24 generate an error when this package is instantiated from a
27 2007-11-07 Samuel Tardieu <sam@rfc1149.net>
29 * a-tasatt.adb: Type Wrapper should be declared in comment instead
30 of already declared type Node_Access.
31 Use 'Access instead of 'Unchecked_Access when applicable. Local
32 lifetime is the one of the package.
33 (Set_Value): W is allocated on the heap.
35 * g-socket.adb: Use 'Access instead of 'Unchecked_Access when
37 (Get_Socket_Option): Optlen formal of C_Getsockopt is of an anonymous

113 Add Unreferenced and Warnings (Off) pragmas for cases of
114 variables modified calls where they are IN OUT or OUT parameters and
115 the resulting values are not subsequently referenced. In a few cases,
116 we also remove redundant code found by the new warnings.

134 * ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
136 (Xref_Record): Change type for Line, since in the case of a reference to
137 a predefined entity (as happens for array index types), the line is set
139 Add support for parsing multiple array index types info, or
140 multiple inherited interfaces info. This information cannot be stored
141 in Xref_Entity_Record, which only supports a single instance of Tref_*,
142 and is therefore stored in the list of references instead. It has a
143 special treatement later on in tools that use this information.
145 2007-10-15 Tristan Gingold <gingold@adacore.com>
147 * debug.adb: Document use of -gnatd.a and -gnatd.I
149 * layout.adb: On OpenVMS -gnatd.a disables alignment optimization.
151 2007-10-15 Javier Miranda <miranda@adacore.com>
153 * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
154 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
155 care of access to class-wide interface types plus removal of bizarre
156 conversion of tagged object to access type (reported by Gary
157 Dismukes). After this patch there is no need to perform any
158 additional management on these nodes in Expand_Interface_Actuals.
160 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
161 that handles use of 'Access and 'Unchecked_Access applied to
162 actuals covering interface types. Such code is now
163 centralized in Expand_N_Attribute_Reference.
165 2007-10-15 Ed Schonberg <schonberg@adacore.com>
167 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
168 of tagged types whose ultimate ancestor is a CPP type.
169 (Freeze_Array_Type): For a packed array type, generate an initialization
170 procedure if the type is public, to handle properly a client that

199 * vx_stack_info.c: New file.
201 * i-forbla-unimplemented.ads: New file.
203 * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
204 for unsupported configurations; use it on VMS targets instead of the
206 (EXTRA_LIBGNAT_SRCS,EXTRA_LIBGNAT_OBJS for VxWorks): Include
207 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
208 used by VxWorks targets to have access to task-specific data and be
209 able to extract the stack boundaries for stack checking.
210 Use system-vms-ia64.ads on ivms.
212 * Make-lang.in: Update dependencies.
214 * sysdep.c (__gnat_get_stack_info): Move to a standalone file

226 the source is unknown.
228 * prj-ext.adb: Spelling error fix
230 * prj-nmsc.adb (Check_Ada_Name): Reject any unit that includes an Ada
231 95 reserved word in its name.
232 (Process_Project_Level_Array_Attributes): Process new attribute
235 * prj-part.adb (Parse_Single_Project): Do not check the name of the

241 (Process_Project_Tree_Phase_1): Set Success to False in case an error is
244 * prj-util.adb (Value_Of (In_Array)): When Force_Lower_Case_Index is
245 True, compare both indexes in lower case.

249 * rtsfind.adb: (Load_RTU): Turn off style checks for Load call
251 2007-10-15 Gary Dismukes <dismukes@adacore.com>
253 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
254 association for an access component, add an association with null as
255 the expression. Remove testing for array subtypes and the setting in
256 that case of Ctyp to the array component type, which prevented proper
257 inclusion of an association for null-initialized arrays. Collapse
258 condition that tests for array subtypes into just a test of
259 Is_Partially_Initialized_Type (which already covers arrays anyway).
261 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
263 * sem_ch12.adb: Minor code reformatting.
264 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to

276 * sem_ch4.adb: Minor code and comment reformatting.
277 (Analyze_Allocator): When the designated type of an unconstrained
278 allocator is a record with unknown discriminants or an array with
279 unknown range bounds, emit a detailed error message depending on the
280 compilation mode and whether the designated type is limited.
282 2007-10-15 Tristan Gingold <gingold@adacore.com>

445 Add a section on leap seconds control along with two entities used to
446 enable and disable leap seconds support. The array Leap_Second_Times is
447 now constant and contains hard time values pre-generated. Remove
448 all elaboration code used to populate the table of leap seconds.
451 Add entity Leap_Seconds_Support to the list of global run-time variables
452 along with a comment on its usage and values.
453 (Gen_Adainit_Ada): Add code to generate the declaration and import of

512 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
513 indirection added to the HT_Link component of the TSD. This is required
514 to statically allocate the TSD.
517 Minor reordering of the declarations in the private part. Required to
518 add a level of indirection to the contents of the TSD component HT_Link.
519 This is required to statically allocate the TSD.
521 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
522 Is_Statically_Allocated set from constant objects.
523 Do not make exported constants created by the compiler volatile.
524 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
527 * trans.c (Identifier_to_gnu): For constants, unshare initializers
528 before returning them.
530 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
531 public part of the package.
532 (Make_DT): Move HT_Link component out of the TSD record. For this
533 purpose Make_DT now declares a separate object that stores the
534 HT_Link value, and initializes the TSD component with the address
535 of this new object. The addition of this level of indirection is
536 required to statically allocate the TSD because the TSD cannot
537 have variable components.
538 (Expand_Interface_Conversion): Improve the expanded code.
539 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
541 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
542 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
543 if we are building static dispatch tables then we must not generate
544 extra code to register the primitive because the dispatch table will
545 be built at the end of the library package; otherwise we notify that

576 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
577 of these procedures are passed a function call that already has
578 build-in-place actuals (testing new flag
579 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
580 the case where processing continues.
581 (Expand_Call): If the call is generated from a thunk body then we
582 propagate the extra actuals associated with the accessibility
583 level of the access type actuals.

621 Is_Preelaborable_Expression.
622 (Has_Preelaborable_Initialization): In the case of a generic actual
623 subtype, (that is, Is_Generic_Actual is True), return the result of

653 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
654 be moved from the body to the private part of the spec.
655 (*): All subprograms now have an extra parameter with default value to
656 specify which parser should be used. For backward compatibility, it
657 defaults to parsing the command line of the application. They were also
658 modified to properly handle cases where each of the argument does not
659 start at index 1 (which is always true for Ada.Command_Line, but not
660 when processing any Argument_List).
661 (Free): New subprogram
662 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
663 Argument): New subprograms
664 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
665 special characters like ':', '=',... are now handled in a single place,
666 which makes the code more extensible eventually.
667 (Getopt, Full_Switch): When the switch was returned as part of the
668 special character '*', make sure it is prepended by the switch character
669 ('-' in general), so that the application knows whether "foo" or "-foo"
670 was specified on the command line.

1063 Thomas Quinot <quinot@adacore.com>
1065 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
1066 create an abstract subprogram in the case of 'Input. For 'Output we now
1067 create a real spec/body when the type is abstract, since it can
1068 potentially be called.
1069 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
1070 body for 'Output when the type is abstract (only the creation of the
1071 body for 'Input is excluded when the type is abstract).
1072 (Stream_Operation_OK): Add an additional condition in the return
1073 statement, so that False will be returned for TTS_Stream_Input if the
1074 associated tagged type is an abstract extension. Add comments for
1076 (Expand_N_Object_Declaration): For the case of a shared passive
1077 variable, insert init proc call only after the shared variable
1078 procedures have been processed, because the IP call needs to undergo
1079 shared passive variable reference expansion, which requires these
1080 procedures to be available (and elaborated).
1082 2007-09-10 Vincent Celier <celier@adacore.com>
1084 * prj-env.ads, prj-env.adb (Create_Mapping_File (Language)): Remove
1085 parameter Runtime_Project.
1087 2007-09-10 Ed Schonberg <schonberg@adacore.com>
1089 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
1090 given a box association, the type of the component is discriminated,
1091 and the value of the discriminant is the discriminant of the enclosing
1092 type, retrieve its value from the aggregate itself, where it must have
1095 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
1096 to remove other spurious ambiguities on arithmetic operations involving
1097 literals and addresses, on systems where Address is a visible integer
1098 type, when the operator is called in functional notation.
1099 (Try_Primitive_Operation): Within an instance, a call in prefixed form
1100 is legal when the types match, even if the operation is currently
1103 2007-09-10 Ed Schonberg <schonberg@adacore.com>
1105 * sem_ch12.adb (Build_Local_Package): A formal package with no
1106 associations is legal if all formals have defaults. It is not
1107 equivalent to a formal declared with a box.

1135 a debug renaming declaration specially.
1137 2007-09-08 Eric Botcazou <ebotcazou@adacore.com>
1139 * decl.c (gnat_to_gnu_entity) <Object>: Simplify the condition under
1140 which a constant renaming is treated as a normal object declaration.
1141 * trans.c (lvalue_required_p) <N_Slice>: New case, extracted from
1142 the N_Indexed_Component case.
1143 <N_Indexed_Component>: Fall through to above case.

1146 2007-09-08 Eric Botcazou <ebotcazou@adacore.com>
1148 * decl.c (make_packable_type): If the new type has been given BLKmode,

1158 get_action_description_for): Replace _Unwind_Word with _uleb128_t
1159 and _Unwind_SWord with _sleb128_t.

1170 2007-09-03 Nick Clifton <nickc@redhat.com>
1172 * Make-lang.in: Change copyright header to refer to version 3 of
1173 the GNU General Public License and to point readers at the

1214 (Mark_Non_Null): If the node for which we just generated an access check
1215 is a reference to an *in* parameter and the reference appears in the
1216 declarative part of a subprogram body, mark the node as known non null.
1218 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
1220 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the
1221 structure of E_Exception to reflect the new flag.
1222 (Is_Raised, Set_Is_Raised): New inlined routines.
1223 Update the usage of available flag to reflect the addition of Is_Raised.
1224 (Is_Raised, Set_Is_Raised): Bodies of new routines.
1225 (Write_Entity_Flags): Write the status of flag Is_Raised.
1226 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
1227 spurious ambiguities when integer literals appear in the context of an
1228 address type that is a visible integer type.
1230 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
1231 exceptions never being raised.
1232 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

1242 * exp_ch3.adb (Build_Record_Init_Proc): If there is a static
1243 initialization aggregate for the type, generate itype references for
1244 thetypes of its (sub)components, to prevent out-of-scope errors in gigi.
1246 2007-08-31 Gary Dismukes <dismukes@adacore.com>
1248 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
1249 library-level package renaming, pass the declaration associated with
1250 the renaming's special debug variable to Qualify_Entity_Names to ensure
1251 that its encoded name is properly qualified.
1253 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
1254 occurring in the list of entities to qualify, and do not attempt to
1255 traverse an entity list in that case. Variables associated with
1256 ` library-level package renamings can now occur in the table.
1258 * exp_dbug.ads: Revise documentation of the encoding for renaming
1261 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1263 * layout.adb (Layout_Type): Use Underlying_Type to determine whether an
1264 access type points to an unconstrained array.
1266 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
1268 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
1271 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect
1272 simple redundant qualifications. The check is performed whenever the
1273 expression is a non-overloaded identifier.
1274 (Resolve_Type_Conversion): Enchance the redundant type conversion check
1275 to include loop parameters.
1276 (Valid_Conversion): Avoid generation of spurious error message.
1278 2007-08-31 Bob Duff <duff@adacore.com>
1280 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
1281 concatenations of string literals into a single literal, in order to
1282 avoid very deep recursion in the front end, which was causing stack
1285 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
1286 string, and the right operand is a string literal (the case of "" &
1287 "..."), optimize by avoiding copying the right operand -- just use the
1288 value of the right operand directly.
1290 * stringt.adb (Store_String_Chars): Optimize by growing the
1291 String_Chars table all at once, rather than appending characters one by
1293 (Write_String_Table_Entry): If the string to be printed is very long,
1294 just print the first few characters, followed by the length. Otherwise,
1295 doing "pn(n)" in the debugger can take an extremely long time.
1297 * sem_prag.adb (Process_Interface_Name): Replace loop doing
1298 Store_String_Char with Store_String_Chars.
1300 2007-08-31 Vincent Celier <celier@adacore.com>
1302 * prj-attr.adb: Add new attribute Excluded_Source_Files

1312 clauses of subunits, ignore limited_with_clauses that are illegal and
1313 have not been fully analyzed.
1315 2007-08-31 Ed Schonberg <schonberg@adacore.com>
1317 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
1318 flag, for effiency. It is called when analyzing arithmetic operators
1319 and also for actuals in calls that are universal_integers. The flag is
1320 set for the predefined type address, and for any type or subtype
1323 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
1324 Universal_Integer, when the formal is a descendent of address and the
1325 call appears in user code.
1326 (Analyze_Selected_Component): if the prefix is a private extension, the
1327 tag component is visible.
1329 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an
1332 2007-08-31 Robert Dewar <dewar@adacore.com>

1362 with implementation.
1363 Documentation cleanup only.
1365 2007-08-31 Sergey Rybin <rybin@adacore.com>
1367 * vms_data.ads: Add new qualifier /STMT_NAME_ON_NEW_LINE for the new
1368 gnatpp '--separate-stmt-name' option.
1369 Add new qualifier /USE_ON_NEW_LIN for the new gnatpp '--use-on-new-line'
1372 * gnat_ugn.texi: Add description for the new gnatpp
1373 '--separate-stmt-name' and '--use-on-new-line' options.
1375 2007-08-31 Ben Elliston <bje@au.ibm.com>
1377 * Makefile.in (LIBGNAT_TARGET_PAIRS): Use system-linux-ppc64.ads
1378 when compiling for powerpc64-*-linux.
1379 * system-linux-ppc64.ads: New file.
1381 2007-08-22 Krister Walfridsson <cato@df.lth.se>

1386 2007-08-16 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
1388 * misc.c (gnat_type_max_size): Constify.
1390 2007-08-16 Gary Dismukes <dismukes@adacore.com>
1392 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
1393 associated with Standard_Debug_Renaming_Type, to be used as the type of
1394 the special variables whose names provide debugger encodings for
1395 renaming declarations.
1397 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
1398 (Set_Debug_Renaming_Link): Change to set Node25.
1399 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
1400 (Write_Field25_Name): Add case for E_Variable to output
1401 "Debug_Renaming_Link".
1402 (Write_Field23_Name): Correct the output string for "Limited_View".
1404 * exp_dbug.adb: Add with and use of Tbuild.
1405 (Debug_Renaming_Declaration): Replace creation of an enumeration type
1406 and literal with creation of a variable of type
1407 Standard_Debug_Renaming_Type whose name encodes both the renamed object
1408 and the entity of the renaming declaration.
1409 (Qualify_Entity_Name): Add the delayed qualification of the entity name
1410 part of the name of a variable that has a Debug_Renaming_Link.
1412 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
1413 special type to be associated with variables that provide debugger
1414 encodings for renaming declarations.
1416 2007-08-16 Gary Dismukes <dismukes@adacore.com>
1417 Ed Schonberg <schonberg@adacore.com>
1418 Javier Miranda <miranda@adacore.com>
1420 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
1421 ancestor part given by an aggregate to test for an unchecked conversion,
1422 since this can occur in some cases when the ancestor part is a function
1423 call, and we don't want to fall into the recursive call to this
1424 procedure in that case.
1426 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
1427 stream attributes on limited types to account for user-specified
1428 attributes as well as whether Input (resp. Output) becomes available
1429 due to Read (resp. Write) being available for the type. Change Boolean
1430 variable to the more accurate name
1431 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
1432 double-"not" predicate at beginning of return statement to more
1433 understandable form.
1435 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
1436 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
1437 in a block statement and use that as the first statement of the
1438 expanded return rather than incorrectly using the handled sequence as
1439 the first statement.
1441 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
1442 operation, generate an explicit freeze node for it rather than
1443 generating extra formals, to ensure that gigi has the proper order of
1444 elaboration for anonymous subtypes in the signature of the subprograms.
1445 (Build_In_Place_Formal): Move assertion to beginning of loop.
1446 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
1447 applied to a function call (occurs for some cases of 'Input).
1448 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
1449 applied to a function call (occurs for some cases of 'Input).
1451 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
1452 2005, generate an extended return statement enclosing the result object
1455 * freeze.adb (Freeze_Record_Type): Extend the current management of
1456 components that are access type with an allocator as default value: add
1457 missing support to the use of qualified expressions of the
1458 allocator (which also cause freezing of the designated type!)
1459 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
1460 dispatching operation, since extra formals may be needed by calls to
1461 build-in-place functions (such as stream 'Input).
1463 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
1464 formals for 'Constrained and accessibility level in the case of a
1465 predefined dispatching operation.
1467 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
1468 point, no need to find the parent node.
1470 2007-08-16 Javier Miranda <miranda@adacore.com>
1472 * exp_attr.adb (Attribute_Priority): Add missing support for entries
1475 2007-08-16 Javier Miranda <miranda@adacore.com>
1477 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
1478 is not really required and can introduce regression with the debugger.
1479 The original problem is fixed with the patch written for checks.adb.

1489 Including_Non_Switch set to False.
1490 (Gnatmake): For the compiler, call Test_If_Relative_Path with
1491 Including_Non_Switch set to False.
1493 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
1494 parameter Including_Non_Switch, defaulted to True. When
1495 Including_Non_Switch is False, options that are not switches and
1496 appear as relative path are not converted to absolute paths.

1516 (Has_With_Clause): New routine.
1518 2007-08-16 Ed Schonberg <schonberg@adacore.com>
1520 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
1521 generic for an enclosing instance is a global reference, even though
1522 its scope is the enclosing instance.

1525 Javier Miranda <miranda@adacore.com>
1527 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
1528 initialize a limited object.

1538 2007-08-16 Ed Schonberg <schonberg@adacore.com>
1540 * sem_disp.adb (Check_Dispatching_Operation): If the operation
1541 implements an operation inherited from a progenitor interface, verify
1542 that they are subtype-conformant.

1545 Bob Duff <duff@adacore.com>
1546 Nicolas Setton <setton@adacore.com>
1548 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
1549 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
1550 the statement which is being resolved comes from a predefined library
1551 unit, all non-predefined library interpretations are skipped.
1552 (Resolve_Op_Concat): If string concatenation was folded in the parser,
1553 but the "&" is user defined, give an error, because the folding would
1556 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
1557 the parser has folded a long sequence of concatenations of string
1560 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
1561 and "JMP_BUF" variables as artificial.
1562 (N_String_Literal): Do not use alloca for very long string literals. Use
1563 xmalloc/free instead. Otherwise the stack might overflow.
1565 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
1568 2007-08-16 Vincent Celier <celier@adacore.com>
1570 * vms_conv.adb (Process_Argument): Ensure that project related options
1571 are not put in the -cargs section when using GNAT COMPILE.
1573 2007-08-16 Robert Dewar <dewar@adacore.com>

1607 2007-08-14 Robert Dewar <dewar@adacore.com>
1608 Ed Schonberg <schonberg@adacore.com>
1610 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
1611 Suppress unmodified in-out parameter warning in some cases
1612 This patch is a also fairly significant change to the way suppressible
1615 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
1616 needed for access to concurrent record types generated by the expander.
1617 (Generate_Range_Check): When generating a temporary to capture the
1618 value of a conversion that requires a range check, set the type of the
1619 temporary before rewriting the node, so that the type is always
1620 properly placed for back-end use.
1621 (Apply_Float_Conversion_Check): Handle case where the conversion is
1623 (Get_Discriminal): Code reformatting. Climb the scope stack looking
1624 for a protected type in order to examine its discriminants.

1627 Gary Dismukes <dismukes@adacore.com>
1628 Ed Schonberg <schonberg@adacore.com>
1629 Thomas Quinot <quinot@adacore.com>
1631 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,

1633 tests optimized out.
1635 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
1636 (Get_Allocator_Final_List): For the case of an anonymous access type
1637 that has a specified Associated_Final_Chain, do not go up to the
1639 (Expand_N_Type_Conversion): Test for the case of renamings of access
1640 parameters when deciding whether to apply a run-time accessibility
1642 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
1643 aggregate code before allocator, and ahead of declaration for
1644 temporary, to prevent access before elaboration when the allocator is
1645 an actual for an access parameter.
1646 (Expand_N_Type_Conversion): On an access type conversion involving an
1647 access parameter, do not apply an accessibility check when the
1648 operand's original node was an attribute other than 'Access. We now
1649 create access conversions for the expansion of 'Unchecked_Access and
1650 'Unrestricted_Access in certain cases and clearly accessibility should
1651 not be checked for those.
1653 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
1654 includes a type conversion of a packed component that has been expanded,
1655 recover the original expression for the object, and use this expression
1656 in the post-call assignment statement, so that the assignment is made
1657 to the object and not to a back-end temporary.
1658 (Freeze_Subprogram): In case of primitives of tagged types not defined
1659 at the library level force generation of code to register the primitive
1660 in the dispatch table. In addition some code reorganization has been
1661 done to leave the implementation clear.
1662 (Expand_Call): When expanding an inherited implicit conversion,
1663 preserve the type of the inherited function after the intrinsic
1664 operation has been expanded.
1666 * exp_ch2.ads, exp_ch2.adb
1667 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
1668 of an entry formal appearing in an assignment statement does not assign
1670 (Expand_Current_Value): Instead of calling a routine to determine
1671 whether the prefix of an attribute reference should be optimized or
1672 not, prevent the optimization of such prefixes all together.
1674 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
1675 component whose prefix is known to be of an access type is an implicit
1676 dereference and does not assign to the prefix.
1678 2007-08-14 Ed Schonberg <schonberg@adacore.com>
1679 Robert Dewar <dewar@adacore.com>
1681 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
1682 itype is visited, make an entry into table to link associated node and
1684 Add comments and correct harmless error in Build_NCT_Hash_Tables
1685 (Array_Aggr_Subtype): Associate each itype created for an index type to
1686 the corresponding range construct, and not to the aggregate itself. to
1687 maintain a one-to-one correspondence between itype and its associated
1688 node, to prevent errors when complex expression is copied.
1689 Fix mishandling of multiple levels of parens
1691 * sem_aggr.adb: Create a limited view of an incomplete type, to make
1692 treatment of limited views uniform for all visible declarations in a
1693 limited_withed package.
1694 (New_Copy_Tree): If hash table is being used and itype is visited,
1695 make an entry into table to link associated node and new itype.
1696 (Resolve_Record_Aggregate): Do not add an others box association for a
1697 discriminated record component that has only discriminants, when there
1698 is a box association for the component itself.
1700 * par-ch4.adb: Fix mishandling of multiple levels of parens
1702 2007-08-14 Robert Dewar <dewar@adacore.com>
1704 * comperr.adb: Fix problem with suppressing warning messages from gigi

1707 errout.adb (Write_Eol): Remove trailing spaces before writing the line
1708 (Write_Eol_Keep_Blanks): New procedure to write a line, including
1709 possible trailing spaces.

1735 Javier Miranda <miranda@adacore.com>
1736 Gary Dismukes <dismukes@adacore.com>
1738 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
1739 to make treatment of limited views uniform for all visible declarations
1740 in a limited_withed package.
1741 Improve warnings for in out parameters
1742 (Set_Related_Interaface/Related_Interface): Allow the use of this
1743 attribute with constants.
1744 (Write_Field26_Name): Handle attribute Related_Interface in constants.
1745 Warn on duplicate pragma Preelaborable_Initialialization
1747 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
1748 generation of a freezing node to ensure proper management of null
1749 excluding access types in the backend.
1750 (Create_Extra_Formals): Test base type of the formal when checking for
1751 the need to add an extra accessibility-level formal. Pass the entity E
1752 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
1753 originally being done in a couple of cases), to ensure that the
1754 Extra_Formals list gets set on the entity E when the first entity is
1756 (Conforming_Types): Add missing calls to Base_Type to the code that
1757 handles anonymous access types. This is required to handle the
1758 general case because Process_Formals builds internal subtype entities
1759 to handle null-excluding access types.
1760 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
1761 functions that need it, even when not marked Requires_Overriding.
1762 Improve warnings for in out parameters
1763 (Analyze_Function_Return): Warn for disallowed null return
1764 Warn on return from procedure with unset out parameter
1765 Ensure consistent use of # in error messages
1766 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
1767 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
1768 the implicit conversion of the expression done for anonymous access
1769 types. This is required to generate the code of the null excluding
1770 check (if required).
1772 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
1773 A formal parameter is never publicly referenceable outside of its body.
1774 (Check_References): For an unreferenced formal parameter in an accept
1775 statement, use the same warning circuitry as for subprogram formal
1777 (Warn_On_Unreferenced_Entity): New subprogram, taken from
1778 Output_Unreferenced_Messages, containing the part of that routine that
1779 is now reused for entry formals as described above.
1780 (Goto_Spec_Entity): New function
1781 (Check_References): Do not give IN OUT warning for dispatching operation
1782 Improve warnings for in out parameters
1783 (Test_Ref): Check that the entity is not undefinite before calling
1784 Scope_Within, in order to avoid infinite loops.
1785 Warn on return from procedure with unset out parameter
1786 Improved warnings for unused variables
1788 2007-08-14 Robert Dewar <dewar@adacore.com>
1789 Javier Miranda <miranda@adacore.com>
1790 Gary Dismukes <dismukes@adacore.com>
1792 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
1793 (Expand_N_Attribute_Reference): Further unify the handling of the
1794 three forms of access attributes, using common code now for all three
1795 cases. Add a test for the case of applying an access attribute to
1796 an explicit dereference when the context is an access-to-interface
1797 type. In that case we need to apply the conversion to the prefix
1798 of the explicit dereference rather than the prefix of the attribute.
1799 (Attribute_Version, UET_Address): Set entity as internal to ensure
1800 proper dg output of implicit importation.
1801 (Expand_Access_To_Type): Removed.
1802 (Expand_N_Attribute_Reference): Merge the code from the three cases
1803 of access attributes, since the processing is largely identical for
1804 these cases. The substantive fix here is to process the case of a
1805 type name prefix (current instance case) before handling the case
1806 of interface prefixes.
1808 2007-08-14 Thomas Quinot <quinot@adacore.com>
1809 Ed Schonberg <schonberg@adacore.com>
1810 Javier Miranda <miranda@adacore.com>
1811 Robert Dewar <dewar@adacore.com>
1813 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
1814 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
1815 type that is an anonymous access to controlled object, establish
1816 an associated finalization chain to avoid corrupting the global
1817 finalization list when a dynamically allocated object designated
1818 by such a component is deallocated.
1819 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
1820 functions that need it, even when not marked Requires_Overriding.
1821 (Initialize_Tag): Replace call to has_discriminants by call to
1822 Is_Variable_Size_Record in the circuitry that handles the
1823 initialization of secondary tags.
1824 (Is_Variable_Size_Record): New implementation.
1825 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
1826 Suppress_Initialization pragma for a derived type.
1827 (Is_Variable_Size_Record): New subprogram.
1828 (Build_Offset_To_Top_Functions): New implementation that simplifies the
1829 initial version of this routine and also fixes problems causing
1830 incomplete initialization of the table of interfaces.
1831 (Build_Init_Procedure): Improve the generation of code to initialize the
1832 the tag components of secondary dispatch tables.
1833 (Init_Secondary_Tags): New implementation that simplifies the previous
1834 version of this routine.
1835 (Make_DT): Add parameter to indicate when type has been frozen by an
1836 object declaration, for diagnostic purposes.
1837 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
1838 diagnose attemps to freeze a subprogram when some untagged type of its
1839 profile is a private type whose full view has not been analyzed yet.
1840 (Freeze_Array_Type): Generate init proc for packed array if either
1841 Initialize or Normalize_Scalars is set.
1842 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
1843 constructing the new profile, copy the null_exclusion indicator for each
1844 parameter, to ensure full conformance of the new body with the spec.
1846 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
1847 Create wrappers for constructor functions that need it, even when not
1848 marked Requires_Overriding.
1849 (Covers): Handle properly designated types of anonymous access types,
1850 whose non-limited views are themselves incomplete types.
1851 (Add_Entry): Use an entity to store the abstract operation which hides
1853 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
1854 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
1855 initialization aggregate.
1856 (Function_Interp_May_Be_Hidden): Rename to
1857 Function_Interp_Has_Abstract_Op.
1858 (Has_Compatible_Type): Remove machinery that skips interpretations if
1859 they are labeled as potentially hidden by an abstract operator.
1860 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
1861 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
1862 (Write_Overloads): Output the abstract operator if present.
1863 (Add_Entry): Before inserting a new entry into the interpretation table
1864 for a node, determine whether the entry will be disabled by an abstract
1866 (Binary_Op_Interp_May_Be_Hidden): New routine.
1867 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
1869 (Function_Interp_May_Be_Hidden): New routine.
1870 (Has_Compatible_Type): Do not consider interpretations hidden by
1871 abstract operators when trying to determine whether two types are
1873 (Has_Hidden_Interp): New routine.
1874 (Set_May_Be_Hidden_Interp): New routine.
1875 (Write_Overloads): Write the status of flag May_Be_Hidden.
1877 2007-08-14 Ed Schonberg <schonberg@adacore.com>
1878 Javier Miranda <miranda@adacore.com>
1880 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
1881 types declared in the declarative part of a nested package body or in
1882 the proper body of a stub.
1883 (Set_All_DT_Position): Add missing check to avoid wrong assignation
1884 of the same dispatch table slot to renamed primitives.
1885 (Make_Select_Specific_Data_Table): Handle private types.
1886 (Tagged_Kind): Handle private types.
1887 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
1888 output of implicit importation and exportation.
1889 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
1890 first formal of the thunk is always associated with the controlling
1891 type. In addition perform the following code cleanup: remove formal
1892 Thunk_Alias which is no longer required, cleanup evaluation of the
1893 the controlling type, and update the documentation.
1894 Replace occurrence of Default_Prim_Op_Count by
1895 Max_Predef_Prims. Addition of compile-time check to verify
1896 that the value of Max_Predef_Prims is correct.
1897 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
1898 (Make_DT): Add parameter to indicate when type has been frozen by an
1899 object declaration, for diagnostic purposes.
1900 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
1901 construction of statically allocated dispatch tables.
1902 (Make_DT): In case of library-level tagged types export the declaration
1903 of the primary tag. Remove generation of tags (now done by Make_Tags).
1904 Additional modifications to handle non-static generation of dispatch
1905 tables. Take care of building tables for asynchronous interface types
1906 (Make_Tags): New subprogram that generates the entities associated with
1907 the primary and secondary tags of Typ and fills the contents of Access_
1908 Disp_Table. In case of library-level tagged types imports the forward
1909 declaration of the primary tag that will be declared later by Make_DT.
1910 (Expand_Interface_Conversion): In case of access types to interfaces
1911 replace an itype declaration by an explicit type declaration to avoid
1912 problems associated with the scope of such itype in transient blocks.
1914 2007-08-14 Robert Dewar <dewar@adacore.com>
1915 Ed Schonberg <schonberg@adacore.com>
1916 Javier Miranda <miranda@adacore.com>
1918 * exp_util.ads, exp_util.adb:
1919 This patch replaces a number of occurrences of explicit tests for N_Null
1920 with calls to Known_Null. This improves tracking of null values, since
1921 Known_Null also catches null constants, and variables currently known to
1922 be null, so we get better tracking.
1923 (Ensure_Defined): create an itype reference only in the scope of the
1925 (Side_Effect_Free): A selected component of an access type that
1926 denotes a component with a rep clause must be treated as not
1927 side-effect free, because if it is part of a linked structure its
1928 value may be affected by a renaming.
1929 (Expand_Subtype_From_Expr): For limited objects initialized with build
1930 in place function calls, do nothing; otherwise we prematurely introduce
1931 an N_Reference node in the expression initializing the object, which
1932 breaks the circuitry that detects and adds the additional arguments to
1933 the called function. Bug found working in the new patch for statically
1934 allocated dispatch tables.
1935 (Is_Library_Level_Tagged_Type): New subprogram.
1936 (Remove_Side_Effects): If the expression of an elementary type is an
1937 operator treat as a function call.
1938 (Make_Literal_Range): If the index type of the array is not integer, use
1939 attributes properly to compute the constraint on the resulting aggregate
1942 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
1943 class-wide type whose base type is an incomplete private type, leave
1944 class-wide type unfrozen so that freeze nodes can be generated
1945 properly at a later point.
1946 (Freeze_Entity, array case): Handle case of pragma Pack and component
1947 size attributre clause for same array.
1949 2007-08-14 Vincent Celier <celier@adacore.com>
1951 * prj.ads, prj.adb: Update Project Manager to new attribute names for
1953 Allow all valid declarations in configuration project files
1954 (Reset): Initialize all tables and hash tables in the project tree data
1955 Major update of the Project Manager and of the project aware tools,
1956 including gprmake, so that the same sources in the GNAT repository
1957 can be used by gprbuild.

2596 operations in Derive_Subprograms.
2597 (Collect_Previous_Instances): new procedure within of
2598 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
2599 unit being loaded, to ensure that the generation of global symbols is
2600 consistent in different compilation modes.
2601 (Is_Tagged_Ancestor): New function testing the ancestor relation that
2602 takes progenitor types into account.
2603 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
2604 traversing over the primitives of the formal and actual types to locate
2605 any abstract subprograms of the actual type that correspond to a
2606 nonabstract subprogram of the formal type's ancestor type(s), and issue
2607 an error if such is found.
2608 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
2609 Instantiate_Package_Body, Instantiate_Subprogram_Body):
2610 Remove bogus guard around calls to Inherit_Context.

2623 an access_to_constant type.
2624 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
2625 type, the candidate operations are found in the scope of declaration of
2626 the type, because the type has no primitive subprograms.
2627 (Analyze_Selected_Component): If prefix is class-wide, and root type is
2628 a private extension, only examine visible components before trying to
2629 analyze as a prefixed call.
2630 Change Entity_List to Type_To_Use, for better readability.
2631 (Has_Fixed_Op): Use base type when checking whether the type of an
2632 operator has a user-defined multiplication/division

2642 current visibility context only).
2643 (Missing_Read_Write_Attributes): A stream attribute is missing for the
2644 purpose of enforcing E.2.2(8) only if it is not available at any place.
2645 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
2646 when checking the legality of an extension aggregate in a preelaborable
2647 package. Treat the literal null as a valid default expression in a
2648 component declaration for a type with preelaborable initialization.
2649 A limited interface is a legal progenitor for the designated type of a
2650 remote access to class-wide type.

2664 views that are themselves incomplete types.
2665 Handle interfaces visible through limited-with clauses.
2666 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
2667 subprogram generic actual for which we have generated a renaming.

2680 when the type of the interpretation matches that of the context.
2681 (Resolve): When looping through all possible interpretations of a node,
2682 do not consider those that are hidden by abstract operators.
2683 (Resolve_Actuals): When verifying that an access to class-wide object
2684 is an actual for a controlling formal, ignore anonymous access to
2685 subprograms whose return type is an access to class_wide type.
2686 (Resolve_Slice): If the prefix of the slice is a selected component
2687 whose type depends on discriminants, build its actual subtype before
2688 applying range checks on the bounds of the slice.

2711 elabration statements, register the package with the name server
2712 at the beginning, not at the end, of the elaboration statements so

2718 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
2719 values to compute the number of seconds since the Unix Epoc in order to
2720 account for Daylight Savings Time. Perform special processing for dates
2721 that are earlier than the Unix Epoc to obtain a negative number.

2924 Add s-osinte-vxworks-kernel.adb to the target pairs of the
2925 kernel run-time lib for VxWorks 6, which would provide a different
2926 implementation for Task_Cont and Task_Stop than the VxWorks 5 version.
2927 x86-solaris section (EH_MECHANISM): Set to -gcc, as this port is now
2928 running ZCX by default.

3808 (Check_System_Restrictions_Used): New procedure
3810 * s-stalib.adb: Remove with of System.Restrictions. No longer needed
3811 since we only with this unit in the binder file if it is used elsewhere
3814 2007-06-06 Vincent Celier <celier@adacore.com>
3816 * bindusg.adb: Add line for @<response file>
3817 Add lines for new switches -R and -Z
3819 * gnatbind.adb (Gnatbind): Do not include sources from the GNAT
3820 hierarchy in the list of files of the closure when -R is used
3821 (Gnatbind): Accept arguments starting with '@' to indicate response
3822 files and take the arguments from the response files.
3823 If List_Closure is set, display the referenced files

3826 Robert Dewar <dewar@adacore.com>
3827 Ed Schonberg <schonberg@adacore.com>
3829 * checks.ads, checks.adb (Apply_Address_Clause_Check): Handle case in
3830 which the address-clause is applied to in-mode actuals (allowed by
3832 (Apply_Discriminant_Check): Do not generate a check if the type is
3833 constrained by a current instance.
3834 (Activate_Division_Check): New procedure
3835 (Activate_Overflow_Check): New procedure
3836 (Activate_Range_Check): New procedure
3837 Call these new Activate procedures instead of setting flags directly
3838 (Apply_Array_Size_Check): Removed, no longer needed.
3839 Code clean up: remove obsolete code related to GCC 2.
3840 (Get_E_Length): Protect against bomb in case scope is standard
3841 (Selected_Range_Checks): If the node to be checked is a conversion to
3842 an unconstrained array type, and the expression is a slice, use the
3843 bounds of the slice to construct the required constraint checks.
3844 Improve NOT NULL error messages
3845 (Apply_Constraint_Check): If the context is a null-excluding access
3846 type, diagnose properly the literal null.
3848 2007-06-06 Pascal Obry <obry@adacore.com>
3850 * clean.adb (Clean_Archive): Use untouched casing for the archive name
3851 and the corresponding .deps file.
3852 (Clean_Interface_Copy_Directory): Use untouched casing for the library
3853 src directory. Minor code-clean-up. Use untouched casing for files
3854 read into the library src dir.
3855 (Clean_Library_Directory): Idem.
3856 (Parse_Cmd_Line): Accept new switch -aP

3861 Eric Botcazou <ebotcazou@adacore.com>
3862 Arnaud Charlet <charlet@adacore.com>
3864 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
3865 applicable to types that have the With_Type flag set. Returns the
3866 non-limited view of the type, if available, otherwise the type itself.
3867 For class-wide types, there is no direct link in the tree, so we have
3868 to retrieve the class-wide type of the non-limited view of the Etype.
3869 New attributes Static_Initialization and Static_Elaboration_Desired.
3870 Remove the pragma Thread_Body, and the associated flag
3871 Is_Thread_Body in entities, and all related code.
3872 (Suppress_Value_Tracking_On_Call): New flag
3873 E_Exception has Esize and Alignment fields
3874 (Universal_Aliasing): New function.
3875 (Set_Universal_Aliasing): New procedure.
3876 (Write_Entity_Flags): Deal with Universal_Aliasing flag.
3877 (Check_Nested_Access): New procedure.
3878 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
3879 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
3880 (Related_Interface): New attribute. Present in dispatch table pointer
3881 components of records. Set to point to the entity of the corresponding
3883 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
3884 (Original_Access_Type): Remove, not needed.
3885 (Root_Type): Handle properly subtypes of class-wide-types.
3888 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
3889 class-wide types visible through limited-with clauses.
3890 (Try_Primitive_Operation): When examining all primitive operations of a
3891 tagged type, do not consider subprograms labeled as hidden unless they
3892 belong to a private generic type with a tagged parent.
3893 (Try_Object_Operation): Extensive rewriting, to handle properly various
3894 overloading cases, when several ancestors may have class-wide operations
3895 that are possible candidates, and when the overloaded functions return
3896 array types and have defaulted parameters so that the call may be
3897 interpreted as an indexing.
3898 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
3899 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
3900 successive actuals before analyzing the call itself.
3901 (Try_Primitive_Operation): A primitive operation is compatible with the
3902 prefix if the prefix has a synchronized type and the type of the formal
3903 is its corresponding record, as can be the case when the primitive
3904 operation is declared outside of the body of the type.
3905 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
3906 perform homonym traversal, looking for class-wide operation matches
3907 (formerly done in statements of Try_Class_Wide_Operation). Matches on
3908 access parameters are now restricted to anonymous access types.
3909 (Mark_Allocator): An allocator with a discriminant association parent is
3911 (Try_One_Prefix_Interpretation): If the type of the object is
3912 incomplete, as can be happen when it is a limited view obtained through
3913 a limited_with_clause, the selected component is not part of a prefixed
3915 (Complete_Object_Operation): Diagnose properly an object that is not
3916 aliased when the corresponding controlling formal is an access
3918 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
3919 ambiguous calls in prefixed notation, where two primitives differ only
3920 in that the controlling argument of one is an access parameter.
3922 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
3923 whether a function that returns an unconstrained type can be inlined.
3924 (Process_Formals): Diagnose properly the illegal use of an incomplete
3925 type in the profile of an access_to_subprogram declaration.
3926 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
3927 operations are attached to the corresponding record.
3928 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
3929 When processing a primitive of a concurrent type which implements an
3930 interface change the type of all controlling formals to that of the
3931 corresponding record type.
3932 (Check_Synchronized_Overriding): Relax the conditional logic when trying
3933 to determine the tagged type to which a primitive belongs.
3934 (Check_Conventions): Capture condition to ignore a primitive operation
3935 (which is shared between the loop in Check_Conventions and the one in
3936 Check_Convention) in a new local function Skip_Check.
3937 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
3938 confusion with Check_Conventions' own Prim_Op local variable.
3939 (Create_Extra_Formals): Test for a tagged result type rather than a
3940 controlling result when determining whether to add a BIP_Alloc_Form
3941 formal and a BIP_Final_List formal to the function.
3942 (Check_Conformance); For parameters that are anonymous access types,
3943 subtype conformance requires that the not null and the constant
3944 indicators must match
3945 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
3946 to retrieve the appropriate type when processing a concurrent type
3947 declared within a generic. Minor comment reformatting. Change invocation
3948 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
3950 (Analyze_Subprogram_Body): If the return type of a function is an
3951 anonymous access to the limited view of a class-wide type, and the
3952 non-limited view of the type is available, update the type of the
3953 function so that code can be generated.
3954 (Process_Formals): In case of access-subtype itype whose designated
3955 type is also an itype (situation that happens now with access to
3956 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
3957 attribute to avoid backend problems.
3958 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
3959 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
3960 anonymous types' designated types are same before testing
3961 Subtypes_Statically_Match.
3962 (Create_Extra_Formals): Test for a named access parameter that is a
3963 controlling formal as an additional condition for adding an
3964 accessibility level formal. This can occur in the subp type created for
3965 dispatching calls in Expand_Dispatching_Call, and allows calling
3966 Create_Extra_Formals from that procedure rather than special-casing the
3967 extra formals there.
3968 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
3969 when the function has a controlling result.
3970 (Check_Returns): Add much more knowledge of the optimization of local
3971 raise statements to gotos, to retain proper warnings in this case.
3972 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
3973 nodes when looking for last statement.
3975 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
3976 class-wide types visible through limited with clauses.
3977 (Add_One_Interp): If the operands are anonymous access types, the
3978 predefined operator on universal_access is immediately visibles
3979 (Find_Unique_Type): Handle anonymous access to subprogram types just as
3980 other anonymous access types.
3981 (Disambiguate): Take into account CIL convention.
3982 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
3984 2007-06-06 Robert Dewar <dewar@adacore.com>
3986 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
3987 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
3988 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
3989 Fix lower bound of tables.
3992 * nlists.adb: Ditto.
3993 (Prev_Node, Next_Node): Change index type to Int so that it properly
3994 covers the range First_Node_Id - 1 up.

3999 Hristian Kirtchev <kirtchev@adacore.com>
4001 * exp_aggr.ads, exp_aggr.adb:
4002 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
4003 in extension aggregates.
4004 (Flatten): Other conditions being met, an aggregate is static if the
4005 low bound given by component associations is different from the low
4006 bound of the base index type.
4007 (Packed_Array_Aggregate_Handled): If the component type is itself a
4008 packed array or record, the front-end must expand into assignments.
4009 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
4010 Init_Pr, instead of Ancestor_Is_Expression.
4011 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
4012 coextension chain root, either generate a list controller or use the
4013 already existing one.
4014 (Static_Array_Aggregate): New procedure to construct a positional
4015 aggregate that can be handled by the backend, when all bounds and
4016 components are compile-time known constants.
4017 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
4018 types covering interface types into assignments.
4019 (Replace_Type): move to Build_Record_Aggr_Code.
4020 (Expand_Record_Aggr_Code): if the target of the aggregate is an
4021 interface type, convert to the definite type of the aggregate itself,
4022 so that needed components are visible.
4023 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
4024 components and the context is an extended return statement do not
4025 create a transient block for it, to prevent premature finalization
4026 before the return is executed.
4027 (Gen_Assign): Do not generate a call to deep adjust routine if the
4028 component type is itself an array of controlled (sub)-components
4029 initialized with an inner aggregate.
4030 (Component_Check): New name for Static_Check. This name is now more
4031 appropriate, and documentation is added which was missing.
4032 (Component_Check): Add test for bit aligned component value
4033 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
4034 Tagged_Comps, name is more appropriate given added function below.
4035 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
4037 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
4038 Javier Miranda <miranda@adacore.com>
4039 Robert Dewar <dewar@adacore.com>
4041 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
4042 Terminated: Add unchecked type conversion from System.Address to
4043 System.Tasking.Task_Id when calling the predefined primitive
4045 Disable new Ada 05 accessibility check for JVM.NET targets, which
4046 cannot be implemented in a practical way.
4047 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
4048 the sources always references the tag of the actual object. Therefore,
4049 if 'Tag is applied in the sources to class-wide interface objects we
4050 generate code that displaces "this" to reference the base of the object.
4051 (Expand_N_Attribute_Reference, case Size): Return specified size if
4053 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
4054 has code that displaces the pointer of the object to manage interface
4055 types. However this code must not be executed when the prefix is a
4056 subprogram. This bug caused the wrong expansion of the internally
4057 generated assignment that fills the dispatch table when the primitive
4058 is a function returning a class-wide interface type.
4059 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
4060 Set_Attribute_Name for Name_Unaligned_Valid.
4062 2007-06-06 Ed Schonberg <schonberg@adacore.com>
4063 Gary Dismukes <dismukes@adacore.com>
4065 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
4066 If the initialization is the equivalent aggregate of the initialization
4067 procedure of the type, do not remove it.
4068 (Expand_N_Attribute_Definition_Clause): Exclude access variables
4069 initialized to null from having their expression reset to empty and
4070 note this exception in the comment.

4074 Ed Schonberg <schonberg@adacore.com>
4075 Gary Dismukes <dismukes@adacore.com>
4077 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
4078 Add "with" and "use" clauses for Sem_Attr.
4079 (Expand_Current_Value): Do not replace occurences of attribute
4080 references where the prefix must be a simple name.
4082 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
4083 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
4084 Attribute_Requires_Simple_Name_Prefix.
4085 (Name_Modifies_Prefix): Body of new function.
4086 (Requires_Simple_Name_Prefix): Body of new function.
4087 (Resolve_Attribute, case Access): Improve error message for case of
4088 mismatched conventions.
4089 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
4091 (Analyze_Attribute, case 'Access): If the type of the prefix is a
4092 constrained subtype for a nominal unconstrained type, use its base type
4093 to check for conformance with the context.
4094 (Resolve_Attribute): Remove test of the access type being associated
4095 with a return statement from condition for performing accessibility
4096 checks on access attributes, since this case is now captured by
4097 Is_Local_Anonymous_Access.
4098 (Analyze_Access_Attribute): Set Address_Taken on entity
4099 (Analyze_Attribute, case Address): Set Address_Taken on entity
4100 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
4101 validating an access attribute whose prefix is a current instance.
4102 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
4103 applied to dispatching operations, if freezing is required then we set
4104 the attribute Has_Delayed_Freeze in the prefix's entity.
4105 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
4106 current scope if access of local subprogram taken
4107 (Analyze_Access_Attribute): Check legality of self-reference even if the
4108 expression comes from source, as when a single component association in
4109 an aggregate has a box association.
4110 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
4111 the prefix if it is a protected operation and the attribute is
4112 Unrestricted_Access.
4113 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
4114 reference to the base type of the context, to force a constraint check
4115 when the context is an access subtype with an explicit constraint.
4116 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
4117 node is rewritten as an interface conversion. leave unanalyzed after
4118 resolution, to ensure that type checking against the context will take

4122 Javier Miranda <miranda@adacore.com>
4123 Robert Dewar <dewar@adacore.com>
4125 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
4126 wrapper when the full view of the controlling type of an inherited
4127 function that dispatches on result implements interfaces.
4128 (Expand_N_Object_Declaration): In cases where the type of the
4129 declaration is anonymous access, create finalization list for it.
4130 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
4131 if the object has no explicit initialization, to match description of
4132 functionality of pragam Persistent_BSS.
4133 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
4134 new function to build static aggregates, to replace initialization call
4135 when static initialization is desired.
4136 (Freeze_Type): Generate a list controller for an access type whenever
4137 its designated type has controlled anonymous access discriminants.
4138 (Build_Equivalent_Aggregate): New procedure to compute a static
4139 aggregate to be used as default initialization for composite types,
4140 instead of a generating a call to the initialization procedure for the
4142 (Build_Initialization_Call): When available, replace a call to the
4143 initialization procedure with a copy of the equivalent static aggregate
4145 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
4146 declarations for objects of a class-wide interface type, rather than
4147 just identifiers, to prevent visibility problems.
4148 (Expand_N_Object_Declaration): When expanding the declaration for an
4149 object of a class-wide interface type, preserve the homonym chain of
4150 the original entity before exchanging it with that of the generated
4151 renaming declaration.
4152 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
4153 active, because there is no way to handle the exception.
4154 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
4155 to do a minimum decoration of the Access_Disp_Table list.
4156 (Expand_Record_Controller): Avoid the addition of the controller between
4157 the component containing the tag of a secondary dispatch table and its
4158 adjacent component that stores the offset to the base of the object.
4159 This latter component is only generated when the parent type has
4160 discriminants ---documented in Add_Interface_Tag_Components).
4161 (Apply_Array_Size_Check): Removed, no longer needed.
4162 (Expand_N_Full_Type_Declaration): If the type has anonymous access
4163 components, create a Master_Entity for it only if it contains tasks.
4164 (Build_Init_Procedure): Suppress the tag assignment compiling under
4166 (Freeze_Record_Type): Remove code associated with creation of dispatch
4168 (Init_Secondary_Tags): Update type of actuals when generating calls to
4169 Ada.Tags.Set_Offset_To_Top
4170 (Stream_Operation_OK): Disable use of streams compiling under no
4172 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
4173 if Has_Init_Expression set.
4174 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
4175 Register_Primitive, which provides the same functionality.
4176 (Requires_Init_Proc): Return false in case of interface types.
4177 (Add_Secondary_Tables): Use the new attribute Related_Interface to
4179 (Predefined_Primitive_Freeze): Do not assume that an internal entity
4180 is always associated with a predefined primitive because the internal
4181 entities associated with interface types are not predefined primitives.
4182 Therefore, the call to Is_Internal is replaced by a call to the
4183 function Is_Predefined_Dispatching_Operation.
4184 (Make_Eq_If): When generating the list of comparisons for the
4185 components of a given variant, omit the controller component that is
4186 present if the variant has controlled components.
4188 2007-06-06 Javier Miranda <miranda@adacore.com>
4189 Hristian Kirtchev <kirtchev@adacore.com>
4190 Bob Duff <duff@adacore.com>
4192 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
4193 handle the creation of finalization lists and calls for nested
4194 coextensions when the root of the chains is part of a return statement.
4195 (Inside_A_Return_Statement): New function inside Complete_Coextension_
4197 (Expand_Record_Equality): Skip components that are interface types.
4198 (Displace_Allocator_Pointer): Add missing support for interface subtypes
4199 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
4200 with Rewrite_Coextension. Change the condition for detecting coextension
4202 (Is_Local_Access_Discriminant): Removed.
4203 (Rewrite_Coextension): New routine which rewrites a static coextension
4204 as a temporary and uses its unrestricted access in the construction of
4206 (Complete_Coextension_Finalization): New routine. Generate finalization
4207 attachment calls to all delayed coextensions.
4208 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
4209 the allocator is not a coextension itself and has delayed coextensions.
4210 If the current allocator is controlled, but also a coextension, delay
4211 the generation of the finalization attachment call.
4212 Rename local variable "Node" to "Nod" in order to avoid confusion with
4214 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
4215 limited types that are not inherently limited. Such an allocator is
4216 illegal, but is generated by the expander for a return statement, to
4217 copy the result onto the secondary stack. This is the only case where a
4218 limited object can be copied. Generate code to displace the pointer
4219 to the object if the qualified expression is a class-wide interface
4220 object. Such displacement was missing and hence the copy of the object
4222 (Apply_Accessibility_Check): Handle allocated objects initialized in
4224 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
4225 and Expand_Allocator_Expression. Allocating class-wide interface objects
4226 this routine displaces the pointer to the allocated object to reference
4227 the component referencing the corresponding secondary dispatch table.
4228 Expand_Allocator_Expression): Add missing support to allocate class-wide
4229 interface objects initialized with a qualified expression.
4230 (Get_Allocator_Final_List): Test for an anonymous access type that is a
4231 function result type, and use the finalization list associated with the
4232 function scope in that case (such an anonymous type should not be
4233 treated like an access parameter's type).

4236 Gary Dismukes <dismukes@adacore.com>
4237 Javier Miranda <miranda@adacore.com>
4239 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
4240 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
4241 required exception handler.
4242 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
4243 properly the case of a function whose return type is a limited
4244 class-wide interface type. Modify the code of the accessibility
4245 check to handle class-wide interface objects. In this case we need to
4246 displace "this" to reference the primary dispatch table to get access
4247 to the TSD of the object (to evaluate its accessibility level).
4248 (Expand_N_Extended_Return_Statement): Test for a tagged result type
4249 rather than a controlling result as one of the conditions for
4250 generating tests of the implicit BIP_Alloc_Form formal. The
4251 initialization assignment is also handled according to whether the
4252 result is tagged instead of controlling.
4253 In the case where the init assignment is inserted in the "then" part of
4254 the allocation conditional, rewrite the target to be a dereference of
4255 the implicit BIP_Object_Access formal.
4256 If the returned value is unconstrained and created on the secondary
4257 stack, mark the enclosing block and function so that the secondary
4258 stack is not reclaimed on return.
4259 Treat returns from functions with controlling results similarly to
4260 returns from functions with unconstrained result subtypes.
4261 If the object returned is unconstrained, and an allocator must be
4262 created for it, analyze the allocator once the block for the extended
4263 return is installed, to ensure that finalizable components
4264 of the expression use the proper finalization list. Guard the call to
4265 Move_Final_List with a check that there is something to finalize.
4266 (Make_Tag_Ctrl_Assignment): Use "old" handling
4267 of controlled type assignment for virtual machines, since new code uses
4268 unsupported features (such as direct access to bytes in memory).
4270 2007-06-06 Gary Dismukes <dismukes@adacore.com>
4271 Ed Schonberg <schonberg@adacore.com>
4273 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
4274 accessibility actual, check for the case of an aliased object that has
4275 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
4276 we fall into processing for the attribute rather than the name of the
4278 (Expand_Inline_Call): If an actual is a literal, and the corresponding
4279 formal has its address taken in the body, create a temporary to capture
4280 value. If the return type is a limited interface, do not treat the
4281 return value as Controlled.
4282 (Is_In_Place_Function): If the return type is a limited interface,
4283 treat as returning in place. The actual returned object may not always
4284 be limited, but the caller has to assume that it is returned in place.
4285 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
4286 context of an allocator, use the correct finalization chain (that is,
4287 the chain belonging to the access type, rather than the chain belonging
4288 to the current scope).
4289 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
4290 result type rather than a controlling result as a precondition for
4291 adding an allocation form actual to a build-in-place call.
4292 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
4293 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
4294 primitive in the dispatch tables. This work is now done by Make_DT when
4296 (Register_Predefined_DT_Entry): Removed.
4297 (Add_Return): If end label is not present, use sloc of last statement
4298 for generated return statement in procedure, for better gdb behavior
4300 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
4301 object address nodes to ensure proper processing by routines like
4303 (Expand_Call): Fix generation of validity check for parameter
4304 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
4305 the allocation form parameter if the result subtype is constrained,
4306 except when the function has a controlling result.
4307 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
4308 rather than Is_Controlled and Has_Controlled_Component, since we want to
4309 include class-wide result types in this treatment. Also test for a
4310 controlling result, since that also requires passing a finalization
4312 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
4313 even when the result subtype is constrained, to handle calls involving
4314 controlling results.
4315 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
4316 is now called even when the result subtype is constrained, to handle
4317 calls involving controlling results.
4318 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
4319 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
4320 now performs the test).
4321 (Make_Build_In_Place_Call_In_Object_Declaration):
4322 Add_Alloc_Form_Actual_* is now called even when the result subtype is
4323 constrained, to handle calls involving controlling results.
4324 (Add_Return): Accomodate rewritten pattern from local raise to goto
4325 transformation, so that we still recognize an transfer statement
4326 and do the right thing here in that case.
4327 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
4328 and end of subprogram code.
4329 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
4330 support for primitives that are functions (without formals) with a
4332 (Inherited_From_Formal): If the actual subtype has not generic parent
4333 type, it is not an actual for a formal derived type, and there is no
4334 operation to inherit from the formal.
4336 2007-06-06 Ed Schonberg <schonberg@adacore.com>
4337 Thomas Quinot <quinot@adacore.com>
4339 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
4340 inserted cleanup code appropriately for GDB use.
4341 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
4342 exception handler for Deep_Adjust or Deep_Finalize.
4343 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
4344 Raise_From_Controlled_Operation is available, use a call to that
4345 subprogram instead of a plain "raise Program_Error" node to raise
4346 Program_Error if an exception is propagated from an Adjust or Finalize
4348 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
4349 appears in the optional statement list of a triggering alternative, the
4350 scope actions can be inserted directly there, and not in the list that
4351 includes the asynchronous select itself.
4353 2007-06-06 Ed Schonberg <schonberg@adacore.com>
4354 Robert Dewar <dewar@adacore.com>

4358 generated exception handler appropriately when debugging generated code.
4359 Deal properly with No_Exception_Propagation restriction mode.
4360 (Expand_N_Abort_Statement): Add an unchecked type conversion from
4361 System.Address to System.Tasking.Task_Id when processing the result of
4362 the predefined primitive _disp_get_task_id.
4363 (Expand_N_Asynchronous_Select): Clarify comment.
4364 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
4365 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
4366 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
4367 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
4368 privals and for generated call to Complete_Entry_Body, for better gdb
4370 (Copy_Result_Type): Utility to construct a parameter and result profile
4371 for protected functions whose return type is an anonymous access to
4373 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
4375 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
4376 point when the local-raise-to-goto transformation has taken place.

4379 Nicolas Setton <setton@adacore.com>
4381 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
4382 functionality when the backend is generating code.
4383 Otherwise any serious error
4384 reported by the backend calling the frontend routine Error_Msg
4385 changes the Compilation_Mode to Check_Semantics, disables the
4386 functionality of this routine and causes the generation of
4387 spureous additional errors.
4389 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
4390 debugging information now generated by the compiler for fat-pointer
4392 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
4394 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.

4401 For a remote call to a function with a classwide return type, apply an
4402 E.4(18) check to the returned value.
4403 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
4404 stream attributes of the designated type of an RACW, as they are not
4405 dispatching primitive operations.
4407 2007-06-06 Geert Bosch <bosch@adacore.com>
4409 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a

4421 attribute compiling package Ada.Tags under No_Run_Time_Mode.
4423 2007-06-06 Javier Miranda <miranda@adacore.com>
4425 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
4426 deallocation of class-wide interface objects.
4427 (Expand_Dispatching_Constructor_Call): Take into account that if the
4428 result of the dispatching constructor is an interface type, the
4429 function returns a class-wide interface type; otherwise the returned
4430 object would be actual. The frontend previously accepted returning
4431 interface types because Expand_Interface_Actuals silently performed
4432 the management of the returned type "as if" it were a class-wide
4434 (Expand_Dispatching_Constructor_Call): Replace call to
4435 Make_DT_Access_Action by direct call to Make_Function_Call.
4437 2007-06-06 Robert Dewar <dewar@adacore.com>
4438 Ed Schonberg <schonberg@adacore.com>
4440 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
4441 compute masking constant, since we now set Esize properly to the
4443 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
4444 to match the alignment.
4445 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
4446 packed arrays of 8 bits or less.
4448 * freeze.adb (Freeze_Entity): When freezing the formals of a
4449 subprogram, freeze the designated type of a parameter of an access type
4450 only if it is an access parameter.
4451 Increase size of C convention enumeration object
4452 (Freeze_Entity, array type case): Make sure Esize value is properly
4453 adjusted for the alignment if it is known.
4454 (Freeze_Entity, array type case): When checking bit packed arrays for
4455 the size being incorrect, check RM_Size, not Esize.
4456 (Freeze_Record_Type): Check for bad discriminated record convention
4457 (In_Exp_Body): Return true if the body is generated for a subprogram
4458 renaming, either an attribute renaming or a renaming as body.
4459 (Check_Itype): If the designated type of an anonymous access component
4460 is a non-protected subprogram type, indicate that it is frozen, to
4461 prevent out-of-scope freeze node at some subsequent call.
4462 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
4463 only if the subprogram is neither imported nor exported, as well as the
4464 NCA descriptor class if the subprogram is exported.

4491 has none of the other categories.
4492 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
4493 to apply Import to an object renaming declaration.
4495 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
4496 from a C++ class should be declared as limited and that it will be
4497 considererd limited.
4498 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class

4524 object of a limited type can be initialized with a call to a function
4525 that returns in place. If the limited type has unknown discriminants,
4526 and the underlying type is a constrained composite type, build an actual
4527 subtype from the function call, as is done for private types.
4528 (Side_Effect_Free): An expression that is the renaming of an object or
4529 whose prefix is the renaming of a object, is not side-effect free
4530 because it may be assigned through the renaming and its value must be
4531 captured in a temporary.
4532 (Has_Controlled_Coextensions): New routine.
4533 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
4534 as is done for other limited types.

4584 Add new warning for renaming of function return objects
4586 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
4587 (Tree_Read): Use size of object instead of type'object_size, since the
4588 latter is incorrect for packed array types.
4589 (Tree_Write): Same fix
4591 * opt.ads: Add new warning for renaming of function return objects
4592 (Generating_Code): New boolean variable used to indicate that the
4593 frontend as finished its work and has called the backend to process
4594 the tree and generate the object file.

4609 Also reject attempt to rename function return object in Ada 83 mode.
4610 (Attribute_Renaming): In case of tagged types, add the body of the
4611 generated function to the freezing actions of the type.
4612 (Find_Type): A protected type is visible right after the reserved word
4613 "is" is encountered in its type declaration. Set the entity and type
4614 rather than emitting an error message.

4641 (Deallocate, Dereference): Send error messages to the proper stream
4642 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
4643 documented. Previous code would send it to the current output file
4644 defined in GNAT.IO, which might not be stdout
4645 (Is_Valid): Adjust comment to mention that a positive reply means that
4646 Header_Of may be used to retrieve the allocation header associated with
4647 the subprogram Storage address argument. Return False early if this
4648 address argument is misaligned.
4650 2007-06-06 Vincent Celier <celier@adacore.com>

4666 Correct error message when invocation of the linker fails
4667 Add explicit size clause for the C imported variables
4668 Object_List_File_Supported and Using_GNU_Linker to emphasize that
4669 we expect char size.
4670 Read target parameters earlier, since this is needed to set
4671 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
4674 2007-06-06 Vincent Celier <celier@adacore.com>
4677 Add 3 spaces before the default project directory when displaying
4678 the project search path.

4704 use the untouched pathname casing.
4705 (Get_Directories): Ensure that the Display_Exec_Directory is using the
4706 proper casing on non case-sensitive platforms like Windows.
4707 (Get_Unit): Accept file names x__... and x~... (where x = a, g, i or s)
4708 on all platforms, as it is not possible to know which one is allowed
4709 before processing the project files.
4710 (Check_Stand_Alone_Library): Check that Library_Reference_Symbol_File is
4711 specified when symbol policy is Direct. Check that when there is a

5245 Do_Division_Check flag explicitly.
5246 (Resolve_Actuals): If the actual is of a synchronized type, and the
5247 formal is of the corresponding record type, this is a call to a
5248 primitive operation of the type, that is declared outside of the type;

6190 required for a conversion between two access-to-unconstrained-array
6192 (Expr_Known_Valid): Validity checks do not apply to discriminants, but

6300 stubbed procedure with a null body, replace the call with a null
6301 statement without using the full inlining machinery, for efficiency
6302 and to avoid invalid values in source file table entries.
6304 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): Add support for
6305 renamings of calls to build-in-place functions.
6307 * rtsfind.adb (RTE_Record_Component_Available): New subprogram that

6329 is an interface; that is, remove the special case for interface types.
6330 (Analyze_Function_Return): Remove error message "return of task objects

6355 build-in-place functions with result type with controlled parts.
6356 Remove no longer used entities.
6358 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no

6395 for all access attributes, because overload resolution should work the
6396 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
6397 causes the error message for the ambiguous "X'Access = Y'Access" and
6398 "X'Unrestricted_Access = Y'Access" and so forth to match.
6399 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
6400 now that anonymous access to protected operations have their own kind.

6414 Check_Anonymous_Access_Components rather than Empty.
6415 (Make_Incomplete_Type_Declaration): Add test for case where the type has
6416 a record extension in deciding whether to create a class-wide type,
6417 rather than just checking Tagged_Present.

6419 to stand-alone object declarations as well as component declarations.
6420 (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to

6446 (Analyze_Subtype_Declaration): For an access subtype declaration, create
6447 an itype reference for the anonymous designated subtype, to prevent

6462 (Compile_Sources): Do nothing, not even check if the source is up to
6463 date, if its project is externally built.
6464 (Compile): When compiling a predefined source, add -gnatpg
6465 as the second switch, after -c.
6466 (Compile_Sources): Allow compilation of Annex J renames without -a
6467 (Is_In_Object_Directory): Check if the ALI file is in the object
6468 even if there is no project extension.

6470 gnatbind if the ALI file effectively exists.
6471 (Initialize): Add the directory where gnatmake is invoked in front of
6472 the path if it is invoked from a bin directory, even without directory
6473 information, so that the correct GNAT tools will be used when spawned
6474 without directory information.

6497 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
6498 when -gnatg is not specified.
6499 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
6500 there is no need to generate always a record_definition_node in case
6501 of synchronized interface types.
6502 (SIS_Entry_Active): Initialize global variable to False
6503 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

6528 (Convert_Aggr_In_Allocator): If the allocator is for an access
6529 discriminant and the type is controlled. do not place on a finalization
6530 list at this point. The proper list will be determined from the

6533 initialize record controller if needed, before the components, to ensure
6534 that they are properly finalized.

6548 same scope level as the allocator's type. The check is guaranteed to
6549 succeed in that case, even when the expression originates from a
6550 parameter of the containing subprogram.
6551 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
6552 under No_Dispatching_Calls restriction. During the semantic analysis
6553 we already notified such violation.

6555 the tag at run-time if the type of the right operand is non
6556 class-wide abstract.

6571 initialize most the TSD components by means of an aggregate.
6572 Modify the declaration of the object containing the TSD
6573 because we now expand code that has a higher level of abstraction.
6574 The TSD has a discriminant containing the Inheritance Depth Level,
6575 value that is used in the membership test but also to fix the size
6576 of the table of ancestors.
6577 (Expand_Interface_Conversion): Insert function body at the closest place
6578 to the conversion expression, to prevent access-before-elaboration

6609 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
6610 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
6611 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
6612 Build_Set_Prim_Op_Address.
6613 (Get_Remotely_Callable): Subprogram removed.
6614 (Init_Predefined_Interface_Primitives): Replace generation of call to
6615 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
6618 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
6619 First (Parameter_Associations ()) with the call to First_Actual that
6620 returns an actual parameter expression for both named and positional

6624 check violation of restriction No_Dispatching_Calls.
6625 (Check_Controlling_Type): A formal of a tagged incomplete type is a

6629 First/Next_Component_Or_Discriminant
6630 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
6631 (Find_Implemented_Interface): Removed. All the calls to this subprogram

6633 provided by the function Has_Abstract_Interfaces.
6634 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
6635 support concurrent types implementing interfaces.
6636 (Find_Implemented_Interface): Removed. All the calls to this subprogram

6638 provided by the function Has_Abstract_Interfaces.
6639 (Remove_Side_Effects): replace Controlled_Type by
6640 CW_Or_Controlled_Type whenever the issue is related to
6641 using or not the secondary stack.
6643 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
6644 P_Interface_Type_Definition to fulfill the new interface (the formal
6645 Is_Synchronized is no longer required).

6648 Update dependencies.
6650 * exp_atag.ads, exp_atag.adb: New file

6653 Bob Duff <duff@adacore.com>
6654 Cyrille Comar <comar@adacore.com>
6656 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
6657 anonymous, use finalization list of enclosing dynamic scope.
6658 (Expand_N_Package_Declaration): For a library package declaration
6659 without a corresponding body, generate RACW subprogram bodies in the
6660 spec (just as we do for the task activation call).
6661 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
6662 Is_Abstract_Type. Make sure these are called only when appropriate.
6663 Remove all code for DSP option

6670 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
6671 parameter. If it is set to true, return a result capped according to
6672 the global upper bound for the index of an entry family.

6674 (Build_Find_Body_Index): Adjust for above change.
6675 (Entry_Index_Expression): Likewise.
6676 (Is_Potentially_Large_Family): New function extracted from...
6677 (Collect_Entry_Families): ...here. Call it to detect whether the family
6678 is potentially large.
6679 (Build_Entry_Count_Expression): If the family is potentially large, call
6680 Family_Size with 'Cap' set to true.
6681 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
6682 a protected version of an operation declared in the private part of
6683 a protected object, because they may be invoked through a callback.
6684 (Set_Privals): If the type of a private component is an anonymous access
6685 type, do not create a new itype for each protected body.
6686 If the body of a protected operation creates
6687 controlled types (including allocators for class-widetypes), the
6688 body of the corresponding protected subprogram must include a
6690 (Build_Activation_Chain_Entity): Build the chain entity for extended
6692 (Type_Conformant_Parameters): Use common predicate Conforming_Types
6693 to determine whether operation overrides an inherited primitive.
6694 (Build_Wrapper_Spec): Add code to examine the parents while looking
6695 for a possible overriding candidate.
6696 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
6697 hold an actual parameter value since its initialization is separated
6698 from the the declaration. Prevents errors on null-excluding access
6701 2007-04-06 Thomas Quinot <quinot@adacore.com>
6703 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
6704 Do an Unchecked_Conversion to handle the passage from the Underlying
6705 Type to the Base Type when calling Build_To_Any_Call and
6706 Build_From_Any_Call.
6707 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
6708 E_Constant, depending upon Variable formal.
6709 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
6710 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
6711 parameter that requires an extra constrained parameter, declare
6712 temporary for actual as a variable, not a constant.
6713 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
6714 the unit being compiled is the one that contains the stub type.
6715 Change primitive operation name for the RACW associated with a RAS
6716 from Call to _Call so it cannot clash with any legal identifier.
6717 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
6719 (Append_RACW_Bodies): New subprogram.
6720 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
6721 Add_Receiving_Stubs_To_Declarations functions.
6722 When expanding a package body, this list correspond to the
6723 statements in the HSS at the end of the pacakge.
6724 When expanding a package spec, this list correspond to the
6726 (Add_Receiving_Stubs_To_Declarations): Append the function
6727 registering the receiving stubs at the end of the 'Stmts' list.
6728 (RCI_Package_Locator): Pass the new Version generic formal when
6729 instantiating a RCI_Locator package.
6730 (Build_From_Any_Function): To compute the High bound for an
6731 unconstrained array actual, we add the Low bound with the length.
6732 Thus we must convert the low bound and the length to an appropriate
6733 type before doing the sum.
6734 (Build_Subprogram_Receiving_Stubs, PolyORB):
6735 * Retrieve the extra formals parameters at the
6736 end of the parameter stream.
6737 * Use Move_Any_Value to write back out parameters
6738 after executing the request as it is more efficient
6739 than Copy_Any_Value.
6740 * Build the any containing Extra Formals with the
6741 appropriate typecode.
6742 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
6743 empty Component_List.
6744 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
6745 the tree the declaration for an object that serves as actual parameter
6746 in server-side stubs.
6747 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
6748 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
6749 Use Build_Actual_Object_Declaration to prepare the actuals.

6751 Extra Constrained Parameters.
6752 (Build_General_Calling_Stubs): Set the parameter type to boolean for

6756 function with the first not implicit parent type.
6757 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
6758 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
6759 typecode from the Etype. Therefore we retrieve the correct typecode
6760 with a call to Get_Any_Type.
6761 (Copy_Specification): Do controlling formal type substitution based on
6762 Is_Controlling_Formal flag, instead of caller-provided object type.
6763 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
6764 a RACW primitive operation, we might get a subprogram declaration for an
6765 ancestor of the RACW designated type (not for the designated type
6766 itself), in the case where this operation is inherited. In this case we
6767 have no easy means of determining the original tagged type for which
6768 the primitive was declared, so instead we now rely on
6769 Copy_Specification to use the Is_Controlling_Formal flag to determine
6770 which formals require type substitution.

6775 * exp_intr.adb (Expand_Exception_Call): Calls to subprograms in
6776 GNAT.Current_Exception are not allowed if pragma Restrictions
6777 (No_Exception_Propagation) is set and in any case make the associated
6778 handler unsuitable as a target for a local raise statement.
6779 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
6780 run-time subprogram CW_Membership by call to Build_CW_Membership.
6781 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
6782 by a function call, a temporary must be created before expanding the
6783 Constructor_Call itself, to prevent out-of-order elaboration in the
6784 back-end when stack checking is enabled..
6786 2007-04-06 Ed Schonberg <schonberg@adacore.com>
6788 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
6789 result are the bounds of the left operand, not the right.
6791 2007-04-06 Ed Schonberg <schonberg@adacore.com>

6911 wide-string using the UTF-8 encoding. The S2WS macro supports now only
6912 standard 8bits encoding.
6913 (WS2SU): As above but converting from wide-sring to string.
6914 This is needed as it is necessary to have access to both versions in the
6915 runtime for the form parameter encoding support.
6916 This set of patch add support for the encoding form parameter.
6917 (S2WS): Improve implementation to handle cases where the filename is not
6918 UTF-8 encoded. In this case we default to using the current code page
6921 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
6922 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

6966 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
6967 __gnat_adjust_context_for_raise.
6968 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
6969 implementation of floating point operations as native x86 targets.
6970 So the FPU should be initialized in the same way using finit. Fix
6971 floating point operations accuracy issues.
6972 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
6973 member in struct sigaction, so as to avoid warning for incompatible

6992 Modify the loop that collects type references, to include interface
6993 types that the type implements. List each of these interfaces when
6994 building the entry for the type.
6995 (Generate_Definition): Initialize component Def and Typ of new entry
6996 in table Xrefs, to avoid to have these components unitialized.
6997 (Output_References): Split Is_Abstract flag into
6998 Is_Abstract_Subprogram and Is_Abstract_Type.
6999 (Generate_Reference): Add barrier to do not generate the warning

7040 2007-04-06 Robert Dewar <dewar@adacore.com>
7042 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
7043 it no longer destroys the contents of Name_Buffer or Name_Len and
7044 non-standard and invalid names are handled better.
7045 (Get_Decoded_Name_String): Improve performance by using
7046 Name_Has_No_Encodings flag in the name table.
7047 (Is_Valid_Name): New function to determine whether a Name_Id is valid.

7059 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
7060 illegal in Ada 95, in cases where it is legal. Change the warnings to
7061 errors in other cases. Don't give the error unless the "not null"
7062 parses properly. Correct the source position at which the error occurs.
7063 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
7064 P_Null_Exclusion, to suppress "not null" warnings.

7140 the default project path, initially done during elaboration of the
7142 If the prefix returned by Sdefault is null, get the prefix from a call
7143 to Executable_Prefix_Path.
7144 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is

7150 (Record_Other_Sources): Idem.
7151 (Locate_Directory): Add the possibility to create automatically missing
7152 directories when Setup_Projects is True.

7195 full word is no longer compared twice.
7197 2007-04-06 Ed Schonberg <schonberg@adacore.com>
7199 * sem_ch10.adb (Install_Limited_Context_Clauses.
7200 Expand_Limited_With_Clause): Use a new copy of selector name in the
7201 call to Make_With_Clause. This fixes the tree structure for ASIS
7202 purposes. Nothing is changed in the compiler behaviour.
7203 (Process_Body_Clauses): Handle properly use clauses whose prefix is
7205 (Install_Limited_With_Clauses): Do not install non-limited view when it
7206 is still incomplete.
7208 2007-04-06 Ed Schonberg <schonberg@adacore.com>
7209 Gary Dismukes <dismukes@adacore.com>
7211 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
7212 when capturing size information, instead of base type, which for a
7213 formal array type will be the unconstrained type.
7214 (Analyze_Formal_Object_Declaration): Add check for illegal default
7215 expressions for a formal in object of a limited type.
7216 (Instantiate_Object): Ditto.
7217 (Check_Formal_Package_Instance): Skip entities that are formal objects,
7218 because they were defaulted in the formal package and no check applies
7220 (Check_Formal_Package_Instance): Extend conformance check to other
7221 discrete types beyond Integer.
7222 (Process_Default): Copy directly the unmatched formal. A generic copy
7223 has already been performed in Analyze_Formal_Package.
7224 (Analyze_Associations): If a formal subprogram has no match, check for
7225 partial parametrization before looking for a default, to prevent
7227 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
7228 not set the instantiation environment before analyzing the actuals.
7229 Fixes regression on 8515-003 with implementation of AI-133.
7230 Set_Instance_Env checks whether the generic unit is a predefined
7231 unit, in which case the instance must be analyzed with the latest Ada
7232 mode. This setting must take place after analysis of the actuals,
7233 because the actuals must be analyzed and frozen in the Ada mode extant
7234 outside of the current instantiation.
7235 (Save_Env, Restore_Env): Preserve and restore the configuration
7236 parameters so that predefined units can be compiled in the proper Ada
7238 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
7239 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
7240 and Is_Abstract_Type.
7241 (Analyze_Formal_Package): For better error recovery, Add exception
7242 handler to catch Instantion_Error, which can be raised in
7243 Analyze_Associations

7246 Bob Duff <duff@adacore.com>
7247 Gary Dismukes <dismukes@adacore.com>
7249 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
7250 prefix type is a discriminated subtype of the type of the formal.
7251 (Analyze_Allocator): Collect all coextensions regardless of the context.
7252 Whether they can be allocated statically is determined in exp_ch4.
7253 (Analyze_Selected_Component): If the prefix is a limited view and the
7254 non-limited view is available, use the non-limited one.
7255 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
7256 therefore illegal), suggest a qualified expression rather than a type
7257 conversion, because a type conversion would be illegal in this context.
7258 (Anayze_Allocator): Trace recursively all nested allocators so that all
7259 coextensions are on the corresponding list for the root. Do no mark
7260 coextensions if the root allocator is within a declaration for a stack-
7261 allocated object, because the access discriminants will be allocated on
7263 (Analyze_Call): Remove restriction on calls to limited functions for the
7264 cases of generic actuals for formal objects, defaults for formal objects
7265 and defaults for record components.
7266 (Analyze_Allocator): Before analysis, chain coextensions on the proper
7267 element list. Their expansion is delayed until the enclosing allocator
7268 is processed and its finalization list constructed.
7269 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
7270 for an operation with the given name among the primitive operations of
7271 the corresponding record type.
7272 (Analyze_Selected_Component): If the prefix is a task type that
7273 implements an interface, and there is no entry with the given name,
7274 check whether there is another primitive operation (e.g. a function)
7276 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
7277 properly the indexing of a function call written in prefix form, where
7278 the function returns an array type, and all parameters of the function
7279 except the first have defaults.
7280 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
7281 the original operands, rather than relocating them, for efficiency and
7282 to work properly when an operand is overloaded.
7283 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
7284 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
7285 (Analyze_Selected_Component): If the prefix is a private extension, only
7286 scan the visible components, not those of the full view.
7287 (Try_Primitive_Operation): If the operation is a procedure, collect all
7288 possible interpretations, as for a function, because in the presence of
7289 classwide parameters several primitive operations of the type can match
7290 the given arguments.
7292 2007-04-06 Ed Schonberg <schonberg@adacore.com>
7293 Robert Dewar <dewar@adacore.com>
7295 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
7296 tag-indeterminate call to an abstract function, when the left-hand side
7298 (Analyze_Loop_Statement): Improve detection of infinite loops
7300 2007-04-06 Ed Schonberg <schonberg@adacore.com>
7301 Thomas Quinot <quinot@adacore.com>
7303 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
7304 out of Analyze_Package_Declaration, because processing must be applied
7305 to package bodies as well, for deferred constants completed by pragmas.
7306 (Analyze_Package_Declaration): When the package declaration being
7307 analyzed does not require an explicit body, call Check_Completion.
7308 (May_Need_Implicit_Body): An implicit body is required when a package
7309 spec contains the declaration of a remote access-to-classwide type.
7310 (Analyze_Package_Body): If the package contains RACWs, append the
7311 pending subprogram bodies generated by exp_dist at the end of the body.
7312 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
7313 Is_Abstract_Subprogram and Is_Abstract_Type.
7314 (Preserve_Full_Attributes): The full entity list is not an attribute
7315 that must be preserved from full to partial view.
7317 * sem_dist.adb (Add_RAS_Dereference_TSS):
7318 Change primitive name to _Call so it cannot clash with any legal
7319 identifier, and be special-cased in Check_Completion.
7320 Mark the full view of the designated type for the RACW associated with
7321 a RAS as Comes_From_Source to get proper view switching when installing
7322 private declarations.
7323 Provite a placeholder nested package body along with the nested spec
7324 to have a place for Append_RACW_Bodies to generate the calling stubs
7325 and stream attributes.
7327 2007-04-06 Ed Schonberg <schonberg@adacore.com>
7328 Robert Dewar <dewar@adacore.com>
7330 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
7331 that is a limited view, check the non-limited view if available.
7332 (Undefined): Refine error message for missing with of Text_IO
7333 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
7334 to distinguish real missing with cases.
7335 Fix format of all missing with messages
7336 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
7337 renaming as body when renamed entity is abstract.
7339 2007-04-06 Ed Schonberg <schonberg@adacore.com>
7340 Javier Miranda <miranda@adacore.com>
7342 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
7343 predicate recursive, to handle complex expressions on literals whose
7344 spurious ambiguity comes from the abstract interpretation of some
7346 (Interface_Present_In_Ancestor): Add support to concurrent record
7348 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
7349 Is_Abstract_Subprogram and Is_Abstract_Type.

7352 Javier Miranda <miranda@adacore.com>
7354 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
7355 dereference of a local object R created as a reference to another
7356 object O, use the access level of O.
7357 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
7358 rather than local Same_Formal_Type, to check whether protected operation
7359 overrides an inherited one.
7360 (Same_Formal_Type): New predicate, used when matching signatures of
7361 overriding synchronized operations, to handle the case when a formal
7362 has a type that is a generic actual.
7363 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
7364 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
7365 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
7366 syntactic ambiguities involving indexing of function calls that return
7368 (Abstract_Interface_List): New subprogram that returns the list of
7369 abstract interfaces associated with a concurrent type or a
7370 concurrent record type.
7371 (Interface_Present_In_Parent): New subprogram used to check if a
7372 given type or some of its parents implement a given interface.
7373 (Collect_Abstract_Interfaces): Add support for concurrent types
7374 with interface types.
7375 (Has_Abstract_Interfaces): Add support for concurrent types with
7377 (Is_Parent): New subprogram that determines whether E1 is a parent
7378 of E2. For a concurrent type its parent is the first element of its
7379 list of interface types; for other types this function provides the
7380 same result than Is_Ancestor.
7381 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
7382 (Collect_Synchronized_Interfaces): Removed because the subprogram
7383 Collect_Abstract_Interfaces provides this functionality.
7384 (Collect_Abstract_Interfaces): Minor update to give support to
7385 concurrent types and thus avoid undesired code duplication.
7386 (Get_Subprogram_Entity): Handle entry calls.
7387 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
7389 (Enter_Name): Do not give -gnatwh hiding warning for record component
7390 entities, they never result in hiding.

7400 (Local_Raise_Statements): New field in N_Exception_Handler_Node
7401 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

7415 before propagating exception.
7417 2007-04-06 Olivier Hainque <hainque@adacore.com>
7419 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
7420 an address always within the call instruction from a return address.
7422 2007-04-06 Olivier Hainque <hainque@adacore.com>
7423 Eric Botcazou <botcazou@adacore.com>
7425 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
7426 expression with a COMPOUND_EXPR including the call instead of emitting
7427 the call directly here.
7428 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
7429 high bound is constant and the slice is empty. Tidy.
7430 (tree_transform, case N_Op_Not): Handle properly the case where the
7431 operation applies to a private type whose full view is a modular type.
7432 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
7433 Address_Clause, use the associated Expression as the GNAT tree
7434 representing the choice value to ensure the corresponding GCC tree is
7436 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
7437 instead of just the operands, as the base GCC stabilize_reference does.
7438 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
7439 requested; otherwise fail.
7440 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
7442 2007-04-06 Thomas Quinot <quinot@adacore.com>

7445 implementation of UI_Div.
7446 (UI_Div): Reimplement as a call to UI_Div_Rem.
7447 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
7448 remainder, avoiding the cost of a multiplication and a subtraction.

7450 provides both quotient and remainder in a single computation.
7451 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic

7474 (gnat_install_builtins): Adjust comments.
7475 (builtin_function): Set DECL_BUILTIN_CLASS and DECL_FUNCTION_CODE before

7477 function declaration node.
7478 (builtin_decl_for): Search the builtin_decls list.
7480 2007-04-06 Eric Botcazou <botcazou@adacore.com>

7720 anonymous access types.
7721 (Valid_Conversion): For a conversion to a numeric type occurring in an
7722 instance or inlined body, no need to check that the operand type is
7723 numeric, since this has been checked during analysis of the template.

8495 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
8496 register in the final list objects containing class-wide interfaces;
8497 otherwise we incorrectly register the tag of the interface in the final
8499 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
8500 generate the wrapper if the parent primitive is abstract. This is
8501 required to report the correct error message.
8502 (Expand_N_Subtype_Indication): Do validity checks on range
8503 (Clean_Task_Names): If an initialization procedure includes a call to
8504 initialize a task (sub)component, indicate that the procedure will use
8505 the secondary stack.
8506 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
8507 compatibility for interfacing with CPP by default.
8508 (Expand_N_Object_Declaration): Only build an Adjust call when the
8509 object's type is a nonlimited controlled type.
8510 * exp_ch3.adb: Add with and use of Exp_Ch6.
8511 (Expand_N_Object_Declaration): Check for object initialization that is a
8512 call to build-in-place function and apply Make_Build_In_Place_Call_In_
8513 Object_Declaration to the call.
8514 (Freeze_Type): When the designated type of an RACW was not frozen at the
8515 point where the RACW was declared, validate the primitive operations
8516 with respect to E.2.2(14) when it finally is frozen.
8517 (Build_Initialization_Call,Expand_Record_Controller): Rename
8518 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
8519 return-by-reference has no meaning in Ada 2005.
8520 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
8521 to register tag of the immediate ancestor interfaces in the
8523 (Init_Secondary_Tags): Moved to the specification to allow the
8524 initialization of extension aggregates with abstract interfaces.
8525 (Build_Master_Renaming): Make public, for use by function declarations
8526 whose return type is an anonymous access type.
8527 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
8528 Insert_List_Before_And_Analyze after the generation of the specs
8529 associated with null procedures.
8530 (Expand_Tagged_Root): Update documentation in its specification.
8531 (Init_Secondary_Tags): Update documentation.
8532 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
8533 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
8534 then generate code to inherit the contents of the dispatch table
8535 directly from the ancestor.
8536 (Expand_Record_Controller): Insert controller component after tags of
8537 implemented interfaces.
8538 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
8539 create null procedure overridings when null procedures are inherited
8541 (Make_Null_Procedure_Specs): New procedure to generate null procedure
8542 declarations for overriding null primitives inherited from interfaces.
8543 (Is_Null_Interface_Procedure): New function in
8544 Make_Null_Procedure_Specs.
8545 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
8546 immediate ancestor of a tagged type is an abstract interface type we
8547 must generate the specification of the predefined primitives associated
8548 with controlled types (because the dispatch table of the ancestor is
8549 null and hence these entries cannot be inherited). This is required to
8550 elaborate well the dispatch table.

8558 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
8560 (Expand_N_In): Do validity checks on range
8561 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
8562 (Expand_N_Allocator): For "new T", if the object is constrained by
8563 discriminant defaults, allocate the right amount of memory, rather than
8564 the maximum for type T.
8565 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
8566 when the allocator is initialized by a build-in-place call, since the
8567 allocator is already rewritten as a reference to the function result,
8568 and this prevents an unwanted duplication of the function call.
8569 Add with and use of Exp_Ch6.
8570 (Expand_Allocator_Expresssion): Check for an allocator whose expression
8571 is a call to build-in-place function and apply
8572 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
8573 untagged designated types).
8574 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
8575 optimization if source or target is biased.
8576 (Expand_N_Allocator): Add comments for case of an allocator within a
8577 function that returns an anonymous access type designating tasks.
8578 (Expand_N_Allocator): apply discriminant checks for access
8579 discriminants of anonymous access types (AI-402, AI-416)

8584 Ed Schonberg <schonberg@adacore.com>
8586 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
8588 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
8589 (Expand_N_Assignment_Statement): Call
8590 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
8591 build-in-place function call. Currently, this can happen only for
8592 assignments that come from aggregates.
8593 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
8594 in order to alleviate the upward compatibility introduced by AI-318.
8595 (Expand_N_Extended_Return_Statement): Add support for handling the
8596 return object as a build-in-place result.
8597 (Expand_Non_Function_Return): Implement simple return statements nested
8598 within an extended return.
8599 (Enable_New_Return_Processing): Turn on the new processing of return
8601 (Expand_Non_Function_Return): For a return within an extended return,
8602 don't raise Program_Error, because Sem_Ch6 now gives a warning.
8603 (Expand_N_Extended_Return_Statement): Implement AI-318
8604 (Expand_Simple_Function_Return): Ditto.
8605 (Expand_N_If_Statement): Handle new -gnatwt warning
8606 (Expand_N_Case_Statement): Handle new -gnatwt warning
8607 (Expand_N_Assignment): Handle assignment to the Priority attribute of
8609 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
8610 validity checking of assignments to elementary record components.
8611 (Expand_N_Return_Statement): return Class Wide types on the secondary
8612 stack independantly of their controlled status since with HIE runtimes,
8613 class wide types are not potentially controlled anymore.
8615 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
8618 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
8619 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
8620 it expects a block, procedure, or task. The return statement will get
8621 turned into a block, and Expand_Cleanup_Actions will happen then.

8625 Bob Duff <duff@adacore.com>
8626 Gary Dismukes <dismukes@adacore.com>
8628 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
8630 (Expand_Inlined_Call): Tagged types are by-reference types, and
8631 therefore should be replaced by a renaming declaration in the expanded
8632 body, as is done for limited types.
8633 (Expand_Call): If this is a call to a function with dispatching access
8634 result, propagate tag from context.
8635 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
8637 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
8638 build-in-place when the right-hand side of an assignment is a
8639 build-in-place function call.
8640 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
8641 of the explicit dereference of the allocator to the result subtype of
8642 the build-in-place function. This is needed to satisfy type checking
8643 in cases where the caller's return object is created by an allocator for
8644 a class-wide access type and the type named in the allocator is a
8646 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
8647 conversion of the reference to the declared object to the result subtype
8648 of the build-in-place function. This is needed to satisfy type checking
8649 in cases where the declared object has a class-wide type. Also, in the
8650 class-wide case, change the type of the object entity to the specific
8651 result subtype of the function, to avoid passing a class-wide object
8652 without explicit initialization to the back end.
8653 (Register_Interface_DT_Entry): Moved outside the body of
8654 Freeze_Subprogram because this routine is now public; it is called from
8655 Check_Dispatching_Overriding to handle late overriding of abstract
8656 interface primitives.
8657 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
8658 adding an implicit access actual on a call to a build-in-place function.
8659 (Expand_Actuals): Test for an actual parameter that is a call to a
8660 build-in-place function and apply
8661 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
8662 (Is_Build_In_Place_Function): New function to determine whether an
8663 entity is a function whose calls should be handled as build-in-place.
8664 (Is_Build_In_Place_Function_Call): New function to determine whether an
8665 expression is a function call that should handled as build-in-place.
8666 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
8667 calls to build-in-place functions as the initialization of an allocator.
8668 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
8669 handling calls to build-in-place functions in contexts that do not
8670 involve init of a separate object (for example, actuals of subprogram
8672 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
8673 handling calls to build-in-place functions as the initialization of an
8675 (Detect_Infinite_Recursion): Add explicit parameter Process to
8676 instantiation of Traverse_Body to avoid unreferenced warning.
8677 (Check_Overriding_Inherited_Interfaces): Removed.
8678 (Register_Interface_DT_Entry): Code cleanup.
8679 (Register_Predefined_DT_Entry): Code cleanup.
8680 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
8681 inlined statements if within a transient scope.
8682 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
8683 formal parameters with occurrences of actuals in inlined body, establish
8684 visibility on the proper view of the actual's subtype for the body's
8686 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
8687 compatibility mode and we have an imported CPP subprogram because
8688 for now we assume that imported CPP primitives correspond with
8689 objects whose constructor is in the CPP side (and therefore we
8690 don't need to generate code to register them in the dispatch table).
8691 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
8692 aligned selected component.
8693 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
8694 the actual of an in-mode parameter is a type conversion.
8695 (Expand_Actuals): If the call does not come from source and the actual
8696 is potentially misaligned, let gigi handle it rather than rejecting the
8697 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
8698 Class Wide types as returning by reference independantly of their
8699 controlled status since with HIE runtimes class wide types are not
8700 potentially controlled anymore.
8702 2006-10-31 Ed Schonberg <schonberg@adacore.com>
8704 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
8705 references that are private components of the protected object.
8706 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
8707 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
8708 instantiation to deal with warnings.
8709 (Initialize_Protection): If expression for priority is non-static, use
8710 System_Priority as its expected type, in case the expression has not
8713 2006-10-31 Robert Dewar <dewar@adacore.com>
8715 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
8716 initialization of Homonym_Len.
8717 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
8718 names from fully qualified name. Fixes problem of duplicate
8719 external names differing only in the presence of such a block name.
8721 2006-10-31 Thomas Quinot <quinot@adacore.com>
8722 Pablo Oliveira <oliveira@adacore.com>
8724 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
8725 subprogram Ids, even if they are not yet assigned.
8726 (Build_Subprogram_Id): It is now this function that will take care of
8727 calling Assign_Subprogram_Ids if necessary.
8728 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
8729 should be done only once they are assigned.
8730 (Build_From_Any_Function, case of tagged types): Add missing call to
8732 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
8733 type for an RACW type.
8734 (Add_RACW_Features): When processing an RACW declaration for which the
8735 designated type is already frozen, enforce E.2.2(14) rules immediately.
8736 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
8737 special reordering of controlling formals.
8739 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
8740 associated stub type for an RACW type.
8742 2006-10-31 Ed Schonberg <schonberg@adacore.com>
8744 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
8745 fixed-point operations in an integer context, i.e. as operands of a
8746 conversion to an integer type, indicate that result must be rounded.
8748 2006-10-31 Robert Dewar <dewar@adacore.com>
8750 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
8751 cases, pass the encoding method, since it is now required by the run
8754 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
8755 assumption that Str'First = 1.
8756 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
8757 it on to the Value_Wide_Wide_Character call.
8758 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
8759 properly handles a string of the form quote-encoded_wide_char-quote.
8761 * s-wchcnv.adb: Minor reformatting
8763 2006-10-31 Javier Miranda <miranda@adacore.com>
8765 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
8766 run-time membership test to ensure that the constructed object
8767 implements the target abstract interface.
8769 2006-10-31 Robert Dewar <dewar@adacore.com>
8771 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
8772 Machine_Attribute pragma internally to implement the user pragma.
8773 Add processing for pragma Interface so that it is now completely
8774 equivalent to pragma Import.
8776 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
8777 so that it can be applied to all entities, including record components
8778 and enumeration literals.
8779 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
8780 priority ranges are correct, verify compatibility against task
8781 dispatching and locking policies, and if everything is correct an entry
8782 is added to the table containing priority specific dispatching entries
8783 for this compilation unit.
8784 (Delay_Config_Pragma_Analyze): Delay processing
8785 Priority_Specific_Dispatching pragmas because when processing the
8786 pragma we need to access run-time data, such as the range of
8787 System.Any_Priority.
8788 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
8789 Allow pragma Unreferenced as a context item
8790 Add pragma Preelaborable_Initialization
8791 (Analyze_Pragma, case Interface): Interface is extended so that it is
8792 now syntactically and semantically equivalent to Import.
8793 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
8794 insertion characters.
8795 Add handling for Pragma_Wide_Character_Encoding
8796 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
8797 never supercedes a real restriction, and that a real restriction
8798 always supercedes a warning.
8799 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

8806 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
8807 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
8808 Is_Inherently_Limited_Type, because return-by-reference has no meaning
8810 (Find_Node_To_Be_Wrapped): Use new method of determining the result
8811 type of the function containing a return statement, because the
8812 Return_Type field was removed. We now use the Return_Applies_To field.
8814 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
8815 (Build_Task_Image_Decl): If procedure is not called from an
8816 initialization procedure, indicate that function that builds task name
8817 uses the sec. stack. Otherwise the enclosing initialization procedure
8818 will carry the indication.
8819 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
8820 N_Object_Declaration instead.
8821 (Kill_Dead_Code): New interface to implement -gnatwt warning for
8822 conditional dead code killed, and change implementation accordingly.
8823 (Insert_Actions): Add N_Return_Object_Declaration case.
8824 Correct comment to mention N_Extension_Aggregate node.

8826 attempts to save information for global variables which cannot be
8828 (Get_Current_Value_Condition): Handle conditions the other way round
8829 (constant on left). Also handle right operand of AND and AND THEN
8830 (Set_Current_Value_Condition): Corresponding changes
8831 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
8832 (Get_Current_Value_Condition): Handle simple boolean operands
8833 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
8834 (Get_Current_Value_Condition): If the variable reference is within an
8835 if-statement, does not appear in the list of then_statments, and does
8836 not come from source, treat it as being at unknown location.
8837 (Get_Current_Value_Condition): Enhance to allow while statements to be
8838 processed as well as if statements.
8839 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
8841 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
8842 of loop. This is safe now that we fixed Kill_Current_Values.
8843 (OK_To_Do_Constant_Replacement): Check whether current scope is
8844 Standard, before examining outer scopes.
8846 2006-10-31 Vincent Celier <celier@adacore.com>

8863 * g-expect.adb: Add Warnings (Off) to prevent new warning
8865 * lib-xref.adb: Add handling of Last_Assignment field
8866 (Generate_Reference): Centralize handling of pragma Obsolescent here
8867 (Generate_Reference): Accept an implicit reference generated for a
8868 default in an instance.
8869 (Generate_Reference): Accept a reference for a node that is not in the
8870 main unit, if it is the generic body corresponding to an subprogram
8873 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
8875 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
8877 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
8879 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
8880 use clauses, to avoid messages on packages used to qualify, and also
8881 to avoid messages from obsolescent units.
8882 (Warn_On_Useless_Assignments): Don't generate messages for imported
8883 and exported variables.
8884 (Warn_On_Useless_Assignments): New procedure

8890 (Last_Assignment): New field for useless assignment warning
8892 2006-10-31 Olivier Hainque <hainque@adacore.com>
8894 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
8895 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
8897 2006-10-31 Bob Duff <duff@adacore.com>
8898 Robert Dewar <dewar@adacore.com>
8899 Ed Schonberg <schonberg@adacore.com>
8901 * g-awk.adb (Default_Session, Current_Session): Compile this file in
8902 Ada 95 mode, because it violates the new rules for AI-318.
8904 * g-awk.ads: Use overloaded subprograms in every case where we used to
8905 have a default of Current_Session. This makes the code closer to be
8906 correct for both Ada 95 and 2005.
8908 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
8909 code, relying on the fact that the compiler generates a warning
8910 instead of an error in -gnatg mode.
8912 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
8913 E_Return_Statement entity kind.
8914 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
8916 * par.adb (P_Interface_Type_Definition): Addition of one formal to
8917 report an error if the reserved word abstract has been previously found.
8918 (SS_End_Type): Add E_Return for new extended_return_statement syntax.

8921 parenthesized range attribute usage
8922 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
8924 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
8925 in the syntax for extended_return_statement. This is not in the latest
8926 RM, but the ARG is expected to issue an AI allowing this.
8927 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
8928 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
8929 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
8930 P_Return_Statement): Parse the new syntax for extended_return_statement.
8932 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
8933 Output_End_Missing): Add error-recovery code for the new
8934 extended_return_statement syntax; that is, the new E_Return entry on
8937 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
8938 limited to nonlimited, because otherwise we violate the new Ada 2005
8939 rules about returning limited types in function Create_AST_Handler in
8942 * sem.adb (Analyze): Add cases for new node kinds
8943 N_Extended_Return_Statement and N_Return_Object_Declaration.
8945 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
8946 type is in the same category as type of context before applying check,
8947 to prevent anomalies in instantiations.
8948 (Resolve_Aggregate): Remove test for limited components in aggregates.
8949 It's unnecessary in Ada 95, because if it has limited components, then
8950 it must be limited. It's wrong in Ada 2005, because limited aggregates
8952 (Resolve_Record_Aggregate): Move check for limited types later, because
8953 OK_For_Limited_Init requires its argument to have been resolved.
8954 (Get_Value): When copying the component default expression for a
8955 defaulted association in an aggregate, use the sloc of the aggregate
8956 and not that of the original expression, to prevent spurious
8957 elaboration errors, when the expression includes function calls.
8958 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
8959 were missing. We also didn't handle qualified expressions. Now also
8960 allow function calls. Use new common routine OK_For_Limited_Init.
8961 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
8962 with space can upper case letter).
8964 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
8965 Has_Static_Discriminants flag
8966 (Record_Type_Declaration): Diagnose an attempt to declare an interface
8967 type with discriminants.
8968 (Process_Range_Expr_In_Decl): Do validity checks on range
8969 (Build_Discriminant_Constraints): Use updated form of
8970 Denotes_Discriminant.
8971 (Process_Subtype): If the subtype is a private subtype whose full view
8972 is a concurrent subtype, introduce an itype reference to prevent scope
8974 (Build_Derived_Record_Type, Collect_Interface_Primitives,
8975 Record_Type_Declaration): The functionality of the subprograms
8976 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
8977 is now performed by a single routine.
8978 (Build_Derived_Record_Type): If the type definition includes an explicit
8979 indication of limitedness, then the type must be marked as limited here
8980 to ensure that any access discriminants will not be treated as having
8981 a local anonymous access type.
8982 (Check_Abstract_Overriding): Issue a detailed error message when an
8983 abstract subprogram was not overridden due to incorrect mode of its
8985 (Analyze_Private_Extension_Declaration): Add support for the analysis of
8986 synchronized private extension declarations. Verify that the ancestor is
8987 a limited or synchronized interface or in the generic case, the ancestor
8988 is a tagged limited type or synchronized interface and all progenitors
8989 are either limited or synchronized interfaces.
8990 Derived_Type_Declaration): Check for presence of private extension when
8991 dealing with synchronized formal derived types.
8992 Process_Full_View): Enchance the check done on the usage of "limited" by
8993 testing whether the private view is synchronized.
8994 Verify that a synchronized private view is completed by a protected or
8996 (OK_For_Limited_Init_In_05): New function.
8997 (Analyze_Object_Declaration): Move check for limited types later,
8998 because OK_For_Limited_Init requires its argument to have been resolved.
8999 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
9000 in order to alleviate the upward compatibility introduced by AI-318.
9001 (Constrain_Corresponding_Record): If the constraint is for a component
9002 subtype, mark the itype as frozen, to avoid out-of-scope references to
9003 discriminants in the back-end.
9004 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
9005 this subprogram against wrong sources.
9006 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
9007 discriminant of limited type completed with a protected type, when the
9008 discriminant is used to constrain a private component of the type, and
9009 expansion is disabled.
9010 (Find_Type_Of_Object): Do not treat a return subtype that is an
9011 anonymous subtype as a local_anonymous_type, because its accessibility
9012 level is the return type of the enclosing function.
9013 (Check_Initialization): In -gnatg mode, turn the error "cannot
9014 initialize entities of limited type" into a warning.
9015 (OK_For_Limited_Init): Return true for generated nodes, since it
9016 sometimes violates the legality rules.
9017 (Make_Incomplete_Declaration): If the type for which an incomplete
9018 declaration is created happens to be the currently visible entity,
9019 preserve the homonym chain when removing it from visibility.
9020 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
9021 inherited subprograms.
9022 (Access_Definition): If this is an access to function that is the return
9023 type of an access_to_function definition, context is a type declaration
9024 and the scope of the anonymous type is the current one.
9025 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
9026 incomplete subtype to the set of private dependents of the original
9028 (Constrain_Discriminated_Type): Emit an error message whenever an
9029 incomplete subtype is being constrained.
9030 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
9031 corresponding subtype of the full view of the original incomplete type.
9032 (Check_Incomplete): Properly detect invalid usage of incomplete types

9070 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
9071 call it with -static-libgcc, as there are some platforms, such as
9072 Darwin, where one of these two switches is compulsory to link.
9074 2006-10-31 Vincent Celier <celier@adacore.com>
9076 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
9077 instead of ADA_PROJECT_PATH, for the project path.
9078 (Gnatls): When displaying the project path directories, use host dir
9081 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
9082 names in the project path, as absolute paths may correspond to
9083 multi-valued VMS logical names.

9116 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
9118 (Layout_Variant_Record): Retrieve the discriminants from the entity
9119 rather than from the type definition, because in the case of a full
9120 type for a private type we need to take the discriminants from the
9122 (Layout_Component_List): When applying the Max operator to variants with
9123 a nonstatic size, check whether either operand is static and scale that
9124 operand from bits to storage units before applying Max.
9125 (Layout_Type): In VMS, if a C-convention access type has no explicit
9126 size clause (and does not inherit one in the case of a derived type),
9127 then the size is reset to 32 from 64.
9129 2006-10-31 Vincent Celier <celier@adacore.com>
9131 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
9132 its file has already been loaded, according to the unit being loaded,
9133 not to the current value of Multiple_Unit_Index.
9135 2006-10-31 Thomas Quinot <quinot@adacore.com>

9164 (Initialize): Remove, no longer used
9165 (Ar): If Ar_Exec is null, get the location of the archive builder and,
9166 if there is one, the archive indexer. Fail if the archive builder cannot
9168 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
9171 2006-10-31 Ed Schonberg <schonberg@adacore.com>
9173 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
9174 Process_Body_Clauses): If the context of a body includes a use clause
9175 for P.Q then a with_clause for P in the same body is not redundant,
9176 even if the spec also has a with_clause on P.
9177 Add missing continuation mark to error msg
9178 (Build_Limited_Views): A limited view of a type is tagged if its
9179 declaration includes a record extension.
9180 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
9181 node, even if the subunit has errors. This avoids malfunction by
9182 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
9183 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
9184 generation of obsolescent messages for with statements (cannot do
9185 this too early, or we cannot implement avoiding the messages in the
9186 case of obsolescent units withing obsolescent units).
9187 (Install_Siblings): If the with_clause is on a remote descendant of
9188 an ancestor of the current compilation unit, find whether there is
9189 a sibling child unit that is immediately visible.
9190 (Remove_Private_With_Clauses): New procedure, invoked after completing
9191 the analysis of the private part of a nested package, to remove from
9192 visibility the private with_clauses of the enclosing package
9194 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
9195 now centralized in Generate_Reference.
9196 (Install_Limited_Context_Clauses): Remove superfluous error
9197 message associated with unlimited view visible through use
9198 and renamings. In addition, at the point in which the error
9199 is reported, we add the backslash to the text of the error
9200 to ensure that it is reported as a single error message.
9201 Use new // insertion for some continuation messages
9202 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
9203 to create implicit with_clause for parent unit mentioned in original
9204 limited_with_clause.

9271 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
9272 dot, instead of replacing only the first '_'.
9274 * prj-part.adb (Parse): Convert project file path to canonical form
9276 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
9277 extended, the project id of the project extending it is recorded in its
9278 data, even when it has already been processed as an imported project.
9280 2006-10-31 Robert Dewar <dewar@adacore.com>

9286 Robert Dewar <dewar@adacore.com>
9288 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
9289 only a restriction warning is active for the given restriction. This is
9290 desirable because we do not want to modify code in the case where only
9292 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
9293 causes overriding of real restrictions.
9294 Take advantage of new No_Restrictions constant.

9327 Generalizes previous mechanism to handle attribute references nested
9328 arbitrarily deep within the aggregate.
9329 (Analyze_Access_Attribute): An access attribute whose prefix is a type
9330 can appear in an aggregate if this is a default-initialized aggregate
9331 for a self-referential type.

9340 (Resolve_Attribute, case 'Access et al): Take into account anonymous
9341 access types of return subtypes in extended return statements. Remove
9342 accessibility checks on anonymous access types when Unchecked_Access is

9345 a class-wide interface to a tagged type.
9346 Add support for the attribute Priority.
9347 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
9348 whether the designated type is discriminated with a constrained partial
9349 view and require static matching in that case.
9350 Add local variable Des_Btyp. The Designated_Type
9351 of an access to incomplete subtype is either its non-limited view if
9352 coming from a limited with or its etype if regular incomplete subtype.

9355 Fix predicate to identify and allow cases of (expander-generated)
9356 references to tag of designated object of a RACW.
9357 (Validate_Static_Object_Name): In Ada 2005, a formal object is
9358 non-static, and therefore cannot appear as a primary in a preelaborable
9360 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
9361 Has_Read_Write_Attributes.
9362 (Has_Read_Write_Attributes): Reimplement in termes of

9370 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
9371 useless assignments here and conditionalize it on absence of exception
9373 (Analyze_Exception_Handlers): Small code reorganization of error
9374 detection code, for new handling of formal packages.

9387 synchronized formal derived type is a synchronized tagged type.
9388 (Instantiate_Formal_Package): When creating the instantiation used to
9389 validate the actual package of a formal declared without a box, check
9390 whether the formal itself depends on a prior actual.

9392 identifiers of the formals in the renaming declaration, for ASIS use.
9393 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating

9398 AI-317 (partial parametrization) is fully implemented.
9399 (Validate_Private_Type_Instance): Add check for actual which
9400 must have preelaborable initialization
9401 Use new // insertion for some continuation messages
9402 (Analyze_Formal_Object_Declaration): Change usage of Expression to
9403 Default_Expression. Add type retrieval when the declaration has an
9404 access definition. Update premature usage of incomplete type check.
9405 (Check_Access_Definition): New subsidiary routine. Check whether the
9406 current compilation version is Ada 05 and the supplied node has an
9408 (Instantiate object): Alphabetize local variables. Handle the creation
9409 of new renaming declarations with respect to the kind of definition
9410 used - either an access definition or a subtype mark. Guard against
9411 unnecessary error message in the context of anonymous access types after
9412 they have been resolved. Add check for required null exclusion in a
9413 formal object declaration.
9414 (Switch_View): A private subtype of a non-private type needs to be
9415 switched (the base type can have been switched without its private
9416 dependents because of the last branch of Check_Private_View.
9417 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
9419 (Instantiate_Type): Emit an error message whenever a class-wide type of
9420 a tagged incomplete type is used as a generic actual.

9431 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
9433 (New_Stream_Subprogram): When processing an attribute definition clause
9434 for a stream-oriented subprogram, record an entity node occurring at
9435 the point of clause to use for checking the visibility of the clause,
9436 as defined by 8.3(23) as amended by AI-195.
9437 (New_Stream_Subprogram): New procedure, factoring behaviour from both
9438 New_Stream_Function and New_Stream_Procedure.

9444 Javier Miranda <miranda@adacore.com>
9445 Robert Dewar <dewar@adacore.com>
9447 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
9448 generate the same errors compiling under -gnatc.
9449 (Try_Object_Operation): If no candidate interpretation succeeds, but
9450 there is at least one primitive operation with the right name, report
9451 error in call rather than on a malformed selected component.
9452 (Analyze_Selected_Component): If the prefix is an incomplete type from
9453 a limited view, and the full view is available, use the full view to
9454 determine whether this is a prefixed call to a primitive operation.
9455 (Operator_Check): Verify that a candidate interpretation is a binary
9456 operation before checking the type of its second formal.
9457 (Analyze_Call): Add additional warnings for function call contexts not
9459 (Analyze_Allocator): Move the check for "initialization not allowed for
9460 limited types" after analyzing the expression. This is necessary,
9461 because OK_For_Limited_Init looks at the structure of the expression.
9462 Before analysis, we don't necessarily know what sort of expression it
9463 is. For example, we don't know whether F(X) is a function call or an
9464 indexed component; the former is legal in Ada 2005; the latter is not.
9465 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
9466 were missing. We also didn't handle qualified expressions. Now also
9467 allow function calls. Use new common routine OK_For_Limited_Init.
9468 (Analyze_Type_Conversion): Do not perform some legality checks in an
9469 instance, because the error message will be redundant or spurious.
9470 (Analyze_Overloaded_Selected_Component): Do not do style check when
9471 setting an entity, since we do not know it is the right entity yet.
9472 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
9473 (Analyze_Overloaded_Selected_Component): Same change
9474 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
9475 since regular incomplete subtypes are transformed into corresponding
9476 subtypes of their full views.
9477 (Complete_Object_Operation): Treat name of transformed subprogram call
9478 as coming from source, for browsing purposes.
9479 (Try_Primitive_Operation): If formal is an access parameter, compare
9480 with base type of object to determine whether it is a primitive
9482 (Operator_Check): If no interpretation of the operator matches, check
9483 whether a use clause on any candidate might make the operation legal.
9484 (Try_Class_Wide_Operation): Check whether the first parameter is an
9485 access type whose designated type is class-wide.
9487 2006-10-31 Robert Dewar <dewar@adacore.com>
9488 Ed Schonberg <schonberg@adacore.com>
9489 Gary Dismukes <dismukes@adacore.com>
9491 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
9492 warn on infinite loops.
9493 Add \\ to some continuation messages
9494 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
9495 (Process_Bounds): If the bounds are integer literals that result from
9496 constant-folding, and they carry a user-defined type, preserve that type
9497 rather than treating this as an integer range.
9498 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
9499 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
9500 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
9501 left hand side of assignment.
9502 (Analyze_Assignment): Add suport to manage assigments to the attribute
9503 priority of a protected object.
9504 (Check_Possible_Current_Value_Condition): Allow fully qualified names
9505 not just identifiers.
9506 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
9507 or AND THEN for possible tracking.
9508 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
9509 case of while loops so we can track values in the loop body.
9511 2006-10-31 Ed Schonberg <schonberg@adacore.com>
9512 Hristian Kirtchev <kirtchev@adacore.com>
9513 Bob Duff <duff@adacore.com>
9515 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
9516 procedure cannot be a protected operation (it is a basic_declaration,
9517 not a subprogram_declaration).
9518 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
9519 Subp. Add logic for entry processing.
9520 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
9521 Determine whether an entry or subprogram of a protected or task type
9522 override an inherited primitive of an implemented interface.
9523 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
9524 Update the actual used in calls to Check_Overriding_Indicator.
9525 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
9526 generate the proper reference to the parent unit, for cross-reference.
9527 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
9529 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
9530 (Add_Extra_Formal): Revise procedure to allow passing in associated
9531 entity, scope, and name suffix, and handle setting of the new
9532 Extra_Formals field.
9533 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
9534 pass new parameters. Add support for adding the new extra access formal
9535 for functions whose calls are treated as build-in-place.
9536 (Analyze_A_Return_Statement): Correct casing in error message.
9537 Move Pop_Scope to after Analyze_Function_Return, because an extended
9538 return statement really is a full-fledged scope. Otherwise, visibility
9539 doesn't work right. Correct use of "\" for continuation messages.
9540 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
9541 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
9542 the node doesn't get properly marked as analyzed.
9543 (Analyze_Subprogram_Body): If subprogram is a function that returns
9544 an anonymous access type that denotes a task, build a Master Entity
9546 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
9547 proper usage of null exclusion in a result definition.
9548 (Process_Formals): Code cleanup and new error message.
9549 (Process_Formals): Detect incorrect application of null exclusion to
9551 (Conforming_Types): Handle conformance between [sub]types and itypes
9552 generated for entities that have null exclusions applied to them.
9553 (Maybe_Primitive_Operation): Add an additional type retrieval when the
9554 base type is an access subtype. This case arrises with null exclusions.
9555 (New_Overloaded_Entity): Do not remove the overriden entity from the
9556 homonym chain if it corresponds with an abstract interface primitive.
9557 (Process_Formals): Replace membership test agains Incomplete_Kind with a
9558 call to the synthesized predicate Is_Incomplete_Type.
9559 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
9561 (Analyze_Subprogram_Declaration): Check that abstract interface
9562 primitives are abstract or null.
9563 (Analyze_Subprogram_Specification): Remove previous check for abstract
9564 interfaces because it was not complete.
9565 (Has_Interface_Formals): Removed.
9567 2006-10-31 Ed Schonberg <schonberg@adacore.com>
9568 Javier Miranda <miranda@adacore.com>
9570 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
9571 of Analyze_Package_Body, to create Itype references for anonymous
9572 access types created in the package declaration, whose designated types
9573 may have only a limited view.
9574 (Analyze_Package_Specification): For the private part of a nested
9575 package, install private_with_clauses of enclosing compilation unit if
9576 we are in its visible part.
9577 (Declare_Inherited_Private_Subprograms): Complete barrier
9578 to ensure that the primitive operation has an alias to some parent
9579 primitive. This is now required because, after the changes done for the
9580 implementation of abstract interfaces, the contents of the list of
9581 primitives has entities whose alias attribute references entities of
9582 such list of primitives.
9583 (Analyze_Package_Specification): Simplify code that handles parent units
9584 of instances and formal packages.
9585 (Uninstall_Declarations): Check the convention consistency among
9586 primitive overriding operations of a tagged record type.
9588 2006-10-31 Robert Dewar <dewar@adacore.com>
9589 Hristian Kirtchev <kirtchev@adacore.com>
9590 Javier Miranda <miranda@adacore.com>
9591 Ed Schonberg <schonberg@adacore.com>
9593 * sem_ch8.adb: Minor error msg rewording
9594 (Undefined): When checking for misspellings, invert arguments (to get
9595 expected and found set right)
9596 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
9597 (Analyze_Generic_Renaming): Same fix
9598 (Use_One_Package): Do not take into account the internal entities of
9599 abstract interfaces during the analysis of entities that are marked
9600 as potentially use-visible.
9601 (Find_Type): Handle the case of an attribute reference for
9602 implementation defined attribute Stub_Type (simply let the analysis of
9603 the attribute reference rewrite it).
9604 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
9605 type that appears in a Use_Type clause.
9606 (Analyze_Object_Renaming): Add support for renaming of the Priority
9608 (Find_Type): In Ada 2005, a task type can be used within its own body,
9609 when it appears in an access definition.
9610 (Analyze_Object_Renaming): Remove warning on null_exclusion.
9611 (Analyze_Object_Renaming): Introduce checks for required null exclusion
9612 in a formal object declaration or in a subtype declaration.
9613 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
9614 (Check_Null_Exclusion): New local routine to
9615 Analyze_Subprogram_Renaming. Check whether the formals and return
9616 profile of a renamed subprogram have required null exclusions when
9617 their counterparts of the renaming already impose them.
9618 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
9619 Determine whether an entity is inside a generic scope.
9620 (In_Open_Scope): First pass of documentation update.
9621 (Find_Expanded_Name): Add support for shadow entities associated with
9622 limited withed packages. This is required to handle nested packages.
9623 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
9624 that makes a renaming of a limited withed package illegal.
9626 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
9627 Ed Schonberg <schonberg@adacore.com>
9629 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
9630 Check_Overriding_Indicator.
9631 (Analyze_Task_Definition): Ditto.
9632 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
9633 (Check_Overriding_Indicator): To find overridden interface operation,
9634 examine only homonyms that have an explicit subprogram declaration, not
9635 inherited operations created by an unrelated type derivation.
9636 (Check_Overriding_Indicator): When checking for the presence of "null"
9637 in a procedure, ensure that the queried node is a procedure
9639 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
9640 type when the formal is an access to variable.
9641 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
9642 (Analyze_Task_Type): Same addition
9643 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
9644 provide navigation capabilities for entries.

9647 Ed Schonberg <schonberg@adacore.com>
9648 Javier Miranda <miranda@adacore.com>
9649 Gary Dismukes <dismukes@adacore.com>
9651 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
9652 inherited from an interface ancestor by another interface in the
9653 context of an instance as 'late'.
9654 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
9655 of a call to a function that dispatches on access result.
9656 (Check_Dispatching_Operation): In case of late overriding of a primitive
9657 that covers abstract interface subprograms we register it in all the
9658 secondary dispatch tables associated with abstract interfaces.
9659 (Check_Dispatching_Call): Add check that a dispatching call is not made
9660 to a function with a controlling result of a limited type. This is a
9661 current implementation restriction.
9662 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
9663 (Check_Dispatching_Operation): Do no emit a warning if the controlling
9664 argument is an interface type that is a generic formal.
9665 (Is_Interface_Subprogram): Removed.
9666 (Check_Dispatching_Operation): If the subprogram is not a dispatching
9667 operation, check the formals to handle the case in which it is
9668 associated with an abstract interface type.
9670 2006-10-31 Robert Dewar <dewar@adacore.com>
9671 Ed Schonberg <schonberg@adacore.com>

9685 Hristian Kirtchev <kirtchev@adacore.com>
9686 Javier Miranda <miranda@adacore.com>
9688 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
9689 subprogram type to provide better diagnostics in case of ambiguity.
9690 (Covers): Handle coverage of formal and actual anonymous access types in
9691 the context of generic instantiation.
9692 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
9693 abstract interface types; this is required to handle concurrent types
9694 with discriminants and abstract interface types.
9695 (Covers): Include type coverage of both regular incomplete subtypes and
9696 incomplete subtypes of incomplete type visibles through a limited with
9699 2006-10-31 Robert Dewar <dewar@adacore.com>
9700 Hristian Kirtchev <kirtchev@adacore.com>
9701 Ed Schonberg <schonberg@adacore.com>
9703 * sem_util.ads, sem_util.adb (Enter_Name): Exclude -gnatwh warning
9704 messages for entities in packages which are not used.
9705 (Collect_Synchronized_Interfaces): New procedure.
9706 (Overrides_Synchronized_Primitive): New function.

9708 Add missing continuation marks in error msgs
9709 (Unqualify): New function for removing zero or more levels of
9710 qualification from an expression. There are numerous places where this
9711 ought to be used, but we currently only deal properly with zero or one
9713 (In_Instance); The analysis of the actuals in the instantiation of a
9714 child unit is not within an instantiation, even though the parent
9715 instance is on the scope stack.
9716 (Safe_To_Capture_Value): Exclude the case of variables that are
9718 (Check_Obsolescent): Removed
9719 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
9720 is an aliased view, even when rewritten as a reference to the target
9721 object in an assignment.
9722 (Get_Subprogram_Entity): New function
9723 (Known_To_Be_Assigned): New function
9724 (Type_Access_Level): Compute properly the access level of a return

9731 has a null exclusion depending on its Nkind.
9732 Change Is_Lvalue to May_Be_Lvalue
9733 (May_Be_Lvalue): Extensive additional code to deal with subprogram
9734 arguments (IN parameters are not Lvalues, IN OUT parameters are).
9735 (Safe_To_Capture_Value): Extend functionality so it can be used for
9736 the current value condition case.
9737 (Has_Compatible_Alignment): New function
9738 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
9739 objects to handle the Ada 2005 case, where aliasedness no longer implies
9740 that the object is constrained. In particular, for dereferenced names,
9741 the designated object must be assumed to be unconstrained.
9742 (Kill_Current_Values): Properly deal with the case where we encounter
9743 a loop in the scope chain.
9744 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
9746 (Compile_Time_Constraint_Error): Improve error message in error case

9752 2006-10-31 Robert Dewar <dewar@adacore.com>
9754 * s-osinte-tru64.adb:
9755 Mark Asm statements Volatile to prevent warnings (seems a
9756 reasonable change anyway)

9787 N_Extended_Return_Statement.
9788 (Procedure_To_Call): Move to a different place to make room in
9789 N_Extended_Return_Statement.
9790 (Return_Type): Removed this field to make room in return statements
9792 (Return_Statement_Entity): New field in return statements, in part to
9793 replace Return_Type, and in part to support the fact that return
9794 statements are now pushed on the scope stack during semantic analysis.
9795 (Return_Object_Declarations): New field to support extended return
9797 (N_Extended_Return_Statement): New node for extended_return_statement
9799 (N_Return_Object_Declaration): New node for part of
9800 extended_return_statement nonterminal. Needed because all the necessary
9801 fields won't fit in N_Extended_Return_Statement.
9802 Generic_associations now carry the Box_Present flag, to indicate a
9803 default for an actual in a partially parametrized formal package.
9805 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
9806 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma
9807 and for the new predefined dispatching policies: EDF_Across_Priorities,

9821 print null exclusion twice in the case of an access definition,
9822 Implement new -gnatL switch
9823 Remove N_Return_Object_Declaration. We now use
9824 N_Object_Declaration instead. Implement the case for
9825 N_Extended_Return_Statement. Alphabetize the cases.
9826 Add cases for new nodes N_Extended_Return_Statement and
9827 N_Return_Object_Declaration. The code is not yet written.
9828 Update the output for N_Formal_Object_Declaration
9829 and N_Object_Renaming_Declaration.
9830 (Write_Itype): Account for the case of a modular integer subtype whose
9831 base type is private.
9833 2006-10-31 Arnaud Charlet <charlet@adacore.com>

9848 * s-scaval.adb (Initialize): Add new Boolean flag AFloat that is set
9849 True when AAMP extended floating-point is in use (48-bit). Change type
9850 ByteLF to ByteLLF, add new array type ByteLF and condition the size of
9851 the two byte array types on AFloat. Change type of IV_Ilf overlay
9852 variable from Byte8 to ByteLF. Add appropriate initializations of
9853 floating-point overlays for AAMP cases.

9881 2006-10-31 Olivier Hainque <hainque@adacore.com>
9883 * s-stchop.ads: make this unit preelaborate. This is desirable in
9884 general and made mandatory by the use of this unit by s-taprop which
9885 is itself preelaborate.
9887 * s-stchop-vxworks.adb (Set_Stack_Info, Task_Descriptor type): Add
9888 Td_Events component.

9906 When not in verbose mode and Ellipse is True, display "..." for the
9907 first argument with Display set to False.
9908 (Build_Global_Archive): Always set Display True for the first object
9909 file. Call Display_Command with Ellipse set to True.

10481 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
10482 abstract interface type, the static analysis is not enough to know if
10483 the interface is implemented or not by the source tagged type. Hence
10484 we must pass the work to the expander to generate the required code to
10485 evaluate the conversion at run-time.
10486 (Resolve_Equality_Op): Do not apply previous
10487 transformation if expansion is disasbled, to prevent anomalies when
10488 locating global references in a generic unit.

10826 other basic tools. The full version that includes the Ada 2005 stuff

11160 save/restore routines.
11161 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

11163 Since we are changing the tree format anyway, also get rid of the
11164 junk obsolete Immediate_Errors flag.
11165 (Tree_Read): Change the way of reading Tree_Version_String - now we

11256 (Freeze_Record_Type): Do not generate the tables associated with
11257 timed and conditional dispatching calls through synchronized
11258 interfaces if compiling under No_Dispatching_Calls restriction.
11259 When compiling for Ada 2005, for a nonabstract
11260 type with a null extension, call Make_Controlling_Function_Wrappers
11261 and insert the wrapper function declarations and bodies (the latter
11262 being appended as freeze actions).
11263 (Predefined_Primitive_Bodies): Do not generate the bodies of the
11264 predefined primitives associated with timed and conditional
11265 dispatching calls through synchronized interfaces if we are
11266 compiling under No_Dispatching_Calls.

11268 service is available before generating a call.
11269 (Make_Controlling_Function_Wrappers): New procedure.
11270 (Expand_N_Full_Type_Declaration): Create a class-wide master for
11271 access-to-limited-interfaces because they can be used to reference
11272 tasks that implement such limited interface.
11273 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
11274 procedure spec and body of the Offset_To_Top function that is generated
11275 when the parent of a type with discriminants has secondary dispatch
11277 (Init_Secondary_Tags): Handle the case in which the parent of the type
11278 containing secondary dispatch tables has discriminants to generate the
11279 correct arguments to call Set_Offset_To_Top.
11280 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
11282 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
11283 Add Wide_[Wide_]Expanded_Name.
11284 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
11285 the same functionality of Get_Prim_Op_Address but applied to predefined
11286 primitive operations because the pointers to the predefined primitives
11287 are now saved in a separate table.
11288 (Parent_Size): Modified to get access to the separate table of primitive
11289 operations or the parent type.
11290 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
11291 functionality of Set_Prim_Op_Address but applied to predefined primitive
11293 (Set_Signature): New subprogram used to store the signature of a DT.
11294 (Displace): If the Offset_To_Top value is not static then call the
11295 function generated by the expander to get such value; otherwise use
11296 the value stored in the table of interfaces.
11297 (Offset_To_Top): The type of the actual has been changed to Address to
11298 give the correct support to tagged types with discriminants. In this
11299 case this value is stored just immediately after the tag field.
11300 (Set_Offset_To_Top): Two new formals have been added to indicate if the
11301 offset_to_top value is static and hence pass this value to the run-time
11302 to store it in the table of interfaces, or else if this value is dynamic
11303 and then pass to the run-time the address of a function that is
11304 generated by the expander to provide this value for each object of the
11307 * rtsfind.ads (Default_Prin_Op_Count): Removed.
11308 (Default_Prim_Op_Count): New entity

11317 Make_Adjust_Call done for a newly-allocated object.
11319 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
11320 in a subprogram are wrapped in a cleanup block, indicate that the
11321 subprogram contains an inner block with an exception handler.
11322 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
11323 Adjust call is for a newly-allocated object. In that case we must not
11324 assume that the finalization list chain pointers are correct (since they
11325 come from a bit-for-bit copy of the original object's pointers) so if
11326 the attach level would otherwise be zero (no change), we set it to 4
11327 instead to cause the pointers to be reset to null.
11329 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
11330 reset chain pointers to null.
11332 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11334 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
11335 string, and the context requires a loop for the assignment (e.g.
11336 because the left-hand side is packed), generate a unique name for the
11337 temporary that holds the string, to prevent spurious name clashes.

11344 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
11345 return unconstrained arrays.
11347 (Expand_Call): An indirect call through an access parameter of a
11348 protected operation is not a protected call.
11349 Add circuit to raise CE in Ada 2005 mode following call
11350 to Raise_Exception.
11351 (Register_DT_Entry): Do nothing if
11352 the run-time does not give support to abstract interfaces.
11353 (Freeze_Subprogram): In case of dispatching operations, do not generate
11354 code to register the operation in the dispatch table if the source
11355 is compiled with No_Dispatching_Calls.
11356 (Register_Predefined_DT_Entry): Generate code that calls the new
11357 run-time subprogram Set_Predefined_Prim_Op_Address instead of
11358 Set_Prim_Op_Address.
11360 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
11361 on array assignments if the right-hand side is a function call that has
11362 been inlined. Check is performed on the assignment in the block.
11363 (Process_Bounds): If bounds and range are overloaded, apply preference
11364 rule for root operations to disambiguate, and diagnose true ambiguity.
11365 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
11366 a tag-indeterminate right-hand side even when Expander_Active is True.
11367 Needed to ensure that dispatching calls to T'Input are allowed and
11368 get the tag of the target class-wide object.
11370 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
11371 an inherited primitive operation that already overrides several
11372 abstract interface primitives. For transitivity, the new entity must
11373 also override all the abstract interface primitives covered by the
11374 inherited overriden primitive.
11375 Emit warning if new entity differs from homograph in same scope only in
11376 that one has an access parameter and the other one has a parameter of
11377 a general access type with the same designated type, at the same
11378 position in the signature.
11379 (Make_Inequality_Operator): Use source locations of parameters and
11380 subtype marks from corresponding equality operator when creating the
11381 tree structure for the implicit declaration of "/=". This does not
11382 change anything in behaviour except that the decoration of the
11383 components of the subtree created for "/=" allows ASIS to get the
11384 string images of the corresponding identifiers.
11385 (Analyze_Return_Statement): Remove '!' in warning message.
11386 (Check_Statement_Sequence): Likewise.
11387 (Analyze_Subprogram_Body): For an access parameter whose designated type
11388 is an incomplete type imported through a limited_with clause, use the
11389 type of the corresponding formal in the body.
11390 (Check_Returns): Implicit return in No_Return procedure now raises
11391 Program_Error with a compile time warning, instead of beging illegal.
11392 (Has_Single_Return): Function returning unconstrained type cannot be
11393 inlined if expression in unique return statement is not an identifier.
11394 (Build_Body_To_Inline): It is possible to inline a function call that
11395 returns an unconstrained type if all return statements in the function
11396 return the same local variable. Subsidiary procedure Has_Single_Return
11397 verifies that the body conforms to this restriction.
11399 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
11400 same type, and one of them is of an anonymous access type, convert
11401 the other operand to it, so that this is a valid binary operation for
11403 (Resolve_Type_Conversion): Handle subtypes of protected types and
11404 task types when accessing to the corresponding record type.
11405 (Resolve_Allocator): Add '\' in 2-line warning message.
11406 Remove '!' in warning message.
11407 (Resolve_Call): Add '\' in 2-line warning message.
11408 (Valid_Conversion): Likewise.
11409 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
11410 resulting type may be an access type with an implicit dereference.
11411 Obtain the proper component from the designated type.
11412 (Make_Call_Into_Operator): Handle properly a call to predefined equality
11413 given by an expanded name with prefix Standard, when the operands are
11414 of an anonymous access type.
11415 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
11416 Explicit_Dereference and Resolve_Selected_Component, to verify that the
11417 prefix of the expression is not of an incomplete type. Allows full
11418 diagnoses of all semantic errors.
11419 (Resolve_Actuals): If the actual is an allocator whose directly
11420 designated type is a class-wide interface we build an anonymous
11421 access type to use it as the type of the allocator. Later, when
11422 the subprogram call is expanded, if the interface has a secondary
11423 dispatch table the expander will add a type conversion to force
11424 the displacement of the pointer.
11425 (Resolve_Call): If a function that returns an unconstrained type is
11426 marked Inlined_Always and inlined, the call will be inlined and does
11427 not require the creation of a transient scope.
11428 (Check_Direct_Boolean_Op): Removed
11429 (Resolve_Comparison_Op): Remove call to above
11430 (Resolve_Equality_Op): Remove call to above
11431 (Resolve_Logical_Op): Inline above, since this is only call.
11432 (Valid_Conversion): Handle properly conversions between arrays of
11433 convertible anonymous access types.
11436 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
11437 the literal in an unchecked conversion, because GCC 4.x needs a static
11438 value for a string bound.
11440 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11441 Hristian Kirtchev <kirtchev@adacore.com>
11443 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
11444 components of the corresponding record, take into account component
11445 definitions that are access definitions.
11446 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
11447 procedure is not considered a dispatching call and will be expanded
11450 2006-02-13 Javier Miranda <miranda@adacore.com>
11452 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
11453 controlling argument of the dispatching call is an abstract interface
11454 class-wide type then we use it directly.
11455 Check No_Dispatching_Calls restriction.
11456 (Default_Prim_Op_Position): Remove the code that looks for the last
11457 entity in the list of aliased subprograms. This code was wrong in
11459 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
11460 when the source is compiled with the No_Dispatching_Calls restriction.
11461 (Init_Predefined_Interface_Primitives): No need to inherit primitives
11462 if we are compiling with restriction No_Dispatching_Calls.
11463 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
11464 subprograms if we are compiling under No_Dispatching_Calls restriction.
11465 (Make_DT): Generate a dispatch table with a single dummy entry if
11466 we are compiling with the No_Dispatching_Calls restriction. In
11467 addition, in this case we don't generate code that calls to the
11468 following run-time subprograms: Set_Type_Kind, Inherit_DT.
11469 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
11470 of this subprogram if compiling with the No_Dispatching_Calls
11472 (Expand_Type_Conversion): Instead of using the actual parameter,
11473 the argument passed as parameter to the conversion function was
11474 erroneously referenced by the expander.
11475 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
11476 Set_Predefined_Primitive_Op_Address and Set_Signature.
11477 (Expand_Dispatching_Call): Generate call to
11478 Get_Predefined_Prim_Op_Address for predefined primitives.
11479 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
11480 predefined primitives.
11481 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
11482 primitives we reserve one dummy entry to ensure that the tag does not
11483 point to some memory that is associated with some other object. In
11484 addition, remove all the old code that generated the assignments
11485 associated with the signature of the dispatch table and replace them
11486 by a call to the new subprogram Set_Signature.
11487 (Set_All_DT_Position): Change the algorithm because now we have a
11488 separate dispatch table associated with predefined primitive operations.
11489 (Expand_Interface_Conversion): In case of non-static offset_to_top
11490 add explicit dereference to get access to the object after the call
11491 to displace the pointer to the object.
11492 (Expand_Interface_Thunk): Modify the generation of the actual used
11493 in the calls to the run-time function Offset_To_Top to fulfil its
11495 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
11497 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11499 * exp_dist.adb (Copy_Specification): For access parameters, copy
11500 Null_Exclusion flag, which will have been set for stream subprograms
11503 2006-02-13 Pascal Obry <obry@adacore.com>
11505 * expect.c (__gnat_expect_portable_execvp): New implementation. The
11506 previous implementation was using the C runtime spawnve routine but
11507 the corresponding wait was using directly the Win32 API. This was
11508 causing some times a lock when waiting for an event using
11509 WaitForSingleObject in __gnat_waitpid. This new implementation uses
11510 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
11511 API fixes this problem.
11513 2006-02-13 Robert Dewar <dewar@adacore.com>
11515 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

11523 array reference that is an explicit dereference, mark the converted
11524 (packed) array reference as analyzed to prevent a forthcoming
11525 reanalysis from resetting its type to the original (non-packed) array

11529 Javier Miranda <miranda@adacore.com>
11530 Eric Botcazou <ebotcazou@adacore.com>
11532 * exp_util.ads, exp_util.adb (Find_Prim_Op,
11533 Is_Predefined_Primitive_Operation): When
11534 searching for the predefined equality operator, verify that operands
11535 have the same type.
11536 (Is_Predefined_Dispatching_Operation): Remove the code that looks
11537 for the last entity in the list of aliased subprograms. This code
11538 was wrong in case of renamings.
11539 (Set_Renamed_Subprogram): New procedure
11540 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
11541 Exp_Type constant computed when entering this subprogram.

11543 (OK_To_Do_Constant_Replacement): New function
11544 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
11545 (Side_Effect_Free): An attribute reference 'Input is not free of
11546 side effect, unlike other attributes that are functions. (from code
11548 (Remove_Side_Effects): Expressions that involve packed arrays or records
11549 are copied at the point of reference, and therefore must be marked as
11550 renamings of objects.
11551 (Is_Predefined_Dispatching_Operation): Return false if the operation is
11552 not a dispatching operation.
11555 (Remove_Side_Effects): Lift enclosing type conversion nodes for
11556 elementary types in all cases.
11558 2006-02-13 Javier Miranda <miranda@adacore.com>
11560 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
11561 task types when accessing to the corresponding record type.
11562 Remove '!' in warning message.
11564 2006-02-13 Olivier Hainque <hainque@adacore.com>
11566 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
11567 to avoid useless and space inefficient overalignments on targets where
11568 Max_Alignment is larger than 16.
11570 2006-02-13 Pascal Obry <obry@adacore.com>
11572 * g-catiio.adb (Sec_Number): New type used to compute the number of
11573 seconds since 1-1-1970.
11574 (Image) [Natural]: The parameter was an Integer, as we can't deal with
11575 negative numbers (years, months...) it is better to have a Natural here.
11577 (Image) [Number]: Change parameter from Long_Integer to Number.
11578 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
11579 overflow for dates past year 2038.
11581 2006-02-13 Matthew Heaney <heaney@adacore.com>
11583 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
11586 2006-02-13 Arnaud Charlet <charlet@adacore.com>
11588 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
11590 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
11591 finalization can occur normally.
11593 2006-02-13 Vincent Celier <celier@adacore.com>
11595 * gnatcmd.adb (Rules_Switches): New table
11596 (Add_To_Rules_Switches): New procedure
11597 (GNATCmd): For command CHECK, put all options following "-rules" in the
11598 Rules_Switches table. Append these -rules switches after the -cargs
11601 2006-02-13 Robert Dewar <dewar@adacore.com>
11603 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
11604 These two cases were generating incorrect output, and if this unit
11605 was built with checks on, generated a discriminant mismatch constraint
11608 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11609 Robert Dewar <dewar@adacore.com>
11611 * lib-xref.adb (Get_Type_Reference): For a private type whose full
11612 view is an array type, indicate the component type as well, for
11613 navigation purposes.
11614 (Generate_Reference): Don't consider array ref on LHS to be a case
11615 of violating pragma Unreferenced.
11616 Do not give Ada 2005 warning except on real reference.
11618 2006-02-13 Vincent Celier <celier@adacore.com>
11620 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
11621 main source, add switch -mdebug-main=_ada_ so that the executable can
11622 be debugged by the standard VMS debugger.
11623 (Gnatmake): Set No_Main_Subprogram to True when there is no main
11624 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
11625 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
11626 of the last source, as the binding and linking phases are never
11628 Set all executable obsolete when rebuilding a library.
11630 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
11633 2006-02-13 Javier Miranda <miranda@adacore.com>
11636 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
11637 code to improve the error message reported when the program has
11638 declarations of abstract interface types and it is not compiled with
11639 the -gnat05 switch.
11640 (P_Access_Definition): Reorganize the code to improve the error
11641 message reported when the new Ada 2005 syntax for anonymous
11642 access types is used and the program is not compiled with the

11665 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
11666 unknown, use the location of the project to report the error.

11682 Prj.Nmsc.Check with parameter When_No_Sources.
11683 (Process): New parameter When_No_Sources. Call Check with parameter
11685 (Copy_Package_Declarations): New procedure to copy renamed parameters
11686 and setting the location of the declared attributes to the location
11687 of the renamed package.

11695 When removing nodes (attributes Source_Dirs, Source_Files,
11696 Source_List_File and package Naming), save the comments and attach the
11697 saved comments to the newly created nodes.

11707 aliased entities to look for the overriden abstract interface
11709 (Is_Interface_Subprogram): Complete documentation.
11710 (Check_Dispatching_Operation): Do not generate code to register the
11711 operation in the dispatch table if the source is compiled with
11712 restriction No_Dispatching_Calls.
11713 (Override_Dispatching_Operation): Check for illegal attempt to override
11714 No_Return procedure with procedure that is not No_Return
11715 (Check_Dispatching_Call): Suppress the check for an abstract operation
11716 when the original node of an actual is a tag-indeterminate attribute
11717 call, since the attribute, which must be 'Input, can never be abstract.
11718 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
11719 call to the Input attribute (even when rewritten).
11720 (Propagate_Tag): Augment comment to indicate the possibility of a call
11721 to an Input attribute.
11723 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
11724 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
11726 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
11727 No_Wide_Characters is no longer partition-wide
11728 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
11731 2006-02-13 Douglas Rupp <rupp@adacore.com>
11733 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
11735 2006-02-13 Javier Miranda <miranda@adacore.com>
11737 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
11738 handles default-initialized components to keep separate the management
11739 of this feature but also avoid the unrequired resolution and
11740 expansion of components that do not have partially initialized
11742 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
11743 (Check_Bounds): Likewise.
11744 (Check_Length): Likewise.
11746 2006-02-13 Javier Miranda <miranda@adacore.com>
11747 Ed Schonberg <schonberg@adacore.com>
11749 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
11750 abstract interface type call analyze_and_resolve to expand the type
11751 conversion into the corresponding displacement of the
11752 reference to the base of the object.
11753 (Eval_Attribute, case Width): For systems where IEEE extended precision
11754 is supported, the maximum exponent occupies 4 decimal digits.
11755 (Accessibility_Message): Add '\' in 2-line warning message.
11756 (Resolve_Attribute): Likewise.
11757 (case Attribute_Access): Significantly revise checks
11758 for illegal access-to-subprogram Access attributes to properly enforce
11759 the rules of 3.10.2(32/2).
11760 Diagnose use of current instance with an illegal attribute.
11762 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
11764 (Enclosing_Generic_Unit): New function to return a node's innermost
11765 enclosing generic declaration node.
11766 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
11767 (Type_Access_Level): The accessibility level of anonymous acccess types
11768 associated with discriminants is that of the current instance of the
11769 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
11770 (Compile_Time_Constraint_Error): Handle case of conditional expression.
11771 (Kill_Current_Values_For_Entity): New function
11772 (Enter_Name): Change formal type to Entity_Id
11774 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
11775 Ed Schonberg <schonberg@adacore.com>
11776 Gary Dismukes <dismukes@adacore.com>
11778 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
11779 Analyze_Compilation_Unit.
11780 Detect and warn on redundant with clauses detected in a package spec
11781 and/or body when -gnatwr is used.
11782 (Analyze_Context): Analyze config pragmas before other items
11783 (Install_Context_Items): Don't analyze config pragmas here
11784 (Install_Limited_Withed_Unit): Set limited entity of package in
11785 with_clause so that cross-reference information or warning messages on
11786 unused packages can be properly generated
11787 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
11788 has Error_Posted set. Prevent infinite loops in illegal programs.
11789 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
11790 to the point of the error test requiring the current unit to be private.
11791 This ensures that private with clauses are not exempted from the basic
11792 checking for being a descendant of the same library unit parent as a
11793 withed private descendant unit.
11794 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
11795 handle private with clauses properly, as well as to account for cases
11796 where the withed unit is a public descendant of a private ancestor
11797 (in which case the current unit must be a descendant of the private
11798 ancestor's parent). The spec comments were updated accordingly. Also,
11799 the old error message in this subprogram was replaced with error
11800 messages that mirror the errors tested and reported by
11801 Check_Private_Child_Unit.
11802 Parameter and variable names improved for readability.
11803 (Install_Limited_Context_Clauses): Remove test for a withed unit being
11804 private as the precondition for calling
11805 Check_Private_Limited_Withed_Unit since that subprogram has been
11806 revised to test public units as well as private units.

11813 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
11814 that Scope_Stack.First = 1.
11815 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
11816 were not always properly handled previously.
11817 (Formal_Entity): Complete rewrite, to handle properly some complex case
11818 with multiple levels of parametrization by formal packages.
11819 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
11820 to the corresponding derived type declaration for proper semantics.
11822 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
11823 (Check_Component): Enforce restriction on components of
11824 unchecked_unions: a component in a variant cannot contain tasks or
11826 (Unchecked_Union): Allow nested variants and multiple discriminants, to
11828 Add pragma Ada_2005 (synonym for Ada_05)
11829 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
11830 were not always properly handled previously.
11831 Document that pragma Propagate_Exceptions has no effect
11832 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
11833 (Set_Convention_From_Pragma): Check that if a convention is
11834 specified for a dispatching operation, then it must be
11835 consistent with the existing convention for the operation.
11836 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
11837 longer required to specify an vtable-ptr component in the record. For
11838 compatibility reasons we leave the support for the previous definition.
11839 (Analyze_Pragma, case No_Return): Allow multiple arguments
11841 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
11842 non-overrideen inherited operation with a controlling result as
11843 illegal only its implicit declaration comes from the derived type
11844 declaration of its result's type.
11845 (Check_Possible_Deferred_Completion): Relocate the object definition
11846 node of the subtype indication of a deferred constant completion rather
11847 than directly analyzing it. The analysis of the generated subtype will
11848 correctly decorate the GNAT tree.
11849 (Record_Type_Declaration): Check whether this is a declaration for a
11850 limited derived record before analyzing components.
11851 (Analyze_Component_Declaration): Diagnose record types not explicitly
11852 declared limited when a component has a limited type.
11853 (Build_Derived_Record_Type): Code reorganization to check if some of
11854 the inherited subprograms of a tagged type cover interface primitives.
11855 This check was missing in case of a full-type associated with a private
11857 (Constant_Redeclaration): Check that the subtypes of the partial and the
11858 full view of a constrained deferred constant statically match.
11859 (Mentions_T): A reference to the current type in an anonymous access
11860 component declaration must be an entity name.
11861 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
11862 class_wide type to refer to full type, not to the incomplete one.
11863 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
11864 available. Required to give support to the certified run-time.
11865 (Analyze_Component_Declaration): In case of anonymous access components
11866 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
11867 (Process_Discriminants): For an access discriminant, use the
11868 discriminant specification as the associated_node_for_itype, to
11869 simplify accessibility checks.
11871 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11872 Javier Miranda <miranda@adacore.com>
11874 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
11875 abstract interpretations on an operator, remove interpretations that
11876 yield Address or a type derived from it, if one of the operands is an
11878 (Try_Object_Operation.Try_Primitive_Operation,
11879 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
11880 location when creating the new reference to a primitive or class-wide
11881 operation as a part of rewriting a subprogram call.
11882 (Try_Primitive_Operations): If context requires a function, collect all
11883 interpretations after the first match, because there may be primitive
11884 operations of the same type with the same profile and different return
11885 types. From code reading.
11886 (Try_Primitive_Operation): Use the node kind to choose the proper
11887 operation when a function and a procedure have the same parameter
11889 (Complete_Object_Operation): If formal is an access parameter and prefix
11890 is an object, rewrite as an Access reference, to match signature of
11891 primitive operation.
11892 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
11893 by an expanded name with prefix Standard, when the operands are of an
11894 anonymous access type.
11895 (Remove_Abstract_Operations): If the operation is abstract because it is
11896 inherited by a user-defined type derived from Address, remove it as
11897 well from the set of candidate interpretations of an overloaded node.
11898 (Analyze_Membership_Op): Membership test not applicable to cpp-class
11901 2006-02-13 Bob Duff <duff@adacore.com>
11903 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
11904 redundant use clauses.
11905 In particular, if the scope of two use clauses overlaps, but one is not
11906 entirely included in the other, we should not warn. This can happen
11907 with nested packages.
11908 (Analyze_Subprogram_Renaming): Protect the compiler against previously
11909 reported errors. The bug was reported when the compiler was built
11910 with assertions enabled.
11911 (Find_Type): If the node is a 'Class reference and the prefix is a
11912 synchronized type without a corresponding record, return the type
11915 2006-02-13 Javier Miranda <miranda@adacore.com>
11917 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
11918 if this is the full-declaration associated with a private declaration
11919 that implement interfaces, then the private type declaration must be
11921 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
11922 as aliased. The use of the 'access attribute is not available for such
11923 object (for this purpose the object should be explicitly marked as
11924 aliased, but being an anonymous type this is not possible).
11926 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11927 Robert Dewar <dewar@adacore.com>
11929 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
11930 compilation unit is an elaboration scope.
11931 (Add_Task_Proc): Add '\' in 2-line warning message.
11932 (Activate_All_Desirable): Deal with case of unit with'ed by parent
11934 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11935 Javier Miranda <miranda@adacore.com>
11937 * sem_type.adb (Write_Overloads): Improve display of candidate
11939 (Add_One_Interp): Do not add to the list of interpretations aliased
11940 entities corresponding with an abstract interface type that is an
11941 immediate ancestor of a tagged type; otherwise we have a dummy
11942 conflict between this entity and the aliased entity.
11943 (Disambiguate): The predefined equality on universal_access is not
11944 usable if there is a user-defined equality with the proper signature,
11945 declared in the same declarative part as the designated type.
11946 (Find_Unique_Type): The universal_access equality operator defined under
11947 AI-230 does not cover pool specific access types.
11948 (Covers): If one of the types is a generic actual subtype, check whether
11949 it matches the partial view of the other type.
11951 2006-02-13 Thomas Quinot <quinot@adacore.com>
11953 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
11954 line. This is necessary to allow In_Extended_Main_Unit to provide
11955 correct results for itypes while writing out expanded source.
11956 (Close_File): No need to update the source_index_table here since it's
11957 now done for each line.
11959 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11960 Robert Dewar <dewar@adacore.com>
11962 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
11963 preserve the source unit where the itype is declared, and prevent a
11965 (Note_Implicit_Run_Time_Call): New procedure
11966 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
11969 * sprint.ads: Document use of $ for implicit run time routine call
11971 2006-02-13 Quentin Ochem <ochem@adacore.com>
11973 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
11976 2006-02-13 Bob Duff <duff@adacore.com>
11978 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
11979 Scan_Unsigned, so we do not scan leading blanks and sign twice.
11980 Integer'Value("- 5") and Integer'Value("-+5") now correctly
11981 raise Constraint_Error.
11983 * s-vallli.adb (Scan_Long_Long_Integer): Call
11984 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
11985 do not scan leading blanks and sign twice.
11986 Integer'Value("- 5") and Integer'Value("-+5") now correctly
11987 raise Constraint_Error.
11989 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
11990 Scan_Long_Long_Unsigned): Split out most of the processing from
11991 Scan_Long_Long_Unsigned out into
11992 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
11993 This prevents scanning leading blanks and sign twice.
11994 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
11997 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
11998 out most of the processing from Scan_Unsigned out into
11999 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
12000 This prevents scanning leading blanks and sign twice.
12002 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
12003 use with Modular'Value attribute.
12004 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
12007 2006-02-13 Robert Dewar <dewar@adacore.com>
12009 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
12011 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>

12014 (PPC VxWorks): Likewise.
12015 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
12016 (forced_callee): Make non-inlinable and non-pure.
12017 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

12132 ({declaraction},Delete_Binder_Generated_Files,{initialization}): Change
12133 Ada bind file prefix on VMS from b$ to b__.
12135 * gnatlink.adb (Process_Args): Call Add_Src_Search_Dir for -I in
12136 --GCC so that Get_Target_Parameters can find system.ads.
12137 (Gnatlink): Call Get_Target_Parameters in mainline.
12138 Initialize standard packages for Targparm.
12139 Change some Hostparm.OpenVMS checks to Targparm.OpenVMS_On_Target.

12159 (../../vxaddr2line): gnatlink with targext.o.
12160 (TOOLS_LIBS): Move targext.o to precede libgnat.
12161 (init.o, initialize.o): Minor clean up in dependencies.

12202 * a-taster.ads, a-taster.adb: New files.
12204 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
12205 link to the version that does nothing. This way the task termination
12206 routine is not executed twice for the environment task when finishing
12207 because of an unhandled exception.
12209 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
12210 handler because of an unhandled exception.
12212 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
12213 System.Tasking.Utilities instead of that in System.Tasking.Stages.
12215 * s-finimp.adb (initialization code): Modify the soft link for the
12216 finalization of the global list instead of Adafinal.
12218 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
12219 non-tasking version of the soft link for task termination. We do
12220 nothing since if we are using the non-tasking version it
12221 means that the task termination functionality is not used.
12222 (Null_Finalize_Global_List): Add this null version for the procedure
12223 in charge of finalizing the global list for controlled objects.
12224 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
12225 instead for handling run-time termination in a more flexible way.
12226 (Adafinal_NT): This new procedure will take care of finalizing the
12227 global list for controlled objects if needed, but no tasking
12230 * s-tarest.adb (Task_Lock): Do not try to lock again the
12231 Global_Task_Lock if we already own it. Otherwise, we get blocked in
12232 some run-time operations.
12233 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
12234 until all nested locks have been released.
12235 (Task_Wrapper): Call the fall-back task termination handler. It
12236 applies to all tasks but the environment task.
12237 (Finalize_Global_Tasks): Add the call for the task termination
12238 procedure for the environment task.
12239 (Task_Wrapper): suppress warnings around declaration of
12240 Secondary_Stack_Address.
12242 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
12243 moved to the Common_ATCB record.
12244 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
12245 Common_ATCB record.
12246 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
12247 Common_ATCB record.
12249 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
12250 Fall_Back_Handler, and Specific_Handler.
12252 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
12253 defined in Ada.Task_Termination, to avoid circular dependencies.
12254 (Termination_Handler): Redefine this type here, alredy defined in
12255 Ada.Task_Termination, for avoiding circular dependencies.
12256 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
12257 for storing task termination handlers. In addition,
12258 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
12259 Common_ATCB because it is used by both the regular and the restricted
12261 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
12262 Common_ATCB because it is used by both the regular and the restricted
12264 (Common_ATCB): Added a dynamic task analyzer field.
12266 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
12267 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
12268 (Task_Wrapper): Call the task termination handler. It applies to all
12269 tasks but the environment task.
12270 (Finalize_Global_Tasks): Call the task termination procedure for the
12271 environment task. The call to Finalize_Global_List is now performed
12272 using the soft links mechanism.
12273 (Task_Wrapper): added dynamic stack analysis.
12275 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
12276 potentially blocking operations has been moved from
12277 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
12278 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
12279 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
12280 this run-time check.
12282 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
12283 of task termination procedure.
12284 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
12285 link for the task termination procedure.
12287 * bindusg.adb: (Bindusg): Added documentation for -u option.
12289 * bindgen.adb (Get_Main_Ada) Added handling of dynamic stack analysis.
12290 (Get_Main_C): Add handling of dynamic stack analysis.
12291 (Gen_Output_File_C): Add external functions for dynamic stack analysis.

12297 * opt.ads: Added flags used by dynamic stack measurement.
12298 (Max_Line_Length): Remove (not used anymore)
12300 * s-io.ads, s-io.adb (Standard_Error): new subprogram
12301 (Standart_Output): new subprogram
12302 (Set_Output): new subprogram
12303 (Put): now uses the value of Current_Out to know if the output has to be
12304 send to stderr or stdout.
12306 * s-stausa.ads: Complete implementation.
12308 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
12310 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
12311 list of Ada 05 files.
12312 (GNAT Library Units): Add AltiVec files.

12326 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
12327 to the specification because the frontend generates code that uses this
12329 (Set_Interface_Table): Add missing assertion.
12330 Update documentation describing the run-time structure.
12331 (Displace): New subprogram that displaces the pointer to the object
12332 to reference one of its secondary dispatch tables.
12333 (IW_Membership): Modified to use the new table of interfaces.
12334 (Inherit_TSD): Modified to use the new table of interfaces.
12335 (Register_Interface_Tag): Use the additional formal to fill the
12336 contents of the new table of interfaces.
12337 (Set_Interface_Table): New subprogram that stores in the TSD the
12338 pointer to the table of interfaces.
12339 (Set_Offset_To_Top): Use the additional formal to save copy of

12352 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
12353 in all the calls to Expand_Interface_Thunk. Instead of referencing the
12354 record component containing the tag of the secondary dispatch table we
12355 have to use the Offset_To_Top run-time function to get this information;
12356 otherwise if the pointer to the base of the object has been displace
12357 we get a wrong value if we use the 'position attribute.
12359 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
12360 all the calls to Expand_Interface_Thunk.
12361 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

12364 ensure that the interfaces implemented by the ancestors are placed
12365 at the header of the generated list.
12366 (Expand_Interface_Conversion): Handle the case in which the displacement
12367 associated with the interface conversion is not statically known. In

12371 Get_Tagged_Kind and Set_Tagged_Kind.
12372 (Tagged_Kind): New function that determines the tagged kind of a type
12373 with respect to limitedness and concurrency and returns a reference to

12395 RE_TK_Tagged, RE_TK_Task.
12397 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
12398 Init_Secondary_Tags_Internal to allow its use with interface types and
12399 also to generate the code for the new additional actual required
12400 by Set_Offset_To_Top.
12401 (Build_Init_Statements): In case of components associated with abstract
12402 interface types there is no need to generate a call to its IP.
12403 (Freeze_Record_Type): Generate Select Specific Data tables only for

12412 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
12413 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
12414 properly protected objects and attach handler in the case of the
12415 restricted profile.

12428 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
12429 pointer initialization values. Make a SAVE_EXPR instead. Add comments
12430 about the use and expansion of SAVE_EXPRs in the various possible
12431 renaming handling cases.
12432 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
12433 abusing DECL_FCONTEXT.

12552 component associated with the secondary table of an abstract interface
12553 type, return the entity associated with such abstract interface type.
12554 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
12555 base type to create anonymous subtype, because entity may be a locally
12556 declared subtype or generic actual.
12557 (Find_Interface): New subprogram that given a tagged type and one of its
12558 component associated with the secondary table of an abstract interface
12559 type, return the entity associated with such abstract interface type.

12600 (Analyze_Component_Declaration): A limited component is
12601 legal within a protected type that implements an interface.
12602 (Collect_Interfaces): Do not add to the list the interfaces that
12603 are implemented by the ancestors.
12604 (Derived_Type_Declaration): If the parent of the full-view is an
12605 interface perform a transformation of the tree to ensure that it has
12606 the same parent than the partial-view. This simplifies the job of the
12607 expander in order to generate the correct object layout, and it is
12608 needed because the list of interfaces of the full-view can be given in
12610 (Process_Full_View): The parent of the full-view does not need to be
12611 a descendant of the parent of the partial view if both parents are
12613 (Analyze_Private_Extension_Declaration): If declaration has an explicit
12614 "limited" the parent must be a limited type.

12628 (Process_Full_View): Improve the check for the "no hidden interface"
12629 rule as defined by AI-396.
12631 2005-12-09 Robert Dewar <dewar@adacore.com>
12633 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
12634 types, not on record subtypes.
12635 (Freeze_Entity): Code cleanup. Add barrier to the loop
12636 that generates the references for primitive operations. This allows to
12637 remove an unnecessary exception handler.

12687 * sem_cat.adb (Validate_RCI_Subprogram_Declaration): Revise test for
12688 available user-specified stream attributes on limited parameters to
12689 also test the type directly rather than only its underlying type (for
12690 Ada 95) and, in the case of Ada 2005, to check that the user-specified
12691 attributes are visible at the point of the subprogram declaration.
12692 For Ada 2005, the error message is modified to indicate that the

12725 types use the corresponding record type. This was not needed before
12726 the implementation of Ada 2005 synchronized types because
12727 concurrent types were never tagged types in Ada 95.

12950 * gen-soccon.c: Complete value expansion should not be performed on
12951 TARGET, as it has the form of a math expression, and some components
12952 may be platform-defined macros.
12953 For VxWorks, generate the OK and ERROR values.
12954 New constants giving the sizes of the components of C struct timeval.

12966 deal with different cases of static and dynamic elaboration checks (all
12967 checks does not count in the first case, but does in the second).

12973 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
12974 elementary types using the operator in standard. It is cleaner not to
12975 modify the programmers intent, especially in the case of floating-point.
12976 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
12977 it did not matter because we always rewrote a/=b to not(a=b).
12978 (Expand_Allocator_Expression): For an allocator expression whose nominal
12979 subtype is an unconstrained packed type, convert the expression to its
12980 actual constrained subtype.
12981 Implement warning for <= or >= where < or > not possible
12982 Fix to Vax_Float tests (too early in many routines, causing premature
12983 Vax_Float expansions.
12985 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
12986 to be used with packages and generic packages as well as with

12989 of pragma Suppress (All_Checks)
12990 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
12991 a string literal for precise control over warnings.

13001 Allow optional = after -gnatm
13002 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
13003 longer sets Elaboration_Checks.
13004 Code to set warning mode moved to Sem_Warn
13005 so that it can be shared by pragma processing.
13007 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
13010 * s-taprop-solaris.adb:
13011 Change some <= to =, to avoid new warning

13015 Fix obvious typo (Total_Errors_Detected <= 0 should be = 0)
13017 2005-11-14 Robert Dewar <dewar@adacore.com>
13019 * exp_vfpt.adb: Handle /= case
13020 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
13021 so that we do not get duplicate scaling for fixed point conversions.
13023 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
13025 2005-11-14 Matthew Gingell <gingell@adacore.com>
13027 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
13028 Increase default priority on Lynx from 15 to 17, and meet the Ada
13029 requirement that Default_Priority be ((Priority'First +
13030 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

13127 from a fat or thin pointer type and a constrained object type.
13128 (annotate_value): Handle BIT_AND_EXPR.
13129 (annotate_rep): Don't restrict the back annotation of inherited
13130 components to the type_annotate_only case.
13131 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
13132 we are not defining the type.
13133 <E_Record_Type>: Likewise.
13134 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
13135 to get advantage of the new maybe_stabilize_reference interface, to
13136 ensure that what we reference is indeed stabilized instead of relying
13137 on assumptions on what the stabilizer does.
13138 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
13139 type imported through a limited_with clause, use its non-limited view.
13140 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
13142 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
13143 of #if sections + explicit comparisons of convention identifiers.
13144 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
13145 before early-returning for certain types when code generation is
13147 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
13148 nullification of gnu_expr we do for objects with address clause and
13149 that we are not defining.
13150 (elaborate_expression_1): Do not create constants when creating
13151 variables needed by the debug info: the dwarf2 writer considers that
13152 CONST_DECLs is used only to represent enumeration constants, and emits
13154 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
13155 object with an address clause into an indirect reference, drop the
13156 initializing expression.
13158 (STACK_CHECK_BUILTIN): Delete.
13159 (STACK_CHECK_PROBE_INTERVAL): Likewise.

13167 if there is an actual subtype provided by the front-end, use that
13168 subtype to build an actual type with bounds template.
13169 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
13170 is provided by the front-end, use that subtype to compute the size of
13171 the deallocated object.
13172 (gnat_to_gnu): When adding a statement into an elaboration procedure,
13173 check for a potential violation of a No_Elaboration_Code restriction.
13174 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
13175 with extra arguments to control whether to recurse through non-values
13176 and to let the caller know if the stabilization has succeeded.

13178 maybe_stabilize, for common uses without restriction on lvalues and
13179 without need to check for the success indication.
13180 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
13181 pass false instead of 0 as the FORCE argument which is a bool.
13182 (Identifier_to_gnu): Remove checks ensuring that an renamed object
13183 attached to a renaming pointer has been properly stabilized, as no such
13184 object is attached otherwise.
13185 (call_to_gnu): Invoke create_var_decl to create the temporary when the
13186 function uses the "target pointer" return mechanism.
13187 Reinstate conversion of the actual to the type of the formal
13188 parameter before any other specific treatment based on the passing
13189 mechanism. This turns out to be necessary in order for PLACEHOLDER
13190 substitution to work properly when the latter type is unconstrained.
13192 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
13194 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
13195 with extra arguments to control whether to recurse through non-values
13196 and to let the caller know if the stabilization has succeeded.
13198 * utils2.c (gnat_build_constructor): Only sort the fields for possible
13199 static output of record constructor if all the components are constant.
13200 (gnat_build_constructor): For a record type, sort the list of field
13201 initializers in increasing bit position order.
13202 Factor common code to build a storage type for an unconstrained object
13203 from a fat or thin pointer type and a constrained object type.
13204 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
13205 types variants, and process special cases of VIEW_CONVERT expressions
13206 as their NOP_EXPR counterpart to ensure we get to the
13207 CORRESPONDING_VARs associated with CONST_DECls.
13208 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
13209 on the right-hand side.
13211 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
13213 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
13214 are converting back to its original type.
13215 (convert) <JM input>: Fallthrough regular conversion code instead of
13216 extracting the object if converting to a type variant.
13217 (create_var_decl): When a variable has an initializer requiring code
13218 generation and we are at the top level, check for a potential violation
13219 of a No_Elaboration_Code restriction.
13220 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
13221 SIZE and SIZE_UNIT which we need for later back-annotations.
13222 * utils.c: (convert) <STRING_CST>: Remove obsolete code.
13223 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
13224 is an unchecked union.
13225 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
13226 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
13227 main variant, just replace the VIEW_CONVERT_EXPR.

13363 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
13364 for task component, in the case of a limited aggregate. The enclosed

13410 Use Universal_Real instead of Long_Long_Float when we need a high
13411 precision float type for the generated code (prevents gratuitous
13412 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
13413 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
13414 'Terminated for task interface class-wide objects. Generate a call to
13415 the predefined dispatching routine used to retrieve the _task_id from

13444 (Expand_N_Return_Statement): When returning a mutable record, convert
13445 the return value into its actual subtype in order to help the backend
13446 to return the actual size instead of the maximum. This is another

13476 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

13496 attribute of the N_Free_Statement.
13497 Generate itype for classwide designated object in both cases of
13498 user-specified storage pool: specific and class-wide, not only in the
13500 Raise CE when trying to set a not null access type object to null.

13751 to diagnose attempts to use generic within its own declaration.
13753 2005-11-14 Ed Schonberg <schonberg@adacore.com>
13754 Javier Miranda <miranda@adacore.com>
13756 * sem_ch3.ads, sem_ch3.adb (Build_Discriminal): Add link to original
13758 (Build_Private_Derived_Type): The entity of the created full view of the
13759 derived type does not come from source. If after installing the private
13760 declarations of the parent scope the parent is still private, use its
13761 full view to construct the full declaration of the derived type.
13762 (Build_Derived_Record_Type): Relax the condition that controls the
13763 execution of the check that verifies that the partial view and
13764 the full view agree in the set of implemented interfaces. In
13765 addition, this test now only takes into account the progenitors.
13766 (Derive_Interface_Subprograms): No need to derive subprograms
13767 of ancestors that are interfaces.
13768 (Derive_Subprograms): Remove formal No_Predefined_Prims and the
13770 Change name Is_Package to Is_Package_Or_Generic_Package
13771 (Complete_Subprograms_Derivation): Handle the case in which the full
13772 view is a transitive derivation of the ancestor of the partial view.
13773 (Process_Full_View): Rename local subprogram Find_Interface_In_
13774 Descendant to Find_Ancestor_Interface to leave the code more clear.
13775 Remove wrong code that avoids the generation of an error message
13776 when the immediate ancestor of the partial view is an interface.
13777 In addition some minor reorganization of the code has been done to
13778 leave it more clear.
13779 (Analyze_Type_Declaration): If type has previous incomplete tagged
13780 partial view, inherit properly its primitive operations.
13781 (Collect_Interfaces): Make public, for analysis of formal
13783 (Analyze_Interface_Declaration): New procedure for use for regular and
13784 formal interface declarations.
13785 (Build_Derived_Record_Type): Add support for private types to the code
13786 that checks if a tagged type implements abstract interfaces.
13787 (Check_Aliased_Component_Type): The test applies in the spec of an
13789 (Access_Type_Declaration): Clean up declaration of malformed type
13790 declared as an access to its own classwide type, to prevent cascaded
13792 (Collect_Interfaces): For private extensions and for derived task types
13793 and derived protected types, the parent may be an interface that must
13794 be included in the interface list.
13795 (Access_Definition): If the designated type is an interface that may
13796 contain tasks, create Master_Id for it before analyzing the expression
13797 of the declaration, which may be an allocator.
13798 (Record_Type_Declaration): Set properly the interface kind, for use
13799 in allocators, the creation of master id's for task interfaces, etc.
13801 2005-11-14 Javier Miranda <miranda@adacore.com>
13802 Ed Schonberg <schonberg@adacore.com>
13804 * sem_ch6.adb (Check_Conformance): The null-exclusion feature can be
13805 omitted in case of stream attribute subprograms.
13806 (Check_Inline_Pragma): Handle Inline and Inline_Always pragmas that
13807 appear immediately after a subprogram body, when there is no previous
13808 subprogram declaration.
13809 Change name Is_Package to Is_Package_Or_Generic_Package
13810 (Process_Formals): A non null qualifier on a non null named access
13811 type is not an error, and is a warning only if Redundant_Constructs
13814 2005-11-14 Gary Dismukes <dismukes@adacore.com>
13815 Ed Schonberg <schonberg@adacore.com>
13817 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
13818 nested within Analyze_Package_Specification to install the private
13819 declarations and use clauses within each of the parent units of a
13820 package instance of a generic child package.
13821 (Analyze_Package_Specification): When entering a private part of a
13822 package associated with a generic instance or formal package, the
13823 private declarations of the parent must be installed (by calling new
13824 procedure Install_Parent_Private_Declarations).
13825 Change name Is_Package to Is_Package_Or_Generic_Package
13826 (Preserve_Full_Attributes): For a synchronized type, the corresponding
13827 record is absent in a generic context, which does not indicate a
13830 2005-11-14 Ed Schonberg <schonberg@adacore.com>
13832 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
13833 not try to rewrite a renamed stream attribute, because the operations
13834 on the type may not have been generated.
13835 Handle properly a renaming_as_body generated for a stream operation
13836 whose default is abstract because the object type itself is abstract.
13837 (Find_Type): If the type is incomplete and appears as the prefix of a
13838 'Class reference, it is tagged, and its list of primitive operations
13839 must be initialized properly.
13840 (Chain_Use_Clauses): When chaining the use clauses that appear in the
13841 private declaration of a parent unit, prior to compiling the private
13842 part of a child unit, find on the scope stack the proper parent entity
13843 on which to link the use clause.
13844 (Note_Redundant_Use): Emit a warning when a redundant use clause is
13846 (Analyze_Object_Renaming): An attribute reference is not a legal object
13847 if it is not a function call.

13850 Ed Schonberg <schonberg@adacore.com>
13852 * sem_eval.adb: Implement d.f flag
13853 (Subtype_Statically_Match): A generic actual type has unknown
13854 discriminants when the corresponding actual has a similar partial view.

13860 Robert Dewar <dewar@adacore.com>
13861 Thomas Quinot <quinot@adacore.com>
13863 * sem_res.adb (Resolve_Call): Provide a better error message whenever
13864 a procedure call is used as a select statement trigger and is not an
13865 entry renaming or a primitive of a limited interface.
13866 (Valid_Conversion): If the operand has a single interpretation do not
13867 remove address operations.
13868 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
13869 statement to inhibit warning.
13870 (Resolve_Unary_Op): Do not produce a warning when
13871 processing an expression of the form -(A mod B)
13872 Use Universal_Real instead of Long_Long_Float when we need a high
13873 precision float type for the generated code (prevents gratuitous
13874 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
13875 (Resolve_Concatenation_Arg): Improve error message when argument is an
13876 ambiguous call to a function that returns an array.
13877 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
13878 there is an implicit operator in the given scope if we are within an
13879 instance: legality check has been performed on the generic.
13880 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
13881 after resolving operand, to avoid false warnings on overloaded calls.
13883 2005-11-14 Ed Schonberg <schonberg@adacore.com>
13884 Javier Miranda <miranda@adacore.com>
13887 * sem_type.adb (Covers): In an inlined body, a composite type matches
13888 a private type whose full view is a composite type.
13889 (Interface_Present_In_Ancestor): Protect the frontend against
13890 previously detected errors to ensure that its compilation
13891 with assertions enabled gives the same output that its
13892 compilation without assertions.
13893 (Interface_Present_In_Ancestor): Add support for private types.
13894 Change name In_Actual to In_Generic_Actual (clean up)
13895 (Disambiguate): New predicate In_Actual, to recognize expressions that
13896 appear in the renaming declaration generated for generic actuals, and
13897 which must be resolved in the outer context.

13911 for a parameterless procedure.
13912 (Enter_Name): Recognize renaming declarations created for private
13913 component of a protected type within protected operations, so that

14467 generates the run-time check associated with null-excluding entities.
14468 (Expand_N_Return_Statement): Add tests to determine if the accessibility

14856 from object notation, the original node is unanalyzed and carries no
14857 semantic information, so that accessiblity checks must be performed on
14858 the type of the actual itself.
14859 (Expand_N_Subprogram_Declaration): Change last actual parameter for
14860 compatibility with Build_Protected_Sub_Specification.
14861 (Check_Overriding_Inherited_Interfaces): Add suport to handle
14862 overloaded primitives.
14863 (Register_Interface_DT_Entry): Use the new name of the formal
14864 the the calls to Expand_Interface_Thunk
14866 * exp_dbug.ads: Augment comments on encoding of protected types to
14867 include the generation of dispatching subprograms when the type
14868 implements at least one interface.
14870 * lib.ads: Extend information in Load_Stack to include whether a given
14871 load comes from a Limited_With_Clause.
14873 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
14874 whether a potential circularity is harmless, because it includes units
14875 loaded through a limited_with clause. Extends previous treatment which
14876 did not handle properly arbitrary combinations of limited and
14877 non-limited clauses.
14879 2005-09-01 Nicolas Setton <setton@adacore.com>
14881 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
14882 to be encoded as typ___XBLU_lowerbound__upperbound instead of
14883 typ___XB_lowerbound__upperbound.
14885 2005-09-01 Thomas Quinot <quinot@adacore.com>
14887 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
14888 dummy access formal for RACW/RAS TypeCode TSS.
14889 (Build_TypeCode_Call): Do not generate dummy null access actual for
14890 calls to the TypeCode TSS.
14892 2005-09-01 Ed Schonberg <schonberg@adacore.com>
14894 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
14895 fully qualified name, to distinguish instances with the same local name.
14897 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
14900 2005-09-01 Robert Dewar <dewar@adacore.com>
14902 * exp_pakd.adb (Create_Packed_Array_Type): Properly handle very large
14905 2005-09-01 Jerome Lambourg <lambourg@adacore.com>
14907 * g-expect.adb (Non_Blocking_Spawn): Initialize the filters field to
14908 (Free): New deallocation procedure for filter elements
14909 (Close): Deallocate any existing filter for the concerned connection
14911 2005-09-01 Laurent Pautet <pautet@adacore.com>
14913 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
14914 position set is provided, we compute one in order to reduce the maximum
14915 length of the keys. This computation first selects a character
14916 position between 1 and the minimum length of the keys in order to
14917 avoid reducing one of the keys to an empty string.
14918 (Initialize, Compute): When the ratio V to K is too low, the algorithm
14919 does not converge. The initialization procedure now comes with a
14920 maximum number of iterations such that when exceeded, an exception is
14921 raised in Compute. The user can initialize this ratio to another value
14923 Reformating and updated headers.
14925 2005-09-01 Javier Miranda <miranda@adacore.com>
14927 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
14928 that given an entity T creates and returns an Itype that duplicates the
14929 contents of T. The returned Itype has the null-exclusion
14930 attribute set to True, and its Etype attribute references T
14931 to keep the association between the two entities.
14932 Update copyright notice
14934 * sem_aggr.adb (Check_Can_Never_Be_Null,
14935 Aggregate_Constraint_Checks, Resolve_Aggregate,
14936 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
14938 * sem_ch5.adb (Analyze_Assignment): Code cleanup.
14940 2005-09-01 Gary Dismukes <dismukes@adacore.com>
14941 Robert Dewar <dewar@adacore.com>
14942 Hristian Kirtchev <kirtchev@adacore.com>
14944 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
14947 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
14949 Call Set_Result_Definition instead of Set_Subtype_Mark.
14950 (P_Subprogram_Specification): Add parsing of anonymous access result
14951 plus null exclusions. Call Set_Result_Definition instead of
14954 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
14955 (P_Access_Type_Definition): Add parsing for an anonymous access result
14956 subtype, plus parsing for null exclusions. Call Set_Result_Definition
14957 instead of Set_Subtype_Mark.
14959 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
14960 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
14961 (Result_Definition): New function for N_Function_Specifications.
14962 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
14963 N_Function_Specification.
14964 (Set_Null_Exclusion_Present): Allow this flag for
14965 N_Function_Specification.
14966 (Set_Result_Definition): New procedure for N_Function_Specifications.
14967 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
14968 and N_Function_Specification.
14970 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
14971 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
14972 Add support for LIMITED NEW for Ada 2005 AI-419
14973 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
14974 syntax for anonymous access results.
14975 Replace Subtype_Mark field by Result_Definition in
14976 N_Function_Specification and N_Access_Definition specs.
14977 Add Null_Exclusion_Present to spec of N_Function_Specification.
14978 (Result_Definition): New function for N_Function_Specification and
14979 N_Access_Function_Definition.
14980 (Set_Result_Definition): New procedure for N_Function_Specification and
14981 N_Access_Function_Definition.
14983 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
14984 Result_Definition for cases of N_Access_Function_Definition and
14985 N_Function_Specification.
14986 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
14988 2005-09-01 Vincent Celier <celier@adacore.com>
14990 * lib-writ.adb: Update Copyright notice
14991 (Write_With_Lines): On platforms where file names are case-insensitive,
14992 record the file names in lower case.
14993 (Write_ALI): For D lines, on platforms where file names are
14994 case-insensitive, record the file names in lower case.
14996 2005-09-01 Ed Schonberg <schonberg@adacore.com>
14997 Emmanuel Briot <briot@adacore.com>
14999 * lib-xref.adb (Output_Overridden_Op): Display information on
15000 overridden operation.
15002 * lib-xref.ads: Add documentation on overridden operations.
15004 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
15007 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
15008 overriding entity information.
15010 2005-09-01 Vincent Celier <celier@adacore.com>
15012 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
15013 including those that are inherited.
15015 2005-09-01 Robert Dewar <dewar@adacore.com>
15017 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
15019 * par-prag.adb: Implement new pragma Debug_Policy
15021 * sem_prag.adb Implement new pragma Debug_Policy
15022 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
15023 Component_Size attribute specification. Give warning for ignored pragma
15026 * snames.h, snames.ads, snames.adb: Introduce entries in
15027 Preset_Names for Name_Disp_Asynchronous_Select,
15028 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
15029 Name_Disp_Timed_Select.
15030 New pragma Debug_Policy
15032 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
15034 Switch -gnata also sets Debug_Pragmas_Enabled
15036 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
15037 handle an explicit -gnata when compiling predefined files.
15039 2005-09-01 Vincent Celier <celier@adacore.com>
15041 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
15042 directories of projects that have no Ada sources.
15044 2005-09-01 Robert Dewar <dewar@adacore.com>
15046 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
15047 (makes a difference for wide characters)
15049 * widechar.adb, widechar.ads:
15050 Add Wide_Char_Byte_Count feature to count chars vs bytes
15052 2005-09-01 Thomas Quinot <quinot@adacore.com>
15053 Ed Schonberg <schonberg@adacore.com>
15054 Robert Dewar <dewar@adacore.com>
15056 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
15057 'Address attribute reference with an overloaded prefix, use the
15058 location of the prefix (not the location of the attribute reference) as
15059 the error location.
15060 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
15061 a function renaming thereof, is a valid prefix for 'Size (where it is
15062 intepreted as a function call).
15063 (Statically_Denotes_Entity): New predicate to determine whether the
15064 prefix of an array attribute can be considered static.
15067 (Eval_Attr): Fix failure to evaluate Component_Size for
15068 unconstrained arrays (resulted in wrong value in packed case, since
15069 back end cannot handle this case)
15071 2005-09-01 Robert Dewar <dewar@adacore.com>
15073 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
15074 error msgs for most common cases.
15075 Use new errout insertion char < (conditional warning)
15077 2005-09-01 Javier Miranda <miranda@adacore.com>
15078 Ed Schonberg <schonberg@adacore.com>
15080 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
15081 become local to the whole package.
15082 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
15083 the package was already analyzed the new algorithm "replaces" the
15084 real entities by the shadow ones. This is required to ensure that
15085 the order of these entities in the homonym chains does not change;
15086 otherwise we can have undefined references at linking time because
15087 in case of conflicts the external name of the entities will have
15088 a suffix that depends on the order of the entities in the chain.
15089 (Remove_Limited_With_Clause): Complementary code that completes the
15090 new algorithm and replaces the shadow entities by the real ones.
15091 (Install_Limited_Withed_Unit): When unchaining entities before the
15092 installation of the shadow entities, only regular entities of the
15093 public part must be taken into account. This is required to
15094 keep this routine in synch with the work done by Remove_Limited_
15096 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
15097 even if unit is analyzed, because the analysis of the unit is
15098 idempotent in any case, and the limited view of the unit may have to
15099 be installed for proper visibility.
15100 (Expand_Limited_With_Clause): Even if the unit in the implicit
15101 with_clause has been analyzed already, a limited view of the package
15102 must be built for the current context, if it does not exist yet.
15104 2005-09-01 Ed Schonberg <schonberg@adacore.com>
15105 Javier Miranda <miranda@adacore.com>
15106 Gary Dismukes <dismukes@adacore.com>
15108 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
15109 defining entity for the instance body, make a new defining identifier
15110 rather than copying the entity of the spec, to prevent accidental
15111 sharing of the entity list.
15112 (Check_Private_View): When exchanging views of private types, build the
15113 list of exchanged views as a stack, to ensure that on exit the exchanges
15114 are undone in the proper order.
15115 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
15116 Restore the compilation environment in case of instantiation_error.
15117 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
15118 for an anonymous access result.
15119 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
15120 (Formal_Entity): Handle properly the case of a formal package that
15121 denotes a generic package renaming.
15123 2005-09-01 Thomas Quinot <quinot@adacore.com>
15125 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
15126 clause if the array aggregate is surrounded by parentheses.
15128 2005-09-01 Cyrille Comar <comar@adacore.com>
15129 Gary Dismukes <dismukes@adacore.com>
15130 Ed Schonberg <schonberg@adacore.com>
15131 Javier Miranda <miranda@adacore.com>
15133 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
15135 to check if a type is Constrained in cases related to code generation
15136 (rather than semantic checking) since otherwise we do not generate
15137 similar code for mutable private types depending if their
15138 discriminants are visible or not.
15139 (Check_Abstract_Overriding): Do not complain about failure to override
15140 the primitive operations used in dispatching selects since they will
15141 always be overriden at the freeze point of the type.
15142 (Access_Definition): Separate out handling for resetting the scope
15143 of an anonymous access function result type. Retrieve the scope
15144 of the associated function rather than using Current_Scope, which
15145 does not have a consistent value (depends on whether we're in the
15146 middle of analyzing formal parameters). Add ??? comment about
15147 finding a cleaner way to handle the special cases of scope setting.
15148 (Process_Incomplete_Dependents): A protected operation is never a
15149 dispatching operation (only its wrapper may be).
15150 (Build_Derived_Record_Type): In case of tagged private types that
15151 implement interfaces add derivation of predefined primitive
15153 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
15154 by two parameters that are used in case of derivation from abstract
15155 interface types: No_Predefined_Prims is used to avoid the derivation
15156 of predefined primitives from the interface, and Predefined
15157 Prims_Only is used to complete the derivation predefined primitives
15158 in case of private tagged types implementing interfaces.
15159 Fix typo in comments
15160 (Find_Interface_In_Descendant): Protect the frontend against
15161 wrong code with large circularity chains.
15162 (Is_Private_Overriding): Add support for entities overriding interface
15163 subprograms. The test failed because Entities associated with overriden
15164 interface subprograms are always marked as hidden (and used to build
15165 the secondary dispatch table); in this case the overriden entity is
15166 available through the field abstract_interface_alias (cf. override_
15167 dispatching_operation)
15168 (Access_Definition): Set the scope of the type to Current_Scope for the
15169 case of a function with an anonymous access result type.
15170 (Access_Subprogram_Declaration): Handle creation of the type entity for
15171 an access-to-function type with an anonymous access result.
15172 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
15173 in handling for N_Access_Function_Definition.
15174 (Analyze_Subtype_Declaration): Modify the text of error message.
15175 (Derived_Type_Declaration): Modify the text of error message.
15176 (Process_Subtype): Modify the text of error message plus cleanup
15177 of one redundant error message.
15178 (Analyze_Component_Declaration): Code cleanup.
15179 (Analyze_Object_Declaration): Code cleanup.
15180 (Analyze_Subtype_Declaration): Propagate the null-exclusion
15181 attribute in case of access types. Code cleanup.
15182 (Array_Type_Declaration): Code cleanup.
15183 (Process_Discriminants): Create the new null-excluding itype
15184 if required. Code cleanup.
15185 (Process_Subtype): Create the new null-excluding itype if
15186 required. Code cleanup.
15187 (Build_Derived_Record_Type): Code cleanup to avoid calling
15188 twice the subprogram derive_subprograms in case of private
15189 types that implement interfaces. In this particular case the
15190 subprogram Complete_Subprograms_Derivation already does the
15191 job associated with the second call.
15193 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
15194 conversion to the full view when generating an operation for a
15195 discriminant whose type may currently be private.
15197 2005-09-01 Ed Schonberg <schonberg@adacore.com>
15198 Javier Miranda <miranda@adacore.com>
15200 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
15201 V (Obj.F), the rewriting does not involve the indexed component, but
15202 only the selected component itself.
15203 Do not apply the transformation if the analyzed node is an actual of a
15204 call to another subprogram.
15205 (Complete_Object_Operation): Retain the entity of the
15206 dispatching operation in the selector of the rewritten node. The
15207 entity will be used in the expansion of dispatching selects.
15208 (Analyze_One_Call): Improve location of the error message associated
15210 (Analyze_Selected_Component): No need to resolve prefix when it is a
15211 function call, resolution is done when parent node is resolved, as
15213 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
15214 when attempting to resolve a call transformed from its object notation.
15215 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
15216 of the argument list for each interpretation of the operation.
15217 (Try_Object_Operation): The designated type of an access parameter may
15218 be an incomplete type obtained through a limited_with clause, in which
15219 case the primitive operations of the type are retrieved from its full
15221 (Analyze_Call): If this is an indirect call, and the return type of the
15222 access_to_subprogram is incomplete, use its full view if available.
15224 2005-09-01 Javier Miranda <miranda@adacore.com>
15225 Gary Dismukes <dismukes@adacore.com>
15227 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
15228 access types the null-exclusion and access-to-constant attributes must
15230 (Analyze_Return_Statement): When the result type is an anonymous access
15231 type, apply a conversion of the return expression to the access type
15232 to ensure that appropriate accessibility checks are performed.
15233 (Analyze_Return_Type): For the case of an anonymous access result type,
15234 generate the Itype and set Is_Local_Anonymous_Access on the type.
15235 Add ??? placeholder for check to disallow returning a limited object
15236 in Ada 2005 unless it's an aggregate or a result of a function call.
15237 Change calls from Subtype_Mark to Result_Definition.
15238 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
15239 Result_Definition in call to Make_Function_Specification.
15240 (Build_Body_To_Inline): Change Set_Subtype_Mark to
15241 Set_Result_Definition.
15242 (Make_Inequality_Operator): Change formal Subtype_Mark to
15243 Result_Definition in call to Make_Function_Specification.
15244 (Process_Formals): Create the new null-excluding itype if required.
15245 (New_Overloaded_Entity): For an entity overriding an interface primitive
15246 check if the entity also covers other abstract subprograms in the same
15247 scope. This is required to handle the general case, that is, overriding
15248 other interface primitives and overriding abstract subprograms inherited
15249 from some abstract ancestor type.
15250 (New_Overloaded_Entity): For an overriding entity that comes from
15251 source, note the operation that it overrides.
15252 (Check_Conformance, Type_Conformant): Addition of one new formal
15253 to skip controlling formals in the analysis. This is used to
15254 handle overloading of abstract interfaces.
15255 (Base_Types_Match): Add missing case for types imported from
15256 limited-with clauses
15257 (New_Overloaded_Entity): Add barrier to protect the use of
15258 the "alias" attribute.
15260 2005-09-01 Ed Schonberg <schonberg@adacore.com>
15262 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
15263 verify that the procedure and the entry are mode conformant.
15264 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
15265 as a different operator, which is often a cut-and-paste error.
15267 2005-09-01 Javier Miranda <miranda@adacore.com>
15268 Ed Schonberg <schonberg@adacore.com>
15270 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
15271 used in controlling parameters exclude null because it is necessary to
15272 read the tag to dispatch, and null has no tag.
15273 (Override_Dispatching_Operation): If the previous operation is inherited
15274 from an interface, it becomes hidden and does not participate in later
15277 2005-09-01 Javier Miranda <miranda@adacore.com>
15278 Ed Schonberg <schonberg@adacore.com>
15279 Gary Dismukes <dismukes@adacore.com>
15281 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
15282 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
15283 the expander will generate the corresponding run-time check to evaluate
15285 (Resolve_Call): Check for legal type of procedure name or prefix that
15286 appears as a trigger in a triggering alternative.
15287 (Valid_Conversion): If expression is ambiguous and the context involves
15288 an extension of System, remove System.Address interpretations.
15289 (Resolve_Qualified_Expression): Reject the case of a specific-type
15290 qualification applied to a class-wide argument. Enhance comment
15291 to explain checking of Original_Node.
15292 (Resolve_Type_Conversion): The location of the error message was not
15293 general enough to handle the general case and hence it has been removed.
15294 In addition, this patch improves the text of the message.
15295 (Resolve_Type_Conversion): Add missing support for access to interface
15297 (Resolve_Type_Conversion): If the target is a class-wide interface type,
15298 do not expand if the expression is the actual in a call, because proper
15299 expansion will take place when the call itself is expanded.
15300 (Resolve_Allocator): If the context is an unchecked conversion, the
15301 allocator inherits its storage pool, if any, from the target type of
15304 2005-09-01 Ed Schonberg <schonberg@adacore.com>
15305 Javier Miranda <miranda@adacore.com>
15307 * sem_type.adb (Add_One_Interp): If a candidate operation is an
15308 inherited interface operation that has an implementation, use the
15309 implementation to avoid spurious ambiguities.
15310 (Interface_Present_In_Ancestor): In case of concurrent types we can't
15311 use the Corresponding_Record_Typ attribute to look for the interface
15312 because it is set by the expander (and hence it is not always
15313 available). For this reason we traverse the list of interfaces
15314 (available in the parent of the concurrent type).
15315 (Interface_Present_In_Ancestor): Handle entities from the limited view
15317 2005-09-01 Ed Schonberg <schonberg@adacore.com>
15319 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
15320 from the list of required components.
15321 (Is_Controlling_Limited_Procedure): Determine whether an entity is a

16118 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
16119 longer protected objects. They have been replaced by lower-level
16120 suspension objects made up by a mutex and a condition variable (or
16121 their equivalent given a particular OS) plus some internal data to
16122 reflect the state of the suspension object.
16123 (Initialize, Finalize): Add this initialization procedure for
16124 Suspension_Object, which is a controlled type.

16153 until the state of the object is True. Program_Error is raised if
16154 another task is already waiting on that suspension object.
16155 (Initialize): Add this procedure for initializing the suspension
16156 object. It initializes the mutex and the condition variable which are
16157 used for synchronization and queuing, and it sets the internal state

16554 the generic that is created to represent the formal package.
16555 (Analyze_Package_Instantiation): Instantiate body immediately if the
16556 package is a predefined unit that contains inlined subprograms, and
16557 we are compiling for a Configurable_Run_Time.
16558 (Instantiate_Formal_Subprogram): Indicate that null default subprogram
16559 If the program has a null default, generate an empty body for it.
16561 * sem_ch6.adb, sem_ch9.adb (Analyze_Subprograms_Declaration): Update
16562 error message condition, null procedures are correctly detected now.
16563 (New_Overloaded_Entity): Bypass trivial overriding indicator check

16565 indicator is examined in Sem_Ch9 while analysing the subprogram
16567 (Check_Overriding_Indicator): Check consistency of overriding indicator
16568 on subprogram stubs as well.
16569 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
16571 (Analize_Subprogram_Specification): When analyzing a subprogram in which

16574 (Analyze_Subprogram_Body): Undo the previous work.
16575 (Analyze_Procedure_Call): If the call has the form Object.Op, the

16583 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
16584 access to subprograms must be recursive.
16585 (Is_Unchecked_Conversion): Improve the test that recognizes
16586 instantiations of Unchecked_Conversion, and allows them in bodies that
16587 are to be inlined by the front-end. When the body comes from an
16588 instantiation, a reference to Unchecked_Conversion will be an
16589 Expanded_Name, even though the body has not been analyzed yet.

16610 object or component (that is, when Is_Local_Anonymous_Access is true).
16611 Prevent the special checks for conversions of access discriminants in
16612 the case where the discriminant belongs to a nonlimited type, since
16613 such discriminants have their accessibility level defined in the same
16614 way as a normal component of an anonymous access type.
16615 (Resolve_Allocator): When an allocator's designated type is a class-wide
16616 type, check that the accessibility level of type given in the
16617 allocator's expression or subtype indication is not statically deeper
16618 than the level of the allocator's access type.

16633 Call to obsolescent subprogram is now considered to be a violation of
16634 pragma Restrictions (No_Obsolescent_Features).
16635 (Check_Direct_Boolean_Operator): If the boolean operation has been
16636 constant-folded, there is nothing to check.
16637 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
16638 check on possible violation of restriction No_Direct_Boolean_Operators
16639 until after expansion of operands, to prevent spurious errors when

16675 both bound checks, rather than a conjunction.
16676 (Insert_Valid_Check): If the expression is an actual that is an indexed
16677 component of a bit-packed array, force expansion of the packed element
16678 reference, because it is specifically inhibited elsewhere.

17596 (check dos line terminator).
17597 (Check_Line_Max_Length): New procedure, split off from the existing

17599 be properly recognized.
17601 * styleg.adb: Add ??? comment for line terminator reference
17603 * scng.adb (Check_End_Of_Line): Fix bug of -gnatyf being ignored

17644 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
17645 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
17646 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
17647 analyzed if expansion is disabled (which could otherwise cause spurious
17648 error messages if expansion has been disabled due to previous
17649 (unrelated) errors).
17651 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
17652 is disabled, the entity denoted by the argument is the access type
17653 itself, not an underlying record type, so there is no need to go back
17654 to the Corresponding_Remote_Type.
17656 2005-03-29 Gary Dismukes <dismukes@adacore.com>
17657 Robert Dewar <dewar@adacore.com>
17659 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
17660 expand a call to an instance of
17661 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the

17663 check is also generated, to ensure that the tag passed to the instance
17664 denotes a type in the class.
17665 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
17666 of Name_Generic_Dispatching_Constructor.
17668 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
17669 05 unit for AI-260-02).

17683 the case of renaming of stream attributes when the renaming denotes a
17684 generic formal subprogram association for an abstract formal subprogram.
17685 Check that the attribute is a primitive stream attribute (and not
17686 a class-wide stream attribute) and then rewrite the attribute name
17687 as the name of the appropriate compiler-generated stream primitive.
17689 2005-03-29 Robert Dewar <dewar@adacore.com>
17691 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

17699 itype whose parent is controlled and not yet frozen, do not create a
17700 freeze node for the itype if expansion is disabled.
17702 2005-03-29 Vincent Celier <celier@adacore.com>
17704 * make.adb (Gnatmake): Don't fail if the main project file is declared
17705 as having no Ada sources. Do not display message "no sources to
17706 compile" in quiet output.
17708 2005-03-29 Doug Rupp <rupp@adacore.com>
17710 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

17722 limited interface in Ada83 or Ada95 mode.
17724 2005-03-29 Robert Dewar <dewar@adacore.com>
17726 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
17727 rather than proceed ahead using a junk attribute name.
17729 2005-03-29 Vincent Celier <celier@adacore.com>
17731 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
17733 * prj-part.adb (Parse_Single_Project): Set the location of a project
17734 on its defining identifier, rather than on the reserved word "project".
17736 * prj-proc.adb (Expression): Adapt to the fact that default of external
17737 references may be string expressions, not always literal strings.
17738 (Recursive_Process): Set Display_Name equal to Name
17739 when Location is No_Location, that is when there is no actual file.
17740 Get the Display_Name of the project from the source, when it is not a
17742 (Process): Use the Display_Name in error messages
17744 * prj-strt.adb (External_Reference): Allow default to be string
17745 expressions, not only literal strings.
17747 2005-03-29 Vincent Celier <celier@adacore.com>

17755 forbid conversion of a local access-to-subprogram type to a remote one.
17757 * sem_util.adb (Wrong_Type): For a record type that is the expanded
17758 equivalent type for a remote access-to-subprogram type, go back to the
17759 original RAS entity when displaying an error message, so the casing is
17760 the original source casing.

17764 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
17767 2005-03-29 Ed Schonberg <schonberg@adacore.com>
17769 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
17770 subtype if code is being pre-analyzed, to prevent un-expanded
17771 references to protected formals, among others.
17772 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
17773 interpretation that can be a call, include the result of the call as a
17774 possible interpretation of the dereference.
17776 * sem_ch5.adb (Process_Bounds): Determine type of range by
17777 pre-analyzing a copy of the original range, and then analyze the range
17778 with the expected type.
17780 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
17781 with an overloaded prefix where not all interpretations yield an
17782 access to subprogram, do not rewrite node as a call.
17783 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
17784 the node as a call once the context identifies the interpretation of
17785 the prefix whose call yields the context type.
17786 (Valid_Conversion): For the case of a conversion between
17787 local access-to-subprogram types, check subtype conformance using
17788 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
17789 detailed error message.
17791 2005-03-29 Ed Schonberg <schonberg@adacore.com>
17793 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
17794 indicator, indicate that the formal can never be null.
17795 (Process_Formals): If a formal has a non_null indicator, insert the
17796 resulting subtype immediately before the enclosing subprogram decl,
17797 and not at the beginning of the corresponding declarative part, to
17798 prevent access before elaboration (Ada2005).

17907 to install the visible declarations of the enclosing scope of a
17908 record_type_with_private to establish the proper visibility before
17909 freezing the entity and related subprograms.

17919 (Check_Stream_Attribute): Move the code for 13.13.2(9/1) enforcement
17920 into a new Check_Attr subprogram, in order to provide a more
17921 explanatory error message (including the name of the missing attribute).
17922 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
17923 subprogram determines whether a default implementation exists for a
17924 given stream attribute.
17925 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
17926 Determine whether to generate a default implementation for each stream
17927 attribute separately, as this depends on the specific attribute.
17929 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
17930 limited extension where a stream attribute is missing for a limited
17931 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

18445 syntax rule of Ada 2005 interfaces
18446 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
18447 messages by the correct RENAMES (quotes removed).
18449 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
18450 attribute First_Tag_Component.

18462 (Task_Body_Procedure): Removed.
18463 (Set_Task_Body_Procedure): Removed.
18464 These subprogram have been removed because the attribute
18465 Task_Body_Procedure has been moved to the corresponding task type
18466 or task subtype entity to leave a field free to store the list
18467 of interfaces implemented by a task (for AI-345)
18468 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
18469 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
18470 expression flag Do_Range_Check
18471 (Exception_Junk): Change to Flag7 to accomodate above change
18472 (Box_Present, Default_Name, Specification, Set_Box_Present,
18473 Set_Default_Name, Set_Specification): Expand the expression
18474 "X in N_Formal_Subprogram_Declaration" into the corresponding
18475 two comparisons. Required to use the csinfo tool.

18478 "with string" given.
18480 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
18483 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
18486 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
18487 attribute Task_Body_Procedure rather than the old semantic field that
18488 was available in the task_type_declaration node.
18490 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
18491 interface type definitions.
18492 (P_Formal_Derived_Type_Definition): Modified to handle the list of
18495 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
18496 task type declaration.

18498 protected type declaration.
18500 2005-03-15 Doug Rupp <rupp@adacore.com>
18501 Vincent Celier <celier@adacore.com>
18503 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
18504 (Gen_Output_File_C): Likewise.
18505 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
18507 2005-03-15 Thomas Quinot <quinot@adacore.com>
18509 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
18510 is an N_Raise_Constraint_Error node, create a new copy of it without
18511 going through a call to Duplicate_Subexpr.
18513 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
18514 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

18516 Ed Schonberg <schonberg@adacore.com>
18522 * decl.c (gnat_to_gnu_field): Reject aliased components with a
18523 representation clause that prescribes a size not equal to the rounded
18524 size of their types.
18525 (gnat_to_gnu_entity, case E_Component): Always look at
18526 Original_Record_Component if Present and not the entity.

18530 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
18531 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
18532 expression to the type of the object when the object is constant.
18533 Reverse defer_debug_incomplete_list before traversing it, so that trees
18534 are processed in the order at which they were added to the list. This
18535 order is important when using the stabs debug format.
18536 If we are deferring the output of debug information, also defer this
18537 output for a function return type.
18538 When adding fields to a record, prevent emitting debug information
18539 for incomplete records, emit the information only when the record is
18541 (components_to_record): New parameter defer_debug.
18542 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
18543 (gnat_to_gnu_field_decl): New function.
18544 (substitution_list, annotate_rep): Call it.
18545 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
18546 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
18547 No longer update discriminants to not be a COMPONENT_REF.
18548 (copy_alias_set): Strip padding from input type; also handle
18549 unconstrained arrays properly.
18551 * gigi.h (write_record_type_debug_info): New function.
18552 Convert to use ANSI-style prototypes. Remove unused
18553 declarations for emit_stack_check, elab_all_gnat and
18554 set_second_error_entity.
18555 (gnat_to_gnu_field_decl): New decl.
18557 * utils.c (write_record_type_debug_info): New function.

18560 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
18561 (update_pointer_to): Fix pasto.
18562 (convert) <UNION_TYPE>: Accept slight type variations when
18563 converting to an unchecked union type.
18565 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
18566 replace the N_Freeze_Entity with a null statement.
18568 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
18569 within a constrained subcomponent of an enclosing record, place the
18570 freeze nodes in the scope stack entry for the enclosing record.
18571 (Undelay_Type): New Subprogram.
18572 (Set_Small_Size): Pass T, the type to modify; all callers changed.
18573 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
18574 within records; allow them to have freeze nodes if their base types
18577 * exp_util.adb (Remove_Side_Effects): Properly test for
18578 Expansion_Delayed and handle case when it's inside an
18579 N_Qualified_Expression.
18581 * sem_ch3.adb (Derived_Type_Declaration): New predicate
18582 Comes_From_Generic, to recognize accurately that the parent type in a
18583 derived type declaration can be traced back to a formal type, because
18584 it is one or is derived from one, or because its completion is derived
18586 (Constrain_Component_Type): If component comes from source and has no
18587 explicit constraint, no need to constrain in in a subtype of the
18589 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
18590 Minor change to propagate Is_Ada_2005 flag
18592 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
18593 Expansion_Delayed is False.
18594 (assoc_to_constructor): Ignore fields that have a
18595 Corresponding_Discriminant.
18596 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
18597 function returns "by target", dereference the target pointer using the
18598 type of the actual return value.
18599 <all>: Be prepared for a null gnu_result.
18600 (processed_inline_subprograms): Check flag_really_no_inline
18601 instead of flag_no_inline.

18608 Ed Schonberg <schonberg@adacore.com>
18609 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
18611 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
18612 Must_Be_Byte_Aligned for cases where we do not need to use a
18613 System.Pack_nn unit.
18615 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
18617 Needed now that we do some processing for IN parameters as well. This
18618 may well fix some unrelated errors.
18619 (Expand_Call): Handle case of unaligned objects (in particular those
18620 that come from packed arrays).
18621 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
18622 renamed entity is an inherited operation, re-expand the call using the
18623 original operation, which is the one to call.
18624 Detect attempt to inline parameterless recursive subprogram.
18625 (Represented_As_Scalar): Fix to work properly with private types
18626 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
18627 accurate estimate. Yields True in far fewer cases than before,
18628 improving the quality of code that depends on this test.
18630 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
18631 over both visible and private declarations to remove them from tree,
18632 and mark subprograms declared in package as eliminated, to prevent
18633 spurious use in subsequent compilation of generic units in the context.
18635 * exp_util.ads: Minor cleanup in variable names
18637 * sem_eval.ads, sem_eval.adb: Minor reformatting
18638 (Compile_Time_Known_Bounds): New function
18640 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18642 * exp_ch7.adb (Convert_View): Use base types of underlying types when
18643 determining whether an unchecked conversion is needed for the argument
18644 of an initialization call.
18646 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18648 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
18649 that appears in the instantiation rather than the internal subtype
18650 generated in the wrapper package, to avoid anomalies in gigi when the
18651 target is derived from a private type whose full view is an access type.
18653 2005-03-15 Robert Dewar <dewar@adacore.com>
18655 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
18657 Add documentation to replace the use of this flag
18658 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
18661 2005-03-15 Thomas Quinot <quinot@adacore.com>
18663 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
18664 here from exp_attr so it can be shared between exp_attr and exp_dist.
18665 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
18666 all TSS names, not a subset thereof, and the previous name introduced
18667 an unnecessarily confusion that a distinction might exist between
18668 "OK" TSS names and some "not OK" TSS names.
18670 2005-03-15 Doug Rupp <rupp@adacore.com>
18672 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
18675 2005-03-15 Pascal Obry <obry@adacore.com>
18676 Eric Botcazou <ebotcazou@adacore.com>
18680 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
18681 when IN_RTS. This is to work around a bootstrap path problem.
18683 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
18684 table and pass it to __gnat_install_SEH_handler().
18685 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
18687 * lang.opt: Fix specification of -fRTS=.
18689 2005-03-15 Doug Rupp <rupp@adacore.com>
18690 Bernard Banner <banner@adacore.com>
18691 Vincent Celier <celier@adacore.com>
18692 Arnaud Charlet <charlet@adacore.com>
18695 This change works fine when gnatlib is built from the gcc directory,
18696 but does not work when using the libada Makefile, since GCC_FOR_TARGET
18697 is not passed to ada/Makefile.in, so more work is needed by a
18698 Makefile/configure expert.
18700 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
18701 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
18702 Setup gnatlink switch -M for x86_64 linux, as it is already setup
18704 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
18705 Run ranlib on libgccprefix.a
18706 Define PREFIX_OBJS for Darwin, to build libgccprefix.
18707 (ADA_INCLUDE_SRCS): Split Ada packages.
18709 2005-03-15 Robert Dewar <dewar@adacore.com>
18711 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
18713 * impunit.adb: Add GNAT.UTF_32
18715 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
18717 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
18718 now uses GNAT.UTF_32).
18720 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
18721 capabilities for categorizing characters using Unicode categories
18723 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18725 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
18726 instantiation that has been rewritten as a package body, retrieve spec
18727 to generate proper name for implicit_with_clause.
18728 (Install_Parents): Recognize a parent that is an instantiation but has
18729 been rewritten as a package declaration during analysis.
18731 2005-03-15 Javier Miranda <miranda@adacore.com>
18732 Ed Schonberg <schonberg@adacore.com>
18734 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
18735 parameter reported some error we immediately return. This improves the
18736 behaviour of the frontend in case of errors.
18737 (Install_Parent, Remove_Parent): Introduce new flag
18738 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
18739 ancestor of a generic child unit, when the child is being instantiated.
18740 (Inline_Instance_Body): If we are compiling the private
18741 part or the body of a child unit, restore the proper visibility of the
18742 parents after compiling the instance body.
18744 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18745 Javier Miranda <miranda@adacore.com>
18748 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
18749 of a private type, in which case it is underlying_type that denotes
18750 the proper task. Also modified to use the new entity attribute
18751 that is directly available in the task type and task subtype entities
18752 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
18753 arrays when other dimensions than the first are constrained by
18754 discriminants of an enclosing record.
18755 (Insert_Explicit_Dereference): If the prefix is an indexed component or
18756 a combination of indexed and selected components, find ultimate entity
18757 and generate the appropriate reference for it, to suppress spurious
18759 (Note_Possible_Modification): If an entity name has no entity, return.
18760 (Is_Variable): A function call never denotes a variable.
18761 (Requires_Transient_Scope): For record types, recurse only on
18762 components, not on internal subtypes that may have been generated for
18763 constrained components.
18765 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18767 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
18768 Eliminated as candidates for resolution. Both efficient, and avoids
18769 anomalies with operators declared in deleted code.
18770 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
18771 expansion is disabled (as when compiling a generic) to prevent spurious
18772 warnings on prefixes of selected components.
18774 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18776 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
18777 attached to a list before checking whether it appears in the private
18778 declarations of the current package.
18779 (Make_Inequality_Operator): Insert declaration in proper declarative
18780 list rather than just setting the Parent field, so that
18781 Is_Private_Declaration can handle it properly.
18783 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18785 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
18786 a renaming a body, check that the renamed subprogram in not intrinsic.
18787 (Find_Direct_Name): If several use_visible entities hide
18788 each other, and the context is a predefined file compiled through
18789 rtsfind, keep only the entity that comes from a predefined file.
18791 2005-03-15 Geert Bosch <bosch@adacore.com>
18793 * s-fatgen.adb (Valid): Extend special exceptions to account for long
18794 long float padding to also cover AMD64 and IA64.
18796 2005-03-15 Gary Dismukes <dismukes@adacore.com>
18798 * s-imgwch.adb: Add with and use of Interfaces.
18799 (Img_Wide_Character): Change type of Val to Unsigned_16.
18800 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
18802 2005-03-15 Matthew Gingell <gingell@adacore.com>
18804 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
18806 2005-03-15 Robert Dewar <dewar@adacore.com>

18810 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
18812 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
18814 2005-03-15 Robert Dewar <dewar@adacore.com>

18838 procedures in the bug boxes for various GNAT builds.
18840 2005-03-15 Vincent Celier <celier@adacore.com>
18842 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

18847 Cyrille Comar <comar@adacore.com>
18848 Sergey Rybin <rybin@adacore.com>
18850 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
18851 too specific and long-winded to be appropriate for the GNAT User's
18853 Warn about use of GCC switches not documented in the GNAT User's Guide,
18854 as these may cause generated code to not conform to Ada semantics.
18855 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
18856 Add documentation for -gnat95 and -gnat05 switches
18857 Remove paragraph documenting obsolete way to refer to third party
18859 Add a few references to Ada_05 that were missing.
18860 Update documentation on -gnatZ/-gnatL.
18861 Document limitation when using -m64 under Solaris.
18862 Change the "Name Casing" subsection of the pretty-printer section

18907 2005-02-12 Richard Henderson <rth@redhat.com>
18909 * utils.c (gnat_type_for_mode): Return NULL for COMPLEX modes;

19308 a tag-indeterminate function call whose type is an ancestor of the

19394 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
19395 side-effects as if it were a constant; also make SAVE_EXPR to protect
19397 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
19399 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.

19411 * utils.c (gnat_pushdecl): Set TREE_NO_WARNING.
19413 2005-02-09 Ed Schonberg <schonberg@adacore.com>
19415 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
19416 component of an array of arrays in an assignment context, and the
19417 aggregate has component associations that require sliding on
19418 assignment, force reanalysis of the aggregate to generate a temporary
19419 before the assignment.
19420 (Must_Slide): Make global to the package, for use in Gen_Assign.
19422 2005-02-09 Ed Schonberg <schonberg@adacore.com>
19424 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
19425 unchecked union with no inferable discriminants, return a
19426 Raise_Program_Error node, rather than inserting it at the point the
19428 (Expand_Record_Equality, Component_Equality): Handle properly the case
19429 where some subcomponent is an unchecked union whose generated equality
19430 code raises program error.

19438 Arnaud Charlet <charlet@adacore.com>
19440 * init.c (__gnat_initialize): Add a new parameter eh which contains the
19441 address of the exception registration. The Win32 version of this
19442 routine calls __gnat_install_SEH_handler() to initialize the SEH
19443 (Structured Exception Handling) handler.
19444 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
19445 SEH (Structured Exception Handling) now.
19446 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
19447 (__gnat_initialize for ppc-vxworks): Adjust comments and the
19448 preprocessor condition protecting the call to the extra eh setup
19449 subprogram, which is only available for the ppc target.
19450 (__gnat_clear_exception_count): replaced reference to
19451 variable taskIdCurrent by call to taskIdSelf(), cleaner.
19453 * seh_init.c: New file.
19455 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
19456 (GNATBIND_OBJS): Idem.
19458 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
19459 routine takes a new parameter (a pointer to the exception registration
19460 for the SEH (Structured Exception Handling) support.
19462 * raise.h: (__gnat_install_SEH_handler): New prototype.
19463 Update copyright notice.
19465 * s-tassta.adb (Task_Wrapper): Declare the exception registration
19466 record and initialize it by calling __gnat_install_SEH_handler.
19468 2005-02-09 Vincent Celier <celier@adacore.com>
19470 * make.adb (Gnatmake): Do not fail when the main project has no object

19476 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
19477 [VMS]: Add translations for g-enblsp.adb.
19479 * s-asthan-vms.adb: Removed.
19480 * s-asthan-vms-alpha.adb: Added.

19491 -shared-libgcc is now used by default on some systems (e.g. linux with
19493 Remove references to Makefile.prolog/generic, no longer used.
19495 2005-02-09 Vincent Celier <celier@adacore.com>
19497 * prj-makr.adb (Process_Directory): Put file name in canonical case
19498 before matching against the patterns.
19499 If gnatname has been invoked as <prefix>-gnatname
19500 then invoke the compiler as <prefix>-gcc, not just "gcc".
19502 2005-02-09 Ed Schonberg <schonberg@adacore.com>
19504 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
19505 with expansion disabled. The actual subtype is needed among other
19506 places when the selected component appears in the context of a loop
19507 bound, and denotes a packed array.
19508 (Operator_Check): Always use the first subtype in the
19509 error message, to avoid the appearance of internal base types.
19510 (Transform_Object_Operation): Copy each actual in full
19511 to the parameter associations of the constructed call, rather than
19512 using the shallow copy mechanism of New_Copy_List. This ensures that
19513 the chaining of named associations is done properly.
19514 (Complete_Object_Operation): Rewrite node, rather than
19515 replacing it, so that we can trace back to the original selected
19518 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
19519 and calls that use object notation, if the called function is not
19520 declared in a withed unit, place the elaboration constraint on the
19521 unit in the context that makes the function accessible.
19522 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
19523 imposes an elaboration constraint between two packages.
19525 2005-02-09 Ed Schonberg <schonberg@adacore.com>
19527 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
19528 views of a private type after handling its private dependents, to
19529 maintain proper stack discipline between entry and exit from the
19532 2005-02-09 Cyrille Comar <comar@adacore.com>
19534 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

19539 * s-tporft.adb (Register_Foreign_Thread): Initialize Task_Image[_Len]
19540 fields for foreign threads.

19552 * xr_tabls.ads: Add ??? comment for missing overall comment
19554 * xsinfo.adb: Make default file name be sinfo.h, since this is what
19555 we now use by default.
19557 * xsnames.adb: Adjust end of file test to look for five space followed
19558 by '#' instead of six spaces. The format of xsnames.adb was modified
19559 in the last update.
19561 * a-numeri.ads: Add reference to AI-388 for greek letter pi
19564 * clean.adb: Minor reformatting.
19566 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
19567 gnatname.adb: Minor reformatting

19570 * csets.adb: Eliminate obsolete comment
19572 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
19575 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
19577 2005-02-09 Sergey Rybin <rybin@adacore.com>
19579 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
19580 the difference between compact and incompact layout and add the record
19581 representation clause to the example illustrating different layouts.
19582 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
19583 component clauses").
19585 2005-02-09 Florian Villoing <villoing@adacore.com>
19587 * gnat_ugn.texi: Fix typos.
19588 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

19635 * exp_util.ads: Minor correction in comment.
19637 2005-02-09 Arnaud Charlet <charlet@adacore.com>
19639 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
19640 since this procedure is now too complex to be worth inlining.

19939 variable Dynamic_Async.
19940 (Build_Subprogram_Receiving_Stubs): Make PCS-specific

20318 access value, if appropriate.
20320 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
20321 emitting 'assigned but never read' warning on a variable on the basis

20385 compile-time warning.
20387 2004-12-07 Robert Dewar <dewar@adacore.com>
20389 * g-regpat.adb: (Match): Change a misuse of or to or else
20391 2004-12-07 Ed Schonberg <schonberg@adacore.com>
20394 (Generate_Reference): Handle properly a reference to an entry formal,
20395 when an accept statement has a pragma Unreferenced for it.
20397 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
20398 and the Has_Pragma_Unreferenced flag for each formal before analyzing
20399 the body, to ensure that warnings are properly emitted for each accept
20400 statement of a given task entry.
20402 2004-12-07 Vasiliy Fofanov <fofanov@adacore.com>
20404 * Makefile.in: Add support for foreign threads on VMS.

20422 (Remove_Next_Debug): Same fix
20424 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
20425 maintain back pointers now, though we did not used to, and comments
20427 (Prepend): Remove pragma Inline.
20428 (Remove_Next): Same cleanup
20430 2004-12-07 Thomas Quinot <quinot@adacore.com>
20432 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
20433 used to record an implicit dereference as a read operation on its
20434 prefix when operating under -gnatc. Necessary to avoid spurious
20435 'variable assigned but never read' warnings in that mode.
20436 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
20437 is a non-overloaded implicit dereference, call the above subprogram to
20438 ensure proper recording of references.
20440 2004-12-07 Gary Dismukes <dismukes@adacore.com>
20442 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
20443 to be resolved later as part of Analyze_Iteration_Scheme's call to
20446 2004-12-07 Ed Schonberg <schonberg@adacore.com>
20448 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

20484 Files" with the new tool and package names.
20485 Reformatting to suppress most of the warnings for line too long
20486 Document the new section "Project Search Path:" in the output of
20488 Add gnatmetric section
20490 2004-12-07 Vincent Celier <celier@adacore.com>
20492 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
20493 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
20494 and -eit to -ept. Added qualifier
20495 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
20497 2004-11-27 Andreas Schwab <schwab@suse.de>
20499 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
20501 2004-11-25 Arnaud Charlet <charlet@adacore.com>
20503 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
20504 internal implementation unit GNAT.Sockets.Thin,
20505 as their usage for sockets is non-portable (using the read and write
20506 functions from the system runtime library is fine on UNIX but won't
20507 work under Windows).
20509 * mingw32.h: Update copyright notice.
20511 2004-11-25 Arnaud Charlet <charlet@adacore.com>
20513 * ada-tree.h: Minor reformatting of previous change to avoid lines
20514 longer than 79 characters.

20539 * adaint.h, adaint.c
20540 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
20542 Add also a cast to kill another warning.
20543 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags

20545 always using the NORMAL_PRIORITY_CLASS.
20546 (__gnat_dup): New function.
20547 (__gnat_dup2): New function.
20548 (__gnat_is_symbolic_link): Enable the effective body of this
20549 function when __APPLE__ is defined.
20551 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
20554 2004-11-18 Olivier Hainque <hainque@adacore.com>
20556 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
20557 address of which may be used to represent "others" and "all others"
20558 choices in exception tables, instead of the current harcoded
20559 (void *)0 and (void *)1.
20560 (Setup_Exception): Do nothing in the GNAT SJLJ case.
20562 * gigi.h (others_decl, all_others_decl): New decls representing the
20563 new Others_Value and All_Others_Value objects.
20564 (struct attrib): Rename "arg" component as "args", since GCC expects a
20565 list of arguments in there.
20567 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
20568 corresponding objects exported by a-exexpr, instead of hardcoded dummy
20571 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
20572 others_decl and all_others_decl instead of hardcoded dummy addresses
20573 to represent "others" and "all others" choices, which is cleaner and
20574 more flexible with respect to the possible eh pointer encoding policies.
20576 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
20577 (process_attributes): Account for the naming change of the "args"
20578 attribute list entry component.
20580 * decl.c (build_attr_list): Rename into prepend_attributes to allow
20581 cumulating attributes for different entities into a single list.
20582 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
20583 attributes for the current entity and propagate first subtype
20584 attributes to other subtypes.
20585 <E_Procedure>: Attribute arguments are attr->args and not
20586 attr->arg any more.
20587 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
20588 argument provided, as this is what GCC expects. Use NULL_TREE instead
20591 2004-11-18 Robert Dewar <dewar@adacore.com>
20593 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
20594 Minor reformatting througout (including new function specs)
20595 Add ??? comments asking for clarification.
20597 2004-11-18 Thomas Quinot <quinot@adacore.com>
20599 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
20600 incomplete duplicate implementation of this subprogram from butil.
20602 2004-11-18 Thomas Quinot <quinot@adacore.com>

20605 procedures factors the common processing for building an RPC receiver
20606 for an RCI package or an RACW type.
20607 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
20608 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
20609 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
20611 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
20613 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
20615 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
20616 distribution subprogram identifiers that are either subprogram numbers

20619 string distribution identifiers assigned to a given subprogram.
20620 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
20621 (Add_RAS_Dereference_TSS): Add comments.
20622 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
20623 is not referenced yet because it will be used by the PolyORB DSA
20625 (Insert_Partition_Check): Remove fossile code.
20626 (First_RCI_Subprogram_Id): Document this constant.
20627 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
20629 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
20630 replaced with calls to Get_Library_Unit_Name_String. Previously there
20631 were several instances of the same code in different locations in the
20632 compiler; this checkin completes the replacement of all of these
20633 instances with calls to a common subprogram.
20634 Minor reformatting.
20636 * sem_dist.adb: Remove comment noting that RPC receiver generation
20637 should be disabled for RACWs that implement RASs.
20638 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.

20642 qualified name of a library unit into the name buffer.
20643 (Note_Possible_Modification): Generate a reference only
20644 if the context comes from source.
20646 * snames.ads (PCS_Names): New subtype corresponding to names of
20647 supported implementations of the Partition Communication Subsystem
20648 (PCS) (i.e. the runtime library support modules for the distributed

20662 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
20663 (Expand_Pragma_Psect_Object): New procedure
20664 These procedures contain the revised and cleaned up processing for
20665 these two pragmas. This processing was formerly in Sem_Prag, but
20666 is more appropriately moved here. The cleanup involves making sure
20667 that the pragmas are properly attached to the tree, and that no
20668 nodes are improperly shared.
20670 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
20671 pragmas to Exp_Prag, which is more appropriate.
20672 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
20673 check for duplicates Remove use of Is_Psected flag, no longer needed.
20674 Use new Make_String_Literal function with string.
20676 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
20677 that are functions return universal values, that have to be converted
20678 to the context type.
20679 Use new Make_String_Literal function with string.
20680 (Get_Stream_Convert_Pragma): New function, replaces the use of
20681 Get_Rep_Pragma, which had to be kludged to work in this case.
20683 * freeze.adb: Use new Has_Rep_Pragma function
20685 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
20686 function with string.
20687 Use new Has_Rep_Pragma function.
20689 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
20692 2004-11-18 Robert Dewar <dewar@adacore.com>
20694 * errout.ads, errout.adb: (First_Sloc): New function
20696 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
20697 check (-gnatyx) instead of being included as a redundant construct
20700 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
20701 Style_Check_Order_Subprograms.
20703 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
20704 stylesw.adb: Add Style_Check_Xtra_Parens
20706 * usage.adb: Add line for -gnatyx (check extra parens)
20708 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
20710 2004-11-18 Ed Schonberg <schonberg@adacore.com>
20711 Robert Dewar <dewar@adacore.com>
20713 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
20714 discriminant of a constrained subtype, analyze the copy of the
20715 corresponding constraint, because in some cases it may be only
20716 partially analyzed.
20717 Removes long-lived ??? comments.
20719 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
20720 handled controlled or secondary-stack expressions within the
20721 iteration_scheme of a loop.
20723 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
20724 bounds that may contain functions calls, to prevent memory leaks when
20725 the bound contains a call to a function that uses the secondary stack.
20726 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
20727 generate temporaries for loop bounds that might contain function calls
20728 that require secondary stack and/or finalization actions.
20730 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
20731 selected component and the selector is overloadable (not just a
20732 function) treat as function call, Analyze_Call will disambiguate if
20734 (Analyze_Selected_Component): Do not generate an actual subtype for the
20735 selected component if expansion is disabled. The actual subtype is only
20736 needed for constraint checks.
20737 (Analyze_Allocator): If restriction No_Streams is set, then do
20738 not permit objects to be declared of a stream type, or of a
20739 composite type containing a stream.
20741 * restrict.ads: Remove the a-stream entry from Unit_Array, since
20742 No_Streams no longer prohibits with'ing this package.
20744 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
20745 discriminants, but the parent base has unknown discriminants, there is
20746 no discriminant constraint to inherit. Such a discrepancy can arise
20747 when the actual for a formal type with unknown discriminants is a
20748 similar private type whose full view has discriminants.
20749 (Analyze_Object_Declaration): If restriction No_Streams is set, then
20750 do not permit objects to be declared of a stream type, or of a
20751 composite type containing a stream.
20753 2004-11-18 Ed Schonberg <schonberg@adacore.com>
20755 * exp_dbug.ads: Update documentation to reflect simpler encoding for
20756 protected operations.
20758 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
20759 generated name, it complicates decoding in gdb and hinders debugging
20760 of protected operations.
20761 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
20762 flag for the protected entry barrier function.
20763 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
20764 flag for the protected entry function.

20770 * Makefile.in: Inform the value of the variable GMEM_LIB in the
20771 Darwin-specific section.
20773 * lang-specs.h: Change the placement of the %1 marker.
20774 Works around the fact that gcc adds -fPIC by default under Darwin.
20776 2004-11-18 Ed Schonberg <schonberg@adacore.com>
20778 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
20779 type of the object with the packed array type, set the Analyzed flag
20780 on the object if it is an entity or simple indexed component, to avoid
20781 spurious type errors.
20783 2004-11-18 Gary Dismukes <dismukes@adacore.com>
20785 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
20786 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
20787 separate line from the version message.
20789 2004-11-18 Ed Falis <falis@adacore.com>
20791 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
20793 (init_float): Eliminate initialization of floating point status for
20794 AE653. The instructions have no effect for vThreads.
20796 2004-11-18 Vincent Celier <celier@adacore.com>
20798 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
20799 gnatbind is invoked with -shared.
20801 2004-11-18 Jose Ruiz <ruiz@adacore.com>
20803 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
20804 for Detect_Blocking which is redundant with the check done within the
20805 procedure Protected_Single_Entry_Call.
20806 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
20807 Detect_Blocking which is redundant with the check done within the
20808 procedure Protected_Single_Entry_Call.
20810 2004-11-18 Vincent Celier <celier@adacore.com>
20812 * makegpr.adb (Compile): Put the compiling switches (in package
20813 Compiler and on the command line) immediately after "-c", instead of
20814 at the end of the command line invocation of the compiler, when
20815 compiling a non-Ada file.
20816 (Build_Global_Archive): When there is no need to rebuild the archive,
20817 set Global_Archive_Exists, so that the archive is passed to the linker
20820 2004-11-18 Robert Dewar <dewar@adacore.com>
20821 Sergey Rybin <rybin@adacore.com>
20824 Remove extra paren check from list of checks for redundant constructs
20825 Add documentation of new -gnatyx style check (check extra parens)
20826 Remove paragraph about gnatelim debug options.
20828 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
20829 objects rather than forbidding dependencies on the package Ada.Streams.
20831 * sinfo.ads: Add ??? note that we should document pragmas passed to
20834 * g-expect.ads: Fix a few typos in the comments.
20836 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
20838 * misc.c (gnat_handle_option): Use %< and %> for quoting in
20841 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
20843 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
20845 2004-11-07 Andreas Schwab <schwab@suse.de>
20847 * Makefile.in (install-gnatlib): Remove spurious hyphen.
20849 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
20852 * Makefile.in (darwin): Set soext to .dylib.
20854 2004-10-26 Vincent Celier <celier@gnat.com>
20855 Thomas Quinot <quinot@act-europe.fr>
20857 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
20858 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
20859 there is no use of GNAT.Sockets.Constants.
20860 Remove remaining pragma Import for C_Write
20861 Remove C_Read and C_Write from internal implementation unit
20862 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
20863 the read and write functions from the system runtime library is fine
20864 on UNIX but won't work under Windows).
20866 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
20867 (Check_Selector): Use C_Recv instead of C_Read.
20868 Selectors are the GNAT.Sockets abstraction to perform a select()
20869 call on a set of descriptors. To allow abortion of an ongoing
20870 select operation, some data is written to a dedicated socket that
20871 is always monitored.
20872 Under Windows, the write and read library functions cannot operate
20873 on sockets, so we need to use send and recv instead, which is portable
20874 across all supported platforms.
20876 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
20877 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
20878 (using the read and write functions from the system runtime library is
20879 fine on UNIX but won't work under Windows).
20881 2004-10-26 Nicolas Setton <setton@act-europe.fr>

20887 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
20888 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
20891 * Makefile.in: Add support for building shared libraries under Darwin.
20892 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
20893 the low level EH init subprogram to be called from __gnat_initialize.
20895 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
20896 indicates which options to pass to the archive indexer.
20898 * mlib-utl.adb: Add support for calling ranlib with additional
20899 options. This is needed for instance under Mac OS X.
20900 (Ranlib_Options): New global variable, used to store the potential
20901 options to pass to ranlib.
20902 (Ar): Use Ranlib_Options when spawning ranlib.
20903 (Initialize): Set the value of ranlib option.
20905 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
20907 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
20908 instead of 8K, to reflect the real potential needs for stack-checking
20911 2004-10-26 Pascal Obry <obry@gnat.com>
20913 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
20915 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
20916 Windows only the initial thread stack size can be set so it is good to
20917 start we a low stack size.
20918 The OS will adjust the size as needed.
20920 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
20921 Nicolas Setton <setton@act-europe.fr>
20923 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
20924 "__unix__" instead of "unix".
20925 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
20926 sections were just mistakenly ignored. The former is
20927 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
20928 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
20929 of hpux. This prevents an unwanted definition of the symbol
20930 convert_addresses in adaint.o.
20932 2004-10-26 Gary Dismukes <dismukes@gnat.com>
20934 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
20935 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
20937 2004-10-26 Cyrille Comar <comar@act-europe.fr>
20939 * a-filico.ads, a-filico.adb: fix incorrect header.
20941 2004-10-26 Javier Miranda <miranda@gnat.com>
20943 * a-ststio.ads: Fix typo in identifier
20945 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
20947 * sem_ch4.adb: Minor reformatting.
20949 2004-10-26 Ed Schonberg <schonberg@gnat.com>
20951 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
20952 enabled, check the result of unary and binary operations when the
20953 expression is the right-hand side of an assignment.
20955 2004-10-26 Vincent Celier <celier@gnat.com>
20957 * clean.adb (Delete): Do not output warnings when in quiet output and
20958 not in verbose mode.
20959 (Force_Deletions): New Boolean flag, defaulted to False
20960 (Delete): Only delete a file if it is writable, and when
20961 Force_Deletions is True.
20962 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
20963 (Usage): Line for new switch -f
20964 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
20967 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
20969 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
20970 JM type only if its size matches that of the wrapper. When a size is
20971 prescribed and the field is not aliased, remove the wrapper of a JM
20972 type only if the size is not greater than that of the packed array.
20973 (gnat_to_gnu_entity): Change the extension of packed array wrappers
20976 2004-10-26 Geert Bosch <bosch@gnat.com>
20978 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
20979 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
20980 (Pred): Implement in terms of Succ.
20982 2004-10-26 Ed Schonberg <schonberg@gnat.com>
20984 * exp_aggr.adb (Safe_Component): An aggregate component that is an
20985 unchecked conversion is safe for in-place use if the expression of the
20986 conversion is safe.
20987 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
20988 be expandable in place even if the aggregate does not come from source.
20989 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
20990 designated object of an allocator in place, rather than building it
20991 first on the stack. The previous scheme forces a full copy of the array,
20992 and may be altogether unsusable if the size of the array is too large
20993 for stack allocation.
20995 2004-10-26 Robert Dewar <dewar@gnat.com>
20997 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
20998 compares if the component is atomic.
21000 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
21001 array assignment if the component type is atomic.
21003 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21004 Eric Botcazou <ebotcazou@act-europe.fr>
21006 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
21007 is aliased and is a by_reference type, do not pass by copy.
21008 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
21009 detect whether the call is in the right side of an assignment or
21010 the expression of an object declaration. Recurse on component
21011 association within aggregates.
21012 Call it in the condition that determines whether the temporary is
21013 necessary for correct stack-checking.
21015 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
21017 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
21018 RACW_Type, used in the PolyORB version.
21019 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
21020 version and the GARLIC version.
21022 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
21023 Rename RCI_Info to RCI_Locator for better consistency between the
21024 GARLIC and PolyORB versions of the distributed systems annex.
21025 (DSA_Implementation_Name): This enumeration lists the possible
21026 implementations of the Partition Communication Subsystem for the
21027 Distributed Systems Annex (DSA). The three available implementations
21028 are the dummy stub implementation (No_DSA), and two versions based on
21029 two different distribution runtime libraries: GARLIC and PolyORB. Both
21030 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
21032 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
21035 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
21036 between the GARLIC and PolyORB versions of the distributed systems
21038 Remove RE_Unbounded_Reclaim_Pool since it is unused.
21040 2004-10-26 Gary Dismukes <dismukes@gnat.com>
21042 * gnat1drv.adb: Suppress calling the back end when
21043 Frontend_Layout_On_Target is true.
21045 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
21047 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
21048 Set_Read_Only): New subprograms.
21049 These new routines allow the user to set or unset the Owner execute
21050 and Owner write permission flags on a file.
21052 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
21053 GNAT.OS_Lib.Set_Executable instead of rolling our own.
21055 2004-10-26 Matthew Gingell <gingell@gnat.com>
21057 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
21059 2004-10-26 Pascal Obry <obry@gnat.com>
21061 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
21062 memory before the faulting page we properly test the process read
21063 access for this address using appropriate Win32 routine.
21064 (HPUX sections): guard with "__hpux__" instead of "hpux".
21066 2004-10-26 Robert Dewar <dewar@gnat.com>
21068 * lib-xref.adb (Generate_Reference): Don't complain about reference to
21069 entry parameter if pragma Unreferenced set, since we do not properly
21070 handle the case of multiple parameters.
21072 2004-10-26 Vincent Celier <celier@gnat.com>
21074 * prj-env.adb: (Contains_ALI_Files): New Boolean function
21075 (Ada_Objects_Path.Add): For a library project, add to the object path
21076 the library directory only if there is no object directory or if the
21077 library directory contains ALI files.
21078 (Set_Ada_Paths.Add.Recursive_Add): Ditto
21080 2004-10-26 Vincent Celier <celier@gnat.com>
21082 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
21083 extension of library projects.
21085 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
21086 path defaults to ".:<prefix>/lib/gnat".
21087 (Parse): For an extending all project, allow direct import of a project
21088 that is virtually extended.
21090 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
21091 the specified name is directly imported, return its ID. Otherwise, if
21092 an extension of this project is imported, return the ID of the
21095 2004-10-26 Robert Dewar <dewar@gnat.com>
21097 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
21098 (Sub3): New procedure, used by Scaled_Divide
21099 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
21100 correct more than one instance of failure to propagate carries
21102 (Double_Divide): Handle overflow case of largest negative number
21103 divided by minus one.
21105 * s-arit64.ads (Double_Divide): Document that overflow can occur in
21106 the case of a quotient value out of range.
21109 2004-10-26 Robert Dewar <dewar@gnat.com>
21111 * s-bitops.adb (Bit_Eq): Remove redundant check.
21113 * s-bitops.ads: Minor comment updates
21114 Change some occurrences of Address to System.Address
21116 * s-carsi8.ads: Fix minor cut-and-paste error in comments
21118 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21120 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
21121 accessibility check to prefix that is a protected operation.
21123 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21125 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
21126 empty, post message on stub.
21128 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21129 Javier Miranda <miranda@gnat.com>
21131 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
21132 current instance appears within a unit that is directly in the context
21134 Used to determine whether the body of the instance should be analyzed
21135 immediately after its spec, to make its subprogram bodies available
21136 for front-end inlining.
21137 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
21138 constraint is not allowed on the component type (AARM 12.5.3(3))
21140 2004-10-26 Cyrille Comar <comar@act-europe.fr>
21142 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
21143 'Storage_Pool): enhance, document & limit detection of non-sharable
21146 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
21148 * s-pooglo.ads: Add more documentation now that this pool is properly
21151 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21153 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
21154 or protected type with discriminants, do not constrain the
21155 corresponding record type if the subtype declaration has no
21156 discriminant constraints. This can be the case in source code, or in
21157 the subtype declaration created to rename an actual type within an
21160 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21162 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
21163 different kind of stub (possibly wrong name for file), do not check
21165 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
21166 includes call to some function that returns an unconstrained type, do
21169 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21171 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
21172 appear in the code for the main unit. Dependencies among units in the
21173 context of the main unit are established when those other units are
21174 compiled. Otherwise spurious elaboration constraints can generate
21175 incorrect elaboration circularities.
21177 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
21178 Ed Schonberg <schonberg@gnat.com>
21180 * sem_util.adb (Is_Aliased_View): Defend against the case where this
21181 subprogram is called with a parameter that is not an object name. This
21182 situation arises for some cases of illegal code, which is diagnosed
21183 later, and in this case it is wrong to call Is_Aliased, as that might
21184 cause a compiler crash.
21185 (Explain_Limited_Type): Refine previous fix to include
21186 inherited components of derived types, to provide complete information.
21188 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
21189 is the prival for a protected object.
21190 It is necessary to mark this entity as a variable, in addition to
21191 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
21192 modified to avoid checking the Aliased flag on entities that are not
21193 objects. (Checking that flag for non-objects is erroneous and could
21194 lead to a compiler crash).
21196 2004-10-26 Robert Dewar <dewar@gnat.com>
21198 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
21199 X_Frac = 0.5, then we know that the number X must be positive.
21200 (Succ): Remove the same redundant test, and also fix the primary test
21201 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
21203 (Decompose): Add fuller comments to spec
21205 2004-10-26 Pascal Obry <obry@gnat.com>
21207 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
21208 validity (process must have read access). Set to 0 in all other cases.
21209 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
21210 violation on Win32.
21211 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
21212 segmentation violation.
21214 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
21216 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
21217 whose type is a constructed subtype of an aliased object with an
21218 unconstrained nominal subtype, convert the actual to the constructed
21219 subtype before taking its address.
21221 2004-10-26 Vincent Celier <celier@gnat.com>
21223 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
21224 (Is_Path_Name_Case_Sensitive): New function
21226 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
21227 (Base_Name, Simple_Name, Current_Directory, Compose,
21228 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
21231 2004-10-26 Cyrille Comar <comar@act-europe.fr>
21232 Vasiliy Fofanov <fofanov@act-europe.fr>
21233 Vincent Celier <celier@gnat.com>
21235 * gnat_ugn.texi: Generalize "finding memory problems" section into a
21236 "memory management issues" section and document some of the useful
21237 memory pools provided as part of the GNAT library.
21238 Remove "virtual" from declaration of A::method2 in
21239 the simple example of Ada/C++ mixed system.
21240 Library Projects may be virtually extended: their virtual extensions
21241 are not Library Projects.
21242 Added section on extending project hierarchies.
21244 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
21246 * adaint.c (__gnat_get_libraries_from_registry): Cast value
21248 (__gnat_portable_spawn): Remove const.
21250 * mingw32.h (MAXPATHLEN): Check for previous definition.
21252 2004-10-17 Matthias Klose <doko@debian.org>
21254 * gnatvsn.ads: Set gnat library version to 4.0.
21256 2004-10-05 Vincent Celier <celier@gnat.com>
21258 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
21260 2004-10-04 Laurent GUERBY <laurent@guerby.net>
21263 * Makefile.in: Define and use RANLIB_FLAGS.
21265 2004-10-04 Pascal Obry <obry@gnat.com>
21267 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
21268 other x86 platforms).
21270 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
21272 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
21273 in general and triggers stack alignment adjustment for thread entry
21274 points on targets where this is necessary.
21276 2004-10-04 Bernard Banner <banner@gnat.com>
21279 * Makefile.in: Add section for powerpc linux
21280 Add variant i-vxwork-x86.ads
21282 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
21284 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
21286 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
21287 table registration calls when need be. Ensures no reference to the crt
21288 ctors symbol are issued in the SJLJ case, which avoids possible
21289 undefined symbol errors in the case of modules to be statically linked
21292 2004-10-04 Javier Miranda <miranda@gnat.com>
21294 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
21295 in-line the code corresponding to subprogram Analyze_Actuals. In
21296 addition, analyze the actuals only in case of subprogram call.
21298 2004-10-04 Ed Falis <falis@gnat.com>
21300 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
21302 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
21304 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
21305 in the documentation.
21307 2004-10-04 Robert Dewar <dewar@gnat.com>
21309 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
21311 (Analyze_Block_Statement): Add circuitry to detect following dead code
21312 (Check_Unreachable_Code): Handle case of block exit
21314 2004-10-04 Robert Dewar <dewar@gnat.com>
21316 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
21317 (XMatchD): Avoid warning for Logic_Error call
21319 2004-10-04 Robert Dewar <dewar@gnat.com>
21321 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
21322 consider expressions buried within a procedure actual to be an actual.
21323 This caused some blowups with uses of packed slices within a procedure
21326 2004-10-04 Robert Dewar <dewar@gnat.com>
21328 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
21329 longer need to be initialized to zero.
21330 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
21331 initialized to zero.
21333 * checks.adb (Expr_Known_Valid): Packed arrays are now always
21334 considered valid, even if the representation is modular. That's correct
21335 now that we no longer initialize packed modular arrays to zero.
21337 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
21338 suffixes. These are now documented as the only cases in which the
21339 debugger ignores outer records.
21340 Previously, the spec allowed arbitrary suffixes for this purpose.
21341 Change name of LJM to JM for packed array pad records
21342 Create separate section on packed array handling, and add a whole new
21343 set of comments to this section describing the situation with packed
21344 modular types and justification requirements depending on endianness.
21346 2004-10-04 Robert Dewar <dewar@gnat.com>
21348 * a-except.adb: Add a comment for last change
21350 * einfo.ads: Minor spelling correction in comment
21352 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
21354 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
21357 * sem_util.ads: Minor comment update
21359 2004-10-04 Ed Schonberg <schonberg@gnat.com>
21361 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
21362 Inline_Always when in Configurable_Run_Time mode.
21364 * sem_prag.adb (Process_Convention): If entity is an inherited
21365 subprogram, apply convention to parent subprogram if in same scope.
21366 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
21367 when in Configurable_Run_Time mode.
21369 2004-10-04 Ed Schonberg <schonberg@gnat.com>
21371 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
21372 class_wide type after component list has been inherited.
21374 2004-10-04 Ed Schonberg <schonberg@gnat.com>
21376 * sem_ch12.adb (Check_Generic_Actuals): New predicate
21377 Denotes_Previous_Actual, to handle properly the case of a private
21378 actual that is also the component type of a subsequent array actual.
21379 The visibility status of the first actual is not affected when the
21380 second is installed.
21381 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
21382 make fully recursive the treatment of formals of packages declared
21384 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
21385 the above on exit from an instantiation.
21386 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
21387 current instantiation which is now complete.
21388 (Analyze_Package_Instantiation): No instantiated body is needed if the
21389 main unit is generic. Efficient, and avoid anomalies when a instance
21390 appears in a package accessed through rtsfind.
21392 2004-10-04 Ed Schonberg <schonberg@gnat.com>
21394 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
21395 do not generate a declaration for a temporary if the call is part of a
21396 library-level instantiation.
21398 2004-10-04 Ed Schonberg <schonberg@gnat.com>
21400 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
21401 searching for a limited component to flag.
21403 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
21404 expansion of Input, to account for the fact that the implicit call
21405 generated by the attribute reference must freeze the user-defined
21406 stream subprogram. This is only relevant to 'Input, because it can
21407 appear in an object declaration, prior to the body of the subprogram.
21409 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
21410 expansion can proceed and further errors uncovered.
21411 (Minor clean up): Fix cases of using | instead of \ for continuation
21414 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
21416 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
21418 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
21419 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
21420 Use gcc_assert and gcc_unreachable.

21423 specified alignment before validating size.
21424 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
21425 stripped-down declaration for the type of the inner field when making
21428 * utils.c (finish_record_type): Do not compute the size in units
21429 incrementally. Instead compute it once for the rep clause case.
21430 Use gcc_assert and gcc_unreachable.
21432 2004-10-04 Vincent Celier <celier@gnat.com>
21434 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
21436 (Is_Valid_Path_Name): Take '/' as a directory separator.
21438 2004-10-04 Vincent Celier <celier@gnat.com>
21440 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
21441 (Extended_Project) only if Extended_Project is defined, to avoid
21443 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
21445 (Parse_Single_Project): Ditto.
21447 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
21448 Add_To_Project_Path for virtual projects.
21450 2004-10-04 Vincent Celier <celier@gnat.com>
21452 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

21455 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
21456 parameter Options_2.
21458 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
21459 Build_Dynamic_Library with an empty Options_2.
21461 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
21464 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
21465 directory separator, if any.
21466 (Gprmake): Do not allow mains on the command line for library projects.
21467 Do not attempt to link when the project is a library project.
21468 (Library_Opts): New table to store Library_Options.
21469 (Build_Library): If Library_Options is specified, pass these options
21470 when building a shared library.
21472 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
21474 * s-tposen.adb (Service_Entry): The object must be always unlocked at
21475 the end of this procedure now that the unlock operation was inserted
21478 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
21480 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
21481 corresponding to the Preallocated_Stacks flags in System.
21482 (Get_Target_Parameters): Including the processing for
21483 Preallocated_Stacks.

21493 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
21494 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
21495 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
21496 used to signal whether the compiler creates the required stacks and
21497 descriptors for the different tasks (when True) or it is done by the
21498 underlying operating system at run time (when False).
21499 It is initially set to False in all targets.
21501 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
21502 if it is supported by the target.
21503 (Make_Task_Create_Call): Pass the stack address if it has been
21504 previously created. Otherwise pass a Null_Address.
21506 * snames.adb: Add _stack.
21508 * snames.ads: Add Name_uStack. Required to allow the expander to
21509 statically allocated task stacks.
21511 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
21512 Stack_Address argument.
21513 Check that its value is equal to Null_Address because this target does
21514 not support the static stack allocation.
21516 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
21518 * usage.adb: Change "pragma inline" to "pragma Inline" in information
21521 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
21523 * exp_dist.adb: Split declaration of asynchronous flag out of
21524 Add_RACW_Read_Attribute.
21525 Minor reformatting for better alignment with PolyORB version.
21526 Store the entity for the asynchronous flag of an RACW, rather than the
21527 expression, in the asynchronous flags table. This will allow this flag
21528 to be used in other subprograms beside Add_RACW_Read_Attribute.
21530 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
21532 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

21536 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
21537 sockets constant MSG_NOSIGNAL (Linux-specific).
21538 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
21539 all Send operations.
21540 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
21541 from trigerring SIGPIPE.
21542 Rename components to avoid clash with Ada 2005 possible reserved
21544 (Check_Selector): When the select system call returns with an error
21545 condition, propagate Socket_Error to the caller.
21547 2004-10-01 Jan Hubicka <jh@suse.cz>
21549 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

21555 instead do this at freeze time (we won't do it if there is an address
21557 Change "pragma inline" to "pragma Inline" in information and error
21559 Minor reformatting.
21561 * freeze.adb (Check_Address_Clause): Remove previous change, not the
21562 right way of doing things after all.
21563 (Freeze_Entity): For object, set Is_Public for imported entities
21564 unless there is an address clause present.
21566 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
21568 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
21569 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
21570 ensures proper handling of types with rep clauses, which might have
21571 their TYPE_SIZE set already.
21573 2004-09-21 Robert Dewar <dewar@gnat.com>
21575 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
21576 packed array types in both little- and big-endian cases. This change
21577 ensures that we no longer count on the unused bits being initialized
21578 for such types (and in particular ensures that equality testing will
21579 only read the relevant bits).
21580 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
21581 These changes mean that we no longer need to initialize small packed
21583 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
21584 optimization to an LJM field as to its parent field.
21586 * ada-tree.h, trans.c, utils.c, utils2.c:
21587 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
21589 2004-09-20 Jan Hubicka <jh@suse.cz>
21591 * utils.c (gnat_finalize): Remove.
21592 (end_subprog_body): Directly call cgraph_finalize_function;
21593 do not lower the nested functions.
21595 2004-09-20 Robert Dewar <dewar@gnat.com>
21598 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
21599 if an address clause is present, since that means that the Import
21602 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
21604 * 5tsystem.ads: Removed, no longer used.
21606 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
21607 Zack Weinberg <zack@codesourcery.com>
21609 * ada-tree.def: Use tree_code_class enumeration constants
21610 instead of code letters.
21611 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
21612 Update for new tree-class enumeration constants.

21627 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
21628 an existing directory.
21629 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
21630 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
21631 Convert the result to File_Size.
21633 * prj.ads: (Project_Error): New exception
21635 * prj-attr.adb: Except in procedure Initialize, Fail comes from
21636 Prj.Com, not from Osint.
21637 (Attrs, Package_Attributes): Tables moved to private part of spec
21638 (Add_Attribute, Add_Unknown_Package): Moved to new child package
21640 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
21641 Prj.Project_Error after call to Fail.
21642 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
21643 Fail. Check that package name is not already in use.
21645 * prj-attr.ads: Comment updates to indicate that all subprograms may be
21646 used by tools, not only by the project manager, and to indicate that
21647 exception Prj.Prj_Error may be raised in case of problem.
21648 (Add_Unknown_Package, Add_Attribute): Moved to new child package
21650 (Attrs, Package_Attributes): Table instantiations moved from the body to
21651 the private part to be accessible from Prj.Attr.PM body.
21653 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
21654 from new package Prj.Attr.PM.
21655 (Parse_Attribute_Declaration): Call Add_Attribute from new package
21658 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
21660 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
21661 instead of Elaboration_Checks).
21663 * a-calend.adb: Minor reformatting
21665 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

21703 2004-09-09 Jose Ruiz <ruiz@act-europe.fr>
21705 * gnat_ugn.texi: Add Detect_Blocking to the list of configuration
21706 pragmas recognized by GNAT.
21708 * gnat_rm.texi: Document pragma Detect_Blocking.
21710 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
21711 raise Program_Error if called from a protected operation.
21713 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
21714 the protected action nesting level.
21715 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
21716 protected action nesting level.
21717 (Unlock): When pragma Detect_Blocking is active decrease the protected
21718 action nesting level.
21720 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
21721 Protected_Action_Nesting.
21723 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
21724 Common_ATCB record. It contains the dynamic level of protected action
21725 nesting for each task. It is needed for checking whether potentially
21726 blocking operations are called from protected operations.
21727 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
21728 Detect_Blocking is active or not in the partition.
21730 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
21731 raise Program_Error if called from a protected operation.

21740 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
21741 raise Program_Error if called from a protected operation, and increase
21742 the protected action nesting level.
21743 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
21744 Program_Error if called from a protected operation, and increase the
21745 protected action nesting level.

21747 protected action nesting level.
21749 * s-tposen.adb (Lock_Entry): When pragma Detect_Blocking is active,
21750 raise Program_Error if called from a protected operation, and increase
21751 the protected action nesting level.
21752 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
21753 Program_Error if called from a protected operation, and increase the
21754 protected action nesting level.

21759 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
21760 protected action nesting level.
21762 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
21763 insertion of the statement raising Program_Error. The run time
21764 contains the required machinery for handling that.
21766 * sem_util.ads: Change comment associated to procedure
21767 Check_Potentially_Blocking_Operation.
21768 This procedure does not insert a call for raising the exception because
21769 that is currently done by the run time.
21771 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
21773 * init.c: Add the global variable __gl_detect_blocking that indicates
21774 whether pragma Detect_Blocking is active (1) or not (0). Needed for
21775 making the pragma available at run time.
21776 (__gnat_set_globals): Pass and update the detect_blocking parameter.
21778 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
21779 pragma Detect_Blocking is active.
21781 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
21783 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
21784 DB is found in the ali file. Any unit compiled with pragma
21785 Detect_Blocking active forces its effect in the whole partition.
21787 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
21788 Detect_Blocking is active and delay is called from a protected
21791 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
21792 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
21793 Detect_Blocking is active (0 otherwise).
21794 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
21795 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
21798 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
21800 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
21801 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
21804 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
21805 (Register_Receiving_Stub): Add Subp_Info formal parameter.
21806 Update API in placeholder implemetation of s-parint to reflect changes
21807 in distribution runtime library.
21809 * sem_ch3.adb (Expand_Derived_Record): Rename to
21810 Expand_Record_Extension.
21812 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
21813 primitive operations of potentially distributed object types that have
21814 non-controlling anonymous access formals.
21816 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
21818 New implementation of expansion for remote access-to-subprogram types,
21819 based on the RACW infrastructure.
21820 This version of sem_dist is compatible with PolyORB/DSA as well as
21823 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
21824 Asynchrronous that applies to a remote access-to-subprogram type, mark
21825 the underlying RACW type as asynchronous.
21827 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
21828 __gnat_using_gnu_linker to 1.
21830 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
21831 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
21832 GNAT.Perfect_Hash_Generators, and remove the empty
21833 GNAT.Perfect_Hash package.
21835 * atree.adb: Minor reformatting
21837 * exp_ch3.adb (Expand_Derived_Record): Rename to
21838 Expand_Record_Extension.
21839 (Build_Record_Init_Proc.Build_Assignment): The default expression in
21840 a component declaration must remain attached at that point in the
21841 tree so New_Copy_Tree copies it if the enclosing record type is derived.
21842 It is therefore necessary to take a copy of the expression when building
21843 the corresponding assignment statement in the init proc.
21844 As a side effect, in the case of a derived record type, we now see the
21845 original expression, without any rewriting that could have occurred
21846 during expansion of the ancestor type's init proc, and we do not need
21847 to go back to Original_Node.
21849 * exp_ch3.ads (Expand_Derived_Record): Rename to
21850 Expand_Record_Extension.
21852 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
21853 Returns the RACW type used to implement a remote access-to-subprogram
21855 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
21856 New subprograms. Used to create a proxy tagged object for a remote
21857 subprogram. The proxy object is used as the designated object
21858 for RAS values on the same partition (unless All_Calls_Remote applies).
21859 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
21860 System.Partition_Interface.Get_Unique_Remote_Pointer.
21861 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
21862 Renamed from Add_RAS_*_Attribute.
21863 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
21865 New implementation of expansion for remote access-to-subprogram types,
21866 based on the RACW infrastructure.
21868 * exp_dist.ads (Copy_Specification): Update comment to note that this
21869 function can copy the specification from either a subprogram
21870 specification or an access-to-subprogram type definition.
21872 2004-09-09 Ed Schonberg <schonberg@gnat.com>
21874 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
21875 in an instance, between an explicit subprogram an one inherited from a

22130 for a global aliased object with a variable size and an unconstrained
22131 nominal subtype, pretend there is no initializer if the one we have is
22132 incomplete, and avoid referencing an inexistant component in there. The

22157 unit, this is an attempt to inline a construct that is not available in
22158 the current restricted mode, so abort rather than trying to continue.
22160 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
22161 discriminants that rename those of the parent, recover names of
22162 original discriminants for the constraint on the full view of the

22193 returning C.int, to avoid using a derived boolean type.
22195 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

22224 ignore overflows on low and high bounds of an index to also account for
22225 differences in signedness between sizetype and gnu_index_subtype.
22226 These are as legitimate as the ones caused by a lower TYPE_PRECISION

26407 * osint.adb (Executable_Prefix): Set Exec_Name to the current
26408 executable name when not initialized. Otherwise, use its current value.
26410 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
26411 initialize it to another executable name than the current one. This
26412 allows to configure paths for an executable name (gnatmake) different
26413 from the current one (gnatdist).
26415 2004-03-29 Ed Schonberg <schonberg@gnat.com>
26417 * exp_ch6.adb (Expand_Call): A call to a function declared in the
26418 current unit cannot be inlined if it appears in the body of a withed
26419 unit, to avoid order of elaboration problems in gigi.
26421 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
26422 information for protected (wrapper) operation as well, to simplify gdb
26425 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
26426 protected body, indicate that the entity for the generated spec comes
26427 from source, to ensure that references are properly generated for it.

26462 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
26464 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
26465 attribute reference does not denote a subtype, it can be any
26466 expression that has a classwide type, potentially after an implicit
26467 dereference. In particular, the prefix can be a view conversion for
26468 a classwide type (for which Is_Object_Reference holds), but it can
26469 also be a value conversion for an access-to-classwide type. In the
26470 latter case, there is an implicit dereference, and the original node
26471 for the prefix does not verify Is_Object_Reference.
26473 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
26474 conversion of a discriminant-dependent component of a mutable object
26477 2004-03-25 Ed Schonberg <schonberg@gnat.com>
26479 * freeze.adb (Freeze_Entity): When an inherited subprogram is
26480 inherited, has convention C, and has unconstrained array parameters,
26481 place the corresponding warning on the derived type declaration rather
26482 than the original subprogram.

26498 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
26499 value expressions to ensure that calls within a component definition
26500 will be checked (since those are evaluated during the record type's

26552 declaration for a child subprogram body that acts as a spec, indicate
26553 that the entity in the declaration needs debugging information.
26555 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
26556 full view if the subtype is created for a constrained record component;
26557 gigi has enough information to construct the record, and there is no
26558 place in the tree for the declaration.
26560 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
26561 serial number for the dummy body that is built for analysis, to avoid
26562 inconsistencies in the generation of internal names when compiling

26599 Minor reformatting.
26601 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
26603 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
26604 as regular exception objects and not as mere integers representing the
26605 condition code. The latter approach required some dynamics to mask off
26606 severity bits, which did not fit well into the GCC table based model.
26607 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
26608 exception data objects. We don't it and it would conflict with the other
26609 external symbol we have to generate for such exceptions.
26611 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
26612 the special code for VMS exceptions, since these are now represented
26613 as regular exceptions objects.
26615 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
26617 * decl.c (debug_no_type_hash): Remove.

26643 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
26644 Specific.Set instead of direct call to e.g pthread_setspecific.
26646 2004-03-18 Thomas Quinot <quinot@act-europe.fr>

26650 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and

26653 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
26655 * init.c [VxWorks]: Do not fix the stack size for the environment task.
26656 When needed (stack checking) the stack size is retrieved
26657 from the VxWorks kernel.
26659 * Makefile.in: Flag -nostdinc is required when building the run time
26660 for avoiding looking for files in the base compiler.
26661 Add the VxWorks specific version of the package body for
26662 System.Stack_checking.Operations (5zstchop.adb).
26664 * Make-lang.in: Add the object file for
26665 System.Stack_Checking.Operations.

26673 checking from this package to package System.Stack_Checking.Operations.
26674 This way, stack checking operations are only linked in the final
26675 executable when using the -fstack-check flag.

26690 the procedures Add_To_Path_File.
26691 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
26692 making sure that each directory is present only once and, for object
26693 dirs, when a directory already present is added, the duplicate is
26694 removed and the directory is always put as the last in the table.
26695 Write the path files at the end of these accumulations.
26697 * prj-nmsc.adb (Record_Source): Add source file name in hash table
26698 Files_Htable for all sources.

26718 * sem_warn.adb (Check_References): For a warning on a selected
26719 component that does not come from source, locate an uninitialized
26720 component of the record type to produce a more precise error message.
26722 2004-03-15 Jerome Guitton <guitton@act-europe.fr>

26732 pragma used for a private type.
26734 * lib-xref.adb (Generate_Reference): Do not generate warning if
26735 reference is in a different unit from the pragma Unreferenced.
26737 * 5vtpopde.adb: Minor reformatting
26738 Fix casing of To_Task_ID
26740 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
26741 flag if we have an unchecked conversion to an access type in the same
26744 2004-03-15 Geert Bosch <bosch@gnat.com>
26746 * a-ngcoty.adb (Modulus): In alternate formula for large real or
26747 imaginary parts, use Double precision throughout.
26749 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
26750 we want to be able to compile run-time with -gnata for testing, but
26751 this may also be instantiated in user code that is compiled with -gnata.
26753 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
26755 * s-stalib.ads (Exception_Code): New type, to represent Import/Export

26757 throughout the various run-time units.
26758 (Exception_Data): Use Exception_Code for Import_Code.
26760 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of

26763 with the severity bits masked off.
26764 (Register_VMS_Exception): Handle the additional exception data pointer

26770 occurrence matches some handler choice specification. Extracted out of
26771 get_action_description_for, and expanded to take care of the VMS
26773 (get_action_description_for): Use is_handled_by instead of an explicit
26774 complex condition to decide if the current choice at hand catches the
26775 propagated occurrence.

26912 analyze and resolve the rewritten explicit dereference so it is seen
26914 (Insert_Dereference_Action): This procedure is now called only for the

27794 Let finish_record_type decide instead.
27795 Don't make a bitfield if the field is to be addressable.
27796 Always set a size for the field if the record is packed, to ensure the
27797 checks for bitfield creation are triggered.
27798 (finish_record_type): During last pass over the fields, clear
27799 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

27849 error when there are unusual characters (such as '!') in the paths.
27851 * Makefile.generic: When there are sources in Ada and the main is in
27852 C/C++, invoke gnatmake with -B, instead of -z.

27855 from VMS_Conversion.
27856 (Process_Argument): New procedure, extracted from VMS_Conversion. Add

28258 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
28259 N_String_Literal node always references an E_String_Literal_Subtype
28260 entity. This may not be true in the future.
28261 (Possible_Bit_Aligned_Component): Move processing of
28262 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
28264 * exp_ch6.adb (Expand_Thread_Body): Pick up

28269 (Type_May_Have_Bit_Aligned_Components): New function.

28309 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
28310 ineffective elaborate all pragmas on non-visible packages (this
28311 happened when a renamed subprogram was called). Now the elaborate all
28312 always goes on the package containing the renaming rather than the one
28313 containing the renamed subprogram.
28315 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
28316 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

28341 * make.adb (Gnatmake): Special process for files to compile/check when
28342 -B is specified. Fail when there are only foreign mains in attribute

28375 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
28377 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
28378 all attributes, including read-only attribute.
28380 2004-01-05 Pascal Obry <obry@gnat.com>

28389 based on the new naming scheme.
28391 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
28392 scheme for the shared runtime libraries.
28395 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
28397 (install-gnatlib): Do not create symlinks for shared libraries.
28398 (gnatlib-shared-default): Idem.
28399 (gnatlib-shared-dual-win32): New target. Not used for now as the

28401 (gnatlib-shared-win32): Do not create copy for the shared libraries.
28402 (gnatlib-shared-vms): Fix shared runtime libraries names.

28420 pure, emit warning.
28421 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and

28533 to __gnat_map_signal, imported from init.c to support
28534 signal -> exception mappings that depend on the vxWorks version.
28537 Created and exported __gnat_map_signal to support signal -> exception
28538 mapping that is dependent on the VxWorks version.

28567 Minor reformatting throughout
28569 2003-12-11 Ed Schonberg <schonberg@gnat.com>
28571 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
28572 bounds of a loop, create a separate block in order to generate proper
28573 cleanup actions to prevent memory leaks.
28575 * sem_res.adb (Resolve_Call): After a call to
28576 Establish_Transient_Scope, the call may be rewritten and relocated, in
28577 which case no further processing is needed.

28592 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
28595 2003-12-08 Robert Dewar <dewar@gnat.com>
28597 * 7sintman.adb: Minor reformatting
28599 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
28600 standard linker options to get standard libraries linked. We now plan
28601 to provide dummy versions of these libraries to match the appropriate
28602 configurable run-time (e.g. if a library is not needed at all, provide
28603 a dummy empty library).
28605 * targparm.ads: Configurable_Run_Time mode no longer affects linker
28606 options (-L parameters and standard libraries). What we plan to do is
28607 to provide dummy libraries where the libraries are not required.
28609 * gnatbind.adb: Minor comment improvement
28611 2003-12-08 Javier Miranda <miranda@gnat.com>
28613 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
28614 aggregate in the parent. Otherwise constants with limited aggregates

28616 It is required to call the corresponding IP subprogram in case of
28617 default initialized components.
28618 (Gen_Assign): In case of default-initialized component, generate a
28619 call to the IP subprogram associated with the component.
28620 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
28621 of aggregate with default initialized components.
28622 (Has_Default_Init_Comps): Improve implementation to recursively check
28623 all the present expressions.
28625 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
28626 to indicate that the initialization call corresponds to a
28627 default-initialized component of an aggregate.
28628 In case of default initialized aggregate with tasks this parameter is
28629 used to generate a null string (this is just a workaround that must be
28630 improved later). In case of discriminants, this parameter is used to
28631 generate a selected component node that gives access to the discriminant
28634 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
28635 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
28636 allocated aggregates with default-initialized components.
28638 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
28639 the box notation is used in positional aggregates.

28658 Store_Comments is True.
28659 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
28660 comments are associated with these nodes. Store the node IDs in the
28662 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the

28681 Process nodes N_Comment.
28683 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
28684 without comments and there are some comments, set the flag
28685 Unkept_Comments to True.
28686 (Scan): If there are comments, set the flag Unkept_Comments to True and
28687 clear the comments.
28688 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
28689 (Next_End_Nodes: New table
28690 (Comment_Zones_Of): New function

28717 Comment_Id and set Token to Tok_Comment when scanning a comment.
28718 (Set_Comment_As_Token): New procedure
28720 * sinput-p.adb: Update Copyright notice
28721 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
28722 that no longer exists.
28724 2003-12-08 Javier Miranda <miranda@gnat.com>
28726 * sem_aggr.adb: Add dependence on Exp_Tss package
28727 Correct typo in comment
28728 (Resolve_Aggregate): In case of array aggregates set the estimated
28729 type of the aggregate before calling resolve. This is needed to know
28730 the name of the corresponding IP in case of limited array aggregates.
28731 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
28732 in case of default initialized array components.
28734 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

28743 until bounds are analyzed, to diagnose premature use of type.
28745 * sem_util.adb (Wrong_Type): Improve error message when the type of
28746 the expression is used prematurely.

28754 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
28755 they are automatically generated by Make-lang.in and cause nothing but
28756 maintenance troubles.
28758 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
28760 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

28774 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
28775 to ensure that the kernel fills in the interrupted context structure
28776 before calling a signal handler, which is necessary to be able to
28777 unwind past it. Update the copyright notice.
28779 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
28781 * a-elchha.ads: New file.
28783 * a-elchha.adb: New default last chance handler. Contents taken from
28784 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.
28786 * a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine
28787 is moved to a-elchha.adb to provide a target-independent default last

28802 2003-12-05 Samuel Tardieu <tardieu@act-europe.fr>
28804 * g-table.adb: Use the right variable in Set_Item.

28850 (Possible_Bit_Aligned_Component): Maybe_Bit_Aligned_Large_Component new
28851 name. Modified to consider small non-bit-packed arrays as troublesome

28861 2003-12-03 Jose Ruiz <ruiz@act-europe.fr>
28864 When defining LIBGNAT_TARGET_PAIRS for bare board targets, remove the
28865 redundant inclusion of EXTRA_HIE_NONE_TARGET_PAIRS, which is always
28866 included in HIE_NONE_TARGET_PAIRS.
28868 2003-12-03 Ed Schonberg <schonberg@gnat.com>
28871 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
28872 is legal in an instance, because legality is cheched in the template.
28875 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
28876 appplied to an unchecked conversion of a formal parameter.
28879 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

28893 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
28894 so that the debugger can reliably access the value of the parameter,
28895 and therefore is able to display the exception name when an exception
28896 breakpoint is reached.
28898 2003-12-01 Thomas Quinot <quinot@act-europe.fr>
28900 * fmap.adb: Fix typo in warning message.

30235 Remove the test against being in No_Run_Time_Mode before generating a
30236 call to Register_Tag. It is redundant with the test against the
30237 availability of the function Register_Tag.

32443 (title page): Remove date.
32444 (general) Add @./@: where approriate, and two spaces after the
32445 full stop at the end of a sentence. Use @samp markup when
32446 referring concrete lexical entities (keywords, attribute names
32447 etc.), and @syntax for ARM grammar elements. Use @r for English

32507 inspired from the C++ library.

32524 Add 2001 to copyright date
32526 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
32527 need to force universal inlining for these cases.
32529 2001-12-19 Arnaud Charlet <charlet@gnat.com>
32531 * s-taprob.adb: Minor clean ups so that this unit can be used in
32534 * exp_ch7.adb: Allow use of secondary stack in HI mode.

32557 discriminant check if the selected component is a component of
32558 the argument of an initialization procedure.
32560 * trans.c (tree_transform, case of arithmetic operators): If result
32561 type is private, the gnu_type is the base type of the full view,
32562 given that the full view itself may be a subtype.
32564 2001-12-17 Robert Dewar <dewar@gnat.com>
32566 * sem_res.adb: Minor reformatting

32832 2001-12-17 Laurent Pautet <pautet@gnat.com>
32835 Fix comment of Shutdown_Socket and Close_Socket. These functions
32836 should not fail silently because if they are called twice, this
32837 probably means that there is a race condition in the user program.
32838 Anyway, this behaviour is consistent with the rest of this unit.
32839 When an error occurs, an exception is raised with the error message
32840 as exception message.

34174 instead of the previous simple checksum algorithm.
34175 (Time_Stamp_Mismatch): use CRC_Match for comparison.
34176 (Set_Source_Table): idem.
34179 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
34180 instead of simple checksum.
34181 (CRC_Match): new function.
34182 (CRC_Error): new constant.
34184 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
34185 a CRC now and not a simple checksum. A CRC uses lower-case hex
34186 letters, fixes ambiguity in parsing.
34188 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
34189 is what this variable will store.
34191 * bcheck.adb: Change reference to chechsum in comments by CRC.
34192 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
34193 rename All_Checksum_Match to All_CRC_Match. Change due to API
34194 renaming since now GNAT does not use a simple checksum but a
34195 CRC using GNAT.CRC32.
34197 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
34198 now and not anymore a simple checksum.
34200 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
34203 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
34206 (Restore_Scan_State): rename Checksum to CRC.

34211 (Checksum): rename to CRC.
34212 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
34214 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
34215 GNAT.CRC32). Update copyright notice.
34217 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
34218 GNAT.CRC32). Update copyright notice.
34221 (Accumulate_Checksum): removed.
34222 (Update): new procedure. Add a wide-character into the CRC.
34225 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
34226 (Load_File): fix initialization of S (change Source_Checksum to
34229 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
34230 Source_CRC in S initialization.
34232 * sinput.adb (Source_Checksum): renamed to Source_CRC.
34234 * sinput.ads (Source_Checksum): renamed to Source_CRC.
34235 Update comments for the CRC.
34237 * types.adb (Hex): Use lowercase for the letter part.
34239 * types.ads (Get_Hex_String): Returns the hexadecimal representation
34240 for a word. This is currently used only for CRC. In previous version,
34241 the checksum was using a representation with all letter being
34242 upper-case. With the new implementation (using CRC) we do not remove
34243 the 32th bit of the CRC, so we can have an upper-case starting letter
34244 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
34245 It is ambigous since the CRC was optional and could be followed by
34246 options like EB, EE. So now this routines uses lower-case letter for
34247 the hexadecimal representation. Strange enough only lower case letters
34248 where checked in Scan_ALI (even if this was not a possible case).
34250 * gnatvsn.ads (Library_Version): changed to 3.15a.
34252 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
34255 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
34258 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
34259 Add 2001 to copyright notice
34260 (Accumulate_Checksum): Modify to use System.CRC32.
34262 * ali-util.ads: Redo changes of previous revision to continue to use
34263 the word Checksum. Add 2001 to copyright notice.
34265 * ali.adb: Undo some of previous changes, not needed.
34266 Keep the change for lower case letters in the checksum.
34268 * ali.ads: Undo previous change not needed.
34270 * bcheck.adb: Undo most of previous change, not needed.
34271 But do use Checksums_Match for checksum comparison.
34273 * gnatls.adb: Undo most of previous change, not needed.
34274 But do use Checksums_Match for comparing checksums.
34276 * lib-load.adb: Undo previous change, not needed.
34278 * lib-writ.adb: Undo previous change, not needed.
34280 * lib-writ.ads: Document that checksums use lower case,
34281 not upper case letters.

34285 * scans.ads: Undo previous change, not needed.
34287 * scn-nlit.adb: Undo previous changes, not needed.
34289 * scn-slit.adb: Undo previous change, not needed. Fix header format.
34292 (Accumulate_Checksum): Use System.CRC32.
34293 (Initialize_Checksum): New procedure.
34294 Remove other changes of previous revision.
34296 * sinput-p.adb: Undo previous change, not needed.
34298 * sinput.adb: Undo previous change, not needed.
34300 * sinput-l.adb: Undo previous change, not needed.
34302 * sinput.ads: Undo previous change, not needed. Keep only comment
34303 on new checksum algorithm
34305 * Makefile.in: Add s-crc32 as needed, remove g-crc32.
34306 Also remove a-tags and a-stream from GNAT sources.
34308 * ali.adb (Scan_ALI): fix typo introduce in latest check-in.
34310 * Makefile.in (GNATRTL_NONTASKING_OBJS): Add g-crc32.o.
