1200 routines has been replaced by an instantiation of
1201 System.Shared_Storage.Shared_Var_Procs generic package, while expanding
1202 shared variable declaration.
1203 Calls to access and assign routines have been replaced by calls to
1204 Read/Write routines of System.Shared_Storage.Shared_Var_Procs
1205 instantiated package.

1216 For this runtime unit (always compiled in GNAT mode), we allow
1217 stream attributes references for limited types for the case where
1218 shared passive objects are implemented using stream attributes,
1219 which is the default in GNAT's persistent storage implementation.

1224 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
1225 convention from its base type, do not set the type to that of integer,
1226 because it may inherit a size clause.
1227 Warn on a size clause with a size different
1228 from that of Integer, if the type has convention C.

1268 (P_Access_Definition): Change the error message when parsing "access
1269 all" in Ada 95 mode. The message no longer forces the user to recompile

1292 New local subprogram Is_Valid_Remote_Object_Type, replaces
1293 Is_Recursively_Limited_Private.
1294 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
1295 non-controlling formals (and the return type, even though this is not
1296 explicit in the standard) must support external streaming.

1298 as above for of RAS types and RCI subprograms. (The return type is not

1303 * sem_util.ads, sem_util.adb
1304 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
1305 Is_Remote_Call_Interface to identify RACW types in a stable and
1306 consistent way. We used to rely in this predicate on the privateness of
1307 the designated type and its ancestors, but depending on the currently
1308 visible private parts, this caused false negatives. We now uniformly
1309 rely on checks made at the point where the RACW type is declared.

1323 Add missing escaping of all-caps word 'CPP' in error messages.
1324 (Build_Discriminated_Subtype): Do not inherit representation clauses
1325 from parent type if subtype already carries them, because they are
1326 inherited earlier during derivation and already include those that may
1327 come from a partial view.
1329 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
1330 Check the declarations of a subprogram body for proper deferred

1365 operation of an RACW stub type (these primitives are only executed
1366 through dispatching, never through static calls).
1367 (Collect_Interps): When only one interpretation has been found, set N's
1368 Entity and Etype to that interpretation, otherwise Entity and Etype may
1369 still refer to an interpretation that was ignored by Add_One_Interp,
1370 in which case would end up with being marked as not overloaded but with
1371 an Entity attribute not pointing to its (unique) correct interpretation.
1373 2008-05-20 Ed Schonberg <schonberg@adacore.com>
1376 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

1388 location is independent of the point of creation of the itype itself.

5630 subprogram body that acts as its own spec may not have a non-private
5631 WITH clause on a private sibling.
5632 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
5633 child unit is a renaming, create an implicit with_clause on that

5736 perform subtype conformance between the formals of the current entry
5737 and those of the target interface primitive.
5738 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
5739 Timed_Entry_Call): Analyze the triggering statement as the first step of
5740 the processing. If this is a dispatching select, postpone the analysis
5741 of all select statements until the Expander transforms the select. This
5742 approach avoids generating duplicate identifiers after the Expander has
5743 replicated some of the select statements. In case the Expander is
5744 disabled, perform regular analysis.
5745 (Check_Triggering_Statement): New routine.
5746 (Analyze_Requeue): Exclude any interpretations that are not entries when
5747 checking overloaded names in a requeue. Also test type conformance for

6343 multiple inherited interfaces info. This information cannot be stored
6344 in Xref_Entity_Record, which only supports a single instance of Tref_*,

6361 additional management on these nodes in Expand_Interface_Actuals.
6363 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
6364 that handles use of 'Access and 'Unchecked_Access applied to

6410 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
6411 used by VxWorks targets to have access to task-specific data and be
6412 able to extract the stack boundaries for stack checking.

6456 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
6457 association for an access component, add an association with null as
6458 the expression. Remove testing for array subtypes and the setting in
6459 that case of Ctyp to the array component type, which prevented proper
6460 inclusion of an association for null-initialized arrays. Collapse
6461 condition that tests for array subtypes into just a test of
6462 Is_Partially_Initialized_Type (which already covers arrays anyway).

6479 * sem_ch4.adb: Minor code and comment reformatting.
6480 (Analyze_Allocator): When the designated type of an unconstrained

6647 * a-calend-vms.adb, a-calend.adb:
6648 Add a section on leap seconds control along with two entities used to
6649 enable and disable leap seconds support. The array Leap_Second_Times is
6650 now constant and contains hard time values pre-generated. Remove
6651 all elaboration code used to populate the table of leap seconds.
6654 Add entity Leap_Seconds_Support to the list of global run-time variables
6655 along with a comment on its usage and values.
6656 (Gen_Adainit_Ada): Add code to generate the declaration and import of
6657 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
6658 or one (enabled) depending on the presence of binder switch "-y".
6659 (Gen_Adainit_C): Add code to generate the declaration of external int
6660 __gl_leap_seconds_support. Set is value to zero (disabled) or one
6661 (enabled) depending on the presence of binder switch "-y".

6670 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
6671 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
6673 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
6675 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
6676 function which can be called by the debugger to interrupt the tasks of
6677 an Ada application asynchronously, as needed on VxWorks.
6678 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
6680 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
6681 renamed from Stop_All_Tasks. Update comments.
6682 (Stop_All_tasks): New function declaration.
6684 2007-09-26 Olivier Hainque <hainque@adacore.com>
6686 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
6687 #include <utime.h> and #define GCC_RESOURCE_H before
6688 #include <sys/wait.h>.
6689 Add more protections in __gnat_translate_vms.
6691 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
6692 #include <sys/wait.h>.
6694 2007-09-26 Thomas Quinot <quinot@adacore.com>
6695 Sergey Rybin <rybin@adacore.com>
6697 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
6699 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
6702 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
6704 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
6707 * sem_dist.ads: Minor comment fix
6709 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
6711 2007-09-26 Javier Miranda <miranda@adacore.com>
6712 Eric Botcazou <ebotcazou@adacore.com>
6715 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
6716 indirection added to the HT_Link component of the TSD. This is required
6717 to statically allocate the TSD.
6720 Minor reordering of the declarations in the private part. Required to
6721 add a level of indirection to the contents of the TSD component HT_Link.
6722 This is required to statically allocate the TSD.
6724 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
6725 Is_Statically_Allocated set from constant objects.
6726 Do not make exported constants created by the compiler volatile.
6727 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
6730 * trans.c (Identifier_to_gnu): For constants, unshare initializers
6731 before returning them.
6733 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
6734 public part of the package.
6735 (Make_DT): Move HT_Link component out of the TSD record. For this
6736 purpose Make_DT now declares a separate object that stores the
6737 HT_Link value, and initializes the TSD component with the address
6738 of this new object. The addition of this level of indirection is
6739 required to statically allocate the TSD because the TSD cannot
6740 have variable components.
6741 (Expand_Interface_Conversion): Improve the expanded code.
6742 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
6744 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
6745 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
6746 if we are building static dispatch tables then we must not generate
6747 extra code to register the primitive because the dispatch table will
6748 be built at the end of the library package; otherwise we notify that
6749 we cannot build the static dispatch table.
6751 2007-09-26 Robert Dewar <dewar@adacore.com>
6753 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
6756 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
6757 (Analyze_Record_Representation_Clause): Suppress junk warning for
6758 missing component clause.

6760 tests for controlled type overlay to composites with controlled
6762 (Analyze_Record_Representation_Clause): Add reference for component name
6764 2007-09-26 Javier Miranda <miranda@adacore.com>
6765 Gary Dismukes <dismukes@adacore.com>

6768 for thunks associated with interface types.
6770 * einfo.ads: Improve documentatation of Is_Internal
6771 (Is_Thunk): New attribute applicable to subprograms. True for thunks
6772 associated with interface types.
6773 Extensive comment fixes regarding flags that appear in all entities. The
6774 documentation is now consistent for all such flags (there were a number
6775 of errors in the documentation in this regard).
6777 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
6779 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
6780 of these procedures are passed a function call that already has
6781 build-in-place actuals (testing new flag
6782 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
6783 the case where processing continues.
6784 (Expand_Call): If the call is generated from a thunk body then we
6785 propagate the extra actuals associated with the accessibility
6786 level of the access type actuals.
6788 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
6789 of each extra formal of a protected operation to reference the
6790 corresponding extra formal of the subprogram denoted by the
6791 operation's Protected_Body_Subprogram.
6793 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
6794 N_Function_Call nodes.
6796 2007-09-26 Robert Dewar <dewar@adacore.com>
6798 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
6800 * debug.adb: Add d.s flag.
6802 2007-09-26 Gary Dismukes <dismukes@adacore.com>
6804 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
6805 debug variable so that it won't be initialized when pragma
6806 Initialize_Scalars is in effect.
6808 2007-09-26 Gary Dismukes <dismukes@adacore.com>
6810 * freeze.adb (Freeze_Entity): Remove check for preelaborable
6811 initialization of a full view. This is moved to
6812 Analyze_Package_Specification.
6814 * sem_ch7.adb (Analyze_Package_Specification): Add check for
6815 preelaborable initialization of a full view in entity loop.
6816 (Uninstall_Declarations): If entity is a use-visible compilation unit,
6817 its child units are use-visible only if they are visible child units.
6819 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
6820 whether an expression can be used within a type declaration that
6821 requires preelaborable init.
6822 (Check_Components): Replace inline code that does partial checking for
6823 preelaborable default expressions with call to
6824 Is_Preelaborable_Expression.
6825 (Has_Preelaborable_Initialization): In the case of a generic actual
6826 subtype, (that is, Is_Generic_Actual is True), return the result of
6827 applying Has_Preelaborable_Initialization to the generic actual's base
6830 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
6832 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
6833 call to Jan_1_Day _Of_Week to optimize its performance.
6834 (Is_Leap): Move the routine to the scope of Week_In_Year.
6835 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
6836 weekday on which January 1 falls of Year - 1 and Year + 1. This function
6837 avoids calling Time_Of and Split, thus making it more efficent.
6838 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
6840 * g-calend.ads (Week_In_Year): Change comment to reflect new
6843 2007-09-26 Emmanuel Briot <briot@adacore.com>
6845 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
6846 Command_Line): New types
6847 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
6848 support for defining how switches can be grouped on a command line (as
6849 is the case for -gnatw... for GNAT), and how simple switches can be
6850 used as aliases for more complex switches (-gnatwa is same as
6852 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
6853 (Start, Current_*): New subprograms
6854 Added support for parsing an array of strings in addition to the real
6856 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
6857 be moved from the body to the private part of the spec.
6858 (*): All subprograms now have an extra parameter with default value to
6859 specify which parser should be used. For backward compatibility, it
6860 defaults to parsing the command line of the application. They were also
6861 modified to properly handle cases where each of the argument does not
6862 start at index 1 (which is always true for Ada.Command_Line, but not
6863 when processing any Argument_List).
6864 (Free): New subprogram
6865 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
6866 Argument): New subprograms
6867 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
6868 special characters like ':', '=',... are now handled in a single place,
6869 which makes the code more extensible eventually.
6870 (Getopt, Full_Switch): When the switch was returned as part of the
6871 special character '*', make sure it is prepended by the switch character
6872 ('-' in general), so that the application knows whether "foo" or "-foo"
6873 was specified on the command line.
6875 2007-09-26 Florian Villoing <villoing@adacore.com>
6877 * g-dirope.adb (Remove_Dir): In case we are removing directories
6878 recursively, make sure that if an exception is raised during the
6879 processing, the current working directory is reset to its initial
6880 value before propagating the exception.
6882 2007-09-26 Vincent Celier <celier@adacore.com>
6884 * gnatbind.adb: If there are several ALI files specified and there is
6885 a main program to bind, the first ALI is expected to contain the main
6886 subprogram and the names of the binder generated files will be derived
6887 from the first ALI file name.
6888 (Gnatbind): Fix insertion character in invocation of Error_Msg
6890 2007-09-26 Vincent Celier <celier@adacore.com>
6892 * gnatcmd.adb (Check_Files): Do not include sources that have been
6893 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
6895 2007-09-26 Ed Schonberg <schonberg@adacore.com>
6897 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
6898 information about each of its index types, following the type
6899 reference for its component type.
6901 2007-09-26 Vincent Celier <celier@adacore.com>
6903 * make.adb: (Kill): New procedure (__gnat_kill imported)

6905 were previously local to procedure Compile_Sources.
6906 (Sigint_Intercepted): Send signal SIGINT to all outstanding
6907 compilation processes.

6910 sources, so that the correct paths will be found.
6912 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
6914 2007-09-26 Vincent Celier <celier@adacore.com>
6916 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
6918 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
6919 Replace components Compiler_Min_Options and Binder_Min_Options with
6920 Compiler_Required_Switches and Binder_Required_Switches in record
6922 Remove components Default_Language and Config in Project_Tree_Data,
6925 * prj-attr.adb: New attributes Required_Switches (<language>) in
6926 packages Compiler and Binder.
6928 * prj-nmsc.adb: Major rewrite of the processing of configuration
6929 attributes for gprbuild. No impact on GNAT tools.
6931 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
6932 process configuration attributes: this is done in Prj.Nmsc.Check.
6933 (Recursive_Process): Make a full copy of packages inherited from project
6934 being extended, instead of a shallow copy.
6935 (Process_Project_Tree_Phase_1): New procedure
6936 (Process_Project_Tree_Phase_1): New procedure
6937 (Process): Implementation now uses the two new procedures
6939 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
6940 from the project config, not the tree config that no longer exists.
6942 2007-09-26 Vincent Celier <celier@adacore.com>

6963 2007-09-26 Ed Schonberg <schonberg@adacore.com>
6965 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
6966 ancestor of the derived type, the operations are inherited from the
6967 primary dispatch table of the parent.
6968 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
6969 when the context is an explicit type conversion.
6971 2007-09-26 Ed Schonberg <schonberg@adacore.com>

7016 no sources, but is an extending project.
7018 2007-09-25 Eric Botcazou <ebotcazou@adacore.com>
7020 * trans.c: Fix misplaced #define.

7125 * s-crtl-vms64.ads: Removed.
7127 2007-09-12 Olivier Hainque <hainque@adacore.com>
7129 * decl.c (gnat_to_gnu_entity) <E_Record_Subtype>: For a subtype
7130 with discriminant constraints, generalize the code for BIT_FIELDs
7131 to PACKED fields of constant size and propagate DECL_PACKED.
7133 2007-09-11 Eric Botcazou <ebotcazou@adacore.com>
7135 * decl.c (array_type_has_nonaliased_component): New predicate.
7136 (gnat_to_gnu_field) <E_Array_Type>: Invoke the above predicate to

7147 in library level record type entities if we are generating statically
7148 allocated dispatch tables.
7150 * exp_disp.adb (Make_Tags/Make_DT): Replace previous code
7151 importing/exporting the _tag declaration by new code
7152 importing/exporting the dispatch table wrapper. This change allows us

7160 allocate the dispatch tables.
7161 (Check_Allocator): Make function iterative instead of recursive.
7162 Also return inner allocator node, when present, so that we do not have
7163 to look for that node again in the caller.

7268 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
7269 create an abstract subprogram in the case of 'Input. For 'Output we now
7270 create a real spec/body when the type is abstract, since it can
7271 potentially be called.
7272 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
7273 body for 'Output when the type is abstract (only the creation of the
7274 body for 'Input is excluded when the type is abstract).
7275 (Stream_Operation_OK): Add an additional condition in the return
7276 statement, so that False will be returned for TTS_Stream_Input if the
7277 associated tagged type is an abstract extension. Add comments for
7279 (Expand_N_Object_Declaration): For the case of a shared passive
7280 variable, insert init proc call only after the shared variable
7281 procedures have been processed, because the IP call needs to undergo
7282 shared passive variable reference expansion, which requires these
7283 procedures to be available (and elaborated).

7294 and the value of the discriminant is the discriminant of the enclosing
7295 type, retrieve its value from the aggregate itself, where it must have
7298 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
7299 to remove other spurious ambiguities on arithmetic operations involving
7300 literals and addresses, on systems where Address is a visible integer
7301 type, when the operator is called in functional notation.
7302 (Try_Primitive_Operation): Within an instance, a call in prefixed form
7303 is legal when the types match, even if the operation is currently
7306 2007-09-10 Ed Schonberg <schonberg@adacore.com>
7308 * sem_ch12.adb (Build_Local_Package): A formal package with no
7309 associations is legal if all formals have defaults. It is not
7310 equivalent to a formal declared with a box.

7340 2007-09-08 Eric Botcazou <ebotcazou@adacore.com>
7342 * decl.c (gnat_to_gnu_entity) <Object>: Simplify the condition under
7343 which a constant renaming is treated as a normal object declaration.
7344 * trans.c (lvalue_required_p) <N_Slice>: New case, extracted from
7345 the N_Indexed_Component case.
7346 <N_Indexed_Component>: Fall through to above case.

7428 (Write_Entity_Flags): Write the status of flag Is_Raised.
7429 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
7430 spurious ambiguities when integer literals appear in the context of an
7431 address type that is a visible integer type.
7433 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
7434 exceptions never being raised.
7435 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

7449 2007-08-31 Gary Dismukes <dismukes@adacore.com>
7451 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
7452 library-level package renaming, pass the declaration associated with
7453 the renaming's special debug variable to Qualify_Entity_Names to ensure
7454 that its encoded name is properly qualified.
7456 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
7457 occurring in the list of entities to qualify, and do not attempt to

7467 access type points to an unconstrained array.
7469 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
7471 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
7474 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect

7485 avoid very deep recursion in the front end, which was causing stack
7488 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
7489 string, and the right operand is a string literal (the case of "" &
7490 "..."), optimize by avoiding copying the right operand -- just use the
7491 value of the right operand directly.
7493 * stringt.adb (Store_String_Chars): Optimize by growing the
7494 String_Chars table all at once, rather than appending characters one by
7496 (Write_String_Table_Entry): If the string to be printed is very long,
7497 just print the first few characters, followed by the length. Otherwise,
7498 doing "pn(n)" in the debugger can take an extremely long time.
7500 * sem_prag.adb (Process_Interface_Name): Replace loop doing
7501 Store_String_Char with Store_String_Chars.

7518 2007-08-31 Ed Schonberg <schonberg@adacore.com>
7520 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
7521 flag, for effiency. It is called when analyzing arithmetic operators
7522 and also for actuals in calls that are universal_integers. The flag is
7523 set for the predefined type address, and for any type or subtype
7526 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
7527 Universal_Integer, when the formal is a descendent of address and the
7528 call appears in user code.
7529 (Analyze_Selected_Component): if the prefix is a private extension, the
7530 tag component is visible.
7532 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an
7535 2007-08-31 Robert Dewar <dewar@adacore.com>
7537 * s-fileio.adb (Open): Normalize file name to lower case in non-case
7538 sensitive file name systems to avoid unexpected mismatch in Vista.

7589 2007-08-16 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
7591 * misc.c (gnat_type_max_size): Constify.
7593 2007-08-16 Gary Dismukes <dismukes@adacore.com>
7595 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
7596 associated with Standard_Debug_Renaming_Type, to be used as the type of
7597 the special variables whose names provide debugger encodings for
7598 renaming declarations.
7600 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
7601 (Set_Debug_Renaming_Link): Change to set Node25.
7602 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
7603 (Write_Field25_Name): Add case for E_Variable to output
7604 "Debug_Renaming_Link".
7605 (Write_Field23_Name): Correct the output string for "Limited_View".
7607 * exp_dbug.adb: Add with and use of Tbuild.
7608 (Debug_Renaming_Declaration): Replace creation of an enumeration type
7609 and literal with creation of a variable of type
7610 Standard_Debug_Renaming_Type whose name encodes both the renamed object
7611 and the entity of the renaming declaration.
7612 (Qualify_Entity_Name): Add the delayed qualification of the entity name
7613 part of the name of a variable that has a Debug_Renaming_Link.
7615 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
7616 special type to be associated with variables that provide debugger

7620 Ed Schonberg <schonberg@adacore.com>
7621 Javier Miranda <miranda@adacore.com>
7623 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
7624 ancestor part given by an aggregate to test for an unchecked conversion,
7625 since this can occur in some cases when the ancestor part is a function
7626 call, and we don't want to fall into the recursive call to this
7627 procedure in that case.
7629 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
7630 stream attributes on limited types to account for user-specified
7631 attributes as well as whether Input (resp. Output) becomes available
7632 due to Read (resp. Write) being available for the type. Change Boolean
7633 variable to the more accurate name
7634 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
7635 double-"not" predicate at beginning of return statement to more
7636 understandable form.
7638 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
7639 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
7640 in a block statement and use that as the first statement of the
7641 expanded return rather than incorrectly using the handled sequence as
7642 the first statement.
7644 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
7645 operation, generate an explicit freeze node for it rather than
7646 generating extra formals, to ensure that gigi has the proper order of
7647 elaboration for anonymous subtypes in the signature of the subprograms.
7648 (Build_In_Place_Formal): Move assertion to beginning of loop.
7649 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
7650 applied to a function call (occurs for some cases of 'Input).
7651 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
7652 applied to a function call (occurs for some cases of 'Input).
7654 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
7655 2005, generate an extended return statement enclosing the result object
7658 * freeze.adb (Freeze_Record_Type): Extend the current management of
7659 components that are access type with an allocator as default value: add
7660 missing support to the use of qualified expressions of the
7661 allocator (which also cause freezing of the designated type!)
7662 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
7663 dispatching operation, since extra formals may be needed by calls to
7664 build-in-place functions (such as stream 'Input).
7666 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
7667 formals for 'Constrained and accessibility level in the case of a
7668 predefined dispatching operation.
7670 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
7671 point, no need to find the parent node.
7673 2007-08-16 Javier Miranda <miranda@adacore.com>
7675 * exp_attr.adb (Attribute_Priority): Add missing support for entries
7678 2007-08-16 Javier Miranda <miranda@adacore.com>
7680 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
7681 is not really required and can introduce regression with the debugger.
7682 The original problem is fixed with the patch written for checks.adb.
7684 2007-08-16 Thomas Quinot <quinot@adacore.com>
7686 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

7691 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
7692 Including_Non_Switch set to False.
7693 (Gnatmake): For the compiler, call Test_If_Relative_Path with
7694 Including_Non_Switch set to False.
7696 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
7697 parameter Including_Non_Switch, defaulted to True. When
7698 Including_Non_Switch is False, options that are not switches and
7699 appear as relative path are not converted to absolute paths.

7711 currently inspected is a selected component, retrieve the entity of
7713 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
7714 from the immediate ancestor of Main_Unit_Entity.
7715 (Install_Limited_Withed_Unit): Do not install the limited view of
7716 package P if P is reachable through an ancestor chain from package C
7717 and C also has a with clause for P in its body.
7718 (Has_Limited_With_Clause): New routine.
7719 (Has_With_Clause): New routine.
7721 2007-08-16 Ed Schonberg <schonberg@adacore.com>
7723 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
7724 generic for an enclosing instance is a global reference, even though
7725 its scope is the enclosing instance.
7727 2007-08-16 Gary Dismukes <dismukes@adacore.com>
7728 Javier Miranda <miranda@adacore.com>
7730 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
7731 initialize a limited object.
7732 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
7734 Make sure Has_Complex_Representation is inherited by derived type.

7741 2007-08-16 Ed Schonberg <schonberg@adacore.com>
7743 * sem_disp.adb (Check_Dispatching_Operation): If the operation
7744 implements an operation inherited from a progenitor interface, verify
7745 that they are subtype-conformant.

7748 Bob Duff <duff@adacore.com>
7749 Nicolas Setton <setton@adacore.com>
7751 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
7752 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
7753 the statement which is being resolved comes from a predefined library
7754 unit, all non-predefined library interpretations are skipped.
7755 (Resolve_Op_Concat): If string concatenation was folded in the parser,
7756 but the "&" is user defined, give an error, because the folding would
7759 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
7760 the parser has folded a long sequence of concatenations of string
7763 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
7764 and "JMP_BUF" variables as artificial.
7765 (N_String_Literal): Do not use alloca for very long string literals. Use
7766 xmalloc/free instead. Otherwise the stack might overflow.
7768 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
7771 2007-08-16 Vincent Celier <celier@adacore.com>
7773 * vms_conv.adb (Process_Argument): Ensure that project related options
7774 are not put in the -cargs section when using GNAT COMPILE.
7776 2007-08-16 Robert Dewar <dewar@adacore.com>
7778 * gnat_ugn.texi: Add note on preprocessing (output file not written)
7780 2007-08-16 Thomas Quinot <quinot@adacore.com>

7795 * a-calend-vms.adb, a-calend.adb ("+", "-", Add, Subtract): Remove
7796 calls to Check_Within_Time_Bounds.
7797 ("+", "-", Add, Subtract): Remove calls to Check_Within_Time_Bounds.

7808 switch -gnatyS. Enable -gnatyS in GNAT style check mode
7810 2007-08-14 Robert Dewar <dewar@adacore.com>
7811 Ed Schonberg <schonberg@adacore.com>
7813 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
7814 Suppress unmodified in-out parameter warning in some cases
7815 This patch is a also fairly significant change to the way suppressible
7818 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
7819 needed for access to concurrent record types generated by the expander.
7820 (Generate_Range_Check): When generating a temporary to capture the
7821 value of a conversion that requires a range check, set the type of the
7822 temporary before rewriting the node, so that the type is always
7823 properly placed for back-end use.
7824 (Apply_Float_Conversion_Check): Handle case where the conversion is
7826 (Get_Discriminal): Code reformatting. Climb the scope stack looking
7827 for a protected type in order to examine its discriminants.

7831 Ed Schonberg <schonberg@adacore.com>
7832 Thomas Quinot <quinot@adacore.com>
7834 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
7835 a-stwisu.adb, a-strsup.adb: Fix warnings for range
7836 tests optimized out.
7838 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
7839 (Get_Allocator_Final_List): For the case of an anonymous access type
7840 that has a specified Associated_Final_Chain, do not go up to the
7842 (Expand_N_Type_Conversion): Test for the case of renamings of access
7843 parameters when deciding whether to apply a run-time accessibility
7845 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
7846 aggregate code before allocator, and ahead of declaration for
7847 temporary, to prevent access before elaboration when the allocator is
7848 an actual for an access parameter.
7849 (Expand_N_Type_Conversion): On an access type conversion involving an
7850 access parameter, do not apply an accessibility check when the
7851 operand's original node was an attribute other than 'Access. We now
7852 create access conversions for the expansion of 'Unchecked_Access and
7853 'Unrestricted_Access in certain cases and clearly accessibility should
7854 not be checked for those.
7856 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
7857 includes a type conversion of a packed component that has been expanded,
7858 recover the original expression for the object, and use this expression
7859 in the post-call assignment statement, so that the assignment is made
7860 to the object and not to a back-end temporary.
7861 (Freeze_Subprogram): In case of primitives of tagged types not defined
7862 at the library level force generation of code to register the primitive
7863 in the dispatch table. In addition some code reorganization has been
7864 done to leave the implementation clear.
7865 (Expand_Call): When expanding an inherited implicit conversion,
7866 preserve the type of the inherited function after the intrinsic
7867 operation has been expanded.
7869 * exp_ch2.ads, exp_ch2.adb
7870 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
7871 of an entry formal appearing in an assignment statement does not assign
7873 (Expand_Current_Value): Instead of calling a routine to determine
7874 whether the prefix of an attribute reference should be optimized or
7875 not, prevent the optimization of such prefixes all together.
7877 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
7878 component whose prefix is known to be of an access type is an implicit
7879 dereference and does not assign to the prefix.
7881 2007-08-14 Ed Schonberg <schonberg@adacore.com>
7882 Robert Dewar <dewar@adacore.com>
7884 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
7885 itype is visited, make an entry into table to link associated node and
7887 Add comments and correct harmless error in Build_NCT_Hash_Tables
7888 (Array_Aggr_Subtype): Associate each itype created for an index type to
7889 the corresponding range construct, and not to the aggregate itself. to
7890 maintain a one-to-one correspondence between itype and its associated
7891 node, to prevent errors when complex expression is copied.
7892 Fix mishandling of multiple levels of parens
7894 * sem_aggr.adb: Create a limited view of an incomplete type, to make
7895 treatment of limited views uniform for all visible declarations in a
7896 limited_withed package.
7897 (New_Copy_Tree): If hash table is being used and itype is visited,
7898 make an entry into table to link associated node and new itype.
7899 (Resolve_Record_Aggregate): Do not add an others box association for a
7900 discriminated record component that has only discriminants, when there
7901 is a box association for the component itself.
7903 * par-ch4.adb: Fix mishandling of multiple levels of parens
7905 2007-08-14 Robert Dewar <dewar@adacore.com>
7907 * comperr.adb: Fix problem with suppressing warning messages from gigi

7911 (Write_Eol_Keep_Blanks): New procedure to write a line, including
7912 possible trailing spaces.
7913 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
7914 Fix problem with suppressing warning messages from back end
7915 Improve handling of deleted warnings
7918 Fix problem with suppressing warning messages from back end
7919 Handle setting of Static_Dispatch_Tables flag.

7938 Javier Miranda <miranda@adacore.com>
7939 Gary Dismukes <dismukes@adacore.com>
7941 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
7942 to make treatment of limited views uniform for all visible declarations
7943 in a limited_withed package.
7944 Improve warnings for in out parameters
7945 (Set_Related_Interaface/Related_Interface): Allow the use of this
7946 attribute with constants.
7947 (Write_Field26_Name): Handle attribute Related_Interface in constants.
7948 Warn on duplicate pragma Preelaborable_Initialialization
7950 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
7951 generation of a freezing node to ensure proper management of null
7952 excluding access types in the backend.
7953 (Create_Extra_Formals): Test base type of the formal when checking for
7954 the need to add an extra accessibility-level formal. Pass the entity E
7955 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
7956 originally being done in a couple of cases), to ensure that the
7957 Extra_Formals list gets set on the entity E when the first entity is
7959 (Conforming_Types): Add missing calls to Base_Type to the code that
7960 handles anonymous access types. This is required to handle the
7961 general case because Process_Formals builds internal subtype entities
7962 to handle null-excluding access types.
7963 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
7964 functions that need it, even when not marked Requires_Overriding.
7965 Improve warnings for in out parameters
7966 (Analyze_Function_Return): Warn for disallowed null return
7967 Warn on return from procedure with unset out parameter
7968 Ensure consistent use of # in error messages
7969 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
7970 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
7971 the implicit conversion of the expression done for anonymous access
7972 types. This is required to generate the code of the null excluding
7973 check (if required).
7975 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
7976 A formal parameter is never publicly referenceable outside of its body.
7977 (Check_References): For an unreferenced formal parameter in an accept
7978 statement, use the same warning circuitry as for subprogram formal
7980 (Warn_On_Unreferenced_Entity): New subprogram, taken from
7981 Output_Unreferenced_Messages, containing the part of that routine that
7982 is now reused for entry formals as described above.
7983 (Goto_Spec_Entity): New function
7984 (Check_References): Do not give IN OUT warning for dispatching operation
7985 Improve warnings for in out parameters
7986 (Test_Ref): Check that the entity is not undefinite before calling
7987 Scope_Within, in order to avoid infinite loops.
7988 Warn on return from procedure with unset out parameter
7989 Improved warnings for unused variables

7993 Gary Dismukes <dismukes@adacore.com>
7995 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
7996 (Expand_N_Attribute_Reference): Further unify the handling of the
7997 three forms of access attributes, using common code now for all three
7998 cases. Add a test for the case of applying an access attribute to
7999 an explicit dereference when the context is an access-to-interface
8000 type. In that case we need to apply the conversion to the prefix
8001 of the explicit dereference rather than the prefix of the attribute.
8002 (Attribute_Version, UET_Address): Set entity as internal to ensure
8003 proper dg output of implicit importation.
8004 (Expand_Access_To_Type): Removed.
8005 (Expand_N_Attribute_Reference): Merge the code from the three cases
8006 of access attributes, since the processing is largely identical for
8007 these cases. The substantive fix here is to process the case of a
8008 type name prefix (current instance case) before handling the case
8009 of interface prefixes.

8014 Robert Dewar <dewar@adacore.com>
8016 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
8017 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
8018 type that is an anonymous access to controlled object, establish
8019 an associated finalization chain to avoid corrupting the global
8020 finalization list when a dynamically allocated object designated
8021 by such a component is deallocated.
8022 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
8023 functions that need it, even when not marked Requires_Overriding.
8024 (Initialize_Tag): Replace call to has_discriminants by call to
8025 Is_Variable_Size_Record in the circuitry that handles the
8026 initialization of secondary tags.

8121 * exp_util.ads, exp_util.adb:
8122 This patch replaces a number of occurrences of explicit tests for N_Null
8123 with calls to Known_Null. This improves tracking of null values, since
8124 Known_Null also catches null constants, and variables currently known to
8125 be null, so we get better tracking.
8126 (Ensure_Defined): create an itype reference only in the scope of the
8128 (Side_Effect_Free): A selected component of an access type that
8129 denotes a component with a rep clause must be treated as not

8131 value may be affected by a renaming.
8132 (Expand_Subtype_From_Expr): For limited objects initialized with build
8133 in place function calls, do nothing; otherwise we prematurely introduce
8134 an N_Reference node in the expression initializing the object, which

8136 the called function. Bug found working in the new patch for statically
8137 allocated dispatch tables.
8138 (Is_Library_Level_Tagged_Type): New subprogram.

8142 attributes properly to compute the constraint on the resulting aggregate
8145 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
8146 class-wide type whose base type is an incomplete private type, leave
8147 class-wide type unfrozen so that freeze nodes can be generated
8148 properly at a later point.
8149 (Freeze_Entity, array case): Handle case of pragma Pack and component
8150 size attributre clause for same array.

8799 operations in Derive_Subprograms.
8800 (Collect_Previous_Instances): new procedure within of
8801 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
8802 unit being loaded, to ensure that the generation of global symbols is
8803 consistent in different compilation modes.
8804 (Is_Tagged_Ancestor): New function testing the ancestor relation that
8805 takes progenitor types into account.
8806 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
8807 traversing over the primitives of the formal and actual types to locate
8808 any abstract subprograms of the actual type that correspond to a
8809 nonabstract subprogram of the formal type's ancestor type(s), and issue
8810 an error if such is found.
8811 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
8812 Instantiate_Package_Body, Instantiate_Subprogram_Body):
8813 Remove bogus guard around calls to Inherit_Context.

8823 parameter to determine whether operation applies to the prefix.
8824 (Complete_Object_Operation): If actual has an access type and
8825 controlling formal is not an in_parameter, reject the actual if it is
8826 an access_to_constant type.
8827 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
8828 type, the candidate operations are found in the scope of declaration of
8829 the type, because the type has no primitive subprograms.
8830 (Analyze_Selected_Component): If prefix is class-wide, and root type is
8831 a private extension, only examine visible components before trying to
8832 analyze as a prefixed call.
8833 Change Entity_List to Type_To_Use, for better readability.
8834 (Has_Fixed_Op): Use base type when checking whether the type of an
8835 operator has a user-defined multiplication/division

8843 formal At_Any_Place indicating, when True, that we want to test for
8844 availability of the stream attribute at any place (as opposed to the
8845 current visibility context only).
8846 (Missing_Read_Write_Attributes): A stream attribute is missing for the
8847 purpose of enforcing E.2.2(8) only if it is not available at any place.
8848 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
8849 when checking the legality of an extension aggregate in a preelaborable
8850 package. Treat the literal null as a valid default expression in a
8851 component declaration for a type with preelaborable initialization.
8852 A limited interface is a legal progenitor for the designated type of a
8853 remote access to class-wide type.

8867 views that are themselves incomplete types.
8868 Handle interfaces visible through limited-with clauses.
8869 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
8870 subprogram generic actual for which we have generated a renaming.

8878 appear in the subtree to the current allocator if it is not a static
8880 (Resolve_Allocator): Perform cleanup if resolution has determined that
8881 the allocator is not a coextension.
8882 (Resolve): Skip an interpretation hidden by an abstract operator only
8883 when the type of the interpretation matches that of the context.
8884 (Resolve): When looping through all possible interpretations of a node,
8885 do not consider those that are hidden by abstract operators.
8886 (Resolve_Actuals): When verifying that an access to class-wide object
8887 is an actual for a controlling formal, ignore anonymous access to
8888 subprograms whose return type is an access to class_wide type.
8889 (Resolve_Slice): If the prefix of the slice is a selected component
8890 whose type depends on discriminants, build its actual subtype before
8891 applying range checks on the bounds of the slice.
8892 (Valid_Conversion): In an instance or inlined body, compare root types,
8893 to prevent anomalies between private and public views.
8894 (Resolve): Improve error message for ambiguous fixed multiplication
8895 expressions that involve universal_fixed multiplying operations.

8913 extraneous layer of Any wrapping for member label.
8914 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
8915 elabration statements, register the package with the name server
8916 at the beginning, not at the end, of the elaboration statements so
8917 that they can create remote access to subprogram values that designate
8918 remote subprograms from the package.
8920 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
8922 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
8923 values to compute the number of seconds since the Unix Epoc in order to
8924 account for Daylight Savings Time. Perform special processing for dates
8925 that are earlier than the Unix Epoc to obtain a negative number.

9969 make_aligning_type for super-aligned objects allocated from the default
9970 pool. Leave enough room for a pointer before the aligning field, and
9971 store the system's allocator return value there.
9972 (build_call_alloc_dealloc): When releasing a super-aligned object,
9973 retrieve the system's allocator return value from where build_allocator
9974 has stored it, just ahead of the adjusted address we are passed.

10001 (Gen_Output_File_Ada, Gen_Output_File_C): Never use __attribute
10002 ((destructor)) for adafinal, even when switch -a is used.
10003 Do not issue pragma Linker_Destructor for adafinal when switch -a is
10005 (Gen_Object_Files_Options): Add formatting of Linker Options, when
10006 Output_Linker_Option_List is set. Suppress this formatting when
10007 Zero_Formatting is set.
10008 Add case for CLI_Target.
10009 (System_Restrictions_Used): New flag, used to avoid generating with of

10044 (Get_E_Length): Protect against bomb in case scope is standard
10045 (Selected_Range_Checks): If the node to be checked is a conversion to
10046 an unconstrained array type, and the expression is a slice, use the
10047 bounds of the slice to construct the required constraint checks.
10048 Improve NOT NULL error messages
10049 (Apply_Constraint_Check): If the context is a null-excluding access
10050 type, diagnose properly the literal null.

10065 Eric Botcazou <ebotcazou@adacore.com>
10066 Arnaud Charlet <charlet@adacore.com>
10068 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
10069 applicable to types that have the With_Type flag set. Returns the
10070 non-limited view of the type, if available, otherwise the type itself.
10071 For class-wide types, there is no direct link in the tree, so we have
10072 to retrieve the class-wide type of the non-limited view of the Etype.
10073 New attributes Static_Initialization and Static_Elaboration_Desired.
10074 Remove the pragma Thread_Body, and the associated flag
10075 Is_Thread_Body in entities, and all related code.
10076 (Suppress_Value_Tracking_On_Call): New flag
10077 E_Exception has Esize and Alignment fields
10078 (Universal_Aliasing): New function.

10088 (Original_Access_Type): Remove, not needed.
10089 (Root_Type): Handle properly subtypes of class-wide-types.
10092 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
10093 class-wide types visible through limited-with clauses.
10094 (Try_Primitive_Operation): When examining all primitive operations of a
10095 tagged type, do not consider subprograms labeled as hidden unless they
10096 belong to a private generic type with a tagged parent.
10097 (Try_Object_Operation): Extensive rewriting, to handle properly various
10098 overloading cases, when several ancestors may have class-wide operations
10099 that are possible candidates, and when the overloaded functions return
10100 array types and have defaulted parameters so that the call may be
10101 interpreted as an indexing.
10102 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
10103 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
10104 successive actuals before analyzing the call itself.
10105 (Try_Primitive_Operation): A primitive operation is compatible with the
10106 prefix if the prefix has a synchronized type and the type of the formal
10107 is its corresponding record, as can be the case when the primitive
10108 operation is declared outside of the body of the type.
10109 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
10110 perform homonym traversal, looking for class-wide operation matches
10111 (formerly done in statements of Try_Class_Wide_Operation). Matches on
10112 access parameters are now restricted to anonymous access types.
10113 (Mark_Allocator): An allocator with a discriminant association parent is
10115 (Try_One_Prefix_Interpretation): If the type of the object is
10116 incomplete, as can be happen when it is a limited view obtained through
10117 a limited_with_clause, the selected component is not part of a prefixed
10119 (Complete_Object_Operation): Diagnose properly an object that is not
10120 aliased when the corresponding controlling formal is an access
10122 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
10123 ambiguous calls in prefixed notation, where two primitives differ only
10124 in that the controlling argument of one is an access parameter.
10126 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
10127 whether a function that returns an unconstrained type can be inlined.
10128 (Process_Formals): Diagnose properly the illegal use of an incomplete
10129 type in the profile of an access_to_subprogram declaration.
10130 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
10131 operations are attached to the corresponding record.
10132 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
10133 When processing a primitive of a concurrent type which implements an
10134 interface change the type of all controlling formals to that of the
10135 corresponding record type.
10136 (Check_Synchronized_Overriding): Relax the conditional logic when trying
10137 to determine the tagged type to which a primitive belongs.
10138 (Check_Conventions): Capture condition to ignore a primitive operation
10139 (which is shared between the loop in Check_Conventions and the one in
10140 Check_Convention) in a new local function Skip_Check.
10141 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
10142 confusion with Check_Conventions' own Prim_Op local variable.
10143 (Create_Extra_Formals): Test for a tagged result type rather than a
10144 controlling result when determining whether to add a BIP_Alloc_Form
10145 formal and a BIP_Final_List formal to the function.
10146 (Check_Conformance); For parameters that are anonymous access types,
10147 subtype conformance requires that the not null and the constant
10148 indicators must match
10149 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
10150 to retrieve the appropriate type when processing a concurrent type
10151 declared within a generic. Minor comment reformatting. Change invocation
10152 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
10154 (Analyze_Subprogram_Body): If the return type of a function is an
10155 anonymous access to the limited view of a class-wide type, and the
10156 non-limited view of the type is available, update the type of the
10157 function so that code can be generated.
10158 (Process_Formals): In case of access-subtype itype whose designated
10159 type is also an itype (situation that happens now with access to
10160 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
10161 attribute to avoid backend problems.
10162 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
10163 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
10164 anonymous types' designated types are same before testing
10165 Subtypes_Statically_Match.
10166 (Create_Extra_Formals): Test for a named access parameter that is a
10167 controlling formal as an additional condition for adding an
10168 accessibility level formal. This can occur in the subp type created for
10169 dispatching calls in Expand_Dispatching_Call, and allows calling
10170 Create_Extra_Formals from that procedure rather than special-casing the
10171 extra formals there.
10172 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
10173 when the function has a controlling result.
10174 (Check_Returns): Add much more knowledge of the optimization of local
10175 raise statements to gotos, to retain proper warnings in this case.
10176 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
10177 nodes when looking for last statement.
10179 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
10180 class-wide types visible through limited with clauses.
10181 (Add_One_Interp): If the operands are anonymous access types, the
10182 predefined operator on universal_access is immediately visibles
10183 (Find_Unique_Type): Handle anonymous access to subprogram types just as
10184 other anonymous access types.
10185 (Disambiguate): Take into account CIL convention.
10186 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
10188 2007-06-06 Robert Dewar <dewar@adacore.com>
10190 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,

10192 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
10193 Fix lower bound of tables.
10196 * nlists.adb: Ditto.
10197 (Prev_Node, Next_Node): Change index type to Int so that it properly
10198 covers the range First_Node_Id - 1 up.
10200 2007-06-06 Javier Miranda <miranda@adacore.com>
10201 Ed Schonberg <schonberg@adacore.com>
10202 Bob Duff <duff@adacore.com>
10203 Hristian Kirtchev <kirtchev@adacore.com>
10205 * exp_aggr.ads, exp_aggr.adb:
10206 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
10207 in extension aggregates.
10208 (Flatten): Other conditions being met, an aggregate is static if the
10209 low bound given by component associations is different from the low
10210 bound of the base index type.
10211 (Packed_Array_Aggregate_Handled): If the component type is itself a
10212 packed array or record, the front-end must expand into assignments.
10213 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
10214 Init_Pr, instead of Ancestor_Is_Expression.
10215 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
10216 coextension chain root, either generate a list controller or use the
10217 already existing one.
10218 (Static_Array_Aggregate): New procedure to construct a positional
10219 aggregate that can be handled by the backend, when all bounds and
10220 components are compile-time known constants.
10221 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
10222 types covering interface types into assignments.
10223 (Replace_Type): move to Build_Record_Aggr_Code.
10224 (Expand_Record_Aggr_Code): if the target of the aggregate is an
10225 interface type, convert to the definite type of the aggregate itself,
10226 so that needed components are visible.
10227 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
10228 components and the context is an extended return statement do not
10229 create a transient block for it, to prevent premature finalization
10230 before the return is executed.
10231 (Gen_Assign): Do not generate a call to deep adjust routine if the
10232 component type is itself an array of controlled (sub)-components
10233 initialized with an inner aggregate.
10234 (Component_Check): New name for Static_Check. This name is now more
10235 appropriate, and documentation is added which was missing.
10236 (Component_Check): Add test for bit aligned component value
10237 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
10238 Tagged_Comps, name is more appropriate given added function below.
10239 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
10241 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
10242 Javier Miranda <miranda@adacore.com>
10243 Robert Dewar <dewar@adacore.com>
10245 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
10246 Terminated: Add unchecked type conversion from System.Address to
10247 System.Tasking.Task_Id when calling the predefined primitive
10249 Disable new Ada 05 accessibility check for JVM.NET targets, which
10250 cannot be implemented in a practical way.
10251 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
10252 the sources always references the tag of the actual object. Therefore,
10253 if 'Tag is applied in the sources to class-wide interface objects we
10254 generate code that displaces "this" to reference the base of the object.
10255 (Expand_N_Attribute_Reference, case Size): Return specified size if
10256 known to front end.
10257 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
10258 has code that displaces the pointer of the object to manage interface
10259 types. However this code must not be executed when the prefix is a
10260 subprogram. This bug caused the wrong expansion of the internally
10261 generated assignment that fills the dispatch table when the primitive
10262 is a function returning a class-wide interface type.
10263 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
10264 Set_Attribute_Name for Name_Unaligned_Valid.
10266 2007-06-06 Ed Schonberg <schonberg@adacore.com>
10267 Gary Dismukes <dismukes@adacore.com>
10269 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
10270 If the initialization is the equivalent aggregate of the initialization
10271 procedure of the type, do not remove it.
10272 (Expand_N_Attribute_Definition_Clause): Exclude access variables
10273 initialized to null from having their expression reset to empty and
10274 note this exception in the comment.

10284 references where the prefix must be a simple name.
10286 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
10287 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
10288 Attribute_Requires_Simple_Name_Prefix.
10289 (Name_Modifies_Prefix): Body of new function.
10290 (Requires_Simple_Name_Prefix): Body of new function.
10291 (Resolve_Attribute, case Access): Improve error message for case of
10292 mismatched conventions.
10293 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
10295 (Analyze_Attribute, case 'Access): If the type of the prefix is a
10296 constrained subtype for a nominal unconstrained type, use its base type
10297 to check for conformance with the context.
10298 (Resolve_Attribute): Remove test of the access type being associated
10299 with a return statement from condition for performing accessibility
10300 checks on access attributes, since this case is now captured by
10301 Is_Local_Anonymous_Access.
10302 (Analyze_Access_Attribute): Set Address_Taken on entity
10303 (Analyze_Attribute, case Address): Set Address_Taken on entity
10304 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
10305 validating an access attribute whose prefix is a current instance.
10306 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
10307 applied to dispatching operations, if freezing is required then we set
10308 the attribute Has_Delayed_Freeze in the prefix's entity.
10309 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
10310 current scope if access of local subprogram taken
10311 (Analyze_Access_Attribute): Check legality of self-reference even if the
10312 expression comes from source, as when a single component association in
10313 an aggregate has a box association.
10314 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
10315 the prefix if it is a protected operation and the attribute is
10316 Unrestricted_Access.
10317 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
10318 reference to the base type of the context, to force a constraint check
10319 when the context is an access subtype with an explicit constraint.
10320 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
10321 node is rewritten as an interface conversion. leave unanalyzed after
10322 resolution, to ensure that type checking against the context will take

10326 Javier Miranda <miranda@adacore.com>
10327 Robert Dewar <dewar@adacore.com>
10329 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
10330 wrapper when the full view of the controlling type of an inherited
10331 function that dispatches on result implements interfaces.
10332 (Expand_N_Object_Declaration): In cases where the type of the
10333 declaration is anonymous access, create finalization list for it.
10334 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
10335 if the object has no explicit initialization, to match description of
10336 functionality of pragam Persistent_BSS.
10337 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
10338 new function to build static aggregates, to replace initialization call
10339 when static initialization is desired.
10340 (Freeze_Type): Generate a list controller for an access type whenever
10341 its designated type has controlled anonymous access discriminants.
10342 (Build_Equivalent_Aggregate): New procedure to compute a static
10343 aggregate to be used as default initialization for composite types,
10344 instead of a generating a call to the initialization procedure for the
10346 (Build_Initialization_Call): When available, replace a call to the
10347 initialization procedure with a copy of the equivalent static aggregate
10349 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
10350 declarations for objects of a class-wide interface type, rather than
10351 just identifiers, to prevent visibility problems.
10352 (Expand_N_Object_Declaration): When expanding the declaration for an
10353 object of a class-wide interface type, preserve the homonym chain of
10354 the original entity before exchanging it with that of the generated
10355 renaming declaration.
10356 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
10357 active, because there is no way to handle the exception.
10358 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
10359 to do a minimum decoration of the Access_Disp_Table list.
10360 (Expand_Record_Controller): Avoid the addition of the controller between
10361 the component containing the tag of a secondary dispatch table and its
10362 adjacent component that stores the offset to the base of the object.
10363 This latter component is only generated when the parent type has
10364 discriminants ---documented in Add_Interface_Tag_Components).
10365 (Apply_Array_Size_Check): Removed, no longer needed.
10366 (Expand_N_Full_Type_Declaration): If the type has anonymous access
10367 components, create a Master_Entity for it only if it contains tasks.
10368 (Build_Init_Procedure): Suppress the tag assignment compiling under
10370 (Freeze_Record_Type): Remove code associated with creation of dispatch
10372 (Init_Secondary_Tags): Update type of actuals when generating calls to
10373 Ada.Tags.Set_Offset_To_Top
10374 (Stream_Operation_OK): Disable use of streams compiling under no
10376 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
10377 if Has_Init_Expression set.
10378 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
10379 Register_Primitive, which provides the same functionality.
10380 (Requires_Init_Proc): Return false in case of interface types.
10381 (Add_Secondary_Tables): Use the new attribute Related_Interface to
10383 (Predefined_Primitive_Freeze): Do not assume that an internal entity
10384 is always associated with a predefined primitive because the internal
10385 entities associated with interface types are not predefined primitives.
10386 Therefore, the call to Is_Internal is replaced by a call to the
10387 function Is_Predefined_Dispatching_Operation.
10388 (Make_Eq_If): When generating the list of comparisons for the
10389 components of a given variant, omit the controller component that is
10390 present if the variant has controlled components.

10393 Hristian Kirtchev <kirtchev@adacore.com>
10394 Bob Duff <duff@adacore.com>
10396 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
10397 handle the creation of finalization lists and calls for nested
10398 coextensions when the root of the chains is part of a return statement.
10399 (Inside_A_Return_Statement): New function inside Complete_Coextension_
10401 (Expand_Record_Equality): Skip components that are interface types.
10402 (Displace_Allocator_Pointer): Add missing support for interface subtypes
10403 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
10404 with Rewrite_Coextension. Change the condition for detecting coextension
10406 (Is_Local_Access_Discriminant): Removed.
10407 (Rewrite_Coextension): New routine which rewrites a static coextension
10408 as a temporary and uses its unrestricted access in the construction of
10410 (Complete_Coextension_Finalization): New routine. Generate finalization
10411 attachment calls to all delayed coextensions.
10412 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
10413 the allocator is not a coextension itself and has delayed coextensions.
10414 If the current allocator is controlled, but also a coextension, delay
10415 the generation of the finalization attachment call.
10416 Rename local variable "Node" to "Nod" in order to avoid confusion with
10418 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
10419 limited types that are not inherently limited. Such an allocator is
10420 illegal, but is generated by the expander for a return statement, to
10421 copy the result onto the secondary stack. This is the only case where a
10422 limited object can be copied. Generate code to displace the pointer
10423 to the object if the qualified expression is a class-wide interface
10424 object. Such displacement was missing and hence the copy of the object
10426 (Apply_Accessibility_Check): Handle allocated objects initialized in
10428 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
10429 and Expand_Allocator_Expression. Allocating class-wide interface objects
10430 this routine displaces the pointer to the allocated object to reference
10431 the component referencing the corresponding secondary dispatch table.
10432 Expand_Allocator_Expression): Add missing support to allocate class-wide
10433 interface objects initialized with a qualified expression.
10434 (Get_Allocator_Final_List): Test for an anonymous access type that is a
10435 function result type, and use the finalization list associated with the
10436 function scope in that case (such an anonymous type should not be
10437 treated like an access parameter's type).
10439 2007-06-06 Ed Schonberg <schonberg@adacore.com>
10440 Gary Dismukes <dismukes@adacore.com>
10441 Javier Miranda <miranda@adacore.com>
10443 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
10444 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
10445 required exception handler.
10446 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
10447 properly the case of a function whose return type is a limited
10448 class-wide interface type. Modify the code of the accessibility
10449 check to handle class-wide interface objects. In this case we need to
10450 displace "this" to reference the primary dispatch table to get access
10451 to the TSD of the object (to evaluate its accessibility level).
10452 (Expand_N_Extended_Return_Statement): Test for a tagged result type
10453 rather than a controlling result as one of the conditions for
10454 generating tests of the implicit BIP_Alloc_Form formal. The
10455 initialization assignment is also handled according to whether the
10456 result is tagged instead of controlling.
10457 In the case where the init assignment is inserted in the "then" part of
10458 the allocation conditional, rewrite the target to be a dereference of
10459 the implicit BIP_Object_Access formal.
10460 If the returned value is unconstrained and created on the secondary
10461 stack, mark the enclosing block and function so that the secondary
10462 stack is not reclaimed on return.
10463 Treat returns from functions with controlling results similarly to
10464 returns from functions with unconstrained result subtypes.
10465 If the object returned is unconstrained, and an allocator must be
10466 created for it, analyze the allocator once the block for the extended
10467 return is installed, to ensure that finalizable components
10468 of the expression use the proper finalization list. Guard the call to
10469 Move_Final_List with a check that there is something to finalize.
10470 (Make_Tag_Ctrl_Assignment): Use "old" handling
10471 of controlled type assignment for virtual machines, since new code uses
10472 unsupported features (such as direct access to bytes in memory).
10474 2007-06-06 Gary Dismukes <dismukes@adacore.com>
10475 Ed Schonberg <schonberg@adacore.com>
10477 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
10478 accessibility actual, check for the case of an aliased object that has
10479 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
10480 we fall into processing for the attribute rather than the name of the
10482 (Expand_Inline_Call): If an actual is a literal, and the corresponding
10483 formal has its address taken in the body, create a temporary to capture
10484 value. If the return type is a limited interface, do not treat the
10485 return value as Controlled.
10486 (Is_In_Place_Function): If the return type is a limited interface,
10487 treat as returning in place. The actual returned object may not always
10488 be limited, but the caller has to assume that it is returned in place.
10489 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
10490 context of an allocator, use the correct finalization chain (that is,
10491 the chain belonging to the access type, rather than the chain belonging
10492 to the current scope).
10493 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
10494 result type rather than a controlling result as a precondition for
10495 adding an allocation form actual to a build-in-place call.
10496 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
10497 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
10498 primitive in the dispatch tables. This work is now done by Make_DT when
10499 the type is frozen.
10500 (Register_Predefined_DT_Entry): Removed.
10501 (Add_Return): If end label is not present, use sloc of last statement
10502 for generated return statement in procedure, for better gdb behavior
10504 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
10505 object address nodes to ensure proper processing by routines like
10507 (Expand_Call): Fix generation of validity check for parameter
10508 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
10509 the allocation form parameter if the result subtype is constrained,
10510 except when the function has a controlling result.
10511 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
10512 rather than Is_Controlled and Has_Controlled_Component, since we want to
10513 include class-wide result types in this treatment. Also test for a
10514 controlling result, since that also requires passing a finalization
10516 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
10517 even when the result subtype is constrained, to handle calls involving
10518 controlling results.
10519 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
10520 is now called even when the result subtype is constrained, to handle
10521 calls involving controlling results.
10522 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
10523 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
10524 now performs the test).
10525 (Make_Build_In_Place_Call_In_Object_Declaration):
10526 Add_Alloc_Form_Actual_* is now called even when the result subtype is
10527 constrained, to handle calls involving controlling results.
10528 (Add_Return): Accomodate rewritten pattern from local raise to goto
10529 transformation, so that we still recognize an transfer statement
10530 and do the right thing here in that case.
10531 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
10532 and end of subprogram code.
10533 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
10534 support for primitives that are functions (without formals) with a
10535 controlling result.
10536 (Inherited_From_Formal): If the actual subtype has not generic parent
10537 type, it is not an actual for a formal derived type, and there is no
10538 operation to inherit from the formal.
10540 2007-06-06 Ed Schonberg <schonberg@adacore.com>
10541 Thomas Quinot <quinot@adacore.com>
10543 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
10544 inserted cleanup code appropriately for GDB use.
10545 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
10546 exception handler for Deep_Adjust or Deep_Finalize.
10547 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
10548 Raise_From_Controlled_Operation is available, use a call to that
10549 subprogram instead of a plain "raise Program_Error" node to raise
10550 Program_Error if an exception is propagated from an Adjust or Finalize
10552 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
10553 appears in the optional statement list of a triggering alternative, the
10554 scope actions can be inserted directly there, and not in the list that
10555 includes the asynchronous select itself.

10561 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
10562 generated exception handler appropriately when debugging generated code.
10563 Deal properly with No_Exception_Propagation restriction mode.
10564 (Expand_N_Abort_Statement): Add an unchecked type conversion from
10565 System.Address to System.Tasking.Task_Id when processing the result of
10566 the predefined primitive _disp_get_task_id.
10567 (Expand_N_Asynchronous_Select): Clarify comment.
10568 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
10569 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
10570 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
10571 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
10572 privals and for generated call to Complete_Entry_Body, for better gdb
10574 (Copy_Result_Type): Utility to construct a parameter and result profile
10575 for protected functions whose return type is an anonymous access to
10577 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
10579 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
10580 point when the local-raise-to-goto transformation has taken place.
10582 2007-06-06 Javier Miranda <miranda@adacore.com>
10583 Nicolas Setton <setton@adacore.com>
10585 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
10586 functionality when the backend is generating code.
10587 Otherwise any serious error
10588 reported by the backend calling the frontend routine Error_Msg
10589 changes the Compilation_Mode to Check_Semantics, disables the
10590 functionality of this routine and causes the generation of
10591 spureous additional errors.
10593 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
10594 debugging information now generated by the compiler for fat-pointer
10596 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
10598 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
10600 2007-06-06 Thomas Quinot <quinot@adacore.com>
10602 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
10603 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
10604 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
10605 For a remote call to a function with a classwide return type, apply an
10606 E.4(18) check to the returned value.
10607 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
10608 stream attributes of the designated type of an RACW, as they are not
10609 dispatching primitive operations.
10611 2007-06-06 Geert Bosch <bosch@adacore.com>
10613 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
10615 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
10617 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
10618 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
10620 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
10622 2007-06-06 Javier Miranda <miranda@adacore.com>
10624 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
10625 attribute compiling package Ada.Tags under No_Run_Time_Mode.
10627 2007-06-06 Javier Miranda <miranda@adacore.com>
10629 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
10630 deallocation of class-wide interface objects.
10631 (Expand_Dispatching_Constructor_Call): Take into account that if the
10632 result of the dispatching constructor is an interface type, the
10633 function returns a class-wide interface type; otherwise the returned
10634 object would be actual. The frontend previously accepted returning
10635 interface types because Expand_Interface_Actuals silently performed
10636 the management of the returned type "as if" it were a class-wide
10638 (Expand_Dispatching_Constructor_Call): Replace call to
10639 Make_DT_Access_Action by direct call to Make_Function_Call.
10641 2007-06-06 Robert Dewar <dewar@adacore.com>
10642 Ed Schonberg <schonberg@adacore.com>
10644 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
10645 compute masking constant, since we now set Esize properly to the
10647 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
10648 to match the alignment.
10649 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
10650 packed arrays of 8 bits or less.
10652 * freeze.adb (Freeze_Entity): When freezing the formals of a
10653 subprogram, freeze the designated type of a parameter of an access type
10654 only if it is an access parameter.
10655 Increase size of C convention enumeration object
10656 (Freeze_Entity, array type case): Make sure Esize value is properly
10657 adjusted for the alignment if it is known.
10658 (Freeze_Entity, array type case): When checking bit packed arrays for
10659 the size being incorrect, check RM_Size, not Esize.
10660 (Freeze_Record_Type): Check for bad discriminated record convention
10661 (In_Exp_Body): Return true if the body is generated for a subprogram
10662 renaming, either an attribute renaming or a renaming as body.
10663 (Check_Itype): If the designated type of an anonymous access component
10664 is a non-protected subprogram type, indicate that it is frozen, to
10665 prevent out-of-scope freeze node at some subsequent call.
10666 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
10667 only if the subprogram is neither imported nor exported, as well as the
10668 NCA descriptor class if the subprogram is exported.

10673 Gary Dismukes <dismukes@adacore.com>
10675 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
10676 default initialization on an imported object, when there is no
10677 initialization call generated for it.
10678 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
10681 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
10682 Static_Elaboration_Desired.
10683 Remove pragma Thread_Body.
10684 Implement a new pragma No_Body
10685 Removes the Explicit_Overriding pragma
10686 Remove Optional_Overriding pragma
10687 (Prag): Deal with Universal_Aliasing.
10688 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
10689 Pragma_CIL_Constructor): New names.
10691 * sem_cat.adb (Validate_Object_Declaration): An initialization that
10692 uses the equivalent aggregate of a type must be treated as an implicit
10694 (Get_Categorization): Check a unit for pragma Preelaborate only if it
10695 has none of the other categories.
10696 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
10697 to apply Import to an object renaming declaration.
10699 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
10700 from a C++ class should be declared as limited and that it will be
10701 considererd limited.
10702 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
10703 should be declared as limited and that it will be considererd limited.
10704 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
10705 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
10706 (Analyze_Pragma): Deal with Universal_Aliasing.
10707 (Sig_Flags): Likewise.
10708 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
10709 (Overflow_Checks_Unsuppressed): New flag.
10710 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
10711 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
10712 case of JVM or .NET targets, and compiling user code.
10713 Add debugging convenience routine rv
10715 2007-06-06 Robert Dewar <dewar@adacore.com>
10717 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
10718 are interface type.
10719 (Build_Elementary_Input_Call): For floating-point use right type in the
10720 absence of strange size or stream size clauses.
10721 (Build_Elementary_Write_Call): Same fix
10722 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
10723 set to value that does not match base type size.
10725 2007-06-06 Ed Schonberg <schonberg@adacore.com>
10727 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
10728 object of a limited type can be initialized with a call to a function
10729 that returns in place. If the limited type has unknown discriminants,
10730 and the underlying type is a constrained composite type, build an actual
10731 subtype from the function call, as is done for private types.
10732 (Side_Effect_Free): An expression that is the renaming of an object or
10733 whose prefix is the renaming of a object, is not side-effect free
10734 because it may be assigned through the renaming and its value must be
10735 captured in a temporary.
10736 (Has_Controlled_Coextensions): New routine.
10737 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
10738 as is done for other limited types.
10739 (Non_Limited_Designated_Type): new predicate.
10740 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
10742 Remove all handling of with_type clauses.
10744 * par-ch10.adb: Remove all handling of with_type clauses.

12559 build-in-place functions with result type with controlled parts.
12560 Remove no longer used entities.
12562 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
12563 longer needed, because the full type is now limited, and therefore a
12564 pass-by-reference type.
12565 (Foreign_Task_Level): New constant.
12567 * s-tassta.ads, s-tassta.adb (Move_Activation_Chain): New procedure to

12600 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
12601 causes the error message for the ambiguous "X'Access = Y'Access" and
12602 "X'Unrestricted_Access = Y'Access" and so forth to match.
12603 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
12604 now that anonymous access to protected operations have their own kind.

12610 attempt to derive from a synchronized tagged type.
12611 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
12612 type, inherit the class-wide type already created, because it may
12613 already have been used in a self-referential anonymous access component.
12614 (Mentions_T): Recognize self-referential anonymous access components
12615 that use (a subtype of) the class-wide type of the enclosing type.

12617 Derived_Type for Prev formal on call to
12618 Check_Anonymous_Access_Components rather than Empty.

12669 as the second switch, after -c.
12670 (Compile_Sources): Allow compilation of Annex J renames without -a
12671 (Is_In_Object_Directory): Check if the ALI file is in the object
12672 even if there is no project extension.

12674 gnatbind if the ALI file effectively exists.
12675 (Initialize): Add the directory where gnatmake is invoked in front of
12676 the path if it is invoked from a bin directory, even without directory

12701 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
12702 when -gnatg is not specified.
12703 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
12704 there is no need to generate always a record_definition_node in case
12705 of synchronized interface types.
12706 (SIS_Entry_Active): Initialize global variable to False

12733 discriminant and the type is controlled. do not place on a finalization
12734 list at this point. The proper list will be determined from the

12751 accessibility on class-wide allocators if the allocator occurs at the
12752 same scope level as the allocator's type. The check is guaranteed to
12753 succeed in that case, even when the expression originates from a
12754 parameter of the containing subprogram.
12755 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
12756 under No_Dispatching_Calls restriction. During the semantic analysis
12757 we already notified such violation.
12758 (Tagged_Membership): Constant folding. There is no need to check
12759 the tag at run-time if the type of the right operand is non
12760 class-wide abstract.
12761 Replace call to Is_Ancestor by call to Is_Parent
12762 to support concurrent types with interface types.

12774 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
12775 initialize most the TSD components by means of an aggregate.
12776 Modify the declaration of the object containing the TSD
12777 because we now expand code that has a higher level of abstraction.
12778 The TSD has a discriminant containing the Inheritance Depth Level,
12779 value that is used in the membership test but also to fix the size
12780 of the table of ancestors.
12781 (Expand_Interface_Conversion): Insert function body at the closest place
12782 to the conversion expression, to prevent access-before-elaboration
12783 errors in the backend.

12785 compiling under restriction No_Dispatching_Calls plus code cleanup.
12786 Code reorganization plus removal of calls to Set_Num_Prim_Ops

12810 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
12811 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_

12814 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
12815 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
12816 Build_Set_Prim_Op_Address.
12817 (Get_Remotely_Callable): Subprogram removed.
12818 (Init_Predefined_Interface_Primitives): Replace generation of call to
12819 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
12822 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
12823 First (Parameter_Associations ()) with the call to First_Actual that
12824 returns an actual parameter expression for both named and positional
12827 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
12828 check violation of restriction No_Dispatching_Calls.
12829 (Check_Controlling_Type): A formal of a tagged incomplete type is a
12830 controlling argument.
12832 * exp_util.ads, exp_util.adb (Type_May_Have_Bit_Aligned_Components): Use
12833 First/Next_Component_Or_Discriminant
12834 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
12835 (Find_Implemented_Interface): Removed. All the calls to this subprogram
12836 specify Any_Limited_Interface, and this functionality is already
12837 provided by the function Has_Abstract_Interfaces.
12838 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
12839 support concurrent types implementing interfaces.
12840 (Find_Implemented_Interface): Removed. All the calls to this subprogram
12841 specify kind Any_Limited_Interface, and this functionality is already
12842 provided by the function Has_Abstract_Interfaces.
12843 (Remove_Side_Effects): replace Controlled_Type by
12844 CW_Or_Controlled_Type whenever the issue is related to
12845 using or not the secondary stack.
12847 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
12848 P_Interface_Type_Definition to fulfill the new interface (the formal
12849 Is_Synchronized is no longer required).

12861 anonymous, use finalization list of enclosing dynamic scope.
12862 (Expand_N_Package_Declaration): For a library package declaration
12863 without a corresponding body, generate RACW subprogram bodies in the
12864 spec (just as we do for the task activation call).
12865 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
12866 Is_Abstract_Type. Make sure these are called only when appropriate.
12867 Remove all code for DSP option

12884 Family_Size with 'Cap' set to true.
12885 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
12886 a protected version of an operation declared in the private part of
12887 a protected object, because they may be invoked through a callback.
12888 (Set_Privals): If the type of a private component is an anonymous access
12889 type, do not create a new itype for each protected body.
12890 If the body of a protected operation creates
12891 controlled types (including allocators for class-widetypes), the
12892 body of the corresponding protected subprogram must include a

12896 (Type_Conformant_Parameters): Use common predicate Conforming_Types
12897 to determine whether operation overrides an inherited primitive.
12898 (Build_Wrapper_Spec): Add code to examine the parents while looking
12899 for a possible overriding candidate.
12900 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
12901 hold an actual parameter value since its initialization is separated
12902 from the the declaration. Prevents errors on null-excluding access

12906 Pablo Oliveira <oliveira@adacore.com>
12908 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
12909 Do an Unchecked_Conversion to handle the passage from the Underlying
12910 Type to the Base Type when calling Build_To_Any_Call and
12911 Build_From_Any_Call.
12912 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
12913 E_Constant, depending upon Variable formal.
12914 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
12915 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
12916 parameter that requires an extra constrained parameter, declare
12917 temporary for actual as a variable, not a constant.
12918 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
12919 the unit being compiled is the one that contains the stub type.
12920 Change primitive operation name for the RACW associated with a RAS
12921 from Call to _Call so it cannot clash with any legal identifier.
12922 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
12924 (Append_RACW_Bodies): New subprogram.
12925 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
12926 Add_Receiving_Stubs_To_Declarations functions.
12927 When expanding a package body, this list correspond to the
12928 statements in the HSS at the end of the pacakge.
12929 When expanding a package spec, this list correspond to the
12931 (Add_Receiving_Stubs_To_Declarations): Append the function
12932 registering the receiving stubs at the end of the 'Stmts' list.
12933 (RCI_Package_Locator): Pass the new Version generic formal when
12934 instantiating a RCI_Locator package.
12935 (Build_From_Any_Function): To compute the High bound for an
12936 unconstrained array actual, we add the Low bound with the length.
12937 Thus we must convert the low bound and the length to an appropriate
12938 type before doing the sum.
12939 (Build_Subprogram_Receiving_Stubs, PolyORB):
12940 * Retrieve the extra formals parameters at the
12941 end of the parameter stream.
12942 * Use Move_Any_Value to write back out parameters
12943 after executing the request as it is more efficient
12944 than Copy_Any_Value.
12945 * Build the any containing Extra Formals with the
12946 appropriate typecode.
12947 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
12948 empty Component_List.
12949 (Build_Actual_Object_Declaration): New subprogram. Build and insert into

12961 function with the first not implicit parent type.
12962 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
12963 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
12964 typecode from the Etype. Therefore we retrieve the correct typecode
12965 with a call to Get_Any_Type.
12966 (Copy_Specification): Do controlling formal type substitution based on
12967 Is_Controlling_Formal flag, instead of caller-provided object type.
12968 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
12969 a RACW primitive operation, we might get a subprogram declaration for an
12970 ancestor of the RACW designated type (not for the designated type
12971 itself), in the case where this operation is inherited. In this case we
12972 have no easy means of determining the original tagged type for which
12973 the primitive was declared, so instead we now rely on
12974 Copy_Specification to use the Is_Controlling_Formal flag to determine
12975 which formals require type substitution.

13457 (Analyze_Allocator): Collect all coextensions regardless of the context.
13458 Whether they can be allocated statically is determined in exp_ch4.
13459 (Analyze_Selected_Component): If the prefix is a limited view and the
13460 non-limited view is available, use the non-limited one.
13461 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
13462 therefore illegal), suggest a qualified expression rather than a type
13463 conversion, because a type conversion would be illegal in this context.
13464 (Anayze_Allocator): Trace recursively all nested allocators so that all
13465 coextensions are on the corresponding list for the root. Do no mark
13466 coextensions if the root allocator is within a declaration for a stack-
13467 allocated object, because the access discriminants will be allocated on
13469 (Analyze_Call): Remove restriction on calls to limited functions for the
13470 cases of generic actuals for formal objects, defaults for formal objects
13471 and defaults for record components.
13472 (Analyze_Allocator): Before analysis, chain coextensions on the proper
13473 element list. Their expansion is delayed until the enclosing allocator
13474 is processed and its finalization list constructed.
13475 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
13476 for an operation with the given name among the primitive operations of
13477 the corresponding record type.
13478 (Analyze_Selected_Component): If the prefix is a task type that
13479 implements an interface, and there is no entry with the given name,
13480 check whether there is another primitive operation (e.g. a function)
13482 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
13483 properly the indexing of a function call written in prefix form, where
13484 the function returns an array type, and all parameters of the function
13485 except the first have defaults.
13486 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
13487 the original operands, rather than relocating them, for efficiency and
13488 to work properly when an operand is overloaded.
13489 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
13490 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
13491 (Analyze_Selected_Component): If the prefix is a private extension, only
13492 scan the visible components, not those of the full view.
13493 (Try_Primitive_Operation): If the operation is a procedure, collect all
13494 possible interpretations, as for a function, because in the presence of
13495 classwide parameters several primitive operations of the type can match
13496 the given arguments.

13509 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
13510 out of Analyze_Package_Declaration, because processing must be applied
13511 to package bodies as well, for deferred constants completed by pragmas.
13512 (Analyze_Package_Declaration): When the package declaration being
13513 analyzed does not require an explicit body, call Check_Completion.
13514 (May_Need_Implicit_Body): An implicit body is required when a package
13515 spec contains the declaration of a remote access-to-classwide type.
13516 (Analyze_Package_Body): If the package contains RACWs, append the
13517 pending subprogram bodies generated by exp_dist at the end of the body.
13518 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
13519 Is_Abstract_Subprogram and Is_Abstract_Type.
13520 (Preserve_Full_Attributes): The full entity list is not an attribute
13521 that must be preserved from full to partial view.
13523 * sem_dist.adb (Add_RAS_Dereference_TSS):
13524 Change primitive name to _Call so it cannot clash with any legal
13525 identifier, and be special-cased in Check_Completion.
13526 Mark the full view of the designated type for the RACW associated with
13527 a RAS as Comes_From_Source to get proper view switching when installing
13528 private declarations.
13529 Provite a placeholder nested package body along with the nested spec
13530 to have a place for Append_RACW_Bodies to generate the calling stubs
13531 and stream attributes.
13533 2007-04-06 Ed Schonberg <schonberg@adacore.com>
13534 Robert Dewar <dewar@adacore.com>

13560 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
13561 dereference of a local object R created as a reference to another
13562 object O, use the access level of O.
13563 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
13564 rather than local Same_Formal_Type, to check whether protected operation
13565 overrides an inherited one.
13566 (Same_Formal_Type): New predicate, used when matching signatures of
13567 overriding synchronized operations, to handle the case when a formal
13568 has a type that is a generic actual.
13569 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
13570 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
13571 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
13572 syntactic ambiguities involving indexing of function calls that return
13574 (Abstract_Interface_List): New subprogram that returns the list of
13575 abstract interfaces associated with a concurrent type or a
13576 concurrent record type.
13577 (Interface_Present_In_Parent): New subprogram used to check if a
13578 given type or some of its parents implement a given interface.
13579 (Collect_Abstract_Interfaces): Add support for concurrent types
13580 with interface types.
13581 (Has_Abstract_Interfaces): Add support for concurrent types with
13583 (Is_Parent): New subprogram that determines whether E1 is a parent
13584 of E2. For a concurrent type its parent is the first element of its
13585 list of interface types; for other types this function provides the
13586 same result than Is_Ancestor.
13587 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
13588 (Collect_Synchronized_Interfaces): Removed because the subprogram
13589 Collect_Abstract_Interfaces provides this functionality.
13590 (Collect_Abstract_Interfaces): Minor update to give support to
13591 concurrent types and thus avoid undesired code duplication.
13592 (Get_Subprogram_Entity): Handle entry calls.
13593 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
13595 (Enter_Name): Do not give -gnatwh hiding warning for record component

13611 can be an E_Return_Statement.
13612 (Is_Coextension): New flag for allocators.

13631 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
13632 expression with a COMPOUND_EXPR including the call instead of emitting
13633 the call directly here.
13634 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
13635 high bound is constant and the slice is empty. Tidy.
13636 (tree_transform, case N_Op_Not): Handle properly the case where the
13637 operation applies to a private type whose full view is a modular type.
13638 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
13639 Address_Clause, use the associated Expression as the GNAT tree
13640 representing the choice value to ensure the corresponding GCC tree is
13641 of the proper kind.
13642 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
13643 instead of just the operands, as the base GCC stabilize_reference does.
13644 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
13645 requested; otherwise fail.
13646 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

13903 universal_fixed "*" and "/" operators when they are used in a context
13904 that expects any real type. Also set the type of the node to

13906 (mainly static expression evaluation).
13907 Reword some continuation messages
13908 Add some \\ sequences to continuation messages

13926 anonymous access types.
13927 (Valid_Conversion): For a conversion to a numeric type occurring in an
13928 instance or inlined body, no need to check that the operand type is
13929 numeric, since this has been checked during analysis of the template.

14395 (__gnat_set_globals): Now a dummy function.
14396 (__gnat_handle_vms_condition): Feed adjust_context_for_raise with
14397 mechargs instead of sigargs, as the latter can be retrieved from the

14445 (Set_All_DT_Position): Hidden entities associated with abstract
14446 interface primitives are not taken into account in the check for

14459 (Make_DT): If the ancestor of the type is a CPP_Class and we are
14460 compiling under full ABI compatibility mode we avoid the generation of
14461 calls to run-time services that fill the dispatch tables because under
14462 this mode we currently inherit the dispatch tables in the IP subprogram.
14463 (Write_DT): Emit an "is null" indication for a null procedure primitive.
14464 (Expand_Interface_Conversion): Use an address as the type of the formal

14516 we request a discriminal value only in case of discriminants.
14517 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
14518 assignments where the target subtype is unconstrained and the target
14519 object is a parameter or dereference (other aliased cases are known

14637 (Replace_Self_Reference): New subsidiary of
14638 Make_OK_Assignment_Statement, to replace an access attribute that is a
14639 self-reference into an access to the appropriate component of the

14641 nested at any level.
14642 (Is_Self_Referential_Init): Remove, not needed.

14651 Typ'Acc, where Acc is an access attribute, the expression comes from a
14652 default initialized self-referential component.

14654 that has been derived from several abstract interfaces we must also

14683 subcomponent's enclosing variable is aliased with a constrained subtype.
14684 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
14685 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
14686 an aliased prefix must be known to be constrained in order to use True
14687 for the attribute value, and now it's possible for some aliased views
14688 to be unconstrained.

14703 otherwise we incorrectly register the tag of the interface in the final
14705 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
14706 generate the wrapper if the parent primitive is abstract. This is
14707 required to report the correct error message.
14708 (Expand_N_Subtype_Indication): Do validity checks on range
14709 (Clean_Task_Names): If an initialization procedure includes a call to
14710 initialize a task (sub)component, indicate that the procedure will use

14718 call to build-in-place function and apply Make_Build_In_Place_Call_In_
14719 Object_Declaration to the call.
14720 (Freeze_Type): When the designated type of an RACW was not frozen at the
14721 point where the RACW was declared, validate the primitive operations
14722 with respect to E.2.2(14) when it finally is frozen.
14723 (Build_Initialization_Call,Expand_Record_Controller): Rename
14724 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
14725 return-by-reference has no meaning in Ada 2005.
14726 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
14727 to register tag of the immediate ancestor interfaces in the
14728 run-time structure.
14729 (Init_Secondary_Tags): Moved to the specification to allow the
14730 initialization of extension aggregates with abstract interfaces.
14731 (Build_Master_Renaming): Make public, for use by function declarations
14732 whose return type is an anonymous access type.
14733 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
14734 Insert_List_Before_And_Analyze after the generation of the specs
14735 associated with null procedures.
14736 (Expand_Tagged_Root): Update documentation in its specification.
14737 (Init_Secondary_Tags): Update documentation.
14738 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
14739 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
14740 then generate code to inherit the contents of the dispatch table
14741 directly from the ancestor.
14742 (Expand_Record_Controller): Insert controller component after tags of
14743 implemented interfaces.
14744 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to

14748 declarations for overriding null primitives inherited from interfaces.
14749 (Is_Null_Interface_Procedure): New function in
14750 Make_Null_Procedure_Specs.
14751 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
14752 immediate ancestor of a tagged type is an abstract interface type we
14753 must generate the specification of the predefined primitives associated
14754 with controlled types (because the dispatch table of the ancestor is
14755 null and hence these entries cannot be inherited). This is required to
14756 elaborate well the dispatch table.

14770 the maximum for type T.
14771 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
14772 when the allocator is initialized by a build-in-place call, since the
14773 allocator is already rewritten as a reference to the function result,
14774 and this prevents an unwanted duplication of the function call.
14775 Add with and use of Exp_Ch6.
14776 (Expand_Allocator_Expresssion): Check for an allocator whose expression
14777 is a call to build-in-place function and apply
14778 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
14779 untagged designated types).
14780 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
14781 optimization if source or target is biased.
14782 (Expand_N_Allocator): Add comments for case of an allocator within a
14783 function that returns an anonymous access type designating tasks.
14784 (Expand_N_Allocator): apply discriminant checks for access
14785 discriminants of anonymous access types (AI-402, AI-416)
14787 2006-10-31 Bob Duff <duff@adacore.com>
14788 Robert Dewar <dewar@adacore.com>
14789 Gary Dismukes <dismukes@adacore.com>
14790 Ed Schonberg <schonberg@adacore.com>
14792 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
14794 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
14795 (Expand_N_Assignment_Statement): Call
14796 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
14797 build-in-place function call. Currently, this can happen only for
14798 assignments that come from aggregates.
14799 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
14800 in order to alleviate the upward compatibility introduced by AI-318.
14801 (Expand_N_Extended_Return_Statement): Add support for handling the
14802 return object as a build-in-place result.
14803 (Expand_Non_Function_Return): Implement simple return statements nested
14804 within an extended return.
14805 (Enable_New_Return_Processing): Turn on the new processing of return
14807 (Expand_Non_Function_Return): For a return within an extended return,
14808 don't raise Program_Error, because Sem_Ch6 now gives a warning.
14809 (Expand_N_Extended_Return_Statement): Implement AI-318
14810 (Expand_Simple_Function_Return): Ditto.
14811 (Expand_N_If_Statement): Handle new -gnatwt warning
14812 (Expand_N_Case_Statement): Handle new -gnatwt warning
14813 (Expand_N_Assignment): Handle assignment to the Priority attribute of
14814 a protected object.
14815 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
14816 validity checking of assignments to elementary record components.
14817 (Expand_N_Return_Statement): return Class Wide types on the secondary
14818 stack independantly of their controlled status since with HIE runtimes,
14819 class wide types are not potentially controlled anymore.
14821 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
14824 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
14825 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
14826 it expects a block, procedure, or task. The return statement will get
14827 turned into a block, and Expand_Cleanup_Actions will happen then.
14829 2006-10-31 Robert Dewar <dewar@adacore.com>
14830 Ed Schonberg <schonberg@adacore.com>
14831 Bob Duff <duff@adacore.com>
14832 Gary Dismukes <dismukes@adacore.com>
14834 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
14836 (Expand_Inlined_Call): Tagged types are by-reference types, and
14837 therefore should be replaced by a renaming declaration in the expanded
14838 body, as is done for limited types.
14839 (Expand_Call): If this is a call to a function with dispatching access
14840 result, propagate tag from context.
14841 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
14843 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
14844 build-in-place when the right-hand side of an assignment is a
14845 build-in-place function call.
14846 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
14847 of the explicit dereference of the allocator to the result subtype of
14848 the build-in-place function. This is needed to satisfy type checking
14849 in cases where the caller's return object is created by an allocator for
14850 a class-wide access type and the type named in the allocator is a
14852 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
14853 conversion of the reference to the declared object to the result subtype
14854 of the build-in-place function. This is needed to satisfy type checking
14855 in cases where the declared object has a class-wide type. Also, in the
14856 class-wide case, change the type of the object entity to the specific
14857 result subtype of the function, to avoid passing a class-wide object
14858 without explicit initialization to the back end.
14859 (Register_Interface_DT_Entry): Moved outside the body of
14860 Freeze_Subprogram because this routine is now public; it is called from
14861 Check_Dispatching_Overriding to handle late overriding of abstract
14862 interface primitives.
14863 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
14864 adding an implicit access actual on a call to a build-in-place function.
14865 (Expand_Actuals): Test for an actual parameter that is a call to a
14866 build-in-place function and apply
14867 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
14868 (Is_Build_In_Place_Function): New function to determine whether an
14869 entity is a function whose calls should be handled as build-in-place.
14870 (Is_Build_In_Place_Function_Call): New function to determine whether an
14871 expression is a function call that should handled as build-in-place.
14872 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
14873 calls to build-in-place functions as the initialization of an allocator.
14874 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
14875 handling calls to build-in-place functions in contexts that do not
14876 involve init of a separate object (for example, actuals of subprogram
14878 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
14879 handling calls to build-in-place functions as the initialization of an
14880 object declaration.
14881 (Detect_Infinite_Recursion): Add explicit parameter Process to
14882 instantiation of Traverse_Body to avoid unreferenced warning.
14883 (Check_Overriding_Inherited_Interfaces): Removed.
14884 (Register_Interface_DT_Entry): Code cleanup.
14885 (Register_Predefined_DT_Entry): Code cleanup.
14886 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
14887 inlined statements if within a transient scope.
14888 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
14889 formal parameters with occurrences of actuals in inlined body, establish
14890 visibility on the proper view of the actual's subtype for the body's
14892 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
14893 compatibility mode and we have an imported CPP subprogram because
14894 for now we assume that imported CPP primitives correspond with
14895 objects whose constructor is in the CPP side (and therefore we
14896 don't need to generate code to register them in the dispatch table).
14897 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
14898 aligned selected component.
14899 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
14900 the actual of an in-mode parameter is a type conversion.
14901 (Expand_Actuals): If the call does not come from source and the actual
14902 is potentially misaligned, let gigi handle it rather than rejecting the
14903 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
14904 Class Wide types as returning by reference independantly of their
14905 controlled status since with HIE runtimes class wide types are not
14906 potentially controlled anymore.
14908 2006-10-31 Ed Schonberg <schonberg@adacore.com>
14910 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
14911 references that are private components of the protected object.
14912 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
14913 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
14914 instantiation to deal with warnings.
14915 (Initialize_Protection): If expression for priority is non-static, use
14916 System_Priority as its expected type, in case the expression has not
14919 2006-10-31 Robert Dewar <dewar@adacore.com>
14921 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
14922 initialization of Homonym_Len.
14923 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
14924 names from fully qualified name. Fixes problem of duplicate
14925 external names differing only in the presence of such a block name.
14927 2006-10-31 Thomas Quinot <quinot@adacore.com>
14928 Pablo Oliveira <oliveira@adacore.com>
14930 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
14931 subprogram Ids, even if they are not yet assigned.
14932 (Build_Subprogram_Id): It is now this function that will take care of
14933 calling Assign_Subprogram_Ids if necessary.
14934 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
14935 should be done only once they are assigned.
14936 (Build_From_Any_Function, case of tagged types): Add missing call to
14938 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
14939 type for an RACW type.
14940 (Add_RACW_Features): When processing an RACW declaration for which the
14941 designated type is already frozen, enforce E.2.2(14) rules immediately.
14942 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
14943 special reordering of controlling formals.
14945 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
14946 associated stub type for an RACW type.
14948 2006-10-31 Ed Schonberg <schonberg@adacore.com>
14950 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
14951 fixed-point operations in an integer context, i.e. as operands of a
14952 conversion to an integer type, indicate that result must be rounded.
14954 2006-10-31 Robert Dewar <dewar@adacore.com>
14956 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
14957 cases, pass the encoding method, since it is now required by the run
14960 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
14961 assumption that Str'First = 1.
14962 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
14963 it on to the Value_Wide_Wide_Character call.
14964 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
14965 properly handles a string of the form quote-encoded_wide_char-quote.
14967 * s-wchcnv.adb: Minor reformatting
14969 2006-10-31 Javier Miranda <miranda@adacore.com>
14971 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
14972 run-time membership test to ensure that the constructed object
14973 implements the target abstract interface.
14975 2006-10-31 Robert Dewar <dewar@adacore.com>
14977 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
14978 Machine_Attribute pragma internally to implement the user pragma.
14979 Add processing for pragma Interface so that it is now completely
14980 equivalent to pragma Import.
14982 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
14983 so that it can be applied to all entities, including record components
14984 and enumeration literals.
14985 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
14986 priority ranges are correct, verify compatibility against task
14987 dispatching and locking policies, and if everything is correct an entry
14988 is added to the table containing priority specific dispatching entries
14989 for this compilation unit.
14990 (Delay_Config_Pragma_Analyze): Delay processing
14991 Priority_Specific_Dispatching pragmas because when processing the
14992 pragma we need to access run-time data, such as the range of
14993 System.Any_Priority.
14994 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
14995 Allow pragma Unreferenced as a context item
14996 Add pragma Preelaborable_Initialization
14997 (Analyze_Pragma, case Interface): Interface is extended so that it is
14998 now syntactically and semantically equivalent to Import.
14999 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
15000 insertion characters.
15001 Add handling for Pragma_Wide_Character_Encoding
15002 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
15003 never supercedes a real restriction, and that a real restriction
15004 always supercedes a warning.
15005 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

15009 Ed Schonberg <schonberg@adacore.com>
15010 Robert Dewar <dewar@adacore.com>
15012 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
15013 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
15014 Is_Inherently_Limited_Type, because return-by-reference has no meaning
15016 (Find_Node_To_Be_Wrapped): Use new method of determining the result
15017 type of the function containing a return statement, because the
15018 Return_Type field was removed. We now use the Return_Applies_To field.
15020 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
15021 (Build_Task_Image_Decl): If procedure is not called from an
15022 initialization procedure, indicate that function that builds task name
15023 uses the sec. stack. Otherwise the enclosing initialization procedure
15024 will carry the indication.
15025 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
15026 N_Object_Declaration instead.
15027 (Kill_Dead_Code): New interface to implement -gnatwt warning for
15028 conditional dead code killed, and change implementation accordingly.
15029 (Insert_Actions): Add N_Return_Object_Declaration case.
15030 Correct comment to mention N_Extension_Aggregate node.
15031 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
15032 attempts to save information for global variables which cannot be
15034 (Get_Current_Value_Condition): Handle conditions the other way round
15035 (constant on left). Also handle right operand of AND and AND THEN
15036 (Set_Current_Value_Condition): Corresponding changes
15037 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
15038 (Get_Current_Value_Condition): Handle simple boolean operands
15039 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
15040 (Get_Current_Value_Condition): If the variable reference is within an
15041 if-statement, does not appear in the list of then_statments, and does
15042 not come from source, treat it as being at unknown location.
15043 (Get_Current_Value_Condition): Enhance to allow while statements to be
15044 processed as well as if statements.
15045 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
15047 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
15048 of loop. This is safe now that we fixed Kill_Current_Values.
15049 (OK_To_Do_Constant_Replacement): Check whether current scope is
15050 Standard, before examining outer scopes.
15052 2006-10-31 Vincent Celier <celier@adacore.com>
15054 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
15055 When True, apply VMS treatment to children of packages A, G, I and S.
15058 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
15060 2006-10-31 Robert Dewar <dewar@adacore.com>
15061 Ed Schonberg <schonberg@adacore.com>
15063 * freeze.adb: Add handling of Last_Assignment field
15064 (Warn_Overlay): Supply missing continuation marks in error msgs
15065 (Freeze_Entity): Add check for Preelaborable_Initialization
15067 * g-comlin.adb: Add Warnings (Off) to prevent new warning
15069 * g-expect.adb: Add Warnings (Off) to prevent new warning
15071 * lib-xref.adb: Add handling of Last_Assignment field
15072 (Generate_Reference): Centralize handling of pragma Obsolescent here
15073 (Generate_Reference): Accept an implicit reference generated for a
15074 default in an instance.
15075 (Generate_Reference): Accept a reference for a node that is not in the
15076 main unit, if it is the generic body corresponding to an subprogram
15079 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
15081 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
15083 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
15085 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
15086 use clauses, to avoid messages on packages used to qualify, and also
15087 to avoid messages from obsolescent units.
15088 (Warn_On_Useless_Assignments): Don't generate messages for imported
15089 and exported variables.
15090 (Warn_On_Useless_Assignments): New procedure
15091 (Output_Obsolescent_Entity_Warnings): New procedure
15092 (Check_Code_Statement): New procedure
15094 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
15095 Change name Is_Ada_2005 to Is_Ada_2005_Only
15096 (Last_Assignment): New field for useless assignment warning
15098 2006-10-31 Olivier Hainque <hainque@adacore.com>
15100 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
15101 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
15103 2006-10-31 Bob Duff <duff@adacore.com>
15104 Robert Dewar <dewar@adacore.com>
15105 Ed Schonberg <schonberg@adacore.com>
15107 * g-awk.adb (Default_Session, Current_Session): Compile this file in
15108 Ada 95 mode, because it violates the new rules for AI-318.
15110 * g-awk.ads: Use overloaded subprograms in every case where we used to
15111 have a default of Current_Session. This makes the code closer to be
15112 correct for both Ada 95 and 2005.
15114 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
15115 code, relying on the fact that the compiler generates a warning
15116 instead of an error in -gnatg mode.
15118 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
15119 E_Return_Statement entity kind.
15120 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
15122 * par.adb (P_Interface_Type_Definition): Addition of one formal to
15123 report an error if the reserved word abstract has been previously found.
15124 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
15126 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
15127 parenthesized range attribute usage
15128 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
15130 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
15131 in the syntax for extended_return_statement. This is not in the latest
15132 RM, but the ARG is expected to issue an AI allowing this.
15133 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
15134 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
15135 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
15136 P_Return_Statement): Parse the new syntax for extended_return_statement.
15138 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
15139 Output_End_Missing): Add error-recovery code for the new
15140 extended_return_statement syntax; that is, the new E_Return entry on
15143 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
15144 limited to nonlimited, because otherwise we violate the new Ada 2005
15145 rules about returning limited types in function Create_AST_Handler in
15148 * sem.adb (Analyze): Add cases for new node kinds
15149 N_Extended_Return_Statement and N_Return_Object_Declaration.
15151 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
15152 type is in the same category as type of context before applying check,
15153 to prevent anomalies in instantiations.
15154 (Resolve_Aggregate): Remove test for limited components in aggregates.
15155 It's unnecessary in Ada 95, because if it has limited components, then
15156 it must be limited. It's wrong in Ada 2005, because limited aggregates
15158 (Resolve_Record_Aggregate): Move check for limited types later, because
15159 OK_For_Limited_Init requires its argument to have been resolved.
15160 (Get_Value): When copying the component default expression for a
15161 defaulted association in an aggregate, use the sloc of the aggregate
15162 and not that of the original expression, to prevent spurious
15163 elaboration errors, when the expression includes function calls.
15164 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
15165 were missing. We also didn't handle qualified expressions. Now also
15166 allow function calls. Use new common routine OK_For_Limited_Init.
15167 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
15168 with space can upper case letter).
15170 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
15171 Has_Static_Discriminants flag
15172 (Record_Type_Declaration): Diagnose an attempt to declare an interface
15173 type with discriminants.
15174 (Process_Range_Expr_In_Decl): Do validity checks on range
15175 (Build_Discriminant_Constraints): Use updated form of
15176 Denotes_Discriminant.
15177 (Process_Subtype): If the subtype is a private subtype whose full view
15178 is a concurrent subtype, introduce an itype reference to prevent scope
15180 (Build_Derived_Record_Type, Collect_Interface_Primitives,
15181 Record_Type_Declaration): The functionality of the subprograms
15182 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
15183 is now performed by a single routine.
15184 (Build_Derived_Record_Type): If the type definition includes an explicit
15185 indication of limitedness, then the type must be marked as limited here
15186 to ensure that any access discriminants will not be treated as having
15187 a local anonymous access type.
15188 (Check_Abstract_Overriding): Issue a detailed error message when an
15189 abstract subprogram was not overridden due to incorrect mode of its
15191 (Analyze_Private_Extension_Declaration): Add support for the analysis of
15192 synchronized private extension declarations. Verify that the ancestor is
15193 a limited or synchronized interface or in the generic case, the ancestor
15194 is a tagged limited type or synchronized interface and all progenitors
15195 are either limited or synchronized interfaces.
15196 Derived_Type_Declaration): Check for presence of private extension when
15197 dealing with synchronized formal derived types.
15198 Process_Full_View): Enchance the check done on the usage of "limited" by
15199 testing whether the private view is synchronized.
15200 Verify that a synchronized private view is completed by a protected or
15202 (OK_For_Limited_Init_In_05): New function.
15203 (Analyze_Object_Declaration): Move check for limited types later,
15204 because OK_For_Limited_Init requires its argument to have been resolved.
15205 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
15206 in order to alleviate the upward compatibility introduced by AI-318.
15207 (Constrain_Corresponding_Record): If the constraint is for a component
15208 subtype, mark the itype as frozen, to avoid out-of-scope references to
15209 discriminants in the back-end.
15210 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
15211 this subprogram against wrong sources.
15212 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
15213 discriminant of limited type completed with a protected type, when the
15214 discriminant is used to constrain a private component of the type, and
15215 expansion is disabled.
15216 (Find_Type_Of_Object): Do not treat a return subtype that is an
15217 anonymous subtype as a local_anonymous_type, because its accessibility
15218 level is the return type of the enclosing function.
15219 (Check_Initialization): In -gnatg mode, turn the error "cannot
15220 initialize entities of limited type" into a warning.
15221 (OK_For_Limited_Init): Return true for generated nodes, since it
15222 sometimes violates the legality rules.
15223 (Make_Incomplete_Declaration): If the type for which an incomplete
15224 declaration is created happens to be the currently visible entity,
15225 preserve the homonym chain when removing it from visibility.
15226 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
15227 inherited subprograms.
15228 (Access_Definition): If this is an access to function that is the return
15229 type of an access_to_function definition, context is a type declaration
15230 and the scope of the anonymous type is the current one.
15231 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
15232 incomplete subtype to the set of private dependents of the original
15234 (Constrain_Discriminated_Type): Emit an error message whenever an
15235 incomplete subtype is being constrained.
15236 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
15237 corresponding subtype of the full view of the original incomplete type.

15252 Robert Dewar <dewar@adacore.com>
15254 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
15255 handling executable extension manually and duplicating code.
15257 * make.adb: Implement new -S switch
15258 (Gnatmake): Use new function Osint.Executable_Name instead
15259 of handling executable extension manually.
15261 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
15262 is specified, the executable name ends with this suffix.
15263 Take advantage of Osint.Executable_Name instead of duplicating code.

15267 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
15269 (Get_Target_Parameters): Set Executable_Extension_On_Target if

15274 2006-10-31 Vincent Celier <celier@adacore.com>
15276 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
15277 call it with -static-libgcc, as there are some platforms, such as
15278 Darwin, where one of these two switches is compulsory to link.
15280 2006-10-31 Vincent Celier <celier@adacore.com>
15282 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
15283 instead of ADA_PROJECT_PATH, for the project path.
15284 (Gnatls): When displaying the project path directories, use host dir
15287 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
15288 names in the project path, as absolute paths may correspond to
15289 multi-valued VMS logical names.
15291 2006-10-31 Vincent Celier <celier@adacore.com>
15293 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
15294 absolute path name.
15295 (Locate_Regular_File): Ditto
15296 (Change_Dir): Remove, no longer used

15320 2006-10-31 Robert Dewar <dewar@adacore.com>
15322 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
15324 (Layout_Variant_Record): Retrieve the discriminants from the entity
15325 rather than from the type definition, because in the case of a full
15326 type for a private type we need to take the discriminants from the
15328 (Layout_Component_List): When applying the Max operator to variants with
15329 a nonstatic size, check whether either operand is static and scale that
15330 operand from bits to storage units before applying Max.
15331 (Layout_Type): In VMS, if a C-convention access type has no explicit
15332 size clause (and does not inherit one in the case of a derived type),
15333 then the size is reset to 32 from 64.
15335 2006-10-31 Vincent Celier <celier@adacore.com>
15337 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
15338 its file has already been loaded, according to the unit being loaded,
15339 not to the current value of Multiple_Unit_Index.
15341 2006-10-31 Thomas Quinot <quinot@adacore.com>
15342 Eric Botcazou <ebotcazou@adacore.com>
15343 Arnaud Charlet <charlet@adacore.com>
15345 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
15346 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
15348 (a-except.o): Pass it to the compiler.
15349 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.

15369 * mlib-utl.adb (Initialized): Remove, no longer used
15370 (Initialize): Remove, no longer used
15371 (Ar): If Ar_Exec is null, get the location of the archive builder and,

15374 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
15377 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15379 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
15380 Process_Body_Clauses): If the context of a body includes a use clause
15381 for P.Q then a with_clause for P in the same body is not redundant,
15382 even if the spec also has a with_clause on P.
15383 Add missing continuation mark to error msg
15384 (Build_Limited_Views): A limited view of a type is tagged if its
15385 declaration includes a record extension.
15386 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
15387 node, even if the subunit has errors. This avoids malfunction by
15388 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
15389 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
15390 generation of obsolescent messages for with statements (cannot do
15391 this too early, or we cannot implement avoiding the messages in the
15392 case of obsolescent units withing obsolescent units).
15393 (Install_Siblings): If the with_clause is on a remote descendant of
15394 an ancestor of the current compilation unit, find whether there is
15395 a sibling child unit that is immediately visible.
15396 (Remove_Private_With_Clauses): New procedure, invoked after completing
15397 the analysis of the private part of a nested package, to remove from
15398 visibility the private with_clauses of the enclosing package
15400 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
15401 now centralized in Generate_Reference.
15402 (Install_Limited_Context_Clauses): Remove superfluous error
15403 message associated with unlimited view visible through use
15404 and renamings. In addition, at the point in which the error
15405 is reported, we add the backslash to the text of the error
15406 to ensure that it is reported as a single error message.
15407 Use new // insertion for some continuation messages
15408 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
15409 to create implicit with_clause for parent unit mentioned in original
15410 limited_with_clause.
15411 (Install_Limited_With_Unit): Set entity of parent identifiers if the
15412 unit is a child unit. For ASIS queries.
15413 (Analyze_Subunit): If the subunit appears within a child unit, make all
15414 ancestor child units directly visible again.

15429 a formal object declaration with an access definition or a subtype mark
15430 with a null exclusion.
15431 (P_Generic_Association): Handle association with box, and others_choice
15432 with box, to support Ada 2005 partially parametrized formal packages.
15434 2006-10-31 Robert Dewar <dewar@adacore.com>
15435 Javier Miranda <miranda@adacore.com>
15437 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
15438 (P_Type_Declaration): Remove barrier against the reserved word "limited"
15439 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
15440 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
15441 private extensions.
15442 (P_Type_Declaration): Add the new actual Abstract_Present to every call
15443 to P_Interface_Type_Definition.
15444 (P_Interface_Type_Definition): Addition of one formal to report an error
15445 if the reserved word abstract has been previously found.
15446 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
15447 object renaming declaration with an access definition or subtype mark
15448 with a possible null exclusion.

15464 2006-10-31 Vincent Celier <celier@adacore.com>
15466 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
15467 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
15470 2006-10-31 Vincent Celier <celier@adacore.com>
15472 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
15473 on VMS, change "__" to '.' before checking the name.
15474 (Record_Ada_Source): Always add the source file name in the list of
15475 of sources, even if it is not the first time, as it is for another
15477 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
15478 dot, instead of replacing only the first '_'.
15480 * prj-part.adb (Parse): Convert project file path to canonical form
15482 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
15483 extended, the project id of the project extending it is recorded in its
15484 data, even when it has already been processed as an imported project.
15486 2006-10-31 Robert Dewar <dewar@adacore.com>
15488 * repinfo.adb (List_Entities): Don't list entities from renaming
15491 2006-10-31 Arnaud Charlet <charlet@adacore.com>
15492 Robert Dewar <dewar@adacore.com>
15494 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
15495 only a restriction warning is active for the given restriction. This is
15496 desirable because we do not want to modify code in the case where only
15498 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
15499 causes overriding of real restrictions.
15500 Take advantage of new No_Restrictions constant.
15502 * raise.h: (__gnat_set_globals): Change profile.
15504 2006-10-31 Arnaud Charlet <charlet@adacore.com>
15506 * rtsfind.adb: Remove s-polint from comment as it exists no more.
15509 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
15510 Move all the entities in obsolete package System.PolyORB_Interface to
15511 System.Partition_Interface.
15512 (RE_Storage_Size): New function in System.Tasking.

15525 Thomas Quinot <quinot@adacore.com>
15526 Javier Miranda <miranda@adacore.com>
15527 Gary Dismukes <dismukes@adacore.com>
15529 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
15530 properly an attempt to apply Unchecked_Access to a protected operation.
15531 (OK_Self_Reference): New subprogram to check the legality of an access
15532 attribute whose prefix is the type of an enclosing aggregate.
15533 Generalizes previous mechanism to handle attribute references nested
15534 arbitrarily deep within the aggregate.
15535 (Analyze_Access_Attribute): An access attribute whose prefix is a type
15536 can appear in an aggregate if this is a default-initialized aggregate
15537 for a self-referential type.
15538 (Resolve_Attribute, case Access): Ditto.
15539 Add support for new implementation defined attribute Stub_Type.
15540 (Eval_Attribute, case Attribute_Stub_Type): New case.
15541 (Analyze_Attribute, case Attribute_Stub_Type): New case.
15542 (Stream_Attribute_Available): Implement using new subprogram from
15543 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
15544 Has_Specified_Stream_Attribute flag.
15545 Disallow Storage_Size and Storage_Pool for access to subprogram
15546 (Resolve_Attribute, case 'Access et al): Take into account anonymous
15547 access types of return subtypes in extended return statements. Remove
15548 accessibility checks on anonymous access types when Unchecked_Access is
15550 (Analyze_Attribute): Add support for the use of 'Class to convert
15551 a class-wide interface to a tagged type.
15552 Add support for the attribute Priority.
15553 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
15554 whether the designated type is discriminated with a constrained partial
15555 view and require static matching in that case.
15556 Add local variable Des_Btyp. The Designated_Type
15557 of an access to incomplete subtype is either its non-limited view if
15558 coming from a limited with or its etype if regular incomplete subtype.
15560 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
15561 Fix predicate to identify and allow cases of (expander-generated)
15562 references to tag of designated object of a RACW.
15563 (Validate_Static_Object_Name): In Ada 2005, a formal object is
15564 non-static, and therefore cannot appear as a primary in a preelaborable
15566 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
15567 Has_Read_Write_Attributes.
15568 (Has_Read_Write_Attributes): Reimplement in termes of
15569 Has_Stream_Attribute_Definition.
15570 (Missing_Read_Write_Attributes): When checking component types in a
15571 record, unconditionally call Missing_Read_Write_Attributes recursively
15572 (remove guard checking for Is_Record_Type / Is_Access_Type).
15574 2006-10-31 Robert Dewar <dewar@adacore.com>
15576 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
15577 useless assignments here and conditionalize it on absence of exception
15579 (Analyze_Exception_Handlers): Small code reorganization of error
15580 detection code, for new handling of formal packages.
15582 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15583 Hristian Kirtchev <kirtchev@adacore.com>
15585 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
15586 that has been constant-folded, preserve information of original tree,
15588 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
15589 generated private extension declaration if the formal derived type is
15590 synchronized. Carry synchronized present over to the generated private
15592 (Validate_Derived_Type_Instance): Ensure that the actual of a
15593 synchronized formal derived type is a synchronized tagged type.
15594 (Instantiate_Formal_Package): When creating the instantiation used to
15595 validate the actual package of a formal declared without a box, check
15596 whether the formal itself depends on a prior actual.
15597 (Instantiate_Formal_Subprogram): Create new entities for the defining
15598 identifiers of the formals in the renaming declaration, for ASIS use.
15599 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
15600 a renaming declaration or a subtype declaration for an actual in an
15601 instance, capture location information of declaration in generic, for
15603 (Instantiate_Formal_Package): Add comments on needed additional tests.
15604 AI-317 (partial parametrization) is fully implemented.
15605 (Validate_Private_Type_Instance): Add check for actual which
15606 must have preelaborable initialization
15607 Use new // insertion for some continuation messages
15608 (Analyze_Formal_Object_Declaration): Change usage of Expression to
15609 Default_Expression. Add type retrieval when the declaration has an
15610 access definition. Update premature usage of incomplete type check.
15611 (Check_Access_Definition): New subsidiary routine. Check whether the
15612 current compilation version is Ada 05 and the supplied node has an
15614 (Instantiate object): Alphabetize local variables. Handle the creation
15615 of new renaming declarations with respect to the kind of definition
15616 used - either an access definition or a subtype mark. Guard against
15617 unnecessary error message in the context of anonymous access types after
15618 they have been resolved. Add check for required null exclusion in a
15619 formal object declaration.
15620 (Switch_View): A private subtype of a non-private type needs to be
15621 switched (the base type can have been switched without its private
15622 dependents because of the last branch of Check_Private_View.
15623 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
15625 (Instantiate_Type): Emit an error message whenever a class-wide type of
15626 a tagged incomplete type is used as a generic actual.
15627 (Find_Actual_Type): Extend routine to handle a component type in a child
15628 unit that is imported from a formal package in a parent.
15629 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
15630 agree on constrainedness, rather than checking against ultimate ancestor
15631 (Instantiate_Subprogram_Body): Create a cross-reference link to the
15632 generic body, for navigation purposes.
15634 2006-10-31 Robert Dewar <dewar@adacore.com>
15635 Thomas Quinot <quinot@adacore.com>
15637 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
15639 (New_Stream_Subprogram): When processing an attribute definition clause
15640 for a stream-oriented subprogram, record an entity node occurring at
15641 the point of clause to use for checking the visibility of the clause,
15642 as defined by 8.3(23) as amended by AI-195.
15643 (New_Stream_Subprogram): New procedure, factoring behaviour from both
15644 New_Stream_Function and New_Stream_Procedure.
15645 (New_Stream_Function, New_Stream_Procedure): Removed.
15646 (Analyze_Attribute_Definition_Clause, case Address): Check new
15647 Alignment_Check check
15649 2006-10-31 Ed Schonberg <schonberg@adacore.com>
15650 Javier Miranda <miranda@adacore.com>
15651 Robert Dewar <dewar@adacore.com>
15653 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
15654 generate the same errors compiling under -gnatc.
15655 (Try_Object_Operation): If no candidate interpretation succeeds, but
15656 there is at least one primitive operation with the right name, report
15657 error in call rather than on a malformed selected component.
15658 (Analyze_Selected_Component): If the prefix is an incomplete type from
15659 a limited view, and the full view is available, use the full view to
15660 determine whether this is a prefixed call to a primitive operation.
15661 (Operator_Check): Verify that a candidate interpretation is a binary
15662 operation before checking the type of its second formal.
15663 (Analyze_Call): Add additional warnings for function call contexts not
15665 (Analyze_Allocator): Move the check for "initialization not allowed for
15666 limited types" after analyzing the expression. This is necessary,
15667 because OK_For_Limited_Init looks at the structure of the expression.
15668 Before analysis, we don't necessarily know what sort of expression it
15669 is. For example, we don't know whether F(X) is a function call or an
15670 indexed component; the former is legal in Ada 2005; the latter is not.
15671 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
15672 were missing. We also didn't handle qualified expressions. Now also
15673 allow function calls. Use new common routine OK_For_Limited_Init.
15674 (Analyze_Type_Conversion): Do not perform some legality checks in an
15675 instance, because the error message will be redundant or spurious.
15676 (Analyze_Overloaded_Selected_Component): Do not do style check when
15677 setting an entity, since we do not know it is the right entity yet.
15678 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
15679 (Analyze_Overloaded_Selected_Component): Same change
15680 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
15681 since regular incomplete subtypes are transformed into corresponding
15682 subtypes of their full views.
15683 (Complete_Object_Operation): Treat name of transformed subprogram call
15684 as coming from source, for browsing purposes.
15685 (Try_Primitive_Operation): If formal is an access parameter, compare
15686 with base type of object to determine whether it is a primitive
15688 (Operator_Check): If no interpretation of the operator matches, check

15700 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
15701 (Process_Bounds): If the bounds are integer literals that result from
15702 constant-folding, and they carry a user-defined type, preserve that type
15703 rather than treating this as an integer range.
15704 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
15705 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
15706 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
15707 left hand side of assignment.

15713 or AND THEN for possible tracking.
15714 (Analyze_Iteration_Scheme): Check for setting Current_Value for the

15719 Bob Duff <duff@adacore.com>
15721 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
15722 procedure cannot be a protected operation (it is a basic_declaration,
15723 not a subprogram_declaration).
15724 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
15725 Subp. Add logic for entry processing.
15726 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.

15740 pass new parameters. Add support for adding the new extra access formal
15741 for functions whose calls are treated as build-in-place.
15742 (Analyze_A_Return_Statement): Correct casing in error message.
15743 Move Pop_Scope to after Analyze_Function_Return, because an extended
15744 return statement really is a full-fledged scope. Otherwise, visibility
15745 doesn't work right. Correct use of "\" for continuation messages.
15746 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
15747 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
15748 the node doesn't get properly marked as analyzed.
15749 (Analyze_Subprogram_Body): If subprogram is a function that returns
15750 an anonymous access type that denotes a task, build a Master Entity
15752 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
15753 proper usage of null exclusion in a result definition.

15767 (Analyze_Subprogram_Declaration): Check that abstract interface
15768 primitives are abstract or null.
15769 (Analyze_Subprogram_Specification): Remove previous check for abstract
15770 interfaces because it was not complete.
15771 (Has_Interface_Formals): Removed.

15776 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
15777 of Analyze_Package_Body, to create Itype references for anonymous
15778 access types created in the package declaration, whose designated types
15779 may have only a limited view.
15780 (Analyze_Package_Specification): For the private part of a nested
15781 package, install private_with_clauses of enclosing compilation unit if
15782 we are in its visible part.
15783 (Declare_Inherited_Private_Subprograms): Complete barrier
15784 to ensure that the primitive operation has an alias to some parent
15785 primitive. This is now required because, after the changes done for the
15786 implementation of abstract interfaces, the contents of the list of
15787 primitives has entities whose alias attribute references entities of
15788 such list of primitives.
15789 (Analyze_Package_Specification): Simplify code that handles parent units
15790 of instances and formal packages.
15791 (Uninstall_Declarations): Check the convention consistency among
15792 primitive overriding operations of a tagged record type.

15806 as potentially use-visible.
15807 (Find_Type): Handle the case of an attribute reference for
15808 implementation defined attribute Stub_Type (simply let the analysis of
15809 the attribute reference rewrite it).

15811 type that appears in a Use_Type clause.
15812 (Analyze_Object_Renaming): Add support for renaming of the Priority

15817 (Analyze_Object_Renaming): Introduce checks for required null exclusion
15818 in a formal object declaration or in a subtype declaration.
15819 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
15820 (Check_Null_Exclusion): New local routine to
15821 Analyze_Subprogram_Renaming. Check whether the formals and return
15822 profile of a renamed subprogram have required null exclusions when
15823 their counterparts of the renaming already impose them.
15824 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
15825 Determine whether an entity is inside a generic scope.
15826 (In_Open_Scope): First pass of documentation update.
15827 (Find_Expanded_Name): Add support for shadow entities associated with
15828 limited withed packages. This is required to handle nested packages.
15829 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
15830 that makes a renaming of a limited withed package illegal.

15833 Ed Schonberg <schonberg@adacore.com>
15835 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
15836 Check_Overriding_Indicator.
15837 (Analyze_Task_Definition): Ditto.
15838 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
15839 (Check_Overriding_Indicator): To find overridden interface operation,
15840 examine only homonyms that have an explicit subprogram declaration, not
15841 inherited operations created by an unrelated type derivation.
15842 (Check_Overriding_Indicator): When checking for the presence of "null"
15843 in a procedure, ensure that the queried node is a procedure

15846 type when the formal is an access to variable.
15847 (Analyze_Protected_Type): Add check for Preelaborable_Initialization

15861 of a call to a function that dispatches on access result.
15862 (Check_Dispatching_Operation): In case of late overriding of a primitive

15864 secondary dispatch tables associated with abstract interfaces.
15865 (Check_Dispatching_Call): Add check that a dispatching call is not made
15866 to a function with a controlling result of a limited type. This is a
15867 current implementation restriction.
15868 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
15869 (Check_Dispatching_Operation): Do no emit a warning if the controlling
15870 argument is an interface type that is a generic formal.
15871 (Is_Interface_Subprogram): Removed.
15872 (Check_Dispatching_Operation): If the subprogram is not a dispatching
15873 operation, check the formals to handle the case in which it is
15874 associated with an abstract interface type.

15897 the context of generic instantiation.
15898 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
15899 abstract interface types; this is required to handle concurrent types

15916 qualification from an expression. There are numerous places where this
15917 ought to be used, but we currently only deal properly with zero or one
15919 (In_Instance); The analysis of the actuals in the instantiation of a
15920 child unit is not within an instantiation, even though the parent
15921 instance is on the scope stack.

15924 (Check_Obsolescent): Removed
15925 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

16003 (N_Extended_Return_Statement): New node for extended_return_statement
16005 (N_Return_Object_Declaration): New node for part of

16180 This is a significant redesign primarily for the sake of automatic
16181 timer task termination but also to fix a design flaw.
16182 Therefore we are now using an RTS lock, instead of a protected
16183 object, to provide mutual exclusion to the queue of pending events
16184 and the type Timing_Event is no longer a protected type.

16690 we must pass the work to the expander to generate the required code to
16691 evaluate the conversion at run-time.
16692 (Resolve_Equality_Op): Do not apply previous

17366 save/restore routines.
17367 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

17369 Since we are changing the tree format anyway, also get rid of the
17370 junk obsolete Immediate_Errors flag.
17371 (Tree_Read): Change the way of reading Tree_Version_String - now we

17462 (Freeze_Record_Type): Do not generate the tables associated with
17463 timed and conditional dispatching calls through synchronized
17464 interfaces if compiling under No_Dispatching_Calls restriction.
17465 When compiling for Ada 2005, for a nonabstract
17466 type with a null extension, call Make_Controlling_Function_Wrappers
17467 and insert the wrapper function declarations and bodies (the latter
17468 being appended as freeze actions).
17469 (Predefined_Primitive_Bodies): Do not generate the bodies of the
17470 predefined primitives associated with timed and conditional
17471 dispatching calls through synchronized interfaces if we are
17472 compiling under No_Dispatching_Calls.
17473 (Build_Init_Procedure): Use RTE_Available to check if a run-time
17474 service is available before generating a call.
17475 (Make_Controlling_Function_Wrappers): New procedure.
17476 (Expand_N_Full_Type_Declaration): Create a class-wide master for
17477 access-to-limited-interfaces because they can be used to reference
17478 tasks that implement such limited interface.
17479 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
17480 procedure spec and body of the Offset_To_Top function that is generated
17481 when the parent of a type with discriminants has secondary dispatch
17483 (Init_Secondary_Tags): Handle the case in which the parent of the type
17484 containing secondary dispatch tables has discriminants to generate the
17485 correct arguments to call Set_Offset_To_Top.
17486 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
17488 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
17489 Add Wide_[Wide_]Expanded_Name.
17490 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
17491 the same functionality of Get_Prim_Op_Address but applied to predefined
17492 primitive operations because the pointers to the predefined primitives
17493 are now saved in a separate table.
17494 (Parent_Size): Modified to get access to the separate table of primitive
17495 operations or the parent type.
17496 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
17497 functionality of Set_Prim_Op_Address but applied to predefined primitive
17499 (Set_Signature): New subprogram used to store the signature of a DT.
17500 (Displace): If the Offset_To_Top value is not static then call the
17501 function generated by the expander to get such value; otherwise use
17502 the value stored in the table of interfaces.
17503 (Offset_To_Top): The type of the actual has been changed to Address to
17504 give the correct support to tagged types with discriminants. In this
17505 case this value is stored just immediately after the tag field.
17506 (Set_Offset_To_Top): Two new formals have been added to indicate if the
17507 offset_to_top value is static and hence pass this value to the run-time
17508 to store it in the table of interfaces, or else if this value is dynamic
17509 and then pass to the run-time the address of a function that is
17510 generated by the expander to provide this value for each object of the
17513 * rtsfind.ads (Default_Prin_Op_Count): Removed.
17514 (Default_Prim_Op_Count): New entity

17523 Make_Adjust_Call done for a newly-allocated object.
17525 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
17526 in a subprogram are wrapped in a cleanup block, indicate that the
17527 subprogram contains an inner block with an exception handler.
17528 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
17529 Adjust call is for a newly-allocated object. In that case we must not
17530 assume that the finalization list chain pointers are correct (since they
17531 come from a bit-for-bit copy of the original object's pointers) so if
17532 the attach level would otherwise be zero (no change), we set it to 4
17533 instead to cause the pointers to be reset to null.
17535 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
17536 reset chain pointers to null.
17538 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17540 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
17541 string, and the context requires a loop for the assignment (e.g.
17542 because the left-hand side is packed), generate a unique name for the
17543 temporary that holds the string, to prevent spurious name clashes.

17548 Gary Dismukes <dismukes@adacore.com>
17550 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
17551 return unconstrained arrays.
17553 (Expand_Call): An indirect call through an access parameter of a
17554 protected operation is not a protected call.
17555 Add circuit to raise CE in Ada 2005 mode following call
17556 to Raise_Exception.
17557 (Register_DT_Entry): Do nothing if
17558 the run-time does not give support to abstract interfaces.
17559 (Freeze_Subprogram): In case of dispatching operations, do not generate
17560 code to register the operation in the dispatch table if the source
17561 is compiled with No_Dispatching_Calls.
17562 (Register_Predefined_DT_Entry): Generate code that calls the new
17563 run-time subprogram Set_Predefined_Prim_Op_Address instead of
17564 Set_Prim_Op_Address.
17566 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
17567 on array assignments if the right-hand side is a function call that has
17568 been inlined. Check is performed on the assignment in the block.
17569 (Process_Bounds): If bounds and range are overloaded, apply preference
17570 rule for root operations to disambiguate, and diagnose true ambiguity.
17571 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
17572 a tag-indeterminate right-hand side even when Expander_Active is True.
17573 Needed to ensure that dispatching calls to T'Input are allowed and
17574 get the tag of the target class-wide object.
17576 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
17577 an inherited primitive operation that already overrides several
17578 abstract interface primitives. For transitivity, the new entity must
17579 also override all the abstract interface primitives covered by the
17580 inherited overriden primitive.
17581 Emit warning if new entity differs from homograph in same scope only in
17582 that one has an access parameter and the other one has a parameter of
17583 a general access type with the same designated type, at the same
17584 position in the signature.
17585 (Make_Inequality_Operator): Use source locations of parameters and
17586 subtype marks from corresponding equality operator when creating the
17587 tree structure for the implicit declaration of "/=". This does not
17588 change anything in behaviour except that the decoration of the
17589 components of the subtree created for "/=" allows ASIS to get the
17590 string images of the corresponding identifiers.
17591 (Analyze_Return_Statement): Remove '!' in warning message.
17592 (Check_Statement_Sequence): Likewise.
17593 (Analyze_Subprogram_Body): For an access parameter whose designated type
17594 is an incomplete type imported through a limited_with clause, use the
17595 type of the corresponding formal in the body.
17596 (Check_Returns): Implicit return in No_Return procedure now raises
17597 Program_Error with a compile time warning, instead of beging illegal.
17598 (Has_Single_Return): Function returning unconstrained type cannot be
17599 inlined if expression in unique return statement is not an identifier.
17600 (Build_Body_To_Inline): It is possible to inline a function call that
17601 returns an unconstrained type if all return statements in the function
17602 return the same local variable. Subsidiary procedure Has_Single_Return
17603 verifies that the body conforms to this restriction.
17605 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
17606 same type, and one of them is of an anonymous access type, convert
17607 the other operand to it, so that this is a valid binary operation for
17609 (Resolve_Type_Conversion): Handle subtypes of protected types and
17610 task types when accessing to the corresponding record type.
17611 (Resolve_Allocator): Add '\' in 2-line warning message.
17612 Remove '!' in warning message.
17613 (Resolve_Call): Add '\' in 2-line warning message.
17614 (Valid_Conversion): Likewise.
17615 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
17616 resulting type may be an access type with an implicit dereference.
17617 Obtain the proper component from the designated type.
17618 (Make_Call_Into_Operator): Handle properly a call to predefined equality
17619 given by an expanded name with prefix Standard, when the operands are
17620 of an anonymous access type.
17621 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
17622 Explicit_Dereference and Resolve_Selected_Component, to verify that the
17623 prefix of the expression is not of an incomplete type. Allows full
17624 diagnoses of all semantic errors.
17625 (Resolve_Actuals): If the actual is an allocator whose directly
17626 designated type is a class-wide interface we build an anonymous
17627 access type to use it as the type of the allocator. Later, when
17628 the subprogram call is expanded, if the interface has a secondary
17629 dispatch table the expander will add a type conversion to force
17630 the displacement of the pointer.
17631 (Resolve_Call): If a function that returns an unconstrained type is
17632 marked Inlined_Always and inlined, the call will be inlined and does
17633 not require the creation of a transient scope.
17634 (Check_Direct_Boolean_Op): Removed
17635 (Resolve_Comparison_Op): Remove call to above
17636 (Resolve_Equality_Op): Remove call to above
17637 (Resolve_Logical_Op): Inline above, since this is only call.
17638 (Valid_Conversion): Handle properly conversions between arrays of
17639 convertible anonymous access types.
17642 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
17643 the literal in an unchecked conversion, because GCC 4.x needs a static
17644 value for a string bound.
17646 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17647 Hristian Kirtchev <kirtchev@adacore.com>
17649 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
17650 components of the corresponding record, take into account component
17651 definitions that are access definitions.
17652 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
17653 procedure is not considered a dispatching call and will be expanded
17656 2006-02-13 Javier Miranda <miranda@adacore.com>
17658 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
17659 controlling argument of the dispatching call is an abstract interface
17660 class-wide type then we use it directly.
17661 Check No_Dispatching_Calls restriction.
17662 (Default_Prim_Op_Position): Remove the code that looks for the last
17663 entity in the list of aliased subprograms. This code was wrong in
17665 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
17666 when the source is compiled with the No_Dispatching_Calls restriction.
17667 (Init_Predefined_Interface_Primitives): No need to inherit primitives
17668 if we are compiling with restriction No_Dispatching_Calls.
17669 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
17670 subprograms if we are compiling under No_Dispatching_Calls restriction.
17671 (Make_DT): Generate a dispatch table with a single dummy entry if
17672 we are compiling with the No_Dispatching_Calls restriction. In
17673 addition, in this case we don't generate code that calls to the
17674 following run-time subprograms: Set_Type_Kind, Inherit_DT.
17675 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
17676 of this subprogram if compiling with the No_Dispatching_Calls
17678 (Expand_Type_Conversion): Instead of using the actual parameter,
17679 the argument passed as parameter to the conversion function was
17680 erroneously referenced by the expander.
17681 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
17682 Set_Predefined_Primitive_Op_Address and Set_Signature.
17683 (Expand_Dispatching_Call): Generate call to
17684 Get_Predefined_Prim_Op_Address for predefined primitives.
17685 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
17686 predefined primitives.
17687 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
17688 primitives we reserve one dummy entry to ensure that the tag does not
17689 point to some memory that is associated with some other object. In
17690 addition, remove all the old code that generated the assignments
17691 associated with the signature of the dispatch table and replace them
17692 by a call to the new subprogram Set_Signature.
17693 (Set_All_DT_Position): Change the algorithm because now we have a
17694 separate dispatch table associated with predefined primitive operations.
17695 (Expand_Interface_Conversion): In case of non-static offset_to_top
17696 add explicit dereference to get access to the object after the call
17697 to displace the pointer to the object.
17698 (Expand_Interface_Thunk): Modify the generation of the actual used
17699 in the calls to the run-time function Offset_To_Top to fulfil its
17701 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
17703 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17705 * exp_dist.adb (Copy_Specification): For access parameters, copy
17706 Null_Exclusion flag, which will have been set for stream subprograms
17709 2006-02-13 Pascal Obry <obry@adacore.com>
17711 * expect.c (__gnat_expect_portable_execvp): New implementation. The
17712 previous implementation was using the C runtime spawnve routine but
17713 the corresponding wait was using directly the Win32 API. This was
17714 causing some times a lock when waiting for an event using
17715 WaitForSingleObject in __gnat_waitpid. This new implementation uses
17716 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
17717 API fixes this problem.
17719 2006-02-13 Robert Dewar <dewar@adacore.com>
17721 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

17729 array reference that is an explicit dereference, mark the converted
17730 (packed) array reference as analyzed to prevent a forthcoming
17731 reanalysis from resetting its type to the original (non-packed) array
17734 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17735 Javier Miranda <miranda@adacore.com>
17736 Eric Botcazou <ebotcazou@adacore.com>
17738 * exp_util.ads, exp_util.adb (Find_Prim_Op,
17739 Is_Predefined_Primitive_Operation): When
17740 searching for the predefined equality operator, verify that operands
17741 have the same type.
17742 (Is_Predefined_Dispatching_Operation): Remove the code that looks
17743 for the last entity in the list of aliased subprograms. This code
17744 was wrong in case of renamings.
17745 (Set_Renamed_Subprogram): New procedure
17746 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
17747 Exp_Type constant computed when entering this subprogram.

17749 (OK_To_Do_Constant_Replacement): New function
17750 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
17751 (Side_Effect_Free): An attribute reference 'Input is not free of
17752 side effect, unlike other attributes that are functions. (from code
17754 (Remove_Side_Effects): Expressions that involve packed arrays or records
17755 are copied at the point of reference, and therefore must be marked as
17756 renamings of objects.
17757 (Is_Predefined_Dispatching_Operation): Return false if the operation is
17758 not a dispatching operation.
17761 (Remove_Side_Effects): Lift enclosing type conversion nodes for
17762 elementary types in all cases.
17764 2006-02-13 Javier Miranda <miranda@adacore.com>
17766 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
17767 task types when accessing to the corresponding record type.
17768 Remove '!' in warning message.
17770 2006-02-13 Olivier Hainque <hainque@adacore.com>
17772 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
17773 to avoid useless and space inefficient overalignments on targets where
17774 Max_Alignment is larger than 16.
17776 2006-02-13 Pascal Obry <obry@adacore.com>
17778 * g-catiio.adb (Sec_Number): New type used to compute the number of
17779 seconds since 1-1-1970.
17780 (Image) [Natural]: The parameter was an Integer, as we can't deal with
17781 negative numbers (years, months...) it is better to have a Natural here.
17783 (Image) [Number]: Change parameter from Long_Integer to Number.
17784 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
17785 overflow for dates past year 2038.
17787 2006-02-13 Matthew Heaney <heaney@adacore.com>
17789 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
17792 2006-02-13 Arnaud Charlet <charlet@adacore.com>
17794 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
17796 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
17797 finalization can occur normally.
17799 2006-02-13 Vincent Celier <celier@adacore.com>
17801 * gnatcmd.adb (Rules_Switches): New table
17802 (Add_To_Rules_Switches): New procedure
17803 (GNATCmd): For command CHECK, put all options following "-rules" in the
17804 Rules_Switches table. Append these -rules switches after the -cargs
17807 2006-02-13 Robert Dewar <dewar@adacore.com>
17809 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
17810 These two cases were generating incorrect output, and if this unit
17811 was built with checks on, generated a discriminant mismatch constraint
17814 2006-02-13 Ed Schonberg <schonberg@adacore.com>
17815 Robert Dewar <dewar@adacore.com>
17817 * lib-xref.adb (Get_Type_Reference): For a private type whose full
17818 view is an array type, indicate the component type as well, for
17819 navigation purposes.
17820 (Generate_Reference): Don't consider array ref on LHS to be a case
17821 of violating pragma Unreferenced.
17822 Do not give Ada 2005 warning except on real reference.
17824 2006-02-13 Vincent Celier <celier@adacore.com>
17826 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
17827 main source, add switch -mdebug-main=_ada_ so that the executable can
17828 be debugged by the standard VMS debugger.
17829 (Gnatmake): Set No_Main_Subprogram to True when there is no main
17830 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
17831 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
17832 of the last source, as the binding and linking phases are never
17834 Set all executable obsolete when rebuilding a library.
17836 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
17839 2006-02-13 Javier Miranda <miranda@adacore.com>
17842 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
17843 code to improve the error message reported when the program has
17844 declarations of abstract interface types and it is not compiled with
17845 the -gnat05 switch.
17846 (P_Access_Definition): Reorganize the code to improve the error
17847 message reported when the new Ada 2005 syntax for anonymous
17848 access types is used and the program is not compiled with the

17871 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
17872 unknown, use the location of the project to report the error.
17873 (When_No_Sources): New global variable
17874 (Report_No_Ada_Sources): New procedure
17875 (Check): New parameter When_No_Sources. Set value of global variable

17886 Call Recursive_Check with parameter When_No_Sources.
17887 (Recursive_Check): New parameter When_No_Sources. Call itself and
17888 Prj.Nmsc.Check with parameter When_No_Sources.
17889 (Process): New parameter When_No_Sources. Call Check with parameter
17891 (Copy_Package_Declarations): New procedure to copy renamed parameters
17892 and setting the location of the declared attributes to the location
17893 of the renamed package.
17894 (Process_Declarative_Items): Call Copy_Package_Declarations for renamed
17897 2006-02-13 Vincent Celier <celier@adacore.com>
17899 * prj-makr.adb (Make): Preserve the comments from the original project
17901 When removing nodes (attributes Source_Dirs, Source_Files,
17902 Source_List_File and package Naming), save the comments and attach the
17903 saved comments to the newly created nodes.
17904 Do not add a with clause for the naming package if one already exists.

17916 (Check_Dispatching_Operation): Do not generate code to register the
17917 operation in the dispatch table if the source is compiled with
17918 restriction No_Dispatching_Calls.

17920 No_Return procedure with procedure that is not No_Return
17921 (Check_Dispatching_Call): Suppress the check for an abstract operation
17922 when the original node of an actual is a tag-indeterminate attribute
17923 call, since the attribute, which must be 'Input, can never be abstract.
17924 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
17925 call to the Input attribute (even when rewritten).
17926 (Propagate_Tag): Augment comment to indicate the possibility of a call
17927 to an Input attribute.
17929 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
17930 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
17932 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
17933 No_Wide_Characters is no longer partition-wide
17934 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
17937 2006-02-13 Douglas Rupp <rupp@adacore.com>
17939 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
17941 2006-02-13 Javier Miranda <miranda@adacore.com>
17943 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
17944 handles default-initialized components to keep separate the management
17945 of this feature but also avoid the unrequired resolution and
17946 expansion of components that do not have partially initialized
17948 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
17949 (Check_Bounds): Likewise.
17950 (Check_Length): Likewise.
17952 2006-02-13 Javier Miranda <miranda@adacore.com>
17953 Ed Schonberg <schonberg@adacore.com>
17955 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
17956 abstract interface type call analyze_and_resolve to expand the type
17957 conversion into the corresponding displacement of the
17958 reference to the base of the object.
17959 (Eval_Attribute, case Width): For systems where IEEE extended precision
17960 is supported, the maximum exponent occupies 4 decimal digits.
17961 (Accessibility_Message): Add '\' in 2-line warning message.
17962 (Resolve_Attribute): Likewise.
17963 (case Attribute_Access): Significantly revise checks
17964 for illegal access-to-subprogram Access attributes to properly enforce
17965 the rules of 3.10.2(32/2).
17966 Diagnose use of current instance with an illegal attribute.
17968 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
17970 (Enclosing_Generic_Unit): New function to return a node's innermost
17971 enclosing generic declaration node.
17972 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
17973 (Type_Access_Level): The accessibility level of anonymous acccess types
17974 associated with discriminants is that of the current instance of the
17975 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
17976 (Compile_Time_Constraint_Error): Handle case of conditional expression.
17977 (Kill_Current_Values_For_Entity): New function
17978 (Enter_Name): Change formal type to Entity_Id
17980 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
17981 Ed Schonberg <schonberg@adacore.com>
17982 Gary Dismukes <dismukes@adacore.com>
17984 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
17985 Analyze_Compilation_Unit.
17986 Detect and warn on redundant with clauses detected in a package spec
17987 and/or body when -gnatwr is used.
17988 (Analyze_Context): Analyze config pragmas before other items
17989 (Install_Context_Items): Don't analyze config pragmas here
17990 (Install_Limited_Withed_Unit): Set limited entity of package in
17991 with_clause so that cross-reference information or warning messages on
17992 unused packages can be properly generated
17993 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
17994 has Error_Posted set. Prevent infinite loops in illegal programs.
17995 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
17996 to the point of the error test requiring the current unit to be private.
17997 This ensures that private with clauses are not exempted from the basic
17998 checking for being a descendant of the same library unit parent as a
17999 withed private descendant unit.
18000 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
18001 handle private with clauses properly, as well as to account for cases
18002 where the withed unit is a public descendant of a private ancestor
18003 (in which case the current unit must be a descendant of the private
18004 ancestor's parent). The spec comments were updated accordingly. Also,
18005 the old error message in this subprogram was replaced with error
18006 messages that mirror the errors tested and reported by
18007 Check_Private_Child_Unit.
18008 Parameter and variable names improved for readability.
18009 (Install_Limited_Context_Clauses): Remove test for a withed unit being
18010 private as the precondition for calling
18011 Check_Private_Limited_Withed_Unit since that subprogram has been
18012 revised to test public units as well as private units.

18019 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
18020 that Scope_Stack.First = 1.
18021 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18022 were not always properly handled previously.
18023 (Formal_Entity): Complete rewrite, to handle properly some complex case
18024 with multiple levels of parametrization by formal packages.
18025 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
18026 to the corresponding derived type declaration for proper semantics.
18028 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
18029 (Check_Component): Enforce restriction on components of
18030 unchecked_unions: a component in a variant cannot contain tasks or
18032 (Unchecked_Union): Allow nested variants and multiple discriminants, to
18034 Add pragma Ada_2005 (synonym for Ada_05)
18035 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
18036 were not always properly handled previously.
18037 Document that pragma Propagate_Exceptions has no effect
18038 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
18039 (Set_Convention_From_Pragma): Check that if a convention is
18040 specified for a dispatching operation, then it must be
18041 consistent with the existing convention for the operation.
18042 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
18043 longer required to specify an vtable-ptr component in the record. For
18044 compatibility reasons we leave the support for the previous definition.
18045 (Analyze_Pragma, case No_Return): Allow multiple arguments
18047 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
18048 non-overrideen inherited operation with a controlling result as
18049 illegal only its implicit declaration comes from the derived type
18050 declaration of its result's type.
18051 (Check_Possible_Deferred_Completion): Relocate the object definition
18052 node of the subtype indication of a deferred constant completion rather
18053 than directly analyzing it. The analysis of the generated subtype will
18054 correctly decorate the GNAT tree.
18055 (Record_Type_Declaration): Check whether this is a declaration for a
18056 limited derived record before analyzing components.
18057 (Analyze_Component_Declaration): Diagnose record types not explicitly
18058 declared limited when a component has a limited type.
18059 (Build_Derived_Record_Type): Code reorganization to check if some of
18060 the inherited subprograms of a tagged type cover interface primitives.
18061 This check was missing in case of a full-type associated with a private
18063 (Constant_Redeclaration): Check that the subtypes of the partial and the
18064 full view of a constrained deferred constant statically match.
18065 (Mentions_T): A reference to the current type in an anonymous access
18066 component declaration must be an entity name.
18067 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
18068 class_wide type to refer to full type, not to the incomplete one.
18069 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
18070 available. Required to give support to the certified run-time.
18071 (Analyze_Component_Declaration): In case of anonymous access components
18072 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
18073 (Process_Discriminants): For an access discriminant, use the
18074 discriminant specification as the associated_node_for_itype, to
18075 simplify accessibility checks.

18080 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
18081 abstract interpretations on an operator, remove interpretations that
18082 yield Address or a type derived from it, if one of the operands is an
18084 (Try_Object_Operation.Try_Primitive_Operation,
18085 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
18086 location when creating the new reference to a primitive or class-wide
18087 operation as a part of rewriting a subprogram call.
18088 (Try_Primitive_Operations): If context requires a function, collect all
18089 interpretations after the first match, because there may be primitive
18090 operations of the same type with the same profile and different return
18091 types. From code reading.
18092 (Try_Primitive_Operation): Use the node kind to choose the proper
18093 operation when a function and a procedure have the same parameter
18095 (Complete_Object_Operation): If formal is an access parameter and prefix
18096 is an object, rewrite as an Access reference, to match signature of
18097 primitive operation.
18098 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
18099 by an expanded name with prefix Standard, when the operands are of an
18100 anonymous access type.
18101 (Remove_Abstract_Operations): If the operation is abstract because it is
18102 inherited by a user-defined type derived from Address, remove it as
18103 well from the set of candidate interpretations of an overloaded node.
18104 (Analyze_Membership_Op): Membership test not applicable to cpp-class
18107 2006-02-13 Bob Duff <duff@adacore.com>
18109 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
18110 redundant use clauses.
18111 In particular, if the scope of two use clauses overlaps, but one is not
18112 entirely included in the other, we should not warn. This can happen
18113 with nested packages.
18114 (Analyze_Subprogram_Renaming): Protect the compiler against previously
18115 reported errors. The bug was reported when the compiler was built
18116 with assertions enabled.
18117 (Find_Type): If the node is a 'Class reference and the prefix is a
18118 synchronized type without a corresponding record, return the type
18121 2006-02-13 Javier Miranda <miranda@adacore.com>
18123 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
18124 if this is the full-declaration associated with a private declaration
18125 that implement interfaces, then the private type declaration must be
18127 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
18128 as aliased. The use of the 'access attribute is not available for such
18129 object (for this purpose the object should be explicitly marked as
18130 aliased, but being an anonymous type this is not possible).
18132 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18133 Robert Dewar <dewar@adacore.com>
18135 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
18136 compilation unit is an elaboration scope.
18137 (Add_Task_Proc): Add '\' in 2-line warning message.
18138 (Activate_All_Desirable): Deal with case of unit with'ed by parent
18140 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18141 Javier Miranda <miranda@adacore.com>
18143 * sem_type.adb (Write_Overloads): Improve display of candidate
18145 (Add_One_Interp): Do not add to the list of interpretations aliased
18146 entities corresponding with an abstract interface type that is an
18147 immediate ancestor of a tagged type; otherwise we have a dummy
18148 conflict between this entity and the aliased entity.
18149 (Disambiguate): The predefined equality on universal_access is not
18150 usable if there is a user-defined equality with the proper signature,
18151 declared in the same declarative part as the designated type.
18152 (Find_Unique_Type): The universal_access equality operator defined under
18153 AI-230 does not cover pool specific access types.
18154 (Covers): If one of the types is a generic actual subtype, check whether
18155 it matches the partial view of the other type.
18157 2006-02-13 Thomas Quinot <quinot@adacore.com>
18159 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
18160 line. This is necessary to allow In_Extended_Main_Unit to provide
18161 correct results for itypes while writing out expanded source.
18162 (Close_File): No need to update the source_index_table here since it's
18163 now done for each line.
18165 2006-02-13 Ed Schonberg <schonberg@adacore.com>
18166 Robert Dewar <dewar@adacore.com>
18168 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
18169 preserve the source unit where the itype is declared, and prevent a
18171 (Note_Implicit_Run_Time_Call): New procedure
18172 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
18175 * sprint.ads: Document use of $ for implicit run time routine call
18177 2006-02-13 Quentin Ochem <ochem@adacore.com>
18179 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
18182 2006-02-13 Bob Duff <duff@adacore.com>
18184 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
18185 Scan_Unsigned, so we do not scan leading blanks and sign twice.
18186 Integer'Value("- 5") and Integer'Value("-+5") now correctly
18187 raise Constraint_Error.
18189 * s-vallli.adb (Scan_Long_Long_Integer): Call
18190 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
18191 do not scan leading blanks and sign twice.
18192 Integer'Value("- 5") and Integer'Value("-+5") now correctly
18193 raise Constraint_Error.
18195 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
18196 Scan_Long_Long_Unsigned): Split out most of the processing from
18197 Scan_Long_Long_Unsigned out into
18198 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
18199 This prevents scanning leading blanks and sign twice.
18200 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
18203 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
18204 out most of the processing from Scan_Unsigned out into
18205 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
18206 This prevents scanning leading blanks and sign twice.
18208 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
18209 use with Modular'Value attribute.
18210 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
18213 2006-02-13 Robert Dewar <dewar@adacore.com>
18215 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value

18408 * a-taster.ads, a-taster.adb: New files.
18410 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
18411 link to the version that does nothing. This way the task termination
18412 routine is not executed twice for the environment task when finishing
18413 because of an unhandled exception.
18415 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
18416 handler because of an unhandled exception.
18418 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
18419 System.Tasking.Utilities instead of that in System.Tasking.Stages.
18421 * s-finimp.adb (initialization code): Modify the soft link for the
18422 finalization of the global list instead of Adafinal.
18424 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
18425 non-tasking version of the soft link for task termination. We do
18426 nothing since if we are using the non-tasking version it
18427 means that the task termination functionality is not used.
18428 (Null_Finalize_Global_List): Add this null version for the procedure
18429 in charge of finalizing the global list for controlled objects.
18430 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
18431 instead for handling run-time termination in a more flexible way.
18432 (Adafinal_NT): This new procedure will take care of finalizing the
18433 global list for controlled objects if needed, but no tasking
18436 * s-tarest.adb (Task_Lock): Do not try to lock again the
18437 Global_Task_Lock if we already own it. Otherwise, we get blocked in
18438 some run-time operations.
18439 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
18440 until all nested locks have been released.
18441 (Task_Wrapper): Call the fall-back task termination handler. It
18442 applies to all tasks but the environment task.
18443 (Finalize_Global_Tasks): Add the call for the task termination
18444 procedure for the environment task.
18445 (Task_Wrapper): suppress warnings around declaration of
18446 Secondary_Stack_Address.
18448 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
18449 moved to the Common_ATCB record.
18450 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
18451 Common_ATCB record.
18452 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
18453 Common_ATCB record.
18455 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
18456 Fall_Back_Handler, and Specific_Handler.
18458 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
18459 defined in Ada.Task_Termination, to avoid circular dependencies.
18460 (Termination_Handler): Redefine this type here, alredy defined in
18461 Ada.Task_Termination, for avoiding circular dependencies.
18462 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
18463 for storing task termination handlers. In addition,
18464 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
18465 Common_ATCB because it is used by both the regular and the restricted
18467 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
18468 Common_ATCB because it is used by both the regular and the restricted
18470 (Common_ATCB): Added a dynamic task analyzer field.
18472 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
18473 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
18474 (Task_Wrapper): Call the task termination handler. It applies to all
18475 tasks but the environment task.
18476 (Finalize_Global_Tasks): Call the task termination procedure for the
18477 environment task. The call to Finalize_Global_List is now performed
18478 using the soft links mechanism.
18479 (Task_Wrapper): added dynamic stack analysis.
18481 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
18482 potentially blocking operations has been moved from
18483 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
18484 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
18485 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
18486 this run-time check.
18488 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
18489 of task termination procedure.
18490 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
18491 link for the task termination procedure.
18493 * bindusg.adb: (Bindusg): Added documentation for -u option.

18507 (Standart_Output): new subprogram
18508 (Set_Output): new subprogram
18509 (Put): now uses the value of Current_Out to know if the output has to be
18510 send to stderr or stdout.
18512 * s-stausa.ads: Complete implementation.
18514 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
18516 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
18517 list of Ada 05 files.
18518 (GNAT Library Units): Add AltiVec files.

18521 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
18522 g-alvety.ads, g-alvevi.ads: New files providing altivec API.
18524 2005-12-09 Nicolas Setton <setton@adacore.com>

18527 file_name is empty.
18529 2005-12-09 Javier Miranda <miranda@adacore.com>
18530 Hristian Kirtchev <kirtchev@adacore.com>
18532 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
18533 to the specification because the frontend generates code that uses this
18535 (Set_Interface_Table): Add missing assertion.
18536 Update documentation describing the run-time structure.
18537 (Displace): New subprogram that displaces the pointer to the object
18538 to reference one of its secondary dispatch tables.
18539 (IW_Membership): Modified to use the new table of interfaces.
18540 (Inherit_TSD): Modified to use the new table of interfaces.
18541 (Register_Interface_Tag): Use the additional formal to fill the
18542 contents of the new table of interfaces.
18543 (Set_Interface_Table): New subprogram that stores in the TSD the
18544 pointer to the table of interfaces.

18558 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
18559 in all the calls to Expand_Interface_Thunk. Instead of referencing the
18560 record component containing the tag of the secondary dispatch table we
18561 have to use the Offset_To_Top run-time function to get this information;
18562 otherwise if the pointer to the base of the object has been displace
18563 we get a wrong value if we use the 'position attribute.
18565 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
18566 all the calls to Expand_Interface_Thunk.
18567 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

18570 ensure that the interfaces implemented by the ancestors are placed
18571 at the header of the generated list.
18572 (Expand_Interface_Conversion): Handle the case in which the displacement
18573 associated with the interface conversion is not statically known. In

18601 RE_TK_Tagged, RE_TK_Task.
18603 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
18604 Init_Secondary_Tags_Internal to allow its use with interface types and
18605 also to generate the code for the new additional actual required
18606 by Set_Offset_To_Top.
18607 (Build_Init_Statements): In case of components associated with abstract
18608 interface types there is no need to generate a call to its IP.
18609 (Freeze_Record_Type): Generate Select Specific Data tables only for
18611 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
18612 the bodies and specifications of the predefined primitive operations

18620 properly protected objects and attach handler in the case of the
18621 restricted profile.

18634 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
18635 pointer initialization values. Make a SAVE_EXPR instead. Add comments
18636 about the use and expansion of SAVE_EXPRs in the various possible
18637 renaming handling cases.
18638 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
18639 abusing DECL_FCONTEXT.

18739 covered by the tag of the source.
18741 2005-12-09 Robert Dewar <dewar@adacore.com>
18743 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean
18744 parameter in call to Image_Wide_Character.

18758 component associated with the secondary table of an abstract interface
18759 type, return the entity associated with such abstract interface type.
18760 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
18761 base type to create anonymous subtype, because entity may be a locally
18762 declared subtype or generic actual.
18763 (Find_Interface): New subprogram that given a tagged type and one of its
18764 component associated with the secondary table of an abstract interface
18765 type, return the entity associated with such abstract interface type.

18768 conversion cannot be handled at compile time. In this case we pass this
18769 information to the expander to generate the appropriate code.

18807 legal within a protected type that implements an interface.
18808 (Collect_Interfaces): Do not add to the list the interfaces that
18809 are implemented by the ancestors.
18810 (Derived_Type_Declaration): If the parent of the full-view is an
18811 interface perform a transformation of the tree to ensure that it has
18812 the same parent than the partial-view. This simplifies the job of the
18813 expander in order to generate the correct object layout, and it is
18814 needed because the list of interfaces of the full-view can be given in
18816 (Process_Full_View): The parent of the full-view does not need to be
18817 a descendant of the parent of the partial view if both parents are
18819 (Analyze_Private_Extension_Declaration): If declaration has an explicit
18820 "limited" the parent must be a limited type.

18834 (Process_Full_View): Improve the check for the "no hidden interface"
18835 rule as defined by AI-396.
18837 2005-12-09 Robert Dewar <dewar@adacore.com>

18894 available user-specified stream attributes on limited parameters to
18895 also test the type directly rather than only its underlying type (for

18897 attributes are visible at the point of the subprogram declaration.
18898 For Ada 2005, the error message is modified to indicate that the

19062 files are not available at this point in a tool bootstrap. Newlib
19063 only has basic C library header files.

19066 Roger Sayle <roger@eyesopen.com>
19069 * misc.c (internal_error_function): Don't use vsprintf to format

19081 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
19082 a temporary if taking the address of something that is neither
19083 reference, declaration, or constant, since the gimplifier

19156 * gen-soccon.c: Complete value expansion should not be performed on
19157 TARGET, as it has the form of a math expression, and some components
19158 may be platform-defined macros.
19159 For VxWorks, generate the OK and ERROR values.
19160 New constants giving the sizes of the components of C struct timeval.

19172 deal with different cases of static and dynamic elaboration checks (all
19173 checks does not count in the first case, but does in the second).

19179 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
19180 elementary types using the operator in standard. It is cleaner not to
19181 modify the programmers intent, especially in the case of floating-point.
19182 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
19183 it did not matter because we always rewrote a/=b to not(a=b).
19184 (Expand_Allocator_Expression): For an allocator expression whose nominal
19185 subtype is an unconstrained packed type, convert the expression to its
19186 actual constrained subtype.
19187 Implement warning for <= or >= where < or > not possible
19188 Fix to Vax_Float tests (too early in many routines, causing premature
19189 Vax_Float expansions.
19191 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
19192 to be used with packages and generic packages as well as with

19195 of pragma Suppress (All_Checks)
19196 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
19197 a string literal for precise control over warnings.

19207 Allow optional = after -gnatm
19208 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
19209 longer sets Elaboration_Checks.
19210 Code to set warning mode moved to Sem_Warn
19211 so that it can be shared by pragma processing.
19213 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
19216 * s-taprop-solaris.adb:
19217 Change some <= to =, to avoid new warning

19223 2005-11-14 Robert Dewar <dewar@adacore.com>
19225 * exp_vfpt.adb: Handle /= case
19226 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
19227 so that we do not get duplicate scaling for fixed point conversions.
19229 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
19231 2005-11-14 Matthew Gingell <gingell@adacore.com>
19233 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
19234 Increase default priority on Lynx from 15 to 17, and meet the Ada
19235 requirement that Default_Priority be ((Priority'First +
19236 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

19333 from a fat or thin pointer type and a constrained object type.
19334 (annotate_value): Handle BIT_AND_EXPR.
19335 (annotate_rep): Don't restrict the back annotation of inherited
19336 components to the type_annotate_only case.

19338 we are not defining the type.
19339 <E_Record_Type>: Likewise.
19340 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
19341 to get advantage of the new maybe_stabilize_reference interface, to
19342 ensure that what we reference is indeed stabilized instead of relying
19343 on assumptions on what the stabilizer does.
19344 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
19345 type imported through a limited_with clause, use its non-limited view.
19346 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
19348 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
19349 of #if sections + explicit comparisons of convention identifiers.

19351 before early-returning for certain types when code generation is
19353 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
19354 nullification of gnu_expr we do for objects with address clause and
19355 that we are not defining.
19356 (elaborate_expression_1): Do not create constants when creating
19357 variables needed by the debug info: the dwarf2 writer considers that
19358 CONST_DECLs is used only to represent enumeration constants, and emits
19360 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
19361 object with an address clause into an indirect reference, drop the
19362 initializing expression.
19364 (STACK_CHECK_BUILTIN): Delete.
19365 (STACK_CHECK_PROBE_INTERVAL): Likewise.

19373 if there is an actual subtype provided by the front-end, use that
19374 subtype to build an actual type with bounds template.
19375 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
19376 is provided by the front-end, use that subtype to compute the size of
19377 the deallocated object.
19378 (gnat_to_gnu): When adding a statement into an elaboration procedure,
19379 check for a potential violation of a No_Elaboration_Code restriction.
19380 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
19381 with extra arguments to control whether to recurse through non-values
19382 and to let the caller know if the stabilization has succeeded.

19384 maybe_stabilize, for common uses without restriction on lvalues and
19385 without need to check for the success indication.
19386 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
19387 pass false instead of 0 as the FORCE argument which is a bool.
19388 (Identifier_to_gnu): Remove checks ensuring that an renamed object
19389 attached to a renaming pointer has been properly stabilized, as no such
19390 object is attached otherwise.
19391 (call_to_gnu): Invoke create_var_decl to create the temporary when the
19392 function uses the "target pointer" return mechanism.
19393 Reinstate conversion of the actual to the type of the formal
19394 parameter before any other specific treatment based on the passing
19395 mechanism. This turns out to be necessary in order for PLACEHOLDER
19396 substitution to work properly when the latter type is unconstrained.

19400 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

19402 and to let the caller know if the stabilization has succeeded.
19404 * utils2.c (gnat_build_constructor): Only sort the fields for possible
19405 static output of record constructor if all the components are constant.
19406 (gnat_build_constructor): For a record type, sort the list of field
19407 initializers in increasing bit position order.
19408 Factor common code to build a storage type for an unconstrained object
19409 from a fat or thin pointer type and a constrained object type.
19410 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
19411 types variants, and process special cases of VIEW_CONVERT expressions
19412 as their NOP_EXPR counterpart to ensure we get to the
19413 CORRESPONDING_VARs associated with CONST_DECls.
19414 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
19415 on the right-hand side.

19422 extracting the object if converting to a type variant.
19423 (create_var_decl): When a variable has an initializer requiring code
19424 generation and we are at the top level, check for a potential violation
19425 of a No_Elaboration_Code restriction.
19426 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
19427 SIZE and SIZE_UNIT which we need for later back-annotations.

19429 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
19430 is an unchecked union.
19431 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
19432 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
19433 main variant, just replace the VIEW_CONVERT_EXPR.

19569 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
19570 for task component, in the case of a limited aggregate. The enclosed

19612 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
19613 'Unrestricted_Access, if the designated type is an interface we
19614 add a type conversion to force the displacement of the pointer

19618 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
19619 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
19620 'Terminated for task interface class-wide objects. Generate a call to
19621 the predefined dispatching routine used to retrieve the _task_id from

19651 the return value into its actual subtype in order to help the backend
19652 to return the actual size instead of the maximum. This is another

19702 attribute of the N_Free_Statement.
19703 Generate itype for classwide designated object in both cases of
19704 user-specified storage pool: specific and class-wide, not only in the
19706 Raise CE when trying to set a not null access type object to null.

19978 view is a transitive derivation of the ancestor of the partial view.
19979 (Process_Full_View): Rename local subprogram Find_Interface_In_
19980 Descendant to Find_Ancestor_Interface to leave the code more clear.
19981 Remove wrong code that avoids the generation of an error message

20038 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
20039 not try to rewrite a renamed stream attribute, because the operations
20040 on the type may not have been generated.

20042 whose default is abstract because the object type itself is abstract.
20043 (Find_Type): If the type is incomplete and appears as the prefix of a
20044 'Class reference, it is tagged, and its list of primitive operations
20045 must be initialized properly.
20046 (Chain_Use_Clauses): When chaining the use clauses that appear in the
20047 private declaration of a parent unit, prior to compiling the private
20048 part of a child unit, find on the scope stack the proper parent entity
20049 on which to link the use clause.

20079 precision float type for the generated code (prevents gratuitous
20080 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
20081 (Resolve_Concatenation_Arg): Improve error message when argument is an
20082 ambiguous call to a function that returns an array.
20083 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

20809 code generated by the expander.
20810 (Expand_Interface_Conversion): If the actual is an access type then
20811 build an internal function to handle the displacement. If the actual
20812 is null this function returns null because no displacement is
20813 required; otherwise performs a type conversion that will be
20814 expanded in the code that returns the value of the displaced actual.
20815 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
20816 conversions that have no effect in the generated code because no

21080 whether a potential circularity is harmless, because it includes units
21081 loaded through a limited_with clause. Extends previous treatment which
21082 did not handle properly arbitrary combinations of limited and
21083 non-limited clauses.
21085 2005-09-01 Nicolas Setton <setton@adacore.com>
21087 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
21088 to be encoded as typ___XBLU_lowerbound__upperbound instead of
21089 typ___XB_lowerbound__upperbound.
21091 2005-09-01 Thomas Quinot <quinot@adacore.com>
21093 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
21094 dummy access formal for RACW/RAS TypeCode TSS.
21095 (Build_TypeCode_Call): Do not generate dummy null access actual for
21096 calls to the TypeCode TSS.
21098 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21100 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
21101 fully qualified name, to distinguish instances with the same local name.
21103 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
21106 2005-09-01 Robert Dewar <dewar@adacore.com>

21111 2005-09-01 Jerome Lambourg <lambourg@adacore.com>
21113 * g-expect.adb (Non_Blocking_Spawn): Initialize the filters field to
21114 (Free): New deallocation procedure for filter elements
21115 (Close): Deallocate any existing filter for the concerned connection
21117 2005-09-01 Laurent Pautet <pautet@adacore.com>
21119 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
21120 position set is provided, we compute one in order to reduce the maximum
21121 length of the keys. This computation first selects a character
21122 position between 1 and the minimum length of the keys in order to
21123 avoid reducing one of the keys to an empty string.
21124 (Initialize, Compute): When the ratio V to K is too low, the algorithm
21125 does not converge. The initialization procedure now comes with a
21126 maximum number of iterations such that when exceeded, an exception is
21127 raised in Compute. The user can initialize this ratio to another value
21129 Reformating and updated headers.
21131 2005-09-01 Javier Miranda <miranda@adacore.com>
21133 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
21134 that given an entity T creates and returns an Itype that duplicates the
21135 contents of T. The returned Itype has the null-exclusion
21136 attribute set to True, and its Etype attribute references T
21137 to keep the association between the two entities.
21138 Update copyright notice
21140 * sem_aggr.adb (Check_Can_Never_Be_Null,
21141 Aggregate_Constraint_Checks, Resolve_Aggregate,
21142 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
21144 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

21147 Robert Dewar <dewar@adacore.com>
21148 Hristian Kirtchev <kirtchev@adacore.com>
21150 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
21153 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
21155 Call Set_Result_Definition instead of Set_Subtype_Mark.
21156 (P_Subprogram_Specification): Add parsing of anonymous access result
21157 plus null exclusions. Call Set_Result_Definition instead of
21160 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
21161 (P_Access_Type_Definition): Add parsing for an anonymous access result
21162 subtype, plus parsing for null exclusions. Call Set_Result_Definition
21163 instead of Set_Subtype_Mark.
21165 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
21166 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
21167 (Result_Definition): New function for N_Function_Specifications.
21168 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
21169 N_Function_Specification.
21170 (Set_Null_Exclusion_Present): Allow this flag for
21171 N_Function_Specification.
21172 (Set_Result_Definition): New procedure for N_Function_Specifications.
21173 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
21174 and N_Function_Specification.
21176 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
21177 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
21178 Add support for LIMITED NEW for Ada 2005 AI-419
21179 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
21180 syntax for anonymous access results.
21181 Replace Subtype_Mark field by Result_Definition in
21182 N_Function_Specification and N_Access_Definition specs.
21183 Add Null_Exclusion_Present to spec of N_Function_Specification.
21184 (Result_Definition): New function for N_Function_Specification and
21185 N_Access_Function_Definition.
21186 (Set_Result_Definition): New procedure for N_Function_Specification and
21187 N_Access_Function_Definition.
21189 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
21190 Result_Definition for cases of N_Access_Function_Definition and
21191 N_Function_Specification.
21192 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
21194 2005-09-01 Vincent Celier <celier@adacore.com>
21196 * lib-writ.adb: Update Copyright notice
21197 (Write_With_Lines): On platforms where file names are case-insensitive,
21198 record the file names in lower case.
21199 (Write_ALI): For D lines, on platforms where file names are
21200 case-insensitive, record the file names in lower case.
21202 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21203 Emmanuel Briot <briot@adacore.com>
21205 * lib-xref.adb (Output_Overridden_Op): Display information on
21206 overridden operation.
21208 * lib-xref.ads: Add documentation on overridden operations.
21210 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
21213 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
21214 overriding entity information.
21216 2005-09-01 Vincent Celier <celier@adacore.com>
21218 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
21219 including those that are inherited.
21221 2005-09-01 Robert Dewar <dewar@adacore.com>
21223 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
21225 * par-prag.adb: Implement new pragma Debug_Policy
21227 * sem_prag.adb Implement new pragma Debug_Policy
21228 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
21229 Component_Size attribute specification. Give warning for ignored pragma
21232 * snames.h, snames.ads, snames.adb: Introduce entries in
21233 Preset_Names for Name_Disp_Asynchronous_Select,
21234 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
21235 Name_Disp_Timed_Select.
21236 New pragma Debug_Policy
21238 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
21240 Switch -gnata also sets Debug_Pragmas_Enabled
21242 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
21243 handle an explicit -gnata when compiling predefined files.
21245 2005-09-01 Vincent Celier <celier@adacore.com>
21247 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
21248 directories of projects that have no Ada sources.
21250 2005-09-01 Robert Dewar <dewar@adacore.com>
21252 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
21253 (makes a difference for wide characters)
21255 * widechar.adb, widechar.ads:
21256 Add Wide_Char_Byte_Count feature to count chars vs bytes
21258 2005-09-01 Thomas Quinot <quinot@adacore.com>
21259 Ed Schonberg <schonberg@adacore.com>
21260 Robert Dewar <dewar@adacore.com>
21262 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
21263 'Address attribute reference with an overloaded prefix, use the
21264 location of the prefix (not the location of the attribute reference) as
21265 the error location.
21266 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
21267 a function renaming thereof, is a valid prefix for 'Size (where it is
21268 intepreted as a function call).
21269 (Statically_Denotes_Entity): New predicate to determine whether the
21270 prefix of an array attribute can be considered static.
21273 (Eval_Attr): Fix failure to evaluate Component_Size for
21274 unconstrained arrays (resulted in wrong value in packed case, since
21275 back end cannot handle this case)
21277 2005-09-01 Robert Dewar <dewar@adacore.com>
21279 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
21280 error msgs for most common cases.
21281 Use new errout insertion char < (conditional warning)
21283 2005-09-01 Javier Miranda <miranda@adacore.com>
21284 Ed Schonberg <schonberg@adacore.com>
21286 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
21287 become local to the whole package.
21288 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
21289 the package was already analyzed the new algorithm "replaces" the
21290 real entities by the shadow ones. This is required to ensure that
21291 the order of these entities in the homonym chains does not change;
21292 otherwise we can have undefined references at linking time because
21293 in case of conflicts the external name of the entities will have
21294 a suffix that depends on the order of the entities in the chain.
21295 (Remove_Limited_With_Clause): Complementary code that completes the
21296 new algorithm and replaces the shadow entities by the real ones.
21297 (Install_Limited_Withed_Unit): When unchaining entities before the
21298 installation of the shadow entities, only regular entities of the
21299 public part must be taken into account. This is required to
21300 keep this routine in synch with the work done by Remove_Limited_
21302 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
21303 even if unit is analyzed, because the analysis of the unit is
21304 idempotent in any case, and the limited view of the unit may have to
21305 be installed for proper visibility.
21306 (Expand_Limited_With_Clause): Even if the unit in the implicit
21307 with_clause has been analyzed already, a limited view of the package
21308 must be built for the current context, if it does not exist yet.
21310 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21311 Javier Miranda <miranda@adacore.com>
21312 Gary Dismukes <dismukes@adacore.com>
21314 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
21315 defining entity for the instance body, make a new defining identifier
21316 rather than copying the entity of the spec, to prevent accidental
21317 sharing of the entity list.
21318 (Check_Private_View): When exchanging views of private types, build the
21319 list of exchanged views as a stack, to ensure that on exit the exchanges
21320 are undone in the proper order.
21321 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
21322 Restore the compilation environment in case of instantiation_error.
21323 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
21324 for an anonymous access result.
21325 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
21326 (Formal_Entity): Handle properly the case of a formal package that
21327 denotes a generic package renaming.
21329 2005-09-01 Thomas Quinot <quinot@adacore.com>
21331 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
21332 clause if the array aggregate is surrounded by parentheses.
21334 2005-09-01 Cyrille Comar <comar@adacore.com>
21335 Gary Dismukes <dismukes@adacore.com>
21336 Ed Schonberg <schonberg@adacore.com>
21337 Javier Miranda <miranda@adacore.com>
21339 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
21341 to check if a type is Constrained in cases related to code generation
21342 (rather than semantic checking) since otherwise we do not generate
21343 similar code for mutable private types depending if their
21344 discriminants are visible or not.
21345 (Check_Abstract_Overriding): Do not complain about failure to override
21346 the primitive operations used in dispatching selects since they will
21347 always be overriden at the freeze point of the type.
21348 (Access_Definition): Separate out handling for resetting the scope
21349 of an anonymous access function result type. Retrieve the scope
21350 of the associated function rather than using Current_Scope, which
21351 does not have a consistent value (depends on whether we're in the
21352 middle of analyzing formal parameters). Add ??? comment about
21353 finding a cleaner way to handle the special cases of scope setting.
21354 (Process_Incomplete_Dependents): A protected operation is never a
21355 dispatching operation (only its wrapper may be).
21356 (Build_Derived_Record_Type): In case of tagged private types that
21357 implement interfaces add derivation of predefined primitive
21359 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
21360 by two parameters that are used in case of derivation from abstract
21361 interface types: No_Predefined_Prims is used to avoid the derivation
21362 of predefined primitives from the interface, and Predefined
21363 Prims_Only is used to complete the derivation predefined primitives
21364 in case of private tagged types implementing interfaces.
21365 Fix typo in comments
21366 (Find_Interface_In_Descendant): Protect the frontend against
21367 wrong code with large circularity chains.
21368 (Is_Private_Overriding): Add support for entities overriding interface
21369 subprograms. The test failed because Entities associated with overriden
21370 interface subprograms are always marked as hidden (and used to build
21371 the secondary dispatch table); in this case the overriden entity is
21372 available through the field abstract_interface_alias (cf. override_
21373 dispatching_operation)
21374 (Access_Definition): Set the scope of the type to Current_Scope for the
21375 case of a function with an anonymous access result type.
21376 (Access_Subprogram_Declaration): Handle creation of the type entity for
21377 an access-to-function type with an anonymous access result.
21378 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
21379 in handling for N_Access_Function_Definition.
21380 (Analyze_Subtype_Declaration): Modify the text of error message.
21381 (Derived_Type_Declaration): Modify the text of error message.
21382 (Process_Subtype): Modify the text of error message plus cleanup
21383 of one redundant error message.
21384 (Analyze_Component_Declaration): Code cleanup.
21385 (Analyze_Object_Declaration): Code cleanup.
21386 (Analyze_Subtype_Declaration): Propagate the null-exclusion
21387 attribute in case of access types. Code cleanup.
21388 (Array_Type_Declaration): Code cleanup.
21389 (Process_Discriminants): Create the new null-excluding itype
21390 if required. Code cleanup.
21391 (Process_Subtype): Create the new null-excluding itype if
21392 required. Code cleanup.
21393 (Build_Derived_Record_Type): Code cleanup to avoid calling
21394 twice the subprogram derive_subprograms in case of private
21395 types that implement interfaces. In this particular case the
21396 subprogram Complete_Subprograms_Derivation already does the
21397 job associated with the second call.
21399 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
21400 conversion to the full view when generating an operation for a
21401 discriminant whose type may currently be private.
21403 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21404 Javier Miranda <miranda@adacore.com>
21406 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
21407 V (Obj.F), the rewriting does not involve the indexed component, but
21408 only the selected component itself.
21409 Do not apply the transformation if the analyzed node is an actual of a
21410 call to another subprogram.
21411 (Complete_Object_Operation): Retain the entity of the
21412 dispatching operation in the selector of the rewritten node. The
21413 entity will be used in the expansion of dispatching selects.
21414 (Analyze_One_Call): Improve location of the error message associated
21416 (Analyze_Selected_Component): No need to resolve prefix when it is a
21417 function call, resolution is done when parent node is resolved, as
21419 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
21420 when attempting to resolve a call transformed from its object notation.
21421 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
21422 of the argument list for each interpretation of the operation.
21423 (Try_Object_Operation): The designated type of an access parameter may
21424 be an incomplete type obtained through a limited_with clause, in which
21425 case the primitive operations of the type are retrieved from its full
21427 (Analyze_Call): If this is an indirect call, and the return type of the
21428 access_to_subprogram is incomplete, use its full view if available.
21430 2005-09-01 Javier Miranda <miranda@adacore.com>
21431 Gary Dismukes <dismukes@adacore.com>
21433 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
21434 access types the null-exclusion and access-to-constant attributes must
21436 (Analyze_Return_Statement): When the result type is an anonymous access
21437 type, apply a conversion of the return expression to the access type
21438 to ensure that appropriate accessibility checks are performed.
21439 (Analyze_Return_Type): For the case of an anonymous access result type,
21440 generate the Itype and set Is_Local_Anonymous_Access on the type.
21441 Add ??? placeholder for check to disallow returning a limited object
21442 in Ada 2005 unless it's an aggregate or a result of a function call.
21443 Change calls from Subtype_Mark to Result_Definition.
21444 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
21445 Result_Definition in call to Make_Function_Specification.
21446 (Build_Body_To_Inline): Change Set_Subtype_Mark to
21447 Set_Result_Definition.
21448 (Make_Inequality_Operator): Change formal Subtype_Mark to
21449 Result_Definition in call to Make_Function_Specification.
21450 (Process_Formals): Create the new null-excluding itype if required.
21451 (New_Overloaded_Entity): For an entity overriding an interface primitive
21452 check if the entity also covers other abstract subprograms in the same
21453 scope. This is required to handle the general case, that is, overriding
21454 other interface primitives and overriding abstract subprograms inherited
21455 from some abstract ancestor type.
21456 (New_Overloaded_Entity): For an overriding entity that comes from
21457 source, note the operation that it overrides.
21458 (Check_Conformance, Type_Conformant): Addition of one new formal
21459 to skip controlling formals in the analysis. This is used to
21460 handle overloading of abstract interfaces.
21461 (Base_Types_Match): Add missing case for types imported from
21462 limited-with clauses
21463 (New_Overloaded_Entity): Add barrier to protect the use of
21464 the "alias" attribute.
21466 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21468 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
21469 verify that the procedure and the entry are mode conformant.
21470 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
21471 as a different operator, which is often a cut-and-paste error.
21473 2005-09-01 Javier Miranda <miranda@adacore.com>
21474 Ed Schonberg <schonberg@adacore.com>
21476 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
21477 used in controlling parameters exclude null because it is necessary to
21478 read the tag to dispatch, and null has no tag.
21479 (Override_Dispatching_Operation): If the previous operation is inherited
21480 from an interface, it becomes hidden and does not participate in later
21483 2005-09-01 Javier Miranda <miranda@adacore.com>
21484 Ed Schonberg <schonberg@adacore.com>
21485 Gary Dismukes <dismukes@adacore.com>
21487 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
21488 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
21489 the expander will generate the corresponding run-time check to evaluate
21491 (Resolve_Call): Check for legal type of procedure name or prefix that
21492 appears as a trigger in a triggering alternative.
21493 (Valid_Conversion): If expression is ambiguous and the context involves
21494 an extension of System, remove System.Address interpretations.
21495 (Resolve_Qualified_Expression): Reject the case of a specific-type
21496 qualification applied to a class-wide argument. Enhance comment
21497 to explain checking of Original_Node.
21498 (Resolve_Type_Conversion): The location of the error message was not
21499 general enough to handle the general case and hence it has been removed.
21500 In addition, this patch improves the text of the message.
21501 (Resolve_Type_Conversion): Add missing support for access to interface
21503 (Resolve_Type_Conversion): If the target is a class-wide interface type,
21504 do not expand if the expression is the actual in a call, because proper
21505 expansion will take place when the call itself is expanded.
21506 (Resolve_Allocator): If the context is an unchecked conversion, the
21507 allocator inherits its storage pool, if any, from the target type of
21510 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21511 Javier Miranda <miranda@adacore.com>
21513 * sem_type.adb (Add_One_Interp): If a candidate operation is an
21514 inherited interface operation that has an implementation, use the
21515 implementation to avoid spurious ambiguities.
21516 (Interface_Present_In_Ancestor): In case of concurrent types we can't
21517 use the Corresponding_Record_Typ attribute to look for the interface
21518 because it is set by the expander (and hence it is not always
21519 available). For this reason we traverse the list of interfaces
21520 (available in the parent of the concurrent type).
21521 (Interface_Present_In_Ancestor): Handle entities from the limited view
21523 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21525 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
21526 from the list of required components.
21527 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
21528 primitive procedure of a limited interface with a controlling first
21530 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
21532 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
21533 capture if it is generated in the second operand of a short-circuit
21535 Do not capture values for variables with address clauses.
21536 (Is_Object_Reference): Treat a function call as an object reference only
21537 if its type is not Standard_Void_Type.
21539 2005-09-01 Ed Schonberg <schonberg@adacore.com>
21541 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
21542 to a variable that is statically known to be constant.
21544 2005-09-01 Geert Bosch <bosch@adacore.com>
21545 Robert Dewar <dewar@adacore.com>
21547 * ttypef.ads (VAXDF_Safe_First): Use correct value for constant.
21548 (VAXGF_Safe_First): Idem.

22765 If the program has a null default, generate an empty body for it.
22767 * sem_ch6.adb, sem_ch9.adb (Analyze_Subprograms_Declaration): Update
22768 error message condition, null procedures are correctly detected now.
22769 (New_Overloaded_Entity): Bypass trivial overriding indicator check

22771 indicator is examined in Sem_Ch9 while analysing the subprogram
22773 (Check_Overriding_Indicator): Check consistency of overriding indicator
22774 on subprogram stubs as well.
22775 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
22777 (Analize_Subprogram_Specification): When analyzing a subprogram in which

22779 by the corresponding record type.
22780 (Analyze_Subprogram_Body): Undo the previous work.
22781 (Analyze_Procedure_Call): If the call has the form Object.Op, the

22790 access to subprograms must be recursive.
22791 (Is_Unchecked_Conversion): Improve the test that recognizes
22792 instantiations of Unchecked_Conversion, and allows them in bodies that
22793 are to be inlined by the front-end. When the body comes from an
22794 instantiation, a reference to Unchecked_Conversion will be an
22795 Expanded_Name, even though the body has not been analyzed yet.

22814 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
22815 in the case where the target type is an anonymous access type of an
22816 object or component (that is, when Is_Local_Anonymous_Access is true).
22817 Prevent the special checks for conversions of access discriminants in
22818 the case where the discriminant belongs to a nonlimited type, since
22819 such discriminants have their accessibility level defined in the same
22820 way as a normal component of an anonymous access type.
22821 (Resolve_Allocator): When an allocator's designated type is a class-wide
22822 type, check that the accessibility level of type given in the
22823 allocator's expression or subtype indication is not statically deeper
22824 than the level of the allocator's access type.
22825 (Check_Discriminant_Use): Diagnose discriminant given by an expanded
22826 name in a discriminant constraint of a record component.

22835 (Resolve_Actuals): Enable full error reporting on view conversions
22836 between unrelated by_reference array types.
22837 The rule for view conversions of arrays with aliased components is
22838 weakened in Ada 2005.
22839 Call to obsolescent subprogram is now considered to be a violation of
22840 pragma Restrictions (No_Obsolescent_Features).
22841 (Check_Direct_Boolean_Operator): If the boolean operation has been
22842 constant-folded, there is nothing to check.
22843 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
22844 check on possible violation of restriction No_Direct_Boolean_Operators
22845 until after expansion of operands, to prevent spurious errors when

22880 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
22881 both bound checks, rather than a conjunction.
22882 (Insert_Valid_Check): If the expression is an actual that is an indexed
22883 component of a bit-packed array, force expansion of the packed element
22884 reference, because it is specifically inhibited elsewhere.

23268 (Get_Type_Reference): For a subtype that is the renaming of an actual in
23269 an instantiation, use the first_subtype to ensure that we don't generate
23270 cross-reference information for internal types.

23850 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
23851 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
23852 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
23853 analyzed if expansion is disabled (which could otherwise cause spurious
23854 error messages if expansion has been disabled due to previous
23855 (unrelated) errors).
23857 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
23858 is disabled, the entity denoted by the argument is the access type
23859 itself, not an underlying record type, so there is no need to go back
23860 to the Corresponding_Remote_Type.
23862 2005-03-29 Gary Dismukes <dismukes@adacore.com>
23863 Robert Dewar <dewar@adacore.com>
23865 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
23866 expand a call to an instance of
23867 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the

23869 check is also generated, to ensure that the tag passed to the instance
23870 denotes a type in the class.
23871 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
23872 of Name_Generic_Dispatching_Constructor.
23874 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
23875 05 unit for AI-260-02).

23889 the case of renaming of stream attributes when the renaming denotes a
23890 generic formal subprogram association for an abstract formal subprogram.
23891 Check that the attribute is a primitive stream attribute (and not
23892 a class-wide stream attribute) and then rewrite the attribute name
23893 as the name of the appropriate compiler-generated stream primitive.
23895 2005-03-29 Robert Dewar <dewar@adacore.com>
23897 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

23905 itype whose parent is controlled and not yet frozen, do not create a
23906 freeze node for the itype if expansion is disabled.
23908 2005-03-29 Vincent Celier <celier@adacore.com>
23910 * make.adb (Gnatmake): Don't fail if the main project file is declared
23911 as having no Ada sources. Do not display message "no sources to
23912 compile" in quiet output.
23914 2005-03-29 Doug Rupp <rupp@adacore.com>
23916 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

23932 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
23933 rather than proceed ahead using a junk attribute name.
23935 2005-03-29 Vincent Celier <celier@adacore.com>
23937 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
23939 * prj-part.adb (Parse_Single_Project): Set the location of a project
23940 on its defining identifier, rather than on the reserved word "project".
23942 * prj-proc.adb (Expression): Adapt to the fact that default of external
23943 references may be string expressions, not always literal strings.
23944 (Recursive_Process): Set Display_Name equal to Name
23945 when Location is No_Location, that is when there is no actual file.
23946 Get the Display_Name of the project from the source, when it is not a
23948 (Process): Use the Display_Name in error messages
23950 * prj-strt.adb (External_Reference): Allow default to be string
23951 expressions, not only literal strings.
23953 2005-03-29 Vincent Celier <celier@adacore.com>

23960 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
23961 forbid conversion of a local access-to-subprogram type to a remote one.
23963 * sem_util.adb (Wrong_Type): For a record type that is the expanded
23964 equivalent type for a remote access-to-subprogram type, go back to the
23965 original RAS entity when displaying an error message, so the casing is
23966 the original source casing.

23970 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
23973 2005-03-29 Ed Schonberg <schonberg@adacore.com>
23975 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
23976 subtype if code is being pre-analyzed, to prevent un-expanded
23977 references to protected formals, among others.
23978 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
23979 interpretation that can be a call, include the result of the call as a
23980 possible interpretation of the dereference.
23982 * sem_ch5.adb (Process_Bounds): Determine type of range by
23983 pre-analyzing a copy of the original range, and then analyze the range
23984 with the expected type.
23986 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
23987 with an overloaded prefix where not all interpretations yield an
23988 access to subprogram, do not rewrite node as a call.
23989 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
23990 the node as a call once the context identifies the interpretation of
23991 the prefix whose call yields the context type.
23992 (Valid_Conversion): For the case of a conversion between
23993 local access-to-subprogram types, check subtype conformance using
23994 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
23995 detailed error message.

23999 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
24000 indicator, indicate that the formal can never be null.
24001 (Process_Formals): If a formal has a non_null indicator, insert the
24002 resulting subtype immediately before the enclosing subprogram decl,
24003 and not at the beginning of the corresponding declarative part, to
24004 prevent access before elaboration (Ada2005).

24113 to install the visible declarations of the enclosing scope of a
24114 record_type_with_private to establish the proper visibility before
24115 freezing the entity and related subprograms.

24125 (Check_Stream_Attribute): Move the code for 13.13.2(9/1) enforcement
24126 into a new Check_Attr subprogram, in order to provide a more
24127 explanatory error message (including the name of the missing attribute).
24128 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
24129 subprogram determines whether a default implementation exists for a
24130 given stream attribute.
24131 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
24132 Determine whether to generate a default implementation for each stream
24133 attribute separately, as this depends on the specific attribute.
24135 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
24136 limited extension where a stream attribute is missing for a limited
24137 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

24670 These subprogram have been removed because the attribute
24671 Task_Body_Procedure has been moved to the corresponding task type
24672 or task subtype entity to leave a field free to store the list
24673 of interfaces implemented by a task (for AI-345)
24674 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
24675 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
24676 expression flag Do_Range_Check
24677 (Exception_Junk): Change to Flag7 to accomodate above change
24678 (Box_Present, Default_Name, Specification, Set_Box_Present,
24679 Set_Default_Name, Set_Specification): Expand the expression
24680 "X in N_Formal_Subprogram_Declaration" into the corresponding
24681 two comparisons. Required to use the csinfo tool.
24683 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
24684 "with string" given.
24686 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
24689 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
24692 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
24693 attribute Task_Body_Procedure rather than the old semantic field that
24694 was available in the task_type_declaration node.
24696 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
24697 interface type definitions.
24698 (P_Formal_Derived_Type_Definition): Modified to handle the list of
24701 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
24702 task type declaration.
24703 (P_Protected): Modified to handle the list of interfaces in a
24704 protected type declaration.
24706 2005-03-15 Doug Rupp <rupp@adacore.com>
24707 Vincent Celier <celier@adacore.com>
24709 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
24710 (Gen_Output_File_C): Likewise.
24711 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
24713 2005-03-15 Thomas Quinot <quinot@adacore.com>
24715 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
24716 is an N_Raise_Constraint_Error node, create a new copy of it without
24717 going through a call to Duplicate_Subexpr.
24719 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
24720 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24721 Nicolas Setton <setton@adacore.com>
24722 Ed Schonberg <schonberg@adacore.com>
24728 * decl.c (gnat_to_gnu_field): Reject aliased components with a
24729 representation clause that prescribes a size not equal to the rounded
24730 size of their types.
24731 (gnat_to_gnu_entity, case E_Component): Always look at
24732 Original_Record_Component if Present and not the entity.
24733 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
24734 of tagged extension types by not making field for components that are
24736 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
24737 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
24738 expression to the type of the object when the object is constant.
24739 Reverse defer_debug_incomplete_list before traversing it, so that trees
24740 are processed in the order at which they were added to the list. This
24741 order is important when using the stabs debug format.
24742 If we are deferring the output of debug information, also defer this
24743 output for a function return type.
24744 When adding fields to a record, prevent emitting debug information
24745 for incomplete records, emit the information only when the record is
24747 (components_to_record): New parameter defer_debug.
24748 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
24749 (gnat_to_gnu_field_decl): New function.
24750 (substitution_list, annotate_rep): Call it.
24751 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
24752 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
24753 No longer update discriminants to not be a COMPONENT_REF.
24754 (copy_alias_set): Strip padding from input type; also handle
24755 unconstrained arrays properly.
24757 * gigi.h (write_record_type_debug_info): New function.
24758 Convert to use ANSI-style prototypes. Remove unused
24759 declarations for emit_stack_check, elab_all_gnat and
24760 set_second_error_entity.
24761 (gnat_to_gnu_field_decl): New decl.
24763 * utils.c (write_record_type_debug_info): New function.
24764 (finish_record_type): Delegate generation of debug information to

24766 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
24767 (update_pointer_to): Fix pasto.
24768 (convert) <UNION_TYPE>: Accept slight type variations when
24769 converting to an unchecked union type.
24771 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
24772 replace the N_Freeze_Entity with a null statement.
24774 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
24775 within a constrained subcomponent of an enclosing record, place the
24776 freeze nodes in the scope stack entry for the enclosing record.
24777 (Undelay_Type): New Subprogram.
24778 (Set_Small_Size): Pass T, the type to modify; all callers changed.
24779 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
24780 within records; allow them to have freeze nodes if their base types
24783 * exp_util.adb (Remove_Side_Effects): Properly test for
24784 Expansion_Delayed and handle case when it's inside an
24785 N_Qualified_Expression.
24787 * sem_ch3.adb (Derived_Type_Declaration): New predicate
24788 Comes_From_Generic, to recognize accurately that the parent type in a
24789 derived type declaration can be traced back to a formal type, because
24790 it is one or is derived from one, or because its completion is derived
24792 (Constrain_Component_Type): If component comes from source and has no
24793 explicit constraint, no need to constrain in in a subtype of the
24795 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
24796 Minor change to propagate Is_Ada_2005 flag
24798 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
24799 Expansion_Delayed is False.
24800 (assoc_to_constructor): Ignore fields that have a
24801 Corresponding_Discriminant.
24802 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
24803 function returns "by target", dereference the target pointer using the
24804 type of the actual return value.
24805 <all>: Be prepared for a null gnu_result.
24806 (processed_inline_subprograms): Check flag_really_no_inline
24807 instead of flag_no_inline.
24808 (set_second_error_entity): Remove unused function.

24813 2005-03-15 Robert Dewar <dewar@adacore.com>
24814 Ed Schonberg <schonberg@adacore.com>
24815 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
24817 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
24818 Must_Be_Byte_Aligned for cases where we do not need to use a
24819 System.Pack_nn unit.
24821 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
24823 Needed now that we do some processing for IN parameters as well. This
24824 may well fix some unrelated errors.
24825 (Expand_Call): Handle case of unaligned objects (in particular those
24826 that come from packed arrays).
24827 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
24828 renamed entity is an inherited operation, re-expand the call using the
24829 original operation, which is the one to call.
24830 Detect attempt to inline parameterless recursive subprogram.
24831 (Represented_As_Scalar): Fix to work properly with private types
24832 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
24833 accurate estimate. Yields True in far fewer cases than before,
24834 improving the quality of code that depends on this test.
24836 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
24837 over both visible and private declarations to remove them from tree,
24838 and mark subprograms declared in package as eliminated, to prevent
24839 spurious use in subsequent compilation of generic units in the context.
24841 * exp_util.ads: Minor cleanup in variable names
24843 * sem_eval.ads, sem_eval.adb: Minor reformatting
24844 (Compile_Time_Known_Bounds): New function
24846 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24848 * exp_ch7.adb (Convert_View): Use base types of underlying types when
24849 determining whether an unchecked conversion is needed for the argument
24850 of an initialization call.
24852 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24854 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
24855 that appears in the instantiation rather than the internal subtype
24856 generated in the wrapper package, to avoid anomalies in gigi when the
24857 target is derived from a private type whose full view is an access type.
24859 2005-03-15 Robert Dewar <dewar@adacore.com>
24861 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
24863 Add documentation to replace the use of this flag
24864 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
24867 2005-03-15 Thomas Quinot <quinot@adacore.com>
24869 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
24870 here from exp_attr so it can be shared between exp_attr and exp_dist.
24871 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
24872 all TSS names, not a subset thereof, and the previous name introduced
24873 an unnecessarily confusion that a distinction might exist between
24874 "OK" TSS names and some "not OK" TSS names.
24876 2005-03-15 Doug Rupp <rupp@adacore.com>
24878 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
24881 2005-03-15 Pascal Obry <obry@adacore.com>
24882 Eric Botcazou <ebotcazou@adacore.com>
24886 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
24887 when IN_RTS. This is to work around a bootstrap path problem.
24889 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
24890 table and pass it to __gnat_install_SEH_handler().
24891 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
24893 * lang.opt: Fix specification of -fRTS=.
24895 2005-03-15 Doug Rupp <rupp@adacore.com>

24897 Vincent Celier <celier@adacore.com>
24898 Arnaud Charlet <charlet@adacore.com>
24901 This change works fine when gnatlib is built from the gcc directory,
24902 but does not work when using the libada Makefile, since GCC_FOR_TARGET
24903 is not passed to ada/Makefile.in, so more work is needed by a
24904 Makefile/configure expert.
24906 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
24907 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
24908 Setup gnatlink switch -M for x86_64 linux, as it is already setup
24910 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
24911 Run ranlib on libgccprefix.a
24912 Define PREFIX_OBJS for Darwin, to build libgccprefix.
24913 (ADA_INCLUDE_SRCS): Split Ada packages.
24915 2005-03-15 Robert Dewar <dewar@adacore.com>
24917 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
24919 * impunit.adb: Add GNAT.UTF_32
24921 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
24923 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
24924 now uses GNAT.UTF_32).
24926 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
24927 capabilities for categorizing characters using Unicode categories
24929 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24931 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
24932 instantiation that has been rewritten as a package body, retrieve spec
24933 to generate proper name for implicit_with_clause.
24934 (Install_Parents): Recognize a parent that is an instantiation but has
24935 been rewritten as a package declaration during analysis.
24937 2005-03-15 Javier Miranda <miranda@adacore.com>
24938 Ed Schonberg <schonberg@adacore.com>
24940 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
24941 parameter reported some error we immediately return. This improves the
24942 behaviour of the frontend in case of errors.
24943 (Install_Parent, Remove_Parent): Introduce new flag
24944 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
24945 ancestor of a generic child unit, when the child is being instantiated.
24946 (Inline_Instance_Body): If we are compiling the private
24947 part or the body of a child unit, restore the proper visibility of the
24948 parents after compiling the instance body.
24950 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24951 Javier Miranda <miranda@adacore.com>
24954 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
24955 of a private type, in which case it is underlying_type that denotes
24956 the proper task. Also modified to use the new entity attribute
24957 that is directly available in the task type and task subtype entities
24958 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
24959 arrays when other dimensions than the first are constrained by
24960 discriminants of an enclosing record.
24961 (Insert_Explicit_Dereference): If the prefix is an indexed component or
24962 a combination of indexed and selected components, find ultimate entity
24963 and generate the appropriate reference for it, to suppress spurious
24965 (Note_Possible_Modification): If an entity name has no entity, return.
24966 (Is_Variable): A function call never denotes a variable.
24967 (Requires_Transient_Scope): For record types, recurse only on
24968 components, not on internal subtypes that may have been generated for
24969 constrained components.
24971 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24973 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
24974 Eliminated as candidates for resolution. Both efficient, and avoids
24975 anomalies with operators declared in deleted code.
24976 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
24977 expansion is disabled (as when compiling a generic) to prevent spurious
24978 warnings on prefixes of selected components.
24980 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24982 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
24983 attached to a list before checking whether it appears in the private
24984 declarations of the current package.
24985 (Make_Inequality_Operator): Insert declaration in proper declarative
24986 list rather than just setting the Parent field, so that
24987 Is_Private_Declaration can handle it properly.
24989 2005-03-15 Ed Schonberg <schonberg@adacore.com>
24991 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
24992 a renaming a body, check that the renamed subprogram in not intrinsic.
24993 (Find_Direct_Name): If several use_visible entities hide
24994 each other, and the context is a predefined file compiled through
24995 rtsfind, keep only the entity that comes from a predefined file.
24997 2005-03-15 Geert Bosch <bosch@adacore.com>
24999 * s-fatgen.adb (Valid): Extend special exceptions to account for long
25000 long float padding to also cover AMD64 and IA64.
25002 2005-03-15 Gary Dismukes <dismukes@adacore.com>
25004 * s-imgwch.adb: Add with and use of Interfaces.
25005 (Img_Wide_Character): Change type of Val to Unsigned_16.
25006 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
25008 2005-03-15 Matthew Gingell <gingell@adacore.com>
25010 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
25012 2005-03-15 Robert Dewar <dewar@adacore.com>

25016 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
25018 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
25020 2005-03-15 Robert Dewar <dewar@adacore.com>

25044 procedures in the bug boxes for various GNAT builds.
25046 2005-03-15 Vincent Celier <celier@adacore.com>
25048 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

25054 Sergey Rybin <rybin@adacore.com>
25056 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
25057 too specific and long-winded to be appropriate for the GNAT User's
25059 Warn about use of GCC switches not documented in the GNAT User's Guide,
25060 as these may cause generated code to not conform to Ada semantics.
25061 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
25062 Add documentation for -gnat95 and -gnat05 switches
25063 Remove paragraph documenting obsolete way to refer to third party
25065 Add a few references to Ada_05 that were missing.
25066 Update documentation on -gnatZ/-gnatL.
25067 Document limitation when using -m64 under Solaris.

25111 we asked for an unknown mode.
25113 2005-02-12 Richard Henderson <rth@redhat.com>
25115 * utils.c (gnat_type_for_mode): Return NULL for COMPLEX modes;

25482 the formal subprogram.
25483 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
25484 which is an unclean use of that field, we set the new field

25508 as the tagged type for the cases of abstract formal subprograms and
25509 renamings of those. Clean up spec comments.

25511 procedure", covering the case of a call to a formal abstract procedure
25512 that has statically tagged operands.

25514 a tag-indeterminate function call whose type is an ancestor of the
25515 containing call's associated tagged type. This situation can occur

25630 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
25631 unchecked union with no inferable discriminants, return a
25632 Raise_Program_Error node, rather than inserting it at the point the
25634 (Expand_Record_Equality, Component_Equality): Handle properly the case
25635 where some subcomponent is an unchecked union whose generated equality
25636 code raises program error.
25638 2005-02-09 Doug Rupp <rupp@adacore.com>
25640 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.
25641 [VMS] (#define exit hack): Remove.
25643 2005-02-09 Pascal Obry <obry@adacore.com>
25644 Arnaud Charlet <charlet@adacore.com>
25646 * init.c (__gnat_initialize): Add a new parameter eh which contains the
25647 address of the exception registration. The Win32 version of this
25648 routine calls __gnat_install_SEH_handler() to initialize the SEH
25649 (Structured Exception Handling) handler.
25650 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
25651 SEH (Structured Exception Handling) now.
25652 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
25653 (__gnat_initialize for ppc-vxworks): Adjust comments and the
25654 preprocessor condition protecting the call to the extra eh setup
25655 subprogram, which is only available for the ppc target.
25656 (__gnat_clear_exception_count): replaced reference to
25657 variable taskIdCurrent by call to taskIdSelf(), cleaner.
25659 * seh_init.c: New file.
25661 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
25662 (GNATBIND_OBJS): Idem.
25664 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
25665 routine takes a new parameter (a pointer to the exception registration
25666 for the SEH (Structured Exception Handling) support.
25668 * raise.h: (__gnat_install_SEH_handler): New prototype.
25669 Update copyright notice.
25671 * s-tassta.adb (Task_Wrapper): Declare the exception registration
25672 record and initialize it by calling __gnat_install_SEH_handler.
25674 2005-02-09 Vincent Celier <celier@adacore.com>
25676 * make.adb (Gnatmake): Do not fail when the main project has no object

25682 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
25683 [VMS]: Add translations for g-enblsp.adb.
25685 * s-asthan-vms.adb: Removed.
25686 * s-asthan-vms-alpha.adb: Added.
25688 2005-02-09 Pascal Obry <obry@adacore.com>
25690 * Makefile.in (LIBGNAT_SRCS): Add seh_init.c.
25691 (LIBGNAT_OBJS): Add seh_init.o.
25693 2005-02-09 Arnaud Charlet <charlet@adacore.com>
25696 * Makefile.in: Link all gnat tools with -static-libgcc, since
25697 -shared-libgcc is now used by default on some systems (e.g. linux with
25699 Remove references to Makefile.prolog/generic, no longer used.
25701 2005-02-09 Vincent Celier <celier@adacore.com>
25703 * prj-makr.adb (Process_Directory): Put file name in canonical case
25704 before matching against the patterns.
25705 If gnatname has been invoked as <prefix>-gnatname
25706 then invoke the compiler as <prefix>-gcc, not just "gcc".
25708 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25710 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
25711 with expansion disabled. The actual subtype is needed among other
25712 places when the selected component appears in the context of a loop
25713 bound, and denotes a packed array.
25714 (Operator_Check): Always use the first subtype in the
25715 error message, to avoid the appearance of internal base types.
25716 (Transform_Object_Operation): Copy each actual in full
25717 to the parameter associations of the constructed call, rather than
25718 using the shallow copy mechanism of New_Copy_List. This ensures that
25719 the chaining of named associations is done properly.
25720 (Complete_Object_Operation): Rewrite node, rather than
25721 replacing it, so that we can trace back to the original selected
25724 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
25725 and calls that use object notation, if the called function is not
25726 declared in a withed unit, place the elaboration constraint on the
25727 unit in the context that makes the function accessible.
25728 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
25729 imposes an elaboration constraint between two packages.
25731 2005-02-09 Ed Schonberg <schonberg@adacore.com>
25733 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
25734 views of a private type after handling its private dependents, to
25735 maintain proper stack discipline between entry and exit from the
25738 2005-02-09 Cyrille Comar <comar@adacore.com>
25740 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

25745 * s-tporft.adb (Register_Foreign_Thread): Initialize Task_Image[_Len]
25746 fields for foreign threads.

25751 recursion warnings when compiled with -gnatdm.
25753 2005-02-09 Robert Dewar <dewar@adacore.com>
25755 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
25756 Slight fix to documentation of -gnaty with no parameters
25758 * xr_tabls.ads: Add ??? comment for missing overall comment
25760 * xsinfo.adb: Make default file name be sinfo.h, since this is what
25761 we now use by default.
25763 * xsnames.adb: Adjust end of file test to look for five space followed
25764 by '#' instead of six spaces. The format of xsnames.adb was modified
25765 in the last update.
25767 * a-numeri.ads: Add reference to AI-388 for greek letter pi
25770 * clean.adb: Minor reformatting.
25772 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
25773 gnatname.adb: Minor reformatting
25774 Add 2005 to copyright output when utility is run
25776 * csets.adb: Eliminate obsolete comment
25778 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
25781 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
25783 2005-02-09 Sergey Rybin <rybin@adacore.com>
25785 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
25786 the difference between compact and incompact layout and add the record
25787 representation clause to the example illustrating different layouts.
25788 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
25789 component clauses").
25791 2005-02-09 Florian Villoing <villoing@adacore.com>
25793 * gnat_ugn.texi: Fix typos.
25794 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
25796 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
25797 in the generated documentation.
25799 2005-02-09 Arnaud Charlet <charlet@adacore.com>
25801 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

25841 * exp_util.ads: Minor correction in comment.
25843 2005-02-09 Arnaud Charlet <charlet@adacore.com>
25845 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
25846 since this procedure is now too complex to be worth inlining.
25848 2005-02-09 Richard Henderson <rth@redhat.com>
25850 * utils.c (gnat_define_builtin): Remove.
25851 (gnat_install_builtins): Use build_common_builtin_nodes.

26091 this can be decided statically.
26093 2005-01-03 Olivier Hainque <hainque@adacore.com>
26095 * decl.c (compatible_signatures_p): New function. The intended purpose
26096 is to check if two function signatures for a call-site and a callee are

26628 (Remove_Next_Debug): Same fix
26630 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
26631 maintain back pointers now, though we did not used to, and comments
26633 (Prepend): Remove pragma Inline.
26634 (Remove_Next): Same cleanup
26636 2004-12-07 Thomas Quinot <quinot@adacore.com>
26638 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
26639 used to record an implicit dereference as a read operation on its
26640 prefix when operating under -gnatc. Necessary to avoid spurious
26641 'variable assigned but never read' warnings in that mode.
26642 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
26643 is a non-overloaded implicit dereference, call the above subprogram to
26644 ensure proper recording of references.
26646 2004-12-07 Gary Dismukes <dismukes@adacore.com>
26648 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
26649 to be resolved later as part of Analyze_Iteration_Scheme's call to
26652 2004-12-07 Ed Schonberg <schonberg@adacore.com>
26654 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

26664 * g-socket.ads (Get_Host_By_Address, Get_Host_By_Name): Clarify
26665 documentation of the behaviour of these functions when passed an IP
26666 address that has no record in the system hosts database and no reverse

26686 2004-12-07 Vincent Celier <celier@adacore.com>
26687 Sergey Rybin <rybin@adacore.com>
26689 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
26690 Files" with the new tool and package names.
26691 Reformatting to suppress most of the warnings for line too long
26692 Document the new section "Project Search Path:" in the output of
26694 Add gnatmetric section
26696 2004-12-07 Vincent Celier <celier@adacore.com>
26698 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
26699 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
26700 and -eit to -ept. Added qualifier
26701 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
26703 2004-11-27 Andreas Schwab <schwab@suse.de>
26705 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
26707 2004-11-25 Arnaud Charlet <charlet@adacore.com>
26709 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
26710 internal implementation unit GNAT.Sockets.Thin,
26711 as their usage for sockets is non-portable (using the read and write
26712 functions from the system runtime library is fine on UNIX but won't
26713 work under Windows).
26715 * mingw32.h: Update copyright notice.
26717 2004-11-25 Arnaud Charlet <charlet@adacore.com>
26719 * ada-tree.h: Minor reformatting of previous change to avoid lines
26720 longer than 79 characters.

26748 Add also a cast to kill another warning.
26749 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags

26753 (__gnat_dup2): New function.
26754 (__gnat_is_symbolic_link): Enable the effective body of this
26755 function when __APPLE__ is defined.
26757 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
26760 2004-11-18 Olivier Hainque <hainque@adacore.com>
26762 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
26763 address of which may be used to represent "others" and "all others"
26764 choices in exception tables, instead of the current harcoded
26765 (void *)0 and (void *)1.
26766 (Setup_Exception): Do nothing in the GNAT SJLJ case.
26768 * gigi.h (others_decl, all_others_decl): New decls representing the
26769 new Others_Value and All_Others_Value objects.
26770 (struct attrib): Rename "arg" component as "args", since GCC expects a
26771 list of arguments in there.
26773 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
26774 corresponding objects exported by a-exexpr, instead of hardcoded dummy
26777 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
26778 others_decl and all_others_decl instead of hardcoded dummy addresses
26779 to represent "others" and "all others" choices, which is cleaner and
26780 more flexible with respect to the possible eh pointer encoding policies.
26782 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
26783 (process_attributes): Account for the naming change of the "args"
26784 attribute list entry component.
26786 * decl.c (build_attr_list): Rename into prepend_attributes to allow
26787 cumulating attributes for different entities into a single list.
26788 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
26789 attributes for the current entity and propagate first subtype
26790 attributes to other subtypes.
26791 <E_Procedure>: Attribute arguments are attr->args and not
26792 attr->arg any more.
26793 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
26794 argument provided, as this is what GCC expects. Use NULL_TREE instead
26797 2004-11-18 Robert Dewar <dewar@adacore.com>
26799 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
26800 Minor reformatting througout (including new function specs)
26801 Add ??? comments asking for clarification.
26803 2004-11-18 Thomas Quinot <quinot@adacore.com>
26805 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
26806 incomplete duplicate implementation of this subprogram from butil.
26808 2004-11-18 Thomas Quinot <quinot@adacore.com>

26814 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
26815 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
26817 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
26819 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
26821 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
26822 distribution subprogram identifiers that are either subprogram numbers

26825 string distribution identifiers assigned to a given subprogram.
26826 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
26827 (Add_RAS_Dereference_TSS): Add comments.
26828 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
26829 is not referenced yet because it will be used by the PolyORB DSA
26831 (Insert_Partition_Check): Remove fossile code.
26832 (First_RCI_Subprogram_Id): Document this constant.
26833 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
26835 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
26836 replaced with calls to Get_Library_Unit_Name_String. Previously there
26837 were several instances of the same code in different locations in the
26838 compiler; this checkin completes the replacement of all of these
26839 instances with calls to a common subprogram.
26840 Minor reformatting.
26842 * sem_dist.adb: Remove comment noting that RPC receiver generation
26843 should be disabled for RACWs that implement RASs.
26844 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.

26849 (Note_Possible_Modification): Generate a reference only
26850 if the context comes from source.
26852 * snames.ads (PCS_Names): New subtype corresponding to names of
26853 supported implementations of the Partition Communication Subsystem
26854 (PCS) (i.e. the runtime library support modules for the distributed

26868 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
26869 (Expand_Pragma_Psect_Object): New procedure
26870 These procedures contain the revised and cleaned up processing for
26871 these two pragmas. This processing was formerly in Sem_Prag, but
26872 is more appropriately moved here. The cleanup involves making sure
26873 that the pragmas are properly attached to the tree, and that no
26874 nodes are improperly shared.
26876 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
26877 pragmas to Exp_Prag, which is more appropriate.
26878 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
26879 check for duplicates Remove use of Is_Psected flag, no longer needed.
26880 Use new Make_String_Literal function with string.
26882 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
26883 that are functions return universal values, that have to be converted
26884 to the context type.
26885 Use new Make_String_Literal function with string.
26886 (Get_Stream_Convert_Pragma): New function, replaces the use of
26887 Get_Rep_Pragma, which had to be kludged to work in this case.
26889 * freeze.adb: Use new Has_Rep_Pragma function
26891 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
26892 function with string.
26893 Use new Has_Rep_Pragma function.
26895 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
26898 2004-11-18 Robert Dewar <dewar@adacore.com>
26900 * errout.ads, errout.adb: (First_Sloc): New function
26902 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
26903 check (-gnatyx) instead of being included as a redundant construct
26906 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
26907 Style_Check_Order_Subprograms.
26909 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
26910 stylesw.adb: Add Style_Check_Xtra_Parens
26912 * usage.adb: Add line for -gnatyx (check extra parens)
26914 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
26916 2004-11-18 Ed Schonberg <schonberg@adacore.com>
26917 Robert Dewar <dewar@adacore.com>
26919 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
26920 discriminant of a constrained subtype, analyze the copy of the
26921 corresponding constraint, because in some cases it may be only
26922 partially analyzed.
26923 Removes long-lived ??? comments.
26925 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
26926 handled controlled or secondary-stack expressions within the
26927 iteration_scheme of a loop.
26929 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
26930 bounds that may contain functions calls, to prevent memory leaks when
26931 the bound contains a call to a function that uses the secondary stack.
26932 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
26933 generate temporaries for loop bounds that might contain function calls
26934 that require secondary stack and/or finalization actions.
26936 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
26937 selected component and the selector is overloadable (not just a
26938 function) treat as function call, Analyze_Call will disambiguate if
26940 (Analyze_Selected_Component): Do not generate an actual subtype for the
26941 selected component if expansion is disabled. The actual subtype is only
26942 needed for constraint checks.
26943 (Analyze_Allocator): If restriction No_Streams is set, then do
26944 not permit objects to be declared of a stream type, or of a
26945 composite type containing a stream.
26947 * restrict.ads: Remove the a-stream entry from Unit_Array, since
26948 No_Streams no longer prohibits with'ing this package.
26950 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
26951 discriminants, but the parent base has unknown discriminants, there is
26952 no discriminant constraint to inherit. Such a discrepancy can arise
26953 when the actual for a formal type with unknown discriminants is a
26954 similar private type whose full view has discriminants.
26955 (Analyze_Object_Declaration): If restriction No_Streams is set, then
26956 do not permit objects to be declared of a stream type, or of a
26957 composite type containing a stream.
26959 2004-11-18 Ed Schonberg <schonberg@adacore.com>
26961 * exp_dbug.ads: Update documentation to reflect simpler encoding for
26962 protected operations.
26964 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
26965 generated name, it complicates decoding in gdb and hinders debugging
26966 of protected operations.
26967 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
26968 flag for the protected entry barrier function.
26969 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info

26976 * Makefile.in: Inform the value of the variable GMEM_LIB in the
26977 Darwin-specific section.
26979 * lang-specs.h: Change the placement of the %1 marker.
26980 Works around the fact that gcc adds -fPIC by default under Darwin.
26982 2004-11-18 Ed Schonberg <schonberg@adacore.com>
26984 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
26985 type of the object with the packed array type, set the Analyzed flag
26986 on the object if it is an entity or simple indexed component, to avoid
26987 spurious type errors.
26989 2004-11-18 Gary Dismukes <dismukes@adacore.com>
26991 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
26992 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
26993 separate line from the version message.
26995 2004-11-18 Ed Falis <falis@adacore.com>
26997 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
26999 (init_float): Eliminate initialization of floating point status for
27000 AE653. The instructions have no effect for vThreads.
27002 2004-11-18 Vincent Celier <celier@adacore.com>
27004 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
27005 gnatbind is invoked with -shared.
27007 2004-11-18 Jose Ruiz <ruiz@adacore.com>
27009 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
27010 for Detect_Blocking which is redundant with the check done within the
27011 procedure Protected_Single_Entry_Call.
27012 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
27013 Detect_Blocking which is redundant with the check done within the
27014 procedure Protected_Single_Entry_Call.
27016 2004-11-18 Vincent Celier <celier@adacore.com>
27018 * makegpr.adb (Compile): Put the compiling switches (in package
27019 Compiler and on the command line) immediately after "-c", instead of
27020 at the end of the command line invocation of the compiler, when
27021 compiling a non-Ada file.
27022 (Build_Global_Archive): When there is no need to rebuild the archive,
27023 set Global_Archive_Exists, so that the archive is passed to the linker
27026 2004-11-18 Robert Dewar <dewar@adacore.com>
27027 Sergey Rybin <rybin@adacore.com>
27030 Remove extra paren check from list of checks for redundant constructs
27031 Add documentation of new -gnatyx style check (check extra parens)
27032 Remove paragraph about gnatelim debug options.
27034 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
27035 objects rather than forbidding dependencies on the package Ada.Streams.
27037 * sinfo.ads: Add ??? note that we should document pragmas passed to
27040 * g-expect.ads: Fix a few typos in the comments.
27042 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
27044 * misc.c (gnat_handle_option): Use %< and %> for quoting in
27047 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
27049 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
27051 2004-11-07 Andreas Schwab <schwab@suse.de>
27053 * Makefile.in (install-gnatlib): Remove spurious hyphen.
27055 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
27058 * Makefile.in (darwin): Set soext to .dylib.
27060 2004-10-26 Vincent Celier <celier@gnat.com>
27061 Thomas Quinot <quinot@act-europe.fr>
27063 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
27064 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
27065 there is no use of GNAT.Sockets.Constants.
27066 Remove remaining pragma Import for C_Write
27067 Remove C_Read and C_Write from internal implementation unit
27068 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
27069 the read and write functions from the system runtime library is fine
27070 on UNIX but won't work under Windows).
27072 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
27073 (Check_Selector): Use C_Recv instead of C_Read.
27074 Selectors are the GNAT.Sockets abstraction to perform a select()
27075 call on a set of descriptors. To allow abortion of an ongoing
27076 select operation, some data is written to a dedicated socket that
27077 is always monitored.
27078 Under Windows, the write and read library functions cannot operate
27079 on sockets, so we need to use send and recv instead, which is portable
27080 across all supported platforms.
27082 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
27083 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
27084 (using the read and write functions from the system runtime library is
27085 fine on UNIX but won't work under Windows).

27093 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
27094 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
27097 * Makefile.in: Add support for building shared libraries under Darwin.
27098 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
27099 the low level EH init subprogram to be called from __gnat_initialize.
27101 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
27102 indicates which options to pass to the archive indexer.
27104 * mlib-utl.adb: Add support for calling ranlib with additional
27105 options. This is needed for instance under Mac OS X.
27106 (Ranlib_Options): New global variable, used to store the potential
27107 options to pass to ranlib.
27108 (Ar): Use Ranlib_Options when spawning ranlib.

27111 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
27113 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
27114 instead of 8K, to reflect the real potential needs for stack-checking
27117 2004-10-26 Pascal Obry <obry@gnat.com>
27119 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
27121 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
27122 Windows only the initial thread stack size can be set so it is good to
27123 start we a low stack size.
27124 The OS will adjust the size as needed.
27126 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
27127 Nicolas Setton <setton@act-europe.fr>
27129 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
27130 "__unix__" instead of "unix".
27131 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
27132 sections were just mistakenly ignored. The former is
27133 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
27134 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
27135 of hpux. This prevents an unwanted definition of the symbol
27136 convert_addresses in adaint.o.
27138 2004-10-26 Gary Dismukes <dismukes@gnat.com>
27140 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
27141 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
27143 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27145 * a-filico.ads, a-filico.adb: fix incorrect header.
27147 2004-10-26 Javier Miranda <miranda@gnat.com>
27149 * a-ststio.ads: Fix typo in identifier
27151 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27153 * sem_ch4.adb: Minor reformatting.
27155 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27157 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
27158 enabled, check the result of unary and binary operations when the
27159 expression is the right-hand side of an assignment.
27161 2004-10-26 Vincent Celier <celier@gnat.com>
27163 * clean.adb (Delete): Do not output warnings when in quiet output and
27164 not in verbose mode.
27165 (Force_Deletions): New Boolean flag, defaulted to False
27166 (Delete): Only delete a file if it is writable, and when
27167 Force_Deletions is True.
27168 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
27169 (Usage): Line for new switch -f
27170 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
27173 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
27175 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
27176 JM type only if its size matches that of the wrapper. When a size is
27177 prescribed and the field is not aliased, remove the wrapper of a JM
27178 type only if the size is not greater than that of the packed array.
27179 (gnat_to_gnu_entity): Change the extension of packed array wrappers
27182 2004-10-26 Geert Bosch <bosch@gnat.com>
27184 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
27185 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
27186 (Pred): Implement in terms of Succ.
27188 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27190 * exp_aggr.adb (Safe_Component): An aggregate component that is an
27191 unchecked conversion is safe for in-place use if the expression of the
27192 conversion is safe.
27193 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
27194 be expandable in place even if the aggregate does not come from source.
27195 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
27196 designated object of an allocator in place, rather than building it
27197 first on the stack. The previous scheme forces a full copy of the array,
27198 and may be altogether unsusable if the size of the array is too large
27199 for stack allocation.
27201 2004-10-26 Robert Dewar <dewar@gnat.com>
27203 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
27204 compares if the component is atomic.
27206 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
27207 array assignment if the component type is atomic.
27209 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27210 Eric Botcazou <ebotcazou@act-europe.fr>
27212 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
27213 is aliased and is a by_reference type, do not pass by copy.
27214 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
27215 detect whether the call is in the right side of an assignment or
27216 the expression of an object declaration. Recurse on component
27217 association within aggregates.
27218 Call it in the condition that determines whether the temporary is
27219 necessary for correct stack-checking.
27221 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27223 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
27224 RACW_Type, used in the PolyORB version.
27225 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
27226 version and the GARLIC version.
27228 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
27229 Rename RCI_Info to RCI_Locator for better consistency between the
27230 GARLIC and PolyORB versions of the distributed systems annex.
27231 (DSA_Implementation_Name): This enumeration lists the possible
27232 implementations of the Partition Communication Subsystem for the
27233 Distributed Systems Annex (DSA). The three available implementations
27234 are the dummy stub implementation (No_DSA), and two versions based on
27235 two different distribution runtime libraries: GARLIC and PolyORB. Both
27236 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
27238 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
27241 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
27242 between the GARLIC and PolyORB versions of the distributed systems
27244 Remove RE_Unbounded_Reclaim_Pool since it is unused.
27246 2004-10-26 Gary Dismukes <dismukes@gnat.com>
27248 * gnat1drv.adb: Suppress calling the back end when
27249 Frontend_Layout_On_Target is true.
27251 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27253 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
27254 Set_Read_Only): New subprograms.
27255 These new routines allow the user to set or unset the Owner execute
27256 and Owner write permission flags on a file.
27258 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
27259 GNAT.OS_Lib.Set_Executable instead of rolling our own.
27261 2004-10-26 Matthew Gingell <gingell@gnat.com>
27263 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
27265 2004-10-26 Pascal Obry <obry@gnat.com>
27267 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
27268 memory before the faulting page we properly test the process read
27269 access for this address using appropriate Win32 routine.
27270 (HPUX sections): guard with "__hpux__" instead of "hpux".
27272 2004-10-26 Robert Dewar <dewar@gnat.com>
27274 * lib-xref.adb (Generate_Reference): Don't complain about reference to
27275 entry parameter if pragma Unreferenced set, since we do not properly
27276 handle the case of multiple parameters.
27278 2004-10-26 Vincent Celier <celier@gnat.com>
27280 * prj-env.adb: (Contains_ALI_Files): New Boolean function
27281 (Ada_Objects_Path.Add): For a library project, add to the object path
27282 the library directory only if there is no object directory or if the
27283 library directory contains ALI files.
27284 (Set_Ada_Paths.Add.Recursive_Add): Ditto
27286 2004-10-26 Vincent Celier <celier@gnat.com>
27288 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
27289 extension of library projects.
27291 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
27292 path defaults to ".:<prefix>/lib/gnat".
27293 (Parse): For an extending all project, allow direct import of a project
27294 that is virtually extended.
27296 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
27297 the specified name is directly imported, return its ID. Otherwise, if
27298 an extension of this project is imported, return the ID of the
27301 2004-10-26 Robert Dewar <dewar@gnat.com>
27303 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
27304 (Sub3): New procedure, used by Scaled_Divide
27305 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
27306 correct more than one instance of failure to propagate carries
27308 (Double_Divide): Handle overflow case of largest negative number
27309 divided by minus one.
27311 * s-arit64.ads (Double_Divide): Document that overflow can occur in
27312 the case of a quotient value out of range.
27315 2004-10-26 Robert Dewar <dewar@gnat.com>
27317 * s-bitops.adb (Bit_Eq): Remove redundant check.
27319 * s-bitops.ads: Minor comment updates
27320 Change some occurrences of Address to System.Address
27322 * s-carsi8.ads: Fix minor cut-and-paste error in comments
27324 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27326 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
27327 accessibility check to prefix that is a protected operation.
27329 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27331 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
27332 empty, post message on stub.
27334 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27335 Javier Miranda <miranda@gnat.com>
27337 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
27338 current instance appears within a unit that is directly in the context
27340 Used to determine whether the body of the instance should be analyzed
27341 immediately after its spec, to make its subprogram bodies available
27342 for front-end inlining.
27343 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
27344 constraint is not allowed on the component type (AARM 12.5.3(3))
27346 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27348 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
27349 'Storage_Pool): enhance, document & limit detection of non-sharable
27352 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
27354 * s-pooglo.ads: Add more documentation now that this pool is properly
27357 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27359 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
27360 or protected type with discriminants, do not constrain the
27361 corresponding record type if the subtype declaration has no
27362 discriminant constraints. This can be the case in source code, or in
27363 the subtype declaration created to rename an actual type within an
27366 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27368 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
27369 different kind of stub (possibly wrong name for file), do not check
27371 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
27372 includes call to some function that returns an unconstrained type, do
27375 2004-10-26 Ed Schonberg <schonberg@gnat.com>
27377 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
27378 appear in the code for the main unit. Dependencies among units in the
27379 context of the main unit are established when those other units are
27380 compiled. Otherwise spurious elaboration constraints can generate
27381 incorrect elaboration circularities.
27383 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
27384 Ed Schonberg <schonberg@gnat.com>
27386 * sem_util.adb (Is_Aliased_View): Defend against the case where this
27387 subprogram is called with a parameter that is not an object name. This
27388 situation arises for some cases of illegal code, which is diagnosed
27389 later, and in this case it is wrong to call Is_Aliased, as that might
27390 cause a compiler crash.
27391 (Explain_Limited_Type): Refine previous fix to include
27392 inherited components of derived types, to provide complete information.
27394 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
27395 is the prival for a protected object.
27396 It is necessary to mark this entity as a variable, in addition to
27397 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
27398 modified to avoid checking the Aliased flag on entities that are not
27399 objects. (Checking that flag for non-objects is erroneous and could
27400 lead to a compiler crash).
27402 2004-10-26 Robert Dewar <dewar@gnat.com>
27404 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
27405 X_Frac = 0.5, then we know that the number X must be positive.
27406 (Succ): Remove the same redundant test, and also fix the primary test
27407 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
27409 (Decompose): Add fuller comments to spec
27411 2004-10-26 Pascal Obry <obry@gnat.com>
27413 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
27414 validity (process must have read access). Set to 0 in all other cases.
27415 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
27416 violation on Win32.
27417 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
27418 segmentation violation.
27420 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
27422 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
27423 whose type is a constructed subtype of an aliased object with an
27424 unconstrained nominal subtype, convert the actual to the constructed
27425 subtype before taking its address.
27427 2004-10-26 Vincent Celier <celier@gnat.com>
27429 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
27430 (Is_Path_Name_Case_Sensitive): New function
27432 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
27433 (Base_Name, Simple_Name, Current_Directory, Compose,
27434 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
27437 2004-10-26 Cyrille Comar <comar@act-europe.fr>
27438 Vasiliy Fofanov <fofanov@act-europe.fr>
27439 Vincent Celier <celier@gnat.com>
27441 * gnat_ugn.texi: Generalize "finding memory problems" section into a
27442 "memory management issues" section and document some of the useful
27443 memory pools provided as part of the GNAT library.
27444 Remove "virtual" from declaration of A::method2 in
27445 the simple example of Ada/C++ mixed system.
27446 Library Projects may be virtually extended: their virtual extensions
27447 are not Library Projects.
27448 Added section on extending project hierarchies.
27450 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
27452 * adaint.c (__gnat_get_libraries_from_registry): Cast value
27454 (__gnat_portable_spawn): Remove const.
27456 * mingw32.h (MAXPATHLEN): Check for previous definition.
27458 2004-10-17 Matthias Klose <doko@debian.org>
27460 * gnatvsn.ads: Set gnat library version to 4.0.
27462 2004-10-05 Vincent Celier <celier@gnat.com>
27464 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
27466 2004-10-04 Laurent Guerby <laurent@guerby.net>
27469 * Makefile.in: Define and use RANLIB_FLAGS.
27471 2004-10-04 Pascal Obry <obry@gnat.com>
27473 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
27474 other x86 platforms).
27476 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
27478 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
27479 in general and triggers stack alignment adjustment for thread entry
27480 points on targets where this is necessary.
27482 2004-10-04 Bernard Banner <banner@gnat.com>
27485 * Makefile.in: Add section for powerpc linux
27486 Add variant i-vxwork-x86.ads
27488 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
27490 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
27492 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
27493 table registration calls when need be. Ensures no reference to the crt
27494 ctors symbol are issued in the SJLJ case, which avoids possible
27495 undefined symbol errors in the case of modules to be statically linked
27498 2004-10-04 Javier Miranda <miranda@gnat.com>
27500 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
27501 in-line the code corresponding to subprogram Analyze_Actuals. In
27502 addition, analyze the actuals only in case of subprogram call.
27504 2004-10-04 Ed Falis <falis@gnat.com>
27506 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
27508 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
27510 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
27511 in the documentation.
27513 2004-10-04 Robert Dewar <dewar@gnat.com>
27515 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
27517 (Analyze_Block_Statement): Add circuitry to detect following dead code
27518 (Check_Unreachable_Code): Handle case of block exit
27520 2004-10-04 Robert Dewar <dewar@gnat.com>
27522 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
27523 (XMatchD): Avoid warning for Logic_Error call
27525 2004-10-04 Robert Dewar <dewar@gnat.com>
27527 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
27528 consider expressions buried within a procedure actual to be an actual.
27529 This caused some blowups with uses of packed slices within a procedure
27532 2004-10-04 Robert Dewar <dewar@gnat.com>
27534 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
27535 longer need to be initialized to zero.
27536 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
27537 initialized to zero.
27539 * checks.adb (Expr_Known_Valid): Packed arrays are now always
27540 considered valid, even if the representation is modular. That's correct
27541 now that we no longer initialize packed modular arrays to zero.
27543 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
27544 suffixes. These are now documented as the only cases in which the
27545 debugger ignores outer records.
27546 Previously, the spec allowed arbitrary suffixes for this purpose.
27547 Change name of LJM to JM for packed array pad records
27548 Create separate section on packed array handling, and add a whole new
27549 set of comments to this section describing the situation with packed
27550 modular types and justification requirements depending on endianness.
27552 2004-10-04 Robert Dewar <dewar@gnat.com>
27554 * a-except.adb: Add a comment for last change
27556 * einfo.ads: Minor spelling correction in comment
27558 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
27560 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
27563 * sem_util.ads: Minor comment update
27565 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27567 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
27568 Inline_Always when in Configurable_Run_Time mode.
27570 * sem_prag.adb (Process_Convention): If entity is an inherited
27571 subprogram, apply convention to parent subprogram if in same scope.
27572 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
27573 when in Configurable_Run_Time mode.
27575 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27577 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
27578 class_wide type after component list has been inherited.
27580 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27582 * sem_ch12.adb (Check_Generic_Actuals): New predicate
27583 Denotes_Previous_Actual, to handle properly the case of a private
27584 actual that is also the component type of a subsequent array actual.
27585 The visibility status of the first actual is not affected when the
27586 second is installed.
27587 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
27588 make fully recursive the treatment of formals of packages declared
27590 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
27591 the above on exit from an instantiation.
27592 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
27593 current instantiation which is now complete.
27594 (Analyze_Package_Instantiation): No instantiated body is needed if the
27595 main unit is generic. Efficient, and avoid anomalies when a instance
27596 appears in a package accessed through rtsfind.
27598 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27600 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
27601 do not generate a declaration for a temporary if the call is part of a
27602 library-level instantiation.
27604 2004-10-04 Ed Schonberg <schonberg@gnat.com>
27606 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
27607 searching for a limited component to flag.
27609 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
27610 expansion of Input, to account for the fact that the implicit call
27611 generated by the attribute reference must freeze the user-defined
27612 stream subprogram. This is only relevant to 'Input, because it can
27613 appear in an object declaration, prior to the body of the subprogram.
27615 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
27616 expansion can proceed and further errors uncovered.
27617 (Minor clean up): Fix cases of using | instead of \ for continuation
27620 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27622 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.

27629 specified alignment before validating size.
27630 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
27631 stripped-down declaration for the type of the inner field when making
27634 * utils.c (finish_record_type): Do not compute the size in units
27635 incrementally. Instead compute it once for the rep clause case.
27636 Use gcc_assert and gcc_unreachable.
27638 2004-10-04 Vincent Celier <celier@gnat.com>
27640 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
27642 (Is_Valid_Path_Name): Take '/' as a directory separator.
27644 2004-10-04 Vincent Celier <celier@gnat.com>
27646 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
27647 (Extended_Project) only if Extended_Project is defined, to avoid
27649 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
27651 (Parse_Single_Project): Ditto.
27653 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
27654 Add_To_Project_Path for virtual projects.
27656 2004-10-04 Vincent Celier <celier@gnat.com>
27658 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

27661 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
27662 parameter Options_2.
27664 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
27665 Build_Dynamic_Library with an empty Options_2.
27667 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no

27671 directory separator, if any.
27672 (Gprmake): Do not allow mains on the command line for library projects.
27673 Do not attempt to link when the project is a library project.
27674 (Library_Opts): New table to store Library_Options.
27675 (Build_Library): If Library_Options is specified, pass these options
27676 when building a shared library.
27678 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
27680 * s-tposen.adb (Service_Entry): The object must be always unlocked at
27681 the end of this procedure now that the unlock operation was inserted
27684 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
27686 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
27687 corresponding to the Preallocated_Stacks flags in System.
27688 (Get_Target_Parameters): Including the processing for

27699 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
27700 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
27701 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
27702 used to signal whether the compiler creates the required stacks and
27703 descriptors for the different tasks (when True) or it is done by the
27704 underlying operating system at run time (when False).
27705 It is initially set to False in all targets.
27707 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
27708 if it is supported by the target.
27709 (Make_Task_Create_Call): Pass the stack address if it has been
27710 previously created. Otherwise pass a Null_Address.
27712 * snames.adb: Add _stack.
27714 * snames.ads: Add Name_uStack. Required to allow the expander to
27715 statically allocated task stacks.
27717 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
27718 Stack_Address argument.
27719 Check that its value is equal to Null_Address because this target does
27720 not support the static stack allocation.

27729 * exp_dist.adb: Split declaration of asynchronous flag out of
27730 Add_RACW_Read_Attribute.
27731 Minor reformatting for better alignment with PolyORB version.
27732 Store the entity for the asynchronous flag of an RACW, rather than the
27733 expression, in the asynchronous flags table. This will allow this flag
27734 to be used in other subprograms beside Add_RACW_Read_Attribute.
27736 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
27738 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

27742 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
27743 sockets constant MSG_NOSIGNAL (Linux-specific).
27744 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
27745 all Send operations.
27746 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
27747 from trigerring SIGPIPE.
27748 Rename components to avoid clash with Ada 2005 possible reserved
27750 (Check_Selector): When the select system call returns with an error
27751 condition, propagate Socket_Error to the caller.

27763 Change "pragma inline" to "pragma Inline" in information and error
27765 Minor reformatting.
27767 * freeze.adb (Check_Address_Clause): Remove previous change, not the
27768 right way of doing things after all.
27769 (Freeze_Entity): For object, set Is_Public for imported entities
27770 unless there is an address clause present.
27772 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
27774 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
27775 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
27776 ensures proper handling of types with rep clauses, which might have
27777 their TYPE_SIZE set already.
27779 2004-09-21 Robert Dewar <dewar@gnat.com>
27781 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
27782 packed array types in both little- and big-endian cases. This change
27783 ensures that we no longer count on the unused bits being initialized
27784 for such types (and in particular ensures that equality testing will
27785 only read the relevant bits).
27786 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
27787 These changes mean that we no longer need to initialize small packed
27789 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
27790 optimization to an LJM field as to its parent field.
27792 * ada-tree.h, trans.c, utils.c, utils2.c:
27793 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
27795 2004-09-20 Jan Hubicka <jh@suse.cz>
27797 * utils.c (gnat_finalize): Remove.
27798 (end_subprog_body): Directly call cgraph_finalize_function;
27799 do not lower the nested functions.
27801 2004-09-20 Robert Dewar <dewar@gnat.com>
27804 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
27805 if an address clause is present, since that means that the Import
27808 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
27810 * 5tsystem.ads: Removed, no longer used.
27812 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
27813 Zack Weinberg <zack@codesourcery.com>
27815 * ada-tree.def: Use tree_code_class enumeration constants
27816 instead of code letters.
27817 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
27818 Update for new tree-class enumeration constants.

27834 an existing directory.
27835 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
27836 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
27837 Convert the result to File_Size.
27839 * prj.ads: (Project_Error): New exception
27841 * prj-attr.adb: Except in procedure Initialize, Fail comes from
27842 Prj.Com, not from Osint.
27843 (Attrs, Package_Attributes): Tables moved to private part of spec
27844 (Add_Attribute, Add_Unknown_Package): Moved to new child package
27846 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
27847 Prj.Project_Error after call to Fail.
27848 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
27849 Fail. Check that package name is not already in use.
27851 * prj-attr.ads: Comment updates to indicate that all subprograms may be
27852 used by tools, not only by the project manager, and to indicate that
27853 exception Prj.Prj_Error may be raised in case of problem.
27854 (Add_Unknown_Package, Add_Attribute): Moved to new child package
27856 (Attrs, Package_Attributes): Table instantiations moved from the body to
27857 the private part to be accessible from Prj.Attr.PM body.
27859 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
27860 from new package Prj.Attr.PM.
27861 (Parse_Attribute_Declaration): Call Add_Attribute from new package
27864 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
27866 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
27867 instead of Elaboration_Checks).
27869 * a-calend.adb: Minor reformatting

27912 pragmas recognized by GNAT.
27914 * gnat_rm.texi: Document pragma Detect_Blocking.
27916 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
27917 raise Program_Error if called from a protected operation.
27919 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
27920 the protected action nesting level.
27921 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
27922 protected action nesting level.
27923 (Unlock): When pragma Detect_Blocking is active decrease the protected
27924 action nesting level.
27926 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
27927 Protected_Action_Nesting.
27929 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
27930 Common_ATCB record. It contains the dynamic level of protected action
27931 nesting for each task. It is needed for checking whether potentially
27932 blocking operations are called from protected operations.
27933 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
27934 Detect_Blocking is active or not in the partition.
27936 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
27937 raise Program_Error if called from a protected operation.

27946 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
27947 raise Program_Error if called from a protected operation, and increase
27948 the protected action nesting level.
27949 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
27950 Program_Error if called from a protected operation, and increase the
27951 protected action nesting level.

27957 the protected action nesting level.
27958 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
27959 Program_Error if called from a protected operation, and increase the
27960 protected action nesting level.

27966 protected action nesting level.
27968 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
27969 insertion of the statement raising Program_Error. The run time
27970 contains the required machinery for handling that.
27972 * sem_util.ads: Change comment associated to procedure
27973 Check_Potentially_Blocking_Operation.
27974 This procedure does not insert a call for raising the exception because
27975 that is currently done by the run time.
27977 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
27979 * init.c: Add the global variable __gl_detect_blocking that indicates
27980 whether pragma Detect_Blocking is active (1) or not (0). Needed for
27981 making the pragma available at run time.
27982 (__gnat_set_globals): Pass and update the detect_blocking parameter.
27984 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
27985 pragma Detect_Blocking is active.
27987 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
27989 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
27990 DB is found in the ali file. Any unit compiled with pragma
27991 Detect_Blocking active forces its effect in the whole partition.
27993 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
27994 Detect_Blocking is active and delay is called from a protected
27997 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
27998 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
27999 Detect_Blocking is active (0 otherwise).
28000 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
28001 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
28004 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
28006 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
28007 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
28010 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
28011 (Register_Receiving_Stub): Add Subp_Info formal parameter.
28012 Update API in placeholder implemetation of s-parint to reflect changes
28013 in distribution runtime library.
28015 * sem_ch3.adb (Expand_Derived_Record): Rename to
28016 Expand_Record_Extension.
28018 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
28019 primitive operations of potentially distributed object types that have
28020 non-controlling anonymous access formals.
28022 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
28024 New implementation of expansion for remote access-to-subprogram types,
28025 based on the RACW infrastructure.
28026 This version of sem_dist is compatible with PolyORB/DSA as well as
28029 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
28030 Asynchrronous that applies to a remote access-to-subprogram type, mark
28031 the underlying RACW type as asynchronous.
28033 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
28034 __gnat_using_gnu_linker to 1.
28036 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
28037 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
28038 GNAT.Perfect_Hash_Generators, and remove the empty
28039 GNAT.Perfect_Hash package.
28041 * atree.adb: Minor reformatting
28043 * exp_ch3.adb (Expand_Derived_Record): Rename to
28044 Expand_Record_Extension.
28045 (Build_Record_Init_Proc.Build_Assignment): The default expression in
28046 a component declaration must remain attached at that point in the
28047 tree so New_Copy_Tree copies it if the enclosing record type is derived.
28048 It is therefore necessary to take a copy of the expression when building
28049 the corresponding assignment statement in the init proc.
28050 As a side effect, in the case of a derived record type, we now see the
28051 original expression, without any rewriting that could have occurred
28052 during expansion of the ancestor type's init proc, and we do not need
28053 to go back to Original_Node.
28055 * exp_ch3.ads (Expand_Derived_Record): Rename to
28056 Expand_Record_Extension.
28058 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
28059 Returns the RACW type used to implement a remote access-to-subprogram
28061 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
28062 New subprograms. Used to create a proxy tagged object for a remote
28063 subprogram. The proxy object is used as the designated object
28064 for RAS values on the same partition (unless All_Calls_Remote applies).
28065 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
28066 System.Partition_Interface.Get_Unique_Remote_Pointer.
28067 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
28068 Renamed from Add_RAS_*_Attribute.
28069 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
28071 New implementation of expansion for remote access-to-subprogram types,
28072 based on the RACW infrastructure.
28074 * exp_dist.ads (Copy_Specification): Update comment to note that this
28075 function can copy the specification from either a subprogram
28076 specification or an access-to-subprogram type definition.
28078 2004-09-09 Ed Schonberg <schonberg@gnat.com>
28080 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
28081 in an instance, between an explicit subprogram an one inherited from a
28082 type derived from an actual.
28084 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
28085 add a polling call if the subprogram is to be inlined by the back-end,
28086 to avoid repeated calls with multiple inlinings.
28088 * checks.adb (Apply_Alignment_Check): If the expression in the address
28089 clause is a call whose name is not a static entity (e.g. a dispatching
28090 call), treat as dynamic.
28092 2004-09-09 Robert Dewar <dewar@gnat.com>
28094 * g-trasym.ads: Minor reformatting
28096 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except
28097 packed arrays, since unused bits are expected to be zero for a
28100 2004-09-09 Eric Botcazou <ebotcazou@act-europe.fr>
28102 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
28105 2004-09-09 Pascal Obry <obry@gnat.com>
28107 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
28108 enable map file generation. Add the right option to generate the map
28109 file if Map_File is set to True.
28111 * gnatdll.adb (Gen_Map_File): New variable.
28112 (Syntax): Add info about new -m (Map_File) option.

28336 for a global aliased object with a variable size and an unconstrained
28337 nominal subtype, pretend there is no initializer if the one we have is
28338 incomplete, and avoid referencing an inexistant component in there. The

28366 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
28367 discriminants that rename those of the parent, recover names of
28368 original discriminants for the constraint on the full view of the

28399 returning C.int, to avoid using a derived boolean type.
28401 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

28430 ignore overflows on low and high bounds of an index to also account for
28431 differences in signedness between sizetype and gnu_index_subtype.
28432 These are as legitimate as the ones caused by a lower TYPE_PRECISION

32349 complete assignment subtree which is now unnecessary, as the expansion
32350 of inlined call has been improved to preserve a consistent assignment
32351 tree. Note_Possible_Modification must be called only
32352 after checks have been applied, or else unnecessary checks will
32355 * sem_util.adb (Note_Possible_Modification): Reorganise the handling

32359 recorded as modifying the pointer);

32546 part has been scanned-out and it was present
32548 * par-ch3.adb, par-ch4.adb, par-ch6.adb: Give support to AI-231
32550 * sem_aggr.adb: (Check_Can_Never_Be_Null): New subprogram
32551 (Aggregate_Constraint_Checks): Generate conversion to the null-excluding
32552 type to force the corresponding run-time check
32553 (Resolve_Aggregate): Propagate the null-excluding attribute to the array
32555 (Resolve_Array_Aggregate): Carry out some static checks
32556 (Resolve_Record_Aggregate.Get_Value): Carry out some static check
32558 * sem_ch3.adb (Access_Definition): In Ada 0Y the Can_Never_Be_Null

32609 * sem_ch12.adb: Add comment for previous change
32611 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
32613 * osint.adb (Executable_Prefix): Set Exec_Name to the current
32614 executable name when not initialized. Otherwise, use its current value.
32616 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
32617 initialize it to another executable name than the current one. This
32618 allows to configure paths for an executable name (gnatmake) different
32619 from the current one (gnatdist).
32621 2004-03-29 Ed Schonberg <schonberg@gnat.com>
32623 * exp_ch6.adb (Expand_Call): A call to a function declared in the
32624 current unit cannot be inlined if it appears in the body of a withed
32625 unit, to avoid order of elaboration problems in gigi.
32627 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
32628 information for protected (wrapper) operation as well, to simplify gdb
32631 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
32632 protected body, indicate that the entity for the generated spec comes
32633 from source, to ensure that references are properly generated for it.
32634 (Build_Body_To_Inline): Do not inline a function that returns a
32637 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
32638 apply convention to homonyms that are declared explicitly.
32640 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
32641 that renames an equality operator and the operands are overloaded,
32642 resolve them with the declared formal types, before rewriting as an
32645 2004-03-29 GNAT Script <nobody@gnat.com>
32647 * Make-lang.in: Makefile automatically updated
32649 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
32651 * memtrack.adb: Log realloc calls, which are treated as free followed

32668 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
32670 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
32671 attribute reference does not denote a subtype, it can be any
32672 expression that has a classwide type, potentially after an implicit
32673 dereference. In particular, the prefix can be a view conversion for
32674 a classwide type (for which Is_Object_Reference holds), but it can
32675 also be a value conversion for an access-to-classwide type. In the
32676 latter case, there is an implicit dereference, and the original node
32677 for the prefix does not verify Is_Object_Reference.
32679 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
32680 conversion of a discriminant-dependent component of a mutable object
32683 2004-03-25 Ed Schonberg <schonberg@gnat.com>
32685 * freeze.adb (Freeze_Entity): When an inherited subprogram is
32686 inherited, has convention C, and has unconstrained array parameters,
32687 place the corresponding warning on the derived type declaration rather
32688 than the original subprogram.
32690 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
32691 indication on renaming declaration, if formal has a box and actual
32694 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
32695 determine whether to generate an implicit or explicit reference to
32696 the renamed entity.
32698 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
32699 subprogram renaming comes from a defaulted formal subprogram in an
32702 2004-03-25 Gary Dismukes <dismukes@gnat.com>
32704 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
32705 value expressions to ensure that calls within a component definition
32706 will be checked (since those are evaluated during the record type's
32709 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
32711 * s-tpobop.adb: Code clean up:
32712 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

32730 * gnatls.adb (Output_Unit): Add output of many flags (Dynamic_Elab,
32731 Has_RACW, Is_Generic, etc.)
32732 (Output_Object, Gnatls): Take into account ALI files not attached to
32735 2004-03-22 Vincent Celier <celier@gnat.com>
32737 * gprep.adb: Change all String_Access to Name_Id
32738 (Is_ASCII_Letter): new function
32739 (Double_File_Name_Buffer): New procedure
32740 (Preprocess_Infile_Name): New procedure
32741 (Process_Files): New procedure
32742 (Gnatprep): Check if output and input are existing directories.
32743 Call Process_Files to do the real job.
32745 2004-03-22 Robert Dewar <dewar@gnat.com>
32747 * prj-env.adb, prj-nmsc.ads, prj-proc.ads,
32748 s-stache.ads, s-stache.adb: Comment updates. Minor reformatting.
32750 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
32752 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
32753 case when the source contains only comments.
32755 2004-03-22 Ed Schonberg <schonberg@gnat.com>
32757 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
32758 declaration for a child subprogram body that acts as a spec, indicate
32759 that the entity in the declaration needs debugging information.
32761 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
32762 full view if the subtype is created for a constrained record component;
32763 gigi has enough information to construct the record, and there is no
32764 place in the tree for the declaration.
32766 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
32767 serial number for the dummy body that is built for analysis, to avoid
32768 inconsistencies in the generation of internal names when compiling
32771 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
32773 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
32776 2004-03-22 GNAT Script <nobody@gnat.com>

32795 2004-03-20 Joseph S. Myers <jsm@polyomino.org.uk>
32798 * gnat_ug.texi: Add info directory category and entry.
32799 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
32800 gnat_ug_wnt.texi: Regenerate.
32802 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
32804 * ada-tree.h: Update copyright notice.
32805 Minor reformatting.
32807 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
32809 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
32810 as regular exception objects and not as mere integers representing the
32811 condition code. The latter approach required some dynamics to mask off
32812 severity bits, which did not fit well into the GCC table based model.
32813 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
32814 exception data objects. We don't it and it would conflict with the other
32815 external symbol we have to generate for such exceptions.
32817 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
32818 the special code for VMS exceptions, since these are now represented
32819 as regular exceptions objects.
32821 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
32823 * decl.c (debug_no_type_hash): Remove.
32824 (gnat_to_gnu_entity, case E_Array_Type): Don't set and clear it.
32825 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
32827 2004-03-19 Laurent Guerby <laurent@guerby.net>
32829 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
32830 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
32832 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
32834 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
32835 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
32836 (TYPE_RM_SIZE_INT): Directly use type.values.
32837 (TREE_LOOP_ID): Clean up check.
32838 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
32839 TYPE_VALUES, not TYPE_FIELDS.
32840 * trans.c (convert_with_check): Delay access of bounds of basetype
32841 until sure is numeric.

32848 * 5ataprop.adb, 5ftaprop.adb, 5htaprop.adb, 5itaprop.adb, 5staprop.adb,
32849 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
32850 Specific.Set instead of direct call to e.g pthread_setspecific.
32852 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
32854 * adaint.c: Update comments.
32856 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
32857 GNATLIB_SHARED for FreeBSD.
32859 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
32861 * init.c [VxWorks]: Do not fix the stack size for the environment task.
32862 When needed (stack checking) the stack size is retrieved
32863 from the VxWorks kernel.
32865 * Makefile.in: Flag -nostdinc is required when building the run time
32866 for avoiding looking for files in the base compiler.
32867 Add the VxWorks specific version of the package body for
32868 System.Stack_checking.Operations (5zstchop.adb).
32870 * Make-lang.in: Add the object file for
32871 System.Stack_Checking.Operations.
32873 * Makefile.rtl: Add object file for the package
32874 System.Stack_Checking.Operations.
32876 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
32878 * s-stache.ads, s-stache.adb: Move the operations related to stack
32879 checking from this package to package System.Stack_Checking.Operations.
32880 This way, stack checking operations are only linked in the final
32881 executable when using the -fstack-check flag.
32883 2004-03-18 Doug Rupp <rupp@gnat.com>
32885 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
32888 * 5qsystem.ads, 5xcrtl.ads: New files.
32890 2004-03-18 Vincent Celier <celier@gnat.com>
32892 * prj.adb (Reset): Reset hash table Files_Htable
32894 * prj-env.adb (Source_Paths, Object_Paths): New tables.
32895 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
32896 the procedures Add_To_Path_File.
32897 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
32898 making sure that each directory is present only once and, for object
32899 dirs, when a directory already present is added, the duplicate is
32900 removed and the directory is always put as the last in the table.
32901 Write the path files at the end of these accumulations.
32903 * prj-nmsc.adb (Record_Source): Add source file name in hash table
32904 Files_Htable for all sources.
32906 * prj-proc.adb (Process): Remove restrictions between not directly
32907 related extending projects.
32909 2004-03-18 Emmanuel Briot <briot@act-europe.fr>

32915 parameter Trusted_Mode.
32917 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
32919 * scn.adb (Determine_License): Take into account a degenerated case
32920 when the source contains only comments.
32922 2004-03-18 Ed Schonberg <schonberg@gnat.com>
32924 * sem_warn.adb (Check_References): For a warning on a selected
32925 component that does not come from source, locate an uninitialized
32926 component of the record type to produce a more precise error message.
32928 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
32930 * 3zsoccon.ads: Fix multicast options.
32932 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
32935 2004-03-15 Robert Dewar <dewar@gnat.com>
32937 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
32938 pragma used for a private type.
32940 * lib-xref.adb (Generate_Reference): Do not generate warning if
32941 reference is in a different unit from the pragma Unreferenced.
32943 * 5vtpopde.adb: Minor reformatting
32944 Fix casing of To_Task_ID
32946 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
32947 flag if we have an unchecked conversion to an access type in the same
32950 2004-03-15 Geert Bosch <bosch@gnat.com>
32952 * a-ngcoty.adb (Modulus): In alternate formula for large real or
32953 imaginary parts, use Double precision throughout.
32955 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
32956 we want to be able to compile run-time with -gnata for testing, but
32957 this may also be instantiated in user code that is compiled with -gnata.
32959 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
32961 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
32962 codes. Having a separate type for this is useful to enforce consistency
32963 throughout the various run-time units.
32964 (Exception_Data): Use Exception_Code for Import_Code.
32966 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
32967 Natural and Integer in various places.
32968 (Register_VMS_Exception): Use Base_Code_In to compute the exception code
32969 with the severity bits masked off.
32970 (Register_VMS_Exception): Handle the additional exception data pointer
32973 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
32974 component, now reflected by an exported accessor.
32975 (is_handled_by): New routine to compute whether the propagated
32976 occurrence matches some handler choice specification. Extracted out of
32977 get_action_description_for, and expanded to take care of the VMS
32979 (get_action_description_for): Use is_handled_by instead of an explicit
32980 complex condition to decide if the current choice at hand catches the
32981 propagated occurrence.
32983 * raise.h (Exception_Code): New type for C.
32985 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
32986 System.Standard_Library.Exception_Code, to allow references from the
32987 pragma import/export expander.
32989 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
32990 New accessors to allow easy access to GNAT exception data
32992 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
32993 redundant Handled_By_Others component, helper for the personality
32994 routine which will now be able to call the appropriate exception data
32997 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
32998 component of Standard_Exception_Type to be the closest possible to
32999 Exception_Code in System.Standard_Library, that we cannot get at this
33000 point. Expand a ??? comment to notify that this type node should
33001 probably be rewritten later on.
33003 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
33004 registration call to include a pointer to the exception object in the
33007 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
33008 instead of int and explicit bitmasks.
33010 2004-03-15 Vincent Celier <celier@gnat.com>

34001 Don't make a bitfield if the field is to be addressable.
34002 Always set a size for the field if the record is packed, to ensure the
34003 checks for bitfield creation are triggered.
34004 (finish_record_type): During last pass over the fields, clear
34005 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

34464 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
34465 N_String_Literal node always references an E_String_Literal_Subtype
34466 entity. This may not be true in the future.
34467 (Possible_Bit_Aligned_Component): Move processing of
34468 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
34470 * exp_ch6.adb (Expand_Thread_Body): Pick up

34475 (Type_May_Have_Bit_Aligned_Components): New function.

34515 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
34516 ineffective elaborate all pragmas on non-visible packages (this
34517 happened when a renamed subprogram was called). Now the elaborate all
34518 always goes on the package containing the renaming rather than the one
34519 containing the renamed subprogram.
34521 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
34522 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

34583 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve

34626 pure, emit warning.
34627 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and

34739 to __gnat_map_signal, imported from init.c to support
34740 signal -> exception mappings that depend on the vxWorks version.
34743 Created and exported __gnat_map_signal to support signal -> exception
34744 mapping that is dependent on the VxWorks version.

34775 2003-12-11 Ed Schonberg <schonberg@gnat.com>
34777 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
34778 bounds of a loop, create a separate block in order to generate proper
34779 cleanup actions to prevent memory leaks.
34781 * sem_res.adb (Resolve_Call): After a call to
34782 Establish_Transient_Scope, the call may be rewritten and relocated, in
34783 which case no further processing is needed.

34798 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
34801 2003-12-08 Robert Dewar <dewar@gnat.com>
34803 * 7sintman.adb: Minor reformatting
34805 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
34806 standard linker options to get standard libraries linked. We now plan
34807 to provide dummy versions of these libraries to match the appropriate
34808 configurable run-time (e.g. if a library is not needed at all, provide
34809 a dummy empty library).
34811 * targparm.ads: Configurable_Run_Time mode no longer affects linker
34812 options (-L parameters and standard libraries). What we plan to do is
34813 to provide dummy libraries where the libraries are not required.
34815 * gnatbind.adb: Minor comment improvement
34817 2003-12-08 Javier Miranda <miranda@gnat.com>
34819 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
34820 aggregate in the parent. Otherwise constants with limited aggregates

34822 It is required to call the corresponding IP subprogram in case of
34823 default initialized components.
34824 (Gen_Assign): In case of default-initialized component, generate a
34825 call to the IP subprogram associated with the component.
34826 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
34827 of aggregate with default initialized components.
34828 (Has_Default_Init_Comps): Improve implementation to recursively check
34829 all the present expressions.
34831 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
34832 to indicate that the initialization call corresponds to a
34833 default-initialized component of an aggregate.
34834 In case of default initialized aggregate with tasks this parameter is
34835 used to generate a null string (this is just a workaround that must be
34836 improved later). In case of discriminants, this parameter is used to
34837 generate a selected component node that gives access to the discriminant
34840 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
34841 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
34842 allocated aggregates with default-initialized components.
34844 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
34845 the box notation is used in positional aggregates.

34887 Process nodes N_Comment.
34889 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
34890 without comments and there are some comments, set the flag
34891 Unkept_Comments to True.
34892 (Scan): If there are comments, set the flag Unkept_Comments to True and
34893 clear the comments.
34894 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
34895 (Next_End_Nodes: New table

34923 Comment_Id and set Token to Tok_Comment when scanning a comment.
34924 (Set_Comment_As_Token): New procedure
34926 * sinput-p.adb: Update Copyright notice
34927 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

34932 * sem_aggr.adb: Add dependence on Exp_Tss package
34933 Correct typo in comment
34934 (Resolve_Aggregate): In case of array aggregates set the estimated
34935 type of the aggregate before calling resolve. This is needed to know
34936 the name of the corresponding IP in case of limited array aggregates.
34937 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
34938 in case of default initialized array components.
34940 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

34960 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
34961 they are automatically generated by Make-lang.in and cause nothing but
34962 maintenance troubles.
34964 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
34966 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

34980 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
34981 to ensure that the kernel fills in the interrupted context structure
34982 before calling a signal handler, which is necessary to be able to
34983 unwind past it. Update the copyright notice.
34985 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
34987 * a-elchha.ads: New file.
34989 * a-elchha.adb: New default last chance handler. Contents taken from
34990 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.

35071 redundant inclusion of EXTRA_HIE_NONE_TARGET_PAIRS, which is always
35072 included in HIE_NONE_TARGET_PAIRS.
35074 2003-12-03 Ed Schonberg <schonberg@gnat.com>
35077 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
35078 is legal in an instance, because legality is cheched in the template.
35081 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
35082 appplied to an unchecked conversion of a formal parameter.
35085 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

35099 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
35100 so that the debugger can reliably access the value of the parameter,
35101 and therefore is able to display the exception name when an exception
35102 breakpoint is reached.
35104 2003-12-01 Thomas Quinot <quinot@act-europe.fr>
35106 * fmap.adb: Fix typo in warning message.

36441 Remove the test against being in No_Run_Time_Mode before generating a
36442 call to Register_Tag. It is redundant with the test against the
36443 availability of the function Register_Tag.

36455 no main is specified on the command line and attribute Mains is not
36456 empty, only build the Ada main. If there is no Ada main, just compile

36459 information, check that the source exists and, if it does, that the path
36460 is the actual path of a source of a project.

38650 (general) Add @./@: where approriate, and two spaces after the
38651 full stop at the end of a sentence. Use @samp markup when
38652 referring concrete lexical entities (keywords, attribute names
38653 etc.), and @syntax for ARM grammar elements. Use @r for English

38732 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
38733 need to force universal inlining for these cases.
38735 2001-12-19 Arnaud Charlet <charlet@gnat.com>
38737 * s-taprob.adb: Minor clean ups so that this unit can be used in

39038 2001-12-17 Laurent Pautet <pautet@gnat.com>
39041 Fix comment of Shutdown_Socket and Close_Socket. These functions
39042 should not fail silently because if they are called twice, this
39043 probably means that there is a race condition in the user program.
39044 Anyway, this behaviour is consistent with the rest of this unit.
39045 When an error occurs, an exception is raised with the error message
39046 as exception message.

40380 instead of the previous simple checksum algorithm.
40381 (Time_Stamp_Mismatch): use CRC_Match for comparison.
40382 (Set_Source_Table): idem.
40385 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
40386 instead of simple checksum.
40387 (CRC_Match): new function.
40388 (CRC_Error): new constant.
40390 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
40391 a CRC now and not a simple checksum. A CRC uses lower-case hex
40392 letters, fixes ambiguity in parsing.
40394 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
40395 is what this variable will store.
40397 * bcheck.adb: Change reference to chechsum in comments by CRC.
40398 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
40399 rename All_Checksum_Match to All_CRC_Match. Change due to API
40400 renaming since now GNAT does not use a simple checksum but a
40401 CRC using GNAT.CRC32.
40403 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
40404 now and not anymore a simple checksum.
40406 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
40409 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
40412 (Restore_Scan_State): rename Checksum to CRC.

40417 (Checksum): rename to CRC.
40418 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
40420 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
40421 GNAT.CRC32). Update copyright notice.
40423 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
40424 GNAT.CRC32). Update copyright notice.
40427 (Accumulate_Checksum): removed.
40428 (Update): new procedure. Add a wide-character into the CRC.
40431 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
40432 (Load_File): fix initialization of S (change Source_Checksum to
40435 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
40436 Source_CRC in S initialization.
40438 * sinput.adb (Source_Checksum): renamed to Source_CRC.
40440 * sinput.ads (Source_Checksum): renamed to Source_CRC.
40441 Update comments for the CRC.
40443 * types.adb (Hex): Use lowercase for the letter part.
40445 * types.ads (Get_Hex_String): Returns the hexadecimal representation
40446 for a word. This is currently used only for CRC. In previous version,
40447 the checksum was using a representation with all letter being
40448 upper-case. With the new implementation (using CRC) we do not remove
40449 the 32th bit of the CRC, so we can have an upper-case starting letter
40450 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
40451 It is ambigous since the CRC was optional and could be followed by
40452 options like EB, EE. So now this routines uses lower-case letter for
40453 the hexadecimal representation. Strange enough only lower case letters
40454 where checked in Scan_ALI (even if this was not a possible case).
40456 * gnatvsn.ads (Library_Version): changed to 3.15a.
40458 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
40461 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
40464 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
40465 Add 2001 to copyright notice
40466 (Accumulate_Checksum): Modify to use System.CRC32.
40468 * ali-util.ads: Redo changes of previous revision to continue to use
40469 the word Checksum. Add 2001 to copyright notice.
40471 * ali.adb: Undo some of previous changes, not needed.
40472 Keep the change for lower case letters in the checksum.
40474 * ali.ads: Undo previous change not needed.
40476 * bcheck.adb: Undo most of previous change, not needed.
40477 But do use Checksums_Match for checksum comparison.
40479 * gnatls.adb: Undo most of previous change, not needed.
40480 But do use Checksums_Match for comparing checksums.
40482 * lib-load.adb: Undo previous change, not needed.
40484 * lib-writ.adb: Undo previous change, not needed.
40486 * lib-writ.ads: Document that checksums use lower case,
40487 not upper case letters.

40491 * scans.ads: Undo previous change, not needed.
40493 * scn-nlit.adb: Undo previous changes, not needed.
40495 * scn-slit.adb: Undo previous change, not needed. Fix header format.
40498 (Accumulate_Checksum): Use System.CRC32.
40499 (Initialize_Checksum): New procedure.
40500 Remove other changes of previous revision.
40502 * sinput-p.adb: Undo previous change, not needed.
40504 * sinput.adb: Undo previous change, not needed.
40506 * sinput-l.adb: Undo previous change, not needed.
40508 * sinput.ads: Undo previous change, not needed. Keep only comment
40509 on new checksum algorithm
40511 * Makefile.in: Add s-crc32 as needed, remove g-crc32.
40512 Also remove a-tags and a-stream from GNAT sources.
40514 * ali.adb (Scan_ALI): fix typo introduce in latest check-in.
40516 * Makefile.in (GNATRTL_NONTASKING_OBJS): Add g-crc32.o.
