used by gprbuild.

4471 type, the candidate operations are found in the scope of declaration of
4472 the type, because the type has no primitive subprograms.
4473 (Analyze_Selected_Component): If prefix is class-wide, and root type is
4474 a private extension, only examine visible components before trying to
4475 analyze as a prefixed call.

5686 (Get_E_Length): Protect against bomb in case scope is standard
5687 (Selected_Range_Checks): If the node to be checked is a conversion to

5690 Improve NOT NULL error messages
5691 (Apply_Constraint_Check): If the context is a null-excluding access

5707 Eric Botcazou <ebotcazou@adacore.com>
5708 Arnaud Charlet <charlet@adacore.com>
5710 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
5711 applicable to types that have the With_Type flag set. Returns the
5712 non-limited view of the type, if available, otherwise the type itself.
5713 For class-wide types, there is no direct link in the tree, so we have
5714 to retrieve the class-wide type of the non-limited view of the Etype.
5715 New attributes Static_Initialization and Static_Elaboration_Desired.
5716 Remove the pragma Thread_Body, and the associated flag
5717 Is_Thread_Body in entities, and all related code.

5727 components of records. Set to point to the entity of the corresponding
5729 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
5730 (Original_Access_Type): Remove, not needed.
5731 (Root_Type): Handle properly subtypes of class-wide-types.
5734 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
5735 class-wide types visible through limited-with clauses.
5736 (Try_Primitive_Operation): When examining all primitive operations of a
5737 tagged type, do not consider subprograms labeled as hidden unless they
5738 belong to a private generic type with a tagged parent.
5739 (Try_Object_Operation): Extensive rewriting, to handle properly various
5740 overloading cases, when several ancestors may have class-wide operations
5741 that are possible candidates, and when the overloaded functions return
5742 array types and have defaulted parameters so that the call may be
5743 interpreted as an indexing.
5744 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
5745 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
5746 successive actuals before analyzing the call itself.
5747 (Try_Primitive_Operation): A primitive operation is compatible with the
5748 prefix if the prefix has a synchronized type and the type of the formal
5749 is its corresponding record, as can be the case when the primitive
5750 operation is declared outside of the body of the type.
5751 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
5752 perform homonym traversal, looking for class-wide operation matches
5753 (formerly done in statements of Try_Class_Wide_Operation). Matches on
5754 access parameters are now restricted to anonymous access types.
5755 (Mark_Allocator): An allocator with a discriminant association parent is
5757 (Try_One_Prefix_Interpretation): If the type of the object is
5758 incomplete, as can be happen when it is a limited view obtained through
5759 a limited_with_clause, the selected component is not part of a prefixed
5761 (Complete_Object_Operation): Diagnose properly an object that is not
5762 aliased when the corresponding controlling formal is an access
5764 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
5765 ambiguous calls in prefixed notation, where two primitives differ only
5766 in that the controlling argument of one is an access parameter.
5768 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
5769 whether a function that returns an unconstrained type can be inlined.
5770 (Process_Formals): Diagnose properly the illegal use of an incomplete
5771 type in the profile of an access_to_subprogram declaration.
5772 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
5773 operations are attached to the corresponding record.
5774 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
5775 When processing a primitive of a concurrent type which implements an
5776 interface change the type of all controlling formals to that of the
5777 corresponding record type.
5778 (Check_Synchronized_Overriding): Relax the conditional logic when trying
5779 to determine the tagged type to which a primitive belongs.
5780 (Check_Conventions): Capture condition to ignore a primitive operation
5781 (which is shared between the loop in Check_Conventions and the one in
5782 Check_Convention) in a new local function Skip_Check.
5783 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
5784 confusion with Check_Conventions' own Prim_Op local variable.
5785 (Create_Extra_Formals): Test for a tagged result type rather than a
5786 controlling result when determining whether to add a BIP_Alloc_Form
5787 formal and a BIP_Final_List formal to the function.
5788 (Check_Conformance); For parameters that are anonymous access types,
5789 subtype conformance requires that the not null and the constant
5790 indicators must match
5791 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
5792 to retrieve the appropriate type when processing a concurrent type
5793 declared within a generic. Minor comment reformatting. Change invocation
5794 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
5796 (Analyze_Subprogram_Body): If the return type of a function is an
5797 anonymous access to the limited view of a class-wide type, and the
5798 non-limited view of the type is available, update the type of the
5799 function so that code can be generated.
5800 (Process_Formals): In case of access-subtype itype whose designated
5801 type is also an itype (situation that happens now with access to
5802 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
5803 attribute to avoid backend problems.
5804 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
5805 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
5806 anonymous types' designated types are same before testing
5807 Subtypes_Statically_Match.
5808 (Create_Extra_Formals): Test for a named access parameter that is a
5809 controlling formal as an additional condition for adding an
5810 accessibility level formal. This can occur in the subp type created for
5811 dispatching calls in Expand_Dispatching_Call, and allows calling
5812 Create_Extra_Formals from that procedure rather than special-casing the
5813 extra formals there.
5814 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
5815 when the function has a controlling result.
5816 (Check_Returns): Add much more knowledge of the optimization of local
5817 raise statements to gotos, to retain proper warnings in this case.
5818 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
5819 nodes when looking for last statement.
5821 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
5822 class-wide types visible through limited with clauses.
5823 (Add_One_Interp): If the operands are anonymous access types, the
5824 predefined operator on universal_access is immediately visibles
5825 (Find_Unique_Type): Handle anonymous access to subprogram types just as
5826 other anonymous access types.
5827 (Disambiguate): Take into account CIL convention.
5828 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
5830 2007-06-06 Robert Dewar <dewar@adacore.com>
5832 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
5833 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
5834 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
5835 Fix lower bound of tables.
5838 * nlists.adb: Ditto.
5839 (Prev_Node, Next_Node): Change index type to Int so that it properly
5840 covers the range First_Node_Id - 1 up.
5842 2007-06-06 Javier Miranda <miranda@adacore.com>
5843 Ed Schonberg <schonberg@adacore.com>
5844 Bob Duff <duff@adacore.com>
5845 Hristian Kirtchev <kirtchev@adacore.com>
5847 * exp_aggr.ads, exp_aggr.adb:
5848 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
5849 in extension aggregates.
5850 (Flatten): Other conditions being met, an aggregate is static if the
5851 low bound given by component associations is different from the low
5852 bound of the base index type.
5853 (Packed_Array_Aggregate_Handled): If the component type is itself a
5854 packed array or record, the front-end must expand into assignments.
5855 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
5856 Init_Pr, instead of Ancestor_Is_Expression.
5857 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
5858 coextension chain root, either generate a list controller or use the
5859 already existing one.
5860 (Static_Array_Aggregate): New procedure to construct a positional
5861 aggregate that can be handled by the backend, when all bounds and
5862 components are compile-time known constants.
5863 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
5864 types covering interface types into assignments.
5865 (Replace_Type): move to Build_Record_Aggr_Code.
5866 (Expand_Record_Aggr_Code): if the target of the aggregate is an
5867 interface type, convert to the definite type of the aggregate itself,
5868 so that needed components are visible.
5869 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
5870 components and the context is an extended return statement do not
5871 create a transient block for it, to prevent premature finalization
5872 before the return is executed.
5873 (Gen_Assign): Do not generate a call to deep adjust routine if the
5874 component type is itself an array of controlled (sub)-components
5875 initialized with an inner aggregate.
5876 (Component_Check): New name for Static_Check. This name is now more
5877 appropriate, and documentation is added which was missing.
5878 (Component_Check): Add test for bit aligned component value
5879 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
5880 Tagged_Comps, name is more appropriate given added function below.
5881 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

5884 Javier Miranda <miranda@adacore.com>
5885 Robert Dewar <dewar@adacore.com>
5887 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
5888 Terminated: Add unchecked type conversion from System.Address to
5889 System.Tasking.Task_Id when calling the predefined primitive
5891 Disable new Ada 05 accessibility check for JVM.NET targets, which
5892 cannot be implemented in a practical way.
5893 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
5894 the sources always references the tag of the actual object. Therefore,
5895 if 'Tag is applied in the sources to class-wide interface objects we
5896 generate code that displaces "this" to reference the base of the object.
5897 (Expand_N_Attribute_Reference, case Size): Return specified size if
5899 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
5900 has code that displaces the pointer of the object to manage interface
5901 types. However this code must not be executed when the prefix is a
5902 subprogram. This bug caused the wrong expansion of the internally
5903 generated assignment that fills the dispatch table when the primitive
5904 is a function returning a class-wide interface type.
5905 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
5906 Set_Attribute_Name for Name_Unaligned_Valid.
5908 2007-06-06 Ed Schonberg <schonberg@adacore.com>
5909 Gary Dismukes <dismukes@adacore.com>
5911 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
5912 If the initialization is the equivalent aggregate of the initialization
5913 procedure of the type, do not remove it.
5914 (Expand_N_Attribute_Definition_Clause): Exclude access variables
5915 initialized to null from having their expression reset to empty and
5916 note this exception in the comment.

5920 Ed Schonberg <schonberg@adacore.com>
5921 Gary Dismukes <dismukes@adacore.com>
5923 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
5924 Add "with" and "use" clauses for Sem_Attr.
5925 (Expand_Current_Value): Do not replace occurences of attribute
5926 references where the prefix must be a simple name.
5928 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
5929 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
5930 Attribute_Requires_Simple_Name_Prefix.
5931 (Name_Modifies_Prefix): Body of new function.
5932 (Requires_Simple_Name_Prefix): Body of new function.
5933 (Resolve_Attribute, case Access): Improve error message for case of
5934 mismatched conventions.
5935 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
5937 (Analyze_Attribute, case 'Access): If the type of the prefix is a
5938 constrained subtype for a nominal unconstrained type, use its base type
5939 to check for conformance with the context.
5940 (Resolve_Attribute): Remove test of the access type being associated
5941 with a return statement from condition for performing accessibility
5942 checks on access attributes, since this case is now captured by
5943 Is_Local_Anonymous_Access.
5944 (Analyze_Access_Attribute): Set Address_Taken on entity
5945 (Analyze_Attribute, case Address): Set Address_Taken on entity
5946 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
5947 validating an access attribute whose prefix is a current instance.
5948 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
5949 applied to dispatching operations, if freezing is required then we set
5950 the attribute Has_Delayed_Freeze in the prefix's entity.
5951 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
5952 current scope if access of local subprogram taken
5953 (Analyze_Access_Attribute): Check legality of self-reference even if the
5954 expression comes from source, as when a single component association in
5955 an aggregate has a box association.
5956 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
5957 the prefix if it is a protected operation and the attribute is
5958 Unrestricted_Access.
5959 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
5960 reference to the base type of the context, to force a constraint check
5961 when the context is an access subtype with an explicit constraint.
5962 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
5963 node is rewritten as an interface conversion. leave unanalyzed after
5964 resolution, to ensure that type checking against the context will take

5968 Javier Miranda <miranda@adacore.com>
5969 Robert Dewar <dewar@adacore.com>
5971 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
5972 wrapper when the full view of the controlling type of an inherited
5973 function that dispatches on result implements interfaces.
5974 (Expand_N_Object_Declaration): In cases where the type of the
5975 declaration is anonymous access, create finalization list for it.
5976 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
5977 if the object has no explicit initialization, to match description of
5978 functionality of pragam Persistent_BSS.
5979 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
5980 new function to build static aggregates, to replace initialization call
5981 when static initialization is desired.
5982 (Freeze_Type): Generate a list controller for an access type whenever
5983 its designated type has controlled anonymous access discriminants.
5984 (Build_Equivalent_Aggregate): New procedure to compute a static
5985 aggregate to be used as default initialization for composite types,
5986 instead of a generating a call to the initialization procedure for the
5988 (Build_Initialization_Call): When available, replace a call to the
5989 initialization procedure with a copy of the equivalent static aggregate
5991 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
5992 declarations for objects of a class-wide interface type, rather than
5993 just identifiers, to prevent visibility problems.
5994 (Expand_N_Object_Declaration): When expanding the declaration for an
5995 object of a class-wide interface type, preserve the homonym chain of
5996 the original entity before exchanging it with that of the generated
5997 renaming declaration.
5998 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
5999 active, because there is no way to handle the exception.
6000 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
6001 to do a minimum decoration of the Access_Disp_Table list.
6002 (Expand_Record_Controller): Avoid the addition of the controller between
6003 the component containing the tag of a secondary dispatch table and its
6004 adjacent component that stores the offset to the base of the object.
6005 This latter component is only generated when the parent type has
6006 discriminants ---documented in Add_Interface_Tag_Components).
6007 (Apply_Array_Size_Check): Removed, no longer needed.
6008 (Expand_N_Full_Type_Declaration): If the type has anonymous access
6009 components, create a Master_Entity for it only if it contains tasks.
6010 (Build_Init_Procedure): Suppress the tag assignment compiling under
6012 (Freeze_Record_Type): Remove code associated with creation of dispatch
6014 (Init_Secondary_Tags): Update type of actuals when generating calls to
6015 Ada.Tags.Set_Offset_To_Top
6016 (Stream_Operation_OK): Disable use of streams compiling under no
6018 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
6019 if Has_Init_Expression set.
6020 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
6021 Register_Primitive, which provides the same functionality.
6022 (Requires_Init_Proc): Return false in case of interface types.
6023 (Add_Secondary_Tables): Use the new attribute Related_Interface to
6025 (Predefined_Primitive_Freeze): Do not assume that an internal entity
6026 is always associated with a predefined primitive because the internal
6027 entities associated with interface types are not predefined primitives.
6028 Therefore, the call to Is_Internal is replaced by a call to the
6029 function Is_Predefined_Dispatching_Operation.
6030 (Make_Eq_If): When generating the list of comparisons for the
6031 components of a given variant, omit the controller component that is
6032 present if the variant has controlled components.
6034 2007-06-06 Javier Miranda <miranda@adacore.com>
6035 Hristian Kirtchev <kirtchev@adacore.com>
6036 Bob Duff <duff@adacore.com>
6038 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
6039 handle the creation of finalization lists and calls for nested
6040 coextensions when the root of the chains is part of a return statement.
6041 (Inside_A_Return_Statement): New function inside Complete_Coextension_
6043 (Expand_Record_Equality): Skip components that are interface types.
6044 (Displace_Allocator_Pointer): Add missing support for interface subtypes
6045 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
6046 with Rewrite_Coextension. Change the condition for detecting coextension
6048 (Is_Local_Access_Discriminant): Removed.
6049 (Rewrite_Coextension): New routine which rewrites a static coextension
6050 as a temporary and uses its unrestricted access in the construction of
6052 (Complete_Coextension_Finalization): New routine. Generate finalization
6053 attachment calls to all delayed coextensions.
6054 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
6055 the allocator is not a coextension itself and has delayed coextensions.
6056 If the current allocator is controlled, but also a coextension, delay
6057 the generation of the finalization attachment call.
6058 Rename local variable "Node" to "Nod" in order to avoid confusion with
6060 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
6061 limited types that are not inherently limited. Such an allocator is
6062 illegal, but is generated by the expander for a return statement, to
6063 copy the result onto the secondary stack. This is the only case where a
6064 limited object can be copied. Generate code to displace the pointer
6065 to the object if the qualified expression is a class-wide interface
6066 object. Such displacement was missing and hence the copy of the object
6068 (Apply_Accessibility_Check): Handle allocated objects initialized in
6070 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
6071 and Expand_Allocator_Expression. Allocating class-wide interface objects
6072 this routine displaces the pointer to the allocated object to reference
6073 the component referencing the corresponding secondary dispatch table.
6074 Expand_Allocator_Expression): Add missing support to allocate class-wide
6075 interface objects initialized with a qualified expression.
6076 (Get_Allocator_Final_List): Test for an anonymous access type that is a
6077 function result type, and use the finalization list associated with the
6078 function scope in that case (such an anonymous type should not be
6079 treated like an access parameter's type).

6082 Gary Dismukes <dismukes@adacore.com>
6083 Javier Miranda <miranda@adacore.com>
6085 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
6086 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
6087 required exception handler.
6088 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
6089 properly the case of a function whose return type is a limited
6090 class-wide interface type. Modify the code of the accessibility
6091 check to handle class-wide interface objects. In this case we need to
6092 displace "this" to reference the primary dispatch table to get access
6093 to the TSD of the object (to evaluate its accessibility level).
6094 (Expand_N_Extended_Return_Statement): Test for a tagged result type
6095 rather than a controlling result as one of the conditions for
6096 generating tests of the implicit BIP_Alloc_Form formal. The
6097 initialization assignment is also handled according to whether the
6098 result is tagged instead of controlling.
6099 In the case where the init assignment is inserted in the "then" part of
6100 the allocation conditional, rewrite the target to be a dereference of
6101 the implicit BIP_Object_Access formal.
6102 If the returned value is unconstrained and created on the secondary
6103 stack, mark the enclosing block and function so that the secondary
6104 stack is not reclaimed on return.
6105 Treat returns from functions with controlling results similarly to
6106 returns from functions with unconstrained result subtypes.
6107 If the object returned is unconstrained, and an allocator must be
6108 created for it, analyze the allocator once the block for the extended
6109 return is installed, to ensure that finalizable components
6110 of the expression use the proper finalization list. Guard the call to
6111 Move_Final_List with a check that there is something to finalize.
6112 (Make_Tag_Ctrl_Assignment): Use "old" handling
6113 of controlled type assignment for virtual machines, since new code uses
6114 unsupported features (such as direct access to bytes in memory).
6116 2007-06-06 Gary Dismukes <dismukes@adacore.com>
6117 Ed Schonberg <schonberg@adacore.com>
6119 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
6120 accessibility actual, check for the case of an aliased object that has
6121 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
6122 we fall into processing for the attribute rather than the name of the
6124 (Expand_Inline_Call): If an actual is a literal, and the corresponding
6125 formal has its address taken in the body, create a temporary to capture
6126 value. If the return type is a limited interface, do not treat the
6127 return value as Controlled.
6128 (Is_In_Place_Function): If the return type is a limited interface,
6129 treat as returning in place. The actual returned object may not always
6130 be limited, but the caller has to assume that it is returned in place.
6131 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
6132 context of an allocator, use the correct finalization chain (that is,
6133 the chain belonging to the access type, rather than the chain belonging
6134 to the current scope).
6135 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
6136 result type rather than a controlling result as a precondition for
6137 adding an allocation form actual to a build-in-place call.
6138 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
6139 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
6140 primitive in the dispatch tables. This work is now done by Make_DT when
6142 (Register_Predefined_DT_Entry): Removed.
6143 (Add_Return): If end label is not present, use sloc of last statement
6144 for generated return statement in procedure, for better gdb behavior
6146 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
6147 object address nodes to ensure proper processing by routines like
6149 (Expand_Call): Fix generation of validity check for parameter
6150 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
6151 the allocation form parameter if the result subtype is constrained,
6152 except when the function has a controlling result.
6153 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
6154 rather than Is_Controlled and Has_Controlled_Component, since we want to
6155 include class-wide result types in this treatment. Also test for a
6156 controlling result, since that also requires passing a finalization
6158 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
6159 even when the result subtype is constrained, to handle calls involving
6160 controlling results.
6161 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
6162 is now called even when the result subtype is constrained, to handle
6163 calls involving controlling results.
6164 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
6165 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
6166 now performs the test).
6167 (Make_Build_In_Place_Call_In_Object_Declaration):
6168 Add_Alloc_Form_Actual_* is now called even when the result subtype is
6169 constrained, to handle calls involving controlling results.
6170 (Add_Return): Accomodate rewritten pattern from local raise to goto
6171 transformation, so that we still recognize an transfer statement
6172 and do the right thing here in that case.
6173 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
6174 and end of subprogram code.
6175 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
6176 support for primitives that are functions (without formals) with a
6178 (Inherited_From_Formal): If the actual subtype has not generic parent
6179 type, it is not an actual for a formal derived type, and there is no
6180 operation to inherit from the formal.
6182 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6183 Thomas Quinot <quinot@adacore.com>
6185 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
6186 inserted cleanup code appropriately for GDB use.
6187 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
6188 exception handler for Deep_Adjust or Deep_Finalize.
6189 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
6190 Raise_From_Controlled_Operation is available, use a call to that
6191 subprogram instead of a plain "raise Program_Error" node to raise
6192 Program_Error if an exception is propagated from an Adjust or Finalize
6194 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
6195 appears in the optional statement list of a triggering alternative, the
6196 scope actions can be inserted directly there, and not in the list that
6197 includes the asynchronous select itself.
6199 2007-06-06 Ed Schonberg <schonberg@adacore.com>

6201 Hristian Kirtchev <kirtchev@adacore.com>
6203 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
6204 generated exception handler appropriately when debugging generated code.
6205 Deal properly with No_Exception_Propagation restriction mode.
6206 (Expand_N_Abort_Statement): Add an unchecked type conversion from
6207 System.Address to System.Tasking.Task_Id when processing the result of
6208 the predefined primitive _disp_get_task_id.
6209 (Expand_N_Asynchronous_Select): Clarify comment.
6210 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
6211 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
6212 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
6213 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
6214 privals and for generated call to Complete_Entry_Body, for better gdb
6216 (Copy_Result_Type): Utility to construct a parameter and result profile
6217 for protected functions whose return type is an anonymous access to
6219 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
6221 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
6222 point when the local-raise-to-goto transformation has taken place.
6224 2007-06-06 Javier Miranda <miranda@adacore.com>
6225 Nicolas Setton <setton@adacore.com>
6227 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
6228 functionality when the backend is generating code.
6229 Otherwise any serious error
6230 reported by the backend calling the frontend routine Error_Msg
6231 changes the Compilation_Mode to Check_Semantics, disables the
6232 functionality of this routine and causes the generation of
6233 spureous additional errors.
6235 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
6236 debugging information now generated by the compiler for fat-pointer
6238 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
6240 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
6242 2007-06-06 Thomas Quinot <quinot@adacore.com>
6244 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
6245 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
6246 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
6247 For a remote call to a function with a classwide return type, apply an
6248 E.4(18) check to the returned value.
6249 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
6250 stream attributes of the designated type of an RACW, as they are not
6251 dispatching primitive operations.
6253 2007-06-06 Geert Bosch <bosch@adacore.com>
6255 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
6257 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
6259 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
6260 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
6262 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
6264 2007-06-06 Javier Miranda <miranda@adacore.com>
6266 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
6267 attribute compiling package Ada.Tags under No_Run_Time_Mode.
6269 2007-06-06 Javier Miranda <miranda@adacore.com>
6271 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
6272 deallocation of class-wide interface objects.
6273 (Expand_Dispatching_Constructor_Call): Take into account that if the
6274 result of the dispatching constructor is an interface type, the
6275 function returns a class-wide interface type; otherwise the returned
6276 object would be actual. The frontend previously accepted returning

8201 build-in-place functions with result type with controlled parts.
8202 Remove no longer used entities.
8204 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
8205 longer needed, because the full type is now limited, and therefore a

8238 to handle properly the anonymous access case.
8240 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
8241 for all access attributes, because overload resolution should work the
8242 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
8243 causes the error message for the ambiguous "X'Access = Y'Access" and
8244 "X'Unrestricted_Access = Y'Access" and so forth to match.
8245 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
8246 now that anonymous access to protected operations have their own kind.

8259 Derived_Type for Prev formal on call to
8260 Check_Anonymous_Access_Components rather than Empty.
8261 (Make_Incomplete_Type_Declaration): Add test for case where the type has
8262 a record extension in deciding whether to create a class-wide type,

8277 a call to Check_Abstract_Interfaces to verify the ARM rules.
8278 (Derive_Interface_Subprograms): Modified to support concurrent types
8279 with abstract interfaces.

8308 (Compile_Sources): Do nothing, not even check if the source is up to
8309 date, if its project is externally built.
8310 (Compile): When compiling a predefined source, add -gnatpg
8311 as the second switch, after -c.
8312 (Compile_Sources): Allow compilation of Annex J renames without -a
8313 (Is_In_Object_Directory): Check if the ALI file is in the object
8314 even if there is no project extension.

8316 gnatbind if the ALI file effectively exists.
8317 (Initialize): Add the directory where gnatmake is invoked in front of
8318 the path if it is invoked from a bin directory, even without directory
8319 information, so that the correct GNAT tools will be used when spawned
8320 without directory information.

8343 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
8344 when -gnatg is not specified.

8346 there is no need to generate always a record_definition_node in case
8347 of synchronized interface types.
8348 (SIS_Entry_Active): Initialize global variable to False
8349 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

8375 discriminant and the type is controlled. do not place on a finalization
8376 list at this point. The proper list will be determined from the

8394 same scope level as the allocator's type. The check is guaranteed to
8395 succeed in that case, even when the expression originates from a
8396 parameter of the containing subprogram.
8397 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
8398 under No_Dispatching_Calls restriction. During the semantic analysis
8399 we already notified such violation.
8400 (Tagged_Membership): Constant folding. There is no need to check
8401 the tag at run-time if the type of the right operand is non
8402 class-wide abstract.

8414 run-time subprogram Get_Access_Level by call to Build_Get_Access_Level.
8416 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
8417 initialize most the TSD components by means of an aggregate.
8418 Modify the declaration of the object containing the TSD
8419 because we now expand code that has a higher level of abstraction.
8420 The TSD has a discriminant containing the Inheritance Depth Level,
8421 value that is used in the membership test but also to fix the size
8422 of the table of ancestors.
8423 (Expand_Interface_Conversion): Insert function body at the closest place
8424 to the conversion expression, to prevent access-before-elaboration
8425 errors in the backend.

8453 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
8455 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
8456 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

8466 returns an actual parameter expression for both named and positional
8469 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
8470 check violation of restriction No_Dispatching_Calls.
8471 (Check_Controlling_Type): A formal of a tagged incomplete type is a

8475 First/Next_Component_Or_Discriminant
8476 (Insert_Actions): Add entries for new N_Push and N_Pop nodes

8478 specify Any_Limited_Interface, and this functionality is already
8479 provided by the function Has_Abstract_Interfaces.
8480 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
8481 support concurrent types implementing interfaces.
8482 (Find_Implemented_Interface): Removed. All the calls to this subprogram

8484 provided by the function Has_Abstract_Interfaces.
8485 (Remove_Side_Effects): replace Controlled_Type by
8486 CW_Or_Controlled_Type whenever the issue is related to
8487 using or not the secondary stack.
8489 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
8490 P_Interface_Type_Definition to fulfill the new interface (the formal
8491 Is_Synchronized is no longer required).

8502 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
8503 anonymous, use finalization list of enclosing dynamic scope.
8504 (Expand_N_Package_Declaration): For a library package declaration
8505 without a corresponding body, generate RACW subprogram bodies in the
8506 spec (just as we do for the task activation call).
8507 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
8508 Is_Abstract_Type. Make sure these are called only when appropriate.

8526 Family_Size with 'Cap' set to true.
8527 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
8528 a protected version of an operation declared in the private part of
8529 a protected object, because they may be invoked through a callback.
8530 (Set_Privals): If the type of a private component is an anonymous access
8531 type, do not create a new itype for each protected body.
8532 If the body of a protected operation creates
8533 controlled types (including allocators for class-widetypes), the
8534 body of the corresponding protected subprogram must include a
8536 (Build_Activation_Chain_Entity): Build the chain entity for extended
8538 (Type_Conformant_Parameters): Use common predicate Conforming_Types
8539 to determine whether operation overrides an inherited primitive.

8541 for a possible overriding candidate.
8542 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
8543 hold an actual parameter value since its initialization is separated
8544 from the the declaration. Prevents errors on null-excluding access

8552 Build_From_Any_Call.
8553 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
8554 E_Constant, depending upon Variable formal.
8555 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
8556 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
8557 parameter that requires an extra constrained parameter, declare
8558 temporary for actual as a variable, not a constant.
8559 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
8560 the unit being compiled is the one that contains the stub type.
8561 Change primitive operation name for the RACW associated with a RAS
8562 from Call to _Call so it cannot clash with any legal identifier.
8563 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
8565 (Append_RACW_Bodies): New subprogram.
8566 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
8567 Add_Receiving_Stubs_To_Declarations functions.
8568 When expanding a package body, this list correspond to the
8569 statements in the HSS at the end of the pacakge.
8570 When expanding a package spec, this list correspond to the
8572 (Add_Receiving_Stubs_To_Declarations): Append the function
8573 registering the receiving stubs at the end of the 'Stmts' list.
8574 (RCI_Package_Locator): Pass the new Version generic formal when
8575 instantiating a RCI_Locator package.
8576 (Build_From_Any_Function): To compute the High bound for an
8577 unconstrained array actual, we add the Low bound with the length.
8578 Thus we must convert the low bound and the length to an appropriate
8579 type before doing the sum.
8580 (Build_Subprogram_Receiving_Stubs, PolyORB):
8581 * Retrieve the extra formals parameters at the
8582 end of the parameter stream.
8583 * Use Move_Any_Value to write back out parameters
8584 after executing the request as it is more efficient
8585 than Copy_Any_Value.
8586 * Build the any containing Extra Formals with the
8587 appropriate typecode.
8588 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
8589 empty Component_List.
8590 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
8591 the tree the declaration for an object that serves as actual parameter
8592 in server-side stubs.

8602 function with the first not implicit parent type.
8603 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
8604 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
8605 typecode from the Etype. Therefore we retrieve the correct typecode
8606 with a call to Get_Any_Type.
8607 (Copy_Specification): Do controlling formal type substitution based on
8608 Is_Controlling_Formal flag, instead of caller-provided object type.
8609 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
8610 a RACW primitive operation, we might get a subprogram declaration for an
8611 ancestor of the RACW designated type (not for the designated type
8612 itself), in the case where this operation is inherited. In this case we
8613 have no easy means of determining the original tagged type for which
8614 the primitive was declared, so instead we now rely on
8615 Copy_Specification to use the Is_Controlling_Formal flag to determine
8616 which formals require type substitution.

8626 run-time subprogram CW_Membership by call to Build_CW_Membership.
8627 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
8628 by a function call, a temporary must be created before expanding the
8629 Constructor_Call itself, to prevent out-of-order elaboration in the
8630 back-end when stack checking is enabled..

8813 __gnat_adjust_context_for_raise.
8814 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
8815 implementation of floating point operations as native x86 targets.

8817 floating point operations accuracy issues.
8818 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
8819 member in struct sigaction, so as to avoid warning for incompatible

8838 Modify the loop that collects type references, to include interface
8839 types that the type implements. List each of these interfaces when
8840 building the entry for the type.
8841 (Generate_Definition): Initialize component Def and Typ of new entry
8842 in table Xrefs, to avoid to have these components unitialized.

9051 (Install_Limited_With_Clauses): Do not install non-limited view when it
9052 is still incomplete.

9055 Gary Dismukes <dismukes@adacore.com>
9057 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
9058 when capturing size information, instead of base type, which for a
9059 formal array type will be the unconstrained type.
9060 (Analyze_Formal_Object_Declaration): Add check for illegal default
9061 expressions for a formal in object of a limited type.
9062 (Instantiate_Object): Ditto.
9063 (Check_Formal_Package_Instance): Skip entities that are formal objects,
9064 because they were defaulted in the formal package and no check applies
9066 (Check_Formal_Package_Instance): Extend conformance check to other
9067 discrete types beyond Integer.
9068 (Process_Default): Copy directly the unmatched formal. A generic copy
9069 has already been performed in Analyze_Formal_Package.
9070 (Analyze_Associations): If a formal subprogram has no match, check for
9071 partial parametrization before looking for a default, to prevent
9073 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
9074 not set the instantiation environment before analyzing the actuals.
9075 Fixes regression on 8515-003 with implementation of AI-133.
9076 Set_Instance_Env checks whether the generic unit is a predefined
9077 unit, in which case the instance must be analyzed with the latest Ada
9078 mode. This setting must take place after analysis of the actuals,
9079 because the actuals must be analyzed and frozen in the Ada mode extant
9080 outside of the current instantiation.
9081 (Save_Env, Restore_Env): Preserve and restore the configuration
9082 parameters so that predefined units can be compiled in the proper Ada
9084 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,

9093 Gary Dismukes <dismukes@adacore.com>
9095 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
9096 prefix type is a discriminated subtype of the type of the formal.
9097 (Analyze_Allocator): Collect all coextensions regardless of the context.
9098 Whether they can be allocated statically is determined in exp_ch4.
9099 (Analyze_Selected_Component): If the prefix is a limited view and the
9100 non-limited view is available, use the non-limited one.
9101 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
9102 therefore illegal), suggest a qualified expression rather than a type
9103 conversion, because a type conversion would be illegal in this context.
9104 (Anayze_Allocator): Trace recursively all nested allocators so that all
9105 coextensions are on the corresponding list for the root. Do no mark
9106 coextensions if the root allocator is within a declaration for a stack-
9107 allocated object, because the access discriminants will be allocated on
9109 (Analyze_Call): Remove restriction on calls to limited functions for the
9110 cases of generic actuals for formal objects, defaults for formal objects
9111 and defaults for record components.
9112 (Analyze_Allocator): Before analysis, chain coextensions on the proper
9113 element list. Their expansion is delayed until the enclosing allocator
9114 is processed and its finalization list constructed.
9115 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
9116 for an operation with the given name among the primitive operations of
9117 the corresponding record type.
9118 (Analyze_Selected_Component): If the prefix is a task type that
9119 implements an interface, and there is no entry with the given name,

9122 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
9123 properly the indexing of a function call written in prefix form, where
9124 the function returns an array type, and all parameters of the function
9125 except the first have defaults.
9126 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
9127 the original operands, rather than relocating them, for efficiency and
9128 to work properly when an operand is overloaded.

9165 identifier, and be special-cased in Check_Completion.
9166 Mark the full view of the designated type for the RACW associated with
9167 a RAS as Comes_From_Source to get proper view switching when installing
9168 private declarations.
9169 Provite a placeholder nested package body along with the nested spec
9170 to have a place for Append_RACW_Bodies to generate the calling stubs
9171 and stream attributes.

9202 object O, use the access level of O.
9203 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
9204 rather than local Same_Formal_Type, to check whether protected operation
9205 overrides an inherited one.
9206 (Same_Formal_Type): New predicate, used when matching signatures of
9207 overriding synchronized operations, to handle the case when a formal
9208 has a type that is a generic actual.
9209 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
9210 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.

9226 same result than Is_Ancestor.
9227 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
9228 (Collect_Synchronized_Interfaces): Removed because the subprogram
9229 Collect_Abstract_Interfaces provides this functionality.

9231 concurrent types and thus avoid undesired code duplication.
9232 (Get_Subprogram_Entity): Handle entry calls.
9233 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
9235 (Enter_Name): Do not give -gnatwh hiding warning for record component

9277 operation applies to a private type whose full view is a modular type.
9278 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
9279 Address_Clause, use the associated Expression as the GNAT tree
9280 representing the choice value to ensure the corresponding GCC tree is
9282 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
9283 instead of just the operands, as the base GCC stabilize_reference does.
9284 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not

9548 Add some \\ sequences to continuation messages
9549 (Resolve_Call): Refine infinite recursion case. The test has been

9565 Valid_Conversion, to incorporate accessibility checks for arrays of
9566 anonymous access types.
9567 (Valid_Conversion): For a conversion to a numeric type occurring in an
9568 instance or inlined body, no need to check that the operand type is
9569 numeric, since this has been checked during analysis of the template.

10084 sem_util and renamed as Collect_All_Abstract_Interfaces.
10085 (Set_All_DT_Position): Hidden entities associated with abstract
10086 interface primitives are not taken into account in the check for

10098 alias of a predefined dispatching primitive.
10099 (Make_DT): If the ancestor of the type is a CPP_Class and we are
10100 compiling under full ABI compatibility mode we avoid the generation of
10101 calls to run-time services that fill the dispatch tables because under
10102 this mode we currently inherit the dispatch tables in the IP subprogram.
10103 (Write_DT): Emit an "is null" indication for a null procedure primitive.
10104 (Expand_Interface_Conversion): Use an address as the type of the formal
10105 of the internally built function that handles the case in which the

10156 we request a discriminal value only in case of discriminants.
10157 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
10158 assignments where the target subtype is unconstrained and the target
10159 object is a parameter or dereference (other aliased cases are known

10276 are build-in-place function calls.
10277 (Replace_Self_Reference): New subsidiary of
10278 Make_OK_Assignment_Statement, to replace an access attribute that is a
10279 self-reference into an access to the appropriate component of the
10280 target object. Generalizes previous mechanism to handle self-references
10281 nested at any level.
10282 (Is_Self_Referential_Init): Remove, not needed.

10289 default initialization.
10290 (Make_OK_Assignment_Statement): If the expression is of the form
10291 Typ'Acc, where Acc is an access attribute, the expression comes from a
10292 default initialized self-referential component.
10293 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
10294 that has been derived from several abstract interfaces we must also

10300 Robert Dewar <dewar@adacore.com>
10303 (Expand_Access_To_Protected_Op): If the context indicates that an access
10304 to a local operation may be transfered outside of the object, create an
10305 access to the wrapper operation that must be used in an external call.
10306 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
10307 target, pass the Valid attribute applied to a floating-point prefix on
10308 to the back end without expansion.

10323 subcomponent's enclosing variable is aliased with a constrained subtype.
10324 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
10325 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
10326 an aliased prefix must be known to be constrained in order to use True
10327 for the attribute value, and now it's possible for some aliased views
10328 to be unconstrained.
10330 2006-10-31 Robert Dewar <dewar@adacore.com>
10332 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue

10343 otherwise we incorrectly register the tag of the interface in the final
10345 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
10346 generate the wrapper if the parent primitive is abstract. This is
10347 required to report the correct error message.
10348 (Expand_N_Subtype_Indication): Do validity checks on range
10349 (Clean_Task_Names): If an initialization procedure includes a call to

10358 call to build-in-place function and apply Make_Build_In_Place_Call_In_
10359 Object_Declaration to the call.
10360 (Freeze_Type): When the designated type of an RACW was not frozen at the
10361 point where the RACW was declared, validate the primitive operations
10362 with respect to E.2.2(14) when it finally is frozen.
10363 (Build_Initialization_Call,Expand_Record_Controller): Rename
10364 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
10365 return-by-reference has no meaning in Ada 2005.

10367 to register tag of the immediate ancestor interfaces in the
10368 run-time structure.

10370 initialization of extension aggregates with abstract interfaces.
10371 (Build_Master_Renaming): Make public, for use by function declarations
10372 whose return type is an anonymous access type.
10373 (Freeze_Record_Type): Replace call to Insert_List_Before by call to

10377 (Init_Secondary_Tags): Update documentation.
10378 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
10379 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
10380 then generate code to inherit the contents of the dispatch table
10381 directly from the ancestor.
10382 (Expand_Record_Controller): Insert controller component after tags of
10383 implemented interfaces.
10384 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to

10388 declarations for overriding null primitives inherited from interfaces.
10389 (Is_Null_Interface_Procedure): New function in
10390 Make_Null_Procedure_Specs.
10391 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
10392 immediate ancestor of a tagged type is an abstract interface type we
10393 must generate the specification of the predefined primitives associated
10394 with controlled types (because the dispatch table of the ancestor is
10395 null and hence these entries cannot be inherited). This is required to
10396 elaborate well the dispatch table.

10410 the maximum for type T.
10411 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
10412 when the allocator is initialized by a build-in-place call, since the
10413 allocator is already rewritten as a reference to the function result,
10414 and this prevents an unwanted duplication of the function call.
10415 Add with and use of Exp_Ch6.
10416 (Expand_Allocator_Expresssion): Check for an allocator whose expression
10417 is a call to build-in-place function and apply
10418 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
10419 untagged designated types).
10420 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
10421 optimization if source or target is biased.
10422 (Expand_N_Allocator): Add comments for case of an allocator within a

10435 (Expand_N_Assignment_Statement): Call
10436 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a

10440 in order to alleviate the upward compatibility introduced by AI-318.
10441 (Expand_N_Extended_Return_Statement): Add support for handling the
10442 return object as a build-in-place result.
10443 (Expand_Non_Function_Return): Implement simple return statements nested
10444 within an extended return.
10445 (Enable_New_Return_Processing): Turn on the new processing of return
10447 (Expand_Non_Function_Return): For a return within an extended return,

10455 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
10456 validity checking of assignments to elementary record components.
10457 (Expand_N_Return_Statement): return Class Wide types on the secondary
10458 stack independantly of their controlled status since with HIE runtimes,
10459 class wide types are not potentially controlled anymore.
10461 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
10464 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
10465 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
10466 it expects a block, procedure, or task. The return statement will get
10467 turned into a block, and Expand_Cleanup_Actions will happen then.

10474 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
10476 (Expand_Inlined_Call): Tagged types are by-reference types, and
10477 therefore should be replaced by a renaming declaration in the expanded
10478 body, as is done for limited types.
10479 (Expand_Call): If this is a call to a function with dispatching access
10480 result, propagate tag from context.
10481 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
10483 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
10484 build-in-place when the right-hand side of an assignment is a
10485 build-in-place function call.
10486 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
10487 of the explicit dereference of the allocator to the result subtype of
10488 the build-in-place function. This is needed to satisfy type checking
10489 in cases where the caller's return object is created by an allocator for
10490 a class-wide access type and the type named in the allocator is a
10492 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
10493 conversion of the reference to the declared object to the result subtype
10494 of the build-in-place function. This is needed to satisfy type checking
10495 in cases where the declared object has a class-wide type. Also, in the
10496 class-wide case, change the type of the object entity to the specific
10497 result subtype of the function, to avoid passing a class-wide object
10498 without explicit initialization to the back end.
10499 (Register_Interface_DT_Entry): Moved outside the body of
10500 Freeze_Subprogram because this routine is now public; it is called from
10501 Check_Dispatching_Overriding to handle late overriding of abstract
10502 interface primitives.
10503 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
10504 adding an implicit access actual on a call to a build-in-place function.
10505 (Expand_Actuals): Test for an actual parameter that is a call to a
10506 build-in-place function and apply
10507 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
10508 (Is_Build_In_Place_Function): New function to determine whether an
10509 entity is a function whose calls should be handled as build-in-place.
10510 (Is_Build_In_Place_Function_Call): New function to determine whether an
10511 expression is a function call that should handled as build-in-place.
10512 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
10513 calls to build-in-place functions as the initialization of an allocator.
10514 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
10515 handling calls to build-in-place functions in contexts that do not
10516 involve init of a separate object (for example, actuals of subprogram
10518 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
10519 handling calls to build-in-place functions as the initialization of an
10520 object declaration.
10521 (Detect_Infinite_Recursion): Add explicit parameter Process to
10522 instantiation of Traverse_Body to avoid unreferenced warning.
10523 (Check_Overriding_Inherited_Interfaces): Removed.
10524 (Register_Interface_DT_Entry): Code cleanup.
10525 (Register_Predefined_DT_Entry): Code cleanup.
10526 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
10527 inlined statements if within a transient scope.
10528 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
10529 formal parameters with occurrences of actuals in inlined body, establish
10530 visibility on the proper view of the actual's subtype for the body's
10532 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
10533 compatibility mode and we have an imported CPP subprogram because
10534 for now we assume that imported CPP primitives correspond with
10535 objects whose constructor is in the CPP side (and therefore we
10536 don't need to generate code to register them in the dispatch table).
10537 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
10538 aligned selected component.
10539 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
10540 the actual of an in-mode parameter is a type conversion.
10541 (Expand_Actuals): If the call does not come from source and the actual
10542 is potentially misaligned, let gigi handle it rather than rejecting the
10543 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
10544 Class Wide types as returning by reference independantly of their
10545 controlled status since with HIE runtimes class wide types are not
10546 potentially controlled anymore.

10561 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
10562 initialization of Homonym_Len.
10563 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
10564 names from fully qualified name. Fixes problem of duplicate
10565 external names differing only in the presence of such a block name.

10568 Pablo Oliveira <oliveira@adacore.com>
10570 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
10571 subprogram Ids, even if they are not yet assigned.
10572 (Build_Subprogram_Id): It is now this function that will take care of
10573 calling Assign_Subprogram_Ids if necessary.
10574 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
10575 should be done only once they are assigned.
10576 (Build_From_Any_Function, case of tagged types): Add missing call to
10578 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
10579 type for an RACW type.
10580 (Add_RACW_Features): When processing an RACW declaration for which the
10581 designated type is already frozen, enforce E.2.2(14) rules immediately.
10582 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
10583 special reordering of controlling formals.
10585 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
10586 associated stub type for an RACW type.
10588 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10590 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
10591 fixed-point operations in an integer context, i.e. as operands of a
10592 conversion to an integer type, indicate that result must be rounded.
10594 2006-10-31 Robert Dewar <dewar@adacore.com>
10596 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
10597 cases, pass the encoding method, since it is now required by the run
10600 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
10601 assumption that Str'First = 1.
10602 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
10603 it on to the Value_Wide_Wide_Character call.
10604 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
10605 properly handles a string of the form quote-encoded_wide_char-quote.
10607 * s-wchcnv.adb: Minor reformatting
10609 2006-10-31 Javier Miranda <miranda@adacore.com>
10611 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
10612 run-time membership test to ensure that the constructed object
10613 implements the target abstract interface.
10615 2006-10-31 Robert Dewar <dewar@adacore.com>
10617 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
10618 Machine_Attribute pragma internally to implement the user pragma.
10619 Add processing for pragma Interface so that it is now completely
10620 equivalent to pragma Import.
10622 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
10623 so that it can be applied to all entities, including record components
10624 and enumeration literals.
10625 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
10626 priority ranges are correct, verify compatibility against task
10627 dispatching and locking policies, and if everything is correct an entry
10628 is added to the table containing priority specific dispatching entries
10629 for this compilation unit.
10630 (Delay_Config_Pragma_Analyze): Delay processing
10631 Priority_Specific_Dispatching pragmas because when processing the
10632 pragma we need to access run-time data, such as the range of
10633 System.Any_Priority.
10634 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
10635 Allow pragma Unreferenced as a context item
10636 Add pragma Preelaborable_Initialization
10637 (Analyze_Pragma, case Interface): Interface is extended so that it is
10638 now syntactically and semantically equivalent to Import.
10639 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
10640 insertion characters.
10641 Add handling for Pragma_Wide_Character_Encoding
10642 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
10643 never supercedes a real restriction, and that a real restriction
10644 always supercedes a warning.
10645 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

10652 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
10653 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
10654 Is_Inherently_Limited_Type, because return-by-reference has no meaning
10656 (Find_Node_To_Be_Wrapped): Use new method of determining the result
10657 type of the function containing a return statement, because the
10658 Return_Type field was removed. We now use the Return_Applies_To field.
10660 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
10661 (Build_Task_Image_Decl): If procedure is not called from an
10662 initialization procedure, indicate that function that builds task name
10663 uses the sec. stack. Otherwise the enclosing initialization procedure
10664 will carry the indication.
10665 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
10666 N_Object_Declaration instead.
10667 (Kill_Dead_Code): New interface to implement -gnatwt warning for
10668 conditional dead code killed, and change implementation accordingly.
10669 (Insert_Actions): Add N_Return_Object_Declaration case.
10670 Correct comment to mention N_Extension_Aggregate node.
10671 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
10672 attempts to save information for global variables which cannot be
10674 (Get_Current_Value_Condition): Handle conditions the other way round
10675 (constant on left). Also handle right operand of AND and AND THEN
10676 (Set_Current_Value_Condition): Corresponding changes
10677 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
10678 (Get_Current_Value_Condition): Handle simple boolean operands
10679 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
10680 (Get_Current_Value_Condition): If the variable reference is within an
10681 if-statement, does not appear in the list of then_statments, and does
10682 not come from source, treat it as being at unknown location.
10683 (Get_Current_Value_Condition): Enhance to allow while statements to be
10684 processed as well as if statements.
10685 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
10687 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
10688 of loop. This is safe now that we fixed Kill_Current_Values.
10689 (OK_To_Do_Constant_Replacement): Check whether current scope is
10690 Standard, before examining outer scopes.
10692 2006-10-31 Vincent Celier <celier@adacore.com>
10694 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
10695 When True, apply VMS treatment to children of packages A, G, I and S.

10712 (Generate_Reference): Centralize handling of pragma Obsolescent here
10713 (Generate_Reference): Accept an implicit reference generated for a
10714 default in an instance.
10715 (Generate_Reference): Accept a reference for a node that is not in the
10716 main unit, if it is the generic body corresponding to an subprogram
10719 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
10721 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
10723 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
10725 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
10726 use clauses, to avoid messages on packages used to qualify, and also
10727 to avoid messages from obsolescent units.
10728 (Warn_On_Useless_Assignments): Don't generate messages for imported
10729 and exported variables.
10730 (Warn_On_Useless_Assignments): New procedure

10735 Change name Is_Ada_2005 to Is_Ada_2005_Only
10736 (Last_Assignment): New field for useless assignment warning
10738 2006-10-31 Olivier Hainque <hainque@adacore.com>
10740 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
10741 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.

10744 Robert Dewar <dewar@adacore.com>
10745 Ed Schonberg <schonberg@adacore.com>
10747 * g-awk.adb (Default_Session, Current_Session): Compile this file in
10748 Ada 95 mode, because it violates the new rules for AI-318.
10750 * g-awk.ads: Use overloaded subprograms in every case where we used to
10751 have a default of Current_Session. This makes the code closer to be
10752 correct for both Ada 95 and 2005.
10754 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
10755 code, relying on the fact that the compiler generates a warning
10756 instead of an error in -gnatg mode.
10758 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
10759 E_Return_Statement entity kind.
10760 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
10762 * par.adb (P_Interface_Type_Definition): Addition of one formal to
10763 report an error if the reserved word abstract has been previously found.
10764 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
10766 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
10767 parenthesized range attribute usage
10768 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
10770 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
10771 in the syntax for extended_return_statement. This is not in the latest
10772 RM, but the ARG is expected to issue an AI allowing this.
10773 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
10774 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
10775 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
10776 P_Return_Statement): Parse the new syntax for extended_return_statement.
10778 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
10779 Output_End_Missing): Add error-recovery code for the new
10780 extended_return_statement syntax; that is, the new E_Return entry on
10783 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
10784 limited to nonlimited, because otherwise we violate the new Ada 2005
10785 rules about returning limited types in function Create_AST_Handler in
10788 * sem.adb (Analyze): Add cases for new node kinds
10789 N_Extended_Return_Statement and N_Return_Object_Declaration.
10791 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
10792 type is in the same category as type of context before applying check,
10793 to prevent anomalies in instantiations.
10794 (Resolve_Aggregate): Remove test for limited components in aggregates.
10795 It's unnecessary in Ada 95, because if it has limited components, then
10796 it must be limited. It's wrong in Ada 2005, because limited aggregates
10798 (Resolve_Record_Aggregate): Move check for limited types later, because
10799 OK_For_Limited_Init requires its argument to have been resolved.
10800 (Get_Value): When copying the component default expression for a
10801 defaulted association in an aggregate, use the sloc of the aggregate
10802 and not that of the original expression, to prevent spurious
10803 elaboration errors, when the expression includes function calls.
10804 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
10805 were missing. We also didn't handle qualified expressions. Now also
10806 allow function calls. Use new common routine OK_For_Limited_Init.
10807 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
10808 with space can upper case letter).
10810 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
10811 Has_Static_Discriminants flag
10812 (Record_Type_Declaration): Diagnose an attempt to declare an interface
10813 type with discriminants.
10814 (Process_Range_Expr_In_Decl): Do validity checks on range
10815 (Build_Discriminant_Constraints): Use updated form of
10816 Denotes_Discriminant.
10817 (Process_Subtype): If the subtype is a private subtype whose full view
10818 is a concurrent subtype, introduce an itype reference to prevent scope
10820 (Build_Derived_Record_Type, Collect_Interface_Primitives,
10821 Record_Type_Declaration): The functionality of the subprograms
10822 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
10823 is now performed by a single routine.
10824 (Build_Derived_Record_Type): If the type definition includes an explicit
10825 indication of limitedness, then the type must be marked as limited here
10826 to ensure that any access discriminants will not be treated as having
10827 a local anonymous access type.
10828 (Check_Abstract_Overriding): Issue a detailed error message when an
10829 abstract subprogram was not overridden due to incorrect mode of its
10831 (Analyze_Private_Extension_Declaration): Add support for the analysis of
10832 synchronized private extension declarations. Verify that the ancestor is
10833 a limited or synchronized interface or in the generic case, the ancestor
10834 is a tagged limited type or synchronized interface and all progenitors
10835 are either limited or synchronized interfaces.
10836 Derived_Type_Declaration): Check for presence of private extension when
10837 dealing with synchronized formal derived types.
10838 Process_Full_View): Enchance the check done on the usage of "limited" by
10839 testing whether the private view is synchronized.
10840 Verify that a synchronized private view is completed by a protected or
10842 (OK_For_Limited_Init_In_05): New function.
10843 (Analyze_Object_Declaration): Move check for limited types later,
10844 because OK_For_Limited_Init requires its argument to have been resolved.
10845 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
10846 in order to alleviate the upward compatibility introduced by AI-318.
10847 (Constrain_Corresponding_Record): If the constraint is for a component
10848 subtype, mark the itype as frozen, to avoid out-of-scope references to
10849 discriminants in the back-end.
10850 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
10851 this subprogram against wrong sources.
10852 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
10853 discriminant of limited type completed with a protected type, when the
10854 discriminant is used to constrain a private component of the type, and
10855 expansion is disabled.
10856 (Find_Type_Of_Object): Do not treat a return subtype that is an
10857 anonymous subtype as a local_anonymous_type, because its accessibility
10858 level is the return type of the enclosing function.
10859 (Check_Initialization): In -gnatg mode, turn the error "cannot
10860 initialize entities of limited type" into a warning.
10861 (OK_For_Limited_Init): Return true for generated nodes, since it
10862 sometimes violates the legality rules.
10863 (Make_Incomplete_Declaration): If the type for which an incomplete
10864 declaration is created happens to be the currently visible entity,
10865 preserve the homonym chain when removing it from visibility.
10866 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
10867 inherited subprograms.
10868 (Access_Definition): If this is an access to function that is the return
10869 type of an access_to_function definition, context is a type declaration
10870 and the scope of the anonymous type is the current one.
10871 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
10872 incomplete subtype to the set of private dependents of the original
10874 (Constrain_Discriminated_Type): Emit an error message whenever an
10875 incomplete subtype is being constrained.
10876 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
10877 corresponding subtype of the full view of the original incomplete type.
10878 (Check_Incomplete): Properly detect invalid usage of incomplete types
10881 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
10883 * g-catiio.ads, g-catiio.adb (Value): New function.

10892 Robert Dewar <dewar@adacore.com>
10894 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
10895 handling executable extension manually and duplicating code.
10897 * make.adb: Implement new -S switch
10898 (Gnatmake): Use new function Osint.Executable_Name instead
10899 of handling executable extension manually.
10901 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
10902 is specified, the executable name ends with this suffix.
10903 Take advantage of Osint.Executable_Name instead of duplicating code.
10905 * switch-m.adb: Recognize new gnatmake -S switch
10907 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
10909 (Get_Target_Parameters): Set Executable_Extension_On_Target if
10912 * makeusg.adb: Add line for gnatmake -S switch
10914 2006-10-31 Vincent Celier <celier@adacore.com>
10916 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
10917 call it with -static-libgcc, as there are some platforms, such as
10918 Darwin, where one of these two switches is compulsory to link.
10920 2006-10-31 Vincent Celier <celier@adacore.com>
10922 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
10923 instead of ADA_PROJECT_PATH, for the project path.
10924 (Gnatls): When displaying the project path directories, use host dir
10927 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
10928 names in the project path, as absolute paths may correspond to
10929 multi-valued VMS logical names.
10931 2006-10-31 Vincent Celier <celier@adacore.com>
10933 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
10934 absolute path name.
10935 (Locate_Regular_File): Ditto
10936 (Change_Dir): Remove, no longer used
10937 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
10938 on Windows. Get it calling Get_Current_Dir.
10939 (OpenVMS): Remove imported boolean, no longer needed.
10940 (Normalize_Pathname)[VMS]: Do not resolve directory names.
10941 (Pid_To_Integer): New function to convert a Process_Id to Integer
10943 2006-10-31 Thomas Quinot <quinot@adacore.com>

10946 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
10948 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
10951 2006-10-31 Robert Dewar <dewar@adacore.com>
10953 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
10954 initial letter o as a zero.
10956 2006-10-31 Robert Dewar <dewar@adacore.com>
10958 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
10960 2006-10-31 Robert Dewar <dewar@adacore.com>
10962 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
10964 (Layout_Variant_Record): Retrieve the discriminants from the entity
10965 rather than from the type definition, because in the case of a full
10966 type for a private type we need to take the discriminants from the
10968 (Layout_Component_List): When applying the Max operator to variants with
10969 a nonstatic size, check whether either operand is static and scale that
10970 operand from bits to storage units before applying Max.
10971 (Layout_Type): In VMS, if a C-convention access type has no explicit
10972 size clause (and does not inherit one in the case of a derived type),
10973 then the size is reset to 32 from 64.
10975 2006-10-31 Vincent Celier <celier@adacore.com>
10977 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
10978 its file has already been loaded, according to the unit being loaded,
10979 not to the current value of Multiple_Unit_Index.
10981 2006-10-31 Thomas Quinot <quinot@adacore.com>
10982 Eric Botcazou <ebotcazou@adacore.com>
10983 Arnaud Charlet <charlet@adacore.com>
10985 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
10986 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
10988 (a-except.o): Pass it to the compiler.
10989 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
10990 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
10991 a-calend-mingw.adb version.

10994 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
10995 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
10996 Ada.Dispatching.Round_Robin.
10997 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
10999 * Make-lang.in: Remove all references to gt-ada-decl.h.
11000 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
11002 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
11003 Update dependencies.
11005 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
11007 2006-10-31 Vincent Celier <celier@adacore.com>
11009 * mlib-utl.adb (Initialized): Remove, no longer used
11010 (Initialize): Remove, no longer used
11011 (Ar): If Ar_Exec is null, get the location of the archive builder and,
11012 if there is one, the archive indexer. Fail if the archive builder cannot
11014 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
11017 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11019 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
11020 Process_Body_Clauses): If the context of a body includes a use clause
11021 for P.Q then a with_clause for P in the same body is not redundant,
11022 even if the spec also has a with_clause on P.
11023 Add missing continuation mark to error msg
11024 (Build_Limited_Views): A limited view of a type is tagged if its
11025 declaration includes a record extension.
11026 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
11027 node, even if the subunit has errors. This avoids malfunction by
11028 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
11029 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
11030 generation of obsolescent messages for with statements (cannot do
11031 this too early, or we cannot implement avoiding the messages in the
11032 case of obsolescent units withing obsolescent units).
11033 (Install_Siblings): If the with_clause is on a remote descendant of
11034 an ancestor of the current compilation unit, find whether there is
11035 a sibling child unit that is immediately visible.
11036 (Remove_Private_With_Clauses): New procedure, invoked after completing
11037 the analysis of the private part of a nested package, to remove from
11038 visibility the private with_clauses of the enclosing package
11040 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
11041 now centralized in Generate_Reference.
11042 (Install_Limited_Context_Clauses): Remove superfluous error
11043 message associated with unlimited view visible through use
11044 and renamings. In addition, at the point in which the error
11045 is reported, we add the backslash to the text of the error
11046 to ensure that it is reported as a single error message.
11047 Use new // insertion for some continuation messages
11048 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
11049 to create implicit with_clause for parent unit mentioned in original
11050 limited_with_clause.
11051 (Install_Limited_With_Unit): Set entity of parent identifiers if the
11052 unit is a child unit. For ASIS queries.
11053 (Analyze_Subunit): If the subunit appears within a child unit, make all
11054 ancestor child units directly visible again.

11066 Add the new actual Abstract_Present to every call to
11067 P_Interface_Type_Definition.
11068 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
11069 a formal object declaration with an access definition or a subtype mark
11070 with a null exclusion.
11071 (P_Generic_Association): Handle association with box, and others_choice
11072 with box, to support Ada 2005 partially parametrized formal packages.
11074 2006-10-31 Robert Dewar <dewar@adacore.com>
11075 Javier Miranda <miranda@adacore.com>
11077 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
11078 (P_Type_Declaration): Remove barrier against the reserved word "limited"
11079 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
11080 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
11081 private extensions.
11082 (P_Type_Declaration): Add the new actual Abstract_Present to every call
11083 to P_Interface_Type_Definition.
11084 (P_Interface_Type_Definition): Addition of one formal to report an error
11085 if the reserved word abstract has been previously found.
11086 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
11087 object renaming declaration with an access definition or subtype mark
11088 with a possible null exclusion.
11090 * par-ch9.adb: Minor error msg fix
11092 * par-load.adb: Add missing continuation mark to error msg
11094 * par-tchk.adb: (Wrong_Token): Code cleanup, use concatenation

11098 * prj-dect.adb (Parse_Attribute_Declaration): Do not issue warning for
11099 unknown attribute in unknown package or in package that does not need
11101 (Parse_Package_Declaration): Do not issue warning for unknown package in
11104 2006-10-31 Vincent Celier <celier@adacore.com>
11106 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
11107 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
11110 2006-10-31 Vincent Celier <celier@adacore.com>
11112 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
11113 on VMS, change "__" to '.' before checking the name.
11114 (Record_Ada_Source): Always add the source file name in the list of
11115 of sources, even if it is not the first time, as it is for another
11117 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
11118 dot, instead of replacing only the first '_'.
11120 * prj-part.adb (Parse): Convert project file path to canonical form
11122 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
11123 extended, the project id of the project extending it is recorded in its
11124 data, even when it has already been processed as an imported project.
11126 2006-10-31 Robert Dewar <dewar@adacore.com>
11128 * repinfo.adb (List_Entities): Don't list entities from renaming
11131 2006-10-31 Arnaud Charlet <charlet@adacore.com>
11132 Robert Dewar <dewar@adacore.com>
11134 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
11135 only a restriction warning is active for the given restriction. This is
11136 desirable because we do not want to modify code in the case where only
11138 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
11139 causes overriding of real restrictions.
11140 Take advantage of new No_Restrictions constant.
11142 * raise.h: (__gnat_set_globals): Change profile.
11144 2006-10-31 Arnaud Charlet <charlet@adacore.com>
11146 * rtsfind.adb: Remove s-polint from comment as it exists no more.
11149 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
11150 Move all the entities in obsolete package System.PolyORB_Interface to
11151 System.Partition_Interface.
11152 (RE_Storage_Size): New function in System.Tasking.
11153 (RE_Get_Ceiling): New entity.

11165 Thomas Quinot <quinot@adacore.com>
11166 Javier Miranda <miranda@adacore.com>
11167 Gary Dismukes <dismukes@adacore.com>
11169 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
11170 properly an attempt to apply Unchecked_Access to a protected operation.
11171 (OK_Self_Reference): New subprogram to check the legality of an access
11172 attribute whose prefix is the type of an enclosing aggregate.
11173 Generalizes previous mechanism to handle attribute references nested
11174 arbitrarily deep within the aggregate.
11175 (Analyze_Access_Attribute): An access attribute whose prefix is a type
11176 can appear in an aggregate if this is a default-initialized aggregate
11177 for a self-referential type.
11178 (Resolve_Attribute, case Access): Ditto.
11179 Add support for new implementation defined attribute Stub_Type.
11180 (Eval_Attribute, case Attribute_Stub_Type): New case.
11181 (Analyze_Attribute, case Attribute_Stub_Type): New case.
11182 (Stream_Attribute_Available): Implement using new subprogram from
11183 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
11184 Has_Specified_Stream_Attribute flag.
11185 Disallow Storage_Size and Storage_Pool for access to subprogram
11186 (Resolve_Attribute, case 'Access et al): Take into account anonymous
11187 access types of return subtypes in extended return statements. Remove
11188 accessibility checks on anonymous access types when Unchecked_Access is
11190 (Analyze_Attribute): Add support for the use of 'Class to convert
11191 a class-wide interface to a tagged type.
11192 Add support for the attribute Priority.
11193 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
11194 whether the designated type is discriminated with a constrained partial
11195 view and require static matching in that case.
11196 Add local variable Des_Btyp. The Designated_Type
11197 of an access to incomplete subtype is either its non-limited view if
11198 coming from a limited with or its etype if regular incomplete subtype.
11200 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
11201 Fix predicate to identify and allow cases of (expander-generated)
11202 references to tag of designated object of a RACW.
11203 (Validate_Static_Object_Name): In Ada 2005, a formal object is
11204 non-static, and therefore cannot appear as a primary in a preelaborable
11206 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
11207 Has_Read_Write_Attributes.
11208 (Has_Read_Write_Attributes): Reimplement in termes of
11209 Has_Stream_Attribute_Definition.
11210 (Missing_Read_Write_Attributes): When checking component types in a
11211 record, unconditionally call Missing_Read_Write_Attributes recursively
11212 (remove guard checking for Is_Record_Type / Is_Access_Type).
11214 2006-10-31 Robert Dewar <dewar@adacore.com>
11216 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
11217 useless assignments here and conditionalize it on absence of exception
11219 (Analyze_Exception_Handlers): Small code reorganization of error
11220 detection code, for new handling of formal packages.
11222 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11223 Hristian Kirtchev <kirtchev@adacore.com>
11225 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
11226 that has been constant-folded, preserve information of original tree,
11228 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
11229 generated private extension declaration if the formal derived type is
11230 synchronized. Carry synchronized present over to the generated private
11232 (Validate_Derived_Type_Instance): Ensure that the actual of a
11233 synchronized formal derived type is a synchronized tagged type.
11234 (Instantiate_Formal_Package): When creating the instantiation used to
11235 validate the actual package of a formal declared without a box, check
11236 whether the formal itself depends on a prior actual.
11237 (Instantiate_Formal_Subprogram): Create new entities for the defining
11238 identifiers of the formals in the renaming declaration, for ASIS use.
11239 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
11240 a renaming declaration or a subtype declaration for an actual in an
11241 instance, capture location information of declaration in generic, for
11243 (Instantiate_Formal_Package): Add comments on needed additional tests.
11244 AI-317 (partial parametrization) is fully implemented.
11245 (Validate_Private_Type_Instance): Add check for actual which
11246 must have preelaborable initialization
11247 Use new // insertion for some continuation messages
11248 (Analyze_Formal_Object_Declaration): Change usage of Expression to
11249 Default_Expression. Add type retrieval when the declaration has an
11250 access definition. Update premature usage of incomplete type check.
11251 (Check_Access_Definition): New subsidiary routine. Check whether the
11252 current compilation version is Ada 05 and the supplied node has an
11254 (Instantiate object): Alphabetize local variables. Handle the creation
11255 of new renaming declarations with respect to the kind of definition
11256 used - either an access definition or a subtype mark. Guard against
11257 unnecessary error message in the context of anonymous access types after
11258 they have been resolved. Add check for required null exclusion in a
11259 formal object declaration.
11260 (Switch_View): A private subtype of a non-private type needs to be
11261 switched (the base type can have been switched without its private
11262 dependents because of the last branch of Check_Private_View.
11263 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
11265 (Instantiate_Type): Emit an error message whenever a class-wide type of
11266 a tagged incomplete type is used as a generic actual.
11267 (Find_Actual_Type): Extend routine to handle a component type in a child
11268 unit that is imported from a formal package in a parent.
11269 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
11270 agree on constrainedness, rather than checking against ultimate ancestor
11271 (Instantiate_Subprogram_Body): Create a cross-reference link to the
11272 generic body, for navigation purposes.
11274 2006-10-31 Robert Dewar <dewar@adacore.com>
11275 Thomas Quinot <quinot@adacore.com>
11277 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
11279 (New_Stream_Subprogram): When processing an attribute definition clause
11280 for a stream-oriented subprogram, record an entity node occurring at
11281 the point of clause to use for checking the visibility of the clause,
11282 as defined by 8.3(23) as amended by AI-195.
11283 (New_Stream_Subprogram): New procedure, factoring behaviour from both
11284 New_Stream_Function and New_Stream_Procedure.
11285 (New_Stream_Function, New_Stream_Procedure): Removed.
11286 (Analyze_Attribute_Definition_Clause, case Address): Check new
11287 Alignment_Check check
11289 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11290 Javier Miranda <miranda@adacore.com>
11291 Robert Dewar <dewar@adacore.com>
11293 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
11294 generate the same errors compiling under -gnatc.
11295 (Try_Object_Operation): If no candidate interpretation succeeds, but
11296 there is at least one primitive operation with the right name, report
11297 error in call rather than on a malformed selected component.
11298 (Analyze_Selected_Component): If the prefix is an incomplete type from
11299 a limited view, and the full view is available, use the full view to
11300 determine whether this is a prefixed call to a primitive operation.
11301 (Operator_Check): Verify that a candidate interpretation is a binary
11302 operation before checking the type of its second formal.
11303 (Analyze_Call): Add additional warnings for function call contexts not
11305 (Analyze_Allocator): Move the check for "initialization not allowed for
11306 limited types" after analyzing the expression. This is necessary,
11307 because OK_For_Limited_Init looks at the structure of the expression.
11308 Before analysis, we don't necessarily know what sort of expression it
11309 is. For example, we don't know whether F(X) is a function call or an
11310 indexed component; the former is legal in Ada 2005; the latter is not.
11311 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
11312 were missing. We also didn't handle qualified expressions. Now also
11313 allow function calls. Use new common routine OK_For_Limited_Init.
11314 (Analyze_Type_Conversion): Do not perform some legality checks in an
11315 instance, because the error message will be redundant or spurious.
11316 (Analyze_Overloaded_Selected_Component): Do not do style check when
11317 setting an entity, since we do not know it is the right entity yet.
11318 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
11319 (Analyze_Overloaded_Selected_Component): Same change
11320 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
11321 since regular incomplete subtypes are transformed into corresponding
11322 subtypes of their full views.
11323 (Complete_Object_Operation): Treat name of transformed subprogram call
11324 as coming from source, for browsing purposes.
11325 (Try_Primitive_Operation): If formal is an access parameter, compare
11326 with base type of object to determine whether it is a primitive
11328 (Operator_Check): If no interpretation of the operator matches, check
11329 whether a use clause on any candidate might make the operation legal.
11330 (Try_Class_Wide_Operation): Check whether the first parameter is an
11331 access type whose designated type is class-wide.
11333 2006-10-31 Robert Dewar <dewar@adacore.com>
11334 Ed Schonberg <schonberg@adacore.com>
11335 Gary Dismukes <dismukes@adacore.com>
11337 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
11338 warn on infinite loops.
11339 Add \\ to some continuation messages
11340 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
11341 (Process_Bounds): If the bounds are integer literals that result from
11342 constant-folding, and they carry a user-defined type, preserve that type
11343 rather than treating this as an integer range.
11344 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
11345 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
11346 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
11347 left hand side of assignment.
11348 (Analyze_Assignment): Add suport to manage assigments to the attribute
11349 priority of a protected object.
11350 (Check_Possible_Current_Value_Condition): Allow fully qualified names
11351 not just identifiers.
11352 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
11353 or AND THEN for possible tracking.
11354 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
11355 case of while loops so we can track values in the loop body.
11357 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11358 Hristian Kirtchev <kirtchev@adacore.com>
11359 Bob Duff <duff@adacore.com>
11361 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
11362 procedure cannot be a protected operation (it is a basic_declaration,
11363 not a subprogram_declaration).
11364 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
11365 Subp. Add logic for entry processing.
11366 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
11367 Determine whether an entry or subprogram of a protected or task type
11368 override an inherited primitive of an implemented interface.
11369 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
11370 Update the actual used in calls to Check_Overriding_Indicator.
11371 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
11372 generate the proper reference to the parent unit, for cross-reference.
11373 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
11375 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
11376 (Add_Extra_Formal): Revise procedure to allow passing in associated
11377 entity, scope, and name suffix, and handle setting of the new
11378 Extra_Formals field.
11379 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
11380 pass new parameters. Add support for adding the new extra access formal
11381 for functions whose calls are treated as build-in-place.
11382 (Analyze_A_Return_Statement): Correct casing in error message.
11383 Move Pop_Scope to after Analyze_Function_Return, because an extended
11384 return statement really is a full-fledged scope. Otherwise, visibility
11385 doesn't work right. Correct use of "\" for continuation messages.
11386 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
11387 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
11388 the node doesn't get properly marked as analyzed.
11389 (Analyze_Subprogram_Body): If subprogram is a function that returns
11390 an anonymous access type that denotes a task, build a Master Entity
11392 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
11393 proper usage of null exclusion in a result definition.

11421 package, install private_with_clauses of enclosing compilation unit if
11422 we are in its visible part.
11423 (Declare_Inherited_Private_Subprograms): Complete barrier
11424 to ensure that the primitive operation has an alias to some parent
11425 primitive. This is now required because, after the changes done for the
11426 implementation of abstract interfaces, the contents of the list of
11427 primitives has entities whose alias attribute references entities of
11428 such list of primitives.
11429 (Analyze_Package_Specification): Simplify code that handles parent units
11430 of instances and formal packages.

11446 as potentially use-visible.
11447 (Find_Type): Handle the case of an attribute reference for
11448 implementation defined attribute Stub_Type (simply let the analysis of

11463 their counterparts of the renaming already impose them.
11464 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
11465 Determine whether an entity is inside a generic scope.
11466 (In_Open_Scope): First pass of documentation update.

11468 limited withed packages. This is required to handle nested packages.
11469 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
11470 that makes a renaming of a limited withed package illegal.

11476 Check_Overriding_Indicator.
11477 (Analyze_Task_Definition): Ditto.
11478 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
11479 (Check_Overriding_Indicator): To find overridden interface operation,
11480 examine only homonyms that have an explicit subprogram declaration, not
11481 inherited operations created by an unrelated type derivation.
11482 (Check_Overriding_Indicator): When checking for the presence of "null"
11483 in a procedure, ensure that the queried node is a procedure

11501 of a call to a function that dispatches on access result.
11502 (Check_Dispatching_Operation): In case of late overriding of a primitive
11503 that covers abstract interface subprograms we register it in all the
11504 secondary dispatch tables associated with abstract interfaces.
11505 (Check_Dispatching_Call): Add check that a dispatching call is not made
11506 to a function with a controlling result of a limited type. This is a
11507 current implementation restriction.
11508 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
11509 (Check_Dispatching_Operation): Do no emit a warning if the controlling

11512 (Check_Dispatching_Operation): If the subprogram is not a dispatching
11513 operation, check the formals to handle the case in which it is
11514 associated with an abstract interface type.

11557 ought to be used, but we currently only deal properly with zero or one
11559 (In_Instance); The analysis of the actuals in the instantiation of a
11560 child unit is not within an instantiation, even though the parent
11561 instance is on the scope stack.

11564 (Check_Obsolescent): Removed
11565 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

11820 This is a significant redesign primarily for the sake of automatic
11821 timer task termination but also to fix a design flaw.
11822 Therefore we are now using an RTS lock, instead of a protected
11823 object, to provide mutual exclusion to the queue of pending events
11824 and the type Timing_Event is no longer a protected type.

12672 other basic tools. The full version that includes the Ada 2005 stuff
12673 is in separate files a-except-2005.ads/adb. The reason is that we do
12674 not want to cause bootstrap problems with compilers not recognizing
12676 Add exception reason code PE_Implicit_Return

12998 -d is now controlling the primary stack size when its value is a
12999 positive. Also add checks against invalid values, and support for kb,
13000 mb. Ditto for -D switch.

13003 Serguei Rybin <rybin@adacore.com>
13005 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
13006 save/restore routines.
13007 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

13009 Since we are changing the tree format anyway, also get rid of the
13010 junk obsolete Immediate_Errors flag.
13011 (Tree_Read): Change the way of reading Tree_Version_String - now we
13012 read the version string from the tree even if its length is not the
13013 same as the length of the version string computed from Gnatvsn.
13014 (Search_Directory_Present): New Boolean flag for the compiler.
13015 Define Tree_Version_String as a dynamic string.

13036 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
13037 (Is_Known_Null): New flag
13038 (Has_Pragma_Pure): New flag

13040 (Is_Limited_Type): A type whose ancestor is an interface is limited if
13041 explicitly declared limited.
13042 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
13043 entities. Only used for component marked Is_Tag. If present it stores
13044 the Offset_To_Top function used to provide this value in tagged types
13045 whose ancestor has discriminants.
13047 * exp_ch2.adb: Update status of new Is_Known_Null flag
13049 * sem_ch7.adb: Maintain status of new Is_Known_Null flag

13068 (__gl_default_stack_size): new variable.
13070 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13072 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
13073 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
13074 does not exist in the Ada RM.
13075 (Compatible_Int_Bounds): Determine whether two integer range bounds
13076 are of equal length and have the same start and end values.
13077 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
13078 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
13079 aggregate when it is part of an object declaration.
13080 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
13081 constrains discriminants of its parent, add explicitly the discriminant
13082 constraints of the ancestor by retrieving them from the
13083 stored_constraint of the parent.
13085 2006-02-13 Robert Dewar <dewar@adacore.com>
13087 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
13088 attribute Mechanism_Code is applied to renamed subprogram, modify
13089 prefix to point to base subprogram.
13090 Max/Min attributes now violate Restriction No_Implicit_Conditionals
13092 * sinfo.ads: Document that Mechanism_Code cannot be applied to
13093 renamed subprograms so that the front-end must replace the prefix

13097 Gary Dismukes <dismukes@adacore.com>
13099 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
13100 availability of RE_Interface_Tag.
13101 (Build_Initialization_Call): Fix wrong access to the discriminant value.
13102 (Freeze_Record_Type): Do not generate the tables associated with
13103 timed and conditional dispatching calls through synchronized
13104 interfaces if compiling under No_Dispatching_Calls restriction.
13105 When compiling for Ada 2005, for a nonabstract
13106 type with a null extension, call Make_Controlling_Function_Wrappers
13107 and insert the wrapper function declarations and bodies (the latter
13108 being appended as freeze actions).
13109 (Predefined_Primitive_Bodies): Do not generate the bodies of the
13110 predefined primitives associated with timed and conditional
13111 dispatching calls through synchronized interfaces if we are
13112 compiling under No_Dispatching_Calls.
13113 (Build_Init_Procedure): Use RTE_Available to check if a run-time
13114 service is available before generating a call.
13115 (Make_Controlling_Function_Wrappers): New procedure.
13116 (Expand_N_Full_Type_Declaration): Create a class-wide master for
13117 access-to-limited-interfaces because they can be used to reference
13118 tasks that implement such limited interface.
13119 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
13120 procedure spec and body of the Offset_To_Top function that is generated
13121 when the parent of a type with discriminants has secondary dispatch
13123 (Init_Secondary_Tags): Handle the case in which the parent of the type
13124 containing secondary dispatch tables has discriminants to generate the
13125 correct arguments to call Set_Offset_To_Top.
13126 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
13128 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
13129 Add Wide_[Wide_]Expanded_Name.
13130 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
13131 the same functionality of Get_Prim_Op_Address but applied to predefined
13132 primitive operations because the pointers to the predefined primitives
13133 are now saved in a separate table.
13134 (Parent_Size): Modified to get access to the separate table of primitive
13135 operations or the parent type.
13136 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
13137 functionality of Set_Prim_Op_Address but applied to predefined primitive
13139 (Set_Signature): New subprogram used to store the signature of a DT.
13140 (Displace): If the Offset_To_Top value is not static then call the
13141 function generated by the expander to get such value; otherwise use
13142 the value stored in the table of interfaces.
13143 (Offset_To_Top): The type of the actual has been changed to Address to
13144 give the correct support to tagged types with discriminants. In this
13145 case this value is stored just immediately after the tag field.
13146 (Set_Offset_To_Top): Two new formals have been added to indicate if the
13147 offset_to_top value is static and hence pass this value to the run-time
13148 to store it in the table of interfaces, or else if this value is dynamic
13149 and then pass to the run-time the address of a function that is
13150 generated by the expander to provide this value for each object of the
13153 * rtsfind.ads (Default_Prin_Op_Count): Removed.
13154 (Default_Prim_Op_Count): New entity
13155 (Get_Predefined_Prim_Op_Address): New entity

13160 Ed Schonberg <schonberg@adacore.com>
13162 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
13163 Make_Adjust_Call done for a newly-allocated object.
13165 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
13166 in a subprogram are wrapped in a cleanup block, indicate that the
13167 subprogram contains an inner block with an exception handler.
13168 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
13169 Adjust call is for a newly-allocated object. In that case we must not
13170 assume that the finalization list chain pointers are correct (since they
13171 come from a bit-for-bit copy of the original object's pointers) so if
13172 the attach level would otherwise be zero (no change), we set it to 4
13173 instead to cause the pointers to be reset to null.
13175 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
13176 reset chain pointers to null.
13178 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13180 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
13181 string, and the context requires a loop for the assignment (e.g.
13182 because the left-hand side is packed), generate a unique name for the
13183 temporary that holds the string, to prevent spurious name clashes.
13185 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13186 Javier Miranda <miranda@adacore.com>
13187 Robert Dewar <dewar@adacore.com>
13188 Gary Dismukes <dismukes@adacore.com>
13190 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
13191 return unconstrained arrays.
13193 (Expand_Call): An indirect call through an access parameter of a
13194 protected operation is not a protected call.
13195 Add circuit to raise CE in Ada 2005 mode following call
13196 to Raise_Exception.
13197 (Register_DT_Entry): Do nothing if
13198 the run-time does not give support to abstract interfaces.
13199 (Freeze_Subprogram): In case of dispatching operations, do not generate
13200 code to register the operation in the dispatch table if the source
13201 is compiled with No_Dispatching_Calls.
13202 (Register_Predefined_DT_Entry): Generate code that calls the new
13203 run-time subprogram Set_Predefined_Prim_Op_Address instead of
13204 Set_Prim_Op_Address.
13206 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
13207 on array assignments if the right-hand side is a function call that has
13208 been inlined. Check is performed on the assignment in the block.
13209 (Process_Bounds): If bounds and range are overloaded, apply preference
13210 rule for root operations to disambiguate, and diagnose true ambiguity.
13211 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
13212 a tag-indeterminate right-hand side even when Expander_Active is True.
13213 Needed to ensure that dispatching calls to T'Input are allowed and
13214 get the tag of the target class-wide object.
13216 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
13217 an inherited primitive operation that already overrides several
13218 abstract interface primitives. For transitivity, the new entity must
13219 also override all the abstract interface primitives covered by the
13220 inherited overriden primitive.
13221 Emit warning if new entity differs from homograph in same scope only in
13222 that one has an access parameter and the other one has a parameter of
13223 a general access type with the same designated type, at the same
13224 position in the signature.
13225 (Make_Inequality_Operator): Use source locations of parameters and
13226 subtype marks from corresponding equality operator when creating the
13227 tree structure for the implicit declaration of "/=". This does not
13228 change anything in behaviour except that the decoration of the
13229 components of the subtree created for "/=" allows ASIS to get the
13230 string images of the corresponding identifiers.
13231 (Analyze_Return_Statement): Remove '!' in warning message.
13232 (Check_Statement_Sequence): Likewise.
13233 (Analyze_Subprogram_Body): For an access parameter whose designated type
13234 is an incomplete type imported through a limited_with clause, use the
13235 type of the corresponding formal in the body.
13236 (Check_Returns): Implicit return in No_Return procedure now raises
13237 Program_Error with a compile time warning, instead of beging illegal.
13238 (Has_Single_Return): Function returning unconstrained type cannot be
13239 inlined if expression in unique return statement is not an identifier.
13240 (Build_Body_To_Inline): It is possible to inline a function call that
13241 returns an unconstrained type if all return statements in the function
13242 return the same local variable. Subsidiary procedure Has_Single_Return
13243 verifies that the body conforms to this restriction.
13245 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
13246 same type, and one of them is of an anonymous access type, convert
13247 the other operand to it, so that this is a valid binary operation for
13249 (Resolve_Type_Conversion): Handle subtypes of protected types and
13250 task types when accessing to the corresponding record type.
13251 (Resolve_Allocator): Add '\' in 2-line warning message.
13252 Remove '!' in warning message.
13253 (Resolve_Call): Add '\' in 2-line warning message.
13254 (Valid_Conversion): Likewise.
13255 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
13256 resulting type may be an access type with an implicit dereference.
13257 Obtain the proper component from the designated type.
13258 (Make_Call_Into_Operator): Handle properly a call to predefined equality
13259 given by an expanded name with prefix Standard, when the operands are
13260 of an anonymous access type.
13261 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
13262 Explicit_Dereference and Resolve_Selected_Component, to verify that the
13263 prefix of the expression is not of an incomplete type. Allows full
13264 diagnoses of all semantic errors.
13265 (Resolve_Actuals): If the actual is an allocator whose directly
13266 designated type is a class-wide interface we build an anonymous
13267 access type to use it as the type of the allocator. Later, when
13268 the subprogram call is expanded, if the interface has a secondary
13269 dispatch table the expander will add a type conversion to force
13270 the displacement of the pointer.
13271 (Resolve_Call): If a function that returns an unconstrained type is
13272 marked Inlined_Always and inlined, the call will be inlined and does
13273 not require the creation of a transient scope.
13274 (Check_Direct_Boolean_Op): Removed
13275 (Resolve_Comparison_Op): Remove call to above
13276 (Resolve_Equality_Op): Remove call to above
13277 (Resolve_Logical_Op): Inline above, since this is only call.
13278 (Valid_Conversion): Handle properly conversions between arrays of
13279 convertible anonymous access types.
13282 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
13283 the literal in an unchecked conversion, because GCC 4.x needs a static
13284 value for a string bound.
13286 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13287 Hristian Kirtchev <kirtchev@adacore.com>
13289 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
13290 components of the corresponding record, take into account component
13291 definitions that are access definitions.
13292 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
13293 procedure is not considered a dispatching call and will be expanded
13296 2006-02-13 Javier Miranda <miranda@adacore.com>
13298 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
13299 controlling argument of the dispatching call is an abstract interface
13300 class-wide type then we use it directly.
13301 Check No_Dispatching_Calls restriction.
13302 (Default_Prim_Op_Position): Remove the code that looks for the last
13303 entity in the list of aliased subprograms. This code was wrong in
13305 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
13306 when the source is compiled with the No_Dispatching_Calls restriction.
13307 (Init_Predefined_Interface_Primitives): No need to inherit primitives
13308 if we are compiling with restriction No_Dispatching_Calls.
13309 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
13310 subprograms if we are compiling under No_Dispatching_Calls restriction.
13311 (Make_DT): Generate a dispatch table with a single dummy entry if
13312 we are compiling with the No_Dispatching_Calls restriction. In
13313 addition, in this case we don't generate code that calls to the
13314 following run-time subprograms: Set_Type_Kind, Inherit_DT.
13315 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
13316 of this subprogram if compiling with the No_Dispatching_Calls
13318 (Expand_Type_Conversion): Instead of using the actual parameter,
13319 the argument passed as parameter to the conversion function was
13320 erroneously referenced by the expander.
13321 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
13322 Set_Predefined_Primitive_Op_Address and Set_Signature.
13323 (Expand_Dispatching_Call): Generate call to
13324 Get_Predefined_Prim_Op_Address for predefined primitives.
13325 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
13326 predefined primitives.
13327 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
13328 primitives we reserve one dummy entry to ensure that the tag does not
13329 point to some memory that is associated with some other object. In
13330 addition, remove all the old code that generated the assignments
13331 associated with the signature of the dispatch table and replace them
13332 by a call to the new subprogram Set_Signature.
13333 (Set_All_DT_Position): Change the algorithm because now we have a
13334 separate dispatch table associated with predefined primitive operations.
13335 (Expand_Interface_Conversion): In case of non-static offset_to_top
13336 add explicit dereference to get access to the object after the call
13337 to displace the pointer to the object.
13338 (Expand_Interface_Thunk): Modify the generation of the actual used
13339 in the calls to the run-time function Offset_To_Top to fulfil its
13341 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.

13345 * exp_dist.adb (Copy_Specification): For access parameters, copy
13346 Null_Exclusion flag, which will have been set for stream subprograms
13349 2006-02-13 Pascal Obry <obry@adacore.com>
13351 * expect.c (__gnat_expect_portable_execvp): New implementation. The
13352 previous implementation was using the C runtime spawnve routine but
13353 the corresponding wait was using directly the Win32 API. This was
13354 causing some times a lock when waiting for an event using
13355 WaitForSingleObject in __gnat_waitpid. This new implementation uses
13356 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
13357 API fixes this problem.
13359 2006-02-13 Robert Dewar <dewar@adacore.com>
13361 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

13369 array reference that is an explicit dereference, mark the converted
13370 (packed) array reference as analyzed to prevent a forthcoming
13371 reanalysis from resetting its type to the original (non-packed) array
13374 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13375 Javier Miranda <miranda@adacore.com>
13376 Eric Botcazou <ebotcazou@adacore.com>
13378 * exp_util.ads, exp_util.adb (Find_Prim_Op,
13379 Is_Predefined_Primitive_Operation): When
13380 searching for the predefined equality operator, verify that operands
13381 have the same type.
13382 (Is_Predefined_Dispatching_Operation): Remove the code that looks
13383 for the last entity in the list of aliased subprograms. This code
13384 was wrong in case of renamings.
13385 (Set_Renamed_Subprogram): New procedure
13386 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
13387 Exp_Type constant computed when entering this subprogram.

13389 (OK_To_Do_Constant_Replacement): New function
13390 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
13391 (Side_Effect_Free): An attribute reference 'Input is not free of
13392 side effect, unlike other attributes that are functions. (from code
13394 (Remove_Side_Effects): Expressions that involve packed arrays or records
13395 are copied at the point of reference, and therefore must be marked as
13396 renamings of objects.
13397 (Is_Predefined_Dispatching_Operation): Return false if the operation is
13398 not a dispatching operation.
13401 (Remove_Side_Effects): Lift enclosing type conversion nodes for
13402 elementary types in all cases.
13404 2006-02-13 Javier Miranda <miranda@adacore.com>

13407 task types when accessing to the corresponding record type.
13408 Remove '!' in warning message.
13410 2006-02-13 Olivier Hainque <hainque@adacore.com>
13412 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
13413 to avoid useless and space inefficient overalignments on targets where
13414 Max_Alignment is larger than 16.
13416 2006-02-13 Pascal Obry <obry@adacore.com>
13418 * g-catiio.adb (Sec_Number): New type used to compute the number of
13419 seconds since 1-1-1970.
13420 (Image) [Natural]: The parameter was an Integer, as we can't deal with
13421 negative numbers (years, months...) it is better to have a Natural here.
13423 (Image) [Number]: Change parameter from Long_Integer to Number.
13424 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
13425 overflow for dates past year 2038.
13427 2006-02-13 Matthew Heaney <heaney@adacore.com>
13429 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
13432 2006-02-13 Arnaud Charlet <charlet@adacore.com>
13434 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
13436 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
13437 finalization can occur normally.
13439 2006-02-13 Vincent Celier <celier@adacore.com>
13441 * gnatcmd.adb (Rules_Switches): New table
13442 (Add_To_Rules_Switches): New procedure
13443 (GNATCmd): For command CHECK, put all options following "-rules" in the
13444 Rules_Switches table. Append these -rules switches after the -cargs
13447 2006-02-13 Robert Dewar <dewar@adacore.com>
13449 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
13450 These two cases were generating incorrect output, and if this unit
13451 was built with checks on, generated a discriminant mismatch constraint
13454 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13455 Robert Dewar <dewar@adacore.com>
13457 * lib-xref.adb (Get_Type_Reference): For a private type whose full
13458 view is an array type, indicate the component type as well, for
13459 navigation purposes.
13460 (Generate_Reference): Don't consider array ref on LHS to be a case
13461 of violating pragma Unreferenced.
13462 Do not give Ada 2005 warning except on real reference.
13464 2006-02-13 Vincent Celier <celier@adacore.com>
13466 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
13467 main source, add switch -mdebug-main=_ada_ so that the executable can
13468 be debugged by the standard VMS debugger.
13469 (Gnatmake): Set No_Main_Subprogram to True when there is no main
13470 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
13471 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
13472 of the last source, as the binding and linking phases are never
13474 Set all executable obsolete when rebuilding a library.
13476 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
13479 2006-02-13 Javier Miranda <miranda@adacore.com>
13482 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
13483 code to improve the error message reported when the program has
13484 declarations of abstract interface types and it is not compiled with
13485 the -gnat05 switch.
13486 (P_Access_Definition): Reorganize the code to improve the error
13487 message reported when the new Ada 2005 syntax for anonymous
13488 access types is used and the program is not compiled with the

13504 * prj.adb (Reset): Initialize the first element of table Namings with
13505 the standard naming data.
13507 2006-02-13 Vincent Celier <celier@adacore.com>
13509 * prj.ads (Error_Warning): New enumeration type
13511 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
13512 unknown, use the location of the project to report the error.
13513 (When_No_Sources): New global variable
13514 (Report_No_Ada_Sources): New procedure
13515 (Check): New parameter When_No_Sources. Set value of global variable
13517 (Find_Sources): Call Report_No_Ada_Sources when appropriate
13518 (Get_Sources_From_File): Ditto
13519 (Warn_If_Not_Sources): Better warning messages indicating the unit name
13522 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
13523 Call Prj.Proc.Process with parameter When_No_Sources.
13525 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
13526 Call Recursive_Check with parameter When_No_Sources.
13527 (Recursive_Check): New parameter When_No_Sources. Call itself and
13528 Prj.Nmsc.Check with parameter When_No_Sources.
13529 (Process): New parameter When_No_Sources. Call Check with parameter
13531 (Copy_Package_Declarations): New procedure to copy renamed parameters
13532 and setting the location of the declared attributes to the location
13533 of the renamed package.

13541 When removing nodes (attributes Source_Dirs, Source_Files,
13542 Source_List_File and package Naming), save the comments and attach the
13543 saved comments to the newly created nodes.
13544 Do not add a with clause for the naming package if one already exists.

13552 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
13553 aliased entities to look for the overriden abstract interface
13555 (Is_Interface_Subprogram): Complete documentation.
13556 (Check_Dispatching_Operation): Do not generate code to register the
13557 operation in the dispatch table if the source is compiled with
13558 restriction No_Dispatching_Calls.

13560 No_Return procedure with procedure that is not No_Return
13561 (Check_Dispatching_Call): Suppress the check for an abstract operation
13562 when the original node of an actual is a tag-indeterminate attribute
13563 call, since the attribute, which must be 'Input, can never be abstract.
13564 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
13565 call to the Input attribute (even when rewritten).
13566 (Propagate_Tag): Augment comment to indicate the possibility of a call
13567 to an Input attribute.
13569 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
13570 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
13572 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
13573 No_Wide_Characters is no longer partition-wide
13574 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)

13579 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
13581 2006-02-13 Javier Miranda <miranda@adacore.com>
13583 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
13584 handles default-initialized components to keep separate the management
13585 of this feature but also avoid the unrequired resolution and
13586 expansion of components that do not have partially initialized
13588 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
13589 (Check_Bounds): Likewise.
13590 (Check_Length): Likewise.
13592 2006-02-13 Javier Miranda <miranda@adacore.com>
13593 Ed Schonberg <schonberg@adacore.com>
13595 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
13596 abstract interface type call analyze_and_resolve to expand the type
13597 conversion into the corresponding displacement of the
13598 reference to the base of the object.
13599 (Eval_Attribute, case Width): For systems where IEEE extended precision
13600 is supported, the maximum exponent occupies 4 decimal digits.
13601 (Accessibility_Message): Add '\' in 2-line warning message.
13602 (Resolve_Attribute): Likewise.
13603 (case Attribute_Access): Significantly revise checks
13604 for illegal access-to-subprogram Access attributes to properly enforce
13605 the rules of 3.10.2(32/2).
13606 Diagnose use of current instance with an illegal attribute.
13608 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
13610 (Enclosing_Generic_Unit): New function to return a node's innermost
13611 enclosing generic declaration node.
13612 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
13613 (Type_Access_Level): The accessibility level of anonymous acccess types
13614 associated with discriminants is that of the current instance of the
13615 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
13616 (Compile_Time_Constraint_Error): Handle case of conditional expression.
13617 (Kill_Current_Values_For_Entity): New function
13618 (Enter_Name): Change formal type to Entity_Id
13620 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
13621 Ed Schonberg <schonberg@adacore.com>
13622 Gary Dismukes <dismukes@adacore.com>
13624 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
13625 Analyze_Compilation_Unit.
13626 Detect and warn on redundant with clauses detected in a package spec
13627 and/or body when -gnatwr is used.

13631 with_clause so that cross-reference information or warning messages on
13632 unused packages can be properly generated
13633 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
13634 has Error_Posted set. Prevent infinite loops in illegal programs.
13635 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
13636 to the point of the error test requiring the current unit to be private.
13637 This ensures that private with clauses are not exempted from the basic
13638 checking for being a descendant of the same library unit parent as a
13639 withed private descendant unit.
13640 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
13641 handle private with clauses properly, as well as to account for cases
13642 where the withed unit is a public descendant of a private ancestor
13643 (in which case the current unit must be a descendant of the private
13644 ancestor's parent). The spec comments were updated accordingly. Also,
13645 the old error message in this subprogram was replaced with error
13646 messages that mirror the errors tested and reported by
13647 Check_Private_Child_Unit.
13648 Parameter and variable names improved for readability.
13649 (Install_Limited_Context_Clauses): Remove test for a withed unit being
13650 private as the precondition for calling
13651 Check_Private_Limited_Withed_Unit since that subprogram has been
13652 revised to test public units as well as private units.

13659 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
13660 that Scope_Stack.First = 1.
13661 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
13662 were not always properly handled previously.
13663 (Formal_Entity): Complete rewrite, to handle properly some complex case
13664 with multiple levels of parametrization by formal packages.
13665 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
13666 to the corresponding derived type declaration for proper semantics.
13668 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
13669 (Check_Component): Enforce restriction on components of
13670 unchecked_unions: a component in a variant cannot contain tasks or
13672 (Unchecked_Union): Allow nested variants and multiple discriminants, to
13674 Add pragma Ada_2005 (synonym for Ada_05)
13675 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
13676 were not always properly handled previously.
13677 Document that pragma Propagate_Exceptions has no effect
13678 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
13679 (Set_Convention_From_Pragma): Check that if a convention is
13680 specified for a dispatching operation, then it must be
13681 consistent with the existing convention for the operation.
13682 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
13683 longer required to specify an vtable-ptr component in the record. For
13684 compatibility reasons we leave the support for the previous definition.
13685 (Analyze_Pragma, case No_Return): Allow multiple arguments
13687 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
13688 non-overrideen inherited operation with a controlling result as
13689 illegal only its implicit declaration comes from the derived type
13690 declaration of its result's type.
13691 (Check_Possible_Deferred_Completion): Relocate the object definition
13692 node of the subtype indication of a deferred constant completion rather
13693 than directly analyzing it. The analysis of the generated subtype will
13694 correctly decorate the GNAT tree.
13695 (Record_Type_Declaration): Check whether this is a declaration for a
13696 limited derived record before analyzing components.
13697 (Analyze_Component_Declaration): Diagnose record types not explicitly
13698 declared limited when a component has a limited type.
13699 (Build_Derived_Record_Type): Code reorganization to check if some of
13700 the inherited subprograms of a tagged type cover interface primitives.
13701 This check was missing in case of a full-type associated with a private
13703 (Constant_Redeclaration): Check that the subtypes of the partial and the
13704 full view of a constrained deferred constant statically match.
13705 (Mentions_T): A reference to the current type in an anonymous access
13706 component declaration must be an entity name.
13707 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
13708 class_wide type to refer to full type, not to the incomplete one.
13709 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
13710 available. Required to give support to the certified run-time.
13711 (Analyze_Component_Declaration): In case of anonymous access components
13712 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
13713 (Process_Discriminants): For an access discriminant, use the
13714 discriminant specification as the associated_node_for_itype, to
13715 simplify accessibility checks.

13718 Javier Miranda <miranda@adacore.com>
13720 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
13721 abstract interpretations on an operator, remove interpretations that
13722 yield Address or a type derived from it, if one of the operands is an
13724 (Try_Object_Operation.Try_Primitive_Operation,
13725 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
13726 location when creating the new reference to a primitive or class-wide
13727 operation as a part of rewriting a subprogram call.
13728 (Try_Primitive_Operations): If context requires a function, collect all
13729 interpretations after the first match, because there may be primitive
13730 operations of the same type with the same profile and different return
13731 types. From code reading.
13732 (Try_Primitive_Operation): Use the node kind to choose the proper
13733 operation when a function and a procedure have the same parameter
13735 (Complete_Object_Operation): If formal is an access parameter and prefix
13736 is an object, rewrite as an Access reference, to match signature of
13737 primitive operation.
13738 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
13739 by an expanded name with prefix Standard, when the operands are of an
13740 anonymous access type.
13741 (Remove_Abstract_Operations): If the operation is abstract because it is
13742 inherited by a user-defined type derived from Address, remove it as
13743 well from the set of candidate interpretations of an overloaded node.
13744 (Analyze_Membership_Op): Membership test not applicable to cpp-class
13747 2006-02-13 Bob Duff <duff@adacore.com>
13749 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
13750 redundant use clauses.
13751 In particular, if the scope of two use clauses overlaps, but one is not
13752 entirely included in the other, we should not warn. This can happen
13753 with nested packages.
13754 (Analyze_Subprogram_Renaming): Protect the compiler against previously
13755 reported errors. The bug was reported when the compiler was built
13756 with assertions enabled.
13757 (Find_Type): If the node is a 'Class reference and the prefix is a
13758 synchronized type without a corresponding record, return the type
13761 2006-02-13 Javier Miranda <miranda@adacore.com>
13763 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
13764 if this is the full-declaration associated with a private declaration
13765 that implement interfaces, then the private type declaration must be
13767 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
13768 as aliased. The use of the 'access attribute is not available for such
13769 object (for this purpose the object should be explicitly marked as
13770 aliased, but being an anonymous type this is not possible).
13772 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13773 Robert Dewar <dewar@adacore.com>
13775 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
13776 compilation unit is an elaboration scope.
13777 (Add_Task_Proc): Add '\' in 2-line warning message.
13778 (Activate_All_Desirable): Deal with case of unit with'ed by parent
13780 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13781 Javier Miranda <miranda@adacore.com>
13783 * sem_type.adb (Write_Overloads): Improve display of candidate
13785 (Add_One_Interp): Do not add to the list of interpretations aliased
13786 entities corresponding with an abstract interface type that is an
13787 immediate ancestor of a tagged type; otherwise we have a dummy
13788 conflict between this entity and the aliased entity.
13789 (Disambiguate): The predefined equality on universal_access is not
13790 usable if there is a user-defined equality with the proper signature,
13791 declared in the same declarative part as the designated type.
13792 (Find_Unique_Type): The universal_access equality operator defined under
13793 AI-230 does not cover pool specific access types.
13794 (Covers): If one of the types is a generic actual subtype, check whether
13795 it matches the partial view of the other type.
13797 2006-02-13 Thomas Quinot <quinot@adacore.com>
13799 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
13800 line. This is necessary to allow In_Extended_Main_Unit to provide
13801 correct results for itypes while writing out expanded source.
13802 (Close_File): No need to update the source_index_table here since it's
13803 now done for each line.
13805 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13806 Robert Dewar <dewar@adacore.com>
13808 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
13809 preserve the source unit where the itype is declared, and prevent a

13819 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
13822 2006-02-13 Bob Duff <duff@adacore.com>
13824 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
13825 Scan_Unsigned, so we do not scan leading blanks and sign twice.
13826 Integer'Value("- 5") and Integer'Value("-+5") now correctly
13827 raise Constraint_Error.
13829 * s-vallli.adb (Scan_Long_Long_Integer): Call
13830 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
13831 do not scan leading blanks and sign twice.
13832 Integer'Value("- 5") and Integer'Value("-+5") now correctly
13833 raise Constraint_Error.
13835 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
13836 Scan_Long_Long_Unsigned): Split out most of the processing from
13837 Scan_Long_Long_Unsigned out into
13838 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
13839 This prevents scanning leading blanks and sign twice.
13840 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
13843 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
13844 out most of the processing from Scan_Unsigned out into
13845 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
13846 This prevents scanning leading blanks and sign twice.
13848 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
13849 use with Modular'Value attribute.
13850 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
13853 2006-02-13 Robert Dewar <dewar@adacore.com>
13855 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value

14046 Florian Villoing <villoing@adacore.com>
14048 * a-taster.ads, a-taster.adb: New files.
14050 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
14051 link to the version that does nothing. This way the task termination
14052 routine is not executed twice for the environment task when finishing
14053 because of an unhandled exception.
14055 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
14056 handler because of an unhandled exception.
14058 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
14059 System.Tasking.Utilities instead of that in System.Tasking.Stages.
14061 * s-finimp.adb (initialization code): Modify the soft link for the
14062 finalization of the global list instead of Adafinal.
14064 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
14065 non-tasking version of the soft link for task termination. We do
14066 nothing since if we are using the non-tasking version it
14067 means that the task termination functionality is not used.
14068 (Null_Finalize_Global_List): Add this null version for the procedure
14069 in charge of finalizing the global list for controlled objects.
14070 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
14071 instead for handling run-time termination in a more flexible way.
14072 (Adafinal_NT): This new procedure will take care of finalizing the
14073 global list for controlled objects if needed, but no tasking
14076 * s-tarest.adb (Task_Lock): Do not try to lock again the
14077 Global_Task_Lock if we already own it. Otherwise, we get blocked in
14078 some run-time operations.
14079 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
14080 until all nested locks have been released.
14081 (Task_Wrapper): Call the fall-back task termination handler. It
14082 applies to all tasks but the environment task.
14083 (Finalize_Global_Tasks): Add the call for the task termination
14084 procedure for the environment task.
14085 (Task_Wrapper): suppress warnings around declaration of
14086 Secondary_Stack_Address.
14088 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
14089 moved to the Common_ATCB record.
14090 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
14091 Common_ATCB record.
14092 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
14093 Common_ATCB record.
14095 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
14096 Fall_Back_Handler, and Specific_Handler.
14098 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
14099 defined in Ada.Task_Termination, to avoid circular dependencies.
14100 (Termination_Handler): Redefine this type here, alredy defined in
14101 Ada.Task_Termination, for avoiding circular dependencies.
14102 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
14103 for storing task termination handlers. In addition,
14104 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
14105 Common_ATCB because it is used by both the regular and the restricted
14107 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
14108 Common_ATCB because it is used by both the regular and the restricted
14110 (Common_ATCB): Added a dynamic task analyzer field.
14112 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
14113 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
14114 (Task_Wrapper): Call the task termination handler. It applies to all
14115 tasks but the environment task.
14116 (Finalize_Global_Tasks): Call the task termination procedure for the
14117 environment task. The call to Finalize_Global_List is now performed
14118 using the soft links mechanism.
14119 (Task_Wrapper): added dynamic stack analysis.
14121 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
14122 potentially blocking operations has been moved from
14123 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
14124 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
14125 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
14126 this run-time check.
14128 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
14129 of task termination procedure.
14130 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
14131 link for the task termination procedure.
14133 * bindusg.adb: (Bindusg): Added documentation for -u option.

14143 * opt.ads: Added flags used by dynamic stack measurement.
14144 (Max_Line_Length): Remove (not used anymore)
14146 * s-io.ads, s-io.adb (Standard_Error): new subprogram
14147 (Standart_Output): new subprogram
14148 (Set_Output): new subprogram
14149 (Put): now uses the value of Current_Out to know if the output has to be
14150 send to stderr or stdout.
14152 * s-stausa.ads: Complete implementation.
14154 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
14156 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
14157 list of Ada 05 files.
14158 (GNAT Library Units): Add AltiVec files.
14160 * g-allein.ads, g-alleve.adb, g-alleve.ads, g-altcon.adb,
14161 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
14162 g-alvety.ads, g-alvevi.ads: New files providing altivec API.
14164 2005-12-09 Nicolas Setton <setton@adacore.com>
14166 * adaint.c (__gnat_locate_regular_file): Return immediately if
14167 file_name is empty.
14169 2005-12-09 Javier Miranda <miranda@adacore.com>
14170 Hristian Kirtchev <kirtchev@adacore.com>
14172 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
14173 to the specification because the frontend generates code that uses this
14175 (Set_Interface_Table): Add missing assertion.
14176 Update documentation describing the run-time structure.
14177 (Displace): New subprogram that displaces the pointer to the object
14178 to reference one of its secondary dispatch tables.
14179 (IW_Membership): Modified to use the new table of interfaces.
14180 (Inherit_TSD): Modified to use the new table of interfaces.
14181 (Register_Interface_Tag): Use the additional formal to fill the
14182 contents of the new table of interfaces.
14183 (Set_Interface_Table): New subprogram that stores in the TSD the
14184 pointer to the table of interfaces.
14185 (Set_Offset_To_Top): Use the additional formal to save copy of
14186 the offset value in the table of interfaces.
14187 Update structure of GNAT Primary and Secondary dispatch table diagram.
14188 Add comment section on GNAT dispatch table prologue.
14189 (Offset_To_Signature): Update the constant value of the Signature field.
14190 (Dispatch_Table): Update comment on hidden fields in the prologue.
14191 (Get_Entry_Index, Get_Prim_Op_Kind, Get_Offset_Index, OSD,
14192 Set_Entry_Index, Set_Offset_Index, Set_Prim_Op_Kind, SSD, TSD): Change
14193 the type of formal parameter T to Tag, introduce additional assertions.
14194 (Get_Num_Prim_Ops, Set_Num_Prim_Ops): Remove an unnecessary type
14196 (Get_Tagged_Kind, Set_Tagged_Kind): New bodies.
14198 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
14199 in all the calls to Expand_Interface_Thunk. Instead of referencing the
14200 record component containing the tag of the secondary dispatch table we
14201 have to use the Offset_To_Top run-time function to get this information;
14202 otherwise if the pointer to the base of the object has been displace
14203 we get a wrong value if we use the 'position attribute.
14205 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
14206 all the calls to Expand_Interface_Thunk.
14207 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
14208 interfaces; hence the call to Set_Interface_Table was clearly wrong.
14209 (Collect_All_Interfaces): Modify the internal subprogram Collect to
14210 ensure that the interfaces implemented by the ancestors are placed
14211 at the header of the generated list.
14212 (Expand_Interface_Conversion): Handle the case in which the displacement
14213 associated with the interface conversion is not statically known. In
14214 this case we generate a call to the new run-time subprogram Displace.
14215 (Make_DT): Generate and fill the new table of interfaces.
14216 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
14217 Get_Tagged_Kind and Set_Tagged_Kind.
14218 (Tagged_Kind): New function that determines the tagged kind of a type
14219 with respect to limitedness and concurrency and returns a reference to
14221 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
14222 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
14223 primary dispatch table for a type.
14224 (Make_DT, Make_Secondary_DT): Set the tagged kind in the primary and
14225 secondary dispatch table respectively of a tagged type.
14227 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
14228 (Expand_Interface_Conversion): New subprogram to indicate if the
14229 displacement of the type conversion is statically known.
14230 (DT_Access_Action): Add values Get_Tagged_Kind and Set_Tagged_Kind.
14232 * rtsfind.ads (RE_Offset_To_Top): New entity
14233 (RTU_Id): Add Ada_Task_Termination to the list so that it is made

14450 (Derived_Type_Declaration): If the parent of the full-view is an
14451 interface perform a transformation of the tree to ensure that it has
14452 the same parent than the partial-view. This simplifies the job of the
14453 expander in order to generate the correct object layout, and it is
14454 needed because the list of interfaces of the full-view can be given in
14456 (Process_Full_View): The parent of the full-view does not need to be
14457 a descendant of the parent of the partial view if both parents are

14474 (Process_Full_View): Improve the check for the "no hidden interface"
14475 rule as defined by AI-396.
14477 2005-12-09 Robert Dewar <dewar@adacore.com>

14534 available user-specified stream attributes on limited parameters to
14535 also test the type directly rather than only its underlying type (for
14536 Ada 95) and, in the case of Ada 2005, to check that the user-specified
14537 attributes are visible at the point of the subprogram declaration.
14538 For Ada 2005, the error message is modified to indicate that the
14539 type's stream attributes must be visible (again, only for -gnat05).

14571 types use the corresponding record type. This was not needed before
14572 the implementation of Ada 2005 synchronized types because
14573 concurrent types were never tagged types in Ada 95.

14819 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for

14978 we are not defining the type.
14979 <E_Record_Type>: Likewise.
14980 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
14981 to get advantage of the new maybe_stabilize_reference interface, to

14983 on assumptions on what the stabilizer does.
14984 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
14985 type imported through a limited_with clause, use its non-limited view.
14986 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others

14989 of #if sections + explicit comparisons of convention identifiers.

14991 before early-returning for certain types when code generation is

14995 that we are not defining.
14996 (elaborate_expression_1): Do not create constants when creating
14997 variables needed by the debug info: the dwarf2 writer considers that
14998 CONST_DECLs is used only to represent enumeration constants, and emits
15000 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
15001 object with an address clause into an indirect reference, drop the
15002 initializing expression.

15014 subtype to build an actual type with bounds template.
15015 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
15016 is provided by the front-end, use that subtype to compute the size of
15017 the deallocated object.

15024 maybe_stabilize, for common uses without restriction on lvalues and
15025 without need to check for the success indication.
15026 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
15027 pass false instead of 0 as the FORCE argument which is a bool.
15028 (Identifier_to_gnu): Remove checks ensuring that an renamed object
15029 attached to a renaming pointer has been properly stabilized, as no such
15030 object is attached otherwise.
15031 (call_to_gnu): Invoke create_var_decl to create the temporary when the
15032 function uses the "target pointer" return mechanism.
15033 Reinstate conversion of the actual to the type of the formal
15034 parameter before any other specific treatment based on the passing

15045 static output of record constructor if all the components are constant.
15046 (gnat_build_constructor): For a record type, sort the list of field
15047 initializers in increasing bit position order.
15048 Factor common code to build a storage type for an unconstrained object
15049 from a fat or thin pointer type and a constrained object type.
15050 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
15051 types variants, and process special cases of VIEW_CONVERT expressions
15052 as their NOP_EXPR counterpart to ensure we get to the
15053 CORRESPONDING_VARs associated with CONST_DECls.
15054 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
15055 on the right-hand side.

15062 extracting the object if converting to a type variant.
15063 (create_var_decl): When a variable has an initializer requiring code
15064 generation and we are at the top level, check for a potential violation
15065 of a No_Elaboration_Code restriction.
15066 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
15067 SIZE and SIZE_UNIT which we need for later back-annotations.

15209 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
15210 for task component, in the case of a limited aggregate. The enclosed
15211 object declaration will create it earlier. Otherwise, in the case of a
15212 nested aggregate, the object may appear in the wrong scope.
15213 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
15214 (Gen_Assign): If the component being assigned is an array type and the
15215 expression is itself an aggregate, wrap the assignment in a block to
15216 force finalization actions on the temporary created for each row of the
15218 (Build_Record_Aggr_Code): Significant rewrite insuring that ctrl
15219 structures are initialized after all discriminants are set so that
15220 they can be accessed even when their offset is dynamic.

15229 'Terminated whenever the prefix is of a task interface class-wide type.
15230 (Analyze_Attribute): Add semantic check for attribute 'Identity whenever
15231 the prefix is of a task interface class-wide type.
15233 * s-vaflop-vms-alpha.adb: Valid_D, Valid_F, Valid_G: Make Val constant
15236 * s-fatgen.ads, s-fatgen.adb (Machine_Rounding): New function

15248 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
15249 and related): For a prefix that is an explicit dereference of an
15250 access to unconstrained packed array type, annotate the dereference
15251 with an actual subtype so GIGI can make a correct size computation.
15252 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
15253 'Unrestricted_Access, if the designated type is an interface we
15254 add a type conversion to force the displacement of the pointer
15255 to the secondary dispatch table.
15256 Use Universal_Real instead of Long_Long_Float when we need a high
15257 precision float type for the generated code (prevents gratuitous
15258 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
15259 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
15260 'Terminated for task interface class-wide objects. Generate a call to
15261 the predefined dispatching routine used to retrieve the _task_id from
15262 a task corresponding record.

15284 necessary for the statements within the block: analyze it with checks
15286 (Expand_N_If_Statement): When killing a dead then-branch in an
15287 if-statement that has elsif_parts, recompute the Current_Value node
15288 for any entity whose value is known from the condition of the first
15290 (Expand_N_Return_Statement): When returning a mutable record, convert
15291 the return value into its actual subtype in order to help the backend
15292 to return the actual size instead of the maximum. This is another
15293 aftermath of not returning mutable records on the sec-stack anymore.
15295 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
15296 handling of error msg for suspicious reverse range iteration.
15297 (Check_Possible_Current_Value_Condition): Move declaration from body to

15318 (Send_Signal): Release the process handle.
15320 2005-11-14 Robert Dewar <dewar@adacore.com>
15322 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we
15323 need a high precision float type for the generated code (prevents
15324 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
15327 * exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we

15342 attribute of the N_Free_Statement.
15343 Generate itype for classwide designated object in both cases of
15344 user-specified storage pool: specific and class-wide, not only in the
15346 Raise CE when trying to set a not null access type object to null.
15347 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
15348 an explicit loop, because freeze nodes make its position variable.

15526 rhs of an assignment even if the type is unconstrained, when the
15527 context is non-expanding.
15528 In an inlined body, if the context type is private,
15529 resolve with its full view, which must be a composite type.

15567 parent scopes of a scope being removed prior to inlining an instance
15569 (Analyze_Package_Instantiation): Do not perform front-end inlining when

15585 scope against package Standard. Add comments and a ??? comment.
15586 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
15587 on a child instance parent to test that the parent equals

15607 full view to construct the full declaration of the derived type.
15608 (Build_Derived_Record_Type): Relax the condition that controls the
15609 execution of the check that verifies that the partial view and

15618 view is a transitive derivation of the ancestor of the partial view.
15619 (Process_Full_View): Rename local subprogram Find_Interface_In_
15620 Descendant to Find_Ancestor_Interface to leave the code more clear.
15621 Remove wrong code that avoids the generation of an error message
15622 when the immediate ancestor of the partial view is an interface.
15623 In addition some minor reorganization of the code has been done to
15624 leave it more clear.
15625 (Analyze_Type_Declaration): If type has previous incomplete tagged
15626 partial view, inherit properly its primitive operations.
15627 (Collect_Interfaces): Make public, for analysis of formal

15639 and derived protected types, the parent may be an interface that must
15640 be included in the interface list.
15641 (Access_Definition): If the designated type is an interface that may
15642 contain tasks, create Master_Id for it before analyzing the expression
15643 of the declaration, which may be an allocator.
15644 (Record_Type_Declaration): Set properly the interface kind, for use
15645 in allocators, the creation of master id's for task interfaces, etc.

15654 subprogram declaration.
15655 Change name Is_Package to Is_Package_Or_Generic_Package
15656 (Process_Formals): A non null qualifier on a non null named access
15657 type is not an error, and is a warning only if Redundant_Constructs

15661 Ed Schonberg <schonberg@adacore.com>
15663 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
15664 nested within Analyze_Package_Specification to install the private
15665 declarations and use clauses within each of the parent units of a
15666 package instance of a generic child package.
15667 (Analyze_Package_Specification): When entering a private part of a
15668 package associated with a generic instance or formal package, the
15669 private declarations of the parent must be installed (by calling new
15670 procedure Install_Parent_Private_Declarations).
15671 Change name Is_Package to Is_Package_Or_Generic_Package
15672 (Preserve_Full_Attributes): For a synchronized type, the corresponding
15673 record is absent in a generic context, which does not indicate a

15678 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
15679 not try to rewrite a renamed stream attribute, because the operations
15680 on the type may not have been generated.
15681 Handle properly a renaming_as_body generated for a stream operation
15682 whose default is abstract because the object type itself is abstract.
15683 (Find_Type): If the type is incomplete and appears as the prefix of a
15684 'Class reference, it is tagged, and its list of primitive operations
15685 must be initialized properly.
15686 (Chain_Use_Clauses): When chaining the use clauses that appear in the
15687 private declaration of a parent unit, prior to compiling the private
15688 part of a child unit, find on the scope stack the proper parent entity
15689 on which to link the use clause.
15690 (Note_Redundant_Use): Emit a warning when a redundant use clause is
15692 (Analyze_Object_Renaming): An attribute reference is not a legal object
15693 if it is not a function call.

15698 * sem_eval.adb: Implement d.f flag
15699 (Subtype_Statically_Match): A generic actual type has unknown
15700 discriminants when the corresponding actual has a similar partial view.
15701 If the routine is called to validate the signature of an inherited
15702 operation in a child instance, the generic actual matches the full view,

15710 a procedure call is used as a select statement trigger and is not an
15711 entry renaming or a primitive of a limited interface.
15712 (Valid_Conversion): If the operand has a single interpretation do not
15713 remove address operations.
15714 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
15715 statement to inhibit warning.
15716 (Resolve_Unary_Op): Do not produce a warning when
15717 processing an expression of the form -(A mod B)
15718 Use Universal_Real instead of Long_Long_Float when we need a high
15719 precision float type for the generated code (prevents gratuitous
15720 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
15721 (Resolve_Concatenation_Arg): Improve error message when argument is an
15722 ambiguous call to a function that returns an array.
15723 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
15724 there is an implicit operator in the given scope if we are within an
15725 instance: legality check has been performed on the generic.
15726 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
15727 after resolving operand, to avoid false warnings on overloaded calls.
15729 2005-11-14 Ed Schonberg <schonberg@adacore.com>
15730 Javier Miranda <miranda@adacore.com>
15733 * sem_type.adb (Covers): In an inlined body, a composite type matches
15734 a private type whose full view is a composite type.
15735 (Interface_Present_In_Ancestor): Protect the frontend against
15736 previously detected errors to ensure that its compilation
15737 with assertions enabled gives the same output that its
15738 compilation without assertions.
15739 (Interface_Present_In_Ancestor): Add support for private types.
15740 Change name In_Actual to In_Generic_Actual (clean up)
15741 (Disambiguate): New predicate In_Actual, to recognize expressions that
15742 appear in the renaming declaration generated for generic actuals, and
15743 which must be resolved in the outer context.

15757 for a parameterless procedure.
15758 (Enter_Name): Recognize renaming declarations created for private
15759 component of a protected type within protected operations, so that
15760 the source name of the component can be used in the debugger.

16419 (Write_Field26_Name): Add entry for Overridden_Operation
16420 (Overridden_Operation): New attribute of functions and procedures.
16422 * exp_disp.ads, exp_disp.adb (Default_Prim_Op_Position): Return a
16423 predefined position in the dispatch table for the primitive operations
16424 used in dispatching selects.
16425 (Init_Predefined_Interface_Primitives): Remove the hardcoded number of
16426 predefined primitive operations and replace it with
16427 Default_Prim_Op_Count.
16428 (Make_Disp_Asynchronous_Select_Spec, Make_Disp_Conditional_Select_Spec,
16429 Make_Disp_Get_Prim_Op_Kind_Spec, Make_Disp_Timed_Select_Spec): Update
16430 the names of the generated primitive operations used in dispatching
16432 (Init_Predefined_Interface_Primitives): No need to inherit primitives in
16433 case of abstract interface types. They will be inherit by the objects
16434 implementing the interface.
16435 (Make_DT): There is no need to inherit the dispatch table of the
16436 ancestor interface for the elaboration of abstract interface types.
16437 The dispatch table will be inherited by the object implementing the

16444 the entries associated with predefined primitives of all the secondary
16446 (Build_Anonymous_Access_Type): Removed.
16447 (Expand_Interface_Actuals): With the previous cleanup there is no need
16448 to build an anonymous access type. This allows further cleanup in the
16449 code generated by the expander.
16450 (Expand_Interface_Conversion): If the actual is an access type then
16451 build an internal function to handle the displacement. If the actual
16452 is null this function returns null because no displacement is
16453 required; otherwise performs a type conversion that will be
16454 expanded in the code that returns the value of the displaced actual.
16455 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
16456 conversions that have no effect in the generated code because no
16457 displacement is required. Code cleanup; use local variables to
16458 avoid repeated calls to the subprogram directly_designated_type().
16460 * exp_util.ads, exp_util.adb (Is_Predefined_Dispatching_Operation):
16461 Classify the primitive operations used in dispatching selects as
16463 (Implements_Limited_Interface): Determine whether some type either

16465 implements a limited interface.
16466 (Build_Task_Image_Function): Change Subtype_Mark to Result_Definition.
16467 (Expand_Subtype_From_Expr): Do not build actual subtype if the
16468 expression is limited.
16469 (Find_Interface_Tag): Add code to handle class-wide types and
16470 entities from the limited-view.
16472 * rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
16473 Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,
16474 POK_Protected_Entry, POK_Protected_Function, POK_Protected_Procedure,
16475 POK_Task_Entry, POK_Task_Procedure, Prim_Op_Kind, Set_Entry_Index,

16497 * s-taprop-vxworks.adb:
16498 Move with clauses outside Warnings Off now that dependent units are
16500 (Initialize): Call Interrupt_Managemeent.Initialize to ensure proper
16501 initialization of this unit.
16502 (Specific): Add new procedures Initialize and Delete so that this
16503 package can be used for VxWorks 5.x and 6.x
16504 (ATCB_Key, ATCB_Key_Address): Moved to Specific package body to hide
16505 differences between VxWorks 5.x and 6.x
16506 Minor reformatting.
16507 (Timed_Delay): Remove calls to Defer/Undefer_Abort, now performed by
16509 Use only Preelaborate-compatible constructs.
16511 * s-tpopsp-vxworks.adb (ATBC_Key, ATCB_Key_Addr): Moved from
16512 Primitives.Operations.
16513 (Delete, Initialize): New procedures.

16521 (VX_FP_TASK): Now a function, to handle differences between VxWorks 5
16523 (Set_Time_Slice): New function, replacing kerneltimeSlice to share code
16524 between Vxworks 5 and 6.
16525 (taskLock, taskUnlock): Removeed, no longer used.
16527 * adaint.c: The wait.h header is not located in the sys directory on
16528 VxWorks when using RTPs.
16529 (__gnat_set_env_value): Use setenv instead of putenv on VxWorks when
16531 (__gnat_dup): dup is available on Vxworks when using RTPs.
16532 (__gnat_dup2): dup2 is available on Vxworks when using RTPs.
16534 * cal.c: Use the header time.h for Vxworks 6.0 when using RTPs.
16536 * expect.c: The wait.h header is not located in the sys directory on
16537 VxWorks when using RTPs.

16550 SO_RCVTIMEO/SO_SNDTIMEO
16554 Move all target-specific file inclusions and macro definitions to
16555 gsocket.h, in order to ensure that any C code in socket.c will see a
16556 set of constants that is consistent with the contents of g-soccon.ads.
16558 * gsocket.h: Code imported from gen-soccon.c:
16559 Move all target-specific file inclusions and macro definitions to
16560 gsocket.h, in order to ensure that any C code in socket.c will see a set
16561 of constants that is consistent with the contents of g-soccon.ads.
16562 This change also makes gen-soccon self-contained (removing dependencies
16563 upon GCC internal headers).
16565 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
16567 (To_Inet_Addr): Now a procedure instead of a function, more efficient.
16569 * socket.c: Minor reformatting.

16701 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
16702 from object notation, the original node is unanalyzed and carries no
16703 semantic information, so that accessiblity checks must be performed on
16704 the type of the actual itself.
16705 (Expand_N_Subprogram_Declaration): Change last actual parameter for
16706 compatibility with Build_Protected_Sub_Specification.
16707 (Check_Overriding_Inherited_Interfaces): Add suport to handle

16717 load comes from a Limited_With_Clause.
16719 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
16720 whether a potential circularity is harmless, because it includes units
16721 loaded through a limited_with clause. Extends previous treatment which
16722 did not handle properly arbitrary combinations of limited and
16723 non-limited clauses.
16725 2005-09-01 Nicolas Setton <setton@adacore.com>
16727 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types

16757 2005-09-01 Laurent Pautet <pautet@adacore.com>
16759 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
16760 position set is provided, we compute one in order to reduce the maximum
16761 length of the keys. This computation first selects a character
16762 position between 1 and the minimum length of the keys in order to
16763 avoid reducing one of the keys to an empty string.
16764 (Initialize, Compute): When the ratio V to K is too low, the algorithm
16765 does not converge. The initialization procedure now comes with a
16766 maximum number of iterations such that when exceeded, an exception is
16767 raised in Compute. The user can initialize this ratio to another value
16769 Reformating and updated headers.

16773 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
16774 that given an entity T creates and returns an Itype that duplicates the
16775 contents of T. The returned Itype has the null-exclusion
16776 attribute set to True, and its Etype attribute references T
16777 to keep the association between the two entities.
16778 Update copyright notice
16780 * sem_aggr.adb (Check_Can_Never_Be_Null,
16781 Aggregate_Constraint_Checks, Resolve_Aggregate,
16782 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.

16797 plus null exclusions. Call Set_Result_Definition instead of
16800 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
16801 (P_Access_Type_Definition): Add parsing for an anonymous access result
16802 subtype, plus parsing for null exclusions. Call Set_Result_Definition
16803 instead of Set_Subtype_Mark.
16805 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
16806 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
16807 (Result_Definition): New function for N_Function_Specifications.

16809 N_Function_Specification.
16810 (Set_Null_Exclusion_Present): Allow this flag for
16811 N_Function_Specification.
16812 (Set_Result_Definition): New procedure for N_Function_Specifications.
16813 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
16814 and N_Function_Specification.
16816 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
16817 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
16818 Add support for LIMITED NEW for Ada 2005 AI-419
16819 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
16820 syntax for anonymous access results.

16822 N_Function_Specification and N_Access_Definition specs.
16823 Add Null_Exclusion_Present to spec of N_Function_Specification.
16824 (Result_Definition): New function for N_Function_Specification and
16825 N_Access_Function_Definition.
16826 (Set_Result_Definition): New procedure for N_Function_Specification and
16827 N_Access_Function_Definition.

16830 Result_Definition for cases of N_Access_Function_Definition and
16831 N_Function_Specification.
16832 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
16834 2005-09-01 Vincent Celier <celier@adacore.com>
16836 * lib-writ.adb: Update Copyright notice
16837 (Write_With_Lines): On platforms where file names are case-insensitive,
16838 record the file names in lower case.
16839 (Write_ALI): For D lines, on platforms where file names are
16840 case-insensitive, record the file names in lower case.

16859 including those that are inherited.
16861 2005-09-01 Robert Dewar <dewar@adacore.com>
16863 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
16865 * par-prag.adb: Implement new pragma Debug_Policy
16867 * sem_prag.adb Implement new pragma Debug_Policy
16868 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
16869 Component_Size attribute specification. Give warning for ignored pragma
16872 * snames.h, snames.ads, snames.adb: Introduce entries in
16873 Preset_Names for Name_Disp_Asynchronous_Select,
16874 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
16875 Name_Disp_Timed_Select.
16876 New pragma Debug_Policy

16880 Switch -gnata also sets Debug_Pragmas_Enabled
16882 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
16883 handle an explicit -gnata when compiling predefined files.

16887 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
16888 directories of projects that have no Ada sources.
16890 2005-09-01 Robert Dewar <dewar@adacore.com>
16892 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
16893 (makes a difference for wide characters)
16895 * widechar.adb, widechar.ads:
16896 Add Wide_Char_Byte_Count feature to count chars vs bytes

16899 Ed Schonberg <schonberg@adacore.com>
16900 Robert Dewar <dewar@adacore.com>
16902 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
16903 'Address attribute reference with an overloaded prefix, use the
16904 location of the prefix (not the location of the attribute reference) as
16905 the error location.
16906 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
16907 a function renaming thereof, is a valid prefix for 'Size (where it is
16908 intepreted as a function call).
16909 (Statically_Denotes_Entity): New predicate to determine whether the
16910 prefix of an array attribute can be considered static.
16913 (Eval_Attr): Fix failure to evaluate Component_Size for
16914 unconstrained arrays (resulted in wrong value in packed case, since
16915 back end cannot handle this case)
16917 2005-09-01 Robert Dewar <dewar@adacore.com>
16919 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
16920 error msgs for most common cases.
16921 Use new errout insertion char < (conditional warning)
16923 2005-09-01 Javier Miranda <miranda@adacore.com>
16924 Ed Schonberg <schonberg@adacore.com>
16926 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
16927 become local to the whole package.
16928 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
16929 the package was already analyzed the new algorithm "replaces" the
16930 real entities by the shadow ones. This is required to ensure that
16931 the order of these entities in the homonym chains does not change;
16932 otherwise we can have undefined references at linking time because
16933 in case of conflicts the external name of the entities will have
16934 a suffix that depends on the order of the entities in the chain.
16935 (Remove_Limited_With_Clause): Complementary code that completes the
16936 new algorithm and replaces the shadow entities by the real ones.
16937 (Install_Limited_Withed_Unit): When unchaining entities before the
16938 installation of the shadow entities, only regular entities of the
16939 public part must be taken into account. This is required to
16940 keep this routine in synch with the work done by Remove_Limited_
16942 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
16943 even if unit is analyzed, because the analysis of the unit is
16944 idempotent in any case, and the limited view of the unit may have to
16945 be installed for proper visibility.
16946 (Expand_Limited_With_Clause): Even if the unit in the implicit
16947 with_clause has been analyzed already, a limited view of the package
16948 must be built for the current context, if it does not exist yet.
16950 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16951 Javier Miranda <miranda@adacore.com>
16952 Gary Dismukes <dismukes@adacore.com>
16954 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
16955 defining entity for the instance body, make a new defining identifier
16956 rather than copying the entity of the spec, to prevent accidental
16957 sharing of the entity list.
16958 (Check_Private_View): When exchanging views of private types, build the
16959 list of exchanged views as a stack, to ensure that on exit the exchanges
16960 are undone in the proper order.
16961 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
16962 Restore the compilation environment in case of instantiation_error.
16963 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
16964 for an anonymous access result.
16965 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
16966 (Formal_Entity): Handle properly the case of a formal package that
16967 denotes a generic package renaming.
16969 2005-09-01 Thomas Quinot <quinot@adacore.com>
16971 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
16972 clause if the array aggregate is surrounded by parentheses.
16974 2005-09-01 Cyrille Comar <comar@adacore.com>
16975 Gary Dismukes <dismukes@adacore.com>
16976 Ed Schonberg <schonberg@adacore.com>
16977 Javier Miranda <miranda@adacore.com>
16979 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
16981 to check if a type is Constrained in cases related to code generation
16982 (rather than semantic checking) since otherwise we do not generate
16983 similar code for mutable private types depending if their
16984 discriminants are visible or not.
16985 (Check_Abstract_Overriding): Do not complain about failure to override
16986 the primitive operations used in dispatching selects since they will
16987 always be overriden at the freeze point of the type.
16988 (Access_Definition): Separate out handling for resetting the scope
16989 of an anonymous access function result type. Retrieve the scope
16990 of the associated function rather than using Current_Scope, which
16991 does not have a consistent value (depends on whether we're in the
16992 middle of analyzing formal parameters). Add ??? comment about
16993 finding a cleaner way to handle the special cases of scope setting.
16994 (Process_Incomplete_Dependents): A protected operation is never a
16995 dispatching operation (only its wrapper may be).
16996 (Build_Derived_Record_Type): In case of tagged private types that
16997 implement interfaces add derivation of predefined primitive
16999 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
17000 by two parameters that are used in case of derivation from abstract
17001 interface types: No_Predefined_Prims is used to avoid the derivation
17002 of predefined primitives from the interface, and Predefined
17003 Prims_Only is used to complete the derivation predefined primitives
17004 in case of private tagged types implementing interfaces.
17005 Fix typo in comments
17006 (Find_Interface_In_Descendant): Protect the frontend against
17007 wrong code with large circularity chains.
17008 (Is_Private_Overriding): Add support for entities overriding interface
17009 subprograms. The test failed because Entities associated with overriden
17010 interface subprograms are always marked as hidden (and used to build
17011 the secondary dispatch table); in this case the overriden entity is
17012 available through the field abstract_interface_alias (cf. override_
17013 dispatching_operation)
17014 (Access_Definition): Set the scope of the type to Current_Scope for the
17015 case of a function with an anonymous access result type.
17016 (Access_Subprogram_Declaration): Handle creation of the type entity for
17017 an access-to-function type with an anonymous access result.
17018 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
17019 in handling for N_Access_Function_Definition.
17020 (Analyze_Subtype_Declaration): Modify the text of error message.
17021 (Derived_Type_Declaration): Modify the text of error message.
17022 (Process_Subtype): Modify the text of error message plus cleanup
17023 of one redundant error message.
17024 (Analyze_Component_Declaration): Code cleanup.
17025 (Analyze_Object_Declaration): Code cleanup.
17026 (Analyze_Subtype_Declaration): Propagate the null-exclusion
17027 attribute in case of access types. Code cleanup.
17028 (Array_Type_Declaration): Code cleanup.
17029 (Process_Discriminants): Create the new null-excluding itype
17030 if required. Code cleanup.
17031 (Process_Subtype): Create the new null-excluding itype if
17032 required. Code cleanup.
17033 (Build_Derived_Record_Type): Code cleanup to avoid calling
17034 twice the subprogram derive_subprograms in case of private
17035 types that implement interfaces. In this particular case the
17036 subprogram Complete_Subprograms_Derivation already does the
17037 job associated with the second call.
17039 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
17040 conversion to the full view when generating an operation for a
17041 discriminant whose type may currently be private.
17043 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17044 Javier Miranda <miranda@adacore.com>
17046 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
17047 V (Obj.F), the rewriting does not involve the indexed component, but
17048 only the selected component itself.
17049 Do not apply the transformation if the analyzed node is an actual of a
17050 call to another subprogram.
17051 (Complete_Object_Operation): Retain the entity of the
17052 dispatching operation in the selector of the rewritten node. The
17053 entity will be used in the expansion of dispatching selects.
17054 (Analyze_One_Call): Improve location of the error message associated
17056 (Analyze_Selected_Component): No need to resolve prefix when it is a
17057 function call, resolution is done when parent node is resolved, as
17059 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
17060 when attempting to resolve a call transformed from its object notation.
17061 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
17062 of the argument list for each interpretation of the operation.
17063 (Try_Object_Operation): The designated type of an access parameter may
17064 be an incomplete type obtained through a limited_with clause, in which
17065 case the primitive operations of the type are retrieved from its full
17067 (Analyze_Call): If this is an indirect call, and the return type of the
17068 access_to_subprogram is incomplete, use its full view if available.
17070 2005-09-01 Javier Miranda <miranda@adacore.com>
17071 Gary Dismukes <dismukes@adacore.com>
17073 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
17074 access types the null-exclusion and access-to-constant attributes must
17076 (Analyze_Return_Statement): When the result type is an anonymous access
17077 type, apply a conversion of the return expression to the access type
17078 to ensure that appropriate accessibility checks are performed.
17079 (Analyze_Return_Type): For the case of an anonymous access result type,
17080 generate the Itype and set Is_Local_Anonymous_Access on the type.
17081 Add ??? placeholder for check to disallow returning a limited object
17082 in Ada 2005 unless it's an aggregate or a result of a function call.
17083 Change calls from Subtype_Mark to Result_Definition.
17084 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
17085 Result_Definition in call to Make_Function_Specification.
17086 (Build_Body_To_Inline): Change Set_Subtype_Mark to
17087 Set_Result_Definition.
17088 (Make_Inequality_Operator): Change formal Subtype_Mark to
17089 Result_Definition in call to Make_Function_Specification.
17090 (Process_Formals): Create the new null-excluding itype if required.
17091 (New_Overloaded_Entity): For an entity overriding an interface primitive
17092 check if the entity also covers other abstract subprograms in the same
17093 scope. This is required to handle the general case, that is, overriding
17094 other interface primitives and overriding abstract subprograms inherited
17095 from some abstract ancestor type.
17096 (New_Overloaded_Entity): For an overriding entity that comes from
17097 source, note the operation that it overrides.
17098 (Check_Conformance, Type_Conformant): Addition of one new formal
17099 to skip controlling formals in the analysis. This is used to
17100 handle overloading of abstract interfaces.
17101 (Base_Types_Match): Add missing case for types imported from
17102 limited-with clauses
17103 (New_Overloaded_Entity): Add barrier to protect the use of
17104 the "alias" attribute.
17106 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17108 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
17109 verify that the procedure and the entry are mode conformant.
17110 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
17111 as a different operator, which is often a cut-and-paste error.
17113 2005-09-01 Javier Miranda <miranda@adacore.com>
17114 Ed Schonberg <schonberg@adacore.com>
17116 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
17117 used in controlling parameters exclude null because it is necessary to
17118 read the tag to dispatch, and null has no tag.
17119 (Override_Dispatching_Operation): If the previous operation is inherited
17120 from an interface, it becomes hidden and does not participate in later
17123 2005-09-01 Javier Miranda <miranda@adacore.com>
17124 Ed Schonberg <schonberg@adacore.com>
17125 Gary Dismukes <dismukes@adacore.com>
17127 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
17128 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
17129 the expander will generate the corresponding run-time check to evaluate
17131 (Resolve_Call): Check for legal type of procedure name or prefix that
17132 appears as a trigger in a triggering alternative.
17133 (Valid_Conversion): If expression is ambiguous and the context involves
17134 an extension of System, remove System.Address interpretations.
17135 (Resolve_Qualified_Expression): Reject the case of a specific-type
17136 qualification applied to a class-wide argument. Enhance comment
17137 to explain checking of Original_Node.
17138 (Resolve_Type_Conversion): The location of the error message was not
17139 general enough to handle the general case and hence it has been removed.
17140 In addition, this patch improves the text of the message.
17141 (Resolve_Type_Conversion): Add missing support for access to interface
17143 (Resolve_Type_Conversion): If the target is a class-wide interface type,
17144 do not expand if the expression is the actual in a call, because proper
17145 expansion will take place when the call itself is expanded.
17146 (Resolve_Allocator): If the context is an unchecked conversion, the
17147 allocator inherits its storage pool, if any, from the target type of
17150 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17151 Javier Miranda <miranda@adacore.com>
17153 * sem_type.adb (Add_One_Interp): If a candidate operation is an
17154 inherited interface operation that has an implementation, use the
17155 implementation to avoid spurious ambiguities.
17156 (Interface_Present_In_Ancestor): In case of concurrent types we can't
17157 use the Corresponding_Record_Typ attribute to look for the interface
17158 because it is set by the expander (and hence it is not always
17159 available). For this reason we traverse the list of interfaces
17160 (available in the parent of the concurrent type).
17161 (Interface_Present_In_Ancestor): Handle entities from the limited view
17163 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17165 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
17166 from the list of required components.
17167 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
17168 primitive procedure of a limited interface with a controlling first
17170 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
17172 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
17173 capture if it is generated in the second operand of a short-circuit
17175 Do not capture values for variables with address clauses.
17176 (Is_Object_Reference): Treat a function call as an object reference only
17177 if its type is not Standard_Void_Type.
17179 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17181 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
17182 to a variable that is statically known to be constant.

17194 Document that bounds of result of Base_Name match the input index
17196 Add documentation on environment variable syntax for Expand_Path
17198 * gnat_ugn.texi: Update documentation to include mention of -m switches
17199 Document new treatment of wide characters in max line length
17201 Remove -gnatL/-gnatZ switches, no longer used.
17202 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
17205 * gnat_rm.texi: Add doc for two argument form of pragma
17206 Float_Representation.
17207 Add documentation for pragma No_Strict_Aliasing
17208 Add note that explicit component clause overrides pragma Pack.
17209 Add documentation of pragma Debug_Policy

17964 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
17965 longer protected objects. They have been replaced by lower-level
17966 suspension objects made up by a mutex and a condition variable (or
17967 their equivalent given a particular OS) plus some internal data to
17968 reflect the state of the suspension object.
17969 (Initialize, Finalize): Add this initialization procedure for
17970 Suspension_Object, which is a controlled type.
17971 (Finalize): Add the finalization procedure for Suspension_Object,
17972 which is a controlled type.
17974 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
17975 Ada.Synchronous_Task_Control because there is no longer a need for a
17976 VxWorks specific version of this package. Target dependencies
17977 has been moved to System.Task_Primitives.Operations.
17979 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
17981 (InitializeCriticalSection, EnterCriticalSection,
17982 LeaveCriticalSection, DeleteCriticalSection): Replace the type
17983 pCriticalSection by an anonymous access type so that we avoid problems
17984 of accessibility to local objects.
17986 * s-taprop.ads, s-taprop-posix.adb, s-taprop-vxworks.adb,

17990 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
17991 set the environment task mask here.
17992 (Current_State): Add this function that returns the state of the
17994 (Set_False): Add this procedure that sets the state of the suspension
17996 (Set_True): Add this procedure that sets the state of the suspension
17997 object to True, releasing the task that was suspended, if any.
17998 (Suspend_Until_True): Add this procedure that blocks the calling task
17999 until the state of the object is True. Program_Error is raised if
18000 another task is already waiting on that suspension object.
18001 (Initialize): Add this procedure for initializing the suspension
18002 object. It initializes the mutex and the condition variable which are
18003 used for synchronization and queuing, and it sets the internal state
18005 (Finalize): Add this procedure for finalizing the suspension object,
18006 destroying the mutex and the condition variable.

18011 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
18012 which provides a low-level abstraction (using operating system
18013 primitives) for Ada.Synchronous_Task_Control.
18014 This object is made up by a mutex (for ensuring mutual exclusion), a
18015 condition variable (for queuing threads until the condition is
18016 signaled), a Boolean (State) indicating whether the object is open,
18017 and a Boolean (Waiting) reflecting whether there is a task already
18018 suspended on this object.

18211 * exp_ch5.adb (Expand_N_Return_Statement): When a function's result
18212 type is a class-wide type, emit a run-time check that the accessibility

18283 type derivation of private tagged types implementing interfaces.
18284 In this case some interface primitives may have been overriden

18288 types implemening interfaces.
18289 (Access_Definition): Reject ALL on anonymous access types.

18374 * i-cpp.ads, i-cpp.adb:
18375 This package has been left available for compatibility with previous
18376 versions of the frontend. As part of the new layout this is now a

18414 on subprogram stubs as well.
18415 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
18417 (Analize_Subprogram_Specification): When analyzing a subprogram in which

18419 by the corresponding record type.
18420 (Analyze_Subprogram_Body): Undo the previous work.
18421 (Analyze_Procedure_Call): If the call has the form Object.Op, the
18422 analysis of the prefix ends up analyzing the call itself, after which
18424 (Has_Interface_Formals): New subprogram subsidiary to analyze
18425 subprogram_specification that returns true if some non
18426 class-wide interface subprogram is found
18427 (New_Overloaded_Entity): Modified to give support to abstract

18430 access to subprograms must be recursive.
18431 (Is_Unchecked_Conversion): Improve the test that recognizes
18432 instantiations of Unchecked_Conversion, and allows them in bodies that
18433 are to be inlined by the front-end. When the body comes from an
18434 instantiation, a reference to Unchecked_Conversion will be an
18435 Expanded_Name, even though the body has not been analyzed yet.

18455 in the case where the target type is an anonymous access type of an
18456 object or component (that is, when Is_Local_Anonymous_Access is true).
18457 Prevent the special checks for conversions of access discriminants in
18458 the case where the discriminant belongs to a nonlimited type, since
18459 such discriminants have their accessibility level defined in the same
18460 way as a normal component of an anonymous access type.
18461 (Resolve_Allocator): When an allocator's designated type is a class-wide

19491 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
19492 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
19493 analyzed if expansion is disabled (which could otherwise cause spurious
19494 error messages if expansion has been disabled due to previous
19495 (unrelated) errors).
19497 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
19498 is disabled, the entity denoted by the argument is the access type
19499 itself, not an underlying record type, so there is no need to go back
19500 to the Corresponding_Remote_Type.

19510 denotes a type in the class.
19511 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
19512 of Name_Generic_Dispatching_Constructor.
19514 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

19532 a class-wide stream attribute) and then rewrite the attribute name
19533 as the name of the appropriate compiler-generated stream primitive.

19545 itype whose parent is controlled and not yet frozen, do not create a
19546 freeze node for the itype if expansion is disabled.
19548 2005-03-29 Vincent Celier <celier@adacore.com>
19550 * make.adb (Gnatmake): Don't fail if the main project file is declared
19551 as having no Ada sources. Do not display message "no sources to

19572 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
19573 rather than proceed ahead using a junk attribute name.
19575 2005-03-29 Vincent Celier <celier@adacore.com>
19577 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
19579 * prj-part.adb (Parse_Single_Project): Set the location of a project
19580 on its defining identifier, rather than on the reserved word "project".
19582 * prj-proc.adb (Expression): Adapt to the fact that default of external
19583 references may be string expressions, not always literal strings.
19584 (Recursive_Process): Set Display_Name equal to Name
19585 when Location is No_Location, that is when there is no actual file.
19586 Get the Display_Name of the project from the source, when it is not a
19588 (Process): Use the Display_Name in error messages
19590 * prj-strt.adb (External_Reference): Allow default to be string
19591 expressions, not only literal strings.

19604 equivalent type for a remote access-to-subprogram type, go back to the
19605 original RAS entity when displaying an error message, so the casing is
19606 the original source casing.

19615 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
19616 subtype if code is being pre-analyzed, to prevent un-expanded
19617 references to protected formals, among others.
19618 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
19619 interpretation that can be a call, include the result of the call as a
19620 possible interpretation of the dereference.
19622 * sem_ch5.adb (Process_Bounds): Determine type of range by
19623 pre-analyzing a copy of the original range, and then analyze the range
19624 with the expected type.
19626 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
19627 with an overloaded prefix where not all interpretations yield an
19628 access to subprogram, do not rewrite node as a call.
19629 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
19630 the node as a call once the context identifies the interpretation of
19631 the prefix whose call yields the context type.
19632 (Valid_Conversion): For the case of a conversion between
19633 local access-to-subprogram types, check subtype conformance using
19634 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
19635 detailed error message.

19639 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
19640 indicator, indicate that the formal can never be null.
19641 (Process_Formals): If a formal has a non_null indicator, insert the
19642 resulting subtype immediately before the enclosing subprogram decl,
19643 and not at the beginning of the corresponding declarative part, to
19644 prevent access before elaboration (Ada2005).

19769 subprogram determines whether a default implementation exists for a
19770 given stream attribute.
19771 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
19772 Determine whether to generate a default implementation for each stream
19773 attribute separately, as this depends on the specific attribute.

19776 limited extension where a stream attribute is missing for a limited
19777 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

20376 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
20377 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
20378 expression to the type of the object when the object is constant.
20379 Reverse defer_debug_incomplete_list before traversing it, so that trees
20380 are processed in the order at which they were added to the list. This
20381 order is important when using the stabs debug format.
20382 If we are deferring the output of debug information, also defer this
20383 output for a function return type.
20384 When adding fields to a record, prevent emitting debug information
20385 for incomplete records, emit the information only when the record is
20387 (components_to_record): New parameter defer_debug.
20388 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
20389 (gnat_to_gnu_field_decl): New function.
20390 (substitution_list, annotate_rep): Call it.
20391 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
20392 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
20393 No longer update discriminants to not be a COMPONENT_REF.
20394 (copy_alias_set): Strip padding from input type; also handle
20395 unconstrained arrays properly.
20397 * gigi.h (write_record_type_debug_info): New function.
20398 Convert to use ANSI-style prototypes. Remove unused
20399 declarations for emit_stack_check, elab_all_gnat and
20400 set_second_error_entity.
20401 (gnat_to_gnu_field_decl): New decl.
20403 * utils.c (write_record_type_debug_info): New function.
20404 (finish_record_type): Delegate generation of debug information to
20405 write_record_type_debug_info.
20406 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
20407 (update_pointer_to): Fix pasto.
20408 (convert) <UNION_TYPE>: Accept slight type variations when
20409 converting to an unchecked union type.
20411 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
20412 replace the N_Freeze_Entity with a null statement.
20414 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
20415 within a constrained subcomponent of an enclosing record, place the
20416 freeze nodes in the scope stack entry for the enclosing record.
20417 (Undelay_Type): New Subprogram.
20418 (Set_Small_Size): Pass T, the type to modify; all callers changed.
20419 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
20420 within records; allow them to have freeze nodes if their base types
20423 * exp_util.adb (Remove_Side_Effects): Properly test for
20424 Expansion_Delayed and handle case when it's inside an
20425 N_Qualified_Expression.
20427 * sem_ch3.adb (Derived_Type_Declaration): New predicate
20428 Comes_From_Generic, to recognize accurately that the parent type in a
20429 derived type declaration can be traced back to a formal type, because
20430 it is one or is derived from one, or because its completion is derived
20432 (Constrain_Component_Type): If component comes from source and has no
20433 explicit constraint, no need to constrain in in a subtype of the
20435 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
20436 Minor change to propagate Is_Ada_2005 flag
20438 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
20439 Expansion_Delayed is False.
20440 (assoc_to_constructor): Ignore fields that have a
20441 Corresponding_Discriminant.
20442 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
20443 function returns "by target", dereference the target pointer using the
20444 type of the actual return value.
20445 <all>: Be prepared for a null gnu_result.
20446 (processed_inline_subprograms): Check flag_really_no_inline
20447 instead of flag_no_inline.
20448 (set_second_error_entity): Remove unused function.
20449 (gnat_to_gnu, case N_Selected_Component): Call
20450 gnat_to_gnu_field_decl.
20451 (assoc_to_constructor): Likewise.
20453 2005-03-15 Robert Dewar <dewar@adacore.com>
20454 Ed Schonberg <schonberg@adacore.com>
20455 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
20457 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
20458 Must_Be_Byte_Aligned for cases where we do not need to use a
20459 System.Pack_nn unit.
20461 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
20463 Needed now that we do some processing for IN parameters as well. This
20464 may well fix some unrelated errors.
20465 (Expand_Call): Handle case of unaligned objects (in particular those
20466 that come from packed arrays).
20467 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
20468 renamed entity is an inherited operation, re-expand the call using the
20469 original operation, which is the one to call.
20470 Detect attempt to inline parameterless recursive subprogram.
20471 (Represented_As_Scalar): Fix to work properly with private types
20472 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
20473 accurate estimate. Yields True in far fewer cases than before,
20474 improving the quality of code that depends on this test.
20476 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
20477 over both visible and private declarations to remove them from tree,
20478 and mark subprograms declared in package as eliminated, to prevent
20479 spurious use in subsequent compilation of generic units in the context.
20481 * exp_util.ads: Minor cleanup in variable names
20483 * sem_eval.ads, sem_eval.adb: Minor reformatting
20484 (Compile_Time_Known_Bounds): New function
20486 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20488 * exp_ch7.adb (Convert_View): Use base types of underlying types when
20489 determining whether an unchecked conversion is needed for the argument
20490 of an initialization call.
20492 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20494 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
20495 that appears in the instantiation rather than the internal subtype
20496 generated in the wrapper package, to avoid anomalies in gigi when the
20497 target is derived from a private type whose full view is an access type.
20499 2005-03-15 Robert Dewar <dewar@adacore.com>
20501 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
20503 Add documentation to replace the use of this flag
20504 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
20507 2005-03-15 Thomas Quinot <quinot@adacore.com>
20509 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
20510 here from exp_attr so it can be shared between exp_attr and exp_dist.
20511 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
20512 all TSS names, not a subset thereof, and the previous name introduced
20513 an unnecessarily confusion that a distinction might exist between
20514 "OK" TSS names and some "not OK" TSS names.
20516 2005-03-15 Doug Rupp <rupp@adacore.com>
20518 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
20521 2005-03-15 Pascal Obry <obry@adacore.com>
20522 Eric Botcazou <ebotcazou@adacore.com>
20526 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
20527 when IN_RTS. This is to work around a bootstrap path problem.
20529 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
20530 table and pass it to __gnat_install_SEH_handler().
20531 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
20533 * lang.opt: Fix specification of -fRTS=.
20535 2005-03-15 Doug Rupp <rupp@adacore.com>
20536 Bernard Banner <banner@adacore.com>
20537 Vincent Celier <celier@adacore.com>
20538 Arnaud Charlet <charlet@adacore.com>
20541 This change works fine when gnatlib is built from the gcc directory,
20542 but does not work when using the libada Makefile, since GCC_FOR_TARGET
20543 is not passed to ada/Makefile.in, so more work is needed by a
20544 Makefile/configure expert.
20546 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
20547 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
20548 Setup gnatlink switch -M for x86_64 linux, as it is already setup
20550 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
20551 Run ranlib on libgccprefix.a
20552 Define PREFIX_OBJS for Darwin, to build libgccprefix.
20553 (ADA_INCLUDE_SRCS): Split Ada packages.
20555 2005-03-15 Robert Dewar <dewar@adacore.com>
20557 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
20559 * impunit.adb: Add GNAT.UTF_32
20561 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
20563 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
20564 now uses GNAT.UTF_32).
20566 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
20567 capabilities for categorizing characters using Unicode categories
20569 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20571 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
20572 instantiation that has been rewritten as a package body, retrieve spec
20573 to generate proper name for implicit_with_clause.
20574 (Install_Parents): Recognize a parent that is an instantiation but has
20575 been rewritten as a package declaration during analysis.
20577 2005-03-15 Javier Miranda <miranda@adacore.com>
20578 Ed Schonberg <schonberg@adacore.com>
20580 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
20581 parameter reported some error we immediately return. This improves the
20582 behaviour of the frontend in case of errors.
20583 (Install_Parent, Remove_Parent): Introduce new flag
20584 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
20585 ancestor of a generic child unit, when the child is being instantiated.
20586 (Inline_Instance_Body): If we are compiling the private
20587 part or the body of a child unit, restore the proper visibility of the
20588 parents after compiling the instance body.
20590 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20591 Javier Miranda <miranda@adacore.com>
20594 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
20595 of a private type, in which case it is underlying_type that denotes
20596 the proper task. Also modified to use the new entity attribute
20597 that is directly available in the task type and task subtype entities
20598 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
20599 arrays when other dimensions than the first are constrained by
20600 discriminants of an enclosing record.
20601 (Insert_Explicit_Dereference): If the prefix is an indexed component or
20602 a combination of indexed and selected components, find ultimate entity
20603 and generate the appropriate reference for it, to suppress spurious
20605 (Note_Possible_Modification): If an entity name has no entity, return.
20606 (Is_Variable): A function call never denotes a variable.
20607 (Requires_Transient_Scope): For record types, recurse only on
20608 components, not on internal subtypes that may have been generated for
20609 constrained components.
20611 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20613 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
20614 Eliminated as candidates for resolution. Both efficient, and avoids
20615 anomalies with operators declared in deleted code.
20616 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
20617 expansion is disabled (as when compiling a generic) to prevent spurious
20618 warnings on prefixes of selected components.
20620 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20622 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
20623 attached to a list before checking whether it appears in the private
20624 declarations of the current package.
20625 (Make_Inequality_Operator): Insert declaration in proper declarative
20626 list rather than just setting the Parent field, so that
20627 Is_Private_Declaration can handle it properly.
20629 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20631 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
20632 a renaming a body, check that the renamed subprogram in not intrinsic.
20633 (Find_Direct_Name): If several use_visible entities hide
20634 each other, and the context is a predefined file compiled through
20635 rtsfind, keep only the entity that comes from a predefined file.
20637 2005-03-15 Geert Bosch <bosch@adacore.com>
20639 * s-fatgen.adb (Valid): Extend special exceptions to account for long
20640 long float padding to also cover AMD64 and IA64.
20642 2005-03-15 Gary Dismukes <dismukes@adacore.com>
20644 * s-imgwch.adb: Add with and use of Interfaces.
20645 (Img_Wide_Character): Change type of Val to Unsigned_16.
20646 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
20648 2005-03-15 Matthew Gingell <gingell@adacore.com>

20684 procedures in the bug boxes for various GNAT builds.
20686 2005-03-15 Vincent Celier <celier@adacore.com>
20688 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

20691 Arnaud Charlet <charlet@adacore.com>
20692 Robert Dewar <dewar@adacore.com>
20693 Cyrille Comar <comar@adacore.com>
20694 Sergey Rybin <rybin@adacore.com>
20696 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
20697 too specific and long-winded to be appropriate for the GNAT User's
20699 Warn about use of GCC switches not documented in the GNAT User's Guide,
20700 as these may cause generated code to not conform to Ada semantics.
20701 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
20702 Add documentation for -gnat95 and -gnat05 switches
20703 Remove paragraph documenting obsolete way to refer to third party

20828 * exp_ch3.ads, exp_ch3.adb: Fix various places where Wide_Wide_String
20829 was not taken into account.
20830 This includes proper initialization with Normalize_Scalars.
20831 (Get_Simple_Init_Val): Major rewrite for initialize scalars and
20832 normalize scalars cases (particularly the latter) to do a better job
20833 of finding invalid representations.
20835 * s-scaval.ads, s-scaval.adb: Add values for zero invalid values
20837 * s-strops.ads, s-strops.adb: Remove string normalize routines, never
20840 * exp_dist.adb: Add support for wide wide character type
20841 (Expand_Receiving_Stubs_Bodies): For a package declaration that has a
20842 private part, generate stub bodies at the end of the private part,
20843 not the visible part.
20844 (Add_RACW_Primitive_Operations_And_Bodies): Add last missing code for
20846 (Add_Obj_RPC_Receiver_Completion): Add PCS-specific subprograms and
20847 generic wrapper to execute final processing after completing the

21122 the formal subprogram.
21123 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
21124 which is an unclean use of that field, we set the new field

21143 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
21144 mark in function specification, in a context where the formals are
21145 visible and hide outer homographs.

21148 as the tagged type for the cases of abstract formal subprograms and
21149 renamings of those. Clean up spec comments.
21150 (Check_Dispatching_Context): Add error message to indicate "abstract
21151 procedure", covering the case of a call to a formal abstract procedure
21152 that has statically tagged operands.
21153 (Check_Dispatching_Call): Check for the case of an actual given by
21154 a tag-indeterminate function call whose type is an ancestor of the
21155 containing call's associated tagged type. This situation can occur
21156 for inherited primitives with function defaults. In this case we
21157 use the tagged type's tag directly as the controlling argument for

21336 * Makefile.in: Link all gnat tools with -static-libgcc, since
21337 -shared-libgcc is now used by default on some systems (e.g. linux with
21339 Remove references to Makefile.prolog/generic, no longer used.

21350 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
21351 with expansion disabled. The actual subtype is needed among other
21352 places when the selected component appears in the context of a loop
21353 bound, and denotes a packed array.
21354 (Operator_Check): Always use the first subtype in the
21355 error message, to avoid the appearance of internal base types.
21356 (Transform_Object_Operation): Copy each actual in full
21357 to the parameter associations of the constructed call, rather than
21358 using the shallow copy mechanism of New_Copy_List. This ensures that
21359 the chaining of named associations is done properly.
21360 (Complete_Object_Operation): Rewrite node, rather than
21361 replacing it, so that we can trace back to the original selected
21364 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
21365 and calls that use object notation, if the called function is not
21366 declared in a withed unit, place the elaboration constraint on the
21367 unit in the context that makes the function accessible.
21368 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
21369 imposes an elaboration constraint between two packages.
21371 2005-02-09 Ed Schonberg <schonberg@adacore.com>
21373 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
21374 views of a private type after handling its private dependents, to
21375 maintain proper stack discipline between entry and exit from the
21378 2005-02-09 Cyrille Comar <comar@adacore.com>
21380 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

21396 Slight fix to documentation of -gnaty with no parameters
21398 * xr_tabls.ads: Add ??? comment for missing overall comment
21400 * xsinfo.adb: Make default file name be sinfo.h, since this is what
21401 we now use by default.
21403 * xsnames.adb: Adjust end of file test to look for five space followed
21404 by '#' instead of six spaces. The format of xsnames.adb was modified
21405 in the last update.
21407 * a-numeri.ads: Add reference to AI-388 for greek letter pi
21410 * clean.adb: Minor reformatting.
21412 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
21413 gnatname.adb: Minor reformatting
21414 Add 2005 to copyright output when utility is run
21416 * csets.adb: Eliminate obsolete comment
21418 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
21421 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
21423 2005-02-09 Sergey Rybin <rybin@adacore.com>
21425 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
21426 the difference between compact and incompact layout and add the record
21427 representation clause to the example illustrating different layouts.
21428 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
21429 component clauses").
21431 2005-02-09 Florian Villoing <villoing@adacore.com>
21433 * gnat_ugn.texi: Fix typos.
21434 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
21436 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
21437 in the generated documentation.
21439 2005-02-09 Arnaud Charlet <charlet@adacore.com>
21441 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
21443 Update linker wrapper when linking with non GNU C++.
21445 2005-02-09 Pascal Obry <obry@adacore.com>
21448 Document the procedure to debug the DllMain routine on Windows.
21449 Add note about -funwind-tables and mixed Ada and C/C++ programming in

21481 * exp_util.ads: Minor correction in comment.
21483 2005-02-09 Arnaud Charlet <charlet@adacore.com>
21485 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
21486 since this procedure is now too complex to be worth inlining.
21488 2005-02-09 Richard Henderson <rth@redhat.com>
21490 * utils.c (gnat_define_builtin): Remove.
21491 (gnat_install_builtins): Use build_common_builtin_nodes.

21733 2005-01-03 Olivier Hainque <hainque@adacore.com>
21735 * decl.c (compatible_signatures_p): New function. The intended purpose
21736 is to check if two function signatures for a call-site and a callee are
21737 compatible enough for the call to be valid. The underlying purpose is
21738 to check if a call to a mapped builtin is using the right interface.
21739 The current code actually does not check antyhing - this a placeholder
21740 for future refinements.

21789 variants of the PCS.
21790 Reorganise RPC receiver generation to reduce differences between the
21791 structure of GARLIC and PolyORB RPC receivers.
21792 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
21794 Simplify elaboration code for RCI packages.
21796 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver
21797 generation to reduce differences between the structure of GARLIC and
21798 PolyORB RPC receivers.
21800 * s-stratt.adb: Fix typo in comment.

22160 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
22161 dereference is rewritten to an explicit one, generate a reference to

22279 used to record an implicit dereference as a read operation on its
22280 prefix when operating under -gnatc. Necessary to avoid spurious
22281 'variable assigned but never read' warnings in that mode.
22282 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
22283 is a non-overloaded implicit dereference, call the above subprogram to
22284 ensure proper recording of references.
22286 2004-12-07 Gary Dismukes <dismukes@adacore.com>
22288 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

22327 Sergey Rybin <rybin@adacore.com>
22329 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
22330 Files" with the new tool and package names.
22331 Reformatting to suppress most of the warnings for line too long
22332 Document the new section "Project Search Path:" in the output of
22334 Add gnatmetric section
22336 2004-12-07 Vincent Celier <celier@adacore.com>
22338 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
22339 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
22340 and -eit to -ept. Added qualifier
22341 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
22343 2004-11-27 Andreas Schwab <schwab@suse.de>
22345 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
22347 2004-11-25 Arnaud Charlet <charlet@adacore.com>
22349 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
22350 internal implementation unit GNAT.Sockets.Thin,
22351 as their usage for sockets is non-portable (using the read and write
22352 functions from the system runtime library is fine on UNIX but won't
22353 work under Windows).
22355 * mingw32.h: Update copyright notice.
22357 2004-11-25 Arnaud Charlet <charlet@adacore.com>
22359 * ada-tree.h: Minor reformatting of previous change to avoid lines
22360 longer than 79 characters.
22362 2004-11-25 Olivier Hainque <hainque@adacore.com>
22364 * tb-gcc.c: GCC infrastructure based implementation of

22378 2004-11-21 Andreas Jaeger <aj@suse.de>
22380 * stylesw.adb: Change Style_Check_Subprogram_Order to
22381 Style_Check_Order_Subprograms.
22383 2004-11-18 Arnaud Charlet <charlet@adacore.com>
22385 * adaint.h, adaint.c
22386 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
22388 Add also a cast to kill another warning.
22389 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
22390 parameter with the priority class of the parent process instead of
22391 always using the NORMAL_PRIORITY_CLASS.
22392 (__gnat_dup): New function.
22393 (__gnat_dup2): New function.
22394 (__gnat_is_symbolic_link): Enable the effective body of this
22395 function when __APPLE__ is defined.
22397 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
22400 2004-11-18 Olivier Hainque <hainque@adacore.com>
22402 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
22403 address of which may be used to represent "others" and "all others"
22404 choices in exception tables, instead of the current harcoded
22405 (void *)0 and (void *)1.
22406 (Setup_Exception): Do nothing in the GNAT SJLJ case.
22408 * gigi.h (others_decl, all_others_decl): New decls representing the
22409 new Others_Value and All_Others_Value objects.
22410 (struct attrib): Rename "arg" component as "args", since GCC expects a
22411 list of arguments in there.
22413 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
22414 corresponding objects exported by a-exexpr, instead of hardcoded dummy
22417 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
22418 others_decl and all_others_decl instead of hardcoded dummy addresses
22419 to represent "others" and "all others" choices, which is cleaner and
22420 more flexible with respect to the possible eh pointer encoding policies.
22422 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
22423 (process_attributes): Account for the naming change of the "args"
22424 attribute list entry component.
22426 * decl.c (build_attr_list): Rename into prepend_attributes to allow
22427 cumulating attributes for different entities into a single list.
22428 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
22429 attributes for the current entity and propagate first subtype
22430 attributes to other subtypes.
22431 <E_Procedure>: Attribute arguments are attr->args and not
22432 attr->arg any more.
22433 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
22434 argument provided, as this is what GCC expects. Use NULL_TREE instead
22437 2004-11-18 Robert Dewar <dewar@adacore.com>
22439 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
22440 Minor reformatting througout (including new function specs)
22441 Add ??? comments asking for clarification.
22443 2004-11-18 Thomas Quinot <quinot@adacore.com>
22445 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
22446 incomplete duplicate implementation of this subprogram from butil.
22448 2004-11-18 Thomas Quinot <quinot@adacore.com>
22450 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
22451 procedures factors the common processing for building an RPC receiver
22452 for an RCI package or an RACW type.
22453 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
22454 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
22455 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
22457 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
22459 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
22461 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
22462 distribution subprogram identifiers that are either subprogram numbers
22464 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
22465 string distribution identifiers assigned to a given subprogram.
22466 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
22467 (Add_RAS_Dereference_TSS): Add comments.
22468 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
22469 is not referenced yet because it will be used by the PolyORB DSA
22471 (Insert_Partition_Check): Remove fossile code.
22472 (First_RCI_Subprogram_Id): Document this constant.
22473 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
22475 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
22476 replaced with calls to Get_Library_Unit_Name_String. Previously there
22477 were several instances of the same code in different locations in the
22478 compiler; this checkin completes the replacement of all of these
22479 instances with calls to a common subprogram.
22480 Minor reformatting.
22482 * sem_dist.adb: Remove comment noting that RPC receiver generation
22483 should be disabled for RACWs that implement RASs.
22484 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
22486 * sem_util.ads, sem_util.adb (Has_Stream): New function
22487 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
22488 qualified name of a library unit into the name buffer.
22489 (Note_Possible_Modification): Generate a reference only
22490 if the context comes from source.
22492 * snames.ads (PCS_Names): New subtype corresponding to names of
22493 supported implementations of the Partition Communication Subsystem
22494 (PCS) (i.e. the runtime library support modules for the distributed
22497 2004-11-18 Robert Dewar <dewar@adacore.com>
22498 Ed Schonberg <schonberg@adacore.com>
22500 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
22501 (Has_Rep_Pragma): New function
22502 (Has_Attribute_Definition_Clause): New function
22503 (Record_Rep_Pragma): Moved here from sem_ch13.adb
22504 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
22506 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
22508 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
22509 (Expand_Pragma_Psect_Object): New procedure
22510 These procedures contain the revised and cleaned up processing for
22511 these two pragmas. This processing was formerly in Sem_Prag, but
22512 is more appropriately moved here. The cleanup involves making sure
22513 that the pragmas are properly attached to the tree, and that no
22514 nodes are improperly shared.
22516 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
22517 pragmas to Exp_Prag, which is more appropriate.
22518 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
22519 check for duplicates Remove use of Is_Psected flag, no longer needed.
22520 Use new Make_String_Literal function with string.
22522 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
22523 that are functions return universal values, that have to be converted
22524 to the context type.
22525 Use new Make_String_Literal function with string.
22526 (Get_Stream_Convert_Pragma): New function, replaces the use of
22527 Get_Rep_Pragma, which had to be kludged to work in this case.
22529 * freeze.adb: Use new Has_Rep_Pragma function
22531 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
22532 function with string.
22533 Use new Has_Rep_Pragma function.
22535 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
22538 2004-11-18 Robert Dewar <dewar@adacore.com>
22540 * errout.ads, errout.adb: (First_Sloc): New function
22542 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
22543 check (-gnatyx) instead of being included as a redundant construct
22546 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
22547 Style_Check_Order_Subprograms.
22549 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
22550 stylesw.adb: Add Style_Check_Xtra_Parens
22552 * usage.adb: Add line for -gnatyx (check extra parens)
22554 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
22556 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22557 Robert Dewar <dewar@adacore.com>
22559 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
22560 discriminant of a constrained subtype, analyze the copy of the
22561 corresponding constraint, because in some cases it may be only
22562 partially analyzed.
22563 Removes long-lived ??? comments.
22565 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
22566 handled controlled or secondary-stack expressions within the
22567 iteration_scheme of a loop.
22569 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
22570 bounds that may contain functions calls, to prevent memory leaks when
22571 the bound contains a call to a function that uses the secondary stack.
22572 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
22573 generate temporaries for loop bounds that might contain function calls
22574 that require secondary stack and/or finalization actions.
22576 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
22577 selected component and the selector is overloadable (not just a
22578 function) treat as function call, Analyze_Call will disambiguate if
22580 (Analyze_Selected_Component): Do not generate an actual subtype for the
22581 selected component if expansion is disabled. The actual subtype is only
22582 needed for constraint checks.
22583 (Analyze_Allocator): If restriction No_Streams is set, then do
22584 not permit objects to be declared of a stream type, or of a
22585 composite type containing a stream.
22587 * restrict.ads: Remove the a-stream entry from Unit_Array, since
22588 No_Streams no longer prohibits with'ing this package.
22590 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
22591 discriminants, but the parent base has unknown discriminants, there is
22592 no discriminant constraint to inherit. Such a discrepancy can arise
22593 when the actual for a formal type with unknown discriminants is a
22594 similar private type whose full view has discriminants.
22595 (Analyze_Object_Declaration): If restriction No_Streams is set, then
22596 do not permit objects to be declared of a stream type, or of a
22597 composite type containing a stream.
22599 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22601 * exp_dbug.ads: Update documentation to reflect simpler encoding for
22602 protected operations.
22604 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
22605 generated name, it complicates decoding in gdb and hinders debugging
22606 of protected operations.
22607 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
22608 flag for the protected entry barrier function.
22609 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
22610 flag for the protected entry function.
22612 2004-11-18 Nicolas Setton <setton@adacore.com>
22614 * expect.c: Define __unix__ when __APPLE__ is defined.
22616 * Makefile.in: Inform the value of the variable GMEM_LIB in the
22617 Darwin-specific section.
22619 * lang-specs.h: Change the placement of the %1 marker.
22620 Works around the fact that gcc adds -fPIC by default under Darwin.
22622 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22624 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
22625 type of the object with the packed array type, set the Analyzed flag
22626 on the object if it is an entity or simple indexed component, to avoid
22627 spurious type errors.
22629 2004-11-18 Gary Dismukes <dismukes@adacore.com>
22631 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
22632 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
22633 separate line from the version message.
22635 2004-11-18 Ed Falis <falis@adacore.com>
22637 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
22639 (init_float): Eliminate initialization of floating point status for
22640 AE653. The instructions have no effect for vThreads.
22642 2004-11-18 Vincent Celier <celier@adacore.com>
22644 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
22645 gnatbind is invoked with -shared.
22647 2004-11-18 Jose Ruiz <ruiz@adacore.com>
22649 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
22650 for Detect_Blocking which is redundant with the check done within the
22651 procedure Protected_Single_Entry_Call.
22652 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
22653 Detect_Blocking which is redundant with the check done within the
22654 procedure Protected_Single_Entry_Call.
22656 2004-11-18 Vincent Celier <celier@adacore.com>
22658 * makegpr.adb (Compile): Put the compiling switches (in package
22659 Compiler and on the command line) immediately after "-c", instead of
22660 at the end of the command line invocation of the compiler, when
22661 compiling a non-Ada file.
22662 (Build_Global_Archive): When there is no need to rebuild the archive,
22663 set Global_Archive_Exists, so that the archive is passed to the linker
22666 2004-11-18 Robert Dewar <dewar@adacore.com>
22667 Sergey Rybin <rybin@adacore.com>
22670 Remove extra paren check from list of checks for redundant constructs
22671 Add documentation of new -gnatyx style check (check extra parens)
22672 Remove paragraph about gnatelim debug options.
22674 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
22675 objects rather than forbidding dependencies on the package Ada.Streams.
22677 * sinfo.ads: Add ??? note that we should document pragmas passed to
22680 * g-expect.ads: Fix a few typos in the comments.
22682 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
22684 * misc.c (gnat_handle_option): Use %< and %> for quoting in
22687 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
22689 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
22691 2004-11-07 Andreas Schwab <schwab@suse.de>
22693 * Makefile.in (install-gnatlib): Remove spurious hyphen.
22695 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
22698 * Makefile.in (darwin): Set soext to .dylib.
22700 2004-10-26 Vincent Celier <celier@gnat.com>
22701 Thomas Quinot <quinot@act-europe.fr>
22703 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
22704 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
22705 there is no use of GNAT.Sockets.Constants.
22706 Remove remaining pragma Import for C_Write
22707 Remove C_Read and C_Write from internal implementation unit
22708 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
22709 the read and write functions from the system runtime library is fine
22710 on UNIX but won't work under Windows).
22712 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
22713 (Check_Selector): Use C_Recv instead of C_Read.
22714 Selectors are the GNAT.Sockets abstraction to perform a select()
22715 call on a set of descriptors. To allow abortion of an ongoing
22716 select operation, some data is written to a dedicated socket that
22717 is always monitored.
22718 Under Windows, the write and read library functions cannot operate
22719 on sockets, so we need to use send and recv instead, which is portable
22720 across all supported platforms.
22722 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
22723 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
22724 (using the read and write functions from the system runtime library is
22725 fine on UNIX but won't work under Windows).
22727 2004-10-26 Nicolas Setton <setton@act-europe.fr>
22729 * mlib-tgt-darwin.adb: New file.
22731 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
22732 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
22733 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
22734 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
22737 * Makefile.in: Add support for building shared libraries under Darwin.
22738 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
22739 the low level EH init subprogram to be called from __gnat_initialize.
22741 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
22742 indicates which options to pass to the archive indexer.
22744 * mlib-utl.adb: Add support for calling ranlib with additional
22745 options. This is needed for instance under Mac OS X.
22746 (Ranlib_Options): New global variable, used to store the potential
22747 options to pass to ranlib.
22748 (Ar): Use Ranlib_Options when spawning ranlib.
22749 (Initialize): Set the value of ranlib option.
22751 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
22753 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
22754 instead of 8K, to reflect the real potential needs for stack-checking
22757 2004-10-26 Pascal Obry <obry@gnat.com>
22759 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
22761 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
22762 Windows only the initial thread stack size can be set so it is good to
22763 start we a low stack size.
22764 The OS will adjust the size as needed.
22766 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
22767 Nicolas Setton <setton@act-europe.fr>
22769 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
22770 "__unix__" instead of "unix".
22771 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
22772 sections were just mistakenly ignored. The former is
22773 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
22774 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
22775 of hpux. This prevents an unwanted definition of the symbol
22776 convert_addresses in adaint.o.
22778 2004-10-26 Gary Dismukes <dismukes@gnat.com>
22780 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
22781 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
22783 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22785 * a-filico.ads, a-filico.adb: fix incorrect header.
22787 2004-10-26 Javier Miranda <miranda@gnat.com>
22789 * a-ststio.ads: Fix typo in identifier
22791 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22793 * sem_ch4.adb: Minor reformatting.
22795 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22797 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
22798 enabled, check the result of unary and binary operations when the
22799 expression is the right-hand side of an assignment.
22801 2004-10-26 Vincent Celier <celier@gnat.com>
22803 * clean.adb (Delete): Do not output warnings when in quiet output and
22804 not in verbose mode.
22805 (Force_Deletions): New Boolean flag, defaulted to False
22806 (Delete): Only delete a file if it is writable, and when
22807 Force_Deletions is True.
22808 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
22809 (Usage): Line for new switch -f
22810 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
22813 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
22815 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
22816 JM type only if its size matches that of the wrapper. When a size is
22817 prescribed and the field is not aliased, remove the wrapper of a JM
22818 type only if the size is not greater than that of the packed array.
22819 (gnat_to_gnu_entity): Change the extension of packed array wrappers
22822 2004-10-26 Geert Bosch <bosch@gnat.com>
22824 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
22825 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
22826 (Pred): Implement in terms of Succ.
22828 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22830 * exp_aggr.adb (Safe_Component): An aggregate component that is an
22831 unchecked conversion is safe for in-place use if the expression of the
22832 conversion is safe.
22833 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
22834 be expandable in place even if the aggregate does not come from source.
22835 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
22836 designated object of an allocator in place, rather than building it
22837 first on the stack. The previous scheme forces a full copy of the array,
22838 and may be altogether unsusable if the size of the array is too large
22839 for stack allocation.
22841 2004-10-26 Robert Dewar <dewar@gnat.com>
22843 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
22844 compares if the component is atomic.
22846 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
22847 array assignment if the component type is atomic.
22849 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22850 Eric Botcazou <ebotcazou@act-europe.fr>
22852 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
22853 is aliased and is a by_reference type, do not pass by copy.
22854 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
22855 detect whether the call is in the right side of an assignment or
22856 the expression of an object declaration. Recurse on component
22857 association within aggregates.
22858 Call it in the condition that determines whether the temporary is
22859 necessary for correct stack-checking.
22861 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22863 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
22864 RACW_Type, used in the PolyORB version.
22865 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
22866 version and the GARLIC version.
22868 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
22869 Rename RCI_Info to RCI_Locator for better consistency between the
22870 GARLIC and PolyORB versions of the distributed systems annex.
22871 (DSA_Implementation_Name): This enumeration lists the possible
22872 implementations of the Partition Communication Subsystem for the
22873 Distributed Systems Annex (DSA). The three available implementations
22874 are the dummy stub implementation (No_DSA), and two versions based on
22875 two different distribution runtime libraries: GARLIC and PolyORB. Both
22876 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
22878 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
22881 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
22882 between the GARLIC and PolyORB versions of the distributed systems
22884 Remove RE_Unbounded_Reclaim_Pool since it is unused.
22886 2004-10-26 Gary Dismukes <dismukes@gnat.com>
22888 * gnat1drv.adb: Suppress calling the back end when
22889 Frontend_Layout_On_Target is true.
22891 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22893 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
22894 Set_Read_Only): New subprograms.
22895 These new routines allow the user to set or unset the Owner execute
22896 and Owner write permission flags on a file.
22898 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
22899 GNAT.OS_Lib.Set_Executable instead of rolling our own.
22901 2004-10-26 Matthew Gingell <gingell@gnat.com>
22903 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
22905 2004-10-26 Pascal Obry <obry@gnat.com>
22907 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
22908 memory before the faulting page we properly test the process read
22909 access for this address using appropriate Win32 routine.
22910 (HPUX sections): guard with "__hpux__" instead of "hpux".
22912 2004-10-26 Robert Dewar <dewar@gnat.com>
22914 * lib-xref.adb (Generate_Reference): Don't complain about reference to
22915 entry parameter if pragma Unreferenced set, since we do not properly
22916 handle the case of multiple parameters.
22918 2004-10-26 Vincent Celier <celier@gnat.com>
22920 * prj-env.adb: (Contains_ALI_Files): New Boolean function
22921 (Ada_Objects_Path.Add): For a library project, add to the object path
22922 the library directory only if there is no object directory or if the
22923 library directory contains ALI files.
22924 (Set_Ada_Paths.Add.Recursive_Add): Ditto
22926 2004-10-26 Vincent Celier <celier@gnat.com>
22928 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
22929 extension of library projects.
22931 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
22932 path defaults to ".:<prefix>/lib/gnat".
22933 (Parse): For an extending all project, allow direct import of a project
22934 that is virtually extended.
22936 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
22937 the specified name is directly imported, return its ID. Otherwise, if
22938 an extension of this project is imported, return the ID of the
22941 2004-10-26 Robert Dewar <dewar@gnat.com>
22943 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
22944 (Sub3): New procedure, used by Scaled_Divide
22945 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
22946 correct more than one instance of failure to propagate carries
22948 (Double_Divide): Handle overflow case of largest negative number
22949 divided by minus one.
22951 * s-arit64.ads (Double_Divide): Document that overflow can occur in
22952 the case of a quotient value out of range.
22955 2004-10-26 Robert Dewar <dewar@gnat.com>
22957 * s-bitops.adb (Bit_Eq): Remove redundant check.
22959 * s-bitops.ads: Minor comment updates
22960 Change some occurrences of Address to System.Address
22962 * s-carsi8.ads: Fix minor cut-and-paste error in comments
22964 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22966 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
22967 accessibility check to prefix that is a protected operation.
22969 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22971 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
22972 empty, post message on stub.
22974 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22975 Javier Miranda <miranda@gnat.com>
22977 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
22978 current instance appears within a unit that is directly in the context
22980 Used to determine whether the body of the instance should be analyzed
22981 immediately after its spec, to make its subprogram bodies available
22982 for front-end inlining.
22983 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
22984 constraint is not allowed on the component type (AARM 12.5.3(3))
22986 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22988 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
22989 'Storage_Pool): enhance, document & limit detection of non-sharable
22992 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
22994 * s-pooglo.ads: Add more documentation now that this pool is properly
22997 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22999 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
23000 or protected type with discriminants, do not constrain the
23001 corresponding record type if the subtype declaration has no
23002 discriminant constraints. This can be the case in source code, or in
23003 the subtype declaration created to rename an actual type within an
23006 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23008 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
23009 different kind of stub (possibly wrong name for file), do not check
23011 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
23012 includes call to some function that returns an unconstrained type, do
23015 2004-10-26 Ed Schonberg <schonberg@gnat.com>
23017 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
23018 appear in the code for the main unit. Dependencies among units in the
23019 context of the main unit are established when those other units are
23020 compiled. Otherwise spurious elaboration constraints can generate
23021 incorrect elaboration circularities.
23023 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
23024 Ed Schonberg <schonberg@gnat.com>
23026 * sem_util.adb (Is_Aliased_View): Defend against the case where this
23027 subprogram is called with a parameter that is not an object name. This
23028 situation arises for some cases of illegal code, which is diagnosed
23029 later, and in this case it is wrong to call Is_Aliased, as that might
23030 cause a compiler crash.
23031 (Explain_Limited_Type): Refine previous fix to include
23032 inherited components of derived types, to provide complete information.
23034 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
23035 is the prival for a protected object.
23036 It is necessary to mark this entity as a variable, in addition to
23037 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
23038 modified to avoid checking the Aliased flag on entities that are not
23039 objects. (Checking that flag for non-objects is erroneous and could
23040 lead to a compiler crash).
23042 2004-10-26 Robert Dewar <dewar@gnat.com>
23044 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
23045 X_Frac = 0.5, then we know that the number X must be positive.
23046 (Succ): Remove the same redundant test, and also fix the primary test
23047 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
23049 (Decompose): Add fuller comments to spec
23051 2004-10-26 Pascal Obry <obry@gnat.com>
23053 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
23054 validity (process must have read access). Set to 0 in all other cases.
23055 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
23056 violation on Win32.
23057 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
23058 segmentation violation.
23060 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
23062 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
23063 whose type is a constructed subtype of an aliased object with an
23064 unconstrained nominal subtype, convert the actual to the constructed
23065 subtype before taking its address.
23067 2004-10-26 Vincent Celier <celier@gnat.com>
23069 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
23070 (Is_Path_Name_Case_Sensitive): New function
23072 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
23073 (Base_Name, Simple_Name, Current_Directory, Compose,
23074 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
23077 2004-10-26 Cyrille Comar <comar@act-europe.fr>
23078 Vasiliy Fofanov <fofanov@act-europe.fr>
23079 Vincent Celier <celier@gnat.com>
23081 * gnat_ugn.texi: Generalize "finding memory problems" section into a
23082 "memory management issues" section and document some of the useful
23083 memory pools provided as part of the GNAT library.
23084 Remove "virtual" from declaration of A::method2 in
23085 the simple example of Ada/C++ mixed system.
23086 Library Projects may be virtually extended: their virtual extensions
23087 are not Library Projects.
23088 Added section on extending project hierarchies.
23090 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
23092 * adaint.c (__gnat_get_libraries_from_registry): Cast value
23094 (__gnat_portable_spawn): Remove const.
23096 * mingw32.h (MAXPATHLEN): Check for previous definition.
23098 2004-10-17 Matthias Klose <doko@debian.org>
23100 * gnatvsn.ads: Set gnat library version to 4.0.
23102 2004-10-05 Vincent Celier <celier@gnat.com>
23104 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
23106 2004-10-04 Laurent GUERBY <laurent@guerby.net>
23109 * Makefile.in: Define and use RANLIB_FLAGS.
23111 2004-10-04 Pascal Obry <obry@gnat.com>
23113 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
23114 other x86 platforms).
23116 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
23118 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
23119 in general and triggers stack alignment adjustment for thread entry
23120 points on targets where this is necessary.
23122 2004-10-04 Bernard Banner <banner@gnat.com>
23125 * Makefile.in: Add section for powerpc linux
23126 Add variant i-vxwork-x86.ads
23128 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
23130 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
23132 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
23133 table registration calls when need be. Ensures no reference to the crt
23134 ctors symbol are issued in the SJLJ case, which avoids possible
23135 undefined symbol errors in the case of modules to be statically linked
23138 2004-10-04 Javier Miranda <miranda@gnat.com>
23140 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
23141 in-line the code corresponding to subprogram Analyze_Actuals. In
23142 addition, analyze the actuals only in case of subprogram call.
23144 2004-10-04 Ed Falis <falis@gnat.com>
23146 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
23148 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
23150 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
23151 in the documentation.
23153 2004-10-04 Robert Dewar <dewar@gnat.com>
23155 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
23157 (Analyze_Block_Statement): Add circuitry to detect following dead code
23158 (Check_Unreachable_Code): Handle case of block exit
23160 2004-10-04 Robert Dewar <dewar@gnat.com>
23162 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
23163 (XMatchD): Avoid warning for Logic_Error call
23165 2004-10-04 Robert Dewar <dewar@gnat.com>
23167 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
23168 consider expressions buried within a procedure actual to be an actual.
23169 This caused some blowups with uses of packed slices within a procedure
23172 2004-10-04 Robert Dewar <dewar@gnat.com>
23174 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
23175 longer need to be initialized to zero.
23176 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
23177 initialized to zero.
23179 * checks.adb (Expr_Known_Valid): Packed arrays are now always
23180 considered valid, even if the representation is modular. That's correct
23181 now that we no longer initialize packed modular arrays to zero.
23183 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
23184 suffixes. These are now documented as the only cases in which the
23185 debugger ignores outer records.
23186 Previously, the spec allowed arbitrary suffixes for this purpose.
23187 Change name of LJM to JM for packed array pad records
23188 Create separate section on packed array handling, and add a whole new
23189 set of comments to this section describing the situation with packed
23190 modular types and justification requirements depending on endianness.
23192 2004-10-04 Robert Dewar <dewar@gnat.com>
23194 * a-except.adb: Add a comment for last change

23203 * sem_util.ads: Minor comment update
23205 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23207 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
23208 Inline_Always when in Configurable_Run_Time mode.
23210 * sem_prag.adb (Process_Convention): If entity is an inherited
23211 subprogram, apply convention to parent subprogram if in same scope.
23212 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
23213 when in Configurable_Run_Time mode.
23215 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23217 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
23218 class_wide type after component list has been inherited.
23220 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23222 * sem_ch12.adb (Check_Generic_Actuals): New predicate
23223 Denotes_Previous_Actual, to handle properly the case of a private
23224 actual that is also the component type of a subsequent array actual.
23225 The visibility status of the first actual is not affected when the
23226 second is installed.
23227 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
23228 make fully recursive the treatment of formals of packages declared
23230 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
23231 the above on exit from an instantiation.
23232 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
23233 current instantiation which is now complete.
23234 (Analyze_Package_Instantiation): No instantiated body is needed if the
23235 main unit is generic. Efficient, and avoid anomalies when a instance
23236 appears in a package accessed through rtsfind.
23238 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23240 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
23241 do not generate a declaration for a temporary if the call is part of a
23242 library-level instantiation.
23244 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23246 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
23247 searching for a limited component to flag.
23249 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
23250 expansion of Input, to account for the fact that the implicit call
23251 generated by the attribute reference must freeze the user-defined
23252 stream subprogram. This is only relevant to 'Input, because it can
23253 appear in an object declaration, prior to the body of the subprogram.
23255 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
23256 expansion can proceed and further errors uncovered.
23257 (Minor clean up): Fix cases of using | instead of \ for continuation
23260 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

23268 * decl.c (gnat_to_gnu_entity, case object): Check and process a
23269 specified alignment before validating size.
23270 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
23271 stripped-down declaration for the type of the inner field when making
23274 * utils.c (finish_record_type): Do not compute the size in units
23275 incrementally. Instead compute it once for the rep clause case.
23276 Use gcc_assert and gcc_unreachable.
23278 2004-10-04 Vincent Celier <celier@gnat.com>
23280 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
23282 (Is_Valid_Path_Name): Take '/' as a directory separator.
23284 2004-10-04 Vincent Celier <celier@gnat.com>
23286 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
23287 (Extended_Project) only if Extended_Project is defined, to avoid
23289 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
23291 (Parse_Single_Project): Ditto.
23293 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
23294 Add_To_Project_Path for virtual projects.
23296 2004-10-04 Vincent Celier <celier@gnat.com>
23298 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
23299 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
23300 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
23301 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
23302 parameter Options_2.
23304 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
23305 Build_Dynamic_Library with an empty Options_2.
23307 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
23310 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
23311 directory separator, if any.
23312 (Gprmake): Do not allow mains on the command line for library projects.
23313 Do not attempt to link when the project is a library project.
23314 (Library_Opts): New table to store Library_Options.
23315 (Build_Library): If Library_Options is specified, pass these options
23316 when building a shared library.
23318 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
23320 * s-tposen.adb (Service_Entry): The object must be always unlocked at
23321 the end of this procedure now that the unlock operation was inserted
23324 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
23326 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
23327 corresponding to the Preallocated_Stacks flags in System.
23328 (Get_Target_Parameters): Including the processing for

23340 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
23341 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
23342 used to signal whether the compiler creates the required stacks and
23343 descriptors for the different tasks (when True) or it is done by the
23344 underlying operating system at run time (when False).
23345 It is initially set to False in all targets.
23347 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
23348 if it is supported by the target.
23349 (Make_Task_Create_Call): Pass the stack address if it has been
23350 previously created. Otherwise pass a Null_Address.
23352 * snames.adb: Add _stack.
23354 * snames.ads: Add Name_uStack. Required to allow the expander to
23355 statically allocated task stacks.
23357 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
23358 Stack_Address argument.
23359 Check that its value is equal to Null_Address because this target does
23360 not support the static stack allocation.

23369 * exp_dist.adb: Split declaration of asynchronous flag out of
23370 Add_RACW_Read_Attribute.
23371 Minor reformatting for better alignment with PolyORB version.
23372 Store the entity for the asynchronous flag of an RACW, rather than the
23373 expression, in the asynchronous flags table. This will allow this flag
23374 to be used in other subprograms beside Add_RACW_Read_Attribute.

23383 sockets constant MSG_NOSIGNAL (Linux-specific).
23384 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
23385 all Send operations.
23386 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
23387 from trigerring SIGPIPE.
23388 Rename components to avoid clash with Ada 2005 possible reserved

23405 Minor reformatting.
23407 * freeze.adb (Check_Address_Clause): Remove previous change, not the
23408 right way of doing things after all.
23409 (Freeze_Entity): For object, set Is_Public for imported entities
23410 unless there is an address clause present.
23412 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
23414 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
23415 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
23416 ensures proper handling of types with rep clauses, which might have
23417 their TYPE_SIZE set already.
23419 2004-09-21 Robert Dewar <dewar@gnat.com>
23421 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
23422 packed array types in both little- and big-endian cases. This change
23423 ensures that we no longer count on the unused bits being initialized
23424 for such types (and in particular ensures that equality testing will
23425 only read the relevant bits).
23426 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
23427 These changes mean that we no longer need to initialize small packed
23429 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
23430 optimization to an LJM field as to its parent field.
23432 * ada-tree.h, trans.c, utils.c, utils2.c:

23476 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
23477 Convert the result to File_Size.
23479 * prj.ads: (Project_Error): New exception
23481 * prj-attr.adb: Except in procedure Initialize, Fail comes from
23482 Prj.Com, not from Osint.

23487 Prj.Project_Error after call to Fail.
23488 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
23489 Fail. Check that package name is not already in use.
23491 * prj-attr.ads: Comment updates to indicate that all subprograms may be
23492 used by tools, not only by the project manager, and to indicate that
23493 exception Prj.Prj_Error may be raised in case of problem.
23494 (Add_Unknown_Package, Add_Attribute): Moved to new child package
23496 (Attrs, Package_Attributes): Table instantiations moved from the body to
23497 the private part to be accessible from Prj.Attr.PM body.

23552 pragmas recognized by GNAT.
23554 * gnat_rm.texi: Document pragma Detect_Blocking.
23556 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
23557 raise Program_Error if called from a protected operation.
23559 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
23560 the protected action nesting level.
23561 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
23562 protected action nesting level.
23563 (Unlock): When pragma Detect_Blocking is active decrease the protected
23564 action nesting level.
23566 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
23567 Protected_Action_Nesting.
23569 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
23570 Common_ATCB record. It contains the dynamic level of protected action
23571 nesting for each task. It is needed for checking whether potentially
23572 blocking operations are called from protected operations.
23573 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
23574 Detect_Blocking is active or not in the partition.
23576 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
23577 raise Program_Error if called from a protected operation.

23590 Program_Error if called from a protected operation, and increase the
23591 protected action nesting level.

23606 protected action nesting level.
23608 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
23609 insertion of the statement raising Program_Error. The run time
23610 contains the required machinery for handling that.
23612 * sem_util.ads: Change comment associated to procedure
23613 Check_Potentially_Blocking_Operation.
23614 This procedure does not insert a call for raising the exception because
23615 that is currently done by the run time.
23617 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
23619 * init.c: Add the global variable __gl_detect_blocking that indicates
23620 whether pragma Detect_Blocking is active (1) or not (0). Needed for
23621 making the pragma available at run time.
23622 (__gnat_set_globals): Pass and update the detect_blocking parameter.
23624 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
23625 pragma Detect_Blocking is active.
23627 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
23629 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
23630 DB is found in the ali file. Any unit compiled with pragma
23631 Detect_Blocking active forces its effect in the whole partition.
23633 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
23634 Detect_Blocking is active and delay is called from a protected
23637 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
23638 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
23639 Detect_Blocking is active (0 otherwise).
23640 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
23641 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
23644 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
23646 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
23647 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
23650 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
23651 (Register_Receiving_Stub): Add Subp_Info formal parameter.
23652 Update API in placeholder implemetation of s-parint to reflect changes
23653 in distribution runtime library.
23655 * sem_ch3.adb (Expand_Derived_Record): Rename to
23656 Expand_Record_Extension.
23658 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
23659 primitive operations of potentially distributed object types that have
23660 non-controlling anonymous access formals.
23662 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
23664 New implementation of expansion for remote access-to-subprogram types,
23665 based on the RACW infrastructure.
23666 This version of sem_dist is compatible with PolyORB/DSA as well as
23669 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
23670 Asynchrronous that applies to a remote access-to-subprogram type, mark
23671 the underlying RACW type as asynchronous.
23673 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
23674 __gnat_using_gnu_linker to 1.
23676 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
23677 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

23683 * exp_ch3.adb (Expand_Derived_Record): Rename to
23684 Expand_Record_Extension.
23685 (Build_Record_Init_Proc.Build_Assignment): The default expression in
23686 a component declaration must remain attached at that point in the
23687 tree so New_Copy_Tree copies it if the enclosing record type is derived.
23688 It is therefore necessary to take a copy of the expression when building
23689 the corresponding assignment statement in the init proc.
23690 As a side effect, in the case of a derived record type, we now see the
23691 original expression, without any rewriting that could have occurred
23692 during expansion of the ancestor type's init proc, and we do not need
23693 to go back to Original_Node.
23695 * exp_ch3.ads (Expand_Derived_Record): Rename to
23696 Expand_Record_Extension.
23698 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
23699 Returns the RACW type used to implement a remote access-to-subprogram
23701 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
23702 New subprograms. Used to create a proxy tagged object for a remote
23703 subprogram. The proxy object is used as the designated object
23704 for RAS values on the same partition (unless All_Calls_Remote applies).
23705 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
23706 System.Partition_Interface.Get_Unique_Remote_Pointer.
23707 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
23708 Renamed from Add_RAS_*_Attribute.
23709 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
23711 New implementation of expansion for remote access-to-subprogram types,
23712 based on the RACW infrastructure.
23714 * exp_dist.ads (Copy_Specification): Update comment to note that this
23715 function can copy the specification from either a subprogram
23716 specification or an access-to-subprogram type definition.
23718 2004-09-09 Ed Schonberg <schonberg@gnat.com>
23720 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
23721 in an instance, between an explicit subprogram an one inherited from a
23722 type derived from an actual.
23724 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
23725 add a polling call if the subprogram is to be inlined by the back-end,
23726 to avoid repeated calls with multiple inlinings.
23728 * checks.adb (Apply_Alignment_Check): If the expression in the address
23729 clause is a call whose name is not a static entity (e.g. a dispatching
23730 call), treat as dynamic.
23732 2004-09-09 Robert Dewar <dewar@gnat.com>
23734 * g-trasym.ads: Minor reformatting
23736 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

23745 2004-09-09 Pascal Obry <obry@gnat.com>
23747 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
23748 enable map file generation. Add the right option to generate the map
23749 file if Map_File is set to True.
23751 * gnatdll.adb (Gen_Map_File): New variable.
23752 (Syntax): Add info about new -m (Map_File) option.
23753 (Parse_Command_Line): Add support for -m option.
23754 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

23780 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
23781 of variable length temporaries for function return now that the
23782 back-end and gigi support it.

23976 for a global aliased object with a variable size and an unconstrained
23977 nominal subtype, pretend there is no initializer if the one we have is
23978 incomplete, and avoid referencing an inexistant component in there. The

24006 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
24007 discriminants that rename those of the parent, recover names of

24070 ignore overflows on low and high bounds of an index to also account for
24071 differences in signedness between sizetype and gnu_index_subtype.
24072 These are as legitimate as the ones caused by a lower TYPE_PRECISION

27989 complete assignment subtree which is now unnecessary, as the expansion
27990 of inlined call has been improved to preserve a consistent assignment

27992 after checks have been applied, or else unnecessary checks will

28215 * sem_ch6.adb (Process_Formals): Carry out some static checks.
28216 (Set_Actual_Subtypes): Generate null-excluding subtype if the
28217 null-excluding part was present; it is not required to be done here in
28218 case of anonymous access types.
28219 (Set_Formal_Mode): Ada 0Y allows anonymous access to have the null
28222 * sem_res.adb (Resolve_Actuals): Carry out some static check
28223 (Resolve_Null): Allow null in anonymous access
28225 * sinfo.adb: New subprogram Null_Exclusion_Present
28226 All_Present and Constant_Present available on access_definition nodes
28228 * sinfo.ads: New flag Null_Exclusion_Present on subtype_declaration,
28229 object_declaration, derived_type_definition, component_definition,
28230 discriminant_specification, access_to_object_definition,
28231 access_function_definition, allocator, access_procedure_definition,
28232 access_definition, parameter_specification, All_Present and
28233 Constant_Present flags available on access_definition nodes.

28249 * sem_ch12.adb: Add comment for previous change
28251 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
28253 * osint.adb (Executable_Prefix): Set Exec_Name to the current
28254 executable name when not initialized. Otherwise, use its current value.
28256 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
28257 initialize it to another executable name than the current one. This
28258 allows to configure paths for an executable name (gnatmake) different
28259 from the current one (gnatdist).
28261 2004-03-29 Ed Schonberg <schonberg@gnat.com>
28263 * exp_ch6.adb (Expand_Call): A call to a function declared in the
28264 current unit cannot be inlined if it appears in the body of a withed
28265 unit, to avoid order of elaboration problems in gigi.
28267 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
28268 information for protected (wrapper) operation as well, to simplify gdb
28271 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
28272 protected body, indicate that the entity for the generated spec comes
28273 from source, to ensure that references are properly generated for it.
28274 (Build_Body_To_Inline): Do not inline a function that returns a
28277 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
28278 apply convention to homonyms that are declared explicitly.
28280 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
28281 that renames an equality operator and the operands are overloaded,
28282 resolve them with the declared formal types, before rewriting as an
28285 2004-03-29 GNAT Script <nobody@gnat.com>
28287 * Make-lang.in: Makefile automatically updated
28289 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
28291 * memtrack.adb: Log realloc calls, which are treated as free followed
28294 2004-03-25 Vincent Celier <celier@gnat.com>
28296 * prj-makr.adb (Process_Directories): Detect when a file contains
28297 several units. Do not include such files in the config pragmas or

28306 resolve links when computing the display names.
28308 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
28310 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
28311 attribute reference does not denote a subtype, it can be any
28312 expression that has a classwide type, potentially after an implicit
28313 dereference. In particular, the prefix can be a view conversion for
28314 a classwide type (for which Is_Object_Reference holds), but it can
28315 also be a value conversion for an access-to-classwide type. In the
28316 latter case, there is an implicit dereference, and the original node
28317 for the prefix does not verify Is_Object_Reference.
28319 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
28320 conversion of a discriminant-dependent component of a mutable object
28323 2004-03-25 Ed Schonberg <schonberg@gnat.com>
28325 * freeze.adb (Freeze_Entity): When an inherited subprogram is
28326 inherited, has convention C, and has unconstrained array parameters,
28327 place the corresponding warning on the derived type declaration rather
28328 than the original subprogram.
28330 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
28331 indication on renaming declaration, if formal has a box and actual
28334 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
28335 determine whether to generate an implicit or explicit reference to
28336 the renamed entity.
28338 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
28339 subprogram renaming comes from a defaulted formal subprogram in an
28342 2004-03-25 Gary Dismukes <dismukes@gnat.com>
28344 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
28345 value expressions to ensure that calls within a component definition
28346 will be checked (since those are evaluated during the record type's
28349 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
28351 * s-tpobop.adb: Code clean up:
28352 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

28366 2004-03-22 Cyrille Comar <comar@act-europe.fr>
28368 * ali.ads: Fix Comment about Dynamic_Elab.
28370 * gnatls.adb (Output_Unit): Add output of many flags (Dynamic_Elab,
28371 Has_RACW, Is_Generic, etc.)
28372 (Output_Object, Gnatls): Take into account ALI files not attached to
28375 2004-03-22 Vincent Celier <celier@gnat.com>
28377 * gprep.adb: Change all String_Access to Name_Id
28378 (Is_ASCII_Letter): new function
28379 (Double_File_Name_Buffer): New procedure
28380 (Preprocess_Infile_Name): New procedure
28381 (Process_Files): New procedure
28382 (Gnatprep): Check if output and input are existing directories.
28383 Call Process_Files to do the real job.

28390 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
28392 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
28393 case when the source contains only comments.
28395 2004-03-22 Ed Schonberg <schonberg@gnat.com>
28397 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
28398 declaration for a child subprogram body that acts as a spec, indicate
28399 that the entity in the declaration needs debugging information.
28401 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
28402 full view if the subtype is created for a constrained record component;
28403 gigi has enough information to construct the record, and there is no
28404 place in the tree for the declaration.
28406 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
28407 serial number for the dummy body that is built for analysis, to avoid
28408 inconsistencies in the generation of internal names when compiling
28411 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
28413 * sem_util.adb (Is_Object_Reference): A view conversion denotes an

28438 * gnat_ug.texi: Add info directory category and entry.
28439 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
28440 gnat_ug_wnt.texi: Regenerate.
28442 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
28444 * ada-tree.h: Update copyright notice.
28445 Minor reformatting.
28447 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
28449 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
28450 as regular exception objects and not as mere integers representing the
28451 condition code. The latter approach required some dynamics to mask off
28452 severity bits, which did not fit well into the GCC table based model.
28453 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
28454 exception data objects. We don't it and it would conflict with the other
28455 external symbol we have to generate for such exceptions.
28457 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
28458 the special code for VMS exceptions, since these are now represented
28459 as regular exceptions objects.
28461 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28463 * decl.c (debug_no_type_hash): Remove.

28465 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
28467 2004-03-19 Laurent Guerby <laurent@guerby.net>
28469 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
28470 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
28472 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28474 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
28475 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
28476 (TYPE_RM_SIZE_INT): Directly use type.values.
28477 (TREE_LOOP_ID): Clean up check.
28478 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
28479 TYPE_VALUES, not TYPE_FIELDS.
28480 * trans.c (convert_with_check): Delay access of bounds of basetype
28481 until sure is numeric.

28489 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
28490 Specific.Set instead of direct call to e.g pthread_setspecific.
28492 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
28494 * adaint.c: Update comments.
28496 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
28497 GNATLIB_SHARED for FreeBSD.
28499 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
28501 * init.c [VxWorks]: Do not fix the stack size for the environment task.
28502 When needed (stack checking) the stack size is retrieved
28503 from the VxWorks kernel.
28505 * Makefile.in: Flag -nostdinc is required when building the run time
28506 for avoiding looking for files in the base compiler.
28507 Add the VxWorks specific version of the package body for
28508 System.Stack_checking.Operations (5zstchop.adb).
28510 * Make-lang.in: Add the object file for
28511 System.Stack_Checking.Operations.
28513 * Makefile.rtl: Add object file for the package
28514 System.Stack_Checking.Operations.
28516 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
28518 * s-stache.ads, s-stache.adb: Move the operations related to stack
28519 checking from this package to package System.Stack_Checking.Operations.
28520 This way, stack checking operations are only linked in the final
28521 executable when using the -fstack-check flag.
28523 2004-03-18 Doug Rupp <rupp@gnat.com>
28525 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
28528 * 5qsystem.ads, 5xcrtl.ads: New files.
28530 2004-03-18 Vincent Celier <celier@gnat.com>

28534 * prj-env.adb (Source_Paths, Object_Paths): New tables.
28535 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
28536 the procedures Add_To_Path_File.
28537 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
28538 making sure that each directory is present only once and, for object
28539 dirs, when a directory already present is added, the duplicate is
28540 removed and the directory is always put as the last in the table.
28541 Write the path files at the end of these accumulations.
28543 * prj-nmsc.adb (Record_Source): Add source file name in hash table
28544 Files_Htable for all sources.
28546 * prj-proc.adb (Process): Remove restrictions between not directly
28547 related extending projects.
28549 2004-03-18 Emmanuel Briot <briot@act-europe.fr>

28555 parameter Trusted_Mode.
28557 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
28559 * scn.adb (Determine_License): Take into account a degenerated case
28560 when the source contains only comments.
28562 2004-03-18 Ed Schonberg <schonberg@gnat.com>
28564 * sem_warn.adb (Check_References): For a warning on a selected
28565 component that does not come from source, locate an uninitialized
28566 component of the record type to produce a more precise error message.
28568 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
28570 * 3zsoccon.ads: Fix multicast options.
28572 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
28575 2004-03-15 Robert Dewar <dewar@gnat.com>
28577 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
28578 pragma used for a private type.
28580 * lib-xref.adb (Generate_Reference): Do not generate warning if
28581 reference is in a different unit from the pragma Unreferenced.
28583 * 5vtpopde.adb: Minor reformatting
28584 Fix casing of To_Task_ID
28586 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
28587 flag if we have an unchecked conversion to an access type in the same
28590 2004-03-15 Geert Bosch <bosch@gnat.com>
28592 * a-ngcoty.adb (Modulus): In alternate formula for large real or
28593 imaginary parts, use Double precision throughout.
28595 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
28596 we want to be able to compile run-time with -gnata for testing, but
28597 this may also be instantiated in user code that is compiled with -gnata.
28599 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
28601 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
28602 codes. Having a separate type for this is useful to enforce consistency
28603 throughout the various run-time units.
28604 (Exception_Data): Use Exception_Code for Import_Code.
28606 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
28607 Natural and Integer in various places.

28609 with the severity bits masked off.
28610 (Register_VMS_Exception): Handle the additional exception data pointer
28613 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
28614 component, now reflected by an exported accessor.
28615 (is_handled_by): New routine to compute whether the propagated
28616 occurrence matches some handler choice specification. Extracted out of
28617 get_action_description_for, and expanded to take care of the VMS
28619 (get_action_description_for): Use is_handled_by instead of an explicit
28620 complex condition to decide if the current choice at hand catches the
28621 propagated occurrence.
28623 * raise.h (Exception_Code): New type for C.
28625 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
28626 System.Standard_Library.Exception_Code, to allow references from the
28627 pragma import/export expander.
28629 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
28630 New accessors to allow easy access to GNAT exception data
28632 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
28633 redundant Handled_By_Others component, helper for the personality
28634 routine which will now be able to call the appropriate exception data
28637 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
28638 component of Standard_Exception_Type to be the closest possible to
28639 Exception_Code in System.Standard_Library, that we cannot get at this
28640 point. Expand a ??? comment to notify that this type node should
28641 probably be rewritten later on.
28643 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
28644 registration call to include a pointer to the exception object in the
28647 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
28648 instead of int and explicit bitmasks.
28650 2004-03-15 Vincent Celier <celier@gnat.com>
28652 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
28653 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
28655 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
28656 longer needed now that it is in the spec of
28657 System.Tasking.Task_Attributes.
28659 * adaint.h, adaint.c: (__gnat_create_output_file): New function
28661 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
28663 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
28665 * make.adb (Gnatmake): Do not check the executable suffix; it is being
28666 taken care of in Scan_Make_Arg.
28667 (Scan_Make_Arg): Add the executable suffix only if the argument
28668 following -o, in canonical case, does not end with the executable
28669 suffix. When in verbose mode and executable file name does not end
28670 with executable suffix, output the executable name, in canonical case.
28672 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
28673 to avoid warnings when instantiating Ada.Task_Attributes.
28676 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
28677 in the correct order.
28679 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
28680 redirect standard output and error to a file for the invocation of the
28681 compiler, then read the file.
28683 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
28684 directory, instead of the Value.
28685 (Find_Source_Dirs): Remove useless code & comments.
28687 2004-03-15 Ed Schonberg <schonberg@gnat.com>
28689 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
28690 tagged type is inherited, and the parent operation is not frozen yet,
28691 force generation of a freeze node for the inherited operation, so the
28692 corresponding dispatch entry is properly initialized.
28693 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
28694 when looking for user-defined equality operation.
28696 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
28697 boolean when locating primitive equality of tagged component.
28699 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
28700 bit-aligned field and the right-hand side a string literal, introduce
28701 a temporary before expanding assignment into a loop.
28703 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
28704 priority in full, to ensure that any expanded subepxressions of it are
28705 elaborated in the scope of the init_proc.
28707 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
28708 after object declaration, skipping over code that may have been
28709 generated for validity checks.
28711 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
28712 discriminants, ignore the known discriminants of its full view, if
28713 any, to check legality.
28715 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained

29643 checks for bitfield creation are triggered.
29644 (finish_record_type): During last pass over the fields, clear
29645 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

30104 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
30105 N_String_Literal node always references an E_String_Literal_Subtype
30106 entity. This may not be true in the future.
30107 (Possible_Bit_Aligned_Component): Move processing of
30108 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
30110 * exp_ch6.adb (Expand_Thread_Body): Pick up

30115 (Type_May_Have_Bit_Aligned_Components): New function.

30155 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
30156 ineffective elaborate all pragmas on non-visible packages (this
30157 happened when a renamed subprogram was called). Now the elaborate all
30158 always goes on the package containing the renaming rather than the one
30159 containing the renamed subprogram.
30161 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
30162 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

30187 * make.adb (Gnatmake): Special process for files to compile/check when
30188 -B is specified. Fail when there are only foreign mains in attribute

30223 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve

30263 checked when limited aggregates are implemented.

30266 pure, emit warning.

30376 * 5zinit.adb: Clean up.
30378 * 5zintman.adb (Notify_Exception): replaced case statement with a call
30379 to __gnat_map_signal, imported from init.c to support
30380 signal -> exception mappings that depend on the vxWorks version.
30383 Created and exported __gnat_map_signal to support signal -> exception
30384 mapping that is dependent on the VxWorks version.

30415 2003-12-11 Ed Schonberg <schonberg@gnat.com>
30417 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
30418 bounds of a loop, create a separate block in order to generate proper
30419 cleanup actions to prevent memory leaks.
30421 * sem_res.adb (Resolve_Call): After a call to
30422 Establish_Transient_Scope, the call may be rewritten and relocated, in

30441 2003-12-08 Robert Dewar <dewar@gnat.com>
30443 * 7sintman.adb: Minor reformatting
30445 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
30446 standard linker options to get standard libraries linked. We now plan
30447 to provide dummy versions of these libraries to match the appropriate
30448 configurable run-time (e.g. if a library is not needed at all, provide
30449 a dummy empty library).
30451 * targparm.ads: Configurable_Run_Time mode no longer affects linker
30452 options (-L parameters and standard libraries). What we plan to do is
30453 to provide dummy libraries where the libraries are not required.
30455 * gnatbind.adb: Minor comment improvement

30467 of aggregate with default initialized components.
30468 (Has_Default_Init_Comps): Improve implementation to recursively check
30469 all the present expressions.
30471 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
30472 to indicate that the initialization call corresponds to a
30473 default-initialized component of an aggregate.
30474 In case of default initialized aggregate with tasks this parameter is
30475 used to generate a null string (this is just a workaround that must be
30476 improved later). In case of discriminants, this parameter is used to
30477 generate a selected component node that gives access to the discriminant
30480 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
30481 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
30482 allocated aggregates with default-initialized components.
30484 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
30485 the box notation is used in positional aggregates.

30527 Process nodes N_Comment.
30529 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
30530 without comments and there are some comments, set the flag
30531 Unkept_Comments to True.

30573 Correct typo in comment
30574 (Resolve_Aggregate): In case of array aggregates set the estimated
30575 type of the aggregate before calling resolve. This is needed to know
30576 the name of the corresponding IP in case of limited array aggregates.
30577 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
30578 in case of default initialized array components.
30580 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

30600 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
30601 they are automatically generated by Make-lang.in and cause nothing but
30602 maintenance troubles.
30604 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
30606 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

30620 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
30621 to ensure that the kernel fills in the interrupted context structure
30622 before calling a signal handler, which is necessary to be able to
30623 unwind past it. Update the copyright notice.
30625 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
30627 * a-elchha.ads: New file.

30714 2003-12-03 Ed Schonberg <schonberg@gnat.com>
30717 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
30718 is legal in an instance, because legality is cheched in the template.

30739 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
30740 so that the debugger can reliably access the value of the parameter,

34269 2002-01-30 Richard Henderson <rth@redhat.com>
34271 * trans.c (tree_transform) [N_Loop_Statement]: Use
34272 expand_exit_loop_top_cond.

34290 (general) Add @./@: where approriate, and two spaces after the
34291 full stop at the end of a sentence. Use @samp markup when
34292 referring concrete lexical entities (keywords, attribute names
34293 etc.), and @syntax for ARM grammar elements. Use @r for English

34309 function approach did not work well because of a side effect (the
34310 function call could reallocate the table which was being indexed
34311 using its result). Fixes ada/4851.

34372 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no

34678 2001-12-17 Laurent Pautet <pautet@gnat.com>
34681 Fix comment of Shutdown_Socket and Close_Socket. These functions
34682 should not fail silently because if they are called twice, this
34683 probably means that there is a race condition in the user program.
34684 Anyway, this behaviour is consistent with the rest of this unit.
34685 When an error occurs, an exception is raised with the error message
34686 as exception message.

34839 reference nodes, since this field is used in such nodes.

36025 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
36026 instead of simple checksum.
36027 (CRC_Match): new function.
36028 (CRC_Error): new constant.
36030 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
36031 a CRC now and not a simple checksum. A CRC uses lower-case hex
36032 letters, fixes ambiguity in parsing.
36034 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
36035 is what this variable will store.
36037 * bcheck.adb: Change reference to chechsum in comments by CRC.
36038 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
36039 rename All_Checksum_Match to All_CRC_Match. Change due to API
36040 renaming since now GNAT does not use a simple checksum but a
36041 CRC using GNAT.CRC32.
36043 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
36044 now and not anymore a simple checksum.

36081 Update comments for the CRC.
36083 * types.adb (Hex): Use lowercase for the letter part.
36085 * types.ads (Get_Hex_String): Returns the hexadecimal representation
36086 for a word. This is currently used only for CRC. In previous version,
36087 the checksum was using a representation with all letter being
36088 upper-case. With the new implementation (using CRC) we do not remove
36089 the 32th bit of the CRC, so we can have an upper-case starting letter
36090 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
36091 It is ambigous since the CRC was optional and could be followed by
36092 options like EB, EE. So now this routines uses lower-case letter for
36093 the hexadecimal representation. Strange enough only lower case letters
36094 where checked in Scan_ALI (even if this was not a possible case).
36096 * gnatvsn.ads (Library_Version): changed to 3.15a.
36098 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
36101 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
36104 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
36105 Add 2001 to copyright notice
36106 (Accumulate_Checksum): Modify to use System.CRC32.
36108 * ali-util.ads: Redo changes of previous revision to continue to use
36109 the word Checksum. Add 2001 to copyright notice.
36111 * ali.adb: Undo some of previous changes, not needed.
36112 Keep the change for lower case letters in the checksum.
36114 * ali.ads: Undo previous change not needed.
36116 * bcheck.adb: Undo most of previous change, not needed.
36117 But do use Checksums_Match for checksum comparison.
