1648 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1649 Orig_Prev to Prev in the case where the actual is N_Function_Call or

3844 (Build_Discriminated_Subtype): Do not inherit representation clauses
3845 from parent type if subtype already carries them, because they are

3888 Entity and Etype to that interpretation, otherwise Entity and Etype may
3889 still refer to an interpretation that was ignored by Add_One_Interp,
3890 in which case would end up with being marked as not overloaded but with

7906 (Resolve_Actuals): If the actual is an entity name, generate a
7907 reference before the actual is resolved and expanded, to prevent
7908 spurious warnings on formals of enclosing protected operations.
7909 (Analyze_Overloaded_Selected_Component): If type of prefix if
7910 class-wide, use visible components of base type.

8016 clauses for inherited components of a type extension.
8017 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
8018 an overloadable item if it is a pragma that can apply to multiple
8019 overloadable entities (e.g. Inline) because a pragma cannot be on
8020 more than one chain at a time.

8150 subprogram body that acts as its own spec may not have a non-private
8151 WITH clause on a private sibling.
8152 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8153 child unit is a renaming, create an implicit with_clause on that
8154 parent, and not on the unit it renames, to prevent visibility errors

8258 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8259 Timed_Entry_Call): Analyze the triggering statement as the first step of
8260 the processing. If this is a dispatching select, postpone the analysis
8261 of all select statements until the Expander transforms the select. This

8263 replicated some of the select statements. In case the Expander is
8264 disabled, perform regular analysis.
8265 (Check_Triggering_Statement): New routine.
8266 (Analyze_Requeue): Exclude any interpretations that are not entries when
8267 checking overloaded names in a requeue. Also test type conformance for

8862 Add support for parsing multiple array index types info, or
8863 multiple inherited interfaces info. This information cannot be stored
8864 in Xref_Entity_Record, which only supports a single instance of Tref_*,

8883 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
8884 that handles use of 'Access and 'Unchecked_Access applied to
8885 actuals covering interface types. Such code is now
8886 centralized in Expand_N_Attribute_Reference.
8888 2007-10-15 Ed Schonberg <schonberg@adacore.com>
8890 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
8891 of tagged types whose ultimate ancestor is a CPP type.

8930 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
8931 used by VxWorks targets to have access to task-specific data and be
8932 able to extract the stack boundaries for stack checking.
8933 Use system-vms-ia64.ads on ivms.
8935 * Make-lang.in: Update dependencies.
8937 * sysdep.c (__gnat_get_stack_info): Move to a standalone file
8940 2007-10-15 Vincent Celier <celier@adacore.com>

8974 2007-10-15 Gary Dismukes <dismukes@adacore.com>
8976 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
8977 association for an access component, add an association with null as
8978 the expression. Remove testing for array subtypes and the setting in
8979 that case of Ctyp to the array component type, which prevented proper
8980 inclusion of an association for null-initialized arrays. Collapse
8981 condition that tests for array subtypes into just a test of
8982 Is_Partially_Initialized_Type (which already covers arrays anyway).
8984 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
8986 * sem_ch12.adb: Minor code reformatting.
8987 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to

8994 flag of derived concurrent types, taking into account the flag setting
8995 on the parent subtype and any new set of discriminants.
8997 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
8999 * sem_ch4.adb: Minor code and comment reformatting.
9000 (Analyze_Allocator): When the designated type of an unconstrained
9001 allocator is a record with unknown discriminants or an array with
9002 unknown range bounds, emit a detailed error message depending on the
9003 compilation mode and whether the designated type is limited.

9128 Mapped location support
9129 * back_end.adb (Call_Back_End): Pass information about source
9130 files instead of units to gigi.
9131 * gigi.h (struct File_Info_Type): New.
9132 (gigi): Rename and change type of number_units parameter, change
9133 type of file_info_ptr parameter.
9134 * trans.c (number_files): New global variable.
9135 (gigi): Rename and change type of number_units parameter, change
9136 type of file_info_ptr parameter.
9137 If mapped location support is enabled, create the isomorphic mapping
9138 between source files and line maps.
9139 (Sloc_to_locus): If mapped location support is enabled, translate
9140 source location into mapped location.
9141 (annotate_with_node): Rename into set_expr_location_from_node.

9167 * a-calend-vms.adb, a-calend.adb:
9168 Add a section on leap seconds control along with two entities used to
9169 enable and disable leap seconds support. The array Leap_Second_Times is
9170 now constant and contains hard time values pre-generated. Remove
9171 all elaboration code used to populate the table of leap seconds.
9174 Add entity Leap_Seconds_Support to the list of global run-time variables
9175 along with a comment on its usage and values.
9176 (Gen_Adainit_Ada): Add code to generate the declaration and import of
9177 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
9178 or one (enabled) depending on the presence of binder switch "-y".
9179 (Gen_Adainit_C): Add code to generate the declaration of external int
9180 __gl_leap_seconds_support. Set is value to zero (disabled) or one

9191 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
9193 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
9195 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
9196 function which can be called by the debugger to interrupt the tasks of
9197 an Ada application asynchronously, as needed on VxWorks.
9198 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
9200 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
9201 renamed from Stop_All_Tasks. Update comments.

9217 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
9219 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9222 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9224 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9227 * sem_dist.ads: Minor comment fix

9231 2007-09-26 Javier Miranda <miranda@adacore.com>
9232 Eric Botcazou <ebotcazou@adacore.com>
9235 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9236 indirection added to the HT_Link component of the TSD. This is required
9237 to statically allocate the TSD.
9240 Minor reordering of the declarations in the private part. Required to
9241 add a level of indirection to the contents of the TSD component HT_Link.
9242 This is required to statically allocate the TSD.
9244 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9245 Is_Statically_Allocated set from constant objects.
9246 Do not make exported constants created by the compiler volatile.
9247 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9250 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9251 before returning them.
9253 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9254 public part of the package.
9255 (Make_DT): Move HT_Link component out of the TSD record. For this
9256 purpose Make_DT now declares a separate object that stores the
9257 HT_Link value, and initializes the TSD component with the address
9258 of this new object. The addition of this level of indirection is
9259 required to statically allocate the TSD because the TSD cannot
9260 have variable components.
9261 (Expand_Interface_Conversion): Improve the expanded code.
9262 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9264 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9265 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9266 if we are building static dispatch tables then we must not generate
9267 extra code to register the primitive because the dispatch table will
9268 be built at the end of the library package; otherwise we notify that
9269 we cannot build the static dispatch table.
9271 2007-09-26 Robert Dewar <dewar@adacore.com>
9273 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9288 for thunks associated with interface types.
9290 * einfo.ads: Improve documentatation of Is_Internal
9291 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9292 associated with interface types.
9293 Extensive comment fixes regarding flags that appear in all entities. The
9294 documentation is now consistent for all such flags (there were a number
9295 of errors in the documentation in this regard).
9297 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9299 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9300 of these procedures are passed a function call that already has
9301 build-in-place actuals (testing new flag
9302 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9303 the case where processing continues.
9304 (Expand_Call): If the call is generated from a thunk body then we
9305 propagate the extra actuals associated with the accessibility
9306 level of the access type actuals.
9308 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9309 of each extra formal of a protected operation to reference the
9310 corresponding extra formal of the subprogram denoted by the
9311 operation's Protected_Body_Subprogram.
9313 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9314 N_Function_Call nodes.
9316 2007-09-26 Robert Dewar <dewar@adacore.com>
9318 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9320 * debug.adb: Add d.s flag.
9322 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9324 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9325 debug variable so that it won't be initialized when pragma
9326 Initialize_Scalars is in effect.
9328 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9330 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9331 initialization of a full view. This is moved to
9332 Analyze_Package_Specification.
9334 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9335 preelaborable initialization of a full view in entity loop.
9336 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9337 its child units are use-visible only if they are visible child units.
9339 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9340 whether an expression can be used within a type declaration that
9341 requires preelaborable init.
9342 (Check_Components): Replace inline code that does partial checking for
9343 preelaborable default expressions with call to
9344 Is_Preelaborable_Expression.
9345 (Has_Preelaborable_Initialization): In the case of a generic actual
9346 subtype, (that is, Is_Generic_Actual is True), return the result of
9347 applying Has_Preelaborable_Initialization to the generic actual's base
9350 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9352 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9353 call to Jan_1_Day _Of_Week to optimize its performance.
9354 (Is_Leap): Move the routine to the scope of Week_In_Year.
9355 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9356 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9357 avoids calling Time_Of and Split, thus making it more efficent.
9358 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9360 * g-calend.ads (Week_In_Year): Change comment to reflect new
9363 2007-09-26 Emmanuel Briot <briot@adacore.com>
9365 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9366 Command_Line): New types
9367 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9368 support for defining how switches can be grouped on a command line (as
9369 is the case for -gnatw... for GNAT), and how simple switches can be
9370 used as aliases for more complex switches (-gnatwa is same as
9372 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9373 (Start, Current_*): New subprograms
9374 Added support for parsing an array of strings in addition to the real
9376 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9377 be moved from the body to the private part of the spec.
9378 (*): All subprograms now have an extra parameter with default value to
9379 specify which parser should be used. For backward compatibility, it
9380 defaults to parsing the command line of the application. They were also
9381 modified to properly handle cases where each of the argument does not
9382 start at index 1 (which is always true for Ada.Command_Line, but not
9383 when processing any Argument_List).
9384 (Free): New subprogram
9385 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9386 Argument): New subprograms
9387 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9388 special characters like ':', '=',... are now handled in a single place,
9389 which makes the code more extensible eventually.
9390 (Getopt, Full_Switch): When the switch was returned as part of the
9391 special character '*', make sure it is prepended by the switch character
9392 ('-' in general), so that the application knows whether "foo" or "-foo"
9393 was specified on the command line.
9395 2007-09-26 Florian Villoing <villoing@adacore.com>
9397 * g-dirope.adb (Remove_Dir): In case we are removing directories
9398 recursively, make sure that if an exception is raised during the
9399 processing, the current working directory is reset to its initial
9400 value before propagating the exception.
9402 2007-09-26 Vincent Celier <celier@adacore.com>
9404 * gnatbind.adb: If there are several ALI files specified and there is
9405 a main program to bind, the first ALI is expected to contain the main
9406 subprogram and the names of the binder generated files will be derived
9407 from the first ALI file name.
9408 (Gnatbind): Fix insertion character in invocation of Error_Msg
9410 2007-09-26 Vincent Celier <celier@adacore.com>
9412 * gnatcmd.adb (Check_Files): Do not include sources that have been
9413 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9415 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9417 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9418 information about each of its index types, following the type

9791 potentially be called.
9792 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9793 body for 'Output when the type is abstract (only the creation of the
9794 body for 'Input is excluded when the type is abstract).
9795 (Stream_Operation_OK): Add an additional condition in the return
9796 statement, so that False will be returned for TTS_Stream_Input if the
9797 associated tagged type is an abstract extension. Add comments for

9800 variable, insert init proc call only after the shared variable
9801 procedures have been processed, because the IP call needs to undergo
9802 shared passive variable reference expansion, which requires these
9803 procedures to be available (and elaborated).

9819 to remove other spurious ambiguities on arithmetic operations involving
9820 literals and addresses, on systems where Address is a visible integer
9821 type, when the operator is called in functional notation.
9822 (Try_Primitive_Operation): Within an instance, a call in prefixed form
9823 is legal when the types match, even if the operation is currently

9974 that its encoded name is properly qualified.
9976 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
9977 occurring in the list of entities to qualify, and do not attempt to

10003 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10004 concatenations of string literals into a single literal, in order to
10005 avoid very deep recursion in the front end, which was causing stack
10008 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10009 string, and the right operand is a string literal (the case of "" &

10011 value of the right operand directly.
10013 * stringt.adb (Store_String_Chars): Optimize by growing the
10014 String_Chars table all at once, rather than appending characters one by
10016 (Write_String_Table_Entry): If the string to be printed is very long,
10017 just print the first few characters, followed by the length. Otherwise,
10018 doing "pn(n)" in the debugger can take an extremely long time.
10020 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10021 Store_String_Char with Store_String_Chars.

10040 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10041 flag, for effiency. It is called when analyzing arithmetic operators
10042 and also for actuals in calls that are universal_integers. The flag is
10043 set for the predefined type address, and for any type or subtype
10046 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10047 Universal_Integer, when the formal is a descendent of address and the
10048 call appears in user code.

10115 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10116 associated with Standard_Debug_Renaming_Type, to be used as the type of
10117 the special variables whose names provide debugger encodings for
10118 renaming declarations.
10120 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10121 (Set_Debug_Renaming_Link): Change to set Node25.

10131 and the entity of the renaming declaration.
10132 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10133 part of the name of a variable that has a Debug_Renaming_Link.
10135 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a

10140 Ed Schonberg <schonberg@adacore.com>
10141 Javier Miranda <miranda@adacore.com>
10143 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10144 ancestor part given by an aggregate to test for an unchecked conversion,
10145 since this can occur in some cases when the ancestor part is a function
10146 call, and we don't want to fall into the recursive call to this
10147 procedure in that case.
10149 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10150 stream attributes on limited types to account for user-specified
10151 attributes as well as whether Input (resp. Output) becomes available
10152 due to Read (resp. Write) being available for the type. Change Boolean
10153 variable to the more accurate name
10154 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10155 double-"not" predicate at beginning of return statement to more
10156 understandable form.
10158 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10159 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10160 in a block statement and use that as the first statement of the
10161 expanded return rather than incorrectly using the handled sequence as
10162 the first statement.
10164 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10165 operation, generate an explicit freeze node for it rather than
10166 generating extra formals, to ensure that gigi has the proper order of
10167 elaboration for anonymous subtypes in the signature of the subprograms.
10168 (Build_In_Place_Formal): Move assertion to beginning of loop.
10169 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

10178 * freeze.adb (Freeze_Record_Type): Extend the current management of
10179 components that are access type with an allocator as default value: add
10180 missing support to the use of qualified expressions of the
10181 allocator (which also cause freezing of the designated type!)
10182 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10183 dispatching operation, since extra formals may be needed by calls to
10184 build-in-place functions (such as stream 'Input).
10186 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10187 formals for 'Constrained and accessibility level in the case of a
10188 predefined dispatching operation.
10190 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10191 point, no need to find the parent node.
10193 2007-08-16 Javier Miranda <miranda@adacore.com>
10195 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10196 and entry barriers.
10198 2007-08-16 Javier Miranda <miranda@adacore.com>
10200 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10201 is not really required and can introduce regression with the debugger.
10202 The original problem is fixed with the patch written for checks.adb.

10216 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10217 parameter Including_Non_Switch, defaulted to True. When
10218 Including_Non_Switch is False, options that are not switches and
10219 appear as relative path are not converted to absolute paths.

10234 from the immediate ancestor of Main_Unit_Entity.
10235 (Install_Limited_Withed_Unit): Do not install the limited view of
10236 package P if P is reachable through an ancestor chain from package C
10237 and C also has a with clause for P in its body.
10238 (Has_Limited_With_Clause): New routine.
10239 (Has_With_Clause): New routine.
10241 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10243 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10244 generic for an enclosing instance is a global reference, even though
10245 its scope is the enclosing instance.

10271 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10272 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10273 the statement which is being resolved comes from a predefined library
10274 unit, all non-predefined library interpretations are skipped.
10275 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10276 but the "&" is user defined, give an error, because the folding would

10328 switch -gnatyS. Enable -gnatyS in GNAT style check mode
10330 2007-08-14 Robert Dewar <dewar@adacore.com>
10331 Ed Schonberg <schonberg@adacore.com>
10333 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10334 Suppress unmodified in-out parameter warning in some cases
10335 This patch is a also fairly significant change to the way suppressible
10336 checks are handled.
10338 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10339 needed for access to concurrent record types generated by the expander.
10340 (Generate_Range_Check): When generating a temporary to capture the
10341 value of a conversion that requires a range check, set the type of the
10342 temporary before rewriting the node, so that the type is always
10343 properly placed for back-end use.
10344 (Apply_Float_Conversion_Check): Handle case where the conversion is
10346 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10347 for a protected type in order to examine its discriminants.

10352 Thomas Quinot <quinot@adacore.com>
10354 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10355 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10356 tests optimized out.
10358 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10359 (Get_Allocator_Final_List): For the case of an anonymous access type
10360 that has a specified Associated_Final_Chain, do not go up to the
10362 (Expand_N_Type_Conversion): Test for the case of renamings of access
10363 parameters when deciding whether to apply a run-time accessibility
10365 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10366 aggregate code before allocator, and ahead of declaration for
10367 temporary, to prevent access before elaboration when the allocator is
10368 an actual for an access parameter.
10369 (Expand_N_Type_Conversion): On an access type conversion involving an
10370 access parameter, do not apply an accessibility check when the
10371 operand's original node was an attribute other than 'Access. We now
10372 create access conversions for the expansion of 'Unchecked_Access and
10373 'Unrestricted_Access in certain cases and clearly accessibility should
10374 not be checked for those.
10376 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10377 includes a type conversion of a packed component that has been expanded,
10378 recover the original expression for the object, and use this expression
10379 in the post-call assignment statement, so that the assignment is made
10380 to the object and not to a back-end temporary.
10381 (Freeze_Subprogram): In case of primitives of tagged types not defined
10382 at the library level force generation of code to register the primitive
10383 in the dispatch table. In addition some code reorganization has been
10384 done to leave the implementation clear.
10385 (Expand_Call): When expanding an inherited implicit conversion,
10386 preserve the type of the inherited function after the intrinsic
10387 operation has been expanded.
10389 * exp_ch2.ads, exp_ch2.adb
10390 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10391 of an entry formal appearing in an assignment statement does not assign
10393 (Expand_Current_Value): Instead of calling a routine to determine
10394 whether the prefix of an attribute reference should be optimized or
10395 not, prevent the optimization of such prefixes all together.
10397 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10398 component whose prefix is known to be of an access type is an implicit
10399 dereference and does not assign to the prefix.
10401 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10402 Robert Dewar <dewar@adacore.com>
10404 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10405 itype is visited, make an entry into table to link associated node and
10407 Add comments and correct harmless error in Build_NCT_Hash_Tables
10408 (Array_Aggr_Subtype): Associate each itype created for an index type to
10409 the corresponding range construct, and not to the aggregate itself. to
10410 maintain a one-to-one correspondence between itype and its associated
10411 node, to prevent errors when complex expression is copied.
10412 Fix mishandling of multiple levels of parens
10414 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10415 treatment of limited views uniform for all visible declarations in a
10416 limited_withed package.
10417 (New_Copy_Tree): If hash table is being used and itype is visited,
10418 make an entry into table to link associated node and new itype.
10419 (Resolve_Record_Aggregate): Do not add an others box association for a
10420 discriminated record component that has only discriminants, when there
10421 is a box association for the component itself.
10423 * par-ch4.adb: Fix mishandling of multiple levels of parens
10425 2007-08-14 Robert Dewar <dewar@adacore.com>
10427 * comperr.adb: Fix problem with suppressing warning messages from gigi
10429 * erroutc.ads, erroutc.adb, errout.ads,
10430 errout.adb (Write_Eol): Remove trailing spaces before writing the line
10431 (Write_Eol_Keep_Blanks): New procedure to write a line, including
10432 possible trailing spaces.
10433 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
10434 Fix problem with suppressing warning messages from back end
10435 Improve handling of deleted warnings
10438 Fix problem with suppressing warning messages from back end
10439 Handle setting of Static_Dispatch_Tables flag.
10442 Fix problem with suppressing warning messages from back end

10461 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
10462 to make treatment of limited views uniform for all visible declarations
10463 in a limited_withed package.
10464 Improve warnings for in out parameters
10465 (Set_Related_Interaface/Related_Interface): Allow the use of this
10466 attribute with constants.
10467 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10468 Warn on duplicate pragma Preelaborable_Initialialization
10470 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10471 generation of a freezing node to ensure proper management of null
10472 excluding access types in the backend.
10473 (Create_Extra_Formals): Test base type of the formal when checking for
10474 the need to add an extra accessibility-level formal. Pass the entity E
10475 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10476 originally being done in a couple of cases), to ensure that the
10477 Extra_Formals list gets set on the entity E when the first entity is
10479 (Conforming_Types): Add missing calls to Base_Type to the code that
10480 handles anonymous access types. This is required to handle the
10481 general case because Process_Formals builds internal subtype entities
10482 to handle null-excluding access types.
10483 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10484 functions that need it, even when not marked Requires_Overriding.
10485 Improve warnings for in out parameters
10486 (Analyze_Function_Return): Warn for disallowed null return
10487 Warn on return from procedure with unset out parameter
10488 Ensure consistent use of # in error messages
10489 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10490 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10491 the implicit conversion of the expression done for anonymous access
10492 types. This is required to generate the code of the null excluding
10493 check (if required).
10495 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10496 A formal parameter is never publicly referenceable outside of its body.
10497 (Check_References): For an unreferenced formal parameter in an accept
10498 statement, use the same warning circuitry as for subprogram formal
10500 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10501 Output_Unreferenced_Messages, containing the part of that routine that
10502 is now reused for entry formals as described above.
10503 (Goto_Spec_Entity): New function
10504 (Check_References): Do not give IN OUT warning for dispatching operation
10505 Improve warnings for in out parameters
10506 (Test_Ref): Check that the entity is not undefinite before calling
10507 Scope_Within, in order to avoid infinite loops.

10512 Javier Miranda <miranda@adacore.com>
10513 Gary Dismukes <dismukes@adacore.com>
10515 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10516 (Expand_N_Attribute_Reference): Further unify the handling of the
10517 three forms of access attributes, using common code now for all three
10518 cases. Add a test for the case of applying an access attribute to
10519 an explicit dereference when the context is an access-to-interface
10520 type. In that case we need to apply the conversion to the prefix
10521 of the explicit dereference rather than the prefix of the attribute.
10522 (Attribute_Version, UET_Address): Set entity as internal to ensure
10523 proper dg output of implicit importation.
10524 (Expand_Access_To_Type): Removed.
10525 (Expand_N_Attribute_Reference): Merge the code from the three cases
10526 of access attributes, since the processing is largely identical for
10527 these cases. The substantive fix here is to process the case of a
10528 type name prefix (current instance case) before handling the case
10529 of interface prefixes.

10534 Robert Dewar <dewar@adacore.com>
10536 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10537 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10538 type that is an anonymous access to controlled object, establish
10539 an associated finalization chain to avoid corrupting the global
10540 finalization list when a dynamically allocated object designated
10541 by such a component is deallocated.
10542 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10543 functions that need it, even when not marked Requires_Overriding.
10544 (Initialize_Tag): Replace call to has_discriminants by call to
10545 Is_Variable_Size_Record in the circuitry that handles the
10546 initialization of secondary tags.
10547 (Is_Variable_Size_Record): New implementation.
10548 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10549 Suppress_Initialization pragma for a derived type.
10550 (Is_Variable_Size_Record): New subprogram.
10551 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10552 initial version of this routine and also fixes problems causing
10553 incomplete initialization of the table of interfaces.
10554 (Build_Init_Procedure): Improve the generation of code to initialize the
10555 the tag components of secondary dispatch tables.
10556 (Init_Secondary_Tags): New implementation that simplifies the previous
10557 version of this routine.
10558 (Make_DT): Add parameter to indicate when type has been frozen by an
10559 object declaration, for diagnostic purposes.
10560 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10561 diagnose attemps to freeze a subprogram when some untagged type of its
10562 profile is a private type whose full view has not been analyzed yet.
10563 (Freeze_Array_Type): Generate init proc for packed array if either
10564 Initialize or Normalize_Scalars is set.
10565 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10566 constructing the new profile, copy the null_exclusion indicator for each
10567 parameter, to ensure full conformance of the new body with the spec.
10569 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10570 Create wrappers for constructor functions that need it, even when not
10571 marked Requires_Overriding.
10572 (Covers): Handle properly designated types of anonymous access types,
10573 whose non-limited views are themselves incomplete types.
10574 (Add_Entry): Use an entity to store the abstract operation which hides
10576 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10577 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10578 initialization aggregate.
10579 (Function_Interp_May_Be_Hidden): Rename to
10580 Function_Interp_Has_Abstract_Op.
10581 (Has_Compatible_Type): Remove machinery that skips interpretations if
10582 they are labeled as potentially hidden by an abstract operator.
10583 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10584 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10585 (Write_Overloads): Output the abstract operator if present.
10586 (Add_Entry): Before inserting a new entry into the interpretation table
10587 for a node, determine whether the entry will be disabled by an abstract
10589 (Binary_Op_Interp_May_Be_Hidden): New routine.
10590 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10592 (Function_Interp_May_Be_Hidden): New routine.
10593 (Has_Compatible_Type): Do not consider interpretations hidden by
10594 abstract operators when trying to determine whether two types are
10596 (Has_Hidden_Interp): New routine.
10597 (Set_May_Be_Hidden_Interp): New routine.
10598 (Write_Overloads): Write the status of flag May_Be_Hidden.

10601 Javier Miranda <miranda@adacore.com>
10603 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
10604 types declared in the declarative part of a nested package body or in
10605 the proper body of a stub.
10606 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10607 of the same dispatch table slot to renamed primitives.
10608 (Make_Select_Specific_Data_Table): Handle private types.
10609 (Tagged_Kind): Handle private types.
10610 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10611 output of implicit importation and exportation.
10612 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10613 first formal of the thunk is always associated with the controlling
10614 type. In addition perform the following code cleanup: remove formal
10615 Thunk_Alias which is no longer required, cleanup evaluation of the
10616 the controlling type, and update the documentation.
10617 Replace occurrence of Default_Prim_Op_Count by
10618 Max_Predef_Prims. Addition of compile-time check to verify
10619 that the value of Max_Predef_Prims is correct.
10620 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10621 (Make_DT): Add parameter to indicate when type has been frozen by an
10622 object declaration, for diagnostic purposes.
10623 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10624 construction of statically allocated dispatch tables.
10625 (Make_DT): In case of library-level tagged types export the declaration
10626 of the primary tag. Remove generation of tags (now done by Make_Tags).
10627 Additional modifications to handle non-static generation of dispatch
10628 tables. Take care of building tables for asynchronous interface types
10629 (Make_Tags): New subprogram that generates the entities associated with
10630 the primary and secondary tags of Typ and fills the contents of Access_
10631 Disp_Table. In case of library-level tagged types imports the forward
10632 declaration of the primary tag that will be declared later by Make_DT.
10633 (Expand_Interface_Conversion): In case of access types to interfaces
10634 replace an itype declaration by an explicit type declaration to avoid
10635 problems associated with the scope of such itype in transient blocks.
10637 2007-08-14 Robert Dewar <dewar@adacore.com>
10638 Ed Schonberg <schonberg@adacore.com>
10639 Javier Miranda <miranda@adacore.com>
10641 * exp_util.ads, exp_util.adb:
10642 This patch replaces a number of occurrences of explicit tests for N_Null
10643 with calls to Known_Null. This improves tracking of null values, since
10644 Known_Null also catches null constants, and variables currently known to
10645 be null, so we get better tracking.
10646 (Ensure_Defined): create an itype reference only in the scope of the
10648 (Side_Effect_Free): A selected component of an access type that
10649 denotes a component with a rep clause must be treated as not
10650 side-effect free, because if it is part of a linked structure its
10651 value may be affected by a renaming.
10652 (Expand_Subtype_From_Expr): For limited objects initialized with build
10653 in place function calls, do nothing; otherwise we prematurely introduce
10654 an N_Reference node in the expression initializing the object, which
10655 breaks the circuitry that detects and adds the additional arguments to
10656 the called function. Bug found working in the new patch for statically
10657 allocated dispatch tables.
10658 (Is_Library_Level_Tagged_Type): New subprogram.
10659 (Remove_Side_Effects): If the expression of an elementary type is an
10660 operator treat as a function call.
10661 (Make_Literal_Range): If the index type of the array is not integer, use
10662 attributes properly to compute the constraint on the resulting aggregate
10665 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10666 class-wide type whose base type is an incomplete private type, leave
10667 class-wide type unfrozen so that freeze nodes can be generated
10668 properly at a later point.
10669 (Freeze_Entity, array case): Handle case of pragma Pack and component
10670 size attributre clause for same array.
10672 2007-08-14 Vincent Celier <celier@adacore.com>

10725 Allow all valid declarations in configuration project files
10726 (Search_Directories): Detect subunits that are specified with an
10727 attribute Body in package Naming. Do not replace a source/unit in the
10728 same project when the order of the source dirs are known. Detect
10729 duplicate sources/units in the same project when the order of the
10730 source dirs are not known.
10731 (Check_Ada_Name): Allow all identifiers that are not reserved words
10733 Major update of the Project Manager and of the project aware tools,
10734 including gprmake, so that the same sources in the GNAT repository
10735 can be used by gprbuild.

10737 directory of non extending project to nil.
10738 Change type of path name variables to be Path_Name_Type
10739 (Locate_Directory): Make sure that on Windows '/' is converted to '\',

11298 (Set_Item): When the new item is an element of the currently allocated
11299 table passed by reference, save a copy on the stack if we're going

11319 operations in Derive_Subprograms.
11320 (Collect_Previous_Instances): new procedure within of
11321 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11322 unit being loaded, to ensure that the generation of global symbols is
11323 consistent in different compilation modes.
11324 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11325 takes progenitor types into account.
11326 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11327 traversing over the primitives of the formal and actual types to locate
11328 any abstract subprograms of the actual type that correspond to a
11329 nonabstract subprogram of the formal type's ancestor type(s), and issue
11330 an error if such is found.
11331 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11332 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11333 Remove bogus guard around calls to Inherit_Context.
11334 (Reset_Entity): If the entity is the selector of a selected component

11343 parameter to determine whether operation applies to the prefix.
11344 (Complete_Object_Operation): If actual has an access type and

11346 an access_to_constant type.
11347 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11348 type, the candidate operations are found in the scope of declaration of
11349 the type, because the type has no primitive subprograms.
11350 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11351 a private extension, only examine visible components before trying to
11352 analyze as a prefixed call.
11353 Change Entity_List to Type_To_Use, for better readability.

11366 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11367 purpose of enforcing E.2.2(8) only if it is not available at any place.
11368 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11369 when checking the legality of an extension aggregate in a preelaborable
11370 package. Treat the literal null as a valid default expression in a
11371 component declaration for a type with preelaborable initialization.
11372 A limited interface is a legal progenitor for the designated type of a
11373 remote access to class-wide type.

11386 (Find_Selected_Component, Has_Components): Handle properly non-limited
11387 views that are themselves incomplete types.
11388 Handle interfaces visible through limited-with clauses.
11389 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11390 subprogram generic actual for which we have generated a renaming.
11391 Warn when the renaming introduces a homonym of
11392 the renamed entity, and the renamed entity is directly visible.

11402 (Resolve): Skip an interpretation hidden by an abstract operator only
11403 when the type of the interpretation matches that of the context.
11404 (Resolve): When looping through all possible interpretations of a node,
11405 do not consider those that are hidden by abstract operators.
11406 (Resolve_Actuals): When verifying that an access to class-wide object
11407 is an actual for a controlling formal, ignore anonymous access to
11408 subprograms whose return type is an access to class_wide type.
11409 (Resolve_Slice): If the prefix of the slice is a selected component
11410 whose type depends on discriminants, build its actual subtype before
11411 applying range checks on the bounds of the slice.
11412 (Valid_Conversion): In an instance or inlined body, compare root types,
11413 to prevent anomalies between private and public views.

11433 extraneous layer of Any wrapping for member label.
11434 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
11435 elabration statements, register the package with the name server
11436 at the beginning, not at the end, of the elaboration statements so
11437 that they can create remote access to subprogram values that designate
11438 remote subprograms from the package.

11648 Add s-osinte-vxworks-kernel.adb to the target pairs of the
11649 kernel run-time lib for VxWorks 6, which would provide a different
11650 implementation for Task_Cont and Task_Stop than the VxWorks 5 version.

12538 2007-06-06 Vincent Celier <celier@adacore.com>
12540 * bindusg.adb: Add line for @<response file>
12541 Add lines for new switches -R and -Z
12543 * gnatbind.adb (Gnatbind): Do not include sources from the GNAT
12544 hierarchy in the list of files of the closure when -R is used
12545 (Gnatbind): Accept arguments starting with '@' to indicate response
12546 files and take the arguments from the response files.
12547 If List_Closure is set, display the referenced files

12550 Robert Dewar <dewar@adacore.com>
12551 Ed Schonberg <schonberg@adacore.com>
12553 * checks.ads, checks.adb (Apply_Address_Clause_Check): Handle case in
12554 which the address-clause is applied to in-mode actuals (allowed by
12556 (Apply_Discriminant_Check): Do not generate a check if the type is
12557 constrained by a current instance.
12558 (Activate_Division_Check): New procedure
12559 (Activate_Overflow_Check): New procedure
12560 (Activate_Range_Check): New procedure
12561 Call these new Activate procedures instead of setting flags directly
12562 (Apply_Array_Size_Check): Removed, no longer needed.
12563 Code clean up: remove obsolete code related to GCC 2.
12564 (Get_E_Length): Protect against bomb in case scope is standard
12565 (Selected_Range_Checks): If the node to be checked is a conversion to
12566 an unconstrained array type, and the expression is a slice, use the
12567 bounds of the slice to construct the required constraint checks.
12568 Improve NOT NULL error messages
12569 (Apply_Constraint_Check): If the context is a null-excluding access
12570 type, diagnose properly the literal null.
12572 2007-06-06 Pascal Obry <obry@adacore.com>
12574 * clean.adb (Clean_Archive): Use untouched casing for the archive name
12575 and the corresponding .deps file.
12576 (Clean_Interface_Copy_Directory): Use untouched casing for the library
12577 src directory. Minor code-clean-up. Use untouched casing for files
12578 read into the library src dir.
12579 (Clean_Library_Directory): Idem.
12580 (Parse_Cmd_Line): Accept new switch -aP

12585 Eric Botcazou <ebotcazou@adacore.com>
12586 Arnaud Charlet <charlet@adacore.com>
12588 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12589 applicable to types that have the With_Type flag set. Returns the
12590 non-limited view of the type, if available, otherwise the type itself.
12591 For class-wide types, there is no direct link in the tree, so we have
12592 to retrieve the class-wide type of the non-limited view of the Etype.
12593 New attributes Static_Initialization and Static_Elaboration_Desired.
12594 Remove the pragma Thread_Body, and the associated flag
12595 Is_Thread_Body in entities, and all related code.
12596 (Suppress_Value_Tracking_On_Call): New flag
12597 E_Exception has Esize and Alignment fields
12598 (Universal_Aliasing): New function.
12599 (Set_Universal_Aliasing): New procedure.
12600 (Write_Entity_Flags): Deal with Universal_Aliasing flag.
12601 (Check_Nested_Access): New procedure.
12602 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
12603 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
12604 (Related_Interface): New attribute. Present in dispatch table pointer
12605 components of records. Set to point to the entity of the corresponding
12607 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
12608 (Original_Access_Type): Remove, not needed.
12609 (Root_Type): Handle properly subtypes of class-wide-types.
12612 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12613 class-wide types visible through limited-with clauses.
12614 (Try_Primitive_Operation): When examining all primitive operations of a
12615 tagged type, do not consider subprograms labeled as hidden unless they
12616 belong to a private generic type with a tagged parent.
12617 (Try_Object_Operation): Extensive rewriting, to handle properly various
12618 overloading cases, when several ancestors may have class-wide operations
12619 that are possible candidates, and when the overloaded functions return
12620 array types and have defaulted parameters so that the call may be
12621 interpreted as an indexing.
12622 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12623 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12624 successive actuals before analyzing the call itself.
12625 (Try_Primitive_Operation): A primitive operation is compatible with the
12626 prefix if the prefix has a synchronized type and the type of the formal
12627 is its corresponding record, as can be the case when the primitive
12628 operation is declared outside of the body of the type.
12629 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12630 perform homonym traversal, looking for class-wide operation matches
12631 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12632 access parameters are now restricted to anonymous access types.
12633 (Mark_Allocator): An allocator with a discriminant association parent is
12635 (Try_One_Prefix_Interpretation): If the type of the object is
12636 incomplete, as can be happen when it is a limited view obtained through
12637 a limited_with_clause, the selected component is not part of a prefixed
12639 (Complete_Object_Operation): Diagnose properly an object that is not
12640 aliased when the corresponding controlling formal is an access
12642 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12643 ambiguous calls in prefixed notation, where two primitives differ only
12644 in that the controlling argument of one is an access parameter.
12646 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12647 whether a function that returns an unconstrained type can be inlined.
12648 (Process_Formals): Diagnose properly the illegal use of an incomplete
12649 type in the profile of an access_to_subprogram declaration.
12650 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12651 operations are attached to the corresponding record.
12652 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12653 When processing a primitive of a concurrent type which implements an
12654 interface change the type of all controlling formals to that of the
12655 corresponding record type.
12656 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12657 to determine the tagged type to which a primitive belongs.
12658 (Check_Conventions): Capture condition to ignore a primitive operation
12659 (which is shared between the loop in Check_Conventions and the one in
12660 Check_Convention) in a new local function Skip_Check.
12661 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12662 confusion with Check_Conventions' own Prim_Op local variable.
12663 (Create_Extra_Formals): Test for a tagged result type rather than a
12664 controlling result when determining whether to add a BIP_Alloc_Form
12665 formal and a BIP_Final_List formal to the function.
12666 (Check_Conformance); For parameters that are anonymous access types,
12667 subtype conformance requires that the not null and the constant
12668 indicators must match
12669 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12670 to retrieve the appropriate type when processing a concurrent type
12671 declared within a generic. Minor comment reformatting. Change invocation
12672 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12674 (Analyze_Subprogram_Body): If the return type of a function is an
12675 anonymous access to the limited view of a class-wide type, and the
12676 non-limited view of the type is available, update the type of the
12677 function so that code can be generated.
12678 (Process_Formals): In case of access-subtype itype whose designated
12679 type is also an itype (situation that happens now with access to
12680 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12681 attribute to avoid backend problems.
12682 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12683 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12684 anonymous types' designated types are same before testing
12685 Subtypes_Statically_Match.
12686 (Create_Extra_Formals): Test for a named access parameter that is a
12687 controlling formal as an additional condition for adding an
12688 accessibility level formal. This can occur in the subp type created for
12689 dispatching calls in Expand_Dispatching_Call, and allows calling
12690 Create_Extra_Formals from that procedure rather than special-casing the
12691 extra formals there.
12692 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12693 when the function has a controlling result.
12694 (Check_Returns): Add much more knowledge of the optimization of local
12695 raise statements to gotos, to retain proper warnings in this case.
12696 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12697 nodes when looking for last statement.
12699 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12700 class-wide types visible through limited with clauses.
12701 (Add_One_Interp): If the operands are anonymous access types, the
12702 predefined operator on universal_access is immediately visibles
12703 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12704 other anonymous access types.
12705 (Disambiguate): Take into account CIL convention.
12706 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12708 2007-06-06 Robert Dewar <dewar@adacore.com>
12710 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,

12712 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
12713 Fix lower bound of tables.
12716 * nlists.adb: Ditto.
12717 (Prev_Node, Next_Node): Change index type to Int so that it properly
12718 covers the range First_Node_Id - 1 up.
12720 2007-06-06 Javier Miranda <miranda@adacore.com>
12721 Ed Schonberg <schonberg@adacore.com>
12722 Bob Duff <duff@adacore.com>
12723 Hristian Kirtchev <kirtchev@adacore.com>
12725 * exp_aggr.ads, exp_aggr.adb:
12726 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12727 in extension aggregates.
12728 (Flatten): Other conditions being met, an aggregate is static if the
12729 low bound given by component associations is different from the low
12730 bound of the base index type.
12731 (Packed_Array_Aggregate_Handled): If the component type is itself a
12732 packed array or record, the front-end must expand into assignments.
12733 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12734 Init_Pr, instead of Ancestor_Is_Expression.
12735 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12736 coextension chain root, either generate a list controller or use the
12737 already existing one.
12738 (Static_Array_Aggregate): New procedure to construct a positional
12739 aggregate that can be handled by the backend, when all bounds and
12740 components are compile-time known constants.
12741 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12742 types covering interface types into assignments.
12743 (Replace_Type): move to Build_Record_Aggr_Code.
12744 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12745 interface type, convert to the definite type of the aggregate itself,
12746 so that needed components are visible.
12747 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12748 components and the context is an extended return statement do not
12749 create a transient block for it, to prevent premature finalization
12750 before the return is executed.
12751 (Gen_Assign): Do not generate a call to deep adjust routine if the
12752 component type is itself an array of controlled (sub)-components
12753 initialized with an inner aggregate.
12754 (Component_Check): New name for Static_Check. This name is now more
12755 appropriate, and documentation is added which was missing.
12756 (Component_Check): Add test for bit aligned component value
12757 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12758 Tagged_Comps, name is more appropriate given added function below.
12759 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

12763 Robert Dewar <dewar@adacore.com>
12765 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12766 Terminated: Add unchecked type conversion from System.Address to
12767 System.Tasking.Task_Id when calling the predefined primitive
12769 Disable new Ada 05 accessibility check for JVM.NET targets, which
12770 cannot be implemented in a practical way.
12771 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12772 the sources always references the tag of the actual object. Therefore,
12773 if 'Tag is applied in the sources to class-wide interface objects we
12774 generate code that displaces "this" to reference the base of the object.
12775 (Expand_N_Attribute_Reference, case Size): Return specified size if
12776 known to front end.
12777 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12778 has code that displaces the pointer of the object to manage interface
12779 types. However this code must not be executed when the prefix is a
12780 subprogram. This bug caused the wrong expansion of the internally
12781 generated assignment that fills the dispatch table when the primitive
12782 is a function returning a class-wide interface type.
12783 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12784 Set_Attribute_Name for Name_Unaligned_Valid.
12786 2007-06-06 Ed Schonberg <schonberg@adacore.com>
12787 Gary Dismukes <dismukes@adacore.com>
12789 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12790 If the initialization is the equivalent aggregate of the initialization
12791 procedure of the type, do not remove it.
12792 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12793 initialized to null from having their expression reset to empty and
12794 note this exception in the comment.

12799 Gary Dismukes <dismukes@adacore.com>
12801 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
12802 Add "with" and "use" clauses for Sem_Attr.
12803 (Expand_Current_Value): Do not replace occurences of attribute
12804 references where the prefix must be a simple name.
12806 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
12807 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
12808 Attribute_Requires_Simple_Name_Prefix.
12809 (Name_Modifies_Prefix): Body of new function.
12810 (Requires_Simple_Name_Prefix): Body of new function.
12811 (Resolve_Attribute, case Access): Improve error message for case of
12812 mismatched conventions.
12813 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
12815 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12816 constrained subtype for a nominal unconstrained type, use its base type
12817 to check for conformance with the context.
12818 (Resolve_Attribute): Remove test of the access type being associated
12819 with a return statement from condition for performing accessibility
12820 checks on access attributes, since this case is now captured by
12821 Is_Local_Anonymous_Access.
12822 (Analyze_Access_Attribute): Set Address_Taken on entity
12823 (Analyze_Attribute, case Address): Set Address_Taken on entity
12824 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
12825 validating an access attribute whose prefix is a current instance.
12826 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
12827 applied to dispatching operations, if freezing is required then we set
12828 the attribute Has_Delayed_Freeze in the prefix's entity.
12829 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
12830 current scope if access of local subprogram taken
12831 (Analyze_Access_Attribute): Check legality of self-reference even if the
12832 expression comes from source, as when a single component association in
12833 an aggregate has a box association.
12834 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
12835 the prefix if it is a protected operation and the attribute is
12836 Unrestricted_Access.
12837 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
12838 reference to the base type of the context, to force a constraint check
12839 when the context is an access subtype with an explicit constraint.
12840 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
12841 node is rewritten as an interface conversion. leave unanalyzed after
12842 resolution, to ensure that type checking against the context will take

12846 Javier Miranda <miranda@adacore.com>
12847 Robert Dewar <dewar@adacore.com>
12849 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
12850 wrapper when the full view of the controlling type of an inherited
12851 function that dispatches on result implements interfaces.
12852 (Expand_N_Object_Declaration): In cases where the type of the
12853 declaration is anonymous access, create finalization list for it.
12854 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
12855 if the object has no explicit initialization, to match description of
12856 functionality of pragam Persistent_BSS.
12857 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
12858 new function to build static aggregates, to replace initialization call
12859 when static initialization is desired.
12860 (Freeze_Type): Generate a list controller for an access type whenever
12861 its designated type has controlled anonymous access discriminants.
12862 (Build_Equivalent_Aggregate): New procedure to compute a static
12863 aggregate to be used as default initialization for composite types,
12864 instead of a generating a call to the initialization procedure for the
12866 (Build_Initialization_Call): When available, replace a call to the
12867 initialization procedure with a copy of the equivalent static aggregate
12869 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
12870 declarations for objects of a class-wide interface type, rather than
12871 just identifiers, to prevent visibility problems.
12872 (Expand_N_Object_Declaration): When expanding the declaration for an
12873 object of a class-wide interface type, preserve the homonym chain of
12874 the original entity before exchanging it with that of the generated
12875 renaming declaration.
12876 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
12877 active, because there is no way to handle the exception.
12878 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
12879 to do a minimum decoration of the Access_Disp_Table list.
12880 (Expand_Record_Controller): Avoid the addition of the controller between
12881 the component containing the tag of a secondary dispatch table and its
12882 adjacent component that stores the offset to the base of the object.
12883 This latter component is only generated when the parent type has
12884 discriminants ---documented in Add_Interface_Tag_Components).
12885 (Apply_Array_Size_Check): Removed, no longer needed.
12886 (Expand_N_Full_Type_Declaration): If the type has anonymous access
12887 components, create a Master_Entity for it only if it contains tasks.
12888 (Build_Init_Procedure): Suppress the tag assignment compiling under
12890 (Freeze_Record_Type): Remove code associated with creation of dispatch
12892 (Init_Secondary_Tags): Update type of actuals when generating calls to
12893 Ada.Tags.Set_Offset_To_Top
12894 (Stream_Operation_OK): Disable use of streams compiling under no
12896 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
12897 if Has_Init_Expression set.
12898 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
12899 Register_Primitive, which provides the same functionality.
12900 (Requires_Init_Proc): Return false in case of interface types.
12901 (Add_Secondary_Tables): Use the new attribute Related_Interface to
12903 (Predefined_Primitive_Freeze): Do not assume that an internal entity
12904 is always associated with a predefined primitive because the internal
12905 entities associated with interface types are not predefined primitives.
12906 Therefore, the call to Is_Internal is replaced by a call to the
12907 function Is_Predefined_Dispatching_Operation.
12908 (Make_Eq_If): When generating the list of comparisons for the
12909 components of a given variant, omit the controller component that is
12910 present if the variant has controlled components.

12913 Hristian Kirtchev <kirtchev@adacore.com>
12914 Bob Duff <duff@adacore.com>
12916 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
12917 handle the creation of finalization lists and calls for nested
12918 coextensions when the root of the chains is part of a return statement.
12919 (Inside_A_Return_Statement): New function inside Complete_Coextension_
12921 (Expand_Record_Equality): Skip components that are interface types.
12922 (Displace_Allocator_Pointer): Add missing support for interface subtypes
12923 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
12924 with Rewrite_Coextension. Change the condition for detecting coextension
12926 (Is_Local_Access_Discriminant): Removed.
12927 (Rewrite_Coextension): New routine which rewrites a static coextension
12928 as a temporary and uses its unrestricted access in the construction of
12930 (Complete_Coextension_Finalization): New routine. Generate finalization
12931 attachment calls to all delayed coextensions.
12932 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
12933 the allocator is not a coextension itself and has delayed coextensions.
12934 If the current allocator is controlled, but also a coextension, delay
12935 the generation of the finalization attachment call.
12936 Rename local variable "Node" to "Nod" in order to avoid confusion with
12938 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
12939 limited types that are not inherently limited. Such an allocator is
12940 illegal, but is generated by the expander for a return statement, to
12941 copy the result onto the secondary stack. This is the only case where a
12942 limited object can be copied. Generate code to displace the pointer
12943 to the object if the qualified expression is a class-wide interface
12944 object. Such displacement was missing and hence the copy of the object
12946 (Apply_Accessibility_Check): Handle allocated objects initialized in
12948 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
12949 and Expand_Allocator_Expression. Allocating class-wide interface objects
12950 this routine displaces the pointer to the allocated object to reference
12951 the component referencing the corresponding secondary dispatch table.
12952 Expand_Allocator_Expression): Add missing support to allocate class-wide
12953 interface objects initialized with a qualified expression.
12954 (Get_Allocator_Final_List): Test for an anonymous access type that is a
12955 function result type, and use the finalization list associated with the
12956 function scope in that case (such an anonymous type should not be
12957 treated like an access parameter's type).

12963 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
12964 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
12965 required exception handler.
12966 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
12967 properly the case of a function whose return type is a limited
12968 class-wide interface type. Modify the code of the accessibility
12969 check to handle class-wide interface objects. In this case we need to
12970 displace "this" to reference the primary dispatch table to get access
12971 to the TSD of the object (to evaluate its accessibility level).
12972 (Expand_N_Extended_Return_Statement): Test for a tagged result type
12973 rather than a controlling result as one of the conditions for
12974 generating tests of the implicit BIP_Alloc_Form formal. The
12975 initialization assignment is also handled according to whether the
12976 result is tagged instead of controlling.
12977 In the case where the init assignment is inserted in the "then" part of
12978 the allocation conditional, rewrite the target to be a dereference of
12979 the implicit BIP_Object_Access formal.
12980 If the returned value is unconstrained and created on the secondary
12981 stack, mark the enclosing block and function so that the secondary
12982 stack is not reclaimed on return.
12983 Treat returns from functions with controlling results similarly to
12984 returns from functions with unconstrained result subtypes.
12985 If the object returned is unconstrained, and an allocator must be
12986 created for it, analyze the allocator once the block for the extended
12987 return is installed, to ensure that finalizable components
12988 of the expression use the proper finalization list. Guard the call to
12989 Move_Final_List with a check that there is something to finalize.
12990 (Make_Tag_Ctrl_Assignment): Use "old" handling
12991 of controlled type assignment for virtual machines, since new code uses
12992 unsupported features (such as direct access to bytes in memory).
12994 2007-06-06 Gary Dismukes <dismukes@adacore.com>
12995 Ed Schonberg <schonberg@adacore.com>
12997 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
12998 accessibility actual, check for the case of an aliased object that has
12999 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13000 we fall into processing for the attribute rather than the name of the
13002 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13003 formal has its address taken in the body, create a temporary to capture
13004 value. If the return type is a limited interface, do not treat the
13005 return value as Controlled.
13006 (Is_In_Place_Function): If the return type is a limited interface,
13007 treat as returning in place. The actual returned object may not always
13008 be limited, but the caller has to assume that it is returned in place.
13009 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13010 context of an allocator, use the correct finalization chain (that is,
13011 the chain belonging to the access type, rather than the chain belonging
13012 to the current scope).
13013 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13014 result type rather than a controlling result as a precondition for
13015 adding an allocation form actual to a build-in-place call.
13016 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13017 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13018 primitive in the dispatch tables. This work is now done by Make_DT when
13019 the type is frozen.
13020 (Register_Predefined_DT_Entry): Removed.
13021 (Add_Return): If end label is not present, use sloc of last statement
13022 for generated return statement in procedure, for better gdb behavior
13024 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13025 object address nodes to ensure proper processing by routines like
13027 (Expand_Call): Fix generation of validity check for parameter
13028 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13029 the allocation form parameter if the result subtype is constrained,
13030 except when the function has a controlling result.
13031 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13032 rather than Is_Controlled and Has_Controlled_Component, since we want to
13033 include class-wide result types in this treatment. Also test for a
13034 controlling result, since that also requires passing a finalization
13036 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13037 even when the result subtype is constrained, to handle calls involving
13038 controlling results.
13039 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13040 is now called even when the result subtype is constrained, to handle
13041 calls involving controlling results.
13042 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13043 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13044 now performs the test).
13045 (Make_Build_In_Place_Call_In_Object_Declaration):
13046 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13047 constrained, to handle calls involving controlling results.
13048 (Add_Return): Accomodate rewritten pattern from local raise to goto
13049 transformation, so that we still recognize an transfer statement
13050 and do the right thing here in that case.
13051 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13052 and end of subprogram code.
13053 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13054 support for primitives that are functions (without formals) with a
13055 controlling result.
13056 (Inherited_From_Formal): If the actual subtype has not generic parent
13057 type, it is not an actual for a formal derived type, and there is no
13058 operation to inherit from the formal.
13060 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13061 Thomas Quinot <quinot@adacore.com>
13063 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13064 inserted cleanup code appropriately for GDB use.
13065 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13066 exception handler for Deep_Adjust or Deep_Finalize.
13067 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13068 Raise_From_Controlled_Operation is available, use a call to that
13069 subprogram instead of a plain "raise Program_Error" node to raise
13070 Program_Error if an exception is propagated from an Adjust or Finalize
13072 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13073 appears in the optional statement list of a triggering alternative, the
13074 scope actions can be inserted directly there, and not in the list that
13075 includes the asynchronous select itself.
13077 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13078 Robert Dewar <dewar@adacore.com>
13079 Hristian Kirtchev <kirtchev@adacore.com>
13081 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13082 generated exception handler appropriately when debugging generated code.
13083 Deal properly with No_Exception_Propagation restriction mode.
13084 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13085 System.Address to System.Tasking.Task_Id when processing the result of
13086 the predefined primitive _disp_get_task_id.
13087 (Expand_N_Asynchronous_Select): Clarify comment.
13088 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13089 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13090 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13091 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13092 privals and for generated call to Complete_Entry_Body, for better gdb
13094 (Copy_Result_Type): Utility to construct a parameter and result profile
13095 for protected functions whose return type is an anonymous access to
13097 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13099 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13100 point when the local-raise-to-goto transformation has taken place.
13102 2007-06-06 Javier Miranda <miranda@adacore.com>
13103 Nicolas Setton <setton@adacore.com>
13105 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13106 functionality when the backend is generating code.
13107 Otherwise any serious error
13108 reported by the backend calling the frontend routine Error_Msg
13109 changes the Compilation_Mode to Check_Semantics, disables the
13110 functionality of this routine and causes the generation of
13111 spureous additional errors.
13113 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13114 debugging information now generated by the compiler for fat-pointer
13116 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13118 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13120 2007-06-06 Thomas Quinot <quinot@adacore.com>
13122 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13123 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13124 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13125 For a remote call to a function with a classwide return type, apply an
13126 E.4(18) check to the returned value.
13127 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13128 stream attributes of the designated type of an RACW, as they are not
13129 dispatching primitive operations.
13131 2007-06-06 Geert Bosch <bosch@adacore.com>
13133 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13135 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13137 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13138 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13140 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13142 2007-06-06 Javier Miranda <miranda@adacore.com>
13144 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13145 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13147 2007-06-06 Javier Miranda <miranda@adacore.com>
13149 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13150 deallocation of class-wide interface objects.
13151 (Expand_Dispatching_Constructor_Call): Take into account that if the
13152 result of the dispatching constructor is an interface type, the
13153 function returns a class-wide interface type; otherwise the returned
13154 object would be actual. The frontend previously accepted returning
13155 interface types because Expand_Interface_Actuals silently performed
13156 the management of the returned type "as if" it were a class-wide
13158 (Expand_Dispatching_Constructor_Call): Replace call to
13159 Make_DT_Access_Action by direct call to Make_Function_Call.
13161 2007-06-06 Robert Dewar <dewar@adacore.com>
13162 Ed Schonberg <schonberg@adacore.com>
13164 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13165 compute masking constant, since we now set Esize properly to the
13167 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13168 to match the alignment.
13169 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13170 packed arrays of 8 bits or less.
13172 * freeze.adb (Freeze_Entity): When freezing the formals of a
13173 subprogram, freeze the designated type of a parameter of an access type
13174 only if it is an access parameter.
13175 Increase size of C convention enumeration object
13176 (Freeze_Entity, array type case): Make sure Esize value is properly
13177 adjusted for the alignment if it is known.
13178 (Freeze_Entity, array type case): When checking bit packed arrays for
13179 the size being incorrect, check RM_Size, not Esize.
13180 (Freeze_Record_Type): Check for bad discriminated record convention
13181 (In_Exp_Body): Return true if the body is generated for a subprogram
13182 renaming, either an attribute renaming or a renaming as body.
13183 (Check_Itype): If the designated type of an anonymous access component
13184 is a non-protected subprogram type, indicate that it is frozen, to
13185 prevent out-of-scope freeze node at some subsequent call.
13186 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13187 only if the subprogram is neither imported nor exported, as well as the
13188 NCA descriptor class if the subprogram is exported.

13191 Arnaud Charlet <charlet@adacore.com>
13192 Robert Dewar <dewar@adacore.com>
13193 Gary Dismukes <dismukes@adacore.com>
13195 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13196 default initialization on an imported object, when there is no
13197 initialization call generated for it.
13198 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13201 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13202 Static_Elaboration_Desired.
13203 Remove pragma Thread_Body.
13204 Implement a new pragma No_Body
13205 Removes the Explicit_Overriding pragma
13206 Remove Optional_Overriding pragma
13207 (Prag): Deal with Universal_Aliasing.
13208 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13209 Pragma_CIL_Constructor): New names.
13211 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13212 uses the equivalent aggregate of a type must be treated as an implicit
13214 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13215 has none of the other categories.
13216 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13217 to apply Import to an object renaming declaration.
13219 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13220 from a C++ class should be declared as limited and that it will be
13221 considererd limited.
13222 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13223 should be declared as limited and that it will be considererd limited.
13224 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13225 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
13226 (Analyze_Pragma): Deal with Universal_Aliasing.
13227 (Sig_Flags): Likewise.
13228 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
13229 (Overflow_Checks_Unsuppressed): New flag.
13230 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
13231 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
13232 case of JVM or .NET targets, and compiling user code.
13233 Add debugging convenience routine rv

13242 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
13243 set to value that does not match base type size.
13245 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13247 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13248 object of a limited type can be initialized with a call to a function
13249 that returns in place. If the limited type has unknown discriminants,
13250 and the underlying type is a constrained composite type, build an actual
13251 subtype from the function call, as is done for private types.
13252 (Side_Effect_Free): An expression that is the renaming of an object or
13253 whose prefix is the renaming of a object, is not side-effect free
13254 because it may be assigned through the renaming and its value must be
13255 captured in a temporary.
13256 (Has_Controlled_Coextensions): New routine.
13257 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13258 as is done for other limited types.
13259 (Non_Limited_Designated_Type): new predicate.
13260 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
13262 Remove all handling of with_type clauses.

13266 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
13267 checksum if the main source could not be parsed.
13268 (Loat_Unit): When processing a child unit, determine properly whether
13269 the parent unit is a renaming when the parent is itself a child unit.
13270 Remove handling of with_type clauses.
13272 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

13284 Robert Dewar <dewar@adacore.com>
13286 * frontend.adb (Frontend): Return immediately if the main source could
13287 not be parsed, because of preprocessing errors.
13289 * gnat1drv.adb (gnat1drv): Handle RE_Not_Available gracefully.

13305 Ed Schonberg <schonberg@adacore.com>
13307 * g-comlin.ads, g-comlin.adb:
13308 Add new warning for renaming of function return objects
13310 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
13311 (Tree_Read): Use size of object instead of type'object_size, since the
13312 latter is incorrect for packed array types.
13313 (Tree_Write): Same fix
13315 * opt.ads: Add new warning for renaming of function return objects
13316 (Generating_Code): New boolean variable used to indicate that the
13317 frontend as finished its work and has called the backend to process
13318 the tree and generate the object file.

13326 (Warn_On_Unrepped_Components): New flag.
13328 * sem_ch8.adb (Check_Library_Unit_Renaming): Check that the renamed
13329 unit is a compilation unit, rather than relying on its scope, so that
13330 Standard can be renamed.
13331 (Analyze_Object_Renaming): Add new warning for renaming of function
13333 Also reject attempt to rename function return object in Ada 83 mode.
13334 (Attribute_Renaming): In case of tagged types, add the body of the
13335 generated function to the freezing actions of the type.
13336 (Find_Type): A protected type is visible right after the reserved word
13337 "is" is encountered in its type declaration. Set the entity and type
13338 rather than emitting an error message.
13339 (New_Scope): Properly propagate Discard_Names to inner scopes
13340 (Check_Nested_Access): New procedure.
13341 (Has_Nested_Access, Set_Has_Nested_Access): New procedures.

13355 * g-debpoo.ads, g-debpoo.adb (Free_Physically.Free_Blocks): Use the
13356 absolute value of Header.Block_Size when displaying the freed physical
13358 (Allocate): Compute Storage_Address using Integer_Address, not
13359 Storage_Offset, because the range of Storage_Offset may not be large
13361 (Configure): New parameter Low_Level_Traces
13362 (Allocate, Deallocation, Free_Physically): Added low-level traces
13363 (Configure): new parameter Errors_To_Stdout.
13364 (Output_File): new subprogram
13365 (Deallocate, Dereference): Send error messages to the proper stream
13366 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
13367 documented. Previous code would send it to the current output file
13368 defined in GNAT.IO, which might not be stdout
13369 (Is_Valid): Adjust comment to mention that a positive reply means that
13370 Header_Of may be used to retrieve the allocation header associated with
13371 the subprogram Storage address argument. Return False early if this
13372 address argument is misaligned.
13374 2007-06-06 Vincent Celier <celier@adacore.com>

13388 * gnatlink.adb (Gnatlink): Do not specify -static-libgcc when --LINK=
13390 Correct error message when invocation of the linker fails
13391 Add explicit size clause for the C imported variables
13392 Object_List_File_Supported and Using_GNU_Linker to emphasize that
13393 we expect char size.
13394 Read target parameters earlier, since this is needed to set
13395 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
13398 2007-06-06 Vincent Celier <celier@adacore.com>
13401 Add 3 spaces before the default project directory when displaying
13402 the project search path.
13403 Add new command line switch '-l' to display license information.
13405 2007-06-06 Vasiliy Fofanov <fofanov@adacore.com>
13407 * gmem.c: Add support for timestamps on memory operations.
13409 * memtrack.adb, gnatmem.adb: Add support for timestamps on memory
13410 operations (not used currently, just foundation for future
13411 enhancements). Add possibility to perform full dump of gmem.out file.
13412 (Print_Back_Traces): Declare accesses to root arrays constants since
13413 they aren't modified.

13779 associated with dispatch tables is known at compile time.
13780 (Get_Value): If an association in a record aggregate has a box
13781 association, and the corresponding record component has a default
13782 expression, always copy the default expression, even when the

14883 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
14885 (Resolve_Actuals): If an actual is an allocator for an access parameter,
14886 the master of the created object is the innermost enclosing statement.
14887 (Remove_Conversions): For a binary operator, check if type of second

15130 attempt to derive from a synchronized tagged type.

15135 that use (a subtype of) the class-wide type of the enclosing type.
15136 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15137 Derived_Type for Prev formal on call to
15138 Check_Anonymous_Access_Components rather than Empty.
15139 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15140 a record extension in deciding whether to create a class-wide type,

15194 gnatbind if the ALI file effectively exists.
15195 (Initialize): Add the directory where gnatmake is invoked in front of
15196 the path if it is invoked from a bin directory, even without directory

15221 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15222 when -gnatg is not specified.
15223 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15224 there is no need to generate always a record_definition_node in case
15225 of synchronized interface types.
15226 (SIS_Entry_Active): Initialize global variable to False
15227 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

15248 If the array component is a discriminated record, the array aggregate
15249 is non-static even if the component is given by an aggregate with
15251 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
15252 (Convert_Aggr_In_Allocator): If the allocator is for an access
15253 discriminant and the type is controlled. do not place on a finalization
15254 list at this point. The proper list will be determined from the

15257 initialize record controller if needed, before the components, to ensure
15258 that they are properly finalized.

15273 succeed in that case, even when the expression originates from a
15274 parameter of the containing subprogram.
15275 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15276 under No_Dispatching_Calls restriction. During the semantic analysis
15277 we already notified such violation.
15278 (Tagged_Membership): Constant folding. There is no need to check
15279 the tag at run-time if the type of the right operand is non
15280 class-wide abstract.

15295 initialize most the TSD components by means of an aggregate.
15296 Modify the declaration of the object containing the TSD
15297 because we now expand code that has a higher level of abstraction.
15298 The TSD has a discriminant containing the Inheritance Depth Level,
15299 value that is used in the membership test but also to fix the size
15300 of the table of ancestors.
15301 (Expand_Interface_Conversion): Insert function body at the closest place
15302 to the conversion expression, to prevent access-before-elaboration
15303 errors in the backend.

15305 compiling under restriction No_Dispatching_Calls plus code cleanup.
15306 Code reorganization plus removal of calls to Set_Num_Prim_Ops

15328 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
15329 (Expand_Dispatching_Call): Replace generation of call to the run-time
15330 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15331 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15333 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15334 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

15337 (Get_Remotely_Callable): Subprogram removed.
15338 (Init_Predefined_Interface_Primitives): Replace generation of call to
15339 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
15342 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15343 First (Parameter_Associations ()) with the call to First_Actual that
15344 returns an actual parameter expression for both named and positional
15347 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15348 check violation of restriction No_Dispatching_Calls.
15349 (Check_Controlling_Type): A formal of a tagged incomplete type is a
15350 controlling argument.

15353 First/Next_Component_Or_Discriminant
15354 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
15355 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15356 specify Any_Limited_Interface, and this functionality is already
15357 provided by the function Has_Abstract_Interfaces.
15358 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15359 support concurrent types implementing interfaces.
15360 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15361 specify kind Any_Limited_Interface, and this functionality is already
15362 provided by the function Has_Abstract_Interfaces.
15363 (Remove_Side_Effects): replace Controlled_Type by
15364 CW_Or_Controlled_Type whenever the issue is related to
15365 using or not the secondary stack.
15367 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
15368 P_Interface_Type_Definition to fulfill the new interface (the formal
15369 Is_Synchronized is no longer required).

15381 anonymous, use finalization list of enclosing dynamic scope.
15382 (Expand_N_Package_Declaration): For a library package declaration
15383 without a corresponding body, generate RACW subprogram bodies in the
15384 spec (just as we do for the task activation call).
15385 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15386 Is_Abstract_Type. Make sure these are called only when appropriate.
15387 Remove all code for DSP option
15388 (CW_Or_Controlled_Type): new subprogram.

15394 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15395 parameter. If it is set to true, return a result capped according to
15396 the global upper bound for the index of an entry family.
15397 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
15398 (Build_Find_Body_Index): Adjust for above change.
15399 (Entry_Index_Expression): Likewise.

15404 Family_Size with 'Cap' set to true.
15405 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15406 a protected version of an operation declared in the private part of
15407 a protected object, because they may be invoked through a callback.
15408 (Set_Privals): If the type of a private component is an anonymous access
15409 type, do not create a new itype for each protected body.
15410 If the body of a protected operation creates
15411 controlled types (including allocators for class-widetypes), the
15412 body of the corresponding protected subprogram must include a
15414 (Build_Activation_Chain_Entity): Build the chain entity for extended
15416 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15417 to determine whether operation overrides an inherited primitive.
15418 (Build_Wrapper_Spec): Add code to examine the parents while looking
15419 for a possible overriding candidate.
15420 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15421 hold an actual parameter value since its initialization is separated
15422 from the the declaration. Prevents errors on null-excluding access

15426 Pablo Oliveira <oliveira@adacore.com>
15428 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15429 Do an Unchecked_Conversion to handle the passage from the Underlying

15431 Build_From_Any_Call.
15432 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15433 E_Constant, depending upon Variable formal.
15434 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15435 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15436 parameter that requires an extra constrained parameter, declare
15437 temporary for actual as a variable, not a constant.
15438 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15439 the unit being compiled is the one that contains the stub type.
15440 Change primitive operation name for the RACW associated with a RAS
15441 from Call to _Call so it cannot clash with any legal identifier.
15442 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15444 (Append_RACW_Bodies): New subprogram.
15445 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15446 Add_Receiving_Stubs_To_Declarations functions.
15447 When expanding a package body, this list correspond to the

15452 registering the receiving stubs at the end of the 'Stmts' list.
15453 (RCI_Package_Locator): Pass the new Version generic formal when
15454 instantiating a RCI_Locator package.
15455 (Build_From_Any_Function): To compute the High bound for an
15456 unconstrained array actual, we add the Low bound with the length.
15457 Thus we must convert the low bound and the length to an appropriate
15458 type before doing the sum.
15459 (Build_Subprogram_Receiving_Stubs, PolyORB):
15460 * Retrieve the extra formals parameters at the
15461 end of the parameter stream.
15462 * Use Move_Any_Value to write back out parameters
15463 after executing the request as it is more efficient
15464 than Copy_Any_Value.
15465 * Build the any containing Extra Formals with the
15466 appropriate typecode.
15467 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15468 empty Component_List.
15469 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15470 the tree the declaration for an object that serves as actual parameter
15471 in server-side stubs.

15481 function with the first not implicit parent type.
15482 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15483 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15484 typecode from the Etype. Therefore we retrieve the correct typecode
15485 with a call to Get_Any_Type.
15486 (Copy_Specification): Do controlling formal type substitution based on
15487 Is_Controlling_Formal flag, instead of caller-provided object type.
15488 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15489 a RACW primitive operation, we might get a subprogram declaration for an
15490 ancestor of the RACW designated type (not for the designated type
15491 itself), in the case where this operation is inherited. In this case we
15492 have no easy means of determining the original tagged type for which
15493 the primitive was declared, so instead we now rely on
15494 Copy_Specification to use the Is_Controlling_Formal flag to determine
15495 which formals require type substitution.

15503 handler unsuitable as a target for a local raise statement.
15504 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15505 run-time subprogram CW_Membership by call to Build_CW_Membership.
15506 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15507 by a function call, a temporary must be created before expanding the
15508 Constructor_Call itself, to prevent out-of-order elaboration in the
15509 back-end when stack checking is enabled..
15511 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15513 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the

15636 * mingw32.h (S2WSU): New macro to convert from a string to a
15637 wide-string using the UTF-8 encoding. The S2WS macro supports now only
15638 standard 8bits encoding.
15639 (WS2SU): As above but converting from wide-sring to string.
15640 This is needed as it is necessary to have access to both versions in the
15641 runtime for the form parameter encoding support.
15642 This set of patch add support for the encoding form parameter.
15643 (S2WS): Improve implementation to handle cases where the filename is not
15644 UTF-8 encoded. In this case we default to using the current code page
15645 for the conversion.
15647 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
15648 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

15692 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
15693 __gnat_adjust_context_for_raise.
15694 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
15695 implementation of floating point operations as native x86 targets.
15696 So the FPU should be initialized in the same way using finit. Fix
15697 floating point operations accuracy issues.
15698 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
15699 member in struct sigaction, so as to avoid warning for incompatible

15717 * lib-xref.ads, lib-xref.adb:
15718 Modify the loop that collects type references, to include interface
15719 types that the type implements. List each of these interfaces when
15720 building the entry for the type.
15721 (Generate_Definition): Initialize component Def and Typ of new entry
15722 in table Xrefs, to avoid to have these components unitialized.
15723 (Output_References): Split Is_Abstract flag into
15724 Is_Abstract_Subprogram and Is_Abstract_Type.
15725 (Generate_Reference): Add barrier to do not generate the warning
15726 associated with Ada 2005 entities with entities generated by the

15766 2007-04-06 Robert Dewar <dewar@adacore.com>
15768 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
15769 it no longer destroys the contents of Name_Buffer or Name_Len and
15770 non-standard and invalid names are handled better.
15771 (Get_Decoded_Name_String): Improve performance by using
15772 Name_Has_No_Encodings flag in the name table.
15773 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
15774 Used for debugging printouts.

15777 Javier Miranda <miranda@adacore.com>
15778 Bob Duff <duff@adacore.com>
15780 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
15781 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15782 there is no need to generate always a record_definition_node in case
15783 of synchronized interface types.
15784 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
15785 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
15786 illegal in Ada 95, in cases where it is legal. Change the warnings to
15787 errors in other cases. Don't give the error unless the "not null"
15788 parses properly. Correct the source position at which the error occurs.
15789 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
15790 P_Null_Exclusion, to suppress "not null" warnings.

15841 Run_Path_Option, Toolchain_Version.
15842 Entry for pragma Unreferenced_Objects
15844 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
15845 switches, without repetition of "eD". Make sure that last character of
15846 -gnatep= switch is not taken as -gnat switch character.
15847 Complete rewrite of circuit for handling saving compilation options
15848 Occasioned by need to support dot switchs for -gnatw, but cleans up

15866 the default project path, initially done during elaboration of the
15868 If the prefix returned by Sdefault is null, get the prefix from a call
15869 to Executable_Prefix_Path.
15870 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
15873 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
15874 canonical directory name to open the directory from which files are
15876 (Record_Other_Sources): Idem.
15877 (Locate_Directory): Add the possibility to create automatically missing
15878 directories when Setup_Projects is True.
15879 Call Locate_Directory so that the directory will be created when
15880 Setup_Projects is True, for object dir, library dir, library ALI dir,
15881 library source copy dir and exec dir.
15883 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
15886 2007-04-06 Robert Dewar <dewar@adacore.com>

15920 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
15921 full word is no longer compared twice.
15923 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15925 * sem_ch10.adb (Install_Limited_Context_Clauses.
15926 Expand_Limited_With_Clause): Use a new copy of selector name in the
15927 call to Make_With_Clause. This fixes the tree structure for ASIS
15928 purposes. Nothing is changed in the compiler behaviour.
15929 (Process_Body_Clauses): Handle properly use clauses whose prefix is
15930 a package renaming.
15931 (Install_Limited_With_Clauses): Do not install non-limited view when it
15932 is still incomplete.
15934 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15935 Gary Dismukes <dismukes@adacore.com>
15937 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
15938 when capturing size information, instead of base type, which for a
15939 formal array type will be the unconstrained type.
15940 (Analyze_Formal_Object_Declaration): Add check for illegal default
15941 expressions for a formal in object of a limited type.
15942 (Instantiate_Object): Ditto.
15943 (Check_Formal_Package_Instance): Skip entities that are formal objects,
15944 because they were defaulted in the formal package and no check applies
15946 (Check_Formal_Package_Instance): Extend conformance check to other
15947 discrete types beyond Integer.
15948 (Process_Default): Copy directly the unmatched formal. A generic copy
15949 has already been performed in Analyze_Formal_Package.
15950 (Analyze_Associations): If a formal subprogram has no match, check for
15951 partial parametrization before looking for a default, to prevent
15953 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
15954 not set the instantiation environment before analyzing the actuals.
15955 Fixes regression on 8515-003 with implementation of AI-133.
15956 Set_Instance_Env checks whether the generic unit is a predefined
15957 unit, in which case the instance must be analyzed with the latest Ada
15958 mode. This setting must take place after analysis of the actuals,
15959 because the actuals must be analyzed and frozen in the Ada mode extant
15960 outside of the current instantiation.
15961 (Save_Env, Restore_Env): Preserve and restore the configuration
15962 parameters so that predefined units can be compiled in the proper Ada
15964 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
15965 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
15966 and Is_Abstract_Type.
15967 (Analyze_Formal_Package): For better error recovery, Add exception
15968 handler to catch Instantion_Error, which can be raised in
15969 Analyze_Associations
15971 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15972 Bob Duff <duff@adacore.com>
15973 Gary Dismukes <dismukes@adacore.com>
15975 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
15976 prefix type is a discriminated subtype of the type of the formal.
15977 (Analyze_Allocator): Collect all coextensions regardless of the context.
15978 Whether they can be allocated statically is determined in exp_ch4.
15979 (Analyze_Selected_Component): If the prefix is a limited view and the
15980 non-limited view is available, use the non-limited one.
15981 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
15982 therefore illegal), suggest a qualified expression rather than a type
15983 conversion, because a type conversion would be illegal in this context.
15984 (Anayze_Allocator): Trace recursively all nested allocators so that all
15985 coextensions are on the corresponding list for the root. Do no mark
15986 coextensions if the root allocator is within a declaration for a stack-
15987 allocated object, because the access discriminants will be allocated on
15989 (Analyze_Call): Remove restriction on calls to limited functions for the
15990 cases of generic actuals for formal objects, defaults for formal objects
15991 and defaults for record components.
15992 (Analyze_Allocator): Before analysis, chain coextensions on the proper
15993 element list. Their expansion is delayed until the enclosing allocator
15994 is processed and its finalization list constructed.
15995 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
15996 for an operation with the given name among the primitive operations of
15997 the corresponding record type.
15998 (Analyze_Selected_Component): If the prefix is a task type that
15999 implements an interface, and there is no entry with the given name,
16000 check whether there is another primitive operation (e.g. a function)
16002 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16003 properly the indexing of a function call written in prefix form, where
16004 the function returns an array type, and all parameters of the function
16005 except the first have defaults.
16006 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16007 the original operands, rather than relocating them, for efficiency and
16008 to work properly when an operand is overloaded.
16009 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16010 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16011 (Analyze_Selected_Component): If the prefix is a private extension, only
16012 scan the visible components, not those of the full view.
16013 (Try_Primitive_Operation): If the operation is a procedure, collect all
16014 possible interpretations, as for a function, because in the presence of
16015 classwide parameters several primitive operations of the type can match
16016 the given arguments.
16018 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16019 Robert Dewar <dewar@adacore.com>
16021 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16022 tag-indeterminate call to an abstract function, when the left-hand side
16024 (Analyze_Loop_Statement): Improve detection of infinite loops
16026 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16027 Thomas Quinot <quinot@adacore.com>
16029 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16030 out of Analyze_Package_Declaration, because processing must be applied
16031 to package bodies as well, for deferred constants completed by pragmas.
16032 (Analyze_Package_Declaration): When the package declaration being
16033 analyzed does not require an explicit body, call Check_Completion.
16034 (May_Need_Implicit_Body): An implicit body is required when a package
16035 spec contains the declaration of a remote access-to-classwide type.
16036 (Analyze_Package_Body): If the package contains RACWs, append the
16037 pending subprogram bodies generated by exp_dist at the end of the body.
16038 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16039 Is_Abstract_Subprogram and Is_Abstract_Type.
16040 (Preserve_Full_Attributes): The full entity list is not an attribute
16041 that must be preserved from full to partial view.
16043 * sem_dist.adb (Add_RAS_Dereference_TSS):
16044 Change primitive name to _Call so it cannot clash with any legal
16045 identifier, and be special-cased in Check_Completion.
16046 Mark the full view of the designated type for the RACW associated with
16047 a RAS as Comes_From_Source to get proper view switching when installing
16048 private declarations.
16049 Provite a placeholder nested package body along with the nested spec
16050 to have a place for Append_RACW_Bodies to generate the calling stubs
16051 and stream attributes.
16053 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16054 Robert Dewar <dewar@adacore.com>
16056 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16057 that is a limited view, check the non-limited view if available.
16058 (Undefined): Refine error message for missing with of Text_IO
16059 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16060 to distinguish real missing with cases.
16061 Fix format of all missing with messages
16062 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16063 renaming as body when renamed entity is abstract.
16065 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16066 Javier Miranda <miranda@adacore.com>
16068 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16069 predicate recursive, to handle complex expressions on literals whose
16070 spurious ambiguity comes from the abstract interpretation of some
16072 (Interface_Present_In_Ancestor): Add support to concurrent record
16074 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16075 Is_Abstract_Subprogram and Is_Abstract_Type.
16077 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16078 Javier Miranda <miranda@adacore.com>
16080 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16081 dereference of a local object R created as a reference to another
16082 object O, use the access level of O.
16083 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16084 rather than local Same_Formal_Type, to check whether protected operation
16085 overrides an inherited one.
16086 (Same_Formal_Type): New predicate, used when matching signatures of
16087 overriding synchronized operations, to handle the case when a formal
16088 has a type that is a generic actual.
16089 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16090 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16091 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16092 syntactic ambiguities involving indexing of function calls that return
16094 (Abstract_Interface_List): New subprogram that returns the list of
16095 abstract interfaces associated with a concurrent type or a
16096 concurrent record type.
16097 (Interface_Present_In_Parent): New subprogram used to check if a
16098 given type or some of its parents implement a given interface.
16099 (Collect_Abstract_Interfaces): Add support for concurrent types
16100 with interface types.
16101 (Has_Abstract_Interfaces): Add support for concurrent types with
16103 (Is_Parent): New subprogram that determines whether E1 is a parent
16104 of E2. For a concurrent type its parent is the first element of its
16105 list of interface types; for other types this function provides the
16106 same result than Is_Ancestor.
16107 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16108 (Collect_Synchronized_Interfaces): Removed because the subprogram
16109 Collect_Abstract_Interfaces provides this functionality.
16110 (Collect_Abstract_Interfaces): Minor update to give support to

16446 anonymous access types.
16447 (Valid_Conversion): For a conversion to a numeric type occurring in an

17019 by themselves. Disabling those checks must also be done for task types,
17020 where discriminants may be used for the bounds of entry families.
17021 (Apply_Address_Clause_Check): Remove side-effects if address expression
17022 is non-static and is not the name of a declared constant.

17034 rewritten replacement for Apply_Alignment_Check
17035 (Get_E_Length/Get_E_First_Or_Last): Add missing barrier to ensure that
17036 we request a discriminal value only in case of discriminants.
17037 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17038 assignments where the target subtype is unconstrained and the target
17039 object is a parameter or dereference (other aliased cases are known
17040 to be unconstrained).

17066 (Is_Return_By_Reference_Type): Rename Is_Return_By_Reference_Type
17067 to be Is_Inherently_Limited_Type, because return-by-reference has

17120 Make use of concatenation now allowed in compiler
17121 (Executable_Prefix.Get_Install_Dir): First get the full path, so that
17122 we find the 'lib' or 'bin' directory even when the tool has been
17123 invoked with a relative path.

17126 * osint-c.ads, osint-c.adb:
17127 Implement new -gnatl=xxx switch to output listing to file

17154 the parent part is a build-in-place function call, generate assignments.
17155 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17156 are build-in-place function calls.
17157 (Replace_Self_Reference): New subsidiary of
17158 Make_OK_Assignment_Statement, to replace an access attribute that is a
17159 self-reference into an access to the appropriate component of the
17160 target object. Generalizes previous mechanism to handle self-references
17161 nested at any level.
17162 (Is_Self_Referential_Init): Remove, not needed.
17163 (Is_Self_Referential_Init): New predicate to simplify handling of self
17164 referential components in record aggregates.
17165 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
17166 check for presence of entity before checking for self-reference.
17167 (Has_Default_Init_Comps): Return True if a component association is a
17168 self-reference to the enclosing type, which can only come from a
17169 default initialization.
17170 (Make_OK_Assignment_Statement): If the expression is of the form
17171 Typ'Acc, where Acc is an access attribute, the expression comes from a
17172 default initialized self-referential component.
17173 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17174 that has been derived from several abstract interfaces we must also
17175 initialize the tags of the secondary dispatch tables.

17178 Thomas Quinot <quinot@adacore.com>
17179 Javier Miranda <miranda@adacore.com>
17180 Robert Dewar <dewar@adacore.com>
17183 (Expand_Access_To_Protected_Op): If the context indicates that an access
17184 to a local operation may be transfered outside of the object, create an
17185 access to the wrapper operation that must be used in an external call.
17186 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17187 target, pass the Valid attribute applied to a floating-point prefix on
17188 to the back end without expansion.
17189 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17190 the allocated storage when it is specified by a per-object expression.
17191 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17192 Nothing to do here, the attribute has been rewritten during semantic

17196 (Find_Fat_Info): Handle case of universal real
17197 (Expand_Access_To_Protected_Op): Fix use of access to protected
17198 subprogram from inside the body of a protected entry.
17199 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
17200 'Access and 'Unrestricted_Access, to transform the attribute reference
17201 into a fat pointer.
17202 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17203 subcomponent's enclosing variable is aliased with a constrained subtype.
17204 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17205 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17206 an aliased prefix must be known to be constrained in order to use True
17207 for the attribute value, and now it's possible for some aliased views
17208 to be unconstrained.
17210 2006-10-31 Robert Dewar <dewar@adacore.com>
17212 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17213 (Expand_Entity_Reference): Correct error of not handling subprogram
17214 formals in current_value processing.
17216 2006-10-31 Javier Miranda <miranda@adacore.com>
17217 Robert Dewar <dewar@adacore.com>
17218 Ed Schonberg <schonberg@adacore.com>
17219 Gary Dismukes <dismukes@adacore.com>
17221 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17222 register in the final list objects containing class-wide interfaces;
17223 otherwise we incorrectly register the tag of the interface in the final
17225 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17226 generate the wrapper if the parent primitive is abstract. This is
17227 required to report the correct error message.
17228 (Expand_N_Subtype_Indication): Do validity checks on range
17229 (Clean_Task_Names): If an initialization procedure includes a call to
17230 initialize a task (sub)component, indicate that the procedure will use
17231 the secondary stack.
17232 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17233 compatibility for interfacing with CPP by default.
17234 (Expand_N_Object_Declaration): Only build an Adjust call when the
17235 object's type is a nonlimited controlled type.
17236 * exp_ch3.adb: Add with and use of Exp_Ch6.
17237 (Expand_N_Object_Declaration): Check for object initialization that is a
17238 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17239 Object_Declaration to the call.
17240 (Freeze_Type): When the designated type of an RACW was not frozen at the
17241 point where the RACW was declared, validate the primitive operations
17242 with respect to E.2.2(14) when it finally is frozen.
17243 (Build_Initialization_Call,Expand_Record_Controller): Rename
17244 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17245 return-by-reference has no meaning in Ada 2005.
17246 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17247 to register tag of the immediate ancestor interfaces in the
17248 run-time structure.
17249 (Init_Secondary_Tags): Moved to the specification to allow the
17250 initialization of extension aggregates with abstract interfaces.
17251 (Build_Master_Renaming): Make public, for use by function declarations
17252 whose return type is an anonymous access type.
17253 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17254 Insert_List_Before_And_Analyze after the generation of the specs
17255 associated with null procedures.
17256 (Expand_Tagged_Root): Update documentation in its specification.
17257 (Init_Secondary_Tags): Update documentation.
17258 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17259 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17260 then generate code to inherit the contents of the dispatch table
17261 directly from the ancestor.
17262 (Expand_Record_Controller): Insert controller component after tags of
17263 implemented interfaces.
17264 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17265 create null procedure overridings when null procedures are inherited
17267 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17268 declarations for overriding null primitives inherited from interfaces.
17269 (Is_Null_Interface_Procedure): New function in
17270 Make_Null_Procedure_Specs.
17271 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17272 immediate ancestor of a tagged type is an abstract interface type we
17273 must generate the specification of the predefined primitives associated
17274 with controlled types (because the dispatch table of the ancestor is
17275 null and hence these entries cannot be inherited). This is required to
17276 elaborate well the dispatch table.

17286 (Expand_N_In): Do validity checks on range
17287 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17288 (Expand_N_Allocator): For "new T", if the object is constrained by
17289 discriminant defaults, allocate the right amount of memory, rather than
17290 the maximum for type T.
17291 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17292 when the allocator is initialized by a build-in-place call, since the
17293 allocator is already rewritten as a reference to the function result,
17294 and this prevents an unwanted duplication of the function call.
17295 Add with and use of Exp_Ch6.
17296 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17297 is a call to build-in-place function and apply
17298 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17299 untagged designated types).
17300 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17301 optimization if source or target is biased.
17302 (Expand_N_Allocator): Add comments for case of an allocator within a
17303 function that returns an anonymous access type designating tasks.
17304 (Expand_N_Allocator): apply discriminant checks for access
17305 discriminants of anonymous access types (AI-402, AI-416)

17310 Ed Schonberg <schonberg@adacore.com>
17312 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17314 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17315 (Expand_N_Assignment_Statement): Call
17316 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17317 build-in-place function call. Currently, this can happen only for
17318 assignments that come from aggregates.
17319 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17320 in order to alleviate the upward compatibility introduced by AI-318.
17321 (Expand_N_Extended_Return_Statement): Add support for handling the
17322 return object as a build-in-place result.
17323 (Expand_Non_Function_Return): Implement simple return statements nested
17324 within an extended return.
17325 (Enable_New_Return_Processing): Turn on the new processing of return
17327 (Expand_Non_Function_Return): For a return within an extended return,
17328 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17329 (Expand_N_Extended_Return_Statement): Implement AI-318
17330 (Expand_Simple_Function_Return): Ditto.
17331 (Expand_N_If_Statement): Handle new -gnatwt warning
17332 (Expand_N_Case_Statement): Handle new -gnatwt warning
17333 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17334 a protected object.
17335 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17336 validity checking of assignments to elementary record components.
17337 (Expand_N_Return_Statement): return Class Wide types on the secondary
17338 stack independantly of their controlled status since with HIE runtimes,
17339 class wide types are not potentially controlled anymore.
17341 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17344 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17345 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17346 it expects a block, procedure, or task. The return statement will get
17347 turned into a block, and Expand_Cleanup_Actions will happen then.
17349 2006-10-31 Robert Dewar <dewar@adacore.com>
17350 Ed Schonberg <schonberg@adacore.com>
17351 Bob Duff <duff@adacore.com>
17352 Gary Dismukes <dismukes@adacore.com>
17354 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17356 (Expand_Inlined_Call): Tagged types are by-reference types, and
17357 therefore should be replaced by a renaming declaration in the expanded
17358 body, as is done for limited types.
17359 (Expand_Call): If this is a call to a function with dispatching access
17360 result, propagate tag from context.
17361 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17363 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17364 build-in-place when the right-hand side of an assignment is a
17365 build-in-place function call.
17366 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17367 of the explicit dereference of the allocator to the result subtype of
17368 the build-in-place function. This is needed to satisfy type checking
17369 in cases where the caller's return object is created by an allocator for
17370 a class-wide access type and the type named in the allocator is a
17372 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17373 conversion of the reference to the declared object to the result subtype
17374 of the build-in-place function. This is needed to satisfy type checking
17375 in cases where the declared object has a class-wide type. Also, in the
17376 class-wide case, change the type of the object entity to the specific
17377 result subtype of the function, to avoid passing a class-wide object
17378 without explicit initialization to the back end.
17379 (Register_Interface_DT_Entry): Moved outside the body of
17380 Freeze_Subprogram because this routine is now public; it is called from
17381 Check_Dispatching_Overriding to handle late overriding of abstract
17382 interface primitives.
17383 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17384 adding an implicit access actual on a call to a build-in-place function.
17385 (Expand_Actuals): Test for an actual parameter that is a call to a
17386 build-in-place function and apply
17387 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17388 (Is_Build_In_Place_Function): New function to determine whether an
17389 entity is a function whose calls should be handled as build-in-place.
17390 (Is_Build_In_Place_Function_Call): New function to determine whether an
17391 expression is a function call that should handled as build-in-place.
17392 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17393 calls to build-in-place functions as the initialization of an allocator.
17394 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17395 handling calls to build-in-place functions in contexts that do not
17396 involve init of a separate object (for example, actuals of subprogram
17398 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17399 handling calls to build-in-place functions as the initialization of an
17400 object declaration.
17401 (Detect_Infinite_Recursion): Add explicit parameter Process to
17402 instantiation of Traverse_Body to avoid unreferenced warning.
17403 (Check_Overriding_Inherited_Interfaces): Removed.
17404 (Register_Interface_DT_Entry): Code cleanup.
17405 (Register_Predefined_DT_Entry): Code cleanup.
17406 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17407 inlined statements if within a transient scope.
17408 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17409 formal parameters with occurrences of actuals in inlined body, establish
17410 visibility on the proper view of the actual's subtype for the body's
17412 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17413 compatibility mode and we have an imported CPP subprogram because
17414 for now we assume that imported CPP primitives correspond with
17415 objects whose constructor is in the CPP side (and therefore we
17416 don't need to generate code to register them in the dispatch table).
17417 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17418 aligned selected component.
17419 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17420 the actual of an in-mode parameter is a type conversion.
17421 (Expand_Actuals): If the call does not come from source and the actual
17422 is potentially misaligned, let gigi handle it rather than rejecting the
17423 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17424 Class Wide types as returning by reference independantly of their
17425 controlled status since with HIE runtimes class wide types are not

17448 Pablo Oliveira <oliveira@adacore.com>
17450 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17451 subprogram Ids, even if they are not yet assigned.
17452 (Build_Subprogram_Id): It is now this function that will take care of
17453 calling Assign_Subprogram_Ids if necessary.
17454 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17455 should be done only once they are assigned.
17456 (Build_From_Any_Function, case of tagged types): Add missing call to
17458 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17459 type for an RACW type.
17460 (Add_RACW_Features): When processing an RACW declaration for which the
17461 designated type is already frozen, enforce E.2.2(14) rules immediately.
17462 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17463 special reordering of controlling formals.
17465 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17466 associated stub type for an RACW type.
17468 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17470 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17471 fixed-point operations in an integer context, i.e. as operands of a
17472 conversion to an integer type, indicate that result must be rounded.
17474 2006-10-31 Robert Dewar <dewar@adacore.com>
17476 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17477 cases, pass the encoding method, since it is now required by the run
17480 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17481 assumption that Str'First = 1.
17482 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17483 it on to the Value_Wide_Wide_Character call.
17484 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17485 properly handles a string of the form quote-encoded_wide_char-quote.
17487 * s-wchcnv.adb: Minor reformatting
17489 2006-10-31 Javier Miranda <miranda@adacore.com>
17491 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17492 run-time membership test to ensure that the constructed object
17493 implements the target abstract interface.
17495 2006-10-31 Robert Dewar <dewar@adacore.com>
17497 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17498 Machine_Attribute pragma internally to implement the user pragma.
17499 Add processing for pragma Interface so that it is now completely
17500 equivalent to pragma Import.
17502 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17503 so that it can be applied to all entities, including record components
17504 and enumeration literals.
17505 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17506 priority ranges are correct, verify compatibility against task
17507 dispatching and locking policies, and if everything is correct an entry
17508 is added to the table containing priority specific dispatching entries
17509 for this compilation unit.
17510 (Delay_Config_Pragma_Analyze): Delay processing
17511 Priority_Specific_Dispatching pragmas because when processing the
17512 pragma we need to access run-time data, such as the range of
17513 System.Any_Priority.
17514 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17515 Allow pragma Unreferenced as a context item
17516 Add pragma Preelaborable_Initialization
17517 (Analyze_Pragma, case Interface): Interface is extended so that it is
17518 now syntactically and semantically equivalent to Import.
17519 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17520 insertion characters.
17521 Add handling for Pragma_Wide_Character_Encoding
17522 (Process_Restrictions_Restriction_Warnings): Ensure that a warning

17532 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17533 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17534 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17536 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17537 type of the function containing a return statement, because the
17538 Return_Type field was removed. We now use the Return_Applies_To field.
17540 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17541 (Build_Task_Image_Decl): If procedure is not called from an
17542 initialization procedure, indicate that function that builds task name
17543 uses the sec. stack. Otherwise the enclosing initialization procedure
17544 will carry the indication.
17545 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17546 N_Object_Declaration instead.
17547 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17548 conditional dead code killed, and change implementation accordingly.
17549 (Insert_Actions): Add N_Return_Object_Declaration case.
17550 Correct comment to mention N_Extension_Aggregate node.
17551 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17552 attempts to save information for global variables which cannot be
17554 (Get_Current_Value_Condition): Handle conditions the other way round
17555 (constant on left). Also handle right operand of AND and AND THEN
17556 (Set_Current_Value_Condition): Corresponding changes
17557 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17558 (Get_Current_Value_Condition): Handle simple boolean operands
17559 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17560 (Get_Current_Value_Condition): If the variable reference is within an
17561 if-statement, does not appear in the list of then_statments, and does
17562 not come from source, treat it as being at unknown location.
17563 (Get_Current_Value_Condition): Enhance to allow while statements to be
17564 processed as well as if statements.
17565 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17567 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17568 of loop. This is safe now that we fixed Kill_Current_Values.
17569 (OK_To_Do_Constant_Replacement): Check whether current scope is
17570 Standard, before examining outer scopes.
17572 2006-10-31 Vincent Celier <celier@adacore.com>

17587 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17589 * g-expect.adb: Add Warnings (Off) to prevent new warning
17591 * lib-xref.adb: Add handling of Last_Assignment field
17592 (Generate_Reference): Centralize handling of pragma Obsolescent here
17593 (Generate_Reference): Accept an implicit reference generated for a
17594 default in an instance.
17595 (Generate_Reference): Accept a reference for a node that is not in the
17596 main unit, if it is the generic body corresponding to an subprogram
17599 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17601 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17603 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17605 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17606 use clauses, to avoid messages on packages used to qualify, and also
17607 to avoid messages from obsolescent units.
17608 (Warn_On_Useless_Assignments): Don't generate messages for imported
17609 and exported variables.
17610 (Warn_On_Useless_Assignments): New procedure
17611 (Output_Obsolescent_Entity_Warnings): New procedure
17612 (Check_Code_Statement): New procedure

17616 (Last_Assignment): New field for useless assignment warning
17618 2006-10-31 Olivier Hainque <hainque@adacore.com>
17620 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17621 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17623 2006-10-31 Bob Duff <duff@adacore.com>
17624 Robert Dewar <dewar@adacore.com>
17625 Ed Schonberg <schonberg@adacore.com>
17627 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17628 Ada 95 mode, because it violates the new rules for AI-318.
17630 * g-awk.ads: Use overloaded subprograms in every case where we used to
17631 have a default of Current_Session. This makes the code closer to be
17632 correct for both Ada 95 and 2005.
17634 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17635 code, relying on the fact that the compiler generates a warning
17636 instead of an error in -gnatg mode.
17638 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17639 E_Return_Statement entity kind.
17640 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17642 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17643 report an error if the reserved word abstract has been previously found.
17644 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17646 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17647 parenthesized range attribute usage
17648 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17650 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17651 in the syntax for extended_return_statement. This is not in the latest
17652 RM, but the ARG is expected to issue an AI allowing this.
17653 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17654 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17655 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17656 P_Return_Statement): Parse the new syntax for extended_return_statement.
17658 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17659 Output_End_Missing): Add error-recovery code for the new
17660 extended_return_statement syntax; that is, the new E_Return entry on
17663 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17664 limited to nonlimited, because otherwise we violate the new Ada 2005
17665 rules about returning limited types in function Create_AST_Handler in
17668 * sem.adb (Analyze): Add cases for new node kinds
17669 N_Extended_Return_Statement and N_Return_Object_Declaration.
17671 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17672 type is in the same category as type of context before applying check,
17673 to prevent anomalies in instantiations.
17674 (Resolve_Aggregate): Remove test for limited components in aggregates.
17675 It's unnecessary in Ada 95, because if it has limited components, then
17676 it must be limited. It's wrong in Ada 2005, because limited aggregates
17678 (Resolve_Record_Aggregate): Move check for limited types later, because
17679 OK_For_Limited_Init requires its argument to have been resolved.
17680 (Get_Value): When copying the component default expression for a
17681 defaulted association in an aggregate, use the sloc of the aggregate
17682 and not that of the original expression, to prevent spurious
17683 elaboration errors, when the expression includes function calls.
17684 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17685 were missing. We also didn't handle qualified expressions. Now also
17686 allow function calls. Use new common routine OK_For_Limited_Init.
17687 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17688 with space can upper case letter).
17690 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17691 Has_Static_Discriminants flag
17692 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17693 type with discriminants.
17694 (Process_Range_Expr_In_Decl): Do validity checks on range
17695 (Build_Discriminant_Constraints): Use updated form of
17696 Denotes_Discriminant.
17697 (Process_Subtype): If the subtype is a private subtype whose full view
17698 is a concurrent subtype, introduce an itype reference to prevent scope
17700 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17701 Record_Type_Declaration): The functionality of the subprograms
17702 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17703 is now performed by a single routine.
17704 (Build_Derived_Record_Type): If the type definition includes an explicit
17705 indication of limitedness, then the type must be marked as limited here
17706 to ensure that any access discriminants will not be treated as having
17707 a local anonymous access type.
17708 (Check_Abstract_Overriding): Issue a detailed error message when an
17709 abstract subprogram was not overridden due to incorrect mode of its
17711 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17712 synchronized private extension declarations. Verify that the ancestor is
17713 a limited or synchronized interface or in the generic case, the ancestor
17714 is a tagged limited type or synchronized interface and all progenitors
17715 are either limited or synchronized interfaces.
17716 Derived_Type_Declaration): Check for presence of private extension when
17717 dealing with synchronized formal derived types.
17718 Process_Full_View): Enchance the check done on the usage of "limited" by
17719 testing whether the private view is synchronized.
17720 Verify that a synchronized private view is completed by a protected or
17722 (OK_For_Limited_Init_In_05): New function.
17723 (Analyze_Object_Declaration): Move check for limited types later,
17724 because OK_For_Limited_Init requires its argument to have been resolved.
17725 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17726 in order to alleviate the upward compatibility introduced by AI-318.
17727 (Constrain_Corresponding_Record): If the constraint is for a component
17728 subtype, mark the itype as frozen, to avoid out-of-scope references to
17729 discriminants in the back-end.
17730 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17731 this subprogram against wrong sources.
17732 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17733 discriminant of limited type completed with a protected type, when the
17734 discriminant is used to constrain a private component of the type, and
17735 expansion is disabled.
17736 (Find_Type_Of_Object): Do not treat a return subtype that is an
17737 anonymous subtype as a local_anonymous_type, because its accessibility
17738 level is the return type of the enclosing function.
17739 (Check_Initialization): In -gnatg mode, turn the error "cannot
17740 initialize entities of limited type" into a warning.
17741 (OK_For_Limited_Init): Return true for generated nodes, since it
17742 sometimes violates the legality rules.
17743 (Make_Incomplete_Declaration): If the type for which an incomplete
17744 declaration is created happens to be the currently visible entity,
17745 preserve the homonym chain when removing it from visibility.
17746 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17747 inherited subprograms.
17748 (Access_Definition): If this is an access to function that is the return
17749 type of an access_to_function definition, context is a type declaration
17750 and the scope of the anonymous type is the current one.
17751 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17752 incomplete subtype to the set of private dependents of the original
17754 (Constrain_Discriminated_Type): Emit an error message whenever an
17755 incomplete subtype is being constrained.
17756 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17757 corresponding subtype of the full view of the original incomplete type.
17758 (Check_Incomplete): Properly detect invalid usage of incomplete types
17761 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
17763 * g-catiio.ads, g-catiio.adb (Value): New function.

17772 Robert Dewar <dewar@adacore.com>
17774 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
17775 handling executable extension manually and duplicating code.
17777 * make.adb: Implement new -S switch
17778 (Gnatmake): Use new function Osint.Executable_Name instead
17779 of handling executable extension manually.
17781 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
17782 is specified, the executable name ends with this suffix.
17783 Take advantage of Osint.Executable_Name instead of duplicating code.
17785 * switch-m.adb: Recognize new gnatmake -S switch
17787 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
17789 (Get_Target_Parameters): Set Executable_Extension_On_Target if
17792 * makeusg.adb: Add line for gnatmake -S switch
17794 2006-10-31 Vincent Celier <celier@adacore.com>
17796 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17797 call it with -static-libgcc, as there are some platforms, such as
17798 Darwin, where one of these two switches is compulsory to link.
17800 2006-10-31 Vincent Celier <celier@adacore.com>
17802 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17803 instead of ADA_PROJECT_PATH, for the project path.
17804 (Gnatls): When displaying the project path directories, use host dir
17807 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17808 names in the project path, as absolute paths may correspond to
17809 multi-valued VMS logical names.
17811 2006-10-31 Vincent Celier <celier@adacore.com>
17813 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
17814 absolute path name.
17815 (Locate_Regular_File): Ditto
17816 (Change_Dir): Remove, no longer used
17817 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
17818 on Windows. Get it calling Get_Current_Dir.
17819 (OpenVMS): Remove imported boolean, no longer needed.
17820 (Normalize_Pathname)[VMS]: Do not resolve directory names.
17821 (Pid_To_Integer): New function to convert a Process_Id to Integer
17823 2006-10-31 Thomas Quinot <quinot@adacore.com>
17825 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
17826 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
17828 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
17831 2006-10-31 Robert Dewar <dewar@adacore.com>
17833 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
17834 initial letter o as a zero.

17840 2006-10-31 Robert Dewar <dewar@adacore.com>
17842 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
17844 (Layout_Variant_Record): Retrieve the discriminants from the entity
17845 rather than from the type definition, because in the case of a full
17846 type for a private type we need to take the discriminants from the
17848 (Layout_Component_List): When applying the Max operator to variants with
17849 a nonstatic size, check whether either operand is static and scale that
17850 operand from bits to storage units before applying Max.
17851 (Layout_Type): In VMS, if a C-convention access type has no explicit
17852 size clause (and does not inherit one in the case of a derived type),
17853 then the size is reset to 32 from 64.
17855 2006-10-31 Vincent Celier <celier@adacore.com>
17857 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
17858 its file has already been loaded, according to the unit being loaded,
17859 not to the current value of Multiple_Unit_Index.
17861 2006-10-31 Thomas Quinot <quinot@adacore.com>
17862 Eric Botcazou <ebotcazou@adacore.com>

17869 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
17870 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
17871 a-calend-mingw.adb version.
17873 * Makefile.rtl: Added s-dsaser.
17874 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
17875 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
17876 Ada.Dispatching.Round_Robin.
17877 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
17879 * Make-lang.in: Remove all references to gt-ada-decl.h.
17880 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler

17890 (Initialize): Remove, no longer used
17891 (Ar): If Ar_Exec is null, get the location of the archive builder and,
17892 if there is one, the archive indexer. Fail if the archive builder cannot
17894 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
17897 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17899 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
17900 Process_Body_Clauses): If the context of a body includes a use clause
17901 for P.Q then a with_clause for P in the same body is not redundant,
17902 even if the spec also has a with_clause on P.
17903 Add missing continuation mark to error msg
17904 (Build_Limited_Views): A limited view of a type is tagged if its
17905 declaration includes a record extension.
17906 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
17907 node, even if the subunit has errors. This avoids malfunction by
17908 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
17909 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
17910 generation of obsolescent messages for with statements (cannot do
17911 this too early, or we cannot implement avoiding the messages in the
17912 case of obsolescent units withing obsolescent units).
17913 (Install_Siblings): If the with_clause is on a remote descendant of
17914 an ancestor of the current compilation unit, find whether there is
17915 a sibling child unit that is immediately visible.
17916 (Remove_Private_With_Clauses): New procedure, invoked after completing
17917 the analysis of the private part of a nested package, to remove from
17918 visibility the private with_clauses of the enclosing package
17920 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
17921 now centralized in Generate_Reference.
17922 (Install_Limited_Context_Clauses): Remove superfluous error
17923 message associated with unlimited view visible through use
17924 and renamings. In addition, at the point in which the error
17925 is reported, we add the backslash to the text of the error
17926 to ensure that it is reported as a single error message.
17927 Use new // insertion for some continuation messages
17928 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
17929 to create implicit with_clause for parent unit mentioned in original
17930 limited_with_clause.
17931 (Install_Limited_With_Unit): Set entity of parent identifiers if the
17932 unit is a child unit. For ASIS queries.
17933 (Analyze_Subunit): If the subunit appears within a child unit, make all
17934 ancestor child units directly visible again.

17944 (P_Formal_Type_Definition, P_Formal_Derived_Type_Definition): Add
17945 support for synchronized derived type definitions.
17946 Add the new actual Abstract_Present to every call to
17947 P_Interface_Type_Definition.
17948 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
17949 a formal object declaration with an access definition or a subtype mark
17950 with a null exclusion.
17951 (P_Generic_Association): Handle association with box, and others_choice
17952 with box, to support Ada 2005 partially parametrized formal packages.
17954 2006-10-31 Robert Dewar <dewar@adacore.com>
17955 Javier Miranda <miranda@adacore.com>
17957 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
17958 (P_Type_Declaration): Remove barrier against the reserved word "limited"
17959 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
17960 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
17961 private extensions.
17962 (P_Type_Declaration): Add the new actual Abstract_Present to every call
17963 to P_Interface_Type_Definition.
17964 (P_Interface_Type_Definition): Addition of one formal to report an error
17965 if the reserved word abstract has been previously found.
17966 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
17967 object renaming declaration with an access definition or subtype mark
17968 with a possible null exclusion.

17990 2006-10-31 Vincent Celier <celier@adacore.com>
17992 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
17993 on VMS, change "__" to '.' before checking the name.
17994 (Record_Ada_Source): Always add the source file name in the list of
17995 of sources, even if it is not the first time, as it is for another
17997 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
17998 dot, instead of replacing only the first '_'.
18000 * prj-part.adb (Parse): Convert project file path to canonical form
18002 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18003 extended, the project id of the project extending it is recorded in its
18004 data, even when it has already been processed as an imported project.
18006 2006-10-31 Robert Dewar <dewar@adacore.com>
18008 * repinfo.adb (List_Entities): Don't list entities from renaming
18011 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18012 Robert Dewar <dewar@adacore.com>
18014 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18015 only a restriction warning is active for the given restriction. This is
18016 desirable because we do not want to modify code in the case where only
18018 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18019 causes overriding of real restrictions.
18020 Take advantage of new No_Restrictions constant.
18022 * raise.h: (__gnat_set_globals): Change profile.
18024 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18026 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18029 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18030 Move all the entities in obsolete package System.PolyORB_Interface to
18031 System.Partition_Interface.
18032 (RE_Storage_Size): New function in System.Tasking.

18049 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18050 properly an attempt to apply Unchecked_Access to a protected operation.
18051 (OK_Self_Reference): New subprogram to check the legality of an access
18052 attribute whose prefix is the type of an enclosing aggregate.
18053 Generalizes previous mechanism to handle attribute references nested
18054 arbitrarily deep within the aggregate.
18055 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18056 can appear in an aggregate if this is a default-initialized aggregate
18057 for a self-referential type.
18058 (Resolve_Attribute, case Access): Ditto.
18059 Add support for new implementation defined attribute Stub_Type.
18060 (Eval_Attribute, case Attribute_Stub_Type): New case.
18061 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18062 (Stream_Attribute_Available): Implement using new subprogram from
18063 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18064 Has_Specified_Stream_Attribute flag.
18065 Disallow Storage_Size and Storage_Pool for access to subprogram
18066 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18067 access types of return subtypes in extended return statements. Remove
18068 accessibility checks on anonymous access types when Unchecked_Access is
18070 (Analyze_Attribute): Add support for the use of 'Class to convert
18071 a class-wide interface to a tagged type.
18072 Add support for the attribute Priority.
18073 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18074 whether the designated type is discriminated with a constrained partial
18075 view and require static matching in that case.
18076 Add local variable Des_Btyp. The Designated_Type
18077 of an access to incomplete subtype is either its non-limited view if
18078 coming from a limited with or its etype if regular incomplete subtype.
18080 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18081 Fix predicate to identify and allow cases of (expander-generated)
18082 references to tag of designated object of a RACW.
18083 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18084 non-static, and therefore cannot appear as a primary in a preelaborable
18086 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18087 Has_Read_Write_Attributes.
18088 (Has_Read_Write_Attributes): Reimplement in termes of
18089 Has_Stream_Attribute_Definition.
18090 (Missing_Read_Write_Attributes): When checking component types in a
18091 record, unconditionally call Missing_Read_Write_Attributes recursively
18092 (remove guard checking for Is_Record_Type / Is_Access_Type).
18094 2006-10-31 Robert Dewar <dewar@adacore.com>
18096 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18097 useless assignments here and conditionalize it on absence of exception
18099 (Analyze_Exception_Handlers): Small code reorganization of error
18100 detection code, for new handling of formal packages.
18102 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18103 Hristian Kirtchev <kirtchev@adacore.com>
18105 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18106 that has been constant-folded, preserve information of original tree,
18108 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18109 generated private extension declaration if the formal derived type is
18110 synchronized. Carry synchronized present over to the generated private
18112 (Validate_Derived_Type_Instance): Ensure that the actual of a
18113 synchronized formal derived type is a synchronized tagged type.
18114 (Instantiate_Formal_Package): When creating the instantiation used to
18115 validate the actual package of a formal declared without a box, check
18116 whether the formal itself depends on a prior actual.
18117 (Instantiate_Formal_Subprogram): Create new entities for the defining
18118 identifiers of the formals in the renaming declaration, for ASIS use.
18119 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18120 a renaming declaration or a subtype declaration for an actual in an
18121 instance, capture location information of declaration in generic, for
18123 (Instantiate_Formal_Package): Add comments on needed additional tests.
18124 AI-317 (partial parametrization) is fully implemented.
18125 (Validate_Private_Type_Instance): Add check for actual which
18126 must have preelaborable initialization
18127 Use new // insertion for some continuation messages
18128 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18129 Default_Expression. Add type retrieval when the declaration has an
18130 access definition. Update premature usage of incomplete type check.
18131 (Check_Access_Definition): New subsidiary routine. Check whether the
18132 current compilation version is Ada 05 and the supplied node has an
18134 (Instantiate object): Alphabetize local variables. Handle the creation
18135 of new renaming declarations with respect to the kind of definition
18136 used - either an access definition or a subtype mark. Guard against
18137 unnecessary error message in the context of anonymous access types after
18138 they have been resolved. Add check for required null exclusion in a
18139 formal object declaration.
18140 (Switch_View): A private subtype of a non-private type needs to be
18141 switched (the base type can have been switched without its private
18142 dependents because of the last branch of Check_Private_View.
18143 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18145 (Instantiate_Type): Emit an error message whenever a class-wide type of
18146 a tagged incomplete type is used as a generic actual.
18147 (Find_Actual_Type): Extend routine to handle a component type in a child
18148 unit that is imported from a formal package in a parent.
18149 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18150 agree on constrainedness, rather than checking against ultimate ancestor
18151 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18152 generic body, for navigation purposes.

18155 Thomas Quinot <quinot@adacore.com>
18157 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18159 (New_Stream_Subprogram): When processing an attribute definition clause
18160 for a stream-oriented subprogram, record an entity node occurring at
18161 the point of clause to use for checking the visibility of the clause,
18162 as defined by 8.3(23) as amended by AI-195.
18163 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18164 New_Stream_Function and New_Stream_Procedure.
18165 (New_Stream_Function, New_Stream_Procedure): Removed.
18166 (Analyze_Attribute_Definition_Clause, case Address): Check new
18167 Alignment_Check check

18170 Javier Miranda <miranda@adacore.com>
18171 Robert Dewar <dewar@adacore.com>
18173 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18174 generate the same errors compiling under -gnatc.
18175 (Try_Object_Operation): If no candidate interpretation succeeds, but
18176 there is at least one primitive operation with the right name, report
18177 error in call rather than on a malformed selected component.
18178 (Analyze_Selected_Component): If the prefix is an incomplete type from
18179 a limited view, and the full view is available, use the full view to
18180 determine whether this is a prefixed call to a primitive operation.
18181 (Operator_Check): Verify that a candidate interpretation is a binary
18182 operation before checking the type of its second formal.
18183 (Analyze_Call): Add additional warnings for function call contexts not
18185 (Analyze_Allocator): Move the check for "initialization not allowed for
18186 limited types" after analyzing the expression. This is necessary,
18187 because OK_For_Limited_Init looks at the structure of the expression.
18188 Before analysis, we don't necessarily know what sort of expression it
18189 is. For example, we don't know whether F(X) is a function call or an
18190 indexed component; the former is legal in Ada 2005; the latter is not.
18191 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18192 were missing. We also didn't handle qualified expressions. Now also
18193 allow function calls. Use new common routine OK_For_Limited_Init.
18194 (Analyze_Type_Conversion): Do not perform some legality checks in an
18195 instance, because the error message will be redundant or spurious.
18196 (Analyze_Overloaded_Selected_Component): Do not do style check when
18197 setting an entity, since we do not know it is the right entity yet.
18198 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18199 (Analyze_Overloaded_Selected_Component): Same change
18200 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18201 since regular incomplete subtypes are transformed into corresponding
18202 subtypes of their full views.
18203 (Complete_Object_Operation): Treat name of transformed subprogram call
18204 as coming from source, for browsing purposes.
18205 (Try_Primitive_Operation): If formal is an access parameter, compare
18206 with base type of object to determine whether it is a primitive
18208 (Operator_Check): If no interpretation of the operator matches, check
18209 whether a use clause on any candidate might make the operation legal.
18210 (Try_Class_Wide_Operation): Check whether the first parameter is an
18211 access type whose designated type is class-wide.

18218 warn on infinite loops.
18219 Add \\ to some continuation messages
18220 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18221 (Process_Bounds): If the bounds are integer literals that result from
18222 constant-folding, and they carry a user-defined type, preserve that type
18223 rather than treating this as an integer range.
18224 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18225 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18226 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18227 left hand side of assignment.
18228 (Analyze_Assignment): Add suport to manage assigments to the attribute
18229 priority of a protected object.
18230 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18231 not just identifiers.
18232 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18233 or AND THEN for possible tracking.
18234 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18235 case of while loops so we can track values in the loop body.

18238 Hristian Kirtchev <kirtchev@adacore.com>
18239 Bob Duff <duff@adacore.com>
18241 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18242 procedure cannot be a protected operation (it is a basic_declaration,
18243 not a subprogram_declaration).
18244 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18245 Subp. Add logic for entry processing.
18246 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18247 Determine whether an entry or subprogram of a protected or task type
18248 override an inherited primitive of an implemented interface.
18249 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18250 Update the actual used in calls to Check_Overriding_Indicator.
18251 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18252 generate the proper reference to the parent unit, for cross-reference.
18253 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18255 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18256 (Add_Extra_Formal): Revise procedure to allow passing in associated
18257 entity, scope, and name suffix, and handle setting of the new
18258 Extra_Formals field.
18259 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18260 pass new parameters. Add support for adding the new extra access formal
18261 for functions whose calls are treated as build-in-place.
18262 (Analyze_A_Return_Statement): Correct casing in error message.
18263 Move Pop_Scope to after Analyze_Function_Return, because an extended
18264 return statement really is a full-fledged scope. Otherwise, visibility
18265 doesn't work right. Correct use of "\" for continuation messages.
18266 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18267 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18268 the node doesn't get properly marked as analyzed.
18269 (Analyze_Subprogram_Body): If subprogram is a function that returns
18270 an anonymous access type that denotes a task, build a Master Entity
18272 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18273 proper usage of null exclusion in a result definition.
18274 (Process_Formals): Code cleanup and new error message.
18275 (Process_Formals): Detect incorrect application of null exclusion to
18277 (Conforming_Types): Handle conformance between [sub]types and itypes
18278 generated for entities that have null exclusions applied to them.
18279 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18280 base type is an access subtype. This case arrises with null exclusions.
18281 (New_Overloaded_Entity): Do not remove the overriden entity from the
18282 homonym chain if it corresponds with an abstract interface primitive.
18283 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18284 call to the synthesized predicate Is_Incomplete_Type.
18285 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18287 (Analyze_Subprogram_Declaration): Check that abstract interface
18288 primitives are abstract or null.
18289 (Analyze_Subprogram_Specification): Remove previous check for abstract
18290 interfaces because it was not complete.
18291 (Has_Interface_Formals): Removed.

18294 Javier Miranda <miranda@adacore.com>
18296 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18297 of Analyze_Package_Body, to create Itype references for anonymous
18298 access types created in the package declaration, whose designated types
18299 may have only a limited view.
18300 (Analyze_Package_Specification): For the private part of a nested
18301 package, install private_with_clauses of enclosing compilation unit if
18302 we are in its visible part.
18303 (Declare_Inherited_Private_Subprograms): Complete barrier
18304 to ensure that the primitive operation has an alias to some parent
18305 primitive. This is now required because, after the changes done for the
18306 implementation of abstract interfaces, the contents of the list of
18307 primitives has entities whose alias attribute references entities of
18308 such list of primitives.
18309 (Analyze_Package_Specification): Simplify code that handles parent units
18310 of instances and formal packages.
18311 (Uninstall_Declarations): Check the convention consistency among
18312 primitive overriding operations of a tagged record type.

18321 expected and found set right)
18322 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18323 (Analyze_Generic_Renaming): Same fix
18324 (Use_One_Package): Do not take into account the internal entities of
18325 abstract interfaces during the analysis of entities that are marked
18326 as potentially use-visible.
18327 (Find_Type): Handle the case of an attribute reference for
18328 implementation defined attribute Stub_Type (simply let the analysis of
18329 the attribute reference rewrite it).
18330 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18331 type that appears in a Use_Type clause.
18332 (Analyze_Object_Renaming): Add support for renaming of the Priority
18334 (Find_Type): In Ada 2005, a task type can be used within its own body,
18335 when it appears in an access definition.
18336 (Analyze_Object_Renaming): Remove warning on null_exclusion.

19552 other basic tools. The full version that includes the Ada 2005 stuff

19554 not want to cause bootstrap problems with compilers not recognizing

19850 Thomas Quinot <quinot@adacore.com>
19852 * checks.adb (Build_Discriminant_Checks): If the expression being
19853 checks is an aggregate retrieve the values of its discriminants to
19854 generate the check, rather than creating a temporary and a reference

19876 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
19877 Remove 0-9 as debug flag character possibilities
19878 -d is now controlling the primary stack size when its value is a
19879 positive. Also add checks against invalid values, and support for kb,
19880 mb. Ditto for -D switch.

19883 Serguei Rybin <rybin@adacore.com>
19885 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
19886 save/restore routines.
19887 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19888 were not always properly handled previously.
19889 Since we are changing the tree format anyway, also get rid of the
19890 junk obsolete Immediate_Errors flag.
19891 (Tree_Read): Change the way of reading Tree_Version_String - now we
19892 read the version string from the tree even if its length is not the
19893 same as the length of the version string computed from Gnatvsn.
19894 (Search_Directory_Present): New Boolean flag for the compiler.
19895 Define Tree_Version_String as a dynamic string.

19910 Ed Schonberg <schonberg@adacore.com>
19912 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
19913 against errors in the source program: a private types for which the
19914 corresponding full type declaration is missing and pragma CPP_Virtual
19916 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
19917 (Is_Known_Null): New flag
19918 (Has_Pragma_Pure): New flag

19920 (Is_Limited_Type): A type whose ancestor is an interface is limited if
19921 explicitly declared limited.
19922 (DT_Offset_To_Top_Func): New attribute that is present in E_Component

19925 whose ancestor has discriminants.
19927 * exp_ch2.adb: Update status of new Is_Known_Null flag
19929 * sem_ch7.adb: Maintain status of new Is_Known_Null flag

19943 (__gnat_handle_vms_condition): Adjust context before raise.
19944 (__gnat_install_handler): Restore the global vector setup for GCC
19945 versions before 3.4, as the frame based circtuitry is not available

19948 (__gl_default_stack_size): new variable.
19950 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19952 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
19953 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
19954 does not exist in the Ada RM.
19955 (Compatible_Int_Bounds): Determine whether two integer range bounds
19956 are of equal length and have the same start and end values.
19957 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
19958 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
19959 aggregate when it is part of an object declaration.
19960 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
19961 constrains discriminants of its parent, add explicitly the discriminant
19962 constraints of the ancestor by retrieving them from the
19963 stored_constraint of the parent.
19965 2006-02-13 Robert Dewar <dewar@adacore.com>
19967 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
19968 attribute Mechanism_Code is applied to renamed subprogram, modify
19969 prefix to point to base subprogram.
19970 Max/Min attributes now violate Restriction No_Implicit_Conditionals
19972 * sinfo.ads: Document that Mechanism_Code cannot be applied to
19973 renamed subprograms so that the front-end must replace the prefix
19976 2006-02-13 Javier Miranda <miranda@adacore.com>
19977 Gary Dismukes <dismukes@adacore.com>
19979 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
19980 availability of RE_Interface_Tag.
19981 (Build_Initialization_Call): Fix wrong access to the discriminant value.
19982 (Freeze_Record_Type): Do not generate the tables associated with
19983 timed and conditional dispatching calls through synchronized
19984 interfaces if compiling under No_Dispatching_Calls restriction.
19985 When compiling for Ada 2005, for a nonabstract
19986 type with a null extension, call Make_Controlling_Function_Wrappers
19987 and insert the wrapper function declarations and bodies (the latter
19988 being appended as freeze actions).
19989 (Predefined_Primitive_Bodies): Do not generate the bodies of the
19990 predefined primitives associated with timed and conditional
19991 dispatching calls through synchronized interfaces if we are
19992 compiling under No_Dispatching_Calls.
19993 (Build_Init_Procedure): Use RTE_Available to check if a run-time
19994 service is available before generating a call.
19995 (Make_Controlling_Function_Wrappers): New procedure.
19996 (Expand_N_Full_Type_Declaration): Create a class-wide master for
19997 access-to-limited-interfaces because they can be used to reference
19998 tasks that implement such limited interface.
19999 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20000 procedure spec and body of the Offset_To_Top function that is generated
20001 when the parent of a type with discriminants has secondary dispatch
20003 (Init_Secondary_Tags): Handle the case in which the parent of the type
20004 containing secondary dispatch tables has discriminants to generate the
20005 correct arguments to call Set_Offset_To_Top.
20006 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20008 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20009 Add Wide_[Wide_]Expanded_Name.
20010 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20011 the same functionality of Get_Prim_Op_Address but applied to predefined
20012 primitive operations because the pointers to the predefined primitives
20013 are now saved in a separate table.
20014 (Parent_Size): Modified to get access to the separate table of primitive
20015 operations or the parent type.
20016 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20017 functionality of Set_Prim_Op_Address but applied to predefined primitive
20019 (Set_Signature): New subprogram used to store the signature of a DT.
20020 (Displace): If the Offset_To_Top value is not static then call the
20021 function generated by the expander to get such value; otherwise use
20022 the value stored in the table of interfaces.
20023 (Offset_To_Top): The type of the actual has been changed to Address to
20024 give the correct support to tagged types with discriminants. In this
20025 case this value is stored just immediately after the tag field.
20026 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20027 offset_to_top value is static and hence pass this value to the run-time
20028 to store it in the table of interfaces, or else if this value is dynamic
20029 and then pass to the run-time the address of a function that is
20030 generated by the expander to provide this value for each object of the
20033 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20034 (Default_Prim_Op_Count): New entity
20035 (Get_Predefined_Prim_Op_Address): New entity

20040 Ed Schonberg <schonberg@adacore.com>
20042 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20043 Make_Adjust_Call done for a newly-allocated object.
20045 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20046 in a subprogram are wrapped in a cleanup block, indicate that the
20047 subprogram contains an inner block with an exception handler.
20048 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20049 Adjust call is for a newly-allocated object. In that case we must not
20050 assume that the finalization list chain pointers are correct (since they
20051 come from a bit-for-bit copy of the original object's pointers) so if
20052 the attach level would otherwise be zero (no change), we set it to 4
20053 instead to cause the pointers to be reset to null.
20055 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20056 reset chain pointers to null.
20058 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20060 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20061 string, and the context requires a loop for the assignment (e.g.
20062 because the left-hand side is packed), generate a unique name for the
20063 temporary that holds the string, to prevent spurious name clashes.
20065 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20066 Javier Miranda <miranda@adacore.com>
20067 Robert Dewar <dewar@adacore.com>
20068 Gary Dismukes <dismukes@adacore.com>
20070 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20071 return unconstrained arrays.
20073 (Expand_Call): An indirect call through an access parameter of a
20074 protected operation is not a protected call.
20075 Add circuit to raise CE in Ada 2005 mode following call
20076 to Raise_Exception.
20077 (Register_DT_Entry): Do nothing if
20078 the run-time does not give support to abstract interfaces.
20079 (Freeze_Subprogram): In case of dispatching operations, do not generate
20080 code to register the operation in the dispatch table if the source
20081 is compiled with No_Dispatching_Calls.
20082 (Register_Predefined_DT_Entry): Generate code that calls the new
20083 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20084 Set_Prim_Op_Address.
20086 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20087 on array assignments if the right-hand side is a function call that has
20088 been inlined. Check is performed on the assignment in the block.
20089 (Process_Bounds): If bounds and range are overloaded, apply preference
20090 rule for root operations to disambiguate, and diagnose true ambiguity.
20091 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20092 a tag-indeterminate right-hand side even when Expander_Active is True.
20093 Needed to ensure that dispatching calls to T'Input are allowed and
20094 get the tag of the target class-wide object.
20096 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20097 an inherited primitive operation that already overrides several
20098 abstract interface primitives. For transitivity, the new entity must
20099 also override all the abstract interface primitives covered by the
20100 inherited overriden primitive.
20101 Emit warning if new entity differs from homograph in same scope only in
20102 that one has an access parameter and the other one has a parameter of
20103 a general access type with the same designated type, at the same
20104 position in the signature.
20105 (Make_Inequality_Operator): Use source locations of parameters and
20106 subtype marks from corresponding equality operator when creating the
20107 tree structure for the implicit declaration of "/=". This does not
20108 change anything in behaviour except that the decoration of the
20109 components of the subtree created for "/=" allows ASIS to get the
20110 string images of the corresponding identifiers.
20111 (Analyze_Return_Statement): Remove '!' in warning message.
20112 (Check_Statement_Sequence): Likewise.
20113 (Analyze_Subprogram_Body): For an access parameter whose designated type
20114 is an incomplete type imported through a limited_with clause, use the
20115 type of the corresponding formal in the body.
20116 (Check_Returns): Implicit return in No_Return procedure now raises
20117 Program_Error with a compile time warning, instead of beging illegal.
20118 (Has_Single_Return): Function returning unconstrained type cannot be
20119 inlined if expression in unique return statement is not an identifier.
20120 (Build_Body_To_Inline): It is possible to inline a function call that
20121 returns an unconstrained type if all return statements in the function
20122 return the same local variable. Subsidiary procedure Has_Single_Return
20123 verifies that the body conforms to this restriction.
20125 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20126 same type, and one of them is of an anonymous access type, convert
20127 the other operand to it, so that this is a valid binary operation for
20129 (Resolve_Type_Conversion): Handle subtypes of protected types and
20130 task types when accessing to the corresponding record type.
20131 (Resolve_Allocator): Add '\' in 2-line warning message.
20132 Remove '!' in warning message.
20133 (Resolve_Call): Add '\' in 2-line warning message.
20134 (Valid_Conversion): Likewise.
20135 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20136 resulting type may be an access type with an implicit dereference.
20137 Obtain the proper component from the designated type.
20138 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20139 given by an expanded name with prefix Standard, when the operands are
20140 of an anonymous access type.
20141 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20142 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20143 prefix of the expression is not of an incomplete type. Allows full
20144 diagnoses of all semantic errors.
20145 (Resolve_Actuals): If the actual is an allocator whose directly
20146 designated type is a class-wide interface we build an anonymous
20147 access type to use it as the type of the allocator. Later, when
20148 the subprogram call is expanded, if the interface has a secondary
20149 dispatch table the expander will add a type conversion to force
20150 the displacement of the pointer.
20151 (Resolve_Call): If a function that returns an unconstrained type is
20152 marked Inlined_Always and inlined, the call will be inlined and does
20153 not require the creation of a transient scope.
20154 (Check_Direct_Boolean_Op): Removed
20155 (Resolve_Comparison_Op): Remove call to above
20156 (Resolve_Equality_Op): Remove call to above
20157 (Resolve_Logical_Op): Inline above, since this is only call.
20158 (Valid_Conversion): Handle properly conversions between arrays of
20159 convertible anonymous access types.
20162 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20163 the literal in an unchecked conversion, because GCC 4.x needs a static
20164 value for a string bound.
20166 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20167 Hristian Kirtchev <kirtchev@adacore.com>
20169 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20170 components of the corresponding record, take into account component
20171 definitions that are access definitions.
20172 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20173 procedure is not considered a dispatching call and will be expanded
20176 2006-02-13 Javier Miranda <miranda@adacore.com>
20178 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20179 controlling argument of the dispatching call is an abstract interface
20180 class-wide type then we use it directly.
20181 Check No_Dispatching_Calls restriction.
20182 (Default_Prim_Op_Position): Remove the code that looks for the last
20183 entity in the list of aliased subprograms. This code was wrong in
20185 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20186 when the source is compiled with the No_Dispatching_Calls restriction.
20187 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20188 if we are compiling with restriction No_Dispatching_Calls.
20189 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20190 subprograms if we are compiling under No_Dispatching_Calls restriction.
20191 (Make_DT): Generate a dispatch table with a single dummy entry if
20192 we are compiling with the No_Dispatching_Calls restriction. In
20193 addition, in this case we don't generate code that calls to the
20194 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20195 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20196 of this subprogram if compiling with the No_Dispatching_Calls
20198 (Expand_Type_Conversion): Instead of using the actual parameter,
20199 the argument passed as parameter to the conversion function was
20200 erroneously referenced by the expander.
20201 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20202 Set_Predefined_Primitive_Op_Address and Set_Signature.
20203 (Expand_Dispatching_Call): Generate call to
20204 Get_Predefined_Prim_Op_Address for predefined primitives.
20205 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20206 predefined primitives.
20207 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20208 primitives we reserve one dummy entry to ensure that the tag does not
20209 point to some memory that is associated with some other object. In
20210 addition, remove all the old code that generated the assignments
20211 associated with the signature of the dispatch table and replace them
20212 by a call to the new subprogram Set_Signature.
20213 (Set_All_DT_Position): Change the algorithm because now we have a
20214 separate dispatch table associated with predefined primitive operations.
20215 (Expand_Interface_Conversion): In case of non-static offset_to_top
20216 add explicit dereference to get access to the object after the call
20217 to displace the pointer to the object.
20218 (Expand_Interface_Thunk): Modify the generation of the actual used
20219 in the calls to the run-time function Offset_To_Top to fulfil its
20221 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20223 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20225 * exp_dist.adb (Copy_Specification): For access parameters, copy
20226 Null_Exclusion flag, which will have been set for stream subprograms
20229 2006-02-13 Pascal Obry <obry@adacore.com>
20231 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20232 previous implementation was using the C runtime spawnve routine but
20233 the corresponding wait was using directly the Win32 API. This was
20234 causing some times a lock when waiting for an event using
20235 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20236 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20237 API fixes this problem.
20239 2006-02-13 Robert Dewar <dewar@adacore.com>

20260 searching for the predefined equality operator, verify that operands
20261 have the same type.
20262 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20263 for the last entity in the list of aliased subprograms. This code
20264 was wrong in case of renamings.
20265 (Set_Renamed_Subprogram): New procedure
20266 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20267 Exp_Type constant computed when entering this subprogram.

20272 side effect, unlike other attributes that are functions. (from code
20274 (Remove_Side_Effects): Expressions that involve packed arrays or records
20275 are copied at the point of reference, and therefore must be marked as
20276 renamings of objects.

20278 not a dispatching operation.
20281 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20282 elementary types in all cases.

20287 task types when accessing to the corresponding record type.
20288 Remove '!' in warning message.
20290 2006-02-13 Olivier Hainque <hainque@adacore.com>
20292 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20293 to avoid useless and space inefficient overalignments on targets where
20294 Max_Alignment is larger than 16.
20296 2006-02-13 Pascal Obry <obry@adacore.com>
20298 * g-catiio.adb (Sec_Number): New type used to compute the number of
20299 seconds since 1-1-1970.
20300 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20301 negative numbers (years, months...) it is better to have a Natural here.
20303 (Image) [Number]: Change parameter from Long_Integer to Number.
20304 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20305 overflow for dates past year 2038.
20307 2006-02-13 Matthew Heaney <heaney@adacore.com>
20309 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise

20314 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20316 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20317 finalization can occur normally.
20319 2006-02-13 Vincent Celier <celier@adacore.com>
20321 * gnatcmd.adb (Rules_Switches): New table
20322 (Add_To_Rules_Switches): New procedure
20323 (GNATCmd): For command CHECK, put all options following "-rules" in the
20324 Rules_Switches table. Append these -rules switches after the -cargs
20327 2006-02-13 Robert Dewar <dewar@adacore.com>
20329 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20330 These two cases were generating incorrect output, and if this unit
20331 was built with checks on, generated a discriminant mismatch constraint
20334 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20335 Robert Dewar <dewar@adacore.com>
20337 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20338 view is an array type, indicate the component type as well, for
20339 navigation purposes.
20340 (Generate_Reference): Don't consider array ref on LHS to be a case
20341 of violating pragma Unreferenced.
20342 Do not give Ada 2005 warning except on real reference.
20344 2006-02-13 Vincent Celier <celier@adacore.com>
20346 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20347 main source, add switch -mdebug-main=_ada_ so that the executable can
20348 be debugged by the standard VMS debugger.
20349 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20350 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20351 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20352 of the last source, as the binding and linking phases are never
20354 Set all executable obsolete when rebuilding a library.
20356 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20359 2006-02-13 Javier Miranda <miranda@adacore.com>
20362 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20363 code to improve the error message reported when the program has
20364 declarations of abstract interface types and it is not compiled with
20365 the -gnat05 switch.
20366 (P_Access_Definition): Reorganize the code to improve the error
20367 message reported when the new Ada 2005 syntax for anonymous
20368 access types is used and the program is not compiled with the

20391 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20392 unknown, use the location of the project to report the error.
20393 (When_No_Sources): New global variable
20394 (Report_No_Ada_Sources): New procedure
20395 (Check): New parameter When_No_Sources. Set value of global variable
20397 (Find_Sources): Call Report_No_Ada_Sources when appropriate
20398 (Get_Sources_From_File): Ditto
20399 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20402 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20403 Call Prj.Proc.Process with parameter When_No_Sources.
20405 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20406 Call Recursive_Check with parameter When_No_Sources.
20407 (Recursive_Check): New parameter When_No_Sources. Call itself and
20408 Prj.Nmsc.Check with parameter When_No_Sources.
20409 (Process): New parameter When_No_Sources. Call Check with parameter
20411 (Copy_Package_Declarations): New procedure to copy renamed parameters
20412 and setting the location of the declared attributes to the location
20413 of the renamed package.

20421 When removing nodes (attributes Source_Dirs, Source_Files,
20422 Source_List_File and package Naming), save the comments and attach the
20423 saved comments to the newly created nodes.
20424 Do not add a with clause for the naming package if one already exists.

20433 aliased entities to look for the overriden abstract interface
20435 (Is_Interface_Subprogram): Complete documentation.
20436 (Check_Dispatching_Operation): Do not generate code to register the
20437 operation in the dispatch table if the source is compiled with
20438 restriction No_Dispatching_Calls.

20440 No_Return procedure with procedure that is not No_Return
20441 (Check_Dispatching_Call): Suppress the check for an abstract operation
20442 when the original node of an actual is a tag-indeterminate attribute
20443 call, since the attribute, which must be 'Input, can never be abstract.
20444 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20445 call to the Input attribute (even when rewritten).
20446 (Propagate_Tag): Augment comment to indicate the possibility of a call
20447 to an Input attribute.
20449 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20450 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.

20459 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20461 2006-02-13 Javier Miranda <miranda@adacore.com>
20463 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20464 handles default-initialized components to keep separate the management
20465 of this feature but also avoid the unrequired resolution and
20466 expansion of components that do not have partially initialized
20468 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20469 (Check_Bounds): Likewise.
20470 (Check_Length): Likewise.
20472 2006-02-13 Javier Miranda <miranda@adacore.com>
20473 Ed Schonberg <schonberg@adacore.com>
20475 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20476 abstract interface type call analyze_and_resolve to expand the type
20477 conversion into the corresponding displacement of the
20478 reference to the base of the object.
20479 (Eval_Attribute, case Width): For systems where IEEE extended precision
20480 is supported, the maximum exponent occupies 4 decimal digits.
20481 (Accessibility_Message): Add '\' in 2-line warning message.
20482 (Resolve_Attribute): Likewise.
20483 (case Attribute_Access): Significantly revise checks
20484 for illegal access-to-subprogram Access attributes to properly enforce
20485 the rules of 3.10.2(32/2).
20486 Diagnose use of current instance with an illegal attribute.
20488 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20490 (Enclosing_Generic_Unit): New function to return a node's innermost
20491 enclosing generic declaration node.
20492 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20493 (Type_Access_Level): The accessibility level of anonymous acccess types
20494 associated with discriminants is that of the current instance of the
20495 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20496 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20497 (Kill_Current_Values_For_Entity): New function
20498 (Enter_Name): Change formal type to Entity_Id
20500 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20501 Ed Schonberg <schonberg@adacore.com>
20502 Gary Dismukes <dismukes@adacore.com>
20504 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20505 Analyze_Compilation_Unit.
20506 Detect and warn on redundant with clauses detected in a package spec
20507 and/or body when -gnatwr is used.
20508 (Analyze_Context): Analyze config pragmas before other items
20509 (Install_Context_Items): Don't analyze config pragmas here
20510 (Install_Limited_Withed_Unit): Set limited entity of package in
20511 with_clause so that cross-reference information or warning messages on
20512 unused packages can be properly generated
20513 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20514 has Error_Posted set. Prevent infinite loops in illegal programs.
20515 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20516 to the point of the error test requiring the current unit to be private.
20517 This ensures that private with clauses are not exempted from the basic
20518 checking for being a descendant of the same library unit parent as a
20519 withed private descendant unit.
20520 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20521 handle private with clauses properly, as well as to account for cases
20522 where the withed unit is a public descendant of a private ancestor
20523 (in which case the current unit must be a descendant of the private
20524 ancestor's parent). The spec comments were updated accordingly. Also,
20525 the old error message in this subprogram was replaced with error
20526 messages that mirror the errors tested and reported by
20527 Check_Private_Child_Unit.
20528 Parameter and variable names improved for readability.
20529 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20530 private as the precondition for calling
20531 Check_Private_Limited_Withed_Unit since that subprogram has been
20532 revised to test public units as well as private units.

20537 Javier Miranda <miranda@adacore.com>
20539 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20540 that Scope_Stack.First = 1.
20541 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20542 were not always properly handled previously.
20543 (Formal_Entity): Complete rewrite, to handle properly some complex case
20544 with multiple levels of parametrization by formal packages.
20545 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20546 to the corresponding derived type declaration for proper semantics.
20548 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20549 (Check_Component): Enforce restriction on components of
20550 unchecked_unions: a component in a variant cannot contain tasks or
20552 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20554 Add pragma Ada_2005 (synonym for Ada_05)
20555 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20556 were not always properly handled previously.
20557 Document that pragma Propagate_Exceptions has no effect
20558 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20559 (Set_Convention_From_Pragma): Check that if a convention is
20560 specified for a dispatching operation, then it must be
20561 consistent with the existing convention for the operation.
20562 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20563 longer required to specify an vtable-ptr component in the record. For
20564 compatibility reasons we leave the support for the previous definition.
20565 (Analyze_Pragma, case No_Return): Allow multiple arguments
20567 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20568 non-overrideen inherited operation with a controlling result as
20569 illegal only its implicit declaration comes from the derived type
20570 declaration of its result's type.
20571 (Check_Possible_Deferred_Completion): Relocate the object definition
20572 node of the subtype indication of a deferred constant completion rather
20573 than directly analyzing it. The analysis of the generated subtype will
20574 correctly decorate the GNAT tree.
20575 (Record_Type_Declaration): Check whether this is a declaration for a
20576 limited derived record before analyzing components.
20577 (Analyze_Component_Declaration): Diagnose record types not explicitly
20578 declared limited when a component has a limited type.
20579 (Build_Derived_Record_Type): Code reorganization to check if some of
20580 the inherited subprograms of a tagged type cover interface primitives.
20581 This check was missing in case of a full-type associated with a private
20583 (Constant_Redeclaration): Check that the subtypes of the partial and the
20584 full view of a constrained deferred constant statically match.
20585 (Mentions_T): A reference to the current type in an anonymous access
20586 component declaration must be an entity name.
20587 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20588 class_wide type to refer to full type, not to the incomplete one.
20589 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20590 available. Required to give support to the certified run-time.
20591 (Analyze_Component_Declaration): In case of anonymous access components
20592 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20593 (Process_Discriminants): For an access discriminant, use the
20594 discriminant specification as the associated_node_for_itype, to
20595 simplify accessibility checks.
20597 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20598 Javier Miranda <miranda@adacore.com>
20600 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20601 abstract interpretations on an operator, remove interpretations that
20602 yield Address or a type derived from it, if one of the operands is an
20604 (Try_Object_Operation.Try_Primitive_Operation,
20605 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20606 location when creating the new reference to a primitive or class-wide
20607 operation as a part of rewriting a subprogram call.
20608 (Try_Primitive_Operations): If context requires a function, collect all
20609 interpretations after the first match, because there may be primitive
20610 operations of the same type with the same profile and different return
20611 types. From code reading.
20612 (Try_Primitive_Operation): Use the node kind to choose the proper
20613 operation when a function and a procedure have the same parameter
20615 (Complete_Object_Operation): If formal is an access parameter and prefix
20616 is an object, rewrite as an Access reference, to match signature of
20617 primitive operation.
20618 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20619 by an expanded name with prefix Standard, when the operands are of an
20620 anonymous access type.
20621 (Remove_Abstract_Operations): If the operation is abstract because it is
20622 inherited by a user-defined type derived from Address, remove it as
20623 well from the set of candidate interpretations of an overloaded node.
20624 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20627 2006-02-13 Bob Duff <duff@adacore.com>
20629 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20630 redundant use clauses.
20631 In particular, if the scope of two use clauses overlaps, but one is not
20632 entirely included in the other, we should not warn. This can happen
20633 with nested packages.
20634 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20635 reported errors. The bug was reported when the compiler was built
20636 with assertions enabled.
20637 (Find_Type): If the node is a 'Class reference and the prefix is a
20638 synchronized type without a corresponding record, return the type
20641 2006-02-13 Javier Miranda <miranda@adacore.com>
20643 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20644 if this is the full-declaration associated with a private declaration
20645 that implement interfaces, then the private type declaration must be
20647 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20648 as aliased. The use of the 'access attribute is not available for such
20649 object (for this purpose the object should be explicitly marked as
20650 aliased, but being an anonymous type this is not possible).
20652 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20653 Robert Dewar <dewar@adacore.com>
20655 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20656 compilation unit is an elaboration scope.
20657 (Add_Task_Proc): Add '\' in 2-line warning message.
20658 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20660 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20661 Javier Miranda <miranda@adacore.com>
20663 * sem_type.adb (Write_Overloads): Improve display of candidate
20665 (Add_One_Interp): Do not add to the list of interpretations aliased
20666 entities corresponding with an abstract interface type that is an
20667 immediate ancestor of a tagged type; otherwise we have a dummy
20668 conflict between this entity and the aliased entity.
20669 (Disambiguate): The predefined equality on universal_access is not
20670 usable if there is a user-defined equality with the proper signature,
20671 declared in the same declarative part as the designated type.
20672 (Find_Unique_Type): The universal_access equality operator defined under
20673 AI-230 does not cover pool specific access types.
20674 (Covers): If one of the types is a generic actual subtype, check whether
20675 it matches the partial view of the other type.
20677 2006-02-13 Thomas Quinot <quinot@adacore.com>
20679 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20680 line. This is necessary to allow In_Extended_Main_Unit to provide
20681 correct results for itypes while writing out expanded source.
20682 (Close_File): No need to update the source_index_table here since it's
20683 now done for each line.
20685 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20686 Robert Dewar <dewar@adacore.com>
20688 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20689 preserve the source unit where the itype is declared, and prevent a
20691 (Note_Implicit_Run_Time_Call): New procedure
20692 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
20695 * sprint.ads: Document use of $ for implicit run time routine call

20702 2006-02-13 Bob Duff <duff@adacore.com>
20704 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20705 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20706 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20707 raise Constraint_Error.
20709 * s-vallli.adb (Scan_Long_Long_Integer): Call
20710 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20711 do not scan leading blanks and sign twice.
20712 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20713 raise Constraint_Error.
20715 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20716 Scan_Long_Long_Unsigned): Split out most of the processing from
20717 Scan_Long_Long_Unsigned out into
20718 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20719 This prevents scanning leading blanks and sign twice.
20720 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20723 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20724 out most of the processing from Scan_Unsigned out into
20725 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20726 This prevents scanning leading blanks and sign twice.
20728 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20729 use with Modular'Value attribute.
20730 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
20733 2006-02-13 Robert Dewar <dewar@adacore.com>
20735 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value

20926 Florian Villoing <villoing@adacore.com>
20928 * a-taster.ads, a-taster.adb: New files.
20930 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
20931 link to the version that does nothing. This way the task termination
20932 routine is not executed twice for the environment task when finishing
20933 because of an unhandled exception.
20935 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
20936 handler because of an unhandled exception.
20938 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
20939 System.Tasking.Utilities instead of that in System.Tasking.Stages.

20942 finalization of the global list instead of Adafinal.
20944 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
20945 non-tasking version of the soft link for task termination. We do
20946 nothing since if we are using the non-tasking version it
20947 means that the task termination functionality is not used.
20948 (Null_Finalize_Global_List): Add this null version for the procedure
20949 in charge of finalizing the global list for controlled objects.
20950 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
20951 instead for handling run-time termination in a more flexible way.
20952 (Adafinal_NT): This new procedure will take care of finalizing the
20953 global list for controlled objects if needed, but no tasking
20956 * s-tarest.adb (Task_Lock): Do not try to lock again the
20957 Global_Task_Lock if we already own it. Otherwise, we get blocked in
20958 some run-time operations.
20959 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
20960 until all nested locks have been released.
20961 (Task_Wrapper): Call the fall-back task termination handler. It
20962 applies to all tasks but the environment task.
20963 (Finalize_Global_Tasks): Add the call for the task termination
20964 procedure for the environment task.
20965 (Task_Wrapper): suppress warnings around declaration of
20966 Secondary_Stack_Address.
20968 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
20969 moved to the Common_ATCB record.
20970 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
20971 Common_ATCB record.
20972 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
20973 Common_ATCB record.
20975 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
20976 Fall_Back_Handler, and Specific_Handler.
20978 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
20979 defined in Ada.Task_Termination, to avoid circular dependencies.
20980 (Termination_Handler): Redefine this type here, alredy defined in
20981 Ada.Task_Termination, for avoiding circular dependencies.
20982 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
20983 for storing task termination handlers. In addition,
20984 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
20985 Common_ATCB because it is used by both the regular and the restricted
20987 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
20988 Common_ATCB because it is used by both the regular and the restricted
20990 (Common_ATCB): Added a dynamic task analyzer field.
20992 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
20993 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
20994 (Task_Wrapper): Call the task termination handler. It applies to all
20995 tasks but the environment task.
20996 (Finalize_Global_Tasks): Call the task termination procedure for the
20997 environment task. The call to Finalize_Global_List is now performed
20998 using the soft links mechanism.
20999 (Task_Wrapper): added dynamic stack analysis.
21001 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21002 potentially blocking operations has been moved from
21003 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21004 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21005 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21006 this run-time check.
21008 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21009 of task termination procedure.
21010 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21011 link for the task termination procedure.

21026 * s-io.ads, s-io.adb (Standard_Error): new subprogram
21027 (Standart_Output): new subprogram
21028 (Set_Output): new subprogram
21029 (Put): now uses the value of Current_Out to know if the output has to be
21030 send to stderr or stdout.
21032 * s-stausa.ads: Complete implementation.
21034 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
21036 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
21037 list of Ada 05 files.
21038 (GNAT Library Units): Add AltiVec files.

21047 file_name is empty.
21049 2005-12-09 Javier Miranda <miranda@adacore.com>
21050 Hristian Kirtchev <kirtchev@adacore.com>
21052 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21053 to the specification because the frontend generates code that uses this
21055 (Set_Interface_Table): Add missing assertion.
21056 Update documentation describing the run-time structure.
21057 (Displace): New subprogram that displaces the pointer to the object
21058 to reference one of its secondary dispatch tables.
21059 (IW_Membership): Modified to use the new table of interfaces.
21060 (Inherit_TSD): Modified to use the new table of interfaces.
21061 (Register_Interface_Tag): Use the additional formal to fill the
21062 contents of the new table of interfaces.
21063 (Set_Interface_Table): New subprogram that stores in the TSD the
21064 pointer to the table of interfaces.
21065 (Set_Offset_To_Top): Use the additional formal to save copy of
21066 the offset value in the table of interfaces.

21078 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21079 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21080 record component containing the tag of the secondary dispatch table we
21081 have to use the Offset_To_Top run-time function to get this information;
21082 otherwise if the pointer to the base of the object has been displace
21083 we get a wrong value if we use the 'position attribute.
21085 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21086 all the calls to Expand_Interface_Thunk.
21087 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
21088 interfaces; hence the call to Set_Interface_Table was clearly wrong.
21089 (Collect_All_Interfaces): Modify the internal subprogram Collect to
21090 ensure that the interfaces implemented by the ancestors are placed
21091 at the header of the generated list.
21092 (Expand_Interface_Conversion): Handle the case in which the displacement
21093 associated with the interface conversion is not statically known. In
21094 this case we generate a call to the new run-time subprogram Displace.
21095 (Make_DT): Generate and fill the new table of interfaces.
21096 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21097 Get_Tagged_Kind and Set_Tagged_Kind.
21098 (Tagged_Kind): New function that determines the tagged kind of a type
21099 with respect to limitedness and concurrency and returns a reference to
21101 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
21102 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
21103 primary dispatch table for a type.
21104 (Make_DT, Make_Secondary_DT): Set the tagged kind in the primary and
21105 secondary dispatch table respectively of a tagged type.
21107 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
21108 (Expand_Interface_Conversion): New subprogram to indicate if the
21109 displacement of the type conversion is statically known.
21110 (DT_Access_Action): Add values Get_Tagged_Kind and Set_Tagged_Kind.
21112 * rtsfind.ads (RE_Offset_To_Top): New entity
21113 (RTU_Id): Add Ada_Task_Termination to the list so that it is made
21114 accessible to users.
21115 (Re_Displace): New entity

21117 (RE_Set_Interface_Data): New_Entity
21118 (RE_Id, RE_Unit_Table): Add entry for RE_Get_Tagged_Kind,
21119 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
21120 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
21121 RE_TK_Tagged, RE_TK_Task.
21123 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21124 Init_Secondary_Tags_Internal to allow its use with interface types and
21125 also to generate the code for the new additional actual required
21126 by Set_Offset_To_Top.
21127 (Build_Init_Statements): In case of components associated with abstract
21128 interface types there is no need to generate a call to its IP.
21129 (Freeze_Record_Type): Generate Select Specific Data tables only for
21131 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21132 the bodies and specifications of the predefined primitive operations
21133 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21134 for concurrent types.
21136 * exp_sel.ads, exp_sel.adb: New files.
21138 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21139 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21140 properly protected objects and attach handler in the case of the
21141 restricted profile.
21142 Move embeded package Select_Expansion_Utilities into a separate external
21144 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
21145 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
21146 (Build_K, Build_S_Assignment): New subprograms, part of the select
21147 expansion utilities.
21148 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Entry_Call,

21150 where the trigger is a dispatching procedure of a limited tagged type.
21152 2005-12-09 Olivier Hainque <hainque@adacore.com>
21154 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21155 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21156 about the use and expansion of SAVE_EXPRs in the various possible
21157 renaming handling cases.
21158 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21159 abusing DECL_FCONTEXT.
21161 2005-12-09 Matthew Heaney <heaney@adacore.com>

21280 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
21281 base type to create anonymous subtype, because entity may be a locally
21282 declared subtype or generic actual.
21283 (Find_Interface): New subprogram that given a tagged type and one of its
21284 component associated with the secondary table of an abstract interface
21285 type, return the entity associated with such abstract interface type.
21287 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
21288 conversion cannot be handled at compile time. In this case we pass this
21289 information to the expander to generate the appropriate code.

21326 (Analyze_Component_Declaration): A limited component is
21327 legal within a protected type that implements an interface.
21328 (Collect_Interfaces): Do not add to the list the interfaces that
21329 are implemented by the ancestors.
21330 (Derived_Type_Declaration): If the parent of the full-view is an
21331 interface perform a transformation of the tree to ensure that it has
21332 the same parent than the partial-view. This simplifies the job of the
21333 expander in order to generate the correct object layout, and it is
21334 needed because the list of interfaces of the full-view can be given in
21336 (Process_Full_View): The parent of the full-view does not need to be
21337 a descendant of the parent of the partial view if both parents are
21339 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21340 "limited" the parent must be a limited type.

21354 (Process_Full_View): Improve the check for the "no hidden interface"
21355 rule as defined by AI-396.
21357 2005-12-09 Robert Dewar <dewar@adacore.com>

21414 available user-specified stream attributes on limited parameters to
21415 also test the type directly rather than only its underlying type (for
21416 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21417 attributes are visible at the point of the subprogram declaration.
21418 For Ada 2005, the error message is modified to indicate that the
21419 type's stream attributes must be visible (again, only for -gnat05).

21451 types use the corresponding record type. This was not needed before
21452 the implementation of Ada 2005 synchronized types because
21453 concurrent types were never tagged types in Ada 95.

21581 * socket.c: Add extern int h_errno for rtems since networking header
21582 files are not available at this point in a tool bootstrap. Newlib

21692 deal with different cases of static and dynamic elaboration checks (all
21693 checks does not count in the first case, but does in the second).

21699 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
21700 elementary types using the operator in standard. It is cleaner not to
21701 modify the programmers intent, especially in the case of floating-point.
21702 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
21703 it did not matter because we always rewrote a/=b to not(a=b).
21704 (Expand_Allocator_Expression): For an allocator expression whose nominal

21858 we are not defining the type.
21859 <E_Record_Type>: Likewise.
21860 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
21861 to get advantage of the new maybe_stabilize_reference interface, to
21862 ensure that what we reference is indeed stabilized instead of relying
21863 on assumptions on what the stabilizer does.
21864 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
21865 type imported through a limited_with clause, use its non-limited view.
21866 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
21868 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
21869 of #if sections + explicit comparisons of convention identifiers.

21871 before early-returning for certain types when code generation is
21873 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

21875 that we are not defining.
21876 (elaborate_expression_1): Do not create constants when creating
21877 variables needed by the debug info: the dwarf2 writer considers that
21878 CONST_DECLs is used only to represent enumeration constants, and emits
21880 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
21881 object with an address clause into an indirect reference, drop the
21882 initializing expression.
21884 (STACK_CHECK_BUILTIN): Delete.
21885 (STACK_CHECK_PROBE_INTERVAL): Likewise.

21894 subtype to build an actual type with bounds template.
21895 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
21896 is provided by the front-end, use that subtype to compute the size of
21897 the deallocated object.

21899 check for a potential violation of a No_Elaboration_Code restriction.

21904 maybe_stabilize, for common uses without restriction on lvalues and
21905 without need to check for the success indication.
21906 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
21907 pass false instead of 0 as the FORCE argument which is a bool.
21908 (Identifier_to_gnu): Remove checks ensuring that an renamed object
21909 attached to a renaming pointer has been properly stabilized, as no such
21910 object is attached otherwise.
21911 (call_to_gnu): Invoke create_var_decl to create the temporary when the
21912 function uses the "target pointer" return mechanism.
21913 Reinstate conversion of the actual to the type of the formal
21914 parameter before any other specific treatment based on the passing
21915 mechanism. This turns out to be necessary in order for PLACEHOLDER
21916 substitution to work properly when the latter type is unconstrained.

21924 * utils2.c (gnat_build_constructor): Only sort the fields for possible
21925 static output of record constructor if all the components are constant.
21926 (gnat_build_constructor): For a record type, sort the list of field
21927 initializers in increasing bit position order.
21928 Factor common code to build a storage type for an unconstrained object
21929 from a fat or thin pointer type and a constrained object type.
21930 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
21931 types variants, and process special cases of VIEW_CONVERT expressions
21932 as their NOP_EXPR counterpart to ensure we get to the
21933 CORRESPONDING_VARs associated with CONST_DECls.
21934 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
21935 on the right-hand side.

21942 extracting the object if converting to a type variant.
21943 (create_var_decl): When a variable has an initializer requiring code
21944 generation and we are at the top level, check for a potential violation
21945 of a No_Elaboration_Code restriction.
21946 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
21947 SIZE and SIZE_UNIT which we need for later back-annotations.

22133 'Unrestricted_Access, if the designated type is an interface we
22134 add a type conversion to force the displacement of the pointer

22487 full view to construct the full declaration of the derived type.
22488 (Build_Derived_Record_Type): Relax the condition that controls the
22489 execution of the check that verifies that the partial view and

22499 (Process_Full_View): Rename local subprogram Find_Interface_In_
22500 Descendant to Find_Ancestor_Interface to leave the code more clear.
22501 Remove wrong code that avoids the generation of an error message
22502 when the immediate ancestor of the partial view is an interface.
22503 In addition some minor reorganization of the code has been done to
22504 leave it more clear.
22505 (Analyze_Type_Declaration): If type has previous incomplete tagged
22506 partial view, inherit properly its primitive operations.
22507 (Collect_Interfaces): Make public, for analysis of formal

22520 be included in the interface list.
22521 (Access_Definition): If the designated type is an interface that may
22522 contain tasks, create Master_Id for it before analyzing the expression
22523 of the declaration, which may be an allocator.

22534 subprogram declaration.
22535 Change name Is_Package to Is_Package_Or_Generic_Package
22536 (Process_Formals): A non null qualifier on a non null named access

22545 declarations and use clauses within each of the parent units of a
22546 package instance of a generic child package.

22548 package associated with a generic instance or formal package, the
22549 private declarations of the parent must be installed (by calling new
22550 procedure Install_Parent_Private_Declarations).
22551 Change name Is_Package to Is_Package_Or_Generic_Package
22552 (Preserve_Full_Attributes): For a synchronized type, the corresponding

22558 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22559 not try to rewrite a renamed stream attribute, because the operations
22560 on the type may not have been generated.
22561 Handle properly a renaming_as_body generated for a stream operation
22562 whose default is abstract because the object type itself is abstract.
22563 (Find_Type): If the type is incomplete and appears as the prefix of a
22564 'Class reference, it is tagged, and its list of primitive operations
22565 must be initialized properly.
22566 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22567 private declaration of a parent unit, prior to compiling the private
22568 part of a child unit, find on the scope stack the proper parent entity
22569 on which to link the use clause.

22590 a procedure call is used as a select statement trigger and is not an
22591 entry renaming or a primitive of a limited interface.
22592 (Valid_Conversion): If the operand has a single interpretation do not
22593 remove address operations.
22594 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22595 statement to inhibit warning.
22596 (Resolve_Unary_Op): Do not produce a warning when
22597 processing an expression of the form -(A mod B)
22598 Use Universal_Real instead of Long_Long_Float when we need a high

22601 (Resolve_Concatenation_Arg): Improve error message when argument is an
22602 ambiguous call to a function that returns an array.
22603 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

23640 position set is provided, we compute one in order to reduce the maximum
23641 length of the keys. This computation first selects a character
23642 position between 1 and the minimum length of the keys in order to
23643 avoid reducing one of the keys to an empty string.
23644 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23645 does not converge. The initialization procedure now comes with a
23646 maximum number of iterations such that when exceeded, an exception is

23747 * sem_prag.adb Implement new pragma Debug_Policy
23748 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23749 Component_Size attribute specification. Give warning for ignored pragma
23752 * snames.h, snames.ads, snames.adb: Introduce entries in
23753 Preset_Names for Name_Disp_Asynchronous_Select,
23754 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23755 Name_Disp_Timed_Select.
23756 New pragma Debug_Policy
23758 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23760 Switch -gnata also sets Debug_Pragmas_Enabled
23762 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23763 handle an explicit -gnata when compiling predefined files.
23765 2005-09-01 Vincent Celier <celier@adacore.com>
23767 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23768 directories of projects that have no Ada sources.
23770 2005-09-01 Robert Dewar <dewar@adacore.com>
23772 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23773 (makes a difference for wide characters)
23775 * widechar.adb, widechar.ads:
23776 Add Wide_Char_Byte_Count feature to count chars vs bytes
23778 2005-09-01 Thomas Quinot <quinot@adacore.com>
23779 Ed Schonberg <schonberg@adacore.com>
23780 Robert Dewar <dewar@adacore.com>
23782 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23783 'Address attribute reference with an overloaded prefix, use the
23784 location of the prefix (not the location of the attribute reference) as
23785 the error location.
23786 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23787 a function renaming thereof, is a valid prefix for 'Size (where it is
23788 intepreted as a function call).
23789 (Statically_Denotes_Entity): New predicate to determine whether the
23790 prefix of an array attribute can be considered static.
23793 (Eval_Attr): Fix failure to evaluate Component_Size for
23794 unconstrained arrays (resulted in wrong value in packed case, since
23795 back end cannot handle this case)
23797 2005-09-01 Robert Dewar <dewar@adacore.com>
23799 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23800 error msgs for most common cases.
23801 Use new errout insertion char < (conditional warning)
23803 2005-09-01 Javier Miranda <miranda@adacore.com>
23804 Ed Schonberg <schonberg@adacore.com>
23806 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23807 become local to the whole package.
23808 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23809 the package was already analyzed the new algorithm "replaces" the
23810 real entities by the shadow ones. This is required to ensure that
23811 the order of these entities in the homonym chains does not change;
23812 otherwise we can have undefined references at linking time because
23813 in case of conflicts the external name of the entities will have
23814 a suffix that depends on the order of the entities in the chain.
23815 (Remove_Limited_With_Clause): Complementary code that completes the
23816 new algorithm and replaces the shadow entities by the real ones.
23817 (Install_Limited_Withed_Unit): When unchaining entities before the
23818 installation of the shadow entities, only regular entities of the
23819 public part must be taken into account. This is required to
23820 keep this routine in synch with the work done by Remove_Limited_
23822 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
23823 even if unit is analyzed, because the analysis of the unit is
23824 idempotent in any case, and the limited view of the unit may have to
23825 be installed for proper visibility.
23826 (Expand_Limited_With_Clause): Even if the unit in the implicit
23827 with_clause has been analyzed already, a limited view of the package
23828 must be built for the current context, if it does not exist yet.
23830 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23831 Javier Miranda <miranda@adacore.com>
23832 Gary Dismukes <dismukes@adacore.com>
23834 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
23835 defining entity for the instance body, make a new defining identifier
23836 rather than copying the entity of the spec, to prevent accidental
23837 sharing of the entity list.
23838 (Check_Private_View): When exchanging views of private types, build the
23839 list of exchanged views as a stack, to ensure that on exit the exchanges
23840 are undone in the proper order.
23841 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
23842 Restore the compilation environment in case of instantiation_error.
23843 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
23844 for an anonymous access result.
23845 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
23846 (Formal_Entity): Handle properly the case of a formal package that
23847 denotes a generic package renaming.
23849 2005-09-01 Thomas Quinot <quinot@adacore.com>
23851 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
23852 clause if the array aggregate is surrounded by parentheses.
23854 2005-09-01 Cyrille Comar <comar@adacore.com>
23855 Gary Dismukes <dismukes@adacore.com>
23856 Ed Schonberg <schonberg@adacore.com>
23857 Javier Miranda <miranda@adacore.com>
23859 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
23861 to check if a type is Constrained in cases related to code generation
23862 (rather than semantic checking) since otherwise we do not generate
23863 similar code for mutable private types depending if their
23864 discriminants are visible or not.
23865 (Check_Abstract_Overriding): Do not complain about failure to override
23866 the primitive operations used in dispatching selects since they will
23867 always be overriden at the freeze point of the type.
23868 (Access_Definition): Separate out handling for resetting the scope
23869 of an anonymous access function result type. Retrieve the scope
23870 of the associated function rather than using Current_Scope, which
23871 does not have a consistent value (depends on whether we're in the
23872 middle of analyzing formal parameters). Add ??? comment about
23873 finding a cleaner way to handle the special cases of scope setting.
23874 (Process_Incomplete_Dependents): A protected operation is never a
23875 dispatching operation (only its wrapper may be).
23876 (Build_Derived_Record_Type): In case of tagged private types that
23877 implement interfaces add derivation of predefined primitive
23879 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
23880 by two parameters that are used in case of derivation from abstract
23881 interface types: No_Predefined_Prims is used to avoid the derivation
23882 of predefined primitives from the interface, and Predefined
23883 Prims_Only is used to complete the derivation predefined primitives
23884 in case of private tagged types implementing interfaces.
23885 Fix typo in comments
23886 (Find_Interface_In_Descendant): Protect the frontend against
23887 wrong code with large circularity chains.
23888 (Is_Private_Overriding): Add support for entities overriding interface
23889 subprograms. The test failed because Entities associated with overriden
23890 interface subprograms are always marked as hidden (and used to build
23891 the secondary dispatch table); in this case the overriden entity is
23892 available through the field abstract_interface_alias (cf. override_
23893 dispatching_operation)
23894 (Access_Definition): Set the scope of the type to Current_Scope for the
23895 case of a function with an anonymous access result type.
23896 (Access_Subprogram_Declaration): Handle creation of the type entity for
23897 an access-to-function type with an anonymous access result.
23898 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
23899 in handling for N_Access_Function_Definition.
23900 (Analyze_Subtype_Declaration): Modify the text of error message.
23901 (Derived_Type_Declaration): Modify the text of error message.
23902 (Process_Subtype): Modify the text of error message plus cleanup
23903 of one redundant error message.
23904 (Analyze_Component_Declaration): Code cleanup.
23905 (Analyze_Object_Declaration): Code cleanup.
23906 (Analyze_Subtype_Declaration): Propagate the null-exclusion
23907 attribute in case of access types. Code cleanup.
23908 (Array_Type_Declaration): Code cleanup.
23909 (Process_Discriminants): Create the new null-excluding itype
23910 if required. Code cleanup.
23911 (Process_Subtype): Create the new null-excluding itype if
23912 required. Code cleanup.
23913 (Build_Derived_Record_Type): Code cleanup to avoid calling
23914 twice the subprogram derive_subprograms in case of private
23915 types that implement interfaces. In this particular case the
23916 subprogram Complete_Subprograms_Derivation already does the
23917 job associated with the second call.
23919 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
23920 conversion to the full view when generating an operation for a
23921 discriminant whose type may currently be private.
23923 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23924 Javier Miranda <miranda@adacore.com>
23926 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
23927 V (Obj.F), the rewriting does not involve the indexed component, but
23928 only the selected component itself.
23929 Do not apply the transformation if the analyzed node is an actual of a
23930 call to another subprogram.
23931 (Complete_Object_Operation): Retain the entity of the
23932 dispatching operation in the selector of the rewritten node. The
23933 entity will be used in the expansion of dispatching selects.
23934 (Analyze_One_Call): Improve location of the error message associated
23936 (Analyze_Selected_Component): No need to resolve prefix when it is a
23937 function call, resolution is done when parent node is resolved, as
23939 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
23940 when attempting to resolve a call transformed from its object notation.
23941 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
23942 of the argument list for each interpretation of the operation.
23943 (Try_Object_Operation): The designated type of an access parameter may
23944 be an incomplete type obtained through a limited_with clause, in which
23945 case the primitive operations of the type are retrieved from its full
23947 (Analyze_Call): If this is an indirect call, and the return type of the
23948 access_to_subprogram is incomplete, use its full view if available.
23950 2005-09-01 Javier Miranda <miranda@adacore.com>
23951 Gary Dismukes <dismukes@adacore.com>
23953 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
23954 access types the null-exclusion and access-to-constant attributes must
23956 (Analyze_Return_Statement): When the result type is an anonymous access
23957 type, apply a conversion of the return expression to the access type
23958 to ensure that appropriate accessibility checks are performed.
23959 (Analyze_Return_Type): For the case of an anonymous access result type,
23960 generate the Itype and set Is_Local_Anonymous_Access on the type.
23961 Add ??? placeholder for check to disallow returning a limited object
23962 in Ada 2005 unless it's an aggregate or a result of a function call.
23963 Change calls from Subtype_Mark to Result_Definition.
23964 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
23965 Result_Definition in call to Make_Function_Specification.
23966 (Build_Body_To_Inline): Change Set_Subtype_Mark to
23967 Set_Result_Definition.
23968 (Make_Inequality_Operator): Change formal Subtype_Mark to
23969 Result_Definition in call to Make_Function_Specification.
23970 (Process_Formals): Create the new null-excluding itype if required.
23971 (New_Overloaded_Entity): For an entity overriding an interface primitive
23972 check if the entity also covers other abstract subprograms in the same
23973 scope. This is required to handle the general case, that is, overriding
23974 other interface primitives and overriding abstract subprograms inherited
23975 from some abstract ancestor type.
23976 (New_Overloaded_Entity): For an overriding entity that comes from
23977 source, note the operation that it overrides.
23978 (Check_Conformance, Type_Conformant): Addition of one new formal
23979 to skip controlling formals in the analysis. This is used to
23980 handle overloading of abstract interfaces.
23981 (Base_Types_Match): Add missing case for types imported from
23982 limited-with clauses
23983 (New_Overloaded_Entity): Add barrier to protect the use of
23984 the "alias" attribute.
23986 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23988 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
23989 verify that the procedure and the entry are mode conformant.
23990 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
23991 as a different operator, which is often a cut-and-paste error.
23993 2005-09-01 Javier Miranda <miranda@adacore.com>
23994 Ed Schonberg <schonberg@adacore.com>
23996 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
23997 used in controlling parameters exclude null because it is necessary to
23998 read the tag to dispatch, and null has no tag.
23999 (Override_Dispatching_Operation): If the previous operation is inherited
24000 from an interface, it becomes hidden and does not participate in later
24003 2005-09-01 Javier Miranda <miranda@adacore.com>
24004 Ed Schonberg <schonberg@adacore.com>
24005 Gary Dismukes <dismukes@adacore.com>
24007 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24008 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24009 the expander will generate the corresponding run-time check to evaluate
24011 (Resolve_Call): Check for legal type of procedure name or prefix that
24012 appears as a trigger in a triggering alternative.
24013 (Valid_Conversion): If expression is ambiguous and the context involves
24014 an extension of System, remove System.Address interpretations.
24015 (Resolve_Qualified_Expression): Reject the case of a specific-type
24016 qualification applied to a class-wide argument. Enhance comment
24017 to explain checking of Original_Node.
24018 (Resolve_Type_Conversion): The location of the error message was not
24019 general enough to handle the general case and hence it has been removed.
24020 In addition, this patch improves the text of the message.
24021 (Resolve_Type_Conversion): Add missing support for access to interface
24023 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24024 do not expand if the expression is the actual in a call, because proper
24025 expansion will take place when the call itself is expanded.
24026 (Resolve_Allocator): If the context is an unchecked conversion, the
24027 allocator inherits its storage pool, if any, from the target type of
24030 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24031 Javier Miranda <miranda@adacore.com>
24033 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24034 inherited interface operation that has an implementation, use the
24035 implementation to avoid spurious ambiguities.
24036 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24037 use the Corresponding_Record_Typ attribute to look for the interface
24038 because it is set by the expander (and hence it is not always
24039 available). For this reason we traverse the list of interfaces
24040 (available in the parent of the concurrent type).
24041 (Interface_Present_In_Ancestor): Handle entities from the limited view
24043 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24045 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24046 from the list of required components.
24047 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24048 primitive procedure of a limited interface with a controlling first
24050 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24052 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24053 capture if it is generated in the second operand of a short-circuit
24055 Do not capture values for variables with address clauses.
24056 (Is_Object_Reference): Treat a function call as an object reference only
24057 if its type is not Standard_Void_Type.
24059 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24061 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24062 to a variable that is statically known to be constant.
24064 2005-09-01 Geert Bosch <bosch@adacore.com>
24065 Robert Dewar <dewar@adacore.com>
24067 * ttypef.ads (VAXDF_Safe_First): Use correct value for constant.
24068 (VAXGF_Safe_First): Idem.

24071 Arnaud Charlet <charlet@adacore.com>
24073 * g-dirope.ads: Minor reformatting
24074 Document that bounds of result of Base_Name match the input index
24076 Add documentation on environment variable syntax for Expand_Path
24078 * gnat_ugn.texi: Update documentation to include mention of -m switches
24079 Document new treatment of wide characters in max line length
24081 Remove -gnatL/-gnatZ switches, no longer used.
24082 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24085 * gnat_rm.texi: Add doc for two argument form of pragma
24086 Float_Representation.
24087 Add documentation for pragma No_Strict_Aliasing
24088 Add note that explicit component clause overrides pragma Pack.
24089 Add documentation of pragma Debug_Policy

24844 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
24845 longer protected objects. They have been replaced by lower-level
24846 suspension objects made up by a mutex and a condition variable (or
24847 their equivalent given a particular OS) plus some internal data to
24848 reflect the state of the suspension object.
24849 (Initialize, Finalize): Add this initialization procedure for
24850 Suspension_Object, which is a controlled type.
24851 (Finalize): Add the finalization procedure for Suspension_Object,
24852 which is a controlled type.
24854 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
24855 Ada.Synchronous_Task_Control because there is no longer a need for a
24856 VxWorks specific version of this package. Target dependencies
24857 has been moved to System.Task_Primitives.Operations.
24859 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
24861 (InitializeCriticalSection, EnterCriticalSection,
24862 LeaveCriticalSection, DeleteCriticalSection): Replace the type
24863 pCriticalSection by an anonymous access type so that we avoid problems
24864 of accessibility to local objects.

24870 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
24871 set the environment task mask here.
24872 (Current_State): Add this function that returns the state of the
24874 (Set_False): Add this procedure that sets the state of the suspension
24876 (Set_True): Add this procedure that sets the state of the suspension
24877 object to True, releasing the task that was suspended, if any.
24878 (Suspend_Until_True): Add this procedure that blocks the calling task
24879 until the state of the object is True. Program_Error is raised if
24880 another task is already waiting on that suspension object.
24881 (Initialize): Add this procedure for initializing the suspension
24882 object. It initializes the mutex and the condition variable which are
24883 used for synchronization and queuing, and it sets the internal state
24885 (Finalize): Add this procedure for finalizing the suspension object,
24886 destroying the mutex and the condition variable.

24891 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
24892 which provides a low-level abstraction (using operating system
24893 primitives) for Ada.Synchronous_Task_Control.
24894 This object is made up by a mutex (for ensuring mutual exclusion), a
24895 condition variable (for queuing threads until the condition is
24896 signaled), a Boolean (State) indicating whether the object is open,
24897 and a Boolean (Waiting) reflecting whether there is a task already
24898 suspended on this object.

24906 (Setup_Interrupt_Mask): New procedure.
24908 * s-intman-vxworks.ads, s-intman-vxworks.adb: Update comments.
24910 * s-inmaop.ads (Setup_Interrupt_Mask): New procedure
24912 * s-interr.adb: Add explicit call to Setup_Interrupt_Mask now that
24913 this is no longer done in the body of s-taprop
24914 (Server_Task): Explicitely test for Pending_Action in case
24915 System.Parameters.No_Abort is True.
24917 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
24918 is no longer done in the body of s-taprop

25163 type derivation of private tagged types implementing interfaces.
25164 In this case some interface primitives may have been overriden

25254 * i-cpp.ads, i-cpp.adb:
25255 This package has been left available for compatibility with previous
25256 versions of the frontend. As part of the new layout this is now a

25310 access to subprograms must be recursive.
25311 (Is_Unchecked_Conversion): Improve the test that recognizes
25312 instantiations of Unchecked_Conversion, and allows them in bodies that
25313 are to be inlined by the front-end. When the body comes from an

25336 object or component (that is, when Is_Local_Anonymous_Access is true).
25337 Prevent the special checks for conversions of access discriminants in
25338 the case where the discriminant belongs to a nonlimited type, since
25339 such discriminants have their accessibility level defined in the same
25340 way as a normal component of an anonymous access type.
25341 (Resolve_Allocator): When an allocator's designated type is a class-wide
25342 type, check that the accessibility level of type given in the
25343 allocator's expression or subtype indication is not statically deeper

25360 pragma Restrictions (No_Obsolescent_Features).
25361 (Check_Direct_Boolean_Operator): If the boolean operation has been
25362 constant-folded, there is nothing to check.
25363 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25364 check on possible violation of restriction No_Direct_Boolean_Operators
25365 until after expansion of operands, to prevent spurious errors when

26360 * exp_ch4.adb (Has_Unconstrained_UU_Component): Use the base type in
26361 order to retrieve the component list of the type, before examining
26362 individual components.
26364 * sem_type.adb (Covers): Types are compatible if one is the base type
26365 of the other, even though their base types might differ when private
26366 views are involved.

26370 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26371 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26372 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26373 analyzed if expansion is disabled (which could otherwise cause spurious
26374 error messages if expansion has been disabled due to previous
26375 (unrelated) errors).
26377 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26378 is disabled, the entity denoted by the argument is the access type
26379 itself, not an underlying record type, so there is no need to go back
26380 to the Corresponding_Remote_Type.
26382 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26383 Robert Dewar <dewar@adacore.com>
26385 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
26386 expand a call to an instance of
26387 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
26388 Constructor actual of the instance. A class-wide membership
26389 check is also generated, to ensure that the tag passed to the instance
26390 denotes a type in the class.
26391 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26392 of Name_Generic_Dispatching_Constructor.
26394 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26395 05 unit for AI-260-02).

26407 character type cases.
26408 (Analyze_Subprogram_Renaming): Add special handling for
26409 the case of renaming of stream attributes when the renaming denotes a
26410 generic formal subprogram association for an abstract formal subprogram.
26411 Check that the attribute is a primitive stream attribute (and not
26412 a class-wide stream attribute) and then rewrite the attribute name
26413 as the name of the appropriate compiler-generated stream primitive.
26415 2005-03-29 Robert Dewar <dewar@adacore.com>
26417 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to
26419 (Is_Possibly_Unaligned_Object): Correct typo that
26420 resulted in inaccurate result for unaligned scalars within records.
26422 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26424 * freeze.adb (Freeze_Record_Type): If the type of the component is an
26425 itype whose parent is controlled and not yet frozen, do not create a
26426 freeze node for the itype if expansion is disabled.
26428 2005-03-29 Vincent Celier <celier@adacore.com>
26430 * make.adb (Gnatmake): Don't fail if the main project file is declared
26431 as having no Ada sources. Do not display message "no sources to
26432 compile" in quiet output.
26434 2005-03-29 Doug Rupp <rupp@adacore.com>
26436 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26447 missing TYPE Improve the error message generated when compiling a
26448 limited interface in Ada83 or Ada95 mode.
26450 2005-03-29 Robert Dewar <dewar@adacore.com>
26452 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26453 rather than proceed ahead using a junk attribute name.
26455 2005-03-29 Vincent Celier <celier@adacore.com>
26457 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26459 * prj-part.adb (Parse_Single_Project): Set the location of a project
26460 on its defining identifier, rather than on the reserved word "project".
26462 * prj-proc.adb (Expression): Adapt to the fact that default of external
26463 references may be string expressions, not always literal strings.
26464 (Recursive_Process): Set Display_Name equal to Name
26465 when Location is No_Location, that is when there is no actual file.
26466 Get the Display_Name of the project from the source, when it is not a
26468 (Process): Use the Display_Name in error messages
26470 * prj-strt.adb (External_Reference): Allow default to be string
26471 expressions, not only literal strings.
26473 2005-03-29 Vincent Celier <celier@adacore.com>
26475 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
26476 file and the reference symbol file to be the same file.

26480 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
26481 forbid conversion of a local access-to-subprogram type to a remote one.
26483 * sem_util.adb (Wrong_Type): For a record type that is the expanded
26484 equivalent type for a remote access-to-subprogram type, go back to the
26485 original RAS entity when displaying an error message, so the casing is
26486 the original source casing.
26488 2005-03-29 Robert Dewar <dewar@adacore.com>
26490 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
26493 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26495 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26496 subtype if code is being pre-analyzed, to prevent un-expanded
26497 references to protected formals, among others.
26498 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26499 interpretation that can be a call, include the result of the call as a
26500 possible interpretation of the dereference.
26502 * sem_ch5.adb (Process_Bounds): Determine type of range by
26503 pre-analyzing a copy of the original range, and then analyze the range
26504 with the expected type.
26506 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26507 with an overloaded prefix where not all interpretations yield an
26508 access to subprogram, do not rewrite node as a call.
26509 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26510 the node as a call once the context identifies the interpretation of
26511 the prefix whose call yields the context type.
26512 (Valid_Conversion): For the case of a conversion between
26513 local access-to-subprogram types, check subtype conformance using
26514 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26515 detailed error message.

26519 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26520 indicator, indicate that the formal can never be null.
26521 (Process_Formals): If a formal has a non_null indicator, insert the
26522 resulting subtype immediately before the enclosing subprogram decl,
26523 and not at the beginning of the corresponding declarative part, to
26524 prevent access before elaboration (Ada2005).

26647 explanatory error message (including the name of the missing attribute).
26648 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
26649 subprogram determines whether a default implementation exists for a
26650 given stream attribute.
26651 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
26652 Determine whether to generate a default implementation for each stream
26653 attribute separately, as this depends on the specific attribute.
26655 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
26656 limited extension where a stream attribute is missing for a limited
26657 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

26696 the default for the tree, not the global default naming.
26698 * prj-proc.adb (Recursive_Process): No need to put the default naming
26699 in the project data, it's already there.

27190 These subprogram have been removed because the attribute
27191 Task_Body_Procedure has been moved to the corresponding task type
27192 or task subtype entity to leave a field free to store the list
27193 of interfaces implemented by a task (for AI-345)

27310 it is one or is derived from one, or because its completion is derived
27312 (Constrain_Component_Type): If component comes from source and has no
27313 explicit constraint, no need to constrain in in a subtype of the

27322 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27323 function returns "by target", dereference the target pointer using the
27324 type of the actual return value.
27325 <all>: Be prepared for a null gnu_result.
27326 (processed_inline_subprograms): Check flag_really_no_inline
27327 instead of flag_no_inline.
27328 (set_second_error_entity): Remove unused function.
27329 (gnat_to_gnu, case N_Selected_Component): Call
27330 gnat_to_gnu_field_decl.

27334 Ed Schonberg <schonberg@adacore.com>
27335 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27337 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27338 Must_Be_Byte_Aligned for cases where we do not need to use a
27339 System.Pack_nn unit.
27341 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27343 Needed now that we do some processing for IN parameters as well. This
27344 may well fix some unrelated errors.
27345 (Expand_Call): Handle case of unaligned objects (in particular those
27346 that come from packed arrays).
27347 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27348 renamed entity is an inherited operation, re-expand the call using the
27349 original operation, which is the one to call.
27350 Detect attempt to inline parameterless recursive subprogram.
27351 (Represented_As_Scalar): Fix to work properly with private types
27352 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27353 accurate estimate. Yields True in far fewer cases than before,
27354 improving the quality of code that depends on this test.
27356 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27357 over both visible and private declarations to remove them from tree,
27358 and mark subprograms declared in package as eliminated, to prevent
27359 spurious use in subsequent compilation of generic units in the context.
27361 * exp_util.ads: Minor cleanup in variable names
27363 * sem_eval.ads, sem_eval.adb: Minor reformatting
27364 (Compile_Time_Known_Bounds): New function
27366 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27368 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27369 determining whether an unchecked conversion is needed for the argument
27370 of an initialization call.
27372 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27374 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27375 that appears in the instantiation rather than the internal subtype
27376 generated in the wrapper package, to avoid anomalies in gigi when the
27377 target is derived from a private type whose full view is an access type.
27379 2005-03-15 Robert Dewar <dewar@adacore.com>
27381 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27383 Add documentation to replace the use of this flag
27384 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27387 2005-03-15 Thomas Quinot <quinot@adacore.com>
27389 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27390 here from exp_attr so it can be shared between exp_attr and exp_dist.
27391 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27392 all TSS names, not a subset thereof, and the previous name introduced
27393 an unnecessarily confusion that a distinction might exist between
27394 "OK" TSS names and some "not OK" TSS names.
27396 2005-03-15 Doug Rupp <rupp@adacore.com>
27398 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27401 2005-03-15 Pascal Obry <obry@adacore.com>
27402 Eric Botcazou <ebotcazou@adacore.com>
27406 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27407 when IN_RTS. This is to work around a bootstrap path problem.
27409 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27410 table and pass it to __gnat_install_SEH_handler().
27411 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27413 * lang.opt: Fix specification of -fRTS=.
27415 2005-03-15 Doug Rupp <rupp@adacore.com>
27416 Bernard Banner <banner@adacore.com>
27417 Vincent Celier <celier@adacore.com>
27418 Arnaud Charlet <charlet@adacore.com>
27421 This change works fine when gnatlib is built from the gcc directory,
27422 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27423 is not passed to ada/Makefile.in, so more work is needed by a
27424 Makefile/configure expert.
27426 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27427 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27428 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27430 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27431 Run ranlib on libgccprefix.a
27432 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27433 (ADA_INCLUDE_SRCS): Split Ada packages.
27435 2005-03-15 Robert Dewar <dewar@adacore.com>
27437 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27439 * impunit.adb: Add GNAT.UTF_32
27441 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27443 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27444 now uses GNAT.UTF_32).
27446 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27447 capabilities for categorizing characters using Unicode categories
27449 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27451 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27452 instantiation that has been rewritten as a package body, retrieve spec
27453 to generate proper name for implicit_with_clause.
27454 (Install_Parents): Recognize a parent that is an instantiation but has
27455 been rewritten as a package declaration during analysis.
27457 2005-03-15 Javier Miranda <miranda@adacore.com>
27458 Ed Schonberg <schonberg@adacore.com>
27460 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27461 parameter reported some error we immediately return. This improves the
27462 behaviour of the frontend in case of errors.
27463 (Install_Parent, Remove_Parent): Introduce new flag
27464 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27465 ancestor of a generic child unit, when the child is being instantiated.
27466 (Inline_Instance_Body): If we are compiling the private
27467 part or the body of a child unit, restore the proper visibility of the
27468 parents after compiling the instance body.
27470 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27471 Javier Miranda <miranda@adacore.com>
27474 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27475 of a private type, in which case it is underlying_type that denotes
27476 the proper task. Also modified to use the new entity attribute
27477 that is directly available in the task type and task subtype entities
27478 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27479 arrays when other dimensions than the first are constrained by
27480 discriminants of an enclosing record.
27481 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27482 a combination of indexed and selected components, find ultimate entity
27483 and generate the appropriate reference for it, to suppress spurious
27485 (Note_Possible_Modification): If an entity name has no entity, return.
27486 (Is_Variable): A function call never denotes a variable.
27487 (Requires_Transient_Scope): For record types, recurse only on
27488 components, not on internal subtypes that may have been generated for
27489 constrained components.
27491 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27493 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27494 Eliminated as candidates for resolution. Both efficient, and avoids
27495 anomalies with operators declared in deleted code.
27496 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27497 expansion is disabled (as when compiling a generic) to prevent spurious
27498 warnings on prefixes of selected components.
27500 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27502 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27503 attached to a list before checking whether it appears in the private
27504 declarations of the current package.
27505 (Make_Inequality_Operator): Insert declaration in proper declarative
27506 list rather than just setting the Parent field, so that
27507 Is_Private_Declaration can handle it properly.
27509 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27511 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27512 a renaming a body, check that the renamed subprogram in not intrinsic.
27513 (Find_Direct_Name): If several use_visible entities hide
27514 each other, and the context is a predefined file compiled through
27515 rtsfind, keep only the entity that comes from a predefined file.
27517 2005-03-15 Geert Bosch <bosch@adacore.com>
27519 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27520 long float padding to also cover AMD64 and IA64.
27522 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27524 * s-imgwch.adb: Add with and use of Interfaces.
27525 (Img_Wide_Character): Change type of Val to Unsigned_16.
27526 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27528 2005-03-15 Matthew Gingell <gingell@adacore.com>

27574 Sergey Rybin <rybin@adacore.com>
27576 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
27577 too specific and long-winded to be appropriate for the GNAT User's
27579 Warn about use of GCC switches not documented in the GNAT User's Guide,
27580 as these may cause generated code to not conform to Ada semantics.
27581 Remove mention of -gdwarf-2 for sparc64, since this is now the default.

27847 (Resolve_Slice): If the prefix is an access to an unconstrained array,
27848 compute the actual subtype of the designated object to impose the proper
27850 (Resolve_Selected_Component): Do not insert an access check if the
27851 prefix is an access type: such a node is expanded into an explicit
27852 dereference, on which the access check is performed anyway. Removes
27853 expensive duplicate checks.
27854 (Resolve_Call): Use new flag Is_Obsolescent and field
27855 Obsolescent_Warning so that pragma Obsolescent works on library
27857 Add support for wide wide character type
27858 (Resolve_Allocator): Replace the error message on wrong null-exclusion
27859 value by a warning message.
27860 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
27861 as fixed-point, and one of the operands is non-static and universal, it
27862 can only be an illegal exponentiation operation, in which case there is
27863 no real value to retrieve.
27865 * exp_strm.adb: Add support for wide wide character type
27866 (Build_Elementary_Input_Call): Compute the size of the stream element by

27906 (Unit_Declaration_Node): Ditto.
27907 (Is_Variable_Prefix): For the case of an indexed component whose prefix
27908 has a packed array type, the prefix has been rewritten into a type
27909 conversion. Determine variable-ness from the converted expression.

27914 * stringt.ads, stringt.adb: Handle full UTF-32 range.
27915 Remove ["0A"] from comment, since it can look like a line terminator.
27916 Currently we don't permit this, but this is under discussion by the
27917 ARG, and it is easy enough to use a different example.
27919 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
27920 handling UTF-32 encoding for wide wide character.

27971 pointer to the base of the dispatch table.
27972 Minor changes to comments.
27973 (Controlling_Type): New function for determining the tagged type
27974 associated with a tagged primitive subprogram.
27975 (Expand_Dispatching_Call): Add support for a controlling actual that is

27979 describing the new layout.
27980 (Dispatch_Table): The expander computes the actual array size, allocates
27981 the Dispatch_Table record accordingly, and generates code that displaces
27982 the base of the record after the Typeinfo_Ptr component. The access to
27983 these components is done by means of local functions.
27984 (Offset_To_Top): New function.
27985 (Typeinfo_Ptr): New function.
27986 (Get_TSD): Modified to access the new position of the TSD.

27997 N_Formal_Subtype_Declaration (which is now a subtype).
27998 (Analyze_Formal_Subprogram): Add handling for
27999 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28000 dispatching, setting the controlling status of the formal parameters
28001 and result, and issuing an error if there is no controlling type for
28002 the formal subprogram.
28003 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28004 which is an unclean use of that field, we set the new field
28005 Corresponding_Formal_Spec to make the formal subprogram available to

28007 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28008 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type

28013 abstract formal subprograms in error check for functions returning
28014 abstract types. Set scope of new designator for

28017 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28018 subprogram only if inner one comes from source.
28019 (Analyze_Function_Call): If the call is given in object notation, the
28020 analysis of the name rewrites the node and analyzes it with the proper
28021 argument list. After analyzing the name, if the call has been rewritten
28022 and the result type is set, no further analysis is needed.
28023 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28024 mark in function specification, in a context where the formals are
28025 visible and hide outer homographs.
28027 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28028 as the tagged type for the cases of abstract formal subprograms and
28029 renamings of those. Clean up spec comments.
28030 (Check_Dispatching_Context): Add error message to indicate "abstract
28031 procedure", covering the case of a call to a formal abstract procedure
28032 that has statically tagged operands.
28033 (Check_Dispatching_Call): Check for the case of an actual given by
28034 a tag-indeterminate function call whose type is an ancestor of the
28035 containing call's associated tagged type. This situation can occur
28036 for inherited primitives with function defaults. In this case we
28037 use the tagged type's tag directly as the controlling argument for
28039 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28041 * sprint.adb (Sprint_Node_Actual): Split
28042 N_Formal_Subprogram_Declaration into two alternatives for the new

28118 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28119 on the field if Pragma Component_Alignment (Storage_Unit).
28120 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28121 side-effects as if it were a constant; also make SAVE_EXPR to protect

28141 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28142 component of an array of arrays in an assignment context, and the
28143 aggregate has component associations that require sliding on
28144 assignment, force reanalysis of the aggregate to generate a temporary
28145 before the assignment.
28146 (Must_Slide): Make global to the package, for use in Gen_Assign.
28148 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28150 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28151 unchecked union with no inferable discriminants, return a
28152 Raise_Program_Error node, rather than inserting it at the point the
28154 (Expand_Record_Equality, Component_Equality): Handle properly the case
28155 where some subcomponent is an unchecked union whose generated equality

28164 Arnaud Charlet <charlet@adacore.com>
28166 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28167 address of the exception registration. The Win32 version of this
28168 routine calls __gnat_install_SEH_handler() to initialize the SEH
28169 (Structured Exception Handling) handler.
28170 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28171 SEH (Structured Exception Handling) now.
28172 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28173 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28174 preprocessor condition protecting the call to the extra eh setup
28175 subprogram, which is only available for the ppc target.

28189 Update copyright notice.
28191 * s-tassta.adb (Task_Wrapper): Declare the exception registration

28221 2005-02-09 Vincent Celier <celier@adacore.com>
28223 * prj-makr.adb (Process_Directory): Put file name in canonical case
28224 before matching against the patterns.
28225 If gnatname has been invoked as <prefix>-gnatname
28226 then invoke the compiler as <prefix>-gcc, not just "gcc".
28228 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28230 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28231 with expansion disabled. The actual subtype is needed among other
28232 places when the selected component appears in the context of a loop
28233 bound, and denotes a packed array.
28234 (Operator_Check): Always use the first subtype in the
28235 error message, to avoid the appearance of internal base types.
28236 (Transform_Object_Operation): Copy each actual in full
28237 to the parameter associations of the constructed call, rather than
28238 using the shallow copy mechanism of New_Copy_List. This ensures that
28239 the chaining of named associations is done properly.
28240 (Complete_Object_Operation): Rewrite node, rather than
28241 replacing it, so that we can trace back to the original selected
28244 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28245 and calls that use object notation, if the called function is not
28246 declared in a withed unit, place the elaboration constraint on the
28247 unit in the context that makes the function accessible.
28248 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28249 imposes an elaboration constraint between two packages.
28251 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28253 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28254 views of a private type after handling its private dependents, to
28255 maintain proper stack discipline between entry and exit from the

28271 recursion warnings when compiled with -gnatdm.
28273 2005-02-09 Robert Dewar <dewar@adacore.com>
28275 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28276 Slight fix to documentation of -gnaty with no parameters
28278 * xr_tabls.ads: Add ??? comment for missing overall comment
28280 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28281 we now use by default.
28283 * xsnames.adb: Adjust end of file test to look for five space followed
28284 by '#' instead of six spaces. The format of xsnames.adb was modified
28285 in the last update.
28287 * a-numeri.ads: Add reference to AI-388 for greek letter pi

29034 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29035 with an implicit dereference as its prefix, use
29036 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29038 prefix is generated, if appropriate.
29040 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29041 dereference is rewritten to an explicit one, generate a reference to
29042 the entity denoted by its prefix using the original prefix node, so

29044 access value, if appropriate.
29046 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29047 emitting 'assigned but never read' warning on a variable on the basis

29063 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29064 subprogram which is Imported with convention Intrinsic if an
29065 External_Name argument is specified.
29066 (Process_Import_Or_Interface): Properly diagnose link name argument.

29092 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29093 PCS-specific part of Add_Stub_Type.

29125 the body, to ensure that warnings are properly emitted for each accept
29126 statement of a given task entry.

29162 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29163 is a non-overloaded implicit dereference, call the above subprogram to
29164 ensure proper recording of references.
29166 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29168 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

29229 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29230 internal implementation unit GNAT.Sockets.Thin,

29286 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29288 * gigi.h (others_decl, all_others_decl): New decls representing the
29289 new Others_Value and All_Others_Value objects.
29290 (struct attrib): Rename "arg" component as "args", since GCC expects a
29291 list of arguments in there.
29293 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29294 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29297 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29298 others_decl and all_others_decl instead of hardcoded dummy addresses
29299 to represent "others" and "all others" choices, which is cleaner and
29300 more flexible with respect to the possible eh pointer encoding policies.
29302 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29303 (process_attributes): Account for the naming change of the "args"
29304 attribute list entry component.
29306 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29307 cumulating attributes for different entities into a single list.
29308 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29309 attributes for the current entity and propagate first subtype
29310 attributes to other subtypes.
29311 <E_Procedure>: Attribute arguments are attr->args and not
29312 attr->arg any more.
29313 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29314 argument provided, as this is what GCC expects. Use NULL_TREE instead
29317 2004-11-18 Robert Dewar <dewar@adacore.com>
29319 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
29320 Minor reformatting througout (including new function specs)
29321 Add ??? comments asking for clarification.
29323 2004-11-18 Thomas Quinot <quinot@adacore.com>
29325 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
29326 incomplete duplicate implementation of this subprogram from butil.
29328 2004-11-18 Thomas Quinot <quinot@adacore.com>
29330 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
29331 procedures factors the common processing for building an RPC receiver
29332 for an RCI package or an RACW type.
29333 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
29334 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
29335 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
29337 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
29339 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
29341 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
29342 distribution subprogram identifiers that are either subprogram numbers
29344 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
29345 string distribution identifiers assigned to a given subprogram.
29346 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29347 (Add_RAS_Dereference_TSS): Add comments.
29348 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29349 is not referenced yet because it will be used by the PolyORB DSA
29351 (Insert_Partition_Check): Remove fossile code.
29352 (First_RCI_Subprogram_Id): Document this constant.
29353 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29355 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29356 replaced with calls to Get_Library_Unit_Name_String. Previously there
29357 were several instances of the same code in different locations in the
29358 compiler; this checkin completes the replacement of all of these
29359 instances with calls to a common subprogram.
29360 Minor reformatting.
29362 * sem_dist.adb: Remove comment noting that RPC receiver generation
29363 should be disabled for RACWs that implement RASs.
29364 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
29366 * sem_util.ads, sem_util.adb (Has_Stream): New function
29367 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
29368 qualified name of a library unit into the name buffer.
29369 (Note_Possible_Modification): Generate a reference only
29370 if the context comes from source.
29372 * snames.ads (PCS_Names): New subtype corresponding to names of
29373 supported implementations of the Partition Communication Subsystem
29374 (PCS) (i.e. the runtime library support modules for the distributed
29377 2004-11-18 Robert Dewar <dewar@adacore.com>
29378 Ed Schonberg <schonberg@adacore.com>
29380 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
29381 (Has_Rep_Pragma): New function
29382 (Has_Attribute_Definition_Clause): New function
29383 (Record_Rep_Pragma): Moved here from sem_ch13.adb
29384 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
29386 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
29388 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29389 (Expand_Pragma_Psect_Object): New procedure
29390 These procedures contain the revised and cleaned up processing for
29391 these two pragmas. This processing was formerly in Sem_Prag, but
29392 is more appropriately moved here. The cleanup involves making sure
29393 that the pragmas are properly attached to the tree, and that no
29394 nodes are improperly shared.
29396 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29397 pragmas to Exp_Prag, which is more appropriate.
29398 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29399 check for duplicates Remove use of Is_Psected flag, no longer needed.
29400 Use new Make_String_Literal function with string.
29402 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29403 that are functions return universal values, that have to be converted
29404 to the context type.
29405 Use new Make_String_Literal function with string.
29406 (Get_Stream_Convert_Pragma): New function, replaces the use of
29407 Get_Rep_Pragma, which had to be kludged to work in this case.
29409 * freeze.adb: Use new Has_Rep_Pragma function
29411 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29412 function with string.
29413 Use new Has_Rep_Pragma function.
29415 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29418 2004-11-18 Robert Dewar <dewar@adacore.com>
29420 * errout.ads, errout.adb: (First_Sloc): New function
29422 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29423 check (-gnatyx) instead of being included as a redundant construct
29426 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29427 Style_Check_Order_Subprograms.
29429 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29430 stylesw.adb: Add Style_Check_Xtra_Parens
29432 * usage.adb: Add line for -gnatyx (check extra parens)
29434 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29436 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29437 Robert Dewar <dewar@adacore.com>
29439 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29440 discriminant of a constrained subtype, analyze the copy of the
29441 corresponding constraint, because in some cases it may be only
29442 partially analyzed.
29443 Removes long-lived ??? comments.
29445 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29446 handled controlled or secondary-stack expressions within the
29447 iteration_scheme of a loop.
29449 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29450 bounds that may contain functions calls, to prevent memory leaks when
29451 the bound contains a call to a function that uses the secondary stack.
29452 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29453 generate temporaries for loop bounds that might contain function calls
29454 that require secondary stack and/or finalization actions.
29456 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29457 selected component and the selector is overloadable (not just a
29458 function) treat as function call, Analyze_Call will disambiguate if
29460 (Analyze_Selected_Component): Do not generate an actual subtype for the
29461 selected component if expansion is disabled. The actual subtype is only
29462 needed for constraint checks.
29463 (Analyze_Allocator): If restriction No_Streams is set, then do
29464 not permit objects to be declared of a stream type, or of a
29465 composite type containing a stream.
29467 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29468 No_Streams no longer prohibits with'ing this package.
29470 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29471 discriminants, but the parent base has unknown discriminants, there is
29472 no discriminant constraint to inherit. Such a discrepancy can arise
29473 when the actual for a formal type with unknown discriminants is a
29474 similar private type whose full view has discriminants.
29475 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29476 do not permit objects to be declared of a stream type, or of a
29477 composite type containing a stream.
29479 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29481 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29482 protected operations.
29484 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29485 generated name, it complicates decoding in gdb and hinders debugging
29486 of protected operations.
29487 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29488 flag for the protected entry barrier function.
29489 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29490 flag for the protected entry function.
29492 2004-11-18 Nicolas Setton <setton@adacore.com>
29494 * expect.c: Define __unix__ when __APPLE__ is defined.
29496 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29497 Darwin-specific section.
29499 * lang-specs.h: Change the placement of the %1 marker.
29500 Works around the fact that gcc adds -fPIC by default under Darwin.
29502 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29504 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29505 type of the object with the packed array type, set the Analyzed flag
29506 on the object if it is an entity or simple indexed component, to avoid
29507 spurious type errors.
29509 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29511 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29512 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29513 separate line from the version message.
29515 2004-11-18 Ed Falis <falis@adacore.com>
29517 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29519 (init_float): Eliminate initialization of floating point status for
29520 AE653. The instructions have no effect for vThreads.
29522 2004-11-18 Vincent Celier <celier@adacore.com>
29524 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29525 gnatbind is invoked with -shared.
29527 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29529 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29530 for Detect_Blocking which is redundant with the check done within the
29531 procedure Protected_Single_Entry_Call.
29532 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29533 Detect_Blocking which is redundant with the check done within the
29534 procedure Protected_Single_Entry_Call.
29536 2004-11-18 Vincent Celier <celier@adacore.com>
29538 * makegpr.adb (Compile): Put the compiling switches (in package
29539 Compiler and on the command line) immediately after "-c", instead of
29540 at the end of the command line invocation of the compiler, when
29541 compiling a non-Ada file.
29542 (Build_Global_Archive): When there is no need to rebuild the archive,
29543 set Global_Archive_Exists, so that the archive is passed to the linker
29546 2004-11-18 Robert Dewar <dewar@adacore.com>
29547 Sergey Rybin <rybin@adacore.com>
29550 Remove extra paren check from list of checks for redundant constructs
29551 Add documentation of new -gnatyx style check (check extra parens)
29552 Remove paragraph about gnatelim debug options.
29554 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29555 objects rather than forbidding dependencies on the package Ada.Streams.
29557 * sinfo.ads: Add ??? note that we should document pragmas passed to
29560 * g-expect.ads: Fix a few typos in the comments.
29562 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29564 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29567 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29569 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29571 2004-11-07 Andreas Schwab <schwab@suse.de>
29573 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29575 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29578 * Makefile.in (darwin): Set soext to .dylib.
29580 2004-10-26 Vincent Celier <celier@gnat.com>
29581 Thomas Quinot <quinot@act-europe.fr>
29583 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29584 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29585 there is no use of GNAT.Sockets.Constants.
29586 Remove remaining pragma Import for C_Write
29587 Remove C_Read and C_Write from internal implementation unit
29588 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29589 the read and write functions from the system runtime library is fine
29590 on UNIX but won't work under Windows).
29592 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29593 (Check_Selector): Use C_Recv instead of C_Read.
29594 Selectors are the GNAT.Sockets abstraction to perform a select()
29595 call on a set of descriptors. To allow abortion of an ongoing
29596 select operation, some data is written to a dedicated socket that
29597 is always monitored.
29598 Under Windows, the write and read library functions cannot operate
29599 on sockets, so we need to use send and recv instead, which is portable
29600 across all supported platforms.
29602 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29603 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29604 (using the read and write functions from the system runtime library is
29605 fine on UNIX but won't work under Windows).
29607 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29609 * mlib-tgt-darwin.adb: New file.
29611 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29612 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29613 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29614 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29617 * Makefile.in: Add support for building shared libraries under Darwin.
29618 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29619 the low level EH init subprogram to be called from __gnat_initialize.
29621 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29622 indicates which options to pass to the archive indexer.
29624 * mlib-utl.adb: Add support for calling ranlib with additional
29625 options. This is needed for instance under Mac OS X.
29626 (Ranlib_Options): New global variable, used to store the potential
29627 options to pass to ranlib.
29628 (Ar): Use Ranlib_Options when spawning ranlib.
29629 (Initialize): Set the value of ranlib option.
29631 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29633 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29634 instead of 8K, to reflect the real potential needs for stack-checking
29637 2004-10-26 Pascal Obry <obry@gnat.com>
29639 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29641 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29642 Windows only the initial thread stack size can be set so it is good to
29643 start we a low stack size.
29644 The OS will adjust the size as needed.
29646 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29647 Nicolas Setton <setton@act-europe.fr>
29649 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29650 "__unix__" instead of "unix".
29651 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29652 sections were just mistakenly ignored. The former is
29653 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29654 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29655 of hpux. This prevents an unwanted definition of the symbol
29656 convert_addresses in adaint.o.
29658 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29660 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29661 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29663 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29665 * a-filico.ads, a-filico.adb: fix incorrect header.
29667 2004-10-26 Javier Miranda <miranda@gnat.com>
29669 * a-ststio.ads: Fix typo in identifier
29671 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29673 * sem_ch4.adb: Minor reformatting.
29675 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29677 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29678 enabled, check the result of unary and binary operations when the
29679 expression is the right-hand side of an assignment.
29681 2004-10-26 Vincent Celier <celier@gnat.com>
29683 * clean.adb (Delete): Do not output warnings when in quiet output and
29684 not in verbose mode.
29685 (Force_Deletions): New Boolean flag, defaulted to False
29686 (Delete): Only delete a file if it is writable, and when
29687 Force_Deletions is True.
29688 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29689 (Usage): Line for new switch -f
29690 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29693 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29695 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29696 JM type only if its size matches that of the wrapper. When a size is
29697 prescribed and the field is not aliased, remove the wrapper of a JM
29698 type only if the size is not greater than that of the packed array.
29699 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29702 2004-10-26 Geert Bosch <bosch@gnat.com>
29704 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29705 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29706 (Pred): Implement in terms of Succ.
29708 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29710 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29711 unchecked conversion is safe for in-place use if the expression of the
29712 conversion is safe.
29713 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29714 be expandable in place even if the aggregate does not come from source.
29715 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29716 designated object of an allocator in place, rather than building it
29717 first on the stack. The previous scheme forces a full copy of the array,
29718 and may be altogether unsusable if the size of the array is too large
29719 for stack allocation.
29721 2004-10-26 Robert Dewar <dewar@gnat.com>
29723 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29724 compares if the component is atomic.
29726 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29727 array assignment if the component type is atomic.
29729 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29730 Eric Botcazou <ebotcazou@act-europe.fr>
29732 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29733 is aliased and is a by_reference type, do not pass by copy.
29734 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29735 detect whether the call is in the right side of an assignment or
29736 the expression of an object declaration. Recurse on component
29737 association within aggregates.
29738 Call it in the condition that determines whether the temporary is
29739 necessary for correct stack-checking.
29741 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29743 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29744 RACW_Type, used in the PolyORB version.
29745 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29746 version and the GARLIC version.
29748 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29749 Rename RCI_Info to RCI_Locator for better consistency between the
29750 GARLIC and PolyORB versions of the distributed systems annex.
29751 (DSA_Implementation_Name): This enumeration lists the possible
29752 implementations of the Partition Communication Subsystem for the
29753 Distributed Systems Annex (DSA). The three available implementations
29754 are the dummy stub implementation (No_DSA), and two versions based on
29755 two different distribution runtime libraries: GARLIC and PolyORB. Both
29756 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29758 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29761 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29762 between the GARLIC and PolyORB versions of the distributed systems
29764 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29766 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29768 * gnat1drv.adb: Suppress calling the back end when
29769 Frontend_Layout_On_Target is true.
29771 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29773 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29774 Set_Read_Only): New subprograms.
29775 These new routines allow the user to set or unset the Owner execute
29776 and Owner write permission flags on a file.
29778 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29779 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29781 2004-10-26 Matthew Gingell <gingell@gnat.com>
29783 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29785 2004-10-26 Pascal Obry <obry@gnat.com>
29787 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29788 memory before the faulting page we properly test the process read
29789 access for this address using appropriate Win32 routine.
29790 (HPUX sections): guard with "__hpux__" instead of "hpux".
29792 2004-10-26 Robert Dewar <dewar@gnat.com>
29794 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29795 entry parameter if pragma Unreferenced set, since we do not properly
29796 handle the case of multiple parameters.
29798 2004-10-26 Vincent Celier <celier@gnat.com>
29800 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29801 (Ada_Objects_Path.Add): For a library project, add to the object path
29802 the library directory only if there is no object directory or if the
29803 library directory contains ALI files.
29804 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29806 2004-10-26 Vincent Celier <celier@gnat.com>
29808 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29809 extension of library projects.
29811 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29812 path defaults to ".:<prefix>/lib/gnat".
29813 (Parse): For an extending all project, allow direct import of a project
29814 that is virtually extended.
29816 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29817 the specified name is directly imported, return its ID. Otherwise, if
29818 an extension of this project is imported, return the ID of the
29821 2004-10-26 Robert Dewar <dewar@gnat.com>
29823 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
29824 (Sub3): New procedure, used by Scaled_Divide
29825 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
29826 correct more than one instance of failure to propagate carries
29828 (Double_Divide): Handle overflow case of largest negative number
29829 divided by minus one.
29831 * s-arit64.ads (Double_Divide): Document that overflow can occur in
29832 the case of a quotient value out of range.
29835 2004-10-26 Robert Dewar <dewar@gnat.com>
29837 * s-bitops.adb (Bit_Eq): Remove redundant check.
29839 * s-bitops.ads: Minor comment updates
29840 Change some occurrences of Address to System.Address
29842 * s-carsi8.ads: Fix minor cut-and-paste error in comments
29844 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29846 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
29847 accessibility check to prefix that is a protected operation.
29849 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29851 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
29852 empty, post message on stub.
29854 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29855 Javier Miranda <miranda@gnat.com>
29857 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
29858 current instance appears within a unit that is directly in the context
29860 Used to determine whether the body of the instance should be analyzed
29861 immediately after its spec, to make its subprogram bodies available
29862 for front-end inlining.
29863 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
29864 constraint is not allowed on the component type (AARM 12.5.3(3))
29866 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29868 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
29869 'Storage_Pool): enhance, document & limit detection of non-sharable
29872 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
29874 * s-pooglo.ads: Add more documentation now that this pool is properly
29877 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29879 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
29880 or protected type with discriminants, do not constrain the
29881 corresponding record type if the subtype declaration has no
29882 discriminant constraints. This can be the case in source code, or in
29883 the subtype declaration created to rename an actual type within an
29886 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29888 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
29889 different kind of stub (possibly wrong name for file), do not check
29891 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
29892 includes call to some function that returns an unconstrained type, do
29895 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29897 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
29898 appear in the code for the main unit. Dependencies among units in the
29899 context of the main unit are established when those other units are
29900 compiled. Otherwise spurious elaboration constraints can generate
29901 incorrect elaboration circularities.
29903 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29904 Ed Schonberg <schonberg@gnat.com>
29906 * sem_util.adb (Is_Aliased_View): Defend against the case where this
29907 subprogram is called with a parameter that is not an object name. This
29908 situation arises for some cases of illegal code, which is diagnosed
29909 later, and in this case it is wrong to call Is_Aliased, as that might
29910 cause a compiler crash.
29911 (Explain_Limited_Type): Refine previous fix to include
29912 inherited components of derived types, to provide complete information.
29914 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
29915 is the prival for a protected object.
29916 It is necessary to mark this entity as a variable, in addition to
29917 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
29918 modified to avoid checking the Aliased flag on entities that are not
29919 objects. (Checking that flag for non-objects is erroneous and could
29920 lead to a compiler crash).
29922 2004-10-26 Robert Dewar <dewar@gnat.com>
29924 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
29925 X_Frac = 0.5, then we know that the number X must be positive.
29926 (Succ): Remove the same redundant test, and also fix the primary test
29927 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
29929 (Decompose): Add fuller comments to spec
29931 2004-10-26 Pascal Obry <obry@gnat.com>
29933 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
29934 validity (process must have read access). Set to 0 in all other cases.
29935 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
29936 violation on Win32.
29937 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
29938 segmentation violation.
29940 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29942 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
29943 whose type is a constructed subtype of an aliased object with an
29944 unconstrained nominal subtype, convert the actual to the constructed
29945 subtype before taking its address.
29947 2004-10-26 Vincent Celier <celier@gnat.com>
29949 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
29950 (Is_Path_Name_Case_Sensitive): New function
29952 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
29953 (Base_Name, Simple_Name, Current_Directory, Compose,
29954 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
29957 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29958 Vasiliy Fofanov <fofanov@act-europe.fr>
29959 Vincent Celier <celier@gnat.com>
29961 * gnat_ugn.texi: Generalize "finding memory problems" section into a
29962 "memory management issues" section and document some of the useful
29963 memory pools provided as part of the GNAT library.
29964 Remove "virtual" from declaration of A::method2 in
29965 the simple example of Ada/C++ mixed system.
29966 Library Projects may be virtually extended: their virtual extensions
29967 are not Library Projects.
29968 Added section on extending project hierarchies.
29970 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
29972 * adaint.c (__gnat_get_libraries_from_registry): Cast value
29974 (__gnat_portable_spawn): Remove const.
29976 * mingw32.h (MAXPATHLEN): Check for previous definition.
29978 2004-10-17 Matthias Klose <doko@debian.org>
29980 * gnatvsn.ads: Set gnat library version to 4.0.
29982 2004-10-05 Vincent Celier <celier@gnat.com>
29984 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
29986 2004-10-04 Laurent Guerby <laurent@guerby.net>
29989 * Makefile.in: Define and use RANLIB_FLAGS.
29991 2004-10-04 Pascal Obry <obry@gnat.com>
29993 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
29994 other x86 platforms).
29996 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
29998 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
29999 in general and triggers stack alignment adjustment for thread entry
30000 points on targets where this is necessary.
30002 2004-10-04 Bernard Banner <banner@gnat.com>
30005 * Makefile.in: Add section for powerpc linux
30006 Add variant i-vxwork-x86.ads
30008 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30010 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30012 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30013 table registration calls when need be. Ensures no reference to the crt
30014 ctors symbol are issued in the SJLJ case, which avoids possible
30015 undefined symbol errors in the case of modules to be statically linked
30018 2004-10-04 Javier Miranda <miranda@gnat.com>
30020 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30021 in-line the code corresponding to subprogram Analyze_Actuals. In
30022 addition, analyze the actuals only in case of subprogram call.
30024 2004-10-04 Ed Falis <falis@gnat.com>
30026 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30028 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30030 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30031 in the documentation.
30033 2004-10-04 Robert Dewar <dewar@gnat.com>
30035 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30037 (Analyze_Block_Statement): Add circuitry to detect following dead code
30038 (Check_Unreachable_Code): Handle case of block exit
30040 2004-10-04 Robert Dewar <dewar@gnat.com>
30042 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30043 (XMatchD): Avoid warning for Logic_Error call
30045 2004-10-04 Robert Dewar <dewar@gnat.com>
30047 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30048 consider expressions buried within a procedure actual to be an actual.
30049 This caused some blowups with uses of packed slices within a procedure
30052 2004-10-04 Robert Dewar <dewar@gnat.com>
30054 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30055 longer need to be initialized to zero.
30056 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30057 initialized to zero.
30059 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30060 considered valid, even if the representation is modular. That's correct
30061 now that we no longer initialize packed modular arrays to zero.
30063 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30064 suffixes. These are now documented as the only cases in which the
30065 debugger ignores outer records.
30066 Previously, the spec allowed arbitrary suffixes for this purpose.
30067 Change name of LJM to JM for packed array pad records
30068 Create separate section on packed array handling, and add a whole new
30069 set of comments to this section describing the situation with packed
30070 modular types and justification requirements depending on endianness.
30072 2004-10-04 Robert Dewar <dewar@gnat.com>
30074 * a-except.adb: Add a comment for last change
30076 * einfo.ads: Minor spelling correction in comment
30078 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30080 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30083 * sem_util.ads: Minor comment update
30085 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30087 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30088 Inline_Always when in Configurable_Run_Time mode.
30090 * sem_prag.adb (Process_Convention): If entity is an inherited
30091 subprogram, apply convention to parent subprogram if in same scope.
30092 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30093 when in Configurable_Run_Time mode.
30095 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30097 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30098 class_wide type after component list has been inherited.
30100 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30102 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30103 Denotes_Previous_Actual, to handle properly the case of a private
30104 actual that is also the component type of a subsequent array actual.
30105 The visibility status of the first actual is not affected when the
30106 second is installed.
30107 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30108 make fully recursive the treatment of formals of packages declared
30110 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30111 the above on exit from an instantiation.
30112 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30113 current instantiation which is now complete.
30114 (Analyze_Package_Instantiation): No instantiated body is needed if the
30115 main unit is generic. Efficient, and avoid anomalies when a instance
30116 appears in a package accessed through rtsfind.
30118 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30120 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30121 do not generate a declaration for a temporary if the call is part of a
30122 library-level instantiation.
30124 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30126 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30127 searching for a limited component to flag.
30129 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30130 expansion of Input, to account for the fact that the implicit call
30131 generated by the attribute reference must freeze the user-defined
30132 stream subprogram. This is only relevant to 'Input, because it can
30133 appear in an object declaration, prior to the body of the subprogram.
30135 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30136 expansion can proceed and further errors uncovered.
30137 (Minor clean up): Fix cases of using | instead of \ for continuation
30140 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30142 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30144 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30145 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.

30148 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30149 specified alignment before validating size.
30150 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30151 stripped-down declaration for the type of the inner field when making
30154 * utils.c (finish_record_type): Do not compute the size in units
30155 incrementally. Instead compute it once for the rep clause case.
30156 Use gcc_assert and gcc_unreachable.
30158 2004-10-04 Vincent Celier <celier@gnat.com>
30160 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30162 (Is_Valid_Path_Name): Take '/' as a directory separator.
30164 2004-10-04 Vincent Celier <celier@gnat.com>
30166 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30167 (Extended_Project) only if Extended_Project is defined, to avoid
30169 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30171 (Parse_Single_Project): Ditto.
30173 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30174 Add_To_Project_Path for virtual projects.
30176 2004-10-04 Vincent Celier <celier@gnat.com>
30178 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30179 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30180 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30181 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30182 parameter Options_2.
30184 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30185 Build_Dynamic_Library with an empty Options_2.
30187 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30190 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30191 directory separator, if any.
30192 (Gprmake): Do not allow mains on the command line for library projects.
30193 Do not attempt to link when the project is a library project.
30194 (Library_Opts): New table to store Library_Options.
30195 (Build_Library): If Library_Options is specified, pass these options
30196 when building a shared library.
30198 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30200 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30201 the end of this procedure now that the unlock operation was inserted
30204 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30206 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30207 corresponding to the Preallocated_Stacks flags in System.
30208 (Get_Target_Parameters): Including the processing for
30209 Preallocated_Stacks.
30211 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
30212 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

30220 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30221 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30222 used to signal whether the compiler creates the required stacks and
30223 descriptors for the different tasks (when True) or it is done by the
30224 underlying operating system at run time (when False).
30225 It is initially set to False in all targets.
30227 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30228 if it is supported by the target.
30229 (Make_Task_Create_Call): Pass the stack address if it has been
30230 previously created. Otherwise pass a Null_Address.
30232 * snames.adb: Add _stack.
30234 * snames.ads: Add Name_uStack. Required to allow the expander to
30235 statically allocated task stacks.
30237 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30238 Stack_Address argument.
30239 Check that its value is equal to Null_Address because this target does
30240 not support the static stack allocation.
30242 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30244 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30247 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30249 * exp_dist.adb: Split declaration of asynchronous flag out of
30250 Add_RACW_Read_Attribute.
30251 Minor reformatting for better alignment with PolyORB version.
30252 Store the entity for the asynchronous flag of an RACW, rather than the
30253 expression, in the asynchronous flags table. This will allow this flag
30254 to be used in other subprograms beside Add_RACW_Read_Attribute.
30256 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30258 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30262 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30263 sockets constant MSG_NOSIGNAL (Linux-specific).
30264 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30265 all Send operations.
30266 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30267 from trigerring SIGPIPE.
30268 Rename components to avoid clash with Ada 2005 possible reserved
30270 (Check_Selector): When the select system call returns with an error
30271 condition, propagate Socket_Error to the caller.

30285 Minor reformatting.
30287 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30288 right way of doing things after all.

30294 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30295 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30296 ensures proper handling of types with rep clauses, which might have
30297 their TYPE_SIZE set already.
30299 2004-09-21 Robert Dewar <dewar@gnat.com>
30301 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30302 packed array types in both little- and big-endian cases. This change
30303 ensures that we no longer count on the unused bits being initialized
30304 for such types (and in particular ensures that equality testing will
30305 only read the relevant bits).
30306 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30307 These changes mean that we no longer need to initialize small packed
30309 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30310 optimization to an LJM field as to its parent field.
30312 * ada-tree.h, trans.c, utils.c, utils2.c:

30315 2004-09-20 Jan Hubicka <jh@suse.cz>
30317 * utils.c (gnat_finalize): Remove.
30318 (end_subprog_body): Directly call cgraph_finalize_function;
30319 do not lower the nested functions.
30321 2004-09-20 Robert Dewar <dewar@gnat.com>
30324 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30325 if an address clause is present, since that means that the Import

30335 * ada-tree.def: Use tree_code_class enumeration constants
30336 instead of code letters.

30356 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30357 Convert the result to File_Size.
30359 * prj.ads: (Project_Error): New exception
30361 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30362 Prj.Com, not from Osint.
30363 (Attrs, Package_Attributes): Tables moved to private part of spec
30364 (Add_Attribute, Add_Unknown_Package): Moved to new child package

30367 Prj.Project_Error after call to Fail.
30368 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30369 Fail. Check that package name is not already in use.
30371 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30372 used by tools, not only by the project manager, and to indicate that
30373 exception Prj.Prj_Error may be raised in case of problem.
30374 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30376 (Attrs, Package_Attributes): Table instantiations moved from the body to
30377 the private part to be accessible from Prj.Attr.PM body.
30379 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30380 from new package Prj.Attr.PM.
30381 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30384 * Makefile.in: Add prj-attr-pm.o to gnatmake object list

30432 pragmas recognized by GNAT.
30434 * gnat_rm.texi: Document pragma Detect_Blocking.
30436 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
30437 raise Program_Error if called from a protected operation.
30439 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30440 the protected action nesting level.
30441 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30442 protected action nesting level.
30443 (Unlock): When pragma Detect_Blocking is active decrease the protected
30444 action nesting level.
30446 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30447 Protected_Action_Nesting.
30449 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30450 Common_ATCB record. It contains the dynamic level of protected action
30451 nesting for each task. It is needed for checking whether potentially
30452 blocking operations are called from protected operations.
30453 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30454 Detect_Blocking is active or not in the partition.
30456 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

30490 contains the required machinery for handling that.
30492 * sem_util.ads: Change comment associated to procedure
30493 Check_Potentially_Blocking_Operation.
30494 This procedure does not insert a call for raising the exception because
30495 that is currently done by the run time.
30497 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30499 * init.c: Add the global variable __gl_detect_blocking that indicates
30500 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30501 making the pragma available at run time.
30502 (__gnat_set_globals): Pass and update the detect_blocking parameter.

30509 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30510 DB is found in the ali file. Any unit compiled with pragma
30511 Detect_Blocking active forces its effect in the whole partition.
30513 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30514 Detect_Blocking is active and delay is called from a protected
30517 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30518 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30519 Detect_Blocking is active (0 otherwise).
30520 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30521 as Detect_Blocking parameter if pragma Detect_Blocking is active (0

30526 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30527 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash

30531 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30532 Update API in placeholder implemetation of s-parint to reflect changes
30533 in distribution runtime library.
30535 * sem_ch3.adb (Expand_Derived_Record): Rename to
30536 Expand_Record_Extension.
30538 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30539 primitive operations of potentially distributed object types that have
30540 non-controlling anonymous access formals.
30542 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30544 New implementation of expansion for remote access-to-subprogram types,
30545 based on the RACW infrastructure.
30546 This version of sem_dist is compatible with PolyORB/DSA as well as
30549 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30550 Asynchrronous that applies to a remote access-to-subprogram type, mark
30551 the underlying RACW type as asynchronous.
30553 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30554 __gnat_using_gnu_linker to 1.
30556 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30557 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

30563 * exp_ch3.adb (Expand_Derived_Record): Rename to
30564 Expand_Record_Extension.
30565 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30566 a component declaration must remain attached at that point in the
30567 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30568 It is therefore necessary to take a copy of the expression when building
30569 the corresponding assignment statement in the init proc.
30570 As a side effect, in the case of a derived record type, we now see the
30571 original expression, without any rewriting that could have occurred
30572 during expansion of the ancestor type's init proc, and we do not need
30573 to go back to Original_Node.
30575 * exp_ch3.ads (Expand_Derived_Record): Rename to
30576 Expand_Record_Extension.
30578 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

30581 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
30582 New subprograms. Used to create a proxy tagged object for a remote
30583 subprogram. The proxy object is used as the designated object
30584 for RAS values on the same partition (unless All_Calls_Remote applies).
30585 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30586 System.Partition_Interface.Get_Unique_Remote_Pointer.
30587 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30588 Renamed from Add_RAS_*_Attribute.
30589 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
30591 New implementation of expansion for remote access-to-subprogram types,
30592 based on the RACW infrastructure.
30594 * exp_dist.ads (Copy_Specification): Update comment to note that this
30595 function can copy the specification from either a subprogram
30596 specification or an access-to-subprogram type definition.

30600 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30601 in an instance, between an explicit subprogram an one inherited from a
30602 type derived from an actual.
30604 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30605 add a polling call if the subprogram is to be inlined by the back-end,
30606 to avoid repeated calls with multiple inlinings.
30608 * checks.adb (Apply_Alignment_Check): If the expression in the address
30609 clause is a call whose name is not a static entity (e.g. a dispatching
30610 call), treat as dynamic.

30614 * g-trasym.ads: Minor reformatting
30616 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

30625 2004-09-09 Pascal Obry <obry@gnat.com>
30627 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30628 enable map file generation. Add the right option to generate the map
30629 file if Map_File is set to True.
30631 * gnatdll.adb (Gen_Map_File): New variable.
30632 (Syntax): Add info about new -m (Map_File) option.

30739 consistent treatment of entity references contained within the
30740 enclosed procedure call.
30742 2004-09-01 Vincent Celier <celier@gnat.com>
30744 * bindgen.adb: (Set_EA_Last): New procedure

30776 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
30777 target names rewrite to fix regressions with recent version of

30856 for a global aliased object with a variable size and an unconstrained
30857 nominal subtype, pretend there is no initializer if the one we have is
30858 incomplete, and avoid referencing an inexistant component in there. The
30859 part we have will be rebuilt anyway and the reference may confuse

30883 unit, this is an attempt to inline a construct that is not available in
30884 the current restricted mode, so abort rather than trying to continue.
30886 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
30887 discriminants that rename those of the parent, recover names of
30888 original discriminants for the constraint on the full view of the

30919 returning C.int, to avoid using a derived boolean type.
30921 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
30922 Duplicate_Subexpr_No_Checks in preference to direct use of

30950 ignore overflows on low and high bounds of an index to also account for
30951 differences in signedness between sizetype and gnu_index_subtype.
30952 These are as legitimate as the ones caused by a lower TYPE_PRECISION

33275 * gnat_ugn.texi: Minor change to -gnatS documentation
33277 * sprint.adb: Remove some instances of Assert (False) and for this
33278 purpose replace them by output of a ??? string.
33280 * checks.adb, exp_aggr.adb, sem_elim.adb: Remove useless pragma
33283 * lib-writ.adb, lib-load.adb, lib.ads, lib.adb: Remove Dependent_Unit
33284 flag processing. This was suppressing required dependencies in
33285 No_Run_Time mode and is not needed since the binder does not generate
33286 references for things in libgnat anyway.
33288 * sem_ch3.adb (Access_Type_Declaration): Reorganize code to avoid GCC
33291 2004-05-14 Thomas Quinot <quinot@act-europe.fr>

33305 actions if the object is a renaming.
33307 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
33308 Check_Formal_Package_Instance, to determine more precisely when the
33309 formal and the actual denote the same entity.
33311 2004-05-14 Javier Miranda <miranda@gnat.com>
33313 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
33315 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
33316 corresponding to a private_with must be removed from visibility; it
33317 will be made visible later, just before we analyze the private part of
33319 (Check_Private_Child_Unit): Allow private_with clauses in public
33321 (Install_Siblings): Make visible the private entities of private-withed
33323 (Install_Withed_Unit): Do not install the private withed unit if we
33324 are compiling a package declaration and the Private_With_OK flag was
33325 not set by the caller. These declarations will be installed later,
33326 just before we analyze the private part of the package.
33328 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
33329 during the evaluation of the expression that initializes the object,
33330 decorate it with the expected type to avoid cascade errors.
33333 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
33334 subprogram we have to install the private_with clauses after its
33335 specification has been analyzed (as documented in AI-262.TXT).
33337 * sem_ch8.adb (Has_Private_With): New function. Determines if the
33338 current compilation unit has a private with on a given entity.
33339 (Find_Direct_Name): Detect the Beaujolais problem described in
33342 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
33343 provides the functionality of the function Is_Ancestor that was
33344 previously available in sem_ch10. It has been renamed to avoid
33347 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses

33507 * trans.c (gnat_stabilize_reference_1): Remove case 'b'.
33509 2004-05-13 Diego Novillo <dnovillo@redhat.com>
33511 Merge from tree-ssa-20020619-branch.
33513 * config-lang.in (boot_language, build_by_default): Set
33515 * utils.c (unchecked_convert): Use OEP_ONLY_CONST.
33516 (max_size): Add static chain op for call_expr.
33518 2004-05-12 Richard Sandiford <rsandifo@redhat.com>

33523 2004-05-11 Roger Sayle <roger@eyesopen.com>
33525 * utils.c (max_size): Use MIN_EXPR to find the minimum value of a
33528 2004-05-10 Doug Rupp <rupp@gnat.com>
33530 * 5qsystem.ads: Remove Short_Address subtype declaration. Moved to
33533 * s-auxdec.ads: Add Short_Address subtype (moved here from System).
33535 * Makefile.in: [VMS]: Add translation for 5qauxdec.ads.
33537 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
33538 Fixes undefined symbols in IA64 gnatlib.
33540 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
33542 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
33543 Short_Address). This will be moved to system.auxdec.
33545 2004-05-10 Thomas Quinot <quinot@act-europe.fr>
33547 * sem_util.adb: Replace test for presence of a node that is always
33548 present with a call to Discard_Node.
33550 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
33551 Analyze on the library unit node after generation of distribution stub
33552 constructs. The call was a no-op because Unit_Node has already been
33553 Analyzed, and the tree fragments for the distribution stubs are
33554 analyzed as they are inserted in Exp_Dist.
33555 Update comment regarding to distribution stubs to reflect that we
33556 do not generate stub in separate files anymore.
33558 * einfo.ads: Clarify the fact that a tagged private type has the
33559 E_Record_Type_With_Private Ekind.
33561 * erroutc.adb: Minor reformatting

34870 of inlined call has been improved to preserve a consistent assignment

35165 2004-03-29 GNAT Script <nobody@gnat.com>
35167 * Make-lang.in: Makefile automatically updated
35169 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
35171 * memtrack.adb: Log realloc calls, which are treated as free followed
35174 2004-03-25 Vincent Celier <celier@gnat.com>
35176 * prj-makr.adb (Process_Directories): Detect when a file contains
35177 several units. Do not include such files in the config pragmas or
35178 in the naming scheme.

35186 resolve links when computing the display names.
35188 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35190 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35191 attribute reference does not denote a subtype, it can be any
35192 expression that has a classwide type, potentially after an implicit
35193 dereference. In particular, the prefix can be a view conversion for
35194 a classwide type (for which Is_Object_Reference holds), but it can
35195 also be a value conversion for an access-to-classwide type. In the
35196 latter case, there is an implicit dereference, and the original node
35197 for the prefix does not verify Is_Object_Reference.
35199 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35200 conversion of a discriminant-dependent component of a mutable object
35203 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35205 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35206 inherited, has convention C, and has unconstrained array parameters,
35207 place the corresponding warning on the derived type declaration rather
35208 than the original subprogram.
35210 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35211 indication on renaming declaration, if formal has a box and actual
35214 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35215 determine whether to generate an implicit or explicit reference to
35216 the renamed entity.
35218 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35219 subprogram renaming comes from a defaulted formal subprogram in an
35222 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35224 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35225 value expressions to ensure that calls within a component definition
35226 will be checked (since those are evaluated during the record type's
35229 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
35231 * s-tpobop.adb: Code clean up:
35232 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

35242 * decl.c (gnat_to_gnu_entity, case E_Access_Type): Pass value
35243 of No_Strict_Aliasing to build_pointer_type_for_mode.
35244 * utils.c (update_pointer_to): Walk pointer and ref chains.
35246 2004-03-22 Cyrille Comar <comar@act-europe.fr>
35248 * ali.ads: Fix Comment about Dynamic_Elab.
35250 * gnatls.adb (Output_Unit): Add output of many flags (Dynamic_Elab,
35251 Has_RACW, Is_Generic, etc.)
35252 (Output_Object, Gnatls): Take into account ALI files not attached to
35255 2004-03-22 Vincent Celier <celier@gnat.com>
35257 * gprep.adb: Change all String_Access to Name_Id
35258 (Is_ASCII_Letter): new function
35259 (Double_File_Name_Buffer): New procedure
35260 (Preprocess_Infile_Name): New procedure
35261 (Process_Files): New procedure
35262 (Gnatprep): Check if output and input are existing directories.
35263 Call Process_Files to do the real job.
35265 2004-03-22 Robert Dewar <dewar@gnat.com>
35267 * prj-env.adb, prj-nmsc.ads, prj-proc.ads,

35270 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
35272 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
35273 case when the source contains only comments.
35275 2004-03-22 Ed Schonberg <schonberg@gnat.com>
35277 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35278 declaration for a child subprogram body that acts as a spec, indicate
35279 that the entity in the declaration needs debugging information.
35281 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35282 full view if the subtype is created for a constrained record component;
35283 gigi has enough information to construct the record, and there is no
35284 place in the tree for the declaration.
35286 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35287 serial number for the dummy body that is built for analysis, to avoid
35288 inconsistencies in the generation of internal names when compiling
35291 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35293 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35296 2004-03-22 GNAT Script <nobody@gnat.com>
35298 * Make-lang.in: Makefile automatically updated
35300 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35302 * decl.c (gnat_to_gnu_entity): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
35303 * trans.c (tree_transform, emit_index_check): Likewise.
35304 * utils.c (build_template): Likewise.
35305 (max_size, convert): Remove handling of WITH_RECORD_EXPR.
35306 (maybe_unconstrained_array, unchecked_convert): Likewise.
35307 * utils2.c (gnat_truthvalue_conversion, build_binary_op): Likewise.
35308 (build_unary_op): Likewise.
35309 (compare_arrays, build_allocator): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.

35318 * gnat_ug.texi: Add info directory category and entry.
35319 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
35320 gnat_ug_wnt.texi: Regenerate.
35322 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
35324 * ada-tree.h: Update copyright notice.
35325 Minor reformatting.
35327 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35329 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35330 as regular exception objects and not as mere integers representing the
35331 condition code. The latter approach required some dynamics to mask off
35332 severity bits, which did not fit well into the GCC table based model.
35333 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35334 exception data objects. We don't it and it would conflict with the other
35335 external symbol we have to generate for such exceptions.
35337 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35338 the special code for VMS exceptions, since these are now represented
35339 as regular exceptions objects.
35341 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35343 * decl.c (debug_no_type_hash): Remove.
35344 (gnat_to_gnu_entity, case E_Array_Type): Don't set and clear it.
35345 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
35347 2004-03-19 Laurent Guerby <laurent@guerby.net>
35349 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35350 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35352 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35354 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35355 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35356 (TYPE_RM_SIZE_INT): Directly use type.values.
35357 (TREE_LOOP_ID): Clean up check.
35358 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35359 TYPE_VALUES, not TYPE_FIELDS.
35360 * trans.c (convert_with_check): Delay access of bounds of basetype
35361 until sure is numeric.
35363 2004-03-18 Arnaud Charlet <charlet@act-europe.fr>

35368 * 5ataprop.adb, 5ftaprop.adb, 5htaprop.adb, 5itaprop.adb, 5staprop.adb,
35369 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
35370 Specific.Set instead of direct call to e.g pthread_setspecific.
35372 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35374 * adaint.c: Update comments.
35376 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35377 GNATLIB_SHARED for FreeBSD.
35379 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35381 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35382 When needed (stack checking) the stack size is retrieved
35383 from the VxWorks kernel.
35385 * Makefile.in: Flag -nostdinc is required when building the run time
35386 for avoiding looking for files in the base compiler.
35387 Add the VxWorks specific version of the package body for
35388 System.Stack_checking.Operations (5zstchop.adb).
35390 * Make-lang.in: Add the object file for
35391 System.Stack_Checking.Operations.
35393 * Makefile.rtl: Add object file for the package
35394 System.Stack_Checking.Operations.
35396 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
35398 * s-stache.ads, s-stache.adb: Move the operations related to stack
35399 checking from this package to package System.Stack_Checking.Operations.
35400 This way, stack checking operations are only linked in the final
35401 executable when using the -fstack-check flag.
35403 2004-03-18 Doug Rupp <rupp@gnat.com>
35405 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
35408 * 5qsystem.ads, 5xcrtl.ads: New files.

35415 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35416 the procedures Add_To_Path_File.
35417 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35418 making sure that each directory is present only once and, for object
35419 dirs, when a directory already present is added, the duplicate is
35420 removed and the directory is always put as the last in the table.
35421 Write the path files at the end of these accumulations.
35423 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35424 Files_Htable for all sources.
35426 * prj-proc.adb (Process): Remove restrictions between not directly
35427 related extending projects.

35432 (Find_Sources): Minor speed optimization.
35434 * prj-proc.ads, prj-proc.adb (Check, Recursive_Check, Process): New
35435 parameter Trusted_Mode.
35437 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35439 * scn.adb (Determine_License): Take into account a degenerated case
35440 when the source contains only comments.
35442 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35444 * sem_warn.adb (Check_References): For a warning on a selected
35445 component that does not come from source, locate an uninitialized
35446 component of the record type to produce a more precise error message.
35448 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35450 * 3zsoccon.ads: Fix multicast options.
35452 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35455 2004-03-15 Robert Dewar <dewar@gnat.com>
35457 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
35458 pragma used for a private type.
35460 * lib-xref.adb (Generate_Reference): Do not generate warning if
35461 reference is in a different unit from the pragma Unreferenced.
35463 * 5vtpopde.adb: Minor reformatting
35464 Fix casing of To_Task_ID
35466 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35467 flag if we have an unchecked conversion to an access type in the same
35470 2004-03-15 Geert Bosch <bosch@gnat.com>
35472 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35473 imaginary parts, use Double precision throughout.
35475 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35476 we want to be able to compile run-time with -gnata for testing, but
35477 this may also be instantiated in user code that is compiled with -gnata.
35479 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35481 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35482 codes. Having a separate type for this is useful to enforce consistency
35483 throughout the various run-time units.
35484 (Exception_Data): Use Exception_Code for Import_Code.
35486 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
35487 Natural and Integer in various places.
35488 (Register_VMS_Exception): Use Base_Code_In to compute the exception code
35489 with the severity bits masked off.
35490 (Register_VMS_Exception): Handle the additional exception data pointer
35493 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
35494 component, now reflected by an exported accessor.
35495 (is_handled_by): New routine to compute whether the propagated
35496 occurrence matches some handler choice specification. Extracted out of
35497 get_action_description_for, and expanded to take care of the VMS
35499 (get_action_description_for): Use is_handled_by instead of an explicit
35500 complex condition to decide if the current choice at hand catches the
35501 propagated occurrence.
35503 * raise.h (Exception_Code): New type for C.
35505 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35506 System.Standard_Library.Exception_Code, to allow references from the
35507 pragma import/export expander.
35509 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35510 New accessors to allow easy access to GNAT exception data
35512 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35513 redundant Handled_By_Others component, helper for the personality
35514 routine which will now be able to call the appropriate exception data
35517 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35518 component of Standard_Exception_Type to be the closest possible to
35519 Exception_Code in System.Standard_Library, that we cannot get at this
35520 point. Expand a ??? comment to notify that this type node should
35521 probably be rewritten later on.
35523 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35524 registration call to include a pointer to the exception object in the
35527 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35528 instead of int and explicit bitmasks.
35530 2004-03-15 Vincent Celier <celier@gnat.com>
35532 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35533 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35535 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35536 longer needed now that it is in the spec of
35537 System.Tasking.Task_Attributes.
35539 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35541 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35543 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35545 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35546 taken care of in Scan_Make_Arg.
35547 (Scan_Make_Arg): Add the executable suffix only if the argument
35548 following -o, in canonical case, does not end with the executable
35549 suffix. When in verbose mode and executable file name does not end
35550 with executable suffix, output the executable name, in canonical case.
35552 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35553 to avoid warnings when instantiating Ada.Task_Attributes.
35556 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35557 in the correct order.
35559 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
35560 redirect standard output and error to a file for the invocation of the
35561 compiler, then read the file.
35563 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
35564 directory, instead of the Value.
35565 (Find_Source_Dirs): Remove useless code & comments.
35567 2004-03-15 Ed Schonberg <schonberg@gnat.com>
35569 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35570 tagged type is inherited, and the parent operation is not frozen yet,
35571 force generation of a freeze node for the inherited operation, so the
35572 corresponding dispatch entry is properly initialized.
35573 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35574 when looking for user-defined equality operation.
35576 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35577 boolean when locating primitive equality of tagged component.
35579 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
35580 bit-aligned field and the right-hand side a string literal, introduce
35581 a temporary before expanding assignment into a loop.
35583 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35584 priority in full, to ensure that any expanded subepxressions of it are
35585 elaborated in the scope of the init_proc.
35587 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
35588 after object declaration, skipping over code that may have been
35589 generated for validity checks.
35591 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
35592 discriminants, ignore the known discriminants of its full view, if
35593 any, to check legality.
35595 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
35596 component if type has unknown discriminants.
35597 (Analyze_Private_Extension_Declaration): Discriminant constraint is
35598 null if type has unknown discriminants.
35600 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
35601 for end label when present.
35603 * s-fileio.adb (Open): When called with a C_Stream, use given name for
35604 temporary file, rather than an empty string.
35606 2004-03-15 Ed Falis <falis@gnat.com>
35608 * s-thread.adb: Removed, no longer used.
35610 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35612 * decl.c (target.h): Now include.
35613 (gnat_to_gnu_entity, case E_Access_Type): Use mode derived from ESIZE

35628 * 5ztpopsp.adb, 56tpopsp.adb: Fix spelling of Task_ID.
35630 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
35631 Insert_Dereference_Action when rewriting an implicit dereference into
35632 an explicit one, this will be taken care of during expansion of the
35633 explicit dereference.
35634 (Expand_N_Slice): Same. Always do the rewriting, even for the case
35635 of non-packed slices, since the dereference action generated by
35636 expansion of the explicit dereference is needed in any case.
35637 (Expand_N_Selected_Component): When rewriting an implicit dereference,
35638 analyze and resolve the rewritten explicit dereference so it is seen
35640 (Insert_Dereference_Action): This procedure is now called only for the
35641 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
35642 dereferences that do not come from source (including explicit
35643 dereferences resulting from rewriting implicit ones), but do not
35644 recursively insert a check for the dereference nodes contained within
35646 (Insert_Dereference_Action): Clarify and correct comment.
35648 2004-03-08 Paolo Bonzini <bonzini@gnu.org>

35658 * a-tags.adb, a-tags.ads, s-finimp.adb, s-finroo.ads,
35659 i-cpoint.ads, i-cpoint.adb, i-cstrin.adb, i-cstrin.ads,
35660 5iosinte.ads, 5sosinte.ads, 5staspri.ads, 5itaprop.adb,
35661 5staprop.adb, 5wtaprop.adb, s-tataat.ads, s-tataat.adb: Move
35662 unchecked conversion to spec to avoid warnings.
35664 * s-tasini.adb, s-taskin.ads, 5atpopsp.adb: Correct spelling Task_Id
35667 * 7stpopsp.adb: Correct casing in To_Task_ID call
35669 * a-strsea.ads, a-strsea.adb: Minor reformatting
35671 * einfo.ads, einfo.adb: Define new flag No_Strict_Aliasing

36523 checks for bitfield creation are triggered.
36524 (finish_record_type): During last pass over the fields, clear
36525 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

36984 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
36985 N_String_Literal node always references an E_String_Literal_Subtype
36986 entity. This may not be true in the future.
36987 (Possible_Bit_Aligned_Component): Move processing of
36988 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
36990 * exp_ch6.adb (Expand_Thread_Body): Pick up

36995 (Type_May_Have_Bit_Aligned_Components): New function.

37035 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37036 ineffective elaborate all pragmas on non-visible packages (this
37037 happened when a renamed subprogram was called). Now the elaborate all
37038 always goes on the package containing the renaming rather than the one
37039 containing the renamed subprogram.
37041 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37042 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37067 * make.adb (Gnatmake): Special process for files to compile/check when
37068 -B is specified. Fail when there are only foreign mains in attribute
37069 Main of the project file and -B is not specified. Do not skip bind/link

37101 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37103 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37104 all attributes, including read-only attribute.

37109 library naming scheme.

37140 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37141 protected objects when allocator has a subtype indication, not a

37143 checked when limited aggregates are implemented.

37146 pure, emit warning.

37292 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
37293 Minor reformatting throughout
37295 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37297 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37298 bounds of a loop, create a separate block in order to generate proper
37299 cleanup actions to prevent memory leaks.
37301 * sem_res.adb (Resolve_Call): After a call to
37302 Establish_Transient_Scope, the call may be rewritten and relocated, in
37303 which case no further processing is needed.
37305 * sem_util.adb: (Wrong_Type): Refine previous fix.
37306 Fixes ACATS regressions.
37309 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
37312 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
37314 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
37315 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
37318 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37321 2003-12-08 Robert Dewar <dewar@gnat.com>
37323 * 7sintman.adb: Minor reformatting
37325 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37326 standard linker options to get standard libraries linked. We now plan
37327 to provide dummy versions of these libraries to match the appropriate
37328 configurable run-time (e.g. if a library is not needed at all, provide
37329 a dummy empty library).
37331 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37332 options (-L parameters and standard libraries). What we plan to do is
37333 to provide dummy libraries where the libraries are not required.
37335 * gnatbind.adb: Minor comment improvement
37337 2003-12-08 Javier Miranda <miranda@gnat.com>
37339 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37340 aggregate in the parent. Otherwise constants with limited aggregates
37341 are not supported. Add new formal to pass the component type (Ctype).
37342 It is required to call the corresponding IP subprogram in case of
37343 default initialized components.
37344 (Gen_Assign): In case of default-initialized component, generate a
37345 call to the IP subprogram associated with the component.
37346 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37347 of aggregate with default initialized components.
37348 (Has_Default_Init_Comps): Improve implementation to recursively check
37349 all the present expressions.
37351 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37352 to indicate that the initialization call corresponds to a
37353 default-initialized component of an aggregate.
37354 In case of default initialized aggregate with tasks this parameter is
37355 used to generate a null string (this is just a workaround that must be
37356 improved later). In case of discriminants, this parameter is used to
37357 generate a selected component node that gives access to the discriminant
37360 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37361 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37362 allocated aggregates with default-initialized components.
37364 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37365 the box notation is used in positional aggregates.

37407 Process nodes N_Comment.
37409 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37410 without comments and there are some comments, set the flag
37411 Unkept_Comments to True.
37412 (Scan): If there are comments, set the flag Unkept_Comments to True and
37413 clear the comments.
37414 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment

37443 Comment_Id and set Token to Tok_Comment when scanning a comment.
37444 (Set_Comment_As_Token): New procedure
37446 * sinput-p.adb: Update Copyright notice
37447 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
37448 that no longer exists.
37450 2003-12-08 Javier Miranda <miranda@gnat.com>
37452 * sem_aggr.adb: Add dependence on Exp_Tss package
37453 Correct typo in comment
37454 (Resolve_Aggregate): In case of array aggregates set the estimated
37455 type of the aggregate before calling resolve. This is needed to know
37456 the name of the corresponding IP in case of limited array aggregates.
37457 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37458 in case of default initialized array components.
37460 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

37478 2003-12-08 Arnaud Charlet <charlet@act-europe.fr>
37480 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
37481 they are automatically generated by Make-lang.in and cause nothing but
37482 maintenance troubles.
37484 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
37486 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

37500 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
37501 to ensure that the kernel fills in the interrupted context structure
37502 before calling a signal handler, which is necessary to be able to
37503 unwind past it. Update the copyright notice.
37505 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37507 * a-elchha.ads: New file.
37509 * a-elchha.adb: New default last chance handler. Contents taken from
37510 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.
37512 * a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine
37513 is moved to a-elchha.adb to provide a target-independent default last

37592 included in HIE_NONE_TARGET_PAIRS.
37594 2003-12-03 Ed Schonberg <schonberg@gnat.com>
37597 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
37598 is legal in an instance, because legality is cheched in the template.

37619 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
37620 so that the debugger can reliably access the value of the parameter,

37755 between signals and interrupts.
37756 Add to Unblocked_Signal_Mask the set of signals that are in
37760 Adding a check to see whether the Interrupt_ID we want to unmask is in
37761 the range of Keep_Unmasked (in procedure Interrupt_Self_Process). The
37762 reason is that the index type of the Keep_Unmasked array is not always
37763 Interrupt_ID; it may be a subtype of Interrupt_ID.
37765 2003-11-24 Gary Dismukes <dismukes@gnat.com>
37768 (Remove_Side_Effects): Condition constantness of object created for a

37810 2003-11-24 Sergey Rybin <rybin@act-europe.fr>
37812 * opt.adb (Tree_Write): Gnat_Version_String is now a function, so we
37813 can not use it as before (that is, as a variable) when dumping it into
37814 the tree file. Add a local variable to store the result of this
37815 function and to be used as the string to be written into the tree.

40524 xtreeprs.adb: Correct statements in comments about maintainership
40527 2002-09-23 Zack Weinberg <zack@codesourcery.com>
40529 * Make-lang.in (EXTRA_GNATBIND_OBJS): Add version.o.
40530 * Makefile.in (TOOLS_LIBS): Add ../../version.o.
40531 * gnatvsn.ads: Gnat_Version_String is now a function.

40535 gnatls.adb,gnatmake.adb, gnatprep.adb, gnatpsta.adb:
40536 Remove pragma Ident (Gnat_Version_String). If this was the
40537 sole use of package Gnatvsn, remove the with statement too.
40538 * gnat1drv.adb: Tweak -gnatv output.
40540 2002-09-17 Richard Henderson <rth@redhat.com>
40542 * trans.c (tree_transform): Use real_ldexp not REAL_VALUE_LDEXP.

41190 function call could reallocate the table which was being indexed
41191 using its result). Fixes ada/4851.

41558 2001-12-17 Laurent Pautet <pautet@gnat.com>
41561 Fix comment of Shutdown_Socket and Close_Socket. These functions
41562 should not fail silently because if they are called twice, this
41563 probably means that there is a race condition in the user program.
41564 Anyway, this behaviour is consistent with the rest of this unit.
41565 When an error occurs, an exception is raised with the error message
41566 as exception message.

41719 reference nodes, since this field is used in such nodes.

42901 (Time_Stamp_Mismatch): use CRC_Match for comparison.
42902 (Set_Source_Table): idem.
42905 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
42906 instead of simple checksum.
42907 (CRC_Match): new function.
42908 (CRC_Error): new constant.
42910 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
42911 a CRC now and not a simple checksum. A CRC uses lower-case hex
42912 letters, fixes ambiguity in parsing.
42914 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
42915 is what this variable will store.
42917 * bcheck.adb: Change reference to chechsum in comments by CRC.
42918 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
42919 rename All_Checksum_Match to All_CRC_Match. Change due to API
42920 renaming since now GNAT does not use a simple checksum but a
42921 CRC using GNAT.CRC32.
42923 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
42924 now and not anymore a simple checksum.

42963 * types.adb (Hex): Use lowercase for the letter part.
42965 * types.ads (Get_Hex_String): Returns the hexadecimal representation
42966 for a word. This is currently used only for CRC. In previous version,
42967 the checksum was using a representation with all letter being
42968 upper-case. With the new implementation (using CRC) we do not remove
42969 the 32th bit of the CRC, so we can have an upper-case starting letter
42970 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
42971 It is ambigous since the CRC was optional and could be followed by
42972 options like EB, EE. So now this routines uses lower-case letter for
42973 the hexadecimal representation. Strange enough only lower case letters
42974 where checked in Scan_ALI (even if this was not a possible case).
42976 * gnatvsn.ads (Library_Version): changed to 3.15a.
42978 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
42981 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
