1655 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1656 Orig_Prev to Prev in the case where the actual is N_Function_Call or

3851 (Build_Discriminated_Subtype): Do not inherit representation clauses
3852 from parent type if subtype already carries them, because they are
3853 inherited earlier during derivation and already include those that may
3854 come from a partial view.

3893 through dispatching, never through static calls).
3894 (Collect_Interps): When only one interpretation has been found, set N's
3895 Entity and Etype to that interpretation, otherwise Entity and Etype may
3896 still refer to an interpretation that was ignored by Add_One_Interp,
3897 in which case would end up with being marked as not overloaded but with

7914 reference before the actual is resolved and expanded, to prevent
7915 spurious warnings on formals of enclosing protected operations.
7916 (Analyze_Overloaded_Selected_Component): If type of prefix if
7917 class-wide, use visible components of base type.

8023 clauses for inherited components of a type extension.
8024 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
8025 an overloadable item if it is a pragma that can apply to multiple
8026 overloadable entities (e.g. Inline) because a pragma cannot be on
8027 more than one chain at a time.

8157 subprogram body that acts as its own spec may not have a non-private
8158 WITH clause on a private sibling.
8159 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8160 child unit is a renaming, create an implicit with_clause on that
8161 parent, and not on the unit it renames, to prevent visibility errors

8208 of Related_Interface to Related_Type.
8209 (Record_Type_Declaration): Minor reordering of calls to decorate the

8265 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8266 Timed_Entry_Call): Analyze the triggering statement as the first step of
8267 the processing. If this is a dispatching select, postpone the analysis
8268 of all select statements until the Expander transforms the select. This

8270 replicated some of the select statements. In case the Expander is
8271 disabled, perform regular analysis.
8272 (Check_Triggering_Statement): New routine.
8273 (Analyze_Requeue): Exclude any interpretations that are not entries when
8274 checking overloaded names in a requeue. Also test type conformance for

8283 for the defaulted actual.
8285 2007-12-13 Geert Bosch <bosch@adacore.com>
8287 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

8312 latest Ada 2005 rules about renaming and 'Access of
8313 discriminant-dependent components.

8870 multiple inherited interfaces info. This information cannot be stored
8871 in Xref_Entity_Record, which only supports a single instance of Tref_*,

8890 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
8891 that handles use of 'Access and 'Unchecked_Access applied to

8899 (Freeze_Array_Type): For a packed array type, generate an initialization
8900 procedure if the type is public, to handle properly a client that
8901 specifies Normalize_Scalars.
8903 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
8905 * exp_ch9.adb (Actual_Index_Expression): When the expansion occurs

8937 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
8938 used by VxWorks targets to have access to task-specific data and be
8939 able to extract the stack boundaries for stack checking.
8940 Use system-vms-ia64.ads on ivms.
8942 * Make-lang.in: Update dependencies.
8944 * sysdep.c (__gnat_get_stack_info): Move to a standalone file
8947 2007-10-15 Vincent Celier <celier@adacore.com>

8963 Runtime_Library_Dir.
8965 * prj-part.adb (Parse_Single_Project): Do not check the name of the
8966 config project against the user project names.

8981 2007-10-15 Gary Dismukes <dismukes@adacore.com>
8983 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
8984 association for an access component, add an association with null as
8985 the expression. Remove testing for array subtypes and the setting in
8986 that case of Ctyp to the array component type, which prevented proper
8987 inclusion of an association for null-initialized arrays. Collapse
8988 condition that tests for array subtypes into just a test of
8989 Is_Partially_Initialized_Type (which already covers arrays anyway).
8991 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
8993 * sem_ch12.adb: Minor code reformatting.
8994 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to

9001 flag of derived concurrent types, taking into account the flag setting
9002 on the parent subtype and any new set of discriminants.
9004 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9006 * sem_ch4.adb: Minor code and comment reformatting.
9007 (Analyze_Allocator): When the designated type of an unconstrained
9008 allocator is a record with unknown discriminants or an array with
9009 unknown range bounds, emit a detailed error message depending on the
9010 compilation mode and whether the designated type is limited.

9133 2007-09-27 Eric Botcazou <ebotcazou@adacore.com>
9135 Mapped location support
9136 * back_end.adb (Call_Back_End): Pass information about source
9137 files instead of units to gigi.
9138 * gigi.h (struct File_Info_Type): New.
9139 (gigi): Rename and change type of number_units parameter, change
9140 type of file_info_ptr parameter.
9141 * trans.c (number_files): New global variable.
9142 (gigi): Rename and change type of number_units parameter, change
9143 type of file_info_ptr parameter.
9144 If mapped location support is enabled, create the isomorphic mapping
9145 between source files and line maps.
9146 (Sloc_to_locus): If mapped location support is enabled, translate
9147 source location into mapped location.
9148 (annotate_with_node): Rename into set_expr_location_from_node.

9174 * a-calend-vms.adb, a-calend.adb:
9175 Add a section on leap seconds control along with two entities used to
9176 enable and disable leap seconds support. The array Leap_Second_Times is
9177 now constant and contains hard time values pre-generated. Remove
9178 all elaboration code used to populate the table of leap seconds.
9181 Add entity Leap_Seconds_Support to the list of global run-time variables
9182 along with a comment on its usage and values.
9183 (Gen_Adainit_Ada): Add code to generate the declaration and import of
9184 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
9185 or one (enabled) depending on the presence of binder switch "-y".
9186 (Gen_Adainit_C): Add code to generate the declaration of external int
9187 __gl_leap_seconds_support. Set is value to zero (disabled) or one

9198 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
9200 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
9202 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
9203 function which can be called by the debugger to interrupt the tasks of
9204 an Ada application asynchronously, as needed on VxWorks.
9205 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
9207 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
9208 renamed from Stop_All_Tasks. Update comments.

9224 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
9226 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9229 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9231 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9234 * sem_dist.ads: Minor comment fix

9238 2007-09-26 Javier Miranda <miranda@adacore.com>
9239 Eric Botcazou <ebotcazou@adacore.com>
9242 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9243 indirection added to the HT_Link component of the TSD. This is required
9244 to statically allocate the TSD.
9247 Minor reordering of the declarations in the private part. Required to
9248 add a level of indirection to the contents of the TSD component HT_Link.
9249 This is required to statically allocate the TSD.
9251 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9252 Is_Statically_Allocated set from constant objects.
9253 Do not make exported constants created by the compiler volatile.
9254 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9257 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9258 before returning them.
9260 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9261 public part of the package.
9262 (Make_DT): Move HT_Link component out of the TSD record. For this
9263 purpose Make_DT now declares a separate object that stores the
9264 HT_Link value, and initializes the TSD component with the address
9265 of this new object. The addition of this level of indirection is
9266 required to statically allocate the TSD because the TSD cannot
9267 have variable components.
9268 (Expand_Interface_Conversion): Improve the expanded code.
9269 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9271 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9272 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9273 if we are building static dispatch tables then we must not generate
9274 extra code to register the primitive because the dispatch table will
9275 be built at the end of the library package; otherwise we notify that
9276 we cannot build the static dispatch table.
9278 2007-09-26 Robert Dewar <dewar@adacore.com>
9280 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9295 for thunks associated with interface types.
9297 * einfo.ads: Improve documentatation of Is_Internal
9298 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9299 associated with interface types.
9300 Extensive comment fixes regarding flags that appear in all entities. The
9301 documentation is now consistent for all such flags (there were a number
9302 of errors in the documentation in this regard).
9304 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9306 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9307 of these procedures are passed a function call that already has
9308 build-in-place actuals (testing new flag
9309 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9310 the case where processing continues.
9311 (Expand_Call): If the call is generated from a thunk body then we
9312 propagate the extra actuals associated with the accessibility
9313 level of the access type actuals.
9315 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9316 of each extra formal of a protected operation to reference the
9317 corresponding extra formal of the subprogram denoted by the
9318 operation's Protected_Body_Subprogram.
9320 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9321 N_Function_Call nodes.
9323 2007-09-26 Robert Dewar <dewar@adacore.com>
9325 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9327 * debug.adb: Add d.s flag.
9329 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9331 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9332 debug variable so that it won't be initialized when pragma
9333 Initialize_Scalars is in effect.
9335 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9337 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9338 initialization of a full view. This is moved to
9339 Analyze_Package_Specification.
9341 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9342 preelaborable initialization of a full view in entity loop.
9343 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9344 its child units are use-visible only if they are visible child units.
9346 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9347 whether an expression can be used within a type declaration that
9348 requires preelaborable init.
9349 (Check_Components): Replace inline code that does partial checking for
9350 preelaborable default expressions with call to
9351 Is_Preelaborable_Expression.
9352 (Has_Preelaborable_Initialization): In the case of a generic actual
9353 subtype, (that is, Is_Generic_Actual is True), return the result of
9354 applying Has_Preelaborable_Initialization to the generic actual's base
9357 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9359 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9360 call to Jan_1_Day _Of_Week to optimize its performance.
9361 (Is_Leap): Move the routine to the scope of Week_In_Year.
9362 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9363 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9364 avoids calling Time_Of and Split, thus making it more efficent.
9365 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9367 * g-calend.ads (Week_In_Year): Change comment to reflect new
9370 2007-09-26 Emmanuel Briot <briot@adacore.com>
9372 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9373 Command_Line): New types
9374 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9375 support for defining how switches can be grouped on a command line (as
9376 is the case for -gnatw... for GNAT), and how simple switches can be
9377 used as aliases for more complex switches (-gnatwa is same as
9379 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9380 (Start, Current_*): New subprograms
9381 Added support for parsing an array of strings in addition to the real
9383 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9384 be moved from the body to the private part of the spec.
9385 (*): All subprograms now have an extra parameter with default value to
9386 specify which parser should be used. For backward compatibility, it
9387 defaults to parsing the command line of the application. They were also
9388 modified to properly handle cases where each of the argument does not
9389 start at index 1 (which is always true for Ada.Command_Line, but not
9390 when processing any Argument_List).
9391 (Free): New subprogram
9392 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9393 Argument): New subprograms
9394 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9395 special characters like ':', '=',... are now handled in a single place,
9396 which makes the code more extensible eventually.
9397 (Getopt, Full_Switch): When the switch was returned as part of the
9398 special character '*', make sure it is prepended by the switch character
9399 ('-' in general), so that the application knows whether "foo" or "-foo"
9400 was specified on the command line.
9402 2007-09-26 Florian Villoing <villoing@adacore.com>
9404 * g-dirope.adb (Remove_Dir): In case we are removing directories
9405 recursively, make sure that if an exception is raised during the
9406 processing, the current working directory is reset to its initial
9407 value before propagating the exception.
9409 2007-09-26 Vincent Celier <celier@adacore.com>
9411 * gnatbind.adb: If there are several ALI files specified and there is
9412 a main program to bind, the first ALI is expected to contain the main
9413 subprogram and the names of the binder generated files will be derived
9414 from the first ALI file name.
9415 (Gnatbind): Fix insertion character in invocation of Error_Msg
9417 2007-09-26 Vincent Celier <celier@adacore.com>
9419 * gnatcmd.adb (Check_Files): Do not include sources that have been

9799 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9800 body for 'Output when the type is abstract (only the creation of the
9801 body for 'Input is excluded when the type is abstract).

9803 statement, so that False will be returned for TTS_Stream_Input if the
9804 associated tagged type is an abstract extension. Add comments for

9807 variable, insert init proc call only after the shared variable
9808 procedures have been processed, because the IP call needs to undergo

9820 given a box association, the type of the component is discriminated,
9821 and the value of the discriminant is the discriminant of the enclosing
9822 type, retrieve its value from the aggregate itself, where it must have
9825 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
9826 to remove other spurious ambiguities on arithmetic operations involving
9827 literals and addresses, on systems where Address is a visible integer
9828 type, when the operator is called in functional notation.
9829 (Try_Primitive_Operation): Within an instance, a call in prefixed form
9830 is legal when the types match, even if the operation is currently

9983 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
9984 occurring in the list of entities to qualify, and do not attempt to

10010 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10011 concatenations of string literals into a single literal, in order to
10012 avoid very deep recursion in the front end, which was causing stack
10015 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10016 string, and the right operand is a string literal (the case of "" &
10017 "..."), optimize by avoiding copying the right operand -- just use the
10018 value of the right operand directly.
10020 * stringt.adb (Store_String_Chars): Optimize by growing the
10021 String_Chars table all at once, rather than appending characters one by
10023 (Write_String_Table_Entry): If the string to be printed is very long,
10024 just print the first few characters, followed by the length. Otherwise,
10025 doing "pn(n)" in the debugger can take an extremely long time.
10027 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10028 Store_String_Char with Store_String_Chars.

10047 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10048 flag, for effiency. It is called when analyzing arithmetic operators
10049 and also for actuals in calls that are universal_integers. The flag is
10050 set for the predefined type address, and for any type or subtype
10053 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10054 Universal_Integer, when the formal is a descendent of address and the
10055 call appears in user code.

10120 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10122 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10123 associated with Standard_Debug_Renaming_Type, to be used as the type of
10124 the special variables whose names provide debugger encodings for
10125 renaming declarations.
10127 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10128 (Set_Debug_Renaming_Link): Change to set Node25.

10138 and the entity of the renaming declaration.
10139 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10140 part of the name of a variable that has a Debug_Renaming_Link.
10142 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a

10147 Ed Schonberg <schonberg@adacore.com>
10148 Javier Miranda <miranda@adacore.com>
10150 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10151 ancestor part given by an aggregate to test for an unchecked conversion,
10152 since this can occur in some cases when the ancestor part is a function
10153 call, and we don't want to fall into the recursive call to this
10154 procedure in that case.
10156 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10157 stream attributes on limited types to account for user-specified
10158 attributes as well as whether Input (resp. Output) becomes available
10159 due to Read (resp. Write) being available for the type. Change Boolean
10160 variable to the more accurate name
10161 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10162 double-"not" predicate at beginning of return statement to more
10163 understandable form.
10165 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10166 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10167 in a block statement and use that as the first statement of the
10168 expanded return rather than incorrectly using the handled sequence as
10169 the first statement.
10171 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10172 operation, generate an explicit freeze node for it rather than
10173 generating extra formals, to ensure that gigi has the proper order of
10174 elaboration for anonymous subtypes in the signature of the subprograms.
10175 (Build_In_Place_Formal): Move assertion to beginning of loop.
10176 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

10181 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10182 2005, generate an extended return statement enclosing the result object
10185 * freeze.adb (Freeze_Record_Type): Extend the current management of
10186 components that are access type with an allocator as default value: add
10187 missing support to the use of qualified expressions of the
10188 allocator (which also cause freezing of the designated type!)
10189 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10190 dispatching operation, since extra formals may be needed by calls to
10191 build-in-place functions (such as stream 'Input).
10193 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10194 formals for 'Constrained and accessibility level in the case of a
10195 predefined dispatching operation.
10197 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10198 point, no need to find the parent node.
10200 2007-08-16 Javier Miranda <miranda@adacore.com>
10202 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10203 and entry barriers.
10205 2007-08-16 Javier Miranda <miranda@adacore.com>
10207 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10208 is not really required and can introduce regression with the debugger.
10209 The original problem is fixed with the patch written for checks.adb.
10211 2007-08-16 Thomas Quinot <quinot@adacore.com>
10213 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10223 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10224 parameter Including_Non_Switch, defaulted to True. When
10225 Including_Non_Switch is False, options that are not switches and
10226 appear as relative path are not converted to absolute paths.
10228 2007-08-16 Nicolas Roche <roche@adacore.com>

10241 from the immediate ancestor of Main_Unit_Entity.
10242 (Install_Limited_Withed_Unit): Do not install the limited view of
10243 package P if P is reachable through an ancestor chain from package C
10244 and C also has a with clause for P in its body.
10245 (Has_Limited_With_Clause): New routine.
10246 (Has_With_Clause): New routine.
10248 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10250 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10251 generic for an enclosing instance is a global reference, even though
10252 its scope is the enclosing instance.

10278 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10279 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10280 the statement which is being resolved comes from a predefined library
10281 unit, all non-predefined library interpretations are skipped.
10282 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10283 but the "&" is user defined, give an error, because the folding would
10286 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
10287 the parser has folded a long sequence of concatenations of string
10290 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10291 and "JMP_BUF" variables as artificial.
10292 (N_String_Literal): Do not use alloca for very long string literals. Use

10338 Ed Schonberg <schonberg@adacore.com>
10340 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10341 Suppress unmodified in-out parameter warning in some cases
10342 This patch is a also fairly significant change to the way suppressible
10343 checks are handled.
10345 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10346 needed for access to concurrent record types generated by the expander.
10347 (Generate_Range_Check): When generating a temporary to capture the
10348 value of a conversion that requires a range check, set the type of the
10349 temporary before rewriting the node, so that the type is always
10350 properly placed for back-end use.
10351 (Apply_Float_Conversion_Check): Handle case where the conversion is
10353 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10354 for a protected type in order to examine its discriminants.

10361 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10362 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10363 tests optimized out.

10366 (Get_Allocator_Final_List): For the case of an anonymous access type
10367 that has a specified Associated_Final_Chain, do not go up to the
10369 (Expand_N_Type_Conversion): Test for the case of renamings of access
10370 parameters when deciding whether to apply a run-time accessibility
10372 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10373 aggregate code before allocator, and ahead of declaration for
10374 temporary, to prevent access before elaboration when the allocator is
10375 an actual for an access parameter.
10376 (Expand_N_Type_Conversion): On an access type conversion involving an
10377 access parameter, do not apply an accessibility check when the
10378 operand's original node was an attribute other than 'Access. We now
10379 create access conversions for the expansion of 'Unchecked_Access and
10380 'Unrestricted_Access in certain cases and clearly accessibility should
10381 not be checked for those.
10383 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10384 includes a type conversion of a packed component that has been expanded,
10385 recover the original expression for the object, and use this expression
10386 in the post-call assignment statement, so that the assignment is made
10387 to the object and not to a back-end temporary.
10388 (Freeze_Subprogram): In case of primitives of tagged types not defined
10389 at the library level force generation of code to register the primitive
10390 in the dispatch table. In addition some code reorganization has been
10391 done to leave the implementation clear.
10392 (Expand_Call): When expanding an inherited implicit conversion,
10393 preserve the type of the inherited function after the intrinsic
10394 operation has been expanded.
10396 * exp_ch2.ads, exp_ch2.adb
10397 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10398 of an entry formal appearing in an assignment statement does not assign
10400 (Expand_Current_Value): Instead of calling a routine to determine
10401 whether the prefix of an attribute reference should be optimized or
10402 not, prevent the optimization of such prefixes all together.
10404 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10405 component whose prefix is known to be of an access type is an implicit
10406 dereference and does not assign to the prefix.
10408 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10409 Robert Dewar <dewar@adacore.com>
10411 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10412 itype is visited, make an entry into table to link associated node and
10414 Add comments and correct harmless error in Build_NCT_Hash_Tables
10415 (Array_Aggr_Subtype): Associate each itype created for an index type to
10416 the corresponding range construct, and not to the aggregate itself. to
10417 maintain a one-to-one correspondence between itype and its associated
10418 node, to prevent errors when complex expression is copied.
10419 Fix mishandling of multiple levels of parens
10421 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10422 treatment of limited views uniform for all visible declarations in a
10423 limited_withed package.
10424 (New_Copy_Tree): If hash table is being used and itype is visited,
10425 make an entry into table to link associated node and new itype.
10426 (Resolve_Record_Aggregate): Do not add an others box association for a
10427 discriminated record component that has only discriminants, when there
10428 is a box association for the component itself.
10430 * par-ch4.adb: Fix mishandling of multiple levels of parens
10432 2007-08-14 Robert Dewar <dewar@adacore.com>

10469 to make treatment of limited views uniform for all visible declarations
10470 in a limited_withed package.
10471 Improve warnings for in out parameters
10472 (Set_Related_Interaface/Related_Interface): Allow the use of this
10473 attribute with constants.
10474 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10475 Warn on duplicate pragma Preelaborable_Initialialization
10477 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10478 generation of a freezing node to ensure proper management of null
10479 excluding access types in the backend.
10480 (Create_Extra_Formals): Test base type of the formal when checking for
10481 the need to add an extra accessibility-level formal. Pass the entity E
10482 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10483 originally being done in a couple of cases), to ensure that the
10484 Extra_Formals list gets set on the entity E when the first entity is
10486 (Conforming_Types): Add missing calls to Base_Type to the code that
10487 handles anonymous access types. This is required to handle the
10488 general case because Process_Formals builds internal subtype entities
10489 to handle null-excluding access types.
10490 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10491 functions that need it, even when not marked Requires_Overriding.
10492 Improve warnings for in out parameters
10493 (Analyze_Function_Return): Warn for disallowed null return
10494 Warn on return from procedure with unset out parameter
10495 Ensure consistent use of # in error messages
10496 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10497 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10498 the implicit conversion of the expression done for anonymous access
10499 types. This is required to generate the code of the null excluding
10500 check (if required).
10502 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10503 A formal parameter is never publicly referenceable outside of its body.
10504 (Check_References): For an unreferenced formal parameter in an accept
10505 statement, use the same warning circuitry as for subprogram formal
10507 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10508 Output_Unreferenced_Messages, containing the part of that routine that
10509 is now reused for entry formals as described above.
10510 (Goto_Spec_Entity): New function
10511 (Check_References): Do not give IN OUT warning for dispatching operation
10512 Improve warnings for in out parameters

10520 Gary Dismukes <dismukes@adacore.com>
10522 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10523 (Expand_N_Attribute_Reference): Further unify the handling of the
10524 three forms of access attributes, using common code now for all three
10525 cases. Add a test for the case of applying an access attribute to
10526 an explicit dereference when the context is an access-to-interface
10527 type. In that case we need to apply the conversion to the prefix
10528 of the explicit dereference rather than the prefix of the attribute.
10529 (Attribute_Version, UET_Address): Set entity as internal to ensure
10530 proper dg output of implicit importation.
10531 (Expand_Access_To_Type): Removed.
10532 (Expand_N_Attribute_Reference): Merge the code from the three cases
10533 of access attributes, since the processing is largely identical for
10534 these cases. The substantive fix here is to process the case of a
10535 type name prefix (current instance case) before handling the case
10536 of interface prefixes.

10541 Robert Dewar <dewar@adacore.com>
10543 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10544 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10545 type that is an anonymous access to controlled object, establish
10546 an associated finalization chain to avoid corrupting the global
10547 finalization list when a dynamically allocated object designated
10548 by such a component is deallocated.
10549 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10550 functions that need it, even when not marked Requires_Overriding.
10551 (Initialize_Tag): Replace call to has_discriminants by call to
10552 Is_Variable_Size_Record in the circuitry that handles the
10553 initialization of secondary tags.
10554 (Is_Variable_Size_Record): New implementation.
10555 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10556 Suppress_Initialization pragma for a derived type.
10557 (Is_Variable_Size_Record): New subprogram.
10558 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10559 initial version of this routine and also fixes problems causing
10560 incomplete initialization of the table of interfaces.
10561 (Build_Init_Procedure): Improve the generation of code to initialize the
10562 the tag components of secondary dispatch tables.
10563 (Init_Secondary_Tags): New implementation that simplifies the previous
10564 version of this routine.
10565 (Make_DT): Add parameter to indicate when type has been frozen by an
10566 object declaration, for diagnostic purposes.
10567 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10568 diagnose attemps to freeze a subprogram when some untagged type of its
10569 profile is a private type whose full view has not been analyzed yet.
10570 (Freeze_Array_Type): Generate init proc for packed array if either
10571 Initialize or Normalize_Scalars is set.
10572 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10573 constructing the new profile, copy the null_exclusion indicator for each
10574 parameter, to ensure full conformance of the new body with the spec.
10576 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10577 Create wrappers for constructor functions that need it, even when not
10578 marked Requires_Overriding.
10579 (Covers): Handle properly designated types of anonymous access types,
10580 whose non-limited views are themselves incomplete types.
10581 (Add_Entry): Use an entity to store the abstract operation which hides
10583 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10584 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10585 initialization aggregate.
10586 (Function_Interp_May_Be_Hidden): Rename to
10587 Function_Interp_Has_Abstract_Op.
10588 (Has_Compatible_Type): Remove machinery that skips interpretations if
10589 they are labeled as potentially hidden by an abstract operator.
10590 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10591 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10592 (Write_Overloads): Output the abstract operator if present.
10593 (Add_Entry): Before inserting a new entry into the interpretation table
10594 for a node, determine whether the entry will be disabled by an abstract

10597 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10599 (Function_Interp_May_Be_Hidden): New routine.
10600 (Has_Compatible_Type): Do not consider interpretations hidden by
10601 abstract operators when trying to determine whether two types are
10603 (Has_Hidden_Interp): New routine.
10604 (Set_May_Be_Hidden_Interp): New routine.
10605 (Write_Overloads): Write the status of flag May_Be_Hidden.

10610 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
10611 types declared in the declarative part of a nested package body or in
10612 the proper body of a stub.
10613 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10614 of the same dispatch table slot to renamed primitives.
10615 (Make_Select_Specific_Data_Table): Handle private types.
10616 (Tagged_Kind): Handle private types.
10617 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10618 output of implicit importation and exportation.
10619 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10620 first formal of the thunk is always associated with the controlling
10621 type. In addition perform the following code cleanup: remove formal
10622 Thunk_Alias which is no longer required, cleanup evaluation of the
10623 the controlling type, and update the documentation.
10624 Replace occurrence of Default_Prim_Op_Count by
10625 Max_Predef_Prims. Addition of compile-time check to verify
10626 that the value of Max_Predef_Prims is correct.
10627 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10628 (Make_DT): Add parameter to indicate when type has been frozen by an
10629 object declaration, for diagnostic purposes.
10630 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10631 construction of statically allocated dispatch tables.
10632 (Make_DT): In case of library-level tagged types export the declaration
10633 of the primary tag. Remove generation of tags (now done by Make_Tags).
10634 Additional modifications to handle non-static generation of dispatch
10635 tables. Take care of building tables for asynchronous interface types
10636 (Make_Tags): New subprogram that generates the entities associated with
10637 the primary and secondary tags of Typ and fills the contents of Access_
10638 Disp_Table. In case of library-level tagged types imports the forward
10639 declaration of the primary tag that will be declared later by Make_DT.
10640 (Expand_Interface_Conversion): In case of access types to interfaces
10641 replace an itype declaration by an explicit type declaration to avoid
10642 problems associated with the scope of such itype in transient blocks.

10645 Ed Schonberg <schonberg@adacore.com>
10646 Javier Miranda <miranda@adacore.com>
10648 * exp_util.ads, exp_util.adb:
10649 This patch replaces a number of occurrences of explicit tests for N_Null
10650 with calls to Known_Null. This improves tracking of null values, since
10651 Known_Null also catches null constants, and variables currently known to
10652 be null, so we get better tracking.
10653 (Ensure_Defined): create an itype reference only in the scope of the
10655 (Side_Effect_Free): A selected component of an access type that
10656 denotes a component with a rep clause must be treated as not
10657 side-effect free, because if it is part of a linked structure its
10658 value may be affected by a renaming.
10659 (Expand_Subtype_From_Expr): For limited objects initialized with build
10660 in place function calls, do nothing; otherwise we prematurely introduce
10661 an N_Reference node in the expression initializing the object, which
10662 breaks the circuitry that detects and adds the additional arguments to
10663 the called function. Bug found working in the new patch for statically
10664 allocated dispatch tables.
10665 (Is_Library_Level_Tagged_Type): New subprogram.
10666 (Remove_Side_Effects): If the expression of an elementary type is an
10667 operator treat as a function call.
10668 (Make_Literal_Range): If the index type of the array is not integer, use
10669 attributes properly to compute the constraint on the resulting aggregate
10672 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10673 class-wide type whose base type is an incomplete private type, leave
10674 class-wide type unfrozen so that freeze nodes can be generated
10675 properly at a later point.
10676 (Freeze_Entity, array case): Handle case of pragma Pack and component
10677 size attributre clause for same array.
10679 2007-08-14 Vincent Celier <celier@adacore.com>

10733 (Search_Directories): Detect subunits that are specified with an
10734 attribute Body in package Naming. Do not replace a source/unit in the
10735 same project when the order of the source dirs are known. Detect
10736 duplicate sources/units in the same project when the order of the
10737 source dirs are not known.
10738 (Check_Ada_Name): Allow all identifiers that are not reserved words
10740 Major update of the Project Manager and of the project aware tools,
10741 including gprmake, so that the same sources in the GNAT repository
10742 can be used by gprbuild.

10744 directory of non extending project to nil.
10745 Change type of path name variables to be Path_Name_Type
10746 (Locate_Directory): Make sure that on Windows '/' is converted to '\',

11326 operations in Derive_Subprograms.
11327 (Collect_Previous_Instances): new procedure within of
11328 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11329 unit being loaded, to ensure that the generation of global symbols is

11331 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11332 takes progenitor types into account.
11333 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11334 traversing over the primitives of the formal and actual types to locate
11335 any abstract subprograms of the actual type that correspond to a
11336 nonabstract subprogram of the formal type's ancestor type(s), and issue
11337 an error if such is found.
11338 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11339 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11340 Remove bogus guard around calls to Inherit_Context.

11353 an access_to_constant type.
11354 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11355 type, the candidate operations are found in the scope of declaration of
11356 the type, because the type has no primitive subprograms.
11357 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11358 a private extension, only examine visible components before trying to
11359 analyze as a prefixed call.
11360 Change Entity_List to Type_To_Use, for better readability.

11373 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11374 purpose of enforcing E.2.2(8) only if it is not available at any place.
11375 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11376 when checking the legality of an extension aggregate in a preelaborable
11377 package. Treat the literal null as a valid default expression in a
11378 component declaration for a type with preelaborable initialization.
11379 A limited interface is a legal progenitor for the designated type of a
11380 remote access to class-wide type.

11393 (Find_Selected_Component, Has_Components): Handle properly non-limited
11394 views that are themselves incomplete types.
11395 Handle interfaces visible through limited-with clauses.
11396 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11397 subprogram generic actual for which we have generated a renaming.
11398 Warn when the renaming introduces a homonym of
11399 the renamed entity, and the renamed entity is directly visible.

11410 when the type of the interpretation matches that of the context.
11411 (Resolve): When looping through all possible interpretations of a node,
11412 do not consider those that are hidden by abstract operators.
11413 (Resolve_Actuals): When verifying that an access to class-wide object
11414 is an actual for a controlling formal, ignore anonymous access to
11415 subprograms whose return type is an access to class_wide type.
11416 (Resolve_Slice): If the prefix of the slice is a selected component
11417 whose type depends on discriminants, build its actual subtype before
11418 applying range checks on the bounds of the slice.
11419 (Valid_Conversion): In an instance or inlined body, compare root types,
11420 to prevent anomalies between private and public views.

11442 elabration statements, register the package with the name server
11443 at the beginning, not at the end, of the elaboration statements so
11444 that they can create remote access to subprogram values that designate
11445 remote subprograms from the package.

11655 Add s-osinte-vxworks-kernel.adb to the target pairs of the
11656 kernel run-time lib for VxWorks 6, which would provide a different
11657 implementation for Task_Cont and Task_Stop than the VxWorks 5 version.

12533 Output_Linker_Option_List is set. Suppress this formatting when
12534 Zero_Formatting is set.
12535 Add case for CLI_Target.
12536 (System_Restrictions_Used): New flag, used to avoid generating with of
12537 System_Restrictions and initialization of the data unless there is
12538 some use of System.Restrictions in the partition.
12539 (Check_System_Restrictions_Used): New procedure
12541 * s-stalib.adb: Remove with of System.Restrictions. No longer needed
12542 since we only with this unit in the binder file if it is used elsewhere
12545 2007-06-06 Vincent Celier <celier@adacore.com>
12547 * bindusg.adb: Add line for @<response file>
12548 Add lines for new switches -R and -Z
12550 * gnatbind.adb (Gnatbind): Do not include sources from the GNAT
12551 hierarchy in the list of files of the closure when -R is used
12552 (Gnatbind): Accept arguments starting with '@' to indicate response
12553 files and take the arguments from the response files.
12554 If List_Closure is set, display the referenced files

12557 Robert Dewar <dewar@adacore.com>
12558 Ed Schonberg <schonberg@adacore.com>
12560 * checks.ads, checks.adb (Apply_Address_Clause_Check): Handle case in
12561 which the address-clause is applied to in-mode actuals (allowed by
12563 (Apply_Discriminant_Check): Do not generate a check if the type is
12564 constrained by a current instance.
12565 (Activate_Division_Check): New procedure
12566 (Activate_Overflow_Check): New procedure
12567 (Activate_Range_Check): New procedure
12568 Call these new Activate procedures instead of setting flags directly
12569 (Apply_Array_Size_Check): Removed, no longer needed.
12570 Code clean up: remove obsolete code related to GCC 2.
12571 (Get_E_Length): Protect against bomb in case scope is standard
12572 (Selected_Range_Checks): If the node to be checked is a conversion to
12573 an unconstrained array type, and the expression is a slice, use the
12574 bounds of the slice to construct the required constraint checks.
12575 Improve NOT NULL error messages
12576 (Apply_Constraint_Check): If the context is a null-excluding access
12577 type, diagnose properly the literal null.
12579 2007-06-06 Pascal Obry <obry@adacore.com>
12581 * clean.adb (Clean_Archive): Use untouched casing for the archive name
12582 and the corresponding .deps file.
12583 (Clean_Interface_Copy_Directory): Use untouched casing for the library
12584 src directory. Minor code-clean-up. Use untouched casing for files
12585 read into the library src dir.

12592 Eric Botcazou <ebotcazou@adacore.com>
12593 Arnaud Charlet <charlet@adacore.com>
12595 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12596 applicable to types that have the With_Type flag set. Returns the
12597 non-limited view of the type, if available, otherwise the type itself.
12598 For class-wide types, there is no direct link in the tree, so we have
12599 to retrieve the class-wide type of the non-limited view of the Etype.
12600 New attributes Static_Initialization and Static_Elaboration_Desired.
12601 Remove the pragma Thread_Body, and the associated flag
12602 Is_Thread_Body in entities, and all related code.
12603 (Suppress_Value_Tracking_On_Call): New flag
12604 E_Exception has Esize and Alignment fields
12605 (Universal_Aliasing): New function.
12606 (Set_Universal_Aliasing): New procedure.
12607 (Write_Entity_Flags): Deal with Universal_Aliasing flag.
12608 (Check_Nested_Access): New procedure.
12609 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
12610 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
12611 (Related_Interface): New attribute. Present in dispatch table pointer
12612 components of records. Set to point to the entity of the corresponding
12614 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
12615 (Original_Access_Type): Remove, not needed.
12616 (Root_Type): Handle properly subtypes of class-wide-types.
12619 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12620 class-wide types visible through limited-with clauses.
12621 (Try_Primitive_Operation): When examining all primitive operations of a
12622 tagged type, do not consider subprograms labeled as hidden unless they
12623 belong to a private generic type with a tagged parent.
12624 (Try_Object_Operation): Extensive rewriting, to handle properly various
12625 overloading cases, when several ancestors may have class-wide operations
12626 that are possible candidates, and when the overloaded functions return
12627 array types and have defaulted parameters so that the call may be
12628 interpreted as an indexing.
12629 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12630 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12631 successive actuals before analyzing the call itself.
12632 (Try_Primitive_Operation): A primitive operation is compatible with the
12633 prefix if the prefix has a synchronized type and the type of the formal
12634 is its corresponding record, as can be the case when the primitive
12635 operation is declared outside of the body of the type.
12636 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12637 perform homonym traversal, looking for class-wide operation matches
12638 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12639 access parameters are now restricted to anonymous access types.
12640 (Mark_Allocator): An allocator with a discriminant association parent is
12642 (Try_One_Prefix_Interpretation): If the type of the object is
12643 incomplete, as can be happen when it is a limited view obtained through
12644 a limited_with_clause, the selected component is not part of a prefixed
12646 (Complete_Object_Operation): Diagnose properly an object that is not
12647 aliased when the corresponding controlling formal is an access
12649 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12650 ambiguous calls in prefixed notation, where two primitives differ only
12651 in that the controlling argument of one is an access parameter.
12653 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12654 whether a function that returns an unconstrained type can be inlined.
12655 (Process_Formals): Diagnose properly the illegal use of an incomplete
12656 type in the profile of an access_to_subprogram declaration.
12657 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12658 operations are attached to the corresponding record.
12659 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12660 When processing a primitive of a concurrent type which implements an
12661 interface change the type of all controlling formals to that of the
12662 corresponding record type.
12663 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12664 to determine the tagged type to which a primitive belongs.
12665 (Check_Conventions): Capture condition to ignore a primitive operation
12666 (which is shared between the loop in Check_Conventions and the one in
12667 Check_Convention) in a new local function Skip_Check.
12668 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12669 confusion with Check_Conventions' own Prim_Op local variable.
12670 (Create_Extra_Formals): Test for a tagged result type rather than a
12671 controlling result when determining whether to add a BIP_Alloc_Form
12672 formal and a BIP_Final_List formal to the function.
12673 (Check_Conformance); For parameters that are anonymous access types,
12674 subtype conformance requires that the not null and the constant
12675 indicators must match
12676 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12677 to retrieve the appropriate type when processing a concurrent type
12678 declared within a generic. Minor comment reformatting. Change invocation
12679 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12681 (Analyze_Subprogram_Body): If the return type of a function is an
12682 anonymous access to the limited view of a class-wide type, and the
12683 non-limited view of the type is available, update the type of the
12684 function so that code can be generated.
12685 (Process_Formals): In case of access-subtype itype whose designated
12686 type is also an itype (situation that happens now with access to
12687 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12688 attribute to avoid backend problems.
12689 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12690 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12691 anonymous types' designated types are same before testing
12692 Subtypes_Statically_Match.
12693 (Create_Extra_Formals): Test for a named access parameter that is a
12694 controlling formal as an additional condition for adding an
12695 accessibility level formal. This can occur in the subp type created for
12696 dispatching calls in Expand_Dispatching_Call, and allows calling
12697 Create_Extra_Formals from that procedure rather than special-casing the
12698 extra formals there.
12699 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12700 when the function has a controlling result.
12701 (Check_Returns): Add much more knowledge of the optimization of local
12702 raise statements to gotos, to retain proper warnings in this case.
12703 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12704 nodes when looking for last statement.
12706 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12707 class-wide types visible through limited with clauses.
12708 (Add_One_Interp): If the operands are anonymous access types, the
12709 predefined operator on universal_access is immediately visibles
12710 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12711 other anonymous access types.
12712 (Disambiguate): Take into account CIL convention.
12713 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12715 2007-06-06 Robert Dewar <dewar@adacore.com>

12720 Fix lower bound of tables.
12723 * nlists.adb: Ditto.
12724 (Prev_Node, Next_Node): Change index type to Int so that it properly
12725 covers the range First_Node_Id - 1 up.
12727 2007-06-06 Javier Miranda <miranda@adacore.com>
12728 Ed Schonberg <schonberg@adacore.com>
12729 Bob Duff <duff@adacore.com>
12730 Hristian Kirtchev <kirtchev@adacore.com>
12732 * exp_aggr.ads, exp_aggr.adb:
12733 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12734 in extension aggregates.
12735 (Flatten): Other conditions being met, an aggregate is static if the
12736 low bound given by component associations is different from the low
12737 bound of the base index type.
12738 (Packed_Array_Aggregate_Handled): If the component type is itself a
12739 packed array or record, the front-end must expand into assignments.
12740 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12741 Init_Pr, instead of Ancestor_Is_Expression.
12742 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12743 coextension chain root, either generate a list controller or use the
12744 already existing one.
12745 (Static_Array_Aggregate): New procedure to construct a positional
12746 aggregate that can be handled by the backend, when all bounds and
12747 components are compile-time known constants.
12748 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12749 types covering interface types into assignments.
12750 (Replace_Type): move to Build_Record_Aggr_Code.
12751 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12752 interface type, convert to the definite type of the aggregate itself,
12753 so that needed components are visible.
12754 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12755 components and the context is an extended return statement do not
12756 create a transient block for it, to prevent premature finalization
12757 before the return is executed.
12758 (Gen_Assign): Do not generate a call to deep adjust routine if the
12759 component type is itself an array of controlled (sub)-components
12760 initialized with an inner aggregate.
12761 (Component_Check): New name for Static_Check. This name is now more
12762 appropriate, and documentation is added which was missing.
12763 (Component_Check): Add test for bit aligned component value
12764 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12765 Tagged_Comps, name is more appropriate given added function below.
12766 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

12770 Robert Dewar <dewar@adacore.com>
12772 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12773 Terminated: Add unchecked type conversion from System.Address to
12774 System.Tasking.Task_Id when calling the predefined primitive
12776 Disable new Ada 05 accessibility check for JVM.NET targets, which
12777 cannot be implemented in a practical way.
12778 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12779 the sources always references the tag of the actual object. Therefore,
12780 if 'Tag is applied in the sources to class-wide interface objects we
12781 generate code that displaces "this" to reference the base of the object.
12782 (Expand_N_Attribute_Reference, case Size): Return specified size if
12783 known to front end.
12784 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12785 has code that displaces the pointer of the object to manage interface
12786 types. However this code must not be executed when the prefix is a
12787 subprogram. This bug caused the wrong expansion of the internally
12788 generated assignment that fills the dispatch table when the primitive
12789 is a function returning a class-wide interface type.
12790 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12791 Set_Attribute_Name for Name_Unaligned_Valid.
12793 2007-06-06 Ed Schonberg <schonberg@adacore.com>
12794 Gary Dismukes <dismukes@adacore.com>
12796 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12797 If the initialization is the equivalent aggregate of the initialization
12798 procedure of the type, do not remove it.
12799 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12800 initialized to null from having their expression reset to empty and
12801 note this exception in the comment.

12809 Add "with" and "use" clauses for Sem_Attr.
12810 (Expand_Current_Value): Do not replace occurences of attribute
12811 references where the prefix must be a simple name.
12813 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
12814 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
12815 Attribute_Requires_Simple_Name_Prefix.
12816 (Name_Modifies_Prefix): Body of new function.
12817 (Requires_Simple_Name_Prefix): Body of new function.

12819 mismatched conventions.
12820 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
12822 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12823 constrained subtype for a nominal unconstrained type, use its base type
12824 to check for conformance with the context.
12825 (Resolve_Attribute): Remove test of the access type being associated
12826 with a return statement from condition for performing accessibility
12827 checks on access attributes, since this case is now captured by
12828 Is_Local_Anonymous_Access.
12829 (Analyze_Access_Attribute): Set Address_Taken on entity
12830 (Analyze_Attribute, case Address): Set Address_Taken on entity
12831 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
12832 validating an access attribute whose prefix is a current instance.
12833 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
12834 applied to dispatching operations, if freezing is required then we set
12835 the attribute Has_Delayed_Freeze in the prefix's entity.
12836 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
12837 current scope if access of local subprogram taken
12838 (Analyze_Access_Attribute): Check legality of self-reference even if the
12839 expression comes from source, as when a single component association in
12840 an aggregate has a box association.
12841 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
12842 the prefix if it is a protected operation and the attribute is
12843 Unrestricted_Access.
12844 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
12845 reference to the base type of the context, to force a constraint check
12846 when the context is an access subtype with an explicit constraint.
12847 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
12848 node is rewritten as an interface conversion. leave unanalyzed after
12849 resolution, to ensure that type checking against the context will take

12853 Javier Miranda <miranda@adacore.com>
12854 Robert Dewar <dewar@adacore.com>
12856 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
12857 wrapper when the full view of the controlling type of an inherited
12858 function that dispatches on result implements interfaces.
12859 (Expand_N_Object_Declaration): In cases where the type of the
12860 declaration is anonymous access, create finalization list for it.
12861 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
12862 if the object has no explicit initialization, to match description of
12863 functionality of pragam Persistent_BSS.
12864 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
12865 new function to build static aggregates, to replace initialization call
12866 when static initialization is desired.
12867 (Freeze_Type): Generate a list controller for an access type whenever
12868 its designated type has controlled anonymous access discriminants.
12869 (Build_Equivalent_Aggregate): New procedure to compute a static
12870 aggregate to be used as default initialization for composite types,
12871 instead of a generating a call to the initialization procedure for the
12873 (Build_Initialization_Call): When available, replace a call to the
12874 initialization procedure with a copy of the equivalent static aggregate
12876 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
12877 declarations for objects of a class-wide interface type, rather than
12878 just identifiers, to prevent visibility problems.
12879 (Expand_N_Object_Declaration): When expanding the declaration for an
12880 object of a class-wide interface type, preserve the homonym chain of
12881 the original entity before exchanging it with that of the generated
12882 renaming declaration.
12883 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
12884 active, because there is no way to handle the exception.
12885 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
12886 to do a minimum decoration of the Access_Disp_Table list.
12887 (Expand_Record_Controller): Avoid the addition of the controller between
12888 the component containing the tag of a secondary dispatch table and its
12889 adjacent component that stores the offset to the base of the object.
12890 This latter component is only generated when the parent type has
12891 discriminants ---documented in Add_Interface_Tag_Components).
12892 (Apply_Array_Size_Check): Removed, no longer needed.
12893 (Expand_N_Full_Type_Declaration): If the type has anonymous access
12894 components, create a Master_Entity for it only if it contains tasks.
12895 (Build_Init_Procedure): Suppress the tag assignment compiling under
12897 (Freeze_Record_Type): Remove code associated with creation of dispatch
12899 (Init_Secondary_Tags): Update type of actuals when generating calls to

12904 if Has_Init_Expression set.
12905 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
12906 Register_Primitive, which provides the same functionality.
12907 (Requires_Init_Proc): Return false in case of interface types.
12908 (Add_Secondary_Tables): Use the new attribute Related_Interface to
12910 (Predefined_Primitive_Freeze): Do not assume that an internal entity
12911 is always associated with a predefined primitive because the internal
12912 entities associated with interface types are not predefined primitives.
12913 Therefore, the call to Is_Internal is replaced by a call to the
12914 function Is_Predefined_Dispatching_Operation.
12915 (Make_Eq_If): When generating the list of comparisons for the
12916 components of a given variant, omit the controller component that is
12917 present if the variant has controlled components.

12920 Hristian Kirtchev <kirtchev@adacore.com>
12921 Bob Duff <duff@adacore.com>
12923 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
12924 handle the creation of finalization lists and calls for nested
12925 coextensions when the root of the chains is part of a return statement.
12926 (Inside_A_Return_Statement): New function inside Complete_Coextension_
12928 (Expand_Record_Equality): Skip components that are interface types.
12929 (Displace_Allocator_Pointer): Add missing support for interface subtypes
12930 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
12931 with Rewrite_Coextension. Change the condition for detecting coextension
12933 (Is_Local_Access_Discriminant): Removed.
12934 (Rewrite_Coextension): New routine which rewrites a static coextension
12935 as a temporary and uses its unrestricted access in the construction of
12937 (Complete_Coextension_Finalization): New routine. Generate finalization
12938 attachment calls to all delayed coextensions.
12939 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
12940 the allocator is not a coextension itself and has delayed coextensions.
12941 If the current allocator is controlled, but also a coextension, delay
12942 the generation of the finalization attachment call.
12943 Rename local variable "Node" to "Nod" in order to avoid confusion with
12945 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
12946 limited types that are not inherently limited. Such an allocator is
12947 illegal, but is generated by the expander for a return statement, to
12948 copy the result onto the secondary stack. This is the only case where a
12949 limited object can be copied. Generate code to displace the pointer
12950 to the object if the qualified expression is a class-wide interface
12951 object. Such displacement was missing and hence the copy of the object
12953 (Apply_Accessibility_Check): Handle allocated objects initialized in
12955 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
12956 and Expand_Allocator_Expression. Allocating class-wide interface objects
12957 this routine displaces the pointer to the allocated object to reference
12958 the component referencing the corresponding secondary dispatch table.
12959 Expand_Allocator_Expression): Add missing support to allocate class-wide
12960 interface objects initialized with a qualified expression.
12961 (Get_Allocator_Final_List): Test for an anonymous access type that is a
12962 function result type, and use the finalization list associated with the
12963 function scope in that case (such an anonymous type should not be
12964 treated like an access parameter's type).
12966 2007-06-06 Ed Schonberg <schonberg@adacore.com>
12967 Gary Dismukes <dismukes@adacore.com>
12968 Javier Miranda <miranda@adacore.com>
12970 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
12971 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
12972 required exception handler.
12973 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
12974 properly the case of a function whose return type is a limited
12975 class-wide interface type. Modify the code of the accessibility
12976 check to handle class-wide interface objects. In this case we need to
12977 displace "this" to reference the primary dispatch table to get access
12978 to the TSD of the object (to evaluate its accessibility level).
12979 (Expand_N_Extended_Return_Statement): Test for a tagged result type
12980 rather than a controlling result as one of the conditions for
12981 generating tests of the implicit BIP_Alloc_Form formal. The
12982 initialization assignment is also handled according to whether the
12983 result is tagged instead of controlling.
12984 In the case where the init assignment is inserted in the "then" part of
12985 the allocation conditional, rewrite the target to be a dereference of
12986 the implicit BIP_Object_Access formal.
12987 If the returned value is unconstrained and created on the secondary
12988 stack, mark the enclosing block and function so that the secondary
12989 stack is not reclaimed on return.
12990 Treat returns from functions with controlling results similarly to
12991 returns from functions with unconstrained result subtypes.
12992 If the object returned is unconstrained, and an allocator must be
12993 created for it, analyze the allocator once the block for the extended
12994 return is installed, to ensure that finalizable components
12995 of the expression use the proper finalization list. Guard the call to
12996 Move_Final_List with a check that there is something to finalize.
12997 (Make_Tag_Ctrl_Assignment): Use "old" handling
12998 of controlled type assignment for virtual machines, since new code uses
12999 unsupported features (such as direct access to bytes in memory).
13001 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13002 Ed Schonberg <schonberg@adacore.com>
13004 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13005 accessibility actual, check for the case of an aliased object that has
13006 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13007 we fall into processing for the attribute rather than the name of the
13009 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13010 formal has its address taken in the body, create a temporary to capture
13011 value. If the return type is a limited interface, do not treat the
13012 return value as Controlled.
13013 (Is_In_Place_Function): If the return type is a limited interface,
13014 treat as returning in place. The actual returned object may not always
13015 be limited, but the caller has to assume that it is returned in place.
13016 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13017 context of an allocator, use the correct finalization chain (that is,
13018 the chain belonging to the access type, rather than the chain belonging
13019 to the current scope).
13020 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13021 result type rather than a controlling result as a precondition for
13022 adding an allocation form actual to a build-in-place call.
13023 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13024 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13025 primitive in the dispatch tables. This work is now done by Make_DT when
13026 the type is frozen.
13027 (Register_Predefined_DT_Entry): Removed.
13028 (Add_Return): If end label is not present, use sloc of last statement
13029 for generated return statement in procedure, for better gdb behavior
13031 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13032 object address nodes to ensure proper processing by routines like
13034 (Expand_Call): Fix generation of validity check for parameter
13035 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13036 the allocation form parameter if the result subtype is constrained,
13037 except when the function has a controlling result.
13038 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13039 rather than Is_Controlled and Has_Controlled_Component, since we want to
13040 include class-wide result types in this treatment. Also test for a
13041 controlling result, since that also requires passing a finalization
13043 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13044 even when the result subtype is constrained, to handle calls involving
13045 controlling results.
13046 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13047 is now called even when the result subtype is constrained, to handle
13048 calls involving controlling results.
13049 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13050 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13051 now performs the test).
13052 (Make_Build_In_Place_Call_In_Object_Declaration):
13053 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13054 constrained, to handle calls involving controlling results.
13055 (Add_Return): Accomodate rewritten pattern from local raise to goto
13056 transformation, so that we still recognize an transfer statement
13057 and do the right thing here in that case.
13058 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13059 and end of subprogram code.
13060 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13061 support for primitives that are functions (without formals) with a
13062 controlling result.
13063 (Inherited_From_Formal): If the actual subtype has not generic parent
13064 type, it is not an actual for a formal derived type, and there is no
13065 operation to inherit from the formal.
13067 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13068 Thomas Quinot <quinot@adacore.com>
13070 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13071 inserted cleanup code appropriately for GDB use.
13072 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13073 exception handler for Deep_Adjust or Deep_Finalize.
13074 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13075 Raise_From_Controlled_Operation is available, use a call to that
13076 subprogram instead of a plain "raise Program_Error" node to raise
13077 Program_Error if an exception is propagated from an Adjust or Finalize
13079 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13080 appears in the optional statement list of a triggering alternative, the
13081 scope actions can be inserted directly there, and not in the list that
13082 includes the asynchronous select itself.
13084 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13085 Robert Dewar <dewar@adacore.com>
13086 Hristian Kirtchev <kirtchev@adacore.com>
13088 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13089 generated exception handler appropriately when debugging generated code.
13090 Deal properly with No_Exception_Propagation restriction mode.
13091 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13092 System.Address to System.Tasking.Task_Id when processing the result of
13093 the predefined primitive _disp_get_task_id.
13094 (Expand_N_Asynchronous_Select): Clarify comment.
13095 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13096 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13097 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13098 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13099 privals and for generated call to Complete_Entry_Body, for better gdb
13101 (Copy_Result_Type): Utility to construct a parameter and result profile
13102 for protected functions whose return type is an anonymous access to
13104 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13106 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13107 point when the local-raise-to-goto transformation has taken place.
13109 2007-06-06 Javier Miranda <miranda@adacore.com>
13110 Nicolas Setton <setton@adacore.com>
13112 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13113 functionality when the backend is generating code.
13114 Otherwise any serious error
13115 reported by the backend calling the frontend routine Error_Msg
13116 changes the Compilation_Mode to Check_Semantics, disables the
13117 functionality of this routine and causes the generation of
13118 spureous additional errors.
13120 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13121 debugging information now generated by the compiler for fat-pointer
13123 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13125 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13127 2007-06-06 Thomas Quinot <quinot@adacore.com>
13129 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13130 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13131 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13132 For a remote call to a function with a classwide return type, apply an
13133 E.4(18) check to the returned value.
13134 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13135 stream attributes of the designated type of an RACW, as they are not
13136 dispatching primitive operations.
13138 2007-06-06 Geert Bosch <bosch@adacore.com>
13140 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13142 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13144 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13145 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13147 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13149 2007-06-06 Javier Miranda <miranda@adacore.com>
13151 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13152 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13154 2007-06-06 Javier Miranda <miranda@adacore.com>
13156 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13157 deallocation of class-wide interface objects.
13158 (Expand_Dispatching_Constructor_Call): Take into account that if the
13159 result of the dispatching constructor is an interface type, the
13160 function returns a class-wide interface type; otherwise the returned
13161 object would be actual. The frontend previously accepted returning
13162 interface types because Expand_Interface_Actuals silently performed
13163 the management of the returned type "as if" it were a class-wide
13165 (Expand_Dispatching_Constructor_Call): Replace call to
13166 Make_DT_Access_Action by direct call to Make_Function_Call.
13168 2007-06-06 Robert Dewar <dewar@adacore.com>
13169 Ed Schonberg <schonberg@adacore.com>
13171 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13172 compute masking constant, since we now set Esize properly to the
13174 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13175 to match the alignment.
13176 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13177 packed arrays of 8 bits or less.
13179 * freeze.adb (Freeze_Entity): When freezing the formals of a
13180 subprogram, freeze the designated type of a parameter of an access type
13181 only if it is an access parameter.
13182 Increase size of C convention enumeration object
13183 (Freeze_Entity, array type case): Make sure Esize value is properly
13184 adjusted for the alignment if it is known.
13185 (Freeze_Entity, array type case): When checking bit packed arrays for
13186 the size being incorrect, check RM_Size, not Esize.
13187 (Freeze_Record_Type): Check for bad discriminated record convention
13188 (In_Exp_Body): Return true if the body is generated for a subprogram
13189 renaming, either an attribute renaming or a renaming as body.
13190 (Check_Itype): If the designated type of an anonymous access component
13191 is a non-protected subprogram type, indicate that it is frozen, to
13192 prevent out-of-scope freeze node at some subsequent call.
13193 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13194 only if the subprogram is neither imported nor exported, as well as the
13195 NCA descriptor class if the subprogram is exported.
13197 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13198 Arnaud Charlet <charlet@adacore.com>
13199 Robert Dewar <dewar@adacore.com>
13200 Gary Dismukes <dismukes@adacore.com>
13202 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13203 default initialization on an imported object, when there is no
13204 initialization call generated for it.
13205 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13208 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13209 Static_Elaboration_Desired.
13210 Remove pragma Thread_Body.
13211 Implement a new pragma No_Body
13212 Removes the Explicit_Overriding pragma
13213 Remove Optional_Overriding pragma
13214 (Prag): Deal with Universal_Aliasing.
13215 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13216 Pragma_CIL_Constructor): New names.
13218 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13219 uses the equivalent aggregate of a type must be treated as an implicit
13221 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13222 has none of the other categories.
13223 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13224 to apply Import to an object renaming declaration.
13226 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13227 from a C++ class should be declared as limited and that it will be
13228 considererd limited.
13229 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13230 should be declared as limited and that it will be considererd limited.
13231 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13232 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
13233 (Analyze_Pragma): Deal with Universal_Aliasing.
13234 (Sig_Flags): Likewise.
13235 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
13236 (Overflow_Checks_Unsuppressed): New flag.
13237 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
13238 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
13239 case of JVM or .NET targets, and compiling user code.
13240 Add debugging convenience routine rv
13242 2007-06-06 Robert Dewar <dewar@adacore.com>
13244 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
13245 are interface type.

13249 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
13250 set to value that does not match base type size.
13252 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13254 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13255 object of a limited type can be initialized with a call to a function
13256 that returns in place. If the limited type has unknown discriminants,
13257 and the underlying type is a constrained composite type, build an actual
13258 subtype from the function call, as is done for private types.
13259 (Side_Effect_Free): An expression that is the renaming of an object or
13260 whose prefix is the renaming of a object, is not side-effect free
13261 because it may be assigned through the renaming and its value must be
13262 captured in a temporary.
13263 (Has_Controlled_Coextensions): New routine.
13264 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13265 as is done for other limited types.
13266 (Non_Limited_Designated_Type): new predicate.
13267 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
13269 Remove all handling of with_type clauses.

13273 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
13274 checksum if the main source could not be parsed.
13275 (Loat_Unit): When processing a child unit, determine properly whether
13276 the parent unit is a renaming when the parent is itself a child unit.
13277 Remove handling of with_type clauses.
13279 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

13290 2007-06-06 Vincent Celier <celier@adacore.com>
13291 Robert Dewar <dewar@adacore.com>
13293 * frontend.adb (Frontend): Return immediately if the main source could
13294 not be parsed, because of preprocessing errors.
13296 * gnat1drv.adb (gnat1drv): Handle RE_Not_Available gracefully.
13297 (Gnat1drv): Exit with errors if the main source could not be parsed,
13298 because of preprocessing errors.

13312 Ed Schonberg <schonberg@adacore.com>
13314 * g-comlin.ads, g-comlin.adb:
13315 Add new warning for renaming of function return objects
13317 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
13318 (Tree_Read): Use size of object instead of type'object_size, since the
13319 latter is incorrect for packed array types.
13320 (Tree_Write): Same fix
13322 * opt.ads: Add new warning for renaming of function return objects
13323 (Generating_Code): New boolean variable used to indicate that the
13324 frontend as finished its work and has called the backend to process
13325 the tree and generate the object file.

13333 (Warn_On_Unrepped_Components): New flag.
13335 * sem_ch8.adb (Check_Library_Unit_Renaming): Check that the renamed
13336 unit is a compilation unit, rather than relying on its scope, so that
13337 Standard can be renamed.
13338 (Analyze_Object_Renaming): Add new warning for renaming of function
13340 Also reject attempt to rename function return object in Ada 83 mode.
13341 (Attribute_Renaming): In case of tagged types, add the body of the
13342 generated function to the freezing actions of the type.
13343 (Find_Type): A protected type is visible right after the reserved word
13344 "is" is encountered in its type declaration. Set the entity and type
13345 rather than emitting an error message.
13346 (New_Scope): Properly propagate Discard_Names to inner scopes
13347 (Check_Nested_Access): New procedure.
13348 (Has_Nested_Access, Set_Has_Nested_Access): New procedures.

13360 Olivier Hainque <hainque@adacore.com>
13362 * g-debpoo.ads, g-debpoo.adb (Free_Physically.Free_Blocks): Use the
13363 absolute value of Header.Block_Size when displaying the freed physical
13365 (Allocate): Compute Storage_Address using Integer_Address, not
13366 Storage_Offset, because the range of Storage_Offset may not be large
13368 (Configure): New parameter Low_Level_Traces
13369 (Allocate, Deallocation, Free_Physically): Added low-level traces
13370 (Configure): new parameter Errors_To_Stdout.
13371 (Output_File): new subprogram
13372 (Deallocate, Dereference): Send error messages to the proper stream
13373 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
13374 documented. Previous code would send it to the current output file
13375 defined in GNAT.IO, which might not be stdout
13376 (Is_Valid): Adjust comment to mention that a positive reply means that
13377 Header_Of may be used to retrieve the allocation header associated with
13378 the subprogram Storage address argument. Return False early if this
13379 address argument is misaligned.
13381 2007-06-06 Vincent Celier <celier@adacore.com>
13383 * gnatcmd.adb (GNATCmd): Accept switch -aP for commands that accept

13390 All_Projects is True.
13391 (GNATCmd): Accept -U for GNAT LIST
13393 2007-06-06 Vincent Celier <celier@adacore.com>
13395 * gnatlink.adb (Gnatlink): Do not specify -static-libgcc when --LINK=
13397 Correct error message when invocation of the linker fails
13398 Add explicit size clause for the C imported variables
13399 Object_List_File_Supported and Using_GNU_Linker to emphasize that
13400 we expect char size.
13401 Read target parameters earlier, since this is needed to set
13402 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
13405 2007-06-06 Vincent Celier <celier@adacore.com>
13408 Add 3 spaces before the default project directory when displaying
13409 the project search path.

14889 parameter, rewrite the call as the indexing of a call with a single
14890 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
14892 (Resolve_Actuals): If an actual is an allocator for an access parameter,
14893 the master of the created object is the innermost enclosing statement.
14894 (Remove_Conversions): For a binary operator, check if type of second

14927 object of a null-excluding access type then don't require the
14928 the object declaration to have an expression and don't emit a

15058 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
15059 "abstract subprograms must be visible" message, whether or not the type
15060 is an interface; that is, remove the special case for interface types.

15087 Remove no longer used entities.
15089 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no

15137 attempt to derive from a synchronized tagged type.
15138 (Analyze_Type_Declaration): If there is a incomplete tagged view of the

15142 that use (a subtype of) the class-wide type of the enclosing type.
15143 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15144 Derived_Type for Prev formal on call to
15145 Check_Anonymous_Access_Components rather than Empty.
15146 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15147 a record extension in deciding whether to create a class-wide type,

15155 the associated_node for the itype is the type declaration itself.

15164 with abstract interfaces.

15201 gnatbind if the ALI file effectively exists.
15202 (Initialize): Add the directory where gnatmake is invoked in front of
15203 the path if it is invoked from a bin directory, even without directory
15204 information, so that the correct GNAT tools will be used when spawned
15205 without directory information.

15228 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15229 when -gnatg is not specified.
15230 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15231 there is no need to generate always a record_definition_node in case
15232 of synchronized interface types.
15233 (SIS_Entry_Active): Initialize global variable to False
15234 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to
15235 indicate cases where AI-447 says "not null" is legal.

15255 If the array component is a discriminated record, the array aggregate
15256 is non-static even if the component is given by an aggregate with
15258 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
15259 (Convert_Aggr_In_Allocator): If the allocator is for an access
15260 discriminant and the type is controlled. do not place on a finalization
15261 list at this point. The proper list will be determined from the
15263 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
15264 initialize record controller if needed, before the components, to ensure
15265 that they are properly finalized.
15266 (Build_Record_Aggr_Code): For the case of an array component that has a
15267 corresponding array aggregate in the record aggregate, perform sliding

15278 accessibility on class-wide allocators if the allocator occurs at the
15279 same scope level as the allocator's type. The check is guaranteed to
15280 succeed in that case, even when the expression originates from a
15281 parameter of the containing subprogram.
15282 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15283 under No_Dispatching_Calls restriction. During the semantic analysis
15284 we already notified such violation.
15285 (Tagged_Membership): Constant folding. There is no need to check
15286 the tag at run-time if the type of the right operand is non
15287 class-wide abstract.

15301 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
15302 initialize most the TSD components by means of an aggregate.
15303 Modify the declaration of the object containing the TSD
15304 because we now expand code that has a higher level of abstraction.
15305 The TSD has a discriminant containing the Inheritance Depth Level,
15306 value that is used in the membership test but also to fix the size
15307 of the table of ancestors.
15308 (Expand_Interface_Conversion): Insert function body at the closest place
15309 to the conversion expression, to prevent access-before-elaboration
15310 errors in the backend.

15312 compiling under restriction No_Dispatching_Calls plus code cleanup.
15313 Code reorganization plus removal of calls to Set_Num_Prim_Ops
15314 (Make_Secondary_DT): Remove call to Set_Num_Prim_Ops.

15335 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
15336 (Expand_Dispatching_Call): Replace generation of call to the run-time
15337 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15338 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15340 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15341 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
15342 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
15343 Build_Set_Prim_Op_Address.
15344 (Get_Remotely_Callable): Subprogram removed.
15345 (Init_Predefined_Interface_Primitives): Replace generation of call to
15346 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
15349 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15350 First (Parameter_Associations ()) with the call to First_Actual that
15351 returns an actual parameter expression for both named and positional
15354 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15355 check violation of restriction No_Dispatching_Calls.
15356 (Check_Controlling_Type): A formal of a tagged incomplete type is a
15357 controlling argument.

15360 First/Next_Component_Or_Discriminant
15361 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
15362 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15363 specify Any_Limited_Interface, and this functionality is already
15364 provided by the function Has_Abstract_Interfaces.
15365 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15366 support concurrent types implementing interfaces.
15367 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15368 specify kind Any_Limited_Interface, and this functionality is already
15369 provided by the function Has_Abstract_Interfaces.
15370 (Remove_Side_Effects): replace Controlled_Type by
15371 CW_Or_Controlled_Type whenever the issue is related to
15372 using or not the secondary stack.
15374 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
15375 P_Interface_Type_Definition to fulfill the new interface (the formal
15376 Is_Synchronized is no longer required).

15387 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
15388 anonymous, use finalization list of enclosing dynamic scope.
15389 (Expand_N_Package_Declaration): For a library package declaration
15390 without a corresponding body, generate RACW subprogram bodies in the
15391 spec (just as we do for the task activation call).
15392 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15393 Is_Abstract_Type. Make sure these are called only when appropriate.
15394 Remove all code for DSP option
15395 (CW_Or_Controlled_Type): new subprogram.

15401 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15402 parameter. If it is set to true, return a result capped according to
15403 the global upper bound for the index of an entry family.
15404 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
15405 (Build_Find_Body_Index): Adjust for above change.
15406 (Entry_Index_Expression): Likewise.

15411 Family_Size with 'Cap' set to true.
15412 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15413 a protected version of an operation declared in the private part of
15414 a protected object, because they may be invoked through a callback.
15415 (Set_Privals): If the type of a private component is an anonymous access
15416 type, do not create a new itype for each protected body.
15417 If the body of a protected operation creates
15418 controlled types (including allocators for class-widetypes), the
15419 body of the corresponding protected subprogram must include a
15421 (Build_Activation_Chain_Entity): Build the chain entity for extended
15423 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15424 to determine whether operation overrides an inherited primitive.
15425 (Build_Wrapper_Spec): Add code to examine the parents while looking
15426 for a possible overriding candidate.
15427 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15428 hold an actual parameter value since its initialization is separated
15429 from the the declaration. Prevents errors on null-excluding access

15433 Pablo Oliveira <oliveira@adacore.com>
15435 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15436 Do an Unchecked_Conversion to handle the passage from the Underlying

15438 Build_From_Any_Call.
15439 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15440 E_Constant, depending upon Variable formal.
15441 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15442 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15443 parameter that requires an extra constrained parameter, declare
15444 temporary for actual as a variable, not a constant.
15445 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15446 the unit being compiled is the one that contains the stub type.
15447 Change primitive operation name for the RACW associated with a RAS
15448 from Call to _Call so it cannot clash with any legal identifier.
15449 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15451 (Append_RACW_Bodies): New subprogram.
15452 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15453 Add_Receiving_Stubs_To_Declarations functions.
15454 When expanding a package body, this list correspond to the
15455 statements in the HSS at the end of the pacakge.
15456 When expanding a package spec, this list correspond to the

15459 registering the receiving stubs at the end of the 'Stmts' list.
15460 (RCI_Package_Locator): Pass the new Version generic formal when
15461 instantiating a RCI_Locator package.
15462 (Build_From_Any_Function): To compute the High bound for an
15463 unconstrained array actual, we add the Low bound with the length.
15464 Thus we must convert the low bound and the length to an appropriate
15465 type before doing the sum.
15466 (Build_Subprogram_Receiving_Stubs, PolyORB):
15467 * Retrieve the extra formals parameters at the
15468 end of the parameter stream.
15469 * Use Move_Any_Value to write back out parameters
15470 after executing the request as it is more efficient
15471 than Copy_Any_Value.
15472 * Build the any containing Extra Formals with the
15473 appropriate typecode.
15474 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15475 empty Component_List.
15476 (Build_Actual_Object_Declaration): New subprogram. Build and insert into

15488 function with the first not implicit parent type.
15489 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15490 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15491 typecode from the Etype. Therefore we retrieve the correct typecode
15492 with a call to Get_Any_Type.
15493 (Copy_Specification): Do controlling formal type substitution based on
15494 Is_Controlling_Formal flag, instead of caller-provided object type.
15495 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15496 a RACW primitive operation, we might get a subprogram declaration for an
15497 ancestor of the RACW designated type (not for the designated type
15498 itself), in the case where this operation is inherited. In this case we
15499 have no easy means of determining the original tagged type for which
15500 the primitive was declared, so instead we now rely on
15501 Copy_Specification to use the Is_Controlling_Formal flag to determine
15502 which formals require type substitution.

15510 handler unsuitable as a target for a local raise statement.
15511 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15512 run-time subprogram CW_Membership by call to Build_CW_Membership.
15513 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15514 by a function call, a temporary must be created before expanding the
15515 Constructor_Call itself, to prevent out-of-order elaboration in the
15516 back-end when stack checking is enabled..
15518 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15520 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15521 result are the bounds of the left operand, not the right.
15523 2007-04-06 Ed Schonberg <schonberg@adacore.com>

15643 * mingw32.h (S2WSU): New macro to convert from a string to a
15644 wide-string using the UTF-8 encoding. The S2WS macro supports now only
15645 standard 8bits encoding.
15646 (WS2SU): As above but converting from wide-sring to string.
15647 This is needed as it is necessary to have access to both versions in the
15648 runtime for the form parameter encoding support.
15649 This set of patch add support for the encoding form parameter.
15650 (S2WS): Improve implementation to handle cases where the filename is not
15651 UTF-8 encoded. In this case we default to using the current code page
15652 for the conversion.
15654 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
15655 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match
15656 the constants defined in adaint.h.
15657 (fopen): Add encoding parameter.
15660 * s-ficobl.ads (AFCB): Add Encoding field to record the filename
15661 encoding. This is needed for the Reset routine (freopen low level-call).

15699 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
15700 __gnat_adjust_context_for_raise.
15701 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
15702 implementation of floating point operations as native x86 targets.
15703 So the FPU should be initialized in the same way using finit. Fix
15704 floating point operations accuracy issues.
15705 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
15706 member in struct sigaction, so as to avoid warning for incompatible

15724 * lib-xref.ads, lib-xref.adb:
15725 Modify the loop that collects type references, to include interface
15726 types that the type implements. List each of these interfaces when
15727 building the entry for the type.
15728 (Generate_Definition): Initialize component Def and Typ of new entry
15729 in table Xrefs, to avoid to have these components unitialized.
15730 (Output_References): Split Is_Abstract flag into
15731 Is_Abstract_Subprogram and Is_Abstract_Type.
15732 (Generate_Reference): Add barrier to do not generate the warning
15733 associated with Ada 2005 entities with entities generated by the

15773 2007-04-06 Robert Dewar <dewar@adacore.com>
15775 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
15776 it no longer destroys the contents of Name_Buffer or Name_Len and
15777 non-standard and invalid names are handled better.
15778 (Get_Decoded_Name_String): Improve performance by using
15779 Name_Has_No_Encodings flag in the name table.
15780 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
15781 Used for debugging printouts.

15784 Javier Miranda <miranda@adacore.com>
15785 Bob Duff <duff@adacore.com>
15787 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
15788 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15789 there is no need to generate always a record_definition_node in case
15790 of synchronized interface types.
15791 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
15792 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
15793 illegal in Ada 95, in cases where it is legal. Change the warnings to
15794 errors in other cases. Don't give the error unless the "not null"
15795 parses properly. Correct the source position at which the error occurs.
15796 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
15797 P_Null_Exclusion, to suppress "not null" warnings.

15849 Entry for pragma Unreferenced_Objects
15851 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
15852 switches, without repetition of "eD". Make sure that last character of
15853 -gnatep= switch is not taken as -gnat switch character.
15854 Complete rewrite of circuit for handling saving compilation options
15855 Occasioned by need to support dot switchs for -gnatw, but cleans up

15873 the default project path, initially done during elaboration of the
15875 If the prefix returned by Sdefault is null, get the prefix from a call
15876 to Executable_Prefix_Path.
15877 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
15880 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
15881 canonical directory name to open the directory from which files are
15883 (Record_Other_Sources): Idem.
15884 (Locate_Directory): Add the possibility to create automatically missing
15885 directories when Setup_Projects is True.
15886 Call Locate_Directory so that the directory will be created when
15887 Setup_Projects is True, for object dir, library dir, library ALI dir,
15888 library source copy dir and exec dir.
15890 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
15893 2007-04-06 Robert Dewar <dewar@adacore.com>

15928 full word is no longer compared twice.
15930 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15932 * sem_ch10.adb (Install_Limited_Context_Clauses.
15933 Expand_Limited_With_Clause): Use a new copy of selector name in the
15934 call to Make_With_Clause. This fixes the tree structure for ASIS
15935 purposes. Nothing is changed in the compiler behaviour.
15936 (Process_Body_Clauses): Handle properly use clauses whose prefix is
15937 a package renaming.
15938 (Install_Limited_With_Clauses): Do not install non-limited view when it
15939 is still incomplete.
15941 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15942 Gary Dismukes <dismukes@adacore.com>
15944 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
15945 when capturing size information, instead of base type, which for a
15946 formal array type will be the unconstrained type.
15947 (Analyze_Formal_Object_Declaration): Add check for illegal default
15948 expressions for a formal in object of a limited type.
15949 (Instantiate_Object): Ditto.
15950 (Check_Formal_Package_Instance): Skip entities that are formal objects,
15951 because they were defaulted in the formal package and no check applies
15953 (Check_Formal_Package_Instance): Extend conformance check to other
15954 discrete types beyond Integer.
15955 (Process_Default): Copy directly the unmatched formal. A generic copy
15956 has already been performed in Analyze_Formal_Package.
15957 (Analyze_Associations): If a formal subprogram has no match, check for
15958 partial parametrization before looking for a default, to prevent
15960 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
15961 not set the instantiation environment before analyzing the actuals.
15962 Fixes regression on 8515-003 with implementation of AI-133.
15963 Set_Instance_Env checks whether the generic unit is a predefined
15964 unit, in which case the instance must be analyzed with the latest Ada
15965 mode. This setting must take place after analysis of the actuals,
15966 because the actuals must be analyzed and frozen in the Ada mode extant
15967 outside of the current instantiation.
15968 (Save_Env, Restore_Env): Preserve and restore the configuration
15969 parameters so that predefined units can be compiled in the proper Ada
15971 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
15972 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
15973 and Is_Abstract_Type.
15974 (Analyze_Formal_Package): For better error recovery, Add exception
15975 handler to catch Instantion_Error, which can be raised in
15976 Analyze_Associations
15978 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15979 Bob Duff <duff@adacore.com>
15980 Gary Dismukes <dismukes@adacore.com>
15982 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
15983 prefix type is a discriminated subtype of the type of the formal.
15984 (Analyze_Allocator): Collect all coextensions regardless of the context.
15985 Whether they can be allocated statically is determined in exp_ch4.
15986 (Analyze_Selected_Component): If the prefix is a limited view and the
15987 non-limited view is available, use the non-limited one.
15988 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
15989 therefore illegal), suggest a qualified expression rather than a type
15990 conversion, because a type conversion would be illegal in this context.
15991 (Anayze_Allocator): Trace recursively all nested allocators so that all
15992 coextensions are on the corresponding list for the root. Do no mark
15993 coextensions if the root allocator is within a declaration for a stack-
15994 allocated object, because the access discriminants will be allocated on
15996 (Analyze_Call): Remove restriction on calls to limited functions for the
15997 cases of generic actuals for formal objects, defaults for formal objects
15998 and defaults for record components.
15999 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16000 element list. Their expansion is delayed until the enclosing allocator
16001 is processed and its finalization list constructed.
16002 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16003 for an operation with the given name among the primitive operations of
16004 the corresponding record type.
16005 (Analyze_Selected_Component): If the prefix is a task type that
16006 implements an interface, and there is no entry with the given name,
16007 check whether there is another primitive operation (e.g. a function)
16009 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16010 properly the indexing of a function call written in prefix form, where
16011 the function returns an array type, and all parameters of the function
16012 except the first have defaults.
16013 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16014 the original operands, rather than relocating them, for efficiency and
16015 to work properly when an operand is overloaded.
16016 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16017 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16018 (Analyze_Selected_Component): If the prefix is a private extension, only
16019 scan the visible components, not those of the full view.
16020 (Try_Primitive_Operation): If the operation is a procedure, collect all
16021 possible interpretations, as for a function, because in the presence of
16022 classwide parameters several primitive operations of the type can match
16023 the given arguments.
16025 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16026 Robert Dewar <dewar@adacore.com>
16028 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a

16034 Thomas Quinot <quinot@adacore.com>
16036 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16037 out of Analyze_Package_Declaration, because processing must be applied
16038 to package bodies as well, for deferred constants completed by pragmas.
16039 (Analyze_Package_Declaration): When the package declaration being
16040 analyzed does not require an explicit body, call Check_Completion.
16041 (May_Need_Implicit_Body): An implicit body is required when a package
16042 spec contains the declaration of a remote access-to-classwide type.
16043 (Analyze_Package_Body): If the package contains RACWs, append the
16044 pending subprogram bodies generated by exp_dist at the end of the body.
16045 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16046 Is_Abstract_Subprogram and Is_Abstract_Type.
16047 (Preserve_Full_Attributes): The full entity list is not an attribute
16048 that must be preserved from full to partial view.
16050 * sem_dist.adb (Add_RAS_Dereference_TSS):
16051 Change primitive name to _Call so it cannot clash with any legal
16052 identifier, and be special-cased in Check_Completion.
16053 Mark the full view of the designated type for the RACW associated with
16054 a RAS as Comes_From_Source to get proper view switching when installing
16055 private declarations.
16056 Provite a placeholder nested package body along with the nested spec
16057 to have a place for Append_RACW_Bodies to generate the calling stubs
16058 and stream attributes.
16060 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16061 Robert Dewar <dewar@adacore.com>
16063 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16064 that is a limited view, check the non-limited view if available.
16065 (Undefined): Refine error message for missing with of Text_IO
16066 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16067 to distinguish real missing with cases.
16068 Fix format of all missing with messages
16069 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16070 renaming as body when renamed entity is abstract.
16072 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16073 Javier Miranda <miranda@adacore.com>
16075 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16076 predicate recursive, to handle complex expressions on literals whose
16077 spurious ambiguity comes from the abstract interpretation of some
16079 (Interface_Present_In_Ancestor): Add support to concurrent record
16081 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16082 Is_Abstract_Subprogram and Is_Abstract_Type.
16084 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16085 Javier Miranda <miranda@adacore.com>
16087 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16088 dereference of a local object R created as a reference to another
16089 object O, use the access level of O.
16090 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16091 rather than local Same_Formal_Type, to check whether protected operation
16092 overrides an inherited one.
16093 (Same_Formal_Type): New predicate, used when matching signatures of
16094 overriding synchronized operations, to handle the case when a formal
16095 has a type that is a generic actual.
16096 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16097 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16098 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16099 syntactic ambiguities involving indexing of function calls that return
16101 (Abstract_Interface_List): New subprogram that returns the list of
16102 abstract interfaces associated with a concurrent type or a
16103 concurrent record type.
16104 (Interface_Present_In_Parent): New subprogram used to check if a
16105 given type or some of its parents implement a given interface.
16106 (Collect_Abstract_Interfaces): Add support for concurrent types
16107 with interface types.
16108 (Has_Abstract_Interfaces): Add support for concurrent types with
16110 (Is_Parent): New subprogram that determines whether E1 is a parent
16111 of E2. For a concurrent type its parent is the first element of its

16113 same result than Is_Ancestor.
16114 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16115 (Collect_Synchronized_Interfaces): Removed because the subprogram
16116 Collect_Abstract_Interfaces provides this functionality.

16162 high bound is constant and the slice is empty. Tidy.
16163 (tree_transform, case N_Op_Not): Handle properly the case where the
16164 operation applies to a private type whose full view is a modular type.
16165 (Case_Statement_To_gnu): If an alternative is an E_Constant with an

16167 representing the choice value to ensure the corresponding GCC tree is
16168 of the proper kind.
16169 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16170 instead of just the operands, as the base GCC stabilize_reference does.
16171 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16172 requested; otherwise fail.
16173 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16453 anonymous access types.
16454 (Valid_Conversion): For a conversion to a numeric type occurring in an
16455 instance or inlined body, no need to check that the operand type is

17027 where discriminants may be used for the bounds of entry families.
17028 (Apply_Address_Clause_Check): Remove side-effects if address expression
17029 is non-static and is not the name of a declared constant.

17041 rewritten replacement for Apply_Alignment_Check
17042 (Get_E_Length/Get_E_First_Or_Last): Add missing barrier to ensure that
17043 we request a discriminal value only in case of discriminants.
17044 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17045 assignments where the target subtype is unconstrained and the target
17046 object is a parameter or dereference (other aliased cases are known
17047 to be unconstrained).
17049 2006-10-31 Robert Dewar <dewar@adacore.com>

17127 Make use of concatenation now allowed in compiler
17128 (Executable_Prefix.Get_Install_Dir): First get the full path, so that
17129 we find the 'lib' or 'bin' directory even when the tool has been
17130 invoked with a relative path.

17133 * osint-c.ads, osint-c.adb:
17134 Implement new -gnatl=xxx switch to output listing to file

17161 the parent part is a build-in-place function call, generate assignments.
17162 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17163 are build-in-place function calls.
17164 (Replace_Self_Reference): New subsidiary of
17165 Make_OK_Assignment_Statement, to replace an access attribute that is a
17166 self-reference into an access to the appropriate component of the
17167 target object. Generalizes previous mechanism to handle self-references
17168 nested at any level.
17169 (Is_Self_Referential_Init): Remove, not needed.
17170 (Is_Self_Referential_Init): New predicate to simplify handling of self
17171 referential components in record aggregates.

17173 check for presence of entity before checking for self-reference.
17174 (Has_Default_Init_Comps): Return True if a component association is a
17175 self-reference to the enclosing type, which can only come from a
17176 default initialization.
17177 (Make_OK_Assignment_Statement): If the expression is of the form
17178 Typ'Acc, where Acc is an access attribute, the expression comes from a
17179 default initialized self-referential component.
17180 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17181 that has been derived from several abstract interfaces we must also
17182 initialize the tags of the secondary dispatch tables.

17185 Thomas Quinot <quinot@adacore.com>
17186 Javier Miranda <miranda@adacore.com>
17187 Robert Dewar <dewar@adacore.com>
17190 (Expand_Access_To_Protected_Op): If the context indicates that an access
17191 to a local operation may be transfered outside of the object, create an
17192 access to the wrapper operation that must be used in an external call.
17193 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17194 target, pass the Valid attribute applied to a floating-point prefix on
17195 to the back end without expansion.
17196 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17197 the allocated storage when it is specified by a per-object expression.
17198 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17199 Nothing to do here, the attribute has been rewritten during semantic

17203 (Find_Fat_Info): Handle case of universal real
17204 (Expand_Access_To_Protected_Op): Fix use of access to protected
17205 subprogram from inside the body of a protected entry.

17208 into a fat pointer.
17209 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17210 subcomponent's enclosing variable is aliased with a constrained subtype.
17211 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17212 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17213 an aliased prefix must be known to be constrained in order to use True
17214 for the attribute value, and now it's possible for some aliased views
17215 to be unconstrained.
17217 2006-10-31 Robert Dewar <dewar@adacore.com>
17219 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17220 (Expand_Entity_Reference): Correct error of not handling subprogram
17221 formals in current_value processing.
17223 2006-10-31 Javier Miranda <miranda@adacore.com>
17224 Robert Dewar <dewar@adacore.com>
17225 Ed Schonberg <schonberg@adacore.com>
17226 Gary Dismukes <dismukes@adacore.com>
17228 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17229 register in the final list objects containing class-wide interfaces;
17230 otherwise we incorrectly register the tag of the interface in the final
17232 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17233 generate the wrapper if the parent primitive is abstract. This is
17234 required to report the correct error message.
17235 (Expand_N_Subtype_Indication): Do validity checks on range
17236 (Clean_Task_Names): If an initialization procedure includes a call to
17237 initialize a task (sub)component, indicate that the procedure will use
17238 the secondary stack.
17239 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17240 compatibility for interfacing with CPP by default.
17241 (Expand_N_Object_Declaration): Only build an Adjust call when the
17242 object's type is a nonlimited controlled type.
17243 * exp_ch3.adb: Add with and use of Exp_Ch6.
17244 (Expand_N_Object_Declaration): Check for object initialization that is a
17245 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17246 Object_Declaration to the call.
17247 (Freeze_Type): When the designated type of an RACW was not frozen at the
17248 point where the RACW was declared, validate the primitive operations
17249 with respect to E.2.2(14) when it finally is frozen.
17250 (Build_Initialization_Call,Expand_Record_Controller): Rename
17251 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17252 return-by-reference has no meaning in Ada 2005.
17253 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17254 to register tag of the immediate ancestor interfaces in the
17255 run-time structure.
17256 (Init_Secondary_Tags): Moved to the specification to allow the
17257 initialization of extension aggregates with abstract interfaces.
17258 (Build_Master_Renaming): Make public, for use by function declarations
17259 whose return type is an anonymous access type.
17260 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17261 Insert_List_Before_And_Analyze after the generation of the specs
17262 associated with null procedures.
17263 (Expand_Tagged_Root): Update documentation in its specification.
17264 (Init_Secondary_Tags): Update documentation.
17265 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17266 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17267 then generate code to inherit the contents of the dispatch table
17268 directly from the ancestor.
17269 (Expand_Record_Controller): Insert controller component after tags of
17270 implemented interfaces.
17271 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17272 create null procedure overridings when null procedures are inherited
17274 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17275 declarations for overriding null primitives inherited from interfaces.
17276 (Is_Null_Interface_Procedure): New function in
17277 Make_Null_Procedure_Specs.
17278 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17279 immediate ancestor of a tagged type is an abstract interface type we
17280 must generate the specification of the predefined primitives associated
17281 with controlled types (because the dispatch table of the ancestor is
17282 null and hence these entries cannot be inherited). This is required to
17283 elaborate well the dispatch table.

17293 (Expand_N_In): Do validity checks on range
17294 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17295 (Expand_N_Allocator): For "new T", if the object is constrained by
17296 discriminant defaults, allocate the right amount of memory, rather than
17297 the maximum for type T.
17298 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17299 when the allocator is initialized by a build-in-place call, since the
17300 allocator is already rewritten as a reference to the function result,
17301 and this prevents an unwanted duplication of the function call.
17302 Add with and use of Exp_Ch6.
17303 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17304 is a call to build-in-place function and apply
17305 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17306 untagged designated types).
17307 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17308 optimization if source or target is biased.
17309 (Expand_N_Allocator): Add comments for case of an allocator within a
17310 function that returns an anonymous access type designating tasks.
17311 (Expand_N_Allocator): apply discriminant checks for access
17312 discriminants of anonymous access types (AI-402, AI-416)
17314 2006-10-31 Bob Duff <duff@adacore.com>
17315 Robert Dewar <dewar@adacore.com>

17317 Ed Schonberg <schonberg@adacore.com>
17319 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17321 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17322 (Expand_N_Assignment_Statement): Call
17323 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17324 build-in-place function call. Currently, this can happen only for
17325 assignments that come from aggregates.
17326 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17327 in order to alleviate the upward compatibility introduced by AI-318.
17328 (Expand_N_Extended_Return_Statement): Add support for handling the
17329 return object as a build-in-place result.
17330 (Expand_Non_Function_Return): Implement simple return statements nested
17331 within an extended return.
17332 (Enable_New_Return_Processing): Turn on the new processing of return
17334 (Expand_Non_Function_Return): For a return within an extended return,
17335 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17336 (Expand_N_Extended_Return_Statement): Implement AI-318
17337 (Expand_Simple_Function_Return): Ditto.
17338 (Expand_N_If_Statement): Handle new -gnatwt warning
17339 (Expand_N_Case_Statement): Handle new -gnatwt warning
17340 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17341 a protected object.
17342 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17343 validity checking of assignments to elementary record components.
17344 (Expand_N_Return_Statement): return Class Wide types on the secondary
17345 stack independantly of their controlled status since with HIE runtimes,
17346 class wide types are not potentially controlled anymore.
17348 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17351 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17352 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17353 it expects a block, procedure, or task. The return statement will get
17354 turned into a block, and Expand_Cleanup_Actions will happen then.
17356 2006-10-31 Robert Dewar <dewar@adacore.com>
17357 Ed Schonberg <schonberg@adacore.com>
17358 Bob Duff <duff@adacore.com>
17359 Gary Dismukes <dismukes@adacore.com>
17361 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17363 (Expand_Inlined_Call): Tagged types are by-reference types, and
17364 therefore should be replaced by a renaming declaration in the expanded
17365 body, as is done for limited types.
17366 (Expand_Call): If this is a call to a function with dispatching access
17367 result, propagate tag from context.
17368 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17370 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17371 build-in-place when the right-hand side of an assignment is a
17372 build-in-place function call.
17373 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17374 of the explicit dereference of the allocator to the result subtype of
17375 the build-in-place function. This is needed to satisfy type checking
17376 in cases where the caller's return object is created by an allocator for
17377 a class-wide access type and the type named in the allocator is a
17379 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17380 conversion of the reference to the declared object to the result subtype
17381 of the build-in-place function. This is needed to satisfy type checking
17382 in cases where the declared object has a class-wide type. Also, in the
17383 class-wide case, change the type of the object entity to the specific
17384 result subtype of the function, to avoid passing a class-wide object
17385 without explicit initialization to the back end.
17386 (Register_Interface_DT_Entry): Moved outside the body of
17387 Freeze_Subprogram because this routine is now public; it is called from
17388 Check_Dispatching_Overriding to handle late overriding of abstract
17389 interface primitives.
17390 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17391 adding an implicit access actual on a call to a build-in-place function.
17392 (Expand_Actuals): Test for an actual parameter that is a call to a
17393 build-in-place function and apply
17394 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17395 (Is_Build_In_Place_Function): New function to determine whether an
17396 entity is a function whose calls should be handled as build-in-place.
17397 (Is_Build_In_Place_Function_Call): New function to determine whether an
17398 expression is a function call that should handled as build-in-place.
17399 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17400 calls to build-in-place functions as the initialization of an allocator.
17401 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17402 handling calls to build-in-place functions in contexts that do not
17403 involve init of a separate object (for example, actuals of subprogram
17405 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17406 handling calls to build-in-place functions as the initialization of an
17407 object declaration.
17408 (Detect_Infinite_Recursion): Add explicit parameter Process to
17409 instantiation of Traverse_Body to avoid unreferenced warning.
17410 (Check_Overriding_Inherited_Interfaces): Removed.
17411 (Register_Interface_DT_Entry): Code cleanup.
17412 (Register_Predefined_DT_Entry): Code cleanup.
17413 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17414 inlined statements if within a transient scope.
17415 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17416 formal parameters with occurrences of actuals in inlined body, establish
17417 visibility on the proper view of the actual's subtype for the body's
17419 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17420 compatibility mode and we have an imported CPP subprogram because
17421 for now we assume that imported CPP primitives correspond with
17422 objects whose constructor is in the CPP side (and therefore we
17423 don't need to generate code to register them in the dispatch table).
17424 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17425 aligned selected component.
17426 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17427 the actual of an in-mode parameter is a type conversion.
17428 (Expand_Actuals): If the call does not come from source and the actual
17429 is potentially misaligned, let gigi handle it rather than rejecting the
17430 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17431 Class Wide types as returning by reference independantly of their
17432 controlled status since with HIE runtimes class wide types are not
17433 potentially controlled anymore.
17435 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17437 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17438 references that are private components of the protected object.

17449 initialization of Homonym_Len.
17450 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17451 names from fully qualified name. Fixes problem of duplicate

17455 Pablo Oliveira <oliveira@adacore.com>
17457 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17458 subprogram Ids, even if they are not yet assigned.
17459 (Build_Subprogram_Id): It is now this function that will take care of
17460 calling Assign_Subprogram_Ids if necessary.
17461 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17462 should be done only once they are assigned.
17463 (Build_From_Any_Function, case of tagged types): Add missing call to
17465 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17466 type for an RACW type.
17467 (Add_RACW_Features): When processing an RACW declaration for which the
17468 designated type is already frozen, enforce E.2.2(14) rules immediately.
17469 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17470 special reordering of controlling formals.
17472 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17473 associated stub type for an RACW type.
17475 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17477 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17478 fixed-point operations in an integer context, i.e. as operands of a
17479 conversion to an integer type, indicate that result must be rounded.
17481 2006-10-31 Robert Dewar <dewar@adacore.com>
17483 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17484 cases, pass the encoding method, since it is now required by the run
17487 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17488 assumption that Str'First = 1.
17489 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17490 it on to the Value_Wide_Wide_Character call.
17491 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17492 properly handles a string of the form quote-encoded_wide_char-quote.
17494 * s-wchcnv.adb: Minor reformatting
17496 2006-10-31 Javier Miranda <miranda@adacore.com>
17498 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17499 run-time membership test to ensure that the constructed object
17500 implements the target abstract interface.
17502 2006-10-31 Robert Dewar <dewar@adacore.com>
17504 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17505 Machine_Attribute pragma internally to implement the user pragma.
17506 Add processing for pragma Interface so that it is now completely
17507 equivalent to pragma Import.
17509 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17510 so that it can be applied to all entities, including record components
17511 and enumeration literals.
17512 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17513 priority ranges are correct, verify compatibility against task
17514 dispatching and locking policies, and if everything is correct an entry
17515 is added to the table containing priority specific dispatching entries
17516 for this compilation unit.
17517 (Delay_Config_Pragma_Analyze): Delay processing
17518 Priority_Specific_Dispatching pragmas because when processing the
17519 pragma we need to access run-time data, such as the range of
17520 System.Any_Priority.
17521 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17522 Allow pragma Unreferenced as a context item
17523 Add pragma Preelaborable_Initialization
17524 (Analyze_Pragma, case Interface): Interface is extended so that it is
17525 now syntactically and semantically equivalent to Import.
17526 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17527 insertion characters.
17528 Add handling for Pragma_Wide_Character_Encoding
17529 (Process_Restrictions_Restriction_Warnings): Ensure that a warning

17531 always supercedes a warning.
17532 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17539 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17540 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17541 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17543 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17544 type of the function containing a return statement, because the
17545 Return_Type field was removed. We now use the Return_Applies_To field.
17547 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17548 (Build_Task_Image_Decl): If procedure is not called from an
17549 initialization procedure, indicate that function that builds task name
17550 uses the sec. stack. Otherwise the enclosing initialization procedure
17551 will carry the indication.
17552 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17553 N_Object_Declaration instead.
17554 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17555 conditional dead code killed, and change implementation accordingly.
17556 (Insert_Actions): Add N_Return_Object_Declaration case.
17557 Correct comment to mention N_Extension_Aggregate node.
17558 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17559 attempts to save information for global variables which cannot be
17561 (Get_Current_Value_Condition): Handle conditions the other way round
17562 (constant on left). Also handle right operand of AND and AND THEN
17563 (Set_Current_Value_Condition): Corresponding changes
17564 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17565 (Get_Current_Value_Condition): Handle simple boolean operands
17566 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17567 (Get_Current_Value_Condition): If the variable reference is within an
17568 if-statement, does not appear in the list of then_statments, and does
17569 not come from source, treat it as being at unknown location.
17570 (Get_Current_Value_Condition): Enhance to allow while statements to be
17571 processed as well as if statements.
17572 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17574 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17575 of loop. This is safe now that we fixed Kill_Current_Values.
17576 (OK_To_Do_Constant_Replacement): Check whether current scope is
17577 Standard, before examining outer scopes.
17579 2006-10-31 Vincent Celier <celier@adacore.com>

17592 (Freeze_Entity): Add check for Preelaborable_Initialization
17594 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17596 * g-expect.adb: Add Warnings (Off) to prevent new warning
17598 * lib-xref.adb: Add handling of Last_Assignment field
17599 (Generate_Reference): Centralize handling of pragma Obsolescent here
17600 (Generate_Reference): Accept an implicit reference generated for a
17601 default in an instance.
17602 (Generate_Reference): Accept a reference for a node that is not in the
17603 main unit, if it is the generic body corresponding to an subprogram
17606 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17608 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17610 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17612 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17613 use clauses, to avoid messages on packages used to qualify, and also
17614 to avoid messages from obsolescent units.
17615 (Warn_On_Useless_Assignments): Don't generate messages for imported
17616 and exported variables.
17617 (Warn_On_Useless_Assignments): New procedure
17618 (Output_Obsolescent_Entity_Warnings): New procedure
17619 (Check_Code_Statement): New procedure

17623 (Last_Assignment): New field for useless assignment warning
17625 2006-10-31 Olivier Hainque <hainque@adacore.com>
17627 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17628 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17630 2006-10-31 Bob Duff <duff@adacore.com>
17631 Robert Dewar <dewar@adacore.com>
17632 Ed Schonberg <schonberg@adacore.com>
17634 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17635 Ada 95 mode, because it violates the new rules for AI-318.
17637 * g-awk.ads: Use overloaded subprograms in every case where we used to
17638 have a default of Current_Session. This makes the code closer to be
17639 correct for both Ada 95 and 2005.
17641 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17642 code, relying on the fact that the compiler generates a warning
17643 instead of an error in -gnatg mode.
17645 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17646 E_Return_Statement entity kind.
17647 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17649 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17650 report an error if the reserved word abstract has been previously found.
17651 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17653 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17654 parenthesized range attribute usage
17655 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17657 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17658 in the syntax for extended_return_statement. This is not in the latest
17659 RM, but the ARG is expected to issue an AI allowing this.
17660 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17661 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17662 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17663 P_Return_Statement): Parse the new syntax for extended_return_statement.
17665 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17666 Output_End_Missing): Add error-recovery code for the new
17667 extended_return_statement syntax; that is, the new E_Return entry on
17670 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17671 limited to nonlimited, because otherwise we violate the new Ada 2005
17672 rules about returning limited types in function Create_AST_Handler in
17675 * sem.adb (Analyze): Add cases for new node kinds
17676 N_Extended_Return_Statement and N_Return_Object_Declaration.
17678 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17679 type is in the same category as type of context before applying check,
17680 to prevent anomalies in instantiations.
17681 (Resolve_Aggregate): Remove test for limited components in aggregates.
17682 It's unnecessary in Ada 95, because if it has limited components, then
17683 it must be limited. It's wrong in Ada 2005, because limited aggregates
17685 (Resolve_Record_Aggregate): Move check for limited types later, because
17686 OK_For_Limited_Init requires its argument to have been resolved.
17687 (Get_Value): When copying the component default expression for a
17688 defaulted association in an aggregate, use the sloc of the aggregate
17689 and not that of the original expression, to prevent spurious
17690 elaboration errors, when the expression includes function calls.
17691 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17692 were missing. We also didn't handle qualified expressions. Now also
17693 allow function calls. Use new common routine OK_For_Limited_Init.
17694 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17695 with space can upper case letter).
17697 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17698 Has_Static_Discriminants flag
17699 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17700 type with discriminants.
17701 (Process_Range_Expr_In_Decl): Do validity checks on range
17702 (Build_Discriminant_Constraints): Use updated form of
17703 Denotes_Discriminant.
17704 (Process_Subtype): If the subtype is a private subtype whose full view
17705 is a concurrent subtype, introduce an itype reference to prevent scope
17707 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17708 Record_Type_Declaration): The functionality of the subprograms
17709 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17710 is now performed by a single routine.
17711 (Build_Derived_Record_Type): If the type definition includes an explicit
17712 indication of limitedness, then the type must be marked as limited here
17713 to ensure that any access discriminants will not be treated as having
17714 a local anonymous access type.
17715 (Check_Abstract_Overriding): Issue a detailed error message when an
17716 abstract subprogram was not overridden due to incorrect mode of its
17718 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17719 synchronized private extension declarations. Verify that the ancestor is
17720 a limited or synchronized interface or in the generic case, the ancestor
17721 is a tagged limited type or synchronized interface and all progenitors
17722 are either limited or synchronized interfaces.
17723 Derived_Type_Declaration): Check for presence of private extension when
17724 dealing with synchronized formal derived types.
17725 Process_Full_View): Enchance the check done on the usage of "limited" by
17726 testing whether the private view is synchronized.
17727 Verify that a synchronized private view is completed by a protected or
17729 (OK_For_Limited_Init_In_05): New function.
17730 (Analyze_Object_Declaration): Move check for limited types later,
17731 because OK_For_Limited_Init requires its argument to have been resolved.
17732 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17733 in order to alleviate the upward compatibility introduced by AI-318.
17734 (Constrain_Corresponding_Record): If the constraint is for a component
17735 subtype, mark the itype as frozen, to avoid out-of-scope references to
17736 discriminants in the back-end.
17737 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17738 this subprogram against wrong sources.
17739 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17740 discriminant of limited type completed with a protected type, when the
17741 discriminant is used to constrain a private component of the type, and
17742 expansion is disabled.
17743 (Find_Type_Of_Object): Do not treat a return subtype that is an
17744 anonymous subtype as a local_anonymous_type, because its accessibility
17745 level is the return type of the enclosing function.
17746 (Check_Initialization): In -gnatg mode, turn the error "cannot
17747 initialize entities of limited type" into a warning.
17748 (OK_For_Limited_Init): Return true for generated nodes, since it
17749 sometimes violates the legality rules.
17750 (Make_Incomplete_Declaration): If the type for which an incomplete
17751 declaration is created happens to be the currently visible entity,
17752 preserve the homonym chain when removing it from visibility.
17753 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17754 inherited subprograms.
17755 (Access_Definition): If this is an access to function that is the return
17756 type of an access_to_function definition, context is a type declaration
17757 and the scope of the anonymous type is the current one.
17758 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17759 incomplete subtype to the set of private dependents of the original
17761 (Constrain_Discriminated_Type): Emit an error message whenever an
17762 incomplete subtype is being constrained.
17763 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17764 corresponding subtype of the full view of the original incomplete type.
17765 (Check_Incomplete): Properly detect invalid usage of incomplete types
17768 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
17770 * g-catiio.ads, g-catiio.adb (Value): New function.

17779 Robert Dewar <dewar@adacore.com>
17781 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
17782 handling executable extension manually and duplicating code.
17784 * make.adb: Implement new -S switch
17785 (Gnatmake): Use new function Osint.Executable_Name instead
17786 of handling executable extension manually.
17788 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
17789 is specified, the executable name ends with this suffix.
17790 Take advantage of Osint.Executable_Name instead of duplicating code.
17792 * switch-m.adb: Recognize new gnatmake -S switch
17794 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
17796 (Get_Target_Parameters): Set Executable_Extension_On_Target if
17799 * makeusg.adb: Add line for gnatmake -S switch
17801 2006-10-31 Vincent Celier <celier@adacore.com>
17803 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17804 call it with -static-libgcc, as there are some platforms, such as
17805 Darwin, where one of these two switches is compulsory to link.
17807 2006-10-31 Vincent Celier <celier@adacore.com>
17809 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17810 instead of ADA_PROJECT_PATH, for the project path.
17811 (Gnatls): When displaying the project path directories, use host dir
17814 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17815 names in the project path, as absolute paths may correspond to
17816 multi-valued VMS logical names.
17818 2006-10-31 Vincent Celier <celier@adacore.com>
17820 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
17821 absolute path name.
17822 (Locate_Regular_File): Ditto
17823 (Change_Dir): Remove, no longer used
17824 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
17825 on Windows. Get it calling Get_Current_Dir.
17826 (OpenVMS): Remove imported boolean, no longer needed.
17827 (Normalize_Pathname)[VMS]: Do not resolve directory names.
17828 (Pid_To_Integer): New function to convert a Process_Id to Integer
17830 2006-10-31 Thomas Quinot <quinot@adacore.com>
17832 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
17833 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
17835 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
17838 2006-10-31 Robert Dewar <dewar@adacore.com>
17840 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
17841 initial letter o as a zero.

17847 2006-10-31 Robert Dewar <dewar@adacore.com>
17849 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
17851 (Layout_Variant_Record): Retrieve the discriminants from the entity
17852 rather than from the type definition, because in the case of a full
17853 type for a private type we need to take the discriminants from the
17855 (Layout_Component_List): When applying the Max operator to variants with
17856 a nonstatic size, check whether either operand is static and scale that
17857 operand from bits to storage units before applying Max.
17858 (Layout_Type): In VMS, if a C-convention access type has no explicit
17859 size clause (and does not inherit one in the case of a derived type),
17860 then the size is reset to 32 from 64.
17862 2006-10-31 Vincent Celier <celier@adacore.com>
17864 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
17865 its file has already been loaded, according to the unit being loaded,
17866 not to the current value of Multiple_Unit_Index.
17868 2006-10-31 Thomas Quinot <quinot@adacore.com>
17869 Eric Botcazou <ebotcazou@adacore.com>
17870 Arnaud Charlet <charlet@adacore.com>

17876 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
17877 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
17878 a-calend-mingw.adb version.
17880 * Makefile.rtl: Added s-dsaser.
17881 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
17882 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
17883 Ada.Dispatching.Round_Robin.
17884 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
17886 * Make-lang.in: Remove all references to gt-ada-decl.h.
17887 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler

17892 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
17894 2006-10-31 Vincent Celier <celier@adacore.com>
17896 * mlib-utl.adb (Initialized): Remove, no longer used
17897 (Initialize): Remove, no longer used
17898 (Ar): If Ar_Exec is null, get the location of the archive builder and,
17899 if there is one, the archive indexer. Fail if the archive builder cannot
17901 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
17904 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17906 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
17907 Process_Body_Clauses): If the context of a body includes a use clause
17908 for P.Q then a with_clause for P in the same body is not redundant,
17909 even if the spec also has a with_clause on P.
17910 Add missing continuation mark to error msg
17911 (Build_Limited_Views): A limited view of a type is tagged if its
17912 declaration includes a record extension.
17913 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
17914 node, even if the subunit has errors. This avoids malfunction by
17915 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
17916 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
17917 generation of obsolescent messages for with statements (cannot do
17918 this too early, or we cannot implement avoiding the messages in the
17919 case of obsolescent units withing obsolescent units).
17920 (Install_Siblings): If the with_clause is on a remote descendant of
17921 an ancestor of the current compilation unit, find whether there is
17922 a sibling child unit that is immediately visible.
17923 (Remove_Private_With_Clauses): New procedure, invoked after completing
17924 the analysis of the private part of a nested package, to remove from
17925 visibility the private with_clauses of the enclosing package
17927 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
17928 now centralized in Generate_Reference.
17929 (Install_Limited_Context_Clauses): Remove superfluous error
17930 message associated with unlimited view visible through use
17931 and renamings. In addition, at the point in which the error
17932 is reported, we add the backslash to the text of the error
17933 to ensure that it is reported as a single error message.
17934 Use new // insertion for some continuation messages
17935 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
17936 to create implicit with_clause for parent unit mentioned in original
17937 limited_with_clause.
17938 (Install_Limited_With_Unit): Set entity of parent identifiers if the
17939 unit is a child unit. For ASIS queries.
17940 (Analyze_Subunit): If the subunit appears within a child unit, make all
17941 ancestor child units directly visible again.

17951 (P_Formal_Type_Definition, P_Formal_Derived_Type_Definition): Add
17952 support for synchronized derived type definitions.
17953 Add the new actual Abstract_Present to every call to
17954 P_Interface_Type_Definition.
17955 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
17956 a formal object declaration with an access definition or a subtype mark
17957 with a null exclusion.
17958 (P_Generic_Association): Handle association with box, and others_choice
17959 with box, to support Ada 2005 partially parametrized formal packages.
17961 2006-10-31 Robert Dewar <dewar@adacore.com>
17962 Javier Miranda <miranda@adacore.com>
17964 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
17965 (P_Type_Declaration): Remove barrier against the reserved word "limited"
17966 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
17967 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
17968 private extensions.
17969 (P_Type_Declaration): Add the new actual Abstract_Present to every call
17970 to P_Interface_Type_Definition.
17971 (P_Interface_Type_Definition): Addition of one formal to report an error
17972 if the reserved word abstract has been previously found.
17973 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
17974 object renaming declaration with an access definition or subtype mark
17975 with a possible null exclusion.
17977 * par-ch9.adb: Minor error msg fix
17979 * par-load.adb: Add missing continuation mark to error msg
17981 * par-tchk.adb: (Wrong_Token): Code cleanup, use concatenation
17983 2006-10-31 Vincent Celier <celier@adacore.com>

17991 2006-10-31 Vincent Celier <celier@adacore.com>
17993 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
17994 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
17997 2006-10-31 Vincent Celier <celier@adacore.com>
17999 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18000 on VMS, change "__" to '.' before checking the name.
18001 (Record_Ada_Source): Always add the source file name in the list of
18002 of sources, even if it is not the first time, as it is for another
18004 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18005 dot, instead of replacing only the first '_'.
18007 * prj-part.adb (Parse): Convert project file path to canonical form
18009 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18010 extended, the project id of the project extending it is recorded in its
18011 data, even when it has already been processed as an imported project.
18013 2006-10-31 Robert Dewar <dewar@adacore.com>
18015 * repinfo.adb (List_Entities): Don't list entities from renaming
18018 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18019 Robert Dewar <dewar@adacore.com>
18021 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18022 only a restriction warning is active for the given restriction. This is
18023 desirable because we do not want to modify code in the case where only
18025 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18026 causes overriding of real restrictions.
18027 Take advantage of new No_Restrictions constant.
18029 * raise.h: (__gnat_set_globals): Change profile.
18031 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18033 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18036 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18037 Move all the entities in obsolete package System.PolyORB_Interface to
18038 System.Partition_Interface.
18039 (RE_Storage_Size): New function in System.Tasking.
18040 (RE_Get_Ceiling): New entity.

18052 Thomas Quinot <quinot@adacore.com>
18053 Javier Miranda <miranda@adacore.com>
18054 Gary Dismukes <dismukes@adacore.com>
18056 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18057 properly an attempt to apply Unchecked_Access to a protected operation.
18058 (OK_Self_Reference): New subprogram to check the legality of an access
18059 attribute whose prefix is the type of an enclosing aggregate.
18060 Generalizes previous mechanism to handle attribute references nested
18061 arbitrarily deep within the aggregate.
18062 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18063 can appear in an aggregate if this is a default-initialized aggregate
18064 for a self-referential type.
18065 (Resolve_Attribute, case Access): Ditto.
18066 Add support for new implementation defined attribute Stub_Type.
18067 (Eval_Attribute, case Attribute_Stub_Type): New case.
18068 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18069 (Stream_Attribute_Available): Implement using new subprogram from
18070 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18071 Has_Specified_Stream_Attribute flag.
18072 Disallow Storage_Size and Storage_Pool for access to subprogram
18073 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18074 access types of return subtypes in extended return statements. Remove
18075 accessibility checks on anonymous access types when Unchecked_Access is
18077 (Analyze_Attribute): Add support for the use of 'Class to convert
18078 a class-wide interface to a tagged type.
18079 Add support for the attribute Priority.
18080 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18081 whether the designated type is discriminated with a constrained partial
18082 view and require static matching in that case.
18083 Add local variable Des_Btyp. The Designated_Type
18084 of an access to incomplete subtype is either its non-limited view if
18085 coming from a limited with or its etype if regular incomplete subtype.
18087 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18088 Fix predicate to identify and allow cases of (expander-generated)
18089 references to tag of designated object of a RACW.
18090 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18091 non-static, and therefore cannot appear as a primary in a preelaborable
18093 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18094 Has_Read_Write_Attributes.
18095 (Has_Read_Write_Attributes): Reimplement in termes of
18096 Has_Stream_Attribute_Definition.
18097 (Missing_Read_Write_Attributes): When checking component types in a
18098 record, unconditionally call Missing_Read_Write_Attributes recursively
18099 (remove guard checking for Is_Record_Type / Is_Access_Type).
18101 2006-10-31 Robert Dewar <dewar@adacore.com>
18103 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18104 useless assignments here and conditionalize it on absence of exception
18106 (Analyze_Exception_Handlers): Small code reorganization of error
18107 detection code, for new handling of formal packages.
18109 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18110 Hristian Kirtchev <kirtchev@adacore.com>
18112 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18113 that has been constant-folded, preserve information of original tree,
18115 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18116 generated private extension declaration if the formal derived type is
18117 synchronized. Carry synchronized present over to the generated private
18119 (Validate_Derived_Type_Instance): Ensure that the actual of a
18120 synchronized formal derived type is a synchronized tagged type.
18121 (Instantiate_Formal_Package): When creating the instantiation used to
18122 validate the actual package of a formal declared without a box, check
18123 whether the formal itself depends on a prior actual.
18124 (Instantiate_Formal_Subprogram): Create new entities for the defining
18125 identifiers of the formals in the renaming declaration, for ASIS use.
18126 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18127 a renaming declaration or a subtype declaration for an actual in an
18128 instance, capture location information of declaration in generic, for
18130 (Instantiate_Formal_Package): Add comments on needed additional tests.
18131 AI-317 (partial parametrization) is fully implemented.
18132 (Validate_Private_Type_Instance): Add check for actual which
18133 must have preelaborable initialization
18134 Use new // insertion for some continuation messages
18135 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18136 Default_Expression. Add type retrieval when the declaration has an
18137 access definition. Update premature usage of incomplete type check.
18138 (Check_Access_Definition): New subsidiary routine. Check whether the
18139 current compilation version is Ada 05 and the supplied node has an
18141 (Instantiate object): Alphabetize local variables. Handle the creation
18142 of new renaming declarations with respect to the kind of definition
18143 used - either an access definition or a subtype mark. Guard against
18144 unnecessary error message in the context of anonymous access types after
18145 they have been resolved. Add check for required null exclusion in a
18146 formal object declaration.
18147 (Switch_View): A private subtype of a non-private type needs to be
18148 switched (the base type can have been switched without its private
18149 dependents because of the last branch of Check_Private_View.
18150 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18152 (Instantiate_Type): Emit an error message whenever a class-wide type of
18153 a tagged incomplete type is used as a generic actual.
18154 (Find_Actual_Type): Extend routine to handle a component type in a child
18155 unit that is imported from a formal package in a parent.
18156 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18157 agree on constrainedness, rather than checking against ultimate ancestor
18158 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18159 generic body, for navigation purposes.
18161 2006-10-31 Robert Dewar <dewar@adacore.com>
18162 Thomas Quinot <quinot@adacore.com>
18164 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18166 (New_Stream_Subprogram): When processing an attribute definition clause
18167 for a stream-oriented subprogram, record an entity node occurring at
18168 the point of clause to use for checking the visibility of the clause,
18169 as defined by 8.3(23) as amended by AI-195.
18170 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18171 New_Stream_Function and New_Stream_Procedure.
18172 (New_Stream_Function, New_Stream_Procedure): Removed.
18173 (Analyze_Attribute_Definition_Clause, case Address): Check new
18174 Alignment_Check check
18176 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18177 Javier Miranda <miranda@adacore.com>
18178 Robert Dewar <dewar@adacore.com>
18180 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18181 generate the same errors compiling under -gnatc.
18182 (Try_Object_Operation): If no candidate interpretation succeeds, but
18183 there is at least one primitive operation with the right name, report
18184 error in call rather than on a malformed selected component.
18185 (Analyze_Selected_Component): If the prefix is an incomplete type from
18186 a limited view, and the full view is available, use the full view to
18187 determine whether this is a prefixed call to a primitive operation.
18188 (Operator_Check): Verify that a candidate interpretation is a binary
18189 operation before checking the type of its second formal.
18190 (Analyze_Call): Add additional warnings for function call contexts not
18192 (Analyze_Allocator): Move the check for "initialization not allowed for
18193 limited types" after analyzing the expression. This is necessary,
18194 because OK_For_Limited_Init looks at the structure of the expression.
18195 Before analysis, we don't necessarily know what sort of expression it
18196 is. For example, we don't know whether F(X) is a function call or an
18197 indexed component; the former is legal in Ada 2005; the latter is not.
18198 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18199 were missing. We also didn't handle qualified expressions. Now also
18200 allow function calls. Use new common routine OK_For_Limited_Init.
18201 (Analyze_Type_Conversion): Do not perform some legality checks in an
18202 instance, because the error message will be redundant or spurious.
18203 (Analyze_Overloaded_Selected_Component): Do not do style check when
18204 setting an entity, since we do not know it is the right entity yet.
18205 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18206 (Analyze_Overloaded_Selected_Component): Same change
18207 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18208 since regular incomplete subtypes are transformed into corresponding
18209 subtypes of their full views.
18210 (Complete_Object_Operation): Treat name of transformed subprogram call
18211 as coming from source, for browsing purposes.
18212 (Try_Primitive_Operation): If formal is an access parameter, compare
18213 with base type of object to determine whether it is a primitive
18215 (Operator_Check): If no interpretation of the operator matches, check
18216 whether a use clause on any candidate might make the operation legal.
18217 (Try_Class_Wide_Operation): Check whether the first parameter is an
18218 access type whose designated type is class-wide.
18220 2006-10-31 Robert Dewar <dewar@adacore.com>
18221 Ed Schonberg <schonberg@adacore.com>
18222 Gary Dismukes <dismukes@adacore.com>
18224 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
18225 warn on infinite loops.
18226 Add \\ to some continuation messages
18227 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18228 (Process_Bounds): If the bounds are integer literals that result from
18229 constant-folding, and they carry a user-defined type, preserve that type
18230 rather than treating this as an integer range.
18231 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18232 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18233 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18234 left hand side of assignment.
18235 (Analyze_Assignment): Add suport to manage assigments to the attribute
18236 priority of a protected object.
18237 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18238 not just identifiers.
18239 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18240 or AND THEN for possible tracking.
18241 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18242 case of while loops so we can track values in the loop body.
18244 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18245 Hristian Kirtchev <kirtchev@adacore.com>
18246 Bob Duff <duff@adacore.com>
18248 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18249 procedure cannot be a protected operation (it is a basic_declaration,
18250 not a subprogram_declaration).
18251 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18252 Subp. Add logic for entry processing.
18253 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18254 Determine whether an entry or subprogram of a protected or task type
18255 override an inherited primitive of an implemented interface.
18256 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18257 Update the actual used in calls to Check_Overriding_Indicator.
18258 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18259 generate the proper reference to the parent unit, for cross-reference.
18260 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18262 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18263 (Add_Extra_Formal): Revise procedure to allow passing in associated
18264 entity, scope, and name suffix, and handle setting of the new
18265 Extra_Formals field.
18266 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18267 pass new parameters. Add support for adding the new extra access formal
18268 for functions whose calls are treated as build-in-place.
18269 (Analyze_A_Return_Statement): Correct casing in error message.
18270 Move Pop_Scope to after Analyze_Function_Return, because an extended
18271 return statement really is a full-fledged scope. Otherwise, visibility
18272 doesn't work right. Correct use of "\" for continuation messages.
18273 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18274 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18275 the node doesn't get properly marked as analyzed.
18276 (Analyze_Subprogram_Body): If subprogram is a function that returns
18277 an anonymous access type that denotes a task, build a Master Entity
18279 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18280 proper usage of null exclusion in a result definition.
18281 (Process_Formals): Code cleanup and new error message.
18282 (Process_Formals): Detect incorrect application of null exclusion to
18284 (Conforming_Types): Handle conformance between [sub]types and itypes
18285 generated for entities that have null exclusions applied to them.
18286 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18287 base type is an access subtype. This case arrises with null exclusions.
18288 (New_Overloaded_Entity): Do not remove the overriden entity from the
18289 homonym chain if it corresponds with an abstract interface primitive.
18290 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18291 call to the synthesized predicate Is_Incomplete_Type.
18292 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18294 (Analyze_Subprogram_Declaration): Check that abstract interface
18295 primitives are abstract or null.
18296 (Analyze_Subprogram_Specification): Remove previous check for abstract
18297 interfaces because it was not complete.
18298 (Has_Interface_Formals): Removed.
18300 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18301 Javier Miranda <miranda@adacore.com>
18303 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18304 of Analyze_Package_Body, to create Itype references for anonymous
18305 access types created in the package declaration, whose designated types
18306 may have only a limited view.
18307 (Analyze_Package_Specification): For the private part of a nested
18308 package, install private_with_clauses of enclosing compilation unit if
18309 we are in its visible part.
18310 (Declare_Inherited_Private_Subprograms): Complete barrier
18311 to ensure that the primitive operation has an alias to some parent
18312 primitive. This is now required because, after the changes done for the
18313 implementation of abstract interfaces, the contents of the list of
18314 primitives has entities whose alias attribute references entities of
18315 such list of primitives.
18316 (Analyze_Package_Specification): Simplify code that handles parent units
18317 of instances and formal packages.
18318 (Uninstall_Declarations): Check the convention consistency among
18319 primitive overriding operations of a tagged record type.

18326 * sem_ch8.adb: Minor error msg rewording
18327 (Undefined): When checking for misspellings, invert arguments (to get
18328 expected and found set right)
18329 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18330 (Analyze_Generic_Renaming): Same fix
18331 (Use_One_Package): Do not take into account the internal entities of
18332 abstract interfaces during the analysis of entities that are marked
18333 as potentially use-visible.
18334 (Find_Type): Handle the case of an attribute reference for
18335 implementation defined attribute Stub_Type (simply let the analysis of
18336 the attribute reference rewrite it).

19559 other basic tools. The full version that includes the Ada 2005 stuff

19822 Eric Botcazou <ebotcazou@adacore.com>
19824 * err_vars.ads: Suppress range checks for a couple of assignments

19835 implied by '?' in error messages.
19837 * gnat1drv.adb: (Bad_Body): Remove '!' in warning message.
19838 (Gnat1drv): Use a goto to end of main subprogram instead of

19857 Thomas Quinot <quinot@adacore.com>
19859 * checks.adb (Build_Discriminant_Checks): If the expression being
19860 checks is an aggregate retrieve the values of its discriminants to
19861 generate the check, rather than creating a temporary and a reference

19864 (Install_Null_Excluding_Check): Ditto
19865 (Selected_Length_Checks): Build actual subtype for the original Ck_Node,

19883 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
19884 Remove 0-9 as debug flag character possibilities
19885 -d is now controlling the primary stack size when its value is a
19886 positive. Also add checks against invalid values, and support for kb,
19887 mb. Ditto for -D switch.
19889 2006-02-13 Robert Dewar <dewar@adacore.com>
19890 Serguei Rybin <rybin@adacore.com>
19892 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
19893 save/restore routines.
19894 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19895 were not always properly handled previously.
19896 Since we are changing the tree format anyway, also get rid of the
19897 junk obsolete Immediate_Errors flag.
19898 (Tree_Read): Change the way of reading Tree_Version_String - now we
19899 read the version string from the tree even if its length is not the
19900 same as the length of the version string computed from Gnatvsn.
19901 (Search_Directory_Present): New Boolean flag for the compiler.
19902 Define Tree_Version_String as a dynamic string.

19917 Ed Schonberg <schonberg@adacore.com>
19919 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
19920 against errors in the source program: a private types for which the
19921 corresponding full type declaration is missing and pragma CPP_Virtual
19923 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
19924 (Is_Known_Null): New flag
19925 (Has_Pragma_Pure): New flag
19926 (No_Return): Present in all entities, set only for procedures
19927 (Is_Limited_Type): A type whose ancestor is an interface is limited if
19928 explicitly declared limited.
19929 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
19930 entities. Only used for component marked Is_Tag. If present it stores

19932 whose ancestor has discriminants.
19934 * exp_ch2.adb: Update status of new Is_Known_Null flag
19936 * sem_ch7.adb: Maintain status of new Is_Known_Null flag

19950 (__gnat_handle_vms_condition): Adjust context before raise.
19951 (__gnat_install_handler): Restore the global vector setup for GCC
19952 versions before 3.4, as the frame based circtuitry is not available

19955 (__gl_default_stack_size): new variable.
19957 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19959 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
19960 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
19961 does not exist in the Ada RM.
19962 (Compatible_Int_Bounds): Determine whether two integer range bounds
19963 are of equal length and have the same start and end values.
19964 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
19965 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
19966 aggregate when it is part of an object declaration.
19967 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
19968 constrains discriminants of its parent, add explicitly the discriminant
19969 constraints of the ancestor by retrieving them from the
19970 stored_constraint of the parent.
19972 2006-02-13 Robert Dewar <dewar@adacore.com>
19974 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
19975 attribute Mechanism_Code is applied to renamed subprogram, modify
19976 prefix to point to base subprogram.
19977 Max/Min attributes now violate Restriction No_Implicit_Conditionals
19979 * sinfo.ads: Document that Mechanism_Code cannot be applied to
19980 renamed subprograms so that the front-end must replace the prefix
19983 2006-02-13 Javier Miranda <miranda@adacore.com>
19984 Gary Dismukes <dismukes@adacore.com>
19986 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
19987 availability of RE_Interface_Tag.
19988 (Build_Initialization_Call): Fix wrong access to the discriminant value.
19989 (Freeze_Record_Type): Do not generate the tables associated with
19990 timed and conditional dispatching calls through synchronized
19991 interfaces if compiling under No_Dispatching_Calls restriction.
19992 When compiling for Ada 2005, for a nonabstract
19993 type with a null extension, call Make_Controlling_Function_Wrappers
19994 and insert the wrapper function declarations and bodies (the latter
19995 being appended as freeze actions).
19996 (Predefined_Primitive_Bodies): Do not generate the bodies of the
19997 predefined primitives associated with timed and conditional
19998 dispatching calls through synchronized interfaces if we are
19999 compiling under No_Dispatching_Calls.
20000 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20001 service is available before generating a call.
20002 (Make_Controlling_Function_Wrappers): New procedure.
20003 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20004 access-to-limited-interfaces because they can be used to reference
20005 tasks that implement such limited interface.
20006 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20007 procedure spec and body of the Offset_To_Top function that is generated
20008 when the parent of a type with discriminants has secondary dispatch
20010 (Init_Secondary_Tags): Handle the case in which the parent of the type
20011 containing secondary dispatch tables has discriminants to generate the
20012 correct arguments to call Set_Offset_To_Top.
20013 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20015 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20016 Add Wide_[Wide_]Expanded_Name.
20017 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20018 the same functionality of Get_Prim_Op_Address but applied to predefined
20019 primitive operations because the pointers to the predefined primitives
20020 are now saved in a separate table.
20021 (Parent_Size): Modified to get access to the separate table of primitive
20022 operations or the parent type.
20023 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20024 functionality of Set_Prim_Op_Address but applied to predefined primitive
20026 (Set_Signature): New subprogram used to store the signature of a DT.
20027 (Displace): If the Offset_To_Top value is not static then call the
20028 function generated by the expander to get such value; otherwise use
20029 the value stored in the table of interfaces.
20030 (Offset_To_Top): The type of the actual has been changed to Address to
20031 give the correct support to tagged types with discriminants. In this
20032 case this value is stored just immediately after the tag field.
20033 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20034 offset_to_top value is static and hence pass this value to the run-time
20035 to store it in the table of interfaces, or else if this value is dynamic
20036 and then pass to the run-time the address of a function that is
20037 generated by the expander to provide this value for each object of the
20040 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20041 (Default_Prim_Op_Count): New entity
20042 (Get_Predefined_Prim_Op_Address): New entity

20047 Ed Schonberg <schonberg@adacore.com>
20049 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20050 Make_Adjust_Call done for a newly-allocated object.
20052 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20053 in a subprogram are wrapped in a cleanup block, indicate that the
20054 subprogram contains an inner block with an exception handler.
20055 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20056 Adjust call is for a newly-allocated object. In that case we must not
20057 assume that the finalization list chain pointers are correct (since they
20058 come from a bit-for-bit copy of the original object's pointers) so if
20059 the attach level would otherwise be zero (no change), we set it to 4
20060 instead to cause the pointers to be reset to null.
20062 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20063 reset chain pointers to null.
20065 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20067 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20068 string, and the context requires a loop for the assignment (e.g.
20069 because the left-hand side is packed), generate a unique name for the
20070 temporary that holds the string, to prevent spurious name clashes.
20072 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20073 Javier Miranda <miranda@adacore.com>
20074 Robert Dewar <dewar@adacore.com>
20075 Gary Dismukes <dismukes@adacore.com>
20077 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20078 return unconstrained arrays.
20080 (Expand_Call): An indirect call through an access parameter of a
20081 protected operation is not a protected call.
20082 Add circuit to raise CE in Ada 2005 mode following call
20083 to Raise_Exception.
20084 (Register_DT_Entry): Do nothing if
20085 the run-time does not give support to abstract interfaces.
20086 (Freeze_Subprogram): In case of dispatching operations, do not generate
20087 code to register the operation in the dispatch table if the source
20088 is compiled with No_Dispatching_Calls.
20089 (Register_Predefined_DT_Entry): Generate code that calls the new
20090 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20091 Set_Prim_Op_Address.
20093 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20094 on array assignments if the right-hand side is a function call that has
20095 been inlined. Check is performed on the assignment in the block.
20096 (Process_Bounds): If bounds and range are overloaded, apply preference
20097 rule for root operations to disambiguate, and diagnose true ambiguity.
20098 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20099 a tag-indeterminate right-hand side even when Expander_Active is True.
20100 Needed to ensure that dispatching calls to T'Input are allowed and
20101 get the tag of the target class-wide object.
20103 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20104 an inherited primitive operation that already overrides several
20105 abstract interface primitives. For transitivity, the new entity must
20106 also override all the abstract interface primitives covered by the
20107 inherited overriden primitive.
20108 Emit warning if new entity differs from homograph in same scope only in
20109 that one has an access parameter and the other one has a parameter of
20110 a general access type with the same designated type, at the same
20111 position in the signature.
20112 (Make_Inequality_Operator): Use source locations of parameters and
20113 subtype marks from corresponding equality operator when creating the
20114 tree structure for the implicit declaration of "/=". This does not
20115 change anything in behaviour except that the decoration of the
20116 components of the subtree created for "/=" allows ASIS to get the
20117 string images of the corresponding identifiers.
20118 (Analyze_Return_Statement): Remove '!' in warning message.
20119 (Check_Statement_Sequence): Likewise.
20120 (Analyze_Subprogram_Body): For an access parameter whose designated type
20121 is an incomplete type imported through a limited_with clause, use the
20122 type of the corresponding formal in the body.
20123 (Check_Returns): Implicit return in No_Return procedure now raises
20124 Program_Error with a compile time warning, instead of beging illegal.
20125 (Has_Single_Return): Function returning unconstrained type cannot be
20126 inlined if expression in unique return statement is not an identifier.
20127 (Build_Body_To_Inline): It is possible to inline a function call that
20128 returns an unconstrained type if all return statements in the function
20129 return the same local variable. Subsidiary procedure Has_Single_Return
20130 verifies that the body conforms to this restriction.
20132 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20133 same type, and one of them is of an anonymous access type, convert
20134 the other operand to it, so that this is a valid binary operation for
20136 (Resolve_Type_Conversion): Handle subtypes of protected types and
20137 task types when accessing to the corresponding record type.
20138 (Resolve_Allocator): Add '\' in 2-line warning message.
20139 Remove '!' in warning message.
20140 (Resolve_Call): Add '\' in 2-line warning message.
20141 (Valid_Conversion): Likewise.
20142 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20143 resulting type may be an access type with an implicit dereference.
20144 Obtain the proper component from the designated type.
20145 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20146 given by an expanded name with prefix Standard, when the operands are
20147 of an anonymous access type.
20148 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20149 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20150 prefix of the expression is not of an incomplete type. Allows full
20151 diagnoses of all semantic errors.
20152 (Resolve_Actuals): If the actual is an allocator whose directly
20153 designated type is a class-wide interface we build an anonymous
20154 access type to use it as the type of the allocator. Later, when
20155 the subprogram call is expanded, if the interface has a secondary
20156 dispatch table the expander will add a type conversion to force
20157 the displacement of the pointer.
20158 (Resolve_Call): If a function that returns an unconstrained type is
20159 marked Inlined_Always and inlined, the call will be inlined and does
20160 not require the creation of a transient scope.
20161 (Check_Direct_Boolean_Op): Removed
20162 (Resolve_Comparison_Op): Remove call to above
20163 (Resolve_Equality_Op): Remove call to above
20164 (Resolve_Logical_Op): Inline above, since this is only call.
20165 (Valid_Conversion): Handle properly conversions between arrays of
20166 convertible anonymous access types.
20169 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20170 the literal in an unchecked conversion, because GCC 4.x needs a static
20171 value for a string bound.
20173 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20174 Hristian Kirtchev <kirtchev@adacore.com>
20176 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20177 components of the corresponding record, take into account component
20178 definitions that are access definitions.
20179 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20180 procedure is not considered a dispatching call and will be expanded
20183 2006-02-13 Javier Miranda <miranda@adacore.com>
20185 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20186 controlling argument of the dispatching call is an abstract interface
20187 class-wide type then we use it directly.
20188 Check No_Dispatching_Calls restriction.
20189 (Default_Prim_Op_Position): Remove the code that looks for the last
20190 entity in the list of aliased subprograms. This code was wrong in
20192 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20193 when the source is compiled with the No_Dispatching_Calls restriction.
20194 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20195 if we are compiling with restriction No_Dispatching_Calls.
20196 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20197 subprograms if we are compiling under No_Dispatching_Calls restriction.
20198 (Make_DT): Generate a dispatch table with a single dummy entry if
20199 we are compiling with the No_Dispatching_Calls restriction. In
20200 addition, in this case we don't generate code that calls to the
20201 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20202 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20203 of this subprogram if compiling with the No_Dispatching_Calls
20205 (Expand_Type_Conversion): Instead of using the actual parameter,
20206 the argument passed as parameter to the conversion function was
20207 erroneously referenced by the expander.
20208 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20209 Set_Predefined_Primitive_Op_Address and Set_Signature.
20210 (Expand_Dispatching_Call): Generate call to
20211 Get_Predefined_Prim_Op_Address for predefined primitives.
20212 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20213 predefined primitives.
20214 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20215 primitives we reserve one dummy entry to ensure that the tag does not
20216 point to some memory that is associated with some other object. In
20217 addition, remove all the old code that generated the assignments
20218 associated with the signature of the dispatch table and replace them
20219 by a call to the new subprogram Set_Signature.
20220 (Set_All_DT_Position): Change the algorithm because now we have a
20221 separate dispatch table associated with predefined primitive operations.
20222 (Expand_Interface_Conversion): In case of non-static offset_to_top
20223 add explicit dereference to get access to the object after the call
20224 to displace the pointer to the object.
20225 (Expand_Interface_Thunk): Modify the generation of the actual used
20226 in the calls to the run-time function Offset_To_Top to fulfil its
20228 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.

20232 * exp_dist.adb (Copy_Specification): For access parameters, copy
20233 Null_Exclusion flag, which will have been set for stream subprograms
20236 2006-02-13 Pascal Obry <obry@adacore.com>
20238 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20239 previous implementation was using the C runtime spawnve routine but
20240 the corresponding wait was using directly the Win32 API. This was
20241 causing some times a lock when waiting for an event using
20242 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20243 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20244 API fixes this problem.
20246 2006-02-13 Robert Dewar <dewar@adacore.com>

20267 searching for the predefined equality operator, verify that operands
20268 have the same type.
20269 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20270 for the last entity in the list of aliased subprograms. This code
20271 was wrong in case of renamings.
20272 (Set_Renamed_Subprogram): New procedure
20273 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20274 Exp_Type constant computed when entering this subprogram.

20279 side effect, unlike other attributes that are functions. (from code
20281 (Remove_Side_Effects): Expressions that involve packed arrays or records
20282 are copied at the point of reference, and therefore must be marked as
20283 renamings of objects.

20285 not a dispatching operation.
20288 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20289 elementary types in all cases.

20294 task types when accessing to the corresponding record type.
20295 Remove '!' in warning message.
20297 2006-02-13 Olivier Hainque <hainque@adacore.com>
20299 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20300 to avoid useless and space inefficient overalignments on targets where
20301 Max_Alignment is larger than 16.
20303 2006-02-13 Pascal Obry <obry@adacore.com>
20305 * g-catiio.adb (Sec_Number): New type used to compute the number of
20306 seconds since 1-1-1970.
20307 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20308 negative numbers (years, months...) it is better to have a Natural here.
20310 (Image) [Number]: Change parameter from Long_Integer to Number.
20311 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20312 overflow for dates past year 2038.
20314 2006-02-13 Matthew Heaney <heaney@adacore.com>
20316 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20319 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20321 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20323 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20324 finalization can occur normally.
20326 2006-02-13 Vincent Celier <celier@adacore.com>
20328 * gnatcmd.adb (Rules_Switches): New table
20329 (Add_To_Rules_Switches): New procedure
20330 (GNATCmd): For command CHECK, put all options following "-rules" in the
20331 Rules_Switches table. Append these -rules switches after the -cargs
20334 2006-02-13 Robert Dewar <dewar@adacore.com>
20336 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20337 These two cases were generating incorrect output, and if this unit
20338 was built with checks on, generated a discriminant mismatch constraint
20341 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20342 Robert Dewar <dewar@adacore.com>
20344 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20345 view is an array type, indicate the component type as well, for
20346 navigation purposes.
20347 (Generate_Reference): Don't consider array ref on LHS to be a case
20348 of violating pragma Unreferenced.
20349 Do not give Ada 2005 warning except on real reference.
20351 2006-02-13 Vincent Celier <celier@adacore.com>
20353 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20354 main source, add switch -mdebug-main=_ada_ so that the executable can
20355 be debugged by the standard VMS debugger.
20356 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20357 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20358 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20359 of the last source, as the binding and linking phases are never
20361 Set all executable obsolete when rebuilding a library.
20363 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20366 2006-02-13 Javier Miranda <miranda@adacore.com>
20369 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20370 code to improve the error message reported when the program has
20371 declarations of abstract interface types and it is not compiled with
20372 the -gnat05 switch.
20373 (P_Access_Definition): Reorganize the code to improve the error
20374 message reported when the new Ada 2005 syntax for anonymous

20398 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20399 unknown, use the location of the project to report the error.
20400 (When_No_Sources): New global variable
20401 (Report_No_Ada_Sources): New procedure
20402 (Check): New parameter When_No_Sources. Set value of global variable
20404 (Find_Sources): Call Report_No_Ada_Sources when appropriate
20405 (Get_Sources_From_File): Ditto
20406 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20409 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20410 Call Prj.Proc.Process with parameter When_No_Sources.
20412 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20413 Call Recursive_Check with parameter When_No_Sources.
20414 (Recursive_Check): New parameter When_No_Sources. Call itself and
20415 Prj.Nmsc.Check with parameter When_No_Sources.
20416 (Process): New parameter When_No_Sources. Call Check with parameter
20418 (Copy_Package_Declarations): New procedure to copy renamed parameters
20419 and setting the location of the declared attributes to the location
20420 of the renamed package.

20428 When removing nodes (attributes Source_Dirs, Source_Files,
20429 Source_List_File and package Naming), save the comments and attach the
20430 saved comments to the newly created nodes.
20431 Do not add a with clause for the naming package if one already exists.

20443 (Check_Dispatching_Operation): Do not generate code to register the
20444 operation in the dispatch table if the source is compiled with
20445 restriction No_Dispatching_Calls.

20447 No_Return procedure with procedure that is not No_Return
20448 (Check_Dispatching_Call): Suppress the check for an abstract operation
20449 when the original node of an actual is a tag-indeterminate attribute
20450 call, since the attribute, which must be 'Input, can never be abstract.
20451 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20452 call to the Input attribute (even when rewritten).
20453 (Propagate_Tag): Augment comment to indicate the possibility of a call
20454 to an Input attribute.
20456 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20457 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.

20466 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20468 2006-02-13 Javier Miranda <miranda@adacore.com>
20470 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20471 handles default-initialized components to keep separate the management
20472 of this feature but also avoid the unrequired resolution and
20473 expansion of components that do not have partially initialized
20475 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20476 (Check_Bounds): Likewise.
20477 (Check_Length): Likewise.
20479 2006-02-13 Javier Miranda <miranda@adacore.com>
20480 Ed Schonberg <schonberg@adacore.com>
20482 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20483 abstract interface type call analyze_and_resolve to expand the type
20484 conversion into the corresponding displacement of the
20485 reference to the base of the object.
20486 (Eval_Attribute, case Width): For systems where IEEE extended precision
20487 is supported, the maximum exponent occupies 4 decimal digits.
20488 (Accessibility_Message): Add '\' in 2-line warning message.
20489 (Resolve_Attribute): Likewise.
20490 (case Attribute_Access): Significantly revise checks
20491 for illegal access-to-subprogram Access attributes to properly enforce
20492 the rules of 3.10.2(32/2).
20493 Diagnose use of current instance with an illegal attribute.
20495 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20497 (Enclosing_Generic_Unit): New function to return a node's innermost
20498 enclosing generic declaration node.
20499 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20500 (Type_Access_Level): The accessibility level of anonymous acccess types
20501 associated with discriminants is that of the current instance of the
20502 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20503 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20504 (Kill_Current_Values_For_Entity): New function
20505 (Enter_Name): Change formal type to Entity_Id
20507 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20508 Ed Schonberg <schonberg@adacore.com>

20511 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20512 Analyze_Compilation_Unit.
20513 Detect and warn on redundant with clauses detected in a package spec
20514 and/or body when -gnatwr is used.
20515 (Analyze_Context): Analyze config pragmas before other items
20516 (Install_Context_Items): Don't analyze config pragmas here
20517 (Install_Limited_Withed_Unit): Set limited entity of package in
20518 with_clause so that cross-reference information or warning messages on
20519 unused packages can be properly generated
20520 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20521 has Error_Posted set. Prevent infinite loops in illegal programs.
20522 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20523 to the point of the error test requiring the current unit to be private.
20524 This ensures that private with clauses are not exempted from the basic
20525 checking for being a descendant of the same library unit parent as a
20526 withed private descendant unit.
20527 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20528 handle private with clauses properly, as well as to account for cases
20529 where the withed unit is a public descendant of a private ancestor
20530 (in which case the current unit must be a descendant of the private
20531 ancestor's parent). The spec comments were updated accordingly. Also,
20532 the old error message in this subprogram was replaced with error
20533 messages that mirror the errors tested and reported by
20534 Check_Private_Child_Unit.
20535 Parameter and variable names improved for readability.
20536 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20537 private as the precondition for calling
20538 Check_Private_Limited_Withed_Unit since that subprogram has been
20539 revised to test public units as well as private units.

20544 Javier Miranda <miranda@adacore.com>
20546 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20547 that Scope_Stack.First = 1.
20548 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20549 were not always properly handled previously.

20551 with multiple levels of parametrization by formal packages.
20552 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20553 to the corresponding derived type declaration for proper semantics.
20555 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20556 (Check_Component): Enforce restriction on components of
20557 unchecked_unions: a component in a variant cannot contain tasks or
20559 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20561 Add pragma Ada_2005 (synonym for Ada_05)
20562 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20563 were not always properly handled previously.
20564 Document that pragma Propagate_Exceptions has no effect
20565 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20566 (Set_Convention_From_Pragma): Check that if a convention is
20567 specified for a dispatching operation, then it must be
20568 consistent with the existing convention for the operation.
20569 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20570 longer required to specify an vtable-ptr component in the record. For
20571 compatibility reasons we leave the support for the previous definition.
20572 (Analyze_Pragma, case No_Return): Allow multiple arguments
20574 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20575 non-overrideen inherited operation with a controlling result as
20576 illegal only its implicit declaration comes from the derived type
20577 declaration of its result's type.
20578 (Check_Possible_Deferred_Completion): Relocate the object definition
20579 node of the subtype indication of a deferred constant completion rather
20580 than directly analyzing it. The analysis of the generated subtype will
20581 correctly decorate the GNAT tree.
20582 (Record_Type_Declaration): Check whether this is a declaration for a
20583 limited derived record before analyzing components.
20584 (Analyze_Component_Declaration): Diagnose record types not explicitly
20585 declared limited when a component has a limited type.
20586 (Build_Derived_Record_Type): Code reorganization to check if some of
20587 the inherited subprograms of a tagged type cover interface primitives.
20588 This check was missing in case of a full-type associated with a private
20590 (Constant_Redeclaration): Check that the subtypes of the partial and the
20591 full view of a constrained deferred constant statically match.
20592 (Mentions_T): A reference to the current type in an anonymous access
20593 component declaration must be an entity name.
20594 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20595 class_wide type to refer to full type, not to the incomplete one.
20596 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20597 available. Required to give support to the certified run-time.
20598 (Analyze_Component_Declaration): In case of anonymous access components
20599 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20600 (Process_Discriminants): For an access discriminant, use the
20601 discriminant specification as the associated_node_for_itype, to
20602 simplify accessibility checks.
20604 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20605 Javier Miranda <miranda@adacore.com>
20607 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20608 abstract interpretations on an operator, remove interpretations that
20609 yield Address or a type derived from it, if one of the operands is an
20611 (Try_Object_Operation.Try_Primitive_Operation,
20612 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20613 location when creating the new reference to a primitive or class-wide
20614 operation as a part of rewriting a subprogram call.
20615 (Try_Primitive_Operations): If context requires a function, collect all
20616 interpretations after the first match, because there may be primitive
20617 operations of the same type with the same profile and different return
20618 types. From code reading.
20619 (Try_Primitive_Operation): Use the node kind to choose the proper
20620 operation when a function and a procedure have the same parameter
20622 (Complete_Object_Operation): If formal is an access parameter and prefix
20623 is an object, rewrite as an Access reference, to match signature of
20624 primitive operation.
20625 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20626 by an expanded name with prefix Standard, when the operands are of an
20627 anonymous access type.
20628 (Remove_Abstract_Operations): If the operation is abstract because it is
20629 inherited by a user-defined type derived from Address, remove it as
20630 well from the set of candidate interpretations of an overloaded node.
20631 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20634 2006-02-13 Bob Duff <duff@adacore.com>
20636 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20637 redundant use clauses.
20638 In particular, if the scope of two use clauses overlaps, but one is not
20639 entirely included in the other, we should not warn. This can happen
20640 with nested packages.
20641 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20642 reported errors. The bug was reported when the compiler was built
20643 with assertions enabled.
20644 (Find_Type): If the node is a 'Class reference and the prefix is a
20645 synchronized type without a corresponding record, return the type
20648 2006-02-13 Javier Miranda <miranda@adacore.com>
20650 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20651 if this is the full-declaration associated with a private declaration
20652 that implement interfaces, then the private type declaration must be
20654 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20655 as aliased. The use of the 'access attribute is not available for such
20656 object (for this purpose the object should be explicitly marked as
20657 aliased, but being an anonymous type this is not possible).
20659 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20660 Robert Dewar <dewar@adacore.com>
20662 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20663 compilation unit is an elaboration scope.
20664 (Add_Task_Proc): Add '\' in 2-line warning message.
20665 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20667 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20668 Javier Miranda <miranda@adacore.com>
20670 * sem_type.adb (Write_Overloads): Improve display of candidate
20672 (Add_One_Interp): Do not add to the list of interpretations aliased
20673 entities corresponding with an abstract interface type that is an
20674 immediate ancestor of a tagged type; otherwise we have a dummy
20675 conflict between this entity and the aliased entity.
20676 (Disambiguate): The predefined equality on universal_access is not
20677 usable if there is a user-defined equality with the proper signature,
20678 declared in the same declarative part as the designated type.
20679 (Find_Unique_Type): The universal_access equality operator defined under
20680 AI-230 does not cover pool specific access types.
20681 (Covers): If one of the types is a generic actual subtype, check whether
20682 it matches the partial view of the other type.
20684 2006-02-13 Thomas Quinot <quinot@adacore.com>
20686 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20687 line. This is necessary to allow In_Extended_Main_Unit to provide
20688 correct results for itypes while writing out expanded source.
20689 (Close_File): No need to update the source_index_table here since it's
20690 now done for each line.
20692 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20693 Robert Dewar <dewar@adacore.com>
20695 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20696 preserve the source unit where the itype is declared, and prevent a
20698 (Note_Implicit_Run_Time_Call): New procedure
20699 (Write_Itype): Handle missing cases (E_Class_Wide_Type and

20709 2006-02-13 Bob Duff <duff@adacore.com>
20711 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20712 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20713 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20714 raise Constraint_Error.
20716 * s-vallli.adb (Scan_Long_Long_Integer): Call
20717 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20718 do not scan leading blanks and sign twice.
20719 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20720 raise Constraint_Error.
20722 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20723 Scan_Long_Long_Unsigned): Split out most of the processing from
20724 Scan_Long_Long_Unsigned out into
20725 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20726 This prevents scanning leading blanks and sign twice.
20727 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20730 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20731 out most of the processing from Scan_Unsigned out into
20732 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20733 This prevents scanning leading blanks and sign twice.
20735 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20736 use with Modular'Value attribute.
20737 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

20933 Florian Villoing <villoing@adacore.com>
20935 * a-taster.ads, a-taster.adb: New files.
20937 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
20938 link to the version that does nothing. This way the task termination
20939 routine is not executed twice for the environment task when finishing
20940 because of an unhandled exception.
20942 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
20943 handler because of an unhandled exception.
20945 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
20946 System.Tasking.Utilities instead of that in System.Tasking.Stages.

20949 finalization of the global list instead of Adafinal.
20951 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
20952 non-tasking version of the soft link for task termination. We do
20953 nothing since if we are using the non-tasking version it
20954 means that the task termination functionality is not used.
20955 (Null_Finalize_Global_List): Add this null version for the procedure
20956 in charge of finalizing the global list for controlled objects.
20957 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
20958 instead for handling run-time termination in a more flexible way.
20959 (Adafinal_NT): This new procedure will take care of finalizing the
20960 global list for controlled objects if needed, but no tasking
20963 * s-tarest.adb (Task_Lock): Do not try to lock again the
20964 Global_Task_Lock if we already own it. Otherwise, we get blocked in
20965 some run-time operations.
20966 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
20967 until all nested locks have been released.
20968 (Task_Wrapper): Call the fall-back task termination handler. It
20969 applies to all tasks but the environment task.
20970 (Finalize_Global_Tasks): Add the call for the task termination
20971 procedure for the environment task.
20972 (Task_Wrapper): suppress warnings around declaration of
20973 Secondary_Stack_Address.
20975 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
20976 moved to the Common_ATCB record.
20977 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
20978 Common_ATCB record.
20979 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
20980 Common_ATCB record.
20982 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
20983 Fall_Back_Handler, and Specific_Handler.
20985 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
20986 defined in Ada.Task_Termination, to avoid circular dependencies.
20987 (Termination_Handler): Redefine this type here, alredy defined in
20988 Ada.Task_Termination, for avoiding circular dependencies.
20989 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
20990 for storing task termination handlers. In addition,
20991 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
20992 Common_ATCB because it is used by both the regular and the restricted
20994 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
20995 Common_ATCB because it is used by both the regular and the restricted
20997 (Common_ATCB): Added a dynamic task analyzer field.
20999 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21000 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21001 (Task_Wrapper): Call the task termination handler. It applies to all
21002 tasks but the environment task.
21003 (Finalize_Global_Tasks): Call the task termination procedure for the
21004 environment task. The call to Finalize_Global_List is now performed
21005 using the soft links mechanism.
21006 (Task_Wrapper): added dynamic stack analysis.
21008 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21009 potentially blocking operations has been moved from
21010 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21011 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21012 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21013 this run-time check.
21015 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21016 of task termination procedure.
21017 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21018 link for the task termination procedure.

21034 (Standart_Output): new subprogram
21035 (Set_Output): new subprogram
21036 (Put): now uses the value of Current_Out to know if the output has to be
21037 send to stderr or stdout.
21039 * s-stausa.ads: Complete implementation.
21041 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
21043 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
21044 list of Ada 05 files.
21045 (GNAT Library Units): Add AltiVec files.

21059 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21060 to the specification because the frontend generates code that uses this
21062 (Set_Interface_Table): Add missing assertion.
21063 Update documentation describing the run-time structure.
21064 (Displace): New subprogram that displaces the pointer to the object
21065 to reference one of its secondary dispatch tables.
21066 (IW_Membership): Modified to use the new table of interfaces.
21067 (Inherit_TSD): Modified to use the new table of interfaces.
21068 (Register_Interface_Tag): Use the additional formal to fill the
21069 contents of the new table of interfaces.
21070 (Set_Interface_Table): New subprogram that stores in the TSD the
21071 pointer to the table of interfaces.
21072 (Set_Offset_To_Top): Use the additional formal to save copy of
21073 the offset value in the table of interfaces.

21085 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21086 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21087 record component containing the tag of the secondary dispatch table we
21088 have to use the Offset_To_Top run-time function to get this information;
21089 otherwise if the pointer to the base of the object has been displace
21090 we get a wrong value if we use the 'position attribute.
21092 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21093 all the calls to Expand_Interface_Thunk.
21094 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
21095 interfaces; hence the call to Set_Interface_Table was clearly wrong.
21096 (Collect_All_Interfaces): Modify the internal subprogram Collect to
21097 ensure that the interfaces implemented by the ancestors are placed
21098 at the header of the generated list.
21099 (Expand_Interface_Conversion): Handle the case in which the displacement
21100 associated with the interface conversion is not statically known. In
21101 this case we generate a call to the new run-time subprogram Displace.
21102 (Make_DT): Generate and fill the new table of interfaces.
21103 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21104 Get_Tagged_Kind and Set_Tagged_Kind.
21105 (Tagged_Kind): New function that determines the tagged kind of a type
21106 with respect to limitedness and concurrency and returns a reference to
21108 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
21109 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
21110 primary dispatch table for a type.
21111 (Make_DT, Make_Secondary_DT): Set the tagged kind in the primary and
21112 secondary dispatch table respectively of a tagged type.
21114 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
21115 (Expand_Interface_Conversion): New subprogram to indicate if the
21116 displacement of the type conversion is statically known.
21117 (DT_Access_Action): Add values Get_Tagged_Kind and Set_Tagged_Kind.
21119 * rtsfind.ads (RE_Offset_To_Top): New entity
21120 (RTU_Id): Add Ada_Task_Termination to the list so that it is made
21121 accessible to users.
21122 (Re_Displace): New entity

21124 (RE_Set_Interface_Data): New_Entity
21125 (RE_Id, RE_Unit_Table): Add entry for RE_Get_Tagged_Kind,
21126 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
21127 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
21128 RE_TK_Tagged, RE_TK_Task.
21130 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21131 Init_Secondary_Tags_Internal to allow its use with interface types and
21132 also to generate the code for the new additional actual required
21133 by Set_Offset_To_Top.
21134 (Build_Init_Statements): In case of components associated with abstract
21135 interface types there is no need to generate a call to its IP.
21136 (Freeze_Record_Type): Generate Select Specific Data tables only for
21138 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21139 the bodies and specifications of the predefined primitive operations
21140 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21141 for concurrent types.
21143 * exp_sel.ads, exp_sel.adb: New files.
21145 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21146 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21147 properly protected objects and attach handler in the case of the
21148 restricted profile.
21149 Move embeded package Select_Expansion_Utilities into a separate external
21151 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
21152 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
21153 (Build_K, Build_S_Assignment): New subprograms, part of the select
21154 expansion utilities.
21155 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Entry_Call,

21157 where the trigger is a dispatching procedure of a limited tagged type.
21159 2005-12-09 Olivier Hainque <hainque@adacore.com>
21161 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21162 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21163 about the use and expansion of SAVE_EXPRs in the various possible
21164 renaming handling cases.
21165 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21166 abusing DECL_FCONTEXT.
21168 2005-12-09 Matthew Heaney <heaney@adacore.com>

21286 type, return the entity associated with such abstract interface type.
21287 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
21288 base type to create anonymous subtype, because entity may be a locally
21289 declared subtype or generic actual.
21290 (Find_Interface): New subprogram that given a tagged type and one of its
21291 component associated with the secondary table of an abstract interface
21292 type, return the entity associated with such abstract interface type.
21294 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
21295 conversion cannot be handled at compile time. In this case we pass this
21296 information to the expander to generate the appropriate code.

21333 (Analyze_Component_Declaration): A limited component is
21334 legal within a protected type that implements an interface.
21335 (Collect_Interfaces): Do not add to the list the interfaces that
21336 are implemented by the ancestors.
21337 (Derived_Type_Declaration): If the parent of the full-view is an
21338 interface perform a transformation of the tree to ensure that it has
21339 the same parent than the partial-view. This simplifies the job of the
21340 expander in order to generate the correct object layout, and it is
21341 needed because the list of interfaces of the full-view can be given in
21343 (Process_Full_View): The parent of the full-view does not need to be
21344 a descendant of the parent of the partial view if both parents are
21346 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21347 "limited" the parent must be a limited type.

21361 (Process_Full_View): Improve the check for the "no hidden interface"
21362 rule as defined by AI-396.
21364 2005-12-09 Robert Dewar <dewar@adacore.com>
21366 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
21367 types, not on record subtypes.
21368 (Freeze_Entity): Code cleanup. Add barrier to the loop
21369 that generates the references for primitive operations. This allows to
21370 remove an unnecessary exception handler.

21421 available user-specified stream attributes on limited parameters to
21422 also test the type directly rather than only its underlying type (for
21423 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21424 attributes are visible at the point of the subprogram declaration.
21425 For Ada 2005, the error message is modified to indicate that the
21426 type's stream attributes must be visible (again, only for -gnat05).

21458 types use the corresponding record type. This was not needed before
21459 the implementation of Ada 2005 synchronized types because
21460 concurrent types were never tagged types in Ada 95.

21588 * socket.c: Add extern int h_errno for rtems since networking header
21589 files are not available at this point in a tool bootstrap. Newlib

21699 deal with different cases of static and dynamic elaboration checks (all
21700 checks does not count in the first case, but does in the second).

21706 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
21707 elementary types using the operator in standard. It is cleaner not to
21708 modify the programmers intent, especially in the case of floating-point.
21709 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
21710 it did not matter because we always rewrote a/=b to not(a=b).
21711 (Expand_Allocator_Expression): For an allocator expression whose nominal
21712 subtype is an unconstrained packed type, convert the expression to its
21713 actual constrained subtype.

21734 Allow optional = after -gnatm
21735 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
21736 longer sets Elaboration_Checks.
21737 Code to set warning mode moved to Sem_Warn
21738 so that it can be shared by pragma processing.
21740 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if

21865 we are not defining the type.
21866 <E_Record_Type>: Likewise.
21867 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
21868 to get advantage of the new maybe_stabilize_reference interface, to
21869 ensure that what we reference is indeed stabilized instead of relying
21870 on assumptions on what the stabilizer does.
21871 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
21872 type imported through a limited_with clause, use its non-limited view.
21873 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
21875 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
21876 of #if sections + explicit comparisons of convention identifiers.

21878 before early-returning for certain types when code generation is
21880 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

21882 that we are not defining.
21883 (elaborate_expression_1): Do not create constants when creating
21884 variables needed by the debug info: the dwarf2 writer considers that
21885 CONST_DECLs is used only to represent enumeration constants, and emits
21887 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
21888 object with an address clause into an indirect reference, drop the
21889 initializing expression.

21901 subtype to build an actual type with bounds template.
21902 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
21903 is provided by the front-end, use that subtype to compute the size of
21904 the deallocated object.

21906 check for a potential violation of a No_Elaboration_Code restriction.

21911 maybe_stabilize, for common uses without restriction on lvalues and
21912 without need to check for the success indication.
21913 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
21914 pass false instead of 0 as the FORCE argument which is a bool.
21915 (Identifier_to_gnu): Remove checks ensuring that an renamed object
21916 attached to a renaming pointer has been properly stabilized, as no such
21917 object is attached otherwise.
21918 (call_to_gnu): Invoke create_var_decl to create the temporary when the
21919 function uses the "target pointer" return mechanism.
21920 Reinstate conversion of the actual to the type of the formal
21921 parameter before any other specific treatment based on the passing

21931 * utils2.c (gnat_build_constructor): Only sort the fields for possible
21932 static output of record constructor if all the components are constant.
21933 (gnat_build_constructor): For a record type, sort the list of field
21934 initializers in increasing bit position order.
21935 Factor common code to build a storage type for an unconstrained object
21936 from a fat or thin pointer type and a constrained object type.
21937 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
21938 types variants, and process special cases of VIEW_CONVERT expressions
21939 as their NOP_EXPR counterpart to ensure we get to the
21940 CORRESPONDING_VARs associated with CONST_DECls.
21941 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
21942 on the right-hand side.

21949 extracting the object if converting to a type variant.
21950 (create_var_decl): When a variable has an initializer requiring code
21951 generation and we are at the top level, check for a potential violation
21952 of a No_Elaboration_Code restriction.
21953 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
21954 SIZE and SIZE_UNIT which we need for later back-annotations.

21957 is an unchecked union.

21959 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
21960 main variant, just replace the VIEW_CONVERT_EXPR.

22140 'Unrestricted_Access, if the designated type is an interface we
22141 add a type conversion to force the displacement of the pointer

22510 In addition some minor reorganization of the code has been done to
22511 leave it more clear.
22512 (Analyze_Type_Declaration): If type has previous incomplete tagged

22555 package associated with a generic instance or formal package, the
22556 private declarations of the parent must be installed (by calling new

22567 on the type may not have been generated.
22568 Handle properly a renaming_as_body generated for a stream operation
22569 whose default is abstract because the object type itself is abstract.
22570 (Find_Type): If the type is incomplete and appears as the prefix of a
22571 'Class reference, it is tagged, and its list of primitive operations
22572 must be initialized properly.
22573 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22574 private declaration of a parent unit, prior to compiling the private
22575 part of a child unit, find on the scope stack the proper parent entity
22576 on which to link the use clause.

22600 remove address operations.
22601 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22602 statement to inhibit warning.
22603 (Resolve_Unary_Op): Do not produce a warning when
22604 processing an expression of the form -(A mod B)
22605 Use Universal_Real instead of Long_Long_Float when we need a high

23647 position set is provided, we compute one in order to reduce the maximum
23648 length of the keys. This computation first selects a character
23649 position between 1 and the minimum length of the keys in order to
23650 avoid reducing one of the keys to an empty string.
23651 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23652 does not converge. The initialization procedure now comes with a

23746 including those that are inherited.
23748 2005-09-01 Robert Dewar <dewar@adacore.com>
23750 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
23752 * par-prag.adb: Implement new pragma Debug_Policy
23754 * sem_prag.adb Implement new pragma Debug_Policy
23755 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23756 Component_Size attribute specification. Give warning for ignored pragma
23759 * snames.h, snames.ads, snames.adb: Introduce entries in
23760 Preset_Names for Name_Disp_Asynchronous_Select,
23761 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23762 Name_Disp_Timed_Select.
23763 New pragma Debug_Policy
23765 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23767 Switch -gnata also sets Debug_Pragmas_Enabled
23769 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23770 handle an explicit -gnata when compiling predefined files.
23772 2005-09-01 Vincent Celier <celier@adacore.com>
23774 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23775 directories of projects that have no Ada sources.
23777 2005-09-01 Robert Dewar <dewar@adacore.com>
23779 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23780 (makes a difference for wide characters)
23782 * widechar.adb, widechar.ads:
23783 Add Wide_Char_Byte_Count feature to count chars vs bytes

23786 Ed Schonberg <schonberg@adacore.com>
23787 Robert Dewar <dewar@adacore.com>
23789 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23790 'Address attribute reference with an overloaded prefix, use the
23791 location of the prefix (not the location of the attribute reference) as
23792 the error location.
23793 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23794 a function renaming thereof, is a valid prefix for 'Size (where it is
23795 intepreted as a function call).
23796 (Statically_Denotes_Entity): New predicate to determine whether the
23797 prefix of an array attribute can be considered static.
23800 (Eval_Attr): Fix failure to evaluate Component_Size for
23801 unconstrained arrays (resulted in wrong value in packed case, since
23802 back end cannot handle this case)
23804 2005-09-01 Robert Dewar <dewar@adacore.com>
23806 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23807 error msgs for most common cases.
23808 Use new errout insertion char < (conditional warning)
23810 2005-09-01 Javier Miranda <miranda@adacore.com>
23811 Ed Schonberg <schonberg@adacore.com>
23813 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23814 become local to the whole package.
23815 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23816 the package was already analyzed the new algorithm "replaces" the
23817 real entities by the shadow ones. This is required to ensure that
23818 the order of these entities in the homonym chains does not change;
23819 otherwise we can have undefined references at linking time because
23820 in case of conflicts the external name of the entities will have
23821 a suffix that depends on the order of the entities in the chain.
23822 (Remove_Limited_With_Clause): Complementary code that completes the
23823 new algorithm and replaces the shadow entities by the real ones.
23824 (Install_Limited_Withed_Unit): When unchaining entities before the
23825 installation of the shadow entities, only regular entities of the
23826 public part must be taken into account. This is required to
23827 keep this routine in synch with the work done by Remove_Limited_
23829 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
23830 even if unit is analyzed, because the analysis of the unit is
23831 idempotent in any case, and the limited view of the unit may have to
23832 be installed for proper visibility.
23833 (Expand_Limited_With_Clause): Even if the unit in the implicit
23834 with_clause has been analyzed already, a limited view of the package
23835 must be built for the current context, if it does not exist yet.

23838 Javier Miranda <miranda@adacore.com>
23839 Gary Dismukes <dismukes@adacore.com>
23841 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
23842 defining entity for the instance body, make a new defining identifier
23843 rather than copying the entity of the spec, to prevent accidental
23844 sharing of the entity list.
23845 (Check_Private_View): When exchanging views of private types, build the
23846 list of exchanged views as a stack, to ensure that on exit the exchanges
23847 are undone in the proper order.
23848 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
23849 Restore the compilation environment in case of instantiation_error.
23850 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
23851 for an anonymous access result.
23852 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
23853 (Formal_Entity): Handle properly the case of a formal package that
23854 denotes a generic package renaming.
23856 2005-09-01 Thomas Quinot <quinot@adacore.com>
23858 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
23859 clause if the array aggregate is surrounded by parentheses.
23861 2005-09-01 Cyrille Comar <comar@adacore.com>
23862 Gary Dismukes <dismukes@adacore.com>
23863 Ed Schonberg <schonberg@adacore.com>
23864 Javier Miranda <miranda@adacore.com>
23866 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
23868 to check if a type is Constrained in cases related to code generation
23869 (rather than semantic checking) since otherwise we do not generate
23870 similar code for mutable private types depending if their
23871 discriminants are visible or not.
23872 (Check_Abstract_Overriding): Do not complain about failure to override
23873 the primitive operations used in dispatching selects since they will
23874 always be overriden at the freeze point of the type.
23875 (Access_Definition): Separate out handling for resetting the scope
23876 of an anonymous access function result type. Retrieve the scope
23877 of the associated function rather than using Current_Scope, which
23878 does not have a consistent value (depends on whether we're in the
23879 middle of analyzing formal parameters). Add ??? comment about
23880 finding a cleaner way to handle the special cases of scope setting.
23881 (Process_Incomplete_Dependents): A protected operation is never a
23882 dispatching operation (only its wrapper may be).
23883 (Build_Derived_Record_Type): In case of tagged private types that
23884 implement interfaces add derivation of predefined primitive
23886 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
23887 by two parameters that are used in case of derivation from abstract
23888 interface types: No_Predefined_Prims is used to avoid the derivation
23889 of predefined primitives from the interface, and Predefined
23890 Prims_Only is used to complete the derivation predefined primitives
23891 in case of private tagged types implementing interfaces.
23892 Fix typo in comments
23893 (Find_Interface_In_Descendant): Protect the frontend against
23894 wrong code with large circularity chains.
23895 (Is_Private_Overriding): Add support for entities overriding interface
23896 subprograms. The test failed because Entities associated with overriden
23897 interface subprograms are always marked as hidden (and used to build
23898 the secondary dispatch table); in this case the overriden entity is
23899 available through the field abstract_interface_alias (cf. override_
23900 dispatching_operation)
23901 (Access_Definition): Set the scope of the type to Current_Scope for the
23902 case of a function with an anonymous access result type.
23903 (Access_Subprogram_Declaration): Handle creation of the type entity for
23904 an access-to-function type with an anonymous access result.
23905 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
23906 in handling for N_Access_Function_Definition.
23907 (Analyze_Subtype_Declaration): Modify the text of error message.
23908 (Derived_Type_Declaration): Modify the text of error message.
23909 (Process_Subtype): Modify the text of error message plus cleanup
23910 of one redundant error message.
23911 (Analyze_Component_Declaration): Code cleanup.
23912 (Analyze_Object_Declaration): Code cleanup.
23913 (Analyze_Subtype_Declaration): Propagate the null-exclusion
23914 attribute in case of access types. Code cleanup.
23915 (Array_Type_Declaration): Code cleanup.
23916 (Process_Discriminants): Create the new null-excluding itype
23917 if required. Code cleanup.
23918 (Process_Subtype): Create the new null-excluding itype if
23919 required. Code cleanup.
23920 (Build_Derived_Record_Type): Code cleanup to avoid calling
23921 twice the subprogram derive_subprograms in case of private
23922 types that implement interfaces. In this particular case the
23923 subprogram Complete_Subprograms_Derivation already does the
23924 job associated with the second call.
23926 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
23927 conversion to the full view when generating an operation for a
23928 discriminant whose type may currently be private.
23930 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23931 Javier Miranda <miranda@adacore.com>
23933 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
23934 V (Obj.F), the rewriting does not involve the indexed component, but
23935 only the selected component itself.
23936 Do not apply the transformation if the analyzed node is an actual of a
23937 call to another subprogram.
23938 (Complete_Object_Operation): Retain the entity of the
23939 dispatching operation in the selector of the rewritten node. The
23940 entity will be used in the expansion of dispatching selects.
23941 (Analyze_One_Call): Improve location of the error message associated
23943 (Analyze_Selected_Component): No need to resolve prefix when it is a
23944 function call, resolution is done when parent node is resolved, as
23946 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
23947 when attempting to resolve a call transformed from its object notation.
23948 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
23949 of the argument list for each interpretation of the operation.
23950 (Try_Object_Operation): The designated type of an access parameter may
23951 be an incomplete type obtained through a limited_with clause, in which
23952 case the primitive operations of the type are retrieved from its full
23954 (Analyze_Call): If this is an indirect call, and the return type of the
23955 access_to_subprogram is incomplete, use its full view if available.
23957 2005-09-01 Javier Miranda <miranda@adacore.com>
23958 Gary Dismukes <dismukes@adacore.com>
23960 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
23961 access types the null-exclusion and access-to-constant attributes must
23963 (Analyze_Return_Statement): When the result type is an anonymous access
23964 type, apply a conversion of the return expression to the access type
23965 to ensure that appropriate accessibility checks are performed.
23966 (Analyze_Return_Type): For the case of an anonymous access result type,
23967 generate the Itype and set Is_Local_Anonymous_Access on the type.
23968 Add ??? placeholder for check to disallow returning a limited object
23969 in Ada 2005 unless it's an aggregate or a result of a function call.
23970 Change calls from Subtype_Mark to Result_Definition.
23971 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
23972 Result_Definition in call to Make_Function_Specification.
23973 (Build_Body_To_Inline): Change Set_Subtype_Mark to
23974 Set_Result_Definition.
23975 (Make_Inequality_Operator): Change formal Subtype_Mark to
23976 Result_Definition in call to Make_Function_Specification.
23977 (Process_Formals): Create the new null-excluding itype if required.
23978 (New_Overloaded_Entity): For an entity overriding an interface primitive
23979 check if the entity also covers other abstract subprograms in the same
23980 scope. This is required to handle the general case, that is, overriding
23981 other interface primitives and overriding abstract subprograms inherited
23982 from some abstract ancestor type.
23983 (New_Overloaded_Entity): For an overriding entity that comes from
23984 source, note the operation that it overrides.
23985 (Check_Conformance, Type_Conformant): Addition of one new formal
23986 to skip controlling formals in the analysis. This is used to
23987 handle overloading of abstract interfaces.
23988 (Base_Types_Match): Add missing case for types imported from
23989 limited-with clauses
23990 (New_Overloaded_Entity): Add barrier to protect the use of
23991 the "alias" attribute.
23993 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23995 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
23996 verify that the procedure and the entry are mode conformant.
23997 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
23998 as a different operator, which is often a cut-and-paste error.
24000 2005-09-01 Javier Miranda <miranda@adacore.com>
24001 Ed Schonberg <schonberg@adacore.com>
24003 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24004 used in controlling parameters exclude null because it is necessary to
24005 read the tag to dispatch, and null has no tag.
24006 (Override_Dispatching_Operation): If the previous operation is inherited
24007 from an interface, it becomes hidden and does not participate in later
24010 2005-09-01 Javier Miranda <miranda@adacore.com>
24011 Ed Schonberg <schonberg@adacore.com>
24012 Gary Dismukes <dismukes@adacore.com>
24014 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24015 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24016 the expander will generate the corresponding run-time check to evaluate
24018 (Resolve_Call): Check for legal type of procedure name or prefix that
24019 appears as a trigger in a triggering alternative.
24020 (Valid_Conversion): If expression is ambiguous and the context involves
24021 an extension of System, remove System.Address interpretations.
24022 (Resolve_Qualified_Expression): Reject the case of a specific-type
24023 qualification applied to a class-wide argument. Enhance comment
24024 to explain checking of Original_Node.
24025 (Resolve_Type_Conversion): The location of the error message was not
24026 general enough to handle the general case and hence it has been removed.
24027 In addition, this patch improves the text of the message.
24028 (Resolve_Type_Conversion): Add missing support for access to interface
24030 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24031 do not expand if the expression is the actual in a call, because proper
24032 expansion will take place when the call itself is expanded.
24033 (Resolve_Allocator): If the context is an unchecked conversion, the
24034 allocator inherits its storage pool, if any, from the target type of
24037 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24038 Javier Miranda <miranda@adacore.com>
24040 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24041 inherited interface operation that has an implementation, use the
24042 implementation to avoid spurious ambiguities.
24043 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24044 use the Corresponding_Record_Typ attribute to look for the interface
24045 because it is set by the expander (and hence it is not always
24046 available). For this reason we traverse the list of interfaces
24047 (available in the parent of the concurrent type).
24048 (Interface_Present_In_Ancestor): Handle entities from the limited view
24050 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24052 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24053 from the list of required components.
24054 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24055 primitive procedure of a limited interface with a controlling first
24057 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24059 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24060 capture if it is generated in the second operand of a short-circuit
24062 Do not capture values for variables with address clauses.
24063 (Is_Object_Reference): Treat a function call as an object reference only
24064 if its type is not Standard_Void_Type.
24066 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24068 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24069 to a variable that is statically known to be constant.

24072 Robert Dewar <dewar@adacore.com>

24081 Document that bounds of result of Base_Name match the input index
24083 Add documentation on environment variable syntax for Expand_Path
24085 * gnat_ugn.texi: Update documentation to include mention of -m switches
24086 Document new treatment of wide characters in max line length
24088 Remove -gnatL/-gnatZ switches, no longer used.
24089 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24092 * gnat_rm.texi: Add doc for two argument form of pragma
24093 Float_Representation.
24094 Add documentation for pragma No_Strict_Aliasing
24095 Add note that explicit component clause overrides pragma Pack.

24851 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
24852 longer protected objects. They have been replaced by lower-level
24853 suspension objects made up by a mutex and a condition variable (or
24854 their equivalent given a particular OS) plus some internal data to
24855 reflect the state of the suspension object.
24856 (Initialize, Finalize): Add this initialization procedure for
24857 Suspension_Object, which is a controlled type.
24858 (Finalize): Add the finalization procedure for Suspension_Object,
24859 which is a controlled type.
24861 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
24862 Ada.Synchronous_Task_Control because there is no longer a need for a
24863 VxWorks specific version of this package. Target dependencies
24864 has been moved to System.Task_Primitives.Operations.
24866 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
24868 (InitializeCriticalSection, EnterCriticalSection,
24869 LeaveCriticalSection, DeleteCriticalSection): Replace the type
24870 pCriticalSection by an anonymous access type so that we avoid problems
24871 of accessibility to local objects.

24877 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
24878 set the environment task mask here.
24879 (Current_State): Add this function that returns the state of the
24881 (Set_False): Add this procedure that sets the state of the suspension
24883 (Set_True): Add this procedure that sets the state of the suspension
24884 object to True, releasing the task that was suspended, if any.
24885 (Suspend_Until_True): Add this procedure that blocks the calling task
24886 until the state of the object is True. Program_Error is raised if
24887 another task is already waiting on that suspension object.
24888 (Initialize): Add this procedure for initializing the suspension
24889 object. It initializes the mutex and the condition variable which are
24890 used for synchronization and queuing, and it sets the internal state
24892 (Finalize): Add this procedure for finalizing the suspension object,
24893 destroying the mutex and the condition variable.

24898 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
24899 which provides a low-level abstraction (using operating system
24900 primitives) for Ada.Synchronous_Task_Control.
24901 This object is made up by a mutex (for ensuring mutual exclusion), a
24902 condition variable (for queuing threads until the condition is
24903 signaled), a Boolean (State) indicating whether the object is open,
24904 and a Boolean (Waiting) reflecting whether there is a task already

24913 (Setup_Interrupt_Mask): New procedure.
24915 * s-intman-vxworks.ads, s-intman-vxworks.adb: Update comments.
24917 * s-inmaop.ads (Setup_Interrupt_Mask): New procedure
24919 * s-interr.adb: Add explicit call to Setup_Interrupt_Mask now that
24920 this is no longer done in the body of s-taprop
24921 (Server_Task): Explicitely test for Pending_Action in case
24922 System.Parameters.No_Abort is True.
24924 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
24925 is no longer done in the body of s-taprop

25098 * exp_ch5.adb (Expand_N_Return_Statement): When a function's result
25099 type is a class-wide type, emit a run-time check that the accessibility

25170 type derivation of private tagged types implementing interfaces.
25171 In this case some interface primitives may have been overriden

25237 (Expand_Call, Freeze_Subprogram): Modified to give support to abstract
25239 (Expand_Inlined_Call): Mark temporary generated for the return value as
25240 internal, so that no useless scalar normalization is generated for it.

25261 * i-cpp.ads, i-cpp.adb:
25262 This package has been left available for compatibility with previous
25263 versions of the frontend. As part of the new layout this is now a

25307 (Analyze_Subprogram_Body): Undo the previous work.
25308 (Analyze_Procedure_Call): If the call has the form Object.Op, the

25317 access to subprograms must be recursive.
25318 (Is_Unchecked_Conversion): Improve the test that recognizes
25319 instantiations of Unchecked_Conversion, and allows them in bodies that
25320 are to be inlined by the front-end. When the body comes from an
25321 instantiation, a reference to Unchecked_Conversion will be an
25322 Expanded_Name, even though the body has not been analyzed yet.

25342 in the case where the target type is an anonymous access type of an
25343 object or component (that is, when Is_Local_Anonymous_Access is true).
25344 Prevent the special checks for conversions of access discriminants in
25345 the case where the discriminant belongs to a nonlimited type, since
25346 such discriminants have their accessibility level defined in the same
25347 way as a normal component of an anonymous access type.
25348 (Resolve_Allocator): When an allocator's designated type is a class-wide
25349 type, check that the accessibility level of type given in the
25350 allocator's expression or subtype indication is not statically deeper

25365 weakened in Ada 2005.
25366 Call to obsolescent subprogram is now considered to be a violation of
25367 pragma Restrictions (No_Obsolescent_Features).
25368 (Check_Direct_Boolean_Operator): If the boolean operation has been
25369 constant-folded, there is nothing to check.
25370 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25371 check on possible violation of restriction No_Direct_Boolean_Operators
25372 until after expansion of operands, to prevent spurious errors when

25398 * atree.adb: (Elist*): Protect against uninitialized field
25400 2005-06-14 Ed Schonberg <schonberg@adacore.com>
25402 * checks.adb (Install_Null_Excluding_Check): Do not generate checks
25403 for an attribute reference that returns an access type.
25404 (Apply_Discriminant_Check): No need for check if (designated) type has
25405 constrained partial view.
25407 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
25408 both bound checks, rather than a conjunction.
25409 (Insert_Valid_Check): If the expression is an actual that is an indexed
25410 component of a bit-packed array, force expansion of the packed element

26377 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26378 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26379 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26380 analyzed if expansion is disabled (which could otherwise cause spurious
26381 error messages if expansion has been disabled due to previous
26382 (unrelated) errors).
26384 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26385 is disabled, the entity denoted by the argument is the access type
26386 itself, not an underlying record type, so there is no need to go back
26387 to the Corresponding_Remote_Type.

26393 expand a call to an instance of
26394 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the

26396 check is also generated, to ensure that the tag passed to the instance
26397 denotes a type in the class.
26398 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26399 of Name_Generic_Dispatching_Constructor.
26401 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26402 05 unit for AI-260-02).

26417 generic formal subprogram association for an abstract formal subprogram.
26418 Check that the attribute is a primitive stream attribute (and not
26419 a class-wide stream attribute) and then rewrite the attribute name
26420 as the name of the appropriate compiler-generated stream primitive.

26431 * freeze.adb (Freeze_Record_Type): If the type of the component is an
26432 itype whose parent is controlled and not yet frozen, do not create a
26433 freeze node for the itype if expansion is disabled.
26435 2005-03-29 Vincent Celier <celier@adacore.com>
26437 * make.adb (Gnatmake): Don't fail if the main project file is declared
26438 as having no Ada sources. Do not display message "no sources to
26439 compile" in quiet output.
26441 2005-03-29 Doug Rupp <rupp@adacore.com>
26443 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26459 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26460 rather than proceed ahead using a junk attribute name.
26462 2005-03-29 Vincent Celier <celier@adacore.com>
26464 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26466 * prj-part.adb (Parse_Single_Project): Set the location of a project
26467 on its defining identifier, rather than on the reserved word "project".
26469 * prj-proc.adb (Expression): Adapt to the fact that default of external
26470 references may be string expressions, not always literal strings.
26471 (Recursive_Process): Set Display_Name equal to Name
26472 when Location is No_Location, that is when there is no actual file.
26473 Get the Display_Name of the project from the source, when it is not a
26475 (Process): Use the Display_Name in error messages
26477 * prj-strt.adb (External_Reference): Allow default to be string
26478 expressions, not only literal strings.
26480 2005-03-29 Vincent Celier <celier@adacore.com>

26491 equivalent type for a remote access-to-subprogram type, go back to the
26492 original RAS entity when displaying an error message, so the casing is
26493 the original source casing.

26497 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
26500 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26502 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26503 subtype if code is being pre-analyzed, to prevent un-expanded
26504 references to protected formals, among others.
26505 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26506 interpretation that can be a call, include the result of the call as a
26507 possible interpretation of the dereference.
26509 * sem_ch5.adb (Process_Bounds): Determine type of range by
26510 pre-analyzing a copy of the original range, and then analyze the range
26511 with the expected type.
26513 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26514 with an overloaded prefix where not all interpretations yield an
26515 access to subprogram, do not rewrite node as a call.
26516 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26517 the node as a call once the context identifies the interpretation of
26518 the prefix whose call yields the context type.
26519 (Valid_Conversion): For the case of a conversion between
26520 local access-to-subprogram types, check subtype conformance using
26521 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26522 detailed error message.

26526 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26527 indicator, indicate that the formal can never be null.
26528 (Process_Formals): If a formal has a non_null indicator, insert the
26529 resulting subtype immediately before the enclosing subprogram decl,
26530 and not at the beginning of the corresponding declarative part, to
26531 prevent access before elaboration (Ada2005).

26655 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
26656 subprogram determines whether a default implementation exists for a
26657 given stream attribute.
26658 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
26659 Determine whether to generate a default implementation for each stream
26660 attribute separately, as this depends on the specific attribute.
26662 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
26663 limited extension where a stream attribute is missing for a limited
26664 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

27197 These subprogram have been removed because the attribute
27198 Task_Body_Procedure has been moved to the corresponding task type
27199 or task subtype entity to leave a field free to store the list
27200 of interfaces implemented by a task (for AI-345)

27265 expression to the type of the object when the object is constant.
27266 Reverse defer_debug_incomplete_list before traversing it, so that trees
27267 are processed in the order at which they were added to the list. This
27268 order is important when using the stabs debug format.
27269 If we are deferring the output of debug information, also defer this
27270 output for a function return type.

27315 Comes_From_Generic, to recognize accurately that the parent type in a
27316 derived type declaration can be traced back to a formal type, because
27317 it is one or is derived from one, or because its completion is derived
27319 (Constrain_Component_Type): If component comes from source and has no
27320 explicit constraint, no need to constrain in in a subtype of the
27322 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27323 Minor change to propagate Is_Ada_2005 flag
27325 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27326 Expansion_Delayed is False.
27327 (assoc_to_constructor): Ignore fields that have a
27328 Corresponding_Discriminant.
27329 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27330 function returns "by target", dereference the target pointer using the
27331 type of the actual return value.
27332 <all>: Be prepared for a null gnu_result.
27333 (processed_inline_subprograms): Check flag_really_no_inline
27334 instead of flag_no_inline.
27335 (set_second_error_entity): Remove unused function.
27336 (gnat_to_gnu, case N_Selected_Component): Call
27337 gnat_to_gnu_field_decl.

27341 Ed Schonberg <schonberg@adacore.com>
27342 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27344 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27345 Must_Be_Byte_Aligned for cases where we do not need to use a
27346 System.Pack_nn unit.
27348 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27350 Needed now that we do some processing for IN parameters as well. This
27351 may well fix some unrelated errors.
27352 (Expand_Call): Handle case of unaligned objects (in particular those
27353 that come from packed arrays).
27354 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27355 renamed entity is an inherited operation, re-expand the call using the
27356 original operation, which is the one to call.
27357 Detect attempt to inline parameterless recursive subprogram.
27358 (Represented_As_Scalar): Fix to work properly with private types
27359 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27360 accurate estimate. Yields True in far fewer cases than before,
27361 improving the quality of code that depends on this test.
27363 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27364 over both visible and private declarations to remove them from tree,
27365 and mark subprograms declared in package as eliminated, to prevent
27366 spurious use in subsequent compilation of generic units in the context.
27368 * exp_util.ads: Minor cleanup in variable names
27370 * sem_eval.ads, sem_eval.adb: Minor reformatting
27371 (Compile_Time_Known_Bounds): New function
27373 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27375 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27376 determining whether an unchecked conversion is needed for the argument
27377 of an initialization call.
27379 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27381 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27382 that appears in the instantiation rather than the internal subtype
27383 generated in the wrapper package, to avoid anomalies in gigi when the
27384 target is derived from a private type whose full view is an access type.
27386 2005-03-15 Robert Dewar <dewar@adacore.com>
27388 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27390 Add documentation to replace the use of this flag
27391 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27394 2005-03-15 Thomas Quinot <quinot@adacore.com>
27396 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27397 here from exp_attr so it can be shared between exp_attr and exp_dist.
27398 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27399 all TSS names, not a subset thereof, and the previous name introduced
27400 an unnecessarily confusion that a distinction might exist between
27401 "OK" TSS names and some "not OK" TSS names.
27403 2005-03-15 Doug Rupp <rupp@adacore.com>
27405 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27408 2005-03-15 Pascal Obry <obry@adacore.com>
27409 Eric Botcazou <ebotcazou@adacore.com>
27413 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27414 when IN_RTS. This is to work around a bootstrap path problem.
27416 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27417 table and pass it to __gnat_install_SEH_handler().
27418 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27420 * lang.opt: Fix specification of -fRTS=.
27422 2005-03-15 Doug Rupp <rupp@adacore.com>
27423 Bernard Banner <banner@adacore.com>
27424 Vincent Celier <celier@adacore.com>
27425 Arnaud Charlet <charlet@adacore.com>
27428 This change works fine when gnatlib is built from the gcc directory,
27429 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27430 is not passed to ada/Makefile.in, so more work is needed by a
27431 Makefile/configure expert.
27433 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27434 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27435 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27437 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27438 Run ranlib on libgccprefix.a
27439 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27440 (ADA_INCLUDE_SRCS): Split Ada packages.
27442 2005-03-15 Robert Dewar <dewar@adacore.com>
27444 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27446 * impunit.adb: Add GNAT.UTF_32
27448 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27450 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27451 now uses GNAT.UTF_32).
27453 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27454 capabilities for categorizing characters using Unicode categories
27456 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27458 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27459 instantiation that has been rewritten as a package body, retrieve spec
27460 to generate proper name for implicit_with_clause.
27461 (Install_Parents): Recognize a parent that is an instantiation but has
27462 been rewritten as a package declaration during analysis.
27464 2005-03-15 Javier Miranda <miranda@adacore.com>
27465 Ed Schonberg <schonberg@adacore.com>
27467 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27468 parameter reported some error we immediately return. This improves the
27469 behaviour of the frontend in case of errors.
27470 (Install_Parent, Remove_Parent): Introduce new flag
27471 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27472 ancestor of a generic child unit, when the child is being instantiated.
27473 (Inline_Instance_Body): If we are compiling the private
27474 part or the body of a child unit, restore the proper visibility of the
27475 parents after compiling the instance body.
27477 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27478 Javier Miranda <miranda@adacore.com>
27481 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27482 of a private type, in which case it is underlying_type that denotes
27483 the proper task. Also modified to use the new entity attribute
27484 that is directly available in the task type and task subtype entities
27485 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27486 arrays when other dimensions than the first are constrained by
27487 discriminants of an enclosing record.
27488 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27489 a combination of indexed and selected components, find ultimate entity
27490 and generate the appropriate reference for it, to suppress spurious
27492 (Note_Possible_Modification): If an entity name has no entity, return.
27493 (Is_Variable): A function call never denotes a variable.
27494 (Requires_Transient_Scope): For record types, recurse only on
27495 components, not on internal subtypes that may have been generated for
27496 constrained components.
27498 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27500 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27501 Eliminated as candidates for resolution. Both efficient, and avoids
27502 anomalies with operators declared in deleted code.
27503 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27504 expansion is disabled (as when compiling a generic) to prevent spurious
27505 warnings on prefixes of selected components.
27507 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27509 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27510 attached to a list before checking whether it appears in the private
27511 declarations of the current package.
27512 (Make_Inequality_Operator): Insert declaration in proper declarative
27513 list rather than just setting the Parent field, so that
27514 Is_Private_Declaration can handle it properly.
27516 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27518 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27519 a renaming a body, check that the renamed subprogram in not intrinsic.
27520 (Find_Direct_Name): If several use_visible entities hide
27521 each other, and the context is a predefined file compiled through
27522 rtsfind, keep only the entity that comes from a predefined file.
27524 2005-03-15 Geert Bosch <bosch@adacore.com>
27526 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27527 long float padding to also cover AMD64 and IA64.
27529 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27531 * s-imgwch.adb: Add with and use of Interfaces.
27532 (Img_Wide_Character): Change type of Val to Unsigned_16.
27533 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27535 2005-03-15 Matthew Gingell <gingell@adacore.com>

27580 Cyrille Comar <comar@adacore.com>
27581 Sergey Rybin <rybin@adacore.com>
27583 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
27584 too specific and long-winded to be appropriate for the GNAT User's
27586 Warn about use of GCC switches not documented in the GNAT User's Guide,
27587 as these may cause generated code to not conform to Ada semantics.
27588 Remove mention of -gdwarf-2 for sparc64, since this is now the default.

27847 and Tok_Synchronized.
27849 * sem_res.adb (Resolve_Actuals): Change error messages to refer to
27850 "dispatching" rather than "primitive" operations, since dispatching

27854 (Resolve_Slice): If the prefix is an access to an unconstrained array,
27855 compute the actual subtype of the designated object to impose the proper
27857 (Resolve_Selected_Component): Do not insert an access check if the
27858 prefix is an access type: such a node is expanded into an explicit
27859 dereference, on which the access check is performed anyway. Removes
27860 expensive duplicate checks.
27861 (Resolve_Call): Use new flag Is_Obsolescent and field
27862 Obsolescent_Warning so that pragma Obsolescent works on library
27864 Add support for wide wide character type
27865 (Resolve_Allocator): Replace the error message on wrong null-exclusion
27866 value by a warning message.
27867 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
27868 as fixed-point, and one of the operands is non-static and universal, it
27869 can only be an illegal exponentiation operation, in which case there is
27870 no real value to retrieve.
27872 * exp_strm.adb: Add support for wide wide character type
27873 (Build_Elementary_Input_Call): Compute the size of the stream element by

27913 (Unit_Declaration_Node): Ditto.
27914 (Is_Variable_Prefix): For the case of an indexed component whose prefix
27915 has a packed array type, the prefix has been rewritten into a type

27921 * stringt.ads, stringt.adb: Handle full UTF-32 range.
27922 Remove ["0A"] from comment, since it can look like a line terminator.
27923 Currently we don't permit this, but this is under discussion by the
27924 ARG, and it is easy enough to use a different example.
27926 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
27927 handling UTF-32 encoding for wide wide character.

27985 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
27986 describing the new layout.
27987 (Dispatch_Table): The expander computes the actual array size, allocates
27988 the Dispatch_Table record accordingly, and generates code that displaces
27989 the base of the record after the Typeinfo_Ptr component. The access to
27990 these components is done by means of local functions.
27991 (Offset_To_Top): New function.
27992 (Typeinfo_Ptr): New function.
27993 (Get_TSD): Modified to access the new position of the TSD.

28004 N_Formal_Subtype_Declaration (which is now a subtype).
28005 (Analyze_Formal_Subprogram): Add handling for
28006 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28007 dispatching, setting the controlling status of the formal parameters
28008 and result, and issuing an error if there is no controlling type for
28009 the formal subprogram.
28010 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28011 which is an unclean use of that field, we set the new field
28012 Corresponding_Formal_Spec to make the formal subprogram available to
28013 processing in Analyze_Subprogram_Declaration.
28014 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28015 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type

28020 abstract formal subprograms in error check for functions returning
28021 abstract types. Set scope of new designator for

28023 body for nested subprograms, before full analysis of said body.
28024 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28025 subprogram only if inner one comes from source.
28026 (Analyze_Function_Call): If the call is given in object notation, the
28027 analysis of the name rewrites the node and analyzes it with the proper
28028 argument list. After analyzing the name, if the call has been rewritten
28029 and the result type is set, no further analysis is needed.
28030 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28031 mark in function specification, in a context where the formals are
28032 visible and hide outer homographs.
28034 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28035 as the tagged type for the cases of abstract formal subprograms and
28036 renamings of those. Clean up spec comments.
28037 (Check_Dispatching_Context): Add error message to indicate "abstract
28038 procedure", covering the case of a call to a formal abstract procedure
28039 that has statically tagged operands.
28040 (Check_Dispatching_Call): Check for the case of an actual given by
28041 a tag-indeterminate function call whose type is an ancestor of the
28042 containing call's associated tagged type. This situation can occur
28043 for inherited primitives with function defaults. In this case we
28044 use the tagged type's tag directly as the controlling argument for
28046 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28048 * sprint.adb (Sprint_Node_Actual): Split
28049 N_Formal_Subprogram_Declaration into two alternatives for the new

28125 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28126 on the field if Pragma Component_Alignment (Storage_Unit).
28127 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28128 side-effects as if it were a constant; also make SAVE_EXPR to protect

28148 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28149 component of an array of arrays in an assignment context, and the
28150 aggregate has component associations that require sliding on
28151 assignment, force reanalysis of the aggregate to generate a temporary
28152 before the assignment.
28153 (Must_Slide): Make global to the package, for use in Gen_Assign.
28155 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28157 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28158 unchecked union with no inferable discriminants, return a
28159 Raise_Program_Error node, rather than inserting it at the point the
28161 (Expand_Record_Equality, Component_Equality): Handle properly the case
28162 where some subcomponent is an unchecked union whose generated equality
28163 code raises program error.

28171 Arnaud Charlet <charlet@adacore.com>
28173 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28174 address of the exception registration. The Win32 version of this
28175 routine calls __gnat_install_SEH_handler() to initialize the SEH
28176 (Structured Exception Handling) handler.
28177 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28178 SEH (Structured Exception Handling) now.
28179 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28180 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28181 preprocessor condition protecting the call to the extra eh setup
28182 subprogram, which is only available for the ppc target.

28196 Update copyright notice.
28198 * s-tassta.adb (Task_Wrapper): Declare the exception registration

28228 2005-02-09 Vincent Celier <celier@adacore.com>
28230 * prj-makr.adb (Process_Directory): Put file name in canonical case
28231 before matching against the patterns.
28232 If gnatname has been invoked as <prefix>-gnatname
28233 then invoke the compiler as <prefix>-gcc, not just "gcc".
28235 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28237 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28238 with expansion disabled. The actual subtype is needed among other
28239 places when the selected component appears in the context of a loop
28240 bound, and denotes a packed array.
28241 (Operator_Check): Always use the first subtype in the
28242 error message, to avoid the appearance of internal base types.
28243 (Transform_Object_Operation): Copy each actual in full
28244 to the parameter associations of the constructed call, rather than
28245 using the shallow copy mechanism of New_Copy_List. This ensures that
28246 the chaining of named associations is done properly.
28247 (Complete_Object_Operation): Rewrite node, rather than
28248 replacing it, so that we can trace back to the original selected
28251 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28252 and calls that use object notation, if the called function is not
28253 declared in a withed unit, place the elaboration constraint on the
28254 unit in the context that makes the function accessible.
28255 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28256 imposes an elaboration constraint between two packages.
28258 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28260 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28261 views of a private type after handling its private dependents, to
28262 maintain proper stack discipline between entry and exit from the

28278 recursion warnings when compiled with -gnatdm.
28280 2005-02-09 Robert Dewar <dewar@adacore.com>
28282 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28283 Slight fix to documentation of -gnaty with no parameters

29029 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
29030 fields claimed addressable still have to be bitfields. Use
29031 value_factor_p instead of a raw binop construction to check for the
29032 position's alignment.

29041 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29042 with an implicit dereference as its prefix, use
29043 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29045 prefix is generated, if appropriate.
29047 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29048 dereference is rewritten to an explicit one, generate a reference to
29049 the entity denoted by its prefix using the original prefix node, so

29051 access value, if appropriate.
29053 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29054 emitting 'assigned but never read' warning on a variable on the basis

29070 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29071 subprogram which is Imported with convention Intrinsic if an
29072 External_Name argument is specified.
29073 (Process_Import_Or_Interface): Properly diagnose link name argument.
29074 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

29099 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29100 PCS-specific part of Add_Stub_Type.

29130 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29131 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29132 the body, to ensure that warnings are properly emitted for each accept
29133 statement of a given task entry.

29155 (Remove_Next_Debug): Same fix
29157 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
29158 maintain back pointers now, though we did not used to, and comments

29165 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29166 used to record an implicit dereference as a read operation on its
29167 prefix when operating under -gnatc. Necessary to avoid spurious
29168 'variable assigned but never read' warnings in that mode.
29169 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29170 is a non-overloaded implicit dereference, call the above subprogram to
29171 ensure proper recording of references.
29173 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29175 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

29225 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29226 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29227 and -eit to -ept. Added qualifier

29236 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29237 internal implementation unit GNAT.Sockets.Thin,
29238 as their usage for sockets is non-portable (using the read and write

29284 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
29287 2004-11-18 Olivier Hainque <hainque@adacore.com>
29289 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
29290 address of which may be used to represent "others" and "all others"
29291 choices in exception tables, instead of the current harcoded
29292 (void *)0 and (void *)1.
29293 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29295 * gigi.h (others_decl, all_others_decl): New decls representing the
29296 new Others_Value and All_Others_Value objects.
29297 (struct attrib): Rename "arg" component as "args", since GCC expects a
29298 list of arguments in there.
29300 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29301 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29304 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29305 others_decl and all_others_decl instead of hardcoded dummy addresses
29306 to represent "others" and "all others" choices, which is cleaner and
29307 more flexible with respect to the possible eh pointer encoding policies.
29309 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29310 (process_attributes): Account for the naming change of the "args"
29311 attribute list entry component.
29313 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29314 cumulating attributes for different entities into a single list.
29315 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29316 attributes for the current entity and propagate first subtype
29317 attributes to other subtypes.
29318 <E_Procedure>: Attribute arguments are attr->args and not
29319 attr->arg any more.
29320 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29321 argument provided, as this is what GCC expects. Use NULL_TREE instead
29324 2004-11-18 Robert Dewar <dewar@adacore.com>
29326 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
29327 Minor reformatting througout (including new function specs)
29328 Add ??? comments asking for clarification.
29330 2004-11-18 Thomas Quinot <quinot@adacore.com>
29332 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
29333 incomplete duplicate implementation of this subprogram from butil.
29335 2004-11-18 Thomas Quinot <quinot@adacore.com>
29337 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
29338 procedures factors the common processing for building an RPC receiver
29339 for an RCI package or an RACW type.
29340 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
29341 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
29342 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
29344 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
29346 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
29348 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
29349 distribution subprogram identifiers that are either subprogram numbers
29351 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
29352 string distribution identifiers assigned to a given subprogram.
29353 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29354 (Add_RAS_Dereference_TSS): Add comments.
29355 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29356 is not referenced yet because it will be used by the PolyORB DSA
29358 (Insert_Partition_Check): Remove fossile code.
29359 (First_RCI_Subprogram_Id): Document this constant.
29360 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29362 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29363 replaced with calls to Get_Library_Unit_Name_String. Previously there
29364 were several instances of the same code in different locations in the
29365 compiler; this checkin completes the replacement of all of these
29366 instances with calls to a common subprogram.
29367 Minor reformatting.
29369 * sem_dist.adb: Remove comment noting that RPC receiver generation
29370 should be disabled for RACWs that implement RASs.
29371 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
29373 * sem_util.ads, sem_util.adb (Has_Stream): New function
29374 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
29375 qualified name of a library unit into the name buffer.
29376 (Note_Possible_Modification): Generate a reference only
29377 if the context comes from source.
29379 * snames.ads (PCS_Names): New subtype corresponding to names of
29380 supported implementations of the Partition Communication Subsystem
29381 (PCS) (i.e. the runtime library support modules for the distributed
29384 2004-11-18 Robert Dewar <dewar@adacore.com>
29385 Ed Schonberg <schonberg@adacore.com>
29387 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
29388 (Has_Rep_Pragma): New function
29389 (Has_Attribute_Definition_Clause): New function
29390 (Record_Rep_Pragma): Moved here from sem_ch13.adb
29391 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
29393 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
29395 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29396 (Expand_Pragma_Psect_Object): New procedure
29397 These procedures contain the revised and cleaned up processing for
29398 these two pragmas. This processing was formerly in Sem_Prag, but
29399 is more appropriately moved here. The cleanup involves making sure
29400 that the pragmas are properly attached to the tree, and that no
29401 nodes are improperly shared.
29403 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29404 pragmas to Exp_Prag, which is more appropriate.
29405 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29406 check for duplicates Remove use of Is_Psected flag, no longer needed.
29407 Use new Make_String_Literal function with string.
29409 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29410 that are functions return universal values, that have to be converted
29411 to the context type.
29412 Use new Make_String_Literal function with string.
29413 (Get_Stream_Convert_Pragma): New function, replaces the use of
29414 Get_Rep_Pragma, which had to be kludged to work in this case.
29416 * freeze.adb: Use new Has_Rep_Pragma function
29418 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29419 function with string.
29420 Use new Has_Rep_Pragma function.
29422 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29425 2004-11-18 Robert Dewar <dewar@adacore.com>
29427 * errout.ads, errout.adb: (First_Sloc): New function
29429 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29430 check (-gnatyx) instead of being included as a redundant construct
29433 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29434 Style_Check_Order_Subprograms.
29436 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29437 stylesw.adb: Add Style_Check_Xtra_Parens
29439 * usage.adb: Add line for -gnatyx (check extra parens)
29441 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29443 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29444 Robert Dewar <dewar@adacore.com>
29446 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29447 discriminant of a constrained subtype, analyze the copy of the
29448 corresponding constraint, because in some cases it may be only
29449 partially analyzed.
29450 Removes long-lived ??? comments.
29452 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29453 handled controlled or secondary-stack expressions within the
29454 iteration_scheme of a loop.
29456 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29457 bounds that may contain functions calls, to prevent memory leaks when
29458 the bound contains a call to a function that uses the secondary stack.
29459 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29460 generate temporaries for loop bounds that might contain function calls
29461 that require secondary stack and/or finalization actions.
29463 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29464 selected component and the selector is overloadable (not just a
29465 function) treat as function call, Analyze_Call will disambiguate if
29467 (Analyze_Selected_Component): Do not generate an actual subtype for the
29468 selected component if expansion is disabled. The actual subtype is only
29469 needed for constraint checks.
29470 (Analyze_Allocator): If restriction No_Streams is set, then do
29471 not permit objects to be declared of a stream type, or of a
29472 composite type containing a stream.
29474 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29475 No_Streams no longer prohibits with'ing this package.
29477 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29478 discriminants, but the parent base has unknown discriminants, there is
29479 no discriminant constraint to inherit. Such a discrepancy can arise
29480 when the actual for a formal type with unknown discriminants is a
29481 similar private type whose full view has discriminants.
29482 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29483 do not permit objects to be declared of a stream type, or of a
29484 composite type containing a stream.
29486 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29488 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29489 protected operations.
29491 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29492 generated name, it complicates decoding in gdb and hinders debugging
29493 of protected operations.
29494 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29495 flag for the protected entry barrier function.
29496 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29497 flag for the protected entry function.
29499 2004-11-18 Nicolas Setton <setton@adacore.com>
29501 * expect.c: Define __unix__ when __APPLE__ is defined.
29503 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29504 Darwin-specific section.
29506 * lang-specs.h: Change the placement of the %1 marker.
29507 Works around the fact that gcc adds -fPIC by default under Darwin.
29509 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29511 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29512 type of the object with the packed array type, set the Analyzed flag
29513 on the object if it is an entity or simple indexed component, to avoid
29514 spurious type errors.
29516 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29518 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29519 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29520 separate line from the version message.
29522 2004-11-18 Ed Falis <falis@adacore.com>
29524 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29526 (init_float): Eliminate initialization of floating point status for
29527 AE653. The instructions have no effect for vThreads.
29529 2004-11-18 Vincent Celier <celier@adacore.com>
29531 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29532 gnatbind is invoked with -shared.
29534 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29536 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29537 for Detect_Blocking which is redundant with the check done within the
29538 procedure Protected_Single_Entry_Call.
29539 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29540 Detect_Blocking which is redundant with the check done within the
29541 procedure Protected_Single_Entry_Call.
29543 2004-11-18 Vincent Celier <celier@adacore.com>
29545 * makegpr.adb (Compile): Put the compiling switches (in package
29546 Compiler and on the command line) immediately after "-c", instead of
29547 at the end of the command line invocation of the compiler, when
29548 compiling a non-Ada file.
29549 (Build_Global_Archive): When there is no need to rebuild the archive,
29550 set Global_Archive_Exists, so that the archive is passed to the linker
29553 2004-11-18 Robert Dewar <dewar@adacore.com>
29554 Sergey Rybin <rybin@adacore.com>
29557 Remove extra paren check from list of checks for redundant constructs
29558 Add documentation of new -gnatyx style check (check extra parens)
29559 Remove paragraph about gnatelim debug options.
29561 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29562 objects rather than forbidding dependencies on the package Ada.Streams.
29564 * sinfo.ads: Add ??? note that we should document pragmas passed to
29567 * g-expect.ads: Fix a few typos in the comments.
29569 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29571 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29574 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29576 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29578 2004-11-07 Andreas Schwab <schwab@suse.de>
29580 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29582 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29585 * Makefile.in (darwin): Set soext to .dylib.
29587 2004-10-26 Vincent Celier <celier@gnat.com>
29588 Thomas Quinot <quinot@act-europe.fr>
29590 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29591 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29592 there is no use of GNAT.Sockets.Constants.
29593 Remove remaining pragma Import for C_Write
29594 Remove C_Read and C_Write from internal implementation unit
29595 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29596 the read and write functions from the system runtime library is fine
29597 on UNIX but won't work under Windows).
29599 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29600 (Check_Selector): Use C_Recv instead of C_Read.
29601 Selectors are the GNAT.Sockets abstraction to perform a select()
29602 call on a set of descriptors. To allow abortion of an ongoing
29603 select operation, some data is written to a dedicated socket that
29604 is always monitored.
29605 Under Windows, the write and read library functions cannot operate
29606 on sockets, so we need to use send and recv instead, which is portable
29607 across all supported platforms.
29609 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29610 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29611 (using the read and write functions from the system runtime library is
29612 fine on UNIX but won't work under Windows).
29614 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29616 * mlib-tgt-darwin.adb: New file.
29618 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29619 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29620 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29621 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29624 * Makefile.in: Add support for building shared libraries under Darwin.
29625 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29626 the low level EH init subprogram to be called from __gnat_initialize.
29628 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29629 indicates which options to pass to the archive indexer.
29631 * mlib-utl.adb: Add support for calling ranlib with additional
29632 options. This is needed for instance under Mac OS X.
29633 (Ranlib_Options): New global variable, used to store the potential
29634 options to pass to ranlib.
29635 (Ar): Use Ranlib_Options when spawning ranlib.
29636 (Initialize): Set the value of ranlib option.
29638 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29640 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29641 instead of 8K, to reflect the real potential needs for stack-checking
29644 2004-10-26 Pascal Obry <obry@gnat.com>
29646 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29648 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29649 Windows only the initial thread stack size can be set so it is good to
29650 start we a low stack size.
29651 The OS will adjust the size as needed.
29653 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29654 Nicolas Setton <setton@act-europe.fr>
29656 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29657 "__unix__" instead of "unix".
29658 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29659 sections were just mistakenly ignored. The former is
29660 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29661 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29662 of hpux. This prevents an unwanted definition of the symbol
29663 convert_addresses in adaint.o.
29665 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29667 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29668 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29670 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29672 * a-filico.ads, a-filico.adb: fix incorrect header.
29674 2004-10-26 Javier Miranda <miranda@gnat.com>
29676 * a-ststio.ads: Fix typo in identifier
29678 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29680 * sem_ch4.adb: Minor reformatting.
29682 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29684 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29685 enabled, check the result of unary and binary operations when the
29686 expression is the right-hand side of an assignment.
29688 2004-10-26 Vincent Celier <celier@gnat.com>
29690 * clean.adb (Delete): Do not output warnings when in quiet output and
29691 not in verbose mode.
29692 (Force_Deletions): New Boolean flag, defaulted to False
29693 (Delete): Only delete a file if it is writable, and when
29694 Force_Deletions is True.
29695 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29696 (Usage): Line for new switch -f
29697 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29700 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29702 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29703 JM type only if its size matches that of the wrapper. When a size is
29704 prescribed and the field is not aliased, remove the wrapper of a JM
29705 type only if the size is not greater than that of the packed array.
29706 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29709 2004-10-26 Geert Bosch <bosch@gnat.com>
29711 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29712 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29713 (Pred): Implement in terms of Succ.
29715 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29717 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29718 unchecked conversion is safe for in-place use if the expression of the
29719 conversion is safe.
29720 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29721 be expandable in place even if the aggregate does not come from source.
29722 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29723 designated object of an allocator in place, rather than building it
29724 first on the stack. The previous scheme forces a full copy of the array,
29725 and may be altogether unsusable if the size of the array is too large
29726 for stack allocation.
29728 2004-10-26 Robert Dewar <dewar@gnat.com>
29730 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29731 compares if the component is atomic.
29733 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29734 array assignment if the component type is atomic.
29736 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29737 Eric Botcazou <ebotcazou@act-europe.fr>
29739 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29740 is aliased and is a by_reference type, do not pass by copy.
29741 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29742 detect whether the call is in the right side of an assignment or
29743 the expression of an object declaration. Recurse on component
29744 association within aggregates.
29745 Call it in the condition that determines whether the temporary is
29746 necessary for correct stack-checking.
29748 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29750 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29751 RACW_Type, used in the PolyORB version.
29752 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29753 version and the GARLIC version.
29755 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29756 Rename RCI_Info to RCI_Locator for better consistency between the
29757 GARLIC and PolyORB versions of the distributed systems annex.
29758 (DSA_Implementation_Name): This enumeration lists the possible
29759 implementations of the Partition Communication Subsystem for the
29760 Distributed Systems Annex (DSA). The three available implementations
29761 are the dummy stub implementation (No_DSA), and two versions based on
29762 two different distribution runtime libraries: GARLIC and PolyORB. Both
29763 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29765 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29768 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29769 between the GARLIC and PolyORB versions of the distributed systems
29771 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29773 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29775 * gnat1drv.adb: Suppress calling the back end when
29776 Frontend_Layout_On_Target is true.
29778 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29780 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29781 Set_Read_Only): New subprograms.
29782 These new routines allow the user to set or unset the Owner execute
29783 and Owner write permission flags on a file.
29785 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29786 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29788 2004-10-26 Matthew Gingell <gingell@gnat.com>
29790 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29792 2004-10-26 Pascal Obry <obry@gnat.com>
29794 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29795 memory before the faulting page we properly test the process read
29796 access for this address using appropriate Win32 routine.
29797 (HPUX sections): guard with "__hpux__" instead of "hpux".
29799 2004-10-26 Robert Dewar <dewar@gnat.com>
29801 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29802 entry parameter if pragma Unreferenced set, since we do not properly
29803 handle the case of multiple parameters.
29805 2004-10-26 Vincent Celier <celier@gnat.com>
29807 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29808 (Ada_Objects_Path.Add): For a library project, add to the object path
29809 the library directory only if there is no object directory or if the
29810 library directory contains ALI files.
29811 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29813 2004-10-26 Vincent Celier <celier@gnat.com>
29815 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29816 extension of library projects.
29818 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29819 path defaults to ".:<prefix>/lib/gnat".
29820 (Parse): For an extending all project, allow direct import of a project
29821 that is virtually extended.
29823 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29824 the specified name is directly imported, return its ID. Otherwise, if
29825 an extension of this project is imported, return the ID of the
29828 2004-10-26 Robert Dewar <dewar@gnat.com>
29830 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
29831 (Sub3): New procedure, used by Scaled_Divide
29832 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
29833 correct more than one instance of failure to propagate carries
29835 (Double_Divide): Handle overflow case of largest negative number
29836 divided by minus one.
29838 * s-arit64.ads (Double_Divide): Document that overflow can occur in
29839 the case of a quotient value out of range.
29842 2004-10-26 Robert Dewar <dewar@gnat.com>
29844 * s-bitops.adb (Bit_Eq): Remove redundant check.
29846 * s-bitops.ads: Minor comment updates
29847 Change some occurrences of Address to System.Address
29849 * s-carsi8.ads: Fix minor cut-and-paste error in comments
29851 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29853 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
29854 accessibility check to prefix that is a protected operation.
29856 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29858 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
29859 empty, post message on stub.
29861 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29862 Javier Miranda <miranda@gnat.com>
29864 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
29865 current instance appears within a unit that is directly in the context
29867 Used to determine whether the body of the instance should be analyzed
29868 immediately after its spec, to make its subprogram bodies available
29869 for front-end inlining.
29870 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
29871 constraint is not allowed on the component type (AARM 12.5.3(3))
29873 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29875 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
29876 'Storage_Pool): enhance, document & limit detection of non-sharable
29879 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
29881 * s-pooglo.ads: Add more documentation now that this pool is properly
29884 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29886 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
29887 or protected type with discriminants, do not constrain the
29888 corresponding record type if the subtype declaration has no
29889 discriminant constraints. This can be the case in source code, or in
29890 the subtype declaration created to rename an actual type within an
29893 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29895 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
29896 different kind of stub (possibly wrong name for file), do not check
29898 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
29899 includes call to some function that returns an unconstrained type, do
29902 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29904 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
29905 appear in the code for the main unit. Dependencies among units in the
29906 context of the main unit are established when those other units are
29907 compiled. Otherwise spurious elaboration constraints can generate
29908 incorrect elaboration circularities.
29910 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29911 Ed Schonberg <schonberg@gnat.com>
29913 * sem_util.adb (Is_Aliased_View): Defend against the case where this
29914 subprogram is called with a parameter that is not an object name. This
29915 situation arises for some cases of illegal code, which is diagnosed
29916 later, and in this case it is wrong to call Is_Aliased, as that might
29917 cause a compiler crash.
29918 (Explain_Limited_Type): Refine previous fix to include
29919 inherited components of derived types, to provide complete information.
29921 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
29922 is the prival for a protected object.
29923 It is necessary to mark this entity as a variable, in addition to
29924 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
29925 modified to avoid checking the Aliased flag on entities that are not
29926 objects. (Checking that flag for non-objects is erroneous and could
29927 lead to a compiler crash).
29929 2004-10-26 Robert Dewar <dewar@gnat.com>
29931 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
29932 X_Frac = 0.5, then we know that the number X must be positive.
29933 (Succ): Remove the same redundant test, and also fix the primary test
29934 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
29936 (Decompose): Add fuller comments to spec
29938 2004-10-26 Pascal Obry <obry@gnat.com>
29940 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
29941 validity (process must have read access). Set to 0 in all other cases.
29942 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
29943 violation on Win32.
29944 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
29945 segmentation violation.
29947 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29949 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
29950 whose type is a constructed subtype of an aliased object with an
29951 unconstrained nominal subtype, convert the actual to the constructed
29952 subtype before taking its address.
29954 2004-10-26 Vincent Celier <celier@gnat.com>
29956 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
29957 (Is_Path_Name_Case_Sensitive): New function
29959 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
29960 (Base_Name, Simple_Name, Current_Directory, Compose,
29961 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
29964 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29965 Vasiliy Fofanov <fofanov@act-europe.fr>
29966 Vincent Celier <celier@gnat.com>
29968 * gnat_ugn.texi: Generalize "finding memory problems" section into a
29969 "memory management issues" section and document some of the useful
29970 memory pools provided as part of the GNAT library.
29971 Remove "virtual" from declaration of A::method2 in
29972 the simple example of Ada/C++ mixed system.
29973 Library Projects may be virtually extended: their virtual extensions
29974 are not Library Projects.
29975 Added section on extending project hierarchies.
29977 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
29979 * adaint.c (__gnat_get_libraries_from_registry): Cast value
29981 (__gnat_portable_spawn): Remove const.
29983 * mingw32.h (MAXPATHLEN): Check for previous definition.
29985 2004-10-17 Matthias Klose <doko@debian.org>
29987 * gnatvsn.ads: Set gnat library version to 4.0.
29989 2004-10-05 Vincent Celier <celier@gnat.com>
29991 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
29993 2004-10-04 Laurent Guerby <laurent@guerby.net>
29996 * Makefile.in: Define and use RANLIB_FLAGS.
29998 2004-10-04 Pascal Obry <obry@gnat.com>
30000 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30001 other x86 platforms).
30003 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30005 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30006 in general and triggers stack alignment adjustment for thread entry
30007 points on targets where this is necessary.
30009 2004-10-04 Bernard Banner <banner@gnat.com>
30012 * Makefile.in: Add section for powerpc linux
30013 Add variant i-vxwork-x86.ads
30015 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30017 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30019 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30020 table registration calls when need be. Ensures no reference to the crt
30021 ctors symbol are issued in the SJLJ case, which avoids possible
30022 undefined symbol errors in the case of modules to be statically linked
30025 2004-10-04 Javier Miranda <miranda@gnat.com>
30027 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30028 in-line the code corresponding to subprogram Analyze_Actuals. In
30029 addition, analyze the actuals only in case of subprogram call.
30031 2004-10-04 Ed Falis <falis@gnat.com>
30033 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30035 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30037 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30038 in the documentation.
30040 2004-10-04 Robert Dewar <dewar@gnat.com>
30042 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30044 (Analyze_Block_Statement): Add circuitry to detect following dead code
30045 (Check_Unreachable_Code): Handle case of block exit
30047 2004-10-04 Robert Dewar <dewar@gnat.com>
30049 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30050 (XMatchD): Avoid warning for Logic_Error call
30052 2004-10-04 Robert Dewar <dewar@gnat.com>
30054 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30055 consider expressions buried within a procedure actual to be an actual.
30056 This caused some blowups with uses of packed slices within a procedure
30059 2004-10-04 Robert Dewar <dewar@gnat.com>
30061 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30062 longer need to be initialized to zero.
30063 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30064 initialized to zero.
30066 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30067 considered valid, even if the representation is modular. That's correct
30068 now that we no longer initialize packed modular arrays to zero.
30070 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30071 suffixes. These are now documented as the only cases in which the
30072 debugger ignores outer records.
30073 Previously, the spec allowed arbitrary suffixes for this purpose.
30074 Change name of LJM to JM for packed array pad records
30075 Create separate section on packed array handling, and add a whole new
30076 set of comments to this section describing the situation with packed
30077 modular types and justification requirements depending on endianness.
30079 2004-10-04 Robert Dewar <dewar@gnat.com>
30081 * a-except.adb: Add a comment for last change
30083 * einfo.ads: Minor spelling correction in comment
30085 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30087 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30090 * sem_util.ads: Minor comment update
30092 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30094 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30095 Inline_Always when in Configurable_Run_Time mode.
30097 * sem_prag.adb (Process_Convention): If entity is an inherited
30098 subprogram, apply convention to parent subprogram if in same scope.
30099 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30100 when in Configurable_Run_Time mode.
30102 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30104 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30105 class_wide type after component list has been inherited.
30107 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30109 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30110 Denotes_Previous_Actual, to handle properly the case of a private
30111 actual that is also the component type of a subsequent array actual.
30112 The visibility status of the first actual is not affected when the
30113 second is installed.
30114 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30115 make fully recursive the treatment of formals of packages declared
30117 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30118 the above on exit from an instantiation.
30119 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30120 current instantiation which is now complete.
30121 (Analyze_Package_Instantiation): No instantiated body is needed if the
30122 main unit is generic. Efficient, and avoid anomalies when a instance
30123 appears in a package accessed through rtsfind.
30125 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30127 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30128 do not generate a declaration for a temporary if the call is part of a
30129 library-level instantiation.
30131 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30133 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30134 searching for a limited component to flag.
30136 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30137 expansion of Input, to account for the fact that the implicit call
30138 generated by the attribute reference must freeze the user-defined
30139 stream subprogram. This is only relevant to 'Input, because it can
30140 appear in an object declaration, prior to the body of the subprogram.
30142 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30143 expansion can proceed and further errors uncovered.
30144 (Minor clean up): Fix cases of using | instead of \ for continuation
30147 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30149 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30151 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30152 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.

30155 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30156 specified alignment before validating size.
30157 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30158 stripped-down declaration for the type of the inner field when making
30161 * utils.c (finish_record_type): Do not compute the size in units
30162 incrementally. Instead compute it once for the rep clause case.
30163 Use gcc_assert and gcc_unreachable.
30165 2004-10-04 Vincent Celier <celier@gnat.com>
30167 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30169 (Is_Valid_Path_Name): Take '/' as a directory separator.
30171 2004-10-04 Vincent Celier <celier@gnat.com>
30173 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30174 (Extended_Project) only if Extended_Project is defined, to avoid
30176 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30178 (Parse_Single_Project): Ditto.
30180 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30181 Add_To_Project_Path for virtual projects.
30183 2004-10-04 Vincent Celier <celier@gnat.com>
30185 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30186 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30187 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30188 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30189 parameter Options_2.
30191 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30192 Build_Dynamic_Library with an empty Options_2.
30194 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30197 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30198 directory separator, if any.
30199 (Gprmake): Do not allow mains on the command line for library projects.
30200 Do not attempt to link when the project is a library project.
30201 (Library_Opts): New table to store Library_Options.
30202 (Build_Library): If Library_Options is specified, pass these options
30203 when building a shared library.
30205 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30207 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30208 the end of this procedure now that the unlock operation was inserted
30211 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30213 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30214 corresponding to the Preallocated_Stacks flags in System.
30215 (Get_Target_Parameters): Including the processing for
30216 Preallocated_Stacks.
30218 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
30219 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

30227 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30228 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30229 used to signal whether the compiler creates the required stacks and
30230 descriptors for the different tasks (when True) or it is done by the
30231 underlying operating system at run time (when False).
30232 It is initially set to False in all targets.
30234 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30235 if it is supported by the target.
30236 (Make_Task_Create_Call): Pass the stack address if it has been
30237 previously created. Otherwise pass a Null_Address.
30239 * snames.adb: Add _stack.
30241 * snames.ads: Add Name_uStack. Required to allow the expander to
30242 statically allocated task stacks.
30244 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30245 Stack_Address argument.
30246 Check that its value is equal to Null_Address because this target does
30247 not support the static stack allocation.
30249 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30251 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30254 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30256 * exp_dist.adb: Split declaration of asynchronous flag out of
30257 Add_RACW_Read_Attribute.
30258 Minor reformatting for better alignment with PolyORB version.
30259 Store the entity for the asynchronous flag of an RACW, rather than the
30260 expression, in the asynchronous flags table. This will allow this flag
30261 to be used in other subprograms beside Add_RACW_Read_Attribute.
30263 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30265 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30269 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30270 sockets constant MSG_NOSIGNAL (Linux-specific).
30271 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30272 all Send operations.
30273 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30274 from trigerring SIGPIPE.
30275 Rename components to avoid clash with Ada 2005 possible reserved
30277 (Check_Selector): When the select system call returns with an error
30278 condition, propagate Socket_Error to the caller.
30280 2004-10-01 Jan Hubicka <jh@suse.cz>
30282 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

30292 Minor reformatting.
30294 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30295 right way of doing things after all.

30297 unless there is an address clause present.
30299 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30301 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30302 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30303 ensures proper handling of types with rep clauses, which might have
30304 their TYPE_SIZE set already.
30306 2004-09-21 Robert Dewar <dewar@gnat.com>
30308 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30309 packed array types in both little- and big-endian cases. This change
30310 ensures that we no longer count on the unused bits being initialized
30311 for such types (and in particular ensures that equality testing will
30312 only read the relevant bits).
30313 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30314 These changes mean that we no longer need to initialize small packed
30316 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30317 optimization to an LJM field as to its parent field.
30319 * ada-tree.h, trans.c, utils.c, utils2.c:

30322 2004-09-20 Jan Hubicka <jh@suse.cz>
30324 * utils.c (gnat_finalize): Remove.
30325 (end_subprog_body): Directly call cgraph_finalize_function;
30326 do not lower the nested functions.
30328 2004-09-20 Robert Dewar <dewar@gnat.com>
30331 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30332 if an address clause is present, since that means that the Import

30361 an existing directory.
30362 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30363 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30364 Convert the result to File_Size.
30366 * prj.ads: (Project_Error): New exception
30368 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30369 Prj.Com, not from Osint.
30370 (Attrs, Package_Attributes): Tables moved to private part of spec
30371 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30373 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30374 Prj.Project_Error after call to Fail.
30375 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30376 Fail. Check that package name is not already in use.
30378 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30379 used by tools, not only by the project manager, and to indicate that
30380 exception Prj.Prj_Error may be raised in case of problem.
30381 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30383 (Attrs, Package_Attributes): Table instantiations moved from the body to
30384 the private part to be accessible from Prj.Attr.PM body.
30386 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30387 from new package Prj.Attr.PM.
30388 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30391 * Makefile.in: Add prj-attr-pm.o to gnatmake object list

30439 pragmas recognized by GNAT.
30441 * gnat_rm.texi: Document pragma Detect_Blocking.
30443 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
30444 raise Program_Error if called from a protected operation.
30446 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30447 the protected action nesting level.
30448 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30449 protected action nesting level.
30450 (Unlock): When pragma Detect_Blocking is active decrease the protected
30451 action nesting level.
30453 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30454 Protected_Action_Nesting.
30456 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30457 Common_ATCB record. It contains the dynamic level of protected action
30458 nesting for each task. It is needed for checking whether potentially
30459 blocking operations are called from protected operations.
30460 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30461 Detect_Blocking is active or not in the partition.
30463 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

30495 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30496 insertion of the statement raising Program_Error. The run time
30497 contains the required machinery for handling that.
30499 * sem_util.ads: Change comment associated to procedure
30500 Check_Potentially_Blocking_Operation.
30501 This procedure does not insert a call for raising the exception because
30502 that is currently done by the run time.
30504 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30506 * init.c: Add the global variable __gl_detect_blocking that indicates
30507 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30508 making the pragma available at run time.
30509 (__gnat_set_globals): Pass and update the detect_blocking parameter.
30511 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
30512 pragma Detect_Blocking is active.
30514 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30516 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30517 DB is found in the ali file. Any unit compiled with pragma
30518 Detect_Blocking active forces its effect in the whole partition.
30520 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30521 Detect_Blocking is active and delay is called from a protected
30524 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30525 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30526 Detect_Blocking is active (0 otherwise).
30527 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30528 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
30531 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
30533 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30534 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30537 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30538 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30539 Update API in placeholder implemetation of s-parint to reflect changes
30540 in distribution runtime library.
30542 * sem_ch3.adb (Expand_Derived_Record): Rename to
30543 Expand_Record_Extension.
30545 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30546 primitive operations of potentially distributed object types that have
30547 non-controlling anonymous access formals.
30549 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30551 New implementation of expansion for remote access-to-subprogram types,
30552 based on the RACW infrastructure.
30553 This version of sem_dist is compatible with PolyORB/DSA as well as
30556 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30557 Asynchrronous that applies to a remote access-to-subprogram type, mark
30558 the underlying RACW type as asynchronous.
30560 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30561 __gnat_using_gnu_linker to 1.
30563 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30564 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
30565 GNAT.Perfect_Hash_Generators, and remove the empty

30570 * exp_ch3.adb (Expand_Derived_Record): Rename to
30571 Expand_Record_Extension.
30572 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30573 a component declaration must remain attached at that point in the
30574 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30575 It is therefore necessary to take a copy of the expression when building
30576 the corresponding assignment statement in the init proc.
30577 As a side effect, in the case of a derived record type, we now see the
30578 original expression, without any rewriting that could have occurred
30579 during expansion of the ancestor type's init proc, and we do not need
30580 to go back to Original_Node.
30582 * exp_ch3.ads (Expand_Derived_Record): Rename to
30583 Expand_Record_Extension.
30585 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

30588 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
30589 New subprograms. Used to create a proxy tagged object for a remote
30590 subprogram. The proxy object is used as the designated object
30591 for RAS values on the same partition (unless All_Calls_Remote applies).
30592 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30593 System.Partition_Interface.Get_Unique_Remote_Pointer.
30594 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30595 Renamed from Add_RAS_*_Attribute.
30596 (Add_Receiving_Stubs_To_Declarations): Generate a table of local

30599 based on the RACW infrastructure.
30601 * exp_dist.ads (Copy_Specification): Update comment to note that this
30602 function can copy the specification from either a subprogram
30603 specification or an access-to-subprogram type definition.

30607 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30608 in an instance, between an explicit subprogram an one inherited from a
30609 type derived from an actual.
30611 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30612 add a polling call if the subprogram is to be inlined by the back-end,
30613 to avoid repeated calls with multiple inlinings.
30615 * checks.adb (Apply_Alignment_Check): If the expression in the address
30616 clause is a call whose name is not a static entity (e.g. a dispatching
30617 call), treat as dynamic.

30621 * g-trasym.ads: Minor reformatting
30623 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

30632 2004-09-09 Pascal Obry <obry@gnat.com>
30634 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30635 enable map file generation. Add the right option to generate the map
30636 file if Map_File is set to True.
30638 * gnatdll.adb (Gen_Map_File): New variable.
30639 (Syntax): Add info about new -m (Map_File) option.

30667 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
30668 of variable length temporaries for function return now that the
30669 back-end and gigi support it.

30746 consistent treatment of entity references contained within the
30747 enclosed procedure call.
30749 2004-09-01 Vincent Celier <celier@gnat.com>

30783 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
30784 target names rewrite to fix regressions with recent version of

30838 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
30839 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared

30862 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
30863 for a global aliased object with a variable size and an unconstrained
30864 nominal subtype, pretend there is no initializer if the one we have is
30865 incomplete, and avoid referencing an inexistant component in there. The
30866 part we have will be rebuilt anyway and the reference may confuse

30890 unit, this is an attempt to inline a construct that is not available in
30891 the current restricted mode, so abort rather than trying to continue.
30893 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
30894 discriminants that rename those of the parent, recover names of
30895 original discriminants for the constraint on the full view of the

30926 returning C.int, to avoid using a derived boolean type.
30928 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
30929 Duplicate_Subexpr_No_Checks in preference to direct use of

30957 ignore overflows on low and high bounds of an index to also account for
30958 differences in signedness between sizetype and gnu_index_subtype.
30959 These are as legitimate as the ones caused by a lower TYPE_PRECISION

33320 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
33322 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
33323 corresponding to a private_with must be removed from visibility; it
33324 will be made visible later, just before we analyze the private part of

33328 (Install_Siblings): Make visible the private entities of private-withed
33330 (Install_Withed_Unit): Do not install the private withed unit if we

33349 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
33350 provides the functionality of the function Is_Ancestor that was
33351 previously available in sem_ch10. It has been renamed to avoid
33354 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
33356 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

35158 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35159 protected body, indicate that the entity for the generated spec comes
35160 from source, to ensure that references are properly generated for it.
35161 (Build_Body_To_Inline): Do not inline a function that returns a
35164 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
35165 apply convention to homonyms that are declared explicitly.
35167 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
35168 that renames an equality operator and the operands are overloaded,
35169 resolve them with the declared formal types, before rewriting as an
35172 2004-03-29 GNAT Script <nobody@gnat.com>
35174 * Make-lang.in: Makefile automatically updated
35176 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
35178 * memtrack.adb: Log realloc calls, which are treated as free followed
35181 2004-03-25 Vincent Celier <celier@gnat.com>
35183 * prj-makr.adb (Process_Directories): Detect when a file contains
35184 several units. Do not include such files in the config pragmas or
35185 in the naming scheme.

35193 resolve links when computing the display names.
35195 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35197 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35198 attribute reference does not denote a subtype, it can be any
35199 expression that has a classwide type, potentially after an implicit
35200 dereference. In particular, the prefix can be a view conversion for
35201 a classwide type (for which Is_Object_Reference holds), but it can
35202 also be a value conversion for an access-to-classwide type. In the
35203 latter case, there is an implicit dereference, and the original node
35204 for the prefix does not verify Is_Object_Reference.
35206 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35207 conversion of a discriminant-dependent component of a mutable object
35210 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35212 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35213 inherited, has convention C, and has unconstrained array parameters,
35214 place the corresponding warning on the derived type declaration rather
35215 than the original subprogram.
35217 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35218 indication on renaming declaration, if formal has a box and actual
35221 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35222 determine whether to generate an implicit or explicit reference to
35223 the renamed entity.
35225 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35226 subprogram renaming comes from a defaulted formal subprogram in an
35229 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35231 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35232 value expressions to ensure that calls within a component definition
35233 will be checked (since those are evaluated during the record type's
35236 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
35238 * s-tpobop.adb: Code clean up:
35239 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

35249 * decl.c (gnat_to_gnu_entity, case E_Access_Type): Pass value
35250 of No_Strict_Aliasing to build_pointer_type_for_mode.
35251 * utils.c (update_pointer_to): Walk pointer and ref chains.
35253 2004-03-22 Cyrille Comar <comar@act-europe.fr>
35255 * ali.ads: Fix Comment about Dynamic_Elab.
35257 * gnatls.adb (Output_Unit): Add output of many flags (Dynamic_Elab,
35258 Has_RACW, Is_Generic, etc.)
35259 (Output_Object, Gnatls): Take into account ALI files not attached to
35262 2004-03-22 Vincent Celier <celier@gnat.com>
35264 * gprep.adb: Change all String_Access to Name_Id
35265 (Is_ASCII_Letter): new function
35266 (Double_File_Name_Buffer): New procedure
35267 (Preprocess_Infile_Name): New procedure
35268 (Process_Files): New procedure
35269 (Gnatprep): Check if output and input are existing directories.
35270 Call Process_Files to do the real job.
35272 2004-03-22 Robert Dewar <dewar@gnat.com>
35274 * prj-env.adb, prj-nmsc.ads, prj-proc.ads,
35275 s-stache.ads, s-stache.adb: Comment updates. Minor reformatting.
35277 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
35279 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
35280 case when the source contains only comments.
35282 2004-03-22 Ed Schonberg <schonberg@gnat.com>
35284 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35285 declaration for a child subprogram body that acts as a spec, indicate
35286 that the entity in the declaration needs debugging information.
35288 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35289 full view if the subtype is created for a constrained record component;
35290 gigi has enough information to construct the record, and there is no
35291 place in the tree for the declaration.
35293 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35294 serial number for the dummy body that is built for analysis, to avoid
35295 inconsistencies in the generation of internal names when compiling
35298 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35300 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35303 2004-03-22 GNAT Script <nobody@gnat.com>
35305 * Make-lang.in: Makefile automatically updated
35307 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35309 * decl.c (gnat_to_gnu_entity): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
35310 * trans.c (tree_transform, emit_index_check): Likewise.
35311 * utils.c (build_template): Likewise.
35312 (max_size, convert): Remove handling of WITH_RECORD_EXPR.
35313 (maybe_unconstrained_array, unchecked_convert): Likewise.
35314 * utils2.c (gnat_truthvalue_conversion, build_binary_op): Likewise.
35315 (build_unary_op): Likewise.
35316 (compare_arrays, build_allocator): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.

35322 2004-03-20 Joseph S. Myers <jsm@polyomino.org.uk>
35325 * gnat_ug.texi: Add info directory category and entry.
35326 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
35327 gnat_ug_wnt.texi: Regenerate.
35329 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
35331 * ada-tree.h: Update copyright notice.
35332 Minor reformatting.
35334 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35336 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35337 as regular exception objects and not as mere integers representing the
35338 condition code. The latter approach required some dynamics to mask off
35339 severity bits, which did not fit well into the GCC table based model.
35340 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35341 exception data objects. We don't it and it would conflict with the other
35342 external symbol we have to generate for such exceptions.
35344 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35345 the special code for VMS exceptions, since these are now represented
35346 as regular exceptions objects.
35348 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35350 * decl.c (debug_no_type_hash): Remove.

35352 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
35354 2004-03-19 Laurent Guerby <laurent@guerby.net>
35356 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35357 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35359 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35361 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35362 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35363 (TYPE_RM_SIZE_INT): Directly use type.values.
35364 (TREE_LOOP_ID): Clean up check.
35365 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35366 TYPE_VALUES, not TYPE_FIELDS.
35367 * trans.c (convert_with_check): Delay access of bounds of basetype
35368 until sure is numeric.
35370 2004-03-18 Arnaud Charlet <charlet@act-europe.fr>
35372 * 5atpopsp.adb: Remove RTEMS from list of platforms using this file.
35375 * 5ataprop.adb, 5ftaprop.adb, 5htaprop.adb, 5itaprop.adb, 5staprop.adb,
35376 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
35377 Specific.Set instead of direct call to e.g pthread_setspecific.
35379 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35381 * adaint.c: Update comments.
35383 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35384 GNATLIB_SHARED for FreeBSD.
35386 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35388 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35389 When needed (stack checking) the stack size is retrieved
35390 from the VxWorks kernel.
35392 * Makefile.in: Flag -nostdinc is required when building the run time
35393 for avoiding looking for files in the base compiler.
35394 Add the VxWorks specific version of the package body for
35395 System.Stack_checking.Operations (5zstchop.adb).
35397 * Make-lang.in: Add the object file for
35398 System.Stack_Checking.Operations.
35400 * Makefile.rtl: Add object file for the package
35401 System.Stack_Checking.Operations.
35403 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
35405 * s-stache.ads, s-stache.adb: Move the operations related to stack
35406 checking from this package to package System.Stack_Checking.Operations.
35407 This way, stack checking operations are only linked in the final
35408 executable when using the -fstack-check flag.
35410 2004-03-18 Doug Rupp <rupp@gnat.com>
35412 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
35415 * 5qsystem.ads, 5xcrtl.ads: New files.

35422 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35423 the procedures Add_To_Path_File.
35424 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35425 making sure that each directory is present only once and, for object
35426 dirs, when a directory already present is added, the duplicate is
35427 removed and the directory is always put as the last in the table.
35428 Write the path files at the end of these accumulations.
35430 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35431 Files_Htable for all sources.
35433 * prj-proc.adb (Process): Remove restrictions between not directly
35434 related extending projects.

35442 parameter Trusted_Mode.
35444 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35446 * scn.adb (Determine_License): Take into account a degenerated case
35447 when the source contains only comments.
35449 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35451 * sem_warn.adb (Check_References): For a warning on a selected
35452 component that does not come from source, locate an uninitialized
35453 component of the record type to produce a more precise error message.
35455 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35457 * 3zsoccon.ads: Fix multicast options.
35459 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35462 2004-03-15 Robert Dewar <dewar@gnat.com>
35464 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
35465 pragma used for a private type.
35467 * lib-xref.adb (Generate_Reference): Do not generate warning if
35468 reference is in a different unit from the pragma Unreferenced.
35470 * 5vtpopde.adb: Minor reformatting
35471 Fix casing of To_Task_ID
35473 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35474 flag if we have an unchecked conversion to an access type in the same
35477 2004-03-15 Geert Bosch <bosch@gnat.com>
35479 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35480 imaginary parts, use Double precision throughout.
35482 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35483 we want to be able to compile run-time with -gnata for testing, but
35484 this may also be instantiated in user code that is compiled with -gnata.
35486 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35488 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35489 codes. Having a separate type for this is useful to enforce consistency
35490 throughout the various run-time units.
35491 (Exception_Data): Use Exception_Code for Import_Code.
35493 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
35494 Natural and Integer in various places.

35496 with the severity bits masked off.
35497 (Register_VMS_Exception): Handle the additional exception data pointer
35500 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
35501 component, now reflected by an exported accessor.
35502 (is_handled_by): New routine to compute whether the propagated
35503 occurrence matches some handler choice specification. Extracted out of
35504 get_action_description_for, and expanded to take care of the VMS
35506 (get_action_description_for): Use is_handled_by instead of an explicit
35507 complex condition to decide if the current choice at hand catches the
35508 propagated occurrence.
35510 * raise.h (Exception_Code): New type for C.
35512 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35513 System.Standard_Library.Exception_Code, to allow references from the
35514 pragma import/export expander.
35516 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35517 New accessors to allow easy access to GNAT exception data
35519 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35520 redundant Handled_By_Others component, helper for the personality
35521 routine which will now be able to call the appropriate exception data
35524 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35525 component of Standard_Exception_Type to be the closest possible to
35526 Exception_Code in System.Standard_Library, that we cannot get at this
35527 point. Expand a ??? comment to notify that this type node should
35528 probably be rewritten later on.
35530 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35531 registration call to include a pointer to the exception object in the
35534 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35535 instead of int and explicit bitmasks.
35537 2004-03-15 Vincent Celier <celier@gnat.com>
35539 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35540 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35542 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35543 longer needed now that it is in the spec of
35544 System.Tasking.Task_Attributes.
35546 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35548 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35550 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35552 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35553 taken care of in Scan_Make_Arg.
35554 (Scan_Make_Arg): Add the executable suffix only if the argument
35555 following -o, in canonical case, does not end with the executable
35556 suffix. When in verbose mode and executable file name does not end
35557 with executable suffix, output the executable name, in canonical case.
35559 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35560 to avoid warnings when instantiating Ada.Task_Attributes.
35563 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35564 in the correct order.
35566 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
35567 redirect standard output and error to a file for the invocation of the
35568 compiler, then read the file.
35570 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
35571 directory, instead of the Value.
35572 (Find_Source_Dirs): Remove useless code & comments.
35574 2004-03-15 Ed Schonberg <schonberg@gnat.com>
35576 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35577 tagged type is inherited, and the parent operation is not frozen yet,
35578 force generation of a freeze node for the inherited operation, so the
35579 corresponding dispatch entry is properly initialized.
35580 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35581 when looking for user-defined equality operation.
35583 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35584 boolean when locating primitive equality of tagged component.
35586 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
35587 bit-aligned field and the right-hand side a string literal, introduce
35588 a temporary before expanding assignment into a loop.
35590 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35591 priority in full, to ensure that any expanded subepxressions of it are
35592 elaborated in the scope of the init_proc.
35594 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
35595 after object declaration, skipping over code that may have been
35596 generated for validity checks.
35598 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
35599 discriminants, ignore the known discriminants of its full view, if
35600 any, to check legality.
35602 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
35603 component if type has unknown discriminants.
35604 (Analyze_Private_Extension_Declaration): Discriminant constraint is
35605 null if type has unknown discriminants.
35607 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
35608 for end label when present.
35610 * s-fileio.adb (Open): When called with a C_Stream, use given name for
35611 temporary file, rather than an empty string.
35613 2004-03-15 Ed Falis <falis@gnat.com>
35615 * s-thread.adb: Removed, no longer used.
35617 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35619 * decl.c (target.h): Now include.
35620 (gnat_to_gnu_entity, case E_Access_Type): Use mode derived from ESIZE

35635 * 5ztpopsp.adb, 56tpopsp.adb: Fix spelling of Task_ID.
35637 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
35638 Insert_Dereference_Action when rewriting an implicit dereference into
35639 an explicit one, this will be taken care of during expansion of the
35640 explicit dereference.
35641 (Expand_N_Slice): Same. Always do the rewriting, even for the case
35642 of non-packed slices, since the dereference action generated by
35643 expansion of the explicit dereference is needed in any case.
35644 (Expand_N_Selected_Component): When rewriting an implicit dereference,
35645 analyze and resolve the rewritten explicit dereference so it is seen
35647 (Insert_Dereference_Action): This procedure is now called only for the
35648 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
35649 dereferences that do not come from source (including explicit
35650 dereferences resulting from rewriting implicit ones), but do not
35651 recursively insert a check for the dereference nodes contained within
35653 (Insert_Dereference_Action): Clarify and correct comment.
35655 2004-03-08 Paolo Bonzini <bonzini@gnu.org>

36530 checks for bitfield creation are triggered.
36531 (finish_record_type): During last pass over the fields, clear
36532 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

36872 2004-01-12 Ed Schonberg <schonberg@gnat.com>
36874 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
36875 generated to rename a generic actual, go to the actual itself, the

36991 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
36992 N_String_Literal node always references an E_String_Literal_Subtype
36993 entity. This may not be true in the future.
36994 (Possible_Bit_Aligned_Component): Move processing of
36995 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
36997 * exp_ch6.adb (Expand_Thread_Body): Pick up

36999 by possible -Dnnn binder parameter.
37001 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37002 (Type_May_Have_Bit_Aligned_Components): New function.

37042 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37043 ineffective elaborate all pragmas on non-visible packages (this
37044 happened when a renamed subprogram was called). Now the elaborate all
37045 always goes on the package containing the renaming rather than the one
37046 containing the renamed subprogram.
37048 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37049 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37074 * make.adb (Gnatmake): Special process for files to compile/check when
37075 -B is specified. Fail when there are only foreign mains in attribute
37076 Main of the project file and -B is not specified. Do not skip bind/link

37108 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37110 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37111 all attributes, including read-only attribute.

37116 library naming scheme.

37147 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37148 protected objects when allocator has a subtype indication, not a

37150 checked when limited aggregates are implemented.

37153 pure, emit warning.

37296 * sem_ch3.adb: Minor reformatting
37299 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
37300 Minor reformatting throughout
37302 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37304 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37305 bounds of a loop, create a separate block in order to generate proper
37306 cleanup actions to prevent memory leaks.
37308 * sem_res.adb (Resolve_Call): After a call to
37309 Establish_Transient_Scope, the call may be rewritten and relocated, in
37310 which case no further processing is needed.
37312 * sem_util.adb: (Wrong_Type): Refine previous fix.
37313 Fixes ACATS regressions.
37316 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always

37325 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37328 2003-12-08 Robert Dewar <dewar@gnat.com>
37330 * 7sintman.adb: Minor reformatting
37332 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37333 standard linker options to get standard libraries linked. We now plan
37334 to provide dummy versions of these libraries to match the appropriate
37335 configurable run-time (e.g. if a library is not needed at all, provide
37336 a dummy empty library).
37338 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37339 options (-L parameters and standard libraries). What we plan to do is
37340 to provide dummy libraries where the libraries are not required.
37342 * gnatbind.adb: Minor comment improvement
37344 2003-12-08 Javier Miranda <miranda@gnat.com>
37346 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37347 aggregate in the parent. Otherwise constants with limited aggregates

37355 (Has_Default_Init_Comps): Improve implementation to recursively check
37356 all the present expressions.
37358 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37359 to indicate that the initialization call corresponds to a
37360 default-initialized component of an aggregate.
37361 In case of default initialized aggregate with tasks this parameter is
37362 used to generate a null string (this is just a workaround that must be
37363 improved later). In case of discriminants, this parameter is used to
37364 generate a selected component node that gives access to the discriminant
37367 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37368 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37369 allocated aggregates with default-initialized components.

37414 Process nodes N_Comment.
37416 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37417 without comments and there are some comments, set the flag
37418 Unkept_Comments to True.
37419 (Scan): If there are comments, set the flag Unkept_Comments to True and
37420 clear the comments.
37421 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
37422 (Next_End_Nodes: New table

37450 Comment_Id and set Token to Tok_Comment when scanning a comment.
37451 (Set_Comment_As_Token): New procedure
37453 * sinput-p.adb: Update Copyright notice
37454 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
37455 that no longer exists.
37457 2003-12-08 Javier Miranda <miranda@gnat.com>
37459 * sem_aggr.adb: Add dependence on Exp_Tss package
37460 Correct typo in comment
37461 (Resolve_Aggregate): In case of array aggregates set the estimated
37462 type of the aggregate before calling resolve. This is needed to know
37463 the name of the corresponding IP in case of limited array aggregates.
37464 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37465 in case of default initialized array components.
37467 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

37485 2003-12-08 Arnaud Charlet <charlet@act-europe.fr>
37487 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
37488 they are automatically generated by Make-lang.in and cause nothing but
37489 maintenance troubles.
37491 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
37493 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

37507 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
37508 to ensure that the kernel fills in the interrupted context structure
37509 before calling a signal handler, which is necessary to be able to
37510 unwind past it. Update the copyright notice.
37512 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37514 * a-elchha.ads: New file.
37516 * a-elchha.adb: New default last chance handler. Contents taken from
37517 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.
37519 * a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine
37520 is moved to a-elchha.adb to provide a target-independent default last

37599 included in HIE_NONE_TARGET_PAIRS.
37601 2003-12-03 Ed Schonberg <schonberg@gnat.com>
37604 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
37605 is legal in an instance, because legality is cheched in the template.
37608 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
37609 appplied to an unchecked conversion of a formal parameter.
37612 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

37626 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
37627 so that the debugger can reliably access the value of the parameter,

37762 between signals and interrupts.
37763 Add to Unblocked_Signal_Mask the set of signals that are in
37767 Adding a check to see whether the Interrupt_ID we want to unmask is in
37768 the range of Keep_Unmasked (in procedure Interrupt_Self_Process). The
37769 reason is that the index type of the Keep_Unmasked array is not always
37770 Interrupt_ID; it may be a subtype of Interrupt_ID.
37772 2003-11-24 Gary Dismukes <dismukes@gnat.com>
37775 (Remove_Side_Effects): Condition constantness of object created for a

37817 2003-11-24 Sergey Rybin <rybin@act-europe.fr>
37819 * opt.adb (Tree_Write): Gnat_Version_String is now a function, so we
37820 can not use it as before (that is, as a variable) when dumping it into
37821 the tree file. Add a local variable to store the result of this
37822 function and to be used as the string to be written into the tree.
37824 * scn.adb (Initialize_Scanner): Add comments explaining the recent

38434 Adjust error message when a virtual extending project has the same
38435 object directory as an project being extended.
38436 (Recursive_Process): If name starts with the virtual prefix, set Virtual
38437 to True in the project data.

38468 N_Expanded_Names that constitute the name of a child unit, do not
38469 attempt to go further than Standard_Standard in the chain of scopes.

38968 Remove the test against being in No_Run_Time_Mode before generating a
38969 call to Register_Tag. It is redundant with the test against the

40531 xtreeprs.adb: Correct statements in comments about maintainership
40534 2002-09-23 Zack Weinberg <zack@codesourcery.com>
40536 * Make-lang.in (EXTRA_GNATBIND_OBJS): Add version.o.
40537 * Makefile.in (TOOLS_LIBS): Add ../../version.o.
40538 * gnatvsn.ads: Gnat_Version_String is now a function.
40539 * gnatvsn.adb: New file. When asked for Gnat_Version_String,
40540 copy the C version_string into a String and return it.
40541 * gnatcmd.adb, gnatkr.adb, gnatlbr.adb, gnatlink.adb,
40542 gnatls.adb,gnatmake.adb, gnatprep.adb, gnatpsta.adb:
40543 Remove pragma Ident (Gnat_Version_String). If this was the
40544 sole use of package Gnatvsn, remove the with statement too.
40545 * gnat1drv.adb: Tweak -gnatv output.
40547 2002-09-17 Richard Henderson <rth@redhat.com>
40549 * trans.c (tree_transform): Use real_ldexp not REAL_VALUE_LDEXP.
40550 * config/dsp16xx/dsp16xx.md (fixuns_trunchfhi2): Use real_2expN.
40551 * config/mips/mips.md (fixuns_truncdfsi2): Likewise.
40552 (fixuns_truncdfdi2, fixuns_truncsfsi2, fixuns_truncsfdi2): Likewise.
40553 * config/m68k/m68k.c (floating_exact_log2): Use real_exponent
40554 and real_2expN instead of a loop.

40582 function call could reallocate the table which was being indexed
40583 using its result). Fixes ada/4851. [RESURRECTED]
40585 2002-07-01 Roger Sayle <roger@eyesopen.com>

41197 function call could reallocate the table which was being indexed
41198 using its result). Fixes ada/4851.

41529 containing the name of the Ada Main Program. This string is mainly
41530 intended for the debugger.

41565 2001-12-17 Laurent Pautet <pautet@gnat.com>
41568 Fix comment of Shutdown_Socket and Close_Socket. These functions
41569 should not fail silently because if they are called twice, this
41570 probably means that there is a race condition in the user program.
41571 Anyway, this behaviour is consistent with the rest of this unit.
41572 When an error occurs, an exception is raised with the error message
41573 as exception message.

41725 (Associated_Node): Documentation explicitly mentions attribute
41726 reference nodes, since this field is used in such nodes.

42907 instead of the previous simple checksum algorithm.
42908 (Time_Stamp_Mismatch): use CRC_Match for comparison.
42909 (Set_Source_Table): idem.
42912 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
42913 instead of simple checksum.
42914 (CRC_Match): new function.
42915 (CRC_Error): new constant.
42917 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
42918 a CRC now and not a simple checksum. A CRC uses lower-case hex
42919 letters, fixes ambiguity in parsing.
42921 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
42922 is what this variable will store.
42924 * bcheck.adb: Change reference to chechsum in comments by CRC.
42925 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
42926 rename All_Checksum_Match to All_CRC_Match. Change due to API
42927 renaming since now GNAT does not use a simple checksum but a
42928 CRC using GNAT.CRC32.
42930 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
42931 now and not anymore a simple checksum.

42970 * types.adb (Hex): Use lowercase for the letter part.
42972 * types.ads (Get_Hex_String): Returns the hexadecimal representation
42973 for a word. This is currently used only for CRC. In previous version,
42974 the checksum was using a representation with all letter being
42975 upper-case. With the new implementation (using CRC) we do not remove
42976 the 32th bit of the CRC, so we can have an upper-case starting letter
42977 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
42978 It is ambigous since the CRC was optional and could be followed by
42979 options like EB, EE. So now this routines uses lower-case letter for
42980 the hexadecimal representation. Strange enough only lower case letters
42981 where checked in Scan_ALI (even if this was not a possible case).
42983 * gnatvsn.ads (Library_Version): changed to 3.15a.
42985 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
42988 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version

42992 Add 2001 to copyright notice
42993 (Accumulate_Checksum): Modify to use System.CRC32.
42995 * ali-util.ads: Redo changes of previous revision to continue to use
42996 the word Checksum. Add 2001 to copyright notice.

43001 * ali.ads: Undo previous change not needed.
43003 * bcheck.adb: Undo most of previous change, not needed.
43004 But do use Checksums_Match for checksum comparison.
