1236 subprogram body that acts as its own spec may not have a non-private
1237 WITH clause on a private sibling.
1238 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
1239 child unit is a renaming, create an implicit with_clause on that
1240 parent, and not on the unit it renames, to prevent visibility errors

1307 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
1308 type from a limited_with_clause, and the full view is available, use it

1337 Gary Dismukes <dismukes@adacore.com>
1339 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
1340 requeue statement is dispatching. Do not emit an error when the name is
1341 not an entry and the context is a dispatching select. Add code to
1342 perform subtype conformance between the formals of the current entry
1343 and those of the target interface primitive.
1344 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
1345 Timed_Entry_Call): Analyze the triggering statement as the first step of
1346 the processing. If this is a dispatching select, postpone the analysis
1347 of all select statements until the Expander transforms the select. This
1348 approach avoids generating duplicate identifiers after the Expander has
1349 replicated some of the select statements. In case the Expander is
1350 disabled, perform regular analysis.
1351 (Check_Triggering_Statement): New routine.
1352 (Analyze_Requeue): Exclude any interpretations that are not entries when
1353 checking overloaded names in a requeue. Also test type conformance for
1354 matching interpretations rather than requiring subtype conformance at

1359 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
1360 inherited operation is a defaulted tag-indeterminate call, and there is
1361 a statically tagged actual, use the static tag as a controlling actual
1362 for the defaulted actual.
1364 2007-12-13 Geert Bosch <bosch@adacore.com>
1366 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static
1367 context, so do not call Check_Non_Static_Context.

1391 latest Ada 2005 rules about renaming and 'Access of
1392 discriminant-dependent components.

1967 additional management on these nodes in Expand_Interface_Actuals.
1969 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
1970 that handles use of 'Access and 'Unchecked_Access applied to

2016 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
2017 used by VxWorks targets to have access to task-specific data and be
2018 able to extract the stack boundaries for stack checking.

2063 association for an access component, add an association with null as
2064 the expression. Remove testing for array subtypes and the setting in

2066 inclusion of an association for null-initialized arrays. Collapse
2067 condition that tests for array subtypes into just a test of

2254 Add a section on leap seconds control along with two entities used to
2255 enable and disable leap seconds support. The array Leap_Second_Times is
2256 now constant and contains hard time values pre-generated. Remove
2257 all elaboration code used to populate the table of leap seconds.

2318 Eric Botcazou <ebotcazou@adacore.com>
2321 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
2322 indirection added to the HT_Link component of the TSD. This is required
2323 to statically allocate the TSD.
2326 Minor reordering of the declarations in the private part. Required to
2327 add a level of indirection to the contents of the TSD component HT_Link.
2328 This is required to statically allocate the TSD.
2330 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
2331 Is_Statically_Allocated set from constant objects.
2332 Do not make exported constants created by the compiler volatile.
2333 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
2336 * trans.c (Identifier_to_gnu): For constants, unshare initializers
2337 before returning them.
2339 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
2340 public part of the package.
2341 (Make_DT): Move HT_Link component out of the TSD record. For this
2342 purpose Make_DT now declares a separate object that stores the
2343 HT_Link value, and initializes the TSD component with the address
2344 of this new object. The addition of this level of indirection is
2345 required to statically allocate the TSD because the TSD cannot
2346 have variable components.
2347 (Expand_Interface_Conversion): Improve the expanded code.
2348 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
2350 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
2351 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
2352 if we are building static dispatch tables then we must not generate
2353 extra code to register the primitive because the dispatch table will
2354 be built at the end of the library package; otherwise we notify that
2355 we cannot build the static dispatch table.
2357 2007-09-26 Robert Dewar <dewar@adacore.com>
2359 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

2374 for thunks associated with interface types.
2376 * einfo.ads: Improve documentatation of Is_Internal
2377 (Is_Thunk): New attribute applicable to subprograms. True for thunks
2378 associated with interface types.
2379 Extensive comment fixes regarding flags that appear in all entities. The
2380 documentation is now consistent for all such flags (there were a number
2381 of errors in the documentation in this regard).
2383 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
2385 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
2386 of these procedures are passed a function call that already has
2387 build-in-place actuals (testing new flag
2388 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
2389 the case where processing continues.
2390 (Expand_Call): If the call is generated from a thunk body then we
2391 propagate the extra actuals associated with the accessibility
2392 level of the access type actuals.
2394 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
2395 of each extra formal of a protected operation to reference the
2396 corresponding extra formal of the subprogram denoted by the
2397 operation's Protected_Body_Subprogram.
2399 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
2400 N_Function_Call nodes.
2402 2007-09-26 Robert Dewar <dewar@adacore.com>
2404 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
2406 * debug.adb: Add d.s flag.
2408 2007-09-26 Gary Dismukes <dismukes@adacore.com>
2410 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
2411 debug variable so that it won't be initialized when pragma
2412 Initialize_Scalars is in effect.
2414 2007-09-26 Gary Dismukes <dismukes@adacore.com>
2416 * freeze.adb (Freeze_Entity): Remove check for preelaborable
2417 initialization of a full view. This is moved to
2418 Analyze_Package_Specification.
2420 * sem_ch7.adb (Analyze_Package_Specification): Add check for
2421 preelaborable initialization of a full view in entity loop.
2422 (Uninstall_Declarations): If entity is a use-visible compilation unit,
2423 its child units are use-visible only if they are visible child units.
2425 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
2426 whether an expression can be used within a type declaration that
2427 requires preelaborable init.
2428 (Check_Components): Replace inline code that does partial checking for
2429 preelaborable default expressions with call to
2430 Is_Preelaborable_Expression.
2431 (Has_Preelaborable_Initialization): In the case of a generic actual
2432 subtype, (that is, Is_Generic_Actual is True), return the result of
2433 applying Has_Preelaborable_Initialization to the generic actual's base
2436 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
2438 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
2439 call to Jan_1_Day _Of_Week to optimize its performance.
2440 (Is_Leap): Move the routine to the scope of Week_In_Year.
2441 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
2442 weekday on which January 1 falls of Year - 1 and Year + 1. This function
2443 avoids calling Time_Of and Split, thus making it more efficent.
2444 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
2446 * g-calend.ads (Week_In_Year): Change comment to reflect new
2449 2007-09-26 Emmanuel Briot <briot@adacore.com>
2451 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
2452 Command_Line): New types
2453 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
2454 support for defining how switches can be grouped on a command line (as
2455 is the case for -gnatw... for GNAT), and how simple switches can be
2456 used as aliases for more complex switches (-gnatwa is same as
2458 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
2459 (Start, Current_*): New subprograms
2460 Added support for parsing an array of strings in addition to the real
2462 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
2463 be moved from the body to the private part of the spec.
2464 (*): All subprograms now have an extra parameter with default value to
2465 specify which parser should be used. For backward compatibility, it
2466 defaults to parsing the command line of the application. They were also
2467 modified to properly handle cases where each of the argument does not
2468 start at index 1 (which is always true for Ada.Command_Line, but not
2469 when processing any Argument_List).
2470 (Free): New subprogram
2471 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
2472 Argument): New subprograms
2473 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
2474 special characters like ':', '=',... are now handled in a single place,
2475 which makes the code more extensible eventually.
2476 (Getopt, Full_Switch): When the switch was returned as part of the
2477 special character '*', make sure it is prepended by the switch character
2478 ('-' in general), so that the application knows whether "foo" or "-foo"
2479 was specified on the command line.
2481 2007-09-26 Florian Villoing <villoing@adacore.com>
2483 * g-dirope.adb (Remove_Dir): In case we are removing directories
2484 recursively, make sure that if an exception is raised during the
2485 processing, the current working directory is reset to its initial
2486 value before propagating the exception.
2488 2007-09-26 Vincent Celier <celier@adacore.com>
2490 * gnatbind.adb: If there are several ALI files specified and there is
2491 a main program to bind, the first ALI is expected to contain the main
2492 subprogram and the names of the binder generated files will be derived
2493 from the first ALI file name.
2494 (Gnatbind): Fix insertion character in invocation of Error_Msg
2496 2007-09-26 Vincent Celier <celier@adacore.com>
2498 * gnatcmd.adb (Check_Files): Do not include sources that have been
2499 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
2501 2007-09-26 Ed Schonberg <schonberg@adacore.com>
2503 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
2504 information about each of its index types, following the type
2505 reference for its component type.
2507 2007-09-26 Vincent Celier <celier@adacore.com>
2509 * make.adb: (Kill): New procedure (__gnat_kill imported)

2516 sources, so that the correct paths will be found.
2518 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
2520 2007-09-26 Vincent Celier <celier@adacore.com>
2522 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
2524 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
2525 Replace components Compiler_Min_Options and Binder_Min_Options with
2526 Compiler_Required_Switches and Binder_Required_Switches in record
2528 Remove components Default_Language and Config in Project_Tree_Data,
2531 * prj-attr.adb: New attributes Required_Switches (<language>) in
2532 packages Compiler and Binder.
2534 * prj-nmsc.adb: Major rewrite of the processing of configuration
2535 attributes for gprbuild. No impact on GNAT tools.
2537 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer

2543 (Process): Implementation now uses the two new procedures
2545 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
2546 from the project config, not the tree config that no longer exists.

2569 2007-09-26 Ed Schonberg <schonberg@adacore.com>
2571 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
2572 ancestor of the derived type, the operations are inherited from the
2573 primary dispatch table of the parent.
2574 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
2575 when the context is an explicit type conversion.
2577 2007-09-26 Ed Schonberg <schonberg@adacore.com>

2874 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
2875 create an abstract subprogram in the case of 'Input. For 'Output we now
2876 create a real spec/body when the type is abstract, since it can
2877 potentially be called.
2878 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
2879 body for 'Output when the type is abstract (only the creation of the
2880 body for 'Input is excluded when the type is abstract).
2881 (Stream_Operation_OK): Add an additional condition in the return
2882 statement, so that False will be returned for TTS_Stream_Input if the
2883 associated tagged type is an abstract extension. Add comments for
2885 (Expand_N_Object_Declaration): For the case of a shared passive
2886 variable, insert init proc call only after the shared variable
2887 procedures have been processed, because the IP call needs to undergo
2888 shared passive variable reference expansion, which requires these
2889 procedures to be available (and elaborated).

2899 given a box association, the type of the component is discriminated,
2900 and the value of the discriminant is the discriminant of the enclosing
2901 type, retrieve its value from the aggregate itself, where it must have
2904 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
2905 to remove other spurious ambiguities on arithmetic operations involving
2906 literals and addresses, on systems where Address is a visible integer
2907 type, when the operator is called in functional notation.
2908 (Try_Primitive_Operation): Within an instance, a call in prefixed form
2909 is legal when the types match, even if the operation is currently
2912 2007-09-10 Ed Schonberg <schonberg@adacore.com>
2914 * sem_ch12.adb (Build_Local_Package): A formal package with no
2915 associations is legal if all formals have defaults. It is not

2946 2007-09-08 Eric Botcazou <ebotcazou@adacore.com>
2948 * decl.c (gnat_to_gnu_entity) <Object>: Simplify the condition under
2949 which a constant renaming is treated as a normal object declaration.
2950 * trans.c (lvalue_required_p) <N_Slice>: New case, extracted from
2951 the N_Indexed_Component case.
2952 <N_Indexed_Component>: Fall through to above case.

3034 (Write_Entity_Flags): Write the status of flag Is_Raised.
3035 (Is_Descendent_Of_Address): New entity flag, to simplify handling of

3057 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
3058 library-level package renaming, pass the declaration associated with
3059 the renaming's special debug variable to Qualify_Entity_Names to ensure
3060 that its encoded name is properly qualified.
3062 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
3063 occurring in the list of entities to qualify, and do not attempt to
3064 traverse an entity list in that case. Variables associated with
3065 ` library-level package renamings can now occur in the table.

3084 to include loop parameters.
3085 (Valid_Conversion): Avoid generation of spurious error message.

3089 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
3090 concatenations of string literals into a single literal, in order to
3091 avoid very deep recursion in the front end, which was causing stack
3094 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
3095 string, and the right operand is a string literal (the case of "" &
3096 "..."), optimize by avoiding copying the right operand -- just use the
3097 value of the right operand directly.
3099 * stringt.adb (Store_String_Chars): Optimize by growing the
3100 String_Chars table all at once, rather than appending characters one by
3102 (Write_String_Table_Entry): If the string to be printed is very long,
3103 just print the first few characters, followed by the length. Otherwise,
3104 doing "pn(n)" in the debugger can take an extremely long time.
3106 * sem_prag.adb (Process_Interface_Name): Replace loop doing
3107 Store_String_Char with Store_String_Chars.

3124 2007-08-31 Ed Schonberg <schonberg@adacore.com>
3126 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
3127 flag, for effiency. It is called when analyzing arithmetic operators
3128 and also for actuals in calls that are universal_integers. The flag is
3129 set for the predefined type address, and for any type or subtype
3132 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
3133 Universal_Integer, when the formal is a descendent of address and the
3134 call appears in user code.

3214 (Debug_Renaming_Declaration): Replace creation of an enumeration type
3215 and literal with creation of a variable of type
3216 Standard_Debug_Renaming_Type whose name encodes both the renamed object

3226 Ed Schonberg <schonberg@adacore.com>
3227 Javier Miranda <miranda@adacore.com>
3229 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
3230 ancestor part given by an aggregate to test for an unchecked conversion,
3231 since this can occur in some cases when the ancestor part is a function
3232 call, and we don't want to fall into the recursive call to this
3233 procedure in that case.
3235 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
3236 stream attributes on limited types to account for user-specified
3237 attributes as well as whether Input (resp. Output) becomes available
3238 due to Read (resp. Write) being available for the type. Change Boolean
3239 variable to the more accurate name
3240 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
3241 double-"not" predicate at beginning of return statement to more
3242 understandable form.
3244 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
3245 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
3246 in a block statement and use that as the first statement of the
3247 expanded return rather than incorrectly using the handled sequence as
3248 the first statement.
3250 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
3251 operation, generate an explicit freeze node for it rather than
3252 generating extra formals, to ensure that gigi has the proper order of
3253 elaboration for anonymous subtypes in the signature of the subprograms.
3254 (Build_In_Place_Formal): Move assertion to beginning of loop.
3255 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
3256 applied to a function call (occurs for some cases of 'Input).

3258 applied to a function call (occurs for some cases of 'Input).
3260 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
3261 2005, generate an extended return statement enclosing the result object
3264 * freeze.adb (Freeze_Record_Type): Extend the current management of
3265 components that are access type with an allocator as default value: add
3266 missing support to the use of qualified expressions of the
3267 allocator (which also cause freezing of the designated type!)
3268 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
3269 dispatching operation, since extra formals may be needed by calls to
3270 build-in-place functions (such as stream 'Input).
3272 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
3273 formals for 'Constrained and accessibility level in the case of a
3274 predefined dispatching operation.
3276 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
3277 point, no need to find the parent node.
3279 2007-08-16 Javier Miranda <miranda@adacore.com>
3281 * exp_attr.adb (Attribute_Priority): Add missing support for entries
3284 2007-08-16 Javier Miranda <miranda@adacore.com>
3286 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
3287 is not really required and can introduce regression with the debugger.
3288 The original problem is fixed with the patch written for checks.adb.
3290 2007-08-16 Thomas Quinot <quinot@adacore.com>
3292 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

3300 Including_Non_Switch set to False.
3302 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
3303 parameter Including_Non_Switch, defaulted to True. When
3304 Including_Non_Switch is False, options that are not switches and
3305 appear as relative path are not converted to absolute paths.

3320 from the immediate ancestor of Main_Unit_Entity.
3321 (Install_Limited_Withed_Unit): Do not install the limited view of
3322 package P if P is reachable through an ancestor chain from package C
3323 and C also has a with clause for P in its body.
3324 (Has_Limited_With_Clause): New routine.
3325 (Has_With_Clause): New routine.
3327 2007-08-16 Ed Schonberg <schonberg@adacore.com>
3329 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
3330 generic for an enclosing instance is a global reference, even though
3331 its scope is the enclosing instance.
3333 2007-08-16 Gary Dismukes <dismukes@adacore.com>
3334 Javier Miranda <miranda@adacore.com>
3336 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to

3354 Bob Duff <duff@adacore.com>
3355 Nicolas Setton <setton@adacore.com>
3357 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
3358 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
3359 the statement which is being resolved comes from a predefined library
3360 unit, all non-predefined library interpretations are skipped.
3361 (Resolve_Op_Concat): If string concatenation was folded in the parser,
3362 but the "&" is user defined, give an error, because the folding would
3365 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
3366 the parser has folded a long sequence of concatenations of string
3369 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
3370 and "JMP_BUF" variables as artificial.
3371 (N_String_Literal): Do not use alloca for very long string literals. Use
3372 xmalloc/free instead. Otherwise the stack might overflow.

3425 needed for access to concurrent record types generated by the expander.
3426 (Generate_Range_Check): When generating a temporary to capture the
3427 value of a conversion that requires a range check, set the type of the
3428 temporary before rewriting the node, so that the type is always
3429 properly placed for back-end use.
3430 (Apply_Float_Conversion_Check): Handle case where the conversion is
3432 (Get_Discriminal): Code reformatting. Climb the scope stack looking

3448 (Expand_N_Type_Conversion): Test for the case of renamings of access
3449 parameters when deciding whether to apply a run-time accessibility
3451 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
3452 aggregate code before allocator, and ahead of declaration for
3453 temporary, to prevent access before elaboration when the allocator is
3454 an actual for an access parameter.
3455 (Expand_N_Type_Conversion): On an access type conversion involving an
3456 access parameter, do not apply an accessibility check when the
3457 operand's original node was an attribute other than 'Access. We now
3458 create access conversions for the expansion of 'Unchecked_Access and
3459 'Unrestricted_Access in certain cases and clearly accessibility should
3460 not be checked for those.
3462 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
3463 includes a type conversion of a packed component that has been expanded,
3464 recover the original expression for the object, and use this expression
3465 in the post-call assignment statement, so that the assignment is made
3466 to the object and not to a back-end temporary.
3467 (Freeze_Subprogram): In case of primitives of tagged types not defined
3468 at the library level force generation of code to register the primitive
3469 in the dispatch table. In addition some code reorganization has been
3470 done to leave the implementation clear.

3472 preserve the type of the inherited function after the intrinsic
3473 operation has been expanded.
3475 * exp_ch2.ads, exp_ch2.adb
3476 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
3477 of an entry formal appearing in an assignment statement does not assign
3479 (Expand_Current_Value): Instead of calling a routine to determine
3480 whether the prefix of an attribute reference should be optimized or
3481 not, prevent the optimization of such prefixes all together.
3483 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
3484 component whose prefix is known to be of an access type is an implicit
3485 dereference and does not assign to the prefix.

3494 (Array_Aggr_Subtype): Associate each itype created for an index type to
3495 the corresponding range construct, and not to the aggregate itself. to
3496 maintain a one-to-one correspondence between itype and its associated
3497 node, to prevent errors when complex expression is copied.
3498 Fix mishandling of multiple levels of parens
3500 * sem_aggr.adb: Create a limited view of an incomplete type, to make
3501 treatment of limited views uniform for all visible declarations in a
3502 limited_withed package.
3503 (New_Copy_Tree): If hash table is being used and itype is visited,
3504 make an entry into table to link associated node and new itype.
3505 (Resolve_Record_Aggregate): Do not add an others box association for a
3506 discriminated record component that has only discriminants, when there
3507 is a box association for the component itself.
3509 * par-ch4.adb: Fix mishandling of multiple levels of parens
3511 2007-08-14 Robert Dewar <dewar@adacore.com>

3545 Gary Dismukes <dismukes@adacore.com>
3547 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
3548 to make treatment of limited views uniform for all visible declarations

3556 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
3557 generation of a freezing node to ensure proper management of null
3558 excluding access types in the backend.
3559 (Create_Extra_Formals): Test base type of the formal when checking for
3560 the need to add an extra accessibility-level formal. Pass the entity E
3561 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
3562 originally being done in a couple of cases), to ensure that the
3563 Extra_Formals list gets set on the entity E when the first entity is
3565 (Conforming_Types): Add missing calls to Base_Type to the code that
3566 handles anonymous access types. This is required to handle the
3567 general case because Process_Formals builds internal subtype entities
3568 to handle null-excluding access types.
3569 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
3570 functions that need it, even when not marked Requires_Overriding.
3571 Improve warnings for in out parameters
3572 (Analyze_Function_Return): Warn for disallowed null return
3573 Warn on return from procedure with unset out parameter
3574 Ensure consistent use of # in error messages
3575 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
3576 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
3577 the implicit conversion of the expression done for anonymous access
3578 types. This is required to generate the code of the null excluding
3579 check (if required).
3581 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
3582 A formal parameter is never publicly referenceable outside of its body.
3583 (Check_References): For an unreferenced formal parameter in an accept
3584 statement, use the same warning circuitry as for subprogram formal
3586 (Warn_On_Unreferenced_Entity): New subprogram, taken from
3587 Output_Unreferenced_Messages, containing the part of that routine that
3588 is now reused for entry formals as described above.
3589 (Goto_Spec_Entity): New function
3590 (Check_References): Do not give IN OUT warning for dispatching operation
3591 Improve warnings for in out parameters
3592 (Test_Ref): Check that the entity is not undefinite before calling
3593 Scope_Within, in order to avoid infinite loops.
3594 Warn on return from procedure with unset out parameter
3595 Improved warnings for unused variables

3599 Gary Dismukes <dismukes@adacore.com>
3601 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
3602 (Expand_N_Attribute_Reference): Further unify the handling of the
3603 three forms of access attributes, using common code now for all three
3604 cases. Add a test for the case of applying an access attribute to
3605 an explicit dereference when the context is an access-to-interface
3606 type. In that case we need to apply the conversion to the prefix
3607 of the explicit dereference rather than the prefix of the attribute.
3608 (Attribute_Version, UET_Address): Set entity as internal to ensure
3609 proper dg output of implicit importation.
3610 (Expand_Access_To_Type): Removed.
3611 (Expand_N_Attribute_Reference): Merge the code from the three cases
3612 of access attributes, since the processing is largely identical for
3613 these cases. The substantive fix here is to process the case of a
3614 type name prefix (current instance case) before handling the case
3615 of interface prefixes.

3619 Javier Miranda <miranda@adacore.com>
3620 Robert Dewar <dewar@adacore.com>
3622 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
3623 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
3624 type that is an anonymous access to controlled object, establish
3625 an associated finalization chain to avoid corrupting the global
3626 finalization list when a dynamically allocated object designated
3627 by such a component is deallocated.
3628 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
3629 functions that need it, even when not marked Requires_Overriding.
3630 (Initialize_Tag): Replace call to has_discriminants by call to
3631 Is_Variable_Size_Record in the circuitry that handles the
3632 initialization of secondary tags.

3634 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
3635 Suppress_Initialization pragma for a derived type.
3636 (Is_Variable_Size_Record): New subprogram.
3637 (Build_Offset_To_Top_Functions): New implementation that simplifies the
3638 initial version of this routine and also fixes problems causing
3639 incomplete initialization of the table of interfaces.
3640 (Build_Init_Procedure): Improve the generation of code to initialize the
3641 the tag components of secondary dispatch tables.
3642 (Init_Secondary_Tags): New implementation that simplifies the previous
3643 version of this routine.

3645 object declaration, for diagnostic purposes.
3646 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
3647 diagnose attemps to freeze a subprogram when some untagged type of its
3648 profile is a private type whose full view has not been analyzed yet.
3649 (Freeze_Array_Type): Generate init proc for packed array if either
3650 Initialize or Normalize_Scalars is set.
3651 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
3652 constructing the new profile, copy the null_exclusion indicator for each
3653 parameter, to ensure full conformance of the new body with the spec.
3655 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
3656 Create wrappers for constructor functions that need it, even when not
3657 marked Requires_Overriding.
3658 (Covers): Handle properly designated types of anonymous access types,
3659 whose non-limited views are themselves incomplete types.
3660 (Add_Entry): Use an entity to store the abstract operation which hides
3662 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
3663 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
3664 initialization aggregate.
3665 (Function_Interp_May_Be_Hidden): Rename to

3668 they are labeled as potentially hidden by an abstract operator.
3669 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
3670 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
3671 (Write_Overloads): Output the abstract operator if present.
3672 (Add_Entry): Before inserting a new entry into the interpretation table
3673 for a node, determine whether the entry will be disabled by an abstract
3675 (Binary_Op_Interp_May_Be_Hidden): New routine.
3676 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
3678 (Function_Interp_May_Be_Hidden): New routine.
3679 (Has_Compatible_Type): Do not consider interpretations hidden by
3680 abstract operators when trying to determine whether two types are
3682 (Has_Hidden_Interp): New routine.
3683 (Set_May_Be_Hidden_Interp): New routine.
3684 (Write_Overloads): Write the status of flag May_Be_Hidden.

3687 Javier Miranda <miranda@adacore.com>
3689 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
3690 types declared in the declarative part of a nested package body or in
3691 the proper body of a stub.

3697 output of implicit importation and exportation.
3698 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
3699 first formal of the thunk is always associated with the controlling
3700 type. In addition perform the following code cleanup: remove formal
3701 Thunk_Alias which is no longer required, cleanup evaluation of the
3702 the controlling type, and update the documentation.
3703 Replace occurrence of Default_Prim_Op_Count by
3704 Max_Predef_Prims. Addition of compile-time check to verify
3705 that the value of Max_Predef_Prims is correct.
3706 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
3707 (Make_DT): Add parameter to indicate when type has been frozen by an
3708 object declaration, for diagnostic purposes.

3710 construction of statically allocated dispatch tables.
3711 (Make_DT): In case of library-level tagged types export the declaration
3712 of the primary tag. Remove generation of tags (now done by Make_Tags).
3713 Additional modifications to handle non-static generation of dispatch
3714 tables. Take care of building tables for asynchronous interface types
3715 (Make_Tags): New subprogram that generates the entities associated with
3716 the primary and secondary tags of Typ and fills the contents of Access_
3717 Disp_Table. In case of library-level tagged types imports the forward
3718 declaration of the primary tag that will be declared later by Make_DT.
3719 (Expand_Interface_Conversion): In case of access types to interfaces
3720 replace an itype declaration by an explicit type declaration to avoid
3721 problems associated with the scope of such itype in transient blocks.
3723 2007-08-14 Robert Dewar <dewar@adacore.com>
3724 Ed Schonberg <schonberg@adacore.com>
3725 Javier Miranda <miranda@adacore.com>
3727 * exp_util.ads, exp_util.adb:
3728 This patch replaces a number of occurrences of explicit tests for N_Null
3729 with calls to Known_Null. This improves tracking of null values, since
3730 Known_Null also catches null constants, and variables currently known to
3731 be null, so we get better tracking.
3732 (Ensure_Defined): create an itype reference only in the scope of the
3734 (Side_Effect_Free): A selected component of an access type that
3735 denotes a component with a rep clause must be treated as not
3736 side-effect free, because if it is part of a linked structure its
3737 value may be affected by a renaming.
3738 (Expand_Subtype_From_Expr): For limited objects initialized with build
3739 in place function calls, do nothing; otherwise we prematurely introduce
3740 an N_Reference node in the expression initializing the object, which
3741 breaks the circuitry that detects and adds the additional arguments to
3742 the called function. Bug found working in the new patch for statically
3743 allocated dispatch tables.
3744 (Is_Library_Level_Tagged_Type): New subprogram.
3745 (Remove_Side_Effects): If the expression of an elementary type is an
3746 operator treat as a function call.
3747 (Make_Literal_Range): If the index type of the array is not integer, use
3748 attributes properly to compute the constraint on the resulting aggregate
3751 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
3752 class-wide type whose base type is an incomplete private type, leave
3753 class-wide type unfrozen so that freeze nodes can be generated
3754 properly at a later point.
3755 (Freeze_Entity, array case): Handle case of pragma Pack and component
3756 size attributre clause for same array.

3816 source dirs are not known.
3817 (Check_Ada_Name): Allow all identifiers that are not reserved words
3819 Major update of the Project Manager and of the project aware tools,
3820 including gprmake, so that the same sources in the GNAT repository
3821 can be used by gprbuild.

4384 (Set_Item): When the new item is an element of the currently allocated
4385 table passed by reference, save a copy on the stack if we're going

4400 Thomas Quinot <quinot@adacore.com>
4402 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
4403 derived type with interface progenitors use the analyzed formal as the
4404 parent of the actual, to create renamings for all the inherited
4405 operations in Derive_Subprograms.
4406 (Collect_Previous_Instances): new procedure within of
4407 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
4408 unit being loaded, to ensure that the generation of global symbols is
4409 consistent in different compilation modes.
4410 (Is_Tagged_Ancestor): New function testing the ancestor relation that
4411 takes progenitor types into account.
4412 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
4413 traversing over the primitives of the formal and actual types to locate
4414 any abstract subprograms of the actual type that correspond to a
4415 nonabstract subprogram of the formal type's ancestor type(s), and issue
4416 an error if such is found.
4417 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
4418 Instantiate_Package_Body, Instantiate_Subprogram_Body):
4419 Remove bogus guard around calls to Inherit_Context.

4424 a predefined or internal unit.
4426 2007-08-14 Ed Schonberg <schonberg@adacore.com>
4428 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
4429 parameter to determine whether operation applies to the prefix.
4430 (Complete_Object_Operation): If actual has an access type and
4431 controlling formal is not an in_parameter, reject the actual if it is
4432 an access_to_constant type.
4433 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
4434 type, the candidate operations are found in the scope of declaration of
4435 the type, because the type has no primitive subprograms.
4436 (Analyze_Selected_Component): If prefix is class-wide, and root type is
4437 a private extension, only examine visible components before trying to
4438 analyze as a prefixed call.
4439 Change Entity_List to Type_To_Use, for better readability.
4440 (Has_Fixed_Op): Use base type when checking whether the type of an
4441 operator has a user-defined multiplication/division
4442 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
4443 user-defined operators are available for fixed-point types.

4448 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
4449 formal At_Any_Place indicating, when True, that we want to test for
4450 availability of the stream attribute at any place (as opposed to the
4451 current visibility context only).
4452 (Missing_Read_Write_Attributes): A stream attribute is missing for the
4453 purpose of enforcing E.2.2(8) only if it is not available at any place.
4454 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
4455 when checking the legality of an extension aggregate in a preelaborable
4456 package. Treat the literal null as a valid default expression in a
4457 component declaration for a type with preelaborable initialization.
4458 A limited interface is a legal progenitor for the designated type of a
4459 remote access to class-wide type.

4472 (Find_Selected_Component, Has_Components): Handle properly non-limited
4473 views that are themselves incomplete types.
4474 Handle interfaces visible through limited-with clauses.
4475 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
4476 subprogram generic actual for which we have generated a renaming.
4477 Warn when the renaming introduces a homonym of

5671 Arnaud Charlet <charlet@adacore.com>
5673 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
5674 applicable to types that have the With_Type flag set. Returns the
5675 non-limited view of the type, if available, otherwise the type itself.
5676 For class-wide types, there is no direct link in the tree, so we have
5677 to retrieve the class-wide type of the non-limited view of the Etype.
5678 New attributes Static_Initialization and Static_Elaboration_Desired.
5679 Remove the pragma Thread_Body, and the associated flag

5690 components of records. Set to point to the entity of the corresponding
5692 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
5693 (Original_Access_Type): Remove, not needed.
5694 (Root_Type): Handle properly subtypes of class-wide-types.
5697 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
5698 class-wide types visible through limited-with clauses.
5699 (Try_Primitive_Operation): When examining all primitive operations of a
5700 tagged type, do not consider subprograms labeled as hidden unless they
5701 belong to a private generic type with a tagged parent.
5702 (Try_Object_Operation): Extensive rewriting, to handle properly various
5703 overloading cases, when several ancestors may have class-wide operations
5704 that are possible candidates, and when the overloaded functions return
5705 array types and have defaulted parameters so that the call may be
5706 interpreted as an indexing.
5707 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
5708 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
5709 successive actuals before analyzing the call itself.
5710 (Try_Primitive_Operation): A primitive operation is compatible with the
5711 prefix if the prefix has a synchronized type and the type of the formal
5712 is its corresponding record, as can be the case when the primitive
5713 operation is declared outside of the body of the type.
5714 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
5715 perform homonym traversal, looking for class-wide operation matches
5716 (formerly done in statements of Try_Class_Wide_Operation). Matches on
5717 access parameters are now restricted to anonymous access types.
5718 (Mark_Allocator): An allocator with a discriminant association parent is
5720 (Try_One_Prefix_Interpretation): If the type of the object is
5721 incomplete, as can be happen when it is a limited view obtained through
5722 a limited_with_clause, the selected component is not part of a prefixed
5724 (Complete_Object_Operation): Diagnose properly an object that is not
5725 aliased when the corresponding controlling formal is an access
5727 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
5728 ambiguous calls in prefixed notation, where two primitives differ only
5729 in that the controlling argument of one is an access parameter.
5731 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
5732 whether a function that returns an unconstrained type can be inlined.
5733 (Process_Formals): Diagnose properly the illegal use of an incomplete
5734 type in the profile of an access_to_subprogram declaration.
5735 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
5736 operations are attached to the corresponding record.
5737 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
5738 When processing a primitive of a concurrent type which implements an
5739 interface change the type of all controlling formals to that of the
5740 corresponding record type.
5741 (Check_Synchronized_Overriding): Relax the conditional logic when trying
5742 to determine the tagged type to which a primitive belongs.
5743 (Check_Conventions): Capture condition to ignore a primitive operation
5744 (which is shared between the loop in Check_Conventions and the one in
5745 Check_Convention) in a new local function Skip_Check.
5746 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
5747 confusion with Check_Conventions' own Prim_Op local variable.
5748 (Create_Extra_Formals): Test for a tagged result type rather than a
5749 controlling result when determining whether to add a BIP_Alloc_Form
5750 formal and a BIP_Final_List formal to the function.
5751 (Check_Conformance); For parameters that are anonymous access types,
5752 subtype conformance requires that the not null and the constant
5753 indicators must match
5754 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
5755 to retrieve the appropriate type when processing a concurrent type
5756 declared within a generic. Minor comment reformatting. Change invocation
5757 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
5759 (Analyze_Subprogram_Body): If the return type of a function is an
5760 anonymous access to the limited view of a class-wide type, and the
5761 non-limited view of the type is available, update the type of the
5762 function so that code can be generated.
5763 (Process_Formals): In case of access-subtype itype whose designated
5764 type is also an itype (situation that happens now with access to
5765 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
5766 attribute to avoid backend problems.
5767 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
5768 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
5769 anonymous types' designated types are same before testing
5770 Subtypes_Statically_Match.
5771 (Create_Extra_Formals): Test for a named access parameter that is a
5772 controlling formal as an additional condition for adding an
5773 accessibility level formal. This can occur in the subp type created for
5774 dispatching calls in Expand_Dispatching_Call, and allows calling
5775 Create_Extra_Formals from that procedure rather than special-casing the
5776 extra formals there.
5777 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
5778 when the function has a controlling result.
5779 (Check_Returns): Add much more knowledge of the optimization of local
5780 raise statements to gotos, to retain proper warnings in this case.
5781 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
5782 nodes when looking for last statement.
5784 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
5785 class-wide types visible through limited with clauses.
5786 (Add_One_Interp): If the operands are anonymous access types, the
5787 predefined operator on universal_access is immediately visibles
5788 (Find_Unique_Type): Handle anonymous access to subprogram types just as
5789 other anonymous access types.
5790 (Disambiguate): Take into account CIL convention.
5791 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
5793 2007-06-06 Robert Dewar <dewar@adacore.com>

5811 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
5812 in extension aggregates.
5813 (Flatten): Other conditions being met, an aggregate is static if the
5814 low bound given by component associations is different from the low
5815 bound of the base index type.
5816 (Packed_Array_Aggregate_Handled): If the component type is itself a
5817 packed array or record, the front-end must expand into assignments.
5818 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
5819 Init_Pr, instead of Ancestor_Is_Expression.
5820 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
5821 coextension chain root, either generate a list controller or use the
5822 already existing one.
5823 (Static_Array_Aggregate): New procedure to construct a positional
5824 aggregate that can be handled by the backend, when all bounds and
5825 components are compile-time known constants.
5826 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
5827 types covering interface types into assignments.
5828 (Replace_Type): move to Build_Record_Aggr_Code.
5829 (Expand_Record_Aggr_Code): if the target of the aggregate is an
5830 interface type, convert to the definite type of the aggregate itself,
5831 so that needed components are visible.
5832 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
5833 components and the context is an extended return statement do not
5834 create a transient block for it, to prevent premature finalization
5835 before the return is executed.
5836 (Gen_Assign): Do not generate a call to deep adjust routine if the
5837 component type is itself an array of controlled (sub)-components
5838 initialized with an inner aggregate.
5839 (Component_Check): New name for Static_Check. This name is now more
5840 appropriate, and documentation is added which was missing.
5841 (Component_Check): Add test for bit aligned component value
5842 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
5843 Tagged_Comps, name is more appropriate given added function below.
5844 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

5848 Robert Dewar <dewar@adacore.com>
5850 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
5851 Terminated: Add unchecked type conversion from System.Address to
5852 System.Tasking.Task_Id when calling the predefined primitive
5854 Disable new Ada 05 accessibility check for JVM.NET targets, which
5855 cannot be implemented in a practical way.
5856 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
5857 the sources always references the tag of the actual object. Therefore,
5858 if 'Tag is applied in the sources to class-wide interface objects we
5859 generate code that displaces "this" to reference the base of the object.
5860 (Expand_N_Attribute_Reference, case Size): Return specified size if
5862 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
5863 has code that displaces the pointer of the object to manage interface
5864 types. However this code must not be executed when the prefix is a
5865 subprogram. This bug caused the wrong expansion of the internally
5866 generated assignment that fills the dispatch table when the primitive
5867 is a function returning a class-wide interface type.
5868 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
5869 Set_Attribute_Name for Name_Unaligned_Valid.

5872 Gary Dismukes <dismukes@adacore.com>
5874 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
5875 If the initialization is the equivalent aggregate of the initialization
5876 procedure of the type, do not remove it.
5877 (Expand_N_Attribute_Definition_Clause): Exclude access variables
5878 initialized to null from having their expression reset to empty and
5879 note this exception in the comment.

5884 Gary Dismukes <dismukes@adacore.com>
5886 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
5887 Add "with" and "use" clauses for Sem_Attr.
5888 (Expand_Current_Value): Do not replace occurences of attribute
5889 references where the prefix must be a simple name.
5891 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
5892 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
5893 Attribute_Requires_Simple_Name_Prefix.
5894 (Name_Modifies_Prefix): Body of new function.
5895 (Requires_Simple_Name_Prefix): Body of new function.
5896 (Resolve_Attribute, case Access): Improve error message for case of
5897 mismatched conventions.
5898 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
5900 (Analyze_Attribute, case 'Access): If the type of the prefix is a
5901 constrained subtype for a nominal unconstrained type, use its base type
5902 to check for conformance with the context.
5903 (Resolve_Attribute): Remove test of the access type being associated
5904 with a return statement from condition for performing accessibility
5905 checks on access attributes, since this case is now captured by
5906 Is_Local_Anonymous_Access.
5907 (Analyze_Access_Attribute): Set Address_Taken on entity
5908 (Analyze_Attribute, case Address): Set Address_Taken on entity
5909 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
5910 validating an access attribute whose prefix is a current instance.
5911 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
5912 applied to dispatching operations, if freezing is required then we set
5913 the attribute Has_Delayed_Freeze in the prefix's entity.
5914 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
5915 current scope if access of local subprogram taken
5916 (Analyze_Access_Attribute): Check legality of self-reference even if the
5917 expression comes from source, as when a single component association in
5918 an aggregate has a box association.
5919 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
5920 the prefix if it is a protected operation and the attribute is
5921 Unrestricted_Access.
5922 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
5923 reference to the base type of the context, to force a constraint check
5924 when the context is an access subtype with an explicit constraint.
5925 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
5926 node is rewritten as an interface conversion. leave unanalyzed after
5927 resolution, to ensure that type checking against the context will take

5931 Javier Miranda <miranda@adacore.com>
5932 Robert Dewar <dewar@adacore.com>
5934 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
5935 wrapper when the full view of the controlling type of an inherited
5936 function that dispatches on result implements interfaces.
5937 (Expand_N_Object_Declaration): In cases where the type of the
5938 declaration is anonymous access, create finalization list for it.
5939 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
5940 if the object has no explicit initialization, to match description of
5941 functionality of pragam Persistent_BSS.
5942 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
5943 new function to build static aggregates, to replace initialization call
5944 when static initialization is desired.
5945 (Freeze_Type): Generate a list controller for an access type whenever
5946 its designated type has controlled anonymous access discriminants.
5947 (Build_Equivalent_Aggregate): New procedure to compute a static
5948 aggregate to be used as default initialization for composite types,
5949 instead of a generating a call to the initialization procedure for the
5951 (Build_Initialization_Call): When available, replace a call to the
5952 initialization procedure with a copy of the equivalent static aggregate
5954 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
5955 declarations for objects of a class-wide interface type, rather than
5956 just identifiers, to prevent visibility problems.
5957 (Expand_N_Object_Declaration): When expanding the declaration for an
5958 object of a class-wide interface type, preserve the homonym chain of
5959 the original entity before exchanging it with that of the generated
5960 renaming declaration.
5961 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
5962 active, because there is no way to handle the exception.
5963 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
5964 to do a minimum decoration of the Access_Disp_Table list.
5965 (Expand_Record_Controller): Avoid the addition of the controller between
5966 the component containing the tag of a secondary dispatch table and its
5967 adjacent component that stores the offset to the base of the object.
5968 This latter component is only generated when the parent type has
5969 discriminants ---documented in Add_Interface_Tag_Components).
5970 (Apply_Array_Size_Check): Removed, no longer needed.
5971 (Expand_N_Full_Type_Declaration): If the type has anonymous access
5972 components, create a Master_Entity for it only if it contains tasks.
5973 (Build_Init_Procedure): Suppress the tag assignment compiling under
5975 (Freeze_Record_Type): Remove code associated with creation of dispatch
5977 (Init_Secondary_Tags): Update type of actuals when generating calls to
5978 Ada.Tags.Set_Offset_To_Top
5979 (Stream_Operation_OK): Disable use of streams compiling under no
5981 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
5982 if Has_Init_Expression set.
5983 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
5984 Register_Primitive, which provides the same functionality.
5985 (Requires_Init_Proc): Return false in case of interface types.
5986 (Add_Secondary_Tables): Use the new attribute Related_Interface to
5988 (Predefined_Primitive_Freeze): Do not assume that an internal entity
5989 is always associated with a predefined primitive because the internal
5990 entities associated with interface types are not predefined primitives.
5991 Therefore, the call to Is_Internal is replaced by a call to the
5992 function Is_Predefined_Dispatching_Operation.
5993 (Make_Eq_If): When generating the list of comparisons for the
5994 components of a given variant, omit the controller component that is
5995 present if the variant has controlled components.

5998 Hristian Kirtchev <kirtchev@adacore.com>
5999 Bob Duff <duff@adacore.com>
6001 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
6002 handle the creation of finalization lists and calls for nested
6003 coextensions when the root of the chains is part of a return statement.
6004 (Inside_A_Return_Statement): New function inside Complete_Coextension_
6006 (Expand_Record_Equality): Skip components that are interface types.
6007 (Displace_Allocator_Pointer): Add missing support for interface subtypes
6008 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
6009 with Rewrite_Coextension. Change the condition for detecting coextension
6011 (Is_Local_Access_Discriminant): Removed.
6012 (Rewrite_Coextension): New routine which rewrites a static coextension
6013 as a temporary and uses its unrestricted access in the construction of
6015 (Complete_Coextension_Finalization): New routine. Generate finalization
6016 attachment calls to all delayed coextensions.
6017 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
6018 the allocator is not a coextension itself and has delayed coextensions.
6019 If the current allocator is controlled, but also a coextension, delay
6020 the generation of the finalization attachment call.
6021 Rename local variable "Node" to "Nod" in order to avoid confusion with
6023 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
6024 limited types that are not inherently limited. Such an allocator is
6025 illegal, but is generated by the expander for a return statement, to
6026 copy the result onto the secondary stack. This is the only case where a
6027 limited object can be copied. Generate code to displace the pointer
6028 to the object if the qualified expression is a class-wide interface
6029 object. Such displacement was missing and hence the copy of the object
6031 (Apply_Accessibility_Check): Handle allocated objects initialized in
6033 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
6034 and Expand_Allocator_Expression. Allocating class-wide interface objects
6035 this routine displaces the pointer to the allocated object to reference
6036 the component referencing the corresponding secondary dispatch table.
6037 Expand_Allocator_Expression): Add missing support to allocate class-wide
6038 interface objects initialized with a qualified expression.
6039 (Get_Allocator_Final_List): Test for an anonymous access type that is a
6040 function result type, and use the finalization list associated with the
6041 function scope in that case (such an anonymous type should not be
6042 treated like an access parameter's type).

6045 Gary Dismukes <dismukes@adacore.com>
6046 Javier Miranda <miranda@adacore.com>
6048 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
6049 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
6050 required exception handler.
6051 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
6052 properly the case of a function whose return type is a limited
6053 class-wide interface type. Modify the code of the accessibility
6054 check to handle class-wide interface objects. In this case we need to
6055 displace "this" to reference the primary dispatch table to get access
6056 to the TSD of the object (to evaluate its accessibility level).
6057 (Expand_N_Extended_Return_Statement): Test for a tagged result type
6058 rather than a controlling result as one of the conditions for
6059 generating tests of the implicit BIP_Alloc_Form formal. The
6060 initialization assignment is also handled according to whether the
6061 result is tagged instead of controlling.
6062 In the case where the init assignment is inserted in the "then" part of
6063 the allocation conditional, rewrite the target to be a dereference of
6064 the implicit BIP_Object_Access formal.
6065 If the returned value is unconstrained and created on the secondary
6066 stack, mark the enclosing block and function so that the secondary
6067 stack is not reclaimed on return.
6068 Treat returns from functions with controlling results similarly to
6069 returns from functions with unconstrained result subtypes.
6070 If the object returned is unconstrained, and an allocator must be
6071 created for it, analyze the allocator once the block for the extended
6072 return is installed, to ensure that finalizable components
6073 of the expression use the proper finalization list. Guard the call to
6074 Move_Final_List with a check that there is something to finalize.
6075 (Make_Tag_Ctrl_Assignment): Use "old" handling
6076 of controlled type assignment for virtual machines, since new code uses
6077 unsupported features (such as direct access to bytes in memory).
6079 2007-06-06 Gary Dismukes <dismukes@adacore.com>
6080 Ed Schonberg <schonberg@adacore.com>
6082 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
6083 accessibility actual, check for the case of an aliased object that has
6084 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
6085 we fall into processing for the attribute rather than the name of the
6087 (Expand_Inline_Call): If an actual is a literal, and the corresponding
6088 formal has its address taken in the body, create a temporary to capture
6089 value. If the return type is a limited interface, do not treat the
6090 return value as Controlled.
6091 (Is_In_Place_Function): If the return type is a limited interface,
6092 treat as returning in place. The actual returned object may not always
6093 be limited, but the caller has to assume that it is returned in place.
6094 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
6095 context of an allocator, use the correct finalization chain (that is,
6096 the chain belonging to the access type, rather than the chain belonging
6097 to the current scope).
6098 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
6099 result type rather than a controlling result as a precondition for
6100 adding an allocation form actual to a build-in-place call.
6101 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
6102 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
6103 primitive in the dispatch tables. This work is now done by Make_DT when
6105 (Register_Predefined_DT_Entry): Removed.
6106 (Add_Return): If end label is not present, use sloc of last statement
6107 for generated return statement in procedure, for better gdb behavior
6109 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
6110 object address nodes to ensure proper processing by routines like
6112 (Expand_Call): Fix generation of validity check for parameter
6113 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
6114 the allocation form parameter if the result subtype is constrained,
6115 except when the function has a controlling result.
6116 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
6117 rather than Is_Controlled and Has_Controlled_Component, since we want to
6118 include class-wide result types in this treatment. Also test for a
6119 controlling result, since that also requires passing a finalization
6121 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
6122 even when the result subtype is constrained, to handle calls involving
6123 controlling results.
6124 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
6125 is now called even when the result subtype is constrained, to handle
6126 calls involving controlling results.
6127 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
6128 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
6129 now performs the test).
6130 (Make_Build_In_Place_Call_In_Object_Declaration):
6131 Add_Alloc_Form_Actual_* is now called even when the result subtype is
6132 constrained, to handle calls involving controlling results.
6133 (Add_Return): Accomodate rewritten pattern from local raise to goto
6134 transformation, so that we still recognize an transfer statement
6135 and do the right thing here in that case.
6136 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
6137 and end of subprogram code.
6138 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
6139 support for primitives that are functions (without formals) with a
6141 (Inherited_From_Formal): If the actual subtype has not generic parent
6142 type, it is not an actual for a formal derived type, and there is no
6143 operation to inherit from the formal.
6145 2007-06-06 Ed Schonberg <schonberg@adacore.com>
6146 Thomas Quinot <quinot@adacore.com>
6148 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
6149 inserted cleanup code appropriately for GDB use.
6150 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
6151 exception handler for Deep_Adjust or Deep_Finalize.
6152 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
6153 Raise_From_Controlled_Operation is available, use a call to that
6154 subprogram instead of a plain "raise Program_Error" node to raise
6155 Program_Error if an exception is propagated from an Adjust or Finalize
6157 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
6158 appears in the optional statement list of a triggering alternative, the
6159 scope actions can be inserted directly there, and not in the list that
6160 includes the asynchronous select itself.

6166 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
6167 generated exception handler appropriately when debugging generated code.
6168 Deal properly with No_Exception_Propagation restriction mode.
6169 (Expand_N_Abort_Statement): Add an unchecked type conversion from
6170 System.Address to System.Tasking.Task_Id when processing the result of
6171 the predefined primitive _disp_get_task_id.
6172 (Expand_N_Asynchronous_Select): Clarify comment.
6173 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
6174 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
6175 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
6176 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
6177 privals and for generated call to Complete_Entry_Body, for better gdb
6179 (Copy_Result_Type): Utility to construct a parameter and result profile
6180 for protected functions whose return type is an anonymous access to
6182 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
6184 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
6185 point when the local-raise-to-goto transformation has taken place.
6187 2007-06-06 Javier Miranda <miranda@adacore.com>
6188 Nicolas Setton <setton@adacore.com>
6190 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
6191 functionality when the backend is generating code.
6192 Otherwise any serious error
6193 reported by the backend calling the frontend routine Error_Msg
6194 changes the Compilation_Mode to Check_Semantics, disables the
6195 functionality of this routine and causes the generation of
6196 spureous additional errors.
6198 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
6199 debugging information now generated by the compiler for fat-pointer
6201 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
6203 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
6205 2007-06-06 Thomas Quinot <quinot@adacore.com>
6207 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
6208 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
6209 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
6210 For a remote call to a function with a classwide return type, apply an
6211 E.4(18) check to the returned value.
6212 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
6213 stream attributes of the designated type of an RACW, as they are not
6214 dispatching primitive operations.
6216 2007-06-06 Geert Bosch <bosch@adacore.com>
6218 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
6220 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
6222 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
6223 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
6225 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
6227 2007-06-06 Javier Miranda <miranda@adacore.com>
6229 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
6230 attribute compiling package Ada.Tags under No_Run_Time_Mode.
6232 2007-06-06 Javier Miranda <miranda@adacore.com>
6234 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
6235 deallocation of class-wide interface objects.
6236 (Expand_Dispatching_Constructor_Call): Take into account that if the
6237 result of the dispatching constructor is an interface type, the
6238 function returns a class-wide interface type; otherwise the returned
6239 object would be actual. The frontend previously accepted returning
6240 interface types because Expand_Interface_Actuals silently performed
6241 the management of the returned type "as if" it were a class-wide
6243 (Expand_Dispatching_Constructor_Call): Replace call to
6244 Make_DT_Access_Action by direct call to Make_Function_Call.

6247 Ed Schonberg <schonberg@adacore.com>
6249 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
6250 compute masking constant, since we now set Esize properly to the
6252 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
6253 to match the alignment.
6254 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
6255 packed arrays of 8 bits or less.
6257 * freeze.adb (Freeze_Entity): When freezing the formals of a
6258 subprogram, freeze the designated type of a parameter of an access type
6259 only if it is an access parameter.
6260 Increase size of C convention enumeration object
6261 (Freeze_Entity, array type case): Make sure Esize value is properly
6262 adjusted for the alignment if it is known.
6263 (Freeze_Entity, array type case): When checking bit packed arrays for
6264 the size being incorrect, check RM_Size, not Esize.
6265 (Freeze_Record_Type): Check for bad discriminated record convention
6266 (In_Exp_Body): Return true if the body is generated for a subprogram
6267 renaming, either an attribute renaming or a renaming as body.
6268 (Check_Itype): If the designated type of an anonymous access component
6269 is a non-protected subprogram type, indicate that it is frozen, to
6270 prevent out-of-scope freeze node at some subsequent call.
6271 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
6272 only if the subprogram is neither imported nor exported, as well as the
6273 NCA descriptor class if the subprogram is exported.

8201 to handle properly the anonymous access case.
8203 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
8204 for all access attributes, because overload resolution should work the
8205 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
8206 causes the error message for the ambiguous "X'Access = Y'Access" and
8207 "X'Unrestricted_Access = Y'Access" and so forth to match.
8208 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
8209 now that anonymous access to protected operations have their own kind.

8222 Derived_Type for Prev formal on call to
8223 Check_Anonymous_Access_Components rather than Empty.
8224 (Make_Incomplete_Type_Declaration): Add test for case where the type has
8225 a record extension in deciding whether to create a class-wide type,
8226 rather than just checking Tagged_Present.

8239 to complete the decoration of synchronized interface types. Add also
8240 a call to Check_Abstract_Interfaces to verify the ARM rules.
8241 (Derive_Interface_Subprograms): Modified to support concurrent types
8242 with abstract interfaces.

8270 Do not collect arguments if project is externally built.
8271 (Compile_Sources): Do nothing, not even check if the source is up to
8272 date, if its project is externally built.
8273 (Compile): When compiling a predefined source, add -gnatpg
8274 as the second switch, after -c.
8275 (Compile_Sources): Allow compilation of Annex J renames without -a
8276 (Is_In_Object_Directory): Check if the ALI file is in the object
8277 even if there is no project extension.
8278 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
8279 gnatbind if the ALI file effectively exists.
8280 (Initialize): Add the directory where gnatmake is invoked in front of
8281 the path if it is invoked from a bin directory, even without directory
8282 information, so that the correct GNAT tools will be used when spawned
8283 without directory information.

8306 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
8307 when -gnatg is not specified.
8308 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
8309 there is no need to generate always a record_definition_node in case
8310 of synchronized interface types.
8311 (SIS_Entry_Active): Initialize global variable to False
8312 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to
8313 indicate cases where AI-447 says "not null" is legal.

8337 (Convert_Aggr_In_Allocator): If the allocator is for an access
8338 discriminant and the type is controlled. do not place on a finalization
8339 list at this point. The proper list will be determined from the

8342 initialize record controller if needed, before the components, to ensure
8343 that they are properly finalized.

8357 same scope level as the allocator's type. The check is guaranteed to
8358 succeed in that case, even when the expression originates from a
8359 parameter of the containing subprogram.
8360 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
8361 under No_Dispatching_Calls restriction. During the semantic analysis
8362 we already notified such violation.
8363 (Tagged_Membership): Constant folding. There is no need to check
8364 the tag at run-time if the type of the right operand is non
8365 class-wide abstract.

8379 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
8380 initialize most the TSD components by means of an aggregate.
8381 Modify the declaration of the object containing the TSD
8382 because we now expand code that has a higher level of abstraction.
8383 The TSD has a discriminant containing the Inheritance Depth Level,
8384 value that is used in the membership test but also to fix the size
8385 of the table of ancestors.
8386 (Expand_Interface_Conversion): Insert function body at the closest place
8387 to the conversion expression, to prevent access-before-elaboration
8388 errors in the backend.

8429 returns an actual parameter expression for both named and positional
8432 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
8433 check violation of restriction No_Dispatching_Calls.
8434 (Check_Controlling_Type): A formal of a tagged incomplete type is a
8435 controlling argument.

8438 First/Next_Component_Or_Discriminant
8439 (Insert_Actions): Add entries for new N_Push and N_Pop nodes

8443 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
8444 support concurrent types implementing interfaces.
8445 (Find_Implemented_Interface): Removed. All the calls to this subprogram

8449 CW_Or_Controlled_Type whenever the issue is related to
8450 using or not the secondary stack.
8452 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
8453 P_Interface_Type_Definition to fulfill the new interface (the formal
8454 Is_Synchronized is no longer required).

8466 anonymous, use finalization list of enclosing dynamic scope.
8467 (Expand_N_Package_Declaration): For a library package declaration
8468 without a corresponding body, generate RACW subprogram bodies in the
8469 spec (just as we do for the task activation call).

8471 Is_Abstract_Type. Make sure these are called only when appropriate.

8490 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
8491 a protected version of an operation declared in the private part of
8492 a protected object, because they may be invoked through a callback.
8493 (Set_Privals): If the type of a private component is an anonymous access
8494 type, do not create a new itype for each protected body.
8495 If the body of a protected operation creates
8496 controlled types (including allocators for class-widetypes), the
8497 body of the corresponding protected subprogram must include a

8520 parameter that requires an extra constrained parameter, declare
8521 temporary for actual as a variable, not a constant.
8522 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
8523 the unit being compiled is the one that contains the stub type.

8528 (Append_RACW_Bodies): New subprogram.
8529 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to

8536 registering the receiving stubs at the end of the 'Stmts' list.
8537 (RCI_Package_Locator): Pass the new Version generic formal when
8538 instantiating a RCI_Locator package.
8539 (Build_From_Any_Function): To compute the High bound for an
8540 unconstrained array actual, we add the Low bound with the length.
8541 Thus we must convert the low bound and the length to an appropriate
8542 type before doing the sum.
8543 (Build_Subprogram_Receiving_Stubs, PolyORB):
8544 * Retrieve the extra formals parameters at the
8545 end of the parameter stream.
8546 * Use Move_Any_Value to write back out parameters
8547 after executing the request as it is more efficient
8548 than Copy_Any_Value.
8549 * Build the any containing Extra Formals with the
8550 appropriate typecode.
8551 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
8552 empty Component_List.

8565 function with the first not implicit parent type.
8566 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
8567 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
8568 typecode from the Etype. Therefore we retrieve the correct typecode
8569 with a call to Get_Any_Type.
8570 (Copy_Specification): Do controlling formal type substitution based on
8571 Is_Controlling_Formal flag, instead of caller-provided object type.
8572 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
8573 a RACW primitive operation, we might get a subprogram declaration for an
8574 ancestor of the RACW designated type (not for the designated type
8575 itself), in the case where this operation is inherited. In this case we
8576 have no easy means of determining the original tagged type for which
8577 the primitive was declared, so instead we now rely on
8578 Copy_Specification to use the Is_Controlling_Formal flag to determine
8579 which formals require type substitution.

8589 run-time subprogram CW_Membership by call to Build_CW_Membership.
8590 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
8591 by a function call, a temporary must be created before expanding the
8592 Constructor_Call itself, to prevent out-of-order elaboration in the
8593 back-end when stack checking is enabled..

8670 the .ci files belonging to the projects, including binder generated
8672 (Non_VMS_Usage): Document that gnatstack accept project file switches.
8673 (GNATCmd): Update the B_Start variable if we are in a VMS environment.
8674 Add gnatstack to the list of commands that use project file related

8725 This set of patch add support for the encoding form parameter.
8726 (S2WS): Improve implementation to handle cases where the filename is not

8775 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
8776 __gnat_adjust_context_for_raise.
8777 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
8778 implementation of floating point operations as native x86 targets.
8779 So the FPU should be initialized in the same way using finit. Fix
8780 floating point operations accuracy issues.
8781 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
8782 member in struct sigaction, so as to avoid warning for incompatible

8801 Modify the loop that collects type references, to include interface
8802 types that the type implements. List each of these interfaces when
8803 building the entry for the type.
8804 (Generate_Definition): Initialize component Def and Typ of new entry
8805 in table Xrefs, to avoid to have these components unitialized.
8806 (Output_References): Split Is_Abstract flag into

8849 2007-04-06 Robert Dewar <dewar@adacore.com>
8851 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
8852 it no longer destroys the contents of Name_Buffer or Name_Len and
8853 non-standard and invalid names are handled better.
8854 (Get_Decoded_Name_String): Improve performance by using
8855 Name_Has_No_Encodings flag in the name table.
8856 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
8857 Used for debugging printouts.
8859 2007-04-06 Robert Dewar <dewar@adacore.com>

8868 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
8869 illegal in Ada 95, in cases where it is legal. Change the warnings to
8870 errors in other cases. Don't give the error unless the "not null"
8871 parses properly. Correct the source position at which the error occurs.
8872 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
8873 P_Null_Exclusion, to suppress "not null" warnings.

9008 * sem_ch10.adb (Install_Limited_Context_Clauses.
9009 Expand_Limited_With_Clause): Use a new copy of selector name in the
9010 call to Make_With_Clause. This fixes the tree structure for ASIS
9011 purposes. Nothing is changed in the compiler behaviour.

9014 (Install_Limited_With_Clauses): Do not install non-limited view when it
9015 is still incomplete.
9017 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9018 Gary Dismukes <dismukes@adacore.com>
9020 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
9021 when capturing size information, instead of base type, which for a
9022 formal array type will be the unconstrained type.
9023 (Analyze_Formal_Object_Declaration): Add check for illegal default
9024 expressions for a formal in object of a limited type.
9025 (Instantiate_Object): Ditto.
9026 (Check_Formal_Package_Instance): Skip entities that are formal objects,
9027 because they were defaulted in the formal package and no check applies
9029 (Check_Formal_Package_Instance): Extend conformance check to other
9030 discrete types beyond Integer.
9031 (Process_Default): Copy directly the unmatched formal. A generic copy
9032 has already been performed in Analyze_Formal_Package.
9033 (Analyze_Associations): If a formal subprogram has no match, check for
9034 partial parametrization before looking for a default, to prevent
9036 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
9037 not set the instantiation environment before analyzing the actuals.
9038 Fixes regression on 8515-003 with implementation of AI-133.
9039 Set_Instance_Env checks whether the generic unit is a predefined
9040 unit, in which case the instance must be analyzed with the latest Ada
9041 mode. This setting must take place after analysis of the actuals,
9042 because the actuals must be analyzed and frozen in the Ada mode extant
9043 outside of the current instantiation.
9044 (Save_Env, Restore_Env): Preserve and restore the configuration
9045 parameters so that predefined units can be compiled in the proper Ada
9047 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
9048 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
9049 and Is_Abstract_Type.
9050 (Analyze_Formal_Package): For better error recovery, Add exception
9051 handler to catch Instantion_Error, which can be raised in
9052 Analyze_Associations
9054 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9055 Bob Duff <duff@adacore.com>
9056 Gary Dismukes <dismukes@adacore.com>
9058 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
9059 prefix type is a discriminated subtype of the type of the formal.
9060 (Analyze_Allocator): Collect all coextensions regardless of the context.
9061 Whether they can be allocated statically is determined in exp_ch4.
9062 (Analyze_Selected_Component): If the prefix is a limited view and the
9063 non-limited view is available, use the non-limited one.
9064 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
9065 therefore illegal), suggest a qualified expression rather than a type
9066 conversion, because a type conversion would be illegal in this context.
9067 (Anayze_Allocator): Trace recursively all nested allocators so that all
9068 coextensions are on the corresponding list for the root. Do no mark
9069 coextensions if the root allocator is within a declaration for a stack-
9070 allocated object, because the access discriminants will be allocated on
9072 (Analyze_Call): Remove restriction on calls to limited functions for the
9073 cases of generic actuals for formal objects, defaults for formal objects
9074 and defaults for record components.
9075 (Analyze_Allocator): Before analysis, chain coextensions on the proper
9076 element list. Their expansion is delayed until the enclosing allocator
9077 is processed and its finalization list constructed.
9078 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
9079 for an operation with the given name among the primitive operations of
9080 the corresponding record type.
9081 (Analyze_Selected_Component): If the prefix is a task type that
9082 implements an interface, and there is no entry with the given name,
9083 check whether there is another primitive operation (e.g. a function)
9085 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
9086 properly the indexing of a function call written in prefix form, where
9087 the function returns an array type, and all parameters of the function
9088 except the first have defaults.
9089 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
9090 the original operands, rather than relocating them, for efficiency and
9091 to work properly when an operand is overloaded.
9092 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
9093 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
9094 (Analyze_Selected_Component): If the prefix is a private extension, only
9095 scan the visible components, not those of the full view.
9096 (Try_Primitive_Operation): If the operation is a procedure, collect all
9097 possible interpretations, as for a function, because in the presence of
9098 classwide parameters several primitive operations of the type can match
9099 the given arguments.
9101 2007-04-06 Ed Schonberg <schonberg@adacore.com>
9102 Robert Dewar <dewar@adacore.com>
9104 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a

9110 Thomas Quinot <quinot@adacore.com>
9112 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
9113 out of Analyze_Package_Declaration, because processing must be applied
9114 to package bodies as well, for deferred constants completed by pragmas.
9115 (Analyze_Package_Declaration): When the package declaration being
9116 analyzed does not require an explicit body, call Check_Completion.
9117 (May_Need_Implicit_Body): An implicit body is required when a package
9118 spec contains the declaration of a remote access-to-classwide type.
9119 (Analyze_Package_Body): If the package contains RACWs, append the

9240 operation applies to a private type whose full view is a modular type.
9241 (Case_Statement_To_gnu): If an alternative is an E_Constant with an

9511 Add some \\ sequences to continuation messages
9512 (Resolve_Call): Refine infinite recursion case. The test has been

9528 Valid_Conversion, to incorporate accessibility checks for arrays of
9529 anonymous access types.
9530 (Valid_Conversion): For a conversion to a numeric type occurring in an
9531 instance or inlined body, no need to check that the operand type is
9532 numeric, since this has been checked during analysis of the template.

10048 (Set_All_DT_Position): Hidden entities associated with abstract
10049 interface primitives are not taken into account in the check for
10050 3.9.3(10); this check is done with the aliased entity.
10051 (Make_DT, Set_All_DT_Position): Enable full ABI compatibility for
10052 interfacing with CPP by default.
10053 (Expand_Interface_Conversion): Add missing support for static conversion

10056 abstract interface types to cleanup the subprogram Make_DT.
10057 (Make_DT): Update the code to generate the table of interfaces in case
10058 of abstract interface types.
10059 (Is_Predefined_Dispatching_Alias): New function that returns true if
10060 a primitive is not a predefined dispatching primitive but it is an
10061 alias of a predefined dispatching primitive.
10062 (Make_DT): If the ancestor of the type is a CPP_Class and we are
10063 compiling under full ABI compatibility mode we avoid the generation of
10064 calls to run-time services that fill the dispatch tables because under
10065 this mode we currently inherit the dispatch tables in the IP subprogram.
10066 (Write_DT): Emit an "is null" indication for a null procedure primitive.
10067 (Expand_Interface_Conversion): Use an address as the type of the formal
10068 of the internally built function that handles the case in which the
10069 target type is an access type.

10102 by themselves. Disabling those checks must also be done for task types,
10103 where discriminants may be used for the bounds of entry families.
10104 (Apply_Address_Clause_Check): Remove side-effects if address expression
10105 is non-static and is not the name of a declared constant.

10117 rewritten replacement for Apply_Alignment_Check
10118 (Get_E_Length/Get_E_First_Or_Last): Add missing barrier to ensure that
10119 we request a discriminal value only in case of discriminants.
10120 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
10121 assignments where the target subtype is unconstrained and the target
10122 object is a parameter or dereference (other aliased cases are known
10123 to be unconstrained).

10149 (Is_Return_By_Reference_Type): Rename Is_Return_By_Reference_Type
10150 to be Is_Inherently_Limited_Type, because return-by-reference has

10238 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
10239 are build-in-place function calls.
10240 (Replace_Self_Reference): New subsidiary of
10241 Make_OK_Assignment_Statement, to replace an access attribute that is a
10242 self-reference into an access to the appropriate component of the
10243 target object. Generalizes previous mechanism to handle self-references
10244 nested at any level.
10245 (Is_Self_Referential_Init): Remove, not needed.
10246 (Is_Self_Referential_Init): New predicate to simplify handling of self
10247 referential components in record aggregates.

10249 check for presence of entity before checking for self-reference.
10250 (Has_Default_Init_Comps): Return True if a component association is a
10251 self-reference to the enclosing type, which can only come from a
10252 default initialization.
10253 (Make_OK_Assignment_Statement): If the expression is of the form
10254 Typ'Acc, where Acc is an access attribute, the expression comes from a
10255 default initialized self-referential component.
10256 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
10257 that has been derived from several abstract interfaces we must also
10258 initialize the tags of the secondary dispatch tables.

10262 Javier Miranda <miranda@adacore.com>
10263 Robert Dewar <dewar@adacore.com>
10266 (Expand_Access_To_Protected_Op): If the context indicates that an access
10267 to a local operation may be transfered outside of the object, create an
10268 access to the wrapper operation that must be used in an external call.
10269 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
10270 target, pass the Valid attribute applied to a floating-point prefix on
10271 to the back end without expansion.
10272 (Storage_Size): Use the new run-time function Storage_Size to retrieve
10273 the allocated storage when it is specified by a per-object expression.
10274 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
10275 Nothing to do here, the attribute has been rewritten during semantic

10284 into a fat pointer.
10285 (Is_Constrained_Aliased_View): New predicate to help determine whether a
10286 subcomponent's enclosing variable is aliased with a constrained subtype.
10287 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
10288 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
10289 an aliased prefix must be known to be constrained in order to use True
10290 for the attribute value, and now it's possible for some aliased views
10291 to be unconstrained.
10293 2006-10-31 Robert Dewar <dewar@adacore.com>
10295 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
10296 (Expand_Entity_Reference): Correct error of not handling subprogram
10297 formals in current_value processing.

10304 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
10305 register in the final list objects containing class-wide interfaces;
10306 otherwise we incorrectly register the tag of the interface in the final
10308 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
10309 generate the wrapper if the parent primitive is abstract. This is
10310 required to report the correct error message.
10311 (Expand_N_Subtype_Indication): Do validity checks on range
10312 (Clean_Task_Names): If an initialization procedure includes a call to
10313 initialize a task (sub)component, indicate that the procedure will use
10314 the secondary stack.
10315 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
10316 compatibility for interfacing with CPP by default.
10317 (Expand_N_Object_Declaration): Only build an Adjust call when the
10318 object's type is a nonlimited controlled type.
10319 * exp_ch3.adb: Add with and use of Exp_Ch6.
10320 (Expand_N_Object_Declaration): Check for object initialization that is a
10321 call to build-in-place function and apply Make_Build_In_Place_Call_In_
10322 Object_Declaration to the call.
10323 (Freeze_Type): When the designated type of an RACW was not frozen at the
10324 point where the RACW was declared, validate the primitive operations
10325 with respect to E.2.2(14) when it finally is frozen.
10326 (Build_Initialization_Call,Expand_Record_Controller): Rename
10327 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
10328 return-by-reference has no meaning in Ada 2005.
10329 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
10330 to register tag of the immediate ancestor interfaces in the
10331 run-time structure.
10332 (Init_Secondary_Tags): Moved to the specification to allow the
10333 initialization of extension aggregates with abstract interfaces.
10334 (Build_Master_Renaming): Make public, for use by function declarations
10335 whose return type is an anonymous access type.
10336 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
10337 Insert_List_Before_And_Analyze after the generation of the specs
10338 associated with null procedures.
10339 (Expand_Tagged_Root): Update documentation in its specification.
10340 (Init_Secondary_Tags): Update documentation.
10341 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
10342 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
10343 then generate code to inherit the contents of the dispatch table
10344 directly from the ancestor.
10345 (Expand_Record_Controller): Insert controller component after tags of
10346 implemented interfaces.
10347 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
10348 create null procedure overridings when null procedures are inherited
10350 (Make_Null_Procedure_Specs): New procedure to generate null procedure
10351 declarations for overriding null primitives inherited from interfaces.
10352 (Is_Null_Interface_Procedure): New function in
10353 Make_Null_Procedure_Specs.
10354 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
10355 immediate ancestor of a tagged type is an abstract interface type we
10356 must generate the specification of the predefined primitives associated
10357 with controlled types (because the dispatch table of the ancestor is
10358 null and hence these entries cannot be inherited). This is required to
10359 elaborate well the dispatch table.

10369 (Expand_N_In): Do validity checks on range
10370 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
10371 (Expand_N_Allocator): For "new T", if the object is constrained by
10372 discriminant defaults, allocate the right amount of memory, rather than
10373 the maximum for type T.
10374 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
10375 when the allocator is initialized by a build-in-place call, since the
10376 allocator is already rewritten as a reference to the function result,
10377 and this prevents an unwanted duplication of the function call.
10378 Add with and use of Exp_Ch6.
10379 (Expand_Allocator_Expresssion): Check for an allocator whose expression
10380 is a call to build-in-place function and apply
10381 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
10382 untagged designated types).
10383 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
10384 optimization if source or target is biased.
10385 (Expand_N_Allocator): Add comments for case of an allocator within a
10386 function that returns an anonymous access type designating tasks.
10387 (Expand_N_Allocator): apply discriminant checks for access
10388 discriminants of anonymous access types (AI-402, AI-416)

10397 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
10398 (Expand_N_Assignment_Statement): Call
10399 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
10400 build-in-place function call. Currently, this can happen only for
10401 assignments that come from aggregates.
10402 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
10403 in order to alleviate the upward compatibility introduced by AI-318.
10404 (Expand_N_Extended_Return_Statement): Add support for handling the
10405 return object as a build-in-place result.
10406 (Expand_Non_Function_Return): Implement simple return statements nested
10407 within an extended return.
10408 (Enable_New_Return_Processing): Turn on the new processing of return
10410 (Expand_Non_Function_Return): For a return within an extended return,
10411 don't raise Program_Error, because Sem_Ch6 now gives a warning.
10412 (Expand_N_Extended_Return_Statement): Implement AI-318
10413 (Expand_Simple_Function_Return): Ditto.
10414 (Expand_N_If_Statement): Handle new -gnatwt warning
10415 (Expand_N_Case_Statement): Handle new -gnatwt warning
10416 (Expand_N_Assignment): Handle assignment to the Priority attribute of
10417 a protected object.
10418 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
10419 validity checking of assignments to elementary record components.
10420 (Expand_N_Return_Statement): return Class Wide types on the secondary
10421 stack independantly of their controlled status since with HIE runtimes,
10422 class wide types are not potentially controlled anymore.
10424 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
10427 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
10428 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
10429 it expects a block, procedure, or task. The return statement will get
10430 turned into a block, and Expand_Cleanup_Actions will happen then.

10434 Bob Duff <duff@adacore.com>
10435 Gary Dismukes <dismukes@adacore.com>
10437 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
10439 (Expand_Inlined_Call): Tagged types are by-reference types, and
10440 therefore should be replaced by a renaming declaration in the expanded
10441 body, as is done for limited types.
10442 (Expand_Call): If this is a call to a function with dispatching access
10443 result, propagate tag from context.
10444 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
10446 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
10447 build-in-place when the right-hand side of an assignment is a
10448 build-in-place function call.
10449 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
10450 of the explicit dereference of the allocator to the result subtype of
10451 the build-in-place function. This is needed to satisfy type checking
10452 in cases where the caller's return object is created by an allocator for
10453 a class-wide access type and the type named in the allocator is a
10455 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
10456 conversion of the reference to the declared object to the result subtype
10457 of the build-in-place function. This is needed to satisfy type checking
10458 in cases where the declared object has a class-wide type. Also, in the
10459 class-wide case, change the type of the object entity to the specific
10460 result subtype of the function, to avoid passing a class-wide object
10461 without explicit initialization to the back end.
10462 (Register_Interface_DT_Entry): Moved outside the body of
10463 Freeze_Subprogram because this routine is now public; it is called from
10464 Check_Dispatching_Overriding to handle late overriding of abstract
10465 interface primitives.
10466 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
10467 adding an implicit access actual on a call to a build-in-place function.

10470 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
10471 (Is_Build_In_Place_Function): New function to determine whether an
10472 entity is a function whose calls should be handled as build-in-place.
10473 (Is_Build_In_Place_Function_Call): New function to determine whether an
10474 expression is a function call that should handled as build-in-place.
10475 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
10476 calls to build-in-place functions as the initialization of an allocator.
10477 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
10478 handling calls to build-in-place functions in contexts that do not
10479 involve init of a separate object (for example, actuals of subprogram
10481 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
10482 handling calls to build-in-place functions as the initialization of an
10483 object declaration.

10490 inlined statements if within a transient scope.
10491 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
10492 formal parameters with occurrences of actuals in inlined body, establish
10493 visibility on the proper view of the actual's subtype for the body's
10495 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
10496 compatibility mode and we have an imported CPP subprogram because
10497 for now we assume that imported CPP primitives correspond with
10498 objects whose constructor is in the CPP side (and therefore we
10499 don't need to generate code to register them in the dispatch table).
10500 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
10501 aligned selected component.
10502 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
10503 the actual of an in-mode parameter is a type conversion.
10504 (Expand_Actuals): If the call does not come from source and the actual
10505 is potentially misaligned, let gigi handle it rather than rejecting the
10506 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
10507 Class Wide types as returning by reference independantly of their
10508 controlled status since with HIE runtimes class wide types are not
10509 potentially controlled anymore.

10531 Pablo Oliveira <oliveira@adacore.com>
10533 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
10534 subprogram Ids, even if they are not yet assigned.
10535 (Build_Subprogram_Id): It is now this function that will take care of
10536 calling Assign_Subprogram_Ids if necessary.
10537 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
10538 should be done only once they are assigned.
10539 (Build_From_Any_Function, case of tagged types): Add missing call to
10541 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
10542 type for an RACW type.
10543 (Add_RACW_Features): When processing an RACW declaration for which the
10544 designated type is already frozen, enforce E.2.2(14) rules immediately.
10545 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
10546 special reordering of controlling formals.
10548 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
10549 associated stub type for an RACW type.

10553 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
10554 fixed-point operations in an integer context, i.e. as operands of a
10555 conversion to an integer type, indicate that result must be rounded.
10557 2006-10-31 Robert Dewar <dewar@adacore.com>
10559 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
10560 cases, pass the encoding method, since it is now required by the run
10563 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
10564 assumption that Str'First = 1.
10565 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
10566 it on to the Value_Wide_Wide_Character call.
10567 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
10568 properly handles a string of the form quote-encoded_wide_char-quote.
10570 * s-wchcnv.adb: Minor reformatting
10572 2006-10-31 Javier Miranda <miranda@adacore.com>
10574 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
10575 run-time membership test to ensure that the constructed object
10576 implements the target abstract interface.
10578 2006-10-31 Robert Dewar <dewar@adacore.com>
10580 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
10581 Machine_Attribute pragma internally to implement the user pragma.
10582 Add processing for pragma Interface so that it is now completely
10583 equivalent to pragma Import.
10585 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
10586 so that it can be applied to all entities, including record components
10587 and enumeration literals.
10588 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
10589 priority ranges are correct, verify compatibility against task
10590 dispatching and locking policies, and if everything is correct an entry
10591 is added to the table containing priority specific dispatching entries
10592 for this compilation unit.
10593 (Delay_Config_Pragma_Analyze): Delay processing
10594 Priority_Specific_Dispatching pragmas because when processing the
10595 pragma we need to access run-time data, such as the range of
10596 System.Any_Priority.
10597 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
10598 Allow pragma Unreferenced as a context item
10599 Add pragma Preelaborable_Initialization
10600 (Analyze_Pragma, case Interface): Interface is extended so that it is
10601 now syntactically and semantically equivalent to Import.
10602 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
10603 insertion characters.
10604 Add handling for Pragma_Wide_Character_Encoding
10605 (Process_Restrictions_Restriction_Warnings): Ensure that a warning

10615 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
10616 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
10617 Is_Inherently_Limited_Type, because return-by-reference has no meaning
10619 (Find_Node_To_Be_Wrapped): Use new method of determining the result
10620 type of the function containing a return statement, because the
10621 Return_Type field was removed. We now use the Return_Applies_To field.
10623 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
10624 (Build_Task_Image_Decl): If procedure is not called from an
10625 initialization procedure, indicate that function that builds task name
10626 uses the sec. stack. Otherwise the enclosing initialization procedure
10627 will carry the indication.
10628 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
10629 N_Object_Declaration instead.
10630 (Kill_Dead_Code): New interface to implement -gnatwt warning for
10631 conditional dead code killed, and change implementation accordingly.
10632 (Insert_Actions): Add N_Return_Object_Declaration case.
10633 Correct comment to mention N_Extension_Aggregate node.

10635 attempts to save information for global variables which cannot be
10637 (Get_Current_Value_Condition): Handle conditions the other way round
10638 (constant on left). Also handle right operand of AND and AND THEN

10640 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
10641 (Get_Current_Value_Condition): Handle simple boolean operands
10642 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
10643 (Get_Current_Value_Condition): If the variable reference is within an
10644 if-statement, does not appear in the list of then_statments, and does
10645 not come from source, treat it as being at unknown location.
10646 (Get_Current_Value_Condition): Enhance to allow while statements to be
10647 processed as well as if statements.
10648 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
10650 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
10651 of loop. This is safe now that we fixed Kill_Current_Values.
10652 (OK_To_Do_Constant_Replacement): Check whether current scope is
10653 Standard, before examining outer scopes.
10655 2006-10-31 Vincent Celier <celier@adacore.com>

10675 (Generate_Reference): Centralize handling of pragma Obsolescent here
10676 (Generate_Reference): Accept an implicit reference generated for a
10677 default in an instance.
10678 (Generate_Reference): Accept a reference for a node that is not in the
10679 main unit, if it is the generic body corresponding to an subprogram
10682 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings

10688 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
10689 use clauses, to avoid messages on packages used to qualify, and also
10690 to avoid messages from obsolescent units.
10691 (Warn_On_Useless_Assignments): Don't generate messages for imported
10692 and exported variables.
10693 (Warn_On_Useless_Assignments): New procedure

10703 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
10704 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.

10707 Robert Dewar <dewar@adacore.com>
10708 Ed Schonberg <schonberg@adacore.com>
10710 * g-awk.adb (Default_Session, Current_Session): Compile this file in
10711 Ada 95 mode, because it violates the new rules for AI-318.
10713 * g-awk.ads: Use overloaded subprograms in every case where we used to
10714 have a default of Current_Session. This makes the code closer to be
10715 correct for both Ada 95 and 2005.
10717 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
10718 code, relying on the fact that the compiler generates a warning
10719 instead of an error in -gnatg mode.
10721 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
10722 E_Return_Statement entity kind.
10723 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
10725 * par.adb (P_Interface_Type_Definition): Addition of one formal to
10726 report an error if the reserved word abstract has been previously found.
10727 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
10729 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
10730 parenthesized range attribute usage
10731 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
10733 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
10734 in the syntax for extended_return_statement. This is not in the latest
10735 RM, but the ARG is expected to issue an AI allowing this.
10736 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
10737 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
10738 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
10739 P_Return_Statement): Parse the new syntax for extended_return_statement.
10741 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
10742 Output_End_Missing): Add error-recovery code for the new
10743 extended_return_statement syntax; that is, the new E_Return entry on
10746 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
10747 limited to nonlimited, because otherwise we violate the new Ada 2005
10748 rules about returning limited types in function Create_AST_Handler in
10751 * sem.adb (Analyze): Add cases for new node kinds
10752 N_Extended_Return_Statement and N_Return_Object_Declaration.
10754 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
10755 type is in the same category as type of context before applying check,
10756 to prevent anomalies in instantiations.
10757 (Resolve_Aggregate): Remove test for limited components in aggregates.
10758 It's unnecessary in Ada 95, because if it has limited components, then
10759 it must be limited. It's wrong in Ada 2005, because limited aggregates
10761 (Resolve_Record_Aggregate): Move check for limited types later, because
10762 OK_For_Limited_Init requires its argument to have been resolved.
10763 (Get_Value): When copying the component default expression for a
10764 defaulted association in an aggregate, use the sloc of the aggregate
10765 and not that of the original expression, to prevent spurious
10766 elaboration errors, when the expression includes function calls.
10767 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
10768 were missing. We also didn't handle qualified expressions. Now also
10769 allow function calls. Use new common routine OK_For_Limited_Init.
10770 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
10771 with space can upper case letter).
10773 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
10774 Has_Static_Discriminants flag
10775 (Record_Type_Declaration): Diagnose an attempt to declare an interface
10776 type with discriminants.
10777 (Process_Range_Expr_In_Decl): Do validity checks on range
10778 (Build_Discriminant_Constraints): Use updated form of
10779 Denotes_Discriminant.
10780 (Process_Subtype): If the subtype is a private subtype whose full view
10781 is a concurrent subtype, introduce an itype reference to prevent scope
10783 (Build_Derived_Record_Type, Collect_Interface_Primitives,
10784 Record_Type_Declaration): The functionality of the subprograms
10785 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
10786 is now performed by a single routine.
10787 (Build_Derived_Record_Type): If the type definition includes an explicit
10788 indication of limitedness, then the type must be marked as limited here
10789 to ensure that any access discriminants will not be treated as having
10790 a local anonymous access type.
10791 (Check_Abstract_Overriding): Issue a detailed error message when an
10792 abstract subprogram was not overridden due to incorrect mode of its
10794 (Analyze_Private_Extension_Declaration): Add support for the analysis of
10795 synchronized private extension declarations. Verify that the ancestor is
10796 a limited or synchronized interface or in the generic case, the ancestor
10797 is a tagged limited type or synchronized interface and all progenitors
10798 are either limited or synchronized interfaces.
10799 Derived_Type_Declaration): Check for presence of private extension when
10800 dealing with synchronized formal derived types.
10801 Process_Full_View): Enchance the check done on the usage of "limited" by
10802 testing whether the private view is synchronized.
10803 Verify that a synchronized private view is completed by a protected or
10805 (OK_For_Limited_Init_In_05): New function.
10806 (Analyze_Object_Declaration): Move check for limited types later,
10807 because OK_For_Limited_Init requires its argument to have been resolved.
10808 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
10809 in order to alleviate the upward compatibility introduced by AI-318.
10810 (Constrain_Corresponding_Record): If the constraint is for a component
10811 subtype, mark the itype as frozen, to avoid out-of-scope references to
10812 discriminants in the back-end.
10813 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
10814 this subprogram against wrong sources.
10815 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
10816 discriminant of limited type completed with a protected type, when the
10817 discriminant is used to constrain a private component of the type, and
10818 expansion is disabled.
10819 (Find_Type_Of_Object): Do not treat a return subtype that is an
10820 anonymous subtype as a local_anonymous_type, because its accessibility
10821 level is the return type of the enclosing function.
10822 (Check_Initialization): In -gnatg mode, turn the error "cannot
10823 initialize entities of limited type" into a warning.
10824 (OK_For_Limited_Init): Return true for generated nodes, since it
10825 sometimes violates the legality rules.
10826 (Make_Incomplete_Declaration): If the type for which an incomplete
10827 declaration is created happens to be the currently visible entity,
10828 preserve the homonym chain when removing it from visibility.
10829 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
10830 inherited subprograms.
10831 (Access_Definition): If this is an access to function that is the return
10832 type of an access_to_function definition, context is a type declaration
10833 and the scope of the anonymous type is the current one.
10834 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
10835 incomplete subtype to the set of private dependents of the original
10837 (Constrain_Discriminated_Type): Emit an error message whenever an
10838 incomplete subtype is being constrained.
10839 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
10840 corresponding subtype of the full view of the original incomplete type.
10841 (Check_Incomplete): Properly detect invalid usage of incomplete types
10844 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>

10855 Robert Dewar <dewar@adacore.com>
10857 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
10858 handling executable extension manually and duplicating code.
10860 * make.adb: Implement new -S switch
10861 (Gnatmake): Use new function Osint.Executable_Name instead
10862 of handling executable extension manually.
10864 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
10865 is specified, the executable name ends with this suffix.
10866 Take advantage of Osint.Executable_Name instead of duplicating code.
10868 * switch-m.adb: Recognize new gnatmake -S switch
10870 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
10872 (Get_Target_Parameters): Set Executable_Extension_On_Target if
10875 * makeusg.adb: Add line for gnatmake -S switch
10877 2006-10-31 Vincent Celier <celier@adacore.com>
10879 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
10880 call it with -static-libgcc, as there are some platforms, such as
10881 Darwin, where one of these two switches is compulsory to link.
10883 2006-10-31 Vincent Celier <celier@adacore.com>
10885 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
10886 instead of ADA_PROJECT_PATH, for the project path.
10887 (Gnatls): When displaying the project path directories, use host dir
10890 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
10891 names in the project path, as absolute paths may correspond to
10892 multi-valued VMS logical names.
10894 2006-10-31 Vincent Celier <celier@adacore.com>
10896 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
10897 absolute path name.
10898 (Locate_Regular_File): Ditto
10899 (Change_Dir): Remove, no longer used
10900 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
10901 on Windows. Get it calling Get_Current_Dir.

10903 (Normalize_Pathname)[VMS]: Do not resolve directory names.
10904 (Pid_To_Integer): New function to convert a Process_Id to Integer
10906 2006-10-31 Thomas Quinot <quinot@adacore.com>
10908 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
10909 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
10911 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
10914 2006-10-31 Robert Dewar <dewar@adacore.com>

10923 2006-10-31 Robert Dewar <dewar@adacore.com>
10925 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
10927 (Layout_Variant_Record): Retrieve the discriminants from the entity
10928 rather than from the type definition, because in the case of a full
10929 type for a private type we need to take the discriminants from the
10931 (Layout_Component_List): When applying the Max operator to variants with
10932 a nonstatic size, check whether either operand is static and scale that
10933 operand from bits to storage units before applying Max.
10934 (Layout_Type): In VMS, if a C-convention access type has no explicit
10935 size clause (and does not inherit one in the case of a derived type),
10936 then the size is reset to 32 from 64.
10938 2006-10-31 Vincent Celier <celier@adacore.com>
10940 * lib-load.adb (Load_Unit): Skip the test for a unit not found when

10945 Eric Botcazou <ebotcazou@adacore.com>
10946 Arnaud Charlet <charlet@adacore.com>
10948 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
10949 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
10951 (a-except.o): Pass it to the compiler.
10952 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
10953 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
10954 a-calend-mingw.adb version.
10956 * Makefile.rtl: Added s-dsaser.
10957 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
10958 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
10959 Ada.Dispatching.Round_Robin.
10960 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
10962 * Make-lang.in: Remove all references to gt-ada-decl.h.
10963 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
10965 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
10966 Update dependencies.
10968 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
10970 2006-10-31 Vincent Celier <celier@adacore.com>
10972 * mlib-utl.adb (Initialized): Remove, no longer used
10973 (Initialize): Remove, no longer used
10974 (Ar): If Ar_Exec is null, get the location of the archive builder and,
10975 if there is one, the archive indexer. Fail if the archive builder cannot
10977 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
10980 2006-10-31 Ed Schonberg <schonberg@adacore.com>
10982 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
10983 Process_Body_Clauses): If the context of a body includes a use clause
10984 for P.Q then a with_clause for P in the same body is not redundant,
10985 even if the spec also has a with_clause on P.
10986 Add missing continuation mark to error msg
10987 (Build_Limited_Views): A limited view of a type is tagged if its
10988 declaration includes a record extension.
10989 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
10990 node, even if the subunit has errors. This avoids malfunction by
10991 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
10992 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
10993 generation of obsolescent messages for with statements (cannot do
10994 this too early, or we cannot implement avoiding the messages in the
10995 case of obsolescent units withing obsolescent units).
10996 (Install_Siblings): If the with_clause is on a remote descendant of
10997 an ancestor of the current compilation unit, find whether there is
10998 a sibling child unit that is immediately visible.
10999 (Remove_Private_With_Clauses): New procedure, invoked after completing
11000 the analysis of the private part of a nested package, to remove from
11001 visibility the private with_clauses of the enclosing package
11003 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
11004 now centralized in Generate_Reference.
11005 (Install_Limited_Context_Clauses): Remove superfluous error
11006 message associated with unlimited view visible through use
11007 and renamings. In addition, at the point in which the error
11008 is reported, we add the backslash to the text of the error
11009 to ensure that it is reported as a single error message.
11010 Use new // insertion for some continuation messages
11011 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
11012 to create implicit with_clause for parent unit mentioned in original
11013 limited_with_clause.
11014 (Install_Limited_With_Unit): Set entity of parent identifiers if the
11015 unit is a child unit. For ASIS queries.
11016 (Analyze_Subunit): If the subunit appears within a child unit, make all
11017 ancestor child units directly visible again.

11027 (P_Formal_Type_Definition, P_Formal_Derived_Type_Definition): Add
11028 support for synchronized derived type definitions.
11029 Add the new actual Abstract_Present to every call to
11030 P_Interface_Type_Definition.
11031 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
11032 a formal object declaration with an access definition or a subtype mark
11033 with a null exclusion.
11034 (P_Generic_Association): Handle association with box, and others_choice
11035 with box, to support Ada 2005 partially parametrized formal packages.
11037 2006-10-31 Robert Dewar <dewar@adacore.com>
11038 Javier Miranda <miranda@adacore.com>
11040 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
11041 (P_Type_Declaration): Remove barrier against the reserved word "limited"
11042 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
11043 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
11044 private extensions.
11045 (P_Type_Declaration): Add the new actual Abstract_Present to every call
11046 to P_Interface_Type_Definition.
11047 (P_Interface_Type_Definition): Addition of one formal to report an error
11048 if the reserved word abstract has been previously found.
11049 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
11050 object renaming declaration with an access definition or subtype mark
11051 with a possible null exclusion.
11053 * par-ch9.adb: Minor error msg fix
11055 * par-load.adb: Add missing continuation mark to error msg
11057 * par-tchk.adb: (Wrong_Token): Code cleanup, use concatenation
11059 2006-10-31 Vincent Celier <celier@adacore.com>
11061 * prj-dect.adb (Parse_Attribute_Declaration): Do not issue warning for
11062 unknown attribute in unknown package or in package that does not need
11064 (Parse_Package_Declaration): Do not issue warning for unknown package in
11067 2006-10-31 Vincent Celier <celier@adacore.com>
11069 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
11070 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
11073 2006-10-31 Vincent Celier <celier@adacore.com>
11075 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
11076 on VMS, change "__" to '.' before checking the name.
11077 (Record_Ada_Source): Always add the source file name in the list of
11078 of sources, even if it is not the first time, as it is for another
11080 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
11081 dot, instead of replacing only the first '_'.
11083 * prj-part.adb (Parse): Convert project file path to canonical form
11085 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
11086 extended, the project id of the project extending it is recorded in its
11087 data, even when it has already been processed as an imported project.
11089 2006-10-31 Robert Dewar <dewar@adacore.com>
11091 * repinfo.adb (List_Entities): Don't list entities from renaming
11094 2006-10-31 Arnaud Charlet <charlet@adacore.com>
11095 Robert Dewar <dewar@adacore.com>
11097 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
11098 only a restriction warning is active for the given restriction. This is
11099 desirable because we do not want to modify code in the case where only
11101 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
11102 causes overriding of real restrictions.
11103 Take advantage of new No_Restrictions constant.
11105 * raise.h: (__gnat_set_globals): Change profile.
11107 2006-10-31 Arnaud Charlet <charlet@adacore.com>
11109 * rtsfind.adb: Remove s-polint from comment as it exists no more.
11112 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
11113 Move all the entities in obsolete package System.PolyORB_Interface to
11114 System.Partition_Interface.
11115 (RE_Storage_Size): New function in System.Tasking.
11116 (RE_Get_Ceiling): New entity.
11117 (RE_Set_Ceiling): New entity.
11118 (RO_PE_Get_Ceiling): New entity.

11128 Thomas Quinot <quinot@adacore.com>
11129 Javier Miranda <miranda@adacore.com>
11130 Gary Dismukes <dismukes@adacore.com>
11132 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
11133 properly an attempt to apply Unchecked_Access to a protected operation.
11134 (OK_Self_Reference): New subprogram to check the legality of an access
11135 attribute whose prefix is the type of an enclosing aggregate.
11136 Generalizes previous mechanism to handle attribute references nested
11137 arbitrarily deep within the aggregate.
11138 (Analyze_Access_Attribute): An access attribute whose prefix is a type
11139 can appear in an aggregate if this is a default-initialized aggregate
11140 for a self-referential type.
11141 (Resolve_Attribute, case Access): Ditto.
11142 Add support for new implementation defined attribute Stub_Type.
11143 (Eval_Attribute, case Attribute_Stub_Type): New case.
11144 (Analyze_Attribute, case Attribute_Stub_Type): New case.
11145 (Stream_Attribute_Available): Implement using new subprogram from
11146 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
11147 Has_Specified_Stream_Attribute flag.
11148 Disallow Storage_Size and Storage_Pool for access to subprogram
11149 (Resolve_Attribute, case 'Access et al): Take into account anonymous
11150 access types of return subtypes in extended return statements. Remove
11151 accessibility checks on anonymous access types when Unchecked_Access is
11153 (Analyze_Attribute): Add support for the use of 'Class to convert
11154 a class-wide interface to a tagged type.
11155 Add support for the attribute Priority.
11156 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
11157 whether the designated type is discriminated with a constrained partial
11158 view and require static matching in that case.
11159 Add local variable Des_Btyp. The Designated_Type
11160 of an access to incomplete subtype is either its non-limited view if
11161 coming from a limited with or its etype if regular incomplete subtype.
11163 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
11164 Fix predicate to identify and allow cases of (expander-generated)
11165 references to tag of designated object of a RACW.
11166 (Validate_Static_Object_Name): In Ada 2005, a formal object is
11167 non-static, and therefore cannot appear as a primary in a preelaborable
11169 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
11170 Has_Read_Write_Attributes.
11171 (Has_Read_Write_Attributes): Reimplement in termes of
11172 Has_Stream_Attribute_Definition.
11173 (Missing_Read_Write_Attributes): When checking component types in a
11174 record, unconditionally call Missing_Read_Write_Attributes recursively
11175 (remove guard checking for Is_Record_Type / Is_Access_Type).
11177 2006-10-31 Robert Dewar <dewar@adacore.com>
11179 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
11180 useless assignments here and conditionalize it on absence of exception
11182 (Analyze_Exception_Handlers): Small code reorganization of error
11183 detection code, for new handling of formal packages.
11185 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11186 Hristian Kirtchev <kirtchev@adacore.com>
11188 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
11189 that has been constant-folded, preserve information of original tree,
11191 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
11192 generated private extension declaration if the formal derived type is
11193 synchronized. Carry synchronized present over to the generated private
11195 (Validate_Derived_Type_Instance): Ensure that the actual of a
11196 synchronized formal derived type is a synchronized tagged type.
11197 (Instantiate_Formal_Package): When creating the instantiation used to
11198 validate the actual package of a formal declared without a box, check
11199 whether the formal itself depends on a prior actual.
11200 (Instantiate_Formal_Subprogram): Create new entities for the defining
11201 identifiers of the formals in the renaming declaration, for ASIS use.
11202 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
11203 a renaming declaration or a subtype declaration for an actual in an
11204 instance, capture location information of declaration in generic, for
11206 (Instantiate_Formal_Package): Add comments on needed additional tests.
11207 AI-317 (partial parametrization) is fully implemented.
11208 (Validate_Private_Type_Instance): Add check for actual which
11209 must have preelaborable initialization
11210 Use new // insertion for some continuation messages
11211 (Analyze_Formal_Object_Declaration): Change usage of Expression to
11212 Default_Expression. Add type retrieval when the declaration has an
11213 access definition. Update premature usage of incomplete type check.
11214 (Check_Access_Definition): New subsidiary routine. Check whether the
11215 current compilation version is Ada 05 and the supplied node has an
11217 (Instantiate object): Alphabetize local variables. Handle the creation
11218 of new renaming declarations with respect to the kind of definition
11219 used - either an access definition or a subtype mark. Guard against
11220 unnecessary error message in the context of anonymous access types after
11221 they have been resolved. Add check for required null exclusion in a
11222 formal object declaration.
11223 (Switch_View): A private subtype of a non-private type needs to be
11224 switched (the base type can have been switched without its private
11225 dependents because of the last branch of Check_Private_View.
11226 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
11228 (Instantiate_Type): Emit an error message whenever a class-wide type of
11229 a tagged incomplete type is used as a generic actual.
11230 (Find_Actual_Type): Extend routine to handle a component type in a child
11231 unit that is imported from a formal package in a parent.
11232 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
11233 agree on constrainedness, rather than checking against ultimate ancestor
11234 (Instantiate_Subprogram_Body): Create a cross-reference link to the
11235 generic body, for navigation purposes.
11237 2006-10-31 Robert Dewar <dewar@adacore.com>
11238 Thomas Quinot <quinot@adacore.com>
11240 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
11242 (New_Stream_Subprogram): When processing an attribute definition clause
11243 for a stream-oriented subprogram, record an entity node occurring at
11244 the point of clause to use for checking the visibility of the clause,
11245 as defined by 8.3(23) as amended by AI-195.
11246 (New_Stream_Subprogram): New procedure, factoring behaviour from both
11247 New_Stream_Function and New_Stream_Procedure.
11248 (New_Stream_Function, New_Stream_Procedure): Removed.
11249 (Analyze_Attribute_Definition_Clause, case Address): Check new
11250 Alignment_Check check
11252 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11253 Javier Miranda <miranda@adacore.com>
11254 Robert Dewar <dewar@adacore.com>
11256 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
11257 generate the same errors compiling under -gnatc.
11258 (Try_Object_Operation): If no candidate interpretation succeeds, but
11259 there is at least one primitive operation with the right name, report
11260 error in call rather than on a malformed selected component.
11261 (Analyze_Selected_Component): If the prefix is an incomplete type from
11262 a limited view, and the full view is available, use the full view to
11263 determine whether this is a prefixed call to a primitive operation.
11264 (Operator_Check): Verify that a candidate interpretation is a binary
11265 operation before checking the type of its second formal.
11266 (Analyze_Call): Add additional warnings for function call contexts not
11268 (Analyze_Allocator): Move the check for "initialization not allowed for
11269 limited types" after analyzing the expression. This is necessary,
11270 because OK_For_Limited_Init looks at the structure of the expression.
11271 Before analysis, we don't necessarily know what sort of expression it
11272 is. For example, we don't know whether F(X) is a function call or an
11273 indexed component; the former is legal in Ada 2005; the latter is not.
11274 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
11275 were missing. We also didn't handle qualified expressions. Now also
11276 allow function calls. Use new common routine OK_For_Limited_Init.
11277 (Analyze_Type_Conversion): Do not perform some legality checks in an
11278 instance, because the error message will be redundant or spurious.
11279 (Analyze_Overloaded_Selected_Component): Do not do style check when
11280 setting an entity, since we do not know it is the right entity yet.
11281 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
11282 (Analyze_Overloaded_Selected_Component): Same change
11283 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
11284 since regular incomplete subtypes are transformed into corresponding
11285 subtypes of their full views.
11286 (Complete_Object_Operation): Treat name of transformed subprogram call
11287 as coming from source, for browsing purposes.
11288 (Try_Primitive_Operation): If formal is an access parameter, compare
11289 with base type of object to determine whether it is a primitive
11291 (Operator_Check): If no interpretation of the operator matches, check
11292 whether a use clause on any candidate might make the operation legal.
11293 (Try_Class_Wide_Operation): Check whether the first parameter is an
11294 access type whose designated type is class-wide.
11296 2006-10-31 Robert Dewar <dewar@adacore.com>
11297 Ed Schonberg <schonberg@adacore.com>
11298 Gary Dismukes <dismukes@adacore.com>
11300 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
11301 warn on infinite loops.
11302 Add \\ to some continuation messages
11303 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
11304 (Process_Bounds): If the bounds are integer literals that result from
11305 constant-folding, and they carry a user-defined type, preserve that type
11306 rather than treating this as an integer range.
11307 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
11308 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
11309 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
11310 left hand side of assignment.
11311 (Analyze_Assignment): Add suport to manage assigments to the attribute
11312 priority of a protected object.
11313 (Check_Possible_Current_Value_Condition): Allow fully qualified names
11314 not just identifiers.
11315 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
11316 or AND THEN for possible tracking.
11317 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
11318 case of while loops so we can track values in the loop body.
11320 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11321 Hristian Kirtchev <kirtchev@adacore.com>
11322 Bob Duff <duff@adacore.com>
11324 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
11325 procedure cannot be a protected operation (it is a basic_declaration,
11326 not a subprogram_declaration).
11327 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
11328 Subp. Add logic for entry processing.
11329 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
11330 Determine whether an entry or subprogram of a protected or task type
11331 override an inherited primitive of an implemented interface.
11332 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
11333 Update the actual used in calls to Check_Overriding_Indicator.
11334 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
11335 generate the proper reference to the parent unit, for cross-reference.
11336 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
11338 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
11339 (Add_Extra_Formal): Revise procedure to allow passing in associated
11340 entity, scope, and name suffix, and handle setting of the new
11341 Extra_Formals field.
11342 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
11343 pass new parameters. Add support for adding the new extra access formal
11344 for functions whose calls are treated as build-in-place.
11345 (Analyze_A_Return_Statement): Correct casing in error message.
11346 Move Pop_Scope to after Analyze_Function_Return, because an extended
11347 return statement really is a full-fledged scope. Otherwise, visibility
11348 doesn't work right. Correct use of "\" for continuation messages.
11349 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
11350 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
11351 the node doesn't get properly marked as analyzed.
11352 (Analyze_Subprogram_Body): If subprogram is a function that returns
11353 an anonymous access type that denotes a task, build a Master Entity
11355 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
11356 proper usage of null exclusion in a result definition.
11357 (Process_Formals): Code cleanup and new error message.
11358 (Process_Formals): Detect incorrect application of null exclusion to
11360 (Conforming_Types): Handle conformance between [sub]types and itypes
11361 generated for entities that have null exclusions applied to them.
11362 (Maybe_Primitive_Operation): Add an additional type retrieval when the
11363 base type is an access subtype. This case arrises with null exclusions.
11364 (New_Overloaded_Entity): Do not remove the overriden entity from the
11365 homonym chain if it corresponds with an abstract interface primitive.
11366 (Process_Formals): Replace membership test agains Incomplete_Kind with a
11367 call to the synthesized predicate Is_Incomplete_Type.
11368 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
11370 (Analyze_Subprogram_Declaration): Check that abstract interface
11371 primitives are abstract or null.
11372 (Analyze_Subprogram_Specification): Remove previous check for abstract
11373 interfaces because it was not complete.
11374 (Has_Interface_Formals): Removed.
11376 2006-10-31 Ed Schonberg <schonberg@adacore.com>
11377 Javier Miranda <miranda@adacore.com>
11379 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
11380 of Analyze_Package_Body, to create Itype references for anonymous
11381 access types created in the package declaration, whose designated types
11382 may have only a limited view.
11383 (Analyze_Package_Specification): For the private part of a nested
11384 package, install private_with_clauses of enclosing compilation unit if
11385 we are in its visible part.
11386 (Declare_Inherited_Private_Subprograms): Complete barrier
11387 to ensure that the primitive operation has an alias to some parent
11388 primitive. This is now required because, after the changes done for the

12635 other basic tools. The full version that includes the Ada 2005 stuff

12637 not want to cause bootstrap problems with compilers not recognizing

12933 Thomas Quinot <quinot@adacore.com>
12935 * checks.adb (Build_Discriminant_Checks): If the expression being
12936 checks is an aggregate retrieve the values of its discriminants to
12937 generate the check, rather than creating a temporary and a reference

12940 (Install_Null_Excluding_Check): Ditto
12941 (Selected_Length_Checks): Build actual subtype for the original Ck_Node,

12959 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
12960 Remove 0-9 as debug flag character possibilities
12961 -d is now controlling the primary stack size when its value is a
12962 positive. Also add checks against invalid values, and support for kb,
12963 mb. Ditto for -D switch.
12965 2006-02-13 Robert Dewar <dewar@adacore.com>
12966 Serguei Rybin <rybin@adacore.com>
12968 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
12969 save/restore routines.
12970 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
12971 were not always properly handled previously.
12972 Since we are changing the tree format anyway, also get rid of the
12973 junk obsolete Immediate_Errors flag.
12974 (Tree_Read): Change the way of reading Tree_Version_String - now we
12975 read the version string from the tree even if its length is not the
12976 same as the length of the version string computed from Gnatvsn.
12977 (Search_Directory_Present): New Boolean flag for the compiler.
12978 Define Tree_Version_String as a dynamic string.

12993 Ed Schonberg <schonberg@adacore.com>
12995 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
12996 against errors in the source program: a private types for which the
12997 corresponding full type declaration is missing and pragma CPP_Virtual
12999 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
13000 (Is_Known_Null): New flag
13001 (Has_Pragma_Pure): New flag

13003 (Is_Limited_Type): A type whose ancestor is an interface is limited if
13004 explicitly declared limited.
13005 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
13006 entities. Only used for component marked Is_Tag. If present it stores

13008 whose ancestor has discriminants.
13010 * exp_ch2.adb: Update status of new Is_Known_Null flag
13012 * sem_ch7.adb: Maintain status of new Is_Known_Null flag

13026 (__gnat_handle_vms_condition): Adjust context before raise.
13027 (__gnat_install_handler): Restore the global vector setup for GCC
13028 versions before 3.4, as the frame based circtuitry is not available

13031 (__gl_default_stack_size): new variable.
13033 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13035 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
13036 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
13037 does not exist in the Ada RM.
13038 (Compatible_Int_Bounds): Determine whether two integer range bounds
13039 are of equal length and have the same start and end values.
13040 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
13041 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
13042 aggregate when it is part of an object declaration.
13043 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
13044 constrains discriminants of its parent, add explicitly the discriminant
13045 constraints of the ancestor by retrieving them from the
13046 stored_constraint of the parent.
13048 2006-02-13 Robert Dewar <dewar@adacore.com>
13050 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
13051 attribute Mechanism_Code is applied to renamed subprogram, modify
13052 prefix to point to base subprogram.
13053 Max/Min attributes now violate Restriction No_Implicit_Conditionals
13055 * sinfo.ads: Document that Mechanism_Code cannot be applied to
13056 renamed subprograms so that the front-end must replace the prefix
13059 2006-02-13 Javier Miranda <miranda@adacore.com>
13060 Gary Dismukes <dismukes@adacore.com>
13062 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
13063 availability of RE_Interface_Tag.
13064 (Build_Initialization_Call): Fix wrong access to the discriminant value.
13065 (Freeze_Record_Type): Do not generate the tables associated with
13066 timed and conditional dispatching calls through synchronized
13067 interfaces if compiling under No_Dispatching_Calls restriction.
13068 When compiling for Ada 2005, for a nonabstract
13069 type with a null extension, call Make_Controlling_Function_Wrappers
13070 and insert the wrapper function declarations and bodies (the latter
13071 being appended as freeze actions).
13072 (Predefined_Primitive_Bodies): Do not generate the bodies of the
13073 predefined primitives associated with timed and conditional
13074 dispatching calls through synchronized interfaces if we are
13075 compiling under No_Dispatching_Calls.
13076 (Build_Init_Procedure): Use RTE_Available to check if a run-time
13077 service is available before generating a call.
13078 (Make_Controlling_Function_Wrappers): New procedure.
13079 (Expand_N_Full_Type_Declaration): Create a class-wide master for
13080 access-to-limited-interfaces because they can be used to reference
13081 tasks that implement such limited interface.
13082 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
13083 procedure spec and body of the Offset_To_Top function that is generated
13084 when the parent of a type with discriminants has secondary dispatch
13086 (Init_Secondary_Tags): Handle the case in which the parent of the type
13087 containing secondary dispatch tables has discriminants to generate the
13088 correct arguments to call Set_Offset_To_Top.
13089 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
13091 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
13092 Add Wide_[Wide_]Expanded_Name.
13093 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
13094 the same functionality of Get_Prim_Op_Address but applied to predefined
13095 primitive operations because the pointers to the predefined primitives
13096 are now saved in a separate table.
13097 (Parent_Size): Modified to get access to the separate table of primitive
13098 operations or the parent type.
13099 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
13100 functionality of Set_Prim_Op_Address but applied to predefined primitive
13102 (Set_Signature): New subprogram used to store the signature of a DT.
13103 (Displace): If the Offset_To_Top value is not static then call the
13104 function generated by the expander to get such value; otherwise use
13105 the value stored in the table of interfaces.
13106 (Offset_To_Top): The type of the actual has been changed to Address to
13107 give the correct support to tagged types with discriminants. In this
13108 case this value is stored just immediately after the tag field.
13109 (Set_Offset_To_Top): Two new formals have been added to indicate if the
13110 offset_to_top value is static and hence pass this value to the run-time
13111 to store it in the table of interfaces, or else if this value is dynamic
13112 and then pass to the run-time the address of a function that is
13113 generated by the expander to provide this value for each object of the
13116 * rtsfind.ads (Default_Prin_Op_Count): Removed.
13117 (Default_Prim_Op_Count): New entity

13123 Ed Schonberg <schonberg@adacore.com>
13125 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
13126 Make_Adjust_Call done for a newly-allocated object.
13128 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
13129 in a subprogram are wrapped in a cleanup block, indicate that the
13130 subprogram contains an inner block with an exception handler.
13131 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
13132 Adjust call is for a newly-allocated object. In that case we must not
13133 assume that the finalization list chain pointers are correct (since they
13134 come from a bit-for-bit copy of the original object's pointers) so if
13135 the attach level would otherwise be zero (no change), we set it to 4
13136 instead to cause the pointers to be reset to null.
13138 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
13139 reset chain pointers to null.
13141 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13143 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
13144 string, and the context requires a loop for the assignment (e.g.
13145 because the left-hand side is packed), generate a unique name for the
13146 temporary that holds the string, to prevent spurious name clashes.
13148 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13149 Javier Miranda <miranda@adacore.com>
13150 Robert Dewar <dewar@adacore.com>
13151 Gary Dismukes <dismukes@adacore.com>
13153 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
13154 return unconstrained arrays.
13156 (Expand_Call): An indirect call through an access parameter of a
13157 protected operation is not a protected call.
13158 Add circuit to raise CE in Ada 2005 mode following call
13159 to Raise_Exception.
13160 (Register_DT_Entry): Do nothing if
13161 the run-time does not give support to abstract interfaces.
13162 (Freeze_Subprogram): In case of dispatching operations, do not generate
13163 code to register the operation in the dispatch table if the source
13164 is compiled with No_Dispatching_Calls.
13165 (Register_Predefined_DT_Entry): Generate code that calls the new
13166 run-time subprogram Set_Predefined_Prim_Op_Address instead of
13167 Set_Prim_Op_Address.
13169 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
13170 on array assignments if the right-hand side is a function call that has
13171 been inlined. Check is performed on the assignment in the block.
13172 (Process_Bounds): If bounds and range are overloaded, apply preference
13173 rule for root operations to disambiguate, and diagnose true ambiguity.
13174 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
13175 a tag-indeterminate right-hand side even when Expander_Active is True.
13176 Needed to ensure that dispatching calls to T'Input are allowed and
13177 get the tag of the target class-wide object.
13179 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
13180 an inherited primitive operation that already overrides several
13181 abstract interface primitives. For transitivity, the new entity must
13182 also override all the abstract interface primitives covered by the
13183 inherited overriden primitive.
13184 Emit warning if new entity differs from homograph in same scope only in
13185 that one has an access parameter and the other one has a parameter of
13186 a general access type with the same designated type, at the same
13187 position in the signature.
13188 (Make_Inequality_Operator): Use source locations of parameters and
13189 subtype marks from corresponding equality operator when creating the
13190 tree structure for the implicit declaration of "/=". This does not
13191 change anything in behaviour except that the decoration of the
13192 components of the subtree created for "/=" allows ASIS to get the
13193 string images of the corresponding identifiers.
13194 (Analyze_Return_Statement): Remove '!' in warning message.
13195 (Check_Statement_Sequence): Likewise.
13196 (Analyze_Subprogram_Body): For an access parameter whose designated type
13197 is an incomplete type imported through a limited_with clause, use the
13198 type of the corresponding formal in the body.
13199 (Check_Returns): Implicit return in No_Return procedure now raises
13200 Program_Error with a compile time warning, instead of beging illegal.
13201 (Has_Single_Return): Function returning unconstrained type cannot be
13202 inlined if expression in unique return statement is not an identifier.
13203 (Build_Body_To_Inline): It is possible to inline a function call that
13204 returns an unconstrained type if all return statements in the function
13205 return the same local variable. Subsidiary procedure Has_Single_Return
13206 verifies that the body conforms to this restriction.
13208 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
13209 same type, and one of them is of an anonymous access type, convert
13210 the other operand to it, so that this is a valid binary operation for
13212 (Resolve_Type_Conversion): Handle subtypes of protected types and
13213 task types when accessing to the corresponding record type.
13214 (Resolve_Allocator): Add '\' in 2-line warning message.
13215 Remove '!' in warning message.
13216 (Resolve_Call): Add '\' in 2-line warning message.
13217 (Valid_Conversion): Likewise.
13218 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
13219 resulting type may be an access type with an implicit dereference.
13220 Obtain the proper component from the designated type.
13221 (Make_Call_Into_Operator): Handle properly a call to predefined equality
13222 given by an expanded name with prefix Standard, when the operands are
13223 of an anonymous access type.
13224 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
13225 Explicit_Dereference and Resolve_Selected_Component, to verify that the
13226 prefix of the expression is not of an incomplete type. Allows full
13227 diagnoses of all semantic errors.
13228 (Resolve_Actuals): If the actual is an allocator whose directly
13229 designated type is a class-wide interface we build an anonymous
13230 access type to use it as the type of the allocator. Later, when
13231 the subprogram call is expanded, if the interface has a secondary
13232 dispatch table the expander will add a type conversion to force
13233 the displacement of the pointer.
13234 (Resolve_Call): If a function that returns an unconstrained type is
13235 marked Inlined_Always and inlined, the call will be inlined and does
13236 not require the creation of a transient scope.
13237 (Check_Direct_Boolean_Op): Removed
13238 (Resolve_Comparison_Op): Remove call to above
13239 (Resolve_Equality_Op): Remove call to above
13240 (Resolve_Logical_Op): Inline above, since this is only call.
13241 (Valid_Conversion): Handle properly conversions between arrays of
13242 convertible anonymous access types.
13245 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
13246 the literal in an unchecked conversion, because GCC 4.x needs a static
13247 value for a string bound.
13249 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13250 Hristian Kirtchev <kirtchev@adacore.com>
13252 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
13253 components of the corresponding record, take into account component
13254 definitions that are access definitions.
13255 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
13256 procedure is not considered a dispatching call and will be expanded
13259 2006-02-13 Javier Miranda <miranda@adacore.com>
13261 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
13262 controlling argument of the dispatching call is an abstract interface
13263 class-wide type then we use it directly.
13264 Check No_Dispatching_Calls restriction.
13265 (Default_Prim_Op_Position): Remove the code that looks for the last
13266 entity in the list of aliased subprograms. This code was wrong in
13268 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
13269 when the source is compiled with the No_Dispatching_Calls restriction.
13270 (Init_Predefined_Interface_Primitives): No need to inherit primitives
13271 if we are compiling with restriction No_Dispatching_Calls.
13272 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
13273 subprograms if we are compiling under No_Dispatching_Calls restriction.
13274 (Make_DT): Generate a dispatch table with a single dummy entry if
13275 we are compiling with the No_Dispatching_Calls restriction. In
13276 addition, in this case we don't generate code that calls to the
13277 following run-time subprograms: Set_Type_Kind, Inherit_DT.
13278 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
13279 of this subprogram if compiling with the No_Dispatching_Calls
13281 (Expand_Type_Conversion): Instead of using the actual parameter,
13282 the argument passed as parameter to the conversion function was
13283 erroneously referenced by the expander.
13284 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
13285 Set_Predefined_Primitive_Op_Address and Set_Signature.
13286 (Expand_Dispatching_Call): Generate call to
13287 Get_Predefined_Prim_Op_Address for predefined primitives.
13288 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
13289 predefined primitives.
13290 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
13291 primitives we reserve one dummy entry to ensure that the tag does not
13292 point to some memory that is associated with some other object. In
13293 addition, remove all the old code that generated the assignments
13294 associated with the signature of the dispatch table and replace them
13295 by a call to the new subprogram Set_Signature.
13296 (Set_All_DT_Position): Change the algorithm because now we have a
13297 separate dispatch table associated with predefined primitive operations.
13298 (Expand_Interface_Conversion): In case of non-static offset_to_top
13299 add explicit dereference to get access to the object after the call
13300 to displace the pointer to the object.
13301 (Expand_Interface_Thunk): Modify the generation of the actual used
13302 in the calls to the run-time function Offset_To_Top to fulfil its
13304 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.

13308 * exp_dist.adb (Copy_Specification): For access parameters, copy
13309 Null_Exclusion flag, which will have been set for stream subprograms
13312 2006-02-13 Pascal Obry <obry@adacore.com>
13314 * expect.c (__gnat_expect_portable_execvp): New implementation. The
13315 previous implementation was using the C runtime spawnve routine but
13316 the corresponding wait was using directly the Win32 API. This was
13317 causing some times a lock when waiting for an event using
13318 WaitForSingleObject in __gnat_waitpid. This new implementation uses
13319 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
13320 API fixes this problem.
13322 2006-02-13 Robert Dewar <dewar@adacore.com>
13324 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

13343 searching for the predefined equality operator, verify that operands
13344 have the same type.
13345 (Is_Predefined_Dispatching_Operation): Remove the code that looks
13346 for the last entity in the list of aliased subprograms. This code
13347 was wrong in case of renamings.
13348 (Set_Renamed_Subprogram): New procedure
13349 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
13350 Exp_Type constant computed when entering this subprogram.
13351 (Known_Null): New function
13352 (OK_To_Do_Constant_Replacement): New function
13353 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
13354 (Side_Effect_Free): An attribute reference 'Input is not free of
13355 side effect, unlike other attributes that are functions. (from code
13357 (Remove_Side_Effects): Expressions that involve packed arrays or records
13358 are copied at the point of reference, and therefore must be marked as
13359 renamings of objects.
13360 (Is_Predefined_Dispatching_Operation): Return false if the operation is
13361 not a dispatching operation.
13364 (Remove_Side_Effects): Lift enclosing type conversion nodes for
13365 elementary types in all cases.

13370 task types when accessing to the corresponding record type.
13371 Remove '!' in warning message.
13373 2006-02-13 Olivier Hainque <hainque@adacore.com>
13375 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
13376 to avoid useless and space inefficient overalignments on targets where
13377 Max_Alignment is larger than 16.
13379 2006-02-13 Pascal Obry <obry@adacore.com>
13381 * g-catiio.adb (Sec_Number): New type used to compute the number of
13382 seconds since 1-1-1970.
13383 (Image) [Natural]: The parameter was an Integer, as we can't deal with
13384 negative numbers (years, months...) it is better to have a Natural here.
13386 (Image) [Number]: Change parameter from Long_Integer to Number.
13387 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
13388 overflow for dates past year 2038.
13390 2006-02-13 Matthew Heaney <heaney@adacore.com>
13392 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
13395 2006-02-13 Arnaud Charlet <charlet@adacore.com>
13397 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
13399 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
13400 finalization can occur normally.
13402 2006-02-13 Vincent Celier <celier@adacore.com>
13404 * gnatcmd.adb (Rules_Switches): New table
13405 (Add_To_Rules_Switches): New procedure
13406 (GNATCmd): For command CHECK, put all options following "-rules" in the
13407 Rules_Switches table. Append these -rules switches after the -cargs
13410 2006-02-13 Robert Dewar <dewar@adacore.com>
13412 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
13413 These two cases were generating incorrect output, and if this unit
13414 was built with checks on, generated a discriminant mismatch constraint
13417 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13418 Robert Dewar <dewar@adacore.com>
13420 * lib-xref.adb (Get_Type_Reference): For a private type whose full
13421 view is an array type, indicate the component type as well, for
13422 navigation purposes.
13423 (Generate_Reference): Don't consider array ref on LHS to be a case
13424 of violating pragma Unreferenced.
13425 Do not give Ada 2005 warning except on real reference.
13427 2006-02-13 Vincent Celier <celier@adacore.com>
13429 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
13430 main source, add switch -mdebug-main=_ada_ so that the executable can
13431 be debugged by the standard VMS debugger.
13432 (Gnatmake): Set No_Main_Subprogram to True when there is no main
13433 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
13434 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
13435 of the last source, as the binding and linking phases are never
13437 Set all executable obsolete when rebuilding a library.
13439 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
13442 2006-02-13 Javier Miranda <miranda@adacore.com>
13445 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
13446 code to improve the error message reported when the program has
13447 declarations of abstract interface types and it is not compiled with
13448 the -gnat05 switch.
13449 (P_Access_Definition): Reorganize the code to improve the error
13450 message reported when the new Ada 2005 syntax for anonymous
13451 access types is used and the program is not compiled with the

13474 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
13475 unknown, use the location of the project to report the error.
13476 (When_No_Sources): New global variable
13477 (Report_No_Ada_Sources): New procedure
13478 (Check): New parameter When_No_Sources. Set value of global variable

13488 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
13489 Call Recursive_Check with parameter When_No_Sources.
13490 (Recursive_Check): New parameter When_No_Sources. Call itself and
13491 Prj.Nmsc.Check with parameter When_No_Sources.
13492 (Process): New parameter When_No_Sources. Call Check with parameter
13494 (Copy_Package_Declarations): New procedure to copy renamed parameters

13504 When removing nodes (attributes Source_Dirs, Source_Files,
13505 Source_List_File and package Naming), save the comments and attach the
13506 saved comments to the newly created nodes.
13507 Do not add a with clause for the naming package if one already exists.

13523 No_Return procedure with procedure that is not No_Return
13524 (Check_Dispatching_Call): Suppress the check for an abstract operation
13525 when the original node of an actual is a tag-indeterminate attribute
13526 call, since the attribute, which must be 'Input, can never be abstract.
13527 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
13528 call to the Input attribute (even when rewritten).
13529 (Propagate_Tag): Augment comment to indicate the possibility of a call
13530 to an Input attribute.
13532 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
13533 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.

13542 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
13544 2006-02-13 Javier Miranda <miranda@adacore.com>
13546 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
13547 handles default-initialized components to keep separate the management
13548 of this feature but also avoid the unrequired resolution and
13549 expansion of components that do not have partially initialized
13551 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
13552 (Check_Bounds): Likewise.
13553 (Check_Length): Likewise.
13555 2006-02-13 Javier Miranda <miranda@adacore.com>
13556 Ed Schonberg <schonberg@adacore.com>
13558 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
13559 abstract interface type call analyze_and_resolve to expand the type
13560 conversion into the corresponding displacement of the
13561 reference to the base of the object.
13562 (Eval_Attribute, case Width): For systems where IEEE extended precision
13563 is supported, the maximum exponent occupies 4 decimal digits.
13564 (Accessibility_Message): Add '\' in 2-line warning message.
13565 (Resolve_Attribute): Likewise.
13566 (case Attribute_Access): Significantly revise checks
13567 for illegal access-to-subprogram Access attributes to properly enforce
13568 the rules of 3.10.2(32/2).
13569 Diagnose use of current instance with an illegal attribute.
13571 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
13573 (Enclosing_Generic_Unit): New function to return a node's innermost
13574 enclosing generic declaration node.
13575 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
13576 (Type_Access_Level): The accessibility level of anonymous acccess types
13577 associated with discriminants is that of the current instance of the
13578 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
13579 (Compile_Time_Constraint_Error): Handle case of conditional expression.
13580 (Kill_Current_Values_For_Entity): New function
13581 (Enter_Name): Change formal type to Entity_Id

13587 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
13588 Analyze_Compilation_Unit.
13589 Detect and warn on redundant with clauses detected in a package spec
13590 and/or body when -gnatwr is used.

13592 (Install_Context_Items): Don't analyze config pragmas here
13593 (Install_Limited_Withed_Unit): Set limited entity of package in
13594 with_clause so that cross-reference information or warning messages on
13595 unused packages can be properly generated
13596 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
13597 has Error_Posted set. Prevent infinite loops in illegal programs.
13598 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
13599 to the point of the error test requiring the current unit to be private.
13600 This ensures that private with clauses are not exempted from the basic
13601 checking for being a descendant of the same library unit parent as a
13602 withed private descendant unit.
13603 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
13604 handle private with clauses properly, as well as to account for cases
13605 where the withed unit is a public descendant of a private ancestor
13606 (in which case the current unit must be a descendant of the private
13607 ancestor's parent). The spec comments were updated accordingly. Also,
13608 the old error message in this subprogram was replaced with error
13609 messages that mirror the errors tested and reported by
13610 Check_Private_Child_Unit.
13611 Parameter and variable names improved for readability.
13612 (Install_Limited_Context_Clauses): Remove test for a withed unit being
13613 private as the precondition for calling
13614 Check_Private_Limited_Withed_Unit since that subprogram has been
13615 revised to test public units as well as private units.

13627 with multiple levels of parametrization by formal packages.
13628 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
13629 to the corresponding derived type declaration for proper semantics.
13631 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
13632 (Check_Component): Enforce restriction on components of
13633 unchecked_unions: a component in a variant cannot contain tasks or
13635 (Unchecked_Union): Allow nested variants and multiple discriminants, to
13637 Add pragma Ada_2005 (synonym for Ada_05)
13638 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
13639 were not always properly handled previously.
13640 Document that pragma Propagate_Exceptions has no effect
13641 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
13642 (Set_Convention_From_Pragma): Check that if a convention is
13643 specified for a dispatching operation, then it must be
13644 consistent with the existing convention for the operation.
13645 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
13646 longer required to specify an vtable-ptr component in the record. For
13647 compatibility reasons we leave the support for the previous definition.
13648 (Analyze_Pragma, case No_Return): Allow multiple arguments
13650 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
13651 non-overrideen inherited operation with a controlling result as
13652 illegal only its implicit declaration comes from the derived type
13653 declaration of its result's type.
13654 (Check_Possible_Deferred_Completion): Relocate the object definition
13655 node of the subtype indication of a deferred constant completion rather
13656 than directly analyzing it. The analysis of the generated subtype will
13657 correctly decorate the GNAT tree.
13658 (Record_Type_Declaration): Check whether this is a declaration for a
13659 limited derived record before analyzing components.
13660 (Analyze_Component_Declaration): Diagnose record types not explicitly
13661 declared limited when a component has a limited type.
13662 (Build_Derived_Record_Type): Code reorganization to check if some of
13663 the inherited subprograms of a tagged type cover interface primitives.
13664 This check was missing in case of a full-type associated with a private
13666 (Constant_Redeclaration): Check that the subtypes of the partial and the
13667 full view of a constrained deferred constant statically match.
13668 (Mentions_T): A reference to the current type in an anonymous access
13669 component declaration must be an entity name.
13670 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
13671 class_wide type to refer to full type, not to the incomplete one.
13672 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
13673 available. Required to give support to the certified run-time.
13674 (Analyze_Component_Declaration): In case of anonymous access components
13675 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
13676 (Process_Discriminants): For an access discriminant, use the
13677 discriminant specification as the associated_node_for_itype, to
13678 simplify accessibility checks.
13680 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13681 Javier Miranda <miranda@adacore.com>
13683 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
13684 abstract interpretations on an operator, remove interpretations that
13685 yield Address or a type derived from it, if one of the operands is an
13687 (Try_Object_Operation.Try_Primitive_Operation,
13688 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
13689 location when creating the new reference to a primitive or class-wide
13690 operation as a part of rewriting a subprogram call.
13691 (Try_Primitive_Operations): If context requires a function, collect all
13692 interpretations after the first match, because there may be primitive
13693 operations of the same type with the same profile and different return
13694 types. From code reading.
13695 (Try_Primitive_Operation): Use the node kind to choose the proper
13696 operation when a function and a procedure have the same parameter
13698 (Complete_Object_Operation): If formal is an access parameter and prefix
13699 is an object, rewrite as an Access reference, to match signature of
13700 primitive operation.
13701 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
13702 by an expanded name with prefix Standard, when the operands are of an
13703 anonymous access type.
13704 (Remove_Abstract_Operations): If the operation is abstract because it is
13705 inherited by a user-defined type derived from Address, remove it as
13706 well from the set of candidate interpretations of an overloaded node.
13707 (Analyze_Membership_Op): Membership test not applicable to cpp-class
13710 2006-02-13 Bob Duff <duff@adacore.com>
13712 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
13713 redundant use clauses.
13714 In particular, if the scope of two use clauses overlaps, but one is not
13715 entirely included in the other, we should not warn. This can happen
13716 with nested packages.
13717 (Analyze_Subprogram_Renaming): Protect the compiler against previously
13718 reported errors. The bug was reported when the compiler was built
13719 with assertions enabled.
13720 (Find_Type): If the node is a 'Class reference and the prefix is a
13721 synchronized type without a corresponding record, return the type
13724 2006-02-13 Javier Miranda <miranda@adacore.com>
13726 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
13727 if this is the full-declaration associated with a private declaration
13728 that implement interfaces, then the private type declaration must be
13730 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
13731 as aliased. The use of the 'access attribute is not available for such
13732 object (for this purpose the object should be explicitly marked as
13733 aliased, but being an anonymous type this is not possible).
13735 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13736 Robert Dewar <dewar@adacore.com>
13738 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
13739 compilation unit is an elaboration scope.
13740 (Add_Task_Proc): Add '\' in 2-line warning message.

13743 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13744 Javier Miranda <miranda@adacore.com>
13746 * sem_type.adb (Write_Overloads): Improve display of candidate
13748 (Add_One_Interp): Do not add to the list of interpretations aliased
13749 entities corresponding with an abstract interface type that is an
13750 immediate ancestor of a tagged type; otherwise we have a dummy
13751 conflict between this entity and the aliased entity.
13752 (Disambiguate): The predefined equality on universal_access is not
13753 usable if there is a user-defined equality with the proper signature,
13754 declared in the same declarative part as the designated type.
13755 (Find_Unique_Type): The universal_access equality operator defined under
13756 AI-230 does not cover pool specific access types.
13757 (Covers): If one of the types is a generic actual subtype, check whether
13758 it matches the partial view of the other type.
13760 2006-02-13 Thomas Quinot <quinot@adacore.com>
13762 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
13763 line. This is necessary to allow In_Extended_Main_Unit to provide
13764 correct results for itypes while writing out expanded source.
13765 (Close_File): No need to update the source_index_table here since it's
13766 now done for each line.
13768 2006-02-13 Ed Schonberg <schonberg@adacore.com>
13769 Robert Dewar <dewar@adacore.com>
13771 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
13772 preserve the source unit where the itype is declared, and prevent a

13790 raise Constraint_Error.
13792 * s-vallli.adb (Scan_Long_Long_Integer): Call
13793 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
13794 do not scan leading blanks and sign twice.
13795 Integer'Value("- 5") and Integer'Value("-+5") now correctly
13796 raise Constraint_Error.
13798 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
13799 Scan_Long_Long_Unsigned): Split out most of the processing from
13800 Scan_Long_Long_Unsigned out into
13801 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
13802 This prevents scanning leading blanks and sign twice.
13803 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
13806 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
13807 out most of the processing from Scan_Unsigned out into
13808 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
13809 This prevents scanning leading blanks and sign twice.
13811 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
13812 use with Modular'Value attribute.
13813 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

14011 * a-taster.ads, a-taster.adb: New files.
14013 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
14014 link to the version that does nothing. This way the task termination
14015 routine is not executed twice for the environment task when finishing
14016 because of an unhandled exception.
14018 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
14019 handler because of an unhandled exception.
14021 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
14022 System.Tasking.Utilities instead of that in System.Tasking.Stages.

14025 finalization of the global list instead of Adafinal.
14027 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
14028 non-tasking version of the soft link for task termination. We do
14029 nothing since if we are using the non-tasking version it
14030 means that the task termination functionality is not used.
14031 (Null_Finalize_Global_List): Add this null version for the procedure
14032 in charge of finalizing the global list for controlled objects.
14033 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
14034 instead for handling run-time termination in a more flexible way.
14035 (Adafinal_NT): This new procedure will take care of finalizing the
14036 global list for controlled objects if needed, but no tasking
14039 * s-tarest.adb (Task_Lock): Do not try to lock again the
14040 Global_Task_Lock if we already own it. Otherwise, we get blocked in
14041 some run-time operations.
14042 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
14043 until all nested locks have been released.
14044 (Task_Wrapper): Call the fall-back task termination handler. It
14045 applies to all tasks but the environment task.
14046 (Finalize_Global_Tasks): Add the call for the task termination
14047 procedure for the environment task.
14048 (Task_Wrapper): suppress warnings around declaration of
14049 Secondary_Stack_Address.
14051 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
14052 moved to the Common_ATCB record.
14053 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
14054 Common_ATCB record.
14055 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
14056 Common_ATCB record.
14058 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
14059 Fall_Back_Handler, and Specific_Handler.
14061 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
14062 defined in Ada.Task_Termination, to avoid circular dependencies.
14063 (Termination_Handler): Redefine this type here, alredy defined in
14064 Ada.Task_Termination, for avoiding circular dependencies.
14065 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
14066 for storing task termination handlers. In addition,
14067 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
14068 Common_ATCB because it is used by both the regular and the restricted
14070 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
14071 Common_ATCB because it is used by both the regular and the restricted
14073 (Common_ATCB): Added a dynamic task analyzer field.
14075 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
14076 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
14077 (Task_Wrapper): Call the task termination handler. It applies to all
14078 tasks but the environment task.
14079 (Finalize_Global_Tasks): Call the task termination procedure for the
14080 environment task. The call to Finalize_Global_List is now performed
14081 using the soft links mechanism.
14082 (Task_Wrapper): added dynamic stack analysis.
14084 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
14085 potentially blocking operations has been moved from
14086 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
14087 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
14088 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
14089 this run-time check.
14091 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
14092 of task termination procedure.
14093 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
14094 link for the task termination procedure.
14096 * bindusg.adb: (Bindusg): Added documentation for -u option.

14109 * s-io.ads, s-io.adb (Standard_Error): new subprogram
14110 (Standart_Output): new subprogram
14111 (Set_Output): new subprogram
14112 (Put): now uses the value of Current_Out to know if the output has to be
14113 send to stderr or stdout.
14115 * s-stausa.ads: Complete implementation.
14117 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
14119 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
14120 list of Ada 05 files.
14121 (GNAT Library Units): Add AltiVec files.

14130 file_name is empty.
14132 2005-12-09 Javier Miranda <miranda@adacore.com>
14133 Hristian Kirtchev <kirtchev@adacore.com>
14135 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
14136 to the specification because the frontend generates code that uses this
14138 (Set_Interface_Table): Add missing assertion.
14139 Update documentation describing the run-time structure.
14140 (Displace): New subprogram that displaces the pointer to the object
14141 to reference one of its secondary dispatch tables.
14142 (IW_Membership): Modified to use the new table of interfaces.
14143 (Inherit_TSD): Modified to use the new table of interfaces.
14144 (Register_Interface_Tag): Use the additional formal to fill the
14145 contents of the new table of interfaces.
14146 (Set_Interface_Table): New subprogram that stores in the TSD the
14147 pointer to the table of interfaces.
14148 (Set_Offset_To_Top): Use the additional formal to save copy of
14149 the offset value in the table of interfaces.
14150 Update structure of GNAT Primary and Secondary dispatch table diagram.
14151 Add comment section on GNAT dispatch table prologue.
14152 (Offset_To_Signature): Update the constant value of the Signature field.

14159 (Get_Tagged_Kind, Set_Tagged_Kind): New bodies.
14161 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
14162 in all the calls to Expand_Interface_Thunk. Instead of referencing the
14163 record component containing the tag of the secondary dispatch table we
14164 have to use the Offset_To_Top run-time function to get this information;
14165 otherwise if the pointer to the base of the object has been displace
14166 we get a wrong value if we use the 'position attribute.
14168 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
14169 all the calls to Expand_Interface_Thunk.
14170 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
14171 interfaces; hence the call to Set_Interface_Table was clearly wrong.
14172 (Collect_All_Interfaces): Modify the internal subprogram Collect to
14173 ensure that the interfaces implemented by the ancestors are placed
14174 at the header of the generated list.
14175 (Expand_Interface_Conversion): Handle the case in which the displacement
14176 associated with the interface conversion is not statically known. In
14177 this case we generate a call to the new run-time subprogram Displace.
14178 (Make_DT): Generate and fill the new table of interfaces.
14179 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
14180 Get_Tagged_Kind and Set_Tagged_Kind.
14181 (Tagged_Kind): New function that determines the tagged kind of a type
14182 with respect to limitedness and concurrency and returns a reference to
14184 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
14185 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
14186 primary dispatch table for a type.
14187 (Make_DT, Make_Secondary_DT): Set the tagged kind in the primary and
14188 secondary dispatch table respectively of a tagged type.
14190 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
14191 (Expand_Interface_Conversion): New subprogram to indicate if the
14192 displacement of the type conversion is statically known.
14193 (DT_Access_Action): Add values Get_Tagged_Kind and Set_Tagged_Kind.
14195 * rtsfind.ads (RE_Offset_To_Top): New entity
14196 (RTU_Id): Add Ada_Task_Termination to the list so that it is made
14197 accessible to users.
14198 (Re_Displace): New entity
14199 (RE_Interface_Data): New entity
14200 (RE_Set_Interface_Data): New_Entity
14201 (RE_Id, RE_Unit_Table): Add entry for RE_Get_Tagged_Kind,
14202 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
14203 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
14204 RE_TK_Tagged, RE_TK_Task.
14206 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
14207 Init_Secondary_Tags_Internal to allow its use with interface types and
14208 also to generate the code for the new additional actual required
14209 by Set_Offset_To_Top.
14210 (Build_Init_Statements): In case of components associated with abstract
14211 interface types there is no need to generate a call to its IP.
14212 (Freeze_Record_Type): Generate Select Specific Data tables only for
14214 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
14215 the bodies and specifications of the predefined primitive operations
14216 dealing with dispatching selects and abort, 'Callable, 'Terminated only
14217 for concurrent types.
14219 * exp_sel.ads, exp_sel.adb: New files.
14221 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
14222 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
14223 properly protected objects and attach handler in the case of the
14224 restricted profile.
14225 Move embeded package Select_Expansion_Utilities into a separate external
14227 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
14228 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
14229 (Build_K, Build_S_Assignment): New subprograms, part of the select
14230 expansion utilities.

14409 (Analyze_Component_Declaration): A limited component is
14410 legal within a protected type that implements an interface.
14411 (Collect_Interfaces): Do not add to the list the interfaces that
14412 are implemented by the ancestors.
14413 (Derived_Type_Declaration): If the parent of the full-view is an
14414 interface perform a transformation of the tree to ensure that it has
14415 the same parent than the partial-view. This simplifies the job of the
14416 expander in order to generate the correct object layout, and it is
14417 needed because the list of interfaces of the full-view can be given in
14419 (Process_Full_View): The parent of the full-view does not need to be
14420 a descendant of the parent of the partial view if both parents are
14422 (Analyze_Private_Extension_Declaration): If declaration has an explicit

14497 available user-specified stream attributes on limited parameters to
14498 also test the type directly rather than only its underlying type (for
14499 Ada 95) and, in the case of Ada 2005, to check that the user-specified
14500 attributes are visible at the point of the subprogram declaration.
14501 For Ada 2005, the error message is modified to indicate that the
14502 type's stream attributes must be visible (again, only for -gnat05).

14534 types use the corresponding record type. This was not needed before
14535 the implementation of Ada 2005 synchronized types because
14536 concurrent types were never tagged types in Ada 95.

14775 deal with different cases of static and dynamic elaboration checks (all
14776 checks does not count in the first case, but does in the second).

14782 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
14783 elementary types using the operator in standard. It is cleaner not to
14784 modify the programmers intent, especially in the case of floating-point.
14785 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
14786 it did not matter because we always rewrote a/=b to not(a=b).

14788 subtype is an unconstrained packed type, convert the expression to its
14789 actual constrained subtype.

14810 Allow optional = after -gnatm
14811 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
14812 longer sets Elaboration_Checks.
14813 Code to set warning mode moved to Sem_Warn
14814 so that it can be shared by pragma processing.
14816 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
14819 * s-taprop-solaris.adb:
14820 Change some <= to =, to avoid new warning

14828 * exp_vfpt.adb: Handle /= case
14829 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
14830 so that we do not get duplicate scaling for fixed point conversions.

14834 2005-11-14 Matthew Gingell <gingell@adacore.com>
14836 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
14837 Increase default priority on Lynx from 15 to 17, and meet the Ada
14838 requirement that Default_Priority be ((Priority'First +
14839 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

14941 we are not defining the type.
14942 <E_Record_Type>: Likewise.
14943 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
14944 to get advantage of the new maybe_stabilize_reference interface, to
14945 ensure that what we reference is indeed stabilized instead of relying
14946 on assumptions on what the stabilizer does.
14947 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
14948 type imported through a limited_with clause, use its non-limited view.
14949 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
14951 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
14952 of #if sections + explicit comparisons of convention identifiers.

14954 before early-returning for certain types when code generation is
14956 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

14958 that we are not defining.
14959 (elaborate_expression_1): Do not create constants when creating
14960 variables needed by the debug info: the dwarf2 writer considers that
14961 CONST_DECLs is used only to represent enumeration constants, and emits
14963 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
14964 object with an address clause into an indirect reference, drop the
14965 initializing expression.
14967 (STACK_CHECK_BUILTIN): Delete.
14968 (STACK_CHECK_PROBE_INTERVAL): Likewise.

14976 if there is an actual subtype provided by the front-end, use that
14977 subtype to build an actual type with bounds template.
14978 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
14979 is provided by the front-end, use that subtype to compute the size of
14980 the deallocated object.

14982 check for a potential violation of a No_Elaboration_Code restriction.

14987 maybe_stabilize, for common uses without restriction on lvalues and
14988 without need to check for the success indication.
14989 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
14990 pass false instead of 0 as the FORCE argument which is a bool.
14991 (Identifier_to_gnu): Remove checks ensuring that an renamed object
14992 attached to a renaming pointer has been properly stabilized, as no such
14993 object is attached otherwise.
14994 (call_to_gnu): Invoke create_var_decl to create the temporary when the
14995 function uses the "target pointer" return mechanism.
14996 Reinstate conversion of the actual to the type of the formal
14997 parameter before any other specific treatment based on the passing
14998 mechanism. This turns out to be necessary in order for PLACEHOLDER
14999 substitution to work properly when the latter type is unconstrained.

15003 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

15007 * utils2.c (gnat_build_constructor): Only sort the fields for possible
15008 static output of record constructor if all the components are constant.
15009 (gnat_build_constructor): For a record type, sort the list of field
15010 initializers in increasing bit position order.
15011 Factor common code to build a storage type for an unconstrained object
15012 from a fat or thin pointer type and a constrained object type.
15013 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
15014 types variants, and process special cases of VIEW_CONVERT expressions
15015 as their NOP_EXPR counterpart to ensure we get to the
15016 CORRESPONDING_VARs associated with CONST_DECls.
15017 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
15018 on the right-hand side.

15025 extracting the object if converting to a type variant.
15026 (create_var_decl): When a variable has an initializer requiring code
15027 generation and we are at the top level, check for a potential violation
15028 of a No_Elaboration_Code restriction.
15029 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
15030 SIZE and SIZE_UNIT which we need for later back-annotations.

15032 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
15033 is an unchecked union.
15034 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
15035 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
15036 main variant, just replace the VIEW_CONVERT_EXPR.

15209 Hristian Kirtchev <kirtchev@adacore.com>
15211 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
15212 and related): For a prefix that is an explicit dereference of an
15213 access to unconstrained packed array type, annotate the dereference
15214 with an actual subtype so GIGI can make a correct size computation.
15215 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
15216 'Unrestricted_Access, if the designated type is an interface we
15217 add a type conversion to force the displacement of the pointer
15218 to the secondary dispatch table.
15219 Use Universal_Real instead of Long_Long_Float when we need a high
15220 precision float type for the generated code (prevents gratuitous
15221 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
15222 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
15223 'Terminated for task interface class-wide objects. Generate a call to
15224 the predefined dispatching routine used to retrieve the _task_id from

15247 necessary for the statements within the block: analyze it with checks
15249 (Expand_N_If_Statement): When killing a dead then-branch in an
15250 if-statement that has elsif_parts, recompute the Current_Value node
15251 for any entity whose value is known from the condition of the first
15253 (Expand_N_Return_Statement): When returning a mutable record, convert
15254 the return value into its actual subtype in order to help the backend
15255 to return the actual size instead of the maximum. This is another
15256 aftermath of not returning mutable records on the sec-stack anymore.
15258 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
15259 handling of error msg for suspicious reverse range iteration.
15260 (Check_Possible_Current_Value_Condition): Move declaration from body to

15271 * expect.c (__gnat_kill) [Win32]: Fix implementation, the pid returned
15272 by spawnve is a process handle, no need to convert. Add a parameter
15273 close to control wether the process handle must be closed.
15274 (__gnat_waitpid): Fix implementation, the pid returned by spawnve is
15275 a process handle, not need to convert.
15276 (__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.
15278 * g-expect.adb: (Kill): Document the new close parameter.

15305 attribute of the N_Free_Statement.
15306 Generate itype for classwide designated object in both cases of
15307 user-specified storage pool: specific and class-wide, not only in the
15309 Raise CE when trying to set a not null access type object to null.
15310 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
15311 an explicit loop, because freeze nodes make its position variable.

15396 longer need a separate version of this package for VMS.
15398 2005-11-14 Ed Schonberg <schonberg@adacore.com>
15400 * lib-xref.adb (Generate_Definition, Generate_Reference): Treat the

15489 rhs of an assignment even if the type is unconstrained, when the
15490 context is non-expanding.
15491 In an inlined body, if the context type is private,
15492 resolve with its full view, which must be a composite type.

15504 (Implicit_With_On_Parent): Do add duplicate with_clause on parent when
15505 compiling body of child unit.
15506 Use new class N_Subprogram_Instantiation

15530 parent scopes of a scope being removed prior to inlining an instance
15532 (Analyze_Package_Instantiation): Do not perform front-end inlining when

15534 unit, to prevent scope stack errors.
15535 (Save_References): If the node is an aggregate that is an actual in a
15536 call, rewrite as a qualified expression to preserve some type
15537 information, to resolve possible ambiguities in the instance.
15538 (Instance_Parent_Unit): New global variable to record the ultimate
15539 parent unit associated with a generic child unit instance (associated

15547 not already set. Replace test of Is_Child_Unit with test of parent's
15548 scope against package Standard. Add comments and a ??? comment.
15549 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
15550 on a child instance parent to test that the parent equals

15567 (Build_Private_Derived_Type): The entity of the created full view of the
15568 derived type does not come from source. If after installing the private
15569 declarations of the parent scope the parent is still private, use its
15570 full view to construct the full declaration of the derived type.
15571 (Build_Derived_Record_Type): Relax the condition that controls the
15572 execution of the check that verifies that the partial view and
15573 the full view agree in the set of implemented interfaces. In

15581 view is a transitive derivation of the ancestor of the partial view.
15582 (Process_Full_View): Rename local subprogram Find_Interface_In_
15583 Descendant to Find_Ancestor_Interface to leave the code more clear.
15584 Remove wrong code that avoids the generation of an error message
15585 when the immediate ancestor of the partial view is an interface.
15586 In addition some minor reorganization of the code has been done to
15587 leave it more clear.
15588 (Analyze_Type_Declaration): If type has previous incomplete tagged
15589 partial view, inherit properly its primitive operations.
15590 (Collect_Interfaces): Make public, for analysis of formal

15602 and derived protected types, the parent may be an interface that must
15603 be included in the interface list.
15604 (Access_Definition): If the designated type is an interface that may
15605 contain tasks, create Master_Id for it before analyzing the expression
15606 of the declaration, which may be an allocator.
15607 (Record_Type_Declaration): Set properly the interface kind, for use
15608 in allocators, the creation of master id's for task interfaces, etc.

15617 subprogram declaration.
15618 Change name Is_Package to Is_Package_Or_Generic_Package
15619 (Process_Formals): A non null qualifier on a non null named access
15620 type is not an error, and is a warning only if Redundant_Constructs

15624 Ed Schonberg <schonberg@adacore.com>
15626 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
15627 nested within Analyze_Package_Specification to install the private
15628 declarations and use clauses within each of the parent units of a
15629 package instance of a generic child package.
15630 (Analyze_Package_Specification): When entering a private part of a
15631 package associated with a generic instance or formal package, the
15632 private declarations of the parent must be installed (by calling new
15633 procedure Install_Parent_Private_Declarations).
15634 Change name Is_Package to Is_Package_Or_Generic_Package
15635 (Preserve_Full_Attributes): For a synchronized type, the corresponding

15641 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
15642 not try to rewrite a renamed stream attribute, because the operations
15643 on the type may not have been generated.
15644 Handle properly a renaming_as_body generated for a stream operation
15645 whose default is abstract because the object type itself is abstract.
15646 (Find_Type): If the type is incomplete and appears as the prefix of a
15647 'Class reference, it is tagged, and its list of primitive operations
15648 must be initialized properly.
15649 (Chain_Use_Clauses): When chaining the use clauses that appear in the
15650 private declaration of a parent unit, prior to compiling the private
15651 part of a child unit, find on the scope stack the proper parent entity
15652 on which to link the use clause.
15653 (Note_Redundant_Use): Emit a warning when a redundant use clause is
15655 (Analyze_Object_Renaming): An attribute reference is not a legal object

15673 a procedure call is used as a select statement trigger and is not an
15674 entry renaming or a primitive of a limited interface.
15675 (Valid_Conversion): If the operand has a single interpretation do not
15676 remove address operations.
15677 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise

16416 required; otherwise performs a type conversion that will be
16417 expanded in the code that returns the value of the displaced actual.
16418 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
16419 conversions that have no effect in the generated code because no
16420 displacement is required. Code cleanup; use local variables to
16421 avoid repeated calls to the subprogram directly_designated_type().

16723 position set is provided, we compute one in order to reduce the maximum
16724 length of the keys. This computation first selects a character
16725 position between 1 and the minimum length of the keys in order to
16726 avoid reducing one of the keys to an empty string.
16727 (Initialize, Compute): When the ratio V to K is too low, the algorithm
16728 does not converge. The initialization procedure now comes with a
16729 maximum number of iterations such that when exceeded, an exception is
16730 raised in Compute. The user can initialize this ratio to another value

16792 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
16793 Result_Definition for cases of N_Access_Function_Definition and
16794 N_Function_Specification.
16795 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
16797 2005-09-01 Vincent Celier <celier@adacore.com>
16799 * lib-writ.adb: Update Copyright notice
16800 (Write_With_Lines): On platforms where file names are case-insensitive,
16801 record the file names in lower case.
16802 (Write_ALI): For D lines, on platforms where file names are
16803 case-insensitive, record the file names in lower case.
16805 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16806 Emmanuel Briot <briot@adacore.com>
16808 * lib-xref.adb (Output_Overridden_Op): Display information on
16809 overridden operation.
16811 * lib-xref.ads: Add documentation on overridden operations.
16813 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
16816 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
16817 overriding entity information.
16819 2005-09-01 Vincent Celier <celier@adacore.com>
16821 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
16822 including those that are inherited.
16824 2005-09-01 Robert Dewar <dewar@adacore.com>
16826 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
16828 * par-prag.adb: Implement new pragma Debug_Policy
16830 * sem_prag.adb Implement new pragma Debug_Policy
16831 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
16832 Component_Size attribute specification. Give warning for ignored pragma
16835 * snames.h, snames.ads, snames.adb: Introduce entries in
16836 Preset_Names for Name_Disp_Asynchronous_Select,
16837 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
16838 Name_Disp_Timed_Select.
16839 New pragma Debug_Policy
16841 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
16843 Switch -gnata also sets Debug_Pragmas_Enabled
16845 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
16846 handle an explicit -gnata when compiling predefined files.
16848 2005-09-01 Vincent Celier <celier@adacore.com>
16850 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
16851 directories of projects that have no Ada sources.
16853 2005-09-01 Robert Dewar <dewar@adacore.com>
16855 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
16856 (makes a difference for wide characters)
16858 * widechar.adb, widechar.ads:
16859 Add Wide_Char_Byte_Count feature to count chars vs bytes
16861 2005-09-01 Thomas Quinot <quinot@adacore.com>
16862 Ed Schonberg <schonberg@adacore.com>
16863 Robert Dewar <dewar@adacore.com>
16865 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
16866 'Address attribute reference with an overloaded prefix, use the
16867 location of the prefix (not the location of the attribute reference) as
16868 the error location.
16869 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
16870 a function renaming thereof, is a valid prefix for 'Size (where it is
16871 intepreted as a function call).
16872 (Statically_Denotes_Entity): New predicate to determine whether the
16873 prefix of an array attribute can be considered static.
16876 (Eval_Attr): Fix failure to evaluate Component_Size for
16877 unconstrained arrays (resulted in wrong value in packed case, since
16878 back end cannot handle this case)
16880 2005-09-01 Robert Dewar <dewar@adacore.com>
16882 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
16883 error msgs for most common cases.
16884 Use new errout insertion char < (conditional warning)
16886 2005-09-01 Javier Miranda <miranda@adacore.com>
16887 Ed Schonberg <schonberg@adacore.com>
16889 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
16890 become local to the whole package.
16891 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
16892 the package was already analyzed the new algorithm "replaces" the
16893 real entities by the shadow ones. This is required to ensure that
16894 the order of these entities in the homonym chains does not change;
16895 otherwise we can have undefined references at linking time because
16896 in case of conflicts the external name of the entities will have
16897 a suffix that depends on the order of the entities in the chain.
16898 (Remove_Limited_With_Clause): Complementary code that completes the
16899 new algorithm and replaces the shadow entities by the real ones.
16900 (Install_Limited_Withed_Unit): When unchaining entities before the
16901 installation of the shadow entities, only regular entities of the
16902 public part must be taken into account. This is required to
16903 keep this routine in synch with the work done by Remove_Limited_
16905 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
16906 even if unit is analyzed, because the analysis of the unit is
16907 idempotent in any case, and the limited view of the unit may have to
16908 be installed for proper visibility.
16909 (Expand_Limited_With_Clause): Even if the unit in the implicit
16910 with_clause has been analyzed already, a limited view of the package
16911 must be built for the current context, if it does not exist yet.
16913 2005-09-01 Ed Schonberg <schonberg@adacore.com>
16914 Javier Miranda <miranda@adacore.com>
16915 Gary Dismukes <dismukes@adacore.com>
16917 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
16918 defining entity for the instance body, make a new defining identifier
16919 rather than copying the entity of the spec, to prevent accidental
16920 sharing of the entity list.
16921 (Check_Private_View): When exchanging views of private types, build the
16922 list of exchanged views as a stack, to ensure that on exit the exchanges
16923 are undone in the proper order.
16924 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
16925 Restore the compilation environment in case of instantiation_error.
16926 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
16927 for an anonymous access result.
16928 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
16929 (Formal_Entity): Handle properly the case of a formal package that
16930 denotes a generic package renaming.
16932 2005-09-01 Thomas Quinot <quinot@adacore.com>
16934 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
16935 clause if the array aggregate is surrounded by parentheses.
16937 2005-09-01 Cyrille Comar <comar@adacore.com>
16938 Gary Dismukes <dismukes@adacore.com>
16939 Ed Schonberg <schonberg@adacore.com>
16940 Javier Miranda <miranda@adacore.com>
16942 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
16944 to check if a type is Constrained in cases related to code generation
16945 (rather than semantic checking) since otherwise we do not generate
16946 similar code for mutable private types depending if their
16947 discriminants are visible or not.
16948 (Check_Abstract_Overriding): Do not complain about failure to override
16949 the primitive operations used in dispatching selects since they will
16950 always be overriden at the freeze point of the type.
16951 (Access_Definition): Separate out handling for resetting the scope
16952 of an anonymous access function result type. Retrieve the scope
16953 of the associated function rather than using Current_Scope, which
16954 does not have a consistent value (depends on whether we're in the
16955 middle of analyzing formal parameters). Add ??? comment about
16956 finding a cleaner way to handle the special cases of scope setting.
16957 (Process_Incomplete_Dependents): A protected operation is never a
16958 dispatching operation (only its wrapper may be).
16959 (Build_Derived_Record_Type): In case of tagged private types that
16960 implement interfaces add derivation of predefined primitive
16962 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
16963 by two parameters that are used in case of derivation from abstract
16964 interface types: No_Predefined_Prims is used to avoid the derivation
16965 of predefined primitives from the interface, and Predefined
16966 Prims_Only is used to complete the derivation predefined primitives
16967 in case of private tagged types implementing interfaces.
16968 Fix typo in comments
16969 (Find_Interface_In_Descendant): Protect the frontend against
16970 wrong code with large circularity chains.
16971 (Is_Private_Overriding): Add support for entities overriding interface
16972 subprograms. The test failed because Entities associated with overriden
16973 interface subprograms are always marked as hidden (and used to build
16974 the secondary dispatch table); in this case the overriden entity is
16975 available through the field abstract_interface_alias (cf. override_
16976 dispatching_operation)
16977 (Access_Definition): Set the scope of the type to Current_Scope for the
16978 case of a function with an anonymous access result type.
16979 (Access_Subprogram_Declaration): Handle creation of the type entity for
16980 an access-to-function type with an anonymous access result.
16981 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
16982 in handling for N_Access_Function_Definition.
16983 (Analyze_Subtype_Declaration): Modify the text of error message.
16984 (Derived_Type_Declaration): Modify the text of error message.
16985 (Process_Subtype): Modify the text of error message plus cleanup
16986 of one redundant error message.
16987 (Analyze_Component_Declaration): Code cleanup.
16988 (Analyze_Object_Declaration): Code cleanup.
16989 (Analyze_Subtype_Declaration): Propagate the null-exclusion
16990 attribute in case of access types. Code cleanup.
16991 (Array_Type_Declaration): Code cleanup.
16992 (Process_Discriminants): Create the new null-excluding itype
16993 if required. Code cleanup.
16994 (Process_Subtype): Create the new null-excluding itype if
16995 required. Code cleanup.
16996 (Build_Derived_Record_Type): Code cleanup to avoid calling
16997 twice the subprogram derive_subprograms in case of private
16998 types that implement interfaces. In this particular case the
16999 subprogram Complete_Subprograms_Derivation already does the
17000 job associated with the second call.
17002 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
17003 conversion to the full view when generating an operation for a
17004 discriminant whose type may currently be private.
17006 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17007 Javier Miranda <miranda@adacore.com>
17009 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
17010 V (Obj.F), the rewriting does not involve the indexed component, but
17011 only the selected component itself.
17012 Do not apply the transformation if the analyzed node is an actual of a
17013 call to another subprogram.
17014 (Complete_Object_Operation): Retain the entity of the
17015 dispatching operation in the selector of the rewritten node. The
17016 entity will be used in the expansion of dispatching selects.
17017 (Analyze_One_Call): Improve location of the error message associated
17019 (Analyze_Selected_Component): No need to resolve prefix when it is a
17020 function call, resolution is done when parent node is resolved, as
17022 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
17023 when attempting to resolve a call transformed from its object notation.
17024 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
17025 of the argument list for each interpretation of the operation.
17026 (Try_Object_Operation): The designated type of an access parameter may
17027 be an incomplete type obtained through a limited_with clause, in which
17028 case the primitive operations of the type are retrieved from its full
17030 (Analyze_Call): If this is an indirect call, and the return type of the
17031 access_to_subprogram is incomplete, use its full view if available.
17033 2005-09-01 Javier Miranda <miranda@adacore.com>
17034 Gary Dismukes <dismukes@adacore.com>
17036 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
17037 access types the null-exclusion and access-to-constant attributes must
17039 (Analyze_Return_Statement): When the result type is an anonymous access
17040 type, apply a conversion of the return expression to the access type
17041 to ensure that appropriate accessibility checks are performed.
17042 (Analyze_Return_Type): For the case of an anonymous access result type,
17043 generate the Itype and set Is_Local_Anonymous_Access on the type.
17044 Add ??? placeholder for check to disallow returning a limited object
17045 in Ada 2005 unless it's an aggregate or a result of a function call.
17046 Change calls from Subtype_Mark to Result_Definition.
17047 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
17048 Result_Definition in call to Make_Function_Specification.
17049 (Build_Body_To_Inline): Change Set_Subtype_Mark to
17050 Set_Result_Definition.
17051 (Make_Inequality_Operator): Change formal Subtype_Mark to
17052 Result_Definition in call to Make_Function_Specification.
17053 (Process_Formals): Create the new null-excluding itype if required.
17054 (New_Overloaded_Entity): For an entity overriding an interface primitive
17055 check if the entity also covers other abstract subprograms in the same
17056 scope. This is required to handle the general case, that is, overriding
17057 other interface primitives and overriding abstract subprograms inherited
17058 from some abstract ancestor type.
17059 (New_Overloaded_Entity): For an overriding entity that comes from
17060 source, note the operation that it overrides.
17061 (Check_Conformance, Type_Conformant): Addition of one new formal
17062 to skip controlling formals in the analysis. This is used to
17063 handle overloading of abstract interfaces.
17064 (Base_Types_Match): Add missing case for types imported from
17065 limited-with clauses
17066 (New_Overloaded_Entity): Add barrier to protect the use of
17067 the "alias" attribute.
17069 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17071 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
17072 verify that the procedure and the entry are mode conformant.
17073 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
17074 as a different operator, which is often a cut-and-paste error.
17076 2005-09-01 Javier Miranda <miranda@adacore.com>
17077 Ed Schonberg <schonberg@adacore.com>
17079 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
17080 used in controlling parameters exclude null because it is necessary to
17081 read the tag to dispatch, and null has no tag.
17082 (Override_Dispatching_Operation): If the previous operation is inherited
17083 from an interface, it becomes hidden and does not participate in later
17086 2005-09-01 Javier Miranda <miranda@adacore.com>
17087 Ed Schonberg <schonberg@adacore.com>
17088 Gary Dismukes <dismukes@adacore.com>
17090 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
17091 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
17092 the expander will generate the corresponding run-time check to evaluate
17094 (Resolve_Call): Check for legal type of procedure name or prefix that
17095 appears as a trigger in a triggering alternative.
17096 (Valid_Conversion): If expression is ambiguous and the context involves
17097 an extension of System, remove System.Address interpretations.
17098 (Resolve_Qualified_Expression): Reject the case of a specific-type
17099 qualification applied to a class-wide argument. Enhance comment
17100 to explain checking of Original_Node.
17101 (Resolve_Type_Conversion): The location of the error message was not
17102 general enough to handle the general case and hence it has been removed.
17103 In addition, this patch improves the text of the message.
17104 (Resolve_Type_Conversion): Add missing support for access to interface
17106 (Resolve_Type_Conversion): If the target is a class-wide interface type,
17107 do not expand if the expression is the actual in a call, because proper
17108 expansion will take place when the call itself is expanded.
17109 (Resolve_Allocator): If the context is an unchecked conversion, the
17110 allocator inherits its storage pool, if any, from the target type of
17113 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17114 Javier Miranda <miranda@adacore.com>
17116 * sem_type.adb (Add_One_Interp): If a candidate operation is an
17117 inherited interface operation that has an implementation, use the
17118 implementation to avoid spurious ambiguities.
17119 (Interface_Present_In_Ancestor): In case of concurrent types we can't
17120 use the Corresponding_Record_Typ attribute to look for the interface
17121 because it is set by the expander (and hence it is not always
17122 available). For this reason we traverse the list of interfaces
17123 (available in the parent of the concurrent type).
17124 (Interface_Present_In_Ancestor): Handle entities from the limited view
17126 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17128 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
17129 from the list of required components.
17130 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
17131 primitive procedure of a limited interface with a controlling first
17133 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
17135 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
17136 capture if it is generated in the second operand of a short-circuit
17138 Do not capture values for variables with address clauses.
17139 (Is_Object_Reference): Treat a function call as an object reference only
17140 if its type is not Standard_Void_Type.
17142 2005-09-01 Ed Schonberg <schonberg@adacore.com>
17144 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
17145 to a variable that is statically known to be constant.
17147 2005-09-01 Geert Bosch <bosch@adacore.com>
17148 Robert Dewar <dewar@adacore.com>

17157 Document that bounds of result of Base_Name match the input index
17159 Add documentation on environment variable syntax for Expand_Path
17161 * gnat_ugn.texi: Update documentation to include mention of -m switches
17162 Document new treatment of wide characters in max line length
17164 Remove -gnatL/-gnatZ switches, no longer used.
17165 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
17168 * gnat_rm.texi: Add doc for two argument form of pragma
17169 Float_Representation.
17170 Add documentation for pragma No_Strict_Aliasing
17171 Add note that explicit component clause overrides pragma Pack.
17172 Add documentation of pragma Debug_Policy

17767 * s-mastop-irix.adb (Pop_Frame): Revert shorcuts avoiding calls to
17768 exc_unwind, now that we are generating proper .debug_frame output for
17771 * tracebak.c: Remove the mips-irix section, as we are now using the
17772 s-mastop based unwinder again.
17773 Under SPARC/Solaris, take into account the stack bias to compute the
17774 frame offset. The stack bias is 0 for the V8 ABI and 2047 for the V9

17927 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
17928 longer protected objects. They have been replaced by lower-level
17929 suspension objects made up by a mutex and a condition variable (or
17930 their equivalent given a particular OS) plus some internal data to
17931 reflect the state of the suspension object.
17932 (Initialize, Finalize): Add this initialization procedure for
17933 Suspension_Object, which is a controlled type.
17934 (Finalize): Add the finalization procedure for Suspension_Object,
17935 which is a controlled type.
17937 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
17938 Ada.Synchronous_Task_Control because there is no longer a need for a
17939 VxWorks specific version of this package. Target dependencies
17940 has been moved to System.Task_Primitives.Operations.
17942 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
17944 (InitializeCriticalSection, EnterCriticalSection,
17945 LeaveCriticalSection, DeleteCriticalSection): Replace the type
17946 pCriticalSection by an anonymous access type so that we avoid problems
17947 of accessibility to local objects.

17953 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
17954 set the environment task mask here.
17955 (Current_State): Add this function that returns the state of the
17957 (Set_False): Add this procedure that sets the state of the suspension
17959 (Set_True): Add this procedure that sets the state of the suspension
17960 object to True, releasing the task that was suspended, if any.
17961 (Suspend_Until_True): Add this procedure that blocks the calling task
17962 until the state of the object is True. Program_Error is raised if
17963 another task is already waiting on that suspension object.
17964 (Initialize): Add this procedure for initializing the suspension
17965 object. It initializes the mutex and the condition variable which are
17966 used for synchronization and queuing, and it sets the internal state
17968 (Finalize): Add this procedure for finalizing the suspension object,
17969 destroying the mutex and the condition variable.

17974 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
17975 which provides a low-level abstraction (using operating system
17976 primitives) for Ada.Synchronous_Task_Control.
17977 This object is made up by a mutex (for ensuring mutual exclusion), a
17978 condition variable (for queuing threads until the condition is
17979 signaled), a Boolean (State) indicating whether the object is open,
17980 and a Boolean (Waiting) reflecting whether there is a task already
17981 suspended on this object.

17993 * s-inmaop.ads (Setup_Interrupt_Mask): New procedure
17995 * s-interr.adb: Add explicit call to Setup_Interrupt_Mask now that
17996 this is no longer done in the body of s-taprop
17997 (Server_Task): Explicitely test for Pending_Action in case
17998 System.Parameters.No_Abort is True.
18000 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
18001 is no longer done in the body of s-taprop

18174 * exp_ch5.adb (Expand_N_Return_Statement): When a function's result
18175 type is a class-wide type, emit a run-time check that the accessibility

18246 type derivation of private tagged types implementing interfaces.
18247 In this case some interface primitives may have been overriden

18313 (Expand_Call, Freeze_Subprogram): Modified to give support to abstract
18315 (Expand_Inlined_Call): Mark temporary generated for the return value as

18337 * i-cpp.ads, i-cpp.adb:
18338 This package has been left available for compatibility with previous
18339 versions of the frontend. As part of the new layout this is now a

18383 (Analyze_Subprogram_Body): Undo the previous work.
18384 (Analyze_Procedure_Call): If the call has the form Object.Op, the
18385 analysis of the prefix ends up analyzing the call itself, after which

18393 access to subprograms must be recursive.
18394 (Is_Unchecked_Conversion): Improve the test that recognizes
18395 instantiations of Unchecked_Conversion, and allows them in bodies that
18396 are to be inlined by the front-end. When the body comes from an
18397 instantiation, a reference to Unchecked_Conversion will be an
18398 Expanded_Name, even though the body has not been analyzed yet.

18419 object or component (that is, when Is_Local_Anonymous_Access is true).
18420 Prevent the special checks for conversions of access discriminants in
18421 the case where the discriminant belongs to a nonlimited type, since
18422 such discriminants have their accessibility level defined in the same
18423 way as a normal component of an anonymous access type.
18424 (Resolve_Allocator): When an allocator's designated type is a class-wide
18425 type, check that the accessibility level of type given in the
18426 allocator's expression or subtype indication is not statically deeper
18427 than the level of the allocator's access type.

18441 weakened in Ada 2005.
18442 Call to obsolescent subprogram is now considered to be a violation of
18443 pragma Restrictions (No_Obsolescent_Features).
18444 (Check_Direct_Boolean_Operator): If the boolean operation has been
18445 constant-folded, there is nothing to check.
18446 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
18447 check on possible violation of restriction No_Direct_Boolean_Operators
18448 until after expansion of operands, to prevent spurious errors when

18871 (Get_Type_Reference): For a subtype that is the renaming of an actual in
18872 an instantiation, use the first_subtype to ensure that we don't generate

18904 different contents.
18905 (__gnat_adjust_context_for_raise) i386-linux: First version of this
18906 function for this target. Adjust PC by one in the machine context. This
18907 adjustment was previously done in the MD_FALLBACK_FRAME_STATE_FOR, but

19405 (check dos line terminator).
19406 (Check_Line_Max_Length): New procedure, split off from the existing
19407 Check_Line_Terminator routine. Separating this out allows -gnatyf to
19408 be properly recognized.
19410 * styleg.adb: Add ??? comment for line terminator reference
19412 * scng.adb (Check_End_Of_Line): Fix bug of -gnatyf being ignored
19413 (Check_End_Of_Line): Add -gnatyd handling (check dos line terminators)
19415 * styleg.ads (Check_Line_Terminator): Add check for new switch -gnatyd
19416 (check dos line terminator).
19417 (Check_Line_Max_Length): New procedure, split off from the existing

19453 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
19454 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
19455 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
19456 analyzed if expansion is disabled (which could otherwise cause spurious
19457 error messages if expansion has been disabled due to previous
19458 (unrelated) errors).
19460 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
19461 is disabled, the entity denoted by the argument is the access type
19462 itself, not an underlying record type, so there is no need to go back
19463 to the Corresponding_Remote_Type.
19465 2005-03-29 Gary Dismukes <dismukes@adacore.com>
19466 Robert Dewar <dewar@adacore.com>
19468 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
19469 expand a call to an instance of
19470 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
19471 Constructor actual of the instance. A class-wide membership
19472 check is also generated, to ensure that the tag passed to the instance
19473 denotes a type in the class.
19474 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
19475 of Name_Generic_Dispatching_Constructor.
19477 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
19478 05 unit for AI-260-02).
19480 * a-tgdico.ads: New file.
19482 * impunit.adb (Non_Imp_File_Names_05): Add entry "a-tgdico" for new

19490 character type cases.
19491 (Analyze_Subprogram_Renaming): Add special handling for
19492 the case of renaming of stream attributes when the renaming denotes a
19493 generic formal subprogram association for an abstract formal subprogram.
19494 Check that the attribute is a primitive stream attribute (and not
19495 a class-wide stream attribute) and then rewrite the attribute name
19496 as the name of the appropriate compiler-generated stream primitive.
19498 2005-03-29 Robert Dewar <dewar@adacore.com>
19500 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

19507 * freeze.adb (Freeze_Record_Type): If the type of the component is an
19508 itype whose parent is controlled and not yet frozen, do not create a
19509 freeze node for the itype if expansion is disabled.
19511 2005-03-29 Vincent Celier <celier@adacore.com>
19513 * make.adb (Gnatmake): Don't fail if the main project file is declared
19514 as having no Ada sources. Do not display message "no sources to
19515 compile" in quiet output.
19517 2005-03-29 Doug Rupp <rupp@adacore.com>
19519 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as
19522 2005-03-29 Robert Dewar <dewar@adacore.com>
19524 * par-ch12.adb (P_Generic): Give better msg for illegal private generic

19530 missing TYPE Improve the error message generated when compiling a
19531 limited interface in Ada83 or Ada95 mode.
19533 2005-03-29 Robert Dewar <dewar@adacore.com>
19535 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
19536 rather than proceed ahead using a junk attribute name.
19538 2005-03-29 Vincent Celier <celier@adacore.com>
19540 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
19542 * prj-part.adb (Parse_Single_Project): Set the location of a project
19543 on its defining identifier, rather than on the reserved word "project".
19545 * prj-proc.adb (Expression): Adapt to the fact that default of external
19546 references may be string expressions, not always literal strings.
19547 (Recursive_Process): Set Display_Name equal to Name
19548 when Location is No_Location, that is when there is no actual file.
19549 Get the Display_Name of the project from the source, when it is not a
19551 (Process): Use the Display_Name in error messages
19553 * prj-strt.adb (External_Reference): Allow default to be string
19554 expressions, not only literal strings.
19556 2005-03-29 Vincent Celier <celier@adacore.com>

19563 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
19564 forbid conversion of a local access-to-subprogram type to a remote one.
19566 * sem_util.adb (Wrong_Type): For a record type that is the expanded
19567 equivalent type for a remote access-to-subprogram type, go back to the
19568 original RAS entity when displaying an error message, so the casing is
19569 the original source casing.

19573 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
19576 2005-03-29 Ed Schonberg <schonberg@adacore.com>
19578 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
19579 subtype if code is being pre-analyzed, to prevent un-expanded
19580 references to protected formals, among others.
19581 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
19582 interpretation that can be a call, include the result of the call as a
19583 possible interpretation of the dereference.
19585 * sem_ch5.adb (Process_Bounds): Determine type of range by
19586 pre-analyzing a copy of the original range, and then analyze the range
19587 with the expected type.
19589 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
19590 with an overloaded prefix where not all interpretations yield an
19591 access to subprogram, do not rewrite node as a call.
19592 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
19593 the node as a call once the context identifies the interpretation of
19594 the prefix whose call yields the context type.
19595 (Valid_Conversion): For the case of a conversion between
19596 local access-to-subprogram types, check subtype conformance using
19597 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
19598 detailed error message.

19602 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
19603 indicator, indicate that the formal can never be null.
19604 (Process_Formals): If a formal has a non_null indicator, insert the
19605 resulting subtype immediately before the enclosing subprogram decl,
19606 and not at the beginning of the corresponding declarative part, to
19607 prevent access before elaboration (Ada2005).

19716 to install the visible declarations of the enclosing scope of a
19717 record_type_with_private to establish the proper visibility before
19718 freezing the entity and related subprograms.

19730 explanatory error message (including the name of the missing attribute).
19731 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
19732 subprogram determines whether a default implementation exists for a
19733 given stream attribute.
19734 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
19735 Determine whether to generate a default implementation for each stream
19736 attribute separately, as this depends on the specific attribute.
19738 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
19739 limited extension where a stream attribute is missing for a limited
19740 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

19779 the default for the tree, not the global default naming.
19781 * prj-proc.adb (Recursive_Process): No need to put the default naming
19782 in the project data, it's already there.

20274 Task_Body_Procedure has been moved to the corresponding task type
20275 or task subtype entity to leave a field free to store the list
20276 of interfaces implemented by a task (for AI-345)

20341 expression to the type of the object when the object is constant.
20342 Reverse defer_debug_incomplete_list before traversing it, so that trees
20343 are processed in the order at which they were added to the list. This
20344 order is important when using the stabs debug format.

20370 (update_pointer_to): Fix pasto.
20371 (convert) <UNION_TYPE>: Accept slight type variations when
20372 converting to an unchecked union type.
20374 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
20375 replace the N_Freeze_Entity with a null statement.
20377 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
20378 within a constrained subcomponent of an enclosing record, place the
20379 freeze nodes in the scope stack entry for the enclosing record.
20380 (Undelay_Type): New Subprogram.
20381 (Set_Small_Size): Pass T, the type to modify; all callers changed.
20382 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
20383 within records; allow them to have freeze nodes if their base types
20386 * exp_util.adb (Remove_Side_Effects): Properly test for
20387 Expansion_Delayed and handle case when it's inside an
20388 N_Qualified_Expression.
20390 * sem_ch3.adb (Derived_Type_Declaration): New predicate
20391 Comes_From_Generic, to recognize accurately that the parent type in a
20392 derived type declaration can be traced back to a formal type, because
20393 it is one or is derived from one, or because its completion is derived
20395 (Constrain_Component_Type): If component comes from source and has no
20396 explicit constraint, no need to constrain in in a subtype of the
20398 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
20399 Minor change to propagate Is_Ada_2005 flag
20401 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
20402 Expansion_Delayed is False.
20403 (assoc_to_constructor): Ignore fields that have a
20404 Corresponding_Discriminant.
20405 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
20406 function returns "by target", dereference the target pointer using the
20407 type of the actual return value.
20408 <all>: Be prepared for a null gnu_result.
20409 (processed_inline_subprograms): Check flag_really_no_inline
20410 instead of flag_no_inline.
20411 (set_second_error_entity): Remove unused function.
20412 (gnat_to_gnu, case N_Selected_Component): Call
20413 gnat_to_gnu_field_decl.

20416 2005-03-15 Robert Dewar <dewar@adacore.com>
20417 Ed Schonberg <schonberg@adacore.com>
20418 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
20420 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
20421 Must_Be_Byte_Aligned for cases where we do not need to use a
20422 System.Pack_nn unit.
20424 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
20426 Needed now that we do some processing for IN parameters as well. This
20427 may well fix some unrelated errors.
20428 (Expand_Call): Handle case of unaligned objects (in particular those
20429 that come from packed arrays).
20430 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
20431 renamed entity is an inherited operation, re-expand the call using the
20432 original operation, which is the one to call.
20433 Detect attempt to inline parameterless recursive subprogram.
20434 (Represented_As_Scalar): Fix to work properly with private types
20435 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
20436 accurate estimate. Yields True in far fewer cases than before,
20437 improving the quality of code that depends on this test.
20439 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
20440 over both visible and private declarations to remove them from tree,
20441 and mark subprograms declared in package as eliminated, to prevent
20442 spurious use in subsequent compilation of generic units in the context.
20444 * exp_util.ads: Minor cleanup in variable names
20446 * sem_eval.ads, sem_eval.adb: Minor reformatting
20447 (Compile_Time_Known_Bounds): New function
20449 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20451 * exp_ch7.adb (Convert_View): Use base types of underlying types when
20452 determining whether an unchecked conversion is needed for the argument
20453 of an initialization call.
20455 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20457 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
20458 that appears in the instantiation rather than the internal subtype
20459 generated in the wrapper package, to avoid anomalies in gigi when the
20460 target is derived from a private type whose full view is an access type.
20462 2005-03-15 Robert Dewar <dewar@adacore.com>
20464 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
20466 Add documentation to replace the use of this flag
20467 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
20470 2005-03-15 Thomas Quinot <quinot@adacore.com>
20472 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
20473 here from exp_attr so it can be shared between exp_attr and exp_dist.
20474 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
20475 all TSS names, not a subset thereof, and the previous name introduced
20476 an unnecessarily confusion that a distinction might exist between
20477 "OK" TSS names and some "not OK" TSS names.
20479 2005-03-15 Doug Rupp <rupp@adacore.com>
20481 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
20484 2005-03-15 Pascal Obry <obry@adacore.com>
20485 Eric Botcazou <ebotcazou@adacore.com>
20489 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
20490 when IN_RTS. This is to work around a bootstrap path problem.
20492 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
20493 table and pass it to __gnat_install_SEH_handler().
20494 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
20496 * lang.opt: Fix specification of -fRTS=.
20498 2005-03-15 Doug Rupp <rupp@adacore.com>
20499 Bernard Banner <banner@adacore.com>
20500 Vincent Celier <celier@adacore.com>
20501 Arnaud Charlet <charlet@adacore.com>
20504 This change works fine when gnatlib is built from the gcc directory,
20505 but does not work when using the libada Makefile, since GCC_FOR_TARGET
20506 is not passed to ada/Makefile.in, so more work is needed by a
20507 Makefile/configure expert.
20509 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
20510 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
20511 Setup gnatlink switch -M for x86_64 linux, as it is already setup
20513 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
20514 Run ranlib on libgccprefix.a
20515 Define PREFIX_OBJS for Darwin, to build libgccprefix.
20516 (ADA_INCLUDE_SRCS): Split Ada packages.
20518 2005-03-15 Robert Dewar <dewar@adacore.com>
20520 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
20522 * impunit.adb: Add GNAT.UTF_32
20524 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
20526 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
20527 now uses GNAT.UTF_32).
20529 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
20530 capabilities for categorizing characters using Unicode categories
20532 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20534 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
20535 instantiation that has been rewritten as a package body, retrieve spec
20536 to generate proper name for implicit_with_clause.
20537 (Install_Parents): Recognize a parent that is an instantiation but has
20538 been rewritten as a package declaration during analysis.
20540 2005-03-15 Javier Miranda <miranda@adacore.com>
20541 Ed Schonberg <schonberg@adacore.com>
20543 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
20544 parameter reported some error we immediately return. This improves the
20545 behaviour of the frontend in case of errors.
20546 (Install_Parent, Remove_Parent): Introduce new flag
20547 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
20548 ancestor of a generic child unit, when the child is being instantiated.
20549 (Inline_Instance_Body): If we are compiling the private
20550 part or the body of a child unit, restore the proper visibility of the
20551 parents after compiling the instance body.
20553 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20554 Javier Miranda <miranda@adacore.com>
20557 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
20558 of a private type, in which case it is underlying_type that denotes
20559 the proper task. Also modified to use the new entity attribute
20560 that is directly available in the task type and task subtype entities
20561 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
20562 arrays when other dimensions than the first are constrained by
20563 discriminants of an enclosing record.
20564 (Insert_Explicit_Dereference): If the prefix is an indexed component or
20565 a combination of indexed and selected components, find ultimate entity
20566 and generate the appropriate reference for it, to suppress spurious
20568 (Note_Possible_Modification): If an entity name has no entity, return.
20569 (Is_Variable): A function call never denotes a variable.
20570 (Requires_Transient_Scope): For record types, recurse only on
20571 components, not on internal subtypes that may have been generated for
20572 constrained components.
20574 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20576 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
20577 Eliminated as candidates for resolution. Both efficient, and avoids
20578 anomalies with operators declared in deleted code.
20579 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
20580 expansion is disabled (as when compiling a generic) to prevent spurious
20581 warnings on prefixes of selected components.
20583 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20585 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
20586 attached to a list before checking whether it appears in the private
20587 declarations of the current package.
20588 (Make_Inequality_Operator): Insert declaration in proper declarative
20589 list rather than just setting the Parent field, so that
20590 Is_Private_Declaration can handle it properly.
20592 2005-03-15 Ed Schonberg <schonberg@adacore.com>
20594 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
20595 a renaming a body, check that the renamed subprogram in not intrinsic.
20596 (Find_Direct_Name): If several use_visible entities hide
20597 each other, and the context is a predefined file compiled through
20598 rtsfind, keep only the entity that comes from a predefined file.
20600 2005-03-15 Geert Bosch <bosch@adacore.com>
20602 * s-fatgen.adb (Valid): Extend special exceptions to account for long
20603 long float padding to also cover AMD64 and IA64.
20605 2005-03-15 Gary Dismukes <dismukes@adacore.com>
20607 * s-imgwch.adb: Add with and use of Interfaces.
20608 (Img_Wide_Character): Change type of Val to Unsigned_16.
20609 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
20611 2005-03-15 Matthew Gingell <gingell@adacore.com>

20656 Cyrille Comar <comar@adacore.com>
20657 Sergey Rybin <rybin@adacore.com>
20659 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
20660 too specific and long-winded to be appropriate for the GNAT User's
20662 Warn about use of GCC switches not documented in the GNAT User's Guide,
20663 as these may cause generated code to not conform to Ada semantics.
20664 Remove mention of -gdwarf-2 for sparc64, since this is now the default.

20793 This includes proper initialization with Normalize_Scalars.
20794 (Get_Simple_Init_Val): Major rewrite for initialize scalars and
20795 normalize scalars cases (particularly the latter) to do a better job
20796 of finding invalid representations.

20923 and Tok_Synchronized.
20925 * sem_res.adb (Resolve_Actuals): Change error messages to refer to
20926 "dispatching" rather than "primitive" operations, since dispatching
20927 calls are now allowed to abstract formal subprograms (which are not
20929 Char_Literal_Value field is now a Uint
20930 (Resolve_Slice): If the prefix is an access to an unconstrained array,
20931 compute the actual subtype of the designated object to impose the proper
20933 (Resolve_Selected_Component): Do not insert an access check if the
20934 prefix is an access type: such a node is expanded into an explicit
20935 dereference, on which the access check is performed anyway. Removes
20936 expensive duplicate checks.
20937 (Resolve_Call): Use new flag Is_Obsolescent and field
20938 Obsolescent_Warning so that pragma Obsolescent works on library
20940 Add support for wide wide character type
20941 (Resolve_Allocator): Replace the error message on wrong null-exclusion
20942 value by a warning message.
20943 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
20944 as fixed-point, and one of the operands is non-static and universal, it
20945 can only be an illegal exponentiation operation, in which case there is
20946 no real value to retrieve.
20948 * exp_strm.adb: Add support for wide wide character type
20949 (Build_Elementary_Input_Call): Compute the size of the stream element by

20989 (Unit_Declaration_Node): Ditto.
20990 (Is_Variable_Prefix): For the case of an indexed component whose prefix
20991 has a packed array type, the prefix has been rewritten into a type

20997 * stringt.ads, stringt.adb: Handle full UTF-32 range.
20998 Remove ["0A"] from comment, since it can look like a line terminator.
20999 Currently we don't permit this, but this is under discussion by the
21000 ARG, and it is easy enough to use a different example.
21002 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
21003 handling UTF-32 encoding for wide wide character.

21057 associated with a tagged primitive subprogram.
21058 (Expand_Dispatching_Call): Add support for a controlling actual that is

21062 describing the new layout.
21063 (Dispatch_Table): The expander computes the actual array size, allocates
21064 the Dispatch_Table record accordingly, and generates code that displaces
21065 the base of the record after the Typeinfo_Ptr component. The access to
21066 these components is done by means of local functions.
21067 (Offset_To_Top): New function.
21068 (Typeinfo_Ptr): New function.
21069 (Get_TSD): Modified to access the new position of the TSD.

21080 N_Formal_Subtype_Declaration (which is now a subtype).
21081 (Analyze_Formal_Subprogram): Add handling for
21082 N_Formal_Abstract_Subprogram, marking the formal as abstract and
21083 dispatching, setting the controlling status of the formal parameters
21084 and result, and issuing an error if there is no controlling type for
21085 the formal subprogram.
21086 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
21087 which is an unclean use of that field, we set the new field
21088 Corresponding_Formal_Spec to make the formal subprogram available to

21090 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
21091 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
21092 Constrained, so that it is is does not statically match its anonymous

21096 abstract formal subprograms in error check for functions returning
21097 abstract types. Set scope of new designator for

21100 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
21101 subprogram only if inner one comes from source.
21102 (Analyze_Function_Call): If the call is given in object notation, the
21103 analysis of the name rewrites the node and analyzes it with the proper
21104 argument list. After analyzing the name, if the call has been rewritten
21105 and the result type is set, no further analysis is needed.
21106 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
21107 mark in function specification, in a context where the formals are
21108 visible and hide outer homographs.
21110 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
21111 as the tagged type for the cases of abstract formal subprograms and
21112 renamings of those. Clean up spec comments.
21113 (Check_Dispatching_Context): Add error message to indicate "abstract
21114 procedure", covering the case of a call to a formal abstract procedure
21115 that has statically tagged operands.
21116 (Check_Dispatching_Call): Check for the case of an actual given by
21117 a tag-indeterminate function call whose type is an ancestor of the
21118 containing call's associated tagged type. This situation can occur
21119 for inherited primitives with function defaults. In this case we
21120 use the tagged type's tag directly as the controlling argument for
21122 (Expand_Call): Name change on call to Expand_Dispatch_Call.
21124 * sprint.adb (Sprint_Node_Actual): Split
21125 N_Formal_Subprogram_Declaration into two alternatives for the new

21202 on the field if Pragma Component_Alignment (Storage_Unit).
21203 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
21204 side-effects as if it were a constant; also make SAVE_EXPR to protect

21222 2005-02-09 Ed Schonberg <schonberg@adacore.com>
21224 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
21225 component of an array of arrays in an assignment context, and the
21226 aggregate has component associations that require sliding on
21227 assignment, force reanalysis of the aggregate to generate a temporary
21228 before the assignment.
21229 (Must_Slide): Make global to the package, for use in Gen_Assign.
21231 2005-02-09 Ed Schonberg <schonberg@adacore.com>
21233 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
21234 unchecked union with no inferable discriminants, return a
21235 Raise_Program_Error node, rather than inserting it at the point the
21237 (Expand_Record_Equality, Component_Equality): Handle properly the case
21238 where some subcomponent is an unchecked union whose generated equality
21239 code raises program error.

21247 Arnaud Charlet <charlet@adacore.com>
21249 * init.c (__gnat_initialize): Add a new parameter eh which contains the
21250 address of the exception registration. The Win32 version of this
21251 routine calls __gnat_install_SEH_handler() to initialize the SEH
21252 (Structured Exception Handling) handler.
21253 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
21254 SEH (Structured Exception Handling) now.
21255 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
21256 (__gnat_initialize for ppc-vxworks): Adjust comments and the
21257 preprocessor condition protecting the call to the extra eh setup
21258 subprogram, which is only available for the ppc target.
21259 (__gnat_clear_exception_count): replaced reference to
21260 variable taskIdCurrent by call to taskIdSelf(), cleaner.
21262 * seh_init.c: New file.
21264 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
21265 (GNATBIND_OBJS): Idem.
21267 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
21268 routine takes a new parameter (a pointer to the exception registration
21269 for the SEH (Structured Exception Handling) support.
21271 * raise.h: (__gnat_install_SEH_handler): New prototype.
21272 Update copyright notice.
21274 * s-tassta.adb (Task_Wrapper): Declare the exception registration
21275 record and initialize it by calling __gnat_install_SEH_handler.

21285 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
21286 [VMS]: Add translations for g-enblsp.adb.
21288 * s-asthan-vms.adb: Removed.
21289 * s-asthan-vms-alpha.adb: Added.
21291 2005-02-09 Pascal Obry <obry@adacore.com>

21300 -shared-libgcc is now used by default on some systems (e.g. linux with
21302 Remove references to Makefile.prolog/generic, no longer used.
21304 2005-02-09 Vincent Celier <celier@adacore.com>
21306 * prj-makr.adb (Process_Directory): Put file name in canonical case
21307 before matching against the patterns.
21308 If gnatname has been invoked as <prefix>-gnatname
21309 then invoke the compiler as <prefix>-gcc, not just "gcc".
21311 2005-02-09 Ed Schonberg <schonberg@adacore.com>
21313 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
21314 with expansion disabled. The actual subtype is needed among other
21315 places when the selected component appears in the context of a loop
21316 bound, and denotes a packed array.
21317 (Operator_Check): Always use the first subtype in the
21318 error message, to avoid the appearance of internal base types.
21319 (Transform_Object_Operation): Copy each actual in full
21320 to the parameter associations of the constructed call, rather than
21321 using the shallow copy mechanism of New_Copy_List. This ensures that
21322 the chaining of named associations is done properly.
21323 (Complete_Object_Operation): Rewrite node, rather than
21324 replacing it, so that we can trace back to the original selected
21327 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
21328 and calls that use object notation, if the called function is not
21329 declared in a withed unit, place the elaboration constraint on the
21330 unit in the context that makes the function accessible.

22105 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
22106 fields claimed addressable still have to be bitfields. Use
22107 value_factor_p instead of a raw binop construction to check for the
22108 position's alignment.

22115 Ed Schonberg <schonberg@adacore.com>
22117 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
22118 with an implicit dereference as its prefix, use
22119 Insert_Explicit_Dereference instead of merely rewriting the prefix into

22121 prefix is generated, if appropriate.
22123 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
22124 dereference is rewritten to an explicit one, generate a reference to
22125 the entity denoted by its prefix using the original prefix node, so

22127 access value, if appropriate.
22129 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
22130 emitting 'assigned but never read' warning on a variable on the basis

22146 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
22147 subprogram which is Imported with convention Intrinsic if an
22148 External_Name argument is specified.
22149 (Process_Import_Or_Interface): Properly diagnose link name argument.
22150 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

22175 PolyORB_Support.Build_Stub_Type): New subrograms containing the
22176 PCS-specific part of Add_Stub_Type.

22206 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
22207 and the Has_Pragma_Unreferenced flag for each formal before analyzing
22208 the body, to ensure that warnings are properly emitted for each accept
22209 statement of a given task entry.

22231 (Remove_Next_Debug): Same fix
22233 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
22234 maintain back pointers now, though we did not used to, and comments

22241 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
22242 used to record an implicit dereference as a read operation on its
22243 prefix when operating under -gnatc. Necessary to avoid spurious
22244 'variable assigned but never read' warnings in that mode.
22245 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
22246 is a non-overloaded implicit dereference, call the above subprogram to
22247 ensure proper recording of references.
22249 2004-12-07 Gary Dismukes <dismukes@adacore.com>
22251 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

22301 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
22302 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
22303 and -eit to -ept. Added qualifier

22312 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
22313 internal implementation unit GNAT.Sockets.Thin,
22314 as their usage for sockets is non-portable (using the read and write

22341 2004-11-21 Andreas Jaeger <aj@suse.de>
22343 * stylesw.adb: Change Style_Check_Subprogram_Order to
22344 Style_Check_Order_Subprograms.
22346 2004-11-18 Arnaud Charlet <charlet@adacore.com>
22348 * adaint.h, adaint.c
22349 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
22351 Add also a cast to kill another warning.
22352 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
22353 parameter with the priority class of the parent process instead of
22354 always using the NORMAL_PRIORITY_CLASS.
22355 (__gnat_dup): New function.
22356 (__gnat_dup2): New function.
22357 (__gnat_is_symbolic_link): Enable the effective body of this
22358 function when __APPLE__ is defined.
22360 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
22363 2004-11-18 Olivier Hainque <hainque@adacore.com>
22365 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
22366 address of which may be used to represent "others" and "all others"
22367 choices in exception tables, instead of the current harcoded
22368 (void *)0 and (void *)1.
22369 (Setup_Exception): Do nothing in the GNAT SJLJ case.
22371 * gigi.h (others_decl, all_others_decl): New decls representing the
22372 new Others_Value and All_Others_Value objects.
22373 (struct attrib): Rename "arg" component as "args", since GCC expects a
22374 list of arguments in there.
22376 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
22377 corresponding objects exported by a-exexpr, instead of hardcoded dummy
22380 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
22381 others_decl and all_others_decl instead of hardcoded dummy addresses
22382 to represent "others" and "all others" choices, which is cleaner and
22383 more flexible with respect to the possible eh pointer encoding policies.
22385 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
22386 (process_attributes): Account for the naming change of the "args"
22387 attribute list entry component.
22389 * decl.c (build_attr_list): Rename into prepend_attributes to allow
22390 cumulating attributes for different entities into a single list.
22391 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
22392 attributes for the current entity and propagate first subtype
22393 attributes to other subtypes.
22394 <E_Procedure>: Attribute arguments are attr->args and not
22395 attr->arg any more.
22396 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
22397 argument provided, as this is what GCC expects. Use NULL_TREE instead
22400 2004-11-18 Robert Dewar <dewar@adacore.com>
22402 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
22403 Minor reformatting througout (including new function specs)
22404 Add ??? comments asking for clarification.
22406 2004-11-18 Thomas Quinot <quinot@adacore.com>
22408 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
22409 incomplete duplicate implementation of this subprogram from butil.
22411 2004-11-18 Thomas Quinot <quinot@adacore.com>
22413 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
22414 procedures factors the common processing for building an RPC receiver
22415 for an RCI package or an RACW type.
22416 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
22417 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
22418 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
22420 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
22422 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
22424 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
22425 distribution subprogram identifiers that are either subprogram numbers
22427 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
22428 string distribution identifiers assigned to a given subprogram.
22429 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
22430 (Add_RAS_Dereference_TSS): Add comments.
22431 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
22432 is not referenced yet because it will be used by the PolyORB DSA
22434 (Insert_Partition_Check): Remove fossile code.
22435 (First_RCI_Subprogram_Id): Document this constant.
22436 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
22438 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
22439 replaced with calls to Get_Library_Unit_Name_String. Previously there
22440 were several instances of the same code in different locations in the
22441 compiler; this checkin completes the replacement of all of these
22442 instances with calls to a common subprogram.
22443 Minor reformatting.
22445 * sem_dist.adb: Remove comment noting that RPC receiver generation
22446 should be disabled for RACWs that implement RASs.
22447 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
22449 * sem_util.ads, sem_util.adb (Has_Stream): New function
22450 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
22451 qualified name of a library unit into the name buffer.
22452 (Note_Possible_Modification): Generate a reference only
22453 if the context comes from source.
22455 * snames.ads (PCS_Names): New subtype corresponding to names of
22456 supported implementations of the Partition Communication Subsystem
22457 (PCS) (i.e. the runtime library support modules for the distributed
22460 2004-11-18 Robert Dewar <dewar@adacore.com>
22461 Ed Schonberg <schonberg@adacore.com>
22463 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
22464 (Has_Rep_Pragma): New function
22465 (Has_Attribute_Definition_Clause): New function
22466 (Record_Rep_Pragma): Moved here from sem_ch13.adb
22467 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
22469 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
22471 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
22472 (Expand_Pragma_Psect_Object): New procedure
22473 These procedures contain the revised and cleaned up processing for
22474 these two pragmas. This processing was formerly in Sem_Prag, but
22475 is more appropriately moved here. The cleanup involves making sure
22476 that the pragmas are properly attached to the tree, and that no
22477 nodes are improperly shared.
22479 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
22480 pragmas to Exp_Prag, which is more appropriate.
22481 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
22482 check for duplicates Remove use of Is_Psected flag, no longer needed.
22483 Use new Make_String_Literal function with string.
22485 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
22486 that are functions return universal values, that have to be converted
22487 to the context type.
22488 Use new Make_String_Literal function with string.
22489 (Get_Stream_Convert_Pragma): New function, replaces the use of
22490 Get_Rep_Pragma, which had to be kludged to work in this case.
22492 * freeze.adb: Use new Has_Rep_Pragma function
22494 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
22495 function with string.
22496 Use new Has_Rep_Pragma function.
22498 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
22501 2004-11-18 Robert Dewar <dewar@adacore.com>
22503 * errout.ads, errout.adb: (First_Sloc): New function
22505 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
22506 check (-gnatyx) instead of being included as a redundant construct
22509 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
22510 Style_Check_Order_Subprograms.
22512 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
22513 stylesw.adb: Add Style_Check_Xtra_Parens
22515 * usage.adb: Add line for -gnatyx (check extra parens)
22517 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
22519 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22520 Robert Dewar <dewar@adacore.com>
22522 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
22523 discriminant of a constrained subtype, analyze the copy of the
22524 corresponding constraint, because in some cases it may be only
22525 partially analyzed.
22526 Removes long-lived ??? comments.
22528 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
22529 handled controlled or secondary-stack expressions within the
22530 iteration_scheme of a loop.
22532 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
22533 bounds that may contain functions calls, to prevent memory leaks when
22534 the bound contains a call to a function that uses the secondary stack.
22535 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
22536 generate temporaries for loop bounds that might contain function calls
22537 that require secondary stack and/or finalization actions.
22539 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
22540 selected component and the selector is overloadable (not just a
22541 function) treat as function call, Analyze_Call will disambiguate if
22543 (Analyze_Selected_Component): Do not generate an actual subtype for the
22544 selected component if expansion is disabled. The actual subtype is only
22545 needed for constraint checks.
22546 (Analyze_Allocator): If restriction No_Streams is set, then do
22547 not permit objects to be declared of a stream type, or of a
22548 composite type containing a stream.
22550 * restrict.ads: Remove the a-stream entry from Unit_Array, since
22551 No_Streams no longer prohibits with'ing this package.
22553 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
22554 discriminants, but the parent base has unknown discriminants, there is
22555 no discriminant constraint to inherit. Such a discrepancy can arise
22556 when the actual for a formal type with unknown discriminants is a
22557 similar private type whose full view has discriminants.
22558 (Analyze_Object_Declaration): If restriction No_Streams is set, then
22559 do not permit objects to be declared of a stream type, or of a
22560 composite type containing a stream.
22562 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22564 * exp_dbug.ads: Update documentation to reflect simpler encoding for
22565 protected operations.
22567 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
22568 generated name, it complicates decoding in gdb and hinders debugging
22569 of protected operations.
22570 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
22571 flag for the protected entry barrier function.
22572 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
22573 flag for the protected entry function.
22575 2004-11-18 Nicolas Setton <setton@adacore.com>
22577 * expect.c: Define __unix__ when __APPLE__ is defined.
22579 * Makefile.in: Inform the value of the variable GMEM_LIB in the
22580 Darwin-specific section.
22582 * lang-specs.h: Change the placement of the %1 marker.
22583 Works around the fact that gcc adds -fPIC by default under Darwin.
22585 2004-11-18 Ed Schonberg <schonberg@adacore.com>
22587 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
22588 type of the object with the packed array type, set the Analyzed flag
22589 on the object if it is an entity or simple indexed component, to avoid
22590 spurious type errors.
22592 2004-11-18 Gary Dismukes <dismukes@adacore.com>
22594 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
22595 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
22596 separate line from the version message.
22598 2004-11-18 Ed Falis <falis@adacore.com>
22600 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
22602 (init_float): Eliminate initialization of floating point status for
22603 AE653. The instructions have no effect for vThreads.
22605 2004-11-18 Vincent Celier <celier@adacore.com>
22607 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
22608 gnatbind is invoked with -shared.
22610 2004-11-18 Jose Ruiz <ruiz@adacore.com>
22612 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
22613 for Detect_Blocking which is redundant with the check done within the
22614 procedure Protected_Single_Entry_Call.
22615 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
22616 Detect_Blocking which is redundant with the check done within the
22617 procedure Protected_Single_Entry_Call.
22619 2004-11-18 Vincent Celier <celier@adacore.com>
22621 * makegpr.adb (Compile): Put the compiling switches (in package
22622 Compiler and on the command line) immediately after "-c", instead of
22623 at the end of the command line invocation of the compiler, when
22624 compiling a non-Ada file.
22625 (Build_Global_Archive): When there is no need to rebuild the archive,
22626 set Global_Archive_Exists, so that the archive is passed to the linker
22629 2004-11-18 Robert Dewar <dewar@adacore.com>
22630 Sergey Rybin <rybin@adacore.com>
22633 Remove extra paren check from list of checks for redundant constructs
22634 Add documentation of new -gnatyx style check (check extra parens)
22635 Remove paragraph about gnatelim debug options.
22637 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
22638 objects rather than forbidding dependencies on the package Ada.Streams.
22640 * sinfo.ads: Add ??? note that we should document pragmas passed to
22643 * g-expect.ads: Fix a few typos in the comments.
22645 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
22647 * misc.c (gnat_handle_option): Use %< and %> for quoting in
22650 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
22652 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
22654 2004-11-07 Andreas Schwab <schwab@suse.de>
22656 * Makefile.in (install-gnatlib): Remove spurious hyphen.
22658 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
22661 * Makefile.in (darwin): Set soext to .dylib.
22663 2004-10-26 Vincent Celier <celier@gnat.com>
22664 Thomas Quinot <quinot@act-europe.fr>
22666 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
22667 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
22668 there is no use of GNAT.Sockets.Constants.
22669 Remove remaining pragma Import for C_Write
22670 Remove C_Read and C_Write from internal implementation unit
22671 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
22672 the read and write functions from the system runtime library is fine
22673 on UNIX but won't work under Windows).
22675 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
22676 (Check_Selector): Use C_Recv instead of C_Read.
22677 Selectors are the GNAT.Sockets abstraction to perform a select()
22678 call on a set of descriptors. To allow abortion of an ongoing
22679 select operation, some data is written to a dedicated socket that
22680 is always monitored.
22681 Under Windows, the write and read library functions cannot operate
22682 on sockets, so we need to use send and recv instead, which is portable
22683 across all supported platforms.
22685 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
22686 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
22687 (using the read and write functions from the system runtime library is
22688 fine on UNIX but won't work under Windows).
22690 2004-10-26 Nicolas Setton <setton@act-europe.fr>
22692 * mlib-tgt-darwin.adb: New file.
22694 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
22695 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
22696 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
22697 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
22700 * Makefile.in: Add support for building shared libraries under Darwin.
22701 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
22702 the low level EH init subprogram to be called from __gnat_initialize.
22704 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
22705 indicates which options to pass to the archive indexer.
22707 * mlib-utl.adb: Add support for calling ranlib with additional
22708 options. This is needed for instance under Mac OS X.
22709 (Ranlib_Options): New global variable, used to store the potential
22710 options to pass to ranlib.
22711 (Ar): Use Ranlib_Options when spawning ranlib.
22712 (Initialize): Set the value of ranlib option.
22714 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
22716 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
22717 instead of 8K, to reflect the real potential needs for stack-checking
22720 2004-10-26 Pascal Obry <obry@gnat.com>
22722 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
22724 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
22725 Windows only the initial thread stack size can be set so it is good to
22726 start we a low stack size.
22727 The OS will adjust the size as needed.
22729 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
22730 Nicolas Setton <setton@act-europe.fr>
22732 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
22733 "__unix__" instead of "unix".
22734 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
22735 sections were just mistakenly ignored. The former is
22736 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
22737 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
22738 of hpux. This prevents an unwanted definition of the symbol
22739 convert_addresses in adaint.o.
22741 2004-10-26 Gary Dismukes <dismukes@gnat.com>
22743 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
22744 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
22746 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22748 * a-filico.ads, a-filico.adb: fix incorrect header.
22750 2004-10-26 Javier Miranda <miranda@gnat.com>
22752 * a-ststio.ads: Fix typo in identifier
22754 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22756 * sem_ch4.adb: Minor reformatting.
22758 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22760 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
22761 enabled, check the result of unary and binary operations when the
22762 expression is the right-hand side of an assignment.
22764 2004-10-26 Vincent Celier <celier@gnat.com>
22766 * clean.adb (Delete): Do not output warnings when in quiet output and
22767 not in verbose mode.
22768 (Force_Deletions): New Boolean flag, defaulted to False
22769 (Delete): Only delete a file if it is writable, and when
22770 Force_Deletions is True.
22771 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
22772 (Usage): Line for new switch -f
22773 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
22776 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
22778 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
22779 JM type only if its size matches that of the wrapper. When a size is
22780 prescribed and the field is not aliased, remove the wrapper of a JM
22781 type only if the size is not greater than that of the packed array.
22782 (gnat_to_gnu_entity): Change the extension of packed array wrappers
22785 2004-10-26 Geert Bosch <bosch@gnat.com>
22787 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
22788 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
22789 (Pred): Implement in terms of Succ.
22791 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22793 * exp_aggr.adb (Safe_Component): An aggregate component that is an
22794 unchecked conversion is safe for in-place use if the expression of the
22795 conversion is safe.
22796 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
22797 be expandable in place even if the aggregate does not come from source.
22798 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
22799 designated object of an allocator in place, rather than building it
22800 first on the stack. The previous scheme forces a full copy of the array,
22801 and may be altogether unsusable if the size of the array is too large
22802 for stack allocation.
22804 2004-10-26 Robert Dewar <dewar@gnat.com>
22806 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
22807 compares if the component is atomic.
22809 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
22810 array assignment if the component type is atomic.
22812 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22813 Eric Botcazou <ebotcazou@act-europe.fr>
22815 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
22816 is aliased and is a by_reference type, do not pass by copy.
22817 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
22818 detect whether the call is in the right side of an assignment or
22819 the expression of an object declaration. Recurse on component
22820 association within aggregates.
22821 Call it in the condition that determines whether the temporary is
22822 necessary for correct stack-checking.
22824 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22826 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
22827 RACW_Type, used in the PolyORB version.
22828 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
22829 version and the GARLIC version.
22831 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
22832 Rename RCI_Info to RCI_Locator for better consistency between the
22833 GARLIC and PolyORB versions of the distributed systems annex.
22834 (DSA_Implementation_Name): This enumeration lists the possible
22835 implementations of the Partition Communication Subsystem for the
22836 Distributed Systems Annex (DSA). The three available implementations
22837 are the dummy stub implementation (No_DSA), and two versions based on
22838 two different distribution runtime libraries: GARLIC and PolyORB. Both
22839 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
22841 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
22844 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
22845 between the GARLIC and PolyORB versions of the distributed systems
22847 Remove RE_Unbounded_Reclaim_Pool since it is unused.
22849 2004-10-26 Gary Dismukes <dismukes@gnat.com>
22851 * gnat1drv.adb: Suppress calling the back end when
22852 Frontend_Layout_On_Target is true.
22854 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22856 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
22857 Set_Read_Only): New subprograms.
22858 These new routines allow the user to set or unset the Owner execute
22859 and Owner write permission flags on a file.
22861 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
22862 GNAT.OS_Lib.Set_Executable instead of rolling our own.
22864 2004-10-26 Matthew Gingell <gingell@gnat.com>
22866 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
22868 2004-10-26 Pascal Obry <obry@gnat.com>
22870 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
22871 memory before the faulting page we properly test the process read
22872 access for this address using appropriate Win32 routine.
22873 (HPUX sections): guard with "__hpux__" instead of "hpux".
22875 2004-10-26 Robert Dewar <dewar@gnat.com>
22877 * lib-xref.adb (Generate_Reference): Don't complain about reference to
22878 entry parameter if pragma Unreferenced set, since we do not properly
22879 handle the case of multiple parameters.
22881 2004-10-26 Vincent Celier <celier@gnat.com>
22883 * prj-env.adb: (Contains_ALI_Files): New Boolean function
22884 (Ada_Objects_Path.Add): For a library project, add to the object path
22885 the library directory only if there is no object directory or if the
22886 library directory contains ALI files.
22887 (Set_Ada_Paths.Add.Recursive_Add): Ditto
22889 2004-10-26 Vincent Celier <celier@gnat.com>
22891 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
22892 extension of library projects.
22894 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
22895 path defaults to ".:<prefix>/lib/gnat".
22896 (Parse): For an extending all project, allow direct import of a project
22897 that is virtually extended.
22899 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
22900 the specified name is directly imported, return its ID. Otherwise, if
22901 an extension of this project is imported, return the ID of the
22904 2004-10-26 Robert Dewar <dewar@gnat.com>
22906 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
22907 (Sub3): New procedure, used by Scaled_Divide
22908 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
22909 correct more than one instance of failure to propagate carries
22911 (Double_Divide): Handle overflow case of largest negative number
22912 divided by minus one.
22914 * s-arit64.ads (Double_Divide): Document that overflow can occur in
22915 the case of a quotient value out of range.
22918 2004-10-26 Robert Dewar <dewar@gnat.com>
22920 * s-bitops.adb (Bit_Eq): Remove redundant check.
22922 * s-bitops.ads: Minor comment updates
22923 Change some occurrences of Address to System.Address
22925 * s-carsi8.ads: Fix minor cut-and-paste error in comments
22927 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22929 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
22930 accessibility check to prefix that is a protected operation.
22932 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22934 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
22935 empty, post message on stub.
22937 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22938 Javier Miranda <miranda@gnat.com>
22940 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
22941 current instance appears within a unit that is directly in the context
22943 Used to determine whether the body of the instance should be analyzed
22944 immediately after its spec, to make its subprogram bodies available
22945 for front-end inlining.
22946 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
22947 constraint is not allowed on the component type (AARM 12.5.3(3))
22949 2004-10-26 Cyrille Comar <comar@act-europe.fr>
22951 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
22952 'Storage_Pool): enhance, document & limit detection of non-sharable
22955 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
22957 * s-pooglo.ads: Add more documentation now that this pool is properly
22960 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22962 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
22963 or protected type with discriminants, do not constrain the
22964 corresponding record type if the subtype declaration has no
22965 discriminant constraints. This can be the case in source code, or in
22966 the subtype declaration created to rename an actual type within an
22969 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22971 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
22972 different kind of stub (possibly wrong name for file), do not check
22974 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
22975 includes call to some function that returns an unconstrained type, do
22978 2004-10-26 Ed Schonberg <schonberg@gnat.com>
22980 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
22981 appear in the code for the main unit. Dependencies among units in the
22982 context of the main unit are established when those other units are
22983 compiled. Otherwise spurious elaboration constraints can generate
22984 incorrect elaboration circularities.
22986 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
22987 Ed Schonberg <schonberg@gnat.com>
22989 * sem_util.adb (Is_Aliased_View): Defend against the case where this
22990 subprogram is called with a parameter that is not an object name. This
22991 situation arises for some cases of illegal code, which is diagnosed
22992 later, and in this case it is wrong to call Is_Aliased, as that might
22993 cause a compiler crash.
22994 (Explain_Limited_Type): Refine previous fix to include
22995 inherited components of derived types, to provide complete information.
22997 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
22998 is the prival for a protected object.
22999 It is necessary to mark this entity as a variable, in addition to
23000 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
23001 modified to avoid checking the Aliased flag on entities that are not
23002 objects. (Checking that flag for non-objects is erroneous and could
23003 lead to a compiler crash).
23005 2004-10-26 Robert Dewar <dewar@gnat.com>
23007 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
23008 X_Frac = 0.5, then we know that the number X must be positive.
23009 (Succ): Remove the same redundant test, and also fix the primary test
23010 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
23012 (Decompose): Add fuller comments to spec
23014 2004-10-26 Pascal Obry <obry@gnat.com>
23016 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
23017 validity (process must have read access). Set to 0 in all other cases.
23018 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
23019 violation on Win32.
23020 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
23021 segmentation violation.
23023 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
23025 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
23026 whose type is a constructed subtype of an aliased object with an
23027 unconstrained nominal subtype, convert the actual to the constructed
23028 subtype before taking its address.
23030 2004-10-26 Vincent Celier <celier@gnat.com>
23032 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
23033 (Is_Path_Name_Case_Sensitive): New function
23035 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
23036 (Base_Name, Simple_Name, Current_Directory, Compose,
23037 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
23040 2004-10-26 Cyrille Comar <comar@act-europe.fr>
23041 Vasiliy Fofanov <fofanov@act-europe.fr>
23042 Vincent Celier <celier@gnat.com>
23044 * gnat_ugn.texi: Generalize "finding memory problems" section into a
23045 "memory management issues" section and document some of the useful
23046 memory pools provided as part of the GNAT library.
23047 Remove "virtual" from declaration of A::method2 in
23048 the simple example of Ada/C++ mixed system.
23049 Library Projects may be virtually extended: their virtual extensions
23050 are not Library Projects.
23051 Added section on extending project hierarchies.
23053 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
23055 * adaint.c (__gnat_get_libraries_from_registry): Cast value
23057 (__gnat_portable_spawn): Remove const.
23059 * mingw32.h (MAXPATHLEN): Check for previous definition.
23061 2004-10-17 Matthias Klose <doko@debian.org>
23063 * gnatvsn.ads: Set gnat library version to 4.0.
23065 2004-10-05 Vincent Celier <celier@gnat.com>
23067 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
23069 2004-10-04 Laurent GUERBY <laurent@guerby.net>
23072 * Makefile.in: Define and use RANLIB_FLAGS.
23074 2004-10-04 Pascal Obry <obry@gnat.com>
23076 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
23077 other x86 platforms).
23079 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
23081 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
23082 in general and triggers stack alignment adjustment for thread entry
23083 points on targets where this is necessary.
23085 2004-10-04 Bernard Banner <banner@gnat.com>
23088 * Makefile.in: Add section for powerpc linux
23089 Add variant i-vxwork-x86.ads
23091 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
23093 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
23095 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
23096 table registration calls when need be. Ensures no reference to the crt
23097 ctors symbol are issued in the SJLJ case, which avoids possible
23098 undefined symbol errors in the case of modules to be statically linked
23101 2004-10-04 Javier Miranda <miranda@gnat.com>
23103 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
23104 in-line the code corresponding to subprogram Analyze_Actuals. In
23105 addition, analyze the actuals only in case of subprogram call.
23107 2004-10-04 Ed Falis <falis@gnat.com>
23109 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
23111 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
23113 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
23114 in the documentation.
23116 2004-10-04 Robert Dewar <dewar@gnat.com>
23118 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
23120 (Analyze_Block_Statement): Add circuitry to detect following dead code
23121 (Check_Unreachable_Code): Handle case of block exit
23123 2004-10-04 Robert Dewar <dewar@gnat.com>
23125 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
23126 (XMatchD): Avoid warning for Logic_Error call
23128 2004-10-04 Robert Dewar <dewar@gnat.com>
23130 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
23131 consider expressions buried within a procedure actual to be an actual.
23132 This caused some blowups with uses of packed slices within a procedure
23135 2004-10-04 Robert Dewar <dewar@gnat.com>
23137 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
23138 longer need to be initialized to zero.
23139 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
23140 initialized to zero.
23142 * checks.adb (Expr_Known_Valid): Packed arrays are now always
23143 considered valid, even if the representation is modular. That's correct
23144 now that we no longer initialize packed modular arrays to zero.
23146 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
23147 suffixes. These are now documented as the only cases in which the
23148 debugger ignores outer records.
23149 Previously, the spec allowed arbitrary suffixes for this purpose.
23150 Change name of LJM to JM for packed array pad records
23151 Create separate section on packed array handling, and add a whole new
23152 set of comments to this section describing the situation with packed
23153 modular types and justification requirements depending on endianness.
23155 2004-10-04 Robert Dewar <dewar@gnat.com>

23168 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23170 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
23171 Inline_Always when in Configurable_Run_Time mode.
23173 * sem_prag.adb (Process_Convention): If entity is an inherited
23174 subprogram, apply convention to parent subprogram if in same scope.
23175 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
23176 when in Configurable_Run_Time mode.
23178 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23180 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
23181 class_wide type after component list has been inherited.

23185 * sem_ch12.adb (Check_Generic_Actuals): New predicate
23186 Denotes_Previous_Actual, to handle properly the case of a private
23187 actual that is also the component type of a subsequent array actual.
23188 The visibility status of the first actual is not affected when the
23189 second is installed.
23190 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
23191 make fully recursive the treatment of formals of packages declared
23193 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
23194 the above on exit from an instantiation.
23195 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
23196 current instantiation which is now complete.
23197 (Analyze_Package_Instantiation): No instantiated body is needed if the
23198 main unit is generic. Efficient, and avoid anomalies when a instance
23199 appears in a package accessed through rtsfind.
23201 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23203 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
23204 do not generate a declaration for a temporary if the call is part of a
23205 library-level instantiation.
23207 2004-10-04 Ed Schonberg <schonberg@gnat.com>
23209 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
23210 searching for a limited component to flag.
23212 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
23213 expansion of Input, to account for the fact that the implicit call
23214 generated by the attribute reference must freeze the user-defined
23215 stream subprogram. This is only relevant to 'Input, because it can
23216 appear in an object declaration, prior to the body of the subprogram.
23218 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
23219 expansion can proceed and further errors uncovered.
23220 (Minor clean up): Fix cases of using | instead of \ for continuation

23234 stripped-down declaration for the type of the inner field when making
23237 * utils.c (finish_record_type): Do not compute the size in units
23238 incrementally. Instead compute it once for the rep clause case.
23239 Use gcc_assert and gcc_unreachable.
23241 2004-10-04 Vincent Celier <celier@gnat.com>
23243 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character

23249 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
23250 (Extended_Project) only if Extended_Project is defined, to avoid
23252 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
23254 (Parse_Single_Project): Ditto.
23256 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
23257 Add_To_Project_Path for virtual projects.
23259 2004-10-04 Vincent Celier <celier@gnat.com>
23261 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

23265 parameter Options_2.
23267 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
23268 Build_Dynamic_Library with an empty Options_2.
23270 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
23273 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
23274 directory separator, if any.
23275 (Gprmake): Do not allow mains on the command line for library projects.
23276 Do not attempt to link when the project is a library project.
23277 (Library_Opts): New table to store Library_Options.
23278 (Build_Library): If Library_Options is specified, pass these options
23279 when building a shared library.
23281 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
23283 * s-tposen.adb (Service_Entry): The object must be always unlocked at

23304 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
23305 used to signal whether the compiler creates the required stacks and
23306 descriptors for the different tasks (when True) or it is done by the
23307 underlying operating system at run time (when False).
23308 It is initially set to False in all targets.
23310 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
23311 if it is supported by the target.
23312 (Make_Task_Create_Call): Pass the stack address if it has been
23313 previously created. Otherwise pass a Null_Address.

23318 statically allocated task stacks.
23320 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
23321 Stack_Address argument.
23322 Check that its value is equal to Null_Address because this target does
23323 not support the static stack allocation.
23325 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
23327 * usage.adb: Change "pragma inline" to "pragma Inline" in information
23330 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
23332 * exp_dist.adb: Split declaration of asynchronous flag out of
23333 Add_RACW_Read_Attribute.
23334 Minor reformatting for better alignment with PolyORB version.
23335 Store the entity for the asynchronous flag of an RACW, rather than the
23336 expression, in the asynchronous flags table. This will allow this flag
23337 to be used in other subprograms beside Add_RACW_Read_Attribute.
23339 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
23341 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

23344 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
23345 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
23346 sockets constant MSG_NOSIGNAL (Linux-specific).
23347 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
23348 all Send operations.
23349 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
23350 from trigerring SIGPIPE.
23351 Rename components to avoid clash with Ada 2005 possible reserved
23353 (Check_Selector): When the select system call returns with an error
23354 condition, propagate Socket_Error to the caller.

23364 instead do this at freeze time (we won't do it if there is an address
23366 Change "pragma inline" to "pragma Inline" in information and error
23368 Minor reformatting.
23370 * freeze.adb (Check_Address_Clause): Remove previous change, not the
23371 right way of doing things after all.
23372 (Freeze_Entity): For object, set Is_Public for imported entities
23373 unless there is an address clause present.
23375 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
23377 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
23378 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
23379 ensures proper handling of types with rep clauses, which might have
23380 their TYPE_SIZE set already.
23382 2004-09-21 Robert Dewar <dewar@gnat.com>
23384 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
23385 packed array types in both little- and big-endian cases. This change
23386 ensures that we no longer count on the unused bits being initialized
23387 for such types (and in particular ensures that equality testing will
23388 only read the relevant bits).
23389 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
23390 These changes mean that we no longer need to initialize small packed
23392 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
23393 optimization to an LJM field as to its parent field.
23395 * ada-tree.h, trans.c, utils.c, utils2.c:
23396 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
23398 2004-09-20 Jan Hubicka <jh@suse.cz>
23400 * utils.c (gnat_finalize): Remove.
23401 (end_subprog_body): Directly call cgraph_finalize_function;
23402 do not lower the nested functions.
23404 2004-09-20 Robert Dewar <dewar@gnat.com>
23407 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
23408 if an address clause is present, since that means that the Import
23411 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
23413 * 5tsystem.ads: Removed, no longer used.
23415 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
23416 Zack Weinberg <zack@codesourcery.com>
23418 * ada-tree.def: Use tree_code_class enumeration constants
23419 instead of code letters.

23439 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
23440 Convert the result to File_Size.
23442 * prj.ads: (Project_Error): New exception
23444 * prj-attr.adb: Except in procedure Initialize, Fail comes from
23445 Prj.Com, not from Osint.
23446 (Attrs, Package_Attributes): Tables moved to private part of spec
23447 (Add_Attribute, Add_Unknown_Package): Moved to new child package
23449 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
23450 Prj.Project_Error after call to Fail.
23451 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
23452 Fail. Check that package name is not already in use.
23454 * prj-attr.ads: Comment updates to indicate that all subprograms may be
23455 used by tools, not only by the project manager, and to indicate that
23456 exception Prj.Prj_Error may be raised in case of problem.
23457 (Add_Unknown_Package, Add_Attribute): Moved to new child package
23459 (Attrs, Package_Attributes): Table instantiations moved from the body to
23460 the private part to be accessible from Prj.Attr.PM body.
23462 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
23463 from new package Prj.Attr.PM.
23464 (Parse_Attribute_Declaration): Call Add_Attribute from new package
23467 * Makefile.in: Add prj-attr-pm.o to gnatmake object list

23515 pragmas recognized by GNAT.
23517 * gnat_rm.texi: Document pragma Detect_Blocking.
23519 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
23520 raise Program_Error if called from a protected operation.
23522 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
23523 the protected action nesting level.
23524 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
23525 protected action nesting level.
23526 (Unlock): When pragma Detect_Blocking is active decrease the protected
23527 action nesting level.
23529 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
23530 Protected_Action_Nesting.
23532 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
23533 Common_ATCB record. It contains the dynamic level of protected action
23534 nesting for each task. It is needed for checking whether potentially
23535 blocking operations are called from protected operations.
23536 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
23537 Detect_Blocking is active or not in the partition.
23539 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

23571 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
23572 insertion of the statement raising Program_Error. The run time
23573 contains the required machinery for handling that.
23575 * sem_util.ads: Change comment associated to procedure
23576 Check_Potentially_Blocking_Operation.
23577 This procedure does not insert a call for raising the exception because
23578 that is currently done by the run time.
23580 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
23582 * init.c: Add the global variable __gl_detect_blocking that indicates
23583 whether pragma Detect_Blocking is active (1) or not (0). Needed for
23584 making the pragma available at run time.
23585 (__gnat_set_globals): Pass and update the detect_blocking parameter.
23587 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
23588 pragma Detect_Blocking is active.
23590 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
23592 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
23593 DB is found in the ali file. Any unit compiled with pragma
23594 Detect_Blocking active forces its effect in the whole partition.
23596 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
23597 Detect_Blocking is active and delay is called from a protected
23600 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
23601 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
23602 Detect_Blocking is active (0 otherwise).
23603 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
23604 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
23607 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
23609 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
23610 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
23613 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
23614 (Register_Receiving_Stub): Add Subp_Info formal parameter.
23615 Update API in placeholder implemetation of s-parint to reflect changes
23616 in distribution runtime library.
23618 * sem_ch3.adb (Expand_Derived_Record): Rename to
23619 Expand_Record_Extension.
23621 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
23622 primitive operations of potentially distributed object types that have
23623 non-controlling anonymous access formals.
23625 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
23627 New implementation of expansion for remote access-to-subprogram types,
23628 based on the RACW infrastructure.
23629 This version of sem_dist is compatible with PolyORB/DSA as well as
23632 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
23633 Asynchrronous that applies to a remote access-to-subprogram type, mark
23634 the underlying RACW type as asynchronous.
23636 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
23637 __gnat_using_gnu_linker to 1.
23639 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
23640 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
23641 GNAT.Perfect_Hash_Generators, and remove the empty

23646 * exp_ch3.adb (Expand_Derived_Record): Rename to
23647 Expand_Record_Extension.
23648 (Build_Record_Init_Proc.Build_Assignment): The default expression in
23649 a component declaration must remain attached at that point in the
23650 tree so New_Copy_Tree copies it if the enclosing record type is derived.
23651 It is therefore necessary to take a copy of the expression when building
23652 the corresponding assignment statement in the init proc.
23653 As a side effect, in the case of a derived record type, we now see the
23654 original expression, without any rewriting that could have occurred
23655 during expansion of the ancestor type's init proc, and we do not need
23656 to go back to Original_Node.
23658 * exp_ch3.ads (Expand_Derived_Record): Rename to
23659 Expand_Record_Extension.
23661 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

23664 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
23665 New subprograms. Used to create a proxy tagged object for a remote
23666 subprogram. The proxy object is used as the designated object
23667 for RAS values on the same partition (unless All_Calls_Remote applies).
23668 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
23669 System.Partition_Interface.Get_Unique_Remote_Pointer.
23670 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
23671 Renamed from Add_RAS_*_Attribute.
23672 (Add_Receiving_Stubs_To_Declarations): Generate a table of local

23675 based on the RACW infrastructure.
23677 * exp_dist.ads (Copy_Specification): Update comment to note that this
23678 function can copy the specification from either a subprogram
23679 specification or an access-to-subprogram type definition.

23683 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
23684 in an instance, between an explicit subprogram an one inherited from a
23685 type derived from an actual.
23687 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
23688 add a polling call if the subprogram is to be inlined by the back-end,
23689 to avoid repeated calls with multiple inlinings.
23691 * checks.adb (Apply_Alignment_Check): If the expression in the address
23692 clause is a call whose name is not a static entity (e.g. a dispatching
23693 call), treat as dynamic.
23695 2004-09-09 Robert Dewar <dewar@gnat.com>
23697 * g-trasym.ads: Minor reformatting
23699 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

23708 2004-09-09 Pascal Obry <obry@gnat.com>
23710 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
23711 enable map file generation. Add the right option to generate the map
23712 file if Map_File is set to True.
23714 * gnatdll.adb (Gen_Map_File): New variable.
23715 (Syntax): Add info about new -m (Map_File) option.

23743 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
23744 of variable length temporaries for function return now that the
23745 back-end and gigi support it.

23802 * gnat-style.texi: Minor updates (note that boolean constants and
23803 variables are joined with AND/OR rather than short circuit forms).

23859 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
23860 target names rewrite to fix regressions with recent version of

23939 for a global aliased object with a variable size and an unconstrained
23940 nominal subtype, pretend there is no initializer if the one we have is
23941 incomplete, and avoid referencing an inexistant component in there. The

23966 unit, this is an attempt to inline a construct that is not available in
23967 the current restricted mode, so abort rather than trying to continue.
23969 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
23970 discriminants that rename those of the parent, recover names of
23971 original discriminants for the constraint on the full view of the

24002 returning C.int, to avoid using a derived boolean type.
24004 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

24033 ignore overflows on low and high bounds of an index to also account for
24034 differences in signedness between sizetype and gnu_index_subtype.
24035 These are as legitimate as the ones caused by a lower TYPE_PRECISION

28210 sem_util.adb: Minor reformatting
28212 * sem_ch12.adb: Add comment for previous change
28214 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
28216 * osint.adb (Executable_Prefix): Set Exec_Name to the current
28217 executable name when not initialized. Otherwise, use its current value.
28219 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
28220 initialize it to another executable name than the current one. This
28221 allows to configure paths for an executable name (gnatmake) different
28222 from the current one (gnatdist).
28224 2004-03-29 Ed Schonberg <schonberg@gnat.com>
28226 * exp_ch6.adb (Expand_Call): A call to a function declared in the
28227 current unit cannot be inlined if it appears in the body of a withed
28228 unit, to avoid order of elaboration problems in gigi.
28230 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
28231 information for protected (wrapper) operation as well, to simplify gdb
28234 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
28235 protected body, indicate that the entity for the generated spec comes
28236 from source, to ensure that references are properly generated for it.
28237 (Build_Body_To_Inline): Do not inline a function that returns a
28240 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
28241 apply convention to homonyms that are declared explicitly.
28243 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
28244 that renames an equality operator and the operands are overloaded,
28245 resolve them with the declared formal types, before rewriting as an
28248 2004-03-29 GNAT Script <nobody@gnat.com>
28250 * Make-lang.in: Makefile automatically updated
28252 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
28254 * memtrack.adb: Log realloc calls, which are treated as free followed
28257 2004-03-25 Vincent Celier <celier@gnat.com>
28259 * prj-makr.adb (Process_Directories): Detect when a file contains
28260 several units. Do not include such files in the config pragmas or
28261 in the naming scheme.
28263 * prj-nmsc.adb (Record_Source): New parameter Trusted_Mode.
28264 Resolve links only when not in Trusted_Mode.
28265 (Find_Sources, Recursive_Find_Dirs, Find_Source_Dirs, Locate_Directory):
28266 Do not resolve links for the display names.
28268 * prj-part.adb (Parse_Single_Project, Project_Path_Name_Of): Do not
28269 resolve links when computing the display names.
28271 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
28273 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
28274 attribute reference does not denote a subtype, it can be any
28275 expression that has a classwide type, potentially after an implicit
28276 dereference. In particular, the prefix can be a view conversion for
28277 a classwide type (for which Is_Object_Reference holds), but it can
28278 also be a value conversion for an access-to-classwide type. In the
28279 latter case, there is an implicit dereference, and the original node
28280 for the prefix does not verify Is_Object_Reference.
28282 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
28283 conversion of a discriminant-dependent component of a mutable object
28286 2004-03-25 Ed Schonberg <schonberg@gnat.com>
28288 * freeze.adb (Freeze_Entity): When an inherited subprogram is
28289 inherited, has convention C, and has unconstrained array parameters,
28290 place the corresponding warning on the derived type declaration rather
28291 than the original subprogram.
28293 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
28294 indication on renaming declaration, if formal has a box and actual
28297 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
28298 determine whether to generate an implicit or explicit reference to
28299 the renamed entity.
28301 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
28302 subprogram renaming comes from a defaulted formal subprogram in an
28305 2004-03-25 Gary Dismukes <dismukes@gnat.com>
28307 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
28308 value expressions to ensure that calls within a component definition
28309 will be checked (since those are evaluated during the record type's
28312 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
28314 * s-tpobop.adb: Code clean up:
28315 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated
28317 (PO_Do_Or_Queue): Remove duplicated code and use Requeue_Call.
28319 2004-03-25 Jose Ruiz <ruiz@act-europe.fr>
28321 * Makefile.in: Clean up in the ravenscar run time.
28323 2004-03-23 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28325 * decl.c (gnat_to_gnu_entity, case E_Access_Type): Pass value
28326 of No_Strict_Aliasing to build_pointer_type_for_mode.
28327 * utils.c (update_pointer_to): Walk pointer and ref chains.
28329 2004-03-22 Cyrille Comar <comar@act-europe.fr>
28331 * ali.ads: Fix Comment about Dynamic_Elab.
28333 * gnatls.adb (Output_Unit): Add output of many flags (Dynamic_Elab,
28334 Has_RACW, Is_Generic, etc.)
28335 (Output_Object, Gnatls): Take into account ALI files not attached to
28338 2004-03-22 Vincent Celier <celier@gnat.com>
28340 * gprep.adb: Change all String_Access to Name_Id
28341 (Is_ASCII_Letter): new function
28342 (Double_File_Name_Buffer): New procedure
28343 (Preprocess_Infile_Name): New procedure
28344 (Process_Files): New procedure
28345 (Gnatprep): Check if output and input are existing directories.
28346 Call Process_Files to do the real job.
28348 2004-03-22 Robert Dewar <dewar@gnat.com>
28350 * prj-env.adb, prj-nmsc.ads, prj-proc.ads,
28351 s-stache.ads, s-stache.adb: Comment updates. Minor reformatting.
28353 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
28355 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
28356 case when the source contains only comments.
28358 2004-03-22 Ed Schonberg <schonberg@gnat.com>
28360 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
28361 declaration for a child subprogram body that acts as a spec, indicate
28362 that the entity in the declaration needs debugging information.
28364 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
28365 full view if the subtype is created for a constrained record component;
28366 gigi has enough information to construct the record, and there is no
28367 place in the tree for the declaration.
28369 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
28370 serial number for the dummy body that is built for analysis, to avoid
28371 inconsistencies in the generation of internal names when compiling
28374 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
28376 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
28379 2004-03-22 GNAT Script <nobody@gnat.com>
28381 * Make-lang.in: Makefile automatically updated
28383 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28385 * decl.c (gnat_to_gnu_entity): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
28386 * trans.c (tree_transform, emit_index_check): Likewise.
28387 * utils.c (build_template): Likewise.
28388 (max_size, convert): Remove handling of WITH_RECORD_EXPR.
28389 (maybe_unconstrained_array, unchecked_convert): Likewise.
28390 * utils2.c (gnat_truthvalue_conversion, build_binary_op): Likewise.
28391 (build_unary_op): Likewise.
28392 (compare_arrays, build_allocator): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
28393 (fill_vms_descriptor): Likewise.
28394 (build_call_alloc_dealloc): Likewise.
28396 * gigi.h (build_call_alloc_dealloc): Alignment is unsigned.
28398 2004-03-20 Joseph S. Myers <jsm@polyomino.org.uk>
28401 * gnat_ug.texi: Add info directory category and entry.
28402 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
28403 gnat_ug_wnt.texi: Regenerate.
28405 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
28407 * ada-tree.h: Update copyright notice.
28408 Minor reformatting.
28410 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
28412 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
28413 as regular exception objects and not as mere integers representing the
28414 condition code. The latter approach required some dynamics to mask off
28415 severity bits, which did not fit well into the GCC table based model.
28416 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
28417 exception data objects. We don't it and it would conflict with the other
28418 external symbol we have to generate for such exceptions.
28420 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
28421 the special code for VMS exceptions, since these are now represented
28422 as regular exceptions objects.
28424 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28426 * decl.c (debug_no_type_hash): Remove.
28427 (gnat_to_gnu_entity, case E_Array_Type): Don't set and clear it.
28428 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
28430 2004-03-19 Laurent Guerby <laurent@guerby.net>
28432 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
28433 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
28435 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28437 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
28438 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
28439 (TYPE_RM_SIZE_INT): Directly use type.values.
28440 (TREE_LOOP_ID): Clean up check.
28441 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
28442 TYPE_VALUES, not TYPE_FIELDS.
28443 * trans.c (convert_with_check): Delay access of bounds of basetype
28444 until sure is numeric.
28446 2004-03-18 Arnaud Charlet <charlet@act-europe.fr>
28448 * 5atpopsp.adb: Remove RTEMS from list of platforms using this file.
28451 * 5ataprop.adb, 5ftaprop.adb, 5htaprop.adb, 5itaprop.adb, 5staprop.adb,
28452 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
28453 Specific.Set instead of direct call to e.g pthread_setspecific.
28455 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
28457 * adaint.c: Update comments.
28459 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
28460 GNATLIB_SHARED for FreeBSD.
28462 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
28464 * init.c [VxWorks]: Do not fix the stack size for the environment task.
28465 When needed (stack checking) the stack size is retrieved
28466 from the VxWorks kernel.
28468 * Makefile.in: Flag -nostdinc is required when building the run time
28469 for avoiding looking for files in the base compiler.
28470 Add the VxWorks specific version of the package body for
28471 System.Stack_checking.Operations (5zstchop.adb).
28473 * Make-lang.in: Add the object file for
28474 System.Stack_Checking.Operations.
28476 * Makefile.rtl: Add object file for the package
28477 System.Stack_Checking.Operations.
28479 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
28481 * s-stache.ads, s-stache.adb: Move the operations related to stack
28482 checking from this package to package System.Stack_Checking.Operations.
28483 This way, stack checking operations are only linked in the final
28484 executable when using the -fstack-check flag.
28486 2004-03-18 Doug Rupp <rupp@gnat.com>
28488 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
28491 * 5qsystem.ads, 5xcrtl.ads: New files.
28493 2004-03-18 Vincent Celier <celier@gnat.com>
28495 * prj.adb (Reset): Reset hash table Files_Htable
28497 * prj-env.adb (Source_Paths, Object_Paths): New tables.
28498 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
28499 the procedures Add_To_Path_File.
28500 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
28501 making sure that each directory is present only once and, for object
28502 dirs, when a directory already present is added, the duplicate is
28503 removed and the directory is always put as the last in the table.
28504 Write the path files at the end of these accumulations.
28506 * prj-nmsc.adb (Record_Source): Add source file name in hash table
28507 Files_Htable for all sources.
28509 * prj-proc.adb (Process): Remove restrictions between not directly
28510 related extending projects.
28512 2004-03-18 Emmanuel Briot <briot@act-europe.fr>

28515 (Find_Sources): Minor speed optimization.
28517 * prj-proc.ads, prj-proc.adb (Check, Recursive_Check, Process): New
28518 parameter Trusted_Mode.
28520 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
28522 * scn.adb (Determine_License): Take into account a degenerated case
28523 when the source contains only comments.
28525 2004-03-18 Ed Schonberg <schonberg@gnat.com>
28527 * sem_warn.adb (Check_References): For a warning on a selected
28528 component that does not come from source, locate an uninitialized
28529 component of the record type to produce a more precise error message.
28531 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
28533 * 3zsoccon.ads: Fix multicast options.
28535 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
28538 2004-03-15 Robert Dewar <dewar@gnat.com>
28540 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
28541 pragma used for a private type.
28543 * lib-xref.adb (Generate_Reference): Do not generate warning if
28544 reference is in a different unit from the pragma Unreferenced.
28546 * 5vtpopde.adb: Minor reformatting
28547 Fix casing of To_Task_ID
28549 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
28550 flag if we have an unchecked conversion to an access type in the same
28553 2004-03-15 Geert Bosch <bosch@gnat.com>
28555 * a-ngcoty.adb (Modulus): In alternate formula for large real or
28556 imaginary parts, use Double precision throughout.
28558 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
28559 we want to be able to compile run-time with -gnata for testing, but
28560 this may also be instantiated in user code that is compiled with -gnata.
28562 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
28564 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
28565 codes. Having a separate type for this is useful to enforce consistency
28566 throughout the various run-time units.
28567 (Exception_Data): Use Exception_Code for Import_Code.
28569 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
28570 Natural and Integer in various places.

28572 with the severity bits masked off.
28573 (Register_VMS_Exception): Handle the additional exception data pointer
28576 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
28577 component, now reflected by an exported accessor.
28578 (is_handled_by): New routine to compute whether the propagated
28579 occurrence matches some handler choice specification. Extracted out of
28580 get_action_description_for, and expanded to take care of the VMS
28582 (get_action_description_for): Use is_handled_by instead of an explicit
28583 complex condition to decide if the current choice at hand catches the
28584 propagated occurrence.
28586 * raise.h (Exception_Code): New type for C.
28588 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
28589 System.Standard_Library.Exception_Code, to allow references from the
28590 pragma import/export expander.
28592 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
28593 New accessors to allow easy access to GNAT exception data
28595 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
28596 redundant Handled_By_Others component, helper for the personality
28597 routine which will now be able to call the appropriate exception data
28600 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
28601 component of Standard_Exception_Type to be the closest possible to
28602 Exception_Code in System.Standard_Library, that we cannot get at this
28603 point. Expand a ??? comment to notify that this type node should
28604 probably be rewritten later on.
28606 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
28607 registration call to include a pointer to the exception object in the
28610 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
28611 instead of int and explicit bitmasks.
28613 2004-03-15 Vincent Celier <celier@gnat.com>
28615 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
28616 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
28618 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
28619 longer needed now that it is in the spec of
28620 System.Tasking.Task_Attributes.
28622 * adaint.h, adaint.c: (__gnat_create_output_file): New function
28624 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
28626 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
28628 * make.adb (Gnatmake): Do not check the executable suffix; it is being
28629 taken care of in Scan_Make_Arg.
28630 (Scan_Make_Arg): Add the executable suffix only if the argument
28631 following -o, in canonical case, does not end with the executable
28632 suffix. When in verbose mode and executable file name does not end
28633 with executable suffix, output the executable name, in canonical case.
28635 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
28636 to avoid warnings when instantiating Ada.Task_Attributes.
28639 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
28640 in the correct order.
28642 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
28643 redirect standard output and error to a file for the invocation of the
28644 compiler, then read the file.
28646 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
28647 directory, instead of the Value.
28648 (Find_Source_Dirs): Remove useless code & comments.
28650 2004-03-15 Ed Schonberg <schonberg@gnat.com>
28652 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
28653 tagged type is inherited, and the parent operation is not frozen yet,
28654 force generation of a freeze node for the inherited operation, so the
28655 corresponding dispatch entry is properly initialized.
28656 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
28657 when looking for user-defined equality operation.
28659 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
28660 boolean when locating primitive equality of tagged component.
28662 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
28663 bit-aligned field and the right-hand side a string literal, introduce
28664 a temporary before expanding assignment into a loop.
28666 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
28667 priority in full, to ensure that any expanded subepxressions of it are
28668 elaborated in the scope of the init_proc.
28670 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
28671 after object declaration, skipping over code that may have been
28672 generated for validity checks.
28674 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
28675 discriminants, ignore the known discriminants of its full view, if
28676 any, to check legality.
28678 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
28679 component if type has unknown discriminants.
28680 (Analyze_Private_Extension_Declaration): Discriminant constraint is
28681 null if type has unknown discriminants.
28683 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
28684 for end label when present.
28686 * s-fileio.adb (Open): When called with a C_Stream, use given name for
28687 temporary file, rather than an empty string.
28689 2004-03-15 Ed Falis <falis@gnat.com>
28691 * s-thread.adb: Removed, no longer used.
28693 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28695 * decl.c (target.h): Now include.
28696 (gnat_to_gnu_entity, case E_Access_Type): Use mode derived from ESIZE

28711 * 5ztpopsp.adb, 56tpopsp.adb: Fix spelling of Task_ID.
28713 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
28714 Insert_Dereference_Action when rewriting an implicit dereference into
28715 an explicit one, this will be taken care of during expansion of the
28716 explicit dereference.
28717 (Expand_N_Slice): Same. Always do the rewriting, even for the case
28718 of non-packed slices, since the dereference action generated by
28719 expansion of the explicit dereference is needed in any case.

29950 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity

30067 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
30068 N_String_Literal node always references an E_String_Literal_Subtype
30069 entity. This may not be true in the future.
30070 (Possible_Bit_Aligned_Component): Move processing of
30071 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
30073 * exp_ch6.adb (Expand_Thread_Body): Pick up

30075 by possible -Dnnn binder parameter.
30077 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
30078 (Type_May_Have_Bit_Aligned_Components): New function.

30118 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
30119 ineffective elaborate all pragmas on non-visible packages (this
30120 happened when a renamed subprogram was called). Now the elaborate all
30121 always goes on the package containing the renaming rather than the one
30122 containing the renamed subprogram.
30124 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
30125 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

30150 * make.adb (Gnatmake): Special process for files to compile/check when
30151 -B is specified. Fail when there are only foreign mains in attribute
30152 Main of the project file and -B is not specified. Do not skip bind/link

30184 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
30186 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
30187 all attributes, including read-only attribute.

30192 library naming scheme.

30223 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
30224 protected objects when allocator has a subtype indication, not a

30226 checked when limited aggregates are implemented.

30229 pure, emit warning.

30337 2003-12-11 Ed Falis <falis@gnat.com>
30339 * 5zinit.adb: Clean up.
30341 * 5zintman.adb (Notify_Exception): replaced case statement with a call
30342 to __gnat_map_signal, imported from init.c to support
30343 signal -> exception mappings that depend on the vxWorks version.
30346 Created and exported __gnat_map_signal to support signal -> exception
30347 mapping that is dependent on the VxWorks version.

30376 Minor reformatting throughout
30378 2003-12-11 Ed Schonberg <schonberg@gnat.com>
30380 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
30381 bounds of a loop, create a separate block in order to generate proper
30382 cleanup actions to prevent memory leaks.
30384 * sem_res.adb (Resolve_Call): After a call to
30385 Establish_Transient_Scope, the call may be rewritten and relocated, in
30386 which case no further processing is needed.
30388 * sem_util.adb: (Wrong_Type): Refine previous fix.
30389 Fixes ACATS regressions.

30401 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
30404 2003-12-08 Robert Dewar <dewar@gnat.com>
30406 * 7sintman.adb: Minor reformatting
30408 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
30409 standard linker options to get standard libraries linked. We now plan
30410 to provide dummy versions of these libraries to match the appropriate
30411 configurable run-time (e.g. if a library is not needed at all, provide
30412 a dummy empty library).
30414 * targparm.ads: Configurable_Run_Time mode no longer affects linker
30415 options (-L parameters and standard libraries). What we plan to do is
30416 to provide dummy libraries where the libraries are not required.
30418 * gnatbind.adb: Minor comment improvement
30420 2003-12-08 Javier Miranda <miranda@gnat.com>
30422 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
30423 aggregate in the parent. Otherwise constants with limited aggregates

30426 default initialized components.
30427 (Gen_Assign): In case of default-initialized component, generate a
30428 call to the IP subprogram associated with the component.

30434 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
30435 to indicate that the initialization call corresponds to a
30436 default-initialized component of an aggregate.
30437 In case of default initialized aggregate with tasks this parameter is
30438 used to generate a null string (this is just a workaround that must be
30439 improved later). In case of discriminants, this parameter is used to
30440 generate a selected component node that gives access to the discriminant
30443 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
30444 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
30445 allocated aggregates with default-initialized components.
30447 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
30448 the box notation is used in positional aggregates.

30490 Process nodes N_Comment.
30492 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
30493 without comments and there are some comments, set the flag
30494 Unkept_Comments to True.
30495 (Scan): If there are comments, set the flag Unkept_Comments to True and
30496 clear the comments.
30497 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment

30527 (Set_Comment_As_Token): New procedure
30529 * sinput-p.adb: Update Copyright notice
30530 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

30535 * sem_aggr.adb: Add dependence on Exp_Tss package
30536 Correct typo in comment
30537 (Resolve_Aggregate): In case of array aggregates set the estimated
30538 type of the aggregate before calling resolve. This is needed to know
30539 the name of the corresponding IP in case of limited array aggregates.
30540 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
30541 in case of default initialized array components.
30543 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

30563 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
30564 they are automatically generated by Make-lang.in and cause nothing but
30565 maintenance troubles.
30567 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
30569 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

30583 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
30584 to ensure that the kernel fills in the interrupted context structure
30585 before calling a signal handler, which is necessary to be able to
30586 unwind past it. Update the copyright notice.
30588 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
30590 * a-elchha.ads: New file.

30675 included in HIE_NONE_TARGET_PAIRS.
30677 2003-12-03 Ed Schonberg <schonberg@gnat.com>
30680 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
30681 is legal in an instance, because legality is cheched in the template.

30838 between signals and interrupts.
30839 Add to Unblocked_Signal_Mask the set of signals that are in
30843 Adding a check to see whether the Interrupt_ID we want to unmask is in
30844 the range of Keep_Unmasked (in procedure Interrupt_Self_Process). The
30845 reason is that the index type of the Keep_Unmasked array is not always
30846 Interrupt_ID; it may be a subtype of Interrupt_ID.
30848 2003-11-24 Gary Dismukes <dismukes@gnat.com>
30851 (Remove_Side_Effects): Condition constantness of object created for a

33607 xtreeprs.adb: Correct statements in comments about maintainership
33610 2002-09-23 Zack Weinberg <zack@codesourcery.com>
33612 * Make-lang.in (EXTRA_GNATBIND_OBJS): Add version.o.
33613 * Makefile.in (TOOLS_LIBS): Add ../../version.o.
33614 * gnatvsn.ads: Gnat_Version_String is now a function.
33615 * gnatvsn.adb: New file. When asked for Gnat_Version_String,
33616 copy the C version_string into a String and return it.
33617 * gnatcmd.adb, gnatkr.adb, gnatlbr.adb, gnatlink.adb,
33618 gnatls.adb,gnatmake.adb, gnatprep.adb, gnatpsta.adb:
33619 Remove pragma Ident (Gnat_Version_String). If this was the
33620 sole use of package Gnatvsn, remove the with statement too.
33621 * gnat1drv.adb: Tweak -gnatv output.
33623 2002-09-17 Richard Henderson <rth@redhat.com>
33625 * trans.c (tree_transform): Use real_ldexp not REAL_VALUE_LDEXP.
33626 * config/dsp16xx/dsp16xx.md (fixuns_trunchfhi2): Use real_2expN.
33627 * config/mips/mips.md (fixuns_truncdfsi2): Likewise.
33628 (fixuns_truncdfdi2, fixuns_truncsfsi2, fixuns_truncsfdi2): Likewise.
33629 * config/m68k/m68k.c (floating_exact_log2): Use real_exponent
33630 and real_2expN instead of a loop.
33631 * doc/tm.texi (REAL_VALUE_LDEXP): Remove.
33632 (REAL_VALUE_RNDZINT, REAL_VALUE_UNSIGNED_RNDZINT): Remove.
33634 2002-08-25 Andre Leis <a.leis@gmx.net>

33654 2002-07-15 Florian Weimer <fw@deneb.enyo.de>
33656 * make.adb (Add_Switch): Make Generic_Position a procedure. The
33657 function approach did not work well because of a side effect (the
33658 function call could reallocate the table which was being indexed
33659 using its result). Fixes ada/4851. [RESURRECTED]
33661 2002-07-01 Roger Sayle <roger@eyesopen.com>

34272 function approach did not work well because of a side effect (the
34273 function call could reallocate the table which was being indexed
34274 using its result). Fixes ada/4851.

34605 containing the name of the Ada Main Program. This string is mainly
34606 intended for the debugger.

34641 2001-12-17 Laurent Pautet <pautet@gnat.com>
34644 Fix comment of Shutdown_Socket and Close_Socket. These functions
34645 should not fail silently because if they are called twice, this
34646 probably means that there is a race condition in the user program.
34647 Anyway, this behaviour is consistent with the rest of this unit.
34648 When an error occurs, an exception is raised with the error message
34649 as exception message.

34802 reference nodes, since this field is used in such nodes.

35123 (Expand_N_Subprogram_Body): Reset Is_Pure for any subprogram that has

35988 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
35989 instead of simple checksum.
35990 (CRC_Match): new function.
35991 (CRC_Error): new constant.
35993 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
35994 a CRC now and not a simple checksum. A CRC uses lower-case hex
35995 letters, fixes ambiguity in parsing.
35997 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
35998 is what this variable will store.

36001 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
36002 rename All_Checksum_Match to All_CRC_Match. Change due to API
36003 renaming since now GNAT does not use a simple checksum but a
36004 CRC using GNAT.CRC32.
36006 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
36007 now and not anymore a simple checksum.

36046 * types.adb (Hex): Use lowercase for the letter part.
36048 * types.ads (Get_Hex_String): Returns the hexadecimal representation
36049 for a word. This is currently used only for CRC. In previous version,
36050 the checksum was using a representation with all letter being
36051 upper-case. With the new implementation (using CRC) we do not remove
36052 the 32th bit of the CRC, so we can have an upper-case starting letter
36053 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
36054 It is ambigous since the CRC was optional and could be followed by
36055 options like EB, EE. So now this routines uses lower-case letter for
36056 the hexadecimal representation. Strange enough only lower case letters
36057 where checked in Scan_ALI (even if this was not a possible case).
36059 * gnatvsn.ads (Library_Version): changed to 3.15a.
36061 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
36064 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
